Survey on Classification of Online Reviews Based on Social Networking

For what reason would individuals like to vote in favor of or against content at some online groups and not at others? Social foraging hypothesis, mainly research on insect and other animal information sharing behavior, it provides new approach. Obtaining ideas from social searching hypothesis, this survey suggests that four components drive individuals' goal to vote online content (positive or negative): 1) altruistic intentions; 2) identification with the community; 3) data quality; and 4) learning self-adequacy. The survey show was tried in a study of online news groups. It found that positive voting goal was anticipated by altruistic motives, identification with the community, and learning self-adequacy. Data quality is critical for positive voting; however, it works in a indirect way through cultivating more group recognition. Negative voting expectation was anticipated by altruistic motives and data quality. Earlier research has connected through searching hypothesis to people acting alone, e.g., when an individual uses Google to search for data on the web. This survey grows the utilization of searching hypothesis to the group surroundings where people give votes to impact others in their selected group. The discoveries advance our insight about content voting and give suggestions to experts of voting systems

Content Modelling for unbiased Information Analysis

Content is the form through which the information is conveyed as per the requirement of user. A volume of content is huge and expected to grow exponentially hence classification of useful data and not useful data is a very tedious task. Interface between content and user is Search engine. Therefore, the contents are designed considering search engine\u27s perspective. Content designed by the organization, utilizes user’s data for promoting their products and services. This is done mostly using inorganic ways utilized to influence the quality measures of a content, this may mislead the information. There is no correct mechanism available to analyse and disseminate the data. The gap between Actual results displayed to the user and results expected by the user can be minimized by introducing the quality check for the parameter to assess the quality of content. This may help to ensure the quality of content and popularity will not be allowed to precede quality of content. Social networking sites will help in doing the user modelling so that the qualitative dissemination of content can be validated

Why do people share online? Online disinhibition effect in the context of the virtual community of Reddit

For the past two decades, the growth of Internet has been truly exponential. Although there is nothing deterministic about the effects of this technological revolution, it is evident that the Internet is changing our behavior in fundamental ways. One recent expression of the Internet culture is the website reddit.com, which describes itself as "the front page of Internet". In their personal stories the users of Reddit share everything from their financial problems to their illegal venture. And to every touching story about struggling with depression there is a startlingly rude joke about the said depression. What motivates people to share their stories in Reddit even though not necessarily a single user will remember their username? One of the biggest influencers on how we behave online is the online disinhibition effect. To unerstand the site and its communications in a fundamental way, I decided to study the online disinhibition effect in the virtual community of Reddit through netnography. For a period of one year, I participated in the community, aiming to document the experiences of others and myself on the site. According to my research the characteristics typical to Reddit communications: anonymity, lack of cues, and text-basedness affect change the way we communicate on the site, compared to how we communicate face-to-face. When communicating on the site, redditors are able to dissociate themselves from their daily life and identity and assume instead communications' culture, values and morals associated with the virtual community of Reddit. Thus, online disinhibition effect in Reddit means not abandoning all norms but conforming to new ones. All of this is meaningful for the community members because disinhibited behavior gives redditors feelings of empowerment or perceived capabilities in coping with various challenges and overcoming obstacles. Online disinhibition can create empowering experiences through venting, finding similar others, and heightened feelings of self-efficacy as well as receiving emotional support. Thus, people behave disinhibitedly online to feel more powerful and capable. My research contributes to the field of consumer research, although I borrow concepts and ideas vastly from the fields of social psychology and communications studies. Through understanding the phenomena of online disinhibition better, I hope to contribute to the discourse on virtual communities and brand communitie

Nutritional status and socioeconomic change among Toba and Wichí populations of the Argentinean Chaco

The prevalence of overweight and obesity is growing at an accelerated pace in disadvantaged populations. Indigenous populations all over the world, whose lifestyle is changing rapidly and drastically, seem to be particularly prone to show an increased prevalence of overweight and its co-morbidities among adults. The aim of this study was to evaluate the association between socioeconomic and nutritional statuses in adults of two indigenous populations of the Argentine Gran Chaco: the Toba and Wichí of the province of Formosa. Originally hunter-gatherers, they are now more settled and engage in temporary wage labor and local political positions. A total of 541 adults (>20 years old) participated in the study. Almost 50% of the adult Toba and 34% of the adult Wichí were overweight and 10% of adults in both populations were obese. Socioeconomic status was positively associated with body mass index in both populations. Furthermore, political connectedness with the non-indigenous sector, as in the case of community leaders, was highly correlated with obesity. Differences within and between groups can be explained by biocultural factors that include gender, diet (foraged vs store-bought), lifestyle (sedentary vs more active), and history of political power. Our study highlights the interactions among social, cultural, and political economic variables, such as political hierarchies within the group or degree of social connectedness with community leaders. By making these variables an integral part of our analysis and interpretation, we hope to improve our understanding of the situation of indigenous populations in transition. © 2009 Elsevier B.V.

Economics, Biology, and Culture: Hodgson on History

This book addresses what the author claims, with considerable justification, to be the foremost challenge confronting the social and behavioral sciences today: the problem of historical specificity. Hodgson poses the question by asking whether we need different theories to understand social and economic behavior in different societies at different stages of their development. He answers the question in the affirmative, and criticizes the economics profession for suggesting that there is one universal model or theory equally suited to all economies and societies at all times. He faults the profession further for no longer worrying much or conducting serious debate about this issue, a development he attributes to the eclipse and eventual demise of institutionalism and historical economics in England, Germany, and the United States

Novel Idea Generation, Collaborative Filtering, and Group Innovation Processes

Organizations that innovate encounter challenges due to the complexity and ambiguity of generating and making sense of novel ideas. Exacerbated in group settings, we describe these challenges and propose potential solutions. Specifically, we design group processes to support novel idea generation and selection, including use of a novel-information discovery (NID) tool to support creativity and brainstorming, as well as group support system and collaborative-filtering tools to support evaluation and decision making. Results indicate that the NID tool increases efficiency and effectiveness in creative tasks and that the collaborative-filtering tool can support the decision-making process by focusing the group’s attention on ideas that might otherwise be neglected. Combining these two novel tools with group processes provides valuable contributions to both research and practice

Rationality, irrationality and economic cognition

This paper contrasts the modern use of the assumption that rationality as reflected in simple models of utility and profit maximization guides individual economic behaviour to literature both between 1890 and 1930 which sharply challenged the use of such an assumption and later literature in economic psychology from Herbert Simon onwards which sees economic (and other) cognitive processes in different ways. Some of the earlier literature proposed objective and operational notions of rationality based on the availability of information, ability to reason (cognitive skills), and even morality. Learning played a major role in individuals achieving what was referred to as complete rationality. I draw on these ideas, and suggest that developing models in which economic agents have degrees (or levels) of economic cognition which are endogenously determined could both change the perceptions economists have on policy matters and incorporate findings from recent economic psychology literature. This would remove the issue of whether economic agents are dichotomously rational or irrational, and instead introduce continuous metrics of cognition into economic thinking. Such an approach also poses the two policy issues of whether raising levels of economic cognition should be an objective of policy and whether policy interventions motivated by departures from full economic cognition should be analyzed
