In this paper, we study the relativistic effect on the wave functions for a bouncing particle in a gravitational field. Motivated by the equivalence principle, we investigate the Klein-Gordon and Dirac equations in Rindler coordinates with the boundary conditions mimicking a uniformly accelerated mirror in Minkowski space. In the nonrelativistic limit, all these models in the comoving frame reduce to the familiar eigenvalue problem for the Schrödinger equation with a fixed floor in a linear gravitational potential, as expected. We find that the transition frequency between two energy levels of a bouncing Dirac particle is greater than the counterpart of a Klein-Gordon particle, while both are greater than their nonrelativistic limit. The different corrections to eigen-energies of particles of different nature are associated with the different behaviors of their wave functions around the mirror boundary.

Mineralocorticoid Receptors and Glucocorticoid Receptors in HPA Stress Responses During Coping and Adaptation
Edo Ronald de Kloet and Marian Joëls
The glucocorticoid hormones cortisol and corticosterone coordinate circadian events and are master regulators of the stress response. These actions of the glucocorticoids are mediated by mineralocorticoid receptors (NR3C2, or MRs) and glucocorticoid receptors (NR3C1, or GRs). MRs bind the natural glucocorticoids cortisol and corticosterone with a 10-fold higher affinity than GRs. The glucocorticoids are inactivated only in the nucleus tractus solitarii (NTS), rendering the NTS-localized MRs aldosterone-selective and involved in regulation of salt appetite. Everywhere else in the brain MRs are glucocorticoid-preferring. MR and GR are transcription factors involved in gene regulation but recently were also found to mediate rapid non-genomic actions. Genomic MRs, with a predominant localization in limbic circuits, are important for the threshold and sensitivity of the stress response system. Non-genomic MRs promote appraisal processes, memory retrieval, and selection of coping style. Activation of GRs makes energy substrates available and dampens initial defense reactions. In the brain, GR activation enhances appetitive- and fear-motivated behavior and promotes memory storage of the selected coping style in preparation of the future. Thus, MRs and GRs complement each other in glucocorticoid control of the initiation and termination of the stress response, suggesting that the balance in MR- and GR-mediated actions is crucial for homeostasis and health.
Developmental Neurobiology of Anxiety and Related Disorders
Emily M. Cohodes and Dylan G. Gee
The majority of anxiety disorders emerge during childhood and adolescence, a developmental period characterized by dynamic changes in frontolimbic circuitry. Frontolimbic circuitry plays a key role in fear learning and has been a focus of recent efforts to understand the neurobiological correlates of anxiety disorders across development. Although less is known about the neurobiological underpinnings of anxiety disorders in youth than in adults, studies of pediatric anxiety have revealed alterations in both the structure and function of frontolimbic circuitry. The amygdala, prefrontal cortex (PFC), anterior cingulate cortex (ACC), and hippocampus contribute to fear conditioning and extinction, and interactions between these regions have been implicated in anxiety during development. Specifically, children and adolescents with anxiety disorders show altered amygdala volumes and exhibit heightened amygdala activation in response to neutral and fearful stimuli, with the magnitude of signal change in amygdala reactivity corresponding to the severity of symptomatology. Abnormalities in the PFC and ACC and their connections with the amygdala may reflect weakened top-down control or compensatory efforts to regulate heightened amygdala reactivity associated with anxiety. Taken together, alterations in frontolimbic connectivity are likely to play a central role in the etiology and maintenance of anxiety disorders. Future studies should aim to translate the emerging understanding of the neurobiological bases of pediatric anxiety disorders to optimize clinical interventions for youth.
Xenacoelomorpha Nervous Systems
Pedro Martínez, Volker Hartenstein, and Simon G. Sprecher
The emergence and diversification of bilateral animals are among the most important transitions in the history of life on our planet. A proper understanding of the evolutionary process will derive from answering such key questions as, how did complex body plans arise in evolutionary time, and how are complex body plans "encoded" in the genome? the first step is focusing on the earliest stages in bilaterian evolution, probing the most elusive organization of the genomes and microscopic anatomy in basally branching taxa, which are currently assembled in a clade named Xenacoelomorpha. This enigmatic phylum is composed of three major taxa: acoel flatworms, nemertodermatids, and xenoturbellids. Interestingly, the constituent species of this clade have an enormously varied set of morphologies; not just the obvious external features but also their tissues present a high degree of constructional variation. This interesting diversity of morphologies (a clear example being the nervous system, with animals showing different degrees of compaction) provides a unique system in which to address outstanding questions regarding the parallel evolution of genomes and the many morphological characters encoded by them. A systematic exploration of the anatomy of members of these three taxa, employing immunohistochemistry, in situ hybridization, and high-throughput transmission electron microscopy, will provide the reference framework necessary to understand the changing roles of genes and gene networks during the evolution of xenacoelomorph morphologies and, in particular, of their nervous systems.
Insect Navigation: Neural Basis to Behavior
Stanley Heinze
Navigation is the ability of animals to move through their environment in a planned manner. Different from directed but reflex-driven movements, it involves the comparison of the animal's current heading with its intended heading (i.e., the goal direction). When the two angles don't match, a compensatory steering movement must be initiated. This basic scenario can be described as an elementary navigational decision. Many elementary decisions chained together in specific ways form a coherent navigational strategy. With respect to navigational goals, there are four main forms of navigation: explorative navigation (exploring the environment for food, mates, shelter, etc.); homing (returning to a nest); straight-line orientation (getting away from a central place in a straight line); and long-distance migration (seasonal long-range movements to a location such as an overwintering place). The homing behavior of ants and bees has been examined in the most detail. These insects use several strategies to return to their nest after foraging, including path integration, route following, and, potentially, even exploit internal maps. Independent of the strategy used, insects can use global sensory information (e.g., skylight cues), local cues (e.g., visual panorama), and idiothetic (i.e., internal, self-generated) cues to obtain information about their current and intended headings. How are these processes controlled by the insect brain? While many unanswered questions remain, much progress has been made in recent years in understanding the neural basis of insect navigation. Neural pathways encoding polarized light information (a global navigational cue) target a brain region called the central complex, which is also involved in movement control and steering. Being thus placed at the interface of sensory information processing and motor control, this region has received much attention recently and emerged as the navigational "heart" of the insect brain. It houses an ordered array of head-direction cells that use a wide range of sensory information to encode the current heading of the animal. At the same time, it receives information about the movement speed of the animal and thus is suited to compute the home vector for path integration. With the help of neurons following highly stereotypical projection patterns, the central complex theoretically can perform the comparison of current and intended heading that underlies most navigation processes. Examining the detailed neural circuits responsible for head-direction coding, intended heading representation, and steering initiation in this brain area will likely lead to a solid understanding of the neural basis of insect navigation in the years to come.
Neuroendocrine and Neuroimmune Mechanisms Regulating the Blood-Brain Barrier
Divine C. Nwafor, Allison L. Brichacek, Sreeparna Chakraborty, Catheryne A. Gambill, Stanley A. Benkovic, and Candice M. Brown
The blood-brain barrier (BBB) is a dynamic structural interface between the brain and periphery that plays a critical function in maintaining cerebral homeostasis. Over the past two decades, technological advances have improved our understanding of the neuroimmune and neuroendocrine mechanisms that regulate a healthy BBB. The combination of biological sex, sex steroids, age, coupled with innate and adaptive immune components orchestrates the crosstalk between the BBB and the periphery. Likewise, the BBB also serves as a nexus within the hypothalamic-pituitary-adrenal (HPA) and gut-brain-microbiota axes. Compromised BBB integrity permits the entry of bioactive molecules, immune cells, microbes, and other components that migrate into the brain parenchyma and compromise neuronal function. A paramount understanding of the mechanisms that determine the bidirectional crosstalk between the BBB and immune and endocrine pathways has become increasingly important for implementation of therapeutic strategies to treat a number of neurological disorders that are significantly impacted by the BBB. Examples of these disorders include multiple sclerosis, Alzheimer's disease, stroke, epilepsy, and traumatic brain injury.
Achieving Adaptive Plasticity in the Spinal Cord
James W. Grau
The traditional view of central nervous system function presumed that learning is the province of the brain. From this perspective, the spinal cord functions primarily as a conduit for incoming/outgoing neural impulses, capable of organizing simple reflexes but incapable of learning. Research has challenged this view, demonstrating that neurons within the spinal cord, isolated from the brain by means of a spinal cut (transection), can encode environmental relations and that this experience can have a lasting effect on function. The exploration of this issue has been informed by work in the learning literature that establishes the behavioral criteria and work within the pain literature that has shed light on the underlying neurobiological mechanisms. Studies have shown that spinal systems can exhibit single stimulus learning (habituation and sensitization) and are sensitive to both stimulus–stimulus (Pavlovian) and response–outcome (instrumental) relations. Regular environmental relations can both bring about an alteration in the performance of a spinally mediated response and impact the capacity to learn in future situations. The latter represents a form of behavioral metaplasticity. At the neurobiological level, neurons within the central gray matter of the spinal cord induce lasting alterations by engaging the NMDA receptor and signal pathways implicated in brain-dependent learning and memory. Of particular clinical importance, uncontrollable/unpredictable pain (nociceptive) input can induce a form of neural over-excitation within the dorsal horn (central sensitization) that impairs adaptive learning. Pain input after a contusion injury can increase tissue loss and undermines long-term recovery.
Deep Neural Networks in Computational Neuroscience
Tim C. Kietzmann, Patrick McClure, and Nikolaus Kriegeskorte
The goal of computational neuroscience is to find mechanistic explanations of how the nervous system processes information to give rise to cognitive function and behavior. At the heart of the field are its models, that is, mathematical and computational descriptions of the system being studied, which map sensory stimuli to neural responses and/or neural to behavioral responses. These models range from simple to complex. Recently, deep neural networks (DNNs) have come to dominate several domains of artificial intelligence (AI). As the term "neural network" suggests, these models are inspired by biological brains. However, current DNNs neglect many details of biological neural networks. These simplifications contribute to their computational efficiency, enabling them to perform complex feats of intelligence, ranging from perceptual (e.g., visual object and auditory speech recognition) to cognitive tasks (e.g., machine translation), and on to motor control (e.g., playing computer games or controlling a robot arm). In addition to their ability to model complex intelligent behaviors, DNNs excel at predicting neural responses to novel sensory stimuli with accuracies well beyond any other currently available model type. DNNs can have millions of parameters, which are required to capture the domain knowledge needed for successful task performance. Contrary to the intuition that this renders them into impenetrable black boxes, the computational properties of the network units are the result of four directly manipulable elements: input statistics, network structure, functional objective, and learning algorithm. With full access to the activity and connectivity of all units, advanced visualization techniques, and analytic tools to map network representations to neural data, DNNs represent a powerful framework for building task-performing models and will drive substantial insights in computational neuroscience.

Consumer Groups Complain to CRTC Over Koodo's Lack of Monthly Paper Billing
by Gary Ng – Thu, June 14, 2018
The option for a monthly wireless paper bill is still very important to some people, especially Koodo Mobile customers. However, Koodo no longer offers monthly paper bills, as the company only offers digital documents.
This raised the ire of some, which led consumer advocacy groups, the Public Interest Advocacy Centre (PIAC), and the National Pensioners Federation (NPF), to file complaints to the CRTC last week over the issue.
According to 77-year-old Janette Little-Gallian from Berwick, Nova Scotia, paper wireless bills are her preferred choice. "I'm sure the majority of old people like myself prefer to get that monthly [paper] statement. Most of us don't do a whole lot online," she told CBC News.
Trish McAuliffe, interim president of the NPF—which represents over one million seniors and retirees nationwide—says "it's their right," when it comes to paper bills.
The concern is whether Koodo's parent company, Telus, will follow suit and eliminate monthly paper bills. "They just quietly try to do it one at a time, and then the next thing you know, no one's getting paper billing," said McAuliffe.
But according to Koodo, the shift to e-bills is related to "advancements in digital adoption" and "ongoing efforts to support the environment," said a Telus spokesperson to the CBC.
Telus said they are committed to accessible services and visually impaired customers do have an option for bills written in braille.
Back in 2014, the federal government eliminated paper billing fees. However, despite this new legislation, Koodo argued recently the company is not obligated to provide paper bills, according to the company's online forum moderators.
According to PIAC executive director John Lawford, he says Koodo is defying the law, telling CBC News in an interview, "Why was it put there? Well, because Parliament wanted people to get paper bills — with no charge."
He continued to say "Perhaps some day there will be an all [electronic] service, but I think it's only fair to customers to give them what they want until they fully make that transition."
Currently, Rogers, Fido, Bell, Virgin and Telus all still offer paper billing—except for the latter's flanker brand, Koodo.
Canadians can submit their comment on the PIAC/NPF filing with the CRTC here.

Fendi, Prada, Dior: the ladies of fashion explain luxury
A high fashion that knows how to return to classic. How? By practicing sustainability, away from hypocrisy. And who can do politics. Fashion ladies explain luxury today. Silvia Venturini Fendi, Miuccia Prada and Maria Grazia Chiuri (Dior) present the way of the top of the range in contemporary society to the press.
The ladies of fashion explain luxury
In an era of great contamination with sportswear, for example, there is a sense of elegance to be found (and therefore taught). Silvia Venturini Fendi, designer of the homonymous brand controlled by LVMH group (in the photo on the left) is sure of it: "Classic is timeless – she says to Milan Finanza Fashion -. We have to re-educate young people to the classic, because this represents a form of sustainability".
True sustainability
Speaking of sustainability, again with MFF Miuccia Prada (in the photo, in the centre) can recognise that, today, finally, it really is a practice. "While sustainability was previously a theory – she says -, now I have to say that it is really happening. With us it has become normal". When it comes to fashion responsibility, however, easy moralisms must be avoided. "At the beginning, I was a bit unpleasant about the hypocrisy on this argument – she continues -. For example, the other day we had this blouse with a missile. Then it was said God, no, not a missile! And then in the meantime the world kills itself, but the missile toy doesn't".
Everything is political
On the other hand, if everything is political in life (as the adage says), luxury cannot be locked in its niche, as if what happens outside does not interest them. "I believe that in this historical moment we cannot fail to reflect on certain topics – these are the words of Maria Grazia Chiuri from MFF (in the photo, right) -. I started with feminism, which includes other themes for me, it does not simply talk about women. Mine is an activist fashion, I always say it". The designer's skill, therefore, lies in modulating her message in a manner consistent with the identity of the brand she works for. "At first, it was viewed with suspicion, criticised, but I believe that anything you do in life has a political value – concludes the designer -. When I arrived, they kept telling me that Dior was tied to the idea of the founder's silhouette. Nobody ever thinks about it, but Christian Dior founded the company after the Second World War, in a devastated Paris. He thought of that silhouette in a very precise historical context. For me, the idea that that represented femininity nowadays manifested a fundamental problem. Perhaps that was the reason that led me to talk about certain problems".

Conditions For Use Of The NOAA Weather Radio All Hazards Logo
NOTE: The NOAA All Hazards Logo/Trademark is intended for specific use on NOAA All Hazards Weather Receivers as well as websites and community outreach that support and advocates the use of NOAA All Hazards Radio. If your needs are more general for supporting and advocating the mission of NOAA and/or the National Weather Service, please visit the website https://www.weather.gov/logorequest to request permission to use the NOAA and/or National Weather Service official trademarks.
NOAA's Weather Radio (NWR) program is one of the many NWS operational program offices. NOAA Weather Radio is an integral operational entity of every NWS forecast office.
The name, NOAA Weather Radio All Hazards, represents radio receivers that are capable of receiving weather and/or warning information from NWS Forecast Offices, approved Department of Homeland Security offices responsible for the dissemination of warning information, and those Emergency Operation Centers that have been specifically authorized to disseminate warnings on the NWR operational frequencies. To be called a NOAA Weather Radio All Hazards receiver, the device must possess specific receiver requirements contained in CTA-2009-B.
NWR provides 24 hour broadcasts of local weather information and warnings of severe weather specific to each of its broadcast locations. The NWR program also has the distinction of providing warning information for any and ALL HAZARDS that may affect the communities served by local NWR broadcasts, as well as warnings that are disseminated on a state and/or national level. The scope of the all hazard warnings includes both natural and man-made situations that would mandate notification and/or advisories to citizens in the broadcast area. State and national warnings also include terrorist activity and/or situations of civil unrest. The warning situations mentioned herein are not all inclusive but go to defining the scope of the warning responsibilities of NWR.
The first step in the approval process is testing the receiver to ensure it meets the requirements in CTA-2009-B. It must be noted that the NWR program office is not a testing facility, nor is it a certification laboratory. Any receiver testing must be accomplished by an independent test or certification facility. The second step in the approval process is an operational evaluation. This will be done by the NOAA Weather Radio Program Office/Office of Dissemination Branch personnel. Receivers should be submitted to the Dissemination Branch of the NWR program office for operational evaluation by NWR program office staff and/or engineers prior to authorization for use of the NWR All Hazards logo. (Receivers submitted for evaluation may not be returned.)
The NOAA Weather Radio All Hazards logo, pictured above, is a graphic with the words "All Hazards" printed in the color red above the acronym "NOAA". NOAA is printed in the color blue featuring all capital letters and the front leg on the letter "N" is elongated and shaped in the form of a lightning bolt, and the second letter "A" is elongated with a red dot at the apex of the letter "A" and three concentric circles emanating from the dot (in the color red). Centered below the acronym "NOAA" is the product name, "Weather Radio" printed in blue. Centered below the product name, "Weather Radio", is the agency name, "NOAA's National Weather Service" which is over-lined and underlined with a horizontal line, all in the color blue. The Registered Trade Mark symbol, ®, will immediately follow and be on the same plane and color as the bottom horizontal line. The logo is set onto a white background.
The official colors for NOAA Weather Radio All Hazards logo are:
Pantone 200 CVU (red)
Pantone Reflex blue.
The logo is set into a white background.
Procedures for requesting use of the All Hazards NOAA Weather Radio logo
A. Use of the NWR logo must be specifically authorized in writing by the NOAA Weather Radio (NWR) Program Office. Requests for authorization to use the NOAA Weather Radio All Hazards logo should be submitted to the NWR Program Office on the Application for Use of NWR Image. The application is also available on the NWR web site at Request for Use of NWR Logo.pdf.
B. Before an application for use of the NOAA Weather Radio All Hazards logo can be approved for use on weather radio receivers or devices containing weather radio receiver modules, the person or organization requesting use of the logo must perform the following steps. NWR receivers with either Specific Area Message Encoding (SAME) or 1050 Hertz tone alerting capability are eligible to apply for use of the NWR logo. NWR receivers which do not include either of these alerting capabilities are not eligible for NWR logo use.
1) The requester shall submit an application for NWR logo use to the NWR Program Office. Applications can be submitted by e-mail to nws.nwr.logorequest@noaa.gov or by regular mail to the following address:
National Weather Service Headquarters
1325 East-West Highway (Room 5346)
(Attn: NWR Program Office - Weather Radio Evaluation).
2) The NWR Program Office uses the CTA-2009-B "Performance Requirements for Public Alert Receivers" document as a guideline in the evaluation of NWR receiver performance for NWR All Hazards logo use. Requesters are also required to submit CTA-2009-B testing results to the NWR Program Office, along with their logo application. The following documents provide further definition on the specific types of CTA-2009-B test data the NWR Program Office requires for SAME alerting and Tone (1050 Hz) alerting NWR receivers:
SAME Alert Receivers - CTA-2009-B Test Data Requirements
Tone Alert Receivers - CTA-2009-B Test Data Requirements
3) The requester is also required to submit a minimum of two production representative samples of the NWR receivers, along with users manuals, to the NWR Program Office for further review, including a basic reliability evaluation, feature and function evaluation, and a determination of user friendliness, all from a consumer's perspective. Receivers submitted for evaluation to ITS and NWS will not be returned.
4) When the NWR Program Office completes its review of the receivers, the requester will be contacted and advised if NWR logo usage will be authorized for the receiver.
Receivers that meet the minimum standards during the NWS evaluation will be recommended for use of the logo. Camera-ready artwork of the logo will accompany a letter to the requester indicating the conditions for usage of the logo. Receivers that do not meet minimum requirements will cause a letter to be sent to the requester indicating use of the logo is not authorized and the basis of that decision.
Any claims by consumers against the receiver, to include operational characteristics, quality, standards, and/or features must be addressed by the manufacturer. NWR and the National Weather Service will not hold harmless any receiver manufacturer for the operations or features of their product.
C. Applications for use of the NOAA Weather Radio All Hazards logo are model specific. A separate application must be submitted for each model of receiver being evaluated. If a weather radio receiver is authorized to display the NOAA Weather Radio All Hazards logo and that receiver is subsequently modified, updated, or enhanced, then a new application must be submitted, along with two samples of the modified receiver and updated CTA-2009-B testing results.
Once a brand and model weather band receiver has been authorized to use the NOAA Weather Radio All Hazards logo, thereby classifying it as a NOAA Weather Radio All Hazards receiver, subsequent distribution by a commercial re-seller does not alter the classification as a NWR All Hazards receiver, provided that the receiver has not been altered.
D. The size and color of the logo may be changed to contrast with equipment or packaging background colors. However, the logo design must not be altered in any way. The NOAA Weather Radio All Hazards logo may not be used with or in conjunction with any phrase, slogan, comment, endorsement, advertisement, or promotion, unless specifically authorized in writing by the Director of NOAA National Weather Service.
CTA STANDARDS (CTA-2009-B). To be classified as a NOAA Weather Radio All Hazards receiver, the receiver must meet, at a minimum, stringent requirements as specified in the Consumer Technology Association (CTA) Standard 2009-B (or current revision), Performance Specification for Public Alert Receivers. SAME capable receivers are required to meet all CTA-2009-B requirements while receivers which alert using the 1050 Hertz tone are required to meet all the CTA-2009-B requirements, with the exception of section 5, which is only pertinent for SAME capable receivers. Visit CTA at www.CTA.tech.
There is a difference in the logos used for weather alert receivers. The three logos depicted at the end of this bulletin represent the current logos approved for NOAA Weather Radio Receivers. Each of the logos is different in their definition and the organization sponsoring them. Each logo depicted may, upon receipt of written authorization from the respective controlling organization, be displayed alone or in combination with any of the other logos. It is important to know that each of the logos depicted, in addition to being sponsored by different organizations, are referred to by different names. The NOAA logo, represented by the letters "NOAA" above the sea waves in the circle is a registered trade mark of the U.S. Department of Commerce. The NOAA Weather Radio All Hazards logo, represented by the words "All Hazards" above the letters "NOAA", is a registered trade mark of the National Weather Service. The National Weather Service is an agency of the U.S. Department of Commerce. The Public Alert logo, represented by the words "Public Alert", is a registered trade mark of the Consumer Electronics Association. Each organization may only authorize use of its respective logo.
Each of the logos discussed require adherence to the specifications contained in CTA-2009-B, and written authorization for use after licensing requirements have been satisfied.
Compliance with all sections of CTA-2009-B would classify a weather band receiver as a Public Alert receiver. Public Alert receivers are authorized to display the Public Alert logo, after official certification and adherence to licensing requirements from CTA. A weather band receiver may display both the NOAA Weather Radio All Hazards and the Public Alert logos, if logo requirements from both NOAA's National Weather Service and CTA are met.
Only weather band receivers that meet all the requirements of CTA-2009-B, display the CTA Public Alert logo, and have received specific written authorization from the National Oceanic and Atmospheric Administration of the Department of Commerce, are authorized to display the NOAA logo.

What Is the Best Way to Polish Rosewood?

How to Stain & Oil a Desk
Rosewood is a hardwood used on the fretboard of stringed instruments. It is prized by musicians for the way it feels and the mellow tone that it imparts to the instrument. Rosewood has a slightly oily feeling that stays that way for the life of the instrument. It is a medium to dark brown color with distinguishing black grain lines.
Penetrating Oils
Rosewood is rarely coated or sealed with top coats such as lacquer or varnish. Penetrating oils are typically used to promote the soft feel that musicians prefer. Penetrating oils allow the wood to breathe and stay pliable, feeding the wood what it needs to maintain its active feel -- as if the wood were still alive. If the instrument neck begins to dry out, you can add more penetrating oil at any time. Lemon oil is one of the preferred oils used on rosewood, with linseed oil typically second choice.
Rosewood doesn't need much polishing. By the time it is installed on the necks of instruments, it has already been sanded to a fine polished surface, much finer than typical woodworking projects. The applications of oils to the neck with a cotton cloth simply maintain the existing polished surface. Lightly rubbing the wood until it looks wet is usually enough to bring luster back to the wood. If the luster doesn't come back after one application, some light polishing can be done, but it's rarely needed.
If you do need to get aggressive to bring the luster back to the rosewood, it's best to polish parallel with the grain direction. Often, rosewood instrument necks have limited open space, so working between frets or under strings is common. Usually, musicians polish rosewood when they change strings on the instrument. Penetrating oils do not harm strings, but they can deaden them if excessive amounts of oils are used. After the neck is wet, polish vigorously with the tip of a finger wrapped in a dry cotton cloth. A rotary tool with a soft polishing wheel accessory also works well for this task. Just be gentle and polish at a low speed if the rotary tool has a variable speed dial. When the wet oil is removed, the neck has been sufficiently treated.
The most common polish for rosewood is everyday furniture polish. The compounds found in furniture polish are similar to the natural oils that already exist in the pores of rosewood. Furniture polish formulas that contain lemon oil are the preferred choices for polishing rosewood, but most over-the-counter polishes work equally as well. Furniture polish also cleans and can remove discolored or smudged areas from the wood. Furniture polish also imparts a nice smell to the wood, which can be quite pleasant when playing an instrument that has a neck made of rosewood.

Most bloggers talk about current events; I, on the other hand, like to discuss movies that are ten to sixty years old. That's how I make sure I'm not saying the same thing as everyone else. I talk about the outdated stuff.
At any rate, the husband and I watched the movie The Boondock Saints last night, and it got me thinking about vigilantism. Many of our modern heroes are actually vigilantes: Batman, Spiderman, Jack Bauer, Dexter. They right the wrongs that slip through our justice system.
But, I mean, why are there so many wrongs to right?
I re-read last night Bill Whittle's section of Responsibility dealing with prairie justice. He's right that if you read that section to someone from 1880's America, they wouldn't get it.
The idea of punishing the property owner while rewarding the thief would so violate their common sense, their keenly developed sense of responsibility, that they simply could not believe what they were hearing, and that is because for those people, cold, hard reality stalked them right outside their front door, and moronic inversions of cause and effect would quite simply get you killed. That's why it was called common sense…it was the Minimum Daily Requirement of intelligence and logic that one needed to survive on a daily basis. Those who didn't have it were too stupid to live, and had been eaten by wolves or prairie dogs, depending on just how stupid they were.
Reality has receded far from the front porch in modern America, and in those isolated towers of law offices, bureaucracies and faculty lounges, all manners of thought inversions can grow and prosper. I recently heard of a woman who sued a car dealership. It seems her son had stolen a car from said dealership, gone on a joy ride -– drunk, of course -– and gotten himself killed. The woman claimed that if the dealership had maintained adequate security, her son would not have been able to steal the car and he'd be alive today.
What has happened in the last 100 years that has made us, as Whittle puts it, lose sight of "the difference between perpetrator and victim"? How did we get from Jack McCall to OJ Simpson?
We watch these vigilantes on TV and we cheer them on for doing the job that our police and courts cannot do. But isn't there something inherently awful about that? Why do criminals slip so easily through the cracks?
I think the best part of The Boondock Saints was the very end where they interview folks on the street for a documentary about the making of the movie (here on YouTube, at 2:30). The opinions were split on whether the brothers' vigilantism was moral or immoral. That end segment made the movie.
Prairie justice was harsh, but I'm not sure we're always better off these days. Sometimes I just want Dexter to go chop up some bad guys.
I don't think we're better of nowadays in regards to this AT ALL.
I don't find Ellie Nesler an ideal mother in most respects, but I sure did feel like cheering for her when she killed her son's molester.
Perhaps if we were allowed to really defend ourselves nowadays, I would feel fine letting my kids go to the park without me watching over their shoulder. As it is, I feel like I have to hover. Because God forbid anything happen to them, it will be about the "poor" perpetrator who was driven to what s/he did by a horrible childhood.
"But, I mean, why are there so many wrongs to right? ... We watch these vigilantes on TV and we cheer them on for doing the job that our police and courts cannot do. But isn't there something inherently awful about that?"
If Gotham City needs Batman, what does that say about Commissioner Gordon's police force?
A fourth: Is there a correlation between vigilante fantasy entertainment and an increasingly criminal-coddling society? (The rise of the Death Wish movies after the 60s might indicate that the answer is yes.) I don't think there was anything 'cool' about frontier justice 'back in the day'; it was a harsh fact of life. But nowadays such justice has turned into escapism and the reality is that people want to deny responsibility. People have always wanted to deny responsibility, but it's never been easier.


Three attractive dances which are great fun to play.
They may be performed by 2 equal saxs, or alto sax with tenor playing from the additional transposed 2nd part. This could also apply to Eb and Bb clarinets playing together.
Three short movements arranged for three (or more) clarinets, or mixed woodwind instruments. Multiple parts can be supplied to order.

Warrant – Louder, Harder, Faster
Frontiers Music srl
Review by Dawn "The Metal Priestess" King
As I have mentioned in previous reviews, I feel I was born too late where the rock and metal scene is concerned, many of my favourite bands being at the top of their game when I was too young to really appreciate them. This has meant that over the years there have been many bands that have passed me by and Warrant is one of them. Only really knowing their cheesy hit "Cherry Pie" through endless airplay on MTV and radio stations, I never really had much desire to check them out.
And what a mistake that was! With eight million records sold worldwide, two top ten Billboard albums, five top forty Billboard hits and five number one MTV videos, Warrant had the peak of their popularity at the end of the 1980's and beginning of the 1990's, forming part of the glam rock scene (another reason I am surprised they didn't have that much effect on me to start with as I love that particular genre of metal!)
Formed in the mid 80's by Erik Turner and Jerry Dixon, they released their classic debut album "Dirty Rotten Filthy Stinking Rich" in 1989 and, with extensive touring, sales exceeded two million records in the US alone!
1990 saw the release of their second album "Cherry Pie" and, produced by Beau Hill (Alice Cooper, Winger, Europe and Ratt) it featured hits "I Saw Red" and the anthem "Cherry Pie" which received massive airplay on MTV and still does to this day, making it probably their most well-known hit.
In 2008, their lead singer and songwriter Jani Lane quit the band and he was replaced by ex-Lynch Mob vocalist Robert Mason. Often referred to as one of the most prolific songwriters of the 1980's, Lane died in 2011 from acute alcohol poisoning.
The band kept going and in 2011 released "Rockaholic" the first to feature Mason on vocals and the album that relaunched them as a force to be reckoned with in the 21st century.
Now, six years later, "Louder Harder Faster" has been released with a line-up of original members and is proving that Warrant are now stronger than ever!! With the production handled by Foreigner and ex-Dokken bass player Jeff Pilson, Warrant are sounding tighter and are playing better than ever and "Louder Harder Faster" remains true to the bands roots, full of rocking songs with some classic ballads thrown in.
Warrant have always had a catchy, very melodic style and that remains their signature sound even now, although they did experiment with a more grunge orientated album in the mid 1990's to acknowledge the growing popularity of that genre.
Mason's vocals are still a breath of fresh air and it is clear he was the best choice as a replacement for Lane. He has a swagger about him that gives new life to the band who are now "fired up and more inspired than ever musically."
Stand out songs for me were "Music Man", which starts off acoustically before crashing into a blues-filled rock song, title track "Harder Louder Faster" which sets the tone for the rest of the album from the outset and "New Rebellion" and of course, there is the customary rock ballad in "U In My Life."
The thing I love most about the glam rock genre is the ability of the songs to make you dance around your living room like a complete nutter!! And this album certainly made me do that. Even sitting here, listening to it on my headphones, I am bopping away as I type. It is a real feel good album and one more suited to the summer. I can just imagine driving down the motorway, roof down (if my car had the ability to do that!) with the sun shining and this blasting from the speakers!
I just have one question now for the boys?……..when are you coming to play London because I will be first one there.
Classic Warrant, classic glam rock, excellent music!

NASCAR Pinty's Series
NCATS: Ranger By a Nose at St-Eustache
Series Release/Photo by Matthew Manor, Getty Images for NASCAR
Edges Dilley In Thrilling Canadian Tire Series Finish
ST-EUSTACHE, Que. (July 25, 2015) – Andrew Ranger edged Mark Dilley in a green-white-checkered flag finish to gain a record 20th career victory in NASCAR Canadian Tire Series presented by Mobil 1 action Saturday at Autodrome St-Eustache.
Dilley led the field in the race's final restart, and the two jockeyed throughout the ensuing two laps before Ranger powered to victory from the outside and just thwarted Dilley's charge from the inside to the finish line.
The Lucas Oil National 250 presented by Lacroix Tuning propelled the Roxton Pond, Quebec, native to sole possession of the series' all-time lead. He was previously tied with D.J. Kennington at 19.
Marc-Antoine Camirand crossed the line third with L.P. Dumoulin fourth and Kennington fifth. Alex Tagliani, Gary Klutt, J.F. Dumoulin, Anthony Simone and Scott Steckly rounded out the top 10.
Steckly started on the pole and led the majority of the event, but fell off the pace late with a broken axel and was fortunate to salvage a top-10 finish. His lead on Jason Hathaway in the championship standings actually grew to 11 points as Hathaway finished 15th, the result of a mid-race accident.
Saturday's Lucas Oil National 250 telecast will premiere on TSN on Aug. 1 at 6:30 p.m., and on RDS2 on Aug. 15 at 2:30 p.m.
The Canadian Tire Series will return to Quebec next week for the Grand Prix de Trois-Rivieres on Aug. 2.
