Respiratory responses to chilling and freezing in two sub-Antarctic insects

first_imgThe effects of chilling (to temperatures above the supercooling point, SCP) and freezing on respiration of adults and larvae of two coleopterans living on sub-Antarctic South Georgia (54°S, 37°W),Hydromedion sparsutumandPerimylops antarcticus(Coleoptera, Perimylopidae), were quantified. Respiration rates of individual insects (live weights, 11–21 mg) were measured at 10°C prior to chilling (−4°C) or freezing (SCP range −3.8 to −5.3°C) and posttreatment. The species possess a small amount of freeze tolerance in both adults and larvae. Chilling had no significant effects on respiration rates ofP. antarcticusandH. sparsutum,although mean levels were depressed by 6–15%. Freezing produced considerable enhancement of respiratory activity. Mean values increased postfreezing in larvae (+34%) ofH. sparsutumand in both larvae (+44%) (P< 0.01) and adults (77%) (P< 0.05) ofP. antarcticus.Chilling and freezing had different effects on respiration rates andP. antarcticusshowed the greatest metabolic response to freezing.last_img read more

Octogenarian receives diploma from Oxford

first_imgAn 82 year old woman has taken a diploma in Local English History from Oxford University.Margaret Broadbent told the Continuing Education department, “In May 2009 I had to give up driving because of vision problems so I decided that I needed a new focus for my life. For the previous few years I had taken the Department’s weekly courses in various subjects, including Literature and History, and had always enjoyed them. I had often wondered about doing a Certificate or Diploma course, and I thought I’d give it a try. I was aged 80 when I applied to do the Undergraduate Diploma in English Local History.”She said the main surprise she had experienced during the course had been the enormous amount of help she received because of her visual disability. Encouraged by her tutor, she went to see the Student Advisor at the start of her second year because she was aware of increasing visual difficulty and concerned that she might not be able to finish the course.The Advisor told her to apply for a disability grant to purchase suitable equipment. She assisted Broadbent with filling in forms. To Broadbent’s surprise, her application was accepted by Student Finance England and, after assessment, she was provided with computer equipment to help with writing assignments and accessing online resources.Broadbent said that she enjoyed the lectures and meeting other students, and found the tutorials very valuable. She also claimed that the library staff had been extraordinarily helpful and made her feel very privileged to be able to use the Bodleian and sit in the Radcliffe Camera. Broadbent found writing the assignments the most challenging, especially in her second year as both her vision and her memory had deteriorated slightly.She said, “The course was very interesting and I’m really glad I did it. There’s a great deal of help available from all sides: the excellent tutor, the Student Advisor and the library staff. And Rewley House is a very friendly, welcoming place to study.”http://www.conted.ox.ac.uk/last_img read more

Warrens plans to expand in St Just

first_imgThe directors of Warrens Bakery hope plans to grow the company’s St Just production site will enable them to extend the confectionery side of the business.The bakery recently renovated its current site within St Just, where it was established in 1860. It has since become a county-wide chain.The site currently employs 123 people, with 50% living in the local area and the remainder from Penzance or other nearby locations, but it is anticipated the new plans will create more jobs.Jason Jobling, Warrens’ director, said: “The plans are key for our business. Over recent years our business has gone through a bit of a torrid time, and we’ve changed it recently over the past couple of years and started to develop it to grow it back again.”He added: “If we don’t get this, it could put us backwards – which we really don’t want to do.”Plans to extend the current site on Boswedden Road will cost around £700,000, which is to be largely financed through grant funding. This will include an extension to the existing confectionery production unit, as well as staff facilities.Unveiled at a town council meeting last week, the plans were greeted with strong approval by St Just Town Council.Town councillor Neil McFadden described the plans as “one of the best things that has happened to this area in years”.Traffic and parking concernsHowever, some residents are concerned the plans could add to the town’s traffic, parking issues and noise pollution.St Just resident Moira Wilson said: “Some [employees] already park on the pavement at times. By reducing the space for parking available to workers the parking problems will be increased.”Jobling responded: “It is intended to encourage a cycle-to-work scheme and additional covered cycle racks are included in the application.” He added that additional flour deliveries were only expected to increase from once every 14 days to once every 12 days.Last week, Warrrens Bakery won the Open Savoury category at the World Pasty Championships.last_img read more

How the Socratic method translates online

first_img University offers coronavirus resources and help guides ‘Unsteady,’ ‘lucky,’ and ‘overwhelmed’ Related On March 23, Harvard Law School shifted to remote teaching and learning, as part of Harvard University’s effort to limit the spread of COVID-19. Harvard Law School (HLS) Professor Jeannie Suk Gersen ’02, who had never taught virtually, immediately began preparing to move her class of 115 students in “Constitutional Law: Separation of Powers, Federalism, and Fourteenth Amendment” online before spring break. She taught her first class via Zoom on March 11. Harvard Law Today spoke to Gersen via email about her quick switch to remote instruction.Q&AJeannie Suk GersenHarvard Law Today:  When did you start preparing to move your class online?Jeannie Suk Gersen:  I started preparing on Tuesday [March 10] morning before spring break, as soon as we received the message from President [Larry] Bacow. I notified students that morning that we would start Zoom classes the next day. I attended a training at HLS that afternoon with my TAs, and then did an optional practice session for the class that evening. On Wednesday at 1 p.m., we were having class online, talking about the Privileges and Immunities Clause.HLT:  How did the students react?Gersen:  The students reacted quickly to jump into class on Zoom. They were terrific. My TAs were also a godsend. Students were shocked and distressed by the announcements that they would have to leave their housing — and some of them even would have to leave the country — as their semester together on campus as HLS students was at an abrupt and sad end. That was extremely stressful. I heard from students that in the midst of that week they found it comforting to become familiar with how an online class would work and to see that it would be alright. In all the uncertainty, they headed into spring break with a good sense of what our class would be like going forward.HLT: You use the Socratic method in your classes. How has that translated to online teaching?Gersen: I find Zoom to be highly compatible with Socratic teaching. It is easy to call on students and have lively exchanges with them, face to face. Several students remarked afterward that their classmates seem less nervous and more prepared while speaking on Zoom than in a large room of 115 students. I, too, found the experience of teaching on Zoom surprisingly more personable and less performative than standing at a podium at the front of a large lecture hall. An example of how in some respects online interaction might feel less distancing than in-person teaching.I have some lecture bits that I intersperse with my Socratic teaching. I found those bits harder to get through. When I’m just talking at the screen, with the students’ microphones muted (to prevent background noise), there’s no laughter to be heard at any jokes or what I think of as funny parts. It’s hard to know if you’re totally bombing and the “audience” just thinks you’re a dud! You can’t be a diva on Zoom. It is really about the conversation and exchange with students, which is fine with me.HLT: I know it’s only been a couple of days, but how has the experience been?Gersen: I know it’s supposed to be less ideal than in-person classes, but I am enjoying the experience and excited to discover new insights for pedagogy.HLT:  What are you looking forward to most as classes resume?Gersen: I’m looking forward to connecting with students, seeing their kindness and good will, and continuing to pursue knowledge and learning together as long as we can.HLT:  So many of us are working remotely now (some with a full house: kids, partner, pets). Do you have advice on managing work-life balance while working from home?Gersen: It’s OK to let some things go. But after a few days, it can also be surprisingly helpful to get out of the fetal position, change out of your pajamas, and make the bed. I say this aspirationally.

Schedule lawn care

first_imgEvery year, local county Extension offices receive hundreds of phone calls from homeowners with questions about when to do this or that to their lawns. When do I fertilize? When do I plant grass seed? When do I core aerate? When do I apply pre-emergent herbicides? Calendar available onlineTo assist homeowners and landscape professionals, the University of Georgia Turf Team created a one-stop website with current, research-based information on lawn care in Georgia at www.georgiaturf.org. One of the most important tools that consumers can use in lawn maintenance is a lawn calendar. The turf team website has a lawn calendar for each turfgrass species that can be grown in Georgia: bermudagrass, centipedegrass, tall fescue, zoysiagrass and St. Augustinegrass.Every homeowner should get a copy of this lawn calendar for their lawn type and keep it handy. If you don’t have access to the Internet, stop by your local UGA Cooperative Extension office and get a free lawn calendar, or call 1-800-ASK-UGA1. Know your grass and its needsProper lawn care can be confusing. For starters, the average homeowner doesn’t even know what type of grass he has. There are many herbicides that are only labeled for certain lawn types. If you spray a herbicide that doesn’t have your lawn grass listed on the label, there is a good chance you will kill your lawn. Never assume that just because it is labeled for one grass that it can be used on all lawns. If your grass isn’t on the label, don’t use it!The rules are different from state to stateThere is a lot of confusing information on the Internet and on various lawn products about when is the best time to do anything to your lawn. The how and when to fertilize your lawn or when to apply herbicides varies depending on where you live. When to do these tasks in Ohio is not going to work in Georgia and vice-versa because lawns can grow on completely different schedules, depending on temperature, climate zones and rainfall patterns.Remember, every lawn type has a unique maintenance schedule. For example, cool-season grasses such as tall fescue should only be fertilized in the spring and fall. On the other hand, warm-season grasses that go dormant, like bermudagrass, should only be fertilized after soil temperatures at the 4-inch depth are consistently 65 F and then throughout the summer. Warm-season grasses should never be fertilized in the winter. Their dormant roots while will not take up the fertilizer. You basically end up feeding the winter weeds.Healthy grass wins out over weedsMost insects, diseases and weeds that affect lawns can be minimized or avoided just by simply providing the proper maintenance at the right time. A thick, healthy turfgrass can out-compete most weed problems and can better tolerate insects, diseases and drought stress. An added benefit to managing your grass properly is that you won’t need to use as many pesticides. Managing your grass properly begins with sticking to a lawn calendar made for Georgia and not watching what your neighbors are doing. Once you get your proper Georgia lawn calendar, be a good neighbor and print some for neighbors and friends so they can keep a copy handy, too.last_img read more

Chittenden County DMV office moving from Burlington to South Burlington

first_imgVermont Department of Motor Vehicles Commissioner Robert Ide announced today that the Department will be moving its Chittenden County office from its current Burlington, North Avenue location to 4 Market St. in South Burlington. The move will occur over the weekend of July 15-17 and will require the DMV to close the North Avenue office at noon on Friday, July 15th.  The new office in South Burlington will open for business at noon, Monday July 18th. ‘We pride ourselves on the quality service we provide to Vermonters. However, in order to ensure a successful move, with all the logistics involved, it is necessary to close our Chittenden County operation from noon Friday until noon on Monday.’ Commissioner Ide said.   The move from the North Avenue location is due to a construction project currently underway at that site and scheduled to continue for the next two years. ‘The North Avenue location has served the Department well for many years. With the on-going construction at the old Thayer School site we feel extremely fortunate to have found quality office space for both our employees and our customers that has allowed us to remain in the Greater Burlington area.’ Commissioner Ide added. A grand opening for the new DMV office in Chittenden County will be announced at a later date.last_img read more

Court finds violations of Vermont’s campaign finance law

first_imgThe Vermont Superior Court, Washington Unit, issued a decision on Tuesday in favor of the State in its campaign finance law enforcement action brought against the Republican Governors Association (’RGA’). The Court found that the RGA ran two political advertisements from August to October 2010, one promoting candidate Brian Dubie and the other attacking candidate Peter Shumlin, but did not register with the Secretary of State’s Office or file required disclosure reports. The Court also found that the RGA accepted contributions in excess of $2,000, in violation of Vermont’s limit on contributions to political committees. The RGA advertisements were in addition to others that it broadcast in the name of its Vermont PAC, Green Mountain Prosperity PAC (’GMP’). The RGA’s total spending on the Vermont gubernatorial race in 2010, both directly and through GMP, was over $900,000.This is a similar finding to one against the Democrats in June involving the same Dubie-Shumlin race with an organization called Green Mountain Future (CLICK HERE FOR STORY).The Court rejected the RGA’s argument that national organizations such as itself cannot be regulated under Vermont’s campaign finance law. It ruled that if a PAC raises and spends more than $500 to support or oppose a candidate for Vermont office, it must follow Vermont law, regardless of whether it is also involved in political work in other states.In addition, just as it did in the State’s other enforcement action against a PAC run by the Democratic Governors Association (’DGA’), the Court ruled that the RGA’s advertisements were clearly intended to advocate for or against a candidate. Dismissing the idea that these were issue ads, the Court said that the ads ‘can be understood only as a call to vote for one man and to vote against the other.’ The Court found that it was ‘obviously Senator Shumlin’s role as a candidate for statewide office which explains the decision of a national political organization to buy airtime in Vermont in order to criticize his record on the local property tax.’ Further, ‘no other communication except a campaign ad or a stump speech is likely to describe Lt. Governor Dubie with such focused warmth and approval’ as the RGA’s ‘Vision for Vermont’ advertisement. The Court observed that ‘it takes no sophistication to understand these messages.’Ruling that the reporting requirement and the limit on contributions to PACs are constitutional, the Court held that the ‘RGA’s perceived problem’ of compliance was ‘one of its own creation.’ It explained that the RGA had set up a Vermont PAC which appeared to accept only contributions under $2,000, but ‘nevertheless chose not to use it for these advertisements.’ Rather, the Court noted, the RGA ‘attempted to skirt state regulation’ and ended up violating Vermont law.The court has yet to impose penalties in either the DGA or RGA cases.‘We are pleased with Judge Crawford’s decisions,’ Attorney General William Sorrell said. ‘This Office will continue to evenhandedly enforce Vermont’s campaign finance laws.’ Source: Attorney General. 10.6.2011RELATED: Court finds violations of Vermont’s campaign finance law by Green … Jun 29, 2011 … The Vermont Superior Court, Washington Unit, issued a decision yesterday in favor of the State in its campaign finance law enforcement action …last_img read more

Latin American Media Slam Government, Drug Gang Controls

first_imgBy Dialogo November 11, 2010 Hello, I am a Cuban in Ecuador. Like me there are many that for more than a year have lost their Cuban residency and are not wanted over there and here in Ecuador we have no papers and many of us are illegal and we need help with human rights because no one here listens to us. Everything here is closed to us. We ask for help from the United States to support us and to remember that the Ecuadorans also immigrate and that Cuba does not support us in anything since we got out of prison to be free. Cuba is like Alcatraz Prison and does not leave us alone even out of the country. Latin American media leaders complained on 9 November that freedom of the press was being hurt by limits from regional governments as well as brutal violence from drug gangs. “The press has two big enemies. On the one hand (are) intolerant, authoritarian governments who wish to control information. Attacks from organized crime and drug traffickers have the same end,” said Gonzalo Marroquin, the newly elected head of the Inter American Press Association, holding a two-day meeting in southeast Mexico. More than 14 journalists were killed in the region in the first half of 2010 alone, including seven in Mexico, five in Honduras and two in Brazil, said a statement from representatives of more than 1,200 media, in the city of Merida. A common theme was the impunity under which the killings took place, it said. The pan-American body called on Mexico, which has seen attacks on journalists surge amid a wave of drug-related violence, to recognize crimes against media workers as a federal offense to improve chances of prosecution. The group also highlighted at least nine journalist killings in Honduras in 2010 alone, in the aftermath of a 2009 coup, with most cases still unsolved. The media leaders criticized Argentina, Ecuador, Bolivia and Venezuela for seeking to curb freedom of expression through legislation or by violating laws. They also called for the immediate release of independent journalists imprisoned in Cuba and an end to harassment of bloggers and correspondents on the Communist island. Their next meeting will take place in Lima, Peru, in October 2012.last_img read more
