Universal Human Rights and the Problem of Unbounded Cultural Meanings

Freedom from violence stands as an important candidate for a universal human right. By definition, however, such rights apply only to phenomena that are universally perceived and experienced and take predictable expression, a possibility that many contemporary interpretations of cultural theory reject. Yet people who live dramatically different lives—on tourist islands in the West Indies or as hunter-gatherers and reindeer herders in Arctic regions—agree about components that comprise a unitary phenomenon legitimately called "violence." This is consistent with findings from cognitive and neruological science and with a more Geertzian theory that culture understood as meaning is not a thing, cultural variability occurs between individuals, and cultural consensus emerges as a necessary consequence of social interaction among people who participate in common social fields, who engage in common social discourse.     

The true body shape of rorqual whales

Live Sei and Minke whales were observed underwater off Japan by a new method using commercial catcher boats. A non-explosive harpoon was fired into the tail region of a whale and a diver approached the "tethered" live whale.
After initial flurries, Sei and Minke whales swam steadily ahead of the catcher and could easily be approached by a diver. They took absolutely no notice of the diver. Live Sei and Minke whales kept their mouths tight shut all the time, but immediately after death the lower jaw always fell open. Little blood was emitted from the harpoon wound. The flippers were raised laterally when a whale surfaced and held against the sides of the body when it dived.
The body shape of both rorqual species was streamlined and the throat region was quite flat, not in any way dilated. The classical baggy-throated illustrations of rorqual whales do not show the true shape of live animals.
Sperm whales harpooned by the same method swam about wildly, shed much blood and could not be observed underwater.     

Porphyrins as early biomarkers for arsenic exposure in animals and humans.

We studied the effect of arsenic exposure on the haem biosynthetic pathway in the rat and humans. Significant increases in protoporphyrin IX, coproporphyrin III, coproporphyrin I were observed in the blood, liver and kidney, and in the urine of rats after a single dose of arsenic. The level of increase was dependent on the arsenic species present. Most of porphyrin concentrations in the tissues increased within 24 hr and urinary excretion elevated within 48 hr. In the human study, we collected urine samples from 113 people who live in Xing Ren of Guizhou Province, a coal-borne arsenicosis endemic area in southwest of PR China and from 30 people who live in Xing Yi (about 80 km southwest of Xing Ren) where arsenicosis is not prevalent. We analyzed the urinary porphyrins using HPLC. Results indicate that all urinary porphyrins were higher in the arsenic exposed group than those in the control group. Women, children and older age people spend much of their time indoors, they had greater increases of urinary arsenic and porphyrins. They were the higher risk groups among the study subjects. A positive correlation between the urinary arsenic levels and porphyrin concentrations demonstrated the effect of arsenic on haem biosynthesis. Significant alteration in the porphyrin excretion profiles of the younger age (<20 y) arsenic exposed group suggested that porphyrins could be used as early warning biomarkers for chronic exposure to arsenic.     

笼捕法和陷阱法对森林小型兽类多样性监测效率比较

<正>小型兽类包括食虫目(Insectivora)、啮齿目(Rodentia)、翼手目(Chiroptera)、兔形目(Lagomorpha)等,物种数量多,分布广,适应能力强,对环境变化敏感,因此其群落组成和种群数量变化可较好地反映生境变化的质量和人类活动的干扰程度(肖治术等,2002;李俊生等,2003;仝磊和路纪琪,2010)。小型兽类多样性一直是生物多样性和生态环境监测与评价的重要指示类群之一(周立志和马勇,2002)。统计动物毛发、粪便、巢穴、叫声、足迹等动物痕迹以及直接观察等方法已被广泛用于兽类物种监测和种群密度估计(Eberhardt and Van Etten,1956;Bider,1968;Gannon     

Organ transplantation in Nepal: Ethical,legal, and practical issues

In Nepal, live donor organ transplantation is only 14 years old with the first successful kidney transplant made in 2008 and a successful liver and bone marrow transplant made in 2016. However, transplantation of cadaveric cornea dates back to 1998. There are still no cases of animal-to-human organ transplantation in Nepal. There are stringent laws to regulate human body organ transplantation in Nepal which are amended from time to time. However, there is a racket of human traffickers who lure rural people from this low-income country into the illegal organ trade. Furthermore, there is a substantial lack of awareness of organ donation among the general public. This article focuses on the stipulations of ethical, legal, and practical issues of obtaining organs procured from living and brain-dead donors that support the process of transplantation in Nepal. In addition, the article also explores the legal and practical issues of organ trafficking and organ donation awareness in Nepal on the basis of factual data and findings from other studies.     

A nonapoptotic cell death process, entosis, that occurs by cell-in-cell invasion

Epithelial cells require attachment to extracellular matrix (ECM) to suppress an apoptotic cell death program termed anoikis. Here we describe a nonapoptotic cell death program in matrix-detached cells that is initiated by a previously unrecognized and unusual process involving the invasion of one cell into another, leading to a transient state in which a live cell is contained within a neighboring host cell. Live internalized cells are either degraded by lysosomal enzymes or released. We term this cell internalization process entosis and present evidence for entosis as a mechanism underlying the commonly observed "cell-in-cell" cytological feature in human cancers. Further we propose that entosis is driven by compaction force associated with adherens junction formation in the absence of integrin engagement and may represent an intrinsic tumor suppression mechanism for cells that are detached from ECM.     

Health care rationing: the public's debate.

OBJECTIVE--To elicit the views of a large nationally representative sample of adults on priorities for health services. DESIGN--An interview survey based on a random sample of people aged 16 and over in Great Britain taken by the Office of Population Censuses and Surveys. SUBJECTS--The response rate to the survey was 75%, and the total number of adults interviewed was 2005. MAIN OUTCOME MEASURES--A priority ranking exercise of health services supplemented with attitude questions about priorities, who should set priorities, and budget allocation. RESULTS--The results of the main priority ranking exercise of 12 health services showed that the highest priority (rank 1) was accorded to "treatments for children with life threatening illness," the next highest priority (rank 2) was accorded to "special care and pain relief for people who are dying." The lowest priorities (11 and 12) were given to "treatment for infertility" and "treatment for people aged 75 and over with life threatening illness." Most respondents thought that surveys like this one should be used in the planning of health services. CONCLUSIONS--The public prioritise treatments specifically for younger rather than older people. There is some public support for people with self inflicted conditions (for example, through tobacco smoking) receiving lower priority for care, which raises ethical issues.     

Commercialization of basic research from within the university and return of value to the public

The responsibility to return "value" to those who support basic research is an obligatory part of accepting funds to support the research. This reality should, but now does not, impact planning and execution of all basic research from its earliest stages. Universities are becoming ever more important in their role in the accelerating quest of a national goal of transition to a "knowledge-based economy." As such, the complex organizational format of a university, laden with entrenched procedures of questionable utility, should be adjusted to identify the means to commercialize the small subset of projects that appear suitable for further development. Of special concern is the growing tendency to encourage academic "innovators" to develop spin-out companies "on the side." While seductive in perceived simplicity, this is a difficult step and we believe that most such individuals are ill-suited to these activities. Not because of technical ability but because of lack of relevant management experience. We attempt to address that situation through a brief listing of some reasons why people "do research" and outline phases (steps) in moving from concept to application, including an overview of start-up and funding early-stage spin-outs. A discussion of the limits to applying results of basic research to enhancing sperm fertility in commodity and companion animals and humans is provided. Hurdles are so daunting that there is concern as to why anyone would attempt to translate basic observations into practical solutions; which in turn raises the question of why funding agencies should fund basic studies in the first place.     

Environmental migrants,structural injustice,and moral responsibility

Climate change and environmental problems will force or induce millions of people to migrate. In this article, I describe environmental migration and articulate some of the ethical issues. To begin, I give an account of these migrants that overcomes misleading dichotomies. Then, I focus attention on two important ethical issues: justice and responsibility. Although we are all at risk of becoming environmental migrants, we are not equally at risk. Our risk depends on our temporal position, geographical location, social position, and the kind of society in which we live. We all contribute to environmental problems, but we do not contribute equally. About 11% of the world population is responsible for 50% of carbon emissions. These inequalities raise issues of justice because many of the people who are at high risk have contributed little to the problems. Since the issues of justice are relatively clear and compelling, I focus more attention on issues of responsibility. I use Iris Marion Young’s account of responsibility for structural injustice to address four key questions about moral responsibility and environmental migration.     

Life-history correlates of the evolution of live bearing in fishes

Selection for live bearing is thought to occur when the benefits of increasing offspring survival exceed the costs of reduced fecundity, mobility and the increased metabolic demands of carrying offspring throughout development. We present evidence that live bearing has evolved from egg laying 12 times in teleost (bony) fishes, bringing the total number of transitions to 21 to 22 times in all fishes, including elasmobranchs (sharks and rays). Live bearers produce larger offspring than egg layers in all of 13 independent comparisons for which data were available. However, contrary to our expectation there has not been a consistent reduction in fecundity; live bearers have fewer offspring in seven out of the 11 available comparisons. It was predicted that live bearers would have a larger body size, as this facilitates accommodation of developing offspring. This prediction was upheld in 14 out of 20 comparisons. However, this trend was driven by elasmobranchs, with large live bearers in seven out of eight comparisons. Thus, while the evolution of live bearing in elasmobranchs is correlated with predicted increases in offspring size and adult size, teleost live bearers do not have such a consistent suite of life-history correlates. This suggests that constraints or selection pressures on associated life histories may differ in live-bearing elasmobranchs and teleost fishes.     

Illumination of the malaria parasite Plasmodium falciparum alters intracellular pH. Implications for live cell imaging

Live cell fluorescence microscopy has been widely used to study physiological processes in the human malarial parasite Plasmodium falciparum, including pH homeostasis, Ca(2+) signaling and protein targeting. However, the reproducibility of the data is often poor. Controversial statements exist regarding cytosolic and vacuolar baseline pH, as well as regarding the subcellular localization of some of the fluorochromes used. When trying to reproduce published baseline values, we observed an unexpected light sensitivity of P. falciparum, which manifests itself in the form of a strong cytoplasmic acidification. Even short exposure times with moderate to low light intensities caused the parasite cytosol to acidify. We show that this effect arises from the selective disruption of the parasite's acidic food vacuole, brought about by lipid peroxidation initiated by light-induced generation of hydroxyl radicals. Our data suggest that heme serves as a photosensitizer in this process. Our findings have major implications for the use of live cell microscopy in P. falciparum and add a cautionary note to previous studies where live cell fluorometry has been used to determine physiological parameters in P. falciparum.     

A statistical analysis of the effect of warfare on the human secondary sex ratio

Many factors have been hypothesized to affect the human secondary sex ratio (the annual percentage of males among all live births), among them race, parental ages, and birth order. Some authors have even proposed warfare as a factor influencing live birth sex ratios. The hypothesis that during and shortly after periods of war the human secondary sex ratio is higher has received little statistical treatment. In this paper we evaluate the war hypothesis using 3 statistical methods: linear regression, randomization, and time-series analysis. Live birth data from 10 different countries were included. Although we cannot speak of a general phenomenon, statistical evidence for an association between warfare and live birth sex ratio was found for several countries. Regression and randomization test results were in agreement. Time-series analysis showed that most human sex-ratio time series can be described by a common model. The results obtained using intervention models differed somewhat from results obtained by regression methods.     

A new mouse strain manifesting high proteinuria and kidney glomerular defect.

A mutant strain of mice manifesting high proteinuria, wasting syndrome, and kidney glomerular defect was established from the F5 offspring of an interstrain cross of CBA/Nga and RFM/Nga mice. Affected mice had high levels of proteinuria after 40 days of age. The body weight of about 22.6% of affected mice decreased rapidly and they died between 3 and 5 months of age. We learned that this abnormality is controlled by two pairs of autosomal recessive genes; the mutant strain of mice is designated FGS/Nga. The mutant strain has been characterized by high proteinuria and renal lesions with focal sclerosis of glomeruli and tubular atrophy with interstitial nephritis in the kidney resembling the human disease. The FGS/Nga mouse strain is a potential animal model for studying kidney glomerular defect in humans.

"The Divine Impatience": Ritual, Narrative, and Symbolization in the Practice of Martyrdom in Palestine

Violence is obscured by habits of thought, which predispose us to reject that which falls outside of our notion of "normal' human behavior. By dismissing as incomprehensible, or "pathologic" embodied practices that do not correspond to a "rationally ordered' everyday life, some anthropologists concerned with issues of violence forsake a fundamental responsibility to foster an understanding of phenomena that affronts, offends, or questions our own cultural norms and assumptions. Situations of violence, whether due to contextual or individual instability, by definition defy pregiven notions of "rationality" and "normal behavior." This article is about Palestinian martyrs, youths killed in confrontations with the Israeli military. It seeks to identify the cultural and psychological processes that make Palestinian martyrdom possible within the specific context of Israeli military occupation. It elaborates the ritual, narrative, and symbolic dimensions of a practice that exists within a Palestinian discourse of sacrifice and of national liberation.

Predicting the effects of chlorine on the micro-organisms of filamentous bulking activated sludges

Rapid and definite assessment of the effect that a specific biocide has on a specific case of filamentous bulking sludge is a much-needed tool in activated sludge wastewater treatment. The Live/Dead stain (LIVE/DEAD BacLight) distinguishing "living" and "non-living" cells, a nitrifying activity (NA) test and the oxygen uptake rate (OUR) measurement were examined for their appropriateness to predict the effects of chlorine on filamentous bulking sludges. The study showed the live/dead stain to be relevant for revealing the specific effect of chlorine on the filamentous bacteria of a bulking sludge. However, using live/dead stain alone for the determination of the appropriate chlorine dose against bulking may lead to an underestimation of the damage caused by chlorine to the useful microorganisms in the flocs. Indeed, using the live/dead stain, it was not easy to distinguish dead cells caused by chlorination from those originally present in the flocs The NA test was the most sensitive in detecting damage caused by chlorine to the floc-forming microorganisms. Therefore, for a safer determination of the chlorine dose effective against bulking and protective of the microbial activity of the sludge, the results of this study suggest coupling of the live/dead stain with the NA test and/or the OUR test.     

Genetic Testing for Huntington's Disease: How Is the Decision Taken?

Research on genetic decision-making normally constructs the decision as an opportunity for choice. However, minimal research investigates how these decisions are taken and whether those who live with genetic risk perceive the test as an opportunity for choice. Employing semistructured interviews with at-risk persons, this study explored decisions about genetic testing for Huntington's disease (HD)--a fatal genetic disorder. A primary aim was to understand how test decisions were perceived. Qualitative data analysis revealed four decision pathways: (1) no decision to be made, (2) constrained decisions, (3) reevaluating the decision, and (4) indicators of HD. Contrary to the rational, "information-processor" approach to decision making, some test decisions were immediate and automatic. These stories challenged the conventional construction of a genetic-test decision as an opportunity for choice. Participant narratives suggested that this construction may be inadequate, at least for some people who live with genetic risk. Test decisions were sometimes constrained by perceived responsibility to other family members, notably offspring. For others at risk, the test decision was a dynamic process of critical thought and evaluation. Finally, behaviors that could be symptoms of HD were the catalyst for testing.     

The use of mortality data in setting priorities for disease prevention

The examination of specific disease mortality by five-year age groups helps identify health problems as problems of people and how they live. Traditional methods of examining data in broad classifications tend to obscure etiological factors and the importance of behaviour. Violence, a major cause of death in young adults, gives way to so-called diseases of indulgence in middle age, especially among men who have a much higher death rate than women. Male life expectancy at age 40 has increased only marginally in the past 40 years. Health-related human behaviour must be considered within an ecological framework since social, cultural and physical environmental differences as well as personal factors influence life-style. The responsibility for prevention rests more with the individual and society at large than with health workers. Probability tables, Health Hazard Appraisal (a system of personal risk assessment) and personal counselling can reinforce healthful life-styles and help correct hazardous ones.     

Take a stand commentary: how can medical anthropologists contribute to contemporary conversations on "illegal" im/migration and health?

Of the estimated 214 million people who have migrated from poorer to richer countries in search of a better life, between 20 and 30 million have migrated on an unauthorized, or "illegal," basis. All have health needs, or will in the future, yet most are denied health care available to citizens and authorized residents. To many, unauthorized im/migrants' exclusion intuitively "makes sense." As scholars of health, social justice, and human rights, we find this logic deeply flawed and are committed to advancing a constructive program of engaged critique. In this commentary, we call on medical anthropologists to claim an active role in reframing scholarly and public debate about this pressing global health issue. We outline four key theoretical issues and five action steps that will help us sharpen our research agenda and translate ourselves for colleagues in partner disciplines and for broader audiences engaged in policymaking, politics, public health, and clinical practice.     

Child Soldiers, International Humanitarian Law, and the Globalization of Childhood

This article reviews the development of the laws and treaties regulating the use of child soldiers and the political, social, and cultural context in which these developments are grounded. Humanitarian and human rights groups have undertaken a major initiative to end the use of young combatants. These efforts are part of a larger children's human rights project designed to create a universal definition of "childhood." Casting the proposed ban on child soldiers in the language of human rights deflects attention from the enormity of the social and cultural changes involved in the proposed transnational restructuring of age categories. Treaty-making efforts reflect an emerging "politics of age" that shapes the concept of "childhood" in international law, and in which different international, regional, and local actors make use of age categories to advance particular political and ideological positions.
