    Full text: A 21-year-old female with multiple granulomas an the right iris with concomitant therapy refractive panuveitis was referred to the Department of Ophthalmology to exclude an ocular malignancy. The patient had a history of minimal change glomerulonephritis and cutaneous granulomas at the age of six years that were successfully treated with cyclophosphamide. Her visual acuity initially already reduced to 30 % decreased rapidly to 'counting fingers'. A clinical work-up including chest x-ray, spiral computed tomography of the lungs and a detailed serological examination including angiotensin converting enzyme showed no evidence of infection or neoplasia. Planar scintigraphy 24 hours after administration of 185 MBq Gallium-67 citrate demonstrated an intense tracer accumulation in both lacrimal glands. Salivary gland uptake was normal and there was only a faint accumulation in the mediastinum interpreted as normal. A biopsy of the right iris revealed a granulomatous non caseating inflammation diagnosed as sarcoidosis. A systemic combination treatment with prednisolone and methotrexate for 4 months could not control the inflammation. After therapy was changed to cyclosporine the inflammation decreased and visual acuity decreased to 60 %. Neither a 'lambda sign' (characteristic uptake of Ga-67 in intrathoracic lymph nodes resembling the Greek letter lambda) nor a typical 'panda sign' (bilateral salivary and lacrimal gland uptake of Ga-67) commonly present in sarcoidosis were seen in our patient. This case demonstrates that in individual patients with sarcoidosis, lacrimal gland uptake of Ga-67 may be the only significant noninvasive finding. (author)

  2. Wicked Female Characters in Roddy Doyle’s “The Pram”: Revisiting Celtic and Polish Myths in the Context of Twenty-First Century Ireland

    Full Text Available “The Pram” is the only horror story in Roddy Doyle’s collection The Deportees and Other Stories (2007. It is also unique in terms of its approach to Ireland’s multicultural scene in the twenty-first century. Doyle turns the other side of the coin and introduces a migrant caretaker (Alina, who loses her mind due to her employees’ (the O’Reilly family ill-treatment. As a reaction to their scornful attitude, Alina becomes a murderer. Set in the context of twenty-first century Dublin, “The Pram” contains various references to Celtic and Polish mythological female figures (in particular, the Old Hag of Beara and Boginka, which strengthen the thrilling, mythical elements in the plot. This paper aims to examine the characters’ negative attitude towards migrants in Ireland in the light of the racist discourse present in the story. Also, I will focus on the story’s female characters and discuss the handicaps of being a female migrant in Ireland. The parallels between the mythical female figures and the protagonist Alina will be another point to be analyzed. The argument of this paper is that Doyle does not always portray the positive outcomes of a multicultural society. On the contrary, he conveys the perspective of the incoming migrant. “The Pram” stages the obstacles that a female outsider may experience in Ireland and her subsequent transformation as a result of the racism she encounters there.

  3. Effect of twenty minutes of aerobic exercise on in vivo platelet release in moderately trained females: radioimmunoassay of platelet factor 4 and beta-thromboglobulin

    Circulating blood platelets serve an important role in the physiological process of hemostasis. Physical exercise has been documented to result in alterations in many hemostatic parameters including platelet size, number and function. Most published research data support the hypotheses that both hemostasis and fibrinolysis become activated as a consequence of various levels of physical exercise. The purpose of this study was to determine the effect of twenty minutes aerobic exercise on platelet activation in vivo. Platelet activation in vivo is associated with the release of platelet granular contents. Platelet alpha granules contain two platelet specific proteins: platelet factor 4 (PF4) and beta-thromboglobulin (BTG). Elevated plasma levels of these proteins are a specific marker of in vivo platelet activation. Subjects were moderately trained female volunteers between the ages of 22 and 40 years. Subjects were exercised or twenty minutes on a bicycle ergometer at workloads that represented 65 to 75% of their functional capacity. Blood specimens were drawn within five minutes of exercise. Plasma samples from exercise and control subjects were assayed for PF4 and BTG using a sensitive competitive-binding radioimmunoassay procedure. The mean plasma levels of both proteins were significantly greater in the exercising subjects when compared with the non-exercising controls. Data from this study support the following research hypotheses: BTG plasma levels will be significantly higher in exercising subjects than in non-exercising controls, and PF4 plasma levels will be significantly higher in exercising subjects than in non-exercising controls

    Full Text Available This study analyzes how 12 recent (2000-2011 Newbery Medal-winning books represent gender. The study counts how many of the books’ characters represent progressive or traditional gender roles, how many male and female characters represent each character category (protagonist, antagonist, major, and minor, how many strong female characters are accepted or rejected by their peers, how many characters hold stereotypical gender beliefs about themselves or their peers, and how many works contain balanced feminist perspectives. The study finds equitable female representation, but the study also finds a bias toward traditional male stereotypes. The results indicate a general acceptance of strong female characters and a balanced representation of females, regardless of a historical fiction classification. These results suggest that characters in Newbery Medal-winning books represent gender more equally and less stereotypically compared to characters in works of earlier decades.

    This study aimed to realize a prospective follow-up of the injuries occurring in female and male football players involved in the highest league in the Grand-Duchy of Luxembourg. Data concerning anthropometric characteristics and football activities were gathered in 125 female and 243 male football players via questionnaires at the beginning of the study. Then, a follow-up of moderate to severe injuries (> 15 days of interruption in football practice) was performed throughout the season 2013-2014. Sixteen injuries (injury incidence = 0.7 injuries/1000 h of exposure) were observed in 13 female football players (10.4%). These injuries concerned mainly the knee (n = 7; 43.7%), with capsules and ligaments being the most often concerned tissues (n = 7; 43.7%). In male football players, 41 severe injuries (injury incidence = 0.6 injuries/1000 h of exposure) were observed in 36 players (14.8%). These injuries concerned mainly the thighs (n = 12; 29.3%) and the muscles and tendons were the most often concerned tissues (n = 18; 43.9%). Injuries in football are predominantly located at the lower limbs, particularly the knees in female football players. The predominant muscle and tendon lesions of the thighs occurring in males could reveal that physical preparation is insufficient or inadequate for a number of players. Regarding these results, it is necessary to implement an injury prevention strategy. The "FIFA 11+" programme could be used as the basic method, but should be personalized according to sex. The injury collection methodology could be optimized with the use of an electronic database, such as the Training and Injury Prevention Platform for Sports (TIPPS). Beside the systematic recording of injury data (as well as the training load) by the players or the medical staff, this system allows to share of important information between stakeholders, follow-up the players, provide risk factor warnings and increase the awareness of the injury problem.

  8. Twenty years of JHEP

    International Nuclear Information System (INIS)

    Amati, Daniele; Bonora, Loriano

    2017-01-01

    On July 1st of twenty years ago we launched the first issue of JHEP. It was a real challenge to try the adventure of a scientific journal thought and managed by scientists, independent of private or institutional publishers. The idea was that physicists who were performing the work, writing the papers, and refereeing those of their peers, could also edit them in an electronic format. Thus, at a limited cost which could be handled by academic or scientific institutions, giving open access to the published information, and avoiding the heavy burden at that time placed on our libraries. In order to avoid the failure that - as we well remember was predicted to us by publishing companies and institutions, we needed the active support of the scientific community. A support in collaborating to the scrutiny of papers and scientific policies but, mainly, in sending to us their good papers. We contacted in that sense several of our most active and renowned colleagues, restricting of course to our high energy physics field. We received many enthusiastic responses as can be specifically seen from the papers that appear in the first issues of the journal, as well as the respected names listed in the advisory and in the editorial boards featuring in the opening page of the first issue of JHEP attached to this letter. We were optimists, but perhaps not as much as to foresee the success of the journal, which, in his first 20 years, turned out to be one of the most (if not the most) prestigious one in our field. Success for which --- as first project chairman and executive editor - we must essentially thank the scientific community who supported JHEP by considering it ''their journal'', as was our intention from the start. In this occasion we would like to recall the important contribution of Marco Fabbrichesi who designed the software on which the journal is based, and the technical personnel who implemented it and made it work. It is our pleasure to mention

  10. Female infertility

    1984-01-01

    Infertility, defined as 1 year of unprotected intercourse without conception, is becoming of increasingly important medical concern. Fertility in both the male and the female is at its peak in the twenties. Many couples today have postponed marriage and/or childbearing into their 30s until careers are established, but at that point fertility may be diminished. The current epidemic of venereal disease has been associated with an increasing incidence of tubal scarring. In addition, the use of intrauterine devices (IUDs) and birth control pills for contraception have let to later problems with pelvic inflammatory disease (PID) and ovulation disturbances. The problem of infertility intensifies as the number of babies available for adoption decreases. Therefore, it is estimated that approximately 10-20% of couples will eventually seek medical attention for an infertility-related problem. Fortunately, marked improvements in the results of tubal surgery are concurrently occurring secondary to refinements in microsurgical techniques, and many medical alternatives to induce ovulation are being developed. The male factor causes infertility in 30-40 % of couples, and the female factor is responsible in approximately 50% of couples. No cause is found in 10-20% of couples. This chapter discusses the role of coordinated imaging in the diagnosis and therapy of infertility in the female

  11. Twenty-first century vaccines

    2011-01-01

    In the twentieth century, vaccination has been possibly the greatest revolution in health. Together with hygiene and antibiotics, vaccination led to the elimination of many childhood infectious diseases and contributed to the increase in disability-free life expectancy that in Western societies rose from 50 to 78–85 years (Crimmins, E. M. & Finch, C. E. 2006 Proc. Natl Acad. Sci. USA 103, 498–503; Kirkwood, T. B. 2008 Nat. Med 10, 1177–1185). In the twenty-first century, vaccination will be expected to eliminate the remaining childhood infectious diseases, such as meningococcal meningitis, respiratory syncytial virus, group A streptococcus, and will address the health challenges of this century such as those associated with ageing, antibiotic resistance, emerging infectious diseases and poverty. However, for this to happen, we need to increase the public trust in vaccination so that vaccines can be perceived as the best insurance against most diseases across all ages. PMID:21893537

  12. Deformation quantization: Twenty years after

    1998-01-01

    We first review the historical developments, both in physics and in mathematics, that preceded (and in some sense provided the background of) deformation quantization. Then we describe the birth of the latter theory and its evolution in the past twenty years, insisting on the main conceptual developments and keeping here as much as possible on the physical side. For the physical part the accent is put on its relations to, and relevance for, 'conventional' physics. For the mathematical part we concentrate on the questions of existence and equivalence, including most recent developments for general Poisson manifolds; we touch also noncommutative geometry and index theorems, and relations with group theory, including quantum groups. An extensive (though very incomplete) bibliography is appended and includes background mathematical literature

    1977-01-01

    The twentieth anniversary of an institution is an appropriate time to look back and to ask what has been achieved. It is also an appropriate time to look ahead and to ask what should be the mission for the future. How can the strengths of the International Atomic Energy Agency (IAEA) be best utilized, what new opportunities should be seized upon, and what challenges should the IAEA be prepared to meet in the next twenty years? Forward planning is a very necessary activity in today's world. There are so many demands on national or institutional resources that careful analysis of options is necessary to establish priorities and ultimately to provide for implementation. But such planning must be done carefully with full appreciation for the validity and sensitivity of the input assumptions and data. Furthermore, today's plan, while setting goals and directions, cannot be so inflexible that it cannot be responsive to ever-changing political, economic and technical constraints or opportunities. Thus in looking ahead, the plan must contain provisions for flexibility to provide for further modifications in the light of ever-changing knowledge, attitudes, and world conditions. The experience of the past five years in the energy field, and especially in nuclear energy, underscores this need. In looking ahead for the next twenty years, we are attempting to describe the International Atomic Energy Agency and its role through the twentieth century. In doing so, we are automatically laying the base for the Agency's work going into the twenty-first century. In short, we are trying to visualize a programme that can serve the coming generation and, in doing so, creating a base from which the needs of the succeeding generation can be met. This is a large order and the crystal ball is less than clear. (author)

    The first training simulator for nuclear power plant personnel in Germany was commissioned twenty-five years ago. The strategy of training by simulators was developed and pursued consistently and continuously in order to ensure sound training of nuclear power plant personnel. The present thirteen simulators cover a broad range of plants. A systematic training concept also helps to ensure a high level of competence and permanent qualification of plant personnel. The anniversary was marked by a festive event at which Erich K. Steiner read a paper on 'The Importance of Simulator Training', and Professor Dr. Adolf Birkhofer spoke about 'Nuclear Technology Education and Training'. (orig.)

    Progress in UV/EB curing during the past twenty five years is briefly reviewed. During this time developments in unique polymer chemistry, novel equipment design and the introduction of relevant educational programmes has enabled radiation curing to become an established technology with specific strengths in certain industries. Possible reasons for the emergence of the technology in these niche markets are discussed. Despite the worldwide recession, radiation curing is shown to be expanding at 5% per annum with the prospect of higher growth with improving economic conditions. (Author)

    Full Text Available We present the analysis of twenty human genomes to evaluate the prospects for identifying rare functional variants that contribute to a phenotype of interest. We sequenced at high coverage ten "case" genomes from individuals with severe hemophilia A and ten "control" genomes. We summarize the number of genetic variants emerging from a study of this magnitude, and provide a proof of concept for the identification of rare and highly-penetrant functional variants by confirming that the cause of hemophilia A is easily recognizable in this data set. We also show that the number of novel single nucleotide variants (SNVs discovered per genome seems to stabilize at about 144,000 new variants per genome, after the first 15 individuals have been sequenced. Finally, we find that, on average, each genome carries 165 homozygous protein-truncating or stop loss variants in genes representing a diverse set of pathways.

  5. Twenty five years of fundamental theory

    1980-01-01

    In reviewing the last twenty five years in fundamental physics theory it is stated that there has been no revolution in this field. In the absence of gravitation, Lorentz invariance remains a requirement on fundamental laws. Einstein's theory of gravitation inspires increasing conviction on the astronomical scale. Quantum theory remains the framework for all serious effort in microphysics, and quantum electrodynamics remains the model of a fully articulated microphysical theory, completely successful in its domain. However,a number of ideas have appeared, of great theoretical interest and some phenomenological success, which may well contribute to the next decisive step. Recent work on the following topics is mentioned; gravitational radiation, singularites, black body radiation from black holes, gauge and hidden symmetry in quantum electrodynamics, the renormalization of electromagnetic and weak interaction theory, non-Abelian gauge theories, magnetic monopoles as the most striking example of solitons, and supersymmetry.

    This final entry in the History of Human Space Exploration mini-series by Ben Evans continues with an in-depth look at the latter part of the 20th century and the start of the new millennium. Picking up where Partnership in Space left off, the story commemorating the evolution of manned space exploration unfolds in further detail. More than fifty years after Yuri Gagarin’s pioneering journey into space, Evans extends his overview of how that momentous voyage continued through the decades which followed. The Twenty-first Century in Space, the sixth book in the series, explores how the fledgling partnership between the United States and Russia in the 1990s gradually bore fruit and laid the groundwork for today’s International Space Station. The narrative follows the convergence of the Shuttle and Mir programs, together with standalone missions, including servicing the Hubble Space Telescope, many of whose technical and human lessons enabled the first efforts to build the ISS in orbit.

  7. Female condoms.

    Bounds, W

    1997-06-01

    Early versions of a female condom were available in the 1920s and 1960s, but they were little used and soon forgotten. It took the arrival of AIDS, and the urgent need for a wider range of female-controlled barrier techniques, to rekindle scientific interest in this method. In the 1980s, three groups in Europe and the USA began development of new female condom designs, comprising 'Femidom (Reality)', the 'Bikini Condom', and 'Women's Choice'. Apart from differences in their physical design, Femidom differs from the others in that it is made of a polyurethane membrane, which has several advantages over latex. Of the three, Femidom is the most advanced in terms of development and clinical testing, and it is the only one to have reached the marketing stage. Laboratory studies and clinical trials suggest that its contraceptive efficacy is similar to that documented for the male condom, though a direct comparison is not possible because no comparative clinical trials have, as yet, been undertaken. Reported 'typical-use' pregnancy rates range from 12.4 to 22.2% at 6 months of use in the USA and Latin America, respectively, while a study in the UK observed a rate of 15% at 12 months. As with all barrier methods, most failures appear to be associated with poor compliance or incorrect use. 'Perfect-use' pregnancy rates were substantially lower, indicating that Femidom can be very effective, if used consistently and correctly. Evidence for Femidom's effectiveness to protect against transmission of sexual disease-causing organisms, including HIV, is still very limited and based largely on laboratory studies. Whilst, in theory, the condom should confer reliable protection, its efficacy in clinical use will depend upon correct and consistent use and upon the product's ability to maintain an effective physical barrier throughout penetrative intercourse. In this respect, the results of recent and ongoing clinical studies are expected with much interest. How valuable Femidom will

    “The Twenty-five Maiden Ladies’ Tomb” is the collective burial site of the female workers who died in a ferry accident on their way to work in 1973. The fact that of the more than 70 passengers on board all 25 who died were unmarried young women, and the taboo in Taiwanese culture that shuns unmarried female ghosts, made the Tomb a fearsome place.

  9. Twenty years of immunocontraceptive research: lessons learned.

    Miller, Lowell A; Fagerstone, Kathleen A; Eckery, Douglas C

    2013-12-01

    The National Wildlife Research Center (NWRC) began immunocontraception vaccine research by testing porcine zona pellucida (PZP) on white-tailed deer (Odocoileus virginianus). Early PZP research demonstrated that PZP induced infertility; however, increased length of the rut was observed in PZP-treated deer. An alternative vaccine using a keyhole limpet hemocyanin-gonadotropin-releasing hormone (KLH-GnRH) conjugate formulated with modified Freund's adjuvant was developed at NWRC. Suppression of GnRH has reduced reproduction in both sexes but is most effective in females. This vaccine was effective in preventing contraception in female deer for several years after a prime and boost. Due to adverse side effects of Freund's adjuvant, NWRC developed a new adjuvant called AdjuVac, a mineral oil/surfactant adjuvant with the addition of Mycobacterium avium as an immunostimulant. The price of KLH prompted a search for a more economical hemocyanin carrier protein for the GnRH peptide. Blue protein, derived from the mollusk Concholepas concholepas, proved to be a successful option. Formulation improvements resulted in a vaccine that can be effective as a single injection for multiple years, now called GonaCon. GonaCon is registered with the Environmental Protection Agency (EPA) for use in white-tailed deer in urban/suburban areas and for wild horses (Equus caballus) and burros (Equus asinus). Future GonaCon applications may include reducing reproduction to manage populations of other wildlife species, such as prairie dogs (Cynomys ludovicianus) in urban areas and suppressing reproduction to reduce the spread of venereal diseases such as brucellosis. Research is being conducted to develop a GnRH vaccine used in combination with the rabies vaccine to control population growth in free-roaming dogs, with the secondary effect of managing the spread of rabies. The EPA would regulate all these uses. Research is also ongoing on a GnRH vaccine to delay the onset of adrenocortical

    Despite modern treatment approaches and a focus on community care, there remains a group of people who cannot easily be discharged from psychiatric hospital directly into the community. Twenty-four hour residential rehabilitation (a 'ward-in-a-house') is one model of care that has evolved in association with psychiatric hospital closure programmes. To determine the effects of 24 hour residential rehabilitation compared with standard treatment within a hospital setting. We searched the Cochrane Schizophrenia Group Trials Register (May 2002 and February 2004). We included all randomised or quasi-randomised trials that compared 24 hour residential rehabilitation with standard care for people with severe mental illness. Studies were reliably selected, quality assessed and data extracted. Data were excluded where more than 50% of participants in any group were lost to follow-up. For binary outcomes we calculated the relative risk and its 95% confidence interval. We identified and included one study with 22 participants with important methodological shortcomings and limitations of reporting. The two-year controlled study evaluated "new long stay patients" in a hostel ward in the UK. One outcome 'unable to manage in the placement' provided usable data (n=22, RR 7.0 CI 0.4 to 121.4). The trial reported that hostel ward residents developed superior domestic skills, used more facilities in the community and were more likely to engage in constructive activities than those in hospital - although usable numerical data were not reported. These potential advantages were not purchased at a price. The limited economic data was not good but the cost of providing 24 hour care did not seem clearly different from the standard care provided by the hospital - and it may have been less. From the single, small and ill-reported, included study, the hostel ward type of facility appeared cheaper and positively effective. Currently, the value of this way of supporting people - which could be

    In 1973, immediately following the Arab Oil Embargo, the Energy Resources Center, University of Illinois at Chicago initiated an innovative annual public service program called the Illinois Energy Conference. The objective was to provide a public forum each year to address an energy or environmental issue critical to the state, region and nation. Twenty years have passed since that inaugural program, and during that period we have covered a broad spectrum of issues including energy conservation nuclear power, Illinois coal, energy policy options, natural gas, alternative fuels, new energy technologies, utility deregulation and the National Energy Strategy

  13. Twenty years after the Chernobyl accident

    International Nuclear Information System (INIS)

    2006-01-01

    Full text: The April 1986 accident at the Chernobyl nuclear power plant remains a painful memory in the lives of the hundreds of thousands of people who were most affected by the accident. In addition to the emergency rescue workers who died, thousands of children contracted thyroid cancer, and thousands of other individuals will eventually die of other cancers caused by the release of radiation. Vast areas of cropland, forests, rivers and urban centres were contaminated by environmental fallout. Hundreds of thousands of people were evacuated from these affected areas - forced to leave behind their homes, possessions, and livelihoods - and resettled elsewhere, in a traumatic outcome that has had long-lasting psychological and social impacts. The commemoration of the Chernobyl tragedy is taking place in many forums this month - in Minsk, in Kiev and in other locations. At the IAEA, it might be said that we have been responding to the accident and its consequences for twenty years, in a number of ways: first, through a variety of programmes designed to help mitigate the environmental and health consequences of the accident; second, by analyzing the lessons of what went wrong to allow such an accident to occur at all; and third, by working to prevent any such accident from occurring in the future. Building a strong and effective global nuclear safety regime is a central objective of our work. This requires effective international cooperation. The explosions that destroyed the Unit 4 reactor core, and discharged its contents in a cloud of radionuclides, made painfully clear that the safety risks associated with nuclear and radiological activities extend beyond national borders. International cooperation on nuclear safety matters - sharing information, setting clear safety standards, assisting with safety upgrades, and reviewing operational performance - has therefore become a hallmark of IAEA activity, particularly at a time when we are witnessing an expansion of

  14. Female genital mutilation in Britain.

    Science.gov (United States)

    Black, J A; Debelle, G D

    1995-06-17

    The practice of female genital mutilation predates the founding of both Christianity and Islam. Though largely confined among Muslims, the operation is also practiced in some Christian communities in Africa such that female genital mutilation takes place in various forms in more than twenty African countries, Oman, Yemen, the United Arab Emirates, and by some Muslims in Malaysia and Indonesia. In recent decades, ethnic groups which practice female genital mutilation have immigrated to Britain. The main groups are from Eritrea, Ethiopia, Somalia, and Yemen. In their own countries, an estimated 80% of women have had the operation. Female genital mutilation has been illegal in Britain since 1985, but it is practiced illegally or children are sent abroad to undergo the operation typically at age 7-9 years. It is a form of child abuse which poses special problems. The authors review the history of female genital mutilation and describe its medical complications. Assuming that the size of the population in Britain of ethnic groups which practice or favor female genital mutilation remains more or less unchanged, adaptation and acculturation will probably cause the practice to die out within a few generations. Meanwhile, there is much to be done. A conspiracy of silence exists in medical circles as well as widespread ignorance. Moreover, none of a number of well-known obstetric and pediatric textbooks mentions female genital mutilation, while the National Society for the Prevention of Cruelty to Children has neither information nor instructional material. It is high time that the problem was more widely and openly discussed.

    Twenty-nail transverse melanonychia from hydroxyurea is a rare phenomenon, only reported four times previously. Here we describe a 51-year-old female who presented with 20-nail transverse melanonychia 3 months after initiating hydroxyurea therapy. Transverse melanonychia is a benign process but can cause patients significant distress, and thus is an entity with which dermatologists should recognize. We then review the cutaneous manifestations, differential diagnosis, and clinical considerations when evaluating patients with transverse melanonychia from hydroxyurea or other causes.

    Sacconaghi, Michele

    2006-01-01

    Aware that constituent support is essential to any educational endeavor, the AOL Time Warner Foundation (now the Time Warner Foundation), in conjunction with two respected national research firms, measured Americans' attitudes toward the implementation of twenty-first century skills. The foundation's national research survey was intended to explore public perceptions of the need for changes in the educational system, in school and after school, with respect to the teaching of twenty-first century skills. The author summarizes the findings of the survey, which were released by the foundation in June 2003. One thousand adults were surveyed by telephone, including African Americans, Latinos, teachers, and business executives. In general, the survey found that Americans believe today's students need a "basics-plus" education, meaning communication, technology, and critical thinking skills in addition to the traditional basics of reading, writing, and math. In fact, 92 percent of respondents stated that students today need different skills from those of ten to twenty years ago. Also, after-school programs were found to be an appropriate vehicle to teach these skills. Furthermore, the survey explored how well the public perceives schools to be preparing youth for the workforce and postsecondary education, which twenty-first century skills are seen as being taught effectively, and the level of need for after-school and summer programs. The survey results provide conclusive evidence of national support for basics-plus education. Thus, a clear opportunity exists to build momentum for a new model of education for the twenty-first century.

  1. Early twenty-first-century droughts during the warmest climate

    Directory of Open Access Journals (Sweden)

    Felix Kogan

    2016-01-01

    Full Text Available The first 13 years of the twenty-first century have begun with a series of widespread, long and intensive droughts around the world. Extreme and severe-to-extreme intensity droughts covered 2%–6% and 7%–16% of the world land, respectively, affecting environment, economies and humans. These droughts reduced agricultural production, leading to food shortages, human health deterioration, poverty, regional disturbances, population migration and death. This feature article is a travelogue of the twenty-first-century global and regional droughts during the warmest years of the past 100 years. These droughts were identified and monitored with the National Oceanic and Atmospheric Administration operational space technology, called vegetation health (VH, which has the longest period of observation and provides good data quality. The VH method was used for assessment of vegetation condition or health, including drought early detection and monitoring. The VH method is based on operational satellites data estimating both land surface greenness (NDVI and thermal conditions. The twenty-first-century droughts in the USA, Russia, Australia and Horn of Africa were intensive, long, covered large areas and caused huge losses in agricultural production, which affected food security and led to food riots in some countries. This research also investigates drought dynamics presenting no definite conclusion about drought intensification or/and expansion during the time of the warmest globe.

  2. Open Adoption Placement by Birth Mothers in Their Twenties.

    Science.gov (United States)

    Clutter, Lynn B

    The purpose of this study was to summarize birth mothers' descriptions of unplanned pregnancy experienced in their twenties and how open adoption influenced their lives. Naturalistic inquiry was used with purposive sampling from one agency and telephone interviews of women who experienced unplanned pregnancy in their twenties and relinquishment through open adoption. Recorded, transcribed, and deidentified interviews were analyzed for qualitative themes. Fifteen participants judiciously weighed the open adoption decision. Over half parented other children prior to placement. Most knew they could not have parented this child due to life stressors. Placement was a hard decision, but ongoing contact with birth child and adoptive family was valued. Open adoption processes made them stronger by being happy that their child experienced family life with greater opportunities than birth mothers could offer at the time. Summarized themes used the acronym COMMITTED: C-care deeply about what is best for the child, O-ongoing open adoption: good and hard, M-meeting together regularly, M-moving on in personal growth, accomplishments, and milestones, I-independence from previous stressors or crises, T-transitions, T-therapeutic support, E-emotions, D-depression giving way to deepened strength and personal direction. Open adoption is reinforced as a positive resolution of unintended pregnancy for birth mothers in their twenties.

  3. Female feticide in India.

    Science.gov (United States)

    Ahmad, Nehaluddin

    2010-01-01

    Women are murdered all over the world. But in India a most brutal form of killing females takes place regularly, even before they have the opportunity to be born. Female feticide--the selective abortion of female fetuses--is killing upwards of one million females in India annually with far-ranging and tragic consequences. In some areas, the sex ratio of females to males has dropped to less than 8000:1000. Females not only face inequality in this culture, they are even denied the right to be born. Why do so many families selectively abort baby daughters? In a word: economics. Aborting female fetuses is both practical and socially acceptable in India. Female feticide is driven by many factors, but primarily by the prospect of having to pay a dowry to the future bridegroom of a daughter. While sons offer security to their families in old age and can perform the rites for the souls of deceased parents and ancestors, daughters are perceived as a social and economic burden. Prenatal sex detection technologies have been misused, allowing the selective abortions of female offspring to proliferate. Legally, however, female feticide is a penal offence. Although female infanticide has long been committed in India, feticide is a relatively new practice, emerging concurrently with the advent of technological advancements in prenatal sex determination on a large scale in the 1990s. While abortion is legal in India, it is a crime to abort a pregnancy solely because the fetus is female. Strict laws and penalties are in place for violators. These laws, however, have not stemmed the tide of this abhorrent practice. This article will discuss the socio-legal conundrum female feticide presents, as well as the consequences of having too few women in Indian society.

    PREFACE The Twenty-First Workshop on Geothermal Reservoir Engineering was held at the Holiday Inn, Palo Alto on January 22-24, 1996. There were one-hundred fifty-five registered participants. Participants came from twenty foreign countries: Argentina, Austria, Canada, Costa Rica, El Salvador, France, Iceland, Indonesia, Italy, Japan, Mexico, The Netherlands, New Zealand, Nicaragua, the Philippines, Romania, Russia, Switzerland, Turkey and the UK. The performance of many geothermal reservoirs outside the United States was described in several of the papers. Professor Roland N. Horne opened the meeting and welcomed visitors. The key note speaker was Marshall Reed, who gave a brief overview of the Department of Energy's current plan. Sixty-six papers were presented in the technical sessions of the workshop. Technical papers were organized into twenty sessions concerning: reservoir assessment, modeling, geology/geochemistry, fracture modeling hot dry rock, geoscience, low enthalpy, injection, well testing, drilling, adsorption and stimulation. Session chairmen were major contributors to the workshop, and we thank: Ben Barker, Bobbie Bishop-Gollan, Tom Box, Jim Combs, John Counsil, Sabodh Garg, Malcolm Grant, Marcel0 Lippmann, Jim Lovekin, John Pritchett, Marshall Reed, Joel Renner, Subir Sanyal, Mike Shook, Alfred Truesdell and Ken Williamson. Jim Lovekin gave the post-dinner speech at the banquet and highlighted the exciting developments in the geothermal field which are taking place worldwide. The Workshop was organized by the Stanford Geothermal Program faculty, staff, and graduate students. We wish to thank our students who operated the audiovisual equipment. Shaun D.

    2005-12-01

    With infection once again a high priority for the UK National Health Service (NHS), the medical microbiology and infection-control services require increased technology resources and more multidisciplinary staff. Clinical care and health protection need a coordinated network of microbiology services working to consistent standards, provided locally by NHS Trusts and supported by the regional expertise and national reference laboratories of the new Health Protection Agency. Here, I outline my thoughts on the need for these new resources and the ways in which clinical microbiology services in the UK can best meet the demands of the twenty-first century.

    The development of the synchrotron, and later the storage ring, was based upon the electrical technology at the turn of this century, aided by the microwave radar techniques of World War II. This method of acceleration seems to have reached its limit. Even superconductivity is not likely to lead to devices that will satisfy physics needs into the twenty-first century. Unless a new principle for accelerating elementary particles is discovered soon, it is difficult to imagine that high-energy physics will continue to reach out to higher energies and luminosities.

  11. The Twenty-five Maiden Ladies’ Tomb and Predicaments of the Feminist Movement in Taiwan

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available “The Twenty-five Maiden Ladies’ Tomb” is the collective burial site of the female workers who died in a ferry accident on their way to work in 1973. The fact that of the more than 70 passengers on board all 25 who died were unmarried young women, and the taboo in Taiwanese culture that shuns unmarried female ghosts, made the Tomb a fearsome place. Feminists in Gaoxiong (高雄 had for some years wanted the city government to change the tomb’s public image. Their calls were not answered until the Gaoxiong mayor’s office finally allocated money to clean up the gravesite and, as part of the city’s plans to develop urban tourism, to remake it into the tourist-friendly “Memorial Park for Women Labourers”. Consequently, even though the tomb renovation seemed to indicate a triumph of the feminist endeavour, it was more a result of the Gaoxiong city government’s efforts towards culture-led urban revitalization.

  13. Strategies for Teaching Maritime Archaeology in the Twenty First Century

    Science.gov (United States)

    Staniforth, Mark

    2008-12-01

    Maritime archaeology is a multi-faceted discipline that requires both theoretical learning and practical skills training. In the past most universities have approached the teaching of maritime archaeology as a full-time on-campus activity designed for ‘traditional’ graduate students; primarily those in their early twenties who have recently come from full-time undergraduate study and who are able to study on-campus. The needs of mature-age and other students who work and live in different places (or countries) and therefore cannot attend lectures on a regular basis (or at all) have largely been ignored. This paper provides a case study in the teaching of maritime archaeology from Australia that, in addition to ‘traditional’ on-campus teaching, includes four main components: (1) learning field methods through field schools; (2) skills training through the AIMA/NAS avocational training program; (3) distance learning topics available through CD-ROM and using the Internet; and (4) practicums, internships and fellowships. The author argues that programs to teach maritime archaeology in the twenty first century need to be flexible and to address the diverse needs of students who do not fit the ‘traditional’ model. This involves collaborative partnerships with other universities as well as government underwater cultural heritage management agencies and museums, primarily through field schools, practicums and internships.

  14. Female urethral carcinoma

    Urethral carcinoma in 2 females has been treated with irradiation together with adjunct chemotherapy. In case 1, a 73-year-old female with squamous cell carcinoma was successfully treated with irradiation of 4,000 rad and peplomycin of 60 mg intravenously given. She has been free from the disease for the past 43 months. In case 2, a 61-year-old female with transitional cell carcinoma was initially treated with irradiation of 5,000 rad together with peplomycin 90 mg, which was followed by another 5,000 rad irradiation. The tumor recurred and the patient was operated on for cystourethrectomy and partial resection of the vagina. A further chemotherapy of cisplatin, peplomycin, and mitomycin C was instituted. She died of the tumor recurrence 23 months after the first visit to our clinic. Diagnosis and treatment modalities on the female urethral carcinoma are briefly discussed. (author)

  18. Increasing precipitation volatility in twenty-first-century California

    Science.gov (United States)

    Swain, Daniel L.; Langenbrunner, Baird; Neelin, J. David; Hall, Alex

    2018-05-01

    Mediterranean climate regimes are particularly susceptible to rapid shifts between drought and flood—of which, California's rapid transition from record multi-year dryness between 2012 and 2016 to extreme wetness during the 2016-2017 winter provides a dramatic example. Projected future changes in such dry-to-wet events, however, remain inadequately quantified, which we investigate here using the Community Earth System Model Large Ensemble of climate model simulations. Anthropogenic forcing is found to yield large twenty-first-century increases in the frequency of wet extremes, including a more than threefold increase in sub-seasonal events comparable to California's `Great Flood of 1862'. Smaller but statistically robust increases in dry extremes are also apparent. As a consequence, a 25% to 100% increase in extreme dry-to-wet precipitation events is projected, despite only modest changes in mean precipitation. Such hydrological cycle intensification would seriously challenge California's existing water storage, conveyance and flood control infrastructure.

  19. The Turn to Precarity in Twenty-First Century Fiction

    Directory of Open Access Journals (Sweden)

    Morrison Jago

    2014-01-01

    Full Text Available Recent years have seen several attempts by writers and critics to understand the changed sensibility in post-9/11 fiction through a variety of new -isms. This essay explores this cultural shift in a different way, finding a ‘turn to precarity’ in twenty-first century fiction characterised by a renewal of interest in the flow and foreclosure of affect, the resurgence of questions about vulnerability and our relationships to the other, and a heightened awareness of the social dynamics of seeing. The essay draws these tendencies together via the work of Judith Butler in Frames of War, in an analysis of Trezza Azzopardi’s quasi-biographical study of precarious life, Remember Me.

    2007-12-01

    Full Text Available This article explores some of the latest developments in the scholarship on race relations and nationalism that seek to address the impact of globalization and the changed geo-political relations of the first decade of the twenty-first century. New patterns of identification, some of which challenge existing group boundaries and others that reinforce them, can be seen to flow from the effects of global market changes and the political counter-movements against them. The impact of the “war on terrorism”, the limits of the utility of hard power, and the need for new mechanisms of inter-racial and inter-ethnic conflict resolution are evaluated to emphasize the complexity of these group relations in the new world disorder.

This project has positioned itself as a postcolonial critique, arguing that female sex tourism is a form of neocolonialism. It has also investigated the term romance tourism, where it has found that as a result of essentialist gender stereotyping, the female version of sex tourism has been titled ‘romance tourism’.

    Full Text Available Female androgenetic alopecia is the commonest cause of hair loss in women. It is characterized by a diffuse reduction in hair density over the crown and frontal scalp with retention of the frontal hairline and a characteristic pattern distribution in genetically predisposed women. Because of the uncertain relationship with the androgens Female Pattern Hair Loss (FPHL is the most preferred definition of the condition. This review has been focused on the clinical features, diagnosis and treatment alternatives of FPHL.

  7. Online Female Escort Advertisements

    2016-05-01

    Full Text Available Female escorts represent an occupational group that charges a fee for sex, which can be regarded as an extreme form of short-term mating. The present study examined if the fees charged by escorts are related to traits typically associated with female short-term mate value. A total of 2,925 advertisements for female escorts offering sexual services in the United States were examined, as a customized software program was used to download all the advertisements from an online escort directory. The advertisement content was coded, and relationships between advertised physical characteristics and the hourly rate charged by female escorts were examined. The analyses showed that higher fees were associated with female escorts who advertised a waist-to-hip ratio near 0.7, lower weight and body mass index, younger age, and photographic displays of breast and buttocks nudity. The findings provide evidence that evolutionarily relevant traits associated with female short-term mate value are systematically related to fees charged for sexual services.

    To strengthen the national framework for care of adolescents and women affected by female genital cutting (FGC) in Canada by providing health care professionals with: (1) information intended to strengthen their knowledge and understanding of the practice; (2) directions with regard to the legal issues related to the practice; (3) clinical guidelines for the management of obstetric and gynaecological care, including FGC related complications; and (4) guidance on the provision of culturally competent care to adolescents and women with FGC. Published literature was retrieved through searches of PubMed, CINAHL, and The Cochrane Library in September 2010 using appropriate controlled vocabulary (e.g., Circumcision, Female) and keywords (e.g., female genital mutilation, clitoridectomy, infibulation). We also searched Social Science Abstracts, Sociological Abstracts, Gender Studies Database, and ProQuest Dissertations and Theses in 2010 and 2011. There were no date or language restrictions. Searches were updated on a regular basis and incorporated in the guideline to December 2011. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. The quality of evidence in this document was rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care (Table 1). Summary Statements 1. Female genital cutting is internationally recognized as a harmful practice and a violation of girls' and women's rights to life, physical integrity, and health. (II-3) 2. The immediate and long-term health risks and complications of female genital cutting can be serious and life threatening. (II-3) 3. Female genital cutting continues to be practised in many countries, particularly in sub-Saharan Africa, Egypt, and Sudan. (II-3) 4. Global migration

  9. Male sexual harassment alters female social behaviour towards other females.

    Darden, Safi K; Watts, Lauren

    2012-04-23

    Male harassment of females to gain mating opportunities is a consequence of an evolutionary conflict of interest between the sexes over reproduction and is common among sexually reproducing species. Male Trinidadian guppies Poecilia reticulata spend a large proportion of their time harassing females for copulations and their presence in female social groups has been shown to disrupt female-female social networks and the propensity for females to develop social recognition based on familiarity. In this study, we investigate the behavioural mechanisms that may lead to this disruption of female sociality. Using two experiments, we test the hypothesis that male presence will directly affect social behaviours expressed by females towards other females in the population. In experiment one, we tested for an effect of male presence on female shoaling behaviour and found that, in the presence of a free-swimming male guppy, females spent shorter amounts of time with other females than when in the presence of a free-swimming female guppy. In experiment two, we tested for an effect of male presence on the incidence of aggressive behaviour among female guppies. When males were present in a shoal, females exhibited increased levels of overall aggression towards other females compared with female only shoals. Our work provides direct evidence that the presence of sexually harassing males alters female-female social behaviour, an effect that we expect will be recurrent across taxonomic groups.

    Female genital mutilation, also misleadingly known as female circumcision, is usually performed on girls ranging in from 1 week to puberty. Immediate physical complications include severe pain, shock, infection, bleeding, acute urinary infection, tetanus, and death. Longterm problems include chronic pain, difficulties with micturition and menstruation, pelvic infection leading to infertility, and prolonged and obstructed labor during childbirth. An estimated 80 million girls and women have undergone female genital mutilation. In Britain alone an estimated 10,000 girls are currently at risk. Religious, cultural, medical, and moral grounds rationalize the custom which is practiced primarily in sub-Saharan Africa, the Arab world, Malaysia, Indonesia, and among migrant populations in Western countries. According to WHO it is correlated with poverty, illiteracy, and the low status of women. Women who escape mutilation are not sought in marriage. WHO, the UN Population Fund, the UN Children's Fund, the International Planned Parenthood Federation, and the UN Convention on the Rights of the Child have issued declarations on the eradication of female genital mutilation. In Britain, local authorities have intervened to prevent parents from mutilating their daughters. In 1984, the Inter-African Committee Against Harmful Traditional Practices Affecting Women and Children was established to work toward eliminating female genital mutilation and other damaging customs. National committees in 26 African countries coordinate projects run by local people using theater, dance, music, and storytelling for communication. In Australia, Canada, Europe, and the US women have organized to prevent the practice among vulnerable migrants and refugees.

    20 cases of ectopic thyroid gland were detected out of 5,261 thyroid scintigraphy from 1973. Except for 1 case, all cases were female. Considering of thyroid function, 11 cases were euthyroid and rest of 9 cases were hypothyroid function. Clinical symptom of hypothyroid cases were mainly retarded linear growth and high value of serum TSH and in case of euthyroid cases were sublingual tumor and fullness or tightness in throat. Thyroid scintigraphy is very useful to diagnose the sublingual tumor whether it is ectopic thyroid gland or not. In case of congenital hypothyroidism children, ectopic thyroid gland causing hypothyroidism is definitely diagnosed by thyroid scintigraphy. (author)

    The passage of Title IX legislation in 1972 provided enormous opportunities for women to reap the benefits of sports participation. For most female athletes, sports participation is a positive experience, providing improved physical fitness, enhanced self-esteem, and better physical and mental health. Nonetheless, for a few female athletes, the desire for athletic success combined with the pressure to achieve a prescribed body weight may lead to the development of a triad of medical disorders including disordered eating, menstrual dysfunction, and low bone mineral density (BMD)--known collectively as the female athlete triad. Alone or in combination, the disorders of the triad can have a negative impact on health and impair athletic performance.

    The Russian RERTR Program started approximately 20 years ago. The USSR always supported principles and goals of the policy of nonproliferation and at the end of 70's the Soviet Government decided to create such national program. Twenty years is the sufficient time to estimate preliminary results of the realization of the program and its prospects on the future. After the first successes of the program, when the enrichment of uranium in fuel elements for foreign supplies was reduced from 80 % to 36 %, the realization of the program was suspended in connection with financial difficulties. But in the beginning of the 90's the Program has received a new pulse connected to the inclusion of Russian scientists and engineers in the international Program. Now basic directions in development of new kinds of fuel are development of works on fuel on a basis dioxide of uranium and development of fuel on a basis of U-Mo alloy. In the future to basic goals of the program the problem of the management of the spent nuclear fuel should be added. The management of HEU at the final stage of a fuel cycle becomes an important objective of the program, since the basic amount of HEU is concentrated in storage of SNF. (author)

  16. Nuclear energy into the twenty-first century

    Hammond, G.P.

    1996-01-01

    The historical development of the civil nuclear power generation industry is examined in the light of the need to meet conflicting energy-supply and environmental pressures over recent decades. It is suggested that fission (thermal and fast) reactors will dominate the market up to the period 2010-2030, with fusion being relegated to the latter part of the twenty-first century. A number of issues affecting the use of nuclear electricity generation in Western Europe are considered including its cost, industrial strategy needs, and the public acceptability of nuclear power. The contribution of nuclear power stations to achieving CO2 targets aimed at relieving global warming is discussed in the context of alternative strategies for sustainable development, including renewable energy sources and energy-efficiency measures. Trends in the generation of nuclear electricity from fission reactors are finally considered in terms of the main geopolitical groupings that make up the world in the mid-1990s. Several recent, but somewhat conflicting, forecasts of the role of nuclear power in the fuel mix to about 2020 are reviewed. It is argued that the only major expansion in generating capacity will take place on the Asia-Pacific Rim and not in the developing countries generally. Nevertheless, the global nuclear industry overall will continue to be dominated by a small number of large nuclear electricity generating countries; principally the USA, France and Japan. (UK)

  17. Twenty years on: Poverty and hardship in urban Fiji

    Jenny Bryant-Tokalau

    2012-09-01

    Full Text Available Through ‘official statistics’, academic and donor interpretations as well as the eyes of Suva residents, this paper presents an overview and case study of twenty years of growing poverty and hardship in the contemporary Pacific. Focusing on the past two decades, the paper notes how much, and yet so little, has changed for those attempting to make a living in the rapidly developing towns and cities. Changing interpretations of poverty and hardship are presented, moving from the ‘no such thing’ view, to simplification, and finally to an understanding that Pacific island countries, especially Fiji, are no longer an ‘extension’ of Australia and New Zealand, but independent nations actively trying to find solutions to their issues of economic, social and political hardship whilst facing challenges to traditional institutions and networks. Fiji is in some respects a very particular case as almost half of the population has limited access to secure land, but the very nature of that vulnerability to hardship and poverty holds useful lessons for wider analysis.

    2003-06-30

    The purpose of the Twenty Second Fungal Genetics Conference is to bring together scientists and students who are interested in genetic approaches to studying the biology of filamentous fungi. It is intended to stimulate thinking and discussion in an atmosphere that supports interactions between scientists at different levels and in different disciplines. Topics range from the basic to the applied. Filamentous fungi impact human affairs in many ways. In the environment they are the most important agents of decay and nutrient turnover. They are used extensively in the food industry for the production of food enzymes such as pectinase and food additives such as citric acid. They are used in the production of fermented foods such as alcoholic drinks, bread, cheese, and soy sauce. More than a dozen species of mushrooms are used as foods directly. Many of our most important antibiotics, such as penicillin, cyclosporin, and lovastatin, come from fungi. Fungi also have many negative impacts on human health and economics. Fungi are serious pathogens in immuno-compromised patients. Fungi are the single largest group of plant pathogens and thus a serious limit on crop productivity throughout the world. Many fungi are allergenic, and mold contamination of residences and commercial buildings is now recognized as a serious public health threat. As decomposers, fungi cause extensive damage to just about all natural and synthetic materials.

    Full Text Available Monoterpenes, the main constituents of essential oils, are known for their many biological activities. The present work studied the potential biological activity of twenty-seven monoterpenes, including monoterpene hydrocarbons and oxygenated ones, against seed germination and subsequent primary radicle growth of Raphanus sativus L. (radish and Lepidium sativum L. (garden cress, under laboratory conditions. The compounds, belonging to different chemical classes, showed different potency in affecting both parameters evaluated. The assayed compounds demonstrated a good inhibitory activity in a dose-dependent way. In general, radish seed is more sensitive than garden cress and its germination appeares more inhibited by alcohols; at the highest concentration tested, the more active substances were geraniol, borneol, (±-β-citronellol and α-terpineol. Geraniol and carvone inhibited, in a significant way, the germination of garden cress, at the highest concentration tested. Radicle elongation of two test species was inhibited mainly by alcohols and ketones. Carvone inhibited the radicle elongation of both seeds, at almost all concentrations assayed, while 1,8-cineole inhibited their radicle elongation at the lowest concentrations (10−5 M, 10−6 M.

    1990-01-01

    Modern synchrotrons and storage rings are based upon the electrical technology of the 1900s boosted by the microwave radar techniques of World War II. This method of acceleration now seems to be approaching its practical limit. It is high time that we seek a new physical acceleration mechanism to provide the higher energies and luminosities needed to continue particle physics beyond the machines now on the stocks. Twenty years is a short time in which to invent, develop, and construct such a device. Without it, high-energy physics may well come to an end. Particle physicists and astrophysicists are invited to join accelerator specialists in the hunt for this new principle. This report analyses the present limitations of colliders and explores some of the directions in which one might look to find a new principle. Chapters cover proton colliders, electron-positron colliders, linear colliders, and two-beam accelerators; transverse fields, wake-field and beat-wave accelerators, ferroelectric crystals, and acceleration in astrophysics.

  1. The twenty-first century challenges to sexuality and religion.

    Turner, Yolanda; Stayton, William

    2014-04-01

    Clergy and religious leaders are facing a wide variety of sexual needs and concerns within their faith communities. Conflicts over sexual issues are growing across the entire spectrum of religious denominations, and clerics remain ill prepared to deal with them. As religious communities work to remain influential in public policy debates, clergy and the institutions that train them need to be properly prepared for twenty-first century challenges that impact sexuality and religion. Clergy are often the first point of contact for sexual problems and concerns of their faith community members-complex issues centered on morals, spirituality, and ethics. Yet, there still exists a significant lack of sexual curricula in the programs that are educating our future religious leaders. The resulting paucity of knowledge leaves these leaders unprepared to address the needs and concerns of their congregants. However, with accurate, relevant human sexuality curricula integrated into theological formation programs, future leaders will be equipped to competently serve their constituencies. This paper provides a rationale for the need for such training, an overview of the faith- and theology-based history of a pilot training project, and a description of how the Christian faith and the social sciences intersect in a training pilot project's impetus and process.

    This article aims to provide a framework for analysing social opposition In Italy against the construction and management of electric power plants (nuclear and thermoelectric) and big electricity power lines in the past twenty years. First The author provide a history of social environmental opposition in the electric sector. This is followed by a typology of reason for opposition in terms of risk perception, which has been applied to about forty cases of social opposition against electric plants. This study an original experimental methodology which could also yield useful results when applied to other complex social phenomena. In the third phase of the study the author analyse the various roles of the social and institutional actors involved in the opposition, and the obstacles to future consensus building. The most interesting result of the study is the not only social but political nature opposition. This factor necessitates integration of the traditional individual risk perception approach with an approach which analyses political and social action of NGO's

  3. Male depression in females?

    2010-02-01

    Scientific evidence for a male-typed depression ("male depression") is still limited, but mainly supports this concept with respect to single externalizing symptoms or symptom clusters. In particular, studies on non-clinical populations including males and females are lacking. The present study aims at assessing general well-being, the risk and the symptoms of male depression dependent on biological sex and gender-role orientation on instrumental (masculine) and expressive (feminine) personality traits in an unselected community sample of males and females. Students (518 males, 500 females) of the Ludwig-Maximilians-University of Munich, Germany, were asked to participate in a "stress study" and complete the following self-report questionnaires: the WHO-5 Well-being Index [Bech, P., 1998. Quality of Life in the Psychiatric Patient. Mosby-Wolfe, London], the Gotland Scale for Male Depression [Walinder, J., Rutz, W., 2001. Male depression and suicide. International Clinical Psychopharmacology 16 (suppl 2), 21-24] and the German Extended Personal Attribute Questionnaire [Runge, T.E., Frey, D., Gollwitzer, P.M., et al., 1981. Masculine (instrumental) and feminine (expressive) traits. A comparison between students in the United States and West Germany. Journal of Cross-Cultural Psychology 12, 142-162]. General well-being of the students was significantly lower compared to population norms. Contrary to expectations, female students had a greater risk of male depression than male students (28.9% vs. 22.4%; p<0.05). Overall, prototypic depressive symptoms as well as externalizing symptoms were more pronounced in females. In the subgroup of those at risk for male depression, biological sex and kind of symptoms were unrelated. Principal component analyses revealed a similar symptom structure for males and females. Low scores on masculinity/instrumentality significantly predicted higher risk of male depression, independent of biological sex. The study sample is not

    2013-01-01

    Context: Female pattern hair loss (FPHL) also known as female androgenetic alopecia is a common condition afflicting millions of women that can be cosmetically disrupting. Prompt diagnosis and treatment are essential for obtaining optimal outcome. This review addresses the clinical presentation of female pattern hair loss, its differential diagnosis and treatment modalities. Evidence Acquisition: A) Diffuse thinning of the crown region with preservation of the frontal hairline (Ludwig’s type) B) The “Christmas tree pattern” where the thinning is wider in the frontal scalp giving the alopecic area a triangular shaped figure resembling a christmas tree. C) Thinning associated with bitemporal recession (Hamilton type). Generally, FPHL is not associated with elevated androgens. Less commonly females with FPHL may have other skin or general signs of hyperandrogenism such as hirsutism, acne, irregular menses, infertility, galactorrhea and insulin resistance. The most common endocrinological abnormality associated with FPHL is polycystic ovarian syndrome (PCOS). Results: The most important diseases to consider in the differential diagnosis of FPHL include Chronic Telogen Effluvium (CTE), Permanent Alopecia after Chemotherapy (PAC), Alopecia Areata Incognito (AAI) and Frontal Fibrosing Alopecia (FFA). This review describes criteria for distinguishing these conditions from FPHL. Conclusions: The only approved treatment for FPHL, which is 2% topical Minoxidil, should be applied at the dosage of 1ml twice day for a minimum period of 12 months. This review will discuss off-label alternative modalities of treatment including 5-alfa reductase inhibitors, antiandrogens, estrogens, prostaglandin analogs, lasers, light treatments and hair transplantation.

    Kazis, Keren; Iglesias, Elba

    2003-02-01

    The female athlete triad is a syndrome consisting of disordered eating, amenorrhea, and osteoporosis. The syndrome is increasing in prevalence as more women are participating in sports at a competitive level. Behaviors such as intense exercise or disordered eating patterns can lead to dysregulation of the hypothalamic-pituitarian-ovarian (HPO) axis, resulting in amenorrhea. Hypothalamic amenorrhea can lead to osteoporosis and increased fracture risk. Adolescents may particularly be at risk because it is during this crucial time that females attain their peak bone mass. Prevention of the female athlete triad through education and identification of athletes at risk may decrease the incidence of long-term deleterious consequences. Treatment of the female athlete triad is initially aimed at increasing caloric intake and decreasing physical activity until there is resumption of normal menses. Treatment of decreased bone mineral density and osteoporosis in the adolescent population, however, is controversial, with new treatment modalities currently being investigated in order to aid in the management of this disorder.

    The failure of central planning in the totalitarian systems of the USSR and its satellites adversely affected not only the economy and social relations but also the population health. While in the countries with established democracy (DEM) the general health and the life expectancy (LE) steadily improved, in countries declaring socialism (SOC) the LE was stagnant and in the USSR even decreased. Dramatic changes in Russia after the demise of Soviet Union resulted in an extraordinary destabilization of LE that reached a minimum in 1994. Remarkably, even twenty years after the breakdown of the Iron Curtain there persists a gap in the general health between the DEM and the SOC regions of Europe. Within the territory of the former Soviet influence there are additional differences in LE: Central Europe is much better off than Russia and its neighbours. Main cause of relatively high mortality in the post totalitarian Europe is the cardiovascular disease (CVD). Among females about 80% difference in LE between DEM and SOC countries is related to premature CVD mortality. In SOC males compared to DEM, about 50% of the higher mortality is caused by CVD, 20% is related to external factors (trauma, suicide) and 10% is oncologic disorders. The main suggested cause of such excess mortality, besides a low socioeconomic level and limited funding for health care, is an improper life style: alcoholism, smoking and inadequate intake of protective nutrients. Alcoholism, especially binge drinking is a prominent factor in Russia, Belarus, Ukraine and in the Baltic Republics (Fig. 6, Tab. 4, Ref. 20).

    2012-01-01

    Full Text Available Introduction. Advances in endourology have greatly reduced indications to open surgery in the treatment of staghorn kidney stones. Nevertheless in our experience, open surgery still represents the treatment of choice in rare cases. Case Report. A 71-year-old morbidly obese female patient complaining about occasional left flank pain, and recurrent cystitis for many years, presented bilateral staghorn kidney stones. Comorbidities were obesity (BMI 36.2, hypertension, type II diabetes, and chronic obstructive pulmunary disease (COPD hyperlipidemia. Due to these comorbidities, endoscopic and laparoscopic approaches were not indicated. We offered the patient staged open anatrophic nephrolithotomy. Results. Operative time was 180 minutes. Blood loss was 500 cc. requiring one unit of packed red blood cells. Hospital stay was 7 days. The renal function was unaffected based on preoperative and postoperative serum creatinine levels. Stone-free status of the left kidney was confirmed after surgery with CT scan. Conclusions. Open surgery can represent a valid alterative in the treatment of staghorn kidney stones of very selected cases. A discussion of the current indications in the twenty-first century is presented.

  15. Twenty years of operation of Ljubljana's TRIGA Mark II reactor

    1986-01-01

    Twenty years have now passed since the start of the TRIGA Mark II reactor in Ljubljana. The reactor was critical on May 31, 1966. The total energy produced until the end of May 1986 was 14.048 MWh or 585 MWd. For the first 14 years (until 1981) the yearly energy produced was about 600 MWh, since 1981 the yearly energy produced was 1000 MWh when a routine radioactive isotopes production started for medical use as well as other industrial applications, such as doping and irradiation with fast neutrons of silicon monocrystals, production of level indicators (irradiated cobalt wire), production of radioactive iridium for gamma-radiography, leak detection in pipes by sodium, etc. Besides these, applied research around the reactor is being conducted in the following main fields, where- many unique methods have been developed or have found their way into the local industry or hospitals: neutron radiography, neutron induced auto-radiography using solid state nuclear track detectors, nondestructive methods for assessment of nuclear burn-up, neutron dosimetry, calculation of core burn-up for the optimal in-core fuel management strategy. The solvent extraction method was developed for the everyday production of 99m Tc, which is the most widely used radionuclide in diagnostic nuclear medicine. The methods were developed for the production of the following isotopes: 18 F, 85m Kr, 24 Na, 82 Br, 64 Zn, 125 I. Neutron activation analysis represents one of the major usages for the TRIGA reactor. Basic research is being conducted in the following main fields: solid state physics (elastic and inelastic scattering of the neutrons), neutron dosimetry, neutron radiography, reactor physics and neutron activation analysis. The reactor is used very extensively as a main instrument in the Reactor Training Centre in Ljubljana where manpower training for our nuclear power plant and other organisations has been performed. Although the reactor was designed very carefully in order to be used for

  16. Twenty new ISO standards on dosimetry for radiation processing

    International Nuclear Information System (INIS)

    Farrar IV, H.

    2000-01-01

    Twenty standards on essentially all aspects of dosimetry for radiation processing were published as new ISO standards in December 1998. The standards are based on 20 standard practices and guides developed over the past 14 years by Subcommittee E10.01 of the American Society for Testing and Materials (ASTM). The transformation to ISO standards using the 'fast track' process under ISO Technical Committee 85 (ISO/TC85) commenced in 1995 and resulted in some overlap of technical information between three of the new standards and the existing ISO Standard 11137 Sterilization of health care products - Requirements for validation and routine control - Radiation sterilization. Although the technical information in these four standards was consistent, compromise wording in the scopes of the three new ISO standards to establish precedence for use were adopted. Two of the new ISO standards are specifically for food irradiation applications, but the majority apply to all forms of gamma, X-ray, and electron beam radiation processing, including dosimetry for sterilization of health care products and the radiation processing of fruit, vegetables, meats, spices, processed foods, plastics, inks, medical wastes, and paper. Most of the standards provide exact procedures for using individual dosimetry systems or for characterizing various types of irradiation facilities, but one covers the selection and calibration of dosimetry systems, and another covers the treatment of uncertainties using the new ISO Type A and Type B evaluations. Unfortunately, nine of the 20 standards just adopted by the ISO are not the most recent versions of these standards and are therefore already out of date. To help solve this problem, efforts are being made to develop procedures to coordinate the ASTM and ISO development and revision processes for these and future ASTM-originating dosimetry standards. In the meantime, an additional four dosimetry standards have recently been published by the ASTM but have

    2017-07-03

    Twenty-five years ago this month, Thomas Gold published a seminal manuscript suggesting the presence of a "deep, hot biosphere" in the Earth's crust. Since this publication, a considerable amount of attention has been given to the study of deep biospheres, their role in geochemical cycles, and their potential to inform on the origin of life and its potential outside of Earth. Overwhelming evidence now supports the presence of a deep biosphere ubiquitously distributed on Earth in both terrestrial and marine settings. Furthermore, it has become apparent that much of this life is dependent on lithogenically sourced high-energy compounds to sustain productivity. A vast diversity of uncultivated microorganisms has been detected in subsurface environments, and we show that H 2 , CH 4 , and CO feature prominently in many of their predicted metabolisms. Despite 25 years of intense study, key questions remain on life in the deep subsurface, including whether it is endemic and the extent of its involvement in the anaerobic formation and degradation of hydrocarbons. Emergent data from cultivation and next-generation sequencing approaches continue to provide promising new hints to answer these questions. As Gold suggested, and as has become increasingly evident, to better understand the subsurface is critical to further understanding the Earth, life, the evolution of life, and the potential for life elsewhere. To this end, we suggest the need to develop a robust network of interdisciplinary scientists and accessible field sites for long-term monitoring of the Earth's subsurface in the form of a deep subsurface microbiome initiative.

    2012-07-12

    Los Alamos National Laboratory (the Laboratory) is the nation's premier national security science laboratory. Its mission is to develop and apply science and technology to ensure the safety, security, and reliability of the United States (U.S.) nuclear stockpile; reduce the threat of weapons of mass destruction, proliferation, and terrorism; and solve national problems in defense, energy, and the environment. The fiscal year (FY) 2013-2037 Twenty-Five Year Site Plan (TYSP) is a vital component for planning to meet the National Nuclear Security Administration (NNSA) commitment to ensure the U.S. has a safe, secure, and reliable nuclear deterrent. The Laboratory also uses the TYSP as an integrated planning tool to guide development of an efficient and responsive infrastructure that effectively supports the Laboratory's missions and workforce. Emphasizing the Laboratory's core capabilities, this TYSP reflects the Laboratory's role as a prominent contributor to NNSA missions through its programs and campaigns. The Laboratory is aligned with Nuclear Security Enterprise (NSE) modernization activities outlined in the NNSA Strategic Plan (May 2011) which include: (1) ensuring laboratory plutonium space effectively supports pit manufacturing and enterprise-wide special nuclear materials consolidation; (2) constructing the Chemistry and Metallurgy Research Replacement Nuclear Facility (CMRR-NF); (3) establishing shared user facilities to more cost effectively manage high-value, experimental, computational and production capabilities; and (4) modernizing enduring facilities while reducing the excess facility footprint. Th is TYSP is viewed by the Laboratory as a vital planning tool to develop an effi cient and responsive infrastructure. Long range facility and infrastructure development planning are critical to assure sustainment and modernization. Out-year re-investment is essential for sustaining existing facilities, and will be re-evaluated on an annual

  19. Understanding Contamination; Twenty Years of Simulating Radiological Contamination

    2012-02-01

    A wide variety of simulated contamination methods have been developed by researchers to reproducibly test radiological decontamination methods. Some twenty years ago a method of non-radioactive contamination simulation was proposed at the Idaho National Laboratory (INL) that mimicked the character of radioactive cesium and zirconium contamination on stainless steel. It involved baking the contamination into the surface of the stainless steel in order to 'fix' it into a tenacious, tightly bound oxide layer. This type of contamination was particularly applicable to nuclear processing facilities (and nuclear reactors) where oxide growth and exchange of radioactive materials within the oxide layer became the predominant model for material/contaminant interaction. Additional simulation methods and their empirically derived basis (from a nuclear fuel reprocessing facility) are discussed. In the last ten years the INL, working with the Defense Advanced Research Projects Agency (DARPA) and the National Homeland Security Research Center (NHSRC), has continued to develop contamination simulation methodologies. The most notable of these newer methodologies was developed to compare the efficacy of different decontamination technologies against radiological dispersal device (RDD, 'dirty bomb') type of contamination. There are many different scenarios for how RDD contamination may be spread, but the most commonly used one at the INL involves the dispersal of an aqueous solution containing radioactive Cs-137. This method was chosen during the DARPA projects and has continued through the NHSRC series of decontamination trials and also gives a tenacious 'fixed' contamination. Much has been learned about the interaction of cesium contamination with building materials, particularly concrete, throughout these tests. The effects of porosity, cation-exchange capacity of the material and the amount of dirt and debris on the surface are very important factors

    Hypertension is the most common cardiovascular disorder affecting more males in younger age groups; in the age group of 45-64, it is equally frequent in both genders, it is more common in elderly females. Blood pressure increases more in females around the menopause. Use of hormonal replacement therapy is not associated with an BP increase but, because of increased risk of coronary events, stroke, and thromboembolic events, HRT is not re-commended in CVD prevention. There is a similar decrease in BP by antihypertensive drugs in both genders as well as benefit from antihypertensive treatment. Women report about a double rate of adverse events of antihypertensive drugs. Oral contraception use is associated with a mild BP increase in most women and development of overt hypertension in about 5 %. Pre-eclampsia is associated with increased risk of developing CVD later in life (more frequent development of hypertension, myocardial infarction, and stroke).

    We studied the relationship between nutritional reserves and blood-feeding and sugar-feeding of Anopheles freeborni (Diptera: Culicidae) females in the field. In particular we determined whether (1) females feed on nectar before maturing eggs and initiating host-seeking and (2) the energy reserves of host-seeking females differ from those of non-fed resting females. Twenty-three percent of host-seeking females and 94 percent of gravid females were positive for nectar sugars (containing > 20 micrograms of fructose) versus 55 percent of empty (no blood or eggs) females collected in the morning and 36 percent of empty females collected in the evening. In addition, gravid females contained significantly more calories of nectar than empty, blood-fed, or partially blood-fed females collected in the morning. When the energy reserves of host-seeking and resting females were compared, no differences were found in lipid, trehalose, or glycogen. However, empty females collected in the evening contained more glycogen than empty females collected in the morning. We conclude that gravid females frequently feed on nectar and that fructose is metabolized into glycogen during the day.

    Full Text Available Olympic weightlifting movements and their variations are believed to be among the most effective ways to improve power, strength, and speed in athletes. This study investigated the effects of two Olympic weightlifting variations (hang cleans and hang snatches, on power (vertical jump height, strength (1RM back squat, and speed (40-yard sprint in female collegiate athletes. 23 NCAA Division I female athletes were randomly assigned to either a hang clean group or hang snatch group. Athletes participated in two workout sessions a week for six weeks, performing either hang cleans or hang snatches for five sets of three repetitions with a load of 80-85% 1RM, concurrent with their existing, season-specific, resistance training program. Vertical jump height, 1RM back squat, and 40-yard sprint all had a significant, positive improvement from pre-training to post-training in both groups (p≤0.01. However, when comparing the gain scores between groups, there was no significant difference between the hang clean and hang snatch groups for any of the three dependent variables (i.e., vertical jump height, p=0.46; 1RM back squat, p=0.20; and 40-yard sprint, p=0.46. Short-term training emphasizing hang cleans or hang snatches produced similar improvements in power, strength, and speed in female collegiate athletes. This provides strength and conditioning professionals with two viable programmatic options in athletic-based exercises to improve power, strength, and speed.

    Full Text Available Objective: Myelopathy is used to describe any neurologic deficit related to the spinal cord. Determining the etiology is important for detecting emergency situations and treating the cause. Materials and Methods: We evaluated 28 patients who were diagnosed as having and treated for myelopathy between January 2014 and January 2015 in our hospital. The clinical and laboratory findings of the patients and their response to treatment were assessed. Results: Of the 28 patients, 16 were male and 12 were female, the mean age was 48 years (range, 22-77 years. The most common initial symptoms were sensorial deficits and motor weakness. Demyelinating diseases were the most common diseases and multiple sclerosis was the most frequent etiology among demiyelinating diseases. Cervical spinal cord was the most frequent region involved in myelopathy episodes which was detected by magnetic resonance imaging on T2W images. We observed clinical improvement in 15 of the 20 patients who were treated with corticosteroids. In addition, vitamin B12 treatment led to clinical improvement in two patients who were diagnosed as having subacute combined degeneration. Conclusion: The diagnosis and etiology of myelopathy and identification of rare conditions that require emergency surgery or interventional treatments are of utmost importance

    This study examined trail use among 857 trail users on 21 trails in Michigan from 2008 to 2011 using a valid and reliable intercept survey. Most of the 857 participants traveled to the trail from their home (92.6%), lived within 15 min of the trails (74.8%), and used active transport to travel to the trails 69.7%. The odds of active transport to the trails were greater among those who had not graduated high school (OR=3.49; 95% CI=1.02, 11.99) and high school graduates (OR=7.432; 95% CI=2.02, 27.30) compared to college graduates. Whites and adults also had greater odds of active transport than non-Whites (OR=3.160, 95% CI: 1.65, 6.05), and older adults (OR=1.75; 95% CI: 1.20, 2.54). The majority of respondents (89.7%) reported using trails for recreational purposes. A significantly greater proportion of females (73.3%) compared to males (64.7%) reported using the trail with others. The findings from this study might enable health and parks and recreation professionals to better promote physical activity on trails. Copyright © 2013 Elsevier Inc. All rights reserved.

    Abstract Elevated blood pressure (BP) is frequently diagnosed in very elderly hospitalized patients. Accurate diagnosis of hypertension is challenging in the hospital environment, due to the “white coat effect,” and both overtreatment and undertreatment can adversely affect clinical outcome. Twenty-four-hour ambulatory blood pressure monitoring (ABPM) has the potential to avoid the “white coat effect” and accurately guide the management of hypertension. However, effects of the hospital environment on ABPM are unknown in the very elderly. We set out to enroll 45 patients, age ≥70 years, with elevated conventional BP during hospitalization in this observational study. It was prespecified by protocol to assess initially the difference between 24-hour BP during hospital-admission and home follow-up. Subsequent analysis should investigate the change in anxiety (Hospital Anxiety and Depression Scale-A [HADS-A]) after discharge, the correlation with change in 24-hour BP after discharge, and the prevalence of orthostatic hypertension. Thirty-one patients were included in the final analysis (age 83.5 ± 4.4 years; 71% female). Twenty-four-hour BP decreased significantly after hospital discharge (systolic from 133.5 ± 15.6 to 126.2 ± 14.4 mm Hg [millimeter of mercury], P = .008; diastolic from 71.0 ± 9.0 to 68.3 ± 8.6 mm Hg, P = .046). Anxiety level (HADS-A) decreased significantly after discharge, from 7.5 (interquartile range [IQR]: 4.0–13.8) to 5.0 (IQR: 4.0–8.0, P = .012). The change in anxiety was a predictor of change in systolic BP after discharge (F[1,20] = 5.9, P = .025). Sixty-one percent of the patients had significant orthostatic hypotension during hospital stay. In conclusion, 24-hour BP in very elderly patients is lower in the home environment than during hospitalization. This phenomenon seems to be directly linked to a lower anxiety-level at home. Reassessing hypertension at home may decrease the

    2010-01-01

    Background: Sub-fertility is inability to ensure child bearing when it is wanted. Prevalence of sub-fertility in industrialised countries has been quoted as 20%, and seems to be on the rise. Traditional way to assess the uterine cavity, tubal structure and tubal patency was hysterosalpingography but it has now been largely superseded by laparoscopy and hysteroscopy. The objective of this study was to highlight the role of laparoscopy in establishing diagnosis of female infertility. Methods: This descriptive study was conducted in Gynaecology Unit of Liaquat University of Medical Health Sciences, Hyderabad, Pakistan from August 28, 2000 to July 1, 2001. Total 200 sub-fertile patients attended the gynaecology OPD. Out of these 30 patients were selected for laparoscopy and dye test who were suspected cases of endometriosis, abnormal HSG and unexplained infertility. Those patients who had medical disorders and contraindication for laparoscopy were excluded from study. Detailed history of every patient was recorded on a proforma and physical examination was performed. Laparoscopy was scheduled in proliferative phase of menstrual cycle. Data were analysed using SPSS 11. Frequency and percentages were calculated to describe the results. Results: Out of 200 sub-fertile patients total 30 patients were selected for laparoscopy. Twenty (66%) patients were in primary infertility group while 10 (33%) patients were in secondary infertility group. Eleven (55%) patients of primary infertility belong to age group of 18-25 years while 6(60%) patients of secondary infertility belong to age group of 26- 33 years. Mean duration of sub fertility at time of presentation in primary infertility group was 1.95 years while in secondary infertility was 2.70 years. In primary infertility group main associated symptoms were dysmenorrhoeal in 8 (40%), irregular cycles 5 (25%), and dyspareunia in 4 (20%). In secondary infertility group 3 (30%) patients had dysmenorrhoeal and dyspareunia while 2

    Under the German presidency, the European Council adopted a program of climate protection and energy policy on March 9, 2007. It contains these 3 objectives: (1) By 2020, greenhouse gas emissions in the EU will be reduced by at least 20 percent from their 1990 level. (2) The share of renewable energies in primary energy consumption in the EU will be raised to 20 percent by 2020. (3) To enhance energy efficiency, energy consumption in the EU is to be reduced by 20 percent relative to the forecasts for 2020. The reason given by the European Council for the ambitious energy efficiency goal is its conviction that, in addition to the considerable increase in renewables, a major improvement in energy efficiency will enhance the security of energy supply, attenuate the forecast rise in energy prices, and diminish greenhouse gas emissions. Nuclear power is mentioned only in passing and as a topic for national decisionmaking, which is absolutely unsatisfactory in the light of what nuclear power currently is, and could go on, contributing to the security of supply, the climate protection, and reasonably priced electricity supply. On the whole, the package of energy and environmental policy measures devised by the European Council may be termed ambitious. (orig.)

    Describe gender-based violence by intimate partners against female nurses in a sample of nurses in Andalucia, Spain. Descriptive transversal study. Hospitals and primary health care districts in Andalucia. Six hundred and twenty-two female nurses that work as nurses in the eight provinces in Andalucia (Spain). Social-demographic characteristics and presence of abuse (psychological, physical and sexual). 78.5% of the nurses were married or with a regular partner and had the economic income based on both salaries; 71.1% had a child or an elderly dependent person. It was proved that there can be a statistical association between abuse and: marital status; life together; familiar economic support and children and/or dependent elderly person. The average age was 42.5±8.1 years old (22-62 years) and presented statistical age differences comparing both groups: abused (average 44 years) and non-abused (average 41.8 years). Between the married couples studied, 21.7% of them belong to the social class I and 16.9% to the social class II. Between all studied nurses, 33.0% suffered abuse, among which 75.1% were psychologically abused. Of all the abuse cases 60% were less severe and 40% more serious. It was confirmed the presence of intimate partner violence (IPV) against nurses, which was predominantly psychological abuse, but others classes of abuse were present too.

    2013-01-01

    Introduction About 45% of women suffer from some form of sexual dysfunction. Despite its high prevalence, there are few studies that have systematically evaluated sex therapy in comparison with other interventions. Objective Review randomized clinical trials that present psychotherapeutic interventions for female sexual dysfunctions. Method Through a search in three databases (Medline, Web of Science and PsycInfo), 1419 references were found. After an analysis of the abstracts, twenty-seven articles met the inclusion criteria and composed this review. Results Sex therapy, as proposed by Masters and Johnson and Heiman and LoPiccolo, is still the most commonly used form of therapy for sexual dysfunctions; although it has shown results, the results do not consistently support that this is the best alternative in the treatment of sexual dysfunctions. Conclusion There is a lack of systematic study of many female sexual dysfunctions. Orgasmic disorder and sexual pain (vaginismus and dyspaurenia) are the most extensively studied disorders and those in which sex therapy seems to have better outcomes. PMID:24066697

    Melatonin (N-acetyl-5-methoxytryptamine) is secreted during the dark hours at night by the pineal gland. After entering the circulation, melatonin acts as an endocrine factor and a chemical messenger of light and darkness. It regulates a variety of important central and peripheral actions related to circadian rhythms and reproduction. It also affects the brain, immune, gastrointestinal, cardiovascular, renal, bone and endocrine functions and acts as an oncostatic and anti-aging molecule. Many of melatonin's actions are mediated through interactions with specific membrane-bound receptors expressed not only in the central nervous system, but also in peripheral tissues. Melatonin also acts through non-receptor-mediated mechanisms, for example serving as a scavenger for reactive oxygen species and reactive nitrogen species. At both physiological and pharmacological concentrations, melatonin attenuates and counteracts oxidative stress and regulates cellular metabolism. Growing scientific evidence of reproductive physiology supports the role of melatonin in human reproduction. This review was conducted to investigate the effects of melatonin on female reproduction and to summarize our findings in this field. © 2013 The Authors.

    Until recently, the women's changing room in the Fire Station, built in 2005, has always been empty. With the arrival of Séverine Peverelly, CERN's first female firefighter, it now has a purpose. Séverine Peverelly took up her post as a firefighter in April. Séverine, who comes from Gap in France, took up her post as a firefighter in the CERN fire brigade at the beginning of April. "We were looking for a new member," explains David Peyron, Head of the Fire and Rescue Service. It didn't matter if it was a man or a woman; we needed a firefighter with the right skills, and Séverine just happened to have them." With ten years experience working in French fire services, Séverine was looking for a new challenge. "What attracted me to CERN was the international dimension, because that creates additional challenges," she explains. And these can be considerable! For one thing, every country has its own way of worki...

  7. Female pattern hair loss

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Female pattern hair loss (FPHL is a common cause of hair loss in women characterized by diffuse reduction in hair density over the crown and frontal scalp with retention of the frontal hairline. Its prevalence increases with advancing age and is associated with significant psychological morbidity. The pathophysiology of FPHL is still not completely understood and seems to be multifactorial. Although androgens have been implicated, the involvement of androgen-independent mechanisms is evident from frequent lack of clinical or biochemical markers of hyperandrogenism in affected women. The role of genetic polymorphisms involving the androgen and estrogen receptors is being increasingly recognized in its causation and predicting treatment response to anti-androgens. There are different clinical patterns and classifications of FPHL, knowledge of which facilitates patient management and research. Chronic telogen effluvium remains as the most important differential diagnosis. Thorough history, clinical examination, and evaluation are essential to confirm diagnosis. Patients with clinical signs of androgen excess require assessment of biochemical parameters and imaging studies. It is prudent to screen the patients for metabolic syndrome and cardiovascular risk factors. The treatment comprises medical and/or surgical modalities. Medical treatment should be initiated early as it effectively arrests hair loss progression rather than stimulating regrowth. Minoxidil continues to be the first line therapy whereas anti-androgens form the second line of treatment. The progressive nature of FPHL mandates long-term treatment for sustained effect. Medical therapy may be supplemented with cosmetic concealment in those desirous of greater hair density. Surgery may be worthwhile in some carefully selected patients.

    2006-05-01

    A cross-sectional study of female condom awareness, usage and concerns among the female undergraduates of the University of Ibadan was conducted in September 2004. The results of 850 out of the 879 female students interviewed were used for analysis (96.6%). Over 80% had knowledge of the female condom as a form of modern contraception and the majority of them learnt about it through the mass media (39.9%) and health workers (34.4%). However, only 11.3% had ever used the female condom, with most (40%) using it to prevent both unwanted pregnancy and sexually transmitted infections including HIV (STI/HIV). The sexual partners' approval was appreciable, accounting for about 42.7% among those that had experience of the female condom usage. Major concerns mentioned such as difficulty of inserting it into the vagina and lack of sexual satisfaction, were not different from those in earlier studies. The result of this study looks promising judging from a high awareness level of the female condom, even though its usage is low. The female condom may be an alternative strategy to combat unsafe sexual practises and its sequelae in a country like Nigeria that is male dominated.

    1996-12-01

    At the University Department of Cardiovascular Surgery in Zagreb, Croatia, we treated 81 patients with primary intracardiac myxoma, in a period from January 1975 to December 1994. There were 55 female and 26 male pts, in age from 1 month to 80 years, mean 46+/-15 years. Clinical manifestations varied from no symptoms and very poor or no clinical signs to various manifestations of chronic or acute congestive heart failure, syncope and arrhythmias with or without systemic findings such as high erythrocyte sedimentation rate, anaemia, leucocytosis, elevated gamma globulin, thrombocytopenia or low grade fever, as well as cerebrovascular accidents due to tumour embolization. Cardiac symptoms were predominant in 54 pts (66.6%) and cerebrovascular in 20 pts (24.7%). Seven pts (8.6%) were symptomless and discovered accidentally, mostly regarding on an unexplained heart murmur. In almost all the patients preoperative diagnosis of intracardiac myxoma was sufficiently established by echocardiography. The tumour was located in the left atrium in 62 pts (76.5%) and in the right atrium in 19 pts (23.5%). Delay from the onset of symptoms to the diagnosis was 6 months in average (range 10 days to 25 months). The average waiting for the operation was 9 days (range from 1 to 60 days). The echocardiographic diagnosis was confirmed during intraoperative examination followed by histological analysis. All pts underwent excision of myxoma using cardiopulmonary bypass with core and topical hypothermia and cold crystaloid cardioplegia. According to the additional preoperative and intraoperative findings, in 6 pts sinchronous mitral valve reconstruction, in 3 pts artificial mitral valve implantation and in 2 pts atrial wall reconstruction was performed. There was no perioperative mortality. After the operation, we could not evaluate all the patients long enough, mostly because of some paramedical circumstancies, such as war, migrations, etc. Twenty two pts undevent evaluation for at least 5

    Full Text Available Background: Acquired paralysis of the diaphragm is a condition caused by trauma, surgical injuries, (lung cancer surgery, esophageal surgery, cardiac surgery, thoracic surgery, and is sometimes of an unknown etiology. It can lead to dyspnea and can affect ventilatory function and patients activity. Diaphragmatic plication is a treatment method which decreases inconsistent function of diaphragm. The aim of this study is to evaluate the outcome of diaphragmatic plication in patients with acquired unilateral non-malignant diaphragmatic paralysis. Methods: From 1991 to 2011, 20 patients with acquired unilateral diaphragmatic paralysis who underwent surgery enrolled in our study in Ghaem Hospital Mashhad University of Medical Science. Patients were evaluated in terms of age, sex, BMI, clinical symptoms, dyspnea score (DS, etiology of paralysis, diagnostic methods, respiratory function tests and complication of surgery. Some tests including dyspnea score were carried out again six months after surgery. We evaluated patients with SPSS version 11.5 and Paired t-test or nonparametric equivalent. Results: Twenty patients enrolled in our study. 14 were male and 6 were female. The mean age was 58 years and the average time interval between diagnosis to surgical treatment was 38.3 months. Acquired diaphragmatic paralysis was mostly caused by trauma (in 11 patients and almost occurred on the left side (in 15 patients. Diagnostic methods included chest x-ray, CT scan, ultrasonography and sniff. Test prior to surgery the average FVC was 41.4±7 percent and the average FEV1 was 52.4±6 percent and after surgery they were 80.1±8.6 percent and 74.4±1 percent respectively. The average increase in FEV1 and FVC 63.4±4, 61.1±7.8. Performing surgery also leads to a noticeable improvement in dyspnea score in our study. Conclusion: In patients with acquired unilateral non-malignant diaphragm paralysis diaphragmatic plication is highly recommended due to the

  12. Female sexual arousal in amphibians.

    Science.gov (United States)

    Wilczynski, Walter; Lynch, Kathleen S

    2011-05-01

    Rather than being a static, species specific trait, reproductive behavior in female amphibians is variable within an individual during the breeding season when females are capable of reproductive activity. Changes in receptivity coincide with changes in circulating estrogen. Estrogen is highest at the point when females are ready to choose a male and lay eggs. At this time female receptivity (her probability of responding to a male vocal signal) is highest and her selectivity among conspecific calls (measured by her probability of responding to a degraded or otherwise usually unattractive male signal) is lowest. These changes occur even though females retain the ability to discriminate different acoustic characteristics of various conspecific calls. After releasing her eggs, female amphibians quickly become less receptive and more choosy in terms of their responses to male sexual advertisement signals. Male vocal signals stimulate both behavior and estrogen changes in amphibian females making mating more probable. The changes in female reproductive behavior are the same as those generally accepted as indicative of a change in female sexual arousal leading to copulation. They are situationally triggered, gated by interactions with males, and decline with the consummation of sexual reproduction with a chosen male. The changes can be triggered by either internal physiological state or by the presence of stimuli presented by males, and the same stimuli change both behavior and physiological (endocrine) state in such a way as to make acceptance of a male more likely. Thus amphibian females demonstrate many of the same general characteristics of changing female sexual state that in mammals indicate sexual arousal. Copyright © 2010 Elsevier Inc.

    Schaverien, J

    1996-04-01

    The literature on erotic transference and countertransference between female analyst and male patient is reviewed and discussed. It is known that female analysts are less likely than their male colleagues to act out sexually with their patients. It has been claimed that a) male patients do not experience sustained erotic transferences, and b) female analysts do not experience erotic countertransferences with female or male patients. These views are challenged and it is argued that, if there is less sexual acting out by female analysts, it is not because of an absence of eros in the therapeutic relationship. The literature review covers material drawn from psychoanalysis, feminist psychotherapy, Jungian analysis, as well as some sociological and cultural sources. It is organized under the following headings: the gender of the analyst, sexual acting out, erotic transference, maternal and paternal transference, gender and power, countertransference, incest taboo--mothers and sons and sexual themes in the transference.

  2. Perspective for Female Medical Physicists

    International Nuclear Information System (INIS)

    Naqvi, Syed Mansoor; Hasnain, Aziz Fatima

    2009-01-01

    Due to cultural and religious reasons, Pakistani women can be reluctant to seek medical attention for disorders affecting their genitals or breasts. As a result, in the case of cervical and breast cancers, oncological treatment is often not received until the diseases are in the late stages. Once a cancer is classified and the tumor marked, the role of the medical physicist begins. Medical physicists' responsibilities include treatment planning, supervising treatment through radiation, dosimetry, contouring, training, equipment selection, education, research, and supervising radiotherapy facilities. In brachytherapy, isotopes are placed at the tumor site in the form of wires or seeds. There are very few female medical physicists in Pakistan. This leads to further hesitation on the part of many women to seek treatment. To help female patients obtain needed medical care, female physics students should be encouraged to pursue the emerging field of medical physics. This would provide a new professional opportunity for female physics students and give comfort to female patients.

    1991-01-01

    Fourteen female patients with primary urethral carcinoma were treated at the Manitoba Cancer Foundation in the last twenty-nine years. The relationship of natural history to the stage, location, and therapeutic modality has been reviewed. A higher stage and length of urethral involvement affected prognosis negatively, whereas lower stage had a positive prognostic effect and location of tumor had no prognostic influence. Two patients with Stage C, who failed to received inguinal node radiotherapy, died of disease recurring in the inguinal area. Patients who received inguinal radiation (3 patients Stages B, C, and D1) had no regional recurrence. It is suggested that, for all female urethral carcinoma, bilateral ilioinguinal nodes be included in the radiation field. For radical treatment, iridium 192 insertion in combination with external beam treatment is recommended

This can be justified if we refer to data and research results that have been done in several countries. However, many women who work in the library, this does not necessarily describe that library work is a simple and easy job. However, on the contrary, work in the field of library is increasingly complex and demands the competence and mastery of information technology. Moreover, the expectations of some users who demand a fast and quality service. Therefore to answer this problem required a female librarian who has the competence, intelligent and able to become a leader for his group and can show the characteristics as a professional. As for the description of people like this people call it with the term alpha female. With the birth of alpha female figures among female librarians is expected to change the positive image of librarians and library institutions. This is because the female alpha figure in the female librarian is a figure of women who are considered "perfect" are still rare today. Keywords: library, librarian, symbolic interaction, alpha female. Abstrak Profesi pustakawan kerapkali dikaitkan dengan kaum perempuan. Hal ini dapat dibenarkan jika kita merujuk pada data dan hasil riset yang telah dilakukan di beberapa negara. Namun demikian banyaknya kaum perempuan yang bekerja di perpustakaan, ini tidak serta merta menggambarkan bahwa pekerjaaan perpustakaan merupakan pekerjaan yang sederhana dan mudah. Namun justru sebaliknya pekerjaaan di bidang perpustakaan saat ini semakin kompleks dan menuntut kompetensi dan penguasaan teknologi informasi. Apalagi harapan sebagian pengguna yang menuntut suatu pelayanan ayang cepat dan berkualitas. Oleh karena demikian untuk menjawab permasalahan ini diperlukan sosok pustakawan

    Full Text Available The objective was to learn about the experiences of women from a Health Strategy in view of the experience of sexual autonomy in the face of the female condom. It is an exploratory and qualitative study, completed in April 2010, which used semi-structured interview as data collection technique and the theory of social constructionism to aid in data analysis. Of the total of 25 women participants, after six months, only 12 were still in continuous use of the female condom. They pointed out the female condom as able to provide them with bargaining power, since it is inserted into their bodies. For some, the difficulty of trading remained for failure partner's approval. It is observed that in practice, the female condom becomes hostage of gender relations.

  8. Female urinary incontinence and sexuality

    Directory of Open Access Journals (Sweden)

    Renato Lains Mota

    Full Text Available ABSTRACT Urinary incontinence is a common problem among women and it is estimated that between 15 and 55% of them complain of lower urinary symptoms. The most prevalent form of urinary incontinence is associated with stress, followed by mixed urinary incontinence and urge urinary incontinence. It is a symptom with several effects on quality of life of women mainly in their social, familiar and sexual domains. Female reproductive and urinary systems share anatomical structures, which promotes that urinary problems interfere with sexual function in females. This article is a review of both the concepts of female urinary incontinence and its impact on global and sexual quality of life. Nowadays, it is assumed that urinary incontinence, especially urge urinary incontinence, promotes anxiety and several self-esteem damages in women. The odour and the fear of incontinence during sexual intercourse affect female sexual function and this is related with the unpredictability and the chronicity of incontinence, namely urge urinary incontinence. Female urinary incontinence management involves conservative (pelvic floor muscle training, surgical and pharmacological treatment. Both conservative and surgical treatments have been studied about its benefit in urinary incontinence and also the impact among female sexual function. Unfortunately, there are sparse articles that evaluate the benefits of female sexual function with drug management of incontinence.

    2017-07-28

    A couple may be considered to have fertility problems if they have been trying to conceive for over a year with no success. This may affect up to a quarter of all couples planning a child. It is estimated that for 40% to 50% of couples, subfertility may result from factors affecting women. Antioxidants are thought to reduce the oxidative stress brought on by these conditions. Currently, limited evidence suggests that antioxidants improve fertility, and trials have explored this area with varied results. This review assesses the evidence for the effectiveness of different antioxidants in female subfertility. To determine whether supplementary oral antioxidants compared with placebo, no treatment/standard treatment or another antioxidant improve fertility outcomes for subfertile women. We searched the following databases (from their inception to September 2016) with no language or date restriction: Cochrane Gynaecology and Fertility Group (CGFG) specialised register, the Cochrane Central Register of Studies (CENTRAL CRSO), MEDLINE, Embase, PsycINFO, CINAHL and AMED. We checked reference lists of appropriate studies and searched for ongoing trials in the clinical trials registers. We included randomised controlled trials (RCTs) that compared any type, dose or combination of oral antioxidant supplement with placebo, no treatment or treatment with another antioxidant, among women attending a reproductive clinic. We excluded trials comparing antioxidants with fertility drugs alone and trials that only included fertile women attending a fertility clinic because of male partner infertility. Two review authors independently selected eligible studies, extracted the data and assessed the risk of bias of the included studies. The primary review outcome was live birth; secondary outcomes included clinical pregnancy rates and adverse events. We pooled studies using a fixed-effect model, and calculated odds ratios (ORs) with 95% confidence intervals (CIs) for the dichotomous

    Social cognitive theory guided the design of a survey to investigate high school students' perceptions of factors affecting their career contemplations and beliefs regarding the influence of their participation in the international Science Olympiad on their subject interests and twenty-first century skills. In addition, gender differences in students' choice of competition category were studied. Mixed methods analysis of survey returns from 172 Olympiad participants from 31 countries showed that students' career aspirations were affected most by their teachers, personal interests, and parents, respectively. Students also indicated that they believed that their participation in the Olympiad reinforced their plan to choose a science, technology, engineering, and mathematics (STEM) major at college and assisted them in developing and improving their twenty-first century skills. Furthermore, female students' responses indicated that their project choices were less likely to be in the engineering category and more likely to be in the environment or energy categories. Findings are discussed in the light of increasing the awareness of the role and importance of Science Olympiads in STEM career choice and finding ways to attract more female students into engineering careers.

    Objectives To determine the prevalence of vitamin D deficiency and identify the relation between 25-hydroxyvitamin D [25(OH)D] levels and the consumption of dietary sources of vitamin D or exposure to anticonvulsants in females with Rett syndrome (RTT). Study design Retrospective review of the medical records of 284 females with RTT to determine serum 25(OH)D and parathyroid hormone levels, nutritional status, dietary sources of vitamin D, exposure to anticonvulsants, degree of mobility, and MECP2 status. Results Twenty percent of females who were tested (n=157) had 25(OH)D levels Anticonvulsants were used by 57% and 39% ambulated independently. Median 25(OH)D levels were lower in individuals who did not receive multivitamin supplements (panticonvulsants, degree of mobility, and MECP2 status did not influence 25(OH)D levels. Conclusion Vitamin D deficiency is prevalent in females with RTT. The use of multivitamin supplements or commercial formulas is associated with improved vitamin D levels. Attention to vitamin D may enhance bone mineral deposition and reduce the frequency of bone fractures in these individuals. PMID:21637127

    Full Text Available Listening skill has been recently paid great attention comparing with the other three language skills since having communication is the first and most essential need. Language learners have been using the three different listening strategies (Cognitive, Meta-cognitive, and Socio-affective to improve their listening skills in multimedia environments in particular. The main focus of this study is to determine the most preferable listening strategies employed in improving listening skills in multimedia environment by female Iranian English language learners. To achieve the goals, thirty female English language learners – twenty to twenty five - out of sixty were selected. In order to collect data IELTS test as pre-test and post-test questionnaire and interview were used. The result indicated that these language learners mainly employed meta-cognitive strategies the most in the multimedia environment. Thus, it is implied that the findings would be beneficial to the classroom practice, guide learners and lecturers as well as syllabus planners and material designers

    Cassidy-Vu, Lisa; Beck, Keli; Moore, Justin B

    2017-04-01

    Despite approximately equal numbers of male and female medical school graduates, women are entering academic medicine at a lower rate than their male colleagues. Of those who do assume a faculty position, female faculty members report higher levels of burnout, often attributable to gender-specific difficulties in clinical expectations and maintenance of work-life balance. Many of these struggles are attributable to issues that are amenable to supportive policies, but these policies are inconsistent in their availability and practice. This commentary presents evidence for inconsistencies in the day-to-day experience of female faculty members, and proposes solutions for the mitigation of the challenges experienced more often by female faculty members with the goal of diversifying and strengthening academic medicine.

    Martinelli, M; Ollé-Goig, J E

    2012-12-01

    The practice of female genital mutilation (we will use the latest definition adopted by WHO/UNFP: female genital mutilation/cutting or FGM/C) is still widespread in 28 African countries. The World Health Organisation (WHO) estimates that more than two million females undergo some form of genital mutilation every year. Its negative health impact and its ethical and human rights aspects have been discussed and attempts to eliminate it have been the objectives of several meetings promoted by national and international organisations thanks to an increased awareness related to FGM/C in those countries practicing it and also, maybe due to the number of Africans migrating to industrialized countries. We review the present situation in Djibouti, a small country in the Horn of Africa, where 98 % of the female population has suffered different forms of FGM/C.

    2010-04-01

    The purpose of this study was to examine gender disparities in dental leadership and academics in the United States. Nine journals that represent the dental specialties and high published impact factors were selected to analyze the percentage of female dentists' first and senior authorship for the years 1986, 1990, 1995, 2000, 2005, and 2008. Data on appointment status and female deanship were collected from the American Dental Association (ADA) survey, and the trends were studied. The proportion of female presidents in ADA-recognized specialty organizations was also calculated. Overall, the increase in first female authorship was not statistically significant, but the increase of last female authorship was statistically significant in a linear trend over the years. The percentage of tenured female faculty members and female deans in U.S. dental schools increased by factors of 1.7 and 9, respectively, during the study period. However, female involvement in professional organizations was limited. Findings from this study indicate that female participation in authorship and leadership has increased over time. Nevertheless, females are still a minority in dental academics and leadership.

    Full Text Available Abstract: This paper investigates the process of internationalisation of Brazilian literature in the twenty-first century from the perspective of the publishing market. For this, we analyse how Brazil has responded to globalisation and what effects of cultural globalisation can be seen in the Brazilian literary scene, focusing on the novel. Observing the movement of the novelists throughout the globe, the reception of Brazilian literature in the United Kingdom and the relations between art and the literary market in Brazil, we intend to provoke some reflections on Brazilian cultural history in the light of the twenty-first century.

  20. [Female erotic dreams and female seed in ancient Greek medicine].

    2009-01-01

    This paper analyses passages of the Hippocratic Corpus, of Aristotle and Galen about oneirogmòs, spermatic emission during sleep, referring specifically to women. Into the Hippocratic texts there is only one gynaecological case among many cases about males: for them this nocturnal emission is symptom of dangerous illness and De genitura gives a causal explanation of such phaenomenon. Instead, in Aristotle and Galen erotic dream is evidence for or against emission of female seed and female contribution to generation. As the argument ofHistoria animalium book X shows clear theoretical differences from that of De generatione animalium, the topic of erotic dream also concerns issues of authenticity.

    Full Text Available The study examines the core meaning of intrinsic shopping to understand their experimental aspects of recreational and leisure shopping. The study focus only on female shoppers of age group ranging from 25-30, and understand their mall experiences because this segment is newly transform into self dependent segment which have less social and familial liabilities and have enough enthusiasm to explore the world or their boundaries. The Grounded theory use for identification of recreational shopping themes which are (a seeking experiences and (b experimental shopping and each have respective sub themes. The themes are connected to the key idea that shoppers are motivated by their expectations and desires. The study uses social constructivism to find and understand the shopper meanings in real terms rather than imposing and judgment on them. The findings described the way people do recreational shopping and how shopping malls use as leisure space and become facilitators of recreational shopping activities. Females use malls to fulfill their recreational and leisure shopping experiences as this is the great way of enjoying shopping for females of small towns. In malls females not only enjoy product experiences but services experiences also which makes their shopping interesting. The way the female of this age category use malls help the marketers and retailers to understand this segment shopping patterns.

  2. Female Fitness in the Blogosphere

    2013-07-01

    Full Text Available This article analyzes self-portrayals and gender constructions among female personal trainers within an Internet-mediated framework of fitness culture. The empirical material comes from a close examination of three strategically selected blogs. The result shows that some of the blogs clearly build upon what Connell calls emphasized femininity, as a means of legitimizing and constructing appropriate female fitness. In addition, there are also tendencies of sexualization in text and imagery present. As such, these self-representations are framed within a cultural history of body fitness dominated by stereotypical ways of perceiving masculinity and femininity. However, this does not capture the entire presentation of the self among the analyzed fitness bloggers. The blogs also point in the direction of ongoing negotiations and subversions of traditional gender norms. Among other things, they show how irony and humor are used as a means of questioning normative gender constructions while empowering female fitness and bodyliness.

  3. Mitochondrial functionality in female reproduction

    Full Text Available In most animal species female germ cells are the source of mitochondrial genome for the whole body of individuals. As a source of mitochondrial DNA for future generations the mitochondria in the female germ line undergo dynamic quantitative and qualitative changes. In addition to maintaining the intact template of mitochondrial genome from one generation to another, mitochondrial role in oocytes is much more complex and pleiotropic. The quality of mitochondria determines the ability of meiotic divisions, fertilization ability, and activation after fertilization or sustaining development of a new embryo. The presence of normal number of functional mitochondria is also crucial for proper implantation and pregnancy maintaining. This article addresses issues of mitochondrial role and function in mammalian oocyte and presents new approaches in studies of mitochondrial function in female germ cells.

  4. Immune Aspects of Female Infertility

    2016-05-01

    Full Text Available Immune infertility, in terms of reproductive failure, has become a serious health issue involving approximately 1 out of 5 couples at reproductive age. Semen that is defined as a complex fluid containing sperm, cellular vesicles and other cells and components, could sensitize the female genital tract. The immune rejection of male semen in the female reproductive tract is explained as the failure of natural tolerance leading to local and/or systemic immune response. Present active immune mechanism may induce high levels of anti-seminal/sperm antibodies. It has already been proven that iso-immunization is associated with infertility. Comprehensive studies with regards to the identification of antibody-targets and the determination of specific antibody class contribute to the development of effective immuno-therapy and, on the other hand, potential immuno-contraception, and then of course to complex patient diagnosis. This review summarizes the aspects of female immune infertility.

  5. Female circumcision: persistence amid conflict.

    Science.gov (United States)

    Douglas, J H

    1998-01-01

    The continuing practice of female circumcision (removal of varying degrees of external genitalia) was perhaps the most emotional issue discussed at the Ninth International Congress on Women's Health Issues, held in June in Alexandria, Egypt. The results of two studies presented at the Congress have resulted to an argument. Others view female circumcision as a traditional folk practice, similar to scarring of the skin or elongation of the lips among certain African tribes and should not be subjected to "cultural imperialism" from abroad. Instead, the procedure could best be eradicated through focused education--telling patients that it is not required by Islam and that it can be detrimental to health. However, this suggestion was hotly debated by members of the audience who insisted that female circumcision should be considered as a form of child abuse and thus properly addressed as a political issue.

    Kumari, R

    1995-01-01

    This article describes the life conditions of female adolescents in India and issues such as health, discrimination in nutrition and literacy, child labor, early marriage, juvenile delinquency, and violence against girls in rural areas of India. Data are obtained from interview samples conducted among 12 villages in north India. Female adolescents suffer from a variety of poverty-ridden village life conditions: caste oppression, lack of facilities, malnutrition, educational backwardness, early marriage, domestic burden, and gender neglect. Girls carry a heavy work burden. Adolescence in rural areas is marked by the onset of puberty and the thrust into adulthood. Girls have no independent authority to control their sexuality or reproduction. Girls are expected to get married and produce children. Control of female sexuality is shifted from the father to the husband. There is a strong push to marry girls soon after menstruation, due to the burden of imposing strict restrictions on female sexuality, the desire to reduce the burden of financial support, and the need to ensure social security for daughters. Girls may not go out alone or stay outside after dark. Many rural parents fear that education and freedom would ruin their daughter. Girls develop a low self-image. Rural villages have poor sanitation, toilet facilities, and drainage systems. Girls are ignorant of health and sex education and lack access to education. The neglect of female children includes malnutrition, sex bias, and early marriage. In 1981, almost 4 out of every 100 girls had to work. 5.527 million girls 5-14 years old were child laborers. Girls are veiled, footbound, circumcised, and burnt by dowry hungry in-laws. Female delinquents are subjected to sexual harassment and sometime to sexual abuse while in custody. Cows are treated better in rural India than women. Gender disparity is caused by the perpetuation of patriarchal masculine values.

    Full Text Available Das Buch präsentiert mit der Berufsbiographie von Josefine Erkens die Schwierigkeiten in den ersten Jahrzehnten des letzten Jahrhunderts, einen für Frauen neuen Berufszweig zu etablieren. Neben Modernisierungsbestrebungen in der Polizei als solcher bestimmen sozialpolitische Reformbemühungen eines Teils der Frauenbewegung sowie Professionalisierung von Frauenarbeit die Durchsetzung dieses neuen Berufsfeldes. Doch unterschiedliche Konzepte zum Berufsbild der weiblichen Polizistin, die vorherrschende Nichtakzeptanz von Frauen in Führungspositionen sowie eine ablehnende, mißtrauische Haltung zu berufstätigen Frauen markieren die Hindernisse des vorgestellten beruflichen Lebenslaufs.Taking the professional biography of Josephine Erkens as an example, this book traces the difficulties women had to face when trying to establish a new branch of an occupation during the first few decades of the last century. Apart from efforts at modernization within the police force itself, social political strivings for reform of a part of the women’s movement as well as processes of professionalization were instrumental in the establishment of this new branch. However, different concepts of the job outline of policewomen, the prevailing non-recognition of women in positions of leadership as well as a negative and suspicious attitude towards working women greatly impeded this professional biography.

    Full Text Available This article is devoted to the process of reforming the global financial system and world economic organizations since the foundation of the International Monetary Fund at the Bretton Woods Conference in 1944 to present time. Special attention is given to results of cooperation of the IMF and the "Group of Twenty"in the context of the world financial crisis 2008-2009. This article mentions the key benchmarks of the historical development of world economy: foundation of the Bretton Woods financial system, rejection of the gold standard at the Jamaica Conference, transition to the floating exchange rates, the wave of crises in the 1990-s, the world financial crisis of 2008-2009. The process of evolution of the IMF within the framework of these global events is considered here. The cooperation of EU, IMF and "Group of Twenty" is considered. The reforms of the IMF and their results are analyzed. The policy of the IMF at different historical stages of its evolution is estimated. As well as it results, the article also deals with the formation and development of the "Group of Twenty". The increasing role of the "Group of Twenty" in the global economic governance and reforming the IMF is considered. Especially is marked the necessity of the further reforms of the IMF and increasing of participation of the "G-20" in the world economic and politic system.

  10. Improving the temporal transposability of lumped hydrological models on twenty diversified U.S. watersheds

    2015-03-01

    Full Text Available Study region: Twenty diversified U.S. watersheds. Study focus: Identifying optimal parameter sets for hydrological modeling on a specific catchment remains an important challenge for numerous applied and research projects. This is particularly the case when working under contrasted climate conditions that question the temporal transposability of the parameters. Methodologies exist, mainly based on Differential Split Sample Tests, to examine this concern. This work assesses the improved temporal transposability of a multimodel implementation, based on twenty dissimilar lumped conceptual structures and on twenty U.S. watersheds, over the performance of the individual models. New hydrological insights for the region: Individual and collective temporal transposabilities are analyzed and compared on the twenty studied watersheds. Results show that individual models performances on contrasted climate conditions are very dissimilar depending on test period and watershed, without the possibility to identify a best solution in all circumstances. They also confirm that performance and robustness are clearly enhanced using an ensemble of rainfall-runoff models instead of individual ones. The use of (calibrated weight averaged multimodels further improves temporal transposability over simple averaged ensemble, in most instances, confirming added-value of this approach but also the need to evaluate how individual models compensate each other errors. Keywords: Rainfall-runoff modeling, Multimodel approach, Differential Split Sample Test, Deterministic combination, Outputs averaging

  6. Twenty-first century learning for teachers: helping educators bring new skills into the classroom.

    Science.gov (United States)

    Wilson, John I

    2006-01-01

    The motivation behind every educator's dedication and hard work in the classroom is the knowledge that his or her teaching will result in students' success in life. Educators are committed to implementing twenty-first century skills; they have no question that students need such skills to be equipped for life beyond school. Members of the National Education Association are enthusiastic about the Partnership for 21st Century Skills framework, yet express frustration that many schools do not have adequate resources to make the necessary changes. Teaching these skills poses significant new responsibilities for schools and educators. To make it possible for teachers to build twenty-first century skills into the curriculum, physical and policy infrastructures must exist, professional development and curriculum materials must be offered, and meaningful assessments must be available. With an established understanding of what skills need to be infused into the classroom-problem solving, analysis, and com- munications-and educators' commitment to the new skill set, this chapter explores how to make such a dramatic reform happen. The author discusses existing strategies that will guide educators in infusing twenty-first century skills into traditional content areas such as math, English, geography, and science. Ultimately, public policy regarding educational standards, professional development, assessments, and physical school structures must exist to enable educators to employ twenty-first century skills, leading to student success in contemporary life. Any concern about the cost of bringing this nation's educational system up to par internationally should be offset by the price that not making twenty-first century skills a priority in the classroom will have on future economic well-being.

    There is strong evidence of sex differences in mental rotation tasks. Transsexualism is an extreme gender identity disorder in which individuals seek cross-gender treatment to change their sex. The aim of our study was to investigate if male-to-female (MF) and female-to-male (FM) transsexuals receiving cross-sex hormonal treatment have different patterns of cortical activation during a three-dimensional (3D) mental rotation task. An fMRI study was performed using a 3-T scan in a sample of 18 MF and 19 FM under chronic cross-sex hormonal treatment. Twenty-three males and 19 females served as controls. The general pattern of cerebral activation seen while visualizing the rotated and non-rotated figures was similar for all four groups showing strong occipito-parieto-frontal brain activation. However, compared to control males, the activation of MF transsexuals during the task was lower in the superior parietal lobe. Compared to control females, MF transsexuals showed higher activation in orbital and right dorsolateral prefrontal regions and lower activation in the left prefrontal gyrus. FM transsexuals did not differ from either the MF transsexual or control groups. Regression analyses between cerebral activation and the number of months of hormonal treatment showed a significant negative correlation in parietal, occipital and temporal regions in the MF transsexuals. No significant correlations with time were seen in the FM transsexuals. In conclusion, although we did not find a specific pattern of cerebral activation in the FM transsexuals, we have identified a specific pattern of cerebral activation during a mental 3D rotation task in MF transsexuals under cross-sex hormonal treatment that differed from control males in the parietal region and from control females in the orbital prefrontal region. The hypoactivation in MF transsexuals in the parietal region could be due to the hormonal treatment or could reflect a priori cerebral differences between MF transsexual

    To identify the impact of family life on the ways women practice rural medicine and the changes needed to attract women to rural practice. Census of women rural doctors in Victoria in 2000, using a self-completed postal survey. General and specialist practice. Two hundred and seventy-one female general practitioners and 31 female specialists practising in Rural, Remote and Metropolitan Area Classifications 3-7. General practitioners are those doctors with a primary medical degree and without additional specialist qualifications. Interaction of hours and type of work with family responsibilities. Generalist and specialist women rural doctors carry the main responsibility for family care. This is reflected in the number of hours they work in clinical and non-clinical professional practice, availability for on-call and hospital work, and preference for the responsibilities of practice partnership or the flexibility of salaried positions. Most of the doctors had established a satisfactory balance between work and family responsibilities, although a substantial number were overworked in order to provide an income for their families or meet the needs of their communities. Thirty-six percent of female rural general practitioners and 56% of female rural specialists preferred to work fewer hours. Female general practitioners with responsibility for children were more than twice as likely as female general practitioners without children to be in a salaried position and less likely to be a practice partner. The changes needed to attract and retain women in rural practice include a place for everyone in the doctor's family, flexible practice structures, mentoring by women doctors and financial and personal recognition. Women make up less than a quarter of the rural general practice workforce and an even smaller percentage of the specialist rural medical workforce. As a result their experiences are not well articulated in research on rural medical practice and their needs are

    Full Text Available The aim of this research was to perceive, on a great sample of sportswomen, di- vided according to the age, the current trend of the development of this ability related to some former researches that means to perceive concurrence or possibly distinguishing of those values related to the previous ones. On the sample of 792 sportswomen, at the age of 8 till 21, divided on sub-samples according to the age it was measured dynamometer force by classic methods of dynamometer measuring. Such obtained results placed in a data base of a Provincial Institution for sport in Novi Sad, were processed by methods of descriptive statistics, on the basis of which it was carried out a developing curve of this ability of a contemporary sports youth. Based on the size of some sub-samples it could be concluded that the number of some respondents within them at the age of 10 to 21 in most cases allow relevant concluding about developing trends of explosive force, altho- ugh it must be noticed that less presence of respondents in initial and final years allows only conditional conclusion. In sportswomen a developing curve is being characterized by a steady time of obtaining of maximum values (at the age of twenty till twenty-one and only at the muscles of legs maximum values are noted earlier at the age of eighteen till twenty. Dynamics of the development of dynamometer force till those maximum va- lues has a different trend for different muscular groups. After achieving of maximum values, force is being maintained constantly for a long time on a lower level, and only varies in rare cases. Within a female population a developing trend of dynamometer force is very prone to bigger varying of some muscular groups but because of that top values are being noted almost in the same period of a development of an individual. The time of lasting of those maximum values related to the male population is considerably shorter. Though, after the peak, sportswomen maintain the level

    2015-10-01

    In certain populations, female Japanese macaques (Macaca fuscata) mount both males and females. Vasey (2007) proposed that female-female sexual mounting in Japanese macaques may be a neutral evolutionary by-product of a purported adaptation, namely, female-male mounting. In this study, we aim to further examine the proposed link between female-male and female-female mounting in Japanese macaques by comparing the structural characteristics that define both forms of mounting. We do so using Eshkol-Wachman Movement Notation (EWMN), a globographic reference system that can be used to describe the position of body segments. No significant differences were observed in the female mounters' positioning of eight different body segments (i.e., lower torso, mid-torso, upper torso, upper arm, lower arm, upper leg, lower leg, and foot) during female-male and female-female mounting. This finding lends support to the conclusion that female-female and female-male mounting are structurally, and thus, evolutionarily, related. Copyright © 2015 Elsevier B.V. All rights reserved.

    Full Text Available Background: The aim of this study was to study the practice pattern, personal profile, and work-family balance of male and female ophthalmologists in India. Materials and Methods: This study was conducted through 41 point questionnaire sent to the members of All India Ophthalmological Society dealing with practice profile and personal circumstances of ophthalmologists. Results: Six hundred and twenty-two (8% responses were obtained out of 7723 invitations sent. A total of 452 were male and 170 were female ophthalmologists. Age group of 30-39 years was most common age of respondents (male 155; 35.3%; female 81; 47.6%. Larger number of male ophthalmologists (157; 34.7% worked for more than 9 h a day than female ophthalmologists (41; 24.1% (P = 0.01. Larger number of male ophthalmologists (229; 50.7% earned more than Rs. 1 lakh/month than female ophthalmologists (55; 32.4% (P = 0.00001 More female ophthalmologists (21; 12.4% than males (26; 5.8% said that they faced cultural, ethnic or gender bias at work place (P = 0.002. Forty-four (25.9% female and 54 (12% male ophthalmologists said that they often curtailed their work for family needs (P = 0.0001. Two hundred and fifty-two (55.8% male ophthalmologists and 78 (45.9% female ophthalmologists considered their profession rewarding (P = 0.02. Conclusion: Ophthalmology as a profession was considered rewarding by both male and female ophthalmologists. However, female ophthalmologists were curtailing their work for family needs and earning less than male ophthalmologists. Female ophthalmologists were also subject to gender bias at workplace. These issues need to be tackled to improve the work satisfaction of ophthalmology workforce.

    Lavie-Ajayi, Maya; Joffe, Hélène

    2009-01-01

    This study examines women's social representations of female orgasm. Fifty semi-structured interviews were conducted with British women. The data were thematically analysed and compared with the content of female orgasm-related writing in two women's magazines over a 30-year period. The results indicate that orgasm is deemed the goal of sex with emphasis on its physiological dimension. However, the women and the magazines graft onto this scientifically driven representation the importance of relational and emotive aspects of orgasm. For the women, particularly those who experience themselves as having problems with orgasm, the scientifically driven representations induce feelings of failure, but are also resisted. The findings highlight the role played by the social context in women's subjective experience of their sexual health.

    Full Text Available From his first film—a twenty-minute short, “Expectations” (1982—to his last—a three-hour masterpiece, 'Yi Yi' (2000—Edward Yang, one of the leading figures of the Taiwan New Cinema movement, devoted his career to portraying the impact of neoliberal capitalism on the lives of the citizens of Taipei. Interestingly, Yang’s films often employ female perspectives to criticize Taiwan’s education system and transnational corporations for perpetuating neoliberal capitalism’s ideology of self-fulfillment and upward mobility. This paper draws upon feminist film theory to investigate the ways in which Yang’s third feature, 'The Terrorizers' (1986, utilizes various innovative cinematic languages to engender a multitude of women’s perspectives to expose male voyeurism and ultimately criticize the impact of neoliberal capitalism in Taipei.

    Full Text Available study was conducted in twenty villages of Lahore district to assess the suitability of ground water for irrigation. Three water samples were collected from each of twenty villages and were analyzed for electrical conductivity (EC, sodium adsorption ratio (SAR, residual sodium carbonate (RSC and chloride concentration. Out of total 60 water samples, 7 (11.7% were fit, 7 (11.7% were marginally fit, and remaining 46 (76.6% were unfit for irrigation. Twenty eight samples (46.6% had electrical conductivity higher than permissible limit (i.e. >1250 µS cm-1, 19 samples (31.6% were found with high SAR (i.e. >10 (m mol L-10. 5, 44 samples (73.3% had high RSC (i.e. >2.5 me L-1 and 10 samples (16.6% were found unfit for irrigation due to high concentration of chloride (i.e. >3.9 me L-1. It can be inferred from data that quality of available ground water in most ofthe villages is not suitable for sustainable crop production and soil health.

  7. [Clinical comments on female homosexuality].

    Zeul, M

    1993-02-01

    In psychoanalytic theory, homosexual women are regarded as being possessed by violent hatred of the mother. They are held to identify with the male or the phallic and to display an absence of "normal" femaleness. Their attendant immaturity makes them incapable of love. The author takes issue with the assumption that normality is synonymous with mature, reciprocal heterosexuality. With reference to a case study of a homosexual woman, she traces the structure of a lesbian love relationship. The patient is the involuntary witness of sexual intercourse between the parents. The mixture of alarm and excitement which this arouses sparks off female desires that revive early libidinous experiences with the mother. The girl desires her mother, without however identifying with the father. In her later relationships with women she does not relate to her partners as a disguised man but as a woman. Identification with the father serves as a defence against the desire for-and the fear of-identification at a female level.

    Full Text Available Lauren L Levy, Jason J Emer Department of Dermatology, Mount Sinai School of Medicine, New York, NY, USA Abstract: Hair loss is a commonly encountered problem in clinical practice, with men presenting with a distinctive pattern involving hairline recession and vertex balding (Norwood-Hamilton classification and women exhibiting diffuse hair thinning over the crown (increased part width and sparing of the frontal hairline (Ludwig classification. Female pattern hair loss has a strikingly overwhelming psychological effect; thus, successful treatments are necessary. Difficulty lies in successful treatment interventions, as only two medications – minoxidil and finasteride – are approved for the treatment of androgenetic alopecia, and these medications offer mediocre results, lack of a permanent cure, and potential complications. Hair transplantation is the only current successful permanent option, and it requires surgical procedures. Several other medical options, such as antiandrogens (eg, spironolactone, oral contraceptives, cyproterone, flutamide, dutasteride, prostaglandin analogs (eg, bimatoprost, latanoprost, and ketoconazole are reported to be beneficial. Laser and light therapies have also become popular despite the lack of a profound benefit. Management of expectations is crucial, and the aim of therapy, given the current therapeutic options, is to slow or stop disease progression with contentment despite patient expectations of permanent hair regrowth. This article reviews current perspectives on therapeutic options for female pattern hair loss.

    Activity of Swift Foxes (Vulpes velox) at den sites was studied in northwestern Texas during pup rearing seasons in 2000 and 2001 to determine role of males in parental care. Twenty-four percent of radio-collared females with a potential to breed successfully raised pups to eight weeks of age. We intensively monitored presence and absence of male and female Swift Foxes at two den sites each year. Females were present >2.6 times more at den sites than males during the pup rearing season. Female and male Swift Foxes largely stayed at dens during diurnal hours and were active away from dens during nocturnal and crepuscular hours. Females and males spent 12.4% and 3.0% more time at dens before pups emerged, than after pups emerged, respectively. Following depredation of one male parent, the female spent 29% less time at the den site. Decrease in time spent at the den by the female following loss of her mate suggested that loss of one parent might severely impact recruitment of Swift Foxes. Our observations indicated that intense Coyote (Canis latrans) depredation may severely impact pup-rearing success as well as the parental care within Swift Fox family groups.

Many medical students decide against surgery as a profession due to the long work hours and family strain. The pregnant female surgical resident has an added stress factor compared to her male counterpart. Methods: We distributed an electronic, online 26-question survey to 32 general surgery programs in the southwestern region of the United States. Each program distributed our survey to the female surgical residents who had been pregnant during residency in the last 5 years. Each program was re-contacted 6 weeks after the initial contact. Most questions were in a 5-point Likert scale format. The responses were collected and analyzed using the Survey Monkey website. Results: An unvalidated survey was sent to 32 general surgery programs and 26 programs responded (81%. Each program was asked for the total number of possible responses from female residents that met our criteria (60 female residents. Seven of the programs (27% stated that they have had zero residents pregnant. We had 22 residents respond (37%. Over half of the residents (55% were pregnant during their 2nd or 3rd year of residency, with only 18% pregnant during a research year. Thirty-one percent had a lower American Board of Surgery In-Training Exam (ABSITE score. Ninety percent of the residents were able to take 4 weeks or more for maternity leave. Most of the residents (95% stated that they would do this again during residency given the opportunity, but many of the residents felt that returning back to work

    Full Text Available The popularity of female soccer is increasing as well as the number of females playing soccer. Similarly, over the last twenty or so years, research in soccer has increased significantly, but a large disparity exists in the volume of studies involving male and female players. As a consequence of this, female players remain less well understood compared to males. The purpose of the present narrative review was to describe morphological characteristics, physiological demands, physical abilities and injuries in female soccer players. Physiological demands are similar between men’s and women’s soccer, but competitive women’s matches were characterized by nearly 33% less distance covered, although at higher intensity levels (maximum speeds greater than 15 km/h than typically found in the men’s game. Sub-elite female players also tended to run less at higher intensity levels at the end of both halves in comparison with elite female players. High intensity running is an important factor of success in soccer since many critical moments of the game occur under this condition. The ability to rapidly change direction also determined elite, sub-elite and amateur levels. The implementation of functional training, which focused on soccer-specific drills and plyometric exercises, to improve explosive power, may improve conditioning in female soccer players as well as decrease the risk of injuries which was 3-8 times higher in females compared to males. This review presents an in-depth overview of the most influential factors for determining success in female soccer.

    Female genital mutilation (FGM) is illegal in the UK but nevertheless practised in some immigrant communities. Effective educational approaches are required to inform policy and to direct resources, often in the voluntary sector. The opinions in this article arise from discussions with professionals and members of FGM-practising communities. We highlight the importance of sharing experiences and expertise across health and social care professionals as well as working in partnership with culturally sensitive Non-Governmental Organisations. Enlisting the support of men and religious leaders is crucial to breaking down barriers in male-dominated communities and dispelling myths about FGM being a 'requirement' of faith.

    A graded shuttle run test was used to assess differences in physiological parameters between playing positions in elite female basketball players. Twenty-four female basketball players (8 guards, 8 forwards, and 8 centers) who played for the senior national teams of Slovenia and Serbia were tested with the 30-15 intermittent fitness test. During the shuttle run, the following physiological parameters were measured: oxygen consumption ((Equation is included in full-text article.)), carbon dioxide production ((Equation is included in full-text article.)), pulmonary ventilation (VE) breath by breath, respiratory quotient, oxygen pulse as the (Equation is included in full-text article.)vs. HR ratio and [LA]. No significant differences were found for any of the measures between the 3 playing positions. Although this finding was surprising, future studies should try to determine whether the tactics used in female basketball determine that the interpositional differences seen in male basketball are not evident.

  17. The design and performance of a twenty barrel hydrogen pellet injector for Alcator C-Mod

    1994-05-01

    A twenty barrel hydrogen pellet injector has been designed, built and tested both in the laboratory and on the Alcator C-Mod Tokamak at MIT. The injector functions by firing pellets of frozen hydrogen or deuterium deep into the plasma discharge for the purpose of fueling the plasma, modifying the density profile and increasing the global energy confinement time. The design goals of the injector are: (1) Operational flexibility, (2) High reliability, (3) Remote operation with minimal maintenance. These requirements have lead to a single stage, pipe gun design with twenty barrels. Pellets are formed by in- situ condensation of the fuel gas, thus avoiding moving parts at cryogenic temperatures. The injector is the first to dispense with the need for cryogenic fluids and instead uses a closed cycle refrigerator to cool the thermal system components. The twenty barrels of the injector produce pellets of four different size groups and allow for a high degree of flexibility in fueling experiments. Operation of the injector is under PLC control allowing for remote operation, interlocked safety features and automated pellet manufacturing. The injector has been extrusively tested and shown to produce pellets reliably with velocities up to 1400 m/sec. During the period from September to November of 1993, the injector was successfully used to fire pellets into over fifty plasma discharges. Experimental results include data on the pellet penetration into the plasma using an advanced pellet tracking diagnostic with improved time and spatial response. Data from the tracker indicates pellet penetrations were between 30 and 86 percent of the plasma minor radius

    Public education is the key to individual and business prosperity. With a vested stake in education, educators, employers, parents, policymakers, and the public should question how this nation's public education system is faring. Knowing that recent international assessments have shown little or no gains in American students' achievement, the author asserts the clear need for change. As both a large American corporate employer and a provider of technology for schools, Dell is concerned with ensuring that youth will thrive in their adult lives. Changing workplace expectations lead to a new list of skills students will need to acquire before completing their schooling. Through technology, Dell supports schools in meeting educational goals, striving to supply students with the necessary skills, referred to as twenty-first century skills. The Partnership for 21st Century Skills, of which Dell is a member, has led an initiative to define what twenty-first century learning should entail. Through extensive research, the partnership has built a framework outlining twenty-first century skills: analytical thinking, communication, collaboration, global awareness, and technological and economic literacy. Dell and the partnership are working state by state to promote the integration of these skills into curricula, professional development for teachers, and classroom environments. The authors describe two current initiatives, one in Virginia, the other in Texas, which both use technology to help student learning. All stakeholders can take part in preparing young people to compete in the global economy. Educators and administrators, legislators, parents, and employers must play their role in helping students be ready for what the workforce and the world has in store for them.

    Obstructive sleep apnea (OSA) is a common disorder, and continuous airway positive pressure (CPAP) is considered to be the gold standard of therapy. CPAP however is known to have problems with adherence, with many patients eventually abandoning the device. The purpose of this paper is to assess secular trends in CPAP adherence over the long term to see if there have been meaningful improvements in adherence in light of the multiple interventions proposed to do so. A comprehensive systematic literature review was conducted using the Medline-Ovid, Embase, and Pubmed databases, searching for data regarding CPAP adherence over a twenty year timeframe (1994-2015). Data was assessed for quality and then extracted. The main outcome measure was reported CPAP non-adherence. Secondary outcomes included changes in CPAP non-adherence when comparing short versus long-term, and changes in terms of behavioral counseling. Eighty-two papers met study inclusion/exclusion criteria. The overall CPAP non-adherence rate based on a 7-h/night sleep time that was reported in studies conducted over the twenty year time frame was 34.1 %. There was no significant improvement over the time frame. Behavioral intervention improved adherence rates by ~1 h per night on average. The rate of CPAP adherence remains persistently low over twenty years worth of reported data. No clinically significant improvement in CPAP adherence was seen even in recent years despite efforts toward behavioral intervention and patient coaching. This low rate of adherence is problematic, and calls into question the concept of CPAP as gold-standard of therapy for OSA.

    Why should the multicultural society of Canada outlaw female genital mutilation (FGM) as proposed by federal Justice Minister Allan Rock or allow avoidance of the procedure to be a legitimate reason for gaining refugee status? Is this anti-FGM position simply an ethnocentric stance that would be called racism in other circumstances? Canadian objections to FGM can not arise from objections about mutilation of a child's sexual organs because male circumcision is legal in Canada, although it, too, is medically questionable. Perhaps Rock is being patriarchal in reserving his concern for females. In Somali culture, women determine the nature and extent of FGM, so Rock may simply be exhibiting his inability to understand other cultures. On the other hand, it is politically incorrect for Canadian government workers to criticize other cultures, and immigrants are assured that their values and beliefs will be accommodated in Canada. Thus, polygamy among Somali immigrants is ignored. The question is why should FGM be a major exception and invoke efforts at repression instead of a respect for diversity.

  1. Hormesis and Female Sex Hormones

    Full Text Available Hormone replacement after menopause has in recent years been the subject of intense scientific debate and public interest and has sparked intense research efforts into the biological effects of estrogens and progestagens. However, there are reasons to believe that the doses used and plasma concentrations produced in a large number of studies casts doubt on important aspects of their validity. The concept of hormesis states that a substance can have diametrically different effects depending on the concentration. Even though estrogens and progestagens have proven prone to this kind of dose-response relation in a multitude of studies, the phenomenon remains clearly underappreciated as exemplified by the fact that it is common practice to only use one hormone dose in animal experiments. If care is not taken to adjust the concentrations of estrogens and progestagens to relevant biological conditions, the significance of the results may be questionable. Our aim is to review examples of female sexual steroids demonstrating bidirectional dose-response relations and to discuss this in the perspective of hormesis. Some examples are highlighted in detail, including the effects on cerebral ischemia, inflammation, cardiovascular diseases and anxiety. Hopefully, better understanding of the hormesis phenomenon may result in improved future designs of studies of female sexual steroids.

    Hair loss is a commonly encountered problem in clinical practice, with men presenting with a distinctive pattern involving hairline recession and vertex balding (Norwood-Hamilton classification) and women exhibiting diffuse hair thinning over the crown (increased part width) and sparing of the frontal hairline (Ludwig classification). Female pattern hair loss has a strikingly overwhelming psychological effect; thus, successful treatments are necessary. Difficulty lies in successful treatment interventions, as only two medications – minoxidil and finasteride – are approved for the treatment of androgenetic alopecia, and these medications offer mediocre results, lack of a permanent cure, and potential complications. Hair transplantation is the only current successful permanent option, and it requires surgical procedures. Several other medical options, such as antiandrogens (eg, spironolactone, oral contraceptives, cyproterone, flutamide, dutasteride), prostaglandin analogs (eg, bimatoprost, latanoprost), and ketoconazole are reported to be beneficial. Laser and light therapies have also become popular despite the lack of a profound benefit. Management of expectations is crucial, and the aim of therapy, given the current therapeutic options, is to slow or stop disease progression with contentment despite patient expectations of permanent hair regrowth. This article reviews current perspectives on therapeutic options for female pattern hair loss. PMID:24039457

    In July 1976, an industrial accident contaminated a residential area surrounding Seveso, Italy, with high levels of 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD). The exposure was acute, relatively pure, and affected more than 45,000 men, women, and children. By February 1978, 193 chloracne cases, mostly children, had been identified in the exposed population. Twenty years after, we conducted a case-control study on subjects diagnosed with chloracne and control subjects, who had not developed chloracne after the accident, to evaluate their TCDD plasma levels, as well as the exposure-response relationship and possible determinants of susceptibility to TCDD effects in this population.

In early days, RNS was mainly used to reach the maximum performance in speed. Today, RNS is also used to obtain powerefficient (tradeoffs speed......-power) and reliable systems (redundant RNS). Advances in microelectronics and CAD tools play an important role in favoring one technology over another, and a winning choice of the past may become at disadvantage today. In this paper, we address a number of factors influencing the choice of RNS as the winning solution...

    The accident at the Chernobyl NPP (nuclear power plant) was the most serious ever to have occurred in the history of nuclear energy. The consumption of contaminated foodstuffs in affected areas was a significant source of irradiation for the population. A wide range of different countermeasures have been used to reduce exposure of people and to mitigate the consequences of the Chernobyl accident for agriculture in affected regions in Belarus, Russia and Ukraine. This paper for the first time summarises key data on countermeasure application over twenty years for all three countries and describes key lessons learnt from this experience. (review)

    Full Text Available This empirical view on the current „state” of Romania has as main objective to emphasize that the contemporary economic crisis actually revealed some other escalated crises in the very heart of the Romanian society. The vicious circle determined by three crises – one political, another social-institutional and last, but not least, a cultural one, continuously weakened the state for the last twenty years. Romania will overcome the economic crisis but the key for walking out of the above-mentioned circle would be the real transformation of its core systems – political, institutional and educational.

    The accident at the Chernobyl NPP (nuclear power plant) was the most serious ever to have occurred in the history of nuclear energy. The consumption of contaminated foodstuffs in affected areas was a significant source of irradiation for the population. A wide range of different countermeasures have been used to reduce exposure of people and to mitigate the consequences of the Chernobyl accident for agriculture in affected regions in Belarus, Russia and Ukraine. This paper for the first time summarises key data on countermeasure application over twenty years for all three countries and describes key lessons learnt from this experience. (review)

    Increasing knowledge on genetic etiology of pediatric neurologic disorders is affecting the practice of the specialty. I reviewed here the history of pediatric neurologic disorder classification and the role of genetics in the process. I also discussed the concept of clinical neurogenetics, with its role in clinical practice, education, and research. Finally, I propose a flexible model for clinical neurogenetics in child neurology in the twenty-first century. In combination with disorder-specific clinical programs, clinical neurogenetics can become a home for complex clinical issues, repository of genetic diagnostic advances, educational resource, and research engine in child neurology.

  15. Twenty-five years of post-Bretton Woods experience: some lessons

    Directory of Open Access Journals (Sweden)

    H. ASKARI

    1999-03-01

    Full Text Available In 1971 many academic economists were predicting that the Bretton Woods system of fixed parities would collapse. Some, most notably Milton Friedman, became excited about the possibility of a floating system because the benefits of international capital mobility can only be achieved through the flexibility in the exchange rate. These economists argued that a floating exchange rate system can ensure positive results more than the fixed parities system. Twenty-five years later, however, there is still no consensus on the matter. The author reviews the post-Bretton Woods experience to highlight some policies and approaches that might be helpful for the future.

    In most experimental studies, emotional pictures are widely used as stimulus material. However, there is still a lack of standardization of picture stimuli displaying erotic relationships, despite the association between a number of psychological problems and severe impairments and problems in intimate relationships. The aim of the study was to test a set of erotic stimuli, with the potential to be used in experimental studies, with heterosexual female subjects. Twenty International Affective Picture System (IAPS) pictures and an additional 100 pictures showing romantic but not explicitly sexual scenes and/or attractive single males were selected. All pictures were rated with respect to valence, arousal, and dominance by 41 heterosexual women and compared to pictures with negative, positive, and neutral emotional valence. Erotic IAPS pictures and our additional erotic pictures did not differ in any of the evaluation dimensions. Analyses of variance (ANOVAs) for valence, arousal, and dominance comparing different picture valence categories showed strong effects for category. However, valence was not significantly different between erotic and positive pictures, while arousal and control were not significantly different between positive and neutral pictures. The pictures of our new set are as positive for heterosexual women as highly positive IAPS pictures, but higher in arousal and dominance. The picture set can be used in experimental psychiatric studies requiring high numbers of stimuli per category. Limitations are the restriction of stimuli application to heterosexual females only and to self-report data. Copyright © 2011 Elsevier Ltd. All rights reserved.

    This study examines changes in personality traits in male and female dental students and recent graduates. The Comrey Personality Scales were administered to two freshman classes, and the test was readministered two months after graduation for one class and twenty-six months after graduation for the other class. Sex. class, and test/retest scores were analyzed using a three-way analysis of variance with repeated measures for each scale. Significant test/retest differences consisted of increases on the Orderliness versus Lack of Compulsion Scale and Conformity versus Rebelliousness Scale and a decrease on the Activity versus Lack of Energy Scale. There were significant sex differences on the Activity versus Lack of Energy, Emotional Stability versus Neuroticism, and Masculinity versus Femininity Scales; a decrease on the Empathy versus Egocentrism Scale occurred among females in one of the classes. Dental students became increasingly more orderly and identified with established social values; they also became less competitive and less driven to excel. The dental school experience may partially explain these changes; however, other conditions, such as maturation and societal influences, may have been involved.

    2018-01-22

    This article reviews the history of the treatment of women's sexual problems from the Victorian era to the twenty-first century. The contextual nature of determining what constitutes female sexual psychopathology is highlighted. Conceptions of normal sexuality are subject to cultural vagaries, making it difficult to identify female sexual dysfunctions. A survey of the inclusion, removal, and collapsing of women's sexual diagnoses in the Diagnostic and Statistical Manual of Mental Disorders from 1952 to 2013 illuminates the biases in the various editions. Masters and Johnson's models of sexual response and dysfunction paved the way for the diagnosis and treatment of women's sexual dysfunctions. Their sex therapy paradigm is described. Conceptions of and treatments for anorgasmia, arousal difficulties, vaginismus, dyspareunia, and low desire are reviewed. The medicalization of human sexuality and the splintering of sex therapy are discussed, along with current trends and new directions in sexual health care for women. Expected final online publication date for the Annual Review of Clinical Psychology Volume 14 is May 7, 2018. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

    2016-01-01

    Taking inspiration from Siv Cedering’s poem in the form of a fictional letter from Caroline Herschel that refers to “my long, lost sisters, forgotten in the books that record our science”, this book tells the lives of twenty-five female scientists, with specific attention to astronomers and mathematicians. Each of the presented biographies is organized as a kind of "personal file" which sets the biographee’s life in its historical context, documents her main works, highlights some curious facts, and records citations about her. The selected figures are among the most representative of this neglected world, including such luminaries as Hypatia of Alexandra, Hildegard of Bingen, Elisabetha Hevelius, and Maria Gaetana Agnesi. They span a period of about 4000 years, from En HeduAnna, the Akkadian princess, who was one of the first recognized female astronomers, to the dawn of the era of modern astronomy with Caroline Herschel and Mary Somerville. The book will be of interest to all who wish to learn more ...

One hundred nineteen women with infertility and 99 healthy female controls without infertility between the ages of 18 and 45 years were included in this study. Anonymous survey and Female Sexual Function Index. Female Sexual Function Index scores, frequency of sexual intercourse and masturbation, and sex-life satisfaction. Twenty-five percent of our control group had Female Sexual Function Index scores that put them at risk for sexual dysfunction (masturbation. The patients with infertility retrospectively reported a sex-life satisfaction score that was similar to that of the controls before their diagnosis, whereas their current sex-life satisfaction scores were significantly lower than those of the controls. Women with a diagnosis of infertility were found to be at higher risk for sexual dysfunction on the basis of their Female Sexual Function Index scores compared with women without infertility. The interaction of sexual function and infertility is complex and deserves further study. Copyright © 2010. Published by Elsevier Inc.

    Sprague-Dawley rats received once daily tail-vein injections of 360 mM dibasic sodium phosphate solution at 8 mL/kg for fourteen or twenty-eight days. Clinical examination revealed persistent proteinuria from three days after the first dosing and thereafter severe proteinuria from eight days or later in the phosphate-treated groups. Proteinuria developed without remission even after fourteen-day withdrawal in the fourteen-day dosed group. Phosphate-treated animals developed lipemia, hypercholesterolemia, anemia, higher serum fibrinogen levels, and lower serum albumin/globulin ratios on day 29. Renal weight increased significantly compared with control animals, and the kidneys appeared pale and enlarged with a rough surface. Histopathologically, glomerular changes consisted of mineralization in whole glomeruli, glomerular capillary dilatation, partial adhesion of glomerular tufts to Bowman's capsule, and mesangiolysis. Ultrastructural lesions such as an increased number of microvilli, effacement of foot processes, and thickening of the glomerular basement membrane, and immunocytochemical changes in podocytes, mainly decreased podoplanin-positive cells and increased desmin expression, were also conspicuous in the phosphate-treated rats for twenty-eight days. Marked tubulointerstitial lesions were tubular regeneration and dilatation, protein casts, mineralization in the basement membrane, focal interstitial inflammation, and fibrosis in the cortex. These clinical and morphological changes were similar to features of human nephrotic syndrome.

    Full Text Available The article investigated the geopolitical assessments of the results of the Summit of «Group of Twenty», which took place in Hangzhou from 4 till 5 September, 2016. The main idea of this event was the development of  innovation, healthy, coherent and inclusive economy. Moreover, important for the geopolitical consolidation of efforts of member countries in the context of further development of the world economy was making such documents as: Contours of the innovative growth of «Group of Twenty», Action plan of «Group of Twenty» in connection with a new industrial revolution, Hangzhou action plan, which set out a strategy for overall and confident growth and also initiative of «Group of twenty» in development and cooperation in the field of digital economy. Important thing is that analysis of the Summit’s results for world regions is important from a geopolitical point of view. We can predict that in the future geopolitical dialogue between the EU and the US in the economy will become more vital for both sides, and will enable to contribute to the implementation of more global challenges of the global economy. We should mention that Summit of «Group of Twenty» largely determined the prospects of global economic processes and build a new world economic order with the introduction of innovative approaches and elements of the digital economy. Activity on the functioning of the global economy should be based on the collective efforts of all participants and take into account all the realities on the international stage. No less important is that the Summit proved the presence of leading geopolitical centers that affect not only the balance of power in the world, but also the further development of key economic processes. Each of these centers sees its future not only the global economy but the global system as a whole as well as its geopolitical influence in certain regions and countries. On the one hand, as for the development of

    Data are presented on 240 female habitual self-mutilators. The typical subject is a 28-year-old Caucasian who first deliberately harmed herself at age 14. Skin cutting is her usual practice, but she has used other methods such as skin burning and self-hitting, and she has injured herself on at least 50 occasions. Her decision to self-mutilate is impulsive and results in temporary relief from symptoms such as racing thoughts, depersonalization, and marked anxiety. She now has or has had an eating disorder, and may be concerned about her drinking. She has been a heavy utilizer of medical and mental health services, although treatment generally has been unsatisfactory. In desperation over her inability to control her self-mutilative behavior this typical subject has attempted suicide by a drug overdose.

    2015-01-01

    Substantial progress has been made in recent years toward deciphering the molecular and genetic underpinnings of the pubertal process. The availability of powerful new methods to interrogate the human genome has led to the identification of genes that are essential for puberty to occur. Evidence has also emerged suggesting that the initiation of puberty requires the coordinated activity of gene sets organized into functional networks. At a cellular level, it is currently thought that loss of transsynaptic inhibition, accompanied by an increase in excitatory inputs, results in the pubertal activation of GnRH release. This concept notwithstanding, a mechanism of epigenetic repression targeting genes required for the pubertal activation of GnRH neurons was recently identified as a core component of the molecular machinery underlying the central restraint of puberty. In this chapter we will discuss the potential contribution of various mechanisms of epigenetic regulation to the hypothalamic control of female puberty. Copyright © 2014 Elsevier Inc.

    2014-12-01

    Full Text Available Most studies have examined pacing strategies with cyclical activities (running and cycling. It has been demonstrated that males employ different pacing strategies during repeated maximal voluntary contractions (MVCs dependent upon a known endpoint. Since different fatiguing mechanisms have been identified between the genders, it is not known if females use comparable pacing strategies. The purpose of this study was to examine if informing female subjects regarding the number of MVCs to perform would affect force and electromyography (EMG. Twenty well-trained females completed 3 fatiguing protocols in a randomized order. In the control condition participants were informed they would perform twelve MVCs and then actually completed twelve. In the unknown condition they were not told how many MVCs to perform but were stopped after twelve. In the deception condition they were initially informed to perform 6 MVCs, but after the 6th MVC they were asked to perform a few more MVCs and were stopped after twelve. During the first 6 MVCs, forces in the deception condition were greater compared to the unknown (p = 0.021, ES = 0.65, 5% and control (p = 0.022, ES = 0.42, 3% conditions. No differences were found between conditions in the last 6 MVCs. A main effect for repetitions showed force deficits during the first 6 MVCs (p = 0.000, ES = 1.81, 13% and last 6 MVCs (p = 0.05, ES = 0.34, 3%. No differences were found between conditions in biceps and triceps EMG. However, EMG decreased during the first 6 MVCs for biceps (p = 0.001, ES = 1.0, 14% and triceps (p = 0.001, ES = 0.76, 14% across conditions. No differences were found in the last 6 MVCs. The anticipation of performing fewer MVCs led to increased force, whereas no endpoint led to decreased force production.

    Full Text Available The evaluation of morphological differences among female judoka of different grades would make it possible to estimate the influence of motor activity in judo on athletes’ performances, leading to a more refined selection process in this sport. Therefore, this study aimed to compare the morphological characteristics of female judoka of different ranks. Twenty-three athletes of higher grades and thirty-two judoka of lower ranks participated in this study. We measured the lengths of six body segments and thecircumferences of twelve body segments, as well as nine skinfolds. We also evaluated body fat percentage. The mean differences between both groups were measured using ANOVA. This study shows that highly skilled judoka have significantly lower total body fat percentage (19.6 ± 4.4 and 22.7 ± 5.2 %, p < 0.05 and skinfold values (p < 0.05-0.01 in five body sites. They have significantly larger neck (34.4 ± 2.9 and 32.3 ± 2.4 cm, p < 0.01, thorax at forced inspiration (94.7 ± 5.1 and 91.4 ± 4.1 cm, p < 0.05 and expiration (88.6 ± 5.1 and 85.5 ± 4.4 cm, p < 0.05, and relaxed arm (27.8 ± 2.5 and 26.3 ± 2.1 cm, p < 0.05 circumferences. High-rank judoka have significantly longer hands (19.4 ± 1.3 and 18.1 ± 1.5 cm, p < 0.001 and significantly shorter thighs (37.2 ± 2.6 and 40.2 ± 3.2 cm, p < 0.001. Judoka with less body fat, more thoracic muscle mass, and shorter arms and legs are more successful in female judo.

    Surgery has been a male-dominated speciality both in South Africa and abroad. This mixed methodology case study collected data from a purposive sample of female surgical registrars enrolled at one institution in South Africa. A self-administered questionnaire was used to explore whether or not female doctors perceived any benefits of being in a male-dominated specialty. It explored problems encountered due to gender, the participants' perceptions of the influence of gender on their surgical training, practice and challenges. Thirty-two female registrars participated in the study. The respondents were mainly South African (91%) and enrolled in seven surgical specialities. Twenty-seven (84%) respondents were satisfied with their practical training and skills development as surgeons. Twenty-four (75%) respondents had identified a mentor from the department and all respondents indicated that the gender of their mentor did not impact on the quality of their training. Seventeen (53%) respondents perceived having received differential treatment due to their gender and 25 (78.2%) thought that the gender of their mentor did not impact on the quality of the guidance in surgery. Challenges included physical threats to them as females from patients and disrespect, emotional threats and defaming statements from male registrars. Other challenges included time-constraints for family and academic work, poor work life balance and being treated differently due to their gender. Seventeen (53%) respondents would consider teaching in the Department of Surgery. Twenty-five respondents (78%) would recommended the specialty to young female students, as they were convinced that surgery had been the right choice for them. Seventeen respondents (53%) were also open to pursuing teaching posts in the Department of Surgery. Generally, females had positive perceptions of their training in Surgery. They expressed concern about finding a worklife balance. The gender of their mentor did not impact

    Vitamin D deficiency is becoming endemic in many parts of the world. To study vitamin D status in Egyptian females of different age groups. A cross-sectional study was conducted on 404 females, who were categorized into group 1 (51 nursing females); group 2 (50 pregnant females); group 3 (208 females of childbearing age); group 4 (38 elderly females); and group 5 (57 geriatric females). Females completed a questionnaire regarding dietary calcium and vitamin D intake, sun exposure, and clothing habits, and performed laboratory tests including calcium, PO4, alkaline phosphatase, intact PTH, and 25-OH vitamin D levels. Median and IQR of vitamin D levels across groups 1, 2, 3 and 5 were in the deficient range, being lowest in groups 3, 5, and 1, respectively. Vitamin D deficiency was found in 72.6% of the nursing group, 54% of the pregnant group, 72% of the childbearing age group, 39.5% of the elderly group, and 77.2% of the geriatric group. Vitamin D was significantly higher in non-veiled females [23ng/dl] as compared to veiled females [16.7ng/dl]. Vitamin D levels with poor, fair, and good sun exposure were 14.1, 14, and 37ng/dl, respectively. These results show a high prevalence of vitamin D deficiency among healthy Egyptian females.

  19. Receptive females mitigate costs of sexual conflict.

    Harano, T

    2015-02-01

    Males typically gain fitness from multiple mating, whereas females often lose fitness from numerous mating, potentially leading to sexual conflict over mating. This conflict is expected to favour the evolution of female resistance to mating. However, females may incur male harassment if they refuse to copulate; thus, greater female resistance may increase costs imposed by males. Here, I show that the evolution of resistance to mating raises fitness disadvantages of interacting with males when mating is harmful in female adzuki bean beetles, Callosobruchus chinensis. Females that were artificially selected for higher and lower remating propensity evolved to accept and resist remating, respectively. Compared with females that evolved to accept remating, females that evolved to resist it suffered higher fitness costs from continuous exposure to males. The costs of a single mating measured by the effect on longevity did not differ among selection line females. This study indicates that receptive rather than resistant females mitigate the fitness loss resulting from sexual conflict, suggesting that even though mating is harmful, females can evolve to accept additional mating. © 2014 European Society For Evolutionary Biology.

    The chemical, bioactive, and antioxidant potential of twenty wild culinary mushroom species being consumed by the people of northern Himalayan regions has been evaluated for the first time in the present study. Nutrients analyzed include protein, crude fat, fibres, carbohydrates, and monosaccharides. Besides, preliminary study on the detection of toxic compounds was done on these species. Bioactive compounds evaluated are fatty acids, amino acids, tocopherol content, carotenoids (β-carotene, lycopene), flavonoids, ascorbic acid, and anthocyanidins. Fruitbodies extract of all the species was tested for different types of antioxidant assays. Although differences were observed in the net values of individual species all the species were found to be rich in protein, and carbohydrates and low in fat. Glucose was found to be the major monosaccharide. Predominance of UFA (65–70%) over SFA (30–35%) was observed in all the species with considerable amounts of other bioactive compounds. All the species showed higher effectiveness for antioxidant capacities. PMID:26199938

    1978-01-01

    Twenty-five years have passed since the European Coal and Steel commmunity was established. An attempt is made to show what economic integration is, what problems have arisen, and how the community has tried to overcome them. Three phases can be distinguished during the period under review--a first phase of growth in the coal industry between 1953 and 1957; a second phase marked by a plentiful supply of cheap hydrocarbons and a rapid reduction in coal output despite exceptional growth, linked with a parallel increase in overall energy requirements; and a third phase from 1973, marked by sharp price increases by the oil producing countries with repercussions on the world market in coal.

    Full Text Available This is a broad examination of the issue of youth violence in twenty-first-century Africa, looking at the context within which a youth culture of violence has evolved and attempting to understand the underlining discourses of hegemony and power that drive it. The article focuses specifically on youth violence as apolitical response to the dynamics of (disempowerment, exclusion, and economic crisis and uses (postconflict states like Liberia, Sierra Leone, and Nigeriato explain not just the overall challenge of youth violence but also the nature of responses that it has elicited from established structures of authority. Youth violence is in many ways an expression of youth agency in the context of a social and economic system that provides little opportunity.

  9. Ecological restoration should be redefined for the twenty-first century.

    2017-09-24

    Forty years ago, ecological restoration was conceptualized through a natural science lens. Today, ecological restoration has evolved into a social and scientific concept. The duality of ecological restoration is acknowledged in guidance documents on the subject but is not apparent in its definition. Current definitions reflect our views about what ecological restoration does but not why we do it. This viewpoint does not give appropriate credit to contributions from social sciences, nor does it provide compelling goals for people with different motivating rationales to engage in or support restoration. In this study, I give a concise history of the conceptualization and definition of ecological restoration, and I propose an alternative definition and corresponding viewpoint on restoration goal-setting to meet twenty-first century scientific and public inquiry.

    Invasive alien species (IAS) threaten human livelihoods and biodiversity globally. Increasing globalization facilitates IAS arrival, and environmental changes, including climate change, facilitate IAS establishment. Here we provide the first global, spatial analysis of the terrestrial threat from IAS in light of twenty-first century globalization and environmental change, and evaluate national capacities to prevent and manage species invasions. We find that one-sixth of the global land surface is highly vulnerable to invasion, including substantial areas in developing economies and biodiversity hotspots. The dominant invasion vectors differ between high-income countries (imports, particularly of plants and pets) and low-income countries (air travel). Uniting data on the causes of introduction and establishment can improve early-warning and eradication schemes. Most countries have limited capacity to act against invasions. In particular, we reveal a clear need for proactive invasion strategies in areas with high poverty levels, high biodiversity and low historical levels of invasion. PMID:27549569

    Niels Bohr and Philosophy of Physics: Twenty-First Century Perspectives examines the philosophical views, influences and legacy of the Nobel Prize physicist and philosophical spokesman of the quantum revolution, Niels Bohr. The sixteen contributions in this collection by some of the best contemporary philosophers and physicists writing on Bohr's philosophy today all carefully distinguish his subtle and unique interpretation of quantum mechanics from views often imputed to him under the banner of the “Copenhagen Interpretation.” With respect to philosophical influences on Bohr's outlook, the contributors analyse prominent similarities between his viewpoint and Kantian ways of thinking, the views of the Danish philosopher Harald Høffding, and themes characteristic of American pragmatism. In recognizing the importance of Bohr's epistemological naturalism they examine his defence of the indispensability of classical concepts from a variety of different perspectives. This collection shows us that Bohr's int...

    At the beginning of the twenty-first century, there are 30,000 golf courses and 55 million people who play golf worldwide. In the USA alone, the value of golf club memberships sold in the 1990s was US dollar 3.2 billion. Underpinning this significant human activity is a wide variety of people researching and applying science to sustain and develop the game. The 11 golf science disciplines recognized by the World Scientific Congress of Golf have reported 311 papers at four world congresses since 1990. Additionally, scientific papers have been published in discipline-specific peer-reviewed journals, research has been sponsored by the two governing bodies of golf, the Royal and Ancient Golf Club of St. Andrews and the United States Golf Association, and confidential research is undertaken by commercial companies, especially equipment manufacturers. This paper reviews much of this human endeavour and points the way forward for future research into golf.

    To improve health in the twenty-first century, to promote both access to and quality of health care services and delivery, and to address significant health disparities, legal and policy approaches, specifically those focused on civil rights, could be used more intentionally and strategically. This review describes how civil rights laws, and their implementation and enforcement, help to encourage health in the United States, and it provides examples for peers around the world. The review uses a broad lens to define health for both classes of individuals and their communities--places where people live, learn, work, and play. Suggestions are offered for improving health and equity broadly, especially within societal groups and marginalized populations. These recommendations include multisectorial approaches that focus on the social determinants of health.

    Microsatellite markers were identified for Melastoma tetramerum var. tetramerum (Melastomataceae), a critically endangered shrub endemic to the Bonin Islands, to reveal genetic characteristics in wild and restored populations. Using next-generation sequencing, 27 microsatellite markers were identified. Twenty of these markers were polymorphic in M. tetramerum var. tetramerum, with two to nine alleles per locus and expected heterozygosity ranging from 0.10 to 0.71. Among the 20 polymorphic markers, 15 were applicable to other closely related taxa, namely M. tetramerum var. pentapetalum, M. candidum var. candidum, and M. candidum var. alessandrense. These markers can be potentially useful to investigate the genetic diversity, population genetic structure, and reproductive ecology of M. tetramerum var. tetramerum as well as of the three related taxa to provide appropriate genetic information for conservation.

    Europe faces a great challenge with the 2020 scenario in which the renewable energy installed capacity in Europe should increase from its present value of approximately 80 GW to 230 GW in 2020. The future high penetration levels of wind and other renewable energies in the power system require decision makers and stakeholders of the electrical sector to work together to develop new ancillary services and to make the necessary changes to the grid infrastructure in Europe. This background is in line with the SYSERWIND demonstration lead by Iberdrola Renovables and included in the TWENTIES project, with three more partners taking part in this package: Red Electrica de Espana (REE), IIT and Gamesa Eolica. This paper introduces a first phase of preliminary work to define, install and test a Secondary Frequency Control and a Voltage Management System in a wide area, along a transport line. (orig.)

  17. Uncertainty in Twenty-First-Century CMIP5 Sea Level Projections

    The representative concentration pathway (RCP) simulations included in phase 5 of the Coupled Model Intercomparison Project (CMIP5) quantify the response of the climate system to different natural and anthropogenic forcing scenarios. These simulations differ because of 1) forcing, 2) the representation of the climate system in atmosphere-ocean general circulation models (AOGCMs), and 3) the presence of unforced (internal) variability. Global and local sea level rise projections derived from these simulations, and the emergence of distinct responses to the four RCPs depend on the relative magnitude of these sources of uncertainty at different lead times. Here, the uncertainty in CMIP5 projections of sea level is partitioned at global and local scales, using a 164-member ensemble of twenty-first-century simulations. Local projections at New York City (NYSL) are highlighted. The partition between model uncertainty, scenario uncertainty, and internal variability in global mean sea level (GMSL) is qualitatively consistent with that of surface air temperature, with model uncertainty dominant for most of the twenty-first century. Locally, model uncertainty is dominant through 2100, with maxima in the North Atlantic and the Arctic Ocean. The model spread is driven largely by 4 of the 16 AOGCMs in the ensemble; these models exhibit outlying behavior in all RCPs and in both GMSL and NYSL. The magnitude of internal variability varies widely by location and across models, leading to differences of several decades in the local emergence of RCPs. The AOGCM spread, and its sensitivity to model exclusion and/or weighting, has important implications for sea level assessments, especially if a local risk management approach is utilized.

  18. Twenty-first century learning after school: the case of Junior Achievement Worldwide.

    Box, John M

    2006-01-01

    Efforts to increase after-school programming indicate the nation's concern about how youth are engaged during out-of-school time. There are clear benefits to extending the learning that goes on during the school day. Research from the U.S. Departments of Education and Justice shows that after-school participants do better in school and have stronger expectations for the future than youth who are not occupied after school. And the need is evident: 14.3 million students return to an empty house after school, yet only 6.5 million children are currently enrolled in after-school programs. If an after-school program were available, parents of 15.3 million would enroll their child. JA Worldwide began in 1919 and has been rooted in the afterschool arena from its origins. Its after-school programs teach students about the free enterprise system through curriculum focusing on business, citizenship, economics, entrepreneurship, ethics and character, financial literacy, and career development. At the same time, JA Worldwide incorporates hands-on learning and engagement with adults as role models, both key elements to a successful after-school program. Now focused on developing curriculum emphasizing skills needed for the twenty-first century, JA adopted the key elements laid out for after-school programs by the Partnership for 21st Century Skills. To ensure that the next generation of students enters the workforce prepared, America's education system must provide the required knowledge, skills, and attitudes. Programs such as JA Worldwide serve as models of how to provide the twenty-first century skills that all students need to succeed.

    Brain injuries occurring at a particular time may cause damages in well-defined regions of brain. Perinatal hypoxic ischemic encephalopathy and hypoglycemia are some of the most common types of brain injuries. Neonatal hypoglycemia can cause abnormal myelination in parietal and occipital lobes resulting in parieto-occipital encephalomalacia. There is a small number of studies about clinical and electroencephalographic (EEG) features of children with parieto-occipital encephalomalacia. They might have important neurologic sequelae such as cortical visual loss, seizures, and psychomotor retardation. We aimed to evaluate the causes of parieto-occipital encephalomalacia and evaluate the clinical and electrophysiological features of children with parieto-occipital encephalomalacia. We evaluated clinical features and EEGs of 27 children with parieto-occipital encephalomalacia. Descriptive statistics were used. Hospitalization during the neonatal period was the most common cause (88.9%) of parieto-occipital brain injury. Eleven patients (40.7%) had a history of neonatal hypoglycemia. Twenty-three patients (85.2%) had epilepsy and nine of the epileptic patients (39%) had refractory seizures. Most of the patients had bilateral (50%) epileptic discharges originating from temporal, parietal, and occipital lobes (56.2%). However, some patients had frontal sharp waves and some had continuous spike and wave discharges during sleep. Visual abnormalities were evident in 15 (55.6%) patients. Twenty-two (81.5%) had psychomotor retardation. Fine motor skills, social contact and language development were impaired more than gross motor skills. In our study, most of the patients with parieto-occipital encephalomalacia had an eventful perinatal history. Epilepsy, psychomotor retardation, and visual problems were common neurologic complications.

  20. Twenty-first century learning in states: the case of the Massachusetts educational system.

    Science.gov (United States)

    Driscoll, David P

    2006-01-01

    A current crisis in education is leaving students less prepared to succeed in the working world than any generation before them. Increasingly complex external, nonacademic pressures have an impact on many of today's students, often causing them to drop out of school. Only 76 percent of Massachusetts high school students graduate, and only 29 percent earn a college degree. National figures are worse. Most educational institutions share a common goal to support students in becoming skilled, productive, successful members of society, but the author argues that this goal is not being met. Despite the constant changes in the world, educational practices have remained static. Most public schools are not adapting to meet the shifting needs of students. Universities are not able to prepare the right mix of prospective employees for the demands of the job market; for example, schools are graduating only 10 percent of the needed engineers. Institutions of higher learning cannot keep up with employers' needs in an evolving global market: strong math, science, and writing abilities; critical thinking skills; and the ability to work in teams. The author draws on exemplary efforts at work in his home state of Massachusetts--whose improvements in student achievement outcomes have been some of the best in the nation--to suggest there is promise in twenty-first century learning. Middle school students involved in a NASA-funded project write proposals, work in teams, and engage in peer review. Older students participate in enhanced, hands-on cooperative school-to-work and after-school programs. Schools are starting to offer expanded day learning, increasing the number of hours they are engaged in formal learning. Yet such programs have not reached significant levels of scale. The author calls for a major shift in education to help today's students be successful in the twenty-first century.

    This study aimed to delineate the anthropometric measurements of the noses of young women of an Indian population and to compare them with the published ideals and average measurements for white women. This anthropometric survey included a volunteer sample of 100 young Indian women ages 18 to 35 years with Indian parents and no history of previous surgery or trauma to the nose. Standardized frontal, lateral, oblique, and basal photographs of the subjects' noses were taken, and 12 standard anthropometric measurements of the nose were determined. The results were compared with published standards for North American white women. In addition, nine nasal indices were calculated and compared with the standards for North American white women. The nose of Indian women differs significantly from the white nose. All the nasal measurements for the Indian women were found to be significantly different from those for North American white women. Seven of the nine nasal indices also differed significantly. Anthropometric analysis suggests differences between the Indian female nose and the North American white nose. Thus, a single aesthetic ideal is inadequate. Noses of Indian women are smaller and wider, with a less projected and rounded tip than the noses of white women. This study established the nasal anthropometric norms for nasal parameters, which will serve as a guide for cosmetic and reconstructive surgery in Indian women.

    Sexual behavior is a result of interaction of biology and psychology. Sexual excitement of the female can be triggered by stimulation of erotogenic areas; part of which is the clitoris. Female circumcision is done to minimize sexual desire and to preserve virginity. This procedure can lead to psychological trauma to the child; with anxiety, panic attacks and sense of humiliation. Cultural traditions and social pressures can affect as well the unexcised girl. Female circumcision can reduce fem...

    2012-01-01

    This study was designed to evaluate the knowledge and attitude of a cohort of Iranian community pharmacists about the pharmaceutical care indexes and drug therapy in female epileptic patients. Methodology: This cross-sectional study was conducted in Iran (2011) and one hundred and twenty two community pharmacists were randomly selected using clustering method for sampling. A self-administered questionnaire which was originally made by a clinical pharmacy focus group was used. This questionnaire had 10 true/false questions for knowledge assessing (Spearman-Brown coefficient, 0.65) and 19 attitude statements (with Likert scale) about the intention of pharmacists for providing pharmaceutical care for epileptic females (Croanbach's alpha, 0.802). Face and content validity for both parts of the questionnaire were performed before the study. Results: There was a significant inverse relationship between pharmacists' knowledge on pharmaceutical care for epileptic females and the time elapsed from their graduation date. Considering the minimum passing score of 5, 85% of pharmacists did not have enough knowledge. The range of pharmacists' attitude scores was 35 to 64 and its mean was 46.09. Regarding the minimum passing score of 45, 63.3% of pharmacists had positive attitude to AEDs in epileptic females. Conclusion: It seems that the pharmaceutical care for epileptic females is a missing part of Pharmacy education. It is highly recommended to pay special attention to this topic in continuing education programs for Iranian pharmacists. (author)

    Traditional health education may not provide adequate sexual information to female adolescents. Sexual health education for female adolescents broadens opportunities for nurses to help female adolescents adopt appropriate sexual attitudes and make appropriate decisions. The purpose of this study was to understand the effect of sexual empowerment on sexual decision making in female adolescents. Twenty-nine female students with steady boyfriends were invited to participate in a sexual empowerment course. Course activities specifically related to sexual empowerment were audio-tape-recorded. Dialogue content was analyzed, and content provided by each study participant was reconfirmed in face-to-face interviews to understand the entire empowerment process in terms of how such may affect responses and to assess the possibility of correctly reinterpreting findings during the member check process. This study also took into consideration degrees of reliability and rigorousness. The four themes found to underlie participant perceptions of their sexual empowerment to make sex-related decisions were as follows: (a) proactively seeking sexual knowledge, (b) reexamining relationships with boyfriends, (c) the right to say "no" and to engage in self-protection, and (d) the need to change sexual attitudes and behaviors. Using the peer group intervention in sexual empowerment may positively impact sexual health decision making in adolescent girls. Nursing professionals may consider peer group intervention as a sexual empowering method in healthcare.

    The twenty-one item Stress Measurement of Female Marriage Immigrants (SMFMI) was developed to assess stress of female marriage immigrants in Korea. This study reports the psychometric properties of a revised SMFMI (SMFMI-R) for application with female marriage immigrants to Korea who were raising children. Participants were 190 female marriage immigrants from China, Vietnam, the Philippines, and other Asian countries, who were recruited using convenience sampling between November 2013 and December 2013. Survey questionnaires were translated into study participants' native languages (Chinese, Vietnamese, and English). Principal component analysis yielded nineteen items in four factors (family, parenting, cultural, and economic stress), explaining 63.5% of the variance, which was slightly better than the original scale. Confirmatory factor analysis indicated adequate fit for the four-factor model. Based on classic test theory and item response theory, strong support was provided for item discrimination, item difficulty, and internal consistency (Cronbach's alpha = 0.923). SMFMI-R scores were negatively associated with Korean proficiency and subjective economic status. The SMFMI-R is a valid, reliable, and comprehensive measure of stress for female marriage immigrants and can provide useful information to develop intervention programs for those who may be at risk for emotional stress.

    The hairdressing occupation may entail exposure to a wide range of chemical products, psychosocial and physical stress. All these factors may affect the health of a pregnant hairdresser and her offspring. Our aim was to analyse whether employment in this profession is associated with adverse reproductive effects. Female hairdressers working in the 248 hairdressing salons in Alicante (Spain), who became pregnant for the first time after 1990 were included (n = 94). The incidence of spontaneous abortions, number of children born and their birth weight and preterm delivery among hairdressers was compared with a control group of shop assistants and office workers (n = 138). Information was collected through personal interviews at their work place. A structured questionnaire was used gathering information concerning exposure variables including the use of chemical products, ventilation at the salons, work-related stress and hours of standing work. In addition, socio-demographic factors and smoking information were obtained. Crude and adjusted relative risks (RR) and 95% confidence intervals (95%CI) were calculated using logbinomial regression. Hairdressers showed a non-significant increased risk of spontaneous abortions (RR = 1.6, 95%CI 0.9-2.7). There were no differences in preterm delivery and birth weight of the children born of mothers in the two groups. Among hairdressers, the RR of spontaneous abortion among those with high perceived work-related stress was 2.4 (95%CI: 0.2-28.3) relative to those with low or normal perceived stress. A slightly increased risk of spontaneous abortion among hairdressers was found, mainly associated with perceived work-related stress. Observed results deserve further research.

  11. The evolution of female sex pheromones

    Full Text Available The role of female sex pheromones in natural selection, particularly as a means for species recognition to avoid the generation of hybrid offspring with low fitness, has been widely explored and is generally accepted by scholars. However, the significance of sex pheromones in shaping mate choice (sexual selection and in competition over breeding resources (social selection has been largely ignored. The effect of sexual selection on sex pheromones as a sexually dimorphic signaling trait has been discounted because the amount of pheromone released by females is typically minute, while the role of sex pheromones in competition over breeding resources (other than mates has not yet been considered. As a result of natural selection, variation in sex pheromones among females is expected to be low, and males are not expected to choose their mates among pheromone-releasing conspecific females. Sexual selection, on the other hand, should drive the increase in pheromone variance among females, and males are expected to choose females based on this variation. Moreover, social selection resulting from more general social interactions, for example competition among females for breeding sites and food, should also promote variance among female sex pheromones. Here, we review the current evidence for each of the three selection processes acting on sex pheromones of female moths as an advertising trait. We suggest that the three selection types are not mutually exclusive but rather act together to promote different fitness components in diverse ecological situations [Current Zoology 59 (4: 569–578, 2013].

    Inadequate dietary intake is the primary nutritional concern of today's female athlete. As these athletes fail to consume enough energy to support the physical demands of training, they become at risk for disordered eating, amenorrhea, and osteoporosis, conditions collectively identified as the female athlete triad. This review addresses nutritional concerns of the female athlete, identification of those at risk, relationship of energy intake to menstrual irregularities, and recently identified chronic diseases associated with the female athlete triad. Strategies are offered to prevent harmful behaviors leading to the comorbidities associated with inadequate dietary intakes.

    Morphological and geometric differences between male and female feet can be the decisive factor of whether well-fitting, functional, and comfortable footwear is available for both men and women. Optical scans, plaster wrap casts, and a set of manual measurements from the right feet of 51 female participants, aged 20 to 59 years (32 +/- 10.2 years), and 39 male participants, aged 22 to 71 years (47.1 +/- 12.1 years), were taken to determine which parameters were the most significant in characterizing pedal geometry and which had the largest difference between male and female feet. Analysis showed that the heel-to-ball length (ball length) of the male participants' feet (181.5 mm) was significantly longer, on average, than that of the female participants' feet (165.0 mm). The width of the male paticipants' feet at the ball, instep, and heel regions, as well as the ball circumference, normalized by the ball length, were all significantly larger on average, than the female test participants' feet. However, toe region, instep, and medial and lateral malleoli heights were larger, on average, for the female participants than for the male. The results show that female feet differ in size and shape from male feet and are not algebraically scaled, smaller versions of male feet, as is often assumed. The study shows that the average male participants' feet are longer than that of the female participants' feet, while the female feet are relatively narrower but higher than those of the male participants.

    Full Text Available The paper explores, in the context of feminist discussions about the Bildungsroman, a contemporary British novel that offers shocking images of female coming of age at the turn of the millennium. Queering gender and introducing male elements into the heroine’s process of maturation, the analysed novel appears to raise questions about the continuous relevance of the feminist distinction between male and female version of the genre. The paper however argues that although significantly rewriting both female Bildung and pornographic narratives, Helen Walsh’s Brass can still be read as a variation of the female Bildungsroman and an example of its contemporary developments.

  17. Twenty-first century learning in schools: A case study of New Technology High School in Napa, California.

    2006-01-01

    The most pertinent question concerning teaching and learning in the twenty-first century is not what knowledge and skills students need--that laundry list was identified over a decade ago--but rather how to foster twenty-first century learning. What curricula, experiences, assessments, environments, and technology best support twenty-first century learning? New Technology High School (NTHS) in Napa, California, is one example of a successful twenty-first century school. In this chapter, the author describes the components of this exemplary high school, illustrating an environment that will cultivate twenty-first century student learning. New Technology High School began by defining eight learning outcomes, aligned with the standards of the Partnership for 21st Century Skills; to graduate, students demonstrate mastery of these outcomes through an online portfolio. To help students achieve the outcomes, NTHS employs project- and problem-based learning. Whereas in traditional classrooms students work alone on short-term assignments that do not lend themselves to deep understanding, the project-based learning approach has students working in teams on long-term, in-depth, rigorous projects. Students' work is supported by the school's workplace-like environment and effectiv use of technology. Meaningful assessment is essential to project-based learning; students receive continuous feedback, helping them become self-directed learners. In fact, NTHS uses outcome-based grading through which students constantly know how they are performing on the twenty-first century outcomes. Research has shown that NTHS graduates are better prepared for postsecondary education, careers, and citizenship than their peers from other schools. To facilitate twenty-first century learning, all schools need to rethink their approach to teaching and learning. New Technology High School is one way to do so.

  18. The female condom: controlled by women.

    Science.gov (United States)

    1995-09-01

    The polyurethane female condom is stronger than the latex male condom. Thus, the single-use female condom is less likely to break and has a longer shelf life than the single-use male condom. The ring at the closed end of the condom helps women insert the condom and secures the condom inside the vagina. The outer ring remains outside the vagina and protects the labia and the base of the penis. Female condom use reduces the likelihood of transmission of infectious diseases. The female condom is as effective at preventing pregnancy as the male condom and the diaphragm. Its life-table pregnancy rate in a multicenter clinical trial in the US and Latin America was 15.1% (12.4% in US and 22.% in Latin America). The 6-month failure rate during perfect use was 4.3%. In laboratory studies, no sexually transmitted organism, including HIV, penetrated the female condom. In a human use study, 14% of controls and 14.7% of non-perfect users were reinfected with trichomonas while none of the perfect users were reinfected. Advantages of the female condom follow: allows for greater sensitivity and greater protection than the male condom, is controlled by the female, can be used with any lubricant (even oil-based lubricants), and can be inserted well before intercourse. Disadvantages include cost (5 times costlier than the male condom), unsightly coverage of female genitalia, noisy during use, and breakage (although breakage rates were lower than for latex condoms: 1% vs. 2-5%). Method acceptability studies among various populations show that the inner rings and movement of the female condom during use were the most common complaints. Many women liked the female condom and would recommend it to others. Only a few women complained about insertion problems, yet it took some women at least two tries to insert the female condom.

    Background The pursuit of sexual pleasure is a key motivating factor in sexual activity. Many things can stand in the way of sexual orgasms and enjoyment, particularly among women. These are essential issues of sexual well-being and gender equality. Objective This study presents long-term trends and determinants of female orgasms in Finland. The aim is to analyze the roles of factors such as the personal importance of orgasms, sexual desire, masturbation, clitoral and vaginal stimulation, sexual self-esteem, communication with partner, and partner’s sexual techniques. Design In Finland, five national sex surveys that are based on random samples from the central population register have been conducted. They are representative of the total population within the age range of 18–54 years in 1971 (N=2,152), 18–74 years in 1992 (N=2,250), 18–81 years in 1999 (N=1,496), 18–74 years in 2007 (N=2,590), and 18–79 years in 2015 (N=2,150). Another dataset of 2,049 women in the age group of 18–70 years was collected in 2015 via a national Internet panel. Results Contrary to expectations, women did not have orgasms that are more frequent by increasing their experience and practice of masturbation, or by experimenting with different partners in their lifetime. The keys to their more frequent orgasms lay in mental and relationship factors. These factors and capacities included orgasm importance, sexual desire, sexual self-esteem, and openness of sexual communication with partners. Women valued their partner’s orgasm more than their own. In addition, positive determinants were the ability to concentrate, mutual sexual initiations, and partner’s good sexual techniques. A relationship that felt good and worked well emotionally, and where sex was approached openly and appreciatively, promoted orgasms. Conclusion The findings indicate that women differ greatly from one another in terms of their tendency and capacity to experience orgasms. The improvements in gender

  1. Female sexuality, regulation and resistance.

    India was the context for this discussion of female sexuality, rigid social norms, women's strategies for resistance, the evolution of norms from colonial India, prostitution, myths, and self-help women's activities. Sexuality is a changing set of ideas, and women have contributed to the redefinition. The biological view without consideration of the sociocultural and historical influences proscribes what is deviant and may be used to reinforce patriarchy and colonialism. Management and control of sexuality has been influenced by class, religion, caste, and ethnicity. During the colonial period, women's sexuality and treatment was challenged by the missionaries. The abolishment of "sati" as a traditional practice was used by the British to expand their rule and control over a wider regional area. Attempts were also made to regulate prostitution as means of protecting the health of the British army. The law requiring registration, examination, and commitment for treatment of prostitutes was not adhered to by the women involved. The notion of mothers as irresponsible came into being about 1900, and encouraged abandonment of traditional child- rearing ways for the Western standard of health and hygiene, and lifestyle. In Bengal, motherhood and mother qoddesses became the symbol of the liberation movement. The maternal role could be strengthened through education. The notion of mother and nationhood was supported by the women's movement in Great Britain and the US through positive eugenics ideas of quality race, which supported the ruling elite of British and Indians. Thus, the high class women were to be protected from early marriage, and encouraged to produce children fit to govern; the poor were to be protected from prostitution and overpopulation. Post colonial ideas about sexuality reflected a number of influences both from within and outside India. Health was a focus, and program targets were those who were outside the norm: women with too many children

    We present a retrospective study of 25 patients with spontaneous pneumothorax (three recurrent) comprising 16 Saudis (nine males and seven females) and eight non-Saudi's (eight males and one female), seen at the Asir Central Hospital, Abha, over a period of 45 months. Almost one-third of patients (9/25) had no underlying cause discernible by our investigational facilities (chest x-ray, ultrasonography, computed tomographic scan and flexible bronchofiberscopy). Underlying pneumonia (three patients), pulmonary tuberculosis (two patients), lung abscess (one patient) and congenital bullae (one patient) constituted the etiology in another third of the spontaneous pneumothorax patients. Other underlying pulmonary diseases, precipitating spontaneous pneumothorax in the group included pulmonary fibrosis, metastatic mesothelioma and immunosuppression in a medulloblastoma patient undergoing chemotherapy with the development of chickenpox. Closed thoracostomy tube drainage was the only method of treatment in 20 out of 25 patients, with three failures of closed thoracostomy tube drainage needing thoractomy and resection of blebs/bullae. The only complication was empyema in two of the patients. Two patients were successfully treated conservatively with observation alone. (author)

    Objective: To summarize the clinical characteristics of idiopathic pulmonary fibrosis (IPF). Methods: The clinical characteristics of twenty-eight cases diagnosed as IPF between 1991 and 2006 were studied retrospectively. Results: Most IPF patients had an insidious onset of progressive dyspnea and non-productive cough. Inspiratory crackles and finger clubbing were also noted in most patients. The most impressive appearance of their radiography was peripheral reticular and nodular opacities, distributed largely at the lung bases. Pulmonary function test showed restrictive impairment and impaired oxygen diffusion. The arterial blood gas analysis revealed type I respiratory failure. One IPF case was complicated with lung cancer. The symptoms of fifteen cases(71.4%) were relieved under the therapy with glucocorticoid. Seven patients died as yet in our group and the middle duration was 24 months. Conclusions: The diagnosis of IPF relies mostly on the clinical characteristics, radiography, pulmonary function test, blood gas analysis and exclusion of other ILD. Atypical cases need lung biopsy to do further the diagnosis. Therapy with glucocorticoid may be effective in some cases. Prognosis in IPF cases complicated with lung cancer is poor. (authors)

    Full Text Available Twenty years ago, reading culture, library skills’ development used to be one of the core directions in research and teaching policy of the Department of Library Science at Vilnius University. Lateron, the topic was marginalized and today we return to the field that meanwhile has developed huge knowledge and experience base worldwide. A stimulus for the return was participation in BIBLIONOVA project. The aim of the article is to present a holistic approach towards information competency development in a modern academic institution. Prescriptive approach based on information literacy standards proved to be limited and not always effective in the academic environment.Information competency development is problem-specific, domain-specific, and disciplinespecific. It is interrelated with critical thinking, analytical skills as well as creativity and computerliteracy skills. Holistically, information competency development is an integral part of university’s life-long learning strategy. Critical success factors for information competency development areopen and problem-based learning and cooperative, inclusive strategies of the whole university. Academic libraries continue to play a major role in the process but the connections with faculty and administration in the process are of major importance.

    A liquid chromatography-tandem mass spectrometry method using a pentafluorophenylpropyl-bonded silica column was developed to simultaneously quantify twenty Amadori products (APs), including N-(1-Deoxy-d-fructosyl-1-yl)-l-isoleucine (Fru-Ile) and N-(1-Deoxy-d-fructosyl-1-yl)-l-leucine (Fru-Leu), in soy sauce, without the need for an ion-pairing reagent or sample derivatization. The method was applied to six types of soy sauce, to determine the total AP levels and the levels of individual APs. The level of total APs widely varied between the eight samples, from 358mg/L to 24347mg/L. The concentrations of N-ε-(1-deoxy-d-fructosyl-1-yl)-l-lysine (Fru-Lys) and N-(1-deoxy-d-fructosyl-1-yl)-l-pyroglutamic acid (Fru-pGlu) were the highest among the APs and the level of Fru-pGlu was similar to that of Fru-Lys. Furthermore, fermentation periods of up to six months greatly influenced AP levels in soy sauce but the levels remained constant thereafter. Thermal treatment of soy sauce had little effect on AP levels. Copyright © 2017. Published by Elsevier Ltd.

    Summary Background and objectives Pre- or postdialysis BP recordings are imprecise, can be biased, and have poor test–retest reliability in children on dialysis. We aimed to examine the possible differences between pre- and postdialysis BP levels and 24-hour ambulatory BP monitoring (ABPM) in diagnosis of hypertension (HTN). Design, setting, participants, & measurements Twenty-four children on dialysis had 24-hour ABPM in the interdialytic period, and values were compared with average pre- and postdialysis systolic BP (SBP) and diastolic BP (DBP) recordings that week. Each patient had an echocardiogram to determine presence of left ventricular hypertrophy (LVH). Results By ABPM, 8% of patients had white coat HTN and 12% had masked HTN. There was no significant difference in diagnosis of systolic HTN based on ABPM daytime SBP mean or load and postdialysis SBP. However, only 15% of patients had diastolic HTN based on postdialysis measures, whereas 46% of patients had significantly elevated daytime DBP loads and 71% had high nighttime DBP loads on ABPM. Forty-eight percent of patients were SBP nondippers. Children with LVH had higher daytime and nighttime SBP loads, significantly higher daytime and nighttime DBP loads, and lesser degree of nocturnal dipping of SBP compared with those who did not. Conclusion ABPM is more informative than pre- and postdialysis BPs and improves the predictability of BP as a risk factor for target organ damage. Diagnosis and treatment monitoring of HTN among pediatric dialysis patients is enhanced with addition of ABPM. PMID:21273374

  7. Twenty years research of chronic gamma-ray irradiation on seed crops

    1983-01-01

    Twenty years of the works on the chronic gamma-ray irradiation of seed crops are summarized. Radiosensitivity and the mutation rate per unit exposure varies not only with the genetic factor but also depend on whether treatment is given to seeds or growing plants. The relation between the radiosensitivity of seeds and growing plants also varies with plant species. In Hordeum, Avena and Nicotiana, the highest mutation rate obtained by the chronic irradiation of growing plants is similar to that in seed irradiation, but in Oryza and Setalia, chronic irradiation was two to three times more effective for attaining a higher mutation rate. The mutation spectrum also varies with the mutagen, the factors modifying the effects of mutagen, and the dose of mutagen. The suitability of a particular mutagenic treatment to a species should be taken into consideration in the evaluation of mutagenic treatment. For instance, NaN 3 is highly mutagenic to barley, but less mutagenic to rice. The gene ea7 controlling the maturing earliness of barley seems to be mutable in chronic irradiation, and the mutants obtained by chronic irradiation are healthy. The author emphasized that the chronic irradiation at the gamma-field is a useful mutagenic treatment, even though some negative results have been reported in European countries. (Kaihara, S.)

    Full Text Available The hypopigmented variant of mycosis fungoides (MF is charactrized by the presence of hypopigmented patches as the sole manifestation of the disease. This variant is usually observed in the dark skin of African or Asian individuals particularly children, but nevertheless is an uncommonly reported presentation of the disease. The incidence of hypopigmented MF in Caucasian patients and others of fair skin color is rare. We describe hypopigmented lesions arising in a twenty-year-old Saudi woman with type IV skin color. The diagnosis of mycosis fungoides stage IA was made based on the clinico-radiological and histological features. The patient responded well to PUVA therapy and is currently clear of lesions. MF should be considered in the differential diagnosis of hypopigmented macular lesions in patients of any skin color and age. Multiple skin biopsies must be performed on different occasions so as not to miss the diagnosis; and long term follow up is recommended since recurrence is common and occasional cases behave aggressively.

  10. Tuning up mind's pattern to nature's own idea: Eddington's early twenties case for variational derivatives

    Science.gov (United States)

    Smadja, Ivahn

    This paper sets out to show how Eddington's early twenties case for variational derivatives significantly bears witness to a steady and consistent shift in focus from a resolute striving for objectivity towards "selective subjectivism" and structuralism. While framing his so-called "Hamiltonian derivatives" along the lines of previously available variational methods allowing to derive gravitational field equations from an action principle, Eddington assigned them a theoretical function of his own devising in The Mathematical Theory of Relativity (1923). I make clear that two stages should be marked out in Eddington's train of thought if the meaning of such variational derivatives is to be adequately assessed. As far as they were originally intended to embody the mind's collusion with nature by linking atomicity of matter with atomicity of action, variational derivatives were at first assigned a dual role requiring of them not only to express mind's craving for permanence but also to tune up mind's privileged pattern to "Nature's own idea". Whereas at a later stage, as affine field theory would provide a framework for world-building, such "Hamiltonian differentiation" would grow out of tune through gauge-invariance and, by disregarding how mathematical theory might precisely come into contact with actual world, would be turned into a mere heuristic device for structural knowledge.

    Extensive and rapid losses of sea ice in the Arctic have raised conservation concerns for the Pacific walrus (Odobenus rosmarus divergens), a large pinniped inhabiting arctic and subarctic continental shelf waters of the Chukchi and Bering seas. We developed a Bayesian network model to integrate potential effects of changing environmental conditions and anthropogenic stressors on the future status of the Pacific walrus population at four periods through the twenty-first century. The model framework allowed for inclusion of various sources and levels of knowledge, and representation of structural and parameter uncertainties. Walrus outcome probabilities through the century reflected a clear trend of worsening conditions for the subspecies. From the current observation period to the end of century, the greatest change in walrus outcome probabilities was a progressive decrease in the outcome state of robust and a concomitant increase in the outcome state of vulnerable. The probabilities of rare and extirpated states each progressively increased but remained level of 10% in 2004 to 22% by 2050 and 40% by 2095. The degree of uncertainty in walrus outcomes increased monotonically over future periods. In the model, sea ice habitat (particularly for summer/fall) and harvest levels had the greatest influence on future population outcomes. Other potential stressors had much smaller influences on walrus outcomes, mostly because of uncertainty in their future states and our current poor understanding of their mechanistic influence on walrus abundance.

    This study used magnetic resonance imaging to analyze causes and clinical courses of pediatric occipital lobe injury. Patients undergoing magnetic resonance imaging for suspected bilateral occipital lobe injury at our Neurodevelopmental Department between July 2007 and June 2011 were included. We evaluated magnetic resonance imaging characteristics, clinical courses, electroencephalogram monitoring, and Denver Development Screen Test scores. Twenty-one infants were examined. Of these, 10 had been born preterm. Thirteen patients demonstrated hypoglycemia. Perinatal period hypoglycemia comprised the most common cause (71.4%) of occipital brain injury. Visual abnormalities were evident in 18 patients. Seventeen (80.9%) patients manifested epilepsy. Infantile spasms were observed in 13 cases (76.5%). According to Denver Development Screen Test assessment, 17 patients demonstrated delayed motor development. Motor function and language improved in 10 patients after effective control of their seizures. Hypoglycemia constitutes the most common cause of occipital injury in infants. Visual impairment, startle episodes, infantile spasms, and motor developmental delay comprise the most common complications, whereas language function is usually spared.

    1992-01-01

    The Twenty-Second Department of Energy/Nuclear Regulatory Commission Nuclear Air Cleaning and Treatment Conference was held Aug. 24-27, 1992, in Denver, Colo. A total of 224 air-cleaning specialists attended the conference. The United States and 12 foreign countries were represented, and the specialists were affiliated with government agencies, educational institutions, and all aspects of the nuclear industry, including utilities, architect engineers, equipment suppliers, and consultants. Several major topics were discussed, similar to areas covered at previous conferences: chemical processing off-gas cleaning; particulate filler developments, including filter testing, performance, and response to physical stress,adsorber testing and performance, including laboratory and in-place testing; waste management; system operation; codes and standards; and advanced nuclear power plants. The conference continued to provide an effective forum for direct interchange of information of both a practical and theoretical nature. International participation and interest continues, as evidenced by over 40% of the papers being sponsored by foreign interests and almost 20% of the attendees being from outside the United States. The potential for new, safer nuclear plants of an advanced design was an optimistic note during the conference. Regulatory authorities are playing a major role in providing guidance in the development of safety goals and other technical criteria for these new installations

    2010-01-01

    To investigate the efficacy of '20 -tilt anteroposterior (A-P) radiography' in the assessment of lateral condylar fractures of the distal humerus. Eighteen children with lateral humeral condylar fractures were studied. Every child underwent conventional A-P and lateral radiography, and six children underwent multi-detector computed tomography (MDCT). For the investigation of 20 -tilt radiography, ten children with lateral humeral condylar fractures had conventional and 20 -tilt A-P and lateral radiography both preoperatively and postoperatively. Fragment dislocation was measured at the lateral and medial margins of the fracture on both the conventional A-P and 20 -tilt A-P radiographs. The lateral condylar fragment was triangular and was most prominent posteriorly. The fracture line was typically tilted approximately 20 to a reference line perpendicular to the long axis of the humerus in the lateral view. The extent of dislocation at the lateral and medial margins of the fracture site by 20 -tilt A-P radiography (9.3 ± 3.6 mm and 5.6 ± 2.5 mm) was significantly wider than that measured by the conventional method (6.8 ± 4.1 mm and 2.0 ± 1.5 mm), which may influence treatment. Twenty-degree-tilt A-P radiography may more precisely demonstrate fragment dislocation than standard radiographs and may influence patient treatment. (orig.)

  15. Twenty Years of National Minority Protection in the Republic of Croatia

    2011-12-01

    Full Text Available The paper contains a review of policies towards national minorities in the Republic of Croatia in the past twenty years, with reference to the perspective of minority rights implementation. The topic has been analysed in relation to two independent variables – the influence of external factors, i.e. the international community, and internal political processes that have had influence on the realisation of national minority rights. Today, as a country and society on the eve of accession to the European Union, along with a legislatively developed and institutionally branched model of the implementation of national minority rights, we can not claim to have established permanent protection of their rights. The degree of national minority integration in society is the only true indicator of policy success in relation to national minorities. The goal of this policy ought to be complete integration of national minorities into public, cultural, economic and political life, but accompanied by the preservation of their cultural and national identity. The Croatian model has been set up in such a way, but the manner in which it functions will depend on the political will to implement it, the willingness of national minority members to be active subjects of social and political life, as well as on civil society and Croatian society as a whole.

    Stephen Hawking's inaugural lecture as Lucasian Professor of Mathematics at Cambridge University in 1980 caused quite a stir. Its title - 'Is the end in sight for theoretical physics?' - raised the prospect of a unified 'theory of everything'. Hawking suggested that there was a good chance of resolving the remaining inconsistencies between the two big 'theories of something' - quantum mechanics and general relativity - before the turn of the century. My first impression on reading The New Physics for the Twenty-First Century, a collection of essays edited by science journalist Gordon Fraser, is that a theory of everything may still be attainable by the turn of the century. However, there is now 20 times more of everything in the universe than there was in the past century, 95% of which no-one has ever actually seen, or had even heard of until a few years ago - as summarized in articles by Wendy Freedman, Edward Kolb and Ronald Adler. Despite this, Michael Green describes amazing developments in string theory that could tie everything together, if one could just figure out which, if any, of the apparently infinite varieties of string theory applies to our world, and why.

Collections were made from the different biodiversity zones of India including Western Himalaya, Northeast Himalaya, Gangetic plain, Western Ghats, Semiarid Zone, and Central Highlands. Aseptic cultures were raised at the morphogenic level of callus, suspension, axillary shoot, multiple shoot, and rooted plants. Synseeds were also produced from highly proliferating shoot cultures of Bacopa monnieri, Glycyrrhiza glabra, Stevia rebaudiana, Valeriana wallichii, Gentiana kurroo, Lavandula officinalis, and Papaver somniferum. In vitro flowering was observed in Papaver somniferum, Psoralea corylifolia, and Ocimum sanctum shoots cultures. Out of 23 plants, 18 plants were successfully hardened under glasshouse conditions.

  18. Diverging seasonal extremes for ocean acidification during the twenty-first century

    2018-01-01

    How ocean acidification will affect marine organisms depends on changes in both the long-term mean and the short-term temporal variability of carbonate chemistry1-8. Although the decadal-to-centennial response to atmospheric CO2 and climate change is constrained by observations and models1, 9, little is known about corresponding changes in seasonality10-12, particularly for pH. Here we assess the latter by analysing nine earth system models (ESMs) forced with a business-as-usual emissions scenario13. During the twenty-first century, the seasonal cycle of surface-ocean pH was attenuated by 16 ± 7%, on average, whereas that for hydrogen ion concentration [H+] was amplified by 81 ± 16%. Simultaneously, the seasonal amplitude of the aragonite saturation state (Ωarag) was attenuated except in the subtropics, where it was amplified. These contrasting changes derive from regionally varying sensitivities of these variables to atmospheric CO2 and climate change and to diverging trends in seasonal extremes in the primary controlling variables (temperature, dissolved inorganic carbon and alkalinity). Projected seasonality changes will tend to exacerbate the impacts of increasing [H+] on marine organisms during the summer and ameliorate the impacts during the winter, although the opposite holds in the high latitudes. Similarly, over most of the ocean, impacts from declining Ωarag are likely to be intensified during the summer and dampened during the winter.

    Full Text Available This study has been narrowed down to reveal a paradox. Here the vanguard of culture and civilization - which is regarded as young people of the twenty-first century – is embroiled in a discourse of exclusion: economic, political and cultural life. In secondary school programs and high schools we do not find specific references and studies, primarily based on the needs of students, about the theory of popular culture and cultural education in the area of pop culture. The paradox of exclusion of mainstream culture from educational discourse is schizophrenic. The political exclusion of young people of the XXI century I consider all the disparaging scientific discourse, which skips the actual media and communication competence of young people. Prosumers, cognitarchy, digital natives, C-generation – they are for the modern economy “Silicon Valley” - their market power to exclude is already unstoppable. In other areas it remains to be considered whether excluding young people from the cultural discourse will not deprive our future teachers and translators of the next civilization revolution of social reality...

    During the war or shortly thereafter, the most common manifestation of combat induced psychopathology is combat stress reaction (CSR). The long-term consequences of CSR have so far received little scientific attention. The aim of this study was to examine whether CSR is a marker for long-term PTSD and other psychiatric comorbidities. Two groups of veterans from the 1982 Lebanon war were assessed 20 years after the war: one comprised 286 CSR casualties and the other comprised 218 matched non-CSR soldiers. Participants were assessed for PTSD, psychiatric symptomatology, social functioning, physical health, and postwar life events. Twenty years after the war, veterans with antecedent CSR reported more PTSD, psychiatric symptomatology and distress, social dysfunction, and health problems than did non-CSR veterans. We conclude that CSR should be seen as a marker for long-term psychiatric distress and impairment. In addition, the implications of combat-related trauma are broad and varied, and go beyond the narrow scope of PTSD.

    Human history is also the record of our fascination with the sky, and to look upwards is to follow in the steps of such greats as Galileo and Newton. What they and others once saw in the heavens for the first time, amateur astronomers can discover anew using this guide to twenty-five of the greatest journeys through space.   Starting with our most visible companion the Moon, each chapter offers a step-by-step walk-through of famous astronomical observations from the history of science. Beginning with the easiest targets, sometimes even accessible with the naked eye, the challenges become progressively more difficult. Beginner astronomers and more experienced hobbyists alike can reacquaint themselves with the wonders of our fellow planets and even reach far beyond our own solar system to touch on such incredible phenomena as the birth of new stars in nebula systems and the deceptive nothingness of black holes.

    Through the combination of manual retrieval and computerized retrieval, medical records of acupuncture-moxibustion in The Twenty-Four Histories were collected. Acupuncture cases from the Spring and Autumn Period (770-476 B.C.) to the end of the Ming Dynasty (1368-1644)were retrieved. From the medical records of acupuncture-moxibustion in Chinese official history books, it can be found that systematic diseases or emergent and severe diseases were already treated by physicians with the combination of acupuncture and medicine as early as in the Spring and Autumn Period as well as the Warring States Period(475-221 B.C.). CANG Gong, a famous physician of the Western Han Dynasty (206 B. C.-A. D. 24), cured diseases by selecting points along the running courses of meridians where the illness inhabited, which indicates that the theory of meridians and collaterals was served as a guide for clinical practice as early as in the Western Han Dynasty. Blood letting therapy, which has surprising effect, was often adopted by physicians of various historical periods to treat diseases. And treatment of diseases with single point was approved to be easy and effective.

  3. Phenotypic Responses of Twenty Diverse Proso Millet (Panicum miliaceum L. Accessions to Irrigation

    Full Text Available To date, little research has been conducted on the phenotypic responses of proso millet to drought and deficit irrigation treatments in the dryland wheat-based cropping systems of the Palouse bioregion of the U.S. The objectives of this study were to evaluate critical agronomic traits of proso millet, including emergence, plant height, days to heading, days to maturity, and grain yield, with and without supplemental irrigation. Twenty diverse proso millet accessions, originating from Bulgaria, Czechoslovakia, Morocco, the former Soviet Union, Turkey, and the United States, were grown in irrigated and non-irrigated treatments under organic conditions in Pullman, WA, from 2012 to 2014. Irrigation was shown to significantly improve emergence and increase plant height at stem extension and to hasten ripening of all the varieties, whereas heading date was not affected by irrigation in two of the three years tested. Irrigation resulted in higher mean seed yield across all varieties, with ‘GR 665’ and ‘Earlybird’ performing best under irrigation. Seed yield was highest in ‘GR 658’ and ‘Minsum’ in the non-irrigated treatment, suggesting the importance of identification and utilization of varieties adapted to low rainfall conditions. The highest yielding varieties in irrigated systems are unlikely be the highest yielding in dryland systems. Our results suggest that millet has potential as a regionally novel crop for inclusion in traditional dryland cropping rotations in the Palouse ecosystem, thereby contributing to increased cropping system diversity.

    2012-12-01

    The twenty-first century presents a major challenge for civil engineering. The magnitude and future importance of some of the problems perceived by society are directly related to the field of the civil engineer, implying an inescapable burden of responsibility for a group whose technical soundness, rational approach and efficiency is highly valued and respected by the citizen. However, the substantial changes in society and in the way it perceives the problems that it considers important call for a thorough review of our structures, both professional and educational; so that our profession, with its undeniable historical prestige, may modernize certain approaches and attitudes in order to continue to be a reliable instrument in the service of society, giving priority from an ethical standpoint to its actions in pursuit of "the public good". It possesses important tools to facilitate this work (new technologies, the development of communications, the transmission of scientific thought.···); but there is nevertheless a need for deep reflection on the very essence of civil engineering: what we want it to be in the future, and the ability and willingness to take the lead at a time when society needs disinterested messages, technically supported, reasonably presented and dispassionately transmitted.

    There are many opportunities and challenges for conducting occupational epidemiologic studies today. In this paper, we summarize the discussion of a symposium held at the Epidemiology in Occupational Health (EPICOH) conference, Chicago 2014, on challenges for occupational epidemiology in the twenty-first century. The increasing number of publications and attendance at our conferences suggests that worldwide interest in occupational epidemiology has been growing. There are clearly abundant opportunities for new research in occupational epidemiology. Areas ripe for further work include developing improved methods for exposure assessment, statistical analysis, studying migrant workers and other vulnerable populations, the use of biomarkers, and new hazards. Several major challenges are also discussed such as the rapidly changing nature and location of work, lack of funding, and political/legal conflicts. As long as work exists there will be occupational diseases that demand our attention, and a need for epidemiologic studies designed to characterize these risks and to support the development of preventive strategies. Despite the challenges and given the important past contribution in this field, we are optimistic about the importance and continued vitality of the research field of occupational epidemiology.

    Full Text Available Hyphema (hemorrhage within the anterior chamber of the eye can be caused by several mechanisms and can easily be detected in routine ophthalmic or necroscopic examination as discolored red eye(s. The purpose of this study is to report the cause of hyphema diagnosed as a postmortem finding in dogs and cats. Twenty cases, 14 dogs and six cats of several ages and breeds and of both sexes were included in the study. Hyphema presented as a unilateral (14 cases out of 20 or bilateral (6/20 disorder in dogs and cats and extension of hemorrhage varied from minimal to diffuse. Hyphema was secondary to systemic disease (15/20 or occurred as a primary ocular lesion (5/20 in four dogs and one cat. Primary hyphema was always unilateral. In four of these cases, the cause of hyphema was trauma and remaining case was caused by phacoclastic uveitis in a dog with bilateral hypermature cataract. Various causes of bleeding disorders were found related to secondary hyphema: in decreasing order of frequency, they included vasculitis (8/15, systemic hypertension (5/15, and acquired coagulopathies (2/15. Vasculitis due to feline infectious peritonitis accounted for half of the cases (n=3 of systemic hyphema in cats. The various pathological aspects and pathogenesis of hyphema in dogs and cats are described and discussed.

    Twenty-five years ago, in the night of July 27 to 28, 1978, the AKR-1 nuclear training reactor of the Dresden Technical University went critical for the first time and was commissioned. On the occasion of this anniversary, a colloquy was arranged with representatives from science, politics and industry, at which the reactor's history, the excellent achievements in research and training with the reactor, and the status and perspectives of this research facility were described. The AKR-1 had been built within the framework of the Nuclear Development Program of the then German Democratic Republic (GDR). The Nuclear Power Scientific Division of the Dresden Technical University had been entrusted with the responsibility, among other things, to train university personnel for the GDR Nuclear Power Program. The review by an expert group in 1996 of this plant had resulted in a recommendation in favor of long-term plant operation. A nuclear licensing procedure to this effect was initiated, and the necessary technical backfitting measures were implemented. The AKR-1 plant now equally serves for the specialized training of students and for research. (orig.) [de

  9. An empirical examination of consumer effects across twenty degrees of latitude.

    The strength and importance of consumer effects are predicted to increase toward low latitudes, but this hypothesis has rarely been tested using a spatially consistent methodology. In a consumer-exclusion experiment spanning twenty degrees of latitude along the east Australian coast, the magnitude of consumer effects on sub-tidal sessile assemblage composition was not greater at low than high latitudes. Across caged and control assemblages, Shannon's diversity, Pielou's evenness, and richness of functional groups decreased with increasing latitude, but the magnitude of consumer effects on these metrics did not display consistent latitudinal gradients. Instead, latitudinal gradients in consumer effects were apparent for individual functional groups. Solitary ascidians displayed the pattern consistent with predictions of greater direct effects of predators at low than high latitude. As consumers reduced the biomass of this and other competitive dominants, groups less prone to predation (e.g., hydroids, various groups of bryozoans) were able to take advantage of freed space in the presence of consumers and show increased abundances there. This large-scale empirical study demonstrates the complexity of species interactions, and the failure of assemblage-level metrics to adequately capture consumer effects over large spatial gradients. © 2017 by the Ecological Society of America.

    The twenty-first in a series of nuclear accident dosimetry (NAD) intercomparison (NAD) studies was conducted at the Oak Ridge National Laboratory's Dosimetry Applications Research Facility during August 6-10, 1984. The Health Physics Research Reactor operated in the pulse mode was used to simulate three criticality accidents with different radiation fields. Participants from five organizations measured neutron doses between 0.53 and 4.36 Gy and gamma doses between 0.19 and 1.01 Gy at area monitoring stations and on phantoms. About 75% of all neutron dose estimates based on foil activation, hair activation, simulated blood sodium activation, and thermoluminescent methods were within +-25% of reference values. Approximately 86% of all gamma results measured using thermoluminescent (TLD-700 or CaSO 4 ) systems were within +-20% of reference doses which represents a significant improvement over previous studies. Improvements observed in the ability of intercomparison participants to estimate neutron and gamma doses under criticality accident conditions can be partly attributed to experience in previous NAD studies which have provided practical tests of dosimetry systems, enabled participants to improve evaluation methods, and standardized dose reporting conventions. 16 refs., 15 tabs

    Mueller, Thorsten (ed.)

    2012-07-01

    The present volume was compiled as part of a project funded by the German Federal Ministry for Environment, Nature Conservation and Reactor Safety, one event under which was the seventh Wuerzburg conference on environmental energy law with the title ''Twenty Years of Renewable Energy Law'' which took place on 13/14 October 2010. It comprises 36 contributions which, from different scientific perspectives, take stock of the significance of renewable energies for climate protection and the energy supply, examine the developments of the past 20 years and draw conclusions for the future use of renewable energy. The authors are scientists from the areas of climate research, economics, political science, engineering, environmental psychology and jurisprudence who have dedicated their work to issues that directly or indirectly relate to the expansion of renewable energies. Together they have created an overall picture of renewable energies with its many different aspects and related topics, a picture that necessarily cannot be complete but which nevertheless provides many rich insights. The great majority of articles were written around the turn of the year to 2011, just after the granting of lifetime extension for German nuclear power plants. They thus only take sparse account of the diverse and for some part far-reaching changes in German energy policy that came about after the reactor disaster in Fukushima.

  12. Industries processing naturally occurring radioactive materials: twenty years of emission data in the Netherlands

    Tanzi, C.P.

    2008-01-01

    This paper provides a review of the dose assessment of discharges to air of two industries processing NORM (Naturally Occurring Radioactive Materials) in the Netherlands. An industrial plant producing elemental phosphorus (thermal process, unique within Europe) reports since 1987 its emission data to the Dutch Ministry of the Environment (VROM: Ministry of Housing, Spatial Planning and the Environment). This plant accounts for the highest release of Po-210 to air in the Netherlands, with a yearly average of approximately 500 GBq. Other significant NORM discharges to air arise from an industrial plant with blast-furnaces for steel production. Yearly discharges fall under permit, and are reported, since 1993. RIVM, the National Institute for Public Health and the Environment, is tasked by the Ministry to assess the dose to the general public arising from these discharges to air. Air transport modelling is used to determine both air concentration (for inhalation exposure) and deposition rate of the radionuclides. A (conservative) committed ingestion dose is determined by modelling the uptake of radionuclides from contaminated farmland, and assuming a food basket to be fairly representative for the population of the Netherlands. Discharges to water in the Netherlands have decreased in the past twenty years, due both to the closure of two phosphoric acid plants a decade ago and the improved treatment of waste fluids by other NORM industries. The collective dose assessed from discharges to air since 1987 is presented here. (author)

    Full Text Available Grapes are rich in phytochemicals with many proven health benefits. Phenolic profiles, antioxidant and antiproliferative activities of twenty-four selected Vitis vinifera grape cultivars were investigated in this study. Large ranges of variation were found in these cultivars for the contents of total phenolics (95.3 to 686.5 mg/100 g and flavonoids (94.7 to 1055 mg/100 g and antioxidant activities (oxygen radical absorbance capacity 378.7 to 3386.0 mg of Trolox equivalents/100 g and peroxylradical scavenging capacity14.2 to 557 mg of vitamin C equivalents/100 g, cellular antioxidant activities (3.9 to 139.9 µmol of quercetin equivalents/100 g without PBS wash and 1.4 to 95.8 µmol of quercetin equivalents /100 g with PBS wash and antiproliferative activities (25 to 82% at the concentrations of 100 mg/mL extracts.The total antioxidant activities were significantly correlated with the total phenolics and flavonoids. However, no significant correlations were found between antiproliferative activities and total phenolics or total flavonoids content. Wine grapes and color grapes showed much higher levels of phytochemicals and antioxidant activities than table grapes and green/yellow grapes. Several germplasm accessions with much high contents of phenolics and flavonoids, and total antioxidant activity were identified. These germplasm can be valuable sources of genes for breeding grape cultivars with better nutritional qualities of wine and table grapes in the future.

    During the spring and summer months of 1987, the Aero Propulsion Laboratory of the Air Force Wright Aeronautical Laboratories, Wright-Patterson AFB, Ohio in cooperation with the Air Force Space Technology Center at Kirtland AFB, New Mexico, undertook an initiative to develop a Strategic Plan for Space Power Technology Development. The initiative was called SPT21, Space Power Technology for the Twenty-First Century. The planning process involved the participation of other Government organizations (U.S. Army, Navy, DOE and NASA) along with major aerospace companies and universities. Following an SPT21 kickoff meeting on 28 May 1987, detailed strategic planning was accomplished through seven (7) Space Power Technology Discipline Workshops commencing in June 1987 and concluding in August 1987. Technology Discipline Workshops were conducted in the following areas: (1) Solar Thermal Dynamic Power Systems (2) Solar Photovoltaic Cells and Arrays (3) Thermal Management Technology (4) Energy Storage Technology (5) Nuclear Power Systems Technology (6) Power Conditioning, Distribution and Control and (7) Systems Technology/Advanced Concepts. This technical paper summarizes the planning process and describes the salient findings and conclusions of the workshops

  15. Twenty years of student sexual behavior: subcultural adaptations to a changing health environment.

    Science.gov (United States)

    Netting, Nancy S; Burnett, Matthew L

    2004-01-01

    This twenty-year study analyzes changes in sexual behavior among students at Okanagan University College in British Columbia, Canada. Surveys conducted in 1980, 1990, and 2000 reveal a steady increase in safer sexual practices. Most students now question potential partners about their past, use condoms with a new sexual partner, and maintain fairly long-term monogamous relationships. Three sexual subcultures continue to coexist in fairly stable proportions: celibacy (about 30%), monogamy (about 60%), and free experimentation (about 10%). Each subculture has created its own response to the danger of HIV/AIDS: celibates exaggerate the danger they face, monogamists rely on love and fidelity for protection, and free experimenters have increased their use of condoms. While romantic feelings lead many monogamous couples to abandon condoms without objective HIV/AIDS knowledge, free experimenters still face the highest risk. Although they now use condoms more than half the time, their lifestyle, which involves multiple partners, risky sexual acts, and frequent drug and/or alcohol use, clearly remains dangerous. The persistence of distinct subcultures has implications for health education programs, which would be most effective if based on key values held by specific target groups.

    The 1988 Yellowstone fires were among the first in what has proven to be an upsurge in large severe fires in the western USA during the past 20 years. At the time of the fires, little was known about the impacts of such a large severe disturbance because scientists had had few previous opportunities to study such an event. Ecologists predicted short- and long-term effects of the 1988 fires on vegetation, biogeochemistry, primary productivity, wildlife, and aquatic ecosystems based on scientific understanding of the time. Twenty-plus years of subsequent study allow these early predictions to be evaluated. Most of the original predictions were at least partially supported, but some predictions were refuted, others nuanced, and a few postfire phenomena were entirely unexpected. Post-1988 Yellowstone studies catalyzed advances in ecology focused on the importance of spatial and temporal heterogeneity, contingent influences, and multiple interacting drivers. Post-1988 research in Yellowstone also has changed public perceptions of fire as an ecological process and attitudes towards fire management. Looking ahead to projected climate change and more frequent large fires, the well-documented ecological responses to the 1988 Yellowstone fires provide a foundation for detecting and evaluating potential changes in fire regimes of temperate mountainous regions. ?? 2011 Springer Science+Business Media, LLC.

    ASBTRACT Toxicity of twenty-two essential oils to three bacterial pathogens in different horticultural systems: Xanthomonas campestris pv. phaseoli (causing blight of bean), Clavibacter michiganensis subsp. michiganensis (bacterial wilt and canker of tomato), and Pseudomonas tolaasii (causal agent of bacterial brown blotch on cultivated mushrooms) was tested. Control of bacterial diseases is very difficult due to antibiotic resistance and ineffectiveness of chemical products, to that essential oils offer a promising alternative. Minimal inhibitory and bactericidal concentrations are determined by applying a single drop of oil onto the inner side of each plate cover in macrodilution assays. Among all tested substances, the strongest and broadest activity was shown by the oils of wintergreen (Gaultheria procumbens), oregano (Origanum vulgare), and lemongrass (Cymbopogon flexuosus. Carvacrol (64.0-75.8%) was the dominant component of oregano oils, while geranial (40.7%) and neral (26.7%) were the major constituents of lemongrass oil. Xanthomonas campestris pv. phaseoli was the most sensitive to plant essential oils, being susceptible to 19 oils, while 11 oils were bactericidal to the pathogen. Sixteen oils inhibited the growth of Clavibacter michiganensis subsp. michiganensis and seven oils showed bactericidal effects to the pathogen. The least sensitive species was Pseudomonas tolaasii as five oils inhibited bacterial growth and two oils were bactericidal. Wintergreen, oregano, and lemongrass oils should be formulated as potential biochemical bactericides against different horticultural pathogens.

    Full Text Available Salman Rushdie’s memoirs, essays and novels contribute to the appreciation of the contradictions in his outlook on life. His experiences in his family enable Rushdie to make efforts for objective and tolerant judgement of British lifestyle and culture. However, his isolation from the society in Britain despite his struggle for adaptation to British cultural values cause contradictions in his cultural identity. While Rushdie expresses his allegiance to India and its culture in The Ground Beneath Her Feet (1999, he reflects his alienation from his homeland in this novel as well. Similarly, in his Imaginary Homelands (1981-1991 whereas Rushdie questions the injustice and inequality caused by imperialism in The New Empire within Britain (1982, he justifies the colonialist discourse in Kipling (1990. He elaborates on the contradictions in his outlook on life in terms of his cultural ambivalence in his fictions such as Midnight’s Children (1981 and Shame (1983. However, in his latest novel, Two Years, Eight Months and Twenty-Eight Nights (2015, Rushdie reflects his cultural identity conflict in terms of rationalism-mysticism dichotomy. With the use of allegory as well as the lack of linearity in time and space, Rushdie justifies his cultural ambivalence in relation to the dynamism of contemporary world. Thus, Rushdie’s latest novel invites reading for its representation of the oppositions in his approach to life.

    OBJECTIVE: The preservation of biological samples at a low temperature is important for later biochemical and/or histological analyses. However, the molecular viability of thawed samples has not been studied sufficiently in depth. The present study was undertaken to evaluate the viability of intact tissues, tissue homogenates, and isolated total RNA after defrosting for more than twenty-four hours. METHODS: The molecular viability of the thawed samples (n = 82) was assessed using the A260/A280 ratio, the RNA concentration, the RNA integrity, the level of intact mRNA determined by reverse transcriptase polymerase chain reaction, the protein level determined by Western blotting, and an examination of the histological structure. RESULTS: The integrity of the total RNA was not preserved in the thawed intact tissue, but the RNA integrity and level of mRNA were perfectly preserved in isolated defrosted samples of total RNA. Additionally, the level of β-actin protein was preserved in both thawed intact tissue and homogenates. CONCLUSION: Isolated total RNA does not undergo degradation due to thawing for at least 24 hours, and it is recommended to isolate the total RNA as soon as possible after tissue collection. Moreover, the protein level is preserved in defrosted tissues. PMID:22473407

    Full Text Available The Baltic Sea, one of the world’s largest semi-enclosed seas, which, with its very low salinity and quasi-isolation from the big oceans cannot decide whether it is a sea or a large lake. This geologically-unique environment supports an even more surprising and delicate marine ecosystem, where a complex community of fishes, marine mammals and important microscopic organisms creates a magical mosaic of life. Humans have enjoyed the abundance of life in the Baltic Sea for thousands of years, and major Scandinavian and Baltic cities have oriented themselves towards this geo-ecosystem in order to develop and seek ecological, economical and cultural inspiration and wealth. The ‘Mosaic of Life’ workshop aimed at going beyond the obvious in examining the meaning of the Baltic Sea by gathering together a selection of young, creative minds from different backgrounds ranging from the arts and economics to geology and life sciences. This intensive workshop was designed as a unique training opportunity to develop essential twenty-first century skills – to introduce and develop creative, critical and interdisciplinary thinking and collaborative teamwork, as well as to foster a visual and scientific literacy, using project-based learning and hands-on activities. Our final goal has been to be inspired by the resulting connections, differences and unifying concepts, creating innovative, interdisciplinary projects which would look further than the sea – further than the eye can see and further into the future.

    Directory of Open Access Journals (Sweden)

    Konstantinović-Vilić Slobodanka

    2014-01-01

    Full Text Available The subject matter of this paper is an analysis of stereotypical social reactions to women’s alcoholism in the micro and macro social and cultural environment. The social stigma and blame that female alcohol abusers are exposed to have become part of deeply rooted gender-related labels. In a broader social context, they lead to discrimination and social exclusion. In the contemporary society, female alcoholism is turning into a growing social and health problem and because of that it is essential to make the social environment more sensitive to the issue of female alcoholism in order to eliminate the causes of female alcoholism and fully support women’s medical treatment,. It would have a preventive effect in suppressing female alcoholism and it would significantly reduce victimization of women who are, in such circumstances, much more vulnerable and exposed to physical and sexual violence. The aim of this paper is to point out to the basic phenomenological and etiological feature of female alcoholism, prejudices and stereotypical attitudes they are exposed to, social and cultural implications of female alcoholism, which is perceived as a predisposition for women’s victimization and exposure to violence, so as to promote a different social approach to female alcoholism and advocate for instituting social and educational policy based on the concept of gender equality and support of social control measures.

    Weckerly, Floyd W.; Ricca, Mark A.

    2014-01-01

    Female caribou (Rangifer tarandus) are highly gregarious, yet there has been little study of the behavioral mechanisms that foster coexistence. Quantifying patterns of aggression between male and female, particularly in the only cervid taxa where both sexes grow antlers, should provide insight into these mechanisms. We asked if patterns of aggression by male and female caribou followed the pattern typically noted in other polygynous cervids, in which males display higher frequencies and intensity of aggression. From June to August in 2011 and 2012, we measured the frequency and intensity of aggression across a range of group sizes through focal animal sampling of 170 caribou (64 males and 106 females) on Adak Island in the Aleutian Archipelago, Alaska. Males in same-sex and mixed-sex groups and females in mixed-sex groups had higher frequencies of aggression than females in same-sex groups. Group size did not influence frequency of aggression. Males displayed more intense aggression than females. Frequent aggression in mixed-sex groups probably reflects lower tolerance of males for animals in close proximity. Female caribou were less aggressive and more gregarious than males, as in other polygynous cervid species.

    Recent rodent studies have demonstrated that parental cocaine exposure can influence offspring behavior, supporting the idea that environmental insults can impact subsequent generations. However, studies on the effects of paternal cocaine exposure are limited and multiple inconsistencies exist. In the current study, we behaviorally characterize the effects of paternal cocaine exposure in a C57BL/6J intergenerational mouse model. Male sires were administered cocaine hydrochloride (20mg/kg) or saline (0.01mL/g) once a day for 75days, and bred with drug naïve females twenty-four hours after the final injection. Offspring, separated by sex, were tested in a battery of behaviors. We found that paternal cocaine exposure altered sensitivity to the rewarding and stimulant effects of psychostimulants and natural reward (sucrose) in female offspring; female cocaine-sired offspring showed blunted cocaine preference using cocaine conditioned place preference (CPP) at a low dose (5mg/kg), but displayed similar preference at a higher dose (10mg/kg) compared to saline-sired controls. Additionally, cocaine-sired female offspring exhibited higher psychomotor sensitivity to cocaine (10mg/kg) and amphetamine (2mg/kg) and consumed more sucrose. Cocaine-sired males exhibited increased psychomotor effects of cocaine and amphetamine. Male offspring also displayed an anxiety-like phenotype. No effect of paternal cocaine exposure was observed on depressive-like, learning and memory or social behavior in male or female offspring. Collectively, our findings show that paternal, chronic cocaine exposure induces intergenerational behavioral effects in male and female offspring with greatest impact on sensitivity to psychostimulants and sucrose in females.

    Female professional contributions in nuclear science and technology are no longer a novelty. Names such as Marie Curie, Chen Shiung Wu and Rosalyn Yalow are evidence of the incessant, worldwide efforts of women to take part in fields largely reserved for men. Although society has witnessed high level female achievements as early as in the 1800s, female scientists and technicians still face a long journey ahead in empowering themselves into full and equal participation in these areas. Today, the Laboratory of Poços de Caldas of the Brazilian Commission for Nuclear Energy (CNEN/LAPOC) experiences a process of women empowerment at all levels of the institution. At the Technical Section, two of the seven research departments are headed by female researchers who play essential roles in the institution’s quest for excellence. Today, their work include coordination of a major environmental research project involving most researchers at LAPOC, successful participations on international intercomparisons of radiometric analysis and development of new methodologies in nuclear field applications. At the administrative level, female collaborators lead the Administration Section, improving several aspects of internal management, promoting further interaction at the workplace and strengthening cooperation among all departments. Regarding the capacitation level, the Commission has a long tradition of welcoming students and junior researchers through institutional programmes of training and collaboration in several projects. Today CNEN/LAPOC works with twenty scholarship grantees — half of which are women. Not only the Laboratory has reached equality in participation, but unarguably the female participants have demonstrated the most remarkable achievements among the group, attested by their continuous academic pursuit through Master’s and Doctoral degrees, full collaboration in scientific publishing and attendance in training programmes at international level.

    The rapid transition of female Australian football players from amateur to semi-elite competitions has the potential for athletes to be underprepared for match-play. To gain an understanding the match demands of female football, the aims of this study were three-fold: (1) to highlight the physical qualities that discriminate selected and non-selected female Australian Football players, (2) to investigate activity profiles of female Australian Football players, and (3) to gain an understanding of the influence of physical qualities on running performance in female Australian Football match-play. Twenty-two female Australian football (AF) state academy players (mean ± SD age, 23.2 ± 4.5 years) and 27 non-selected players (mean ± SD age, 23.4 ± 4.9 years) participated in this study. The Yo-Yo Intermittent Recovery Test (Level 1), countermovement jump and 30m sprint tests were completed prior to the competitive season. During 14 matches, players wore global positioning system (GPS) units to describe the running demands of female AF match-play. Selected players were faster over 30 metres (ES=0.57; p=0.04) and covered greater distances on the Yo-Yo IR1 test (ES=1.09; pfemale AF players were faster and had greater intermittent running ability than players not selected to a State academy program. An emphasis should be placed on the development of physical fitness in this playing group to ensure optimal preparation for the national competition.

    2006-01-01

    Full Text Available Abstract Background The effect of Total Mesorectal Excision (TME on sexual function in the male is well documented. However, there is little literature in female patients. The aim of this study was to review the pelvic autonomic nervous anatomy in the female and to perform a retrospective audit of urinary and sexual function in women following surgery for rectal cancer where TME had been performed. Urogenital dysfunction was assessed through interview and questionnaire. Method Twenty-three questionnaires, eighteen returned, were sent to women with a mean age 65.5 yrs (range 34–86. All had undergone total mesorectal excision for rectal cancer between 1998–2001. Mean follow-up was 18.8 months (range 3–35. Results Preoperatively 5/18 (28% were sexually active, 3/18 (17% of patients described urinary frequency and nocturia and 7/18 (39% described symptoms of stress incontinence prior to surgery. Postoperatively all sexually active patients remained active although all described some discomfort with penetration. Two of the patients sexually active described reduced libido secondary to the stoma. Postoperative urinary symptoms developed with 59% reporting the development of nocturia, 18% developed stress incontinence and one patient required a permanent catheter. Of those with symptoms, 80% persisted longer than three months from surgery. Symptoms were predominant in those patients with low rectal cancers, particularly those undergoing abdomino-perineal excision and in those who had previously undergone abdominal hysterectomy. Conclusion The treatment of rectal cancer involves surgery to the pelvic floor. Despite nerve preservation this is associated with the development of worsening nocturia and stress incontinence. This is most marked in those patients who had previously undergone a hysterectomy. Further studies are warranted to assess the interaction with previous gynaecological surgery.

    This report describes the first antenatal diagnosis of an XXX female. Over 150 postnatal cases of XXX females have been described. There is no specific phenotype associated with the sex chromosome abnormality and most such persons are fertile. The frequency of XXX females in mental institutions is 3.9 per 1,000 female subjects whereas the frequency in consecutive newborn infants is 1.1 per 1,000 newborns. Chi-square analysis shows this difference cannot be due to chance. On the other hand, data from consecutive newborn studies suggest that intellectual development in XXX newborns is within normal range. Available evidence favors normal development in XXX female infants although the risk for developmental disabilities may be higher for the XXX than for the XX infant. ImagesFigure 1. PMID:1154778

    State fish and wildlife agencies are particularly interested in attracting female participation because of the potential to offset declining participation in hunting. Understanding female hunters’ motivations will be critical for designing effective recruitment and retention programs for women hunters. Although female participation in hunting is increasing, males still outnumber females by about tenfold. Gender differences in deer hunters were explored by comparing ratings of eight motivations (social, nature, excitement, meat, challenge, trophy, extra hunting opportunity, and solitude). Hunter types were defined by hunters’ selection of the most important motivation for why they like Black Hills deer hunting. Overall, females and males were relatively similar in their ratings of the eight motivations, and we found 85% gender similarity in the selection of the most important motivation. Women were slightly more motivated by the food aspect of the hunt while men placed slightly more value on the hunt as a sporting activity.

    Full Text Available There are many factors related to female entering the labor market. For example, household income, household expenditure, education and status of the head of the household (male/ female. The degree of correlation between each variable and female labor force participation rate varies throughout the country. This study focused on the factors due to which women enter in labor market. Tobit model is used for this analysis. It is concluded that education and household expenditures have positive but insignificant impact on the female LF, whereas household income and head of the household has negative impact on FLF. It is suggested that in order to improve the working condition of female labor force government should take necessary action, for example women education etc.

    Gender representation in Islamic bioethics research in the twenty-first century has not been studied. To study temporal trends in representation of female subjects in Islamic bioethics research, PubMed-listed publications on Islamic bioethics from years 2000 to 2014 were reviewed for gender participation in human subjects' research. There were temporal trends of increasing publications of Islamic bioethics-related human subjects' research (64 papers over 15 years; R 2  = 0.72; p < 0.0004). Female subjects were well represented with a trend toward increasing participation. This was true for women from Muslim-majority countries even in non-gender-focused studies over the past 15 years.

    As twenty-first century skills become a greater focus in K-12 education, an infusion of technology that meets the needs of today's students is paramount. This study looks at the design and creation of a Multiplayer Educational Gaming Application (MEGA) for high school biology students. The quasi-experimental, qualitative design assessed the twenty-first century skills of digital age literacy, inventive thinking, high productivity, and effective communication techniques of the students exposed to a MEGA. Three factors, as they pertained to these skills, emerged from classroom observations. Interaction with the teacher, discussion with peers, and engagement/time-on-task while playing the MEGA suggested that students playing an educational video game exhibited all of the projected twenty-first century skills while being engrossed in the embedded science content.

    Epidemiological studies have shown the adverse neuro-behavioral health effects of lead exposure among children, in particular. However, there is lack evidence in this regard from developing countries. The main aim of this study was to assess the association between blood lead levels (BLLs) during early adolescence and violent behavior in late adolescence. Our study sample from the Birth to Twenty Plus cohort in Soweto-Johannesburg, South Africa included 1332 study participants (684 females). BLLs were measured using blood samples collected at age 13years. Violent behavior was evaluated using data collected at ages 15 to 16years using the Youth Self Report questionnaire. First, bivariate analysis was used to examine data for an association between lead exposure in early adolescence and violent behavior items during late adolescence. Principal Component Analysis (PCA) was used for dimensionality reduction and six violent behavior components were derived. Data were further analyzed for an association between BLLs at age 13years and violent behavior using PCA derived components; to determine the specific type(s) of violent behavior associated with lead exposure. Median whole BLLs were 5.6μg/dL (plead exposure (plead exposure. They highlight the urgent need for preventive measures against lead exposure among children in low or middle income countries such as South Africa. Copyright © 2017 Elsevier Ltd.

    To verify the effects of plyometric training on lower limb kinematics, eccentric hip and knee torques, and functional performance. Cohort study. Research laboratory. Thirty-six females were divided into a training group (TG; n = 18) that carried out the plyometric training for 8 weeks, and a control group (CG; n = 18) that carried out no physical training. Twenty-four plyometric training sessions during approximately 8 weeks with 3 sessions per week on alternate days. Lower limb kinematics (maximum excursion of hip adduction, hip medial rotation, and knee abduction during the single leg squat), eccentric hip (abductor, adductor, medial, and lateral rotator) isokinetic peak torques and knee (flexor and extensor) isokinetic peak torques, and functional performance (triple hop test and the 6-m timed hop test). After 8 weeks, only the TG significantly reduced the values for the maximum excursion of knee abduction (P = 0.01) and hip adduction (P Plyometric training alters lower limb kinematics and increases eccentric hip torque and functional performance, suggesting the incorporation of these exercises in preventive programs for ACL injuries.

    Training load (TL) and recovery should be in optimal balance to obtain maximal performance gains. We aimed to study sleep as a recovery technique and its relationship with TL and performance in elite athletes. Twenty-six elite female artistic gymnasts were divided into an under 13 (n = 6), an under 14 (n = 6), a junior (n = 7; 14-15y) and a senior (=World Championship (WC) competitors, n = 7; ≥16y) category. Sleep, through sleep logs, and training parameters, using the session Rate of Perceived Exertion (sRPE) scale, were monitored to calculate total sleep time (TST), sleep efficiency (SE), TL, monotony and strain. Performance of WC competitors was evaluated through coach and WC qualification ranking. For the entire group, TST (effect sizes (ES) = -1.12, confidence intervals (CI) = -60:-47, P performance. Optimizing sleep and TL may therefore represent strategies to enhance performance.

    Our understanding of who is beautiful seems to be innate but has been argued to conform to mathematical principles and proportions. One aspect of beauty is facial shape that is gender specific. In women, an oval facial shape is considered attractive. To study the facial shape of beautiful actors, pageant title winners, and performers across ethnicities and in different time periods and to construct an ideal oval shape based on the average of their facial shape dimensions. Twenty-one full-face photographs of purportedly beautiful female actors, performers, and pageant winners were analyzed and an oval constructed from their facial parameters. Only 3 of the 21 faces were totally symmetrical, with the most larger in the left upper and lower face. The average oval was subsequently constructed from an average bizygomatic distance (horizontal parameter) of 4.3 times their intercanthal distance (ICD) and a vertical dimension that averaged 6.3 times their ICD. This average oval could be fitted to many of the individual subjects showing a smooth flow from the forehead through temples, cheeks, jaw angle, jawline, and chin with all these facial aspects abutting the oval. Where they did not abut, treatment may have improved these subjects.

    Full Text Available This article studies variation in regional sex ratios in Finland and outlines potential implications of the skewed sex ratios for family formation patterns. Difficulties in finding a suitable partner are typically mentioned as one of the most important reasons for remaining childless, and we explore if this reason is apparent structurally at the regional macro level. We found significant variation in sex ratios in age-groups 18–30 at the regional and sub-regional levels. Of the whole 20–29-year old population in Finland, almost 50 percent live in sub-region areas with a male surplus. As expected, a higher proportion of men compared to women appears to increase fertility of women in younger age groups. Contrary to expectations, high male-female ratios were not related to higher proportion of women living with a partner

    For nearly twenty five years, EDF has been checking that the actual operating transients are neither more severe nor more numerous than the design basis transients. This activity of transient cycle counting and bookkeeping has enabled EDF to own a database of more than 800 reactor.years for the PWR units. The current method of transient cycle counting is presented. In the paper, we will point out the main results of transient cycle counting and lessons learned. In general, the frequencies of transients are lower than the design frequencies. In few cases, they are higher, such as the transient frequencies of the RCS lines connected to auxiliary systems often due to operating procedures or particular periodic testing. Few periodic tests were not taken into account in the design basis transient file ; they have been detected thanks to the transient cycle counting. In the last 1980's, we achieved the first updating of the design basis transient file for the PWR 900 MWe series. In the early 1990's, we updated the design basis transient file of the PWR 1300 MWe series. In fact, since design and start-up, the operating conditions have been modified (fuel cycle with stretch-out, modification of the hot leg and cold leg temperatures for the PWR 1300 MWe,...). This was the cause of many unclassified transients. In the new design basis transient file, we have created new transients and increased the frequencies of some of them. This has enabled to consider the updated design basis transient file more representative of actual operating transients. For some years, we have increasingly associated the operators with the transient cycle counting concern. We noticed progress (decreased frequencies of most transients). (authors)

    While there are many opinions on what mathematical modeling in biology is, in essence, modeling is a mathematical tool, like a microscope, which allows consequences to logically follow from a set of assumptions. Only when this tool is applied appropriately, as microscope is used to look at small items, it may allow to understand importance of specific mechanisms/assumptions in biological processes. Mathematical modeling can be less useful or even misleading if used inappropriately, for example, when a microscope is used to study stars. According to some philosophers (Oreskes et al., 1994), the best use of mathematical models is not when a model is used to confirm a hypothesis but rather when a model shows inconsistency of the model (defined by a specific set of assumptions) and data. Following the principle of strong inference for experimental sciences proposed by Platt (1964), I suggest "strong inference in mathematical modeling" as an effective and robust way of using mathematical modeling to understand mechanisms driving dynamics of biological systems. The major steps of strong inference in mathematical modeling are (1) to develop multiple alternative models for the phenomenon in question; (2) to compare the models with available experimental data and to determine which of the models are not consistent with the data; (3) to determine reasons why rejected models failed to explain the data, and (4) to suggest experiments which would allow to discriminate between remaining alternative models. The use of strong inference is likely to provide better robustness of predictions of mathematical models and it should be strongly encouraged in mathematical modeling-based publications in the Twenty-First century.

    It is shown in this paper that the D-He-3 fusion fuel cycle is not only credible from a physics standpoint, but that its breakeven and ignition characteristics could be developed on roughly the same time schedule as the DT cycle. It was also shown that the extremely low fraction of power in neutrons, the lack of significant radioactivity in the reactants, and the potential for very high conversion efficiencies, can result in definite advantages for the D-He-3 cycle with respect to DT fusion and fission reactors in the twenty-first century. More specifically, the D-He-3 cycle can accomplish the following: (1) eliminate the need for deep geologic waste burial facilities and the wastes can qualify for Class A, near-surface land burial; (2) allow inherently safe reactors to be built that, under the worst conceivable accident, cannot cause a civilian fatality or result in a significant (greater than 100 mrem) exposure to a member of the public; (3) reduce the radiation damage levels to a point where no scheduled replacement of reactor structural components is required, i.e., full reactor lifetimes (approximately 30 FPY) can be credibly claimed; (4) increase the reliability and availability of fusion reactors compared to DT systems because of the greatly reduced radioactivity, the low neutron damage, and the elimination of T breeding; and (5) greatly reduce the capital costs of fusion power plants (compared to DT systems) by as much as 50 percent and present the potential for a significant reduction on the COE. The concepts presented in this paper tie together two of the most ambitious high-technology endeavors of the twentieth century: the development of controlled thermonuclear fusion for civilian power applications and the utilization of outer space for the benefit of mankind on Earth

  19. Gendering inequality: a note on Piketty's Capital in the twenty-first century.

    2014-12-01

    Thomas Piketty's Capital in the Twenty-First Century is remarkable for moving inequality from the margins to mainstream debate through detailed analysis of longitudinal statistics and, for an economist, by advocating an interdisciplinary perspective and writing in a witty and accessible style. With reference to the post 1970 period, when wage increases are largely responsible for the increase in inequality, Piketty shows how patrimonial capitalists (elite managers) in the top decile and centile of the distribution appropriate a growing share of social wealth as a consequence of their 'power to set their own remuneration' in the context of tolerant social norms rather than through their productive contributions. Piketty raises but defers the question of where these social norms come from to other disciplines. A Feminist Economics perspective indicates that these questions are central to a more inclusive form of economic analysis and such an approach would enrich Piketty's analysis in two main ways. First, by paying greater attention to the processes and social norms through which inequalities are produced and justified and second by highlighting the ways in which inequality is experienced differently depending not only on class, but also on other aspects of identity including gender. This approach also suggests that it is necessary to supplement the ex-post redistributive policies recommended by Piketty: a global wealth tax and more steeply progressive income tax, with ex-ante measures to stop the rise in wage inequality in the first place, especially by bridging the huge gulf that exists between those who care for people and those who manage money. © London School of Economics and Political Science 2014.

    Driving after brain damage is a vital issue, considering the large number of patients who suffer from cerebrovascular and traumatic encephalopathy. The ability to operate a motor vehicle is an integral part of independence for most adults and so should be preserved whenever possible. The physician may estimate a patient's ability to drive safely based on his own examination, the evaluation of a neuropsychologist, and a comprehensive driving evaluation--testing, driving simulation, behind-the-wheel observation--with a driving specialist. This study sought to evaluate the ability of brain-damaged individuals to operate a motor vehicle safely at follow-up. These patients had been evaluated (by a physician, a neuropsychologist, and a driving specialist) and were judged able to operate a motor vehicle safely after their cognitive insult. Twenty-two brain-damaged patients who were evaluated at our institution were successfully followed up to five years (mean interval of 2.67 years). Patients were interviewed by telephone. Their driving safely was compared with a control group consisting of a close friend or spouse of each patient. Statistical analysis revealed no difference between patient and control groups in the type of driving, the incidence of speeding tickets, near accidents, and accidents, and the cost of vehicle damage when accidents occurred. The patient group was further divided into those who had, and those who had not experienced driving difficulties so that initial neuropsychologic testing could be compared. No significant differences were noted in any aspect of the neuropsychologic test battery. We conclude that selected brain-damaged patients who have passed a comprehensive driving assessment as outlined were as fit to drive as were their normal matched controls.(ABSTRACT TRUNCATED AT 250 WORDS)

    2014-12-01

    Full Text Available The aim of this paper is to analyze fundamental factors which form and profoundly shape security and defense policy of the Republic of Latvia. One can argue that historical background, geographical location, common institutional history within the former Soviet Union, the Russia factor, the relative smallness of the territory of state and the population, the ethnic composition of the population, the low density of the population and rather limited financial and manpower resources available for the defense of the Republic of Latvia are the key factors of influence on the state security and defense policy. The core principles of the security and defense policy of Latvia are the membership in powerful global military alliance of NATO and bilateral strategic partnership with the United States. However, security and defense cooperation among the three Baltic States as well as enhanced cooperation within the Baltic-Nordic framework is seen as an important supplementary factor for the increased security of the Republic of Latvia. Latvia has developed a sustainable legal and institutional framework in order to contribute to state security and defense; however, security challenges and significant changes within the global security environment of the twenty-first century will further challenge the ability of the Republic of Latvia to sustain its current legal framework, and more importantly, current institutional structure of Latvian security and defense architecture. Significant internal and external challenges will impact the fundamental pillars of Latvian security and defense policy, such as American strategic shift to the Pacific, and lack of political will to increase defense budgets in European part of NATO. It has to be clear that very independence, security and defense of the Republic of Latvia depend on the ability of NATO to remain an effective organization with timely and efficient decision-making, and the ability of the United States to remain

    The first Summer Institute in Clinical Dental Research Methods, a faculty development program at the University of Washington, was offered in the summer of 1992 for sixteen participants. The primary objective of the program was to give clinical faculty members in dentistry an introduction to and an understanding of the fundamental principles and methods used in good clinical research. In the twentieth offering of the institute in 2011, there were thirty-five participants, and over the twenty institutes, there has been a cumulative total of 463 participants who have come from thirty U.S. states as well as forty-three countries outside the United States. The curriculum has expanded from the initial offering of biostatistics, clinical epidemiology, behavioral research methods, and ethics in clinical research to now include clinical trials, grantsmanship, data analysis, an elective in molecular biology, and a team project that provides participants with hands-on experience in research proposal development as members of an interdisciplinary team. Enrollment has doubled since the first year, yet exit evaluations of the program content have remained consistently high (rated as very good to excellent). One of the indicators of program quality is that at least 50 percent of recent participants indicated that they attended because the program was recommended by colleagues who had attended. There seems to be an ever-increasing pool of dental faculty members who are eager to learn more about clinical research methodology through the institute despite the intensive demands of full-time participation in a six-week program.

  4. Higher Alu methylation levels in catch-up growth in twenty-year-old offsprings.

    Full Text Available Alu elements and long interspersed element-1 (LINE-1 or L1 are two major human intersperse repetitive sequences. Lower Alu methylation, but not LINE-1, has been observed in blood cells of people in old age, and in menopausal women having lower bone mass and osteoporosis. Nevertheless, Alu methylation levels also vary among young individuals. Here, we explored phenotypes at birth that are associated with Alu methylation levels in young people. In 2010, 249 twenty-years-old volunteers whose mothers had participated in a study association between birth weight (BW and nutrition during pregnancy in 1990, were invited to take part in our present study. In this study, the LINE-1 and Alu methylation levels and patterns were measured in peripheral mononuclear cells and correlated with various nutritional parameters during intrauterine and postnatal period of offspring. This included the amount of maternal intake during pregnancy, the mother's weight gain during pregnancy, birth weight, birth length, and the rate of weight gain in the first year of life. Catch-up growth (CUG was defined when weight during the first year was >0.67 of the standard score, according to WHO data. No association with LINE-1 methylation was identified. The mean level of Alu methylation in the CUG group was significantly higher than those non-CUG (39.61% and 33.66 % respectively, P < 0.0001. The positive correlation between the history of CUG in the first year and higher Alu methylation indicates the role of Alu methylation, not only in aging cells, but also in the human growth process. Moreover, here is the first study that demonstrated the association between a phenotype during the newborn period and intersperse repetitive sequences methylation during young adulthood.

    A novel paper-based Nanoceria Reducing Antioxidant Capacity (NanoCerac) assay for antioxidant detection (Sharpe, Frasco, Andreescu, & Andreescu, 2012), has been adapted for the first time as a high-throughput method, in order to measure the effect of brewing conditions and re-infusion on the antioxidant capacity of twenty-four commercial green teas. The oxygen radical absorbance capacity (ORAC) assay, frequently applied to complex foods and beverages, was used as a comparator measure of antioxidant capacity. A novel measure of sustained antioxidant capacity, the total inherent antioxidant capacity (TI-NanoCerac and TI-ORAC) was measured by infusing each tea six times. Effects of brewing conditions (temperature, brew time, etc.) were assessed using one popular tea as a standard. Both NanoCerac and ORAC assays correlated moderately (R(2) 0.80 ± 0.19). The average first-brew NanoCerac, TI-NanoCerac, first-brew ORAC and TI-ORAC were: 0.73 ± 0.1 GAE/g tea; 2.4 ± 0.70 mmolGAE/g tea; 1.0 ± 0.3 mmolTE/g tea and 2.1 ± 0.71 mmolTE/g tea respectively. Brewing conditions including water temperature and infusion time significantly affected antioxidant capacity. The high-throughput adaptation of the original NanoCerac assay tested here offered advantages over ORAC, including portability and rapid analysis. Copyright © 2015 Elsevier Ltd. All rights reserved.

  6. Some Observations on Cultural Opposites in Contemporary China: Kunming and Beijing Twenty Years Later

    Directory of Open Access Journals (Sweden)

    Vesna Vučinić-Nešković

    2016-02-01

    Full Text Available This paper considers the cultural opposites observed in various segments of Chinese culture during the author's three stays in China over a period of twenty years. The first and second stay, in 1986 and 1989 respectively, coincided with the initial period of the implementation of modernization reforms in China, when their results were just beginning to be felt. The third stay was in 2009, towards the end of the third decade of reform implementation, at the time of an already developed marketoriented communism. The paper's main thesis is that most of the phenomena observed in present-day urban China can be assigned to opposite categories, namely Chinese-Western and traditional- contemporary. Cultural opposites have been observed in the sphere of tourism and the behavior of both Chinese and foreign visitors, in the use of Chinese and English in notices and signs in public places, and in the promotion of traditional and modern architecture. In addition, they have been noted in the presentation of arts and crafts and industrial products, in the manner of consumption of hot drinks, and in the combining of Chinese and foreign cuisine. They are also evident in a Beijing Opera performance adapted both to the modern Chinese and to foreigners, and in the traditional Chinese exercises and western dances performed in public parks. In conclusion, the paper suggests that the process of establishing connections between China and the West is being carried on in a moderate and controlled way. In the globalization process cultural opposites coexist and merge, imparting new features to Chinese culture.

    This is the Japanese translation of the Ukrainian National Report 'Twenty-five Years after Chernobyl Accident: Safety for the Future', published by the Ministry of Ukraine of Emergencies in 2011 (in Ukrainian and English). This Japanese translation is published as an outcome of the KAKENHI research project on liquidations of Nuclear Disasters in the World (headed by Tetsuji Imanaka), in which Shindo participates, and as a KUR report of the Research Reactor Institute at Kyoto University. The objective of publishing this Japanese translation is to provide basic information on how to overcome the consequences of a large-scale Nuclear Disaster for the wide range of public, including decision-makers and administrative staff. By doing so, this publication aims at invigorating discussions over measures to be applied for overcoming the consequences of the TEPCO Nuclear Disaster (started in 11th March 2011 at Fukushima), and at forming proper schemes to minimise the consequences on current and future generations. The original text of this translation tightly summarised the whole picture of the Chernobyl Nuclear Disaster, which had been the only large-scale Nuclear Disaster until 11th March 2011. More importantly, it describes all sorts of measures and schemes taken in Ukraine from 1986 to 2011 in order to overcome the consequences of the Chernobyl Nuclear Disaster, in a quite well structured manner. In other words, from the contents of this text, Japanese readers are able to learn a lot about the very problems currently facing with. Therefore, I wish many Japanese readers will read this text, and utilise the knowledge written here effectively to overcome the consequences of the TEPCO Nuclear Disaster. (J.P.N.)

    Full Text Available In accord with the promise made by Henry Jenkins that “old and new media will interact in ever more complex ways” (Convergence Culture 6, this research observes metamodern fairy tale adaptations of the twenty-first century in light of Christina Bacchilega’s construct of the fairy-tale web and Henry Jenkins’ theory of convergence culture and transmedia storytelling. The research will address the growing trend of embedding “wonder tale” collections within the context of a larger narrative as an artefact of significance, power, and material value. Although original tales with known authorship, these fairy tale adaptations are appended to the mythology and culture of the fantastic secondary worlds. Such texts tend to be parodic, subversive, and even carnivalesque (Bakhtin; Stephens, providing a commentary on the culture of their origin, as well as our own. By blending cultures, styles, and formats, mise en abyme wonder tales also result in the empowerment of specifically marginalised groups. Generally defined as spin-offs that are otherwise a part of a complex inter- and hypertextual web, these fairy tale collections constitute a metafictional body of knowledge and wisdom. In the digital era much focus is placed on multimodal, hypertextual, and transmedia narratives with a significant influence of fandom on the production of such literary works. The study will focus on the popular examples of such practice, J.K. Rowling’s Tales of Beedle the Bard (2007/2008 and Ransom Riggs’ Tales of the Peculiar (2016, in order to define mise en abyme fairy tale adaptations, as well as to discuss their cultural significance and function.

    Full Text Available Interest in mung bean (Vigna radiata L. as a functional food is growing; however, studies on the nutritional composition of major mung bean cultivars planted in China are limited. Twenty Chinese mung bean cultivars were collected and their nutritional compositions including starch, fat, protein, and phytochemicals were analyzed. The cultivars were found to have a high amount of resistant starch, accounting for 16.1%–22.3% of total starch, and balanced amino acid constitutions. Palmitic acid and linoleic acid were the two dominant fatty acids, accounting for respectively 32.4% and 36.1% of all of the assayed fatty acids. Four bound phenolic acids (syringic, caffeic, p-coumaric, and ferulic acids and two free phenolic acids (caffeic and ferulic acids were identified by HPLC. The antioxidant activity of 70% ethanol extracts from the 20 mung bean cultivars was evaluated. Their DPPH and ABTS+ free-radical-scavenging capacity ranged from 28.13 ± 2.24 to 35.68 ± 0.71 μmol g−1 and from 3.82 ± 0.25 to 13.44 ± 1.76 μmol g−1, respectively. Significant positive correlations of ABTS+ free-radical-scavenging capacity with total phenolic acids and total flavonoid contents were observed. These results suggest that Chinese mung bean cultivars are rich in balanced nutrients and that their phytochemicals should be considered as potential sources of natural antioxidants.

Findings: The study proves that women in Mexico are motivated by a combination of push and pull factors, where the majority of the factors are pull factors. The findings of the study help to conclude that female entrepreneurship development is influenced by different factors including the entrepreneurs’ personal traits, social and economic factors. Due to their conservative traditional attitude, risk adverse tendency, and non-cooperation of family members, etc. women entrepreneurs are sometimes deterred to start a business in Mexico. Implications & Recommendations: It is necessary to raise the awareness of different factors that promote female entrepreneurship in Mexico. Governmental programmes which support female entrepreneurship, business incubators, and networking could be very helpful for women when starting their own business. Contribution & Value Added: The originality of this work lies in studying motivational factors for female entrepreneurship in Mexico. The Mexican society faces a big revolution towards female entrepreneurship. Based on the change of family structure and traditions, women nowadays are having more opportunities to develop as entrepreneurs.

  12. Female Clergy as Agents of Religious Change?

    Full Text Available This article focuses on female clergy as potential agents of change in the Church. I argue that the adoption of female clergy is one of the main factors that cause the Church to change its practices, policies and theological orientation. The first female ministers were ordained in the Evangelical Lutheran Church of Finland in 1988. This is fairly late compared to other Nordic countries. However, the number of female ministers and female students has been growing fast and nowadays about 70 percent of theology students are female.The paper is based on quantitative surveys conducted among the members of the Clergy Union in 2002, 2006 and 2010 (N = about 1,000 each and among the applicants for university studies in theology in 2010. The research shows that clergywomen are changing the Church in a clearly more liberal direction. They do it in various areas of church life: they change the perception of faith and dogma, the policies of the Church as well as daily practices in parishes. Clergymen are notably more traditional in their orientation, even young clergymen. Therefore it is especially the female clergy who serve as agents of religious change in the Church.

  13. Female headship, feminization of poverty and welfare.

    Female-headed households are at greater risk of slipping into poverty than male-headed households. Indeed, sex and marital status of the head of household are the most important determinants of a family's poverty status in the US. Divorce, separation, death of a husband, and out-of-wedlock births can lead to female headship. Transfer payments, especially the Aid to Families with Dependent Children program, are blamed for contributing to increased marital instability and out-of-wedlock births. The authors examined the role of welfare benefits in influencing female headship. Preliminary results using standard estimation procedures indicate that transfers do not significantly influence female headship. Standard estimation procedures are, however, erroneous because they ignore differences in propensities to establish mother-only households. Therefore, adjusting for differences in propensities to establish female-headed households, the level of welfare benefits is indeed an important factor in explaining the variation in the changes in the birth rates to unmarried women. The use of a weighted measure suggests that welfare benefits, by increasing female headship of women who otherwise have low propensities to be female heads, have played a significant role in the feminization of poverty.

  14. Male and Female Perception of Physical Attractiveness

    Full Text Available Waist-to-hip ratio (WHR and breast size are morphological traits that are associated with female attractiveness. Previous studies using line drawings of women have shown that men across cultures rate low WHRs (0.6 and 0.7 as most attractive. In this study, we used additional viewing measurements (i.e., first fixation duration and visual regressions to measure visual attention and record how long participants first focused on the female body and whether they regressed back to an area of interest. Additionally, we manipulated skin tone to determine whether they preferred light- or dark-skinned women. In two eye tracking experiments, participants rated the attractiveness of female nude images varying in WHR (0.5–0.9, breast size, and skin tone. We measured first fixation duration, gaze duration, and total time. The overall results of both studies revealed that visual attention fell mostly on the face, the breasts, and the midriff of the female body, supporting the evolutionary view that reproductively relevant regions of the female body are important to female attractiveness. Because the stimuli varied in skin tone and the participants were mainly Hispanic of Mexican American descent, the findings from these studies also support a preference for low WHRs and reproductively relevant regions of the female body.

  15. Female Sex Offenders: Public Awareness and Attributions.

    Cain, Calli M; Anderson, Amy L

    2016-12-01

    Traditional gender roles, sex scripts, and the way female sex offenders are portrayed in the media may lead to misconceptions about who can commit sexual offenses. Sexual crimes by women may go unnoticed or unreported if there is a general lack of awareness that females commit these crimes. Data from the 2012 Nebraska Annual Social Indicators Survey were used to determine whether the public perceives women as capable sex offenders and the perceived causes of female sex offending. The traditional focus on male sex offenders by researchers, media, and politicians, in addition to gender stereotypes, introduces the possibility of group differences (e.g., between men and women) in perceptions of female sex offenders. Consequently, two secondary analyses were conducted that tested for group differences in both the public's perception of whether females can commit sex offenses and the explanations selected for why females sexually offend. The findings suggest that the public does perceive women as capable sex offenders, although there were group differences in the causal attributions for female sex offending.

  18. Characteristics of Female Solo and Female Co-Offenders and Male Solo Sexual Offenders Against Children.

    2017-09-01

    Studies have highlighted differences in the victim choice, offender, and offense characteristics of female and male sexual offenders. However, little is known about how solo and co-offending females differ from solo male sexual offenders. We compared the characteristics of 20 solo and 20 co-offending females (co-offended with a male and/or female accomplice), and 40 male sexual offenders against children. We found that solo female offenders showed the most evidence of personal problems, including depression and sexual dissatisfaction. Compared with male offenders, female co-offenders showed poorer self-management, but better sexual self-regulation. Male offenders had a greater history of offending and showed more evidence of sexual abuse supportive cognitions relative to both solo and co-offending females. These results are consistent with the need for a gender-specific approach to working with sexual offenders and may have implications for understanding the often complex treatment needs of these clients.

    Full Text Available ABSTRACT The purpose of this study was to determine live weight and body measurements of male and female native ducks raised in different raising systems. One hundred and twenty native ducks (60 males, 60 females were used in the study. The ducks were raised in deep litter floor and cage systems. Live weight and body values were measured every two weeks, until they were 56 days old. Three-parameter logistic regression and Gompertz model were used to determine growth model of male and female ducks. Interactions of time-raising system and time-sex were statistically significant in terms of live weight. At the end of eight weeks, live weights of ducks raised in deep litter floor were higher than ducks raised in cage system. In addition, live weights of male ducks were higher than female ducks. Consequently, deep litter floor is more appropriate for live weight in native ducks. Accuracy rate of Three-parameter Logistic and Gompertz models for estimation of growth in ducks was between 0.91-0.95 and similar results were obtained from both models. The Gompertz model is appropriate for the data structure of this study because it contains fewer iterations than the Three-Parameter Logistic model.

  20. Status epilepticus during early development disrupts sexual behavior in adult female rats: recovery with sexual experience.

    Female sexual behavior is sensitive to stress and diseases. Some studies have shown that status epilepticus (SE) can affect sexual proceptivity and receptivity in female rats and also increases reject responses towards males. However, epidemiologic studies indicate that SE is more frequent in young individuals. Herein, we assessed the effects of SE in infant females on their sexual behavior during adulthood. Thirteen-day-old (P13) rat pups received intraperitoneal injections of lithium chloride (3 mEq/kg). Twenty hours later, at P14, SE was induced by subcutaneous injection of pilocarpine hydrochloride (100 mg/kg s.c.). Control animals were given an equal volume of saline subcutaneously. The animals were weaned at P21 and, later in adulthood, were ovariectomized and hormone-primed with estradiol+progesterone, and their sexual behavior assessed during 4 separate trials of 30 min each with a stud male. Our results indicate that proceptive behaviors (solicitations and hops and darts) were impaired during the first trial, but no alterations were observed for receptivity and attractivity. By trial 3, all SE females displayed normal proceptivity. These results indicate that SE in infancy readily affects proceptivity in a reversible manner. We discuss the role of sexual experience in recovery. Copyright © 2014 Elsevier Inc. All rights reserved.

    Many cases of dermatologic complication were reported with the use of skin lightening products. This study assessed the skin lightening practice and health symptoms among female students. Self-administered questionnaire was distributed to 104 female students (56 undergraduates and 48 postgraduates) aged 24 ± 2 years in Universiti Putra Malaysia. A total of 60.6% (N = 63) of the female students used skin lightening products (61.9% of undergraduates and 38.1% of postgraduates). Reasonable price (N = 35, 55.6%) and ingredients (N = 29, 46%) were considered the most important factors in the product selection. Most respondents purchased the product from drugstores (N = 39, 61.9%). Twenty-two respondents (34.9%) in this study experienced skin problem from the products they used. Skin peeling (N = 13, 12.5%) and acne (N = 9, 8.7%) were the most frequent symptoms experienced. Most of the respondents have the perception that lighter skin provides high self-esteem (N = 56, 53.8%) and looks beautiful and healthier (N = 54, 51.9%). The use of skin lightening products is common among female students in this study and some of these products can cause skin problems such as skin peeling, acne, and itching.

    Female urethral diverticulum is a localized out-pouching of the urethra that is becoming increasingly prevalent, but often poses a diagnostic challenge. Traditionally, conventional voiding cystourethrography has been used to make the preoperative diagnosis. With the development of higher-resolution images acquired through ultrasonography (US), computed tomography (CT), and magnetic resonance imaging (MRI), the anatomy and various abnormalities of the female urethra can be better elucidated. This article focuses on the imaging features of female urethral diverticulum, with emphasis on diagnostic pearls, particularly using MRI. Female urethral diverticulum can be best identified by their location in the posterolateral urethra and by their communication with the urethral lumen. Improved imaging techniques combined with increased physician awareness of urethral diverticulum will lead to more prompt and accurate diagnosis of this entity, leading to better treatment of affected patients

    The aim of this study was to examine the relation between increased physical activity and menstrual disorders in adolescent female volleyball players. The study was conducted on 210 Polish female volleyball players, aged 13-17 years, the authorship questionnaire was used. The results of the study showed that irregular menstruation occurred in 19% of girls, spotting between menstrual periods in 27% and heavy menstruation was reported in 33% of girls. Out of all volleyball female players participating in the study, 94 girls (45%) declared absence of menstrual periods after regular cycles. Statistical analysis showed that the more training hours per week, the bigger probability of the occurrence of irregular menstruation. It was concluded that the number of hours of volleyball training per week affects regularity of menstrual cycles in female volleyball players. The absence of menstruation might be caused by the duration of training per week or years of training.

    2013-09-01

    Full Text Available Female genital mutilation (FGM, sometimes referred to as female circumcision or female genital cutting, is a harmful cultural practice without any known health benefit. Its short-term and long-term health risks have led to numerous initiatives toward its eradication at international and local levels, over the last two decades. While major challenges remain and millions of girls and women are still at risk of being subjected to FGM, there is growing evidence that interventions that take into account the social dynamics that perpetuate FGM are yielding positive results toward its reduction. Well-recognized as a human rights violation in international treaties, the elimination of female genital mutilation requires ongoing interventions through cross-sectoral approaches that address attitudinal, cultural and behavioral change.

    When "woman-the-gatherer" was first proposed as a counter to "man-the-hunter," we were only beginning to understand the many faces of primate females. In ensuing decades we have learned about the skills and talents of female chimpanzees in tool using, hunting, and transmitting behaviors from one generation to the next as teachers, and across space as newcomers to neighboring communities. The perspective of evolutionary time highlights the continuity of female lives from the origin of mammals to the origin of Homo sapiens. The combination of behavioral, fossil, and archeological information aid in reconstructing key ingredients acquired by females along the way that contributed to the success of our species.

    2000-06-01

    Female sexuality has received little scientific study. Recently, increased interest in this field has generated new research in the epidemiology, pathophysiology, and pharmacotherapy of female sexual dysfunction (FSD). A new FSD classification system has been proposed. Although sexual difficulties are highly prevalent among women, the degree of associated distress is unknown. Risk factors for FSD are probably both psychologic and physiologic. Aging or menopause is associated with lubrication difficulties, which can be treated with hormone replacement. Hysterectomy seems more likely to result in improvement rather then deterioration of sexual functioning. Depression may be a predictor of sexual dysfunction after hysterectomy. Vasoactive agents are currently being evaluated as treatment for female sexual arousal disorder. The most important advance in the study of female sexual function is the recent surge of interest in this relatively unexplored field.

  18. Genetic diversity studies in twenty accessions of hot pepper (Capsicum spp L.) in Ghana

    International Nuclear Information System (INIS)

    Doku, S.K.

    2015-07-01

    Twenty (20) accessions of hot pepper (Capsicum spp L.) were collected from eight geographical regions of Ghana for genetic diversity studies. The objective was to assess genetic relationship among them using phenotypic and molecular traits and to evaluate their elemental composition. A replicated field experiment was conducted to assess their genetic diversity based on 13 quantitative traits and 22 qualitative traits using the IBPGR descriptor list for Capsicum. Confirmation of their identities was done using 10 SSR markers. The accessions were also evaluated for macro, micro and trace elements in their fresh fruits using the Instrumental Neutron Activation Analysis (INAA). Five essential macro elements (Ca, Cl, K, Mg and Na), two micro elements (Al and Mn) and one trace element (Br) were detected by INAA. Results from the agromorphological study revealed that accession Wes 01 had the widest stem width, matured leaf width, high fruit set but late maturing. Nor 03 was early maturing and had high fruit set, but also possessed the highest number of seeds per fruit. Fruit weight, fruit width, fruit length and plant canopy width, recorded the highest variabilities with 66.191; 53.24; 49.32; and 32.42 coefficients of variation (CVs), respectively. Few traits such as plant canopy width, plant height, fruit length, mature leaf length and number of seeds per fruit contributed substantially to total genetic variance as revealed by the principal component analysis (PCA). A dendrogram generated using morphological traits grouped accessions into cultivated and wild genotypes of pepper and all the accessions were identified as separate entities with no duplications. Strong correlation was recorded between plant canopy width and plant height, mature leaf length and mature leaf width, and also fruit weight and fruit width and fruit length. Negative correlation was however, observed between fruit length and days to 50% fruiting and flowering. All three accessions from the Northern

  19. Twenty-five years of modeling multiphase flow and heat transfer

    International Nuclear Information System (INIS)

    Lyczkowski, R.W.

    1999-01-01

    This presentation will cover some of the highlights of multiphase modeling in collaboration with Professor Dimitri Gidaspow (DG) over the last roughly twenty-five years. It all started in 1972 in Idaho Falls with Charles Solbrig, who planned and initiated a project for the former USAEC to develop a computer code to replace RELAP4 to analyze the loss of coolant accident (LOCA). DG spent his sabbatical on the project in 1973. One highlight was the discovery of complex characteristics, the implications of which are still pondered by some. Fluidization research began in 1978 when the author collaboratively developed a step-by-step building-block approach to understanding the hydrodynamics of fluidized beds, an approach closely coupled to validation experiments. A grant from the USDOE to study solids circulation around a jet in a fluidized bed was awarded to DG in 1978. Following that, grants from GRI, NSF, and a contract from Westinghouse Electric Corp. allowed the early work to continue. Progress was slow since computer costs were high. Subsequent continuing support from the USDOE, NSF, EPRI, and industry has allowed research to continue, as has his collaboration. A highlight of this collaboration was the development of the monolayer energy dissipation (MED) erosion model. Multiphase flow and fluidization theory took quantum leaps with the publication of DG's Multiphase Flow and Fluidization: Continuum and Kinetic Theory Descriptions (MFF), Academic Press, San Diego (1994), for which there is essentially no competition. Only the late Professor S.L. Soo's Particulates and Continuum: Multiphase Fluid Dynamics, Hemisphere Publishing Corp., New York (1989), a textbook version of the classic monograph Multiphase Fluid Dynamics, Science Press, Beijing, China (1990), comes close. In MFF, the kinetic theory of granular flow has evolved as a potentially viable adjunct to the continuum multiphase theory, of which fluidization is one important manifestation. It must be

  20. Learning by Doing: Twenty Successful Active Learning Exercises for Information Systems Courses

    Directory of Open Access Journals (Sweden)

    Alanah Mitchell

    2017-01-01

    Full Text Available Aim/Purpose: This paper provides a review of previously published work related to active learning in information systems (IS courses. Background: There are a rising number of strategies in higher education that offer promise in regards to getting students’ attention and helping them learn, such as flipped classrooms and offering courses online. These learning strategies are part of the pedagogical technique known as active learning. Active learning is a strategy that became popular in the early 1990s and has proven itself as a valid tool for helping students to be engaged with learning. Methodology: This work follows a systematic method for identifying and coding previous research based on an aspect of interest. The authors identified and assessed research through a search of ABI/Inform scholarly journal abstracts and keywords, as well as additional research databases, using the search terms “active learning” and “information systems” from 2000 through June 2016. Contribution: This synthesis of active learning exercises provides guidance for information technology faculty looking to implement active learning strategies in their classroom by demonstrating how IS faculty might begin to introduce more active learning techniques in their teaching as well as by presenting a sample teaching agenda for a class that uses a mix of active and passive learning techniques to engage student learning. Findings: Twenty successful types of active learning exercises in IS courses are presented. Recommendations for Practitioners\t: This paper offers a “how to” resource of successful active learning strategies for IS faculty interested in implementing active learning in the classroom. Recommendation for Researchers: This work provides an example of a systematic literature review as a means to assess successful implementations of active learning in IS. Impact on Society: An updated definition of active learning is presented as well as a meaningful

  1. Commercial NAA — Is It a Success? Evaluation of a Twenty Year Experiment

    International Nuclear Information System (INIS)

    Parry, S.

    2013-01-01

    The commercial service at Imperial College was maintained for twenty years by juggling staff, equipment and irradiation facilities, building when required and downsizing when necessary. At no point was the service entirely self-sufficient since staff had more than one role and participated in teaching and research as well as the analytical service. The balance was of benefit everyone concerned, including students who have studied with us and gained experience of working within a well maintained and quality assured laboratory. The benefits of collaborating with industry cannot be overestimated, with the secondary effects for research and teaching identified previously. A key change took place in the early 2000s, which can be seen in Figure 5 by the fall in income from 2002. The author’s academic department became a separate cost centre to the Reactor Centre, and irradiations were charged at a more realistic price. Once the true costs were built in, including space, overheads and irradiation charges, it was not possible to maintain a viable business plan without reducing staff to a non-viable number. As a result, in 2003 the analytical service was handed to the Reactor Centre, in which the business could remain viable because the irradiation charge became income not expenditure. Without the continued interactions that academic research generated, the NAA service has diminished with very few customers in the past few years. Staff are occupied with internal work for the reactor such as routine monitoring using gamma spectrometry. In summary the introduction and operation of a commercial service is to be recommended, particularly in those situations where it can complement other parts of the organisation such other analytical or academic activities. It is not practical to fund reactor operations entirely on commercial activities, but it can result in a number of spin-offs that can increase other income streams such as teaching and research projects. Over the past 28

  2. Ten Years, Twenty Issues, and Two Hundred Papers of Numeracy: Toward International Reach and Transdisciplinary Utility

    2017-07-01

    Full Text Available This issue completes the first ten years of Numeracy. The purpose of this introductory editorial is to review what has happened to the journal in those ten years. In the twenty issues, Numeracy’s output has been 201 papers counting the one or two editorials per issue. More than 50% of the papers are full, peer-reviewed articles, including 13 papers in two theme collections. The others are peer-reviewed notes and perspectives, editor-reviewed book reviews (15% of the total, and a column by contributing co-editor, Dorothy Wallace. The current issue marks an upswing in the number of notes, and our first discussion/reply. The number of papers per year has been increasing (e.g., 66% more in the last three years than in the first three years. The download rate has increased from about 5,000 in the first two years to 5,000 in about 40 days now. The editorial goes on to document two main outcomes. First, the journal is gaining an international reach: more than half the downloads occur outside the United States now, and the number of contributions from outside the United States has increased from 4 in the first five years to 15 in the second five years. Second, the across-the-curriculum nature of quantitative literacy is coming to the fore. The transdisciplinarity of QL is strikingly evident in this issue, which is discussed in some detail, especially how it conforms to the mission of the Association of American Colleges and Universities.

    As the number of studies in the literature is increasing, orthopaedic surgeons highly depend on meta-analyses as their primary source of scientific evidence. The objectives of this review were to assess the scientific quality and number of published meta-analyses on orthopaedics-related topics over time. We conducted, in duplicate and independently, a systematic review of published meta-analyses in orthopaedics in the years 2005 and 2008 and compared them with a previous systematic review of meta-analyses from 1969 to 1999. A search of electronic databases (MEDLINE, EMBASE, and the Cochrane Database of Systematic Reviews) was performed to identify meta-analyses published in 2005 and 2008. We searched bibliographies and contacted content experts to identify additional relevant studies. Two investigators independently assessed the quality of the studies, using the Oxman and Guyatt index, and abstracted relevant data. We included forty-five and forty-four meta-analyses from 2005 and 2008, respectively. While the number of meta-analyses increased fivefold from 1999 to 2008, the mean quality score did not change significantly over time (p = 0.067). In the later years, a significantly lower proportion of meta-analyses had methodological flaws (56% in 2005 and 68% in 2008) compared with meta-analyses published prior to 2000 (88%) (p = 0.006). In 2005 and 2008, respectively, 18% and 30% of the meta-analyses had major to extensive flaws in their methodology. Studies from 2008 with positive conclusions used and described appropriate criteria for the validity assessment less often than did those with negative results. The use of random-effects and fixed-effects models as pooling methods became more popular toward 2008. Although the methodological quality of orthopaedic meta-analyses has increased in the past twenty years, a substantial proportion continues to show major to extensive flaws. As the number of published meta-analyses is increasing, a routine checklist for

    Full Text Available Abstract Background Elevated blood pressure in childhood is a risk factor for adult hypertension which is a global health problem. Excess adiposity in childhood creates a predisposition to develop adult hypertension. Our aim was to explore distinct sex-specific adiposity trajectories from childhood to late adolescence and examined their association with blood pressure. Methods Latent Class Growth Mixture Modeling (LCGMM on longitudinal data was used to derive sex-specific and distinct body mass index (BMI: kg/m2 trajectories. We studied 1824 black children (boys = 877, girls = 947 from the Birth to Twenty (Bt20 cohort from Soweto, South Africa, and obtained BMI measures at ages 5 through 18 years. Participants with at least two age-point BMI measures, were included in the analysis. Analysis of variance (ANOVA, chi-square test, multivariate linear and standard logistic regressions were used to test study characteristics and different associations. Results We identified three (3 and four (4 distinct BMI trajectories in boys and girls, respectively. The overall prevalence of elevated blood pressure (BP was 34.9 % (39.4 % in boys and 30.38 % in girls. Boys and girls in the early onset obesity or overweight BMI trajectories were more likely to have higher BP values in late adolescence. Compared to those in the normal weight BMI trajectory, girls in early onset obesity trajectories had an increased risk of elevated BP with odds ratio (OR of 2.18 (95 % confidence interval 1.31 to 4.20 and 1.95 (1.01 to 3.77. We also observed the weak association for boys in early onset overweight trajectory, (p-value = 0.18 and odds ratio of 2.39 (0.67 to 8.57 Conclusions Distinct weight trajectories are observed in black South African children from as early as 5 years. Early onset adiposity trajectories are associated with elevated BP in both boys and girls. It is important to consider individual patterns of early-life BMI development, so that

    We examined the reproductive performance of female caribou (Rangifer tarandus granti) in relation to age, physical condition, and reproductive experience for 9 consecutive years (1987-95) at Denali National Park, Alaska, during a period of wide variation in winter snowfall. Caribou in Denali differed from other cervid populations where reproductive performance has been investigated, because they occur at low densities (≥0.3/km2) and experience high losses of young to predation. Females first gave birth at 2-6 years old; 56% of these females were 3 years old. Average annual natality rates increased from 27% for 2-year-olds to 100% for 7-year-olds, remained high for 7-13-year-olds (98%), and then declined for females ≥14 years old. Females ≥2 years old that failed to reproduce were primarily sexually immature (76%). Reproductive pauses of sexually mature females occurred predominantly in young (3-6 yr old) and old (≥14 yr old) females. Natality increased with body mass for 10-month-old females weighed 6 months prior to the autumn breeding season (P = 0.007), and for females >1 year old and weighed during autumn (late Sep-early Nov; P = 0.003). Natality for 2-, 3-, 4-, and 6-year-olds declined with increasing late-winter snowfall (Feb-May; P ≤ 0.039) during the winter prior to breeding. In most years, a high percentage of sexually mature females reproduced, and lactation status at the time of breeding did not influence productivity the following year. However, following particularly high snowfall during February-September 1992, productivity was reduced in 1993 for cows successfully rearing calves to autumn the previous year. High losses of calves to predators in 1992 may have increased productivity in 1993. Losses of young-of-the-year to predation prior to the annual breeding season can be an important influence on subsequent productivity for ungulate populations where productivity varies with lactation status of females at the time of breeding.

    Although it is known that prenatal exposure to perfluorooctane sulfonate (PFOS) can cause developmental adverse effects in mammals, the disruptive effects of this compound on hormonal systems are still controversial. Information concerning the effects of PFOS on hypothalamus adrenal (HPA) axis response to stress and corticosterone levels is not currently available. On the other hand, it is well established that stress can enhance the developmental toxicity of some chemicals. In the present study, we assessed the combined effects of maternal restraint stress and PFOS on HPA axis function in the offspring of mice. Twenty plug-positive female mice were divided in two groups. Animals were given by gavage 0 and 6 mg PFOS/kg/day on gestation days 12-18. One half of the animals in each group were also subjected to restraint stress (30 min/session, 3 sessions/day) during the same period. Five plug-positive females were also included as non-manipulated controls. At 3 months of age, activity in an open-field and the stress response were evaluated in male and female mice by exposing them to 30 min of restraint stress. Male and female offspring were subsequently sacrificed and blood samples were collected to measure changes in corticosterone levels at four different moments related to stress exposure conditions: before stress exposure, immediately after 30 min of stress exposure, and recuperation levels at 60 and 90 min after stress exposure. Results indicate corticosterone levels were lower in mice prenatally exposed to restraint. In general terms, PFOS exposure decreased corticosterone levels, although this effect was only significant in females. The recuperation pattern of corticosterone was mainly affected by prenatal stress. Interactive effects between PFOS and maternal stress were sex dependent. The current results suggest that prenatal PFOS exposure induced long-lasting effects in mice.

    The aim of this paper is to analyze the aesthetic characteristics of the human females' gaze using anthropometry and to present an artistic model to represent it: "The Frame Concept." In this model, the eye fissure represents a painting, and the most peripheral shadows around it represent the frame of this painting. The narrower the frame, the more aesthetically pleasing and youthful the gaze appears. This study included a literature review of the features that make the gaze appear attractive. Photographs of models with attractive gazes were examined, and old photographs of patients were compared to recent photographs. The frame ratio was defined by anthropometric measurements of modern portraits of twenty consecutive Miss World winners. The concept was then validated for age and attractiveness across centuries by analysis of modern female photographs and works of art acknowledged for portraying beautiful young and older women in classical paintings. The frame height inversely correlated with attractiveness in modern female portrait photographs. The eye fissure frame ratio of modern idealized female portraits was similar to that of beautiful female portraits idealized by classical artists. In contrast, the eye fissure frames of classical artists' mothers' portraits were significantly wider than those of beautiful younger women. The Frame Concept is a valid artistic tool that provides an understanding of both the aesthetic and aging characteristics of the female periorbital region, enabling the practitioner to plan appropriate aesthetic interventions.

    Large regional differences exist in female participation across regions within Japan. This paper uses two datasets to show that a significant convergence in female participation took place from 1940 to 2010. Historically, urban areas have had low participation, whereas non-urban areas have had high participation. The participation rate rose steadily and significantly in urban areas and, to a lesser extent in non-urban areas, and as a result, regional differences shrank over time. The microdat...

    Falling fertility rates have often been linked to rising female wages. However, over the last 40 years the US total fertility rate has been rather stable while female wages have continued to grow. Over the same period, women's hours spent on housework have declined, but men's have increased. I propose a model in which households are not perfectly specialized, but both men and women contribute to home production. As the gender wage gap narrows, the time allocations of men and women converge, a...

    Changes in our global world have shifted the skill demands from acquisition of structured knowledge to mastery of skills, often referred to as twenty-first century competencies. Given these changes, a sequential explanatory mixed methods study was undertaken to (a) examine predominant instructional methods and technologies used by teacher educators, (b) identify attributes for learning and teaching in the twenty-first century, and (c) develop a pedagogical framework for promoting meaningful usage of advanced technologies. Quantitative and qualitative data were collected via an online survey, personal interviews, and written reflections with science teacher educators and student teachers. Findings indicated that teacher educators do not provide sufficient models for the promotion of reform-based practice via web 2.0 environments, such as Wikis, blogs, social networks, or other cloud technologies. Findings also indicated four attributes for teaching and learning in the twenty-first century: (a) adapting to frequent changes and uncertain situations, (b) collaborating and communicating in decentralized environments, (c) generating data and managing information, and (d) releasing control by encouraging exploration. Guided by social constructivist paradigms and twenty-first century teaching attributes, this study suggests a pedagogical framework for fostering meaningful usage of advanced technologies in science teacher education courses.

    In the adult female, acne is a chronic condition with a substantial negative psychological, social and emotional impact. Based on time of onset, two subtypes of adult female acne are recognized: 'persistent acne' is a continuation of the disease from adolescence, while 'late-onset acne' first presents in adulthood. The morphological characteristics of adult female acne are often distinct from adolescent acne. In adults, inflammatory lesions (particularly papules, pustules and nodules) are generally more prominent on the lower chin, jawline and neck, and comedones are more often closed comedones (micro cysts). Adult acne is mainly mild-to-moderate in severity and may be refractory to treatment. A holistic approach to acne therapy should be taken in adult females, which combines standard treatments with adjunctive therapy and cosmetic use. A number of factors specific to the adult female influence choice of treatment, including the predisposition of older skin to irritation, a possible slow response to treatment, a high likelihood of good adherence, whether of child-bearing age, and the psychosocial impact of the disease. Adherence to therapy should be encouraged through further patient education and a simplified regimen that is tailored to suit the individual patient's needs and lifestyle. This article reviews the specific characteristics of adult female acne, and provides recommendations for acne therapy in this patient group. © 2013 The Authors.

  11. Genital evolution: why are females still understudied?

    Directory of Open Access Journals (Sweden)

    Malin Ah-King

    2014-05-01

    Full Text Available The diversity, variability, and apparent rapid evolution of animal genitalia are a vivid focus of research in evolutionary biology, and studies exploring genitalia have dramatically increased over the past decade. These studies, however, exhibit a strong male bias, which has worsened since 2000, despite the fact that this bias has been explicitly pointed out in the past. Early critics argued that previous investigators too often considered only males and their genitalia, while overlooking female genitalia or physiology. Our analysis of the literature shows that overall this male bias has worsened with time. The degree of bias is not consistent between subdisciplines: studies of the lock-and-key hypothesis have been the most male focused, while studies of cryptic female choice usually consider both sexes. The degree of bias also differed across taxonomic groups, but did not associate with the ease of study of male and female genital characteristics. We argue that the persisting male bias in this field cannot solely be explained by anatomical sex differences influencing accessibility. Rather the bias reflects enduring assumptions about the dominant role of males in sex, and invariant female genitalia. New research highlights how rapidly female genital traits can evolve, and how complex coevolutionary dynamics between males and females can shape genital structures. We argue that understanding genital evolution is hampered by an outdated single-sex bias.

    1999-04-01

    This article addresses heterosexual men's familiarity with the female condom and their attitudes toward this barrier method. Qualitative interviews were conducted with 71 ethnically diverse and heterosexually active men who were recruited in sexually transmitted disease (STD) clinics or through word of mouth in communities with high HIV/STD seroprevalence in New York City during fall 1994 to fall 1995. Only one man reported previous experience with the female condom. The large majority of men had no or limited knowledge of the female condom. Men's reactions to learning about this method ranged from positive to negative, although most men reported willingness to have sex with a partner who wanted to use the female condom. Positive reactions included: endorsement of a woman-controlled condom and her right to use it, the potential for enhancing one's sexual pleasure, and an eagerness to have a new sexual experience. Negative reactions centered on the "strangeness" and "bigness" of the female condom, concerns about prevention efficacy, and concerns about reductions in sexual pleasure. Our findings highlight the need for HIV prevention programs that target heterosexual men and promote the use of the female condom.

    Full Text Available John Orchard1, Trefor James2, Alex Kountouris2, Marc Portus21School of Public Health, University of Sydney, Sydney, Australia; 2Cricket Australia, Melbourne, AustraliaAbstract: This study analyzes injuries occurring prospectively in Australian men’s cricket at the state and national levels over 11 seasons (concluding in season 2008–09. In the last four of these seasons, there was more cricket played, with most of the growth being a new form of the game – Twenty20 cricket. Since the introduction of a regular Twenty20 program, injury incidence rates in each form of cricket have been fairly steady. Because of the short match duration, Twenty20 cricket exhibits a high match injury incidence, expressed as injuries per 10,000 hours of play. Expressed as injuries per days of play, Twenty20 cricket injury rates compare more favorably to other forms of cricket. Domestic level Twenty20 cricket resulted in 145 injuries per 1000 days of play (compared to 219 injuries per 1000 days of domestic one day cricket, and 112 injuries per 1000 days of play in first class domestic cricket. It is therefore recommended that match injury incidence measures be expressed in units of injuries per 1000 days of play. Given the high numbers of injuries which are of gradual onset, seasonal injury incidence rates (which typically range from 15–20 injuries per team per defined ‘season’ are probably a superior incidence measure. Thigh and hamstring strains have become clearly the most common injury in the past two years (greater than four injuries per team per season, perhaps associated with the increased amount of Twenty20 cricket. Injury prevalence rates have risen in conjunction with an increase in the density of the cricket calendar. Annual injury prevalence rates (average proportion of players missing through injury have exceeded 10% in the last three years, with the injury prevalence rates for fast bowlers exceeding 18%.

    The aim of this study was to analyze maxillofacial region fractures during the past 20 years in the Department of Maxillofacial Surgery in Prishtina. We have analyzed the histories of all patients with trauma who were hospitalized in the Department of Maxillofacial Surgery in Prishtina since the opening of the clinic in 1983 through 2005. Narrowing the subject of our research, we concentrated on fractures of the maxillofacial region treated at the Clinic of Maxillofacial Surgery for the period 2001-2005. We have analyzed those fractures and compared them with the period from 1983 to 2005 only when it was reasonable. During this period, 1,945 patients were treated for trauma in the maxillofacial region by the Department of Maxillofacial Surgery. This group included 19.8% females and 80.2% males. The largest age group were those between 20 and 20 years of age. Causes of trauma for both periods were predominantly traffic accidents; however, during the period 2001-2005, interpersonal conflicts were increasingly the cause of fractures. Interpersonal conflict as a cause of maxillofacial trauma has risen in recent years. With this increase the methods of treating fractures in this region are also changing.

    A Corynorhinus townsendii maternity roost located in an abandoned ranch house in central California was monitored for 25 y. Prior to the discovery of the bats in 1987, the house was broken into regularly and disturbance levels were quite high. Upon discovery of the roost, the house was fortified and vandalism was greatly reduced. The number of females and the number of volant young greatly increased during our study and was directly correlated with the decline in vandalism. Bats emerged from the house 43.6 (± 10.9 SD) min after local sunset. Bats emerged later in the evening during spring and fall, when it was warmer, and when it was windier. We also evaluated duration of emergence (47.11 [45.0–49.7] min), and seasonal patterns of re-entry into the roost. Several factors suggested that potential predation, most likely by owls, influenced both the timing and duration of evening emergences.

    Objective: To set up a data bank for residents health condition 20 kilometers within around Qinshan nuclear power station. Methods: Combining with retrospective investigation, the relevant data were acquired from medical certification for resident's death reported by all local disease surveillance. Results: The mortality rate of these residents from 1988 to 1999 was 6.92%. The first course of mortality was diseases of respiratory system, the second of circulatory system, and the third was malignant tumor. The first 5 death causes among all male and female persons were diseases of respiratory system and circulatory system, malignant tumor, injuries and poisoning, diseases of digestive system. The mortality rate for malignant tumor was 121.33/100000 (the standard death rate is : 100.13/100000), and liver cancer was the first death cause, while lung and stomach cancers, the second and the third, respectively. The main death causes in juvenile and youth was leukemia, but liver cancer and lung cancer were the main courses of death in the middle-aged, and in old people, lung and liver cancers. Conclusion: The chronic non-infectious diseases in respiratory system, circulatory system etc, are the major death causes in the residents, the mortality rate for malignant tumor in them is lower than that reported by provincial disease surveillance station

    The objective of this study was to measure intraocular pressure (IOP) in intact, healthy guinea pigs (15 male, 15 female) every 2 h for a 24-h period. First, IOP was measured by using rebound tonometry (RBT). After a 1-min rest period, 0.5% proparacaine ophthalmic solution, a topical anesthetic, was applied to both eyes; 4 min after anesthetic instillation, IOP was measured by using applanation tonometry (APT). The IOP was lower during the light period (0700 to 1900) than during the dark phase (2000 to 0600). The lowest IOP by both RBT and APT (3.68 and 13.37 mm Hg, respectively) occurred at 0700, whereas maximal IOP occurred at 2300 for RBT (8.12 mm Hg) but at 2100 for APT (20.62 mm Hg). No significant differences in IOP between the left and right eyes or between RBT and APT were noted. In addition, daily variations in the IOP of guinea pigs seem to be independent of sex and body weight. The results of this study may be beneficial in the diagnosis and observation of glaucoma in guinea pigs.

    Intrabdominal actinomycosis is difficult to diagnose preoperatively. This chronic infection has a propensity to mimic many other diseases and may present with a wide variety of symptoms. The aim of this study was to evaluate the characteristic clinical features with review of the literature. We retrospectively analyzed 22 patients with intrabdominal actinomycosis between January 2000 and January 2006. There were two men and 20 women with a mean age of 42.8 years (range, 24-69). Twelve patients presented with masses or abdominal pain, whereas 3 patients presented with acute appendicitis. The rate of performing an emergency surgery was 50% due to symptoms of peritonitis. The mean size of tumor was 5.5 cm (range, 2.5-11.0). Sixty percent (n = 12) of female patients had intrauterine device (IUD). The average time to definite diagnosis was 10.6 days. Intrabdominal abdominal actinomycosis must first be suspected in any women with a history of current or recent IUD use who presents abdominal pain. If recognized preoperatively, a limited surgical procedure, may spare the patient from an extensive operation.

    Surgery has been identified as a male-dominated specialty in South Africa and abroad. This study explored how female registrars perceived the impact of gender on their training and practice of surgery. A self-administered questionnaire was used to explore whether females perceived any benefits to training in a male-dominated specialty, their choice of mentors and the challenges that they encountered during surgical training. Thirty-two female registrars participated in the study. The respondents were mainly South African (91%) and enrolled in seven surgical specialties. Twenty-seven (84%) respondents were satisfied with their training and skills development. Twenty-four (75%) respondents had a mentor from the department. Seventeen (53%) respondents perceived having received differential treatment due to their gender and 25 (78.2%) thought that the gender of their mentor did not impact on the quality of the guidance received in surgery. Challenges included physical threats to female respondents from patients and disrespect, emotional threats and defaming statements from male registrars. Additional challenges included time-constraints for family and academic work, poor work-life balance and being treated differently due to their gender. Seventeen (53%) respondents would consider teaching in the Department of Surgery. Generally, females had positive perceptions of their training in Surgery. They expressed concern about finding and maintaining a work-life balance. The gender of their mentor did not impact on the quality of the training but 'bullying' from male peers and selected supervisors occurred. Respondents will continue to recommend the specialty as a satisfying career to young female students.

    A personal best marathon time has been reported as a strong predictor variable for an Ironman race time in recreational female Ironman triathletes. This raises the question whether recreational female Ironman triathletes are similar to recreational female marathoners. We investigated similarities and differences in anthropometry and training between 53 recreational female Ironman triathletes and 46 recreational female marathoners. The association of anthropometric variables and training characteristics with race time was investigated using bi- and multi-variate analysis. The Ironman triathletes were younger (P marathoners. Overall weekly training hours were higher in the Ironman triathletes (P marathoners (P marathon split time for the Ironman triathletes (P = 0.01) and to marathon race time for the marathoners (P = 0.01). To conclude, although personal best marathon time is a strong predictor variable for performance in recreational female Ironman triathletes, there are differences in both anthropometry and training between recreational female Ironman triathletes and recreational female marathoners and different predictor variables for race performance in these two groups of athletes. These findings suggest that recreational female Ironman triathletes are not comparable to recreational female marathoners regarding the association between anthropometric and training characteristics with race time.
