  2. EDRN Longitudinal Serum Biorepository — EDRN Public Portal

    Science.gov (United States)

    Four percent of EDRN Registry mutation carriers developed cancer within a year after beginning follow-up in this registry; within 2 years, 10% had developed cancer. Within 2 years, 17% had developed either a cancer or a pre-malignant lesion (e.g. adenoma). Our goal is to recruit 265 mutation carriers from the EDRN High Risk Registry and Hereditary Cancer Center for the Longitudinal Serum Biorepository (LSB). Based on the cancer rates observed to date in the EDRN Registry, four years of follow-up in a group of this size would be expected to yield 53 invasive and in situ cancers and 37 benign premalignant lesions. All subjects in the serum biorepository (1)have signed consent (2) are counseled carriers (APC, BRCA1, BRCA2, CDH1, CDKN2A, MLH1, MSH2, MSH6) and (3) are enrolled in family studies through CU's Department of Preventive Medicine and/or are enrolled in the EDRN High Risk Registry. Post specimen medical history is collected annually. Serum and plasma are aliquoted for respository storage and stored in labeled cryovials in an ultra low temperature (-86C) freezer. Specimens in the LSB are available for use in EDRN biomarker development and validation studies.

  3. EDRN Pre-Validation of Multiplex Biomarker in Urine — EDRN Public Portal

    Science.gov (United States)

    The goal of this proposal is to begin to establish an EDRN “pre-validation” trial of a multiplex set of transcripts, including the ETS gene fusions, in post-DRE urine sediments. As can be evidenced by our preliminary data, we have established the utility of this multiplex urine test (which includes TMPRSS-ERG, SPINK1, PCA3 and GOLPH2) in a cohort of prospectively collected urine sediments from the University of Michigan EDRN CEVC site (collected by co-I, Dr. John Wei). In this proposal, we will run this multiplex assay on prospectively collected post-DRE urines collected from other EDRN sites. The idea is to couple this “pre-validation” study with an EDRN validation trial under consideration for the Gen-Probe PCA3 urine test (directed by Drs. John Wei and Harry Rittenhouse).

    2015-06-01

    The commercial market offers several software packages for the registration of remotely sensed data through standard one-to-one image matching. Although very rapid and simple, this strategy does not take into consideration all the interconnections among the images of a multi-temporal data set. This paper presents a new scientific software, called Satellite Automatic Multi-Image Registration (SAMIR), able to extend the traditional registration approach towards multi-image global processing. Tests carried out with high-resolution optical (IKONOS) and high-resolution radar (COSMO-SkyMed) data showed that SAMIR can improve the registration phase with a more rigorous and robust workflow without initial approximations, user's interaction or limitation in spatial/spectral data size. The validation highlighted a sub-pixel accuracy in image co-registration for the considered imaging technologies, including optical and radar imagery.

  5. Remote sensing of atmospheric water content from Bhaskara SAMIR data. [using statistical linear regression analysis

    1982-01-01

    The 19.35 GHz and 22.235 GHz passive microwave radiometers (SAMIR) on board the Indian satellite Bhaskara have provided very useful data. From these data has been demonstrated the feasibility of deriving atmospheric and ocean surface parameters such as water vapor content, liquid water content, rainfall rate and ocean surface winds. Different approaches have been tried for deriving the atmospheric water content. The statistical and empirical methods have been used by others for the analysis of the Nimbus data. A simulation technique has been attempted for the first time for 19.35 GHz and 22.235 GHz radiometer data. The results obtained from three different methods are compared with radiosonde data. A case study of a tropical depression has been undertaken to demonstrate the capability of Bhaskara SAMIR data to show the variation of total water vapor and liquid water contents.

  7. Early Detection of Cancer by Affinity Mass Spectrometry-Set Aside funds — EDRN Public Portal

    Science.gov (United States)

    A.   RATIONALE The recent introduction of multiple reaction monitoring capabilities offers unprecedented capability to the research arsenal available to protein based biomarker discovery. Specific to the discovery process this technology offers an ability to monitor specific protein changes in concentration and/or post-translational modification. The ability to accurately confirm specific biomarkers in a sensitive and reproducible manner is critical to the confirmation and pre-validation process. We are proposing two collaborative studies that promise to develop Multiple Reaction Monitoring (MRM) work flows for the biomarker scientific community and specifically for EDRN. B.   GOALS The overall goal for this proposal is the identification of protein biomarkers that can be associated with prostate cancer detection. The underlying goal is the application of a novel technological approach aided by MRM toward biomarker discovery. An additional goal will be the dissemination of knowledge gained from these studies EDRN wide.

  8. Validation of Early Detection Ovarian Cancer Biomarkers (Team Project) — EDRN Public Portal

    Science.gov (United States)

    Early detection of Ovarian Cancer (OC) is one of the key clinical problems in this disease. We propose a team EDRN project to address the issue of early detection of OC by performing a validation study on candidate protein markers already identified in previous EDRN research or in the literature (e.g. protein products of TCGA identified mutations specific to ovarian cancer). (See appendix for full listing) Biospecimen sources have been identified which include samples obtained at diagnosis and matched controls (Urban, Godwin, Marks, Skates), and longitudinal samples obtained prior to diagnosis (Urban, Skates, Godwin). Bioinformatic filters will be applied to rank the candidates (Diamandis). In order of ranking, candidate proteins for which high quality antibodies are available will be measured by development of ELISAs at JHU (Chan/Zhang) or through NAPPA at DFCI (Anderson/LaBaer), while for other candidates mass spectrometry based selective reaction monitoring (SRM) assays will be developed at PNNL (Rodland). Three milestones are defined. The first two milestones are to assemble the necessary specimens and to develop the qualifying assay(s). The final milestone is to estimate the markers’ sensitivity one year prior to diagnosis at a given high specificity.

  9. Liver Rapid Reference Set Application: Hemken - Abbott (2015) — EDRN Public Portal

    Science.gov (United States)

    The aim for this testing is to find a small panel of biomarkers (n=2-5) that can be tested on the Abbott ARCHITECT automated immunoassay platform for the early detection of hepatocellular carcinoma (HCC). This panel of biomarkers should perform significantly better than alpha-fetoprotein (AFP) alone based on multivariate statistical analysis. This testing of the EDRN reference set will help expedite the selection of a small panel of ARCHITECT biomarkers for the early detection of HCC. The panel of ARCHITECT biomarkers Abbott plans to test include: AFP, protein induced by vitamin K absence or antagonist-II (PIVKA-II), golgi protein 73 (GP73), hepatocellular growth factor (HGF), dipeptidyl peptidase 4 (DPP4) and DPP4/seprase (surface expressed protease) heterodimer hybrid. PIVKA-II is abnormal des-carboxylated prothrombin (DCP) present in vitamin K deficiency.

  10. Liver Full Reference Set Application: Hiro Yamada - Wako (2011) — EDRN Public Portal

    Science.gov (United States)

    Wako has received new 510(k) clearance for Lens culinaris agglutinin-reactive fraction of alpha-fetoprotein (AFP-L3) and Des-gamma-carboxy prothrombin (DCP) tests on an innovative μTASWako i30 analyzer from FDA. The AFP-L3 and DCP assayed on an older platform LiBASys have been cleared with indication of use for risk assessment of hepatocellular carcinoma (HCC) in patient at risk for the liver malignancy. Wako believes that early detection of HCC is critical for improving HCC patient outcome. Therefore, Wako is currently seeking collaborative opportunities to retrospectively measure clinical samples using the AFP-L3 and DCP for further determining of effectiveness of the HCC biomarkers in early detection which are collected prospectively during HCC surveillance. The Reference Sample Set in the EDRN biorepository are well characterized and studied. Access to these samples would allow Wako to quickly determine the clinical effectiveness of AFP-L3 and DCP in detecting early HCC

  11. A Virtual Bioinformatics Knowledge Environment for Early Cancer Detection

    Science.gov (United States)

    Crichton, Daniel; Srivastava, Sudhir; Johnsey, Donald

    2003-01-01

    Discovery of disease biomarkers for cancer is a leading focus of early detection. The National Cancer Institute created a network of collaborating institutions focused on the discovery and validation of cancer biomarkers called the Early Detection Research Network (EDRN). Informatics plays a key role in enabling a virtual knowledge environment that provides scientists real time access to distributed data sets located at research institutions across the nation. The distributed and heterogeneous nature of the collaboration makes data sharing across institutions very difficult. EDRN has developed a comprehensive informatics effort focused on developing a national infrastructure enabling seamless access, sharing and discovery of science data resources across all EDRN sites. This paper will discuss the EDRN knowledge system architecture, its objectives and its accomplishments.

    2012-01-01

    For the past decade, the NASA Jet Propulsion Laboratory, in collaboration with Dartmouth University has served as the center for informatics for the Early Detection Research Network (EDRN). The EDRN is a multi-institution research effort funded by the U.S. National Cancer Institute (NCI) and tasked with identifying and validating biomarkers for the early detection of cancer. As the distributed network has grown, increasingly formal processes have been developed for the acquisition, curation, storage, and dissemination of heterogeneous research information assets, and an informatics infrastructure has emerged. In this paper we discuss the evolution of EDRN informatics, its success as a mechanism for distributed information integration, and the potential sustainability and reuse benefits of emerging efforts to make the platform components themselves open source. We describe our experience transitioning a large closed-source software system to a community driven, open source project at the Apache Software Foundation, and point to lessons learned that will guide our present efforts to promote the reuse of the EDRN informatics infrastructure by a broader community.

    We show in the context of potential theory, first, why the SVZ procedure for calculating hadronic masses succeeds phenomenologically: it provides a semiclassical interpolating formula which correctly relates input masses to output masses; and second, why it fails theoretically: the potential (or QCD) parameters derived from fits to masses are necessarily different from the true parameters.

    Huntington, S.P.

    1993-01-01

    Does international primacy matter? The answer seems so obvious that one first wonders why someone as intelligent, perceptive, and knowledgeable as Robert Jervis raises the question. On further thought, however, one sees that while the answer may be obvious for most people, the reasons why it is obvious may not be all that clear and may have been forgotten or lost in the other concerns of political scientists and economists studying international relations. By posing this question at this time of change in world affairs Jervis has constructively forced us to rethink why primacy is of central importance. This issue involves several subordinate questions

  2. The woman patient after WHI.

    Science.gov (United States)

    Graziottin, Alessandra

    2005-05-16

    An epidemic of fear and distrust has infected women (and physicians) after publication of the Women's Health Initiative (WHI). The overinflated negative data emerging from the oestroprogestinic arm of WHI have frightened women and gave rise to the most difficult emotions to cope with. Keywords such as cancer, death and hormones combined together, have potentiated an avoidant attitude towards hormonal therapy (HT) driven more emotionally than rationally. This negative aura has not been dissipated by the positive data from the oestrogen-only arm of WHI. This paper will discuss: women's different emotional reactions to and coping strategies for HT-related fear after WHI; the communication skills physicians should use in focusing on positive messages emerging from WHI; predictors of current HT use; the meaning of the higher use of HT in postmenopausal highly-educated women and women gynaecologists; the importance of increasing healthy life-styles as a taking of responsibility towards aging by every woman; shifting from passivity to active sharing of the decision making process with the caring physician; and the use of an individually tailored HT, when appropriate, as part of an active strategy in the pursuit of a longer health expectancy.

  7. Communicating why land surface heterogeneity matters

    Science.gov (United States)

    Tague, C.; Burke, W.; Bart, R. R.; Turpin, E.; Wood, T.; Gordon, D.

    2017-12-01

    As hydrologic scientists, we know that land surface heterogeneity can have nuanced and sometimes dramatic impacts on the water cycle. Land surface characteristics, including the structure and composition of vegetation and soil storage and drainage properties, alter how incoming precipitation is translated into streamflow and evapotranspiration. Land surface heterogeneity can explain why this partitioning of incoming precipitation cannot always be computed by a simple water budget calculation. We also know that land surface characteristics are dynamic - vegetation grows and changes with fire, disease and human actions and these changes will alter the partitioning of water - how much so, however depends itself on other site characteristics - soil water storage and the timing and magnitude of precipitation. This complex impact of space-time dynamics on the water cycle is something we need to effectively communicate to non-experts. For example, we may want to explain why sometimes forest management practices increase water availability but sometimes they don't - or why the impacts of urbanization or fire are location specific. If we do not communicate these dependencies we risk over-simplifying and eroding scientific credibility when observed effects don't match simple generalizations. On the other hand excessive detail can overwhelm and disengage audiences. So how do we help different communities public, private landowners, other scientists, NGOs, governments to better understand the role of space-time heterogeneity. To address this issue, we present some results from ongoing work that looks at the impact of fuel treatment of forest ecohydrology. This work stem from a collaboration between an ecohydrologic modeling team, social-scientists, a visual artist and compute graphics students. We use a coupled model, validated with field measurements, to show why spatial heterogeneity matters for understanding the impact of fuel treatments on the water cycle for the Sierra

  11. Why Companies Fail? The Boiling Frog Syndrome

    OpenAIRE

    Ozcan, Rasim

    2018-01-01

    Why nations fail? An answer is given by Acemoglu and Robinson (2012) by pointing out the importance of institutions for an economy that leads to innovations for economic growth. Christensen (2012) asks a similar question for a firm and diagnoses why companies fail. In this study, I relate Acemoglu and Robinson (2012) with Christensen (2012) in order to better understand how to make companies more prosperous, more powerful, healthier, and live longer via innovations.

  12. Whi7 is an unstable cell-cycle repressor of the Start transcriptional program.

    Start is the main decision point in eukaryotic cell cycle in which cells commit to a new round of cell division. It involves the irreversible activation of a transcriptional program by G1 CDK-cyclin complexes through the inactivation of Start transcriptional repressors, Whi5 in yeast or Rb in mammals. Here we provide novel keys of how Whi7, a protein related at sequence level to Whi5, represses Start. Whi7 is an unstable protein, degraded by the SCF Grr1 ubiquitin-ligase, whose stability is cell cycle regulated by CDK1 phosphorylation. Importantly, Whi7 associates to G1/S gene promoters in late G1 acting as a repressor of SBF-dependent transcription. Our results demonstrate that Whi7 is a genuine paralog of Whi5. In fact, both proteins collaborate in Start repression bringing to light that yeast cells, as occurs in mammalian cells, rely on the combined action of multiple transcriptional repressors to block Start transition.The commitment of cells to a new cycle of division involves inactivation of the Start transcriptional repressor Whi5. Here the authors show that the sequence related protein Whi7 associates to G1/S gene promoters in late G1 and collaborates with Whi5 in Start repression.

  13. Why the oil companies lost solar

    International Nuclear Information System (INIS)

    Miller, Damian

    2013-01-01

    Solar energy is a growing source of electricity supply. Oil companies including BP and Shell recognized this early on and entered the solar industry when it was still in its relative infancy. These companies invested heavily in vertically integrated solar companies that were at one point among the largest in the world. But neither BP nor Shell was successful, and they both decided to exit the solar market. This stands as a paradox since such companies have the funds, the long-term perspectives, the management systems, the multinational presence and the lobbying clout to potentially succeed in this new energy industry. Why were they not successful, and why did they ultimately exit? This paper uses innovation theory to explore the reasons why large incumbent corporations typically fail to succeed in commercializing disruptive innovations at scale. Evidence from semi-structured interviews and discussions with former employees of BP Solar and Shell Solar confirm the explanatory power of key constructs from innovation theory in accounting for the big oil companies' experience with solar technology. Ultimately, the findings suggest that oil companies would have done better to treat their solar businesses as separate stand-alone entities. - Highlights: • This paper examines why BP and Shell were not successful in solar, and exited. • It finds innovation theory to be very helpful in answering the question. • The evidence from semi-structured interviews, press reports, and archival documentation is in line with innovation theory. • Both the theory and the findings offer a different way forward for future oil and gas entrants

Dialetheism, however, has been criticised as irrational or self-refutating. Therefore the second part of the paper outlines one way to make dialetheism rational assertable. True contradictions turn out to be both believable and assertable. The argument proceeds by setting out basic principles of assertion and denial, and employing bivalent truth value operators.

Based on surveys, interviews and statistical analysis, this study identified that conceptual gaps in contract negotiation, lack of consensus in the agricultural sector regarding the use of financial mechanisms and the sector’s infrequent contact with Colombia’s financial institutions, are the main reasons why a futures contracts market has not emerged.

  13. Why Games Work and the Science of Learning

    Science.gov (United States)

    Murphy, Curtiss

    2012-01-01

    In 2010, the Navy formally added the Damage Control Trainer (DCT) to the recruit training program at Great Lakes, Illinois. Despite the incredibly dense training schedule at the Navy's boot camp, the instructors were willing to set aside two hours of time for recruits to play a game. Why? Because it worked. Even with just one hour of play, research showed that recruits gained a 50-80% improvement in performance that transferred to Battle Stations 21 (B821), the Navy's capstone training event. This paper explores why games makes these kinds of results possible. It argues that the things that are known to improve learning are almost exactly the same reasons why games work: the time-honored laws of learning. It concludes that the traditional gulf between instructional design and game design is really an issue of perspective, rather than fundamentals.

  14. Why Astronomy Should BE Part of the School Curriculum

    Science.gov (United States)

    Percy, John

    Why is astronomy useful? Why should it be supported by taxpayers? Why should it be part of the school curriculum? In this paper I will list 20 reasons. They include: cultural historical and philosophical reasons; practical technological and scientific reasons; environmental aesthetic and emotional reasons; and pedagogical reasons. Astronomy can attract young people to science and technology. It can promote public awareness understanding and appreciation of science. It can be done as an inexpensive hobby; ""the stars belong to everyone"". Finally: I will connect the 20 reasons to the expectations of the modern school curriculum: knowledge skills applications and attitudes. In the context of the science curriculum this includes science technology society and environment.

  15. Constitutive expression of ftsZ overrides the whi developmental genes to initiate sporulation of Streptomyces coelicolor.

    Science.gov (United States)

    Willemse, Joost; Mommaas, A Mieke; van Wezel, Gilles P

    2012-03-01

    The filamentous soil bacteria Streptomyces undergo a highly complex developmental programme. Before streptomycetes commit themselves to sporulation, distinct morphological checkpoints are passed in the aerial hyphae that are subject to multi-level control by the whi sporulation genes. Here we show that whi-independent expression of FtsZ restores sporulation to the early sporulation mutants whiA, whiB, whiG, whiH, whiI and whiJ. Viability, stress resistance and high-resolution electron microscopy underlined that viable spores were formed. However, spores from sporulation-restored whiA and whiG mutants showed defects in DNA segregation/condensation, while spores from the complemented whiB mutant had increased stress sensitivity, perhaps as a result of changes in the spore sheath. In contrast to the whi mutants, normal sporulation of ssgB null mutants-which fail to properly localise FtsZ-could not be restored by enhancing FtsZ protein levels, forming spore-like bodies that lack spore walls. Our data strongly suggest that the whi genes control a decisive event towards sporulation of streptomycetes, namely the correct timing of developmental ftsZ transcription. The biological significance may be to ensure that sporulation-specific cell division will only start once sufficient aerial mycelium biomass has been generated. Our data shed new light on the longstanding question as to how whi genes control sporulation, which has intrigued scientists for four decades.

  19. Why diversity means more than just gender

    CERN Multimedia

    2016-01-01

    In this, my first message to the personnel, I’d like to focus on diversity. In all my time representing Switzerland in Council bodies, and looking at CERN from the outside, I was always impressed by the way in which the Organization deals with this issue. Fairness is intrinsic to a place like CERN, as it is to science, and I think that’s the key, because fairness is at the heart of nurturing diversity.   Whether we’re talking about the biosphere, what we eat or the place where we work, diversity is key. But in all these cases, nurturing diversity requires effort, and that’s as true for CERN as it is for anywhere else. That’s why we have a diversity office to help us. It’s why we have policies that promote diversity, and it’s one of the reasons why we have a code of conduct to guide us in our working relationships. People often equate diversity with visible aspects such as gender and ethnicity, but there’s a l...

  20. The why of things: causality in science, medicine, and life

    CERN Document Server

    Rabins, Peter V.

    2013-01-01

    Why was there a meltdown at the Fukushima power plant? Why do some people get cancer and not others? Why is global warming happening? Why does one person get depressed in the face of life's vicissitudes while another finds resilience? Questions like these -- questions of causality -- form the basis of modern scientific inquiry, posing profound intellectual and methodological challenges for researchers in the physical, natural, biomedical, and social sciences. In this groundbreaking book, noted psychiatrist and author Peter Rabins offers a conceptual framework for analyzing daunting questions of causality. Navigating a lively intellectual voyage between the shoals of strict reductionism and relativism, Rabins maps a three-facet model of causality and applies it to a variety of questions in science, medicine, economics, and more. Throughout this book, Rabins situates his argument within relevant scientific contexts, such as quantum mechanics, cybernetics, chaos theory, and epigenetics. A renowned communicator o...

  1. Role of microRNAs in senescence and its contribution to peripheral neuropathy in the arsenic exposed population of West Bengal, India.

    Chatterjee, Debmita; Bandyopadhyay, Apurba; Sarma, Nilendu; Basu, Santanu; Roychowdhury, Tarit; Roy, Sib Sankar; Giri, Ashok K

    2018-02-01

    Arsenic induced senescence (AIS) has been identified in the population of West Bengal, India very recently. Also there is a high incidence of arsenic induced peripheral neuropathy (PN) throughout India. However, the epigenetic regulation of AIS and its contribution in arsenic induced PN remains unexplored. We recruited seventy two arsenic exposed and forty unexposed individuals from West Bengal to evaluate the role of senescence associated miRNAs (SA-miRs) in AIS and their involvement if any, in PN. The downstream molecules of the miRNA associated with the disease outcome, was also checked by immuoblotting. In vitro studies were conducted with HEK 293 cells and sodium arsenite exposure. Our results show that all the SA-miRs were upregulated in comparison to unexposed controls. miR-29a was the most significantly altered, highest expression being in the arsenic exposed group with PN, suggesting its association with the occurrence of PN. We looked for the expression of peripheral myelin protein 22 (PMP22), a specific target of miR-29a associated with myelination and found that both in vitro and in vivo results showed over-expression of the protein. Since this was quite contrary to miRNA regulation, we checked for intermediate players β-catenin and GSK-3β upon arsenic exposure which affects PMP22 expression. We found that β-catenin was upregulated in vitro and was also highest in the arsenic exposed group with PN while GSK-3β followed the reverse pattern. Our findings suggest that arsenic exposure alters the expression of SA-miRs and the mir-29a/beta catenin/PMP22 axis might be responsible for arsenic induced PN. Copyright © 2017.

    Full Text Available Reasons for copy-pasting someone else’s works has attracted attention from many sides that copy-pasting activities, or more popular with term plagiarism, have been considered as a threat for academic life. It also happens at the case of muslim students, in which Islam teaches the students to be honest and not to steal from others. For understanding why it happens, this exploration is conducted. The students of English Department of IAIN Syekh Nurjati Cirebon have to write many of their assignments in English. The result of my observations, the quality of the students’ writing is not good enough. One of the cases found is the copy-paste works, or plagiarism. Using interviews instrument, I try to figure out why students of English Department of IAIN Syekh Nurjati Cirebon. There are at least three reasons behind why students act plagiarism; ignorance on the quotation and citation rules, poor writing skills, and the need of instant writing result. This paper tries to explore these reasons. Keywords: copy-paste, plagiarism, writing in English

    Matta, Nadim F; Ashkenas, Ronald N

    2003-09-01

    Big projects fail at an astonishing rate--more than half the time, by some estimates. It's not hard to understand why. Complicated long-term projects are customarily developed by a series of teams working along parallel tracks. If managers fail to anticipate everything that might fall through the cracks, those tracks will not converge successfully at the end to reach the goal. Take a companywide CRM project. Traditionally, one team might analyze customers, another select the software, a third develop training programs, and so forth. When the project's finally complete, though, it may turn out that the salespeople won't enter in the requisite data because they don't understand why they need to. This very problem has, in fact, derailed many CRM programs at major organizations. There is a way to uncover unanticipated problems while the project is still in development. The key is to inject into the overall plan a series of miniprojects, or "rapid-results initiatives," which each have as their goal a miniature version of the overall goal. In the CRM project, a single team might be charged with increasing the revenues of one sales group in one region by 25% within four months. To reach that goal, team members would have to draw on the work of all the parallel teams. But in just four months, they would discover the salespeople's resistance and probably other unforeseen issues, such as, perhaps, the need to divvy up commissions for joint-selling efforts. The World Bank has used rapid-results initiatives to great effect to keep a sweeping 16-year project on track and deliver visible results years ahead of schedule. In taking an in-depth look at this project, and others, the authors show why this approach is so effective and how the initiatives are managed in conjunction with more traditional project activities.

  16. Why Cash "Doesn't" Motivate...

    2011-01-01

    If money is the root of all evil, is it also the root of all motivation? When talking about workplace performance and training, the experts' consensus is a resounding "No." This article discusses why cash doesn't motivate everyone all the time when it comes to workplace performance and training and takes a look at what does.

  17. What technologies do people engage with while driving and why?

    Science.gov (United States)

    Parnell, Katie J; Stanton, Neville A; Plant, Katherine L

    2018-02-01

    This paper presents the findings of a semi-structured interview study that was conducted to identify drivers' self-reported likelihood of engaging with technologies that are now commonly found in modern automobiles. Previous research has focused on the effect these technological tasks have on driving performance, but there has been less focus on how, why and when drivers choose to engage with them. As distraction remains a significant contributor to road accidents, an understanding of why it occurs will give important insights into how it can be prevented. A semi-structured interview schedule was developed to allow drivers to discuss the factors that influence their decision to engage with a variety of different technologies. The methodology facilitated both quantitative ratings of the drivers' likelihood of engaging in a variety of tasks and qualitative insights into why. Age and gender had some influence on the propensity to engage, in line with other findings in the literature, as did road type and task type. The reasons drivers gave for why they engage with potentially distracting tasks inform recommendations for preventing distraction related accidents from the increasingly prevalent sources of technologies available to drivers.

  3. Why do very unattractive workers earn so much?

    Science.gov (United States)

    Kanazawa, Satoshi; Hu, Shihao; Larere, Adrien

    2018-05-01

    Kanazawa and Still (2018) showed that very unattractive workers earned more than unattractive workers, sometimes more than average-looking or attractive workers, because they had higher levels of intelligence and education, but they did not explain why very unattractive workers had higher intelligence and education. There are both theoretical and empirical reasons to expect that some intelligent men may prefer to marry very unattractive women. The analysis of the National Longitudinal Study of Adolescent Health (Add Health) shows that very unattractive women were significantly more likely to be married at Age 29 than unattractive or average-looking women, and their spouses or partners earned significantly more than those of unattractive or average-looking women. If intelligent men have historically preferred to marry very unattractive women generation after generation, then, because both general intelligence and physical attractiveness are highly heritable, this can explain why very unattractive workers are more intelligent and achieve higher education, thereby earning more. It can also explain why the positive correlation between intelligence and physical attractiveness is not larger despite assortative mating of intelligent men of higher status and physically attractive women over many generations.

  4. Overexpression of mtDNA-associated AtWhy2 compromises mitochondrial function

    Directory of Open Access Journals (Sweden)

    Abou-Rached Charbel

    2008-04-01

    Full Text Available Abstract Background StWhy1, a member of the plant-specific Whirly single-stranded DNA-binding protein family, was first characterized as a transcription factor involved in the activation of the nuclear PR-10a gene following defense-related stress in potato. In Arabidopsis thaliana, Whirlies have recently been shown to be primarily localized in organelles. Two representatives of the family, AtWhy1 and AtWhy3 are imported into plastids while AtWhy2 localizes to mitochondria. Their function in organelles is currently unknown. Results To understand the role of mitochondrial Whirlies in higher plants, we produced A. thaliana lines with altered expression of the atwhy2 gene. Organellar DNA immunoprecipitation experiments demonstrated that AtWhy2 binds to mitochondrial DNA. Overexpression of atwhy2 in plants perturbs mitochondrial function by causing a diminution in transcript levels and mtDNA content which translates into a low activity level of respiratory chain complexes containing mtDNA-encoded subunits. This lowered activity of mitochondria yielded plants that were reduced in size and had distorted leaves that exhibited accelerated senescence. Overexpression of atwhy2 also led to early accumulation of senescence marker transcripts in mature leaves. Inactivation of the atwhy2 gene did not affect plant development and had no detectable effect on mitochondrial morphology, activity of respiratory chain complexes, transcription or the amount of mtDNA present. This lack of phenotype upon abrogation of atwhy2 expression suggests the presence of functional homologues of the Whirlies or the activation of compensating mechanisms in mitochondria. Conclusion AtWhy2 is associated with mtDNA and its overexpression results in the production of dysfunctional mitochondria. This report constitutes the first evidence of a function for the Whirlies in organelles. We propose that they could play a role in the regulation of the gene expression machinery of organelles.

  5. Why science does not disprove God

    CERN Document Server

    Aczel, Amir D

    2014-01-01

    The renowned science writer, mathematician, and bestselling author of Fermat's Last Theorem masterfully refutes the overreaching claims the "New Atheists," providing millions of educated believers with a clear, engaging explanation of what science really says, how there's still much space for the Divine in the universe, and why faith in both God and empirical science are not mutually exclusive. A highly publicized coterie of scientists and thinkers, including Richard Dawkins, the late Christopher Hitchens, and Lawrence Krauss, have vehemently contended that breakthroughs in modern science have disproven the existence of God, asserting that we must accept that the creation of the universe came out of nothing, that religion is evil, that evolution fully explains the dazzling complexity of life, and more. In this much-needed book, science journalist Amir Aczel profoundly disagrees and conclusively demonstrates that science has not, as yet, provided any definitive proof refuting the existence of God.

  7. Improving global health: counting reasons why.

    Science.gov (United States)

    Selgelid, Michael J

    2008-08-01

    This paper examines cumulative ethical and self-interested reasons why wealthy developed nations should be motivated to do more to improve health care in developing countries. Egalitarian and human rights reasons why wealthy nations should do more to improve global health are that doing so would (1) promote equality of opportunity (2) improve the situation of the worst-off, (3) promote respect of the human right to have one's most basic needs met, and (4) reduce undeserved inequalities in well-being. Utilitarian reasons for improving global health are that this would (5) promote the greater good of humankind, and (6) achieve enormous benefits while requiring only small sacrifices. Libertarian reasons are that this would (7) amend historical injustices and (8) meet the obligation to amend injustices that developed world countries have contributed to. Self-interested reasons why wealthy nations should do more to improve global health are that doing so would (9) reduce the threat of infectious diseases to developed countries, (10) promote developed countries' economic interests, and (11) promote global security. All of these reasons count, and together they add up to make an overwhelmingly powerful case for change. Those opposed to wealthy government funding of developing world health improvement would most likely appeal, implicitly or explicitly to the idea that coercive taxation for redistributive purposes would violate the right of an individual to keep his hard-earned income. The idea that this reason not to improve global health should outweigh the combination of rights and values embodied in the eleven reasons enumerated above, however is implausibly extreme, morally repugnant and perhaps imprudent.

  13. Why Nature Chose Selenium.

    Science.gov (United States)

    Reich, Hans J; Hondal, Robert J

    2016-04-15

    The authors were asked by the Editors of ACS Chemical Biology to write an article titled "Why Nature Chose Selenium" for the occasion of the upcoming bicentennial of the discovery of selenium by the Swedish chemist Jöns Jacob Berzelius in 1817 and styled after the famous work of Frank Westheimer on the biological chemistry of phosphate [Westheimer, F. H. (1987) Why Nature Chose Phosphates, Science 235, 1173-1178]. This work gives a history of the important discoveries of the biological processes that selenium participates in, and a point-by-point comparison of the chemistry of selenium with the atom it replaces in biology, sulfur. This analysis shows that redox chemistry is the largest chemical difference between the two chalcogens. This difference is very large for both one-electron and two-electron redox reactions. Much of this difference is due to the inability of selenium to form π bonds of all types. The outer valence electrons of selenium are also more loosely held than those of sulfur. As a result, selenium is a better nucleophile and will react with reactive oxygen species faster than sulfur, but the resulting lack of π-bond character in the Se-O bond means that the Se-oxide can be much more readily reduced in comparison to S-oxides. The combination of these properties means that replacement of sulfur with selenium in nature results in a selenium-containing biomolecule that resists permanent oxidation. Multiple examples of this gain of function behavior from the literature are discussed.

In Why Greatness Cannot Be Planned, Stanley and Lehman begin with a surprising scientific discovery in artificial intelligence that leads ultimately to the conclusion that the objective obsession has gone too far. They make the case that great achievement can't be bottled up int

  16. Why three generations?

    Directory of Open Access Journals (Sweden)

    Masahiro Ibe

    2016-07-01

    Full Text Available We discuss an anthropic explanation of why there exist three generations of fermions. If one assumes that the right-handed neutrino sector is responsible for both the matter–antimatter asymmetry and the dark matter, then anthropic selection favors three or more families of fermions. For successful leptogenesis, at least two right-handed neutrinos are needed, while the third right-handed neutrino is invoked to play the role of dark matter. The number of the right-handed neutrinos is tied to the number of generations by the anomaly constraints of the U(1B−L gauge symmetry. Combining anthropic arguments with observational constraints, we obtain predictions for the X-ray observations, as well as for neutrinoless double-beta decay.

    Four 'uses and gratifications' studies investigated peoples' reasons for listening to music (Study 1); and whether these reasons differ significantly from those associated with other leisure activities (Study 2). In Study 3, an open-ended, qualitative research design was used to investigate why people listen to music. In Study 4, a cross-sectional design was used to investigate the possibility that people of different ages might listen to music for different reasons. Findings showed that there are a number of reasons why participants listen to music, comparison of which indicated that participants listen to music primarily to manage/regulate their moods. Comparison with other leisure activities indicated that for the most part, listening to music was rated better than other leisure activities at serving an individual's different needs. This versatility may explain why music is so important to people. Evidence was also found to suggest that the reasons for listening to music may change as people grow older. ©2010 The British Psychological Society.

    Why is gravity weak? Gravity is plagued with this and many other questions. After decades of exhausting work we do not have a clear answer. In view of this fact it will be shown in the following pages that there are reasons for thinking that gravity is just a composite force consisting of the long-range manifestations of short range nuclear forces that are too tiny to be measured at illuminated or long ranges by particle colliders. This is consistent with Einstein's proposal in 1919

    Science.gov (United States)

    Varnum, Michael E W; Grossmann, Igor

    2017-11-01

    More than half a century of cross-cultural research has demonstrated group-level differences in psychological and behavioral phenomena, from values to attention to neural responses. However, cultures are not static, with several specific changes documented for cultural products, practices, and values. How and why do societies change? Here we juxtapose theory and insights from cultural evolution and social ecology. Evolutionary approaches enable an understanding of the how of cultural change, suggesting transmission mechanisms by which the contents of culture may change. Ecological approaches provide insights into the why of cultural change: They identify specific environmental pressures, which evoke shifts in psychology and thereby enable greater precision in predictions of specific cultural changes based on changes in ecological conditions. Complementary insights from the ecological and cultural evolutionary approaches can jointly clarify the process by which cultures change. We end by discussing the relevance of cultural change research for the contemporary societal shifts and by highlighting several critical challenges and future directions for the emerging field of cross-temporal research on culture and psychology.

  14. Why withdrawal from the European Union is undemocratic

    DEFF Research Database (Denmark)

    Olsen, Tore Vincents; Rostbøll, Christian F.

    2017-01-01

    The Lisbon Treaty from 2009 introduced the possibility for individual member states to withdraw from the European Union (EU) on the basis of a unilateral decision. In June 2016 the UK decided to leave the EU invoking article 50 of the treaty. But is withdrawal democratically legitimate? In fact......, the all affected principle suggests that it is undemocratic for subunits to leave larger political units when it adversely affects other citizens without including them in the decision. However, it is unclear what the currency of this affectedness is and, hence, why withdrawal would be undemocratic. We...... argue that it is the effect of withdrawal on the status of citizens as free and equal that is decisive and that explains why unilateral withdrawal of subunits from larger units is democratically illegitimate. Moreover, on the ‘all affected status principle’ that we develop, even multilaterally agreed...

  15. A Theoretical Analysis of Why Hybrid Ensembles Work

    Directory of Open Access Journals (Sweden)

    Kuo-Wei Hsu

    2017-01-01

    Full Text Available Inspired by the group decision making process, ensembles or combinations of classifiers have been found favorable in a wide variety of application domains. Some researchers propose to use the mixture of two different types of classification algorithms to create a hybrid ensemble. Why does such an ensemble work? The question remains. Following the concept of diversity, which is one of the fundamental elements of the success of ensembles, we conduct a theoretical analysis of why hybrid ensembles work, connecting using different algorithms to accuracy gain. We also conduct experiments on classification performance of hybrid ensembles of classifiers created by decision tree and naïve Bayes classification algorithms, each of which is a top data mining algorithm and often used to create non-hybrid ensembles. Therefore, through this paper, we provide a complement to the theoretical foundation of creating and using hybrid ensembles.

  18. How big is big and how small is small the sizes of everything and why

    CERN Document Server

    Smith, Timothy Paul

    2013-01-01

    This book is about how big is the universe and how small are quarks, and what are the sizes of dozens of things between these two extremes. It describes the sizes of atoms and planets, quarks and galaxies, cells and sequoias. It is a romp through forty-five orders of magnitude from the smallest sub-nuclear particles we have measured, to the edge of the observed universe. It also looks at time, from the epic age of the cosmos to the fleeting lifetimes of ethereal particles. It is a narrative that trips its way from stellar magnitudes to the clocks on GPS satellites, from the nearly logarithmic scales of a piano keyboard through a system of numbers invented by Archimedes and on to the measurement of the size of an atom. Why do some things happen at certain scales? Why are cells a hundred thousandths of a meter across? Why are stars never smaller than about 100 million meters in diameter? Why are trees limited to about 120 meters in height? Why are planets spherical, but asteroids not? Often the size of an objec...

In the context of advanced optical and tracking technologies that render animals permanently visible, the possibility of not-seeing emerges as a progressive modality of relation to animals that takes seriously the notion of animal privacy and the exposed animal’s resistance to the human gaze.

    The relationship between sleep and migraine headaches is complex. Changes in sleep patterns can trigger migraine attacks, and sleep disorders may be associated with increased migraine frequency. Furthermore, migraine patients and their doctors very consistently report that sleep relieves already established migraine attacks. Herein we will try to answer the question, "Why does sleep stop migraine?" Since evidence for this relationship is largely based on empirical clinical observation, we will not provide a clinical review of the association. Instead, we will focus on the pathophysiology of migraine attacks and its intersections with sleep biology.

    DEFF Research Database (Denmark)

    2001-01-01

    According to economists solving environmental problems is simple. Politicians should simply impose a uniform tax on harmful emissions. However, the actual design of such green taxation shows that politicians do not follow their advice. CO2 taxation in OECD, for example, is highly differentiated...... and much in favour of industry. In fact, CO2 tax rates for industry are, on average, six times lower than those for households. We argue that the reason for this tax differentiation is that industry, in contrast to households, has a strong capability to lobby. Therefore, green taxation is effectively...... blocked and the desired environmental results are not being achieved. Why then is green taxation persistently applied in relation to industry? We argue that strong fiscal incentives drive this policy choice at the expense of environmental concerns because it allows environmental bureaucracies to budget-maximize....

  10. Why partition nuclear waste

    International Nuclear Information System (INIS)

    Cohen, J.J.

    1976-01-01

    A cursory review of literature dealing with various separatory processes involved in the handling of high-level liquid nuclear waste discloses that, for the most part, discussion centers on separation procedures and methodology for handling the resulting fractions, particularly the actinide wastes. There appears to be relatively little discussion on the incentives or motivations for performing these separations in the first place. Discussion is often limited to the assumption that we must separate out ''long-term'' from our ''short-term'' management problems. This paper deals with that assumption and devotes primary attention to the question of ''why partition waste'' rather than the question of ''how to partition waste'' or ''what to do with the segregated waste.''

    Hoffman, Moshe; Yoeli, Erez; Nowak, Martin A.

    2015-01-01

    Evolutionary game theory typically focuses on actions but ignores motives. Here, we introduce a model that takes into account the motive behind the action. A crucial question is why do we trust people more who cooperate without calculating the costs? We propose a game theory model to explain this phenomenon. One player has the option to “look” at the costs of cooperation, and the other player chooses whether to continue the interaction. If it is occasionally very costly for player 1 to cooperate, but defection is harmful for player 2, then cooperation without looking is a subgame perfect equilibrium. This behavior also emerges in population-based processes of learning or evolution. Our theory illuminates a number of key phenomena of human interactions: authentic altruism, why people cooperate intuitively, one-shot cooperation, why friends do not keep track of favors, why we admire principled people, Kant’s second formulation of the Categorical Imperative, taboos, and love.

    2009-10-01

    Full Text Available Abstract After any therapy, when symptoms improve, healthcare providers (and patients are tempted to award credit to treatment. Over time, a particular treatment can seem so undeniably helpful that scientific verification of efficacy is judged an inconvenient waste of time and resources. Unfortunately, practitioners' accumulated, day-to-day, informal impressions of diagnostic reliability and clinical efficacy are of limited value. To help clarify why even treatments entirely lacking in direct effect can seem helpful, I will explain why real signs and symptoms often improve, independent of treatment. Then, I will detail quirks of human perception, interpretation, and memory that often make symptoms seem improved, when they are not. I conclude that healthcare will grow to full potential only when judgments of clinical efficacy routinely are based in properly scientific, placebo-controlled, outcome analysis.

The model explains why relative female wages rose almost unabated from 1890 to the early-1990s in the United States (with the exception of about 1940-1980), and why this relative wage growth tapered off since 1993. In addition to the US, the paper presents evidence from nine other countr...

  5. Why investors shy away from coal

    International Nuclear Information System (INIS)

    Roling, D.A.

    1994-01-01

    Why do investors shy away from coal? This may sound like a strange question given the change in ownership of many major coal companies in recent years, but the ongoing consolidation within the coal industry is quite different from any actual new investment in the industry. To begin to understand why, one must return to the early '70s, a time of low-cost, abundant energy. The price of oil was about $2-4/bbl until 1973. The price of natural gas was about 60 cents/M ft 3 , and coal was approximately $7/st. This, however, was before the first Organization of the Petroleum Exporting Countries (OPEC) shock. The price of coal declined throughout the 1980s, and continues its downward path in some markets. Many coal investments have not achieved their expected return, such as the case of a 1M st/yr mine in West Virginia, which was developed in the early '80s only to be put immediately on a care-and-maintenance basis, where it languished until it was sold in 1990. Other mines, such as the large open-pit mines in the Powder River Basin in Wyoming, never reached their targeted production rates. Some of these large mines had equipment that remained in crates for years, only later to be sold at a loss. The extent of losses on investments in coal mines is discussed

  6. “Why Nations Fail” to Develop

    Directory of Open Access Journals (Sweden)

    Victor E. Dike

    2015-10-01

    Full Text Available This article focuses on the forces that prevent nations from developing politically, socially, and economically or why some of them have failed to achieve their purpose. It draws profusely from two inspiring books: Why Nations Fail and Leading From the Emerging Future to explore as to whether or not the political leaders of Nigeria can learn any lesson from the seminal work. The books concentrate on practical approaches that empower political leaders to shift their mind-sets to enable them to transform their extant extractive political and economic institutions that hinder national development. Unlike previous studies on leadership and development in Nigeria, which have observed that the system has been rendered unproductive by poor leadership, this article argues that the problem with Nigeria is that the political leaders have failed to shift their engrained mind-sets from “ego-system awareness to eco-system reality” to enable them to build and maintain effective institutions and infrastructure that drive the economy and develop the nations. It also argues that discussion about the leaders’ mind-set and national development deserves a different approach to transform the nation’s ossified institutions into innovative and creative ones. This will encourage the leaders to collectively shift their mental models to design and implement growth policies that will fit into the 21st-century economy and empower them to lead from the emerging future.

    Why are blue-collar blacks less likely to help jobseekers than jobholders from other ethnoracial groups or even than more affluent blacks? Drawing from in-depth, semi-structured interviews with 97 black and Latino workers at one large, public sector employer, we find that blue-collar black workers both helped less proactively and rejected more requests for assistance than did blue-collar Latino and white-collar black workers. We attribute blue-collar blacks’ more passive engagement to their...

    Paulson, Steve; Albert, David; Holt, Jim; Turok, Neil

    2015-12-01

    Perhaps the greatest mystery is why the universe exists in the first place. How is it possible for something to emerge from nothing, or has a universe in some form always existed? This question of origins-both of the universe as a whole and of the fundamental laws of physics-raises profound scientific, philosophical, and religious questions, culminating in the most basic existential question of all: Why are we here? Discussion of this and related questions is presented in this paper. © 2015 New York Academy of Sciences.

  20. Energy, entropy, environment: Why is protection of the environment objectively difficult?

    Energy Technology Data Exchange (ETDEWEB)

    Rebane, Karl K [Institute of Physics, Tartu (Estonia)

    1995-05-01

    Evolution and man`s history indicate that the winners are the species and societies that act faster and consume more high-quality energy and materials: in other words, those which cause more pollution and faster growth of entropy. This could be the reason why protection of the environment is objectively difficult and, in particular, why it is almost impossible to considerably reduce man`s consumption of energy and materials in a world of competition. To escape this fatal evolutionary outcome, fundamentally new thinking is needed, thinking which takes the survival of mankind as the primary value. The role of religion in solving this tremendously difficult task should not be neglected

  6. Evolutionary explanations in medical and health profession courses: are you answering your students' "why" questions?

    Directory of Open Access Journals (Sweden)

    Malyango Avelin A

    2005-05-01

    Full Text Available Abstract Background Medical and pre-professional health students ask questions about human health that can be answered in two ways, by giving proximate and evolutionary explanations. Proximate explanations, most common in textbooks and classes, describe the immediate scientifically known biological mechanisms of anatomical characteristics or physiological processes. These explanations are necessary but insufficient. They can be complemented with evolutionary explanations that describe the evolutionary processes and principles that have resulted in human biology we study today. The main goal of the science of Darwinian Medicine is to investigate human disease, disorders, and medical complications from an evolutionary perspective. Discussion This paper contrasts the differences between these two types of explanations by describing principles of natural selection that underlie medical questions. Thus, why is human birth complicated? Why does sickle cell anemia exist? Why do we show symptoms like fever, diarrhea, and coughing when we have infection? Why do we suffer from ubiquitous age-related diseases like arteriosclerosis, Alzheimer's and others? Why are chronic diseases like type II diabetes and obesity so prevalent in modern society? Why hasn't natural selection eliminated the genes that cause common genetic diseases like hemochromatosis, cystic fibrosis, Tay sachs, PKU and others? Summary In giving students evolutionary explanations professors should underscore principles of natural selection, since these can be generalized for the analysis of many medical questions. From a research perspective, natural selection seems central to leading hypotheses of obesity and type II diabetes and might very well explain the occurrence of certain common genetic diseases like cystic fibrosis, hemochromatosis, Tay sachs, Fragile X syndrome, G6PD and others because of their compensating advantages. Furthermore, armed with evolutionary explanations, health care

  7. Why does E=mc2 ? And why should we care?

    CERN Document Server

    Cox, Brian

    2009-01-01

    Professor Brian Cox and Professor Jeff Forshaw go on a journey to the frontier of 21st century science to consider the real meaning behind the iconic sequence of symbols that make up Einstein’s most famous equation, E=mc2. Breaking down the symbols themselves, they pose a series of questions: What is energy? What is mass? What has the speed of light got to do with energy and mass? In answering these questions, they take us to the site of one of the largest scientific experiments ever conducted. Lying beneath the city of Geneva, straddling the Franco-Swiss boarder, is a 27 km particle accelerator, known as the Large Hadron Collider. Using this gigantic machine-which can recreate conditions in the early Universe fractions of a second after the Big Bang-Cox and Forshaw will describe the current theory behind the origin of mass. Alongside questions of energy and mass, they will consider the third, and perhaps, most intriguing element of the equation: 'c' - or the speed of light. Why is it that the speed of ligh...

  12. [Enteral alimentation at home: why PEG now?].

    Science.gov (United States)

    Suzuki, Y; Hanyu, N; Kashiwagi, H; Kubo, T; Aoki, T

    1996-12-01

    The history of percutaneous endoscopic gastrostomy (PEG) is relatively short. In 1980, a report entitled "Gastrostomy without laparotomy: A percutaneous endoscopic technique" by Ponsky and Gaudere was first published in the Journal of Pediatric Surgery. Thereafter, PEG soon saw widespread use in Western countries because of its clinical efficacy and economy. It has been performed in about 170,000 cases annually in the US. In contrast, its spread in Japan has been extremely slow: only about 10,000 cases have undergone this procedure annually, and this number accounted for less than 5% of patients receiving enteral alimentation. The reason why PEG has not spread may be the medical insurance system in Japan and the local distaste for operation scarring. However, in consideration of the unprecedented ageing of society that is surely coming in the near future, the role of PEG in Japan must be reexamined. In this report, we presented the methodology of enteral alimentation at home by means of PEG, giving special consideration to: (1) "What points are improved by using enteral alimentation at home by means of PEG in various diseases; (2) dysphagia due to cerebral angiopathy; (3) terminal cancer; (4) otolaryngological diseases; and (5) Crohn disease. We also discussed "Why PEG is important now?" in performing enteral alimentation at home.

  13. Abstract "why" Thoughts About Success Lead to Greater Positive Generalization in Sport Participants.

    Science.gov (United States)

    Van Lier, Jens; Moulds, Michelle L; Raes, Filip

    2015-01-01

    Generalizing from a single failure or success to future performances and their self-concept could have an important impact on sport participants. This study examined the impact of the way sport participants think about success on positive generalization. Sport participants (N = 222) completed an online experimental study in which they were induced to think about meanings, causes and implications (i.e., abstract-"why"-thinking) or about more perceptual concrete aspects of their performance (i.e., concrete-"how"-thinking). We hypothesized that abstract-"why"-thinking would lead to greater positive generalization and that this effect would be moderated by self-esteem. Our results supported our hypothesis that abstract thinking increased positive generalization, and this effect was more clearly visible in sport participants with higher self-esteem. These results suggest that retrospective thinking about the "why" of a good performance may benefit athletes in the long run because they generalize the outcome to future performances and their self-concept which may boost their motivation and consequently their performance.

  14. Why neutron stars have three hairs

    Stein, Leo; Yagi, Kent; Pappas, George; Yunes, Nicolas; Apostolatos, Theocharis

    2015-04-01

    Neutron stars have recently been found to enjoy a certain `baldness' in their multipolar structure which is independent of the equation of state (EoS) of dense nuclear matter. This is reminiscent of the black hole no-hair relations, and in stark contrast to regular stars. Why is this? Is it because realistic EoSs are sufficiently similar, or because GR effects are especially important, or because the nuclear matter is `cold'? We explore the physics behind these and more hypotheses, and give a convincing explanation for the true origin of the three-hair relations.

  1. Why prove it again? alternative proofs in mathematical practice

    CERN Document Server

    Dawson, Jr , John W

    2015-01-01

    This monograph considers several well-known mathematical theorems and asks the question, “Why prove it again?” while examining alternative proofs.   It  explores the different rationales mathematicians may have for pursuing and presenting new proofs of previously established results, as well as how they judge whether two proofs of a given result are different.  While a number of books have examined alternative proofs of individual theorems, this is the first that presents comparative case studies of other methods for a variety of different theorems. The author begins by laying out the criteria for distinguishing among proofs and enumerates reasons why new proofs have, for so long, played a prominent role in mathematical practice.  He then outlines various purposes that alternative proofs may serve.  Each chapter that follows provides a detailed case study of alternative proofs for particular theorems, including the Pythagorean Theorem, the Fundamental Theorem of Arithmetic, Desargues’ Theorem, the...

  2. Hotel location decision-making in the Kumasi Metropolis of Ghana: with whom and why?

    Directory of Open Access Journals (Sweden)

    Issahaku Adam

    2012-01-01

    Full Text Available Knowledge on the people involved in hotel location decision-making and why they are involved is key to destination planning and development. Insights gained into this subject are useful to future destination planners. Despite its importance, the subject of whom to involve in the hotel location decision and why they should be involved, has received limited research interest in Ghana. This study identifies the people involved in hotel location decisions and assesses the reasons why they are involved. Data was collected from hotel owners in the Kumasi Metropolis and analysed with the chi-square test of independence. Extended family members were mostly involved in the hotel location decisions and for mainly personal reasons. It was concluded that hotel owners in the Kumasi Metropolis involve their family members in the location choice for non-professional reasons.

    While most young people regularly consume and produce social media content, many schools focus on what students should not do with these technologies rather than address what students and teachers can do. The authors share ways that some educators leverage social media to enhance the who, when, where, why, how, and what of educational processes.

  8. Life or Death: Anxiety About the Urban in 1950s Egyptian Cinema

    OpenAIRE

    2015-01-01

    Life or Death (Haya aw mawt) is a classic of Egyptian cinema, widely interpreted retrospectively by scholars as an ode to progress, modernity, the nation, and the chief emblem of such, the burgeoning city. Indeed, the film was included in the list of ‘the most important 100 Egyptian films,’ commissioned by the Bibliotheca Alexandrina and assembled by Ahmed el-Hadari, Samir Farid, and Kamal Ramzi in 2006. Released in 1954, the film is associated by critics and scholars with the 1952 Free Offic...

  9. Generalized anxiety disorder and online intelligence: a phenomenological account of why worrying is unhelpful.

    Science.gov (United States)

    Meynen, Gerben

    2011-05-03

    Worrying is the central feature of generalized anxiety disorder (GAD). Many people worry from time to time, but in GAD the worrying is prolonged and difficult to control. Worrying is a specific way of coping with perceived threats and feared situations. Meanwhile, it is not considered to be a helpful coping strategy, and the phenomenological account developed in this paper aims to show why. It builds on several phenomenological notions and in particular on Michael Wheeler's application of these notions to artificial intelligence and the cognitive sciences. Wheeler emphasizes the value of 'online intelligence' as contrasted to 'offline intelligence'. I discuss and apply these concepts with respect to worrying as it occurs in GAD, suggesting that GAD patients overrate the value of detached contemplation (offline intelligence), while underrating their embodied-embedded adaptive skills (online intelligence). I argue that this phenomenological account does not only help explaining why worrying is used as a coping strategy, but also why cognitive behavioral therapy is successful in treating GAD.

  10. Why teach literature and medicine? Answers from three decades.

    Science.gov (United States)

    Jones, Anne Hudson

    2013-12-01

    In this essay, I look back at some of the earliest attempts by the first generation of literature-and-medicine scholars to answer the question: Why teach literature and medicine? Reviewing the development of the field in its early years, I examine statements by practitioners to see whether their answers have held up over time and to consider how the rationales they articulated have expanded or changed in the following years and why. Greater emphasis on literary criticism, narrative ethics, narrative theory, and reflective writing has influenced current work in the field in ways that could not have been foreseen in the 1970s. The extraordinary growth of interest and work in the field nationally and, especially since 1996, internationally has included practitioners in many additional areas such as disability studies, film studies, therapeutic writing, and trauma studies. Along with the emergence of narrative medicine, this diverse community of scholars and practitioners-affiliated more through their use of narrative methodologies than the teaching of literature-makes the perennial challenge of evaluation and assessment even more complicated.

  11. Why still philosophy?: Once again

    Directory of Open Access Journals (Sweden)

    Krstić Predrag

    2007-01-01

    Full Text Available The intention of this paper is to revisit, once again the question asked by Adorno and Habermas and other contemporary thinkers under different headings few decades ago. The author is suggesting that nowadays philosophy requires a final departure from the idea of having single and perennial face, and that this would not only allow, but also enable philosophy to test its various faces freely, that is, without norm or limit set in advance. At the same time, by creating such ′liberal′ climate philosophy would no longer be frightened by the possible answer, and hence would no longer dramatize the very question of ′why still?′. Even if philosophy turns out to be far less than the mission it once bestowed upon itself.

  12. Why Creativity is Sexy: A Review of the Evidence of Sexual Selection for Creative Abilities in Humans

    Directory of Open Access Journals (Sweden)

    Stoyo Karamihalev

    2013-08-01

    Full Text Available Creativity is an essential human trait, yet there is no consensus among scholars as to why our species have developed creative abilities. Most evolutionary explanations rely on the survival value of such abilities, but generally fail to explain why other species have not evolved similar capacities or why so many human products of creativity have little to no practical value. Sexual selection is an evolutionary force which has the potential to shed new light on this investigation by regarding creativity as a fitness indicator that has evolved for the purposes of courtship and mating. The paper at hand reviews the empirical evidence in support of this hypothesis.

  17. Why change habits? Early modern medical innovation between medicalisation and medical culture.

    Science.gov (United States)

    Loetz, Francisca

    2010-01-01

    Based on a discussion of the concept of medicalisation and medical culture in Anglo-American, French-, and German-speaking historiography the paper argues that medical innovation in Europe from the sixteenth to the mid-nineteenth century should be approached in a different way. Instead of asking from the perspective of a too narrow concept of medicalisation why medical innovations were rejected by the population, (medical) historians should analyse medical culture and ask why people should have changed their health and illness behaviour. This conceptual argument is deduced from four empirical examples: the introduction of smallpox vaccination, "medical police," the problem of medical professionalization, and the questions arising around the relations between the healthy/sick and their practitioners.

    Why did the League of Nations ultimately fail to achieve widespread disarmament, its most fundamental goal? This article shows that the failure of the League of Nations had two important dimensions: (1) the failure to provide adequate security guarantees for its members (like an alliance); (2) the failure of this organization to achieve the disarmament goals it set out in the 1920s and 1930s. Thus, it was doomed from the outset to fail, due to built-in institutional contradictions. It can als...

  19. Why the moratorium on human-animal chimera research should not be lifted.

    Science.gov (United States)

    Moy, Alan

    2017-08-01

    The National Institutes of Health (NIH) announced its plans to lift its moratorium on funding research that involves injecting human embryonic stem cells into animal embryos, which would allow for the creation of part-human and part-animal organisms known as chimeras. The NIH allowed only one month to receive public comments in the midst of a presidential election campaign. Lifting the moratorium means that, for the first time, the federal government will begin spending taxpayer dollars on the creation and manipulation of new organisms that would blur the line between humans and animals. Interestingly, this government effort is creating an uncommon coalition between pro-life groups and animal rights activists that oppose this medical research on ethical grounds; the former seeking to ensure the welfare of human embryos and the latter seeking to protect the well-being of animals. Unlike the issue of abortion, this research is complex. Yet, it is important that the pro-life laity and clergy be adequately informed on some of the basic science and ethics that surround this research. To fully understand why this research is unethical and why the NIH is pursuing this particular research, it is important to understand the ethical tenets governing human-subject research and why secular scientists are pursuing this scientific field.

    Science.gov (United States)

    Harata, Ken; Nishiuchi, Takumi; Kubo, Yasuyuki

    2016-06-01

    The hemibiotrophic fungus Colletotrichum orbiculare first establishes a biotrophic infection stage in cucumber (Cucumber sativus) epidermal cells and subsequently transitions to a necrotrophic stage. Here, we found that C. orbiculare established hemibiotrophic infection via C. orbiculare WHI2, a yeast stress regulator homolog, and TOR (target of rapamycin) signaling. Plant defense responses such as callose deposition, H2O2, and antimicrobial proteins were strongly induced by the C. orbiculare whi2Δ mutant, resulting in defective pathogenesis. Expression analysis of biotrophy-specific genes evaluated by the promoter VENUS fusion gene indicated weaker VENUS signal intensity in the whi2Δ mutant, thereby suggesting that C. orbiculare WHI2 plays a key role in regulating biotrophic infection of C. orbiculare. The involvement of CoWHI2 in biotrophic infection was further explored with a DNA microarray. In the Cowhi2Δ mutant, TOR-dependent ribosomal protein-related genes were strikingly upregulated compared with the wild type. Moreover, callose deposition in the host plant after inoculation with the Cowhi2Δ mutant treated with rapamycin, which inhibits TOR activity, was reduced, and the mutant remained biotrophic in contrast to the untreated mutant. Thus, regulation of TOR by Whi2 is apparently crucial to the biotrophic stage of hemibiotrophic infection in C. orbiculare.

    Carter, Lucy M; Kafsack, Björn F C; Llinás, Manuel; Mideo, Nicole; Pollitt, Laura C; Reece, Sarah E

    2013-01-01

    For vector-borne parasites such as malaria, how within- and between-host processes interact to shape transmission is poorly understood. In the host, malaria parasites replicate asexually but for transmission to occur, specialized sexual stages (gametocytes) must be produced. Despite the central role that gametocytes play in disease transmission, explanations of why parasites adjust gametocyte production in response to in-host factors remain controversial. We propose that evolutionary theory developed to explain variation in reproductive effort in multicellular organisms, provides a framework to understand gametocyte investment strategies. We examine why parasites adjust investment in gametocytes according to the impact of changing conditions on their in-host survival. We then outline experiments required to determine whether plasticity in gametocyte investment enables parasites to maintain fitness in a variable environment. Gametocytes are a target for anti-malarial transmission-blocking interventions so understanding plasticity in investment is central to maximizing the success of control measures in the face of parasite evolution.

  6. Why Cafe Worked

    Energy Technology Data Exchange (ETDEWEB)

    Greene, D.L.

    1997-08-01

    The frequently controversial Federal Automotive Fuel Economy Standards (a.k.a. Corporate Average Fuel Economy (CAFE) standards) have in fact been a notable success. This paper attempts to explain why the CAFE standards have been such a successful energy policy. It begins by demonstrating that economic theory does not relegate technology standards to permanent second best status. As a public policy aimed at correcting an externality, regulations can be the key part of a first best public policy response. To be sure, practical problems will arise in implementing either an effluent tax or a regulatory standard. Next, it is argued that in the oligopotistic automotive market a combination of satisfying behavior on the part of consumers and risk aversion on the part of producers makes it very likely that fuel economy standards will be more effective than even a motor fuel tax. This does not mean that gasoline or vehicle use taxes are not important or useful policy tools. Indeed, they are essential if policies are to be economically efficient. It means that taxes will be most effective and efficient if used in conjunction with fuel economy standards.

  8. Why Libertarians Should Reject Positive Rights

    Directory of Open Access Journals (Sweden)

    Joshua Katz

    2009-01-01

    Full Text Available Maloberti, in “Why Libertarians Should Accept Positive Rights” argues that, as normally presented, libertarianism entails anarchism. He argues that libertarians should, therefore, accept a limited form of positive rights, which will allow for the creation of a libertarian government. In this paper, it is argued that the entailment of anarchism is not a problem for libertarianism, and that the form of positive rights endorsed by Maloberti is unfounded, ill-defined, and inconsistent with libertarian notions of individual freedom. It is further argued that Maloberti’s positive rights, as defined in his paper, cannot withstand the analysis prompted by Austrian value theory.

  9. Why Border Enforcement Backfired.

    Science.gov (United States)

    Massey, Douglas S; Durand, Jorge; Pren, Karen A

    2016-03-01

    In this article we undertake a systematic analysis of why border enforcement backfired as a strategy of immigration control in the United States. We argue theoretically that border enforcement emerged as a policy response to a moral panic about the perceived threat of Latino immigration to the United States propounded by self-interested bureaucrats, politicians, and pundits who sought to mobilize political and material resources for their own benefit. The end result was a self-perpetuating cycle of rising enforcement and increased apprehensions that resulted in the militarization of the border in a way that was disconnected from the actual size of the undocumented flow. Using an instrumental variable approach, we show how border militarization affected the behavior of unauthorized migrants and border outcomes to transform undocumented Mexican migration from a circular flow of male workers going to three states into an eleven-million person population of settled families living in 50 states.

    Why the name "Erasmus" for an hospital ? Apart for local circumstances, there are far more obvious reasons for this choice. Erasmus was in close contact with the medical world. Indeed, he suffered all his life from more or less severe diseases and had therefore frequent contacts with doctors. Also, the ideas he was defending stood for the principle of free inquiry before its time. For these various reasons giving the name « Erasmus » to the university clinics of the Free University of Brussels (ULB) was a judicious choise.

  6. Who should know about our genetic makeup and why?

    Takala, T.; Gylling, H. A.

    2000-01-01

    Recent developments in biology have made it possible to acquire more and more precise information concerning our genetic makeup. Although the most far-reaching effects of these developments will probably be felt only after the Human Genome Project has been completed in a few years' time, scientists can even today identify a number of genetic disorders which may cause illness and disease in their carriers. The improved knowledge regarding the human genome will, it is predicted, in the near future make diagnoses more accurate and treatments more effective, and thereby considerably reduce and prevent unnecessary suffering. On the other hand, however, the knowledge can also be, depending on the case, futile, distressing or plainly harmful. This is why we propose to answer in this paper the dual question: who should know about our genetic makeup and why? Through an analysis of prudential, moral and legal grounds for acquiring the information, we conclude that, at least on the levels of law and social policy, practically nobody is either duty-bound to receive or entitled to have that knowledge. Key Words: Genetic testing • genetic screening • law • ethics • duties PMID:10860207

  7. Why older adults may decline offers of post-acute care services: A qualitative descriptive study.

    Sefcik, Justine S; Ritter, Ashley Z; Flores, Emilia J; Nock, Rebecca H; Chase, Jo-Ana D; Bradway, Christine; Potashnik, Sheryl; Bowles, Kathryn H

    The most common post-acute care (PAC) services available to patients after hospital discharge include home care, skilled nursing facilities, nursing homes, inpatient rehabilitation, and hospice. Patients who need PAC and receive services have better outcomes, however almost one-third of those offered services decline. Little research exists on PAC decision-making and why patients may decline services. This qualitative descriptive study explored the responses of thirty older adults to the question: "Can you, from the patient point of view, tell me why someone would not want post hospital care?" Three themes emerged. Participants may decline due to 1) previous negative experiences with PAC, or 2) a preference to be home. Some participants stated, "I'd be there" and would not decline services. Participants also discussed 3) why other patients might decline PAC which included patients' past experiences, lack of understanding/preconceived ideas, and preferences. Clinical implications include assessing patients' knowledge and experience before providing recommendations. Copyright © 2016 Elsevier Inc. All rights reserved.

  10. Why some plant species are rare.

    Wieger Wamelink, G W; Wamelink, G W Weiger; Goedhart, Paul W; Frissel, Joep; Frissel, Josep Y

    2014-01-01

    Biodiversity, including plant species diversity, is threatened worldwide as a result of anthropogenic pressures such as an increase of pollutants and climate change. Rare species in particular are on the verge of becoming extinct. It is still unclear as to why some plant species are rare and others are not. Are they rare due to: intrinsic reasons, dispersal capacity, the effects of management or abiotic circumstances? Habitat preference of rare plant species may play an important role in determining why some species are rare. Based on an extensive data set of soil parameters we investigated if rarity is due to a narrow habitat preference for abiotic soil parameters. For 23 different abiotic soil parameters, of which the most influential were groundwater-table, soil-pH and nutrient-contents, we estimated species responses for common and rare species. Based on the responses per species we calculated the range of occurrence, the range between the 5 and 95 percentile of the response curve giving the habitat preference. Subsequently, we calculated the average response range for common and rare species. In addition, we designed a new graphic in order to provide a better means for presentation of the results. The habitat preferences of rare species for abiotic soil conditions are significantly narrower than for common species. Twenty of the twenty-three abiotic parameters showed on average significantly narrower habitat preferences for rare species than for common species; none of the abiotic parameters showed on average a narrower habitat preference for common species. The results have major implications for the conservation of rare plant species; accordingly management and nature development should be focussed on the maintenance and creation of a broad range of environmental conditions, so that the requirements of rare species are met. The conservation of (abiotic) gradients within ecosystems is particularly important for preserving rare species.

  15. Why Beauty Still Cannot Be Measured

    Directory of Open Access Journals (Sweden)

    Ossi Naukkarinen

    2010-01-01

    Full Text Available This article focuses on the question of whether the latest results achieved in sciences such as evolution studies and brain research can help us understand the nature of aesthetic judgments. It suggests that such approaches may offer interesting insights for understanding many problems in aesthetics, but for clarifying aesthetic judgments one needs a philosophical point of view. Aesthetic judgments cannot be proven right or wrong by scientific methods, and beauty or other aesthetic qualities cannot be directly measured. The “method” of both making and analyzing aesthetic judgments is discussion, and the article clarifies why this is still the case, even if empirical, non-philosophical scientific methods are more accurate than ever before.

    Postma, Jeroen; Roos, Anne-Fleur

    2016-04-01

    In many OECD countries, healthcare sectors have become increasingly concentrated as a result of mergers. However, detailed empirical insight into why healthcare providers merge is lacking. Also, we know little about the influence of national healthcare policies on mergers. We fill this gap in the literature by conducting a survey study on mergers among 848 Dutch healthcare executives, of which 35% responded (resulting in a study sample of 239 executives). A total of 65% of the respondents was involved in at least one merger between 2005 and 2012. During this period, Dutch healthcare providers faced a number of policy changes, including increasing competition, more pressure from purchasers, growing financial risks, de-institutionalisation of long-term care and decentralisation of healthcare services to municipalities. Our empirical study shows that healthcare providers predominantly merge to improve the provision of healthcare services and to strengthen their market position. Also efficiency and financial reasons are important drivers of merger activity in healthcare. We find that motives for merger are related to changes in health policies, in particular to the increasing pressure from competitors, insurers and municipalities.

  6. Comparison of amino acids physico-chemical properties and usage of late embryogenesis abundant proteins, hydrophilins and WHy domain.

    Science.gov (United States)

    Jaspard, Emmanuel; Hunault, Gilles

    2014-01-01

    Late Embryogenesis Abundant proteins (LEAPs) comprise several diverse protein families and are mostly involved in stress tolerance. Most of LEAPs are intrinsically disordered and thus poorly functionally characterized. LEAPs have been classified and a large number of their physico-chemical properties have been statistically analyzed. LEAPs were previously proposed to be a subset of a very wide family of proteins called hydrophilins, while a domain called WHy (Water stress and Hypersensitive response) was found in LEAP class 8 (according to our previous classification). Since little is known about hydrophilins and WHy domain, the cross-analysis of their amino acids physico-chemical properties and amino acids usage together with those of LEAPs helps to describe some of their structural features and to make hypothesis about their function. Physico-chemical properties of hydrophilins and WHy domain strongly suggest their role in dehydration tolerance, probably by interacting with water and small polar molecules. The computational analysis reveals that LEAP class 8 and hydrophilins are distinct protein families and that not all LEAPs are a protein subset of hydrophilins family as proposed earlier. Hydrophilins seem related to LEAP class 2 (also called dehydrins) and to Heat Shock Proteins 12 (HSP12). Hydrophilins are likely unstructured proteins while WHy domain is structured. LEAP class 2, hydrophilins and WHy domain are thus proposed to share a common physiological role by interacting with water or other polar/charged small molecules, hence contributing to dehydration tolerance.

    Liu, Shuming; Li, Ruonan; Smith, Kate; Che, Han

    2016-04-15

    Early warning systems are widely used to safeguard water security, but their effectiveness has raised many questions. To understand why conventional detection methods fail to identify contamination events, this study evaluates the performance of three contamination detection methods using data from a real contamination accident and two artificial datasets constructed using a widely applied contamination data construction approach. Results show that the Pearson correlation Euclidean distance (PE) based detection method performs better for real contamination incidents, while the Euclidean distance method (MED) and linear prediction filter (LPF) method are more suitable for detecting sudden spike-like variation. This analysis revealed why the conventional MED and LPF methods failed to identify existence of contamination events. The analysis also revealed that the widely used contamination data construction approach is misleading. Copyright © 2016 Elsevier Ltd. All rights reserved.

  9. How we live and why we die the secret lives of cells

    CERN Document Server

    Wolpert, Lewis

    2009-01-01

    Cells are the basis of all life in the universe. Our bodies are made up of billions of them: an incredibly complex society that governs everything, from movement to memory and imagination. When we age, it is because our cells slow down; when we get ill, it is because our cells mutate or stop working. In "How We Live and Why we Die", Wolpert provides a clear explanation of the science that underpins our lives. He explains how our bodies function and how we derived from a single cell - the embryo. He examines the science behind the topics that are much discussed but rarely understood - stem-cell research, cloning, DNA - and explains how all life evolved from just one cell. Lively and passionate, "How We Live and Why we Die" is an accessible guide to understanding the human body and, essentially, life itself.

  13. Burned Out Or Just Frustrated? Reasons Why Physical Education Teachers Leave Their Profession

    Directory of Open Access Journals (Sweden)

    Cieśliński Ryszard

    2014-09-01

    Full Text Available This work focuses on the reasons why physical education (PE teachers leave their profession. The study included 80 individuals who decided to leave a teaching profession in 2013. A diagnostic poll method with the use of the QWL (Quality of Work Life index was employed in the study. It was observed that there are usually a number of reasons why they give up their job, the most important being financial reasons. Their decision is influenced by the accumulation of professional and personal problems as well as their inability to solve them. The findings showed that teachers‘ departure from the profession is generally associated with the issue of burnout; however, financial reasons are most frequently ones that directly affect this decision.

  14. Why Do Sex Chromosomes Stop Recombining?

    Science.gov (United States)

    Ponnikas, Suvi; Sigeman, Hanna; Abbott, Jessica K; Hansson, Bengt

    2018-04-28

    It is commonly assumed that sex chromosomes evolve recombination suppression because selection favours linkage between sex-determining and sexually antagonistic genes. However, although the role of sexual antagonism during sex chromosome evolution has attained strong support from theory, experimental and observational evidence is rare or equivocal. Here, we highlight alternative, often neglected, hypotheses for recombination suppression on sex chromosomes, which invoke meiotic drive, heterozygote advantage, and genetic drift, respectively. We contrast the hypotheses, the situations when they are likely to be of importance, and outline why it is surprisingly difficult to test them. Lastly, we discuss future research directions (including modelling, population genomics, comparative approaches, and experiments) to disentangle the different hypotheses of sex chromosome evolution.

    Wibbelt, Gudrun; Moore, Marianne S.; Schountz, Tony; Voigt, Christian C.

    2010-01-01

    A conference entitled ‘2nd International Berlin Bat Meeting: Bat Biology and Infectious Diseases’ was held between the 19 and 21 of February 2010 in Berlin, Germany. Researchers from two major disciplines, bat biologists and disease specialists, met for the first time in an interdisciplinary event to share their knowledge about bat-associated diseases. The focus of the meeting was to understand why in particular bats are the hosts of so many of the most virulent diseases globally. During several sessions, key note speakers and participants discussed infectious diseases associated with bats, including viral diseases caused by Henipa-, Filo-, Corona- and Lyssaviruses, the spread of white-nose syndrome in North American bats, bat immunology/immunogenetics, bat parasites, and finally, conservation and human health issues.

  16. Stormwater management the American way: why no policy transfer?

    Directory of Open Access Journals (Sweden)

    David P. Dolowitz

    2015-09-01

    Full Text Available From the 1940s until the 1980s the federal government gradually extended its authority over the structure of the American stormwater management system. The goal was to improve the water quality of the nation’s waterways by regulating the pollution loads entering the system, primarily through the use of gray infrastructure. However during the1980s the Environmental Protection Agency (EPA began to explore new approaches toward the regulation of stormwater pollution. Instead of focusing only on gray mechanisms, the EPA began developing and promoting the use of low impact development (LID techniques as an element municipal governments could use to achieve their total maxim daily load of pollutants allowable under the National Pollutant Discharge Elimination System permit system. In light of the incentive offered by the EPA for the use of LID in the management of stormwater, it should be expected to provide a perfect area to observe policy transfer between federal, state and local governments; but it does not. This article will establish why the EPA began promoting a green approach to stormwater management and why this has not led to a widespread transfer of best management practices in the ways the literatures associated with federalism and policy transfer would suggest.

  1. Difficulties of learning probability concepts, the reasons why these concepts cannot be learned and suggestions for solution

    Directory of Open Access Journals (Sweden)

    Dilek Sezgin MEMNUN

    2008-06-01

    Full Text Available Probability holds the first place among the subjects that both teachers and students have difficulty in handling. Although probability has an important role in many professions and a great many decisions we make for our daily lives, the understanding of the probability concepts is not an easy ability to gain for many students. Most of the students develop perception about lots of probability concepts and they have difficulty finding a reason for probability events. Thus, in the present study, the difficulties faced while learning probability concepts and the reasons why these concepts cannot be learned well are investigated, these reasons are tried to be put forward, and some suggestions for solutions regarding these concepts are presented. In this study, cross-hatching model was used. National and international studies on the subject of probability are investigated, the reasons why these concepts cannot be learned were categorized in the light of findings obtained, and the reasons why these concepts cannot be learned and taught are tried to be discovered. The categorization was displayed with Ishikawa diagram. In the diagram, the reasons why these concepts cannot be learned were noted as six categories. These categories were age, the insufficiency of advanced information, the deficiency of argumentation ability, teacher, error in concept, and students’ negative attitudes.

  2. Why doctors have difficulty with sex histories.

    Science.gov (United States)

    Merrill, J M; Laux, L F; Thornby, J I

    1990-06-01

    Studies have shown that physicians' performance has not been as good as it should be in detecting sexually transmitted diseases (STDs) and in counseling patients about their transmission. The AIDS pandemic has underscored the need to find out why this is true. In our study, we identified the major reasons physicians believe other doctors fail to take adequate sex histories. Scales were then developed to measure the three principal reasons given by these physicians: embarrassment, belief that the sex history is not relevant to the patient's chief complaint, and belief by the physicians that they are not adequately trained. When 350 senior medical students were surveyed, 93% thought that knowledge of a patient's sexual practices is an important part of their patient's medical history, but 50% felt poorly trained to take this history and 25% felt embarrassed to ask the necessary questions. To learn why some students score well on these three dimensions and others do not, a limited number of personal attributes were measured and correlated with the scores on these three measures. Shyness and social anxiety as a personal trait predicted which student was most likely to experience embarrassment in taking a sex history. A nonsympathetic view of patients' psychosocial problems was the variable most closely related to the belief that the sex history was of little importance in understanding a patient's problem. Students who believed this most strongly were the same ones who were most homophobic, authoritarian, and had the greatest fear of AIDS infection. The sense of not feeling adequately trained to take a sex history related most strongly to low self-esteem. How these barriers to STD risk assessment might be overcome is discussed.

  11. Temporary employment in Russia: why mostly men?

    Directory of Open Access Journals (Sweden)

    Tatiana Karabchuk

    2012-08-01

    Full Text Available The paper deals with temporary employment in the Russian labour market. The main focus is the gender difference regarding determinants of temporary employment. Unlike most European countries, where women are more likely to have temporary work, in Russia men predominantly have this status, comparable to the situation in many developing countries. This paper seeks to understand why this is the case. The household survey of NOBUS (held in 2003 by State Statistical Centre with World Bank participation is used to answer this question: the results suggest that gender differences in temporary employment do exist, and that the main factors that explain these differences are education, and marital status.

  12. Why nature doesn't turn off neurosis.

    Science.gov (United States)

    Badalamenti, Anthony F

    2013-03-01

    This paper develops an integration of psychoanalytic and wisdom tradition concepts to answer the question as to why nature does not turn off neurosis, The proposed answer is that nature wants a person to exploit the neurosis for two gains, one being the increase in adaptive capacity resulting from releasing it and the second involving the difficulty in the release itself, the latter related to gains proffered by the world's wisdom traditions. These see a movement from the psyche's creation by passive, unconscious means of finite promise rooted in parental love to creation by active, consciously chosen means of unlimited promise involving a direct relationship with nature and the Cosmos.

    2012-05-01

    To identify the reasons why interns would not choose a surgical career. This qualitative study used semi-structured telephone interviews to explore the future career choices of 41 junior doctors (14 men, 27 women). Doctors were asked to identify specialties they would not take up, and state why this was the case. Thirty (73.2%) of the 41 interns nominated surgery as a specialty they would not choose. Themes relating to reasons for not wanting to pursue a surgical career included the lifestyle associated with surgery (66.7%), the culture within the surgical work environment (53.3%), the lack of interest in performing surgical work (36.7%), and the training requirements associated with surgery (33.3%). Both sexes had similar reasons for not wanting to choose a surgical career; but additionally, women referred to the male domination of surgery, and the difficulty and inflexibility of the training program as deterrents. Efforts are needed to promote interest in surgery as a career especially for women, to improve the surgical work environment so that medical students and junior doctors have exposure to positive role models and surgical placements, and to provide a more flexible approach to surgical training.

    Harrison, Tyler L; Shipstead, Zach; Engle, Randall W

    2015-04-01

    One of the reasons why working memory capacity is so widely researched is its substantial relationship with fluid intelligence. Although this relationship has been found in numerous studies, researchers have been unable to provide a conclusive answer as to why the two constructs are related. In a recent study, researchers examined which attributes of Raven's Progressive Matrices were most strongly linked with working memory capacity (Wiley, Jarosz, Cushen, & Colflesh, Journal of Experimental Psychology: Learning, Memory, and Cognition, 37, 256-263, 2011). In that study, Raven's problems that required a novel combination of rules to solve were more strongly correlated with working memory capacity than were problems that did not. In the present study, we wanted to conceptually replicate the Wiley et al. results while controlling for a few potential confounds. Thus, we experimentally manipulated whether a problem required a novel combination of rules and found that repeated-rule-combination problems were more strongly related to working memory capacity than were novel-rule-combination problems. The relationship to other measures of fluid intelligence did not change based on whether the problem required a novel rule combination.

  18. Exams? Why worry? Interpreting anxiety as facilitative and stress appraisals.

    Strack, Juliane; Esteves, Francisco

    2015-01-01

    The present study examined why people differ in how they appraise the same stressful situation (an approaching exam). We explored whether interpreting anxiety as a facilitative emotion can affect the type of stress appraisal people make. One hundred and three undergraduate students took part in this study, which lasted for 10 days (leading up to an exam). The students completed a daily self-reported evaluation of anxiety, emotional exhaustion, and stress experienced. The findings suggest a process by which a stressful time can be experienced as motivating rather than threatening or emotionally exhausting. For example, interpreting anxiety as facilitative moderated the relationship between anxiety and stress appraisals. When interpreting their anxiety as facilitative, individuals showed a higher tendency to make challenge stress appraisals and a lower tendency to appraising the stressor as a threat. These differences were especially visible with high levels of anxiety. Furthermore, interpreting anxiety as facilitative was negatively associated with emotional exhaustion, but positively associated with the academic performance. These findings suggest an explanation why people differ in how they appraise the same stressor: how people interpret their anxiety may to a large part affect how they appraise difficult events and situations.

  1. A super-assembly of Whi3 encodes memory of deceptive encounters by single cells during yeast courtship.

    Science.gov (United States)

    Caudron, Fabrice; Barral, Yves

    2013-12-05

    Cellular behavior is frequently influenced by the cell's history, indicating that single cells may memorize past events. We report that budding yeast permanently escape pheromone-induced cell-cycle arrest when experiencing a deceptive mating attempt, i.e., not reaching their putative partner within reasonable time. This acquired behavior depends on super-assembly and inactivation of the G1/S inhibitor Whi3, which liberates the G1 cyclin Cln3 from translational inhibition. Super-assembly of Whi3 is a slow response to pheromone, driven by polyQ and polyN domains, counteracted by Hsp70, and stable over generations. Unlike prion aggregates, Whi3 super-assemblies are not inherited mitotically but segregate to the mother cell. We propose that such polyQ- and polyN-based elements, termed here mnemons, act as cellular memory devices to encode previous environmental conditions. Copyright © 2013 Elsevier Inc.

    2018-01-01

    If you ask most health professionals why they do what they do, they invariably speak of being of service. And being of service, for population health workers, becomes ever more meaningful as our work touches ever more lives. To wit, "Kaizen," a Japanese term meaning "change for better," sits shoulder to shoulder with our life's purpose. Health promotion professionals are high performers getting great results but we need to start working on our work. What would it take to increase our impact by 50%? And when we change our processes to accomplish that, what would we change next to get another 50% improvement? Only by stepping back and examining our processes can we see the time and motion required to make what's working now work better and be more accessible to more people next time.

    These are a set of slides from the conference. Lignocellulosic biomass is the most abundant, least expensive renewable natural biological resource for the production of biobased products and bioenergy is important for the sustainable development of human civilization in 21st century. For making the fermentable sugars from lignocellulosic biomass, a reduction in cellulase production cost, an improvement in cellulase performance, and an increase in sugar yields are all vital to reduce the processing costs of biorefineries. Improvements in specific cellulase activities for non-complexed cellulase mixtures can be implemented through cellulase engineering based on rational design or directed evolution for each cellulase component enzyme, as well as on the reconstitution of cellulase components. In this paper, we will provide DSM's efforts in cellulase research and developments and focus on limitations. Cellulase improvement strategies based on directed evolution using screening on relevant substrates, screening for higher thermal tolerance based on activity screening approaches such as continuous culture using insoluble cellulosic substrates as a powerful selection tool for enriching beneficial cellulase mutants from the large library. We will illustrate why and how thermostable cellulases are vital for economic delivery of bioproducts from cellulosic biomass using biochemical conversion approach.

  8. The Seneca effect why growth is slow but collapse is rapid

    CERN Document Server

    Bardi, Ugo

    2017-01-01

    The essence of this book can be found in a line written by the ancient Roman Stoic Philosopher Lucius Annaeus Seneca: "Fortune is of sluggish growth, but ruin is rapid". This sentence summarizes the features of the phenomenon that we call "collapse," which is typically sudden and often unexpected, like the proverbial "house of cards." But why are such collapses so common, and what generates them? Several books have been published on the subject, including the well-known "Collapse" by Jared Diamond (2005), "The collapse of complex societies" by Joseph Tainter (1998) and "The Tipping Point," by Malcom Gladwell (2000). Why The Seneca Effect? This book is an ambitious attempt to pull these various strands together by describing collapse from a multi-disciplinary viewpoint. The reader will discover how collapse is a collective phenomenon that occurs in what we call today "complex systems," with a special emphasis on system dynamics and t he concept of "feedback." From this foundation, Bardi applies the...

    Directory of Open Access Journals (Sweden)

    2015-12-01

    Full Text Available The article deals with the question which management philosophy is better, management philosophy based on culture HOW or management philosophy based on culture WHY. With respect to this article, author used these techniques, namely quantitative research, case methodology and literature analysis. Consequently, from the research, it can be predicted that most companies prefer a management model which inclines more towards planning, organizing and controlling than to leadership. This approach is a part of the traditional management system through which the organizational culture of “HOW” is implemented. The hidden costs of this model are apathetic staff, lost revenues and mainly work-related stress. These factors, which cause a lack of participation in the workplace, similarly lead to paralysis of innovation capabilities of most companies. They negatively affect the overall productivity of the economy and cause considerable social costs. However, there is also alternative management system based on the WHY culture. This management system, which releases initiative, creativity and enthusiasm, was investigated in the Toyota, FAVI and W. L. Gore. Author found out that these companies are able to eliminate the negative consequences of the traditional management model. The key features of this model are trust, freedom and responsibility, all three of which enrich the system with the ability to learn iteratively from one’s own mistakes.

  11. Monitoring irrigation water consumption using high resolution NDVI image time series (Sentinel-2 like). Calibration and validation in the Kairouan plain (Tunisia)

    Water scarcity is one of the main factors limiting agricultural development in semi-arid areas. It is thus of major importance to design tools allowing a better management of this resource. Remote sensing has long been used for computing evapotranspiration estimates, which is an input for crop water balance monitoring. Up to now, only medium and low resolution data (e.g. MODIS) are available on regular basis to monitor cultivated areas. However, the increasing availability of high resolution high repetitivity VIS-NIR remote sensing, like the forthcoming Sentinel-2 mission to be lunched in 2015, offers unprecedented opportunity to improve this monitoring. In this study, regional crops water consumption was estimated with the SAMIR software (Satellite of Monitoring Irrigation) using the FAO-56 dual crop coefficient water balance model fed with high resolution NDVI image time series providing estimates of both the actual basal crop coefficient (Kcb) and the vegetation fraction cover. The model includes a soil water model, requiring the knowledge of soil water holding capacity, maximum rooting depth, and water inputs. As irrigations are usually not known on large areas, they are simulated based on rules reproducing the farmer practices. The main objective of this work is to assess the operationality and accuracy of SAMIR at plot and perimeter scales, when several land use types (winter cereals, summer vegetables…), irrigation and agricultural practices are intertwined in a given landscape, including complex canopies such as sparse orchards. Meteorological ground stations were used to compute the reference evapotranspiration and get the rainfall depths. Two time series of ten and fourteen high-resolution SPOT5 have been acquired for the 2008-2009 and 2012-2013 hydrological years over an irrigated area in central Tunisia. They span the various successive crop seasons. The images were radiometrically corrected, first, using the SMAC6s Algorithm, second, using invariant

    2011-01-01

    In this study the author examined why children and adults think they need to eat. Preschoolers through adults were provided with physiological, social, psychological, and routine causes for eating breakfast, lunch, snack, and dinner, and were asked to either agree or disagree with the causal responses provided. A 4 Reason x 4 Meal repeated measures analysis of variance revealed significant main effects for meals and reasons, as well as significant Meal x Reason and Meal x Reason x Grade interactions. The effect sizes ranged from 0.1 to 0.7. Across all age groups, participants acknowledged physiological needs and desires (fulfilling hunger and needs to stay healthy) and routine (e.g., it is dinner time) as the primary causes for eating breakfast, lunch, and dinner. However, for snack physiological needs were the primary reason. Second-grade students onward spontaneously produced biological justifications such as the need for energy and nutrition as important reasons for food consumption. These results lend support to the developmental model that children's and adults' understanding of eating changes in middle childhood.

    Work is one of the most valued social rules in modern society, contributing to a person's sense of economic well-being, self-esteem, personal identity, and social status. Conversely, the inability to work or sustain employment due to a psychiatric condition is the primary factor in determining eligibility for disability benefits, such as Social Security Disability Income or Social Security Supplemental Income. Just as work is valued strongly by society, it is also important to people with serious mental illness. In this editorial, we contemplate why we cannot "do the right thing" and fully fund supported employment for persons with serious mental illness.

    Gjesdal, Siv; Appleton, Paul R; Ommundsen, Yngvar

    2017-01-01

    This study builds on previous research combining achievement goal orientation from Achievement Goal Theory and motivational regulation from Self-Determination Theory. The aim was to assess the combination of the "what" and "why" of youth sport activity, and how it relates to the need for competence and self-esteem. Achievement goal orientation, specifically task and ego, was employed to represent the "what", whilst intrinsic and external regulation reflected the "why". Based on a sample of 496 youth sports participants, structural equation modeling with a bootstrapping procedure was used to examine whether the indirect relationship between achievement goal orientation and self-esteem was conditional to motivational regulation. The results show partial support for the conditional process models. Specifically, task orientation was indirectly linked with self-esteem through competence need, and the relationship was stronger with higher levels of intrinsic regulation for sport. Furthermore, ego orientation was negatively associated with self-esteem through a positive relationship with competence frustration. However, this relationship emerged only for those higher in intrinsic regulation. External regulation did not emerge as a moderator, but presented a positive relationship with competence frustration. Findings are discussed in light of both Achievement Goal Theory and Self-Determination Theory, and underline the importance of considering both the "what" and "why" when attempting to understand motivation in youth sport.

    Directory of Open Access Journals (Sweden)

    Norman D. Cook

    2007-01-01

    Full Text Available The relative consonance/dissonance of 2-tone intervals is well understood both experimentally and theoretically and provides a strong foundation for explaining why diatonic scales or their subsets are used in most musical cultures. Frequent textbook assertions notwithstanding, however, the consonance of intervals fails to account for the basic facts of harmony (3 or more tone combinations. We have recently shown (Cook & Fujisawa, 2006 how consideration of 3-tone psychophysics can explain the fundamental regularities of diatonic harmony. Distinct from the dissonance of 2-tone intervals, 3-tone combinations introduce an effect described by Leonard Meyer (1956 as harmonic “tension”: when a third tone is located midway between an upper and a lower tone, the chord takes on an unresolved, unstable, tense character – a psychoacoustical property inherent to the diminished and augmented chords. If the effects of the upper partials are included in a formal model that includes both 2-tone and 3-tone effects, the perceived sonority of the triads (major>minor> diminished>augmented is easily explained.

    In both China and the United States, public attitudes toward intimate partner violence (IPV) have shifted from viewing IPV as a tolerable, private matter to viewing it as a matter of public concern that should be dealt with as a crime. Empirical and comparative examinations of the perceptions of why women stay in physically abusive relationships are lacking. Answering this question calls for comprehensive, methodologically rigorous research. Using survey data collected from approximately 1,000 college students from two Chinese and two U.S. universities, this study empirically compared and contrasted factors that impact U.S. and Chinese students' perceptions as to why women remain in physically abusive relationships. Utilizing a theoretical framework of social constructionism, two common reasons were assessed: Women stay in physically abusive relationships because of learned helplessness and positive beliefs in the relationship/hope for the future. The results show that viewing IPV as a crime, gender, and beliefs of the causes of IPV were robust predictors of college students' perceptions toward why women stay in physically abusive relationships. U.S. college students were more likely to express sympathy and understanding toward why women remain in abusive relationships than Chinese students. Directions for future research and policy implications were discussed.

  15. If meaningfulness is not always fulfilling, why then does it matter?

    Full Text Available We start from a quandary in the field of meaningfulness introduced by Susan Wolf, who attempts to make clear why meaning in life would matter. In common sense terms, fulfilment is considered to play a main role in the conceptualisation of meaningfulness. While initially taking this also for granted Wolf gradually comprehends that fulfilment is not the overall reason why meaning in life matters. She leaves however open the paramount question of what would make it then so particular. In this article, we explore this query to a fuller extent, and maintain that a promising road to an answer lays in the understanding that meaning in life is directive in an ineffable way. In order to fathom what this entails, a distinction between meaningfulness’ and ‘meaning in life’ will prove helpful. Both have often been considered synonyms, but we argue that they are quite distinct, yet intrinsically related. Starting from a subject that is mainly discussed in analytic philosophy, we build a bridge to phenomenological praxis, indicating that we can only understand its core function - its ineffable way of being directive - through phenomenology.

    2015-01-01

    Full Text Available In this paper I speak from both a scientific and religious perspective. From this dual perspective I question the motivations that drive us to continue in the effort of doing scientific work. I ask the why and the wherefore of scientific work. To answer this question: What drives us to continue doing Science? I raise a preliminary question: What do we mean when we say ‘Science’? After briefly describing how the language of Modern Science has evolved in the last centuries, I distinguish between the knowledge that can be expressed by the formal languages of mathematics and the more personal and internal knowledge that can only be expressed by other languages that I call languages of symbol. Finally I propose positive and religious values that move us to continue doing science, while, together with more critical voices, also show the relativity of scientific work

  19. Why adolescent boys dream of becoming professional athletes.

    Stiles, D A; Gibbons, J L; Sebben, D J; Wiley, D C

    1999-06-01

    A review of studies which investigated drawings of the ideal man and the occupational aspirations of boys (ages 11-18 years) from several countries indicated that becoming a professional athlete was a popular but unrealistic aspiration for many adolescent boys. Boys who were athletes and nonathletes from diverse ethnic groups and nationalities dreamed of becoming professional athletes. In two additional studies in the United States of America, adolescents were asked why they thought boys most often selected professional athlete as a possible future occupation. Adolescents perceived professional athletes as rich, famous, and glorified. Enhancement of status and financial gain were ranked as more important than the desire to play sports.

  20. Review of Eagleton’s Why Marx Was Right

    Directory of Open Access Journals (Sweden)

    2011-04-01

    Full Text Available This article is a critical review of Terry Eagleton’s latest publication, Why Marx Was Right (2011. Eagleton, one of the more celebrated Marxist literary critics in academia, presents his readers with a manifesto of Marxian individualism for the budding theoreticians of market socialism. This book represents Eagleton’s latest sally from the cloisters of stuffy English departments into the realms of economic theory. I cover many of the book’s most important talking points, debate his primary theses with ample counterpoints, and probe Eagleton’s vision of the socialist future from an Austrian angle to see where the author succeeds and falls short of his mark.

    The recent initial public offering of shares of Zynga, probably the most important on-line game provider, drew interest of potential investors but also of general public to their business model. What the most interested people learned so far is that if Zynga had not changed their accounting...... practice, they would be in red numbers for several months already. This is most likely caused by people stopping to play their games. This paper provides an estimate of what proportion of people, who played on-line games, already stopped playing them.

    Flying cars in The Jetsons and Back to the Future, or Star Trek’s spaceships and teleportation, may have captured the imagination decades ago, but most current methods of transport have been around a long time. So why has there been so little recent innovation in transport? And will the latest batch of proposed driverless cars, levitating trains and electric aircraft actually make a serious breakthrough?

  4. Shifman-Vainshtein-Zakharov method: why it works, why it fails, and ways to improve it

    International Nuclear Information System (INIS)

    Durand, L.; Durand, B.; Whitenton, J.B.

    1983-01-01

    Shifman, Vainshtein, and Zakharov (SVZ) have proposed a procedure for calculating hadronic masses and determining nonperturbative parameters in QCD using the operator-product expansion for two-point functions and (exponential) moments of the corresponding spectral functions. In this paper we present a detailed theoretical analysis of the SVZ procedure in the context of nonrelativistic potential theory. We find that the phenomenological success of the usual first-order SVZ method in relating hadronic energies (masses) is due to a hidden variational principle and a semiclassical structure which gives correct JWKB-type relations between energies. The first-order method fails theoretically: it does not reproduce the correct potential-model or field-theoretic parameters, e.g., the gluon-condensate parameter of QCD. We show why it breaks down in this application, and that its reliability can be greatly improved in all applications by using higher-order approximations for the moment function. Our results are directly relevant for the SVZ analysis of charmonium and b-quarkonium. The general conclusions should also hold for light-quark systems

  10. 13 reasons why the brain is susceptible to oxidative stress

    OpenAIRE

    James Nathan Cobley; Maria Luisa Fiorello; Damian Miles Bailey

    2018-01-01

    The human brain consumes 20% of the total basal oxygen (O2) budget to support ATP intensive neuronal activity. Without sufficient O2 to support ATP demands, neuronal activity fails, such that, even transient ischemia is neurodegenerative. While the essentiality of O2 to brain function is clear, how oxidative stress causes neurodegeneration is ambiguous. Ambiguity exists because many of the reasons why the brain is susceptible to oxidative stress remain obscure. Many are erroneously understood...

    Horner and Sugai (2015) recently wrote a manuscript providing an overview of school-wide positive behavioral interventions and supports (PBIS) and why it is an example of applied behavior analysis at the scale of social importance. This paper will describe why school-wide PBIS is important to behavior analysts, how it helps promote applied behavior analysis in schools and other organizations, and how behavior analysts can use this framework to assist them in the promotion and implementation of applied behavior analysis at both at the school and organizational level, as well as, the classroom and individual level.

  16. Exile and Self-Actualization in Pauline Kaldas’s “He Had Dreamed of Returning” and “Airport”

    Directory of Open Access Journals (Sweden)

    Nisreen M. Sawwa

    2017-01-01

    Full Text Available Against common pessimistic readings of exile in postcolonial fiction, this article employs the notion of “self-actualization” that argues for people’s desire to accomplish everything they are capable of and their need to realize their potential. Within a comparative context and using identity theory and diaspora studies, the article illustrates how self-actualization keeps the immigrants from experiencing exile in two Arab American short stories by Pauline Kaldas: “Airport” (2009a and “He Had Dreamed of Returning” (2009b. This article shows how the main characters of “Airport” and “He Had Dreamed of Returning,” Samir and Hani respectively, fulfill the American Dream and how Hoda, Samir’s wife, pictures America as the place where she can realize her ambitions. However, Nancy, Hani’s wife, achieves her potential in Egypt rather than America, where she feels needed as a teacher. Thus, Samir and Hani do not get dislocated in America, and Nancy has a sense of belonging in Egypt. Hence, the article utilizes the American Dream and a reverse side of it, and it shows how Samir’s, Hani’s, and Nancy’s self-actualization is a counter to feelings of exile. In other words, the three characters do not experience loss of identity and displacement in the countries they emigrate to. Rather, they fulfill their dreams there and find/create new identities which have been suppressed in their hometowns, which enhances a view of identity as fluid rather than fixed. Briefly put, this article presents the self-actualization of immigrants in new locales as a counter to different levels of dislocation and exile.

  17. Evaluation of local tolerance of the antiretroviral spermicide (WHI-07)-loaded gel-microemulsion in the porcine female reproductive tract.

    2008-04-01

    The local tolerance of the antiretroviral spermicide, WHI-07 (5-bromo-6-methoxy-5,6-dihydro-3'-azidothymidine-5'-(p-bromophenyl)-methoxyalaninyl phosphate)-loaded gel-microemulsion was evaluated in a physiologically relevant and sensitive porcine model. Gilts (Duroc) in nonestrus stages of the reproductive cycle received either a single or a daily intravaginal application of 2.0% WHI-07 via a gel-microemulsion for 6 days. Cervicovaginal lavage (CVL) fluid was obtained for up to 72 h after a single exposure and the cellular profile and levels of inflammatory cytokines (IL-1beta, IL-8, IFN-gamma and TNF-alpha) were quantitated by flow cytometry and chemiluminescence-based multiplex immunoassay, respectively. The reproductive tract (vagina, cervix, uteri and Fallopian tubes) harvested on day 7 was scored histologically for evidence of mucosal irritation using a new scoring criterion for ten histological endpoints that reflect pathological changes in the epithelial/ subepithelial and vascular/perivascular compartments. When compared with irritant reactions caused by the detergent-type spermicide, benzalkonium chloride (BZK), the scatter profile of CVL immune cells and basal levels of proinflammatory cytokines (IL-1beta, IL-8, IFN-gamma and TNF-alpha) in CVL fluid were unaffected by intravaginal exposure to 2% WHI-07. Unlike BZK, endpoint histology of the proximal and distal regions of the reproductive tract from gilts treated with 2.0% WHI-07 via gel-microemulsion for 6 days did not result in mucosal irritation or alteration in the epithelium, subepithelium/lamina propria, vessels/perivascular tissues and underlying/surrounding muscles. Based on surrogate markers for inflammation, leukocyte profile and histologic data for local tolerance, repeated intravaginal administration of WHI-07 via gel-microemulsion as a prophylactic contraceptive is unlikely to cause vaginal irritation.

    2016-12-15

    The European Economic and Social Committee (EESC) has called for a more comprehensive strategy to be incorporated in a revised version of the European Commission's (EC) Illustrative Programme for Nuclear Energy (PINC). EESC member Brian Curtis tells NucNet why the PINC has failed to address key issues for nuclear and why he believes the EC has become side-tracked by renewables. The EESC is a consultative body which represents the interests of civil society organisations and stakeholders at the EU. Its opinions are forwarded to the EC, the European Council, and the European Parliament and are considered in the EU's decision-making process.

  7. Charting the future course of rural health and remote health in Australia: Why we need theory.

    Science.gov (United States)

    Bourke, Lisa; Humphreys, John S; Wakerman, John; Taylor, Judy

    2010-04-01

    This paper argues that rural and remote health is in need of theoretical development. Based on the authors' discussions, reflections and critical analyses of literature, this paper proposes key reasons why rural and remote health warrants the development of theoretical frameworks. The paper cites five reasons why theory is needed: (i) theory provides an approach for how a topic is studied; (ii) theory articulates key assumptions in knowledge development; (iii) theory systematises knowledge, enabling it to be transferable; (iv) theory provides predictability; and (v) theory enables comprehensive understanding. This paper concludes with a call for theoretical development in both rural and remote health to expand its knowledge and be more relevant to improving health care for rural Australians.

    Full Text Available Background: The motivations behind why people choose to study medicine in Iraqi medical schools are unknown. Such information could help school pupils to make more informed career decisions and assist medical schools in enhancing the student selection process. Aims: To investigate why people choose to study medicine in Iraq. Subjects and methods: The first-year students admitted on the academic year 2015-2016 to Baghdad College of Medicine, University of Baghdad, were invited to complete a structured questionnaire, which was administered through the college electronic education portal. The data were analyzed using IBM SPSS version 21 software. Results: A total of 152 (50% response rate students responded. Women constituted 69.1% of respondents. Most students (61.8% had made their choice by themselves without family pressure. The most frequent reasons that affected this choice were “humanitarian reasons and a wish to provide help to others” as well as “childhood dream,” “positive community appraisal of doctors,” and “ready availability of work for physicians.” About three-quarters (73.6% of the students made some inquiry about medical school before making their choice, and the people asked were most frequently a medical student or a doctor. Information provided by the consulted parties was regarded as satisfactory by 64.2% of the surveyed students, had a positive value in 47.2%, and affected their decision in 34.9%. The highest proportion (42.2% of the study sample was thinking about studying medicine since primary school. In addition, students with personal preference made their choice at a significantly younger age. Conclusions: Reasons to apply for medical schools in Iraq are similar to those in many countries. Most of the students who inquired about studying medicine had not contacted the medical school itself.

  9. Why Workers’ Rights Are Not Women’s Rights

    Directory of Open Access Journals (Sweden)

    Heidi Gottfried

    2015-04-01

    Full Text Available “Why workers’ rights are not women’s rights” is an argument whose purpose is to make clear why workers’ rights rest on a masculine embodiment of the labor subject and it is this masculine embodiment which is at the center of employment contracts and employment relations systems. By excavating the gender subjects implicit to and explicit in regulations of labor, the paper reveals the opposition of paired terms, masculinity and femininity privileging production over reproduction and naturalizing gender-based power relations. The paper identifies various laboring activities associated with differential rights and responsibilities. An examination of the treatment of part-time employment and waged caring labor, framed in labor, welfare, immigration, and citizenship policies and practices, locates exclusions from labor standards and exemptions from entitlements due to eligibility requirements and thresholds that assume the masculine embodiment of the worker-citizen. Gendering the analysis illustrates how contemporary labor laws and conventions grant rights on the basis of, and to, a rather abstract conception of the prototypical worker-citizen. Its origins lie in what classical political economy labeled a capitalist logic, as well as the historical practices in which free class agents entered into contracts for continuous, full-time work free of care responsibilities outside of the wage/labor nexus. Thus, it is this particular abstract construction of the proto-typical worker which instantiates the separation of “rights to” from “responsibilities for”, and it is this separation that allows the masculine embodiment of the labor subject. Modes of regulation privileging rights over responsibilities will valorize the masculine worker-citizen whose rights derive from their participation in wage labor and simultaneously devalue the feminine worker who is directly connected to caring labor.

    Efforts to prevent adolescents from smoking have limited efficacy, with little understanding of why they smoke. We examine many of the factors which may influence a teenager's decision to start smoking. A self-completed questionnaire was distributed among pre-draft teenagers (age 16-18 years) with questions regarding current smoking habits as well as smoking habits of family members. Smokers were asked why they started, and attitudes regarding the dangers of smoking and anti-smoking legislation were examined. A total of 1067 questionnaires were completed (707 males, 360 females). In all, 25.7% were current smokers (26.2% of male and 21.1% of females; p=0.069), with smoking rates highest among those born in Middle Eastern countries and lowest among those born in Ethiopia. Those from single-parent families had a higher smoking rate (relative risk: 1.28), as did those with either parents or siblings who smoked. Parents who were smokers were more likely to tell their children not to smoke, while smoking teenagers were more likely to have been told by their parents not to smoke. Most smokers (58.2%) did not give a specific reason for smoking while 30.3% listed "peer pressure", 8.4% "parents smoking" and 3.1% "advertisements" as the major factor. Smokers were less likely to agree that smoking is harmful and more likely to oppose anti-smoking legislative measures. Many factors influence a teenager's decision to smoke, including cultural norms and habits of friends and family members. Educating both adolescents and those around them may help prevent smoking among this age group.

  17. Why and when hierarchy impacts team effectiveness: A meta-analytic integration.

    Science.gov (United States)

    Greer, Lindred L; de Jong, Bart A; Schouten, Maartje E; Dannals, Jennifer E

    2018-06-01

    Hierarchy has the potential to both benefit and harm team effectiveness. In this article, we meta-analytically investigate different explanations for why and when hierarchy helps or hurts team effectiveness, drawing on results from 54 prior studies (N = 13,914 teams). Our findings show that, on net, hierarchy negatively impacts team effectiveness (performance: ρ = -.08; viability: ρ = -.11), and that this effect is mediated by increased conflict-enabling states. Additionally, we show that the negative relationship between hierarchy and team performance is exacerbated by aspects of the team structure (i.e., membership instability, skill differentiation) and the hierarchy itself (i.e., mutability), which make hierarchical teams prone to conflict. The predictions regarding the positive effect of hierarchy on team performance as mediated by coordination-enabling processes, and the moderating roles of several aspects of team tasks (i.e., interdependence, complexity) and the hierarchy (i.e., form) were not supported, with the exception that task ambiguity enhanced the positive effects of hierarchy. Given that our findings largely support dysfunctional views on hierarchy, future research is needed to understand when and why hierarchy may be more likely to live up to its purported functional benefits.

    Science.gov (United States)

    Ruchman, Samuel G; Singh, Prabhjot; Stapleton, Anna

    2016-07-01

    Why should health care systems in the United States engage with the world's poorest populations abroad while tremendous inequalities in health status and access are pervasive domestically? Traditionally, three arguments have bolstered global engagement: (1) a moral obligation to ensure opportunities to live, (2) a duty to protect against health threats, and (3) a desire to protect against economic downturns precipitated by health crises. We expand this conversation, arguing that US-based clinicians, organizational stewards, and researchers should engage with and learn from low-resource settings' systems and products that deliver high-quality, cost-effective, inclusive care in order to better respond to domestic inequities. Ultimately, connecting "local" and "global" efforts will benefit both populations and is not a sacrifice of one for the other. © 2016 American Medical Association. All Rights Reserved.

    2017-03-01

    Full Text Available Why did Jesus refer to Himself as the “Bread of Life”? Obviously, He intended to give us the gift of Himself in the Eucharist. But why did He choose the form of bread? Beginning with the first use of the word “bread” in the Masoretic Text of the Book of Genesis and the etymological meaning of this term, one can see how God was preparing His Chosen People for the real Presence of His Son in the Most Blessed Sacrament. The bread offered to Abraham by Melchizedek as a gesture of blessing, the manna in the desert as bread from heaven, the bread of Presence in the tent of meeting and in the Jerusalem temple as a unique manifestation of God’s Covenant and love for His People, as well as the messianic expectations of Jewish tradition are all realities expressing the unfolding plan of God in reference to the Body of Christ, present in the Eucharist. This plan reached its climax during the Last Supper in view of the future ultimate Sacrifice of the Lord on the Cross.

  10. Why are some STEM fields more gender balanced than others?

    Science.gov (United States)

    Cheryan, Sapna; Ziegler, Sianna A; Montoya, Amanda K; Jiang, Lily

    2017-01-01

    Women obtain more than half of U.S. undergraduate degrees in biology, chemistry, and mathematics, yet they earn less than 20% of computer science, engineering, and physics undergraduate degrees (National Science Foundation, 2014a). Gender differences in interest in computer science, engineering, and physics appear even before college. Why are women represented in some science, technology, engineering, and mathematics (STEM) fields more than others? We conduct a critical review of the most commonly cited factors explaining gender disparities in STEM participation and investigate whether these factors explain differential gender participation across STEM fields. Math performance and discrimination influence who enters STEM, but there is little evidence to date that these factors explain why women's underrepresentation is relatively worse in some STEM fields. We introduce a model with three overarching factors to explain the larger gender gaps in participation in computer science, engineering, and physics than in biology, chemistry, and mathematics: (a) masculine cultures that signal a lower sense of belonging to women than men, (b) a lack of sufficient early experience with computer science, engineering, and physics, and (c) gender gaps in self-efficacy. Efforts to increase women's participation in computer science, engineering, and physics may benefit from changing masculine cultures and providing students with early experiences that signal equally to both girls and boys that they belong and can succeed in these fields.

    2016-05-01

    Over the past decades, personality and social psychologists have extensively investigated the role of self-views in individual functioning. Research on world views, however, has been less well studied due to overly specific conceptualizations, and little research about how and why they impact life outcomes. To answer why and how world views matter, we conducted 7 studies to examine the functions, antecedents, and consequences of generalized beliefs about the world, operationalized as social axioms (Leung et al., 2002). This research focused on 2 axiom factors, namely, social cynicism and reward for application. These axioms were found to explain individual differences in self-views over and above personality traits in Hong Kong and U.S. samples (Study 1) and to explain cultural differences in self-views in addition to self-construals among Mainland Chinese, Hong Kong Chinese, East Asian Canadians, and European Canadians (Study 2). Endorsement of social axioms by participants, their parents, and close friends was collected from Mainland China, Hong Kong, and Canada to infer parental and peer influences on world views (Study 3). World views affected psychological well-being through the mediation of positive self-views across 3 age groups, including children, adolescents, and young adults (Study 4) and over time (Study 5). The mediation of negative self-views was through comparative self-criticism rather than internalized self-criticism (Study 6). Holistic thinking moderated the effect of social cynicism on self-views and psychological well-being (Study 7). These results converge to show that world views as a distal force and self-views as a proximal force matter in people's subjective evaluation of their lives.

  18. Why Weight? An Analytic Review of Obesity Management, Diabetes Prevention, and Cardiovascular Risk Reduction.

    Science.gov (United States)

    Igel, L I; Saunders, K H; Fins, J J

    2018-05-21

    In this review, we examine one of the ironies of American health care-that we pay more for disease management than disease prevention. Instead of preventing type 2 diabetes (T2DM) by treating its precursor, obesity, we fail to provide sufficient insurance coverage for weight management only to fund the more costly burden of overt T2DM. There is a vital need for expanded insurance coverage to help foster a weight-centric approach to T2DM management. This includes broader coverage of anti-diabetic medications with evidence of cardiovascular risk reduction and mortality benefit, anti-obesity pharmacotherapy, bariatric surgery, weight loss devices, endoscopic bariatric therapies, and lifestyle interventions for the treatment of obesity. The fundamental question to ask is why weight? Why wait to go after obesity until its end-stage sequelae cause intractable conditions? Instead of managing the complications of T2DM, consider preventing them by tackling obesity.

  19. Why is the teen birth rate in the United States so high and why does it matter?

    Science.gov (United States)

    Kearney, Melissa S; Levine, Phillip B

    2012-01-01

    Teens in the United States are far more likely to give birth than in any other industrialized country in the world. U.S. teens are two and a half times as likely to give birth as compared to teens in Canada, around four times as likely as teens in Germany or Norway, and almost 10 times as likely as teens in Switzerland. Among more developed countries, Russia has the next highest teen birth rate after the United States, but an American teenage girl is still around 25 percent more likely to give birth than her counterpart in Russia. Moreover, these statistics incorporate the almost 40 percent fall in the teen birth rate that the United States has experienced over the past two decades. Differences across U.S. states are quite dramatic as well. A teenage girl in Mississippi is four times more likely to give birth than a teenage girl in New Hampshire--and 15 times more likely to give birth as a teen compared to a teenage girl in Switzerland. This paper has two overarching goals: understanding why the teen birth rate is so high in the United States and understanding why it matters. Thus, we begin by examining multiple sources of data to put current rates of teen childbearing into the perspective of cross-country comparisons and recent historical context. We examine teen birth rates alongside pregnancy, abortion, and "shotgun" marriage rates as well as the antecedent behaviors of sexual activity and contraceptive use. We seek insights as to why the rate of teen childbearing is so unusually high in the United States as a whole, and in some U.S. states in particular. We argue that explanations that economists have tended to study are unable to account for any sizable share of the variation in teen childbearing rates across place. We describe some recent empirical work demonstrating that variation in income inequality across U.S. states and developed countries can explain a sizable share of the geographic variation in teen childbearing. To the extent that income inequality

    Helmet-Mounted Display (HMD) technologies have been developing for over 3 decades and have been studied for multiple applications ranging from military aircraft, to virtual reality, augmented reality, entertainment and a host of other ideas. It would not be unreasonable to assume that after this much time they would be employed in our daily lives as ubiquitously as the common desktop monitor. However, this is simply not the case. How can this be when they can be used in so many ways for so many tasks? Throughout this work we will look at some of the reasons why as well of some of the ways they can be used.

    This study explored why nurses chose to remain in the Western Australian workforce and to develop insights into the role of resilience of nurses and to identify the key characteristics of resilience displayed by these nurses. Nursing is a stressful profession. Prolific quantitative research which measures job stress and resilience has been implemented; however, there is a dearth of qualitative studies which hear the personal narratives as to why nurses remain and thrive in a stressful workplace. Vignettes of nursing resilience reveal underlying themes of resilience where personal stories and events are presented as narrative. Portraiture recognises the inherent value of the nurses' stories giving attention to the nature of their resilience. Interpretation illuminates the portraits or verbal canvasses of the told experience, reflecting success and positivity despite disarray in healthcare settings. Eight themes were identified. The portraits highlight a sometimes imperceptible theme of resilience within nursing. Nurses are resilient; they rely on the social support of colleagues, family and friends to continue to bear their mantle of responsibility. They take pride in their work and accomplishments and give to others altruistically. They laugh, they love nursing and they keep the needs of their patients, clients, residents or students foremost. This paper describes the hallmarks of resilience demonstrated by nurses. Resilience and its relationship to coping in times of adversity are captured within the portraits presented.

  11. Drink driving - Why risk the consequences?

    CERN Multimedia

    2004-01-01

    In the second of the series of articles about alcohol, CERN is highlighting the dangers of drinking and driving. Have you ever driven after drinking alcohol? If you did, then you were more likely to be involved in an accident that could kill or injure yourself or other people. Why risk it? Any alcohol can impair driving ability. The risk of being in an accident rises significantly after alcohol is consumed: at the French legal limit of 0.5 grams of alcohol per litre of blood, a driver is twice as likely to have an accident as someone who has had no alcohol. At the Swiss legal limit of 0.8 g/l, a driver is five times more likely to be involved in an accident. Many EU countries share the French limit. Penalties for breaking the law vary depending on the severity of the offence, but they include disqualification, fines and imprisonment. Drink Drive Limits and Penalties in the European Union Country Limit g/l Prison Sentence (maximum) Austria 0,5 up to 3 months / 3 years (if fatal) Belgiu...

  12. The new statistics: why and how.

    Cumming, Geoff

    2014-01-01

    We need to make substantial changes to how we conduct research. First, in response to heightened concern that our published research literature is incomplete and untrustworthy, we need new requirements to ensure research integrity. These include prespecification of studies whenever possible, avoidance of selection and other inappropriate data-analytic practices, complete reporting, and encouragement of replication. Second, in response to renewed recognition of the severe flaws of null-hypothesis significance testing (NHST), we need to shift from reliance on NHST to estimation and other preferred techniques. The new statistics refers to recommended practices, including estimation based on effect sizes, confidence intervals, and meta-analysis. The techniques are not new, but adopting them widely would be new for many researchers, as well as highly beneficial. This article explains why the new statistics are important and offers guidance for their use. It describes an eight-step new-statistics strategy for research with integrity, which starts with formulation of research questions in estimation terms, has no place for NHST, and is aimed at building a cumulative quantitative discipline.

  13. Why and How Teachers Transform Their Instruction

    Science.gov (United States)

    Light, Barbara J.

    In his 2011 book The highly qualified teacher: What is teacher quality and how do we measure it? Strong argues that as a profession, education has struggled to measure teacher quality and therefore cannot provide a proven system to consistently develop high-quality teachers. In order to move toward an operational definition of teacher quality, Kennedy, in her 2008 journal article entitled "Contributions of qualitative research to research on teacher qualifications" suggests that the causal mechanisms of the development of teachers who are identified as high-quality teachers must be researched, documented, and then used in teacher preparation and development. Instructional ability is a key component of teacher effectiveness. This case study examines instructional transformations made by four teachers to explore why and how teachers make transformations in their teaching. The overarching conclusion of the study is the importance of student-centeredness as a component of teacher effectiveness.

  14. Why doctors should care about animal cruelty.

    Science.gov (United States)

    Sherley, Miranda

    2007-01-01

    Animal cruelty is a significant problem for society, and there are good reasons why doctors should be particularly concerned by it. Increasing evidence for links between animal cruelty and child or spousal abuse is an area of growing concern internationally and of real importance to health professionals. This article aims to raise awareness of the relevance of animal cruelty to medical practice. The links between animal cruelty and human health are discussed broadly and some wider ethical issues raised. Animal cruelty impacts on human health in disparate ways: intentional and unintentional acts of cruelty may reflect underlying mental health problems that need to be addressed. Cruelty within the family setting is an important sentinel for domestic violence and should prompt an assessment for possible child abuse. Furthermore, animal cruelty raises important questions about the nature of empathy, and the type of society that we wish to live in.

  1. 13 reasons why the brain is susceptible to oxidative stress

    Directory of Open Access Journals (Sweden)

    James Nathan Cobley

    2018-05-01

    Full Text Available The human brain consumes 20% of the total basal oxygen (O2 budget to support ATP intensive neuronal activity. Without sufficient O2 to support ATP demands, neuronal activity fails, such that, even transient ischemia is neurodegenerative. While the essentiality of O2 to brain function is clear, how oxidative stress causes neurodegeneration is ambiguous. Ambiguity exists because many of the reasons why the brain is susceptible to oxidative stress remain obscure. Many are erroneously understood as the deleterious result of adventitious O2 derived free radical and non-radical species generation. To understand how many reasons underpin oxidative stress, one must first re-cast free radical and non-radical species in a positive light because their deliberate generation enables the brain to achieve critical functions (e.g. synaptic plasticity through redox signalling (i.e. positive functionality. Using free radicals and non-radical derivatives to signal sensitises the brain to oxidative stress when redox signalling goes awry (i.e. negative functionality. To advance mechanistic understanding, we rationalise 13 reasons why the brain is susceptible to oxidative stress. Key reasons include inter alia unsaturated lipid enrichment, mitochondria, calcium, glutamate, modest antioxidant defence, redox active transition metals and neurotransmitter auto-oxidation. We review RNA oxidation as an underappreciated cause of oxidative stress. The complex interplay between each reason dictates neuronal susceptibility to oxidative stress in a dynamic context and neural identity dependent manner. Our discourse sets the stage for investigators to interrogate the biochemical basis of oxidative stress in the brain in health and disease.

  2. Why Meillassoux’s Speculative Materialism Struggles with Ancestrality

    Directory of Open Access Journals (Sweden)

    Ciprian Jeler

    2014-12-01

    Full Text Available This paper shows that Quentin Meillassoux’s speculative materialism doesn’t offer us the means to account for the ancestral statements that the modern sciences produce, i.e. for the scientific statements about events preceding all forms of life. An analysis of the reasons why Meillassoux thinks that the problem of ancestrality problematizes the contemporary self-evidence of correlationism is first offered. The results of this analysis are then applied to speculative materialism itself and the consequences are not very promising: very much like correlationism, speculative materialism explicitly denies what I call the “generalized version of the realistic assumption of science” and, in so doing, renders scientific ancestral statements de jure unverifiable. Therefore, if correlationism is rendered suspicious by the issue of ancestrality, the same can be said of speculative materialism.

    2011-12-01

    Full Text Available The aim of this paper is to analyse the Icelandic public sector pension system enjoying a third party guarantee. Defined benefit funds fundamentally differ from defined contribution pension funds without a third party guarantee as is the case with the Icelandic general labour market pension funds. We probe the special nature of the public sector pension funds and make a comparison to the defined contribution pension funds of the general labour market. We explore the financial and economic effects of the third party guarantee of the funds, their investment performance and other relevant factors. We seek an answer to the question why time is running out for the country’s largest pension fund that currently faces the prospect of becoming empty by the year 2022.

  4. Why are product prices in online markets not converging?

    Directory of Open Access Journals (Sweden)

    Takayuki Mizuno

    Full Text Available Why are product prices in online markets dispersed in spite of very small search costs? To address this question, we construct a unique dataset from a Japanese price comparison site, which records price quotes offered by e-retailers as well as customers' clicks on products, which occur when they proceed to purchase the product. The novelty of our approach is that we seek to extract useful information on the source of price dispersion from the shape of price distributions rather than focusing merely on the standard deviation or the coefficient of variation of prices, as previous studies have done. We find that the distribution of prices retailers quote for a particular product at a particular point in time (divided by the lowest price follows an exponential distribution, showing the presence of substantial price dispersion. For example, 20 percent of all retailers quote prices that are more than 50 percent higher than the lowest price. Next, comparing the probability that customers click on a retailer with a particular rank and the probability that retailers post prices at a particular rank, we show that both decline exponentially with price rank and that the exponents associated with the probabilities are quite close. This suggests that the reason why some retailers set prices at a level substantially higher than the lowest price is that they know that some customers will choose them even at that high price. Based on these findings, we hypothesize that price dispersion in online markets stems from heterogeneity in customers' preferences over retailers; that is, customers choose a set of candidate retailers based on their preferences, which are heterogeneous across customers, and then pick a particular retailer among the candidates based on the price ranking.

  9. Sympatric Speciation in Threespine Stickleback: Why Not?

    Directory of Open Access Journals (Sweden)

    Daniel I. Bolnick

    2011-01-01

    Full Text Available Numerous theoretical models suggest that sympatric speciation is possible when frequency-dependent interactions such as intraspecific competition drive disruptive selection on a trait that is also subject to assortative mating. Here, I review recent evidence that both conditions are met in lake populations of threespine stickleback (Gasterosteus aculeatus. Nonetheless, sympatric speciation appears to be rare or absent in stickleback. If stickleback qualitatively fit the theoretical requirements for sympatric speciation, why do they not undergo sympatric speciation? I present simulations showing that disruptive selection and assortative mating in stickleback, though present, are too weak to drive speciation. Furthermore, I summarize empirical evidence that disruptive selection in stickleback drives other forms of evolutionary diversification (plasticity, increased trait variance, and sexual dimorphism instead of speciation. In conclusion, core assumptions of sympatric speciation theory seem to be qualitatively reasonable for stickleback, but speciation may nevertheless fail because of (i quantitative mismatches with theory and (ii alternative evolutionary outcomes.

  10. When and Why Did Brains Break Symmetry?

    Directory of Open Access Journals (Sweden)

    Lesley J. Rogers

    2015-12-01

    Full Text Available Asymmetry of brain function is known to be widespread amongst vertebrates, and it seems to have appeared very early in their evolution. In fact, recent evidence of functional asymmetry in invertebrates suggests that even small brains benefit from the allocation of different functions to the left and right sides. This paper discusses the differing functions of the left and right sides of the brain, including the roles of the left and right antennae of bees (several species in both short- and long-term recall of olfactory memories and in social behaviour. It considers the likely advantages of functional asymmetry in small and large brains and whether functional asymmetry in vertebrates and invertebrates is analogous or homologous. Neural or cognitive capacity can be enhanced both by the evolution of a larger brain and by lateralization of brain function: a possible reason why both processes occur side-by-side is offered.

  11. Why are there no great women chefs?

    Science.gov (United States)

    Druckman, Charlotte

    2010-01-01

    This article applies the rhetorical and deliberately provocative approach of the watershed essay art historian Linda Nochlin wrote in 1971—“Why Have there Been No Great Women Artists?”—to today's culinary industry. Nochlin used the question her title posed as a theoretical trap that would draw attention not only to the inherent sexism or prejudice that pervades the way the public perceives art, but also to those same issues' existence within and impact on academia and the other cultural institutions responsible for posing these sorts of questions. Nochlin bypassed the obvious and irrelevant debate over women's being less or differently talented and, in so doing, exposed that debate for being a distraction from the heart of the matter: how, sociologically (media) or institutionally (museums, foundations, etc.), people define a “great artist.” Although it's 40 years later, the polemic is as effective when used to understand the gender divide in the food world.

    2015-01-01

    It is the JME's 40th anniversary and my 20th anniversary working in the field. I reflect on the nature of bioethics and medical ethics. I argue that both bioethics and medical ethics together have, in many ways, failed as fields. My diagnosis is that better philosophy is needed. I give some examples of the importance of philosophy to bioethics. I focus mostly on the failure of ethics in research and organ transplantation, although I also consider genetic selection, enhancement, cloning, futility, disability and other topics. I do not consider any topic comprehensively or systematically or address the many reasonable objections to my arguments. Rather, I seek to illustrate why philosophical analysis and argument remain as important as ever to progress in bioethics and medical ethics. Published by the BMJ Publishing Group Limited.

  16. The EU and ‘Enlargement Fatigue’: Why Has the European Union Not Been Able to Counter ‘Enlargement Fatigue’?

    Directory of Open Access Journals (Sweden)

    Anna Szolucha

    2010-05-01

    Full Text Available This article provides an up-to-date overview of the problems connected with European integration. It focuses on the phenomenon of ‘enlargement fatigue’ and examines its meaning as utilised by the media, EU officials and academics. The article argues that ‘enlargement fatigue’ is not a new concept since the EU has witnessed many 'symptoms' of fatigue at multiple times in its history. The two main arguments that are often presented in order to explain why the EU has not been able to counter ‘enlargement fatigue’, namely the insufficiently tight conditionality applied to prospective members and the EU's crisis of confidence and accountability after the failed attempt to introduce the Constitutional Treaty and prolonged Lisbon Treaty ratification process, are insufficient to explain why fatigue has been so persistent a phenomenon. This article argues that the EU's failure to develop a new vision of the organisation and adjust its structural design accordingly is a reason why the Union has not dealt successfully with fatigue. Such a vision would encompass notions of “variable geometry”, “avant-garde groups” and make European borders flexible and fuzzy.

  20. Survival of the Fittest: Why Terrorist Groups Endure

    Directory of Open Access Journals (Sweden)

    2014-04-01

    Full Text Available Why do terrorist groups endure? This question is relevant to scholars and policy makers alike. In the past, this issue was not been addressed in a systematic fashion. Recent work investigates this question using data on transnational groups and finds that factors associated with the home country can influence the duration the group endures. Applying the theory of outbidding to terrorist group survival, we argue that strategic competition among groups predicts group duration. Using the Global Terrorism Database, we develop a dataset using the terrorist group as the unit of analysis to model the duration of group activity and thus include the largest sample of groups yet. Controlling for previous explanations of both group duration and terrorism, we find a robust effect for the impact that group competition has on terrorist group survival.

  1. Adhesive tape exfoliation: Why it works for graphene

    Bohr, Jakob

    2015-03-01

    Single-crystal graphite can be cleaved by the use of an adhesive tape. This was also the initial route for obtaining graphene, a one-layer thick graphite slab. In this letter a few simple and fun considerations are presented in an attempt to shed some light on why this procedure is successful. In particular on the nature of the surprisingly small number of repetitive steps that are needed in order to obtain a single-layer slab. Two frameworks for exfoliation are investigated: parallel exfoliation involving repetitive simultaneous cleaving, the other, serial exfoliation, which involves the repetitive cleaving of a single chunk of graphite. For both cases, parallel and serial exfoliation, it is investigated how many generations of cleavages are needed. An approximate model with the probability distribution expressed as a simple closed form is presented and compared with the simulations.

  5. Arithmetic groups and their generalizations what, why, and how

    CERN Document Server

    Ji, Lizhen

    2010-01-01

    In one guise or another, many mathematicians are familiar with certain arithmetic groups, such as \\mathbf{Z} or \\mathrm{SL}(n,\\mathbf{Z}). Yet, many applications of arithmetic groups and many connections to other subjects within mathematics are less well known. Indeed, arithmetic groups admit many natural and important generalizations. The purpose of this expository book is to explain, through some brief and informal comments and extensive references, what arithmetic groups and their generalizations are, why they are important to study, and how they can be understood and applied to many fields, such as analysis, geometry, topology, number theory, representation theory, and algebraic geometry. It is hoped that such an overview will shed a light on the important role played by arithmetic groups in modern mathematics.

  6. How (and why) the immune system makes us sleep.

    Science.gov (United States)

    Imeri, Luca; Opp, Mark R

    2009-03-01

    Good sleep is necessary for physical and mental health. For example, sleep loss impairs immune function, and sleep is altered during infection. Immune signalling molecules are present in the healthy brain, where they interact with neurochemical systems to contribute to the regulation of normal sleep. Animal studies have shown that interactions between immune signalling molecules (such as the cytokine interleukin 1) and brain neurochemical systems (such as the serotonin system) are amplified during infection, indicating that these interactions might underlie the changes in sleep that occur during infection. Why should the immune system cause us to sleep differently when we are sick? We propose that the alterations in sleep architecture during infection are exquisitely tailored to support the generation of fever, which in turn imparts survival value.

  7. Darwin's legacy: why biology is not physics, or why evolution has not become a common sense.

    Science.gov (United States)

    Singh, Rama S

    2011-10-01

    Cosmology and evolution together have enabled us to look deep into the past and comprehend evolution-from the big bang to the cosmos, from molecules to humans. Here, I compare the nature of theories in biology and physics and ask why physical theories get accepted by the public without necessarily comprehending them but biological theories do not. Darwin's theory of natural selection, utterly simple in its premises but profound in its consequences, is not accepted widely. Organized religions, and creationists in particularly, have been the major critic of evolution, but not all opposition to evolution comes from organized religions. A great many people, between evolutionary biologists on one hand and creationists on the other, many academics included, who may not be logically opposed to evolution nevertheless do not accept it. This is because the process of and the evidence for evolution are invisible to a nonspecialist, or the theory may look too simple to explain complex traits to some, or because people compare evolution against God and find evolutionary explanations threatening to their beliefs. Considering how evolution affects our lives, including health and the environment to give just two examples, a basic course in evolution should become a required component of all our college and university educational systems.

  9. Theory of Financial Lease Contracts - Why all capital goods are not leased

    OpenAIRE

    Penttinen, Jussi

    2013-01-01

    The economic theory states that the capital structure of a firm is irrelevant in a perfect frictionless world. Hence when the assumptions of the Modigliani–Miller theorem and the CAPM hold, the question about the optimal source of funding of capital investments is also irrelevant. In practice though, capital leasing is widely used and the decision to lease or own assets is hardly a matter of indifference to firms or individuals. The motivation of this thesis is to identify when and why leasin...

    Objective To examine when and why women disbelieve tailored information about their risk of developing breast cancer. Methods 690 women participated in an online program to learn about medications that can reduce the risk of breast cancer. The program presented tailored information about each woman’s personal breast cancer risk. Half of women were told how their risk numbers were calculated, whereas the rest were not. Later, they were asked whether they believed that the program was personalized, and whether they believed their risk numbers. If a woman did not believe her risk numbers, she was asked to explain why. Results Beliefs that the program was personalized were enhanced by explaining the risk calculation methods in more detail. Nonetheless, nearly 20% of women did not believe their personalized risk numbers. The most common reason for rejecting the risk estimate was a belief that it did not fully account for personal and family history. Conclusions The benefits of tailored risk statistics may be attenuated by a tendency for people to be skeptical that these risk estimates apply to them personally. Practice Implications Decision aids may provide risk information that is not accepted by patients, but addressing the patients’ personal circumstances may lead to greater acceptance. PMID:23623330

    Why do so many Southern Californians fail to evacuate when warned that winter storms have critically raised the risk of a debris flow in their neighborhoods? Have they perhaps not seen or heeded news coverage of past debris flow events? Are they unaware that recent fires made the hillsides above them more prone to gravity-driven processes? Do they think they can wait to start their cars until they can actually see the flow coming? Or have they merely experienced too many "false alarms" in past years, and no longer put much stock in the judgment of public officials or the ability of scientists to judge debris flow risk? In preparation for a simulation study that will place decision makers in a virtual house in the California foothills during a winter storm event, we explore the reasons that people do and do not evacuate in the face of potential debris flows. Working in collaboration with the USGS Multi-Hazards Demonstration Project for Southern California, we are surveying hundreds of local residents, from debris-flow prone areas and from elsewhere in the state, to establish their baseline knowledge (and misconceptions) about, attitudes toward, information use regarding, and experience with debris flows. Initial interviews with residents of recently hit neighborhoods give qualitative data suggesting that false-alarm effects and underestimation of risk are driving factors; these surveys will provide quantitative evidence to extend those findings. We will discuss the results of this survey in the context of a comprehensive body of psychology research that seeks to explain why people frequently appear to ignore or discount hazard warnings: neglecting to insure their homes and crops (Kunreuther, 1984), failing to evacuate in the face of storms and fires (Baker, 1991; Packham, 1995), and (barring a recent, vivid event) showing little support for measures that would manage or mitigate future hazards (Kunreuther, 2006a, 2006b; Weber, 2006). We will also consider the

  16. Practice Evaluation Strategies Among Social Workers: Why an Evidence-Informed Dual-Process Theory Still Matters.

    2017-01-01

    Practice evaluation strategies range in style from the formal-analytic tools of single-subject designs, rapid assessment instruments, algorithmic steps in evidence-informed practice, and computer software applications, to the informal-interactive tools of clinical supervision, consultation with colleagues, use of client feedback, and clinical experience. The purpose of this article is to provide practice researchers in social work with an evidence-informed theory that is capable of explaining both how and why social workers use practice evaluation strategies to self-monitor the effectiveness of their interventions in terms of client change. The author delineates the theoretical contours and consequences of what is called dual-process theory. Drawing on evidence-informed advances in the cognitive and social neurosciences, the author identifies among everyday social workers a theoretically stable, informal-interactive tool preference that is a cognitively necessary, sufficient, and stand-alone preference that requires neither the supplementation nor balance of formal-analytic tools. The author's delineation of dual-process theory represents a theoretical contribution in the century-old attempt to understand how and why social workers evaluate their practice the way they do.

It addresses the institutional puzzle of why regions which share so many formal institutions (e.g., Northern and Southern Italy) do diverge so much in quality of government. Similar...... to recent political economy scholarship, our theory points to historical path dependencies. The study argues that a major factor explaining regional path dependencies is the consolidation of clientelistic networks in those regions where rulers have historically (seventeenth to nineteenth centuries) less...

  20. Why does Safety Culture Matter?

    International Nuclear Information System (INIS)

    Dahlgren-Persson, Kerstin

    2008-01-01

    Dr. Kerstin Dahlgren-Persson, from the IAEA presented a plenary paper on 'Why does safety culture matter?'. The paper discussed the main conclusions of a 1998 IAEA conference on shortcomings in safety management. The conference included case studies of TVA, Cooper, Peach Bottom, Millstone, Ontario Hydro, Barsebaeck and Oskarshamn. Common symptoms included insularity; disproportionate focus on technical issues, high initial performance, lack of corporate oversight, changing management direction and cost cutting, repeat problems, and regulatory dissatisfaction. Behind these symptoms was lack of senior utility leadership with the insight, knowledge and ability to manage the unique interaction between the technology, economics, human factors and safety in a changing nuclear environment. Shortcomings relating to the regulator included lack of criteria for when regulatory actions should be taken in response to degradations in safety management, and the inability of some regulators to influence at the senior utility management level. The paper also made the following key points: - Human error is not always symptomatic of a poor safety culture. Effective root cause analysis (such as that carried out for the Columbia accident investigation) is essential to correctly differentiate between situational issues at a point in time and those rooted in organizational culture. - Leaders change culture by holding different assumptions and by making them visible through their words and action. - Regulators should consider how their regulatory strategy influences licensees. For example, a prescriptive strategy can foster a compliance based approach
