Time for action: key considerations for implementing social accountability in the education of health professionals.

PubMed

Ventres, William; Boelen, Charles; Haq, Cynthia

2017-09-12

Within health professional education around the world, there exists a growing awareness of the professional duty to be socially responsible, being attentive to the needs of all members of communities, regions, and nations, especially those who disproportionately suffer from the adverse influence of social determinants. However, much work still remains to progress beyond such good intentions. Moving from contemplation to action means embracing social accountability as a key guiding principle for change. Social accountability means that health institutions attend to improving the performance of individual practitioners and health systems by directing educational and practice interventions to promote the health of all the public and assessing the systemic effects of these interventions. In this Reflection, the authors (1) review the reasons why health professional schools and their governing bodies should codify, in both curricular and accreditation standards, norms of excellence in social accountability, (2) present four considerations crucial to successfully implementing this codification, and (3) discuss the challenges such changes might entail. The authors conclude by noting that in adopting socially accountable criteria, schools will need to expand their philosophical scope to recognize social accountability as a vitally important part of their institutional professional identity.

A topological system for delineation and codification of the Earth's river basins

USGS Publications Warehouse

Verdin, K.L.; Verdin, J.P.

1999-01-01

A comprehensive reference system for the Earth's river basins is proposed as a support to fiver basin management, global change research, and the pursuit of sustainable development. A natural system for delineation and codification of basins is presented which is based upon topographic control and the topology of the fiver network. These characteristics make the system well suited for implementation and use with digital elevation models (DEMs) and geographic information systems. A demonstration of these traits is made with the 30-arcsecond GTOPO30 DEM for North America. The system has additional appeal owing to its economy of digits and the topological information that they carry. This is illustrated through presentation of comparisons with USGS hydrologic unit codes and demonstration of the use of code numbers to reveal dependence or independence of water use activities within a basin.

The purpose of this paper is to describe the design of customer knowledge management system to support customer relationship management activities for an aglaonema nursery in South Tangerang, Indonesia. System. The steps were knowledge identification (knowledge about customer, knowledge from customer, knowledge for customer), knowledge capture, codification, analysis of system requirement and create use case and activity diagram. The result showed that some key knowledge were about supporting customer in plant care (know how) and types of aglaonema including with the prices (know what). That knowledge for customer then codified and shared in knowledge portal website integrated with social media. Knowledge about customer were about customers and their behaviour in purchasing aglaonema. Knowledge from customer were about feedback, favorite and customer experience. Codified knowledge were placed and shared using content management system based on wordpress.

From individual coping strategies to illness codification: the reflection of gender in social science research on multiple chemical sensitivities (MCS).

PubMed

Nadeau, Geneviève; Lippel, Katherine

2014-09-10

Emerging fields such as environmental health have been challenged, in recent years, to answer the growing methodological calls for a finer integration of sex and gender in health-related research and policy-making. Through a descriptive examination of 25 peer-reviewed social science papers published between 1996 and 2011, we explore, by examining methodological designs and theoretical standpoints, how the social sciences have integrated gender sensitivity in empirical work on Multiple Chemical Sensitivities (MCS). MCS is a "diagnosis" associated with sensitivities to chronic and low-dose chemical exposures, which remains contested in both the medical and institutional arenas, and is reported to disproportionately affect women. We highlighted important differences between papers that did integrate a gender lens and those that did not. These included characteristics of the authorship, purposes, theoretical frameworks and methodological designs of the studies. Reviewed papers that integrated gender tended to focus on the gender roles and identity of women suffering from MCS, emphasizing personal strategies of adaptation. More generally, terminological confusions in the use of sex and gender language and concepts, such as a conflation of women and gender, were observed. Although some men were included in most of the study samples reviewed, specific data relating to men was undereported in results and only one paper discussed issues specifically experienced by men suffering from MCS. Papers that overlooked gender dimensions generally addressed more systemic social issues such as the dynamics of expertise and the medical codification of MCS, from more consistently outlined theoretical frameworks. Results highlight the place for a critical, systematic and reflexive problematization of gender and for the development of methodological and theoretical tools on how to integrate gender in research designs when looking at both micro and macro social dimensions of environmental health conditions. This paper contributes to a discussion on the methodological and policy implications of taking sex and gender into account appropriately in order to contribute to better equity in health, especially where the critical social contexts of definition and medico-legal recognition play a major role such as in the case of MCS.

Associations between task, training and social environmental factors and error types involved in rail incidents and accidents.

PubMed

Read, Gemma J M; Lenné, Michael G; Moss, Simon A

2012-09-01

Rail accidents can be understood in terms of the systemic and individual contributions to their causation. The current study was undertaken to determine whether errors and violations are more often associated with different local and organisational factors that contribute to rail accidents. The Contributing Factors Framework (CFF), a tool developed for the collection and codification of data regarding rail accidents and incidents, was applied to a sample of investigation reports. In addition, a more detailed categorisation of errors was undertaken. Ninety-six investigation reports into Australian accidents and incidents occurring between 1999 and 2008 were analysed. Each report was coded independently by two experienced coders. Task demand factors were significantly more often associated with skill-based errors, knowledge and training deficiencies significantly associated with mistakes, and violations significantly linked to social environmental factors.

Clean Energy in City Codes: A Baseline Analysis of Municipal Codification across the United States

DOE Office of Scientific and Technical Information (OSTI.GOV)

Cook, Jeffrey J.; Aznar, Alexandra; Dane, Alexander

Municipal governments in the United States are well positioned to influence clean energy (energy efficiency and alternative energy) and transportation technology and strategy implementation within their jurisdictions through planning, programs, and codification. Municipal governments are leveraging planning processes and programs to shape their energy futures. There is limited understanding in the literature related to codification, the primary way that municipal governments enact enforceable policies. The authors fill the gap in the literature by documenting the status of municipal codification of clean energy and transportation across the United States. More directly, we leverage online databases of municipal codes to develop nationalmore » and state-specific representative samples of municipal governments by population size. Our analysis finds that municipal governments with the authority to set residential building energy codes within their jurisdictions frequently do so. In some cases, communities set codes higher than their respective state governments. Examination of codes across the nation indicates that municipal governments are employing their code as a policy mechanism to address clean energy and transportation.« less

Australian tort law reform: statutory principles of causation and the common law.

PubMed

Mendelson, Danuta

2004-05-01

By mid-2004, Parliaments in each Australian jurisdiction will either complete or will be in the process of partial codification of the law of torts. The reforms, including those to the law of negligence, are extensive. This article focuses on codification of the law of causation as an element of the cause of action in negligence. It examines the background to "tort reform", as the process has been labelled, and discusses the common law paradigm of negligence and various approaches to causation. It then analyses and compares the causation provisions in each jurisdiction.

Why am I not disabled? Making state subjects, making statistics in post--Mao China.

PubMed

Kohrman, Matthew

2003-03-01

In this article I examine how and why disability was defined and statistically quantified by China's party-state in the late 1980s. I describe the unfolding of a particular epidemiological undertaking--China's 1987 National Sample Survey of Disabled Persons--as well as the ways the survey was an extension of what Ian Hacking has called modernity's "avalanche of numbers." I argue that, to a large degree, what fueled and shaped the 1987 survey's codification and quantification of disability was how Chinese officials were incited to shape their own identities as they negotiated an array of social, political, and ethical forces, which were at once national and transnational in orientation.

Comparison of four DNA extraction methods for the detection of Mycobacterium leprae from Ziehl-Neelsen-stained microscopic slides.

2015-12-01

The diagnosis of leprosy has been a challenge due to the low sensibility of the conventional methods and the impossibility of culturing the causative organism. In this study, four methods for Mycobacterium leprae nucleic-acid extraction from Ziehl-Neelsen-stained slides (ZNS slides) were compared: Phenol/chloroform, Chelex 100 resin, and two commercial kits (Wizard Genomic DNA Purification Kit and QIAamp DNA Mini Kit). DNA was extracted from four groups of slides: a high-codification-slide group (bacteriological index [BI]⩾4), a low-codification-slide group (BI=1), a negative-slide group (BI=0), and a negative-control-slide group (BI=0). Quality DNA was evidenced by the amplification of specific repetitive element present in M. leprae genomic DNA (RLEP) using a nested polymerase chain reaction. This is the first report comparing four different extraction methods for obtaining M. leprae DNA from ZNS slides in Cuban patients, and applied in molecular diagnosis. Good-quality DNA and positive amplification were detected in the high-codification-slide group with the four methods, while from the low-codification-slide group only the QIAGEN and phenol-chloroform methods obtained amplification of M. leprae. In the negative-slide group, only the QIAGEN method was able to obtain DNA with sufficient quality for positive amplification of the RLEP region. No amplification was observed in the negative-control-slide group by any method. Patients with ZNS negative slides can still transmit the infection, and molecular methods can help identify and treat them, interrupting the chain of transmission and preventing the onset of disabilities. The ZNS slides can be sent easily to reference laboratories for later molecular analysis that can be useful not only to improve the diagnosis, but also for the application of other molecular techniques.

On knowledge transfer management as a learning process for ad hoc teams

NASA Astrophysics Data System (ADS)

Iliescu, D.

2017-08-01

Knowledge management represents an emerging domain becoming more and more important. Concepts like knowledge codification and personalisation, knowledge life-cycle, social and technological dimensions, knowledge transfer and learning management are integral parts. Focus goes here in the process of knowledge transfer for the case of ad hoc teams. The social dimension of knowledge transfer plays an important role. No single individual actors involved in the process, but a collective one, representing the organisation. It is critically important for knowledge to be managed from the life-cycle point of view. A complex communication network needs to be in place to supports the process of knowledge transfer. Two particular concepts, the bridge tie and transactive memory, would eventually enhance the communication. The paper focuses on an informational communication platform supporting the collaborative work on knowledge transfer. The platform facilitates the creation of a topic language to be used in knowledge modelling, storage and reuse, by the ad hoc teams.

The Informational Patterns of Laughter

NASA Astrophysics Data System (ADS)

Bea, José A.; Marijuán, Pedro C.

2003-06-01

Laughter is one of the most characteristic -and enigmatic- communicational traits of human individuals. Its analysis has to take into account a variety of emotional, social, cognitive, and communicational factors densely interconnected. In this article we study laughter just as an auditive signal (as a 'neutral' information carrier), and we compare its structure with the regular traits of linguistic signals. In the experimental records of human laughter that we have performed, the most noticeable trait is the disorder content of frequencies. In comparison with the sonograms of vowels, the information content of which appears as a characteristic, regular function of the first vibration modes of the dynamic system formed, for each vowel, by the vocal cords and the accompanying resonance of the vocalization apparatus, the sonograms of laughter are highly irregular. In the episodes of laughter, a highly random content in frequencies appears, reason why it cannot be considered as a genuine codification of patterned information like in linguistic signals. In order to numerically gauge the disorder content of laughter frequencies, we have performed several "entropy" measures of the spectra -trying to unambiguously identify spontaneous laughter from "faked", articulated laughter. Interestingly, Shannon's entropy (the most natural candidate) performs rather poorly.

The law of doctoring: a study of the codification of medical professionalism.

PubMed

Fichter, Andrew

2009-01-01

This essay argues that the concept of professionalism as it appears in health law is undergoing transformation as the applicable common law doctrines are increasingly being superseded by statutes and regulations. The doctor-patient relationship is being subjected to new rules of conduct intended to affirm the rights not only of patients but also of society at large. The bilateral relationship between doctor and patient has in many respects been transformed into a triadic one in which the concerns of public, as consumer and payor, are increasingly taken into account. In many respects this change has been necessary and inevitable as medicine has become a more commercial enterprise; but the change has also put traditional notions of professionalism at risk. Where professionalism is adversely affected by the process of its codification, it is incumbent upon law and policy makers to be aware of the fact. To this end, this essay first undertakes to define medical professionalism as a legal construct, and then formulates an analytic method with which to determine when professionalism is implicated and whether it is adequately accommodated by the law. The definition of professionalism the author advances is informed by concepts established in the literature of sociology, which identifies four core attributes-functional specificity, trust, disinterestedness and self-regulation. Each of these attributes is examined in turn with reference to case law selected to identify the value in question and to illustrate the nature of the change resulting from its codification.

The evolution of behavior guidance: a history of professional, practice, corporate and societal influences.

PubMed

Strange, David M

2014-01-01

Behavior guidance in pediatric dentistry is a composite of influences including expert opinion, historical precedent, scientific studies, and social factors including the law and the media. The early icons of pediatric dentistry injected their personal views on child management, and those often reflected the child-rearing norms of the times. The business of pediatric dentistry with its efficiency and quality orientations also shaped approaches to behavior management. Scientific studies contributed minimally. A major influence on behavior guidelines in recent years has been external scrutiny of techniques prompted by media and other exposure of both private practice and corporate management of children. Changing parenting and reaction of society to authority have also had significant impact on behavior. This paper describes in more detail the evolution of behavior guidance and the subsequent codification of practices into professionally derived guidelines.

Demonstration that DRM is a component of inefficiency and hiring a specialist physician for its detection and treatment is cost-effective. Comparison between nutritional diagnosis and procedures detected and encoded at discharge using McNemar test. Recoding of 162 discharge reports including nutritional diagnoses and procedures. Determine changes on Case-Mix Index (IC), cost of procedure and cost procedure/DRG index. Comparison using T-student paired test. Only 10 of 162 diagnoses of malnutrition were coded in delivery statements (p < 0.001). After right codification, IC increased in 103,3 DRG points (p < 0.001). Consequently, procedure cost/DRG index was reduced in 978.81 € (p < 0.001). DRM is underdiagnosed in our hospital. DRM and nutritional procedures detection by a doctor specialist in clinical nutrition led to a reduction in cost procedure/DRG index of 16.8% of officially established by the Health System. Loss of 16.8% of health expenses, estimated in 424.785,15 € was described. Proper codification would have justified 343.291,2 € reimbursement just for nutritional diagnoses and processes. Both expenses were lost due to system's inefficiency. Those amounts are much higher than cost associated of hiring a specialist in clinical nutrition.

[Patient information in urology: current legal situation with particular emphasis on the codification of the contract governing medical treatment in the German Civil Code (BGB)].

PubMed

Fischer, C; Petersilie, F

2014-12-01

The extent and specification of patient information have so far been defined by case law. Henceforth, the rules of patient information are included in a new type of contract, a contract governing medical treatment (Behandlungsvertrag), codified in §§630a-630e of the German Civil Code (BGB). The main conclusions of the case law are now governed by law; however, some new requirements, such as the obligation to inform patients about treatment errors or the stipulation to deliver copies of undersigned documents have been added. This article gives an overview of the codification of patient information, explains how to inform patients, particularly in urology and illustrates where it is still likely that law courts will be concerned with questions of interpretation. Correct patient information is crucial for declarations of informed consent.

The main nonconformities enumerated to facilitate consensual codification. In each case, an action is defined: refusal to realize the examination with request of a new sample, request of information or correction, results cancellation, nurse or physician information. A traceability of the curative, corrective and preventive actions is needed. Then, methodology and indicators are proposed to assess nonconformity and to follow the quality improvements. The laboratory information system can be used instead of dedicated software. Tools for the follow-up of nonconformities scores are proposed. Finally, we propose an organization and some tools allowing the management and control of the nonconformities occurring during the pre-examination phase.

Spatial database for the management of "urban geology" geothematic information: the case of Drama City, Greece

NASA Astrophysics Data System (ADS)

Pantelias, Eustathios; Zervakou, Alexandra D.; Tsombos, Panagiotis I.; Nikolakopoulos, Konstantinos G.

2008-10-01

The aggregation of population in big cities leads to the concentration of human activities, economic wealth, over consumption of natural resources and urban growth without planning and sustainable management. As a result, urban societies are exposed to various dangers and threats with economical, social, ecological - environmental impacts on the urban surroundings. Problems associated with urban development are related to their geological conditions and those of their surroundings, e.g. flooding, land subsidence, groundwater pollution, soil contamination, earthquakes, landslides, etc. For these reasons, no sustainable urban planning can be done without geological information support. The first systematic recording, codification and documentation of "urban geology" geothematic information in Greece is implemented by the Institute of Geological and Mineral Exploration (I.G.M.E.) in the frame of project "Collection, codification and documentation of geothematic information for urban and suburban areas in Greece - pilot applications". Through the implementation of this project, all geothematic information derived from geological mapping, geotechnical - geochemical - geophysical research and measurements in four pilot areas of Greece Drama (North Greece), Nafplio & Sparti (Peloponnesus) and Thrakomakedones (Attica) is stored and processed in specially designed geodatabases in GIS environment containing vector and raster data. For the specific GIS application ArcGIS Personal Geodatabase is used. Data is classified in geothematic layers, grouped in geothematic datasets (e.g. Topography, Geology - Tectonics, Submarine Geology, Technical Geology, Hydrogeology, Soils, Radioactive elements, etc) and being processed in order to produced multifunctional geothematic maps. All compiled data constitute the essential base for land use planning and environmental protection in specific urban areas. With the termination of the project the produced geodatabase and other digital data (thematic maps, DEMs) will be available to all, public or private sector, concerning geological environment in urban and suburban areas, being in charge of protection and improvement of natural and human made environment.

Group Violence and Migration Experience among Latin American Youths in Justice Enforcement Centers (Madrid, Spain).

PubMed

Martínez García, José Manuel; Martín López, María Jesús

2015-10-30

Group violence among Latin American immigrant youth has led to ongoing debates in political, legal, and media circles, yet none of those many perspectives has arrived at a solid, empirically supported definition for the phenomenon. This study aims to explore the relationship between the immigrant experience and violent group behavior in youths from Latin America serving prison sentences in Justice Enforcement Centers in the Community of Madrid. Semi-structured interviews were conducted with 19 juveniles, and content analysis was applied to the resulting transcripts, employing Grounded Theory to create an axial codification of intra- and inter-categorical contents, and Delphi panels for quality control. The research team delved into 62 topics, addressing participants' perceptions of the immigrant experience and its effects on five socialization settings (neighborhood, school, family, peer group, and significant other), and each one's relationship to violent behavior. The results led us to believe the young people's immigration experiences had been systematically examined. Their personal and social development was influenced by negative socioeconomic conditions, ineffective parental supervision, maladjustment and conflict at school, and experiences of marginalization and xenophobia. All those conditions favored affiliation with violent groups that provided them instrumental (economic and material), expressive, or affective support.

An Informatics Blueprint for Healthcare Quality Information Systems

PubMed Central

Niland, Joyce C.; Rouse, Layla; Stahl, Douglas C.

2006-01-01

There is a critical gap in our nation's ability to accurately measure and manage the quality of medical care. A robust healthcare quality information system (HQIS) has the potential to address this deficiency through the capture, codification, and analysis of information about patient treatments and related outcomes. Because non-technical issues often present the greatest challenges, this paper provides an overview of these socio-technical issues in building a successful HQIS, including the human, organizational, and knowledge management (KM) perspectives. Through an extensive literature review and direct experience in building a practical HQIS (the National Comprehensive Cancer Network Outcomes Research Database system), we have formulated an “informatics blueprint” to guide the development of such systems. While the blueprint was developed to facilitate healthcare quality information collection, management, analysis, and reporting, the concepts and advice provided may be extensible to the development of other types of clinical research information systems.

Health information management: an introduction to disease classification and coding.

PubMed

Mony, Prem Kumar; Nagaraj, C

2007-01-01

Morbidity and mortality data constitute an important component of a health information system and their coding enables uniform data collation and analysis as well as meaningful comparisons between regions or countries. Strengthening the recording and reporting systems for health monitoring is a basic requirement for an efficient health information management system. Increased advocacy for and awareness of a uniform coding system together with adequate capacity building of physicians, coders and other allied health and information technology personnel would pave the way for a valid and reliable health information management system in India. The core requirements for the implementation of disease coding are: (i) support from national/institutional health administrators, (ii) widespread availability of the ICD-10 material for morbidity and mortality coding; (iii) enhanced human and financial resources; and (iv) optimal use of informatics. We describe the methodology of a disease classification and codification system as also its applications for developing and maintaining an effective health information management system for India.

Forecast Inaccuracies in Power Plant Projects From Project Managers' Perspectives

NASA Astrophysics Data System (ADS)

Sanabria, Orlando

Guided by organizational theory, this phenomenological study explored the factors affecting forecast preparation and inaccuracies during the construction of fossil fuel-fired power plants in the United States. Forecast inaccuracies can create financial stress and uncertain profits during the project construction phase. A combination of purposeful and snowball sampling supported the selection of participants. Twenty project managers with over 15 years of experience in power generation and project experience across the United States were interviewed within a 2-month period. From the inductive codification and descriptive analysis, 5 themes emerged: (a) project monitoring, (b) cost control, (c) management review frequency, (d) factors to achieve a precise forecast, and (e) factors causing forecast inaccuracies. The findings of the study showed the factors necessary to achieve a precise forecast includes a detailed project schedule, accurate labor cost estimates, monthly project reviews and risk assessment, and proper utilization of accounting systems to monitor costs. The primary factors reported as causing forecast inaccuracies were cost overruns by subcontractors, scope gaps, labor cost and availability of labor, and equipment and material cost. Results of this study could improve planning accuracy and the effective use of resources during construction of power plants. The study results could contribute to social change by providing a framework to project managers to lessen forecast inaccuracies, and promote construction of power plants that will generate employment opportunities and economic development.

Algorithms and theory for the design and programming of industrial control systems materialized with PLC's

NASA Astrophysics Data System (ADS)

Montoya Villena, Rafael

According to its title, the general objective of the Thesis consists in developing a clear, simple and systematic methodology for programming type PLC devices. With this aim in mind, we will use the following elements: Codification of all variables types. This section is very important since it allows us working with little information. The necessary rules are given to codify all type of phrases produced in industrial processes. An algorithm that describes process evolution and that has been called process D.F. This is one of the most important contributions, since it will allow us, together with information codification, representing the process evolution in a graphic way and with any design theory used. Theory selection. Evidently, the use of some kind of design method is necessary to obtain logic equations. For this particular case, we will use binodal theory, an ideal theory for wired technologies, since it can obtain highly reduced schemas for relatively simple automatisms, which means a minimum number of components used. User program outline algorithm (D.F.P.). This is another necessary contribution and perhaps the most important one, since logic equations resulting from binodal theory are compatible with process evolution if wired technology is used, whether it is electric, electronic, pneumatic, etc. On the other hand, PLC devices performance characteristics force the program instructions order to validate or not the automatism, as we have proven in different articles and lectures at congresses both national and international. Therefore, we will codify any information concerning the automating process, graphically represent its temporal evolution and, applying binodal theory and D.F.P (previously adapted), succeed in making logic equations compatible with the process to be automated and the device in which they will be implemented (PLC in our case)

Knowledge management in the engineering design environment

NASA Technical Reports Server (NTRS)

Briggs, Hugh C.

2006-01-01

The Aerospace and Defense industry is experiencing an increasing loss of knowledge through workforce reductions associated with business consolidation and retirement of senior personnel. Significant effort is being placed on process definition as part of ISO certification and, more recently, CMMI certification. The process knowledge in these efforts represents the simplest of engineering knowledge and many organizations are trying to get senior engineers to write more significant guidelines, best practices and design manuals. A new generation of design software, known as Product Lifecycle Management systems, has many mechanisms for capturing and deploying a wider variety of engineering knowledge than simple process definitions. These hold the promise of significant improvements through reuse of prior designs, codification of practices in workflows, and placement of detailed how-tos at the point of application.

An Alternative Wearable Tracking System Based on a Low-Power Wide-Area Network.

PubMed

Fernández-Garcia, Raul; Gil, Ignacio

2017-03-14

This work presents an alternative wearable tracking system based on a low-power wide area network. A complete GPS receiver was integrated with a textile substrate, and the latitude and longitude coordinates were sent to the cloud by means of the SIM-less SIGFOX network. To send the coordinates over SIGFOX protocol, a specific codification algorithm was used and a customized UHF antenna on jeans fabric was designed, simulated and tested. Moreover, to guarantee the compliance to international regulations for human body exposure to electromagnetic radiation, the electromagnetic specific absorption rate of this antenna was analyzed. A specific remote server was developed to decode the latitude and longitude coordinates. Once the coordinates have been decoded, the remote server sends this information to the open source data viewer SENTILO to show the location of the sensor node in a map. The functionality of this system has been demonstrated experimentally. The results guarantee the utility and wearability of the proposed tracking system for the development of sensor nodes and point out that it can be a low cost alternative to other commercial products based on GSM networks.

Self-organization of meaning and the reflexive communication of information

PubMed Central

Leydesdorff, Loet; Petersen, Alexander M.; Ivanova, Inga

2017-01-01

Following a suggestion from Warren Weaver, we extend the Shannon model of communication piecemeal into a complex systems model in which communication is differentiated both vertically and horizontally. This model enables us to bridge the divide between Niklas Luhmann’s theory of the self-organization of meaning in communications and empirical research using information theory. First, we distinguish between communication relations and correlations among patterns of relations. The correlations span a vector space in which relations are positioned and can be provided with meaning. Second, positions provide reflexive perspectives. Whereas the different meanings are integrated locally, each instantiation opens global perspectives – ‘horizons of meaning’ – along eigenvectors of the communication matrix. These next-order codifications of meaning can be expected to generate redundancies when interacting in instantiations. Increases in redundancy indicate new options and can be measured as local reduction of prevailing uncertainty (in bits). The systemic generation of new options can be considered as a hallmark of the knowledge-based economy. PMID:28232771

Background Addiction is one of the complicated problems in Iranian young population. The social and cultural dimensions of this social disease are less considered. So considering socio-cultural and environmental resources, this study investigated the substructures of addiction according to the viewpoints of high-school students of Kerman, Iran in 2007-2008. Methods This qualitative study accomplished in ten high schools through a one-day problem finding workshop and continued until data saturation. The resulted terms and phrases were analyzed by content analysis. To assure about the validity and reliability, the outputs reviewed by workshops participants, and classification and codification of the data were executed separately by two experts. Findings A total of 212 students, 45.3% girls and 54.7% boys, participated in the study. The students introduced the followings as the addiction substantial fundaments: lack of knowledge, positive attitude and interpretation of addiction as a value, family or friends' habit, economy status, psycho-personality problems and availability. Rules infirmity or non-implementation of the current rules enforcement, geographical status and addiction as a conspiracy were also observed in students’ statements. Conclusion The positive attitudes and historical roots of addiction along with the process of changing the values caused the growth of drug addiction in young population which could neutralize the security measures, legislations policy and even the knowledge. Therefore, intensification of personal protective factors and culturalization addressed for improving inner layers of values are recommended. PMID:24494110

Voice, (inter-)subjectivity, and real time recurrent interaction

PubMed Central

Cummins, Fred

2014-01-01

Received approaches to a unified phenomenon called “language” are firmly committed to a Cartesian view of distinct unobservable minds. Questioning this commitment leads us to recognize that the boundaries conventionally separating the linguistic from the non-linguistic can appear arbitrary, omitting much that is regularly present during vocal communication. The thesis is put forward that uttering, or voicing, is a much older phenomenon than the formal structures studied by the linguist, and that the voice has found elaborations and codifications in other domains too, such as in systems of ritual and rite. Voice, it is suggested, necessarily gives rise to a temporally bound subjectivity, whether it is in inner speech (Descartes' “cogito”), in conversation, or in the synchronized utterances of collective speech found in prayer, protest, and sports arenas world wide. The notion of a fleeting subjective pole tied to dynamically entwined participants who exert reciprocal influence upon each other in real time provides an insightful way to understand notions of common ground, or socially shared cognition. It suggests that the remarkable capacity to construct a shared world that is so characteristic of Homo sapiens may be grounded in this ability to become dynamically entangled as seen, e.g., in the centrality of joint attention in human interaction. Empirical evidence of dynamic entanglement in joint speaking is found in behavioral and neuroimaging studies. A convergent theoretical vocabulary is now available in the concept of participatory sense-making, leading to the development of a rich scientific agenda liberated from a stifling metaphysics that obscures, rather than illuminates, the means by which we come to inhabit a shared world.

Fast, Parallel and Secure Cryptography Algorithm Using Lorenz's Attractor

NASA Astrophysics Data System (ADS)

Marco, Anderson Gonçalves; Martinez, Alexandre Souto; Bruno, Odemir Martinez

A novel cryptography method based on the Lorenz's attractor chaotic system is presented. The proposed algorithm is secure and fast, making it practical for general use. We introduce the chaotic operation mode, which provides an interaction among the password, message and a chaotic system. It ensures that the algorithm yields a secure codification, even if the nature of the chaotic system is known. The algorithm has been implemented in two versions: one sequential and slow and the other, parallel and fast. Our algorithm assures the integrity of the ciphertext (we know if it has been altered, which is not assured by traditional algorithms) and consequently its authenticity. Numerical experiments are presented, discussed and show the behavior of the method in terms of security and performance. The fast version of the algorithm has a performance comparable to AES, a popular cryptography program used commercially nowadays, but it is more secure, which makes it immediately suitable for general purpose cryptography applications. An internet page has been set up, which enables the readers to test the algorithm and also to try to break into the cipher.

Multipoint entanglement in disordered systems

NASA Astrophysics Data System (ADS)

Magán, Javier M.; Paganelli, Simone; Oganesyan, Vadim

2017-02-01

We develop an approach to characterize excited states of disordered many-body systems using spatially resolved structures of entanglement. We show that the behavior of the mutual information (MI) between two parties of a many-body system can signal a qualitative difference between thermal and localized phases - MI is finite in insulators while it approaches zero in the thermodynamic limit in the ergodic phase. Related quantities, such as the recently introduced Codification Volume (CV), are shown to be suitable to quantify the correlation length of the system. These ideas are illustrated using prototypical non-interacting wavefunctions of localized and extended particles and then applied to characterize states of strongly excited interacting spin chains. We especially focus on evolution of spatial structure of quantum information between high temperature diffusive and many-body localized (MBL) phases believed to exist in these models. We study MI as a function of disorder strength both averaged over the eigenstates and in time-evolved product states drawn from continuously deformed family of initial states realizable experimentally. As expected, spectral and time-evolved averages coincide inside the ergodic phase and differ significantly outside. We also highlight dispersion among the initial states within the localized phase - some of these show considerable generation and delocalization of quantum information.

Tilley, Helen

2010-03-01

Scholars in imperial and science studies have recently begun to examine more systematically the different ways knowledge systems around the world have intersected. This essay concentrates on one aspect of this process, the codification of research into "primitive" or "indigenous" knowledge, especially knowledge that was transmitted orally, and argues that such investigations were a by-product of four interrelated phenomena: the globalization of the sciences themselves, particularly those fields that took the earth and its inhabitants as their object of analysis; the professionalization of anthropology and its growing emphasis on studying other cultures' medical, technical, and natural knowledge; the European push, in the late nineteenth century, toward "global colonialism" and the ethnographic research that accompanied colonial state building; and, finally, colonized and marginalized peoples' challenges to scientific epistemologies and their paradoxical call that scientists study their knowledge systems more carefully. These phenomena came together on a global scale in the decades surrounding the turn of the twentieth century to produce a subgenre of research within the sciences, here labeled "vernacular science," focused explicitly on "native" knowledge.

This Djibouti Act codifies a system of family allowances for workers referred to in Article 1 of the Act instituting the Labour Code. The system consists of 3 benefits: 1) a marriage allowance, 2) family allowances, and 3) benefits for salaried pregnant women. The marriage allowance is to be paid monthly from the beginning of the marriage and is payable for the 1st marriage only. The family allowance is to be paid monthly for each of the 1st 6 children under the care of the worker until they reach the age of 15. It is to be paid to the person under whose actual and permanent care the child remains and may be paid to salaried women workers if they are widowed, divorced, or single. Pregnancy benefits in the amount of half the worker's salary are to be paid to salaried women workers for 14 weeks (8 weeks before delivery and 6 weeks after) and for an additional 3 weeks in the case of certified illness resulting from pregnancy or delivery. The amounts of the marriage and family allowances are to be set by an Order of the Council of Ministers.

Anatomy of deception: a behavioral contingency analysis.

PubMed

Mechner, Francis

2010-05-01

Deception, a basic and pervasive biological phenomenon, takes many forms, variously referred to as mimicry, trickery, seduction, pretense, feigning, masquerading, impersonation, distraction, or false promises, and these share certain common distinguishing behavioral elements that permit them to be classified into categories. A symbolic language for the codification and analysis of behavioral contingencies shows that all instances of deception are based on a misperception, misprediction, non-perception, or non-prediction by the deceived party, and can be further categorized based on features of the contingencies that define them. Instances of particular interest are those in which a deceiving party predicts (and in that sense "intends") the deception. In those instances, the effect of the deception is usually to the deceiving party's benefit and to the deceived party's detriment. In economics, finance, business, military operations, public affairs, education, and everyday social interaction, deception takes numerous forms. Special forms, usually involving obfuscation, concealment, counterfeiting, and misrepresentation, occur in certain prevalent types of property transfer, including securitization, the creation of derivatives, and various types of Ponzi schemes. Such property transfers tend to be driven by opportunities for deception. They all involve blurring and clouding of the contingencies that defined the transferred properties, thus permitting their obfuscation. Copyright (c) 2009 Elsevier B.V. All rights reserved.

Practicing Research Ethics: Private-Sector Physicians & Pharmaceutical Clinical Trials

PubMed Central

2008-01-01

This paper focuses on constructions of research ethics by primary care physicians in the USA as they engage in contract research for the pharmaceutical industry. Drawing first upon historical studies of physicians as investigators and then upon 12 months of qualitative fieldwork in the South Western US, this paper analyzes the shifting, contextualized ethics that shape physicians’ relationships with patients/subjects and pharmaceutical companies. Just as physicians followed professional codes of ethics prior to the codification of acceptable research conduct in the 1980s, physicians today continue to develop tacit systems of research ethics. This paper argues that private-sector physicians primarily conceptualize their ethical conduct in relation to the pharmaceutical companies hiring them, not to human subjects they enroll in clinical trials. This is not to say that these physicians do not follow the formal U.S. regulation to protect human subjects, but rather that their financial relationships with the pharmaceutical industry have a greater influence on their identities as researchers and on their constructions of their ethical responsibilities.

Menarche and menstruation: a review of the literature.

PubMed

Swenson, I; Havens, B

1987-01-01

Puberty initiation rites heralding menarche are common across cultures. Paige (1973) reflected that societies with the highest levels of social rigidity and male solidarity also have the strongest codification of menstrual taboos. This may reflect a need to maintain clear sex roles, often by controlling women and their fertility. Social and cultural factors impact on adjustment to menses and have an effect on the early menarcheal experience. Certain common features, however, were observed in that most girls reported their mothers as a principal source of information and received some limited education about menses in school with frequent emphasis on hygienic aspects of menstruation. A more positive attitude toward menses can be achieved if girls are physically and emotionally prepared. The most current evaluation of educational materials on menses dates back to 1975 and reveals a preponderance of emphasis on hygiene to the exclusion of issues of emotional and psychological development. Women perceive themselves as being very knowledgeable but cannot accurately answer physiological questions. A content analysis of advertisements for sanitary products and medications for the relief of menstrual symptoms in a popular teen magazine indicated that advertisements conveyed the image that hygienic aspects of migration could be dealt with effectively. There were no significant relationships between reported incidence of menstrual symptoms and adequacy of preparation for menarche. Nurses involved in the planning or implementing of educational programs for girls regarding the menarche should be sensitive to the adolescent's desire for control of the learning environment and a need for selective sharing of the event. Strategies for coping with the "inconvenience" may be usefully developed with the girls as a part of the learning situation.

We experimentally demonstrate Fresnel holograms able to produce multifocal irradiance patterns with micrometric spatial resolution. These holograms are assessed from the coherent sum of multiple Fresnel lenses. The utilized encoded technique guarantees full control over the reconstructed irradiance patterns due to an optimal codification of the amplitude and phase information of the resulting complex field. From a practical point of view, a phase-only spatial light modulator is used in a couple of experiments addressed to obtain two- and three-dimensional distributions of focal points to excite both linear and non-linear optical phenomena.

Along with the growing of the aging population and the necessity of efficient wellness systems, there is a mounting demand for new technological solutions able to support remote and proactive healthcare. An answer to this need could be provided by the joint use of the emerging Radio Frequency Identification (RFID) technologies and advanced software choices. This paper presents a proposal for a context-aware infrastructure for ubiquitous and pervasive monitoring of heterogeneous healthcare-related scenarios, fed by RFID-based wireless sensors nodes. The software framework is based on a general purpose architecture exploiting three key implementation choices: ontology representation, multi-agent paradigm and rule-based logic. From the hardware point of view, the sensing and gathering of context-data is demanded to a new Enhanced RFID Sensor-Tag. This new device, de facto, makes possible the easy integration between RFID and generic sensors, guaranteeing flexibility and preserving the benefits in terms of simplicity of use and low cost of UHF RFID technology. The system is very efficient and versatile and its customization to new scenarios requires a very reduced effort, substantially limited to the update/extension of the ontology codification. Its effectiveness is demonstrated by reporting both customization effort and performance results obtained from validation in two different healthcare monitoring contexts.

Our aim was to identify the level of knowledge of surgical health-area specialists in Cancún, Quintana Roo, Mexico, from the personal productivity database. We carried out an investigation of 37 surgical specialists: 24 belonged to the Mexican Social Security Institute (IMSS), while 13 belonged to the Mexican Health Secretariat (SSA). In our research, we found that 61% of surgical health-area specialist physicians were familiar with some aspects of the institutional surgical registry, including the following: 54% knew of the existence of a personal registry of surgeries carried out, and 43% keep a record of their personal activities. From the latter percentage, 69% of surgical health-area specialist physicians mentioned keeping their records manually, while 44% used the computer. Results of the research suggest that these physicians would like to have some kind of record of the surgeries carried out by each. An important percentage of these specialists do not keep a personal record on a database; due to this lack of knowledge, we obtain incorrect information in institutional records of the reality of what is actually done. We consider it important to inform surgical specialists concerning the existence of personal institutional records in database form or even of record done manually, as well as correct terminology for the International Codification (CIE-9 & 10). We inform here of the need to encourage a culture in records and databases in the formative stage of surgeon specialists.

INTRODUCTION: According to the research mission of the librarianship and information sciences field, it is necessary to have the ability to communicate constructively between the user of the information and information in these students, and it appears more important in medical librarianship and information sciences because of the need for quick access to information for clinicians. Considering the role of spiritual intelligence in capability to establish effective and balanced communication makes it important to study this variable in librarianship and information students. One of the main factors that can affect the results of any research is conceptual model of measure variables. Accordingly, the purpose of this study was codification of spiritual intelligence measurement model. METHODS: This correlational study was conducted through structural equation model, and 270 students were opted from library and medical information students of nationwide medical universities by simple random sampling and responded to the King spiritual intelligence questionnaire (2008). Initially, based on the data, the model parameters were estimated using maximum likelihood method; then, spiritual intelligence measurement model was tested by fit indices. Data analysis was performed by Smart-Partial Least Squares software. RESULTS: Preliminary results showed that due to the positive indicators of predictive association and t-test results for spiritual intelligence parameters, the King measurement model has the acceptable fit and internal correlation of the questionnaire items was significant. Composite reliability and Cronbach's alpha of parameters indicated high reliability of spiritual intelligence model. CONCLUSIONS: The spiritual intelligence measurement model was evaluated, and results showed that the model has a good fit, so it is recommended that domestic researchers use this questionnaire to assess spiritual intelligence.

Characteristics of DC electric fields in transient plasma sheet events

We take an advantage of five different DC electric field measurements in the plasma sheet available from the EFW double probe experiment, EDI electron drift instrument, CODIF and HIA ion spectrometers, and PEACE electron spectrometer on the four Cluster spacecraft. The calibrated observations of the three spectrometers are used to determine the proton and electron velocity moments. The velocity moments can be used to estimate the proton and electron drift velocity and furthermore the DC electric field, assuming that the electron and proton velocity perpendicular to the magnetic field is dominated by the ExB drift motion. Naturally when ions and electrons do not perform a proper drift motion, which can happen in the plasma sheet, the estimated DC electric field from ion and electron motion is not correct. However, surprisingly often the DC electric fields estimated from electron and ion motions are identical suggesting that this field is a real DC electric field around the measurement point. As the measurement techniques are so different, it is quite plausible that when two different measurements yield the same DC electric field, it is the correct field. All five measurements of the DC electric field are usually not simultaneously available, especially on Cluster 2 where CODIF and HIA are not operational, or on Cluster 4 where EDI is off. In this presentation we investigate DC electric field in various transient plasma sheet events such as dipolarization events and BBF's and how the five measurements agree or disagree. There are plenty of important issues that are considered, e.g., (1) what kind of DC electric fields exist in such events and what are their spatial scales, (2) do electrons and ions perform ExB drift motions in these events, and (3) how well the instruments have been calibrated.

The Act of 6 November 2008 on Patients' Rights and the Commissioner for Patients' Rights collect and safeguard patients' basic rights as well as provide, for the first time in Poland, an original concept for patients' collective rights. In addition, the new Act stipulates the specific mechanism for protecting patients' rights by the newly established body called the Commissioner for Patients' Rights. Polish reform of medical law will undoubtedly contribute to the expected ratification of the Convention on Human Rights and Biomedicine. However, the nature of codified rights is relatively abstract, and the Act cannot be read without reference to legislation related to physicians and health care institutions.

Financing family planning services: is categorical legislation still needed?

PubMed

Mcfarlane, D R; Meier, K J

1991-01-01

Federal and state funds have provided for family planning services in American since the 1960s. Since 1976, services have been funded principally through federal statutes Title X of the Public Health Service Act and Titles V, XIX, and XX of the Social Security Act as well as various state appropriations. While these statutes aim to ensure that women of lower socioeconomic status enjoy access to reproductive health care services, levels of public expenditure in this area vary widely among states. In 1987, public family planning expenditures/woman at risk ranged from $60.16 in Wisconsin to $9.41 in Florida. Within this range of expenditures, the relative importance of each funding source per state varies widely. States with the most robust Title XIX programs, Medicaid, however, have highest per woman family planning expenditures. Upon reviewing the complement of public funding sources and how they are spent at the state level, the authors argue that categorical legislation is still needed to protect access to contraceptive services in America. In particular, of funds from supporting statues, Medicaid is distributed most equitable across the country. These funds paid for 36% of all public outlays for family planning in 1987. Without categorical legislation, however, Medicaid is insufficient to maintain the national family planning effort; the 1987 contribution of $10.49/woman at risk of unwanted pregnancy was insufficient to provide minimum services. Title X requires grantees to follow regulations which ensure state uniformity of quality and service distribution; submission of annual 5-year plans to Congress on how family planning goals will be achieved; and also authorizes monies for training and research. Despite political attacks, family planning funding must remain separate from maternal and child health programs. Such independence will keep these services politically visible; allow use of the more extensive family planning delivery system; catalyze states to spend other monies on family planning; and fuel innovations in service delivery, client education, and new contraceptive technologies. Title X should even be reauthorized under more precise mandates and include a national data collection system, consideration of the shortage of clinicians, and codification of 1981 guidelines reversed by the gag rule.

Regime change: re-visiting the 1961 Single Convention on Narcotic Drugs.

PubMed

Bewley-Taylor, David; Jelsma, Martin

2012-01-01

March 2011 marked the 50th anniversary of the Single Convention on Narcotic Drugs. This legal instrument, the bedrock of the current United Nations based global drug control regime, is often viewed as merely a consolidating treaty bringing together the multilateral drug control agreements that preceded it; an erroneous position that does little to provide historical context for contemporary discussions surrounding revision of the international treaty system. This article applies both historical and international relations perspectives to revisit the development of the Convention. Framing discussion within the context of regime theory, a critique of the foundational pre-1961 treaties is followed by detailed content analysis of the official records of the United Nations conference for the adoption of a Single Convention on Narcotic Drugs and, mindful of later treaties, an examination of the treaty's status as a 'single' convention. The Single Convention on Narcotic Drugs represents a significant break with the regulative focus of the preceding multilateral treaties; a shift towards a more prohibitive outlook that within international relations terms can be regarded as a change of regime rather than the straightforward codification of earlier instruments. In this respect, the article highlights the abolition of drug use that for centuries had been embedded in the social, cultural and religious traditions of many non-Western states. Further, although often-overlooked, the Convention has failed in its aim of being the 'single' instrument within international drug control. The supplementing treaties developed in later years and under different socio-economic and political circumstances have resulted in significant inconsistencies within the control regime. Having established that a shift in normative focus has taken place in the past, the article concludes that it is timely for the international community to revisit the Single Convention on Narcotic Drugs with a view to correcting past errors and inconsistencies within the regime, particularly those relating to Scheduling and traditional drug use.

A comparative study between control strategies for a solar sailcraft in an Earth-Mars transfer

Mainenti-Lopes, I.; Souza, L. C. Gadelha; De Sousa, Fabiano. L.

2016-10-01

The goal of this work was a comparative study of solar sail trajectory optimization using different control strategies. Solar sailcraft is propulsion system with great interest in space engineering, since it uses solar radiation to propulsion. So there is no need for propellant to be used, thus it can remains active throughout the entire transfer maneuver. This type of propulsion system opens the possibility to reduce the cost of exploration missions in the solar system. In its simplest configuration, a Flat Solar Sail (FSS) consists of a large and thin structure generally composed by a film fixed to flexible rods. The performance of these vehicles depends largely on the sails attitude relative to the Sun. Using a FSS as propulsion, an Earth-Mars transfer optimization problem was tackled by the algorithms GEOreal1 and GEOreal2 (Generalized Extremal Optimization with real codification). Those algorithms are Evolutionary Algorithms (AE) based on the theory of Self-Organized Criticality. They were used to optimize the FSS attitude angle so it could reach Mars orbit in minimum time. It was considered that the FSS could perform up to ten attitude maneuvers during orbital transfer. Moreover, the time between maneuvers can be different. So, the algorithms had to optimize an objective function with 20 design variables. The results obtained in this work were compared with previously results that considered constant values of time between maneuvers.

Structure/activity relationships for biodegradability and their role in environmental assessment

DOE Office of Scientific and Technical Information (OSTI.GOV)

Boethling, R.S.

1994-12-31

Assessment of biodegradability is an important part of the review process for both new and existing chemicals under the Toxic Substances Control Act. It is often necessary to estimate biodegradability because experimental data are unavailable. Structure/biodegradability relationships (SBR) are a means to this end. Quantitative SBR have been developed, but this approach has not been very useful because they apply only to a few narrowly defined classes of chemicals. In response to the need for more widely applicable methods, multivariate analysis has been used to develop biodegradability classification models. For example, recent efforts have produced four new models. Two calculatemore » the probability of rapid biodegradation and can be used for classification; the other two models allow semi-quantitative estimation of primary and ultimate biodegradation rates. All are based on multiple regressions against 36 preselected substructures plus molecular weight. Such efforts have been fairly successful by statistical criteria, but in general are hampered by a lack of large and consistent datasets. Knowledge-based expert systems may represent the next step in the evolution of SBR. In principle such systems need not be as severely limited by imperfect datasets. However, the codification of expert knowledge and reasoning is a critical prerequisite. Results of knowledge acquisition exercises and modeling based on them will also be described.« less

The application of tandem MALDI-TOF MS screening with 16S rRNA gene sequencing of selected isolates has been demonstrated to be an excellent approach for retrieving novelty from large-scale culturing. The application of such methodologies in different hypersaline samples allowed the isolation of the culture-recalcitrant Salinibacter ruber second phylotype (EHB-2) for the first time, as well as a new species recently isolated from the Argentinian Altiplano hypersaline lakes. In this study, the genome sequences of the different species of the phylum Rhodothermaeota were compared and the genetic repertoire along the evolutionary gradient was analyzed together with each intraspecific variability. Altogether, the results indicated an open pan-genome for the family Salinibacteraceae, as well as the codification of relevant traits such as diverse rhodopsin genes, CRISPR-Cas systems and spacers, and one T6SS secretion system that could give ecological advantages to an EHB-2 isolate. For the new Salinibacter species, we propose the name Salinibacter altiplanensis sp. nov. (the designated type strain is AN15 T =CECT 9105 T =IBRC-M 11031 T ). Copyright © 2018 Elsevier GmbH.

Bio-inspired spiking neural network for nonlinear systems control.

PubMed

Pérez, Javier; Cabrera, Juan A; Castillo, Juan J; Velasco, Juan M

2018-08-01

Spiking neural networks (SNN) are the third generation of artificial neural networks. SNN are the closest approximation to biological neural networks. SNNs make use of temporal spike trains to command inputs and outputs, allowing a faster and more complex computation. As demonstrated by biological organisms, they are a potentially good approach to designing controllers for highly nonlinear dynamic systems in which the performance of controllers developed by conventional techniques is not satisfactory or difficult to implement. SNN-based controllers exploit their ability for online learning and self-adaptation to evolve when transferred from simulations to the real world. SNN's inherent binary and temporary way of information codification facilitates their hardware implementation compared to analog neurons. Biological neural networks often require a lower number of neurons compared to other controllers based on artificial neural networks. In this work, these neuronal systems are imitated to perform the control of non-linear dynamic systems. For this purpose, a control structure based on spiking neural networks has been designed. Particular attention has been paid to optimizing the structure and size of the neural network. The proposed structure is able to control dynamic systems with a reduced number of neurons and connections. A supervised learning process using evolutionary algorithms has been carried out to perform controller training. The efficiency of the proposed network has been verified in two examples of dynamic systems control. Simulations show that the proposed control based on SNN exhibits superior performance compared to other approaches based on Neural Networks and SNNs. Copyright © 2018 Elsevier Ltd.

2010-01-01

This article examines 18th-century European warfare, tracing the first formal codifications of conventions of war, frequently introduced by military physicians and initially regarding the treatment of the sick and wounded. It outlines to what extent these conventions were followed in practice, particularly in the challenging environment of American irregular warfare, with a focus on the most well-known incident of "biological warfare" in the period: the deliberate spread of smallpox by British officers among Amerindians in 1763. More broadly, it demonstrates that the history of military medicine provides a fruitful method with which to uncover assumptions about the ethics of war.

This study aimed to understand the meaning of Nursing Care Systematization (NCS) for multiprofessional health team professionals based on the relationships, interactions and associations of Complex thought. This qualitative study uses Grounded Theory as a methodological reference framework. Data were obtained through interviews with three sample groups, totaling 15 professionals from different institutions. Simultaneous data codification and analysis identified the central theme: 'Glimpsing nursing care systematization as an interactive and multidimensional phenomenon' and the respective reference model. NCS appoints, in addition to interactivity and professional complementarity, the importance of dialog and connection between the academy, health practices and regulatory offices, based on new reference frameworks for the organization of health practices.

We show an accurate procedure to obtain a Fourier transform (FT) with no dc term using a commercial twisted-nematic liquid-crystal display. We focus on the application to holographic storage of binary data pages, where a drastic decrease of the dc term in the FT is highly desirable. Two different codification schemes are considered: binary pi radians phase modulation and hybrid ternary modulation. Any deviation in the values of the amplitude and phase shift generates the appearance of a strong dc term. Experimental results confirm that the calculated configurations provide a FT with no dc term, thus showing the effectiveness of the proposal.

Mobilising culture against domestic violence in migrant and ethnic communities: practitioner perspectives from Aotearoa/New Zealand.

2017-07-01

Studies on domestic violence in ethnic minority communities highlight that social norms, family structures and cultural practices are among the key triggers of violence against women. Not surprisingly, most anti-violence interventions in these communities aim to redeem women from the oppressive features of these cultures. More recently, however, emergent scholarship advocates mobilising, rather than erasing, culture within existing anti-violence strategies. This paper explores the nature of culturally informed interventions used by front-line workers. It presents the findings of a small-scale qualitative study in Aotearoa/New Zealand, where around 13% of the population are currently deemed to be from minority ethnic communities. Interviews and one focus group were conducted with nine practitioners - including social workers, counsellors and the police - in Hamilton, Aotearoa in 2013-2014. Based on thematic analysis, the paper identifies two core strands: (a) the distinctive profile of ethnic violence and (b) the strategies that mobilise culture in anti-violence interventions. Specifically within the former strand, it was found that violence in the ethnic community was distinctive for the following reasons: the heightened sense of stigma surrounding disclosure and the consequent silence by women who suffer from it; the lack of trust in authority; and the fear of conventional safety plans necessitating longer time periods for rapport-building. Among the strategies that mobilise culture, the study found that practitioners used a family approach; engaged men in their interventions, at times reinforcing gendered roles; utilised micro-interventions; and deployed cultural tropes, especially around spirituality, as a strategy. The conclusion points to the gap between interventions that challenge and mobilise cultures. While anecdotally, the latter are perceived to be relevant and effective in anti-violence interventions, there is need for a fuller assessment and better codification of these strategies within the training of practitioners who work in these communities. © 2017 John Wiley & Sons Ltd.

Policy experimentation and innovation as a response to complexity in China's management of health reforms.

PubMed

Husain, Lewis

2017-08-03

There are increasing criticisms of dominant models for scaling up health systems in developing countries and a recognition that approaches are needed that better take into account the complexity of health interventions. Since Reform and Opening in the late 1970s, Chinese government has managed complex, rapid and intersecting reforms across many policy areas. As with reforms in other policy areas, reform of the health system has been through a process of trial and error. There is increasing understanding of the importance of policy experimentation and innovation in many of China's reforms; this article argues that these processes have been important in rebuilding China's health system. While China's current system still has many problems, progress is being made in developing a functioning system able to ensure broad population access. The article analyses Chinese thinking on policy experimentation and innovation and their use in management of complex reforms. It argues that China's management of reform allows space for policy tailoring and innovation by sub-national governments under a broad agreement over the ends of reform, and that shared understandings of policy innovation, alongside informational infrastructures for the systemic propagation and codification of useful practices, provide a framework for managing change in complex environments and under conditions of uncertainty in which 'what works' is not knowable in advance. The article situates China's use of experimentation and innovation in management of health system reform in relation to recent literature which applies complex systems thinking to global health, and concludes that there are lessons to be learnt from China's approaches to managing complexity in development of health systems for the benefit of the poor.

First simultaneous detection of terrestrial ionospheric molecular ions in the Earth's inner magnetosphere and at the Moon

Heavy molecular ions escaping from a planetary atmosphere can contribute to the long-term evolution of its composition. The ARTEMIS (Acceleration, Reconnection, Turbulence, and Electrodynamics of the Moon's Interaction with the Sun) spacecraft has recently observed outflowing molecular ions at lunar distances in the terrestrial magnetotail (Poppe et al., 2016). Backward particle tracing indicated that these ions should originate from the terrestrial inner magnetosphere. Here we have examined Cluster data acquired by the CIS-CODIF (Cluster Ion Spectrometry-Composition Distribution Function) ion mass spectrometer, obtained in the terrestrial magnetosphere. An event was selected where the orbital conditions were favourable and the Cluster spacecraft were in the high-latitude inner magnetosphere a few hours before the ARTEMIS molecular ion detection. Analysis shows that the CIS-CODIF instrument detected a series of energetic ion species, including not only O+ but also a group of molecular ions around 30 amu. Given the 5-7 m/Δm mass resolution of the instrument, these could include N2+, NO+, or O2+. These ions were detected by Cluster about 14 hours before the ARTEMIS observation in the lunar environment, a time which is compatible with the transfer to lunar distances. The event was during an active period followed by a northward rotation of the IMF. Although energetic heavy molecular ions have been detected in the storm time magnetosphere in the past (e.g. Klecker et al., 1986; Christon et al., 1994), this event constitutes the first coordinated observation in the Earth's inner magnetosphere and at the Moon. Additional events of coordinated outflowing molecular ion observations are currently under analysis. Future missions, as the proposed ESCAPE mission, should investigate in detail the mechanisms of molecular ion acceleration and escape, their link to the solar and magnetospheric activity, and their role in the magnetospheric dynamics and in the long-term evolution of the atmospheric composition.

The increasing number of samples from the biomedical genetic studies and the number of centers participating in the same involves increasing risk of mistakes in the different sample handling stages. We have evaluated the usefulness of the amelogenin test for quality control in sample identification. Amelogenin test (frequently used in forensics) was undertaken on 1224 individuals participating in a biomedical study. Concordance between referred sex in the database and amelogenin test was estimated. Additional sex-error genetic detecting systems were developed. The overall concordance rate was 99.84% (1222/1224). Two samples showed a female amelogenin test outcome, being codified as males in the database. The first, after checking sex-specific biochemical and clinical profile data was found to be due to a codification error in the database. In the second, after checking the database, no apparent error was discovered because a correct male profile was found. False negatives in amelogenin male sex determination were discarded by additional tests, and feminine sex was confirmed. A sample labeling error was revealed after a new DNA extraction. The amelogenin test is a useful quality control tool for detecting sex-identification errors in large genomic studies, and can contribute to increase its validity.

To analyse marketing techniques used in television advertisements of food and drinks (AFDs) directed to children, and their nutritional quality. This is a cross-sectional study of television AFDs directed to children in Spain over 7 days in 2012. Primary appeal, persuasive and nutritional marketing techniques, and links to Internet were registered. The foods were classified according to their nutritional quality using an international codification system and the UK nutrient profile model. Frequency of AFDs using marketing techniques and percentages for unhealthy products were calculated. Taste and fun were the main primary appeals used. Persuasive and nutritional marketing techniques and links to Internet were used in 61%, 68.5% and 65.2% of AFDs, respectively. These techniques were more common during weekdays, enhanced protection time slots and on channels with particular appeal to children. More than two-thirds of AFDs using these techniques were for unhealthy products, reaching 96.2% of AFDs with premium offers and gifts. There is an extensive use of marketing techniques in television AFDs directed to children in Spain. Most products advertised were unhealthy, so stronger governmental regulations are required.

BIRAM: a content-based image retrieval framework for medical images

2006-03-01

In the medical field, digital images are becoming more and more important for diagnostics and therapy of the patients. At the same time, the development of new technologies has increased the amount of image data produced in a hospital. This creates a demand for access methods that offer more than text-based queries for retrieval of the information. In this paper is proposed a framework for the retrieval of medical images that allows the use of different algorithms for the search of medical images by similarity. The framework also enables the search for textual information from an associated medical report and DICOM header information. The proposed system can be used for support of clinical decision making and is intended to be integrated with an open source picture, archiving and communication systems (PACS). The BIRAM has the following advantages: (i) Can receive several types of algorithms for image similarity search; (ii) Allows the codification of the report according to a medical dictionary, improving the indexing of the information and retrieval; (iii) The algorithms can be selectively applied to images with the appropriated characteristics, for instance, only in magnetic resonance images. The framework was implemented in Java language using a MS Access 97 database. The proposed framework can still be improved, by the use of regions of interest (ROI), indexing with slim-trees and integration with a PACS Server.

Water is key to sustainable development especially in semi-arid regions in which the main source of water provision is groundwater. Water has value from a social, economic and environmental perspective and is required to be managed within a sound, integrated socio-economic and environmental framework. Mashhad, the second big city in Iran, has been faced with rapid growth rates of population and economic activities. The groundwater in Mashhad basin has been overexploited to meet the increasing trend of water demand during the past 20 years. Consequently, the region has faced with water scarcity and water quality problems which originates from inefficient use and poor management. To tackle the water issue on a durable basis, within the economic, ecological, and political constraints (i.e. the integrated water resources management, IWRM concept), a Non-Governmental Organization (NGO), named as Mashhad Wise Water Forum (MWWF), has been established in 2013 that encompasses contribution of experts from academia, industry, and governmental policy-makers. The MWWF considers the UN-Water IWRM spiral conceptual model (which contains four stages: Recognizing and identifying; Conceptualizing; Coordinating and planning; Implementing, Monitoring and Evaluating) by implicating participatory water management (water users' involvement) methods in Mashhad basin. Furthermore, the MWWF has planned to look at all dimensions of water crisis (i.e. physical, economic, policy and institutional) particularly institutional dimension by gathering all stockholders, beneficiaries and experts in different parts of water policy making in Mashhad basin. The MWWF vision for Mashhad basin is achieving to sustainable equilibrium of water resources and consumptions in the basin by the prospect to 2040 year. So far, the MWWF has tried to understand and deal with regional diversity in legal systems as well as conflicts between private interests and public welfare in water allocation and management. At the moment, the key achievement of MWWF is "the codification of a strategic guideline for sustainable equilibrium of water resources and consumptions" in the basin, which has been prepared by cooperating of more than 4800 people per hour work. In this paper the procedure that the MWWF has passed is outlined.

Full-color stereoscopic single-pixel camera based on DMD technology

Imaging systems based on microstructured illumination and single-pixel detection offer several advantages over conventional imaging techniques. They are an effective method for imaging through scattering media even in the dynamic case. They work efficiently under low light levels, and the simplicity of the detector makes it easy to design imaging systems working out of the visible spectrum and to acquire multidimensional information. In particular, several approaches have been proposed to record 3D information. The technique is based on sampling the object with a sequence of microstructured light patterns codified onto a programmable spatial light modulator while light intensity is measured with a single-pixel detector. The image is retrieved computationally from the photocurrent fluctuations provided by the detector. In this contribution we describe an optical system able to produce full-color stereoscopic images by using few and simple optoelectronic components. In our setup we use an off-the-shelf digital light projector (DLP) based on a digital micromirror device (DMD) to generate the light patterns. To capture the color of the scene we take advantage of the codification procedure used by the DLP for color video projection. To record stereoscopic views we use a 90° beam splitter and two mirrors, allowing us two project the patterns form two different viewpoints. By using a single monochromatic photodiode we obtain a pair of color images that can be used as input in a 3-D display. To reduce the time we need to project the patterns we use a compressive sampling algorithm. Experimental results are shown.

Sudden appearance of sub-keV structured ions in the inner magnetosphere within one hour: drift simulation

NASA Astrophysics Data System (ADS)

Yamauchi, Masatoshi; Ebihara, Yusuke; Dandouras, Iannis; Nilsson, Hans

2014-05-01

Energy-latitude dispersed structured sub-keV ions in the inner magnetosphere drifts very slowly in the noon-to-afternoon sectors because the eastward corotation and the westward magnetic drift balances to each other there. However, majority of Cluster ion observation by the Cluster Ion Spectrometry (CIS) COmposition DIstribution Function (CODIF) instrument during 2001-2006 showed significant development or intensification (by more than factor of 3) within 1-2 h in that sector during the Cluster perigee traversals that quickly scans latitudinal structure at a fixed local time (Yamauchi et al., 2013). The frequent observations of significant inbound-outbound differences in the wedge-like dispersed ions by Cluster indicates either new injections or high eastward drift velocity even in the afternoon sector. To examine the former possibility, i.e., whether such sudden appearances in the dayside can be explained by the drift motion of ions that are formed during substorm-related injections, we numerically simulated two such examples, one at noon (8 September 2002) and the other in the afternoon (9 July 2001), based on the same ion drift simulation model that has successfully reproduced the ion pattern of an inbound-outbound symmetric event at 5 MLT observed by the Cluster CIS/CODIF instrument. The model uses backward phase-space mapping to a boundary at the nightside 8 Earth radii and forward numerical simulation using re-constructed distribution function at that boundary. For both examples, the ion drift model with finite duration (limited to 1-2 hours) of proton source in the nightside can explain the observed large inbound-outbound differences in the sub-keV proton population without any new sources. Ion drift motion is thus able to cause rapid changes of complicated ion populations, at remote places from the source long time after the substorm activities, although this result does not eliminate the possibility of having independent ionospheric sources.

The objective was to provide a synthesis of the results of the research and discourse lines on main dimensions of patient-centered care in the context of chronic disease management in family medicine, building on Stewart et al.'s model. We developed search strategies for the Medline, Embase, and Cochrane databases, from 1980 to April 2009. All articles addressing patient-centered care in the context of chronic disease management in family medicine were included. A thematic analysis was performed using mixed codification, based on Stewart's model of patient-centered care. Thirty-two articles were included. Six major themes emerged: (1) starting from the patient's situation; (2) legitimizing the illness experience; (3) acknowledging the patient's expertise; (4) offering realistic hope; (5) developing an ongoing partnership; (6) providing advocacy for the patient in the health care system. The context of chronic disease management brings forward new dimensions of patient-centered care such as legitimizing the illness experience, acknowledging patient expertise, offering hope and providing advocacy. Chronic disease management calls for the adaptation of the family physician's role to patients' fluctuating needs. Literature also suggests the involvement of the family physician in care transitions as a component of patient-centered care. Crown Copyright © 2012. Published by Elsevier Ireland Ltd.

Dry eye disease is one of the most common public health problems in the field of ophthalmology that causes decreased physical, psychological, social and occupational functioning, and interferes with daily activities like reading, driving, computer work and watching TV. The effect of this disease on quality of life is similar to severe migraine and angina. In addition, the severity of the disease is closely related to depression. Outbreaks are increasing with the use of contact lenses and refractive surgery such as LASIK. The purpose of this paper is to assess the causes of dry eye and its prevention by the principles of hygiene. In this review study, traditional medicine resources like Al canon fil tibb, Sharh-al-Al Asbab and Exir-e-azam have been studied with engine motors such as Google Scholar and PubMed. From the perspective of Iranian traditional medicine, the principles of maintaining health include air, food and drink, exercise and rest, sleep and wakefulness, mental state, retention of essential materials and depletion of wastes from the body. Proper performance of each principle is useful for the prevention of disease in different organs, including the eyes. Recommendations for the prevention or treatment of dry eye disease include the prevention of dryness in the eye or the entire body. In addition, the stomach and brain are important to eye health. Accordingly, one of the most effective managements of dry eye disease is avoiding foods that affect the eye in this way; for example garlic and onion. Maintaining eye health is related to aspects of physical and mental health of the whole body. Therefore, codification of an integrated plan that contains eating and sleeping patterns, exercise, general clearing, eye clearing, and mental health is essential for treating dry eye disease.

The relationship between physics and mathematics is reviewed upgrading the common in physics classes' perspective of mathematics as a toolkit for physics. The nature of the physics-mathematics relationship is considered along a certain historical path. The triadic hierarchical structure of discipline-culture helps to identify different ways in which mathematics is used in physics and to appreciate its contribution, to recognize the difference between mathematics and physics as disciplines in approaches, values, methods, and forms. We mentioned certain forms of mathematical knowledge important for physics but often missing in school curricula. The geometrical mode of codification of mathematical knowledge is compared with the analytical one in context of teaching school physics and mathematics; their complementarity is exemplified. Teaching may adopt the examples facilitating the claims of the study to reach science literacy and meaningful learning.

Error correction in short time steps during the application of quantum gates

Castro, L.A. de, E-mail: leonardo.castro@usp.br; Napolitano, R.D.J.

We propose a modification of the standard quantum error-correction method to enable the correction of errors that occur due to the interaction with a noisy environment during quantum gates without modifying the codification used for memory qubits. Using a perturbation treatment of the noise that allows us to separate it from the ideal evolution of the quantum gate, we demonstrate that in certain cases it is necessary to divide the logical operation in short time steps intercalated by correction procedures. A prescription of how these gates can be constructed is provided, as well as a proof that, even for themore » cases when the division of the quantum gate in short time steps is not necessary, this method may be advantageous for reducing the total duration of the computation.« less

Harnessing the Interaction Continuum for Subtle Assisted Living

2012-01-01

People interact with each other in many levels of attention, intention and meaning. This Interaction Continuum is used daily to deal with different contexts, adapting the interaction to communication needs and available resources. Nevertheless, computer-supported interaction has mainly focused on the most direct, explicit and intrusive types of human to human Interaction such as phone calls, emails, or video conferences. This paper presents the results of exploring and exploiting the potentials of undemanding interaction mechanisms, paying special attention to subtle communication and background interaction. As we argue the benefits of this type of interaction for people with special needs, we present a theoretical framework to define it and propose a proof of concept based on Augmented Objects and a color codification mechanism. Finally, we evaluate and analyze the strengths and limitations of such approach with people with cognitive disabilities. PMID:23012573

A Focusing Method in the Calibration Process of Image Sensors Based on IOFBs

2010-01-01

A focusing procedure in the calibration process of image sensors based on Incoherent Optical Fiber Bundles (IOFBs) is described using the information extracted from fibers. These procedures differ from any other currently known focusing method due to the non spatial in-out correspondence between fibers, which produces a natural codification of the image to transmit. Focus measuring is essential prior to carrying out calibration in order to guarantee accurate processing and decoding. Four algorithms have been developed to estimate the focus measure; two methods based on mean grey level, and the other two based on variance. In this paper, a few simple focus measures are defined and compared. Some experimental results referred to the focus measure and the accuracy of the developed methods are discussed in order to demonstrate its effectiveness. PMID:22315526

Following a difficult period of service provision, an agency determined that drastic changes were needed to improve agency-wide capacity and functioning. The agency engaged in an organizational level self-assessment aimed at identifying areas for improvement and beginning work towards determining professional standards for service. Results of this organizational self-assessment paved the way for pursuing accreditation of its services, and the agency became the first public agency in its state to be accredited by the Council on Accreditation in all eligible services. This case study describes this agency's efforts in engaging in an organizational self-assessment, the analysis and codification of their practices, and their eventual development of a systematized process for capturing, evaluating and improving practice.

To unify and organize reporting, an International Urogynecological Association (IUGA)/International Continence Society (ICS) expert consortium published terminology guidelines with a classification system for complications related to implants used in female pelvic surgery. We hypothesize that the complexity of the codification system may be a hindrance to precision, especially with decreasing levels of postgraduate expertise. Residents, fellows, and attending physicians were asked to code seven test cases taken from published literature. Category, timing, and site components of the classification system were assessed independently and according to the level of training. Interobserver reliability was calculated as percent agreement and Fleiss' kappa statistic. A total of 24 participants (6 attending physicians, 3 fellows, and 15 residents) were tested. The percent agreement showed significant variation when classified by level of training. In all categories, attending physicians had the greatest percentage agreement and largest kappa. The most agreement was seen when attending physicians classified mesh complications by time, 71% agreement with kappa 0.73 [95% confidence interval (CI) 0.58-0.88]. For the same task, the percentage agreement for fellows was 57%, kappa 0.55 (95% CI 0.23-0.87) and with residents 57%, kappa 0.71([95% CI 0.64-0.78). Interestingly, the site component of the classification system had the least overall agreement and lowest kappa [0%, kappa 0.29 (95% CI 0.26-0.32)] followed by the category component [14%, kappa 0.48 (95% CI 0.46-0.5)]. The IUGA/ICS mesh complication classification system has poor interobserver reliability. This trended downward with decreasing postgraduate level; however, we did not have sufficient statistical power to show an association when stratifying by all training levels. This highlights the complex nature of the classification system in its current form and its limitation for widespread clinical and research application.

Global governance, international health law and WHO: looking towards the future.

Taylor, Allyn L.

2002-01-01

The evolving domain of international health law encompasses increasingly diverse and complex concerns. Commentators agree that health development in the twenty-first century is likely to expand the use of conventional international law to create a framework for coordination and cooperation among states in an increasingly interdependent world. This article examines the forces and factors behind the emerging expansion of conventional international health law as an important tool for present and future multilateral cooperation. It considers challenges to effective international health cooperation posed for intergovernmental organizations and other actors involved in lawmaking. Although full consolidation of all aspects of future international health lawmaking under the auspices of a single international organization is unworkable and undesirable, the World Health Organization (WHO) should endeavour to serve as a coordinator, catalyst and, where appropriate, platform for future health law codification. Such leadership by WHO could enhance coordination, coherence and implementation of international health law policy. PMID:12571727

Fast Modeling of Binding Affinities by Means of Superposing Significant Interaction Rules (SSIR) Method

PubMed Central

Besalú, Emili

2016-01-01

The Superposing Significant Interaction Rules (SSIR) method is described. It is a general combinatorial and symbolic procedure able to rank compounds belonging to combinatorial analogue series. The procedure generates structure-activity relationship (SAR) models and also serves as an inverse SAR tool. The method is fast and can deal with large databases. SSIR operates from statistical significances calculated from the available library of compounds and according to the previously attached molecular labels of interest or non-interest. The required symbolic codification allows dealing with almost any combinatorial data set, even in a confidential manner, if desired. The application example categorizes molecules as binding or non-binding, and consensus ranking SAR models are generated from training and two distinct cross-validation methods: leave-one-out and balanced leave-two-out (BL2O), the latter being suited for the treatment of binary properties.

This study is the result of an extended project, named: The systematization of nursing care in the perspective of complex thinking. The objective of this qualitative study is to better comprehend the meaning of the systematization of nursing care among healthcare professionals. The Data-Based Theory was used as a methodological reference. Data were collected by interviewing three sample groups, in a total of fifteen healthcare professionals. Data codification and analysis led us to the central theme: Viewing the Systematization of Nursing Care (SNC) as an Interactive and Complex Phenomenon. This theme is complemented by two phenomena. In this article, we discuss the phenomenon: Verifying the necessity of on interactive, complementary, and multi-professional process. The Systematization of Nursing Care is part of a process that has been developing over time by nurses committed to improve the care given to the patient, since they view the necessity for interactive, complementary, and multi-professional care.

Psychological underpinnings of intrafamilial computer-mediated communication: a preliminary exploration of CMC uptake with parents and siblings.

PubMed

Goby, Valerie Priscilla

2011-06-01

This preliminary study investigates the uptake of computer-mediated communication (CMC) with parents and siblings, an area on which no research appears to have been conducted. Given the lack of relevant literature, grounded theory methodology was used and online focus group discussions were conducted in an attempt to generate suitable hypotheses for further empirical studies. Codification of the discussion data revealed various categories of meaning, namely: a perceived inappropriateness of CMC with members of family of origin; issues relating to the family generational gap; the nature of the offline sibling/parent relationship; the non-viability of online affordances such as planned self-disclosure, deception, identity construction; and disinhibition in interactions with family-of-origin members. These themes could be molded into hypotheses to assess the psychosocial limitations of CMC and to determine if it can indeed become a ubiquitous alternative to traditional communication modes as some scholars have claimed.

Nutrition: ethical issues and challenges.

Rucker, Robert B; Rucker, Michael R

2016-11-01

For nutrition and its associated disciplines, ethical considerations related to research are often complicated by factors that range from the use of experimental research designs that are overly holistic to inextricable links between nutrition research and marketing. As a consequence, there is the need for constant vigilance to assess and deal with apparent conflicts of interest. Also, there are few scientific disciplines that are defined by cultural, religious, or political codifications as is nutrition. Accordingly, examples of historical, cultural, and political events are described that have influenced ethical approaches related to nutrition research. Furthermore, nutrition research questions are often multifaceted and require dealing with complex variables. In this regard, ethical principles and perspectives that have relevance to data acquisition, the publication and translation of nutrition research, and the marketing of nutritional products and concepts are highlighted.

Formal Representations of Eligibility Criteria: A Literature Review

Weng, Chunhua; Tu, Samson W.; Sim, Ida; Richesson, Rachel

2010-01-01

Standards-based, computable knowledge representations for eligibility criteria are increasingly needed to provide computer-based decision support for automated research participant screening, clinical evidence application, and clinical research knowledge management. We surveyed the literature and identified five aspects of eligibility criteria knowledge representations that contribute to the various research and clinical applications: the intended use of computable eligibility criteria, the classification of eligibility criteria, the expression language for representing eligibility rules, the encoding of eligibility concepts, and the modeling of patient data. We consider three of them (expression language, codification of eligibility concepts, and patient data modeling), to be essential constructs of a formal knowledge representation for eligibility criteria. The requirements for each of the three knowledge constructs vary for different use cases, which therefore should inform the development and choice of the constructs toward cost-effective knowledge representation efforts. We discuss the implications of our findings for standardization efforts toward sharable knowledge representation of eligibility criteria. PMID:20034594

Monitoring the Earthquake source process in North America

Herrmann, Robert B.; Benz, H.; Ammon, C.J.

2011-01-01

With the implementation of the USGS National Earthquake Information Center Prompt Assessment of Global Earthquakes for Response system (PAGER), rapid determination of earthquake moment magnitude is essential, especially for earthquakes that are felt within the contiguous United States. We report an implementation of moment tensor processing for application to broad, seismically active areas of North America. This effort focuses on the selection of regional crustal velocity models, codification of data quality tests, and the development of procedures for rapid computation of the seismic moment tensor. We systematically apply these techniques to earthquakes with reported magnitude greater than 3.5 in continental North America that are not associated with a tectonic plate boundary. Using the 0.02-0.10 Hz passband, we can usually determine, with few exceptions, moment tensor solutions for earthquakes with M w as small as 3.7. The threshold is significantly influenced by the density of stations, the location of the earthquake relative to the seismic stations and, of course, the signal-to-noise ratio. With the existing permanent broadband stations in North America operated for rapid earthquake response, the seismic moment tensor of most earthquakes that are M w 4 or larger can be routinely computed. As expected the nonuniform spatial pattern of these solutions reflects the seismicity pattern. However, the orientation of the direction of maximum compressive stress and the predominant style of faulting is spatially coherent across large regions of the continent.

Soil Security Assessment of Tasmania

2017-04-01

The concept of soil security aligns well with the aspirational and marketing policies of the Tasmanian Government, where increased agricultural expansion through new irrigation schemes and multiple-use State managed production forests co-exists beside pristine World Heritage conservation land, a major drawcard of the economically important tourism industry . Regarding the Sustainable Development Gaols (SDG's) this could be seen as a exemplar of the emerging tool for quantification of spatial soil security to effectively protect our soil resource in terms of food (SDG 2.4, 3.9) and water security (SDG 6.4, 6.6), biodiversity maintenance and safeguarding fragile ecosystems (SDG 15.3, 15.9). The recent development and application of Digital Soil Mapping and Assessment capacities in Tasmania to stimulate agricultural production and better target appropriate soil resources has formed the foundational systems that can enable the first efforts in quantifying and mapping Tasmanian Soil Security, in particular the five Soil Security dimensions (Capability, Condition, Capital, Codification and Connectivity). However, to provide a measure of overall soil security, it was necessary to separately assess the State's three major soil uses; Agriculture, Conservation and Forestry. These products will provide an indication of where different activities are sustainable or at risk, where more soil data is needed, and provide a tool to better plan for a State requiring optimal food and fibre production, without depleting its natural soil resources and impacting on the fragile ecosystems supporting environmental benefits and the tourism industry.

Malnutrition is known to independently affect patient outcomes. The aim of this study was to investigate the prevalence of patients at risk for malnutrition in an elective surgery patient cohort and to analyze the effects of malnutrition on morbidity, mortality, and hospital length of hospital (LOS). Furthermore, we aimed to evaluate the economic effect of a diligent coding of malnutrition, as a side diagnosis, in a simulation of the German Diagnosis-Related Group system. The nutritional status of 1244 patients undergoing elective surgery was standardized on the day of admission by the Nutritional Risk Screening (NRS) 2002. To quantify the influence of malnutrition on revenue, the real DRGs of all patients were grouped. In simulation, an appropriate International Classification of Diseases code was used as a secondary diagnosis for all malnourished patients based on the NRS rating. A multivariate logistic regression analysis and a Cox regression were performed to identify potential confounders and to determine the adjusted effect of nutritional status on the occurrence of complications and hospital LOS. The prevalence of patients at risk for malnutrition (NRS ≥3) was 24.1% (300 of 1244). These patients showed a significant increase in hospital LOS (13 versus 7 d). Additionally, postoperative complications were significantly higher in this group (7.23% versus 6.91%). Including malnutrition in the Diagnosis-Related Group coding system resulted in a reimbursement of €1979.67 per patient at risk for malnutrition and a total reimbursement of €79,186.73 for all patients at risk for malnutrition in the present study. Establishment of a structured, comprehensive assessment of the nutritional status of hospitalized patients can repetitiously identify patients at risk for malnutrition. Additionally, the diligent codification of malnutrition can lead to cost compensation in the German Diagnosis-Related Group system. Copyright © 2016 Elsevier Inc. All rights reserved.

Innovative power conversion system for the French SFR prototype, ASTRID

2012-07-01

In the framework of the French Act of 28 June 2006 about nuclear materials and waste management, the prototype ASTRID (Advanced Sodium Technological Reactor for Industrial Demonstration), foreseen in operation by the 20's, will have to demonstrate not only the minor actinide transmutation capability, but also the progress made in Sodium Fast Reactor (SFR) technology on an industrial scale, by qualifying innovative options. Some of these options still require improvements, especially in the field of operability and safety. In fact, one of the main issues with the standard steam/water Power Conversion System (PCS) of SFR is the fast and energeticmore » chemical reaction between water and sodium, which could occur in steam generators in case of tube failure. To manage the sodium/water reaction, one way consists in minimizing the impact of such event: hence studies are carried out on steam generator design, improvement of the physical knowledge of this phenomenon, development of numerical simulation to predict the reaction onset and consequences, and associated detection improvement. On the other hand, the other way consists in eliminating sodium/water reaction. In this frame, the CEA contribution to the feasibility evaluation of an alternative innovative PCS (replacing steam/water by 180 bar pressurised nitrogen) is focused on the following main topics: - The parametric study leading to nitrogen selection: the thermodynamic cycle efficiency optimisation on Brayton cycles is performed with several gases at different pressures. - The design of innovative compact heat exchangers for the gas loop: here the key points are the nuclear codification associated with inspection capability, the innovative welding process and the thermal-hydraulic and thermal-mechanic optimisations. After a general introduction of the ASTRID project, this paper presents in detail these different feasibility studies being led on the innovative gas PCS for an SFR. (authors)« less

Preventing biological weapon development through the governance of life science research.

PubMed

Epstein, Gerald L

2012-03-01

The dual-use dilemma in the life sciences-that illicit applications draw on the same science and technology base as legitimate applications-makes it inherently difficult to control one without inhibiting the other. Since before the September 11 attacks, the science and security communities in the United States have struggled to develop governance processes that can simultaneously minimize the risk of misuse of the life sciences, promote their beneficial applications, and protect the public trust. What has become clear over that time is that while procedural steps can be specified for assessing and managing dual-use risks in the review of research proposals, oversight of ongoing research, and communication of research results, the actions or decisions to be taken at each of these steps to mitigate dual-use risk defy codification. Yet the stakes are too high to do nothing, or to be seen as doing nothing. The U.S. government should therefore adopt an oversight framework largely along the lines recommended by the National Science Advisory Board for Biosecurity almost 5 years ago-one that builds on existing processes, can gain buy-in from the scientific community, and can be implemented at modest cost (both direct and opportunity), while providing assurance that a considered and independent examination of dual-use risks is being applied. Without extraordinary visibility into the actions of those who would misuse biology, it may be impossible to know how well such an oversight system will actually succeed at mitigating misuse. But maintaining the public trust will require a system to be established in which reasonably foreseeable dual-use consequences of life science research are anticipated, evaluated, and addressed.

Object and spatial visual working memory are impaired in schizophrenic patients. It is not clear if the impairments reside in each memory subsystem alone or also in the central executive component that coordinates these processes. In order to elucidate which memory component is impaired, we developed a paradigm with single spatial and object working memory tasks and dual ones with two different delays (5 and 30 s). Fifteen schizophrenic patients and 14 control subjects performed these tests. Schizophrenic patients had a poorer performance compared to normal controls in all tasks and in all time delays. Both schizophrenics and controls performed significantly worse in the object task than in the spatial task. The performance was even worse in the dual task compared to the singles ones in schizophrenic patients but not in controls. These data suggest that visuospatial performance deficits in schizophrenia are due to both visuospatial memory subsystems impairments and central executive ones. The pattern of deficits observed points to a codification or evocation deficit and not to a maintenance one.

Nurses and the sterilization experiments of Auschwitz: a postmodernist perspective.

PubMed

Benedict, Susan; Georges, Jane M

2006-12-01

The medical experiments conducted on non-consenting prisoners of Nazi concentration camps during World War II necessitated the codification of principles to protect human subjects of research. Auschwitz was the largest and one of the most infamous of the camps and the site of numerous 'medical' experiments. This historical study uses primary source documents obtained from archives in England and Germany to describe one type of experiment carried out at Auschwitz - the sterilization experiments. The purpose of these experiments was to perfect a technique in which non-Aryans could be prevented from reproducing while still being able to work as slave laborers. These narratives regarding the sterilization experiments at Auschwitz are remarkable in that they contain previously undocumented information regarding the voluntary and involuntary involvement of nurses. Following these narratives, a discussion of ethics in relation to the Holocaust is presented with a specific focus on the work of Agamben. Implications of the Auschwitz narratives for the application of codes of ethical principles and contemporary nursing are discussed from a postmodernist perspective.

Observing other people in action activates the "mirror neuron system" that serves for action comprehension and prediction. Recent evidence suggests that this function requires a high level codification triggered not only by components of motor behavior, but also by the environment where the action is embedded. An overlooked component of action perceiving is the one related to the emotional information provided by the context where the observed action takes place. Indeed, whether valence and arousal associated to an emotion might exert an influence on motor system activation during action observation has not been assessed so far. Here, cortico-spinal excitability of the left motor cortex was recorded in three groups of subjects. In the first condition, motor-evoked potential (MEPs) were recorded from a muscle involved in the grasping movement (i.e., abductor pollicis brevis, APB) while participants were watching the same reach-to-grasp movement embedded in contexts with negative emotional valence, but different levels of arousal: sadness (low arousal), and disgust (high arousal) ("Context plus Movement-APB" condition). In the second condition, MEPs were recorded from APB muscle while participants were observing static images representing the contexts in which the movement observed by participants in "Context plus Movement-APB" condition took place ("Context Only-APB" condition). Finally, in the third condition, MEPS were recorded from a muscle not involved in the grasping action, i.e., abductor digiti minimi, ADM, while participants were watching the same videos shown during the "Context plus Movement-APB" condition ("Context plus Movement-ADM" condition). Results showed a greater increase of cortical excitability only during the observation of the hand moving in the context eliciting disgust, and these changes were specific for the muscle involved in the observed action. Our findings show that the emotional context in which a movement occurs modulates motor resonance and that the combination of negative valence/high arousal drives the greater response in the observer's mirror neuron system in a strictly muscle specific fashion.

Forensic Medicine and the Military Population: International Dental Records and Personal Identification Concerns.

The first goal of this research was to perceive the global commitment towards the organization and archiving of dental records and to compare it with each country's security risk rating. The second one was to study dental records in a sample of the Portuguese military population, using the available national dental records. An e-mail was sent to representative dentistry associations in several countries, requesting some information concerning the professionals' awareness of this issue. After obtaining permission from the Ethics Committee, the information was collected through the Forensic Dental Symbols® system into the Dental Encoder®, as an extension of a Spanish study, and a generic codification was used (unrestored, restored, missing and crowned teeth). The most common dental record retention period is ten years after treatment. Observing the samples' dental records (595 files), we found a total of 19 040 analyzed teeth, with the following frequencies: unrestored (89.6%), restored (7.0%), missing (2.2%) and crowned (1.1%). There is a wide range of guidelines on how long dentists should keep dental records. Especially for the military population, dental records must include detailed information concerning each tooth situation, in order to support the process of human identification. This article reinforces the need for mandatory quality dental records in all countries, which must be efficiently stored and easily accessible in case dental identification is necessary. For the military population, these requirements are especially important, due to the added risks to which this group is subject.

Description and Codification of Miscanthus × giganteus Growth Stages for Phenological Assessment

2017-01-01

Triploid Miscanthus × giganteus (Greef et Deu. ex Hodkinson et Renvoize) is a sterile, perennial grass used for biomass production in temperate environments. While M. × giganteus has been intensively researched, a scale standardizing description of M. × giganteus morphological stages has not been developed. Here we provide such a scale by adapting the widely-used Biologische Bundesanstalt, Bundessortenamt, CHemische Industrie (BBCH) scale and its corresponding numerical code to describe stages of morphological development in M. × giganteus using observations of the “Freedom” and “Illinois” clone in Iowa, USA. Descriptive keys with images are also presented. Because M. × giganteus plants overlap in the field, the scale was first applied to individual stems and then scaled up to assess plants or communities. Of the 10 principal growth stages in the BBCH system, eight were observed in M. × giganteus. Each principal stage was subdivided into secondary stages to enable a detailed description of developmental progression. While M. × giganteus does not have seed development stages, descriptions of those stages are provided to extend the scale to other Miscanthus genotypes. We present methods to use morphological development data to assess phenology by calculating the onset, duration, and abundance of each developmental stage. This scale has potential to harmonize previously described study-specific scales and standardize results across studies. Use of the precise staging presented here should more tightly constrain estimates of developmental parameters in crop models and increase the efficacy of timing-sensitive crop management practices like pest control and harvest.

Intestinal parasites are the causative agents of common infections responsible for significant public health problems in developing countries and generally linked to lack of sanitation, safe water, and improper hygiene. More than two billion people throughout the world live with unrelenting illness due to intestinal parasitic infections (IPIs). The purposes of this study are to assess knowledge, attitudes, and practices on IPIs and investigate the relationship with prevalence of intestinal parasites among a low-income group of inhabitants from two communities of the Travessão District area, Campos dos Goytacazes, north of Rio de Janeiro State, Brazil. The two communities are known as "Parque Santuário," which is an urban slum with miserable living conditions, and "Arraial," where the socioeconomic and educational levels are better, neither having a sanitary infrastructure with an excreta collection system. Questionnaires revealed that both communities had local and specific codification to denominate the intestinal parasites and present correct knowledge on the theme but ignored some aspects of IPI transmission, with the Arraial population being better informed (p < 0.05). The overall prevalence of IPIs in Parque Santuário (49.7%) was greater than in Arraial (27.2%) (p < 0.001; prevalence ratio/95% confidence interval 1.83/1.50-2.23). This study reports the real IPI situation in the Travessão District and also reinforces the need to continue the investigation on the impact of combined prophylactic methods, educational measures, and socioeconomic and sanitary improvements by governmental authorities and the local popular organization.

The objective of the seminar was to present the current state of the art in Leak-Before-Break (LBB) methodology development, validation, and application in an international forum. With particular emphasis on industrial applications and regulatory policies, the seminar provided an opportunity to compare approaches, experiences, and codifications developed by different countries. The seminar was organized into four topic areas: status of LBB applications; technical issues in LBB methodology; complementary requirements (leak detection and inspection); LBB assessment and margins. As a result of this seminar, an improved understanding of LBB gained through sharing of different viewpoints from different countries, permits consideration of:more » simplified pipe support design and possible elimination of loss-of-coolant-accident (LOCA) mechanical consequences for specific cases; defense-in-depth type of applications without support modifications; support of safety cases for plants designed without the LOCA hypothesis. In support of these activities, better estimates of the limits to the LBB approach should follow, as well as an improvement in codifying methodologies.

Dipolar-dephasing 13C NMR studies of decomposed wood and coalified xylem tissue: Evidence for chemical structural changes associated with defunctionalization of lignin structural units during coalification

USGS Publications Warehouse

Hatcher, P.G.

1988-01-01

A series of decomposed and coalified gymnosperm woods was examined by conventional solid-state 13C nuclear magnetic resonance (NMR) and by dipolar-dephasing NMR techniques. The results of these NMR studies for a histologically related series of samples provide clues as to the nature of codification reactions that lead to the defunctionalization of lignin-derived aromatic structures. These reactions sequentially involve the following: (1) loss of methoxyl carbons from guaiacyl structural units with replacement by hydroxyls and increased condensation; (2) loss of hydroxyls or aryl ethers with replacement by hydrogen as rank increases from lignin to high-volatile bituminous coal; (3) loss of alkyl groups with continued replacement by hydrogen. The dipolar-dephasing data show that the early stages of coalification in samples examined (lignin to lignite) involve a decreasing degree of protonation on aromatic rings and suggest that condensation is significant during coalification at this early stage. An increasing degree of protonation on aromatic rings is observed as the rank of the sample increases from lignite to anthracite.

Heavy-ion dominance near Cluster perigees

Time periods in which heavy ions dominate over H+ in the energy range of 1-40 keV were observed by the Cluster Ion Spectrometry (CIS)/COmposition DIstribution Function (CODIF) instrument onboard Cluster Spacecraft 4 at L values less than 4. The characteristic feature is a narrow flux peak at around 10 keV that extends into low L values, with He+ and/or O+ dominating. In the present work we perform a statistical study of these events and examine their temporal occurrence and spatial distribution. The observed features, both the narrow energy range and the heavy-ion dominance, can be interpreted using a model of ion drift from the plasma sheet, subject to charge exchange losses. The narrow energy range corresponds to the only energy range that has direct drift access from the plasma sheet during quiet times. The drift time to these locations from the plasma sheet is > 30 h, so that charge exchange has a significant impact on the population. We show that a simple drift/loss model can explain the dependence on L shell and MLT of these heavy-ion-dominant time periods.

To quantify the Lower Extremity Amputations (LEA) incidence in population with and without diabetes mellitus (DM). Retrospective cohort study of all the LEA carried out during 2001-2006 in area 3 of Madrid, from the codification of the reports of discharge reports. 310 LEA were carried out. The age-ajusted LEA incidence for any reason was 19,2/10(5) inhabitants per year (27,2 y 11,2 for men and women respectively). 261 were not-traumatic and non-tumoural (NTT) LEA, 76% were associated with DM and the incidence was 191/10(5) people with DM per year (95% confidence interval [CI(95)] 122-299) and 4,4/10(5) for people without DM per year (CI(95) 7-23), with a risk ratio of 44 (CI(95) 23-73). The LEA rates in population with o without diabetes are higher than the previously communicated in Madrid. It would appear convenient to design strategies to reduce the LEA rates.

Ibn Sina, the most eminent Muslim physician, illuminative philosopher, great thinker and a versatile genius is regarded as the "Father of Early Modern Medicine" and as the "Father of Clinical Pharmacology". The "Kitab al-Qanun fi-al-Tibb", commonly known as the "Canon Medicinae" is the most important of his medical works and, at the same time, the most carefully preserved treasury both in original Arabic and in the initial Latin version. It is the final codification of all Greco-Arabic medical thoughts up to his time, enriched and modified with his own scientific experimentations and independent observations. It is considered "The First Textbook of Medicine on the Earth". The "Canon" surpassed the books of Hippocrates and Galen and remained supreme for more than six centuries, in the West. Ibn Sina described "Seven Doctrines" for Preservation of Health, based on the Mudawa Salookia, in his magnum opus. The roots of these principles can be traced, to a significant extent, to Egyptian Medicine, Hebrew Medicine, Greek Medicine, Roman Medicine, Traditional Chinese Medicine, Ancient Persian Medicine, Ayurvedic Medicine (Hindu Medicine) and Islamic Medicine.

It is in the nature of these kind of services, that visitors would share their question and remarks with the authors specialized in a particular topic. Among others these circumstances led to the format and content-related regulation of websites. In a nationwide research the authors examined, to what extent the Hungarian sites meet the requirements of the Health on Net codification and the criteria of the European Union Committee. By studying the quality criteria-related websites, the authors examined each Hungarian website to see how the Hungarian pages live up to the regulations. The work concentrates on the content, but it does not neglect functional analysis either. The authors conclude, that in spite of shortcomings, home webpages aim to keep the directives of the European Union.

Exploring the QSAR's predictive truthfulness of the novel N-tuple discrete derivative indices on benchmark datasets.

Graph derivative indices (GDIs) have recently been defined over N-atoms (N = 2, 3 and 4) simultaneously, which are based on the concept of derivatives in discrete mathematics (finite difference), metaphorical to the derivative concept in classical mathematical analysis. These molecular descriptors (MDs) codify topo-chemical and topo-structural information based on the concept of the derivative of a molecular graph with respect to a given event (S) over duplex, triplex and quadruplex relations of atoms (vertices). These GDIs have been successfully applied in the description of physicochemical properties like reactivity, solubility and chemical shift, among others, and in several comparative quantitative structure activity/property relationship (QSAR/QSPR) studies. Although satisfactory results have been obtained in previous modelling studies with the aforementioned indices, it is necessary to develop new, more rigorous analysis to assess the true predictive performance of the novel structure codification. So, in the present paper, an assessment and statistical validation of the performance of these novel approaches in QSAR studies are executed, as well as a comparison with those of other QSAR procedures reported in the literature. To achieve the main aim of this research, QSARs were developed on eight chemical datasets widely used as benchmarks in the evaluation/validation of several QSAR methods and/or many different MDs (fundamentally 3D MDs). Three to seven variable QSAR models were built for each chemical dataset, according to the original dissection into training/test sets. The models were developed by using multiple linear regression (MLR) coupled with a genetic algorithm as the feature wrapper selection technique in the MobyDigs software. Each family of GDIs (for duplex, triplex and quadruplex) behaves similarly in all modelling, although there were some exceptions. However, when all families were used in combination, the results achieved were quantitatively higher than those reported by other authors in similar experiments. Comparisons with respect to external correlation coefficients (q 2 ext ) revealed that the models based on GDIs possess superior predictive ability in seven of the eight datasets analysed, outperforming methodologies based on similar or more complex techniques and confirming the good predictive power of the obtained models. For the q 2 ext values, the non-parametric comparison revealed significantly different results to those reported so far, which demonstrated that the models based on DIVATI's indices presented the best global performance and yielded significantly better predictions than the 12 0-3D QSAR procedures used in the comparison. Therefore, GDIs are suitable for structure codification of the molecules and constitute a good alternative to build QSARs for the prediction of physicochemical, biological and environmental endpoints.

The Y-12 Plant conducts a surface water monitoring program in response to DOE Orders and state of Tennessee requirements under the National Pollutant Discharge Elimination System (NPDES). The anticipated codification of DOE Order 5400.5 for radiation protection of the public and the environment (10 CFR Part 834) will require an environmental radiation protection plan (ERPP). The NPDES permit issued by the state of Tennessee requires a radiological monitoring plan (RMP) for Y-12 Plant surface waters. In a May 4, 1995 memo, the state of Tennessee, Division of Water Pollution Control, stated their desired needs and goals regarding the content ofmore » RMPs, associated documentation, and data resulting from the RMPs required under the NPDES permitting system (L. Bunting, General Discussion, Radiological Monitoring Plans, Tennessee Division of Water Pollution Control, May 4,1995). Appendix A provides an overview of how the Y-12 Plant will begin to address these needs and goals. It provides a more complete, documented basis for the current Y-12 Plant surface water monitoring program and is intended to supplement documentation provided in the Annual Site Environmental Reports (ASERs), NPDES reports, Groundwater Quality Assessment Reports, and studies conducted under the Y-12 Plant Environmental Restoration (ER) Program. The purpose of this update to the Y-12 Plant RMP is to satisfy the requirements of the current NPDES permit, DOE Order 5400.5, and 10 CFR Part 834, as current proposed, by defining the radiological monitoring plan for surface water for the Y-12 Plant. This plan includes initial storm water monitoring and data analysis. Related activities such as sanitary sewer and sediment monitoring are also summarized. The plan discusses monitoring goals necessary to determine background concentrations of radionuclides, to quantify releases, determine trends, satisfy regulatory requirements, support consequence assessments, and meet requirements that releases be ``as low as reasonably achievable`` (ALARA).« less

There is no widely accepted definition of incident for primary care doctors in France and no taxonomic classification system for epidemiological use. In preparation for a future epidemiological study on primary care incidents in France (the ESPRIT study), this work was designed to identify the definitions and taxonomic classifications used internationally along with the usual methods and results in terms of frequency in the literature. The goal was to determine a French definition and taxonomy. Systematic review of the literature and consensus methods. An exhaustive search of epidemiological surveys was performed. A structured grid was used. After having identified the definitions used in the literature, a definition was chosen using the focus groups method. Taxonomies identified in the literature were classified by relationship, architecture, code number, and number of studies published. Subsequently, a consensus among experts, who independently tested these taxonomies on six incidents, was reached for choosing the most appropriate for epidemiological data collection (little information on a large number of cases). Twenty-four papers reporting 17 studies were selected among 139 articles. Five definitions and eight taxonomies were found. The chosen definition of incident was based on the WHO definition "A patient safety incident is an event or circumstance that could have resulted, or did result, in harm to a patient, and whose wish it is not repeated again". The test of incidents resulted in the choice of the TAPS version of the International Taxonomy of Medical Error in Primary Care for a reproducible and internationally recognized codification and the tempos method for its current use in French general practice. The definitions, taxonomies, data collection characteristics and frequency of incidents results in the international literature on incidents in primary care are key components for the preparation of an epidemiological survey on incidents in primary care.

The Modern Solar House: Architecture, Energy, and the Emergence of Environmentalism, 1938--1959

NASA Astrophysics Data System (ADS)

Barber, Daniel A.

This dissertation describes the active discourse regarding solar house heating in American architectural, engineering, political, economic, and corporate contexts from the eve of World War II until the late 1950s. Interweaving these multiple narratives, the aim of the project is threefold: to document this vital discourse, to place it in the context of the history of architecture, and to trace through it the emergence of a techno-cultural environmentalism. Experimentation in the solar house relied on the principles of modern architecture for both energy efficiency and claims to cultural relevance. A passive "solar house principle" was developed in the late 30s in the suburban houses of George Fred Keck that involved open plans and flexible roof lines, and emphasized volumetric design. Spurred by wartime concern over energy resource depletion, architectural interest in solar heating also engaged an engineering discourse; in particular, an experimental program at the Massachusetts Institute of Technology led to four solar houses and a codification of its technological parameters. Attention to the MIT projects at the UN and in the Truman and Eisenhower administrations placed the solar house as a central node in an emergent network exploring the problems and possibilities of a renewable resource economy. Further experimentation elaborated on connections between this architecturalengineering discourse and the technical assistance regimes of development assistance; here by MIT researcher Maria Telkes, who also collaborated, at different junctures, with the architects Eleanor Raymond and Aladar Olgyay. The solar house discourse was further developed as a cultural project in the 1958 competition to design a solar heated residence, "Living With the Sun," which coalesced the diverse formal tendencies of midcentury modernism to promote the solar house as an innovation in both lifestyle and policy. Though the examples described are not successful as either technological objects and cultural projects, the story of the modern solar house excavates a history of the present anxiety concerning the relationship between environmental and social conditions. Perhaps most cogently, the narrative reconfigures the role of architecture within such discussions, as a site for both technological innovation and for experimentation in the formation of an environmentalist culture.

In the turmoil of a rapidly changing economy the Albanian government needs accurate and timely information for management of their natural resources and formulation of land-use policies. The transformation of the forestry sector has required major changes in the legal, regulatory and management framework. The World Bank financed Albanian National Forest Inventory project provides an analysis of spatially explicit land-cover/use change dynamics in the period 1991-2001 using the FAO/UNEP Land Cover Classification System for codification of classes, satellite remote sensing and field survey for data collection and elements of the object-oriented geo-database approach to handle changes as an evolution of land-cover/use objects, i.e. polygons, over time to facilitate change dynamics analysis. Analysis results at national level show the trend of natural resources depletion in the form of modifications and conversions that lead to a gradual shift from land-cover/use types with a tree cover to less dense tree covers or even a complete removal of trees. Policy failure (e.g., corruption, lack of law enforcement) is seen as the underlying cause. Another major trend is urbanisation of areas near large urban centres that change urban-rural linkages. Furthermore, after privatisation agricultural areas increased in the hills where environmental effects may be detrimental, while prime agricultural land in the plains is lost to urbanisation. At district level, the local variability of spatially explicit land-cover/use changes shows different types of natural resources depletion. The distribution of changes indicates a regional prevalence, thus a decentralised approach to the natural resources management could be advocated.

PTSD in the U.S. military, and the politics of prevalence.

PubMed

Fisher, Michael P

2014-08-01

Despite the long-standing codification of posttraumatic stress disorder (PTSD) as a mental disorder, the diagnosis is a controversial one whose legitimacy is at times disputed, particularly in U.S. military contexts (e.g., McNally and Frueh 2013; McNally, 2003, 2007). These disputes often manifest in a struggle over prevalence rates. Utilizing data from in-depth interviews and relying on situational analysis methodology (Clarke, 2005), I highlight this struggle in the wake of a decade of U.S.-led war in Afghanistan and Iraq. I focus on the objects of contestation employed by public officials, veterans' advocates, and researchers to make or refute claims about PTSD prevalence. These objects of contestation include the diagnostic category and criteria; screening tools, procedures, or systems; and the individuals who express symptoms of the disorder. Based on these claims, I make two key interrelated assertions. First, PTSD is viewed by some public officials as an overly generalized or invalid diagnostic category that is often induced in or falsified by veterans or servicemembers. As such, PTSD is perceived by these stakeholders to be over-diagnosed. Compounding these perceptions are beliefs that PTSD is costly and negatively impacts military duty performance, and thus overall manpower. Second, there exist perceptions, largely on the part of veterans' advocates but also some public officials, that many servicemembers and veterans are not seeking treatment (and thus, a diagnosis) when they experience symptoms of PTSD. Thus, PTSD is perceived by these stakeholders to be under-diagnosed. Paradoxically, some public officials make both claims: that PTSD is over-diagnosed and under-diagnosed. I conclude by exploring the implications of these findings. Copyright © 2014 Elsevier Ltd. All rights reserved.

Laparoendoscopic single site totally extraperitoneal (TEP) hernia repair showed to be a feasible alternative to conventional laparoscopic hernia repair; nevertheless single site surgery, with the loss of instruments triangulation can be a demanding procedure. To overcome those hurdles, the Single Site® (SS) platform of the da Vinci (DV) Si robotic system enables to perform surgical procedures through a 25-mm skin incision, with a stable 3D vision and restoring an adequate triangulation of the surgical instruments. We present in details the technique and the preliminary results of DV-SS TEP, to our knowledge the first cases reported in literature. In March 2016, three consecutive male patients (mean age 46.6 years-mean BMI 25.3) with bilateral symptomatic inguinal hernia were submitted to DV-SS TEP in our institutions. Feasibility, codification of the technique, operative time and perioperative outcomes were recorded. All the procedures were completed as scheduled, with no conversion to other techniques. Mean operative time was 98.6 min, ranging between 155 and 55 min, reflecting the learning curve of the operating room team on this new procedure. No intraoperative or postoperative complications were experienced and all the patients were discharged within 24 h after surgery. Patients reported satisfactory postoperative course, with no recurrence of inguinal hernia and satisfaction in cosmetic result at 6-month follow-up. DV-SS TEP inguinal hernia repair showed to be feasible and effective surgical option for bilateral groin hernia repair. Patients' outcome was uneventful, with optimal cosmetic results. Further studies comparing this innovative technique to TEP or LESS TEP should be promoted.

Social energy: mining energy from the society

Zhang, Jun Jason; Gao, David Wenzhong; Zhang, Yingchen

The inherent nature of energy, i.e., physicality, sociality and informatization, implies the inevitable and intensive interaction between energy systems and social systems. From this perspective, we define 'social energy' as a complex sociotechnical system of energy systems, social systems and the derived artificial virtual systems which characterize the intense intersystem and intra-system interactions. The recent advancement in intelligent technology, including artificial intelligence and machine learning technologies, sensing and communication in Internet of Things technologies, and massive high performance computing and extreme-scale data analytics technologies, enables the possibility of substantial advancement in socio-technical system optimization, scheduling, control and management. In thismore » paper, we provide a discussion on the nature of energy, and then propose the concept and intention of social energy systems for electrical power. A general methodology of establishing and investigating social energy is proposed, which is based on the ACP approach, i.e., 'artificial systems' (A), 'computational experiments' (C) and 'parallel execution' (P), and parallel system methodology. A case study on the University of Denver (DU) campus grid is provided and studied to demonstrate the social energy concept. In the concluding remarks, we discuss the technical pathway, in both social and nature sciences, to social energy, and our vision on its future.« less

Social skills training, performed by human trainers, is a well-established method for obtaining appropriate skills in social interaction. Previous work automated the process of social skills training by developing a dialogue system that teaches social communication skills through interaction with a computer avatar. Even though previous work that simulated social skills training only considered acoustic and linguistic information, human social skills trainers take into account visual and other non-verbal features. In this paper, we create and evaluate a social skills training system that closes this gap by considering the audiovisual features of the smiling ratio and the head pose (yaw and pitch). In addition, the previous system was only tested with graduate students; in this paper, we applied our system to children or young adults with autism spectrum disorders. For our experimental evaluation, we recruited 18 members from the general population and 10 people with autism spectrum disorders and gave them our proposed multimodal system to use. An experienced human social skills trainer rated the social skills of the users. We evaluated the system's effectiveness by comparing pre- and post-training scores and identified significant improvement in their social skills using our proposed multimodal system. Computer-based social skills training is useful for people who experience social difficulties. Such a system can be used by teachers, therapists, and social skills trainers for rehabilitation and the supplemental use of human-based training anywhere and anytime.

Nuclear obligations: Nuremberg law, nuclear weapons, and protest

DOE Office of Scientific and Technical Information (OSTI.GOV)

Burroughs, J.R.

1991-01-01

Nuclear weapons use and deployment and nonviolent anti-nuclear protests are evaluated. Use of nuclear weapons would constitute war crimes and crimes against humanity as defined in both the Nuremberg Charter and Allied Control Council Law No. 10 and applied by the International Military Tribunal and other Nuremberg courts. Strategic and atomic bombing during World War 2 did not set a precedent for use of nuclear weapons. The consequentialist argument for World War 2 bombing fails and the bombing has also been repudiated by codification of the law of war in Protocol 1 to the 1949 Geneva Conventions. The legality ofmore » deploying nuclear weapons as instruments of geopolitical policy is questionable when measured against the Nuremberg proscription of planning and preparation of aggressive war, war crimes, and crimes against humanity and the United Nations Charter's proscription of aggressive threat of force. While states' practice of deploying the weapons and the arms-control treaties that regulate but do not prohibit mere possession provide some support for legality, those treaties recognize the imperative of preventing nuclear war, and the Nuclear Non-Proliferation Treaty commits nuclear-armed states to good-faith negotiation of nuclear disarmament.« less

Body and Corporality in adolescents and young adults with spinal cord injury.

2016-04-01

To describe the meaning given by adolescents and young adults to the changes in their bodies and corporality after a spinal cord injury. Qualitative study based on symbolic interactionism in which 12 adolescents and young adults, who had suffered spinal cord injury 6 months or more before, participated. The information was recollected through a series of in-depth interviews and field journals. The guidelines proposed by Corbin and Strauss were followed for the process of codification and categorization of the data. Four categories were identified that describe the meanings given by participants to the changes in their bodies and corporality: Transformation of self-image, living with contradictions in the relationships with others, withstanding the burden of a disability and adapting to the new conditions. The results allow for the comprehension of the meanings that are given by the people who have suffered a spinal cord lesion to their situation. This will in turn open the possibility of offering these people a better individual nursing care that focuses more on the particular needs, so that both they and their families can be helped on their way to adaptation to the new situation.

Studying frequency processing of the brain to enhance long-term memory and develop a human brain protocol.

PubMed

Friedrich, Wernher; Du, Shengzhi; Balt, Karlien

2015-01-01

The temporal lobe in conjunction with the hippocampus is responsible for memory processing. The gamma wave is involved with this process. To develop a human brain protocol, a better understanding of the relationship between gamma and long-term memory is vital. A more comprehensive understanding of the human brain and specific analogue waves it uses will support the development of a human brain protocol. Fifty-eight participants aged between 6 and 60 years participated in long-term memory experiments. It is envisaged that the brain could be stimulated through binaural beats (sound frequency) at 40 Hz (gamma) to enhance long-term memory capacity. EEG recordings have been transformed to sound and then to an information standard, namely ASCII. Statistical analysis showed a proportional relationship between long-term memory and gamma activity. Results from EEG recordings indicate a pattern. The pattern was obtained through the de-codification of an EEG recording to sound and then to ASCII. Stimulation of gamma should enhance long term memory capacity. More research is required to unlock the human brains' protocol key. This key will enable the processing of information directly to and from human memory via gamma, the hippocampus and the temporal lobe.

The Evolving Law of Disputed Relocation: constructing inner-city renewal practices in Shanghai, 1990-2005.

PubMed

Shih, Mi

2010-01-01

The forceful pursuit of inner-city renewal in Shanghai since the early 1990s has to a great extent achieved spatial modernization, but at the same time it has given rise to increasing conflicts over residential relocation. Using law as a prism through which to examine the dialectic relationship between renewal practices and disputed relocation, this article argues that the series of unprecedented enactments in law that have taken place during this period have both paved the way for real estate market expansion and been a significant source of relocation disputes in Shanghai. Rather than viewing law as simply given and determinate, the article traces the regulatory regime's codification of property practices as a means of actively responding to the requirements of the real estate market. Under large-scale renewal practices, residents' legal rights of "return settlement" (huiban) in inner-city areas were largely denied in the early 1990s, before being effectively abolished by the adoption of monetary compensation for displacement in the 2000s. The evolving law on property practices has greatly shaped the process of disputed relocation while simultaneously posing a potential challenge to China's use of law for market-oriented development.

Incentives and intrinsic motivation in healthcare.

PubMed

Berdud, Mikel; Cabasés, Juan M; Nieto, Jorge

It has been established in the literature that workers within public organisations are intrinsically motivated. This paper is an empirical study of the healthcare sector using methods of qualitative analysis research, which aims to answer the following hypotheses: 1) doctors are intrinsically motivated; 2) economic incentives and control policies may undermine doctors' intrinsic motivation; and 3) well-designed incentives may encourage doctors' intrinsic motivation. We conducted semi-structured interviews à-la-Bewley with 16 doctors from Navarre's Healthcare Service (Servicio Navarro de Salud-Osasunbidea), Spain. The questions were based on current theories of intrinsic motivation and incentives to test the hypotheses. Interviewees were allowed to respond openly without time constraints. Relevant information was selected, quantified and analysed by using the qualitative concepts of saturation and codification. The results seem to confirm the hypotheses. Evidence supporting hypotheses 1 and 2 was gathered from all interviewees, as well as indications of the validity of hypothesis 3 based on interviewees' proposals of incentives. The conclusions could act as a guide to support the optimal design of incentive policies and schemes within health organisations when healthcare professionals are intrinsically motivated.

Herpes zoster surveillance using electronic databases in the Valencian Community (Spain)

PubMed Central

2013-01-01

Background Epidemiologic data of Herpes Zoster (HZ) disease in Spain are scarce. The objective of this study was to assess the epidemiology of HZ in the Valencian Community (Spain), using outpatient and hospital electronic health databases. Methods Data from 2007 to 2010 was collected from computerized health databases of a population of around 5 million inhabitants. Diagnoses were recorded by physicians using the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM). A sample of medical records under different criteria was reviewed by a general practitioner, to assess the reliability of codification. Results The average annual incidence of HZ was 4.60 per 1000 persons-year (PY) for all ages (95% CI: 4.57-4.63), is more frequent in women [5.32/1000PY (95% CI: 5.28-5.37)] and is strongly age-related, with a peak incidence at 70-79 years. A total of 7.16/1000 cases of HZ required hospitalization. Conclusions Electronic health database used in the Valencian Community is a reliable electronic surveillance tool for HZ disease and will be useful to define trends in disease burden before and after HZ vaccine introduction.

Confocal laser endomicroscopy permits in-vivo microscopy evaluation during endoscopy procedures. It can be used in all the parts of the gastrointestinal tract and includes: Esophagus, stomach, small bowel, colon, biliary tract through and endoscopic retrograde cholangiopancreatography and pancreas through needles during endoscopic ultrasound procedures. Many researches demonstrated a high correlation of results between confocal laser endomicroscopy and histopathology in the diagnosis of gastrointestinal lesions; with accuracy in about 86% to 96%. Moreover, in spite that histopathology remains the gold-standard technique for final diagnosis of any diseases; a considerable number of misdiagnosis rate could be present due to many factors such as interpretation mistakes, biopsy site inaccuracy, or number of biopsies. Theoretically; with the diagnostic accuracy rates of confocal laser endomicroscopy could help in a daily practice to improve diagnosis and treatment management of the patients. However, it is still not routinely used in the clinical practice due to many factors such as cost of the procedure, lack of codification and reimbursement in some countries, absence of standard of care indications, availability, physician image-interpretation training, medico-legal problems, and the role of the pathologist. These limitations are relative, and solutions could be found based on new researches focused to solve these barriers.

Incorporating Social System Dynamics into the Food-Energy-Water System Resilience-Sustainability Modeling Process

In the face of climate change and multi-scalar governance objectives, achieving resilience of food-energy-water (FEW) systems requires interdisciplinary approaches. Through coordinated modeling and management efforts, we study "Innovations in the Food-Energy-Water Nexus (INFEWS)" through a case-study in the Columbia River Basin. Previous research on FEW system management and resilience includes some attention to social dynamics (e.g., economic, governance); however, more research is needed to better address social science perspectives. Decisions ultimately taken in this river basin would occur among stakeholders encompassing various institutional power structures including multiple U.S. states, tribal lands, and sovereign nations. The social science lens draws attention to the incompatibility between the engineering definition of resilience (i.e., return to equilibrium or a singular stable state) and the ecological and social system realities, more explicit in the ecological interpretation of resilience (i.e., the ability of a system to move into a different, possibly more resilient state). Social science perspectives include but are not limited to differing views on resilience as normative, system persistence versus transformation, and system boundary issues. To expand understanding of resilience and objectives for complex and dynamic systems, concepts related to inequality, heterogeneity, power, agency, trust, values, culture, history, conflict, and system feedbacks must be more tightly integrated into FEW research. We identify gaps in knowledge and data, and the value and complexity of incorporating social components and processes into systems models. We posit that socio-biophysical system resilience modeling would address important complex, dynamic social relationships, including non-linear dynamics of social interactions, to offer an improved understanding of sustainable management in FEW systems. Conceptual modeling that is presented in our study, represents a starting point for a continued research agenda that incorporates social dynamics into FEW system resilience and management.

2017-04-01

This paper investigates the feasibility of maintaining a social information system to support attendees at an academic conference. The main challenge of this work was to create an infrastructure where users' social activities, such as bookmarking, tagging, and social linking could be used to enhance user navigation and maximize the users' ability to locate two important types of information in conference settings: presentations to attend and attendees to meet. We developed Conference Navigator 3, a social conference support system that integrates a conference schedule planner with a social linking service. We examined its potential and functions in the context of a medium-scale academic conference. In this paper, we present the design of the system's socially enabled features and report the results of a conference-based study. Our study demonstrates the feasibility of social information systems for supporting academic conferences. Despite the low number of potential users and the short timeframe in which conferences took place, the usage of the system was high enough to provide sufficient data for social mechanisms. The study shows that most critical social features were highly appreciated and used, and provides direction for further research.

Humans live in societies full of rich and complex relationships that influence health. The ability to improve human health requires a detailed understanding of the complex interplay of biological systems that contribute to disease processes, including the mechanisms underlying the influence of social contexts on these biological systems. A longitudinal computational systems science approach provides methods uniquely suited to elucidate the mechanisms by which social systems influence health and well-being by investigating how they modulate the interplay among biological systems across the lifespan. In the present report, we argue that nonhuman primate social systems are sufficiently complex to serve as model systems allowing for the development and refinement of both analytical and theoretical frameworks linking social life to health. Ultimately, developing systems science frameworks in nonhuman primate models will speed discovery of the mechanisms that subserve the relationship between social life and human health. PMID:27148103

Chronicles of recent disasters. Are Agencies and Civil Protections getting sloppy?

NASA Astrophysics Data System (ADS)

Miozzo, D.; Altamura, M.; Ferraris, L.; Musso, L.

2010-09-01

Numerical Weather Prediction (NWP) models and forecasts have a paramount role in the real time decision making command chain. It is thanks to them that Civil Protection (CP) across Europe and the World were able to redeploy towards preventing calamities rather than passively awaiting for their happening. However, from the implementation of these new methodological and procedural instruments stems the process of codification of a generalized Ius Commune. This natural drive towards Positive Law grants the fruition and tutelage of new rights but, if not adequately controlled, can initiate vicious circles leading towards the overcriminalization of the system. Trials, intended against CP operators and guardians or guarantors, according to civil law acception, showed how meteorological weather prediction can be faulty and dangerously underestimate an incoming event. The margin of error unfolds on both a temporal and a spatial plan. The discrepancy which emerged from ex post analysis (Molini et al. 2009) tells us that state of the art instruments can possibly induce CP operators to make wrong decisions. In addition to these computational and modelling problems, the complex orography of our territories impedes to deterministically asses and characterize hydrometeorological risk. The best instrument in our hands, a part from radar and satellite data (which both have a yet important delay in the acquisition of data due to its transfer), is still represented by NWP models and by the experience of whom, on a daily basis, issues meteorological bulletins and alert whom are the foremost link between CPs and the population. Envisaging the problem of the overcriminalization phenomenon and its social consequences, unpredicted flash floods are extremely rare to count. Nevertheless they do happen and create the basis for a much more dangerous problem: the lowering of the alert threshold to an excessively precautionary level, thus, eliminating any kind of discretionality in assessing incoming risks. In order to reduce the possibility of being convicted, CP guardians are augmenting the number of alerts issued. Generalized, and more frequent, alerts are being issued, by so doing risk perception of the population is unawarely declining. The recent events in the French region of the Var are explicative of such a reality. The similarity that ties two systems of CP (Italy and France) to similar difficulties, in the first place demonstrate how the problem is transnational and not tied to national deficiencies, whilst, in the second place, makes necessary a critical analysis of the real risks that CP organizations are facing in terms of functionality and ability to communicate the real level of risk to the endangered citizenship. It is in these terms that we must think or, rather, rethink agencies and CP organizations. Implementing the best strategies, with the most advanced technologies, will not compensate the eventual disjunction between the core structure and the administrative periphery. Establishing operative mechanisms for the "last mile" and educating both the citizenship and the jurisprudential orders of our society to the undergoing risk of a collapse of CP institutions represents the main effort of our research and of this work.

The busy social brain: evidence for automaticity and control in the neural systems supporting social cognition and action understanding.

PubMed

Spunt, Robert P; Lieberman, Matthew D

2013-01-01

Much social-cognitive processing is believed to occur automatically; however, the relative automaticity of the brain systems underlying social cognition remains largely undetermined. We used functional MRI to test for automaticity in the functioning of two brain systems that research has indicated are important for understanding other people's behavior: the mirror neuron system and the mentalizing system. Participants remembered either easy phone numbers (low cognitive load) or difficult phone numbers (high cognitive load) while observing actions after adopting one of four comprehension goals. For all four goals, mirror neuron system activation showed relatively little evidence of modulation by load; in contrast, the association of mentalizing system activation with the goal of inferring the actor's mental state was extinguished by increased cognitive load. These results support a dual-process model of the brain systems underlying action understanding and social cognition; the mirror neuron system supports automatic behavior identification, and the mentalizing system supports controlled social causal attribution.

Oxytocin and vasopressin neural networks: implications for social behavioral diversity and translational neuroscience

PubMed Central

Johnson, Zachary V.; Young, Larry J.

2017-01-01

Oxytocin- and vasopressin-related systems are present in invertebrate and vertebrate bilaterian animals, including humans, and exhibit conserved neuroanatomical and functional properties. In vertebrates, these systems innervate conserved neural networks that regulate social learning and behavior, including conspecific recognition, social attachment, and parental behavior. Individual and species-level variation in central organization of oxytocin and vasopressin systems has been linked to individual and species variation in social learning and behavior. In humans, genetic polymorphisms in the genes encoding oxytocin and vasopressin peptides and/or their respective target receptors have been associated with individual variation in social recognition, social attachment phenotypes, parental behavior, and psychiatric phenotypes such as autism. Here we describe both conserved and variable features of central oxytocin and vasopressin systems in the context of social behavioral diversity, with a particular focus on neural networks that modulate social learning, behavior, and salience of sociosensory stimuli during species-typical social contexts.

2017-12-01

To critically analyze social work's role in Medicaid reform. We conducted semistructured interviews with 46 stakeholders from 10 US states that use a range of Medicaid reform approaches. We identified participants using snowball and purposive sampling. We gathered data in 2016 and analyzed them using qualitative methods. Multiple themes emerged: (1) social work participates in Medicaid reform through clinical practice, including care coordination and case management; (2) there is a gap between social work's practice-level and systems-level involvement in Medicaid innovations; (3) factors hindering social work's involvement in systems-level practice include lack of visibility, insufficient clarity on social work's role and impact, and too few resources within professional organizations; and (4) social workers need more training in health transformation payment models and policy. Social workers have unique skills that are valuable to building health systems that promote population health and reduce health inequities. Although there is considerable opportunity for social work to increase its role in Medicaid reform, there is little social work involvement at the systems level.

A Comparison of Social Dominance Theory and System Justification: The Role of Social Status in 19 Nations.

PubMed

Vargas-Salfate, Salvador; Paez, Dario; Liu, James H; Pratto, Felicia; Gil de Zúñiga, Homero

2018-07-01

This study tests specific competing hypotheses from social dominance theory/realistic conflict theory (RCT) versus system justification theory about the role of social status. In particular, it examines whether system justification belief and effects are stronger among people with low socioeconomic status, and in less socially developed and unequal nations than among better-off people and countries. A cross-national survey was carried out in 19 nations from the Americas, Western and Eastern Europe, Asia, and Oceania using representative online samples ( N = 14,936, 50.15% women, M age = 41.61 years). At the individual level, system justification beliefs, right-wing authoritarianism, social dominance orientation, national identification, sociopolitical conservatism, sex, age, and social status were measured. At the national level, the human development index and the Gini index were used. Multilevel analyses performed indicated that results fit better with the social dominance/RCT approach, as system justification was higher in high-status and developed nations; further, associations between legitimizing ideologies and system justification were stronger among high-status people.

The ‘social complexity hypothesis’ for communication posits that groups with complex social systems require more complex communicative systems to regulate interactions and relations among group members. Complex social systems, compared with simple social systems, are those in which individuals frequently interact in many different contexts with many different individuals, and often repeatedly interact with many of the same individuals in networks over time. Complex communicative systems, compared with simple communicative systems, are those that contain a large number of structurally and functionally distinct elements or possess a high amount of bits of information. Here, we describe some of the historical arguments that led to the social complexity hypothesis, and review evidence in support of the hypothesis. We discuss social complexity as a driver of communication and possible causal factor in human language origins. Finally, we discuss some of the key current limitations to the social complexity hypothesis—the lack of tests against alternative hypotheses for communicative complexity and evidence corroborating the hypothesis from modalities other than the vocal signalling channel.

Communities of Practice and Social Learning Systems: the Career of a Concept

NASA Astrophysics Data System (ADS)

Wenger, Etienne

The concept of community of practice was not born in the systems theory tradition. It has its roots in attempts to develop accounts of the social nature of human learning inspired by anthropology and social theory (Lave, 1988; Bourdieu, 1977; Giddens, 1984; Foucault, 1980; Vygotsky, 1978). But the concept of community of practice is well aligned with the perspective of systems traditions. A community of practice itself can be viewed as a simple social system. And a complex social system can be viewed as constituted by interrelated communities of practice. In this essay I first explore the systemic nature of the concept at these two levels. Then I use this foundation to look at the applications of the concept, some of its main critiques, and its potential for developing a social discipline of learning.

Disease implications of animal social network structure: A synthesis across social systems.

The disease costs of sociality have largely been understood through the link between group size and transmission. However, infectious disease spread is driven primarily by the social organization of interactions in a group and not its size. We used statistical models to review the social network organization of 47 species, including mammals, birds, reptiles, fish and insects by categorizing each species into one of three social systems, relatively solitary, gregarious and socially hierarchical. Additionally, using computational experiments of infection spread, we determined the disease costs of each social system. We find that relatively solitary species have large variation in number of social partners, that socially hierarchical species are the least clustered in their interactions, and that social networks of gregarious species tend to be the most fragmented. However, these structural differences are primarily driven by weak connections, which suggest that different social systems have evolved unique strategies to organize weak ties. Our synthetic disease experiments reveal that social network organization can mitigate the disease costs of group living for socially hierarchical species when the pathogen is highly transmissible. In contrast, highly transmissible pathogens cause frequent and prolonged epidemic outbreaks in gregarious species. We evaluate the implications of network organization across social systems despite methodological challenges, and our findings offer new perspective on the debate about the disease costs of group living. Additionally, our study demonstrates the potential of meta-analytic methods in social network analysis to test ecological and evolutionary hypotheses on cooperation, group living, communication and resilience to extrinsic pressures. © 2017 The Authors.

The CRF system and social behavior: a review

PubMed Central

Hostetler, Caroline M.; Ryabinin, Andrey E.

2013-01-01

The corticotropin-releasing factor (CRF) system plays a key role in a diversity of behaviors accompanying stress, anxiety and depression. There is also substantial research on relationships between social behaviors and the CRF system in a variety of taxa including fish, birds, rodents, and primates. Some of these relationships are due to the broad role of CRF and urocortins in stress and anxiety, but these peptides also modulate social behavior specifically. For example, the social interaction (SI) test is often used to measure anxiety-like behavior. Many components of the CRF system including CRF, urocortin1, and the R1 receptor have been implicated in SI, via general effects on anxiety as well as specific effects depending on the brain region. The CRF system is also highly responsive to chronic social stressors such as social defeat and isolation. Animals exposed to these stressors display a number of anxiety- and stress-related behaviors, accompanied by changes in specific components the CRF system. Although the primary focus of CRF research on social behavior has been on the deleterious effects of social stress, there are also insights on a role for CRF and urocortins in prosocial and affiliative behaviors. The CRF system has been implicated in parental care, maternal defense, sexual behavior, and pair bonding. Species differences in the ligands and CRF receptors have been observed in vole and bird species differing in social behavior. Exogenous administration of CRF facilitates partner preference formation in monogamous male prairie voles, and these effects are dependent on both the CRF R1 and R2 receptors. These findings are particularly interesting as studies have also implicated the CRF and urocortins in social memory. With the rapid progress of social neuroscience and in understanding the complex structure of the CRF system, the next challenge is in parsing the exact contribution of individual components of this system to specific social behaviors.

Kenney, J J

1990-02-01

An overview of the health care industry's trend toward multihealth systems is presented and specific adaptive strategies for social work managers in health care are suggested. The challenges to social work leaders during this transition from largely free-standing, privately owned health care institutions to corporately owned, horizontally and vertically integrated delivery systems are discussed in terms of identity, style, and substance. Directors of social work departments in multihealth corporations will need to resolve issues of institutional versus corporate identity as well as those of corporate versus professional identity. A multioptional management style that incorporates networking and political expertise should be cultivated. Substantive demands in the areas of management information systems, productivity, quality assurance, and budgeting also must be addressed. The emergence of multihealth systems poses major challenges and unique opportunities to the social work profession. Awareness of managerial strategies and critical content areas can help social work leaders enhance the role and contribution of social work in these exciting and complex health care delivery systems.

National health systems represent an organized social response that enables countries to improve, maintain and enhance the health status of their citizens. These evolve and are transformed according to changes in the biological, economic, political and social components of health. In Mexico there is currently a segmented health system, consisting of a bismarckian model of social security and a social protection in health model. The latter developed to comply with the fourth constitutional article by which health is no longer described as a right linked to the employment status of the individual. Given this reality at least three alternatives seem to emerge for the future: the permanence of a mixed health system with social security and social protection institutions with a similar weight within the national health system, or its opposite, the extension of social protection as a mechanism for widespread access. Given the challenges we face, it is desirable to establish a unified health system, the aim should be that health care is universally protected, as currently happens, but is guaranteed through a much more efficient and based in primary care health care system.

Altered reward system reactivity for personalized circumscribed interests in autism.

PubMed

Kohls, Gregor; Antezana, Ligia; Mosner, Maya G; Schultz, Robert T; Yerys, Benjamin E

2018-01-01

Neurobiological research in autism spectrum disorders (ASD) has paid little attention on brain mechanisms that cause and maintain restricted and repetitive behaviors and interests (RRBIs). Evidence indicates an imbalance in the brain's reward system responsiveness to social and non-social stimuli may contribute to both social deficits and RRBIs. Thus, this study's central aim was to compare brain responsiveness to individual RRBI (i.e., circumscribed interests), with social rewards (i.e., social approval), in youth with ASD relative to typically developing controls (TDCs). We conducted a 3T functional magnetic resonance imaging (fMRI) study to investigate the blood-oxygenation-level-dependent effect of personalized circumscribed interest rewards versus social rewards in 39 youth with ASD relative to 22 TDC. To probe the reward system, we employed short video clips as reinforcement in an instrumental incentive delay task. This optimization increased the task's ecological validity compared to still pictures that are often used in this line of research. Compared to TDCs, youth with ASD had stronger reward system responses for CIs mostly within the non-social realm (e.g., video games) than social rewards (e.g., approval). Additionally, this imbalance within the caudate nucleus' responsiveness was related to greater social impairment. The current data support the idea of reward system dysfunction that may contribute to enhanced motivation for RRBIs in ASD, accompanied by diminished motivation for social engagement. If a dysregulated reward system indeed supports the emergence and maintenance of social and non-social symptoms of ASD, then strategically targeting the reward system in future treatment endeavors may allow for more efficacious treatment practices that help improve outcomes for individuals with ASD and their families.

Vietnam: expanding the social security system.

Pruzin, D

1996-01-01

Viet Nam's shift toward a market-oriented economy has been associated with annual gross domestic product growth of more than 8% over the past 5 years. At the same time, the emergence of private-sector enterprises and subsequent closure of many state-run enterprises have had profound implications for Viet Nam's social protection systems. At present, only 5.6 million of the country's 33 million workers are covered under the state-run social insurance system. In 1995, the government moved to include private enterprises with 10 or more employees in its state benefits system. The International Labor Organization (ILO) has been working with the Vietnamese Government to design and implement a social security system that would extend coverage progressively to excluded sectors and provide support to workers who have become unemployed as a result of the economic transition process. At its Eighth National Congress, the Vietnamese Communist Party approved a 5-year social and economic plan calling for such an expansion of the social insurance system as well as for a guaranteed standard of living for pensioners. To facilitate anticipated changes, activities that were previously divided between the Ministry of Labor, Invalids, and Social Affairs and the Vietnam General Confederation of Labor have been assigned to the newly formed Vietnam Social Insurance (VSI) Organization. Under consideration is a plan to combine some VSI activities with those of the Vietnam Health Insurance Organization. The ILO will assist with training, computerization, and social security fund investing. Noncompliance is a major obstacle to planned expansion of the social security system; about 90% of private firms are still not paying into the system.

Crowd Sensing-Enabling Security Service Recommendation for Social Fog Computing Systems

Fog computing, shifting intelligence and resources from the remote cloud to edge networks, has the potential of providing low-latency for the communication from sensing data sources to users. For the objects from the Internet of Things (IoT) to the cloud, it is a new trend that the objects establish social-like relationships with each other, which efficiently brings the benefits of developed sociality to a complex environment. As fog service become more sophisticated, it will become more convenient for fog users to share their own services, resources, and data via social networks. Meanwhile, the efficient social organization can enable more flexible, secure, and collaborative networking. Aforementioned advantages make the social network a potential architecture for fog computing systems. In this paper, we design an architecture for social fog computing, in which the services of fog are provisioned based on “friend” relationships. To the best of our knowledge, this is the first attempt at an organized fog computing system-based social model. Meanwhile, social networking enhances the complexity and security risks of fog computing services, creating difficulties of security service recommendations in social fog computing. To address this, we propose a novel crowd sensing-enabling security service provisioning method to recommend security services accurately in social fog computing systems. Simulation results show the feasibilities and efficiency of the crowd sensing-enabling security service recommendation method for social fog computing systems. PMID:28758943

Neurobiological correlates of social functioning in autism.

Neuhaus, Emily; Beauchaine, Theodore P; Bernier, Raphael

2010-08-01

Although autism is defined by deficits in three areas of functioning (social, communicative, and behavioral), impairments in social interest and restricted behavioral repertoires are central to the disorder. As a result, a detailed understanding of the neurobiological systems subserving social behavior may have implications for prevention, early identification, and intervention for affected families. In this paper, we review a number of potential neurobiological mechanisms--across several levels of analysis--that subserve normative social functioning. These include neural networks, neurotransmitters, and hormone systems. After describing the typical functioning of each system, we review available empirical findings specific to autism. Among the most promising potential mechanisms of social behavioral deficits in autism are those involving neural networks including the amygdala, the mesocorticolimbic dopamine system, and the oxytocin system. Particularly compelling are explanatory models that integrate mechanisms across biological systems, such as those linking dopamine and oxytocin with brain regions critical to reward processing.

Social Novelty Investigation in the Juvenile Rat: Modulation by the μ-Opioid System.

PubMed

Smith, C J W; Wilkins, K B; Mogavero, J N; Veenema, A H

2015-10-01

The drive to approach and explore novel conspecifics is inherent to social animals and may promote optimal social functioning. Juvenile animals seek out interactions with novel peers more frequently and find these interactions to be more rewarding than their adult counterparts. In the present study, we aimed to establish a behavioural paradigm to measure social novelty-seeking in juvenile rats and to determine the involvement of the opioid, dopamine, oxytocin and vasopressin systems in this behaviour. To this end, we developed the social novelty preference test to assess the preference of a juvenile rat to investigate a novel over a familiar (cage mate) conspecific. We show that across the juvenile period both male and female rats spend more time investigating a novel conspecific than a cage mate, independent of subject sex or repeated exposure to the test. We hypothesised that brain systems subserving social information processing and social motivation/reward (i.e. the opioid, dopamine, oxytocin, vasopressin systems) might support social novelty preference. To test this, receptor antagonists of each of these systems were administered i.c.v. prior to exposure to the social novelty preference test and, subsequently, to the social preference test, to examine the specificity of these effects. We find that μ-opioid receptor antagonism reduces novel social investigation in both the social novelty preference and social preference tests while leaving the investigation of a cage mate (social novelty preference test) or an object (social preference test) unaffected. In contrast, central blockade of dopamine D2 receptors (with eticlopride), oxytocin receptors (with des-Gly-NH2,d(CH2)5[Tyr(Me)2,Thr4]OVT) or vasopressin V1a receptors [with (CH2)5Tyr(Me2)AVP] failed to alter social novelty preference or social preference. Overall, we have established a new behavioural test to study social novelty-seeking behaviour in the juvenile rat and show that the μ-opioid system facilitates this behaviour, possibly by reducing risk avoidance and enhancing the hedonic and/or motivational value of social novelty. © 2015 British Society for Neuroendocrinology.

Integrating Social impacts on Health and Health-Care Systems in Systemic Seismic Vulnerability Analysis

NASA Astrophysics Data System (ADS)

Kunz-Plapp, T.; Khazai, B.; Daniell, J. E.

2012-04-01

This paper presents a new method for modeling health impacts caused by earthquake damage which allows for integrating key social impacts on individual health and health-care systems and for implementing these impacts in quantitative systemic seismic vulnerability analysis. In current earthquake casualty estimation models, demand on health-care systems is estimated by quantifying the number of fatalities and severity of injuries based on empirical data correlating building damage with casualties. The expected number of injured people (sorted by priorities of emergency treatment) is combined together with post-earthquake reduction of functionality of health-care facilities such as hospitals to estimate the impact on healthcare systems. The aim here is to extend these models by developing a combined engineering and social science approach. Although social vulnerability is recognized as a key component for the consequences of disasters, social vulnerability as such, is seldom linked to common formal and quantitative seismic loss estimates of injured people which provide direct impact on emergency health care services. Yet, there is a consensus that factors which affect vulnerability and post-earthquake health of at-risk populations include demographic characteristics such as age, education, occupation and employment and that these factors can aggravate health impacts further. Similarly, there are different social influences on the performance of health care systems after an earthquake both on an individual as well as on an institutional level. To link social impacts of health and health-care services to a systemic seismic vulnerability analysis, a conceptual model of social impacts of earthquakes on health and the health care systems has been developed. We identified and tested appropriate social indicators for individual health impacts and for health care impacts based on literature research, using available European statistical data. The results will be used to develop a socio-physical model of systemic seismic vulnerability that enhances the further understanding of societal seismic risk by taking into account social vulnerability impacts for health and health-care system, shelter, and transportation.

Objectives. To critically analyze social work’s role in Medicaid reform. Methods. We conducted semistructured interviews with 46 stakeholders from 10 US states that use a range of Medicaid reform approaches. We identified participants using snowball and purposive sampling. We gathered data in 2016 and analyzed them using qualitative methods. Results. Multiple themes emerged: (1) social work participates in Medicaid reform through clinical practice, including care coordination and case management; (2) there is a gap between social work’s practice-level and systems-level involvement in Medicaid innovations; (3) factors hindering social work’s involvement in systems-level practice include lack of visibility, insufficient clarity on social work’s role and impact, and too few resources within professional organizations; and (4) social workers need more training in health transformation payment models and policy. Conclusions. Social workers have unique skills that are valuable to building health systems that promote population health and reduce health inequities. Although there is considerable opportunity for social work to increase its role in Medicaid reform, there is little social work involvement at the systems level. PMID:29236537

The European Union Policy in the Field of Rare Diseases.

Rare diseases, are defined by the European Union as life-threatening or chronically debilitating diseases with low prevalence (less than 5 per 10,000). The specificities of rare diseases - limited number of patients and scarcity of relevant knowledge and expertise - single them out as a unique domain of very high European added-value.The legal instruments at the disposal of the European Union, in terms of the Article 168 of the Treaties, are very limited. However a combination of instruments using the research and the pharmaceutical legal basis and an intensive and creative use of funding from the Health Programmes has permitted to create a solid basis that Member States have considered enough to put rare diseases in a privileged position in the health agenda.The adoption of the Commission Communication, in November 2008, and of the Council Recommendation, in June 2009, and in 2011 the adoption of the Directive on Cross-border healthcare., have created an operational framework to act in the field of rare disease with European coordination in several areas (classification and codification, European Reference Networks, orphan medicinal products, the Commission expert group on rare diseases, etc.).Rare diseases is an area with high and practical potential for the European cooperation.

Characteristics of DC electric fields at dipolarization fronts

Laakso, Harri; Escoubet, Philippe; Masson, Arnaud

2016-04-01

We investigate the characteristics of DC electric field at dipolarization fronts and BBF's using multi-point Cluster observations. There are plenty of important issues that are considered, such as what kind of DC electric fields exist in such events and what are their spatial scales. One can also recognize if electrons and ions perform ExB drift motions in these events. To investigate this, we take an advantage of five different DC electric field measurements in the plasma sheet available from the EFW double probe experiment, EDI electron drift instrument, CODIF and HIA ion spectrometers, and PEACE electron spectrometer. The calibrated observations of the three spectrometers are used to determine the proton and electron drift velocity and furthermore the DC electric field, assuming that the electron and proton velocity perpendicular to the magnetic field is dominated by the ExB drift motion. Naturally when ions and electrons do not perform a proper drift motion, which can happen in the plasma sheet, the estimated DC electric field from ion and electron motion is not correct. However, surprisingly often the DC electric fields estimated from electron and ion motions are identical suggesting that this field is a real DC electric field around the measurement point. This investigation also helps understand how well different measurements are calibrated.

Crimes against humanity by Nazi Germany led to the codification of procedures for trying medical professionals. The principles detailed in the Nuremberg Code formulated by the Allies represented their effort to prevent future excesses and embody today's Institutional Review Boards. Reactive arthritis is often termed Reiter's syndrome, after Hans Reiter, who was incarcerated at Nuremberg. The authors reviewed Dr Hans Reiter's Nuremberg file at the National Archives in Washington, DC, and present chronologic excerpts of his interrogations between 1945 and 1947, with interpretative commentary. Reiter was involved with or knowledgeable of involuntary sterilization and euthanasia undertaken by the Nazi regime. He also played an active role in the design of a study that inoculated concentration camp internees at Buchenwald with an experimental typhus vaccine, which resulted in hundreds of deaths. A brilliant investigator and erudite intellectual, the career of Hans Reiter shows the importance and the relevance of scientific inquiry to adhere to principles enumerated in the Nuremberg Code. Because he was not the first to describe reactive arthritis, and in view of the above, Reiter's syndrome should only be used to cite an older reference that uses the term or in a historical context.

From Biological to Program Efficacy: Promoting Dialogue among the Research, Policy, and Program Communities12

The biological efficacy of nutritional supplements to complement usual diets in poor populations is well established. This knowledge rests on decades of methodologic research development and, more recently, on codification of methods to compile and interpret results across studies. The challenge now is to develop implementation (delivery) science knowledge and achieve a similar consensus on efficacy criteria for the delivery of these nutrients by public health and other organizations. This requires analysis of the major policy instruments for delivery and well-designed program delivery studies that examine the flow of a nutrient through a program impact pathway. This article discusses the differences between biological and program efficacy, and why elucidating the fidelity of delivery along the program impact pathways is essential for implementing a program efficacy trial and for assessing its internal and external validity. Research on program efficacy is expanding, but there is a lack of adequate frameworks to facilitate the process of harmonizing concepts and vocabulary, which is essential for communication among scientists, policy planners, and program implementers. There is an urgent need to elaborate these frameworks at national and program levels not only for program efficacy studies but also for the broader research agenda to support and improve the science of delivering adequate nutrition to those who need it most.

The business of ethics: gender, medicine, and the professional codification of the American Physiotherapy Association, 1918-1935.

PubMed

Linker, Beth

2005-07-01

The history of codes of ethics in health care has almost exclusively been told as a story of how medical doctors developed their own professional principles of conduct. Yet telling the history of medical ethics solely from the physicians' perspective neglects not only the numerous allied health care workers who developed their own codes of ethics in tandem with the medical profession, but also the role that gender played in the writing of such professional creeds. By focusing on the predominantly female organization of the American Physiotherapy Association (APA) and its 1935 "Code of Ethics and Discipline," I demonstrate how these women used their creed to at once curry favor from and challenge the authority of the medical profession. Through their Code, APA therapists engaged in a dynamic dialogue with the male physicians of the American Medical Association (AMA) in the name of professional survival. I conclude that, contrary to historians and philosophers who contend that professional women have historically operated under a gender-specific ethic of care, the physiotherapists avoided rhetoric construed as feminine and instead created a "business-like" creed in which they spoke solely about their relationship with physicians and remained silent on the matter of patient care.

Medical law is a scientific discipline which has not been affirmed in our country, but at law schools in many developed countries it has gained the status of a separate scientific discipline and today it is studied with multidisciplinary cooperation of Schools of Medicine, Schools of Dentistry and Schools of Pharmacy. Generally speaking, medical law concerns the rights and duties of the medical profession. The progress of scientific research and of new technology used in diagnostics and treatment, opens new fields in terms of responsibility. Most European countries have legal institutions in the field of health care. These include laws and legal acts, as well as codification of professional norms. Apart from the national law, there is also an international law concerning physisians. The World Health Organization and the World Association of Medical Doctors brought the following declarations: Declaration on Promotion of Patients' Rights, the Revised Lisbon Declaration on Patients' Rights, the Revised Helsinki Declaration on Biomedical Research Involving Human Subjects and the Council of Europe's Convention on Human Rights and Biomedicine. There is no national order of physicians in Serbia and Montenegro, because chambers of physicians with legal authority and mandatory membership have not been formed. The foundation of Chambers of Physicians of Vojvodina and Montenegro is the first step to goal achieving.

The unconscious often appears in the form of a question or answer to the difficult relationship between the psyche and culture, a difficulty that becomes exacerbated when we are dealing with cultural difference. This difficulty, evidenced for example by Freud's thoughts on Islam, reappears, albeit in a very different way, in ethnopsychiatric theory. The author discusses the blind spots of the binary logic of the unconscious present in the work of George Devereux, a logic that eventually leads him into the same trap he had himself criticized. This discussion allows us to open up other perspectives, by moving away from the analogies, confusions and splits between the psyche and culture towards what binds them together. This link is sustained by language and its dialectics, at the crossroads of individual singularity and cultural codifications. The author's approach is supported by two clinical vignettes: one from a case of a young Turkish woman, the other concerning a male Iraqi patient, a survivor of torture. This approach distances itself from any psychocentric view that would see the psyche as closed upon itself and thus ultimately exclude any object-relations and inter-subjective relationships; likewise, it rejects the ethnocentric conflation of the subject with his culture.

A central goal of behavioral medicine is the creation of evidence-based interventions for promoting behavior change. Scientific knowledge about behavior change could be more effectively accumulated using "ontologies." In information science, an ontology is a systematic method for articulating a "controlled vocabulary" of agreed-upon terms and their inter-relationships. It involves three core elements: (1) a controlled vocabulary specifying and defining existing classes; (2) specification of the inter-relationships between classes; and (3) codification in a computer-readable format to enable knowledge generation, organization, reuse, integration, and analysis. This paper introduces ontologies, provides a review of current efforts to create ontologies related to behavior change interventions and suggests future work. This paper was written by behavioral medicine and information science experts and was developed in partnership between the Society of Behavioral Medicine's Technology Special Interest Group (SIG) and the Theories and Techniques of Behavior Change Interventions SIG. In recent years significant progress has been made in the foundational work needed to develop ontologies of behavior change. Ontologies of behavior change could facilitate a transformation of behavioral science from a field in which data from different experiments are siloed into one in which data across experiments could be compared and/or integrated. This could facilitate new approaches to hypothesis generation and knowledge discovery in behavioral science.

Technology and complex techniques are inevitably playing an increasing role in intensive care units. They continue to characterize nursing care and in some cases dehumanize it. The general aim of this study was to stimulate reflection on nursing care. The study was based on the participation of the investigators with the goal of producing changes in nursing practice. Qualitative methodology in the form of participatory action research and the Kemmis and McTaggart method were used. Data were collected through systematic observation, seven group meetings and document analysis. Eight nurses took part in the study. The meetings were recorded and transcribed verbatim into a computer. This process and the meaning of the verbatim transcription (codification/categorization process and document synthesis cards) were analyzed. The results of this study enabled exploration of the change in nursing practice and showed that the reflection in action method stimulates changes in practice. The new way of conceiving nursing action has increased nursing care quality and its humanization since it shows greater respect for the patient, provides families with closer contact and greater support, improves coordination of nursing care acts and increases collaboration among professionals.In conclusion, participatory action research is a valid and appropriate method that nurses can use to modify their daily practice.

Self-reference and predictive, normative and prescriptive approaches in applications of systems thinking in social sciences—(Survey)

2000-05-01

Cybernetics, systems thinking or systems theory, have been viewed as instruments of enhancing predictive, normative and prescriptive capabilities of the social sciences, beginning from microscale-management and ending with various reference to the global system. Descriptions, explanations and predictions achieved thanks to various systems ideas were also viewed as supportive for potential governance of social phenomena. The main aim of the paper is to examine what could be the possible applications of modern systems thinking in predictive, normative and prescriptive approaches in modern social sciences, beginning from management theory and ending with global studies. Attention is paid not only to "classical" mathematical systems models but also to the role of predictive, normative and prescriptive interpretations of analogies and metaphors associated with application of the classical ("first order cybernetics") and modern ("second order cybernetics", "complexity theory") systems thinking in social sciences.

EO Domain Specific Knowledge Enabled Services (KES-B)

This paper recovers and describes a number of major statements with respect to the vision, mission and technological approaches of the Technological Research Project (TRP) "EO Domain Specific Knowledge Enabled Services" (project acronym KES-B), which is currently under development at the European Space Research Institute (ESRIN) under contract "16397/02/I- SB". Resulting from the on-going R&D activities, the KES-B project aims are to demonstrate with a prototype system the feasibility of the application of innovative knowledge-based technologies to provide services for easy, scheduled and controlled exploitation of EO resources (e.g.: data, algorithms, procedures, storage, processors, ...), to automate the generation of products, and to support users in easily identifying and accessing the required information or products by using their own vocabulary, domain knowledge and preferences. The ultimate goals of KES-B are summarized in the provision of the two main types of KES services: 1st the Search service (also referred to as Product Exploitation or Information Retrieval; and 2nd the Production service (also referred to as Information Extraction), with the strategic advantage that they are enabled by Knowledge consolidated (formalized) within the system. The KES-B system technical solution approach is driven by a strong commitment for the adoption of industry (XML-based) language standards, aiming to have an interoperable, scalable and flexible operational prototype. In that sense, the Search KES services builds on the basis of the adoption of consolidated and/or emergent W3C semantic-web standards. Remarkably the languages/models Dublin Core (DC), Universal Resource Identifier (URI), Resource Description Framework (RDF) and Ontology Web Language (OWL), and COTS like Protege [1] and JENA [2] are being integrated in the system as building bricks for the construction of the KES based Search services. On the other hand, the Production KES services builds on top of workflow management standards and tools. In this side, the Business Process Execution Language (BPEL), the Web Services Definition Language (WSDL), and the Collaxa [3] COTS tool for workflow management are being integrated for the construction of the KES-B Production Services. The KES-B platform (web portal and web-server) architecture is build on the basis of the J2EE reference architecture. These languages represent the mean for the codification of the different types of knowledge that are to be formalized in the system. This representing the ontological architecture of the system. This shall enable in fact the interoperability with other KES-based systems committing as well to those standards. The motivation behind this vision is pointing towards the construction of the Semantic-web based GRID supply- chain infrastructure for EO-services, in line with the INSPIRE initiative suggestions.

Objective The present study tested the hypothesis that low behavioral approach system (BAS) sensitivity is associated with social anxiety in combat veterans. Method Self-report measures of reinforcement sensitivity, combat exposure, social interaction anxiety, and social observation anxiety were administered to 197 Iraq/Afghanistan combat veterans. Results As expected, combat exposure, behavioral inhibition system (BIS) sensitivity, and fight-flight-freeze system (FFFS) sensitivity were positively associated with both social interaction anxiety and social observation anxiety. In contrast, BAS sensitivity was negatively associated with social interaction anxiety only. An analysis of the BAS subscales revealed that the Reward Responsiveness subscale was the only BAS subscale associated with social interaction anxiety. BAS-Reward Responsiveness was also associated with social observation anxiety. Conclusion The findings from the present research provide further evidence that low BAS sensitivity may be associated with social anxiety over and above the effects of BIS and FFFS sensitivity.

Social-ecological resilience and social conflict: institutions and strategic adaptation in Swedish water management.

PubMed

Galaz, Victor

2005-11-01

Dealing with uncertainty and complexity in social-ecological systems is profoundly dependent on the ability of natural resource users to learn and adapt from ecological surprises and crises. This paper analyzes why and how learning processes are affected by strategic behavior among natural resource users and how social conflict is affected by social and ecological uncertainty. The claim is that social conflict among natural resource users seriously inhibits the possibilities of learning and adaptation in social-ecological systems. This is done combining insights from political science, experimental economics, and social-psychology and an analytical case study elaborating social conflict and institutional change in Swedish water management institutions. This paper also discusses the crucial role the institutional context plays in defining the outcome of learning processes in Swedish water management institutions and hence highlights previously poorly elaborated political aspects of learning processes and institutional change in social-ecological systems.

The paper describes the social capital study for a system where actors are engaged in an economic activity. The focus is on the analysis of communications structural parameters (transactions) between the actors. Comparison between transaction network graph structure and the structure of a random Bernoulli graph of the same dimension and density allows revealing specific structural features of the economic system under study. Structural analysis is based on SNA-methodology (SNA - Social Network Analysis). It is shown that structural parameter values of the graph formed by agent relationship links may well characterize different aspects of the social capital structure. The research advocates that it is useful to distinguish the difference between each agent social capital and the whole system social capital.

In the field of social neuroscience, major branches of research have been instrumental in describing independent components of typical and aberrant social information processing, but the field as a whole lacks a comprehensive model that integrates different branches. We review existing research related to the neural basis of three key neural systems underlying social information processing: social perception, action observation, and theory of mind. We propose an integrative model that unites these three processes and highlights the posterior superior temporal sulcus (pSTS), which plays a central role in all three systems. Furthermore, we integrate these neural systems with the dual system account of implicit and explicit social information processing. Large-scale meta-analyses based on Neurosynth confirmed that the pSTS is at the intersection of the three neural systems. Resting-state functional connectivity analysis with 1000 subjects confirmed that the pSTS is connected to all other regions in these systems. The findings presented in this review are specifically relevant for psychiatric research especially disorders characterized by social deficits such as autism spectrum disorder.

Mirror Neuron System and Mentalizing System connect during online social interaction.

Two sets of brain areas are repeatedly reported in neuroimaging studies on social cognition: the Mirror Neuron System and the Mentalizing System. The Mirror System is involved in goal understanding and has been associated with several emotional and cognitive functions central to social interaction, ranging from empathy to gestural communication and imitation. The Mentalizing System is recruited in tasks requiring cognitive processes such as self-reference and understanding of other's intentions. Although theoretical accounts for an interaction between the two systems have been proposed, little is known about their synergy during social exchanges. In order to explore this question, we have recorded brain activity by means of functional MRI during live social exchanges based on reciprocal imitation of hand gestures. Here, we investigate, using the method of psychophysiological interaction, the changes in functional connectivity of the Mirror System due to the conditions of interest (being imitated, imitating) compared with passive observation of hand gestures. We report a strong coupling between the Mirror System and the Mentalizing System during the imitative exchanges. Our findings suggest a complementary role of the two networks during social encounters. The Mirror System would engage in the preparation of own actions and the simulation of other's actions, while the Mentalizing System would engage in the anticipation of the other's intention and thus would participate to the co-regulation of reciprocal actions. Beyond a specific effect of imitation, the design used offers the opportunity to tackle the role of role-switching in an interpersonal account of social cognition.

Mere exposure to money increases endorsement of free-market systems and social inequality.

2013-05-01

The present research tested whether incidental exposure to money affects people's endorsement of social systems that legitimize social inequality. We found that subtle reminders of the concept of money, relative to nonmoney concepts, led participants to endorse more strongly the existing social system in the United States in general (Experiment 1) and free-market capitalism in particular (Experiment 4), to assert more strongly that victims deserve their fate (Experiment 2), and to believe more strongly that socially advantaged groups should dominate socially disadvantaged groups (Experiment 3). We further found that reminders of money increased preference for a free-market system of organ transplants that benefited the wealthy at the expense of the poor even though this was not the prevailing system (Experiment 5) and that this effect was moderated by participants' nationality. These results demonstrate how merely thinking about money can influence beliefs about the social order and the extent to which people deserve their station in life.

With the growing popularity of the online social platform, the social network based approaches to recommendation emerged. However, because of the open nature of rating systems and social networks, the social recommender systems are susceptible to malicious attacks. In this paper, we present a certain novel attack, which inherits characteristics of the rating attack and the relation attack, and term it hybrid attack. Furtherly, we explore the impact of the hybrid attack on model-based social recommender systems in multiple aspects. The experimental results show that, the hybrid attack is more destructive than the rating attack in most cases. In addition, users and items with fewer ratings will be influenced more when attacked. Last but not the least, the findings suggest that spammers do not depend on the feedback links from normal users to become more powerful, the unilateral links can make the hybrid attack effective enough. Since unilateral links are much cheaper, the hybrid attack will be a great threat to model-based social recommender systems.

Social isolation reduces serotonergic fiber density in the inferior colliculus of female, but not male, mice.

Early-life experiences, including maternal deprivation and social isolation during adolescence, have a profound influence on a range of adult social behaviors. Post-weaning social isolation in rodents influences behavior in part through the alteration of neuromodulatory systems, including the serotonergic system. Of significance to social behavior, the serotonergic system richly innervates brain areas involved in vocal communication, including the auditory system. However, the influence of isolation on serotonergic input to the auditory system remains underexplored. Here, we assess whether 4 weeks of post-weaning individual housing alters serotonergic fiber density in the inferior colliculus (IC), an auditory midbrain nucleus in which serotonin alters auditory-evoked activity. Individually housed male and female mice were compared to conspecifics housed socially in groups of three. Serotonergic projections were subsequently visualized with an antibody to the serotonin transporter, which labels serotonergic fibers with relatively high selectivity. Fiber densities were estimated in the three major subregions of the IC using line-scan intensity analysis. Individually housed female mice showed a significantly reduced fiber density relative to socially housed females, which was accompanied by a lower body weight in individually housed females. In contrast, social isolation did not affect serotonergic fiber density in the IC of males. This finding suggests that sensitivity of the serotonergic system to social isolation is sex-dependent, which could be due to a sex difference in the effect of isolation on psychosocial stress. Since serotonin availability depends on social context, this finding further suggests that social isolation can alter the acute social regulation of auditory processing. Copyright © 2018.

Healthcare systems are organized following one of two basic models: social security systems, which link access to health services to labor status, and national health systems, which grant access to health as a citizen's right. Mexico adopted, since the institutionalization of social security and healthcare services in 1943, a mixed system. Social security institutions covered the salaried workers and public assistance was granted to the remaining of the population. At the beginning of the XXI century the Mexican health system entered a crisis as the conditions to expand health coverage through social security were not met and public assistance services were insufficient. In order to address these developments, the Healthcare Social Protection System was founded (2004) as a mechanism to effectively guarantee every person's right to health as established after the constitutional amendment of article fourth in 1983. Seguro Popular is the mechanism that through federal and states' contributions seeks to financially protect the population without access to social security's health services, and thus prevent impoverishment due to out of pocket and catastrophic health expenditures.

Social Buffering of Stress in Development: A Career Perspective

PubMed Central

Gunnar, Megan R.

2016-01-01

This review provides a broad overview of my research group's work on social buffering in human development in the context of the field. Much of the focus is on social buffering of the hypothalamic-pituitary-adrenocortical (HPA) system, one of the two major arms of the mammalian stress system. This focus reflects the centrality of the HPA system in research on social buffering in the fields of developmental psychobiology and developmental science. However, buffering of the cardiovascular and autonomic nervous system is also discussed. The central developmental question in this area derives from attachment theory which argues that the infant's experience of stress and arousal regulation in the context of her early attachment relationships is not an immature form of social buffering experienced in adulthood, but rather the foundation out of which individual differences in the capacity to gain stress relief from social partners emerge. The emergence of social buffering in infancy, changes in social buffering throughout childhood and adolescence, the influence of early experience on later individual differences in social buffering, and critical gaps in our knowledge are described.

Social skills probably emerge from the interaction between different neural processing levels. However, social neuroscience is fragmented into highly specialized, rarely cross-referenced topics. The present study attempts a systematic reconciliation by deriving a social brain definition from neural activity meta-analyses on social-cognitive capacities. The social brain was characterized by meta-analytic connectivity modeling evaluating coactivation in task-focused brain states and physiological fluctuations evaluating correlations in task-free brain states. Network clustering proposed a functional segregation into (1) lower sensory, (2) limbic, (3) intermediate, and (4) high associative neural circuits that together mediate various social phenomena. Functional profiling suggested that no brain region or network is exclusively devoted to social processes. Finally, nodes of the putative mirror-neuron system were coherently cross-connected during tasks and more tightly coupled to embodied simulation systems rather than abstract emulation systems. These first steps may help reintegrate the specialized research agendas in the social and affective sciences. © The Author 2017. Published by Oxford University Press. All rights reserved.

A novel system for tracking social preference dynamics in mice reveals sex- and strain-specific characteristics.

Netser, Shai; Haskal, Shani; Magalnik, Hen; Wagner, Shlomo

2017-01-01

Deciphering the biological mechanisms underlying social behavior in animal models requires standard behavioral paradigms that can be unbiasedly employed in an observer- and laboratory-independent manner. During the past decade, the three-chamber test has become such a standard paradigm used to evaluate social preference (sociability) and social novelty preference in mice. This test suffers from several caveats, including its reliance on spatial navigation skills and negligence of behavioral dynamics. Here, we present a novel experimental apparatus and an automated analysis system which offer an alternative to the three-chamber test while solving the aforementioned caveats. The custom-made apparatus is simple for production, and the analysis system is publically available as an open-source software, enabling its free use. We used this system to compare the dynamics of social behavior during the social preference and social novelty preference tests between male and female C57BL/6J mice. We found that in both tests, male mice keep their preference towards one of the stimuli for longer periods than females. We then employed our system to define several new parameters of social behavioral dynamics in mice and revealed that social preference behavior is segregated in time into two distinct phases. An early exploration phase, characterized by high rate of transitions between stimuli and short bouts of stimulus investigation, is followed by an interaction phase with low transition rate and prolonged interactions, mainly with the preferred stimulus. Finally, we compared the dynamics of social behavior between C57BL/6J and BTBR male mice, the latter of which are considered as asocial strain serving as a model for autism spectrum disorder. We found that BTBR mice ( n  = 8) showed a specific deficit in transition from the exploration phase to the interaction phase in the social preference test, suggesting a reduced tendency towards social interaction. We successfully employed our new experimental system to unravel previously unidentified sex- and strain-specific differences in the dynamics of social behavior in mice. Thus, the system presented here facilitates a more thorough and detailed analysis of social behavior in small rodent models, enabling a better comparison between strains and treatments.

The Role of the Individual in the Social Information Process

NASA Astrophysics Data System (ADS)

Fuchs, Christian

2003-03-01

The aim of this paper is to point out which role the individual plays in the generation of information in social systems. First, it is argued that the individual is a social, self-conscious, creative, reflective, cultural, symbol- and language-using, active natural, producing, labouring, objective, corporeal, living, real, sensuous, visionary, imaginative, designing, co-operative being that makes its own history and can strive towards freedom and autonomy. Based on these assumptions the re-creation/self-organisation of social systems is described as a dialectic of actions and social structures and as a dialectic of individual information and social information. The individual enters economic, political and cultural relationships that result in the emergence and differentiation of social (i.e. economic, political and cultural) information which enables and constrains individual actions and thinking. Individuals as actors in social systems are indispensable for social self-organisation.

Exploring the Role of Social Memory of Floods for Designing Flood Early Warning Operations

Girons Lopez, Marc; Di Baldassarre, Giuliano; Grabs, Thomas; Halldin, Sven; Seibert, Jan

2016-04-01

Early warning systems are an important tool for natural disaster mitigation practices, especially for flooding events. Warnings rely on near-future forecasts to provide time to take preventive actions before a flood occurs, thus reducing potential losses. However, on top of the technical capacities, successful warnings require an efficient coordination and communication among a range of different actors and stakeholders. The complexity of integrating the technical and social spheres of warning systems has, however, resulted in system designs neglecting a number of important aspects such as social awareness of floods thus leading to suboptimal results. A better understanding of the interactions and feedbacks among the different elements of early warning systems is therefore needed to improve their efficiency and therefore social resilience. When designing an early warning system two important decisions need to be made regarding (i) the hazard magnitude at and from which a warning should be issued and (ii) the degree of confidence required for issuing a warning. The first decision is usually taken based on the social vulnerability and climatic variability while the second one is related to the performance (i.e. accuracy) of the forecasting tools. Consequently, by estimating the vulnerability and the accuracy of the forecasts, these two variables can be optimized to minimize the costs and losses. Important parameters with a strong influence on the efficiency of warning systems such as social awareness are however not considered in their design. In this study we present a theoretical exploration of the impact of social awareness on the design of early warning systems. For this purpose we use a definition of social memory of flood events as a proxy for flood risk awareness and test its effect on the optimization of the warning system design variables. Understanding the impact of social awareness on warning system design is important to make more robust warnings that can better adapt to different social settings and more efficiently reduce vulnerability.

Methodology to explore interactions between the water system and society in order to identify adaptation strategies

Offermans, A. G. E.; Haasnoot, M.

2009-04-01

Development of sustainable water management strategies involves analysing current and future vulnerability, identification of adaptation possibilities, effect analysis and evaluation of the strategies under different possible futures. Recent studies on water management often followed the pressure-effect chain and compared the state of social, economic and ecological functions of the water systems in one or two future situations with the current situation. The future is, however, more complex and dynamic. Water management faces major challenges to cope with future uncertainties in both the water system as well as the social system. Uncertainties in our water system relate to (changes in) drivers and pressures and their effects on the state, like the effects of climate change on discharges. Uncertainties in the social world relate to changing of perceptions, objectives and demands concerning water (management), which are often related with the aforementioned changes in the physical environment. The methodology presented here comprises the 'Perspectives method', derived from the Cultural Theory, a method on analyzing and classifying social response to social and natural states and pressures. The method will be used for scenario analysis and to identify social responses including changes in perspectives and management strategies. The scenarios and responses will be integrated within a rapid assessment tool. The purpose of the tool is to provide users with insight about the interaction of the social and physical system and to identify robust water management strategies by analysing the effectiveness under different possible futures on the physical, social and socio-economic system. This method allows for a mutual interaction between the physical and social system. We will present the theoretical background of the perspectives method as well as a historical overview of perspective changes in the Dutch Meuse area to show how social and physical systems interrelate. We will also show how the integration of both can contribute to the identification of robust water management strategies.

Political socialization theory explains how an individual develops a political belief system. As the health care system undergoes dramatic changes, nursing faculty should use political socialization theory to enhance the education of student nurses. A political thread can be woven through the nursing curricula, and students can be socialized to the political role. The new generation of nurses must incorporate a political component into their professional role identity. Political socialization theory can guide nursing faculty as knowledge of the political system and political skills are incorporated into nursing curricula.

This paper discusses the changes in the social assistance component of social protection in the two decades that followed the 1988 Constitution. It discusses the transformations of social protection and social assistance in the past decades and the processes that in the 1990 s advanced the reform of social assistance policies in Brazil without, however, producing great changes in how services were delivered. By 2000 there had been a great expansion of resources as well as benefits and services coverage in social assistance. This paper argues that conditional cash transfer programs, though created and spread in an international context of restrictive policies, when integrated into Brazil s public and universal system of social assistance, substantively widened the scope of social protection. Some effects of the expansion in the Brazilian social protection system are identified: less income inequality; creation of an institutional capacity in the area of social assistance; the social, political and symbolic meaning of the inclusion of a large segment of the population in a public system of social assistance by means of a provision structure that does not belong to traditional devices of philanthropy and clientelism.

Feedbacks between conservation and social-ecological systems

Robust ways to meet objectives of environmental conservation and social and economic development remain elusive. This struggle may in part be related to insufficient understanding of the feedbacks between conservation initiatives and social-ecological systems, specifically, the ways in which conservation initiatives result in social changes that have secondary effects on the environments targeted by conservation. To explore this idea we sampled peer-reviewed articles addressing the social and environmental dimensions of conservation and coded each paper according to its research focus and characterization of these feedbacks. The majority of articles in our sample focused either on the effect of conservation initiatives on people (e.g., relocation, employment) or the effect of people on the environment (e.g., fragmentation, conservation efficacy of traditional management systems). Few studies in our sample empirically addressed both the social dynamics resulting from conservation initiatives and subsequent environmental effects. In many cases, one was measured and the other was discussed anecdotally. Among the studies that describe feedbacks between social and environmental variables, there was more evidence of positive (amplifying) feedbacks between social and environmental outcomes (i.e., undesirable social outcomes yielded undesirable environmental effects, and desirable social outcomes yielded desirable environmental effects). The major themes within the sampled literature include conflict between humans and wild animals, social movements, adaptive comanagement, loss of traditional management systems, traditional ecological knowledge, human displacement and risks to livelihoods, and conservation and development. The narratives associated with each theme can serve as hypotheses for facilitating further discussion about conservation issues and for catalyzing future studies of the feedbacks between conservation and social-ecological systems.

Social Intelligence in a Human-Machine Collaboration System

In this information society of today, it is often argued that it is necessary to create a new way of human-machine interaction. In this paper, an agent with social response capabilities has been developed to achieve this goal. There are two kinds of information that is exchanged by two entities: objective and functional information (e.g., facts, requests, states of matters, etc.) and subjective information (e.g., feelings, sense of relationship, etc.). Traditional interactive systems have been designed to handle the former kind of information. In contrast, in this study social agents handling the latter type of information are presented. The current study focuses on sociality of the agent from the view point of Media Equation theory. This article discusses the definition, importance, and benefits of social intelligence as agent technology and argues that social intelligence has a potential to enhance the user's perception of the system, which in turn can lead to improvements of the system's performance. In order to implement social intelligence in the agent, a mind model has been developed to render affective expressions and personality of the agent. The mind model has been implemented in a human-machine collaborative learning system. One differentiating feature of the collaborative learning system is that it has an agent that performs as a co-learner with which the user interacts during the learning session. The mind model controls the social behaviors of the agent, thus making it possible for the user to have more social interactions with the agent. The experiment with the system suggested that a greater degree of learning was achieved when the students worked with the co-learner agent and that the co-learner agent with the mind model that expressed emotions resulted in a more positive attitude toward the system.

Contact structure, mobility, environmental impact and behaviour: the importance of social forces to infectious disease dynamics and disease ecology.

Human factors, including contact structure, movement, impact on the environment and patterns of behaviour, can have significant influence on the emergence of novel infectious diseases and the transmission and amplification of established ones. As anthropogenic climate change alters natural systems and global economic forces drive land-use and land-cover change, it becomes increasingly important to understand both the ecological and social factors that impact infectious disease outcomes for human populations. While the field of disease ecology explicitly studies the ecological aspects of infectious disease transmission, the effects of the social context on zoonotic pathogen spillover and subsequent human-to-human transmission are comparatively neglected in the literature. The social sciences encompass a variety of disciplines and frameworks for understanding infectious diseases; however, here we focus on four primary areas of social systems that quantitatively and qualitatively contribute to infectious diseases as social-ecological systems. These areas are social mixing and structure, space and mobility, geography and environmental impact, and behaviour and behaviour change. Incorporation of these social factors requires empirical studies for parametrization, phenomena characterization and integrated theoretical modelling of social-ecological interactions. The social-ecological system that dictates infectious disease dynamics is a complex system rich in interacting variables with dynamically significant heterogeneous properties. Future discussions about infectious disease spillover and transmission in human populations need to address the social context that affects particular disease systems by identifying and measuring qualitatively important drivers.This article is part of the themed issue 'Opening the black box: re-examining the ecology and evolution of parasite transmission'. © 2017 The Author(s).

Neuroendocrine control in social relationships in non-human primates: Field based evidence.

PubMed

Ziegler, Toni E; Crockford, Catherine

2017-05-01

Primates maintain a variety of social relationships and these can have fitness consequences. Research has established that different types of social relationships are unpinned by different or interacting hormonal systems, for example, the neuropeptide oxytocin influences social bonding, the steroid hormone testosterone influences dominance relationships, and paternal care is characterized by high oxytocin and low testosterone. Although the oxytocinergic system influences social bonding, it can support different types of social bonds in different species, whether pair bonds, parent-offspring bonds or friendships. It seems that selection processes shape social and mating systems and their interactions with neuroendocrine pathways. Within species, there are individual differences in the development of the neuroendocrine system: the social environment individuals are exposed to during ontogeny alters their neuroendocrine and socio-cognitive development, and later, their social interactions as adults. Within individuals, neuroendocrine systems can also have short-term effects, impacting on social interactions, such as those during hunting, intergroup encounters or food sharing, or the likelihood of cooperating, winning or losing. To understand these highly dynamic processes, extending research beyond animals in laboratory settings to wild animals living within their natural social and ecological setting may bring insights that are otherwise unreachable. Field endocrinology with neuropeptides is still emerging. We review the current status of this research, informed by laboratory studies, and identify questions particularly suited to future field studies. We focus on primate social relationships, specifically social bonds (mother-offspring, father-offspring, cooperative breeders, pair bonds and adult platonic friendships), dominance, cooperation and in-group/out-group relationships, and examine evidence with respect to the 'tend and defend' hypothesis.

Monitoring caustic injuries from emergency department databases using automatic keyword recognition software.

In Italy the European Union Injury Database reports the involvement of chemical products in 0.9% of home and leisure accidents. The Emergency Department registry on domestic accidents in Italy and the Poison Control Centres record that 90% of cases of exposure to toxic substances occur in the home. It is not rare for the effects of chemical agents to be observed in hospitals, with a high potential risk of damage - the rate of this cause of hospital admission is double the domestic injury average. The aim of this study was to monitor the effects of injuries caused by caustic agents in Italy using automatic free-text recognition in Emergency Department medical databases. We created a Stata software program to automatically identify caustic or corrosive injury cases using an agent-specific list of keywords. We focused attention on the procedure's sensitivity and specificity. Ten hospitals in six regions of Italy participated in the study. The program identified 112 cases of injury by caustic or corrosive agents. Checking the cases by quality controls (based on manual reading of ED reports), we assessed 99 cases as true positive, i.e. 88.4% of the patients were automatically recognized by the software as being affected by caustic substances (99% CI: 80.6%- 96.2%), that is to say 0.59% (99% CI: 0.45%-0.76%) of the whole sample of home injuries, a value almost three times as high as that expected (p < 0.0001) from European codified information. False positives were 11.6% of the recognized cases (99% CI: 5.1%- 21.5%). Our automatic procedure for caustic agent identification proved to have excellent product recognition capacity with an acceptable level of excess sensitivity. Contrary to our a priori hypothesis, the automatic recognition system provided a level of identification of agents possessing caustic effects that was significantly much greater than was predictable on the basis of the values from current codifications reported in the European Database.

Structural materials challenges for advanced reactor systems

NASA Astrophysics Data System (ADS)

Yvon, P.; Carré, F.

2009-03-01

Key technologies for advanced nuclear systems encompass high temperature structural materials, fast neutron resistant core materials, and specific reactor and power conversion technologies (intermediate heat exchanger, turbo-machinery, high temperature electrolytic or thermo-chemical water splitting processes, etc.). The main requirements for the materials to be used in these reactor systems are dimensional stability under irradiation, whether under stress (irradiation creep or relaxation) or without stress (swelling, growth), an acceptable evolution under ageing of the mechanical properties (tensile strength, ductility, creep resistance, fracture toughness, resilience) and a good behavior in corrosive environments (reactor coolant or process fluid). Other criteria for the materials are their cost to fabricate and to assemble, and their composition could be optimized in order for instance to present low-activation (or rapid desactivation) features which facilitate maintenance and disposal. These requirements have to be met under normal operating conditions, as well as in incidental and accidental conditions. These challenging requirements imply that in most cases, the use of conventional nuclear materials is excluded, even after optimization and a new range of materials has to be developed and qualified for nuclear use. This paper gives a brief overview of various materials that are essential to establish advanced systems feasibility and performance for in pile and out of pile applications, such as ferritic/martensitic steels (9-12% Cr), nickel based alloys (Haynes 230, Inconel 617, etc.), oxide dispersion strengthened ferritic/martensitic steels, and ceramics (SiC, TiC, etc.). This article gives also an insight into the various natures of R&D needed on advanced materials, including fundamental research to investigate basic physical and chemical phenomena occurring in normal and accidental operating conditions, lab-scale tests to characterize candidate materials mechanical properties and corrosion resistance, as well as component mock-up tests on technology loops to validate potential applications while accounting for mechanical design rules and manufacturing processes. The selection, assessment and validation of materials necessitate a large number of experiments, involving rare and expensive facilities such as research reactors, hot laboratories or corrosion loops. The modelling and the codification of the behaviour of materials will always involve the use of such technological experiments, but it is of utmost importance to develop also a predictive material science. Finally, the paper stresses the benefit of prospects of multilateral collaboration to join skills and share efforts of R&D to achieve in the nuclear field breakthroughs on materials that have already been achieved over the past decades in other industry sectors (aeronautics, metallurgy, chemistry, etc.).

Experiential effects on mirror systems and social learning: implications for social intelligence.

Reader, Simon M

2014-04-01

Investigations of biases and experiential effects on social learning, social information use, and mirror systems can usefully inform one another. Unconstrained learning is predicted to shape mirror systems when the optimal response to an observed act varies, but constraints may emerge when immediate error-free responses are required and evolutionary or developmental history reliably predicts the optimal response. Given the power of associative learning, such constraints may be rare.

Measuring Social Relationships in Different Social Systems: The Construction and Validation of the Evaluation of Social Systems (EVOS) Scale

Social interactions have gained increasing importance, both as an outcome and as a possible mediator in psychotherapy research. Still, there is a lack of adequate measures capturing relational aspects in multi-person settings. We present a new measure to assess relevant dimensions of quality of relationships and collective efficacy regarding interpersonal interactions in diverse personal and professional social systems including couple partnerships, families, and working teams: the EVOS. Theoretical dimensions were derived from theories of systemic family therapy and organizational psychology. The study was divided in three parts: In Study 1 (N = 537), a short 9-item scale with two interrelated factors was constructed on the basis of exploratory factor analysis. Quality of relationship and collective efficacy emerged as the most relevant dimensions for the quality of social systems. Study 2 (N = 558) confirmed the measurement model using confirmatory factor analysis and established validity with measures of family functioning, life satisfaction, and working team efficacy. Measurement invariance was assessed to ensure that EVOS captures the same latent construct in all social contexts. In Study 3 (N = 317), an English language adaptation was developed, which again confirmed the original measurement model. The EVOS is a theory-based, economic, reliable, and valid measure that covers important aspects of social relationships, applicable for different social systems. It is the first instrument of its kind and an important addition to existing measures of social relationships and related outcome measures in therapeutic and other counseling settings involving multiple persons.

Social capital is an important resource that can be mobilized for purposive action or competitive gain. The distribution of social capital in social-ecological systems can determine who is more productive at extracting ecological resources and who emerges as influential in guiding their management, thereby empowering some while disempowering others. Despite its importance, the factors that contribute to variation in social capital among individuals have not been widely studied. We adopt a network perspective to examine what determines social capital among individuals in social-ecological systems. We begin by identifying network measures of social capital relevant for individuals in this context, and review existing evidence concerning their determinants. Using a complete social network dataset from Hawaii's longline fishery, we employ social network analysis and other statistical methods to empirically estimate these measures and determine the extent to which individual stakeholder attributes explain variation within them. We find that ethnicity is the strongest predictor of social capital. Measures of human capital (i.e., education, experience), years living in the community, and information-sharing attitudes are also important. Surprisingly, we find that when controlling for other factors, industry leaders and formal fishery representatives are generally not well connected. Our results offer new quantitative insights on the relationship between stakeholder diversity, social networks, and social capital in a coupled social-ecological system, which can aid in identifying barriers and opportunities for action to overcome resource management problems. Our results also have implications for achieving resource governance that is not only ecologically and economically sustainable, but also equitable.

2010-09-01

As systems evolve over time, their natural tendency is to become increasingly more complex. Studies in the field of complex systems have generated new perspectives on management in social organizations such as hospitals. Much of this research appears as a natural extension of the cross-disciplinary field of systems theory. This is the 15th in a series of articles applying complex systems science to the traditional management concepts of planning, organizing, directing, coordinating, and controlling. In this article, the authors discuss healthcare social networks as a hierarchy of embedded complex adaptive systems. The authors further examine the use of social network analysis tools as a means to understand complex communication patterns and reduce medical errors.

Transdisciplinary teams and ethical partnerships with communities and practitioners will be needed to responsibly develop high-quality innovative solutions. A useful next step would be to clarify to what extent factors that could "make or break" these partnerships arise from within versus outside of the field of social work and how this has changed over time. Advancing innovation in social work will mean making decisions in a complex, ever-changing system.

2016-01-01

In the late twentieth century, the bio-psycho-social framework emerged as a powerful influence on the conceptualisation and delivery of health and rehabilitation services including social work services in these fields. The bio-psycho-social framework is built on a systems view of health and well-being ( Garland and Howard, 2009). The systems perspective encourages medical and allied health professions, including social work, to recognise and to respond to the multiple systems impacting on individual health and well-being ( Engel, 2003). This paper analyses how advances in biomedical technology, particularly in the fields of neuroscience and human genomics, are challenging the bio-psycho-social approach to practice. The paper examines the pressures on the social work profession to embrace biomedical science and points to the problems in doing so. The conclusion points to some tentative ways forward for social workers to engage critically with biomedical advances and to strengthen the bio-psycho-social framework in the interests of holistic and ethical approaches to social work practice.

Social isolation and chronic handling alter endocannabinoid signaling and behavioral reactivity to context in adult rats

Social deprivation in early life disrupts emotionality and attentional processes in humans. Rearing rats in isolation reproduces some of these abnormalities, which are attenuated by daily handling. However, the neurochemical mechanisms underlying these responses remain poorly understood. We hypothesized that post-weaning social isolation alters the endocannabinoid system, a neuromodulatory system that controls emotional responding. We characterized behavioral consequences of social isolation and evaluated whether handling would reverse social isolation-induced alterations in behavioral reactivity to context and the endocannabinoid system. At weaning, pups were single or group housed and concomitantly handled or not handled daily until adulthood. Rats were tested in emotionality- and attentional-sensitive behavioral assays (open field, elevated plus maze, startle and prepulse inhibition). Cannabinoid receptor densities and endocannabinoid levels were quantified in a separate group of rats. Social isolation negatively altered behavioral responding. Socially-isolated rats that were handled showed less deficits in the open field, elevated plus maze, and prepulse inhibition tests. Social isolation produced site-specific alterations (supraoptic nucleus, ventrolateral thalamus, rostral striatum) in cannabinoid receptor densities compared to group rearing. Handling altered the endocannabinoid system in neural circuitry controlling emotional expression. Handling altered endocannabinoid content (prefrontal and piriform cortices, nucleus accumbens) and cannabinoid receptor densities (lateral globus pallidus, cingulate and piriform cortices, hippocampus) in a region-specific manner. Some effects of social isolation on the endocannabinoid system were moderated by handling. Isolates were unresponsive to handling-induced increases in cannabinoid receptor densities (caudal striatum, anterior thalamus), but were sensitive to handling-induced increases in endocannabinoid content (piriform cortex), compared to group-reared rats. Our findings suggest alterations in the endocannabinoid system may contribute to the abnormal isolate phenotype. Handling modifies the endocannabinoid system and behavioral reactivity to context, but surmounts only some effects of social isolation. These data implicate a pivotal role for the endocannabinoid system in stress adaptation and emotionality-related disturbances. PMID:20394803

Resilience in social insect infrastructure systems

PubMed Central

2016-01-01

Both human and insect societies depend on complex and highly coordinated infrastructure systems, such as communication networks, supply chains and transportation networks. Like human-designed infrastructure systems, those of social insects are regularly subject to disruptions such as natural disasters, blockages or breaks in the transportation network, fluctuations in supply and/or demand, outbreaks of disease and loss of individuals. Unlike human-designed systems, there is no deliberate planning or centralized control system; rather, individual insects make simple decisions based on local information. How do these highly decentralized, leaderless systems deal with disruption? What factors make a social insect system resilient, and which factors lead to its collapse? In this review, we bring together literature on resilience in three key social insect infrastructure systems: transportation networks, supply chains and communication networks. We describe how systems differentially invest in three pathways to resilience: resistance, redirection or reconstruction. We suggest that investment in particular resistance pathways is related to the severity and frequency of disturbance. In the final section, we lay out a prospectus for future research. Human infrastructure networks are rapidly becoming decentralized and interconnected; indeed, more like social insect infrastructures. Human infrastructure management might therefore learn from social insect researchers, who can in turn make use of the mature analytical and simulation tools developed for the study of human infrastructure resilience.

Social communication is among the core areas of impairment for children with Autism Spectrum Disorders (ASD). The training of social orientation is important for improving social communication of children with ASD. In recent years, technology-assisted ASD intervention had gained momentum due to its potential advantages in terms of precision, sustainability, flexibility and cost. In this paper, we propose a closed-loop autonomous computer system, named ASOTS, for training social orientation skills to young children with ASD. This system is designed to detect and track a child's attention in response to social orientation bids and help the child towards appropriate social orientation when needed. Response to name, an important social orientation skill, was used to demonstrate the functionality of the proposed system. Ten toddlers with ASD participated in a pilot user study to show whether the system could be used on young children who have been diagnosed with ASD. Another pilot user study with 10 TD infants tested whether this system has a potential to be applied for early detection for infants who were younger than the age when ASD diagnoses can be done. This was done intentionally to separately demonstrate utility and functionality for the clinical population of interest and to demonstrate functionality beyond current clinical identification capacity (i.e., infants). The results showed that the proposed system and the protocol were well tolerated by both groups, successfully captured young children's attention, and elicited the desired behavior.

Communication and cognition: the social beyond language, interaction and culture.

PubMed

Mascareño, Aldo

2008-06-01

Cognition theories describe the social with terms like language, interaction or culture, whose theoretical status has also been discussed in modern sociology. These concepts are not well-positioned to understand the emergence and autonomy of social orders. Sociological theory of self-referential systems can be useful to reconstruct the bottom-up process which contributes to the emergence of the social as communication as well as to describe the way in which society exerts downward causation upon cognitive phenomena. The core of this theory is the systemic category of meaning as a shared horizon for psychic and social systems.

Pineda, Jaime A.; Ramachandran, Vilayanur S.

2007-01-01

The discovery of the mirror neuron system (MNS) has led researchers to speculate that this system evolved from an embodied visual recognition apparatus in monkey to a system critical for social skills in humans. It is accepted that the MNS is specialized for processing animate stimuli, although the degree to which social interaction modulates the firing of mirror neurons has not been investigated. In the current study, EEG mu wave suppression was used as an index of MNS activity. Data were collected while subjects viewed four videos: (1) Visual White Noise: baseline, (2) Non-interacting: three individuals tossed a ball up in the air to themselves, (3) Social Action, Spectator: three individuals tossed a ball to each other and (4) Social Action, Interactive: similar to video 3 except occasionally the ball would be thrown off the screen toward the viewer. The mu wave was modulated by the degree of social interaction, with the Non-interacting condition showing the least suppression, followed by the Social Action, Spectator condition and the Social Action, Interactive condition showing the most suppression. These data suggest that the human MNS is specialized not only for processing animate stimuli, but specifically stimuli with social relevance. PMID:18985120

Why Social Relationships Are Important for Physical Health: A Systems Approach to Understanding and Modifying Risk and Protection.

PubMed

Holt-Lunstad, Julianne

2018-01-04

Social relationships are adaptive and crucial for survival. This review presents existing evidence indicating that our social connections to others have powerful influences on health and longevity and that lacking social connection qualifies as a risk factor for premature mortality. A systems perspective is presented as a framework by which to move social connection into the realm of public health. Individuals, and health-relevant biological processes, exist within larger social contexts including the family, neighborhood and community, and society and culture. Applying the social ecological model, this review highlights the interrelationships of individuals within groups in terms of understanding both the causal mechanisms by which social connection influences physical health and the ways in which this influence can inform potential intervention strategies. A systems approach also helps identify gaps in our current understanding that may guide future research.

The emergence of a health insurance system in a developing country: the case of South Korea.

PubMed

Cho, S

1989-12-01

In an attempt to understand the social forces and the economic and political conditions under which new social policies emerge in developing countries, this study outlines factors affecting the introduction of the health insurance system in South Korea. The emergence of the South Korean health insurance system was influenced by changing labor needs of the industrial sector, increasing social expectations, external and international pressures, increasing medical costs, and class conflict. These pressures compelled the South Korean government to respond to demands for the introduction of new social welfare policies in the 1970s. In the case of South Korea, the new health insurance system resulted from the government's attempts to cope with political, economic, and social pressures rather than from an ideological commitment to the well-being of the population. The resulting insurance system was a way to maintain the social order and legitimacy of the regime, and a means to promote the health of groups important to defense or production.

Integrating social capital theory, social cognitive theory, and the technology acceptance model to explore a behavioral model of telehealth systems.

PubMed

Tsai, Chung-Hung

2014-05-07

Telehealth has become an increasingly applied solution to delivering health care to rural and underserved areas by remote health care professionals. This study integrated social capital theory, social cognitive theory, and the technology acceptance model (TAM) to develop a comprehensive behavioral model for analyzing the relationships among social capital factors (social capital theory), technological factors (TAM), and system self-efficacy (social cognitive theory) in telehealth. The proposed framework was validated with 365 respondents from Nantou County, located in Central Taiwan. Structural equation modeling (SEM) was used to assess the causal relationships that were hypothesized in the proposed model. The finding indicates that elderly residents generally reported positive perceptions toward the telehealth system. Generally, the findings show that social capital factors (social trust, institutional trust, and social participation) significantly positively affect the technological factors (perceived ease of use and perceived usefulness respectively), which influenced usage intention. This study also confirmed that system self-efficacy was the salient antecedent of perceived ease of use. In addition, regarding the samples, the proposed model fitted considerably well. The proposed integrative psychosocial-technological model may serve as a theoretical basis for future research and can also offer empirical foresight to practitioners and researchers in the health departments of governments, hospitals, and rural communities.

The oxytocin system in drug discovery for autism: Animal models and novel therapeutic strategies

PubMed Central

Modi, Meera E.; Young, Larry J.

2012-01-01

Animal models and behavioral paradigms are critical for elucidating the neural mechanism involved in complex behaviors, including social cognition. Both genotype and phenotype based models have implicated the neuropeptide oxytocin (OT) in the regulation of social behavior. Based on the findings in animal models, alteration of the OT system has been hypothesized to play a role in the social deficits associated with autism and other neuropsychiatric disorders. While the evidence linking the peptide to the etiology of the disorder is not yet conclusive, evidence from multiple animal models suggest modulation of the OT system may be a viable strategy for the pharmacological treatment of social deficits. In this review, we will discuss how animal models have been utilized to understand the role of OT in social cognition and how those findings can be applied to the conceptualization and treatment of the social impairments in ASD. Animal models with genetic alterations of the OT system, like the OT, OT receptor and CD38 knock-out mice, and those with phenotypic variation in social behavior, like BTBR inbred mice and prairie voles, coupled with behavioral paradigms with face and construct validity may prove to have predictive validity for identifying the most efficacious methods of stimulating the OT system to enhance social cognition in humans. The widespread use of strong animal models of social cognition has the potential yield pharmacological, interventions for the treatment social impairments psychiatric disorders.

Kramer, Sam L; Rodriguez, Benjamin F

2018-07-01

Evidence suggests that the behavior inhibition system (BIS) and fight-flight-freeze system play a role in the individual differences seen in social anxiety disorder; however, findings concerning the role of the behavior approach system (BAS) have been mixed. To date, the role of revised reinforcement sensitivity theory (RST) subsystems underlying social anxiety has been measured with scales designed for the original RST. This study examined how the BIS, BAS, and fight, flight, freeze components of the fight-flight-freeze system uniquely relate to social interaction anxiety and social observation anxiety using both a measure specifically designed for the revised RST and a commonly used original RST measure. Comparison of regression analyses with the Jackson-5 and the commonly used BIS/BAS Scales revealed important differences in the relationships between RST subsystems and social anxiety depending on how RST was assessed. Limitations and future directions for revised RST measurement are discussed.

Looking Through a Social Lens: Conceptualising Social Aspects of Knowledge Management for Global Health Practitioners

Limaye, Rupali J.; Sullivan, Tara M.; Dalessandro, Scott; Jenkins, Ann Hendrix

2017-01-01

Knowledge management plays a critical role in global health. Global health practitioners require knowledge in every aspect of their jobs, and in resource-scarce contexts, practitioners must be able to rely on a knowledge management system to access the latest research and practice to ensure the highest quality of care. However, we suggest that there is a gap in the way knowledge management is primarily utilized in global health, namely, the systematic incorporation of human and social factors. In this paper, we briefly outline the evolution of knowledge management and then propose a conceptualization of knowledge management that incorporates human and social factors for use within a global health context. Our conceptualization of social knowledge management recognizes the importance of social capital, social learning, social software and platforms, and social networks, all within the context of a larger social system and driven by social benefit. We then outline the limitations and discuss future directions of our conceptualization, and suggest how this new conceptualization is essential for any global health practitioner in the business of managing knowledge. Significance for public health Managing knowledge is essential for improving population health outcomes. Global health practitioners at all levels of the health system are bombarded with information related to best practices and guideline changes, among other relevant information to provide the best quality of care. Knowledge management, or the act of effectively using knowledge, has yet to capitalize on the power of social connections within the context of global health. While social elements have been incorporated into knowledge management activities, we suggest that systematically integrating key concepts that leverage social connections, such as social systems, social capital, social learning, and social software, will yield greater benefit with regard to health outcomes. As such, we outline a new conceptualization of knowledge management, focusing on the social aspects of the practice, and posit that such an approach can further the impact of global health interventions and is crucial for global health practitioners.

2017-07-21

Understanding the spreading mechanisms of social contagions in complex network systems has attracted much attention in the physics community. Here we propose a generalized threshold model to describe social contagions. Using extensive numerical simulations and theoretical analyses, we find that a hysteresis loop emerges in the system. Specifically, the steady state of the system is sensitive to the initial conditions of the dynamics of the system. In the steady state, the adoption size increases discontinuously with the transmission probability of information about social contagions, and trial size exhibits a non-monotonic pattern, i.e., it first increases discontinuously then decreases continuously. Finally we study social contagions on heterogeneous networks and find that network topology does not qualitatively affect our results.

Social Network Analysis as a Methodological Approach to Explore Health Systems: A Case Study Exploring Support among Senior Managers/Executives in a Hospital Network.

PubMed

De Brún, Aoife; McAuliffe, Eilish

2018-03-13

Health systems research recognizes the complexity of healthcare, and the interacting and interdependent nature of components of a health system. To better understand such systems, innovative methods are required to depict and analyze their structures. This paper describes social network analysis as a methodology to depict, diagnose, and evaluate health systems and networks therein. Social network analysis is a set of techniques to map, measure, and analyze social relationships between people, teams, and organizations. Through use of a case study exploring support relationships among senior managers in a newly established hospital group, this paper illustrates some of the commonly used network- and node-level metrics in social network analysis, and demonstrates the value of these maps and metrics to understand systems. Network analysis offers a valuable approach to health systems and services researchers as it offers a means to depict activity relevant to network questions of interest, to identify opinion leaders, influencers, clusters in the network, and those individuals serving as bridgers across clusters. The strengths and limitations inherent in the method are discussed, and the applications of social network analysis in health services research are explored.

Challenges and opportunities in social neuroscience

Cacioppo, John T.; Decety, Jean

2010-01-01

Social species are so characterized because they form organizations that extend beyond the individual. The goal of social neuroscience is to investigate the biological mechanisms that underlie these social structures, processes, and behavior and the influences between social and neural structures and processes. Such an endeavor is challenging because it necessitates the integration of multiple levels. Mapping across systems and levels (from genome to social groups and cultures) requires interdisciplinary expertise, comparative studies, innovative methods, and integrative conceptual analysis. Examples of how social neuroscience is contributing to our understanding of the functions of the brain and nervous system are described, and societal implications of social neuroscience are considered.

Oxytocin receptor gene polymorphism modulates the effects of social support on heart rate variability

2017-01-01

A large body of empirical research has demonstrated stress-buffering effects of social support. However, recent studies suggest that genetic variation of the oxytocin system (specifically, a common single nucleotide polymorphism, rs53576, of the oxytocin receptor gene) modulates the efficacy of social support. The timing and neurobiological basis of this genetic modulation were investigated using a standardized, laboratory-based psychological stress procedure (Trier Social Stress Test for Groups, TSST-G). To index potential stress buffering effects of social support mediated by the oxytocin system, heart rate variability (HRV) was obtained before and during the TSST-G from 40 healthy participants. Results indicate that social support is associated with higher HRV only in G allele carriers. Specifically, social support increased heart rate variability during direct social interaction and only in individuals with at least one copy of the G allele of rs53576. These findings support the idea that the stress-attenuating effects of social support are modulated by genetic variation of the oxytocin system. PMID:26903384

Design of a virtual reality based adaptive response technology for children with autism.

Children with autism spectrum disorder (ASD) demonstrate potent impairments in social communication skills including atypical viewing patterns during social interactions. Recently, several assistive technologies, particularly virtual reality (VR), have been investigated to address specific social deficits in this population. Some studies have coupled eye-gaze monitoring mechanisms to design intervention strategies. However, presently available systems are designed to primarily chain learning via aspects of one's performance only which affords restricted range of individualization. The presented work seeks to bridge this gap by developing a novel VR-based interactive system with Gaze-sensitive adaptive response technology that can seamlessly integrate VR-based tasks with eye-tracking techniques to intelligently facilitate engagement in tasks relevant to advancing social communication skills. Specifically, such a system is capable of objectively identifying and quantifying one's engagement level by measuring real-time viewing patterns, subtle changes in eye physiological responses, as well as performance metrics in order to adaptively respond in an individualized manner to foster improved social communication skills among the participants. The developed system was tested through a usability study with eight adolescents with ASD. The results indicate the potential of the system to promote improved social task performance along with socially-appropriate mechanisms during VR-based social conversation tasks.

The processing of social stimuli in early infancy: from faces to biological motion perception.

PubMed

Simion, Francesca; Di Giorgio, Elisa; Leo, Irene; Bardi, Lara

2011-01-01

There are several lines of evidence which suggests that, since birth, the human system detects social agents on the basis of at least two properties: the presence of a face and the way they move. This chapter reviews the infant research on the origin of brain specialization for social stimuli and on the role of innate mechanisms and perceptual experience in shaping the development of the social brain. Two lines of convergent evidence on face detection and biological motion detection will be presented to demonstrate the innate predispositions of the human system to detect social stimuli at birth. As for face detection, experiments will be presented to demonstrate that, by virtue of nonspecific attentional biases, a very coarse template of faces become active at birth. As for biological motion detection, studies will be presented to demonstrate that, since birth, the human system is able to detect social stimuli on the basis of their properties such as the presence of a semi-rigid motion named biological motion. Overall, the empirical evidence converges in supporting the notion that the human system begins life broadly tuned to detect social stimuli and that the progressive specialization will narrow the system for social stimuli as a function of experience.

Dynamics of Opinion Forming in Structurally Balanced Social Networks

PubMed Central

Altafini, Claudio

2012-01-01

A structurally balanced social network is a social community that splits into two antagonistic factions (typical example being a two-party political system). The process of opinion forming on such a community is most often highly predictable, with polarized opinions reflecting the bipartition of the network. The aim of this paper is to suggest a class of dynamical systems, called monotone systems, as natural models for the dynamics of opinion forming on structurally balanced social networks. The high predictability of the outcome of a decision process is explained in terms of the order-preserving character of the solutions of this class of dynamical systems. If we represent a social network as a signed graph in which individuals are the nodes and the signs of the edges represent friendly or hostile relationships, then the property of structural balance corresponds to the social community being splittable into two antagonistic factions, each containing only friends.

The absence of system of medical social monitoring of children being in difficult life situations is one of main causes of preventable losses of health and life of children and adolescents. The plan of activities of the working group No3 under the Coordination council under the President of the Russian Federation of the national strategy realization of actions in interest of children for 2012-2017 includes a point: "The development and implementation of standard model of medical social monitoring of children and adolescents in the subjects of the Russian Federation". The implementation of this task is assigned to the Department of social pediatrics of The research center of children health of Moscow and the Ministry of Health of the Republic of Tatarstan. The research methods included analysis and generalization of advanced experience of medical social monitoring of children population; expertise technique; modeling. The regional model of three-level system of medical social monitoring of children population is developed and implemented. The model includes level I (consulting rooms of medical social care of children polyclinics, feldsher obstetric stations, first-aid centers), level II--inter-municipal (departments of medical social monitoring in central district hospitals, medical institutions, clinical diagnostic centers) and level III--regional (the Republican center of medical social monitoring of children and adolescents). The immediate tasks necessary for effective functioning of system of medical social monitoring were determined. Within the framework of implementation of the pilot project the legal and normative legislative acts were developed to regulate functioning of regional model of three-level system of medical social care. The other documents necessary for effective functioning of this system were elaborated. The practical significance of this system is in the implementation of effective three-level model of medical social monitoring of children and adolescents supporting decrease of morbidity, mortality and "risk behaviors" suicidal included. The model is to prevent child neglect and homelessness and cruel treatment of children and adolescents.

Extensive studies have been performed on the role of monoaminergic neuronal systems in rodents exposed to social defeat stress as adults. In the present study, we investigated the role of monoaminergic neuronal systems in the impairment of social behaviors induced by social defeat stress exposure as juveniles. Juvenile, male C57BL/6J mice were exposed to social defeat stress for 10 consecutive days. From 1 day after the last stress exposure, desipramine, sertraline, and aripiprazole, were administered for 15 days. Social behaviors were assessed at 1 and 15 days after the last stress exposure. Monoamine turnover was determined in specific regions of the brain in the mice exposed to the stress. Stress exposure as juveniles induced the impairment of social behaviors in adolescent mice. In mice that showed the impairment of social behaviors, turnover of the serotonin and dopamine, but not noradrenaline was decreased in specific brain regions. Acute and repeated administration of desipramine, sertraline, and aripiprazole failed to attenuate the impairment of social behaviors, whereas repeated administration of a combination of sertraline and aripiprazole showed additive attenuating effects. These findings suggest that social defeat stress exposure as juveniles induces the treatment-resistant impairment of social behaviors in adolescents through dysfunction in the serotoninergic and dopaminergic neuronal systems. The combination of sertraline and aripiprazole may be used as a new treatment strategy for treatment-resistant stress-related psychiatric disorders in adolescents with adverse juvenile experiences.

Federalism and social justice: implications for social work.

Linhorst, Donald M

2002-07-01

Federalism is a system of government that divides power between two or more levels of government. 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.

Multiple time-scales and the developmental dynamics of social systems

PubMed Central

Flack, Jessica C.

2012-01-01

To build a theory of social complexity, we need to understand how aggregate social properties arise from individual interaction rules. Here, I review a body of work on the developmental dynamics of pigtailed macaque social organization and conflict management that provides insight into the mechanistic causes of multi-scale social systems. In this model system coarse-grained, statistical representations of collective dynamics are more predictive of the future state of the system than the constantly in-flux behavioural patterns at the individual level. The data suggest that individuals can perceive and use these representations for strategical decision-making. As an interaction history accumulates the coarse-grained representations consolidate. This constrains individual behaviour and provides the foundations for new levels of organization. The time-scales on which these representations change impact whether the consolidating higher-levels can be modified by individuals and collectively. The time-scales appear to be a function of the ‘coarseness’ of the representations and the character of the collective dynamics over which they are averages. The data suggest that an advantage of multiple timescales is that they allow social systems to balance tradeoffs between predictability and adaptability. I briefly discuss the implications of these findings for cognition, social niche construction and the evolution of new levels of organization in biological systems. PMID:22641819

Liu, Sandra S; Lu, Jui-Fen Rachel; Guo, Kristina L

2014-01-01

In this study, a conceptual framework was developed to show that social entrepreneurial practices can be effectively translated to meet the social needs in health care. We used a theory-in-use case study approach that encompasses postulation of a working taxonomy from literature scanning and a deliberation of the taxonomy through triangulation of multilevel data of a case study conducted in a Taiwan-based hospital system. Specifically, we demonstrated that a nonprofit organization can adopt business principles that emphasize both financial and social value. We tested our model and found comprehensive accountability across departments throughout the case hospital system, and this led to sustainable and continual growth of the organization. Through social entrepreneurial practices, we established that both financial value creation and fulfilling the social mission for the case hospital system can be achieved.

The brain endocannabinoid system plays a crucial role in emotional processes. We have previously identified an important role for endocannabinoids in social play behavior, a highly rewarding form of social interaction in adolescent rats. Here, we tested the hypothesis that endocannabinoid modulation of social play behavior occurs in brain regions implicated in emotion and motivation. Social play increased levels of the endocannabinoid anandamide in the amygdala and nucleus accumbens (NAc), but not in prefrontal cortex or hippocampus of 4- to 5-week-old male Wistar rats. Furthermore, social play increased phosphorylation of CB1 cannabinoid receptors in the amygdala. Systemic administration of the anandamide hydrolysis inhibitor URB597 increased social play behavior, and augmented the associated elevation in anandamide levels in the amygdala, but not the NAc. Infusion of URB597 into the basolateral amygdala (BLA) increased social play behavior, and blockade of BLA CB1 cannabinoid receptors with the antagonist/inverse agonist SR141716A prevented the play-enhancing effects of systemic administration of URB597. Infusion of URB597 into the NAc also increased social play, but blockade of NAc CB1 cannabinoid receptors did not antagonize the play-enhancing effects of systemic URB597 treatment. Last, SR141716A did not affect social play after infusion into the core and shell subregions of the NAc, while it reduced social play when infused into the BLA. These data show that increased anandamide signaling in the amygdala and NAc augments social play, and identify the BLA as a prominent site of action for endocannabinoids to modulate the rewarding properties of social interactions in adolescent rats.

A Markov chain model for image ranking system in social networks

In today world, different kinds of networks such as social, technological, business and etc. exist. All of the networks are similar in terms of distributions, continuously growing and expanding in large scale. Among them, many social networks such as Facebook, Twitter, Flickr and many others provides a powerful abstraction of the structure and dynamics of diverse kinds of inter personal connection and interaction. Generally, the social network contents are created and consumed by the influences of all different social navigation paths that lead to the contents. Therefore, identifying important and user relevant refined structures such as visual information or communities become major factors in modern decision making world. Moreover, the traditional method of information ranking systems cannot be successful due to their lack of taking into account the properties of navigation paths driven by social connections. In this paper, we propose a novel image ranking system in social networks by using the social data relational graphs from social media platform jointly with visual data to improve the relevance between returned images and user intentions (i.e., social relevance). Specifically, we propose a Markov chain based Social-Visual Ranking algorithm by taking social relevance into account. By using some extensive experiments, we demonstrated the significant and effectiveness of the proposed social-visual ranking method.

Social ties are crucial for humans. Disruption of ties through social exclusion has a marked effect on our thoughts and feelings; however, such effects can be tempered by broader social network resources. Here, we use fMRI data acquired from 80 male adolescents to investigate how social exclusion modulates functional connectivity within and across brain networks involved in social pain and understanding the mental states of others (i.e., mentalizing). Furthermore, using objectively logged friendship network data, we examine how individual variability in brain reactivity to social exclusion relates to the density of participants’ friendship networks, an important aspect of social network structure. We find increased connectivity within a set of regions previously identified as a mentalizing system during exclusion relative to inclusion. These results are consistent across the regions of interest as well as a whole-brain analysis. Next, examining how social network characteristics are associated with task-based connectivity dynamics, we find that participants who showed greater changes in connectivity within the mentalizing system when socially excluded by peers had less dense friendship networks. This work provides insight to understand how distributed brain systems respond to social and emotional challenges and how such brain dynamics might vary based on broader social network characteristics.

Neural mechanisms tracking popularity in real-world social networks.

Zerubavel, Noam; Bearman, Peter S; Weber, Jochen; Ochsner, Kevin N

2015-12-08

Differences in popularity are a key aspect of status in virtually all human groups and shape social interactions within them. Little is known, however, about how we track and neurally represent others' popularity. We addressed this question in two real-world social networks using sociometric methods to quantify popularity. Each group member (perceiver) viewed faces of every other group member (target) while whole-brain functional MRI data were collected. Independent functional localizer tasks were used to identify brain systems supporting affective valuation (ventromedial prefrontal cortex, ventral striatum, amygdala) and social cognition (dorsomedial prefrontal cortex, precuneus, temporoparietal junction), respectively. During the face-viewing task, activity in both types of neural systems tracked targets' sociometric popularity, even when controlling for potential confounds. The target popularity-social cognition system relationship was mediated by valuation system activity, suggesting that observing popular individuals elicits value signals that facilitate understanding their mental states. The target popularity-valuation system relationship was strongest for popular perceivers, suggesting enhanced sensitivity to differences among other group members' popularity. Popular group members also demonstrated greater interpersonal sensitivity by more accurately predicting how their own personalities were perceived by other individuals in the social network. These data offer insights into the mechanisms by which status guides social behavior.

Social conditions are the first environment that modulate external factors which impact on health. In turn gender is a decisive factor in these social determinants of health. This paper analyzes gender bias in the health system as a relevant part in social determinants. We can distinguish three types of bias: cognitive, social, and institutional. In the institutional biases, we analyze the risks of gender and costs originated from the coordination between the health system and the system of social protection. Finally, we suggest a series of measures to minimize these biases and risks. Copyright © 2015 Elsevier España, S.L.U. All rights reserved.

Resilience in social insect infrastructure systems.

PubMed

Middleton, Eliza J T; Latty, Tanya

2016-03-01

Both human and insect societies depend on complex and highly coordinated infrastructure systems, such as communication networks, supply chains and transportation networks. Like human-designed infrastructure systems, those of social insects are regularly subject to disruptions such as natural disasters, blockages or breaks in the transportation network, fluctuations in supply and/or demand, outbreaks of disease and loss of individuals. Unlike human-designed systems, there is no deliberate planning or centralized control system; rather, individual insects make simple decisions based on local information. How do these highly decentralized, leaderless systems deal with disruption? What factors make a social insect system resilient, and which factors lead to its collapse? In this review, we bring together literature on resilience in three key social insect infrastructure systems: transportation networks, supply chains and communication networks. We describe how systems differentially invest in three pathways to resilience: resistance, redirection or reconstruction. We suggest that investment in particular resistance pathways is related to the severity and frequency of disturbance. In the final section, we lay out a prospectus for future research. Human infrastructure networks are rapidly becoming decentralized and interconnected; indeed, more like social insect infrastructures. Human infrastructure management might therefore learn from social insect researchers, who can in turn make use of the mature analytical and simulation tools developed for the study of human infrastructure resilience. © 2016 The Author(s).

The symbolic power of money: reminders of money alter social distress and physical pain.

PubMed

Zhou, Xinyue; Vohs, Kathleen D; Baumeister, Roy F

2009-06-01

People often get what they want from the social system, and that process is aided by social popularity or by having money. Money can thus possibly substitute for social acceptance in conferring the ability to obtain benefits from the social system. Moreover, past work has suggested that responses to physical pain and social distress share common underlying mechanisms. Six studies tested relationships among reminders of money, social exclusion, and physical pain. Interpersonal rejection and physical pain caused desire for money to increase. Handling money (compared with handling paper) reduced distress over social exclusion and diminished the physical pain of immersion in hot water. Being reminded of having spent money, however, intensified both social distress and physical pain.

Comparison of social and physical free energies on a toy model.

PubMed

Kasac, Josip; Stefancic, Hrvoje; Stepanic, Josip

2004-01-01

Social free energy has been recently introduced as a measure of social action obtainable in a given social system, without changes in its structure. The authors of this paper argue that social free energy surpasses the gap between the verbally formulated value sets of social systems and the quantitatively based predictions. This point is further developed by analyzing the relation between the social and the physical free energy. Generically, this is done for a particular type of social dynamics. The extracted type of social dynamics is one of many realistic types of the differing proportion of social and economic elements. Numerically, this has been done for a toy model of interacting agents. The values of the social and physical free energies are, within the numerical accuracy, equivalent in the class of nontrivial, quasistationary model states.

Integrating automatic and controlled processes into neurocognitive models of social cognition.

PubMed

Satpute, Ajay B; Lieberman, Matthew D

2006-03-24

Interest in the neural systems underlying social perception has expanded tremendously over the past few decades. However, gaps between behavioral literatures in social perception and neuroscience are still abundant. In this article, we apply the concept of dual-process models to neural systems in an effort to bridge the gap between many of these behavioral studies and neural systems underlying social perception. We describe and provide support for a neural division between reflexive and reflective systems. Reflexive systems correspond to automatic processes and include the amygdala, basal ganglia, ventromedial prefrontal cortex, dorsal anterior cingulate cortex, and lateral temporal cortex. Reflective systems correspond to controlled processes and include lateral prefrontal cortex, posterior parietal cortex, medial prefrontal cortex, rostral anterior cingulate cortex, and the hippocampus and surrounding medial temporal lobe region. This framework is considered to be a working model rather than a finished product. Finally, the utility of this model and its application to other social cognitive domains such as Theory of Mind are discussed.

The proper contributions of social workers in health practice.

PubMed

Huntington, J

1986-01-01

Current and potential future contributions of social workers to health practice are considered at the three levels of direct service to patients, influence on the processes and procedures of the health setting and influence on its future planning and service development. The capacity of U.S.A. and U.K. social work to contribute at these levels is compared in the light of their contrasting relationships to the health system. U.S.A. social work in health care is practised as employees of the health setting or as private practitioners and contains the majority of U.S.A. social workers. It remains a specialism that sustains a major body of published work, commitment to knowledge-building, standard setting and performance review, and a psycho-social orientation shared by a growing number of medical and nursing professionals. Its approach to the health system is that of the pursuit of professional credibility in the secondary setting by adopting the professional-technical practice model of the clinician. U.K. social work since the early 1970s has been committed to generic education and practice and to the development of its own primary setting in social services departments which now employ almost all U.K. social workers. Area team social work in these departments, typified by statutory work with the most deprived sections of the population, has become the dominant culture of British social work, with implications for the occupational identity and career prospects of those social workers who are outposted or attached to health settings but no longer employed by them. British social work and its management now approach the health system from a position of organizational independence which should strengthen their capacity to influence the health system. The cultural differences between social work and medicine, however, are experienced more keenly than ever as many social workers adopt a socio-political practice model that is at odds with the professional-technical model of the clinician. Provision of social work services to the health system has become a questionable priority and raises the issue of whether much of what is now termed "health care' could more appropriately be termed "social care' and provided in a primary social work setting to which medicine and nursing would make their "proper contributions'.

Social phobia: etiology, neurobiology, and treatment.

PubMed

Coupland, N J

2001-01-01

Social phobia is a common and often disabling condition, with an etiology that is not established. There is evidence at several levels for an interplay of biological and psychological processes in social phobia. Genetic studies show that both genetic and environmental factors are important, with evidence pointing to associations with 2 genetic conditions, autism and fragile X syndrome. Behavioral inhibition has emerged as an important precursor to social phobia and possibly to other anxiety disorders. Epidemiologic and clinical studies have suggested that factors within the family environment, such as overprotection, overcontrol, modeling of anxiety, criticism, and in some cases abuse, can play a role in the development of social phobia. During childhood, complex interactions between brain system disturbances that mediate responses to negative social cues and factors in the social setting may lead to the development of a distorted set of internal "blueprints" for social behavior. The impact of severe social anxiety on brain systems that mediate behavioral change may prevent patients from learning better "blueprints." These can be taught through cognitive-behavioral therapies. The effective control of social anxiety with medications enables patients to recover; whether recovery can last after discontinuation of medications may depend on whether a new "blueprint" has been developed and whether stable changes in affected brain systems have occurred. Neuroimaging techniques are at the early stage of identifying abnormalities at the neurotransmitter and systems levels.

Toward social system theory: implications for older people with developmental disabilities and service delivery.

PubMed

Dossa, P A

1990-01-01

The literature refers to older people with developmental disabilities as the "new service population." How and why this population emerged as a special category is discussed conceptually with reference to social systems theory. A brief review of social systems theory and some basic systemic tenets are presented. Systemic tenets are employed in examining the historical development of social gerontology and present trends in the service-delivery system. I show that the systemic variable of the economic model of human development has significantly impacted on the making of older people with developmental disabilities a dependent population. In the conclusion the systems perspective is explored in relation to recognizing the liminal, in-between parts between components. It is argued that such a perception minimizes the dichotomy between older people with developmental disabilities and the non-disabled population, paving the way for a genuine encounter.

Integrating Social Services and Home-Based Primary Care for High-Risk Patients.

Feinglass, Joe; Norman, Greg; Golden, Robyn L; Muramatsu, Naoko; Gelder, Michael; Cornwell, Thomas

2018-04-01

There is a consensus that our current hospital-intensive approach to care is deeply flawed. This review article describes the research evidence for developing a better system of care for high-cost, high-risk patients. It reviews the evidence that home-centered care and integration of health care with social services are the cornerstones of a more humane and efficient system. The article describes the strengths and weaknesses of research evaluating the effects of social services in addressing social determinants of health, and how social support is critical to successful acute care transition programs. It reviews the history of incorporating social services into care management, and the prospects that recent payment reforms and regulatory initiatives can succeed in stimulating the financial integration of social services into new care coordination initiatives. The article reviews the literature on home-based primary care for the chronically ill and disabled, and suggests that it is the emergence of this care modality that holds the greatest promise for delivery system reform. In the hope of stimulating further discussion and debate, the authors summarize existing viewpoints on how a home-centered system, which integrates social and medical services, might emerge in the next few years.

Social Justice for Crossover Youth: The Intersection of the Child Welfare and Juvenile Justice Systems.

PubMed

Kolivoski, Karen M; Goodkind, Sara; Shook, Jeffrey J

2017-10-01

Social workers are critical to promoting racial and social justice. "Crossover youth," a term used to describe youths who have contact with both the child welfare and juvenile justice systems, are an especially vulnerable but often overlooked population with whom social workers engage. A disproportionate number of crossover youth are African American. Empirical research on crossover youth is growing, but such scholarship rarely engages with a human rights and social justice perspective. African American children and youths have a distinct place within the history and current context of the child welfare and juvenile justice systems. These systems have historically excluded them or treated them differently; now, African American youths are overrepresented in each of them, and evidence suggests they are more likely to cross over. The purpose of this article is to describe the historical and current context of crossover youth, with a particular focus on African American youths, to provide the foundation for a discussion of what social workers can do to promote racial and social justice for crossover youth, including specific implications for practice and policy, as well as broader implications for human and civil rights. © 2017 National Association of Social Workers.

Corticospinal excitability during the observation of social behavior.

PubMed

Bucchioni, Giulia; Cavallo, Andrea; Ippolito, Davide; Marton, Gianluca; Castiello, Umberto

2013-03-01

Evidence suggests that the observation of an action induces in the observers an enhancement of motor evoked potentials (MEPs) recorded by the observer's muscles corresponding to those involved in the observed action. Although this is a well-studied phenomenon, it remains still unclear how the viewer's motor facilitation is influenced by the social content characterizing the observed scene. In the present study we investigated the facilitation of the corticospinal system during the observation of either an action that does not imply a social interaction (i.e., an actor throwing a ball against a wall), or an action which implies a social interaction (i.e., an actor passing a ball to a partner). Results indicate that MEPs amplitude is enhanced during the observation of a social rather than an individual action. We contend that the increase in MEPs activation might reflect an enhancement of the simulative activity stemming from the mirror system during the observation of social interactions. Altogether these findings show that the human corticospinal system is sensitive to social interactions and may support the role of the mirror neurons system in social cognition.

Social-ecological outcomes in recreational fisheries: the interaction of lakeshore development and stocking.

PubMed

Ziegler, Jacob P; Golebie, Elizabeth J; Jones, Stuart E; Weidel, Brian C; Solomon, Christopher T

2017-01-01

Many ecosystems continue to experience rapid transformations due to processes like land use change and resource extraction. A systems approach to maintaining natural resources focuses on how interactions and feedbacks among components of complex social-ecological systems generate social and ecological outcomes. In recreational fisheries, residential shoreline development and fish stocking are two widespread human behaviors that influence fisheries, yet emergent social-ecological outcomes from these potentially interacting behaviors remain under explored. We applied a social-ecological systems framework using a simulation model and empirical data to determine whether lakeshore development is likely to promote stocking through its adverse effects on coarse woody habitat and thereby also on survival of juvenile and adult fish. We demonstrate that high lakeshore development is likely to generate dependency of the ecosystem on the social system, in the form of stocking. Further, lakeshore development can interact with social-ecological processes to create deficits for state-level governments, which threatens the ability to fund further ecosystem subsidies. Our results highlight the value of a social-ecological framework for maintaining ecosystem services like recreational fisheries. © 2016 by the Ecological Society of America.

Sex differences in the oxytocin (OT) system in the brain may explain why OT often regulates social behaviors in sex-specific ways. However, a link between sex differences in the OT system and sex-specific regulation of social behavior has not been tested. Here, we determined whether sex differences in the OT receptor (OTR) or in OT release in the posterior bed nucleus of the stria terminalis (pBNST) mediates sex-specific regulation of social recognition in rats. We recently showed that, compared to female rats, male rats have a three-fold higher OTR binding density in the pBNST, a sexually dimorphic area implicated in the regulation of social behaviors. We now demonstrate that OTR antagonist (5 ng/0.5 μl/side) administration into the pBNST impairs social recognition in both sexes, while OT (100 pg/0.5 μl/side) administration into the pBNST prolongs the duration of social recognition in males only. These effects seem specific to social recognition, as neither treatment altered total social investigation time in either sex. Moreover, baseline OT release in the pBNST, as measured with in vivo microdialysis, did not differ between the sexes. However, males showed higher OT release in the pBNST during social recognition compared to females. These findings suggest a sex-specific role of the OT system in the pBNST in the regulation of social recognition. Copyright © 2015 Elsevier Ltd. All rights reserved.

Gender and cultural differences in the association between family roles, social stratification, and alcohol use: a European cross-cultural analysis.

First, this paper investigates (i) gender differences in associations of social stratification, family roles, and heavy drinking, and (ii) country differences in these associations. Second, it seeks to explain country differences in the associations of social stratification and family roles with alcohol consumption by societal level variables. Survey data of 25 to 49-years-old from eight European countries were used. Logistic regressions were used to analyse gender differences in the association between family roles (marriage, having children), social stratification (education, employment), and heavy drinking (>20 g/day for women; 30 g/day for men). Gender differences were tested by means of interactions between gender and social stratification/family roles. Structural measures of work desirability, social welfare, and gender equity were used to explain differences in associations across countries. The associations between social stratification, family roles, and heavy drinking varied across gender and countries. A country's social welfare system was associated with heavy drinking only among women. Women in countries with a strong social welfare system, such as Nordic countries, tended to drink more heavily if employed, having lower formal education, and a non-traditional family role. In countries with weak social welfare systems or work desirability, heavy drinking was associated with high education, while effects of family roles and employment were small. It appeared that the social welfare system and gender equity of a country determines to a large extent how education, employment, and family roles are associated with heavy drinking.

Experience of the drawbacks of a globalised and industrialised food system has generated interest in localised food systems. Local food networks are regarded as more sustainable food provision systems since they are assumed to have high levels of social embeddedness and relations of regard. This paper explores the social relations between food…

Understanding and applying principles of social cognition and ...

EPA Pesticide Factsheets

Environmental governance systems are under greater pressure to adapt and to cope with increased social and ecological uncertainty from stressors like climate change. We review principles of social cognition and decision making that shape and constrain how environmental governance systems adapt. We focus primarily on the interplay between key decision makers in society and legal systems. We argue that adaptive governance must overcome three cooperative dilemmas to facilitate adaptation: (1) encouraging collaborative problem solving, (2) garnering social acceptance and commitment, and (3) cultivating a culture of trust and tolerance for change and uncertainty. However, to do so governance systems must cope with biases in people’s decision making that cloud their judgment and create conflict. These systems must also satisfy people’s fundamental needs for self-determination, fairness, and security, ensuring that changes to environmental governance are perceived as legitimate, trustworthy, and acceptable. We discuss the implications of these principles for common governance solutions (e.g., public participation, enforcement) and conclude with methodological recommendations. We outline how scholars can investigate the social cognitive principles involved in cases of adaptive governance. Social-ecological stressors place significant pressure on major societal systems, triggering adaptive reforms in human governance and environmental law. Though potentially benefici

In non-human primates, opioid-receptor blockade increases social grooming, and the endogenous opioid system has therefore been hypothesized to support maintenance of long-term relationships in humans as well. Here we tested whether social touch modulates opioidergic activation in humans using in vivo positron emission tomography (PET). Eighteen male participants underwent two PET scans with [11C]carfentanil, a ligand specific to μ-opioid receptors (MOR). During the social touch scan, the participants lay in the scanner while their partners caressed their bodies in a non-sexual fashion. In the baseline scan, participants lay alone in the scanner. Social touch triggered pleasurable sensations and increased MOR availability in the thalamus, striatum, and frontal, cingulate, and insular cortices. Modulation of activity of the opioid system by social touching might provide a neurochemical mechanism reinforcing social bonds between humans. Copyright © 2016 Elsevier Inc. All rights reserved.

Dopamine and dopamine receptor D1 associated with decreased social interaction.

Deficits in social interaction are hallmarks of neurological and psychiatric disorders. However, its underlying mechanism is still unclear. Here, we show that the loss of dendritic cell factor 1 (Dcf1) in the nervous system of mice induces social interaction deficiency, autism-like behaviour, and influences social interaction via the dopamine system. Dopamine receptor D1 agonist rescues this social cognition phenotype, and improves short-term plasticity. Together, this study presents a new genetic mechanism that affects social interaction and may provide a new way to improve positive social interaction and treat autism spectrum disorders.

Big cats as a model system for the study of the evolution of intelligence.

PubMed

Borrego, Natalia

2017-08-01

Currently, carnivores, and felids in particular, are vastly underrepresented in cognitive literature, despite being an ideal model system for tests of social and ecological intelligence hypotheses. Within Felidae, big cats (Panthera) are uniquely suited to studies investigating the evolutionary links between social, ecological, and cognitive complexity. Intelligence likely did not evolve in a unitary way but instead evolved as the result of mutually reinforcing feedback loops within the physical and social environments. The domain-specific social intelligence hypothesis proposes that social complexity drives only the evolution of cognitive abilities adapted only to social domains. The domain-general hypothesis proposes that the unique demands of social life serve as a bootstrap for the evolution of superior general cognition. Big cats are one of the few systems in which we can directly address conflicting predictions of the domain-general and domain-specific hypothesis by comparing cognition among closely related species that face roughly equivalent ecological complexity but vary considerably in social complexity.

[Neural and cognitive correlates of social cognition: findings on neuropsychological and neuroimaging studies].

PubMed

Kobayakawa, Mutsutaka; Kawamura, Mitsuru

2011-12-01

Social cognition includes various components of information processing related to communication with other individuals. In this review, we have discussed 3 components of social cognitive function: face recognition, empathy, and decision making. Our social behavior involves recognition based on facial features and also involves empathizing with others; while making decisions, it is important to consider the social consequences of the course of action followed. Face recognition is divided into 2 routes for information processing: a route responsible for overt recognition of the face's identity and a route for emotional and orienting responses based on the face's personal affective significance. Two systems are possibly involved in empathy: a basic emotional contagion "mirroring" system and a more advanced "theory of mind" system that considers the cognitive perspective. Decision making is mediated by a widespread system that includes several cortical and subcortical components. Numerous lesion and neuroimaging studies have contributed to clarifying the neural correlates of social cognitive function, and greater information can be obtained on social cognitive function by combining these 2 approaches.

Selling Innovations Like Soap: The Interactive Systems Framework and Social Marketing.

McAlindon, Kathryn

2017-09-01

Despite the popularity and noted utility of Wandersman and colleagues' (2008) Interactive Systems Framework, the literature currently provides a primary focus on delivery organizations' and supportive stakeholders' capacities and strategies to implement innovations, presenting a critical gap in understanding. Unfortunately, reflective of a larger void in community dissemination and implementation efforts, there is a more limited focus on the dissemination of innovations. This paper presents the social marketing literature as a supplement to the Prevention Synthesis and Translation System (PSTS), the system responsible for dissemination. The study and practice of innovation synthesis and translation is examined in the literature; and based on the conclusions drawn, social marketing theory is used to provide a systematic approach to improving dissemination within the Interactive Systems Framework. Specifically, three gaps related to the PSTS are identified in the literature that align with and can be filled using social marketing. Social marketing is defined and presented as a supplement by providing theory and practices, within a systems context, for effectively communicating and influencing change. By blending social marketing with the Interactive Systems Framework, the aim is to improve the understanding of strategic communication and its role in the effective dissemination, and subsequent implementation, of innovations. © Society for Community Research and Action 2017.

The foundation of the Actionable Capability for Social and Economic Systems (ACSES) project is a useful regional-scale social-simulation system. This report is organized into five chapters that describe insights that were gained concerning the five key feasibility questions pertaining to such a system: (1) Should such a simulation system exist, would the current state of data sets or collectible data sets be adequate to support such a system? (2) By comparing different agent-based simulation systems, is it feasible to compare simulation systems and select one appropriate for a given application with agents behaving according to modern social theory rather thanmore » ad hoc rule sets? (3) Provided that a selected simulation system for a region of interest could be constructed, can the simulation system be updated with new and changing conditions so that the universe of potential outcomes are constrained by events on the ground as they evolve? (4) As these results are constrained by evolving events on the ground, is it feasible to still generate surprise and emerging behavior to suggest outcomes from novel courses of action? (5) As these systems may for the first time require large numbers (hundreds of millions) of agents operating with complexities demanded of modern social theories, can results still be generated within actionable decision cycles?« less

2002-01-01

The aim of this study is to present the results of the reforms in the health sector that have taken place in Colombia since 1990. These reforms replaced the previous national health system and the so-called Bismarkian social security system. The new system has three basic characteristics: a) the public subsidies are decentralized in the municipalities and territorial departments; b) the public hospitals have been converted into state social enterprises, which has led them towards a management model, and c) the health and social security system monopoly has been abolished and a system of health subsidies has been created for the poorest citizens. This article systematically collects secondary information extracted from the most important studies evaluating the health sector reforms in Colombia. The present author participated in some of these studies. The reforms have increased financial resources, which, has led to an increase in public system staff and their salaries. The availability of hospitals' budgetary resources has increased and the social security system has become wider, including 20% of the poorest population who have benefited from subsidies on demand. Ease of access and equity in the health system have significantly improved. However, indicators of public health have fallen and health professionals are critical of a system based on mediation, which increases transaction costs.

Arm yourself for the coming battle over Social Security.

Pozen, Robert C

2002-11-01

The U.S. Social Security system is in deep trouble--and that's not just bad news for your friends and family. It's also bad news for your company. Unless the Social Security system is changed, by 2017 the cash flowing out of it will exceed the cash coming in, and by 2041 the system will be utterly insolvent. But the trouble will start sooner than that: In the next decade, the very prospect of the rising deficit will mean serious pressure on recent tax cuts, higher long-term interest rates, increased pension-funding costs, and other punishing conditions for U.S. businesses. Clearly, there's a lot at stake for companies, which is why executives need to participate in the growing debate about Social Security reform, says Robert Pozen, a visiting professor at Harvard Law School who served on the President's Commission to Strengthen Social Security. In this article, he urges business leaders to take a stance on how the system should be reformed, suggesting they work with interest groups to make their voices heard. After taking a comprehensive look at the debates surrounding Social Security reform, Pozen outlines the three main alternatives executives might choose to support: increasing contributions to Social Security, decreasing the growth of benefits for more-affluent workers, and increasing investment returns on Social Security assets. What's needed to fix the current system, he contends, is a careful balance of all three.

The emergency department (ED) can be a critical intervention point for many patients with multifaceted needs. Social workers have long been part of interdisciplinary ED teams. This study aimed to contribute to the limited understanding of social worker-patient interactions and factors influencing social work services in this setting. This paper reports a qualitative content analysis of social work medical record notes (N = 1509) of services provided to trauma patients in an urban, public, level 1 trauma center and an in-depth analysis of semi-structured interviews with ED social workers (N = 10). Eight major social work roles were identified: investigator, gatekeeper, resource broker, care coordinator, problem solver, crisis manager, advocate, discharge planner. Analyses revealed a complex interplay between ED social work services and multi-layered contexts. Using a social-ecological framework, we identified the interactions between micro or individual level factors, mezzo or local system level factors and macro environmental and systemic factors that play a role in ED interactions and patient services. Macro-level contextual influences were socio-structural forces including socioeconomic barriers to health, social hierarchies that reflected power differentials between providers and patients, and distrust or bias. Mezzo-level forces were limited resources, lack of healthcare system coordination, a challenging hierarchy within the medical model and the pressure to discharge patients quickly. Micro-level factors included characteristics of patients and social workers, complexity of patient stressors, empathic strain, lack of closure and compassion. All of these forces were at play in patient-social worker interactions and impacted service provision. Social workers were at times able to successfully navigate these forces, yet at other times these challenges were insurmountable. A conceptual model of ED social work and the influences on the patient-social worker interactions was developed to assist in guiding innovative research and practice models to improve services and outcomes in the complex, fast-paced ED.

The brain endocannabinoid system plays a crucial role in emotional processes. We have previously identified an important role for endocannabinoids in social play behavior, a highly rewarding form of social interaction in adolescent rats. Here, we tested the hypothesis that endocannabinoid modulation of social play behavior occurs in brain regions implicated in emotion and motivation. Social play increased levels of the endocannabinoid anandamide in the amygdala and nucleus accumbens (NAc), but not in prefrontal cortex or hippocampus of 4–5 week old male Wistar rats. Furthermore, social play increased phosphorylation of CB1 cannabinoid receptors in the amygdala. Systemic administration of the anandamide hydrolysis inhibitor URB597 increased social play behavior, and augmented the associated elevation in anandamide levels in the amygdala, but not the NAc. Infusion of URB597 into the basolateral amygdala (BLA) increased social play behavior, and blockade of BLA CB1 cannabinoid receptors with the antagonist/inverse agonist SR141716A prevented the play-enhancing effects of systemic administration of URB597. Infusion of URB597 into the NAc also increased social play, but blockade of NAc CB1 cannabinoid receptors did not antagonize the play-enhancing effects of systemic URB597 treatment. Last, SR141716A did not affect social play after infusion into the core and shell subregions of the NAc, while it reduced social play when infused into the BLA. These data show that increased anandamide signalling in the amygdala and NAc augments social play, and identify the BLA as a prominent site of action for endocannabinoids to modulate the rewarding properties of social interactions in adolescent rats.

Augmenting Trust Establishment in Dynamic Systems with Social Networks

Lagesse, Brent J; Kumar, Mohan; Venkatesh, Svetha

Social networking has recently flourished in popularity through the use of social websites. Pervasive computing resources have allowed people stay well-connected to each other through access to social networking resources. We take the position that utilizing information produced by relationships within social networks can assist in the establishment of trust for other pervasive computing applications. Furthermore, we describe how such a system can augment a sensor infrastructure used for event observation with information from mobile sensors (ie, mobile phones with cameras) controlled by potentially untrusted third parties. Pervasive computing systems are invisible systems, oriented around the user. As a result,more » many future pervasive systems are likely to include a social aspect to the system. The social communities that are developed in these systems can augment existing trust mechanisms with information about pre-trusted entities or entities to initially consider when beginning to establish trust. An example of such a system is the Collaborative Virtual Observation (CoVO) system fuses sensor information from disaparate sources in soft real-time to recreate a scene that provides observation of an event that has recently transpired. To accomplish this, CoVO must efficently access services whilst protecting the data from corruption from unknown remote nodes. CoVO combines dynamic service composition with virtual observation to utilize existing infrastructure with third party services available in the environment. Since these services are not under the control of the system, they may be unreliable or malicious. When an event of interest occurs, the given infrastructure (bus cameras, etc.) may not sufficiently cover the necessary information (be it in space, time, or sensor type). To enhance observation of the event, infrastructure is augmented with information from sensors in the environment that the infrastructure does not control. These sensors may be unreliable, uncooperative, or even malicious. Additionally, to execute queries in soft real-time, processing must be distributed to available systems in the environment. We propose to use information from social networks to satisfy these requirements. In this paper, we present our position that knowledge gained from social activities can be used to augment trust mechanisms in pervasive computing. The system uses social behavior of nodes to predict a subset that it wants to query for information. In this context, social behavior such as transit patterns and schedules (which can be used to determine if a queried node is likely to be reliable) or known relationships, such as a phone's address book, that can be used to determine networks of nodes that may also be able to assist in retrieving information. Neither implicit nor explicit relationships necessarily imply that the user trusts an entity, but rather will provide a starting place for establishing trust. The proposed framework utilizes social network information to assist in trust establishment when third-party sensors are used for sensing events.« less

Endogenous fertility, altruistic behavior across generations, and social security systems.

PubMed

Prinz, A

1990-01-01

This study examines the possible link between the existence of a pay-as-you-go social security program and individual procreative behavior. When a public old-age income support system takes the place of within-family support, the theoretical literature preducts that fertility rates will decline since children are no longer perceived as important to the old age security of the parents. The author takes up this theoretical problem and examines it through three different but related issues: optimal capital accumulation, optimal population growth and the role of social institutions affecting efficient intergenerational allocations. Econometric analysis employing a steady state growth model is used. Altruism between generations is studied for effect on the standard model. The model shows that for social optimum the per capita pension is related to the growth rate of the population, therefore, for society as a whole, children are investment goods. However, given the existence of a social security system, it is in each household's best interest to have no children at all. Only a government transfer, a child allowance to parents, changes the model and fertility rates. When modified to account for "caring" the model demonstrates that altruistic behavior between generations is not symmetrical. The study concludes that a pay-as-you-go funded social security system should be supplemented by a system of child allowances or replaced by a fully funded social security system.

Host social organization and mating system shape parasite transmission opportunities in three European bat species.

van Schaik, J; Kerth, G

For non-mobile parasites living on social hosts, infection dynamics are strongly influenced by host life history and social system. We explore the impact of host social systems on parasite population dynamics by comparing the infection intensity and transmission opportunities of three mite species of the genus Spinturnix across their three European bat hosts (Myotis daubentonii, Myotis myotis, Myotis nattereri) during the bats' autumn mating season. Mites mainly reproduce in host maternity colonies in summer, but as these colonies are closed, opportunities for inter-colony transmission are limited to host interactions during the autumn mating season. The three investigated hosts differ considerably in their social system, most notably in maternity colony size, mating system, and degree of male summer aggregation. We observed marked differences in parasite infection during the autumn mating period between the species, closely mirroring the predictions made based on the social systems of the hosts. Increased host aggregation sizes in summer yielded higher overall parasite prevalence and intensity, both in male and female hosts. Moreover, parasite levels in male hosts differentially increased throughout the autumn mating season in concordance with the degree of contact with female hosts afforded by the different mating systems of the hosts. Critically, the observed host-specific differences have important consequences for parasite population structure and will thus affect the coevolutionary dynamics between the interacting species. Therefore, in order to accurately characterize host-parasite dynamics in hosts with complex social systems, a holistic approach that investigates parasite infection and transmission across all periods is warranted.

How attention gates social interactions.

PubMed

Capozzi, Francesca; Ristic, Jelena

Social interactions are at the core of social life. However, humans selectively choose their exchange partners and do not engage in all available opportunities for social encounters. In this review, we argue that attentional systems play an important role in guiding the selection of social interactions. Supported by both classic and emerging literature, we identify and characterize the three core processes-perception, interpretation, and evaluation-that interact with attentional systems to modulate selective responses to social environments. Perceptual processes facilitate attentional prioritization of social cues. Interpretative processes link attention with understanding of cues' social meanings and agents' mental states. Evaluative processes determine the perceived value of the source of social information. The interplay between attention and these three routes of processing places attention in a powerful role to manage the selection of the vast amount of social information that individuals encounter on a daily basis and, in turn, gate the selection of social interactions. © 2018 New York Academy of Sciences.

People with social communication difficulties tend to have superior skills using computers, and as a result computer-based social skills training systems are flourishing. Social skills training, performed by human trainers, is a well-established method to obtain appropriate skills in social interaction. Previous works have attempted to automate one or several parts of social skills training through human-computer interaction. However, while previous work on simulating social skills training considered only acoustic and linguistic features, human social skills trainers take into account visual features (e.g. facial expression, posture). In this paper, we create and evaluate a social skills training system that closes this gap by considering audiovisual features regarding ratio of smiling, yaw, and pitch. An experimental evaluation measures the difference in effectiveness of social skill training when using audio features and audiovisual features. Results showed that the visual features were effective to improve users' social skills.

Journey to the Edges: Social Structures and Neural Maps of Intergroup Processes

Fiske, Susan T.

2013-01-01

This article explores boundaries of the intellectual map of intergroup processes, going to the macro (social structure) boundary and the micro (neural systems) boundary. Both are illustrated by with my own and others’ work on social structures and on neural structures related to intergroup processes. Analyzing the impact of social structures on intergroup processes led to insights about distinct forms of sexism and underlies current work on forms of ageism. The stereotype content model also starts with the social structure of intergroup relations (interdependence and status) and predicts images, emotions, and behaviors. Social structure has much to offer the social psychology of intergroup processes. At the other, less explored boundary, social neuroscience addresses the effects of social contexts on neural systems relevant to intergroup processes. Both social structural and neural analyses circle back to traditional social psychology as converging indicators of intergroup processes. PMID:22435843

Social customer relationship management: taking advantage of Web 2.0 and Big Data technologies.

2016-01-01

The emergence of Web 2.0 and Big Data technologies has allowed a new customer relationship strategy based on interactivity and collaboration called Social Customer Relationship Management (Social CRM) to be created. This enhances customer engagement and satisfaction. The implementation of Social CRM is a complex task that involves different organisational, human and technological aspects. However, there is a lack of methodologies to assist companies in these processes. This paper shows a novel methodology that helps companies to implement Social CRM, taking into account different aspects such as social customer strategy, the Social CRM performance measurement system, the Social CRM business processes, or the Social CRM computer system. The methodology was applied to one company in order to validate and refine it.

Concept mapping for virtual rehabilitation and training of the blind.

Concept mapping is a technique that allows for the strengthening of the learning process, based on graphic representations of the learner's mental schemes. However, due to its graphic nature, it cannot be utilized by learners with visual disabilities. In response to this limitation we implemented a study that involves the design of AudiodMC, an audio-based, virtual environment for concept mapping designed for use by blind users and aimed at virtual training and rehabilitation. We analyzed the stages involved in the design of AudiodMC from a user-centered design perspective, considering user involvement and usability testing. These include an observation stage to learn how blind learners construct conceptual maps using concrete materials, a design stage to design of a software tool that aids blind users in creating concept maps, and a cognitive evaluation stage using AudiodMC. We also present the results of a study implemented in order to determine the impact of the use of this software on the development of essential skills for concept mapping (association, classification, categorization, sorting and summarizing). The results point to a high level of user acceptance, having identified key sound characteristics that help blind learners to learn concept codification and selection skills. The use of AudiodMC also allowed for the effective development of the skills under review in our research, thus facilitating meaningful learning.

DC Electric Fields at the Magnetopause

NASA Astrophysics Data System (ADS)

Laakso, H. E.; Escoubet, C. P.; Masson, A.

2014-12-01

In order to understand the transfer of energy, momentum and mass through the magnetopause one needs to know several plasma and field parameters including the DC electric field which is known to be challenging to measure in tenuous plasma regions, e.g. in the inner side of the magnetopause where the density drops below 1/cc. However, each of the Cluster spacecraft carries five different experiments that can provide information about DC electric fields, i.e. double probe antenna (EFW) and electron drift meter (EDI) as well as electron and ion spectrometers (PEACE, CIS-HIA, CIS-CODIF). Each technique is very different and has its own strengths and limitations. Therefore it is important to compare all available measurements before making a judgement on DC electric field variation at the magnetopause; note that only very rarely all five measurements are available at the same time. Although the full-resolution observations in the Cluster archive are calibrated, they can still contain various errors. However, when two experiments show the same field, it is quite likely that this is the right field because the different measurements are based on so complimentary techniques and the field varies so much when the spacecraft moves from the magnetosheath through the magnetopause into the magnetosphere, or vice versa. In this presentation we present several cases of the magnetopause crossings and how the different measurements agree and disagree around the magnetopause region.

Rising rates of diabetes in pregnancy have led to an escalation in research in this area. As in any area of clinical research, definitions of outcomes vary from study to study, making it difficult to compare research findings and draw conclusions. Our aim was to compile and create a repository of definitions, which could then be used universally. A systematic review of the literature was performed on published and ongoing randomized controlled trials in the area of diabetes in pregnancy between 01 Jan 2000 and 01 Jun 2012. Other sources included the World Health Organization and Academic Society Statements. The advice of experts was sought when appropriate definitions were lacking. Among the published randomized controlled trials on diabetes and pregnancy, 171 abstracts were retrieved, 64 full texts were reviewed and 53 were included. Among the ongoing randomized controlled trials published in ClinicalTrials.gov, 90 protocols were retrieved and 25 were finally included. The definitions from these were assembled and the final maternal definitions and foetal definitions were agreed upon by consensus. It is our hope that the definitions we have provided (i) will be widely used in the reporting of future studies in the area of diabetes in pregnancy, that they will (ii) facilitate future systematic reviews and formal meta analyses and (iii) ultimately improve outcomes for mothers and babies.

For decades, the greater part of efforts to improve regulatory frameworks for research ethics has focused on informed consent procedures; their design, codification and regulation. Why is informed consent thought to be so important? Since the publication of the Belmont Report in 1979, the standard response has been that obtaining informed consent is a way of treating individuals as autonomous agents. Despite its political success, the philosophical validity of this Belmont view cannot be taken for granted. If the Belmont view is to be based on a conception of autonomy that generates moral justification, it will either have to be reinterpreted along Kantian lines or coupled with a something like Mill's conception of individuality. The Kantian interpretation would be a radical reinterpretation of the Belmont view, while the Millian justification is incompatible with the liberal requirement that justification for public policy should be neutral between controversial conceptions of the good. This consequence might be avoided by replacing Mill's conception of individuality with a procedural conception of autonomy, but I argue that the resulting view would in fact fail to support a non-Kantian, autonomy-based justification of informed consent. These difficulties suggest that insofar as informed consent is justified by respect for persons and considerations of autonomy, as the Belmont report maintained, the justification should be along the lines of Kantian autonomy and not individual autonomy.

Semiempirical prediction of protein folds

NASA Astrophysics Data System (ADS)

Fernández, Ariel; Colubri, Andrés; Appignanesi, Gustavo

2001-08-01

We introduce a semiempirical approach to predict ab initio expeditious pathways and native backbone geometries of proteins that fold under in vitro renaturation conditions. The algorithm is engineered to incorporate a discrete codification of local steric hindrances that constrain the movements of the peptide backbone throughout the folding process. Thus, the torsional state of the chain is assumed to be conditioned by the fact that hopping from one basin of attraction to another in the Ramachandran map (local potential energy surface) of each residue is energetically more costly than the search for a specific (Φ, Ψ) torsional state within a single basin. A combinatorial procedure is introduced to evaluate coarsely defined torsional states of the chain defined ``modulo basins'' and translate them into meaningful patterns of long range interactions. Thus, an algorithm for structure prediction is designed based on the fact that local contributions to the potential energy may be subsumed into time-evolving conformational constraints defining sets of restricted backbone geometries whereupon the patterns of nonbonded interactions are constructed. The predictive power of the algorithm is assessed by (a) computing ab initio folding pathways for mammalian ubiquitin that ultimately yield a stable structural pattern reproducing all of its native features, (b) determining the nucleating event that triggers the hydrophobic collapse of the chain, and (c) comparing coarse predictions of the stable folds of moderately large proteins (N~100) with structural information extracted from the protein data bank.

An alternative approach for neural network evolution with a genetic algorithm: crossover by combinatorial optimization.

PubMed

García-Pedrajas, Nicolás; Ortiz-Boyer, Domingo; Hervás-Martínez, César

2006-05-01

In this work we present a new approach to crossover operator in the genetic evolution of neural networks. The most widely used evolutionary computation paradigm for neural network evolution is evolutionary programming. This paradigm is usually preferred due to the problems caused by the application of crossover to neural network evolution. However, crossover is the most innovative operator within the field of evolutionary computation. One of the most notorious problems with the application of crossover to neural networks is known as the permutation problem. This problem occurs due to the fact that the same network can be represented in a genetic coding by many different codifications. Our approach modifies the standard crossover operator taking into account the special features of the individuals to be mated. We present a new model for mating individuals that considers the structure of the hidden layer and redefines the crossover operator. As each hidden node represents a non-linear projection of the input variables, we approach the crossover as a problem on combinatorial optimization. We can formulate the problem as the extraction of a subset of near-optimal projections to create the hidden layer of the new network. This new approach is compared to a classical crossover in 25 real-world problems with an excellent performance. Moreover, the networks obtained are much smaller than those obtained with classical crossover operator.

Medical policy development for human spaceflight at NASA: an evolution.

PubMed

Doarn, Charles R

2011-11-01

Codification of medical policy for the National Aeronautics and Space Administration (NASA) did not occur until 1977. Policy development was based on NASA's human spaceflight efforts from 1958, and the need to support the operational aspects of the upcoming Space Shuttle Program as well as other future activities. In 1958, the Space Task Group (STG), a part of the National Advisory Committee on Aeronautics (NACA), became the focal point for astronaut selection, medical support, and instrumentation development in support of Project Mercury. NACA transitioned into NASA in 1958. The STG moved to Houston, TX, in 1961 and became the Manned Spacecraft Center. During these early years, medical support for astronaut selection and healthcare was provided through arrangements with the U.S. military, specifically the United States Air Force, which had the largest group of subject matter experts in aerospace medicine. Through most of the 1960s, the military worked very closely with NASA in developing the foundations of bioastronautics and space medicine. This work was complemented by select individuals from outside the government. From 1958 to 1977, there was no standard approach to medical policy formulation within NASA. During this time, it was individualized and subjected to political pressures. This manuscript documents the evolution of medical policy in the NASA, and provides a historical account of the individuals, processes, and needs to develop policy.

To determine the perception and self-assessment on leadership among health care team leaders in Andalusia. Design: Exploratory descriptive study using quantitative and qualitative methodology, developed between 2013 and 2015, using a questionnaire and semi-structured interviews. Andalusia. All health managers from the Primary Care Management Units and Health Management Areas of the Departments of Paediatrics, Emergency and Internal Medicine, for the quantitative study. A purposive sample of 24 health managers was used for the qualitative study. Descriptive statistical study and bivariate analysis of comparison of means. Content analysis of the semi-structured interviews: Codification, category tree, and triangulation of results. The best self-assessment dimension relates to support, and the worst to considering oneself as a 'good leader'. The definition of a 'good leader' includes: Honesty, trust, and attitudes of good communication, closeness, appreciation, and reinforcement of the health team members. Different leadership styles were perceived. Main difficulties for leadership are related to the economic crisis and the management of personal conflicts. Health managers describe an adaptive leadership style, based on personal and professional support, and using communication as the main cohesive element for the team project. More studies on leaders' perspectives are important, in order to better understand their experiences, needs and expectations. Copyright © 2016 SECA. Publicado por Elsevier España, S.L.U.

What's your strategy for managing knowledge?

PubMed

Hansen, M T; Nohria, N; Tierney, T

1999-01-01

The rise of the computer and the increasing importance of intellectual assets have compelled executives to examine the knowledge underlying their businesses and how it is used. Because knowledge management as a conscious practice is so young, however, executives have lacked models to use as guides. To help fill that gap, the authors recently studied knowledge management practices at management consulting firms, health care providers, and computer manufacturers. They found two very different knowledge management strategies in place. In companies that sell relatively standardized products that fill common needs, knowledge is carefully codified and stored in databases, where it can be accessed and used--over and over again--by anyone in the organization. The authors call this the codification strategy. In companies that provide highly customized solutions to unique problems, knowledge is shared mainly through person-to-person contacts; the chief purpose of computers is to help people communicate. They call this the personalization strategy. A company's choice of knowledge management strategy is not arbitrary--it must be driven by the company's competitive strategy. Emphasizing the wrong approach or trying to pursue both can quickly undermine a business. The authors warn that knowledge management should not be isolated in a functional department like HR or IT. They emphasize that the benefits are greatest--to both the company and its customers--when a CEO and other general managers actively choose one of the approaches as a primary strategy.

Confessions of the flesh and biopedagogies: discursive constructions of obesity on Nip/Tuck.

PubMed

Rail, G; Lafrance, M

2009-12-01

Informed by the work of Michel Foucault, the authors discuss the Nip/Tuck episode entitled "Momma Boone" and how it discursively constructs "obesity". They show how this popular media text can be understood as a crystallisation of the dominant discourse surrounding fat bodies. In the process, how the episode can be seen as a "biopedagogy" that instructs its viewers in how to think and feel about the fat body is examined. Foucault's formulation of the confessional is seen to be useful to theorise the ways in which biopedagogy leads subjects to believe and ultimately take part in processes leading to salvation. It is argued that in this Nip/Tuck episode, biopedagogy functions in and through Momma Boone's "confessions of the flesh", that is, confessions aimed at revealing her obese body so that it can be rescued, rehabilitated and saved. Momma Boone's salvation is shown to require three stages: first, the "confession" of obesity; second, the conversion to the "truth" of the "dominant obesity discourse"; and third, the codification of a "new life" for the obese subject. In the end, it is argued that since it is represented as abject, monstrous and out of control, Momma Boone's body is made to inspire fear and panic in so far as it provides constructed "evidence" regarding the consequences of the obese subject's failure to convert to the truth of obesity discourse.

Nonbinding Legal Instruments in Governance for Global Health: Lessons from the Global AIDS Reporting Mechanism.

2014-01-01

Recent debate over World Health Organization reform has included unprecedented attention to international lawmaking as a future priority function of the Organization. However, the debate is largely focused on the codification of new binding legal instruments. Drawing upon lessons from the success of the Global AIDS Reporting Mechanism, established pursuant to the United Nations' Declaration of Commitment on HIV/AIDS, we argue that effective global health governance requires consideration of a broad range of instruments, both binding and nonbinding. A detailed examination of the Global AIDS Reporting Mechanism reveals that the choice of the nonbinding format makes an important contribution to its effectiveness. For instance, the flexibility and adaptability of the nonbinding format have allowed the global community to: (1) undertake commitments in a timely manner; (2) adapt and experiment in the face of a dynamic pandemic; and (3) grant civil society an unparalleled role in monitoring and reporting on state implementation of global commitments. UNAIDS' institutional support has also played a vital role in ensuring the continuing effectiveness of the Global AIDS Reporting Mechanism. Overall, the experience of the Global AIDS Reporting Mechanism evidences that, at times, nimbler nonbinding instruments can offer benefits over slower, more rigid binding legal approaches to governance, but depend critically, like all instruments, on the perceived legitimacy thereof. © 2014 American Society of Law, Medicine & Ethics, Inc.

Dealing with health and disease is an area of concern for social workers. The establishment of medical social service in a health setting has more than 100 years of history in the USA and more than 60 years in Hong Kong. Despite the increasing popularity of Chinese Medicine (CM) used by the Hong Kong people, there has been no medical social service presence in the CM system. A pilot project demonstrated a successful interdisciplinary collaboration model between social work and CM irrespective of different social work methods, that is, individual work, groupwork, and community-based services. In this article, we will relate the opportunities and difficulties that we encountered in setting up the first medical social service in the CM system. Drawing on our experience, we found that both professions benefited from the interdisciplinary collaboration. CM was able to expand its scope of service to increase the service quality and promote primary health care in the community with the support of social work. Conversely, social workers found that CM is a good resource for providing innovative services to meet the various needs of the people in the community. There was also a ripple effect of incorporating CM elements into social service. The interface between the disciplines of social work and CM can widen the scope of their contributions on health. Implications for CM social service in social work will also be examined.

Data-Centric Situational Awareness and Management in Intelligent Power Systems

NASA Astrophysics Data System (ADS)

Dai, Xiaoxiao

The rapid development of technology and society has made the current power system a much more complicated system than ever. The request for big data based situation awareness and management becomes urgent today. In this dissertation, to respond to the grand challenge, two data-centric power system situation awareness and management approaches are proposed to address the security problems in the transmission/distribution grids and social benefits augmentation problem at the distribution-customer lever, respectively. To address the security problem in the transmission/distribution grids utilizing big data, the first approach provides a fault analysis solution based on characterization and analytics of the synchrophasor measurements. Specically, the optimal synchrophasor measurement devices selection algorithm (OSMDSA) and matching pursuit decomposition (MPD) based spatial-temporal synchrophasor data characterization method was developed to reduce data volume while preserving comprehensive information for the big data analyses. And the weighted Granger causality (WGC) method was investigated to conduct fault impact causal analysis during system disturbance for fault localization. Numerical results and comparison with other methods demonstrate the effectiveness and robustness of this analytic approach. As more social effects are becoming important considerations in power system management, the goal of situation awareness should be expanded to also include achievements in social benefits. The second approach investigates the concept and application of social energy upon the University of Denver campus grid to provide management improvement solutions for optimizing social cost. Social element--human working productivity cost, and economic element--electricity consumption cost, are both considered in the evaluation of overall social cost. Moreover, power system simulation, numerical experiments for smart building modeling, distribution level real-time pricing and social response to the pricing signals are studied for implementing the interactive artificial-physical management scheme.

Neural mechanisms tracking popularity in real-world social networks

Zerubavel, Noam; Bearman, Peter S.; Weber, Jochen; Ochsner, Kevin N.

2015-01-01

Differences in popularity are a key aspect of status in virtually all human groups and shape social interactions within them. Little is known, however, about how we track and neurally represent others’ popularity. We addressed this question in two real-world social networks using sociometric methods to quantify popularity. Each group member (perceiver) viewed faces of every other group member (target) while whole-brain functional MRI data were collected. Independent functional localizer tasks were used to identify brain systems supporting affective valuation (ventromedial prefrontal cortex, ventral striatum, amygdala) and social cognition (dorsomedial prefrontal cortex, precuneus, temporoparietal junction), respectively. During the face-viewing task, activity in both types of neural systems tracked targets’ sociometric popularity, even when controlling for potential confounds. The target popularity–social cognition system relationship was mediated by valuation system activity, suggesting that observing popular individuals elicits value signals that facilitate understanding their mental states. The target popularity–valuation system relationship was strongest for popular perceivers, suggesting enhanced sensitivity to differences among other group members’ popularity. Popular group members also demonstrated greater interpersonal sensitivity by more accurately predicting how their own personalities were perceived by other individuals in the social network. These data offer insights into the mechanisms by which status guides social behavior. PMID:26598684

Medical social workers apply the theories of "person in the environment" (PIE) and "ecological perspective" as practical foundations. Furthermore, they emphasize the people, the environment, and the interactions between these two. When burn patients from the explosion at Formosa Fun Coast were sent to hospitals, social workers not only provided care and assessed the impact on burn patients but also assisted in supporting the family members of these patients. This article discusses the various roles of social workers within different systems. In the individual system, we use Eric Erickson's theory of psychosocial development to evaluate the patient's crisis and the tasks of social workers. Secondly, in the systems of family, school, and work, we assess the relationships between a patient, his/her significant others, and caregivers as well as the interactions among sub-systems in the family. In the community and cultural systems, we focus on the social resources that may be utilized by the burn patients after discharge. Moreover, we add a time frame to examine our major tasks, including the initial stage, the middle stage, and the preparation-for-discharge stage. We explore the roles of social workers, the applicable theories, and the goals for each stage.

Contact structure, mobility, environmental impact and behaviour: the importance of social forces to infectious disease dynamics and disease ecology

PubMed Central

Gurley, Emily S.

2017-01-01

Human factors, including contact structure, movement, impact on the environment and patterns of behaviour, can have significant influence on the emergence of novel infectious diseases and the transmission and amplification of established ones. As anthropogenic climate change alters natural systems and global economic forces drive land-use and land-cover change, it becomes increasingly important to understand both the ecological and social factors that impact infectious disease outcomes for human populations. While the field of disease ecology explicitly studies the ecological aspects of infectious disease transmission, the effects of the social context on zoonotic pathogen spillover and subsequent human-to-human transmission are comparatively neglected in the literature. The social sciences encompass a variety of disciplines and frameworks for understanding infectious diseases; however, here we focus on four primary areas of social systems that quantitatively and qualitatively contribute to infectious diseases as social–ecological systems. These areas are social mixing and structure, space and mobility, geography and environmental impact, and behaviour and behaviour change. Incorporation of these social factors requires empirical studies for parametrization, phenomena characterization and integrated theoretical modelling of social–ecological interactions. The social–ecological system that dictates infectious disease dynamics is a complex system rich in interacting variables with dynamically significant heterogeneous properties. Future discussions about infectious disease spillover and transmission in human populations need to address the social context that affects particular disease systems by identifying and measuring qualitatively important drivers. This article is part of the themed issue ‘Opening the black box: re-examining the ecology and evolution of parasite transmission’. PMID:28289265

Discrimination against Rural-to-Urban Migrants: The Role of the Hukou System in China

PubMed Central

Kuang, Lei; Liu, Li

2012-01-01

China's rural-urban dual society system is instituted by its unique hukou system. This system causes inequalities in social status between permanent urban and rural residents, and discrimination against rural-to-urban migrants is thus prevalent. A series of studies, based on system justification theory, sought to address the impact of the hukou system on the discrimination against rural-to-urban migrants. Study 1 showed that the justification of the hukou system could predict discrimination operationalized using a social distance measure. Study 2 found that priming of the proposed abolishment of the current hukou system led to reduced social distance. Study 3, using a recruiting scenario, further demonstrated that priming of the proposed abolishment of the system led to reduced discrimination in salary decision. Consistent with our predictions, discrimination against rural-to-urban migrants could be triggered by justifying the current hukou system, while priming of the abolishment of the system serves to decrease discrimination. The present research thereby sheds light on China's reform of its hukou system to achieve social justice and equality from a psychological perspective. PMID:23144794

Social media are increasingly being used for educational purposes. The first part of this article briefly reviews literature that reports on educational applications of social media tools. The second part discusses theories that may provide a basis for analyzing the processes that are relevant for individual learning and collective knowledge construction. We argue that a systems-theoretical constructivist approach is appropriate to examine the processes of educational social media use, namely, self-organization, the internalization of information, the externalization of knowledge, and the interplay of externalization and internalization providing the basis of a co-evolution of cognitive and social systems. In the third part we present research findings that illustrate and support this systems-theoretical framework. Concluding, we discuss the implications for educational design and for future research on learning and collective knowledge construction with social media. PMID:26246643

2010-01-01

We present a model for HIV-related behaviors that emphasizes the dynamic and social nature of the structural factors that influence HIV prevention and detection. Key structural dimensions of the model include resources, science and technology, formal social control, informal social influences and control, social interconnectedness, and settings. These six dimensions can be conceptualized on macro, meso, and micro levels. Given the inherent complexity of structural factors and their interrelatedness, HIV prevention interventions may focus on different levels and dimensions. We employ a systems perspective to describe the interconnected and dynamic processes of change among social systems and their components. The topics of HIV testing and safer injection facilities are analyzed using this structural framework. Finally, we discuss methodological issues in the development and evaluation of structural interventions for HIV prevention and detection. PMID:20838871

Brain oxytocin in social fear conditioning and its extinction: involvement of the lateral septum.

PubMed

Zoicas, Iulia; Slattery, David A; Neumann, Inga D

2014-12-01

Central oxytocin (OXT) has anxiolytic and pro-social properties both in humans and rodents, and has been proposed as a therapeutic option for anxiety and social dysfunctions. Here, we utilized a mouse model of social fear conditioning (SFC) to study the effects of OXT on social fear, and to determine whether SFC causes alterations in central OXT receptor (OXTR) binding and local OXT release. Central infusion of OXT, but not arginine vasopressin, prior to social fear extinction training completely abolished social fear expression in an OXTR-mediated fashion without affecting general anxiety or locomotion. SFC caused increased OXTR binding in the dorso-lateral septum (DLS), central amygdala, dentate gyrus, and cornu ammunis 1, which normalized after social fear extinction, suggesting that these areas form part of a brain network involved in the development and neural support of social fear. Microdialysis revealed that the increase in OXT release observed in unconditioned mice within the DLS during social fear extinction training was attenuated in conditioned mice. Consequently, increasing the availability of local OXT by infusion of OXT into the DLS reversed social fear. Thus, alterations in the brain OXT system, including altered OXTR binding and OXT release within the DLS, play an important role in SFC and social fear extinction. Thus, we suggest that the OXT system is adversely affected in disorders associated with social fear, such as social anxiety disorder and reinstalling an appropriate balance of the OXT system may alleviate some of the symptoms.

Black-Right-Pointing-Pointer We develop a model for assessing the social performance of CWM. Black-Right-Pointing-Pointer With the model, the social performance of CWM can be quantitatively simulated. - Abstract: It has been determined by existing literature that a lot of research efforts have been made to the economic performance of construction waste management (CWM), but less attention is paid to investigation of the social performance of CWM. This study therefore attempts to develop a model for quantitatively evaluating the social performance of CWM by using a system dynamicsmore » (SD) approach. Firstly, major variables affecting the social performance of CWM are identified and a holistic system for assessing the social performance of CWM is formulated in line with feedback relationships underlying these variables. The developed system is then converted into a SD model through the software iThink. An empirical case study is finally conducted to demonstrate application of the model. Results of model validation indicate that the model is robust and reasonable to reflect the situation of the real system under study. Findings of the case study offer helpful insights into effectively promoting the social performance of CWM of the project investigated. Furthermore, the model exhibits great potential to function as an experimental platform for dynamically evaluating effects of management measures on improving the social performance of CWM of construction projects.« less

Early Warning Signals of Social Transformation: A Case Study from the US Southwest.

Spielmann, Katherine A; Peeples, Matthew A; Glowacki, Donna M; Dugmore, Andrew

2016-01-01

Recent research in ecology suggests that generic indicators, referred to as early warning signals (EWS), may occur before significant transformations, both critical and non-critical, in complex systems. Up to this point, research on EWS has largely focused on simple models and controlled experiments in ecology and climate science. When humans are considered in these arenas they are invariably seen as external sources of disturbance or management. In this article we explore ways to include societal components of socio-ecological systems directly in EWS analysis. Given the growing archaeological literature on 'collapses,' or transformations, in social systems, we investigate whether any early warning signals are apparent in the archaeological records of the build-up to two contemporaneous cases of social transformation in the prehistoric US Southwest, Mesa Verde and Zuni. The social transformations in these two cases differ in scope and severity, thus allowing us to explore the contexts under which warning signals may (or may not) emerge. In both cases our results show increasing variance in settlement size before the transformation, but increasing variance in social institutions only before the critical transformation in Mesa Verde. In the Zuni case, social institutions appear to have managed the process of significant social change. We conclude that variance is of broad relevance in anticipating social change, and the capacity of social institutions to mitigate transformation is critical to consider in EWS research on socio-ecological systems.

The co-occurrence of zinc deficiency and social isolation has the opposite effects on mood compared with either condition alone due to changes in the central norepinephrine system.

Nutritional and social environmental problems during the early stages of life are closely associated with the pathophysiology of mood disorders such as depression. Disruption or dysfunction of the central norepinephrine (NE) system is also considered to play a role in mood disorders. Therefore, we evaluated the effects of zinc deficiency and/or social isolation on mood and changes in the central NE system using rats. Compared with the controls, the rats subjected to zinc deficiency or social isolation alone exhibited increased anxiety-related behavior in the elevated plus maze and greater depression-like behavior in the forced swim test. However, the co-occurrence of zinc deficiency and social isolation resulted in decreased anxiety-related behavior and control levels of depression-like behavior. Social isolation alone decreased the rats' cerebral NE concentrations. The expression of the NE transporter was not affected by social isolation alone, but its expression in the locus coeruleus was markedly decreased by the co-occurrence of social isolation and zinc deficiency, and this change was accompanied by an increase in the blood concentration of 3-methoxy-4-hydroxyphenylglycol, which is a marker of central NE system activity. These findings suggest that zinc deficiency or social isolation alone induce anxious or depressive symptoms, but the presence of both conditions has anxiolytic or antidepressive effects. Furthermore, these opposing effects of mood-related behaviors were found to be associated with changes in the central NE system. Copyright © 2015 The Authors. Published by Elsevier B.V.

Early-Life Social Isolation Impairs the Gonadotropin-Inhibitory Hormone Neuronal Activity and Serotonergic System in Male Rats.

Social isolation in early life deregulates the serotonergic system of the brain, compromising reproductive function. Gonadotropin-inhibitory hormone (GnIH) neurons in the dorsomedial hypothalamic nucleus are critical to the inhibitory regulation of gonadotropin-releasing hormone neuronal activity in the brain and release of luteinizing hormone by the pituitary gland. Although GnIH responds to stress, the role of GnIH in social isolation-induced deregulation of the serotonin system and reproductive function remains unclear. We investigated the effect of social isolation in early life on the serotonergic-GnIH neuronal system using enhanced green fluorescent protein (EGFP)-tagged GnIH transgenic rats. Socially isolated rats were observed for anxious and depressive behaviors. Using immunohistochemistry, we examined c-Fos protein expression in EGFP-GnIH neurons in 9-week-old adult male rats after 6 weeks post-weaning isolation or group housing. We also inspected serotonergic fiber juxtapositions in EGFP-GnIH neurons in control and socially isolated male rats. Socially isolated rats exhibited anxious and depressive behaviors. The total number of EGFP-GnIH neurons was the same in control and socially isolated rats, but c-Fos expression in GnIH neurons was significantly reduced in socially isolated rats. Serotonin fiber juxtapositions on EGFP-GnIH neurons were also lower in socially isolated rats. In addition, levels of tryptophan hydroxylase mRNA expression in the dorsal raphe nucleus were significantly attenuated in these rats. These results suggest that social isolation in early-life results in lower serotonin levels, which reduce GnIH neuronal activity and may lead to reproductive failure.

Hoffmann, H

1994-01-01

As generally in psychiatry the treatment concepts in social psychiatry base to a great extend on disease- and deficit models. These models, however, have their limits and run the risk to promote exactly that, what social psychiatry is fighting against: chronification. The question shall be discussed, if the systemic approach could be helpful to reduce (social) psychiatry's contribution on the process of chronification. Since ever psychiatric institutions have the mandate of social control and exclusion of social disturbing people from society. On the other hand, social support has become a cornerstone of rehabilitation in psychiatry. There the therapist becomes the manager of the disability. The (case-)manager subsequently takes over the responsibility for the future course. So he also gets power over the system to be treated. He decides, how much of social support and control is necessary. But then he gives up the aim of profoundly changing something in the sense that the patient can give up his symptoms and take more self-responsibility for his acting. The consequence is that the patient and psychiatry keep up each other: a coevolution develops. This leads to rigidity and makes changes difficult. By taking over responsibility the therapist becomes part of the system to be treated. So he looses his neutrality and also the possibility of therapeutical influence and change. The whole system quickly moves into a vicious circle of helplessness. Finally it will be reflected how someone, working in an institution, still can do therapy in this field of tension of (social) psychiatry.

Abstract Social anxiety was compared between online and real-life interaction in a sample of 2,348 college students. Severity of social anxiety in both real-life and online interaction was tested for associations with depression, Internet addiction, Internet activity type (gaming versus chatting), and scores on Behavioral Inhibition System (BIS)/Behavioral Activation System (BAS) scales. The results showed that social anxiety was lower when interacting online than when interacting offline. Depression, Internet addiction, and high BIS and BAS scores were associated with high social anxiety. The social anxiety decreased more in online interaction among subjects with high social anxiety, depression, BIS, and BAS. This result suggests that the Internet has good potential as an alternative medium for delivering interventions for social anxiety. Further, the effect of BIS on social anxiety is decreased in online interaction. More attention should be paid for BIS when the treatment for social anxiety is delivered online. PMID:22175853

With reference to the national health systems in Germany and the UK we must acknowledge that it was in particular Bismarck's Reform, originally directed toward a solidarity among the socially weak, which entailed in its development a marked redistribution via progressive health fees and standardized health services. In view of Alfred Marshall's original expectations this has resulted in a specific integration of the socially weak and with some difference for nationally tax-financed and social security financed health systems to a genuine contribution towards integration of modern society. An open research question is whether as a consequence of solidarity and integration through health systems there is a decline of social inequality for health. Equally open is the question as to the socio-structural and economic consequences the expansion of modern health systems has.

Social Brains in Context: Lesions Targeted to the Song Control System in Female Cowbirds Affect Their Social Network

Social experiences can organize physiological, neural, and reproductive function, but there are few experimental preparations that allow one to study the effect individuals have in structuring their social environment. We examined the connections between mechanisms underlying individual behavior and social dynamics in flocks of brown-headed cowbirds (Molothrus ater). We conducted targeted inactivations of the neural song control system in female subjects. Playback tests revealed that the lesions affected females' song preferences: lesioned females were no longer selective for high quality conspecific song. Instead, they reacted to all cowbird songs vigorously. When lesioned females were introduced into mixed-sex captive flocks, they were less likely to form strong pair-bonds, and they no longer showed preferences for dominant males. This in turn created a cascade of effects through the groups. Social network analyses showed that the introduction of the lesioned females created instabilities in the social structure: males in the groups changed their dominance status and their courtship patterns, and even the competitive behavior of other female group-mates was affected. These results reveal that inactivation of the song control system in female cowbirds not only affects individual behavior, but also exerts widespread effects on the stability of the entire social system.

The human reward system is sensitive to both social (e.g., validation) and non-social rewards (e.g., money) and is likely integral for relationship development and reputation building. However, data is sparse on the question of whether implicit social reward processing meaningfully contributes to explicit social representations such as trust and attachment security in pre-existing relationships. This event-related fMRI experiment examined reward system prediction-error activity in response to a potent social reward-social validation-and this activity's relation to both attachment security and trust in the context of real romantic relationships. During the experiment, participants' expectations for their romantic partners' positive regard of them were confirmed (validated) or violated, in either positive or negative directions. Primary analyses were conducted using predefined regions of interest, the locations of which were taken from previously published research. Results indicate that activity for mid-brain and striatal reward system regions of interest was modulated by social reward expectation violation in ways consistent with prior research on reward prediction-error. Additionally, activity in the striatum during viewing of disconfirmatory information was associated with both increases in post-scan reports of attachment anxiety and decreases in post-scan trust, a finding that follows directly from representational models of attachment and trust.

The mirror mechanism and mu rhythm in social development.

Vanderwert, Ross E; Fox, Nathan A; Ferrari, Pier F

2013-04-12

Since the discovery of mirror neurons (MNs) in the monkey there has been a renewed interest in motor theories of cognitive and social development in humans by providing a potential neural mechanism underlying an action observation/execution matching system. It has been proposed that this system plays a fundamental role in the development of complex social and cognitive behaviors such as imitation and action recognition. In this review we discuss what is known about MNs from the work using single-cell recordings in the adult monkey, the evidence for the putative MN system in humans, and the extent to which research using electroencephalography (EEG) methods has contributed to our understanding of the development of these motor systems and their role in the social behaviors postulated by the MN hypothesis. We conclude with directions for future research that will improve our understanding of the putative human MN system and the functional role of MNs in social development.

Social instability and immunity in rhesus monkeys: the role of the sympathetic nervous system.

PubMed

Capitanio, John P; Cole, Steven W

2015-05-26

Social instability can adversely affect endocrine, immune and health outcomes, and recent evidence suggests that the sympathetic nervous system (SNS) might mediate these effects. We conducted two studies with adult male rhesus monkeys (Macaca mulatta) to understand how social conditions affect measures of SNS activity and immune function. In Experiment 1, animals were socialized in stable social conditions, then were switched to unstable (stressful) social conditions, then were returned to stable conditions. Analysis revealed quadratic effects for measures of behaviour, urinary metabolites of epinephrine and norepinephrine, and expression of immune response genes: as expected, social instability adversely impacted most measures, and the effects remediated upon re-imposition of stable conditions. Cortisol levels were unaffected. In Experiment 2, we used the sympathomimetic drug methamphetamine to challenge the SNS; animals also underwent socialization in stable or unstable groups. Surprisingly, while methamphetamine elevated plasma catecholamines, responses in lymph nodes tracked the social, and not the drug, condition: social instability upregulated the density of SNS fibres in lymph nodes and downregulated Type I interferon gene expression. Together, these results indicate that the SNS is extremely sensitive to social conditions; full understanding of the adverse effects of social instability on health should therefore incorporate measures of this health-relevant system. © 2015 The Author(s) Published by the Royal Society.

The power of social structure: how we became an intelligent lineage

2011-01-01

New findings pertinent to the human lineage origin (Ardipithecus ramidus) prompt a new analysis of the extrapolation of the social behavior of our closest relatives, the great apes, into human ‘natural social behavior’. With the new findings it becomes clear that human ancestors had very divergent social arrangements from the ones we observe today in our closest genetic relatives. The social structure of chimpanzees and gorillas is characterized by male competition. Aggression and the instigation of fear are common place. The morphology of A. ramidus points in the direction of a social system characterized by female-choice instead of male-male competition. This system tends to be characterized by reduced aggression levels, leading to more stable arrangements. It is postulated here that the social stability with accompanying group cohesion propitiated by this setting is favorable to the investment in more complex behaviors, the development of innovative approaches to solve familiar problems, an increase in exploratory behavior, and eventually higher intelligence and the use of sophisticated tools and technology. The concentration of research efforts into the study of social animals with similar social systems (e.g., New World social monkeys (Callitrichidae), social canids (Canidae) and social rodents (Rodentia)) are likely to provide new insights into the understanding of what factors determined our evolution into an intelligent species capable of advanced technology.

Collective learning for the emergence of social norms in networked multiagent systems.

Yu, Chao; Zhang, Minjie; Ren, Fenghui

2014-12-01

Social norms such as social rules and conventions play a pivotal role in sustaining system order by regulating and controlling individual behaviors toward a global consensus in large-scale distributed systems. Systematic studies of efficient mechanisms that can facilitate the emergence of social norms enable us to build and design robust distributed systems, such as electronic institutions and norm-governed sensor networks. This paper studies the emergence of social norms via learning from repeated local interactions in networked multiagent systems. A collective learning framework, which imitates the opinion aggregation process in human decision making, is proposed to study the impact of agent local collective behaviors on the emergence of social norms in a number of different situations. In the framework, each agent interacts repeatedly with all of its neighbors. At each step, an agent first takes a best-response action toward each of its neighbors and then combines all of these actions into a final action using ensemble learning methods. Extensive experiments are carried out to evaluate the framework with respect to different network topologies, learning strategies, numbers of actions, influences of nonlearning agents, and so on. Experimental results reveal some significant insights into the manipulation and control of norm emergence in networked multiagent systems achieved through local collective behaviors.

Social tagging in the life sciences: characterizing a new metadata resource for bioinformatics.

PubMed

Good, Benjamin M; Tennis, Joseph T; Wilkinson, Mark D

Academic social tagging systems, such as Connotea and CiteULike, provide researchers with a means to organize personal collections of online references with keywords (tags) and to share these collections with others. One of the side-effects of the operation of these systems is the generation of large, publicly accessible metadata repositories describing the resources in the collections. In light of the well-known expansion of information in the life sciences and the need for metadata to enhance its value, these repositories present a potentially valuable new resource for application developers. Here we characterize the current contents of two scientifically relevant metadata repositories created through social tagging. This investigation helps to establish how such socially constructed metadata might be used as it stands currently and to suggest ways that new social tagging systems might be designed that would yield better aggregate products. We assessed the metadata that users of CiteULike and Connotea associated with citations in PubMed with the following metrics: coverage of the document space, density of metadata (tags) per document, rates of inter-annotator agreement, and rates of agreement with MeSH indexing. CiteULike and Connotea were very similar on all of the measurements. In comparison to PubMed, document coverage and per-document metadata density were much lower for the social tagging systems. Inter-annotator agreement within the social tagging systems and the agreement between the aggregated social tagging metadata and MeSH indexing was low though the latter could be increased through voting. The most promising uses of metadata from current academic social tagging repositories will be those that find ways to utilize the novel relationships between users, tags, and documents exposed through these systems. For more traditional kinds of indexing-based applications (such as keyword-based search) to benefit substantially from socially generated metadata in the life sciences, more documents need to be tagged and more tags are needed for each document. These issues may be addressed both by finding ways to attract more users to current systems and by creating new user interfaces that encourage more collectively useful individual tagging behaviour.

Social network supported process recommender system.

Process recommendation technologies have gained more and more attention in the field of intelligent business process modeling to assist the process modeling. However, most of the existing technologies only use the process structure analysis and do not take the social features of processes into account, while the process modeling is complex and comprehensive in most situations. This paper studies the feasibility of social network research technologies on process recommendation and builds a social network system of processes based on the features similarities. Then, three process matching degree measurements are presented and the system implementation is discussed subsequently. Finally, experimental evaluations and future works are introduced.

Predicting the behavior of techno-social systems.

We live in an increasingly interconnected world of techno-social systems, in which infrastructures composed of different technological layers are interoperating within the social component that drives their use and development. Examples are provided by the Internet, the World Wide Web, WiFi communication technologies, and transportation and mobility infrastructures. The multiscale nature and complexity of these networks are crucial features in understanding and managing the networks. The accessibility of new data and the advances in the theory and modeling of complex networks are providing an integrated framework that brings us closer to achieving true predictive power of the behavior of techno-social systems.

The Influential Role of Sociocultural Feedbacks on Community-Managed Irrigation System Behaviors During times of Water Stress

Sociohydrological studies use interdisciplinary approaches to explore the complex interactions between physical and social water systems and increase our understanding of emergent and paradoxical system behaviors. The dynamics of community values and social cohesion, however, have received little attention in modeling studies due to quantification challenges. Social structures associated with community-managed irrigation systems around the world, in particular, reflect these communities' experiences with a multitude of natural and social shocks. Using the Valdez acequia (a communally-managed irrigation community in northern New Mexico) as a simulation case study, we evaluate the impact of that community's social structure in governing its responsesmore » to water availability stresses posed by climate change. Specifically, a system dynamics model (developed using insights from community stakeholders and multiple disciplines that captures biophysical, socioeconomic, and sociocultural dynamics of acequia systems) was used to generate counterfactual trajectories to explore how the community would behave with streamflow conditions expected under climate change. We found that earlier peak flows, combined with adaptive measures of shifting crop selection, allowed for greater production of higher value crops and fewer people leaving the acequia. The economic benefits were lost, however, if downstream water pressures increased. Even with significant reductions in agricultural profitability, feedbacks associated with community cohesion buffered the community's population and land parcel sizes from more detrimental impacts, indicating the community's resilience under natural and social stresses. In conclusion, continued exploration of social structures is warranted to better understand these systems' responses to stress and identify possible leverage points for strengthening community resilience.« less

Community social alarm network in Slovenia.

PubMed

Premik, M; Rudel, D

1996-12-01

The article deals with a case report on the technology transfer of the Lifeline community social alarm system to Slovenia. The main reason the project was initiated is the ageing of the Slovenian population (11% of the population is 65 or over). With this system we intend to support the public's wish to allow the elderly to remain in their own homes for as long as possible instead of placing them in institutional care. Between 1992 and 1995 the following results were achieved: the acceptability of the system in the social environment was increased; a pilot control centre in Ljubljana was established and has been operational for two-and-a-half years; a national dissemination plan was prepared; the integration of the programme into other information systems has been started. One of the main conclusions is that for the successful transfer of a technology which also affects social values in society, a social innovation must support the process.

Relativism and the social scientific study of medicine.

PubMed

Risjord, M

1993-04-01

Does the social scientific study of medicine require a commitment to relativism? Relativism claims that some subject (e.g., knowledge claims or moral judgments) is relative to a background (e.g., a culture or conceptual scheme) and that judgments about the subject are incommensurable. Examining the concept of success as it appears in orthodox and nonorthodox medical systems, we see that judgments of success are relative to a background medical system. Relativism requires the social scientific study of medicine to be value free in the sense that a medical system must be described without evaluating its elements. When social scientists do evaluate the successfulness of a nonorthodox medical system, they give a crucial role to the nonorthodox conception of success. This strategy does not vitiate value-freedom and it entails a relativism about success. The social scientific study of medicine, therefore, does require relativism in the form of a relativism about success.
