Inheritance of the Ityr or the Itys allele of the Ity murine gene confers resistance or increased susceptibility, respectively, to Salmonella typhimurium infection. Recent studies have documented that Ity gene expression may determine net intracellular replication of S. typhimurium by modulating macrophage function. The purpose of this study was to determine if Ity gene expression modulated macrophage stem cell proliferation as well. To detect possible Ity-associated alterations in macrophage stem cell proliferation during endotoxin challenge or S. typhimurium infection, the congenic strain pair BALB/c (Itys) and C.D2-Idh-1, Pep-3 N20F8 (Ityr) were injected intraperitoneally with 25 micrograms of bacterial lipopolysaccharide (LPS) or approximately 10(3) S. typhimurium, and myelopoiesis was evaluated. At 72 h after LPS injection, both BALB/c and C.D2 mice developed comparable degrees of bone marrow hypocellularity and splenomegaly, and cell sizing profiles indicated a normal response to a single injection of LPS in both strains of mice. Although an inhibitor to colony-stimulating factor activity was detected in the sera and plasma of C.D2 mice, the number of myeloid stem cells cultured from the bone marrow and spleen of each mouse strain were comparable. S. typhimurium infection resulted in earlier symptoms, a larger bacterial load, a higher mortality rate, and a greater bone marrow hypocellularity and splenomegaly in BALB/c mice compared with those in C.D2 mice. Despite a dramatic increase in bacterial load, a decrease in both bone marrow and splenic myeloid stem cell numbers was noted in BALB/c mice, while stem cell numbers remained constant in C.D2 mice between days 3 and 5 and increased dramatically at day 7 after infection. These data suggest that BALB/c and C.D2 mice may exhibit a divergent myelopoietic response to S. typhimurium infection. It appears that a paradoxical failure of myelopoiesis in Itys mice during S. typhimurium infection may contribute to the

Author Disambiguation in PubMed: Evidence on the Precision and Recall of Author-ity among NIH-Funded Scientists.

We examined the usefulness (precision) and completeness (recall) of the Author-ity author disambiguation for PubMed articles by associating articles with scientists funded by the National Institutes of Health (NIH). In doing so, we exploited established unique identifiers-Principal Investigator (PI) IDs-that the NIH assigns to funded scientists. Analyzing a set of 36,987 NIH scientists who received their first R01 grant between 1985 and 2009, we identified 355,921 articles appearing in PubMed that would allow us to evaluate the precision and recall of the Author-ity disambiguation. We found that Author-ity identified the NIH scientists with 99.51% precision across the articles. It had a corresponding recall of 99.64%. Precision and recall, moreover, appeared stable across common and uncommon last names, across ethnic backgrounds, and across levels of scientist productivity.

Social Responsibility and Healthcare in Finland.

Science.gov (United States)

Ahola-Launonen, Johanna

2016-07-01

This article examines current trends and prospects in Finnish healthcare literature and discussion. The Finnish healthcare system was long considered to manifest an equal, universal, and solidaristic welfare scheme. However, recent data reveals structural inequalities in access to healthcare that result in health differences among socioeconomic groups. The political will aims at tackling these inequalities, but the ideological trend toward responsibilization of the individual taking place across political spheres elsewhere in Europe creates potential challenges to this goal. The applications of this trend have a theoretical background in the responsibility-sensitive egalitarian-or luck egalitarian-tradition. The theory, which is unfit for real-life policy applications, has explicit appeal in considerations aiming at the responsibilization of the individual within the healthcare sector. It remains to be seen in which direction the Finnish welfare schemes will continue to develop.

A Short Tale of the Black Sheep of -ITY

2013-01-01

Once upon a time, computer engineers of the ancient world used the abbreviation of “-ITY” ([eye-tee]) as a shorthand for “Information TechnologY”. It was an appropriate abbreviation as it reminded everyone of the core purposes and aspects of information technology, which made not only the computer engineers, but also their clients, happy.   Whenever the engineers were programming a software application or setting up a computing service to cover the needs of their clients, they stuck to the four paradigms of -ITY: * “Functional-ITY”, i.e. ensuring that a service or application has a purpose and a justification of being; * “Avalabil-ITY”, i.e. ensuring that this service or application is functional whenever a client wants to use it; * “Usabil-ITY”, i.e. ensuring that this client does not get fed up by a badly designed user interface or disappointed by the service’s or application&am...

The Effects of RF Sputtering Power and Gas Pressure on Structural and Electrical Properties of ITiO Thin Film

2012-01-01

Full Text Available Transparent conductive titanium-doped indium oxide (ITiO films were deposited on corning glass substrates by RF magnetron sputtering method. The effects of RF sputtering power and Ar gas pressure on the structural and electrical properties of the films were investigated experimentally, using a 2.5 wt% TiO2-doped In2O3 target. The deposition rate was in the range of around 20~60 nm/min under the experimental conditions of 5~20 mTorr of gas pressure and 220~350 W of RF power. The lowest volume resistivity of 1.2×10−4  Ω-cm and the average optical transmittance of 75% were obtained for the ITiO film, prepared at RF power of 300 W and Ar gas pressure of 15 mTorr. This volume resistivity of 1.2×10−4  Ω-cm is low enough as a transparent conducting layer in various electrooptical devices, and it is comparable with that of ITO or ZnO:Al conducting layer.

In order to achieve esthetically more satisfying results, it has been proposed to place ITI implants with their border between the rough and smooth surfaces below the level of the alveolar crest, thereby obtaining a submucosally located implant shoulder following healing. The aim of the present experimental study was to clinically and radiographically evaluate the tissue response to the placement of one-stage transmucosal implants with the border between the rough and the smooth surfaces sunk by 1 mm into a subcrestal location. 11 patients underwent comprehensive dental care including the placement of 2 implants of the ITI Dental Implant System in the same quadrant (test and control). Randomly assigned control implants were placed according to the manufacturer's instructions, i.e. the border between the rough titanium plasma-sprayed and the smooth polished surfaces precisely at the alveolar crest. At the test implant the apical border of the polished surface was placed approximately 1 mm below the alveolar crest. Probing bone levels were assessed at implant placement (baseline), 4 and 12 months later. Modified plaque and modified gingival indices were recorded at 1, 2, 3, 4 and 12 months. Clinical probing depth and "attachment" levels were measured at 4 and 12 months. All parameters were assessed at 6 sites around each implant. The mean for each implant was calculated and used for analysis. The Wilcoxon matched pairs signed rank test and the Student t-test were applied to detect differences over time and between the test and control implants. At baseline, a mean difference in probing bone level of -0.86 mm (SD 0.43 mm, p placed more deeply. Both test and control implants lost a significant amount of clinical bone height during the first 4 months (test 1.16 mm, p placed under standard conditions, the bone adjacent to the polished surface of more deeply placed ITI implants is also lost over time. From a biological point of view, the placement of the border between

2016-05-01

Full Text Available In the case of this economic operator, manufacturing or trading textile products, the corporate social responsibility is a social must, and it consists of a set of objectives which must be implemented by the management of the economic operator in all departments. In order to understand the implications of a social responsibile management in the textile products domain, it is required to analise the juridical framework. Interesting is the choice in this area of the production and the marketing of textile products, to only adopt/use one regulation, not a directive or a legislative package consisting in a directive and a regulation. As a result of legal analysis performed, we support the maintenance of the use, as a legal instrument, of the European regulation type normative document, but we suggest the extension of the provisions of the European normative act and its transformation into a particular complex normative act, beyond the scope of the aspects concerning the labelling.

Full Text Available We are pleased to present this AJIS Special issue on Green IT/IS (Sustainable Computing. There are five papers published in this special issue of the AJIS which reflect the diversity of this emerging and important area of research in Information Systems. Environmental sustainability is one of if not the most important challenge facing organisations and society in the 21st century. Information systems and information technology have a major role to play in both reducing its environmental impact and providing the systems and technological innovation to reduce the environmental impact of organisations. Currently there is a lack of rigorous empirical studies which are theory and evidence based to provide a sound basis for understanding IT green best practices and how these can be best adopted in organisations. This special issue of the AJIS contributes this current gap in the knowledge concerning green IS and IT with five empirical research papers which examined five different aspects of green IS and IT.

Miele, Renato; Gunasekaran, Angappa; Yusuf, Yahaya Y.

2000-10-01

The change in IT/IS strategy is about the Internet becoming a major part of the corporate environment and driving decisions more and more. Companies of all sizes and industries can fully engage employees, customers and partners to capitalize upon the new Internet economy. They can optimize supply chains, managing strategic relationships, reducing time to market, sharing vital information, and increasing productivity and shareholder value. Remaining competitive in today's rapidly changing global marketplace requires fast action. The problem is now how much, how soon, and what kind of Internet based components are essential for companies to be successful, and how the adoption of E-Integration can become a critical component of company's survival in an increasingly competitive environment. How information, knowledge and innovation processes can drive business success are fundamental notions for the information- based economy, which have been extensively researched and confirmed throughout the IT revolution. The new capabilities to use the Internet to supply large amounts of relevant information from multiple internal and external sources give the possibility to move from isolate Information Systems toward an integrated environment in every business organization. The article addresses how E-Integration must link together data from multiple sources, providing a seamless system, fully interoperable with pre-existing IT environment, totally scalable and upgradeable.

Choosing health, constrained choices.

Science.gov (United States)

Chee Khoon Chan

2009-12-01

In parallel with the neo-liberal retrenchment of the welfarist state, an increasing emphasis on the responsibility of individuals in managing their own affairs and their well-being has been evident. In the health arena for instance, this was a major theme permeating the UK government's White Paper Choosing Health: Making Healthy Choices Easier (2004), which appealed to an ethos of autonomy and self-actualization through activity and consumption which merited esteem. As a counterpoint to this growing trend of informed responsibilization, constrained choices (constrained agency) provides a useful framework for a judicious balance and sense of proportion between an individual behavioural focus and a focus on societal, systemic, and structural determinants of health and well-being. Constrained choices is also a conceptual bridge between responsibilization and population health which could be further developed within an integrative biosocial perspective one might refer to as the social ecology of health and disease.

Florkowska, Lucyna; Bryt-Nitarska, Izabela

2018-04-01

The notion of Integrated Territorial Investments (ITI) appears more and more frequently in contemporary regional development strategies. Formulating the main assumptions of ITI is a response to a growing need for a co-ordinated, multi-dimensional regional development suitable for the characteristics of a given area. Activities are mainly aimed at improving people's quality of life with their significant participation. These activities include implementing the Sustainable development Goals (SDGs). Territorial investments include, among others, projects in areas where land and building use is governed not only by general regulations (Spatial Planning and Land Development Act) but also by separate legal acts. This issue also concerns areas with active mines and post-mining areas undergoing revitalization. For the areas specified above land development and in particular making building investments is subject to the requirements set forth in the Geological and Mining Law and in the general regulations. In practice this means that factors connected with the present and future mining impacts must be taken into consideration in planning the investment process. This article discusses the role of proper assessment of local geological conditions as well as the current and future mining situation in the context of proper planning and performance of the Integrated Territorial Investment programme and also in the context of implementing the SDGs. It also describes the technical and legislative factors which need to be taken into consideration in areas where mining is planned or where it took place in the past.

Mental health effects from radiological accidents and their social management

Brenot, J.; Charron, S.; Verger, P.

2000-01-01

Mental health effects resulting from exposure to radiation have been identified principally in the context of large radiological accidents. They cover an extended scope of manifestations in relation with the notion of stress: increase of some hormones, modifications in mental concentration, symptoms of anxiety and depression, psycho-somatic diseases, deviation behaviours, and, on the long term, a possible post-traumatic stress disorder (PTSD). The main results come from the Three Mile Island, Goiania, and Chernobyl accidents and several modifying factors have been identified. Considering those facts, diverse social responses can be brought to reduce the detriment to affected individuals and communities. Medical treatments are necessary for persons who suffer from pathological diseases. In most cases, a structured public health follow-up is required to establish the seriousness of the health problems, to forecast the extent of medical and psychological assistance, and to inform people who express fears and worries. Social assistance is always valuable under various forms: financial compensations, preferential medical care, and particular advantages concerning working and living conditions. If this social assistance is necessary and helpful, it also induces a loss in personal adjustment capability and initiative capacity. To overcome those negative impacts, some guidelines to authorities' action can be set up. But the best approach, not excluding the previous ones, remains problem solving at the local level through community responsibilization; some instructive examples come from the Chernobyl experience.

Understanding Social Media Logic

José van Dijck

2013-08-01

Full Text Available Over the past decade, social media platforms have penetrated deeply into the mech­anics of everyday life, affecting people's informal interactions, as well as institutional structures and professional routines. Far from being neutral platforms for everyone, social media have changed the conditions and rules of social interaction. In this article, we examine the intricate dynamic between social media platforms, mass media, users, and social institutions by calling attention to social media logic—the norms, strategies, mechanisms, and economies—underpin­ning its dynamics. This logic will be considered in light of what has been identified as mass me­dia logic, which has helped spread the media's powerful discourse outside its institutional boundaries. Theorizing social media logic, we identify four grounding principles—programmabil­ity, popularity, connectivity, and datafication—and argue that these principles become increas­ingly entangled with mass media logic. The logic of social media, rooted in these grounding principles and strategies, is gradually invading all areas of public life. Besides print news and broadcasting, it also affects law and order, social activism, politics, and so forth. Therefore, its sustaining logic and widespread dissemination deserve to be scrutinized in detail in order to better understand its impact in various domains. Concentrating on the tactics and strategies at work in social media logic, we reassess the constellation of power relationships in which social practices unfold, raising questions such as: How does social media logic modify or enhance ex­isting mass media logic? And how is this new media logic exported beyond the boundaries of (social or mass media proper? The underlying principles, tactics, and strategies may be relat­ively simple to identify, but it is much harder to map the complex connections between plat­forms that distribute this logic: users that employ them, technologies that

The Responsibility of the Delinquent Child

Directory of Open Access Journals (Sweden)

Osvaldo Agustín Marcón

2008-01-01

Full Text Available The discussion about how the prosecuted child should respond for criminal acts committed generates two dominant positions. One demands special ‘punishments’ while the other seeks ‘social and psychological responsibilization’. This article discusses both positions in the search for a synthesis that maintains the best elements of each. It thus proposes to guarantee fair trials, restricting the traditional judicial discretion in this field, but simultaneously rejecting the entire system of special punishments as a route for the construction of social and subjective responsibility. The alternative proposed is inserted in the field of Restorative Justice, in opposition to the Systems of Juvenile Penal Responsibility. It defends the notion of ‘co-responsibility sanction’ to substitute that defined as ‘responsibilization sanctions’, and of integral ‘guaranteeism’ instead of the notion of ‘penal guaranteeism’.

"We remain very much the second sex": the constructions of prostate cancer in popular news magazines, 2000-2010.

Science.gov (United States)

Miele, Rachelle; Clarke, Juanne

2014-01-01

Informed by social constructionism, biomedicalization, and a feminist framework, a discourse analysis was performed on 31 popular news articles published in North America between 2000 and 2010. The magazines construct prostate cancer in a gendered manner. Its construction is rooted in themes that are related to discussions of biology, prostate cancer as a heterosexual problem, the responsibilization of health and masculinity. Through these constructions, the popular news articles reinforce dominant ideals and performances of hegemonic masculinity and male sexuality, traditional femininity, and heteronormativity. While reinforcing such ideals, the prevention, treatment, and knowledge of prostate cancer is constructed as the responsibility of individual men. This study reveals that the articles favor discussions of heteronormativity and hegemonic masculinity over racism, rendering health inequalities silent.

Full Text Available The article is concerned with the results of the study, subject of which is the submis- sion of the respondents of the different age groups about the social and bold personality. Required property of the respondents was the presence in the Internet environment and participation in various social networks. They assessed social and bold personal- ity in such contexts of communication, as real communication and Internet communication. Analyses were undertaken to determine the structural and content features of emotional and semantic representations of the phenomenon of the social and bold personality, depending on the context of communication, but also the detection of age-sensitive representations of the young respondents (19—35 years, middle-aged respondents (36-55 years and older respondents (from 56 to 70 years. The concept of the “social and bold personality in real communion” is shown to have a high semantic relevance, strongly marked positive emotional coloration and a similar factor structure for respondents of all age groups. The concept of the “social and bold personality in online communication” with a high semantic significance in the perception of the young respondents moves into a zone of moderate and semantic importance in representations of the middle-aged and older respondents. In representations of the respondents of all age groups, the attractiveness of the "social and bold personality in Internet communication" is less than in comparison with the "social and bold personality in the real communication". The age-specific of the social representations about social and bold personality in the real and virtual communication has been analysed in detail.

Effect of inter-train interval on the induction of repetition suppression of motor-evoked potentials using transcranial magnetic stimulation.

Directory of Open Access Journals (Sweden)

Minna Pitkänen

Full Text Available Repetition suppression (RS is evident as a weakened response to repeated stimuli after the initial response. RS has been demonstrated in motor-evoked potentials (MEPs induced with transcranial magnetic stimulation (TMS. Here, we investigated the effect of inter-train interval (ITI on the induction of RS of MEPs with the attempt to optimize the investigative protocols. Trains of TMS pulses, targeted to the primary motor cortex by neuronavigation, were applied at a stimulation intensity of 120% of the resting motor threshold. The stimulus trains included either four or twenty pulses with an inter-stimulus interval (ISI of 1 s. The ITI was here defined as the interval between the last pulse in a train and the first pulse in the next train; the ITIs used here were 1, 3, 4, 6, 7, 12, and 17 s. RS was observed with all ITIs except with the ITI of 1 s, in which the ITI was equal to ISI. RS was more pronounced with longer ITIs. Shorter ITIs may not allow sufficient time for a return to baseline. RS may reflect a startle-like response to the first pulse of a train followed by habituation. Longer ITIs may allow more recovery time and in turn demonstrate greater RS. Our results indicate that RS can be studied with confidence at relatively short ITIs of 6 s and above.

The interval of mouse chromosome 1 extending from Idh-1 to Pep-3 harbors the natural resistance gene Ity/Lsh/Bcg; it controls the outcome of infection with Salmonella typhimurium, Leishmania donovani, and several Mycobacterium species. This region also contains a DNA repair gene, Rep-1, which determines the rapidity with which double-strand breaks in chromatin are repaired. BALB/cAnPt and DBA/2N mice differ in their phenotypic expression of these genes. To generate appropriate strains of mice for the study of these genes, a series of 10 C.D2 congenic strains recombinant across a 28-centimorgan interval of mouse chromosome 1 extending from Idh-1 to Pep-3 were derived from crosses of the C.D2-Idh-1 Pep-3 congenic strain back to BALB/cAn. Analyses of these recombinant strains will allow the correlation of biological-immunological phenotypes with defined genetic regions.

Recently, it has been shown that inter-transaction interval (ITI) distribution of foreign currency rates has a fat tail. In order to understand the statistical property of the ITI dealer model with N interactive agents is proposed. From numerical simulations it is confirmed that the ITI distribution of the dealer model has a power law tail. The random multiplicative process (RMP) can be approximately derived from the ITI of the dealer model. Consequently, we conclude that the power law tail of the ITI distribution of the dealer model is a result of the RMP.

Salmonella enterica is a ubiquitous Gram-negative intracellular bacterium that continues to pose a global challenge to human health. The etiology of Salmonella pathogenesis is complex and controlled by pathogen, environmental, and host genetic factors. In fact, patients immunodeficient in genes in the IL-12, IL-23/IFN-γ pathway are predisposed to invasive nontyphoidal Salmonella infection. Using a forward genomics approach by N-ethyl-N-nitrosourea (ENU) germline mutagenesis in mice, we identified the Ity14 (Immunity to Typhimurium locus 14) pedigree exhibiting increased susceptibility following in vivo Salmonella challenge. A DNA-binding domain mutation (p.G418_E445) in Stat4 (Signal Transducer and Activator of Transcription Factor 4) was the causative mutation. STAT4 signals downstream of IL-12 to mediate transcriptional regulation of inflammatory immune responses. In mutant Ity14 mice, the increased splenic and hepatic bacterial load resulted from an intrinsic defect in innate cell function, IFN-γ-mediated immunity, and disorganized granuloma formation. We further show that NK and NKT cells play an important role in mediating control of Salmonella in Stat4(Ity14/Ity14) mice. Stat4(Ity14/Ity14) mice had increased expression of genes involved in cell-cell interactions and communication, as well as increased CD11b expression on a subset of splenic myeloid dendritic cells, resulting in compromised recruitment of inflammatory cells to the spleen during Salmonella infection. Stat4(Ity14/Ity14) presented upregulated compensatory mechanisms, although inefficient and ultimately Stat4(Ity14/Ity14) mice develop fatal bacteremia. The following study further elucidates the pathophysiological impact of STAT4 during Salmonella infection.

Full Text Available This study examined the young children’s abilities to switch from rhythm production, with short 15 Inter-Taps Intervals (ITI, to temporal interval production, with long ITI (> 1 s, in a sensorimotor synchronization task. Children aged 3 and 5 years old were given 6 sessions of synchronization. In a control group, they had to synchronize their ITI to an Inter-Stimulus Interval (ISI of 4 s. In the experimental group, they must progressively increase their ITI for one session to the next (from 0.4-s to 4.0-s ISI. Our results showed that the 5-year-olds produced longer ITI that the 3-year-olds in synchronization. However, the value of ITI in the 5-year-olds never exceeded 1.5 s, with more variable ITI in the control than in the experimental group. In addition, at 5 years, boys had more difficulties than girls in changing their tapping rhythm. These results suggest a temporal window in sensorimotor synchronization, beyond which the rhythm is lost and the synchronization becomes difficult.

In the setting of chronic diseases, cost-utility analysis, which takes into account the beneficial effects of a given treatment/health care intervention in terms of health-related quality of life, is likely to be the most appropriate approach.Objective: The aim of this study was to assess the incremental cost-effectiveness ratios of immune tolerance induction (ITI therapy with plasma-derived factor VIII concentrates versus on-demand treatment with recombinant-activated FVIIa (rFVIIa in hemophilia A with high titer inhibitors from an Iranian Ministry of Health perspective.Methods: This study was based on the study of Knight et al, which evaluated the cost-effectiveness ratios of different treatments for hemophilia A with high-responding inhibitors. To adapt Knight et al's results to the Iranian context, a few clinical parameters were varied, and cost data were replaced with the corresponding Iranian estimates of resource use. The time horizon of the analysis was 10 years. One-way sensitivity analyses were performed, varying the cost of the clotting factor, the drug dose, and the administration frequency, to test the robustness of the analysis.Results: Comparison of the incremental cost-effectiveness ratios between the three ITI protocols and the on-demand regimen with rFVIIa shows that all three ITI protocols dominate the on-demand regimen with r

Uniting Resilience Research and Practice With an Inequalities Approach

Directory of Open Access Journals (Sweden)

Angie Hart

2016-12-01

Full Text Available The concept of resilience has evolved, from an individual-level characteristic to a wider ecological notion that takes into account broader person–environment interactions, generating an increased interest in health and well-being research, practice and policy. At the same time, the research and policy-based attempts to build resilience are increasingly under attack for responsibilizing individuals and maintaining, rather than challenging, the inequitable structure of society. When adversities faced by children and young people result from embedded inequality and social disadvantage, resilience-based knowledge has the potential to influence the wider adversity context. Therefore, it is vital that conceptualizations of resilience encompass this potential for marginalized people to challenge and transform aspects of their adversity, without holding them responsible for the barriers they face. This article outlines and provides examples from an approach that we are taking in our research and practice, which we have called Boingboing resilience. We argue that it is possible to bring resilience research and practice together with a social justice approach, giving equal and simultaneous attention to individuals and to the wider system. To achieve this goal, we suggest future research should have a co-produced and inclusive research design that overcomes the dilemma of agency and responsibility, contains a socially transformative element, and has the potential to empower children, young people, and families.

Finding Community Structures In Social Activity Data

KAUST Repository

Peng, Chengbin

2015-05-19

Social activity data sets are increasing in number and volume. Finding community structure in such data is valuable in many applications. For example, understand- ing the community structure of social networks may reduce the spread of epidemics or boost advertising revenue; discovering partitions in tra c networks can help to optimize routing and to reduce congestion; finding a group of users with common interests can allow a system to recommend useful items. Among many aspects, qual- ity of inference and e ciency in finding community structures in such data sets are of paramount concern. In this thesis, we propose several approaches to improve com- munity detection in these aspects. The first approach utilizes the concept of K-cores to reduce the size of the problem. The K-core of a graph is the largest subgraph within which each node has at least K connections. We propose a framework that accelerates community detection. It first applies a traditional algorithm that is relatively slow to the K-core, and then uses a fast heuristic to infer community labels for the remaining nodes. The second approach is to scale the algorithm to multi-processor systems. We de- vise a scalable community detection algorithm for large networks based on stochastic block models. It is an alternating iterative algorithm using a maximum likelihood ap- proach. Compared with traditional inference algorithms for stochastic block models, our algorithm can scale to large networks and run on multi-processor systems. The time complexity is linear in the number of edges of the input network. The third approach is to improve the quality. We propose a framework for non- negative matrix factorization that allows the imposition of linear or approximately linear constraints on each factor. An example of the applications is to find community structures in bipartite networks, which is useful in recommender systems. Our algorithms are compared with the results in recent papers and their quality and e

Interaction with extracellular matrix proteins influences Lsh/Ity/Bcg (candidate Nramp) gene regulation of macrophage priming/activation for tumour necrosis factor-alpha and nitrite release.

The murine resistance gene Lsh/Ity/Bcg regulates activation of macrophages for tumour necrosis factor-alpha (TNF-alpha)-dependent production of nitric oxide mediating antimicrobial activity against Leishmania, Salmonella and Mycobacterium. As Lsh is differentially expressed in macrophages from different tissue sites, experiments were performed to determine whether interaction with extracellular matrix (ECM) proteins would influence the macrophage TNF-alpha response. Plating of bone marrow-derived macrophages onto purified fibrinogen or fibronectin-rich L929 cell-derived matrices, but not onto mannan, was itself sufficient to stimulate TNF-alpha release, with significantly higher levels released from congenic B10.L-Lshr compared to C57BL/10ScSn (Lshs) macrophages. Only macrophages plated onto fibrinogen also released measurable levels of nitrites, again higher in Lshr compared to Lshs macrophages. Addition of interferon-gamma (IFN-gamma), but not bacterial lipopolysaccharide or mycobacterial lipoarabinomannan, as a second signal enhanced the TNF-alpha and nitrite responses of macrophages plated onto fibrinogen, particularly in the Lshr macrophages. Interaction with fibrinogen and fibronectin also primed macrophages for an enhanced TNF-alpha response to leishmanial parasites, but this was only translated into enhanced nitrite responses in the presence of IFN-gamma. In these experiments, Lshr macrophages remained superior in their TNF-alpha responses throughout, but to a degree which reflected the magnitude of the difference observed on ECM alone. Hence, the specificity for the enhanced TNF-alpha responses of Lshr macrophages lay in their interaction with fibrinogen and fibronectin ECM, while a differential nitrite response was only observed with fibrinogen and/or IFN-gamma. The results are discussed in relation to the possible function of the recently cloned candidate gene Nramp, which has structural identity to eukaryote transporters and an N-terminal cytoplasmic

Intratesticular injection (ITI) of sodium chloride (NaCl) is efficient for chemical castration of young calves, but its effects on calves welfare are unknown. Two experiments were conducted to evaluate the effects of ITI of 20% NaCl on stress and inflammatory markers in calves less than 20 days old and to assess the efficiency of ITI of 30% NaCl in 5 months old calves. In Experiment 1, control calves were only restrained and compared to calves submitted to castration through surgery (SC) and ITI with 20% NaCl (n = 9/group). No differences were observed for the eye corner temperature measured by thermography from 60 s before to 60 s after the procedures (P > 0.05). In the SC group, acute serum cortisol levels increased at 30 and 60 min after the procedure, but increased levels in the ITI group occurred only at 30 min (P  0.05). Scrotal temperature was higher at D1 in the SC group than for the other groups, but lowest at D4 compared to the control (both P castration through ITI of 20% NaCl in young calves was followed by slight stress and inflammatory responses compared to surgical castration. However, ITI of 30% NaCl was ineffective for chemical castration of 5 months old calves. Copyright © 2016 Elsevier Inc. All rights reserved.

Application methods of infrared thermal images in the health care field of traditional Chinese medicine

2008-12-01

Infrared thermal imaging (ITI) is the potential imaging technique for the health care field of traditional Chinese medicine (TCM). Successful application demands obeying the characteristics and regularity of the ITI of human body and designing rigorous trials. First, the influence of time must be taken into account as the ITI of human body varies with time markedly. Second, relative magnitude is preferred to be the index of the image features. Third, scatter diagrams and the method of least square could present important information for evaluating the health care effect. A double-blind placebo-controlled randomized trial was undertaken to study the influences of Shengsheng capsule, one of the TCM health food with immunity adjustment function, on the ITI of human body. The results showed that the effect of Shengsheng capsule to people with weak constitution or in the period of being weak could be reflected objectively by ITI. The relative efficacy rate was 81.3% for the trial group and 30.0% for the control group, there was significant difference between the two groups (P=0.003). So the sensitivity and objectivity of ITI are of great importance to the health care field of TCM.

Pharmacological evidence that both cognitive memory and habit formation contribute to within-session learning of concurrent visual discriminations.

The monkey's ability to learn a set of visual discriminations presented concurrently just once a day on successive days (24-h ITI task) is based on habit formation, which is known to rely on a visuo-striatal circuit and to be independent of visuo-rhinal circuits that support one-trial memory. Consistent with this dissociation, we recently reported that performance on the 24-h ITI task is impaired by a striatal-function blocking agent, the dopaminergic antagonist haloperidol, and not by a rhinal-function blocking agent, the muscarinic cholinergic antagonist scopolamine. In the present study, monkeys were trained on a short-ITI form of concurrent visual discrimination learning, one in which a set of stimulus pairs is repeated not only across daily sessions but also several times within each session (in this case, at about 4-min ITIs). Asymptotic discrimination learning rates in the non-drug condition were reduced by half, from approximately 11 trials/pair on the 24-h ITI task to approximately 5 trials/pair on the 4-min ITI task, and this faster learning was impaired by systemic injections of either haloperidol or scopolamine. The results suggest that in the version of concurrent discrimination learning used here, the short ITIs within a session recruit both visuo-rhinal and visuo-striatal circuits, and that the final performance level is driven by both cognitive memory and habit formation working in concert.

Between-Trial Forgetting Due to Interference and Time in Motor Adaptation.

Directory of Open Access Journals (Sweden)

Sungshin Kim

Full Text Available Learning a motor task with temporally spaced presentations or with other tasks intermixed between presentations reduces performance during training, but can enhance retention post training. These two effects are known as the spacing and contextual interference effect, respectively. Here, we aimed at testing a unifying hypothesis of the spacing and contextual interference effects in visuomotor adaptation, according to which forgetting between trials due to either spaced presentations or interference by another task will promote between-trial forgetting, which will depress performance during acquisition, but will promote retention. We first performed an experiment with three visuomotor adaptation conditions: a short inter-trial-interval (ITI condition (SHORT-ITI; a long ITI condition (LONG-ITI; and an alternating condition with two alternated opposite tasks (ALT, with the same single-task ITI as in LONG-ITI. In the SHORT-ITI condition, there was fastest increase in performance during training and largest immediate forgetting in the retention tests. In contrast, in the ALT condition, there was slowest increase in performance during training and little immediate forgetting in the retention tests. Compared to these two conditions, in the LONG-ITI, we found intermediate increase in performance during training and intermediate immediate forgetting. To account for these results, we fitted to the data six possible adaptation models with one or two time scales, and with interference in the fast, or in the slow, or in both time scales. Model comparison confirmed that two time scales and some degree of interferences in either time scale are needed to account for our experimental results. In summary, our results suggest that retention following adaptation is modulated by the degree of between-trial forgetting, which is due to time-based decay in single adaptation task and interferences in multiple adaptation tasks.

Controversy exists regarding optimal caliper placement in ultrasound assessment of maximum abdominal aortic diameter. This study aimed primarily to determine reproducibility of caliper placement in relation to the aortic wall with the three principal methods: leading to leading edge (LTL), inner to inner edge (ITI), and outer to outer edge (OTO). The secondary aim was to assess the mean difference between the OTO, ITI, and LTL diameters and estimate the impact of using either of these methods on abdominal aortic aneurysm (AAA) prevalence in a screening program. Radiologists (n=18) assessed the maximum antero-posterior abdominal aortic diameter by completing repeated caliper placements with the OTO, LTL, and ITI methods on 50 still abdominal aortic images obtained from an AAA screening program. Inter-observer reproducibility was calculated as the limit of agreement with the mean (LoA), which represents expected deviation of a single observer from the mean of all observers. Intra-observer reproducibility was assessed averaging the LoA for each observer with their repeated measurements. Based on data from an AAA screening trial and the estimated mean differences between the three principal methods, AAA prevalence was estimated using each of the methods. The inter-observer LoA of the OTO, ITI, and LTL was 2.6, 1.9, and 1.9 mm, whereas the intra-observer LoA was 2.0, 1.6, and 1.5 mm, respectively. Mean differences of 5.0 mm were found between OTO and ITI measurements, 2.6 mm between OTO and LTL measurements, and 2.4 mm between LTL and ITI measurements. The prevalence of AAA almost doubled using OTO instead of ITI, while the difference between ITI and LTL was minor (3.3% vs. 4.0% AAA). The study shows superior reproducibility of LTL and ITI compared with the OTO method of caliper placement in ultrasound determination of maximum abdominal aortic diameter, and the choice of caliper placement method significantly affects the prevalence of AAAs in screening programs

It is of great importance to study the manifestations and the influencing factors of the time-related changes of infrared thermal images (ITI) of human body since the variable body surface temperature distribution seriously affected the application of ITI in medicine. In this paper, manifestations of time-related changes of the ITI of human body from three double-blind randomized trials and their correlation with meteorological factors (e.g. temperature, pressure, humidity, cold front passage and tropical cyclone landing) were studied. The trials were placebo or drug controlled studying the influences of Chinese medicine health food (including Shengsheng capsule with immunity adjustment function, Shengan capsule with sleep improvement function and Shengyi capsule with the function of helping to decrease serum lipid) on the ITI of human body. In the first thirty-six days of the trials images were scanned every six days and image data in the seven observation time spots (including the 0, 6, 12, 18, 24, 30, 36 day of the trial) were used for the time-related study. For every subject the scanned time was fixed in the day within two hours. The ITI features which could reflect the functions of the health foods were studied. The indexes of the features were relative magnitude (temperature difference between the viewing area and the reference area). Results showed that the variation tendencies of the trial group and control group were basically the same in placebo controlled trials and some of the long-term effects of Chinese medicine health food could be reflected significantly in certain time spots in the first thirty-six days. Time-related changes of the ITI of human body were closely related with meteorological factors but there were other influencing factors still need to be studied. As the ITI of human body could reflect the influences of Chinese medicine health foods and are closely related with meteorology, there are bright prospects for the application of ITI in

2013-01-01

There have been significant developments in health education over recent years. Focusing on France, the purpose of this paper is to examine the role of health education in reducing social inequalities based on the example of the Atelier santé ville de Cahors (Cahors Health Workshop). The paper addresses the following questions: What are the results and outcomes of the workshop? What kind of health education issues are at stake in the territorial approach to policy-making in an urban context? We examined the methods underlying the health education measures taken in the Cahors Health Workshop, which involve project-based approaches and the promotion of community health. Health education aimed at improving health is central to issues such as listening and speaking, the development of autonomy and the responsibilization of urban actors. Based on a rigorous methodology and the underlying values, health education in the Cahors Health Workshop places local residents, elected representatives and health professionals at the heart of the health care process (from the diagnostic process to the assessment process) and contributes to the reduction of social inequalities in health while facilitating access to information and health care. The goal of health education is to encourage individuals to be responsible for their own health in order to empower them to make informed choices adapted to the demands of their environment.

We discuss the design of suitable molecular systems and the methods that may monitor the 'performance' of such a machine

QUESTÃO SOCIAL HOJE : A RESISTÊNCIA UM ELEMENTO EM CONSTRUÇÃO (THE SOCIAL QUESTION TODAY: THE RESISTENCE AS EM ELEMENT IN CONSTRUCTION

. The social question, basically composed of the economic and political elements, now may by manifested as pauperism. That one that perceives it taking consciousness and denouncing it, demanding another attendance, becomes the element of resistance, capable to inscribe this problem in the political agenda.I understand that in the social question today this element of the resistance is in construction. To arrive to this we point out what in the past was called “the classic social question” (XIX th. Century, from the resultant pauperism of the industrial revolution. We consider pauperism as “the son of industrialization”. Considering the political elements itis expressed in the organization and formation of the labor class, their unions, the left political parties, assuming the protagonism of the social question. To point out the social question today we have to detect the contradictions wich are revealed from the reorganization of the production, since the end of the last century and the beginning of the present, affirmed in the version of the “mundialização financeira”. It makes flexible and turns unsafe the work relations causing a structural unemployment, because “unloked” of the work weaken the “steady ones even though”.In the social question today there are, therefore, new manifestations of poverty, from the productive reorganization, but the actors and citizens to denounce this situation and to define a more favorable project, is an element still in construction.

Full Text Available OBJECTIVE: Although enzyme replacement therapy (ERT is a highly effective therapy, CRIM-negative (CN infantile Pompe disease (IPD patients typically mount a strong immune response which abrogates the efficacy of ERT, resulting in clinical decline and death. This study was designed to demonstrate that immune tolerance induction (ITI prevents or diminishes the development of antibody titers, resulting in a better clinical outcome compared to CN IPD patients treated with ERT monotherapy. METHODS: We evaluated the safety, efficacy and feasibility of a clinical algorithm designed to accurately identify CN IPD patients and minimize delays between CRIM status determination and initiation of an ITI regimen (combination of rituximab, methotrexate and IVIG concurrent with ERT. Clinical and laboratory data including measures of efficacy analysis for response to ERT were analyzed and compared to CN IPD patients treated with ERT monotherapy. RESULTS: Seven CN IPD patients were identified and started on the ITI regimen concurrent with ERT. Median time from diagnosis of CN status to commencement of ERT and ITI was 0.5 months (range: 0.1-1.6 months. At baseline, all patients had significant cardiomyopathy and all but one required respiratory support. The ITI regimen was safely tolerated in all seven cases. Four patients never seroconverted and remained antibody-free. One patient died from respiratory failure. Two patients required another course of the ITI regimen. In addition to their clinical improvement, the antibody titers observed in these patients were much lower than those seen in ERT monotherapy treated CN patients. CONCLUSIONS: The ITI regimen appears safe and efficacious and holds promise in altering the natural history of CN IPD by increasing ERT efficacy. An algorithm such as this substantiates the benefits of accelerated diagnosis and management of CN IPD patients, thus, further supporting the importance of early identification and treatment

Full Text Available The SIMPOL.1 group contribution method is developed for predicting the liquid vapor pressure p^o_L (atm and enthalpy of vaporization Δ H_vap (kJ mol^-1 of organic compounds as functions of temperature (<i>T>. For each compound i, the method assumes log₁₀p^o_L,i (T=∑_kν_k,ib_k(T where ν_k,i is the number of groups of type k, and b_k (<i>T> is the contribution to log₁₀p^o_L,i (<i>T> by each group of type k. A zeroeth group is included that uses b₀ (<i>T> with ν_0,i=1 for all i. A total of 30 structural groups are considered: molecular carbon, alkyl hydroxyl, aromatic hydroxyl, alkyl ether, alkyl ring ether, aromatic ether, aldehyde, ketone, carboxylic acid, ester, nitrate, nitro, alkyl amine (primary, secondary, and tertiary, aromatic amine, amide (primary, secondary, and tertiary, peroxide, hydroperoxide, peroxy acid, C=C, carbonylperoxynitrate, nitro-phenol, nitro-ester, aromatic rings, non-aromatic rings, C=C–C=O in a non-aromatic ring, and carbon on the acid-side of an amide. The <i>T> dependence in each of the b_k (<i>T> is assumed to follow b(T=B₁/T+B₂+B₃T+B₄ln <i>T>. Values of the B coefficients are fit using an initial basis set of 272 compounds for which experimentally based functions p^o _L,i=f_i (<i>T> are available. The range of vapor pressure considered spans fourteen orders of magnitude. The ability of the initially fitted B coefficients to predict p^o_L values is examined using a test set of 184 compounds and a <i>T> range that is as wide as 273

Precarious beginnings: Gendered risk discourses in psychiatric research literature about postpartum depression.

Science.gov (United States)

Godderis, Rebecca

2010-09-01

The transition to motherhood in western society is particularly informed by risk-based scientific and medical discourses and, as a result, women are especially subject to rationalities and practices that are employed in the name of risk. The aim of this article is to examine the gendered risk discourses that are embedded in one aspect of medicalized mothering - the postpartum period. This article interrogates three key elements of the discursive construction of postpartum depression (PPD) in contemporary psychiatric research literature (approximately 1980-2007). Specifically, I examine how risk-based reasoning is incorporated into the concepts of the postpartum triad and the high-risk mother, and how arguments about why PPD is a 'significant social problem' create a tension between the rights of the mother and those of the child. By placing women in a position to manage certain types of risks related to the postpartum period, these discourses serve to responsibilize women and structure their subjectivities in gendered ways.This analysis contributes to a growing literature that investigates how assumptions about gender, race, class and sexuality are produced and re-produced through the notion of risk.

Castration of male calves is necessary for trading to facilitate handling and prevent reproduction. However, some methods of castration are traumatic and lead to economic losses because of infection and myiasis. The objective of the present study was to evaluate the efficiency of intratesticular injection (ITI) of hypertonic sodium chloride (NaCl; 20%) solution in male calf castration during the first weeks of life. Forty male calves were allocated to one of the following experimental groups: negative control-surgically castrated immediately after birth; positive control -intact males; G1-ITI from 1- to 5-day old; G2-ITI from 15- to 20-day old; and G3-ITI from 25- to 30-day old. Intratesticular injection induced coagulative necrosis of Leydig cells and seminiferous tubules leading to extensive fibrosis. Testosterone secretion and testicular development were severely impaired in 12-month-old animals from G1 and G2 groups (P<0.05), in which no testicular structure and sperm cells were observed during breeding soundness evaluation. Rectal and scrotal temperatures were not affected by different procedures. In conclusion, ITI of hypertonic NaCl solution induces sterility and completely suppresses testosterone secretion when performed during the first 20 days of life. Copyright © 2014 Elsevier Inc.

Thermophilic, aerobic bacteria isolated from Icelandic hot springs were screened for xylanase activity. Of 97 strains tested, 14 were found to be xylanase positive. Xylanase activities up to 12 nkat/ml were produced by these strains in shake flasks on xylan medium. The xylanases of the two strains producing the highest activities (ITI 36 and ITI 283) were similar with respect to temperature and pH optima (80deg C and pH 8.0). Xylanase production of strain ITI 36 was found to be induced by xylan and xylose. Xylanase activity of 24 nkat/ml was obtained with this strain in a laboratory-scale-fermentor cultivation on xylose medium. [beta]-Xylosidase activity was also detected in the culture filtrate. The thermal half-life of ITI 36 xylanase was 24 h at 70deg C. The highest production of sugars from hydrolysis of beech xylan was obtained at 70deg C, although xylan depolymerization was detected even up to 90deg C. (orig.).

The authors examined temporal trends and correlates of HIV testing frequency among men who have sex with men (MSM) in King County, Washington. The authors evaluated data from MSM testing for HIV at the Public Health-Seattle & King County (PHSKC) STD Clinic and Gay City Health Project (GCHP) and testing history data from MSM in PHSKC HIV surveillance. The intertest interval (ITI) was defined as the number of days between the last negative HIV test and the current testing visit or first positive test. Correlates of the log(10)-transformed ITI were determined using generalised estimating equations linear regression. Between 2003 and 2010, the median ITI among MSM seeking HIV testing at the STD Clinic and GCHP were 215 (IQR: 124-409) and 257 (IQR: 148-503) days, respectively. In multivariate analyses, younger age, having only male partners and reporting ≥10 male sex partners in the last year were associated with shorter ITIs at both testing sites (pGCHP attendees, having a regular healthcare provider, seeking a test as part of a regular schedule and inhaled nitrite use in the last year were also associated with shorter ITIs (pGCHP (median 359 vs 255 days, p=0.02). Although MSM in King County appear to be testing at frequent intervals, further efforts are needed to reduce the time that HIV-infected persons are unaware of their status.

One of the main objective of the WP7 (Strategic Applications and Capacity Building) in the framework of the REAKT-Strategies and tools for Real Time Earthquake RisK ReducTion FP7 European project, is to evaluate the effectiveness of EEW and real-time risk assessment procedures in reducing seismic risk to various industrial partners and end-users. In the context of the REAKT project, the AMRA-RISSCLab group is engaged in a feasibility study on the application of earthquake early-warning procedures in two high schools located in the Irpinia region (South Italy), an area that in the 1980 was struck by a magnitude 6.9 earthquake. In this work we report on the activities carried out during the last 24 Months at the school ITIS 'E. Majorana', located in Somma Vesuviana, a village in the neighbourhood of Naples. In order to perform a continuous seismic monitoring of the site, which includes a rather complex structure building, 5 accelerometric stations have been installed in different part of the school. In particular, a 24-bit ADC (Sigma/Delta) Agecodagis-Kefren data-logger has been installed with a Guralp CMG-5TC accelerometer with a 0.25g full-scale in the school courtyard, while 4 SOSEWIN sensors have been also installed at different locations within the building. Commercial ADSL lines provide transmission of real-time data to the EEW centre. Data streams are now acquired in real-time in the PRESToPlus (regional and on-site, threshold-based early-warning) software platform [1]. The recent December 29, 2013 M 5.1 Monti del Matese Earthquake, gave us the unique opportunity to use real strong motion data to test the performance of threshold-based early warning method at the school. The on-site method [2] aims to define alert levels at the monitored site. In particular, at each station the characteristic P-waves period (τc) and the peak displacement (Pd) are measured on the initial P-wave signal. They are compared with threshold values, previously established through an

Balanced Scorecard (BSC) is a powerful tool in decision making process. Nevertheless, it is not rare that the BSC does not give satisfactory results because the indicators chosen do not reflect the needs of the organization. Therefore, indicator establishment is very crucial in the utilization of BSC. This research aims to determine the indicators BSC for a university and the research is a case study in Institut Teknologi Indonesia (ITI). In this study, BSC structure and indicators, comparison made by 4 previous researchers was used as the initial guide to determine the structure and indicators of ITI. And then, questionnaires were distributed to selected respondents and a focus group discussion (FGD) was conducted in order to produce indicators of BSC based on the mental model of the ITI. It is found 15 indicators based on the mental model of ITI. Furthermore, the relationships between the indicators are seen as dynamic relationships, and by using system dynamics, some feedback loops that are considered critical to organizational success can be identified and isolated.

Interaction of acridine-calix[4]arene with DNA at the electrified liquid liquid interface

The behaviour of an acridine-functionalised calix[4]arene at the interface between two immiscible electrolyte solutions (ITIES) is reported. Molecular modelling showed that the acridine-calix[4]arene has regions of significant net positive charge spread throughout the protonated acridine moieties, consistent with it being able to function as an anion ionophore. The presence of this compound in the organic phase facilitated the transfer of aqueous phase electrolyte ions. Upon addition of double stranded DNA to the aqueous phase, the transfer of electrolyte anions was diminished, due to DNA binding to the acridine moiety at the ITIES. The behaviour provides a basis for DNA hybridization detection using electrochemistry at the ITIES.

Inter-track interference mitigation with two-dimensional variable equalizer for bit patterned media recording

Directory of Open Access Journals (Sweden)

Yao Wang

2017-05-01

Full Text Available The increased track density in bit patterned media recording (BPMR causes increased inter-track interference (ITI, which degrades the bit error rate (BER performance. In order to mitigate the effect of the ITI, signals from multiple tracks can be equalized by a 2D equalizer with 1D target. Usually, the 2D fixed equalizer coefficients are obtained by using a pseudo-random bit sequence (PRBS for training. In this study, a 2D variable equalizer is proposed, where various sets of 2D equalizer coefficients are predetermined and stored for different ITI patterns besides the usual PRBS training. For data detection, as the ITI patterns are unknown in the first global iteration, the main and adjacent tracks are equalized with the conventional 2D fixed equalizer, detected with Bahl-Cocke-Jelinek-Raviv (BCJR detector and decoded with low-density parity-check (LDPC decoder. Then using the estimated bit information from main and adjacent tracks, the ITI pattern for each island of the main track can be estimated and the corresponding 2D variable equalizers are used to better equalize the bits on the main track. This process is executed iteratively by feeding back the main track information. Simulation results indicate that for both single-track and two-track detection, the proposed 2D variable equalizer can achieve better BER and frame error rate (FER compared to that with the 2D fixed equalizer.

Why are Some Games More Addictive than Others: The Effects of Timing and Payoff on Perseverance in a Slot Machine Game.

Manipulating different behavioral characteristics of gambling games can potentially affect the extent to which individuals persevere at gambling, and their transition to problematic behaviors. This has potential impact for mobile gambling technologies and responsible gambling interventions. Two laboratory models pertinent to this are the partial reinforcement extinction effect (PREE) and the trial spacing effect. Both of these might speed up or delay the acquisition and extinction of conditioned behavior. We report an experiment that manipulated the rate of reinforcement and inter trial interval (ITI) on a simulated slot machine where participants were given the choice between gambling and skipping on each trial, before perseverative gambling was measured in extinction, followed by measurements of the illusion of control, depression and impulsivity. We hypothesized that longer ITI's in conjunction with the low rates of reinforcement observed in gambling would lead to greater perseverance. We further hypothesized, given that timing is known to be important in displaying illusory control and potentially in persevering in gambling, that prior exposure to longer intervals might affect illusions of control. An interaction between ITI and rate of reinforcement was observed, as low reinforced gamblers with a long ITI gambled for longer. Respondents also displayed extinction and a PREE. Gamblers exposed to a higher rate of reinforcement gambled for longer in acquisition. Impulsivity was associated with extended perseverance in extinction, and more depressed gamblers in the high reinforcement short ITI group persevered for longer. Performance in the contingency judgment failed to support the second hypothesis: the only significant contrast observed was that participants became better calibrated as the task progressed.

From near-surface to root-zone soil moisture using an exponential filter: an assessment of the method based on in-situ observations and model simulations

Directory of Open Access Journals (Sweden)

C. Albergel

2008-12-01

Full Text Available A long term data acquisition effort of profile soil moisture is under way in southwestern France at 13 automated weather stations. This ground network was developed in order to validate remote sensing and model soil moisture estimates. In this paper, both those in situ observations and a synthetic data set covering continental France are used to test a simple method to retrieve root zone soil moisture from a time series of surface soil moisture information. A recursive exponential filter equation using a time constant, <i>T>, is used to compute a soil water index. The Nash and Sutcliff coefficient is used as a criterion to optimise the <i>T> parameter for each ground station and for each model pixel of the synthetic data set. In general, the soil water indices derived from the surface soil moisture observations and simulations agree well with the reference root-zone soil moisture. Overall, the results show the potential of the exponential filter equation and of its recursive formulation to derive a soil water index from surface soil moisture estimates. This paper further investigates the correlation of the time scale parameter <i>T> with soil properties and climate conditions. While no significant relationship could be determined between <i>T> and the main soil properties (clay and sand fractions, bulk density and organic matter content, the modelled spatial variability and the observed inter-annual variability of <i>T> suggest that a weak climate effect may exist.

Measurement of motivation and cognitive load has potential value in health professions education. Our objective was to evaluate the validity of scores from Dweck's Implicit Theories of Intelligence Scale (ITIS), Elliot's Achievement Goal Questionnaire-Revised (AGQ-R) and Leppink's cognitive load index (CLI). This was a validity study evaluating internal structure using reliability and factor analysis, and relationships with other variables using the multitrait-multimethod matrix. Two hundred and thirty-two secondary school students participated in a medical simulation-based training activity at an academic medical center. Pre-activity ITIS (implicit theory [mindset] domains: incremental, entity) and AGQ-R (achievement goal domains: mastery-approach, mastery-avoidance, performance-approach, performance-avoidance), post-activity CLI (cognitive load domains: intrinsic, extrinsic, germane) and task persistence (self-directed repetitions on a laparoscopic surgery task) were measured. Internal consistency reliability (Cronbach's alpha) was > 0.70 for all domain scores except AGQ-R performance-avoidance (alpha 0.68) and CLI extrinsic load (alpha 0.64). Confirmatory factor analysis of ITIS and CLI scores demonstrated acceptable model fit. Confirmatory factor analysis of AGQ-R scores demonstrated borderline fit, and exploratory factor analysis suggested a three-domain model for achievement goals (mastery-approach, performance and avoidance). Correlations among scores from conceptually-related domains generally aligned with expectations, as follows: ITIS incremental and entity, r = -0.52; AGQ-R mastery-avoidance and performance-avoidance, r = 0.71; mastery-approach and performance-approach, r = 0.55; performance-approach and performance-avoidance, r = 0.43; mastery-approach and mastery-avoidance, r = 0.36; CLI germane and extrinsic, r = -0.35; ITIS incremental and AGQ-R mastery-approach, r = 0.34; ITIS incremental and CLI germane, r = 0.44; AGQ-R mastery

The aim of this study was to test the hypothesis that visual mismatch negativity (vMMN) is based on memory trace formation. Special care was taken to distinguish between memory mismatch and rareness effect. Subjects were seated in front of a monitor and asked to listen to a story. The standard sequence block consisted of nine consecutive 24-vane windmill patterns with an 800-ms inter-stimulus interval. The deviant sequence block consisted of one 24-vane pattern with eight six-vane patterns. Inter-train intervals (ITIs) varied among 1, 6, and 12s in the changing ITI experiment, while the deviant stimulus occupied the eighth position in the sequence. In the changing order experiment, the position of the deviant stimulus was varied among the second, fourth and eighth position with a 12-s constant ITI. vMMN was ascertained from the difference in responses to standard and deviant stimulus. vMMN appeared in the occipital region 150-300 ms after stimulus onset. It was significantly modulated by the ITI, and more than four preceding stimuli were needed to reinstate the implicit memory trace. These results suggest that memory-based change detection underlies vMMN. Therefore, vMMN is useful to study visual sensory memory function.

Paired Synchronous Rhythmic Finger Tapping without an External Timing Cue Shows Greater Speed Increases Relative to Those for Solo Tapping.

2017-03-09

In solo synchronization-continuation (SC) tasks, intertap intervals (ITI) are known to drift from the initial tempo. It has been demonstrated that people in paired and group contexts modulate their action timing unconsciously in various situations such as choice reaction tasks, rhythmic body sway, and hand clapping in concerts, which suggests the possibility that ITI drift is also affected by paired context. We conducted solo and paired SC tapping experiments with three tempos (75, 120, and 200 bpm) and examined whether tempo-keeping performance changed according to tempo and/or the number of players. Results indicated that those tapping in the paired conditions were faster, relative to those observed in the solo conditions, for all tempos. For the faster participants, the degree of ITI drift in the solo conditions was strongly correlated with that in the paired conditions. Regression analyses suggested that both faster and slower participants adapted their tap timing to that of their partners. A possible explanation for these results is that the participants reset the phase of their internal clocks according to the faster beat between their own tap and the partners' tap. Our results indicated that paired context could bias the direction of ITI drift toward decreasing.

Parameter estimation of brain tumors using intraoperative thermal imaging based on artificial tactile sensing in conjunction with artificial neural network

Sadeghi-Goughari, M; Mojra, A; Sadeghi, S

2016-01-01

Intraoperative Thermal Imaging (ITI) is a new minimally invasive diagnosis technique that can potentially locate margins of brain tumor in order to achieve maximum tumor resection with least morbidity. This study introduces a new approach to ITI based on artificial tactile sensing (ATS) technology in conjunction with artificial neural networks (ANN) and feasibility and applicability of this method in diagnosis and localization of brain tumors is investigated. In order to analyze validity and reliability of the proposed method, two simulations were performed. (i) An in vitro experimental setup was designed and fabricated using a resistance heater embedded in agar tissue phantom in order to simulate heat generation by a tumor in the brain tissue; and (ii) A case report patient with parafalcine meningioma was presented to simulate ITI in the neurosurgical procedure. In the case report, both brain and tumor geometries were constructed from MRI data and tumor temperature and depth of location were estimated. For experimental tests, a novel assisted surgery robot was developed to palpate the tissue phantom surface to measure temperature variations and ANN was trained to estimate the simulated tumor’s power and depth. Results affirm that ITI based ATS is a non-invasive method which can be useful to detect, localize and characterize brain tumors. (paper)

Progress toward inducing immunologic tolerance to factor VIII

OpenAIRE

Scott, David W.; Pratt, Kathleen P.; Miao, Carol H.

2013-01-01

A major problem in treating hemophilia A patients with therapeutic factor VIII (FVIII) is that 20% to 30% of these patients produce neutralizing anti-FVIII antibodies. These antibodies block (inhibit) the procoagulant function of FVIII and thus are termed “inhibitors.” The currently accepted clinical method to attempt to eliminate inhibitors is immune tolerance induction (ITI) via a protocol requiring intensive FVIII treatment until inhibitor titers drop. Although often successful, ITI is ext...

This report describes the process and results from an effort to develop metrics for program accomplishments for the FY 1997 budget submission of the U.S. Department of Energy Environmental Management International Technology Integration Program (EM-ITI). The four-step process included interviews with key EM-ITI staff, the development of a strawman program logic chart, and all day facilitated workshop with EM-ITI staff during which preliminary performance plans and measures were developed and refined, and a series of follow-on discussions and activities including a cross-organizational project data base. The effort helped EM-ITI to crystallize and develop a unified vision of their future which they can effectively communicate to their own management and their internal and external customers. The effort sets the stage for responding to the Government Performance and Results Act. The metrics developed may be applicable to other international technology integration programs. Metrics were chosen in areas of eight general performance goals for 1997-1998: (1) number of forums provided for the exchange of information, (2) formal agreements signed, (3) new partners identified, (4) customers reached and satisfied, (5, 6) dollars leveraged by EM technology focus area and from foreign research, (7) number of foreign technologies identified for potential use in remediation of DOE sites, and (8) projects advanced through the pipeline

[Intratympanic injection therapy for therapy refractory acute hearing loss: A safe option for secondary treatment].

Mühlmeier, G; Maier, S; Maier, M; Maier, H

2015-10-01

High-dose corticosteroids are currently recommended for idiopathic sudden sensorineural hearing loss (ISSNHL) treatment. Intratympanic injections (ITI) are of growing importance, especially in cases of therapy resistance. The selection of patients for this procedure in SSNHL has not been adequately examined so far. A total of 77 patients with ISSNHL after ineffective systemic pretreatment underwent intratympanic administration of dexamethasone and hyaluronic acid. Improvement after treatment was determined by pure tone audiometry for both ears before and of the treated ear after ITI. In this study 34 female and 43 male patients with mean age of 57 years showed a pre-ITI hearing loss of 35 dB in the lower frequencies and 69 dB in the higher frequencies. The mean hearing gain was 10 dB and the response rate was 62%. Absolute hearing gain revealed significant improvements at 500 Hz, 1 kHz and 2 kHz. Under inclusion of contralateral thresholds there were hardly any differences up to 4 kHz. In a detailed analysis of responders moderate improvements could be observed even in higher frequencies. Overall, no relevant adverse events occurred. Treatment of ISSNHL resistant to systemic regimens by ITI of steroids provides an option that offers additional prospects of auditory improvement for affected patients. The presented results indicate that these modalities are also valid for patients with pancochlear ISSNHL.

Full Text Available Deployment of Information Technology/Information Systems (IT/IS has been recognized as one of the potential means to supply information for timely business decision making. Despite growing importance of IT/IS in business, Small Medium Enterprises (SMEs embrace constant challenges to deploy IS effectively, and thus, hardly to optimize the IT/IS strategic values. In such situation, IS planning is getting paramount to promote more effective IT/IS management of the firms. This study reports IS planning practices of a manufacturing-based SME. The face to face interview has been carried out to explore IS planning activities in a chosen firm. The qualitative analysis suggests that the selected company did undergo the four phases of strategic IS planning process namely, planning, analysing, selection, and implementation. The owner act as the champion of the strategic IS planning process. Further, the owner and the employees plays an important role as a decision maker. Specifically, the owner decides mainly on acquiring a new technology related to the firm’s core business process whereas the users responsible on the selection of relevant application (s to be used in their respective departments. Apart from that, the owner also plays a role as a researcher for the new technology acquired whilst the users provide an input on the applications to be acquired.

Sorption and desorption of indaziflam degradates in several agricultural soils

Full Text Available ABSTRACT Processes regulating pesticide fate in the environment are influenced by the physicochemical properties of pesticides and soils. Sorption and desorption are important processes as they regulate the movement of pesticides in soil. Although sorption-desorption is widely studied for herbicides, studies involving their metabolites in soil are scarce. Sorption and desorption of indaziflam metabolites (indaziflam-triazinediamine (FDAT, indaziflam-triazine-indanone (ITI and indaziflam-carboxilic acid (ICA were investigated in six Brazilian (BRA soils and three United States (USA soils with different physicochemical properties. The Freundlich equation described sorption of the metabolites for all soils (R2 > 0.98; 1/n ~ 1. Sorption order (Kf was ITI > ICA > FDAT. Mean values of Kf,oc were 453, 289, and 81 (BRA and 444, 48, and 48 (USA for metabolites ITI, ICA, and FDAT respectively. Desorption was hysteretic for all metabolites in all soils. These results suggest that these metabolites fall in the classification range of mobile to moderately mobile in soils.

Depressive realism and the effect of intertrial interval on judgements of zero, positive, and negative contingencies.

Science.gov (United States)

Msetfi, Rachel M; Murphy, Robin A; Simpson, Jane

2007-03-01

In three experiments we tested how the spacing of trials during acquisition of zero, positive, and negative response-outcome contingencies differentially affected depressed and nondepressed students' judgements. Experiment 1 found that nondepressed participants' judgements of zero contingencies increased with longer intertrial intervals (ITIs) but not simply longer procedure durations. Depressed groups' judgements were not sensitive to either manipulation, producing an effect known as depressive realism only with long ITIs. Experiments 2 and 3 tested predictions of Cheng's (1997) Power PC theory and the Rescorla-Wagner (1972) model, that the increase in context exposure experienced during the ITI might influence judgements most with negative contingencies and least with positive contingencies. Results suggested that depressed people were less sensitive to differences in contingency and contextual exposure. We propose that a context-processing difference between depressed and nondepressed people removes any objective notion of "realism" that was originally employed to explain the depressive realism effect (Alloy & Abramson, 1979).

Developmental Pathways for Social Understanding: Linking Social Cognition to Social Contexts

Directory of Open Access Journals (Sweden)

Kimberly eBrink

2015-05-01

Full Text Available Contemporary research, often with looking-time tasks, reveals that infants possess foundational understandings of their social worlds. However, few studies have examined how these early social cognitions relate to the child’s social interactions and behavior in early development. Does an early understanding of the social world relate to how an infant interacts with his or her parents? Do early social interactions along with social-cognitive understandings in infancy predict later preschool social competencies? In the current paper, we propose a theory in which children’s later social behaviors and their understanding of the social world depend on the integration of early social understanding and experiences in infancy. We review several of our studies, as well as other research, that directly examine the pathways between these competencies to support a hypothesized network of relations between social-cognitive development and social-interactive behaviors in the development from infancy to childhood. In total, these findings reveal differences in infant social competences that both track the developmental trajectory of infants’ understanding of people over the first years of life and provide external validation for the large body of social-cognitive findings emerging from laboratory looking-time paradigms.

2016-01-01

This study was conducted to evaluate the efficacy of oral administration of fenbendazole (20 mg/kg body weight) prior to and after experimental infection of immunosuppressed rabbits with Encephalitozoon cuniculi . A total of thirty rabbits were divided into five groups: NN (non-immunosuppressed; non-infected), IN (immunosuppressed; non-infected), IPI (immunosuppressed; protected-infected), ITI (immunosuppressed; treated-infected), and II (immunosuppressed; infected) groups. Fenbendazole was administered as a prophylactic for seven successive days before infection with E. cuniculi and as a treatment for four weeks initiated on the 28th day post-challenge (PC). Experimental rabbits were infected with intraperitoneal injection of 2 × 10 5 E. cuniculi spores. Parameters evaluated were body weight, detection of spores in urine, serum antibody assay, hematological, biochemical and histopathological changes. The IPI and ITI groups showed a significant better final bwt than the II group. Spores were detected in urine of all infected rabbits from the 28th day PC until the end of the study. The IPI group showed the least values of antibodies (IgG) compared to the ITI and II groups. Concerning histopathological changes, the intensity of the lesions was marked particularly in the II rabbits and to a lesser extent in the ITI rabbits. Noticeable improvement was found in the IPI rabbits. It could be concluded that fenbendazole was effective to some extent in protection of rabbits against E. cuniculi infection, while when administered as a therapeutic no significant effects were observed.

Can Designing Self-Representations through Creative Computing Promote an Incremental View of Intelligence and Enhance Creativity among At-Risk Youth?

Directory of Open Access Journals (Sweden)

Ina Blau

2016-12-01

Full Text Available Creative computing is one of the rapidly growing educational trends around the world. Previous studies have shown that creative computing can empower disadvantaged children and youth. At-risk youth tend to hold a negative view of self and perceive their abilities as inferior compared to “normative” pupils. The Implicit Theories of Intelligence approach (ITI; Dweck, 1999, 2008 suggests a way of changing beliefs regarding one’s abilities. This paper reports findings from an experiment that explores the impact of a short intervention among at-risk youth and “normative” high-school students on (1 changing ITI from being perceived as fixed (entity view of intelligence to more flexible (incremental view of intelligence and (2 the quality of digital self-representations programmed though a creative computing app. The participants were 117 Israeli youth aged 14-17, half of whom were at-risk youth. The participants were randomly assigned to the experimental and control conditions. The experimental group watched a video of a lecture regarding brain plasticity that emphasized flexibility and the potential of human intelligence to be cultivated. The control group watched a neutral lecture about brain-functioning and creativity. Following the intervention, all of the participants watched screencasts of basic training for the Scratch programming app, designed artifacts that digitally represented themselves five years later and reported their ITI. The results showed more incremental ITI in the experimental group compared to the control group and among normative students compared to at-risk youth. In contrast to the research hypothesis, the Scratch projects of the at-risk youth, especially in the experimental condition, were rated by neutral judges as being more creative, more aesthetically designed, and more clearly conveying their message. The results suggest that creative computing combined with the ITI intervention is a way of developing

[Social medicine and social engineering].

Science.gov (United States)

Qvarsell, R

1995-01-01

In a rather complicated process starting at the middle of the 19th century and ending hundred years later social medicine was established as a science. Different theories on the social origin of the diseases and even different perspectives on the role of medicine in society did influence and shape the new discipline. The tradition from Rudolf Virchow and Alfred Grotjahn emphasizing the importance of the social causes of the diseases and the tradition from social hygiene with its stress on the hereditarian background of many diseases was mixed together in the early history of social medicine. Many of those trying to establish the new discipline thought that it could be used in order to prevent the spreading of diseases in society and also hinder the development of social maladjustments of different kinds, as for instance criminality and vagrancy. The political framework of social medicine was very much related to what in the Swedish debate later on was to be called social engineering. Both within the tradition of social liberalism and the social democratic party the ideals of a rational society governed by experts was very influential in the period between the two world wars. Some of the advocates for social medicine did even try to formulate a political programme with the new science as a base. The most influential of those was the forensic pspychiatrist Olof Kinberg (1873-1960). In a series of books and articles during the first half of the 19th century Kinberg developed a theory of a society governed by doctors educated within this new branch of science. He thought that almost every kind of social problem could be handled by these experts. Social maladjustment, criminality and even car accidents could be reduced to a minimum if only the new knowledge of the biological and medical causes of human behavior was allowed to influence the social and political organization of the society. Especially during the 1930s some politicians and also social scientists thought

Full Text Available Social cognition consists of several skills which allow us to interact with other humans. These skills include social stimuli processing, drawing inferences about others' mental states, and engaging in social interactions. In recent years, there has been growing evidence of social cognitive impairments in patients with schizophrenia. Apparently, these impairments are separable from general neurocognitive impairments, such as attention, memory and executive functioning. Moreover, social cognition seems to be a main determinant of functional outcome and could be used as a guide to elaborate new pharmacological and psychological treatments. However, most of these studies focus on individual mechanisms and observational perspectives; only few of them study schizophrenic patients during interactive situations. We first review evidences of social cognitive impairments both in social stimuli processing and in mental state attribution. We focus on the relationship between these functions and both general cognitive impairments and functional outcome. We next review recent game theory approaches to the study of how social engagement occurs in schizophrenic patients. The advantage of using game theory is that game-oriented tasks can assess social decision-making in an interactive everyday situation model. Finally, we review proposed theoretical models used to explain social alterations and their underlying biological mechanisms. Based on interactive studies, we propose a framework which takes into account the dynamic nature of social processes. Thus, understanding social skills as a result of dynamical systems could facilitate the development of both basic research and clinical applications oriented to psychiatric populations.

Social Entrepreneurship and Social Entreprises

Fernandez-Ruiz, Juan; Wang, Jin; Aigner, Thomas G.; Mishkin, Mortimer

2001-01-01

Visual habit formation in monkeys, assessed by concurrent visual discrimination learning with 24-h intertrial intervals (ITI), was found earlier to be impaired by removal of the inferior temporal visual area (TE) but not by removal of either the medial temporal lobe or inferior prefrontal convexity, two of TE's major projection targets. To assess the role in this form of learning of another pair of structures to which TE projects, namely the rostral portion of the tail of the caudate nucleus and the overlying ventrocaudal putamen, we injected a neurotoxin into this neostriatal region of several monkeys and tested them on the 24-h ITI task as well as on a test of visual recognition memory. Compared with unoperated monkeys, the experimental animals were unaffected on the recognition test but showed an impairment on the 24-h ITI task that was highly correlated with the extent of their neostriatal damage. The findings suggest that TE and its projection areas in the ventrocaudal neostriatum form part of a circuit that selectively mediates visual habit formation. PMID:11274442

Research has shown a strong pilot preference for predictive information of aircraft system status in the flight deck. However, changes in pilot behavior associated with using this predictive information have not been ascertained. The study described here quantified these changes using three types of predictive information (none, whether a parameter was changing abnormally, and the time for a parameter to reach an alert range) and three initial time intervals until a parameter alert range was reached (ITIs) (1 minute, 5 minutes, and 15 minutes). With predictive information, subjects accomplished most of their tasks before an alert occurred. Subjects organized the time they did their tasks by locus-of-control with no predictive information and for the 1-minute ITI, and by aviatenavigate-communicate for the time for a parameter to reach an alert range and the 15-minute conditions. Overall, predictive information and the longer ITIs moved subjects to performing tasks before the alert actually occurred and had them more mission oriented as indicated by their tasks grouping of aviate-navigate-communicate.

2015-09-01

The present study aimed to investigate how online and offline social behavior interact with each other ultimately to affect the well-being of socially anxious adolescents. Based on previous studies, it was assumed that there might be three-way interactive effects among online social behavior, offline social behavior, and social anxiety regarding the relationship with well-being. To measure social anxiety, online and offline social behavior, and mental well-being, self-report questionnaires such as the Korean-Social Avoidance and Distress Scale, Korean version of the Relational Maintenance Behavior Questionnaire, and Korean version of Mental Health Continuum Short Form were administered to 656 Korean adolescents. Hierarchical regression analysis revealed that the three-way interaction of online social behavior, offline social behavior, and social anxiety was indeed significant. First, online social behavior was associated with lower well-being of adolescents with higher social anxiety under conditions of low engagement in offline social behavior. In contrast, a higher level of online social behavior predicted greater well-being for individuals with high social anxiety under conditions of more engagement in offline social behavior. Second, online social behavior was not significantly related to well-being in youths with low social anxiety under conditions of both high and low engagement in offline social behavior. Implications and limitations of this study were discussed.

Social in, social out: How the brain responds to social language with more social language.

Science.gov (United States)

O'Donnell, Matthew Brook; Falk, Emily B; Lieberman, Matthew D

Social connection is a fundamental human need. As such, people's brains are sensitized to social cues, such as those carried by language, and to promoting social communication. The neural mechanisms of certain key building blocks in this process, such as receptivity to and reproduction of social language, however, are not known. We combined quantitative linguistic analysis and neuroimaging to connect neural activity in brain regions used to simulate the mental states of others with exposure to, and re-transmission of, social language. Our results link findings on successful idea transmission from communication science, sociolinguistics and cognitive neuroscience to prospectively predict the degree of social language that participants utilize when re-transmitting ideas as a function of 1) initial language inputs and 2) neural activity during idea exposure.

Full Text Available Objective: The purpose of the study is to report and to analyze the complications following intratympanic injections (ITI of steroids. The occurrence rate of complications at different ITI sites, four quadrants of eardrum, was also compared. Methods: A retrospective clinical review in a medical center. Each patient received ITI twice in a week for 2–3 consecutive weeks as a salvage therapy for sudden sensorineural hearing loss. Post-injection complications, especially transient dizziness and vertigo, were recorded. Patients with acute or chronic vertigo episodes in 1 month were excluded. Results: A total of 59 patients with sudden sensorineural hearing loss and a total of 278 times of ITI were performed in 1 year. The post-injection complications included pain, tongue numbness, transient dizziness, vertigo, tinnitus, and a small persistent perforation. There was no significant difference in the occurrence of these complications between the injections sites on the 4 quadrants of the tympanic membrane. However, there was statistical significance in the post-injection vertiginous episode after IT injections to posterior-inferior quadrant (Q3 and posterior-superior quadrant (Q4 compared to anterior-superior quadrant (Q1 and anterior-inferior quadrant (Q2 (P = 0.0113. Conclusion: IT injection is recommended to be applied to the Q2 since the Q1 and Q4 injections are more likely to induce the adverse effect of tongue numbness, while the Q3 and Q4 areas are more likely to induce post-injection vertigo.

Social dialogue and social conflict as a topical factors of social transformations

2015-01-01

Full Text Available The critical state of society can be measured by a system of interrelated indicators - economic, technologi­cal, political, cultural, ethnic and demographic. However, it is no exaggeration to state that they originally focused on the social aspects of life people lead to an integrated life crisis at a time of social transformations. There is no universal model of social dialogue; it is a means of improving productivity and competitiveness. Social dialogue - not only a form of crisis management, sometimes governments are turning to social part­ners only in case of economic crisis, seeking their support in taking unpopular measures. This approach is fundamentally wrong, because the dialogue is based on mutual trust and confidence, cooperation achieved over the years. That social dialogue should be used not only in adverse but also in favorable socio-economic circumstances. Opposition, competition, conflict, alternative, dissent is not only inevitable characteristics of a complex human world, but necessary factors that discourage stagnation, stagnation of society, the condi­tions of its constant renewal and development. Clarification of the nature and essence of social conflict as a specific manifestation of the contradictions of social relations requires consideration of a number of interre­© І.З. Держко, 2015 lated factors. First of all, we should take into account the fact that modern society is the very course of change in scientific thinking, social structure, is drawn into a new state, which is accompanied by adapting social transformation. That is why these problems require analysis of the conditions of its emergence, development methods and tools for forecasting and warning deviation from social norms. Social process includes ways of interaction between state and society, institutions and groups, political system and social environment, government and citizens.

In January, 2014, the division "Social Medicine in Practice and Rehabilitation" of the German Society for Social Medicine and Prevention established a working group on the self-image of the physicians active in the field of social medicine (medical expertise and counseling). The result of this work is the contribution presented here after consensus was achieved by specialists of social medicine from different fields and institutions (social security etc.) and in good cooperation with Prof. Dr. Gostomzyk and Prof. Dr. Robra. Based on the importance of an up to date social medicine for claimants and recipients of benefits on the one hand and the social security system on the other, and also on a description of the subjects, objectives and methods the following aspects are presented: · The perspective of social medicine. · Qualification in social medicine, concerning specialist training and continuing medical education. · The fields of duty of experts in social medicine. · The proceedings in social medicine. The working group identified challenges for the specialists in social medicine by a narrowed perception of social medicine by physicians in hospitals and practice, accompanied by an enlarged importance of expertise in social medicine, by the demand for more "patient orientation" and gain of transparency, and concerning the scientific foundation of social medicine. The working group postulates: · The perspective of social medicine should be spread more widely.. · Confidence in experts of social medicine and their independency should be strengthened.. · The not case-related consulting of the staff and executives should be expanded.. · Social medicine in practice needs support by politics and society, and especially by research and teaching.. · Good cooperation and transfer of experiences of the different branches of social security are essential for the impact of social medicine.. © Georg Thieme Verlag KG Stuttgart · New York.

People with psychosis are at risk of social exclusion. Research is needed in this area due to the lack of direct measurement of social inclusion, which becomes salient in adolescence and is relevant to first-episode psychosis (FEP; the onset of which typically occurs during or shortly after adolescence). Social inclusion may be impacted by impaired social cognition and social functioning, which are related features observed in psychosis. The aim of this study was to explore interrelationship(s) between social cognition, social functioning and social inclusion in FEP while controlling for symptomatology (positive, negative and depressive symptoms) and demographic characteristics. A series of cross-sectional hierarchical multiple regressions were conducted to examine whether: social cognition (theory of mind, emotion recognition) predicted social functioning; social functioning predicted social inclusion, and whether social functioning mediated the relationship between social cognition and social inclusion in people aged 15 to 25 (M = 20.49, SD = 2.41) with FEP (N = 146). Age, sex, premorbid IQ, positive and negative psychotic symptoms and depression were control variables. Poor facial emotion recognition (β = -.22, P social functioning. Role-specific social functioning (ie, current employment) predicted greater social inclusion (β = .17, P social inclusion (β = -.43, P Social functioning did not mediate the relationship between social cognition and inclusion. Psychotic symptoms were unrelated to social inclusion. Employment and depression may influence social inclusion somewhat independently of psychotic symptomatology in FEP. Inferences should be viewed with caution given this study did not involve longitudinal data. © 2017 John Wiley & Sons Australia, Ltd.

Kindergarteners' self-reported social inhibition and observed social reticence: moderation by adult-reported social inhibition and social anxiety disorder symptoms.

Prevention of later anxiety problems would best be accomplished by identifying at-risk children early in development. For example, children who develop Social Anxiety Disorder (SAD) may show social withdrawal in the form of social inhibition (i.e., shyness with unfamiliar adults and peers) at school entry. Although the use of children's perceptions of their own social inhibition would provide insight into early risk, the utility of young children's self-reports remains unclear. The current study examined whether children deemed more extreme on social inhibition or social anxiety by adult report provided self-report of social inhibition that related to observed social reticence in the laboratory. Participants included 85 kindergarten children (36 female, 49 male), their parents, and their teachers. Moderation analyses revealed that children's self-reported social inhibition related significantly to observed social reticence under the conditions of high parent-reported social inhibition, high teacher-reported social inhibition, and high SAD symptoms. These results suggest that the most inhibited children are aware of their behavior and can report it in a meaningfully way as young as kindergarten age.

Social Moments: A Perspective on Interaction for Social Robotics

Directory of Open Access Journals (Sweden)

Gautier Durantin

2017-06-01

Full Text Available During a social interaction, events that happen at different timescales can indicate social meanings. In order to socially engage with humans, robots will need to be able to comprehend and manipulate the social meanings that are associated with these events. We define social moments as events that occur within a social interaction and which can signify a pragmatic or semantic meaning. A challenge for social robots is recognizing social moments that occur on short timescales, which can be on the order of 102 ms. In this perspective, we propose that understanding the range and roles of social moments in a social interaction and implementing social micro-abilities—the abilities required to engage in a timely manner through social moments—is a key challenge for the field of human robot interaction (HRI to enable effective social interactions and social robots. In particular, it is an open question how social moments can acquire their associated meanings. Practically, the implementation of these social micro-abilities presents engineering challenges for the fields of HRI and social robotics, including performing processing of sensors and using actuators to meet fast timescales. We present a key challenge of social moments as integration of social stimuli across multiple timescales and modalities. We present the neural basis for human comprehension of social moments and review current literature related to social moments and social micro-abilities. We discuss the requirements for social micro-abilities, how these abilities can enable more natural social robots, and how to address the engineering challenges associated with social moments.

Integrating social networks and human social motives to achieve social influence at scale

Contractor, Noshir S.; DeChurch, Leslie A.

2014-01-01

The innovations of science often point to ideas and behaviors that must spread and take root in communities to have impact. Ideas, practices, and behaviors need to go from accepted truths on the part of a few scientists to commonplace beliefs and norms in the minds of the many. Moving from scientific discoveries to public good requires social influence. We introduce a structured influence process (SIP) framework to explain how social networks (i.e., the structure of social influence) and human social motives (i.e., the process of social influence wherein one person’s attitudes and behaviors affect another’s) are used collectively to enact social influence within a community. The SIP framework advances the science of scientific communication by positing social influence events that consider both the “who” and the “how” of social influence. This framework synthesizes core ideas from two bodies of research on social influence. The first is network research on social influence structures, which identifies who are the opinion leaders and who among their network of peers shapes their attitudes and behaviors. The second is research on social influence processes in psychology, which explores how human social motives such as the need for accuracy or the need for affiliation stimulate behavior change. We illustrate the practical implications of the SIP framework by applying it to the case of reducing neonatal mortality in India. PMID:25225373

How social cognition can inform social decision making

Lee, Victoria K.; Harris, Lasana T.

2013-01-01

Social decision-making is often complex, requiring the decision-maker to make inferences of others' mental states in addition to engaging traditional decision-making processes like valuation and reward processing. A growing body of research in neuroeconomics has examined decision-making involving social and non-social stimuli to explore activity in brain regions such as the striatum and prefrontal cortex, largely ignoring the power of the social context. Perhaps more complex processes may influence decision-making in social vs. non-social contexts. Years of social psychology and social neuroscience research have documented a multitude of processes (e.g., mental state inferences, impression formation, spontaneous trait inferences) that occur upon viewing another person. These processes rely on a network of brain regions including medial prefrontal cortex (MPFC), superior temporal sulcus (STS), temporal parietal junction, and precuneus among others. Undoubtedly, these social cognition processes affect social decision-making since mental state inferences occur spontaneously and automatically. Few studies have looked at how these social inference processes affect decision-making in a social context despite the capability of these inferences to serve as predictions that can guide future decision-making. Here we review and integrate the person perception and decision-making literatures to understand how social cognition can inform the study of social decision-making in a way that is consistent with both literatures. We identify gaps in both literatures—while behavioral economics largely ignores social processes that spontaneously occur upon viewing another person, social psychology has largely failed to talk about the implications of social cognition processes in an economic decision-making context—and examine the benefits of integrating social psychological theory with behavioral economic theory.

Full Text Available Mapping and assessing social networks and the quality of their social support is a valuable intervention strategy for social workers. These networks have now spread onto the digital realm in the form of Online Social Networks (OSNs. This study investigated the nature of social support provided by such networks to their users in a rural mid-South University (USA and explored parallels with the current understanding of social support in conventional social networks. A web-based survey administered to college students revealed that users of these online networks were predominantly undergraduate first year students, female, single, unemployed and from a variety of academic disciplines. The examination of the components of OSNs appears to mirror those of offline networks. They also seem to complement the effects of each other while contributing to an individual's support system. The paper concludes with critical implications of such online social networking for University students and social workers in practice and education.

Full Text Available The article is aimed at defining the essence of social investment, substantiating the levels of their implementation, and identifying the mechanisms of influence on social capital. The dynamics of the level of trust in the Ukrainian society is analyzed, on the basis of which the conclusion about the crisis of complete personal and institutional distrust, as well as the necessity of systematic work on the formation of social capital, has been made. The essence of social investments as such, which are directed on development of objects of social environment, including human and social capitals, has been defined. It has been suggested to study social investment on the nano-, micro-, meso-, macro- and mega-levels. The relevant investors and beneficiaries, as well as possible directions of their activity activation, are considered. Prospect for further scientific researches should be development of mechanism for efficient interaction of international organizations, governmental structures, representatives of business and civil society as a whole with the purpose of formation of strategy of social investment, which would facilitate the implementation of structural reforms and ensure the sustainable development of Ukraine.

Full Text Available Manipulating different behavioral characteristics of gambling games can potentially affect the extent to which individuals persevere at gambling, and their transition to problematic behaviors. This has potential impact for mobile gambling technologies and responsible gambling interventions. Two laboratory models pertinent to this are the partial reinforcement extinction effect and the trial spacing effect. Both of these might speed up or delay the acquisition and extinction of conditioned behaviour. We report an experiment that manipulated the rate of reinforcement and inter trial interval (ITI on a simulated slot machine where participants were given the choice between gambling and skipping on each trial, before perseverative gambling was measured in extinction, followed by measurements of the illusion of control, depression and impulsivity. We hypothesized that longer ITI’s in conjunction with the low rates of reinforcement observed in gambling would lead to greater perseverance. We further hypothesized, given that timing is known to be important in displaying illusory control and potentially in persevering in gambling, that prior exposure to longer intervals might affect illusions of control. An interaction between ITI and rate of reinforcement was observed, as low reinforced gamblers with a long ITI gambled for longer. Respondents also displayed extinction and a partial reinforcement extinction effect. Gamblers exposed to a higher rate of reinforcement gambled for longer in acquisition. Impulsivity was associated with extended perseverance in extinction, and more depressed gamblers in the high reinforcement short ITI group persevered for longer. Performance in the contingency judgement failed to support the second hypothesis: the only significant contrast observed was that participants became better calibrated as the task progressed.

Social Media Analyses for Social Measurement

Demonstrations that analyses of social media content can align with measurement from sample surveys have raised the question of whether survey research can be supplemented or even replaced with less costly and burdensome data mining of already-existing or “found” social media content. But just how trustworthy such measurement can be—say, to replace official statistics—is unknown. Survey researchers and data scientists approach key questions from starting assumptions and analytic traditions that differ on, for example, the need for representative samples drawn from frames that fully cover the population. New conversations between these scholarly communities are needed to understand the potential points of alignment and non-alignment. Across these approaches, there are major differences in (a) how participants (survey respondents and social media posters) understand the activity they are engaged in; (b) the nature of the data produced by survey responses and social media posts, and the inferences that are legitimate given the data; and (c) practical and ethical considerations surrounding the use of the data. Estimates are likely to align to differing degrees depending on the research topic and the populations under consideration, the particular features of the surveys and social media sites involved, and the analytic techniques for extracting opinions and experiences from social media. Traditional population coverage may not be required for social media content to effectively predict social phenomena to the extent that social media content distills or summarizes broader conversations that are also measured by surveys.

2015-04-01

The aim of this study was to investigate the association between intermediary social determinants, namely social support and social network with dental caries in adolescents. An adapted version of the WHO social determinants of health conceptual framework was used to organize structural and intermediary social determinants of dental caries into six blocks including perceived social support and number of social networks. A cross-sectional study was conducted with a representative sample of 542 students between 12 and 14 years of age in public schools located in the city of Dourados, Brazil in 2012. The outcome variables were caries experience (DMFT ≥ 1) and current dental caries (component D of DMFT ≥ 1) recorded by a calibrated dentist. Individual interviews were performed to collect data on perceived social support and numbers of social networks from family and friends and covariates. Multivariate Poisson regressions using hierarchical models were conducted. The prevalence of adolescents with caries experience and current dental caries was 55.2% and 32.1%, respectively. Adolescents with low numbers of social networks and low levels of social support from family (PR 1.47; 95% CI = 1.01-2.14) were more likely to have DMFT ≥ 1. Current dental caries was associated with low numbers of social networks and low levels of social support from family (PR 2.26; 95% CI = 1.15-4.44). Social support and social network were influential psychosocial factors to dental caries in adolescents. This finding requires confirmation in other countries but potentially has implications for programmes to promote oral health. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

How Social Cognition Can Inform Social Decision Making

Victoria eLee

2013-12-01

Full Text Available Social decision-making is often complex, requiring the decision-maker to make inferences of others’ mental states in addition to engaging traditional decision-making processes like valuation and reward processing. A growing body of research in neuroeconomics has examined decision- making involving social and nonsocial stimuli to explore activity in brain regions such as the striatum and prefrontal cortex, largely ignoring the power of the social context. Perhaps more complex processes may influence decision-making in social versus nonsocial contexts. Years of social psychology and social neuroscience research have documented a multitude of processes (e.g. mental state inferences, impression formation, spontaneous trait inferences that occur upon viewing another person. These processes rely on a network of brain regions including medial prefrontal cortex, superior temporal sulcus, temporal parietal junction, and precuneus among others. Undoubtedly, these social cognition processes affect social decision-making since mental state inferences occur spontaneously and automatically. Few studies have looked at how these social inference processes affect decision-making in a social context despite the capability of these inferences to serve as predictions that can guide future decision-making. Here we review and integrate the person perception and decision-making literatures to understand how social cognition can inform the study of social decision-making in a way that is consistent with both literatures. We identify gaps in both literatures—while behavioral economics largely ignores social processes that spontaneously occur upon viewing another person, social psychology has largely failed to talk about the implications of social cognition processes in an economic decision-making context—and examine the benefits of integrating social psychological theory with behavioral economic theory.

Full Text Available In recent years, an increasing number of scholars and practitioners have becomeinterested in the concepts of Corporate Reputation (CR and Corporate SocialResponsibility (CSR, examining them fromdifferent perspectives using severalapproaches.Some studies of the banking industry have emphasised the benefits ofpositive CR in achieving competitive advantages.Other studies have investigated the concept of CSR in the banking sector, exploring above all how CSR impactseconomic, financial and non-financial performance and focusing on the adoptionand disclosure of such initiatives (Callado-Munoz and Utrero-Gonzales,2011:755. However, this line ofinquiry is incomplete.In recent years, a growing number ofstudies have explored the relationshipbetween CR and CSR in non-financial sectors, but few studies have investigatedthe relationship in the banking industry. Although academic researches frequentlyconclude that CSR is an important reputational driver, Baldarelli and Gigli (2011point out that there is a lack of theoryand empirical evidence regarding the linkbetween CR and CSR, highlighting the need for further analysis. The academicdebate has so far failed to answer how responsibility and reputation interact.In the case of the banking industry, where there is no well-established tradition ofinvestigating either reputation or CSR, itis even more important to clarify therelationship between these two concepts. This may give rise to useful insightswith implications for management. Thisstudy aims to contribute to a betterunderstanding of the complex debate on these issues by developing an in-depthanalysis of the extant banking literature. Thus, our literature review has thefollowing aims: a to investigate the links between CR and CSR in the bankingindustry; b to critically explore thecharacteristics and methodologies of theprimary reputational and CSR measures; andc to suggest an agenda for futureresearch.The paper is structured as follows: the next section

What Determines the Response: Test or Reference?

The stability of sensory memory has been studied by presenting a reference stimulus, a delay, and a test stimulus. As has been pointed out by Lages and Treisman (1998 Vision Research 38 557-572), the usual measure of performance depends only on the effect of test variations on the responses. The Weber fraction characterizing performance is more properly called the test stimulus Weber fraction. We measure the relative contribution of the test and reference to the response by the ratio of the test Weber fraction to the reference Weber fraction. The stimuli were two dark lines on a bright background. Seven reference separations, varying from 9.5 to 16.7 arc min, were intermixed in each run. Interstimulus intervals (ISI) of 50, 200 and 2000 msec and intertrial intervals (ITI) of 500 and 2500 msec were investigated. When the ISI was short (50 or 200 msec), for both ITIs, responses were determined equally by the test and reference. For the long ISI (2000 msec), the reference stimulus contributed less. However, only for the 500 msec ITI (and not for all observers) was the contribution of the reference stimulus negligible, as Treisman's criterion setting theory might suggest.

Models of cognitive processing in anxiety disorders state that socially anxious children display several distorted cognitive processes that maintain their anxiety. The present study investigated the role of social threat thoughts and social skills perception in relation to childhood trait and state social anxiety. In total, 141 children varying in their levels of social anxiety performed a short speech task in front of a camera and filled out self-reports about their trait social anxiety, state anxiety, social skills perception and social threat thoughts. Results showed that social threat thoughts mediated the relationship between trait social anxiety and state anxiety after the speech task, even when controlling for baseline state anxiety. Furthermore, we found that children with higher trait anxiety and more social threat thoughts had a lower perception of their social skills, but did not display a social skills deficit. These results provide evidence for the applicability of the cognitive social anxiety model to children.

What is social about social perception research?

Directory of Open Access Journals (Sweden)

Christoph eTeufel

2013-01-01

Full Text Available A growing consensus in social cognitive neuroscience holds that large portions of the primate visual brain are dedicated to the processing of social information, i.e., to those aspects of stimuli that are usually encountered in social interactions such as others’ facial expressions, actions and symbols. Yet, studies of social perception have mostly employed simple pictorial representations of conspecifics. These stimuli are social only in the restricted sense that they physically resemble objects with which the observer would typically interact. In an equally important sense, however, these stimuli might be regarded as ‘non-social’: the observer knows that they are viewing pictures and might therefore not attribute current mental states to the stimuli or might do so in a qualitatively different way than in a real social interaction. Recent studies have demonstrated the importance of such higher-order conceptualisation of the stimulus for social perceptual processing. Here, we assess the similarity between the various types of stimuli used in the laboratory and object classes encountered in real social interactions. We distinguish two different levels at which experimental stimuli can match social stimuli as encountered in everyday social settings: (i the extent to which a stimulus’ physical properties resemble those typically encountered in social interactions and (ii the higher-level conceptualisation of the stimulus as indicating another person’s mental states. We illustrate the significance of this distinction for social perception research and report new empirical evidence further highlighting the importance of mental state attribution for perceptual processing. Finally, we discuss the potential of this approach to inform studies of clinical conditions such as autism.

Full Text Available This research study analyzed the structure of educators’ implicit theoriesof intelligence (ITI and explored the relationship between ITI and beliefsabout the identification of gifted students. This study included a sampleof 372 educators. School Teachers and professors from colleges of educationfavor practical, analytical, and creative attributes in their prototypesof an intelligence person. However, participants were fairly neutral aboutwhether interpersonal and intrapersonal attributes characterized intelligentpeople. Educators that rated creativity as an important attribute ofintelligence tend to favor multiple methods to identify gifted students. Incontrast, educators who supported the use of IQ test as the primary basisof gifted identification tended to agree that analytical abilities were part ofthe structure of intelligence.

In this paper, we investigate the influence of the writing and reading intertrack interferences (ITIs) in terms of bit aspect ratio (BAR) in shingled magnetic recording by computer simulation using a read/write model which consists of a writing process based on Stoner-Wohlfarth switching asteroid by a one-side shielded isosceles triangular write head and a reading process by an around shielded read head for a discrete Voronoi medium model. The results show that BAR should be 3 to reduce the influence of writing and reading ITIs, media noise, and additive white Gaussian noise in an assumed areal density of 4.61Tbpsi.

This article examines the applicability of marketing concepts to social causes and social change. Social marketing is defined as the design, implementation, and control of programs calculated to influence the acceptability of social ideas and involving considerations of product planning, pricing, communication, distribution and marketing research. Wiebe examined four social advertising campaigns and concluded that their effectiveness depended on the presence of adequate force, direction, adequate and compatible social mechanism, and distance (the "cost" of the new attitude as seen by message's message"s recepient). A marketing planning approach is not a guarantee for the achievement of social objectives; yet, it represents a bridging mechanism linking the knowledge of the behavioral scientist with the socially useful implementation of that knowledge.

Social Anxiety and Social Support in Romantic Relationships.

Porter, Eliora; Chambless, Dianne L

Little is known about the quality of socially anxious individuals' romantic relationships. In the present study, we examine associations between social anxiety and social support in such relationships. In Study 1, we collected self-report data on social anxiety symptoms and received, provided, and perceived social support from 343 undergraduates and their romantic partners. One year later couples were contacted to determine whether they were still in this relationship. Results indicated that men's social anxiety at Time 1 predicted higher rates of breakup at Time 2. Men's and women's perceived support, as well as men's provided support, were also significantly predictive of breakup. Social anxiety did not interact with any of the support variables to predict breakup. In Study 2, a subset of undergraduate couples with a partner high (n=27) or low (n=27) in social anxiety completed two 10-minute, lab-based, video-recorded social support tasks. Both partners rated their received or provided social support following the interaction, and trained observers also coded for support behaviors. Results showed that socially anxious individuals received less support from their partners during the interaction according to participant but not observer report. High and lower social anxiety couples did not differ in terms of the target's provision of support. Taken together, results suggest that social anxiety is associated with difficulties even in the context of established romantic relationships. Clinical implications are discussed. Copyright © 2016.

Fareri, Dominic S; Delgado, Mauricio R

2014-08-01

The rapid development of social media and social networking sites in human society within the past decade has brought about an increased focus on the value of social relationships and being connected with others. Research suggests that we pursue socially valued or rewarding outcomes-approval, acceptance, reciprocity-as a means toward learning about others and fulfilling social needs of forming meaningful relationships. Focusing largely on recent advances in the human neuroimaging literature, we review findings highlighting the neural circuitry and processes that underlie pursuit of valued rewarding outcomes across non-social and social domains. We additionally discuss emerging human neuroimaging evidence supporting the idea that social rewards provide a gateway to establishing relationships and forming social networks. Characterizing the link between social network, brain, and behavior can potentially identify contributing factors to maladaptive influences on decision making within social situations. © The Author(s) 2014.

Organisational Social Capital through Corporate Social Performance

Full Text Available The purpose of this study is to identify the correlation between the corporate social responsibility performance and the Organisational Social Capital. Inductively, through grounded theory, this paper uses secondary data to develop a theoretical model which presents the relationship between the following concepts: business codes, stakeholders, Corporate Social Performance (CSP and Organisational Social Capital (OSC. This study brings together two main areas of research, namely: Organisational Social Capital and business ethics. This represents a gap in the literature, to which this research will address. Three propositions are put forward and discussed using secondary data collection methods. The findings suggest that there is a strong correlation between the characteristics which improve the quality of organisation-stakeholders relationship and the effectiveness of implementing business codes and, therefore, the increasing Corporate Social Performance.

Full Text Available The purpose of this study is to identify the correlation between the corporate social responsibility performance and the Organisational Social Capital. Inductively, through grounded theory, this paper uses secondary data to develop a theoretical model which presents the relationship between the following concepts: business codes, stakeholders, Corporate Social Performance (CSP and Organisational Social Capital (OSC. This study brings together two main areas of research, namely: Organisational Social Capital and business ethics. This represents a gap in the literature, to which this research will address. Three propositions are put forward and discussed using secondary data collection methods. The findings suggest that there is a strong correlation between the characteristics which improve the quality of organisation-stakeholders relationship and the effectiveness of implementing business codes and, therefore, the increasing Corporate Social Performance. The proposed ethical framework has, at the same time, a similar effect by incrementing Organisational Social Capital, because it shares similar features with the relation between organisation-stakeholders, business codes and CSP.

One Health in social networks and social media.

Mekaru, S R; Brownstein, J S

2014-08-01

In the rapidly evolving world of social media, social networks, mobile applications and citizen science, online communities can develop organically and separately from larger or more established organisations. The One Health online community is experiencing expansion from both the bottom up and the top down. In this paper, the authors review social media's strengths and weaknesses, earlier work examining Internet resources for One Health, the current state of One Health in social media (e.g. Facebook, Twitter, YouTube) and online social networking sites (e.g. LinkedIn and ResearchGate), as well as social media in One Health-related citizen science projects. While One Health has a fairly strong presence on websites, its social media presence is more limited and has an uneven geographic distribution. In work following the Stone Mountain Meeting,the One Health Global Network Task Force Report recommended the creation of an online community of practice. Professional social networks as well as the strategic use of social media should be employed in this effort. Finally, One Health-related research projects using volunteers (citizen science) often use social media to enhance their recruitment. Including these researchers in a community of practitioners would take full advantage of their existing social media presence. In conclusion, the interactive nature of social media, combined with increasing global Internet access, provides the One Health community with opportunities to meaningfully expand their community and promote their message.

Impact of organizational socialization towards employees' social adaptation

Directory of Open Access Journals (Sweden)

Ratković-Njegovan Biljana

2014-01-01

Full Text Available The paper discusses the importance of organizational socialization as a process of gaining knowledge on the organizational success of employees' social adaptation and encouraging their social competence. Organizational socialization as a scientific discipline as well as practically oriented adjustment activity towards employees' working environment has developed methodology and tactics of socio-cognitive, behavioural and motivational encouragement of employees to the acceptance of organizational culture. It is assumed that in the process of organizational socialization, in addition to professional and organizational adaptation, the focus is on the development of employees' social competences. Although within the evaluated performance appraisal of social competence is only estimated, and also neglected in the overall assessment of employees' work performance, organizational climate for good social skills is of great importance due to the fact that enhanced social and interpersonal communication and interaction can increase operating synergies and contribute to better business results. Although social skills are an important element of human capital, they are still insufficiently recognized as a form of intangible resources that participate in the long-term value creation. The deficit in this area can lead to the problems in performance of human relations at the workplace.

Social problem solving and social performance after a group social skills intervention for childhood brain tumor survivors.

Schulte, Fiona; Vannatta, Kathryn; Barrera, Maru

2014-02-01

The aim of this study was to explore the ability of a group social skills intervention program for childhood brain tumor survivors to effect two steps of the social information processing model: social problem solving and social performance. Participants were 15 survivors (eight men and seven women) aged 7-15 years. The intervention consisted of eight 2-h weekly sessions focused on social skills including friendship making. Social problem solving, using hypothetical scenarios, was assessed during sessions 1 and 8. Social performance was observed during intervention sessions 1, 4, and 8. Compared with session 1, significant increases were found in social performance: frequency of maintaining eye contact and social conversations with peers over the course of the intervention. No significant changes in social problem solving were noted. This pilot study is the first to report improvements related to group social skills intervention at the level of observed social performance over the course of intervention. The lack of change in social problem solving suggests that survivors may possess the social knowledge required for social situations but have difficulty enacting social behaviors.

Social traits, social networks and evolutionary biology.

Science.gov (United States)

Fisher, D N; McAdam, A G

2017-12-01

The social environment is both an important agent of selection for most organisms, and an emergent property of their interactions. As an aggregation of interactions among members of a population, the social environment is a product of many sets of relationships and so can be represented as a network or matrix. Social network analysis in animals has focused on why these networks possess the structure they do, and whether individuals' network traits, representing some aspect of their social phenotype, relate to their fitness. Meanwhile, quantitative geneticists have demonstrated that traits expressed in a social context can depend on the phenotypes and genotypes of interacting partners, leading to influences of the social environment on the traits and fitness of individuals and the evolutionary trajectories of populations. Therefore, both fields are investigating similar topics, yet have arrived at these points relatively independently. We review how these approaches are diverged, and yet how they retain clear parallelism and so strong potential for complementarity. This demonstrates that, despite separate bodies of theory, advances in one might inform the other. Techniques in network analysis for quantifying social phenotypes, and for identifying community structure, should be useful for those studying the relationship between individual behaviour and group-level phenotypes. Entering social association matrices into quantitative genetic models may also reduce bias in heritability estimates, and allow the estimation of the influence of social connectedness on trait expression. Current methods for measuring natural selection in a social context explicitly account for the fact that a trait is not necessarily the property of a single individual, something the network approaches have not yet considered when relating network metrics to individual fitness. Harnessing evolutionary models that consider traits affected by genes in other individuals (i.e. indirect genetic

Social support for schoolchildren at risk of social exclusion

2012-10-01

Full Text Available Social exclusion is a wider concept than poverty and includes not only material conditions but also inability to participate in economic, social, political and cultural life. The essence of social exclusion is social relationships (more exactly breaking off relationships, which may mean not only pushing away some members of the society, but also breaking off relationships with the society from the side of a person himself/herself. The reasons of origin of social exclusion may be legal, political, economical, social and cultural. Nowadays social exclusion is predetermined by social-economic factors. According to Poviliūnas (2001, the problems of children’s social exclusion may be solved ensuring proper education, care of public health, safety and minimal life standard. Growing aggression and violence of schoolchildren and their social exclusion are nowadays an important issue of political debate and media reports. Often schoolchildren face the risk of social exclusion at school during the period of adolescence. The risk also depends on the social status of their family in the society and the relationship of the family members. The aim of the article is to identify characteristic features of schoolchildren at risk of social exclusion and analyze social support provided for them. A quantitative research was carried out to achieve the aim. The method of data collection is a questionnaire. 105 teachers working in 3 secondary schools in Lithuania participated in the research. The research results revealed that most often schoolchildren face the risk of social exclusion at school during adolescence period. They are characterized as incommunicative, unsociable, passive, and shy, do not trust others, are vulnerable, have learning problems and avoid collaborative activities. These schoolchildren usually come from families of social risk or single parent families. The support provided at school by teachers to schoolchildren at risk of social exclusion

Social networks, social support and psychiatric symptoms: social determinants and associations within a multicultural community population.

Smyth, Natasha; Siriwardhana, Chesmal; Hotopf, Matthew; Hatch, Stephani L

2015-07-01

Little is known about how social networks and social support are distributed within diverse communities and how different types of each are associated with a range of psychiatric symptoms. This study aims to address such shortcomings by: (1) describing the demographic and socioeconomic characteristics of social networks and social support in a multicultural population and (2) examining how each is associated with multiple mental health outcomes. Data is drawn from the South East London Community Health Study; a cross-sectional study of 1,698 adults conducted between 2008 and 2010. The findings demonstrate variation in social networks and social support by socio-demographic factors. Ethnic minority groups reported larger family networks but less perceived instrumental support. Older individuals and migrant groups reported lower levels of particular network and support types. Individuals from lower socioeconomic groups tended to report less social networks and support across the indicators measured. Perceived emotional and instrumental support, family and friend network size emerged as protective factors for common mental disorder, personality dysfunction and psychotic experiences. In contrast, both social networks and social support appear less relevant for hazardous alcohol use. The findings both confirm established knowledge that social networks and social support exert differential effects on mental health and furthermore suggest that the particular type of social support may be important. In contrast, different types of social network appear to impact upon poor mental health in a more uniform way. Future psychosocial strategies promoting mental health should consider which social groups are vulnerable to reduced social networks and poor social support and which diagnostic groups may benefit most.

Individual Social Capital and Its Measurement in Social Surveys

Directory of Open Access Journals (Sweden)

Keming Yang

2007-01-01

Full Text Available With its popularity has come an unresolved issue about social capital: is it an individual or a collective property, or both? Many researchers take it for granted that social capital is collective, but most social surveys implicitly measure social capital at the individual level. After reviewing the definitions by Bourdieu, Coleman, and Putnam, I become to agree with Portes that social capital can be an individual asset and should be firstly analyzed as such; if social capital is to be analyzed as a collective property, then the analysis should explicitly draw on a clear definition of individual social capital. I thus define individual social capital as the features of social groups or networks that each individual member can access and use for obtaining further benefits. Four types of features are identified (basic, specific, generalized, and structural, and example formulations of survey questions are proposed. Following this approach, I then assess some survey questions organized under five themes commonly found in social surveys for measuring social capital: participation in organizations, social networks, trust, civic participation, and perceptions of local area. I conclude that most of these themes and questions only weakly or indirectly measure individual social capital; therefore, they should be strengthened with the conceptual framework proposed in this paper and complemented with the items used in independent surveys on social networks.

Social contract and social integration in adolescent development.

Science.gov (United States)

Hilles, W S; Kahle, L R

1985-10-01

Eighty-nine subjects from two high schools were tested during the spring of their sophomore and senior years, when their mean ages were 16 years, 1 month, and 18 years, 1 month, respectively. Composites measured social contract with: (a) independence, (b) implicit social contract, societal norms and expectations, and (c) explicit social contracts, rules. Composites and single items measured social integration with: (d) role commitment, (e) social-American Dream, accepting the belief in the American Dream that hard work would lead to social success, (f) self-American Dream, belief that hard work will produce personal satisfaction and success, (g) raw deal, perceptions of being treated unfairly, (h) self-blame, and (i) feelings of hopelessness. The results of the cross-lagged panel correlations generally support the hypothesis that students respond to implicit social contracts through role commitment, which is further expressed by a belief in the American Dream for social fulfillment, while responding to the perception of explicit social contracts by not believing in the benefits of the American Dream for personal fulfillment. These results were interpreted as supporting Dienstbier's theory of moral development.

This article offers a primer on social power and social class with respect to their theoretical importance, conceptual distinction, and empirical relationship. We introduce and define the constructs of social power, social class, and one's psychological sense of power. We next explore the complex relationship between social power and social class. Because social class can produce a sense of power within an individual, studies on social power can inform theory and research on social class. We conclude with a discussion of the current challenges and future opportunities for the study of social power and social class. Copyright © 2017 Elsevier Ltd. All rights reserved.

Halls, Georgia; Cooper, Peter J; Creswell, Cathy

2015-02-01

Social communication deficits are prevalent amongst children with anxiety disorders; however whether they are over-represented specifically among children with Social Anxiety Disorder has not been examined. This study set out to examine social communication deficits among children with Social Anxiety Disorder in comparison to children with other forms of anxiety disorder. Parents of 404 children with a diagnosed anxiety disorder completed the Social Communication Questionnaire (SCQ; Rutter, M., Bailey, A., Lord, C., 2003. The Social Communication Questionnaire - Manual. Western Psychological Services, Los Angeles, CA). Children with a diagnosis of Social Anxiety Disorder (n=262) and anxious children without Social Anxiety Disorder (n=142) were compared on SCQ total and subscale scores and the frequency of participants scoring above clinical cut-offs. Children with Social Anxiety Disorder scored significantly higher than anxious children without Social Anxiety Disorder on the SCQ total (t(352)=4.85, p<.001, d=.55, r=.27), Reciprocal Social Interaction (t(351)=4.73, p<.001, d=.55, r=.27), communication (t(344)=3.62, p<.001, d=.43, r=.21) and repetitive, restrictive and stereotyped behaviors subscales (t(353)=3.15, p=.002, d=.37, r=.18). Furthermore, children with Social Anxiety Disorder were three times more likely to score above clinical cut-offs. The participants were a relatively affluent group of predominantly non-minority status. The social communication difficulties measure relied on parental report which could be influenced by extraneous factors. Treatments for Social Anxiety Disorder may benefit from a specific focus on developing social communication skills. Future research using objective assessments of underlying social communication skills is required. Copyright © 2014 The Authors. Published by Elsevier B.V. All rights reserved.

Self-verification and social anxiety: preference for negative social feedback and low social self-esteem.

Science.gov (United States)

Valentiner, David P; Skowronski, John J; McGrath, Patrick B; Smith, Sarah A; Renner, Kerry A

2011-10-01

A self-verification model of social anxiety views negative social self-esteem as a core feature of social anxiety. This core feature is proposed to be maintained through self-verification processes, such as by leading individuals with negative social self-esteem to prefer negative social feedback. This model is tested in two studies. In Study 1, questionnaires were administered to a college sample (N = 317). In Study 2, questionnaires were administered to anxiety disordered patients (N = 62) before and after treatment. Study 1 developed measures of preference for negative social feedback and social self-esteem, and provided evidence of their incremental validity in a college sample. Study 2 found that these two variables are not strongly related to fears of evaluation, are relatively unaffected by a treatment that targets such fears, and predict residual social anxiety following treatment. Overall, these studies provide preliminary evidence for a self-verification model of social anxiety.

Disease as a theoretical concept: the case of "HPV-itis".

Science.gov (United States)

Broadbent, Alex

2014-12-01

If there is any value in the idea that disease is something other than the mere absence of health then that value must lie in the way that diseases are classified. This paper offers further development of a view advanced previously, the Contrastive Model of Disease: it develops the account to handle asymptomatic disease (previously excluded); and in doing so it relates the model to a broadly biostatistical view of health (where before the model was neutral in the naturalism debate). The developments are prompted by considering cancers featuring viruses as prominent causes, since these appear to amount to cases where the prescriptions of the Contrastive Model could be followed, but aren't. The resulting Irrelevance Objection claims that the Contrastive Model is irrelevant to medical science and practice. The paper seeks to rebut the Irrelevance Objection. Copyright © 2014 Elsevier Ltd.

Characterizing socially avoidant and affiliative responses to social exclusion

Directory of Open Access Journals (Sweden)

Katherine Elizabeth Powers

2012-07-01

Full Text Available Humans have a fundamental need for social relationships. From an evolutionary standpoint, the drive to form social connections may have evolved as an adaptive mechanism to promote survival, as group membership afforded the benefits of shared resources and security. Thus, rejection from social groups is especially detrimental, rendering the ability to detect threats to social relationships and respond in adaptive ways critical. Previous research indicates that social exclusion alters cognition and behavior in specific ways that may initially appear contradictory. That is, although some studies have found that exclusionary social threats lead to withdrawal from the surrounding social world, other studies indicate that social exclusion motivates affiliative social behavior. Here, we review the existing evidence supporting accounts of avoidant and affiliative responses, and highlight the conditions under which both categories of responses may be simultaneously employed. Then, we review the neuroimaging research implicating specific brain regions underlying the ability to detect and adaptively respond to threats of social exclusion. Collectively, these findings are suggestive of neural system highly attuned to social context and capable of motivating flexible behavioral responses.

Full Text Available Faced with a reality characterized by unsolved social and environmental problems, it is common to observe the behavior of firms in terms of its contribution in the resolution or treatment of these problems. Many of these initiatives are examples of social innovations offering new products, processes and relationships in terms of benefiting the most disadvantaged groups in areas such as safety, health, education, environment, among others. In this sense, this documentary research examines the role of social innovation in the context of corporate social responsibility, through a review of theoretical topic of innovation, social innovation and corporate social responsibility. Also, through the filter of what can be considered social innovation, raises some examples of Venezuelan companies with socially responsible approaches moving toward maturity in a socially ethical enterprise.

Build your own social network laboratory with Social Lab: a tool for research in social media.

Garaizar, Pablo; Reips, Ulf-Dietrich

2014-06-01

Social networking has surpassed e-mail and instant messaging as the dominant form of online communication (Meeker, Devitt, & Wu, 2010). Currently, all large social networks are proprietary, making it difficult to impossible for researchers to make changes to such networks for the purpose of study design and access to user-generated data from the networks. To address this issue, the authors have developed and present Social Lab, an Internet-based free and open-source social network software system available from http://www.sociallab.es . Having full availability of navigation and communication data in Social Lab allows researchers to investigate behavior in social media on an individual and group level. Automated artificial users ("bots") are available to the researcher to simulate and stimulate social networking situations. These bots respond dynamically to situations as they unfold. The bots can easily be configured with scripts and can be used to experimentally manipulate social networking situations in Social Lab. Examples for setting up, configuring, and using Social Lab as a tool for research in social media are provided.

Social-ecological frames of the social capital in Vojvodina

Directory of Open Access Journals (Sweden)

Pušić Ljubinko

2006-01-01

Full Text Available This paper discusses the general problem of territorialization and the special problems of cultural-genetical conditions in the sociological construction of social capital. The starting base is presented by the fact that a connection between the social-ecological conditions of an environment and social capital is historical, permanent and crucial. High and continuous growing level of urbanization in Vojvodina shows the prevailing of urban society inside of which the social capital is being formed. However, in the conditions of social transition also appear controversial relations which exert influence on the creation and functioning of social capital. Social-economical structure of the urban population in Vojvodina and the governing systems of values do not necessary product also the urban way of life, which therefore exerts influence on the quality of social capital. In this paper is particularly examined a connection of the spatial mobility of the urban population, institutional channels and local conditions in the social construction of social capital.

Lever conditioned stimulus-directed autoshaping induced by saccharin-ethanol unconditioned stimulus solution: effects of ethanol concentration and trial spacing.

Science.gov (United States)

Tomie, Arthur; Festa, Eugene D; Sparta, Dennis R; Pohorecky, Larissa A

2003-05-01

Two experiments were designed to evaluate whether brief access to a saccharin-ethanol solution would function as an effective unconditioned stimulus (US) in Pavlovian-autoshaping procedures. In these experiments, the insertion of a lever conditioned stimulus (CS) was followed by the brief presentation of a sipper tube containing saccharin-ethanol US solution. Experience with this Pavlovian-autoshaping procedure engendered lever CS-directed autoshaping conditioned responses (CRs) in all rats. In Experiment 1, the concentration of ethanol [0%, 2%, 4%, 6%, or 8% (vol./vol.)] in 0.1% saccharin was systematically increased within subjects across autoshaping sessions to evaluate the relation between a rat's drinking and lever pressing. In Experiment 2, the mean intertrial interval (ITI) duration (60, 90, 120 s) was systematically increased within subjects across autoshaping sessions to evaluate the effect of ITI duration on drinking and lever pressing. A pseudoconditioning control group received lever CS randomly with respect to the saccharin-ethanol US solution. In Experiment 1, lever-press autoshaping CRs developed in all rats, and the tendency of a rat to drink an ethanol concentration was predictive of the performance of lever-press autoshaping CRs. In Experiment 2, longer ITIs induced more lever CS-directed responding, and CS-US paired procedures yielded more lever CS-directed responding than that observed in CS-US random procedures. Saccharin-ethanol is an effective US in Pavlovian-autoshaping procedures, inducing more CS-directed responding than in pseudoconditioning controls receiving CS-US random procedures. More lever CS-directed responding was observed when there was more drinking of the saccharin-ethanol US solution (Experiment 1); when the CS and US were paired, rather than random (Experiment 2); and with longer mean ITI durations (Experiment 2). This pattern of results is consistent with the hypothesis that lever CS-directed responding reflects performance

Satellite retrieval of the liquid water fraction in tropical clouds between −20 and −38 °C

Directory of Open Access Journals (Sweden)

D. L. Mitchell

2012-07-01

Full Text Available This study describes a satellite remote sensing method for directly retrieving the liquid water fraction in mixed phase clouds, and appears unique in this respect. The method uses MODIS split-window channels for retrieving the liquid fraction from cold clouds where the liquid water fraction is less than 50% of the total condensate. This makes use of the observation that clouds only containing ice exhibit effective 12-to-11 μm absorption optical thickness ratios (β_eff that are quasi-constant with retrieved cloud temperature <i>T>. This observation was made possible by using two CO₂ channels to retrieve <i>T> and then using the 12 and 11 μm channels to retrieve emissivities and β_eff. Thus for <i>T> < −40 °C, β_eff is constant, but for <i>T> > −40 °C, β_eff slowly increases due to the presence of liquid water, revealing mean liquid fractions of ~ 10% around −22 °C from tropical clouds identified as cirrus by the cloud mask. However, the uncertainties for these retrievals are large, and extensive in situ measurements are needed to refine and validate these retrievals. Such liquid levels are shown to reduce the cloud effective diameter D_e such that cloud optical thickness will increase by more than 50% for a given water path, relative to D_e corresponding to pure ice clouds. Such retrieval information is needed for validation of the cloud microphysics in climate models. Since low levels of liquid water can dominate cloud optical properties, tropical clouds between −25 and −20 °C may be susceptible to the first aerosol indirect effect.

Conditioned Subjective Responses to Socially Relevant Stimuli in Social Anxiety Disorder and Subclinical Social Anxiety.

Although enhanced fear conditioning has been implicated in the origins of social anxiety disorder (SAD), laboratory evidence in support of this association is limited. Using a paradigm employing socially relevant unconditioned stimuli, we conducted two separate studies to asses fear conditioning in individuals with SAD and non-clinical individuals with high social anxiety (subclinical social anxiety [SSA]). They were compared with age-matched and gender-matched individuals with another anxiety disorder (panic disorder with agoraphobia) and healthy controls (Study 1) and with individuals with low social anxiety (Study 2). Contrary to our expectations, in both studies, self-report measures (ratings of anxiety, unpleasantness and arousal to the conditioned stimuli) of fear conditioning failed to discriminate between SAD or SSA and the other participant groups. Our results suggest that enhanced fear conditioning does not play a major role in pathological social anxiety. We used a social conditioning paradigm to study fear conditioning in clinical and subclinical social anxiety. We found no evidence of enhanced fear conditioning in social anxiety individuals. Enhanced fear conditioning may not be a hallmark of pathological social anxiety. Copyright © 2014 John Wiley & Sons, Ltd.

Social Enterprises in Brazil: Socially Produced Knowledge Versus Social Innovation.

Directory of Open Access Journals (Sweden)

Edileusa Godói-de-Sousa

2013-04-01

Full Text Available This study investigated whether socially produced knowledge in social ventures in Brazil has promoted social innovation and local development. The research is exploratory and descriptive, and was developed in two stages. At first, the sample group was composed of 378 projects selected from the mapping of Solidarity Economic Enterprises, conducted by the National Secretary of Solidarity Economy (Secretaria Nacional de Economia Solidária. The sample was surveyed to verify the main characteristics of these enterprises. After that, interviews were conducted with key managers in a sample of 32 projects. The results indicate challenges in the long path of favoring dynamic learning, with a generation of knowledge from the collective experiences of socialization: there is a lack of joint discussion and a predominance of individualized learning actions.

Social entrepreneurship

Full Text Available Social entrepreneurship has experienced a renaissance in the world over the last decade. The business sector, pressed by the economic crisis and social responsibility imperatives, started to turn towards some of the more sustainable organisational models, which combine profit and responsible orientation. Social entrepreneurship, as a whole, is characterised by the support and assistance rendered to the community and the vulnerable social groups. Social entrepreneurs are a proof that financial success does not exclude responsible behaviour towards the social community and the environment, and that the socially beneficial target may also serve as a successful business driver. At the same time, social enterprises may be a very useful source of entrepreneurial ideas in the economies which are passing through transition, with the high unemployment rates. Filling in the gaps in offering certain social services, with simultaneous profit making and offering option for engagement of entire families, are only some of the features characteristic for the social enterprises, which could become one of the leading models of business conducted in the Serbian economy.

Neuro-cognition and social cognition elements of social functioning and social quality of life.

Previous studies have shown that deficits in social cognition mediate the association between neuro-cognition and functional outcome. Based on these findings, the current study presents an examination of the mediating role of social cognition and includes two different outcomes: social functioning assessed by objective observer and social quality of life assessed by subjective self-report. Instruments measuring different aspects of social cognition, cognitive ability, social functioning and social quality of life were administered to 131 participants who had a diagnosis of a serious mental illness. Results showed that emotion recognition and attributional bias were significant mediators such that cognitive assessment was positively related to both, which in turn, were negatively related to SQoL. While one interpretation of the data suggests that deficits in emotion recognition may serve as a possible defense mechanism, future studies should re-assess this idea. Copyright © 2017 Elsevier B.V.

Cultural Aspects in Social Anxiety and Social Anxiety Disorder

Science.gov (United States)

Hofmann, Stefan G.; Asnaani, Anu; Hinton, Devon E.

2010-01-01

To examine cultural aspects in social anxiety and social anxiety disorder (SAD), we reviewed the literature on the prevalence rates, expressions, and treatments of social anxiety/SAD as they relate to culture, race, and ethnicity. We further reviewed factors that contribute to the differences in social anxiety/SAD between different cultures, including individualism/collectivism, perception of social norms, self-construal, gender roles, and gender role identification. Our review suggests that the prevalence and expression of social anxiety/SAD depends on the particular culture. Asian cultures typically show the lowest rates, whereas Russian and US samples show the highest rates, of SAD. Taijin kyofusho is discussed as a possible culture-specific expression of social anxiety, although the empirical evidence concerning the validity of this syndrome has been mixed. It is concluded that the individual's social concerns need to be examined in the context of the person's cultural, racial, and ethnic background in order to adequately assess the degree and expression of social anxiety and social anxiety disorder. This has direct relevance for the upcoming DSM-V. PMID:21132847

2010-12-01

Can ICT, and more specifically social software, support welfare organizations in their work with marginalized young people? This was the main research question addressed in INCLUSO, a research project funded by the European Commission’s 7th Framework Programme. In this paper, the authors start by introducing the concepts of social exclusion, e-inclusion and the digital divide. They discuss the concept of social software, its use by youngsters and the potential of social software to contribute to social inclusion. The authors then report on the organizational challenges met as they guided four social welfare organizations from Austria, Belgium, Poland and the UK in their implementation of social software tools to support their interaction with marginalized young people. They identify these challenges and present tools to assist social work organizations in defining successful strategies for adopting ICT and social software within their organizations. INCLUSO: Sociale software ten behoeve van sociale inclusie van gemarginaliseerde jongeren In hoeverre kan ICT, en in het bijzonder het gebruik van sociale software, een bijdrage leveren aan de sociale inclusie van kansarme jongeren? Wat is de rol van welzijnsorganisaties in dit proces en wat zijn de voornaamste belemmeringen voor het gebruik van sociale software als middel om sociale inclusie te stimuleren? Deze vragen stonden centraal in het INCLUSOproject, een onderzoeksproject dat werd gefinancierd door de European Commission’s 7th Framework Programme. Dit artikel start met een toelichting op concepten als sociale uitsluiting, digitale inclusie en digital divide. Ook wordt ingegaan op het gebruik van social software door jongeren en de potentie ervan voor sociale inclusie. De auteurs doen vervolgens verslag van de organisatorische uitdagingen die ontstonden bij de begeleiding van vier welzijnsorganisaties, bij de implementatie van social software ten behoeve van sociale inclusie.

Evolution of individual versus social learning on social networks.

Tamura, Kohei; Kobayashi, Yutaka; Ihara, Yasuo

2015-03-06

A number of studies have investigated the roles played by individual and social learning in cultural phenomena and the relative advantages of the two learning strategies in variable environments. Because social learning involves the acquisition of behaviours from others, its utility depends on the availability of 'cultural models' exhibiting adaptive behaviours. This indicates that social networks play an essential role in the evolution of learning. However, possible effects of social structure on the evolution of learning have not been fully explored. Here, we develop a mathematical model to explore the evolutionary dynamics of learning strategies on social networks. We first derive the condition under which social learners (SLs) are selectively favoured over individual learners in a broad range of social network. We then obtain an analytical approximation of the long-term average frequency of SLs in homogeneous networks, from which we specify the condition, in terms of three relatedness measures, for social structure to facilitate the long-term evolution of social learning. Finally, we evaluate our approximation by Monte Carlo simulations in complete graphs, regular random graphs and scale-free networks. We formally show that whether social structure favours the evolution of social learning is determined by the relative magnitudes of two effects of social structure: localization in competition, by which competition between learning strategies is evaded, and localization in cultural transmission, which slows down the spread of adaptive traits. In addition, our estimates of the relatedness measures suggest that social structure disfavours the evolution of social learning when selection is weak. © 2015 The Author(s) Published by the Royal Society.

Kelly, Michelle E; Duff, Hollie; Kelly, Sara; McHugh Power, Joanna E; Brennan, Sabina; Lawlor, Brian A; Loughrey, David G

2017-12-19

Social relationships, which are contingent on access to social networks, promote engagement in social activities and provide access to social support. These social factors have been shown to positively impact health outcomes. In the current systematic review, we offer a comprehensive overview of the impact of social activities, social networks and social support on the cognitive functioning of healthy older adults (50+) and examine the differential effects of aspects of social relationships on various cognitive domains. We followed PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines, and collated data from randomised controlled trials (RCTs), genetic and observational studies. Independent variables of interest included subjective measures of social activities, social networks, and social support, and composite measures of social relationships (CMSR). The primary outcome of interest was cognitive function divided into domains of episodic memory, semantic memory, overall memory ability, working memory, verbal fluency, reasoning, attention, processing speed, visuospatial abilities, overall executive functioning and global cognition. Thirty-nine studies were included in the review; three RCTs, 34 observational studies, and two genetic studies. Evidence suggests a relationship between (1) social activity and global cognition and overall executive functioning, working memory, visuospatial abilities and processing speed but not episodic memory, verbal fluency, reasoning or attention; (2) social networks and global cognition but not episodic memory, attention or processing speed; (3) social support and global cognition and episodic memory but not attention or processing speed; and (4) CMSR and episodic memory and verbal fluency but not global cognition. The results support prior conclusions that there is an association between social relationships and cognitive function but the exact nature of this association remains unclear

Seeding Social Capital? Urban Community Gardening and Social Capital

Social Business

Maria Cristina ENACHE

2015-09-01

Full Text Available The field of social business is growing rapidly and attracting increased attention from many sectors. The term itself shows up frequently in the media, is referenced by public officials, have become common on universities. The reasons behind the popularity of social entrepreneurship are many. On the most basic level, there’s something inherently interesting and appealing about entrepreneurs and the stories of why and how they do what they do. The interest in social entrepreneurship transcends the phenomenon of popularity and fascination with people. Social entrepreneurship signals the imperative to drive social change, and it is that potential payoff, with its lasting, transformational benefit to society, that sets the field and its practitioners apart. Although the potential benefits offered by social entrepreneurship are clear to many of those promoting and funding these activities, the actual definition of what social entrepreneurs do to produce this order of magnitude return is less clear. In fact, we would argue that the definition of social entrepreneurship today is anything but clear. As a result, social entrepreneurship has become so inclusive that it now has an immense tent into which all manner of socially beneficial activities fit. In some respects this inclusiveness could be a good thing. If we can achieve a rigorous definition, then those who support social entrepreneurship can focus their resources on building and strengthening a concrete and identifiable field. Absent that discipline, proponents of social entrepreneurship run the risk of giving the skeptics an ever-expanding target to shoot at, and the cynics even more reason to discount social innovation and those who drive it.

"I Don't Know What Fun Is": Examining the Intersection of Social Capital, Social Networks, and Social Recovery.

Science.gov (United States)

Boeri, Miriam; Gardner, Megan; Gerken, Erin; Ross, Melissa; Wheeler, Jack

The purpose of this paper is to understand how people with problematic drug use access positive social capital. Social capital is defined as relations that provide valuable resources to individuals through participation in social networks. People with low socioeconomic status remain at a disadvantage for acquiring positive social capital, a component of recovery capital. The concept of social recovery emphasises the relational processes of recovery. In-depth life history data were collected from 29 individuals who used heroin, cocaine, crack, or methamphetamine for at least five years, have less than a high school education, and unstable employment and housing. Qualitative data were coded for social networks accessed throughout the life course, distinguished by bonding, bridging and linking social capital. Social networks included drug treatment programs; non-drug-using family and friends; religious/spiritual groups; workplace networks, and social clubs/activities. Bonding and/or bridging social capital were acquired through treatment, family and friends, religious/spiritual groups, workplaces, and social clubs. Linking social capital was not acquired through any social networks available, and many barriers to accessing mainstream social networks were found. This is a small study conducted in the US. A greater focus on social recovery is needed to achieve sustained recovery for individuals lacking access to and engagement in mainstream social networks. Social recovery is proposed as an analytical tool as well as for developing prevention, intervention, and treatment strategies.

Choking under social pressure: social monitoring among the lonely.

Knowles, Megan L; Lucas, Gale M; Baumeister, Roy F; Gardner, Wendi L

2015-06-01

Lonely individuals may decode social cues well but have difficulty putting such skills to use precisely when they need them--in social situations. In four studies, we examined whether lonely people choke under social pressure by asking participants to complete social sensitivity tasks framed as diagnostic of social skills or nonsocial skills. Across studies, lonely participants performed worse than nonlonely participants on social sensitivity tasks framed as tests of social aptitude, but they performed just as well or better than the nonlonely when the same tasks were framed as tests of academic aptitude. Mediational analyses in Study 3 and misattribution effects in Study 4 indicate that anxiety plays an important role in this choking effect. This research suggests that lonely individuals may not need to acquire social skills to escape loneliness; instead, they must learn to cope with performance anxiety in interpersonal interactions. © 2015 by the Society for Personality and Social Psychology, Inc.

Social Action among Social Work Practitioners: Examining the Micro-Macro Divide.

Mattocks, Nicole Olivia

2018-01-01

Social work is a profession that seeks to enhance the well-being of all people and promote social justice and social change through a range of activities, such as direct practice, community organizing, social and political action, and policy development. However, the current literature suggests that the profession's focus on social justice and social action are weakening, replaced by individualism and therapeutic interventions. This article examines data derived from a survey of 188 National Association of Social Workers members from Maryland; Virginia; and Washington, DC, to explore levels of social action participation among social workers and determine whether identifying as a macro-level practitioner would predict higher levels of social action activity compared with being a micro-level practitioner. Findings indicate that social workers in this sample engage in only a moderate level of social action behavior. In addition, identifying oneself as a mezzo- or macro-level practitioner predicts increased frequency of social action behavior. Implications include emphasizing the importance of social action in schools of social work and practice settings and adequately preparing social work professionals to engage in social action. © 2017 National Association of Social Workers.

Once hurt, twice shy: Social pain contributes to social anxiety.

Fung, Klint; Alden, Lynn E

2017-03-01

Social rejection has been consistently linked to the development of social anxiety. However, mechanisms underlying the relation have been largely unexplored, which presents an obstacle to fully understanding the origins of social anxiety and to the development of effective prevention and treatment strategies. Two studies were conducted to test the hypothesis that the emotion of social pain following rejection promotes the development of social anxiety in subsequent situations. In Study 1, undergraduate participants were exposed to 2 social situations (Cyberball) 2 days apart. Participants who were rejected in the first situation reported higher social anxiety before and during the second situation relative to those who were included. This effect was fully mediated by initial social pain intensity. In Study 2, all participants were initially rejected. Using double-blinded drug administration, participants were randomly assigned to ingest acetaminophen to alleviate the social pain from rejection, or a sugar placebo. As predicted, the acetaminophen group reported lower social anxiety before and during the second situation. Approximately half of the effect was mediated by reduction in social pain. Notably, the immediate effect of acetaminophen was specific to social pain rather than social anxiety. Results were discussed in the context of literature on the etiology of social anxiety and social pain. Future directions were suggested. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Cultural considerations in social anxiety are a rarely investigated topic although it seems likely that differences between countries in social norms may relate to the extent of social anxiety. The present study investigated individuals' personal and perceived cultural norms and their relation to social anxiety and fear of blushing. A total of 909 participants from eight countries completed vignettes describing social situations and evaluated the social acceptability of the behavior of the main actor both from their own, personal perspective as well as from a cultural viewpoint. Personal and cultural norms showed somewhat different patterns in comparison between types of countries (individualistic/collectivistic). According to reported cultural norms, collectivistic countries were more accepting toward socially reticent and withdrawn behaviors than was the case in individualistic countries. In contrast, there was no difference between individualistic and collectivistic countries on individuals' personal perspectives regarding socially withdrawn behavior. Collectivistic countries also reported greater levels of social anxiety and more fear of blushing than individualistic countries. Significant positive relations occurred between the extent to which attention-avoiding behaviors are accepted in a culture and the level of social anxiety or fear of blushing symptoms. These results provide initial evidence that social anxiety may be related to different cultural norms across countries.

Social Anthropology and Social Science History

Science.gov (United States)

2015-01-01

In the 1970s, when the social science history movement emerged in the United States, leading to the founding of the Social Science History Association, a simultaneous movement arose in which historians looked to cultural anthropology for inspiration. Although both movements involved historians turning to social sciences for theory and method, they reflected very different views of the nature of the historical enterprise. Cultural anthropology, most notably as preached by Clifford Geertz, became a means by which historians could find a theoretical basis in the social sciences for rejecting a scientific paradigm. This article examines this development while also exploring the complex ways cultural anthropology has embraced—and shunned—history in recent years. PMID:26549914

Social Support and Social Anxiety in Use and Perceptions of Online Mental Health Resources: Exploring Social Compensation and Enhancement.

Science.gov (United States)

Ruppel, Erin K; McKinley, Christopher J

2015-08-01

This study used the frameworks of social compensation and social enhancement to examine how social anxiety and social support were related to college students' (N=443) use and perceptions of online mental health resources (Web sites and online support groups). Potential interactions between social support and social anxiety were also examined. Consistent with the social compensation hypothesis, perceived usefulness of Web sites was positively associated with social support. Perceived usefulness of online support groups was positively associated with social support when participants reported average or high, but not low, social anxiety. In contrast, previous use of Web sites was consistent with the social compensation hypothesis. Participants who reported less social support were more likely to have used a Web site for a mental or emotional problem. These findings suggest that college students' use and perceptions of online mental health resources vary as a function of social support and social anxiety, and that patterns suggestive of social compensation and social enhancement depend on whether perceptions or actual use of resources are examined. Combined with the significant interaction between social support and social anxiety on perceived usefulness of online support groups, these findings highlight the potential complexity of social compensation and enhancement phenomena.

An experimental manipulation of social comparison in social anxiety.

Science.gov (United States)

Mitchell, Melissa A; Schmidt, Norman B

2014-01-01

Negative self-appraisal is thought to maintain social anxiety particularly when comparing oneself to others. Work on social comparison suggests that gender may moderate the effects of social comparison in social anxiety. Self-appraisals of the desirability of one's personality may be more important to women, whereas self-appraisal of signs of anxiety may be more important to men. Within each gender, those with high social anxiety are expected to report more negative self-appraisal when comparing themselves to someone else described as high achieving. This study is the first we are aware of that examined gender-based interactive effects after a social comparison manipulation. Participants read a bogus profile of a fellow student's adjustment to college. They were randomly assigned to read a profile suggesting that the fellow student was "high achieving" or more normative in his/her achievements. When comparing to a "high achieving" individual, men with high social anxiety reported the most negative self-appraisals of their signs of anxiety. In addition, greater social anxiety was associated with a poorer self-appraisal of personality only among men. The implications of the findings for conceptualizing the role of social comparison in social anxiety are discussed.

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.

Social rank and social cooperation: Impact of social comparison processes on cooperative decision-making.

Directory of Open Access Journals (Sweden)

Xu Gong

Full Text Available Successful navigation of our complex social world requires the capability to recognize and judge the relative status of others. Hence, social comparison processes are of great importance in our interactions, informing us of our relative standing and in turn potentially motivating our behavior. However, so far few studies have examined in detail how social comparison can influence interpersonal decision-making. One aspect of social decision-making that is of particular importance is cooperative behavior, and identifying means of maintaining and promoting cooperation in the provision of public goods is of vital interest to society. Here, we manipulated social comparison by grading performance rankings on a reaction time task, and then measured cooperative decisions via a modified Public Goods Game (PGG. Findings revealed that individuals ranked highest tended to be more cooperative as compared to those who placed in the bottom rank. Interestingly, this effect was regardless of whether the comparison group members were the subsequent players in the PGG or not, and this effect was stronger in those with higher social orientation. In summary, the present research shows how different social comparison processes (assessed via social rankings can operate in our daily interaction with others, demonstrating an important effect on cooperative behavior.

During the current conservative political climate in the United States, power has shifted increasingly from the federal government to states, a move that has implications for the achievement of social justice. Consequently, it is now necessary for social workers to engage in political activity at the state and local levels, in addition to the federal level, to promote social justice. Implications for social work policy practice, research, and education for advancing social justice within the federal system of government are explored.

Can social sustainability be built? In this paper the potentialities and challenges of the concept of social sustainability are explored based on a collaboration project between the Danish Building Research Institute, a Danish social housing association and the Green Building Council Denmark......, aiming to better integrate standards of social sustainability in the application of certification systems like DGNB. The paper relates theory on social sustainability to the ways it is used in practice, and discusses whether and how social sustainability can be measured and certified in renewal...... and construction of housing and neighbourhoods. It is put forward that a certification has to take into account the housing complex’ or neighbourhood’s relation to the surrounding city, its development over time, its flexibility towards future needs and its social organisation and operation. Further, the interplay...

Social network in patient safety: Social media visibility

Directory of Open Access Journals (Sweden)

Azucena Santillán García

2011-11-01

Full Text Available Internet social network (social media is a powerful communication tool, and its use is expanding significantly. This paper seeks to know the current state of visibility in online social networks of active citizen talking about patient safety. This is an observational cross-sectional study whose target population is the websites Facebook, Twitter and Tuenti in Spain. By three consecutive cuts social profiles were found using the searching terms “seguridad+paciente” and “safety+patient”. There were found 5 profiles on Facebook that met the search criteria, 6 on Twitter and none were found on Tuenti. It is concluded that although there is evidence of the rise of social networking, citizen network involved in patient safety appears not to be significantly represented within the social networks examined.

Sociality comes with specific cognitive skills that allow the proper processing of information about others (social recognition), as well as of information originating from others (social learning). Because sociality and social interactions can also facilitate the spread of infection among individuals the ability to recognize and avoid pathogen threat is also essential. We review here various studies primarily from the rodent literature supporting estrogenic involvement in the regulation of social recognition, social learning (socially acquired food preferences and mate choice copying) and the recognition and avoidance of infected and potentially infected individuals. We consider both genomic and rapid estrogenic effects involving estrogen receptors α and β, and G-protein coupled estrogen receptor 1, along with their interactions with neuropeptide systems in the processing of social stimuli and the regulation and expression of these various socially relevant behaviors.

Social Skills in Children Adopted from Socially-Emotionally Depriving Institutions.

Science.gov (United States)

Julian, Megan M; McCall, Robert B

This study assessed social skills in post-institutionalized (PI) children with respect to age-at-adoption, age-at-assessment, and gender. Parent ratings of social skills (Social Skills Rating System) and behavior problems (Child Behavior Checklist) were obtained for 214 children and 127 adolescents who were adopted from socially-emotionally depriving Russian institutions. Results showed that children adopted before 18 months of age have better social skills than those adopted after this age; those assessed in childhood demonstrate better social skills than those assessed in adolescence. PI females, especially later-adopted adolescents, have particularly poor social skills. Children with poor social skills tend to have higher rates of behavior problems.

Social Justice and Multiculturalism: Persistent Tensions in the History of US Social Welfare and Social Work

Directory of Open Access Journals (Sweden)

Michael Reisch

2007-03-01

Full Text Available Social justice has been a central normative component of U.S. social welfare and social work for over a century, although the meaning and implications of the term have often been ambiguous. A major source of this ambiguity lies in the conflict between universalist views of social justice and those which focus on achieving justice for specific groups. This conflict has been masked by several long-standing assumptions about the relationship between social justice and multiculturalism – assumptions which have been challenged by recent developments. The assumption that the pursuit of social justice requires the creation of a more egalitarian society has been challenged by the new political-economic realities of globalization. The assumption that the maintenance of individual rights complements the pursuit of social equality has been challenged by racially-based attacks on social welfare benefits and civil rights. Most significantly, the assumption that a socially just society is one in which different groups share a compatible vision of social justice has been challenged by the realities of multiculturalism. This paper explores the evolution of four themes regarding the relationship between social justice and multiculturalism during the past century and discusses their implications for the contemporary demographic and cultural context of the U.S. These themes are: the relationship of cultural diversity to the nation’s values and goals; the contradiction between coerced cultural assimilation and coerced physical and social segregation; the relationship between individual and group identity and rights; and the linkage between “Americanization” and the equal application of justice.

Social media is a group of Internet-based applications that allows individuals to create, collaborate, and share content with one another. Practitioners can realize social media's untapped potential by incorporating it as part of the larger social marketing strategy, beyond promotion. Social media, if used correctly, may help organizations increase their capacity for putting the consumer at the center of the social marketing process. The purpose of this article is to provide a template for strategic thinking to successfully include social media as part of the social marketing strategy by using a four-step process.

SOCIAL DISTANCES AS A FEATURE OF THE CONTEMPORARY RUSSIAN SOCIAL SPACE

Directory of Open Access Journals (Sweden)

Л А Беляева

2018-12-01

Full Text Available Social space is a theoretical construct that allows to consider many key problems of social development including the society’s consolidation. The author defines social space as a set of social statuses and distances. Their objective characteristics are interrelated with subjective indicators identified through the opinions of individuals. The balance of statuses and distances in society and the acceptability of this structure for the majority of population ensure the stability of society and effective social control. If this balance is disturbed, social tensions arise and threaten the stability and consolidation of society. Thus, the ideas of the theories of social space possess a considerable heuristic potential for revealing urgent problems of social development such as solidarity, social stratification and mobility, social networks and their interaction, connections of local communities within and with the world, interaction of structured social relations and individual and collective practices, genesis of social space as a result of social production represented by both things and relationships, etc. According to the theory of P. Bourdieu, the author con-siders social space as a structure of social statuses based on the set of different types of capital: economic, cultural, social, and symbolic. The author uses statistical data and results of the monitoring survey conducted on the all-Russian sample. The article proposes some tested empirical indicators that proved the increase of social distances in Russia due to the redistribution of economic capital and, as a consequence, of cultural and social capitals. Thus, the social space of Russia cannot be considered stable. To ensure its greater stability we need a set of measures to reduce social distances: re-industrialization to create high-tech jobs, development of digital economy, and improvement of the mass secondary and higher education system - these measures can create a basis for the

Depersonalization/derealization during acute social stress in social phobia.

Hoyer, Juergen; Braeuer, David; Crawcour, Stephen; Klumbies, Elisabeth; Kirschbaum, Clemens

2013-03-01

The present study aimed at investigating how frequently and intensely depersonalization/derealization symptoms occur during a stressful performance situation in social phobia patients vs. healthy controls, as well as testing hypotheses about the psychological predictors and consequences of such symptoms. N=54 patients with social phobia and N=34 control participants without mental disorders were examined prior to, during, and after a standardized social performance situation (Trier Social Stress Test, TSST). An adapted version of the Cambridge Depersonalization Scale was applied along with measures of social anxiety, depression, personality, participants' subjective appraisal, safety behaviours, and post-event processing. Depersonalization symptoms were more frequent in social phobia patients (92%) than in controls (52%). Specifically in patients, they were highly positively correlated with safety behaviours and post-event-processing, even after controlling for social anxiety. The role of depersonalization/derealization in the maintenance of social anxiety should be more thoroughly recognized and explored. Copyright © 2013 Elsevier Ltd. All rights reserved.

Social Capital and Walkability as Social Aspects of Sustainability

Directory of Open Access Journals (Sweden)

Shannon H. Rogers

2013-08-01

Full Text Available The concepts of sustainability and sustainable development are frequently described as having three main components, sometimes referred to as the three pillars or the triple bottom line: environmental, economic, and social. Because of an historical focus in the sustainability field on correcting environmental problems, much consideration has been given to environmental issues, especially how they interface with economic ones. Frequently mentioned but rarely examined, the social aspects of sustainability have been considered the weakest and least described pillar. After a brief review of existing concepts and theories, this paper uses a case study approach to examine the third pillar more comprehensively and offers social capital as one measure of social sustainability. Specifically, social capital was used to measure the social-environmental interface of communities. The positive correlation between aspects of the built environment, specifically walkability, and social capital suggests that measuring a social aspect of sustainability may be feasible, especially in the context of community development.

Threats to social identity can trigger social deviance.

Science.gov (United States)

Belmi, Peter; Barragan, Rodolfo Cortes; Neale, Margaret A; Cohen, Geoffrey L

2015-04-01

We hypothesized that threats to people's social (i.e., group) identity can trigger deviant attitudes and behaviors. A correlational study and five experiments showed that experiencing or recalling situations associated with the devaluation of a social identity caused participants to endorse or engage in deviant actions, including stealing, cheating, and lying. The effect was driven by the tendency to construe social identity threats not as isolated incidents but as symbolic of the continuing devaluation and disrespectful treatment of one's group. Supplementing sociological approaches to deviance and delinquency, the results suggest the relevance and utility of a social-psychological account. © 2015 by the Society for Personality and Social Psychology, Inc.

Lemieux, Robert; Lajoie, Sean; Trainor, Nathan E

2013-04-01

This study explored the relations between use of the social networking site Facebook and scores on affinity-seeking, social loneliness, and social avoidance by 313 college students. Social loneliness and social avoidance, but not affinity-seeking, were positively and statistically significantly related to time spent using Facebook. The number of close Facebook friends was negatively and statistically significantly related to social loneliness and social avoidance. Women perceived Facebook as a more integral part of daily interactions than did men. 38% of the 283 Facebook members indicated their accounts contained information and/or a picture that could embarrass them, with men having significantly more embarrassing content than women. The findings are discussed within the context of social compensation.

“I Don’t Know What Fun Is”: Examining the Intersection of Social Capital, Social Networks, and Social Recovery

Science.gov (United States)

Boeri, Miriam; Gardner, Megan; Gerken, Erin; Ross, Melissa; Wheeler, Jack

2016-01-01

Purpose The purpose of this paper is to understand how people with problematic drug use access positive social capital. Social capital is defined as relations that provide valuable resources to individuals through participation in social networks. People with low socioeconomic status remain at a disadvantage for acquiring positive social capital, a component of recovery capital. The concept of social recovery emphasises the relational processes of recovery. Design/methodology/approach In-depth life history data were collected from 29 individuals who used heroin, cocaine, crack, or methamphetamine for at least five years, have less than a high school education, and unstable employment and housing. Qualitative data were coded for social networks accessed throughout the life course, distinguished by bonding, bridging and linking social capital. Findings Social networks included drug treatment programs; non-drug-using family and friends; religious/spiritual groups; workplace networks, and social clubs/activities. Bonding and/or bridging social capital were acquired through treatment, family and friends, religious/spiritual groups, workplaces, and social clubs. Linking social capital was not acquired through any social networks available, and many barriers to accessing mainstream social networks were found. Limitations This is a small study conducted in the US. Social implications A greater focus on social recovery is needed to achieve sustained recovery for individuals lacking access to and engagement in mainstream social networks. Practical implications Social recovery is proposed as an analytical tool as well as for developing prevention, intervention, and treatment strategies. PMID:27668008

Understanding Social Contagion in Adoption Processes Using Dynamic Social Networks.

Directory of Open Access Journals (Sweden)

Mauricio Herrera

Full Text Available There are many studies in the marketing and diffusion literature of the conditions in which social contagion affects adoption processes. Yet most of these studies assume that social interactions do not change over time, even though actors in social networks exhibit different likelihoods of being influenced across the diffusion period. Rooted in physics and epidemiology theories, this study proposes a Susceptible Infectious Susceptible (SIS model to assess the role of social contagion in adoption processes, which takes changes in social dynamics over time into account. To study the adoption over a span of ten years, the authors used detailed data sets from a community of consumers and determined the importance of social contagion, as well as how the interplay of social and non-social influences from outside the community drives adoption processes. Although social contagion matters for diffusion, it is less relevant in shaping adoption when the study also includes social dynamics among members of the community. This finding is relevant for managers and entrepreneurs who trust in word-of-mouth marketing campaigns whose effect may be overestimated if marketers fail to acknowledge variations in social interactions.

to critically appraise the available literature and summarise the evidence relating to adolescent mothers' use of social networking sites in terms of any social support and social capital they may provide and to identify areas for future exploration. social networking sites have been demonstrated to provide social support to marginalised individuals and provide psycho-social benefits to members of such groups. Adolescent mothers are at risk of; social marginalisation; anxiety disorders and depressive symptoms; and poorer health and educational outcomes for their children. Social support has been shown to benefit adolescent mothers thus online mechanisms require consideration. a review of original research articles METHOD: key terms and Boolean operators identified research reports across a 20-year timeframe pertaining to the area of enquiry in: CINAHL, Cochrane Library, Medline, Scopus, ERIC, ProQuest, PsychINFO, Web of Science, Health Collection (Informit) and Google Scholar databases. Eight original research articles met the inclusion criteria for this review. studies demonstrate that adolescent mothers actively search for health information using the Internet and social networking sites, and that social support and social capital can be attributed to their use of specifically created online groups from within targeted health interventions. Use of a message board forum for pregnant and parenting adolescents also demonstrates elements of social support. There are no studies to date pertaining to adolescent mothers' use of globally accessible social networking sites in terms of social support provision and related outcomes. further investigation is warranted to explore the potential benefits of adolescent mothers' use of globally accessible social networking sites in terms of any social support provision and social capital they may provide.

Oxytocin attenuates social and non-social avoidance: Re-thinking the social specificity of Oxytocin.

Science.gov (United States)

Harari-Dahan, Osnat; Bernstein, Amit

2017-07-01

Re-examining decades of the social construal of Oxytocin, the General Approach-Avoidance Hypothesis of Oxytocin (GAAO) predicts that Oxytocin will modulate responding to emotionally-evocative and personally-relevant social and non-social stimuli due to its action on the neural substrate of approach and avoidance motivation. We report the first critical experimental test of GAAO predictions by means of a double-blind intra-nasal administration of Oxytocin vs. placebo in 90 healthy adults (N=90, 50% women). As predicted, we found that among men and women for whom negative emotion (anxious arousal) is motivationally-relevant, intra-nasal administration of Oxytocin reduced behavioral avoidance of emotionally-evocative negatively-valenced social and non-social stimuli, but not closely matched emotionally-neutral stimuli. Findings cannot be explained by extant social theories of Oxytocin. We discuss the implications of the present findings for basic and translational clinical Oxytocin research.

2015-01-01

Previous studies on social anxiety have demonstrated negative-expectancy bias in social contexts. In this study, we used a paradigm that employed self-relevant positive or negative social feedback, in order to test whether this negative expectancy manifests in event-related potentials (ERPs) during social evaluation among socially anxious individuals. Behavioral data revealed that individuals with social anxiety disorder (SAD) showed more negative expectancy of peer acceptance both in the experiment and in daily life than did the healthy control participants. Regarding ERP results, we found a overally larger P2 for positive social feedback and also a group main effect, such that the P2 was smaller in SAD group. SAD participants demonstrated a larger feedback-related negativity (FRN) to positive feedback than to negative feedback. In addition, SAD participants showed a more positive ΔFRN (ΔFRN = negative – positive). Furthermore, acceptance expectancy in daily life correlated negatively with ΔFRN amplitude, while the Interaction Anxiousness Scale (IAS) score correlated positively with the ΔFRN amplitude. Finally, the acceptance expectancy in daily life fully mediated the relationship between the IAS and ΔFRN. These results indicated that both groups could differentiate between positive and negative social feedback in the early stage of social feedback processing (reflected on the P2). However, the SAD group exhibited a larger FRN to positive social feedback than to negative social feedback, demonstrating their dysfunction in the late stage of social feedback processing. In our opinion, such dysfunction is due to their greater negative social feedback expectancy. PMID:26635659

However, the SAD group exhibited a larger FRN to positive social feedback than to negative social feedback, demonstrating their dysfunction in the late stage of social feedback processing. In our opinion, such dysfunction is due to their greater negative social feedback expectancy.

Full Text Available Previous studies on social anxiety have demonstrated negative-expectancy bias in social contexts. In this study, we used a paradigm that employed self-relevant positive or negative social feedback, in order to test whether this negative expectancy manifests in event-related potentials (ERPs during social evaluation among socially anxious individuals. Behavioral data revealed that individuals with social anxiety disorder (SAD showed more negative expectancy of peer acceptance both in the experiment and in daily life than did the healthy control (HC participants. Regarding ERP results, we found a overally larger P2 for positive social feedback and also a group main effect, such that the P2 was smaller in SAD group. SAD participants demonstrated a larger FRN to positive feedback than to negative feedback. In addition, SAD participants showed a more positive △FRN (△FRN = negative - positive. Furthermore, acceptance expectancy in daily life correlated negatively with △FRN amplitude, while the Interaction Anxiousness Scale (IAS score correlated positively with the △FRN amplitude. Finally, the acceptance expectancy in daily life fully mediated the relationship between the IAS and △FRN. These results indicated that both groups could differentiate between positive and negative social feedback in the early stage of social feedback processing (reflected on the P2. However, the SAD group exhibited a larger FRN to positive social feedback than to negative social feedback, demonstrating their dysfunction in the late stage of social feedback processing. In our opinion, such dysfunction is due to their greater negative social feedback expectancy.

Social class, sense of control, and social explanation.

Science.gov (United States)

Kraus, Michael W; Piff, Paul K; Keltner, Dacher

2009-12-01

Lower social class is associated with diminished resources and perceived subordinate rank. On the basis of this analysis, the authors predicted that social class would be closely associated with a reduced sense of personal control and that this association would explain why lower class individuals favor contextual over dispositional explanations of social events. Across 4 studies, lower social class individuals, as measured by subjective socioeconomic status (SES), endorsed contextual explanations of economic trends, broad social outcomes, and emotion. Across studies, the sense of control mediated the relation between subjective SES and contextual explanations, and this association was independent of objective SES, ethnicity, political ideology, and self-serving biases. Finally, experimentally inducing a higher sense of control attenuated the tendency for lower subjective SES individuals to make more contextual explanations (Study 4). Implications for future research on social class as well as theoretical distinctions between objective SES and subjective SES are discussed.

Zhou, Yang; Zhang, Lei; Liu, Xiaoqian; Zhang, Zhen; Bai, Shuotian; Zhu, Tingshao

2017-09-01

Growing interest in social events on social media came along with the rapid development of the Internet. Social events that occur in the "real" world can spread on social media (e.g., Sina Weibo) rapidly, which may trigger severe consequences and thus require the government's timely attention and responses. This article proposes to predict the trends of social events on Sina Weibo, which is currently the most popular social media in China. Based on the theories of social psychology and communication sciences, we extract an unprecedented amount of comprehensive and effective features that relate to the trends of social events on Chinese social media, and we construct the trends of prediction models by using three classical regression algorithms. We found that lasso regression performed better with the precision 0.78 and the recall 0.88. The results of our experiments demonstrated the effectiveness of our proposed approach.

Sustained housing-type social buffering following social housing in male rats.

Kiyokawa, Yasushi; Ishida, Aya; Takeuchi, Yukari; Mori, Yuji

In social animals, recovery from the adverse effects of distressing stimuli is promoted by subsequent cohousing with a conspecific animal(s). This phenomenon has been termed housing-type social buffering. We previously found that social housing induced housing-type social buffering in fear-conditioned male rats. This buffering took the form of attenuated conditioned hyperthermia in response to an auditory conditioned stimulus (CS). Here, we assessed whether this social buffering is sustained even if the subject is housed alone after a period of social housing. When fear-conditioned subjects were housed alone during a 48-h period between conditioning and re-exposure to the auditory CS, they exhibited conditioned hyperthermia in response to the CS. However, conditioned hyperthermia was not observed when the 12-h period of social housing began 24 and 36h after conditioning during the 48-h period. This was not the case when the 12-h period of social housing began 0 and 12h after the conditioning. These results suggest that housing-type social buffering is sustained for 12h after the 12-h period of social housing. We next considered whether increasing the duration of social housing would extend the period of social buffering. We observed social buffering of conditioned hyperthermia 24 and 48, but not 96h after a 24-h period of social housing. These results suggest that social buffering was extended when the duration of social housing was increased. Taken together, our findings indicate that housing-type social buffering is sustained after a period of social housing. Copyright © 2016 Elsevier Inc. All rights reserved.

COPD360social Online Community: A Social Media Review.

Science.gov (United States)

Stellefson, Michael; Paige, Samantha R; Alber, Julia M; Stewart, Margaret

2018-06-01

People living with chronic obstructive pulmonary disease (COPD) commonly report feelings of loneliness and social isolation due to lack of support from family, friends, and health care providers. COPD360social is an interactive and disease-specific online community and social network dedicated to connecting people living with COPD to evidence-based resources. Through free access to collaborative forums, members can explore, engage, and discuss an array of disease-related topics, such as symptom management. This social media review provides an overview of COPD360social, specifically its features that practitioners can leverage to facilitate patient-provider communication, knowledge translation, and community building. The potential of COPD360social for chronic disease self-management is maximized through community recognition programming and interactive friend-finding tools that encourage members to share their own stories through blogs and multimedia (e.g., images, videos). The platform also fosters collaborative knowledge dissemination and helping relationships among patients, family members, friends, and health care providers. Successful implementation of COPD360social has dramatically expanded patient education and self-management support resources for people affected by COPD. Practitioners should refer patients and their families to online social networks such as COPD360social to increase knowledge and awareness of evidence-based chronic disease management practices.

Social Engineering hits Social Commerce

Degenhardt, Werner; Wiele, Johannes

Looking at social commerce, a bunch of bewildering phenomena attracts the attention of social psychologists. The way customers participate today shows attitudes and ethical behavior which cannot be explained from the inherent conditions of Web 2.0 environments alone. Fraud often succeeds, when you do not expect it, and honesty can be found under circumstances that do not support honesty at all. The current situation seems to result from customers assigning experience and ethics from real world business to virtual business environments. But there are indications that this situation may change. Social commerce could suffer as soon as customers would use its inherent weaknesses to their own advantage. The following article outlines first approaches to research into this topic.

Peer perceptions of social skills in socially anxious and nonanxious adolescents.

Miers, Anne C; Blöte, Anke W; Westenberg, P Michiel

2010-01-01

Previous studies using adult observers are inconsistent with regard to social skills deficits in nonclinical socially anxious youth. The present study investigated whether same age peers perceive a lack of social skills in the socially anxious. Twenty high and 20 low socially anxious adolescents (13-17 years old) were recorded giving a 5-min speech. Unfamiliar peer observers (12-17 years old) viewed the speech samples and rated four social skills: speech content, facial expressions, posture and body movement, and way of speaking. Peer observers perceived high socially anxious adolescents as significantly poorer than low socially anxious adolescents on all four social skills. Moreover, for all skills except facial expressions, group differences could not be attributed to adolescents' self-reported level of depression. We suggest that therapists take the perceptions of same age peers into account when assessing the social skills of socially anxious youth.

Junto al concepto de redes sociales aparece también el de capital social; un recurso creado por los propios individuos que representa un poder a la hora de ocupar espacios sociales, acceder a recursos, cubrir necesidades, resolver problemas sociales, etc. La existencia de redes sociales fuertes favorece los vínculos democráticos, el nexo entre los diversos agentes e instituciones del territorio, la coordinación de las acciones colectivas y, consecuentemente, la construcción de capital social.

van der Molen, Melle J W; Harrewijn, Anita; Westenberg, P Michiel

2018-03-07

The current study examined neural and behavioral responses to social-evaluative feedback processing in social anxiety. Twenty-two non-socially and 17 socially anxious females (mean age = 19.57 years) participated in a Social Judgment Paradigm in which they received peer acceptance/rejection feedback that was either congruent or incongruent with their prior predictions. Results indicated that socially anxious participants believed they would receive less social acceptance feedback than non-socially anxious participants. EEG results demonstrated that unexpected social rejection feedback elicited a significant increase in theta (4-8 Hz) power relative to other feedback conditions. This theta response was only observed in non-socially anxious individuals. Together, results corroborate cognitive-behavioral studies demonstrating a negative expectancy bias in socially anxiety with respect to social evaluation. Furthermore, the present findings highlight a functional role for theta oscillatory dynamics in processing cues that convey social-evaluative threat, and this social threat-monitoring mechanism seems less sensitive in socially anxious females.

A Scoping Review of Social Media Use in Social Work Practice.

Science.gov (United States)

Chan, Chitat

2016-01-01

The trend of using social media in social work is increasing, but research which systematically reviews and evaluates their uses in actual practice is limited. This article reviews the social work literature to identify the uses, benefits, and limitations of social media in social work practice, and identifies current gaps in the literature to provide recommendations for future social work research. Articles in 64 social work journals published between 2000 and 2014 were screened and analyzed. The included articles (n = 20) were analyzed with particular reference to their level of evidence and ways of social media use. The methodological quality of the studies in this review was low, and this was consistent with the findings of recent systematic reviews of social media use in medical healthcare. The findings initially suggested that social media can potentially contribute to various social work processes, including: service user engagement, need assessment, intervention, and program evaluation. Limitations include lack of quality control, reliability, confidentiality, and privacy. In social work, the dominant research concern in social media is more about professional ethics than their application in intervention. Implications for research and practice are discussed.

A Challenge to the Social Work Profession? The Rise of Socially Engaged Art and a Call to Radical Social Work.

Science.gov (United States)

2017-10-01

In this era of neoliberalism, social work in the United States is arguably overly professionalized and privatized, and has almost lost its activists roots in working for social justice. Radical social work rooted in macro-level community-based practice has been in crisis over the past three decades. The rise of socially engaged art has become more prominent in the United States even as social work has strayed away from its basic tenets such as community practice, advocacy, and social action. How should the social work profession interpret the rise of socially engaged art-already a trend in the art world-whose modality and purpose resembles radical social work? By comparing and contrasting the similarities and differences between radical social work and socially engaged art, this article examines the possibility of consilience between the two and the implications for the social work profession. © 2017 National Association of Social Workers.

In advancing the positive argument, we link developmental psychology to phenomenological insights by focusing on child-caregiver dynamics around the middle of the second year.

Social proof in social media shopping: An experimental design research

Directory of Open Access Journals (Sweden)

Abdul Talib Yurita Yakimin

2017-01-01

Full Text Available The practices of social proof techniques to attract consumers to shop on social media have proliferated over time and been used extensively. The reviewed literature uncovers that social community recommendation, customers’ ratings and reviews, celebrity’s endorser and numbers of likes, affect consumers’ purchasing decisions. However, the effect of different types of social proof techniques on purchasing intention is unknown. This study empirically compares the effect of number of followers, celebrity endorser and social community recommendation on consumers’ purchasing intention. An experiment has been conducted and the results reveal that the consumers’ purchasing intention differs between groups. Further analysis discovers that the impact on consumers’ purchasing intention is different between high number of followers and low number of followers, and between having social community recommendation and not having social community recommendation. Though, the impact of these two techniques is equal wherein no technique is superior to other. In order to gain purchasing engagement and boost online sales, online businesses on social media are encouraged to use the power of social proof technique, either by increasing the number of followers or providing more social community recommendations.

Social anxiety and social norms in individualistic and collectivistic countries.

Social anxiety is assumed to be related to cultural norms across countries. Heinrichs et al. [2006: Behav Res Ther 44:1187-1197] compared individualistic and collectivistic countries and found higher social anxiety and more positive attitudes toward socially avoidant behaviors in collectivistic rather than in individualistic countries. However, the authors failed to include Latin American countries in the collectivistic group. To provide support for these earlier results within an extended sample of collectivistic countries, 478 undergraduate students from individualistic countries were compared with 388 undergraduate students from collectivistic countries (including East Asian and Latin American) via self-report of social anxiety and social vignettes assessing social norms. As expected, the results of Heinrichs et al. [2006: Behav Res Ther 44:1187-1197] were replicated for the individualistic and Asian countries, but not for Latin American countries. Latin American countries displayed the lowest social anxiety levels, whereas the collectivistic East Asian group displayed the highest. These findings indicate that while culture-mediated social norms affect social anxiety and might help to shed light on the etiology of social anxiety disorder, the dimension of individualism-collectivism may not fully capture the relevant norms. © 2010 Wiley-Liss, Inc.

OXTR polymorphism predicts social relationships through its effects on social temperament.

Science.gov (United States)

Creswell, Kasey G; Wright, Aidan G C; Troxel, Wendy M; Ferrell, Robert E; Flory, Janine D; Manuck, Stephen B

2015-06-01

Humans have a fundamental need for strong interpersonal bonds, yet individuals differ appreciably in their degree of social integration. That these differences are also substantially heritable has spurred interest in biological mechanisms underlying the quality and quantity of individuals' social relationships. We propose that polymorphic variation in the oxytocin receptor gene (OXTR) associates with complex social behaviors and social network composition through intermediate effects on negative affectivity and the psychological processing of socially relevant information. We tested a hypothesized social cascade from the molecular level (OXTR variation) to the social environment, through negative affectivity and inhibited sociality, in a sample of 1295 men and women of European American (N = 1081) and African American (N = 214) ancestry. Compared to European Americans having any T allele of rs1042778, individuals homozygous for the alternate G allele reported significantly lower levels of negative affectivity and inhibited sociality, which in turn predicted significantly higher levels of social support and a larger/more diverse social network. Moreover, the effect of rs1042778 variation on social support was fully accounted for by associated differences in negative affectivity and inhibited sociality. Results replicated in the African American sample. Findings suggest that OXTR variation modulates levels of social support via proximal impacts on individual temperament. © The Author (2014).

Examining differences in social integration, social support, and relationship characteristics in social networks may be critical for understanding the character and costs of the social difficulties experienced of borderline personality disorder (BPD). We conducted an ego-based (self-reported, individual) social network analysis of 142 participants recruited from clinical and community sources. Each participant listed the 30 most significant people (called alters) in their social network, then rated each alter in terms of amount of contact, social support, attachment strength and negative interactions. In addition, measures of social integration were determined using participant's report of the connection between people in their networks. BPD was associated with poorer social support, more frequent negative interactions, and less social integration. Examination of alter-by-BPD interactions indicated that whereas participants with low BPD symptoms had close relationships with people with high centrality within their networks, participants with high BPD symptoms had their closest relationships with people less central to their networks. The results suggest that individuals with BPD are at a social disadvantage: Those with whom they are most closely linked (including romantic partners) are less socially connected (i.e., less central) within their social network.

Full Text Available The aim of this article is to analyze theoretically the need to improve Social Studies Education in Turkey in a pedagogical manner and on the basis of the intended contributions and goals of a New Social Studies Movement to the field.Social Studies Education is an important teaching discipline to equip individuals with the necessary knowledge, skills, values and attitudes to operate efficiently in a knowledge society.The New Social Studies movement of 1960s in the USA contributed to the development of Social Studies Education.This movement tried to establish a constructivist approach. They emphasized on the importance of an inquiry based approach, and rich and real life situation in the classrooms and skills such as critical thinking, reflective thinking, cooperation and collaboration in Social Studies Education. However, the movement diminished in a short while due to the lack of research to support their theoretically sound ideas, appropriate teaching resources for teachers and students and ill-equipped teachers while their ideas were and still are gaining impetus in many countries in the world.Social Studies Education is relatively new in Turkey. Social Studies Education in Turkey has weaknesses in terms of both in theoretically and practically. The quality of teaching resources and materials and teacher qualifications are not up-to-standards to carry out a constructivist Social Studies Education.A new movement has started in Turkey to improve Social Studies Education. This new Social Studies movement aims to do research in the field on the area, print books and teaching resource for both teachers and students, develop policies, hold academic meetings, publish high quality journals for both academics and practitioners, to create opportunities and gateways for networking. This article critically argues the proposed contribution of the new Social Studies movement to the field in Turkey drawing upon the experiences of the movement of 1960s in

Social inheritance can explain the structure of animal social networks

Ilany, Amiyaal; Akçay, Erol

2016-01-01

The social network structure of animal populations has major implications for survival, reproductive success, sexual selection and pathogen transmission of individuals. But as of yet, no general theory of social network structure exists that can explain the diversity of social networks observed in nature, and serve as a null model for detecting species and population-specific factors. Here we propose a simple and generally applicable model of social network structure. We consider the emergence of network structure as a result of social inheritance, in which newborns are likely to bond with maternal contacts, and via forming bonds randomly. We compare model output with data from several species, showing that it can generate networks with properties such as those observed in real social systems. Our model demonstrates that important observed properties of social networks, including heritability of network position or assortative associations, can be understood as consequences of social inheritance.

Social identity framing: Leader communication for social change

Science.gov (United States)

Seyranian, Viviane

Social identity framing (SIF) delineates a process of intergroup communication that leaders may engage in to promote a vision of social change. As a step towards social change, social identity may need to be altered to accommodate a new view of the group, its collective goals, and its place alongside other groups. Thus, social identity content may be deconstructed and reconstructed by the leader en route to change. SIF suggests that this may be achieved through a series of 16 communication tactics, which are largely derived from previous research (Seyranian & Bligh, 2008). This research used an experimental design to test the effectiveness of three SIF communication tactics - inclusion, similarity to followers, and positive social identity - on a number of follower outcomes. Students ( N=246) were randomly assigned to read one of eight possible speeches promoting renewable energy on campus that was ostensibly from a student leader. The speeches were varied to include or exclude the three communication tactics. Following the speech, participants completed a dependent measures questionnaire. Results indicated that similarity to followers and positive social identity did not affect follower outcomes. However, students exposed to inclusion were more likely to indicate that renewable energy was ingroup normative; intend to engage in collective action to bring renewable energy to campus; experience positive emotional reactions towards change; feel more confident about the possibility of change; and to view the leader more positively. The combination of inclusion and positive social identity increased perceptions of charismatic leadership. Perceived leader prototypicality and cognitive elaboration of the leader's message resulted in more favorable attitudes towards renewable energy. Perceived leader prototypicality was also directly related to social identification, environmental values, ingroup injunctive norms, and self-stereotypes. Overall, these results support SIF

Full Text Available Gender socialization is key for understanding how genderrelated attitudes become internalized. This paper sheds lights into the gender socialization process and how it is reflected across the four traditional social institutions of family, church, school and mass-media. It advances the argument that gender stereotypes which continue to be enforced across centuries are power-driven social representations for limiting women’ access rights across all social institutions.

Kim, Yonghwan; Wang, Yuan; Oh, Jeyoung

2016-04-01

Social media and mobile phones have emerged as important platforms for college students' communication activities. This study examined how college students' psychological need to belong is associated with their use of social media and smartphones. In addition, it further investigated the effects of college students' digital media use on their social engagement. Findings revealed that students' need to belong was positively related with their use of social media and smartphones, which could further facilitate their social engagement. Moreover, the relationship between the need to belong and social engagement was mediated by college students' digital media use. This study offers empirical evidence of the positive effects of digital media on social behaviors and contributed to further understanding about the mechanisms by which need to belong leads to social engagement through digital media use.

Impairments in social interaction and communication are critical features of ASD but the underlying processes are poorly understood. An under-explored area is the social motor synchronization that happens when we coordinate our bodies with others. Here, we explored the relationships between dynamical measures of social motor synchronization and assessments of ASD traits. We found (a) spontaneous social motor synchronization was associated with responding to joint attention, cooperation, and theory of mind while intentional social motor synchronization was associated with initiating joint attention and theory of mind; and (b) social motor synchronization was associated with ASD severity but not fully explained by motor problems. Findings suggest that objective measures of social motor synchronization may provide insights into understanding ASD traits.

2013-01-01

The prospects for online social networks as sites of information-gathering and affiliation for persons with AIDS and others concerned about HIV/AIDS not only represent the latest development in a trend toward circumventing traditional media and official information sources, but also may offer hope for a revitalization of HIV/AIDS discourse in the public sphere. This article provides an overview of three decades of information-seeking on the pandemic and its social and personal implications, as well as case studies of three examples of social networking surrounding HIV/AIDS. It finds preliminary evidence of the formation of strong and weak ties as described in Social Network Theory and suggests that the online accumulation of social capital by opinion leaders could facilitate dissemination of messages on HIV/AIDS awareness and testing.

Perceived and actual social discrimination: the case of overweight and social inclusion.

Science.gov (United States)

Hartung, Freda-Marie; Renner, Britta

2013-01-01

The present study examined the correspondence between perceived and actual social discrimination of overweight people. In total, 77 first-year students provided self-ratings about their height, weight, and perceived social inclusion. To capture actual social inclusion, each participant nominated those fellow students (a) she/he likes and dislikes and (b) about whom she/he is likely to hear social news. Students with lower Body Mass Index (BMI) felt socially included, irrespective of their actual social inclusion. In contrast, students with higher BMI felt socially included depending on the degree of their actual social inclusion. Specifically, their felt social inclusion accurately reflected whether they were actually liked/disliked, but only when they were part of social news. When not part of social news, they also showed insensitivity to their actual social inclusion status. Thus, students with a lower BMI tended to be insensitive, while students with a higher BMI showed a differential sensitivity to actual social discrimination.

Social Drinking on Social Media: Content Analysis of the Social Aspects of Alcohol-Related Posts on Facebook and Instagram.

Hendriks, Hanneke; Van den Putte, Bas; Gebhardt, Winifred A; Moreno, Megan A

2018-06-22

Alcohol is often consumed in social contexts. An emerging social context in which alcohol is becoming increasingly apparent is social media. More and more young people display alcohol-related posts on social networking sites such as Facebook and Instagram. Considering the importance of the social aspects of alcohol consumption and social media use, this study investigated the social content of alcohol posts (ie, the evaluative social context and presence of people) and social processes (ie, the posting of and reactions to posts) involved with alcohol posts on social networking sites. Participants (N=192; mean age 20.64, SD 4.68 years, 132 women and 54 men) gave researchers access to their Facebook and/or Instagram profiles, and an extensive content analysis of these profiles was conducted. Coders were trained and then coded all screenshotted timelines in terms of evaluative social context, presence of people, and reactions to post. Alcohol posts of youth frequently depict alcohol in a positive social context (425/438, 97.0%) and display people holding drinks (277/412, 67.2%). In addition, alcohol posts were more often placed on participants' timelines by others (tagging; 238/439, 54.2%) than posted by participants themselves (201/439, 45.8%). Furthermore, it was revealed that such social posts received more likes (mean 35.50, SD 26.39) and comments than nonsocial posts (no people visible; mean 10.34, SD 13.19, P<.001). In terms of content and processes, alcohol posts on social media are social in nature and a part of young people's everyday social lives. Interventions aiming to decrease alcohol posts should therefore focus on the broad social context of individuals in which posting about alcohol takes place. Potential intervention strategies could involve making young people aware that when they post about social gatherings in which alcohol is visible and tag others, it may have unintended negative consequences and should be avoided. ©Hanneke Hendriks, Bas Van den

Surprisingly little is known about how such associations are formed, particularly in the social domain. Here, we aimed at testing whether social and non-social category learning may be dissociated. We presented subjects with a large number of faces that had to be rated according to social or non-social labels, and induced an association between a facial feature (inter-eye distance and the category labels using two different procedures. In a first experiment, we used a feedback procedure to reinforce the association; behavioral measures revealed an association between the physical feature manipulated and abstract non-social categories, while no evidence for an association with social labels could be found. In a second experiment, we used passive exposure to the association between physical features and labels; we obtained behavioral evidence for learning of both social and non-social categories. These results support the view of the specificity of social category learning; they suggest that social categories are best acquired through unsupervised procedures that can be considered as a simplified proxy for group transmission.

This longitudinal, naturalistic study addressed behavioral and social cognitive processes implicated in preschool children's social dominance. In the first objective, we examined the degree to which peer aggression, affiliation, and postaggression reconciliation predicted social dominance across a school year. Consistent with predictions, all three predicted dominance early in the year while only affiliation predicted dominance later in the year, suggesting that aggression, affiliation, and reconciliation were used to establish social dominance where affiliation was used to maintain it. In the second, exploratory, objective we tested the relative importance of social dominance and reconciliation (the Machiavellian and Vygotskian intelligence hypotheses, respectively) in predicting theory of mind/false belief. Results indicated that social dominance accounted for significant variance, beyond that related to reconciliation and affiliation, in predicting theory of mind/false belief status. Results are discussed in terms of specific behavioral and social cognitive processes employed in establishing and maintaining social dominance. © 2011 Wiley-Liss, Inc.

Dilemmas in providing resilience-enhancing social services to long-term social assistance clients. A qualitative study of Swedish social workers

Full Text Available Abstract Background Long-term recipients of social assistance face barriers to social and economic inclusion, and have poorer health and more limited opportunities for improving their health than many other groups in the population. During recent decades there have been changes in Swedish social policy, with cutbacks in public benefits and a re-emphasis on means-tested policies. In this context, it is important to investigate the necessary conditions for social workers to offer social assistance and services, as well as the mediating role of social workers between public policies and their clients. Swedish social services aim to promote social inclusion by strengthening the individual´s own resources. We investigated the issues that arise when providing social services to long-term social assistance clients within the framework of resilience, which focuses on the processes leading to positive functioning in adverse conditions. Methods Interviews were conducted with 23 social workers in Stockholm and analysed by qualitative content analysis. Results The main theme to emerge from the interviews concerned the constraints that the social workers faced in providing social services to social assistance clients. The first subtheme focused on dilemmas in the interaction between social workers and clients resulting from the dual role of exercising authority and supporting and building trust with clients. Working conditions of social workers also played a crucial role. The second subtheme addressed the impact of the societal context, such as labour market opportunities and coordination between authorities. Conclusions Overall, we found that social workers to a great extent tried to find individual solutions to structural problems.

This study examines the relationship between peoples' personality traits and social media uses with data from 20 societies (N = 21,314). A measure of the "Big Five" personality traits is tested on key social media dimensions: frequency of use, social interaction, and news consumption. Across diverse societies, findings suggest that while extraversion, agreeableness, and conscientiousness are all positive predictors of different types of social media use, emotional stability and openness are negatively related to them.

Toward a Psychology of Social Change: A Typology of Social Change

2017-01-01

Millions of people worldwide are affected by dramatic social change (DSC). While sociological theory aims to understand its precipitants, the psychological consequences remain poorly understood. A large-scale literature review pointed to the desperate need for a typology of social change that might guide theory and research toward a better understanding of the psychology of social change. Over 5,000 abstracts from peer-reviewed articles were assessed from sociological and psychological publications. Based on stringent inclusion criteria, a final 325 articles were used to construct a novel, multi-level typology designed to conceptualize and categorize social change in terms of its psychological threat to psychological well-being. The typology of social change includes four social contexts: Stability, Inertia, Incremental Social Change and, finally, DSC. Four characteristics of DSC were further identified: the pace of social change, rupture to the social structure, rupture to the normative structure, and the level of threat to one's cultural identity. A theoretical model that links the characteristics of social change together and with the social contexts is also suggested. The typology of social change as well as our theoretical proposition may serve as a foundation for future investigations and increase our understanding of the psychologically adaptive mechanisms used in the wake of DSC.

Corporate Social Responsibility Initiatives Addressing Social Exclusion in Bangladesh

Science.gov (United States)

2009-01-01

The private sector is often seen as a driver of exclusionary processes rather than a partner in improving the health and welfare of socially-excluded populations. However, private-sector initiatives and partnerships—collectively labelled corporate social responsibility (CSR) initiatives—may be able to positively impact social status, earning potential, and access to services and resources for socially-excluded populations. This paper presents case studies of CSR projects in Bangladesh that are designed to reduce social exclusion among marginalized populations and explores whether CSR initiatives can increase economic and social capabilities to reduce exclusion. The examples provide snapshots of projects that (a) increase job-skills and employment opportunities for women, disabled women, and rehabilitated drug-users and (b) provide healthcare services to female workers and their communities. The CSR case studies cover a limited number of people but characteristics and practices replicable and scaleable across different industries, countries, and populations are identified. Common success factors from the case studies form the basis for recommendations to design and implement more CSR initiatives targeting socially-excluded groups. The analysis found that CSR has potential for positive and lasting impact on developing countries, especifically on socially-excluded populations. However, there is a need for additional monitoring and critical evaluation. PMID:19761088

Analysing Discourse. An Approach From the Sociology of Knowledge

Reiner Keller

2005-09-01

Full Text Available The contribution outlines a research pro­gramme which I have coined the "sociology of knowledge approach to discourse" (Wissens­sozio­logische Diskursanalyse. This approach to dis­course integrates important insights of FOU­CAULT's theory of discourse into the interpretative paradigm in the social sciences, especially the "German" approach of hermeneutic sociology of knowledge (Hermeneutische Wissenssoziologie. Accordingly, in this approach discourses are con­sidered as "structured and structuring structures" which shape social practices of enunciation. Un­like some Foucauldian approaches, this form of discourse analysis recognises the importance of socially constituted actors in the social production and circulation of knowledge. Furthermore, it com­bines research questions related to the concept of "discourse" with the methodical toolbox of qual­itative social research. Going beyond ques­tions of language in use, "the sociology of knowl­edge ap­proach to discourse" (Wissenssozio­logi­sche Dis­kurs­analyse addresses sociological inter­ests, the analyses of social relations and politics of knowl­edge as well as the discursive construction of re­al­ity as an empirical ("material" process. For empiri­cal research on discourse the approach proposes the use of analytical concepts from the sociology of knowledge tradition, such as inter­pretative schemes or frames (Deutungsmuster, "clas­sifi­ca­tions", "phenomenal structure" (Phäno­men­struktur, "narrative structure", "dispositif" etc., and the use of the methodological strategies of "grounded theory".

Social carry-over effects on non-social behavioral variation: mechanisms and consequences

Directory of Open Access Journals (Sweden)

Petri Toivo Niemelä

2015-05-01

Full Text Available The field of animal personality is interested in decomposing behaviors into different levels of variation, with its present focus on the ecological and evolutionary causes and consequences of expressed variation. Recently the role of the social environment, i.e. social partners, has been suggested to affect behavioral variation and induce selection on animal personality. Social partner effects exist because characters of social partners (e.g. size, behavior, affect the behavioral expression of a focal individual. Here, we 1 first review the proximate mechanisms underlying the social partner effects on behavioral expression and the timescales at which such effects might take place. We then 2 discuss how within- and among-individual variation in single behaviors and covariation between multiple behaviors, caused by social partners, can carry-over to non-social behaviors expressed outside the social context. Finally, we 3 highlight evolutionary consequences of social carry-over effects to non-social behaviors and 4 suggest study designs and statistical approaches which can be applied to study the nature and evolutionary consequences of social carry-over effects on non-social behaviors. Understanding the proximate mechanisms underpinning the social partner effects is important since it opens a door for deeper understanding of how social environments can affect behavioral variation and covariation at multiple levels, and the evolution of non-social behaviors (i.e. exploration, activity, boldness that are affected by social interactions.

Finite-element simulations of the influence of pore wall adsorption on cyclic voltammetry of ion transfer across a liquid-liquid interface formed at a micropore.

Ellis, Jonathan S; Strutwolf, Jörg; Arrigan, Damien W M

2012-02-21

Adsorption onto the walls of micropores was explored by computational simulations involving cyclic voltammetry of ion transfer across an interface between aqueous and organic phases located at the micropore. Micro-interfaces between two immiscible electrolyte solutions (micro-ITIES) have been of particular research interest in recent years and show promise for biosensor and biomedical applications. The simulation model combines diffusion to and within the micropore, Butler-Volmer kinetics for ion transfer at the liquid-liquid interface, and Langmuir-style adsorption on the pore wall. Effects due to pore radius, adsorption and desorption rates, surface adsorption site density, and scan rates were examined. It was found that the magnitude of the reverse peak current decreased due to adsorption of the transferring ion on the pore wall; this decrease was more marked as the scan rate was increased. There was also a shift in the half-wave potential to lower values following adsorption, consistent with a wall adsorption process which provides a further driving force to transfer ions across the ITIES. Of particular interest was the disappearance of the reverse peak from the cyclic voltammogram at higher scan rates, compared to the increase in the reverse peak size in the absence of wall adsorption. This occurred for scan rates of 50 mV s(-1) and above and may be useful in biosensor applications using micropore-based ITIES.

Optimisation of the conditions for stripping voltammetric analysis at liquid-liquid interfaces supported at micropore arrays: a computational simulation.

Strutwolf, Jörg; Arrigan, Damien W M

2010-10-01

Micropore membranes have been used to form arrays of microinterfaces between immiscible electrolyte solutions (µITIES) as a basis for the sensing of non-redox-active ions. Implementation of stripping voltammetry as a sensing method at these arrays of µITIES was applied recently to detect drugs and biomolecules at low concentrations. The present study uses computational simulation to investigate the optimum conditions for stripping voltammetric sensing at the µITIES array. In this scenario, the diffusion of ions in both the aqueous and the organic phases contributes to the sensing response. The influence of the preconcentration time, the micropore aspect ratio, the location of the microinterface within the pore, the ratio of the diffusion coefficients of the analyte ion in the organic and aqueous phases, and the pore wall angle were investigated. The simulations reveal that the accessibility of the microinterfaces during the preconcentration period should not be hampered by a recessed interface and that diffusional transport in the phase where the analyte ions are preconcentrated should be minimized. This will ensure that the ions are accumulated within the micropores close to the interface and thus be readily available for back transfer during the stripping process. On the basis of the results, an optimal combination of the examined parameters is proposed, which together improve the stripping voltammetric signal and provide an improvement in the detection limit.

Bumblebees exhibit the memory spacing effect

Associative learning is key to how bees recognize and return to rewarding floral resources. It thus plays a major role in pollinator floral constancy and plant gene flow. Honeybees are the primary model for pollinator associative learning, but bumblebees play an important ecological role in a wider range of habitats, and their associative learning abilities are less well understood. We assayed learning with the proboscis extension reflex (PER), using a novel method for restraining bees (capsules) designed to improve bumblebee learning. We present the first results demonstrating that bumblebees exhibit the memory spacing effect. They improve their associative learning of odor and nectar reward by exhibiting increased memory acquisition, a component of long-term memory formation, when the time interval between rewarding trials is increased. Bombus impatiens forager memory acquisition (average discrimination index values) improved by 129% and 65% at inter-trial intervals (ITI) of 5 and 3 min, respectively, as compared to an ITI of 1 min. Memory acquisition rate also increased with increasing ITI. Encapsulation significantly increases olfactory memory acquisition. Ten times more foragers exhibited at least one PER response during training in capsules as compared to traditional PER harnesses. Thus, a novel conditioning assay, encapsulation, enabled us to improve bumblebee-learning acquisition and demonstrate that spaced learning results in better memory consolidation. Such spaced learning likely plays a role in forming long-term memories of rewarding floral resources.

Information Systems’ Portfolio: Contributions of Enterprise and Process Architecture

Silvia Fernandes

2017-09-01

Full Text Available We are witnessing a need for a quick and intelligent reaction from organizations to the level and speed of change in business processes.New information technologies and systems (IT/IS are challenging business models and products. One of the great shakes comes from the online and/or mobile apps and platforms.These are having a tremendous impact in launching innovative and competitive services through the combination of digital and physical features. This leads to actively rethink enterprise information systems’ portfolio, its management and suitability. One relevant way for enterprises to manage their IT/IS in order to cope with those challenges is enterprise and process architecture. A decision-making culture based on processes helps to understand and define the different elements that shape an organization and how those elements inter-relate inside and outside it. IT/IS portfolio management requires an increasing need of modeling data and process flows for better discerning and acting at its selection and alignment with business goals. The new generation of enterprise architecture (NGEA helps to design intelligent processes that answer quickly and creatively to new and challenging trends. This has to be open, agile and context-aware to allow well-designed services that match users’ expectations. This study includes two real cases/problems to solve quickly in companies and solutions are presented in line with this architectural approach.

Polymedia and Ethnography: Understanding the Social in Social Media

2015-04-01

Full Text Available In this essay I argue that social media need to be understood as part of complex environments of communicative opportunities which I conceptualize as polymedia. This approach shifts our attention from social media as discrete platforms to the ways users navigate environments of affordances in order to manage their social relationships. Ethnography emerges as the most appropriate method to capture the relational dynamics that underpin social media practices within polymedia.

Social network sites: Indispensable or optional social tools?

Much research has enumerated potential benefits of online social network sites. Given the pervasiveness of these sites and the numbers of people that use them daily, both re-search and media tend to make the assumption that social network sites have become indispensible to their users. Based...... on the analysis of qualitative data from users of social network sites in Russia and Kazakhstan, this paper consid-ers under what conditions social network sites can become indispensable to their users and when these technologies remain on the periphery of life despite fulfilling useful func-tions. For some...... respondents, these sites had become indis-pensable tools as they were integrated into everyday rou-tines of communicating with emotionally important and proximal contacts and were often used for coordination of offline activities.

Social thermoregulation as a potential mechanism linking sociality and fitness: Barbary macaques with more social partners form larger huddles.

Individuals with more or stronger social bonds experience enhanced survival and reproduction in various species, though the mechanisms mediating these effects are unclear. Social thermoregulation is a common behaviour across many species which reduces cold stress exposure, body heat loss, and homeostatic energy costs, allowing greater energetic investment in growth, reproduction, and survival, with larger aggregations providing greater benefits. If more social individuals form larger thermoregulation aggregations due to having more potential partners, this would provide a direct link between sociality and fitness. We conducted the first test of this hypothesis by studying social relationships and winter sleeping huddles in wild Barbary macaques (Macaca sylvanus), wherein individuals with more social partners experience greater probability of winter survival. Precipitation and low temperature increased huddle sizes, supporting previous research that huddle size influences thermoregulation and energetics. Huddling relationships were predicted by social (grooming) relationships. Individuals with more social partners therefore formed larger huddles, suggesting reduced energy expenditure and exposure to environmental stressors than less social individuals, potentially explaining how sociality affects survival in this population. This is the first evidence that social thermoregulation may be a direct proximate mechanism by which increased sociality enhances fitness, which may be widely applicable across taxa.

Human social genomics.

Directory of Open Access Journals (Sweden)

Steven W Cole

2014-08-01

Full Text Available A growing literature in human social genomics has begun to analyze how everyday life circumstances influence human gene expression. Social-environmental conditions such as urbanity, low socioeconomic status, social isolation, social threat, and low or unstable social status have been found to associate with differential expression of hundreds of gene transcripts in leukocytes and diseased tissues such as metastatic cancers. In leukocytes, diverse types of social adversity evoke a common conserved transcriptional response to adversity (CTRA characterized by increased expression of proinflammatory genes and decreased expression of genes involved in innate antiviral responses and antibody synthesis. Mechanistic analyses have mapped the neural "social signal transduction" pathways that stimulate CTRA gene expression in response to social threat and may contribute to social gradients in health. Research has also begun to analyze the functional genomics of optimal health and thriving. Two emerging opportunities now stand to revolutionize our understanding of the everyday life of the human genome: network genomics analyses examining how systems-level capabilities emerge from groups of individual socially sensitive genomes and near-real-time transcriptional biofeedback to empirically optimize individual well-being in the context of the unique genetic, geographic, historical, developmental, and social contexts that jointly shape the transcriptional realization of our innate human genomic potential for thriving.

The Social Industry

Directory of Open Access Journals (Sweden)

Christian Sandvig

2015-04-01

Full Text Available Historical mass media and contemporary social media are typically seen as opposites. “The culture industry” was the term used by the Frankfurt School in the 1940s to explain the emerging commercial mass media. The culture industry was portrayed as a semi-fascist apparatus of indoctrination. It selected cultural products and made them popular based on obscure determinations of economic value. In contrast, the common view of contemporary social media is that it is more democratic. Using voting algorithms and human voting, social media can finally realize widespread participation that was denied to the passive audiences of the mass media system. Social media appear to remove the bottleneck of the mass media system, allowing everyone to aspire to celebrity, or at least popularity. However, despite these appearances, social media have also now evolved into an elaborate system that selects social products and makes them popular based on obscure determinations of economic value. Social media platforms filter, censor, control, and train—and they may do so without the user’s awareness. Advances in computation now make a social media industry possible that is based on individual difference and action rather than sameness and passivity. But in other respects, the social industry resembles the culture industry: the co-option of culture has been superseded by the co-option of sociality. The word “social” may then be the biggest challenge facing those who study social media. Our task is to rescue genuine sociality from the emerging social industry.

Pro-social 50-kHz ultrasonic communication in rats: post-weaning but not post-adolescent social isolation leads to social impairments—phenotypic rescue by re-socialization

Seffer, Dominik; Rippberger, Henrike; Schwarting, Rainer K. W.; Wöhr, Markus

2015-01-01

Rats are highly social animals and social play during adolescence has an important role for social development, hence post-weaning social isolation is widely used to study the adverse effects of juvenile social deprivation and to induce behavioral phenotypes relevant to neuropsychiatric disorders, like schizophrenia. Communication is an important component of the rat's social behavior repertoire, with ultrasonic vocalizations (USV) serving as situation-dependent affective signals. High-frequency 50-kHz USV occur in appetitive situations and induce approach behavior, supporting the notion that they serve as social contact calls; however, post-weaning isolation effects on the behavioral changes displayed by the receiver in response to USV have yet to be studied. We therefore investigated the impact of post-weaning isolation on socio-affective information processing as assessed by means of our established 50-kHz USV radial maze playback paradigm. We showed that post-weaning social isolation specifically affected the behavioral response to playback of pro-social 50-kHz but not alarm 22-kHz USV. While group-housed rats showed the expected preference, i.e., approach, toward 50-kHz USV, the response was even stronger in short-term isolated rats (i.e., 1 day), possibly due to a higher level of social motivation. In contrast, no approach was observed in long-term isolated rats (i.e., 4 weeks). Importantly, deficits in approach were reversed by peer-mediated re-socialization and could not be observed after post-adolescent social isolation, indicating a critical period for social development during adolescence. Together, these results highlight the importance of social experience for affiliative behavior, suggesting a critical involvement of play behavior on socio-affective information processing in rats.

Westdahl, Claire; Milan, Stephanie; Magriples, Urania; Kershaw, Trace S.; Rising, Sharon Schindler; Ickovics, Jeannette R.

2008-01-01

OBJECTIVE To estimate how social support and social conflict relate to prenatal depressive symptoms and to generate a brief clinical tool to identify women at increased psychosocial risk. METHODS This is a prospective study following 1,047 pregnant women receiving care at two university-affiliated clinics from early pregnancy through 1 year postpartum. Structured interviews were conducted in the second trimester of pregnancy. Hierarchical and logistic regressions were used to examine potential direct and interactive effects of social support and conflict on prenatal depressive symptoms measured by the Center for Epidemiologic Studies-Depression Scale. RESULTS Thirty-three percent of the sample reported elevated levels of depressive symptoms predicted from sociodemographic factors, social support, and social conflict. Social support and conflict had independent effects on depressive symptoms although social conflict was a stronger predictor. There was a “dose–response,” with each increase in interpersonal risk factor resulting in consequent risk for probable depression based on symptom reports (Center for Epidemiologic Studies-Scale greater than or equal to 16). A composite of one social support and three conflict items were identified to be used by clinicians to identify interpersonal risk factors for depression in pregnancy. Seventy-six percent of women with a composite score of three or more high-risk responses reported depressive symptoms. CONCLUSION Increased assessment of social support and social conflict by clinicians during pregnancy can identify women who could benefit from group or individual interventions to enhance supportive and reduce negative social interactions.

Social stratification has important implications for health and well-being, with individuals lower in standing in a hierarchy experiencing worse outcomes than those higher up the social ladder. Separate lines of past research suggest that alterations in inflammatory processes and neural responses to threat may link lower social status with poorer outcomes. This study was designed to bridge these literatures to investigate the neurocognitive mechanisms linking subjective social status and inflammation. Thirty-one participants reported their subjective social status, and underwent a functional magnetic resonance imaging scan while they were socially evaluated. Participants also provided blood samples before and after the stressor, which were analysed for changes in inflammation. Results showed that lower subjective social status was associated with greater increases in inflammation. Neuroimaging data revealed lower subjective social status was associated with greater neural activity in the dorsomedial prefrontal cortex (DMPFC) in response to negative feedback. Finally, results indicated that activation in the DMPFC in response to negative feedback mediated the relation between social status and increases in inflammatory activity. This study provides the first evidence of a neurocognitive pathway linking subjective social status and inflammation, thus furthering our understanding of how social hierarchies shape neural and physiological responses to social interactions. © The Author (2016).

2012-01-01

Full Text Available Through analysis of the nature and character of media practice, the paper shows that the media are basic political instrument of manipulative social control of the democratic order. Control of social reality as a fundamental social role of the media stems from the manipulative power of the media that is based in the strategies of production and control of the symbolic potential of the society. Through the production and control of the symbolic potential of the society, the media transform symbolic power in social action or absence of social action through homogenization and activate individuals and social groups in public opinion or their dispersion and breaking off in the public. Development of manipulation, control, oppression, domination and hegemony, the media becomes a product of instrumentalist mind which contributing 'colonization of the lifeworld' and the development of modern society which on a rational way becoming totalitarian.

We review the current state of social communication between healthcare professionals, the role of consumer social networking, and some emerging technologies to address the gaps. In particular, the review covers (1) the current state of loose social networking for continuing medical education (CME) and other broadcast information dissemination; (2) social networking for business promotion; (3) social networking for peer collaboration, including simple communication as well as more robust data-centered collaboration around patient care; and (4) engaging patients on social platforms, including integrating consumer-originated data into the mix of healthcare data. We will see how, as the nature of healthcare delivery moves from the institution-centric way of tradition to a more social and networked ambulatory pattern that we see emerging today, the nature of health IT has also moved from enterprise-centric systems to more socially networked, cloud-based options.

Social structure and indirect genetic effects: genetics of social behaviour.

Schneider, Jonathan; Atallah, Jade; Levine, Joel D

2017-05-01

The social environment modulates gene expression, physiology, behaviour and patterns of inheritance. For more than 50 years, this concept has been investigated using approaches that include partitioning the social component out of behavioural heritability estimates, studying maternal effects on offspring, and analysing dominance hierarchies. Recent advances have formalized this 'social environment effect' by providing a more nuanced approach to the study of social influences on behaviour while recognizing evolutionary implications. Yet, in most of these formulations, the dynamics of social interactions are not accounted for. Also, the reciprocity between individual behaviour and group-level interactions has been largely ignored. Consistent with evolutionary theory, the principles of social interaction are conserved across a broad range of taxa. While noting parallels in diverse organisms, this review uses Drosophila melanogaster as a case study to revisit what is known about social interaction paradigms. We highlight the benefits of integrating the history and pattern of interactions among individuals for dissecting molecular mechanisms that underlie social modulation of behaviour. © 2016 The Authors.

Social economy development is a process underway, innovative in terms of relating the individual to the production processes, the concept of citizenship, production areas and modalities. The concern for sustainable development, analysis of economic and financial crisis, the issue of the relationship between the individual and the production process open up many opportunities for development that can influence public policies on employment and social cohesion.
