Selected AbstractsDoes Participation Affect Deception Success?HUMAN COMMUNICATION RESEARCH, Issue 4 2001A Test of the Interactivity Principle Communication episodes may range from highly interactive to noninteractive. The principle of interactivity refers to the constellation of structural and experiential features associated with interactivity that systematically affect communication processes and outcomes. One such feature is degree of participation. In deceptive interchanges, senders may engage in dialogic (high participation, two-way) or monologic (low participation, one-way) communication. According to the principle of interactivity, dialogue should advantage deceivers relative to monologue due to increased mutuality between sender and receiver and greater opportunities for deceivers to improve their performance over time. An experiment in which friends or strangers alternated between deceiving and telling the truth to a partner under dialogue or monologue conditions tested this principle. All hypotheses received some support. Relative to monologue, dialogue created more mutuality among strangers. Dialogue also enabled deceivers to better manage their informational content, speech fluency, nonverbal demeanor, and image, resulting in less accurate deception detection by partners. These results support the interactivity principle and interpersonal deception theory, from which the principle emanated. [source] Migrants and Changing Urban Periphery: Social Relations, Cultural Diversity and the Public Space in Istanbul's New NeighbourhoodsINTERNATIONAL MIGRATION, Issue 3 2008Sencer Ayata This study examines the dynamics of socio-cultural change in a peripheral neighbourhood in Istanbul, an "edge city" that is ethnically mixed, culturally heterogeneous, socially differentiated and spatially multi-functional. One major focus in the study is the changing nature of social relations in traditional groups. Though kinship, hem,eri (place of origin) and neighbourhood solidarity is still crucial in the lives of the migrants, participation in these groups becomes more voluntary and the ties among members less obligatory. Secondly, the ethnic and religious groupings in the neighbourhood are not always exclusive, authoritarian and patriarchal communities. What generally appears as rigid communitarian fragmentation is often one of cultural diversity for the residents of the locality. The associational pluralism that exists in the neighbourhood enables people to claim multiple ethnic, religious, political and cultural identities. Thirdly, though they compare unfavourably with their middle class counterparts in the city, the new neighbourhoods provide greater opportunities and more public space for interaction among the members of the locality than for instance, the rural communities. The study also questions the often taken-for-granted image of a rigidly polarized city in view of empirical evidence that indicates the multiple and complex economic and political links between the new neighbourhoods and the broader urban society. Finally, isolation from middle class areas in the city does not necessarily lead to the exclusion of the whole peripheral urban population from urban life, urban institutions and urban culture. These become increasingly present in the new neighbourhoods and available for the majority of the residents. The main conclusion is that Istanbul contains a number of such edge cities, which have powerful integrating and urbanizing influences on individuals. Les migrants et l'évolution de la périphérie urbaine: relations sociales, diversité culturelle et espace public dans les nouveaux quartiers d'Istanbul La présente étude examine la dynamique des changements socioculturels dans un quartier de la périphérie d'Istanbul, une « ville-lisière » (edge city) caractérisée par sa mixité ethnique, son hétérogénéité culturelle, sa différenciation sociale et son espace multifonctionnel. L'un des principaux axes de la présente étude est la nature changeante des relations sociales au sein des groupes traditionnels. Premièrement, bien que la parenté, hem,eri (le lieu d'origine), et la solidarité des résidants des quartiers restent essentiels dans la vie des migrants, la participation à ces groupes devient plus volontaire et les liens entre ses membres sont moins contraints. Deuxièmement, les regroupements ethniques et religieux au sein des quartiers ne constituent pas toujours des communautés privées, autoritaires et patriarcales. Ce qui semble généralement être une fragmentation rigide en communautés est souvent une marque de la diversité culturelle pour les résidants de la localité. Le pluralisme des associations permet aux personnes de revendiquer différentes identités ethniques, religieuses, politiques et culturelles. Troisièmement, même s'ils ne peuvent soutenir la comparaison avec leurs équivalents urbains habités par la classe moyenne, ces nouveaux quartiers offrent davantage de possibilités et d'espace public pour les rencontres entre membres de la localité que les communautés rurales par exemple. L'étude remet aussi en question l'image que l'on a souvent d'une ville rigide et polarisée en faisant état des témoignages empiriques qui attestent de la complexité et de la multitude des liens économiques et politiques entre les nouveaux quartiers et la société urbaine au sens large. Enfin, être isolé des zones urbaines où habitent les classes moyennes n'entraîne pas nécessairement l'exclusion de l'ensemble de la population urbaine vivant en périphérie de la vie, des institutions et de la culture urbaines qui sont de plus en plus présentes dans les nouveaux quartiers et accessibles à la majorité des résidants. La conclusion principale est qu'Istanbul comporte un certain nombre de villes-lisières de ce genre, dont l'influence sur les habitants en matière d'intégration et d'urbanisation est très forte. Relaciones sociales, diversidad cultural y espacio público en los nuevos vecindarios de Estambul En este estudio se examina la dinámica del cambio sociocultural en los vecindarios periféricos de Estambul, una "ciudad suburbana"étnicamente mixta, culturalmente heterogénea, socialmente diferenciada y espacialmente multifuncional. Uno de los principales centros de atención de este estudio es la naturaleza cambiante de las relaciones sociales en los grupos tradicionales. Si bien la buena voluntad, el hem,eri (lugar de origen) y la solidaridad de los vecinos siguen siendo fundamentales en la vida de los migrantes, la participación en estos grupos se convierte en una cuestión de carácter voluntario y los vínculos entre los mismos no son obligatorios. En segundo lugar, las agrupaciones étnicas y religiosas en el vecindario no siempre son comunidades exclusivas, autoritarias o patriarcales. Lo que, generalmente, parece ser una fragmentación comunitaria rígida es más bien una diversidad cultural de los residentes de la localidad. El pluralismo asociativo que existe en el vecindario permite a las personas preservar diversas identidades étnicas, religiosas, políticas y culturales. En tercer lugar, si bien salen desfavorecidos en la comparación con sus equivalentes de la clase media en la ciudad, los nuevos vecindarios proveen mayores oportunidades y espacio público para la interacción de sus miembros de la localidad que, por ejemplo, las comunidades rurales. Este estudio también cuestiona la imagen a priori de una ciudad rígidamente polarizada ya que hay pruebas que indican los múltiples y complexos vínculos económicos y políticos existentes entre los nuevos vecindarios y la sociedad urbana amplia. Finalmente, el aislamiento de zonas de la clase media en la ciudad no conduce necesariamente a su exclusión de la vida, instituciones y cultura urbanas. Estas están omnipresentes en los nuevos vecindarios y disponibles para la mayoría de sus residentes. La principal conclusión de este artículo es que Estambul contiene una serie de estas ciudades periféricas, que tienen poderosas influencias integradoras y urbanizadoras en las personas. [source] Families and family study in international perspectiveJOURNAL OF MARRIAGE AND FAMILY, Issue 5 2004Bert N. Adams Many changes are occurring in the world's families. Some observers feel that the changes are destructive, whereas others see them as leading to new opportunities and understanding. Issues in international family studies include regional limitations and the various aspects of doing research cross-culturally. Knowledge regarding certain categories of families, inheritance, and the social psychology of families is incomplete. There are, however, some universals and universal or worldwide changes, including movement toward individual partner choice, more divorces, lower fertility, and greater opportunities for women. [source] Changes in Adolescents' Interpersonal Experiences: Are They Being Prepared for Adult Relationships in the Twenty-First Century?JOURNAL OF RESEARCH ON ADOLESCENCE, Issue 1 2002Reed W. Larson Trends across nations suggest that adulthood in the future will require greater social versatility, including abilities to function in relationships that are less scripted by community norms and that bridge multiple social worlds. This article assesses whether current changes in adolescents' interpersonal experience are likely to give them the social resources and competencies they will need. Changes in families are making them smaller, more diverse in social capital, and more responsive to adolescents. Changes in adolescents' nonfamily experience include more time in institutional settings; more involvement with peers; and more cycles of developing (and ending) relationships with a heterogeneous set of adults, friends, and, for many, romantic partners. The analysis suggests that these changes will provide many youth with greater opportunities to develop the more versatile interpersonal resources required in the future, but that many adolescents will have restricted opportunities to acquire these resources. [source] Improving Wikipedia's accuracy: Is edit age a solution?JOURNAL OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE AND TECHNOLOGY, Issue 2 2008Brendan Luyt Wikipedia is fast becoming a key information source for many despite criticism that it is unreliable and inaccurate. A number of recommendations have been made to sort the chaff from the wheat in Wikipedia, among which is the idea of color-coding article segment edits according to age (Cross, 2006). Using data collected as part of a wider study published in Nature, this article examines the distribution of errors throughout the life of a select group of Wikipedia articles. The survival time of each "error edit" in terms of the edit counts and days was calculated and the hypothesis that surviving material added by older edits is more trustworthy was tested. Surprisingly, we find that roughly 20% of errors can be attributed to surviving text added by the first edit, which confirmed the existence of a "first-mover" effect (Viegas, Wattenberg, & Kushal, 2004) whereby material added by early edits are less likely to be removed. We suggest that the sizable number of errors added by early edits is simply a result of more material being added near the beginning of the life of the article. Overall, the results do not provide support for the idea of trusting surviving segments attributed to older edits because such edits tend to add more material and hence contain more errors which do not seem to be offset by greater opportunities for error correction by later edits.

[source] Natural disaster and mental health in AsiaPSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 2 2004MASAHIRO KOKAI md Abstract, The purpose of the present article was to review the literature on disaster mental health in relation to natural disasters such as earthquakes, volcanic eruptions, typhoons and cyclones throughout Asia. Articles reviewed show that disaster psychiatry in Asia is beginning to emerge from and leave behind the stigma attached to mental health. The emergence of the acceptance of disaster mental health throughout Asia can be attributed in part to the acceptance of the notion of post-traumatic stress disorder (PTSD). This has allowed greater involvement of mental health professionals in providing ongoing support to survivors of natural disasters as well as providing greater opportunities for further research. Also, articles reviewed in the present paper commonly suggested the need for using standardized diagnostic tools for PTSD to appropriately interpret the discrepancy of results among studies. The importance of post-disaster support services and cultural differences is highlighted. [source] The talking touchscreen: A new approach to outcomes assessment in low literacyPSYCHO-ONCOLOGY, Issue 2 2004Elizabeth A. Hahn Purpose. Cancer patients who are deficient in literacy skills are particularly vulnerable to experiencing different outcomes due to disparities in care or barriers to care. Outcomes measurement in low literacy patients may provide new insight into problems previously undetected due to the challenges of completing paper-and-pencil forms. Description of study. A multimedia program was developed to provide a quality of life assessment platform that would be acceptable to patients with varying literacy skills and computer experience. One item at a time is presented on the computer touchscreen, accompanied by a recorded reading of the question. Various colors, fonts and graphic images are used to enhance visibility, and a small picture icon appears near each text element allowing patients to replay the sound as many times as they wish. Evaluation questions are presented to assess patient burden and preferences. Results. An ethnically diverse group of 126 cancer patients with a range of literacy skills and computer experience reported that the ,talking touchscreen' (TT) was easy to use, and commented on the usefulness of the multimedia approach. Clinical implications. The TT is a practical, user-friendly data acquisition method that provides greater opportunities to measure self-reported outcomes in patients with a range of literacy skills.

[source] Resources, population and migration in the Pacific: Connecting islands and rimASIA PACIFIC VIEWPOINT, Issue 3 2009Brian Opeskin Abstract This article examines international migration in the Pacific and argues that there should be still greater opportunities for the people of Pacific countries to migrate between their home states and the developed states of the Pacific Rim. The case for borders that are more permeable to human migration is based in part on the common Pacific predicament of poor resource endowments, rapidly growing populations, depletion and degradation of existing resources, and threats posed by anthropogenic climate change. Coupled with this is a history of colonisation that has left some Pacific peoples with liberal access to economic opportunities in developed states by virtue of their citizenship or preferential visa status, while others have no such opportunities. Both New Zealand and the United States have been reasonably generous in facilitating migration from Polynesia and Micronesia. It is Australia that stands out as the Pacific neighbour with the greatest capacity to develop new migration streams. The seasonal worker scheme announced by the Australian Government in August 2008 takes a cautious but valuable step along this path, yet there is scope for further expanding Pacific access by broadening the geographical, temporal and material scope of existing migration arrangements. [source] Risk perception and risky choice: Situational, informational and dispositional effectsASIAN JOURNAL OF SOCIAL PSYCHOLOGY, Issue 2 2003Xiao-Fei Xie We investigated how situational (gain,loss), informational (opportunity,threat framing) and dispositional (achievement motive and avoidance motive) variables affected opportunity,threat perception and risky choice in managerial decision-making contexts. In Study 1, the risk preference of the participants showed a reflection effect due to situational differences (gain or loss) and a partial framing effect caused by presenting the same choice information in terms of either opportunities or threats. However, both effects were in the opposite direction of predictions from prospect theory. Gains and positive framing enhanced risk-seeking preference whereas losses and negative framing augmented risk-averse preference. Risk-seeking choices were mediated by opportunity perception whereas risk-averse choices were mediated by threat perception. In Study 2, the participants high in achievement motive perceived greater opportunities in a negative situation, and the participants high in avoidance motive perceived greater threats in a positive situation, suggesting that ambition (achievement motive) operates more significantly in the face of adversities whereas cautiousness (avoidance motive) functions more significantly in prosperity. [source] What are the learning affordances of 3-D virtual environments?BRITISH JOURNAL OF EDUCATIONAL TECHNOLOGY, Issue 1 2010Barney Dalgarno This article explores the potential learning benefits of three-dimensional (3-D) virtual learning environments (VLEs). Drawing on published research spanning two decades, it identifies a set of unique characteristics of 3-D VLEs, which includes aspects of their representational fidelity and aspects of the learner,computer interactivity they facilitate. A review of applications of 3-D VLEs is presented, leading to the identification of a series of learning affordances of such environments. These affordances include the facilitation of tasks that lead to enhanced spatial knowledge representation, greater opportunities for experiential learning, increased motivation/engagement, improved contextualisation of learning and richer/more effective collaborative learning as compared to tasks made possible by 2-D alternatives. The authors contend that the continued development of and investment in 3-D games, simulations and virtual worlds for educational purposes should be considered contingent on further investigation into the precise relationships between the unique characteristics of 3-D VLEs and their potential learning benefits. To this end, they conclude by proposing an agenda or ,roadmap' for future research that encompasses empirical studies aimed at exploring these relationships, as well as those aimed at deriving principles and guidelines to inform the design, development and use of 3-D virtual environments for learning. [source] Demand for Wildlife Hunting in British ColumbiaCANADIAN JOURNAL OF AGRICULTURAL ECONOMICS, Issue 1 2005Lili Sun We present estimates of the demand for hunting licenses by residents and nonresidents in British Columbia for the period 1971,2000. We obtain estimates of both short-run and long-run price elasticities and discuss their revenue implications for future fee increases. We find the demand by nonresidents to be strongly correlated with U.S. income variation over the business cycle, but find no such role for cyclical income variation for resident hunters. The ability of the government to increase revenues from resident hunters turns out to be limited, particularly in the long run, while greater opportunities exist for raising revenues from U.S. hunters as short- and long-run price elasticities of demand are quite inelastic. We argue that conservation surcharges on foreign hunters are one way of capturing more of the resource rent. Nous analysons la demande de permis de chasse par les résidants et les non-résidants de Colombie-Britannique pour la période 1971,2000. Nous présentons des élasticités de court terme et de long terme que nous utilisons ensuite pour évaluer l'effet d'augmenter le coût des permis sur les revenus générés par la vente de ces permis. La demande des non-résidants est fortement corrélée aux fluctuations des revenus américains, mais les variations cycliques du revenu n'ont pas la même incidence sur la demande des chasseurs locaux. La capacité du gouvernement d'augmenter ses revenus en augmentant les coûts des permis des chasseurs locaux est restreinte, surtout à long terme. Ce constat ne s'applique pas aux chasseurs américains puisque leur demande de permis est inélastique, à court terme comme à long terme. Des frais supplémentaires de conservation imposés aux chasseurs étrangers permettraient au gouvernement de s'accaparer une part plus importante de la rente associée à la ressource. [source] EXPERIMENTAL MANIPULATION OF SEXUAL SELECTION PROMOTES GREATER MALE MATING CAPACITY BUT DOES NOT ALTER SPERM INVESTMENTEVOLUTION, Issue 4 2009Helen S. Crudgington Sexual selection theory makes clear predictions regarding male spermatogenic investment. To test these predictions we used experimental sexual selection in Drosophila pseudoobscura, a sperm heteromorphic species in which males produce both fertile and sterile sperm, the latter of which may function in postmating competition. Specifically, we determined whether the number and size of both sperm types, as well as relative testis mass and accessory gland size, increased with increased sperm competition risk and whether any fitness benefits could accrue from such changes. We found no effect of sexual selection history on either the number or size of either sperm morph, or on relative testis mass. However, males experiencing a greater opportunity for sexual selection evolved the largest accessory glands, had the greatest mating capacity, and sired the most progeny. These findings suggest that sterile sperm are not direct targets of sexual selection and that accessory gland size, rather than testis mass, appears to be an important determinant of male reproductive success. We briefly review the data from experimental sexual selection studies and find that testis mass may not be a frequent target of postcopulatory sexual selection and, even when it is, the resulting changes do not always improve fitness. [source] Swallowing Disorders in the Elderly ,THE LARYNGOSCOPE, Issue 4 2002Joshua S. Schindler MD Abstract Changes that occur as a natural part of senescence in the complex action of deglutition predispose us to dysphagia and aspiration. As the "baby-boomers" begin to age, the onset of swallowing difficulties will begin to manifest in a greater number of our population. Recent advances in the evaluation of normal and abnormal swallowing make possible more precise anatomical and physiological diagnoses. Coupled with an understanding of swallowing physiology, such detailed evaluation allows greater opportunity to safely manage dysphagia with directed therapy and appropriate surgical intervention. The current study is a discussion of the changes that occur in deglutition with normal aging, contemporary evaluation of swallowing function, and some of the common causes of dysphagia in elderly patients.
