What is this message in the buy/sell strategy column?
ProfitTrailer runs its code in cycles. When any of the following messages are displayed the subsequent checks are no longer considered. For this reason, you will only see the message closest to the top displayed in the GUI. You will not see multiple messages.
If you are unsure what the message means the Web Interface Guide explains most of them with links to the relevant parameters.
What do the Buy and Sell Buttons do?
In the Possible Buy Log (PBL) the buy button will attempt to make an initial buy. The size of the buy is determined by your DEFAULT_initial_cost setting or coin specific equivalent.
In the DCA Log the buy button will attempt to complete the next DCA buy in accordance with your DCA settings. The size of the purchase is determined by your DEFAULT_DCA_buy_percentage for the next DCA level or coin specific equivalent.
Buys may still be prevented by lack of orderbook volume.
In the Pairs Log the sell button will attempt to sell the coin at the top buy order price. If it is unable to sell all of the coins at ones it will try again at the same price two more times. If you still have remaining coins you can initiate a new manual sell however this will be at the new price point (top buy order).
In the DCA Log the sell button will attempt to sell the coin at the top buy order price. If it is unable to sell all of the coins at ones it will try again at the same price two more times. If you still have remaining coins you can initiate a new manual sell however this will be at the new price point (top buy order).
Can I purchase additional API slots?
A standard subscription comes with 2 API key slots. You can purchase additional slots for the same exchange by logging in to your account portal at https://profittrailer.com.
After purchasing an additional slot you need to redeem it with PT Assistant. Type !redeemapi in a private message to PT Assistant on Discord. After it is redeemed you can use !addkey as per the normal process outlined in the API Key Guide.
Any API key that is attached to this extra slot will display an expiration date in !listkeys. Once an API key slot expires, the API key expires, so the bot running with this API key will also expire.
PRO users receive a discounted price for each additional slot through use of a discount code. Your unique code can be obtained from PT Assistant on Discord.
Talk to PT Assistant in a private message and type !givemediscount to receive the code. Enter the code while purchasing the API slot to receive the discount.
The code will expire after 24 hours. After this time you will need to generate a new one.
Each code can be used only one time.
Not all parameters are included in the default download. Not all parameters are mandatory to have in your file either.
If you are missing a parameter, simply add it to the appropriate file. Order is not critical but for ease of use you can group similar parameters near each other.
On small screens some columns are collapsed to save space. You will know if columns have been hidden when you see in the first column.
The information can be made visible again by clicking to expand as seen below.
How do I cancel Pending Orders?
Pending orders can be cancelled using the cancel button in the Pending Log or manually on the exchange by cancelling the open order.
You may find that the pending order is automatically created again. This is because the pending trigger is still true, you will need to adjust your settings or disable the applicable trigger and then cancel the order.
Which Will My Bot Use?
Pending orders can be configured to cancel automatically in some circumstances. ProfitTrailer has parameters in both the Pairs and DCA configs to cancel pending orders, but which settings apply?
The logic that applies to your pending order depends on whether or not the coin is DCA enabled. A coin is considered DCA enabled in any of the following circumstances.
In all of these cases the DCA settings are applied to the pending orders: i.e DEFAULT_DCA_combined_cancel_pending_trigger and DEFAULT_DCA_cancel_pending_trigger are used.
In all other cases the Pairs settings are used: i.e DEFAULT_combined_cancel_pending_trigger and DEFAULT_cancel_pending_trigger are used.
Why am I getting these expired orders in my logs?
Expired orders are part of trading. If the order book is thin, you will most likely get expired orders as the bot places limit orders when buying and selling.
Use DEFAULT_min_orderbook_volume_percentage or DEFAULT_DCA_min_orderbook_volume_percentage to prevent the bot attempting to make buys when the order book volume is low.
For selling, depending on the amount of coins you hold, you might also get expired orders, which in some cases are just partial sell orders.
Why are my coins in WATCHMODE?
Please refer to the Pairs Log section of the Web interface Guide.
Where do I find my License?
You ProfitTrailer License is emailed to you usually within 1 hour of your payment being confirmed on the block chain.
The email is titled "ProfitTrailer License Activation" if you would like to search you inbox or junk folder for it.
How do I enable/disable the web GUI Config?
The Config is enabled in the Web GUI by default however it still required you have a password set in order to use it. If you don't have the password set, or password is disabled, or you are logged in as guest, config will be disabled.
Why is my Possible Buy Log Empty?
There are a number of reasons the Possible Buy Log might be empty.
DEFAULT_trading_enabled = false. This is the default setting when you download the bot as a safety measure.
you have missing or invalid indicators.properties.
No remaining pairs meet your buy criteria.
you have a high DEFAULT_min_buy_price setting and no more coins meet that minimum price.
server.start_trading_delay will stop the PBL populating until it times out.
How can I set or reset a password?
You will be prompted to set a password when first booting up the bot. The password is stored in the ptdb.db file in the ProfitTrailer/data folder.
If you do not wish to have a password at all add the following to your application.properties file.
Note: you will not be able to change configuration files without a password.
How can I allow guests to view my bot?
By selecting Change Passwords in the Web Interface Settings you can create a password for the Monitoring page separate from the Admin password. Guests will have access to the GUI but the Config options will not be available. This password is stored in the ptpw-monitor file and can be deleted to remove guest login ability.
Guests will not be able to see your configuration files, reset the passwords or stop the bot.
How can I Reset the Price of a Coin?
You can use the HotConfig to set a bought price. HotConfig is a place to run one-time settings in the window to take certain immediate actions in the bot. Read all about it here.
ProfitTrailer resets the DCA count of a pair when the bot makes a new purchase. By manually purchasing you have bypassed this step.
How can I Reset the DCA count?
You can use the HotConfig to do this. HotConfig is a place to run one-time settings in the window to take certain immediate actions in the bot. Read all about it here.
What does a trigger value of 999 mean?
If ProfitTrailer is unable to find a default (or DCA level specific) buy/sell_value or buy_trigger for the coins next action you will see 999 or -999 displayed. This is a visual cue that something is missing.
TCV is calculated by adding up the balance plus the actual value of the purchases that appear in the Pairs, DCA, and Pending logs. It excludes Dust log value, so it may not match your exchange balance exactly.
How do I log out of ProfitTrailer?
Click the Settings Cog in the Web GUI to access the settings tab and the Log Out button.
How do I stop the bot?
There are several methods for stopping the bot safely.
2. Append /stop to theport in your browser URL. The link will not work if server.disable_password is true.
3. Stop the bot from the command line/terminal by typing CTRL-C (cmd+c on MAC).
4. In pm2, stop the bot by finding the pm2 process id (pm2 list)and stopping it with that. For example if your bot is process id 2, the command would be (in the terminal window) pm2 stop 2.
Do I have to stop the bot when changing settings?
Only changes made to your API keys will require the bot to be restarted. Changes made to all other properties via the HotConfig or to the files directly will be detected automatically.
How do I save and load different configurations?
Clicking on will reveal the configuration screen.
If you wish to edit a particular config click the Orange config name to reveal a dropdown menu. Select the config you wish to edit and make changes as desired.
Press the button to save your changes before navigating to any other page.
Select the Settings Cog and then choose Settings from the two options at the top of the menu.
You can then click the config name to change the active configuration. The bot will switch to the new config straight away.
Click the button in the Settings Menu or navigate to http://localhost:8081/setup (adjust port/IP if necessary).
NOTE: Do not use spaces when naming your configurations.
Public - Choose from our database of public configs and copy it to your bot giving it a unique name.
Saved - Choose from one of your own configs that you have already created in the past.
If you have a config you want to base it on select it from the dropdown menu.
Click the button to choose a name for your new config.
Your newly named config will now be displayed and you are free to edit it.
Public configs can be copied from the setup screen. See Loading a Config above.
You are loading a static copy of the config and will not receive any automated updates to it. You can modify it yourself if you desire to make and adjustments. If the config does get updated in the future you can make the changes manaully, or import the newer config and save it as a separate config for your bot.
If you wish to delete a particular config click the Orange config name to reveal a dropdown menu.
Select the config you wish to delete and then click the button.
You will not have the option to delete the active config.
How do I set up ProfitTrailer to trade a Different Market?
Below are the main pairs and dca properties files changes you would need to make. In this example we will change from BTC to USDT on bittrex.
Note: not all possible parameters are included in this example. Parameters needing to be adjust for USDT values are marked with *.
How do I vary a setting per DCA level?
This is achieved by entering the values into dca.properties multiple times and appending _x to the end where x is the dca level.
If a coin has DCA'd (2) times then it will use the _3 values for the next buy action and the _2 values for the next sell action.
In the examples below the optional default parameter will be used if a _x parameter cannot be found for the next DCA action.
If no _x parameter exists for the next dca level and no default parameter exists the bot will return a value of +/-999 ultimately nullifying the parameter.
This would normally result in a DCA sell with a minimum 1.5% profit however we can lower the desired minimum profit for each DCA level.
Without explaining the Math, the folowing example would buy approximately the same number of coins every DCA level, matching the DEFAULT_initial_cost amount.
How do I Change Settings on a Single Coin?
All properties starting with "DEFAULT_" in the pairs.properties or dca.properties files can also be configured as "coin_" to act on a specific coin. This is useful when you want to do something (or a series of things) to one or more coins, differently from your default settings.
Most options can be turned off by indicating "false" or setting a value of 0, and turned on by "true".
In addition to DEFAULT_trading_enabled = true you would add LTC_trading_enabled = false to the Pairs Config.
Normal trading will be unchanged but LTC will no longer be trade-able. LTC will appear in the pairs log with a buy strategy of WATCHMODE or if hidden_pairs = ALL it will no longer appear in the GUI.
Example: I want to panic sell a single coin.
To panic sell TRX, add TRX_panic_sell_enabled = true to the Pairs Config.
This changes the buy value for strategy A for LTC and prevents LTC from using the B strategy.
How does trailing profit work?
Your GAIN strategy sell_value is the amount you want as profit. If you don't set trailing_profit, as soon as the price reaches that amount the bot will attempt to sell.
Now you say. I want 0.5% trailing_profit. meaning. I want to risk 0.5 in order to gain more. Why risk ?
If you have sell_value at 2%, the bot will not sell anymore when it reaches 2%,because we gave it 0.5% breathing room, so, if the price goes to 2.3%, we mark that down as the highest value. Now the price goes down to 1.9%, the bot won't sell, because it is under our 2% gain value and 0.4% change is still within our breathing room: 0.4% = 2.3 - 1.9 That is the risk we are talking about. The profit reached 2% but the bot did not sell because of trailing profit.
Now if the price continues to go down, you are left with a bag. But not this time!
The price goes up to 2.8% then 3.5%. So we mark down 3.5% a our highest value, then the price reaches for 3.7% profit!
So when will we sell? Our gain was set at 2%!
Our trialing profit was set at 0.5% and 0.6% is > 0.5% so enough risk. Now we sell!
Please see this information in the VPS area here.
Sell Only Mode (SOM) can be automatically turned on when the triggers in the Pairs Config are tripped by rising or falling market, or by consecutive buys.
But what if you want to turn off SOM anyway?
1) Determine why the SOM is triggered by holding the mouse over the SOM indicator in the browser window and read the message that pops up. This will guide you to which trigger to adjust.
2). Change the trigger value. For example if the price_rise_trigger has tripped, and the current market has gone up 5%, and your trigger is set for 4%, you would need to change your trigger to more than 5% and also change the recover trigger, price_rise_recover_trigger in this case, to more than 5%.
The options below only work if you have set a password for your GUI!
Be sure to change the port (8081) to the port you are using on your bot.
This disables global sell only mode, but it will reactivate on next buy attempt if the SOM trigger condition is still true.
Copy and paste the following line into your browser address bar and hit enter.
WARNING: Using multiple instances of ProfitTrailer on one exchange account is not recommended. The bot is not designed to work alongside another instance. Besides multiple untested side effects and trading conflicts within the bot itself, there is a high likelihood of flooding the exchange with API calls and getting banned from trading, putting your investment in the bot and in your time and effort at risk.
This guide assumes that you are using a second instance on 1) a new account on the same exchange (to trade USDT or ETH for example), or 2) to create a new instance on a different exchange using a different exchange license (or multi-exchange license).
For help with setting up a bot on a VPS, please see this guide. This has additional info on setting up a second instance in a VPS environment in Linux, and managing that remotely in a Windows environment.
Setting up a second instance of the ProfitTrailer bot is simple.
Change the server.port to another unique, unused port. The default is 8081. For example, make the next bot use 8082, and the next one 8083, etc. If you get an error that the port is in use, change it.
If you are changing to a new exchange (BITTREX, POLONIEX, or BINANCE), then enter the new exchange in trading.exchange.
Enter two new sets of API keys and secrets.
If you have not yet registered a new default_api_key you will need to talk to PT Assistant on discord and register it. Go here to see that process: API Key Guide.
If you are running the bot in test mode, change the test mode setting in application properties to true.
4. Any other config changes are optional. You can setup new notifications bots etc now if desired.
5. When running the new bot for the first time Ensure you choose a new UNIQUE name for the config. You should be prompted to choose/load a config when it first boots up. SeeSave/Load different Config. Make changes to the pairs config, DCA config and indicators config in the GUI after the bot is running.
Why don't we allow people to sell PT Settings?
While we don't give out settings beyond a basic startup profile with your PT purchase, we do coach and train people how to create good settings. Some of our official resellers give away some basic settings for free that will give you an idea on how to manipulate the settings for your needs. We also encourage customers to share their knowledge, as that benefits the most people.
Our belief is to "teach a man to fish for life" instead of just "giving him fish for a day." Our goal is to provide support that is from known and validated individuals that are trusted. We cannot do that if we have random resellers PMing all of our customers, selling them things.
With these goals in mind, we do not support the selling of settings for ProfitTrailer. While we cannot police the entire internet, we will not support it here, instead, choosing to support and guide our users. There is no way for us to stop someone from making poor settings, which reflects poorly on PT. Instead, we choose to rely on our reseller to have good, free settings.
Dust is the technical term for small amounts of a given coin that are below the minimum trade-able levels set by each exchange.
Binance has a way to consolidate dust. Just go to your Funds > Balances page and look for the button up top.
Keep your initial trade amount a few percent higher than the minimums allowed by the exchange. e.g if minimum is 0.001 use 0.0011 or higher.
On Binance the fees are taken out of the coin you purchase which can leave you with partial coins that can't be sold. Binance has their own coin called BNB which can be used for fees instead and also halves your fee. On Binance, dust is unavoidable unless you buy and hold some BNB coins. Just 1 or two is plenty to start with and you can top it up as it gets low. Ensure you disable trading for BNB otherwise the bot will try to sell it.
Having referral rewards deposited to your account can leave dust.
Where are the database backups located ?
Backups are stored in the /data/backups folder, inside the ProfitTrailer Main Folder.
What / Where is an ordersettings file?
Every time ProfitTrailer makes a buy or sell it creates a record of the settings that it was configured to use at the time. Support may ask you for a copy of a particular ordersettings file in order to troubleshoot your issue.
You will find the ordersettings folder in the main ProfitTrailer folder. Sort the files by date modified in order to help match them up with orders on the exchange/bot.
How do I take and upload a screenshot?
Each Operating system requires different steps to take a screenshot and there are many ways to take a screenshot in most cases. We will focus on how to take a screenshot of a selected portion of your screen.
Any modern Windows OS includes the Snipping Tool. Search for this tool in the start menu or press Shift+Windows+S so enter snipping mode.
Click New, The pointer changes to a crosshair.
Move the crosshair to where you want to start the screenshot, then click and drag to select an area.
When you've selected the area you want, release your mouse or trackpad button. To cancel, press the Esc (Escape) key before you release the button.
Press Shift-Command-4. The pointer changes to a crosshair.
Move the crosshair to where you want to start the screenshot, then click drag to select an area.
While dragging, you can hold Shift, Option, or Space bar to change the way the selection moves.
Find the screenshot as a .png file on your desktop.
You can upload the screenshot to a channel or a private chat in several ways.
If the screenshot is copied to your clipboard you can paste the image directly into discord.
You can browse for and upload a file buy clicking the plus symbol in the message box.
How many different Configs can I have saved?
A configuration (or Config) is a complete set of settings comprising of Pairs, DCA and Indicator settings. The number of saved Configs you can have is determined by the number of instances (API keys) your license supports.

En mathématiques, une paire de matrices commutantes est une paire {A, B} de matrices carrées à coefficients dans un corps qui commutent, c'est-à-dire que AB = BA.

L'étude des paires de matrices commutantes a des aspects tout à fait élémentaires et d'autres qui font l'objet de recherches en cours. L'énoncé de certains problèmes étudiés est assez élémentaire pour être présenté au niveau de la première année d'études supérieures. En voici un exemple :

Une matrice nilpotente est une matrice dont une puissance est nulle. On sait qu'une telle matrice est semblable à sa réduite de Jordan. Supposons la matrice  nilpotente, sous forme réduite de Jordan, avec des blocs de taille donnée. Quelle peut être la taille des blocs de Jordan des matrices nilpotentes qui commutent avec la matrice donnée ?

Bien sûr, la solution, elle, n'est pas élémentaire.

Résultats élémentaires
L'ensemble des matrices commutant avec une matrice  (l'algèbre des matrices carrées d'ordre n à coefficients dans K) est une sous-algèbre de , appelée commutant de A et notée C(A) ; C(A)  contient en particulier tous les polynômes , ainsi que A si A est inversible.

Si  et  sont semblables, c'est-à-dire que , alors , avec .

Matrices commutant avec une matrice diagonalisable
Si B commute à A alors B laisse stable le noyau et l'image de tout polynôme en A, en particulier les sous-espaces propres de A.

Si, inversement, B laisse stable chaque sous-espace propre de A alors sur chacun d'eux, la restriction de A est une homothétie donc commute à celle de B, donc AB – BA, étant nul sur chaque sous-espace, est nul sur leur somme.

Si cette somme est l'espace tout entier, on a donc caractérisé les matrices qui commutent à A :

Plus concrètement : si A = PDP pour une certaine matrice inversible P et une matrice diagonale D de la forme
(où les d sont deux à deux distincts et où I désigne la matrice identité de taille n) alors, une matrice commute à A si et seulement si elle est de la forme PCP, avec C diagonale par blocs :

(où, pour chaque k, le bloc C est de taille n).

En particulier :

En effet, dans ce cas, tous les blocs sont de taille 1 : C = (c) pour k de 1 à p = n, or le théorème d'interpolation de Lagrange prouve qu'il existe un polynôme Q tel que pour k de 1 à n, Q(d) = c. On a donc C = Q(D). Comme A = (PDP) = PDP, on a également B = Q(A).

Matrices commutant avec une matrice non diagonalisable : un exemple

La situation devient très compliquée si on considère les matrices commutant avec une matrice  non diagonalisable.

Supposons d'abord que  soit une matrice de Jordan, de plus nilpotente. Un calcul élémentaire montre que toutes les matrices qui commutent avec  sont des matrices de Toeplitz triangulaires supérieures, c'est-à-dire de la forme

Si on prend comme  une matrice diagonale par blocs, dont les blocs sont des matrices de Jordan nilpotentes, il se passe des choses assez surprenantes. Notons  les blocs diagonaux de .

En calculant par blocs AB et BA, on voit que tous les blocs de la matrice , découpés d'après la structure des blocs de la matrice  doivent vérifier la relation de commutation suivante:

Les blocs diagonaux de  sont donc triangulaires supérieurs et de Toeplitz, mais les blocs hors diagonale ne sont pas nuls ; ils sont de la forme

si  et de la forme

dans le cas contraire.

Rien n'indique de relation simple entre les sous-espaces caractéristiques (ou sous-espaces propres généralisés) de  et ceux de .

Prenons le cas suivant, très simple. Soit  donné par

et choisissons la matrice  suivante :

Cette matrice commute avec . Ses valeurs propres sont  et , qu'on suppose distinct de . Le sous-espace caractéristique relativement à la valeur propre  est engendré par les vecteurs

et le sous-espace caractéristique relatif à la valeur propre  est engendré par les vecteurs

Le rapport entre les sous-espaces caractéristiques de  et ceux de  n'est donc pas évident.

Variété commutante

Soit K un corps et soit E = M(K). La variété commutante est l'ensemble des couples de matrices  telles que . Cette variété algébrique est définie par n équations quadratiques à 2n inconnues. Pendant longtemps les propriétés de cette variété sont restées mystérieuses. Murray Gerstenhaber a montré en 1961 que cette variété était irréductible. R. Guralnick a remarqué en 1990 que l'essentiel de cette preuve avait été donné en fait dans un article de T. S. Motzkin et O. Taussky.

L'article de Motzkin et Taussky porte essentiellement sur les faisceaux de matrices.

Tout un pan de l'article de Gerstenhaber fait appel à des techniques de théorie des représentations, en particulier les partitions.

Il est surprenant de constater que l'étude des paires de matrices commutantes continue à être un sujet de recherche actif dans des domaines variés : algèbre commutative, algèbre numérique et computationnelle, théorie des représentations. Citons par exemple un article de Baranovsky, qui montre que la variété des paires de matrices nilpotentes est irréductible. Des travaux de 2007 et 2008 examinent la structure de Jordan des matrices commutant avec une matrice nilpotente donnée. Le sort des sous-espaces propres est encore peu abordé, mais on peut citer par exemple un travail de Heinrich Kuhn en 1977. Sachant que les problèmes de vecteurs propres et de vecteurs propres généralisés sont toujours plus difficiles que les problèmes de valeurs propres, on voit qu'il reste du travail.

Matrices qui commutent « presque »

Peter Rosenthal a posé la question suivante en 1969 ; si le commutateur de deux matrices  et  est petit, sont elles proches d'une paire de matrices qui commutent ? La question est précisée comme suit : peut-on trouver pour tout , un  tel que pour tout entier , si  et  sont des matrices de norme inférieure ou égale à , vérifiant , alors il existe une paire de matrices commutantes  et  telles que .

La réponse est positive si on permet à  de dépendre de .

La réponse négative, pour les matrices complexes, est due à Man Duen Choi, en 1988. Il énonce ainsi le théorème suivant :

Pour tout entier , il existe des matrices ,  et  telles que , ,  et cependant , pour toute paire de matrices commutantes  et .

Retooling older buildings: A popular trend for urban office space
April 11, 2018 /in Hot Topic, News /by Shenehon Company
By: Daniel L Wojcik
The retooling and repurposing of older buildings has become an increasingly popular trend in urban office markets across the country. Companies are investing in modern office spaces as a tool to attract and retain young talent in the workforce. A shortage of modern Class "A" office space has opened the door for expansive renovations of older, historic buildings to add new amenities and features while retaining the building's original character and charm. Companies are beginning to see the importance of amenities and attractive, exciting workspaces that appeal to employees. Popular renovation amenities include: on-site parking; locker rooms; bike storage; on-site coffee shops/bars; open floor plans; and bright, collaborative spaces with lots of natural light.
A great example of this new trend toward repurposing older buildings is the Highlight Center project that was recently completed in the Northeast Minneapolis submarket by Hillcrest Development. The Highlight Center was a major redevelopment of aging buildings that originally functioned as a light bulb factory and housed the Minneapolis Public Schools Headquarters until 2014.
The renovation included razing buildings on the site to open up space for surface parking while keeping the core buildings intact. The process of reusing the original structures retained the character and charm of the buildings while renovations inside transformed and modernized the space. The development team added a slew of amenities, including: bike storage and locker rooms for commuters; an on-site coffee shop and brewery; open, bright floor plans; and ample free surface parking.
Many companies that would traditionally look in the North Loop area are drawn to the Northeast Minneapolis market in search of more favorable rents. The Highlight Center created the perfect blend between price and attractive amenities in a newly renovated, modern office building. The new space attracted Sports Engine, a software company for managing sports leagues online, which became an anchor tenant occupying nearly 32,000 square feet of office space. The signing of Sports Engine was a catalyst for other tech and creative companies that followed suit and helped the property reach 99% occupancy after its first year. Sports Engine leased an additional 7,500 square feet of space approximately a year after signing the initial lease at rates nearly 11% higher than their initial signing. Rent increases have continued as demand increased at the property, with recent signings showing strong growth from less than 12 months earlier. Northeast Minneapolis' close proximity to the Minneapolis Central Business District and cost-effective space options provide a compelling choice for growing companies.
For the most part, repurposing and renovating of older buildings is happening in urban neighborhoods where younger members of the labor force are choosing to live and work. Developers' responses to increased demand for modern workplace in urban locations will have a direct impact on asset value in the future. The success of the Highlight Center project and interest in the Northeast Minneapolis market as a cheaper, more flexible alternative to the Central Business District or North Loop neighborhoods of Minneapolis bodes well for the area. It will be interesting to keep an eye on the Northeast Minneapolis market to see if other renovation projects emerge, hoping to build on the success of the Highlight Center.

Responsible and Sustainable Business Lab
Unit(s) of assessment: Business and Management Studies
Research theme: Sustainable Futures
School: Nottingham Business School
The RSB Lab leads multiple research projects under each of the following streams on various dimensions of business' role in fostering sustainable societies by means of responsible values-driven business. The RSB Lab's vision is to carry out research that combines academic excellence with impact. Further details on how the RSB Lab is driving change towards sustainable and responsible business practices can be found on the RSB Lab website.
Critical Perspectives on Responsible and Sustainable Business
Across each of our streams the RSB Lab draws on multi-disciplinary perspectives including arts, humanities and the natural and social sciences to explore alternative ways of organising, and creative ways of thinking about capitalism and its practices. We challenge managerial orthodoxy about "sustainable business", and question the methods and approaches that can lead to the marginalisation of alternative ways of conceptualising the relationship between business, sustainability and ethics.
The RSB Lab plays a central role in building a research culture by:
Developing the research skills and capacities of our early career researchers;
Hosting sessions on publishing, methodology, academic writing, and bespoke research seminars with leading academics and editors;
Providing internal research support on paper writing and the development of grant proposals;
Pursuing innovative research projects and grant proposals in line with the RSB Lab vision and critical approach.
Stream 1: Ethics, Innovation and Entrepreneurship
This stream is led by Professor Mollie Painter and Emrah Karakilic, and addresses important research questions on how processes, dynamics, habits and managerial thinking may undermine ethics and sustainability. The overriding goal is to pioneer research that challenges everyday assumptions through philosophical thinking and practice.
Research priorities include:
Processes and dynamics that may undermine ethics and sustainability;
Upcycling as an instance of social entrepreneurship and as a waste management strategy;
Understanding why certain unethical practices and unsustainable habits persist;
Challenge business practitioners to question ingrained ways of thinking and being;
Draw on philosophical thinking and practice to challenge everyday assumptions.
Stream 2: CSR and Corporate Governance
This stream is led by Dr Wendy Chapple, and focuses on core business practice, and drivers and processes that underpin business engagement with responsible and sustainable business agendas. This stream addresses important research questions on corporate outputs and impact, through the lens of multi-disciplinary research on corporate responsibility, corporate sustainability and corporate governance.
Integrating sustainability across the value chain and global production networks;
Developing sustainability models for business of various sizes across the globe;
Business partnerships and international development;
Understanding integrated reporting formats and other dimensions of sustainability accounting and control;
Social and environmental strategy;
Accountability and enterprise risk management and responsible investment.
Stream 3: Teaching and Learning
Led by Professor Mollie Painter and Elmé Vivier, the teaching and learning stream integrates research on ethical organizational culture, ethical decision-making and leadership, with the design and delivery of executive development programmes. Research in the stream focuses on enabling managers and employees to speak up in the face of ethical wrongdoing, and to find responsible and systemic solutions to ethical dilemmas.
Understanding moral behaviour and decision-making
Giving voice to values in everyday business practice
Speaking-out and whistleblowing
Ethical leadership in the African context
Finding ways to collaborate across organisations and sectors
Research led by Professor Petra Molthan-Hill links to this stream, on the foundations and strategies that are used in business schools and universities when teaching students about values-driven, responsible and sustainable business.
This includes leading initiatives that prepare students to deal with the dilemmas that managers and employees face in making choices that are technically sound, ethically responsible, sustainable, and culturally sensitive. See also the Green Academy.
As people learn that climate change is anthropogenic, they realise they hold the key to mitigate it by embedding the right high-impact climate solutions and institutional policies addressing all SDGs and creating economic, social and environmental benefits.
Addressing this gap in the provision of climate change mitigation education, Carbon Literacy Training for Educators, Communities, Organizations and Students (CLT-ECOS) - a virtual Train-the-Trainer has been developed and upscaled by NBS, in collaboration with the UN Global Compact PRME Working Group on Climate Change in order to empower people to embed high-impact climate solutions in their personal, professional and community life. CLT-ECOS has been awarded Gold for Sustainability at the 2022 Wharton-QS Reimagine Education Awards.
Find out more about Carbon Literacy Training for business schools.
The most recent book authored by Petra can be found here. This book demonstrates how stories and storytelling can be consciously embedded into the curricula of any academic discipline in Higher Education to co-create a better future.
Stream 4: Energy and the Environment
Anna Ozolina is a Research Fellow in Sustainable Mobility and manages this stream in collaboration with other colleagues. This collaborative engagement helps to ensure that interdisciplinary perspectives are fully integrated in its research on energy and the environment, and sustainability management and strategy.
Sustainable Mobility - Ultra Low Emission Vehicle technology, strategy and policy in collaboration with Professor Rob Ackrill of the Centre for Economics, Policy and Public Management (in particular in relation to Energy, the Environment and Resources research strand), and Dr Michael Zhang of Centre for International Business, Strategy and Decisions. In addition, Ackrill and Zhang are co-Editors-in-Chief of 'Sustainable Mobility', an open access journal published by Sciendo.
Cooperative group modelling, and social and environmental strategy
Accountability and enterprise risk management.
The RSB Lab works with an extensive network of associates, visiting scholars and collaborators, both within NTU and the wider academic and practitioner community. The following provides brief examples of RSB Lab collaborations:
REAL-Network (Research on Ethical African leadership Network) and the Values-Driven Leadership (VDL) training programme
The REAL-Network brings together international academics and African leaders from across sectors who are alumni of a bespoke executive leadership programme entitled "Values-Driven Leadership in Africa". The REAL-Network is an online executive leadership development and research network led by the RSB Lab.
External collaborators include:
ABIS (the Academy of Business in Society);
University of Stellenbosch Business School, South Africa;
Gordon Institute of Business Science, South Africa;
Strathmore Business School, Kenya;
Personnel from business and third sector organisations in Egypt, Kenya, South Africa and Nigeria.

WE-DARE! (Women's Equality: Digital Access and the Right to Expression)
WE-DARE (Women's Equality: Digital Access and the Right to Expression) has been funded by a first phase UKRI GCRF DIDA (Digital Innovation for the Development of Africa) grant. Phase 1 (May 2020 - April 2021) granted seed funding to establish networks across a range of partners.
WE-DARE explores the intersection of women's rights and digital innovation in Africa. The RSB Lab launched the project in partnership with the Gordon institute of Business Science, University of Cape Town, Stellenbosch Business School and Lagos Business School, alongside several civic and tech organisations including:
WARIF
WomaNiko
WI connect
Sonke Gender Justice
Praekelt
Triple Black Agency
Affect Lab
1000 Women Trust
WE-DARE Phase 1's findings suggest that though many attempts have been made to address Gender-based Violence (GBV) via hotlines, apps, and other resources, women often don't have access to these digital means. In fact, it may put them more at risk. Cultural and social barriers also exist that block the use of these technologies. In addition to this, most women do not know of a safe space to go if they experienced GBV. As such, more practical, grassroot solutions are needed to reach women and to co-create solutions to GBV with them. Our preliminary research findings suggest that there is no one-size-fits-all solution. Instead, local communities need tailor-made and co-created solutions, to ensure that all women and GBV survivors can access the moral support, information and help that they need.
In collaboration with our partners, specific project proposals are being developed to seek funding to continue our network-building efforts. This includes projects focused on co-creating tailored solutions to GBV in interaction with local communities, disseminating information, educating the next generation of young people around their rights, and providing practical support for survivors.

Values Driven Leadership (VDL) training programme and impact research
Research on Ethical African Leadership Network (REAL-Network), is a maturing partnership between academics and practitioners in African DAC countries committed to combating ethical failures that can undermine service-delivery in various sectors. A key activity of the network is the delivery of the 'Values-driven leadership' (VDL) executive leadership training programme, which addresses the problem of systemic ethical failure in low and middle income (LMIC) economies.
The VDL programme is the result of collaborations between academic and non-academic partners (business, government and NGOs) in South Africa, Kenya and the UK and it seeks to empower leaders to give 'voice to their values' (GVV) when confronted with systemic pressures to act unethically. (It draws upon Mary Gentile's novel GVV pedagogical approach that equips leaders to develop levers of influence, persuasive responses, and alternative scripts that help them counter the rationalisations of unethical behaviour that they may face).
See also 'Collaborations' for further details.
Speak-out project
The RSB Lab and the Gordon Institute of Business Science (GIBS) in South Africa collaborated on a critical research project: Speaking-out against ethical failures. The project sought to better understand the experiences of people who have challenged ethical failures in their organisations. It aimed to develop practical insights and recommendations, identifying how to more effectively enable and encourage employees to speak out.
The project formed part of the Research on Ethical African Leadership Network (REAL-Network), a maturing partnership between academics and practitioners in African DAC countries committed to combating ethical failures that can undermine service-delivery in various sectors.

The network-building project, titled WE-DARE explores the intersection of women's rights and digital innovation in Africa. The RSB Lab launched the project in June 2020, in partnership with the Gordon institute of Business Science, University of Cape Town, Stellenbosch Business School and Lagos Business School, alongside several civic and tech organisations.
The main goal of the research is to explore how access to digital platforms and innovation can protect and further basic women's rights in Africa, focusing on addressing violence against women in the South African context. The main goal of the research will be achieved by reaching the following objectives:
O1. understanding the role of digital rights in addressing the effects of gender intersectionality
O2. enabling the employment of digital innovation to enhance participation and access for women across societal institutions
O3. protecting women's rights to safety and equality
O4. enabling participation in civic life and access to democratic institutions
O5. improving women's quality of life
The RSB Lab have been building the network, running engagements online and conducting 'in person' community focus groups in South Africa and Nigeria though their NGO partner networks.
The RSB Lab hold regular meetings with guest speakers throughout the year, with the aim of supporting early researchers, encouraging interdisciplinary working and allowing a platform for enriching research debate.
Throughout 2020 and 2021, The RSB Lab and the Work Futures Research Group, School of Social Sciences, are collaboratively running a new interdisciplinary seminar series, called the Subversive Seminar Series (ISSS). The seminars focus on provocative and polemical ideas/works, aimed at challenging contemporary orthodoxies in various fields, allowing us to listen and learn from our colleagues working in different disciplines or departments.

Summer 2009 issue of Kaatskill Life
NOT ALL ABANDONED PASTURES BECOME FOREST
by Michael Kudish
When I was in college, we were taught in ecology classes that when old fields and pastures were abandoned, trees soon moved in and the land became forested. The doctrine was called succession and climax. More recently, ecologists in other parts of the United States have found that this doctrine does not always work. In the Catskills, I also find that this doctrine is not necessarily true. Natural reforestation does happen some of the time but not all the time.
My suspicions of exceptions to the doctrine began in 1970 while I was exploring the Catskills for my dissertation on the history of the region's forests. I found rough-stemmed goldenrod (Solidago rugosa) at an elevation of 3185 feet on the east slope of Sugarloaf Mountain along the Devil's Path. "What is this doing way up here?" I wondered. This species of goldenrod typically grows at much lower elevations – along roadsides, in fencerows between pastures, and in abandoned fields. How did the plants get up here on the mountain, at least a mile from the nearest old field?
As I explored the Catskills further, I found more and more such remote, high-elevation (3000 to 3800 feet) populations of rough-stemmed goldenrod, sometimes mixed in with its cousins, the lance-leaved goldenrod (Euthamia graminifolia) and the flat-topped white aster (Aster umbellatus, now Doellingeria umbellata). On a few occasions, Canada goldenrod (Solidago canadensis) and joe pye weed (Eupatorium maculatum) were present. I have almost twenty such small, naturally-open sites on my list now.
As my more recent studies focus more on the middle and lower elevations of the Catskills, I find these same plants in great abundance in old beaver meadows. When beaver ponds had flooded the forest, the trees drowned and died. Later, after the beavers left, the dams gave way and the waters drained. These plants then invaded the sunny meadows. They occur abundantly as well on portions of floodplains where forested areas were also destroyed by excessive volumes of water.
Whether it be a high-elevation site, a beaver meadow, or a flood plain, these native, shade-intolerant plants always grow in open sunny areas. All of these sites are naturally-occuring, many in first-growth forests (see Kaatskill Life, Winter 2008-2009, pp. 14-19); none was ever cleared for pasture or crop land.
Yet, these places have the same plants as many abandoned fields and pastures. Native Americans created very few open fields in the interior of the Catskills; forest was first cleared for crop and pasture land with the advent of settlers of European origin mainly after the Revolutionary War.
How did these plants migrate from the old fields and pastures into the beaver meadows, flood plains, and up to small openings nearly at the tops of the mountains? It finally occurred to me that I was thinking backwards. They didn't. They originated up on the mountainsides, in the beaver meadows, and on the flood plains and migrated into many abandoned fields! Each seed of these plants is inside a small fruit equipped with a parachute (much like dandelion, a non-native, European cousin). Travel by wind is quick and easy.
How can such places high up on the mountains, beaver meadows, portions of flood plains, as well as many abandoned fields and pastures, remain nearly free of trees even after periods from as long as a half-century to a century or more?
The best examples are old fields which became part of the New York State Forest Preserve. If we know when they were acquired, then we have a record of at least how many years these lands have not been planted with crops, mowed, grazed, or burned. I am compiling lists of these old fields for future historians who wish to see how long these sites stay open.
One old field in Lot 13 along and near the west end of the Huckleberry Brook Trail, on the south side of Cold Spring Hollow, had been purchased by the state between 1924 and 1938 and is still open.
The Devil's Acre, in the col between Hunter and Southwest Hunter Mountains, was a clearing made by the Fenwick Lumber Company during the first two decades of the twentieth century. It became Forest Preserve about 1921 and parts of it are still open.
An old field near the headwaters of the Batavia Kill, on Lot 62 at the junction of the trails which descend from the Batavia Kill Lean-to and from the Black Head-Black Dome col, was acquired in 1913 and is still open.
How do these places stay open for so long? Have you ever tried to push your way through a thicket of rough-stemmed goldenrod, lance-leaved goldenrod, Canada goldenrod, flat-topped white aster, and/or joe pye weed in late summer or early fall when the plants are at least as tall as you are? Look at your feet when you do so. How many tree seedlings do you see under the thicket, or young plants of any other species for that matter? These five species of the Composite Family are perennial herbs – that is, the roots and underground portions of stems live for many years – decades to centuries. Each spring they send up, from buds on underground stems, above-ground stems bearing leaves, flowers, and later fruits. They spread rapidly by these underground stems as well as by seed.
Blackberries and raspberries (Rubus spp.) are in the Rose Family and unrelated to the Composites. Their life cycle is different: they are biennials (they live two years), rather than perennials, with overwintering buds on above-ground stems called canes. Yet they grow with such density that they have the same effect of inhibiting tree reproduction as the composites.
Once established in an old field, open floodplain, or open beaver meadow, all these plants spread rapidly and produce huge numbers of above-ground stems in great density, thousands and thousands per acre. They can shade out and choke out tree seedlings and other plants; they can absorb nearly all of the available water and mineral nutrients from the soil.
Some ecologists believe that goldenrods and asters are also allelopathic, i.e., they produce biochemicals that retard or prevent the growth of other competing plants. But even if no allelopathic chemicals are produced, the sheer intense physical competition is enough to crowd out almost all other plants including tree seedlings.
Why do some old fields and pastures become forested and others not? The future of the field or pasture depends on what plants seed in first after mowing, grazing, or crop planting ceases. If trees seed in first, the old field will become a forest. In a half-century to a century or so, the young forest will consist typically of aspens, birches, red maple, black cherry, white ash, shadbush, hawthorns, pines, and sometimes oaks. In about 150 years, the old field will begin to resemble the forest which preceded the agricultural clearing – a northern hardwoods beech-sugar maple forest often with hemlock.
If goldenrods, flat-topped white aster, joe pye weed (in the wetter places), blackberries and raspberries seed in first, trees watch out! These plants can maintain that old field, pasture, beaver meadow, flood plain, and high-elevation opening treeless for centuries.


An assimilation of photographs taken at various stages of the construction of the second stage of NeverEnuf, a garden (G scale) layout situated near New Delhi. Stage two was a single track loop around a miniature town which also has a circus. The viaduct and the arch bridge are scratchbuilt. So are some of the structures in the town.
The video documents the building process of a garden railway called NeverEnuf. Stage 1 was built around a hill and has a ropeway, water body and traversable gradients.
Easy steps to create viaduct walls and portals for tunnels from cement. Drawings in actual scale are available for free download from www.railmodellingindia.com. Simple process, great result!

Trail in Buenavista del Norte
Fancy a seaside walk with salty breeze, mild climate and fantastic views? This trail in Buenavista del Norte in northwestern Tenerife is a real insider tip. On your way you meet only few tourists and explore the rural surroundings of Buenavista del Norte.
Point of departure is the historic city center from where you walk along the rough coast to an unspoiled beach with a panoramic restaurant. You follow an idyllic path through (almost) untouched nature alongside a green golf course, with beautiful views especially over the wide ocean and the Teno Mountains.

Trail in Buenavista del Norte with 18 sights
This pleasant circular route is 5.4 km long and more of a leisurely stroll. It takes about one and a half hours, but if you want to take great nature shots along the way and enjoy the breathtaking scenery, you will probably need two hours. The coastal trail through Buenavista del Norte is an interesting short trip into the past and presents an ideal opportunity to gain insight into the fascinating geology and natural history of Tenerife. We explain you the 18 most important natural and cultural sights of this self-guided trail.
Starting point of the trail: Buenavista del Norte
Aerial view of Buenavista del Norte at the foot of the Teno Natural Park
Buenavista del Norte is located in the northwesterly-most-point of Tenerife, between a mountainous area with lush vegetation and the rugged Atlantic coast. A peaceful village far away from the overcrowded tourist areas, where it is easy to get in contact with the locals and their traditions. Thanks to its remoteness, a rich cultural heritage within an original landscape have been preserved.
The green and white trail in Buenavista del Norte is signed with Playa Las Arenas. Starting point is just next to the tourist office in the town center, at the market square Plaza de los Remedios (1) with its church and the typical Canarian houses from the 16th century. All the buildings around the plaza consist of old masonry and tiled roofs. Two floors are arranged around a central courtyard, which gives access to the rooms and premises of the house via a wooden staircase. Sliding windows made of wood are typical, some of which are arranged asymmetrically. In 1983 the entire old town of Buenavista del Norte was declared a historical complex.
Enjoy the Canarian way of life
Market square (plaza) and Los Remedios church in Buenavista del Norte
Before you start the coastal trail through Buenavista del Norte, we recommend you a short coffee stop at the plaza. Beneath huge laurel trees you can sit relaxed and experience the local life of this beautiful Canarian village. The Canarios are warm, open-minded and communicative people. In addition to the natural beauty of Buenavista del Norte, the contagious serenity of its inhabitants contribute to making the village a very special place.
Do you know where the name Buenavista comes from? Stories tell that the Spanish conquerors were so impressed by its situation between the mountains and the ocean that they spontaneously gave it the name Buenavista, which means "beautiful sight".

Historic sites on the trail in Buenavista del Norte
Right behind the plaza you cross the Triana Gorge, a green oasis with barbecue places and the former wash houses Los Lavaderos (2). The building is rectangular and consists of fourteen stone wash basins, each of which with a water inlet and outlet. After this, you will pass partly abandoned, partly actively cultivated banana plantations. At the La Visitación chapel (3), the path branches off to the right on a small staircase, past the historic 16th-century building Hacienda de La Fuente (4), manor house and former residence of the founder of Buenavista, Juan Méndez.

On a narrow stony path you walk along the golf course of Buenavista del Norte towards the Atlantic.

Important crop in the Canary Islands: the banana
This idyllic part of the trail in Buenavista del Norte is lined with colourful bougainvillea, opuntias, agaves and aloe. You can see the nice tropical banana trees from the very proximity and without any disturbing fence (5). Did you know that around 140,000 tons of bananas are harvested every year in Tenerife? In short, more than 35,000 Canarios live from the cultivation of this delicious fruit and only about 10% are exported to other European countries.

After that, the coastal trail through Buenavista del Norte leads you above the Triana Gorge. At its mouth into the ocean you reach the viewpoint (mirador) Playa de Los Barqueros (6) with a small chapel. It is worth taking a detour down to the picturesque bay which was once the boat dock of the village. But be careful: signs warn of the risk of falling rocks. When the sea is calm you can swim or snorkel here, but bathing shoes are needed because of the slippery stones.
Former moorings of Buenavista del Norte: Playa de Los Barqueros
Basalt columns on the cliffs
On the opposite cliff of the bay you can see vertical basalt columns and even a stone daisy (7). These bizarre rock formations made of lava rocks are striking and geologically very interesting. Admire how nature created spectacular landscapes out of rocks reminiscent of the work of a sculptor! The cooling process of the lava is crucial for the formation of these basalt columns which always arise when the lava flow cools very slowly.

Green massif of the Teno Natural Park
Further, the coastal trail through Buenavista del Norte is paved with individual lava stones and meanders along the rugged rocky coast. Hardly anywhere else on Tenerife can you feel as close to the Atlantic. Roaring surf, smell of iodine in the air and sea birds in the sky are balm for the soul. Certainly, walking shoes with a rigid sole are the best choice for this path.
View from the trail in Buenavista del Norte of the rugged volcanic coast
Similarly, the bright green of the golf course designed by the famous Severiano Ballesteros forms an amazing color contrast to the dark lava landscape. In the distance, you see the mountains and deep gorges of the Teno Mountains (8), the oldest part of Tenerife, which was formed by volcanic eruptions about eight million years ago. On days of good visibility you can make great photos from Spain's highest mountain, the Teide volcano (3,718 m).

Moreover, this stretch of coast once played an important role in feeding the local population. Numerous concheros (parts of shells) lying on the golf course are evidence of this. After collecting the mussels, the guanches (Canarian natives) separated the shell from the edible part to make the goods easier for transport.
Isla Baja – a volcanic platform
Isla Baja stands for the lower island that lies at the foot of the Teno Mountains (9). It originated from recent volcanic eruptions near the coast, where lava masses spread out like a fan. The Buenavista mountain or Taco volcano played an important role in shaping the relief of this part of the island. It underwent different eruptions, both underwater and aerial, that formed the lower island where the town of Buenavista del Norte currently sits.

Likewise, further eruptions at more than 700 meters over sea level took place and lava streams flowed through the mountain gorges forming this extensive platform over 300,000 years ago. As a result, the former Teno cliffs have been pushed back from coast. The newly formed Isla Baja is composed of the villages of Buenavista del Norte, Los Silos, Garachico and El Tanque.

Salt pans on the coastal trail through Buenavista del Norte
In an extended left curve you can see on your right several flat holes in the rocks (lajas) that were used to extract salt in summer: the salt pans of La Tablada (10). The Atlantic floods the salt flats with water, crystals form on the surface and the finished product can be collected. To accelerate the evaporation process, the water was scooped by hand from the deeper holes. Certainly, salt was a valuable commodity for the inhabitants of Buenavista del Norte, not only for direct consumption, but above all for the preservation of fish. On the Canary Islands there were once 56 salt pans for the production of marine salt.
The white color of the salt pans (left) stands out against the lava and the blue of the sea
Lava ball
During your walk you will encounter a very interesting geological phenomenon, the so-called accretion ball or volcanic egg (11), a large lava stone that formed exactly like a snowball. As it rolled over the liquid lava flow from the higher El Palmar valley, it grew in size until it finally reached the coast of Buenavista del Norte where it solidified.
Lava ball originated from the valley of El Palmar
Plants on the coastal trail through Buenavista del Norte
Being the largest and highest island of the Canary Islands, Tenerife provides an impressive variety of plants. In just a few hundred meters, the vegetation changes radically, because different altitudes and microclimates create different vegetation zones or ecosystems. On your walk you will cross the following two of them.
Firstly, you will find the so-called coastal zone at approximately 50 meters above sea level. Salt-loving plants grow there, because they have adapted to the high salt content in the air (halophiles). Sea lettuce, sea parsley and sea fennel are typical plants. Secondly, appears the dry bush zone of about 50 to 400 meters with shrubby plants defying strong wind and sun. Typical shrubs from the spurge family are the tabaiba and the cactus-like Canary Island spurge or Cardón (12), both are endemic plants. If you want to learn more about the tabaiba plant, read our blog post "How we came up with the name Tabaiba Guesthouse".
Typical plant on the entire coastal trail through Buenavista del Norte: the Tabaiba
With its characteristic candelabra shape, the Cardón is one of the predominant plants in coastal vegetation
Typical trees and shrubs of the Buenavista del Norte coastline
Anyone who has ever travelled to the Caribbean also knows them: the sea grape or uva de playa (Coccoloba uvifera), an evergreen bush or small tree that also withstands salty sea air and near-desert conditions. Its ripe dark red fruits are edible and are sometimes processed into jam or fruit juice. On the short beach promenade at the end of the trail in Buenavista del Norte you can find particularly beautiful specimens.
Another typical plant is the Canary tarajal or taray (Tamarix canariensis), botanically also known as tamarisk. The dense shrub or small tree grows on coastal salt soils or in the lower part of the ravines. Deep roots keep it firmly anchored in the ground even during storms. Its bark contains tannin (a tannic acid) and coloring, which was formerly used for medicinal purposes. The Tarajal is a very robust plant that is able to adapt to changing and even difficult living conditions.

What to do at the end of the trail in Buenavista del Norte
Do some sport with sea view
The coastal trail through Buenavista del Norte ends at the heated public swimming pool (26 degrees Celsius) with gym and sauna (13). Athletic swimmers can swim in the 25 meter sports pool with seawater at any time of the year. Entrance is 4 euros per person. Open Monday to Friday from 10am to 10pm, Saturday from 10am to 2pm and closed on Sundays. The use of the sauna is by appointment and costs 3 euros per person (tel. 0034 922 12 81 01). To the right of the entrance, visitors are provided with some open-air exercise machines which can be used for free to train in the sun and with views of the Atlantic in front.
Try Canarian cuisine
Beach restaurant right next to the Atlantic
Just opposite the swimming pool there is a nice restaurant that specializes in fresh local fish and seafood. It has a large terrace from which you can enjoy a romantic sunset over the neighboring island of La Palma while listening to the sound of crashing waves. You can eat very well here or just enjoy a coffee or sundowner. Opens daily from 12 p.m. to 9 p.m. If you prefer an outdoor picnic, the coast of Buenavista del Norte is the perfect place.

Lava pools for a unique swimming experience
Swimming in the crystal clear waters of the Atlantic is always a pleasure, but the experience turns into something unforgettable when you swim in one of the natural pools of the Canary Islands. These charcos are huge puddles of sea water that were formed naturally between the lava stones. Because of the tides, they always fill with fresh water. Next to the beach, there are numerous charcos of different sizes where you can take a quiet bath protected from the waves (14). However, be careful when you get into the pools, because the lava is very slippery and sometimes sharp-edged.
Beach day in black volcanic sand
Sunset on Las Arenas beach with lava pools
The coastal trail through Buenavista del Norte ends at Playa Las Arenas (15). Although meaning "sandy beach", the sand on this beach varies with the seasons: only from May to November the tides bring the volcanic black sand on the shore. During these months, mainly locals spend their days off on this supervised beach, which is very popular with bodyboard surfers. Watch out for the strong currents and mostly very high waves! In winter, the tides carry the sand away and the bay turns into a wild stone beach. All year round, tis unique setting affords unforgettable sunsets.

Continue on the trail in Buenavista del Norte to a remote beach
If you want to keep on exploring the coast, you can hike some 500 meters more to El Fraile beach, an enchanting bay with strong waves and spectacular views. We do not recommend bathing on this lonely beach. The path to Playa El Fraile begins at the end of Las Arenas beach, at a picturesque stone-wooden bridge (16) behind the beach kiosk.
Way back to Buenavista del Norte
You can walk back either on the same coastal hiking path or along a little-used asphalt road. This starts about 20 meters in front of the beach restaurant at the roundabout (17) with parking space for campers, and continues uphill along the golf course to the Melià Hacienda del Conde hotel (18). In terms of architecture, the 5-star hotel is reminiscent of a magnificent palace. The spa belonging to the hotel offers a thermal circuit, a sauna and a Turkish bath. Massages can also be booked here by non-guests.
The way back to Buenavista del Norte with the Melià Hacienda del Conde hotel in the back left
At the end of the street, turn left and follow the cobblestone path down to the Hacienda del Conde mansion (4). After a few meters uphill, you will pass the La Visitación chapel (3) and shortly afterwards meet again on the signposted hiking trail to Buenavista del Norte.

Carlos Vergara Becomes President of the Big Apple Youth Soccer League
By Randy Vogt, Director of Public Relations, Eastern New York Youth Soccer Association
March 12, 2020-A seismic change has occurred in the Eastern New York Youth Soccer Association (ENYYSA). Luis Montoya founded the Big Apple Youth Soccer League (BAYSL) in 1997 to serve the growing Latino community in New York City and is the only President the BAYSL has ever known. That's changed as the torch has been passed to his right-hand man, Carlos Vergara, who has been elected the second President of the league.
ENYYSA President Richard Christiano stated, "We wish Carlos the best as he tries to fill the huge shoes of Luis Montoya and look forward to working closely with him."
They are distant relatives as Montoya is the uncle of Vergara's wife and both grew up in Peru. Both men are all about making sure that all children in New York have the opportunity to play the world's most popular sport.
Vergara played soccer in middle school and high school in the South American country. The Jamaica, Queens resident has volunteered for the BAYSL since 2003, starting as the Registrar.
The next year, he became a certified referee and the referee assignor for the BAYSL in 2010. Vergara has served as the BAYSL Games Chairperson for the past dozen years and also volunteered as the league Secretary.
He holds a US Soccer "D" Coaching License and started helping Montoya coach in the BAYSL Soccer Start Program a decade ago.
Vergara hopes to continue several initiatives started by Montoya, including a closer working relationship with the other mainly Latino league in New York City, the Metrokids Interregional Soccer League.
With approximately 100,000 youth soccer players––both boys and girls––and more than 25,000 volunteers, the non-profit Eastern New York Youth Soccer Association (ENYYSA) stretches from Montauk Point, Long Island to the Canadian border. Members are affiliated with nine leagues throughout the association, which covers the entire state of New York east of Route 81. ENYYSA exists to promote and enhance the game of soccer for children and teenagers between the ages of 5 and 19 years old, and to encourage the healthy development of youth players, coaches, referees and administrators. All levels of soccer are offered––from intramural, travel team and premier players as well as Children With Special Needs. No child who wants to play soccer is turned away. ENYYSA is a proud member of the United States Soccer Federation and United States Youth Soccer Association. For more information, please log on to http://www.enysoccer.com/, which receives nearly 300,000 hits annually from the growing soccer community.

On February 9, 2016, the Eighth Circuit Court of Appeals held that National Labor Relations Board (the "Board") properly concluded that an electrical subcontractor violated the National Labor Relations Act when it unilaterally changed its employee break policy without affording the employees' union an opportunity to bargain over the change. Parsons Electric, LLC v. NLRB, Nos. 14-3239 and 14-3662 (8th Cir. Feb. 9, 2016). This decision is a reminder for employers to consider whether a change in the terms and conditions of employment is sufficiently significant to require bargaining with a union before implementation.
Although the collective bargaining agreement between the employer and the union was silent on employee breaks, since at least 2005, the employer maintained a written employee break policy providing for a 15-minute break in the morning and a 15-minute break in the afternoon, subject to jobsite managerial discretion. In 2012, however, the employer amended its employee break by eliminating the default 15-minute breaks and stating that "[the employer] may establish specific break policies as part of the jobsite expectations." After a number of employees complained to the union that the employer ceased permitting afternoon breaks and early departures in lieu of breaks, the union filed an unfair labor practice charge.
To be sure, [the employer] retained discretion to override the two-break standard if the particular 'jobsite expectations' so required, but under the 2005 Break Policy, that discretion would be exercised as an exception to the default rule. The 2012 Break Policy, by contrast, eliminated the default rule with respect to employee breaks and instead granted [the employer] unfettered discretion to determine whether employee breaks would be permitted at all, and, if they were permitted, when they would occur and how long they would last.
In other words, while the 2005 break policy provided employees with a "specific, concrete standard," the 2012 break policy left the determination of breaks entirely to management.
The Eighth Circuit also rejected the employer's argument that the 2012 break policy was nothing more than a clarification of the company's standard practice under the former policy. Again deferring to the Board's findings, the Eight Circuit noted that "the Board credited evidence and testimony that, prior to 2012, the typical practice at [the employer's] jobsites was to follow the default standard set forth in the 2005 Break Policy." In the end, the court denied the employer's petition for review and granted the Board's petition for enforcement of its order.

Stacker raises $20M Series A to help business units build software without coding
Ron Miller 1 year
No-code platforms have developed into a hot market, and Stacker, a London-based no-code platform, is attempting to bring the concept to a new level. Not only can you create a web application from a spreadsheet, you can pull data from a variety of sources to create a sophisticated business application automatically (although some tweaking may be required).
Today the company announced a $20 million Series A led by Andreessen Horowitz, with participation from existing investors Initialized Capital, Y Combinator and Pentech. Today's investment brings the total raised to $23 million, according to Crunchbase data.
Michael Skelly, CEO and co-founder at Stacker, says that the idea is to take key business data and turn it into a useful app to help someone do their job more efficiently. "[We enable] people in business to create apps to help them in their working life — so things like customer portals, internal tools and things that take the data they're already using, often to run a process, and turn that into an app," Skelly explained.
"We really think that in order to actually be useful for business, you need to be hooked into the data that a business cares about. And so we let people bring their spreadsheets, SQL databases, Salesforce data, bring all the data that they use to run their business, and automatically turn it into an app," he said.
Once the company pulls that data in and creates an app, the user can begin to tweak how things look, but Stacker gives them a big head start toward creating something usable from the get-go, Skelly said.
Jennifer Li, a partner at lead investor Andreessen Horowitz, likes the startup's approach to no-code. "We've been watching the no-code space for a while, and Stacker stands apart from the rest because of its thoughtful product approach, allowing business operators to instantly generate a functional app that perfectly fits existing business processes," she said in a blog post announcing the funding round.
Five VCs discuss how no-code is going horizontal across the world's industries
The company currently has 19 employees, with plans to put the new capital to work to reach 30-40 by the end of the year. Skelly sees building a diverse company as a key goal and is proactive and thoughtful about finding ways to achieve that. In fact, he has identified three ways to approach diversity.
"Firstly is just making sure that we get a diverse pipeline of people. I really think that the ratio of the people you talk to is probably going to be the biggest indicator of the people you hire. Secondly we try to find ways we can hire people who are maybe further down their career profile, but [looking] to grow," he said.
Thirdly, and I think this is something that is not talked about enough, there are plenty of people who would like to get into programming roles, and who are underrepresented, and so we have members of our team who are converting from various non-technical roles to DevOps — and I think it's just like a really great route to add to the overall pool [of diverse candidates]," he said.
The company is remote-first, with Skelly in London and his co-founder Sam Davyson based in Geneva, and they intend to stay that way. They founded the company in 2017 and originally created a different product that was much more complex and required a lot of hand holding before eventually concluding that making it simple was the way to go. They released the first version of the current product at the end of 2019.
The company has a big vision to be the software development tool for business units. "We really think that in the future just like everyone's got email, a chat tool, a spreadsheet and a video conferencing tool nowadays, they will also have a software tool where they write and run the custom software that they run their business on," he said.

We started off with trying to figure out how to get to the Magic Kingdom (MK) from the Fort Wilderness Campground. As we left the campground there was a sign that said to turn RIGHT. So we did. When we got to a dead end, we had to turn RIGHT again because it was a one-way street. We could see the entrance to the Magic Kingdom parking on our left, but we couldn't GO LEFT! We continued on, looking for signs that said "Magic Kingdom" but we found none. We eventually got to an intersection where on the right, left, and center, it said Authorized vehicles only. We had to make a U-turn and figure out where we went wrong. We finally returned to the campground and took the boat to the Magic Kingdom.
When we asked one of the "cast" members how to get to the MK from the Fort Wilderness (FW) area, he said: "Turn right out of FW and follow the signs." We told him we did that but then he said, "Oh yeah, follow the sign that says 'Other guest services". Oh how obvious -- how did we miss that?

Day 2 of the adventure
We got to the Magic Kindom (MK) by boat, which was a very pleasant way to get there.
One of the first characters we saw was TIGGER! However, Grace was a little shy about the big tigger and mommy had to hold her.
Then we went on the carousel, and then off to Mickey's Toon Town Fair where we made Grace's week when we were able to meet CINDERELLA!!!!!! That is all Grace has been asking about since we arrived -- "Where is Cinderella? When are we going to see Cinderella???" (Over and over again.)
After that it was time for lunch in tomorrow land.
Then a good after-lunch type ride on "It's a Small World".
Then we used our FAST PASS at the Pooh ride. The Fast Pass really works! We got right on the ride with NO WAITING! It's too bad you can only use it one ride at a time. Grace LOVED this ride.
Then we went back to toon-town to catch the train back to Main Street. We caught it just in time and we were at the station on the second floor, just above the parade, and just in time to see Cinderella again. She leads the parade through the Magic Kingdom.
Grace was getting tired by this time (4:00pm) and we headed out to get our boat back to the Fort Wilderness Campground.
When we got there Grace had a great time on the playground equipment. There is a neat sliding board that is made out of the kind of rollers you see at the end of x-ray machines at airports for your baggage to slide easily. But she would only slide down with daddy. She also liked the "telephone". The telephone was really just a tube that went from one end of the playground to the other. It was about 4 feet off the ground and shaped like a megaphone at both ends. You could hear the person talking at the other end and of course you could talk to them. Grace sang the "I love you" song from Barney.
We had dinner planned for the Hoop-Dee-Doo Musical Revue and Grace really loved the beginning. Unfortunately, she fell asleep halfway through -- even though there was much hooping and dooing going on. We got her back to our cabin by walking and pushing the stroller on only it's back wheels so Grace would be in a prone position. She was still asleep when we got the cabin.
