The fine structure of an algal mat from a freshwater maritime antarctic lake

first_imgThe three-dimensional microstructure of Tolypothrix mats from the bottom of a maritime antarctic lake of Signy Island, South Orkneys, was examined. Samples from mats at two depths, 4 and 6 m, within the lake were taken by scuba divers and frozen (−80 °C) in March 1987. The samples were freeze-fractured and examined by ambient and low temperature scanning electron microscopy (LTSEM). The mats shared a similar structure consisting of a compact lower zone of prostrate filaments and an upper zone of loose vertical filaments. An outer layer of extremely loose spreading filaments was only found by LTSEM, leading to the conclusion that some collapse of the mat structure occurred during dehydration for ambient SEM. Fine detail of the mat matrix such as the attachment of epiphytes and associated microfauna to the filaments was often obscured by mucilage. Fast-particle etching was used to remove this mucilage and also the organic coat that covers uncleaned diatoms, thereby allowing the identification of attached cells in situ. A variety of attachment strategies were observed although sessile forms were most common. Further fast-particle etching of the epiphytic diatom assemblages revealed that many of the attached diatoms were devoid of cell contents. Together with the epiphytic diatoms a variety of microfauna were identified, both incorporated within the mat and on the mat surface. The implications of these observations are discussed.last_img read more

Ceremony Held at HMS Royal Oak Memorial

Disgruntled applicant makes 40 FOI requests

first_imgOxford University chiefs have noted that there are problems with current Freedom of Information laws, after being inundated with over 40 requests for information about a course from a failed applicant.The University told a Parliamentary inquiry into FoI that the Freedom of Information Act provided insufficient protection from ‘vexatious’ requests such as the one by this student. Oxford remarked that this case demonstrates that FOI laws, which ensure the public has the right to access information held by public authorities, should change.A University spokesperson stated, ‘A lot of the current problems come from how many people use FoI to go on ‘fishing expeditions’ rather than making carefully considered and specific requests.’The University received 330 FoI requests in 2011, compared to just 185 in 2005 when the Freedom of Information Act came into force. The spokesperson noted that just under a third of all requests have come from student journalists, with other requesters being the national press, special interest groups or ordinary members of the public.However they stated that these requests can often appear trivial, commenting, ‘People should bear in mind that FoI uses up University resources and that material very similar to their request is often already publically available online.’Merton College Dphil student Chong Chen disagreed with the university’s stance, saying, ‘I don’t see how this extreme example is a well-grounded reason to change the system. Honestly, I don’t even see 330 requests as a lot to handle.’ He added that the most requests are probably honest, and that this angry applicant was probably just a ‘nutter.’First year PPEist Angus Barry agreed, stating, ‘My impression is that FoIs have done a lot of good and it would be difficult to change the laws about them to accurately remove those which are just wasting time.’Law student Abigail Bridger added, ‘[Vexatious requests] are an inconvenience, but a trivial one compared to the other things that the Freedom of Information laws protect.’last_img read more

Written harassment

first_imgVerbal bullying can be caught by harassment laws. But suppose employees do it in writing? What is the Court of Appeal’s view on this type of behaviour?Some years ago, the House of Lords confirmed that the Protection from Harassment Act 1997 (PHA) could be used by employees against their employers. As this particular law was originally designed to combat stalkers not to provide further means of redress for disgruntled members of staff this was bad news. At that time, their Lordships ruled that:l the PHA covers any form of verbal harassment (no breach of discrimination law is necessary);l an employee need only show they have suffered two incidents of “anxiety or distress” caused by their employer;l there is no statutory defence available to a PHA claim;l employees have six years to bring a claim against you.Managers and staff should be instructed not to make oppressive and unacceptable comments in written communications, letters, email and text messages. Make it clear in your equal opportunities and dignity at work policy that any breaches of this rule will result in disciplinary action.l For a sample of our ’Equal Opportunities and Dignity at Work Policy’, call 01920 468061last_img read more

Repercussions of gender nonconformity

first_imgChildren in the U.S. whose activity choices, interests, and pretend play before age 11 fall outside those typically expressed by their biological sex face increased risk of being physically, psychologically, and sexually abused, and of suffering from post-traumatic stress disorder (PTSD) by early adulthood, according to a new study led by researchers at Harvard School of Public Health (HSPH). It is the first study to use a population-based sample to look at gender nonconformity as a risk factor for abuse.The study was published online Feb. 20 and will appear in the March 2012 print issue of Pediatrics.Parents need to be aware that discrimination against gender nonconformity affects one in 10 kids, affects kids at a very young age, and has lasting impacts on health. — Andrea Roberts“The abuse we examined was mostly perpetrated by parents or other adults in the home. Parents need to be aware that discrimination against gender nonconformity affects one in 10 kids, affects kids at a very young age, and has lasting impacts on health,” said lead author Andrea Roberts, a research associate in the Department of Society, Human Development, and Health at HSPH.PTSD has been linked to risky behavior such as engaging in unprotected sex, and also to physical symptoms such as cardiovascular problems and chronic pain.The researchers, led by Roberts and senior author S. Bryn Austin, associate professor in the Department of Society, Human Development, and Health at HSPH, and in the Division of Adolescent and Young Adult Medicine at Harvard-affiliated Children’s Hospital Boston, examined questionnaire data gathered from nearly 9,000 young adults (average age 23) who enrolled in the longitudinal Growing Up Today study in 1996. Respondents were asked in 2007 to recall their childhood experiences, including favorite toys and games, roles they took while playing, media characters they imitated or admired, and feelings of femininity and masculinity. They also were asked about physical, sexual, or emotional abuse they experienced and were screened for PTSD.Men who ranked in the top 10th percentile of childhood gender-nonconformity reported a higher prevalence of sexual and physical abuse before age 11 and psychological abuse between ages 11 and 17 compared with those below the median of nonconformity. Women in the top 10th percent reported a higher prevalence of all forms of abuse as children compared with those below the median of nonconformity. Rates of PTSD were almost twice as high among young adults who were gender nonconforming in childhood than among those who were not.The researchers also found that most children who were gender nonconforming were heterosexual in adulthood (85 percent), a finding reported for the first time in this study. “Our findings suggest that most of the intolerance toward gender nonconformity in children is targeted toward heterosexuals,” said Roberts.More research is needed to understand why gender nonconforming kids experience greater risk of abuse, and to develop interventions to prevent abuse, the researchers said. They recommend that pediatricians and school health providers consider abuse screening for this vulnerable population.Funding for the study was provided by the National Institutes of Health.last_img read more

Alma Mater emphasizes student unity

first_imgOne of the most hotly contested debates surrounding the 2013 Notre Dame football team leapt once more to the forefront of conversation Monday as team leaders and representatives from student government met to finalize the players’ decision to sing the Alma Mater after every home game, regardless of outcome.“The fact that this decision was not made by football players alone or by the students alone is a testament to how unified we can be as a student body,” Irish sophomore receiver Corey Robinson said. “The Alma Mater is as an avenue where we can stand together as a unified body and celebrate our common bond: love for Notre Dame.”Observer File Photo Robinson and Irish senior cornerback Matthias Farley represented the Unity Council, a group of football players elected from all class years that acts as liaison between the team and its coaching staff, Robinson said. They met with student body president Lauren Vidal, vice president Matthew Devine and Campus Ministry representative Grace Carroll, all seniors.Robinson, who also represents athletics in student government, said the Unity Council voted unanimously to sing the Alma Mater after every game, a decision that was “nearly unanimously” supported by the team as a whole and reflected the team’s desire to continue a relationship of mutual respect with fans in the student section and beyond.“We were really thinking of the entirety of Notre Dame nation when we made the decision,” Robinson said. “We chose to sing because we appreciate that it’s bigger than just us football players, even us students.“The bottom line is the Notre Dame community is a family,” he said. “Regardless of whether we are celebrating a win or grieving a loss, the most important thing is that we stay together. I can think of no better way to demonstrate this unconditional bond then singing the Alma Mater together after every home game.”The Unity Council made its decision independent of Irish coach Brian Kelly and Director of Athletics Jack Swarbrick, Robinson said. He said Kelly, Swarbrick and the coaching staff “encouraged” him to collaborate with student government in a “joint student effort” to address the issue.“Coach Kelly, his staff and Jack Swarbrick empowered us to make the decision as players,” Robinson said. “They were in communication with us throughout the decision making process and supported our decision as a team.”Farley said the team’s ability to freely determine this season’s Alma Mater policy demonstrated the commitment of players, coaches and administrators to honor the tradition as a way of connecting student-athletes to their peers.“I … think it’s incredible that Coach Kelly and Jack Swarbrick allowed us to make the decision for ourselves,” Farley said. “In my opinion, it makes the decision to continue singing the Alma Mater much more genuine and real coming from the team, especially when there could have been a lot of division amongst us.”Vidal, Devine and Carroll presented Robinson and Farley with a booklet containing student opinions on the Alma Mater to keep the players informed of their peers’ perspectives, Vidal said.“The books contain about 100 quotes from the students — each quote represents that student’s interpretation of the alma mater and what it means to them and our University,” she said.The statements in the booklet mirrored the enthusiasm for the tradition that Robinson and Farley expressed, often lauding the Alma Mater as a symbolic reminder of the values and community within the University as a whole.“Notre Dame values family, faith and community,” senior Shannon Hagedorn said in the booklet. “The players on the team are part of the family and the score at the end of a game played on a Saturday in the fall doesn’t change that fact.“… The Alma Mater is a symbol of our connection, our spirit and our strength in the light and in the dark. Allow the players to sing and sway with their brothers at the end of the day. We belong together.”Senior Kristen Parkinson, president of the Leprechaun Legion, likened the Alma Mater to “a celebration of the Notre Dame family.”“The Legion welcomes the return of this tradition, and we look forward to standing as a united student body, on- and off-the-field, on Saturday,” she said in an email.Controversy surrounding the singing of the Alma Mater first arose after several players left the field of Notre Dame Stadium following the team’s loss to Oklahoma on Sept. 28 without stopping at the student section to sing. The action sparked intense debate among students, alumni and fans, many of whom saw the former policy as equating community with winning alone.“To my understanding, the official policy last season was to not sing the Alma Mater after home losses,” Robinson said. “It was an issue that may have even been decided much earlier than last year, but since we hadn’t lost at home in two years, the policy was not well-known or practiced.”In a press conference Tuesday, Kelly said he raised the issue with the Unity Council and invited its members to revisit the policy.“I addressed it last year with the Unity Council,” he said. “We decided as a team that’s not what we wanted to do. This year we brought it back up to the Unity Council, and they voted that’s something that they wanted to do, so I’m all for what my team wants to do, and we will make that work.”Robinson said some players had expressed concern regarding previous incidents of students booing the team and throwing objects on the field, such as frozen marshmallows during the Nov. 23 game against BYU.“We understand that this is a intense game, but we hope to be treated with respect when we sing the Alma Mater with the student body and fans,” he said.Farley said the Unity Council primarily sought to promote “the respect of both the team for the fans and the fans for the team.”“I would hope that the student body will understand, just as we have, that the singing of the Alma Mater is bigger than all of us and really bonds us together,” he said. “I know that I can speak on the behalf of the team, and there won’t be any behavior issues on our part.”Tags: Alma mater, Brian Kelly, Corey Robinson, football, Jack Swarbrick, Lauren Vidal, Matthew Devine, Matthias Farleylast_img read more

92-Year-Old Woman Detained With Four Kilos Of Cocaine Hidden On Her Body

first_imgBy Dialogo October 21, 2009 A 92-year-old woman and her companion have been detained in the Madrid-Barajas airport by officers of the Civil Guard, who seized 4,300 grams of narcotics hidden on various parts of the arrested woman’s body. According to a statement, the detentions took place on Friday following the arrival of a flight from São Paulo (Brazil). The attitude of one of the travelers on this flight, who was being transported in a wheelchair, aroused the suspicions of the police officers. The elderly woman and her companion were on their way to take a flight headed for the Spanish island of Tenerife, and when the officers moved to carry out the appropriate inspection, the companion began “a crazed flight.” According to sources, the elderly woman was subjected to a search, in the course of which it was discovered that she was carrying several packets with a weight of 4,300 grams of cocaine hidden on her body, for which reason she was detained. Immediately thereafter, a search was begun in Terminal 4 for the nonagenarian’s companion, a 44-year-old woman of Uruguayan nationality, who was trying to leave the Madrid airport and who was also arrested.last_img read more
