Game Theory Based Correlated Privacy Preserving Analysis in Big Data

Privacy preservation is one of the greatest concerns in big data. As one of extensive applications in big data, privacy preserving data publication (PPDP) has been an important research field. One of the fundamental challenges in PPDP is the trade-off problem between privacy and utility of the single and independent data set. However, recent research has shown that the advanced privacy mechanism, i.e., differential privacy, is vulnerable when multiple data sets are correlated. In this case, the trade-off problem between privacy and utility is evolved into a game problem, in which payoff of each player is dependent on his and his neighbors’ privacy parameters. In this paper, we firstly present the definition of correlated differential privacy to evaluate the real privacy level of a single data set influenced by the other data sets. Then, we construct a game model of multiple players, in which each publishes data set sanitized by differential privacy. Next, we analyze the existence and uniqueness of the pure Nash Equilibrium. We refer to a notion, i.e., the price of anarchy, to evaluate efficiency of the pure Nash Equilibrium. Finally, we show the correctness of our game analysis via simulation experiments

Gender stereotypes in leadership: Analyzing the content and evaluation of stereotypes about typical, male, and female leaders

IntroductionPrevious research often examined gender stereotypes in leadership with ratings on predetermined gendered characteristics concerning leaders’ agency and communality (i.e., explicit measures). The aim of the present study was to broaden the understanding of gender stereotypes in leadership by taking more subtle approaches, that focus on what men and women actually ascribe to typical, male, and female leaders and how they implicitly evaluate them.MethodsAn online survey collected (a) free associations which reflect social representations (e.g., dominant, empathic), (b) evaluations of the given associations as negative, neutral, or positive, and (c) ratings on Peabody’s semantic differential combining non-gendered adjective pairs to an evaluative component of a typical leader, a male leader, and a female leader.ResultsUsing the approach of social representations by analyzing 2,842 free associations from 194 participants shows the predominant gender stereotypes. Ratings of the free associations revealed that women evaluate characteristics associated with female leaders more negatively than those associated with typical leaders and male leaders. By contrast, using the evaluative component of non-gendered adjective pairs shows that typical and female leaders were often rated more positively than male leaders and that women were more likely to devalue male leaders.DiscussionDirectly asking about leaders (i.e., associations) might retrieve participants’ gender stereotypes, whereas when using non-direct questions (i.e., evaluation component of adjective pairs) gender stereotypes might be less prominent. Thus, when evaluating leaders, practitioners and researchers should consider whether these evaluations were obtained explicitly or implicitly to assess potential influences of gender stereotypes

Analysis of the Epidemiology of Playground-Related Injuries in Relation to Existing Playground Safety Standards: How Should We Address Safe Play?

Play is widely acknowledged to provide children with various physical, emotional, social, and intellectual benefits. However, playgrounds are reported to be the leading location of unintentional recreation injuries to children aged 1-10. Over 185,000 children annually are being treated in emergency departments for playground injuries. These play-related injuries have remained stagnant according to epidemiology studies of the past three decades. Past epidemiological studies for playground injuries have been based on emergency department data, resulting in an underrepresentation of the magnitude of injuries occurring. This study utilizes the unique setting of an entire school district, providing a more comprehensive understanding of injury patterns on playgrounds. The data in this study is useful for interpreting injury patterns in the context of existing safety standards and guidelines for playgrounds. Playground injury mitigation efforts are based largely on current epidemiological studies derived from emergency department databases. Thus, efforts focus on the prevention of severe head injuries. This study has established an 88% incident rate outside of severe playground injuries within the school district. Analysis has shown that upper extremity injuries are twice as likely to require outside medical attention as injuries to other body regions, including the head and neck. These findings may indicate that there are gaps in current injury mitigation efforts that should be addressed by standards and guidelines organizations. Given what is known about playground injury patterns from past studies, and new data from the epidemiology of the current study, recommendations can be made to enhance the safety of childhood play

An investigation of social capital in Britain using small area estimation analysis

Social Capital is considered an important asset for development, both at local and higher levels, and has been explored across the social sciences for decades. Attempts to define and measure it in increasingly precise ways continue in order to place it at the centre of policymaking. Indeed, it is considered a precious capital in times where resources are becoming scarce. This thesis investigates the dimensions of social capital and estimates them at small area level for England and Wales in 2011. The first step is the identification of three factors measuring membership, citizenship and politics and neighbourliness dimensions using survey data and a Confirmatory Factor Analysis. The second step is to test the hypothesis that other individual characteristics and geographical characteristics may influence levels of these factors. Complex Multilevel models with individual covariates and area-level covariates from the Census and administrative sources confirm the hypothesis: the factors depend on age, gender, ethnicity, religion, marital status, socio-economic class, employment, state of health and education at individual level and ethnic diversity and economic profile at area level. Lastly, Multilevel Model results have been used as a starting point for the final synthetic estimates at small area for all the Middle Super Output Areas of the average levels of the three factors. While Membership and Citizenship and Politics social capital show higher differentials, Neighbourliness seems to be more spread and, on average, higher than the other two factors across the two countries

Leadership Strategies for Adapting to Changes in Ontario Colleges: Tensions, Dilemmas, and Opportunities for Continuing Education Deans/Administrative Leaders

This exploratory case study explores unique leadership challenges facing Ontario college Continuing Education leaders as they navigate institutional responses to contemporary changes in the higher education landscape. Nine Ontario college deans/administrative leaders participated in semi-structured interviews that were analyzed using a modified version of constant comparative analysis. Adopting the theoretical perspectives of sensemaking and identity from an Interpretive stance, the analysis leads to the presentation of a conceptual model that represents the interpretation of these leaders’ experiences. The conceptual model that emerged from this study adopts the position that sensemaking resolves identity ambiguities and is triggered by leadership challenges. These leaders’ identities demonstrate passionate advocacy for lifelong learning; a commitment to serving their students, their communities and their teams; and a connection to provincial colleagues that counteracts a perception of local isolation. Furthermore, participants’ leadership challenges include experiences of complexity, constant change, and varying degrees of institutional marginalization. Finally, despite commonalities of identity construction and leadership challenges, there is diversity in these leaders’ approaches to their roles, as narrated in their interviews and subsequently interpreted as distinct metaphorical cameos. The study findings suggest a similarity that Continuing Education leaders may have with a “reframing” model for approaching leadership challenges in higher education. This study contributes to the field of Educational Leadership, and presents an opportunity to gain a deeper understanding of the unique challenges and opportunities that Continuing Education leaders in Ontario colleges encounter. Recommendations suggest future research that may further develop an even deeper understanding of sensemaking phenomena as applied to leadership in the higher education setting
