Diurnal rhythm in British Antarctic personnel

first_imgIntroduction: The diurnal rhythm of saliva cortisol and its association to adaptation, performance and health were examined in personnel over-wintering at two British Antarctic stations. Methods: In total, 55 healthy individuals (49 males, 6 females) participated in the study. Cortisol in saliva was sampled on 3 consecutive days (at awakening, 15 and 45 min after waking, at 15.00 h, and 22.00 h) immediately after arrival at the station, midwinter, and the last week before departure. Subjective health complaints were also measured at arrival, midwinter, and the last week before departure, while depression (Burnam screen for depression) and positive and negative affect (PANAS) were measured at midwinter only. At the end of the winter appointment, base commanders evaluated the performance of all personnel. Results: The variations in external light (darkness during winter, midnight sun during arrival and departure) did not influence the diurnal rhythms. The normal peak level in the morning, and the normal and gradual fall towards the evening were observed at arrival, midwinter, and before departure. Immediately after arrival the cortisol values were relatively high and correlated positively with base commander’s evaluation of performance. During midwinter, approximately 58% scored for depression on the Burnam scale. However, when examining these data more closely, only 4 participants (7%) reported depression, the main reason for the high score on the depression scale was related to sleep problems and tiredness. Conclusions: There was no indication that over-wintering led to any disturbance in the diurnal rhythm of cortisol in British Antarctic personnel. There were no other indications of any ‘over-wintering syndrome’ than reports of subjective sleep problems and tiredness.last_img read more

Organisms and responses to environmental change

first_imgThere is great concern currently over environmental change and the biotic responses, actual or potential, to that change. There is also great concern over biodiversity and the observed losses to date. However, there has been little focus on the diversity of potential responses that organisms can make, and how this would influence both the focus of investigation and conservation efforts. Here emphasis is given to broad scale approaches, from gene to ecosystem and where a better understanding of diversity of potential response is needed. There is a need for the identification of rare, key or unique genomes and physiologies that should be made priorities for conservation because of their importance to global biodiversity. The new discipline of conservation physiology is one aspect of the many ways in which organismal responses to environmental variability and change can be investigated, but wider approaches are needed. Environmental change, whether natural or human induced occurs over a very wide range of scales, from nanometres to global and seconds to millennia. The processes involved in responses also function over a wide range of scales, from the molecular to the ecosystem. Organismal responses to change should be viewed in these wider frameworks. Within this overall framework the rate of change of an environmental variable dictates which biological process will be most important in the success or failure of the response. Taking this approach allows an equation to be formulated that allows the likely survival of future change to be estimated: Ps = (f(PF) x f(GM) x f(NP) x f(F) x f (D)xf(RA)) / (Delta Ex f(C)x f(PR) x F(HS)), where Ps = Probability of survival; PF = Physiological flexibility; GM = Gene pool modification rate; NP = number in population; F = Fitness; D = Dispersal capability; RA = Resource availability; Delta E = rate of change of the environment; C = Competition; PR = Predation and parasitism; HS = Habitat separation. Functions (f) are used here to denote that factors may interact and respond in a non-linear fashionlast_img read more

Phil Spencer: Why are thousands of leasehold houses still being sold?

first_imgTV presenter Phil Spencer has savaged new homes builders for continuing to sell leasehold houses despite the recent miss-selling scandal that rocked the construction industry.His property advice site MoveIQ says its research shows 2,600 leasehold houses have been sold since the government announced it would introduce a ban a year ago. The revelation is shocking because many of these houses are being sold via the tax-payer funded Help to Buy scheme.MoveIQ says Land Registry figures show 26,024 new-build properties have been sold with leaseholds since last December’s government announcement, 2,644 of which were houses.And data from the Ministry of Housing, Communities and Local Government shows that during the first six months of 2018, nearly 6,000 leasehold homes were bought with assistance from the Help to Buy scheme, of which 1,340 were houses.Financial problemsBuyers can face crippling financial problems after they move in. This includes huge ground rent increases and finding they are unable to sell their homes while some are charged large sums to make even minor changes to their homes.Earlier this year the NAEA conducted research that found a third of those who had bought leasehold houses had subsequently struggled to sell them.In October a group of 500 newbuild property owners instructed a leading law firm to seek compensation over their mis-sold leasehold apartments and houses.After announcing its intention to ban such sales a year ago, the government is due to announce plans to tackle the problem, along with other leasehold reforms, following a consultation that ended last month.“A year on from the Government’s pledge to ban the sale of new build leasehold houses, thousands of buyers are still being allowed to sleepwalk into leasehold limbo,” says Phil Spencer.“And in a further, ironic twist, many are even being encouraged to do so by the Help to Buy scheme.“When the ban comes in, there should be some redress for the thousands who have bought leasehold houses. At the very least they should be given first refusal on the freehold of their home at a reasonable rate, before it is sold on to a third party.”Phil Spencer leasehold houses leasehold ban NAEA December 31, 2018Nigel LewisWhat’s your opinion?

Synergy unveils fat-reducing flavour ingredient for baking

first_imgSource: Synergy FlavoursSynergy Flavours has launched an ingredient that replicates the typical taste and texture of baked goods but enables ‘significant’ fat and calorie reduction.The flavour and ingredients company says the all-natural innovation can be used for a range of products including muffins, cakes, cookies, biscuits and morning goods.In Synergy’s tests, the new ingredient was used for a reduced-fat muffin recipe and enabled a 37% reduction in fat, as well as 22% less saturated fat and 14% fewer kcals. The company said this was achieved while “delivering comparable sensory qualities that would be expected of a full fat bakery product”.“The sensory panel made comparisons between the full fat, reduced fat control and recipe with the solution, scoring on indulgence, sweetness, creamy mouthfeel and overall aroma,” it added.Pressure continues to build on the baking industry to reformulate to reduce the calorie content of foods. However, according to Mintel, while 70% of consumers feel that manufacturers have a duty to make unhealthy foods healthier, 84% would also agree that taste is the most important factor for them when choosing a product.“We are fully committed to improving the dietary health of the nation by using our flavour technology and our taste modulation platform to support reformulation of lower calorie products,” said Ian Butler, innovation director at Synergy Flavours.“This new, innovative technology can help manufacturers in achieving the challenging goal of reducing calories while maintaining the flavour and indulgence that consumers expect,” he added.The new product follows Synergy’s range of natural flavourings for sugar reduction in biscuits and cookies, launched in 2017. Consumers, Covid and clean label baking – what’s next?Want to know more about reformulating baked goods and keeping things clean label? The be sure to tune into British Baker’s webinar on Thursday 18 March at 1pm.Clean label has been identified as one of the top trends for the bakery market in 2021, particularly with regards to ‘healthier’ products.In this webinar, British Baker and a panel of industry experts will explore what clean label means to consumers and those in the industry, how bakery manufacturers and suppliers can tap into it and whether it’s possible to reformulate to make products healthier while keeping things clean label.Confirmed speakers incude:Emma Clifford, associate director – Food and Drink Research UK, MintelAndrew John Flounders. senior applications specialist, IFFTo find out more, and to register for the event, click here.last_img read more

For Ruby Sales, long road to hope

first_imgOn the morning of Aug. 20, 1965, the fates of Ruby Sales, a 17-year-old black activist from Georgia, and Jonathan Daniels, a white Episcopalian seminarian from New Hampshire, crossed in the struggle against segregation in the South.That day, Daniels gave his life to save Sales’ when he stepped in front of a white man who pointed his gun at her. Despite Sales’ testimony, the man who killed Daniels was acquitted by an all-white jury after claiming self-defense. Sales went on to become a theologian and a civil rights legend. Her contributions as a member of the Freedom Movement are highlighted in the National Museum of African American History and Culture’s Civil Rights History Project. She has continued her work at the helm of The SpiritHouse Project, which she founded in Atlanta to bring people together to fight for social and racial justice.  Sales will speak Monday at the 4 p.m. at the Divinity School. The event will also be live-streamed. The Gazette interviewed her about her life and activism.GAZETTE: You were born in Alabama but grew up in Columbus, Georgia. What was it like to grow up in the heart of segregation?SALES: Blacks couldn’t use public services or facilities, and we had to ride on the back of the bus. There were simple things like not being able to reach into the ice cream box and get your own ice cream, not being able to try on clothes in clothing stores, and being relegated to certain sections of department stores. There were signs everywhere that this was a white supremacist culture. In addition to that, there were lynchings like that of Emmett Till and other black people, so there were constant signs of white violence and terrorism throughout communities in the South, and Columbus, Georgia, was not unique. But even if in these places there was segregation, or what I call Southern apartheid, there were two cultures running simultaneously. One culture was white supremacist that was filled with white terrorism and laws of containment and surveillance against African-Americans. At the same time, there was a counterculture of resistance and accommodation by African-Americans, who created cultural and spiritual modalities that allowed us to survive, resist, and thrive without becoming broken wingers.GAZETTE: Where did your views about social and racial justice come from?SALES: Even within Southern apartheid, my family had certain privileges that the average black person did not enjoy, based on my father’s economic security from being in the military, where he was not beholden to a white power structure for his income.As a child, I was not deeply conscious of the constraints of segregation because our parents were spiritual and cultural geniuses who made the arid soil of segregation fertile with hope, aspiration, creativity, and intellectual scrutiny. And so I did not grow up feeling the weight of segregation on my back. It was only when I went to Tuskegee and began to read and talk about segregation that I began to understand more.GAZETTE: You were a student at Tuskegee University when you decided to join the Civil Rights Movement. What was the turning point for you?SALES: At a very subconscious level, what led me to the movement had been developing in my household. My father was a person who talked about the contradictions between him, as an adult in the Army, fighting for democracy abroad when he couldn’t exercise the prerogatives of democracy at home. He would go on what we would call a historical lesson and we would roll our eyes at him and say, “Here he goes again.” And that stuff gets to you despite your resistance, and then, years later, everything he said is confirmed in the classroom by the teacher you respect, and you go, “Oh, my God.” A light bulb goes off, and you say, “Wow, Daddy was right.” It is also important to understand that we were not fighting for privileges; we were fighting for rights that white people denied black people in the South.GAZETTE: You were 17 when you were arrested after a demonstration in Alabama and you spent a week in jail before the horrible incident in which Jonathan Daniels was killed. What went through your mind when you were in jail?SALES: We were worried about being tortured and raped. Of all the people in jail, we were four women, and no one was over the age of 18. Jonathan Daniels was also in jail. The circumstances were horrific and frightening to a woman alone in the South in the face of history of white male rape against black women for nearly 400 years. It was a terrifying experience and we gained strength from the protest songs and the spirituals we sang. The jail had been a site of terror, shame, and torture for black people, but we turned it into a badge of honor and resistance. We showed that we were willing to go to jail and face up to rape and torture for freedom. We also showed that black mothers throughout the South had fear, but set aside their fear for the good of the community. My mother knew the terrors of white supremacy, but she said to me, “If not my child, whose child?” Black mothers supported the movement with a tear in one eye and a brown bag with food in one hand. That’s the part of the story that never gets told.GAZETTE: Jonathan Daniels was killed by a white man who wanted to kill you. How did it affect your life?SALES: I had always had a steady preoccupation for social justice, but Jonathan Daniels’ assassination and the fact that he saved my life intensified my passion for freedom. But I didn’t carry his death as a burden of guilt or as a weight. I carried it as a commitment. Nor did it make me bitter, because how I could be bitter in the midst of such generosity with someone who saved my life? I was glad that I met Jonathan, and other people in the movement, because it helped me understand that white people are not one-dimensional, that they are also constrained by the system of white supremacy. Jonathan Daniels thought that part of his journey was to redeem the soul of white America because he understood that racism was not something that simply happened to black people. It also happened to white people because it contained them in isolated communities where they lived in fear, so his journey south was not only an attempt to understand and connect with the humanity of others — it was also to connect with his own humanity.GAZETTE: Has the country made progress with respect to race relations?SALES: I don’t like to talk about race relations because that is a benign word. We have to talk about systemic oppression, we have to go beyond talking about having a good relationship with a white or black person because the goal in a struggle for human dignity and the right to live in a society unencumbered by militarism, racism, and materialism should be more than that.GAZETTE: In your opinion, how has the country has dealt with the legacy of slavery?SALES: I don’t think the county has dealt with the legacy of rape, genocide, land theft, captivity, slave codes, segregation, and all its policy of racial containment. While I’m an African-American person, I first and foremost begin the story by looking at the genocide and the land theft from our indigenous brother and sisters. That’s where we should begin the conversation. Because when people say, “America has always been great,” I’d say that there have been strands of greatness in America, but great is an absolute term that does not comply with the realities of our history. What’s often been white people’s greatness has been black people’s nightmare.GAZETTE: What’s your take on Black Lives Matter movement?SALES: Black Lives Matter represents a valid cry of black people all the way from captivity to enslavement to migration to Southern apartheid. It is valid to say “black lives matter” in a society that objectifies and dehumanizes black lives, and said that we did not matter, that we were property, that we were objects of white people’s desires.GAZETTE: And finally, what do you hope to accomplish with your work at SpiritHouse Project?SALES: I’m not going to walk 50 miles anymore in my age. I’m not going to stand in the rain for more than a second because I don’t want to get pneumonia. I see myself as a teacher. My greatest strength is the accumulated knowledge I’ve gained over the years, which allows me to point out things to people, from which we all can learn. So when people say that racism is not an American value, referring to Donald Trump and his racism, I’m able to go back in time and show them that not only is it part of the American value system, but it is also part of our history.But even in the face of challenges, there are reasons for hope. Freedom must be seen as a constant struggle. We don’t have to give in to despair. The reading of history should give us hope because as Martin Luther King Jr. said, “No lie can last forever,” and, “The arc of the moral universe is long, but it bends towards justice.”This interview has been edited for length and clarity.last_img read more

DeSTEMber: A Great Time of Year for More STEM Fun!

first_imgMany schools have some sort of break in the last month of the year. As a mom, I can say that the downtime during these breaks is somewhat welcome, but I don’t want the learning to stop just because school is not in session. Many families and children are spending their month focusing on just a few short days of celebration, with the rest of the time waiting around for those celebrations to begin. At Girlstart, we subscribe to the belief that STEM fun (and learning) is everywhere and should be a part of our everyday experience. We also believe that when children take a break from their studies, it’s a great opportunity for parents, caregivers, and children to have STEM fun together, at home.But unfortunately, it’s hard to drop everything and take time to dig around for a STEM activity. I can say this (in our mutual confidence) as a parent who is also juggling life, work, and parenting. It’s okay. We know. That’s why at Girlstart, the last month of our year is officially known as ‘DeSTEMber,’ and we view it as our job to help you have a fun, memorable experience with your child that is also supportive of their learning.I remember when I was a child, some of my friends had those cardboard boxes with 31 cutout flaps, behind each of which was a chocolate. I never got one. But wow, did I want the joyful anticipation of being able to have a new treat each day. So, at Girlstart, during this special month dedicated to all things STEM, we give that experience to you and your family via our DeSTEMber website. Just like those daily treats, we bring you and your family a new, free, downloadable activity every day. These activities are easy and fun to do, using materials you generally can find at home, or that can be obtained during the weekly shopping run.And it’s not just for families. DeSTEMber is our gift to educators, as well. These activities can be used throughout the year as icebreakers, warm-ups, or activities when you want to have a break and enjoy some STEM fun. We even align them to state and national science standards so you know how Girlstart’s work dovetails with your classroom’s learning goals.Girlstart has been working on DeSTEMber since 2011, and every year we give you something new. As a result, more than 180 fun activities—plus even more activities posted to our blog!—await you! Come join us during our most festive time of year and take a look at our ideas!Best wishes from your DeSTEMber elf,Tamara Hudgins, Ph.D.Executive Director************Tamara Hudgins, Ph.D., is the Executive Director of Girlstart. Since 2009, Girlstart After School has grown from 4 to 65 programs and has been recognized as the most robust program of its kind in the nation, reaching over 20,000 girls, teachers, and family members each year. Hudgins has served in the nonprofit, philanthropic, and higher education communities in Austin, Chicago, and in Central Europe for 20 years, and earned her Ph.D. from Charles University in Prague. “And mom and dad can hardly wait for school to start again!” This refrain from the song, “It’s Beginning to Look a Lot Like Christmas” rings true for a lot of parents, no matter how much they may enjoy the holiday season and extra time with kiddos who are out of school. Our guest blog today comes from Tamara Hudgins, Executive Director of Girlstart. Girlstart is an organization focused on inspiring young girls and teens to take an interest in STEM (Science, Technology, Engineering and Math) fields, and a long-time Youth Learning partner of Dell. Dell’s Youth Learning programs help kids around the global have better access to technology and a quality education and is a key focus of our Legacy of Good plan. Tamara is here to share her tips on how to engage both girls and boys in fun, easy STEM activities this month, which she and her organization call, DeSTEMber.************last_img read more

Panama Canal Expansion Completed

first_imgBy Mass Communication Specialist 3rd Class Desmond Parks, Navy Public Affairs Support Element July 01, 2016 Leadership aboard Harpers Ferry-class dock landing ship USS Oak Hill (LSD 51), alongside Commander, United States Southern Command Adm. Kurt Tidd and U.S. ambassador to Panama John D. Feeley, hosted a Panama Canal Expansion ceremony while in port Balboa, Panama, June 25. The ceremony marked the opening of a $5.4 billion expansion of the Panama Canal that spanned over the course of a decade, allowing larger ships to pass through the canal and significantly improve long-term global trade. “The Panama Canal is the most important economic feature of this region,” said Adm. Tidd. “It connects the economic livelihood of nations all around the world.” In preparation for the expansion, ports on the East Coast of the U.S. and in the Gulf of Mexico have invested over $30 billion in deepening channels and building new loading docks to prepare for greater traffic and increased trade, according to the American Association of Port Authorities. Although there isn’t an expectation for immediate improvement in global trade, the expansion is expected to directly benefit both security and trade within the region. In addition to guest speakers, Adm. Tidd and Ambassador Feeley, U.S. Second Lady Dr. Jill Biden also attended the ceremony and met with Sailors, Marines, Soldiers and U.S. embassy officials to celebrate the Panama Canal expansion. “Oak Hill is extremely proud to be able to participate in this historic event,” said Cmdr. Orlando Bowman, commanding officer aboard Oak Hill. “The ability to represent the U.S., as well as continuing to strengthen our partnership with Panama is an incredible experience for the crew.” “U.S. Southern Command is the organizer for one of the largest multinational exercises involving over 21 nations this year engaged in the security of the Panama Canal,” said Adm. Tidd. “All of the countries of the region and beyond have a shared responsibility working hand-in-hand with the government of Panama to secure this important economic item.” PANAMAX brings together partner nations to participate in training scenarios from various U.S. locations to increase interoperability among participating nations. The main focus of the exercise is to guarantee safe passage through the Panama Canal, ensure Panama’s neutrality and respect its sovereignty.
