    AN INCREASINGLY COMMON ENVIRONMENTAL HEALTH PROBLEM: Complaints related to indoor environment represent one of the most frequent problems that environmental health practitioners are confronted with. Hence the incidence of the Sick Building Syndrome (SBS) has been increasing since the Seventies. DIFFERING DEFINITIONS AND CLINICAL PRESENTATIONS: The WHO defines SBS as an excess of complaints and symptoms occurring in certain occupants of non-industrial buildings. The syndrome can only be evoked after elimination in the person concerned of a disease related to the building, the aetiological agent of which is identifiable. The symptoms described during SBS (headaches, concentration problems, asthenia, irritation of the skin or nasal mucosa, of the eyes and upper respiratory tract.) are non specific and frequently observed in the general population. AN UNKNOWN CASE, BUT NUMEROUS AETIOLOGICAL FACTORS SUSPECTED: There is no unanimously accepted definition nor physio-pathological theory to explain the occurrence of SBS in a particular building. Many favouring factors, including the type and rate of ventilation, volatile organic compounds, particles and humidity have been suspected. TECHNICAL, SOCIAL, AND MEDICAL MANAGEMENT IS REQUIRED: Although the symptoms are benign, they can be uncomfortable or even handicapping and prevent the functioning of workplaces. The SBS, the social and economical costs of which are high, requires multidisciplinary management. PMID:14576597

  4. Binary Stars in SBS Survey

    NASA Astrophysics Data System (ADS)

    2016-06-01

    Thirty spectroscopic binary stars were found in the Second Byurakan Survey (SBS). They show composite spectra - WD(DA)+dM or dC (for example Liebert et al. 1994). They may have red color, if the radiation of the red star dominates, and blue one, if the blue star is brighter and have peculiar spectrum in our survey plate. We obtained slit spectra for most of such objects. But we often see the spectrum of one component, because our slit spectra did not cover all optical range. We examine by eye the slit spectra of all SBS stellar objects (˜700) in SDSS DR7, DR8 or DR9 independent on our observations. We confirmed or discovered the duplicity of 30 stars. Usually they are spectroscopic binaries, where one component is WD (DA) and the second one is a red star with or without emission. There also are other components combinations. Sometimes there are emission lines, probably, indicating variable ones.

    We demonstrate a technique for SBS reduction in a nanosecond Yb-fiber amplifier by imposing 1.19 GHz/ns frequency chirp on the seed pulses with a pulse-driven phase modulator. A nearly 9-fold increase in the SBS threshold was observed for 8.4 ns pulses. SBS threshold data and transient SBS gain for various degrees of chirp are reported and compared with theoretical calculations. We further demonstrate the recovery of the input narrowband spectrum by applying an opposite chirp with a second phase modulator after the amplification. PMID:27410540

    This study investigated three questions: (1) What are Lebanese secondary school (Grade 9-12) biology teachers' and university biology professors' positions regarding biological evolution?, (2) How do participants' religious affiliations relate to their positions about evolutionary science?, and (3) What are participants' positions regarding evolution education? Participants were 20 secondary school biology teachers and seven university biology professors. Seventy percent of the teachers and 60% of the professors were Muslim. Data came from semi-structured interviews with participants. Results showed that nine (Christian or Muslim Druze) teachers accepted the theory, five (four Muslim) rejected it because it contradicted religious beliefs, and three (Muslim) reinterpreted it because evolution did not include humans. Teachers who rejected or reinterpreted the evolutionary theory said that it should not be taught (three), evolution and creationism should be given equal time (two), or students should be allowed to take their own stand. Two professors indicated that they taught evolution explicitly and five said that they integrated it in other biology content. One Muslim professor said that she stressed 'the role of God in creation during instruction on evolution'. It seems that years of studying and teaching biology have not had a transformative effect on how a number of teachers and professors think about evolution.

  1. Prescreening bacterial colonies for bioactive molecules with Janus plates, a SBS standard double-faced microbial culturing system.

    Despite the availability of many culture-based antibiotic screening methods, the lack of sensitive automated methods to identify functional molecules directly from microbial cells still limits the search for new biologically active compounds. The effectiveness of antibiotic detection is influenced by the solubility of the assayed compounds, indicator strain sensitivity, culture media and assay configuration. We describe a qualitative high throughput screening system for detecting cell-perturbing molecules from bacterial colonies employing two opposed agar layers sequentially formed in prototype Society for Biomolecular Screening (SBS) plates, named Janus plates. Direct assay of microbial colonies against target organisms in opposed agar layers overcomes some of the limitations of agar overlay methods. The system enables the rapid detection of extracellular cell-perturbing molecules, e.g., antibiotics, excreted directly from environmental isolates. The source bacterial colonies remain separate from the target organism. The growth layer is prepared and grown independently, so environmental strains can be grown for longer intervals, at temperatures and in media that favor their growth and metabolite expression, while the assay layer with pathogens, usually requiring nutrient-rich medium and elevated temperatures, are added later. Colonies to be tested can be precisely arrayed on the first agar surface, thus avoiding dispersion and disturbance of potential antibiotic-producing colonies by overlaying agar with the target strain. The rectangular SBS configuration facilitates factorial replication of dense microbial colony arrays for testing with multiple assays and assay conditions employing robotic colony pickers and pin tools. Opposed agar layers only slightly reduced the effectiveness for detecting growth inhibition from pure antibiotics compared to single-layer agar diffusion assays. The Janus plate enabled an automation-assisted workflow where a lone operator can

    The 6-m telescope was used in conjunction with a scanner (IPCS) and the SP-124 spectrograph to make an investigation with resolution approx. 3.5 A of three new quasars: SBS 0953 + 549 (z/sub e/ = 2.580), SBS 1116 + 603 (z/sub e/ = 2.628), and SBS 1138 + 584 (z/sub e/ = 1.699). The spectra of these quasars are analyzed. The emission line L/sub approx./ in the quasar SBS 1116 + 603 may have a two-component structure: a narrow peak (FWHM a 3000 km/sec) and a broad pedestal (FWHM a 19,400 km/sec). In the quasar SBS 0953 + 549, the profile of the emission line L/sub approx./ recalls the profiles of P Cyg type lines, which are observed in the spectra of stars with expanding shells; two strong (tau approx. 1) and broad (FWHM approx. 1700 and 1000 km/sec) absorption lines with z/sub a/ = 2.451 and 2.503 have been found and identified as L/sub approx./ lines. The symmetric profiles of these lines correspond to N(HI) approx. 10/sup 20/ cm/sup -2/ for the cloud with z/sub a/ = 2.541 and 5 x 10/sup 19/ cm/sup -2/ for the cloud with z/sub a/ = 2.503. The authors have also estimated the line-of-sight densities of heavy elements found at z/sub a/ = 0.3800 (SBS 0953 + 549) and z/sub a/ = 1.4082 (SBS 1138 + 584). The densities of the absorption details in these and other known quasars are compared.

    A new technique for mitigating stimulated Brillouin scattering (SBS) effects in narrow-linewidth Yb-doped fiber amplifiers is demonstrated with a model that reduces to solving an 8×8 system of coupled nonlinear equations with the gain, SBS, and four-wave mixing (FMW) incorporated into the model. This technique uses two seed signals, or 'two-tones', with each tone reaching its SBS threshold almost independently and thus increasing the overall threshold for SBS in the fiber amplifier. The wavelength separation of these signals is also selected to avoid FWM, which in this case possesses the next lowest nonlinear effects threshold. This model predicts an output power increase of 86% (at SBS threshold with no signs of FWM) for a 'two-tone' amplifier with seed signals at 1064nm and 1068nm, compared to a conventional fiber amplifier with a single 1064nm seed. The model is also used to simulate an SBS-suppressing fiber amplifier to test the regime where FWM is the limiting factor. In this case, an optimum wavelength separation of 3nm to 10nm prevents FWM from reaching threshold. The optimum ratio of the input power for the two seed signals in 'two-tone' amplification is also tested. Future experimental verification of this 'two-tone' technique is discussed.

    Racial differentials in mortality provide important insight into the nature of mass disease in capitalist society. Not only are the differentials sizable in magnitude, they are consistent for multiple causes of death and appear to evolve in response to social development. The relationships among social factors and the biological and physical agents of disease can be identified through racial contrasts and a pattern of causation which applies to both the minority and majority populations described. Furthermore, the impact of exploitation as the primary disease-mediating factor under capitalist social relations can be estimated. This paper attempts to combine an analysis of bio-medical mechanisms with Marxist social theory in a comprehensive framework for the study of the social origins of racial differentials.

    The Society for Developmental Biology 64th annual meeting took place by the beautiful San Francisco Bay from July 27th to August 1st, 2005. Organized under the leadership of Judith Kimble (SDB President, U. Wisconsin-Madison), the meeting attracted over one thousand developmental biologists from all over the world. They gathered to present data, exchange ideas and enjoy basking in the warm sun on the piers. Strong themes emerged from the diverse subjects discussed at the meeting, demonstrating exciting trends towards the unifying goal of understanding the progression from a single cell to an adult organism. Cell and Tissue Polarity was a recurring topic at the meeting. Questions like "is there polarity", "how is it achieved" and "how is it linked to stem cell maintenance" were discussed. Post-transcriptional regulation involving protein degradation and microRNA (miRNA) modulation of gene expression was featured in the context of transition between meiosis to mitosis and asymmetries in the embryo. It is apparent that Evolutionary Developmental Biology, once a major driving influence in the early days of the field, continues to enjoy a renaissance as researchers familiar with traditional model organisms are increasingly attracted to the field and as modern genetic and molecular approaches are applied to an increasingly varied assortment of organisms. The attention is beginning to pay off as laboratories are starting to generate significant results shedding light into how developmental programs are altered to generate morphological diversity. In the Satellite Symposium on Plant Development held on July 27th, 2005, the overriding theme was on the identity and maintenance of Stem Cells in Plants. Finally, researchers working on diverse organisms have shown a strong effort to address Developmental Coordination: on the subcellular, cellular and tissue levels. Advanced imaging techniques are combined with traditional genetic methods to scrutinize and compare dynamic

    Objective: The aim was to provide a scholarly review of the published literature on biological, clinical, and nonclinical contributors to race/ethnic and sex disparities in endocrine disorders and to identify current gaps in knowledge as a focus for future research needs. Participants in Development of Scientific Statement: The Endocrine Society's Scientific Statement Task Force (SSTF) selected the leader of the statement development group (S.H.G.). She selected an eight-member writing group with expertise in endocrinology and health disparities, which was approved by the Society. All discussions regarding the scientific statement content occurred via teleconference or written correspondence. No funding was provided to any expert or peer reviewer, and all participants volunteered their time to prepare this Scientific Statement. Evidence: The primary sources of data on global disease prevalence are from the World Health Organization. A comprehensive literature search of PubMed identified U.S. population-based studies. Search strategies combining Medical Subject Headings terms and keyword terms and phrases defined two concepts: 1) racial, ethnic, and sex differences including specific populations; and 2) the specific endocrine disorder or condition. The search identified systematic reviews, meta-analyses, large cohort and population-based studies, and original studies focusing on the prevalence and determinants of disparities in endocrine disorders. Consensus Process: The writing group focused on population differences in the highly prevalent endocrine diseases of type 2 diabetes mellitus and related conditions (prediabetes and diabetic complications), gestational diabetes, metabolic syndrome with a focus on obesity and dyslipidemia, thyroid disorders, osteoporosis, and vitamin D deficiency. Authors reviewed and synthesized evidence in their areas of expertise. The final statement incorporated responses to several levels of review: 1) comments of the SSTF and the

    This brief opinion proposes measures to increase efficiency and exclude errors in biomedical research under the existing dynamic situation.

    1999-03-09

    A stimulated Brillouin scattering (SBS) phase conjugate laser mirror uses a solid-state nonlinear gain medium instead of the conventional liquid or high pressure gas medium. The concept has been effectively demonstrated using common optical-grade fused silica. An energy threshold of 2.5 mJ and a slope efficiency of over 90% were achieved, resulting in an overall energy reflectivity of >80% for 15 ns, 1 um laser pulses. The use of solid-state materials is enabled by a multi-pass resonant architecture which suppresses transient fluctuations that would otherwise result in damage to the SBS medium. This all solid state phase conjugator is safer, more reliable, and more easily manufactured than prior art designs. It allows nonlinear wavefront correction to be implemented in industrial and defense laser systems whose operating environments would preclude the introduction of potentially hazardous liquids or high pressure gases. 8 figs.

    The Second Byurakan Survey (SBS) is a well-known combined survey, which uses the presence of UV-excess radiation in the continuum, or the presence of emission lines in the spectra for the identification of active and star-forming galaxies. This work reports on a comparative study of galaxies identified with UV-excess (UVX), and galaxies identified via emission-line techniques (ELG) in the fields of the SBS. The spectroscopic parameters used for the comparison are the [OII]λ3727Å/Hβ and [OIII]λ5007Å/Hβ emission-line ratios, the equivalent widths of [OII]λ3727Å, [OIII]λ5007Å, and Hβ emission lines. Spectroscopic parameters were determined from the spectra obtained from SDSS DR7. Based on emission line ratios, we have built also diagnostic diagrams to distinguish AGN (Seyferts and LINERs) and SB galaxies.

    2012-01-01

    The history of connective tissue research began in the late 18th century. However, it is only 50 years later that the concept of connective tissue was shaped. It took another fifty years before biochemical knowledge of extracellular matrix macromolecules began to emerge in the first half of the 20th century. In 1962, thanks to Ladislas and Barbara Robert, back from the US, the first society called "French Connective Tissue Club" was created in Paris. The first board was constituted of Albert Delaunay, Suzanne Bazin and Ladislas Robert. Very quickly, under the influence of these pioneers, national and international meetings were organized and, in 1967, a "Federation of the European Connective Tissue Clubs" was created at the initiative of Ladislas Robert (Paris) and John Scott (Manchester). It spread rapidly to the major European nations. In 1982 the transformation of "Clubs" in "Societies" occurred, a name more in line with the requirements of the time. In 2008, the "French Connective Tissue Society" became the "French Society of Extracellular Matrix Biology" ("Société Française de Biologie de la Matrice Extracellulaire", SFBMEc), to better highlight the importance of the extracellular matrix in the biology of living organisms. The SFBMEc's mission today is to promote and develop scientific exchanges between academic, industrial, and hospital laboratories involved in research on the extracellular matrix. SFBMEc organizes or subsidizes scientific meetings and awards scholarships to Ph.D. students or post-docs to participate in international conferences. It includes 200 to 250 members from different disciplines, developing strong interactions between scientists, clinicians and pathologists. It is present all around the French territory in many research laboratories. During these last 50 years, the extraordinary advances made possible by the development of new investigation techniques, in particular molecular biology, cell and tissue imaging, molecular modeling

    An approach that introducing a standing wave into focal area to stabilize the output energy and duration of stimulated Brillouin scattering (SBS) compression is presented. An interferometric scheme filled with FC-770 is used to improve the stability of both output energy and duration two times compared with an equivalent conventional SBS compressor. Moreover, the interferometric scheme shows a promotion for the performance of SBS compression.

    The present work has the objective of analyzing blends of PP with 30 wt% SBS vulcanized with gamma irradiation. In order to do so, SBS was irradiated at 10, 25 and 50 kGy with gamma rays. Results indicate that the gel fraction increases with irradiation dose, varying from 0.3% to 13.0% for the doses employed. Concerning tensile properties, it can be seen that the incorporation of SBS non-irradiated or irradiated decreases Young's modulus, while increasing elongation at break. Respect to thermal studies, it was detected that SBS decreases melting enthalpy of blends, fact that implies a decrease on crystallinity degree, being this effect more noticeable when SBS is irradiated at doses higher than 10 kGy. On the other hand, melting temperature diminishes slightly when adding SBS to PP, but does not show significant variations when SBS is irradiated. PPs MFI decreased with the addition of SBS, being the effect more notorious with irradiation dose. Finally, it can be concluded that SBS can be vulcanized by gamma irradiation, and that the crosslinking degree increases with irradiation dose.

    Oxidative ageing as an inevitable process in practical road paving has a great effect on the properties of polymer-modified asphalts (PMAs). In this article, the effect of short-term and long-term oxidative ageing on the rheological, physical properties and the morphology of the styrene-butadiene-styrene (SBS)- and storage-stable SBS/sulfur-modified asphalts was studied, respectively. The analysis on the rheological and physical properties of the PMAs before and after ageing showed the two major effects of ageing. On one hand, ageing prompted the degradation of polymer and increased the viscous behaviour of the modified binders, on the other, ageing changed the asphalt compositions and improved the elastic behaviour of the modified binders. The final performance of the aged binders depended on the combined effect. After ageing, the storage-stable SBS/sulfur-modified asphalts showed an obvious viscous behaviour compare with the SBS-modified asphalts and this led to an improved low-temperature creep property. The rutting resistance of the SBS-modified asphalts declined by the addition of sulfur due to the structural instability of the SBS/sulfur-modified asphalts. The rheological properties of the modified binders before and after ageing also depended strongly on the structural characteristics of SBS. The observation by using optical microscopy showed the compatibility between asphalt and SBS was improved with further ageing, especially for the storage-stable SBS/sulfur-modified asphalts.

    Hormone analysis is a precise and widely accepted tool for monitoring reproductive function and responses to stressors. Although hormones are present and can be measured in various biological matrices, non-invasive methods have gained popularity over the past 30 years as a more practical approach for assessing ovarian, testicular and, more recently, adrenocortical activity in intractable wildlife species. Non-invasive hormone monitoring also has been key to understanding biological mechanisms related to observed behaviours of captive and free-ranging animals. Despite the increasing popularity of this research field, wildlife endocrinologists have not had a specific forum for sharing and discussing their latest findings, technical developments and common challenges. To provide such a communication platform, the International Society for Wildlife Endocrinology (ISWE) was established in 2010, followed by an international meeting held on 3-4 November 2011 at the Toronto Zoo, Canada. Over several sessions, keynote speakers and participants discussed recent developments of new and innovative methods for hormone monitoring, as well as the latest advances in basic endocrinology as applied to adrenal function, reproductive physiology, animal health, ecology and evolution. Here, we introduce ISWE to the scientific community and discuss how this new society will serve as a resource for wildlife endocrinologists worldwide. PMID:22219389

    Using the method of four-wave probing of the waist of the laser beam focused into the bulk of a short active medium (L ll τc, where L is the length of the active medium, τ is the pulse duration, and c is the speed of light), we have studied the dynamics of the behaviour of a dark soliton, appearing upon a jump of the input Stokes signal phase by about π under SBS. The computer simulation has shown that when spontaneous noises with the gain increment Γ, exceeding the self-reflection threshold by 2 - 3 times, are generated, the dark soliton propagates along the interaction region for the time t ≈ T2Γth/2, where T2 is the the lifetime of acoustic phonons, and Γth = 25 - 30 is the stationary threshold gain increment.

    Introduction In today’s world of economic crisis it is not feasible for an orthodontist to replace each and every debonded bracket with a new bracket- quest for an alternative thrives Orthodontist. The concept of recycling bracket for its reuse has evolved over a period of time. Orthodontist can send the brackets to various commercial recycling companies for recycling, but it’s impractical as these are complex procedures and require time and usage of a new bracket would seem more feasible. Thereby, in-house methods have been developed. The aim of the study was to determine the SBS (Shear Bond Strength) and to compare, evaluate the efficiency of in house recycling methods with that of the SBS of new brackets. Materials and Methods Five in–house-recycling procedures-Adhesive Grinding Method, Sandblasting Method, Thermal Flaming Method, Buchman method and Acid Bath Method were used in the present study. Initial part of the study included the use of UV/Vis spectrophotometer where in the absorption level of base of new stainless steel bracket is compared with the base of a recycled bracket. The difference seen in the UV absorbance can be attributed to the presence of adhesive remnant. For each recycling procedure the difference in UV absorption is calculated. New stainless steel brackets and recycled brackets were tested for its shear bond strength with Instron testing machine. Comparisons were made between shear bond strength of new brackets with that of recycled brackets. The last part of the study involved correlating the findings of UV/Vis spectrophotometer with the shear bond strength for each recycling procedure. Results Among the recycled brackets the Sandblasting technique showed the highest shear bond strength (19.789MPa) and the least was shown by the Adhesive Grinding method (13.809MPa). Conclusion The study concludes that sand blasting can be an effective choice among the 5 in house methods of recycling methods. PMID:26501002

    Led by key opinion leaders in the field, the 25th Annual Meeting of the International Society for Biological Therapy of Cancer (iSBTc, recently renamed the Society for Immunotherapy of Cancer, SITC) provided a scientific platform for ~500 attendees to exchange cutting-edge information on basic, clinical, and translational research in cancer immunology and immunotherapy. The meeting included keynote addresses on checkpoint blockade in cancer therapy and recent advances in therapeutic vaccination against cancer induced by Human Papilloma Virus 16. Participants from 29 countries interacted through oral presentations, panel discussions, and posters on topics that included dendritic cells and cancer, targeted therapeutics and immunotherapy, innate/adaptive immune interplay in cancer, clinical trial endpoints, vaccine combinations, countering negative regulation, immune cell trafficking to tumor microenvironment, and adoptive T cell transfer. In addition to the 50 oral presentations and >180 posters on these topics, a new SITC/iSBTc initiative to create evidence-based Cancer Immunotherapy Guidelines was announced. The SITC/iSBTc Biomarkers Taskforce announced the release of recommendations on immunotherapy biomarkers and a highly successful symposium on Immuno-Oncology Biomarkers that took place on the campus of the National Institutes of Health (NIH) immediately prior to the Annual Meeting. At the Annual Meeting, the NIH took the opportunity to publicly announce the award of the U01 grant that will fund the Cancer Immunotherapy Trials Network (CITN). In summary, the Annual Meeting gathered clinicians and scientists from academia, industry, and regulatory agencies from around the globe to interact and exchange important scientific advances related to tumor immunobiology and cancer immunotherapy.

    Objective. The aim of this study was to establish guidelines for the optimization of biologic therapies for health professionals involved in the management of patients with RA, AS and PsA. Methods. Recommendations were established via consensus by a panel of experts in rheumatology and hospital pharmacy, based on analysis of available scientific evidence obtained from four systematic reviews and on the clinical experience of panellists. The Delphi method was used to evaluate these recommendations, both between panellists and among a wider group of rheumatologists. Results. Previous concepts concerning better management of RA, AS and PsA were reviewed and, more specifically, guidelines for the optimization of biologic therapies used to treat these diseases were formulated. Recommendations were made with the aim of establishing a plan for when and how to taper biologic treatment in patients with these diseases. Conclusion. The recommendations established herein aim not only to provide advice on how to improve the risk:benefit ratio and efficiency of such treatments, but also to reduce variability in daily clinical practice in the use of biologic therapies for rheumatic diseases.

    Traumatic stress can have severe consequences for both mental and physical health. Furthermore, both psychological and biological traces of trauma increase as a function of accumulating traumatic experiences. Neurobiological research may aid in limiting the impact of traumatic stress, by leading to advances in preventive and treatment interventions. To promote the possibility for clinical implementation of novel research findings, this brief review describes timely conceptual and methodological challenges and directions in neurobiological trauma research on behalf of the Task Force “Neurobiology of Traumatic Stress” of the European Society for Traumatic Stress Studies (ESTSS). The most important conceptual challenges are the heterogeneity of disorders and existence of subtypes across diagnostic categories: differential latent profiles and trajectories regarding symptom expression and neural correlates are being unraveled; however, similar latent classes’ approaches for treatment response and neurobiological data remain scarce thus far. The key to improving the efficacy of currently available preventive interventions and treatments for trauma-related disorders lies in a better understanding and characterization of individual differences in response to trauma and interventions. This could lead to personalized treatment strategies for trauma-related disorders, based on objective information indicating whether individuals are expected to benefit from them. The most important methodological challenge identified here is the need for large consortia and meta-analyses or, rather, mega-analyses on existent data as a first step. In addition, large multicenter studies, combining novel methods for repeated sampling with more advanced statistical modeling techniques, such as machine learning, should aim to translate identified disease mechanisms into molecular blood-based biomarker combinations to predict disorder vulnerability and treatment responses.

    In early 2011, a dialogue was initiated within the Board of Directors (BOD) of the American Society for Radiation Oncology (ASTRO) regarding the future of the basic sciences of the specialty, primarily focused on the current state and potential future direction of basic research within radiation oncology. After consideration of the complexity of the issues involved and the precise nature of the undertaking, in August 2011, the BOD empanelled a Cancer Biology/Radiation Biology Task Force (TF). The TF was charged with developing an accurate snapshot of the current state of basic (preclinical) research in radiation oncology from the perspective of relevance to the modern clinical practice of radiation oncology as well as the education of our trainees and attending physicians in the biological sciences. The TF was further charged with making suggestions as to critical areas of biological basic research investigation that might be most likely to maintain and build further the scientific foundation and vitality of radiation oncology as an independent and vibrant medical specialty. It was not within the scope of service of the TF to consider the quality of ongoing research efforts within the broader radiation oncology space, to presume to consider their future potential, or to discourage in any way the investigators committed to areas of interest other than those targeted. The TF charge specifically precluded consideration of research issues related to technology, physics, or clinical investigations.

    Copper thioantimonates have received enormous attention due to their potential for applications in photovoltaic devices. In this work, a new layered compound KCu2SbS3 was synthesized via a reactive flux method using thiourea as a reactive flux. The compound crystallizes in the triclinic space group P1[combining macron]. The structure features two-dimensional [Cu2SbS3](-) layers stacking along the c axis with K(+) ions intercalated between the layers. Each [Cu2SbS3](-) layer is composed of two single graphene-like layers connected via interlayer Cu-S bonds and CuSb contacts. The optical measurements indicate that the compound has a band gap of 1.7 eV. The Hall effect measurement shows that KCu2SbS3 is a p-type semiconductor with a carrier concentration of 7 × 10(16) cm(-3). First-principles calculations reveal that the direct transition occurs between Cu-3d-S-3p orbitals (VBM) to Sb-5p-S-3p orbitals (CBM). The photoelectric response properties of KCu2SbS3 under visible light irradiation were analyzed. The photocurrent is 3.7 μA cm(-2) at 10 V bias, demonstrating its potential for applications in photoelectric devices.

    Purpose: To obtain, in a survey-based study, detailed information on the faculty currently responsible for teaching radiation biology courses to radiation oncology residents in the United States and Canada. Methods and Materials: In March-December 2007 a survey questionnaire was sent to faculty having primary responsibility for teaching radiation biology to residents in 93 radiation oncology residency programs in the United States and Canada. Results: The responses to this survey document the aging of the faculty who have primary responsibility for teaching radiation biology to radiation oncology residents. The survey found a dramatic decline with time in the percentage of educators whose graduate training was in radiation biology. A significant number of the educators responsible for teaching radiation biology were not fully acquainted with the radiation sciences, either through training or practical application. In addition, many were unfamiliar with some of the organizations setting policies and requirements for resident education. Freely available tools, such as the American Society for Radiation Oncology (ASTRO) Radiation and Cancer Biology Practice Examination and Study Guides, were widely used by residents and educators. Consolidation of resident courses or use of a national radiation biology review course was viewed as unlikely by most programs. Conclusions: A high priority should be given to the development of comprehensive teaching tools to assist those individuals who have responsibility for teaching radiation biology courses but who do not have an extensive background in critical areas of radiobiology related to radiation oncology. These findings also suggest a need for new graduate programs in radiobiology.

    We present Giant Metrewave Radio Telescope HI observations of an extremely metal-deficient galaxy SBS 1129+576. SBS 1129+576 has a weighted mean oxygen abundance of 12 + log (O/H) = 7.41 +/- 0.07, or 1/18 of the solar value. Our HI observations show that the galaxy is strongly interacting with a companion (projected separation ~27 kpc) galaxy, SBS 1129+577. HI emission from a third, smaller galaxy, SDSS J113227.68+572142.3, is also present in the data cube. We study the HI morphology and kinematics of this small group at angular resolutions ranging from ~40 to 8arcsec. The low-resolution map shows a bridge of emission connecting the two larger galaxies and a large one-armed spiral distortion of the disc of SBS 1129+577. We measure HI masses of ~4.2 × 108, ~2.7 × 109 and ~2.1 × 108Msolar for SBS 1129+576, SBS 1129+577 and the gas in the bridge, respectively. Assuming that most of the bridge gas originally came from SBS 1129+576, approximately one-third of its original gas mass has been stripped off. The third smaller galaxy has an HI mass of (MHI ~ 1.1 × 107Msolar) and does not show any sign of interaction with the other two galaxies. The higher-resolution maps show that SBS 1129+577 has a central bar and a ring surrounding the bar; there is also a hint of an integral-shaped warp in SBS 1129+576. All these features are very likely to have been induced by the tidal interaction. In both SBS 1129+576 and SBS 1129+577, there is, in general, a good correspondence between regions with high HI column density and those with ongoing star formation. The two brightest HII regions in SBS 1129+576 have (inclination-corrected) gas column densities of ~1.6 × 1021 and ~1.8 × 1021 atoms cm-2, respectively. The inclination-corrected HI column density near the HII regions in SBS 1129+577 is generally above ~2.0 × 1021 atoms cm-2. These values are close to the threshold density for star formation observed in other blue compact galaxies. In contrast to SBS 1129+576 and SBS 1129

    Two organophilic bentonites, based on nitrogen-containing compounds, have been synthesised via ion exchange starting from pristine bentonite with octadecyltrimethylammonium bromide (OTAB) and with synthetic melamine-derived N2,N4-dihexadecyl-1,3,5-triazine-2,4,6-triamine (DEDMEL). The chemical and morphological characterization of the organoclays was based on XRD, TEM, Laser Granulometry, X-Ray Fluorescence and CEC capacity. Copoly(styrene-butadiene-styrene)-nanocomposites (SBS-nanocomposites) were obtained by intercalation of the SBS-copolymer into these new organoclays by melt intercalation method. XRD and TEM analysis of the organoclays and of the micro/nano-composites obtained are presented. The effect of the organoclays on the SBS-nanocomposite's flammability properties was investigated using cone calorimeter. An encouraging decrease of 20% in the peak heat released rate (PHRR) has been obtained confirming the important role of melamine's based skeleton and its derived organoclays to act as effective fire retardants and for the improvement of this important functional property in SBS copolymers.

    This paper provides a review and synthesis of current knowledge about the associations of ventilation system types in office buildings with sick building syndrome symptoms and discusses potential explanations for the associations. Relative to natural ventilation, air conditioning, with or without humidification, was consistently associated with a statistically significant increase in the prevalence of one or more SBS symptoms. Prevalences were typically higher by approximately 30% to 200% in the air conditioned buildings. In two of three assessments from a single study, symptom prevalences were also significantly higher in air conditioned buildings than in buildings with simple mechanical ventilation and no humidification. In approximately half of assessments, SBS symptom prevalences were significantly higher in buildings with simple mechanical ventilation than in buildings with natural ventilation. Insufficient information was available for conclusions about the potential increased risk of SBS symptoms with humidification. The statistically significant associations of mechanical ventilation and air conditioning with SBS symptoms are much more frequent than expected from chance and also not likely to be a consequence of confounding by several potential personal, job, or building related confounders. The reasons for the increases in symptom prevalences with mechanical ventilation and particularly with air conditioning remain unclear. Multiple deficiencies in HVAC system design, construction, operation, or maintenance, including some which cause pollutant emissions from HVAC systems, may contribute to the increases in symptom prevalences.

    2011-06-01

    The past 30 years have seen a revolution in comparative biology. Before that time, systematics was not at the forefront of the biological sciences, and few scientists considered phylogenetic relationships when investigating evolutionary questions. By contrast, systematic biology is now one of the most vigorous disciplines in biology, and the use of phylogenies not only is requisite in macroevolutionary studies but also has been applied to a wide range of topics and fields that no one could possibly have envisioned 30 years ago. My message is simple: phylogenies are fundamental to comparative biology, but they are not the be-all and end-all. Phylogenies are powerful tools for understanding the past, but like any tool, they have their limitations. In addition, phylogenies are much more informative about pattern than they are about process. The best way to fully understand the past-both pattern and process-is to integrate phylogenies with other types of historical data as well as with direct studies of evolutionary process.

  15. STUD Pulse performance comparisons between weak and strong damping limits of SBS

    2012-10-01

    The physical mechanisms that make STUD pulses (spike trains of uneven duration and delay) optimal rely, among other physical effects, on damping of the driven waves in between spikes. By varying the damping of ion acoustic waves in inhomogeneously flowing plasma regions ranging from -8 to -2 of the Mach number, we can establish to what extent STUD pulses can be effective to control SBS growth in various damping levels. By changing the duty cycle of the chain of spikes, by changing their modulation period, by adding random inter spike phase kicks and by changing the spatial hot spot profile scrambling rate, we establish bounds on how much Brillouin backscattering Rosenbluth gain can be tolerated at the average intensity and still have STUD pulses control SBS as compared to RPP or SSD or ISI. The situation is complicated by the implication of the strong coupling regime in hot spots, by pump depletion and by initial noise level dependencies which we also examine.

    The radii and radii of curvature of Stokes stimulated Brillouin scattering (SBS) beams are measured by the method of moments for smooth nearly Gaussian focused pump beams with the propagation ratio M{sup 2}{sub {sigma}p{<=}}1.2. It is shown that in the case of sufficiently deeply focused pump radiation, the propagation ratio M{sup 2}{sub {sigma}S} of Stokes beams near the threshold of the transient SBS is smaller than M{sup 2}{sub {sigma}p} and approaches it with increasing the pump pulse energy. It is also found that the radii of Stokes beams at the output from a nonlinear medium are smaller than the radii of pump beams, while the radii of wave-front curvature are close (in modulus) to the radii of wave-front curvature for pump beams.

    High molecular weight, high functionality diamino telechelic polybutadienes (TPBs) were synthesized by ring-opening metathesis polymerization (ROMP) of 1,5-cyclooctadiene (COD) in the presence of a chain transfer agent, 1,8-dicyano-4-octene, followed by lithium aluminum hydride reduction. Melt coupling of diamino TPB with anhydride-terminated polystyrene (PS-anh) resulted in the formation of styrene-butadiene-styrene (SBS) triblock copolymers; ca. 80% maximum conversion of PS-anh was achieved within 30 seconds. The results from SAXS, TEM, and rheological measurements of the coupling products confirmed the formation of SBS triblock copolymers having lamellar morphology. A fluororesent-labeled PS-anh was used to study the coupling kinetics by diluting the reactants by the addition of non-functional PS. PMID:19907636

    Many physiological and molecular processes are strongly rhythmic and profoundly influenced by sleep. The continuing effort of biological, medical, and veterinary science to understand the temporal organization of cellular, physiological, behavioral and cognitive function holds great promise for the improvement of the welfare of animals and human beings. As a result, attending veterinarians and IACUC are often charged with the responsibility of evaluating experiments on such rhythms or the effects of sleep (or its deprivation) in vertebrate animals. To produce interpretable data, animals used in such research must often be maintained in carefully controlled (often constant) conditions with minimal disruption. The lighting environment must be strictly controlled, frequent changes of cages and bedding are undesirable, and daily visual checks are often not possible. Thus deviations from the standard housing procedures specified in the Guide for the Care and Use of Laboratory Animals are often necessary. This report reviews requirements for experiments on biological rhythms and sleep and discusses how scientific considerations can be reconciled with the recommendations of the Guide. PMID:23849440

    To change the group velocity of optical signals has a lot of possible applications in telecommunications, sensing, nonlinear optics and so on. Especially the exploitation of the effect of stimulated Brillouin scattering (SBS) in optical fibers is of special interest since it just requires standard telecom equipment and low to moderate optical power. However, each delay in one single, low-gain SBS based slow-light system is accompanied by pulse broadening. This is a result of the inherent Kramers-Kronig relations between the gain, the phase-change and the accompanied group velocity. For an ideal flat gain the phase-change is non-ideal, and for an ideal phase-change the gain curve leads to a broadening. Furthermore, if the gain bandwidth is broadened in order to adapt it to the signal, the delay will be reduced. Thus, for one single low-gain slow-light system the broadening can be reduced by several methods but it cannot be zero. Here we will show how a zero-broadening SBS based slow-light system can be achieved by two different methods. The basic idea is a reshaping of the original pulse by an adapted gain in a second stage. This adaptation is achieved by the superposition of two Gaussian gain profiles or by a single saturated gain. As will be shown, these systems show an almost ideal over-all gain and phase function over the bandwidth of the pulses. Thus, SBS based slow-light with a delaybandwidth product of more than 1 bit and zero distortion is possible.

Our work has been studying the morphology of solvent-cast thin films of polystyrene-polybutadiene-polystyrene (SBS) as a function of solvent evaporation rate and post-specimen annealing. This paper describes the analysis of thin film cross-sections to distinguish between possible morphologies.

    A technique that employs two seed signals for the purpose of mitigating stimulated Brillouin scattering (SBS) effects in narrow-linewidth Yb-doped fiber amplifiers is investigated theoretically by constructing a self-consistent model that incorporates the laser gain, SBS, and four-wave mixing (FWM). The model reduces to solving a two-point boundary problem consisting of an 8x8 system of coupled nonlinear differential equations. Optimal operating conditions are determined by examining the interplay between the wavelength separation and power ratio of the two seeds. Two variants of this 'two-tone' amplification are considered. In one case the wavelength separation is precisely twice the Brillouin shift, while the other case considers a greater wavelength separation. For the former case, a two-fold increase in total output power over a broad range of seed power ratios centered about a ratio of approximately 2 is obtained, but with fairly large FWM. For the latter case, this model predicts an approximately 100% increase in output power (at SBS threshold with no signs of FWM) for a 'two-tone' amplifier with seed signals at 1064nm and 1068nm, compared to a conventional fiber amplifier with a single 1068nm seed. More significantly for this case, it is found that at a wavelength separation greater than 10nm, it is possible to appreciably enhance the power output of one of the laser frequencies. PMID:18773034

    The pioneering discovery of the heat shock response by the Italian scientist Ferruccio Ritossa reached maturity this year, 2012. It was 50 years ago that Professor Ritossa, through an extraordinary combination of serendipity, curiosity, knowledge and inspiration, published the first observation that cells could mount very strong transcriptional activity when exposed to elevated temperatures, which was coined the heat shock response. This discovery led to the identification of heat shock proteins, which impact many areas of current biology and medicine, and has created a new avenue for more exciting discoveries. In recognition of the discovery of the heat shock response, Cell Stress Society International (CSSI) awarded Professor Ritossa with the CSSI medallion in October 2010 in Dozza, Italy. This article is based on a session of the Fifth CSSI Congress held in Québec commemorating Professor Ritossa and his discovery. PMID:22252402

    Central venous access has traditionally been performed on the basis of designated anatomical landmarks. However, due to patients’ individual anatomy and vessel pathology and depending on individual operators’ skill, this landmark approach is associated with a significant failure rate and complication risk. There is substantial evidence demonstrating significant improvement in effectiveness and safety of vascular access by realtime ultrasound (US)-guidance, as compared to the anatomical landmark-guided approach. This review comments on the evidence-based recommendations on US-guided vascular access which have been published recently within the framework of Guidelines on Interventional Ultrasound (InVUS) of the European Federation of Societies for Ultrasound in Medicine and Biology (EFSUMB) from a clinical practice point of view.

    These updated guidelines are based on the first edition of the World Federation of Societies of Biological Psychiatry (WFSBP) guidelines for biological treatment of schizophrenia published in the years 2005 and 2006. For this 2015 revision, all available publications pertaining to the biological treatment of schizophrenia were reviewed systematically to allow for an evidence-based update. These guidelines provide evidence-based practice recommendations which are clinically and scientifically relevant. They are intended to be used by all physicians diagnosing and treating patients with schizophrenia. Based on the first version of these guidelines a systematic review, as well as a data extraction from national guidelines have been performed for this update. The identified literature was evaluated with respect to the strength of evidence for its efficacy and subsequently categorised into six levels of evidence (A-F) and five levels of recommendation (1-5). This third part of the updated guidelines covers the management of the following specific treatment circumstances: comorbid depression, suicidality, various comorbid substance use disorders (legal and illegal drugs), and pregnancy and lactation. These guidelines are primarily concerned with the biological treatment (including antipsychotic medication and other pharmacological treatment options) of patients with schizophrenia.

    Abstract These updated guidelines are based on a first edition of the World Federation of Societies of Biological Psychiatry (WFSBP) guidelines for biological treatment of schizophrenia published in 2006. For this 2012 revision, all available publications pertaining to the biological treatment of schizophrenia were reviewed systematically to allow for an evidence-based update. These guidelines provide evidence-based practice recommendations that are clinically and scientifically meaningful. They are intended to be used by all physicians diagnosing and treating people suffering from schizophrenia. Based on the first version of these guidelines, a systematic review of the MEDLINE/PUBMED database and the Cochrane Library, in addition to data extraction from national treatment guidelines, has been performed for this update. The identified literature was evaluated with respect to the strength of evidence for its efficacy and then categorised into six levels of evidence (A-F) and five levels of recommendation (1-5) ( Bandelow et al. 2008a ,b, World J Biol Psychiatry 9:242, see Table 1 ). This second part of the updated guidelines covers long-term treatment as well as the management of relevant side effects. These guidelines are primarily concerned with the biological treatment (including antipsychotic medication and other pharmacological treatment options) of adults suffering from schizophrenia.

    Vascular-derived hydrogen peroxide (H2O2) serves as an important signaling molecule in the cardiovascular system and contributes to vascular homeostasis. H2O2 is a second messenger, transducing the oxidative signal into biological responses through posttranslational protein modification. The balance between oxidant and antioxidant systems regulates intracellular redox status, and their imbalance causes oxidative or reductive stress, leading to cellular damage in cardiovascular systems. Excessive H2O2 deteriorates vascular functions and promotes vascular disease through multiple pathways. The RhoA/Rho-kinase pathway plays an important role in various fundamental cellular functions, including production of excessive reactive oxygen species, leading to the development of cardiovascular diseases. Rho-kinase (ROCK1 and ROCK2) belongs to the family of serine/threonine kinases and is an important downstream effector of the small GTP-binding protein RhoA. Rho-kinase plays a crucial role in the pathogenesis of vasospasm, arteriosclerosis, ischemia/reperfusion injury, hypertension, pulmonary hypertension, stroke, and heart failure. Thus, Rho-kinase inhibitors may be useful for the treatment of cardiovascular diseases in humans. In this review, we will briefly discuss the roles of vascular-derived H2O2 and review the recent progress in the translational research on the therapeutic importance of the Rho-kinase pathway in cardiovascular medicine.

    We report on the R&D effort in the design and construction of a large size Gas Electron Multiplier (GEM) for the Proton Polarimeter Back Tracker (BT) of the Super Bigbite Spectrometer (SBS) in Hall A at Thomas Jefferson National Laboratory (JLab). The SBS BT GEM trackers consist of two sets of five large GEM chambers of size 60×200 cm2. The GEM chamber is a vertical stack of four GEM modules, each with an active area of 60×50 cm2. We have built and tested several prototypes and the construction of GEM modules for SBS BT is ongoing. We describe in this paper the design and construction of the GEM module prototype as well as the preliminary results on performance from tests carried out in our detector lab and during test beam at Fermi National Laboratory (Fermilab).

    We report Fermi Large Area Telescope (LAT) observations of the radio-loud active galactic nucleus SBS 0846+513 (z = 0.5835), optically classified as a narrow-line Seyfert 1 galaxy, together with new and archival radio-to-X-ray data. The source was not active at γ-ray energies during the first two years of Fermi operation. A significant increase in activity was observed during 2010 October-2011 August. In particular, a strong γ-ray flare was observed in 2011 June reaching an isotropic γ-ray luminosity (0.1-300 GeV) of 1.0 × 1048 erg s-1, comparable to that of the brightest flat spectrum radio quasars, and showing spectral evolution in γ rays. An apparent superluminal velocity of (8.2 ± 1.5)c in the jet was inferred from 2011 to 2012 Very Long Baseline Array (VLBA) images, suggesting the presence of a highly relativistic jet. Both the power released by this object during the flaring activity and the apparent superluminal velocity are strong indications of the presence of a relativistic jet as powerful as those of blazars. In addition, variability and spectral properties in radio and γ-ray bands indicate blazar-like behaviour, suggesting that, except for some distinct optical characteristics, SBS 0846+513 could be considered as a young blazar at the low end of the blazar's black hole mass distribution.

    Slow-light effect via stimulated Brillouin scattering (SBS) in single-mode optical fibers was considered for short probe pulses of nanosecond duration relevant to Gb/s data streams. Unlike recent estimations of delay versus pump based on steady-state small-signal approximation we have used numerical solution of three-wave equations describing SBS for a realistic fiber length. Both regimes of small signal and pump depletion (gain saturation) were considered. The physical origin of Stokes pulse distortion is revealed which is related to excitation of long-living acoustic field behind the pulse and prevents effective delay control by pump power increase at cw pumping. We have shown different slope of the gain-dependent delay for different pulse durations. Spectrally broadened pumping by multiple cw components, frequency-modulated pump and pulse train were studied for short pulses which allow to obtain large delay and suppress pulse distortion. In the pump-depletion regime of pumping by pulse train, both pulse delay and distortion decrease with increasing pump, and the pulse achieves advancement.

    Presented are orbit and attitude determination results from the launch of Satellite Business Systems (SBS)-5 satellite on September 8, 1988 by Arianespace. SBS-5 is a (HS-376) spin stabilized spacecraft. The launch vehicle injected the spacecraft into a low inclination transfer orbit. Apogee motor firing (AMF) attitude was achieved with trim maneuvers. An apogee kick motor placed the spacecraft into drift orbit. Postburn, reorientation and spindown maneuvers were performed during the next 25 hours. The spacecraft was on-station 19 days later. The orbit and attitude were determined by both an extended Kalman filter and a weighted least squares batch processor. Although the orbit inclination was low and the launch was near equinox, post-AMF analysis indicated an attitude declination error of 0.034 deg., resulting in a saving of 8.5 pounds of fuel. The AMF velocity error was 0.4 percent below nominal. The post-AMF drift rate was determined with the filter only 2.5 hours after motor firing. The filter was used to monitor and retarget the reorientation to orbit normal in real time.

    We present a new method of SBS suppression in fiber amplifier system by employing simultaneously phase and intensity modulation. In this way, a GHz narrow-linewidth polarization-maintaining (PM) all-fiber pulsed laser is obtained based on a master oscillator power amplifier (MOPA) configuration. The pulsed seed is generated from a single-frequency continuous wave (CW) laser at 1064 nm by simultaneous modulation using an electro-optic intensity modulator (EOIM) and an electro-optic phase modulator (EOPM). Theoretical model is built and simulation framework has been established to estimate the SBS threshold of the pulsed amplifier system before and after modulation. In experiment, in order to suppress SBS effectively, the pulse width is set to be 4 ns and the phase modulation voltage is set to be 5 V. After amplifying by the amplifier chain, a ~3.5 ns pulsed laser with average/peak power of 293 W/3.9 kW is obtained at intensity repetition rate of 20 MHz and phase repetition rate of 100MHz, showing good agreement with simulation results. The linewidth of the output laser is ~4.5 GHz, the M(2) factor at maximal output power is measured to be ~1.1 and the slope efficiency is ~86%.This method provides some references to suppress the SBS in narrow linewidth pulsed amplifier systems.

  17. Interpretation of Single- and Multiple-Beam SBS Observations in OMEGA, Long-Scale-Length Plasma Experiments

    Recent experiments on OMEGA have studied stimulated Brillouin backscatter in preformed long-scale-length plasmas for both single and multiple interaction beams. Scattered light intensities and spectra were obtained for a variety of irradiation conditions. Ion Landau damping is estimated to be sufficiently strong in these plasmas that the locally driven approximation for the ion-sound wave response can be applied. The linear SBS gain coefficient can then obtained by integrating the coupled wave equations for the incident and scattered light throughout the underdense plasma corona. Using density, velocity, and temperature profiles obtained from the two-dimensional Eulerian hydrocode SAGE, we have calculated as a function of wavelength the SBS gain coefficients to be expected in these experiments. Comparison with the observed scattering levels and spectra allows several conclusions to be drawn regarding the SBS process in these plasmas. Most saliently, the scattering appears to be dominated by SBS occurring in hot spots, and plasma velocity profiles have a strong influence on the location and level of scattering. Generally good agreement is found between the observations and the calculations, though some discrepancies remain, particularly in the absorption levels and spectral shifts.

    Copper-based ternary chalcogenide semiconductors with zincblende-related crystal structures have recently emerged as some of the best performing p-type thermoelectric materials. Here, first-principles calculations are used to investigate the structural, elastic, and thermoelectric properties of Cu3SbSe4 and Cu3SbS4. The calculated lattice constants and atomic coordinates are in good agreement with those obtained in the previous experiments, which shows that our method is reliable. We found that the hybridization among atoms forms [SbSe4] and [CuSe4] tetrahedral structures. The spin-orbit (SO) interaction is included in the calculations for electronic structures and thermoelectric properties. It is predicted that Cu3SbSe4 and Cu3SbS4 are mechanically stable, relatively soft materials with high compressibility, and are low small-hardness ionic materials, and with more anisotropy in shear than in compressibility. The results also show that the mechanical stability of these materials is limited by the shear modulus G. Furthermore, Cu3SbSe4 can be classified as a brittle material, whereas Cu3SbS4 can be classified as a ductile material. The semiclassical Boltzmann transport theory was used to calculate the Seebeck coefficients, electrical conductivities, electronic thermal conductivities, power factors, and thermoelectric figures of merit ZeT of Cu3SbSe4 and Cu3SbS4 along two crystallographic directions, and the optimal doping concentrations were estimated on the basis of the predicted thermoelectric properties. The temperature dependences of the thermoelectric transport properties of Cu3SbSe4 and Cu3SbS4 were also estimated and compared with experimental data, with good agreement observed.

  19. Improved slow-light performance of 10 Gb/s NRZ, PSBT and DPSK signals in fiber broadband SBS.

    We have demonstrated error-free operations of slow-light via stimulated Brillouin scattering (SBS) in optical fiber for 10-Gb/s signals with different modulation formats, including non-return-to-zero (NRZ), phase-shaped binary transmission (PSBT) and differential phase-shiftkeying (DPSK). The SBS gain bandwidth is broadened by using current noise modulation of the pump laser diode. The gain shape is simply controlled by the noise density function. Super-Gaussian noise modulation of the Brillouin pump allows a flat-top and sharp-edge SBS gain spectrum, which can reduce slow-light induced distortion in case of 10-Gb/s NRZ signal. The corresponding maximal delay-time with error-free operation is 35 ps. Then we propose the PSBT format to minimize distortions resulting from SBS filtering effect and dispersion accompanied with slow light because of its high spectral efficiency and strong dispersion tolerance. The sensitivity of the 10-Gb/s PSBT signal is 5.2 dB better than the NRZ case with a same 35-ps delay. The maximal delay of 51 ps with error-free operation has been achieved. Futhermore, the DPSK format is directly demodulated through a Gaussian-shaped SBS gain, which is achieved using Gaussian-noise modulation of the Brillouin pump. The maximal error-free time delay after demodulation of a 10-Gb/s DPSK signal is as high as 81.5 ps, which is the best demonstrated result for 10-Gb/s slow-light.

    The metal-deficient (Z=Zsolar/41) blue compact dwarf galaxy SBS 0335-052 was observed with ISOCAM between 5 and 17 μm. With an L12μm/LB ratio of 2.15, the galaxy is unexpectedly bright in the mid-infrared for such a low-metallicity object. The mid-infrared spectrum shows no sign of the unidentified infrared bands, which we interpret as an effect of the destruction of their carriers by the very high UV energy density in SBS 0335-052. The spectral energy distribution (SED) is dominated by a very strong continuum, which makes the ionic lines of [S IV] and [Ne III] very weak. From 5 to 17 μm, the SED can be fitted with a graybody spectrum, modified by an extinction law similar to that observed toward the Galactic center, with an optical depth of AV~19-21 mag. Such a large optical depth implies that a large fraction (as much as ~75%) of the current star formation activity in SBS 0335-052 is hidden by dust with a mass between 3×103 and 5×105 Msolar. Silicate grains that are present as silicate extinction bands at 9.7 and 18 μm can account for the unusual shape of the MIR spectrum of SBS 0335-052. It is remarkable that such a nearly primordial environment contains as much dust as galaxies that are 10 times more metal-rich. If the hidden star formation in SBS 0335-052 is typical of young galaxies at high redshifts, then the cosmic star formation rate derived from UV/optical fluxes would be underestimated.

The regression graph of probit mortality of ticks plotted against log values of progressively increasing concentrations of amitraz revealed the slope of mortality (95% CI) as 2.36 ± 0.61 (0.38 to 4.33). The LC50 (95% CI) and LC95 (95% CI) values were recorded as 332.52 ppm (305.06–362.44) and 1646.93 ppm (1383.97–1959.84), respectively, and the resistance factor (RF) was 13.17 which indicated level II resistance status. The dose response curves for egg mass weight, reproductive index, and percentage inhibition of oviposition were also validated by AIT and the slopes (95% CI) were −7.17 ± 2.41 (−14.85 to 0.50), −0.009 ± 0.02 (−0.16 to −0.031), and 19.99 ± 4.77 (4.81 to 35.17), respectively.

    We derive the size and temperature profile of the accretion disk of the lensed quasar SBS 0909+532 by measuring the wavelength dependence (chromaticity) of the microlensing magnification produced by the stars in the lens galaxy. After correcting for extinction using the flux ratios of 14 emission lines, we observe a marked change in the B-A flux ratio with wavelength, varying from -0.67 ± 0.05 mag at (rest frame) ~1460 Å to -0.24 ± 0.07 mag at ~6560 Å. For λ >~ 7000 Å both effects, extinction and microlensing, look minimal. Simulations indicate that image B rather than A is strongly microlensed. If we model the change in disk size from 1460 Å to 6560 Å using a Gaussian source (I vprop exp(-R 2/2r 2 s )) with a disk size scaling with wavelength as rs vprop λ p , we find rs = 7+5 -3 light-days at 1460 Å and p = 0.9+0.6 -0.3 for uniform priors on rs and p, and rs = 4+3 -3 light-days and p = 1.0+0.6 -0.4 for a logarithmic prior on rs . The disk temperature profile T vprop R -1/p is consistent with thin disk theory (T vprop R -3/4), given the uncertainties. The estimates of rs are also in agreement with the size inferred from thin disk theory using the estimated black hole mass (M BH ~= 2 × 109 M sun) but not with the smaller size estimated from thin disk theory and the optical flux. We also use the flux ratios of the unmicrolensed emission lines to determine the extinction curve of the dust in the lens galaxy, finding that it is similar to that of the LMC2 Supershell.

    Purpose The goal of this survey was to obtain detailed information on the faculty currently responsible for teaching radiation biology courses to radiation oncology residents in the U.S. and Canada. Methods and Materials In March-December 2007 a survey questionnaire was sent to faculty having primary responsibility for teaching radiation biology to residents in 93 radiation oncology residency programs in the U.S. and Canada. Results The responses to this survey document the aging of the faculty who have primary responsibility for teaching radiation biology to radiation oncology residents. The survey found a dramatic decline with time in the percentage of educators whose graduate training was in radiation biology. A significant number of the educators responsible for teaching radiation biology were not fully acquainted with the radiation sciences, either through training or practical application. In addition, many were unfamiliar with some of the organizations setting policies and requirements for resident education. Freely available tools, such as the ASTRO Radiation & Cancer Biology Practice Exam used by residents and educators. Consoination and Study Guides, were widely lidation of resident courses or use of a national radiation biology review course, were viewed as unlikely to be employed by most programs. Conclusions A high priority should be given to the development of comprehensive teaching tools to assist those individuals who have responsibility for teaching radiation biology courses, but who do not have an extensive background in critical areas of radiobiology related to radiation oncology. These findings also suggest a need for new graduate programs in radiobiology. PMID:19733012

The oxygen abundances in the northwest and the southeast components of I Zw 18 are found to be the same within the errors, 7.17+/-0.03 and 7.18+/-0.03, respectively, although marginally statistically significant spatial variations of oxygen abundance might be present. In contrast, we find a statistically significant gradient of oxygen abundance in SBS 0335-052. The largest oxygen abundance, 12+logO/H=7.338+/-0.012, is found in the region 0.6" to the northeast of the brightest part of the galaxy, and it decreases toward the southwest to values of ~7.2, comparable to that in I Zw 18. The underlying stellar absorption strongly influences the observed intensities of He I emission lines in the brightest northwest component of I Zw 18, and hence this component should not be used for primordial He abundance determination. The effect of underlying stellar absorption, though present, is much smaller in the southeast component. Assuming all systematic uncertainties are negligible, the He mass fraction Y=0.243+/-0.007 derived in this component is in excellent agreement with recent measurements by Izotov & Thuan, suggesting the robustness of the technique applied in measurements of the helium abundance in low-metallicity blue compact galaxies. The high signal-to-noise ratio spectrum (>=100 in the continuum) of SBS 0335-052 allows us to measure the helium mass fraction with a precision better than 2%-5% in nine different regions along the slit. We show that, while underlying stellar absorption in SBS 0335-052 is important only for the He I 4471 Å emission line, other mechanisms such as collisional and fluorescent enhancements are influencing the intensities of all He I emission lines and should be properly taken into account.

    Browning disorder, which usually occurs post-harvest in pears subjected to long-term storage, can cause browning of the pear flesh and/or core. In 2011, investigators in China found a novel type of brown spot (designated as surface brown spot, SBS) in pre-harvest 'Dangshansuli' pears (Pyrus bretschneideri Rehd.). SBS has a large impact on the exterior quality of the pears. Interestingly, the brown coloration was only found on the peel and not the flesh or the core. In this paper, de novo transcriptome analysis of the exocarp of pears with SBS using Illumina sequencing showed that SBS up-regulated the expression of genes related to oxidative phosphorylation, phenolic compound synthesis and polyphenoloxidase (PPO), and SBS was associated with inhibition of primary and secondary metabolism genes. Ca(2+)-sensor proteins might be involved in the signal transduction that occurs during the process of SBS formation, and this signaling is likely to be regulated by H2O2, abscisic acid (ABA) and gibberellic acid (GA3). Phytohormone and mineral element analyses confirmed that GA3, ABA, H2O2 and Ca(2+) contribute to SBS formation. In addition to the seasonal characteristics, low levels of O2 and Ca(2+) in the fruit are potential causes of the browning response due to exposure to oxidative stress, oxidative-reductive imbalance and the accumulation of reactive oxygen species (ROS), which affected the membrane integrity. Disruption of the membranes allows for PPO and phenolic compounds to come into contact, and the phenolic compounds are oxidized to form the browning pigments.

In this laser source, stimulated Brillouin scattering (SBS) is the power-limiting factor, but is managed by phase modulating the seeder with a pseudo-random noise signal. Pulse energy/peak power of ~2 mJ/1.5 MW at 10 kHz repetition rate are thus obtained within ~1.55 ns pulses of peak spectral brightness >20 kW cm(-2) sr(-1) Hz(-1). PMID:23811864

    We report an all-fiberized SBS-based high repetition rate sub-nanosecond Yb fiber laser for supercontinuum generation. The high repetition rate ns laser pulses were produced from a fiber Bragg grating (FBG)-constructed fiber laser cavity consisting of a piece of double cladding Yb fiber as the gain medium and a short piece of Bi/Cr-doped fiber as a saturable absorber (SA). By optimizing the fiber length of the Bi/Cr-doped fiber and the reflectivity of the FBG, the Q-switching state of the fiber laser can be adjusted so that the energy storing condition within the fiber cavity can assure the start of stimulated Brillouin scattering (SBS) and as a result, compress the laser pulse duration. The fiber laser had an average laser power output of 1.2 W at 1064 nm with pulse repetition rate of about 80 kHz, almost four times the reported results. The pulse duration was about 1 ns with peak power of about 15 kW. After one stage of amplification, the laser power was raised to about 3 W and was used to pump a 20 m long photonic crystal fiber (PCF). Supercontiuum (SC) laser output was obtained with average power up to 1.24 W and spectrum spanning from 550 to 2200 nm.

    This study used a multiple response model (MRM) on selected items from the Views on Science-Technology-Society (VOSTS) survey to examine science-technology-society (STS) literacy among college non-science majors' taught using Problem/Case Studies Based Learning (PBL/CSBL) and traditional expository methods of instruction. An initial pilot investigation of 15 VOSTS items produced a valid and reliable scoring model which can be used to quantitatively assess student literacy on a variety of STS topics deemed important for informed civic engagement in science related social and environmental issues. The new scoring model allows for the use of parametric inferential statistics to test hypotheses about factors influencing STS literacy. The follow-up cross-institutional study comparing teaching methods employed Hierarchical Linear Modeling (HLM) to model the efficiency and equitability of instructional methods on STS literacy. A cluster analysis was also used to compare pre and post course patterns of student views on the set of positions expressed within VOSTS items. HLM analysis revealed significantly higher instructional efficiency in the PBL/CSBL study group for 4 of the 35 STS attitude indices (characterization of media vs. school science; tentativeness of scientific models; cultural influences on scientific research), and more equitable effects of traditional instruction on one attitude index (interdependence of science and technology). Cluster analysis revealed generally stable patterns of pre to post course views across study groups, but also revealed possible teaching method effects on the relationship between the views expressed within VOSTS items with respect to (1) interdependency of science and technology; (2) anti-technology; (3) socioscientific decision-making; (4) scientific/technological solutions to environmental problems; (5) usefulness of school vs. media characterizations of science; (6) social constructivist vs. objectivist views of theories; (7

    Indoor environment is associated with the sick building syndrome (SBS), but little is known about the contribution of outdoor air pollution and meteorological conditions to SBS. We studied associations between outdoor air pollution, meteorological parameters and selected indoor exposure and building characteristics at home and weekly SBS symptoms in a standardized questionnaire study among 3485 randomly selected adults in China. Outdoor factors included particulate matters with diameter <10μm (PM10), sulfur dioxide (SO2), nitrogen dioxide (NO2), outdoor temperature (T), relative air humidity (RH), and wind speed (WS) during last three months. Multiple logistic regression was applied calculating odds ratios (OR) with 95% confidence interval (95% CI). Asthma or allergic rhinitis (atopy) was associated with all types of SBS symptoms except fatigue. Indoor factors played a major role in SBS symptoms. Mold/dampness on the floor/ceiling was associated with fatigue OR=1.60 (1.11-2.30) and headache OR=1.80 (1.07-3.04). Moldy odor was associated with fatigue OR=1.59 (1.07-2.37) and dermal symptoms OR=1.91 (1.21-3.02). Window pane condensation in winter was associated with fatigue OR=1.73 (1.30-2.31) and throat symptoms OR=1.53 (1.01-2.31). Damp bed clothing was related with throat symptom OR=1.62 (1.09-2.40). Home redecoration was associated with fatigue OR=1.49 (1.07-2.06). Frequent window opening was associated with less nose symptoms OR=0.54 (0.36-0.82) and mechanical ventilation in the bathroom reduced dermal symptoms OR=0.66 (0.44-0.99).

    We present X-ray observations of the close binary nucleus of the planetary nebula SBS 1150+599A obtained with the XMM-Newton satellite. Only one component of the binary can be observed in optical-UV. New X-ray observations show that the previously invisible component is a very hot compact star. This finding allows us to deduce rough values for the basic parameters of the binary. With a high probability the total mass of the system exceeds Chandrasekhar limit and makes the SBS1150+599A one of the best candidate for a supernova type Ia progenitor.

    Programs in animal science are particularly well suited for graduate education because students can receive comprehensive training in the laboratory as well as with the whole animal. Furthermore, graduate students in animal science have the opportunity to understand how their research relates to a real world problem. Graduate students need to take ownership of their education by identifying training goals, choosing a mentor who will help them achieve their goals, and becoming engaged in research as soon as possible. In my own graduate program, I emphasize concepts more than techniques and I believe that graduate course work should focus on the basic areas of science that underlie reproductive biology (e.g., endocrinology, biochemistry, physiology, immunology, and statistics). Based on the increase in technology available for scientific investigation and the diversity of expertise required to address important research problems, graduate students need to learn the importance of establishing productive collaborations and begin building a scientific network. Preparation for graduate school frequently begins early with a curiosity and passion for understanding how biology works. Undergraduate courses can facilitate scientific thinking by providing opportunities in lectures and laboratories for students to transition from passive learners to thinking of themselves as animal scientists. There is a profound difference between individuals who view themselves as practitioners of a discipline and those who are simply trying to complete a course requirement. Teachers of undergraduate courses should incorporate experiential learning exercises into their lectures and laboratories to provide undergraduate students the opportunity to function as animal scientists and to embrace their scientific education. Graduate training has been the most enjoyable aspect of my career and it has been a joy to witness the achievements of students following completion of their degree!

    All-solid-state sodium batteries, using solid electrolyte and abundant sodium resources, show great promise for safe, low-cost, and large-scale energy storage applications. The exploration of novel solid electrolytes is critical for the room temperature operation of all-solid-state Na batteries. An ideal solid electrolyte must have high ionic conductivity, hold outstanding chemical and electrochemical stability, and employ low-cost synthetic methods. Achieving the combination of these properties is a grand challenge for the synthesis of sulfide-based solid electrolytes. Design of the solid electrolyte Na3 SbS4 is described, realizing excellent air stability and an economic synthesis based on hard and soft acid and base (HSAB) theory. This new solid electrolyte also exhibits a remarkably high ionic conductivity of 1 mS cm(-1) at 25 °C and ideal compatibility with a metallic sodium anode. PMID:27246874

    Mr. Brown feels the world needs a land ethic to guide resource planning and an ecological theology to serve as custodian over the thinning topsoil, spreading desert, and growing population. In a sustainable society, durability and recycling replace obsolescence as the economy's organizing principle, and virgin materials are seen not as a primary source of material but as a supplement to the existing stock. The key to national security is sustainability. If the biological underpinnings of the global economic system cannot be secured, and if new energy sources and systems are not in place as the oil wells go dry, then economic disruptions and breakdowns are inevitable. In effect, the traditional military concept of national security grows less adequate in the face of growing non-military threats. 154 notes and references, 6 figures, 41 tables.

    This retrospective review on discoveries of the roles of oxidative stress in brain of subjects with Alzheimer disease (AD) and animal models thereof as well as brain from animal models of chemotherapy induced cognitive impairment (CICI) results from the author receiving the 2013 Discovery Award from the Society for Free Radical Biology and Medicine. The paper reviews our laboratory's discovery of: protein oxidation and lipid peroxidation in AD brain regions rich in amyloid β-peptide (Aβ) but not in Aβ-poor cerebellum; redox proteomics as a means to identify oxidatively modified brain proteins in AD and its earlier forms that are consistent with the pathology, biochemistry, and clinical presentation of these disorders; how Aβ in in vivo, ex vivo, and in vitro studies can lead to oxidative modification of key proteins that also are oxidatively modified in AD brain; the role of the single methionine residue of Aβ(1-42) in these processes; and some of the potential mechanisms in the pathogenesis and progression of AD. CICI affects a significant fraction of the 14 million American cancer survivors, and due to diminished cognitive function, reduced quality of life of the persons with CICI (called “chemobrain” by patients) often results. A proposed mechanism for CICI employed the prototypical ROS-generating and non-blood brain barrier (BBB)-penetrating chemotherapeutic agent doxorubicin (Dox, also called adriamycin, ADR). Because of the quinone moiety within the structure of Dox, this agent undergoes redox cycling to produce superoxide free radical peripherally. This, in turn, leads to oxidative modification of the key plasma protein, Apolipoprotein A1 (ApoA1). Oxidized ApoA1 leads to elevated peripheral TNFα, a pro-inflammatory cytokine that crosses the BBB to induce oxidative stress in brain parenchyma that affects negatively brain mitochondria. This subsequently leads to apoptotic cell death resulting in CICI. This review outlines aspects of CICI consistent

    By comparing the impact of established laser smoothing techniques like Random Phase Plates (RPP) and Smoothing by Spectral Dispersion (SSD) to the concept of "Spike Trains of Uneven Duration and Delay" (STUD pulses) on the amplification of parametric instabilities in laser-produced plasmas, we show with the help of numerical simulations, that STUD pulses can drastically reduce instability growth by orders of magnitude. The simulation results, obtained with the code Harmony in a nonuniformly flowing mm-size plasma for the Stimulated Brillouin Scattering (SBS) instability, show that the efficiency of the STUD pulse technique is due to the fact that successive re-amplification in space and time of parametrically excited plasma waves inside laser hot spots is minimized. An overall mean fluctuation level of ion acoustic waves at low amplitude is established because of the frequent change of the speckle pattern in successive spikes. This level stays orders of magnitude below the levels of ion acoustic waves excited in hot spots of RPP and SSD laser beams.

    All-solid-state sodium batteries, using abundant sodium resources and solid electrolyte, hold much promise for safe, low cost, large-scale energy storage. To realize the practical applications of all solid Na-ion batteries at ambient temperature, the solid electrolytes are required to have high ionic conductivity, chemical stability, and ideally, easy preparation. Ceramic electrolytes show higher ionic conductivity than polymers, but they often require extremely stringent synthesis conditions, either high sintering temperature above 1000 C or long-time, low-energy ball milling. Herein, we report a new synthesis route for Na3SbS4, a novel Na superionic conductor that needs much lower processing temperature below 200 Cmore » and easy operation. This new solid electrolyte exhibits a remarkable ionic conductivity of 1.05 mS cm-1 at 25 °C and is chemically stable under ambient atmosphere. In conclusion, this synthesis process provides unique insight into the current state-of-the-art solid electrolyte preparation and opens new possibilities for the design of similar materials.« less

    We present a comprehensive experimental study of the technique of Longitudinal Mode Filling (LMF) applied to the reduction of Stimulated Brillouin Scattering (SBS), in Ytterbium Doped Fibre Amplifiers (YDFA) at the wavelength of 1064 nm. Pulse durations and Mode Field Diameters (MFD) lie in the ranges of 10 - 100 ns and 10 - 35 μm, respectively. Input pulse-shaping is implemented by means of direct current modulation in multimode Laser-Diode seeds. This evidences a number of interests in the development of robust and low cost Master Oscillator Power Amplifiers (MOPA). Highly energetic, but properly shaped, nanosecond pulses may be produced this way without any need of additional electro-optical means for in-line phase and amplitude modulation. Seeds consist of Distributed Feed- Back (DFB) and Fibre Bragg Gratings (FBG) with different fibre lengths. We demonstrate the benefit of LMF with properly controlled mode spacing, in combination with chirp effects due to fast current transients in the semiconductors, in order to deal with SBS thresholds in the range of a few to some hundred μJ. The variations of the SBS threshold are discussed versus the number of longitudinal modes, the operating conditions of the selected seed and pulse-shaping conditions.

We identified 425 patients with a prior malignancy from 18 000 RA patients in the study. Of these, 101 patients developed a new malignancy. The rates of incident malignancy were 33.3 events/1000 person-years (py) in the TNFi cohort, 24.7 events/1000 py in the RTX cohort and 53.8 events/1000 py in the sDMARD cohort. The age- and gender-adjusted hazard ratio was 0.55 (95% CI: 0.35, 0.86) for the TNFi cohort and 0.43 (95% CI: 0.10, 1.80) for the RTX cohort in comparison with the sDMARDs cohort. The 17.0% of patients in the sDMARDs cohort had a recurrence of the same cancer in comparison with the 12.8% and the 4.3% in the TNFi and RTX cohorts, respectively. Conclusions. Although numbers are still low, it seems that patients with RA and prior malignancy selected to receive either a TNFi or RTX in the UK do not have an increased risk of future incident malignancy.

    There are fewer longitudinal studies from China on symptoms as described for the sick building syndrome (SBS). Here, we performed a two-year prospective study and investigated associations between environmental parameters such as room temperature, relative air humidity (RH), carbon dioxide (CO2), nitrogen dioxide (NO2), sulphur dioxide (SO2), ozone (O3), particulate matter (PM10), and health outcomes including prevalence, incidence and remission of SBS symptoms in junior high schools in Taiyuan, China. Totally 2134 pupils participated at baseline, and 1325 stayed in the same classrooms during the study period (2010–2012). The prevalence of mucosal symptoms, general symptoms and symptoms improved when away from school (school-related symptoms) was 22.7%, 20.4% and 39.2%, respectively, at baseline, and the prevalence increased during follow-up (P<0.001). At baseline, both indoor and outdoor SO2 were found positively associated with prevalence of school-related symptoms. Indoor O3 was shown to be positively associated with prevalence of skin symptoms. At follow-up, indoor PM10 was found to be positively associated with new onset of skin, mucosal and general symptoms. CO2 and RH were positively associated with new onset of mucosal, general and school-related symptoms. Outdoor SO2 was positively associated with new onset of skin symptoms, while outdoor NO2 was positively associated with new onset of skin, general and mucosal symptoms. Outdoor PM10 was found to be positively associated with new onset of skin, general and mucosal symptoms as well as school-related symptoms. In conclusion, symptoms as described for SBS were commonly found in school children in Taiyuan City, China, and increased during the two-year follow-up period. Environmental pollution, including PM10, SO2 and NO2, could increase the prevalence and incidence of SBS and decrease the remission rate. Moreover, parental asthma and allergy (heredity) and pollen or pet allergy (atopy) can be risk factors

  17. Morphological development in solvent-cast polystyrene(PS)-polybutadiene(PB)-polystyrene (SBS) triblock copolymer thin films

    NASA Astrophysics Data System (ADS)

    Kim, Ginam

    The morphological characteristics of block copolymers have been under intensive research, because of the rich polymer-physics questions they raise and because of the need for better understanding required by adhesive, compatibilizer, and template applications. In this research, the morphological transformations in solvent-cast polystyrene (PS)/polybutadiene (PB)/polystyrene (SBS)(30 wt% PS, Mw = 112,000) triblock copolymer thin films have been studied by transmission electron microscopy (TEM) as a function of solvent evaporation rate and post-evaporation annealing. Evaporation at: (i) ˜200 nl/sec produces a microphase-separated microstructure with no long-range order; (ii) ˜5 nl/sec generates hexagonally packed PS cylinders in a PB matrix with the cylinder axis perpendicular to the film plane; (iii) ˜1.5 nl/sec leads to a duplex microstructure of PS cylinders with domains of either vertical or in-plane cylinders; (iv) ˜0.2 nl/sec produces a fully in-plane cylinder microstructure. Post-evaporation annealing converts the duplex morphology into one with only in-plane PS cylinders. The equilibrium morphology of in-plane cylinders with PB-rich surface layers is generated when films are given relatively long exposure to high solvent concentration or elevated temperature. However, alternate and metastable morphologies are generated including ones with two-phase surface structure under kinetically constrained conditions. Cross-sectional TEM indicates that the surface microstructures vary with evaporation and annealing treatment. These results are interpreted in terms of the kinetics and thermodynamics of microphase separation.

  18. TIME DELAY AND ACCRETION DISK SIZE MEASUREMENTS IN THE LENSED QUASAR SBS 0909+532 FROM MULTIWAVELENGTH MICROLENSING ANALYSIS

    2013-09-01

    We present three complete seasons and two half-seasons of Sloan Digital Sky Survey (SDSS) r-band photometry of the gravitationally lensed quasar SBS 0909+532 from the U.S. Naval Observatory, as well as two seasons each of SDSS g-band and r-band monitoring from the Liverpool Robotic Telescope. Using Monte Carlo simulations to simultaneously measure the system's time delay and model the r-band microlensing variability, we confirm and significantly refine the precision of the system's time delay to {Delta}t{sub AB} = 50{sub -4}{sup +2} days, where the stated uncertainties represent the bounds of the formal 1{sigma} confidence interval. There may be a conflict between the time delay measurement and a lens consisting of a single galaxy. While models based on the Hubble Space Telescope astrometry and a relatively compact stellar distribution can reproduce the observed delay, the models have somewhat less dark matter than we would typically expect. We also carry out a joint analysis of the microlensing variability in the r and g bands to constrain the size of the quasar's continuum source at these wavelengths, obtaining log {l_brace}(r{sub s,r}/cm)[cos i/0.5]{sup 1/2}{r_brace} = 15.3 {+-} 0.3 and log {l_brace}(r{sub s,g}/cm)[cos i/0.5]{sup 1/2}{r_brace} = 14.8 {+-} 0.9, respectively. Our current results do not formally constrain the temperature profile of the accretion disk but are consistent with the expectations of standard thin disk theory.

  20. Epigenetic Determinism in Science and Society

    PubMed Central

    Waggoner, Miranda R.; Uller, Tobias

    2015-01-01

    The epigenetic “revolution” in science cuts across many disciplines, and it is now one of the fastest growing research areas in biology. Increasingly, claims are made that epigenetics research represents a move away from the genetic determinism that has been prominent both in biological research and in understandings of the impact of biology on society. We discuss to what extent an epigenetic framework actually supports these claims. We show that, in contrast to the received view, epigenetics research is often couched in language as deterministic as genetics research in both science and the popular press. We engage the rapidly emerging conversation about the impact of epigenetics on public discourse and scientific practice, and we contend that the notion of epigenetic determinism – or the belief that epigenetic mechanisms determine the expression of human traits and behaviors – matters for understandings of the influence of biology and society on population health.

    There are few studies on sick building syndrome (SBS) including clinical measurements for atopy and fractional exhaled nitric oxide (FeNO). Our aim was to study associations between SBS symptoms, selected personal factors, office characteristics and indoor office exposures among office workers from a university in Malaysia. Health data were collected by a questionnaire (n=695), skin prick test (SPT) (n=463) and FeNO test (n=460). Office settled dust was vacuumed and analyzed for endotoxin, (1,3)-β-glucan and house dust mites (HDM) allergens group 1 namely Dermatophagoides pteronyssinus (Der p 1) and Dermatophagoides farinae (Der f 1). Office indoor temperature, relative air humidity (RH), carbon monoxide (CO) and carbon dioxide (CO2) were measured by a direct reading instrument. Associations were studied by two-levels multiple logistic regression with mutual adjustment and stratified analysis. The prevalence of weekly dermal, mucosal and general symptoms was 11.9%, 16.0% and 23.0% respectively. A combination of SPT positivity (allergy to HDM or cat) and high FeNO level (≥25 ppb) was associated with dermal (p=0.002), mucosal (p<0.001) and general symptoms (p=0.05). Der f1 level in dust was associated with dermal (p<0.001), mucosal (p<0.001) and general (p=0.02) symptoms. Among those with allergy to D. farinae, associations were found between Der f 1 levels in dust and dermal (p=0.003), mucosal (p=0.001) and general symptoms (p=0.007). Office-related symptoms were associated with Der f 1 levels in dust (p=0.02), low relative air humidity (p=0.04) and high office temperature (p=0.05). In conclusion, a combination of allergy to cat or HDM and high FeNO is a risk factor for SBS symptoms. Der f 1 allergen in dust can be a risk factor for SBS in the office environment, particularly among those sensitized to Der f 1 allergen. PMID:26225741

    Background: Preclinical studies have demonstrated that macroporous silk fibroin protein scaffolds are capable of promoting physiologically durable supportive tissue, which favors application of these engineered tissues for clinical implantation. The safety and effectiveness of a long-lasting, transitory, 510(k)-cleared purified silk fibroin biologic scaffold (SBS) are investigated for soft-tissue support and repair of the abdominal wall. Methods: We conducted a multicenter retrospective review of all consecutive patients who underwent abdominal wall soft-tissue reinforcement with an SBS device between 2011 and 2013. Indications, comorbid conditions, surgical technique, complications, and outcomes were evaluated. Results: We reviewed the records of 172 consecutive patients who received an SBS for soft-tissue support. Of those, 77 patients underwent abdominal wall fascial repair, with a mean follow-up of 18.4 ± 7.5 months. Procedures using an SBS included reinforcement of an abdominal-based flap donor site (31.2%), ventral hernia repair (53.2%), and abdominoplasty (15.6%). The overall complication rate was 6.5%, consisting of 2 wound dehiscences, 1 with device exposure, 1 seroma, 1 infection with explantation, and a perioperative bulge requiring reoperation. There were no reports of hernia. Conclusions: Postoperative complication rates after 18 months were low, and most surgical complications were managed nonoperatively on an outpatient basis without mesh removal. To our knowledge, this is the only series to report on a long-lasting, transitory SBS for abdominal wall repair and reinforcement. Procedure-specific outcome studies are warranted to delineate optimal patient selection and define potential device characteristic advantages. PMID:25506529

    The Indian Vacuum Society (IVS) was established in 1970. It has over 800 members including many from Industry and R & D Institutions spread throughout India. The society has an active chapter at Kolkata. The society was formed with the main aim to promote, encourage and develop the growth of Vacuum Science, Techniques and Applications in India. In order to achieve this aim it has conducted a number of short term courses at graduate and technician levels on vacuum science and technology on topics ranging from low vacuum to ultrahigh vacuum So far it has conducted 39 such courses at different parts of the country and imparted training to more than 1200 persons in the field. Some of these courses were in-plant training courses conducted on the premises of the establishment and designed to take care of the special needs of the establishment. IVS also regularly conducts national and international seminars and symposia on vacuum science and technology with special emphasis on some theme related to applications of vacuum. A large number of delegates from all over India take part in the deliberations of such seminars and symposia and present their work. IVS also arranges technical visits to different industries and research institutes. The society also helped in the UNESCO sponsored post-graduate level courses in vacuum science, technology and applications conducted by Mumbai University. The society has also designed a certificate and diploma course for graduate level students studying vacuum science and technology and has submitted a syllabus to the academic council of the University of Mumbai for their approval, we hope that some colleges affiliated to the university will start this course from the coming academic year. IVS extended its support in standardizing many of the vacuum instruments and played a vital role in helping to set up a Regional Testing Centre along with BARC. As part of the development of vacuum education, the society arranges the participation of

    2012-12-01

    The presence of a relativistic jet in some radio-loud Narrow-Line Seyfert 1s (NLSy1) galaxies, first suggested by their variable radio emission and the flat radio spectra, is now confirmed by the Fermi-LAT detection of five NLSy1s in γ rays. In particular, a strong γ-ray flare from SBS 0846+513 was observed in 2011 June by Fermi-LAT reaching a γ-ray luminosity (0.1-300 GeV) of ~1048 erg s-1, comparable to that of bright flat spectrum radio quasars. Apparent superluminal velocity in the jet was inferred from 2011-2012 VLBA images, suggesting the presence of a highly relativistic jet. Both the power released by this object during the flaring activity and the apparent superluminal velocity are strong indicators of the presence of a relativistic jet as powerful as those in blazars. In addition, variability and spectral properties in radio and γ-ray bands indicate a blazar-like behaviour, suggesting that, except for some distinct optical characteristics, SBS 0846+513 could be considered as a young blazar at the low end of the blazar's black hole mass distribution.

    The reliability of the Spanish version of the Social Behaviour Schedule (SBS) was tested in a vocational setting on a sample of 64 subjects with learning disabilities. Test-retest assessment showed a good percentage of agreement (80%) and adequate kappa values for most SBS items. The overall percentage of agreement of inter-rater reliability was 85% and kappa values were moderate to nearly perfect for 52% of items. Inter-informant analyses produced poorer results, with an average agreement of 43% and inadequate kappa values on 42% of items. The intraclass correlation coefficient (ICC) was 0.64 for test-retest, 0.76 for inter-rater assessment and 0.94 for inter-informant assessment. The Spearman correlation coefficient was adequate on the test-retest and inter-rater analyses, but not on inter-informant analysis. This low inter-informant agreement could be attributed to environmental factors which alter the reliability of reports from different informants in community settings with high levels of normalization. In such environments, an interview with a key informant may not suffice, and both a careful review of the clinical record and a direct interview with subjects may enhance the reliability of the information attained.

  11. Connecting the solubility and CCN activation of complex organic aerosols: A theoretical study using the Solubility Basis Set (SBS)

    2015-04-01

    INTRODUCTION Organic aerosol particles often consist of thousands of compounds with different properties. One of these properties is solubility, which affects the hygroscopic growth and CCN activation of the organic particles. Here we investigate the CCN activation behavior of complex organic aerosols accounting for the distribution of solubilities present in these mixtures. METHODS We considered a monodisperse population of spherical aerosol particles consisting of an internal mixture of organic compounds. When exposed to water vapor, these particles were assumed to grow reaching a thermodynamic equilibrium between the water vapor and the particle phase. The composition of the organic and aqueous phases was determined on one hand by the equilibrium between the aqueous phase and water vapor, and on the other hand by the equilibrium of the aqueous phase with the organic insoluble phase. We modelled the mixtures with the help of a solubility basis set (SBS, analogous to the volatility basis set VBS, Donahue et al. 2006, 2011, 2012), describing the mixture with n surrogate compounds with varying solubilities. We varied the range and shape of the solubility distribution, and the number of components n in the distribution, we also assumed two different kinds of interactions between the organic compounds in the insoluble phase 1) ideal mixture, where organics limit each other's dissolution; 2) unity activity, where organics behave as pure compounds and do not influence each other's dissolution. Critical supersaturations and the dissolution behavior at the point of CCN activation were calculated utilizing the Köhler theory for all organic mixtures (denoted here as the "full model"). The full model predictions were compared with the three simplified models: 1) assuming complete dissolution of all compounds; 2) treating the organic mixture solubility with the hygroscopicity parameter κ and 3) assuming a fixed soluble fraction ɛ for each mixture.

Today in the United States we should give particular attention to three immediate problems. We should reinvigorate our national economic health and international competitiveness, particularly by reducing our unprecedented budget deficits and reforming our tax system. We must strengthen our scientific and engineering vitality, particularly in graduate engineering education and in secondary school instruction in science and mathematics. And we should work with our allies in the free industrialized world to keep our international open society as open as possible, encouraging a flow of people and information and ideas across national boundaries while instituting sensible and efficient safeguards against leakage of critical military technology to the Soviet Union.

    As the decade of mega-tsunamis has unfolded with new data, the science of tsunami has advanced at an unprecedented pace. Our responsibility to society should guide the use of these new scientific discoveries to better prepare society for the next tsunami. This presentation will focus on the impacts of the 2004 and 2011 tsunamis and new societal expectations accompanying enhanced funding for tsunami research. A list of scientific products, including tsunami hazard maps, tsunami energy scale, real-time tsunami flooding estimates, and real-time current velocities in harbors will be presented to illustrate society's need for relevant, easy to understand tsunami information.

    Leach, Edmund

    1975-01-01

    Sir Edmund Leach argues that doctors in the modern world, fortified by the traditional concept that the life of the sick person must at all costs be preserved, are to some extent guilty of the false antitheses current today between youth and age. Moreover youth means health, age illness and senility. Until this imbalance is corrected society will be in danger of `a kind of civil war between the generations'. Society must be taught again that mortality cannot be avoided or conquered by medical science, and at the same time that `health' is not enshrined in the young alone. PMID:1177271

Under the changing circumstances of advanced informationalization added values of information has become much higher. It causes computer crime, hacker, computer virus to come to the surface. In addition it can be said that infringement of intellectual property and privacy are threats brought by advanced information. Against these threats legal, institutional and insurance measures have been progressed, and newly security industry has been established. However, they are not adequate individually or totally. The future vision should be clarified, and countermeasures according to the visions have to be considered.

    A huge flow of quantitative social, demographic and behavioral data is becoming available that traces the activities and interactions of individuals, social patterns, transportation infrastructures and travel fluxes. This has caused, together with innovative computational techniques and methods for modeling social actions in hybrid (natural and artificial) societies, a qualitative change in the ways we model socio-technical systems. For the first time, society can be studied in a comprehensive fashion that addresses social and behavioral complexity. In other words we are in the position to envision the development of large data and computational cyber infrastructure defining an exploratory of society that provides quantitative anticipatory, explanatory and scenario analysis capabilities ranging from emerging infectious disease to conflict and crime surges. The goal of the exploratory of society is to provide the basic infrastructure embedding the framework of tools and knowledge needed for the design of forecast/anticipatory/crisis management approaches to socio technical systems, supporting future decision making procedures by accelerating the scientific cycle that goes from data generation to predictions.

  20. Shrinking societies favor procreation.

    PubMed

    Kent, M M

    1999-12-01

    Low birth rates and unprecedented improvements in life expectancy had brought a shrinking society to a rapidly expanding retirement-age population. In 1999, people aged 65 and older make up 15% or more of the populations in 19 countries. Furthermore, 14 country populations are already experiencing natural decrease, and a lot more will start to decline early in the 21st century. Due to this predicament, concerned countries have created policies that may encourage more childbearing by easing the opportunity costs of raising children. Among the policies are: 1) paid maternity and paternity leaves until a child is 2-3 years; 2) free child care; 3) tax breaks for large families; 4) family housing allowance; 5) cash paid to parents for raising a child. Governments of the shrinking societies believed that these policies could influence fertility because it affects the socioeconomic setting in which childbearing decisions are made. This paper also discusses Hungary, Japan, and Sweden fertility policies. PMID:12295635

    Apart from the journals they produce, scientific societies play an important role in communicating scientific findings and norms to the broader society. The American Association for the Advancement of Science (AAAS) includes among its goals to promote and defend the integrity of science and its use; provide a voice for science on societal issues; promote the responsible use of science in public policy; and increase public engagement with science and technology. AAAS websites and programs, including Communicating Science (www.aaas.org/communicatingscience), Working with Congress (http://www.aaas.org/spp/cstc/wwc/book.htm) and ScienceCareers.org (http://sciencecareers.sciencemag.org), provide tools for scientists to become more directly engaged in effectively communicating their findings and involved in the policy process. Education programs work to build the next generation of scientists and a science-literate public. To bridge the current communication gap between scientists, the public and policymakers, AAAS, like other scientific societies, maintains policy and outreach programs with limited budgets and staff. AAAS works to engage policymakers and provide scientific underpinning to key issues through congressional briefings, meetings, policy briefs, and media outreach. AAAS responds to challenges to accepted scientific findings and processes through op-eds, letters to government officials, resolutions, and Board statements. Some of these initiatives occur on a local level in partnership with local civic leaders, whose endorsement makes them more powerful. On a national scale, they assure that the voice of science is included in the debate. The changing media landscape presents opportunities and challenges for future AAAS endeavors.

We know more now than we have ever known about human development and the base of acquired knowledge is increasing exponentially. In this paper we share some thoughts about where we are in the science of human development, how we got there, what may be going wrong and what may be going right. Finally, we offer some thoughts about where we go from here to assure that in the future we achieve the best developmental science possible. PMID:25642155

    In modern society, metrology is a hidden infrastructure, that affects most human activities. Several domains in which measurements, and therefore metrology, play a crucial role are presented and illustrated with examples: manufacturing industries, navigation, telecommunications, medicine, environment, and scientific research. The BIPM and the national metrology institutes are at the top of traceability chains, which guarantee that all measurements are performed in conformity with the International System of Units (SI) and are therefore comparable. Finally, some indications of the economic benefits of metrology are given. To cite this article: T.J. Quinn, J. Kovalevsky, C. R. Physique 5 (2004).

    This article discusses the U.S. and European national strategies and policies for information society. Coping with the declining competitiveness in high-tech products and Japanese technological advantages both have been trying hard to strengthen technology base and to deregulate the telecommunications services markets. The U.S. approach in 1980's, unlike its liberalist principle, has been characterized by technological protectlonism and defense-oriented policies. European Communities' approach has been more comprehensive and systematic, investing heavily telecommunication infrastructure, deregulating domestic market, and promoting cooperation of member countries. However, both of these approaches have, so far, been unable to achieve a considerable success.

    Despite improvements in modern cardiovascular therapy, the morbidity and mortality of ischaemic heart disease (IHD) and heart failure (HF) remain significant in Europe and worldwide. Patients with IHD may benefit from therapies that would accelerate natural processes of postnatal collateral vessel formation and/or muscle regeneration. Here, we discuss the use of cells in the context of heart repair, and the most relevant results and current limitations from clinical trials using cell-based therapies to treat IHD and HF. We identify and discuss promising potential new therapeutic strategies that include ex vivo cell-mediated gene therapy, the use of biomaterials and cell-free therapies aimed at increasing the success rates of therapy for IHD and HF. The overall aim of this Position Paper of the ESC Working Group Cellular Biology of the Heart is to provide recommendations on how to improve the therapeutic application of cell-based therapies for cardiac regeneration and repair.

    Surface layer (S-layer) proteins self-assemble into two-dimensional crystalline lattices that cover the cell wall of all archaea and many bacteria. We have generated assembly-negative protein variants of high solubility that will facilitate high-resolution structure determination. Assembly-negative versions of the S-layer protein SbsB from Geobacillus stearothermophilus PV72/p2 were obtained using an insertion mutagenesis screen. The haemagglutinin epitope tag was inserted at 23 amino acid positions known to be located on the monomer protein surface from a previous cysteine accessibility screen. Limited proteolysis, circular dichroism, and fluorescence were used to probe whether the epitope insertion affected the secondary and tertiary structures of the monomer, while electron microscopy and size-exclusion chromatography were employed to examine proteins' ability to self-assemble. The screen not only identified assembly-compromised mutants with native fold but also yielded correctly folded, self-assembling mutants suitable for displaying epitopes for biomedical and biophysical applications, as well as cryo-electron microscopy imaging. Our study marks an important step in the analysis of the S-layer structure. In addition, the approach of concerted insertion and cysteine mutagenesis can likely be applied for other supramolecular assemblies. PMID:19836402

    "Nothing in science has any value to society if it is not communicated." So goes the 1952 quote from Anne Roe, the noted twentieth century American psychologist and writer. She went on to say that "scientists are beginning to learn their social obligations", and now over 60 years later there is certainly evidence to support her assertions. As scientists, by communicating our research to the general public we not only better inform the tax payer where their money is being spent, but are also able to help put into context the topical environmental challenges and issues that society faces, as well as inspiring a whole new generation of future scientists. This process of communication is very much a two-way street; by presenting our work to people outside of our usual spheres of contemporaries, we expose ourselves to alternative thoughts and insights that can inspire us, as scientists, to take another look at our research from angles that we had never before considered. This work presents the results and experiences from a number of public engagement and outreach activities across the UK, in which geoscientists engaged and interacted with members of the general public. These include the design and implementation of Raspberry Pi based outreach activities for several hundred high school students; the process of running a successful podcast (http://thebarometer.podbean.com); hosting and participating in science events for thousands of members of the general public (e.g. http://www.manchestersciencefestival.com and http://sse.royalsociety.org/2013); and creating a citizen science activity that involved primary school children from across the UK. In communicating their research it is imperative that scientists interact with their audience in an effective and engaging manner, whether in an international conference, a classroom, or indeed down the pub. This work also presents a discussion of how these skills can be developed at an early stage in the careers of a research

    Murray, T J

    1995-11-15

    As health care changes under the pressures of restraint and constraint our vision of the future of medical education should be based on the medical school's responsibility to the community. The medical school is "an academy in the community": as an academy, it fosters the highest standards in education and research; as an institution in the community, it seeks to improve public health and alleviate suffering. The author argues that to better achieve these goals medical schools need to become more responsible and responsive to the population they serve. Medical schools have been slow to accept fully the social contract by which, in return for their service to society, they enjoy special rights and benefits. This contract requires that medical educators listen to the public, talk honestly and constructively with government representatives and assess the needs and expectations of the community.

This is followed by a summary review of the proposed solutions identified in other papers in this special issue of The Behavior Analyst, most of which relate to either better marketing of either the behavior analytic process or the results achieved as a consequence. One paper proposes a more broad conception of behavior analysis. This paper endorses the solutions identified in previous papers and then goes on to propose an even more broad conception of behavior analysis and makes the point that behavior analysis is unlikely to flourish unless behavior analysts understand a good deal more about the cultural and other contextual features of the environments in which they work.

    Embryos have different meanings for different people and in different contexts. Seen under the microscope, the biological embryo starts out as one cell and then becomes a bunch of cells. Gradually these divide and differentiate to make up the embryo, which in humans becomes a fetus at eight weeks, and then eventually a baby. At least, that happens in those cases that carry through normally and successfully. Yet a popular public perception imagines the embryo as already a little person in the very earliest stages of development, as if it were predictably to become an adult. In actuality, cells can combine, pull apart, and recombine in a variety of ways and still produce embryos, whereas most embryos never develop into adults at all. Biological embryos and popular imaginations of embryos diverge. This paper looks at some of the historical reasons for and social implications of that divergence.

    Woese, Carl R.

    2004-01-01

    Biology today is at a crossroads. The molecular paradigm, which so successfully guided the discipline throughout most of the 20th century, is no longer a reliable guide. Its vision of biology now realized, the molecular paradigm has run its course. Biology, therefore, has a choice to make, between the comfortable path of continuing to follow molecular biology's lead or the more invigorating one of seeking a new and inspiring vision of the living world, one that addresses the major problems in biology that 20th century biology, molecular biology, could not handle and, so, avoided. The former course, though highly productive, is certain to turn biology into an engineering discipline. The latter holds the promise of making biology an even more fundamental science, one that, along with physics, probes and defines the nature of reality. This is a choice between a biology that solely does society's bidding and a biology that is society's teacher. PMID:15187180

    Although positive reciprocity (reciprocal altruism) has been a focus of interest in evolutionary biology, negative reciprocity (retaliatory infliction of fitness reduction) has been largely ignored. In social animals, retaliatory aggression is common, individuals often punish other group members that infringe their interests, and punishment can cause subordinates to desist from behaviour likely to reduce the fitness of dominant animals. Punishing strategies are used to establish and maintain dominance relationships, to discourage parasites and cheats, to discipline offspring or prospective sexual partners and to maintain cooperative behaviour.

    In October 2005, as the United States still was reeling from Hurricane Katrina in August and as the alphabet was too short to contain all of that year's named Atlantic tropical storms (Hurricane Wilma was forming near Jamaica), a timely workshop in Bermuda focused on climate extremes and society (see Eos, 87(3), 25, 17 January 2006). This edited volume, which corresponds roughly to the presentations given at that workshop, offers a fascinating look at the critically important intersection of acute climate stress and human vulnerabilities. A changing climate affects humans and other living things not through the variable that most robustly demonstrates the role of rising greenhouse gases—globally averaged temperature—but through local changes, especially changes in extremes. The first part of this book, “Defining and modeling the nature of weather and climate extremes,” focuses on natural science. The second part, “Impacts of weather and climate extremes,” focuses on societal impacts and responses, emphasizing an insurance industry perspective because a primary sponsor of the workshop was the Risk Prediction Initiative, whose aim is to “support scientific research on topics of interest to its sponsors” (p. 320).

  19. Centrosymmetry vs noncentrosymmetry in La2Ga0.33SbS5 and Ce4GaSbS9 based on the interesting size effects of lanthanides: Syntheses, crystal structures, and optical properties

    NASA Astrophysics Data System (ADS)

    Zhao, Hua-Jun

    2016-05-01

    Two new quaternary sulfides La2Ga0.33SbS5 and Ce4GaSbS9 have been prepared from stoichiometric elements at 1223 K in an evacuated silica tube. Interestingly, La2Ga0.33SbS5 crystallizes in the centrosymmetric structure, while Ce4GaSbS9 crystallizes in the noncentrosymmetric structure, which show obvious size effects of lanthanides on the crystal structures of these two compounds. Ce4GaSbS9 belongs to RE4GaSbS9 (RE=Pr, Nd, Sm, Gd-Ho) structure type with a=13.8834(9) Å, b=14.3004(11) Å, c=14.4102(13) Å, V=2861.0(4) Å3. The structure features infinite chains of [Ga2Sb2S1110-]∞ propagating along a direction separated by Ce3+ cations and S2- anions. La2Ga0.33SbS5 adopts the family of La4FeSb2S10-related structure with a=7.5193(6) Å, c=13.4126(17) Å, V=758.35(13) Å3. Its structure is built up from the alternate stacking of La/Sb/S and La/Ga/S 2D building blocks. The La/Sb/S slabs consist of teeter-totter chains of Sb1S4 seesaws, which are connected via sharing the apexes of μ4-S1. Moreover, La1 is positionally disordered with Sb1 and stabilized in a bicapped trigonal prismatic coordination sphere. Between these La/Sb/S slabs, La2S8 square antiprisms are connected via edge-sharing into 2D building blocks, creating tetrahedral sites partially occupied by the Ga1 atoms. UV/Vis diffuse reflectance spectroscopy study shows that the optical gap of La2Ga0.33SbS5 is about 1.76 eV.

  8. Abortion in a just society.

    PubMed

    Hunt, M E

    1993-01-01

    A female Catholic theologian imagines a just society that does not judge women who decide to undergo an abortion. The Church, practitioners, and the courts must trust that women do make person-enhancing choices about the quality of life. In the last 15 years most progress in securing a woman's right to abortion has been limited to white, well-educated, and middle or upper middle class women. A just society would consider reproductive options a human right. Abortion providers are examples of a move to a just society; they are committed to women's well-being. There are some facts that make one pessimistic about achieving abortion in a just society. The US Supreme Court plans to review important decisions establishing abortion as a civil right. Further, some men insist on suing women who want to make their own reproductive decisions--an anti-choice tactic to wear away women's right to reproductive choice. Bombings of abortion clinics and harassment campaigns by anti-choice groups are common. These behaviors strain pro-choice proponents emotionally, psychically, and spiritually. Their tactics often lead to theologians practicing self-censorship because they fear backlash. Abortion providers also do this. Further, the reaction to AIDS is that sex is bad. Anti-abortion groups use AIDS to further their campaigns, claiming that AIDS is a punishment for sex. Strategies working towards abortion in a just society should be education and persuasion of policymakers and citizens about women's right to choose, since they are the ones most affected by abortion. Moreover, only women can secure their rights to abortion. In a just society, every health maintenance organization, insurance company, and group practice would consider abortion a normal service. A just society provides for the survival needs of the most marginalized.

  10. Multilevel selection and social evolution of insect societies

    NASA Astrophysics Data System (ADS)

    Korb, Judith; Heinze, Jürgen

    How sterile, altruistic worker castes have evolved in social insects and how they are maintained have long been central topics in evolutionary biology. With the advance of kin selection theory, insect societies, in particular those of haplodiploid bees, ants, and wasps, have become highly suitable model systems for investigating the details of social evolution and recently also how within-group conflicts are resolved. Because insect societies typically do not consist of clones, conflicts among nestmates arise, for example about the partitioning of reproduction and the allocation of resources towards male and female sexuals. Variation in relatedness among group members therefore appears to have a profound influence on the social structure of groups. However, insect societies appear to be remarkably robust against such variation: division of labor and task allocation are often organized in more or less the same way in societies with high as in those with very low nestmate relatedness. To explain the discrepancy between predictions from kin structure and empirical data, it was suggested that constraints-such as the lack of power or information-prevent individuals from pursuing their own selfish interests. Applying a multilevel selection approach shows that these constraints are in fact group-level adaptation preventing or resolving intracolonial conflict. The mechanisms of conflict resolution in insect societies are similar to those at other levels in the biological hierarchy (e.g., in the genome or multicellular organisms): alignment of interests, fair lottery, and social control. Insect societies can thus be regarded as a level of selection with novelties that provide benefits beyond the scope of a solitary life. Therefore, relatedness is less important for the maintenance of insect societies, although it played a fundamental role in their evolution.

    2002-08-10

    CARING STAFF DISTRESS: Is a theme regularly discussed among those who care for patients. The current approach is in favor of the psychological interpretation of this distress. This approach is obviously pertinent, but could be widened to a more sociological vision: is the demand that society places on medicine excessive? THE SEARCH FOR AUTONOMY: The demand of the society emerges in a social universe that privileges the autonomy of the individual. Medicine serves this research for autonomy. Techniques, instrumentalization of the body, and the search for mastery engender the collective utopia of the perfect body; medicine has become a new faith, keeper of potential redemption measures. THE MEDIATOR FUNCTION OF CARING STAFF: Part of the caring staff distress is generated by the encounter between the utopia of health and the reality of suffering patients. In the present context of our society, one of the caring staff's missions is to act as mediator between the patient and the experience of the disease, the patient and the representation that he/she has of his/her body and health, and society and the expectations society projects on medicine.

  12. Molecular evolutionary analyses of insect societies

    2011-01-01

    The social insects live in extraordinarily complex and cohesive societies, where many individuals sacrifice their personal reproduction to become helpers in the colony. Identifying adaptive molecular changes involved in eusocial evolution in insects is important for understanding the mechanisms underlying transitions from solitary to social living, as well as the maintenance and elaboration of social life. Here, we review recent advances made in this area of research in several insect groups: the ants, bees, wasps, and termites. Drawing from whole-genome comparisons, candidate gene approaches, and a genome-scale comparative analysis of protein-coding sequence, we highlight novel insights gained for five major biological processes: chemical signaling, brain development and function, immunity, reproduction, and metabolism and nutrition. Lastly, we make comparisons across these diverse approaches and social insect lineages and discuss potential common themes of eusocial evolution, as well as challenges and prospects for future research in the field.

  14. Scientific citizenship in a democratic society.

    PubMed

    Arnason, Vilhjálmur

    2013-11-01

    Using the example of the sociological analysis of biological citizenship and literacy, it is argued that a merely descriptive analysis of these phenomena does not capture their distinctive normative features. While such a description realistically demonstrates how citizens respond to and are shaped by biotechnology and biomedical discourse, it provides no critique of the forces moulding the citizen-consumer. Ideas of active citizenship fuel the search for forms of public engagement in the spirit of deliberative democracy. While these attempts are guided by an important vision of policy making in democratic society, they are beset with several practical difficulties. It is argued that the discussion of deliberative practices has focused too much on direct participation of citizens in various dialogical events and its impact on policy and decision making. This approach ignores other important aspects of deliberative democratic theory, emphasizing public accountability and trustworthiness of democratic institutions.

  15. Psychiatry and society: a sociobiologic synthesis.

    PubMed

    Eisenberg, L

    1977-04-21

    The very legitimacy of psychiatry as a medical speciality has been challenged by social-labelling theory: the hypothesis that psychiatric disorders are artifacts that result from assigning diagnostic labels to minor deviations in behavior and thus generating expectations that condemn the person to a career of patienthood. Close examination of the evidence demonstrats that, through improper care care retard recovery, psychiatric illness exists before the name assigned to it, and independently of theories about its genesis. In this respect, psychiatric illness does not differ from other medical problems. All human diseases reflect the outcome of an interaction between biology and social organization, with culture in a mediating role. Whatever the proximate cause of disease -- viral, genetic, metabolic or neoplastic -- the way in which society is organized affects prevalence, cause and outcome. The physician's task is to intervene to minimize distress and preserve adaptive capacity, when cure is not possible. PMID:846511

  16. Lattice defects as Lotka-Volterra societies

    SciTech Connect

    Yost, F.G.

    1995-07-01

    Since the early part of this century the Lotka-Volterra or predator-prey equations have been known to simulate the stability, instability, and persistent oscillations observed in many biological and ecological societies. These equations have been modified in many ways and have been used to model phenomena as varied as childhood epidemics, enzyme reactions, and conventional warfare. In the work to be described, similarities are drawn between various lattice defects and Lotka-Volterra (LV) societies. Indeed, grain boundaries are known to ``consume`` dislocations, inclusions ``infect`` grain boundaries, and dislocations ``annihilate`` dislocations. Several specific cases of lattice defect interaction kinetics models are drawn from the materials science literature to make these comparisons. Each model will be interpreted as if it were a description of a biological system. Various approaches to the modification of this class of interaction kinetics will be presented and discussed. The earliest example is the Damask-Dienes treatment of vacancy-divacancy annealing kinetics. This historical model will be modified to include the effects of an intermediate species and the results will be compared with the original model. The second example to be examined is the Clark-Alden model for deformation-enhanced grain growth. Dislocation kinetics will be added to this model and results will be discussed considering the original model. The third example to be presented is the Ananthakrishna-Sahoo model of the Portevin-Le Chatelier effect that was offered in 1985 as an extension of the classical Cottrell atmosphere explanation. Their treatment will be modified by inclusion of random interference from a pesky but peripheral species and by allowing a rate constant to be a function of time.

    The social controversy created in regard to the use and experiments with transgenic seeds and organisms serves as an example to illustrate the effects and consequences that can lead to antiscientific attitudes, which have gained great force in contemporary society. It has been suggested that the same functional relationship, from which the Enlightenment, science, and liberalism were born, is currently being applied in the opposite direction, so that the current antiscientific attitudes, along with the support they receive from post-modern thought, can end up undermining the bases of an open and democratic society. The consequences of this phenomenon are already manifested by the approval of certain regulations that lack scientific basis.

  15. Participation of women in neurochemistry societies.

    PubMed

    Lees, Marjorie B

    2002-11-01

    Women have made important scientific contributions to the field of neurochemistry, and they have also been leaders in neurochemical societies throughout the world. Here I discuss women's involvement and leadership in six neurochemistry societies: American Society for Neurochemistry, Argentine Society for Neurochemistry, International Society for Neurochemistry, European Society for Neurochemistry, Japanese Society for Neurochemistry, and Asian-Pacific Society for Neurochemistry. The number of women who have been active in these societies and the level of their activity vary considerably. Neurochemical societies in the Western hemisphere, i.e., the American and the Argentine Society for Neurochemistry, have much greater numbers of women who have held office, been on council, or engaged in other leadership activities than in the rest of the world. The limited participation of women in the Japanese Neurochemistry Society relates to Japanese cultural views and was not unexpected. However, the relatively few women leaders in the International Society for Neurochemistry was a surprise. The European Society had a somewhat better record of female participation than did the International Society. The reasons for these differences are partly cultural, but factors related to when each society was formed, how it is organized, and how elections are structured undoubtedly play a role. Further analysis of these observations would be of interest from a sociological and a women's studies point of view.

This society resulted in the year 2006 after several attempts from the fusion of two established German societies, which were dealing with topics around the spine, der "German Society for Spine Research" founded in the year 1958 and the "German Society for Spine Surgery" founded in the year 1987. This fusion was the beginning of a success story, as from this time on the annual membership increased so much that the DWG became the largest spine society in Europe and one of all spine societies worldwide.

  20. Cooperation and the fate of microbial societies.

    Microorganisms have been cooperating with each other for billions of years: by sharing resources, communicating with each other, and joining together to form biofilms and other large structures. These cooperative behaviors benefit the colony as a whole; however, they may be costly to the individuals performing them. This raises the question of how such cooperation can arise from natural selection. Mathematical modeling is one important avenue for exploring this question. Evolutionary experiments are another, providing us with an opportunity to see evolutionary dynamics in action and allowing us to test predictions arising from mathematical models. A new study in this issue of PLOS Biology investigates the evolution of a cooperative resource-sharing behavior in yeast. Examining the competition between cooperating and "cheating" strains of yeast, the authors find that, depending on the initial mix of strains, this yeast society either evolves toward a stable coexistence or collapses for lack of cooperation. Using a simple mathematical model, they show how these dynamics arise from eco-evolutionary feedback, where changes in the frequencies of strains are coupled with changes in population size. This study and others illustrate the combined power of modeling and experiment to elucidate the origins of cooperation and other fundamental questions in evolutionary biology. PMID:23637573

    The Society was founded in 1962, at an international meeting organized at the Biomedical Institute rue des Saints-Pères, in Paris in the Department of Biochemistry headed at that time by Pr. Max F. Jayle, and published in the "Exposés Annuels de Biochimie Médicale" in 1963. At its beginnings a "Club", with a limited number of participants, it expanded rapidly into a Society, renamed recently "French Society of the Biology of Extracellular Matrix", with approximately 200 members working on a variety of subjects. Only six of these teams could present an oral report at the meeting of the Biological Society on January 18, 2012, celebrating this anniversary at the Curie Institute. A few more could send written contributions for this special issue of "Biologie Aujourd'hui". In this short introduction we shall recall some important stages of the developing connective tissue science. Besides such classical subjects, as the macromolecular components of connective tissue matrix, this discipline incorporated progressively receptors, integrins and other molecules, that mediate cell-matrix interactions.

  2. Leadership in an Egalitarian Society

    2014-01-01

    Leadership is instrumental to resolution of collective action dilemmas, particularly in large, heterogeneous groups. Less is known about the characteristics or effectiveness of leadership in small-scale, homogeneous, and relatively egalitarian societies, in which humans have spent most of our existence. Among Tsimane’ forager-horticulturalists of Bolivia, we (1) assess traits of elected leaders under experimental and naturalistic conditions and (2) test whether leaders impact collective action outcomes. We find that elected leaders are physically strong and have more kin and other exchange partners. Their ranks on physical dominance, kin support, and trustworthiness predict how well their groups perform, but only where group members have a history of collaborative interaction. Leaders do not take more of the spoils. We discuss why physically strong leaders can be compatible with egalitarianism, and we suggest that leaders in egalitarian societies may be more motivated by maintaining an altruistic reputation than by short-term rewards of collective action.

    There is growing concern that future flood losses and fatalities might increase significantly in many regions of the world because of rapid urbanization in deltas and floodplains, in addition to sea level rise and climate change. To better anticipate long-term trajectories of future flood risk, there is a need to treat floodplains and deltas as fully coupled human-physical systems. Here we propose a novel approach to explore the long-term behavior emerging from the mutual interactions and feedbacks between physical and social systems. The implementation of our modeling framework shows that green societies, which cope with flooding by resettling out of floodplains, are more resilient to increasing flood frequency than technological societies, which deal with flooding by building levees. Also, we show that when coupled dynamics are accounted for, flood-poor periods could (paradoxically) be more dangerous than flood-rich periods.

  4. Conflict resolution in insect societies.

    Ratnieks, Francis L W; Foster, Kevin R; Wenseleers, Tom

    2006-01-01

    Although best known for cooperation, insect societies also manifest many potential conflicts among individuals. These conflicts involve both direct reproduction by individuals and manipulation of the reproduction of colony members. Here we review five major areas of reproductive conflict in insect societies: (a) sex allocation, (b) queen rearing, (c) male rearing, (d) queen-worker caste fate, and (e) breeding conflicts among totipotent adults. For each area we discuss the basis for conflict (potential conflict), whether conflict is expressed (actual conflict), whose interests prevail (conflict outcome), and the factors that reduce colony-level costs of conflict (conflict resolution), such as factors that cause workers to work rather than to lay eggs. Reproductive conflicts are widespread, sometimes having dramatic effects on the colony. However, three key factors (kinship, coercion, and constraint) typically combine to limit the effects of reproductive conflict and often lead to complete resolution.

  5. Risk, society and system failure.

    PubMed

    Scalliet, Pierre

    2006-09-01

    Modern societies are risk societies. Together with the formidable development of complex technologies (chemical industry, energy production, mass transportation, etc), new hazards have emerged. Sharing danger is the hallmark of modernity, as large industrial accidents can now have countrywide, or even, worldwide consequences. The Chernobyl explosion for example, has smeared large European surfaces with radioactive materials, across borders and nations, without any regard for who was responsible and who was the victim. Complex technologies should therefore be managed with great foresightness, particularly focusing on preventive management. A sound understanding of the (minor) role of human errors of operators and the (major) role of process design is a pre-requisite for appropriate management. This also applies to the complex business of radiotherapy, as the same organisational principles apply than in the heavy industry: restrict the role of operators, expect their mistakes, design in a mistake-proof way, accept the burden of preventive maintenances, supervise maintenance carefully and, above all, invest in safety.

    Since early 1997, when the creation of Dolly the sheep by somatic cell nuclear transfer was announced in Nature, numerous government reports, essays, articles and books have considered the ethical problems and policy issues surrounding human reproductive cloning. In this article, I consider what response a modern liberal society should give to the prospect of human cloning, if it became safe and practical. Some opponents of human cloning have argued that permitting it would place us on a slippery slope to a repugnant future society, comparable to that portrayed in Aldous Huxley's novel, Brave New World. I conclude that, leaving aside concerns about safety, none of the psychological or social considerations discussed in this article provides an adequate policy justification for invoking the state's coercive powers to prevent human cloning.

    Three ethics exist as a condition of possibility of any possible ethics, following a material and biological foundation. This content argument (not logical-formal) supposes a refutation of the naturalistic fallacy that the analytical philosophy attributes to Hume, in three areas of the ethical human experience: body, society and nature. These are: the ethics of the species [J. Habermas], the ethics of liberation [E. Dussel] and the ethics of the responsibility [H. Jonas]. This material argument is a philosophical foundation to considering for three types of applied ethics: medical bioethics, development ethics and environmental ethics.

    1997-01-01

    The organization and evolution of insect societies has amazed natural historians since Aristotle. Charles Darwin considered social insects to be a major difficulty for his theory of evolution by natural selection because they demonstrate a rich diversity of adaptation among sterile workers leading to a complex division of labour, something that should not occur if variation in individual reproductive success is the grist for the mill of natural selection. This article shows how division of labour can self-organize from groups of cohabiting individuals without the necessity of a past history of natural selection for co-operative behaviour. It then explores how more complex social systems may evolve.

    2010-08-01

    Biological weapons are weapons of mass destruction that use pathogens (bacteria, viruses) or the toxins produced by them to target living organisms or to contaminate non-living substances. In the past, biological warfare has been repeatedly used. Anthrax, plague and smallpox are regarded as the most dangerous biological weapons by various institutions. Nowadays it seems quite unlikely that biological warfare will be employed in any military campaigns. However, the possibility remains that biological weapons may be used in acts of bioterrorism. In addition all diseases caused by biological weapons may also occur naturally or as a result of a laboratory accident. Risk assessment with regard to biological danger often proves to be difficult. In this context, an early identification of a potentially dangerous situation through experts is essential to limit the degree of damage.

  4. Social penalty promotes cooperation in a cooperative society.

    2015-01-01

    Why cooperation is well developed in human society is an unsolved question in biological and human sciences. Vast studies in game theory have revealed that in non-cooperative games selfish behavior generally dominates over cooperation and cooperation can be evolved only under very limited conditions. These studies ask the origin of cooperation; whether cooperation can evolve in a group of selfish individuals. In this paper, instead of asking the origin of cooperation, we consider the enhancement of cooperation in a small already cooperative society. We ask whether cooperative behavior is further promoted in a small cooperative society in which social penalty is devised. We analyze hawk-dove game and prisoner's dilemma introducing social penalty. We then expand it for non-cooperative games in general. The results indicate that cooperation is universally favored if penalty is further imposed. We discuss the current result in terms of the moral, laws, rules and regulations in a society, e.g., criminology and traffic violation. PMID:26238521

    2006-06-23

    Recent behavioral experiments aimed at understanding the evolutionary foundations of human cooperation have suggested that a willingness to engage in costly punishment, even in one-shot situations, may be part of human psychology and a key element in understanding our sociality. However, because most experiments have been confined to students in industrialized societies, generalizations of these insights to the species have necessarily been tentative. Here, experimental results from 15 diverse populations show that (i) all populations demonstrate some willingness to administer costly punishment as unequal behavior increases, (ii) the magnitude of this punishment varies substantially across populations, and (iii) costly punishment positively covaries with altruistic behavior across populations. These findings are consistent with models of the gene-culture coevolution of human altruism and further sharpen what any theory of human cooperation needs to explain.

    The biology revolution over the last 50 years has been driven by the ascendancy of molecular biology. This was enthusiastically embraced by most biologists because it took us into increasingly familiar territory. It took mysterious processes, such as the replication of genetic material and assigned them parts that could be readily understood by the human mind. When we think of ''molecular machines'' as being the underlying basis of life, we are using a paradigm derived from everyday experience. However, the price that we paid was a relentless drive towards reductionism and the attendant balkanization of biology. Now along comes ''systems biology'' that promises us a solution to the problem of ''knowing more and more about less and less''. Unlike molecular biology, systems biology appears to be taking us into unfamiliar intellectual territory, such as statistics, mathematics and computer modeling. Not surprisingly, systems biology has met with widespread skepticism and resistance. Why do we need systems biology anyway and how does this new area of research promise to change the face of biology in the next couple of decades?

  12. Is synthetic biology mechanical biology?

    PubMed

    Holm, Sune

    2015-12-01

    A widespread and influential characterization of synthetic biology emphasizes that synthetic biology is the application of engineering principles to living systems. Furthermore, there is a strong tendency to express the engineering approach to organisms in terms of what seems to be an ontological claim: organisms are machines. In the paper I investigate the ontological and heuristic significance of the machine analogy in synthetic biology. I argue that the use of the machine analogy and the aim of producing rationally designed organisms does not necessarily imply a commitment to mechanical biology. The ideal of applying engineering principles to biology is best understood as expressing recognition of the machine-unlikeness of natural organisms and the limits of human cognition. The paper suggests an interpretation of the identification of organisms with machines in synthetic biology according to which it expresses a strategy for representing, understanding, and constructing living systems that are more machine-like than natural organisms.

  17. Using emergent order to shape a space society

    NASA Technical Reports Server (NTRS)

    Graps, Amara L.

    1993-01-01

    A fast-growing movement in the scientific community is reshaping the way that we view the world around us. The short-hand name for this movement is 'chaos'. Chaos is a science of the global, nonlinear nature of systems. The center of this set of ideas is that simple, deterministic systems can breed complexity. Systems as complex as the human body, ecology, the mind or a human society. While it is true that simple laws can breed complexity, the other side is that complex systems can breed order. It is the latter that I will focus on in this paper. In the past, nonlinear was nearly synonymous with unsolvable because no general analytic solutions exist. Mathematically, an essential difference exists between linear and nonlinear systems. For linear systems, you just break up the complicated system into many simple pieces and patch together the separated solutions for each piece to form a solution to the full problem. In contrast, solutions to a nonlinear system cannot be added to form a new solution. The system must be treated in its full complexity. While it is true that no general analytical approach exists for reducing a complex system such as a society, it can be modeled. The technical involves a mathematical construct called phase space. In this space stable structures can appear which I use as analogies for the stable structures that appear in a complex system such as an ecology, the mind or a society. The common denominator in all of these systems is that they rely on a process called feedback loops. Feedback loops link the microscopic (individual) parts to the macroscopic (global) parts. The key, then, in shaping a space society, is in effectively using feedback loops. This paper will illustrate how one can model a space society by using methods that chaoticists have developed over the last hundred years. And I will show that common threads exist in the modeling of biological, economical, philosophical, and sociological systems.

    2004-10-01

    The ocean is arguably the largest habitat on the planet, and it houses an astounding array of life, from microbes to whales. As a testament to this diversity and its importance, the discipline of biological oceanography spans studies of all levels of biological organization, from that of single genes, to organisms, to their population dynamics. Biological oceanography also includes studies on how organisms interact with, and contribute to, essential global processes. Students of biological oceanography are often as comfortable looking at satellite images as they are electron micrographs. This diversity of perspective begins the textbook Biological Oceanography, with cover graphics including a Coastal Zone Color Scanner image representing chlorophyll concentration, an electron micrograph of a dinoflagellate, and a photograph of a copepod. These images instantly capture the reader's attention and illustrate some of the different scales on which budding oceanographers are required to think. Having taught a core graduate course in biological oceanography for many years, Charlie Miller has used his lecture notes as the genesis for this book. The text covers the subject of biological oceanography in a manner that is targeted to introductory graduate students, but it would also be appropriate for advanced undergraduates.

    The increased use of social networking is changing the way that scientific societies interact with their members and others. The American Association for the Advancement of Science (AAAS) uses a variety of online networks to engage its members and the broader scientific community. AAAS members and non-members can interact with AAAS staff and each other on AAAS sites on Facebook, YouTube, and Twitter, as well as blogs and forums on the AAAS website (www.aaas.org). These tools allow scientists to more readily become engaged in policy by providing information on current science policy topics as well as methods of involvement. For example, members and the public can comment on policy-relevant stories from Science magazine’s ScienceInsider blog, download a weekly policy podcast, receive a weekly email update of policy issues affecting the scientific community, or watch a congressional hearing from their computer. AAAS resource websites and outreach programs, including Communicating Science (www.aaas.org/communicatingscience), Working with Congress (www.aaas.org/spp/cstc/) and Science Careers (http://sciencecareers.sciencemag.org) also provide tools for scientists to become more personally engaged in communicating their findings and involved in the policy process.

  1. Mobilising Data in a Knowledge Society

    We address how the open data movement is fostering change in institutions, in data, and in social participation in the mobilisation of knowledge society. The idea of a knowledge society has been raised over the last two decades but the transition to such as society has not been realised. Up to the present time, discussion about a knowledge society have largely focused on a knowledge economy and information society rather than a mobilisation to a knowledge society. These debates have, however, taken place before the rise of open data and big data and the development of an open data movement. We consider the role of the open data movement in fostering transformation to a knowledge society. The characteristics of the open data movement that include the strong conviction of the value of open data for society, the attention to the institutional aspects of making data open in an inclusive way, the practical focus on the technological infrastructure are key in mobilising a knowledge society. At the heart of any mobilisation is an emerging open data ecosystem and new ways of producing and using data - whether 'born digital' data, digitised data or big data - and how that data, when made openly available, can be used in a knowledgeable way by societal actors.

  2. Children's rights, parents' prerogatives, and society's obligations.

    Westman, J C

    1999-01-01

    The thesis of this article is that parents do not need specifically defined rights. They have prerogatives that flow from the right of their children to nurturing and protective parenting. The idea of individual rights springs from the vulnerability of human beings in the face of stronger forces. The most vulnerable individuals are children. For this reason, human rights ought to begin with the rights of children in our society and in their families. This article discusses individual rights, society's expectations of parents and children, parental prerogatives and liabilities, parenthood as a developmental stage in the life cycle, parenthood as the foundation of society, and society's obligation to support parenthood.

    The use of biological agents as controlled weapons of war is practical although uncertain. Three types of agents are feasible, including pathogenic organisms and biological pests, toxins, and synthetic hormones regulating plant growth. These agents may be chosen for selective effects varying from prolonged incipient illness to death of plants, man and domestic animals. For specific preventive and control measures required to combat these situations, there must be careful and detailed planning. The nucleus of such a program is available within the existing framework of public health activities. Additional research and expansion of established activities in time of attack are necessary parts of biological warfare defense. PMID:13059641

    This meeting, held in the Limerick Institute of Technology, on Thursday 1 June 2006, was organised by the Munster Group of the Institute of Physics in Ireland to commemorate the life and work of John Desmond Bernal. Bernal, was born in Nenagh in 1901. Alan Mackay, who worked with Bernal at Birkbeck College coins the word 'Polytropic' to describe Bernal. He was active and hugely influential in a wide range of areas such as science, politics and society, and was instrumental in the creation of whole new areas of intellectual endeavour such as the 'science of science', molecular biology, and operations research. Andrew Brown's analogy for Bernal's mind is that 'it was like a diamond—beautifully structured, multifaceted and dazzling to behold'. In relation to Bernal, Helena Sheehan states that: 'His legacy is complex. All the more so because he was marxist in philosophy, communist in politics, polyamorous in sexuality.'. Like religion, these are areas that conventional scientists tend to shy away from or at the very least consign to very separate and often neglected 'compartments'. According to Sheehan, 'Bernal came to marxism seriously and intelligently. He found in its philosophical framework a structure in which he could live, think, create, pursue science, act politically and develop further. It opened him radically to the world, rather than closing him down or constricting him, as critics imply.'. And his contributions to science and to society are significant and enduring. Just two areas of 'his science' were addressed in some detail at this meeting. Martin Caffrey treats the area of structural biology in the context of modern developments but focusing on Bernal's role in its evolution. John Finney gives an account of Bernal's 'two bouts of activity' on the structure of water and as Bernal's last PhD student he gives unique insights on how Bernal worked and why he 'did science'. Bernal writes in response to a well wisher on his 70th birthday: 'I am sure that

    From its official founding on November 18, 1936 to the present day, the Soil Science Society of America (SSSA) has developed a rich and diverse history. SSSA began with 190 members grouped into six sections: 1) physics, 2) chemistry, 3) microbiology, 4) fertility, 5) morphology, and 6) technology. Today SSSA has over 6,000 members who can choose from any of 11 divisions, S1 Soil Physics, S2 Soil Chemistry, S3 Soil Biology and Biochemistry, S4 Soil Fertility and Plant Nutrition, S5 Pedology, S6 Soil and Water Management and Conservation, S7 Forest, Range, and Wildland Soils, S8 Nutrient Management and Soil and Plant Analysis, S9 Soil Mineralogy, S10 Wetland Soils, and S11 Soils and Environmental Quality to represent their primary area(s) of interest. The Society has also gone from being largely agriculturally focused to an eclectic mix of individuals with interests in agriculture, the environment, earth sciences, human interactions, and other diverse areas. At its founding, SSSA sponsored one publication, the Soil Science Society of America Proceedings. Today, SSSA sponsors its descendent, the Soil Science Society of America Journal, as well as Vadose Zone Journal, the Journal of Environmental Quality, Soil Survey Horizons, and the Journal of Natural Resources and Life Science Education. In short, SSSA's history has been one of continued growth over the last 75 years. The future holds many challenges for SSSA and the field of soil science. There are increasing calls to meet with groups other than or in addition to the American Society of Agronomy and the Crop Science Society of America, groups like the Geological Society of America and the Ecological Society of America. Members in SSSA now work in university departments, government agencies, and businesses representing the fields of biology, geology, geography, and archeology, among others, in addition to the traditional agricultural sector. How SSSA handles this diversification of the field and its membership will

    Leadership is an active area of research in both the biological and social sciences. This review provides a transdisciplinary synthesis of biological and social-science views of leadership from an evolutionary perspective, and examines patterns of leadership in a set of small-scale human and non-human mammalian societies. We review empirical and theoretical work on leadership in four domains: movement, food acquisition, within-group conflict mediation, and between-group interactions. We categorize patterns of variation in leadership in five dimensions: distribution (across individuals), emergence (achieved versus inherited), power, relative payoff to leadership, and generality (across domains). We find that human leadership exhibits commonalities with and differences from the broader mammalian pattern, raising interesting theoretical and empirical issues. PMID:26552515

  13. GLOBAL DISASTERS: Geodynamics and Society

    NASA Astrophysics Data System (ADS)

    Vikulina, Marina; Vikulin, Alexander; Semenets, Nikolai

    2013-04-01

    The problem of reducing the damage caused by geodynamic and social disasters is a high priority and urgent task facing the humanity. The vivid examples of the earthquake in Japan in March 2011 that generated a new kind of threat - the radiation pollution, and the events in the Arabic world that began in the same year, are dramatic evidences. By the middle of this century, the damage from such disastrous events is supposed to exceed the combined GDP of all countries of the world. The database of 287 large-scale natural and social disasters and global social phenomena that have occurred in the period of II B.C.E. - XXI A.D. was compiled by the authors for the first time. We have proposed the following phenomenological model: the scale of disasters over the time does not decrease, there is a minimum of accidents in the XV century; the numbers of accidents have cycles lasting until the first thousand years, natural and social disasters in the aggregate are uniformly distributed in time, but separately natural and social disasters are nonuniform. Thus, due to the evaluation, a 500-year cycle of catastrophes and 200-300 and 700-800-year periodicities are identified. It is shown that catastrophes are grouped into natural and social types by forming clusters. The hypothesis of the united geo-bio-social planetary process is founded. A fundamentally new feature of this research is the assumptions about the statistical significance of the biosphere and the impact of society on the geodynamic processes. The results allow to formulate a new understanding of global disaster as an event the damage from which the humanity will be unable to liquidate even by means of the total resource potential and the consequence of which may turn into the irreversible destruction of civilization. The correlation between the natural and social phenomena and the possible action mechanism is suggested.

    India and China are the 2 most populous countries of the world; in the 1950s, both countries initiated a centrally planned program for rapid development within vastly differing political systems. China embarked India's policy encouraged only voluntary acceptance of family planning. In both cases, however, government involvement in population forms a part of comprehensive national planning. Both countries rely on a limited resource base and technological sophistication in order to alleviate mass poverty and misery. The political implications of population growth cannot be neatly isolated from those that are generated by social and economic forces of change in a society that is in a transitional stage of modernization and development. Development has not been an unmixed bleesing; population growth is one of its counterproductive outcomes. The development process has begun to draw increasing attention to hitherto neglected correlates of fertility decline, such as a reduction in infant mortality, universal education, improvement in women's status, and women's participation in economic activity outside the home, all of which eventually result in greater demand for family planning services. Both the Indian and Chinese models highlight the importance of taking the people into one's confidence; the response of the common people to official initiatives is critical in securing a reduction in fertility levels. China has adopted a 1 child family policy, yet it is unreasonable to expect that the Indian people would agree to a nationally prescribed family size norm below 2 children. The principal determinant of future population trends in both these countries is the course of their politics. The success of developing countries will be assured if the developed nations support their progress without being worried about their population growth, which is the result of their unavoidable failure to modernize their social and economic structures.

    In the 1960s, "developmental biology" became the dominant term to describe some of the research that had previously been included under the rubrics of embryology, growth, morphology, and physiology. As scientific societies formed under this new label, a new discipline took shape. Historians, however, have a number of different perspectives on what changes led to this new field of developmental biology and how the field itself was constituted during this period. Using the General Embryological Information Service, a global index of post-World War II development-related research, we have documented and visualized significant changes in the kinds of research that occurred as this new field formed. In particular, our analysis supports the claim that the transition toward developmental biology was marked by a growth in new topics and forms of research. Although many historians privilege the role of molecular biology and/or the molecularization of biology in general during this formative period, we have found that the influence of molecular biology is not sufficient to account for the wide range of new research that constituted developmental biology at the time. Overall, our work creates a robust characterization of the changes that occurred with regard to research on growth and development in the decades following World War II and provides a context for future work on the specific drivers of those changes.

    NASA Astrophysics Data System (ADS)

    de Beer, Carel S.

    The theme 'knowledge society' can have many meanings depending on who defines it. But can knowledge really define society since there are many other qualifying adjectives for society as well. What one should be preferred? Is knowledge a better qualifying term than risk, information, technology, or any other one? These questions need answers. There are many dreams and counter dreams regarding the ideal society. Some dreams, like Unesco's dream, focus on the self-evident issues in the knowledge society, or what people consider to be self-evident, or what is taken for granted, as if no exploration is required: issues like access to knowledge, knowledge management, knowledge sharing, etc. These dreams contain a threat despite promises of a future that cannot be achieved. Other dreams, like those of Ars Industrialis, dig deeper and look for founding possibilities, take nothing for granted, search for the original, the defining principles. These dreams bring hope and light, a future to live for.

  20. Education in an Information Society

    Moore, John W.

    1999-04-01

    Last month's editorial pointed out that higher education may well change significantly as a result of the tremendous impact that information technologies are having on society. It quoted a white paper (1) by Russell Edgerton, Director of the Education Program of the Pew Charitable Trusts. Edgerton argued that higher education is currently failing to meet three challenges: to provide higher quality education; to reduce costs; and to regain its former stature as an important player in shaping public policy. Edgerton recommended that the Pew Trusts should encourage colleges and universities to set more ambitious goals for undergraduate education, to enter the public arena and play a major role in the reform of K-12 education, and to develop an academic profession interested in working toward these goals. Four new aims for undergraduate education were identified: "encouraging institutions to take learning seriously, encouraging faculty to take pedagogy seriously, demonstrating that technology can be used to reduce costs as well as to enhance learning, and developing new incentives for continuous quality improvement." One wonders why institutions of higher education should need to be encouraged toward goals that seem obviously congruent with their mission and self interest, but today's colleges and universities seem more likely to respond to outside offers of funding than to develop their own plans of action. As members of the faculty of such institutions, it behooves us to consider what some of those outside influences are likely to be and what effects they are likely to have on us, on our institutions, and on our students. Higher education is seen as a growth market by Michael Dolence and Donald Norris (2). In 1995 they projected that in five years there would be an increase of 20 million full-time equivalent enrollments in the U.S. and more than 100 million world wide. However, this growth was not projected to be traditional, on-campus students. Most was expected to

    This consensus document reviews the evidence on the evaluation of biological drugs. The main conclusions of the group are: a) the current evidence on biological comparisons is based on indirect comparisons and is generally unreliable and with important methodological limitations. Therefore, b) it is considered necessary to amend the regulatory directives in the sense of strongly favoring randomized non-inferiority studies comparing face to face the new biological treatment with current standards, avoiding trials versus placebo, c) A key element in this process will be determined by consensus among regulatory agencies, scientific societies, the pharmaceutical industry and health authorities regarding the clinical differences that should be considered relevant in each of the conditions tested.

    Within the framework of global biogeochemical cycles and ocean productivity, there are two areas that will be of particular interest to biological oceanography in the 1990s. The first is the mapping in space time of the biomass and productivity of phytoplankton in the world ocean. The second area is the coupling of biological and physical processes as it affects the distribution and growth rate of phytoplankton biomass. Certainly other areas will be of interest to biological oceanographers, but these two areas are amenable to observations from satellites. Temporal and spatial variability is a regular feature of marine ecosystems. The temporal and spatial variability of phytoplankton biomass and productivity which is ubiquitous at all time and space scales in the ocean must be characterized. Remote sensing from satellites addresses these problems with global observations of mesocale (2 to 20 days, 10 to 200 km) features over a long period of time.

    A biological preconcentrator comprises a stimulus-responsive active film on a stimulus-producing microfabricated platform. The active film can comprise a thermally switchable polymer film that can be used to selectively absorb and desorb proteins from a protein mixture. The biological microfabricated platform can comprise a thin membrane suspended on a substrate with an integral resistive heater and/or thermoelectric cooler for thermal switching of the active polymer film disposed on the membrane. The active polymer film can comprise hydrogel-like polymers, such as poly(ethylene oxide) or poly(n-isopropylacrylamide), that are tethered to the membrane. The biological preconcentrator can be fabricated with semiconductor materials and technologies.

    1984-06-01

    Recent research is reviewed from books, international committees and symposia which describes the usefulness of biological monitoring for exposure to such compounds as organometallic chemicals, carbon monoxide and cyanide. The types of analyses include the following measurements: the concentration of the chemical in various biological media such as blood, urine, and expired air; the concentration of metabolites of the individual chemical in the same media; and determination of nonadverse biological changes resulting from the reaction of the organism to exposure. A main goal of such monitoring is to ensure that the current or past levels of worker exposure are safe, so that such exposure does not involve an unacceptable health risk. It considers routes other than absorption by the lungs and is a good method for evaluating individual exposures.

    As the field of synthetic biology continues to define itself, it has merged concepts from many related areas of research: molecular biology, genetics, bioengineering, and chemistry. At the 2013 Spring American Chemical Society National Meeting in New Orleans, LA, this mixture was manifested in a wealth of sessions emphasizing the use of modern synthetic biological approaches to solve many of today's biggest chemical problems. As a result of the field's diverse yet pervasive nature, synthetic biology concepts were present in several of the conferences many divisions, including Biological Chemistry, Biochemical Technology, Cellulose and Renewable Materials, and several others. Here we offer a snapshot of some of the exciting research discussed in the dedicated synthetic biology sessions throughout the week.

    An overview is given of basic features of biological rhythms. The classification of periodic behavior of physical and psychological characteristics as circadian, circannual, diurnal, and ultradian is discussed, and the notion of relativistic time as it applies in biology is examined. Special attention is given to circadian rhythms which are dependent on the adrenocortical cycle. The need for adequate understanding of circadian variations in the basic physiological indicators of an individual (heart rate, body temperature, systolic and diastolic blood pressure, etc.) to ensure the effectiveness of prophylactic and therapeutic measures is stressed.

  7. Social Value Orientation and Capitalism in Societies

    2016-01-01

    Cooperation and competition are core issues in various fields, since they are claimed to affect the evolution of human societies and ecological organizations. A long-standing debate has existed on how social behaviors and preferences are shaped with culture. Considering the economic environment as part of culture, this study examines whether the ongoing modernization of competitive societies, called “capitalism,” affects the evolution of people’s social preferences and behaviors. To test this argument, we implemented field experiments of social value orientation and surveys with 1002 respondents for three different areas of Bangladesh: (i) rural, (ii) transitional and (iii) capitalistic societies. The main result reveals that with the evolution from rural to capitalistic societies, people are likely to be less prosocial and more likely to be competitive. In a transitional society, there is a considerable proportion of “unidentified” people, neither proself nor prosocial, implying the potential existence of unstable states during a transformation period from rural to capitalistic societies. We also find that people become more proself with increasing age, education and number of children. These results suggest that important environmental, climate change or sustainability problems, which require cooperation rather than competition, will pose more danger as societies become capitalistic.

    1999-04-01

    Last month's editorial pointed out that higher education may well change significantly as a result of the tremendous impact that information technologies are having on society. It quoted a white paper (1) by Russell Edgerton, Director of the Education Program of the Pew Charitable Trusts. Edgerton argued that higher education is currently failing to meet three challenges: to provide higher quality education; to reduce costs; and to regain its former stature as an important player in shaping public policy. Edgerton recommended that the Pew Trusts should encourage colleges and universities to set more ambitious goals for undergraduate education, to enter the public arena and play a major role in the reform of K-12 education, and to develop an academic profession interested in working toward these goals. Four new aims for undergraduate education were identified: "encouraging institutions to take learning seriously, encouraging faculty to take pedagogy seriously, demonstrating that technology can be used to reduce costs as well as to enhance learning, and developing new incentives for continuous quality improvement." One wonders why institutions of higher education should need to be encouraged toward goals that seem obviously congruent with their mission and self interest, but today's colleges and universities seem more likely to respond to outside offers of funding than to develop their own plans of action. As members of the faculty of such institutions, it behooves us to consider what some of those outside influences are likely to be and what effects they are likely to have on us, on our institutions, and on our students. Higher education is seen as a growth market by Michael Dolence and Donald Norris (2). In 1995 they projected that in five years there would be an increase of 20 million full-time equivalent enrollments in the U.S. and more than 100 million world wide. However, this growth was not projected to be traditional, on-campus students. Most was expected to

    Theory predicts that individuals' sexism serves to exacerbate inequality in their society's gender hierarchy. Past research, however, has provided only correlational evidence to support this hypothesis. In this study, I analyzed a large longitudinal data set that included representative data from 57 societies. Multilevel modeling showed that sexism directly predicted increases in gender inequality. This study provides the first evidence that sexist ideologies can create gender inequality within societies, and this finding suggests that sexism not only legitimizes the societal status quo, but also actively enhances the severity of the gender hierarchy. Three potential mechanisms for this effect are discussed briefly.

    The objective of creating Educational Standards of the Polish Pharmacoeconomic Society (Polish Chapter of the International Society for Pharmacoeconomics and Outcomes Research) was to define and establish a scope of knowledge and skills needed for people conducting and interpreting pharmacoeconomic analyses as well as health technology assessments. A Working Group of the Society identified target groups and divided the requirements into 3 groups: basic, intermediate and advanced. The document reflects conditions of the Polish healthcare and educational systems and is harmonized with international regulations in the field of pharmacoeconomics, outcomes research and health technology assessment. The standards may also serve as guidelines for educators in this area.

Last in time is the description of biological phenomena in terms of hybrids between an organism (scaffolded system) and a living or non-living scaffold, forming unit systems to study processes such as reproduction and development. As scaffold, eventually, we can define any resource used by the biological system, especially in development and reproduction, without incorporating it as happens in the case of resources fueling metabolism. Addressing biological systems as functionally scaffolded systems may help pointing to functional relationships that can impart temporal marking to the developmental process and thus explain its irreversibility; revisiting the boundary between development and metabolism and also regeneration phenomena, by suggesting a conceptual framework within which to investigate phenomena of regular hypermorphic regeneration such as characteristic of deer antlers; fixing a periodization of development in terms of the times at which a scaffolding relationship begins or is terminated; and promoting plant galls to legitimate study objects of developmental biology.

    The traveler attended the 1st International Conference on Biological Dosimetry in Madrid, Spain. This conference was organized to provide information to a general audience of biologists, physicists, radiotherapists, industrial hygiene personnel and individuals from related fields on the current ability of cytogenetic analysis to provide estimates of radiation dose in cases of occupational or environmental exposure. There is a growing interest in Spain in biological dosimetry because of the increased use of radiation sources for medical and occupational uses, and with this the anticipated and actual increase in numbers of overexposure. The traveler delivered the introductory lecture on Biological Dosimetry: Mechanistic Concepts'' that was intended to provide a framework by which the more applied lectures could be interpreted in a mechanistic way. A second component of the trip was to provide advice with regard to several recent cases of overexposure that had been or were being assessed by the Radiopathology and Radiotherapy Department of the Hospital General Gregorio Maranon'' in Madrid. The traveler had provided information on several of these, and had analyzed cells from some exposed or purportedly exposed individuals. The members of the biological dosimetry group were referred to individuals at REACTS at Oak Ridge Associated Universities for advice on follow-up treatment.

    Sverdrup's contribution to Biological Oceanography were more than merely substantial, they were of fundamental importance. His plan for the training of graduate students at Scripps did not recognize the traditional division of the basic disciplines into separate categories of physics, chemistry, biology and geology. He insisted that Oceanography was a multi-disciplinary subject and that all entering students should study all four subjects. Today this is not very unusual but it was in the early 50s when I took those courses. We biologists carried away from those courses an appreciation of the importance of both spatial and temporal scale. It was of clear relevance to problems of oceanic population and community biology. But there was still more to his biology. He is responsible for a very simple, but very elegant model of the regulation of oceanic primary productivity. The elements of this model are found today in the ten or so highly derivative models. He also published a map predicting global ocean productivity based on the ideas in the model plus some wonderfully intuitive thinking. This map does not differ strongly from those glorious false color ones being published today.

    Summary This report considers the recommendations of the State Society Task Force (SSTF), which evaluated how the relationship between the American Academy of Neurology (AAN) and neurologic societies of individual states can foster the care of patients with neurologic diseases. The task force also evaluated the role of state neurosociety and state medical society interactions in supporting the profession of neurology. The SSTF recommended that the AAN expand current support services to state neurosocieties and foster additional neurosociety development. Specific services to be considered by the AAN include online combined AAN/state neurosociety dues payment and enhanced Web support. The role of the AAN as a liaison between state neurosocieties and state medical societies is important to facilitate state level advocacy for neurology. PMID:25110622

    The Congenital Heart Surgeons' Society is a group of over 100 pediatric heart surgeons representing 72 institutions that specialize in the treatment of patients with congenital heart defects. The Society began in 1972 and incorporated as a not-for-profit charitable organization in 2004. It has become the face and voice of congenital heart surgery in North America. In 1985, the Society established a data center for multicenter clinical research studies to encourage congenital heart professionals to participate in improving outcomes for our patients. The goals of the Congenital Heart Surgeons' Society are to stimulate the study of congenital cardiac physiology, pathology, and management options which are instantiated in data collection, multi-institutional studies, and scientific meetings. Honest and open discussion of problems with possible solutions to the challenges facing congenital heart professionals have been the strength of the Congenital Heart Surgeons' Society. It is imperative for the growth of an organization to know from where it came in order to know to where it is going. The purpose of this article is to review the history of the Congenital Heart Surgeons' Society.

  20. Sustainable Society Formed by Unselfish Agents

    NASA Astrophysics Data System (ADS)

    Kikuchi, Toshiko

    It has been pointed out that if the social configuration of the three relations (market, communal and obligatory relations) is not balanced, a market based society as a total system fails. Using multi-agent simulations, this paper shows that a sustainable society is formed when all three relations are integrated and function respectively. When agent trades are based on the market mechanism (i.e., agents act in their own interest and thus only market relations exist), weak agents who cannot perform transactions die. If a compulsory tax is imposed to enable all weak agents to survive (i.e., obligatory relations exist), then the fiscal deficit increases. On the other hand, if agents who have excess income undertake the unselfish action of distributing their surplus to the weak agents (i.e., communal relations exist), then trade volume increases. It is shown that the existence of unselfish agents is necessary for the realization of a sustainable society. However, the survival of all agents is difficult in a communal society. In an artificial society, for all agents survive and fiscal balance to be maintained, all three social relations need to be fully integrated. These results show that adjusting the balance of the three social relations well lead to the realization of a sustainable society.

    PubMed

    Couet, D; Lecorps, P

    1985-01-01

    This volume is written for those who are interested in sex education. The 1st part discusses specifically educational questions: what does sex education have to offer; what is sex education (information or education, and the objectives of sex education); the roles of the adult educator (encountering, listening, answering); and training the educator. Part 2 contains a series of teachers' aid sheets, followed by notes on the subject for the teacher. The 3rd part describes the experiences of 1 country, Burkina Faso, as analyzed by those in charge of it and provides the complete text of 1 of the 3 "theatre-forum" plays written and used there in the framework of their program. The overall objective of education in sexuality is to enable the participants to find their place as sexual beings, maintaining relationships with other human beings within a given society and culture. The realization of this objective requires that young people: 1) discuss their own questions and preoccupations with respect to sexuality, the family and society, in the context of their own personal and collective history; 2) learn factual information on biology and understand their own society (e.g., traditional values, political orientations); and 3) debate among themselves and with an adult the question of a rational ethical system based on the identification and acceptance of shared values. Thus educational action should contribute to 2 sorts of elements: pieces of information on the entire field of human sexuality, the family, and society (biology, psychology, and sociology); and elements of reflection on human sexuality with its impact on the community (the roles of men and women, values and traditions, the circumstances surrounding love life, and the education of children).

    Summary The inhibitor of nuclear factor-κB (IκB) kinase (IKK) complex is the master regulator of the NF-κB signaling pathway. The activation of the IKK complex is a tightly regulated, highly stimulus-specific, and target-specific event that is essential for the plethora of functions attributed to NF-κB. More recently, NF-κB independent roles of IKK members have brought increased complexity to its biological function. This review highlights some of the major advances in the studies of the process of IKK activation and the biological roles of IKK family members, with a focus on NF-κB independent functions. Understanding these complex processes is essential for targeting IKK for therapeutics. PMID:22435559

    Biological soil crusts, a community of cyanobacteria, lichens, mosses, and fungi, are an essential part of dryland ecosystems. They are critical in the stabilization of soils, protecting them from wind and water erosion. Similarly, these soil surface communities also stabilized soils on early Earth, allowing vascular plants to establish. They contribute nitrogen and carbon to otherwise relatively infertile dryland soils, and have a strong influence on hydrologic cycles. Their presence can also influence vascular plant establishment and nutrition.

  7. Toward the high-environment society from the high-information society

    NASA Astrophysics Data System (ADS)

    Aiso, Hideo

    The society in the 21st century may be cal[ed 'high-environmental society', in which information science and technology will play an essential role in creating new environments. 'Environments' in this context mean the whole outside world which is perceived by a human being, a living body, or a machine (these are 'systems' in a broad sense). The infrastructures needed for creation of the high-environmental society and plans for entering this society are discussed. In the high-environmental society, information environments and artificial environments will be greatly improved besides natural, living, and organizational environments. We should build the technological, social, and educational infrastructures for this society so that we can live a good life together with all environments.

    2014-12-01

    As the first program of its kind, the M.A. in Climate and Society at Columbia University educates students on how climate affects society and vice versa. The 12-month interdisciplinary Master's program is designed to allow students from a wide variety of backgrounds to gain knowledge in climate science and a deep understanding of social sciences and how they related to climate. There are currently more than 250 alumni applying their skills in fields including energy, economics, disaster mitigation, journalism and climate research in more than a dozen countries worldwide. The presentation will highlight three key components of the program that have contributed to its growth and helped alumni become brokers that can effectively put climate science in the hands of the public and policymakers for the benefit of society. Those components include working with other academic departments at Columbia to successfully integrate social science classes into the curriculum; the development of the course Applications in Climate and Society to help students make an overt link between climate and its impacts on society; and providing students with hands-on activities with practitioners in climate-related fields.

  10. Impacting Society through Astronomy Undergraduate Courses

    NASA Astrophysics Data System (ADS)

    Schleigh, Sharon

    2015-04-01

    A high percentage of non-science majors enroll in undergraduate, introductory astronomy courses across the country. The perception of the astronomy course as being easier than the ``hard sciences'' and the idea that the course will focus on ``pretty pictures'', influences the interests of the non-science majors. Often the students that enroll in these courses will not take other science courses, resulting in the only opportunity to teach college students about basic scientific concepts that impact their lives. Vast misconceptions about the nature of science, the role of science and scientists in society, and social issues embedded in scientific information, impact the decisions that individuals make about every day events. In turn, these decisions influence the policies that construct our society. This talk will provide an overview of the common misconceptions and discuss how they impact our society as a whole. The research presented provides evidence of the impact that introductory college astronomy courses have on changing these everyday misconceptions and influencing non-science majors' ideas about science in society. The research suggests that introductory courses designed for non-science majors are extremely important in impacting our society, and begs for a stronger understanding and implementation of best practices for teaching and learning in the college classroom environment.

  11. Fifty Years of the Korean Society for Parasitology

    2009-01-01

    In 1959, the Korean Society for Parasitology was founded by clinical scientists, specialists of public health, and 5 core parasitologists with experience in American science and medicine. The Society this year celebrates its 50th anniversary. Due to public health importance at the time of foundation, medical parasitology was the main stream for next 3 decades. Domestic problems of niche parasitic diseases, unlisted in 6 tropical diseases of major importance, had been studied by own efforts. To cope with the demand of parasite control, evaluation system for control activity was built up. Control activity against soil-transmitted nematodes, conducted for almost 3 decades, was evaluated as a success. Evaluation of praziquantel efficacy for clonorchiasis, paragonimiasis, and neurocysticercosis, population dynamics of Ascaris lumbricoides infection in a situation of continuous reinfections, diagnostic modalities of antibody tests combined with brain imaging developed for helminthiasis of the central nervous system and researches on intestinal trematodes were achievements in the first 30 years. During the recent 2 decades, science researches, such as cell and molecular biology of parasites and immunology of parasitic infections have been studied especially on parasitic allergens and proteolytic and anti-oxidant enzymes. Experiences of international cooperation for world health have been accumulated and would be expanded in the future. PMID:19885338

    This paper studied associations between ocular symptoms, rhinitis, throat and dermal symptoms, headache and fatigue in students by ethnicity and in relation to exposure to chemical microbial markers and fungal DNA in vacuumed dust in schools in Malaysia. A total of 462 students from 8 randomly selected secondary schools in Johor Bahru, Malaysia, participated (96% response rate). Dust was vacuumed from 32 classrooms and analysed for levels of five types of endotoxin as 3-hydroxy fatty acids (C10, C12, C14, C16 and C18 3-OH), muramic acid, ergosterol and five sequences of fungal DNA. Multiple logistic regression was applied. Totally 11.9% reported weekly ocular symptoms, 18.8% rhinitis, 15.6% throat and 11.1% dermal symptoms, 20.6% headache and 22.1% tiredness. Totally 21.1% reported pollen or furry pet allergy (atopy) and 22.0% parental asthma or allergy. Chinese students had less headache than Malay and Indian had less rhinitis and less tiredness than Malay. Parental asthma/allergy was a risk factor for ocular (odds ratio=3.79) and rhinitis symptoms (OR=3.48). Atopy was a risk factor for throat symptoms (OR=2.66), headache (OR=2.13) and tiredness (OR=2.02). There were positive associations between amount of fine dust in the dust samples and ocular symptoms (p<0.001) and rhinitis (p=0.006). There were positive associations between C14 3-OH and rhinitis (p<0.001) and between C18 3-OH and dermal symptoms (p=0.007). There were negative (protective) associations between levels of total endotoxin (LPS) (p=0.004) and levels of ergosterol (p=0.03) and rhinitis and between C12 3-OH and throat symptoms (p=0.004). In conclusion, the amount of fine dust in the classroom was associated with rhinitis and other SBS symptoms and improved cleaning of the schools is important. Endotoxin in the school dust seems to be mainly protective for rhinitis and throat symptoms but different types of endotoxin could have different effects. The ethnic differences in symptoms among the students

  14. On Beyond Star Trek, the Role of Synthetic Biology in Nasa's Missions

    Rothschild, Lynn J.

    2016-01-01

    The time has come to for NASA to exploit the nascent field of synthetic biology in pursuit of its mission, including aeronautics, earth science, astrobiology and notably, human exploration. Conversely, NASA advances the fundamental technology of synthetic biology as no one else can because of its unique expertise in the origin of life and life in extreme environments, including the potential for alternate life forms. This enables unique, creative "game changing" advances. NASA's requirement for minimizing upmass in flight will also drive the field toward miniaturization and automation. These drivers will greatly increase the utility of synthetic biology solutions for military, health in remote areas and commercial purposes. To this end, we have begun a program at NASA to explore the use of synthetic biology in NASA's missions, particularly space exploration. As part of this program, we began hosting an iGEM team of undergraduates drawn from Brown and Stanford Universities to conduct synthetic biology research at NASA Ames Research Center. The 2011 team (http://2011.igem.org/Team:Brown-Stanford) produced an award-winning project on using synthetic biology as a basis for a human Mars settlement and the 2012 team has expanded the use of synthetic biology to estimate the potential for life in the clouds of other planets (http://2012.igem.org/Team:Stanford-Brown; http://www.calacademy.org/sciencetoday/igem-competition/). More recent projects from the Stanford-Brown team have expanded our ideas of how synthetic biology can aid NASA's missions from "Synthetic BioCommunication" (http://2013.igem.org/Team:Stanford-Brown) to a "Biodegradable UAS (drone)" in collaboration with Spelman College (http://2014.igem.org/Team:StanfordBrownSpelman#SBS%20iGEM) and most recently, "Self-Folding Origami" (http://2015.igem.org/Team:Stanford-Brown), the winner of the 2015 award for Manufacturing.

  15. Nicholson Medal Lecture: Scientists and Totalitarian Societies

    NASA Astrophysics Data System (ADS)

    Fang, Li-Zhi

    1997-04-01

    In order to call for support for his policy in China from the scientific community outside of China, Li Peng, China's premier today and at the time of Tiananmen massacre in 1989, published an editorial of ``Science" magazine (July 5, 1996) titled ``Why China needs science ... and partners." This editorial brought a serious problem, which is originally faced by scientists in a totalitarian society, upon the scientific community in free societies outside. It is well known that the current attitude of the Chinese government toward science is what it was during the years of Mao and the Soviet Union: science is limited to provide instruments useful to the rulers, but any degree of freedom, such as to challenge ideas, required by science to change the totalitarian regime itself, is suppressed. Thus, the problem facing us is: how to help your colleagues and promote science in a totalitarian society, without becoming a partner of the injustices of that regime.

  16. Mineral resources of Peru's ancient societies

    USGS Publications Warehouse

    Brooks, W.E.

    2003-01-01

    Northern Peru has an exceptionally rich archaeological heritage that includes metalwork, ceramics and textiles. The success of at least a half-dozen pre-Columbian societies dating back 3,000 years and subsequent Spanish colonization in the 1400s has rested on the effective use of northern Peru's abundant resources. In the summer of 2000, my son Matt and I learned about that connection firsthand by volunteering at the Santa Rita B archaeological site in the Chao Valley near Trujillo in northern Peru. Riding donkey-back through the Andes and talking with local people, we got our hands dirty in the rich archaeology and geology of the area. We were able to correlate mineral occurrences to their various roles in society - opening a window into the region's fascinating past. From construction to metallurgy, pre-Columbian societies flourished and advanced because of their understanding and use of the available mineral resources.

  17. Longevity suppresses conflict in animal societies.

    PubMed

    Port, Markus; Cant, Michael A

    2013-10-23

    Models of social conflict in animal societies generally assume that within-group conflict reduces the value of a communal resource. For many animals, however, the primary cost of conflict is increased mortality. We develop a simple inclusive fitness model of social conflict that takes this cost into account. We show that longevity substantially reduces the level of within-group conflict, which can lead to the evolution of peaceful animal societies if relatedness among group members is high. By contrast, peaceful outcomes are never possible in models where the primary cost of social conflict is resource depletion. Incorporating mortality costs into models of social conflict can explain why many animal societies are so remarkably peaceful despite great potential for conflict.

  18. [High-performance society and doping].

    PubMed

    Gallien, C L

    2002-09-01

    Doping is not limited to high-level athletes. Likewise it is not limited to the field of sports activities. The doping phenomenon observed in sports actually reveals an underlying question concerning the notion of sports itself, and more widely, the society's conception of sports. In a high-performance society, which is also a high-risk society, doping behavior is observed in a large number of persons who may or may not participate in sports activities. The motivation is the search for individual success or profit. The fight against doping must therefore focus on individual responsibility and prevention in order to preserve athlete's health and maintain the ethical and educational value of sports activities.

    Pavan, R

    1987-04-01

    The author takes the main themes of an International Colloquium held in Toulouse on 15 June 1984 as a starting point to present some reflections on aging. In particular the need for aged societies to face important problems regarding dynamism is stressed, in order to maintain a confrontation with other, younger, societies and to provide people with the same levels of welfare. Moreover, in the future, towns will be more compact with less space so that within a limited environment the elderly individual--whose degree of mobility is ever-decreasing--can carry out his daily activities independently and with ease. From now on, collective savings--adequately invested in production--can assure economic development and a pension system worthy of a progressively aging society.

    This article theorizes civil society groups' attempts to popularize opposition to genetic modification in New Zealand as deliberative interventions that seek to open up public participation in science-society governance. In this case, the popularization strategies were designed to intensify concerns about social justice and democratic incursions, mobilize dissent and offer meaningful mechanisms for navigating and participating in public protest. Such civic popularization efforts, we argue, are more likely to succeed when popularity and politicization strategies are judiciously integrated to escalate controversy, re-negotiate power relations and provoke agency and action.

  3. Biological membranes

    PubMed Central

    Watson, Helen

    2015-01-01

    Biological membranes allow life as we know it to exist. They form cells and enable separation between the inside and outside of an organism, controlling by means of their selective permeability which substances enter and leave. By allowing gradients of ions to be created across them, membranes also enable living organisms to generate energy. In addition, they control the flow of messages between cells by sending, receiving and processing information in the form of chemical and electrical signals. This essay summarizes the structure and function of membranes and the proteins within them, and describes their role in trafficking and transport, and their involvement in health and disease. Techniques for studying membranes are also discussed. PMID:26504250

    2013-06-01

    Biotechnological and life science innovations do not only lead to immense progress in diverse fields of natural science and technical research and thereby drive economic development, they also fundamentally affect the relationship between nature, technology and society. Taken this seriously, the ethical and societal assessment of emerging biotechnologies as for example synthetic biology is challenged not only to constrain on questions of biosafety and biosecurity but also to face the societal questions within the different fields as an interface problem of science and society. In order to map this vague and stirring field, we propose the concept of bio-objects to explore the reciprocal interaction at the interface of science and society serious as well to have the opportunity to detect possible junctions of societal discontent and unease before their appearance.

  20. Margaret Cavendish and the Royal Society.

    PubMed

    Wilkins, Emma

    2014-09-20

    It is often claimed that Margaret Cavendish was an anti-experimentalist who was deeply hostile to the activities of the early Royal Society--particularly in relation to Robert Hooke's experiments with microscopes. Some scholars have argued that her views were odd or even childish, while others have claimed that they were shaped by her gender-based status as a scientific 'outsider'. In this paper I examine Cavendish's views in contemporary context, arguing that her relationship with the Royal Society was more nuanced than previous accounts have suggested. This contextualized approach reveals two points: first, that Cavendish's views were not isolated or odd when compared with those of her contemporaries, and second, that the early Royal Society was less intellectually homogeneous than is sometimes thought. I also show that, although hostile to some aspects of experimentalism, Cavendish nevertheless shared many of the Royal Society's ambitions for natural philosophy, especially in relation to its usefulness and the importance of plain language as a means to disseminate new ideas.

  5. Matrilocal residence is ancestral in Austronesian societies.

    PubMed

    Jordan, Fiona M; Gray, Russell D; Greenhill, Simon J; Mace, Ruth

    2009-06-01

    The nature of social life in human prehistory is elusive, yet knowing how kinship systems evolve is critical for understanding population history and cultural diversity. Post-marital residence rules specify sex-specific dispersal and kin association, influencing the pattern of genetic markers across populations. Cultural phylogenetics allows us to practise 'virtual archaeology' on these aspects of social life that leave no trace in the archaeological record. Here we show that early Austronesian societies practised matrilocal post-marital residence. Using a Markov-chain Monte Carlo comparative method implemented in a Bayesian phylogenetic framework, we estimated the type of residence at each ancestral node in a sample of Austronesian language trees spanning 135 Pacific societies. Matrilocal residence has been hypothesized for proto-Oceanic society (ca 3500 BP), but we find strong evidence that matrilocality was predominant in earlier Austronesian societies ca 5000-4500 BP, at the root of the language family and its early branches. Our results illuminate the divergent patterns of mtDNA and Y-chromosome markers seen in the Pacific. The analysis of present-day cross-cultural data in this way allows us to directly address cultural evolutionary and life-history processes in prehistory.

  2. Margaret Cavendish and the Royal Society.

    PubMed

    Wilkins, Emma

    2014-09-20

    It is often claimed that Margaret Cavendish was an anti-experimentalist who was deeply hostile to the activities of the early Royal Society--particularly in relation to Robert Hooke's experiments with microscopes. Some scholars have argued that her views were odd or even childish, while others have claimed that they were shaped by her gender-based status as a scientific 'outsider'. In this paper I examine Cavendish's views in contemporary context, arguing that her relationship with the Royal Society was more nuanced than previous accounts have suggested. This contextualized approach reveals two points: first, that Cavendish's views were not isolated or odd when compared with those of her contemporaries, and second, that the early Royal Society was less intellectually homogeneous than is sometimes thought. I also show that, although hostile to some aspects of experimentalism, Cavendish nevertheless shared many of the Royal Society's ambitions for natural philosophy, especially in relation to its usefulness and the importance of plain language as a means to disseminate new ideas.

  18. Biological warfare, bioterrorism, and biocrime.

    PubMed

    Jansen, H J; Breeveld, F J; Stijnis, C; Grobusch, M P

    Biological weapons achieve their intended target effects through the infectivity of disease-causing infectious agents. The ability to use biological agents in warfare is prohibited by the Biological and Toxin Weapon Convention. Bioterrorism is defined as the deliberate release of viruses, bacteria or other agents used to cause illness or death in people, but also in animals or plants. It is aimed at creating casualties, terror, societal disruption, or economic loss, inspired by ideological, religious or political beliefs. The success of bioterroristic attempts is defined by the measure of societal disruption and panic, and not necessarily by the sheer number of casualties. Thus, making only a few individuals ill by the use of crude methods may be sufficient, as long as it creates the impact that is aimed for. The assessment of bioterrorism threats and motives have been described before. Biocrime implies the use of a biological agent to kill or make ill a single individual or small group of individuals, motivated by revenge or the desire for monetary gain by extortion, rather than by political, ideological, religious or other beliefs. The likelihood of a successful bioterrorist attack is not very large, given the technical difficulties and constraints. However, even if the number of casualties is likely to be limited, the impact of a bioterrorist attack can still be high. Measures aimed at enhancing diagnostic and therapeutic capabilities and capacities alongside training and education will improve the ability of society to combat 'regular' infectious diseases outbreaks, as well as mitigating the effects of bioterrorist attacks.

  19. !Kung nutritional status and the original "affluent society"--a new analysis.

    PubMed

    Bogin, Barry

    2011-01-01

    The theme of the 2011 meetings of the German Anthropological Society, "Biological and Cultural Markers of Environmental Pressure", provides the entree to revisit one of Anthropology's most enduring canons - hunters and gathers are well-nourished and healthy. The Dobe !Kung foragers of the Kalahari Desert often serve as a model of hunter-gatherer adaptation for both extant and Paleolithic humans. A re-analysis of food intake, energy expenditure, and demographic data collected in the 1960s for the Dobe !Kung finds that their biocultural indicators of nutritional status and health were, at best, precarious and, at worst, indicative of a society in danger of extinction. Hunting and gathering is the lifestyle to which the human species was most persistently adapted, in terms of the biological, cultural, and emotional meanings of the word 'adapted.' However, the few remaining foraging groups studied in the 20th Century are unlikely to serve as the ideal models of that ancient way of life.

  20. Structural genomics for science and society.

    The field of robotics is affecting structural biology, enabling the era of structural genomics. The potential impact on protein fold prediction, biology, protein engineering and medicine is immense. Unraveling mysteries in the protein structure universe will require a dedicated effort for decades to come with computational toxicology as possibly a century long challenge.
