Point-of-Interest recommendation is an efficient way to explore interesting unknown locations in social media mining of social networks. In order to solve the problem of sparse data and inaccuracy of single user model, we propose a User-City-Sequence Probabilistic Generation Model (UCSPGM) integrating a collective individual self-adaptive Markov model and the topic model. The collective individual self-adaptive Markov model consists of three parts such as the collective Markov model, the individual self-adaptive Markov model and the self-adaptive rank method. The former determines the topic sequence for all users in system and mines the behavioral patterns of users in a large environment. The later mines behavioral patterns for each user in a small environment. The last determines a self-adaptive-rank for each user in niche. We conduct a large amount of experiments to verify the effectiveness and efficiency of our method.

Making decisions in a social context often requires weighing one's own wants against the needs and preferences of others. Adults are adept at incorporating multiple contextual features when deciding how to trade off their welfare against another. For example, they are more willing to forgo a resource to benefit friends over strangers (a feature of the individual) or when the opportunity cost of giving up the resource is low (a feature of the situation). When does this capacity emerge in development? In Experiment 1 (N = 208), we assessed the decisions of 4- to 10-year-old children in a picture-based resource tradeoff task to test two questions: (1) When making repeated decisions to either benefit themselves or benefit another person, are children’s choices internally consistent with a particular valuation of that individual? (2) Do children value friends more highly than strangers and enemies? We find that children demonstrate consistent person-specific welfare valuations and value friends more highly than strangers and enemies. In Experiment 2 (N = 200), we tested adults using the same pictorial method. The pattern of results successfully replicated, but adults’ decisions were more consistent than children’s and they expressed more extreme valuations: relative to the children, they valued friends more and valued enemies less. We conclude that despite children’s limited experience allocating resources and navigating complex social networks, they behave like adults in that they reference a stable person-specific valuation when deciding whether to benefit themselves or another and that this rule is modulated by the child’s relationship with the target.

Gendered Expectations

This is the first data chapter. In this chapter, respondents who are described as true believers in the gender structure, and essentialist gender differences are introduced and their interviews analyzed. They are true believers because, at the macro level, they believe in a gender ideology where women and men should be different and accept rules and requirements that enforce gender differentiation and even sex segregation in social life. In addition, at the interactional level, these Millennials report having been shaped by their parent’s traditional expectations and they similarly feel justified to impose gendered expectations on those in their own social networks. At the individual level, they have internalized masculinity or femininity, and embody it in how they present themselves to the world. They try hard to “do gender” traditionally.

Absorptive capacity is a common barrier to knowledge transfer at the individual level. However, technology absorptive capacity can enhance an individual’s learning behaviour. This study investigates that technology readiness, the tools for knowledge sources, social influences, and social networks influence an individual’s absorptive capacity on an adaptation of the individual learning behaviour. A quantitative approach is used to assess the presence of a causal relationship from the constructs mentioned above. Data were collected from university students in Australia to examine the hypotheses. With 199 responses, a partial least squares structural equation modelling (PLS-SEM) approach was used for the analysis. The results generated mixed findings. Individual’s technological belief in optimism and innovation and social influences had a significantly weaker effect on individual absorptive capacity, which in turn had a significantly weaker impact on their learning behaviour.

Abstract The article examines the nature and importance of using aesthetic and therapeutic concept and educational logotherapy, in particular, for creating a special emotionally comfortable socioeducational environment for primary education The author has represented inteipretation of foreign scholars' views (J. Bugental, V. Frankl, A. Maslow, R. May, J. Moreno, C. Rogers et al) on such terms as “communication ”, “aesthetotherapy ”, “educational logotherapy” etc. An attempt has been made to analyze the social coTitent of pedagogical activity in the context of using logotherapy in primary school based on an agogical paradigm. In the scope of the article, the specific of using the therapeutic metaphor in the educational environment of primary' school has been represented as well as the basic stages of its implementation have been determined. These stages are the following: description of the storyline, persuasion and binding. The author has defined the role of the “living metaphors” in organization of the therapeutic interaction between the teacher and primary' schoolchildren. Particular attention has been paid to formation of the humanistic competency among primary schoolchildren; this competency is to be based on their understanding of the following philosophical and pedagogical categories: a norm (as a means and a results of pupils' social activity), freedom (as a mean and a result of individual self-expression among primary schoolchildren) and happiness (as an individual self-expression among primaryr schoolchildren). The author has assessed the role of deflection method and paradoxical intention for the social development of the pupil and further formation of the individual. Additional attention has been paid to determination of the socioeducational and psychological and pedagogical potential of such leading method in logotherapy as “The Socratic dialogue” (or “The Socratic circle”): as well have been highlighted the main stages of its implementation: consent (search for what pupil may agree), doubt (an expression of doubts towards weak arguments of interlocutor) and arguments (the teacher must convey' one’s opinion, without any resistance from the child): have been represented different various algorithms of its realization: the method of “aquarium”, “panel method” and “questioning technique”.

The Way

In the field of Deaf Geographies, one neglected area is that of the individual deaf body and how individual deaf bodies can produce deaf space in isolation from one another. Much of the work published in the field talks about collectively or socially produced deaf spaces through interaction between two or more deaf people. However, with deaf children increasingly being educated in mainstream schools with individual provisions, and the old social networks and institutions of deaf communities coming under threat by the closure of deaf clubs and changing work practices, more research on the way in which individuals can produce their own deaf spaces and navigate those spaces is needed. In this paper, I outline two possible theoretical approaches, that of Lefebvre’s productive gestures to produce social space, and Bourdieu’s habitus, capital and hexis. I suggest that these theories can be productively utilised to better understand the individual basis of the production of deaf spaces.

Social Networks (SNs) bring new types of privacy risks threats for users; which developers should be aware of when designing respective services. Aiming at safeguarding users’ privacy more effectively within SNs, self-adaptive privacy preserving schemes have been developed, considered the importance of users’ social and technological context and specific privacy criteria that should be satisfied. However, under the current self-adaptive privacy approaches, the examination of users’ social landscape interrelated with their privacy perceptions and practices, is not thoroughly considered, especially as far as users’ social attributes concern. This study, aimed at elaborating this examination in depth, in order as to identify the users’ social characteristics and privacy perceptions that can affect self-adaptive privacy design, as well as to indicate self-adaptive privacy related requirements that should be satisfied for users’ protection in SNs. The study was based on an interdisciplinary research instrument, adopting constructs and metrics from both sociological and privacy literature. The results of the survey lead to a pilot taxonomic analysis for self-adaptive privacy within SNs and to the proposal of specific privacy related requirements that should be considered for this domain. For further establishing of our interdisciplinary approach, a case study scenario was formulated, which underlines the importance of the identified self-adaptive privacy related requirements. In this regard, the study provides further insight for the development of the behavioral models that will enhance the optimal design of self-adaptive privacy preserving schemes in SNs, as well as designers to support the principle of PbD from a technical perspective.

The term strategic essentialism, coined by Spivak, is generally understood as “a political strategy whereby differences (within Group) are temporarily downplayed, and unity assumed for the sake of achieving political goals.” On the other hand, essentialism focuses that everything in this world has an intrinsic and immutable essence of its own. The adaption of a particular “nature” of one group of people by way of sexism, culturalization, and ethnification is strongly linked to the idea of essentialism. Mulk Raj Anand’s Bakha is dictated as an outcast by the institutionalized hierarchy of caste practice. He is essentialized as an untouchable by attributing to him the characteristic of dirt and filth. However, unlike other untouchables, Bakha can apprehend the difference between the cultured and uncultured, dirt and cleanliness. Via an analysis of Anand’s “Untouchable,” the present article aims to bring to the forefront the horrid destruction of the individual self that stems from misrepresentations of personality. Through strategic essentialism, it unravels Bakha’s contrasting nature as opposed to his pariah class, defied by his remarkable inner character and etiquette. The term condemns the essentialist categories of human existence. It has been applied to decontextualize and deconstruct the inaccurately essentialized identity of Bakha, which has made him a part of the group he does not actually belong to.

Social networking users are presented with a plethora of profile and privacy settings; most of which are left defaulted. As a result, there is little understanding of the fields that make up the user profile, the privacy settings available to safeguard the user, and the ramifications of not changing the same. Concerns relating to the unprecedented quantities of Personally Identifiable Information being stored need to be addressed. By employing a risk matrix to a social media profile, a user could be alerted to the potential dangers of the information being contained within the profile. By adapting this tool, the risks to the individual user of a social media profile will be minimised.
