The work presented in this article brings into light the security issues with NoSQL databases- MongoDB, HBase and Cassandra. A literature survey is carried out to identify the modern world scenarios of the applications using NoSQL databases and limitations are identified. A solution is proposed by designing a framework to achieve security for the web crawler applications using Cassandra, a NoSQL data store. Experimental results are presented to show the effectiveness of the work by designing an appropriate algorithm to trigger security for scalable web crawler architecture. Amazon Web Services (AWS), a familiar cloud platform, and bitnami cloud hosting services are used to procure the required servers and virtual machines. Performance changes on the virtual machines are brought into consideration before and after encrypting and decrypting the voluminous data and an improvement in efficiency is observed with the proposed model.

The massive amount of data collected by various fields is a challenging aspect for analysis using the available storage technologies. Relational databases are a traditional approach of data storage more suitable for structured data formats and are constrained by ACID properties. As the modern world data in the form of word documents, pdf files, audio and video formats is unstructured, where tables and schema definition is not a major concern. Relational databases such as Mysql may not be suitable to serve such Bigdata. An alternate approach is to use the emerging Nosql databases. This paper presents a comparative analysis of Nosql types such as Hbase, Mongodb, Simple DB and Big Table with relational database like Mysql and specifies their limitations when applied to real world problems. It also proposes solution to overcome these limitations using an integrated data store which serve to be beneficial over the mentioned Nosql and Mysql stores in terms of efficiently implementing simple and complex queries yielding better performance.

The qualitative and clear definition of the legal regime of the capital of Ukraine, the hero city of Kyiv, is influenced by its legislative enshrinement, however, it should be noted that discussions are ongoing and one of the reasons for the unclear legal status of the capital is the ambiguity of current legislation in this area. Separation of the functions of the city of Kyiv, which are carried out to ensure the rights of citizens of Ukraine and the functions that guarantee the rights of the territorial community of the city of Kyiv. In the modern world, in legal doctrine and practice, the capital is understood as the capital of the country, which at the legislative level received this status and, accordingly, is the administrative and political center of the state, which houses the main state bodies and diplomatic missions of other states. It is the identification of the boundaries of the relationship between the competencies of state administrations and local self-government, in practice, often raises questions about their delimitation and ways of regulatory solution. Peculiarities of local self-government in Kyiv city districts are defined in the provisions of the Law on the Capital, which reveal the norms of the Constitution in these legal relations, according to which the issue of organizing district management in cities belongs to city councils. Likewise, it is unregulated by law to lose the particularity of the legal status of the territory of the city. It should be emphasized that the subject of administrative-legal relations is not a certain administrative-territorial entity, but the social group is designated - the territorial community of the city of Kiev, kiyani. Thus, the provisions on the city of Kyiv partially ignore the potential of the territorial community.

The article is devoted to the study of such an important aspect of the activities of the World Russian People's Council (until 1995 it was called the World Russian Council) in the 90-s of the 20-th century as a discussion of national security issues and nuclear disarmament. At that time, a number of political and public figures actively called for the nuclear disarmament of Russia. Founded in 1993, the World Russian Council called for the Russian Federation to maintain a reasonable balance between reducing the arms race and fighting for the resumption of detente in international relations, on the one hand, and maintaining a powerful nuclear component of the armed forces of the country, on the other. The resolutions of the World Russian Council and the World Russian People's Council on the problems of the new concepts formation of foreign policy and national security of Russia in the context of NATO's eastward movement are analyzed in the article. It also shows the relationship between the provisions of the WRNS on security and nuclear weapons issues with Chapter VIII of the «Fundamentals of the Social Concept of the Russian Orthodox Church».

Conventional recommender systems are designed to achieve high prediction accuracy by recommending items expected to be the most relevant and interesting to users. Therefore, they tend to recommend only the most popular items. Studies agree that diversity of recommendations is as important as accuracy because it improves the customer experience by reducing monotony. However, increasing diversity reduces accuracy. Thus, a recommendation algorithm is needed to recommend less popular items while maintaining acceptable accuracy. This work proposes a two-stage collaborative filtering optimization mechanism that obtains a complete and diversified item list. The first stage of the model incorporates multiple interests to optimize neighbor selection. In addition to using conventional collaborative filtering to predict ratings by exploiting available ratings, the proposed model further considers the social relationships of the user. A novel ranking strategy is then used to rearrange the list of top-N items while maintaining accuracy by (1) rearranging the area controlled by the threshold and by (2) maximizing popularity while maintaining an acceptable reduction in accuracy. An extensive experimental evaluation performed in a real-world dataset confirmed that, for a given loss of accuracy, the proposed model achieves higher diversity compared to conventional approaches.

This article proposes a new understanding of the constraints and opportunities that lead intellectuals engaged in different political and social fields to create alternative modes of resistance to domination. The study of the Algerian sociologist Abdelmalek Sayad offers insights into the social conditions of this mode of committed scholarship. On the one hand, this article applies Sayad’s theory of immigration to his transnational intellectual engagements. It establishes how immigrants’ intellectual work are conditioned by their trajectories, both before and after leaving their country, and by the stages of emigration (from playing a role in the society of origin to becoming caught up in the reality of the host society). On the other hand, the article illuminates the constraints and the spaces of possible action intellectuals face while moving across national universes and disparate political and academic fields. Sayad’s marginal position within the academy constrained him to work for the French and Algerian governments and international organizations while he was simultaneously engaged with political dissidents, unionists, writers, and social movements. In tracking Sayad’s roles as an academic, expert and public sociologist, the article uncovers the conditions that grounded improbable alliances between those fields and produced new forms of critique and political action. The article concludes by drawing out some reflections that ‘collective intellectual’ engagements elicit to the sociology of intellectuals.

Previous research shows that the household context is a crucial source of influence on turnout. This article sets out a relational theory of voting in which turnout is dependent on the existence of relational selective consumption benefits. The study provides empirical tests of key elements of the proposed model using household survey data from Great Britain. First, building on expressive theories of voting, it examines the extent to which shared partisan identification enhances turnout. Secondly, extending theories of voting as a social norm, it tests whether the civic norms of citizens’ families or households affect turnout over and above the social norms of the individual. In accordance with expectations of expressive theories of voting, it finds that having a shared party identification with other members of the household increases turnout. It also finds that the civic duty of other household members is important in explaining turnout, even when allowing for respondent’s civic duty.

Purpose The purpose of this paper is to explore potential drivers of high-growth intentions of early-stage entrepreneurs in Greece before and after the onset of the financial crisis of 2008. Design/methodology/approach To this end, the authors use individual-level data retrieved from Global Entrepreneurship Monitor annual surveys (2003-2015). Findings The results show that high-growth intentions of Greek entrepreneurs are driven by different factors in the crisis compared to the non-crisis period. Male entrepreneurs and entrepreneurs with significant work experience seem to be more likely to be engaged in growth-oriented new ventures during the crisis period. The same appears to hold for entrepreneurs who are motivated by an opportunity and also perceive future business opportunities in adverse economic conditions. On the other hand, the educational level and the social contacts of founders with other entrepreneurs are found to drive ambitious Greek entrepreneurship in the years before the crisis, while they were insignificant after the crisis outbreak. Originality/value Based on the concept of ambitious entrepreneurship, this study contributes to the literature by investigating the determinants of entrepreneurial high-growth expectations in the Greek context emphasizing the crisis period in comparison to the pre-crisis years.

Younger Generation

In modern psychological and pedagogical science, the concept of "socialization" is interpreted as the process of development and self-development of a person during the assimilation and reproduction of socio-cultural experience. And, of course, it is very important to ensure the successful socialization of the younger generation. In the modern world, the problem of social development of the younger generation is becoming one of the most urgent. Parents and educators are more concerned than ever about what needs to be done to ensure that a child entering this world becomes confident, happy, intelligent, kind, and successful. In this complex process of becoming a person, a lot depends on how the child adapts to the world of people, whether he will be able to find his place in life and realize his own potentialAt first glance, it seems that the social world of a preschool child is small. This is his family, adults and peers, whom he meets in kindergarten. However, the people around the child enter into a variety of relationships — kinship, friendship, professional and labor, etc. Therefore, even at preschool age, children need to form an idea of the diversity of human relations, tell them about the rules and norms of life in society, and equip them with behavioral models that will help them adequately respond to what is happening in specific life situations. In other words, it is necessary to manage the process of socialization.

The two papers that follow report the results of painstaking epidemiological work on pedestrian accidents involving children. Because these papers relate the age of the child to specific behavior patterns that result in accidents and to specific injury patterns that result from such accidents, they would appear to offer a sound empirical base for the development of a variety of countermeasures, whether such countermeasures are intended to reduce accidents or to limit the severity of the resulting injuries. Unfortunately, however, the ability to generalize such data is extremely limited. A given pattern of child-pedestrian behavior is the result of a highly complex set of variables: the social class and ethnicity of the child, the ecological characteristics of the neighborhood and the broader community, the characteristics of the traffic pattern and the types and density of the vehicles that make it up, the current enforcement policy, climatic conditions, road and highway characteristics, and a host of other conditions that combine and interact in various ways. Consequently, few localities are sufficiently similar to justify the application of data from one to another. The injury patterns described by Ryan, for example, are those produced by Australian vehicles on children walking, playing, and cycling in a specific Australian city. It seems quite unlikely that the injury patterns produced in an American urban environment would resemble those that Ryan reports. Indeed, data from another Australian city might show striking differences. For the same reasons, such data as Read presents cannot be used reliably as a before-and-after measure to assess the effectiveness of a specific countermeasure. Any significant changes in the data after the introduction of a countermeasure might well be attributable not to the countermeasure itself but to changes in traffic patterns, ecology, the weather, or other events which operated to reinforce or counteract the countermeasure in question. The overwhelming obstacle to systematic research in vehicular accidents and on the assessment of countermeasure effectiveness is the investigator's inability to control the numerous variables that affect both the incidence and the consequences of accidents. The present papers, despite their inherently interesting data, are seriously limited by this problem.
