    Full Text Available The aim of this study was to classify the behaviour problems of dogs reported by owners in the Bursa region. A survey was conducted with the owners of 80 dogs with behaviour problems in 2000 - 2004. The questionnaire consisted of questions related to the demographics of the problems the owners observed in their dogs. Sixty eight dogs were selected from animals referred to the Clinic of the Internal Medicine Department of the Uludag University, Faculty of Veterinary Medicine and 12 dogs were selected at a private kennel. The 68 dogs diagnosed at the clinic as having behaviour problems represented 6.2% of the 1086 patient dogs older than 6 months seen in the same period. Twelve dogs with behaviour problems were selected from a total of 150 dogs at a private kennel. A total of 110 behavioural problems were detected. Some dogs showed more than one behavioural disorder. The classification of the problems was as follows: 65 dogs (59% with aggression, 13 dogs (12% with separation anxiety, 12 dogs (10.5% with phobia of veterinary clinics and high-volume noises such as thunders and fireworks, 12 dogs (10.5% with compulsive disorders (9 dogs with tail chasing, 2 dogs with lick dermatitis, 1 dog with self mutilation, 4 dogs (4% with inappropriate elimination, 2 dogs (2% with coprophagia, and 1 dog (1% with puppy killing, 1 dog (1% with false pregnancy. The breeds most often presented in our study were: German shepherd (19%, Terrier (18%, mixed breed (15%, Anatolian sheepdog (10%. The results of the study showed that behavioural problems are common among dogs in Bursa and aggression ranks first, followed by separation anxiety, phobia and tail chasing.

    In the development of practices associated with the use of ionizing radiation, while all the required protection and safety measures are taken, there is always a probability of occurrence of situations of accidents for which it must be prepared and organized with a system of emergencies both at the level of regulatory authority and other organizations and of users. In the frames of this system the comprehensive assessment of radiological events constitutes a basic element of feedback for its further development. The objective of this work is to make an analysis of the behavior of the events in Cuba in the period 2000-2004

    A Wetlands Mitigation Bank was established at SRS in 1997 as a compensatory alternative for unavoidable wetland losses. Prior to restoration activities, 16 sites included in the project were surveyed for the SRS Site Use system to serve as a protective covenant. Pre-restoration monitoring ended in Fall 2000, and post restoration monitoring began in the Winter/Spring of 2001. The total interior harvest in the 16 bays after harvesting the trees was 19.6 ha. The margins in the opencanopy, pine savanna margin treatments were thinned. Margins containing areas with immature forested stands (bay 5184 and portions of bay 5011) were thinned using a mechanical shredder in November 2001. Over 126 hectares were included in the study areas (interior + margin). Planting of two tree species and the transplanting of wetland grass species was successful. From field surveys, it was estimated that approximately 2700 Nyssa sylvatica and 1900 Taxodium distichum seedlings were planted in the eight forested bays resulting in an average planting density of ≈ 490 stems ha-1. One hundred seedlings of each species per bay (where available) were marked to evaluate survivability and growth. Wetland grass species were transplanted from donor sites on SRS to plots that ranged in size from 100 – 300 m2, depending on wetland size. On 0.75 and 0.6 meter centers, respectively, 2198 plugs of Panicum hemitomon and 3021 plugs Leersia hexandra were transplanted. New shoots originating from the stumps were treated with a foliar herbicide (Garlon® 4) during the summer of 2001 using backpack sprayers. Preliminary information from 2000-2004 regarding the hydrologic, vegetation and faunal response to restoration is presented in this status report. Post restoration monitoring will continue through 2005. A final report to the Mitigation Bank Review Team will be submitted in mid-2006.

    When ADEME launched its Wood fuel programme throughout all of France in late 1999, its aim was to guide this resource supply chain to maturity and stable development in all user sectors: domestic, multi-family housing, commercial/institutional and industrial applications. To this end the Wood fuel Programme 2000-2006 was assigned objectives and endowed with significant financial means for studies and coordination in order to support and carry out general-interest projects, piloted by ADEME. The stated goal was to replace fossil fuels, avoid carbon emissions and establish quality assurance standards for household firewood and wood-fired devices. This report makes a status of ADEME's Wood fuel programme for the 2000-2004 era: - Domestic heating: After a drop during the 1990's, figures since 1999 of sales of wood-fuel domestic heating equipment (closed heaters, glass-door fires and stoves) have shown a significant rise. On average over 30 years, wood consumption has risen to 7.2 million TOE (40 million cubic metres) per year; - Industry: It is thought there are 1000 wood-fired heaters (above 1 megawatt) used in French industry. These are found mainly in timber-based industries and in timber crushing plants. This amounts to a total power output of 2.5 gigawatts. In the primary and secondary wood processing industries, the increase in the number of wood-fired boilers and energy produced has reached 5% per year Results of a call for carbon energy projects (APEC) was 61 submitted of which 52 were selected; 9 projects pending (166.5 K of aid from ADEME); and 35 projects begun (1,649 K of aid from ADEME). - Local authority and service sector wood-fired heating systems: At the end of 2004, the number of local authority active boilers was 641, producing 430 megawatts. This is an increase of an average of 13% year on year since 2000. By the end of 2004, the target had already been met for the number of boilers being financed (1,090).

    This paper reviews and synthesizes the theory of information economics and empirical evidence on how information changes the behavior of consumers, households and firms. I show that consumers respond to new information in food experiments but perhaps not in retirement account management. Some seeming perverse consumer/investor decision making may be a result of a complex decision with a low expected payoff.

    The human population continues to grow and large parts of the world industrialize rapidly, causing changes in the global atmospheric chemistry. Carbon monoxide (CO) is a poisonous gas in the troposphere when highly concentrated, and is produced by fossil fuel combustion, biomass burning and through natural emissions from plants. It is also an important trace gas in the atmosphere and plays a major role in the atmospheric chemistry. We present a study of CO from the measurement of MOPITT (Measurement of Pollution in the Troposphere-Level 3 gridded data) instrument on NASA Terra satellite over India and Eastern Asia for the period of 2000-2004. Day- and night-time total column CO measurements are considered over the selected regions in India, China, Thailand and Japan. The selected regions comprise of industrial cities in the Asian continent which form the source of high CO in the atmosphere. The time series data do not show an overall increasing or decreasing trend, but CO is affected by seasonal variations, wind, and precipitation patterns. East Asian regions have higher and wider seasonal fluctuations than the Indian region. CO total column values over the Bay of Bengal are also high and can be explained through wind patterns from the land towards the ocean. Although the sources of CO are mostly confined to the land, it is transported globally through the atmosphere, and has high concentrations over the ocean.

  13. Contribution of wind power and CHP to exports from Western Denmark during 2000-2004

    The experience of Denmark is used by the United Kingdom's anti-wind lobby to demonstrate that intermittency and inaccuracies in wind forecasting make wind power ineffective and expensive. A further assertion is that most of the power is 'unwanted' since up to 80% of it is exported. Here, available data for Danish energy production for 2000-2004 is used to assess the link between wind generation and exports and test the validity of these claims. Net exports in Western Denmark showed good correlation with wind production. However, they were more significantly correlated with the production from local combined heat and power (CHP) plants. In order to test the 80% export claim, a simple technique was devised to correlate and rank hourly net exports and generation from wind and local CHP. In the case where net exports were primarily attributed to (or blamed on) wind, 44-84% of annual wind production was deemed to be exported, with wind 'causing' 57-79% of net annual exports. For this extreme scenario, the percentage values are in line with those of critics. However, under the opposite extreme scenario in which exports are attributed to local CHP, 77-94% of exports were caused by CHP and only 4-32% of wind production was exported. Overall, this study shows that there is some degree of correlation between net exports and wind power, but that the claim that 80% is exported is unwarranted since it ignores the demonstrably stronger influence of local CHP.

    Membrane plasma exchange (PE) is a mode of extracorporeal blood purification. Since 1985 membrane PE has been in regular use at the Department of Nephrology, Medical Faculty of Skopje, R.Macedonia. In this paper we report on five years (2000-2004) of single centre plasma exchange activity. We performed 540 PE treatments (108 PE/per year) on 99 patients. The M/F ratio was 40/48. The patients underwent a median of 5.45 procedures (range, 1-16). The treated patients were from different Departments. Protocols for PE depend on the disease and its severity. PE were performed 2-4 times weekly using Gambro PF 2000 N filters with an adaptation of the Gambro AK10 dialysis machine or with the Gambro Prizma machine (2 cases). Blood access was achieved through femoral vein. Substitution was made with fresh frozen plasma and/or with 20% human albumin combined with Ringer's solution. An average amount of 2150 ml plasmafiltrate per treatment (respectively 30 to 40 ml plasmafiltrate/kg body weight) was eliminated. Most therapeutic procedures were performed on patients from the Department of Neurology. 63.6% of all patients were referred for Myasthenia gravis and the Guillian Barre syndrome. The total number of procedures per year has remained fairly stable, corresponding to a median of 5.4 treatments/100 000 inhabitants. We observed hypocalcaemia in 8% of the patients, urticarial reactions in 7.3%, pruritic reactions in 12%, and hypotension/headache in 6.8%. No major procedural complications were seen.

    Particulate air pollution is a serious problem in Beijing. The annual concentration of particulate matter with aerodynamic diameter less than 10 μm (PM 10 ), ranging from 141 to 166 μg m -3 in 2000-2004, could be very harmful to human health. In this paper, we presented the mortality and morbidity effects of PM 10 pollution based on statistical data and the epidemiological exposure-response function. The economic costs to health during the 5 years were estimated to lie between US$1670 and $3655 million annually, accounting for about 6.55% of Beijing's gross domestic product each year. The total costs were apportioned into two parts caused by: the local emissions and long-range transported pollution. The contribution from local emissions dominated the total costs, accounting on average for 3.60% of GDP. However, the contributions from transported pollution cannot be neglected, and the relative percentage to the total costs from the other regions could account for about 45%. An energy policy and effective measures should be proposed to reduce particulate matter, especially PM 2.5 pollution in Beijing to protect public health. The Beijing government also needs to cooperate with the other local governments to reduce high background level of particulate air pollution

    Full Text Available This paper addresses the process of decentralization in Venezuela, under mayors’ perspective, elected for the period 2000-2004. Our main goal is to identify the vision they have over such an important process that theoretically strengthens, supports, and enhances the democratic system. We contrast decentralization theory (which states that if there is not democracy at levels of government closer to the citizens-municipal government-democracy is not sustained over real bases with what Venezuelan mayors exposed about the facts observed in the nation in this sense. Our hypothesis is that the concepts and visions that the mayors expressed must coincide with the theory sustaining decentralization in general and particularly decentralization in Venezuela, which must coincide with their praxis in their municipalities. We concluded that the positive perspectives and visions as the negatives or pessimistic ones stated by the interviewed mayors coincided with theory supporting decentralization in different countries and with the evaluations of decentralization that have been conducted in different nations. Venezuelan decentralization process is not different from those that have been discovered in other countries in this sense. It seems to be that the decentralization policy in Venezuela enjoys the same virtues and suffers the same problems that decentralization policies in other countries. El presente trabajo aborda el proceso de descentralización en Venezuela visto desde la perspectiva de los alcaldes electos para el período 2000-2004. El interés es identificar la visión que tienen éstos sobre tan importante proceso que, teóricamente, sustenta, soporta y fortalece el sistema democrático. Se contrastan los fundamentos teóricos esgrimidos sobre las bondades de las políticas descentralizadoras que parten del supuesto teórico de que si no hay democracia en los niveles del gobierno que están más cerca del ciudadano (el gobierno municipal la

    Breastfeeding is associated with decreased risk for many early-life diseases and conditions, including otitis media, respiratory tract infections, atopic dermatitis, gastroenteritis, type 2 diabetes, sudden infant death syndrome, and obesity. Breastfeeding also is associated with health benefits to women, including decreased risk for type 2 diabetes, ovarian cancer, and breast cancer. Exclusive breastfeeding is defined as an infant receiving only breast milk and no other liquids or solids except for drops or syrups consisting of vitamins, minerals, or medicines. In 2007, Healthy People 2010 (HP2010) objectives for breastfeeding initiation and duration were updated to include two new objectives on exclusive breastfeeding (i.e., to increase the proportion of mothers who exclusively breastfeed their infants through age 3 months to 60% and through age 6 months to 25% [objectives 16-19d and 16-19e]). To monitor progress toward achieving HP2010 breastfeeding objectives, CDC analyzed data from the National Immunization Survey (NIS). This report describes the results of that analysis, which indicated that rates for breastfeeding initiation and duration increased among infants born during 2000-2004. Rates for exclusive breastfeeding through ages 3 months and 6 months among infants born in 2004 were 30.5% and 11.3%, respectively, below targets set by HP2010. Rates of exclusive breastfeeding were significantly lower among black infants (compared with white infants) and infants born to unmarried mothers (compared with married mothers). Additionally, older age, urban residence, higher education, and higher income of mothers all were positively associated with exclusive breastfeeding. Further research is needed to identify successful programs and policies to support exclusive breastfeeding, especially among subgroups with the lowest rates.

  7. INFORMATION ASYMMETRY AND HERDING BEHAVIOR

    Full Text Available Conceptually, the stock market is strong form efficient in the long term. However, in practice, there are various forms of market anomalies that undermine the accuracy of the efficient market hypothesis. One factor suspected as the cause of market inefficiency is herding behavior. Investors herd when they imitate the actions of other investors. This behavior occurs when there is a continuous interaction among rational investors that prevents them from seeking information about market fundamentals. This study provides new insights by including information asymmetry as a moderating variable. This research examines the phenomenon of herding behavior in the Indonesia Stock Exchange as well as examines directly the effect of information asymmetry on herding behavior. The period of study is 2008 using time series of daily stocks data that actively traded in the capital market. Results of this study find that investor tends to follow market consensus when price changes at the low level, but when there is large price swing market participant acts independently from other investors. Interestingly, this study finds that information asymmetry is a necessary condition for the existence of herding behavior.

    Full Text Available Purpose: This article informs readers about the theoretical and practical origins of the behaviorally informed interventions (BIPI, analyzes examples of the BIPI from different policy sectors and strategies they offer for policy and regulatory design, and discusses applications and implications of BIPI for public interventions Methodology: This paper is based on a review of literature, as well as an inspection of administrative practices in OECD countries. It encompasses a systematic analysis of scientific papers fromthe SCOPUS database and a query carried out at the library of George Washington University. Findings: The traditional approach to public policy research is based on rational choice theory. It offers limited support, because by assuming perfect rationality of policy decisions, it overlooks existence of systematic errors and biases of human decision-making. The authors argue that behaviorally informed public interventions (BIPI might contribute to improving the effectiveness of a number of public measures – regulation, projects, programs, and even entire policies. Practical implications: The behavioral approach allows decision-makers to better understand the decisions and behaviors of citizens, as well as to design more effective interventions with minimum effort by adapting the existing solutions to real decision mechanisms of citizens. Originality: By combining the concepts of traditional approach with the growing behavioral approach, the authors aim to propose a new theoretical framework (BIPI to be used as a tool for policy design, delivery and evaluation.

    Systemic lupus erythematosus (SLE) and lupus nephritis (LN) disproportionately affect individuals who are members of racial/ethnic minority groups and individuals of lower socioeconomic status (SES). This study was undertaken to investigate the epidemiology and sociodemographics of SLE and LN in the low-income US Medicaid population. We utilized Medicaid Analytic eXtract data, with billing claims from 47 states and Washington, DC, for 23.9 million individuals ages 18-65 years who were enrolled in Medicaid for >3 months in 2000-2004. Individuals with SLE (≥3 visits >30 days apart with an International Classification of Diseases, Ninth Revision [ICD-9] code of 710.0) and with LN (≥2 visits with an ICD-9 code for glomerulonephritis, proteinuria, or renal failure) were identified. We calculated SLE and LN prevalence and incidence, stratified by sociodemographic category, and adjusted for number of American College of Rheumatology (ACR) member rheumatologists in the state and SES using a validated composite of US Census variables. We identified 34,339 individuals with SLE (prevalence 143.7 per 100,000) and 7,388 (21.5%) with LN (prevalence 30.9 per 100,000). SLE prevalence was 6 times higher among women, nearly double in African American compared to white women, and highest in the US South. LN prevalence was higher among all racial/ethnic minority groups compared to whites. The areas with lowest SES had the highest prevalence; areas with the fewest ACR rheumatologists had the lowest prevalence. SLE incidence was 23.2 per 100,000 person-years and LN incidence was 6.9 per 100,000 person-years, with similar sociodemographic trends. In this nationwide Medicaid population, there was sociodemographic variation in SLE and LN prevalence and incidence. Understanding the increased burden of SLE and its complications in this low-income population has implications for resource allocation and access to subspecialty care.

    In the years 2000-2004, reed canary grass (RCG) has been cultivated, harvested, stored, upgraded, and combusted at Umeaa Biofuel Technology Center (BTC), SLU Roebaecksdalen, Umeaa. The entire chain from the field to hot water has been handled by personnel at BTC. Data and experiences from the different handling stages have been continuously collected. In this time period, RCG has been harvested each spring. The mean harvest level on SLU properties has been approximately 4 ton DM/ha and the dry matter content at harvest has been on average 11-12 %. Winter and harvest losses has been determined to approximately 44 %, by a comparison of harvest levels in spring and harvest levels in sample squares in late fall. An alternate method of cutting in late fall, where the crop is left in the field until spring, has been tested. With this method, the risk for cutting of green shoots is eliminated and the isolating effect of the cut ley is decreasing the frost depth in the field. Three different techniques of baling have been tested: large and small square baling, and round baling. Round baling is most suitable for the conditions at BTC, because of the low availability of large square baling equipment in the area. Otherwise large square baling is more time efficient. Thus, the low weight of round baling equipment is advantageous and gives rise to less ground damages. On BTC, the RCG bales are stored outside on an asphalt area, covered with ensilage plastic on a layer of pallets. This handling procedure is working satisfactory with relatively low material losses, but when larger quantities are stored inside storage is to prefer. The economy of RCG cultivation is, as for all agricultural crops, dependent of subsidies within EU's Common Agricultural Policy (CAP). Subsidies can be received for RCG cultivation on ordinary farmland and on fallow farmland. An extra energy crop subsidy can be received for RCG cultivation on ordinary farmland if the energy crop is utilised as

METHODS: Data were collected from computerized records of all children OBJETIVOS: Estimar la carga anual por diarrea y por diarrea asociada con la infección por rotavirus (RV en niños atendidos en clínicas y hospitales públicos de Honduras. MÉTODOS: Los datos se obtuvieron a partir de los registros computarizados de todos los niños menores de 5 años atendidos por diarrea en clínicas y hospitales operados por la Secretaría de Salud de Honduras durante el período 2000-2004. Una revisión de los estudios realizados sobre RV en Honduras y los países vecinos ofreció estimados de las tasas de detección de RV en niños tratados por diarrea aguda hospitalizados o de forma ambulatoria. Con estos datos se estimó el número anual de casos de diarrea y de diarrea asociada con la infección por RV en Honduras, la incidencia acumulativa de diarrea y de diarrea asociada con la infección por RV en niños menores de 5 años y el número de muertes debido a RV en niños hospitalizados por diarrea. RESULTADOS: Entre los años 2000 y 2004 se registraron medias anuales de 222 000 visitas médicas, 4 390 hospitalizaciones y 162 muertes hospitalarias por diarrea en niños menores de 5 años en instalaciones sanitarias públicas de Honduras. A partir de la revisión de la literatura científica relativa a Honduras y los países vecinos se estimó que 30% de los casos de diarrea atendidos ambulatoriamente y 43% de los hospitalizados podrían deberse a RV. En consecuencia, se estimó que 66 600 visitas médicas ambulatorias, 1 888 hospitalizaciones y 70 muertes hospitalarias de niños menores de 5 años pueden atribuirse a la infección por RV anualmente en Honduras. Por lo tanto, los riesgos de un niño en sus primeros 5 años de vida de asistir a una consulta, de ser

  13. Inform: Efficient Information-Theoretic Analysis of Collective Behaviors

    2018-06-01

    Full Text Available The study of collective behavior has traditionally relied on a variety of different methodological tools ranging from more theoretical methods such as population or game-theoretic models to empirical ones like Monte Carlo or multi-agent simulations. An approach that is increasingly being explored is the use of information theory as a methodological framework to study the flow of information and the statistical properties of collectives of interacting agents. While a few general purpose toolkits exist, most of the existing software for information theoretic analysis of collective systems is limited in scope. We introduce Inform, an open-source framework for efficient information theoretic analysis that exploits the computational power of a C library while simplifying its use through a variety of wrappers for common higher-level scripting languages. We focus on two such wrappers here: PyInform (Python and rinform (R. Inform and its wrappers are cross-platform and general-purpose. They include classical information-theoretic measures, measures of information dynamics and information-based methods to study the statistical behavior of collective systems, and expose a lower-level API that allow users to construct measures of their own. We describe the architecture of the Inform framework, study its computational efficiency and use it to analyze three different case studies of collective behavior: biochemical information storage in regenerating planaria, nest-site selection in the ant Temnothorax rugatulus, and collective decision making in multi-agent simulations.

    Full Text Available How has human information behavior evolved? Our paper explores this question in the form of notions, models and theories about the relationship between information behavior and human evolution. Alexander's Ecological Dominance and Social Competition/Cooperation (EDSC model currently provides the most comprehensive overview of human traits in the development of a theory of human evolution and sociality. His model provides a basis for explaining the evolution of human socio-cognitive abilities, including ecological dominance, and social competition/cooperation. Our paper examines the human trait of information behavior as a socio-cognitive ability related to ecological dominance, and social competition/cooperation. The paper first outlines what is meant by information behavior from various interdisciplinary perspectives. We propose that information behavior is a socio-cognitive ability that is related to and enables other socio-cognitive abilities such as human ecological dominance, and social competition/cooperation. The paper reviews the current state of evolutionary approaches to information behavior and future directions for this research

    The aim of this study was to investigate the rate at which abstracts orally presented at the ESGAR 2000 and 2001 meetings were published between 2000-2004, and to identify predictive factors of publication. The abstracts of ESGAR meeting presentations were reviewed and classified according to organ, modality, type of design, country of origin of the studies and basic categories of diagnostic or interventional. The presentations were searched for publication in Medline-indexed journals using the PubMed server. The publication rates of the presentations, the time period between the presentation and publication, and the journal in which the article had appeared were investigated. An overall number of 109 publications were found originating from 276 presentations (39.5%). The median and inter-quartile range [IQR] between the abstract presentation and subsequently full publication was 18 months [1.0 -53.0]. The journal with the highest number of derived articles from abstract presentation was European Radiology (n=21, 19.2%). Retrospective studies were found to be more frequently published than prospective studies (p=0.001). The publication rate did not show any statistically significant difference between groups of other classifications. The publication rate of studies orally presented at ESGAR meetings was 39.5%. No specific variable other than the type of design of the studies appeared to influence the publication rate. (orig.)

    femenino, residentes en la región Norte y Noreste y sin transplante renal presentan mayor riesgo de muerte.OBJECTIVE: To describe the clinical and epidemiological profile of patients under renal replacement therapies, identifying risk factors for death. METHODS: This is a non-concurrent cohort study of data for 90,356 patients in the National Renal Replacement Therapies Database. A deterministic-probabilistic linkage was performed using the Authorization System for High Complexity/Cost Procedures and the Mortality Information System databases. All patients who started dialysis between 1/1/2000 and 12/31/2004 were included and followed until death or the end of 2004. Age, sex, region of residence, primary renal disease and causes of death were analyzed. A proportional hazards model was used to identify factors associated with risk of death. RESULTS: The prevalence of patients under renal replacement therapies increased an average of 5.5%, while incidence remained stable during the period. Hemodialysis was the predominant initial modality (89%. The patients were majority male with mean age 53 years, residents of the Southeast region and presented unknown causes as the main cause of chronic renal disease, followed by hypertension, diabetes and glomerulonephritis. Of these patients, 42% progressed to death and 7% underwent kidney transplantation. The patients on peritoneal dialysis were older and had higher prevalence of diabetes. The death rate varied from 7% among transplanted patients to 45% among non-transplanted patients. In the final Cox proportional hazards model, the risk of mortality was associated with increasing age, female sex, having diabetes, living in the North and Northeast region, peritoneal dialysis as a first modality and not having renal transplantation. CONCLUSIONS: There was an increased prevalence of patients on renal therapy in Brazil. Increased risk of death was associated with advanced age, diabetes, the female sex, residents of the North and

    Full Text Available The paper deals with creation of integrated information system architecture capable of supporting management decisions using behavioral features. The paper considers the architecture of information decision support system for production system management. The behavioral feature is given to an information system, and it ensures extraction, processing of information, management decision-making with both automated and automatic modes of decision-making subsystem being permitted. Practical implementation of information system with behavior is based on service-oriented architecture: there is a set of independent services in the information system that provides data of its subsystems or data processing by separate application under the chosen variant of the problematic situation settlement. For creation of integrated information system with behavior we propose architecture including the following subsystems: data bus, subsystem for interaction with the integrated applications based on metadata, business process management subsystem, subsystem for the current state analysis of the enterprise and management decision-making, behavior training subsystem. For each problematic situation a separate logical layer service is created in Unified Service Bus handling problematic situations. This architecture reduces system information complexity due to the fact that with a constant amount of system elements the number of links decreases, since each layer provides communication center of responsibility for the resource with the services of corresponding applications. If a similar problematic situation occurs, its resolution is automatically removed from problem situation metamodel repository and business process metamodel of its settlement. In the business process performance commands are generated to the corresponding centers of responsibility to settle a problematic situation.

    Despite Coronary Heart Disease exacting a heavy toll among Aboriginal Australians, accurate estimates of its epidemiology are limited. This study compared the incidence of acute myocardial infarction (AMI) and 28-day case fatality (CF) among Aboriginal and non-Aboriginal Western Australians aged 25-74 years from 2000-2004. Incident (AMI hospital admission-free for 15 years) AMI events and 28-day CF were estimated using person-based linked hospital and mortality data. Age-standardised incidence rates and case fatality percentages were calculated by Aboriginality and sex. Of 740 Aboriginal and 6933 non-Aboriginal incident events, 208 and 2352 died within 28 days, respectively. The Aboriginal age-specific incidence rates were 27 (males) and 35 (females) times higher than non-Aboriginal rates in the 25-29 year age group, decreasing to 2-3 at 70-74 years. The male:female age-standardised incidence rate ratio was 2.2 in Aboriginal people 25-54 years compared with 4.5 in non-Aboriginal people. Aboriginal age-standardised CF percentages were 1.4 (males) and 1.1 (females) times higher at age 25-54 years and 1.5 times higher at age 55-74 years. These data suggest higher CF and, more importantly, AMI incidence contribute to the excess ischaemic heart disease mortality in Aboriginal Western Australians. The poorer cardiovascular health in Aboriginal women, particularly in younger age groups, should be investigated.

    Full Text Available The aim of this study was to investigate media literacy and information behavior in cyberspace. This was a review and library research based study. With the advent of the digital age and the increasing spread of the World Wide Web, popularity and general acceptance of virtual social networks in the world today, the need to examine media literacy and information behavior in human life is important. Approach to media literacy which is the subset of information literacy in cyberspace has become necessary and obvious. As an individual, higher level of literacy can lead to choosing better content and search for information to find useful content. By assessing the theoretical basis and different approaches in a virtual environment, it can be concluded that having literacy skills and information behavior, the period of time spent in cyberspace and the number of readers have increased, leading to the ability to criticize and interpret the social, political and economic information and identify useful information. Consequently, by acquiring new technologies and increasing the adaptability in viewpoints and improving skills within researchers, the context for developing new ideas will be provided.

    Considering the fact, in the real world, that information is transmitted with a time delay, we study an evolutionary spatial prisoner's dilemma game where agents update strategies according to certain information that they have learned. In our study, the game dynamics are classified by the modes of information learning as well as game interaction, and four different combinations, i.e. the mean-field case, case I, case II and local case, are studied comparatively. It is found that the time delay in case II smoothes the phase transition from the absorbing states of C (or D) to their mixing state, and promotes cooperation for most parameter values. Our work provides insights into the temporal behavior of information and the memory of the system, and may be helpful in understanding the cooperative behavior induced by the time delay in social and biological systems.

Se determinaron la tendencia, los coeficientes estacionales de la serie de casos, las tasas de incidencia en función de la edad, el sexo y el año de declaración y las razones de tasas. Resultados: Se observó una tendencia descendente en la declaración de casos durante el periodo de estudio y se detectó un coeficiente estacional significativo en la cuatrisemana seis (c=12,854, p=0,023. La tasa de incidencia fue mayor en los menores de cinco años y en los hombres, ascendiendo a 1841,9 casos (IC 95: 1797,2-1889,6 y 99,7 casos (IC 95% 96,9-102,4 por 100.000 habitantes-año respectivamente. Conclusiones: La infección por Campylobacter tiene lugar en mayor medida en la época del final de la primavera, afectando principalmente a los niños. Es necesario profundizar en el conocimiento de la epidemiología de este microorganismo a nivel local con un abordaje multidisciplinar que considere tanto aspectos microbiológicos como epidemiológicos.

    Full Text Available In the last few years, a new type of synchronous social networking services (SNSs has emerged—social live streaming services (SLSSs. Studying SLSSs is a new and exciting research field in information science. What information behaviors do users of live streaming platforms exhibit? In our empirical study we analyzed information production behavior (i.e., broadcasting as well as information reception behavior (watching streams and commenting on them. We conducted two quantitative investigations, namely an online survey with YouNow users (N = 123 and observations of live streams on YouNow (N = 434. YouNow is a service with video streams mostly made by adolescents for adolescents. YouNow users like to watch streams, to chat while watching, and to reward performers by using emoticons. While broadcasting, there is no anonymity (as in nearly all other WWW services. Synchronous SNSs remind us of the film The Truman Show, as anyone has the chance to consciously broadcast his or her own life real-time.

    Full Text Available Computer services are normally assumed to work well all the time. This usually happens for crucial services like bank electronic services, but not necessarily so for others, that there is no commercial interest in their operation. In this work we examined the operation and the errors of information services and tried to find clues that will help predicting the consistency of the behavior and the quality of the harvesting, which is harder because of the transient conditions and the many services and the huge amount of harvested information. We found many unexpected situations. The services that always successfully satisfy a request may in fact return part of it. A significant part of the OAI services have ceased working while many other serves occasionally fail to respond. Some services fail in the same way each time, and we pronounce them dead, as we do not see a way to overcome that. Others also always, or sometimes fail, but not in the same way, and we hope that their behavior is affected by temporary factors, that may improve later on. We categorized the services into classes, to study their behavior in more detail.

    In the information-based economy, information literacy has become the foundation of scientific literacy, and provides the basis for innovative growth. Exploring the relationship between information-seeking behaviors and innovative behaviors of nursing students could help guide the development of information literacy education and training for nursing students. The relationship between information-seeking behavior and innovative behavior in nursing students has received little attention, however. This study aims to explore the relationship between information-seeking behavior and innovative behavior of nursing students. Nursing students in Xiangya Medical School, Central South University and Medical School of Hunan Normal University in the Chinese Province of Hunan were surveyed with an information-seeking behavior scale and an innovative behavior scale. A total of 1247 nursing students were included in the final analysis. The results showed that both information-seeking behavior and innovative behavior were significantly better in undergraduates than in junior college nursing students (P information-seeking behavior was positively related to innovative behavior (r = 0.63, P information-seeking behavior were also correlated with innovative behavior in varying degrees. Furthermore, information utilization was proved to be the strongest predictor of innovative behavior. Information-seeking behavior is positively associated with innovative behavior among nursing students. There is a need to integrate information literacy education with information retrieval courses, especially in the aspects of information utilization, retrieval, and assessment.

    Branch, Marc N

    2006-05-01

    Behavioral pharmacology is a maturing science that has made significant contributions to the study of drug effects on behavior, especially in the domain of drug-behavior interactions. Less appreciated is that research in behavioral pharmacology can have, and has had, implications for the experimental analysis of behavior, especially its conceptualizations and theory. In this article, I outline three general strategies in behavioral pharmacology research that have been employed to increase understanding of behavioral processes. Examples are provided of the general characteristics of the strategies and of implications of previous research for behavior theory. Behavior analysis will advance as its theories are challenged.

    2015-05-01

    The present paper analyzes consistencies between the philosophical systems of David Hume and B. F. Skinner, focusing on their conceptualization of causality and attitudes about scientific behavior. The ideas that Hume initially advanced were further developed in Skinner's writings and shaped the behavior-analytic approach to scientific behavior. Tracing Skinner's logical antecedents allows for additional historical and philosophical clarity when examining the development of radical behaviorism.

  15. Explicit information reduces discounting behavior in monkeys

    Directory of Open Access Journals (Sweden)

    John ePearson

    2010-12-01

    Full Text Available Animals are notoriously impulsive in common laboratory experiments, preferring smaller, sooner rewards to larger, delayed rewards even when this reduces average reward rates. By contrast, the same animals often engage in natural behaviors that require extreme patience, such as food caching, stalking prey, and traveling long distances to high quality food sites. One possible explanation for this discrepancy is that standard laboratory delay discounting tasks artificially inflate impulsivity by subverting animals’ common learning strategies. To test this idea, we examined choices made by rhesus macaques in two variants of a standard delay discounting task. In the conventional variant, post-reward delays were uncued and adjusted to render total trial length constant; in the second, all delays were cued explicitly. We found that measured discounting was significantly reduced in the cued task, with discount rates well below those reported in studies using the standard uncued design. When monkeys had complete information, their decisions were more consistent with a strategy of reward rate maximization. These results indicate that monkeys, and perhaps other animals, are more patient than is normally assumed, and that laboratory measures of delay discounting may overstate impulsivity.

    2008-06-01

    After having identified that the public trust towards the regulators could be very different from one country to another even though they are neighbours, the NEA Committee on Nuclear Regulatory Activities (CNRA) has developed an activity in public communication and three successful international workshops have been held during this last decade: 1. Paris, December 2000 - Investing in Trust: Nuclear Regulators and the Public; 2. Ottawa, May 2004 - Building, Measuring and Improving Public Confidence; 3. Tokyo, May 2007 - Transparency of Nuclear Regulatory Activities. Collectively these workshops have illustrated valuable feedback experience can be exchanged amongst countries. The objective of this report is to: - summarise the lessons learned from the three CNRA workshops on public communication and related CNRA/WGPC activities over the past decade, - assess their influence on the developments of the different countries' approaches in public communication, - propose a way forward for future work. Over the last two decades public perception of nuclear in some countries has changed substantially and there is an increasing public thirst for information. This, coupled with the generalisation of Freedom of Information Acts in OECD countries and new transparency laws, has resulted in Nuclear Regulatory Organisations (NROs) turning their attention to activities which inform and engage the public. Acts related to the freedom of information (FOI), which give the public the right of access to all types of recorded information, are in force in all OECD countries since 2006 and in some countries they have been supplemented by specific Acts highlighting the importance of Nuclear Regulatory transparency and providing for its implementation. Public expectations regarding the Nuclear Regulatory Organisations (NRO) have significantly increased in every country during the last 20 years and in turn the communication of most NROs has tremendously developed its activities toward informing

    The decision to gather information should take into account both the value of information and its accrual costs in time, energy and money. Here we explore how people balance the monetary costs and benefits of gathering additional information in a perceptual-motor estimation task. Participants were rewarded for touching a hidden circular target on a touch-screen display. The target’s center coincided with the mean of a circular Gaussian distribution from which participants could sample repeatedly. Each “cue” — sampled one at a time — was plotted as a dot on the display. Participants had to repeatedly decide, after sampling each cue, whether to stop sampling and attempt to touch the hidden target or continue sampling. Each additional cue increased the participants’ probability of successfully touching the hidden target but reduced their potential reward. Two experimental conditions differed in the initial reward associated with touching the hidden target and the fixed cost per cue. For each condition we computed the optimal number of cues that participants should sample, before taking action, to maximize expected gain. Contrary to recent claims that people gather less information than they objectively should before taking action, we found that participants over-sampled in one experimental condition, and did not significantly under- or over-sample in the other. Additionally, while the ideal observer model ignores the current sample dispersion, we found that participants used it to decide whether to stop sampling and take action or continue sampling, a possible consequence of imperfect learning of the underlying population dispersion across trials.

    Multitasking information behavior involves multiple forms of information searching such as library and Web search. Few researchers, however, have explored multitasking information behavior and information task switching in libraries in conjunction with psychological variables. This study explored this behavior in terms of anxiety under time pressure. This was an exploratory case study. Participant searched information for three unrelated everyday life information topics during a library visit, in a timeframe of one hour. The data collection tools used were: diary, observation, interview, and the State-Trait Anxiety Inventory test. Participant took the Trait-anxiety test before the library visit to measure anxiety level as a personal characteristic. She also took State-anxiety test before, during and after the library visit to measure anxiety levels regarding the information seeking behavior. The results suggested that participant had high levels of anxiety at the beginning of the multitasking information behavior. The reason for that was the concern about the performance as well as the identification of the right resources. During the multitasking information behavior, participant still had anxiety to find the right information. The levels of anxiety, however, were less due to library’s good organized structure. At the end of the information seeking process, the levels of anxiety dropped significant and therefore calm and safety returned. Finally, participant searched information for topics that were more important and for which she had prior knowledge When people, under time pressure, have access to well organized information, the levels of anxiety might decrease

Relevant literature was reviewed for framing the research questions and designing the questionnaire items for survey. Survey subjects were students from an university at northern Taiwan. A set of questionnaire items were used to collect research data. Statistical analysis from 252 valid data reveals some items were highly rated: Students reflected highly for their need of knowledge under the security threat of personal information (M = 4.29. They reacted strongly on acquiring knowledge and resources through the Internet (M = 4.24. They preferred the use of resources clear and easy to be understood (M = 4.04. However, most students had low level faith toward either government or non-governmental organizations in securing their personal information (M < 3.0 for most items. More effort among education and government should be emphasized in the future to improve personal use and reduce uncertainty in the use of personal information.

Moreover, analysis of the temporal trends in exposure histories of the individuals/groups play an important role in assessing the need of improved standards of protection and the impact of implementation of such measures. The paper presents the analysis of annual effective dose and collective dose to the radiation workers, which are indicators of individual risk and the impact of the practice. The present study also gives the analysis of the effective dose, cumulative dose and various dose distribution ratios (SR E and NR E ) for the block of 5 years (2000-2004) of RAPS 1 and 2 the oldest PHWR in the country and RAPS 3 and 4 the latest in the series incorporating many improvements in design and operation. It is seen that occupational exposures at NPPs have been showing a steadily decreasing trend, which is a result of a number of design improvements, operation and protection measures. However, to achieve world standards, we have to go a long way by further carrying out identification of areas of improvement, good operating practices along with the desired modifications in design.

    1999-11-01

    In this first Institutional Plan prepared by Bechtel BWXT Idaho, LLC, for the Idaho National Engineering and Environmental Laboratory, the INEEL will focus it's efforts on three strategic thrusts; (1) Environmental Management stewardship for DOE-EM, (2) Nuclear reactor technology for DOE-Nuclear Energy (NE), and (3) Energy R&D, demonstration, and deployment (initial focus on biofuels and chemical from biomass). The first strategic thrust focuses on meeting DOE-EM's environmental cleanup and long-term stewardship needs in a manner that is safe, cost-effective, science-based, and approved by key stakeholders. The science base at the INEEL will be further used to address a grand challenge for the INEEL and the DOE complex - the development of a fundamental scientific understanding of the migration of subsurface contaminants. The second strategic thrust is directed at DOE-NE's needs for safe, economical, waste-minimized, and proliferation-resistant nuclear technologies. As NE lead laboratories, the INEEL and ANL will pursue specific priorities. The third strategic thrust focuses on DOE's needs for clean, efficient, and renewable energy technology. As an initial effort, the INEEL will enhance its capability in biofuels, bioprocessing, and biochemicals. The content of this Institutional Plan is designed to meet basic DOE requirements for content and structure and reflect the key INEEL strategic thrusts. Updates to this Institutional Plan will offer additional content and resource refinements.

    The wealth of information available on seemingly every topic creates a considerable challenge both for information providers trying to rise above the noise and discerning individuals trying to find relevant, trustworthy information. We approach this information problem by investigating how passive versus interactive information interventions can impact the antecedents of behavior change using the context of solar energy adoption, where persistent information gaps are known to reduce market potential. We use two experiments to investigate the impact of both passive and interactive approaches to information delivery on the antecedents (attitudes, subjective norms, and perceived behavioral control in the Theory of Planned Behavior) of intentions and behavior, as well as their effect on intentions and behavior directly. The passive information randomized control trial delivered via Amazon Mechanical Turk tests the effectiveness of delivering the same content in a single message versus multiple shorter messages. The interactive information delivery uses an online (mobile and PC) trivia-style gamification platform. Both experiments use the same content and are carried out over a two-week time period. Our findings suggest that interactive, gamified information has greater impact than passive information, and that shorter multiple messages of passive information are more effective than a single passive message.

    2015-05-01

    Full Text Available This paper deals with the information behavior as support for models of communication design in the areas of Information Science, Library and Music. The communication models proposition is based on models of Tubbs and Moss (2003, Garvey and Griffith (1972, adapted by Hurd (1996 and Wilson (1999. Therefore, the questions arose: (i what are the informational skills required of librarians who act as mediators in scholarly communication process and informational user behavior in the educational environment?; (ii what are the needs of music related researchers and as produce, seek, use and access the scientific knowledge of your area?; and (iii as the contexts involved in scientific collaboration processes influence in the scientific production of information science field in Brazil? The article includes a literature review on the information behavior and its insertion in scientific communication considering the influence of context and/or situation of the objects involved in motivating issues. The hypothesis is that the user information behavior in different contexts and situations influence the definition of a scientific communication model. Finally, it is concluded that the same concept or a set of concepts can be used in different perspectives, reaching up, thus, different results.

  6. Information Processing Features Can Detect Behavioral Regimes of Dynamical Systems

    Directory of Open Access Journals (Sweden)

    2018-01-01

    Full Text Available In dynamical systems, local interactions between dynamical units generate correlations which are stored and transmitted throughout the system, generating the macroscopic behavior. However a framework to quantify exactly how these correlations are stored, transmitted, and combined at the microscopic scale is missing. Here we propose to characterize the notion of “information processing” based on all possible Shannon mutual information quantities between a future state and all possible sets of initial states. We apply it to the 256 elementary cellular automata (ECA, which are the simplest possible dynamical systems exhibiting behaviors ranging from simple to complex. Our main finding is that only a few information features are needed for full predictability of the systemic behavior and that the “information synergy” feature is always most predictive. Finally we apply the idea to foreign exchange (FX and interest-rate swap (IRS time-series data. We find an effective “slowing down” leading indicator in all three markets for the 2008 financial crisis when applied to the information features, as opposed to using the data itself directly. Our work suggests that the proposed characterization of the local information processing of units may be a promising direction for predicting emergent systemic behaviors.

    Patients are increasingly using the Internet and other technologies to engage in their own healthcare, but little research has focused on the determinants of consumer eHealth behaviors related to Internet use. This study uses data from 115,089 respondents to four years of the National Health Interview Series to identify the associations between one consumer eHealth behavior (information seeking) and demographics, health measures, and Personal Health Information Management (PHIM) (messaging, scheduling, refills, and chat). Individuals who use PHIM are 7.5 times more likely to search the internet for health related information. Just as health has social determinants, the results of this study indicate there are potential social determinants of consumer eHealth behaviors including personal demographics, health status, and healthcare access.

    This Review summarizes and draws connections between diverse streams of empirical research on privacy behavior. We use three themes to connect insights from social and behavioral sciences: people's uncertainty about the consequences of privacy-related behaviors and their own preferences over those consequences; the context-dependence of people's concern, or lack thereof, about privacy; and the degree to which privacy concerns are malleable—manipulable by commercial and governmental interests. Organizing our discussion by these themes, we offer observations concerning the role of public policy in the protection of privacy in the information age.

  9. Information driven self-organization of complex robotic behaviors.

    Directory of Open Access Journals (Sweden)

    Georg Martius

    Full Text Available Information theory is a powerful tool to express principles to drive autonomous systems because it is domain invariant and allows for an intuitive interpretation. This paper studies the use of the predictive information (PI, also called excess entropy or effective measure complexity, of the sensorimotor process as a driving force to generate behavior. We study nonlinear and nonstationary systems and introduce the time-local predicting information (TiPI which allows us to derive exact results together with explicit update rules for the parameters of the controller in the dynamical systems framework. In this way the information principle, formulated at the level of behavior, is translated to the dynamics of the synapses. We underpin our results with a number of case studies with high-dimensional robotic systems. We show the spontaneous cooperativity in a complex physical system with decentralized control. Moreover, a jointly controlled humanoid robot develops a high behavioral variety depending on its physics and the environment it is dynamically embedded into. The behavior can be decomposed into a succession of low-dimensional modes that increasingly explore the behavior space. This is a promising way to avoid the curse of dimensionality which hinders learning systems to scale well.

    Eger, M S; Godkin, R L; Valentine, S R

    2001-01-01

    Studies report physician resistance to information technology in a time when the practice of medicine could benefit from technological support. Anecdotally, it is suspected that lack of training, discomfort with technological innovations, a perceived shift in the doctor/patient relationship, or medical/legal issues may account for this circumstance. Empirical studies attribute this lag to age, personality factors, behavioral issues, and occupational influences. This paper integrates the information technology and consumer behavior literatures to discuss physicians' acceptance, adoption, and application of IT.

    2014-01-01

    Full Text Available The authors found the behavioral factors that influence the organization members’ compliance with the information security policy in organizations on the basis of neutralization theory, Theory of planned behavior, and protection motivation theory. Depending on the theory of planned behavior, members’ attitudes towards compliance, as well as normative belief and self-efficacy, were believed to determine the intention to comply with the information security policy. Neutralization theory, a prominent theory in criminology, could be expected to provide the explanation for information system security policy violations. Based on the protection motivation theory, it was inferred that the expected efficacy could have an impact on intentions of compliance. By the above logical reasoning, the integrative behavioral model and eight hypotheses could be derived. Data were collected by conducting a survey; 194 out of 207 questionnaires were available. The test of the causal model was conducted by PLS. The reliability, validity, and model fit were found to be statistically significant. The results of the hypotheses tests showed that seven of the eight hypotheses were acceptable. The theoretical implications of this study are as follows: (1 the study is expected to play a role of the baseline for future research about organization members’ compliance with the information security policy, (2 the study attempted an interdisciplinary approach by combining psychology and information system security research, and (3 the study suggested concrete operational definitions of influencing factors for information security policy compliance through a comprehensive theoretical review.

    2012-05-01

    Reputation systems promote cooperation and deter antisocial behavior in groups. Little is known, however, about how and why people share reputational information. Here, we seek to establish the existence and dynamics of prosocial gossip, the sharing of negative evaluative information about a target in a way that protects others from antisocial or exploitative behavior. We present a model of prosocial gossip and the results of 4 studies testing the model's claims. Results of Studies 1 through 3 demonstrate that (a) individuals who observe an antisocial act experience negative affect and are compelled to share information about the antisocial actor with a potentially vulnerable person, (b) sharing such information reduces negative affect created by observing the antisocial behavior, and (c) individuals possessing more prosocial orientations are the most motivated to engage in such gossip, even at a personal cost, and exhibit the greatest reduction in negative affect as a result. Study 4 demonstrates that prosocial gossip can effectively deter selfishness and promote cooperation. Taken together these results highlight the roles of prosocial motivations and negative affective reactions to injustice in maintaining reputational information sharing in groups. We conclude by discussing implications for reputational theories of the maintenance of cooperation in human groups.

    Frameworks are needed to inform diabetes self-care programs for diverse populations. We tested the Information-Motivation-Behavioral Skills (IMB) model in a sample of Puerto Ricans with Type 2 diabetes (N = 118). Structural equation models evaluated model fit and interrelations between IMB constructs. For diet behavior, information and motivation related to behavioral skills ( r = 0.19, p motivation related to behavioral skills (r = 0.53, p < .001), and behavioral skills related to behavior (r = 0.45, p < .001). The IMB model could inform interventions targeting these behaviors in diabetes.

    When individual animals make decisions, they routinely use information produced intentionally or unintentionally by other individuals. Despite its prevalence and established fitness consequences, the effects of such social information on ecological dynamics remain poorly understood. Here, we synthesize results from ecology, evolutionary biology, and animal behavior to show how the use of social information can profoundly influence the dynamics of populations and communities. We combine recent theoretical and empirical results and introduce simple population models to illustrate how social information use can drive positive density-dependent growth of populations and communities (Allee effects). Furthermore, social information can shift the nature and strength of species interactions, change the outcome of competition, and potentially increase extinction risk in harvested populations and communities.

    2018-01-10

    Umbilical cord blood is a source of hematopoietic stem cells essential to treat life-threatening diseases, such as leukemia and lymphoma. However, only a very small percentage of parents donate upon delivery. The decision to donate the cord blood occurs at a very specific time and when parents likely experience emotional, informational, and decisional overloads; these features of cord blood donation make it different from other pro-social activities. In collaboration with an OB-GYN clinic in Milan, Italy, we conducted the first randomized controlled trial that applies tools from behavioral science to foster cord blood donation, and quantified the gains that informational and behavioral "nudges" can achieve. We found that information and "soft" commitments increased donations; approaching expecting parents closer to the delivery date and providing them with multiple reminders, moreover, had the strongest impact. However, a significant portion of women who expressed consent to donate could not do so because of organizational constraints. We conclude that simple, non-invasive behavioral interventions that address information gaps and procrastination, and that increase the salience of the activity can substantially enhance altruistic donations of cord blood, especially when coupled with organizational support.

    Bloss, Cinnamon S; Madlensky, Lisa; Schork, Nicholas J; Topol, Eric J

    2011-01-01

    Individuals can now obtain their personal genomic information via direct-to-consumer genetic testing, but what, if any, impact will this have on their lifestyle and health? A recent longitudinal cohort study of individuals who underwent consumer genome scanning found minimal impacts of testing on risk-reducing lifestyle behaviors, such as diet and exercise. These results raise an important question: is personal genomic information likely to beneficially impact public health through motivation of lifestyle behavioral change? In this article, we review the literature on lifestyle behavioral change in response to genetic testing for common disease susceptibility variants. We find that only a few studies have been carried out, and that those that have been done have yielded little evidence to suggest that the mere provision of genetic information alone results in widespread changes in lifestyle health behaviors. We suggest that further study of this issue is needed, in particular studies that examine response to multiplex testing for multiple genetic markers and conditions. This will be critical as we anticipate the wide availability of whole-genome sequencing and more comprehensive phenotyping of individuals. We also note that while simple communication of genomic information and disease susceptibility may be sufficient to catalyze lifestyle changes in some highly motivated groups of individuals, for others, additional strategies may be required to prompt changes, including more sophisticated means of risk communication (e.g., in the context of social norm feedback) either alone or in combination with other promising interventions (e.g., real-time wireless health monitoring devices).

  5. Procedural Information and Behavioral Control: Longitudinal Analysis of the Intention-Behavior Gap in the Context of Recycling

    Directory of Open Access Journals (Sweden)

    Sonny Rosenthal

    2018-01-01

    Full Text Available The theory of planned behavior states that individuals act on their intentions, especially when they have behavioral control. The current study examines how seeking recycling-related procedural information—i.e., information about how and where to recycle—is related to behavioral control. Hypothesis testing used hierarchical ordinary least squares regression analysis of longitudinal data from 553 survey respondents. Results supported seven hypotheses. Most notably, procedural information seeking both mediated and moderated the relationship between intention and behavior. Further, the moderation effect was itself mediated by behavioral control. The argument for this mediated moderation is that information seeking enhances behavioral control, and it is primarily behavioral control that moderates the relationship between intention and behavior. These results have implications for the theory of planned behavior and, more generally, for how individuals use information to support their behaviors.

  7. An information propagation model considering incomplete reading behavior in microblog

    Microblog is one of the most popular communication channels on the Internet, and has already become the third largest source of news and public opinions in China. Although researchers have studied the information propagation in microblog using the epidemic models, previous studies have not considered the incomplete reading behavior among microblog users. Therefore, the model cannot fit the real situations well. In this paper, we proposed an improved model entitled Microblog-Susceptible-Infected-Removed (Mb-SIR) for information propagation by explicitly considering the user's incomplete reading behavior. We also tested the effectiveness of the model using real data from Sina Microblog. We demonstrate that the new proposed model is more accurate in describing the information propagation in microblog. In addition, we also investigate the effects of the critical model parameters, e.g., reading rate, spreading rate, and removed rate through numerical simulations. The simulation results show that, compared with other parameters, reading rate plays the most influential role in the information propagation performance in microblog.

  8. Information spreading in Delay Tolerant Networks based on nodes' behaviors

    Science.gov (United States)

    Wu, Yahui; Deng, Su; Huang, Hongbin

    2014-07-01

    Information spreading in DTNs (Delay Tolerant Networks) adopts a store-carry-forward method, and nodes receive the message from others directly. However, it is hard to judge whether the information is safe in this communication mode. In this case, a node may observe other nodes' behaviors. At present, there is no theoretical model to describe the varying rule of the nodes' trusting level. In addition, due to the uncertainty of the connectivity in DTN, a node is hard to get the global state of the network. Therefore, a rational model about the node's trusting level should be a function of the node's own observing result. For example, if a node finds k nodes carrying a message, it may trust the information with probability p(k). This paper does not explore the real distribution of p(k), but instead presents a unifying theoretical framework to evaluate the performance of the information spreading in above case. This framework is an extension of the traditional SI (susceptible-infected) model, and is useful when p(k) conforms to any distribution. Simulations based on both synthetic and real motion traces show the accuracy of the framework. Finally, we explore the impact of the nodes' behaviors based on certain special distributions through numerical results.

    Preference for information is a personality trait that affects people's tendency to seek information in health-related situations. Prior studies have focused primarily on investigating its impact on patient-provider communication and on the implications for designing information interventions that prepare patients for medical procedures. Few studies have examined its impact on general consumers' interactions with Web-based search engines for health information or the implications for designing more effective health information search systems. This study intends to fill this gap by investigating the impact of preference for information on the search behavior of general consumers seeking health information, their perceptions of search tasks (representing information needs), and user experience with search systems. Forty general consumers who had previously searched for health information online participated in the study in our usability lab. Preference for information was measured using Miller's Monitor-Blunter Style Scale (MBSS) and the Krantz Health Opinion Survey-Information Scale (KHOS-I). Each participant completed four simulated health information search tasks: two look-up (fact-finding) and two exploratory. Their behaviors while interacting with the search systems were automatically logged and ratings of their perceptions of tasks and user experience with the systems were collected using Likert-scale questionnaires. The MBSS showed low reliability with the participants (Monitoring subscale: Cronbach alpha=.53; Blunting subscale: Cronbach alpha=.35). Thus, no further analyses were performed based on the scale. KHOS-I had sufficient reliability (Cronbach alpha=.77). Participants were classified into low- and high-preference groups based on their KHOS-I scores. The high-preference group submitted significantly shorter queries when completing the look-up tasks (P=.02). The high-preference group made a significantly higher percentage of parallel movements in query

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

    Full Text Available The purpose of this paper is to investigate the information needs and information seeking behavior of foreign students. A survey method was used for the undertaken study. The data were collected using a structured questionnaire, self-administered to 120 foreign students (60 males & 60 females with 88 (47 males & 41 females returns. The research is limited to post-graduate, M.Phil. and Ph.D. foreign students in University of Delhi. It was found that post-graduate students need information regarding their program of study while research scholars need information for writing research articles and for doing their research work. Most of them seek information through the internet. Research scholars used electronic resources such as databases, e-journals and e-theses and dissertations. 88.6% of the respondents also use books for seeking information. Their use of the library is limited with complaints about library staff and too few computer terminals. The present study will be helpful in designing new systems and services for the foreign students so that their information needs can be fulfilled easily. Further, findings of the study indicate that how the library professionals should assist foreign students to accomplish their information needs.

    2015-03-01

    A renaissance in the development of virtual (VR), augmented (AR), and mixed reality (MR) technologies with a focus on consumer and industrial applications is underway. As data becomes ubiquitous in our lives, a need arises to revisit the role of our bodies, explicitly in relation to data or information. Our observation is that VR/AR/MR technology development is a vision of the future framed in terms of promissory narratives. These narratives develop alongside the underlying enabling technologies and create new use contexts for virtual experiences. It is a vision rooted in the combination of responsive, interactive, dynamic, sharable data streams, and augmentation of the physical senses for capabilities beyond those normally humanly possible. In parallel to the varied definitions of information and approaches to elucidating information behavior, a myriad of definitions and methods of measuring and understanding presence in virtual experiences exist. These and other ideas will be tested by designers, developers and technology adopters as the broader ecology of head-worn devices for virtual experiences evolves in order to reap the full potential and benefits of these emerging technologies.

    Full Text Available Abstract Background Since the worldwide incidence of metabolic syndrome (Mets has rapidly increased, healthy behaviors such as weight control, engaging in physical activity, and healthy diet have been crucial in the management of Mets. The purpose of this study was to examine healthy behaviors practice and factors that affect the practice in relation to Mets on the basis of a modified Information-Motivation-Behavioral skills model (IMB with psychological distress, which is a well-known factor affecting healthy behaviors among individuals with Mets. Methods Study participants were 267 community dwelling adults (M age: 54.0 ± 8.1 years with Mets who were attending public health centers located in Seoul, South Korea. A structured questionnaire was administered in the areas of information, motivation, behavioral skills, and practice of Mets healthy behaviors and levels of psychological distress from May 2014 to September 2014. Structural equation modeling was used to test the modified IMB model. Results The modified IMB model had a good fit with the data, indicating that motivation and behavioral skills directly influenced the practice of Mets healthy behaviors, whereas information and psychological distress directly influenced motivation and influenced the practice of healthy behaviors through behavioral skills. These components of the modified IMB model explained 29.8 % of the variance in healthy behaviors for Mets. Conclusion Findings suggested that strengthening motivation and behavioral skills for healthy behaviors can directly enhance healthy behavior practice. Providing information about Mets related healthy behaviors and strategies for psychological distress management can be used as the first line evidence based intervention to systemically enhance motivation and behavioral skills among individuals with Mets.

    To identify the behavioral economics (BE) conceptual underpinnings of lifestyle financial incentive (FI) interventions. A mapping review of peer-reviewed literature was conducted by searching electronic databases. Inclusion criteria were real-world FI interventions explicitly mentioning BE, targeting individuals, or populations with lifestyle-related behavioral outcomes. Exclusion criteria were hypothetical studies, health professional focus, clinically oriented interventions. Study characteristics were tabulated according to purpose, categorization of BE concepts and FI types, design, outcome measures, study quality, and findings. Data Synthesis and Analysis: Financial incentives were categorized according to type and payment structure. Behavioral economics concepts explicitly used in the intervention design were grouped based on common patterns of thinking. The interplay between FI types, BE concepts, and outcome was assessed. Seventeen studies were identified from 1452 unique records. Analysis showed 76.5% (n = 13) of studies explicitly incorporated BE concepts. Six studies provided clear theoretical justification for the inclusion of BE. No pattern in the type of FI and BE concepts used was apparent. Not all FI interventions claiming BE inclusion did so. For interventions that explicitly included BE, the degree to which this was portrayed and woven into the design varied. This review identified BE concepts common to FI interventions, a first step in providing emergent and pragmatic information to public health and health promotion program planners.

    We investigated whether obtaining nutritional information influences reported changes in dietary behavior in cancer survivors and their relatives and whether nutritional information needs influence this association. We included 239 cancer survivors and their relatives, recruited from an online panel of cancer survivors and relatives. This panel completed a survey about their experiences with nutritional information provision by healthcare professionals and the media in the period after diagnosis, their information needs regarding nutrition and cancer, and whether they changed their dietary behavior since diagnosis. The survey showed that 56% of respondents obtained nutritional information, mostly during treatment. Respondents who obtained nutritional information more often reported to have altered their dietary behavior after diagnosis. This association was not altered by having information needs. The reported changes in dietary behavior were coherent with the recommendations of the World Cancer Research Fund: respondents reported to choose less products that promote weight gain, increased intake of plant foods, and decreased meat and alcohol use. Respondents who obtained nutritional information more often changed their dietary behavior, regardless whether they had nutritional information needs. This might be an indication that healthcare professionals should provide nutritional information not only to those expressing a need for nutritional information.

    2015-02-01

    Full Text Available As a basis for information recovery in open dynamic microeconomic systems, we emphasize the connection between adaptive intelligent behavior, causal entropy maximization and self-organized equilibrium seeking behavior. This entropy-based causal adaptive behavior framework permits the use of information-theoretic methods as a solution basis for the resulting pure and stochastic inverse economic-econometric problems. We cast the information recovery problem in the form of a binary network and suggest information-theoretic methods to recover estimates of the unknown binary behavioral parameters without explicitly sampling the configuration-arrangement of the sample space.

    2016-01-01

    SYNOPSIS Objective Parents’ poor monitoring of adolescents’ whereabouts and activities is commonly linked to adolescents’ increased engagement in delinquent behaviors. Yet, different domains of parental monitoring (parental monitoring behaviors vs. parental knowledge) and reports from multiple informants (parent vs. adolescent) may vary in their links to delinquent behavior. Design Seventy-four parental caregivers and 74 adolescents completed survey measures of parental monitoring and knowledge, and adolescents completed self-report surveys of delinquent behavior. Results We observed low-to-moderate magnitudes of correspondence between parent- and adolescent-reports of parental monitoring behaviors and parental knowledge. Adolescent self-reported delinquent behavior related to parent and adolescent reports of parental monitoring behaviors and parental knowledge, with adolescents who self-reported engagement in delinquent behaviors evidencing lower levels of parental knowledge and higher levels of poor monitoring compared to adolescents who did not self-report engagement in delinquent behaviors. Adolescent self-reported engagement in delinquent behaviors evidenced stronger links to parental monitoring when based on adolescent reports of monitoring (relative to parent reports), whereas stronger links held between adolescent self-reported delinquent behavior and parental knowledge when based on parent reports of knowledge (relative to adolescent reports). Conclusions Links between monitoring and adolescents’ delinquent behavior vary by the kind of monitoring measure completed as well as the informant completing the measure. These findings inform measurement selection in research and clinical assessments of parental monitoring and adolescent delinquent behavior. PMID:27482171

  13. Insight into the Earthquake Risk Information Seeking Behavior of the Victims: Evidence from Songyuan, China

    Directory of Open Access Journals (Sweden)

    Shasha Li

    2017-03-01

    Full Text Available Efficient risk communication is a vital way to reduce the vulnerability of individuals when facing emergency risks, especially regarding earthquakes. Efficient risk communication aims at improving the supply of risk information and fulfilling the need for risk information by individuals. Therefore, an investigation into individual-level information seeking behavior within earthquake risk contexts is very important for improved earthquake risk communication. However, at present there are very few studies that have explored the behavior of individuals seeking earthquake risk information. Under the guidance of the Risk Information Seeking and Processing model as well as relevant practical findings using the structural equation model, this study attempts to explore the main determinants of an individual’s earthquake risk information seeking behavior, and to validate the mediator effect of information need during the seeking process. A questionnaire-based survey of 918 valid respondents in Songyuan, China, who had been hit by a small earthquake swarm, was used to provide practical evidence for this study. Results indicated that information need played a noteworthy role in the earthquake risk information seeking process, and was detected both as an immediate predictor and as a mediator. Informational subjective norms drive the seeking behavior on earthquake risk information through both direct and indirect approaches. Perceived information gathering capacity, negative affective responses and risk perception have an indirect effect on earthquake risk information seeking behavior via information need. The implications for theory and practice regarding risk communication are discussed and concluded.

    The growing amount of information provided via web-based information technologies forces the users of these technologies to stop seeking for information before having acquired all available information. This stopping decision is either made actively following clear guidelines or subconsciously based on the seeker's intuition. This book analyzes the aforementioned duality by developing and testing a multi-theoretical research model dealing with information seeking stopping behavior in online scenarios. Thus, by delivering insights into the mechanisms that influence information seeking activitie

    2015-01-01

    Background Over 80% of people in methadone treatment smoke cigarettes, and existing smoking cessation interventions have been minimally effective. Objective To develop an Information-Motivation-Behavioral Skills (IMB) Model of behavior change based smoking cessation intervention for methadone maintained smokers, we examined smoking cessation related information, motivation, and behavioral skills in this population. Methods Current or former smokers in methadone treatment (n=35) participated in focus groups. Ten methadone clinic counselors participated in an individual interview. A content analysis was conducted using deductive and inductive approaches. Results Commonly known information, motivation, and behavioral skills factors related to smoking cessation were described. These factors included: the health effects of smoking and treatment options for quitting (information); pregnancy and cost of cigarettes (motivators); and coping with emotions, finding social support, and pharmacotherapy adherence (behavioral skills). Information, motivation, and behavioral skills factors specific to methadone maintained smokers were also described. These factors included: the relationship between quitting smoking and drug relapse (information), the belief that smoking is the same as using drugs (motivator); and coping with methadone clinic culture and applying skills used to quit drugs to quitting smoking (behavioral skills). Information, motivation, and behavioral skills strengths and deficits varied by individual. Conclusions Methadone maintained smokers could benefit from research on an IMB Model based smoking cessation intervention that is individualized, addresses IMB factors common among all smokers, and also addresses IMB factors unique to this population.

    This study aimed to establish teenage and young adult cancer survivors (TYACS') specific interest in receiving information on physical activity, diet, smoking, and alcohol consumption and their preferences regarding the delivery, format, and timing of such health behavior information. TYACS aged 13-25 years were invited to complete a questionnaire assessing the advice they had received in the past and their preferences on when and how health behavior information should be delivered. A total of 216 TYACS (mean age: 20 years; mean age at diagnosis: 16 years) completed the questionnaire. Approximately 40% of TYACS received no advice on physical activity and diet, and more than half (54%) received no advice on weight management. The majority (>70%) reported receiving no advice on smoking or alcohol consumption. Interest in receiving lifestyle advice was high overall (71%) but varied across behaviors, with TYACS reporting a greater level of interest in receiving advice on health protective behaviors (physical activity and diet) than health risk behaviors (smoking and alcohol consumption) (∼85% vs. ∼15%, respectively). TYACS reported seeking health behavior information from health professionals and were most interested in information delivered online or in the form of a mobile app. Similar proportions (18%-29%) felt health behavior information should first be provided before, during, immediately after, and post-treatment. It is evident that there is a need to develop lifestyle interventions in a range of formats available to TYACS throughout the care pathway to address the health behavior information needs of young people with cancer.

  3. A Network Diffusion Model of Food Safety Scare Behavior considering Information Transparency

    2017-01-01

    Full Text Available This study constructs the network diffusion model of food safety scare behavior under the effect of information transparency and examines the network topology and evolution characteristics of food safety scare behavior in a numerical simulation. The main conclusions of this study are as follows. (1 Under the effect of information transparency, the network degree distribution of food safety scare behavior diffusion demonstrates the decreasing characteristics of diminishing margins. (2 Food safety scare behavior diffusion increases with the information dissemination rate and consumer concern about food safety incidents and shows the characteristics of monotone increasing. And with the increasing of the government food safety supervision information transparency and media food safety supervision information transparency, the whole is declining characteristic of diminishing marginal. In addition, the extinction of food safety scare behavior cannot be achieved gradually given a single regulation of government food safety supervision information transparency and media food safety supervision information transparency. (3 The interaction effects between improving government food safety supervision information transparency or media food safety supervision information transparency and declining consumer concerns about food safety incidents or information transmission rate can engender the suppression of food safety scare behavior diffusion.

    Families, clinicians and researchers involved with varying neurological disorders face amazing challenges to understand, treat, and assist the people they are serving. Autism brings unique challenges and serves as an important model for the application of important concepts in information technology and telemedicine. The rising incidence of autism with limited professional resources has led to more consideration for using information technology and related specialties to link families and professionals, and to implement strategies which implement information technology to improve the outcomes for individuals with autism and their families. These are reviewed in context of the unique health, education, and the research issues facing those dealing with autism.

    Product-harm crises usually lead to product recalls, which may cause consumers concern about the product quality and safety. This study systematically examines customers' immediate responses to the Volkswagen product recall crisis in China. Particular attention was given to customers' responses to the risk information influencing their behavioral intentions. By combining the protective action decision model and the heuristic-systematic model, we constructed a hypothetical model to explore this issue. A questionnaire survey was conducted to collect data involving 467 participants drawn from the customers of Volkswagen. We used structural equation modeling to explore the model. The results show that customers' product knowledge plays an important role in their responses to the crisis. Having more knowledge would make them perceive a lower risk, but they might need even more information, making them more likely to seek and process information, and subsequently increasing their positive behavioral intentions toward the firm (that is pro-firm behavioral intentions). Risk perception increased customers' information needs, information seeking, and information processing but decreased their pro-firm behavioral intentions. In addition to promoting information seeking, information needed to also facilitate customers' systematic processing and thus increase their behavioral intentions to take corrective action. Customers' behavioral intentions were also spurred by systematic processing, but failed to be predicted by information seeking. In summary, theoretical and practical implications and suggestions for further research are also discussed. © 2015 Society for Risk Analysis.

    Full Text Available Background: Improving human behavior toward Avian influenza may lessen the chance to be infected by Avian influenza. This study aimed to identify several factors influencing behavior in the community.Method: A cross-sectional study was conducted in July 2008. Behavior regarding Avian influenza was measured by scoring the variables of knowledge, attitude, and practice. Subjects were obtained from the sub district of Limo, in Depok, West Java, which was considered a high risk area for Avian influenza. The heads of household as the sample unit were chosen by multi-stage sampling.Results: Among 387 subjects, 29.5% of them was had good behavior toward Avian influenza. The final model revealed that gender and access to health information were two dominant factors for good behavior in preventing Avian influenza. Compared with men, women had 67% higher risk to have good behavior [adjusted relative risk (RRa = 1.67; 95% confidence interval (CI = 0.92-3.04; P = 0.092]. Compared to those with no access to health information, subjects with access to health information had 3.4 fold increase to good behavior (RRa = 3.40; 95% CI =  0.84-13.76; P = 0.087.Conclusion: Acces to health information concerning Avian influenza was more effective among women in promoting good behavior toward preventing Avian influenza.

    1979-06-01

    The swimming performances of the Canadian Team at the 1976 Olympic Games were categorized as being improved or worse than previous best times in the events contested. The two groups had been previously assessed on the Psychological Inventories for Competitive Swimmers. A stepwise multiple-discriminant analysis of the inventory responses revealed that 13 test questions produced a perfect discrimination of group membership. The resultant discriminant functions for predicting performance classification were applied to the test responses of 157 swimmers at the 1977 Canadian Winter National Swimming Championships. Using the same performance classification criteria the accuracy of prediction was not better than chance in three of four sex by performance classifications. This yielded a failure to locate a set of behavioral factors which determine swimming performance improvements in elite competitive circumstances. The possibility of sets of factors which do not discriminate between performances in similar environments or between similar groups of swimmers was raised.

    2018-01-01

    Given the wide use of social media, these platforms have become important channels for understanding health-related information engagement processes. Reddit is a social media platform dedicated to user-generated content and discourse around the world. However, little research exists regarding use of the platform. Guided by the diffusion of innovation theory, the purpose of this study was to analyze Reddit users' behaviors on the platform related to perceptions of information credibility, health information seeking, and behavioral enactment of information found. Data were collected via survey from Reddit users around the world (n = 389). Data suggest that although Reddit use and perceived information credibility are unrelated to acting on the information found on Reddit, users who are specifically seeking health-related information are more likely to enact the information in their lives. Implications from the findings suggest important considerations for communication scholars, media advocates, and health promotion practitioners.

    Full Text Available The paper focuses on the creation of enterprise management information systems with the property of behavior. Behavior of information system is considered from the standpoint of its functions targeted expansion; the need for them arises from the variability of the external and internal environment. To create a system with behavior, integrated information systems are encouraged to be used constructed from highly specialized, low functional applications. Classification criteria of information systems with behavior are proposed by a set of functions, by options of control transfer to the application, by the integration level of information system components. Classification is revealed by integration levels of information system components. Within the classification four options for structural models of information systems are suggested. The first option is based on the integration of message brokers with achieving of automatic data transfer and the launch of the relevant applications. The second option is based on an integrated database that enables applications to operate in accordance with established regulations. The third version of the integration is carried out on the level of services and gives the possibility to build structures with preliminary uncertain configuration of intern applications for the actual problem solution. The fourth option is based on integration level of the interpretation of metadata for distributed database systems and applications that interact with these databases. The system behavior comes into existence in case of new application automatically exchanges input and output data with the other components of information system and has the possibility of flexible parameter setting of functions interaction.

    2015-01-01

    To investigate the effect of nutritional information disclosure on consumers' nutritional perception, attitude, and behavioral intention to purchase the food item. Questionnaires were distributed measuring nutritional perception, attitude, and behavioral intention with different nutritional information about the food (no information, calories only, and six nutritional content information items: food weight(g), calories(kcal), protein(g), sugar(g), sodium(g), and saturated fat(g)). Food items shown to the respondents were hamburgers and bibimbap. Descriptive analysis, analysis of variance, and multiple regression were used in order to examine the effects of nutritional information levels and different food items on consumers' behavioral intentions. Nutritional perception, food attitude, and food choice intention were all affected by levels of nutritional information and different food items. Also, food attitude was a predictor of food choice behavioral intention and was affected by different food items as well. However, results of the study found that objective and subjective knowledge of individuals are not related to their nutritional perception, attitude, and behavioral intention. Results of this study would help restaurant managers to prepare for consumers' demand on disclosure of nutritional information and adjust their menu ingredients for consumers' healthy food inquiries in order to respond to consumers' interests in nutritional information and ensure consumers satisfaction with the perceived nutritional value of food.

    2016-01-01

    This study explored the key factors underlying people's anti-nuclear behavioral intentions. The protective action decision model and the heuristic–systematic model were integrated and adapted from a risk information perspective to construct a hypothetical model. A questionnaire study was conducted on a sample of residents near the Haiyang Nuclear Power Plant, which is under construction in Shandong Province, China (N=487). Results show that, as expected, perceived knowledge is vital in predicting people's information insufficiency, information seeking, systematic processing, and risk perception. Moreover, the inverted U relationship between perceived knowledge and anti-nuclear behavioral intentions is indicated in the study. Information insufficiency and information seeking also significantly predict systematic processing. Furthermore, people's behavioral intentions are motivated by risk perception but fail to be stimulated by systematic processing. Implications and recommendations for future research are discussed. - Highlights: • The study explores anti-nuclear behavior from a risk information perspective. • Risk perception and knowledge matter to anti-nuclear behavioral intentions. • Inverted U relationship between knowledge and behavioral intentions is indicated. • More understanding of nuclear power could reduce public opposition.

  8. Information theory applied to econophysics: stock market behaviors

    2014-08-01

    The use of data compressor techniques has allowed to recognize magnetic transitions and their associated critical temperatures [E.E. Vogel, G. Saravia, V. Cortez, Physica A 391, 1591 (2012)]. In the present paper we introduce some new concepts associated to data recognition and extend the use of these techniques to econophysics to explore the variations of stock market indicators showing that information theory can help to recognize different regimes. Modifications and further developments to previously introduced data compressor wlzip are introduced yielding two measurements. Additionally, we introduce an algorithm that allows to tune the number of significant digits over which the data compression is due to act complementing, this with an appropriate method to round off the truncation. The application is done to IPSA, the main indicator of the Chilean Stock Market during the year 2010 due to availability of quality data and also to consider a rare effect: the earthquake of the 27th of February on that year which is as of now the sixth strongest earthquake ever recorded by instruments (8.8 Richter scale) according to United States Geological Survey. Along the year 2010 different regimes are recognized. Calm days show larger compression than agitated days allowing for classification and recognition. Then the focus turns onto selected days showing that it is possible to recognize different regimes with the data of the last hour (60 entries) allowing to determine actions in a safer way. The "day of the week" effect is weakly present but "the hour of the day" effect is clearly present; its causes and implications are discussed. This effect also establishes the influence of Asian, European and American stock markets over the smaller Chilean Stock Market. Then dynamical studies are conducted intended to search a system that can help to realize in real time about sudden variations of the market; it is found that information theory can be really helpful in this respect.

    Context has been addressed as an influential factor of human information behavior. However, there is no consensus on what constitutes a context, or what the relationship between context and information behavior is. In this paper we explore the notions of context and describe the relationship between context and information behavior based on empirical findings, and reviews of current· literature. Our finding suggests that context is stratified and dynamic.

    A context is consisted of several situations, and each situation is defined by a set of related contextual factors. In this way, we propose a new approach to represent the context and situation. At different levels of context, multiple relationships between context and information behavior are identified, including the association relationship, the interaction relationship, and the one-directional relationship. These findings substantiate the concept of situation in Dervin's Sense-making approach, the concept of information horizon proposed by Sonnenwald, and Ingwersen's cognitive model of IR interaction. The multiple relationships between context and information behavior imply that information behavior is related to, but not equal to the process of problem solving. In contrast, information behavior can be viewed as a response of certain situation in the context.

    The aim of this study was to calculate the number and costs of hospital bed-days due to alcohol use in Ireland over the five year period 2000 to 2004. Age and sex specific Irish alcohol-attributable-fractions (AAFs) were developed by combining international risk estimates with Irish consumption data where available; where not available international AAFs were used. These were applied to national datasets to count the number and costs of bed-days wholly caused and prevented by alcohol and that proportion of bed-days that were partially caused and prevented by alcohol. Between 2000 and 2004, alcohol was estimated to have caused 3,428,973 (10.3%) and prevented 529,239 (1.6%) of hospital bed-days, giving a net number of bed-days due to alcohol of 2,899,734 (8.7%). Over this period the hospital inpatient costs attributed to the negative effects of alcohol were 953,126,381 euros, the costs attributed to hospitalisations prevented were 147,968,164 euros; giving net costs of alcohol-attributed bed-days of 805,158,217 euros. Chronic conditions accounted for 3,262,408 (95%) hospital bed-days due to the harmful effects of alcohol. Conditions not wholly due to alcohol accounted for 2,297,412 (67%) hospital bed-days due to the harmful effects of alcohol. The negative impacts of alcohol were greater than previously thought and spread across the whole population.

    Full Text Available The aim of this study is to analyse the efficiency of Estonian grain farms after Estonia’s transition to a market economy and during the accession period to the European Union (EU. The non-parametric method Data Envelopment Analysis (DEA was used to estimate the total technical, pure technical and scale efficiency of Estonian grain farms in 2000–2004. Mean total technical efficiency varied from 0.70 to 0.78. Of the grain farms 62% are operating under increasing returns to scale. Solely based on the DEA model it is not possible to determine optimum farm scale and the range of Estonian farm sizes operating efficiently is extensive. The most pure technically efficient farms were the smallest and the largest but the productivity of small farms is low compared to larger farms because of their small scale. Therefore, they are the least competitive. Since pre-accession period to the EU, large input slacks of capital have replaced the former excessive use of labour and land. This raises the question about the effects on efficiency of the EU’s investment support schemes in new member states.;

A total of 158 Medical doctors (128 males and 30 (females were used for the study. The overall response rate was around 70.2 percent. Medical doctors need specific medical information to enhance their knowledge on a day-to-day basis, particularly with the information explosion such as e-mail and internet facilities. Medical doctors prefer the use of publishers catalogues as the most important source for new developments in their relevant fields. Many do not have access to local data bases that are supposed to have remarkable impact on their information gathering behaviour.

    Investigation of the health information behavior, self-rated health, confidence in health issues and specific attitudes to health among the South Tyrolean population. Our study is an epidemiological cross-sectional study; data were collected via telephone interviews, using a questionnaire developed for this purpose that covered various aspects of information and health-related behavior. For the elaboration of the typology of the most distinctive stereotypes in terms of health information and health-related behavior, a hierarchical cluster analysis was performed. We assessed 504 correct telephone interviews. The majority of the respondents considered themselves health-conscious and preferred heterogeneous information media. The most used information media for health issues were mass media, i. e. newspapers or magazines and television or radio. The internet was used less as a source of information. Younger individuals assessed themselves to be healthier than older people, and older women aged 65 years or more were the most health-impaired group. Respondents had greatest confidence in their general practitioner, their own feeling or experience. Thus, in terms of health information and health behavior, the following four classes of people could be distinguished, namely "internet information elite", "robust fatalists", "stricken" and "health-conscious mainstreamers". Our results show that the South Tyrolean population has a high level of health consciousness and gathers health information from various media. The characterization of different patient typologies of information processing in combination with health-related behavior indicates that information about health and illness should be appropriately addressed to the respective stereotype. © Georg Thieme Verlag KG Stuttgart · New York.

    The purpose of this study was to examine neurological impairment in combination with information-motivation-behavioral skills (IMB) variables. The study tests the role of IMB variables as mediators of antecedent variables of demographics, life stress, social support, and neurological impairment with outcome measures of HIV preventive and risk behaviors in a sample of HIV-positive, alcohol-using adults (n = 250) with a history of alcohol abuse/dependence. Neurological impairment was measured with the Color Trails Test (CTT). Average performance on the CTT by the sample was substantially worse than established norms. In a directional latent variable model, neurological impairment directly predicted lower transmission knowledge scores and poorer performance on an observational condom skills assessment. Greater neurological impairment was significantly associated with greater age. Future interventions geared toward HIV+ adults who use alcohol should take into consideration HIV-related and age-related neurological functioning which may impede the facilitation of safe sex behaviors.

    Health information and communication technologies (ICTs) are increasingly used but little is known about routine exposure to health information from ICTs and its associations with health behaviors. A territory-wide population-based dual landline and mobile telephone survey was conducted in 2016 in Hong Kong, where smartphone ownership and Internet access are among the most prevalent, easiest and fastest in the world. Health information exposure from traditional sources (television/radio/newspaper/magazine), Internet websites, social media sites and instant messaging (IM); and information on smoking, alcohol consumption and physical activity were recorded. Prevalence was weighted by age, sex and education level of the general population. Multinomial logistic regression was used to assess the association of health information exposure with smoking and alcohol consumption, whilst multivariable linear regression was used to assess the association with frequency of moderate and vigorous physical activity (days/week). Of 3063 respondents, most (71.6%) were often or sometimes exposed to health information from traditional sources, followed by Internet websites (40.9%), social media sites (40.7%), and IM (27.0%). Respondents with lower education and household income were less frequently exposed to health information from Internet websites, social media sites and IM (all P < 0.001). Health information exposure from IM was associated with being never smokers, and more frequent moderate and vigorous physical activity (all P for trend <0.05). Health information exposure from IM was least frequent but associated with healthier behaviors. Further public health education campaigns can consider using IM to deliver information, particularly to disadvantaged groups. Copyright © 2018 Elsevier Inc. All rights reserved.

    Genetic testing, especially in pharmacogenomics, can have a major impact on patient care. However, most physicians do not feel that they have sufficient knowledge to apply pharmacogenomics to patient care. Online information resources can help address this gap. We investigated physicians' pharmacogenomics information needs and information-seeking behavior, in order to guide the design of pharmacogenomics information resources that effectively meet clinical information needs. We performed a formative, mixed-method assessment of physicians' information-seeking process in three pharmacogenomics case vignettes. Interactions of 6 physicians' with online pharmacogenomics resources were recorded, transcribed, and analyzed for prominent themes. Quantitative data included information-seeking duration, page navigations, and number of searches entered. We found that participants searched an average of 8 min per case vignette, spent less than 30 s reviewing specific content, and rarely refined search terms. Participants' information needs included a need for clinically meaningful descriptions of test interpretations, a molecular basis for the clinical effect of drug variation, information on the logistics of carrying out a genetic test (including questions related to cost, availability, test turn-around time, insurance coverage, and accessibility of expert support).Also, participants sought alternative therapies that would not require genetic testing. This study of pharmacogenomics information-seeking behavior indicates that content to support their information needs is dispersed and hard to find. Our results reveal a set of themes that information resources can use to help physicians find and apply pharmacogenomics information to the care of their patients.

    Surgical excellence demands teamwork. Poor team behaviors negatively affect team performance and are associated with adverse events and worse outcomes. Interventions to improve surgical teamwork focusing on frontline team members' nontechnical skills have proliferated but shown mixed results. Literature on teamwork in organizations suggests that team behaviors are also contingent on psycho-social, cultural and organizational factors. This study examines factors influencing surgical team behaviors in order to inform more contextually sensitive and effective approaches to optimizing surgical teamwork. Qualitative study of cardiac surgical teams in a large US teaching hospital included 34 semi-structured interviews. Thematic network analysis was used to examine perceptions of ideal teamwork and factors influencing team behaviors in the OR. Perceptions of ideal teamwork were largely shared, but team members held discrepant views of which team and leadership behaviors enhanced or undermined teamwork. Other factors impacting team behaviors related to: local organizational culture, including management of staff behavior; variable case demands and team members' technical competence; fitness of organizational structures and processes to support teamwork. These factors affected perceptions of what constituted optimal interpersonal and team behaviors in the OR. Team behaviors are contextually contingent and organizationally determined, and beliefs about optimal behaviors are not necessarily shared. Interventions to optimize surgical teamwork requires establishing consensus regarding best practice, ability to adapt as circumstances require, and organizational commitment to addressing contextual factors that impact teams.

    This study aimed to examine whether social capital (bonding and bridging social capital) attenuate the effect of low functional health literacy on health information resources, efficacy, and behaviors. In-person interviews were conducted with 1,000 residents in Seoul, Korea, in 2011. The authors found that respondents' functional health literacy had positive effects on the scope of health information sources and health information self-efficacy but not health information-seeking intention. Respondents' social capital had positive effects on the scope of health information sources, health information efficacy, and health information-seeking intention. The authors found (a) a significant moderation effect of bridging social capital on the relation between health literacy and health information self-efficacy and (b) a moderation effect of bonding social capital on the relation between health literacy and health information-seeking intention.

    Full Text Available Abstract Background Although vaccinations are critical for preventing emerging infectious diseases, scant research has been conducted on risk communication. With socio-economic characteristics, health behavior, and underlying diseases under control, we investigated associations between media use, health information-seeking behavior, health information type, and vaccination in the population. Methods This study relied on a national survey of Korean adults (n = 1367. Participants were adult males and females age 20 and older. Web and face-to-face surveys were conducted throughout July 2014. The main outcome was vaccination (categorized as yes or no. Independent variables were time spent on media, frequency of health information-seeking behavior, and types of health information sought. Results Controlling for co-variates, logistic regression analysis was conducted to identify factors that influence Korean adults being vaccinated. Results revealed that accessible information about emerging infectious diseases, listening to the radio, and reading the newspaper were associated with increased odds of being vaccinated. Active seeking health information as well as being female and of higher socio-economic status were positively correlated with Korean adults being vaccinated. Conclusion It is critical to promote health information-seeking behavior and use diverse media channels to increase acceptance and awareness of emerging infectious diseases and vaccinations. Because there are differences in vaccination awareness depending on social class, it is critical to reduce communication inequality, strengthen accessibility to vaccinations, and devise appropriate risk communication strategies that ensure Korean adults receive vaccinations.

    Low health literacy remains an extremely common and problematic issue, given that individuals with lower health literacy are more likely to experience health challenges and negative health outcomes. In this study, we use the first three stages of the innovation-decision process found in the theory of diffusion of innovations (Rogers, 2003). We incorporate health literacy into a model explaining how perceived health knowledge, information sharing, attitudes, and behavior are related. Results show that health information sharing explains 33% of the variance in behavioral intentions, indicating that the communicative practice of sharing information can positively impact health outcomes. Further, individuals with high health literacy tend to share less information about heart health than those with lower health literacy. Findings also reveal that perceived heart-health knowledge operates differently than health literacy to predict health outcomes.

This research’s purposes were: 1 to analyze the students’ motivation; 2 to analyze the critical thinking and academic verification; 3 to analyze the information-seeking behavior. This study used quantitative approach through survey among 1125 respondents in nine clusters, i.e. Central, East, North, West, and South of Jakarta, Tangerang, Bekasi, Depok, and Bogor. Schools sampling based on "the best schools rank" by the government, while respondents have taken by accidental in each school. Construct of questionnaire included measurement of motivation, critical thinking and academic verification, and the information-seeking behavior at all. The results showed that the motivations of the use of Internet were dominated by habit to interact and be entertained while on the academic needs are still relatively small but increasing significantly. Students’ self-efficacy, performance and achievement goals tend to be high motives, however the science learning value, and learning environment stimulation were average low motives. High school students indicated that they think critically about the various things that become content primarily in social media but less critical of the academic information subjects. Unfortunately, high school students did not conducted academic verification on the data and information but students tend to do plagiarism. Key words: Student motivation, critical thinking, academic verification, information-seeking behavior, digital generation.

    2006-08-01

    The growing diversity of the online health information community is increasingly cited as a limiting factor related to the potential of the Internet as an effective health communication channel and information resource. Public-access Internet portals and decreasing costs of personal computers have created a consensus that unequal access to information, or a "Digital Divide," presents a like problem specific to health care consumers. Access to information, however, is an essential part of the consumer-centric framework outlined in the recently proposed U.S. National Health Information Infrastructure (NHII) and Health Architecture initiatives. To date little research has been done to differentiate the types of health information sought on the Web by different subgroups, linking user characteristics and health-seeking behaviors. Data from a study of consumer Web search activity in a post-intervention era serves as a natural experiment, and can identify whether a "digitally underserved group" persists in the United States. Such an environment would serve to exclude traditionally underserved groups from the benefits of the planned national heath information infrastructure. This exploratory technology assessment study seeks to differentiate and delineate specific behaviors, or lack of desired behaviors, across targeted health care subgroups. Doing so allows the design of more effective strategies to promote the use of the Web as a health education and health promotion tool, under the envisioned shared decision-making, consumer-centric health information model.

    2006-07-01

    HIV-positive persons who do not maintain consistently high levels of adherence to often complex and toxic highly active antiretroviral therapy (HAART) regimens may experience therapeutic failure and deterioration of health status and may develop multidrug-resistant HIV that can be transmitted to uninfected others. The current analysis conceptualizes social and psychological determinants of adherence to HAART among HIV-positive individuals. The authors propose an information-motivation-behavioral skills (IMB) model of HAART adherence that assumes that adherence-related information, motivation, and behavioral skills are fundamental determinants of adherence to HAART. According to the model, adherence-related information and motivation work through adherence-related behavioral skills to affect adherence to HAART. Empirical support for the IMB model of adherence is presented, and its application in adherence-promotion intervention efforts is discussed.

    2013-09-01

    Clinicians and researchers are increasingly using technology-based behavioral health interventions to improve intervention effectiveness and to reach underserved populations. However, these interventions are rarely informed by evidence-based findings of how technology can be optimized to promote acquisition of key skills and information. At the same time, experts in multimedia learning generally do not apply their findings to health education or conduct research in clinical contexts. This paper presents an overview of some key aspects of multimedia learning research that may allow those developing health interventions to apply informational technology with the same rigor as behavioral science content. We synthesized empirical multimedia learning literature from 1992 to 2011. We identified key findings and suggested a framework for integrating technology with educational and behavioral science theory. A scientific, evidence-driven approach to developing technology-based interventions can yield greater effectiveness, improved fidelity, increased outcomes, and better client service.

    In order to benefit from a coronary artery bypass graft (CABG) surgery, patients must adhere to medical recommendations and health advices. Despite the importance of adherence in CABG patients, adherence rates are disappointingly low. Despite the low adherence rates, very few articles regarding adherence-enhancing intervention among heart patients have been published. The goal of this study was to assess the effects of the Information-Motivation-Behavioral Skills (IMB) model-based intervention on the IMB model constructs among patients undergoing CABG and to evaluate the relationship of information, motivation, and behavioral skills with adherence. A total of 152 CABG patients were randomly assigned to either an intervention group or to a standard care control group. Participants completed pretest measures and were reassessed 1 month later. Findings showed mixed support for the effectiveness of the intervention. There was a significant effect of IMB intervention on information and motivation of patients, but no significant effect on behavioral skills. Furthermore, the results revealed that intervention constructs (information, motivation, and behavioral skills) were significantly related to patients' adherence. Findings provided initial evidence for the effectiveness of IMB-based interventions on the IMB constructs and supported the importance of these constructs to improve adherence; however, there are additional factors that need to be identified in order to improve behavioral skills more effectively.

    A few studies have examined the specific informational needs of the population with amyotrophic lateral sclerosis. The aims of this study were to describe the information-seeking behavior and information needs of patients with amyotrophic lateral sclerosis and their families in Korea by analyzing messages from an online patient community. A total of 1047 messages from the question and answer forum of the "Lou Gehrig's Disease Network" (http://cafe.daum.net/alsfree) from January 2010 to September 2015 were collected. The word frequency, main questions, and asker of the messages were analyzed and coded. Terms such as "hospital," "mother," "father," "gastrostomy," and "ALS" were most frequently identified. The most commonly mentioned main topic was about disease-specific information, while the most frequent subcategory was symptoms or management of symptoms. Other prominent categories concerned information about treatment, rehabilitation, and the medical system. The people who wrote the questions were mostly the son/daughter of patients with amyotrophic lateral sclerosis. Patients with amyotrophic lateral sclerosis and their family members commonly obtained information by posting their inquiries online and have a variety of questions regarding amyotrophic lateral sclerosis in this study. The findings of this study can be used as a base of information for developing educational programs and resources for patients with amyotrophic lateral sclerosis and their families.

  4. Behavior Selection of Mobile Robot Based on Integration of Multimodal Information

    Chen, Bin; Kaneko, Masahide

    Recently, biologically inspired robots have been developed to acquire the capacity for directing visual attention to salient stimulus generated from the audiovisual environment. On purpose to realize this behavior, a general method is to calculate saliency maps to represent how much the external information attracts the robot's visual attention, where the audiovisual information and robot's motion status should be involved. In this paper, we represent a visual attention model where three modalities, that is, audio information, visual information and robot's motor status are considered, while the previous researches have not considered all of them. Firstly, we introduce a 2-D density map, on which the value denotes how much the robot pays attention to each spatial location. Then we model the attention density using a Bayesian network where the robot's motion statuses are involved. Secondly, the information from both of audio and visual modalities is integrated with the attention density map in integrate-fire neurons. The robot can direct its attention to the locations where the integrate-fire neurons are fired. Finally, the visual attention model is applied to make the robot select the visual information from the environment, and react to the content selected. Experimental results show that it is possible for robots to acquire the visual information related to their behaviors by using the attention model considering motion statuses. The robot can select its behaviors to adapt to the dynamic environment as well as to switch to another task according to the recognition results of visual attention.

    The ability to locate information pertinent to guide clinical practice is important for quality nursing care and patient safety. To date, little is known about the transfer of information literacy skills as student nurses transition to clinical practice as new graduates. This study begins to address this gap from the perspective of student nurses, recent nurse graduates (RNs), nurse leaders and library staff. To describe the information-seeking behaviors of student nurses and RNs within their clinical settings. This is a descriptive study that included both cross-sectional surveys and key informant interviews. Participants were senior-level undergraduate students and recently graduated RNs (graduated since 2008), and nurse leaders and library staff employed in one of the clinical sites accepting undergraduate students from the McMaster Mohawk and Conestoga BScN program. The study was completed in two large hospital corporations in Hamilton, Ontario, Canada. Student nurses and RNs were invited to complete online surveys to assess their access to and use of information sources and resources within clinical practice. Students completed a survey comprised of five open-ended questions, while RNs completed a survey comprised of 13 fixed choice and open-ended questions. Nurse leaders and library staff participated in qualitative interviews to verify the extent and availability of information resources. Eighteen RNs and 62 students completed their respective surveys. Three categories of information sources and resources were identified: electronic, print and interpersonal. Electronic sources of information were the most used resource by both students and RNs. More RNs reported using interpersonal sources, while students reported using more print sources of information. Recent RN graduates meet the Canadian Association of Schools of Nursing performance indicators related to information access for the entry to practice Nursing Informatics competencies.

    Full Text Available Rare diseases by definition do not occur often and it is difficult to provide palliative care for those affected due to the lack of information and treatment for those rare diseases. The families of those with rare diseases bear a heavy burden and have a harder time than even the families of disabled people. This research’s goal is to provide the families of those with rare diseases with information on how to provide care for their family members. The study uses the qualitative research method of semi-structured interview. We interviewed 10 rare disease children and adolescents’ primary caregivers. The results of the study indicated that if no one suffers from the rare diseases in their family, primary caregivers are not aware of the rare disease information. After their initial diagnosis, the caregivers will want to know how to best care for their family member, from how best to provide supportive care to providing physical therapy, in order to improve their quality of life and prognosis. When they discover their child’s disease is incurable, primary caregivers need information about social welfare and their child’s future. The main source of medical care information is provided by hospitals and patient-support organizations. Regarding information behavior, primary caregivers employ the information which they obtain and they either check the information they obtain with a professional authority, multiple sources, or compare it with patient experience to validate if the information is accurate or not. Finally, primary caregivers are glad to share what they find with other families that have children with a rare disease. They may use different ways of sharing information such as the Internet or face to face. [Article content in Chinese

  7. Altruistic Behavior and Cooperation: The Role of Intrinsic Expectation When Reputational Information is Incomplete

    Full Text Available Altruistic behavior is known to be conditional on the level of altruism of others. However, people often have no information, or incomplete information, about the altruistic reputation of others, for example when the reputation was obtained in a different social or economic context. As a consequence, they have to estimate the other's altruistic intentions. Using an economic game, we showed that without reputational information people have intrinsic expectations about the altruistic behavior of others, which largely explained their own altruistic behavior. This implies that when no information is available, intrinsic expectations can be as powerful a driver of altruistic behavior as actual knowledge about other people's reputation. Two strategies appeared to co-exist in our study population: participants who expected others to be altruistic and acted even more altruistically themselves, while other participants had low expected altruism scores and acted even less altruistically than they expected others to do. We also found evidence that generosity in economic games translates into benefits for other social contexts: a reputation of financial generosity increased the attractiveness of partners in a social cooperative game. This result implies that in situations with incomplete information, the fitness effects of indirect reciprocity are cumulative across different social contexts.

    Full Text Available The high prevalence of risky irrational drug use behaviors mean that outpatients face high risks of drug resistance and even death. This study represents the first application of the Information-Motivation-Behavioral Skills (IMB model on rational drug use behavior among second-level hospital outpatients from three prefecture-level cities in Anhui, China. Using the IMB model, our study examined predictors of rational drug use behavior and determined the associations between the model constructs.This study was conducted with a sample of 1,214 outpatients aged 18 years and older in Anhui second-level hospitals and applied the structural equation model (SEM to test predictive relations among the IMB model variables related to rational drug use behavior.Age, information and motivation had significant direct effects on rational drug use behavior. Behavioral skills as an intermediate variable also significantly predicted more rational drug use behavior. Female gender, higher educational level, more information and more motivation predicted more behavioral skills. In addition, there were significant indirect impacts on rational drug use behavior mediated through behavioral skills.The IMB-based model explained the relationships between the constructs and rational drug use behavior of outpatients in detail, and it suggests that future interventions among second-level hospital outpatients should consider demographic characteristics and should focus on improving motivation and behavioral skills in addition to the publicity of knowledge.

    Many prior studies of technology adoption treat user intention as the single predictor of actual usage behavior. However, as many researchers of behavioral science have pointed out, multiple factors mediate the relationship between user intention and usage behavior. The present article explores the factors that mediate the relationship between intention and actual behavior. We develop a conceptual framework that is based on the Technology Acceptance Model III and behavior theory to further elicit system usage behavior and to confirm "intention stability" and "past experience" as two significant mediating factors in this relationship. The target system was a nursing information system that had been recently adopted by a medical center in central Taiwan. Data were collected using a questionnaire survey conducted in two rounds. Two hundred forty-five valid questionnaires were returned (response rate: 49%). Mediated moderation was analyzed to explore the presence of mediators or moderators between intention and behavior. The results support that intention stability is a mediated moderator and that prior experience is a moderator of the relationship between intention and behavior. These two factors increased by over 13.6% the explanatory power of intention on actual behavior. Furthermore, this study expanded the scope of prior research by confirming intention stability as a moderating variable between intention and behavior. Finally, this study identified the moderating effect of past experience on the intention-behavior relationship, indicating that past experience enhances the predictive power of intention on behavior. The findings of this study may assist hospital managers to better understand the nursing information system usage behaviors of nursing staff and to develop ways to enhance the intention stability of these staff. Managers may improve the familiarity of nursing staff with the system by increasing their system-related practice time. More experience should

    Sexual health is an important area of study-particularly for minority youth and youth living in disadvantaged neighborhoods. The purpose of the research was to examine the sources of sexual health information associated with youth adopting sexual risk reduction behaviors. Data collection took place in a small city in the Northeastern United States using cross-sectional behavioral surveys and modified venue-based sampling. Participants included 249 African American and Latino youth aged 13-24. Participants reported their sources of information about contraception and human immunodeficiency virus/sexually transmitted disease, such as TV/movies, parents, social media; their intentions to have sex; and condom and contraception use during their last sexual activity. Social media use, past pregnancy experience, past sexual history, age, and gender were also measured. Standard tests of bivariate association (chi-square and F tests) were used to examine initial associations between sexual risk reduction behavior and exposure to sexual risk reduction information on social media. Logistic regression models were used to test multivariate relationships between information sources and sexual risk reduction behavior. Youth who were exposed to sexual health messages on social media were 2.69 times (p < .05) and 2.49 times (p < .08) more likely to have used contraception or a condom at last intercourse, respectively. Parents, schools, or traditional media as information sources were not significantly associated with contractive use or condom use at last intercourse. Youth sexual behavior is increasingly informed by social media messages. Health practitioners should utilize social media as an important health promotion tool.

  12. Robotic Fish to Aid Animal Behavior Studies and Informal Science Learning

    Phamduy, Paul

    The application of robotic fish in the fields of animal behavior and informal science learning are new and relatively untapped. In the context of animal behavior studies, robotic fish offers a consistent and customizable stimulus that could contribute to dissect the determinants of social behavior. In the realm of informal science learning, robotic fish are gaining momentum for the possibility of educating the general public simultaneously on fish physiology and underwater robotics. In this dissertation, the design and development of a number of robotic fish platforms and prototypes and their application in animal behavioral studies and informal science learning settings are presented. Robotic platforms for animal behavioral studies focused on the utilization replica or same scale prototypes. A novel robotic fish platform, featuring a three-dimensional swimming multi-linked robotic fish, was developed with three control modes varying in the level of robot autonomy offered. This platform was deployed at numerous science festivals and science centers, to obtain data on visitor engagement and experience.

    Research on the information-seeking behaviors of dental practitioners is scarce. Knowledge of dentists’ information-seeking behaviors should advance the translational gap between clinical dental research and dental practice. A cross-sectional survey was conducted to examine the self-reported information-seeking behaviors of dentists in three dental practice-based research networks (PBRNs). A total of 950 dentists (65 percent response rate) completed the survey. Dental journals and continuing dental education (CDE) sources used and their influence on practice guidance were assessed. PBRN participation level and years since dental degree were measured. Full-participant dentists reported reading the Journal of the American Dental Association and General Dentistry more frequently than did their reference counterparts. Printed journals were preferred by most dentists. A lower proportion of full participants obtained their CDE credits at dental meetings compared to partial participants. Experienced dentists read other dental information sources more frequently than did less experienced dentists. Practitioners involved in a PBRN differed in their approaches to accessing information sources. Peer-reviewed sources were more frequently used by full participants and dentists with fifteen years of experience or more. Dental PBRNs potentially play a significant role in the dissemination of evidence-based information. This study found that specific educational sources might increase and disseminate knowledge among dentists. PMID:23382524

    Controversies exist regarding the effects of sex education in the schools and informal sex education obtained from parents, peers, the mass media, and other sources. Similarly, there is widespread interest in premarital sexual behavior, especially its determinants. This study presents several issues reflecting these concerns which have been the subject of much speculation but which have received little attention by researchers. The purpose of this study was to investigate--through the use of respondent reports--how formal and informal sex education influences premarital sexual behavior during college. A national probability sample of 1177 college students was studied using face-to-face interviews with approximately equal numbers of males and females. These interviews, which were conducted for the Institute for Sex Research, included questions about past and present sexual involvement and other attitudinal, behavioral and background variables. Accordingly, the data about sexual behavior and attitudes are based on the interviewees' self-reports. Indices were created which operationalized independent variables such as familial sexual conservatism, exposure to eroticism, perceived sex knowledge, and sexual exposure and assault during childhood and adolescence. Individual items reflecting childhood sex play, masturbation, current religiosity, religiosity while growing up, social class, sources of sex information, sex education in classrooms, and high school and college dating were used. The dependent variable, premarital sociosexual involvement, is a composite measure of incidence and prevalence of premarital heterosexual involvement which meets Guttman scaling criteria. An Automatic Interaction Detector analysis was used to determine the relative influences of reported sexualization variables on premarital sexual behavior. Major findings can be summarized as follows: Heterosexual behavior progresses in stepwise fashion from elementary to advanced levels of involvement

  5. Intrinsic activity in the fly brain gates visual information during behavioral choices.

    Full Text Available The small insect brain is often described as an input/output system that executes reflex-like behaviors. It can also initiate neural activity and behaviors intrinsically, seen as spontaneous behaviors, different arousal states and sleep. However, less is known about how intrinsic activity in neural circuits affects sensory information processing in the insect brain and variability in behavior. Here, by simultaneously monitoring Drosophila's behavioral choices and brain activity in a flight simulator system, we identify intrinsic activity that is associated with the act of selecting between visual stimuli. We recorded neural output (multiunit action potentials and local field potentials in the left and right optic lobes of a tethered flying Drosophila, while its attempts to follow visual motion (yaw torque were measured by a torque meter. We show that when facing competing motion stimuli on its left and right, Drosophila typically generate large torque responses that flip from side to side. The delayed onset (0.1-1 s and spontaneous switch-like dynamics of these responses, and the fact that the flies sometimes oppose the stimuli by flying straight, make this behavior different from the classic steering reflexes. Drosophila, thus, seem to choose one stimulus at a time and attempt to rotate toward its direction. With this behavior, the neural output of the optic lobes alternates; being augmented on the side chosen for body rotation and suppressed on the opposite side, even though the visual input to the fly eyes stays the same. Thus, the flow of information from the fly eyes is gated intrinsically. Such modulation can be noise-induced or intentional; with one possibility being that the fly brain highlights chosen information while ignoring the irrelevant, similar to what we know to occur in higher animals.

     This study evaluates usage patterns of online health information in parents with children undergoing elective or emergency surgical procedures.  We prospectively surveyed parents of children admitted to our institution for common emergency (appendicectomy, abscess drainage, gonadal torsion) or elective (herniotomy, orchidopexy) operations between March and September 2016. Each completed an anonymized modification of a previously published survey comprising 19 questions on demographic data, Internet usage, and review of Internet resources. Chi-square tests were used for categorical data with p  information in elective ( n  = 27; 54%) and emergency groups ( n  = 24;70.6%) than general practitioners or other health care workers. When condition-specific online information was sought, more than 95% felt that the information concurred with the doctor's. Most common reasons were for more information on the condition ( n  = 56; 90.3%) and on medical treatment ( n  = 52; 83.9%). Eighteen (18/62; 29%) parents reported excessively technical information. No significant difference in behavior was found comparing elective and emergency groups.  Approximately one quarter of parents do not access condition-specific online medical information despite high Internet penetration rates. More than half depend on friends and family for additional information, reflecting societal and cultural norms in our population. Surgeons must incorporate awareness of these behaviors during counselling. Georg Thieme Verlag KG Stuttgart · New York.

    The current study applied the Information-Motivation-Behavioral Skills (IMB) model (Fisher & Fisher, 1992; Fisher & Fisher, 1993) to identify factors associated with human immunodeficiency virus (HIV) transmission risk behavior among HIV-infected South Africans receiving antiretroviral therapy (ART), a population of considerable significance for curtailing, or maintaining, South Africa's generalized HIV epidemic. HIV prevention information, HIV prevention motivation, HIV prevention behavioral skills, and HIV transmission risk behavior were assessed in a sample of 1,388 South Africans infected with HIV and receiving ART in 16 clinics in KwaZulu-Natal, South Africa. Findings confirmed the assumptions of the IMB model and demonstrated that HIV prevention information and HIV prevention motivation work through HIV prevention behavioral skills to affect HIV transmission risk behavior in this population. Subanalyses confirmed these relationships for HIV transmission risk behavior overall and for HIV transmission risk behavior with partners perceived to be HIV-negative or HIV-status unknown. A consistent pattern of gender differences showed that for men, HIV prevention information and HIV prevention motivation may have direct links with HIV preventive behavior, whereas for women, the effect of HIV prevention motivation works through HIV prevention behavioral skills to affect HIV preventive behavior. These IMB model-based findings suggest directions for HIV prevention interventions with South African men and women living with HIV and on ART as an important component of overall strategies to contain South Africa's generalized HIV epidemic.

    For effective health promotion using health information technology (HIT), it is mandatory that health consumers have the behavioral intention to measure, store, and manage their own health data. Understanding health consumers' intention and behavior is needed to develop and implement effective and efficient strategies. To develop and verify the extended Technology Acceptance Model (TAM) in health care by describing health consumers' behavioral intention of using HIT. This study used a cross-sectional descriptive correlational design. We extended TAM by adding more antecedents and mediating variables to enhance the model's explanatory power and to make it more applicable to health consumers' behavioral intention. Additional antecedents and mediating variables were added to the hypothetical model, based on their theoretical relevance, from the Health Belief Model and theory of planned behavior, along with the TAM. We undertook structural equation analysis to examine the specific nature of the relationship involved in understanding consumers' use of HIT. Study participants were 728 members recruited from three Internet health portals in Korea. Data were collected by a Web-based survey using a structured self-administered questionnaire. The overall fitness indices for the model developed in this study indicated an acceptable fit of the model. All path coefficients were statistically significant. This study showed that perceived threat, perceived usefulness, and perceived ease of use significantly affected health consumers' attitude and behavioral intention. Health consumers' health status, health belief and concerns, subjective norm, HIT characteristics, and HIT self-efficacy had a strong indirect impact on attitude and behavioral intention through the mediators of perceived threat, perceived usefulness, and perceived ease of use. An extended TAM in the HIT arena was found to be valid to describe health consumers' behavioral intention. We categorized the concepts in

    Full Text Available eHealth literacy (eHEALS has yet to be examined with regard to need for cognition (NFC, as well as whether NFC moderates the relationship between eHealth literacy and seeking out online health information. Past research that has examined NFC as an interaction between whether interactivity on health web sites affected comprehension and attitudes, but no research to date has examined whether cognitive need interacts with eHEALS and subsequent information seeking behaviors. The present study tests eHEALS and its connection to need for cognition (NFC in the role of online health information seeking behaviors. Results showed that high eHEALS individuals were more likely to seek out online health information and were more likely to have higher NFC scores. NFC did not emerge as a moderator on the relationship between eHealth literacy and online health information seeking behaviors. Future directions are discussed, in particular, examining eHEALS as a construct of efficacy and further need to examine eHEALS with need for cognition in health communication research.

This research’s purposes were: 1 to analyze the students’ motivation; 2 to analyze the critical thinking and academic verification; 3 to analyze the information-seeking behavior. This study used quantitative approach through survey among 1125 respondents in nine clusters, i.e. Central, East, North, West, and South of Jakarta, Tangerang, Bekasi, Depok, and Bogor. Schools sampling based on "the best schools rank" by the government, while respondents have taken by accidental in each school. Construct of questionnaire included measurement of motivation, critical thinking and academic verification, and the information-seeking behavior at all. The results showed that the motivations of the use of Internet were dominated by habit to interact and be entertained while on the academic needs are still relatively small but increasing significantly. Students’ self-efficacy, performance and achievement goals tend to be high motives, however the science learning value, and learning environment stimulation were average low motives. High school students indicated that they think critically about the various things that become content primarily in social media but less critical of the academic information subjects. Unfortunately, high school students did not conducted academic verification on the data and information but students tend to do plagiarism.

    Full Text Available Academic researchers often need and re-use relevant information found after a period of time. This preliminary study used various methods, including experiments, interviews, search log analysis, sequential analysis, and observation to investigate characteristics of academic information finding and re-finding behavior. Overall, the participants in this study entered short queries either in finding or re-finding phases. Comparatively speaking, the participants entered greater number of queries, modified more queries, browsed more web pages, and stayed longer on web pages in the finding phase. On the other hand, in the re-finding phase, they utilized personal information management tools to re-find instead of finding again using search engine, such as checking browsing history; moreover, they tend to input less number of queries and stayed shorter on web pages. In short, the participants interacted more with the retrieval system during the finding phase, while they increased the use of personal information management tools in the re-finding phase. As to the contextual clues used in re-finding phase, the participants used less clues from the target itself, instead, they used indirect clues more often, especially location-related information. Based on the results of sequential analysis, the transition states in the re-finding phase was found to be more complex than those in the finding phase. Web information finding and re-finding behavior is an important and novel area of research. The preliminary results would benefit research on Web information re-finding behavior, and provide useful suggestions for developing personal academic information management systems.

    Full Text Available This study aims to examine the effect of individual behavioral change on the adoption of activity- based costing (ABC system and its usage, using Unified Theory of Accep-tance and Use of Technology (UTAUT and Information System Success Model. The sample involves 78 respondents who have positions as financial manager, controller manager, accounting manager, and production manager in mid-sized manufacturing companies in East java. The data were collected by survey method. This study used a Partial Least Square (PLS as the data analysis method. It was found that not all of the main UTAUT models were supported, because performance expectancy and effort expectancy have no effect on behavioral intention and use behavior to adopt ABC system. Whereas, social factors, information quality and facilitating conditions had a positive effect on behavioral intention and use behavior to adopt ABC system. The different results of this study with several previous studies are probably caused by the differences in the context of system, culture and characteristics of the sample. The implication of this study is not only to propose a theoretical framework for researches in future, but also useful for companies to optimize the use of ABC system that should be supported by top level and mid-level management and the readiness of the individu-als to accept the adoption of the ABC system.

    Full Text Available Background and aims. Parental acceptance and consent are important parameters in selecting the required behavior management technique during pediatric dental treatment. The present study sought to assess the effect of three different informing methods on the parental acceptance, consent and concern regarding the pharmacological and invasive behavior management techniques used in pediatric dentistry. Materials and methods. Ninety mothers of 3-6-year-old uncooperative children were selected and randomly assigned to three study groups. The parents in each group were initially asked to answer three questions related to their levels of ‘acceptance’, ‘consent’, and ‘concern’ toward the five behavior management techniques. Then, the information about the techniques was presented through a piece of writing in group I, verbal presentation in group II and showing a film in group III. At last, the parents answered the same three questions again. Score changes were analyzed by using ANOVA, correlations, Mann-Whitney U and Kruskal-Wallis methods. Results. There were no statistically significant differences in score changes of parental acceptance, consent and concern between the three groups, overall and in relation to each behaviour management technique (P > 0.05. Mothers with academic education revealed more statistically significant concern following presentation of information by film (P < 0.05. Conclusion. None of the presentation methods had a significant preference over the others; in selecting the behavioral management techniques, it is advisable to observe individual factors, such as the level of education of the mothers.

    Over 80% of people in methadone treatment smoke cigarettes, and existing smoking cessation interventions have been minimally effective. To develop an Information-Motivation-Behavioral Skills (IMB) Model of behavior change based smoking cessation intervention for methadone maintained smokers, we examined smoking cessation related IMB factors in this population. Current or former smokers in methadone treatment (n = 35) participated in focus groups. Ten methadone clinic counselors participated in an individual interview. A content analysis was conducted using deductive and inductive approaches. Commonly known IMB factors related to smoking cessation were described. These factors included: the health effects of smoking and treatment options for quitting (information); pregnancy and cost of cigarettes (motivators); and coping with emotions, finding social support, and pharmacotherapy adherence (behavioral skills). IMB factors specific to methadone maintained smokers were also described. These factors included: the relationship between quitting smoking and drug relapse (information), the belief that smoking is the same as using drugs (motivator); and coping with methadone clinic culture and applying skills used to quit drugs to quitting smoking (behavioral skills). IMB strengths and deficits varied by individual. Methadone maintained smokers could benefit from research on an IMB Model based smoking cessation intervention that is individualized, addresses IMB factors common among all smokers, and also addresses IMB factors unique to this population.

    Few studies have examined theoretically informed constructs related to hepatitis B (HBV) testing, and comparisons across studies are challenging due to lack of uniformity in constructs assessed. The present analysis examined relationships among Health Behavior Framework factors across four Asian American groups to advance the development of theory-based interventions for HBV testing in at-risk populations. Data were collected from 2007-2010 as part of baseline surveys during four intervention trials promoting HBV testing among Vietnamese-, Hmong-, Korean- and Cambodian-Americans (n = 1,735). Health Behavior Framework constructs assessed included: awareness of HBV, knowledge of transmission routes, perceived susceptibility, perceived severity, doctor recommendation, stigma of HBV infection, and perceived efficacy of testing. Within each group we assessed associations between our intermediate outcome of knowledge of HBV transmission and other constructs, to assess the concurrent validity of our model and instruments. While the absolute levels for Health Behavior Framework factors varied across groups, relationships between knowledge and other factors were generally consistent. This suggests similarities rather than differences with respect to posited drivers of HBV-related behavior. Our findings indicate that Health Behavior Framework constructs are applicable to diverse ethnic groups and provide preliminary evidence for the construct validity of the Health Behavior Framework.

    Web-based medical service (WBMS), a cooperative relationship between medical service and Internet technology, has been called one of the most innovative services of the 21st century. However, its business promotion and implementation in the medical industry have neither been expected nor executed. Few studies have explored this phenomenon from the viewpoint of inexperienced patients. The primary goal of this study was to explore whether technology attractiveness, medical creditability, and diversified medical information sources could increase users' behavior intention. This study explored the effectiveness of web-based medical service by using three situations to manipulate sources of medical information. A total of 150 questionnaires were collected from people who had never used WBMS before. Hierarchical regression was used to examine the mediation and moderated-mediation effects. Perceived ease of use (P=.002) and perceived usefulness (P=.001) significantly enhance behavior intentions. Medical credibility is a mediator (P=.03), but the relationship does not significantly differ under diverse manipulative information channels (P=.39). Medical credibility could explain the extra variation between technology attractiveness and behavior intention, but not significant under different moderating effect of medical information sources. ©Shan Huei Wang.

    Full Text Available Thesis is the research outcome that a graduate student spends most of his or her time and energies to achieve. Therefore, the research process of student’s thesis writing is an important topic to be investigated. The main purpose of this study is to explore graduate students’ information seeking behavior during the process of thesis writing. Ten graduate students in the field of communication were interviewed, and their information horizon maps as well as bibliographical references were analyzed also. Results showed that the library, as a formal channel, is the primary source for graduate students. The documents that they used most often were theses and dissertations, monographs, and journals. In addition to the formal channels, social network also played as a very important role in students’ research process. The networks even changed their information seeking behaviors in formal channels. Students reported several problems encountered in the research process, such as lacking of the background knowledge of the interdisciplinary, being unable to find out the core and relevant documents from the search results, etc. In conclusion, graduate students’ information seeking behavior changed at different stages in the research process.

    The purpose of this paper is to analyze Swedish households' willingness to increase their daily efforts to save electricity. The analysis builds on a broad theoretical framework, which embraces both economic and norm-based motivations in explaining household behavior. The paper pays particular attention to the role of information about the availability of different behavioral changes that can be undertaken at the household level. The empirical results are based on a postal survey that was sent out to 1200 Swedish households, and the econometric analysis is carried out within a so-called ordered probit framework. Our results indicate that costs, environmental attitudes and social interactions are all important determinants of electricity saving activities within Swedish households. We tested the hypothesis that information about available savings measures that is presented in a more concrete and specific way is more likely to affect (stated) behavior than is more general information, and the data collected support this notion. The paper ends by discussing some implications of these results for the design of future informative policy measures in the energy-efficiency field.

    The internet has become an important resource to help people search for online medication information. This study aims to report the prevalence and profile of Saudi online medication seeking behavior. Conducted via a web-based survey with Twitter participants between January-February, 2015, the primary outcome measures were the self-reported rates of using the internet to search for medication related information. A valid sample of 4847 participants was collected over the period of the study. Out of the total participants, 68.3% (n=3311) were found to seek online medication related information frequently. Most of the social media users were female 83.5% (n=2766). The majority of respondents 63.6% (n= 3081) used Google, followed by Twitter 28.7% (n= 1392), Snapchat 21%, (n=1019), WhatsApp 13.8% (n= 670), Instagram 11.4%, (n= 553), and Facebook 5.5 % (n= 267), with few searching YouTube 1.3% (n=65) to access online medication information. Findings indicate that the Saudi population actively uses the internet and social media to obtain medication information. Further studies are needed to explore the influence of the internet and social media on user perception, attitude, and behavior with the use of online medication information.

  6. The concepts of representation and information in explanatory theories of human behavior

    Directory of Open Access Journals (Sweden)

    Renato T. Ramos

    2014-09-01

    Full Text Available Focusing in experimental study of human behavior, this article discusses the concepts of information and mental representation aiming the integration of their biological, computational, and semantic aspects. Assuming that the objective of any communication process is ultimately to modify the receiver’s state, the term correlational information is proposed as a measure of how changes occurring in external world correlate with changes occurring inside an individual. Mental representations are conceptualized as a special case of information processing in which correlational information is received, recorded, but also modified by a complex emergent process of associating new elements. In humans, the acquisition of information and creation of mental representations occurs in a two-step process. First, a sufficiently complex brain structure is necessary to establishing internal states capable to co-vary with external events. Second, the validity or meaning of these representations must be gradually achieved by confronting them with the environment. This contextualization can be considered as part of the process of ascribing meaning to information and representations. The hypothesis introduced here is that the sophisticated psychological constructs classically associated with the concept of mental representation are essentially of the same nature of simple interactive behaviors. The capacity of generating elaborated mental phenomena like beliefs and desires emerges gradually during evolution and, in a given individual, by learning and social interaction.

  7. The influence of information processing goal pursuit on postdecision affect and behavioral intentions.

    Two important forces in human behavior are action and inaction. Although action and inaction are commonly associated with the presence and the absence of behavioral activity, they can also be represented as information processing goals. Action (inaction) goals influence decision effort and increase satisfaction with environments that are structured to allow for more (less) processing (Studies 1 and 2). This increased satisfaction can transfer to the decision (Study 3) and can increase the intent to perform a decision-congruent behavior (Studies 4 and 6). Finally, the author shows escalation of action and inaction goals when they are not achieved (Study 5) and rebound of the alternative goal when the focal goal is achieved (Study 6).

    Animals must rapidly and accurately process environmental information to produce the correct behavioral responses. Reactions to previously encountered as well as to novel but biologically important stimuli are equally important, and one understudied region in the insect brain plays a role in processing both types of stimuli. The lateral horn is a higher order processing center that mainly processes olfactory information and is linked via olfactory projection neurons to another higher order learning center, the mushroom body. This review focuses on the lateral horn of Drosophila where most functional studies have been performed. We discuss connectivity between the primary olfactory center, the antennal lobe, and the lateral horn and mushroom body. We also present evidence for the lateral horn playing roles in innate behavioral responses by encoding biological valence to novel odor cues and in learned responses to previously encountered odors by modulating neural activity within the mushroom body. We describe how these processes contribute to acceptance or avoidance of appropriate or inappropriate mates and food, as well as the identification of predators. The lateral horn is a sexually dimorphic and plastic region of the brain that modulates other regions of the brain to ensure that insects produce rapid and effective behavioral responses to both novel and learned stimuli, yet multiple gaps exist in our knowledge of this important center. We anticipate that future studies on olfactory processing, learning, and innate behavioral responses will include the lateral horn in their examinations, leading to a more comprehensive understanding of olfactory information relay and resulting behaviors.

    Studies examining whether genetic risk information about common, complex diseases can motivate individuals to improve health behaviors and advance planning have shown mixed results. Examining the influence of different study recruitment strategies may help reconcile inconsistencies. Secondary analyses were conducted on data from the REVEAL study, a series of randomized clinical trials examining the impact of genetic susceptibility testing for Alzheimer's disease (AD). We tested whether self-referred participants (SRPs) were more likely than actively recruited participants (ARPs) to report health behavior and advance planning changes after AD risk and APOE genotype disclosure. Of 795 participants with known recruitment status, 546 (69%) were self-referred and 249 (31%) had been actively recruited. SRPs were younger, less likely to identify as African American, had higher household incomes, and were more attentive to AD than ARPs (all P change to at least one health behavior 6 weeks and 12 months after genetic risk disclosure, nor in intentions to change at least one behavior in the future. However, interaction effects were observed where ε4-positive SRPs were more likely than ε4-negative SRPs to report changes specifically to mental activities (38% vs 19%, p change long-term care insurance among SRPs (20% vs 5%, p behavior changes than those who respond to genetic testing offers. These results demonstrate how the behavioral impact of genetic risk information may vary according to the models by which services are provided, and suggest that how participants are recruited into translational genomics research can influence findings.

  10. Oscillations, complex spatiotemporal behavior, and information transport in networks of excitatory and inhibitory neurons

    Various types of spatiotemporal behavior are described for two-dimensional networks of excitatory and inhibitory neurons with time delayed interactions. It is described how the network behaves as several structural parameters are varied, such as the number of neurons, the connectivity, and the values of synaptic weights. A transition from spatially uniform oscillations to spatiotemporal chaos via intermittentlike behavior is observed. The properties of spatiotemporally chaotic solutions are investigated by evaluating the largest positive Lyapunov exponent and the loss of correlation with distance. Finally, properties of information transport are evaluated during uniform oscillations and spatiotemporal chaos. It is shown that the diffusion coefficient increases significantly in the spatiotemporal phase similar to the increase of transport coefficients at the onset of fluid turbulence. It is proposed that such a property should be seen in other media, such as chemical turbulence or networks of oscillators. The possibility of measuring information transport from appropriate experiments is also discussed

    Evacuation from a smoke filled tunnel requires quick decision-making and swift action from the tunnel occupants. Technical installations such as emergency signage aim to guide tunnel occupants to the closest emergency exits. However, conflicting information may come from the behavior of other tunnel occupants. We examined if and how conflicting social information may affect evacuation in terms of delayed and/or inadequate evacuation decisions and behaviors. To this end, forty participants were repeatedly situated in a virtual reality smoke filled tunnel with an emergency exit visible to one side of the participants. Four social influence conditions were realized. In the control condition participants were alone in the tunnel, while in the other three experimental conditions a virtual agent (VA) was present. In the no-conflict condition, the VA moved to the emergency exit. In the active conflict condition, the VA moved in the opposite direction of the emergency exit. In the passive conflict condition, the VA stayed passive. Participants were less likely to move to the emergency exit in the conflict conditions compared to the no-conflict condition. Pre-movement and movement times in the passive conflict condition were significantly delayed compared to all other conditions. Participants moved the longest distances in the passive conflict condition. These results support the hypothesis that social influence affects evacuation behavior, especially passive behavior of others can thwart an evacuation to safety.

    Little is known about how actual use of Internet health-related information is associated with health or health-related behavior. Using a nationally representative sample of 34,525 from 2012, this study examined the demographics of users of Internet health-related information (users), reports estimates of association with several health and behavioral outcomes adjusting for demographic factors, and analyzed the sample by education level, race, gender, and age. Analysis of a large nationally representative sample shows evidence that users of health-related information (users) on the Internet are younger, more educated, more likely to be insured, more likely to be female, and less likely to be African American. After adjusting for demographic differences, users are more likely to have been diagnosed with hypertension, cancer, stroke, and high cholesterol, but no evidence of current hypertension, weight-related issues, or being in fair or poor health. Users are less likely to smoke and among smokers are more likely to attempt quitting. Users are more likely to exercise, get a flu shot, pap smear, mammogram, HIV test, colon cancer screening, blood pressure check, and cholesterol check, but likely to be heavy drinkers. With few exceptions, results appear robust across gender, age groups, level of education, and ethnicity. Use is generally positively associated with prior diagnosis for several conditions and behaviors related to improved health, but I find no relationship with existing health status. The association between use of health-related Internet information and health-related behavior seems robust across levels of education, age, gender, and race.

    Web 2.0 has become a leading health communication platform and will continue to attract young users; therefore, the objective of this study was to understand the impact of Web 2.0 on health information seeking behavior among university students in Bangladesh. A random sample of adults (n = 199, mean 23.75 years, SD 2.87) participated in a cross-sectional, a survey that included the eHealth literacy scale (eHEALS) assessed use of Web 2.0 for health information. Collected data were analyzed using a descriptive statistical method and t-tests. Finally logistic regression analyses were conducted to determine associations between sociodemographic, social determinants, and use of Web 2.0 for seeking and sharing health information. Almost 74% of older Web 2.0 users (147/199, 73.9%) reported using popular Web 2.0 websites, such as Facebook and Twitter, to find and share health information. Current study support that current Web-based health information seeking and sharing behaviors influence health-related decision making.

    This paper assesses the effectiveness of aquifer monitoring information in achieving more sustainable use of a groundwater resource in the absence of management policy. Groundwater user behavior in the face of an irreversible contamination threat is studied by applying methods of experimental economics to scenarios that combine a physics-based, spatially explicit, numerical groundwater model with different representations of information about an aquifer and its risk of contamination. The results suggest that the threat of catastrophic contamination affects pumping decisions: pumping is significantly reduced in experiments where contamination is possible compared to those where pumping cost is the only factor discouraging groundwater use. The level of information about the state of the aquifer also affects extraction behavior. Pumping rates differ when information that synthesizes data on aquifer conditions (a "risk gauge") is provided, despite invariant underlying economic incentives, and this result does not depend on whether the risk information is location-specific or from a whole aquifer perspective. Interestingly, users increase pumping when the risk gauge signals good aquifer status compared to a no-gauge treatment. When the gauge suggests impending contamination, however, pumping declines significantly, resulting in a lower probability of contamination. The study suggests that providing relatively simple aquifer condition guidance derived from monitoring data can lead to more sustainable use of groundwater resources.

  20. Differential use of sensory information in sexual behavior as a function of gender.

    Olfactory information is critical to mammalian sexual behavior. Based on parental investment theory the relative importance of olfaction compared with vision, touch, and hearing should be different for human males and females. In particular, because of its link to immunological profile and offspring viability, odor should be a more important determinant of sexual choice and arousal for females than for males. To test this hypothesis a questionnaire was developed and administered to 332 adults (166 males, 166 females). Subjects used a 1-7 scale to indicate how much they agreed with a series of statements concerning the importance of olfactory, visual, auditory, and tactile information for their sexual responsivity. The data reveal that males rated visual and olfactory information as being equally important for selecting a lover, while females considered olfactory information to be the single most important variable in mate choice. Additionally, when considering sexual activity, females singled out body odor from all other sensory experiences as most able to negatively affect desire, while males regarded odors as much more neutral stimuli for sexual arousal. The present results support recent findings in mice and humans concerning the relation of female preferences in body odor and major histocompatibility complex (MHC) compatibility and can be explained by an evolutionary analysis of sex differences in reproductive strategies. This work represents the first direct examination of the role of different forms of sensory information in human sexual behavior.

    Full Text Available Timely access to quality healthcare information during an outbreak plays an important role in curtailing its spread. The aim of this study was to investigate the information needs and seeking behavior of the general public in Singapore during the H1N1 pandemic. A pre-tested questionnaire was used for data collection. The convenience snowball sampling method was used and 260 working adults and tertiary-level students participated in this study. The most crucial information needs of a majority of the participants were: symptoms of H1N1, causes of the infection, preventive measures, and possible treatments. Data analysis also revealed that mass media such as television, newspapers, and radio were most frequently used for seeking the needed information. The use of human information sources was also quite high while only a small number of the respondents accessed online news and healthcare websites. About three-quarters of the participants indicated that the gathered information helped them to stay vigilant and take necessary precautionary measures. A major problem identified by the participants in using H1N1 information was the lack of understanding of certain terms used in public communications. This paper suggests certain measures for strengthening health information communication during future outbreaks.

    Background One in twenty-five Ugandan adolescents is HIV positive. Purpose Examine the impact of an Internet-based HIV prevention program on Information-Motivation-Behavior Skills Model-related constructs. Methods Three hundred and sixty-six sexually experienced and inexperienced students 12-18+ years-old in Mbarara, Uganda were randomly assigned to: the five-lesson CyberSenga program or treatment-as-usual. Half of the intervention participants were further randomized to a booster session. Assessments were collected at three and six months post-baseline. Results Participants’ HIV-related information improved over time at a greater rate for the intervention groups compared to the control group. Motivation for condom use changed to a greater degree over time for the intervention group – especially those in the intervention+booster group - compared to the control group. Behavioral skills for condom use, and motivation and behavioral skills for abstinence were statistically similar over time for both groups. Conclusions CyberSenga improves HIV preventive information and motivation to use condoms. PMID:25633626

    Full Text Available Immigrants are generally perceived to be information poor, meaning they face major challenges with finding and using greatly needed everyday information. However, little research exists from an information behaviour perspective as differences in language, culture, and other factors such as access make immigrants a difficult population to study. We explored the everyday information behaviour and information grounds of migrant Hispanic farm workers through field observation and interviews with users, non-users, and staff of community technology centres in a major agricultural area. Findings suggest that personal networks having various levels of credibility were used more readily than any other type of information source. Credibility and use of various sources seemed to relate to personal status as well as interest in information.

    The Internet provides a platform to access health information and support self-management by consumers with chronic health conditions. Despite recognized barriers to accessing Web-based health information, there is a lack of research quantitatively exploring whether consumers report difficulty finding desired health information on the Internet and whether these consumers would like assistance (ie, navigational needs). Understanding navigational needs can provide a basis for interventions guiding consumers to quality Web-based health resources. We aimed to (1) estimate the proportion of consumers with navigational needs among seekers of Web-based health information with chronic health conditions, (2) describe Web-based health information-seeking behaviors, level of patient activation, and level of eHealth literacy among consumers with navigational needs, and (3) explore variables predicting navigational needs. A questionnaire was developed based on findings from a qualitative study on Web-based health information-seeking behaviors and navigational needs. This questionnaire also incorporated the eHealth Literacy Scale (eHEALS; a measure of self-perceived eHealth literacy) and PAM-13 (a measure of patient activation). The target population was consumers of Web-based health information with chronic health conditions. We surveyed a sample of 400 Australian adults, with recruitment coordinated by Qualtrics. This sample size was required to estimate the proportion of consumers identified with navigational needs with a precision of 4.9% either side of the true population value, with 95% confidence. A subsample was invited to retake the survey after 2 weeks to assess the test-retest reliability of the eHEALS and PAM-13. Of 514 individuals who met our eligibility criteria, 400 (77.8%) completed the questionnaire and 43 participants completed the retest. Approximately half (51.3%; 95% CI 46.4-56.2) of the population was identified with navigational needs. Participants with

    Considered a public health issue, the prevalence and severity of poor mental well-being on college campuses has continued to rise. While many college campuses offer mental health counseling services, and utilization rates are increasing, their proportional usage is low especially among males, who often deal with poor mental well-being by adopting unhealthy coping strategies. The purpose of this study was to use the Information-Motivation-Behavioral Skills (IMB) model to assess the relationship between the determinants as factors that may impact help-seeking behaviors in a large sample ( n = 1,242) of male college students. Employing a cross-sectional study design, a 71-item online survey assessed information via total mental health literacy (MHL), motivation via attitudes toward mental health and subjective norms regarding mental health, and behavioral skills via intentions regarding help-seeking behaviors, and stigma. Results revealed correlations between information and motivation ( r = .363, p < .01), information and behavioral skills ( r = .166, p < .01), and motivation and behavioral skills ( r = .399, p < .01). Multiple regression was used to determine stigma is a mediator for all relationships. These findings represent an opportunity to take a public health approach to male mental health through developing multilayered interventions that address information, motivation, behavioral skills, and stigma.

    Information foraging connects optimal foraging theory in ecology with how humans search for information. The theory suggests that, following an information scent, the information seeker must optimize the tradeoff between exploration by repeated steps in the search space vs. exploitation, using the resources encountered. We conjecture that this tradeoff characterizes how a user deals with uncertainty and its two aspects, risk and ambiguity in economic theory. Risk is related to the perceived quality of the actually visited patch of information, and can be reduced by exploiting and understanding the patch to a better extent. Ambiguity, on the other hand, is the opportunity cost of having higher quality patches elsewhere in the search space. The aforementioned tradeoff depends on many attributes, including traits of the user: at the two extreme ends of the spectrum, analytic and wholistic searchers employ entirely different strategies. The former type focuses on exploitation first, interspersed with bouts of exploration, whereas the latter type prefers to explore the search space first and consume later. Our findings from an eye-tracking study of experts' interactions with novel search interfaces in the biomedical domain suggest that user traits of cognitive styles and perceived search task difficulty are significantly correlated with eye gaze and search behavior. We also demonstrate that perceived risk shifts the balance between exploration and exploitation in either type of users, tilting it against vs. in favor of ambiguity minimization. Since the pattern of behavior in information foraging is quintessentially sequential, risk and ambiguity minimization cannot happen simultaneously, leading to a fundamental limit on how good such a tradeoff can be. This in turn connects information seeking with the emergent field of quantum decision theory.

    Full Text Available Objectives: Reports in autism spectrum disorders (ASD of a minicolumnopathy with consequent deficits of lateral inhibition help explain observed behavioral and executive dysfunctions. We propose that neuromodulation based on rTMS will enhance lateral inhibition through activation of inhibitory double bouquet interneurons and will be accompanied by improvements in the prefrontal executive functions. Methods: The current study used ERPs in a visual oddball task with illusory figures. We compared clinical, behavioral and electrocortical outcomes in 2 groups of children with autism (TMS, wait-list group [WTL]. We predicted that 18 session long course in autistic patients will have better behavioral and ERP outcomes as compared to age- and IQ-matched wait-list group. We used 18 sessions of 1Hz rTMS applied over the dorso-lateral prefrontal cortex in 27 individuals with ASD diagnosis. The WTL group was comprised of 27 age-matched ASD subjects. Results: Post-TMS evaluations showed decreased irritability and hyperactivity and decreased stereotypic behaviors. Following rTMS we found decreased amplitude and prolonged latency in the fronto-central ERPs to non-targets in the TMS group. These ERP changes along with increased centro-parietal ERPs to targets are indicative of more efficient processing of information post-TMS. Another finding was increased magnitude of error-related negativity (ERN during commission errors. We calculated normative post-error reaction time (RT slowing response in both groups and found that rTMS was accompanied by post-error RT slowing and higher accuracy of responses, whereas the WTL group kept on showing typical for ASD post-error RT speeding and had higher error rate. Conclusion: Results from our study indicate that rTMS improves executive functioning in ASD as evidenced by normalization of ERP responses and behavioral reactions during executive function test, and also by improvements in clinical behavioral evaluations.

    We used a valid questionnaire to survey Iranian nurses' seeking information behavior and their confidence on different information sources. The frequently used sources were Internet" and "personal experiences" (54.8% and 48.2% respectively). "English medical journals" (61.9%) and "English textbooks" (41.3%) were the least frequently used sources. Nurses felt high confidence in sources such as "International instructions/guidelines" (58.6%) and "English medical textbooks" (50.4%). The main reasons for selecting sources were easy accessibility, being up to date and reliability. Google, Pubmed and Up to Date were the most used electronic sources. In addition, there were differences in terms of using some of these resources and nurse' age and gender. In developing information sources for nurses, factors such as reliability level, availability, and updatedness of resources should be more emphasized.

    One tradition in research for explaining aggression and antisocial behavior has focused on social information processing (SIP). Aggression and antisocial behavior have also been studied from the perspective of executive functions (EFs), the higher-order cognitive abilities that affect other cognitive processes, such as social cognitive processes. The main goal of the present study is to provide insight into the relation between EFs and SIP in adolescents with severe behavior problems. Because of the hierarchical relation between EFs and SIP, we examined EFs as predictors of SIP. We hypothesized that, first, focused attention predicts encoding and interpretation, second, inhibition predicts interpretation, response generation, evaluation, and selection, and third, working memory predicts response generation and selection. The participants consisted of 94 respondents living in residential facilities aged 12-20 years, all showing behavior problems in the clinical range according to care staff. EFs were assessed using subtests from the Amsterdam Neuropsychological Test battery. Focused attention was measured by the Flanker task, inhibition by the GoNoGo task, and working memory by the Visual Spatial Sequencing task. SIP was measured by video vignettes and a structured interview. The results indicate that positive evaluation of aggressive responses is predicted by impaired inhibition and selection of aggressive responses by a combination of impaired focused attention and inhibition. It is concluded that different components of EFs as higher-order cognitive abilities affect SIP.

    Few studies have focused on the neuroanatomy of aggressive behavior in children younger than 10 years. Here, we explored the neuroanatomical correlates of aggression in a population-based sample of 6- to 9-year-old children using a multiple-informant approach. Magnetic resonance (MR) scans were acquired from 566 children from the Generation R study who participated in the Berkeley Puppet Interview and whose parents had completed the Child Behavior Checklist. Linear regression analyses were used to examine associations between aggression and amygdala and hippocampal volume. We performed surface-based analyses to study the association between aggression and cortical thickness, surface area, and gyrification. Aggressive behavior was associated with smaller amygdala (p left precentral cortex (p right inferior parietal, supramarginal, and postcentral cortex (p Gender moderated the association between aggression and cortical thickness in the right medial posterior cortex (p = .001) and the right prefrontal cortex (p right precentral, postcentral, frontal, and parietal cortex (p = .01). Moreover, aggression was associated with decreased gyrification in the right occipital and parietal cortex (p = .02). We found novel evidence that childhood aggressive behavior is related to decreased amygdala volume, decreased sensorimotor cortical thickness, and decreased global right hemisphere gyrification. Aggression is related to cortical thickness in regions associated with the default mode network, with negative associations in boys and positive associations in girls.

    Social determinants, such as socioeconomic status (SES) and race/ethnicity are linked to striking health disparities across the cancer continuum. One important mechanism linking social determinants and health disparities may be communication inequalities that are caused by differences in accessing, processing and utilizing cancer information. In this context, we examined health information-seeking/avoidance as a potential mediator between social determinants and self-rated health (SRH) status among cancer survivors. Data came from the 2008 well-informed, thriving and surviving (WITS) study of post-treatment cancer survivors (n=501). We examined the mediating effect of health communication-related behavior between SES and disparities in SRH. The likelihood of belonging to the Low SRH group was higher among patients who had avoided health information and whose family members had not sought health information on behalf of the survivor, those in the lowest household income bracket, and those who had high school or less education after adjusting for potential confounders. Differences in SRH among cancer survivors are associated with SES as well as communication inequalities. It is necessary to provide a supportive environment in which health information is made available if disparities in health-related quality of life among cancer survivors are to be reduced.

    Full Text Available The purpose of this paper is to explore the factors influencing behaviors of information sharing in complex organizations. Evaluation of the previous studies on provision of information turnover process and the role of organizational culture in competitive intelligence of business environment in Latvia indicated the trends that employees of Latvian enterprises lack incentive to share information. Tasks of the study were to research the basis of the review of scientific sources and study aspects influencing habits of information sharing in complex organizations. For this particular study, the focus group is selected as the most appropriate data collection method for high-quality research. To find out individuals' opinions and attitudes two focus group discussions were carried out. Members from various industries and with different employment period were included in discussion groups. In aggregate, opinions of the employees from 41 different companies were summarized regarding the aspects affecting the process of information sharing in organizations. Results of researches show that that influence the sharing of information are closely related to the values: interpersonal trust, organizational trust, and organizational identification, support, fairness etc. Results of discussions showed that it is important for a manager to be aware of the factors affecting the performance of the organization. To identify the need for changes, a manager should follow events in the environment and analyze the extent, to which they affect the performance of the organization. Complexity science suggests that maturity to changes emerges when the system is far from balance, but the tension makes to accept changes.

  15. The Seven Deadly Tensions of Health-Related Human Information Behavior

    2015-08-01

    Full Text Available Tensions are a ubiquitous feature of social life and are manifested in a number of particular forms: contradictory logics, competing demands, clashes of ideas, contradictions, dialectics, irony, paradoxes, and/or dilemmas. This essay aims to explore in detail tensions surrounding seven common findings of the information seeking literature relating to: interpersonal communication, accessibility, level of skill, individual preferences, psychological limits, inertia, and costs. Our incomplete understanding of these tensions can lead us to suggest resolutions that do not recognize their underlying dualities. Human information behavior stands at the intersection of many important theoretical and policy issues (e.g., personalized medicine. Policy makers need to be more attuned to these basic tensions of information seeking recognizing the real human limits they represent to informing the public. So, even if you build a great information system, people will not necessarily use it because of the force of these underlying tensions. While rationality rules systems, irrationality rules people. The proliferation of navigator roles over the last several years is actually a hopeful sign: recognition that people need a human interface to inform them about our ever more complex health care systems.

    Objectives: The eighteen-month evaluation of a clinical librarian project (October 2003–March 2005) conducted in North Wales, United Kingdom (UK) assessed the benefits of clinical librarian support to clinical teams, the impact of mediated searching services, and the effectiveness of information skills training, including journal club support. Methods: The evaluation assessed changes in teams' information-seeking behavior and their willingness to delegate searching to a clinical librarian. Baseline (n = 69 responses, 73% response rate) and final questionnaire (n = 57, 77% response rate) surveys were complemented by telephone and face-to-face interviews (n = 33) among 3 sites served. Those attending information skills training sessions (n = 130) completed evaluations at the session and were surveyed 1 month after training (n = 24 questionnaire responses, n = 12 interviews). Results: Health professionals in clinical teams reported that they were more willing to undertake their own searching, but also more willing to delegate some literature searching, than at the start of the project. The extent of change depended on the team and the type of information required. Information skills training was particularly effective when organized around journal clubs. Conclusions: Collaboration with a clinical librarian increased clinician willingness to seek information. Clinical librarian services should leverage structured training opportunities such as journal clubs. PMID:17252062

Bilgi davranışı ile ilgili yapılan ilk çalışmaların sistem odaklı olduğu, amacının sistemin sorunlarını çözmek olduğu, ayrıca konuya bilgi merkezleri açısından yaklaşıldığı bilinmektedir. Ancak 1980 sonrası, konu kullanıcı/birey açısından ele alınmış, son on yılda da akademik ilgi, bireysel bilgi davranışından ortak bilgi davranışına yönelmiştir. Ortak bilgi davranışı, ekipler/topluluklar içindeki ortak aklı işbirliği ile ortaya çıkartmak suretiyle optimum kararların alınmasına yardımcı olmaktadır. Konu ile ilgili gerek teorik gerekse teknik çalışmalar halen ön-paradigma aşamasındadır ve sınırlı sayıda da olsa modeller geliştirilmektedir. Ortak bilgi davranışında, ortak zemin, bağlam, farkındalık, güven gibi faktörler ve bunların davranış üzerindeki etkileri araştırılmaktadır. İnsan- makine arasındaki etkileşim senaryolarının (örneğin insan-insan, insan-makine, insan-makine-insan vb. çeşitliliği, konunun sosyal ve/veya teknik açılardan ele alınmasını gerektirmekte, bu ise kavramsallaştırmada zorluklara neden olmaktadır.

    Over the last decade, the Internet has become an important source of health-related information for a wide range of users worldwide. Yet, little is known about the personal characteristics of Egyptian Internet users who search for online health information (OHI). The aim of the study was to identify the personal characteristics of Egyptian OHI seekers and to determine any associations between their personal characteristics and their health information-seeking behavior.  This cross-sectional questionnaire study was conducted from June to October 2015. A Web-based questionnaire was sent to Egyptian users aged 18 years and older (N=1400) of a popular Arabic-language health information website. The questionnaire included (1) demographic characteristics; (2) self-reported general health status; and (3) OHI-seeking behavior that included frequency of use, different topics sought, and self-reported impact of obtained OHI on health behaviors. Data were analyzed using descriptive statistics and multiple regression analysis. A total of 490 participants completed the electronic questionnaire with a response rate equivalent to 35.0% (490/1400). Regarding personal characteristics, 57.1% (280/490) of participants were females, 63.4% (311/490) had a university level qualification, and 37.1% (182/490) had a chronic health problem. The most commonly sought OHI by the participants was nutrition-related. Results of the multiple regression analysis showed that 31.0% of the variance in frequency of seeking OHI among Egyptian adults can be predicted by personal characteristics. Participants who sought OHI more frequently were likely to be female, of younger age, had higher education levels, and good self-reported general health. Our results provide insights into personal characteristics and OHI-seeking behaviors of Egyptian OHI users. This will contribute to better recognize their needs, highlight ways to increase the availability of appropriate OHI, and may lead to the

  19. How could disclosing incidental information from whole-genome sequencing affect patient behavior?

    Christensen, Kurt D; Green, Robert C

    2013-06-01

    In this article, we argue that disclosure of incidental findings from whole-genome sequencing has the potential to motivate individuals to change health behaviors through psychological mechanisms that differ from typical risk assessment interventions. Their ability to do so, however, is likely to be highly contingent upon the nature of the incidental findings and how they are disclosed, the context of the disclosure and the characteristics of the patient. Moreover, clinicians need to be aware that behavioral responses may occur in unanticipated ways. This article argues for commentators and policy makers to take a cautious but optimistic perspective while empirical evidence is collected through ongoing research involving whole-genome sequencing and the disclosure of incidental information.

    In this contribution an empirical approach is used to gain more insight into the relationship between neuroscience and criminal law. The focus is on case law in the Netherlands. Neuroscientific information and techniques have found their way into the courts of the Netherlands. Furthermore, following an Italian case in which a mentally ill offender received a penalty reduction in part because of a 'genetic vulnerability for impulsive aggression', the expectation was expressed that such 'genetic defenses' would appear in the Netherlands too. To assess how neuroscientific and behavioral genetic information are used in criminal justice practice in the Netherlands, we systematically collect Dutch criminal cases in which neuroscientific or behavioral genetic information is introduced. Data and case law examples are presented and discussed. Although cases are diverse, several themes appear, such as prefrontal brain damage in relation to criminal responsibility and recidivism risk, and divergent views of the implications of neurobiological knowledge about addiction for judging criminal responsibility. Whereas in the international 'neurolaw literature' the emphasis is often on imaging techniques, the Dutch findings also illustrate the role of neuropsychological methods in criminal cases. Finally, there appears to be a clear need of practice oriented instruments and guidelines.

    Social network sites (SNSs) such as Facebook function as both venues for reconnecting with associates from a user's past and sources of social information about them. Yet, little is known about what factors influence the initial decision to reconnect with a past associate. This oversight is significant given that SNSs and other platforms provide an abundance of social information that may be utilized for reaching such decisions. The present study investigated the links among relational reconnection, information seeking (IS) behavior, and individual- and relationship-level factors in user decisions to reconnect on Facebook. A national survey of 244 Facebook users reported on their most recent experience of receiving a friend request from someone with whom they had been out of contact for an extended period. Results indicated that uncertainty about the potential reconnection partner and forecast about the reconnection's potential reward level significantly predicted IS behavior (passive on both target and mutual friends' SNS pages as well as active). However, the emergence of their two-way interaction revealed that the forecasts moderated the IS-uncertainty link on three of the strategies (extractive, both passive approaches). Moreover, social anxiety, sociability, uncertainty about the partner, the forecast about the reconnection's reward level, and extractive and passive (target SNS pages) strategies significantly predicted user decisions to reconnect. Future directions for research on relational reconnection on SNSs are offered.

    The proliferation of both manufacturer-controlled and independent medication-related websites has aroused concern among consumers and policy-makers concerning the trustworthiness of Web-based drug information. The authors examine consumers' trust in on-line prescription drug information and its influence on information search behavior. The study design involves a retrospective analysis of data from a 1998 national survey. The findings reveal that trust in drug information from traditional media sources such as television and newspapers transfers to the domain of the Internet. Furthermore, a greater trust in on-line prescription drug information stimulates utilization of the Internet for information search after exposure to prescription drug advertising.

    Full Text Available This study aimed to explore and analyze uncertainty in the information seeking behavior among the students of Kerman University of Medical Sciences (KUMS based on Kuhlthau Information Search Process Model. This is an applied research. Data gathered using questionnaire. Research population included 1075 students from all graduate students of KUMS in M.Sc. and Ph.D. grades. The sample size estimated 263 people .The studied students had relatively similar senses as reported by Kuhlthau in her information search process model. Among demographic variables, only gender affected the presentation stage. Women had better performance in the presentation stage. Ph.D. students performed better than master students when selecting their research topics. These two groups had no clear differences in other stages. Students with previous experience in research activities had better performance in title selection, literature exploration and presentation stages and also had lower uncertainty. The students’ performance decreased in different stages as their ages increased. The effect of individuals’ age on their performance was considerable in the stages of literature exploration and result presentation. The graduate students of KUMS follow the same stages as Kuhlthau information search process model and have similar feelings with that. Uncertainty was felt in the different stages of information search by graduate students of KUMS. The factors like age, gender, level of education and previous experience were effective in some stages on decrease or increase of uncertainty.

    In response to changing internal and external situations, we always need to adapt our behavior based on previous experiences, particularly, acquired stimulus-outcome information. The orbitofrontal cortex (OFC), a prefrontal cortical region, is critical for this type of decision-making. The current understanding of the fundamental functions of the OFC has been reviewed by introducing, as an example, how the OFC contributes to the processing of uncertain rewards. Furthermore, the importance of revealing context and temporally specific causal roles of neural circuits including the OFC in decision-making, as well as the techniques to achieve the goal, have been discussed.

    During the SPIE 2012 conference, panelists convened to discuss "Real world issues and challenges in Human Social/Cultural/Behavioral modeling with Applications to Information Fusion." Each panelist presented their current trends and issues. The panel had agreement on advanced situation modeling, working with users for situation awareness and sense-making, and HSCB context modeling in focusing research activities. Each panelist added different perspectives based on the domain of interest such as physical, cyber, and social attacks from which estimates and projections can be forecasted. Also, additional techniques were addressed such as interest graphs, network modeling, and variable length Markov Models. This paper summarizes the panelists discussions to highlight the common themes and the related contrasting approaches to the domains in which HSCB applies to information fusion applications.

    This study is based on a survey designed to determine the Information Seeking Behavior (ISB) of Astronomy and Astrophysics users in India. The main objective of the study is to determine the sources consulted and the general pattern of the information-gathering system of users and the impact of Information and Communication Technology (ICT) on the Astronomy and Astrophysics user's Information Seeking Behavior. It examines various Information and Communication Technology-based resources and methods of access and use. A descriptive sample stratified method has been used and data was collected using a questionnaire as the main tool. The response rate was 72%. Descriptive statistics were also employed and data have been presented in tables and graphs. The study is supported by earlier studies. It shows that Astronomy and Astrophysics users have developed a unique Information Seeking Behavior to carry out their education and research. The vast majority of respondents reported that more information is available from a variety of e-resources. Consequently, they are able to devote more time to seek out relevant information in the current Information and Communication Technology scenario. The study also indicates that respondents use a variety of information resources including e-resources for teaching and research. Books and online databases such as the NASA Astrophysics Data System (ADS) were considered more important as formal sources of information. E-mail and face-to-face communications are used extensively by users as informal sources of information. It also reveals that despite the presence of electronic sources, Astronomy and Astrophysics users are still using printed materials. This study should to help to improve various Information and Communication Technology-based services. It also suggests that GOI should adopt Information and Communication Technology-based Information Centers and Libraries services and recommends a network-based model for Astronomy and

    Within an ecosystem, components of the atmosphere, vegetation, and the root-soil system participate in forcing and feedback reactions at varying time scales and intensities. These interactions constitute a complex network that exhibits behavioral shifts due to perturbations ranging from weather events to long-term drought or land use change. However, it is challenging to characterize this shifting network due to multiple drivers, non-linear interactions, and synchronization due to feedback. To overcome these issues, we implement a process network approach where eco-hydrologic time-series variables are nodes and information measures are links. We introduce a Temporal Information Partition Network (TIPNet) framework in which multivariate lagged mutual information between source and target nodes is decomposed into synergistic, redundant, and unique components, each of which reveals different aspects of interactions within the network. We use methods to compute information measures given as few as 200 data points to construct TIPNets based on 1-minute weather station data (radiation Rg, air temperature Ta, wind speed WS, relative humidity RH, precipitation PPT, and leaf wetness LWet) from Central Illinois during the growing season of 2015. We assess temporal shifts in network behavior for various weather conditions and over the growing season. We find that wet time periods are associated with complex and synergistic network structures compared to dry conditions, and that seasonal network patterns reveal responses to vegetation growth and rainfall trends. This framework is applicable to study a broad range of complex systems composed of multiple interacting components, and may aid process understanding, model improvement, and resilience and vulnerability assessments.

    This study aimed to identify and compare the demographic, health behavior, health status, and social media use correlates of online health-seeking behaviors among men and women. Cross-sectional self-report data were collected from 1,289 Australian adults participating in the Queensland Social Survey. Logistic regression analyses were used to identify the correlates of online health information seeking for men and women. Differences in the strength of the relation of these correlates were tested using equality of regression coefficient tests. For both genders, the two strongest correlates were social media use (men: odds ratio [OR] = 2.57, 95% confidence interval [CI: 1.78, 3.71]; women: OR = 2.93, 95% CI [1.92, 4.45]) and having a university education (men: OR = 3.63, 95% CI [2.37, 5.56]; women: OR = 2.74, 95% CI [1.66, 4.51]). Not being a smoker and being of younger age were also associated with online health information seeking for both men and women. Reporting poor health and the presence of two chronic diseases were positively associated with online health seeking for women only. Correlates of help seeking online among men and women were generally similar, with exception of health status. Results suggest that similar groups of men and women are likely to access health information online for primary prevention purposes, and additionally that women experiencing poor health are more likely to seek health information online than women who are relatively well. These findings are useful for analyzing the potential reach of online health initiatives targeting both men and women. © The Author(s) 2016.

    The aim of this study is to clarify the health behavior of elderly people engaged in agriculture and information communication technology (ICT). The participants were 61 people engaged in agriculture in conjunction with ICT systems (group A), and 49 people not engaged in this (group B) from among the people aged 65 years or over in village C, both living located in a mountain areas. Data were collected from August 2009 to June 2011 in two stages: interviews to members of group A through home visits, and a group survey of groups A and B through questionnaires. The results of the study were as follows: 1) members of group A lived with feelings of attachment to the land to which they were accustomed and showed gratitude to their ancestors; 2) in group A, the desire of participants to continue their life was sufficient motivation to look after their own health and maintain independence; and 3) they provided a new challenge and a sense of achievement. The results suggest that the health behavior in group A was behavior adopted voluntarily in order to maintain an independent lifestyle supported by working, and it is likely to be linked to the preservation of health.

    Sonification is an open-ended design task to construct sound informing a listener of data. Understanding application context is critical for shaping design requirements for data translation into sound. Sonification requires methodology to maintain reproducibility when data sources exhibit non-linear properties of self-organization and emergent behavior. This research formalizes interactive sonification in an extensible model to support reproducibility when data exhibits emergent behavior. In the absence of sonification theory, extensibility demonstrates relevant methods across case studies. The interactive sonification framework foregrounds three factors: reproducible system implementation for generating sonification; interactive mechanisms enhancing a listener's multisensory observations; and reproducible data from models that characterize emergent behavior. Supramodal attention research suggests interactive exploration with auditory feedback can generate context for recognizing irregular patterns and transient dynamics. The sonification framework provides circular causality as a signal pathway for modeling a listener interacting with emergent behavior. The extensible sonification model adopts a data acquisition pathway to formalize functional symmetry across three subsystems: Experimental Data Source, Sound Generation, and Guided Exploration. To differentiate time criticality and dimensionality of emerging dynamics, tuning functions are applied between subsystems to maintain scale and symmetry of concurrent processes and temporal dynamics. Tuning functions accommodate sonification design strategies that yield order parameter values to render emerging patterns discoverable as well as rehearsable, to reproduce desired instances for clinical listeners. Case studies are implemented with two computational models, Chua's circuit and Swarm Chemistry social agent simulation, generating data in real-time that exhibits emergent behavior.

  13. Values determine the (ineffectiveness of informational interventions in promoting pro-environmental behavior.

    Directory of Open Access Journals (Sweden)

    Jan Willem Bolderdijk

    Full Text Available Informational interventions (e.g., awareness campaigns, carbon footprint calculators are built on the assumption that informing the public about the environmental consequences of their actions should result in increased pro-environmental intentions and behavior. However, empirical support for this reasoning is mixed. In this paper, we argue that informational interventions may succeed in improving people's knowledge about the negative environmental consequences of one's actions, but this knowledge will not gain motivational force if people do not consider protecting the environment an important personal value. In an experiment, we measured individual differences in value priorities, and either presented participants a movie clip that portrayed the negative environmental consequences of using bottled water, or a control movie. As predicted, we found that the environmental movie improved recipients' knowledge of the negative environmental impact of bottled water, but this knowledge only resulted in concomitant changes in intentions and acceptability of related policies among participants who strongly endorsed biospheric (i.e. environmental values, while having no effect on those who care less about the environment. Interestingly, the results suggest that although informational interventions are perhaps not always successful in directly affecting less environmentally-conscious recipients, they could still have beneficial effects, because they make those who strongly care about the environment more inclined to act on their values.

    Full Text Available Technological expansion and the changing way individuals gain access to information has deeply impacted the structure of libraries – physically as well as conceptually. A new generation of digital services platforms for libraries is emerging, designed to provide a more comprehensive  approach  to  the  management  and  access  to  all  formats  of  library  materials. Despite the modernization of libraries and their adaption to the digital age, the library still hold a critical role within community to serve its users, continuing to be beacons of information sharing, learning, and entertainment even amidst tight fiscal times.  As one of the leading university in Indonesia, Bogor Agricultural University Library must find solutions to new challenges, overhaul many of their entrenched business processes, and foster systems that engage students.  This study examined the information seeking behavior of the digital native and digital immigrant students of Bogor Agricultural University, in order to remind the library that there are some changes happened in its users and to recommend the new services should be taken by the library. The similarities and differences in seeking information of those two group students were discussed.

    This study examined the information-seeking behaviors of basic science researchers to inform the development of customized library services. A qualitative study using semi-structured interviews was conducted on a sample of basic science researchers employed at a university medical school. The basic science researchers used a variety of information resources ranging from popular Internet search engines to highly technical databases. They generally relied on basic keyword searching, using the simplest interface of a database or search engine. They were highly collegial, interacting primarily with coworkers in their laboratories and colleagues employed at other institutions. They made little use of traditional library services and instead performed many traditional library functions internally. Although the basic science researchers expressed a positive attitude toward the library, they did not view its resources or services as integral to their work. To maximize their use by researchers, library resources must be accessible via departmental websites. Use of library services may be increased by cultivating relationships with key departmental administrative personnel. Despite their self-sufficiency, subjects expressed a desire for centralized information about ongoing research on campus and shared resources, suggesting a role for the library in creating and managing an institutional repository.

    Co-occurrence of drinking and smoking is prevalent in undergraduate students. A drinker self-schema-cognition about the self as the drinker-is a common identity in undergraduates and a well-known predictor of drinking behaviors. Given that smoking commonly occurs in the context of drinking, a drinker self-schema may be a cognitive mechanism to motivate co-occurring alcohol and tobacco use (i.e., cross-substance facilitation hypothesis). This study was to determine whether the drinker self-schema influences the processing of drinking- and smoking-related information and facilitates the co-occurrence of alcohol and tobacco use in undergraduate students who drink and smoke but do not self-identify as smokers. This study was the second phase of a 2-phase study. Of the 330 who completed phase 1 (online survey), 99 completed the phase 2 study. Phase 2 was an in-person session that included a computerized information processing task to measure endorsements and response latencies for drinking- and smoking-related attributes, and a computerized Timeline Followback that was used to measure 90-day alcohol- and tobacco-use behaviors. The 5-item drinker self-schema scale, administered in phase 1, was used to measure the strength of the drinker self-schema. A higher drinker self-schema score was associated with more endorsements of positive attributes for drinking and smoking, fewer endorsements of negative attributes for smoking, faster processing of agreements with positive alcohol-use-related attributes, higher levels of drinking and smoking, and more days of co-occurring alcohol and tobacco use. Findings provide preliminary evidence to support the cross-substance facilitation hypothesis that the drinker self-schema facilitates the processing of not only drinking-related but also smoking-related stimuli and behaviors. Undergraduates who have higher drinker self-schema scores may be vulnerable to co-occurring alcohol and tobacco use.

    According to the temporal theory of autism spectrum disorders (ASDs), audiovisual changes in environment, particularly those linked to facial and verbal language, are often too fast to be faced, perceived, and/or interpreted online by many children with ASD, which could help explain their facial, verbal, and/or socioemotional interaction impairments. Our goal here was to test for the first time the impact of slowed-down audiovisual information on verbal cognition and behavior in 2 boys with ASD and verbal delay. Using 15 experimental sessions during 4 months, both boys were presented with various stimuli (eg, pictures, words, sentences, cartoons) and were then asked questions or given instructions regarding stimuli. The audiovisual stimuli and instructions/questions were presented on a computer's screen and were always displayed twice: at real-time speed (RTS) and at slowed-down speed (SDS) using the software Logiral. We scored the boys' verbal cognition performance (ie, ability to understand questions/instructions and answer them verbally/nonverbally) and their behavioral reactions (ie, attention, verbal/nonverbal communication, social reciprocity), and analyzed the effects of speed and order of the stimuli presentation on these factors. According to the results, both participants exhibited significant improvements in verbal cognition performance with SDS presentation compared with RTS presentation, and they scored better with RTS presentation when having SDS presentation before rather than after RTS presentation. Behavioral reactions were also improved in SDS conditions compared with RTS conditions. This initial evidence of a positive impact of slowed-down audiovisual information on verbal cognition should be tested in a large cohort of children with ASD and associated speech/language impairments.

    Comprehensive behavior change frameworks are needed to provide guidance for the design, implementation, and evaluation of diabetes self-care programs in diverse populations. We applied the Information-Motivation-Behavioral Skills (IMB) model, a well-validated, comprehensive health behavior change framework, to diabetes self-care. Patients with diabetes were recruited from an outpatient clinic. Information gathered pertained to demographics, diabetes knowledge (information); diabetes fatalism (personal motivation); social support (social motivation); and diabetes self-care (behavior). Hemoglobin A1C values were extracted from the patient medical record. Structural equation models tested the IMB framework. More diabetes knowledge (r=0.22 pbehavior; and through behavior, were related to glycemic control (r=-0.20, pmotivation (less fatalistic attitudes), and social motivation (more social support) was associated with behavior; and behavior was the sole predictor of glycemic control. The IMB model is an appropriate, comprehensive health behavior change framework for diabetes self-care. The findings indicate that in addition to knowledge, diabetes education programs should target personal and social motivation to effect behavior change. 2009 Elsevier Ireland Ltd.

    Digby, Cynthia Louise Barrett

    The purpose of this research is to consider the environmental knowledge, attitudes, and behaviors, of adults in Minnesota, and possible factors that influence environmental literacy. Specifically, this study is designed to: (1) measure the environmental literacy of Minnesota adults, (2) explore possible relationships between Minnesota adults, environmental literacy variables and their demographic, non-formal and informal learning, and (3) determine the relative contribution of demographic and learning variables for predicting environmental knowledge, attitudes and behaviors. This research was accomplished by conducting a secondary data analysis of The Third Minnesota Report Card on Environmental Literacy: A Survey of Adult Environmental Knowledge, Attitudes and Behavior (Murphy & Olson, 2008). Phone interviews were completed between August and November 2007 with one thousand adults throughout Minnesota. Findings indicated that for age, education, and income, there was a weak positive relationship with environmental knowledge, attitude and behavior scores. There was a significant effect for gender and environmental knowledge scores, with males receiving higher environmental knowledge scores than females. There was a significant effect for gender and environmental attitudes, and behavior scores as well, with females receiving slightly higher environmental attitude and behavior scores than males. After controlling for the effects of demographic variables on environmental knowledge, attitudes and behaviors, non-formal learning participation appears to be a moderate contributor to both environmental knowledge and environmental behaviors. After controlling for the effects of demographic variables on environmental knowledge, attitudes and behaviors, informal learning participation appears to be a slight contributor to environmental attitudes, and a moderate contributor to environmental knowledge and behaviors. Overall, the results of this study suggest that participation

    Background Information in oncological consultations is often excessive. Those patients who better recall information are more satisfied, less anxious and more adherent. Optimal recall may be enhanced by the oncologist's non-verbal communication. We tested the influence of three non-verbal behaviors, i.e. eye contact, body posture and smiling, on patients' recall of information and perceived friendliness of the oncologist. Moreover, the influence of patient characteristics on recall was examined, both directly or as a moderator of non-verbal communication. Material and methods Non-verbal communication of an oncologist was experimentally varied using video vignettes. In total 194 breast cancer patients/survivors and healthy women participated as 'analog patients', viewing a randomly selected video version while imagining themselves in the role of the patient. Directly after viewing, they evaluated the oncologist. From 24 to 48 hours later, participants' passive recall, i.e. recognition, and free recall of information provided by the oncologist were assessed. Results Participants' recognition was higher if the oncologist maintained more consistent eye contact (β = 0.17). More eye contact and smiling led to a perception of the oncologist as more friendly. Body posture and smiling did not significantly influence recall. Older age predicted significantly worse recognition (β = -0.28) and free recall (β = -0.34) of information. Conclusion Oncologists may be able to facilitate their patients' recall functioning through consistent eye contact. This seems particularly relevant for older patients, whose recall is significantly worse. These findings can be used in training, focused on how to maintain eye contact while managing computer tasks.

    Geoscience educators use a variety of resources and resource formats in their classroom teaching to facilitate student understanding of concepts and processes that define subject areas considered in the realm of geoscience. In this study of information needs and behaviors of geoscience educators, the researcher found that participants preferred visual media such as personal photographic and digital images, as well as published figures, animations, and cartoons, and that participants bypassed their academic libraries to meet these information needs. In order to investigate the role of information in developing introductory geoscience course and instruction, a grounded theory study was conducted through a qualitative paradigm with an interpretive approach and naturalistic inquiry. The theoretical and methodological framework was constructivism and sense-making. Research questions were posited on the nature of geoscience subject areas and the resources and resource formats used in conveying geoscience topics to science and non-science majors, as well as educators' preferences and concerns with curriculum and instruction. The underlying framework was to investigate the place of the academic library and librarian in the sense-making, constructivist approach of geoscience educators. A purposive sample of seven geoscience educators from four universities located in mid-western United States was identified as exemplary teachers by department chairpersons. A triangulation of data collection methods included semi-structured interviews, document reviews, and classroom observations. Data were analyzed using the constant comparative method, which included coding, categorizing, and interpreting for patterns and relationships. Contextual factors were identified and a simple model resulted showing the role of information in teaching for these participants. While participants developed lectures and demonstrations using intrapersonal knowledge and personal collections, one barrier

    Primary caregivers of very young children are subject to excessive and often disparate information regarding the instilling of healthful eating behaviors. Our study focuses on the integration of the operant resources of primary caregivers (i.e., their knowledge and modeling skills) and that of their very young children (i.e., their self-regulation of energy intake and food preferences) to co-create healthful eating behaviors as a measure to curb overweight and obesity in adulthood. Our two-stage qualitative study makes original contributions demonstrating that primary caregivers' efforts to co-create healthful eating behaviors with their very young children are adversely affected by information overload.

    To evaluate pharmacy staff perspectives of a 2-year pharmacy intervention aimed at reducing unintended pregnancy in 18- to 30-year-old women. Pharmacy staff completed a 48-item, self-administered paper survey consisting of scaled and open-ended questions. 55 community pharmacies in 12 Iowa counties. All pharmacy staff participated, including pharmacists, pharmacy technicians, and other pharmacy employees. Online continuing education (CE) training was made available to all pharmacy staff. Promotional materials including posters, brochures, and shelf talkers were displayed in all of the pharmacies. Pharmacy staff perceptions and self-reported behaviors related to displaying posters, brochures, and shelf talkers in their pharmacies and providing contraceptive information and counseling to patients/customers. A total of 192 (43% return rate) pharmacy staff responded. Only 44% of respondents consistently provided contraceptive information and counseling, yet more than 90% felt that talking with patients/customers about contraceptives was easy, and more than 50% could do so privately. The study showed increased pharmacy staff desire to make this topic a priority. Community pharmacy staff can play a key role in educating and counseling young adult women about contraceptive health and pregnancy planning. This study indicates that staff are comfortable providing this service and that patients/customers are open to receiving guidance from pharmacists. However, pharmacy staff are missing additional opportunities to provide information and counseling. There is also a need for greater attention to provision of nonprescription contraceptive education.

    Launching a prevention campaign to contain the spread of infection requires substantial financial investments; therefore, a trade-off exists between suppressing the epidemic and containing costs. Information exchange among individuals can occur as physical contacts (e.g., word of mouth, gatherings), which provide inherent possibilities of disease transmission, and non-physical contacts (e.g., email, social networks), through which information can be transmitted but the infection cannot be transmitted. Contact network (CN) incorporates physical contacts, and the information dissemination network (IDN) represents non-physical contacts, thereby generating a multilayer network structure. Inherent differences between these two layers cause alerting through CN to be more effective but more expensive than IDN. The constraint for an epidemic to die out derived from a nonlinear Perron-Frobenius problem that was transformed into a semi-definite matrix inequality and served as a constraint for a convex optimization problem. This method guarantees a dying-out epidemic by choosing the best nodes for adopting preventive behaviors with minimum monetary resources. Various numerical simulations with network models and a real-world social network validate our method.

    This paper aimed to determine the relationship between cancer information scanning and seeking experience of adolescents and cancer preventive behavior, perceived cancer risk, and levels of cancer- related knowledge. The study sample comprised 1,000 second-year students from 6 high schools: the general and vocational school systems were each represented by 1 boys', 1 girls', and 1 coeducational high school. In July 2011, trained researchers visited each classroom, explained the purpose of the study, distributed questionnaires to the students who agreed to participate, instructed them to complete the survey by self-reporting, and collected the completed questionnaires. The students who attended general high schools (as compared with vocational high schools), earned higher grades, consumed more vegetables, had a higher perceived cancer risk, and answered the cancer-related questions more correctly and had more cancer information scanning and seeking experience. These results reinforce the importance of cancer prevention health education. Furthermore, the results may help in preparing a strategy that enables people to acquire accurate cancer-related information easily and quickly.

    2018-03-02

    Diagnoses of personality disorders (PD) must rely on judgments of observers-either clinicians or acquaintances-because personality disorders are primarily defined in terms of maladaptive interpersonal behavior. Little is known, however, about how closely acquaintances' judgments of PD traits relate to self-reports of theoretically relevant Big Five traits or directly observed behavioral outcomes in interpersonal situations. The present study examines associations between judgments of the 10 PD traits provided by close acquaintances, self-reports of PD-relevant Big Five personality traits, and observed interpersonal behaviors across three different three-person laboratory interactions (i.e., unstructured chat, cooperative task, competitive game). The sample consisted of 256 undergraduate students (130 females; M age  = 19.83, SD = 1.25). Four unacquainted observers independently rated participants' behaviors from video recordings. In line with previous work, informant reports of PD traits demonstrate strong convergent validity with relevant self-reported Big Five traits (as identified by Lynam & Widiger, 2001). Directly observed behavior is meaningfully associated with acquaintances' judgments and self-reports of PD-relevant traits, and the associations between these judgments and behavior are strongest for traits associated with histrionic and schizoid PD. Vector correlations between behavioral profiles associated with informant and self-reports show that both assessments have similar behavioral correlates. Associations between PD trait ratings and behavior appeared to differ as a function of gender, with males showing more and stronger correlations. Informants' ratings of PD traits are impressively accurate, converging both with self-reports of relevant traits and directly observed interpersonal behavior. Therefore, a comprehensive understanding of PDs and associated traits can be augmented by information from multiple acquaintances who have the

    Analyzing the contents of online social networks is an effective process for monitoring and understanding peoples' behaviors. Since the nature of conversation and information propagation is similar to traditional conversation and learning, one of the popular socio-cognitive methods, social cognitive theory was applied to online social networks to. Two major news topics about colon cancer were chosen to monitor traffic of Twitter messages. The activity of "leaders" on the issue (i.e., news companies or people will prior Twitter activity on topics related to colon cancer) was monitored. In addition, the activity of "followers", people who never discussed the topics before, but replied to the discussions was also monitored. Topics that produce tangible benefits such as positive outcomes from appropriate preventive actions received dramatically more attention and online social media traffic. Such characteristics can be explained with social cognitive theory and thus present opportunities for effective health campaigns.

    Visually impaired people may legally drive if wearing bioptic telescopes in some developed countries. To address the controversial safety issue of the practice, we have developed a low-cost in-car recording system that can be installed in study participants' own vehicles to record their daily driving activities. We also developed a set of automated identification techniques of informative behaviors to facilitate efficient manual review of important segments submerged in the vast amount of uncontrolled data. Here, we present the methods and quantitative results of the detection performance for six types of driving maneuvers and behaviors that are important for bioptic driving: bioptic telescope use, turns, curves, intersections, weaving, and rapid stops. The testing data were collected from one normally sighted and two visually impaired subjects across multiple days. The detection rates ranged from 82% up to 100%, and the false discovery rates ranged from 0% to 13%. In addition, two human observers were able to interpret about 80% of targets viewed through the telescope. These results indicate that with appropriate data processing the low-cost system is able to provide reliable data for natural bioptic driving studies.

    Socially disruptive behavior during peer interactions in early childhood is detrimental to children's social, emotional, and academic development. Few studies have investigated the developmental underpinnings of children's socially disruptive behavior using genetically sensitive research designs that allow examination of parent-on-child and child-on-parent (evocative genotype-environment correlation [rGE]) effects when examining family process and child outcome associations. Using an adoption-at-birth design, the present study controlled for passive genotype-environment correlation and directly examined evocative rGE while examining the associations between family processes and children's peer behavior. Specifically, the present study examined the evocative effect of genetic influences underlying toddler low social motivation on mother-child and father-child hostility and the subsequent influence of parent hostility on disruptive peer behavior during the preschool period. Participants were 316 linked triads of birth mothers, adoptive parents, and adopted children. Path analysis showed that birth mother low behavioral motivation predicted toddler low social motivation, which predicted both adoptive mother-child and father-child hostility, suggesting the presence of an evocative genotype-environment association. In addition, both mother-child and father-child hostility predicted children's later disruptive peer behavior. Results highlight the importance of considering genetically influenced child attributes on parental hostility that in turn links to later child social behavior. Implications for intervention programs focusing on early family processes and the precursors of disrupted child social development are discussed.

    Information in critical care environments is distributed across multiple sources, such as paper charts, electronic records, and support personnel. For decision-making tasks, physicians have to seek, gather, filter and organize information from various sources in a timely manner. The objective of this research is to characterize the nature of physicians' information seeking process, and the content and structure of clinical information retrieved during this process. Eight medical intensive care unit physicians provided a verbal think-aloud as they performed a clinical diagnosis task. Verbal descriptions of physicians' activities, sources of information they used, time spent on each information source, and interactions with other clinicians were captured for analysis. The data were analyzed using qualitative and quantitative approaches. We found that the information seeking process was exploratory and iterative and driven by the contextual organization of information. While there was no significant differences between the overall time spent paper or electronic records, there was marginally greater relative information gain (i.e., more unique information retrieved per unit time) from electronic records (t(6)=1.89, p=0.1). Additionally, information retrieved from electronic records was at a higher level (i.e., observations and findings) in the knowledge structure than paper records, reflecting differences in the nature of knowledge utilization across resources. A process of local optimization drove the information seeking process: physicians utilized information that maximized their information gain even though it required significantly more cognitive effort. Implications for the design of health information technology solutions that seamlessly integrate information seeking activities within the workflow, such as enriching the clinical information space and supporting efficient clinical reasoning and decision-making, are discussed.

    The study's aim was to test prospective associations between information, motivation, and behavioral skills (IMB model) and self-care behaviors (diet, exercise, and blood glucose testing) among patients with type 2 diabetes. 295 participants were surveyed one (T1), six (T2), and 12 (T3) months after a diabetes course. Cross-lagged panel analyses were performed to test unidirectional and bidirectional relationships between IMB model variables and self-care behaviors. Blood-glucose testing at T1 was positively related to information at T2, which in turn was positively related to blood-glucose testing at T3. Controlled motivation at T1 was positively related to exercise at T2. Autonomous motivation at T2 was positively associated with exercise at T3. There was a positive bidirectional relationship across time between behavioral skills and general diet. Patterns of prospective associations between IMB model variables and diabetes self-care depend on the self-care behavior considered. This model offers an interesting framework for examining how diabetes self-care behaviors evolve. Diabetes education programs should provide information about current health status and promote experiential learning to help patients realize the impact of their behaviors on glycemic control; should foster autonomous motivation for long-term change; and should build on patients' strengths and skills.

    Declining participation in recreational angling is of great concern to fishery managers because fishing license sales are an important revenue source for protection of aquatic resources. This decline is frequently attributed, in part, to increased societal reliance on electronics. Internet use by anglers is increasing and fishery managers may use the Internet as a unique means to increase angler participation. We examined Internet search behavior using Google Insights for Search, a free online tool that summarizes Google searches from 2004 to 2011 to determine (1) trends in Internet search volume for general fishing related terms and (2) the relative usefulness of terms related to angler recruitment programs across the United States. Though search volume declined for general fishing terms (e.g., fishing, fishing guide), search volume increased for social media and recruitment terms (e.g., fishing forum, family fishing) over the 7-year period. We encourage coordinators of recruitment programs to capitalize on anglers’ Internet usage by considering Internet search patterns when creating web-based information. Careful selection of terms used in web-based information to match those currently searched by potential anglers may help to direct traffic to state agency websites that support recruitment efforts.

    To behave in a robust and adaptive way, animals must extract task-relevant sensory information efficiently. One way to understand how they achieve this is to explore regularities within the information animals perceive during natural behavior. In this chapter, we describe how we have used artificial neural networks (ANNs) to explore efficiencies in vision and memory that might underpin visually guided route navigation in complex worlds. Specifically, we use three types of neural network to learn the regularities within a series of views encountered during a single route traversal (the training route), in such a way that the networks output the familiarity of novel views presented to them. The problem of navigation is then reframed in terms of a search for familiar views, that is, views similar to those associated with the route. This approach has two major benefits. First, the ANN provides a compact holistic representation of the data and is thus an efficient way to encode a large set of views. Second, as we do not store the training views, we are not limited in the number of training views we use and the agent does not need to decide which views to learn.

    Full Text Available In recent years, borders between countries have been opened gradually thanks to globalization, which is reflected in minimal barriers to the movement of persons and capital. This situation could be potentially abused by taxpayers willing to shift the capital to preferential tax jurisdictions. Due to facts aforementioned, several instruments for tax administrators have been introduced. Bilateral and multilateral instruments are concluded with particular countries for the purpose of obtaining information about foreign residents staying abroad but also to avoid double taxation or double non‑taxation. In recent years there has been an increased number of companies in the Czech Republic whose owners come from preferential tax jurisdiction from 12,676 up to 13,167. This paper is focused on the Czech taxpayers’ reaction on concluding agreements concerning exchange of information in tax matters with preferential tax jurisdictions, the so‑called “Tax havens”. The Difference‑in‑Differences Method was carried out to predict the taxpayers’ behavior. The model shows that the agreements work well as a preventive tool. If the Czech Republic concludes the agreement with the tax haven, the taxpayers lose their anonymity. This results in their relocation into tax havens that are not covered by the agreement in order to keep their anonymity.

    Full Text Available Wound care in the hospital environment continues at home after discharge and performed by the informal caregiver. The objective of this study was to characterize the behavior of the informal caregiver during the treatment of wounds in hospitalized patient. This is a prospective study with 39 caregivers of wounded patients in a university hospital in the Brazilian Midwest. We collected the data through direct non-participant observation and interview. We found that 94.9% of the caregivers remained in the ward during the dressing. Of these, 97.3% were close to the patient; 73% observed closely; 54.1% were familiar to the evolution of the wound; 59.5% were involved in the procedure and questioned about the dressing and/or used materials. Most caregivers of persons hospitalized with wounds are interested in and somehow participate of the dressing procedure. The nursing staff can take advantage of such moments to guide the caregivers and prepare them for homecare.

    Primary care behavioral health (PCBH) is a population-based approach to delivering mental and behavioral health care in the primary care setting. Implementation of the PCBH model varies across practice settings, which can impact how PCBH providers deliver services to patients and in turn may predict a variety of important outcomes. This article aims to characterize PCBH provider engagement in key processes of integrated care as demonstrated in results from empirical studies of real-world clinical practice. For this narrative review of published studies on PCBH provider engagement in processes of care, PubMed and PsycINFO databases were searched from January 1990 through May 2016 to identify relevant articles. Provider adherence to the brief, time-limited treatment model appears suboptimal. Common mental health conditions, such as depression, were often the primary focus of provider attention, with less consistent emphasis on behavioral medicine concerns. Whereas providers regularly conducted qualitative functional assessments with patients, routine use of standardized measures was low. Engagement in interprofessional collaboration with the primary care team was also low, but engagement in behaviors that fostered therapeutic relationships was high. This review identified several strengths and weaknesses of typical PCBH provider practices. Results are discussed in relation to their value as areas for future quality improvement initiatives that can improve PCBH service delivery and, ultimately, patient outcomes.

    The purpose of patient information leaflets (PILs) is to inform patients about the administration, precautions and potential side effects of their prescribed medication. Despite European Commission guidelines aiming at increasing readability and comprehension of PILs little is known about the potential risk information has on patients. This article explores patients' reactions and subsequent behavior towards risk information conveyed in PILs of commonly prescribed drugs by general practitioners (GPs) for the treatment of Type 2 diabetes, hypertension or hypercholesterolemia; the most frequent cause for consultations in family practices in Germany. We conducted six focus groups comprising 35 patients which were recruited in GP practices. Transcripts were read and coded for themes; categories were created by abstracting data and further refined into a coding framework. Three interrelated categories are presented: (i) The vast amount of side effects and drug interactions commonly described in PILs provoke various emotional reactions in patients which (ii) lead to specific patient behavior of which (iii) consulting the GP for assistance is among the most common. Findings show that current description of potential risk information caused feelings of fear and anxiety in the reader resulting in undesirable behavioral reactions. Future PILs need to convey potential risk information in a language that is less frightening while retaining the information content required to make informed decisions about the prescribed medication. Thus, during the production process greater emphasis needs to be placed on testing the degree of emotional arousal provoked in patients when reading risk information to allow them to undertake a benefit-risk-assessment of their medication that is based on rational rather than emotional (fearful) reactions.

Exercise, smoking cessation, medication adherence, and other healthy behavior can help prevent, or even treat, some diseases. Consequently, interventions that promote healthy behavior have become increasingly common in health care settings. Many of these interventions award incentives contingent upon preventive health-related behavior. Incentive-based interventions vary considerably along several dimensions, including who is targeted in the intervention, which behavior is targeted, and what type of incentive is used. More research on the quantitative and qualitative features of many of these variables is still needed to inform treatment. However, extensive literature on basic and applied behavior analytic research is currently available to help guide the study and practice of incentive-based treatment in health care. In this integrated review, we discuss how behavior analytic research and theory can help treatment providers design and implement incentive-based interventions that promote healthy behavior.

    Social media, mobile and wearable technology, and connected devices have significantly expanded the opportunities for conducting biomedical research online. Electronic consent to collecting such data, however, poses new challenges when contrasted to traditional consent processes. It reduces the participant-researcher dialogue but provides an opportunity for the consent deliberation process to move from solitary to social settings. In this research, we propose that social annotations, embedded in the consent form, can help prospective participants deliberate on the research and the organization behind it in ways that traditional consent forms cannot. Furthermore, we examine the role of the comments' valence on prospective participants' beliefs and behavior. This study focuses specifically on the influence of annotations' valence on participants' perceptions and behaviors surrounding online consent for biomedical research. We hope to shed light on how social annotation can be incorporated into digitally mediated consent forms responsibly and effectively. In this controlled between-subjects experiment, participants were presented with an online consent form for a personal genomics study that contained social annotations embedded in its margins. Individuals were randomly assigned to view the consent form with positive-, negative-, or mixed-valence comments beside the text of the consent form. We compared participants' perceptions of being informed and having understood the material, their trust in the organization seeking the consent, and their actual consent across conditions. We find that comment valence has a marginally significant main effect on participants' perception of being informed (F2=2.40, P=.07); specifically, participants in the positive condition (mean 4.17, SD 0.94) felt less informed than those in the mixed condition (mean 4.50, SD 0.69, P=.09). Comment valence also had a marginal main effect on the extent to which participants reported trusting the

    High levels of adherence to antiretroviral therapy (ART) are critical to the management of HIV, yet many people living with HIV do not achieve these levels. There is a substantial body of literature regarding correlates of adherence to ART, and theory-based multivariate models of ART adherence are emerging. The current study assessed the determinants of adherence behavior postulated by the Information-Motivation-Behavioral Skills model of ART adherence in a sample of 149 HIV-positive patients in Mississippi. Structural equation modeling indicated that ART-related information correlated with personal and social motivation, and the two sub-areas of motivation were not intercorrelated. In this Deep South sample, being better informed, socially supported, and perceiving fewer negative consequences of adherence were independently related to stronger behavioral skills for taking medications, which in turn associated with self-reported adherence. The IMB model of ART adherence appeared to well characterize the complexities of adherence for this sample.

    Background The Internet’s potential impact on suicide is of major public health interest as easy online access to pro-suicide information or specific suicide methods may increase suicide risk among vulnerable Internet users. Little is known, however, about users’ actual searching and browsing behaviors of online suicide-related information. Objective To investigate what webpages people actually clicked on after searching with suicide-related queries on a search engine and to examine what queries people used to get access to pro-suicide websites. Methods A retrospective observational study was done. We used a web search dataset released by America Online (AOL). The dataset was randomly sampled from all AOL subscribers’ web queries between March and May 2006 and generated by 657,000 service subscribers. Results We found 5526 search queries (0.026%, 5526/21,000,000) that included the keyword "suicide". The 5526 search queries included 1586 different search terms and were generated by 1625 unique subscribers (0.25%, 1625/657,000). Of these queries, 61.38% (3392/5526) were followed by users clicking on a search result. Of these 3392 queries, 1344 (39.62%) webpages were clicked on by 930 unique users but only 1314 of those webpages were accessible during the study period. Each clicked-through webpage was classified into 11 categories. The categories of the most visited webpages were: entertainment (30.13%; 396/1314), scientific information (18.31%; 240/1314), and community resources (14.53%; 191/1314). Among the 1314 accessed webpages, we could identify only two pro-suicide websites. We found that the search terms used to access these sites included “commiting suicide with a gas oven”, “hairless goat”, “pictures of murder by strangulation”, and “photo of a severe burn”. A limitation of our study is that the database may be dated and confined to mainly English webpages. Conclusions Searching or browsing suicide-related or pro-suicide webpages was

    Suboptimal adherence to diabetes medications is prevalent and associated with unfavorable health outcomes, but it remains unclear what intervention content is necessary to effectively promote medication adherence in diabetes. In other disease contexts, the Information-Motivation-Behavioral skills (IMB) model has effectively explained and promoted medication adherence and thus may have utility in explaining and promoting adherence to diabetes medications. We tested the IMB model's hypotheses in a sample of adults with type 2 diabetes. Participants (N = 314) completed an interviewer-administered survey and A1C test. Structural equation models tested the effects of diabetes medication adherence-related information, motivation, and behavioral skills on medication adherence and the effect of medication adherence on A1C. The IMB elements explained 41% of the variance in adherence, and adherence explained 9% of the variance in A1C. As predicted, behavioral skills had a direct effect on adherence (β = 0.59; P information (indirect effect 0.08 [0.01-0.15]) and motivation (indirect effect 0.12 [0.05-0.20]) on adherence. Medication adherence significantly predicted glycemic control (β = -0.30; P information, motivation, and behavioral skills and assessing the degree to which change in these determinants leads to changes in medication adherence behavior.

    Past research has shown abundant comorbidity between physical chronic health conditions and mental illness. The focal point of the conversation to reduce cost is better care coordination through the implementation of health information technology (HIT). At the policy level, the Health Information Technology for Economic and Clinical Health Act of 2009 (HITECH Act) was implemented as a way to increase the implementation of HIT. However, behavioral health providers have been largely excluded from obtaining access to the funds provided by the HITECH Act. Without further intervention, disjointed care coordination between physical and behavioral health providers will continue.

    The purpose of this study was to examine the breast cancer prevention information seeking behaviors among rural women, the prevalence of Internet, cell, and text use, and interest to receive breast cancer prevention information cell and text messages. While growing literature for breast cancer information sources supports the use of the Internet, little is known about breast cancer prevention information seeking behaviors among rural women and mobile technology. Using a cross-sectional study design, data were collected using a survey. McGuire's Input-Ouput Model was used as the framework. Self-reported data were obtained from a convenience sample of 157 women with a mean age of 60 (SD = 12.12) at a rural New Mexico imaging center. Common interpersonal information sources were doctors, nurses, and friends and common channel information sources were television, magazines, and Internet. Overall, 87% used cell phones, 20% had an interest to receive cell phone breast cancer prevention messages, 47% used text messaging, 36% had an interest to receive text breast cancer prevention messages, and 37% had an interest to receive mammogram reminder text messages. Bivariate analysis revealed significant differences between age, income, and race/ethnicity and use of cell phones or text messaging. There were no differences between age and receiving text messages or text mammogram reminders. Assessment of health information seeking behaviors is important for community health educators to target populations for program development. Future research may identify additional socio-cultural differences.

A personal information questionnaire developed by the authors was used to collect sociodemographic data, including sexual behavior, sexual attitude, and sources of information about sex. The findings show that there was a significant increase in intercourse and flirting behavior from 1996 to 2004, although no significant difference in masturbation was observed. Additionally, the number of male adolescents that reported family and pornographic films as their sources of information about sex increased 1.6-fold and 2.9-fold, respectively. A significant relationship between watching pornographic films and engaging in sexual intercourse was noted. The number of male adolescents age mean 16, engaging in sexual intercourse increased between 1996 and 2004. Pornographic films were observed to be the most common source of information about sex and also predicted the probability of adolescents having sex. Findings that indicate the need for better and more accurate sources of information about sex. The availability of good quality information about sex is critical to the development of the sexual identity and mental health of male adolescents.

    To determine the health literacy levels of persons living with human immunodeficiency virus (HIV) (PLWH) at a health clinic in the Dominican Republic (DR) and assess associations between health literacy, HIV-related knowledge, and health information behavior (how patients need, seek, receive, and use information). Cross-sectional, descriptive. Participants were 107 PLWH attending the Clinic. A theoretically based, 64-item survey assessing information behavior and HIV-related knowledge was administered in Spanish through individual interviews. Health literacy was assessed using the Short Assessment of Health Literacy-Spanish and English. On average, participants were 40.8 years old and had lived with HIV for 7.7 years. The majority (69.2%) had low health literacy. HIV-related knowledge and information behavior varied by health literacy level and uncertainty regarding a main indicator of disease progression, viral load, was demonstrated regardless of health literacy level. Participants with low health literacy were less likely to answer questions or answer questions correctly and many participants (39.2%) indicated viral transmission can occur through supernatural means. Findings demonstrate unmet information need and that information received may not always be understood. Methods to improve health education are needed to ensure patients receive health information in an understandable way. © 2017 Wiley Periodicals, Inc.

    The nuclear and radioactive facilities can emit to the environment effluents that contain radionuclides, which are dispersed and/or its accumulate in the atmosphere, the terrestrial surface and the surface waters. As part of the evaluations of radiological impact, it requires to be carried out qualitative and quantitative analysis. In many of the cases it doesn't have the real values of the parameters that are used in the modelling, neither it is possible to carry out their measure, for that to be able to carry out the evaluation it needs to be carried out an extensive search of that published in the literature about the possible values of each parameter, under similar conditions to the object of study, this work can be extensive. In this work the characteristics of the VALORA Database System developed with the purpose of organizing and to automate significant information that it appears in different sources (scientific or technique literature) of the parameters that are used in the modelling of the behavior of the pollutants in the environment and the values assigned to these parameters that are used in the evaluation of the radiological impact potential is described; VALORA allows the consultation and selection of the characteristic parametric data of different situations and processes that are required by the calculation pattern implemented. The software VALORA it is a component of a group of tools computer that have as objective to help to the resolution of dispersion models and transfer of pollutants. (Author)

    In the work the process of formation of trainee characteristics with their subsequent change is analyzed and analyzed. Characteristics of trainees were obtained as a result of testing for each section of information on the chosen discipline. The results obtained during testing were input to the dynamic system. The area of control actions consisting of elements of the dynamic system is formed. The limit of deterministic predictability of element trajectories in dynamical systems based on local or global attractors is revealed. The dimension of the phase space of the dynamic system is determined, which allows estimating the parameters of the initial system. On the basis of time series of observations, it is possible to determine the predictability interval of all parameters, which make it possible to determine the behavior of the system discretely in time. Then the measure of predictability will be the sum of Lyapunov’s positive indicators, which are a quantitative measure for all elements of the system. The components for the formation of an algorithm allowing to determine the correlation dimension of the attractor for known initial experimental values of the variables are revealed. The generated algorithm makes it possible to carry out an experimental study of the dynamics of changes in the trainee’s parameters with initial uncertainty.

    The present study explored eye scan behavior as a function of level of subject training. Oculometric (eye scan) measures were recorded from each of ten subjects during training trials on a CRT based flight simulation task. The task developed for the study incorporated subtasks representative of specific activities performed by pilots, but which could be performed at asymptotic levels within relatively short periods of training. Changes in eye scan behavior were examined as initially untrained subjects developed skill in the task. Eye scan predictors of performance on the task were found. Examination of eye scan in proximity to selected task events revealed differences in the distribution of looks at the instruments as a function of level of training.

    Uncertainty management theory (UMT; Brashers, 2001, 2007) is rooted in the assumption that, as opposed to being inherently negative, health-related uncertainty is appraised for its meaning. Appraisals influence subsequent behaviors intended to manage uncertainty, such as information seeking. This study explores the connections among uncertainty, appraisal, and information-seeking behavior proposed in UMT. A laboratory study was conducted in which participants (N = 157) were primed to feel and desire more or less uncertainty about skin cancer and were given the opportunity to search for skin cancer information using the World Wide Web. The results show that desired uncertainty level predicted appraisal intensity, and appraisal intensity predicted information-seeking depth-although the latter relationship was in the opposite direction of what was expected.

    Self-care is a crucial component of diabetes management. But comprehensive behavior change frameworks are needed to provide guidance for the design, implementation, and evaluation of diabetes self-care programs in diverse populations. We tested the Information-Motivation-Behavioral Skills (IMB) model in a sample of Chinese adults with Type 2 diabetes. A cross-sectional study of 222 Chinese adults with type 2 diabetes was conducted in a primary care center. We collected information on demographics, provider-patient communication (knowledge), social support (motivation), self-efficacy (behavioral skills), and diabetes self-care (behavior). The values of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) were also obtained. Measured variable path analyses were used to the IMB framework. Provider-patient communication (β = 0.12, p = .037), and social support (β = 0.19, p = .007) and self-efficacy (β = 0.41, p motivation and behavioral skills to effect behavior change.

    Background The Information-Motivation-Behavioral Skills (IMB) model often guides sexual risk reduction programs even though no studies have examined covariation in the theory’s constructs in a dynamic fashion with longitudinal data. Purpose Using new developments in latent growth modeling, we explore how changes in information, motivation, and behavioral skills over 9 months relate to changes in condom use among STD clinic patients. Methods Participants (N = 1281, 50% female, 66% African American) completed measures of IMB constructs at three time points. We used parallel process latent growth modeling to examine associations among intercepts and slopes of IMB constructs. Results Initial levels of motivation, behavioral skills, and condom use were all positively associated, with behavioral skills partially mediating associations between motivation and condom use. Changes over time in behavioral skills positively related to changes in condom use. Conclusions Results support the key role of behavioral skills in sexual risk reduction, suggesting these skills should be targeted in HIV prevention interventions. PMID:21638196

    E-health information has become an important resource for people seeking health information. Even though many studies have been conducted to examine the quality of e-health information, only a few studies have explored the effects of the information seekers' motivations on the perceived quality of e-health information. There is even less information about repeated searches for e-health information after the users' initial experience of e-health information use. Using an online survey of information seekers, 252 e-health information users' responses were collected. The research examines the relationship among motivation, perceived quality, satisfaction, and intention to repeat-search e-health information. The results identify motivations to search e-health information and confirm the relationship among motivation, perceived quality dimensions, and satisfaction and intention to repeat searches for e-health information.

    Clinical decision-making involves the interplay between cognitive processes and physicians' perceptions of confidence in the context of their information-seeking behavior. The objectives of the study are: to examine how these concepts interact, to determine whether physician confidence, defined in relation to information need, affects clinical decision-making, and if information access improves decision accuracy. We analyzed previously collected data about resident physicians' perceptions of information need from a study comparing abstracts and full-text articles in clinical decision accuracy. We found that there is a significant relation between confidence and accuracy (φ=0.164, p<0.01). We also found various differences in the alignment of confidence and accuracy, demonstrating the concepts of underconfidence and overconfidence across years of clinical experience. Access to online literature also has a significant effect on accuracy (p<0.001). These results highlight possible CDSS strategies to reduce medical errors.

    Externalizing psychopathology (EXT) is associated with low executive working memory (EWM) capacity and problems with inhibitory control and decision-making; however, the specific cognitive processes underlying these problems are not well known. This study used a linear ballistic accumulator computational model of go/no-go associative-incentive learning conducted with and without a working memory (WM) load to investigate these cognitive processes in 510 young adults varying in EXT (lifetime problems with substance use, conduct disorder, ADHD, adult antisocial behavior). High scores on an EXT factor were associated with low EWM capacity and higher scores on a latent variable reflecting the cognitive processes underlying disinhibited decision-making (more false alarms, faster evidence accumulation rates for false alarms [vFA], and lower scores on a Response Precision Index [RPI] measure of information processing efficiency). The WM load increased disinhibited decision-making, decisional uncertainty, and response caution for all subjects. Higher EWM capacity was associated with lower scores on the latent disinhibited decision-making variable (lower false alarms, lower vFAs and RPI scores) in both WM load conditions. EWM capacity partially mediated the association between EXT and disinhibited decision-making under no-WM load, and completely mediated this association under WM load. The results underline the role that EWM has in associative-incentive go/no-go learning and indicate that common to numerous types of EXT are impairments in the cognitive processes associated with the evidence accumulation-evaluation-decision process.

    The course of the Diels-Alder reactions of cyclopentadiene and maleic anhydride were studied. Two reaction paths were modelled: endo- and exo-selective paths. All structures within the transient region were characterized and analyzed by means of geometrical descriptors, physicochemical parameters and information-theoretical measures in order to observe the linkage between chemical behavior and the carriage of information. We have shown that the information-theoretical characterization of the chemical course of the reaction is in complete agreement with its phenomenological behavior in passing from reactants to products. In addition, we were able to detect the main differences between the two reaction mechanisms. This type of informational analysis serves to provide tools to help understand the chemical reactivity of the two simplest Diels-Alder reactions, which permits the establishment of a connection between the quantum changes that molecular systems exert along reaction coordinates and standard physicochemical phenomenology. In the present study, we have shown that every reaction stage has a family of subsequent structures that are characterized not solely by their phenomenological behavior but also by informational properties of their electronic density distribution (localizability, order, uniformity). Moreover, we were able to describe the main differences between endo-adduct and exo-adduct pathways. With the advent of new experimental techniques, it is in principle possible to observe the structural changes in the transient regions of chemical reactions. Indeed, through this work we have provided the theoretical concepts needed to unveil the concurrent processes associated with chemical reactions.

    To examine social information processing (SIP) skills, behavior problems, and social competence following adolescent TBI and to determine whether SIP skills were predictive of behavior problems and social competence. Cross-sectional analyses of adolescents with TBI recruited and enrolled in a behavioral treatment study currently in progress. Two tertiary care children's hospitals with Level 1 trauma centers. Adolescents aged 11 to 18 years with severe TBI (n=19) and moderate TBI (n=24) who were injured up to 24 months prior to recruitment. TBI severity, race, maternal education, and age at testing. a measure of SIP skills, Child Behavior Checklist (CBCL), Youth Self Report (YSR), and Home and Community Social Behavior Scale (HCSBS). The severe TBI group did not obtain significantly lower scores on the SIP measures than the moderate TBI group. In comparison to adolescents with moderate TBI, those with severe TBI had significantly more parent-reported externalizing behaviors and self-reported weaknesses in social competence. SIP skills were strong predictors of problems and social competence in adolescents with TBI. More specifically, an aggressive SIP style predicted externalizing problems and a passive SIP style predicted internalizing problems. Both passive and aggressive SIP skills were related to social competence and social problems. Adolescents with TBI are at risk for deficits in social and behavioral outcomes. SIP skills are strongly related to behavior problems and social competence in adolescents with TBI. SIP skills, social competence, and behavior problems are important targets for intervention that may be amenable to change and lead to improved functional outcomes following TBI.

    Incomplete information in food consumption is a relevant topic in agricultural economics. This paper proposes a theoretical model describing consumer behavior, market equilibrium and public intervention in an industry where consumers must rely on the information of interested parties such as producers or associations. We provide simple game theory model showing the link between price competition and the strategic use of information. If information are unverifiable (as in the case of credence attributes) firms may have no incentive to advertise true claims and consumer decisions may be biased. Our model incorporates the opportunistic behavior of self-interested information providers. The result is a model of competition in prices and information finding a potential for market failure and public intervention. In the paper we discuss the efficiency of three possible regulations: banning false claims, subsidizing advertising campaigns, and public statement if favor of true claims. In that context, some recent patents related to both the regulatory compliance in communication and to the reduction of asymmetric information between producers and consumers have been considered. Finally, we found that the efficiency of these policy tools is affected by the reputation of trustworthiness of the firms.

    Experimental Functional analysis (EFA) is considered the "gold standard" of behavioural assessment and its use is predictive of treatment success. However, EFA has a number of limitations including its lengthy nature, the high level of expertise required, and the reinforcement of challenging behaviour. This study aimed to further validate a novel interview-informed synthesised contingency analysis (IISCA). An open-ended interview and brief direct observation informed an IISCA for a young boy with autism who engaged in challenging behaviour. Resulting data supported the hypothesis that the target behaviour was multiply controlled by escape from demands and access to tangible items. An intervention comprised of most-to-least prompting, escape extinction, differential reinforcement and a high-probability instruction sequence was evaluated using a reversal design. This intervention reduced challenging behaviour to low levels and resulted in increased compliance. Findings support the status of the IISCA as a valid, practical, and effective process for designing function-based interventions.

    Laypeople increasingly use the Internet as a source of health information, but finding and discovering the right information remains problematic. These issues are partially due to the mismatch between the design of consumer health websites and the needs of health information seekers, particularly the lack of support for "exploring" health information. The aim of this research was to create a design for consumer health websites by supporting different health information-seeking behaviors. We created a website called Better Health Explorer with the new design. Through the evaluation of this new design, we derive design implications for future implementations. Better Health Explorer was designed using a user-centered approach. The design was implemented and assessed through a laboratory-based observational study. Participants tried to use Better Health Explorer and another live health website. Both websites contained the same content. A mixed-method approach was adopted to analyze multiple types of data collected in the experiment, including screen recordings, activity logs, Web browsing histories, and audiotaped interviews. Overall, 31 participants took part in the observational study. Our new design showed a positive result for improving the experience of health information seeking, by providing a wide range of information and an engaging environment. The results showed better knowledge acquisition, a higher number of page reads, and more query reformulations in both focused and exploratory search tasks. In addition, participants spent more time to discover health information with our design in exploratory search tasks, indicating higher engagement with the website. Finally, we identify 4 design considerations for designing consumer health websites and health information-seeking apps: (1) providing a dynamic information scope; (2) supporting serendipity; (3) considering trust implications; and (4) enhancing interactivity. Better Health Explorer provides strong

    Full Text Available This research applies a positive stereotype perspective to test the effect of individuals’ choices between pro-environmental versus pro-safety behavior, while considering the role of media exposure. We test our hypotheses in China, where both food-safety and environment are major issues and are widely covered by the media and government reports. Based on a quasi-experiments and survey questionnaires focused on attitudes towards disposable chopsticks, we find that individuals form cognitive perceptions in ways that either have stronger positive environmental or safety stereotypes. Based on these stereotypes, they either believe that reusable chopsticks are more environmentally friendly or that disposable chopsticks are safer, each impacting individuals’ choices differently. In addition, awareness of information related to the environment augments the link between environmental stereotypes and pro-environmental behavior, while having no influence on the effect of safety stereotypes on pro-safety behavior. On the other hand, while awareness of safety-related information accentuates the link between safety-related stereotypes and pro-safety behavior, it has no impact on the effect of environmental stereotypes on pro-environmental behavior.

    The research examined complementary and alternative medicine (CAM) information-seeking behaviors and preferences from short- to long-term cancer survival, including goals, motivations, and information sources. A mixed-methods approach was used with cancer survivors from the "Assessment of Patients' Experience with Cancer Care" 2004 cohort. Data collection included a mail survey and phone interviews using the critical incident technique (CIT). Seventy survivors from the 2004 study responded to the survey, and eight participated in the CIT interviews. Quantitative results showed that CAM usage did not change significantly between 2004 and 2015. The following themes emerged from the CIT: families' and friends' provision of the initial introduction to a CAM, use of CAM to manage the emotional and psychological impact of cancer, utilization of trained CAM practitioners, and online resources as a prominent source for CAM information. The majority of participants expressed an interest in an online information-sharing portal for CAM. Patients continue to use CAM well into long-term cancer survivorship. Finding trustworthy sources for information on CAM presents many challenges such as reliability of source, conflicting information on efficacy, and unknown interactions with conventional medications. Study participants expressed interest in an online portal to meet these needs through patient testimonials and linkage of claims to the scientific literature. Such a portal could also aid medical librarians and clinicians in locating and evaluating CAM information on behalf of patients.

    Wilson, Christopher David

    Despite the emphasis in modern zoos and aquaria on conservation and environmental education, we know very little about what people learn in these settings, and even less about how they learn it. Research on informal learning in settings such as zoos has suffered from a lack of theory, with few connections being made to theories of learning in formal settings, or to theories regarding the nature of the educational goals. This dissertation consists of three parts: the development and analysis of a test instrument designed to measure constructs of environmental learning in zoos; the application of the test instrument along with qualitative data collection in an evaluation designed to measure the effectiveness of a zoo's education programs; and the analysis of individually matched pre- and post-test data to examine how environmental learning takes place, with respect to the constructivist view of learning, as well as theories of environmental learning and the barriers to pro-environmental behavior. The test instrument consisted of 40 items split into four scales: environmental knowledge, attitudes toward the environment, support for conservation, and environmentally responsible behavior. A model-driven approach was used to develop the instrument, which was analyzed using Item Response Theory and the Rasch dichotomous measurement model. After removal of two items with extremely high difficulty, the instrument was found to be unidimensional and sufficiently reliable. The results of the IRT analyses are interpreted with respect to a modern validity framework. The evaluation portion of this study applied this test instrument to measuring the impact of zoo education programs on 750 fourth through seventh grade students. Qualitative data was collected from program observations and teacher surveys, and a comparison was also made between programs that took place at the zoo, and those that took place in the school classroom, thereby asking questions regarding the role of

    The widespread use of web searches in daily life has allowed researchers to study people's online social and psychological behavior. Using web search data has advantages in terms of data objectivity, ecological validity, temporal resolution, and unique application value. This review integrates existing studies on web search data that have explored topics including sexual behavior, suicidal behavior, mental health, social prejudice, social inequality, public responses to policies, and other psychosocial issues. These studies are categorized as descriptive, correlational, inferential, predictive, and policy evaluation research. The integration of theory-based hypothesis testing in future web search research will result in even stronger contributions to social psychology.

    In The Netherlands, 12-24 years old are over-represented in the total number of traffic fatalities and injuries. In this study, the traffic informer program - designed to promote safe traffic behavior in the pre-driver population - was experimentally evaluated, with a specific focus on bicycle use. Students were subjected to graphic videos of traffic accidents and listened to a first-person narrative provided by a traffic accident victim. The influence of the program on concepts derived from the theory of planned behavior and protection motivation theory (attitudes, norms, self-efficacy, risk-perception, intention and behavior) was assessed. Students from various schools (N=1593;M age=15 years, SD=.84) participated in a quasi-experimental study, either in an experimental or a control group, completing self-report questionnaires one week prior to the program implementation and approximately one month after the program implementation. Mixed regression analyses showed significant positive and negative time × intervention interaction effects on attitude toward traffic violations, relative attitude toward traffic safety, and risk comparison, but not on intention and behavior. More research is needed to find effective behavioral change techniques (other than increasing risk awareness) for promoting safe traffic behavior in adolescents. Research is also needed to address how these can be translated into effective interventions and educational programs. Copyright © 2014 The Authors. Published by Elsevier Ltd.. All rights reserved.

    2017-04-01

    Humans adapt their behavior to their external environment in a process often facilitated by learning. Efforts to describe learning empirically can be complemented by quantitative theories that map changes in neurophysiology to changes in behavior. In this review we highlight recent advances in network science that offer a sets of tools and a general perspective that may be particularly useful in understanding types of learning that are supported by distributed neural circuits. We describe recent applications of these tools to neuroimaging data that provide unique insights into adaptive neural processes, the attainment of knowledge, and the acquisition of new skills, forming a network neuroscience of human learning. While promising, the tools have yet to be linked to the well-formulated models of behavior that are commonly utilized in cognitive psychology. We argue that continued progress will require the explicit marriage of network approaches to neuroimaging data and quantitative models of behavior. Copyright © 2017 Elsevier Ltd.

    This study examines the relationships between perceived parental acceptance and children's behavioral problems (externalizing and internalizing) from a multi-informant perspective. Using mothers, fathers, and children as sources of information, we explore the informant effect and incremental validity. The sample was composed of 681 participants (227 children, 227 fathers, and 227 mothers). Children's (40% boys) ages ranged from 9 to 17 years (M = 12.52, SD = 1.81). Parents and children completed both the Parental Acceptance Rejection/Control Questionnaire (PARQ/Control) and the check list of the Achenbach System of Empirically Based Assessment (ASEBA). Statistical analyses were based on the correlated uniqueness multitrait-multimethod matrix (model MTMM) by structural equations and different hierarchical regression analyses. Results showed a significant informant effect and a different incremental validity related to which combination of sources was considered. A multi-informant perspective rather than a single one increased the predictive value. Our results suggest that mother-father or child-father combinations seem to be the best way to optimize the multi-informant method in order to predict children's behavioral problems based on perceived parental acceptance.

    2012-01-01

    Building on channel complementarity theory and media-system dependency theory, this study explores the impact of conflict-oriented news coverage of health issues on information seeking online. Using Google search data as a measure of behavior, we demonstrate that controversial news coverage of the U.S. Preventive Services Task Force's November 2009 recommendations for changes in breast cancer screening guidelines strongly predicted the volume of same-day online searches for information about mammograms. We also found that this relationship did not exist 1 year prior to the coverage, during which mammography news coverage did not focus on the guideline controversy, suggesting that the controversy frame may have driven search behavior. We discuss the implications of these results for health communication scholars and practitioners.

    Full Text Available Survey method was used and 92 valid questionnaires were collected for the analyses. The results showed that the majority of the rural elder people expressed the need for and attention to health information. ‘‘health service information’’ and ‘‘prevention health care information’’ were the most needed and important. Family, friends and television were the main channels for accessing health information. However, fewer respondents actively sought health information. When health problems occurred, they tended to seek direct medical treatment. This study also found that men were more attentive and active in seeking health information. Respondents over 75 years old rarely concerned about their health information need. People with more education were also more aware of their health information needs and more attentive to information disseminated via mass media. [Article content in Chinese

    The global prevalence of sedentary lifestyles is of grave concern for public health around the world. Moreover, the health risk of sedentary behaviors is of growing interest for researchers, clinicians, and the general public as evidence demonstrates that prolonged amounts of sedentary time increases risk for lifestyle-related diseases. There is a growing trend in the literature that reports how social media can facilitate knowledge sharing and collaboration. Social sites like YouTube facilitate the sharing of media content between users. The purpose of this project was to identify sedentary behavior content on YouTube and describe features of this content that may impact the effectiveness of YouTube for knowledge translation. YouTube was searched on a single day by 3 independent reviewers for evidence-based sedentary behavior content. Subjective data (eg, video purpose, source, and activity type portrayed) and objective data (eg, number of views, comments, shares, and length of the video) were collected from video. In total, 106 videos met inclusion criteria. Videos were uploaded from 13 countries around the globe (ie, Australia, Barbados, Belgium, Canada, Colombia, Kenya, New Zealand, Russia, South Africa, Spain, Ukraine, United Kingdom, United States). The median video length was 3:00 minutes: interquartile range (IQR) 1:44-5:40. On average, videos had been on YouTube for 15.0 months (IQR 6.0-27.5) and had been viewed 239.0 times (IQR 44.5-917.5). Videos had remarkably low numbers of shares (median 0) and comments (median 1). Only 37.7% (40/106) of videos portrayed content on sedentary behaviors, while the remaining 66 videos portrayed physical activity or a mix of behaviors. Academic/health organizations (39.6%, 42/106) and individuals (38.7%, 41/106) were the most prevalent source of videos, and most videos (67.0%, 71/106) aimed to educate viewers about the topic. This study explored sedentary behavior content available on YouTube. Findings demonstrate that

    Full Text Available The lateral habenula (LHb plays a role in a wide variety of behaviors ranging from maternal care, to sleep, to various forms of cognition. One prominent theory with ample supporting evidence is that the LHb serves to relay basal ganglia and limbic signals about negative outcomes to midbrain monoaminergic systems. This makes it likely that the LHb is critically involved in behavioral flexibility as all of these systems have been shown to contribute when flexible behavior is required. Behavioral flexibility is commonly examined across species and is impaired in various neuropsychiatric conditions including autism, depression, addiction, and schizophrenia; conditions in which the LHb is thought to play a role. Therefore, a thorough examination of the role of the LHb in behavioral flexibility serves multiple functions including understanding possible connections with neuropsychiatric illnesses and additional insight into its role in cognition in general. Here we assess the LHb’s role in behavioral flexibility through comparisons of the roles its afferent and efferent pathways are known to play. Additionally, we provide new evidence supporting the LHb contributions to behavioral flexibility through organization of specific goal directed actions under cognitively demanding conditions. Specifically, in the first experiment, a majority of neurons recorded from the LHb were found to correlate with velocity on a spatial navigation task and did not change significantly when reward outcomes were manipulated. Additionally, measurements of local field potential in the theta band revealed significant changes in power relative to velocity and reward location. In a second set of experiments, inactivation of the LHb with the GABA agonists baclofen and muscimol led to an impairment in a spatial/response based repeated probabilistic reversal learning task. Control experiments revealed that this impairment was likely due to the demands of repeated switching

    Understanding the preferred sources of health-related information among patients with cancer is essential for designing successful cancer education and prevention strategies. However, little is known about health-related information-seeking practices among patients living in low- and middle-income countries. We studied the preferred sources of health-related information among Mexican patients with cancer and explored which factors influence these choices. The health-related information-seeking practices among patients with cancer treated at a public hospital in Mexico City were evaluated using questions from the Spanish Version of the Health Information National Trends Survey. The characteristics of patients who sought health-related information, and of those who chose the internet as their preferred source of information, were analyzed. Fisher's exact test and logistic regression were used for statistical analyses. One hundred forty-eight patients answered the survey (median age 60 years, 70% female), of which 88 (59%) had sought for health-related information. On multivariate analysis, the only characteristic associated with lower odds of seeking health-related information was increasing age (OR 0.93, 95% CI 0.90-0.97). Sixty-one respondents (69%) listed the internet as their preferred source of health-related information. On multivariate analysis, only being of the female gender (OR 4.9, 95% CI 1.3-18.3) was related with higher odds of preferring other sources of information over the internet. Among Mexican patients with cancer, the Internet is the most widely used information source. Older age was the characteristic most strongly associated with not seeking health-related information, while being female was strongly associated with preferring other sources of information over the Internet.

    The aim of this study is to investigate the relationship between five domain-specific skills of health literacy: Find Health Information (FHI), Appraise Health Information (AHI), Understand Health Information to act (UHI), Actively Manage One's Health (AMH), and E-health literacy (e-Heals), and health information seeking behaviors and three categories of health outcomes. A survey was implemented and data was collected from 1062 college going adults and analyzed using bivariate tests and multiple regression analysis. Among the five domain-specific Health Literacy skills, AHI and e-Heals were significantly associated with the use of traditional sources and the Internet for healthcare information respectively. Similarly and AMH and e-Heals were significantly associated with the use of traditional sources and the Internet for health lifestyle information respectively. Lastly AHI, AMH and e-Heals were significantly associated with the three categories of outcomes, and AFH was significantly associated with cognitive and instrumental outcomes, but not doctor-patient communication outcomes. Consumers' ability to use different health sources for both healthcare and health lifestyle information, and the three categories of health outcomes are associated with different domain-specific health literacy skills. Health literacy initiatives may be improved by focusing on clients to develop domain-specific skills that increase the likelihood of using health information sources and accrue benefits.

    Multiple sclerosis (MS) patients and their family members increasingly seek health information on the Internet. There has been little exploration of how MS patients integrate health information with their needs, preferences, and values for decision making. The INtegrating and Deriving Evidence, Experiences, and Preferences (IN-DEEP) project is a collaboration between Italian and Australian researchers and MS patients, aimed to make high-quality evidence accessible and meaningful to MS patients and families, developing a Web-based resource of evidence-based information starting from their information needs. The objective of this study was to analyze MS patients and their family members' experience about the Web-based health information, to evaluate how they asses this information, and how they integrate health information with personal values. We organized 6 focus groups, 3 with MS patients and 3 with family members, in the Northern, Central, and Southern parts of Italy (April-June 2011). They included 40 MS patients aged between 18 and 60, diagnosed as having MS at least 3 months earlier, and 20 family members aged 18 and over, being relatives of a person with at least a 3-months MS diagnosis. The focus groups were audio-recorded and transcribed verbatim (Atlas software, V 6.0). Data were analyzed from a conceptual point of view through a coding system. An online forum was hosted by the Italian MS society on its Web platform to widen the collection of information. Nine questions were posted covering searching behavior, use of Web-based information, truthfulness of Web information. At the end, posts were downloaded and transcribed. Information needs covered a comprehensive communication of diagnosis, prognosis, and adverse events of treatments, MS causes or risk factors, new drugs, practical, and lifestyle-related information. The Internet is considered useful by MS patients, however, at the beginning or in a later stage of the disease a refusal to actively search

    Parent and teacher ratings of child behaviors are often discrepant, and these discrepancies may be correlated with parenting stress. The present study explored whether various parenting stress factors are associated with discrepancies between parent and teacher ratings of attention-deficit/hyperactivity disorder and oppositional defiant disorder (ODD) as well as internalizing symptoms in preschool children. We recruited 299 Taiwanese preschool children (aged 4–6 years) from the community or via clinical referrals. A structural equation modeling was used to analyze the relationships among three factors derived from the Parenting Stress Index-Short Form and informant discrepancies on symptoms of inattention, hyperactivity/impulsivity, ODD, and internalizing behaviors. Scores reported by parents were higher for each of the symptoms examined than those reported by teachers, and the degree of agreement between informants ranged from low to moderate. The parental distress factor of parenting stress was associated only with parent ratings, whereas other factors of parenting stress—parent-child dysfunctional interaction and parents’ stress resulted from their child’s temperament—were correlated with both parent and teacher ratings. Only parental distress factor predicted informant discrepancies for all behavioral symptoms assessed. Our findings suggest that parental distress should be considered when parent rating scores show significant discrepancies from that of teacher rating scores. PMID:29016602

    To assist suicide prevention we need a better understanding of how suicidal individuals act in their environment, and the online world offers an ideal opportunity to examine daily behaviors. This anonymous survey (N = 1,016) provides first-of-its-kind empirical evidence demonstrating suicide-risk people (n = 290) are unique in their online behaviors. Suicidal users reported more time online, greater likelihood of developing online personal relationships, and greater use of online forums. In addition, suicide-risk women reported more time browsing/surfing and social networking. The authors conclude that suicide prevention efforts should respond to suicide-risk users' greater demands for online interpersonal communications.

    The Internet is viewed as an important source for health information and a medium for patient empowerment. However, little is known about how seniors use the Internet in relation to other sources for health information. The aim was to determine which information resources seniors who use the Internet use and trust for health information, which sources are preferred, and which sources are used by seniors for different information needs. Questions from published surveys were selected based on their relevance to the study objectives. The Autonomy Preference Index was used to assess information needs and preferences for involvement in health decisions. Invitation to participate in this online survey was sent to the email list of a local senior organization (298 addresses) in the Netherlands. There were 118 respondents with a median age of 72 years (IQR 67-78 years). Health professionals, pharmacists, and the Internet were the most commonly used and trusted sources of health information. Leaflets, television, newspapers, and health magazines were also important sources. Respondents who reported higher use of the Internet also reported higher use of other sources (Pseniors who use the Internet, the Internet was a preferred source of health information. Seniors who report higher use of the Internet also report higher use of other information resources and were also the primary consumers of paper-based resources. Respondents most frequently searched for health information after an appointment rather than to prepare for an appointment. Resources used varied by health topic. Future research should seek to confirm these findings in a general elderly population, investigate how seniors seek and understand information on the Internet, and investigate how to reach seniors who prefer not to use the Internet for health information.

    2017-09-01

    We proposed a conceptual model to predict health information-seeking behaviors (HISBs) from three different sources (family, the Internet, doctors). To test the model, a structural equation modeling (SEM) analysis was conducted using data from the 2012 Annenberg National Health Communication Survey (ANHCS) (N = 3,285). Findings suggest higher social support from family predicts higher trust in health information from family members (abbreviated as trust in this article). Trust is positively related to HISBs from all three sources, with the path linking trust to HISB from family being the strongest. The effect of social support on HISB from family is partially mediated by trust, while effect of social support on HISBs from the Internet/doctors is fully mediated by trust. Implications of the study are discussed.

    Full Text Available Increasingly, whales and dolphins are the focus of tourism activities in many coastal locations. Although these activities can affect individuals and populations of cetaceans, the biological significance and hence the cost of these impacts are as yet largely unknown. This study assessed the effects of boat interactions on the behavioral budget of two populations of bottlenose dolphins (Tersiops truncatus living in similar fjords but exposed to different levels of tourism activities. This comparison makes it possible to assess the costs of short-term avoidance strategies and the threshold at which those strategies are no longer effective. The effects of boat interactions were the same in both fjords. The resting state was the most sensitive to interactions; socializing was less sensitive. Short-term displacement was a typical response to boat exposure: dolphins were more likely to travel after an interaction with a vessel. Although the behavioral budgets of these populations were significantly altered during interactions with boats, their overall behavioral budgets were unchanged. Dolphins in Milford Sound actively avoided boat interactions, possibly to maintain their overall behavioral budget unchanged. This active avoidance led to avoidance of the area. Characteristics of dolphin-boat interactions in Milford Sound suggest that the advantages gained by short-term avoidance are lost if, on average, fewer than 68 min elapse between successive interactions with boats. If dolphin-boat interactions were more frequent than this, the dolphins switched to a longer-term response: area avoidance.

    2016-01-01

    Background Laypeople increasingly use the Internet as a source of health information, but finding and discovering the right information remains problematic. These issues are partially due to the mismatch between the design of consumer health websites and the needs of health information seekers, particularly the lack of support for “exploring” health information. Objective The aim of this research was to create a design for consumer health websites by supporting different health information–seeking behaviors. We created a website called Better Health Explorer with the new design. Through the evaluation of this new design, we derive design implications for future implementations. Methods Better Health Explorer was designed using a user-centered approach. The design was implemented and assessed through a laboratory-based observational study. Participants tried to use Better Health Explorer and another live health website. Both websites contained the same content. A mixed-method approach was adopted to analyze multiple types of data collected in the experiment, including screen recordings, activity logs, Web browsing histories, and audiotaped interviews. Results Overall, 31 participants took part in the observational study. Our new design showed a positive result for improving the experience of health information seeking, by providing a wide range of information and an engaging environment. The results showed better knowledge acquisition, a higher number of page reads, and more query reformulations in both focused and exploratory search tasks. In addition, participants spent more time to discover health information with our design in exploratory search tasks, indicating higher engagement with the website. Finally, we identify 4 design considerations for designing consumer health websites and health information–seeking apps: (1) providing a dynamic information scope; (2) supporting serendipity; (3) considering trust implications; and (4) enhancing interactivity

  6. The rules of information aggregation and emergence of collective intelligent behavior

    International Nuclear Information System (INIS)

    Bettencourt, Luis

    2008-01-01

    Information is a peculiar quantity. Unlike matter or energy, the aggregation of knowledge from many individuals can in fact produce more (or less) information than the sum of its parts. We use the formalism of information theory to derive general principles of information aggregation and collective organization under which information pooling can be synergetic or to identify when it will be redundant. We then show how several problems of collective cognition and coordination can be understood in terms of the conditions that allow for the minimization of uncertainty (maximization of predictability) under information pooling over many individuals. We discuss in some detail how collective coordination in swarms, markets, language processing and collaborative filtering may be guided by the optimal aggregation of information over many sources and identify circumstances when these processes fail, leading e.g. to inefficient markets. The contrast to approaches to understand coordination and collaboration via traditional decision and game theory is discussed as well as the incentives to individuals and groups to find optimal information aggregation mechanisms.

    Middle-income countries are in need of research that uses theoretical-based models to assess factors that predict adherence to antiretroviral therapy (ART) and help in the design, implementation, and evaluation of interventions for nonadherent populations. In Mexico, the Information and Motivation and Behavioral Skills (IMB) Model of ART Adherence constructs is useful in describing and predicting adherence behaviors in various samples but has not been articulated to people living with HIV (PLWH) on ART. The aim of this was to characterize the IMB core constructs and identify correlates of ART adherence in an HIV-positive clinic sample in Mexico. A convenience sample of 109 HIV-positive patients attending their monthly visits at a local public hospital were interviewed with the Spanish version of the LifeWindows IMB ART Adherence Questionnaire (LW-IMB-AAQ) as well as a sociodemographic questionnaire. All participants were recruited from a hospital-based outpatient clinical care site. Partial confirmation of the relationships proposed by the IMB Model of ART Adherence was found. As predicted by the model, only behavioral skills had direct association with all measures of self-reported adherence, and motivation was associated with behavioral skills. Information did not demonstrate significant relations to either motivation or behavioral skills, nor did it directly associate with adherence. Self-reported adherence did not associate with CD4 counts, nor did any of the IMB model core constructs. Applicability of the IMB Model of ART Adherence in this setting is discussed. The IMB Model of ART Adherence offered promise in this population and could help tailor population-specific interventions to promote high rates of ART adherence. © The Author(s) 2015.

    To understand how rural and urban patients seek medical service information in Sichuan province. A self-designed questionnaire was distributed randomly to patients who visited primary,secondary and tertiary health facilities in Chengdu,Yibin and Suining,collecting data in relation to their sources of medical service information,as well as the contents and credibility of the information. The major sources of medical service information came from friends,past experiences and television programs,which were consistent with the most desirable access channels. The urban patients were more likely to trust (5.3%) and use (10.6%) the Internet to obtain medical service information compared with their rural counterparts (3.4% and 5.5%,respectively, P marketing strategies for urban and rural patients should be developed to channel patients to appropriate health facilities.

    Strategies that provide information about the environmental impact of activities are increasingly seen as effective to encourage conservation behavior. This article offers the most comprehensive meta-analysis of information based energy conservation experiments conducted to date. Based on evidence from 156 published field trials and 525,479 study subjects from 1975 to 2012, we quantify the energy savings from information based strategies. On average, individuals in the experiments reduced their electricity consumption by 7.4%. Our results also show that strategies providing individualized audits and consulting are comparatively more effective for conservation behavior than strategies that provide historical, peer comparison energy feedback. Interestingly, we find that pecuniary feedback and incentives lead to a relative increase in energy usage rather than induce conservation. We also find that the conservation effect diminishes with the rigor of the study, indicating potential methodological issues in the current literature. - Highlights: • We conduct a meta-analysis of information-based energy conservation experiments. • We analyze 156 published trials and 524,479 study subjects from 1975 to 2012. • On average, individuals in the experiments reduced electricity consumption by 7.4%. • Individualized feedback via audits and consulting results in the largest reductions. Pecuniary feedback and incentives lead to a relative increase in energy usage

    The goal of our study was to evaluate the extent of disease-related knowledge and the need for further information of cancer patients in Greece. We evaluated 203 mentally competent adult cancer patients hospitalized in general and oncological hospitals in the city of Athens and its suburbs. Data were collected by means of semistructured interviews. Patients were evaluated as to whether they had awareness of their diagnosis. Those who did so (n = 83) were further questioned about additional disease-related information. The majority of patients (59%) claimed to have no knowledge of their diagnosis. Women (p = 0.004) as well as high school and university graduates (p = 0.024) showed significantly superior levels of information when compared to men and graduates of elementary schools, respectively. Age was also a factor that influenced the level of the awareness of the diagnosis and the request for additional information: patients who were informed about the diagnosis and patients who asked for more information were significantly younger than their counterparts who ignored the diagnosis (p family beliefs, "mind-set" difficulties, and organizational issues should not become barriers to the patients' right to be fully informed of their diagnoses and choices of potential therapies.

  11. UNDERSTANDING THE SUBJECT´S BEHAVIOR IN THE INTERACTION WITH A DECISION SUPPORT SYSTEM UNDER TIME PRESSURE AND MISSING INFORMATION

    Full Text Available The article seeks to determine how time pressure and missing information in decision-making affect the behavior of decision makers. Data was collected through an experimental task of simulating the purchase of a car, which was structured with the AHP (Analytic Hierarchy Process multi-criteria method in a Decision Support System. When pressured by time, the experimental subjects focused on the car of their choice; whereas with no time pressure, some of them rationalized more, used the information, and did not agree with the chosen car. Assumptions of the Theory of Image justified some findings, indicating that previously structured images in the mind of the decision maker are a way to cope with time pressure. Given the missing information, the use of background knowledge and individual experience were the most prominent coping strategy.

    Neither men with erectile dysfunction (ED) nor their physicians are willing to discuss sexual problem sufficiently. Written information material could facilitate a dialogue and encourage men to seek treatment. The central task of this article was to determine the effectiveness and acceptance of patient information material for sexual dysfunction. Through an information campaign, men received informational material. Eight thousand men also received a first survey, which asked about the intention to seek treatment and to discuss the sexual problem with a physician or partner. A second follow-up questionnaire, 3-6 months after the first one, asked for the implementation of these intentions. Descriptive and regression-based analyses were applied. Help-seeking behavior, subjective assessment of change in disease severity and partnership quality, satisfaction. Four hundred forty-three men participated in both surveys. Nearly 90% of them became active after reading the information material. More than half talked with their partner (57.8%) and a physician (65%), and one-third sought treatment (31.8%). Especially discussing the problem with the partner and receiving treatment improved erectile functioning and led to an increase in the quality of partnership (P information material is a useful resource for men with ED, because it evokes a high help-seeking behavior. It was perceived both to improve the sexual problem as well as to increase the quality of partnership. Providing such material in the medical practice may be an appropriate way to overcome inhibitions and to initiate dialogue with affected men. However, the results must be interpreted with caution because of possible motivationally driven self

    There are a variety of resources to obtain health information, but few studies have examined if main and allied health professionals prefer different methods. The current study was to investigate their information-searching behaviours. A constructed questionnaire survey was conducted from January through April 2011 in nationwide regional hospitals of Taiwan. Questionnaires were mailed to main professionals (physicians and nurses) and allied professionals (pharmacists, physical therapists, technicians and others), with 6160 valid returns collected. Among all professional groups, the most commonly used resource for seeking health information was a Web portal, followed by colleague consultations and continuing education. Physicians more often accessed Internet-based professional resources (online databases, electronic journals and electronic books) than the other groups (P < 0.05). In contrast, physical therapists more often accessed printed resources (printed journals and textbooks) than the other specialists (P < 0.05). And nurses, physical therapists and technicians more often asked colleagues and used continuing education than the other groups (P < 0.01). The most commonly used online database was Micromedex for pharmacists and MEDLINE for physicians, technicians and physical therapists. Nurses more often accessed Chinese-language databases rather than English-language databases (P < 0.001). This national survey depicts the information-searching pattern of various health professionals. There were significant differences between and within main and allied health professionals in their information searching. The data provide clinical implications for strategies to promote the accessing of evidence-based information. © 2012 John Wiley & Sons Ltd.

  16. Manifestations of Personality in Online Social Networks: Self-Reported Facebook-Related Behaviors and Observable Profile Information

    2011-01-01

    Abstract Despite the enormous popularity of Online Social Networking sites (OSNs; e.g., Facebook and Myspace), little research in psychology has been done on them. Two studies examining how personality is reflected in OSNs revealed several connections between the Big Five personality traits and self-reported Facebook-related behaviors and observable profile information. For example, extraversion predicted not only frequency of Facebook usage (Study 1), but also engagement in the site, with extraverts (vs. introverts) showing traces of higher levels of Facebook activity (Study 2). As in offline contexts, extraverts seek out virtual social engagement, which leaves behind a behavioral residue in the form of friends lists and picture postings. Results suggest that, rather than escaping from or compensating for their offline personality, OSN users appear to extend their offline personalities into the domains of OSNs. PMID:21254929

    In this paper we analyze the contrary behaviors of the informed investors and uniformed investors, and then construct a competition model with two groups of agents, namely agents who intend to stay in minority and those who intend to stay in majority. We find two kinds of competitions, inter- and intra-groups. The model shows periodic fluctuation feature. The average distribution of strategies illustrates a prominent central peak which is relevant to the peak-fat-tail character of price change distribution in stock markets. Furthermore, in the modified model the tolerance time parameter makes the agents diversified. Finally, we compare the strategies distribution with the price change distribution in real stock market, and we conclude that contrary behavior rules and tolerance time parameter are indeed valid in the description of market model.

    Emotionally salient information is well attended and remembered. It has been shown that infatuated individuals have increased attention for their beloved. It is unknown whether this attention bias generalizes to information related to the beloved. Moreover, infatuated individuals report to remember trivial things about their beloved, but this has not yet been tested empirically. In two studies, we tested whether infatuated individuals have increased attention and memory for beloved-related information. In a passive viewing task (Study 1), the late positive potential, an event-related potential (ERP) component reflecting motivated attention, was enhanced for beloved-related vs friend-related words/phrases. In a recognition task (Study 2), memory performance and the frontal and parietal ERP old/new effects, reflecting familiarity and recollection, respectively, were not enhanced for beloved-related compared with friend-related words/phrases. In free recall tasks in both studies, memory was better for beloved-related than friend-related words/phrases. This research reveals that attention and memory are enhanced for beloved-related information. These attention and memory biases for beloved-related information were not due to valence, semantic relatedness, or experience, but to arousal. To conclude, romantic love has profound effects on cognition that play a clear role in daily life. © The Author (2014). Published by Oxford University Press.

    2013-10-01

    Life in modern societies implies a close relationship with many types of devices. The diversity of such devices has impact in diverse areas of our life as some provide support for management tasks, others just provide information, and most of them follow us anywhere and anytime. The more widespread example is mobile phones, but others also follow us, like our music devices or even our car with many electronic systems. In a recent past a phone was something to talk with others and a car was just a vehicle, with an engine, to allow displacement of people and goods. A phone would support voice conversation and a car had the equipment needed to take us to some destination. But these days all those devices and vehicles have computer equipment and some include complex functions and sensory abilities. We cannot question how useful those devices are for every day's activities but it is questionable how those devices respect our nature and address our needs of perceptive and emotive human beings. How far can those devices retrieve information about our nature, and our feelings, and what kind of information and reasoning those devices can provide to users? The proposed framework, by capturing and managing sensorial and physiological information, will feed information that enable the reasoning of emotional knowledge in an IoT environment.

    This article describes ( a) parent questions about ADHD (attention deficit/hyperactivity disorder), ( b) parent Internet use to seek ADHD information, and ( c) associations between type of Internet access and ADHD information-seeking. Seventy parents of children (ages 7-17 years) with ADHD completed questionnaires after their child's visit with their pediatrician. Bivariate relationships were assessed using chi-square statistics, Pearson correlation coefficients, or t tests. Parents identified an average of 8.9 questions about ADHD for their child's provider. Common questions were related to medication and long-term implications of ADHD. A majority of parents searched the Internet for general ADHD information (87%) and ADHD medication information (81%). White parents accessed the Internet significantly more via home computer, mobile phone, and tablet, and significantly less via public library than non-White parents. Parents who accessed the Internet via home computers and tablets were more likely to search the Internet for ADHD medication information than parents who did not.

    This study adopts a global theoretical framework to predict adolescents' disclosure of personal information in exchange for incentives offered by commercial Websites. The study postulates and tests the validity of a model based on the theory of planned behavior (TPB), including antecedent factors of attitude and perceived behavioral control (PBC). A survey was conducted among 1,042 respondents. Results from SEM analyses show that the hypothesized model fits the empirical data well. The model accounts for 61.9 percent of the variance in adolescents' intention to disclose and 43.7 percent of the variance in self-reported disclosure. Perceived social pressure exerted by significant others (subjective norm) is the most important TPB factor in predicting intention to disclose personal information in exchange for incentives. This finding suggests that in discussions of adolescents' information privacy, the importance of social factors outweighs the individually oriented TPB factors of attitude and PBC. Moreover, privacy concern and trust propensity are significant predictors of respondents' attitudes toward online disclosure in exchange for commercial incentives, whereas the frequency of Internet use significantly affects their level of PBC.

    Parents, peers and media are informal sources of sexual information for adolescents. Although the content of sexual information communicated by these sources is known to vary, little is known about what adolescents report actually learning from each source. Data from 1,990 U.S.14-17-year-olds who participated in an online survey in 2015 were used to assess learning about four topics (sex, condoms, hormonal birth control and romantic relationships) from three informal sources (parents, peers, and television and movies). Gender and race differences in learning by source and topic were assessed using t tests. Following a factor analysis, learning about all topics was grouped by source, and regression analyses were conducted to examine associations between learning from each source and three outcomes: sexual activity, condom use and hormonal birth control use. Models included interactions between information sources and race and gender. White adolescents reported learning more from parents and less from media than black adolescents. Compared with males, females learned more about hormonal birth control and less about condoms from their parents, and more about relationships from peers and media. Learning from parents and from peers were positively associated with adolescents' sexual activity (unstandardized coefficients, 0.26 and 0.52, respectively). Learning from parents was positively associated with condom use (odds ratio, 1.5). Adolescents' learning about sex from informal sources varies by race and gender. Future research should examine whether sexual health interventions and message development can capitalize on these differences. Copyright © 2018 by the Guttmacher Institute.

    We formulate a general model for the growth of scale-free networks under filtering information conditions--that is, when the nodes can process information about only a subset of the existing nodes in the network. We find that the distribution of the number of incoming links to a node follows a universal scaling form, i.e., that it decays as a power law with an exponential truncation controlled not only by the system size but also by a feature not previously considered, the subset of the network 'accessible' to the node. We test our model with empirical data for the World Wide Web and find agreement

    This study investigated pupillary and behavioral responses to an emotional word valence identification paradigm among 32 pre-/early pubertal and 34 mid-/late pubertal typically developing children and adolescents. Participants were asked to identify the valence of positive, negative, and neutral words while pupil dilation was assessed using an eyetracker. Mid-/late pubertal children showed greater peak pupillary reactivity to words presented during the emotional word identification task than pre-/early pubertal children, regardless of word valence. Mid-/late pubertal children also showed smaller sustained pupil dilation than pre-/early pubertal children after the word was no longer on screen. These findings were replicated controlling for participants' age. In addition, mid-/late pubertal children had faster reaction times to all words, and rated themselves as more emotional during their laboratory visit compared to pre-/early pubertal children. Greater recall of emotional words following the task was associated with mid-/late pubertal status, and greater recall of emotional words was also associated with higher peak pupil dilation. These results provide physiological, behavioral, and subjective evidence consistent with a model of puberty-specific changes in neurobehavioral systems underpinning emotional reactivity.

    2017-09-01

    A large body of research finds that unstructured socializing with peers is positively associated with delinquency during adolescence. Yet, existing research has not ruled out the potential for confounding due to genetic factors and factors that can be traced to environments shared between siblings. To fill this void, the current study examines whether the association between unstructured socializing with peers and delinquent behavior remains when accounting for genetic factors, shared environmental influences, and a variety of non-shared environmental covariates. We do so by using data from the twin subsample of the National Longitudinal Study of Adolescent to Adult Health (n = 1200 at wave 1 and 1103 at wave 2; 51% male; mean age at wave 1 = 15.63). Results from both cross-sectional and lagged models indicate the association between unstructured socializing with peers and delinquent behavior remains when controlling for both genetic and environmental influences. Supplementary analyses examining the association under different specifications offer additional, albeit qualified, evidence supportive of this finding. The study concludes with a discussion highlighting the importance of limiting free time with friends in the absence of authority figures as a strategy for reducing delinquency during adolescence.

  11. Interplay between the local information based behavioral responses and the epidemic spreading in complex networks.

    The spreading of an infectious disease can trigger human behavior responses to the disease, which in turn plays a crucial role on the spreading of epidemic. In this study, to illustrate the impacts of the human behavioral responses, a new class of individuals, S(F), is introduced to the classical susceptible-infected-recovered model. In the model, S(F) state represents that susceptible individuals who take self-initiate protective measures to lower the probability of being infected, and a susceptible individual may go to S(F) state with a response rate when contacting an infectious neighbor. Via the percolation method, the theoretical formulas for the epidemic threshold as well as the prevalence of epidemic are derived. Our finding indicates that, with the increasing of the response rate, the epidemic threshold is enhanced and the prevalence of epidemic is reduced. The analytical results are also verified by the numerical simulations. In addition, we demonstrate that, because the mean field method neglects the dynamic correlations, a wrong result based on the mean field method is obtained-the epidemic threshold is not related to the response rate, i.e., the additional S(F) state has no impact on the epidemic threshold.

Aim of this study was to evaluate and interpret web search queries for terms related to movement disorders (MD) in English-speaking countries and their changes over time. We analyzed information regarding the volume of online searches in Google and Wikipedia for the most common MD and their treatments. We determined the highest search volume peaks to identify possible relation with online news headlines. The volume of searches for some queries related to MD entered in Google enormously increased over time. Most queries were related to definition, subtypes, symptoms and treatment (mostly to adverse effects, or alternatively, to possible alternative treatments). The highest peaks of MD search queries were temporally related to news about celebrities suffering from MD, to specific mass-media events or to news concerning pharmaceutic companies or scientific discoveries on MD. An increasing number of people use Google and Wikipedia to look for terms related to MD to obtain information on definitions, causes and symptoms, possibly to aid initial self-diagnosis. MD information demand and the actual prevalence of different MDs do not travel together: web search volume may mirrors patients' fears and worries about some particular disorders perceived as more serious than others, or may be driven by release of news about celebrities suffering from MD, "breaking news" or specific mass-media events regarding MD.

    We study the energy-level crossing behavior in a two-dimensional quantum well with the Rashba and Dresselhaus spin-orbit couplings (SOCs). By mapping the SOC Hamiltonian onto an anisotropic Rabi model, we obtain the approximate ground state and its quantum Fisher information (QFI) via performing a unitary transformation. We find that the energy-level crossing can occur in the quantum well system within the available parameters rather than in cavity and circuit quantum eletrodynamics systems. Furthermore, the influence of two kinds of SOCs on the QFI is investigated and an intuitive explanation from the viewpoint of the stationary perturbation theory is given.

  5. A review of the neural and behavioral consequences for unitizing emotional and neutral information

    Full Text Available A special type of association, called a unitization, is formed when pieces of information are encoded as a single representation in memory (e.g., shirt and blue are encoded as a blue shirt; Graf & Schacter, 1989 and typically are later reactivated in memory as a single unit, allowing access to the features of multiple related stimuli at once (Bader et al., 2010; Diana et al., 2011. This review examines the neural processes supporting memory for unitizations and how the emotional content of the material may influence unitization. Although associative binding is typically reliant on hippocampal processes and supported by recollection, the first part of this review will present evidence to suggest that when two items are unitized into a single representation, memory for those bound items may be accomplished on the basis of familiarity and without reliance on the hippocampus. The second part of this review discusses how emotion may affect the processes that give rise to unitizations. Emotional information typically receives a mnemonic benefit over neutral information, but the literature is mixed on whether the presence of emotional information impedes or enhances the associative binding of neutral information (reviewed by Mather, 2007. It has been suggested that the way the emotional and neutral details are related together may be critical to whether the neutral details are enhanced or impeded (Mather, 2007; Mather & Sutherland, 2011. We focus on whether emotional arousal aides or inhibits the creation of a unitized representation, presenting preliminary data and future directions to test empirically the effects of forming and retrieving emotional and neutral unitizations.

    The Internet has become an established source of health information for people seeking health information. In recent years, research on the health information seeking behavior of Internet users has become an increasingly important scholarly focus. However, there have been no long-term bibliometric studies to date on Internet health information seeking behavior. The purpose of this study was to map publication trends and explore research hot spots of Internet health information seeking behavior. A bibliometric analysis based on PubMed was conducted to investigate the publication trends of research on Internet health information seeking behavior. For the included publications, the annual publication number, the distribution of countries, authors, languages, journals, and annual distribution of highly frequent major MeSH (Medical Subject Headings) terms were determined. Furthermore, co-word biclustering analysis of highly frequent major MeSH terms was utilized to detect the hot spots in this field. A total of 533 publications were included. The research output was gradually increasing. There were five authors who published four or more articles individually. A total of 271 included publications (50.8%) were written by authors from the United States, and 516 of the 533 articles (96.8%) were published in English. The eight most active journals published 34.1% (182/533) of the publications on this topic. Ten research hot spots were found: (1) behavior of Internet health information seeking about HIV infection or sexually transmitted diseases, (2) Internet health information seeking behavior of students, (3) behavior of Internet health information seeking via mobile phone and its apps, (4) physicians' utilization of Internet medical resources, (5) utilization of social media by parents, (6) Internet health information seeking behavior of patients with cancer (mainly breast cancer), (7) trust in or satisfaction with Web-based health information by consumers, (8

    To evaluate self-monitoring of blood glucose (SMBG) information deficits, motivational obstacles, and behavioral skills limitations in individuals with type 1 and type 2 diabetes, and to assess the relationship of these deficits with SMBG frequency. Individuals with type 1 (n = 208; 103 male, 105 female) and type 2 (n = 218; 107 male, 111 female) diabetes participated in an online survey assessing SMBG information, motivation, behavioral skills, and behavior. A substantial proportion of participants scored as SMBG uninformed, unmotivated, and unskilled on specific assessment items. SMBG information, motivation, and behavioral skills deficits were significantly correlated with SMBG frequency, such that individuals with type 1 or type 2 diabetes, who were less informed, less motivated, and less behaviorally skilled, reported lower frequency of SMBG. Common and consequential SMBG information, motivation, and behavioral skills deficits were present, and patients with these gaps were less likely to test frequently. Clinical education focusing on relevant SMBG information, motivation to act, and behavioral skills for acting effectively may be a priority.

    Two studies examined interventions to increase the frequency of gratitude expression among college students in two large lecture classes of an Introduction to Psychology course at a large university in southwest Virginia. Both studies evaluated the impact of a writing exercise designed to increase intentions to express gratitude in a prescribed manner. In addition, participants in both studies were given one week to express gratitude to people who performed prosocial behavior. Gratitude expression was assessed by self-report on a survey administered during the psychology class. In both studies, intentions to thank another person for a kind act were significantly higher in the Intervention class than in the Control class, but self-reported expressions of gratitude were significantly higher in the Control class than in the Intervention class. This was an unexpected "countercontrol effect." Directions for future research are discussed, as well as theoretical/methodological explanations.

    This study explored the multitasking information behaviour of Web users and how this is influenced by working memory, flow and Personal, Artefact and Task characteristics, as described in the PAT model. The research was exploratory using a pragmatic, mixed method approach. Thirty University students participated; 10 psychologists, 10 accountants and 10 mechanical engineers. The data collection tools used were: pre and post questionnaires, a working memory test, a flow state scale test, audio-visual data, web search logs, think aloud data, observation, and the critical decision method. All participants searched information on the Web for four topics: two for which they had prior knowledge and two more without prior knowledge. Perception of task complexity was found to be related to working memory. People with low working memory reported a significant increase in task complexity after they had completed information searching tasks for which they had no prior knowledge, this was not the case for tasks with prior knowledge. Regarding flow and task complexity, the results confirmed the suggestion of the PAT model (Finneran and Zhang, 2003), which proposed that a complex task can lead to anxiety and low flow levels as well as to perceived challenge and high flow levels. However, the results did not confirm the suggestion of the PAT model regarding the characteristics of web search systems and especially perceived vividness. All participants experienced high vividness. According to the PAT model, however, only people with high flow should experience high levels of vividness. Flow affected the degree of change of knowledge of the participants. People with high flow gained more knowledge for tasks without prior knowledge rather than people with low flow. Furthermore, accountants felt that tasks without prior knowledge were less complex at the end of the web seeking procedure than psychologists and mechanical engineers. Finally, the three disciplines appeared to differ

    2011-01-01

    Editors’ preface The management of chronic low back pain (CLBP) has proven very challenging in North America, as evidenced by its mounting socioeconomic burden. Choosing amongst available non-surgical therapies can be overwhelming for many stakeholders, including patients, health providers, policy makers, and third-party payers. Although all parties share a common goal and wish to use limited healthcare resources to support interventions most likely to result in clinically meaningful improvements, there is often uncertainty about the most appropriate intervention for a particular patient. To help understand and evaluate the various commonly used non-surgical approaches to CLBP, the North American Spine Society has sponsored this supplement to The Spine Journal, titled Evidence informed management of chronic low back pain without surgery. Articles in this supplement were contributed by leading spine practitioners and researchers, who were invited to summarize the best available evidence for a particular intervention and encouraged to make this information accessible to non-experts. Each of the articles contains five sections (description, theory, evidence of efficacy, harms, and summary) with common subheadings to facilitate comparison across the 24 different interventions profiled in this supplement, blending narrative and systematic review methodology as deemed appropriate by the authors. It is hoped that articles in this supplement will be informative and aid in decision making for the many stakeholders evaluating non-surgical interventions for CLBP. PMID:18164452

    This study examines how different information sources relate to Health Belief Model constructs, hepatitis B virus (HBV) knowledge, and HBV screening. The Maryland Asian American Liver Cancer Education Program administered a survey of 877 Asian immigrants. The most common sources of information identified by the multiple-answer questions were newspapers (39.8 %), physicians (39.3 %), friends (33.8 %), TV (31.7 %), and the Internet (29.5 %). Path analyses-controlling for age, sex, educational level, English proficiency, proportion of life in U.S., health insurance coverage, and family history of HBV infection-showed that learning about HBV from physicians had the strongest direct effect; friends had a marginal indirect effect. Perceived risk, benefits, and severity played limited roles in mediation effects. Path analysis results differed by ethnicity. Physician-based HBV screening intervention would be effective, but should be complemented with community health campaigns through popular information sources for the uninsured.

    To gain a better understanding of electronic cigarette (e-cigarette) use behavior and experience among adult e-cigarette users, with the goal of informing development of future e-cigarette use measures. Between August and October 2014 six focus groups were conducted in Seattle. Participants (63% male; 60% >35 years old; 60% White): e-cigarette users who used combustible tobacco products either currently or in the past. E-cigarette discussion topics covered: their daily use pattern (eg, frequency), product-related characteristics (eg, nicotine levels), and perceptions about health risks and benefits. Participants' descriptions of daily use were so varied that no common "unit" of a "session" easily summarized frequency or quantity of typical e-cigarette use. Most users had difficulty in tracking their own use. Participants reported nicotine craving relief when using e-cigarettes, but described e-cigarettes use as less satisfying than combustible cigarettes. Valued characteristics included "ready availability" and the possibility of using indoors. A unique aspect of the e-cigarette use experience is the option of adding flavors and having the ability to exhale "big clouds" of vapor/aerosol. Most perceived e-cigarettes as a better and safer alternative to conventional cigarettes, yet still sought further information about health consequences and safety of e-cigarettes from trusted sources. E-cigarettes users are far from homogeneous in their behavior and motivation for adopting e-cigarettes. A range of use patterns arising from both hedonic and utilitarian factors, along with product characteristics (eg, variable nicotine levels and flavors) extending beyond those of conventional cigarettes, suggest that new, specific e-cigarette use measures must be developed. The current study provides timely information on adult e-cigarette use behavior, which is a crucial step in measuring this new phenomenon and assessing the risks associated with using e-cigarette products.

The researcher adapted the measuring instruments for every latent construct from the literature and customized the items to suit this particular study. The study sent the revised questionnaire to 262 respondents in order to gather the pilot study data and able to get 163 filled ones as final data. The set of questionnaires consists of 66 items that assess the 6 constructs. Data is analyzed using SPSS AMOS Version 21.0. The results show that every construct achieved its Bartletts’ Test of Spherici-ty 6.0 with the result of Information Sharing Behavior .000 and .871; Intention .000 and .782; Belief Expectancy .000 and .911; Attitude Influence .000 and .925; Readiness For Change .000 and .959; and Self-Efficacy .000 and .902. The entire item of the construct has exceeded the minimum limit of 0.7 reliability of Alpha Cronbach value to achieve the Internal Reliability. The new integrate model has been proposed due to this finding.

    Near body distance is a key component of action and social interaction. Recent research has shown that peripersonal space (reachability-distance for acting with objects) and interpersonal space (comfort-distance for interacting with people) share common mechanisms and reflect the social valence of stimuli. The social psychological literature has demonstrated that information about morality is crucial because it affects impression formation and the intention to approach-avoid others. Here we explore whether peripersonal/interpersonal spaces are modulated by moral information. Thirty-six participants interacted with male/female virtual confederates described by moral/immoral/neutral sentences. The modulation of body space was measured by reachability-distance and comfort-distance while participants stood still or walked toward virtual confederates. Results showed that distance expanded with immorally described confederates and contracted with morally described confederates. This pattern was present in both spaces, although it was stronger in comfort-distance. Consistent with an embodied cognition approach, the findings suggest that high-level socio-cognitive processes are linked to sensorimotor-spatial processes. Copyright © 2015.

    The main objective of this study is to learn more on the image use and search requirements of radiologists. These requirements will then be taken into account to develop a new search system for images and associated meta data search in the Khresmoi project. Observations of the radiology workflow, case discussions and a literature review were performed to construct a survey form that was given online and in paper form to radiologists. Eye tracking was performed on a radiology viewing station to analyze typical tasks and to complement the survey. In total 34 radiologists answered the survey online or on paper. Image search was mentioned as a frequent and common task, particularly for finding cases of interest for differential diagnosis. Sources of information besides the Internet are books and discussions with colleagues. Search for images is unsuccessful in around 25% of the cases, stopping the search after around 10 minutes. The most common reason for failure is that target images are considered rare. Important additions for search requested in the survey are filtering by pathology and modality, as well as search for visually similar images and cases. Few radiologists are familiar with visual retrieval but they desire the option to upload images for searching similar ones. Image search is common in radiology but few radiologists are fully aware of visual information retrieval. Taking into account the many unsuccessful searches and time spent for this, a good image search could improve the situation and help in clinical practice.

  20. Exploring the relation of harsh parental discipline with child emotional and behavioral problems by using multiple informants. The generation R study.

    Directory of Open Access Journals (Sweden)

    Joreintje D Mackenbach

    Full Text Available Parental harsh disciplining, like corporal punishment, has consistently been associated with adverse mental health outcomes in children. It remains a challenge to accurately assess the consequences of harsh discipline, as researchers and clinicians generally rely on parent report of young children's problem behaviors. If parents rate their parenting styles and their child's behavior this may bias results. The use of child self-report on problem behaviors is not common but may provide extra information about the relation of harsh parental discipline and problem behavior. We examined the independent contribution of young children's self-report above parental report of emotional and behavioral problems in a study of maternal and paternal harsh discipline in a birth cohort. Maternal and paternal harsh discipline predicted both parent reported behavioral and parent reported emotional problems, but only child reported behavioral problems. Associations were not explained by pre-existing behavioral problems at age 3. Importantly, the association with child reported outcomes was independent from parent reported problem behavior. These results suggest that young children's self-reports of behavioral problems provide unique information on the effects of harsh parental discipline. Inclusion of child self-reports can therefore help estimate the effects of harsh parental discipline more accurately.

    Background The levels of coverage of human immunodeficiency virus (HIV) treatment and prevention services needed to change the trajectory of the HIV epidemic among key populations, including gay men and other men who have sex with men (MSM) and sex workers, have consistently been shown to be limited by stigma. Objective The aim of this study was to propose an agenda for the goals and approaches of a sexual behavior stigma surveillance effort for key populations, with a focus on collecting surveillance data from 4 groups: (1) members of key population groups themselves (regardless of HIV status), (2) people living with HIV (PLHIV) who are also members of key populations, (3) members of nonkey populations, and (4) health workers. Methods We discuss strengths and weaknesses of measuring multiple different types of stigma including perceived, anticipated, experienced, perpetrated, internalized, and intersecting stigma as measured among key populations themselves, as well as attitudes or beliefs about key populations as measured among other groups. Results With the increasing recognition of the importance of stigma, consistent and validated stigma metrics for key populations are needed to monitor trends and guide immediate action. Evidence-based stigma interventions may ultimately be the key to overcoming the barriers to coverage and retention in life-saving antiretroviral-based HIV prevention and treatment programs for key populations. Conclusions Moving forward necessitates the integration of validated stigma scales in routine HIV surveillance efforts, as well as HIV epidemiologic and intervention studies focused on key populations, as a means of tracking progress toward a more efficient and impactful HIV response.

    Full Text Available Background: Informant discrepancies have been reported between parent and adolescent measures of depressive disorders and suicidality. We aimed to examine the concordance between adolescent and parent ratings of depressive disorder using both clinical interview and questionnaire measures and assess multi-informant and multi-method approaches to classification.Method: Within the context of assessment of eligibility for a randomized clinical trial, 50 parent–adolescent pairs (mean age of adolescents = 15.0 years were interviewed separately with a structured diagnostic interview for depression, the KID-SCID. Adolescent self-report and parent-report versions of the Strengths and Difficulties Questionnaire, the Short Mood and Feelings Questionnaire and the Depressive Experiences Questionnaire were also administered. We examined the diagnostic concordance rates of the parent vs. adolescent structured interview methods and the prediction of adolescent diagnosis via questionnaire methods.Results: Parent proxy reporting of adolescent depression and suicidal thoughts and behavior is not strongly concordant with adolescent report. Adolescent self-reported symptoms on depression scales provide a more accurate report of diagnosable adolescent depression than parent proxy reports of adolescent depressive symptoms. Adolescent self-report measures can be combined to improve the accuracy of classification. Parents tend to over report their adolescent’s depressive symptoms while under reporting their suicidal thoughts and behavior.Conclusion: Parent proxy report is clearly less reliable than the adolescent’s own report of their symptoms and subjective experiences, and could be considered inaccurate for research purposes. While parent report would still be sought clinically where an adolescent refuses to provide information, our findings suggest that parent reporting of adolescent suicidality should be interpreted with caution.

    This study investigated the associations between parent-child connectedness and sexual behaviors among adolescents living in informal settlements in Nairobi, Kenya, a vulnerable group with respect to reproductive health outcomes. The study was based on data from the Transition to Adulthood project, a study designed to follow adolescents aged 12-22 for 3 years in the informal settlements of Korogocho and Viwandani. Direct face-to-face questions were asked to adolescents about parenting variables and sexual behaviors. This study used a subsample of 689 sexually experienced 12-22-years-olds at Wave 2. Bivariate analysis compared gender differences for three outcomes-sexual activity in the 12 months prior to the survey and, among those who had had sex in this period, multiple sexual partners and condom use at last sex. Multivariate logistic regressions were used to identify associations between these outcomes and the quality of parent-child connectedness. About 60% of adolescent females and males were sexually active in the 12 months prior to the survey. The multivariate results showed a strong association between the quality of parent-child connectedness and condom use among adolescent males. Living with related or unrelated guardians (versus living with biological parents) was also associated with higher odds of multiple sexual partners and lower odds of condom use at last sex among adolescent females and with higher odds of sexual activity among adolescent males. Sexual and reproductive health programs targeting adolescents living in Nairobi informal settlements would benefit from attention to assisting parents to improve their ability to play the connectedness role.

Our studies, grounded in physical theory of continuous percolation and biased random walks, allow us to identify a variety of percolation transitions, which are understood as providing potentially unlimited movement through a space in a specified direction. We discover an unexpected phenomenon of self-organization of gliders in clusters, which resembles the flock organization of birds. This self-organization is intriguing, as it occurs thanks to exchange of information only and without any particular rules that could favor the clustering of the gliders (in contrast to the causes well known in literature, like, for example, attractive forces used in the Vicsek-type models or fitness functions used in evolutionary computation).

    Consumer health informatics (CHI) such as web-based applications may provide the platform for enabling the over 15 million family caregivers of patients with Alzheimer's Disease or related dementias the information they need when they need it to support behavioral symptom management. However, for CHI to be successful, it is necessary that it be designed to meet the specific information needs of family caregivers in the context in which caregiving occurs. A sociotechnical systems approach to CHI design can help to understand the contextual complexities of family caregiving and account for those complexities in the design of CHI for family caregivers. This study used a sociotechnical systems approach to identify barriers to meeting caregivers' information needs related to the management of dementia-related behavioral symptoms, and to derive design implications that overcome barriers for caregiver-focused web-based platforms. We have subsequently used these design implications to inform the development of a web-based platform, WeCareAdvisor,TM which provides caregivers with information and an algorithm by which to identify and manage behavioral symptoms for which they seek management strategies. We conducted 4 focus groups with family caregivers (N=26) in a Midwestern state. Qualitative content analysis of the data was guided by a sociotechnical systems framework. We identified nine categories of barriers that family caregivers confront in obtaining needed information about behavioral symptom management from which we extrapolated design implications for a web-based platform. Based on interactions within the sociotechnical system, three critical information needs were identified: 1) timely access to information, 2) access to information that is tailored or specific to caregiver's needs and contexts, and 3) usable information that can directly inform how caregivers' manage behaviors. The sociotechnical system framework is a useful approach for identifying information

    Full Text Available Introduction: Learning styles influence the methods and ways of obtaining information and lead to the variety of information seeking behaviors from the searchers. This study aimed to investigate the relationship between learning styles and information seeking behavior in master degree students of medical science in Shahid Sadoughi University of Medical Sciences in Yazd. Methods: This study was a cross-sectional analytic study. The population of the study was 601 master degree students of Shahid Sadoughi University of Medical Sciences in Yazd in 2013-2015. They were all freshmen. The sample size of 234 students was determined using Cochran formula. Data were collected by two questionnaires (Kolb questionnaire and researcher-made seeking behavior questionnaire. The validity of questionnaires was confirmed by a panel of experts and their reliability was confirmed by Cronbach`s alpha. Data analysis was done by inferential statistics and statistical software SPSS (version 18. Measuring the significant relationship between learning styles and information seeking behavior was done with Pierson correlation coefficient. The significant difference between learning styles and information seeking behavior in terms of gender and faculty was examined by Fisher`s test. Results: Learning styles had effect on information seeking behavior; also correlation coefficients between the learning styles and information seeking behavior had significant difference, but there was no difference in terms of faculty. Conclution: Recognition of learning styles and including it into designing of information systems may increase system`s interactivity that it may lead to have better and faster accessibility to information resources.

    The outbreak of severe acute respiratory syndrome (SARS) in 2003 marked the explosion of health information seeking online in China and the increasing emergence of Chinese health websites. There are both benefits and potential hazards of people's online health information seeking. This article intended to test part of Wilson's second model of information behavior, including source characteristics and activating mechanisms, and to identify the relationships among perceived access, perceived expertise credibility, reward assessment, Internet self-efficacy, and online health information-seeking behavior. Data were drawn from face-to-face surveys and an online survey of health information seekers (N = 393) in China. The results showed that source characteristics predicted activating mechanisms, which in turn predicted online health information-seeking behavior. Activating mechanisms, that is, reward assessment and Internet self-efficacy, mediated the relationship between source characteristics (i.e., access and credibility) and online health information-seeking behavior. Strategies for improving information access, expertise credibility, and Internet self-efficacy are discussed in order to maximize the benefits of online health information seeking and to minimize the potential harm.

  10. Information, education, and health behaviors: Evidence from the MMR vaccine autism controversy.

    2018-05-02

    In the wake of strong, although later refuted, claims of a link between autism and the measles-mumps-rubella (MMR) vaccine, I examine whether fewer parents immunized or delayed vaccinations for their children and if there was a differential response by mother's education level. Using various controls and a differencing strategy that compares in MMR take-up with other vaccines, I find that the MMR-autism controversy led to a decline in the immediate years and that there were negative spillovers onto other vaccines. I also find evidence that more highly educated mothers responded more strongly to the controversy either by not immunizing their children altogether or, to a lesser degree, delaying vaccination. Moreover, the educational gap was greater in states where there was greater media attention devoted to the controversy. This is consistent with the health allocative efficiency hypothesis whereby part of the education gradient in health outcomes is due to more-educated individuals absorbing and responding to health information more quickly. However, unlike in the United Kingdom, where previous studies find that the gap was eliminated after the link was refuted, the evidence for the United States suggests that the educational gap persisted.

    2013-03-01

    Full Text Available Human behaviour normally depends on the environment of the incident and the time of its occurrence. The behaviour of people depends on many factors and these behaviour traits are an important aspect in the Library and Information Science (LIS field. Hence in this paper an attempt has been made to examine the behaviour traits of LIS students in South India. Out of 400 questionnaires distributed 367 have responded and the response rate is 91.75%. In this survey three aspects comprising student behaviour have been analysed such as Work Environment, Natural Environment, and Social Environment. In the case of Work Environment the respondents were grouped as Workaholic, Impatience, Achievement oriented, Rash nature, and Punctuality. Further, in respect to Natural environment, the respondents are grouped as Complacent, Patience, Easygoing, and Relaxed. Last, the respondents were grouped in the Social Environment as Balancing nature, Magnanimity, Naturalistic, Assertive nature, Dependency, Lucrative, Lonely nature, and Time Based personality. Finally the authors conclude that LIS students need to possess these qualities and behaviours to work in different environments.

    information, with college graduates (OR 2.57, Wald= 3.86, df =1, P=.049) and post graduates (OR 7.105, Wald= 4.278, df=1, P=.04) nearly 2 to 7 times more likely than non-high school graduates to use Web 2.0 for health information. Being younger and possessing more education was associated with greater eHealth literacy among baby boomers and older adults. Females and those highly educated, particularly at the post graduate level, reported greater use of Web 2.0 for health information. More in-depth surveys and interviews among more diverse groups of baby boomers and older adult populations will likely yield a better understanding regarding how current Web-based health information seeking and sharing behaviors influence health-related decision making.

    Online social media offer great potential for research participant recruitment and data collection. We conducted synchronous (real-time) online focus groups (OFGs) through Facebook with the target population of young adult substance users to inform development of Facebook health behavior change interventions. In this paper we report methods and lessons learned for future studies. In the context of two research studies participants were recruited through Facebook and assigned to one of five 90-minute private Facebook OFGs. Study 1 recruited for two OFGs with young adult sexual and/or gender minority (SGM) smokers (range: 9 to 18 participants per group); Study 2 recruited for three groups of young adult smokers who also engage in risky drinking (range: 5 to 11 participants per group). Over a period of 11 (Study 1) and 22 days (Study 2), respectively, we recruited, assessed eligibility, collected baseline data, and assigned a diverse sample of participants from all over the US to Facebook groups. For Study 1, 27 of 35 (77%) participants invited attended the OFGs, and 25 of 32 (78%) for Study 2. Participants in Study 1 contributed an average of 30.9 (SD=8.9) comments with an average word count of 20.1 (SD=21.7) words, and 36.0 (SD=12.3) comments with 11.9 (SD=13.5) words on average in Study 2. Participants generally provided positive feedback on the study procedures. Facebook can be a feasible and efficient medium to conduct synchronous OFGs with young adults. This data collection strategy has the potential to inform health behavior change intervention development.

    The goal of point-of-purchase (POP) nutrition information is to help consumers make informed, healthful choices. Despite limited evaluation, these population-based approaches are being advocated to replace traditional, more expensive, individual behavior-change strategies. Few studies have examined the effect of POP information on buying patterns of college students, a group with high obesity rates and poor eating habits. This quasi-experimental pilot project sought to determine whether the "Eat Smart" POP program affected food-purchasing habits of multiethnic college students shopping at an on-campus convenience store. Baseline sales data of foods in the cereal, soup, cracker, and bread categories were collected for 6 weeks during Fall 2008. After Winter break, a few food items within each of these food categories were labeled as healthful using a "Fuel Your Life" shelf tag, and sales data were then collected for 5 weeks. In each of the four food categories, nontagged foods were available at the identical price as tagged items. Following intervention, there were increased sales of tagged items (measured as a percentage of total sales) in the cereal, soup, and cracker categories, while sales of bread decreased. Although none of these changes were statistically significant, the intervention resulted in a 3.6%±1.6% (P=0.082) increase in the percentage of sales from tagged items. Thus, providing POP nutrition information in a college campus convenience store may promote healthful food choices. A longer study examining the effect of POP on sales of items in other food categories is warranted. Copyright © 2011 American Dietetic Association. Published by Elsevier Inc. All rights reserved.

  17. Maximizing federal Medicaid dollars: nursing home provider tax adoption, 2000-2004.

    Miller, Edward Alan; Wang, Lili

    2009-12-01

    Since Medicaid is jointly financed by the federal and state governments, state officials have sought to offset state expenditures by maximizing federal contributions. One such strategy is to adopt a provider tax, which enables states to collect revenues from providers; those revenues are then used to pay for services rendered to Medicaid recipients, thereby leveraging federal matching dollars without concomitant increases in state expenditures. The number of states adopting a nursing home tax increased from thirteen to thirty-one between 2000 and 2004. This study seeks to identify the factors that spurred the rapid increase in nursing home provider taxes following implementation of the Balanced Budget Act of 1997. Results indicate that states with more powerful nursing home lobbies, lower proportions of private pay nursing home residents, worse fiscal health, weaker fiscal capacity, broader Medicaid eligibility, and nursing home supply restrictions were more likely to adopt. This implies that state officials react rationally to prevailing fiscal and programmatic circumstances when formulating policy under Medicaid and that providers seek relief, in part, from the adverse fiscal consequences of federal policy changes by promoting policy change at the state level.

  1. International wind energy development. World marked update 1999. Forecast 2000-2004

    International Nuclear Information System (INIS)

    2000-03-01

    This is the fifth issue of the annual World Market Update by BTM Consult ApS, covering the year 1999. All figures in the status refer to the end of year 1999. It is the last update from the 20th century, in which wind energy developed during the last two decades to become a very serious part of the world electricity supply. As in previous reports, the past 3 years' development in the wind energy sector is assessed, and the forecast looks 5 years ahead. Wind power is the world's fastest growing energy source, with an average annual growth rate of 40 % over the last five years. Wind energy is a clean and abundant energy source, and it is becomming a preferred source of energy not only due to the environmental benefits, but also because it has become increasingly cost competitive in the world energy markets. One of the most significant figures and trends from this fast growing market during 1999 was that the annual installation of new wind power capacity increased by 51 %, resulting in a cumulative installation by the end of 1999 of 13,932 MW. The growth rates in the wind industry can easily be compared to the growth rates in the IT sector, although the growth differ much from country to country. The high growth rates are still very much influenced by political and economical issues, but the continuously improved technology and thus also the redused cost of energy becomes more and more significant, and there are hardly any arguments left why wind energy should not play a very significant role in the electricity supply. Approximately 81 % of the new capacity of 3,922 were installed in Europe, emphasizing that this region is still the major market place. The US market picked up close to the PTC expiry date (Production Tax Credit) on June 30, 1999. In terms of single markets it was, however, the German market which once again took the lead with installed capacity of 1,568 MW. Germany thereby consolidated the position as the leading wind energy country in the world. Spain also took a major step towards the Spanish renewable energy goals by installing some 930 MW. The installed capacity of 13,932 MW at the end of 1999 will supply approximately 30 TWh (30 billon kWh). The top market leaders during the two last years maintained their positions, and NEG Micon A/S is still at the top in spite of the company's financial crisis in late 1999. It is interesting to see how this company was supported by the shareholders and lenders to overcome the crisis. Vestas Wind Systems holds in direct sales the 2nd position. Along with its joint venture companies, however, Vestas Wind Systems holds some 30 % of the worlds wind energy market. In third position the Spanish company Gamesa S.A holds 12.6 % of the market. Gamesa S. A. is owned to 40 % by Vestas Wind Systems A/S. One newcomer, DeWind GmbH, a German manufacturer appeared for the first time among the top ten suppliers. Two very important signals from the world market were the reinstated PTC in the US market and the fixed rates for the electricity from wind turbines most recently in Germany. The common use of MW wind turbines has been growing since these wind turbines became commercially available about 3 years ago. The increased power output by the wind turbines has been the major factor in cutting the cost of energy produced, and it is interesting to look at the declining cost of the electricity produced by wind turbine generators, as it has been cut by a factor of 3-4 over the past 20 years. The special topic of this year's World Market Update is the future cost reduction in wind generation. Design and optimization of larger components such as blades, gearboxes and generators has been in focus during recent years. Nevertheless, it is impressive to see how the more untraditional concept by Enercon in Germany spreads in the market. Some new companies try to take similar revolutionary steps to avoid the sometimes troublesome gearbox. The wind energy market still to some extent depends on the political arena, on government policies and on different support programs - things which may change and give some fluctuations in the market. The strategy of the manufacturers to overcome such fluctuations is to spread sales geographically. In the revised forecast for the coming five years growth rates of 20 % per year will be seen. An average growth rate of 20 % might be considered conservative, but on top of two years' growth rates of more than 50 % (1998 and 1999), the resulting annual sales at the end of the forecast period amount to more than 9,000 MW per year (year 2004). Beyond year 2004, a more aggressive development in Asia is predicted and in the remaining parts of the world as well. The long awaited off-shore market seems to be somewhat more difficult to get moving, and this has been reflected in the new forecast. (EHS)

    Full Text Available Vegetation net primary productivity (NPP is always used as an indicator of carbon cycling in terrestrial ecosystems at landscape and regional scales. Based on the CASA model, we analyzed the spatiotemporal pattern of growing season NPP from 2000 to 2004 using MODIS/NDVI and its relationship with precipitation. The result shows that the annual NPP in Mongolia has a tendency to slightly decrease from 61.13 in 2000 to 60 gC/m2 /yr in 2004, with an annual mean decrement of -0.259 gC/ m2 /yr. However, annual and inter-annual NPP trends showed spatial and temporal heterogeneity. NPP in forest and grassland has decreased with an average annual decrement of -1.03 (r2=0.262 and -0.49 (r2=0.324, meanwhile NPP in desert steppe and desert has increased with the annual average increment of 0.4327 (r2=0.322 and 0.2401 (r2=0.283, respectively. The correlation coeffi cient showed that mean growing season NPP in grassland and desert steppe were closely correlated with precipitation than forest and desert.

    2006-08-01

    More systematic reviews related to orthodontic topics are published each year, although little has been done to evaluate their search and selection methodologies. Systematic reviews related to orthodontics published between January 1, 2000, and December 31, 2004, were searched for their use of multiple electronic databases and secondary searches. The search and selection methods of identified systematic reviews were evaluated against the Cochrane Handbook's guidelines. Sixteen orthodontic systematic reviews were identified in this period. The percentage of reviews documenting and using each criterion of article searching has changed over the last 5 years, with no recognizable directional trend. On average, most systematic reviews documented their electronic search terms (88%) and inclusion-exclusion criteria (100%), and used secondary searching (75%). Many still failed to search more than MEDLINE (56%), failed to document the database names and search dates (37%), failed to document the search strategy (62%), did not use several reviewers for selecting studies (75%), and did not include all languages (81%). The methodology of systematic reviews in orthodontics is still limited, with key methodological components frequently absent or not appropriately described.

  6. Review of atmospheric metallic elements in Asia during 2000-2004

    Fang, Guor-Cheng; Wu, Yuh-Shen; Huang, Shih-Han; Rau, Jui-Yeh

    Metallic element transfer through the atmosphere is a significant part of the biogeochemical cycle of these elements. Natural and anthropogenic were two processes which can increase heavy metal concentrations in the atmosphere. Atmospheric particulates, especially secondary anthropogenic fine particles (PM 2.5), have been influence human health. Generally speaking, the total daily mortality increases by approximately 1% for every 10 μg m -3 increase in PM 10 concentration (Lippmann, 1998). This is why the PM 10 and PM 2.5 measurements are included in the US ambient air quality standards (US-EPA, 1987 for PM 10; 1996 for PM 2.5) (Querol et al., 2001). In recent years, since the great efforts made by Taiwan government towards the reduction of O 3 and PM 10 concentrations by controlling the emission rates of local pollutants sources, the frequency of exceeded PSI has gradually decrease the value of 4.9% in 1999 (Taiwan EPA, 2000). Urban populations are exposed to metals in suspended particles and these are often well above natural background levels owing to anthropogenic processes (Espinosa et al., 2002). This results in elevated metal concentrations that can pose an important risk to human health. Understanding emissions from traffic includes identification of the sources, which is also crucial for designing control measures. Road traffic involves numerous potential sources of metals, combustion products from fuel and oil, wear products from tires, brake linings, bearings, coach and road construction materials, and re-suspension of soil and road dust. The different sample collection devices, pretreatment and analysis methods were discussed in this study. The purpose of this study arranges the atmospheric metallic elements investigations in Asia regions. The data obtained here can also help to understand the sources, concentration, phase distribution and health impact of atmospheric metallic elements in Asian countries.

  8. Stakeholder involvement and decommissioning. Some lessons derived from papers presented at WPDD (2000 - 2004)

    Pescatore, Claudio

    2006-01-01

    Decommissioning and dismantling (D and D) are the last elements of the life cycle of both nuclear and non-nuclear facilities. The problems of this phase are partly the same and partly different from those of the preceding phases (planning, construction and operation). Public concerns about safety, for instance, are present in every phase. In the course of construction and operation important challenges include meeting public expectations of a higher quality of life, accommodation of an increasing population, mitigation of construction nuisances and assurance of the safe operation of the facility. In the decommissioning and dismantling phase public concerns include decrease in employment, the reduction of revenues for the municipality, the future use of the affected land, and other negative social impacts (e.g. emigration of part of the skilled population) [d'Abadal, Castellnou]. This phase too is characterised - as earlier phases - by the heterogeneity of stakeholder interests and values, and the difficulties to achieve consensus or compromise. The difficulties arise in connection with the harmonisation of energy production, environmental protection and sustainable socio-economic development considerations. Issues of interaction between local and regional decisions are also characteristic. From the point of view of conflict management the building of trust amongst stakeholders is very important in the decommissioning and dismantling phase. Consequently, social lessons learned from the siting and development of nuclear facilities are widely applicable in the field of D and D. This paper summarises some lessons learned from papers on stakeholder involvement presented at WPDD meetings mainly between 2000 and 2004. In conclusion, community/stakeholder participation and economic development involve the identification of all relevant stakeholders and the community needs. There must be an early discussion of plans with all stakeholders. A continuous dialogue with the communities/stakeholders is vital and it is also important that the communication not only contains technical matters but also deals with feelings and 'soft values'. The dialogue process must be completely transparent and the roles of each actor must be clear. Attitudes and behaviour of each stakeholder plays an important role in the outcome of the process. Successful community/stakeholder involvement is hence a result of a carefully crafted set of coordinated activities over the long-term. (author)

The objectives of the colloid project are to: (i) study the role of bentonite as a colloid source, (ii) verify the background colloid concentration at Aespoe HRL and, (iii) investigate the potential for colloid formation/transport in natural groundwater concentrations. The experimental concepts for the colloid project are: laboratory experiments with bentonite, background field measurements of natural colloids, borehole specific bentonite colloid stability experiments and a fracture specific transport experiment. The activities concerning the laboratory experiments and background field measurements are described in this work; the other activities are ongoing or planned. The following conclusions were made: The bentonite colloid stability is strongly dependent on the groundwater ionic strength. Natural colloids are organic degradation products such as humic and fulvic acids, inorganic colloids (clay, calcite, iron hydroxide) and microbes. Microbes form few but large particles and their concentration increase with increasing organic carbon concentrations. The small organic colloids are present in very low concentrations in deep granitic groundwater. The concentrations can be rather high in shallow waters. The colloid concentration decreases with depth and salinity, since colloids are less stable in saline waters. The colloid content at Aespoe is less than 300 ppb. The colloid content at repository level is less than 50 ppb. The groundwater variability obtained in the boreholes reflects well the natural groundwater variability along the whole HRL tunnel.

    In this first institutional plan prepared by Bechtel BWXT Idaho, LLC, for the Idaho National Engineering and Environmental Laboratory, the INEEL will focus its efforts on three strategic thrusts: (1) Environmental Management stewardship for DOE-EM, (2) Nuclear reactor technology for DOE-Nuclear Energy (NE), and (3) Energy R and D, demonstration, and deployment (initial focus on biofuels and chemicals from biomass). The first strategic thrust focuses on meeting DOE-EMs environmental cleanup and long-term stewardship needs in a manner that is safe, cost-effective, science-based, and approved by key stakeholders. The science base at the INEEL will be further used to address a grand challenge for the INEEL and the DOE complex--the development of a fundamental scientific understanding of the migration of subsurface contaminants. The second strategic thrust is directed at DOE-NEs needs for safe, economical, waste-minimized, and proliferation-resistant nuclear technologies. As NE lead laboratories, the INEEL and ANL will pursue specific priorities. The third strategic thrust focuses on DOE's needs for clean, efficient, and renewable energy technology. As an initial effort, the INEEL will enhance its capability in biofuels, bioprocessing, and biochemicals. The content of this institutional plan is designed to meet basic DOE requirements for content and structure and reflect the key INEEL strategic thrusts. Updates to this institutional plan will offer additional content and resource refinements.

    Full Text Available The E-rate program has provided tremendous benefits to libraries, allowing many libraries and library systems to acquire technological equipment and services that would otherwise be too expensive, increasing the availability of public Internet access through libraries. This article analyzes the data related to the E-rate program and the discounts that it has provided to libraries and library systems between 2000 and 2004. By examining the E-rate data in a longitudinal manner, this article explores the trends in the application for and the provision of E-rate discounts to libraries and library consortia at national and state levels. The data suggest that, despite a number of controversies over the years, the program has provided a significant level of support for libraries and library consortia.

  13. Energy consumption behavior in the commercial sector: An ethnographic analysis of utility bill information and customer comprehension in the workplace

    Payne, Christopher Todd

    The commercial and industrial sectors of the United States compose roughly one-third of total United States energy consumption. Many studies have suggested that significant cost-effective energy savings opportunities exist in this sector, but there is a gap between predictions of potential and actual investment in energy-efficient technologies. Very few studies have been conducted to examine the decision-making environment of the business sector. In particular, there is essentially no information about how small-business decision-makers make choices about energy consumption. My research is intended to begin the process of understanding this important arena of energy consumption behavior. Using semi-structured interview techniques, I interviewed forty-four businesses in ten states. The focus of the interviews was the business decision-maker's handling and use of the utility bill---the main (often sole) piece of information that links energy consumption to cost. Through the interviews, I collected information about how utility bills are understood and misunderstood, what components of the bill are seen as useful or confusing, and how energy consumption was seen in the context of larger business decision-making. In addition, I collected data on two forms of energy consumption feedback: historic consumption feedback, in which informants compared their current energy use to patterns of their own energy consumption over time; and group comparison consumption feedback, in which informants compared their energy consumption to the consumption of a group of similar energy consumers. Finally, I collected data on sources of information to which decision-makers turned when they wanted to seek more information about energy consumption alternatives. Overall, my findings suggest that the current utility bill format is often misunderstood. In many cases, particularly in the small-business and medium-size-business categories, the link between energy consumption and energy cost is

    Full Text Available This paper aims to determine the influence of contextual factors on information seeking behavior. This survey investigates search tactics used and users’ perceptions of the search results on the Web by postgraduate students at Kerman University of Medical Sciences. This study was conducted through a mixed method. Thirty postgraduate students voluntarily participated. The study was carried out in the first semester of the academic year 2012-2013. The data was gathered using two questionnaires and log files recorded with Camtasia Studio software. The findings indicated more than half of the participants (53.3 percent used Google, short queries were more used than long queries, advanced search options were used rarely (23 percent, and the participants view few search result pages. According to the results, the contextual factors significantly influenced the search time, search tactics (including querying and navigating and users’ perceptions of the search results (including ease of use, usefulness, satisfaction and relevance judgment. Navigating tactic was primarily used by the participants. Among different aspects of users’ perceptions of the search results, ease of use and relevance judgments were significantly different based on the contextual factors, whereas scanning, extracting, and confidence were less affected by the contextual factors. The findings suggest practical implications for information retrieval systems designers that can design of systems with better user interface in order to meet the needs of users with different knowledge and skills, in this way it leads in promotion of search process and improvement of search results quality.

    This document is one in a series of topical reports compiled by the Pacific Northwest National Laboratory to summarize technical information on selected topics important to the performance of a probabilistic seismic hazard analysis (PSHA) of the Hanford Site. The purpose of this report is to summarize available data and analyses relevant to the Yakima Fold Belt (YFB) that may bear on the question of whether or not the YFB behaves as a single seismotectonic province in which activity along one fold structure is representative of behavior along all other fold structures. This topic has met with a fairly high level of contention in the expert community and has the potential to result in significant impacts on an evaluation of seismic hazard at the Hanford Site. This report defines the relevant alternative conceptual models relevant to this technical issue and the arguments and data that support those models. It provides a brief description of the technical issue and principal uncertainties; a general overview on the nature of the technical issue, along with alternative conceptual models, supporting arguments and information, and uncertainties; and finally, it suggests some possible approaches for reducing uncertainties regarding this issue.

    Given the unpaid nature of the work, informal caregiving can create a financial burden for caregivers. Little has been done to identify specific predictors of experiencing financial burden. This study investigated demographic and health factors comparing caregivers who reported having or not having financial burden. Data are derived from adult caregivers (N = 3,317) as part of the 2007 Behavioral Risk Factor Surveillance System in Hawaii, Kansas, and Washington. The adjusted odds ratios for reporting a financial burden were estimated for demographic and other risk factors. Caregivers who reported a financial burden were younger, had lower incomes, were more likely to be current smokers, have had a stroke, and rate their health as fair or poor compared to caregivers who did not report a financial burden. Caregivers who were younger (ages 18-34), resided with care recipients, spent 20-39 hours per week providing care, and reported having a disability were at a statistically significantly higher odds of reporting a financial burden. Given the current economic difficulties faced by many Americans, further insights into the perceived financial burdens experienced by informal caregivers as well as linkages to policy and programs designed to support caregivers are critical for public health professionals to address the expanding needs in states and communities.

    The characteristics of learning processes and long-term memory (LTM) were studied in rhesus macaques discriminating visual stimuli (geometrical figures of different shapes, sizes, and orientations, and with different spatial relationships between image components). Trained monkeys were tested for the ability to perform invariant recognition after stimulus transformation, i.e., changes in size, shape, number of objects, and spatial relationships. Analysis of behavioral characteristics (correct solutions, refusals to decide, motor response times) revealed differences associated with the type of visual information. When monkeys discriminated between black and white geometrical figures of different shapes and orientations, as well as black-and-white figures with different shapes or orientations, the learning time was short and transformation of the stimuli had no effect on correct solutions: there was complete transfer of learning. When monkeys discriminated figures of different sizes or complex images with different spatial relationships, the learning time was significantly greater. Changes in the size and shape of figures led to significant reductions in correct solutions and significant increases in refusals to solve the task and in motor reaction times. Invariance of discrimination in this case appeared after additional training. The results obtained here showed that in conditioned reflex learning, the sensory processing of stimuli has the result that discriminatory features are formed in LTM, i.e., cognitive structures (functional neurophysiological mechanisms), these supporting the classification of visual images. The temporal conditioned link of the executive reaction is established with these. Their formation is determined by the type of sensory information and the existence in LTM of separate subsystems for spatial and non-spatial information.

    The objective of this study was to investigate appraisal of means (ie, self-efficacy, outcome expectancy, and affect) in predicting patients' goal-directed behaviors of direct-to-consumer advertising (DTCA)-prompted drug-information search from physicians and the internet. One thousand patients were randomly selected from a nationwide sample frame of 3000 osteoarthritis patients. A self-administered survey assessed exposure to DTCA, drug-information search as goal, self-efficacy, outcome expectancy, affect, and osteoarthritis pain. After 6 weeks, another survey measured the behavior of drug-information search for respondents to the first survey. Study subjects were those who were exposed to DTCA in the previous month, and who set drug-information search as their goal. For each information source, a multiple regression analysis was conducted in which drug-information search was the dependent variable, and self-efficacy, outcome expectancy, affect, and osteoarthritis pain were the independent variables. Among 454 patients who were exposed to DTCA, 174 patients set drug-information search as their goal and were the study subjects. The regression for physicians was not statistically significant. The regression for the internet was significant, accounting for 15% of behavior variance. Self-efficacy was a strong predictor of goal-directed drug-information search from the internet. Appraisal of means was useful to predict the goal-directed behavior of DTCA-prompted drug-information search from the internet. For patients who set drug-information search as a goal, actions to promote drug-information search from the internet need to focus on self-efficacy.

    The goal of this study was to examine whether moral affect, moral cognition, negative emotionality, and attribution biases independently predicted adolescents' prosocial and aggressive behavior in adolescence. A total of 148 adolescents completed self-report measures of prosocial and aggressive behavior, moral affect, moral cognition, negative emotionality, and attribution biases. Although in general all 3 factors (emotional, moral, and social cognitive) were correlated with adolescent social behavior, the most consistent independent predictors of adolescent social behavior were moral affect and cognition. These findings have important implications for intervention and suggest that programs that promote adolescent perspective taking, moral reasoning, and moral affect are needed to reduce aggressive behavior and promote prosocial behavior.

    Nutrition interventions targeting the first 1000 days show promise to improve nutritional status, but they require effective implementation. Formative research is thus invaluable for developing such interventions, but there have been few detailed studies that describe this phase of work within the Scaling Up Nutrition (SUN) movement. To inform a stunting prevention intervention in Cabo Delgado, Mozambique, by describing the sociocultural landscape and elucidating characteristics related to young child food, illness, and health. This formative research utilized a rapid assessment procedures (RAP) approach with 3 iterative phases that explored local perceptions and behaviors around food and illness among the Macua, Mwani, and Maconde ethnic groups. Ethnographic methods, including in-depth interviews, direct observations, free lists, and pile sorts, were used to collect data from community leaders, caregivers, and children 6 to 23 months. Data were analyzed drawing from grounded theory and cultural domain analysis. Geographic differences drive sociocultural characteristics amid 3 ethnic groups that allow for segmentation of the population into 2 distinct audiences for behavior change communications. These 2 communities have similar classification systems for children's foods but different adult dietary patterns. Small-quantity lipid-based nutrient supplement did not fall into the existing food classification systems of either community, and participants preferred its promotion through community leader channels. Community members in both groups have little recognition of and perceived severity toward nutrition-related illnesses. Within Cabo Delgado, the cultural heterogeneity yields substantial differences related to food, illness, and health that are necessary to consider for developing an effective nutrition intervention. © The Author(s) 2015.

  1. Children's behavioral health needs and satisfaction and commitment of foster and adoptive parents: Do trauma-informed services make a difference?

    Caring for children in foster or adoptive care with behavioral health needs can severely stress parents, contributing to adverse outcomes for children and families. Trauma-informed services from the child welfare and mental health sectors may help prevent poor outcomes by helping children and parents identify and understand trauma and its impact on children's behavioral health and receive effective treatment. To help understand the role of trauma-informed services for the child welfare population, we examined whether trauma-informed child welfare and mental health services moderated the relationship between children's behavioral health needs and parent satisfaction and commitment. The researchers analyzed data from a cross-sectional statewide survey of foster and adoptive parents (n = 512 respondents, 42% of 1,206 contacted) from one state. Foster (but not adoptive) parent ratings of trauma-informed mental health services significantly moderated the relationship between children's behavioral health needs and foster and adoptive parent satisfaction and commitment. As ratings of trauma-informed mental health services increased, the association between child behavioral health needs and parent satisfaction and commitment became nonsignificant, suggesting a buffering effect. Trauma-informed child welfare services did not moderate the relationship for foster or adoptive parents. Leaders and policymakers are urged to promote trauma-informed mental health services for children involved with child welfare to potentially buffer foster parents against lower parenting satisfaction and commitment. More research is needed to replicate and expand on these findings and to examine the effectiveness of trauma-informed services on other relevant child and family outcomes.

    Trait inference in person perception is based on observers' implicit assumptions about the relations between trait adjectives (e.g., fair) and the either consistent or inconsistent behaviors (e.g., having double standards) that an actor can manifest. This article presents new empirical data and theoretical interpretations on people' behavioral expectations, that is, people's perceived trait-behavior relations along the morality (versus competence) dimension. We specifically address the issue of the moderate levels of both traits and behaviors almost neglected by prior research by using a measure of the perceived general frequency of behaviors. A preliminary study identifies a set of competence- and morality-related traits and a subset of traits balanced for valence. Studies 1-2 show that moral target persons are associated with greater behavioral flexibility than immoral ones where abstract categories of behaviors are concerned. For example, participants judge it more likely that a fair person would behave unfairly than an unfair person would behave fairly. Study 3 replicates the results of the first 2 studies using concrete categories of behaviors (e.g., telling the truth/omitting some information). Study 4 shows that the positive asymmetry in morality-related trait-behavior relations holds for both North-American and European (i.e., Italian) individuals. A small-scale meta-analysis confirms the existence of a positive asymmetry in trait-behavior relations along both morality and competence dimensions for moderate levels of both traits and behaviors. We discuss these findings in relation to prior models and results on trait-behavior relations and we advance a motivational explanation based on self-protection.

    Health information obtained from the Internet has an impact on patient health care outcomes. There is a growing concern over the quality of online health information sources used by diabetic patients because little is known about their health information-seeking behavior and the impact this behavior has on their diabetes-related self-care, in particular in the Middle East setting. The aim of this study was to determine the online health-related information-seeking behavior among adult type 2 diabetic patients in the Middle East and the impact of their online health-related information-seeking behavior on their self-care activities. A cross-sectional survey was conducted on 344 patients with type 2 diabetes attending inpatient and outpatient primary health care clinics at 2 teaching hospitals in Riyadh, Saudi Arabia. The main outcome measures included the ability of patients to access the Internet, their ability to use the Internet to search for health-related information, and their responses to Internet searches in relation to their self-care activities. Further analysis of differences based on age, gender, sociodemographic, and diabetes-related self-care activities among online health-related information seekers and nononline health-related information seekers was conducted. Among the 344 patients, 74.1% (255/344) were male with a mean age of 53.5 (SD 13.8) years. Only 39.0% (134/344) were Internet users; 71.6% (96/134) of them used the Internet for seeking health-related information. Most participants reported that their primary source of health-related information was their physician (216/344, 62.8%) followed by television (155/344, 45.1%), family (113/344, 32.8%), newspapers (100/344, 29.1%), and the Internet (96/344, 27.9%). Primary topics participants searched for were therapeutic diet for diabetes (55/96, 57%) and symptoms of diabetes (52/96, 54%) followed by diabetes treatment (50/96, 52%).

    Understanding health information-seeking behaviors and barriers to care and access among pregnant women can potentially moderate the consistent negative associations between poverty, low levels of literacy, and negative maternal and child health outcomes in India. Our seminal study explores health information needs, health information-seeking behaviors, and perceived information support of low-income pregnant women in rural India. Using the Wilson Model of health information-seeking framework, we designed a culturally tailored guided interview to assess information-seeking behaviors and barriers to information seeking among pregnant women. We used a local informant and health care worker to recruit 14 expectant women for two focus group interviews lasting 45 minutes to an hour each. Thirteen other related individuals including husbands, mothers, mothers-in-law, and health care providers were also recruited by hospital counselors for in-depth interviews regarding their pregnant wives/daughters and daughters-in-law. Interviews were transcribed and analyzed by coding the data into thematic categories. The data were coded manually and emerging themes included pregnancy-related knowledge and misconceptions and personal, societal, and structural barriers, as well as risk perceptions and self-efficacy. Lack of access to health care and pregnancy-related health information led participants to rely heavily on information and misconceptions about pregnancy gleaned from elder women, friends, and mothers-in-law and husbands. Doctors and para-medical staff were only consulted during complications. All women faced personal, societal, and structural level barriers, including feelings of shame and embarrassment, fear of repercussion for discussing their pregnancies with their doctors, and inadequate time with their doctors. Lack of access and adequate health care information were of primary concern to pregnant women and their families. Our study can help inform policies and multi

    With disproportionately higher rates of HIV/AIDS among youth and increasing access to antiretroviral therapy (ART) in Thailand, there is a growing urgency in understanding the challenges to medication adherence confronting this population and in developing theory-based interventions to address these challenges. One potentially relevant model, the information-motivation-behavioral skills (IMB) model of adherence, was developed in Western settings characterized by a more individualistic culture in contrast to the more collectivistic culture of Thailand. We explored the application and adaptability of IMB on ART adherence among HIV-positive Thai youth through the analysis of qualitative data from a pilot motivational interviewing study. Twenty-two interview sessions from 10 HIV-positive Thai youth (17-24 years) were analyzed; 6 youth were on ART. Data support the utility of IMB as a potential framework for understanding ART adherence in this population. However, data indicate a consideration to expand the motivation construct of IMB to incorporate youths' perceived familial and social responsibilities and the need to adhere to medications for short- and long-term well-being of self, family, and society in a context of Buddhist values. These modifications to IMB could be relevant in other cultural settings with more collectivistic worldviews.

    In designing digital interventions for healthcare, it is important to understand not just whether interventions work but also how and for whom-including whether individual intervention components have different effects, whether a certain usage threshold is required to change behavior in each intervention and whether usage differs across population subgroups. We investigated these questions using data from a large trial of the digital PRimary care trial of a website based Infection control intervention to Modify Influenza-like illness and respiratory tract infection Transmission) (PRIMIT) intervention, which aimed to reduce respiratory tract infections (RTIs) by increasing hand hygiene behavior. Baseline and follow-up questionnaires measured behaviors, intentions and attitudes in hand hygiene. In conjunction with objective measures of usage of the four PRIMIT sessions, we analysed these observational data to examine mechanisms of behavior change in 8993 intervention users. We found that the PRIMIT intervention changed behavior, intentions and attitudes, and this change was associated with reduced RTIs. The largest hand hygiene change occurred after the first session, with incrementally smaller changes after each subsequent session, suggesting that engagement with the core behavior change techniques included in the first session was necessary and sufficient for behavior change. The intervention was equally effective for men and women, older and younger people and was particularly effective for those with lower levels of education. Our well-powered analysis has implications for intervention development. We were able to determine a 'minimum threshold' of intervention engagement that is required for hand hygiene change, and we discuss the potential implications this (and other analyses of this type) may have for further intervention development. We also discuss the application of similar analyses to other interventions.

    Socially disruptive behavior during peer interactions in early childhood is detrimental to children’s social, emotional, and academic development. Few studies have investigated the developmental underpinnings of children’s socially disruptive behavior using genetically-sensitive research designs that allow examination of parent-on-child and child-on-parent (evocative genotype-environment correlation) effects when examining family process and child outcome associations. Using an adoption-at-birth design, the present study controlled for passive genotype-environment correlation and directly examined evocative genotype-environment correlation (rGE) while examining the associations between family processes and children’s peer behavior. Specifically, the present study examined the evocative effect of genetic influences underlying toddler low social motivation on mother-child and father-child hostility, and the subsequent influence of parent hostility on disruptive peer behavior during the preschool period. Participants were 316 linked triads of birth mothers, adoptive parents, and adopted children. Path analysis showed that birth mother low behavioral motivation predicted toddler low social motivation, which predicted both adoptive mother-child and father-child hostility, suggesting the presence of an evocative genotype-environment association. In addition, both mother-child and father-child hostility predicted children’s later disruptive peer behavior. Results highlight the importance of considering genetically-influenced child attributes on parental hostility that in turn link to later child social behavior. Implications for intervention programs focusing on early family processes and the precursors of disrupted child social development are discussed. PMID:24364829

    Full Text Available 無The purpose of this research was trying to understand the information seeking behavior derived from the studying and teaching informationo needs of those agricultural researchers. Concluded from the phenomena of their information seeking behavior and the factors behind, it might offer the libraries and other agricultural information service center as a reference to improve their service.   The subjects involved in this research were the agricultural teachers at National Chiayi Institute of Agriculture. In this research, there were five questions raised. By way of clarify these five questions as followed, it is possible to reach the purpose of this research.   1.What is the current studying and teaching conditions of the teachers? 2.What kind of studying and teaching situations will make the teachers have information needs? 3.What are the critical ways for the teachers to get needed literature? 4.How do the teachers use formal information channels? 5.How do the teachers use informal information channels? The data supporting this research were gathered through the methods of interview and questionnaire survey. The findings were: on teaching, the major situation having information needs for the teachers occurred when they were compiling texbook or handouts; on studying, it also happened when they wanted to complete the studies subsidized by the National Science Council, Council of Agriculture or Department of Agriculture: Taiwan Provincial Government. The commonest way for the teachers to obtain information resources

    Although information-motivation-behavioral skills (IMB) adherence model has been successfully used in many illness domains and with other populations, it has not been used in understanding mammogram screening among low-income African-American women. Thus, a qualitative examination is needed to theoretically and collectively understand the barriers to screening, given the disparities in breast cancer mortality rates among this population. Semi-structured telephone interviews were conducted with 28 low-income uninsured and underinsured African-American women, 40 to 70 years, who had not had a mammogram within the past 12 months. Women were recruited from 21 hair and nail salons and Laundromats within the five North St. Louis city zip codes with the highest breast cancer mortality rates. Transcripts were analyzed and rooted in grounded theory. This study found that the individual relevancy of information, behavioral skills-both procedural and systematic-and motivation seemed to affect screening adherence; (the results suggest the importance of reordering traditional IMB components into the following sequential order: information, behavioral skills, and motivation (IBM)). Future analyses should include a larger, more representative sample of unscreened women, in which quantitative statistical analyses could be conducted to assist in strengthening assertions about information, behavioral skills, and motivational aspects and their relationship to screening.

    This study examines a behavioral tripartite model developed in the field of addiction, and applies it here to understanding general and impulsive information technology use. It suggests that technology use is driven by two information-processing brain systems: reflective and impulsive, and that their effects on use are modulated by interoceptive awareness processes. The resultant reflective-impulsive-interoceptive awareness model is tested in two behavioral studies. Both studies employ SEM techniques to time-lagged self-report data from n 1 = 300 and n 2 = 369 social networking site users. Study 1 demonstrated that temptations augment the effect of habit on technology use, and reduce the effect of satisfaction on use. Study 2 showed that temptations strengthen the effect of habit on impulsive technology use, and weaken the effect of behavioral expectations on impulsive technology use. Hence, the results consistently support the notion that information technology users' behaviors are influenced by reflective and impulsive information processing systems; and that the equilibrium of these systems is determined, at least in part, by one's temptations. These results can serve as a basis for understanding the etiology of modern day addictions.

    Full Text Available As it is seen that behavioral factors are more effective than expected and predictable factors in the world of finance; to determine the behavioral factors, functioning mechanisms and evaluation of results about the factors has been entailed in one sense. In this study it is aimed to reveal the behavioral finance dimension of investment decisions and a behavioral finance scale has been tried to be created by the factor analysis study applied over the data obtained by field study performed on the ICT sector employees. The distinctive aspect of the study compared to the previous ones is that it has the features of the first known study in the literature made for determining the behavioral finance trends of investors employed in the ICT sector. The survey study made to determine the participants' behavioral biases in finance has been prepared in two propositions defining 42 biases of which 21 are defined in the literature. In the study, firstly concepts of investment, decision making and behavioral biases in finance has been outlined and then detailed with a field study. With the analyses, it is achieved that all 21 behavioral biases affected the investors’ investment behaviors middle or higher level. As a result of the factor analysis 12 factors has been detected. In terms of the findings obtained, this study is expected to contribute to the literature and to the subsequent studies.
