This article is about children who are shared between their parent, households and siblings. They are shared...

Since the 1960s, faculty from diverse fields have banded together under the banner of the medical humanities, a term which unites art, literature, history, anthropology, religious studies, philosophy, and other disciplines. Arguments for the relevance of medical humanities often emphasize contributions that any of these disciplines can make to medical education, whether those involve empathy, professionalism, critical reasoning, or tolerating ambiguity. The authors argue that the constituent disciplines of the medical humanities are not interchangeable parts, but represent different perspectives and methodologies that offer their own distinct contributions to medical training. Efforts to define a role for medical humanities in medical education should pursue two strategies in parallel. On the one hand, advocates of the medical humanities should continue to make the case for the shared contributions that all of the disciplines can make to medical education. But advocates for the medical humanities should also emphasize the valuable contributions of each specific discipline, in terms that medical educators can understand. The authors illustrate this point by delineating contributions of their own discipline, medical history. Historical analysis contributes essential insights to the understanding of disease, therapeutics, and institutions-things that all physicians must know in order to be effective as clinicians, just as they must learn anatomy or pathophysiology. Analogous but different arguments can be made for literature, philosophy, and the other disciplines that constitute the medical humanities. The field of medical humanities will be most successful if it builds on both the shared and the distinct contributions of its disciplines.
Predictive processing models of cognition are promising an elegant way to unite action, perception, and learning. However, in the current formulations, they are species-unspecific and have very little particularly human about them. I propose to examine how, in this framework, humans can be able to massively interact and to build shared worlds that are both material and symbolic.
Full Text Available This paper compares various explanatory concepts of food sharing in humans. In many animal species, parents share food with their offspring, thus investing into the 50% of their own genes present in each child. Even in modern families of industrialised societies, there is a very significant flow of material goods from the parent to the offspring generation. Sharing food between reproductive partners is also easily explainable in evolutionary terms: „food for sex“ as male strategy is observed in some primate species. Sharing within one’s group in small-scale societies can be explained also as consequence of its members being actually rather closely related to each other; this, among others, gives credit to the concept of group selection which gains attention again after having been discarded by classic sociobiology. The ethos of individual and group sharing can quite readily be transferred to larger groups, i.e. a whole nation or, especially in the case of unusually devastating natural disasters, to members of other societies. Food sharing beyond genetic relationship or reproductive interest has been explained as „tit for tat“ and „reciprocal altruism“. Events of give and take, however, are, how the last example demonstrates, quite often non-symmetrical, i.e. one partner shares much more than the other. „Tolerated theft“, a behavioural trait in non-human primate species thought to be a stepping stone for the typical preparedness of humans to share, does not play a big role in traditional societies, which provide an important base to discuss the topic. The Trobriand Islanders, e.g., have a very complex system of sharing. In the years of competitive harvest, their yield of yam is distributed to close relatives, especially to fathers and elder brothers. The donors keep almost nothing for themselves, are however given as well, so that everybody has enough to live. High rank men receive a partly enormous surplus, by which their

To solve the problem of human-robot collaborationwith no communication, we present a model th...
Full Text Available The major goal of the paper was to develop a theoretical framework that conceptualizes the indirect impact on human resource management practice on knowledge sharing in the organization. In the current competitive environment, the ability to use knowledge assets and to continuously renovate it is required for organizational success. Therefore, the field of human resource management should dedicate great effort to understanding how to enhance the knowledge flows within the organization. Theoretical indications were provided about HRM practices that influence the quality and quantity of knowledge sharing within an organization. Further, a conceptual model of relations between HRM practices and factors influencing knowledge sharing within an organization was introduced. It is supposed that HRM practices have direct impacts on personality traits of employees, organizational culture, characteristics of managers, and instruments used for knowledge sharing. Subsequently, these factors have direct effects on the perceived intensity of knowledge sharing. The paper offers 12 testable propositions for the indirect relation between HRM practices and knowledge sharing in the organization. The suggested model could assist future research to examine the influence of HRM practices upon managing knowledge is a more complex way. Via a theoretical contribution to the debate on the influence on HRM practices upon managing knowledge, the study contributes to further research development in this field.

If a society decides to make use of the advantages of technologies that at the same time bear extensive potentials of harm, society has to prevent abuse of these potentials. Physical protection and other security measures inevitably entail a curtailment of personal liberty. The civil rights will not provide sufficient protection against such creeping loss of personal freedom. The high priority of the objects of legal protection in question will make it necessary to specify the civil rights according to conditions if the security measures are to become effective in practice. Weighing the legal merits and the principle of reasonableness will be the main instruments that will pave the way for a camouflaged change of legal concepts and, finally, a factual restriction of civil rights. Any policy of law intended to protect the civil rights therefore will have to clain responsible participation in research activities, technological development, and energy policy. The policy of law has to take care that the criterion of compatibility with the constitution, the weakening or strengthening effect of a technological system on the civil rights, will duly be taken into account in the process of democratic technology steering, and as early as possible.

Recombination generates variation and facilitates evolution. Recombination (or lack thereof) also contributes to human genetic disease. Methods for mapping genes influencing complex genetic diseases via association rely on linkage disequilibrium (LD) in human populations, which is influenced by rates of recombination across the genome. Comparative population genomic analyses of recombination using related primate species can identify factors influencing rates of recombination in humans. Such studies can indicate how variable hotspots for recombination may be both among individuals (or populations) and over evolutionary timescales. Previous studies have suggested that locations of recombination hotspots are not conserved between humans and chimpanzees. We made use of the data sets from recent resequencing projects and applied a Bayesian method for identifying hotspots and estimating recombination rates. We also reanalyzed SNP data sets for regions with known hotspots in humans using samples from the human and chimpanzee. The Bayes factors (BF) of shared recombination hotspots between human and chimpanzee across regions were obtained. Based on the analysis of the aligned regions of human chromosome 21, locations where the two species show evidence of shared recombination hotspots (with high BFs) were identified. Interestingly, previous comparative studies of human and chimpanzee that focused on the known human recombination hotspots within the β-globin and HLA regions did not find overlapping of hotspots. Our results show high BFs of shared hotspots at locations within both regions, and the estimated locations of shared hotspots overlap with the locations of human recombination hotspots obtained from sperm-typing studies.

Our technologies have enabled us to change both the world and our perceptions of the world, as well as to change ourselves and to find new ways to fulfil the human desire for improvement and for having new capacities. The debate around using technology for human enhancement has already raised many ethical concerns, however little research has been done in how human enhancement can affect human communication. The purpose of this paper is to explore whether some human enhancements could change our shared lifeworld so radically that human communication as we know it would not be possible any longer. After exploring the kinds of communication problems we are concerned with as well as mentioning some possible enhancement interventions that could bring about such problems, we will address some of the ethical implications that follow from these potential communication problems. We argue that because of the role that communication plays in human society, this issue deserves attention.
Full Text Available Young children spontaneously share resources with anonymous recipients, but little is known about the specific circumstances that promote or hinder these prosocial tendencies. Children (ages 3-11 received a small (12 or large (30 number of stickers, and were then given the opportunity to share their windfall with either one or multiple anonymous recipients (Dictator Game. Whether a child chose to share or not varied as a function of age, but was uninfluenced by numerical context. Moreover, children's giving was consistent with a proportion-based account, such that children typically donated a similar proportion (but different absolute number of the resources given to them, regardless of whether they originally received a small or large windfall. The proportion of resources donated, however, did vary based on the number of recipients with whom they were allowed to share, such that on average, children shared more when there were more recipients available, particularly when they had more resources, suggesting they take others into consideration when making prosocial decisions. Finally, results indicated that a child's gender also predicted sharing behavior, with males generally sharing more resources than females. Together, findings suggest that the numerical contexts under which children are asked to share, as well as the quantity of resources that they have to share, may interact to promote (or hinder altruistic behaviors throughout childhood.

Proteomic technologies, such as yeast twohybrid, mass spectrometry (MS), protein/ peptide arrays and fluorescence microscopy, yield multi-dimensional data sets, which are often quite large and either not published or published as supplementary information that is not easily searchable. Without a system in place for standardizing and sharing data, it is not fruitful for the biomedical community to contribute these types of data to centralized repositories. Even more difficult is the annotation and display of pertinent information in the context of the corresponding proteins. Wikipedia, an online encyclopedia that anyone can edit, has already proven quite successful1 and can be used as a model for sharing biological data. However, the need for experimental evidence, data standardization and ownership of data creates scientific obstacles.

The petroleum industry in Norway is a high-tech locomotive with spin-offs and ripple effects that affect the entire nation. The oil and gas industry is the country's largest source of income. Thanks to its oil and natural gas, Norway has become a rich country, both in terms of money and knowledge. Oil production on the Norwegian Shelf peaked in the summer of 2000 and is now declining. We do not explore as much as we used to, and the activity level is falling. As a professional body and employer's organization for oil companies and supplier firms, one of OLF's most important tasks is to help ensure that the Norwegian Shelf is an attractive area for investment and activities. The industry needs larger exploration areas and competitive framework conditions. Fiscal changes have been proposed that will make it more profitable for the industry to increase exploration activities, while also making it more economical to extract oil and gas from the smaller fields. Measures must be implemented to stimulate more activity and good exploitation of the oil and gas resources in the years to come. On this basis, OLF has commissioned a report on social perspectives concerning the oil and gas activities. The social perspectives report addresses the significance of the petroleum industry for industrial and welfare development in Norway, exploration areas and access to resources, safety, technology and expertise, as well as environmental challenges and coexistence among marine industries. Values must be created before they can be shared. If we are to ensure a high level of welfare for generations yet to come, it is essential that the oil and gas activities last as long as possible (author) (ml)

The primary objective of this study is to describe human milk sharing practices in the U.S. Specifically, we examine milk sharing social networks, donor compensation, the prevalence of anonymous milk sharing interactions, recipients' concerns about specific milk sharing risks, and lay screening behaviors. Data on human milk sharing practices were collected via an online survey September 2013-March 2014. Chi-square analyses were used to test the association between risk perception and screening practices. A total of 867 (661 donors, 206 recipients) respondents were included in the analyses. Most (96.1%) reported sharing milk face-to-face. Only 10% of respondents reported giving or receiving milk through a non-profit human milk bank, respectively. There were no reports of anonymous purchases of human milk. A small proportion of recipients (4.0%) reported that their infant had a serious medical condition. Screening of prospective donors was common (90.7%) but varied with social relationship and familiarity. Likewise, concern about specific milk sharing risks was varied, and risk perception was significantly associated (P-values = 0.01 or less) with donor screening for all risk variables except diet. Understanding lay perceptions of milk sharing risk and risk reduction strategies that parents are using is an essential first step in developing public health interventions and clinical practices that promote infant safety. © 2015 The Authors.

Humans are inherently mobile creatures. The way we move around our environment has consequences for a wide range of problems, including the design of efficient transportation systems and the planning of urban areas. Here, we gather data about the position in space and time of about 16 000 individuals who uploaded geo-tagged images from locations within the UK to the Flickr photo-sharing website. Inspired by the theory of Lévy flights, which has previously been used to describe the statistical properties of human mobility, we design a machine learning algorithm to infer the probability of finding people in geographical locations and the probability of movement between pairs of locations. Our findings are in general agreement with official figures in the UK and on travel flows between pairs of major cities, suggesting that online data sources may be used to quantify and model large-scale human mobility patterns.

Full Text Available This paper explores whether there is a relationship between humanness and the willingness to share knowledge in Malaysia. Furthermore, the differences between the Malay, Chinese and Indian ethnicities are researched for the presence of humanness and the willingness to share knowledge. Two hundred and fourteen respondents from privately owned companies participated in this research showing that there is a strong relationship between humanness and knowledge sharing. However, the differences between the three ethnicities are small, which is a surprising finding. It can be concluded that people-oriented managers (one of the ways to express humanness are more willing to share knowledge, and differences between ethnicities have no influence in this matter. From these results, it can be recommended to managers and organizations in Malaysia that they pay more attention and be aware of their management style.Stressing the humanness aspects more as they are described could improve the knowledge transfer within companies.

Historical examples of demographic change, in China, Italy, Nigeria, Utah, Easter Island, and elsewhere, together with simple mathematics and biological principles, show that stabilizing world population before it is limited by food supply will be more difficult than is generally appreciated. United Nations population projections are wrong because they assume, in spite of the absence of necessary feedbacks, that all nations will converge rapidly to replacement-level fertility and thereafter remain at that level. Education of women and provision of contraceptives have caused dramatic reductions in fertility, but many groups, including some that are well-educated, maintain high fertility. Small groups with persistent high fertility can grow to supplant low-fertility groups, resulting in continued growth of the total population. The global average fertility rate could rise even if each country's fertility rate is falling. In some low-fertility European countries where deaths exceed births, the population continues to grow because of immigration. Producing more than two offspring is normal for all animal species with stable populations because their populations are limited by resources or predation rather than birth control. It may therefore be appropriate to view the growth of human population as the result not of excess fertility but rather of excess food.

In 1956, on the eve of human space travel Strughold first proposed a simple classification of the present and future stages of manned flight that identified key factors, risks and developmental stages for the evolutionary journey ahead. As we look to optimize the potential of the ISS as a gateway to new destinations, we need a current shared working definitional model of long duration human space flight to help guide our path. Initial search of formal and grey literature augmented by liaison with subject matter experts. Search strategy focused on both the use of term long duration mission and long duration spaceflight, and also broader related current and historical definitions and classification models of spaceflight. The related sea and air travel literature was also subsequently explored with a view to identifying analogous models or classification systems. There are multiple different definitions and classification systems for spaceflight including phase and type of mission, craft and payload and related risk management models. However the frequently used concepts of long duration mission and long duration spaceflight are infrequently operationally defined by authors, and no commonly referenced classical or gold standard definition or model of these terms emerged from the search. The categorization (Cat) system for sailing was found to be of potential analogous utility, with its focus on understanding the need for crew and craft autonomy at various levels of potential adversity and inability to gain outside support or return to a safe location, due to factors of time, distance and location.

Full Text Available The tracking of sentinel health events in humans in order to detect and manage disease risks facing a larger population is a well accepted technique applied to influenza, occupational conditions and emerging infectious diseases. Similarly, animal health professionals routinely track disease events in sentinel animal colonies and sentinel herds. The use of animals as sentinels for human health threats, or of humans as sentinels for animal disease risk, dates back at least to the era when coal miners brought caged canaries into mines to provide early warning of toxic gases. Yet the full potential of linking animal and human health information to provide warning of such ‘shared risks’ from environmental hazards has not been realised. Reasons appear to include the professional segregation of human and animal health communities, the separation of human and animal surveillance data and evidence gaps in the linkages between human and animal responses to environmental health hazards. The ‘One Health initiative’ and growing international collaboration in response to pandemic threats, coupled with development in the fields of informatics and genomics, hold promise for improved sentinel event coordination in order to detect and reduce environmental health threats shared between species.

Data sharing of de-identified individual participant data is being adopted by an increasing number of sponsors of human clinical trials. In addition to standardizing data syntax for shared trial data, semantic integration of various data elements is the focus of several initiatives that define research common data elements. This perspective article, in the first part, compares several data sharing platforms for de-identified clinical research data in terms of their size, policies and supported features. In the second part, we use a case study approach to describe in greater detail one data sharing platform (Data Share from National Institute of Drug Abuse). We present data on the past use of the platform, data formats offered, data de-identification approaches and its use of research common data elements. We conclude with a summary of current and expected future trends that facilitate secondary research use of data from completed human clinical trials.
Your story 'Thousands of nurses leave NHS posts to maintain work-life balance' (online news, 3 March) made me think. Maybe it would be better if employers didn't break the Working Time Directive, making us swap from a 12-hour night shift to a 14-hour day with no day off in-between, or two long days in a row with not enough time to go home, shower, sleep and get ready for work between them.

There are three main approaches about the question of Human Nature. essentialists consider that there exists a permanent Human Nature, shared by every human being. Existentialists consider that there is no such thing as human nature, but inescapable modes of being in the world. A moderate approach would consider that Human Nature can be modified within the limits of anthropological invariants. Transhumanists are conservative in that they think that there is a Human Nature; but they are radical in that they believe that it can (and must) be transcended by bio-technnologies and computer technologies. This project is evaluated as a caricature of suitable human enhancement.

A human-rights-based analysis can be a useful tool for the scientific community and policy makers as they develop codes of conduct, harmonized standards, and national policies for data sharing. The human rights framework provides a shared set of values and norms across borders, defines rights and responsibilities of various actors involved in data sharing, addresses the potential harms as well as the benefits of data sharing, and offers a framework for balancing competing values. The right to enjoy the benefits of scientific progress and its applications offers a particularly helpful lens through which to view data as both a tool of scientific inquiry to which access is vital and as a product of science from which everyone should benefit. © The Author(s) 2015.

Laughter is a pervasive human behavior that most frequently happens in a social context. However, data linking the behavior of laughter with psychological or social outcomes is exceptionally rare. Here, we draw attention to shared laughter as a useful objective marker of relationship well-being. Spontaneously-generated laughs of 71 heterosexual romantic couples were coded from a videorecorded conversation about how the couple first met. Multilevel models revealed that, while controlling for all other laughter present, the proportion of the conversation spent laughing simultaneously with the romantic partner was uniquely positively associated with global evaluations of relationship quality, closeness, and social support. Results are discussed with respect to methodological considerations and theoretical implications for relationships and behavioral research more broadly. PMID:26957946

But what is similar should not be understood as something that is biologically or psychologically or transcendentally shared by all ...
The Shared Socioeconomic Pathways (SSPs) are the new set of alternative futures of societal development that inform global and regional climate change research. They have the potential to foster the integration of socioeconomic scenarios within assessments of future climate-related health impacts. To date, such assessments have primarily superimposed climate scenarios on current socioeconomic conditions only. Until now, the few assessments of future health risks that employed the SSPs have focused on future human exposure-i.e., mainly future population patterns-, neglecting future human vulnerability. This paper first explores the research gaps-mainly linked to the paucity of available projections-that explain such a lack of consideration of human vulnerability under the SSPs. It then highlights the need for projections of socioeconomic variables covering the wide range of determinants of human vulnerability, available at relevant spatial and temporal scales, and accounting for local specificities through sectoral and regional extended versions of the global SSPs. Finally, this paper presents two innovative methods of obtaining and computing such socioeconomic projections under the SSPs-namely the scenario matching approach and an approach based on experts' elicitation and correlation analyses-and applies them to the case of Europe. They offer a variety of possibilities for practical application, producing projections at sub-national level of various drivers of human vulnerability such as demographic and social characteristics, urbanization, state of the environment, infrastructure, health status, and living arrangements. Both the innovative approaches presented in this paper and existing methods-such as the spatial disaggregation of existing projections and the use of sectoral models-show great potential to enhance the availability of relevant projections of determinants of human vulnerability. Assessments of future climate-related health impacts should thus rely

This study analyzes data sharing regarding mitochondrial, Y chromosomal and autosomal polymorphisms in a total of 162 papers on ancient human DNA published between 1988 and 2013. The estimated sharing rate was not far from totality (97.6% ± 2.1%) and substantially higher than observed in other fields of genetic research (evolutionary, medical and forensic genetics). Both a questionnaire-based survey and the examination of Journals' editorial policies suggest that this high sharing rate cannot be simply explained by the need to comply with stakeholders requests. Most data were made available through body text, but the use of primary databases increased in coincidence with the introduction of complete mitochondrial and next-generation sequencing methods. Our study highlights three important aspects. First, our results imply that researchers' awareness of the importance of openness and transparency for scientific progress may complement stakeholders' policies in achieving very high sharing rates. Second, widespread data sharing does not necessarily coincide with a prevalent use of practices which maximize data findability, accessibility, useability and preservation. A detailed look at the different ways in which data are released can be very useful to detect failures to adopt the best sharing modalities and understand how to correct them. Third and finally, the case of human paleogenetics tells us that a widespread awareness of the importance of Open Science may be important to build reliable scientific practices even in the presence of complex experimental challenges.

The existence of genes shared by mammalian sex chromosomes has been predicted on both evolutionary and functional grounds. However, the only experimental evidence for such genes in humans is the cell-surface antigen encoded by loci on the X and Y chromosomes (MIC2X and MIC2Y, respectively), which is recognized by the monoclonal antibody 12E7. Using the bacteriophage λgt11 expression system in Escherichia coli and immunoscreening techniques, the authors have isolated a cDNA clone whose primary product is recognized by 12E7. Southern blot analysis using somatic cell hybrids containing only the human X or Y chromosomes shows that the sequences reacting with the cDNA clone are localized to the sex chromosomes. In addition, the clone hybridizes to DNAs isolated from mouse cells that have been transfected with human DNA and selected for 12E7 expression on the fluorescence-activated cell sorter. The authors conclude that the cDNA clone encodes the 12E7 antigen, which is the primary product of the MIC2 loci. The clone was used to explore sequence homology between MIC2X and MIC2Y; these loci are closely related, if not identical
Currently a fifth of the population die in care homes and most residents are in the final year of life. Spiritual care is recognised as important (The National Institute for Health and Care Excellence [NICE] Quality Standards, Leadership Alliance) yet there is little teaching for care homes' staff in this vital area. Spiritual care is intrinsic in the Gold Standards Framework (GSF) programmes, it is one of the standards for GSF accreditation, yet often health and social care professionals are unaware or unconfident in this area, with a tendency to confuse spirituality with religion. To develop a Spiritual Care course to supplement the range of GSF programmes, especially for care homes, to increase confidence and ability of staff caring for people nearing the end of life. While we need to bring professional expertise to bear in our caring, we must also bring our humanity, our lack of answers and our ability to listen with mindfulness and compassion. Working in collaboration with Staffordshire University, blending academic and practical expertise, we developed a one day workshop and filmed a four-module distance-learning course. Evaluations have shown a broadening of awareness and perspective, increased confidence in assessing and meeting spiritual needs, greater self-care and resilience amongst staff and a more creative interpretation of spiritual care helping to meet the needs of care homes' residents. Early use of this spiritual care workshop and course for care homes' staff has been well received and encouraging. Sharing our common human experience of loss and mortality leads to greater resilience through inner transformation. © 2015, Published by the BMJ Publishing Group Limited.

Organized crime - Trafficking in human beings This thesis deals with the criminal offence of trafficking in human beings under Sec. 168 of the Czech Criminal Code. A trafficking in human being is not a frequent criminal offence but with its consequences belongs to the most dangerous crimes. After the Velvet revolution the relevance of this crime has raised subsequently and therefore the regulation of this crime requires particular attention. It is important to find new ways and improve curren...

The Food and Drug Administration discourages the casual sharing of human milk because of the risk of pathogen transmission. No information is currently available on the prevalence of this practice. The purpose of this mixed-methods observational study is to describe the size and activity of online milk sharing communities. Data for 3 months were extracted from nine public Facebook pages that facilitate the exchange of human milk. The numbers of participants, interactions, and comments were analyzed. We observed 954 individuals participating in milk sharing. The number of interactions per individual ranged from none to 16 (mean, 1.74 ± 1.65). Top reasons that participants requested milk included "lactation problems" (69.4%) and "child health problems" (48.5%). Nearly half of donors were offering 100 ounces or more, which is the minimum to be eligible to donate to nonprofit milk banks. Milk sharing networks in the United States are active, with thousands of individuals participating in the direct exchange of raw human milk. Public health issues include increasing the supply of pasteurized donor milk for fragile infants, increasing breastfeeding support, and helping milk sharing families appropriately manage risks.

Full Text Available While data sharing is becoming increasingly common in quantitative social inquiry, qualitative data are rarely shared. One factor inhibiting data sharing is a concern about human participant protections and privacy. Protecting the confidentiality and safety of research participants is a concern for both quantitative and qualitative researchers, but it raises specific concerns within the epistemic context of qualitative research. Thus, the applicability of emerging protection models from the quantitative realm must be carefully evaluated for application to the qualitative realm. At the same time, qualitative scholars already employ a variety of strategies for human-participant protection implicitly or informally during the research process. In this practice paper, we assess available strategies for protecting human participants and how they can be deployed. We describe a spectrum of possible data management options, such as de-identification and applying access controls, including some already employed by the Qualitative Data Repository (QDR in tandem with its pilot depositors. Throughout the discussion, we consider the tension between modifying data or restricting access to them, and retaining their analytic value. We argue that developing explicit guidelines for sharing qualitative data generated through interaction with humans will allow scholars to address privacy concerns and increase the secondary use of their data.

There are continued claims of attempts to clone humans using nuclear transfer, despite the serious problems that have been encountered in cloning other mammals. It is known that epigenetic and genetic mechanisms are involved in clone failure, but we still do not know exactly how. Human reproductive cloning is unethical, but the production of cells from cloned embryos could offer many potential benefits. So, can human cloning be made safe?

Intensified and extensive data production and data storage are characteristics of contemporary western societies. Health data sharing is increasing with the growth of Information and Communication Technology (ICT) platforms devoted to the collection of personal health and genomic data. However, the sensitive and personal nature of health data poses ethical challenges when data is disclosed and shared even if for scientific research purposes.With this in mind, the Science and Values Working Group of the COST Action CHIP ME 'Citizen's Health through public-private Initiatives: Public health, Market and Ethical perspectives' (IS 1303) identified six core values they considered to be essential for the ethical sharing of health data using ICT platforms. We believe that using this ethical framework will promote respectful scientific practices in order to maintain individuals' trust in research.We use these values to analyse five ICT platforms and explore how emerging data sharing platforms are reconfiguring the data sharing experience from a range of perspectives. We discuss which types of values, rights and responsibilities they entail and enshrine within their philosophy or outlook on what it means to share personal health information. Through this discussion we address issues of the design and the development process of personal health data and patient-oriented infrastructures, as well as new forms of technologically-mediated empowerment.
Human cloning, organ cloning and tissue cloning are various types of cloning that occur at different levels with different methodologies. According to three standards of terminology for an embryo (fertilization through germ cells, development in the uterus and having the potential to produce a human life), tissue cloning and type I organ cloning will not produce an embryo. In contrast, human cloning and type II organ cloning will produce an embryo. Thus, only non-germinal tissue cloning and type I organ cloning are beyond the ethical question and will not change human beings as a species. Using cloned tissues to make new tissues or organs is promising for the future of medicine.

Women today have more life choices than ever before: career, marriage, motherhood, or any combination of the three. Unfortunately little has been done to make up for the competing demands of these roles. Job sharing may be the alternative choice which allows working women to cope with the multiple stressors of having it all--career and family without having to sacrifice their sense of well-being. Nursing administrators stand to benefit from a work schedule alternative which promotes a healthy balance between work and family. Job sharing may offer a solution to the loss of valued staff nurses who require less than full-time employment. In order to compare the general well-being of female nurses who are employed in full-time, casual part-time, and job sharing positions a descriptive correlation study was conducted. One hundred female nurses between the ages of 22 and 40 who have their children living at home with them completed the 18-Item General Well-Being Questionnaire. Additional questions regarding job satisfaction, physical health status, and demographic data were also included. The results of the analyses of variances revealed there were no statistical differences between the general well-being scores of women working full-time, casual part-time, or job sharing. However, crosstabulations showed the job sharing nurses had the highest ratings for job satisfaction and physical health status.

Building on an existing theoretical shared primary care/specialist care framework to (1) develop a unique typology of care for people living with human immunodeficiency virus (HIV) in Ontario, (2) assess sensitivity of the typology by varying typology definitions, and (3) describe characteristics of typology categories. Retrospective population-based observational study from April 1, 2009, to March 31, 2012. A total of 13,480 eligible patients with HIV and receiving publicly funded health care in Ontario. We derived a typology of care by linking patients to usual family physicians and to HIV specialists with five possible patterns of care. Patient and physician characteristics and outpatient visits for HIV-related and non-HIV-related care were used to assess the robustness and characteristics of the typology. Five possible patterns of care were described as low engagement (8.6%), exclusively primary care (52.7%), family physician-dominated comanagement (10.0%), specialist-dominated comanagement (30.5%), and exclusively specialist care (5.2%). Sensitivity analyses demonstrated robustness of typology assignments. Visit patterns varied in ways that conform to typology assignments. We anticipate this typology can be used to assess the impact of care patterns on the quality of primary care for people living with HIV. Copyright © 2015 Elsevier Inc. All rights reserved.

I claim that achieving real human-level artificial intelligence would necessarily imply that most of the tasks that humans perform for pay could be automated. Rather than work toward this goal of automation by building special-purpose systems, I argue for the development of general-purpose, educable systems that can learn and be taught to perform any of the thousands of jobs that humans can perform. Joining others who have made similar proposals, I advocate beginning with a system that has mi...
Full Text Available Maternal well-being is assumed to be associated with well-being of individual family members, optimal parenting practices, and positive developmental outcomes for children. The objective of this study was to examine the interplay between maternal well-being, parent-child activities, and the well-being of 5- to 7-year-old children. In a sample of N = 291 mother-child dyads, maternal life satisfaction, the frequency of shared parent-child activities, as well as children’s self-regulation, prosocial behavior, and receptive vocabulary were assessed using several methods. Data were collected in a special study of the Socio-Economic Panel Study (SOEP, a representative longitudinal survey of private households in Germany. Using structural equation modeling, significant positive direct and indirect relations between maternal life satisfaction, frequency of shared parent-child activities, children’s self-regulation, prosocial behavior, and receptive vocabulary were found. The more satisfied the mother was, the more she shared activities with her child and the more the child acted prosocially. Furthermore, the higher the frequency of shared parent-child activities, the higher the child scored in all three analyzed indicators of children’s well-being: self-regulation, prosocial behavior, and receptive vocabulary. The current study supports the assumption of maternal well-being as the basis of positive parenting practices and child well-being.

Novel beings-intelligent, conscious life-forms sapient in the same way or greater than are human beings-are no longer the preserve of science fiction. Through technologies such as artificial general intelligence, synthetic genomics, gene printing, cognitive enhancement, advanced neuroscience, and more, they are becoming ever more likely and by some definitions may already be emerging. Consideration of the nature of intelligent, conscious novel beings such as those that may result from these technologies requires analysis of the concept of the 'reasonable creature in being' in English law, as well as of the right to life as founded in the European Convention on Human Rights and the attempts to endow human status on animals in recent years. Our exploration of these issues leads us to conclude that there is a strong case to recognize such 'novel' beings as entitled to the same fundamental rights to life, freedom from inhumane treatment, and liberty as we are.

Full Text Available Members of social groups face a trade-off between investing selfish effort for themselves and investing cooperative effort to produce a shared group resource. Many group resources are shared equitably: they may be intrinsically non-excludable public goods, such as vigilance against predators, or so large that there is little cost to sharing, such as cooperatively hunted big game. However, group members' personal resources, such as food hunted individually, may be monopolizable. In such cases, an individual may benefit by investing effort in taking others' personal resources, and in defending one's own resources against others. We use a game theoretic "tug-of-war" model to predict that when such competition over personal resources is possible, players will contribute more towards a group resource, and also obtain higher payoffs from doing so. We test and find support for these predictions in two laboratory economic games with humans, comparing people's investment decisions in games with and without the options to compete over personal resources or invest in a group resource. Our results help explain why people cooperatively contribute to group resources, suggest how a tragedy of the commons may be avoided, and highlight unifying features in the evolution of cooperation and competition in human and non-human societies.

Full Text Available The listed property sector in South Africa has grown to a size which could be considered to be a good representation of the income producing property market in general. Stock market listed property investment funds offer the opportunity to compare indirect property investment to direct property investment, which could bridge the gap between irrational investment behaviour and intrinsic asset values. This study investigates the relationship between listed property share prices and the property values in listed property funds. The share prices are correlated with various factors, such as the accounting ratios of the companies, the financial statements of the companies and general economic variables. The outcome of the study is an explanation of the behaviour of listed property shares, and its relationship to the direct property market and the general economy. This would assist in the explanation of market behaviour and provides the opportunity to more accurately predict portfolio asset values, which might be used in the valuation of individual real estate assets.

Relatively little is known about why some patients are reluctant to engage in a collaborative discussion with physicians about their choices in health care. To explore this issue further, we conducted six focus-group sessions with forty-eight people in the San Francisco Bay Area. In the focus groups, we found that participants voiced a strong desire to engage in shared decision making about treatment options with their physicians. However, several obstacles inhibit those discussions. These include the fact that even relatively affluent and well-educated patients feel compelled to conform to socially sanctioned roles and defer to physicians during clinical consultations; that physicians can be authoritarian; and that the fear of being categorized as "difficult" prevents patients from participating more fully in their own health care. We argue that physicians may not be aware of a need to create a safe environment for open communication to facilitate shared decision making. Rigorous measures of patient engagement, and of the degree to which health care decisions truly reflect patient preferences, are needed to advance shared decision making in clinical practice.
Full Text Available Cooperation and compassion are forms of intelligence. Their lack is an indication of ongoing stress or toxic stress during development that undermined the usual growth of compassion capacities. Though it is hard to face at first awareness, humans in the dominant culture tend to be pretty unintelligent compared to those from societies that existed sustainably for thousands, sometimes tens of thousands, of years. Whereas in sustainable societies everyone must learn to cooperate with earth’s systems to survive and thrive, in the dominant culture this is no longer the case. Now due to technological advances that do not take into account the long-term welfare of earth systems, humans have become “free riders” until these systems collapse from abuse or misuse. The dominant human culture, a “weed species,” has come to devastate planetary ecosystems in a matter of centuries. What do we do to return ourselves to living as earth creatures, as one species among many in community? Humanity needs to restore lost capacities—relational attunement and communal imagination—whose loss occurs primarily in cultures dominated by child-raising practices and ways of thinking that undermine cooperative companionship and a sense of partnership that otherwise develops from the beginning of life. To plant the seeds of cooperation, democracy, and partnership, we need to provide the evolved nest to children, and facilitate the development of ecological attachment to their landscape. This will take efforts at the individual, policy, and institutional levels.

In The Descent of Man, and Selection in Relation to Sex, published in 1871, Charles Darwin wrote: “I fully … subscribe to the judgment of those writers who maintain that of all the differences between man and the lower animals the moral sense or conscience is by far the most important.” I raise the question of whether morality is biologically or culturally determined. The question of whether the moral sense is biologically determined may refer either to the capacity for ethics (i.e., the proclivity to judge human actions as either right or wrong), or to the moral norms accepted by human beings for guiding their actions. I propose that the capacity for ethics is a necessary attribute of human nature, whereas moral codes are products of cultural evolution. Humans have a moral sense because their biological makeup determines the presence of three necessary conditions for ethical behavior: (i) the ability to anticipate the consequences of one's own actions; (ii) the ability to make value judgments; and (iii) the ability to choose between alternative courses of action. Ethical behavior came about in evolution not because it is adaptive in itself but as a necessary consequence of man's eminent intellectual abilities, which are an attribute directly promoted by natural selection. That is, morality evolved as an exaptation, not as an adaptation. Moral codes, however, are outcomes of cultural evolution, which accounts for the diversity of cultural norms among populations and for their evolution through time. PMID:20445091

Current "Internet of Things" concepts point to a future where connected objects gather meaningful information about their environment and share it with other objects and people. In particular, objects embedding Human Machine Interaction (HMI), such as mobile devices and, increasingly, connected vehicles, home appliances, urban interactive infrastructures, etc., may not only be conceived as sources of sensor information, but, through interaction with their users, they can also produce highly valuable context-aware human-generated observations. We believe that the great promise offered by combining and sharing all of the different sources of information available can be realized through the integration of HMI and Semantic Sensor Web technologies. This paper presents a technological framework that harmonizes two of the most influential HMI and Sensor Web initiatives: the W3C's Multimodal Architecture and Interfaces (MMI) and the Open Geospatial Consortium (OGC) Sensor Web Enablement (SWE) with its semantic extension, respectively. Although the proposed framework is general enough to be applied in a variety of connected objects integrating HMI, a particular development is presented for a connected car scenario where drivers' observations about the traffic or their environment are shared across the Semantic Sensor Web. For implementation and evaluation purposes an on-board OSGi (Open Services Gateway Initiative) architecture was built, integrating several available HMI, Sensor Web and Semantic Web technologies. A technical performance test and a conceptual validation of the scenario with potential users are reported, with results suggesting the approach is sound.

Full Text Available Human cooperation is a key driving force behind the evolutionary success of our hominin lineage. At the proximate level, biologists and social scientists have identified other-regarding preferences--such as fairness based on egalitarian motives, and altruism--as likely candidates for fostering large-scale cooperation. A critical question concerns the ontogenetic origins of these constituents of cooperative behavior, as well as whether they emerge independently or in an interrelated fashion. The answer to this question will shed light on the interdisciplinary debate regarding the significance of such preferences for explaining how humans become such cooperative beings. We investigated 15-month-old infants' sensitivity to fairness, and their altruistic behavior, assessed via infants' reactions to a third-party resource distribution task, and via a sharing task. Our results challenge current models of the development of fairness and altruism in two ways. First, in contrast to past work suggesting that fairness and altruism may not emerge until early to mid-childhood, 15-month-old infants are sensitive to fairness and can engage in altruistic sharing. Second, infants' degree of sensitivity to fairness as a third-party observer was related to whether they shared toys altruistically or selfishly, indicating that moral evaluations and prosocial behavior are heavily interconnected from early in development. Our results present the first evidence that the roots of a basic sense of fairness and altruism can be found in infancy, and that these other-regarding preferences develop in a parallel and interwoven fashion. These findings support arguments for an evolutionary basis--most likely in dialectical manner including both biological and cultural mechanisms--of human egalitarianism given the rapidly developing nature of other-regarding preferences and their role in the evolution of human-specific forms of cooperation.

Full Text Available The idea of «human nature» defended by Ortega y Gasset is as original as opposite to what is usually understood. We are making a mistake if the starting point is to conceive Man as one living being among others. Neither science nor philosophy, while remaining in the Eleatic tradition, can give a clear explanation. Science, because if we look at Man, as he is presented to us, it is impossible to distinguish in him materially from spiritually; his body and his psyche. Philosophy, because the concept of «human nature» is an invention of our reason, a fantasy. That nature doesn’t exist because the being of man is so strange and different from other beings that its consistency is just going to be what it never manages to be. Therefore, it is what happens, a journey, a history that is running within a circumstance. This is my life, and that of everyone.

In most animals that vocalize, control of fundamental frequency is a key element for effective communication. In humans, subglottal pressure controls vocal intensity but also influences fundamental frequency during phonation. Given the underlying similarities in the biomechanical mechanisms of vocalization in humans and songbirds, songbirds offer an attractive opportunity to study frequency modulation by pressure. Here, we present a novel technique for dynamic control of subsyringeal pressure in zebra finches. By regulating the opening of a custom-built fast valve connected to the air sac system, we achieved partial or total silencing of specific syllables, and could modify syllabic acoustics through more complex manipulations of air sac pressure. We also observed that more nuanced pressure variations over a limited interval during production of a syllable concomitantly affected the frequency of that syllable segment. These results can be explained in terms of a mathematical model for phonation that incorporates a nonlinear description for the vocal source capable of generating the observed frequency modulations induced by pressure variations. We conclude that the observed interaction between pressure and frequency was a feature of the source, not a result of feedback control. Our results indicate that, beyond regulating phonation or its absence, regulation of pressure is important for control of fundamental frequencies of vocalizations. Thus, although there are separate brainstem pathways for syringeal and respiratory control of song production, both can affect airflow and frequency. We hypothesize that the control of pressure and frequency is combined holistically at higher levels of the vocalization pathways.

COPD is recognized as having a series of comorbidities potentially related to common inflammatory processes. Periodontitis is one of the most common human inflammatory diseases and has previously been associated with COPD in numerous observational studies. As periodontitis and COPD are both chronic, progressive conditions characterized by neutrophilic inflammation with subsequent proteolytic destruction of connective tissue, it has been proposed that they share common pathophysiological processes. The mechanisms proposed to link COPD and periodontitis include mechanical aspiration of oral contents into the respiratory tree, overspill of locally produced inflammatory mediators into the systemic circulation or oral or lung-derived bacteremia activating an acute-phase response and also reactive oxygen species (ROS) and cytokine release by systemic neutrophils at distant sites. Studies of systemic neutrophils in COPD and chronic periodontitis describe altered cellular functions that would predispose to inflammation and tissue destruction both in the lung and in the mouth, again potentially connecting these conditions. However, COPD and periodontitis also share risk factors such as age, chronic tobacco smoke exposure, and social deprivation that are not always considered in observational and interventional studies. Furthermore, studies reporting associations have often utilized differing definitions of both COPD and periodontitis. This article reviews the current available evidence supporting the hypothesis that COPD and inflammatory periodontal disease (periodontitis) could be pathologically associated, including a review of shared inflammatory mechanisms. It highlights the potential limitations of previous studies, in particular, the lack of uniformly applied case definitions for both COPD and periodontitis and poor recognition of shared risk factors. Understanding associations between these conditions may inform why patients with COPD suffer such a burden of comorbid
Full Text Available The hypothesis from which we start our approach is the one according to which the philosophicaldiscourse is a specific way of communicating the reality. The base of the philosophical communication issurprise, doubt, uncertainty, anxiety, all generated by the fundamental interrogations of Kantian origin: Howmuch am I able to know? What do I have to do? What am I allowed to hope? The answers to all thesequestions were set up in philosophical concepts and visions, all of them leading to communication, trying toexpress themselves and make themselves understood. Communicability is the very essence of thephilosophical approach. Actually, communication is a fundamental philosophical attitude as I, in my capacityof human being, live only with the other, in full interaction. On my own I am nothing. Throughout this paperwe find arguments for the idea according to which the philosophical discourse subordinates an art ofgenuinely living and communicating about balance and avoidance of excess, about the ability to assume andovercome, about lucidity and wisdom, about credibility, certainty and truth, about freedom and limitation,about the meaning and value of the human condition.

Large-scale gene expression datasets are providing an increasing understanding of the location of cis-eQTLs in the human genome and their role in disease. However, little is currently known regarding the extent of regulatory site-sharing between genes. This is despite it having potentially wide-ranging implications, from the determination of the way in which genetic variants may shape multiple phenotypes to the understanding of the evolution of human gene order. By first identifying the location of non-redundant cis-eQTLs, we show that regulatory site-sharing is a relatively common phenomenon in the human genome, with over 10% of non-redundant regulatory variants linked to the expression of multiple nearby genes. We show that these shared, local regulatory sites are linked to high levels of chromatin looping between the regulatory sites and their associated genes. In addition, these co-regulated gene modules are found to be strongly conserved across mammalian species, suggesting that shared regulatory sites have played an important role in shaping human gene order. The association of these shared cis-eQTLs with multiple genes means they also appear to be unusually important in understanding the genetics of human phenotypes and pleiotropy, with shared regulatory sites more often linked to multiple human phenotypes than other regulatory variants. This study shows that regulatory site-sharing is likely an underappreciated aspect of gene regulation and has important implications for the understanding of various biological phenomena, including how the two and three dimensional structures of the genome have been shaped and the potential causes of disease pleiotropy outside coding regions.

Historical examples of demographic change, in China, Italy, Nigeria, Utah, the Philippines, and elsewhere, together with simple mathematics and biological principles, show that stabilizing world population before it is limited by food supply will be more difficult than is generally appreciated. United Nations population projections are based on a logical fallacy in that they assume, in spite of the absence of necessary negative feedbacks, that all nations will converge rapidly to replacement-level fertility and thereafter remain at that level. The benign projections that have resulted from this assumption may have hindered efforts to make availability of birth-control a priority in development-aid. Education of women and provision of contraceptives have caused dramatic reductions in fertility, but many groups, including some that are well-educated, maintain high fertility. Small groups with persistent high fertility can grow to supplant low-fertility groups, resulting in continued growth of the total population. The global average fertility rate could rise even if each country's fertility rate is falling. In some low-fertility European countries where deaths exceed births, the population continues to grow because of immigration. Producing more than two offspring is normal for all animal species with stable populations, because their populations are limited by resources or predation rather than birth control. It may therefore be appropriate to view the growth of human population as the result not of excess fertility but rather of excess food. Even if the fertility rate is maintained far in excess of 2, the population cannot grow if food is limiting. Without the agricultural advances of the 20thcentury, world population could not have grown as it did from 1.7 billion in 1900 to 6 billion in 2000. The food supply may be enhanced in the future by genetic engineering and other innovations, but it may be limited by water shortage, climate change, pollution, and energy

Growing evidence supporting the health benefits of human milk, particularly in the preterm population, has led to rising demand for donor human milk in NICUs and pediatric hospitals. There are no previous reports describing the use of unpasteurized shared human milk (USHM) in the hospital setting, but the use of USHM solicited from community donors through social networks appears to be common. Many pediatric hospitals permit inpatients to receive breast milk that has been screened and pasteurized by a human milk banking organization and will provide pasteurized donor human milk (PDHM) only to infants who are preterm or have specific medical conditions. These policies are designed to minimize potential adverse effects from improperly handled or screened donor milk and to target patients who would experience the greatest benefit in health outcomes with donor milk use. We explore the ethical and health implications of 2 cases of medically complex infants who did not meet criteria in our tertiary care hospital for the use of PDHM from a regulated human milk bank and were incidentally found to be using USHM. These cases raise questions about how best to balance the ethical principles of beneficence, nonmaleficence, justice, and patient autonomy in the provision of PDHM, a limited resource. Health care staff should ask about USHM use to provide adequate counseling about the risks and benefits of various feeding options in the context of an infant's medical condition.

Humans share implicit preferences for certain cross-sensory combinations; for example, they consistently associate higher-pitched sounds with lighter colors, smaller size, and spikier shapes. In the condition of synesthesia, people may experience such cross-modal correspondences to a perceptual degree (e.g., literally seeing sounds). So far, no study has addressed the question whether nonhuman animals share cross-modal correspondences as well. To establish the evolutionary origins of cross-modal mappings, we tested whether chimpanzees (Pan troglodytes) also associate higher pitch with higher luminance. Thirty-three humans and six chimpanzees were required to classify black and white squares according to their color while hearing irrelevant background sounds that were either high-pitched or low-pitched. Both species performed better when the background sound was congruent (high-pitched for white, low-pitched for black) than when it was incongruent (low-pitched for white, high-pitched for black). An inherent tendency to pair high pitch with high luminance hence evolved before the human lineage split from that of chimpanzees. Rather than being a culturally learned or a linguistic phenomenon, this mapping constitutes a basic feature of the primate sensory system. PMID:22143791

Many public and private sector projects, such as hydropower dams or mines, trigger forced population displacement but fail to resettle people sustainably and instead cause their impoverishment. Social science research has found that one root cause of such failures and of impoverishment is asset dispossession and the insufficient financing of resettlement. Most governments, however, state that (1) compensation alone is sufficient for restoring the income and livelihood of those displaced, and (2) resources to supplement compensation with additional financing are not available. The author critiques and rejects these positions. He offers a theoretical analysis of the limits and flaws of compensation payments for expropriated assets, and argues that resources are available for supplementing compensation with financial investments for resettlers' development. The sources for supplementary financing are the economic rent (windfall profits) generated by natural resource projects such as hydropower or mining and the regular stream of benefits generated by all projects that require resettlement. Further, the author argues that financial investments in resettlers' welfare are indispensable and that benefit sharing is feasible. Therefore, both should become basic principles of resettlement legislation and practice. In addition to theoretical analysis, the author documents with empirical evidence that some countries (China, Brazil, Canada, Columbia and Japan) already make investments additional to compensation for post-displacement reconstruction. The author sums up his argument in these key points:(1) Compensation alone cannot prevent the impoverishment of resettlers and cannot in itself restore and improve their livelihoods;(2) Additional financing is needed for direct investments in resettlement with development;(3) Compensation levels must be increased;(4) Financing resources are available in most cases for investing in resettlers' development, but allocation of

Full Text Available Abstract Background The corn smut fungus Ustilago maydis is a well-established model system for molecular phytopathology. In addition, it recently became evident that U. maydis and humans share proteins and cellular processes that are not found in the standard fungal model Saccharomyces cerevisiae. This prompted us to do a comparative analysis of the predicted proteome of U. maydis, S. cerevisiae and humans. Results At a cut off at 20% identity over protein length, all three organisms share 1738 proteins, whereas both fungi share only 541 conserved proteins. Despite the evolutionary distance between U. maydis and humans, 777 proteins were shared. When applying a more stringent criterion (≥ 20% identity with a homologue in one organism over at least 50 amino acids and ≥ 10% less in the other organism, we found 681 proteins for the comparison of U. maydis and humans, whereas the both fungi share only 622 fungal specific proteins. Finally, we found that S. cerevisiae and humans shared 312 proteins. In the U. maydis to H. sapiens homology set 454 proteins are functionally classified and 42 proteins are related to serious human diseases. However, a large portion of 222 proteins are of unknown function. Conclusion The fungus U. maydis has a long history of being a model system for understanding DNA recombination and repair, as well as molecular plant pathology. The identification of functionally un-characterized genes that are conserved in humans and U. maydis opens the door for experimental work, which promises new insight in the cell biology of the mammalian cell.

Diminished bite force has been considered a defining feature of modern Homo sapiens, an interpretation inferred from the application of two-dimensional lever mechanics and the relative gracility of the human masticatory musculature and skull. This conclusion has various implications with regard to the evolution of human feeding behaviour. However, human dental anatomy suggests a capacity to withstand high loads and two-dimensional lever models greatly simplify muscle architecture, yielding less accurate results than three-dimensional modelling using multiple lines of action. Here, to our knowledge, in the most comprehensive three-dimensional finite element analysis performed to date for any taxon, we ask whether the traditional view that the bite of H. sapiens is weak and the skull too gracile to sustain high bite forces is supported. We further introduce a new method for reconstructing incomplete fossil material. Our findings show that the human masticatory apparatus is highly efficient, capable of producing a relatively powerful bite using low muscle forces. Thus, relative to other members of the superfamily Hominoidea, humans can achieve relatively high bite forces, while overall stresses are reduced. Our findings resolve apparently discordant lines of evidence, i.e. the presence of teeth well adapted to sustain high loads within a lightweight cranium and mandible. PMID:20554545

Full Text Available Digital traces of activity on social network sites represent a vast source of ecological data with potential connections with individual behavioral and psychological characteristics. The present study investigates the relationship between user-generated textual content shared on Facebook and emotional well-being. Self-report measures of depression, anxiety and stress were collected from 201 adult Facebook users from North Italy. Emotion-related textual indicators, including emoticon use, were extracted form users’ Facebook posts via automated text analysis. Correlation analyses revealed that individuals with higher levels of depression, anxiety expressed negative emotions on Facebook more frequently. In addition, use of emoticons expressing positive emotions correlated negatively with stress level. When comparing age groups, younger users reported higher frequency of both emotion-related words and emoticon use in their posts. Also, the relationship between online emotional expression and self-report emotional well-being was generally stronger in the younger group. Overall, findings support the feasibility and validity of studying individual emotional well-being by means of examination of Facebook profiles. Implications for online screening purposes and future research directions are discussed.

Both stationary 'industrial' and autonomous mobile robots nowadays pervade many workplaces, but human-friendly interaction with them is still very much an experimental subject. One of the reasons for this is that computer and robotic systems are very bad at performing certain tasks well and robust. A prime example is classification of sensor readings: Which part of a 3D depth image is the cup, which the saucer, which the table? These are tasks that humans excel at. To alleviate this problem, we propose a team approah, wherein the robot records sensor data and uses an Augmented-Reality (AR) system to present the data to the user directly in the 3D environment. The user can then perform classification decisions directly on the data by pointing, gestures and speech commands. After the classification has been performed by the user, the robot takes the classified data and matches it to its environment model. As a demonstration of this approach, we present an initial system for creating objects on-the-fly in the environment model. A rotating laser scanner is used to capture a 3D snapshot of the environment. This snapshot is presented to the user as an overlay over his view of the scene. The user classifies unknown objects by pointing at them. The system segments the snapshot according to the user's indications and presents the results of segmentation back to the user, who can then inspect, correct and enhance them interactively. After a satisfying result has been reached, the laser-scanner can take more snapshots from other angles and use the previous segmentation hints to construct a 3D model of the object.

In today's health care, participation is acknowledged as important. However, there is limited research on how relatives of patients at risk of suicide experience their opportunities to participate in care during periods when their close ones are subject to inpatient care. The aim of this study was to describe the phenomenon of participation, as experienced by relatives of persons who are subject to inpatient psychiatric care due to a risk of suicide. The study was conducted through a reflective lifeworld research (RLR) approach, based on phenomenological philosophy. Eight relatives of patients receiving care from professionals in a psychiatric specialist health care context in Sweden participated in phenomenon-oriented interviews. Data were analysed to elucidate a meaning structure of the phenomenon. The findings show that the phenomenon of participation was more associated with patients' recovery processes than with the caring process, and means "being actively involved in a process in which the person regains the desire to live". The meaning of participation is further described by its meaning constituents: struggling for being able to be present for the person at risk of suicide, being able to share everyday life, and nurturing sources for vitality. These insights into the meaning of participation highlight the importance of allowing supportive relatives to be a part of the patient's life, while the person is cared for in an inpatient hospital setting. Thus, participation enables relatives to be acknowledged as resourceful human beings in the patient's recovery process, and thereby facilitates a sense of being able to manage and share life itself together with the person. This means that mental health nurses need to recognize individual variations of relatives' participation processes, and take on the responsibility of acknowledging relatives' lifeworlds.
Full Text Available The recent developments of the Euro crisis reveal the lack of clear or coherent thinking on the part of both the Eurozone finance ministers and the European Commission. The crisis in Cyprus is partly the consequence of decisions made on private sector involvement in the previous Greek bailout, and other such examples may be made. It is time, therefore, to look reality in the face and strengthen the structures of the EMU. The article is devoted to what has been done and what must still be done to make the European banking system more robust and less permeable to crises, and to preserve the single financial market. It looks at the initiatives of both the European Commission and the European Council to complete the EMU by creating a banking union, the doubts on the wisdom of entrusting banking oversight to the ECB, the organization of the ECB’s new tasks, the continuing absence of facilities for the recovery or liquidation of banks, as well as for a Euro-wide deposit insurance, the need for some form of risk-sharing in order to stabilise the economy, and thus the recourse to a common budget and the possibility of joint debt for the Eurozone.

The centrality of communicating in human life means that communication difficulties are experienced at a deeply personal level and have significant implications for identity. Intervention methods may interact positively or negatively with these experiences. This paper explores this intersection in the case of stuttering, suggesting that some intervention styles may dovetail unhelpfully with the "mainstream" prizing of normalcy. In particular, most "western" societies offer a performance-oriented milieu which prizes efficiency, immediacy and competitiveness, diverting energy from the equally important work of understanding and integrating difference. Given that a person who stutters speaks fluently and with a stutter, stuttering can lean toward a complex view of disability identity-being both able and disabled. This split repertoire invites psychologically costly efforts at being "un-disabled". Interventions which amplify this tendency can contribute to an alienation from self amid strivings for normalcy.

Full Text Available Neuropeptide Y (NPY plays a role in a variety of basic physiological functions and has also been implicated in regulating cognition, including learning and memory. A decrease in neocortical NPY has been reported for Alzheimer’s disease, schizophrenia, bipolar disorder, and depression, potentially contributing to associated cognitive deficits. The goal of the present analysis was to examine variation in neocortical NPY-immunoreactive axon and varicosity density among haplorhine primates (monkeys, apes, and humans. Stereologic methods were used to measure the ratios of NPY-expressing axon length density to total neuron density (ALv/Nv and NPY-immunoreactive varicosity density to neuron density (Vv/Nv, as well as the mean varicosity spacing in neocortical areas 10, 24, 44, and 22 (Tpt of humans, African great apes, New World monkeys, and Old World monkeys. Humans and great apes showed increased cortical NPY innervation relative to monkey species for ALv/Nv and Vv/Nv. Furthermore, humans and great apes displayed a conserved pattern of varicosity spacing across cortical areas and layers, with no differences between cortical layers or among cortical areas. These phylogenetic differences may be related to shared life history variables and may reflect specific cognitive abilities.

A shared-control scheme for a powered wheelchair is presented. The wheelchair can be operated by a wheelchair driver using a joystick, or directed by a sensor system, or control can be combined between them. The wheelchair system can modify direction depending on the local environment. Sharing the control allows a disabled wheelchair driver to drive safely and efficiently. The controller automatically establishes the control gains for the sensor system and the human driver by calculating a self-reliance factor for the wheelchair driver. The sensor system can influence the motion of the wheelchair to compensate for some deficiency in a disabled driver. Practical tests validate the proposed techniques and designs.

Full Text Available This investigation discusses the question how an older generation should transfer to or share their own worldview with a younger generation. For various reasons this has become a problem today. One is the inability of some of the old guard to share their perspective on and way of life with the youth. Another factor is that the Christian youth of today is strongly influenced by contemporary cultural tendencies, often incompatible with a biblically based worldview. The question how a worldview should be transferred as well as how it should be received is of equal and crucial importance to ensure that an age-old, valuable tradition does not become the living worldview of the dead and the dead worldview of the living. Therefore, answers to the following questions should be found: (1 What is the essence of such a worldview to be shared? (2 Why should it be shared? (3 How should it not be done? (4 What are the prerequisites for effective sharing? (5 What are the typical characteristics of the young receivers, the group today called Generation Y, Me, or the Millennials (those born between about 1980–2000? (6 How should this group of emerging adults receive such a heritage? The abstract above mentions the six questions to be answered by both the older and younger generation when they seriously try to share a Christian worldview. What follows is an attempt to provide answers to these problems.

Full Text Available The aim of this research was to analyze the process of implementation and management of the Shared Services Center for Human Resources, in a multinational company in the context of mergers and acquisitions. The company analyzed was called here Alpha, and is one of the largest food companies in the country that was born of a merger between Beta and Delta in 2008. The CSC may constitute a tool for strategic management of HR that allows repositioning of the role of the area in order to be more strategic at corporate level and more profitable at the operating level. The research was based on a descriptive and exploratory study of qualitative approach. Among the results, there is the fact that shared services were strategic to support, standardize and ensure the expansion of the company. The challenges found were associated with the development of a culture of service and the relationship with users and the definition of HR activities scope. The following management procedures include the adequacy of wage differences between employees, the career path limitation and the need to attract and retain talent and international expansion.

Amblyopia is a common visual disorder that results in a spatial acuity deficit in the affected eye. Orthodox treatment is to occlude the unaffected eye for lengthy periods, largely determined by the severity of the visual deficit at diagnosis. Although this treatment is not without its problems (poor compliance, potential to reduce binocular function etc.) it is effective in many children with moderate to severe amblyopia. Diagnosis and initiation of treatment early in life are thought to be critical to the success of this form of therapy. Occlusion is rarely undertaken in older children (over 10 years old) as the visual benefits are considered to be marginal. Therefore, in subjects where occlusion is not effective or those missed by mass screening programmes there is no alternative therapy available later in life. More recently, burgeoning evidence has begun to reveal previously unrecognised levels of residual neural plasticity in the adult brain and scientists have developed new genetic, pharmacological and behavioural interventions to activate these latent mechanisms in order to harness their potential for visual recovery. Prominent amongst these is the concept of perceptual learning - the fact that repeatedly practicing a challenging visual task leads to substantial and enduring improvements in visual performance over time. In the normal visual system the improvements are highly specific to the attributes of the trained stimulus. However, in the amblyopic visual system learned improvements have been shown to generalize to novel tasks. In this paper we ask whether amblyopic deficits can be reduced in adulthood and explore the pattern of transfer of learned improvements. We also show that developing training protocols that target the deficit in stereo acuity allows the recovery of normal stereo function even in adulthood. This information will help guide further development of learning-based interventions in this clinical group. PMID:21870913

Full Text Available Abstract Hominin evolution is characterized by adaptive solutions often rooted in behavioral and cognitive changes. If balancing selection had an important and long-lasting impact on the evolution of these traits, it can be hypothesized that genes associated with them should carry an excess of shared polymorphisms (trans- SNPs across recent Homo species. In this study, we investigate the role of balancing selection in human evolution using available exomes from modern (Homo sapiens and archaic humans (H. neanderthalensis and Denisovan for an excess of trans-SNP in two gene sets: one associated with the immune system (IMMS and another one with behavioral system (BEHS. We identified a significant excess of trans-SNPs in IMMS (N=547, of which six of these located within genes previously associated with schizophrenia. No excess of trans-SNPs was found in BEHS, but five genes in this system harbor potential signals for balancing selection and are associated with psychiatric or neurodevelopmental disorders. Our approach evidenced recent Homo trans-SNPs that have been previously implicated in psychiatric diseases such as schizophrenia, suggesting that a genetic repertoire common to the immune and behavioral systems could have been maintained by balancing selection starting before the split between archaic and modern humans.

Purpose The aim of this study was to determine Turkish women's knowledge, attitudes, and behaviors on wet-nursing, milk sharing, and human milk banking in a primary care setting located in a semi-rural area. Description Donated human milk is a feasible option for feeding infants and children. Currently, there is a debate on the topic starts with the preparations to launch a human milk bank in a large city in Turkey. Several previous papers reported women's opinions in large hospital based studies. Little is known about women's views and practice on donated human milk in the rural areas of Turkey. Assessment The study sample was recruited among married women aged 15-49 years who had given birth within the past 5 years and who were in a family health center for any reason in Honaz, Denizli, Turkey. A total of 240 women were included in the study. The data were collected by questionnaire created by the researchers and consisting of two parts: sociodemographic characteristics, and women's knowledge, attitudes, and behaviors on wet-nursing, milk sharing and human milk banking. Results Thirty women (12.5%) had had a wet-nurse; 20 women (8.7%) wet-nursed babies before; and 17 (7.2%) of the women's children had a wet-nurse. If necessary, 80.9 and 78.3% were willing to accept to do wet-nursing and milk sharing, respectively. 150 (62.5%) heard of human milk banks; 55 (22.9%) approved of the establishment of milk banks. However, only 46 women (19.1%) were willing to donate to the bank. Possibility of marriages between milk siblings (76.8%) was the main reason for not considering the donation. Women's education was another factor affecting their opinion on breast milk sharing and donation to human milk banks. Less educated women were sympathetic to milk sharing (p = 0.02), however, more educated mothers had a propensity to donate to milk banks (p = 0.02). Conclusion Wet-nursing decreased over the years in Turkey, but still an ongoing small child feeding method

The planetary boundaries framework proposes precautionary quantitative global limits to the anthropogenic perturbation of crucial Earth system processes. In this way, it marks out a planetary 'safe operating space' for human activities. However, decisions regarding resource use and emissions are mostly made at much smaller scales, mostly by (sub-)national and regional governments, businesses, and other local actors. To operationalize the planetary boundaries, they need to be translated into and aligned with targets that are relevant at these smaller scales. In this paper, we develop a framework that addresses the three dimension of bridging across scales: biophysical, socio-economic and ethical, to provide a consistent universally applicable approach for translating the planetary boundaries into national level context-specific and fair shares of the safe operating space. We discuss our findings in the context of previous studies and their implications for future analyses and policymaking. In this way, we help link the planetary boundaries framework to widely- applied operational and policy concepts for more robust strong sustainability decision-making.

Human milk sharing between peers is a common and growing practice. Although human milk has been unequivocally established as the ideal food source for infants, much stigma surrounds the practice of human milk sharing. Furthermore, there is little research examining peer-to-peer human milk sharing. Research Aim: We used the liberation health social work model to examine the experiences of mothers who have received donated human milk from a peer. Research questions were as follows: (a) What challenges do recipient mothers experience in peer-to-peer human milk sharing? (b) What supports do recipient mothers identify in peer-to-peer human milk sharing? Researchers conducted in-depth interviews with mothers ( N = 20) in the United States and Canada who were recipients of peer-to-peer human milk sharing. Researchers independently reviewed transcripts and completed open, axial, and selective coding. The authors discussed conflicts in theme identification until agreement was reached. Challenges to peer-to-peer human milk sharing were (a) substantial effort required to secure human milk; (b) institutional barriers; (c) milk bank specific barriers; and (d) lack of societal awareness and acceptance of human milk sharing. Facilitators included (a) informed decision making and transparency and (b) support from healthcare professionals. Despite risks and barriers, participants continued to pursue peer-to-peer human milk sharing. Informed by a liberation health framework, healthcare professionals-rather than universally discouraging human milk sharing between peers-should facilitate open dialogue with parents about the pros and cons of this practice and about screening recommendations to promote safety and mitigate risk.

Prior work has established that children and adults distinguish moral norms (e.g., hitting is wrong) from conventional norms (e.g., wearing pajamas to school is wrong). Specifically, moral norms are generally perceived as universal across time and space, similar to objective facts. We examined preschoolers' and adults' perceptions of moral beliefs alongside facts and opinions by asking whether only one person could be right in the case of disagreements. We also compared perceptions of widely shared moral beliefs (e.g., whether it is better to pull someone's hair or share with someone) and controversial moral beliefs (e.g., whether it is better to help someone with a project or make cookies for someone). In Studies 1 and 2, preschoolers and adults were more likely to judge that only one person could be right in the case of widely shared versus controversial moral beliefs, treating the former as more objective or fact-like. Children were also more likely than adults to say that only one person could be right in a moral disagreement. Study 2 additionally revealed that adults were more likely than children to report preferring individuals who shared their controversial moral beliefs. Study 3 replicated these patterns using a different sample of widely shared beliefs (e.g., whether it is okay to mock a poor classmate) and controversial moral beliefs (e.g., whether it is okay to tell small, prosocial lies). While some aspects of moral cognition may depend on abundant social learning and cognitive development, the perception that disagreements about widely shared moral beliefs have only one right answer while disagreements about controversial moral beliefs do not emerges relatively early. We discuss implications for moral learning and social preferences. Copyright © 2016 Elsevier B.V. All rights reserved.

Although the value of health is universally agreed upon, its definition is not. Both the WHO and the UN define health in terms of well-being. They advocate a globally shared responsibility that all of us - states, international organizations, pharmaceutical corporations, civil society, and individuals - bear for the health (that is, the well-being) of the world's population. In this paper I argue that this current well-being conception of health is troublesome. Its problem resides precisely in the fact that the well-being conception of health, as an all-encompassing label, does not properly distinguish between the different realities of health and the different demands of justice, which arise in each case. In addressing responsibilities related to the right to health, we need to work with a more differentiated vocabulary, which can account for these different realities. A crucial distinction to bear in mind, for the purposes of moral deliberation and the crafting of political and legal institutions, is the difference between basic and non-basic health needs. This distinction is crucial because we have presumably more stringent obligations and rights in relation to human needs that are basic, as they justify stronger moral claims, than those grounded on non-basic human needs. It is important to keep this moral distinction in mind because many of the world's problems regarding the right to health relate to basic health needs. By conflating these needs with less essential ones, we risk confusing different types of moral claims and weakening the overall case for establishing duties regarding the right to health. There is, therefore, a practical need to reevaluate the current normative conception of health so that it distinguishes, within the broad scope of well-being, between what is basic and what is not. My aim here is to shed light onto this distinction and to show the need for this differentiation. I do so, first, by providing, on the basis of David Miller

Soul caregivers often hesitate to be vulnerable in their pastoral practices. Jesus, however, embraced his vulnerabilities as a human to redeem humanity even though he was the Son of God. This paper first explores the dynamics of shame and power that make soul caregivers reluctant to accept their vulnerabilities and then describes the contributions of sharing caregiver's vulnerabilities in a soul care practice. This article argues that being vulnerable allows a soul caregiver to imitate Jesus by sharing in the client's common humanity, initiating an authentic relationship between the client and the soul caregiver; it is also a practice of humility, inviting God's cure in soul care. This study proposes the necessity of embracing vulnerability in soul care ministry, instead of hiding it.

The iambic-trochaic law describes humans' tendency to form trochaic groups over sequences varying in pitch or intensity (i.e., the loudest or highest sounds mark group beginnings), and iambic groups over sequences varying in duration (i.e., the longest sounds mark group endings). The extent to which these perceptual biases are shared by humans and nonhuman animals is yet unclear. In Experiment 1, we trained rats to discriminate pitch-alternating sequences of tones from sequences randomly varying in pitch. In Experiment 2, rats were trained to discriminate duration-alternating sequences of tones from sequences randomly varying in duration. We found that nonhuman animals group sequences based on pitch variations as trochees, but they do not group sequences varying in duration as iambs. Importantly, humans grouped the same stimuli following the principles of the iambic-trochaic law (Exp. 3). These results suggest the early emergence of the trochaic rhythmic grouping bias based on pitch, possibly relying on perceptual abilities shared by humans and other mammals, whereas the iambic rhythmic grouping bias based on duration might depend on language experience.

The feeling of being moved has only received marginal attention by emotion research during the last decades. Recently, an emotion framework termed kama muta has been introduced giving a first overview and suggesting that being moved is a positive cultural-dependent feeling typically accompanied by tears, piloerection, and a warm feeling in the chest (Seibt, Schubert, Zickfeld & Fiske, 2015). The present article tries to give a first insight into the effects of kama muta. Based on relational m...
From cells to societies, several general principles arise again and again that facilitate cooperation and suppress conflict. In this study, I describe three general principles of cooperation and how they operate across systems including human sharing, cooperation in animal and insect societies and the massively large-scale cooperation that occurs in our multicellular bodies. The first principle is that of Walk Away: that cooperation is enhanced when individuals can leave uncooperative partners. The second principle is that resource sharing is often based on the need of the recipient (i.e., need-based transfers) rather than on strict account-keeping. And the last principle is that effective scaling up of cooperation requires increasingly sophisticated and costly cheater suppression mechanisms. By comparing how these principles operate across systems, we can better understand the constraints on cooperation. This can facilitate the discovery of novel ways to enhance cooperation and suppress cheating in its many forms, from social exploitation to cancer.
This conference was organized a month after the publication by the International Energy Agency (IEA) of the 2007 World Energy Outlook (WEO) study. The energy situation at that time was marked by the repercussions on the environment and on the security of supplies in relation with the accelerated development of China and India. This document gathers the transparencies of the two presentations given at this conference. The first presentation by Fatih Birol, Chief Economist at the IEA, is entitled 'World Energy Outlook 2007: China and India Insights'. It presents the Cooperation with China's National Development and Reform Commission (NDRC) and Energy Research Institute (ERI), and with India's Energy and Resources Institute (TERI) for the establishment of energy scenarios. Then the different scenarios are reviewed: Reference Scenario, Alternative Policy Scenario and 450 Stabilisation Case, High Growth Scenario (China/India). Finally, a full global update of projections (all scenarios) is presented and the impact of China and India on global economy, energy markets and environment is analyzed. The conclusions are as follows: - Global energy system is on an increasingly unsustainable path; - China and India are transforming the global energy system by their sheer size; - Challenge for all countries is to achieve transition to a more secure, lower carbon energy system; - New policies now under consideration would make a major contribution; - Next 10 years are critical (The pace of capacity additions will be most rapid, Technology will be 'locked-in' for decades, Growing tightness in oil and gas markets); - Challenge is global so solutions must be global. The second presentation by Jean-Charles Hourcade (CIRED) is entitled 'The WEO 2007 A few comments about the Emerging Giants... and us'. The presentation focusses on 4 points: - What implications of higher growth in the Asian Giants on the world economy through higher pressure on energy resources; - Economic questions
Full Text Available In the current paper I will argue that the notion of affordances offers an alternative to theory of mind (ToM approaches in studying social engagement in general and in explaining social engagement in autism spectrum disorder (ASD specifically. Affordances are the possibilities for action offered by the environment. In contrast to ToM approaches, the concept of affordances implies the complementarity of person and environment and rejects the dualism of mind and behaviour. In line with the Gibsonian idea that a child must eventually perceive the affordances of the environment for others as well for herself in order to become socialized, I will hypothesize that individuals with ASD often do not perceive the same affordances in the environment as other people do and have difficulties perceiving others' affordances. This can lead to a disruption of interpersonal behaviours. I will further argue that the methods for studying social engagement should be adapted if we want to take interaction into account.

It is important to know whether the laws or phenomena in statistical physics for natural systems with non-adaptive agents still hold for social human systems with adaptive agents, because this implies whether it is possible to study or understand social human systems by using statistical physics originating from natural systems. For this purpose, we review the role of human adaptability in four kinds of specific human behaviors, namely, normal behavior, herd behavior, contrarian behavior, and hedge behavior. The approach is based on controlled experiments in the framework of market-directed resource-allocation games. The role of the controlled experiments could be at least two-fold: adopting the real human decision-making process so that the system under consideration could reflect the performance of genuine human beings; making it possible to obtain macroscopic physical properties of a human system by tuning a particular factor of the system, thus directly revealing cause and effect. As a result, both computer simulations and theoretical analyses help to show a few counterparts of some laws or phenomena in statistical physics for social human systems: two-phase phenomena or phase transitions, entropy-related phenomena, and a non-equilibrium steady state. This review highlights the role of human adaptability in these counterparts, and makes it possible to study or understand some particular social human systems by means of statistical physics coming from natural systems.

After last year’s analysis regarding the European Union’s commitment to fight against the human beings trafficking, we have considered to further explore the human beings trafficking approach in the European Court of Human Rights case-law, the most developped regional jurisdiction on human rights. Surprisingly, the European Convention for the Protection of Human Rights and Fundamental Freedoms does not make an express reference to the human beings trafficking. However, we have to bear in mind...

This philosophical enquiry considers the impact of a global world view and technology on the meaning of being human. The global vision increases our awareness of the common bond between all humans, while technology tends to separate us from an understanding of ourselves as human persons. We review some advances in connecting as community within our world, and many examples of technological changes. This review is not exhaustive. The focus is to understand enough changes to think through the possibility of healthcare professionals becoming cyborgs, human-machine units that are subsequently neither human and nor machine. It is seen that human technology interfaces are a different way of interacting but do not change what it is to be human in our rational capacities of providing meaningful speech and freely chosen actions. In the highly technical environment of the ICU, expert nurses work in harmony with both the technical equipment and the patient. We used Heidegger to consider the nature of equipment, and Descartes to explore unique human capacities. Aristotle, Wallace, Sokolowski, and Clarke provide a summary of humanity as substantial and relational. © 2015 John Wiley & Sons Ltd.

Exposure to many different chemicals during pregnancy through maternal circulation is possible. Transplacental transfer of xenobiotics can be demonstrated using human placental perfusion. Also, placental perfusion can give information about the placental kinetics as well as metabolism and accumulation in the placenta because it retains the tissue structure and function. Although human placental perfusion has been used extensively to study the transplacental transfer of drugs, the information on food and environmental carcinogens is much more limited. This review deals with the foetal exposure to food and environmental carcinogens in human beings. In particular, human transplacental transfer of the food carcinogens such as acrylamide, glycidamide and nitrosodimethylamine are in focus. Because these carcinogens are genotoxic, the functional capacity of human placenta to induce DNA adduct formation or metabolize these above mentioned CYP2E1 substrates is of interest in this context. © 2011 The Authors.

Land has traditionally been spared to protect biodiversity; however, this approach has not succeeded by itself and requires a complementary strategy in human-dominated landscapes: land-sharing. Human-wildlife conflicts are rampant in a land-sharing context where wildlife co-occur with crops or livestock, but whose resulting interactions adversely affect the wellbeing of land owners, ultimately impeding coexistence. Therefore, true land-sharing only works if coexistence is also considered an end goal. We reviewed the literature on land-sharing and found that conflicts have not yet found their way into the land-sharing/sparing framework, with wildlife and humans co-occurring without coexisting in a dynamic process. To successfully implement a land-sharing approach, we must first acknowledge our failure to integrate the body of work on human-wildlife conflicts into the framework and work to implement multidisciplinary approaches from the ecological, economic, and sociological sciences to overcome and prevent conflicts. We suggest the use of Conflict Transformation by means of the Levels of Conflict Model to perceive both visible and deep-rooted causes of conflicts as opportunities to create problem-solving dynamics in affected socio-ecological landscapes. Reconciling farming and nature is possible by aiming for a transition to landscapes that truly share space by virtue of coexistence.
Full Text Available Acquisition of bipedality is a hallmark of human evolution. How bipedality evolved from great ape-like locomotor behaviors, however, is still highly debated. This is mainly because it is difficult to infer locomotor function, and even more so locomotor kinematics, from fossil hominin long bones. Structure-function relationships are complex, as long bone morphology reflects phyletic history, developmental programs, and loading history during an individual's lifetime. Here we discriminate between these factors by investigating the morphology of long bones in fetal and neonate great apes and humans, before the onset of locomotion.Comparative morphometric analysis of the femoral diaphysis indicates that its morphology reflects phyletic relationships between hominoid taxa to a greater extent than taxon-specific locomotor adaptations. Diaphyseal morphology in humans and chimpanzees exhibits several shared-derived features, despite substantial differences in locomotor adaptations. Orangutan and gorilla morphologies are largely similar, and likely represent the primitive hominoid state.These findings are compatible with two possible evolutionary scenarios. Diaphyseal morphology may reflect retained adaptive traits of ancestral taxa, hence human-chimpanzee shared-derived features may be indicative of the locomotor behavior of our last common ancestor. Alternatively, diaphyseal morphology might reflect evolution by genetic drift (neutral evolution rather than selection, and might thus be more informative about phyletic relationships between taxa than about locomotor adaptations. Both scenarios are consistent with the hypothesis that knuckle-walking in chimpanzees and gorillas resulted from convergent evolution, and that the evolution of human bipedality is unrelated to extant great ape locomotor specializations.

We consider the problem of establishing entangled states of optimal singlet fraction and negativity between two remote parties for every use of a noisy quantum channel and trace-preserving local operations and classical communication (LOCC) under the assumption that the parties do not share prior correlations. We show that for a family of quantum channels in every finite dimension d ≥3 , one-shot optimal singlet fraction and entanglement negativity are attained only with appropriate nonmaximally entangled states. A consequence of our results is that the ordering of entangled states in all finite dimensions may not be preserved under trace-preserving LOCC.

Value at Risk (VaR) is used as an indicator to measure the risks contained in a firm. With the uprising development of VaR theory and computational techniques, the VaR is nowadays adopted by banks and reported in annual reports. Since the method to calculate VaR is questioned, and the reported VaR can not be thoroughly audited, this paper attempts to find the relationship between the reported VaR and the volatility of share price for UK listed banks. This paper reviews literature about VaR an...

Full Text Available The overall goal of our study was to compare the proteins found in the saliva proteomes of three mammals: human, mouse and rat. Our first objective was to compare two human proteomes with very different analysis depths. The 89 shared proteins in this comparison apparently represent a core of highly-expressed human salivary proteins. Of the proteins unique to each proteome, one-half to 2/3 lack signal peptides and probably are contaminants instead of less highly-represented salivary proteins. We recently published the first rodent saliva proteomes with saliva collected from the genome mouse (C57BL/6 and the genome rat (BN/SsNHsd/Mcwi. Our second objective was to compare the proteins in the human proteome with those we identified in the genome mouse and rat to determine those common to all three mammals, as well as the specialized rodent subset. We also identified proteins unique to each of the three mammals, because differences in the secreted protein constitutions can provide clues to differences in the evolutionary adaptation of the secretions in the three different mammals.

Background Current US colorectal cancer screening guidelines that call for shared decision making regarding the choice among several recommended screening options are difficult to implement. Multi-criteria decision analysis (MCDA) is an established methodology well suited for supporting shared decision making. Our study goal was to determine if a streamlined form of MCDA using rank order based judgments can accurately assess patients’ colorectal cancer screening priorities. Methods We converted priorities for four decision criteria and three sub-criteria regarding colorectal cancer screening obtained from 484 average risk patients using the Analytic Hierarchy Process (AHP) in a prior study into rank order-based priorities using rank order centroids. We compared the two sets of priorities using Spearman rank correlation and non-parametric Bland-Altman limits of agreement analysis. We assessed the differential impact of using the rank order-based versus the AHP-based priorities on the results of a full MCDA comparing three currently recommended colorectal cancer screening strategies. Generalizability of the results was assessed using Monte Carlo simulation. Results Correlations between the two sets of priorities for the seven criteria ranged from 0.55 to 0.92. The proportions of absolute differences between rank order-based and AHP-based priorities that were more than ± 0.15 ranged from 1% to 16%. Differences in the full MCDA results were minimal and the relative rankings of the three screening options were identical more than 88% of the time. The Monte Carlo simulation results were similar. Conclusion Rank order-based MCDA could be a simple, practical way to guide individual decisions and assess population decision priorities regarding colorectal cancer screening strategies. Additional research is warranted to further explore the use of these methods for promoting shared decision making. PMID:24300851

Small-scale research projects involving human subjects have been identified as being effective in developing critical appraisal skills in undergraduate students. In deciding whether to grant ethical approval to such projects, university research ethics committees must weigh the benefits of the research against the risk of harm or discomfort to the participants. As the learning objectives associated with student research can be met without the need for human subjects, the benefit associated with training new healthcare professionals cannot, in itself, justify such risks. The outputs of research must be shared with the wider scientific community if it is to influence future practice. Our survey of 19 UK universities indicates that undergraduate dissertations associated with the disciplines of medicine, dentistry and pharmacy are not routinely retained in their library catalogues, thus closing a major avenue to the dissemination of their findings. If such research is unlikely to be published in a peer-reviewed journal, presented at a conference, or otherwise made available to other researchers, then the risks of harm, discomfort or inconvenience to participants are unlikely to be offset by societal benefits. Ethics committees should be satisfied that undergraduate research will be funnelled into further research that is likely to inform clinical practice before granting ethical approval.

Are sensory estimates formed centrally in the brain and then shared between perceptual and motor pathways or is centrally represented sensory activity decoded independently to drive awareness and action? Questions about the brain's information flow pose a challenge because systems-level estimates of environmental signals are only accessible indirectly as behavior. Assessing whether sensory estimates are shared between perceptual and motor circuits requires comparing perceptual reports with motor behavior arising from the same sensory activity. Extrastriate visual cortex both mediates the perception of visual motion and provides the visual inputs for behaviors such as smooth pursuit eye movements. Pursuit has been a valuable testing ground for theories of sensory information processing because the neural circuits and physiological response properties of motion-responsive cortical areas are well studied, sensory estimates of visual motion signals are formed quickly, and the initiation of pursuit is closely coupled to sensory estimates of target motion. Here, we analyzed variability in visually driven smooth pursuit and perceptual reports of target direction and speed in human subjects while we manipulated the signal-to-noise level of motion estimates. Comparable levels of variability throughout viewing time and across conditions provide evidence for shared noise sources in the perception and action pathways arising from a common sensory estimate. We found that conditions that create poor, low-gain pursuit create a discrepancy between the precision of perception and that of pursuit. Differences in pursuit gain arising from differences in optic flow strength in the stimulus reconcile much of the controversy on this topic.

It makes strategic and business sense for payers and providers to collaborate on how to take substantial cost out of the healthcare delivery system. Acting independently, neither medical groups, hospitals nor health plans have the optimal mix of resources and incentives to significantly reduce costs. Payers have core assets such as marketing, claims data, claims processing, reimbursement systems and capital. It would be cost prohibitive for all but the largest providers to develop these capabilities in order to compete directly with insurers. Likewise, medical groups and hospitals are positioned to foster financial interdependence among providers and coordinate the continuum of patient illnesses and care settings. Payers and providers should commit to reasonable clinical and cost goals, and share resources to minimize expenses and financial risks. It is in the interest of payers to work closely with providers on risk-management strategies because insurers need synergy with ACOs to remain cost competitive. It is in the interest of ACOs to work collaboratively with payers early on to develop reasonable and effective performance benchmarks. Hence, it is essential to have payer interoperability and data sharing integrated in an ACO model.

Full Text Available Abstract Background Glutaminyl cyclase (QC forms the pyroglutamyl residue at the amino terminus of numerous secretory peptides and proteins. We previously proposed the mammalian QC has some features in common with zinc aminopeptidases. We now have generated a structural model for human QC based on the aminopeptidase fold (pdb code 1AMP and mutated the apparent active site residues to assess their role in QC catalysis. Results The structural model proposed here for human QC, deposited in the protein databank as 1MOI, is supported by a variety of fold prediction programs, by the circular dichroism spectrum, and by the presence of the disulfide. Mutagenesis of the six active site residues present in both 1AMP and QC reveal essential roles for the two histidines (140 and 330, QC numbering and the two glutamates (201 and 202, while the two aspartates (159 and 248 appear to play no catalytic role. ICP-MS analysis shows less than stoichiometric zinc (0.3:1 in the purified enzyme. Conclusions We conclude that human pituitary glutaminyl cyclase and bacterial zinc aminopeptidase share a common fold and active site residues. In contrast to the aminopeptidase, however, QC does not appear to require zinc for enzymatic activity.

Researchers have used drones to track wildlife populations, monitor forest fires, map glaciers, and measure air pollution but have only begun to consider how to use these unmanned aerial vehicles to study human beings. The potential use of drones to study public gatherings or other human activities raises novel issues of privacy, confidentiality, and consent, which this article explores in depth. It argues that drone research could fall into several different categories: non-human subjects research (HSR), exempt HSR, or non-exempt HSR. In the case of non-exempt HSR, it will be difficult for institutional review boards to approve studies unless they are designed so that informed consent can be waived. Whether drone research is non-HSR, exempt HSR, or non-exempt HSR, it is important for investigators to consult communities which could be affected by the research.

To the best of our knowledge, the genetic foundations that guide human brain development have not changed fundamentally during the past 50,000 years. However, because of their cognitive potential, humans have changed the world tremendously in the past centuries. They have invented technical devices, institutions that regulate cooperation and competition, and symbol systems, such as script and mathematics, that serve as reasoning tools. The exceptional learning ability of humans allows newborns to adapt to the world they are born into; however, there are tremendous individual differences in learning ability among humans that become obvious in school at the latest. Cognitive psychology has developed models of memory and information processing that attempt to explain how humans learn (general perspective), while the variation among individuals (differential perspective) has been the focus of psychometric intelligence research. Although both lines of research have been proceeding independently, they increasingly converge, as both investigate the concepts of working memory and knowledge construction. This review begins with presenting state-of-the-art research on human information processing and its potential in academic learning. Then, a brief overview of the history of psychometric intelligence research is combined with presenting recent work on the role of intelligence in modern societies and on the nature-nurture debate. Finally, promising approaches to integrating the general and differential perspective will be discussed in the conclusion of this review.

The well-being of non-human primates in captivity is of joint concern to scientists, veterinarians, colony managers, caretakers, and researchers working with non-human primates in biomedical research. With increased regulatory, accreditation, and research focus on optimizing the use of social housing for laboratory primates, as well as the advent of techniques to assess indices of chronic stress and related measures of well-being, there is no better time to present the most current advances in the field of non-human primate behavioral management. The collective body of research presented here was inspired in part by a 2014 symposium entitled, "Chronic Hormones and Demographic Variables: Center-Wide Studies on Non-Human Primate Well-Being" held at the American Society of Primatologists' 37th Annual Meeting in Decatur, GA. By aiming to target readership with scientific and/or management oversight of captive primate behavioral management programs, this special issue provides badly-needed guidance for implementing social housing programs in a research environment and leverages collaboration across multiple facilities to address key components of behavioral management, explore refinements in how well-being can be measured, and identify the interrelationships between varying indices.

Full Text Available What does make the ground of the authentic works of music art crossing the centuries and what does move the human soul any time and anywhere? Which is the support of music art – generally speaking – beyond its aesthetic dimension? How could we explain and understand, in a better and in a more efficient way, the powerful influence of musical artistic creation upon the human well-being? These are merely part of the interrogations challenging our interest in finding and revealing the profound link between ethical values, music art and human health (in its integrality. The purpose of this essay is to emphasize the foundation of human equilibrium considering the offer of the harmony carried by music art, exploring the significance of a nucleus-concept of the Greek philosophers that has been acknowledged as kalokagatheia – the self-fulfilled cultivation of body and soul, as a micro-cosmos living within the macro-cosmos. In terms of a philosophical hermeneutics of art, we reach to disclose part of the salutogenic function of music art concerning the human well-being in nowadays.

Mother's milk provides protection from serious and costly morbidity for very-low-birth-weight infants (nosocomial infection, and necrotizing enterocolitis. However, NICU and maternity nurses may be hesitant to encourage mothers to initiate lactation because of a reluctance to make mothers feel guilty or coerced. This article reviews the evidence for the health outcomes of mothers' milk feeding in very-low-birth-weight infants and provides examples of ways to share this science with mothers so that they can make an informed feeding decision.

Discussions of the possible future of Human factors/ergonomics (HFE) usually take the past for granted in the sense that the future of HFE is assumed to be more of the same. This paper argues that the nature of work in the early 2010s is so different from the nature of work when HFE was formulated 60-70 years ago that a critical reassessment of the basis for HFE is needed. If HFE should be a systems discipline, it should be a soft systems rather than a hard systems discipline. It is not enough for HFE to seek to improve performance and well-being through systems design, since any change to the work environment in principle alters the very basis for the change.

"European" identities may be politonymic, toponymic, ethnomyic or linguonymic (Bromley 1984). Each dimension may affect whether migrant minorities are treated as "European", and influence their schooling, integration and rights. Treatment and terminology vary in different states and periods of migration. However, the position for immigrated minorities is that they are still largely seen as workers rather than human beings with equal rights. Lack of success in schools is blamed on the migrants themselves rather than the educational system. This construction of migrants as being deficient is parallel to educational practice which falls within a UN definition of linguistic genocide, and contributes to mis-education. If current efforts in international bodies to codify educational linguistic human rights were to lead to greater support for minorities, this could assist in a redefinition of national identities and a reduction of racism and conflict.

Given the challenge of a high proportion of older employees who retire early from work we analyse associations of indicators of a poor psychosocial quality of work with intended premature departure from work in a large sample of older male and female employees in 10 European countries. Baseline data from the 'Survey of Health, Ageing and Retirement in Europe' (SHARE) were obtained from 3523 men and 3318 women in 10 European countries. Data on intended early retirement, four measures of well-being (self-rated health, depressive symptoms, general symptom load, and quality of life), and quality of work (effort-reward imbalance; low control at work) were obtained from structured interviews and questionnaires. Country-specific and total samples are analysed, using logistic regression analysis. Poor quality of work is significantly associated with intended early retirement. After adjustment for well-being odds ratios (OR) of effort-reward imbalance [OR 1.72 (1.43-2.08)] and low control at work [OR 1.51 (1.27-1.80)] on intended early retirement are observed. Poor quality of work and reduced well-being are independently associated with the intention to retire from work. The consistent association of a poor psychosocial quality of work with intended early retirement among older employees across all European countries under study calls for improved investments into better quality of work, in particular increased control and an appropriate balance between efforts spent and rewards received at work.
This article analyzes three USAID education strategy documents (1998, 2005, and 2011) as well as USAID's requests for proposals for three projects to assess how teachers are represented. The main findings indicate that USAID education strategy documents a) treat teachers as human capital, a human resource input, rather than as human beings and b)…

Bike-sharing has become a popular green transportation choice in many cities around the world. There has been a rapid expansion of bike-sharing schemes in developing countries at recent time. However, many of those were launched without the support of adequate scientific research and hence failed to create the expected demand. Given the increasingly significant urban transportation challenges in developing countries, such as congestion and air pollution caused by the continuously growing priv...
In a liberal-democratic system, there is no possibility of a criminal liability charge without a minimum of freedom. Nevertheless, since a long time ago and, nowadays, with the advancement of science in the human genome, understanding it as a closed system--farm theory--is intended to demonstrate that the genome is a destination, thus criminal liability will be void, giving rise to security measures.

We performed an evaluation of models, techniques, and applicability to the clinical setting of natural orifice surgery (mainly natural orifice transluminal endoscopic surgery [NOTES]) primarily in general surgery procedures. NOTES has attracted much attention recently for its potential to establish a completely alternative approach to the traditional surgical procedures performed entirely through a natural orifice. Beyond the potentially scar-free surgery and abolishment of dermal incision-related complications, the safety and efficacy of this new surgical technology must be evaluated. Studies were identified by searching MEDLINE, EMBASE, Cochrane Library, and Entrez PubMed from 2007 to February 2011. Most of the references were identified from 2009 to 2010. There were limitations as far as the population that was evaluated (only human beings, no cadavers or animals) was concerned, but there were no limitations concerning the level of evidence of the studies that were evaluated. The studies that were deemed applicable for our review were published mainly from 2007 to 2010 (see Methods section). All the evaluated studies were conducted only in human beings. We studied the most common referred in the literature orifices such as vaginal, oral, gastric, esophageal, anal, or urethral. The optimal access route and method could not be established because of the different nature of each procedure. We mainly studied procedures in the field of general surgery such as cholecystectomy, intestinal cancers, renal cancers, appendectomy, mediastinoscopy, and peritoneoscopy. All procedures were feasible and most of them had an uneventful postoperative course. A number of technical problems were encountered, especially as far as pure NOTES procedures are concerned, which makes the need of developing new endoscopic instruments, to facilitate each approach, undeniable. NOTES is still in the early stages of development and more robust technologies will be needed to achieve reliable

The human being is a complex matter and many believe that just trying to understand life and what it means to be human is a futile undertaking. We believe that we have to try to understand life and get a grip on the many faces of life, because it can be of great value to us to learn to recognize the fundamental principles of how life is lived to the fullest. Learning to recognize the good and evil forces of life helps us to make use of the good ones. To be human is to balance between hundreds of extremes. Sometimes we have to avoid these extremes, but at other times it seems we should pursue them, to better understand life. With our roots in medicine, we believe in the importance of love for better health. The secret of the heart is when reason and feelings meet and we become whole. Where reason is balanced perfectly by feelings and where mind and body come together in perfect unity, a whole new quality emerges, a quality that is neither feeling nor reason, but something deeper and more complete. In this paper, we outline only enough biology to clarify what the fundamental inner conflicts are about. The insight into these conflicts gives us the key to a great deal of the problems of life. To imagine pleasures greater than sensual pleasures seems impossible to most people. What could such a joy possibly be? But somewhere deep in life exists the finest sweetness, the greatest quality in life, the pure joy of being alive that emerges when we are fully present and life is in balance. This deep joy of life is what we call experiencing the meaning of life.

In 1999, Tesarik and Greco reported that they could predict the developmental potential of human zygotes from a single static evaluation of their pronuclei. This was based on the distribution and number of specific nuclear organelles - the nucleoli. Recent studies in mice show that nucleoli play a key role in parental genome restructuring after fertilization, and that interfering with this process may lead to developmental failure. These studies thus support the Tesarik-Greco evaluation as a potentially useful method for selecting high-quality embryos in human assisted reproductive technologies. In this opinion article we discuss recent evidence linking nucleoli to parental genome reprogramming, and ask whether nucleoli can mirror or be used as representative markers of embryonic parameters such as chromosome content or DNA fragmentation.

Full Text Available After last year’s analysis regarding the European Union’s commitment to fight against the human beings trafficking, we have considered to further explore the human beings trafficking approach in the European Court of Human Rights case-law, the most developped regional jurisdiction on human rights. Surprisingly, the European Convention for the Protection of Human Rights and Fundamental Freedoms does not make an express reference to the human beings trafficking. However, we have to bear in mind that the Convention is a living instrument, its interpretation being made in the light of the present-day conditions. Thus, taking into consideration the global threat of this phenomenon, it is more obvious than ever that the Convention could not neglect this issue.

Japan's Silver Human Resource Center (SHRC) program provides part-time, paid employment to retirement-aged men and women. We studied 393 new program participants and examined whether part-time work influenced their well-being or "ikigai." The participants were divided into those who had worked in SHRC-provided jobs in the preceding year, and those who had not. Gender-stratified regression models were fitted to determine whether SHRC employment was associated with increased well-being. For men, actively working at a SHRC job was associated with greater well-being, compared to inactive members. And men with SHRC jobs and previous volunteering experience had the greatest increase in well-being. Women SHRC job holders did not experience increased well-being at the year's end. The study concludes that there is justification for exploring the usefulness of a similar program for American retirees who desire post-retirement part-time work.

Recent industrial developments in autonomous systems, or agents, which assume that humans and the agents share the same space or even work in close proximity, open for new challenges in robotics, especially in motion planning and control. In these settings, the control system should be able to provide these agents a reliable path following control when they are working in a group or in collaboration with one or several humans in complex and dynamic environments. In such scenarios, these agents are not only moving to reach their goals, i.e., locations, they are also aware of the movements of other entities to find a collision-free path. Thus, this paper proposes a dependable, i.e., safe, reliable and effective, path planning algorithm for a group of agents that share their working space with humans. Firstly, the method employs the Theta * algorithm to initialize the paths from a starting point to a goal for a set of agents. As Theta * algorithm is computationally heavy, it only reruns when there is a significant change of the environment. To deal with the movements of the agents, a static flow field along the configured path is defined. This field is used by the agents to navigate and reach their goals even if the planned trajectories are changed. Secondly, a dipole field is calculated to avoid the collision of agents with other agents and human subjects. In this approach, each agent is assumed to be a source of a magnetic dipole field in which the magnetic moment is aligned with the moving direction of the agent. The magnetic dipole-dipole interactions between these agents generate repulsive forces to help them to avoid collision. The effectiveness of the proposed approach has been evaluated with extensive simulations. The results show that the static flow field is able to drive agents to the goals with a small number of requirements to update the path of agents. Meanwhile, the dipole flow field plays an important role to prevent collisions. The combination of

Lacking a coordinated effort in utilizing data and tracking program outcomes, one agency developed a Quality Management (QM) division to facilitate and manage more effective data use. To support this process, the agency sought to develop a collective, agency-wide understanding and investment in improving and measuring client outcomes. Similarly, the agency also focused efforts on creating a culture of transparency and accountability, with goals of improving service, increasing agency integrity, meeting regulatory compliance, and engaging in effective risk management. Operationalizing the QM initiative involved developing procedures, systems, and guidelines that would facilitate the generation of reliable and accurate data that could be used to inform program change and decision-making. This case study describes this agency's experience in successfully creating and implementing a QM initiative aimed at engaging in greater knowledge sharing. Copyright © Taylor & Francis Group, LLC

Recombination events induce significant genetic changes, and this process can result in virus genetic diversity or in the generation of novel pathogenicity. We discovered a new recombinant feline leukemia virus (FeLV) gag gene harboring an unrelated insertion, termed the X region, which was derived from Felis catus endogenous gammaretrovirus 4 (FcERV-gamma4). The identified FcERV-gamma4 proviruses have lost their coding capabilities, but some can express their viral RNA in feline tissues. Although the X-region-carrying recombinant FeLVs appeared to be replication-defective viruses, they were detected in 6.4% of tested FeLV-infected cats. All isolated recombinant FeLV clones commonly incorporated a middle part of the FcERV-gamma4 5'-leader region as an X region. Surprisingly, a sequence corresponding to the portion contained in all X regions is also present in at least 13 endogenous retroviruses (ERVs) observed in the cat, human, primate, and pig genomes. We termed this shared genetic feature the commonly shared (CS) sequence. Despite our phylogenetic analysis indicating that all CS-sequence-carrying ERVs are classified as gammaretroviruses, no obvious closeness was revealed among these ERVs. However, the Shannon entropy in the CS sequence was lower than that in other parts of the provirus genome. Notably, the CS sequence of human endogenous retrovirus T had 73.8% similarity with that of FcERV-gamma4, and specific signals were detected in the human genome by Southern blot analysis using a probe for the FcERV-gamma4 CS sequence. Our results provide an interesting evolutionary history for CS-sequence circulation among several distinct ancestral viruses and a novel recombined virus over a prolonged period. IMPORTANCE Recombination among ERVs or modern viral genomes causes a rapid evolution of retroviruses, and this phenomenon can result in the serious situation of viral disease reemergence. We identified a novel recombinant FeLV gag gene that contains an unrelated
The egg-sharing model for human therapeutic cloning research: managing donor selection criteria, the proportion of shared oocytes allocated to research, and amount of financial subsidy given to the donor.
Heng, Boon Chin; Tong, Guo Qing; Stojkovic, Miodrag
Recent advances in human therapeutic cloning made by Hwang and colleagues have opened up new avenues of therapy for various human diseases. However, the major bottleneck of this new technology is the severe shortage of human donor oocytes. Egg-sharing in return for subsidized fertility treatment has been suggested as an ethically justifiable and practical solution to overcome the shortage of donor oocytes for therapeutic cloning. Because the utilization of shared oocytes in therapeutic cloning research does not result in any therapeutic benefit to a second party, this would necessitate a different management strategy compared to their use for the assisted conception of infertile women who are unable to produce any oocytes of their own. It is proposed that the pool of prospective egg-sharers in therapeutic cloning research be limited only to younger women (below 30 years of age) with indications for either male partner sub-fertility or tubal blockage. With regards to the proportion of the shared gametes being allocated to research, a threshold number of retrieved oocytes should be set that if not exceeded, would result in the patient being automatically removed from the egg-sharing scheme. Any excess supernumerary oocyte above this threshold number can be contributed to science, and allocation should be done in a randomized manner. Perhaps, a total of 10 retrieved oocytes from the patient may be considered a suitable threshold, since the chances of conception are unlikely to be impaired. With regards to the amount of subsidy being given to the patient, it is suggested that the proportion of financial subsidy should be equal to the proportion of the patient's oocytes being allocated to research. No doubt, the promise of future therapeutic benefit may be offered to the patient instead of financial subsidy. However, this is ethically controversial because therapeutic cloning has not yet been demonstrated to be a viable model of clinical therapy and any promises made to

In moving into a new kind of world, nurses are encouraged to look ahead and be innovative by transcending to new ways of using nursing knowledge while embracing a new worldview. "We need to recognize that we're going to have to use our imagination more and more" (Rogers, 1994). On that note, the author in this paper explicates Rogers' science of unitary human beings in a creative way relating it to painting. In addition, the author also explores works derived from Rogers' science such as Butcher's (1993) and Cowling's (1997), which are here discussed in light of an artwork. A painting is presented with the unpredictability, creativity, and the "dance of color and light" (Butcher, 1993) is appreciated through comprehending essence, pandimensionality, and wholeness. © The Author(s) 2015.
Full Text Available In 2018, the editors of the Portuguese Journal of Behavioral and Social Research (PJBSR continue to favor the publication of original articles of investigation and revision in the areas of social and behavioral sciences. The PJBSR continues to promote thinking, questioning the changes in society, their realities, and rethinking their problems, encouraging a reflection among their readers. The number 1 of the fourth volume of the PJBSR adds four original articles and one review article. Although this issue of the PJBSR addresses different contents, there is evidence of a focus on the study of positive psychological variables and their relation to human well-being, whether it is operationalized as physical or mental health, studied in the context of institutionalization or in the context of the work, evaluated at the level of the subjective perception of well-being or the level of the conception of death with dignity.
Full Text Available The current study explored how physical attractiveness affects food sharing by studying payment preferences for hypothetical romantic dinner dates (a hypothetical mating market. We analyzed payment preferences, self-rated attractiveness, and rated attractiveness for hypothetical dates in 416 participants. We hypothesized that (1 men would be more likely to prefer to pay than would women, (2 attractive individuals of both sexes would be less willing to pay, and (3 preferences to enter an exchange would be influenced by the attractiveness of prospective partners such that (3a men would prefer to pay for attractive women, and (3b women would prefer to be paid for by attractive men. All hypotheses were supported by our results. Individuals with higher self-rated attractiveness were more likely to prefer that their date would pay for the meal, and we found clear sex differences in how the attractiveness of potential dates affected payment preferences. Male participants preferred to pay for dates that had higher facial attractiveness, while female participants preferred that attractive men would pay. Individuals show condition dependent financial preferences consistent with the provisioning hypothesis in this mating market that are adaptive to evaluations of their own quality and that of prospective partners.

The aim of this study was to describe 1 the number of clinical trials submitted to the Brazilian Health Surveillance Agency (Agência Nacional de Vigilância Sanitária, Anvisa from 2007 to 2012 and the number of human-subject research projects approved by research ethics committees (RECs and the National Research Ethics Committee (Comissão Nacional de Ética em Pesquisa, CONEP in Brazil from 2007 to 2011 and 2 the diseases most frequently studied in Brazilian states in clinical trials approved in the country from 2009 to 2012, based on information from an Anvisa databank. Two databases were used: 1 the National Information System on Research Ethics Involving Human Beings (Sistema Nacional de Informação Sobre Ética em Pesquisa envolvendo Seres Humanos, SISNEP and 2 Anvisa's Clinical Research Control System (Sistema de Controle de Pesquisa Clínica, SCPC. Data from the SCPC indicated an increase of 32.7% in the number of clinical trials submitted to Anvisa, and data from the SISNEP showed an increase of 69.9% in those approved by RECs and CONEP (from 18 160 in 2007 to 30 860 in 2011. Type 2 diabetes (26.0% and breast cancer (20.5%-related to the main causes of mortality in Brazil-were the two most frequently studied diseases. The so-called “neglected diseases,” such as dengue fever, were among the least studied diseases in approved clinical trials, despite their significant impact on social, economic, and health indicators in Brazil. Overall, the data indicated 1 a clear trend toward more research involving human beings in Brazil, 2 good correspondence between diseases most studied in clinical trials approved by Anvisa and the main causes of death in Brazil, and 3 a low level of attention to neglected diseases, an issue that should be considered in setting future research priorities, given their socioeconomic and health effects.

A hierarchy of human activities is derived by analyzing automobile driving in general terms. A structural description leads to a block diagram and a time-sharing computer analogy. The range of applicability of existing mathematical models is considered with respect to the hierarchy of human activities in actual complex tasks. Other mathematical tools so far not often applied to man machine systems are also discussed. The mathematical descriptions at least briefly considered here include utility, estimation, control, queueing, and fuzzy set theory as well as artificial intelligence techniques. Some thoughts are given as to how these methods might be integrated and how further work might be pursued.
Full Text Available Recent studies have provided evidence that young children already engage in sharing behavior. The underlying social‐cognitive mechanisms, however, are still under debate. In particular, it is unclear whether or not young children’s sharing is motivated by an appreciation of others’ wealth. Manipulating the material needs of recipients in a sharing task (Experiment 1 and a resource allocation task (Experiment 2, we show that 5‐ but not 3‐year‐old children share more with poor than wealthy individuals. The 3-year-old children even showed a tendency to behave less selfishly towards the rich, yet not the poor recipient. This suggests that very early instances of sharing behavior are not motivated by a consideration of others’ material needs. Moreover, the results show that 5-year-old children were rather inclined to give more to the poor individual than distributing the resources equally, demonstrating that their wish to support the poor overruled the otherwise very prominent inclination to share resources equally. This indicates that charity has strong developmental roots in preschool children.
Full text: One of the main conclusions from the IAEA’s HRD Conference in 2014 was that people and organisations in the global nuclear industry could cooperate more in sharing information and efforts. This was an inspiring conclusion, and there seemed an especially great opportunity for such sharing of information and efforts related to the attraction, recruitment, development and retention of people within the nuclear workforce. Founding members include people from the IAEA, WNA, WANO, EDF and OPG amongst others, the global working group for Human Resource matters aimed at “Building and Sustaining a Competent Nuclear Workforce” was established. This global working group is free to join and is open to anyone concerned with Building and Sustaining a Competent NuclearWorkforce. The objectives of the group are to share useful information, find others with similar objectives to cooperate with, ask questions, share opinions and crucially to avoid unnecessary duplication of efforts. The group already has 160 members from more than 15 countries and is currently hosted as a group on the LinkedIn website. The vision for the group is that it will become an invaluable resource for people across the world in the nuclear industry for sharing information and efforts. (author

The New Partnership for Africa's Development (NEPAD) is a pledge by African leaders to eradicate poverty and to promote sustainable growth and development. NEPAD is a 'new framework of interaction with the rest of the world, including the industrialised countries and multilateral organizations.' The agenda is based on regional priorities and development plans and its implementation relies on African ownership and management. As a UN system organisation, the IAEA strongly supports the priorities identified in the Millennium Declaration and the New Partnership for Africa's Development. As a technical agency, the IAEA shares its recognized core competencies and technical expertise in support of NEPAD goals. Efforts aim at strengthening institutional capacity building in nuclear sciences and technology and promoting the sustainable application of nuclear techniques for social and economic development. The IAEA has a membership of 34 African countries. The Agency supports them under its technical cooperation programme through provision of expertise, training opportunities and equipment in priority areas identified by the countries themselves. For many African Member States, meeting basic human needs through the implementation of poverty alleviation strategies remains the top priority on the agenda for national development plans and international cooperation programmes. In the context of sustainable development, special attention is being paid to enlarging the contribution of isotopes and nuclear techniques in major areas of economic and social significance and to promoting regional cooperation in nuclear science and technology related fields. As a partner in development, the Agency has promoted and undertaken programmes to support African countries' efforts to address priority development issues particularly in the areas of health care, food and agriculture and water resources development. The IAEA technical cooperation mechanism includes support to the African Regional
The concept of human dignity is examined in terms of the religious belief that man is created in God's image and from the Kantian viewpoint that man's autonomy gives special value to our species. The theory of psychic determinism and the prospect of genetic engineering of humans are seen as attacks on self determination. Five additional attributes that make humans "special" are explored: conceptual thought, the capacity for technology, our range of emotions, "Lamarckian" environmental genetics, and the freedom to change and modify ourselves.

Full Text Available The purpose of this study was to demonstrate the impact of certain lifestyles in our daily lives, and to reference some of them, among which are a sedentary lifestyle, diet, physical activity, social and family support, and the impact they have on people’ quality of life. It is clear that as a human beings, the developments in everyday life are addressed by duties and rights that affect our way of living, hence all individuals should enjoy the right to a better quality of life; to achieve this, it is necessary to maintain healthy lifestyle habits that create mechanisms to protect people against the development of chronic degenerative diseases. Historically it has been shown that people who have unhealthy life habits develop over time no only hypokinetic diseases, but also neurological ones such as Alzheimer's and Parkinson's. Under this scenario this paper is intended to present clear and concise information about what lifestyles represent to people and their importance as a right for everyone who decides to adapt them to their daily lives.

Therefore, in each of its corporate actions, BP always integrates the value of community, partnership, consultation and corporate responsibility. It is mentioned that through experience and observation, BP as an extractive company, haveestimated the costs of not finding a better mechanism to adjust to social challenges can be higher than the costs of the uncertainties inherent in the trial of new ideas. However, according to international Non-GovernmentalOrganization (NGO, Down to Earth, BP has conducted a series of human rights violations by exploiting natural resources in Papua and restricting Papuans in enjoying their fundamental human rights. If only the BP keeps this Tangguh project in line with its aim to accommodate concerns from the affected surroundings, thus, will surely bring positive changes in BP’s corporate shared value.

Conflicts of interest are inherent to the majority of relationships among individuals and of these with companies and institutions and, certainly, research involving human beings is no exception. In relation to clinical research, the main focus of this manuscript, conflicts of interest occur at different levels and usually permeate among them: In the pharmaceutical industry in their decisions to invest to develop new products, especially vaccines and drugs, and also in relation to marketing of these products; Among the investigators the conflicts may be related to the financial gains to participate in pharma sponsored trials, or to the expected academic career boost attained with the publication of the results of the trials and also to personal interests such as the financial support for trips to international conferences. Often the participation of host country investigators is restricted to performing phase III or IV protocols developed abroad, many times with low scientific relevance, and even lower relevance to public health; Universities or research institutes themselves also have conflicts of interest, as the sponsored projects may help increase their budgets, both directly (taxes) and indirectly (e.g., improvement of physical infrastructure of laboratories or out patient clinics); For the trial volunteers in developing countries, and Brazil is no exception despite free and universal access to its health system, participation in clinical trials is many times seen as, and can really be, an unique opportunity of receiving better health care, better treatment by the health professionals, easier access to costly lab exams and also to receiving certain medications which would otherwise be difficult to have access to. In order to handle these conflicts of interest, Brazil has a well-established and respected legal support and ethical normatization. The latter is represented by Resolution 196/96 of the Brazilian National Research Ethics Committee (CONEP). This
Emissions of greenhouse gases (GHG) are one of the greatest threats to our future prosperity. World emissions are currently around 50 billion tonnes of carbon dioxide-equivalent per annum and are growing rapidly. Atmospheric concentrations of GHG emissions in the atmosphere have increased, to over 400ppm of CO2e today, even after taking the offsetting radiative effects of aerosols into account, and are increasing at a rate of around 2.5ppm per year. The world's current lack of "adequate" commitments to reduce emissions are consistent with at least a 3oC rise (50-50 chance) in temperature: a temperature not seen on the planet for around 3 million years, with serious risks of 5oC rise: a temperature not seen on the planet for around 30 million years. So what are the implications of a 3-5oC rise in temperature, with associated changes in, rising sea levels, retreating mountain glaciers, melting of the Greenland ice cap, shrinking Arctic Sea ice, especially in summer, increasing frequency of extreme weather events, such as heat waves, floods, and droughts, and intensification of cyclonic events, such as hurricanes in the Atlantic. Even a 2oC increase in mean surface temperatures will adversely affect freshwater, food and fiber, natural ecosystems, coastal systems and low-lying areas, human health and social systems, especially in developing countries. The impacts of 3-5oC will be extensive, predominantly negative, undermine development and poverty alleviation goals and cut across most sectors. To address human-induced climate change requires a transition to a low carbon economy, which will require rapid technological evolution in the efficiency of energy use, environmentally sound low-carbon renewable energy sources and carbon capture and storage. The longer we wait to transition to a low carbon economy the more we are locked into a high carbon energy system with consequent environmental damage to ecological and socio-economic systems. Unfortunately the political will

Human cloning has become one of the most controversial debates about reproduction in Western civilization. Human cloning represents asexual reproduction, but the critics of human cloning argue that the result of cloning is not a new individual who is genetically unique. There is also awareness in the scientific community, including the medical community, that human cloning and the creation of clones are inevitable. Psychology and other social sciences, together with the natural sciences, will need to find ways to help the healthcare system, to be prepared to face the new challenges introduced by the techniques of human cloning. One of those challenges is to help the healthcare system to find specific standards of behaviour that could be used to help potential parents to interact properly with cloned babies or children created through genetic manipulation. In this paper, the concepts of personality, identity and uniqueness are discussed in relationship to the contribution of twin studies in these areas. The author argues that an individual created by human cloning techniques or any other type of genetic manipulation will not show the donor's characteristics to the extent of compromising uniqueness. Therefore, claims to such an effect are needlessly alarmist.

Women in the U.S. face significant structural constraints in attempting to breastfeed as recommended in the first six months of their child's life. Internet-facilitated human milk sharing is an emergent response to breastfeeding challenges. Little is known about the demographic characteristics of milk sharing donors and recipients and the ways structural factors circumscribe the biocultural context of lactation in milk sharing practices. Data regarding demographic characteristics, reproductive history, lactation history, and levels of social support and health care provider support for breastfeeding were collected via an online survey September 2013-March 2014. Statistical tests were executed to ascertain whether significant differences exist between donors and recipients. A total of 867 respondents (661 donors, 206 recipients) met the eligibility criteria for the study. Respondents were U.S. residents and primarily White, middle-class, well educated, and employed women. Both donors and recipients reported higher than the national average for household income, maternal educational attainment, breastfeeding exclusivity 0-6 months, and breastfeeding duration. Differences in lactation sufficiency and breastfeeding outcomes between donors and recipients were associated with both structural and biocultural factors. Donors reported significantly higher income, education, and support for breastfeeding from spouse/partner, other family, employers, and pediatricians. Donors also reported significantly higher rates of full term birth for child of most recent lactation. This study provides a foundation for understanding how milk sharing reflects a broader political economy of breastfeeding in the U.S. Copyright © 2014 Elsevier Ltd. All rights reserved.

Full Text Available The sharing of wild plant foods is infrequent in chimpanzees, but in chimpanzee communities that engage in hunting, meat is frequently used as a 'social tool' for nurturing alliances and social bonds. Here we report the only recorded example of regular sharing of plant foods by unrelated, non-provisioned wild chimpanzees, and the contexts in which these sharing behaviours occur. From direct observations, adult chimpanzees at Bossou (Republic of Guinea, West Africa very rarely transferred wild plant foods. In contrast, they shared cultivated plant foods much more frequently (58 out of 59 food sharing events. Sharing primarily consists of adult males allowing reproductively cycling females to take food that they possess. We propose that hypotheses focussing on 'food-for-sex and -grooming' and 'showing-off' strategies plausibly account for observed sharing behaviours. A changing human-dominated landscape presents chimpanzees with fresh challenges, and our observations suggest that crop-raiding provides adult male chimpanzees at Bossou with highly desirable food commodities that may be traded for other currencies.

Common sense suggests that romantic partners tend to be interdependent in their well-being and self-esteem. The authors tested the degree to which codevelopment in romantic partners (i.e., development in similar directions) is due to mutual influence between partners or due to the effects of shared environment, using longitudinal data from 5 samples of couples (N = 4,116 participants). The samples included dating, cohabiting, and married couples, with a broad age range covering young adulthood to old age. The authors used a longitudinal version of the actor-partner interdependence model and examined measures of well-being (life satisfaction, positive affect, negative affect, and depression) and self-esteem. After conducting the study-level analyses, we meta-analytically aggregated the findings across studies. The results showed significant mutual influence between partners in life satisfaction, positive affect, negative affect, and depression, and significant effects of shared environment on life satisfaction, positive affect, negative affect, depression, and self-esteem. The findings suggest that both mutual influence and shared environment account for codevelopment of well-being in romantic partners. In contrast, only shared environment but not mutual influence contributes to the partners' codevelopment of self-esteem. The findings have important implications because they show that the level of well-being of a person's relationship partner has long-term influence on the person's own well-being.

Two studies of the effects of perfume additives, termed human pheromones by the authors, have conveyed the message that these substances can promote an increase in human sociosexual behaviour [Physiol. Behav. 75 (2003) R1; Arch. Sex. Behav. 27 (1998) R2]. The present paper presents an extended analysis of this data. It is shown that in neither study is there a statistically significant increase in any of the sociosexual behaviours for the experimental groups. In the control groups of both studies, there are, however, moderate but statistically significant decreases in the corresponding behaviour. Most notably, there is no support in data for the claim that the substances increase the attractiveness of the wearers of the substances to the other sex. It is concluded that more research using matched homogenous groups of participants is needed. Copyright 2004 Elsevier Inc.

Full Text Available Although ecosystem services are increasingly recognized as benefits people obtain from nature, we still have a poor understanding of how they actually enhance multidimensional human well-being, and how well-being is affected by ecosystem change. We develop a concept of "ecosystem service elasticity" (ES elasticity that describes the sensitivity of human well-being to changes in ecosystems. ES Elasticity is a result of complex social and ecological dynamics and is context dependent, individually variable, and likely to demonstrate nonlinear dynamics such as thresholds and hysteresis. We present a conceptual framework that unpacks the chain of causality from ecosystem stocks through flows, goods, value, and shares to contribute to the well-being of different people. This framework builds on previous conceptualizations, but places multidimensional well-being of different people as the final element. This ultimately disaggregated approach emphasizes how different people access benefits and how benefits match their needs or aspirations. Applying this framework to case studies of individual coastal ecosystem services in East Africa illustrates a wide range of social and ecological factors that can affect ES elasticity. For example, food web and habitat dynamics affect the sensitivity of different fisheries ecosystem services to ecological change. Meanwhile high cultural significance, or lack of alternatives enhance ES elasticity, while social mechanisms that prevent access can reduce elasticity. Mapping out how chains are interlinked illustrates how different types of value and the well-being of different people are linked to each other and to common ecological stocks. We suggest that examining chains for individual ecosystem services can suggest potential interventions aimed at poverty alleviation and sustainable ecosystems while mapping out of interlinkages between chains can help to identify possible ecosystem service trade-offs and winners and

The distributions of three human ribosomal gene polymorphisms among individual chromosomes containing nucleolus organizers were analyzed by using mouse--human hybrid cells. Different nucleolus organizers can contain the same variant, suggesting the occurrence of genetic exchanges among ribosomal gene clusters on nonhomologous chromosomes. Such exchanges appear to occur less frequently in mice. This difference is discussed in terms of the nucleolar organization and chromosomal location of ribosomal gene clusters in humans and mice.

Eosinophils are leukocytes that are released into the peripheral blood in a phenotypically mature state and are capable of being recruited into tissues in response to appropriate stimuli. Eosinophils, traditionally considered cytotoxic effector cells, are leukocytes recruited into the airways of asthma patients where they are believed to contribute to the development of many features of the disease. This perception, however, has been challenged by recent findings suggesting that eosinophils have also immunomodulatory functions and may be involved in tissue homeostasis and wound healing. Here we describe a transcriptome-based approach-in a limited number of patients and controls-to investigate the activation state of circulating human eosinophils isolated by flow cytometry. We provide an overview of the global expression pattern in eosinophils in various relevant conditions, e.g., eosinophilic asthma, hypereosinophilic dermatological diseases, parasitosis and pulmonary aspergillosis. Compared to healthy subjects, circulating eosinophils isolated from asthma patients differed in their gene expression profile which is marked by downregulation of transcripts involved in antigen presentation, pathogen recognition and mucosal innate immunity, whereas up-regulated genes were involved in response to non-specific stimulation, wounding and maintenance of homeostasis. Eosinophils from other hypereosinophilic disorders displayed a very similar transcriptional profile. Taken together, these observations seem to indicate that eosinophils exhibit non-specific immunomodulatory functions important for tissue repair and homeostasis and suggest new roles for these cells in asthma immunobiology.

Human pluripotent stem cells (PSCs) have the capacity to revolutionize medicine by allowing the generation of functional cell types such as neurons for cell replacement therapy. However, the more immediate impact of PSCs on treatment of Alzheimer's disease (AD) will be through improved human AD model systems for mechanistic studies and therapeutic screening. This review will first briefly discuss different types of PSCs and genome-editing techniques that can be used to modify PSCs for disease modeling or for personalized medicine. This will be followed by a more in depth analysis of current AD iPSC models and a discussion of the need for more complex multicellular models, including cell types such as microglia. It will finish with a discussion on current clinical trials using PSC-derived cells and the long-term potential of such strategies for treating AD. Copyright © 2015 Elsevier Ltd. All rights reserved.

The concept of knowledge management has, indeed, become a buzzword that every single organization is expected to practice and live by. Knowledge management is about managing the organization's knowledge for the common good of the organization -but practicing knowledge management is not as simple...... as that. This article focuses on knowledge sharing as the process seeking to reduce the resources spent on reinventing the wheel.The article introduces the concept of time sensitiveness; i.e. that knowledge is either urgently needed, or not that urgently needed. Furthermore, knowledge sharing...... is considered as either a push or pull system. Four strategies for sharing knowledge - help, post-it, manuals and meeting, and advice are introduced. Each strategy requires different channels for sharing knowledge. An empirical analysis in a production facility highlights how the strategies can be practiced....

Full Text Available Abstract Background Human resources are an essential element of a health system's inputs, and yet there is a huge disparity among countries in how human resource policies and strategies are developed and implemented. The analysis of the impacts of services on population health and well-being attracts more interest than analysis of the situation of the workforce in this area. This article presents an international comparison of the health workforce in terms of skill mix, sociodemographics and other labour force characteristics, in order to establish an evidence base for monitoring and evaluation of human resources for health. Methods Profiles of the health workforce are drawn for 18 countries with developed market and transitional economies, using data from labour force and income surveys compiled by the Luxembourg Income Study between 1989 and 1997. Further descriptive analyses of the health workforce are conducted for selected countries for which more detailed occupational information was available. Results Considerable cross-national variations were observed in terms of the share of the health workforce in the total labour market, with little discernible pattern by geographical region or type of economy. Increases in the share were found among most countries for which time-trend data were available. Large gender imbalances were often seen in terms of occupational distribution and earnings. In some cases, health professionals, especially physicians, were overrepresented among the foreign-born compared to the total labour force. Conclusions While differences across countries in the profile of the health workforce can be linked to the history and role of the health sector, at the same time some common patterns emerge, notably a growing trend of health occupations in the labour market. The evidence also suggests that gender inequity in the workforce remains an important shortcoming of many health systems. Certain unexpected patterns of

Full Text Available The Birdman of India, Salim Moizuddin Abdul Ali, was one of the first Indians to conduct a systematic and patterned survey of birds in India. W.S. Millard, the Secretary of the Bombay Natural History Society (BNHS had introduced Salim Ali to the beautiful world of the birds. Millard had identified an unusually coloured sparrow that was actually shot by a young Salim Ali with his air gun. This was a yellow-throated sparrow. Following this, Millard showed Salim Ali the Society’s collection of stuffed birds, and this became the beginning of a marvelous journey of exploring the bird kingdom and establishing great landmarks by Salim Ali. The sparrow had transformed Salim Ali’s world. Undoubtedly, his autobiography was later titled ‘The Fall of a Sparrow’. Salim Ali has very carefully noted in his autobiography as to how this yellow-throated sparrow became the turning point in his life that led him into the fascinating world of ornithology. This research contribution is not about the birdman but the bird, which is rapidly vanishing from our vicinity. The reasons for the decline of the sparrow are varied but the fact of the matter is that the natural world around us is rapidly receding. And the decline of the sparrow is an alarm, a warning against the degrading ecosystems, and an alarm against blind-folded urbanisation which is leading to human-induced disasters.

The use of information and communication technologies (ICTs) for information sharing among family members is increasing dramatically. However, little is known about the associated factors and the influence on family well-being. The authors investigated the pattern and social determinants of family life information sharing with family and the associations of different methods of sharing with perceived family health, happiness, and harmony (3Hs) in Hong Kong, where mobile phone ownership and Internet access are among the most prevalent, easiest, and fastest in the world. A territory-wide population-based telephone survey was conducted from January to August 2016 on different methods of family life information (ie, information related to family communication, relationships with family members, emotion and stress management) sharing with family members, including face-to-face, phone, instant messaging (IM), social media sites, video calls, and email. Family well-being was assessed by three single items on perceived family health, happiness, and harmony, with higher scores indicating better family well-being. Adjusted prevalence ratios were used to assess the associations of sociodemographic factors with family life information sharing, and adjusted beta coefficients for family well-being. Of 2017 respondents, face-to-face was the most common method to share family life information (74.45%, 1502/2017), followed by IM (40.86%, 824/2017), phone (28.10%, 567/2017), social media sites (11.91%, 240/2017), video calls (5.89%, 119/2017), and email (5.48%, 111/2017). Younger age and higher education were associated with the use of any (at least one) method, face-to-face, IM, and social media sites for sharing family life information (all P for trend face-to-face, and IM (all P for trend face-to-face (beta=0.62, 95% CI 0.45-0.80) and video calls (beta=0.34, 95% CI 0.04-0.65).

South Asia harbors one of the highest levels genetic diversity in Eurasia, which could be interpreted as a result of its long-term large effective population size and of admixture during its complex demographic history. In contrast to Pakistani populations, populations of Indian origin have been underrepresented in previous genomic scans of positive selection and population structure. Here we report data for more than 600,000 SNP markers genotyped in 142 samples from 30 ethnic groups in India. Combining our results with other available genome-wide data, we show that Indian populations are characterized by two major ancestry components, one of which is spread at comparable frequency and haplotype diversity in populations of South and West Asia and the Caucasus. The second component is more restricted to South Asia and accounts for more than 50% of the ancestry in Indian populations. Haplotype diversity associated with these South Asian ancestry components is significantly higher than that of the components dominating the West Eurasian ancestry palette. Modeling of the observed haplotype diversities suggests that both Indian ancestry components are older than the purported Indo-Aryan invasion 3,500 YBP. Consistent with the results of pairwise genetic distances among world regions, Indians share more ancestry signals with West than with East Eurasians. However, compared to Pakistani populations, a higher proportion of their genes show regionally specific signals of high haplotype homozygosity. Among such candidates of positive selection in India are MSTN and DOK5, both of which have potential implications in lipid metabolism and the etiology of type 2 diabetes.

In an atomic power plant, it is necessary to provide sufficient informations concerning the quantity of state in the plant to the operators. However, an atomic power plant is apt to have a black box in its operation because of the automatized systems to avoid human errors. Thus, the informations of plant are needed to be provided in fitting forms for human cognitive functions. Here, an investigation was made focusing on the feedback of operation results and the presentation of the plant states in the PWR plant model. In addition, exchange and sharing of informations as well as role assignment in the operational support among groups were investigated using duty officers on bridge of a modern coastwise tanker as the subjects. To prevent an error manipulation during intelligent works in plant operation, a model room for virtual reality experiment was constructed. Then, an input system for sensory feedback and its plant model were proposed to examine the validity of the feedback inputs. (M.N.)

Full Text Available Bipolar disorder (BPD is a debilitating heritable psychiatric disorder. Contemporary rodent models for the manic pole of BPD have primarily utilized either single locus transgenics or treatment with psychostimulants. Our lab recently characterized a mouse strain termed Madison (MSN that naturally displays a manic phenotype, exhibiting elevated locomotor activity, increased sexual behavior, and higher forced swimming relative to control strains. Lithium chloride and olanzapine treatments attenuate this phenotype. In this study, we replicated our locomotor activity experiment, showing that MSN mice display generationally-stable mania relative to their outbred ancestral strain, hsd:ICR (ICR. We then performed a gene expression microarray experiment to compare hippocampus of MSN and ICR mice. We found dysregulation of multiple transcripts whose human orthologs are associated with BPD and other psychiatric disorders including schizophrenia and ADHD, including: Epor, Smarca4, Cmklr1, Cat, Tac1, Npsr1, Fhit, and P2rx7. RT-qPCR confirmed dysregulation for all of seven transcripts tested. Using a novel genome enrichment algorithm, we found enrichment in genome regions homologous to human loci implicated in BPD in replicated linkage studies including homologs of human cytobands 1p36, 3p14, 3q29, 6p21-22, 12q24, 16q24, and 17q25. Using a functional network analysis, we found dysregulation of a gene system related to chromatin packaging, a result convergent with recent human findings on BPD. Our findings suggest that MSN mice represent a polygenic model for the manic pole of BPD showing much of the genetic systems complexity of the corresponding human disorder. Further, the high degree of convergence between our findings and the human literature on BPD brings up novel questions about evolution by analogy in mammalian genomes.
Full Text Available Following gender prescriptions can affect individuals’ quality of life. Research has shown that the unequal distribution of household labor is correlated with low psychological well-being and family conflict. Therefore, negotiations concerning household and family duties within relationships appear to be an important health-related issue. Additionally, research has shown that couples who have more gender-egalitarian arrangements within their households have better health outcomes if the wider society is more gender egalitarian. In this literature review, we aim to shed light on the relationship of the equal division of housework between women and men with their health and well-being. We also present selected results from the series of studies conducted during our PAR Migration Navigator project, which explores the practices of gender equality within households and their relationship to individual well-being among Polish couples living in Poland, Polish migrant couples living in Norway, and Norwegian couples living in Norway.

Dixon School of the Arts students have partnered with From the Ground Up Community Garden to learn more about gardening and to start a school garden in Pensacola, Florida. There are many soils options to learn about and test. Just this year ECUA, Emerald Coast Utilities Authority developed a new compost using biosolids. While they advertise that it is safe to grow food in, there are many discrepancies within the local organic garden communities. This project will be designed to determine if local food can be grown in the soil, if it grows bigger and better than alternative soils and finally if it is safe to eat.

Background: Using photographs and in-depth interviews, this study provides nuanced insight into influences on first-year PhD students’ lived experiences, with a specific focus on these students’ perceptions of doctoral student well-being. Methodology: Twenty-nine first-year biomedical science PhD students from 15 research institutions were asked to take photographs (Participant Produced Images to illuminate significant influences on their research skill acquisition. The participant-produced photographs were discussed within in-depth phone interviews allowing for a deeper understanding of their lived experiences. Contribution: While students were asked to identify factors influencing their research skill acquisition, unexpectedly, what emerged from these data was students’ clear focus on their concern for their physical and mental well-being. The researchers posit that students’ ability to create a “work-life balance” is the foundation of doctoral student success, especially in the early years of doctoral training. Findings: Findings suggest that it is essential to create a PhD culture in which students feel valued, supported, and nourished, both physically and mentally, for them to develop into successful researchers, teachers, and mentors. Recommendations for Practitioners: Findings suggest that doctoral programs must support a more collaborative work environment for students and help novice students create a work life balance, perhaps by encouraging them to pursue stimulating or fun activities outside their school environment. It is imperative for doctoral students to be confident during their doctoral studies, as a lack of confidence tends to breathe life into poor work habits that stymie well-being and happiness. Recommendation for Researchers: If doctoral programs support a culture that facilitates

Smallpox, caused by variola virus, was a terror for civilizations around the world for more than 3000 years. Although the disease is eradicated, hundreds of variola virus isolates are kept in two WHO-collaborating facilities, one in USA and one in Russia. In spite of several agreements on destruction, it is now doubtful that these virus isolates will be destroyed. Variola virus may exist in other places and may be used as a biological weapon in war or for terror. Further research on variola virus is thus essential in order to achieve a better understanding of the pathogenicity of the virus and to develop new anti-variola virus vaccines and antiviral drugs.

The pharmacologic effects of intravenous injections of iopentol (Nycomed AS, Oslo, Norway) in 24 healthy male volunteers were studied. Doses from 300 to 1200 mg I/kg b.w. were well tolerated. Some persons had a slight heat sensation, abnormal abdominal sensations, thirst, or nausea. Headache was reported in a few subjects both after iopentol and saline injections, and was considered to be procedure related. No severe events occurred. Minor changes were observed in some biochemical and physiological parameters, but were usually within normal ranges and without clinical importance. Some of these effects also occurred in the control group after saline injections. Iopentol was excreted mainly in the urine and no metabolites were detected. The results indicated that clinical trials with iopentol could be undertaken. (author). 7 refs.; 2 tabs

Since the early seventies, potential health risks from ELF (Extremely Low frequency electromagnetic Fields) exposure (50 Hz) have been extensively treated in the literature (more than 1000 references registered by WHO (World Health Organisation), 2007). After 30 years of worldwide research, the major epidemiological output is the possible modest increased risk (by a factor 2) of childhood leukaemia in case of a long exposure to an ambient magnetic flux density (B-field) higher than 0.4 μT. However, this fact has not been confirmed by in vivo and in vitro studies. Moreover it has not been validated by any adverse health biological mechanisms neither for adults nor for children. International recommendations (ICNIRP, International Commission on Non-Ionising Radiation Protection) are currently, for general public, not to exceed a B-field of 100 μT (50 Hz) and an E-field of 5 kV/m (50 Hz). Herein, a rough overview of typical values of ELF fields will be presented followed by a brief literature survey on childhood leukaemia and ELF The potential carcinogenic effect of ELF would be linked to electrical disturbances in cell behaviour. The major concern linking child-hood leukaemia and ELF is thus to determine the response of bone marrow cells under ELF fields. With that purpose, transmembrane potential will be targeted and linked to the E-field at that level. This paper is three-folded: (1) the electric interactions between ambient ELF fields and the body are studied both qualitatively and quantitatively. Different sources of internal E-field are analysed and classified according to their potential risk; (2) the hypothesis of contact current is detailed; (3) key actions to undertake are highlighted. Based on the current state of the art and some authors' own developments, this paper proposes simple low cost enhancements of private electrical installations in order to annihilate the major source of potential effects of ELF.

Full Text Available In the last approximately 15 years, mainly in the last decade, Romania made substantial efforts to establish the institutions fighting THB according with the EU’s Directive 38 /2011’s requirements and the recommendation assumed by the International Treaties signed and ratified in this area. The plethora of institutions were founded, but they are not functioning yet as a system because of the absence of the independent assessing institution. That is why, it must be, immediately, created. Beside, the institutional system needs, as a unavoidable complement the launching of Cultural Strategy in tabooing for good, the THB in Romania.

Japan has for decades been a first-mover and pacemaker with respect to the development of humanoid and android robots . In this conceptual paper, we aim to demonstrate how certain android robotic projects can be embedded and interpreted within a Japanese notion of nature, where the artificial...... is not opposed to nature and where conventionalized idealizations in general are cherished over original state of the latter . Furthermore, we will discuss how android robots epitomize challenges to the macro and micro levels of society.  J. Robertson, Robo Sapiens Japanicus: Robots, Gender, Family...
Based on four reactor safety components (namely: a) God-given safety, b) Equipment safety, c) Quick-response safety, d) Containing safety), categorical assessment is made of various nuclear reactor concepts ranging from present existing reactors to future reactors based on innovative reactor design. In pursuit of nuclear reactor safety, ultimate characteristics of the ideal nuclear reactor are expected to coincide with those of an inherently safe reactor. A definition of 'inherently safe' has already been proposed by a committee in Japan. As a realistic and existable reactor, which is as close to the ideal reactor, a future reactor which is almost the same as a global reactor, is proposed. This global reactor must be constructable anywhere on earth and must permit easy operation and maintenance by anyone. It is also discussed to identify what behavior is expected of the global reactor under various conditions. At the same time, this future reactor which includes the global reactor, should solve a) the nuclear fuel resource issue, b) efficient utilization of fission energy and c) environmental issues as the greenhouse effect.

An antibody to human granulocytes was raised in rabbits by immunization with granulocytes pretreated with rabbit antibody to contaminating antigens. The antibody reacted not only with granulocytes but also with monocytes and bone marrow granulocyte precursors including colony-forming units in culture (CFU-C). In tests with leukemic cells, the antibody reacted with blasts from most (8 of 9) patients with acute myelomonoblastic leukemia and from some patients with acute myeloblastic leukemia, morphologically undifferentiated acute leukemia and chronic myelogenous leukemia in blast crisis. The antibody did not react with blasts from patients with acute lymphoblastic leukemia nor with leukemic cells from patients with chronic lymphocytic leukemia.

Genetic variants underlying complex traits, including disease susceptibility, are enriched within the transcriptional regulatory elements, promoters and enhancers. There is emerging evidence that regulatory elements associated with particular traits or diseases share similar patterns of transcriptional activity. Accordingly, shared transcriptional activity (coexpression) may help prioritise loci associated with a given trait, and help to identify underlying biological processes. Using cap analysis of gene expression (CAGE) profiles of promoter- and enhancer-derived RNAs across 1824 human samples, we have analysed coexpression of RNAs originating from trait-associated regulatory regions using a novel quantitative method (network density analysis; NDA). For most traits studied, phenotype-associated variants in regulatory regions were linked to tightly-coexpressed networks that are likely to share important functional characteristics. Coexpression provides a new signal, independent of phenotype association, to enable fine mapping of causative variants. The NDA coexpression approach identifies new genetic variants associated with specific traits, including an association between the regulation of the OCT1 cation transporter and genetic variants underlying circulating cholesterol levels. NDA strongly implicates particular cell types and tissues in disease pathogenesis. For example, distinct groupings of disease-associated regulatory regions implicate two distinct biological processes in the pathogenesis of ulcerative colitis; a further two separate processes are implicated in Crohn's disease. Thus, our functional analysis of genetic predisposition to disease defines new distinct disease endotypes. We predict that patients with a preponderance of susceptibility variants in each group are likely to respond differently to pharmacological therapy. Together, these findings enable a deeper biological understanding of the causal basis of complex traits.
Full Text Available The emergence of the modern human mind and modern human behaviour is a prominent issue in palaeolithic archaeology. The consensus has been that modernity, understood in terms of increased rates of innovation and the emergence of symbolism, is enabled by a heritable neurophysiology unique to Homo sapiens. This consensus is characterised as biological essentialist in that it understands modernity as genotypically specified and unique to Homo sapiens. 'Archaic' hominins such as the Neanderthals are understood to have lacked the modern neuroanatomical genotype and therefore to have been innately incapable of modern cognition and behaviour. The biological-essentialist programme, however, is facing a serious challenge as evidence for innovation and symbolism is found in the archaeological records of the Eurasian Middle Palaeolithic and the African Middle Stone Age. An alternative programme is emerging that understands modern human behaviour as an emergent property of social, demographic and ecological dynamics. It is argued that this programme is currently inadequate since it cannot explain the emergence of symbolically charged material culture and relies on inexorable long-term population growth. It is suggested here that the problem is better understood in terms of hierarchy theory, a body of ideas concerned with systems organised on multiple scales. Palaeolithic behaviour is reconceptualised as social practice emerging from a multi-scale knowledge system. It is shown that enhancements in the rate at which knowledgeable practices disseminate through social fields – the social transmission of knowledge - will have the effect of increasing the likelihood that novel practices will be incorporated into long-term structuring principles and thus become persistent practices. They will also effect a scalar convergence of domains of knowledgeability such that technical practices become incorporated into the construction of personhood as meaningful or

Helping, i.e. behaviour increasing the fitness of others, can evolve when directed towards kin or reciprocating partners. These predictions have been tested in the context of food sharing both in human foragers and non-human primates. Here, we performed quantitative meta-analyses on 32 independent study populations to (i) test for overall effects of reciprocity on food sharing while controlling for alternative explanations, methodological biases, publication bias and phylogeny and (ii) compare the relative effects of reciprocity, kinship and tolerated scrounging, i.e. sharing owing to costs imposed by others. We found a significant overall weighted effect size for reciprocity of r = 0.20-0.48 for the most and least conservative measure, respectively. Effect sizes did not differ between humans and other primates, although there were species differences in in-kind reciprocity and trade. The relative effect of reciprocity in sharing was similar to those of kinship and tolerated scrounging. These results indicate a significant independent contribution of reciprocity to human and primate helping behaviour. Furthermore, similar effect sizes in humans and primates speak against cognitive constraints on reciprocity. This study is the first to use meta-analyses to quantify these effects on human helping and to directly compare humans and other primates.

Medium-sized food manufacturing enterprises in Indonesia are significant in a number of contexts, in terms of their part to the national production (GDP) and their establishment to the employment. In term of their role to national production, manufacturing sector contributes the highest GDP by 85%. In this sector, food manufacturing subsector contributes the highest GDP. Nevertheless, they faced the same common problems: quality of human capital and sustainability issues. Previous government supplementary programs have been established to expand the human capital capability amongst medium enterprises. Adequate amount of fund has been apportioned to develop human capital, though, the medium enterprises sustainability is still in question. This study proposes and examines the human capital role from informal knowledge sharing perspective. By conducting qualitative approach through interviews to four informants in Indonesian medium-sized food manufacturing enterprises, a set of hypotheses is derived from this study for future quantitative study. This study indicates that human capital traits (diverse education background, employee skills, and employee experience) could leverage the practice of informal knowledge sharing. Constructs such as mutual trust and reciprocal intention could play as mediating variables, and cultural interpretation perspective could act as moderating factor to informal knowledge sharing effectiveness. In final, informal knowledge sharing is indicated to play as moderating variable for human capital policy and practice to support enterprise sustainability.

Full Text Available John Ronald Reuel Tolkien's collection The Silmarillion, which is a utopic creation myth of Middle-earth, Valinor, Numenor and Beleriand, and his novel The Lord of the Rings, which is a saga taking place only in Middle-earth, seem to be completely irrelevant to George Orwell's dystopian world 1984 at first view but when they are examined in detail, two striking common points would be obvious that these myths support the idea of cultural variety's importance and they consist of a war against cultural dominance. In The Lord of the Rings, it is the battle and collaboration of cultures that makes sense in the mythological surrounding of the plot; the creatures come together to defend their cultural history against a single body; Sauron and the Orcs under his rule. As for 1984, the reader is presented with the struggle of a couple, Winston and Julia, to continue their cultural heritage against the dictatorship of Ingsoc which offers the society with an artificial and prototypical culture.
Full Text Available Grammatical markers are not uniformly impaired across speakers of different languages, even when speakers share a diagnosis and the marker in question is grammaticalized in a similar way in these languages. The aim of this work is to demarcate, from a cross-linguistic perspective, the linguistic phenotype of three genetically heterogeneous developmental disorders: specific language impairment, Down syndrome, and autism spectrum disorder. After a systematic review of linguistic profiles targeting mainly English-, Greek-, Catalan-, and Spanish-speaking populations with developmental disorders (n = 880, shared loci of impairment are identified and certain domains of grammar are shown to be more vulnerable than others. The distribution of impaired loci is captured by the Locus Preservation Hypothesis which suggests that specific parts of the language faculty are immune to impairment across developmental disorders. Through the Locus Preservation Hypothesis, a classical chicken and egg question can be addressed: Do poor conceptual resources and memory limitations result in an atypical grammar or does a grammatical breakdown lead to conceptual and memory limitations? Overall, certain morphological markers reveal themselves as highly susceptible to impairment, while syntactic operations are preserved, granting support to the first scenario. The origin of resilient syntax is explained from a phylogenetic perspective in connection to the “syntax-before-phonology” hypothesis.

This paper applies the methods of multi-dimensional mathematical demography to project national populations based on alternative assumptions on future, fertility, mortality, migration and educational transitions that correspond to the five shared socioeconomic pathways (SSP) storylines. In doing so it goes a significant step beyond past population scenarios in the IPCC context which considered only total population size. By differentiating the human population not only by age and sex-as is conventionally done in demographic projections-but also by different levels of educational attainment the most fundamental aspects of human development and social change are being explicitly addressed through modeling the changing composition of populations by these three important individual characteristics. The scenarios have been defined in a collaborative effort of the international Integrated Assessment Modeling community with the medium scenario following that of a major new effort by the Wittgenstein Centre for Demography and Global Human Capital (IIASA, OEAW, WU) involving over 550 experts from around the world. As a result, in terms of total world population size the trajectories resulting from the five SSPs stay very close to each other until around 2030 and by the middle of the century already a visible differentiation appears with the range between the highest (SSP3) and the lowest (SSP1) trajectories spanning 1.5 billion. The range opens up much more with the SSP3 reaching 12.6 billion in 2100 and SSP1 falling to 6.9 billion which is lower than today's world population.

Sustainable ecosystem services supply is the basis of regional sustainable development, and human beings can satisfy and improve their well-being through ecosystem services consumption. To understand the relationships between ecosystem services supply and consumption and human well-being is of vital importance for coordinating the relationships between the conservation of ecosystem services and the improvement of human well-being. This paper summarized the diversity, complexity, and regionality of ecosystem services supply, the diversity and indispensability of ecosystem services consumption, and the multi-dimension, regionality, and various evaluation indices of human well-being, analyzed the uncertainty and multi-scale correlations between ecosystem services supply and consumption, and elaborated the feedback and asynchronous relationships between ecosystem services and human well-being. Some further research directions for the relationships between ecosystem services supply and consumption and human well-being were recommended.

It had has the objective of knowing and understanding the needs, antenatal care values and beliefs of pregnant women in the context of Prenatal Service of a Philanthropic Institution. The central theme "be treated as a Human Being", identified from the analysis of the cultural themes, revealed that, in the women experience, the most significant element is represented either by the effective interaction or by the establishment on bond of trust between them and nurse.
Commentary is provided on the transition mankind has made from a maintained population growth rate of 2% to adaptation to a more civilized age. When the agricultural age began 100,000 years ago, man was still tribal, and it may well be that scientists are correct in postulating that adaptation is slow. Homo sapiens are still tribal or tried to family or kin groups, rather than to the nations state. These ties to family and tribe may contribute to present day "ethnic cleansing" and the illusion of the notion of a family of all peoples. In the past, families had to be large in order to sustain life; there was still a high death rate which slowed population growth. Population reached 2 billion in 1930 after a million years of growth. Mankind's tinkering with nature produced science and technology, which eliminated the natural balance of mortality. The consequence was a doubling of population in 47 years between 1930 to 1977 to 4 billion people. BY 1987, in just 10 years, another billion was added. Homo sapiens must not act responsible and influence the birth side by practicing "contraception control." Unfortunately, the force of habit has obliterated the reasons for large families, and humans have "unwittingly defied procreation from being merely a means to the status of an end." There is nothing in the Bible that forbids contraception or mentions multiplying in an irresponsible way. Neither this vast increase in population, which presently grows at 95 million per year, nor scientific advancement has eliminated mortality or disease. Million suffer from malnutrition and starvation, and the distribution of resources has been unequal and moves in the direction of resource depletion and environmental degradation. The formula for living must change; families need to plan for few children. Fighting to kill as a means of population control is unacceptable. Human beings possess the intelligence to preserve individual and social human life in a responsible way.

Kenrick et al. (2010, this issue) make an important contribution by presenting a theory of human needs within an evolutionary framework. In our opinion, however, this framework bypasses the human uniqueness that Maslow intended to capture in his theory. We comment on the unique power of culture in shaping human motivation at the phylogenetic, ontogenetic, and proximate levels. We note that culture-gene coevolution may be a more promising lead to a theory of human motivation than a mammalcentric evolutionary perspective. © The Author(s) 2010.
Interpretation: This study reports, for the first time, naturally acquired infections in humans with parasites termed as P. brasilianum. We conclude that quartan malaria parasites are easily exchanged between humans and monkeys in Latin America. We hypothesize a lack of host specificity in mammalian hosts and consider quartan malaria to be a true anthropozoonosis. Since the name P. brasilianum suggests a malaria species distinct from P. malariae, we propose that P. brasilianum should have a nomenclatorial revision in case further research confirms our findings. The expansive reservoir of mammalian hosts discriminates quartan malaria from other Plasmodium spp. and requires particular research efforts.

Robots are becoming an increasingly pervasive feature of our personal lives. As a result, there is growing importance placed on examining what constitutes appropriate behavior when they interact with human beings. In this paper, we discuss whether companion robots should be permitted to "nudge" their human users in the direction of being "more ethical". More specifically, we use Rawlsian principles of justice to illustrate how robots might nurture "socially just" tendencies in their human counterparts. Designing technological artifacts in such a way to influence human behavior is already well-established but merely because the practice is commonplace does not necessarily resolve the ethical issues associated with its implementation.
Full Text Available Phytoviruses are highly prevalent in plants worldwide, including vegetables and fruits. Humans, and more generally animals, are exposed daily to these viruses, among which several are extremely stable. It is currently accepted that a strict separation exists between plant and vertebrate viruses regarding their host range and pathogenicity, and plant viruses are believed to infect only plants. Accordingly, plant viruses are not considered to present potential pathogenicity to humans and other vertebrates. Notwithstanding these beliefs, there are many examples where phytoviruses circulate and propagate in insect vectors. Several issues are raised here that question if plant viruses might further cross the kingdom barrier to cause diseases in humans. Indeed, there is close relatedness between some plant and animal viruses, and almost identical gene repertoires. Moreover, plant viruses can be detected in non-human mammals and humans samples, and there are evidence of immune responses to plant viruses in invertebrates, non-human vertebrates and humans, and of the entry of plant viruses or their genomes into non-human mammal cells and bodies after experimental exposure. Overall, the question raised here is unresolved, and several data prompt the additional extensive study of the interactions between phytoviruses and non-human mammals and humans, and the potential of these viruses to cause diseases in humans.
Escherichia coli alpha hemolysin (AH) evoked a luminol-amplified chemiluminescence (CL) response from human polymorphonuclear leukocytes (PMN). Analysis of kinetic parameters of the PMN CL response to AH established similarities with that of PMN to the calcium ionophore A23187. PMN CL responses to both AH and A23187 were equally decreased by preincubating PMN with A63612, a hidroxamic acid derivative and lipooxigenase inhibitor, showing that the CL response to both hemolysin and ionophore share a common mechanism, probably activation of leukotriene synthesis, due to calcium entry into the cells brought about by AH and A23187. In addition, the CL response of PMN to AH was lowered by the hydroxyl radical scavenger dimethyl sulfoxide, further suggesting arachidonate metabolism is involved in CL response. (Author) [es

In today's media environment, information is not simply passed from producers to consumers, but is mediated by participants of new media cultures, including information on sexual health. In focus groups held in Sydney and regional Australia in 2011, we asked young people aged 16-22 about the potential for sexual health promotion via Facebook and other social media. Our findings point to the complex ways in which young people use social media, and the unlikelihood of traditional take-home sexual health messages having traction in social media spaces. Five key aspects which emerged were: the participatory culture of social network sites; the stigma of sexual health, especially sexually transmitted infections (STIs); young people's careful presentations of self; privacy concerns; and the importance of humour in sexual health messaging. Fears of bullying and gossip (or 'drama') were also likely to prevent the dissemination of sexual health messages in this environment. However, humorous online videos were noted by participants as a significant way to avoid stigma and enable the sharing of sexual health information. The young people in our study were interested in sexual health information, but did not want to access it at the cost of their own sense of comfort and belonging in their social networks. Any sexual health promotion within these sites must be understood as a site-specific intervention. Copyright © 2013 Reproductive Health Matters. Published by Elsevier Ltd. All rights reserved.

Biophysics, just by looking at its name, indicates an interdisciplinary scientific activity, although the notion of interdisciplinarity, as such, seems to be not widely or specifically discussed by biophysicists. The same seems to have happened as well in the early stages of the development of cybernetics, notably in Norbert Wiener's writings. This situation seems to contrast with what has happened in subsequent developments of cybernetics ideas, notably in general system theory and cognitive sciences. After a few general reflections on the notion of interdisciplinarity, its sophisticated variants and the path leading to the birth of cognitive science, we shall refer to Wiener's thought to extracts aspects and indications that could be useful today, also for what concerns the social responsibility of scientists, which could be seen as stemming from a very general form of interdisciplinarity.

The quartan malaria parasite Plasmodium malariae is the widest spread and best adapted human malaria parasite. The simian Plasmodium brasilianum causes quartan fever in New World monkeys and resembles P. malariae morphologically. Since the genetics of the two parasites are nearly identical, differing only in a range of mutations expected within a species, it has long been speculated that the two are the same. However, no naturally acquired infection with parasites termed as P. brasilianum has been found in humans until now. We investigated malaria cases from remote Yanomami indigenous communities of the Venezuelan Amazon and analyzed the genes coding for the circumsporozoite protein (CSP) and the small subunit of ribosomes (18S) by species-specific PCR and capillary based-DNA sequencing. Based on 18S rRNA gene sequencing, we identified 12 patients harboring malaria parasites which were 100% identical with P. brasilianum isolated from the monkey, Alouatta seniculus. Translated amino acid sequences of the CS protein gene showed identical immunodominant repeat units between quartan malaria parasites isolated from both humans and monkeys. This study reports, for the first time, naturally acquired infections in humans with parasites termed as P. brasilianum. We conclude that quartan malaria parasites are easily exchanged between humans and monkeys in Latin America. We hypothesize a lack of host specificity in mammalian hosts and consider quartan malaria to be a true anthropozoonosis. Since the name P. brasilianum suggests a malaria species distinct from P. malariae, we propose that P. brasilianum should have a nomenclatorial revision in case further research confirms our findings.

Although cigarette smoke (CS) is the primary risk factor for chronic obstructive pulmonary disease (COPD), the underlying molecular mechanisms for the significant variability in developing COPD in response to CS are incompletely understood. We performed lung gene expression profiling of two different wild-type murine strains (C57BL/6 and NZW/LacJ) and two genetic models with mutations in COPD genome-wide association study genes (HHIP and FAM13A) after 6 months of chronic CS exposure and compared the results to human COPD lung tissues. We identified gene expression patterns that correlate with severity of emphysema in murine and human lungs. Xenobiotic metabolism and nuclear erythroid 2-related factor 2-mediated oxidative stress response were commonly regulated molecular response patterns in C57BL/6, Hhip +/- , and Fam13a -/- murine strains exposed chronically to CS. The CS-resistant Fam13a -/- mouse and NZW/LacJ strain revealed gene expression response pattern differences. The Fam13a -/- strain diverged in gene expression compared with C57BL/6 control only after CS exposure. However, the NZW/LacJ strain had a unique baseline expression pattern, enriched for nuclear erythroid 2-related factor 2-mediated oxidative stress response and xenobiotic metabolism, and converged to a gene expression pattern similar to the more susceptible wild-type C57BL/6 after CS exposure. These results suggest that distinct molecular pathways may account for resistance to emphysema. Surprisingly, there were few genes commonly modulated in mice and humans. Our study suggests that gene expression responses to CS may be largely species and model dependent, yet shared pathways could provide biologically significant insights underlying individual susceptibility to CS.

This is discussion about the relationship between elderly human beings with ostomy and their environments care, under the perspective of Complexity Edgar Morin. An axis holds the reflection: environments of care for elderly humans with ostomy. In this sense, we present three types of environment that surround the context of elderly humans with ostomy: home environment, group environment and hospital environment. This brings, as a social contribution, a new look about resizing caring of elderly humans with ostomy in their environment. It is considered that the environment hosting this human being contains a diversity of feelings, emotions, experiences; it binds multiple meanings, from the Complexity perspective, about the relationship between the environment and the caring process.

OBJECTIVE: (1) To describe the importance chronically ill and disabled patients attach to involvement in decision-making when various care types are considered, and (2) to analyse the degree to which these patients are involved in shared decision-making (SDM) regarding these care types, and whether
This article is a selective review of quantitative research, historical and prospective, that is needed to inform sustainable development policy. I start with a simple framework to highlight how demography and productivity shape human well-being. I use that to discuss three sets of issues and corresponding challenges to modeling: first, population prehistory and early human development and their implications for the future; second, the multiple distinct dimensions of human and environmental well-being and the meaning of sustainability; and, third, inequality as a phenomenon triggered by development and models to examine changing inequality and its consequences. I conclude with a few words about other important factors: political, institutional, and cultural.

Keynote: Family relationships are normatively assumed to be characterized by ‘sharing’, such as living together in the same home, occupying the same place, sharing stuff, blood and biology, spending special and ordinary time together, and consequently creating shared biographical experiences....... In that way, families are thrown into togetherness. At the same time, we see families in varying forms where 'sharing' is lived and contested differently. In Denmark, many children live in nuclear families, and many live in different variations of more than one household. For those who share household...... and family, 'sharing' will be a basic condition. No matter what, they should share life circumstances, more stories, more places and spaces, more households families with both kin and non-kin. This keynote addresses the particular of children’s experiences of living apart and/or living together in sharing...

Human prosociality is one of the defining characteristics of our species, yet the ontogeny of altruistic behavior remains poorly understood. The evolution of widespread food sharing in humans helped shape cooperation, family formation, life history, language, and the development of economies of scale. While the behavioral and ecological correlates of food sharing among adults are widely studied, very little is known about food sharing among children. Here, in the first study to analyze the food sharing patterns of hunter-gatherer children, we show that while sharing may be biased towards kin, reciprocity characterizes the majority of all sharing dyads, both related and unrelated. These data lend support to the recent claim that discrimination among kin might be linked with reciprocal altruism theory. Furthermore, we show that age positively correlates with an increase in sharing, both in frequency and amount, supporting recent suggestions that prosocial behaviors and egalitarianism develop strongly in middle childhood when children acquire the normative rules of their society.

Full Text Available Allegedly, Heidegger never quite finished Being and Time: his initial intention had consisted in the determination of the meaning of Being as such, apart from Dasein’s own existentiality. Afterwards, however, and despite the growing public excitement revolving around the published unfinished version of his project, his preoccupations, thematic conceptuality and very language, apparently started to shift away towards a strange and unfamiliar stance which he would never leave. Quite surely, his Nazi flirtation and subsequent withdrawal did not help in bringing clarity over this. On the other hand, this was not necessarily unexpected (although not necessarily to be expected, as well. What I mean to say is that for someone reading Being and time in spirit and not in law, the possibility of such a substantive rethought of his initial scheme is present throughout the work. One’s changing one’s mind with respect to oneself is, after all, one of the basic possibilities conveyed by Dasein’s achieved resoluteness [Entschlossenheit]. Furthermore, despite his apparent reorientation, I think we can speak of some sort of attitudinal unity between Heidegger’s initial and later work, conceptually mediated by the relationship between Dasein’s Being-unto-death [Sein-zum-Tode] and the so called concealedness [Verborgenheit] of Being.. That is precisely what I aim to lay bare through this conceptual reconstruction of some of his later works: (i On the Essence of Truth (1930 and (ii Letter on Humanism (1946. Basically, I will try to show that if in Being and Time he tried to come to Being from Dasein, in his later work he tries to get to Da-sein from Being, fact which unsurprisingly brought along some reconsiderations but that, broadly speaking, essentially amounts to what he set out to do in his initial ontological project. Surprisingly, the most concrete instance of this pendulation between Dasein and Being is to be found, at least to my knowledge, in

Rheumatoid arthritis (RA) is a chronic systemic autoimmune disorder of unknown etiology, which is characterized by inflammation in the synovium and joint damage. Although the pathogenesis of RA remains to be determined, a combination of environmental (e.g., viral infections) and genetic factors influence disease onset. Especially genetic factors play a vital role in the onset of disease, as the heritability of RA is 50–60%, with the human leukocyte antigen (HLA) alleles accounting for at least 30% of the overall genetic risk. Some HLA-DR alleles encode a conserved sequence of amino acids, referred to as the shared epitope (SE) structure. By analyzing the structure of a HLA-DR molecule in complex with Epstein-Barr virus (EBV), the SE motif is suggested to play a vital role in the interaction of MHC II with the viral glycoprotein (gp) 42, an essential entry factor for EBV. EBV has been repeatedly linked to RA by several lines of evidence and, based on several findings, we suggest that EBV is able to induce the onset of RA in predisposed SE-positive individuals, by promoting entry of B-cells through direct contact between SE and gp42 in the entry complex.

One of the most important applications of transgenic animals for medical purposes is to transplant their organs into human's body, an issue which has caused a lot of ethical and scientific discussions. we can divide the ethical arguments to two comprehensive groups; the first group which is known as deontological critiques (related to the action itself regardless of any results pointing the human or animal) and the second group, called the consequentialist critiques (which are directly pointing the consequences of the action). The latter arguments also can be divided to two subgroups. In the first one which named anthropocentrism, just humankind has inherent value in the moral society, and it studies the problem just from a human-based point of view while in second named, biocentrism all the living organism have this value and it deals specially with the problem from the animal-based viewpoint. In this descriptive-analytic study, ethical issues were retrieved from books, papers, international guidelines, thesis, declarations and instructions, and even some weekly journals using keywords related to transgenic animals, organ, and transplantation. According to the precautionary principle with the strong legal and ethical background, due to lack of accepted scientific certainties about the safety of the procedure, in this phase, transplanting animal's organs into human beings have the potential harm and danger for both human and animals, and application of this procedure is unethical until the safety to human will be proven.

According to the 2011 Census of India, over 31% of India's 1.2 billion people lived in nearly 8000 towns and cities; the remaining 830 million people lived in over 638,000 villages. About 55% of rural households and 93% of urban households had access to electricity. The 2005 Indian Human Development Survey showed that on average, electricity availability (hours of supply per day) in rural and urban households were 14 and 19 h, respectively (Desai et al., 2007). Using nationally representative data from Indian Human Development Survey, this study estimated the impact of electricity access and availability on two attributes of human well-being, viz. education and health attainment. It found a significant positive relationship between electricity availability and well-being in rural and urban households. Electricity accessibility, revealed a significant positive relationship only for rural households. The paper concludes with implications for electricity policy and infrastructure choices. - Graphical abstract: Impact of electricity security on the attributes of human well-being. - Highlights: • Nexus between well-being, and electricity access and availability is quantified. • Electricity access is positively associated with well-being in rural but not urban. • Electricity availability negatively associates with morbidity and absenteeism. • Electricity security as human well-being enabler seeks nuanced policy attention. • Decentralized rapidly deployable modular technologies and microgrids are advocated

Human collaboration in distributed knowledge sharing groups depends on the functionality of information and communication technologies (ICT) to support performance. Since many of these dynamic environments are constrained by time limits, knowledge must be shared efficiently by adapting the level of information detail to the specific situation. This paper focuses on the process of knowledge and context sharing with and without mediation by ICT, as well as issues to be resolved when determining appropriate ICT channels. Both technology-rich and non-technology examples are discussed.

To probe the correlation between the postmortem interval (PMI) and the DNA degradation of costicartilage and dental pulp cells in human being after death, and to seek a new method for estimating PMI. The image cytometry was used to measure the DNA degradation under different ambient temperatures (30-35 degrees C, 15-20 degrees C) in 0-15 days after death. The average DNA content of two kinds of tissue was degradated with the prolongation of PMI. But there was a plateau period of 0-4 days for dental pulp cells of human being in 15-20 degrees C. There was a high negative correlativity PPMI. PMI could be estimated accurately according to the DNA degradation of costicartilage and dental pulp cells in human being after death.

Full Text Available Introduction: the objective of this paper is to deeply and clearly explain the internationalisation of higher education from the aspect of the integration of human being with urban cultural space. Materials and Methods: the methods used in the research are mainly analytical and descriptive ones enabling to show how the integration of human being and urban cultural space promote and influence the internationalisation of higher education. Results: the motivation for the internationalisation of higher education is closely interrelated with that of urbanisation. Besides the economic and political incentives, modern urban culture, caused by globalisation, also plays a very important role in encouraging higher education internationalisation. Discussion and Conclusions: the appearance of higher education internationalisation is mediated by the alteration of the existing environment of urban culture space against the background of city internationalisation. Human beings’ need for self-assurance in urban culture space helps to stimulate the internationalisation of higher education, and human beings promote the development of modern culture space and their separation in urban culture space accelerates the development of higher education. From the perspective of higher education internationalisation, to sort out the cultural motivation for higher education and find its suitable form for the city’s internationalisation is crucial for adjusting the orientation and guaranteeing the efficacy of higher education internationalisation. From the aspect of human beings’ development, the separation between urban space and human beings caused by the city’s ongoing internationalisation is a pressing problem to be solved. From the aspect of the construction of urban culture space, as an important means of retaining human beings’ equilibrium, urban culture promotes the internationalisation of higher education.

This essay examines core contributions of a model of psychological well-being that has had widespread scientific impact. It drew on distant formulations to identify new dimensions and measures for assessing what it means to be well. Key themes among the more than 750 studies using the model are sketched, followed by reflections about why there has been so much interest in this eudaimonic approach to well-being. A final section looks to the future, proposing new directions to illuminate the forces that work against the realization of human potential as well as those that nurture human flourishing and self-realization.

Conservationists are increasingly engaging with the concept of human well-being to improve the design and evaluation of their interventions. Since the convening of the influential Sarkozy Commission in 2009, development researchers have been refining conceptualizations and frameworks to understand and measure human well-being and are starting to converge on a common understanding of how best to do this. In conservation, the term human well-being is in widespread use, but there is a need for guidance on operationalizing it to measure the impacts of conservation interventions on people. We present a framework for understanding human well-being, which could be particularly useful in conservation. The framework includes 3 conditions; meeting needs, pursuing goals, and experiencing a satisfactory quality of life. We outline some of the complexities involved in evaluating the well-being effects of conservation interventions, with the understanding that well-being varies between people and over time and with the priorities of the evaluator. Key challenges for research into the well-being impacts of conservation interventions include the need to build up a collection of case studies so as to draw out generalizable lessons; harness the potential of modern technology to support well-being research; and contextualize evaluations of conservation impacts on well-being spatially and temporally within the wider landscape of social change. Pathways through the smog of confusion around the term well-being exist, and existing frameworks such as the Well-being in Developing Countries approach can help conservationists negotiate the challenges of operationalizing the concept. Conservationists have the opportunity to benefit from the recent flurry of research in the development field so as to carry out more nuanced and locally relevant evaluations of the effects of their interventions on human well-being. © 2014 The Authors.

Sharing and reusing anatomical models over the Web offers a significant opportunity to progress the investigation of cardiovascular diseases. However, the current sharing methodology suffers from the limitations of static model delivery (i.e. embedding static links to the models within Web pages) and of a disaggregated view of the model metadata produced by publications and cardiac simulations in isolation. In the context of euHeart--a research project targeting the description and representation of cardiovascular models for disease diagnosis and treatment purposes--we aim to overcome the above limitations with the introduction of euHeartDB, a Web-enabled database for anatomical models of the heart. The database implements a dynamic sharing methodology by managing data access and by tracing all applications. In addition to this, euHeartDB establishes a knowledge link with the physiome model repository by linking geometries to CellML models embedded in the simulation of cardiac behaviour. Furthermore, euHeartDB uses the exFormat--a preliminary version of the interoperable FieldML data format--to effectively promote reuse of anatomical models, and currently incorporates Continuum Mechanics, Image Analysis, Signal Processing and System Identification Graphical User Interface (CMGUI), a rendering engine, to provide three-dimensional graphical views of the models populating the database. Currently, euHeartDB stores 11 cardiac geometries developed within the euHeart project consortium.
Full Text Available MicroRNAs have been long considered synthesized endogenously until very recent discoveries showing that human can absorb dietary microRNAs from animal and plant origins while the mechanism remains unknown. Compelling evidences of microRNAs from rice, milk, and honeysuckle transported to human blood and tissues have created a high volume of interests in the fundamental questions that which and how exogenous microRNAs can be transferred into human circulation and possibly exert functions in humans. Here we present an integrated genomics and computational analysis to study the potential deciding features of transportable microRNAs. Specifically, we analyzed all publicly available microRNAs, a total of 34,612 from 194 species, with 1,102 features derived from the microRNA sequence and structure. Through in-depth bioinformatics analysis, 8 groups of discriminative features have been used to characterize human circulating microRNAs and infer the likelihood that a microRNA will get transferred into human circulation. For example, 345 dietary microRNAs have been predicted as highly transportable candidates where 117 of them have identical sequences with their homologs in human and 73 are known to be associated with exosomes. Through a milk feeding experiment, we have validated 9 cow-milk microRNAs in human plasma using microRNA-sequencing analysis, including the top ranked microRNAs such as bta-miR-487b, miR-181b, and miR-421. The implications in health-related processes have been illustrated in the functional analysis. This work demonstrates the data-driven computational analysis is highly promising to study novel molecular characteristics of transportable microRNAs while bypassing the complex mechanistic details.

This report presents a comprehensive set of recommendations for protection of human beings who are trafficked for the purpose of organ removal or are targeted for such trafficking. Developed by an interdisciplinary group of international experts under the auspices of the project Trafficking in Human Beings for the Purpose of Organ Removal (also known as the HOTT project), these recommendations are grounded in the view that an individual who parts with an organ for money within an illegal scheme is ipso facto a victim and that the crime of trafficking in human beings for the purpose of organ removal (THBOR) intersects with the crime of trafficking in organs. Consequently, the protection of victims should be a priority for all actors involved in antitrafficking activities: those combating organ-related crimes, such as health organizations and survivor support services, and those combating trafficking in human beings, such as the criminal justice sectors. Taking into account the special characteristics of THBOR, the authors identify 5 key stakeholders in the protection of human beings trafficked for organ removal or targeted for such trafficking: states, law enforcement agencies and judiciary, nongovernmental organizations working in the areas of human rights and antitrafficking, transplant centers and health professionals involved in transplant medicine, and oversight bodies. For each stakeholder, the authors identify key areas of concern and concrete measures to identify and protect the victims of THBOR. The aim of the recommendations is to contribute to the development of a nonlegislative response to THBOR, to promote the exchange of knowledge and best practices in the area of victim protection, and to facilitate the development of a policy-driven action plan for the protection of THBOR victims in the European Union and worldwide.

, sequences corresponding to the shared promoter region of the CYPT family were identified at 39 loci. Most loci were located immediately upstream of genes belonging to the VCX/Y, SPANX, or CSAG gene families. Sequence comparison of the loci revealed a conserved CYPT promoter-like (CPL) element featuring TATA...... cell types. The genomic regions harboring the gene families were rich in direct and inverted segmental duplications (SD), which may facilitate gene conversion and rapid evolution. The conserved CPL and the common expression profiles suggest that the human VCX/Y, SPANX, and CSAG2 gene families together......Many testis-specific genes from the sex chromosomes are subject to rapid evolution, which can make it difficult to identify murine genes in the human genome.

Bombyx mori (silkworm) is the most famous lepidopteran in Japan. B. mori has long been used in the silk industry and also as a model insect for agricultural research. In recent years, B. mori has attracted interest in its potential for use in pathological analysis of model animals. For example, the human macular carotenoid transporter was discovered using information of B. mori carotenoid transporter derived from yellow-cocoon strain. The B. mori carotenoid transport system is useful in human studies. To develop a human disease model, we characterized the human homologs of B. mori, and by constructing KAIKO functional annotation pipeline, and to analyze gene expression profile of a unique B. mori mutant strain using microarray analysis. As a result, we identified a novel molecular network involved in Parkinson's disease. Here we describe the potential use of a spontaneous mutant silkworm strain as a human disease model. We also summarize recent progress in the application of genomic information for annotation of human homologs in B. mori. The B. mori mutant will provide a clue to pathological mechanisms, and the findings will be helpful for the development of therapies and for medical drug discovery.

The human microbiome is affected by multiple factors, including the environment and host genetics. In this study, we analyzed the salivary microbiomes of an extended family of Ashkenazi Jewish individuals living in several cities and investigated associations with both shared household and host genetic similarities. We found that environmental effects dominated over genetic effects. While there was weak evidence of geographical structuring at the level of cities, we observed a large and significant effect of shared household on microbiome composition, supporting the role of the immediate shared environment in dictating the presence or absence of taxa. This effect was also seen when including adults who had grown up in the same household but moved out prior to the time of sampling, suggesting that the establishment of the salivary microbiome earlier in life may affect its long-term composition. We found weak associations between host genetic relatedness and microbiome dissimilarity when using family pedigrees as proxies for genetic similarity. However, this association disappeared when using more-accurate measures of kinship based on genome-wide genetic markers, indicating that the environment rather than host genetics is the dominant factor affecting the composition of the salivary microbiome in closely related individuals. Our results support the concept that there is a consistent core microbiome conserved across global scales but that small-scale effects due to a shared living environment significantly affect microbial community composition. IMPORTANCE Previous research shows that the salivary microbiomes of relatives are more similar than those of nonrelatives, but it remains difficult to distinguish the effects of relatedness and shared household environment. Furthermore, pedigree measures may not accurately measure host genetic similarity. In this study, we include genetic relatedness based on genome-wide single nucleotide polymorphisms (SNPs) (rather than

Throughout human history, pandemic bacterial diseases such as the plague and tuberculosis have posed an enormous threat to human beings. The discovery of antibiotics has provided us with powerful arsenal for the defense against bacterial infections. However, bacteria are acquiring more and more resistance genes to shield off antibiotics through mutation and horizontal gene transfer. Therefore, novel antibiotics must be produced and the arms race between bacterial pathogens and antibiotics is becoming increasingly intense. Recently, researchers have found that plasmids carrying a new metallo-beta-lactamase gene, blaNDM-1, and many other antibiotics resistance genes can easily spread through bacterial populations and confer recipient stains resistance to nearly all of the current antibiotics. It is a threat to the human health and a great challenge for our medical science, which we are facing. We need to find new ways to fight and win this arms racing.

In this introductory essay, we explore definitions of the ‘sharing economy’, a concept indicating both social (relational, communitarian) and economic (allocative, profit-seeking) aspects which appear to be in tension. We suggest combining the social and economic logics of the sharing economy to focus on the central features of network enabled, aggregated membership in a pool of offers and demands (for goods, services, creative expressions). This definition of the sharing economy distinguishe...

Poverty is not solely a social or political matter, nor is it caused simply by population pressures as Thomas Malthus postulated in 1798. A new understanding of poverty is emerging in which natural and environmental drivers, together with social, political, and demographic causes, underpin livelihoods. The Earth sciences, therefore, play a critical role in identifying the deep causes of human suffering and in identifying solutions. The State of the Planet: Why Are So Many So Poor? For far too many, the state of human well-being is bleak. Around one in six human beings-1 billion people-live in extreme poverty, struggling to survive on less than $1 a day; another one sixth of humanity ekes out existence on $2 per day (U.N. Development Programme (UNDP) Human Development Report, 2004; http://hdr.undp.org/2004/). The extreme poor lack all normal attributes of a decent, dignified life: adequate food, housing, sanitation, health care, education, and employment. Some 800 million people lack sufficient nourishment almost every day. It stunts their mental and physical development and shortens their lives, making them susceptible to common illnesses that attack their hunger-weakened bodies. Poor nutrition in mothers and infants is the leading cause of reduced disability-adjusted life years in poor countries [ Economist, 2004].
The National Institutes of Health (NIH) announced its plans to lift its moratorium on funding research that involves injecting human embryonic stem cells into animal embryos, which would allow for the creation of part-human and part-animal organisms known as chimeras. The NIH allowed only one month to receive public comments in the midst of a presidential election campaign. Lifting the moratorium means that, for the first time, the federal government will begin spending taxpayer dollars on the creation and manipulation of new organisms that would blur the line between humans and animals. Interestingly, this government effort is creating an uncommon coalition between pro-life groups and animal rights activists that oppose this medical research on ethical grounds; the former seeking to ensure the welfare of human embryos and the latter seeking to protect the well-being of animals. Unlike the issue of abortion, this research is complex. Yet, it is important that the pro-life laity and clergy be adequately informed on some of the basic science and ethics that surround this research. To fully understand why this research is unethical and why the NIH is pursuing this particular research, it is important to understand the ethical tenets governing human-subject research and why secular scientists are pursuing this scientific field.

I have attempted to show that the differential qualities of animals and human beings indeed to have bearing on moral rules and the derivation of rights, including rights established on the basis of reason and utilitarianism. Special rights for members of our species are not simply a consequence of human domination and self-interest. I also have tried to show that rights arise from values and that the qualities we value most highly often are the ones that distinguish human beings from other species. I maintain that giving more value to human lives over animal lives achieves reflective balance with the commonsense notions that most of us have developed. Because utilitarianism, contractualism, and the classical philosophical methods of Kant and Aristotle all may allow favoring human interests over animal interests, it seems reasonable to suspect that animal rights activists embrace narrow, extremist views. There are many uniquely human experiences to which we ascribe high value-deep interpersonal relationships, achieving a life's goal, enjoying a complex cultural event such as a play or an opera, or authoring a manuscript. Therefore, it would seem improper that social and ethical considerations regarding animals be centered entirely on the notion of a biological continuum, because there are many kinds of human experience-moral, religious, aesthetic, and otherwise-that appear to be outside the realm of biology. Knowledge about the biology of animals is helpful for making moral decisions about our obligations to them. Why, then, is there a substantial population of animal rights activists in Europe, the United States, and throughout the world, who would not agree with my conclusions? Certain habitual ways of thinking may encourage anthropomorphism and equating animal interests with human interests.

Pharmacogenomics is a hybrid field of experimental science at the intersection of human disease genetics and clinical pharmacology sharing applications of the new genomic technologies. But this hybrid field is not yet stable or fully integrated, nor is science policy in pharmacogenomics fully equipped to resolve the challenges of this emerging hybrid field. The disciplines of human disease genetics and clinical pharmacology contain significant differences in their scientific practices. Whereas clinical pharmacology originates as an experimental science, human disease genetics is primarily observational in nature. The result is a significant asymmetry in scientific method that can differentially impact the degree to which gene-environment interactions are discerned and, by extension, the study sample size required in each discipline. Because the number of subjects enrolled in observational genetic studies of diseases is characteristically viewed as an important criterion of scientific validity and reliability, failure to recognize discipline-specific requirements for sample size may lead to inappropriate dismissal or silencing of meritorious, although smaller-scale, craft-based pharmacogenomic investigations using an experimental study design. Importantly, the recognition that pharmacogenomics is an experimental science creates an avenue for systematic policy response to the ethical imperative to prospectively pursue genetically customized therapies before regulatory approval of pharmaceuticals. To this end, we discuss the critical role of interdisciplinary engagement between medical sciences, policy, and social science. We emphasize the need for development of shared standards across scientific, methodologic, and socioethical epistemologic divides in the hybrid field of pharmacogenomics to best serve the interests of public health.

As part of a wider study into human resource management (HRM) practices in project-oriented organizations, we investigated the issue of employee well-being. Project-oriented organizations adopt temporary work processes to deliver products and services to clients. This creates a dynamic work environment, where additional pressures can be imposed on the employee from fluctuating work-loads, uncertain requirements, and multiple role demands. These pressures can create issues for employee well-be...
Full Text Available We take a social-ecological systems perspective to investigate the linkages between ecosystem services and human well-being in South Africa. A recent paper identified different types of social-ecological systems in the country, based on distinct bundles of ecosystem service use. These system types were found to represent increasingly weak direct feedbacks between nature and people, from rural "green-loop" communities to urban "red-loop" societies. Here we construct human well-being bundles and explore whether the well-being bundles can be used to identify the same social-ecological system types that were identified using bundles of ecosystem service use. Based on national census data, we found three distinct well-being bundle types that are mainly characterized by differences in income, unemployment and property ownership. The distribution of these well-being bundles approximates the distribution of ecosystem service use bundles to a substantial degree: High levels of income and education generally coincided with areas characterised by low levels of direct ecosystem service use (or red-loop systems, while the majority of low well-being areas coincided with medium and high levels of direct ecosystem service use (or transition and green-loop systems. However, our results indicate that transformations from green-loop to red-loop systems do not always entail an immediate improvement in well-being, which we suggest may be due to a time lag between changes in the different system components. Using human well-being bundles as an indicator of social-ecological dynamics may be useful in other contexts since it is based on socio-economic data commonly collected by governments, and provides important insights into the connections between ecosystem services and human well-being at policy-relevant sub-national scales.

The use of meteoric 10Be as a tool to understand long term landscape behavior is becoming increasingly popular. Due its high residence time, meteoric 10Be allows in principle to investigate in situ erosion rates over time scales exceeding the period studied with classical approaches such as 137Cs. The use of meteoric 10Be strongly contributes to the traditional interpretation of sedimentary archives which cannot be unequivocally coupled to sediment production and could provide biased information over longer time scales (Sadler, 1981). So far, meteoric 10Be has successfully been used in geochemical fingerprinting of sediments, to date soil profiles, to assess soil residence times and to quantify downslope soil fluxes using accumulated 10Be inventories along a hill slope. However, less attention is given to the potential use of the tracer to directly asses human induced changes in soil fluxes through deforestation, cultivation and reforestation. A good understanding of the processes governing the distribution of meteoric 10Be both within the soil profile and at landscape scale is essential before meteoric 10Be can be successfully applied to assess human impact. We developed a spatially explicit 2D-model (Be2D) in order to gain insight in meteoric 10Be movement along a hillslope that is subject to human disturbance. Be2D integrates both horizontal soil fluxes and vertical meteoric 10Be movement throughout the soil prolife. Horizontal soil fluxes are predicted using (i) well studied geomorphical laws for natural erosion and soil formation as well as (ii) human accelerated water and tillage erosion. Vertical movement of meteoric 10Be throughout the soil profile is implemented by inserting depth dependent retardation calculated using experimentally determined partition coefficients (Kd). The model was applied to different environments such as (i) the Belgian loess belt, characterized by aeolian deposits enriched in inherited meteoric 10Be, (ii) highly degraded and stony

A method has been devised to extrapolate biological equilibrium levels between animal species and subsequently to humans. Our initial premise was based on the observation that radionuclide retention is normally a function of metabolism so that direct or indirect measures could be described by a power law based on body weights of test animal species. However, we found that such interspecies comparisons ought to be based on the coefficient of the power equation rather than on the exponential parameter. The method is illustrated using retention data obtained from five non-ruminant species (including humans) that were fed radionuclides with different properties. It appears that biological equilibrium level for radionuclides in man can be estimated using data from mice, rats, and dogs. The need to extrapolate low-dose effects data obtained from small animals (usually rodents) to humans is not unique to radiation dosimetry or radiation protection problems. Therefore, some quantitative problems connected with estimating low-dose effects from other disciplines have been reviewed, both because of the concern about effects induced by the radionuclide moiety of a radiopharmaceutical and those of the nonradioactive component. The possibility of extrapolating low-dose effects calculated from animal studies to human is discussed

Simultaneous infection by multiple parasite species (viruses, bacteria, helminths, protozoa or fungi) is commonplace. Most reports show co-infected humans to have worse health than those with single infections. However, we have little understanding of how co-infecting parasites interact within human hosts.

Companion animals comprise a wide variety of species, including dogs, cats, horses, ferrets, guinea pigs, reptiles, birds and ornamental fish, as well as food production animal species, such as domestic pigs, kept as companion animals. Despite their prominent place in human society, little is known about the role of companion animals as sources of viruses for people and food production animals. Therefore, we reviewed the literature for accounts of infections of companion animals by zoonotic viruses and viruses of food production animals, and prioritized these viruses in terms of human health and economic importance. In total, 138 virus species reportedly capable of infecting companion animals were of concern for human and food production animal health: 59 of these viruses were infectious for human beings, 135 were infectious for food production mammals and birds, and 22 were infectious for food production fishes. Viruses of highest concern for human health included hantaviruses, Tahyna virus, rabies virus, West Nile virus, tick-borne encephalitis virus, Crimean-Congo haemorrhagic fever virus, Aichi virus, European bat lyssavirus, hepatitis E virus, cowpox virus, G5 rotavirus, influenza A virus and lymphocytic choriomeningitis virus. Viruses of highest concern for food production mammals and birds included bluetongue virus, African swine fever virus, foot-and-mouth disease virus, lumpy skin disease virus, Rift Valley fever virus, porcine circovirus, classical swine fever virus, equine herpesvirus 9, peste des petits ruminants virus and equine infectious anaemia virus. Viruses of highest concern for food production fishes included cyprinid herpesvirus 3 (koi herpesvirus), viral haemorrhagic septicaemia virus and infectious pancreatic necrosis virus. Of particular concern as sources of zoonotic or food production animal viruses were domestic carnivores, rodents and food production animals kept as companion animals.

Regarding this failure to take such life processes into account, and given its propensity for generalization, science stood out among these spheres as placing an excessive weight on positivist values that by their very nature disregarded anything that could not be classified as such. This approach was in stark contrast with the open tradition upheld by Miguel de Unamuno that would be eagerly taken up by Spanish philosophy in the twentieth century. From the perspective of that philosophy it is, therefore, worth asking whether all of those aspects and elements (not only those that form part of any given human life but also those belonging to the other two main spheres of culture – art and morality – displaced by scientism because they were not positive or verifiable through experiment, because they did not lend themselves to being understood using a rationalist or logical/scientific reasoning were not also human. Was their rejection justified?

A rotavirus VP4 gene P allele has been documented in a number of countries to be characteristically associated with an endemic predominantly asymptomatic infection in neonates in maternity hospital nurseries. The mechanisms underlying the endemicity and asymptomatic nature of such neonatal infections remain unknown. Rotavirus strains sharing this same P genotype, however, have more recently been recovered from an increasing number of symptomatic diarrheal episodes in infants and young children in various parts of the world. Previously, we have shown that an asymptomatic P rotavirus neonatal infection is not associated with a unique VP7 (G) serotype but may occur in conjunction with various G types. Although amino acid sequence comparisons of the VP4 gene between selected 'asymptomatic' and 'symptomatic' P rotavirus strains have been reported and yielded information concerning their VP4 genotypes, serotypic comparisons of the outer capsid spike protein VP4 of such viruses have not been studied systematically by two-way cross-neutralizations. We determined the VP4 neutralization specificities of four asymptomatic and four symptomatic P strains: two each of asymptomatic and symptomatic strains by two-way tests, and two each of additional asymptomatic and symptomatic strains by one-way tests. Both asymptomatic and symptomatic P strains were shown to bear similar, if not identical, VP4 neutralization specificities. Thus, P rotavirus strains causing asymptomatic or symptomatic infections did not appear to belong to unique P (VP4) serotypes. In addition, a close VP4 serotypic relationship between human P rotavirus strains and the porcine P rotavirus Gottfried strain was confirmed
Full Text Available In the animal world, various kinds of collective motions have been found and proven to be efficient ways of carrying out some activities such as searching for food and avoiding predators. Many scholars research the interactions of collective behaviors of human beings according to the rules of collective behaviors of animals. Based on the Lennard-Jones potential function and a self-organization process, our paper proposes a topological communication model to simulate the collective behaviors of human beings. In the results of simulations, we find various types of collective behavior and fission behavior and discover the threshold for the emergence of collective behavior, which is the range five to seven for the number of topology K. According to the analysis of network properties of the model, the in-degree of individuals is always equal to the number of topology. In the stable state, the out-degrees of individuals distribute around the value of the number of topology K, except that the out-degree of a single individual is approximately double the out-degrees of the other individuals. In addition, under different initial conditions, some features of different kinds of networks emerge from the model. We also find the leader and herd mentality effects in the characteristics of the behaviors of human beings in our model. Thus, this work could be used to discover how to promote the emergence of beneficial group behaviors and prevent the emergence of harmful behaviors.

In Tanzania, the National Water Policy (NAWAPO) of 2002 clearly stipulates that access to water supply and sanitation is a right for every Tanzanian and that cost recovery is the foundation of sustainable service delivery. To meet these demands, water authorities have introduced cost recovery and a water sharing system. The overall objective of this study was to assess the impact of cost recovery and the sharing system on water policy implementation and human rights to water in four villages in the Ileje district. The specific objectives were: (1) to assess the impact of cost recovery and the sharing system on the availability of water to the poor, (2) to assess user willingness to pay for the services provided, (3) to assess community understanding on the issue of water as a human right, (4) to analyse the implications of the results in relation to policies on human rights to water and the effectiveness of the implementation of the national water policy at the grassroots, and (5) to establish the guidelines for water pricing in rural areas. Questionnaires at water demand, water supply, ability and willingness to pay and revenue collection were the basis for data collection. While 36.7% of the population in the district had water supply coverage, more than 73,077 people of the total population of 115,996 still lacked access to clean and safe water and sanitation services in the Ileje district. The country's rural water supply coverage is 49%. Seventy-nine percent of the interviewees in all four villages said that water availability in litres per household per day had decreased mainly due to high water pricing which did not consider the income of villagers. On the other hand, more than 85% of the villagers were not satisfied with the amount they were paying because the services were still poor. On the issue of human rights to water, more than 92% of the villagers know about their right to water and want it exercised by the government. In all four villages, more than
Full Text Available Tissue-resident macrophages, such as microglia, Kupffer cells, and Langerhans cells, derive from Myb-independent yolk sac (YS progenitors generated before the emergence of hematopoietic stem cells (HSCs. Myb-independent YS-derived resident macrophages self-renew locally, independently of circulating monocytes and HSCs. In contrast, adult blood monocytes, as well as infiltrating, gut, and dermal macrophages, derive from Myb-dependent HSCs. These findings are derived from the mouse, using gene knockouts and lineage tracing, but their applicability to human development has not been formally demonstrated. Here, we use human induced pluripotent stem cells (iPSCs as a tool to model human hematopoietic development. By using a CRISPR-Cas9 knockout strategy, we show that human iPSC-derived monocytes/macrophages develop in an MYB-independent, RUNX1-, and SPI1 (PU.1-dependent fashion. This result makes human iPSC-derived macrophages developmentally related to and a good model for MYB-independent tissue-resident macrophages, such as alveolar and kidney macrophages, microglia, Kupffer cells, and Langerhans cells.

Techniques are described in detail for the RIA of human Ep in unextracted plasma or serum. With 100 μl of sample, the assay is sensitive at an Ep concentration of approximately 4 mU/ml, and when required, the sensitivity can be increased to 0.4 mU/ml, a range considerably less than the concentration observed in normal human beings. This is approximately 100 times more sensitive than existing in vivo bioassays for this hormone. Studies concerned with the validation of the Ep RIA show a high degree of correlation with the polycythemic mouse bioassay. Dilutions of a variety of human serum samples show a parallel relationship with the standard reference preparation for Ep. Validation of the RIA is further confirmed by observations of appropriate increases or decreases of circulating Ep levels in physiological and clinical conditions known to be associated with stimulation or suppression of Ep secretion. Significantly different mean serum concentrations of 17.2 mU/ml for normal male subjects and 18.8 mU/ml for normal female subjects were observed. Mean plasma Ep concentrations in patients with polycythemia vera are significantly decreased, and those of patients with secondary polycythemia are significantly increased as compared to plasma levels in normal subjects. These results demonstrate an initial practical value of the Ep RA in the hematology clinic, which will most certainly be expanded with its more extensive use

The cities of today present requirements that are dissimilar to those of the past. There are cities where the industrial and service sectors are in decline, and there are other cities that are just beginning their journey into the technological and industrial sectors. In general, the political and social realms have been restructured in terms of economics, which has resulted in an entirely different shape to the primitive structures of civilization. As people begin to understand the dynamic nature of landscapes, they stop seeing landscapes as a static scene. Sustainable cities must be simultaneously economically viable, socially just, politically well managed and ecologically sustainable to maximize human comfort. The present research suggests a multi-disciplinary approach for attaining a holistic understanding of urban environmental quality and human well-being in relation to sustainable urban development.

The plenary meetings were devoted to harmonization of the electromagnetic protection standards of Russia and western countries. The above conference constitutes one of the stages of the WHO international program concerning electromagnetic fields and the human being [ru
Full Text Available Introduction. The incorporation of mobile phones in the daily life of human being not only alters space and time dimensions, but it also changes the perception and the way we relate with the ecosystem. Methodology. The state of the art is analyzed from the technological concept of intimacy, used by Boyce and Hancock, which describes the levels of interaction between man and technology. Then, a methodology to explore issues increasingly pressing is proposed, especially, concerning the delimitation of public and private spheres and the interaction in the common space. Results and conclusions. Following in particular the theories of Castells, Heidegger, Meyrowitz and Habermas; a set of categories for deepening the concepts of spatialization, willingness and profile are articulated. These concepts are identified as key elements in this first stage of the project for the analysis of the human being as a communication portal.

Background: The close relationship between human health, performance, well-being and the thermal environment is obvious. Nevertheless, most studies of climate and climate change impacts show amazing shortcomings in the assessment of the environment. Populations living in different climates have different susceptibilities, due to socio-economic reasons, and different customary behavioural adaptations. The global distribution of risks of hazardous thermal exposure has not been analysed before. ...

World Health Organization recommends that girls, ages 9-13 years, get the human papilloma virus (HPV) vaccine. Global Alliance for Vaccines Initiative, which provides low-cost vaccine to eligible countries, requires that an additional intervention to be offered alongside the vaccine. We systematically searched and assessed the published literature in lower- and middle-income countries to identify effective interventions. We conducted systematic searches of four databases: PubMed, EMBASE, Global Index Medicus Regional Databases, and Cochrane Reviews for effective adolescent health interventions that could be delivered with the HPV vaccine in the following areas: (1) iron and folic acid supplementation (iron alone or with folic acid); (2) voucher delivery and cash transfer programs; (3) hand washing and soap provision; (4) vision screening; (5) promotion of physical activity/exercise; (6) menstrual hygiene education; (7) sexual and reproductive health education; (8) human immunodeficiency virus prevention activities; and (9) condom promotion, condom use skill building, and demonstration. We found limited evidence of consistent positive impact. Iron supplementation reduced iron-deficiency anemia and raised serum ferritin levels. Promotion of physical activity lowered blood pressure and reduced weight gain. Sexual and reproductive health and human immunodeficiency virus interventions improved adolescent communication with adults but did not influence behavioral outcomes. Countries should consider locally relevant and proven interventions to be offered alongside the HPV vaccine. Copyright © 2015 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

Macroautophagy (or autophagy) is a catabolic cellular process that is both homeostatic and stress adaptive. Normal cells rely on basal levels of autophagy to maintain cellular integrity (via turnover of long-lived proteins and damaged organelles) and increased levels of autophagy to buoy cell survival during various metabolic stresses (via nutrient and energy provision through lysosomal degradation of cytoplasmic components). Autophagy can function in both tumor suppression and tumor progression, and is under investigation in clinical trials as a novel target for anticancer therapy. However, its role in cancer pathogenesis has yet to be fully explored. In particular, it remains unknown whether in vitro observations will be applicable to human cancer patients. Another outstanding question is whether there exists tumor-specific selection for alterations in autophagy function. In this review, we survey reported mutations in autophagy genes and key autophagy regulators identified in human tumor samples and summarize the literature regarding expression levels of autophagy genes and proteins in various cancer tissues. Although it is too early to draw inferences from this collection of in vivo studies of autophagy-related alterations in human cancers, their results highlight the challenges that must be overcome before we can accurately assess the scope of autophagy's predicted role in tumorigenesis.

There are no large hydraulic structures in Qishan River cause the less human interference than other major river in Taiwan. However, the aquatic habitats still suffer disturbance from the discharge changes greatly between wet and drought season, and Jiaxian Weir and Yuemei Weir draw surplus water from Qishan River to Nanhua Reservoir and Agongdian Reservoir respectively. The weir operation rule doesn't clear define how much environmental flow should be preserved for maintaining downstream ecological environment. Hence, the study proposes a process for evaluating environmental flow under considering impact on human well-being and ecosystems sustainability. Empirical formula, hydrological, hydraulic and habitat methodologies were used to propose the environmental flow alternatives. Next, water allocation model and Habitat model were used to analysis the impact of environment flow alternatives on human well-being and ecosystems sustainability. The results show the suggested environmental flow in Qishan River is estimated by MAF10%. The environmental flow is between 8.03 10.83 cms during wet season and is between 1.07 1.44cms during wet season. The simulation results also provide the evidence from diverse aspect to help different authorities realized what they get and lose. The information can advance to reach a consensus during negotiations with different authorities and help decision maker make decisions.

The concept of toxicovigilance encompasses the active detection, validation and follow-up of clinical adverse events related to toxic exposures in human beings. Poison centers are key players in this function as poisoning statistics are essential to define the cause, incidence and severity of poisonings occurring in the general population. In addition, the systematic search for unexpected shifts in the recorded causes of poisonings, e.g., following the introduction of a new product, or change in the formulation or recommended use of an old product, allows for a rapid detection of potential adverse health consequences and the implementation of preventive or corrective measures. However, toxicovigilance is genuinely a medical and not only a statistical approach of human toxicity issues. In contrast to epidemiology, toxicovigilance is based on the in-depth medical assessment of acute or chronic intoxications on an individual basis, which requires detailed information that poison centers can rarely obtain via emergency telephone calls and that epidemiologists cannot collect or process. Validation of this medical information must primarily be based on toxicological expertise to help identify causal links between otherwise unexplained pathological conditions and documented toxic exposures. Thus, toxicovigilance can contribute to hazard identification and risk assessment by providing medically validated data which are often overlooked in the process of risk assessment. So far, very few structured toxicovigilance systems have been set up and hopefully national and international initiatives will bridge this gap in our knowledge of the toxicity of many chemicals and commercial products in human beings

Temperature and environmental effects, particularly endocrine disrupters and EMF radiations, are actively investigated in human and non-human reproduction experimental models. Sensitivity and specificity of the different cell types of the testes seminiferous tubules in animals and in human are evaluated, showing a specific responsiveness of spermatogonia (SPG) and resting pachytene spermatocytes (SPC). At 32 o C the 24 h short-term cultures of biopsies of normal human testis show an expected low occurrence of apoptotic SPG (1 %) that increases to 3,4 % in peer samples exposed to VDT for the same period, with the appearance of apoptotic SPC (4,6 %). In samples from a thermically-impaired testis of the same subject the apoptotic occurrence of SPG is 2,6 % with 15,4 % for SPC after 24 h cultures. After 24 h exposure to VDT the apoptotic score is 7,6 % for SPG and 18,5 % for SPC in thermically impaired peer samples. With EMF-bioshields the apoptotic score for SPG is 0,8 % in normal 2,2 % for SPG and 13,8 % for SPC in T-impaired peer-samples. NMRS of the cultures fluids show a proportional production of lactate, corresponding to the different degrees of histopathological impairment of the samples. IVOS (Integrated Visual Optic System) analysis of sperm samples from thermically-impaired, not-repaired and repaired testes exposed to VDT shows sensible variations on straightness (STR), linearity (LIN) and lateral head displacement (LHD) parameters. To evaluate the thermic and non-thermic potential bioeffects of VDT on human spermatogenesis the specificity, the sensitivity and the reproducibility of the biological models on one side and the specificity of the methodologies on the other side must be provided.

Over the past decade, there has been a growing openness about the importance of human factors in forensic work. However, most of it focused on cognitive bias, and neglected issues of workplace wellness and stress. Forensic scientists work in a dynamic environment that includes common workplace pressures such as workload volume, tight deadlines, lack of advancement, number of working hours, low salary, technology distractions, and fluctuating priorities. However, in addition, forensic scientists also encounter a number of industry-specific pressures, such as technique criticism, repeated exposure to crime scenes or horrific case details, access to funding, working in an adversarial legal system, and zero tolerance for "errors". Thus, stress is an important human factor to mitigate for overall error management, productivity and decision quality (not to mention the well-being of the examiners themselves). Techniques such as mindfulness can become powerful tools to enhance work and decision quality. © 2017 American Academy of Forensic Sciences.
Would a "medicalization" of love be a "good" or "bad" form of medicalization? In discussing this question, Earp, Sandberg, and Savulescu primarily focus on the potential positive and negative consequences of turning love into a medical issue. But it can also be asked whether there is something intrinsically regrettable about medicalizing love. It is argued here that the medicalization of love can be seen as an "evaluative category mistake": it treats a core human value (love) as if it were mainly a means to other ends (viz. physical health and hedonic well-being). It is also argued that Earp et al's closing argument (that a scientific perspective on love actually adds more value to love) can be seen as involving another evaluative category mistake: it treats an object of desire and practical interest (namely, love) as if it mainly were an object of scientific contemplation and theoretical interest. It is concluded that, to relate love to health and well-being in a more satisfying way, we should construe the latter two in broader ways, whereby love is itself a component or element of human flourishing.
Central to the attempt to develop a biosemiotics has been the discussion of what it means to be scientific. In Marcello Barbieri's latest argument for leaving Peircean biosemiotics and creating an alternative code-biology the definition of what it means to be scientific plays a major role. For Barbieri "scientific knowledge is obtained by building machine-like models of what we observe in nature". Barbieri interestingly claims that - in combination with the empirical and experimental basis - mechanism is virtually equivalent to the scientific method. The consequences of this statement seem to be that the optimal type of knowledge science can produce about living system is to model them as machines. But the explicit goal of a Peircean semiotically based biosemiotics is (also) to model living systems as cognitive and communicative systems working on the basis of meaning and signification. These two concepts are not part of the mechanistic models of natural science today, not even of cognitive science. Barbieri tries to solve this problem by introducing a new concept of biological meaning that is separate from the Peircean biosemiotics and then add Peirce's semiotics on top. This article argues why this view is inconsistent on the grounds that Peirce's semiotic paradigm only gives meaning in its pragmaticist conception of a fallibilist view of science, which again is intrinsic connected to its non-mechanistic metaphysics of Tychism, Synechism and Agapism. The core of the biosemiotic enterprise is to establish another type of trans- and interdisciplinary wissenschaft than the received view of "science". Copyright © 2015. Published by Elsevier Ltd.

There are many tubular or rod-shaped organs and tissues within the human body. A miniature medical implant that wraps around such a biological structure can monitor or modulate its function. In order to provide the wrap-around implant with power, a solenoidal coil coupled wirelessly with a planar coil outside the human body can be used. Unfortunately, there is a serious practical problem that this configuration cannot be realized easily because the implantable solenoidal coil cannot be positioned around the tubular biological structure unless either the structure or the coil is cut and reconnected, which is impermissible in most cases. In addition, when a planner exterior coil is used for wireless power transfer and communication, its maximum magnetic coupling with the implanted solenoidal coil is achieved when the tubular structure is perpendicular to the surface of the body. However, in human anatomy, most tubular/rod structures are oriented horizontally. In order to solve these problems, we present a new flexible coil for the class of wrapped-around implantable devices. Our multilayer coil has specially designed windings in cross patterns. The new coil can be made conveniently in high precision at low cost on a flat substrate using the same technology for making the flexible multilayer printed circuit boards along with miniature sensors and electronic circuits. This allows the implant to be made in a flat form and then wrapped around the biostructure during surgery. We present the design of this new coil, perform theoretical analysis with respect to its wireless power transfer efficiency, discuss the effects of coil parameters, and conduct experiments using constructed miniature prototypes. Our results confirm the validity of the new coil.

Worldwide, nuclear fission is used to produce electricity. On the one hand, the low emission of CO_2 is often mentioned as an advantage of this technology. On the other hand, warnings about the dangers of nuclear fission are mentioned. Consequently, an overview about the dangers of ionizing radiation to human beings as well as animals and the environment is important. However, the focus will be on possible health effects for humans with regards to nuclear power plants. In nuclear power plants, both natural types of radiation and artificially produced radiation occur. During normal operation, it is possible that small quantities of this ionizing radiation are released to the environment. In case of nuclear disasters or faults during decommissioning and dismantling processes the consequences of thereby emitted quantities can be even more severe. Reference nuclides vary by reactor type, operating stage and respective incident. At the beginning, different types of radiation and their characteristics and effects on the affected organism are explained. Sensitive organs are emphasized in this context. The individual risk is determined by numerous factors and therefore cannot be predicted. Based on scientific studies and medical publications the hazards of ionizing radiation are compiled. Effects of high exposure of ionizing radiation are well-investigated. Scientists are still divided over the connection between several diseases and the exposure to low doses of ionizing radiation. For this reason, the positions of different international organizations are critically contrasted in this study.

Human milk is the ideal food for human infants. However, some infants will be in situations wherein there is insufficient human milk to meet their needs. This article addresses formal breast milk donation (donor milk) and informal sharing of breast milk. Healthcare providers are likely to encounter families who access milk by informal breast milk sharing or cross-nursing. Both practices rely heavily on receiving human milk from women who are potentially unscreened for disease, medication, and illicit substances. Therefore, it is important for perinatal nurses to have adequate information to be able to inform these families of the risks and benefits of breast milk sharing. Two case exemplars are provided to illustrate the nuances of informal milk sharing. Implications for practice include providing families with information on health history and laboratory screening as well as safe milk-handling practices.

The ecosystem services concept is seen by many as a useful paradigm to support decision-making at the complex interface between science, policy and practice. However, to be successful, it requires a strong willingness for collaboration and joint understanding. In support of this aspiration, OPPLA is being developed as a web portal to enable European communities to better manage ecosystems for human well-being and livelihoods. OPPLA will provide access to a variety of online resources such as tools, case studies, lessons learned, videos, manuals and training and educational materials. It will also provide expert forums and spaces for discussions between researchers, practitioners and decision makers. Hence a critical aspect of the success of OPPLA is the co-evolution of communities of practice. An example of a community of practice is the recently launched Ecosystem Services Community - Scotland (ESCom-Scotland; escomscotland.wordpress.com). ESCom-Scotland aims to support better management of Scotland's natural resources by helping to establish a community of practice between individuals and groups involved in the science, policy and practice behind sustainable ecosystem management. It aspires to encourage the sharing of ideas, increase collaboration and to initiate a support network for those engaging with the ecosystem services concept and it will use the OPPLA resources to support these activities. OPPLA is currently at the developmental stage and was instigated by two large European Commission funded research projects: OPERAs (www.operas-project.eu) and OpenNESS (www.openness-project.eu), with a combined budget of ca. €24m. These projects aim to improve understanding of how ecosystem services contribute to human well-being in different social-ecological systems. Research will establish whether, how and under what conditions the ecosystem services concept can move beyond the academic domain towards practical implementation in support of sustainable ecosystem

A 19-year-old woman with a history of juvenile laryngeal papillomatosis (JLP), treated since childhood with multiple resections, was admitted with symptoms of pneumonia. A chest X-ray and CAT-scan revealed multiple lung cysts and a bronchoalveolar lavage detected human papilloma virus 11. The patient responded well to antibiotics. A body plethysmography showed small lung volumes and low diffusion capacity for carbon monoxide, but normal volume diffusion capacity divided by alveolar volume. Pulmonary cystic disease should be considered when patients with JLP have symptoms of pneumonia.

Intravenous infusion of fructose has been shown to enhance reduced form of nicotinamide adenine dinucleotide reoxidation and, thereby, to enhance the metabolism of ethanol. In the current study, the effect of fructose infusion on first-pass metabolism of ethanol was studied in human volunteers....... A significantly higher first-pass metabolism of ethanol was obtained after administration of fructose in comparison with findings for control experiments with an equimolar dose of glucose. Because fructose is metabolized predominantly in the liver and can be presumed to have virtually no effects in the stomach...

A growing number of quantitative studies have investigated the potential benefits of outdoor blue spaces (lakes, rivers, sea, etc) and human health, but there is not yet a systematic review synthesizing this evidence. To systematically review the current quantitative evidence on human health and well-being benefits of outdoor blue spaces. Following PRISMA guidelines for reporting systematic reviews and meta-analysis, observational and experimental quantitative studies focusing on both residential and non-residential outdoor blue space exposure were searched using specific keywords. In total 35 studies were included in the current systematic review, most of them being classified as of "good quality" (N=22). The balance of evidence suggested a positive association between greater exposure to outdoor blue spaces and both benefits to mental health and well-being (N=12 studies) and levels of physical activity (N=13 studies). The evidence of an association between outdoor blue space exposure and general health (N=6 studies), obesity (N=8 studies) and cardiovascular (N=4 studies) and related outcomes was less consistent. Although encouraging, there remains relatively few studies and a large degree of heterogeneity in terms of study design, exposure metrics and outcome measures, making synthesis difficult. Further research is needed using longitudinal research and natural experiments, preferably across a broader range of countries, to better understand the causal associations between blue spaces, health and wellbeing.

Full Text Available We have entered the 21st century that is popularly known as the era of the development of modern science and technology. Philosophy provides naming for contemporary era as postmodern era. But do we suddenly come to this day and age? No! Because humans are homo viator, persona that does pilgrimage in history, space and time. Philosophy has expanded periodically in the long course of history. Since the days of classical antiquity, philosophy comes with a patterned metaphysical paradigm. This paradigm survives very long in the stage history of philosophy as maintained by many philosophers who hold fast to the philosophical-epistemic claim that philosophy should be (das sollen metaphysical. Classical Greek philosopher, Aristotle was a philosopher who claims metaphysics as the initial philosophy. Then, Immanuel Kant, Hegel, Heidegger, Marx even Habermas offer appropriate shades of metaphysical philosophy versus spirit of the age. Modern philosophers offer a new paradigm in the way of doing philosophy. The new spirit of modern philosophers declared as if giving criticism on traditional western metaphysics (since Aristotle that are considered irrelevant. This paper intends to show the argument between traditional metaphysical and modern philosophers who criticize metaphysics. The author will make a philosophical synthesis to obtain enlightenment to the position of human beings in the space of time. Using the method of Hegelian dialectic (thesis-antiteses-synthesis, this topic will be developed and assessed in accordance with the interests of this paper.

It is argued that the current policy of the British Medical Association (BMA) on conscientious objection is not aligned with recent human rights developments. These grant a right to conscientious objection to doctors in many more circumstances than the very few recognised by the BMA. However, this wide-ranging right may be overridden if the refusal to accommodate the conscientious objection is proportionate. It is shown that it is very likely that it is lawful to refuse to accommodate conscientious objections that would result in discrimination of protected groups. It is still uncertain, however, in what particular circumstances the objection may be lawfully refused, if it poses risks to the health and safety of patients. The BMA's policy has not caught up with these human rights developments and ought to be changed. Published by the BMJ Publishing Group Limited.

Biobanks are essential tools for facilitating biomedical research, because they provide collections of human tissue linked with personal information. There is still little understanding of the underlying reasons why people participate in biobanking in the increasingly commercialised and internationalised biomedical research environment. This paper reports the results of an Australia-wide telephone survey. The paper analyses the types of obligations that members of the public may wish to see incorporated in biobank benefit sharing arrangements and the extent to which their views might be influenced by underlying norms of sharing behaviour. Latent class analysis of the dataset reveals three distinct classes of respondents. We link one of these with the norm of reciprocity, one with the norm of social responsibility. The third is not clearly linked with any one norm of sharing behaviour. The implications of these findings on biobank benefit sharing arrangements are discussed.
Full Text Available As in many other continents, neotropical ecosystems are impacted by the construction of reservoirs. These artificial ecosystems change considerably the natural terrestrial and aquatic ecosystems and their biodiversity. The multiple uses of reservoirs promote benefits for the human beings in terms of economic development, income, jobs and employment. Services of reservoirs are important assets for the regional ecosystem. Evaluation of ecosystem services produced by artificial reservoirs, are new challenges to the understanding of the cost/benefit relationships of reservoir construction in the neotropics. Regulating and other services promoted by reservoirs lead to new trends for "green technology" and the implementation of ecohydrological and ecotechnological developments. This approach can be utilized with better success as a substitute for the usual impact/benefit evaluation of the reservoirs. Better and diversified services can be achieved with "green technology" applied to the construction.

Diffraction enhanced imaging (DEI) with edge enhancement is suitable for the observation of weakly absorbing objects. The potential ability of the DEI was explored for displaying the microanatomy and pathology of human eyeball in this work. The images of surgical specimens from malignant intraocular tumor of hospitalized patients were taken using the hard X-rays from the topography station of Beamline 4W1A at Beijing Synchrotron Radiation Facility (BSRF). The obtained radiographic images were analyzed in correlation with those of pathology. The results show that the anatomic and pathologic details of intraocular tumors in human beings can be observed clearly by DEI for the first time, with good visualization of the microscopic details of eyeball ring such as sclera, choroid and other details of intraocular organelles. And the best resolution of DEI images reaches up to the magnitude of several tens of μm. The results suggest that it is capable of exhibiting clearly the details of intraocular tumor using DEI method. (authors)
Full Text Available The recently endorsed Sustainable Development Goals (SDGs agenda unanimously agrees on the need to focus on inclusive development, the importance of eradicating extreme poverty and managing often complex human well-being impacts of rapid urban growth. Sustainable and inclusive urbanisation will accelerate progress towards the SDGs and contribute to eradicating extreme poverty. In tropical delta regions, such as the Ganges Brahmaputra Meghna delta region, urban growth and resulting intra-urban inequalities are accelerated by the impact of environmental and climate change. In this context, the present study uses the 2010 Household Income and Expenditure Survey to analyse the extent of wealth-based inequalities in human well-being in the urban delta region and the determinants of selected welfare measures. The results suggest that the extent of intra-urban inequalities is greatest in educational attainment and access to postnatal healthcare and relatively low in the occurrence of gastric disease. The paper concludes by providing policy recommendations to reduce increasing wealth inequalities in urban areas, thus contributing to sustainable development of the region.
The potential benefits of sharing data so outweigh its costs that investigators should be required to include plans for sharing data as part of their grant proposals, according to recommendations issued recently by the Committee on National Statistics (CNSTAT) of the National Research Council (NRC).In their report Sharing Research Data, CNSTAT also recommended that “Journals should give more emphasis to reports of secondary analyses and to replications,” provided that the original collections of data receive full credit. In addition, “Journal editors should require authors to provide access to data during the peer review process.”

Influential demographic projections suggest that the global human population will stabilize at about 9-10 billion people by mid-century. These projections rest on two fundamental assumptions. The first is that the energy needed to fuel development and the associated decline in fertility will keep pace with energy demand far into the future. The second is that the demographic transition is irreversible such that once countries start down the path to lower fertility they cannot reverse to higher fertility. Both of these assumptions are problematic and may have an effect on population projections. Here we examine these assumptions explicitly. Specifically, given the theoretical and empirical relation between energy-use and population growth rates, we ask how the availability of energy is likely to affect population growth through 2050. Using a cross-country data set, we show that human population growth rates are negatively related to per-capita energy consumption, with zero growth occurring at ∼13 kW, suggesting that the global human population will stop growing only if individuals have access to this amount of power. Further, we find that current projected future energy supply rates are far below the supply needed to fuel a global demographic transition to zero growth, suggesting that the predicted leveling-off of the global population by mid-century is unlikely to occur, in the absence of a transition to an alternative energy source. Direct consideration of the energetic constraints underlying the demographic transition results in a qualitatively different population projection than produced when the energetic constraints are ignored. We suggest that energetic constraints be incorporated into future population projections.

Salivary alpha-amylase (sAA) has been proposed as a sensitive non-invasive biomarker for stress-induced changes in the body that reflect the activity of the sympathetic nervous system. Though several experiments have been conducted to determine the validity of this salivary component as a reliable stress marker in human subjects, the effect of stress induced changes on sAA level in different age groups is least studied. This article reports the activity of sAA in human subjects of different age groups subjected to psychological stress induced through stressful video clip. Differences in sAA level based on sex of different age groups under stress have also been studied. A total of 112 subjects consisting of both the male and female subjects, divided into two groups on basis of age were viewed a video clip of corneal transplant surgery as stressor. Activity of sAA from saliva samples of the stressed subjects were measured and compared with the activity of the samples collected from the subjects before viewing the clip. The age ranges of subjects were 18-25 and 40-60 years. The sAA level increased significantly in both the groups after viewing the stressful video. The increase was more pronounced in the younger subjects. The level of sAA was comparatively more in males than females in the respective groups. No significant change in sAA activity was observed after viewing the soothed video clip. Significant increase of sAA level in response to psychological stress suggests that it might act as a reliable sympathetic activity biochemical marker in different stages of human beings.

Human embryonic stem cells have shown tremendous potential in regenerative medicine, and the recent progress in haploid embryonic stem cells provides new insights for future applications of embryonic stem cells. Disruption of normal fertilized embryos remains controversial; thus, the development of a new source for human embryonic stem cells is important for their usefulness. Here, we investigated the feasibility of haploid and diploid embryo reconstruction and embryonic stem cell derivation using microsurgically repaired tripronuclear human zygotes. Diploid and haploid zygotes were successfully reconstructed, but a large proportion of them still had a tripolar spindle assembly. The reconstructed embryos developed to the blastocyst stage, although the loss of chromosomes was observed in these zygotes. Finally, triploid and diploid human embryonic stem cells were derived from tripronuclear and reconstructed zygotes (from which only one pronucleus was removed), but haploid human embryonic stem cells were not successfully derived from the reconstructed zygotes when two pronuclei were removed. Both triploid and diploid human embryonic stem cells showed the general characteristics of human embryonic stem cells. These results indicate that the lower embryo quality resulting from abnormal spindle assembly contributed to the failure of the haploid embryonic stem cell derivation. However, the successful derivation of diploid embryonic stem cells demonstrated that microsurgical tripronuclear zygotes are an alternative source of human embryonic stem cells. In the future, improving spindle assembly will facilitate the application of triploid zygotes to the field of haploid embryonic stem cells. PMID:23255130

Social learning is a powerful method for cultural propagation of knowledge and skills relying on a complex interplay of learning strategies, social ecology and the human propensity for both learning and tutoring. Social learning has the potential to be an equally potent learning strategy for artificial systems and robots in specific. However, given the complexity and unstructured nature of social learning, implementing social machine learning proves to be a challenging problem. We study one particular aspect of social machine learning: that of offering social cues during the learning interaction. Specifically, we study whether people are sensitive to social cues offered by a learning robot, in a similar way to children’s social bids for tutoring. We use a child-like social robot and a task in which the robot has to learn the meaning of words. For this a simple turn-based interaction is used, based on language games. Two conditions are tested: one in which the robot uses social means to invite a human teacher to provide information based on what the robot requires to fill gaps in its knowledge (i.e. expression of a learning preference); the other in which the robot does not provide social cues to communicate a learning preference. We observe that conveying a learning preference through the use of social cues results in better and faster learning by the robot. People also seem to form a “mental model” of the robot, tailoring the tutoring to the robot’s performance as opposed to using simply random teaching. In addition, the social learning shows a clear gender effect with female participants being responsive to the robot’s bids, while male teachers appear to be less receptive. This work shows how additional social cues in social machine learning can result in people offering better quality learning input to artificial systems, resulting in improved learning performance.

The close relationship between human health, performance, well-being and the thermal environment is obvious. Nevertheless, most studies of climate and climate change impacts show amazing shortcomings in the assessment of the environment. Populations living in different climates have different susceptibilities, due to socio-economic reasons, and different customary behavioural adaptations. The global distribution of risks of hazardous thermal exposure has not been analysed before. To produce maps of the baseline and future bioclimate that allows a direct comparison of the differences in the vulnerability of populations to thermal stress across the world. The required climatological data fields are obtained from climate simulations with the global General Circulation Model ECHAM4 in T106-resolution. For the thermo-physiologically relevant assessment of these climate data a complete heat budget model of the human being, the 'Perceived Temperature' procedure has been applied which already comprises adaptation by clothing to a certain degree. Short-term physiological acclimatisation is considered via Health Related Assessment of the Thermal Environment. The global maps 1971-1980 (control run, assumed as baseline climate) show a pattern of thermal stress intensities as frequencies of heat. The heat load for people living in warm-humid climates is the highest. Climate change will lead to clear differences in health-related thermal stress between baseline climate and the future bioclimate 2041-2050 based on the 'business-as-usual' greenhouse gas scenario IS92a. The majority of the world's population will be faced with more frequent and more intense heat strain in spite of an assumed level of acclimatisation. Further adaptation measures are crucial in order to reduce the vulnerability of the populations. This bioclimatology analysis provides a tool for various questions in climate and climate change impact research. Considerations of regional or local scale require climate
Full Text Available Humans are thought to possess a unique proclivity to share with others--including strangers. This puzzling phenomenon has led many to suggest that sharing with strangers originates from human-unique language, social norms, warfare and/or cooperative breeding. However, bonobos, our closest living relative, are highly tolerant and, in the wild, are capable of having affiliative interactions with strangers. In four experiments, we therefore examined whether bonobos will voluntarily donate food to strangers. We show that bonobos will forego their own food for the benefit of interacting with a stranger. Their prosociality is in part driven by unselfish motivation, because bonobos will even help strangers acquire out-of-reach food when no desirable social interaction is possible. However, this prosociality has its limitations because bonobos will not donate food in their possession when a social interaction is not possible. These results indicate that other-regarding preferences toward strangers are not uniquely human. Moreover, language, social norms, warfare and cooperative breeding are unnecessary for the evolution of xenophilic sharing. Instead, we propose that prosociality toward strangers initially evolves due to selection for social tolerance, allowing the expansion of individual social networks. Human social norms and language may subsequently extend this ape-like social preference to the most costly contexts.

Full Text Available In this article, we address the question basic education as a right of every human being. To do this, we will use empirical data as well as literature review in the national and international levels. First, the article is talking about an ideal model of quality basic education for all, making general contours of the world stage, to specifically enter the state of education in Brazil. We discuss the text a study of the various existing regulatory provisions in Brazil that deal with the need to ensure quality basic education in an inclusive way that meets the different needs of students in different regions of our country, and thus try to find solutions to the problems we face when trying to bring quality education to all. Finally, we will address issues related to guaranteeing the right to education at the international level, pointing out the legal provisions that guarantee this right and approach the principle of human dignity as a means for the realization of this right.

We theorize that people's social class affects their appraisals of others' motivational relevance-the degree to which others are seen as potentially rewarding, threatening, or otherwise worth attending to. Supporting this account, three studies indicate that social classes differ in the amount of attention their members direct toward other human beings. In Study 1, wearable technology was used to film the visual fields of pedestrians on city streets; higher-class participants looked less at other people than did lower-class participants. In Studies 2a and 2b, participants' eye movements were tracked while they viewed street scenes; higher class was associated with reduced attention to people in the images. In Study 3, a change-detection procedure assessed the degree to which human faces spontaneously attract visual attention; faces proved less effective at drawing the attention of high-class than low-class participants, which implies that class affects spontaneous relevance appraisals. The measurement and conceptualization of social class are discussed. © The Author(s) 2016.

It was studied the influence of chemical structures and molecular weight in the distribution of several iminodiacetic acid N-derivatives and to determine the potential use of these radiopharmaceuticals in humans. The study was performed with the following derivatives: N-(2,6 dimetyphenylcarbamoylmethy) iminodiacetic acid, N(2.6 dietylphenyl-carbamoylmethy) iminodiacetic acid, N-(2,6 diisopropylphenylcarbamoylmethy) iminodiacetic acid and the previously unknown N-derivative N-(2,6 diisopropyl, phenylcarbamoylethyl) iminodiacetic aced. These were sinthesized by a modified procedure by MITTA et al. and controlled by NMR, mass spectrometry, elemental composition and also toxicity pirogens, lethal dose and the chelate's radiochemical dose were determined. Liver gallbladder, intestinal and renal kinetics were studied in mice. In order to evaluate the metabolic pathways of the radiopharmaceuticals, the content of gallbladder and the urine were reinjected. Plasma kinetics and the plasmatic half life was determined by extracorporeal circulation in Wistar rats. For the use in human beings, test were carried out in different branches of nuclear medicine, in normal volunteers and carriers of different pathologic disorders. The patients were divided into four groups: acute and chronic cholecystitis, cirrhosis and jaundice. It was obtained the liver/heart activity ratio and estimated the appearance times of the intrahepatic ducts, gallbladder, duodenum and renal persistence. (M.E.L.) [es

knowledge sharing is to ensure that the exchange is seen as equitable for the parties involved, and by viewing the problems of knowledge sharing as motivational problems situated in different organizational settings, the paper explores how knowledge exchange can be conceptualized as going on in four...... distinct situations of exchange denominated organizational exchange yielding extrinsic rewards, organizational exchange yielding intrinsic rewards, financial exchange, and social exchange. The paper argues that each situation of exchange has distinct assumptions about individual behaviour...... and the intermediaries regulating the exchange, and facilitating knowledge sharing should therefore be viewed as a continuum of practices under the influence of opportunistic behaviour, obedience or organizational citizenship behaviour.

Why do members of the public share some scientific findings and not others? What can scientists do to increase the chances that their findings will be shared widely among nonscientists? To address these questions, we integrate past research on the psychological drivers of interpersonal communication with a study examining the sharing of hundreds of recent scientific discoveries. Our findings offer insights into (i) how attributes of a discovery and the way it is described impact sharing, (ii)...

By 2050, 70% of the world's population will live in urban areas. In many cases urbanization reduces the richness and abundance of native species. Living in highly modified environments with fewer opportunities to interact directly with a diversity of native species may adversely affect residents' personal well-being and emotional connection to nature. We assessed the personal well-being, neighborhood well-being (a measure of a person's satisfaction with their neighborhood), and level of connection to nature of over 1000 residents in 36 residential neighborhoods in southeastern Australia. We modeled these response variables as a function of natural features of each neighborhood (e.g., species richness and abundance of birds, density of plants, and amount of vegetation cover) and demographic characteristics of surveyed residents. Vegetation cover had the strongest positive relations with personal well-being, whereas residents' level of connection to nature was weakly related to variation in species richness and abundance of birds and density of plants. Demographic characteristics such as age and level of activity explained the greatest proportion of variance in well-being and connection to nature. Nevertheless, when controlling for variation in demographic characteristics (examples were provided above), neighborhood well-being was positively related to a range of natural features, including species richness and abundance of birds, and vegetation cover. Demographic characteristics and how well-being was quantified strongly influenced our results, and we suggest demography and metrics of well-being must be considered when attempting to determine relations between the urban environment and human well-being. © 2011 Society for Conservation Biology.

Full Text Available Continued monitoring of environmental chemicals is important for understanding human exposure and potentially related health risk(s. Cinar et al.  contribute to our knowledge on infant exposures to environmental chemicals in breast milk. However, the messages implicit both in the title and in the paper itself are unnecessarily alarming and are likely to be interpreted by mothers and health professionals as indicating that breast feeding is generally unsafe in certain regions of Turkey. For example, the conclusion that “Rural area also may not be safe for breastfeed babies” is based on an evaluation of 90 women, without regard to differences in their potential exposure patterns; lifestyle, smoking status, occupation, body mass index, or residential history. It is unclear whether these women are in any way representative of rural areas in Turkey, or rural areas in general. Further, the authors do not provide reference values with which to compare the levels of metals that they report, and the values that they report for several metals are 10-1000 times higher than the levels reported in other studies (although it is unclear whether they have reported the levels with correct units; the authors note that the mothers’ levels were lower than recommended levels of 10 microg/L (Hg and 30 microg/L (Pb while describing the mothers’ reported levels as being in the low parts per million range [Table 4]. Only under exceptional circumstances including clinical treatment with certain pharmaceuticals or in cases of accidental poisonings have the occurrence of chemicals in breast milk resulted in a recommendation to avoid breastfeeding. Otherwise, studies have shown that breastfeeding can counter subtle adverse effects associated with in utero maternal exposure to hazardous substances . Numerous studies demonstrate the superiority of breastfeeding in lowering risk of adverse health outcomes when compared to formula-fed infants. Thus, the World

Measures of socio-economic impacts of conservation interventions have largely been restricted to externally defined indicators focused on income, which do not reflect people's priorities. Using a holistic, locally grounded conceptualization of human well-being instead provides a way to understand the multi-faceted impacts of conservation on aspects of people's lives that they value. Conservationists are engaging with well-being for both pragmatic and ethical reasons, yet current guidance on how to operationalize the concept is limited. We present nine guiding principles based around a well-being framework incorporating material, relational and subjective components, and focused on gaining knowledge needed for decision-making. The principles relate to four key components of an impact evaluation: (i) defining well-being indicators, giving primacy to the perceptions of those most impacted by interventions through qualitative research, and considering subjective well-being, which can affect engagement with conservation; (ii) attributing impacts to interventions through quasi-experimental designs, or alternative methods such as theory-based, case study and participatory approaches, depending on the setting and evidence required; (iii) understanding the processes of change including evidence of causal linkages, and consideration of trajectories of change and institutional processes; and (iv) data collection with methods selected and applied with sensitivity to research context, consideration of heterogeneity of impacts along relevant societal divisions, and conducted by evaluators with local expertise and independence from the intervention. © 2015 The Authors.

Conservationists are increasingly engaging with the concept of human well-being to improve the design and evaluation of their interventions. Since the convening of the influential Sarkozy Commission in 2009, development researchers have been refining conceptualizations and frameworks to understand and measure human well-being and are starting to converge on a common understanding of how best to do this. In conservation, the term human well-being is in widespread use, but there is a need for guidance on operationalizing it to measure the impacts of conservation interventions on people. We present a framework for understanding human well-being, which could be particularly useful in conservation. The framework includes 3 conditions; meeting needs, pursuing goals, and experiencing a satisfactory quality of life. We outline some of the complexities involved in evaluating the well-being effects of conservation interventions, with the understanding that well-being varies between people and over time and with the priorities of the evaluator. Key challenges for research into the well-being impacts of conservation interventions include the need to build up a collection of case studies so as to draw out generalizable lessons; harness the potential of modern technology to support well-being research; and contextualize evaluations of conservation impacts on well-being spatially and temporally within the wider landscape of social change. Pathways through the smog of confusion around the term well-being exist, and existing frameworks such as the Well-being in Developing Countries approach can help conservationists negotiate the challenges of operationalizing the concept. Conservationists have the opportunity to benefit from the recent flurry of research in the development field so as to carry out more nuanced and locally relevant evaluations of the effects of their interventions on human well-being.

Genomic discoveries will increasingly advance the science of medicine. Limited genomic literacy may adversely impact the public's understanding and use of the power of genetics and genomics in health care and public health. In November 2011, a meeting was held by the National Human Genome Research Institute to examine the challenge of achieving genomic literacy for the general public, from kindergarten to grade 12 to adult education. The role of the media in disseminating scientific messages and in perpetuating or reducing misconceptions was also discussed. Workshop participants agreed that genomic literacy will be achieved only through active engagement between genomics experts and the varied constituencies that comprise the public. This report summarizes the background, content, and outcomes from this meeting, including recommendations for a research agenda to inform decisions about how to advance genomic literacy in our society.

The ideal of patient centred medicine remains only partially realised. Within modern Western society, the highly individualistic culture and religious decline linked with medicine's reluctance to relinquish an outmoded form of scientific rationalism can act as reductive influences, stifling conceptual development. Some examples of the recent literature on communication skills in medicine are analysed to discern the underlying philosophy. A rationalist stance invites an examination of the possible nature of rationality. Another example accepts the need to accommodate the emotional and the unconscious. Issues of human suffering with an inherent spiritual dimension seem to remain excluded. The need to move beyond a duality of reason and emotion to embrace the existential and spiritual is suggested as a theoretical prerequisite for developing a more inclusive concept of patient centred medicine, which only then may be realised. Some brief examples are considered of the sort of notions and types of discourse that might effectively inform "teaching" of communication skills.

Juices from the traditional red tomato and a unique tangerine tomato variety are being investigated as health promoting foods in human clinical trials. However, it is unknown how the tangerine and red tomato juices differ in biologically relevant phytochemicals beyond carotenoids. Here liquid-chromatography high-resolution mass spectrometry metabolomics was used to evaluate broadly the similarities and differences in carotenoids and other phytochemicals between red and tangerine tomato juices intended for clinical interventions. This untargeted approach was successful in the rapid detection and extensive characterization of phytochemicals belonging to various compound classes. The tomato juices were found to differ significantly in a number of phytochemicals, including carotenoids, chlorophylls, neutral lipids, and cinnamic acid derivatives. The largest differences were in carotenoids, including lycopene, phytoene, phytofluene, neurosporene, and ζ-carotene. Smaller, but significant, differences were observed in polar phytochemicals, such as chlorogenic acid, hydroxyferulic acid, phloretin-di-C-glycoside, and isopropylmalic acid.

A specialized isotope mass spectrometer for noninvasive diagnostics of Helicobacter pylori infection in human beings based on the carbon-13 isotope breath test has been designed and constructed. Important stages of the work included (i) calculating a low-aberration mass analyzer, (ii) manufacturing and testing special gas inlet system, and (iii) creating a small-size collector of ions. The proposed instrument ensures 13C/12C isotopic ratio measurement to within 1.7‰ (pro mille) accuracy, which corresponds to requirements for a diagnostic tool. Preliminary medical testing showed that the mass spectrometer is applicable to practical diagnostics. The instrument is also capable of measuring isotopic ratios of other light elements, including N, O, B (for BF2+ ions), Ar, Cl, and S.

Thirteen human beings were infested with ticks at Sandynallah and Gudalur of the Nilgiris district and Mottur Suruvakkam of Kancheepuram district of Tamil Nadu from January 2016 to December 2016. The collected ticks were identified as Rhipicephalus haemaphysaloides , Otobius megnini and Hyalomma isaaci. The tick infestation was observed more on the persons working with animals (sheep and goats) than those working in tea estate. The person infested with R. haemaphysaloides revealed erythematous papule (2 mm size) and inflammatory lesion up to 16 days whereas, the people infested with H. isaaci showed continuous itching and irritation for > 6 months and wound formation (0.5 cm) at the biting site. The people infested with O. megnini showed irritation, vomiting sensation and fever.

The author considers the application of natural toxins as arrow poison by Homo sapiens from ancient time till today for hunting and ethnic wars on the example of natives of Asia, Africa, South America and Oceania. Geographic isolation was important determining the spectrum of natural toxin sources and the methods of their application. Cellular and molecular mechanisms of arrow poisons effects are considered in biogeographical context: aconitin and strychnin in Asia, diamphotoxin in Africa, indole alcaloids of plants and steroid alcaloids of amphibian in Central and South America, palytoxin in Oceania islands. High efficiency and selective effect of natural toxins allow to use them as molecular markers in current studies of functional membrane architecture and cellular structures. Great differences in pace of civilization development leads to the co-existence at the beginning of the XXI century ethnic groups that use natural toxins as arrow poison and human beings that use the same toxins in fundamental and applied investigations within international scientific society.

Community Forest Management (CFM) devolves forest management to local communities to achieve conservation and human well-being goals. Yet, the evidence for CFM's impacts is mixed and difficult to interpret because of inadequate attention to rival explanations for the observed empirical patterns....... In a national-scale analysis in Madagascar that carefully considers these rival explanations, we estimate CFM impacts on household living standards, as measured by per capita consumption expenditures. The estimated impact is positive, but small and not statistically different from zero. However, we can...... statistically reject substantial negative impacts (which others have suggested may exist). The estimated impacts vary conditional on household education and proximity to forests: they are more positive and statistically significant for households closer to forest and with more education. To help improve CFM...
The emerging manifesto, center of the essay collection this commentary is part of, points out that primatology is a primate's science and field of endeavor. It is about primates, and constructed and carried out by primates. But the relationships between different primates involved in primatology cannot be described merely as scientific, zoological, or conservatory. A main point emerging from this perspective is that the relationships amongst primates (as scientists and as subjects) are affected by primatologists' experiences outside of academic science and within the cultural schema that we acquire as members of human societies. My contribution focuses on the primatologists and their sometimes discussed, but too often ignored, cultural and ethnic contexts as influences on how they study, think about, and interact with other primates. In our views and bonds with other primates, do national, class, and ethnic factors count? 2010 Wiley-Liss, Inc.
Full Text Available β-cell replacement by allogeneic islet transplantation is a promising approach for patients with type 1 diabetes, but the shortage of organ donors requires new sources of β cells. Islet regeneration in vivo and generation of β-cells ex vivo followed by transplantation represent attractive therapeutic alternatives to restore the β-cell mass. In this paper, we discuss different postnatal cell types that have been envisaged as potential sources for future β-cell replacement therapy. The ultimate goal being translation to the clinic, a particular attention is given to the discrepancies between findings from studies performed in rodents (both ex vivo on primary cells and in vivo on animal models, when compared with clinical data and studies performed on human cells.

Full Text Available That ministry is to be given back to the laity is a laudable proposition. However, the level of development in many township and village communities is still such that a strong leadership and management facilitation role is demanded of the pastor. In such contexts, the pastor is also the only one who is always available for church tasks. The point of departure of this article was that the pastor is primarily a facilitator who assumes the tasks of a leader, a manager and a servant. The Trinitarian office of Christ is taken as model. Christian leadership, as discussed from a systems perspective, is seen as enabling rather than hegemonic. The pastor fulfils the seven leadership functions in order to equip the saints for their Christian service. Church management is redefined as a process which takes place in meaningful collaboration with others, over against the objectification found in conventional definitions which focus on ‘getting things done through people’. This article discussed servant leadership and service provision as the central purpose of Christian leadership.

The Earth's ecosystems have been altered by anthropogenic processes, including land use, harvesting populations, species introductions and climate change. These anthropogenic processes greatly alter plant and animal communities, thereby changing transmission of the zoonotic pathogens they carry. Biodiversity conservation may be a potential win-win strategy for maintaining ecosystem health and protecting public health, yet the causal evidence to support this strategy is limited. Evaluating conservation as a viable public health intervention requires answering four questions: (i) Is there a general and causal relationship between biodiversity and pathogen transmission, and if so, which direction is it in? (ii) Does increased pathogen diversity with increased host biodiversity result in an increase in total disease burden? (iii) Do the net benefits of biodiversity conservation to human well-being outweigh the benefits that biodiversity-degrading activities, such as agriculture and resource utilization, provide? (iv) Are biodiversity conservation interventions cost-effective when compared to other options employed in standard public health approaches? Here, we summarize current knowledge on biodiversity-zoonotic disease relationships and outline a research plan to address the gaps in our understanding for each of these four questions. Developing practical and self-sustaining biodiversity conservation interventions will require significant investment in disease ecology research to determine when and where they will be effective.This article is part of the themed issue 'Conservation, biodiversity and infectious disease: scientific evidence and policy implications'. © 2017 The Author(s).

The field of human genomics has led advances in the sharing of data with a view to facilitating translation of research into innovations for human health. This change in scientific practice has been implemented through new policy developed by many principal investigators, project managers and funders, which has ultimately led to new forms of practice and innovative governance models for data sharing. Here, we examine the development of the governance of data sharing in genomics, and explore some of the key challenges associated with the design and implementation of these policies. We examine how the incremental nature of policy design, the perennial problem of consent, the gridlock caused by multiple and overlapping access systems, the administrative burden and the problems with incentives and acknowledgment all have an impact on the potential for data sharing to be maximized. We conclude by proposing ways in which the scientific community can address these problems, to improve the sustainability of data sharing into the future.

The problems of the haves differ substantially from those of the have-nots. Individuals in developing societies have to fight mainly against infectious and communicable diseases, while in the developed world the battles are mainly against lifestyle diseases. Yet, at a very fundamental level, the problems are the same-the fight is against distress, disability, and premature death; against human exploitation and for human development and self-actualisation; against the callousness to critical concerns in regimes and scientific power centres.While there has been great progress in the treatment of individual diseases, human pathology continues to increase. Sicknesses are not decreasing in number, they are only changing in type.The primary diseases of poverty like TB, malaria, and HIV/AIDS-and the often co-morbid and ubiquitous malnutrition-take their toll on helpless populations in developing countries. Poverty is not just income deprivation but capability deprivation and optimism deprivation as well.While life expectancy may have increased in the haves, and infant and maternal mortality reduced, these gains have not necessarily ensured that well-being results. There are ever-multiplying numbers of individuals whose well-being is compromised due to lifestyle diseases. These diseases are the result of faulty lifestyles and the consequent crippling stress. But it serves no one's purpose to understand them as such. So, the prescription pad continues to prevail over lifestyle-change counselling or research.The struggle to achieve well-being and positive health, to ensure longevity, to combat lifestyle stress and professional burnout, and to reduce psychosomatic ailments continues unabated, with hardly an end in sight.WE THUS REALISE THAT MORBIDITY, DISABILITY, AND DEATH ASSAIL ALL THREE SOCIETIES: the ones with infectious diseases, the ones with diseases of poverty, and the ones with lifestyle diseases.

To solve the problem of global planetary protection, it is necessary to involve enormous forces and means. According to the definition, terraformation is a change in the cosmic body that will bring the atmosphere, temperature and environmental conditions into a state that is necessary for the life of terrestrial animals, plants and people. Therefore, before sending people, for example, to Mars for a permanent settlement, it is necessary first of all there to create a huge complex of preparatory work with the aim, if not completely transform this planet, at least, to organize there the simplest housing for future settlers. At Venus, you can create settlements in "flying" cities with flotilla peculiar "airships" in the upper atmosphere. Terraformation of Mercury can be carried out at latitudes from 70 deg. to the poles, making it suitable localities for human habitation. They should be located below the surface of the planet at a depth of 3-30 m in a zone of comfortable and constant temperatures of about +20° Ð¡. And start terraforming - preferably from the Moon. Such residential complexes should be designed taking into account the need to deploy systems of early detection and counteract the global danger to the Earth by asteroid and comet invasions. That is, the areas of Venus, Mars, Mercury and the Earth - should be equipped with special orbital stations. At these stations, nuclear missile systems for early warning and combating global threats from invasion of asteroids and comets - should be deployed.

The aim of this study in vitro was to compare the share bond strength of the light-cured composite resins Transbond XT (Unitek), with halogen light and argon laser. The Adhesive Remmant Index (ARI) was also investigated. The brackets Dyna lock (3M-UNITEK) were bonded to 75 human premolars, divided into 5 groups (15 each) according to time and the polymerization: Group H20, 15 brackets bonded with halogen light for 20s (10s both sides); Group H40, 15 brackets bonded with halogen light for 40s (20s both sides); Group A40, 15 brackets bonded with argon laser for 40s (20s both sides); Group A20, 15 brackets bonded with argon laser for 20s (10s both sides); Group A10, 15 brackets bonded with argon laser for 10s (5s both sides). The pulpal temperature changes were determined during a polymerization, not exceeding 3,5 deg C. After bonding, the teeth were submitted to a thermo cycled of 700 cycles between 5 deg C and 55 deg C, to simulate the consuming that the light cured composite resin would have in a short space of time. The specimens were then placed in PVC ring and embedded in acrylic resin (Aero-Jet). The tensile bond strength test was performed on an Universal Machine set at a crosshead speed of 1,5 mm/min, and for each rupture we registered a graphic and the best load required in Newtons, was converted to MPa and kgf. The share bond strength showed bigger values for the exposure time of 20 seconds, for the Group bonded for halogen light (H20), 7,45 kgf (7,64 MPa) and for argon laser 7,50 kgf (7,69 MPa); lesser values for the exposure time of 40s for the Group with halogen light (H40), 6,15 kgf (6,30 MPa) and argon laser Group (A40), 6,20 kgf (6,35 MPa) 0; and A10, 4,85 kgf (4,97 MPa). In the ARI Index, only A40 Group showed the 1 Index, with statistical results. In this Group, less than half of the remainder adhesive stayed on the surface of the enamel, conferring specimens failed at the enamel-adhesive interface. The results of the in vitro study demonstrate that

Sharing is a form of human activity as a social being, over resources or spaces. Humans generally define their space according to their psychological and biological needs. However, what if space sharing takes place in an urban scope? The phenomenon of space sharing happens in Kemang area done by two distinct sectors, formal and informal which both are engaged in commercial activities independently. In the study of territory and the behavior settings, the quality of environment can affect the formation of human activities in a space, occurs a phenomenon of space sharing. The researcher will discuss and present a form of the space sharing by the formal and informal sectors in a commercial area through different environmental qualities. In some circumstance, a form of space sharing can increase the value of space and obtain to a shared space, where both sectors mutually take benefits. Otherwise, it leads to an adverse impact in some others. It is clear that differences in the physical environment and social environment have an impact on the formation of space sharing and the value of space in an urban region.

As society strives to transition towards more sustainable development pathways, it is important to properly conceptualize the link between biodiversity (i.e. genes, traits, species and other dimensions) and human well-being (HWB; i.e. health, wealth, security and other dimensions). Here, we explore how published conceptual frameworks consider the extent to which the biodiversity-HWB links are being integrated into public discourse and scientific research and the implications of our findings for sustainable development. We find that our understanding has gradually evolved from seeing the value of biodiversity as an external commodity that may influence HWB to biodiversity as fundamental to HWB. Analysis of the literature trends indicates increasing engagement with the terms biodiversity, HWB and sustainable development in the public, science and policy spheres, but largely as independent rather than linked terms. We suggest that a consensus framework for sustainable development should include biodiversity explicitly as a suite of internal variables that both influence and are influenced by HWB. Doing so will enhance clarity and help shape coherent research and policy priorities. We further suggest that the absence of this link in development can inadvertently lead to a ratcheting down of biodiversity by otherwise well-meaning policies. Such biotic impoverishment could lock HWB at minimum levels or lead to its decline and halt or reverse progress in achieving sustainable development. © 2016 The Authors.

This study analyzes the exposure of the human torso to electromagnetic fields caused by wireless body-mounted or hand-held devices. Because of the frequency and distance ranges from 30-5800 MHz and 10 to 200 mm, respectively, both near-field and far-field effects are considered. A generic body model and simulations of anatomical models are used to evaluate the worst case tissue composition with respect to the absorption of electromagnetic energy. Both standing wave effects and enhanced coupling of reactive near-field components can lead to a specific absorption rate (SAR) increase in comparison to homogeneous tissue. In addition, the exposure and temperature increase of different inner organs is assessed. With respect to compliance testing, the observed SAR enhancement may require the introduction of a multiplication factor for the spatial peak SAR measured in the liquid-filled phantom in order to obtain a conservative exposure assessment. The observed tissue heating at the body surface under adiabatic conditions can be significant, whereas the temperature increase in the inner organs turned out to be negligible for the cases investigated.

Research data should be made readily available. A robust data-sharing plan, led by the principal investigator of the research project, requires considerable administrative and operational resources. Because external support for data sharing is minimal, principal investigators should consider engaging existing institutional information experts, such as librarians and information systems personnel, to participate in data-sharing efforts.
To be efficient, any action undertaken in view of mitigating Greenhouse Gas Emissions requires that the reduction of CO 2 emissions not be confused with energy savings. Indeed, there is strict correlation between the two only if the energy savings achieved lead to fossil fuel savings. If a drastic reduction of greenhouse gas emissions were not mandatory, the conversion of our energy production and use would be less pressing, the known fossil fuel reserves being sufficient to supply humanity for at least one and a half centuries. Keeping these consideration in mind, under the control of its Scientific Council and with the help of partner organizations, STC has elaborated a set of proposals to reduce the economic activity's carbon content without affecting in any fundamental way the life style of the populations concerned while leaving room for economic growth in developing countries. In this sense, the ''Negatep'' scenario put forward by STC is fundamentally different from the ''Negawatt'' type scenarios. The options we recommend are ranked according to their economic efficiency. The index that is conventionally used to compare conceivable solutions is known as the ''cost of carbon avoided'' for a given action. It consists in estimating the additional cost of the action considered in relation to the amount of carbon whose release to the atmosphere is avoided thanks to the action. The index is measured in Euros per metric ton of carbon avoided. Summary of the actions and recommendations put forward by ''Save the Climate'' for energy production and energy efficiency are argued in further detail in this document. (A.L.B.)

Job sharing offers advantages to both employer and employee but it is still uncommon in medicine. Based on the experiences of two psychiatrists sharing a consultant post this article describes some of the problems in obtaining a job share. The most difficult part can be getting an interview, and once a post has been obtained the terms and conditions of service may have to be modified to suit job sharing. Getting on well with your job sharing partner and good communication will not only help o...

The primary purpose of this project is to refocus the current national health care debate. It is the first attempt to provide scientists, health care providers, health care policy makers, politicians, health care payers and public health advocates with a method to improve health care and cut costs through decision-making strategies based primarily on medical standards and secondarily on fiscal considerations. The method for decision-making described in this paper proves more cost-effective and medically sound than current practices. Illness Specific Diagnostic (ISD) tables are introduced as a method to reduce inappropriate use of ionizing radiation in medicine. The use of ISD tables destroys the myth of a single medical standard of care and focuses on the diagnostician as the individual most capable of diagnosing disease(s) in human beings. Additionally, ionizing radiation has been used routinely under the guise that the resulting benefits outweigh the risks involved in a procedure. This dubious tradition is questioned in this document. Attention is drawn to the inappropriate amount of radiation patients receive when ionizing diagnostic tests are performed with marginal or no diagnostic benefit. The results of a pilot study are presented that explicate the reduction of needless radiation to patients and associated reduction of costs that becomes possible in the presence of appropriate scientific medical standards. Ultimately, quality medicine is indeed the most cost-effective medicine possible. The current practice by which the United States Congress issues laws aimed at dictating quality medicine is both desperate and dangerous. Politicians and legislators would be wise to focus their efforts on methodologies that establish standards of care in a scientific manner that does not interfere with medical practice. ISD technology is precisely such a scientific method. It establishes the standard of medical care at the facility from which the ISD tables are generated
Full Text Available In this introductory essay, we explore definitions of the ‘sharing economy’, a concept indicating both social (relational, communitarian and economic (allocative, profit-seeking aspects which appear to be in tension. We suggest combining the social and economic logics of the sharing economy to focus on the central features of network enabled, aggregated membership in a pool of offers and demands (for goods, services, creative expressions. This definition of the sharing economy distinguishes it from other related peer-to-peer and collaborative forms of production. Understanding the social and economic motivations for and implications of participating in the sharing economy is important to its regulation. Each of the papers in this special issue contributes to knowledge by linking the social and economic aspects of sharing economy practices to regulatory norms and mechanisms. We conclude this essay by suggesting future research to further clarify and render intelligible the sharing economy, not as a contradiction in terms but as an empirically observable realm of socio-economic activity.

Based on our teaching experience in medicine and psychology degree programs, we examine different aspects of human evolution that can help students to understand how the human body and mind work and why they are vulnerable to certain diseases. Three main issues are discussed: 1) the necessity to consider not only the mechanisms, i.e. the "proximate causations", implicated in biological processes but also why these mechanisms have evolved, i.e. the "ultimate causations" or "adaptive significance", to understand the functioning and malfunctioning of human body and mind; 2) examples of how human vulnerabilities to disease are caused by phylogenetic constraints, evolutionary tradeoffs reflecting the combined actions of natural and sexual selection, and/or mismatch between past and present environment (i.e., evolution of the eye, teeth and diets, erect posture and their consequences); 3) human pair-bonding and parent-offspring relationships as the result of socio-sexual selection and evolutionary compromises between cooperation and conflict. These psychobiological mechanisms are interwoven with our brain developmental plasticity and the effects of culture in shaping our behavior and mind, and allow a better understanding of functional (normal) and dysfunctional (pathological) behaviors. Thus, because the study of human evolution offers a powerful framework for clinical practice and research, the curriculum studiorum of medical and psychology students should include evolutionary biology and human phylogeny.
Full Text Available Barley grass powder is the best functional food that provides nutrition and eliminates toxins from cells in human beings; however, its functional ingredients have played an important role as health benefit. In order to better cognize the preventive and therapeutic role of barley grass for chronic diseases, we carried out the systematic strategies for functional ingredients of barley grass, based on the comprehensive databases, especially the PubMed, Baidu, ISI Web of Science, and CNKI, between 2008 and 2017. Barley grass is rich in functional ingredients, such as gamma-aminobutyric acid (GABA, flavonoids, saponarin, lutonarin, superoxide dismutase (SOD, K, Ca, Se, tryptophan, chlorophyll, vitamins (A, B1, C, and E, dietary fiber, polysaccharide, alkaloid, metallothioneins, and polyphenols. Barley grass promotes sleep; has antidiabetic effect; regulates blood pressure; enhances immunity; protects liver; has anti-acne/detoxifying and antidepressant effects; improves gastrointestinal function; has anticancer, anti-inflammatory, antioxidant, hypolipidemic, and antigout effects; reduces hyperuricemia; prevents hypoxia, cardiovascular diseases, fatigue, and constipation; alleviates atopic dermatitis; is a calcium supplement; improves cognition; and so on. These results support that barley grass may be one of the best functional foods for preventive chronic diseases and the best raw material of modern diet structure in promoting the development of large health industry and further reveal that GABA, flavonoids, SOD, K-Ca, vitamins, and tryptophan mechanism of barley grass have preventive and therapeutic role for chronic diseases. This paper can be used as a scientific evidence for developing functional foods and novel drugs for barley grass for preventive chronic diseases.

The personhood of the physician is a crucial element in accomplishing the goals of medicine. We review claims made on behalf of the humanities in guiding professional identity formation. We explore the dichotomy that has evolved, since the Renaissance, between the humanities and the natural sciences. The result of this evolution is an historic misconstrual, preoccupying educators and diverting them from the moral development of physicians. We propose a curricular framework based on the recovery of Aristotelian concepts that bridge identity and activity. The humanities and the natural sciences, jointly and severally, can fulfill developmental, characterological and instrumental purposes.

Pregnancy places exceptional demands on vitamin D and calcium availability; thus, their deficiencies during pregnancy threaten the woman and her fetus. Globally, vitamin D and other micronutrient deficiencies are common during pregnancy, especially in developing countries where pregnant women have less access to nutritional supplements. Vitamin D deficiency has been reported to be as high as 40% among pregnant women. As a pregnancy progresses, the requirements for vitamin D increase and thus, can worsen preexisting hypovitaminosis D. Consequently, hypovitaminosis D is increasingly associated with a higher incidence of fetal miscarriage, preeclampsia, gestational diabetes, bacterial vaginosis, and impaired fetal and childhood growth and development. This review explores the recent advances in the understanding of vitamin D and the pivotal role it plays in human reproduction, with an emphasis on pregnancy and its outcomes. Given the seriousness of the issue, there is a pressing need for clinicians to become aware of the risks associated with not identifying and correcting vitamin D deficiency. Identifying and correcting vitamin D deficiency, including safe exposure to sunlight, is particularly relevant for those who seek assistance with fertility issues or prenatal counseling, and those in the beginning of their pregnancy. The data point to a significant protective effects of vitamin D during pregnancy when the 25(OH)D serum level exceeds 30 ng/mL before pregnancy and during the first trimester and, sufficient levels are maintained throughout the pregnancy.

The capacity to look inside the living human brain and image its function has been present since the early 1980s. There are some clinicians who use functional brain imaging for diagnostic or prognostic purposes, but much of the work done still relates to research evaluation of brain function. There is a striking dichotomy in the use of functional brain imaging between these two fields. Clinical evaluation of a brain PET or SPECT scan is subjective; that is, a Nuclear Medicine physician examines the brain image, and states whether the brain image looks normal or abnormal. On the other hand, modern research evaluation of functional brain images is almost always objective. Brain images are processed and analyzed with advanced software tools, and a mathematical result that relates to regional changes in brain activity is provided. The potential for this research methodology to provide a more accurate and reliable answer to clinical questions about brain function and pathology are immense, but there are still obstacles to overcome. Foremost in this regard is the use of a standardized normal control database for comparison of patient scan data. The tools and methods used in objective analysis of functional imaging data, as well as potential clinical applications will be the focus of my presentation

The paper challenges the notion that any Fitts' Law model can be applied generally to human-computer interaction, and proposes instead that applying Fitts' Law requires knowledge of the users' sequence of movements, direction of movement, and typical movement amplitudes as well as target sizes. Two experiments examined a text selection task with sequences of controlled movements (point-click and point-drag). For the point-click sequence, a Fitts' Law model that used the diagonal across the text object in the direction of pointing (rather than the horizontal extent of the text object) as the target size provided the best fit for the pointing time data, whereas for the point-drag sequence, a Fitts' Law model that used the vertical size of the text object as the target size gave the best fit. Dragging times were fitted well by Fitts' Law models that used either the vertical or horizontal size of the terminal character in the text object. Additional results of note were that pointing in the point-click sequence was consistently faster than in the point-drag sequence, and that pointing in either sequence was consistently faster than dragging. The discussion centres around the need to define task characteristics before applying Fitts' Law to an interface design or analysis, analyses of pointing and of dragging, and implications for interface design.

The antibiotic resistance is natural in bacteria and predates the human use of antibiotics. Numerous antibiotic resistance genes (ARGs) have been discovered to confer resistance to a wide range of antibiotics. The ARGs in natural environments are highly integrated and tightly regulated in specific bacterial metabolic networks. However, the antibiotic selection pressure conferred by the use of antibiotics in both human medicine and agriculture practice leads to a significant increase of antibiotic resistance and a steady accumulation of ARGs in bacteria. In this review, we summarized, with an emphasis on an ecological point of view, the important research progress regarding the collective ARGs (antibiotic resistome) in bacterial communities of natural environments, human and animals, i.e., in the one health settings.We propose that the resistance gene flow in nature is "from the natural environments" and "to the natural environments"; human and animals, as intermediate recipients and disseminators, contribute greatly to such a resistance gene "circulation."

The dearth of health personnel in low income countries has attracted global attention. Ways as to how health care services can be delivered in a more efficient and effective way using available health personnel are being explored. Task-sharing expands the responsibilities of low-cadre health workers and allows them to share these responsibilities with highly qualified health care providers in an effort to best utilize available human resources. This is appropriate in a country like Nigeria where there is a shortage of qualified health professionals and a huge burden of maternal mortality resulting from obstetric complications like pre-eclampsia. This study examines the prospect for task-sharing among Community Health Extension Workers (CHEW) for the detection of early signs of pre-eclampsia, in Ogun State, Nigeria. This study is part of a larger community-based trial evaluating the acceptability of community treatment for severe pre-eclampsia in Ogun State, Nigeria. Data was collected between 2011 and 2012 using focus group discussions; seven with CHEWs (n = 71), three with male decision-makers (n = 35), six with community leaders (n = 68), and one with member of the Society of Obstetricians and Gynaecologists of Nigeria (n = 9). In addition, interviews were conducted with the heads of the local government administration (n = 4), directors of planning (n = 4), medical officers (n = 4), and Chief Nursing Officers (n = 4). Qualitative data were analysed using NVivo version 10.0 3 computer software. The non-availability of health personnel is a major challenge, and has resulted in a high proportion of facility-based care performed by CHEWs. As a result, CHEWs often take on roles that are designated for senior health workers. This role expansion has exposed CHEWs to the basics of obstetric care, and has resulted in informal task-sharing among the health workers. The knowledge and ability of CHEWs to perform basic clinical assessments

The increasing release of fission products from nuclear weapon tests in the environment has been rising the levels of radioactive contamination of food chains caused by the fall-out of these elements. In cases of accidental exposure, human subjects could be submitted to an internal contamination, which is likely to include several radionuclides. Special concern must be given, however, to the radioactive isotopes of strontium, cesium and iodine, along with the highly radio toxic transuranium elements like cerium. It was found that sodium alginate, a polyelectrolyte commonly used in food industry and obtained from brown algae (Phaeophyceae), provides the selective suppression of absorption of radioactive strontium presented in the ingested food material with no disturbance of the electrolyte balance nor undesirable side effects, even for a long term treatment. Moreover, these patterns were maintained when alginate was associated to other decontamination additives, specially those related to the other radioisotopes mentioned above, as, in this case, losses in the effectiveness, mutual interference or adverse health effects were not detected. These conclusions ground the discussion about the present trend in the usual choice of EDTA/DTPA complex therapy rather than of alginate therapy for medical assistance of radiocontaminated patients, although they corroborate the efficiency and usefulness of alginate salts in situations related to extensive intakes of strontium radioisotopes alone or associated to other fission products. The purpose of the present work is to make a general review of the alginate therapy as well as to discuss its present and future therapeutic importance from the scientific and institutional points of view.

Retroviruses, as part of their replication cycle, become integrated into the genome of their host. When this occurs in the germline the integrated proviruses can become an endogenous retrovirus (ERV) which may eventually become fixed in the population. ERVs are present in the genomes of all vertebrates including humans, where more than 50 groups of human endogenous retrovirus (HERVs) have been described within the last 30 years. Despite state-of-the-art genomic tools available for retroviral discovery and the large number of retroviral sequences described to date, there are still gaps in understanding retroviral macroevolutionary patterns and host-retrovirus interactions and a lack of a coherent systematic classification particularly for HERVs. Here, we discuss the current knowledge on ERV (and HERV) classification, distribution and origins focusing on the role of cross-species transmission in retroviral diversity. © 2016 APMIS.

Psychiatry and related mental health fields, in particular psychotherapy, have a long history of close ties with the humanities. That bond has weakened, however, over the last few decades as medicalized views of mental health and treatment have emerged. In this paper, we explore the potential of the reintroduction of the humanities, specifically novels and related literary genre, into the supervision of student clinicians working with clients who have psychosis. We believe that incorporation of novels and related literary genre into supervision can lead to unique and deepened understanding of the experience of psychosis, and can create an opportunity for a working therapeutic alliance. The potential mechanisms that create these unique opportunities to understand psychopathology are explored, and considerations for the implications for treatment, training, and future research are presented.

The Brazilian national curriculum guidelines for undergraduate medicine courses inspired and influenced the groundwork for knowledge acquisition, skills development and the perception of ethical values in the context of professional conduct. The evaluation of ethics education in research involving human beings in undergraduate medicine curriculum in Brazil, both in courses with active learning processes and in those with traditional lecture learning methodologies. Curricula and teaching projects of 175 Brazilian medical schools were analyzed using a retrospective historical and descriptive exploratory cohort study. Thirty one medical schools were excluded from the study because of incomplete information or a refusal to participate. Active research for information from institutional sites and documents was guided by terms based on 69 DeCS/MeSH descriptors. Curriculum information was correlated with educational models of learning such as active learning methodologies, tutorial discussions with integrated curriculum into core modules, and traditional lecture learning methodologies for large classes organized by disciplines and reviewed by occurrence frequency of ethical themes and average hourly load per semester. Ninety-five medical schools used traditional learning methodologies. The ten most frequent ethical themes were: 1--ethics in research (26); 2--ethical procedures and advanced technology (46); 3--ethic-professional conduct (413). Over 80% of schools using active learning methodologies had between 50 and 100 hours of scheduled curriculum time devoted to ethical themes whereas more than 60% of traditional learning methodology schools devoted less than 50 hours in curriculum time to ethical themes. The data indicates that medical schools that employ more active learning methodologies provide more attention and time to ethical themes than schools with traditional discipline-based methodologies. Given the importance of ethical issues in contemporary medical

The number of death cases of forensic interest grows up every year. When decomposed or skeletal remains come out from the soil, the bones become of anthropological competence and the scene of crime become of soil specialists competence. The present study concerns real cases of buried/hidden remains in clandestine graves which have been studied in order to prove the permanence in soil even if the soil particles have been washed away or the body is no more buried. One hypothesis has been taken in account, related to the evidences of vivianite crystallization on the bones. The vivianite is an iron hydrate phosphate (Fe3(PO4)2·8(H2O)) that usually forms in anoxic, reducing and rich in organic matter conditions. In these conditions the iron in the soil is in reduced form (Fe2+) and associates with the phosphorous, present in the environment, as attested in archaeological contexts. Going back to the cases of buried/hidden remains, it is possible to state that the soil can be source of iron, while the bones can supply phosphorous and the decomposition process induces the anoxic/reducing conditions in the burial area. In this light, the presence of vivianite crystallizations on the bones could be a method to discriminate burial (i.e. permanence in soil) even if the remains are found in a different context than a clandestine grave. Analyses have been performed using petrographic microscope and scanning electron microscope microanalysis (SEM-EDS) on bones, and point out the presence of vivianite crystallizations on the bones. This evidence, thanks to the significance of vivianite in the archaeological context, can be regarded as a marker of the permanence of the human remains into the soil, like a ‘buried evidence' testimonial; on the contrary the absence of vivianite is not indicative of a ‘non buried status'. Further studies and new experiments are in progress in order to clarify the pathways of vivianite crystallization on different skeletal districts, in different

The ability to communicate to others and express ourselves is a basic human need. As we develop our understanding of the world, based on our upbringing, education and so on, our perspective and the way we communicate can differ from those around us. Engaging and interacting with others is a critical part of healthy living. It is the responsibility of the individual to ensure that they are understood in the way they intended.Shared language refers to people developing understanding amongst themselves based on language (e.g. spoken, text) to help them communicate more effectively. The key to understanding language is to first notice and be mindful of your language. Developing a shared language is an ongoing process that requires intention and time, which results in better understanding.Shared language is critical to collaboration, and collaboration is critical to business and education. With whom and how many people do you connect? Your 'shared language' makes a difference in the world. So, how do we successfully do this? This paper shares several strategies.Your sphere of influence will carry forward what and how you are communicating. Developing and nurturing a shared language is an essential element to enhance communication and collaboration whether it is simply between partners or across the larger community of business and customers. Constant awareness and education is required to maintain the shared language. We are living in an increasingly smaller global community. Business is built on relationships. If you invest in developing shared language, your relationships and your business will thrive.

can sustain chemosynthetic seep ecosystems comparable to, and sometimes sharing species with, hot vents. What will Alvin's next 50 years discover? During 2011-12, Alvin has undergone a transformation, including a larger personnel sphere with more & larger viewports to provide improved overlapping fields of view for the pilot & observers. The new Alvin will be certified for operations to 4500m depth initially, but the new sphere will be 6500m-rated and planned future upgrades will ultimately allow the vehicle to dive that deep, enabling human access to 98% of the global ocean floor. This will allow the study of processes and dynamics of Earth's largest ecosystem (the abyssal plains) as well as margin and ridge environments and the overlying water column. Meantime, the current upgrades to Alvin already include a suite of scientific enhancements including new HD video & still imaging, sophisticated data acquisition systems for seafloor observations and mapping, a new work platform with greater payload capacity and improved observer ergonomics. The new Alvin is poised to play important roles in core Earth and Life science programs and to serve large-scale programs such as the Ocean Observatory Initiative (OOI) and the International Ocean Discovery Program (IODP). It will continue to attract, engage and inspire a new generation of scientists & students to explore and study the largest ecosystem on Earth, just as it has done throughout its first half century.

Our previous study revealed that Vav3 oncogene is overexpressed in human prostate cancer, activates androgen receptor, and stimulates growth in prostate cancer cells. The current study is to determine a potential role of Vav3 oncogene in human breast cancer and impact on estrogen receptor a (ERα)-mediated signaling axis. Immunohistochemistry analysis was performed in 43 breast cancer specimens and western blot analysis was used for human breast cancer cell lines to determine the expression level of Vav3 protein. The impact of Vav3 on breast cancer cell growth was determined by siRNA knockdown of Vav3 expression. The role of Vav3 in ERα activation was examined in luciferase reporter assays. Deletion mutation analysis of Vav3 protein was performed to localize the functional domain involved in ERα activation. Finally, the interaction of Vav3 and ERα was assessed by GST pull-down analysis. We found that Vav3 was overexpressed in 81% of human breast cancer specimens, particularly in poorly differentiated lesions. Vav3 activated ERα partially via PI3K-Akt signaling and stimulated growth of breast cancer cells. Vav3 also potentiated EGF activity for cell growth and ERα activation in breast cancer cells. More interestingly, we found that Vav3 complexed with ERα. Consistent with its function for AR, the DH domain of Vav3 was essential for ERα activation. Vav3 oncogene is overexpressed in human breast cancer. Vav3 complexes with ERα and enhances ERα activity. These findings suggest that Vav3 overexpression may aberrantly enhance ERα-mediated signaling axis and play a role in breast cancer development and/or progression

Why do members of the public share some scientific findings and not others? What can scientists do to increase the chances that their findings will be shared widely among nonscientists? To address these questions, we integrate past research on the psychological drivers of interpersonal communication with a study examining the sharing of hundreds of recent scientific discoveries. Our findings offer insights into (i) how attributes of a discovery and the way it is described impact sharing, (ii) who generates discoveries that are likely to be shared, and (iii) which types of people are most likely to share scientific discoveries. The results described here, combined with a review of recent research on interpersonal communication, suggest how scientists can frame their work to increase its dissemination. They also provide insights about which audiences may be the best targets for the diffusion of scientific content.
Full Text Available Defects involving specialised areas with characteristic anatomical features, such as the nipple, upper eyelid, and lip, benefit greatly from the use of sharing procedures. The vulva, a complex 3-dimensional structure, can also be reconstructed through a sharing procedure drawing upon the contralateral vulva. In this report, we present the interesting case of a patient with chronic, massive, localised lymphedema of her left labia majora that was resected in 2011. Five years later, she presented with squamous cell carcinoma over the left vulva region, which is rarely associated with chronic lymphedema. To the best of our knowledge, our management of the radical vulvectomy defect with a labia majora sharing procedure is novel and has not been previously described. The labia major flap presented in this report is a shared flap; that is, a transposition flap based on the dorsal clitoral artery, which has consistent vascular anatomy, making this flap durable and reliable. This procedure epitomises the principle of replacing like with like, does not interfere with leg movement or patient positioning, has minimal donor site morbidity, and preserves other locoregional flap options for future reconstruction. One limitation is the need for a lax contralateral vulva. This labia majora sharing procedure is a viable option in carefully selected patients.

The ability to communicate with others is one of the most important human social functions, yet communication is not always investigated from a social perspective. This research examined the role that shared social identity plays in communication effectiveness using a minimal group paradigm. In two experiments, participants constructed a model using instructions that were said to be created by an ingroup or an outgroup member. Participants made models of objectively better quality when working from communications ostensibly created by an ingroup member (Experiments 1 and 2). However, this effect was attenuated when participants were made aware of a shared superordinate identity that included both the ingroup and the outgroup (Experiment 2). These findings point to the importance of shared social identity for effective communication and provide novel insights into the social psychology of communication. © 2014 by the Society for Personality and Social Psychology, Inc.

Data sharing is essential for a better understanding of genetic disorders. Good phenotype coding plays a key role in this process. Unfortunately, the two most widely used coding systems in medicine, ICD-10 and SNOMED-CT, lack information necessary for the detailed classification and annotation of rare and genetic disorders. This prevents the optimal registration of such patients in databases and thus data-sharing efforts. To improve care and to facilitate research for patients with metabolic disorders, we developed a new coding system for metabolic diseases with a dedicated group of clinical specialists. Next, we compared the resulting codes with those in ICD and SNOMED-CT. No matches were found in 76% of cases in ICD-10 and in 54% in SNOMED-CT. We conclude that there are sizable gaps in the SNOMED-CT and ICD coding systems for metabolic disorders. There may be similar gaps for other classes of rare and genetic disorders. We have demonstrated that expert groups can help in addressing such coding issues. Our coding system has been made available to the ICD and SNOMED-CT organizations as well as to the Orphanet and HPO organizations for further public application and updates will be published online (www.ddrmd.nl and www.cineas.org). © 2013 WILEY PERIODICALS, INC.

Current ground robots are largely employed via tele-operation and provide their operators with useful tools to extend reach, improve sensing, and avoid dangers. To move from robots that are useful as tools to truly synergistic human-robot teaming, however, will require not only greater technical capabilities among robots, but also a better understanding of the ways in which the principles of teamwork can be applied from exclusively human teams to mixed teams of humans and robots. In this respect, a core characteristic that enables successful human teams to coordinate shared tasks is their ability to create, maintain, and act on a shared understanding of the world and the roles of the team and its members in it. The team performance literature clearly points towards two important cornerstones for shared understanding of team members: mental models and situation awareness. These constructs have been investigated as products of teams as well; amongst teams, they are shared mental models and shared situation awareness. Consequently, we are studying how these two constructs can be measured and instantiated in human-robot teams. In this paper, we report results from three related efforts that are investigating process and performance outcomes for human robot teams. Our investigations include: (a) how human mental models of tasks and teams change whether a teammate is human, a service animal, or an advanced automated system; (b) how computer modeling can lead to mental models being instantiated and used in robots; (c) how we can simulate the interactions between human and future robotic teammates on the basis of changes in shared mental models and situation assessment.

Full Text Available Collecting evidences about organized crime act of sexual exploitation in human begins often is very difficult because of high level of organization, secrecy ant precaution taken during committing prostitution, pornography, sex tourism and human trafficking. On the other side, high illegal profit enable criminals to engage "expensive" and experienced lawyers, whose often make values and reliability of collected evidences questionable, appealing to irregularities during police collecting procedure. Among traditional criminalities methods and proofing activities, in the study, modern tendencies in special investigative measures and techniques are considered. After that, there is pointing at specificity, meaning and value of material tracks and objects, which are essential for proofing crime act or perpetrator’s guiltiness. On the end, there is pointing at importance of victims’ cooperation in collecting evidences about their sexual exploitation.

The authors discuss the relation between perverse psychic formations and the ability to develop a mind of one's own. The authors characterize the formation of perversity in terms of failure to develop the key capacities of thinking, mourning, and loving. These failures result in the abolishment of thinking and the repudiation of separateness and lead to the creation of different kinds of twisted coalitions, which shape the transference-counter-transference matrix. Persons with perverse psychic organizations have difficulties developing their own minds due to their refusal to acknowledge human limitations and their inability to accept the fundamental differences of human existence: self-other, child-adult, male-female. These characterizations are illustrated by clinical material, including a detailed analytic session, demonstrating the perverse aggresivization and sexualization of the analytic relationship. The role of the analyst is to detoxify the violence and destruction and to translate the language of perversion into the language of love.

According to the free radical theory of aging, reactive oxygen species (ROS) act as a driving force of the aging process, and it is generally believed that mitochondrial dysfunction is a major source of increased oxidative stress in tissues with high content of mitochondria, such as muscle or brain....... However, recent experiments in mouse models of premature aging have questioned the role of mitochondrial ROS production in premature aging. To address the role of mitochondrial impairment and ROS production for aging in human muscles, we have analyzed mitochondrial properties in muscle fibres isolated...... from the vastus lateralis of young and elderly donors. Mitochondrial respiratory functions were addressed by high-resolution respirometry, and ROS production was analyzed by in situ staining with the redox-sensitive dye dihydroethidium. We found that aged human skeletal muscles contain fully functional...

1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) was found in 1983 to cause a syndrome virtually identical to Parkinson's Disease in humans and other primates. The symptoms, as in idiopathic Parkinson's syndrome, are due to destruction of dopaminergic neurons in the pars compacta of the substantia nigra resulting in depletion of dopamine in the basal ganglia. The mechanism of toxicity was investigated with a dopamine containing cell line, PC12, a MPTP resistant variant (MPTP r ), and synaptosomes from the striate cortex of mice, rats, guinea pigs and a monkey. The mechanism of acute effects was studied with membrane preparations from human and rat striate cortex. MPTP displaced [ 3 H]haloperidol from binding sites in human and rat striate cortex, but could not displace [ 3 H]flupenthixol, suggesting that MPTP is a D2 receptor ligand of equivalent potency in both species. MPTP was a competitive inhibitor of uptake of [ 3 H]dopamine in PC12 but did not accumulate in PC12 or in synaptosomes of rat, guinea pig, mouse or monkey striate cortex. 100 uM MPTP depleted catecholamine levels in PC12 cells by about 50%, without killing

Can enzymatically dispersed testicular cells from adult men reassemble into seminiferous cord-like structures in vitro? Adult human testicular somatic cells reassembled into testicular cord-like structures via dynamic interactions of Sertoli and peritubular cells. In vitro approaches using dispersed single cell suspensions of human testes to generate seminiferous tubule structures and to initiate their functionality have as yet shown only limited success. Testes from 15 adult gender dysphoria patients (mean ± standard deviation age 35 ± 9.3 years) showing spermatogonial arrest became available for this study after sex-reassignment surgery. In vitro primary testicular somatic cell cultures were generated to explore the self-organizing ability of testicular somatic cells to form testis cords over a 2-week period. Morphological phenotype, protein marker expression and temporal dynamics of cell reassembly were analyzed. Cell suspensions obtained by two-step enzymatic digestion were plated onto glass coverslips in 24-well plates. To obtain adherent somatic cells, the supernatant was discarded on Day 2. The culture of the attached cell population was continued. Reassembly into cord-like structures was analyzed daily by microscopic observations. Endpoints were qualitative changes in morphology. Cell types were characterized by phase-contrast microscopy and immunohistochemistry. Dynamics of cord formation were recorded by time-lapse microscopy. Primary adult human testicular cells underwent sequential morphological changes including compaction and reaggregation resulting in round or elongated cord-like structures. Time-lapse video recordings within the first 4 days of culture revealed highly dynamic processes of migration and coalescence of reaggregated cells. The cellular movements were mediated by peritubular cells. Immunohistochemical analysis showed that both SRY-related high mobility box 9-positive Sertoli and α-smooth muscle actin-positive peritubular myoid cells

The most publicly justifiable application of human cloning, if there is one at all, is to provide self-compatible cells or tissues for medical use, especially transplantation. Some have argued that this raises no new ethical issues above those raised by any form of embryo experimentation. I argue that this research is less morally problematic than other embryo research. Indeed, it is not merely morally permissible but morally required that we employ cloning to produce embryos or fetuses for the sake of providing cells, tissues or even organs for therapy, followed by abortion of the embryo or fetus.

The Fourteenth Amendment was intended to protect people from discrimination and harm from other people. Racism is not the only thing people need protection from. As a constitutional principle, the Fourteenth Amendment is not confined to its historical origin and purpose, but is available now to protect all human beings, including all unborn human beings. The Supreme Court can define "person" to include all human beings, born and unborn. It simply chooses not to do so. Science, history and tradition establish that unborn humans are, from the time of conception, both persons and human beings, thus strongly supporting an interpretation that the unborn meet the definition of "person" under the Fourteenth Amendment. The legal test used to extend constitutional personhood to corporations, which are artificial "persons" under the law, is more than met by the unborn, demonstrating that the unborn deserve the status of constitutional personhood. There can be no "rule of law" if the Constitution continues to be interpreted to perpetuate a discriminatory legal system of separate and unequal for unborn human beings. Relying on the reasoning of the Supreme Court in Brown v. Board of Education, the Supreme Court may overrule Roe v. Wade solely on the grounds of equal protection. Such a result would not return the matter of abortion to the states. The Fourteenth Amendment, properly interpreted, would thereafter prohibit abortion in every state.

Stimulation of different spinal cord segments in humans is a widely developed clinical practice for modification of pain, altered sensation, and movement. The human lumbar cord has become a target for modification of motor control by epidural and, more recently, by transcutaneous spinal cord stimulation. Posterior columns of the lumbar spinal cord represent a vertical system of axons and when activated can add other inputs to the motor control of the spinal cord than stimulated posterior roots. We used a detailed three-dimensional volume conductor model of the torso and the McIntyre-Richard-Grill axon model to calculate the thresholds of axons within the posterior columns in response to transcutaneous lumbar spinal cord stimulation. Superficially located large-diameter posterior column fibers with multiple collaterals have a threshold of 45.4 V, three times higher than posterior root fibers (14.1 V). With the stimulation strength needed to activate posterior column axons, posterior root fibers of large and small diameters as well as anterior root fibers are coactivated. The reported results inform on these threshold differences, when stimulation is applied to the posterior structures of the lumbar cord at intensities above the threshold of large-diameter posterior root fibers. © 2011, Copyright the Authors.

Exposure of heavy metals to humans is higher today than ever before in modern history due to continuously increasing industrialization around the globe. Industrial wastes are rich in heavy metals and these wastes are discharged near agricultural fields or mixed with soil, from where these metals are taken up by the crops and are finally transported to humans. Due to this increasing threat of heavy metals contamination in food, it is necessary to analyze the food before consumption. Content of selected metals (Cd, Cr, Cu, Pb and Zn) in cow milk is determined in this study. To investigate the possible pathways of these metals to reach in milk; fodder supplied to these cows was analyzed besides analysis of soil samples on which this fodder was grown. Pearson correlation among metal contents in soil-forage and forage-milk was also determined to check the route of transfer of these metals from soil to forage and from forage to milk. It was found that a strong correlation (p < 0.5) exists for Cr, Cd, Cu and Zn. This shows that these metals are mainly transferred through soil. However, a weak correlation was found for Pb, which shows that Pb is introduced into forage through some other source (automobile exhaust etc.). A comparison of present study is also done with previously reported work from other countries on metal contents in milk and findings of both the studies were in good agreement mutually. (author)

Change in behaviour is usually the first response to human-induced environmental change and key for determining whether a species adapts to environmental change or becomes maladapted. Thus, understanding the behavioural response to human-induced changes is crucial in the interplay between ecology, evolution, conservation and management. Yet the behavioural response to fishing activities has been largely ignored. We review studies contrasting how fish behaviour affects catch by passive (e.g., long lines, angling) versus active gears (e.g., trawls, seines). We show that fishing not only targets certain behaviours, but it leads to a multitrait response including behavioural, physiological and life-history traits with population, community and ecosystem consequences. Fisheries-driven change (plastic or evolutionary) of fish behaviour and its correlated traits could impact fish populations well beyond their survival per se , affecting predation risk, foraging behaviour, dispersal, parental care, etc., and hence numerous ecological issues including population dynamics and trophic cascades . In particular, we discuss implications of behavioural responses to fishing for fisheries management and population resilience. More research on these topics, however, is needed to draw general conclusions, and we suggest fruitful directions for future studies.

The indoor detection of the human body's thermal trace plays an important role in the fields of infrared detecting, scouting, infrared camouflage, and infrared rescuing and tracking. Currently, quantitative description and analysis for this technology are lacking due to the absence of human infrared radiation analysis. To solve this problem, we study the heating and cooling process by observing body contact and removal on an object, respectively. Through finite-element simulation and carefully designed experiments, an analytical model of the infrared trace of body contact is developed based on infrared physics and heat transfer theory. Using this model, the impact of body temperature on material thermal parameters is investigated. The sensitivity of material thermal parameters, the thermal distribution, and the changes of the thermograph's contrast are then found and analyzed. Excellent matching results achieved between the simulation and the experiments demonstrate the strong impact of temperature on material thermal parameters. Conclusively, the new model, simulation, and experimental results are beneficial to the future development and implementation of infrared trace technology.

Full Text Available In this perspective article, we consider the relationship between experience sharing and turn-taking. There is much evidence suggesting that human social interaction is permeated by two temporal organizations: (1 the sequential framework of turn-taking and (2 the concurrent framework of emotional reciprocity. From this perspective, we introduce two alternative hypotheses about how the relationship between experience sharing and turn-taking could be viewed. According to the first hypothesis, the home environment of experience sharing is in the concurrent framework of emotional reciprocity, while the motivation to share experiences is in tension with the sequential framework of turn-taking. According to the second hypothesis, then again, people’s inclination to coordinate their actions in terms of turn-taking is motivated precisely by their propensity to share experiences. We consider theoretical and empirical ideas in favor of both of these hypotheses and discuss their implications for future research.
I focus on the crucial links between the discovery of nonhuman primates by Westerners, discussions on our place in nature, the chain of being, racism, and the history of primate comparative anatomy and of so-called "anatomical human racial studies." Strikingly, for more than a millennium humans knew more about the internal anatomy of a single monkey species than about that of their own bodies. This is because Galen used monkeys to infer human anatomy, in line with the human-animal continuity implied by the Greek notion of scala naturae. With the rise of Christianity, nonhuman primates were increasingly seen in a negative way. A more positive view emerged in the 14th century when nonhuman primates were directly studied/seen by Europeans, culminating in Tyson's 1699 work showing that chimps share more gross anatomical similarities with humans than with monkeys. However, the discomfort caused by this human-chimp similarity then led to a new idea of animal-human discontinuity, now related not to anatomy but to "civilization": between Europeans vs. non-Europeans + other primates. Moreover, Linnaeus' Systema Naturae and the emergence of "anatomical racial studies" influenced by Camper's craniology then led to even more extreme ideas, such as the notion that Europeans were both mentally and morphologically "ideal." Unfortunately the biased and often incorrect "results" of such studies, combined with ideas based on Darwin's "struggle for survival", became crucial in propaganda that lead to the rise of eugenics in the end of the 19th/first half of 20th centuries and that culminated in Nazism. Since the 1950s there has been an emphasis on the continuity/unity between all human groups and other primates, in great part influenced by what happened during World War 2. Reviews such as this one are, therefore, particularly necessary to illuminate and guard against attitudes against "the Other" and racist ideologies that are re-emerging in modern political discourse across the

Full Text Available High densities of wild African savannah elephants (Loxodonta africana combined with widespread human land-use have increased human-elephant conflict in northern Botswana. Visible impacts (e.g. crop/property damage, injury/fatality of elephants on human well-being are well documented in scholarly literature while hidden impacts (e.g. emotional stress, restricted mobility are less so. This research uses qualitative methods to explore human experiences with elephants and perceived impacts of elephants on human well-being. Findings reveal participants are concerned about food insecurity and associated visible impacts of elephant crop raids. Findings also reveal participants are concerned about reduced safety and restricted mobility as hidden impacts threatening livelihoods and everyday life. Both visible and hidden impacts of elephants contribute to people's negative feelings towards elephants, as does the broader political context. This research emphasises the importance of investigating both visible and hidden impacts of elephants on human well-being to foster holistic understanding of human-elephant conflict scenarios and to inform future mitigation strategies.

Very often behind the human beings trafficking is the organised crime because is one of the most profitable criminal activities in the world. The numbers are very scary because it is estimated that the trafficked people to or within the EU are reaching several hundred thousands a year. The present study is intending to discover how the European Union intends to fight against the human beings trafficking, since there is a need to have a coherent action at the European level because of the criminals can easily operate across border.
The big news this week is, of course, the conclusions from the LHC performance workshop held in Chamonix from 6 to 10 February . The main recommendation, endorsed by CERN’s Machine Advisory Committee and adopted by the Management, is that the LHC will run at 4 TeV per beam this year. You can find all the details from Chamonix in the slides presented on Wednesday at the summary session, which leaves me free to talk about another important development coming up soon. In ten days time, a new kind of gathering will be taking place in Geneva, bringing together two previously separate conferences, one driven by physics, the other by the medical community, but both looking to apply physics to the advancement of health. The merger of the International Conference for Translational Research in Radio-Oncology and CERN’s workshop on Physics for Health in Europe (ICTR-PHE) makes for a very eclectic mix. Presentations range from active shielding for interplanetary flight to the rather...
Our limited knowledge and understanding of the behavior of the naturally occurring radionuclides in the environment, food and man have relied heavily on the skills of radiochemists. The purpose of this document is to lend an appreciation of the role of the radiochemist in programs designed to establish the concentration of uranium, thorium, radium and 210 Pb in a variety of sample matrices. Part I discusses the purposes and strategies for collection of environmental and human tissue samples, chemical and measurement methods, quality assurance and reporting of results. Part II summarizes our present knowledge on the concentrations of Uranium and Thorium Series radionuclides in the environment, diet and man. (author). 183 refs., 11 tabs., 6 figs

Here, we report the existence of meningeal lymphatic vessels in human and nonhuman primates (common marmoset monkeys) and the feasibility of noninvasively imaging and mapping them in vivo with high-resolution, clinical MRI. On T2-FLAIR and T1-weighted black-blood imaging, lymphatic vessels enhance with gadobutrol, a gadolinium-based contrast agent with high propensity to extravasate across a permeable capillary endothelial barrier, but not with gadofosveset, a blood-pool contrast agent. The topography of these vessels, running alongside dural venous sinuses, recapitulates the meningeal lymphatic system of rodents. In primates, meningeal lymphatics display a typical panel of lymphatic endothelial markers by immunohistochemistry. This discovery holds promise for better understanding the normal physiology of lymphatic drainage from the central nervous system and potential aberrations in neurological diseases.

Sporotrichosis is a subacute to chronic infection caused by members of the Sporothrix schenckii complex. Itraconazole is the first choice antifungal drug for treating this infection, with terbinafine and potassium iodide as alternatives and amphotericin B used in cases of severe infections. Correlation of antifungal susceptibility data with the clinical outcome of the patients is scarce. The aim of this study was to correlate clinical and mycological data in patients with refractory sporotrichosis. In this work, antifungal susceptibilities, determined according to the reference M38-A2 CLSI protocol, of 25 Sporothrix strains, isolated from seven human cases of sporotrichosis with adversities in the treatment, are presented. Tested drugs included itraconazole, ketoconazole, posaconazole, voriconazole, terbinafine, and amphotericin B. Fungi were identified using the T3B PCR fingerprinting. This method identified all strains as Sporothrix brasiliensis and also demonstrated a high degree of similarity between the strains. In general, voriconazole was ineffective against all strains, and elevated minimal inhibitory concentrations (MICs) were observed for amphotericin B. High itraconazole and terbinafine MICs were not observed in S. brasiliensis isolates from patients of this study. Moreover, a significant increase in itraconazole and terbinafine MIC values from strains isolated from the same patient in different periods was not observed. The results suggest that the antifungal susceptibility to terbinafine and itraconazole determined by the reference method does not play an important role in therapeutic failure of sporotrichosis and that acquisition of resistance during prolonged antifungal treatment is not likely to occur in S. brasiliensis. © The Author 2016.

Full Text Available Human prosociality is one of the defining characteristics of our species, yet the ontogeny of altruistic behavior remains poorly understood. The evolution of widespread food sharing in humans helped shape cooperation, family formation, life history, language, and the development of economies of scale. While the behavioral and ecological correlates of food sharing among adults are widely studied, very little is known about food sharing among children. Here, in the first study to analyze the food sharing patterns of hunter-gatherer children, we show that while sharing may be biased towards kin, reciprocity characterizes the majority of all sharing dyads, both related and unrelated. These data lend support to the recent claim that discrimination among kin might be linked with reciprocal altruism theory. Furthermore, we show that age positively correlates with an increase in sharing, both in frequency and amount, supporting recent suggestions that prosocial behaviors and egalitarianism develop strongly in middle childhood when children acquire the normative rules of their society.

Various custom-made phantoms designed to optimize magnetic resonance imaging (MRI) sequences have been created and subsequently reported in Japanese Society of Radiological Technology (JSRT). However, custom-made phantoms that correctly match the T 1 -value and T 2 -values of human brain tissue (gray matter and white matter) cannot be made easily or quickly. The aim of this project was to search for alternative materials, such as fruits and vegetables, for optimizing MRI sequences. The following eight fruits and vegetables were investigated: apple, tomato, melon, apple mango (Mangifera indica), banana, avocado, peach, and eggplant. Their potential was studied for use in modeling phantoms of normal human brain tissues. MRI (T 1 - and T 2 -weighted sequences) was performed on the human brain and the fruits and vegetables using various concentrations of contrast medium (gadolinium) in the same size tubes as the custom-made phantom. The authors compared the signal intensity (SI) in human brain tissue (gray matter and white matter) with that of the fruits and the custom-made phantom. The T 1 and T 2 values were measured for banana tissue and compared with those for human brain tissue in the literature. Our results indicated that banana tissue is similar to human brain tissue (both gray matter and white matter). Banana tissue can thus be employed as an alternative phantom for the human brain for the purpose of MRI. (author)

Full Text Available Mycobacterium avium subspecies paratuberculosis (MAP has emerged as a major health problem for domestic livestock and human beings. Reduced per animal productivity of domestic livestock seriously impacts the economics of dairy farming globally. High to very high bioload of MAP in domestic livestock and also in the human population has been reported from north India. Presence of live MAP bacilli in commercial supplies of raw and pasteurized milk and milk products indicates its public health significance. MAP is not inactivated during pasteurization, therefore, entering into human food chain daily. Recovery of MAP from patients with inflammatory bowel disease or Crohn's disease and animal healthcare workers suffering with chronic gastrointestinal problems indicate a close association of MAP with a number of chronic and other diseases affecting human health. Higher bioload of MAP in the animals increases the risk of exposure to the human population with MAP. This review summarizes the current status of MAP infection in animals as well as in human beings and also highlights the prospects of effective management and control of disease in animals to reduce the risk of exposure to human population.
Full Text Available This paper will focus on the issue of whether it is plausible to think about a human right to be assisted in dying. The right to be assisted in dying cannot be considered just a right of non-interference. It is better understood as a claim right because it demands assistance and positive actions. I will argue that the principles of individual autonomy and Kant’s notion of dignity taken independently cannot be considered plausible justification for the human right to be assisted in dying. Griffin’s personhood account points out that principles of liberty, minimum provision and autonomy must be taken together to justify human rights. Based on his theory, I will argue that a person with a terminal disease who was aware of her imminent death or who suffered from an intractable, incurable, irreversible disease may waive the right to life and choose death. Therefore, the right to life would not restrict the human right to be assisted in dying and a state that allowed the practice of assisted dying would not be disrespecting the human right to life. This article will defend that the personhood account is able to protect vulnerable people from making decisions under pressure and avoid the slippery slope objection.
Pathogenic strains of Yersinia enterocolitica isolated from domestic dogs (Canis familiaris) belonging to farmers are of the same subtype as pathogenic Y. enterocolitica strains isolated from humans and may be a source of human infection in Jiangsu Province, China.

We isolated 326 Yersinia enterocolitica strains from 5,919 specimens from patients with diarrhea at outpatient clinics, livestock, poultry, wild animals, insect vectors, food, and the environment in the cities of Nantong and Xuzhou in Jiangsu Province, China, from 2004 to 2008. The results showed that the 12 pathogenic strains were of the O:3 serotype. Six strains were isolated from domestic dogs (Canis familiaris) belonging to farmers and were found to be the primary carriers of pathogenic Y. enterocolitica strains, especially in Xuzhou. Pulsed-field gel electrophoresis analysis of the pathogenic strains from dogs belonging to farmers showed that they shared the same patterns as strains from diarrhea patients isolated in 1994. This indicates that the strains from domestic dogs have a close correlation with the strains causing human infections.

A sustainable human future requires both healthy ecosystems and communities in which people thrive, with opportunities for health, well-being, happiness, economic prosperity, and equity. To make progress towards this goal, two largely disparate communities of scholars and practitioners must come together: sustainability science needs to be integrated with the sciences of human health and well-being. The opportunity for such integration is particularly ripe for urbanizing regions which not only dominate energy and resource use but also increasingly represent the human habitat. We present a conceptual framework that integrates sustainability science with the sciences of human health and well-being to explicitly articulate testable hypotheses on the relationships between humans and their habitat. We are interested in human behaviors and metrics of health and well-being in relationship to the characteristics of the built environment at various scales from buildings to metro regions. Focusing on the U.S. Pacific Northwest (PNW) as a testbed, we are building on our current empirical studies on urban sprawl and ecosystem function including biodiversity, air quality, hydrological, biogeochemical, and human health to develop formal hypotheses on how alternative urban design and development patterns may influence health outcomes and well-being. The PNW is an ideal setting for this work because of the connected metropolitan areas within a region characterized by a spectacular diversity of aquatic and terrestrial ecosystems and deeply held cultural and political aspirations towards sustainability. The framework also highlights opportunities for translation of knowledge to practice in the design and planning of built environments. For example, understanding these associations is critical to assessing tradeoffs in design and planning strategies and exploring potential synergies that optimize both sustainability and human well-being. In complex systems such as cities, managers

Human Wharton's jelly-derived mesenchymal stromal cells (hWJMSCs) are possibly the most suitable allogeneic cell source for stromal cell therapy and tissue engineering applications because of their hypo-immunogenic and non-tumorigenic properties, easy availability and minimal ethical concerns. Furthermore, hWJMSCs possess unique properties of both adult mesenchymal stromal cells and embryonic stromal cells. The human umbilical cord (UC) is approximately 50-60 cm long and the existing studies in the literature have not provided information on which segment of the UC was studied. In this study, hWJMSCs derived from three anatomical segments of the UC are compared. Three segments of the whole UC, each 3 cm in length, were identified anatomically as the maternal, middle and fetal segments. The hWJMSCs from the different segments were analyzed via trypan blue exclusion assay to determine the growth kinetics and cell viability, flow cytometry for immunophenotyping and immunofluorescence and reverse transcriptase polymerase chain reaction (RT-PCR) for expression of stromal cell transcriptional factors. Furthermore, the trilineage differentiation potential (osteogenic, adipogenic and chondrogenic) of these cells was also assessed. hWJMSCs isolated from the maternal and fetal segments displayed greater viability and possessed a significantly higher proliferation rate compared with cells from the middle segment. Immunophenotyping revealed that hWJMSCs derived from all three segments expressed the MSC markers CD105, CD73, CD90, CD44, CD13 and CD29, as well as HLA-ABC and HLA-DR, but were negative for hematopoietic markers CD14, CD34 and CD45. Analysis of the embryonic markers showed that all three segments expressed Nanog and Oct 3/4, but only the maternal and fetal segments expressed SSEA 4 and TRA-160. Cells from all three segments were able to differentiate into chondrogenic, osteogenic and adipogenic lineages with the middle segments showing much lower differentiation

The myc family of oncogenes contains coding sequences that have been preserved in different species for over 400 million years. This conservation (which implies functional selection) is broadly represented throughout the C-terminal portion of the human c-myc protein but is largely restricted to three cluster of amino acid sequences in the N-terminal region. The authors have examined the role that the latter three regions of the c-myc protein might play in the transforming function of the c-myc gene. Several mutations, deletions and frameshifts, were introduced into the c-myc gene, and these mutant genes were tested for their ability to collaborate with the EJ-ras oncogene to transform rat embryo fibroblasts. Complete elimination of the first two N-terminal conserved segments abolished transforming activity. In contrast, genes altered in a portion of the second or the entire third conserved segment retained their transforming activity. Thus, the latter two segments are not required for the transformation process, suggesting that they serve another function related only to the normal expression of the c-myc gene

The gut microbiome is critical for human health, and its alteration is associated with intestinal, autoimmune and metabolic diseases. Numerous studies have focused on prevention or treatment of dysbiotic microbiome to reduce the risk or effect of these diseases. A key issue is to define the microbiome associated with the state of good health. The purpose of this review is to describe factors influencing the gut microbiome with special emphasis on contributions from Latin America. In addition, we will highlight opportunities for future studies on gut microbiome in Latin America. A relevant factor influencing gut microbiome composition is geographical location associated with specific genetic, dietary and lifestyle factors. Geographical specificities suggest that a universal 'healthy microbiome' is unlikely. Several research programs, mostly from Europe and North America, are extensively sequencing gut microbiome of healthy people, whereas data from Latin America remain scarce yet slowly increasing. Few studies have shown difference in the composition of gut microbiome between their local populations with that of other industrialized countries (North American populations). Latin America is composed of countries with a myriad of lifestyles, traditions, genetic backgrounds and socioeconomic conditions, which may determine differences in gut microbiome of individuals from different countries. This represents an opportunity to better understand the relationship between these factors and gut microbiome.

Urinary excretion of free mefenamic acid was investigated in 16 healthy human volunteers, eight males and eight females, following the oral administration of 500 mg tablet of mefenamic acid. Urine samples were collected at pre-determined schedule and drug concentration was determined by spectrophotometric method. The total recovery of free mefenamic acid was 1.526 +- 0.128 and 1.193 +- 0.112% in male and female volunteers respectively. The average +- S.E values for diuresis, pH and rate of excretion of mefenamic acid was 0.0160 +- 0.004 mL/min./kg of body weight, 6.22 +- 0.167, 0.077 +- 0.016 micro g min/sup -1/kg/sup -1/in male while 0.0084 +- 0.0023mL min/sup -1/kg-1 of body weight, 6.35 +- 0.164, 0.054 +- 0.008 micro g min/sup -1/kg/sup -1/respectively in female volunteers. The results obtained are different from the earlier studies due to variability in dose, gender variation, fluctuation in urine pH, environmental conditions and nutritional ingredients. (author)

All over the world, humans (Homo sapiens) display resource-sharing behavior, and common patterns of sharing seem to exist across cultures. Humans are not the only primates to share, and observations from the wild have long documented food sharing behavior in our closest phylogenetic relatives, chimpanzees (Pan troglodytes) and bonobos (Pan paniscus). However, few controlled studies have been made in which groups of Pan are introduced to food items that may be shared or monopolized by a first food possessor, and very few studies have examined what happens to these sharing patterns if the food in question is a highly attractive, monopolizable food source. The one study to date to include food quality as the independent variable used different types of food as high- and low-value items, making differences in food divisibility and size potentially confounding factors. It was the aim of the present study to examine the sharing behavior of groups of captive chimpanzees and bonobos when introducing the same type of food (branches) manipulated to be of 2 different degrees of desirability (with or without syrup). Results showed that the large majority of food transfers in both species came about as sharing in which group members were allowed to cofeed or remove food from the stock of the food possessor, and the introduction of high-value food resulted in more sharing, not less. Food sharing behavior differed between species in that chimpanzees displayed significantly more begging behavior than bonobos. Bonobos, instead, engaged in sexual invitations, which the chimpanzees never did. (PsycINFO Database Record (c) 2015 APA, all rights reserved).

The welfare of research participants must be guaranteed by international ethical standards. This article communicates the procedures of the Research Ethics Committee of the School of Medicine, University of Chile (CEISH). The new Chilean legislation on research in human beings is also discussed. Law 20.120: "On scientific research in human beings, its genome and forbidding human cloning" establishes the ethical principles that must be accomplished in every research involving human beings. Article 28 of the Law 20.584 "Regulation of the rights and duties of health care users", forbids the participation of handicapped people who cannot express their will in scientific research. Article 13 states that people not related directly with patient care cannot have access to his clinical records (with the exception of people with notarial authorization by the patient). CEISH proposes that, in case of people with intellectual deficiency, the decision to approve a scientific research should be analyzed on an individual basis. If the person is capable of expressing his or her will or has stated his or her consent beforehand, the research can be authorized. If the person cannot express his or her will, the scientific research cannot take place. In prospective studies, a consent from the patient and an authorization of the health authority should be required to access clinical records. In retrospective studies, consent should be obtained from the patient when personal information is going to be used. If the information is nameless, the consent can be disregarded.

No formal epidemiological research based on systematic analysis has focused on the relationship between herpes zoster and immunodeficiency virus (HIV) infection in Taiwan. Our aim was to explore whether herpes zoster is an early manifestation of undiagnosed human HIV infection in Taiwan. This was a retrospective cohort study using the database of the Taiwan National Health Insurance Program. A total of 35,892 individuals aged ≤ 84 years with newly diagnosed herpes zoster from 1998 to 2010 were assigned to the herpes zoster group, whereas 143,568 sex-matched and age-matched, randomly selected individuals without herpes zoster served as the non-herpes zoster group. The incidence of HIV diagnosis at the end of 2011 was estimated in both groups. The multivariable Cox proportional hazards regression model was used to estimate the hazard ratio and 95% confidence interval (CI) for risk of HIV diagnosis associated with herpes zoster and other comorbidities including drug dependence and venereal diseases. The overall incidence of HIV diagnosis was 4.19-fold greater in the herpes zoster group than that in the non-herpes zoster group (3.33 per 10,000 person-years vs. 0.80 per 10,000 person-years, 95% CI 4.04-4.35). The multivariable Cox proportional hazards regression analysis revealed that the adjusted hazard ratio of HIV diagnosis was 4.37 (95% CI 3.10-6.15) for individuals with herpes zoster and without comorbidities, as compared with individuals without herpes zoster and without comorbidities. Herpes zoster is associated with HIV diagnosis. Patients who have risk behaviors of HIV infection should receive regular surveillance for undiagnosed HIV infection when they present with herpes zoster. Copyright © 2015. Published by Elsevier B.V.

Multifocal epithelial hyperplasia (MEH) is a disease of the oral mucosa. Human papillomaviruses 13 and 32 have been detected in these lesions. We describe the epidemiology and clinical characteristics of patients with MEH in a rural community in the Mayan area of Mexico with 53 cases and 54 controls. Clinical and epidemiological data were collected through a direct interview. Oral cell samples were collected with a cytobrush. Subjects collected their own saliva sample in a sterile bottle. All samples were tested for HPV 13 and 32 by polymerase chain reaction using specific primers. Of the 53 patients and 54 healthy subjects, 56% were < 12 years old, 25% were males and 75% females. Evolution of the lesions was between two months and 17 years. The lesions affected lips, jugal mucosa, and tongue, 96% had multiple lesions. From 53 patients, fifty samples of oral cells and 31 samples of saliva were analyzed. HPV 13 was detected in 100% oral cell and 100% saliva samples studied. 16 healthy subjects were HVP 13 positive. A highly significant association of HPV 13 infection and MEH was found, as determined by chi square test (p = 0.00) Household transmission of HPV 13 may happen through saliva and the shared use of contaminated objects.

Similar to human breast cancer mammary tumors of the female dog are commonly associated with a fatal outcome due to the development of distant metastases. However, the molecular defects leading to metastasis are largely unknown and the value of canine mammary carcinoma as a model for human breast cancer is unclear. In this study, we analyzed the gene expression signatures associated with mammary tumor metastasis and asked for parallels with the human equivalent. Messenger RNA expression profiles of twenty-seven lymph node metastasis positive or negative canine mammary carcinomas were established by microarray analysis. Differentially expressed genes were functionally characterized and associated with molecular pathways. The findings were also correlated with published data on human breast cancer. Metastatic canine mammary carcinomas had 1,011 significantly differentially expressed genes when compared to non-metastatic carcinomas. Metastatic carcinomas had a significant up-regulation of genes associated with cell cycle regulation, matrix modulation, protein folding and proteasomal degradation whereas cell differentiation genes, growth factor pathway genes and regulators of actin organization were significantly down-regulated. Interestingly, 265 of the 1,011 differentially expressed canine genes are also related to human breast cancer and, vice versa, parts of a human prognostic gene signature were identified in the expression profiles of the metastatic canine tumors. Metastatic canine mammary carcinomas can be discriminated from non-metastatic carcinomas by their gene expression profiles. More than one third of the differentially expressed genes are also described of relevance for human breast cancer. Many of the differentially expressed genes are linked to functions and pathways which appear to be relevant for the induction and maintenance of metastatic progression and may represent new therapeutic targets. Furthermore, dogs are in some aspects suitable as a

We describe here an extension of a previous genetic characterization of Trypanosoma cruzi strains (Be-62 and Be-78) isolated from the patient Berenice, the first human case of Chagas disease [Chagas, C., 1909. Nova Tripanomíase humana. Estudos sobre morfologia e o ciclo evolutivo do Schizotrypanum cruzi, n. gen., n. sp., agente etiolójico da nova entidade morbida do homem. Mem. Inst. Oswaldo Cruz 1, 159-218]. We wanted to verify the composition of T. cruzi populations originated from these two isolates. In the present work, 22 enzymatic loci (MLEE), nine RAPD primers and 7 microsatellite loci were analyzed. Clones from both strains were also characterized to verify whether these strains are mono or polyclonal. Be-62 and Be-78 strains were different in 3 out of 22 enzymatic systems, in 3 out of 9 RAPD primers tested and in all microsatellite loci investigated. However, our data suggests that both strains are phylogenetically closely related, belonging to genetic group 32 from Tibayrenc and Ayala [Tibayrenc, M., Ayala, F.J., 1988. Isoenzime variability in Trypanosoma cruzi, the agent of Chagas' disease: genetical, taxonomical, and epidemiological significance. Evolution 42, 277-292], equivalent to zymodeme 2 and T. cruzi II major lineage which, in Brazil, comprises parasites from the domestic cycle of the disease. Microsatellite analyses showed differences between the parental strains but suggested that both populations are monoclonal since each strain and their respective clones showed the same amplification products.

Cloning is commonly perceived as a means of generating genetically identical individuals, but it can also be used to obtain genetically matched embryo-derived stem cells, which could potentially be used in the treatment of patients. A recent report offers the first 'proof of principle' of such cloning for therapeutic purposes, referred to as nuclear transplantation to produce stem cells for autologous transplantation.

This study aims to investigate the variation of air pollutants associated with the quarry activities prior to classified distance from quarry site. Air pollutants were monitored with the use of instruments which are Rae System Multirae Lite Pumped (PGM-6208) to measure indoor air quality while TSI 8533 Dusttrack Drx Desktop Aerosol Monitor to measure outdoor air quality. Sampling will be replicated two times. The locations of quarry are at Bandar Saujana Putra and Taman Kajang Perdana 2, Selangor. The objectives of this study are to investigate the impact of quarry mining by preparing the suitable Indoor Air Quality Index and to prepare preventive measure for residential that caused from quarry mining activities. Both Qualitative and Quantitative approaches will be implemented in this study, which employed case study and interview survey. Both quarries identified previously will be the main case study. The Respondent’s interviews are from Local Authority and Quarry Management Staff while questionnaire surveys from selected residences. Measurement method will be used to measure the Particle Matter (PM2.5) for indoor and outdoor in selected resident’s area. However, this paper is primed to discuss the method used in this study. It is not only presents the beneficial information for future research on methodologies employed but also it is anticipated the benefit to environment which can increased residents’ well-being in the vicinity of quarry sites.

Full Text Available Women have a higher proportion of body fat compared to men. However, women consume fewer kilojoules per kilogram lean mass and burn fat more preferentially during exercise compared with men. During gestation, women store even greater amounts of fat that cannot be solely attributed to increased energy intake. These observations suggest that the relationship between kilojoules consumed and kilojoules utilised is different in men and women. The reason for these sex differences in energy metabolism is not known; however, it may relate to sex steroids, differences in insulin resistance, or metabolic effects of other hormones such as leptin. When considering lifestyle modifications, sex differences in energy metabolism should be considered. Moreover, elucidating the regulatory role of hormones in energy homeostasis is important for understanding the pathogenesis of obesity and perhaps in the future may lead to ways to reduce body fat with less energy restriction.

Climate change has substantial impacts on public health and safety, disease risks and the provision of health care, with the poor being particularly disadvantaged. Management of the associated health risks and changing health service requirements requires adequate responses at local levels. Health-care providers are central to these responses. While climate change raises ethical questions about its causes, impacts and social justice, medicine and bioethics typically focus on individual patien...
Full Text Available Phenotypic manifestations of infectious diseases are closely related to individual immune responses. Methods to extract information from patients’ own immune reactions would be of great use for both diagnosis and treatment. Dengue fever is one of the diseases that clinical aggravations could occur paradoxically after humoral immunity appears. This property makes dengue fever an excellent disease model to explore. A principal component analyses (PCAs-based framework derived from a prior vaccination study was developed. The framework was verified by successful demonstrations of known IgG signatures from a Mexico Dengue data set. Afterward the pipeline was tested upon de novo IgG and IgA libraries of Dengue patients from southern Taiwan. We discovered four infection signatures within IgG repertoires, two of which were identical to previous reports. However, it was IgA but not IgG that could differentiate hemorrhagic from non-hemorrhagic patients. IgA repertoires were found more diversified among bleeders, from whom seven signature clusters were characterized. The expressions of transforming growth factor beta 1 (TGFβ1 and accordingly mediated class-switch activity of IgA were distinct only among the PCA-segregated bleeding group. In sum, intercontinental sharing of IgG signatures in dengue fever was demonstrated via a unified working flow. Differential regulation of IgA class-switch with associated diversity expansion plus existences of hemorrhage-restricted clusters were shown. The ability of the framework to find common IgG signatures would implicate applications to infections even from unknown pathogens. The clusters within IgA repertoires could offer perspectives to other IgA-related bleeding disorders such as Henoch-Schönlein purpura or IgA nephropathy. Substantiated grounds for IgA-specific effector function via TGFβ1-mediated class-switch would be a new factor to consider for infectious diseases.
The library is launching a 'sharing resources@CERN' campaign, aiming to increase the library's utility by including the thousands of books bought by individual groups at CERN. This will improve sharing of information among CERN staff and users. Until now many people were unaware that copies of the same book (or standard, or journal) are often held not only by the library but by different divisions. (Here Eduardo Aldaz, from the PS division, and Isabel Bejar, from the ST division, read their divisional copies of the same book.) The idea behind the library's new sharing resources@CERN' initiative is not at all to collect the books in individual collections at the CERN library, but simply to register them in the Library database. Those not belonging to the library will in principle be unavailable for loan, but should be able to be consulted by anybody at CERN who is interested. "When you need a book urgently and it is not available in the library,' said PS Division engineer Eduardo Aldaz Carroll, it is a sham...
Full Text Available In this paper one of human characteristic namely beyond abstract status is studied from view point of two great philosophers: Mulla Sadra and Mulla Hadi Sabzewari. In philosophic knowledge of human being, transcendental theosophy and its commentators, have paid a particular attention to this certain status and have proved its bases. In this article , opinions of Mulla Sadra and Mulla Hadi Sabzewari on this status are studied and it is concluded that from viewpoint of these two sages, human being, having no determined status, can pass all stages and reach to a stage that is abstract of both: matter and quality. Although these two sages demonstrate and express this subject in a little different ways and this lead them to two different horizon of vision about this status.
This study examined the relationship among human relations in the workplace, job involvement, affective commitment and continuance commitment with occupational and organizational commitment, and well-being. Questionnaires were completed by 855 female nurses who worked in four public hospitals (mean age = 32.6 years). The results of factor analysis showed that each component of the vocational constructs was distinguishable from the others. Path analysis showed that human relations in the workplace directly influenced job involvement and affective commitment both to the occupation and to the organization. Job involvement in turn directly influenced affective commitment and continuance commitment to the occupation. Job involvement also influenced affective commitment to the organization directly, and indirectly through affective commitment to the occupation. Finally, it was found that human relations in the workplace and affective commitment to the occupation positively influenced well-being; continuance commitment to the occupation was a negative influence. Theoretical and practical implications are discussed.
Full Text Available Objectives. Functional components in alliums have long been maintained to play a key role in modifying the major risk factors for chronic disease. To obtain a better understanding of alliums for chronic disease prevention, we conducted a systematic review for risk factors and prevention strategies for chronic disease of functional components in alliums, based on a comprehensive English literature search that was conducted using various electronic search databases, especially the PubMed, ISI Web of Science, and CNKI for the period 2007–2016. Allium genus especially garlic, onion, and Chinese chive is rich in organosulfur compounds, quercetin, flavonoids, saponins, and others, which have anticancer, preventive cardiovascular and heart diseases, anti-inflammation, antiobesity, antidiabetes, antioxidants, antimicrobial activity, neuroprotective and immunological effects, and so on. These results support Allium genus; garlic and onion especially may be the promising dietotherapeutic vegetables and organopolysulfides as well as quercetin mechanism in the treatment of chronic diseases. This review may be used as scientific basis for the development of functional food, nutraceuticals, and alternative drugs to improve the chronic diseases.
In his 1785-review of the Ideen zur Philosophie der Geschichte der Menschheit, Kant objects to Herder's conception of nature as being imbued with active forces. This attack is usually evaluated against the background of Kant's critical project and his epistemological concern to caution against the "metaphysical excess" of attributing immanent properties to matter. In this paper I explore a slightly different reading by investigating Kant's pre-critical account of creation and generation. The aim of this is to show that Kant's struggle with the forces of matter has a long history and revolves around one central problem: that of how to distinguish between the non-purposive forces of nature and the intentional powers of the mind. Given this history, the epistemic stricture that Kant's critical project imposes on him no longer appears to be the primary reason for his attack on Herder. It merely aggravates a problem that Kant has been battling with since his earliest writings. Copyright © 2016 Elsevier Ltd. All rights reserved.

Full Text Available This paper draws on Martha Nussbaum’s account of the nature of human well-being to explore the role of animals in formal education settings. Nussbaum equates well-being with human flourishing, and argues that people live well when engaged in essential functions that are particular capabilities, each a necessary but insufficient contributor to well-being. One of these capabilities is the ability to “to have concern for and live with other animals, plants and the environment.” Yet, this condition of well-being remains largely unexplored among in education. In recent years, the benefits of human-animal interaction in education settings has been researched and discussed in the social sciences, particularly the use of dogs to aid reluctant readers in literacy development, and the use of therapy dogs in universities during final examination blocks. This paper presents findings of one particular research project of the effects of a unique, Canadian school-based cooperative education program, “Under One Woof,” in which students work with animals. Based on interviews, students’ own stories of the impact of animal interaction – particularly in light of other challenges they faced academically and socially – appear to support other empirical accounts of positive effects of animals in education settings, and offer insight into the nature and effects of human-animal interaction as an element of well-being.
