    Analyses of the pattern of associations, social interactions, coalitions, and aggression among chacma baboons (Papio hamadryas ursinus) in the Okavango Delta of Botswana over a 16-year period indicate that adult females form close, equitable, supportive, and enduring social relationships. They show strong and stable preferences for close kin, particularly their own mothers and daughters. Females also form strong attachments to unrelated females who are close to their own age and who are likely to be paternal half-sisters. Although absolute rates of aggression among kin are as high as rates of aggression among nonkin, females are more tolerant of close relatives than they are of others with whom they have comparable amounts of contact. These findings complement previous work which indicates that the strength of social bonds enhances the fitness of females in this population and support findings about the structure and function of social bonds in other primate groups.

  3. Update of Earthquake Strong-Motion Instrumentation at Lawrence Livermore National Laboratory

    2013-09-01

    Following the January 1980 earthquake that was felt at Lawrence Livermore National Laboratory (LLNL), a network of strong-motion accelerographs was installed at LLNL. Prior to the 1980 earthquake, there were no accelerographs installed. The ground motion from the 1980 earthquake was estimated from USGS instruments around the Laboratory to be between 0.2 – 0.3 g horizontal peak ground acceleration. These instruments were located at the Veterans Hospital, 5 miles southwest of LLNL, and in San Ramon, about 12 miles west of LLNL. In 2011, the Department of Energy (DOE) requested to know the status of our seismic instruments. We conducted a survey of our instrumentation systems and responded to DOE in a letter. During this survey, it was found that the recorders in Buildings 111 and 332 were not operational. The instruments on Nova had been removed, and only three of the 10 NIF instruments installed in 2005 were operational (two were damaged and five had been removed from operation at the request of the program). After the survey, it was clear that the site seismic instrumentation had degraded substantially and would benefit from an overhaul and more attention to ongoing maintenance. LLNL management decided to update the LLNL seismic instrumentation system. The updated system is documented in this report.

    The paper investigates ethnic minority concentration within social housing and the potentials of a strong social housing sector through an analysis of the housing careers of Somalis and Turks in Copenhagen. In a Danish context, the two ethnic groups differ greatly with respect to migration history...... the social housing sector, which to the interviewees offered good housing options and possibilities for shaping their own housing careers. The majority of the Somalis perceived paying interest as being incompatible with Islam. Renting thus allowed them to adhere to their religious beliefs. The advantages...... of the social housing sector limited the pull of owner-occupied housing. The paper thus questions the use of the home-ownership gap as an indication of a lack of ethnic minority integration....

    2016-01-01

    Detection of influential actors in social media such as Twitter or Facebook plays an important role for improving the quality and efficiency of work and services in many fields such as education and marketing. The work described here aims to introduce a new approach that characterizes the influence of actors by the strength of attracting new active members into a networked community. We present a model of influence of an actor that is based on the attractiveness of the actor in terms of the number of other new actors with which he or she has established relations over time. We have used this concept and measure of influence to determine optimal seeds in a simulation of influence maximization using two empirically collected social networks for the underlying graphs. Our empirical results on the datasets demonstrate that our measure stands out as a useful measure to define the attractors comparing to the other influence measures.

    2008-01-01

    In order to establish the relationships between macroseismic and instrumental parameters, macroseismic field of 28 historical earthquakes that produced great effects in the Colombian territory were studied. The integration of the parameters was made by using the methodology of Kaussel and Ramirez (1992), for great Chilean earthquakes; Kanamori and Anderson (1975) and Coppersmith and Well (1994) for world-wide earthquakes. Once determined the macroseismic and instrumental parameters it was come to establish the model of the source of each earthquake, with which the data base of these parameters was completed. For each earthquake parameters related to the local and normal macroseismic epicenter were complemented, depth of the local and normal center, horizontal extension of both centers, vertical extension of the normal center, model of the source, area of rupture. The obtained empirical relations from linear equations, even show behaviors very similar to the found ones by other authors for other regions of the world and to world-wide level. The results of this work allow establishing that certain mutual non compatibility exists between the area of rupture and the length of rupture determined by the macroseismic methods, with parameters found with instrumental data like seismic moment, Ms magnitude and Mw magnitude.

    Introduction Social exclusion is considered a major factor in the causation and maintenance of health inequalities, but its measurement in health research is still in its infancy. In the Netherlands the Institute for Social Research (SCP) developed an instrument to measure the multidimensional concept of social exclusion in social and economic policy research. Here, we present a method to construct a similar measure of social exclusion using available data from public health surveys. Methods Analyses were performed on data from the health questionnaires that were completed by 20,877 adults in the four largest cities in the Netherlands. From each of the four questionnaires we selected the items that corresponded to those of the SCP-instrument. These were entered into a nonlinear canonical correlation analysis. The measurement properties of the resulting indices and dimension scales were assessed and compared to the SCP-instrument. Results The internal consistency of the indices and most of the dimension scales were adequate and the internal structure of the indices was as expected. Both generalisabiliy and construct validity were good: in all datasets strong associations were found between the index and a number of known risk factors of social exclusion. A limitation of content validity was that the dimension “lack of normative integration” could not be measured, because no relevant items were available. Conclusions Our findings indicate that a measure for social exclusion can be constructed with available health questionnaires. This provides opportunities for application in public health surveillance systems in the Netherlands and elsewhere in the world. PMID:24878842

    Full Text Available The aim of the article is systematization of instruments for implementation of social and economic responsibility of enterprises in Ukraine and theoretical consideration of the presented instruments. The article studies basic views on instruments of social responsibility of business. It is determined which of them are more traditional, and which ones are the latest, that is up to date. Thus, the traditional ones include: philanthropy, charity, sponsorship, volunteering, patronship, monetary grants, equivalent financing. Based on the understanding of the nature of social and economic responsibility of business proposed by the author, to its instruments there can be attributed all traditional instruments, except for volunteering that does not imply obtaining funds for its activities and has only a social effect. There studied modern instruments of business social responsibility, such as social investments, socially responsible investments, social marketing, charity marketing, social programs, social entrepreneurship, social reporting and social expertise, fundraising, socially responsible approaches to doing business and supply chain management. All of them can be regarded as instruments of social and economic responsibility of business.

  19. SOCIAL MEDIA – VITAL INSTRUMENT IN GAINING CONSUMERS CONFIDENCE

    Directory of Open Access Journals (Sweden)

    Mirela-Cristina VOICU

    2016-06-01

    Full Text Available Given that, currently, the consumer has become more demanding and organizations face some of the greatest challenges due to the economic climate of recent years, the need to build and cultivate strong relationships has become vital not only for the company's success but also for its survival. And solid relationships are built over time through confidence. Trust is one of the most important elements in the process of purchasing and consumer loyalty; it is difficult to obtain but easy to lose. Companies that are enjoying a high degree of confidence benefit from best quotations for their shares, higher profits and a better retention of the best employees. The effects of the lack of confidence are obvious (unsatisfied consumers, lost sales and very expensive for the company. In this context, through the following paper we seek to bring more understanding on how a company can gain the confidence of consumers given that the forms of communication that consumers prefer and that are gaining momentum currently, are taking place online, especially in the social media.

    Assessment of social influence on health behavior is often approached through a situational context. The current study adapted an existing, theory-based instrument from another content domain to assess Perceived Social Influence on Health Behavior (PSI-HB) among African Americans, using an individual difference approach. The adapted instrument was found to have high internal reliability (α = .81–.84) and acceptable testretest reliability (r = .68–.85). A measurement model revealed a three-factor structure and supported the theoretical underpinnings. Scores were predictive of health behaviors, particularly among women. Future research using the new instrument may have applied value assessing social influence in the context of health interventions. PMID:20522506

    Although the processes that underlie sharing others' emotions (empathy) and understanding others' mental states (mentalizing, Theory of Mind) have received increasing attention, it is yet unclear how they relate to each other. For instance, are people who strongly empathize with others also more proficient in mentalizing? And (how) do the neural networks supporting empathy and mentalizing interact? Assessing both functions simultaneously in a large sample (N = 178), we show that people's capacities to empathize and mentalize are independent, both on a behavioral and neural level. Thus, strong empathizers are not necessarily proficient mentalizers, arguing against a general capacity of social understanding. Second, we applied dynamic causal modeling to investigate how the neural networks underlying empathy and mentalizing are orchestrated in naturalistic social settings. Results reveal that in highly emotional situations, empathic sharing can inhibit mentalizing-related activity and thereby harm mentalizing performance. Taken together, our findings speak against a unitary construct of social understanding and suggest flexible interplay of distinct social functions. © The Author (2016).

    Evidence suggests that social networks of patients with psychotic disorders influence symptoms, quality of life and treatment outcomes. It is therefore important to assess social networks for which appropriate and preferably established instruments should be used. To identify instruments assessing social networks in studies of patients with psychotic disorders and explore their properties. A systematic search of electronic databases was conducted to identify studies that used a measure of social networks in patients with psychotic disorders. Eight instruments were identified, all of which had been developed before 1991. They have been used in 65 studies (total N of patients = 8,522). They assess one or more aspects of social networks such as their size, structure, dimensionality and quality. Most instruments have various shortcomings, including questionable inter-rater and test-retest reliability. The assessment of social networks in patients with psychotic disorders is characterized by a variety of approaches which may reflect the complexity of the construct. Further research on social networks in patients with psychotic disorders would benefit from advanced and more precise instruments using comparable definitions of and timescales for social networks across studies.

    A proper measurement of the relevant single and two-phase flow parameters is the basis for the understanding of many complex thermal-hydraulic processes. Reliable instrumentation is therefore necessary for the interaction between analysis and experiment especially in the field of nuclear safety research where postulated accident scenarios have to be simulated in experimental facilities and predicted by complex computer code systems. The so-called conventional instrumentation for the measurement of e. g. pressures, temperatures, pressure differences and single phase flow velocities is still a solid basis for the investigation and interpretation of many phenomena and especially for the understanding of the overall system behavior. Measurement data from such instrumentation still serves in many cases as a database for thermal-hydraulic system codes. However some special instrumentation such as online concentration measurement for boric acid in the water phase or for non-condensibles in steam atmosphere as well as flow visualization techniques were further developed and successfully applied during the recent years. Concerning the modeling needs for advanced thermal-hydraulic codes, significant advances have been accomplished in the last few years in the local instrumentation technology for two-phase flow by the application of new sensor techniques, optical or beam methods and electronic technology. This paper will give insight into the current state of instrumentation technology for safety-related thermohydraulic experiments. Advantages and limitations of some measurement processes and systems will be indicated as well as trends and possibilities for further development. Aspects of instrumentation in operating reactors will also be mentioned.

    Breastfeeding provides beneficial health outcomes for infants and their mothers, and increasing its practice is a national priority in many countries. Despite increasing support to exclusively breastfeed, the prevalence at 6 months remains low. Breastfeeding behavior is influenced by a myriad of determinants, including breastfeeding attitudes, knowledge, and social support. Effective measurement of these determinants is critical to provide optimal support for women throughout the breastfeeding period. However, there are a multitude of available instruments measuring these constructs, which makes identification of an appropriate instrument challenging. Research aim: Our aim was to identify and critically examine the existing instruments measuring breastfeeding attitudes, knowledge, and social support. A total of 16 instruments was identified. Each instrument's purpose, theoretical underpinnings, and validity were analyzed. An overview, validation and adaptation for use in other settings was assessed for each instrument. Depth of reporting and validation testing differed greatly between instruments. Content, construct, and predictive validity were present for most but not all scales. When selecting and adapting instruments, attention should be paid to domains within the scale, number of items, and adaptation.

    Full Text Available Education about healthcare is one of the main instruments of the professional work of social assistants in the field of healthcare. It therefore uses ethical-political, theoretical-methodological and technical-operatives, which are dimensions that guide the professional action of social workers and that are essential to a critical understanding of the professional reality and to supporting the intervention of social work. This article raises some elements for the debate about education in health as one of the working instruments of social workers in the field of healthcare. To do so, it addresses the historic trajectory of education in health within Brazilian healthcare policy, highlights the main paradigms that have guided the actions of healthcare in the country and raises some questions for reflection about the ethical-political dimension of education in health as a field of intervention of social workers.

    Full Text Available With its plan to assign 600 million euros through the European Neighbourhood Instrument for Eastern Partnership countries, the European Union intended to increase the efficiency of institutions, attenuate social problems, and create an environment that fosters economic growth and human well-being in Armenia, Azerbaijan, Belarus, Georgia, Moldova, and Ukraine. A few scholars have criticized the amount of funding and planned initiatives of the European Neighbourhood Instrument as insufficient and suggested that in order to foster cooperation and support reforms in its Eastern Partnership countries, more action should be taken. In times when European Commission budget is under constraints of consolidation and increase of aid for supporting European Neighbourhood countries is hardly possible, alternative solutions for tempering social problems need to be assessed. Various scientists, philanthropists and entrepreneurs see social entrepreneurship as a tool for solving social problems in a sustainable way where business thinking is being combined with non-profit philosophy. Contrary to government support and intervention for solving social problems, social entrepreneurship is already being used as tool that initially addresses joint needs--solve social problems and create revenue that provides much needed income for sustainable business initiatives. This paper analyzes the concept of social entrepreneurship, examples where social entrepreneurship is solving social problems, and mechanisms that can foster these phenomena. The aim of this paper is to examine different mechanisms of how governments can foster the creation and development of social entrepreneurship. Unique survey data derived from a project examining social entrepreneurship in Europe is used. It is concluded that by adopting mechanisms proven in various developed countries, the Eastern Partnership countries can stimulate social entrepreneurship, thus attenuating social problems and

    There is growing recognition that in addition to universally recognised domains and indicators of wellbeing (such as population health and life expectancy), additional frameworks are required to fully explain and measure Indigenous wellbeing. In particular, Indigenous Australian wellbeing is largely determined by colonisation, historical trauma, grief, loss, and ongoing social marginalisation. Dominant mainstream indicators of wellbeing based on the biomedical model may therefore be inadequate and not entirely relevant in the Indigenous context. It is possible that "standard" wellbeing instruments fail to adequately assess indicators of health and wellbeing within societies that have a more holistic view of health. The aim of this critical review was to identify, document, and evaluate the use of social and emotional wellbeing measures within the Australian Indigenous community. The instruments were systematically described regarding their intrinsic properties (e.g., generic v. disease-specific, domains assessed, extent of cross-cultural adaptation and psychometric characteristics) and their purpose of utilisation in studies (e.g., study setting, intervention, clinical purpose or survey). We included 33 studies, in which 22 distinct instruments were used. Three major categories of social and emotional wellbeing instruments were identified: unmodified standard instruments (10), cross-culturally adapted standard instruments (6), and Indigenous developed measures (6). Recommendations are made for researchers and practitioners who assess social and emotional wellbeing in Indigenous Australians, which may also be applicable to other minority groups where a more holistic framework of wellbeing is applied. It is advised that standard instruments only be used if they have been subject to a formal cross-cultural adaptation process, and Indigenous developed measures continue to be developed, refined, and validated within a diverse range of research and clinical settings

  4. The Impact of SADC Social Protection Instruments on the Setting Up of a Minimum Social Protection Floor in Southern African Countries

    Full Text Available The Southern African Development Community (SADC was formed to promote the political, economic and social wellbeing of the region. Some of the social objectives of the SADC are the promotion of social development and the alleviation of poverty, the enhancement of the quality of life of the peoples of Southern Africa, and the provision of support to the socially disadvantaged. In order to achieve these objectives, SADC member states have concluded a Treaty and various social protection-related instruments which aim to ensure that everyone in the region is provided with basic minimum social protection. Although the formation of the SADC (and the conclusion of some of its social protection-related instruments preceded both the minimum social protection floor concept and the Social Protection Floor Initiative, the Treaty and instruments can be seen as complying with the requirements of both the concept and the initiative within the region. This article analyses the extent to which the SADC social protection-related instruments fulfil a minimum social floor function at the SADC regional level. The positive and negative aspects of the SADC Treaty and social protection related instruments in this regard are evaluated. In addition, the article reviews the impact of the SADC social protection-related instruments in the setting up of social protection programmes aimed at ensuring a minimum social protection floor in some of the SADC countries. The successes of such country initiatives and the challenges faced are discussed. This is then followed by some concluding observations.

    To investigate whether the Polish Marshal Offices use instruments for social media marketing activities in the field of health promotion. 14 Polish Marshal Offices participated. The Computer-Assisted Web Interview and Computer-Assisted Telephone Interview were used along with a proprietary questionnaire. Standard statistical methods were employed. The number of people using the Internet and social media in Poland is steadily growing. The majority of the offices (93%) performed health promotion activities. The authorities collaborated with other units of local government and non-governmental organizations in these activities. According to respondents, the most convincing form of health promotion is direct communication (46%). More than half of the surveyed offices (56%) did not use portals or social networking sites in health campaigns. The rest of the offices indicated using Facebook (25%) or YouTube (6%). Half of them did not apply the tools of social media marketing. The other half was involved in discussions on health-related online forums (moderation or consulting). Relatively few offices use social media and social media marketing in health promotion campaigns. The use of social media by the Marshal Offices may result in a potential increase in effectiveness of the pro-health campaigns. It is recommended that Polish Marshal Offices recognize the potential benefits of social media marketing campaign instruments in the field of health promotion in order to reach out the digital recipients.

    2009-09-01

    Although strong winds are frequent in Catalonia, one of the events with the strongest impact in recent years was on January 24th 2009. An explosive cyclogenesis process took place in the Atlantic: pressure fell 30 hPa in less than 24 hours. The strong wind storm pounded the northern of Spain and the south of France with some fatalities and important economic losses in these regions. Several automatic weather stations recorded wind gusts higher than 100 km/h in Catalonia. Emergency services received more than 20.000 calls in 24 hours and there were 497 interventions in only 12 hours. As a consequence of fallen and uprooted trees railway and road infrastructures got damages and more than 30.000 customers had no electricity during 24 hours. Unfortunately there were a total of 6 fatalities, two of them because of fallen trees and the other ones when a sports centre collapsed over a group of children. In Spain, insurance policies cover damages due to strong winds when fixed thresholds are overcome and, according to the Royal Decree 300/2004 of 20th February, extraordinary risk are assumed by the Consorcio de Compensación de Seguros. Subsequently, Public Weather Services (PWS) had an increased on the number of requests received from people affected by this event and from insurance companies, for the corresponding indemnity or not. As an example, during the first month after the event, in the Servei Meteorològic de Catalunya (SMC) more than 600 requests were received only related to these damages (as an average PWS of SMC received a total of 400 requests per month). Following the research started by the Social Impact Research Group of MEDEX project, a good vulnerability indicator of a meteorological risk can be the number of requests reported. This study uses the information received in the PWS of the SMC during the six months after the event, according the criteria and methodology established in Gayà et al (2008). The objective is to compare the vulnerability with the

    2011-12-01

    Past research on the associations between area-level/contextual social capital and health has produced conflicting evidence. However, interpreting this rapidly growing literature is difficult because estimates using conventional regression are prone to major sources of bias including residual confounding and reverse causation. Instrumental variable (IV) analysis can reduce such bias. Using data on up to 167,344 adults in 64 nations in the European and World Values Surveys and applying IV and ordinary least squares (OLS) regression, we estimated the contextual effects of country-level social trust on individual self-rated health. We further explored whether these associations varied by gender and individual levels of trust. Using OLS regression, we found higher average country-level trust to be associated with better self-rated health in both women and men. Instrumental variable analysis yielded qualitatively similar results, although the estimates were more than double in size in both sexes when country population density and corruption were used as instruments. The estimated health effects of raising the percentage of a country's population that trusts others by 10 percentage points were at least as large as the estimated health effects of an individual developing trust in others. These findings were robust to alternative model specifications and instruments. Conventional regression and to a lesser extent IV analysis suggested that these associations are more salient in women and in women reporting social trust. In a large cross-national study, our findings, including those using instrumental variables, support the presence of beneficial effects of higher country-level trust on self-rated health. Previous findings for contextual social capital using traditional regression may have underestimated the true associations. Given the close linkages between self-rated health and all-cause mortality, the public health gains from raising social capital within and across

  11. Briefer assessment of social network drinking: A test of the Important People Instrument-5 (IP-5).

    Hallgren, Kevin A; Barnett, Nancy P

    2016-12-01

    The Important People instrument (IP; Longabaugh et al., 2010) is one of the most commonly used measures of social network drinking. Although its reliability and validity are well-supported, the length of the instrument may limit its use in many settings. The present study evaluated whether a briefer, 5-person version of the IP (IP-5) adequately reproduces scores from the full IP. College freshmen (N = 1,053) reported their own past-month drinking, alcohol-related consequences, and information about drinking in their close social networks at baseline and 1 year later. From this we derived network members' drinking frequency, percentage of drinkers, and percentage of heavy drinkers, assessed for up to 10 (full IP) or 5 (IP-5) network members. We first modeled the expected concordance between full-IP scores and scores from simulated shorter IP instruments by sampling smaller subsets of network members from full IP data. Then, using quasi-experimental methods, we administered the full IP and IP-5 and compared the 2 instruments' score distributions and concurrent and year-lagged associations with participants' alcohol consumption and consequences. Most of the full-IP variance was reproduced from simulated shorter versions of the IP (ICCs ≥ 0.80). The full IP and IP-5 yielded similar score distributions, concurrent associations with drinking (r = 0.22 to 0.52), and year-lagged associations with drinking. The IP-5 retains most of the information about social network drinking from the full IP. The shorter instrument may be useful in clinical and research settings that require frequent measure administration, yielding greater temporal resolution for monitoring social network drinking.

  12. Social media as an instrument for organizing mass riots in the United Kingdom in August 2011

    2015-12-01

    Full Text Available Social networks such as Facebook and Twitter have recently become very popular and turned to be an effective instrument for achieving political goals. However, the social networks’ impact is rather ambivalent: on the one hand, social media form specific political actors and support self-organization and civil movements; on the other hand, social media reinforce destructive and aggressive manifestations with the pronounced criminal purposes, e.g. social media ability to disseminate information among large groups is used to organize mass riots. The article analyzes one of the recent and significant events largely provoked by the social networks - mass riots in the United Kingdom in August 2011 that were originally a reaction to the murder of M. Diggan by a police officer who tried to arrest him as a suspect in drug trafficking and possession of weapons. The way events developed into mass riots was the result of discussions in social media and use of social networks to coordinate joint actions of mass riots participants. The article provides a detailed description of the events and authorities’ actions to overcome the crisis and prevent such riots in the future, thus making some conclusions about the nature of social media impact on the politics.

  13. Targeted activation of the hippocampal CA2 area strongly enhances social memory.

    Social cognition enables individuals to understand others' intentions. Social memory is a necessary component of this process, for without it, subsequent encounters are devoid of any historical information. The CA2 area of the hippocampus, particularly the vasopressin 1b receptor (Avpr1b) expressed there, is necessary for memory formation. We used optogenetics to excite vasopressin terminals, originating from the hypothalamic paraventricular nucleus, in the CA2 of mice. This markedly enhanced their social memory if the stimulation occurred during memory acquisition, but not retrieval. This effect was blocked by an Avpr1b antagonist. Finally, this enhanced memory is resistant to the social distraction of an introduced second mouse, important for socially navigating populations of individuals. Our results indicate the CA2 can increase the salience of social signals. Targeted pharmacotherapy with Avpr1b agonists or deep brain stimulation of the CA2 are potential avenues of treatment for those with declining social memory as in various dementias.

We present and then justify through case examples two approaches for assessing social values for ecosystem services using the instrumental paradigm and two approaches using the deliberative paradigm. Each approach makes different assumptions about: the underlying rationale for values assessment......; the process through which values are elicited; the type of representativeness sought, and; the degree of involvement of decision-makers. However, case examples demonstrate that the boundaries between instrumental and deliberative paradigms are often not concrete. To accommodate this fluidity, we offer a third......, pragmatic paradigm that integrates some of the qualities of both. This paradigm has implications for engaging multiple community groups and decision-makers in the articulation and mapping of social values for cultural ecosystem services....

    Behavioral choice can be characterized along two axes. One axis distinguishes reflexive, model-free systems that slowly accumulate values through experience and a model-based system that uses knowledge to reason prospectively. The second axis distinguishes Pavlovian valuation of stimuli from instrumental valuation of actions or stimulus-action pairs. This results in four values and many possible interactions between them, with important consequences for accounts of individual variation. We here explored whether individual variation along one axis was related to individual variation along the other. Specifically, we asked whether individuals' balance between model-based and model-free learning was related to their tendency to show Pavlovian interferences with instrumental decisions. In two independent samples with a total of 243 participants, Pavlovian-instrumental transfer effects were negatively correlated with the strength of model-based reasoning in a two-step task. This suggests a potential common underlying substrate predisposing individuals to both have strong Pavlovian interference and be less model-based and provides a framework within which to interpret the observation of both effects in addiction.

  1. Traditional competitive children's’ games as an instrument of socialization in Tovariševo

    Directory of Open Access Journals (Sweden)

    Krel Aleksandar

    2005-01-01

    Full Text Available Children’s games are one of the key features of childhood. The games help children to develop in physical and mental sense (perception, language, physical development, to express emotions and to fulfill certain important social motives such as needs for socialization, achievements, aggression, love and confirmation. At the same time, the games stand as an important instrument of socialization. A number of the traditional children’s games were never a subject of formal educational program, instead they represent a spontaneous expression in socialization of children. Based on a research in Tovariševo, this paper explores means of socialization among children using competitive games as an example. These games transmit explicit and implicit messages and values of the society to the children and they also help to form and model a child’s personality. In doing so, the games also help to maintain and preserve certain forms and values of the traditional society, which are being implanted from an early age into every individual from the community.

    development of instruments that will favor its early and systematic recognition. The objective of the present study was to identify in the literature indexed from 1999 to July 2004 articles related to psychometric studies on instruments for the assessment of SAD. A systematic search was performed in the PsychoInfo, Lilacs and Medline indexing services using the following key words: social phobia scale, social phobia validity, social phobia reliability and social anxiety scale, with 26 papers being identified. For analysis, the studies were divided into two groups: a Eleven regarding the Liebowitz Social Anxiety Scale (LSAS and b Fifteen regarding other scales already validated or in the process of validation. Among the studies with the LSAS, six worked with the hetero-applied version and four with the self-applied version, identifying satisfactory psychometric qualities regarding validity in the original language (English and in other languages such as French, Hebrew, Turkish and Spanish. In addition, good reliability indices were found, and regarding factorial analysis, the four-factor model was considered to be the most adequate. Among the studies using other scales, eight worked with instruments already validated and seven with new scales, identifying satisfactory values regarding validity and reliability. The main limitations pointed out in the studies surveyed were related to the diversity of the gold standard adopted; sample composition with the absence of clear inclusion and exclusion criteria, and the small number of studies on non-clinical samples, impairing the use of the instruments for general population screening. Future studies are clearly needed to improve the validation of the criterion based on factorial and cluster analysis.

    Population-based data examining the relationship between social participation (SP) and instrumental activities of daily living (IADL) are scarce. This study examined the cross-sectional relationship between SP and IADL in community-dwelling elderly persons. Self-administered questionnaires were mailed to 23 710 residents aged ≥65 years in Nara, Japan (response rate: 74.2%). Data from 14 956 respondents (6935 males and 8021 females) without dependency in basic activities of daily living (ADL) were analyzed. The number, type, and frequency of participation in social groups (SGs) were used to measure SP. SGs included volunteer groups, sports groups, hobby groups, senior citizens' clubs, neighborhood community associations, and cultural groups. IADL was evaluated using the Tokyo Metropolitan Institute of Gerontology Index of Competence. Logistic regression models stratified by gender were used. After adjustment for putative confounding factors, including demographics, health status, life-style habits, ADL, depression, cognitive function, social networks, social support, and social roles, participation in various SGs among both genders was inversely associated with poor IADL, showing a significant dose-response relationship between an increasing number of SGs and a lower proportion of those with poor IADL (P for trend participation and poor IADL was observed for all types of SGs among females, whereas the association was limited to sports groups and senior citizens' clubs among males. Our results show that participation in a variety of SGs is associated with independent IADL among the community-dwelling elderly, regardless of gender. However, the beneficial effects of frequent participation on IADL may be stronger for females than for males.

    Vertical one-dimensional shear wave velocity (Vs) profiles are presented for 25 strong-motion instrument sites along the Mid-Atlantic eastern seaboard, Piedmont region, and Appalachian region, which surround the epicenter of the M5.8 Mineral, Virginia, Earthquake of August 23, 2011. Testing was performed at sites in Pennsylvania, Maryland, West Virginia, Virginia, the District of Columbia, North Carolina, and Tennessee. The purpose of the study is to determine the detailed site velocity profile, the average velocity in the upper 30 meters of the profile (VS,30), the average velocity for the entire profile (VS,Z), and the National Earthquake Hazards Reduction Program (NEHRP) site classification. The Vs profiles are estimated using a non-invasive continuous-sine-wave method for gathering the dispersion characteristics of surface waves. A large trailer-mounted active source was used to shake the ground during the testing and produce the surface waves. Shear wave velocity profiles were inverted from the averaged dispersion curves using three independent methods for comparison, and the root-mean square combined coefficient of variation (COV) of the dispersion and inversion calculations are estimated for each site.

  9. Deep Borehole Instrumentation Along San Francisco Bay Bridges: 1996 - 2003 and Strong Ground Motion Systhesis Along the San Francisco/Oakland Bay Bridge

    As a result of collaboration between the Berkeley Seismographic Station, Lawrence Livermore National Laboratory, and Caltrans, instrument packages have been placed in bedrock in six boreholes and two surface sites along the San Francisco/Oakland Bay Bridge. Since 1996 over 200 local earthquakes have been recorded. Prior to this study few seismic recording instruments existed in bed-rock in San Francisco Bay. We utilized the data to perform analysis of ground motion variability, wave passage, site response, and up-and down-hole wave propagation along the Bay Bridge. We also synthesized strong ground motion at nine locations along the Bay Bridge. Key to these studies is LLNL's effort to exploit the information available in weak ground motions (generally from earthquakes < M=4.0) to enhance predictions of seismic hazards. We found that Yerba Island has no apparent site response at the surface relative to a borehole site. The horizontal to vertical spectral ratio method best revealed no site response, while the complex signal spectral ratio method had the lowest variance for spectral ratios and best predicted surface recordings when the borehole recording was used as input. Both methods identified resonances at about the same frequencies. Regional attenuation results in a significant loss of high frequencies in both surface and borehole recordings. Records are band limited at near 3 Hz. Therefore a traditional rock outcrop site response, flat to high frequency in displacement, is not available. We applied a methodology to predict and synthesize strong ground motion along the San Francisco/Oakland Bay Bridge from a M=7.25 earthquake along the Hayward fault, about12 km distant. We synthesized for three-components and broad-band (0.0-25.0 Hz) ground motion accelerations, velocities, and displacements. We examined two different possible rupture scenarios, a ''mean'' and ''one standard deviation'' model. We combined the high

    Burgdörfer, G; Hautzinger, M

    1987-01-01

    Scales for the measurement of social and physical anhedonia, the lowered ability to experience pleasure, were investigated. Both scales were devised by Chapman et al. German versions of these two patient populations and two groups of normal subjects. The reliability and scale intercorrelation coefficients were acceptable for the scales overall, but not for the separate subscales. Patients scored higher on both scales than normal subjects, and patients with neurotic depression had higher scores than those with a diagnosis of schizophrenia. A significant correlation with a chronic course was identified in the schizophrenic patients. Item analysis and factor analysis did not reveal any significant common dimensions in the 87 items in the original scales. Only 17 items in the physical anhedonia scale and 26 items in the social anhedonia scale met test-theoretical criteria of acceptability for inclusion in a German version of these scales. Discrepancies and congruencies between American and German studies were discussed, as were further criteria that might make it possible to improve research instruments of this kind.

    2018-02-01

    The purpose of this study was to contribute to content validity, by providing input into the linguistic and pragmatic validities, of a 53 item Psychological-Social-Spiritual Healing instrument. Discovery of cultural values and beliefs from African American elders' experiences of illness provides insight for development of more culturally sensitive instruments. Through an exploratory descriptive design, this study used cognitive interviewing methods to examine linguistic and pragmatic validity of the Psychological-Social-Spiritual Healing instrument, from the perspectives of aging seriously ill AAs. Participants were recruited from urban Jackson, MS from community settings from October 2014 to January 2015. With a purposefully chosen sample of seriously ill African Americans elders (N=15), and using the method of cognitive interviewing, responses related to cultural relevance, clarity and meaning of the 53 items of the instrument were collected. This in-depth query of items was accomplished through the use of both verbal probing and think aloud methods of cognitive interviewing. Thirty-seven items were retained. Eight items were revised. Eight items were deleted. From the expert input of seriously ill African American elders, a systematic decision-making process of item retention, revision or deletion led to the development of a more culturally sensitive Psychological-Social-Spiritual Healing instrument.

  1. Use of social networking websites as a care instrument for hospitalized adolescents

    Directory of Open Access Journals (Sweden)

    Camila Amaral Borghi

    2017-12-01

    Full Text Available Abstract Objective: This study aimed to understand how social networking websites are used by adolescents and their importance during the hospitalization process. Method: A descriptive and qualitative study was supported by the virtual ethnographic method and resorted to the symbolic interactionism as theoretical framework. Eleven hospitalized adolescents were interviewed. Results: Three categories were identified based on the analysis of interviews and posts: Being able to use social networking websites during hospitalization; Using the Facebook® chat to keep connected to friends; Seeking support from friends through social networking websites. Final considerations: Facebook® was the social networking website that adolescents used the most, standing out as an important form of entertainment during hospitalization that facilitates communication and social support. Healthcare professionals should value the use of social networking websites by hospitalized adolescents and encourage access to these tools, providing hospital resources to expand and facilitate this access.

    Rothman, Margaret; Gnanaskathy, Ari; Wicks, Paul; Papadopoulos, Elektra J

    2015-01-01

    We report a panel designed to open a dialog between pharmaceutical sponsors, regulatory reviewers, and other stakeholders regarding the use of social media to collect data to support the content validity of patient-reported outcome instruments in the context of medical product labeling. Multiple stakeholder perspectives were brought together to better understand the issues encountered in pursuing social media as a form of data collection to support content validity. Presenters represented a pharmaceutical sponsor of clinical trials, a regulatory reviewer from the Food and Drug Administration, and an online data platform provider. Each presenter shared its perspective on the advantages and disadvantages of using social media to collect this type of information. There was consensus that there is great potential for using social media for this purpose. There remain, however, unanswered questions that need to be addressed such as identifying which type of social media is most appropriate for data collection and ensuring that participants are representative of the target population while maintaining the advantages of anonymity provided by online platforms. The use of social media to collect evidence of content validity holds much promise. Clarification of issues that need to be addressed and accumulation of empirical evidence to address these questions are essential to moving forward.

    Objectives. To develop and validate a scale measuring pharmacy students’ attitudes toward social media professionalism, and assess the impact of an educational presentation on social media professionalism. Methods. A social media professionalism scale was used in a pre- and post-survey to determine the effects of a social media professionalism presentation. The 26-item scale was administered to 197 first-year pharmacy (P1) students during orientation. Exploratory factor analysis was applied to determine the number of underlying factors responsible for covariation of the data. Principal components analysis was used as the extraction method. Varimax was selected as the rotation method. Cronbach’s alpha was estimated. Wilcoxon signed rank test was used to compare pre- and post-scores of each item, subscale, and total scale. Results. There were 187 (95%) students who participated. The final scale had five subscales and 15 items. Subscales were named according to the professionalism tenet they best represented. Scores of items addressing reading/posting to social media during class, an employer’s use of social media when making hiring decisions, and a college/university’s use of social media as a measure of professional conduct significantly increased from pre-test to post-test. The “honesty and integrity” subscale score also significantly increased. Conclusion. The social media professionalism scale measures five tenets of professionalism and exhibits satisfactory reliability. The presentation improved P1 students’ attitudes regarding social media professionalism. PMID:28630506

  5. Electrophysiological responses to alcohol cues are not associated with Pavlovian-to-instrumental transfer in social drinkers.

    Directory of Open Access Journals (Sweden)

    Jasna Martinovic

    Full Text Available Pavlovian to Instrumental Transfer (PIT refers to the behavioral phenomenon of increased instrumental responding for a reinforcer when in the presence of Pavlovian conditioned stimuli that were separately paired with that reinforcer. PIT effects may play an important role in substance use disorders, but little is known about the brain mechanisms that underlie these effects in alcohol consumers. We report behavioral and electroencephalographic (EEG data from a group of social drinkers (n = 31 who performed a PIT task in which they chose between two instrumental responses in pursuit of beer and chocolate reinforcers while their EEG reactivity to beer, chocolate and neutral pictorial cues was recorded. We examined two markers of the motivational salience of the pictures: the P300 and slow wave event-related potentials (ERPs. Results demonstrated a behavioral PIT effect: responding for beer was increased when a beer picture was presented. Analyses of ERP amplitudes demonstrated significantly larger slow potentials evoked by beer cues at various electrode clusters. Contrary to hypotheses, there were no significant correlations between behavioral PIT effects, electrophysiological reactivity to the cues, and individual differences in drinking behaviour. Our findings are the first to demonstrate a PIT effect for beer, accompanied by increased slow potentials in response to beer cues, in social drinkers. The lack of relationship between behavioral and EEG measures, and between these measures and individual differences in drinking behaviour may be attributed to methodological features of the PIT task and to characteristics of our sample.

  8. Putnam’s instrument revisited. The community network of the industrial districts and a new proxy of social capital

    Directory of Open Access Journals (Sweden)

    Luca Andriani

    2015-04-01

    Full Text Available This paper proposes a new proxy of social capital based on the regional density of industrial districts. The advantage of this new proxy is to better deal, at least conceptually, with the main three problems related to the PI advanced by Paldam (2000 which are: the definition of voluntary associations, the intensity of the contacts and the so called “Benignness-weight problem”. In our analysis we show an empirical comparison between the behaviour of our index and that one of the Putnam Instrument across the Italian regions. To do so we use regional data in the 2001 from the Italian National Bureau of Statistics (ISTAT. One of the interesting results from the empirical application is that the new proxy and the Putnam’s instruments present similar patterns, even though with some exceptions.

    Masashige Saito

    2017-05-01

    Full Text Available Background: We developed and validated an instrument to measure community-level social capital based on data derived from older community dwellers in Japan. Methods: We used cross-sectional data from the Japan Gerontological Evaluation Study, a nationwide survey involving 123,760 functionally independent older people nested within 702 communities (i.e., school districts. We conducted exploratory and confirmatory factor analyses on survey items to determine the items in a multi-dimensional scale to measure community social capital. Internal consistency was checked with Cronbach's alpha. Convergent construct validity was assessed via correlating the scale with health outcomes. Results: From 53 candidate variables, 11 community-level variables were extracted: participation in volunteer groups, sports groups, hobby activities, study or cultural groups, and activities for teaching specific skills; trust, norms of reciprocity, and attachment to one's community; received emotional support; provided emotional support; and received instrumental support. Using factor analysis, these variables were determined to belong to three sub-scales: civic participation (eigenvalue = 3.317, α = 0.797, social cohesion (eigenvalue = 2.633, α = 0.853, and reciprocity (eigenvalue = 1.424, α = 0.732. Confirmatory factor analysis indicated the goodness of fit of this model. Multilevel Poisson regression analysis revealed that civic participation score was robustly associated with individual subjective health (Self-Rated Health: prevalence ratio [PR] 0.96; 95% confidence interval [CI], 0.94–0.98; Geriatric Depression Scale [GDS]: PR 0.95; 95% CI, 0.93–0.97. Reciprocity score was also associated with individual GDS (PR 0.98; 95% CI, 0.96–1.00. Social cohesion score was not consistently associated with individual health indicators. Conclusions: Our scale for measuring social capital at the community level might be useful for future studies of older community dwellers.

    2006-01-01

    In this article we take up a critique of the concept of Communities of Practice voiced by several authors, who suggest that network may provide a better metaphor to understand social forms of organisation and learning. This critique we situate within a broader theoretical movement in socio-cultural learning theories. From this we identify some theoretical and analytical challenges to the network metaphor, which we explore and elaborate through an analysis of a Danish social networking site.

    Mutchler, Jan E; Li, Yang; Xu, Ping

    2018-04-16

    Older Americans rely heavily on Social Security benefits (SSBs) to support independent lifestyles, and many have few or no additional sources of income. We establish the extent to which SSBs adequately support economic security, benchmarked by the Elder Economic Security Standard TM Index. We document variability across U.S. counties in the adequacy levels of SSBs among older adults. We find that the average SSB falls short of what is required for economic security in every county in the U.S., but the level of shortfall varies considerably by location. Policy implications relating to strengthening Social Security and other forms of retirement income are discussed.

    2012-06-01

    Full Text Available The paper emphasizes the need for the tourism sector to adopt a policy of social responsibility for building sustainable development, necessary for the socio-economic recovery of Romania. The study includes a sample of 68 hotels in the five counties of South West Oltenia Region. Data for the research was collected by accessing the official websites for each hotel in order to analyze the degree of implementation of social responsibility on the basis of ten variables, required to achieve a sustainable tourism. The findings reveal a lack of transparency and involvement in social responsibility of the hotel industry in South West Oltenia. Research has shown that accomodation and tourism sector in the region analyzed is far from reaching the international standards, so the adoption of recommendations on best practices would be an important step forward for enhancing sustainable tourism in Romania.

    The objective of this study was to investigate the relationship among socioeconomic status, social support, and food insecurity in a rural Kenyan island community. A cross-sectional random sample of 111 female heads of households representing 583 household members were surveyed in Mfangano Island, Kenya from August to October 2010 using adaptations of the Household Food Insecurity Access Scale and the Medical Outcomes Study Social Support Survey. In multiple linear regression models, less instrumental social support, defined as concrete direct ways people help others (B = -0.81; 95% confidence interval [CI] -1.45 to -0.17), and decreased ownership scale based on owning material assets (B = -2.93; 95% CI -4.99 to -0.86) were significantly associated with increased food insecurity, controlling for age, education, marital status, and household size. Social support interventions geared at group capacity and resilience may be crucial adjuncts to improve and maintain the long term food security and health of persons living in low-resource regions.

    2015-01-01

    Michael Nofer examines whether and to what extent Social Media can be used to predict stock returns. Market-relevant information is available on various platforms on the Internet, which largely consist of user generated content. For instance, emotions can be extracted in order to identify the investors' risk appetite and in turn the willingness to invest in stocks. Discussion forums also provide an opportunity to identify opinions on certain companies. Taking Social Media platforms as examples, the author examines the forecasting quality of user generated content on the Internet.

    2009-01-01

    Background: The significance of dreams has been explained in psychoanalysis, depth psychology and gestalt therapy. There are many guidelines in analytic psychology for dream interpretation and integration in clinical practice. The present study, based on the Jungian analytic model, incorporated dreams as an instrument for assessment of aetiology, the psychotherapy process and the outcome of treatment for social phobia within a clinical case study. Method: This case study describes the use of dream analysis in treating a female youth with social phobia. Results: The present findings supported the three stage paradigm efficiency in the Jungian model for dream working within a clinical setting, i.e. written details, reassembly with amplification and assimilation. It was indicated that childhood and infantile traumatic events, psychosexual development malfunctions, and inefficient coping skills for solving current life events were expressed in the patient’s dreams. Conclusion: Dreams can reflect a patient’s aetiology, needs, illness prognosis and psychotherapy outcome. Dreams are an instrument for the diagnosis, research and treatment of mental disturbances in a clinical setting. PMID:22135511

  17. Measuring social science concepts in pharmacy education research: From definition to item analysis of self-report instruments.

    Science.gov (United States)

    Cor, M Ken

    Interpreting results from quantitative research can be difficult when measures of concepts are constructed poorly, something that can limit measurement validity. Social science steps for defining concepts, guidelines for limiting construct-irrelevant variance when writing self-report questions, and techniques for conducting basic item analysis are reviewed to inform the design of instruments to measure social science concepts in pharmacy education research. Based on a review of the literature, four main recommendations emerge: These include: (1) employ a systematic process of conceptualization to derive nominal definitions; (2) write exact and detailed operational definitions for each concept, (3) when creating self-report questionnaires, write statements and select scales to avoid introducing construct-irrelevant variance (CIV); and (4) use basic item analysis results to inform instrument revision. Employing recommendations that emerge from this review will strengthen arguments to support measurement validity which in turn will support the defensibility of study finding interpretations. An example from pharmacy education research is used to contextualize the concepts introduced. Copyright © 2017 Elsevier Inc. All rights reserved.

The present findings supported the three stage paradigm efficiency in the Jungian model for dream working within a clinical setting, i.e. written details, reassembly with amplification and assimilation. It was indicated that childhood and infantile traumatic events, psychosexual development malfunctions, and inefficient coping skills for solving current life events were expressed in the patient's dreams. Dreams can reflect a patient's aetiology, needs, illness prognosis and psychotherapy outcome. Dreams are an instrument for the diagnosis, research and treatment of mental disturbances in a clinical setting.

    To investigate whether social participation (SP) in older adults is associated with ability to perform instrumental activities of daily living (IADLs). Prospective cohort study. Two local municipalities of Nara, Japan. Individuals aged 65 to 96 (n = 2,774 male, n = 3,586 female) free of IADL disability at baseline. SP and IADLs were assessed using self-administered questionnaires. SP was categorized into five types and assessed using the number and type of social activities. IADLs were evaluated using the Tokyo Metropolitan Institute of Gerontology Index of Competence. Logistic regression analysis stratified according to sex was used to examine change in IADLs according to SP, with nonparticipation as a reference. During the 3-year follow-up, 13.6% of men and 9.0% of women reported IADL decline. After adjusting for age, family structure, body mass index, pension, occupation, medical treatment, self-rated health, drinking, smoking, depression, cognitive function, and activities of daily living, participation in various social activities was inversely associated with change in IADLs in women but not men. Participation in the following types of social activities had significant inverse associations with IADL disability: hobby clubs (odds ratio (OR) = 0.68, 95% confidence interval (CI) = 0.49-0.94) for men and local events (OR = 0.68, 95% CI = 0.48-0.95), hobby clubs (OR = 0.53, 95% CI = 0.36-0.79), senior citizen clubs (OR = 0.74, 95% CI = 0.56-0.97), and volunteer groups (OR = 0.56, 95% CI = 0.32-0.99) for women. Participation in a variety of different types of social activities was associated with change in IADLs over the 3 years of this study in women, and participation in hobby clubs was associated with change in IADLs in men and women. Recommending that community-dwelling elderly adults participate in social activities appropriate for their sex may promote successful aging. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics

    Full Text Available Social networks are a significant way through which rural communities that manage resources under common property regimes obtain food resources. Previous research on food security and social network analysis has mostly focused on egocentric network data or proxy variables for social networks to explain how social relations contribute to the different dimensions of food security. Whole-network approaches have the potential to contribute to former studies by revealing how individual social ties aggregate into complex structures that create opportunities or constraints to the sharing and distribution of food resources. We used a whole-network approach to investigate the role of network structure in contributing to the four dimensions of food security: food availability, access, utilization, and stability. For a case study of a riparian community from the Brazilian Amazon that is dependent on fish as a key element of food security, we mapped the community strong-tie network among 97% of the village population over 14 years old (n = 336 by integrating reciprocated friendship and occupational ties, as well as close kinship relationships. We explored how different structural properties of the community network contribute to the understanding of (1 the availability of fish as a community resource, (2 community access to fish as a dietary resource, (3 the utilization of fish for consumption in a way that allows the villagers to maximize nutrition while at the same time minimizing toxic risks associated with mercury exposure, and (4 the stability of the fish resources in local ecosystems as a result of cooperative behaviors and community-based management. The contribution of whole-network approaches to the study of the links between community-based natural resource management and food security were discussed in the context of recent social-ecological changes in the Amazonian region.

    This article describes the development and validation of an instrument that can be used to assess students' perceptions of their learning environment as a means of monitoring and guiding changes toward social constructivist learning environments. The study used a mixed-method approach with priority given to the quantitative data collection. During the quantitative data collection phase, a new instrument—the Social Constructivist Learning Environment Survey (SCLES)—was developed and used to collect data from 1,955 grade 9 science students from 52 classes in 50 schools in the Western Cape province, South Africa. The data were analysed to evaluate the reliability and validity of the new instrument, which assessed six dimensions of the classroom learning environment, namely, Working with Ideas, Personal Relevance, Collaboration, Critical Voice, Uncertainty in Science and Respect for Difference. Two dimensions were developed specifically for the present study in order to contextualise the questionnaire to the requirements of the new South African curriculum (namely, Metacognition and Respect for Difference). In the qualitative data collection phase, two case studies were used to investigate whether profiles of class mean scores on the new instrument could provide an accurate and "trustworthy" description of the learning environment of individual science classes. The study makes significant contributions to the field of learning environments in that it is one of the first major studies of its kind in South Africa with a focus on social constructivism and because the instrument developed captures important aspects of the learning environment associated with social constructivism.

    The purpose of this paper is to investigate the effect of social trust on the willingness to pay more taxes to improve public healthcare in post-communist countries. The well-documented association between higher levels of social trust and better health has traditionally been assumed to reflect the notion that social trust is positively associated with support for public healthcare system through its encouragement of cooperative behaviour, social cohesion, social solidarity, and collective action. Hence, in this paper, we have explicitly tested the notion that social trust contributes to an increase in willingness to financially support public healthcare. We use micro data from the 2010 Life-in-Transition survey (N = 29,526). Classic binomial probit and instrumental variables ivprobit regressions are estimated to model the relationship between social trust and paying more taxes to improve public healthcare. We found that an increase in social trust is associated with a greater willingness to pay more taxes to improve public healthcare. From the perspective of policy-making, healthcare administrators, policy-makers, and international donors should be aware that social trust is an important factor in determining the willingness of the population to provide much-needed financial resources to supporting public healthcare. From a theoretical perspective, we found that estimating the effect of trust on support for healthcare without taking confounding and measurement error problems into consideration will likely lead to an underestimation of the true effect of trust.

    People with spinal cord injury (SCI) are more susceptible to sedentary lifestyles because of the displacement of physical functioning and the copious barriers. Benefits of physical activity for people with SCI include physical fitness, functional capacity, social integration and psychological well-being. The purpose of this study was to develop and test a social cognitive theory-based instrument aimed to predict physical activity among people with SCI. An instrument was developed through the utilization and modification of previous items from the literature, an expert panel review, and cognitive interviewing, and tested among a sample of the SCI population using a cross-sectional design. Statistical analysis included descriptives, correlations, multiple regression, and exploratory factor analysis. The physical activity outcome variable was significantly and positively correlated with self-regulatory efficacy (r = 0.575), task self-efficacy (r = 0.491), self-regulation (r = 0.432), social support (r = 0.284), and outcome expectations (r = 0.247). Internal consistency for the constructs ranged from 0.82 to 0.96. Construct reliability values for the self-regulation (0.95), self-regulatory efficacy (0.96), task self-efficacy (0.94), social support (0.84), and outcome expectations (0.92) each exceeded the 0.70 a priori criteria. The factor analysis was conducted to seek modifications of current instrument to improve validity and reliability. The data provided support for the convergent validity of the five-factor SCT model. This study provides direction for further development of a valid and reliable instrument for predicting physical activity among people with SCI. Copyright © 2017 Elsevier Inc. All rights reserved.

    Population and family planning activities first came into being in Vietnam in 1963 after a decree on fertility control was issued by the Council of Government on December 26, 1961. The Ministry of Health (MOH) was in charge of such activities, using its own network to provide services and mass organizations to garner public support for the acceptance of family planning. On May 13, 1979, the council transferred family planning activities to the new Committee for Maternal and Child Protection. However, that committee was soon disbanded, and family planning activities were returned to the auspices of the MOH. The National Committee for Population and Family Planning was created in 1984 under the MOH with the goal of mobilizing all social forces in population and family planning activities. Decrees of October 1988 and March 1989, and in 1991 and 1993, strengthened measures to reduce population growth and ensure that adequate family planning methods were available to couples. Vietnam's Population and Family Planning Program has strong political support. Indeed, the government of Vietnam has invested almost 30% of its budget into education, health, and population and family planning programs.

Before-and-after study design, following a practice intervention to screen all youth in foster care for psychosocial problems using the Strengths and Difficulties Questionnaire (SDQ), a validated instrument with 5 subdomains. After implementation of systematic screening, youth aged 11 to 17 years and their foster parents completed the SDQ at routine health maintenance visits. We assessed feasibility of screening by measuring the completion rates of SDQ by youth and foster parents. We compared the detection of psychosocial problems during a 2-year period before systematic screening to the detection after implementation of systematic screening with the SDQ. We used chart reviews to assess detection at baseline and after implementing systematic screening. Altogether, 92% of 212 youth with routine visits that occurred after initiation of screening had a completed SDQ in the medical record, demonstrating high feasibility of systematic screening. Detection of a potential mental health problem was higher in the screening period than baseline period for the entire population (54% vs 27%, P problem domains on the SDQ. Systematic screening for potential social-emotional problems among youth in foster care was feasible within a primary care setting and doubled the detection rate of potential psychosocial problems.

Study 2 (N = 384 further corroborated the findings from Study 1 by showing that when controlling for the physical symptoms experienced prior to the daily diary reports, the level of loneliness experienced over a 13-day period exacerbates the age differences in the physical symptoms. The present study thus provides converging evidence that social relatedness plays a significant role in physical health, particularly in the older population.

    The efficacy of promoting social interactions to improve the health of older adults is not fully established due to residual confounding and selection bias. The government of Taketoyo town, Aichi Prefecture, Japan, developed a resident-centred community intervention programme called 'community salons', providing opportunities for social interactions among local older residents. To evaluate the impact of the programme, we conducted questionnaire surveys for all older residents of Taketoyo. We carried out a baseline survey in July 2006 (prior to the introduction of the programme) and assessed the onset of functional disability during March 2012. We analysed the data of 2421 older people. In addition to the standard Cox proportional hazard regression, we conducted Cox regression with propensity score matching (PSM) and an instrumental variable (IV) analysis, using the number of community salons within a radius of 350 m from the participant's home as an instrument. In the 5 years after the first salon was launched, the salon participants showed a 6.3% lower incidence of functional disability compared with non-participants. Even adjusting for sex, age, equivalent income, educational attainment, higher level activities of daily living and depression, the Cox adjusted HR for becoming disabled was 0.49 (95% CI 0.33 to 0.72). Similar results were observed using PSM (HR 0.52, 95% CI 0.33 to 0.83) and IV-Cox analysis (HR 0.50, 95% CI 0.34 to 0.74). A community health promotion programme focused on increasing social interactions among older adults may be effective in preventing the onset of disability.

  6. The Role that Religious Festivities Have in Society and Ideology: Local Identity, Social Control and Instrument of Domination

    Directory of Open Access Journals (Sweden)

    José Fernando Domene Verdú

    2017-08-01

    Full Text Available This article attempts to answer the question: what role have religious and patroness festivities in society, now and throughout history? They belong to what is called popular religiosity, are utilitarian —because they were used as a solution to natural and epidemic calamities— and are mainly a symbol of local or regional identity. But besides this, they have always had a social and ideological role, which can be summarized as maintaining the established social order, mainly by making that a part of the population identifies itself with the Crown and the ruling aristocracy. The parallel between God, the Virgin and the saints with the kings, feudal lords and members of the nobility in general favored that the same attitudes of obedience and submission that common people had toward the religious figures, they also had them to the social ruling figures (the nobility, the clergy and the subsequent absolute monarchy. Therefore, religious festivities (Easter, Christmas, Kings and, especially, the patron-saints’ festivities were the most suitable cultural event to promote that the common people adopt these attitudes towards religious figures and, indirectly, also towards the civilian ones.

    PURPOSE of this study was to investigate the psychometric properties of the newly adapted German Version of the Social Impact Scale (SIS), a multidimensional questionnaire measuring perceived stigmatization. The SIS was translated into the German language following state-of-the-art criteria and completed in a sample of 139 outpatients with mixed tumor entities. In addition to the SIS-D, participants answered questions about their experience of discrimination and perceived visibility of their disease as well as about illness beliefs and perceptions of cancer control. Comparably to the original scale, exploratory factor analysis resulted in a 4-factor solution and the following dimensions: "social isolation" (Cronbachs α=0.89), "social rejection" (α=0.81), "internalized shame" (α=0.81) and "financial insecurity" (α=0.81). Considering the results of this pilot study, it can be concluded that the German version of the SIS is an instrument measuring perceived stigmatization in cancer patients with very good psychometric properties. However, further validation studies are considered necessary. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available Sustainability and social responsibility (SR have emerged as a new way of managing all types of organizations. It is necessary that the resulting policy be integrated transversely in the control processes. The environment is especially demanding of higher education institutions (HEIs and universities when it comes to behaving in a socially responsible manner due to their great influence in society. Many universities have adhered to the United Nations Global Compact (UNGC principles to prove their commitment and gain legitimacy. The Communication on Progress (COP is a management tool that helps to understand the level of implementation of the principles. Furthermore, COP analysis aids in establishing a process of continuous improvement in the management of the impacts that institutions have on their stakeholders. The aim of this study was to analyze the Spanish universities that have joined the Global Compact. Through a descriptive methodology, we identified the aspects that reflect this commitment and how this is integrated into their operational and educational processes. The results have shown that it is necessary to promote the integration of different international initiatives to guide the SR of universities. There are deficiencies in their SR management systems that prevent them from being more transparent, and it was found that in some cases, they are not aware of the implications the commitment can have in developed countries.

  11. A Critical Investigation of the Relevance and Potential of IDPS as a Local Governance Instrument for Pursuing Social Justice in South Africa

    2013-12-01

    Full Text Available Unlike the situation in the past, when local government’s role was limited to service delivery, local government is now constitutionally mandated to play an expanded developmental role. As a “co-responsible” sphere of government, local government is obliged to contribute towards realising the transformative constitutional mandate aimed at social justice. South African scholars and jurists share the view that social justice is primarily concerned with the eradication of poverty and extreme inequalities in access to basic services, and aims to ensure that poor people command sufficient material resources to facilitate their equal participation in socio-political life. In order to enable municipalities to fulfil their broad constitutional mandate, the system of integrated development planning (IDPs came into effect in South Africa in 2000. Each municipality is obliged to design, adopt and implement an integrated development plan in order to achieve its expanded constitutional mandate. The IDP is considered to be the chief legally prescribed governance instrument for South African municipalities. The purpose of this article is to explore and critically investigate the relevance and potential of IDPs in contributing towards the achievement of social justice in South Africa. This article argues inter alia that the multitude of sectors that converge in an IDP makes it directly relevant and gives it enormous potential to contribute towards social justice because, depending on the context, municipalities could include and implement strategies that specifically respond to diverse areas of human need. In this regard, the legal and policy frameworks for IDPs provide a structured scheme that could be used by municipalities to prioritise and meet the basic needs of especially the poor. Despite its potential, it is argued that the ability of IDPs to respond to the basic needs of the poor is largely constrained by a series of implementation challenges

    To investigate whether fruit and vegetable (F&V) intake in 11-year-olds, and social-environmental correlates of F&V intake such as parental modelling and encouragement, family food rules and home availability, differ according to general parenting styles in Belgium, The Netherlands, Portugal and Spain. Cross-sectional study. Primary schools in four countries. Pupils and one of their parents completed questionnaires to measure F&V intake, related social-environmental correlates and general parenting styles. The sample size was 4555 (49.3 % boys); 1180 for Belgium, 883 for The Netherlands, 1515 for Portugal and 977 for Spain. Parenting styles were divided into authoritative, authoritarian, indulgent and neglectful. No differences were found in F&V intake across parenting styles and only very few significant differences in social-environmental correlates. The authoritarian (more parental encouragement and more demands to eat fruit) and the authoritative (more availability of fruit and vegetables) parenting styles resulted in more favourable correlates. Despite earlier studies suggesting that general parenting styles are associated with health behaviours in children, the present study suggests that this association is weak to non-existent for F&V intakes in four different European countries.

  13. PROPOSAL OF THE SOCIAL CONTRACT IN MANAGEMENT AS INSTRUMENT OF ANALYSIS FOR THE EMPLOYMENT RELATION. THE EXPERIENCE OF AUTOMOTIVE INDUSTRY IN ROMANIA

    2012-07-01

    Full Text Available The communication presents the partial results of a research proposing the social contract as a new instrument of analysis for the employment relation in a social context in change, such as the case of Rumania. Until then, the research which aimed at the employment relation which is formed between the employer and the employees widely appealed to the concept of psychological contract (Rousseau, 1989; 1995. The psychological contract, defined as the perception of the mutual obligations assumed by the employee and by the employer, benefited from a fashion effect in the 1990s, when the economic difficulties questioned the model of classic employment relation based on loyalty. However, most of the empirical works on the psychological contract are static studies, for the greater part elaborated by questionnaire, which do not allow to define the impact of the social context change on the evolution of the employment relation. Although certain studies are interested in a context of change (Dick, 2010, most of the past works describe the contents and the evaluation of the psychological contract in an unchanging social environment. Yet, we saw it in the case of the ex-communist countries or those of the Northern Africa, the change in the environment of the employment relation is more present than ever. Our communication proposes a research frame which would be more suited to the understanding of the employment relation in a society in change. To do it, we rely on the social contract in management, which we define as the ensemble of the norms and of the tacit laws existing in a society or a group given with regard to the relation of employment. The approach by the social contract presents the advantage of including multiple elements bound to a societal context, such as the laws, the national culture, the faiths shared by the business environment, etc. (Rousseau, 1995. It offers a new frame of analysis for the employment relation by suggesting that it is

    Adherence to medications prescribed after acute myocardial infarction (AMI) is low. Wireless technology and behavioral economic approaches have shown promise in improving health behaviors. To determine whether a system of medication reminders using financial incentives and social support delays subsequent vascular events in patients following AMI compared with usual care. Two-arm, randomized clinical trial with a 12-month intervention conducted from 2013 through 2016. Investigators were blinded to study group, but participants were not. Design was a health plan-intermediated intervention for members of several health plans. We recruited 1509 participants from 7179 contacted AMI survivors (insured with 5 large US insurers nationally or with Medicare fee-for-service at the University of Pennsylvania Health System). Patients aged 18 to 80 years were eligible if currently prescribed at least 2 of 4 study medications (statin, aspirin, β-blocker, antiplatelet agent), and were hospital inpatients for 1 to 180 days and discharged home with a principal diagnosis of AMI. Patients were randomized 2:1 to an intervention using electronic pill bottles combined with lottery incentives and social support for medication adherence (1003 patients), or to usual care (506 patients). Primary outcome was time to first vascular rehospitalization or death. Secondary outcomes were time to first all-cause rehospitalization, total number of repeated hospitalizations, medication adherence, and total medical costs. A total of 35.5% of participants were female (n = 536); mean (SD) age was 61.0 (10.3) years. There were no statistically significant differences between study arms in time to first rehospitalization for a vascular event or death (hazard ratio, 1.04; 95% CI, 0.71 to 1.52; P = .84), time to first all-cause rehospitalization (hazard ratio, 0.89; 95% CI, 0.73 to 1.09; P = .27), or total number of repeated hospitalizations (hazard ratio, 0.94; 95% CI, 0.60 to 1.48; P

  15. Seismic switch for strong motion measurement

    A seismic switching device is described that has an input signal from an existing microseismic station seismometer and a signal from a strong motion measuring instrument. The seismic switch monitors the signal level of the strong motion instrument and passes the seismometer signal to the station data telemetry and recording systems. When the strong motion instrument signal level exceeds a user set threshold level, the seismometer signal is switched out and the strong motion signal is passed to the telemetry system. The amount of time the strong motion signal is passed before switching back to the seismometer signal is user controlled between 1 and 15 seconds. If the threshold level is exceeded during a switch time period, the length of time is extended from that instant by one user set time period. 11 figs.

    In speciation research, much attention is paid to the evolution of reproductive barriers, preventing diverging groups from hybridizing back into one gene pool. The prevalent view is that reproductive barriers evolve gradually as a by-product of genetic changes accumulated by natural selection and genetic drift in groups that are segregated spatially and/or temporally. Reproductive barriers, however, can also be reinforced by natural selection against maladaptive hybridization. These mutually compatible theories are both empirically supported by studies, analysing relationships between intensity of reproductive isolation and genetic distance in sympatric taxa and allopatric taxa. Here, we present the - to our knowledge - first comparative study in a haplodiploid organism, the social spider mite Stigmaeopsis miscanthi, by measuring premating and post-mating, pre- and post-zygotic components of reproductive isolation, using three recently diverged forms of the mite that partly overlap in home range. We carried out cross-experiments and measured genetic distances (mitochondrial DNA and nuclear DNA) among parapatric and allopatric populations of the three forms. Our results show that the three forms are reproductively isolated, despite the absence of premating barriers, and that the post-mating, prezygotic component contributes most to reproductive isolation. As expected, the strength of post-mating reproductive barriers positively correlated with genetic distance. We did not find a clear pattern of prezygotic barriers evolving faster in parapatry than in allopatry, although one form did show a trend in line with the ecological and behavioural relationships between the forms. Our study advocates the versatility of haplodiploid animals for investigating the evolution of reproductive barriers. © 2018 European Society For Evolutionary Biology.

    Increasing breastfeeding rates in the United States is a national priority. Yet, initiation and duration of breastfeeding remains below national targets. Breastfeeding self-efficacy has been shown to be a strong predictor of both breastfeeding initiation and duration and is therefore an important characteristic to be able to measure. However, there is currently a myriad of instruments for measuring breastfeeding self-efficacy, which makes selection of an appropriate instrument difficult. Thus, our aim was to identify, compare, and critically review available breastfeeding self-efficacy instruments. In a systematic review, 6 breastfeeding self-efficacy instruments were identified. The instruments' purposes, theoretical framework, final scale development, and application in 5 most recent settings were analyzed. The 6 breastfeeding self-efficacy instruments apply a number of theoretical and conceptual frameworks in their development, with Bandura's social cognitive theory being most common. Content, construct, and predictive validity were strong for most scales. Some, but not all, have been successfully adapted to novel settings. In sum, there are several measurements of breastfeeding self-efficacy that can and should be employed to better understand reasons for suboptimal breastfeeding rates and the effects of interventions on breastfeeding self-efficacy. Instrument selection should be based on domains of primary interest, time available, peripartum timing, and assessment of previous adaptations. Failure to apply appropriate measures in research may garner results that are inconclusive, inaccurate, or nonrepresentative of true study effects. © The Author(s) 2015.

    To evaluate whether the effects of providing or receiving social support are more beneficial to reduce mortality risk among the elderly with different educational levels. In this long-term prospective cohort study, data were retrieved from the Taiwan Longitudinal Study on Aging. This study was initiated from 1996 until 2007. The complete data from 1492 males and 1177 females aged ≥67 years were retrieved. Participants received financial, instrumental, and emotional support, and they actively provided instrumental and emotional support to others and involved in social engagement. Education attainment was divided into two levels: high and low. The low education level included illiterate and elementary school. The high education level included junior high school to senior high school and above college. Cox regression analysis was used to examine the association between providing or receiving social support on mortality with different educational levels. The average age of the participants in 1996 was 73.0 (IQR=8.0) years, and the median survival following years (1996-2007) of participants was 10.3 (IQR=6.7) years. Most participants were low educational level including illiterate (39.3%) and elementary school (41.2%). Participants with high educational level tend to be younger and more male significantly. On the contrary, participants with low educational level tend to have significant more poor income, more depression, more cognition impairment, more with IADL and ADL disability than high educational level. Most participants received instrumental support from others (95.5%) and also provided emotional support to others (97.7%). Providing instrumental support can reduce 17% of mortality risk among the elderly with a low level of education after adjusting several covariates [Hazard ratio (HR) = 0.83; 95% confidence interval (CI) = 0.70-0.99; p = 0.036]. Providing instrumental social support to others confer benefits to the giver and prolong life expectancy among the

    Although many studies have suggested social participation (SP) has beneficial effects on elderly people's health, most of them failed to deal with paid work. Additionally, few studies have focused on the age effect between SP and older people's health. To investigate whether the association between SP, including paid work, and instrumental activities of daily living (IADL), exhibits not only in gender, but also in age among community-dwelling older adults. In 2014, we distributed self-administered questionnaires to all community-dwelling elderly aged ≥65 in two medium-sized cities in Nara Prefecture, Japan (n = 32,825). 22,845 residents submitted the questionnaire (response rate, 69.6%). Analyzed subjects were limited to 17,680 persons who had neither dependency in basic ADL nor missing data for required items. SP was assessed based on participation frequency in seven types of social activities: volunteer groups, sports groups, hobby groups, cultural groups, senior citizens' clubs, neighborhood community associations, and paid work. Using Poisson regression models, prevalence ratio for poor IADL was calculated. To examine age and gender differences in the association between SP and IADL, we performed stratified analyses by age and gender group; male young-old (aged 65-74), male old-old (aged ≥75), female young-old, and female old-old. Prevalence of those with poor IADL was 17.1% in males and 4.5% in females, showing a significant gender difference. After adjustment for relevant covariates, volunteer groups were inversely associated with poor IADL only in males and the relationship was stronger in the old-old group than in the young-old group. Conversely, only females had a significant inverse association between paid work and poor IADL, and the association was not reliant on their ages but only those who participated infrequently had a favorable effect. Influence of age in the beneficial association between SP and IADL was generally larger in the old

    Full Text Available The main focus of the investigation from which this article is derived, is to question the recruitment practices as a power device, which means trying to unveiling them as socially accepted instruments of domination that end up in abuses on the participating candidates. These processes, which are part of the human management and administrative duties, are questioned from a hermeneutic perspective, which have its foundations rooted in psychology from where it takes some not contextualized tools. The work is presented synthetically and outlines some final thoughts, not without first addressing some theories from authors that allow in some cases, contextualizing the problem, and in others, sustaining the ethical position which is reflected in this written, establishing intercommunication with some philosophers, being the most important to the analysis: Follett, Weber, Foucault and Deleuze.El objetivo central de la investigación de la cual se deriva el artículo, es interrogar las prácticas de selección de personal en tanto dispositivo de poder, es decir, se pretende develarlas como instrumentos de dominación socialmente aceptados, con los cuales se incurre en abusos sobre los candidatos participantes.

    Increasing breastfeeding rates in the United States is a national priority. Yet, initiation and duration of breastfeeding remains below national targets. Breastfeeding self-efficacy has been shown to be a strong predictor of both breastfeeding initiation and duration and is therefore an important characteristic to be able to measure. However, there is currently a myriad of instruments for measuring breastfeeding self-efficacy, which makes selection of an appropriate instrument difficult. Thus, our aim was to identify, compare, and critically review available breastfeeding self-efficacy instruments. In a systematic review, 6 breastfeeding self-efficacy instruments were identified. The instruments’ purposes, theoretical framework, final scale development, and application in 5 most recent settings were analyzed. The 6 breastfeeding self-efficacy instruments apply a number of theoretical and conceptual frameworks in their development, with Bandura’s social cognitive theory being most common. Content, construct, and predictive validity were strong for most scales. Some, but not all, have been successfully adapted to novel settings. In sum, there are several measurements of breastfeeding self-efficacy that can and should be employed to better understand reasons for suboptimal breastfeeding rates and the effects of interventions on breastfeeding self-efficacy. Instrument selection should be based on domains of primary interest, time available, peripartum timing, and assessment of previous adaptations. Failure to apply appropriate measures in research may garner results that are inconclusive, inaccurate, or nonrepresentative of true study effects. PMID:26319113

  9. Future of radiological instrumentation

    Future trends in the development of radiation protection instrumentation can be expected to be closely related to current trends in political and social activity that drive legislation, rule-making, and standard practice, with assistance provided by trends in material and electronic technology. Wide-range performance will be emphasized to arm the daily worker with instruments that routinely log background rates and, at the same time, are prepared to measure accident rates. Separate and simultaneous accumulation of data from several sensors to ensure complete coverage of the radiation types will be common. Mathematical manipulation of data will provide for summary data logging and, in some cases, solutions to integral equations to provide corrections to experimental data. Instruments will become more reliable by way of self-checking and correction. Miniaturization and large-scale integration of measuring instruments will provide some instrumentation for the people at large. To be effective, the instruments will necessarily cover a wide range and be very reliable. The net result of these several trends will provide for a widespread understanding of radiation protection and an implementation of as low as reasonably achievable among large segments of the population

    At this year's particle physics conference at Brighton, a parallel session was given over to instrumentation and detector development. While this work is vital to the health of research and its continued progress, its share of prime international conference time is limited. Instrumentation can be innovative three times — first when a new idea is outlined, secondly when it is shown to be feasible, and finally when it becomes productive in a real experiment, amassing useful data rather than operational experience. Hyams' examples showed that it can take a long time for a new idea to filter through these successive stages, if it ever makes it at all

    NERSC recently undertook a project to access and analyze Secure Shell (SSH) related data. This includes authentication data such as user names and key fingerprints, interactive session data such as keystrokes and responses, and information about noninteractive sessions such as commands executed and files transferred. Historically, this data has been inaccessible with traditional network monitoring techniques, but with a modification to the SSH daemon, this data can be passed directly to intrusion detection systems for analysis. The instrumented version of SSH is now running on all NERSC production systems. This paper describes the project, details about how SSH was instrumented, and the initial results of putting this in production.

    For better understanding of the specification for seismic instrumentation of a nuclear power plant, the lecture gives some fundamental remarks to the seismic risk in the Federal Republic of Germany and to the data characterizing an earthquake event. Coming from the geophysical properties of an earthquake, the quantities are explained which are used in the design process of nuclear power plants. This process is shortly described in order to find the requirements for the specification of the seismic instrumentation. In addition the demands of licensing authorities are given. As an example the seismic instrumentation of KKP-1, BWR, is shown. The paper deals with kind and number of instruments, their location in the plant and their sensitivity and calibration. Final considerations deal with the evaluation of measured data and with plant operation after an earthquake. Some experience concerning the earthquake behaviour of equipment not designed to withstand earthquake loads is mentioned. This experience has initiated studies directed to quantification of the degree of conservatism of the assumptions in the seismic design of nuclear power plants. A final garget of these studies are more realistic design rules. (RW)

    The Hawking-Penrose theorems tell us that solutions of Einstein's equations are generally singular, in the sense of the incompleteness of causal geodesics (the paths of physical observers). These singularities might be marked by the blowup of curvature and therefore crushing tidal forces, or by the breakdown of physical determinism. Penrose has conjectured (in his `Strong Cosmic Censorship Conjecture`) that it is generically unbounded curvature that causes singularities, rather than causal breakdown. The verification that ``AVTD behavior'' (marked by the domination of time derivatives over space derivatives) is generically present in a family of solutions has proven to be a useful tool for studying model versions of Strong Cosmic Censorship in that family. I discuss some of the history of Strong Cosmic Censorship, and then discuss what is known about AVTD behavior and Strong Cosmic Censorship in families of solutions defined by varying degrees of isometry, and discuss recent results which we believe will extend this knowledge and provide new support for Strong Cosmic Censorship. I also comment on some of the recent work on ``Weak Null Singularities'', and how this relates to Strong Cosmic Censorship.

    In situ thermomechanical experiments are planned as part of the Yucca Mountain Site Characterization Project that require instruments to measure stress and displacement at temperatures that exceed the typical specifications of existing geotechnical instruments. A high degree of instrument reliability will also be required to satisfy the objectives of the experiments, therefore a study was undertaken to identify areas where improvement in instrument performance was required. A preliminary list of instruments required for the experiments was developed, based on existing test planning and analysis. Projected temperature requirements were compared to specifications of existing instruments to identify instrumentation development needs. Different instrument technologies, not currently employed in geotechnical instrumentation, were reviewed to identify potential improvements of existing designs for the high temperature environment. Technologies with strong potentials to improve instrument performance with relatively high reliability include graphite fiber composite materials, fiber optics, and video imagery

  5. Strong Electroweak Symmetry Breaking

    CERN Document Server

    Grinstein, Benjamin

    2011-01-01

    Models of spontaneous breaking of electroweak symmetry by a strong interaction do not have fine tuning/hierarchy problem. They are conceptually elegant and use the only mechanism of spontaneous breaking of a gauge symmetry that is known to occur in nature. The simplest model, minimal technicolor with extended technicolor interactions, is appealing because one can calculate by scaling up from QCD. But it is ruled out on many counts: inappropriately low quark and lepton masses (or excessive FCNC), bad electroweak data fits, light scalar and vector states, etc. However, nature may not choose the minimal model and then we are stuck: except possibly through lattice simulations, we are unable to compute and test the models. In the LHC era it therefore makes sense to abandon specific models (of strong EW breaking) and concentrate on generic features that may indicate discovery. The Technicolor Straw Man is not a model but a parametrized search strategy inspired by a remarkable generic feature of walking technicolor,...

    2011-01-01

    We present a study of the possible plasmon excitations that can occur in systems where strong superconductivity is present. In these systems the plasmon energy is comparable to or smaller than the pairing gap. As a prototype of these systems we consider the proton component of Neutron Star matter just below the crust when electron screening is not taken into account. For the realistic case we consider in detail the different aspects of the elementary excitations when the proton, electron components are considered within the Random-Phase Approximation generalized to the superfluid case, while the influence of the neutron component is considered only at qualitative level. Electron screening plays a major role in modifying the proton spectrum and spectral function. At the same time the electron plasmon is strongly modified and damped by the indirect coupling with the superfluid proton component, even at moderately low values of the gap. The excitation spectrum shows the interplay of the different components and their relevance for each excitation modes. The results are relevant for neutrino physics and thermodynamical processes in neutron stars. If electron screening is neglected, the spectral properties of the proton component show some resemblance with the physical situation in high-T c superconductors, and we briefly discuss similarities and differences in this connection. In a general prospect, the results of the study emphasize the role of Coulomb interaction in strong superconductors.

    RFS or Regles Fondamentales de Surete (Basic Safety Rules) applicable to certain types of nuclear facilities lay down requirements with which compliance, for the type of facilities and within the scope of application covered by the RFS, is considered to be equivalent to compliance with technical French regulatory practice. The object of the RFS is to take advantage of standardization in the field of safety, while allowing for technical progress in that field. They are designed to enable the operating utility and contractors to know the rules pertaining to various subjects which are considered to be acceptable by the Service Central de Surete des Installations Nucleaires, or the SCSIN (Central Department for the Safety of Nuclear Facilities). These RFS should make safety analysis easier and lead to better understanding between experts and individuals concerned with the problems of nuclear safety. The SCSIN reserves the right to modify, when considered necessary, any RFS and specify, if need be, the terms under which a modification is deemed retroactive. The aim of this RFS is to define the type, location and operating conditions for seismic instrumentation needed to determine promptly the seismic response of nuclear power plants features important to safety to permit comparison of such response with that used as the design basis

    Standard path-integral techniques such as instanton calculations give good answers for weak-coupling problems, but become unreliable for strong-coupling. Here we consider a method of replacing the original potential by a suitably chosen harmonic oscillator potential. Physically this is motivated by the fact that potential barriers below the level of the ground-state energy of a quantum-mechanical system have little effect. Numerically, results are good, both for quantum-mechanical problems and for massive phi 4 field theory in 1 + 1 dimensions. 9 references, 6 figures

    With an assumed weak multiplet structure for bosonic hadrons, which is consistent with the ΔI = 1/2 rule, it is shown that the strong interaction effective hamiltonian is compatible with the weak SU(2) x U(1) gauge transformation. Especially the rho-meson transforms as a triplet under SU(2)sub(w), and this is the origin of the rho-photon analogy. It is also shown that the existence of the non-vanishing Cabibbo angle is a necessary condition for the absence of the exotic hadrons. (orig.)

    We show that whenever a 4-dimensional theory with N particle species emerges as a consistent low energy description of a 3-brane embedded in an asymptotically-flat (4+d)-dimensional space, the holographic scale of high-dimensional gravity sets the strong coupling scale of the 4D theory. This connection persists in the limit in which gravity can be consistently decoupled. We demonstrate this effect for orbifold planes, as well as for the solitonic branes and string theoretic D-branes. In all cases the emergence of a 4D strong coupling scale from bulk holography is a persistent phenomenon. The effect turns out to be insensitive even to such extreme deformations of the brane action that seemingly shield 4D theory from the bulk gravity effects. A well understood example of such deformation is given by large 4D Einstein term in the 3-brane action, which is known to suppress the strength of 5D gravity at short distances and change the 5D Newton's law into the four-dimensional one. Nevertheless, we observe that the ...

    At the McGee Creek, California, site, 3-component strong-motion accelerometers are located at depths of 166 m, 35 m and 0 m. The surface material is glacial moraine, to a depth of 30.5 m, overlying homfels. Accelerations were recorded from two California earthquakes: Round Valley, M L 5.8, November 23, 1984, 18:08 UTC and Chalfant Valley, M L 6.4, July 21, 1986, 14:42 UTC. By separating out the SH components of acceleration, we were able to determine the orientations of the downhole instruments. By separating out the SV component of acceleration, we were able to determine the approximate angle of incidence of the signal at 166 m. A constant phase velocity Haskell-Thomson model was applied to generate synthetic SH seismograms at the surface using the accelerations recorded at 166 m. In the frequency band 0.0 - 10.0 Hz, we compared the filtered synthetic records to the filtered surface data. The onset of the SH pulse is clearly seen, as are the reflections from the interface at 30.5 m. The synthetic record closely matches the data in amplitude and phase. The fit between the synthetic accelerogram and the data shows that the seismic amplification at the surface is a result of the contrast of the impedances (shear stiffnesses) of the near surface materials

    Our friend and colleague John Strong was cruelly taken from us by a brain tumour on Monday 31st July, a few days before his 65th birthday John started his career working with a group from Westfield College, under the leadership of Ted Bellamy. He obtained his PhD and spent the early part of his career on experiments at Rutherford Appleton Laboratory (RAL), but after the early 1970s his research was focussed on experiments in CERN. Over the years he made a number of notable contributions to experiments in CERN: The Omega spectrometer adopted a system John had originally developed for experiments at RAL using vidicon cameras to record the sparks in the spark chambers; He contributed to the success of NA1 and NA7, where he became heavily involved in the electronic trigger systems; He was responsible for the second level trigger system for the ALEPH detector and spent five years leading a team that designed and built the system, which ran for twelve years with only minor interventions. Following ALEPH he tur...

  20. Stirring Strongly Coupled Plasma

    Fadafan, Kazem Bitaghsir; Rajagopal, Krishna; Wiedemann, Urs Achim

    2009-01-01

    We determine the energy it takes to move a test quark along a circle of radius L with angular frequency w through the strongly coupled plasma of N=4 supersymmetric Yang-Mills (SYM) theory. We find that for most values of L and w the energy deposited by stirring the plasma in this way is governed either by the drag force acting on a test quark moving through the plasma in a straight line with speed v=Lw or by the energy radiated by a quark in circular motion in the absence of any plasma, whichever is larger. There is a continuous crossover from the drag-dominated regime to the radiation-dominated regime. In the crossover regime we find evidence for significant destructive interference between energy loss due to drag and that due to radiation as if in vacuum. The rotating quark thus serves as a model system in which the relative strength of, and interplay between, two different mechanisms of parton energy loss is accessible via a controlled classical gravity calculation. We close by speculating on the implicati...

  1. Strong-interaction nonuniversality

    International Nuclear Information System (INIS)

    Volkas, R.R.; Foot, R.; He, X.; Joshi, G.C.

    1989-01-01

    The universal QCD color theory is extended to an SU(3) 1 direct product SU(3) 2 direct product SU(3) 3 gauge theory, where quarks of the ith generation transform as triplets under SU(3)/sub i/ and singlets under the other two factors. The usual color group is then identified with the diagonal subgroup, which remains exact after symmetry breaking. The gauge bosons associated with the 16 broken generators then form two massive octets under ordinary color. The interactions between quarks and these heavy gluonlike particles are explicitly nonuniversal and thus an exploration of their physical implications allows us to shed light on the fundamental issue of strong-interaction universality. Nonuniversality and weak flavor mixing are shown to generate heavy-gluon-induced flavor-changing neutral currents. The phenomenology of these processes is studied, as they provide the major experimental constraint on the extended theory. Three symmetry-breaking scenarios are presented. The first has color breaking occurring at the weak scale, while the second and third divorce the two scales. The third model has the interesting feature of radiatively induced off-diagonal Kobayashi-Maskawa matrix elements

Recentemente, as dimensões cognitivas têm sido incorporadas aos projetos de produto. O propósito deste artigo é discutir e demonstrar a importância das interações sociocognitivas no projeto de instrumentos de trabalho no nível de relações físicas, sempre tratados segundo modelos biomecânicos e variáveis fisiológicas. Tomando como exemplo o projeto de bancada de inspeção de produtos farmacêuticos, mostramos como esse projeto, para se ajustar aos modos operatórios, teve que atender os condicionantes intersubjetivos do contexto social no qual se insere a atividade.The social nature of objects is recognized in their formal or aesthetic aspects, but this does not always generate guidelines for design in the functional aspect. Recently, cognitive dimensions have been incorporated into product design. Our intention in this article is to argue and demonstrate the importance of socio-cognitive interactions in the design of work instruments at the level of physical relations, always treated in accordance with biomechanical models. Taking as example the design of a work station for pharmaceutical products inspection, we show how the design had also to take into account the subjective conditioners derived from the social context in which the activity occurs.

    Full Text Available Neste artigo demonstramos, a partir de uma replicação qualitativa de um estudo quantitativo, que os sistemas fechados de interação - aqui denominados capital social - e os abertos - laços fracos - são fenômenos de natureza distinta e, consequentemente, desempenham funções distintas na determinação da capacidade de articulação coletiva de indivíduos e no grau de eficácia de ações coletivas. A hipótese principal do artigo é que, enquanto capital social tem a ver com maior capacidade dos membros da comunidade para articular mobilização social, os laços fracos dizem respeito à capacidade de a comunidade conseguir benefícios, como saneamento básico, segurança pública, transporte coletivo, saúde e lazer - aqui denominada eficácia coletiva. A metodologia adotada baseia-se na replicação qualitativa de um survey, com três estudos de caso em comunidades periféricas da Região Metropolitana de Belo Horizonte, sobre a importância dos laços fracos para a ação eficaz da comunidade diante do poder público.This article demonstrates, through a qualitative replication of a quantitative research - a survey - that the concepts of closed interaction systems - social capital - and open ones - weak ties - refer to different kinds of social phenomena and, therefore, have independent roles in determining the individuals' capability of collective articulation as well as the effectiveness of the collective actions. The main hypothesis is that while social capital has to do with the people's ability to articulate social mobilization, weak ties have to do with the community's capability to obtain services such as sanitation, public safety, transportation, health care and leisure facilities - here called collective effectiveness. The study comprised a qualitative replication of a survey, with three case studies of low-income communities in the Belo Horizonte metropolitan area.

  9. EDITORIAL: Strongly correlated electron systems Strongly correlated electron systems

    Ronning, Filip; Batista, Cristian

    2011-03-01

    Strongly correlated electrons is an exciting and diverse field in condensed matter physics. This special issue aims to capture some of that excitement and recent developments in the field. Given that this issue was inspired by the 2010 International Conference on Strongly Correlated Electron Systems (SCES 2010), we briefly give some history in order to place this issue in context. The 2010 International Conference on Strongly Correlated Electron Systems was held in Santa Fe, New Mexico, a reunion of sorts from the 1989 International Conference on the Physics of Highly Correlated Electron Systems that also convened in Santa Fe. SCES 2010—co-chaired by John Sarrao and Joe Thompson—followed the tradition of earlier conferences, in this century, hosted by Buzios (2008), Houston (2007), Vienna (2005), Karlsruhe (2004), Krakow (2002) and Ann Arbor (2001). Every three years since 1997, SCES has joined the International Conference on Magnetism (ICM), held in Recife (2000), Rome (2003), Kyoto (2006) and Karlsruhe (2009). Like its predecessors, SCES 2010 topics included strongly correlated f- and d-electron systems, heavy-fermion behaviors, quantum-phase transitions, non-Fermi liquid phenomena, unconventional superconductivity, and emergent states that arise from electronic correlations. Recent developments from studies of quantum magnetism and cold atoms complemented the traditional subjects and were included in SCES 2010. 2010 celebrated the 400th anniversary of Santa Fe as well as the birth of astronomy. So what's the connection to SCES? The Dutch invention of the first practical telescope and its use by Galileo in 1610 and subsequent years overturned dogma that the sun revolved about the earth. This revolutionary, and at the time heretical, conclusion required innovative combinations of new instrumentation, observation and mathematics. These same combinations are just as important 400 years later and are the foundation of scientific discoveries that were discussed

    The earliest astronomical instruments used in India were the gnomon and the water clock. In the early seventh century, Brahmagupta described ten types of instruments, which were adopted by all subsequent writers with minor modifications. Contact with Islamic astronomy in the second millennium AD led to a radical change. Sanskrit texts began to lay emphasis on the importance of observational instruments. Exclusive texts on instruments were composed. Islamic instruments like the astrolabe were adopted and some new types of instruments were developed. Production and use of these traditional instruments continued, along with the cultivation of traditional astronomy, up to the end of the nineteenth century.

    The network intended to record strong ground motion in continental France is composed for the most part of instrument packages incorporated into nuclear installations, which are supplemented by a certain number of accelerometers placed in the most highly seismic areas. In a country where the level of seismicity is relatively modest, such a network is not conductive to the acquisition of new data, which, instead, is obtained through spot studies of limited duration using more sensitive instruments or through the recording of strong ground motion in neighbouring countries [fr

    During the 1970s and 1980s, before synthesizers based on direct sampling of musical sounds became popular, replicating musical instruments using frequency modulation (FM) or wavetable synthesis was one of the “holy grails” of music synthesis. Synthesizers such as the Yamaha DX7 allowed users great flexibility in mixing and matching sounds, but were notoriously difficult to coerce into producing sounds like those of a given instrument. Instrument design wizards practiced the mysteries of FM instrument design.

The safety latch will be welded to the strong-back and will latch to a 1.5-in. dia cantilever rod welded to the pump baseplate. The static and dynamic analysis shows that the safety latch will hold the strong-back to the pump if the friction clamps fail and the pump become free from the strong-back. Thus, the safety latch will meet the requirements of the Lifting and Rigging Manual for under the hook lifting for static loading; it can withstand shock loads from the strong-back falling 0.25 inch

    Titanium (Ti) is a strong silver-gray metal that is highly resistant to corrosion and is chemically inert. It is as strong as steel but 45 percent lighter, and it is twice as strong as aluminum but only 60 percent heavier. Titanium dioxide (TiO2) has a very high refractive index, which means that it has high light-scattering ability. As a result, TiO2 imparts whiteness, opacity, and brightness to many products. ...Because of the unique physical properties of titanium metal and the whiteness provided by TiO2, titanium is now used widely in modern industrial societies.

    The requirements and characteristics of radiation measurement instruments vary according to the circumstances under which they are used (field, area, laboratory conditions) and according to their purpose (radiation survey, personal monitoring, use in emergencies, or alpha, beta or gamma counting). In fact, radiation measurement instruments are so varied that only an overview has been presented here. Groups of instruments for these and other conditions or uses are presented in tabular form together with their operational characteristics and requirements. While examples of calibrations, efficiencies and variability of all the listed instruments are not given in this chapter, these parameters are illustrated for the most important types of gamma and beta survey instruments, in some cases with a specific instrument used as an example. Some of the important parameters that need to be considered for laboratory counting of alpha and beta particles are presented. Charts for determination of optimum sample and background counting times, errors and statistics are given

    Westinghouse Hanford Company Project W-211 is responsible for providing the system capabilities to remove radioactive waste from ten double-shell tanks used to store radioactive wastes on the Hanford Site in Richland, Washington. The project is also responsible for measuring tank waste slurry properties prior to injection into pipeline systems, including the Replacement of Cross-Site Transfer System. This report summarizes studies of the appropriateness of the instrumentation specified for use in Project W-211. The instruments were evaluated in a test loop with simulated slurries that covered the range of properties specified in the functional design criteria. The results of the study indicate that the compact nature of the baseline Project W-211 loop does not result in reduced instrumental accuracy resulting from poor flow profile development. Of the baseline instrumentation, the Micromotion densimeter, the Moore Industries thermocouple, the Fischer and Porter magnetic flow meter, and the Red Valve Pressure transducer meet the desired instrumental accuracy. An alternate magnetic flow meter (Yokagawa) gave nearly identical results as the baseline fischer and Porter. The Micromotion flow meter did not meet the desired instrument accuracy but could potentially be calibrated so that it would meet the criteria. The Nametre on-line viscometer did not meet the desired instrumental accuracy and is not recommended as a quantitative instrument although it does provide qualitative information. The recommended minimum set of instrumentation necessary to ensure the slurry meets the Project W-058 acceptance criteria is the Micromotion mass flow meter and delta pressure cells

    Energy Technology Data Exchange (ETDEWEB)

    1993-03-01

    Deficiencies exist in both the performance and the quality of health physics instruments. Recognizing the implications of such deficiencies for the protection of workers and the public, in the early 1980s the DOE and the NRC encouraged the development of a performance standard and established a program to test a series of instruments against criteria in the standard. The purpose of the testing was to establish the practicality of the criteria in the standard, to determine the performance of a cross section of available instruments, and to establish a testing capability. Over 100 instruments were tested, resulting in a practical standard and an understanding of the deficiencies in available instruments. In parallel with the instrument testing, a value-impact study clearly established the benefits of implementing a formal testing program. An ad hoc committee also met several times to establish recommendations for the voluntary implementation of a testing program based on the studies and the performance standard. For several reasons, a formal program did not materialize. Ongoing tests and studies have supported the development of specific instruments and have helped specific clients understand the performance of their instruments. The purpose of this presentation is to trace the history of instrument testing to date and suggest the benefits of a centralized formal program.

  19. The SNAP Strong Lens Survey

    Energy Technology Data Exchange (ETDEWEB)

    Marshall, P.

    2005-01-03

    Basic considerations of lens detection and identification indicate that a wide field survey of the types planned for weak lensing and Type Ia SNe with SNAP are close to optimal for the optical detection of strong lenses. Such a ''piggy-back'' survey might be expected even pessimistically to provide a catalogue of a few thousand new strong lenses, with the numbers dominated by systems of faint blue galaxies lensed by foreground ellipticals. After sketching out our strategy for detecting and measuring these galaxy lenses using the SNAP images, we discuss some of the scientific applications of such a large sample of gravitational lenses: in particular we comment on the partition of information between lens structure, the source population properties and cosmology. Understanding this partitioning is key to assessing strong lens cosmography's value as a cosmological probe.

  20. Strong coupling phase in QED

    International Nuclear Information System (INIS)

    Aoki, Ken-ichi

    1988-01-01

    Existence of a strong coupling phase in QED has been suggested in solutions of the Schwinger-Dyson equation and in Monte Carlo simulation of lattice QED. In this article we recapitulate the previous arguments, and formulate the problem in the modern framework of the renormalization theory, Wilsonian renormalization. This scheme of renormalization gives the best understanding of the basic structure of a field theory especially when it has a multi-phase structure. We resolve some misleading arguments in the previous literature. Then we set up a strategy to attack the strong phase, if any. We describe a trial; a coupled Schwinger-Dyson equation. Possible picture of the strong coupling phase QED is presented. (author)

    Full Text Available The subject of this paper is focused on the instruments for the measurement of corporate reputation. Recent research of the elements which influence the success of a company shows a growing interest in intangible values. Corporate reputation itself has been identified as one of the key intangible assets which create the company’s added value. Understanding of the importance of corporate reputation has been determined as a significant component of the company’s competitiveness, that is, of its competitive edge. Reputation is a normal part of our life and an integral part of our society. Our interest in the honesty and integrity of others is firmly established in all cultures and nowadays the focus of this interest is switching increasingly on companies. Corporate reputation can be acquired by means of strong, well-developed strategies, which are crucial for the opinion of stakeholders regarding future stability and competitive sustainability of the company. On the other hand, it should be emphasized that in order to manage it, corporate reputation has to be measured first. However, although the concept of corporate reputation is universally accepted and its significance has been recognized especially in the last two decades, the process of its measurement is still at an early stage and there is no universally accepted instrument for its measurement. Therefore, the author of this paper gives an overview of the instruments used for the measurement of corporate reputation which have gained a foothold through former practical usage.

    The beam-beam interaction puts a strong limit on the luminosity of the high energy storage ring colliders. At the interaction points, the electromagnetic fields generated by one beam focus or defocus the opposite beam. This can cause beam blowup and a reduction of luminosity. An accurate simulation of the beam-beam interaction is needed to help optimize the luminosity in high energy colliders.

    2015-01-01

    Neutron scattering instruments in HANARO research reactor have been contributed to various fields of basic science and material engineering. These instruments are open to publics and researchers can apply beam-time and do experiments with instrument scientists. In most cases, these instruments run for several weeks without stopping, and therefore instrument scientist wants to see the instrument status and receive information if the instruments have some problem. This is important for the safety. However, it is very hard to get instrument information outside of instruments. Access from external site is strongly forbidden in the institute due to the network safety, I developed another way to send instrument status information using commercial short messaging service(SMS). In this presentation, detailed features of this system will be shown. As a prototype, this system is being developed for the single instrument: Disk-chopper time-of-flight instruments (DC-TOF). I have successfully developed instruments and operate for several years. This information messaging system can be used for other neutron scattering instruments

  13. PREFACE: Strongly correlated electron systems Strongly correlated electron systems

    Science.gov (United States)

    Saxena, Siddharth S.; Littlewood, P. B.

    2012-07-01

    This special section is dedicated to the Strongly Correlated Electron Systems Conference (SCES) 2011, which was held from 29 August-3 September 2011, in Cambridge, UK. SCES'2011 is dedicated to 100 years of superconductivity and covers a range of topics in the area of strongly correlated systems. The correlated electronic and magnetic materials featured include f-electron based heavy fermion intermetallics and d-electron based transition metal compounds. The selected papers derived from invited presentations seek to deepen our understanding of the rich physical phenomena that arise from correlation effects. The focus is on quantum phase transitions, non-Fermi liquid phenomena, quantum magnetism, unconventional superconductivity and metal-insulator transitions. Both experimental and theoretical work is presented. Based on fundamental advances in the understanding of electronic materials, much of 20th century materials physics was driven by miniaturisation and integration in the electronics industry to the current generation of nanometre scale devices. The achievements of this industry have brought unprecedented advances to society and well-being, and no doubt there is much further to go—note that this progress is founded on investments and studies in the fundamentals of condensed matter physics from more than 50 years ago. Nevertheless, the defining challenges for the 21st century will lie in the discovery in science, and deployment through engineering, of technologies that can deliver the scale needed to have an impact on the sustainability agenda. Thus the big developments in nanotechnology may lie not in the pursuit of yet smaller transistors, but in the design of new structures that can revolutionise the performance of solar cells, batteries, fuel cells, light-weight structural materials, refrigeration, water purification, etc. The science presented in the papers of this special section also highlights the underlying interest in energy-dense materials, which

  14. Are Facebook "Friends" Helpful? Development of a Facebook-Based Measure of Social Support and Examination of Relationships Among Depression, Quality of Life, and Social Support.

    Greater social support is predictive of lower depression and higher quality of life (QOL). However, the way in which social support is provided has changed greatly with the expanding role of social networking sites (e.g., Facebook). While there are numerous anecdotal accounts of the benefits of Facebook-based social support, little empirical evidence exists to support these assertions, and there are no empirically validated measures designed to assess social support provided via this unique social networking medium. This study sought to develop an empirically sound measure of Facebook-based social support (Facebook Measure of Social Support [FMSS]) and to assess how this new measure relates to previously established measures of support and two outcome variables: depression and QOL. Following exploratory factor analysis, the FMSS was determined to assess four factors of social support on Facebook (Perceived, Emotional, Negative, Received/Instrumental). The Negative Support factor on the FMSS was most strongly related to both depression and QOL with magnitudes (and direction of relationships) comparable to a traditional measure of perceived social support. However, two FMSS factors (Received/Instrumental and Perceived) were unrelated to both mental health outcomes. Contrary to expectations, elevations in one FMSS factor (Emotional) was associated with worse symptoms of depression and poorer psychological QOL. When taken together, only the absence of negative social support on Facebook is significantly predictive of mental health functioning. Consequently, those hoping to use Facebook as a medium for reducing depression or improving QOL are unlikely to realize significant therapeutic benefits.

    Full Text Available The World Health Organization (WHO Framework Convention on Tobacco Control (FCTC is a unique global health instrument, since it is in the health field the only instrument that is international law. After the 10 years of its existence an Independent Expert Group assessed the impact of the FCTC using all available data and visiting a number of countries interviewing different stakeholders. It is quite clear that the Treaty has acted as a strong catalyst and framework for national actions and that remarkable progress in global tobacco control can be seen. At the same time FCTC has moved tobacco control in countries from a pure health issue to a legal responsibility of the whole government, and on the international level created stronger interagency collaboration. The assessment also showed the many challenges. The spread of tobacco use, as well as of other risk lifestyles, is related to globalization. FCTC is a pioneering example of global action to counteract the negative social consequences of globalization. A convention is not an easy instrument, but the FCTC has undoubtedly sparked thinking and development of other stronger public health instruments and of needed governance structures.

    2015-01-01

    The continuous evolution and development of experimental techniques is at the basis of any fundamental achievement in modern physics. Strongly correlated systems (SCS), more than any other, need to be investigated through the greatest variety of experimental techniques in order to unveil and crosscheck the numerous and puzzling anomalous behaviors characterizing them. The study of SCS fostered the improvement of many old experimental techniques, but also the advent of many new ones just invented in order to analyze the complex behaviors of these systems. Many novel materials, with functional properties emerging from macroscopic quantum behaviors at the frontier of modern research in physics, chemistry and materials science, belong to this class of systems. The volume presents a representative collection of the modern experimental techniques specifically tailored for the analysis of strongly correlated systems. Any technique is presented in great detail by its own inventor or by one of the world-wide recognize...

    Cveticanin, Livija

    2014-01-01

    This book provides the presentation of the motion of pure nonlinear oscillatory systems and various solution procedures which give the approximate solutions of the strong nonlinear oscillator equations. The book presents the original author’s method for the analytical solution procedure of the pure nonlinear oscillator system. After an introduction, the physical explanation of the pure nonlinearity and of the pure nonlinear oscillator is given. The analytical solution for free and forced vibrations of the one-degree-of-freedom strong nonlinear system with constant and time variable parameter is considered. Special attention is given to the one and two mass oscillatory systems with two-degrees-of-freedom. The criteria for the deterministic chaos in ideal and non-ideal pure nonlinear oscillators are derived analytically. The method for suppressing chaos is developed. Important problems are discussed in didactic exercises. The book is self-consistent and suitable as a textbook for students and also for profess...

    1998-01-01

    We show that the fermion mass spectrum may naturally be understood in terms of flavour democratic fixed points in supersymmetric theories which have a large domain of attraction in the presence of "strong unification". Our approach provides an alternative to the approximate Yukawa texture zeroes of the Froggatt-Nielsen mechanism. We discuss a particular model based on a broken gauged $SU(3)_L\\times SU(3)_R$ family symmetry which illustrates our approach.

    1996-07-01

    In the past decade, great technological progress has been made in telemaintenance of mainframe and mini computers. As hardware technology is now available at an acceptable cost, computer aided trouble-shooting can be adapted to laboratory instrumentation in order to significantly improve repair time, avoid instrument downtime by taking advantage of predictive methods, and provide general diagnostic assistance. Depending on the size of the instrument, the telemaintenance facility can be dedicated to a single instrument or alternatively a telemaintenance server can manage multiple distributed small instruments through a Local Area Network. As complex failures can occur, the local diagnosis capabilities may be exceeded and automatic dialing for connection to computerized Remote Maintenance Centers is needed. The main advantages of such a centre, as compared to local diagnosis systems, are the increased access to more information and experience of failures from instrument installations, and consequently the provision of training data updates for Artificial Neural Networks and Knowledge Based Systems in general. When an abnormal situation is detected or anticipated by a diagnosis module, an automatic alert is given to the user, local diagnosis is activated, and for simple solutions, instructions are given to the operator. In the last resort, a human expert can be alerted who, with remote control tools, can attend to the failures. For both local and remote trouble-shooting, the data provided by the instrument and connected workstation is of paramount importance for the efficiency and accuracy of the diagnosis. Equally, the importance of standardization of telemaintenance communication protocols is addressed.

  15. Nuclear instrument technician training

    International Nuclear Information System (INIS)

    Wollesen, E.S.

    1991-01-01

    This paper reports on Nuclear Instrument Technician (NIT) training that has developed at an accelerated rate over the past three decades. During the 1960's commercial nuclear power plants were in their infancy. For that reason, there is little wonder that NIT training had little structure and little creditability. NIT training, in many early plants, was little more than On-The Job Training (OJT). The seventies brought changes in Instrumentation and Controls as well as emphasis on the requirements for more in depth training and documentation. As in the seventies, the eighties saw not only changes in technologies but tighter requirements, standardized training and the development of accredited Nuclear Instrument Training; thus the conclusion: Nuclear Instrument Training Isn't What It Used To Be

  16. Atoms in strong laser fields

    International Nuclear Information System (INIS)

    L'Huillier, A.

    2002-01-01

    When a high-power laser focuses into a gas of atoms, the electromagnetic field becomes of the same magnitude as the Coulomb field which binds a 1s electron in a hydrogen atom. 3 highly non-linear phenomena can happen: 1) ATI (above threshold ionization): electrons initially in the ground state absorb a large number of photons, many more than the minimum number required for ionization; 2) multiple ionization: many electrons can be emitted one at a time, in a sequential process, or simultaneously in a mechanism called direct or non-sequential; and 3) high order harmonic generation (HHG): efficient photon emission in the extreme ultraviolet range, in the form of high-order harmonics of the fundamental laser field can occur. The theoretical problem consists in solving the time dependent Schroedinger equation (TDSE) that describes the interaction of a many-electron atom with a laser field. A number of methods have been proposed to solve this problem in the case of a hydrogen atom or a single-active electron atom in a strong laser field. A large effort is presently being devoted to go beyond the single-active approximation. The understanding of the physics of the interaction between atoms and strong laser fields has been provided by a very simple model called ''simple man's theory''. A unified view of HHG, ATI, and non-sequential ionization, originating from the simple man's model and the strong field approximation, expressed in terms of electrons trajectories or quantum paths is slowly emerging.

    Full Text Available In the presence of approximate global symmetries that forbid relevant interactions, strongly coupled light Dark Matter (DM can appear weakly coupled at small energy and generate a sizable relic abundance. Fundamental principles like unitarity restrict these symmetries to a small class, where the leading interactions are captured by effective operators up to dimension-8. Chiral symmetry, spontaneously broken global symmetries and non-linearly realized supersymmetry are examples of this. Their DM candidates (composite fermions, pseudo Nambu-Goldstone Bosons and Goldstini are interesting targets for LHC missing-energy searches.

    2015-01-01

    The scalar strong interaction hadron theory, SSI, is a first principles' and nonlocal theory at quantum mechanical level that provides an alternative to low energy QCD and Higgs related part of the standard model. The quark-quark interaction is scalar rather than color-vectorial. A set of equations of motion for mesons and another set for baryons have been constructed. This book provides an account of the present state of a theory supposedly still at its early stage of development. This work will facilitate researchers interested in entering into this field and serve as a basis for possible future development of this theory.

  1. Strong Plate, Weak Slab Dichotomy

    2015-12-01

    Models of mantle convection on Earth produce styles of convection that are not observed on Earth.Moreover non-Earth-like modes, such as two-sided downwellings, are the de facto mode of convection in such models.To recreate Earth style subduction, i.e. one-sided asymmetric recycling of the lithosphere, proper treatment of the plates and plate interface are required. Previous work has identified several model features that promote subduction. A free surface or pseudo-free surface and a layer of material with a relatively low strength material (weak crust) allow downgoing plates to bend and slide past overriding without creating undue stress at the plate interface. (Crameri, et al. 2012, GRL)A low viscosity mantle wedge, possibly a result of slab dehydration, decouples the plates in the system. (Gerya et al. 2007, Geo)Plates must be composed of material which, in the case of the overriding plate, are is strong enough to resist bending stresses imposed by the subducting plate and yet, as in the case of the subducting plate, be weak enough to bend and subduct when pulled by the already subducted slab. (Petersen et al. 2015, PEPI) Though strong surface plates are required for subduction such plates may present a problem when they encounter the lower mantle.As the subducting slab approaches the higher viscosity, lower mantle stresses are imposed on the tip.Strong slabs transmit this stress to the surface.There the stress field at the plate interface is modified and potentially modifies the style of convection. In addition to modifying the stress at the plate interface, the strength of the slab affects the morphology of the slab at the base of the upper mantle. (Stegman, et al 2010, Tectonophysics)Slabs that maintain a sufficient portion of their strength after being bent require high stresses to unbend or otherwise change their shape.On the other hand slabs that are weakened though the bending process are more amenable to changes in morphology. We present the results of

    Hamaguchi, Shinsuke

    2014-07-01

    Thermography is an imaging method using the instrument to detect infrared rays emitted from the body surface, and to plot them as a distribution diagram of the temperature information. Therefore, a thermographic instrument can be assumed to measure the skin temperature of the diseased region. Such an instrument is a useful device for noninvasive and objective assessment of various diseases. Examination using a thermographic instrument can assess the autonomic dysfunction by measuring the skin blood flow involved with the sympathetic innervation. Thermography is useful in assisting the determination of the therapeutic effect. However, autonomic dysfunction should be confirmed correctly with the assessment of thermatome that shows abnormal thermal distribution in the region of the disease. Thermography should make noticeable the difference between the body temperature of abnormal and normal sites, and show the alteration of temperature. Monitoring using thermography is useful to determine the effect of sympathetic nerve block. If a thermographic instrument is used, it is important that examiners should understand the function of the instrument, as well as its advantages and disadvantages.

  6. Problems with radiological surveillance instrumentation

    1984-09-01

    Many radiological surveillance instruments are in use at DOE facilities throughout the country. These instruments are an essential part of all health physics programs, and poor instrument performance can increase program costs or compromise program effectiveness. Generic data from simple tests on newly purchased instruments shows that many instruments will not meet requirements due to manufacturing defects. In other cases, lack of consideration of instrument use has resulted in poor acceptance of instruments and poor reliability. The performance of instruments is highly variable for electronic and mechanical performance, radiation response, susceptibility to interferences and response to environmental factors. Poor instrument performance in these areas can lead to errors or poor accuracy in measurements

    2017-11-03

    Stigmatization is the assignment of negative perceptions to an individual because of a perceived difference from the population at large. Skin conditions are frequently the reason of social rejection with a consequent negative influence on the personal and social life of patients. The aim of the current study was to review the available instruments that can be successfully utilized to measure the stigmatization level among dermatological patients. We performed our search on PubMed up to November 2016 and utilized combinations of key phrases containing such words as stigmatization, skin, dermatology, names of various skin conditions (psoriasis, vitiligo, acne, etc.), measurement. The search found a considerable number of articles - 548. After filtering them through a precise selection process, 58 articles remained. We concentrated only on the methodological aspects to assess stigmatization in various dermatoses. The review ascertained that there exist numerous instruments in the form of questionnaires. They were utilized in various researches in order to assess the stigmatization level in patients with skin problems. We divided them into two main groups: dermatology specific instruments (6 questionnaires) and dermatosis/disease specific ones (8 questionnaires). It is recommended to use dermatology-specific instruments to compare the stigmatization level in various skin conditions. They can be utilized as well as a first line tools to study the feeling of stigmatization in specific skin diseases; however, where it is possible, they should be supplemented with the disease-specific instrument for deeper analysis of both qualities of life and stigmatization.

    The Gulf of Gökova is located in southwestern Turkey near the Aegean Sea and surrounded by Datça Peninsula to the south, the island of Kos to the west and Bodrum Peninsula to the north. The Bodrum peninsula with a population of one million in summer season is one of the most populated touristic centers of Turkey. This region is also surrounded by numerous active seismic entities such as Ula-Ören Fault Zone, Gökova Graben etc.. and demonstrates high seismic hazard. In the past, many destructive earthquakes have occurred in southwestern Turkey. One of the destructive historical earthquakes is 1493 Kos event (Mw=6.9) caused heavy damage in Bodrum. In the instrumental period seismic activity in the Gökova region includes the Ms>6.0 earthquakes of 23 April 1933 (Ms=6.4), 23 May 1941 (Ms=6.0), 13 December 1941 (Ms=6.5) events. Intense earthquake activity (Mw5+) occurred in Gulf of Gökova in August 2004 and January 2005. Considering the high seismicity and population of this region, a strong ground motion monitoring system stationed in dense settlements in the Bodrum Peninsula: Bodrum, Turgutreis, Yalıkavak, Çiftlik and Ortakent was deployed on June 2015. The network consists of 5 strong motion recorders, has been set up with the aim of monitoring of regional earthquakes, collecting accurate and reliable data for engineering and scientific research purposes, in particular to provide input for future earthquake rapid reporting and early warning implementation projects on urban environments in the Bodrum peninsula and the surrounding areas. In this poster presentation, we briefly introduce the Bodrum Network and discuss our future plans for further developments.

    Conceived in the 1960s, the Landsat program has experienced six successful missions that have contributed to an unprecedented 39-year record of Earth Observations that capture global land conditions and dynamics. Incremental improvements in imaging capabilities continue to improve the quality of Landsat science data, while ensuring continuity over the full instrument record. Landsats 5 and 7 are still collecting imagery. The planned launch of the Landsat Data Continuity Mission in December 2012 potentially extends the Landsat record to nearly 50 years. The U.S. Geological Survey (USGS) Landsat archive contains nearly three million Landsat images. All USGS Landsat data are available at no cost via the Internet. The USGS is committed to improving the content of the historical Landsat archive though the consolidation of Landsat data held in international archives. In addition, the USGS is working on a strategy to develop higher-level Landsat geo- and biophysical datasets. Finally, Federal efforts are underway to transition Landsat into a sustained operational program within the Department of the Interior and to authorize the development of the next two satellites — Landsats 9 and 10.

  10. Regional cooperation on nuclear instrument maintenance

    International Nuclear Information System (INIS)

    1991-04-01

    Proper nuclear instrument maintenance is the essential precondition for any experimental work in nuclear sciences and technology. With the rapidly increasing sophistication of nuclear instrumentation, and considering the rather specific conditions that prevail in many IAEA Member States, this topic is gaining in importance, and has a strong economic implication. There is a general opinion that a regional, and possibly interregional cooperation in the field might be advantageous, and economically beneficial to all participating parties. The experience in such cooperation is limited, but sufficient that some reliable observations can be made, some conclusion can be drawn, and some recommendation for the possible future development can be presented

  11. Physics of Strongly Coupled Plasma

    Energy Technology Data Exchange (ETDEWEB)

    Kraeft, Wolf-Dietrich [Universitat Rostock (Germany)

    2007-07-15

    Strongly coupled plasmas (or non-ideal plasmas) are multi-component charged many-particle systems, in which the mean value of the potential energy of the system is of the same order as or even higher than the mean value of the kinetic energy. The constituents are electrons, ions, atoms and molecules. Dusty (or complex) plasmas contain still mesoscopic (multiply charged) particles. In such systems, the effects of strong coupling (non-ideality) lead to considerable deviations of physical properties from the corresponding properties of ideal plasmas, i.e., of plasmas in which the mean kinetic energy is essentially larger than the mean potential energy. For instance, bound state energies become density dependent and vanish at higher densities (Mott effect) due to the interaction of the pair with the surrounding particles. Non-ideal plasmas are of interest both for general scientific reasons (including, for example, astrophysical questions), and for technical applications such as inertially confined fusion. In spite of great efforts both experimentally and theoretically, satisfactory information on the physical properties of strongly coupled plasmas is not at hand for any temperature and density. For example, the theoretical description of non-ideal plasmas is possible only at low densities/high temperatures and at extremely high densities (high degeneracy). For intermediate degeneracy, however, numerical experiments have to fill the gap. Experiments are difficult in the region of 'warm dense matter'. The monograph tries to present the state of the art concerning both theoretical and experimental attempts. It mainly includes results of the work performed in famous Russian laboratories in recent decades. After outlining basic concepts (chapter 1), the generation of plasmas is considered (chapter 2, chapter 3). Questions of partial (chapter 4) and full ionization (chapter 5) are discussed including Mott transition and Wigner crystallization. Electrical and

    The structures and motions of quasi-2-dimensional strongly coupled dust Coulomb clusters with particle number N from few to hundreds in a cylindrical rf plasma trap are studied and compared with the results from the molecular dynamic simulation using more ideal models. Shell structures with periodic packing in different shells and intershell rotational motion dominated excitations are observed at small N. As N increases, the boundary has less effect, the system recovers to the triangular lattice with isotropic vortex type cooperative excitations similar to an infinite N system except the outer shell region. The above generic behaviors are mainly determined by the system symmetry and agree with the simulation results. The detailed interaction form causes minor effect such as the fine structure of packing

  13. Probability densities in strong turbulence

    Yakhot, Victor

    2006-03-01

    In this work we, using Mellin’s transform combined with the Gaussian large-scale boundary condition, calculate probability densities (PDFs) of velocity increments P(δu,r), velocity derivatives P(u,r) and the PDF of the fluctuating dissipation scales Q(η,Re), where Re is the large-scale Reynolds number. The resulting expressions strongly deviate from the Log-normal PDF P(δu,r) often quoted in the literature. It is shown that the probability density of the small-scale velocity fluctuations includes information about the large (integral) scale dynamics which is responsible for the deviation of P(δu,r) from P(δu,r). An expression for the function D(h) of the multifractal theory, free from spurious logarithms recently discussed in [U. Frisch, M. Martins Afonso, A. Mazzino, V. Yakhot, J. Fluid Mech. 542 (2005) 97] is also obtained.

    Full Text Available The objective of this study was to compare the perceptions of two families living in two different neighborhoods (rated according to risk levels regarding social support. A questionnaire was designed to assess social support according to the following dimensions: instrumental, emotional, religious, and support from friends, neighbors and family. The sample was comprised as follows: considering the 114 families living in neighborhood 1, 52 families were interviewed; and among the 162 families living in neighborhood 2, 60 families were interviewed. No significant difference was found related to instrumental, religious and emotional support, including the support from relatives among the families from both neighborhoods. The results disagree with the reviewed literature, which indicated a strong association between social support and families living at socioeconomic risk. In conclusion, social support is important for families, regardless of their risk stratification.

    1980-01-01

    The methods for measuring radiation are shortly reviewed. The instrumentation for neutron flux measurement is classified into out-of-core and in-core instrumentation. The out-of-core instrumentation monitors the operational range from the subcritical reactor to full power. This large range is covered by several measurement channels which derive their signals from counter tubes and ionization chambers. The in-core instrumentation provides more detailed information on the power distribution in the core. The self-powered neutron detectors and the aeroball system in PWR reactors are discussed. Temperature and pressure measurement devices are briefly discussed. The different methods for leak detection are described. In concluding the plant instrumentation part some new monitoring systems and analysis methods are presented: early failure detection methods by noise analysis, acoustic monitoring and vibration monitoring. The presentation of the control starts from an qualitative assessment of the reactor dynamics. The chosen control strategy leads to the definition of the part-load diagram, which provides the set-points for the different control systems. The tasks and the functions of these control systems are described. In additiion to the control, a number of limiting systems is employed to keep the reactor in a safe operating region. Finally, an outlook is given on future developments in control, concerning mainly the increased application of process computers. (orig./RW)

  16. Instrumental analysis, second edition

    International Nuclear Information System (INIS)

    Christian, G.D.; O'Reilly, J.E.

    1988-01-01

    The second edition of Instrumental Analysis is a survey of the major instrument-based methods of chemical analysis. It appears to be aimed at undergraduates but would be equally useful in a graduate course. The volume explores all of the classical quantitative methods and contains sections on techniques that usually are not included in a semester course in instrumentation (such as electron spectroscopy and the kinetic methods). Adequate coverage of all of the methods contained in this book would require several semesters of focused study. The 25 chapters were written by different authors, yet the style throughout the book is more uniform than in the earlier edition. With the exception of a two-chapter course in analog and digital circuits, the book purports to de-emphasize instrumentation, focusing more on the theory behind the methods and the application of the methods to analytical problems. However, a detailed analysis of the instruments used in each method is by no means absent. The book has the favor of a user's guide to analysis

    In the last few years a much greater emphasis has been placed upon understanding, controlling and monitoring the environmental effects of the advancing technologies. This has resulted in rapid advances in techniques for environmental monitoring. To aid the concerned scientist in keeping abreast of these developments, the Lawrence Berkeley Laboratory publishes a collection of volumes entitled Instrumentation for Environmental Monitoring. Separated into four volumes covering four media, AIR, WATER, RADIATION, and BIOMEDICAL, they provide a source book for three types of material: (1) Monitoring Rationale. They describe the characteristics, forms, and effects of a wide variety of pollutants and the means of controlling them. Federal regulations are explained and summarized. (2) Analytical Techniques. Methods of determining specific pollutants are described with special emphasis on the principles that form the basis of instrumental methods. (3) Commercial Instrumentation. The features of most commercially available instrumentation used for the determination and monitoring of each pollutant are presented in a manner that facilitates instrumental comparisons. Examples of the types of material in the volumes and the use of the volumes are presented

    Economic instruments for the implementation of environmental policies distinguish themselves from traditional tools (the 'command and control' type) for the reason that: they influence the costs and the benefits of the economic agents in question; they change the behaviour of the subjects in question in a way that they guarantee behaviour trends less harmful to the environment; they guarantee the assignment of adequate prices to the natural resources that traditionally don't have a price and therefore are consumed excessively by the economic subjects; normally they impose the transfer of economic resources to the disadvantage of the subjects responsible for the phenomena of pollution; certain objective pollution reduction data guarantee the minimization of the social costs of pollution abatement, that is, of the total costs on the economic system in general (economists define this characteristic as the 'static efficiency'); they guarantee what is called in economical jargon, the dynamic efficiency, i.e., in practice, they determine a continuous incentive for the reduction of the emission of the various pollutants and for the realization of the technological innovations that are able to control the pollution; they are more flexible than the instruments of direct regulation, because they leave the subjects a freedom of choice under different price conditions than in the past; they are flexible as well for the reason that the public operator can intervene rapidly to change the way of application

    The use of video equipment as instrumentation has been increasing steadily over the past decade. An indication of this trend can be found close to home: notice how rapidly the number of television (TV) displays has grown at our technical exhibits. It is this exhibited equipment and other equipment like it which form the subject of this summary. We will limit our discussions to readily available hardware (and a little software) and leave reports of the leading edge development work to other issues of this journal. We hope, in this manner, to present useful information to those who need to apply video to their instrumen-tation problems now. Along the way we will occasionally indicate what equipment might soon result from current research, but our clear emphasis will be on the state of the art of accessible instrumentation video.

    The Aethalometer is an instrument that provides a real-time readout of the concentration of “Black” or “Elemental” carbon aerosol particles (BC or E) in an air stream (see Figure 1 and Figure 2). It is a self-contained instrument that measures the rate of change of optical transmission through a spot on a filter where aerosol is being continuously collected and uses the information to calculate the concentration of optically absorbing material in the sampled air stream. The instrument measures the transmitted light intensities through the “sensing” portion of the filter, on which the aerosol spot is being collected, and a “reference” portion of the filter as a check on the stability of the optical source. A mass flowmeter monitors the sample air flow rate. The data from these three measurements is used to determine the mean BC content of the air stream.

But the issuers remain companies incorporated under Company Law of 1990. Such dual regulations need increased attention in order to observe the legal status of the issuers/companies and financial instruments/shares. Romanian legislator has chosen to implement in Capital Market Law special rules regarding the administration of the issuers of financial instruments, not only rules regarding admitting and maintaining to a regulated market.

    2011-01-01

    Virtual Sensor Test Instrumentation is based on the concept of smart sensor technology for testing with intelligence needed to perform sell-diagnosis of health, and to participate in a hierarchy of health determination at sensor, process, and system levels. A virtual sensor test instrumentation consists of five elements: (1) a common sensor interface, (2) microprocessor, (3) wireless interface, (4) signal conditioning and ADC/DAC (analog-to-digital conversion/ digital-to-analog conversion), and (5) onboard EEPROM (electrically erasable programmable read-only memory) for metadata storage and executable software to create powerful, scalable, reconfigurable, and reliable embedded and distributed test instruments. In order to maximize the efficient data conversion through the smart sensor node, plug-and-play functionality is required to interface with traditional sensors to enhance their identity and capabilities for data processing and communications. Virtual sensor test instrumentation can be accessible wirelessly via a Network Capable Application Processor (NCAP) or a Smart Transducer Interlace Module (STIM) that may be managed under real-time rule engines for mission-critical applications. The transducer senses the physical quantity being measured and converts it into an electrical signal. The signal is fed to an A/D converter, and is ready for use by the processor to execute functional transformation based on the sensor characteristics stored in a Transducer Electronic Data Sheet (TEDS). Virtual sensor test instrumentation is built upon an open-system architecture with standardized protocol modules/stacks to interface with industry standards and commonly used software. One major benefit for deploying the virtual sensor test instrumentation is the ability, through a plug-and-play common interface, to convert raw sensor data in either analog or digital form, to an IEEE 1451 standard-based smart sensor, which has instructions to program sensors for a wide variety of

    A spectroelectrochemical instrument has been developed for measuring the total organic carbon (TOC) content of an aqueous solution. Measurements of TOC are frequently performed in environmental, clinical, and industrial settings. Until now, techniques for performing such measurements have included, various ly, the use of hazardous reagents, ultraviolet light, or ovens, to promote reactions in which the carbon contents are oxidized. The instrument now being developed is intended to be a safer, more economical means of oxidizing organic carbon and determining the TOC levels of aqueous solutions and for providing a low power/mass unit for use in planetary missions.

    A fire at a nuclear power plant (NPP) has the potential to damage structures, systems, and components important to safety, if not promptly detected and suppressed. At Browns Ferry Nuclear Power Plant on March 22, 1975, a fire in the reactor building damaged electrical power and control systems. Damage to instrumentation cables impeded the function of both normal and standby reactor coolant systems, and degraded the operators’ plant monitoring capability. This event resulted in additional NRC involvement with utilities to ensure that NPPs are properly protected from fire as intended by the NRC principle design criteria (i.e., general design criteria 3, Fire Protection). Current guidance and methods for both deterministic and performance based approaches typically make conservative (bounding) assumptions regarding the fire-induced failure modes of instrumentation cables and those failure modes effects on component and system response. Numerous fire testing programs have been conducted in the past to evaluate the failure modes and effects of electrical cables exposed to severe thermal conditions. However, that testing has primarily focused on control circuits with only a limited number of tests performed on instrumentation circuits. In 2001, the Nuclear Energy Institute (NEI) and the Electric Power Research Institute (EPRI) conducted a series of cable fire tests designed to address specific aspects of the cable failure and circuit fault issues of concern1. The NRC was invited to observe and participate in that program. The NRC sponsored Sandia National Laboratories to support this participation, whom among other things, added a 4-20 mA instrumentation circuit and instrumentation cabling to six of the tests. Although limited, one insight drawn from those instrumentation circuits tests was that the failure characteristics appeared to depend on the cable insulation material. The results showed that for thermoset insulated cables, the instrument reading tended to drift

  13. Remnants of strong tidal interactions

    International Nuclear Information System (INIS)

    Mcglynn, T.A.

    1990-01-01

    This paper examines the properties of stellar systems that have recently undergone a strong tidal shock, i.e., a shock which removes a significant fraction of the particles in the system, and where the shocked system has a much smaller mass than the producer of the tidal field. N-body calculations of King models shocked in a variety of ways are performed, and the consequences of the shocks are investigated. The results confirm the prediction of Jaffe for shocked systems. Several models are also run where the tidal forces on the system are constant, simulating a circular orbit around a primary, and the development of tidal radii under these static conditions appears to be a mild process which does not dramatically affect material that is not stripped. The tidal radii are about twice as large as classical formulas would predict. Remnant density profiles are compared with a sample of elliptical galaxies, and the implications of the results for the development of stellar populations and galaxies are considered. 38 refs

    Our friend and colleague John Strong was cruelly taken from us by a brain tumour on 31 July, a few days before his 65th birthday. John started his career and obtained his PhD in a group from Westfield College, initially working on experiments at Rutherford Appleton Laboratory (RAL). From the early 1970s onwards, however, his research was focused on experiments in CERN, with several particularly notable contributions. The Omega spectrometer adopted a system John had originally developed for experiments at RAL using vidicon cameras (a type of television camera) to record the sparks in the spark chambers. This highly automated system allowed Omega to be used in a similar way to bubble chambers. He contributed to the success of NA1 and NA7, where he became heavily involved in the electronic trigger systems. In these experiments the Westfield group joined forces with Italian colleagues to measure the form factors of the pion and the kaon, and the lifetime of some of the newly discovered charm particles.

  16. Analysis and Synthesis of Musical Instrument Sounds

    Science.gov (United States)

    Beauchamp, James W.

    For synthesizing a wide variety of musical sounds, it is important to understand which acoustic properties of musical instrument sounds are related to specific perceptual features. Some properties are obvious: Amplitude and fundamental frequency easily control loudness and pitch. Other perceptual features are related to sound spectra and how they vary with time. For example, tonal "brightness" is strongly connected to the centroid or tilt of a spectrum. "Attack impact" (sometimes called "bite" or "attack sharpness") is strongly connected to spectral features during the first 20-100 ms of sound, as well as the rise time of the sound. Tonal "warmth" is connected to spectral features such as "incoherence" or "inharmonicity."

  17. Strongly interacting photons and atoms

    International Nuclear Information System (INIS)

    Alge, W.

    1999-05-01

    This thesis contains the main results of the research topics I have pursued during the my PhD studies at the University of Innsbruck and partly in collaboration with the Institut d' Optique in Orsay, France. It is divided into three parts. The first and largest part discusses the possibility of using strong standing waves as a tool to cool and trap neutral atoms in optical cavities. This is very important in the field of nonlinear optics where several successful experiments with cold atoms in cavities have been performed recently. A discussion of the optical parametric oscillator in a regime where the nonlinearity dominates the evolution is the topic of the second part. We investigated mainly the statistical properties of the cavity output of the three interactive cavity modes. Very recently a system has been proposed which promises fantastic properties. It should exhibit a giant Kerr nonlinearity with negligible absorption thus leading to a photonic turnstile device based on cold atoms in cavity. We have shown that this model suffers from overly simplistic assumptions and developed several more comprehensive approaches to study the behavior of this system. Apart from the division into three parts of different contents the thesis is divided into publications, supplements and invisible stuff. The intention of the supplements is to reach researchers which work in related areas and provide them with more detailed information about the concepts and the numerical tools we used. It is written especially for diploma and PhD students to give them a chance to use the third part of our work which is actually the largest one. They consist of a large number of computer programs we wrote to investigate the behavior of the systems in parameter regions where no hope exists to solve the equations analytically. (author)

  18. Topics in strong Langmuir turbulence

    International Nuclear Information System (INIS)

    Skoric, M.M.

    1981-01-01

    This thesis discusses certain aspects of the turbulence of a fully ionised non-isothermal plasma dominated by the Langmuir mode. Some of the basic properties of strongly turbulent plasmas are reviewed. In particular, interest is focused on the state of Langmuir turbulence, that is the turbulence of a simple externally unmagnetized plasma. The problem of the existence and dynamics of Langmuir collapse is discussed, often met as a non-linear stage of the modulational instability in the framework of the Zakharov equations (i.e. simple time-averaged dynamical equations). Possible macroscopic consequences of such dynamical turbulent models are investigated. In order to study highly non-linear collapse dynamics in its advanced stage, a set of generalized Zakharov equations are derived. Going beyond the original approximation, the author includes the effects of higher electron non-linearities and a breakdown of slow-timescale quasi-neutrality. He investigates how these corrections may influence the collapse stabilisation. Recently, it has been realised that the modulational instability in a Langmuir plasma will be accompanied by the collisionless-generation of a slow-timescale magnetic field. Accordingly, a novel physical situation has emerged which is investigated in detail. The stability of monochromatic Langmuir waves in a self-magnetized Langmuir plasma, is discussed, and the existence of a novel magneto-modulational instability shown. The wave collapse dynamics is investigated and a physical interpretation of the basic results is given. A problem of the transient analysis of an interaction of time-dependent electromagnetic pulses with linear cold plasma media is investigated. (Auth.)

  19. Promoting Strong Written Communication Skills

    2015-12-01

    The reason that an improvement in the quality of technical writing is still needed in the classroom is due to the fact that universities are facing challenging problems not only on the technological front but also on the socio-economic front. The universities are actively responding to the changes that are taking place in the global consumer marketplace. Obviously, there are numerous benefits of promoting strong written communication skills. They can be summarized into the following six categories. First, and perhaps the most important: The University achieves learner satisfaction. The learner has documented verbally, that the necessary knowledge has been successfully acquired. This results in learner loyalty that in turn will attract more qualified learners.Second, quality communication lowers the cost per pupil, consequently resulting in increased productivity backed by a stronger economic structure and forecast. Third, quality communications help to improve the cash flow and cash reserves of the university. Fourth, having high quality communication enables the university to justify the need for high costs of tuition and fees. Fifth, better quality in written communication skills result in attracting top-quality learners. This will lead to happier and satisfied learners, not to mention greater prosperity for the university as a whole. Sixth, quality written communication skills result in reduced complaints, thus meaning fewer hours spent on answering or correcting the situation. The University faculty and staff are thus able to devote more time on scholarly activities, meaningful research and productive community service. References Boyer, Ernest L. (1990).

    2016-03-01

    The Integrating Nephelometer (Figure 1) is an instrument that measures aerosol light scattering. It measures aerosol optical scattering properties by detecting (with a wide angular integration – from 7 to 170°) the light scattered by the aerosol and subtracting the light scattered by the carrier gas, the instrument walls and the background noise in the detector (zeroing). Zeroing is typically performed for 5 minutes every day at midnight UTC. The scattered light is split into red (700 nm), green (550 nm), and blue (450 nm) wavelengths and captured by three photomultiplier tubes. The instrument can measure total scatter as well as backscatter only (from 90 to 170°) (Heintzenberg and Charlson 1996; Anderson et al. 1996; Anderson and Ogren 1998; TSI 3563 2015) At ARM (Atmospheric Radiation Measurement), two identical Nephelometers are usually run in series with a sample relative humidity (RH) conditioner between them. This is possible because Nephelometer sampling is non-destructive and the sample can be passed on to another instrument. The sample RH conditioner scans through multiple RH values in cycles, treating the sample. This kind of setup allows to study how aerosol particles’ light scattering properties are affected by humidification (Anderson et al. 1996). For historical reasons, the two Nephelometers in this setup are labeled “wet” and “dry”, with the “dry” Nephelometer usually being the one before the conditioner and sampling ambient air (the names are switched for the MAOS measurement site due to the high RH of the ambient air).

    An auto-ranging AC resistance measuring instrument for remote measurement of the resistance of an electrical device or circuit connected to the instrument includes a signal generator which generates an AC excitation signal for application to a load, including the device and the transmission line, a monitoring circuit which provides a digitally encoded signal representing the voltage across the load, and a microprocessor which operates under program control to provide an auto-ranging function by which range resistance is connected in circuit with the load to limit the load voltage to an acceptable range for the instrument, and an auto-compensating function by which compensating capacitance is connected in shunt with the range resistance to compensate for the effects of line capacitance. After the auto-ranging and auto-compensation functions are complete, the microprocessor calculates the resistance of the load from the selected range resistance, the excitation signal, and the load voltage signal, and displays of the measured resistance on a digital display of the instrument. 8 figs.

    Knuth, Kevin H.; Erner, Philip M.; Frasso, Scott

    2007-11-01

    Remote science operations require automated systems that can both act and react with minimal human intervention. One such vision is that of an intelligent instrument that collects data in an automated fashion, and based on what it learns, decides which new measurements to take. This innovation implements experimental design and unites it with data analysis in such a way that it completes the cycle of learning. This cycle is the basis of the Scientific Method. The three basic steps of this cycle are hypothesis generation, inquiry, and inference. Hypothesis generation is implemented by artificially supplying the instrument with a parameterized set of possible hypotheses that might be used to describe the physical system. The act of inquiry is handled by an inquiry engine that relies on Bayesian adaptive exploration where the optimal experiment is chosen as the one which maximizes the expected information gain. The inference engine is implemented using the nested sampling algorithm, which provides the inquiry engine with a set of posterior samples from which the expected information gain can be estimated. With these computational structures in place, the instrument will refine its hypotheses, and repeat the learning cycle by taking measurements until the system under study is described within a pre-specified tolerance. We will demonstrate our first attempts toward achieving this goal with an intelligent instrument constructed using the LEGO MINDSTORMS NXT robotics platform.

    Recognizing that the University Reactor Instrumentation Program was developed in response to widespread needs in the academic community for modernization and improvement of research and training reactors at institutions such as the University of Florida, the items proposed to be supported by this grant over its two year period have been selected as those most likely to reduce foreed outages, to meet regulatory concerns that had been expressed in recent years by Nuclear Regulatory Commission inspectors or to correct other facility problems and limitations. Department of Energy Grant Number DE-FG07-90ER129969 was provided to the University of Florida Training Reactor(UFTR) facility through the US Department of Energy's University Reactor Instrumentation Program. The original proposal submitted in February, 1990 requested support for UFTR facility instrumentation and equipment upgrades for seven items in the amount of $107,530 with $13,800 of this amount to be the subject of cost sharing by the University of Florida and $93,730 requested as support from the Department of Energy. A breakdown of the items requested and total cost for the proposed UFTR facility instrumentation and equipment improvements is presented

  13. The Role of Social Assistance on Effectiveness of Social Rights

    Directory of Open Access Journals (Sweden)

    2016-10-01

    Full Text Available The social assistance has intrinsic historical, legal and political relationship to social rights. Fundamental rights have assumed a legal-constitutional role since the mid-twentieth century. Through historical and doctrinal review of fundamental rights and social welfare, the identification of legal frameworks and institutional instruments of social assistance that demonstrate their ability to contribute to the realization of social rights and the problem of realization of social rights, social assistance seems to be able to play a prominent role as a public policy that helps to point out a solution to the problem of lack of effectiveness of social rights.

  14. Spring/dimple instrument tube restraint

    Science.gov (United States)

    DeMario, E.E.; Lawson, C.N.

    1993-11-23

    A nuclear fuel assembly for a pressurized water nuclear reactor has a spring and dimple structure formed in a non-radioactive insert tube placed in the top of a sensor receiving instrumentation tube thimble disposed in the fuel assembly and attached at a top nozzle, a bottom nozzle, and intermediate grids. The instrumentation tube thimble is open at the top, where the sensor or its connection extends through the cooling water for coupling to a sensor signal processor. The spring and dimple insert tube is mounted within the instrumentation tube thimble and extends downwardly adjacent the top. The springs and dimples restrain the sensor and its connections against lateral displacement causing impact with the instrumentation tube thimble due to the strong axial flow of cooling water. The instrumentation tube has a stainless steel outer sleeve and a zirconium alloy inner sleeve below the insert tube adjacent the top. The insert tube is relatively non-radioactivated inconel alloy. The opposed springs and dimples are formed on diametrically opposite inner walls of the insert tube, the springs being formed as spaced axial cuts in the insert tube, with a web of the insert tube between the cuts bowed radially inwardly for forming the spring, and the dimples being formed as radially inward protrusions opposed to the springs. 7 figures.

    Fisher, J. Richard; Warnick, Karl F.; Jeffs, Brian D.; Norrod, Roger D.; Lockman, Felix J.; Cordes, James M.; Giovanelli, Riccardo

    2009-03-01

    This white paper offers cautionary observations about the planning and development of new, large radio astronomy instruments. Complexity is a strong cost driver so every effort should be made to assign differing science requirements to different instruments and probably different sites. The appeal of shared resources is generally not realized in practice and can often be counterproductive. Instrument optimization is much more difficult with longer lists of requirements, and the development process is longer and less efficient. More complex instruments are necessarily further behind the technology state of the art because of longer development times. Including technology R&D in the construction phase of projects is a growing trend that leads to higher risks, cost overruns, schedule delays, and project de-scoping. There are no technology breakthroughs just over the horizon that will suddenly bring down the cost of collecting area. Advances come largely through careful attention to detail in the adoption of new technology provided by industry and the commercial market. Radio astronomy instrumentation has a very bright future, but a vigorous long-term R&D program not tied directly to specific projects needs to be restored, fostered, and preserved.

  16. Database for earthquake strong motion studies in Italy

    Scasserra, G.; Stewart, J.P.; Kayen, R.E.; Lanzo, G.

    2009-01-01

    We describe an Italian database of strong ground motion recordings and databanks delineating conditions at the instrument sites and characteristics of the seismic sources. The strong motion database consists of 247 corrected recordings from 89 earthquakes and 101 recording stations. Uncorrected recordings were drawn from public web sites and processed on a record-by-record basis using a procedure utilized in the Next-Generation Attenuation (NGA) project to remove instrument resonances, minimize noise effects through low- and high-pass filtering, and baseline correction. The number of available uncorrected recordings was reduced by 52% (mostly because of s-triggers) to arrive at the 247 recordings in the database. The site databank includes for every recording site the surface geology, a measurement or estimate of average shear wave velocity in the upper 30 m (Vs30), and information on instrument housing. Of the 89 sites, 39 have on-site velocity measurements (17 of which were performed as part of this study using SASW techniques). For remaining sites, we estimate Vs30 based on measurements on similar geologic conditions where available. Where no local velocity measurements are available, correlations with surface geology are used. Source parameters are drawn from databanks maintained (and recently updated) by Istituto Nazionale di Geofisica e Vulcanologia and include hypocenter location and magnitude for small events (M< ??? 5.5) and finite source parameters for larger events. ?? 2009 A.S.

    Netherlands Hydrological Modeling Instrument A decision support system for water basin management. J.C. Hoogewoud , W.J. de Lange ,A. Veldhuizen , G. Prinsen , The Netherlands Hydrological modeling Instrument (NHI) is the center point of a framework of models, to coherently model the hydrological system and the multitude of functions it supports. Dutch hydrological institutes Deltares, Alterra, Netherlands Environmental Assessment Agency, RWS Waterdienst, STOWA and Vewin are cooperating in enhancing the NHI for adequate decision support. The instrument is used by three different ministries involved in national water policy matters, for instance the WFD, drought management, manure policy and climate change issues. The basis of the modeling instrument is a state-of-the-art on-line coupling of the groundwater system (MODFLOW), the unsaturated zone (metaSWAP) and the surface water system (MOZART-DM). It brings together hydro(geo)logical processes from the column to the basin scale, ranging from 250x250m plots to the river Rhine and includes salt water flow. The NHI is validated with an eight year run (1998-2006) with dry and wet periods. For this run different parts of the hydrology have been compared with measurements. For instance, water demands in dry periods (e.g. for irrigation), discharges at outlets, groundwater levels and evaporation. A validation alone is not enough to get support from stakeholders. Involvement from stakeholders in the modeling process is needed. There fore to gain sufficient support and trust in the instrument on different (policy) levels a couple of actions have been taken: 1. a transparent evaluation of modeling-results has been set up 2. an extensive program is running to cooperate with regional waterboards and suppliers of drinking water in improving the NHI 3. sharing (hydrological) data via newly setup Modeling Database for local and national models 4. Enhancing the NHI with "local" information. The NHI is and has been used for many

  18. Strong profiling is not mathematically optimal for discovering rare malfeasors

    Energy Technology Data Exchange (ETDEWEB)

    Press, William H [Los Alamos National Laboratory

    2008-01-01

    In a large population of individuals labeled j = 1,2,...,N, governments attempt to find the rare malfeasor j = j, (terrorist, for example) by making use of priors p{sub j} that estimate the probability of individual j being a malfeasor. Societal resources for secondary random screening such as airport search or police investigation are concentrated against individuals with the largest priors. They may call this 'strong profiling' if the concentration is at least proportional to p{sub j} for the largest values. Strong profiling often results in higher probability, but otherwise innocent, individuals being repeatedly subjected to screening. They show here that, entirely apart from considerations of social policy, strong profiling is not mathematically optimal at finding malfeasors. Even if prior probabilities were accurate, their optimal use would be only as roughly the geometric mean between a strong profiling and a completely uniform sampling of the population.

    The Ultraviolet and Visible Imagers and Spectrographic Imagers (UVISI) instrument is a complex of nine sensor units (five spectrographic imagers and four imagers) and multiple processors that will provide detailed images and spectra of targets for the Midcourse Space Experiment mission. Imaging and spectroscopy each cover the range from 110 nm (far ultraviolet) to 900 nm (near infrared). UVISI is intended to investigate a multitude of celestial, atmospheric, and point sources over its planned 4-year lifetime. At 104 W and 211 kg, it is not only the largest free-flying instrument ever built at APL, but is also larger than 47 of the 55 APL-built spacecraft and more complex than many of them. This article discusses the specifications of UVISI and its hardware and software features. It also attempts to give the reader a sense of the design trade-offs made during UVISI development that resulted in its present configuration.

    Reference is made to the instrumentation of liquid metal cooled fast reactors. In order to ensure the safe operation of such reactors it is necessary to constantly monitor the coolant flowing through the fuel assemblies for temperature and rate of flow, requiring a large number of sensors. An improved and simplified arrangement is claimed in which the fuel assemblies feed a fraction of coolant to three instrument units arranged to sense the temperature and rate of flow of samples of coolant. Each instrument unit comprises a sleeve housing a sensing unit and has a number of inlet ducts arranged for receiving coolant from a fuel assembly together with a single outlet. The sensing unit has three thermocouple hot junctions connected in series, the hot junctions and inlet ducts being arranged in pairs. Electromagnetic windings around an inductive core are arranged to sense variation in flow of liquid metal by flux distortion. Fission product sensing means may also be provided. Full constructional details are given. (U.K.)

    This Technology Status Report describes research and accomplishments for the Instrumentation and Diagnostics (I D) Projects within the Advanced Research and Technology Development (AR TD) Program of the United States Department of Energy (DOE) Office of Fossil Energy (FE). Process understanding and control can be improved through the development of advanced instrumentation and diagnostics. The thrust of the I D Projects is to further develop existing measurement and control techniques for application to advanced coal-based technologies. Project highlights are: an inductively coupled plasma (ICP) instrument has been developed to analyze trace elements in gasification and combustion process streams. An in situ two-color Mie scattering technique with LSS can simultaneously measure the size, velocity, and elemental composition of coal particles during combustion. A high-temperature, fluorescence thermometry technique has accurately measured gas temperatures during field testing in combustion and gasification environments. Expert systems have been developed to improve the control of advanced coal-based processes. Capacitance flowmeters were developed to determine the mass flowrate, solid volume fraction, and particle velocities of coal slurries. 32 refs., 9 figs.

    Cohen, David J.; Rossing, Thomas D.

    The mandolin family of instruments consists of plucked chordophones, each having eight strings in four double courses. With the exception of the mandobass, the courses are tuned in intervals of fifths, as are the strings in violin family instruments. The soprano member of the family is the mandolin, tuned G3-D4-A4-E5. The alto member of the family is the mandola, tuned C3-G3-D4-A4. The mandola is usually referred to simply as the mandola in the USA, but is called the tenor mandola in Europe. The tenor member of the family is the octave mandolin, tuned G2-D3-A3-E4. It is referred to as the octave mandolin in the USA, and as the octave mandola in Europe. The baritone member of the family is the mandocello, or mandoloncello, tuned C2-G2-D3-A3. A variant of the mandocello not common in the USA is the five-course liuto moderno, or simply liuto, designed for solo repertoire. Its courses are tuned C2-G2-D3-A3-E4. A mandobass was also made by more than one manufacturer during the early twentieth century, though none are manufactured today. They were fretted instruments with single string courses tuned E1-A1-D2-G2. There are currently a few luthiers making piccolo mandolins, tuned C4-G4-D5-A5.

    The MEMS strong motion seismograph we developed used the modularization method to design its software and hardware.It can fit various needs in different application situation.The hardware of the instrument is composed of a MEMS accelerometer,a control processor system,a data-storage system,a wired real-time data transmission system by IP network,a wireless data transmission module by 3G broadband,a GPS calibration module and power supply system with a large-volumn lithium battery in it. Among it,the seismograph's sensor adopted a three-axis with 14-bit high resolution and digital output MEMS accelerometer.Its noise level just reach about 99μg/√Hz and ×2g to ×8g dynamically selectable full-scale.Its output data rates from 1.56Hz to 800Hz. Its maximum current consumption is merely 165μA,and the device is so small that it is available in a 3mm×3mm×1mm QFN package. Furthermore,there is access to both low pass filtered data as well as high pass filtered data,which minimizes the data analysis required for earthquake signal detection. So,the data post-processing can be simplified. Controlling process system adopts a 32-bit low power consumption embedded ARM9 processor-S3C2440 and is based on the Linux operation system.The processor's operating clock at 400MHz.The controlling system's main memory is a 64MB SDRAM with a 256MB flash-memory.Besides,an external high-capacity SD card data memory can be easily added.So the system can meet the requirements for data acquisition,data processing,data transmission,data storage,and so on. Both wired and wireless network can satisfy remote real-time monitoring, data transmission,system maintenance,status monitoring or updating software.Linux was embedded and multi-layer designed conception was used.The code, including sensor hardware driver,the data acquisition,earthquake setting out and so on,was written on medium layer.The hardware driver consist of IIC-Bus interface driver, IO driver and asynchronous notification driver.

    2015-01-01

    Fluoride salt-cooled High temperature Reactors (FHRs) are entering into early phase engineering development. Initial candidate technologies have been identified to measure all of the required process variables. The purpose of this paper is to describe the proposed measurement techniques in sufficient detail to enable assessment of the proposed instrumentation suite and to support development of the component technologies. This paper builds upon the instrumentation chapter of the recently published FHR technology development roadmap. Locating instruments outside of the intense core radiation and high-temperature fluoride salt environment significantly decreases their environmental tolerance requirements. Under operating conditions, FHR primary coolant salt is a transparent, low-vapor-pressure liquid. Consequently, FHRs can employ standoff optical measurements from above the salt pool to assess in-vessel conditions. For example, the core outlet temperature can be measured by observing the fuel s blackbody emission. Similarly, the intensity of the core s Cerenkov glow indicates the fission power level. Short-lived activation of the primary coolant provides another means for standoff measurements of process variables. The primary coolant flow and neutron flux can be measured using gamma spectroscopy along the primary coolant piping. FHR operation entails a number of process measurements. Reactor thermal power and core reactivity are the most significant variables for process control. Thermal power can be determined by measuring the primary coolant mass flow rate and temperature rise across the core. The leading candidate technologies for primary coolant temperature measurement are Au-Pt thermocouples and Johnson noise thermometry. Clamp-on ultrasonic flow measurement, that includes high-temperature tolerant standoffs, is a potential coolant flow measurement technique. Also, the salt redox condition will be monitored as an indicator of its corrosiveness. Both

    Full Text Available In Europe, we are witnessing a growth in the social economy sector, i.e. in socio – economic organizations, which belong neither to the traditional for profit sector (market economy nor to the public sector (government (Deforuny, 2001; Young, 2007 - they rather act at the interface of civil society and markets (Jäger, 2010. The main goal of these organizations, called social enterprises or social business, is doing business for socially useful purposes. These initiatives may take the form of traditional Non-Governmental Organizations (NGOs, like foundations and associations, as well as new kinds of organizations for example social cooperatives, partnerships, funds. Social economy is situated between public and business sphere of administration and combines both, social objectives and the ones profit-oriented. Social entrepreneurship is unquestionably a desirable feature of social economy understood as reaching planned economic objectives with the use of available resources. Another feature comprises in using involvement and creativity of excluded persons and thus, solving social problems, among others, structural unemployment and disadvantage of social minorities as well as strengthening democratic processes, bottom-up social initiatives etc. Achieving objectives, both social and economic, requires using modern management instruments and methods. All of the above mentioned organizations or ventures, which achieve their local, social or ethical mission and goals using methods adopted from the business sector (Defourny, Hulgard, Pestoff, eds.2014. One of these methods is project management. The whole sector of social economy, both in Poland and in Europe, is strongly influenced by projectification process: a lot of the activities are performed in the form of projects.

    Full Text Available The social policy of any state incorporates suitable financial tools that support parents and children. In this paper, we have presented the evolution of these forms of social protection, which have changed almost yearly over the past decade. The ones that I have considered particularly important are: the allowance for raising children up to 2 years or up to 3 years in the case of disabled children and the re-induction incentive. An important instrument of reintegration in the labour market, the re-induction incentive is presented in the main financial aspects and statistically speaking, I have analyzed its evolution in numbers and total value. In the second part of the thesis I have shown the social, legislative and financial aspects of the child raising allowance.

    The past year's contribution from Dr. Kaukler's experimental effort consists of these 5 parts: a) Construction and proof-of-concept testing of a novel shearing plate viscometer designed to produce small shear rates and operate at elevated temperatures; b) Preparing nonlinear polymeric materials to serve as standards of nonlinear Theological behavior; c) Measurements and evaluation of above materials for nonlinear rheometric behavior at room temperature using commercial spinning cone and plate viscometers available in the lab; d) Preparing specimens from various forms of pitch for quantitative comparative testing in a Dynamic Mechanical Analyzer, Thermal Mechanical Analyzer; and Archeological Analyzer; e) Arranging to have sets of pitch specimens tested using the various instruments listed above, from different manufacturers, to form a baseline of the viscosity variation with temperature using the different test modes offered by these instruments by compiling the data collected from the various test results. Our focus in this project is the shear thinning behavior of ZBLAN glass over a wide range of temperature. Experimentally, there are no standard techniques to perform such measurements on glasses, particularly at elevated temperatures. Literature reviews to date have shown that shear thinning in certain glasses appears to occur, but no data is available for ZBLAN glass. The best techniques to find shear thinning behavior require the application of very low rates of shear. In addition, because the onset of the thinning behavior occurs at an unknown elevated temperature, the instruments used in this study must provide controlled low rates of shear and do so for temperatures approaching 600 C. In this regard, a novel shearing parallel plate viscometer was designed and a prototype built and tested.

    Domestic violence against women is regarded as an important health problem among women and a serious concern in issues related to human rights. To date, a few screening tools for domestic violence exist for Iranian married women, but they assess only some of the domestic violence components. The present study aimed to design and determine the validity and reliability of a screening instrument for domestic violence in a sample of Iranian women. The present study was a cross-sectional psychometric evaluation conducted on 350 married women in Ilam, Iran, in 2014. The samples were selected through multistage sampling and the main method was cluster sampling. A 20-item, self-administered questionnaire was validated by exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). An Eigen value > 1 and a loading factor > 0.3 for each component were considered as indices for extracting domestic violence components. Reliability was calculated by test-retest and Cronbach's alpha. Also, the content validity index (CVI) and content validity ratio (CVR) were used to measure content validity. The data were analyzed using SPSS-13 and LISREL 8.8 software programs. The self-administered instrument was completed by 334 women. The CFA and EFA methods confirmed embedding items and the three-factor structure of the instrument including psychological, physical, and sexual violence, which explained 66% of the total variance of the domestic violence. The ICC and Cronbach's alpha coefficients were > 0.7 for the components of the questionnaire. The test-retest also revealed strong correlations for each of the domestic violence components (r > 0.6). The used instrument for measuring domestic violence had desirable validity and reliability and can be used as a suitable instrument in health and social researches in the local population.

  2. Green and social bonds - A promising tool

    Blanc, Dominique; Barochez, Aurelie de; Cozic, Aela

    2013-11-01

    Issues of green bonds, socially responsible bonds and climate bonds are on the rise. Novethic estimates that some Euro 5 billion in such bonds has been issued since the start of 2013 by development banks, the main issuers of this type of debt. The figure is equal to over half of their total issues since 2007. Including local authorities, corporations and banks, a total Euro 8 billion of these bonds has been issued thus far in 2013. Given the size of the bond market, which the OECD estimated at Euro 95,000 billion in 2011, green and social bonds are still something of a niche but have strong growth potential. A number of large issues, from Euro 500 million to Euro 1 billion, were announced at the end of the year. Unlike conventional bonds, green and social bonds are not intended to finance all the activities of the issuer or refinance its debt. They serve instead to finance specific projects, such as producing renewable energy or adapting to climate change, the risk of which is shouldered by the issuer. This makes them an innovative instrument, used to earmark investments in projects with a direct environmental or social benefit rather than simply on the basis of the issuer's sustainable development policy. With financing being sought for the ecological transition, green and social bonds are promising instruments, sketching out at global level the shape of tools adapted to the financing of a green economy. On the strength of these advantages, the interest of responsible investors - the main target of green and social bond issuers - is growing fast. Judging by issuer press releases and the most commonly used currencies, the main subscribers today are US investors, among them CalSTRS and fund managers like Calvert Investment Management and Trillium Asset Management. European asset owners are also starting to focus on green and social bonds. A Novethic survey shows that 13% of them have already subscribed to such an issue or plan to do so. The present study

    2012-07-01

    The Q/U Imaging ExperimenT (QUIET) is designed to measure polarization in the Cosmic Microwave Background, targeting the imprint of inflationary gravitational waves at large angular scales ({approx}1{sup o}). Between 2008 October and 2010 December, two independent receiver arrays were deployed sequentially on a 1.4m side-fed Dragonian telescope. The polarimeters which form the focal planes use a highly compact design based on High Electron Mobility Transistors (HEMTs) that provides simultaneous measurements of the Stokes parameters Q, U, and I in a single module. The 17-element Q-band polarimeter array, with a central frequency of 43.1 GHz, has the best sensitivity (69 {mu}Ks{sup 1/2}) and the lowest instrumental systematic errors ever achieved in this band, contributing to the tensor-to-scalar ratio at r < 0:1. The 84-element W-band polarimeter array has a sensitivity of 87 {mu}Ks{sup 1/2} at a central frequency of 94.5 GHz. It has the lowest systematic errors to date, contributing at r < 0:01. The two arrays together cover multipoles in the range {ell} {approx} 25 -- 975. These are the largest HEMT-based arrays deployed to date. This article describes the design, calibration, performance of, and sources of systematic error for the instrument.

    The Instrument Remote Control (IRC) project ongoing at NASA's Goddard Space Flight Center's (GSFC) Information Systems Center (ISC) supports NASA's mission by defining an adaptive intranet-based framework that provides robust interactive and distributed control and monitoring of remote instruments. An astronomical IRC architecture that combines the platform-independent processing capabilities of Java with the power of Extensible Markup Language (XML) to express hierarchical data in an equally platform-independent, as well as human readable manner, has been developed. This architecture is implemented using a variety of XML support tools and Application Programming Interfaces (API) written in Java. IRC will enable trusted astronomers from around the world to easily access infrared instruments (e.g., telescopes, cameras, and spectrometers) located in remote, inhospitable environments, such as the South Pole, a high Chilean mountaintop, or an airborne observatory aboard a Boeing 747. Using IRC's frameworks, an astronomer or other scientist can easily define the type of onboard instrument, control the instrument remotely, and return monitoring data all through the intranet. The Astronomical Instrument Markup Language (AIML) is the first implementation of the more general Instrument Markup Language (IML). The key aspects of our approach to instrument description and control applies to many domains, from medical instruments to machine assembly lines. The concepts behind AIML apply equally well to the description and control of instruments in general. IRC enables us to apply our techniques to several instruments, preferably from different observatories.

    A study is being carried out using a surrogate vibro-packed fuel pin with micro-spheres of two different sizes to get the density distribution by gamma transmission technique. A shielded (with 2 mm slit of ∼ 2''SS collimator) LaBr scintillation detector is used as the detector system. A strong 137 Cs source is used as the source. The source strength as it is transmitted through the fuel pin is measured by the scintillation detector. The entire length of the fuel pin is gradually moved up from one end to other end and the detector is allowed to continuously examine the transmission profile of the fuel pin. The instrumentation for the fuel pin scanner has been developed and is integrated with the system. The instrumentation includes microcontroller based motor control system and customized detector pulse counting systems. The systems are interfaced to a computer through serial communication.

    The Astronomical Instrumentation System Markup Language (AISML) is an Extensible Markup Language (XML) based file format for maintaining and exchanging information about astronomical instrumentation. The factors behind the need for an AISML are first discussed followed by the reasons why XML was chosen as the format. Next it's shown how XML also provides the framework for a more precise definition of an astronomical instrument and how these instruments can be combined to form an Astronomical Instrumentation System (AIS). AISML files for several instruments as well as one for a sample AIS are provided. The files demonstrate how AISML can be utilized for various tasks from web page generation and programming interface to instrument maintenance and quality management. The advantages of widespread adoption of AISML are discussed.

    1985-01-01

    The Fusion Materials Irradiation Test facility (FMIT) cw prototype accelerator has noninterceptive beamline instrumentation to measure beam parameters. The transverse emittances and beam profiles are measured with an array of photodiode sensors viewing light emitted from the beam region. Tomographic reconstructions of both spatial-density distributions and of transverse-emittance distributions are performed throughout a quadrupole focusing section. Beam bunches passing through capacitive probes produce bipolar waveforms whose zero crossing corresponds to the bunch's longitudinal centroid. By measuring the time required for a bunch to travel the known distance between two probes, velocity and energy are determined. A toroidal transformer measures the average ac beam current. Beam spill is measured by a set of movable jaws that intercept the beam edges. Each jaw contains a water flow channel whose flow rate and differential temperature are measured to derive a transverse power distribution. Beam centroid position is measured by a four-lobe, magnetic-loop pickup. 5 refs., 6 figs

    Our paper analyzes the relation between social media and political movements in contemporary world. Many authors consider that social media, especially social networking sites such as Facebook and Twitter are responsible for triggering the revolutions in the Arab world. Is the “Arab Spring” the result of modern technologies or its origins are more profound and mundane, deeply rooted in the society? Our response is that social media played an important, but only instrumental role.

    Listening habits are strongly influenced by two opposing aspects, the desire for variety and the demand for uniformity in music. In this work we quantify these two notions in terms of instrumentation and production technologies that are typically involved in crafting popular music. We assign an 'instrumentational complexity value' to each music style. Styles of low instrumentational complexity tend to have generic instrumentations that can also be found in many other styles. Styles of high complexity, on the other hand, are characterized by a large variety of instruments that can only be found in a small number of other styles. To model these results we propose a simple stochastic model that explicitly takes the capabilities of artists into account. We find empirical evidence that individual styles show dramatic changes in their instrumentational complexity over the last fifty years. 'New wave' or 'disco' quickly climbed towards higher complexity in the 70s and fell back to low complexity levels shortly afterwards, whereas styles like 'folk rock' remained at constant high instrumentational complexity levels. We show that changes in the instrumentational complexity of a style are related to its number of sales and to the number of artists contributing to that style. As a style attracts a growing number of artists, its instrumentational variety usually increases. At the same time the instrumentational uniformity of a style decreases, i.e. a unique stylistic and increasingly complex expression pattern emerges. In contrast, album sales of a given style typically increase with decreasing instrumentational complexity. This can be interpreted as music becoming increasingly formulaic in terms of instrumentation once commercial or mainstream success sets in.

    Chapman, John J.

    1997-01-01

    A benchtop virtual instrument simulator for CERES (Clouds and the Earth's Radiant Energy System) has been built at NASA, Langley Research Center in Hampton, VA. The CERES instruments will fly on several earth orbiting platforms notably NASDA's Tropical Rainfall Measurement Mission (TRMM) and NASA's Earth Observing System (EOS) satellites. CERES measures top of the atmosphere radiative fluxes using microprocessor controlled scanning radiometers. The CERES Virtual Instrument Simulator consists of electronic circuitry identical to the flight unit's twin microprocessors and telemetry interface to the supporting spacecraft electronics and two personal computers (PC) connected to the I/O ports that control azimuth and elevation gimbals. Software consists of the unmodified TRW developed Flight Code and Ground Support Software which serves as the instrument monitor and NASA/TRW developed engineering models of the scanners. The CERES Instrument Simulator will serve as a testbed for testing of custom instrument commands intended to solve in-flight anomalies of the instruments which could arise during the CERES mission. One of the supporting computers supports the telemetry display which monitors the simulator microprocessors during the development and testing of custom instrument commands. The CERES engineering development software models have been modified to provide a virtual instrument running on a second supporting computer linked in real time to the instrument flight microprocessor control ports. The CERES Instrument Simulator will be used to verify memory uploads by the CERES Flight Operations TEAM at NASA. Plots of the virtual scanner models match the actual instrument scan plots. A high speed logic analyzer has been used to track the performance of the flight microprocessor. The concept of using an identical but non-flight qualified microprocessor and electronics ensemble linked to a virtual instrument with identical system software affords a relatively inexpensive

    It is shown that the long-range part of interatomic interaction is considerably altered in a strong electromagnetic field. Instead of the van der Waals law the potential asymptote can best be described by a dipole-dipole R -3 law. Impact broadening and the line shift in a strong nonresonant field are calculated. The possibility of bound states of two atoms being formed in a strong light field is discussed

    1999-12-01

    The aim of this thesis was to develop two new infrared astronomical instruments, the University of New South Wales Infrared Fabry-Perot spectrometer (UNSWIRF) and the Infrared Camera of the University of New South Wales (IRC-UNSW), and modify an optics for one existing astronomical instrument, the Automated Patrol Telescope (APT). The optical modification of the APT overcame the problem of a curved focal plane and increased the flat field of view from 0.9° to 5°, twice as big as our original goal. In addition, glass filters of 5-mm thickness can now be inserted into its f/1 beam without image blurring. The simulation, analysis and redesign of the optical system are presented in detail. Several results from testing on the sky are presented as well. UNSWIRF is a near-infrared tunable imaging spectrometer used in conjunction with IRIS on the Anglo-Australian Telescope (AAT). It is the first successful infrared Fabry-Perot spectrometer developed in Australia. Its many challenging features, such as the wide field of view, high spectral and spatial resolution and wide tunable range have been rewarded by exciting observing results obtained during commissioning in February 1996. A major contribution of this thesis has been in the calibration of the Fabry-Perot etalon. IRC-UNSW is a new near-infrared camera with a tunable Fabry-Perot for infrared astronomy. IRC-UNSW is designed for use on the 4-m Anglo-Australian Telescope (AAT) and the 2.3-m telescope of the Australian National University. The camera optics use a novel design of three off-axis mirrors, allowing correction of the off-axis aberrations in the telescopes themselves, and producing images with FWHM blur circles of 10 mm or less over a wide field of view without chromatic affects. An external Fabry- Perot etalon is used as a high-resolution spectrometer. In its opto-mechanical design, the performance of the camera with respect to thermal effects, stray light, misalignment and manufacturing errors have been

  2. Social cognition in schizophrenia.

    Pinkham, Amy E

    2014-01-01

    The topic of social cognition has attracted considerable interest in schizophrenia over the last several years. This construct generally refers to the detection, processing, and utilization of social information and, within the field of schizophrenia, includes several skills such as recognizing emotion, understanding the thoughts and intentions of others, and interpreting social cues. Individuals with schizophrenia show significant impairments in social cognition, and these impairments are strongly related to functional outcome. Treating social cognition yields significant improvements in real-world outcomes, including social functioning and social skill. Importantly, social cognitive abilities are linked to specific neural circuits that have been shown to be abnormal in individuals with schizophrenia. Investigations of these neural networks in patients have also demonstrated that brain activation is significantly correlated with social functioning, which suggests that abnormal activation in social cognitive networks may serve as a mechanism for social dysfunction in schizophrenia. Among the many challenges in this area is the issue of measurement. There is disagreement about which tasks best measure social cognition and many existing measures show poor psychometric properties. A recent project, called the Social Cognition Psychometric Evaluation (SCOPE) study, aims to address these problems by providing the field with a well-validated battery of social cognitive tasks that can be used in treatment outcome trials. Research is honing in on the potential mechanisms of social cognitive impairment in patients, and with improved measurement, there is promise for optimizing behavioral and pharmacologic interventions and remediation strategies. © Copyright 2014 Physicians Postgraduate Press, Inc.

    Pneumatic, hydraulic and allied instrumentation schemes have given way to electronic schemes in recent years thanks to the rapid strides in electronics and allied areas. Principles, design and applications of such state-of-the-art instrumentation schemes form the subject matter of this book. Through representative examples, the basic building blocks of instrumentation schemes are identified and each of these building blocks discussed in terms of its design and interface characteristics. The common generic schemes synthesized with such building blocks are dealt with subsequently. This forms the scope of Part I. The focus in Part II is on application. Displacement and allied instrumentation, force and allied instrumentation and process instrumentation in terms of temperature, flow, pressure level and other common process variables are dealt with separately and exhaustively. Despite the diversity in the sensor principles and characteristics and the variety in the applications and their environments, it is possib...

    To improve the quantitative description of precipitation processes in climate models, the U.S. Department of Energy’s Atmospheric Radiation Measurement (ARM) Climate Research Facility has been collecting observations of the drop size spectra of rain events since early in 2006. Impact disdrometers were the initial choice due to their reliability, ease of maintenance, and relatively low cost. Each of the two units deployed was accompanied by a nearby tipping bucket. In 2010, the tipping buckets were replaced by weighing buckets rain gauges. Five video disdrometers were subsequently purchased and are described in ARM’s VDIS Handbook.1 As of April 2011, three of the weighing bucket instruments were deployed, one was to travel with the second ARM Mobile Facility, and the fifth was a spare. Two of the video disdrometers were deployed, a third was to be deployed later in the spring of 2011, one was to travel with the second ARM Mobile Facility, and the last was a spare. Detailed descriptions of impact disdrometers and their datastreams are provided in this document.

    Terrestrial gamma-ray flashes (TGFs) are brief MeV gamma-ray flashes that are associated with thunderstorms, around 12km in altitude, and are viewed by orbiting satellites. These bright flashes of high energy photons were discovered in 1994. The two major models for TGFs that originate in thunderstorms are the Lightning Leader and Relativistic Feedback Discharge (RFD) model. Both depend on energetic electrons radiating via bremsstrahlung emission. The Lightning Leader model theorizes that lightning step leaders can accelerate electrons to relativistic speeds. The RFD model states that an energetic seed particle can be accelerated to relativistic speeds by strong electric fields inside of a thunderstorm. The main difference in the results of the two models is as follows; the Lightning Leader model results in a wider beam of gamma-rays than the RFD model because the electric field of a thunderstorm is more structured than that of lightning. The TRYAD mission will be the first to fly two detectors, inside CubeSats, in formation to detect TGFs from multiple points in the sky. The data from the CubeSats and the World Wide Lightning Location Network (WWLLN) will likely provide enough insight to constrain or eliminate some of the existing models for TGFs.This summer was spent testing components and constructing the engineering model of the scientific instrument that will be used to detect TGFs. The detector is made up of four lead-doped plastic scintillators which are coupled to arrays of Silicon Photomultipliers (SiPM). The signal from the SiPM array is then fed into a discriminator where a lower energy estimate can be determined and photon counts are recorded. I will present the progress made over the summer constructing the engineering model.

    The Quake-Catcher Network (QCN) involves the community in strong motion data collection by utilizing volunteer computing techniques and low-cost MEMS accelerometers. Volunteer computing provides a mechanism to expand strong-motion seismology with minimal infrastructure costs, while promoting community participation in science. Micro-Electro-Mechanical Systems (MEMS) triaxial accelerometers can be attached to a desktop computer via USB and are internal to many laptops. Preliminary shake table tests show the MEMS accelerometers can record high-quality seismic data with instrument response similar to research-grade strong-motion sensors. QCN began distributing sensors and software to K-12 schools and the general public in April 2008 and has grown to roughly 1500 stations worldwide. We also recently tested whether sensors could be quickly deployed as part of a Rapid Aftershock Mobilization Program (RAMP) following the 2010 M8.8 Maule, Chile earthquake. Volunteers are recruited through media reports, web-based sensor request forms, as well as social networking sites. Using data collected to date, we examine whether a distributed sensing network can provide valuable seismic data for earthquake detection and characterization while promoting community participation in earthquake science. We utilize client-side triggering algorithms to determine when significant ground shaking occurs and this metadata is sent to the main QCN server. On average, trigger metadata are received within 1-10 seconds from the observation of a trigger; the larger data latencies are correlated with greater server-station distances. When triggers are detected, we determine if the triggers correlate to others in the network using spatial and temporal clustering of incoming trigger information. If a minimum number of triggers are detected then a QCN-event is declared and an initial earthquake location and magnitude is estimated. Initial analysis suggests that the estimated locations and magnitudes are

    Hospice and palliative care organizations are expanding their use of standardized instruments and other approaches to measure quality. We undertook a systematic review and evaluation of published patient-level instruments for potential application in hospice and palliative care clinical quality measurement. We searched prior reviews and computerized reference databases from 1990 through February 2007 for studies of instruments relevant to physical, psychological, social, cultural, spiritual, or ethical aspects of palliative care, or measuring prognosis, function or continuity of care. Publications were selected for full review if they provided evidence of psychometric properties or practical application of an instrument tested in or appropriate for a hospice or palliative care population. Selected instruments were evaluated and scored for scientific soundness and potential application in clinical quality measurement. The search found 1427 publications, with 229 selected for full manuscript review. Manuscripts provided information on 129 instruments which were evaluated using a structured scoring guide for psychometric properties. Thirty-nine instruments scoring near or above the 75th percentile were recommended. Most instruments covered multiple domains or focused on care for physical symptoms, psychological or social aspects of care. Few instruments were available to measure cultural aspects of care, structure and process of care, and continuity of care. Numerous patient-level instruments are available to measure physical, psychological and social aspects of palliative care with adequate evidence for scientific soundness and practical clinical use for quality improvement and research. Other aspects of palliative care may benefit from further instrument development research.

    What are the main objectives of social protection institutions in developing countries? What should be their scope and reach? What is the source of their legitimacy? Finding appropriate answers to these questions is essential to understanding, and shaping, the emergence of welfare institutions in low- and middle-income countries. Most available answers rely on instrumental arguments. Few make reference to normative principles. This article draws on three concepts from Rawls – social justice as regulating cooperation, the social minimum, and the need for a freestanding political notion of social justice – to develop a coherent argument for grounding social assistance on social justice. In line with this argument, it identifies some parameters for a justice-based social assistance. This article then discusses, with examples, the tensions existing between a social justice-based social minimum and ‘real’ social assistance institutions emerging in developing countries.

  16. 'Green' preferences as regulatory policy instrument

    International Nuclear Information System (INIS)

    Brennan, Timothy J.

    2006-01-01

    We examine here the suggestion that if consumers in sufficient numbers are willing to pay the premium to have power generated using low-emission technologies, tax or permit policies become less necessary or stringent. While there are implementation difficulties with this proposal, our purpose is more fundamental: Can economics make sense of using preferences as a regulatory instrument? If 'green' preferences are exogenously given, to what extent can or should they be regarded as a substitute for other policies? Even with 'green' preferences, production and consumption of polluting goods continue to impose social costs not borne in the market. Moreover, if green preferences are regarded as a policy instrument, the 'no policy' baseline would require a problematic specification of counterfactual 'non-green' preferences. Viewing green preferences as a regulatory policy instrument is conceptually sensible if the benchmark for optimal emissions is based on value judgments apart from the preferences consumers happen to have. If so, optimal environmental protection would be defined by reference to ethical theory, or, even less favorably, by prescriptions from policy advocates who give their own preferences great weight while giving those of the public at large (and the costs they bear) very little consideration.

    Most existing measures of oral health focus solely on negative oral health, illness, and deficiencies and ignore positive oral health. In an attempt to commence exploration of this challenging field, an innovative instrument was developed, the "Positive Oral Health and Well-Being" (POHW) index. This study aimed to validate this instrument and to explore an initial model of the pathway between oral health attributes and positive oral health. A cross-sectional, multicenter study (Israel, USA, and Germany), was conducted. Our conceptual model suggests that positive oral health attributes, which integrate with positive unawareness or positive awareness on the one hand and with positive perception on the other hand, may result via appropriate oral health behavior on positive oral health. The 17-item self-administered index was built on a theoretical concept by four experts from Israel and Germany. Reliability, factor, and correlation analyses were performed. For external correlations and to measure construct validity of the instrument, we utilized the oral health impact profile-14, self-perceived oral impairment, life satisfaction, self-perceived well-being, sociodemographic and behavioral data, and oral health status indices. Four hundred and seventy participants took part in our three-center study. The combined data set reliability analyses detected two items which were not contributing to the index reliability. Thus, we tested a 15-item construct, and a Cronbach's α value of 0.933 was revealed. Primary factor analysis of the whole sample indicated three subconstructs which could explain 60 % of variance. Correlation analyses demonstrated that the POHW and OHIP-14 were strongly and negatively associated. The POHW correlated strongly and positively with general well-being, moderately with life satisfaction, and weakly with the perceived importance of regular dental checkups. It correlated moderately and negatively with perceived oral impairment, and marginally and

    2016-05-27

    Resilience benefits from the use of protective factors, as opposed to risk factors, which are associated with vulnerability. Considerable research and instrument development has been conducted in clinical settings for patients. The need existed for an instrument to be developed in a workplace setting to measure resilience of employees. This study developed and tested a resilience instrument for employees in the workplace. The research instrument was distributed to executives and nurses working in the United States in hospital settings. Five-hundred-forty completed and usable responses were obtained. The instrument contained an inventory of workplace resilience, a job stress questionnaire, and relevant demographics. The resilience items were written based on previous work by the lead author and inspired by Weick's [1] sense-making theory. A four-factor model yielded an instrument having psychometric properties showing good model fit. Twenty items were retained for the resulting Workplace Resilience Instrument (WRI). Parallel analysis was conducted with successive iterations of exploratory and confirmatory factor analyses. Respondents were classified based on their employment with either a rural or an urban hospital. Executives had significantly higher WRI scores than nurses, controlling for gender. WRI scores were positively and significantly correlated with years of experience and the Brief Job Stress Questionnaire. An instrument to measure individual resilience in the workplace (WRI) was developed. The WRI's four factors identify dimensions of workplace resilience for use in subsequent investigations: Active Problem-Solving, Team Efficacy, Confident Sense-Making, and Bricolage.

  10. Impurity screening in strongly coupled plasma systems

    CERN Document Server

    Kyrkos, S

    2003-01-01

    We present an overview of the problem of screening of an impurity in a strongly coupled one-component plasma within the framework of the linear response (LR) theory. We consider 3D, 2D and quasi-2D layered systems. For a strongly coupled plasma the LR can be determined by way of the known S(k) structure functions. In general, an oscillating screening potential with local overscreening and antiscreening regions emerges. In the case of the bilayer, this phenomenon becomes global, as overscreening develops in the layer of the impurity and antiscreening in the adjacent layer. We comment on the limitations of the LR theory in the strong coupling situation.

    The instrumentation and control system of the high temperature engineering test reactor consists of the instrumentation, control equipments and safety protection systems. There are not many differences in the instrumentation and control equipments design between the HTTR and light water reactors except for some features. Various kinds of R and D of reactor instrumentation were performed taking into account the HTTR operational conditions, and a plant dynamic analysis was carried out considering the operational conditions of the HTTR in order to design the control system. These systems are required to have a high reliability in respect to safety. In the rise-to-power test it was confirmed that the instrumentation has a high reliability and the control system has a high stability and reasonable damped characteristics for various disturbances

    Social communication or pragmatic impairments are characterized and illustrated as involving inappropriate or ineffective use of language and gesture in social contexts. Three clinical vignettes illustrate different pragmatic impairments and the wealth of diagnostic information that can be garnered from observation of a child's social communication behavior. Definitions of, and developmental milestones in, domains of pragmatic competence are provided. Several screening instruments are suggested for use in assessing pragmatic competence within the time-frame of a pediatric examination. Frequent comorbid psychiatric conditions are described and a sample of current neurobiologic research is briefly summarized.

  18. Emerging signs of strong reciprocity in human ontogeny

    Directory of Open Access Journals (Sweden)

    Erin eRobbins

    2011-12-01

    Full Text Available Strong reciprocity is considered here as the propensity to sacrifice resources to be kind or to punish in response to prior acts, a behavior not simply reducible to self-interest and a likely force behind human cooperation and sociality. The aim was to capture emerging signs of strong reciprocity in human ontogeny. Three- and five-year-old middle class American children (N=162 were tested in a simple, multiple round, three-way sharing game involving the child, a generous puppet, and a stingy puppet. At the end of the game, the child was offered an opportunity to sacrifice some of her personal gains to punish one of the puppets. By three years, American children demonstrate a willingness to engage in costly punishment. However, only five-year-olds show some evidence of strong reciprocity by orienting their punishment systematically toward the stingy puppet. Further analyses and 3 additional control conditions demonstrate that such propensity is not simply reducible to a straight imitation, or b inequity aversion. To assess the relative universality of such development, a group of five- to six-year-old children from rural Samoa (N=14 were tested and compared to age and gender matched American children. Samoan children did not manifest the same propensity toward strong reciprocity. The results are interpreted as pointing to 1 the developmental emergence of an ethical stance between three and five years of age, and 2 that the expression of such stance by young children could depend on culture.

  19. Instrumental variables and Mendelian randomization with invalid instruments

    Science.gov (United States)

    Kang, Hyunseung

    Instrumental variables (IV) methods have been widely used to determine the causal effect of a treatment, exposure, policy, or an intervention on an outcome of interest. The IV method relies on having a valid instrument, a variable that is (A1) associated with the exposure, (A2) has no direct effect on the outcome, and (A3) is unrelated to the unmeasured confounders associated with the exposure and the outcome. However, in practice, finding a valid instrument, especially those that satisfy (A2) and (A3), can be challenging. For example, in Mendelian randomization studies where genetic markers are used as instruments, complete knowledge about instruments' validity is equivalent to complete knowledge about the involved genes' functions. The dissertation explores the theory, methods, and application of IV methods when invalid instruments are present. First, when we have multiple candidate instruments, we establish a theoretical bound whereby causal effects are only identified as long as less than 50% of instruments are invalid, without knowing which of the instruments are invalid. We also propose a fast penalized method, called sisVIVE, to estimate the causal effect. We find that sisVIVE outperforms traditional IV methods when invalid instruments are present both in simulation studies as well as in real data analysis. Second, we propose a robust confidence interval under the multiple invalid IV setting. This work is an extension of our work on sisVIVE. However, unlike sisVIVE which is robust to violations of (A2) and (A3), our confidence interval procedure provides honest coverage even if all three assumptions, (A1)-(A3), are violated. Third, we study the single IV setting where the one IV we have may actually be invalid. We propose a nonparametric IV estimation method based on full matching, a technique popular in causal inference for observational data, that leverages observed covariates to make the instrument more valid. We propose an estimator along with

  20. Strong Coupling Corrections in Quantum Thermodynamics

    Perarnau-Llobet, M.; Wilming, H.; Riera, A.; Gallego, R.; Eisert, J.

    2018-03-01

    Quantum systems strongly coupled to many-body systems equilibrate to the reduced state of a global thermal state, deviating from the local thermal state of the system as it occurs in the weak-coupling limit. Taking this insight as a starting point, we study the thermodynamics of systems strongly coupled to thermal baths. First, we provide strong-coupling corrections to the second law applicable to general systems in three of its different readings: As a statement of maximal extractable work, on heat dissipation, and bound to the Carnot efficiency. These corrections become relevant for small quantum systems and vanish in first order in the interaction strength. We then move to the question of power of heat engines, obtaining a bound on the power enhancement due to strong coupling. Our results are exemplified on the paradigmatic non-Markovian quantum Brownian motion.

    Hegelich, B. Manuel; Labun, Lance; Labun, Ou Z.

    2017-06-01

    The long-standing challenge to describing charged particle dynamics in strong classical electromagnetic fields is how to incorporate classical radiation, classical radiation reaction and quantized photon emission into a consistent unified framework. The current, semiclassical methods to describe the dynamics of quantum particles in strong classical fields also provide the theoretical framework for fundamental questions in gravity and hadron-hadron collisions, including Hawking radiation, cosmological particle production and thermalization of particles created in heavy-ion collisions. However, as we show, these methods break down for highly relativistic particles propagating in strong fields. They must therefore be improved and adapted for the description of laser-plasma experiments that typically involve the acceleration of electrons. Theory developed from quantum electrodynamics, together with dedicated experimental efforts, offer the best controllable context to establish a robust, experimentally validated foundation for the fundamental theory of quantum effects in strong classical potentials.

    Pennington, M.R.

    1996-01-01

    This talk gives a brief review of the progress that has been made in calculating the properties of hadrons in strong QCD. In keeping with this meeting I will concentrate on those properties that can be studied with electromagnetic probes. Though perturbative QCD is highly successful, it only applies in a limited kinematic regime, where hard scattering occur, and the quarks move in the interaction region as if they are free, pointlike objects. However, the bulk of strong interactions are governed by the long distance regime, where the strong interaction is strong. It is this regime of length scales of the order of a Fermi, that determines the spectrum of light hadrons and their properties. The calculation of these properties requires an understanding of non-perturbative QCD, of confinement and chiral symmetry breaking. (author)

    The algebraic approach to describing the electroweak and strong interactions is considered within the frames of the binary geometrophysics, based on the principles of the Fokker-Feynman direct interparticle interaction theories of the Kaluza-Klein multidimensional geometrical models and the physical structures theory. It is shown that in this approach the electroweak and strong elementary particles interaction through the intermediate vector bosons, are characterized by the subtypes of the algebraic classification of the complex 3 x 3-matrices [ru

  10. Manipulating light with strongly modulated photonic crystals

    International Nuclear Information System (INIS)

    Notomi, Masaya

    2010-01-01

    Recently, strongly modulated photonic crystals, fabricated by the state-of-the-art semiconductor nanofabrication process, have realized various novel optical properties. This paper describes the way in which they differ from other optical media, and clarifies what they can do. In particular, three important issues are considered: light confinement, frequency dispersion and spatial dispersion. First, I describe the latest status and impact of ultra-strong light confinement in a wavelength-cubic volume achieved in photonic crystals. Second, the extreme reduction in the speed of light is reported, which was achieved as a result of frequency dispersion management. Third, strange negative refraction in photonic crystals is introduced, which results from their unique spatial dispersion, and it is clarified how this leads to perfect imaging. The last two sections are devoted to applications of these novel properties. First, I report the fact that strong light confinement and huge light-matter interaction enhancement make strongly modulated photonic crystals promising for on-chip all-optical processing, and present several examples including all-optical switches/memories and optical logics. As a second application, it is shown that the strong light confinement and slow light in strongly modulated photonic crystals enable the adiabatic tuning of light, which leads to various novel ways of controlling light, such as adiabatic frequency conversion, efficient optomechanics systems, photon memories and photons pinning.

    This study compared the torsional resistance of two brands of rotary nickel-titanium (NiTi) instruments indicated for endodontic retreatment. Mtwo retreatment instruments #15 and #25 (VDW, Munich, Germany) and ProTaper Universal retreatment instruments D2 and D3 (Maillefer/Dentsply, Ballaigues, Switzerland) were subjected to a torsional assay in clockwise rotation. The two parameters evaluated were maximum torque and angular deflection at failure. Fractured instruments had their fractured surfaces and helical shafts examined by scanning electron microscopy. The results indicated that the angular deflection at fracture decreased in the following order: Mtwo retreatment file #15 > Mtwo retreatment file #25 > ProTaper Universal retreatment file D2 > ProTaper Universal retreatment file D3. As for the maximum torque values, the results revealed the following descending order: ProTaper Universal file D2 > Mtwo retreatment file #25 > ProTaper Universal file D3 > Mtwo retreatment file #15. Scanning electron microscopic analysis revealed that plastic deformation occurred along the helical shaft of the fractured instruments. Fractured surfaces were of the ductile type. The instruments tested showed different torsional behavior depending on the parameter evaluated. If one considers that high angular deflection values may serve as a safety factor, then the Mtwo retreatment instruments showed significantly better results.

The next generation of elementary particle physics experiments would depend vitally on new ideas in instrumentation. This is a field where creativity and imagination play a major role and large budgets are not a prerequisite. One of the unique features was the presentation of four laboratory experiments using modern techniques and instrumentation. Refs, figs and tabs

    A blank extender module used to mount an instrument module in front of its console for repair or test purposes has been equipped with a rotatable mount and means for locking the mount at various angles of rotation for easy accessibility. The rotatable mount includes a horizontal conduit supported by bearings within the blank module. The conduit is spring-biased in a retracted position within the blank module and in this position a small gear mounted on the conduit periphery is locked by a fixed pawl. The conduit and instrument mount can be pulled into an extended position with the gear clearing the pawl to permit rotation and adjustment of the instrument

    Some classical old fashioned instruments (such as the Wood-Anderson seismometers), as well as some modern instruments (like the all-quartz made Verbaandert-Melchior tiltmeters), conventionally require an impractical recording system obtained by a photographic drum recorder in a darkroom. Simple electronic equipment (made by readily available, low cost electronics) may help in using such kind of instruments allowing a useful digital recording. This will reduce the time-hour in data acquisition and storage (and the manual error) and will increase the accuracy. The theory of operations and some results obtained using the described equipment are shown.

  20. The extended reciprocity: Strong belief outperforms persistence.

    2017-05-21

    The existence of cooperation is a mysterious phenomenon and demands explanation, and direct reciprocity is one key potential explanation for the evolution of cooperation. Direct reciprocity allows cooperation to evolve for cooperators who switch their behavior on the basis of information about the opponent's behavior. Here, relevant to direct reciprocity is information deficiency. When the opponent's last move is unknown, how should players behave? One possibility is to choose cooperation with some default probability without using any further information. In fact, our previous paper (Kurokawa, 2016a) examined this strategy. However, there might be beneficial information other than the opponent's last move. A subsequent study of ours (Kurokawa, 2017) examined the strategy which uses the own last move when the opponent's last move is unknown, and revealed that referring to the own move and trying to imitate it when information is absent is beneficial. Is there any other beneficial information else? How about strong belief (i.e., have infinite memory and believe that the opponent's behavior is unchanged)? Here, we examine the evolution of strategies with strong belief. Analyzing the repeated prisoner's dilemma game and using evolutionarily stable strategy (ESS) analysis against an invasion by unconditional defectors, we find the strategy with strong belief is more likely to evolve than the strategy which does not use information other than the opponent player's last move and more likely to evolve than the strategy which uses not only the opponent player's last move but also the own last move. Strong belief produces the extended reciprocity and facilitates the evolution of cooperation. Additionally, we consider the two strategies game between strategies with strong belief and any strategy, and we consider the four strategies game in which unconditional cooperators, unconditional defectors, pessimistic reciprocators with strong belief, and optimistic reciprocators with

  1. Milieu Models and Milieu Instruments in Market Research

    Directory of Open Access Journals (Sweden)

    Rainer Diaz-Bone

    2004-05-01

    Full Text Available In the case of social milieu research, the practical, non-scientific context of market research can create problems for practical social research. Some of these problems are examined in this paper. Social milieu research can be seen as a new approach to social structure. It can also be seen as a paradigm for the combination of quantitative and qualitative research techniques and research strategies. Two important and influential milieu models are presented here: the milieu model of Gerhard SCHULZE and the milieu model of Sinus Sociovision. In this paper two important concepts are differentiated: the milieu model and the milieu instrument. The milieu model (the "milieu map" represents the social structure of a society as an organized set of social milieus. The milieu instrument consists of quantitative and qualitative techniques for measuring and interpreting the social milieus of the milieu model. In the context of market research, the milieu instrument enables the milieu-researcher to relate the customer's product to the social milieus in an interpretative and also quantifying way. However, there are two main problems: 1. Social milieu research in the context of market research is theoretically and methodologically highly sophisticated. Therefore the acceptance of milieu-thinking and milieu-theorizing must be created and distributed in the field of market research, namely to the customer of commercial milieu research. The distribution of milieu-theory has to be realized through the whole process of consulting and the customer has to be integrated in the process of qualitative interpretation. 2. In using the concept of social field of Pierre BOURDIEU, a problematic strategy of market research companies is analyzed. On one hand, market research companies are interested in distributing the knowledge and in maximizing the acceptance of their milieu-model in the field of market research, so that it becomes a prevailing standard, a "currency" in the

  2. Synthetic social support: Theorizing lay health worker interventions.

    Levels of social support are strongly associated with health outcomes and inequalities. The use of lay health workers (LHWs) has been suggested by policy makers across the world as an intervention to identify risks to health and to promote health, particularly in disadvantaged communities. However, there have been few attempts to theorize the work undertaken by LHWs to understand how interventions work. In this article, the authors present the concept of 'synthetic socialsupport' and distinguish it from the work of health professionals or the spontaneous social support received from friends and family. The authors provide new empirical data to illustrate the concept based on qualitative, observational research, using a novel shadowing method involving clinical and non-clinical researchers, on the everyday work of 'pregnancy outreach workers' (POWs) in Birmingham, UK. The service was being evaluated as part of a randomized controlled trial. These LHWs provided instrumental, informational, emotional and appraisal support to the women they worked with, which are all key components of social support. The social support was 'synthetic' because it was distinct from the support embedded in spontaneous social networks: it was non-reciprocal; it was offered on a strictly time-limited basis; the LHWs were accountable for the relationship, and the social networks produced were targeted rather than spontaneous. The latter two qualities of this synthetic form of social support may have benefits over spontaneous networks by improving the opportunities for the cultivation of new relationships (both strong and weak ties) outside the women's existing spontaneous networks that can have a positive impact on them and by offering a reliable source of health information and support in a chaotic environment. The concept of SSS can help inform policy makers about how deploying lay workers may enable them to achieve desired outcomes, specify their programme theories and evaluate

    2011-01-01

    With the advent of microprocessors and digital-processing technologies as catalyst, classical sensors capable of simple signal conditioning operations have evolved rapidly to take on higher and more specialized functions including validation, compensation, and classification. This new category of sensor expands the scope of incorporating intelligence into instrumentation systems, yet with such rapid changes, there has developed no universal standard for design, definition, or requirement with which to unify intelligent instrumentation. Explaining the underlying design methodologies of intelligent instrumentation, Intelligent Instrumentation: Principles and Applications provides a comprehensive and authoritative resource on the scientific foundations from which to coordinate and advance the field. Employing a textbook-like language, this book translates methodologies to more than 80 numerical examples, and provides applications in 14 case studies for a complete and working understanding of the material.

    To describe and validate a new scale, Gain in Alzheimer care Instrument (GAIN), and to measure gains in dementia caregiving. Items in GAIN were derived through a qualitative study of family carers of persons with dementia (PWD). Content validity of GAIN was established by a team of dementia care experts (geriatrician, nurse, and social worker) and through focus group discussion with 15 family carers. Consecutive carers of PWD were administered a questionnaire containing GAIN and other measures. Ambulatory dementia clinic of a tertiary hospital and the local Alzheimer's Association. Family carers of PWD. The psychometric properties of GAIN were examined, in particular, exploratory factor analysis and construct validity through correlation with extant measures; Positive Aspects of Caregiving (PAC), Dementia Management Strategies Scale (DMSS), and Zarit Burden Interview (ZBI). Two hundred thirty-eight English-speaking carers completed the survey. Mean age of carers was 50.1 year (standard deviation [SD] 10.1) and females (68.1%) and child carers (81.3%) comprised the majority. Mean GAIN score was 30.5 (SD 6.5). Internal consistency of GAIN by Cronbach's alpha was 0.89 and test-retest reliability (2 weeks) by Intraclass Correlation Coefficient was 0.70. GAIN correlated strongly with PAC (r = 0.68, df = 236, p 1 at 5.28, accounting for 52.8% of the variance. GAIN is a psychometrically reliable and valid instrument for measuring gains in dementia caregiving. It adds an important dimension to carer assessment in dementia.

    2004-08-01

    Successful description of robust collective flow phenomena at RHIC by ideal hydrodynamics, recent observations of bound c-barc,q-barq states on the lattice, and other theoretical developments indicate that QGP produced at RHIC, and probably in a wider temperature region T{sub c} < T < 4T{sub c}, is not a weakly coupled quasiparticle gas as believed previously. We discuss how strong the interaction is and why it seems to generate hundreds of binary channels with bound states, surviving well inside the QGP phase. We in particular discuss their effect on pressure and viscosity. We conclude by reviewing the similar phenomena for other 'strongly coupled systems', such as (i) strongly coupled supersymmetric theories studied via Maldacena duality; (ii) trapped ultra-cold atoms with very large scattering length, tuned to Feschbach resonances.

  14. Strong Coupling between Plasmons and Organic Semiconductors

    2014-05-01

    Full Text Available In this paper we describe the properties of organic material in strong coupling with plasmon, mainly based on our work in this field of research. The strong coupling modifies the optical transitions of the structure, and occurs when the interaction between molecules and plasmon prevails on the damping of the system. We describe the dispersion relation of different plasmonic systems, delocalized and localized plasmon, coupled to aggregated dyes and the typical properties of these systems in strong coupling. The modification of the dye emission is also studied. In the second part, the effect of the microscopic structure of the organics, which can be seen as a disordered film, is described. As the different molecules couple to the same plasmon mode, an extended coherent state on several microns is observed.

  15. A theory of the strong interactions

    International Nuclear Information System (INIS)

    Gross, D.J.

    1979-01-01

    The most promising candidate for a fundamental microscopic theory of the strong interactions is a gauge theory of colored quarks-Quantum Chromodynamics (QCD). There are many excellent reasons for believing in this theory. It embodies the broken symmetries, SU(3) and chiral SU(3)xSU(3), of the strong interactions and reflects the success of (albeit crude) quark models in explaining the spectrum of the observed hadrons. The hidden quantum number of color, necessary to account for the quantum numbers of the low lying hadrons, plays a fundamental role in this theory as the SU(3) color gauge vector 'gluons' are the mediators of the strong interactions. The absence of physical quark states can be 'explained' by the hypothesis of color confinement i.e. that hadrons are permanently bound in color singlet bound states. Finally this theory is unique in being asymptotically free, thus accounting for the almost free field theory behvior of quarks observed at short distances. (Auth.)

    2007-01-01

    We propose a number of new investigations on aspects of radiation from high energy electron and positron beams (10-300 GeV) in single crystals and amorphous targets. The common heading is radiation emission by electrons and positrons in strong electromagnetic fields, but as the setup is quite versatile, other related phenomena in radiation emission can be studied as well. The intent is to clarify the role of a number of important aspects of radiation in strong fields as e.g. observed in crystals. We propose to measure trident 'Klein-like' production in strong crystalline fields, 'crystalline undulator' radiation, 'sandwich' target phenomena, LPM suppression of pair production as well as axial and planar effects in contributions of spin to the radiation.

    2016-11-23

    Even though the Standard Model (SM) is weakly coupled at the Fermi scale, a new strong dynamics involving its degrees of freedom may conceivably lurk at slightly higher energies, in the multi TeV range. Approximate symmetries provide a structurally robust context where, within the low energy description, the dimensionless SM couplings are weak, while the new strong dynamics manifests itself exclusively through higher-derivative interactions. We present an exhaustive classification of such scenarios in the form of effective field theories, paying special attention to new classes of models where the strong dynamics involves, along with the Higgs boson, the SM gauge bosons and/or the fermions. The IR softness of the new dynamics suppresses its effects at LEP energies, but deviations are in principle detectable at the LHC, even at energies below the threshold for production of new states. Our construction provides the so far unique structurally robust context where to motivate several searches in Higgs physics, d...

    Electronic structure and physical properties of strongly correlated materials containing elements with partially filled 3d, 4d, 4f and 5f electronic shells is analyzed by Dynamical Mean-Field Theory (DMFT). DMFT is the most universal and effective tool used for the theoretical investigation of electronic states with strong correlation effects. In the present book the basics of the method are given and its application to various material classes is shown. The book is aimed at a broad readership: theoretical physicists and experimentalists studying strongly correlated systems. It also serves as a handbook for students and all those who want to be acquainted with fast developing filed of condensed matter physics.

    2018-04-01

    Receiver aperture averaging technique is employed in underwater wireless optical communication (UWOC) systems to mitigate the effects of oceanic turbulence, thus to improve the system performance. The irradiance flux variance is a measure of the intensity fluctuations on a lens of the receiver aperture. Using the modified Rytov theory which uses the small-scale and large-scale spatial filters, and our previously presented expression that shows the atmospheric structure constant in terms of oceanic turbulence parameters, we evaluate the irradiance flux variance and the aperture averaging factor of a spherical wave in strong oceanic turbulence. Irradiance flux variance variations are examined versus the oceanic turbulence parameters and the receiver aperture diameter are examined in strong oceanic turbulence. Also, the effect of the receiver aperture diameter on the aperture averaging factor is presented in strong oceanic turbulence.

    Full Text Available This article aims to identify if the participation of young people from the popular strata in projects of art and social education of a Third Sector organization in their leisure time, influenced them to appropriation’ art, even as a form of leisure. For that, a qualitative research was adopted as methodology, with bibliographic-documentary and field approaches. With the data analysis, it was noticed that such initiatives exert a strong influence on the appropriation of the art by the studied subjects. However, the desires of these young people in art are diversified, and can be understood as work, as leisure or as an instrument of social transformation. One of the perceived difficulties was the maintenance of the space still primarily linked to public funding.

    The Sulfur Dioxide Analyzer measures sulfur dioxide based on absorbance of UV light at one wavelength by SO2 molecules which then decay to a lower energy state by emitting UV light at a longer wavelength. Specifically, SO2 + hυ1 →SO2 *→SO2 + hυ2 The emitted light is proportional to the concentration of SO2 in the optical cell. External communication with the analyzer is available through an Ethernet port configured through the instrument network of the AOS systems. The Model 43i-TLE is part of the i-series of Thermo Scientific instruments. The i-series instruments are designed to interface with external computers through the proprietary Thermo Scientific iPort Software. However, this software is somewhat cumbersome and inflexible. Brookhaven National Laboratory (BNL) has written an interface program in National Instruments LabView that both controls the Model 43i-TLE Analyzer AND queries the unit for all measurement and housekeeping data. The LabView vi (the software program written by BNL) ingests all raw data from the instrument and outputs raw data files in a uniform data format similar to other instruments in the AOS and described more fully in Section 6.0 below.

    In the steel industry, though the investment in isotope-equipped measuring instruments is small as compared with that in machinery, they play important role in the moisture measurement in sintering and blast furnaces, the thickness measurement in rolling process and others in automatic control systems. The economic aspect of the isotope-equipped measuring instruments is described on the basis of the practices in Kimitsu Works of Nippon Steel Corporation: distribution of such instruments, evaluation of economic effects, usefulness evaluation in view of raising the accuracy, and usefulness evaluation viewed from the failure of the isotope instruments. The evaluation of economic effects was made under the premise that the isotope-equipped measuring instruments are not employed. Then, the effects of raising the accuracy are evaluated for a γ-ray plate thickness gauge and a neutron moisture gauge for coke in a blast furnace. Finally, the usefulness was evaluated, assuming possible failure of the isotope-equipped measuring instruments. (J.P.N.)

    We show by experiment that an electron impinging on an electric field that is of critical magnitude in its rest frame, may produce an electron-positron pair. Our measurements address higher-order QED, using the strong electric fields obtainable along particular crystallographic directions in single crystals. For the amorphous material our data are in good agreement with theory, whereas a discrepancy with theory on the magnitude of the trident enhancement is found in the precisely aligned case where the strong electric field acts.

  11. Gluon scattering amplitudes at strong coupling

    We describe how to compute planar gluon scattering amplitudes at strong coupling in N = 4 super Yang Mills by using the gauge/string duality. The computation boils down to finding a certain classical string configuration whose boundary conditions are determined by the gluon momenta. The results are infrared divergent. We introduce the gravity version of dimensional regularization to define finite quantities. The leading and subleading IR divergencies are characterized by two functions of the coupling that we compute at strong coupling. We compute also the full finite form for the four point amplitude and we find agreement with a recent ansatz by Bern, Dixon and Smirnov.

    1979-01-01

    Full Text Available Certain classes of analytic functions in tube domains TC=ℝn+iC in n-dimensional complex space, where C is an open connected cone in ℝn, are studied. We show that the functions have a boundedness property in the strong topology of the space of tempered distributions g′. We further give a direct proof that each analytic function attains the Fourier transform of its spectral function as distributional boundary value in the strong (and weak topology of g′.

  13. Including virtual photons in strong interactions

    In the perturbative field-theoretical models we investigate the inclusion of the electromagnetic interactions into the purely strong theory that describes hadronic processes. In particular, we study the convention for splitting electromagnetic and strong interactions and the ambiguity of such a splitting. The issue of the interpretation of the parameters of the low-energy effective field theory in the presence of electromagnetic interactions is addressed, as well as the scale and gauge dependence of the effective theory couplings. We hope, that the results of these studies are relevant for the electromagnetic sector of ChPT. (orig.)

  14. Thermodynamical instabilities under strong magnetic fields

    Chen, Y. J.

    2017-03-01

    The thermodynamical instabilities of low densities in the n p matter and n p e matter are studied within several relativistic nuclear models under some values of magnetic fields. The results are compared between each other and the effects of the symmetry energy slope at saturation density on the instability are investigated. The instability regions can exhibit bands due to the presence of Landau levels for very strong magnetic fields of the order of 1017 G, while for weaker magnetic fields, the bands are replaced by many diffused or scattered pieces. It also shows that the proton fraction in the inner crust of neutron stars may be complex under strong magnetic fields.

    This review discusses the construction of a theory and the analysis of phenomena occurring in strongly correlated Fermi systems such as high-T{sub c} superconductors, heavy-fermion metals, and quasi-two-dimensional Fermi systems. It is shown that the basic properties and the universal behavior of strongly correlated Fermi systems can be described in the framework of the Fermi-condensate quantum phase transition and the well-known Landau paradigm of quasiparticles and the order parameter. The concept of fermion condensation may be fruitful in studying neutron stars, finite Fermi systems, ultra-cold gases in traps, and quark plasma. (reviews of topical problems)

    In this paper, a new perturbation technique is employed to solve strongly nonlinear Duffing oscillators, in which a new parameter α=α(ε)α=α(ε) is defined such that the value of α is always small regardless of the magnitude of the original parameter εε. Therefore, the strongly nonlinear Duffing oscillators with large parameter ε are transformed into a small parameter system with respect to αα. Approximate solution obtained by the present method is compared with the solution of energy balance m...

    We use holographic correspondence to argue that Euclidean (Bunch-Davies) vacuum is a late-time attractor of the dynamical evolution of quantum gauge theories at strong coupling. The Bunch-Davies vacuum is not an adiabatic state, if the gauge theory is non-conformal — the comoving entropy production rate is nonzero. Using the N=2{sup ∗} gauge theory holography, we explore prospects of explaining current accelerated expansion of the Universe as due to the vacuum energy of a strongly coupled QFT.

  9. Reducing Weak to Strong Bisimilarity in CCP

    Directory of Open Access Journals (Sweden)

    Andrés Aristizábal

    2012-12-01

    Full Text Available Concurrent constraint programming (ccp is a well-established model for concurrency that singles out the fundamental aspects of asynchronous systems whose agents (or processes evolve by posting and querying (partial information in a global medium. Bisimilarity is a standard behavioural equivalence in concurrency theory. However, only recently a well-behaved notion of bisimilarity for ccp, and a ccp partition refinement algorithm for deciding the strong version of this equivalence have been proposed. Weak bisimiliarity is a central behavioural equivalence in process calculi and it is obtained from the strong case by taking into account only the actions that are observable in the system. Typically, the standard partition refinement can also be used for deciding weak bisimilarity simply by using Milner's reduction from weak to strong bisimilarity; a technique referred to as saturation. In this paper we demonstrate that, because of its involved labeled transitions, the above-mentioned saturation technique does not work for ccp. We give an alternative reduction from weak ccp bisimilarity to the strong one that allows us to use the ccp partition refinement algorithm for deciding this equivalence.

  10. Strong motion duration and earthquake magnitude relationships

    International Nuclear Information System (INIS)

    Salmon, M.W.; Short, S.A.; Kennedy, R.P.

    1992-06-01

    Earthquake duration is the total time of ground shaking from the arrival of seismic waves until the return to ambient conditions. Much of this time is at relatively low shaking levels which have little effect on seismic structural response and on earthquake damage potential. As a result, a parameter termed ''strong motion duration'' has been defined by a number of investigators to be used for the purpose of evaluating seismic response and assessing the potential for structural damage due to earthquakes. This report presents methods for determining strong motion duration and a time history envelope function appropriate for various evaluation purposes, for earthquake magnitude and distance, and for site soil properties. There are numerous definitions of strong motion duration. For most of these definitions, empirical studies have been completed which relate duration to earthquake magnitude and distance and to site soil properties. Each of these definitions recognizes that only the portion of an earthquake record which has sufficiently high acceleration amplitude, energy content, or some other parameters significantly affects seismic response. Studies have been performed which indicate that the portion of an earthquake record in which the power (average rate of energy input) is maximum correlates most closely with potential damage to stiff nuclear power plant structures. Hence, this report will concentrate on energy based strong motion duration definitions
