Older people and those who work non-standard hours are less likely to feel integrated into society, according to a study funded by the Economic and Social Research Council (ESRC).

"Feeling part of society usually involves participating in certain activities such as sports, the arts, volunteering or social networking," says Dr Matt Barnes who led the research. "Our research shows that older people and those who work unusual hours face particular barriers to participating in such activities."

The study points out that the Government promotes work as the best route to personal well-being, with worklessness going hand in hand with low income and social exclusion. Yet, Dr Barnes' research shows that working uncommon hours can also have implications for people's opportunities to engage and feel integrated in society.

Two-thirds of workers work at unusual times. Although shops and other facilities are beginning to adapt, such workers still find their leisure time constrained by the limited availability of services, as well as other people with whom to spend their free time.

Compared with people who work a standard week (Monday to Friday, between 8am and 7pm), these workers spend less time on face-to-face social and relational activities, particularly if they work in the evening or at the weekend. On average, evening workers spend six hours 43 minutes on participatory activities per week and Sunday workers just over five hours, compared with over eight hours for those who work normal hours.

"By getting people to keep a diary and analysing the way they spend their time over a 24 hour period," says Dr Barnes, "we have been able to understand how they 'participate' and what might be done to create greater social inclusion."

The study also found that older people face barriers to participatory activities. Over one million older people experience poor social relations and social exclusion.

Spending time with friends is an important way of building social networks and support. They can be crucial for older people dealing with life-changing events such as retirement, bereavement or illness - each of which can pose an increased risk of social isolation. Spending time with people outside the household can also provide the elderly with a sense of independence.

The study found that older people who live alone spend a lot of time with friends and acquaintances, but on average, they can also spend eleven hours alone on a week day and ten and a half hours alone at weekends (excluding sleep).

Over a third of the time that older people spend with their friends is devoted to participatory activities - most often social networking such as visiting or receiving visitors, celebrating birthdays and catching up over the phone. Religious activity and doing acts of kindness involving friends are also important participatory activities.

The research also showed that women are more likely than men to spend time with friends on social networking activities. Their ability to participate, however, is limited by housework, caring for others and personal care.

"It is clear that social participation is important for an improved quality of life, both in older age and among those still working," says Dr Barnes. "Improving the accessibility of public transport and other facilities and services would go a long way towards increasing social inclusion in Britain."

These results suggest that local government and charities need to recognise that social participation is important to improve people's quality of life. "Local governments can encourage public leisure complexes and public transport services to operate wider hours or 24/7. Charities could be more aware of these groups when arranging social clubs targeting shift workers and elderly people", Dr Barnes concludes.

The project focused on peoples' participation in a wide range of social and civic activities to explore various aspects of exclusion. The project used the 2000 UK Time Use Survey (UKTUS) to explore the time that people spent on these activities. The UKTUS also collects a wide range of socio-demographic and economic information on individuals and their households via standard questionnaires. This information was used to identify different subgroups of the UK population.

Malaria In Africa - A Logistics Approach

The problems of archaic logistics infrastructure, inefficient distribution channels and disruptive black markets must all be addressed urgently if Africa is to cope with the growing problem of malaria, according to a study published in the International Journal of Logistics Systems and Management.

Historically, malaria is humanity's biggest killer and although it has been eradicated in some regions it remains the biggest infectious threat in many parts of the world. Malaria kills 1.1 million people every year and afflicts 300 million with acute illness. The vast majority of those infected are children under the age of five years. Getting anti-malarial drugs to those at risk across Africa is an enormous problem of economics, politics and infrastructure. Now, Hokey Min of the College of Business Administration, at Bowling Green State University, in Ohio, has identified the various factors that must be considered if this situation is to be remedied.

Min has developed a comprehensive supply chain map that reveals the labyrinths of African logistics infrastructure, distribution channels, government regulations and business customs. This map could help improve access to anti-malarial drugs as well as avoiding disruption to the drug supply chain. He points out that there are countless challenges posed by trade and regulatory barriers across Africa. Communication difficulties, seasonal variations in logistics infrastructure and a high rate of theft and damage during storage and transit also potentially overwhelm any company hoping to distribute anti-malarial drugs in the African market. He suggests that outsourcing of logistics functions to control such risks and costs might be the only solution.

Moreover, African legal and ethical codes have many "subtleties" he says, so it is potentially beneficial to find local partners that can assist with such subtleties. In addition, the chronically poor roads suggest that local transport options, such as donkey carts and bicycles should also be considered as viable modes of distribution rather than a company expecting to transport antimalarials to rural areas in trucks.

Recognizing the idiosyncrasies of drug distribution in Africa is essential to coping with the lethal problem of malaria. "Supply chain efficiency for distribution of anti-malarial drugs is a matter of life and death to many malaria-endemic countries in Africa," says Min. And, although few attempts have been made to tackle the problem, an understanding of the African distribution system and the unique but complicated socioeconomic and regulatory environments affecting African logistics operations is essential. Min's preliminary study on addressing the issues points the way forward to improving a disheartening situation.

Hospital Worker Flu Vaccination Rate Increased By Strict Policy

Article Date: 14 Dec 2011 - 1:00 PST

A California hospital raised its employee influenza vaccination rate above 90 percent by shifting from a voluntary vaccination program to one mandating all healthcare workers either get vaccinated or wear a mask at work for the entire flu season (December through March).

A five-year study of evolving flu vaccination programs at University of California Irvine Medical Center is published in the January 2012 issue of Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America. The results, the authors say, suggest voluntary programs are not enough to get meaningful increases in flu vaccination rates for healthcare workers.

The systematic effort by University of California Irvine Healthcare to raise vaccination rates among its 6,500 employees began in 2006. Initial efforts focused on educating employees and making vaccines free of charge and conveniently available. During the 2007 and 2008 flu seasons, efforts were advanced to also include a mandatory declination strategy, the use of mobile carts and decentralized vaccine distribution by designated nurses in clinical areas.

According to the study, the voluntary campaign raised rates from around 45 percent to 60 percent. "Nevertheless, the use of these campaigns, even over a two-year period, was unable to increase [healthcare worker] vaccination rates beyond 60 percent," the researchers write. "Only the addition of a mandatory vaccination policy enabled instantaneous gains in vaccination to levels above 90 percent."

The mandatory campaign requiring vaccination or wearing a mask while in medical areas began in 2009, raising rates that season to nearly 87 percent. In addition to the mask requirement, employees who were not vaccinated were required to sign a written declination. A real-time tracking tool was also implemented to provide online-accessible lists of compliant and non-compliant staff.

During the 2010 season, the mandatory policy was further strengthened through the involvement of the dean of the School of Medicine. The dean provided lists of non-compliant staff to department chairs and linked compliance with the policy with good-standing department budget allocations. This modification, alongside the cumulative strategies initiated since 2006, raised flu vaccination rates among school of medicine faculty above 90 percent.

"In moving to a mandatory program, we found that the majority of vaccine declinations for medical or religious reasons remained small throughout all flu seasons. In contrast, the proportion of declinations for preferential reasons, like philosophical beliefs or fear of needles, markedly decreased," said Dr. Susan Huang, a professor at UC Irvine Medical Center and one of the study's authors.

"This suggests that the declination policy captures a small number of healthcare professionals who feel strongly about declining, as well as a much larger number who have not made vaccination a priority. The masking requirement for those not vaccinated might have provided sufficient disincentive to encourage healthcare providers to prioritize vaccination."

Despite calls from numerous infection control organizations, including the Society for Healthcare Epidemiology of America, for all healthcare workers to get vaccinated against the flu, nationwide rates hover at 60-65 percent, and relatively few hospitals have enacted mandatory vaccination programs.

"Our findings suggest that inertia, rather than conscious objection or protest, is a major driver of low vaccination rates," Huang said. "We hope this finding motivates medical facilities to develop policies to ensure that the safety of patients comes first."

Link Between Delirium And Patient Isolation

Main Category: MRSA / Drug Resistance

Article Date: 14 Dec 2011 - 1:00 PST

A new study finds that patients who are moved into isolation during a hospital stay are nearly twice as likely to develop delirium, a potentially dangerous change in mental status that often affects hospital patients. Patients who began their stay in isolation were not at increased risk.

The study, published in the January issue of Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America, is the largest of its kind to examine the link between delirium and measures taken to prevent the spread of hard-to-treat infections such as MRSA. The measures, known as contact precautions, require patients to be isolated in their own room, and for healthcare personnel to wear masks, gowns, and other protective equipment. Some clinicians have been concerned that contact precautions may be disorienting to patients, making delirium more likely. Though delirium is generally a temporary condition, it can often adversely affect patient care. Symptoms include confusion, an inability to pay attention, and fluctuations in alertness.

A team of researchers led by Dr. Hannah Day of the University of Maryland School of Medicine examined two years of data from the university's 662-bed medical center. They found that patients who were placed on contact precautions at some point after admission to the hospital were 1.75 times more likely to develop delirium. However, patients on contact precautions starting at admission were no more likely to develop delirium. That finding, the researchers say, suggests that it may not be the precautions themselves causing delirium.

"Patients in our study who were placed on contact precautions later in their hospitalization were generally sicker than those who were on contact precautions from the outset," said Dr. Day. "So it's possible that the underlying illness rather than the precautions themselves is responsible for the association with delirium."

"Regardless of cause, we hope clinicians will view a move to isolation as a marker for increased risk of delirium and take appropriate precautions."

Dr. Day and her colleagues say patients on contact precautions should be educated about the reasons for and the goals of the intervention so they might be more comfortable with it. Clinicians should also take extra care to monitor medications and try not to interrupt patients' sleep patterns. In addition, isolation rooms should have clocks, calendars, and other orienting objects to help avoid sensory deprivation.

Researcher Studies The Globalization Of Sex Trafficking And The Organizations That Work To Stop It

Article Date: 14 Dec 2011 - 1:00 PST

In today's world, human trafficking is not an isolated problem, but a growing global issue. A Kansas State University professor is studying ways that anti-trafficking groups are fighting back.

"The focus of my research is not just to say how much sex trafficking is occurring, but how forms of it are changing," said Nadia Shapkina, assistant professor of sociology, who is looking at the geography, history and economic impact of trafficking. "The sex trade has been a global industry for a long time. But now, with the globalization of technology and transportation, it is becoming even more transnationalized."

One form of the sex trade that has evolved in recent years is sex tourism, which combines aspects of tourism with the purchase of sexual services, particularly of young women. About 95 percent of sex tourists are men from wealthy countries who come to tourist destinations - such as Greece, Thailand or Australia - for both entertainment and sex.

"Sex trafficking delivers women to customers, but sex tourism delivers customers to the place of consumption," Shapkina said. "Sex tourism becomes a very lucrative business. Technology, communication and transportation all allow that and they enable the trafficking of women as well."

Sex tourism operations are often led by skilled businessmen who know how to appeal and advertise to middle- and upper-class men with money and resources to travel and consume sexual services. Their messages have spread worldwide, Shapkina said, pointing to the United States, where multiple cases of labor and sex trafficking have been investigated.

"It doesn't necessarily mean that the market has increased, but it might mean that authorities have started detecting this criminal practice," Shapkina said. "It is hard to estimate the size of the sex trade because it is so underground. But what we can say is that it is very transnationalized and even the U.S. is affected by this negative aspect of globalization."

The globalization of human trafficking has also led to a rise in anti-trafficking activism. Shapkina is looking at how governments, international organizations, nongovernmental organizations and celebrity activists are collaborating to combat trafficking. She is mapping out organizations to understand what kind of resources they have, how successful they are and what they can achieve.

In the process, she has noticed challenges that many activist groups face. It is often difficult to coordinate actions across national borders because legal systems and cultures vary across countries. For instance, some countries such as Saudi Arabia penalize female victims of human trafficking, while countries such as Germany take a more humanistic approach by providing services for the victims.

Similarly, Shapkina is finding that many activist organizations turn to the government for help. Sometimes the governments respond and sometimes they don't, especially if the country has a strong sex tourism presence and governments benefit from the revenues from the sex trade.

Allegiances also play a role in a country's willingness to criminalize human trafficking. For instance, Turkey had no presence of active anti-trafficking organizations, but when the country wanted to join the European Union it began involving nonprofit organizations to work on the problem. A similar situation is happening in Ukraine as it tries to join the European Union and has to satisfy human rights and gender equality standard policies of the union.

"I have focused on Eastern Europe because the trafficking of women has become a problem in the region," said Shapkina, who is originally from Russia. "Many nongovernmental organizations have been forming in that area, and they want to focus on human trafficking. That is very new and we need to explain what is going on there."

Shapkina is also following human trafficking in the United States, where many initial anti-trafficking campaigns focused on foreign-born populations and immigrants as victims. That led to a realization of domestic exploitation, and prompted activists to focus on domestic trafficking, especially of minors.

"Clearly, the sex trade is a social problem, especially a gender inequality problem," Shapkina said. "This is what makes this trade possible, which involves the economic disempowerment of women. That's why we need to empower women economically and politically."

Shapkina recently gave a presentation about the global sex trade at the Gendered Commodity Chains: Bringing Households and Women into Global Commodity Chain Analysis international conference at Binghamton University, which is part of the State University of New York. An article based on the conference presentation will be published in 2012. Shapkina has also written a chapter about sex tourism in Ukraine. The chapter will be published in 2012 in the book "Sex Tourism in Ukraine: A Social Problem."

Prevention and Public Health Fund - Don't Approve Cuts, APHA Urges Lawmakers

The U.S. house of Representatives is being urged by the American Public Health Association (APHA) to reject a proposal that would significantly reduce the amount of funding the Prevention and Public Health Fund receives.

Alan Baker, interim executive director of APHA, explains:

"Dramatic cuts to the Prevention and Public Health Fund is a lose-lose solution. Moving the current health care system even farther downstream by repealing critically needed investments in prevention and public health programs would be absolutely devastating to the nation's health. It would also place a greater financial burden on an already strained system. This is a senseless and purely raw political moves."

The Prevention and Public Health Fund represents an unprecedented investment of mandatory funding for public health and prevention efforts. The fund backs attempts to promote early detection, prevention, and reduce the severity of chronic diseases.

In the U.S. each year chronic diseases account for 7 out of 10 deaths. The fund is allocated to ensure drinking-water is safe, protect Americans from infectious diseases and outbreaks of food-borne illnesses, and to increase capacity of state and local health department in communities throughout the United States.

Baker said:

"Today's proposed cuts would effectively pull the rug out from under local communities where we're already seeing critical public health funding at work. We call on the House to not let shortsighted political wrangling take precedence over improving Americans' health."

On December 15, an advocacy day co-sponsored by the American Public Health Association will be held on Capitol Hill in order to encourage members of Congress to protect the Prevention and Public Health Fund.

In addition, the proposal threatens to restrain a ruling by the U.S. Environmental Protection to considerably lower toxic air pollutants like mercury and soot discharged by incinerators and industrial boilers. According to APHA these crucial air quality standards must be finalized and would offer vitally important and long overdue public health protections.

Just 51% Of US Adults Married Today, Compared To 72% Fifty Years Ago

The proportion of American adults who are married today is the lowest ever, according to a new report published by Pew Research. Not only is marriage becoming progressively avoided, the authors added, but also people are waiting longer to tie the traditional knot. The average age for getting married is now 26.5 for females and 28.7 for males.

The researchers - D'Vera Cohn, Jeffrey Passel and Wendy Wang - who gathered data from the US Census, explained that if trends continue along their recent pattern, it will be very few years before the percentage of married adults is lower than single ones.

The institution of marriage is gradually giving way to: Cohabitation Single-person householdsOne-parent families (single parenthood)Young adults continuing to stay with their parents for longer (partly due to the current economic crisis)marriagestats

In just one year (2009 to 2010) the total number of weddings in America dropped by 5%. The authors said they did not look into the reasons for this, which may or may not be linked to the current economic climate.

Most other developed nations have also seen marriage declining. The long-term decline does not seem to be associated with any business or economic cycle. The percentage of adults who are married has been falling at about the same rate every year, regardless of whether there were periods of economic boom or bust.

In America, the steepest drops in marriage rates have been seen among younger adults - only 20% of Americans aged from 18 to 29 are married today; in 1960 the figure was nearly triple (59%). The average adult who gets married today, does so six years later than his/her counterparts of fifty years ago.

Today, 72% of adults have been married once or more ("ever-married"), compared to 85% fifty years ago.

marriageage

Almost 40% of adults in the USA today say marriage is becoming an archaic institution, the authors found. However, they also report that in 2010, approximately 61% of adults who have never been married would like to be one day.

marriageage

The decline in marriage has been slower among those with college degrees compared to less educated people. Part of the reason for people getting married at an older age today can be attributed to a much higher percentage of adults now going to college, and subsequently putting off such commitments until they have completed their academic qualifications.

Although divorce has been a contributory factor to the drop in the proportion of married adults today, this was more the case earlier on. Divorce rates have remained pretty stable over the last twenty years, while marriage continued to decline.

One just has to look the John B. Calhoun's mouse study to see ultimate outcome for humanity. Declining marriage, decreasing progeny, decreasing social interaction, increasing autism, pan-sexuality and hyper-sexuality among behavioral sinks. It is not that hard to see.

America is a "police state" and it's getting worse by the year.

No one should ever get married in a "police state", and you should NOT have children either.

Government should get out of the marriage bizniz altogether. It doesn't belong in our bedrooms and never did. Marriage should be an institution belonging to the Church, or simply a civil bargain between the individuals without any government 'licensing'.

I agree that not as many people are married today as 50 years ago. However, from my own personal situation my boyfriend and I would love to be married but with the economic crisis we are striving to just make it. We have been together for 10 years, since we were 14 and have our master degrees. Which was also on our to do list, along with securing a FT job before we would get married and have kids. Things don't always go as planned so that is te reason we ar not married yet. Although we would like to be, we do not want to go to the courthouse and get married. Thus, we must hope for the best, do what we can to make it in this economic crisis and hope for the best, so that one day we will be able to have our dream wedding.

God in all his kindness will eventually strike back at all this depravity, indulgence and sin. It is only a question of time!!

Marriage is an institution invented by men, to control women. As women become more financially independent, it becomes obsolete.

Pestered for a decade on divorce issues this gentleman decided to burn himself on the steps of the court house with gasoline. Here is his last statement. Courts did not apparently help his situation. Only the spouses have the knowledge to fix their problems, wash the divorce courts into the sea because I think they make things worse.

So God will 'strike back' for all the depravity, indulgence, & sin? Does that mean He's a Yankees fan?

Scientists have discovered a new signal that helps invading bacteria communicate but also helps targeted rice plants coordinate defensive attacks on the disease-causing invaders, a finding that could lead to new methods of combatting infection not just in plants, but in humans.

Findings from the study, conducted by a team of researchers led by a University of California, Davis, scientist, were reported in the journal /i>PLoS ONE and in the journal Discovery Medicine.

"Just as invading armies often use coded messages to coordinate attacks on their targets, so single-celled bacteria use biological signals to communicate when they attack plants and animals," said Pamela Ronald, a UC Davis professor of plant pathology and the lead researcher on the study. "Scientists have known this for 20 years, however results from our study reveal a type of bacterial signal that has never been described before."

UC Davis has a long history of tackling agricultural and environmental challenges related to rice production in the United States and around the world. Today, campus researchers are using molecular biology to better understand how to improve the hardiness and yield of this grain, which is a staple food for more than half of the world's population and an important model for plant research.

Up until now, scientists thought that two major groups of bacteria used two distinctly different types of communication codes, Ronald said. However Ax21, the small protein examined in this study, doesn't fit into either of those previously identified communication codes.

Ax21 is made inside the bacterial cell and processed to generate a shorter signal that is secreted outside the bacterium. This signal tips off other bacteria to assemble themselves into elaborate protective bunkers, called biofilms, which make the bacteria resistant to drying out and antibiotic treatment.

"Additionally, Ax21 triggers a change in the expression of nearly 500 bacterial genes, transforming the bacteria from fairly benign organisms into fierce invaders," Ronald said.

"In essence, through communication and communal living, the bacteria increase their chances of survival and proliferation," she said, noting that in rice, the bacteria multiply rapidly in the arteries that transport water, causing the plant to wither and die.

While most rice plants have little defense against the Ax21-mediated bacterial attack, some rice plants carry an immune receptor called XA21 that detects the Ax21 protein produced by the invading bacteria. XA21 belongs to a large class of immune receptors in plants and animals.

The importance of these receptors in immunity is reflected in the awarding of the 2011 Nobel Prize in physiology and medicine to researchers Bruce Beutler of The Scripps Research Institute in La Jolla and Jules Hoffman of the National Center of Scientific Research in Strasbourg, France, for their discoveries of similar receptors in animals.

The new study points out that the Ax21 signaling protein triggers the XA21 immune receptor to biologically alert the plant to launch a powerful defense response against the invading bacteria. The researchers also demonstrated that Ax21 is present in a human disease-causing bacterium that is known to infect hospital patients.

"This study demonstrates that bacteria communicate using private messages. However, plants can intercept these messages and gain a tactical advantage in the evolutionary battle," Ronald said. " It's a fascinating story."
