I was the engineering officer in USS BURLEIGH (APA 95), a Maritime Commission C3-type vessel of 7,949 gross-tons that had been converted to a Navy attack troop transport. Following a voyage to Manila and Guiuan in the Philippines as part of operation MAGIC CARPET, BURLEIGH anchored in Virginia's Lynnhaven Roads awaiting decommissioning.
During the latter part of May 1946, the Army Transport Service sent a small team, including my recently hired brother Augie, to activate SS BELLE ISLE, a 1,900 gross-ton vessel that was delivered in 1932 by Swan, Hunter & Wigham Richardson of Newcastle, England. The team was ordered to steam BELLE ISLE to the Brooklyn Army Base.
Only a few months before BELLE ISLE was laid up in the nearby James River. Afterwards, planners realized that she was the only ship the Army had with shallow enough draft to transit a river for delivery of supplies to a base in Newfoundland. BELLE ISLE was towed to the shipyard in Newport News for activation. The only remaining problem was the lack of enough qualified people to sign on for the black gang. At dinner ashore one evening, I advised Augie that I could get a few days leave and would help with the short voyage to New York.
A buddy of my brother's was serving as the chief engineer and my brother was the first assistant. They both planned to stand watches so they needed just one more engineer. I also possessed a marine engineer's license, but I turned down the opportunity to sail as a ship's officer. I insisted on signing on as an oiler so that in the future, I could brag, "I once oiled a steam reciprocating engine."
A qualified engineer, someone from Belgium, was located and he took over as the third assistant.
BELLE ISLE's crew was still short one fireman so I returned to BURLEIGH and shanghaied one of my fireman, a clean-cut nineteen-year old from Wisconsin, by saying, "Come with me. We're going to ask the executive officer to give you a week's leave because I'm taking you to Brooklyn."
BELLE ISLE had some of the charm of Colin Glencannon's S.S. INCHCLIFFE CASTLE, a tramp steamer described by Guy Gilpatric in a series of humorous stories. BELLE ISLE's machinery plant provoked nostalgia because steam reciprocating engines were sources of great pride and because they were rapidly disappearing. Thus, the two-day voyage to New York was delightful. During night watches, I especially appreciated going aft once each hour to oil the steering engine and to take a moment to watch the phosphorous flashing in BELLE ISLE's wake.
After I signed off in New York, the 3rd assistant engineer said about me to my brother, "That was the best oiler I ever had."
My brother replied, "He should have been! Remember all those big Navy transports in Lynnhaven Roads? He is chief engineer in one of them."
The confused Belgian murmured something about crazy Americans.
I gave my engines the attention and love which I expected to get back from people. You've got to love engines if you're an engineer because you never knew when you were going to need them in an emergency. I could listen to them all day.

All the ordered maze of working parts were cleanly oiled and softly shining under the lights, and that was looksee pidgin, which told nothing about how well it would run, but a warm feeling went out from Holman to the engine and his hands lingered on the sculptured metal.
"Hello engine," he said softly.

Jayaraman, K. S. 2008. Entomologists stifled by Indian bureaucracy. Nature 452: 7.
An international collaboration to study insects in the Western Ghats mountains in southern India has been unable to get off the ground because of government concerns over biopiracy.
The story in a nutshell - an Indian entomology team working for an organisation called the Ashoka Trust for Research in Ecology and the Environment collected some 200,000 specimens for an ecological survey of the Western Ghats, but needed to send the specimens to experts in different countries to be identified (and potentially described if and when some turned out to be undescribed species) because India lacks the experienced persons to do so. However, sending specimens out of the country required that the Trust obtain a licence to do so from the governmental National Biodiversity Authority, and NBA says no.
"There is no restriction on collection or export of a few specimens for research.... But exporting 200,000 specimens is not permissible." The NBA encourages Indian scientists to send photographs or digital images to collaborators abroad instead of actual specimens, he says.
Unfortunately, this attitude shows complete ignorance of the requirements for research. Many invertebrates simply cannot be identified from external photographs along. Genitalia may need to be dissected out for many if not most insects. The news item does not mention if specimens of any groups other than insects are concerned, but many soft-bodied animals such as worms may require fixation on slides to examine internal anatomy. Experts on identification of a given invertebrate group will usually be few and far between, and it is quite believable that India (which does not have many well-funded research centres) lacks the expertise to identify many groups. This is especially true if costly techniques such as electron microscopy are required in identification, which are probably of limited availability in developing countries.
I also suspect, reading between the lines, that this might be a case of interference from the vertebrate-invertebrate divide, where policies that are developed with vertebrates in mind are unwisely applied to invertebrates. 200,000 specimens would be an extraordinary amount in a study on vertebrates, and would be quite rightly regarded as inordinate. One could also expect that most of the specimens would represent known species, and possibly could be identified from photos only. In a large-scale invertebrate survey, 200,000 specimens is surprisingly little, and one can feel certain that a significant proportion of those would represent undescribed species. The problem is especially acute when, as with many micro-invertebrates, the distinctiveness or otherwise of a given specimen can't be estimated prior to expert inspection.
And by essentially cutting off external input from better-funded countries (by making outside experts leap through too many hoops for it to be worth their time), the Indian government is effectively preventing its local researchers from improving their situation. For researchers in developing nations to improve their skill and knowledge base to the point where they don't need to seek outside assistance will almost certainly require a fair amount of initial input and training from said outside assistance. Also, as a significant amount of taxonomic work on Indian taxa has been conducted in other countries in the past, before principles of returning specimens to countries of origin were considered, many types and other critical specimens are held in non-Indian institutes. If Indian institutes are prevented from sharing their own specimens, then it forms a disincentive for non-Indian specimens to share specimens in turn, which could prevent Indian researchers from obtaining specimens critical to their own research.
It would be absolutely fantastic if Indian researchers were able to do all the required work on their own, without having to call in outside help. But to insist on such a state of affairs is to ignore the realities of current invertebrate taxonomic research, and to prevent conditions from ever improving. For shame!
There's currently a similar situation in Brazil... drives me nuts!


Plum's resident Chinese Astrologer, Narrye Caldwell, once again graces our site with her annual post on the upcoming New Year—this year's party is hosted by the Earth Pig.
The year of the Earth Pig arrives on February 5, 2019. If you're feeling a bit, well, dog-eared, after last year, I'm happy to tell you that the Pig Year will usher in a return to civility. Enough of this junk yard brawling and posturing with everyone's hackles up. The Pig is all about conviviality, grace, and harmony. So let's break this down.
First, there are always one or more elements to consider in every year. Last year (Earth Dog) was double Earth. The earth element can provide nourishment and stability. But too much, without any balancing influences, can cause stagnation and obstruction. That, combined with the Dog's uncompromising defensive attitude (read stubbornness) can create an environment of intractable hostility and anxiety. Witness the January stand off between Congress and the White House, the culmination of a year of this sort of thing.
With the upcoming Earth Pig Year, we have an Earth/Water combination. Water brings in the possibility of flow, movement, ease. In Chinese culture, water is a symbol of prosperity. It also signals the end of a cycle, a time when things dissolve and return to a state of incubation so that a new cycle can begin. Water can flow gently, or it can sweep you off your feet like a tidal wave. Much depends on other elemental influences. In this case, we have Earth combining with Water. Think of this like the banks of a river, or the land forms around a sparkling lake. Earth contains the water, gently guiding it along, so we benefit from flow and circulation, but are protected from torrential rain and floods.
Now, about that Pig. Pigs, like the water element, are at the end of a cycle. In this case, the 12 branch zodiac cycle. So the Pig is related to that auspicious moment when an old cycle is going to ground while a new cycle is being seeded. Now, don't expect the sudden appearance of a progressive and enlightened new age. This process takes time, and careful management of the qi. I'm going to take a risk here and predict that the dissolution of this current cycle of corruption and divisiveness will unfold over a period of 2-3 years. Yes, we'll see some welcome endings in 2019. But then in 2020 we'll need to show patience and attention to detail so the Rat can continue to incubate the seeds of change with careful data collection and analysis. Then we've got the Ox year in 2021 to put noses to the grindstone and do the required work to stabilize new foundations, before a courageous leap into a progressive new era can be launched with the Tiger qi in 2022. All I can say is, we better do things with scrupulous integrity over the next couple of years. But I'm getting ahead of myself.
Here's the good news for 2019. The Pig is associated with intelligence, wisdom, completion, fellowship, home, harmony, optimism, peace, sensitivity, and pleasure. Pigs are connoisseurs of fine dining and entertainment. Spending some time in the company of the Pig tends to remind us all of the refined intelligence and enlightened behavior humans are capable of. Once we've enjoyed the Pig's hospitality, we are likely to look back with embarrassed disbelief at the savagery, rudeness, and generally uncivilized behavior that has characterized the past year. We will all ruefully commit ourselves to a more civilized approach and, at the very least, a greater portion of hospitality towards all.
Since all of us will experience the year according to our own natures, it's important to reflect on how each of the animals might show up, as if coming to the Pig's home for a party. Tolerant, affable Pig always invites everyone; no one is excluded. So in keeping with this attitude of kindness and generosity, we should each arrive with a hostess gift in hand. See below for some tips on what each of the animals could, in the best case scenario, bring to the party.
Ox: You could use some time to recuperate from the Dog Year, during which you had to solve one problem after another. But you have much to contribute this year. Your steady, methodical approach will keep us on course, and turn the pleasures of human connection and compassion into real social progress. Your gift—remind us to keep a disciplined work ethic and a firm grip on our goals. Be the emblem of good order so we can rise to a higher level of social discourse.
Tiger: Yes, I know you're a frazzled wreck from having been on the field, going full tilt, during the entirety of the Dog Year. And though you would prefer to pad noiselessly into your cave and sleep for months, you can't in good conscience just disappear now. The Pig Year is actually a lucky time for you. You just need to moderate your activity to take full advantage of the rewards of your past efforts. This is a time to celebrate your accomplishments, raise a glass, bask in the sun, ease up and glow a little. Allow your muscles to relax, and please, cease that restless pacing. Your gift—you embody awesome deportment; show up and be yourself. Work less, play more. Lie around on the river bank. You will bring good luck to everyone at the party.
Rabbit: Finally, you can exhale. Being run ragged by the Dog has left you quivering with anxiety, and the Rooster Year that preceded that (2017) was even worse. But you made it, and now everything goes your way. The Pig is your great friend and can be relied upon to treat you with congenial good manners, and respect for your sensitivity. You will be put in charge of the seating arrangement at the Pig's gathering, an obvious perfect job for someone with your sense of diplomacy. Your gift—bring little origami cranes for each person at the party. You are an emblem of peace and contentment. With the friendly qi of the Pig Year acting like wind in your sails, you can come out of your burrow and spread peace and contentment everywhere you go.
Dragon: You are all about power, prosperity, passion, wisdom, and ambition. Your magic fell flat in the quarrelsome Dog Year, but now you can take flight again. In the Pig Year, everyone is delighted by your mythic visions. Your gift—enchant us with tales of the miraculous. Inspire us with bold visions of a beautiful future. We'll mostly be eating, playing board games, and studying philosophy this year, but when it's time (perhaps when you team up with Rat and Monkey in 2020), we'll be ready to follow you into that brilliant and promising future.
Snake: You're not a party goer, but try to understand the community need for conviviality and orderly social discourse this year. Sometimes people need a break from your relentless pursuit of profundity. One just cannot read Nietzsche all day every day. You are in opposition to Pig in the zodiac, and tend to see Pig's tolerance as gullibility. Then you can't help but get in there and disclose the dark underbelly of everyone and everything, just to see Pig go all gloomy. But Pig is inclusive and invites everyone, including you, to the party. Your gift—restraint. Smile appreciatively and use the time to deepen your own spiritual practice.
Horse: You share a sense of fun and sport with Pig. But like Tiger, you've been on the field all year and could use a rest. The Rat Year (2020), will be utterly confounding for you, so now would be a good time to return to the stable, munch on a well deserved bucket of oats, and enjoy a good rubdown. (Note: this means get regular body work or acupuncture to restore your physical prowess. Horses sometimes think of themselves as indestructible—a serious mistake). Your gift—though you're taking a year off, you can still show up to the party and bring your sense of adventure. Remind everyone to take a walk after dinner. Inspire them to take moderate exercise on a daily basis lest the good food and wine make them fat and sluggish.
Sheep: If anyone deserves a better year, it's certainly you. You've suffered through an entire year of being nagged, herded, and criticized. Your sensitivity, normally channeled into an uncanny knack for knowing what everyone around you needs, has devolved into frantic anxiety bordering on depression. But the Pig Year is one of your best years. You will be asked to organize and manage the party. Everyone listens to your expert advice. Your fine sense of management is called upon and succeeds brilliantly. That Dog that was snapping at your heals all year, goes loping off after a frisbee, completely forgetting about you. Your gift—polite but effective management, and an uncanny skill at arranging things so everyone gets to play and no one gets hurt. Bravo!
Rooster: There's not much that can distract you from your strict focus on long term goals. Not even the upcoming Pig Year party. However, remember this year's theme—a return to civility. You have, in the past, been accused of, ahem….a lack of sensitivity in your dealings with others. Well, ok, some people call it rudeness. Now, we know that you are actually a compassionate soul with deep feelings. This so-called rudeness is, in actuality, a clarity of focus that is not even graspable by most people. You can employ this skill in the Pig Year in an immensely helpful way. Your gift—keep us focused on long range planning. You can team up with your friend Ox in this endeavor. Remind people that the whole purpose of the party is to remember a time when people were kind to one another and respected differences. Our goal is not just to have some fun now, but to re-imagine, and bring into being, a just and enlightened society.
Dog: Actually 2018 wasn't the best of years for you. Being the sole guardian and protector of everyone and everything has left you exhausted. You won't need to be on guard duty again until 2022, the Year of the Tiger. So, curl up in front of the fire and get some much needed rest. Good boy. Oh right….you still have to show up to the party. Your gift—teach everyone how to nap.
Pig: Well, it's about time. Finally people are coming to their senses and realizing that nothing important happens in life until everyone has been properly fed. Social graces count. Friendship is necessary to health and happiness. As the 12th sign of the zodiac, and therefor the most sophisticated and wise, it is on you to teach everyone the fine art of being human again. Perhaps you could send us all the reading list in advance, so we'll be up to speed. The usual topics—philosophy, history, theology, mathematics, music appreciation—you know, the basic stuff that every human being should be able to discuss knowledgeably. Your gift—be the icon of civil discourse, friendship, tolerance, and good taste.

Thanks as always for this analysis! This Year of the Dog (even though I love dogs) can't end soon enough. Hopefully the Earth Pig will be kinder, and to all of us.
Oh, yeah, I'm so over the Dog Year!

Ex-foreign minister among top Tigray officials killed by Ethiopian forces
Members of the Ethiopian National Defense Forces walk along a road in Tigray -

By Rédaction Africanews
Ethiopia said Wednesday its forces had killed three prominent members of the Tigray People's Liberation Front (TPLF), whose leaders are the target of military operations in the country's northern Tigray region.
The dead included Seyoum Mesfin, who served as Ethiopia's foreign minister for nearly two decades, along with former federal affairs minister Abay Tsehaye and ex-parliamentary chief whip Asmelash Woldeselassie, according to a government statement.
The men died in "fire exchanges undertaken with the criminal clique's personal security" after "refusing to surrender," the statement said.
Prime Minister Abiy Ahmed ordered troops into Tigray in early November, a move he said came in response to TPLF-orchestrated attacks on federal army camps in the region.
Thousands have died in the fighting, according to the International Crisis Group, and tens of thousands of refugees have streamed across the border into Sudan.
Abiy declared victory in late November after federal forces entered the regional capital Mekele.
But the TPLF has vowed to fight on, and the UN reported last week that "localized fighting and insecurity continues" in several areas.
The TPLF's top leaders remain on the run, their whereabouts unknown.
In recent days the government has announced the capture of several TPLF officials, including Sebhat Nega, a founding member.
The TPLF dominated Ethiopia's ruling coalition for nearly three decades before Abiy came to power in 2018.

You Can't Make This Stuff Up! Cannabis Tales to Share…
Lori Malcolm June 6th, 2017 Leaf of the Week Share:
It's true, you can't make this stuff up! The cannabis culture is colorful and full of interesting facts and fallacies. Here are a few facts that may tickle your funny bone or leave you scratching your head in confusion.
Pot for Sale Online in 1971. The very first online purchase was an undisclosed amount of marijuana between students at two prestigious colleges. In the early 70's, long before eBay and Amazon, students at Stanford University using Arpanet accounts at Stanford University's Artificial Intelligence Laboratory, engaged in a commercial transaction with their buddies at Massachusetts Institute of Technology. The students used the school networks to complete the transaction.
More Pot Shops than Starbucks, What? We are accustomed to seeing a Starbucks on every corner, but not necessarily a pot shop. That dynamic has changed in Colorado and may soon sweep the nation. According to Google, at last count, there are approximately 700+ Colorado dispensaries, more than triple the number Starbucks (216) in the state.
The Colonist were forced to grow cannabis! The Jamestown colony in 1619 passed legislation which meant settlers were forced to grow cannabis. Hemp was a mainstream cash crop that was used to make rope, fabric and ship sails. It was literally against the law NOT to grow it.
What does beer and cannabis have in common? A terpene called Humulene naturally occurs in clove, basil, hops, and cannabis sativa. It conveys a subtle earthy, woody aroma with spicy herbal notes you might recognize in some of your favorite strains. While most cannabis strains increase appetite, humulene is known to suppress hunger.
Tupac, Up in Smoke! This one gets a little weird, but would you smoke the ashes of your deceased friend? Well, Tupac Shakur was cremated following his untimely death in 1996. A small family ceremony was held on the beach according to his friend and colleague from the Outlawz. "It's definitely true," Young Noble said. "We hit the beach and had a little memorial for him with his Moms and family and s**t. We was just givin' him our own farewell … We twisted up some of that great-granddaddy California kush and mixed the big homie with it, ya know what I mean?" Now you know.
Great minds think alike. The great astrophysicist and pop scientist, Carl Sagan was a serious stoner. In 1969, he wrote an article using the pseudo name of Mr. X that appeared in the 1971 book "Reconsidering Marijuana" but no one knew he wrote it until after his death. His words resonate with all of us: "The illegality of cannabis is outrageous, an impediment to full utilization of a drug which helps produce the serenity and insight, sensitivity and fellowship so desperately needed in this increasingly mad and dangerous world."
Nixon unknowingly smuggled weed for Louis Armstrong. In 1958, then Vice President Richard Nixon saw Louis Armstrong in an airport security line. Armstrong nervously sweating knew his bags would be confiscated because customs agents were tipped off about recent drug activity. Seeing it as a great photo opportunity with the famous Satchmo, Nixon went up to Armstrong and offered to carry his bags. Little did he know, Armstrong was packing about three pounds of pot in his suitcase. He took his suitcases without hesitation and brought them through customs and into America as a kind gesture to a friend. A traveling aide would later tell Nixon what happened, I bet he was pissed.
As always, cannabis products are designed for adult use only.
Peace, Love, and the Power of Cannabis!

Cooper called in to U20 Camp
PULLMAN, Wash. - After completing a historic inaugural campaign at Washington State, freshman Nadia Cooper will have a chance to show off her talents among the best the US has to offer as the young keeper was called in to training camp with the U.S. Under-20 Women's National Team. Cooper was one of 24 players to be called into the camp which runs Dec. 7-14 at the Elite Athlete Training Center in Chula Vista, Calif.. The U20 team is gearing up for the Concacaf U-20 Championships which will take place early in 2022 in teh Dominican Republic.
Cooper call into the U20 camp continues her ascent through the youth ranks of the U.S. system. She had previous been called up to the U17 National Team for multiple tournaments including in early 2020 for prep for the Concacaf U17 Championships that were later canceled due to the Covid-19 pandemic. During the lead up to the tournament, Cooper earned a start against England on Feb. 20, 2020 picking up a shutout in her last national team game before the pandemic.
This season as a freshman in the Crimson and Gray, Cooper showed off her elite talents becoming the first Coug in program history to not only be named the Pac-12 Freshman of the Year but also the conference's Goalkeeper of the Year. Additionally, Cooper was named both first team all-conference and all-region for her play between the posts. Her all-region selection marked the first time in program history a freshman had earned first team honors. On the year Cooper was one of the best in the nation in goal for the Cougs as she finished the year 10-1-3 between while tallying seven solo shutouts despite not taking over the starting job until Sept. 12. She would go on to set the Cougs' all-time record for consecutive shutout minutes with 523:56 minutes to begin her career, snapping all-time great Gurveen Clair's record set in 2013. In addition, Cooper became the first true freshman in program history to record shutouts in her first two career starts. In 15 appearances, Cooper allowed just 10 goals, finishing the season with a 0.617 goals against average, the third best average in program history for a Coug.

Q: How to detect events on a border of a div element [VUEJS]? I would like to detect events on a border of an div element in vue.js.
Is there a way? that could look like this:

The Solution that worked for my use-case:
borderHandler(event){
        var x = event.offsetX;
        var y = event.offsetY;
        if(
            (x < 0 || x > this.width)
            ||
            (y < 0 || y > this.height)
          )
        {
            alert("Border Pressed");
        }
    },

A: What you can do is try to calculate using some math and click event parameters if the mouse is inside the border.
Try clicking the borders in the example below, and you'll see this in actions by the element changing color, and logging some text below it.

Vue.component('my-component', {
    template: "#my-component",
    data() {
       return { messages: [], color: "red" }
    },
    methods: {
        handleClick(ev) {
           const x = ev.clientX;
           const y = ev.clientY;

AFRICOM Settling In For a Long Stay In Djibouti
Posted by xcroc under Africa command, AFRICOM, Botswana, CJTF-HOA, Ethiopia, Ghana, Kenya, nation building, proxy war, recolonize, security, Somalia, stability, Uganda
Camp Lemonier in Djibouti, seen from space, view it in Google Maps.
It looks like Camp Lemonier is on its way to becomming a permanent base. From the Stars and Stripes (you can see more photos in the article):
Camp Lemonier grows to support AFRICOM
… Increasing American activity in the Horn of Africa has propelled Lemonier from a sleepy 97-acre post to a 500-acre base that's become one of the military's major installations on the continent. Last year's stand-up of U.S. Africa Command means the base is only going to get busier.
"As AFRICOM matures, Camp Lemonier will transition to supporting long-term [theater security cooperation] efforts and establishing strong and enduring regional relationships," Gen. William "Kip" Ward, the AFRICOM commander, said during testimony to the House Armed Services Committee in March 2008. "Camp Lemonier will be a part of supporting and developing regional African capability and capacity; thus, its funding support must continue."
… Congress has set aside more than $100 million for camp improvements between fiscal 2007 and 2010 …
… the most telling indicators of the camp's larger role may be the new infrastructure that will allow it to serve as a support hub for Africa Command. Crews have already broken ground on new taxiways to increase its ability to manage aircraft. Leaders are considering putting in a "hot pad" that will allow planes to refuel, rearm and get back on their way quickly.
Lemonier is now set to be an enduring base of operations for Africa Command. Navy Capt. Patrick Gibbons, the base commander, envisions the camp as a forward staging base for troops making last minute preparations before a mission. It is already a logistics hub that supports ships working in the Gulf of Aden and aircraft flying counterpiracy missions there. Other teams are tasked to pick up anyone who needs to be rescued. Lemonier's mission even extends beyond the Horn of Africa region where Djibouti lies.
"The camp is becoming an enduring mission" …
Unfortunately, to date, and aside from the development photo ops in Djibouti, Camp Lemonier has contributed to destabilizing both Somalia, and Kenya, and facilitated the invasion and occupation of one country by another, the Ethiopian invasion and occupation of Somalia, and involved in planning and funding the disastrous raid on the Lord's Resistance Army by Uganda in December. These are all the actions of AFRICOM in East Africa. AFRICOM and Camp Lemonier contribute to propping up the dictator Meles in Ethiopia, as the US cozies up to Meles, funding his ambitions and excesses in the way that has discredited American good intentions and foreign policy around the world. It does not matter how real your politik, deeds tell the story. Mary Carlin Yates was just in Ethiopia planning further cooperation. The effect will be to destabilize, exploit, and oppress in Ethiopia and its neighbors:
March 25, 2009 (ENA) – Prime Minister Meles Zenawi on Wednesday received and held talks with US Africa Command Civilian Deputy (AFRICOM), Ambassador Mary Yates.
Ambassador Yates said as Ethiopia is AFRICOM's partner in security, the visit is intended to further scale up the relation.
Meles said Ethiopia and AFRICOM have been cooperating to ensure peace and security.
Accordingly, he said encouraging activities are being carried out in the area of military cooperation and capacity building.
The two parties have also discussed as to how to maintain the prevailing peace and security in Somalia, according to a senior government official who attended the discussion.
Of course step one to increase and maintain peace and security in Somalia would be to end Ethiopian involvement. There is nothing good Ethiopia can do in Somalia. It has no credibility. The history is so bad, that even if Ethiopians had good intentions, they would not be believed. That Ambassador Yates was discussing continued involvement in Somalia with Meles signals just how bad are US intentions, and how poorly informed is US planning.
AFRICOM is still looking for a permanent base in Africa. I doubt Camp Lemonier is seen as the permanent HQ, but it obviously is becoming permanent. Judging from a number of signals, including the very minor one, which parts of the archive of this blog are getting traffic, Ghana and Botswana are both under pressure and being seriously considered as potential home bases for AFRICOM. I surely hope Ghana can resist. The idea of hosting AFRICOM is not popular with any Ghanaians I know.
The US GAO, General Accounting Office, released a February report. From the New York Times
A report issued Wednesday by the Government Accountability Office acknowledged that the command had taken steps recently to win the trust of American diplomats and development experts, as well as African leaders. But it said the command must do a better job explaining what it does to build credibility among its United States government partners and with the African nations it is seeking to help.
"The military's large size brings the promise of increased resources," the report said, but that size also stirs concerns among African nations "about potential encroachment into civilian responsibilities like development and diplomacy."
In an interview here on Monday, before the G.A.O. issued its report, Gen. William E. Ward, the head of the command, said many of the misperceptions about the command had been dispelled.
If General Ward believes the "misperceptions", the products of realistic skepticism and knowledge of history, have been dispelled, he is living in a dream world. More likely he is continuing the same mistake AFRICOM planners have made all along, only listening to themselves, and those they have selected to agree with them.
The GAO report (PDF) on Africom makes clear that AFRICOM headquarters is still planned for the continent. It is one of the three main recommendations of the report:
• Include all appropriate audiences, encourage two-way communication, and ensure consistency of message related to AFRICOM's mission and goals as it develops and implements its communications strategy.
• Seek formal commitments from contributing agencies to provide personnel as part of the command's efforts to determine interagency personnel requirements, and develop alternative ways for AFRICOM to obtain interagency perspectives in the event that interagency personnel cannot be provided due to resource limitations.
• To determine the long-term fiscal investment for AFRICOM's infrastructure, we recommend the Secretary of Defense, in consultation with the Secretary of State, as appropriate, conduct an assessment of possible locations for AFRICOM's permanent headquarters and any supporting offices in Africa.
HTS Follies and AFRICOM
Posted by xcroc under Africa command, AFRICOM, Botswana, corruption, PMCs | Tags: HTS, human terrain system, McFate, Sarpone |
Montgomery McFate – lead social scientist for the US Army Human Terrain System
The Human Terrain system is supposed to provide information to the military on local people and local culture. I have written about it in relation to AFRICOM previously here: Human Terrain mired in a swamp.
HTS seems to be mired deeper than ever.
John Stanton describes:
Led by a wildly unpopular program manager (Steve Fondacaro) and a detached social science advisor (Mrs. Montgomery McFate Sapone), the HTS program continues to unravel. Program morale is at its lowest point in the short and controversial life of the program. Sources predict that more civilian HTT team members and soldiers will be killed/wounded because of lousy management practices and zero program oversight by upper echelon commanders/civilians. Secretary of Defense Robert Gates and General David Patreaus are also responsible for this dark state of affairs. In placing a recycled concept miles ahead of proper foundation and structure, they have compromised warfighters-in-theater, destroyed lives, and created a get-rich program for the most mercenary of HTS personnel and private contractors looking for lucrative employment.
… Mrs. McFate-Sapone reportedly nixes any dissent or critique of the HTS program. She has been described by HTS personnel as "a poisonous individual," "the crazy aunt in the room", and a "hustler". One said "you've got to watch your six with her."
Here are some quotes from people involved in the Human Terrain project:
"The HTS program is a ridiculous waste of tax payer money, and in the midst of a recession. Millions have been wasted. And the moronic management of the HTS program seems to have absolutely no problem placing poorly trained individuals in harm's way, going so far as to falsifying training documents."
"The amount of cash flying around the HTS program with very little oversight or accountability is disgusting. I continue to work for the HTS program out of obligation because I finish what I start, but trust me, I am counting down the days."
"I feel for the people whose careers are being ground up in this HTS program mess."
"It never ceases to amaze me how many egotistical individuals are involved with this HTS program."
The article points out:
It isn't really necessary to bring in academics to try to understand psychology, except perhaps for rare pathologies that are not likely to be encountered in everyday life [evolutionary psychology can speak to that]. Where HTS could have helped a lot is in understanding cultural norms and they did try to do that. But it seems to me that HTS over-promised when they claimed that they could help front-line tactical troops with specific situational awareness problems. The key thing to remember is that the differences between any two humans' behaviors will be greater than the differences in behaviors between cultures."
As someone who has moved between cultures a certain amount, I heartily endorse this last sentence.
Montgomery McFate, pictured above, is a major player in the fraud and failure. There is a great version of the picture of her here. And more about her domestic spying at Mother Jones.
More from journalist John Stanton on HTS:
Many academics/social scientists, according to one source, treat NCO's with disdain. Military personnel complain — legitimately — that they end up putting their lives at risk for non-combatant social scientists who offer human terrain system data that is rarely useful.
It is high time that civilian and military personnel in the Office of the Secretary of Defense and the US Army fix what in the minds of many has become a get-rich scheme for retired military contractors and their friends.
Sources indicate that HTS management has hired a consultant on Africa to sell the HTS program to AFRICOM (AFRICOM's new headquarters will apparently be in Botswana). And yet, according to a source, the program basics are not even settled. HTS program manager Steve Fondacaro "has spent $175,000 to procure 50 computers that remain unused." Another indicated that "No one is working! You can watch all the HTS personnel hanging out in the parking lot of the local hotel day after day waiting for something to do. And they get paid for that."
Interesting about AFRICOM HQ being located in Botswana. I have wondered about this. I have read other speculation on Botswana as the location. The current President of Botswana seems amiably disposed towards western militarism. So far I have seen nothing official.
Posted by xcroc under AFRICOM, Botswana, US military base
Maparangwane BDF (Air Wing) Base (from Google Earth Community)
circled above in yellow, closer up below, from Google Maps
 Botswana Defence Force Base, approximately 75km from the capital Gaborone. The main runway is astonishingly long for its intended use at 3360 metres. This has led to speculation over it's true role. Some people say it may serve as a landing and refuelling post for US spyplanes or as an alterante landing location for the space shuttle in the southern hemisphere given it's relatively close distance to the equator.
BAUMHOLDER, Germany – Jeffrey Morrison, the U.S. Army's 21st Theater Sustainment Command director of logistics (right), explains the process of loading vehicles onto rail cars to Botswanan officers (left to right) Captain Kabo Moswenyane, Lieutenant Gaopale Swereki and Major Ompatile Modisenyane, in Baumholder, Germany, on March 5, 2008. The purpose of the visit was to help the Botswanan officers learn about rail operations and bolster relations with the U.S. military. The Botswanan officers also received briefings on the military police, the Distribution Management Center and the use of American military jargon. They also traveled to other Army and Air Force installations in the area. (U.S. Army photo by Sergeant Phillip Valentine)
It is obvious from the photo and caption above, taken from africom.mil, that Botswana enjoys a close working relationship with the US military.
Botswana's one party democracy has long been a friend of the United States. Although Botswana has publicly questioned the creation of AFRICOM there have been ongoing rumors of agreements between the US and Botswana to host an AFRICOM base. That base may already be in place in the form of the Thebephatshwa Airport/Maparangwane BDF (Air Wing) Base. It is located about halfway between Molepolole and Letlhakeng, north and east of Gaborone. It is also referred to as Molepolole.
You can see it in this photo titled: A large US military base in the middle of Botswana. Taken enroute to WDH at FL350. Photo taken in 2003 by Julian Whitelaw. Click the link above to see the photo.
And Wikipedia has an interactive map of the base, info courtesy of b real, who adds:
where i found out about it was on an AFRICOM thread at the usmc's small wars council forum & military guys there say it was indeed built by the u.s. before apartheid ended in south africa.
From discussion at Google Earth Community, bbs.keyhole.com:
The base is called Maparangwane (that might be hard for you to get your tounge around). I have been there numerous times. It was probably (these things are usually kept secret) developed with the technical support of the USAF, but in all probability was funded entirely by Botswana's Government. We aren't exactly a poor country. If you use the ruler and go 71.37 Kilometres West south west (thats in between west and southwest) fom this airbase you will see the country's largest diamond mine at Jwaneng (marked by bright blue pools of some sort) – we have three. We are the 2nd largest producer of gem quality stones after Russia.
Anyways I sa with some probablity because it is possible that the ISAF have a sharing agreement with the government and might have footed some of the bill, but the country could easily afford to design and build such a thing.
The Eagle project. French influence, not US. Fighter, transport and chopper squadrons on base as well as a training squadron with PC-7 aircraft. The fighters are former canadian CF-5 A and B Freedom Fighters, which were sold to the BDF Air Arm after having been refurbished for the original 419 Squadron of the Canadian Armed Forces at CFB Cold Lake, Alberta Canada. After 419 was shut down in the mid 90s, they were sold and delivered via AN-124 air transport to the base were they were formed into 28 Squadron BDF AA. Transports are former USAF C-130 B versions, also refurbished. Choppers are 412s. Occasionally you might see a Global Express on the field. Botswana has spend considerable funds in the last 10 years on hardware from the Netherlands, Spain, France, Germany, UK, USA and Canada as well as from SA. Chinese technology and Indian expertise is present throughout the country. For such a small country they have accumulated an impressive arsenal. Although Thebe Phatswa (which is the actual base name) is the main air force base, the HQ is actually located just outside Gaborone and mostly Army. FOLs include Francistown and Maun. The foreign military in Botswana include mostly spec ops training elements from the UK US and a variety of african nations, not always with the knowledge of the BDF. Expats still run a large portion of tech intensive hardware and conduct training on various bases and in the field.
AFB Molepolole (USAF and BDF) 04/26/06 11:54 AM (google earth community)
The Botswana Defence Force Air Wing is the air force of Botswana.The Air Wing was formed in 1977 and is organisationally part of the Botswana Defence Force.All squadrons are designated with a Z, which has no meaning but is used as a designation for 'squadron'. The main base is Molepolole and was built mostly by foreign contractors from 1992 being finished around 1996.
this is the main Air base for Botswana'a Air Force. well actually that's pretentious. The Botswana Defence Force (the Army) has an Air wing, similar to what the UK had before wwII – as there isn't much need for a peaceful country to have a full air force.
From General Mompati S. Merafhe, the Botswana minister of foreign affairs and international cooperation, in October 2003, General Merafhe vigorously denies that it is an American airbase:
Regarding the alleged American airbase, let me state for the record that the United States does not own any military base in Botswana. The airbase that is being referred to is the Thebephatshwa Airbase that is wholly owned by the government of Botswana.
The airbase was constructed during my term as commander of the Botswana Defence Force with our own resources and without any assistance from the United States or any other country for that matter.
In fact, during construction, the Americans publicly accused Botswana of excessive military spending and threatened to cut economic aid to Botswana. So, if the Americans built the airbase, how could they then accuse us of excessive military spending on the airbase?
We have done our best to demonstrate that these allegations are false. Among other things, we have used every opportunity to conduct tours of the airbase for military dignitaries visiting Botswana, including military chiefs from the region. The purpose is to demonstrate to the region and indeed the international community that there is nothing sinister or clandestine about the airbase?
I have decided to raise this matter here because my government is seriously concerned about the damage this campaign of disinformation is doing to the image of Botswana in the region and internationally. Fortunately, we take solace in the fact that mud never sticks on a clean surface, it cakes and falls away.
From Scramble in the Netherlands comes this information about the Air Wing of the Botswana Defense Force.
The Botswana Defence Force Air Wing was formed in 1977 as a result of rising tension in the area. All squadrons are designated with a .Z., which has no meaning but is just used as a designation for .squadron.. Main base is Molepolole which was built mostly by foreign contractors from 1992 and was finished round 1996. Other bases used are the International Airport at Gaborone and Francistown.
The backbone of the Air Wing is formed by ex Canadian CF-116s which are locally designated as CF-5. Thirteen ex-Canadian CF-116s (ten single-seaters and three trainers) were ordered in 1996 to replace the Strikemasters, with another three single-seaters and two double-seaters delivered in 2000. For transport the Air Wing uses BN-2A/B, C212, CN235 and C-130Bs. Latest addition to the transport-fleet was an ex-AMARC C-130B to complement the two existing aircraft.
In 2000, three additional AS350BA helicopters were bought for Z21, bringing the total to eight.. The single Italian built AB412 has been replaced by an Bell 412EP in VIP-configuration. Z21 has a total of six Bell 412s of which the Bell412EP is being used by the VIP-Flight. Flying training is done on seven PC-7s. The VIP flight uses besides the Bell412 a Gulfstream and a Be200. In 1993 nine ex US Army/AMARC O-2As were delivered for use in the battle against poaching.
So what is actually going on between the US and Botwana. Your guess is as good as mine. But keep in mind these words from General Ward's Q&A for his confirmation hearing, PDF: U.S. Africa Command Will Enhance Local Skills, Problem Solving, again, courtesy of b real:
on basing criteria
Some of the criteria includes: political stability; security factors; access to regional and intercontinental transportation; availability of acceptable infrastructure; quality of life; proximity to the African Union and regional organizations; proximity to USG hubs; adequate Status of Forces Agreement (SOFA). The transition team has used these criteria to narrow down potential sites. Those potential sites have been briefed to the Dept of State informally and we have begun dialogue on the advantages and disadvantages of those sites.
Botswana meets these criteria. There was also a recent article in Air Force Times about two Air Force generals named to top spots in AFRICOM, which would fit in with air bases.
Brought up from the comments, courtesy of b real, and added April 9:
THE BOTSWANA DEFENCE FORCE: Evolution of a professional African military
. . . No discussion of politics or military affairs in Botswana can avoid a discussion of Seretse Khama Ian Khama. He is the most eminent member of what might be called the 'first family' of Botswana. His father, Sir Seretse Khama, was a national hero, prominent in the struggle for full national independence, and founder of the party that has governed the country since independence, serving as the country's president from its founding in 1966 until his death in office in 1980. When the Defence Force was created in 1977, Ian Khama was appointed its deputy commander with the rank of brigadier. Twelve years later, in 1989, he acceded to the command of the BDF with the rank of lieutenant general, a post he subsequently held for nine years. Khama's service spanned the formative period of the Defence Force's evolution, and despite his retirement in 1998 to enter politics, he continues to have a close connection with Botswana's military. Khama's current positions of vice-president and party chair of the ruling party are widely believed in Botswana to guarantee his accession to the presidency when the incumbent, Festus Mogae, steps down. However, Khama's activities over the course of his military and political career have provoked controversy and he is accused of having very authoritarian tendencies. Many among Botswana's educated elite view a future Khama presidency with some trepidation. . . .
From the US Dept. of State:
The United States has been the largest single contributor to the development of the BDF, and a large segment of its officer corps has received U.S. training.
. . . The United States considers Botswana an advocate of and a model for stability in Africa and has been a major partner in Botswana's development since its independence.
Botswana, military ties the main issue, not tribe includes the mention that "One knowledgeable [military] source estimated in 2004 that 75 per cent of BDF officers above the rank of major are graduates of US military schools."
the wikipedia entry on BDF says that "by 1999 approximately 85% of the BDF officers are said to have been trained under this system [IMET]."
It sounds very much as though Botswana is evolving away from democracy, and into a military government. And I am sure the US Department of Defense and AFRICOM are most happy and comfortable with Botswana's movement into militarism. This provides the US with a happy and willing "partner", well placed to act as a US surrogate on the African continent. And it puts the US Department of Defense and the Botswana government in the same business, speaking the same language. The less democracy, the more it becomes a military government, the more a few "boys in the back room" can make decisions without any pesky interference from legislatures, or the public at large. This further weakens what democracy is left. So the US can help "partner" away democratic institutions in Botswana.
This is a perfect illustration of why a military command cannot help foster democratic institutions, and economic development. The structure of a military command is a strict heirarchy organized to achieve military ends that require heirarchy and line of authority. In order to have political and economic development, a country must draw from a far wider pool for input, ideas, and investment, and defer to voices across a range of roles and ranks. It would certainly be nice if the US was investing as much money training people for other forms of public service, for all the skills that go into governing and delivering public services, water, sewars, electicity, roads, schools, clinics, hospitals, from local towns and municipalities to national governments, rather than building "defense" forces. The photo op "humanitarian" projects help, but they are no substitute for serious investment in developing civilian governing skills and institutions. Unfortunately, the current US governement does not believe in investing in these at home, and does not appear to believe in the actual practice of democracy.
What will happen if and when the citizens of Botswana become unhappy with losing their democracy to a military government? What role will the US play in that case?

Magigi
George da Soulchild aka Kaufela aka George Mukwita, co-host of our regular Sunday night radio show on Zambezi 107.7 fm, Livingstone's leading local radio station, writes about James Banda, Zambia's youngest music producer.
"Call him 'Jack Of All Trades', James Banda otherwise known as 'Magigi' is multi-talented in music circles and it leaves one wondering how he's mastered so much! The 16-year-old's ability to produce, write and sing songs puts him in a class of his own. Magigi, a grade nine dropout, has embraced music to raise money for school.
In an interview Magigi said he had to drop out of school due to lack of sponsorship. After his father stopped working last year life became difficult for James, but despite the problems he was facing, he qualified to grade 10 at Libala High School – though he wasn't able to take up the placement. Despite his considerable talent in music, Magigi is determined to go back to school, because for him, music goes well with education.
"I will surely go back to school because I cannot depend on music. Musicians get finished and so when things don't go well for me, I can easily fall back on my education," he said. Magigi urges upcoming musicians to prioritize education, stating that education is the only key to success. "Young musicians who don't have interest in education will regret it, because anything can happen in music. School is very important in life actually, it is education that can help somebody make it in life" he said.
Magigi, a music producer at Flat Line studios, has single handedly written and produced an eight-track album entitled, 'Certain Feelings', the songs are currently receiving massive airplay on local radio stations. The youngest musician in the country is currently scouting for sponsorship, so that he can release the album. "I have finished the album and hopefully soon it will be on the shelves, but I'm looking for sponsors to help me promote my music. Again, I need to find money to register my music with Zamcops. I don't have the licence yet to protect my music from piracy". Magigi said.
On how he has managed to fit in the industry at his age, he recounts that he has a rare touch to his music. "I have courage in the industry. I give respect to those I have found in music, but I don't fear them. I don't compete with anyone because I do musical things differently. I sing about the realities of life," Magigi noted.
He says through his music he speaks for the voiceless, especially the orphans and vulnerable children. "I speak for the people who are suffering in society. I teach people through music because I go to shanty compounds and see people are suffering. Sometimes I go on the streets to monitor street children. I thank God for giving me the talent," Magigi related. He says he's an open-minded person and always leaves room for criticism. "I like incorporating new ideas in my music. Even if I am young, I advise parents on various issues and due to the problems that I have passed through, I feel hurt whenever I am singing," Magigi said.
Born to Francis, a retiree, and Joyce Banda, a marketeer at Lusaka's Kamwala Clinic, Magigi is the last born in the family of five."

\section{Introduction}\label{Introduction}

Polarized beams are often considered as a research tool to
study the fundamental interactions and to search for new physics. Unlike spin-1/2 fermions, particles and nuclei with spin $s\ge1$ possess a tensor polarization.
This polarization is an important property of particles and nuclei and can be measured with a good accuracy. Investigations of dynamics of tensor polarization of light nuclei (e.g., the deuteron with spin 1) allow one to predict and to describe some new effects \cite{Bar3,Baryshevsky,PRC2007,PRC2008,PRC2009,JPhysConfSer,BarHE,TechPhysLett}. These effects are conditioned either by quadratic in spin interactions of deuteron \cite{Bar3,Baryshevsky,PRC2007,PRC2008,PRC2009,JPhysConfSer,BarHE} or by quantum beats in positronium \cite{TechPhysLett}. To get a basic understanding of polarization effects, it is necessary to consider \emph{linear} in spin interactions of \emph{tensor-polarized} particles and nuclei. The dynamics of the tensor polarization in external fields has been described in Refs. \cite{EvTensorPolnLee,JPhysG2015}. In Ref. \cite{EvTensorPolnLee}, some examples of evolution of the tensor polarization have been investigated and some properties of a $5\times5$ spin transfer matrix defining this polarization have been considered. Evidently, the use of the $5\times5$ matrix is much more difficult than that of the corresponding $2\times2$ matrix for the vector polarization.

In the present work, we use a simple general approach for a description of dynamics of the tensor polarization of particles and nuclei when this dynamics is caused by linear in spin interactions with external fields. The approach proposed allows one to couple dynamics of the tensor and vector polarizations and to obtain general formulas defining an evolution of particles/nuclei polarization in external fields. We also show that the spin tensor interactions result in mutual transformations of the vector and tensor polarizations and can influence the spin motion.

The square and curly brackets, $[\dots,\dots]$ and $\{\dots,\dots\}$, denote commutators and anticommutators, respectively.

\section{General properties of spin dynamics}\label{dynamics}

As is known, the spin
rotation is exhaustively described with the polarization
vector $\bm P$ defined by
\begin{eqnarray}
P_i =\frac{<S_i>}{s}, ~~~ i=x,y,z. \label{eq1P}\end{eqnarray}
Here $S_i$ are corresponding spin matrices and $s$ is the spin
quantum number. Averages of spin operators are expressed by their convolutions with the wave function
$\Psi(t)$. Particles with spin $s\geq1$ also possess a tensor
polarization. Main characteristics of such a polarization are
specified by the polarization tensor $P_{ij}$, which is given by
\begin{eqnarray}
P_{ij} = \frac{3 <S_iS_j + S_jS_i>-2s(s+1)\delta_{ij}}{2s(2s -
1)}, ~~~ i,j=x,y,z. \label{eqPRC}\end{eqnarray} The polarization
tensor satisfies the conditions $P_{ij}=P_{ji}$ and
$P_{xx}+P_{yy}+P_{zz}=0$ and therefore has five independent
components. In the general case, the polarization vector and the
polarization tensor are time-dependent. Additional tensors
composed of products of three or more spin matrices are needed
only for the exhaustive description of polarization of
particles/nuclei with spin $s\ge3/2$.

The eight parameters defined by the polarization vector and the polarization tensor are independent.  In
particular, $<S_iS_j>\neq <S_i><S_j>$.

The quantum-mechanical Hamiltonian describing the interaction of the spin with external fields contains
terms linear and bilinear on the spin:
\begin{equation} {\cal H}=\bm\Omega\cdot\bm S+Q_{jk}S_jS_k.
\label{VveEtot} \end{equation} Here $\bm S$ is the matrix operator
describing the rest-frame spin. Since the spin matrices satisfy
the commutation relation
\begin{equation} [S_i,S_j]=ie_{ijk}S_k ~~~ (i,j,k=x,y,z),
\label{commuta} \end{equation} the first term in Eq.
(\ref{VveEtot}) defines the spin rotation with the angular
velocity $\bm\Omega$. The absolute value and the direction of
$\bm\Omega$ may arbitrarily depend on time.

Even when the second term in Eq. (\ref{VveEtot}) is omitted,
dynamics of the polarization tensor is not trivial. We cannot
characterize the particle spin wave function only by a single
frequency. For a spin-1 particle, there are two frequencies,
$+\Omega$ and $-\Omega$, defining three equidistant levels. For a
particle with the integer spin $s=N$, there are $2N$ frequencies,
$\pm\Omega$, $\pm2\Omega$, ..., $\pm N\Omega$, defining $2N+1$
equidistant levels. The single frequency of the spin rotation,
$\Omega$, originates from the specific commutation relations
(\ref{commuta}) for the spin operators $S_i$. For a spin-1
particle, this property of the spin operators manifests in the
fact that $(S_i)_{13}=(S_i)_{31}=0~(i=x,y,z)$. Therefore, the spin
operators mix only two neighboring levels. But it is not the case
for the tensor polarization operators. Three of them mix the
levels 1 and 3 because the components $(S_{x}^2)_
{13},~(S_{x}^2)_{31},~(S_{y}^2)_{13},~(S_{y}^2)_{31},~(S_{x}S_{y}+S_{y}S_{x})_{13}$,
and $(S_{x}S_{y}+S_{y}S_{x})_{31}$ are nonzero. As a result, the
frequency $2\Omega$ also appears. For particles with greater spins
($s\ge1$), the situation is still more complicated.

We consider electromagnetic interactions, namely,
coupling of spins to electric and magnetic fields.
The second term in Eq. (\ref{VveEtot}) characterizes the tensor
electric and magnetic polarizabilities and the quadrupole
interaction. It influences dynamics of both the polarization
vector and the polarization tensor. As a rule, this term is much
less than the first one.
We can calculate the commutator $[{\cal H},S_i]$.
The term under consideration
brings a correction of the order of $|Q_{jk}S_jS_k|$ to the
angular frequency of spin precession $\Omega$. The effect of this correction on the spin dynamics is rather complicate
and does not reduce to a change of $\bm\Omega$. While the effect is small, it cannot be neglected in some cases (see Refs.
\cite{Bar3,Baryshevsky,PRC2007,PRC2008,PRC2009}). Nevertheless, its influence can be significant only in special cases like deuteron EDM experiments or experiments specially designed to measure the tensor magnetic and electric polarizabilities. In Secs. \ref{dynamics}--\ref{VerticalAxis}, we will disregard the spin tensor interactions and will take into account only the first term in the interaction Hamiltonian (\ref{VveEtot}).

The equation of spin rotation is given by
\begin{equation} \frac{d\bm S}{dt}=\frac i\hbar[{\cal H},\bm S]=\bm\Omega\times\bm S.
\label{VveEfft} \end{equation} When the particle/nucleus moves in electromagnetic fields, $\bm\Omega$ is defined by the Thomas-Bargmann-Michel-Telegdi (T-BMT) equation extended on the electric dipole moment (EDM) (see Refs. \cite{FukuyamaSilenko,PhysScr} and references therein):
\begin{equation} \begin{array} {c}
\bm \Omega=-\frac{e}{mc}\left[\left(G+\frac{1}{\gamma}\right){\bm B}-\frac{\gamma G}{\gamma+1}({\bm\beta}\cdot{\bm B}){\bm\beta}-\left(G+\frac{1}{\gamma+1}\right)\bm\beta\times{\bm E}\right.\\
+\left.\frac{\eta}{2}\left({\bm E}-\frac{\gamma}{\gamma+1}(\bm\beta\cdot{\bm E})\bm\beta+\bm\beta\times {\bm B}\right)\right].
\end{array} \label{Nelsonh} \end{equation}
Here $G=(g-2)/2,~g=2mc\mu/(e\hbar s),~\eta=2mcd/(e\hbar s),~\bm\beta={\bf v}/c$, $\gamma$ is the Lorentz factor, and $\mu$ and $d$ are the magnetic and electric dipole moments.

The Pauli matrices together with the unit matrix describe the spin of a Dirac particle and generate an
irreducible representation of the \emph{SU}(2) group.
Algebraically, the \emph{SU}(2) group is a double cover of the
three-dimensional rotation group \emph{SO}(3). As a result, the spin dynamics defined by the Dirac equation fully corresponds to the classical picture of rotation of an intrinsic angular momentum (spin) in external fields. The angular velocity of spin rotation does not depend on the spin quantum number. Therefore, both the classical description and the formalism
based on the Pauli matrices are applicable to particles/nuclei with an
arbitrary spin if the effect of spin rotation is analyzed.
Certainly, this formalism becomes insufficient if one considers spin-tensor effects mentioned in Sec. \ref{Introduction}.

In Eq. (\ref{Nelsonh}), the terms dependent on the EDM are presented. An experimental search for the deuteron EDM should take into account an existence of the spin tensor interactions  \cite{Bar3,Baryshevsky,PRC2007,PRC2008,PRC2009,JPhysConfSer}.

\section{Evolution of the polarization tensor}\label{vectorpol}

Let us first consider the approach used by Huang, Lee, and Ratner \cite{EvTensorPolnLee} to describe an evolution of the tensor polarization.
Instead of the polarization tensor (\ref{eqPRC}), the following spin-tensor operators can be used \cite{EvTensorPolnLee}:
\begin{equation} \begin{array} {c}
T_0=\frac{1}{\sqrt2}\left(3S_z^2-2\right), ~~~T_{\pm1}=\pm\frac{\sqrt3}{2}\left(S_\pm S_3+S_3S_\pm\right), ~~~ T_{\pm2}=\frac{\sqrt3}{2}S_\pm^2,
\end{array} \label{TensrPolnLee} \end{equation} where $S_{\pm} = S_1\pm iS_2$.
To obtain observable quantities, these operators should be averaged.

The approach proposed in Ref. \cite{EvTensorPolnLee} is based on the T-BMT equation, uses the Frenet-Serret curvilinear coordinates, and disregards the tensor interactions in the Hamiltonian (\ref{VveEtot}). Expressing the spin vector in terms of its components,
\begin{equation} \begin{array} {c}
\bm S=S_1 \bm e_1+S_2 \bm e_2+S_3 \bm e_3,
\end{array} \label{Lee} \end{equation}
one obtains the following equation of spin motion:
\begin{equation} \begin{array} {c}
\frac{dS_{\pm}}{d\phi}=\pm iG\gamma S_{\pm}\pm iF_\pm S_3, ~~~ \frac{dS_{3}}{d\phi}=\frac i2\left(F_- S_+- F_+ S_-\right),
\end{array} \label{Leet} \end{equation}
where $F_\pm$ characterize the spin
depolarization kick and $\phi$ is the azimuthal orbit rotation angle. The spin tune, $G\gamma$, is the number of spin revolutions per orbit turn.

Equations (\ref{TensrPolnLee})--(\ref{Leet}) allow one to obtain the set of five equations defining the evolution of the tensor polarization.  These equations can be presented in the matrix form with a 5$\times$5 matrix \cite{EvTensorPolnLee}. Evidently, the use of $5\times5$ matrices instead of standard $2\times2$ accelerator matrices needs much more cumbersome derivations. Moreover, even investigations of spin-tensor effects performed in Refs. \cite{PRC2007,PRC2008,PRC2009} used three-component wave functions and $3\times3$ matrices. Another remark is an absence of a direct connection between evolutions of the polarization vector and the polarization tensor, while spin tensor interactions are not taken into consideration in Ref. \cite{EvTensorPolnLee}.
We propose a different approach which couples dynamics of
the tensor and vector polarizations and simplifies a description of the evolution of the
tensor polarization of particles/nuclei in external fields.

It is not evident whether the evolution of the polarization tensor also reduces to the rotation. To clear the problem, we use the following approach. Let us consider the Cartesian coordinate system rotating about the $z$ axis with the same angular velocity $\bm\Omega(t)$ as the spin. In the general case, this angular velocity depends on time. We may superpose the rotating and nonrotating coordinate systems at the initial moment of time $t=0$ ($\bm e'_i(0)=\bm e_i$). The rotating coordinate system is denoted by primes.

The spin components in the rotating coordinate system remain unchanged:
\begin{equation} \frac{dS'_i}{dt}=0~~~(i=x,y,z).
\label{reunc} \end{equation}

As a result, all tensor polarization operators and all components of the polarization tensor are also unchanged in this coordinate system ($S'_iS'_j+S'_jS'_i=const,~P'_{ij}=const$). This important property shows that the tensor polarization of particles/nuclei with spin $s\ge1$ rotates in external fields similarly to the vector polarization. This is valid not only for electromagnetic interaction but also for other (weak, gravitational) interactions. Other products of the spin operators $S'_iS'_j\dots S'_k$ are also conserved in the rotating coordinate system.

To determine the particle polarization in the nonrotating coordinate system (lab frame), we need to connect the directions of basic vectors of the primed and unprimed coordinate systems. This problem can be easily solved. We choose the initial moment of time $t=0$. Evolution of any basic vector of the primed coordinate system coincides with that of the spin when it is initially directed along the considered basic vector. Therefore, the final directions of the three primed basic vectors are defined by the three final directions of the spin when its corresponding initial ones are parallel to the three Cartesian axes of the unprimed coordinate system.
As a result, dynamics of the polarization tensor reduces to that of the polarization vector. In particular, the evolution of the polarization tensor in accelerators and storage rings can be unambiguously defined with usual $2\times2$ spin transfer matrices. Thus, one need not apply much more cumbersome $5\times5$ matrices.

Time dependence of the polarization tensor defined in the lab frame can be easily expressed in terms of the basic vectors $\bm e'_i$.
Since $\bm e'_i(0)=\bm e_i$ and
\begin{eqnarray}
S'_i(t)=\sum_{k}{(\bm e'_i(t)\cdot\bm e_k)S_k},
\label{eqppnn}\end{eqnarray} the polarization tensor is given by
\begin{eqnarray}
P_{ij}(t) = \frac{3}{2s(2s - 1)}\sum_{k,l}{\left[(\bm e'_i(t)\cdot\bm e_k)(\bm e'_j(t)\cdot\bm e_l) <S_kS_l + S_lS_k>\right]}- \frac{s+1}{2s - 1}\delta_{ij}. \label{peqptfn}\end{eqnarray}

This simple equation defines general dynamics of the tensor polarization of particles and nuclei in
external fields.

\section{Spin rotation about the vertical axis}\label{VerticalAxis}

As an example, let us consider the simplest case when the angular velocity of the spin precession is constant and vertical ($\bm\Omega=\Omega\bm e_z$). We use the cylindrical coordinate system which is rather convenient for a description of spin dynamics in storage rings (see Refs. \cite{RPJSTAB,PhysPartNuclLett2015}). The spin motion in accelerators and storage rings is defined relative to either the momentum direction \cite{EvTensorPolnLee} or the horizontal axes of the cylindrical coordinate system.

When the beam is vector-polarized, the
direction of its initial polarization can be defined by the spherical angles
$\theta$ and $\psi$. In this case, $\theta=const$ and the azimuth $\psi$ rotates with the angular frequency $\Omega$ ($\psi=\psi_0+\Omega t$). We should mention that the angle $\psi$ is defined relative to the axes $\bm e_\rho$ and $\bm e_\phi$ but not relative to the axes $\bm e_x$ and $\bm e_y$. In particular, $\psi=0$ means that the spin is radially directed. In this case, the polarization vector and the polarization tensor are defined by (see, e.g., Refs. \cite{PRC2007,PRC2008,PRC2009})
\begin{equation}\begin{array}{c}
P_{\rho}(0)=\sin{\theta}\cos{\psi}, \qquad
P_{\phi}(0)=\sin{\theta}\sin{\psi}, \qquad P_{z}(0)=\cos{\theta}, \end{array} \label{eq4vc} \end{equation} \begin{equation}\begin{array}{c}
P_{\rho\rho}(0)=\frac32\sin^2{\theta}\cos^2{\psi}-\frac12,\quad
P_{\phi\phi}(0)=\frac32\sin^2{\theta}\sin^2{\psi}-\frac12,\quad
P_{zz}(0)=\frac32\cos^2{\theta}-\frac12,\\
P_{\rho\phi}(0)=\frac34\sin^2{\theta}\sin{(2\psi)},\quad
P_{\rho z}(0)=\frac34\sin{(2\theta)}\cos{\psi},\quad
P_{\phi z}(0)=\frac34\sin{(2\theta)}\sin{\psi}.
\end{array} \label{eq4tn} \end{equation}

When the direction of an initial \emph{tensor} polarization of a tensor-polarized beam obtained by mixing two incoherent beams with opposite vector polarizations is defined by the spherical angles $\theta$ and $\psi$,
$\bm P=0$ and the components of the polarization tensor are the same.

For spin-1 particles and nuclei, it is also convenient to consider the tensor-polarized beam with the zero
projection of the spin onto the preferential direction defined by the spherical angles $\theta$ and $\psi$. In this case,
$\bm P=0$ and the tensor polarization is given by
\begin{equation}\begin{array}{c}
P_{\rho\rho}(0)=1-3\sin^2{\theta}\cos^2{\psi}, \quad
P_{\phi\phi}(0)=1-3\sin^2{\theta}\sin^2{\psi}, \quad
P_{zz}(0)=1-3\cos^2{\theta}, \\
P_{\rho\phi}(0)=-\frac32\sin^2{\theta}\sin{(2\psi)}, \quad P_{\rho z}(0)=-\frac32\sin{(2\theta)}\cos{\psi}, \quad P_{\phi
z}(0)=-\frac32\sin{(2\theta)}\sin{\psi}.
\end{array}\label{intvi}
\end{equation}

\section{Spin evolution conditioned by the tensor interactions}

It has been ascertained in Refs. \cite{Bar3,Baryshevsky,PRC2007,PRC2008,PRC2009,JPhysConfSer} that the tensor interactions lead to mutual transformations between the vector and tensor polarizations. We can show that this property is general.
An analysis can be made on the basis of spin-1 particle matrices. As is known, main properties of spin
dynamics are common for particles with any spins. To consider the spin dynamics, we need to use basic properties of the spin matrices defined by Eq. (\ref{commuta}) and (for spin-1 particles) by the equation
\begin{equation}\begin{array}{c}
S_iS_jS_k+S_kS_jS_i=\delta_{ij}S_k+\delta_{jk}S_i.
\end{array}\label{intvi}
\end{equation}

These properties result in the following commutation relations:
\begin{equation}\begin{array}{c}
[S_\rho^2,S_\phi]=i\{S_\rho,S_z\},\quad [S_\rho^2,S_z]=-i\{S_\rho,S_\phi\},\quad
[S_\phi^2,S_\rho]=-i\{S_\phi,S_z\},\\ \,
[S^2_\phi,S_z]=i\{S_\rho,S_\phi\}, \quad
[\{S_\rho,S_\phi\},S_\rho]=-i\{S_\rho,S_z\},\quad [\{S_\rho,S_z\},S_\rho]=i\{S_\rho,S_y\},\\ \,
[\{S_\phi,S_z\},S_\rho]=2i(S^2_\phi-S^2_z),\quad [\{S_\rho,S_\phi\},S_z]=2i(S^2_\rho-S^2_\phi),\\ \,
[\{S_\phi,S_z\},S_\rho]=2i(S^2_\phi-S^2_z),
\end{array}\label{eqone}\end{equation}
\begin{equation}\begin{array}{c}
 [\{S_\rho, S_\phi\},S_\rho^2]=-iS_z,\quad
[\{S_\rho,S_z\},S_\rho^2]=iS_\phi,\\ \, [\{S_\phi,S_z\},S_\rho^2]=0,\quad
[S_\rho^2,S_\phi^2]=[S_\rho^2,S_z^2]=[S_\phi^2,S_z^2]=0.
\end{array}\label{eqtwo}\end{equation}
Other commutation relations can be obtained from Eqs. (\ref{eqone}) and (\ref{eqtwo}) by cyclic permutations of indices.

Now, unlike Eq. (\ref{VveEfft}), we take into account the tensor interactions in the term $(i/\hbar)[{\cal H},\bm S]$. Equations
(\ref{eqone}) and (\ref{eqtwo}) show that these interactions transform the vector polarization to the tensor one and the other way round, respectively. The both equations demonstrate that the tensor interactions do not lead to an additional rotation of the vector and tensor polarizations.

Nevertheless, a \emph{seeming} change of the angular velocity of the spin rotation can take place. Any vector-polarized beam is also tensor-polarized. The part of the operator $d\bm S/(dt)$ conditioned by the tensor interactions also changes the pseudovector $\bm S$. This effect can be mistaken for the above-mentioned change of $\bm\Omega$. The effect is rather important for the deuteron EDM experiment (see Refs. \cite{Bar3,Baryshevsky,PRC2007,PRC2008,PRC2009,JPhysConfSer}).
Thus, the tensor interactions can influence the spin motion.
