The Impact

The issue of interoperability among multiple autonomous databases has attracted a lot of attention from researchers in these years. The past research on this issue can be roughly divided into two main categories: the tightly-integrated approach that integrate databases by building an integrated schema and the loosely-integrated approach that achieves interoperability by using a multidatabase language. Most of the past efforts focused on the issues in the first approach. The problem with the first approach is, however, that it lacks a convenient representation of the integrated schema at the system level and a sound mathematical basis for data manipulation in a multidatabase system. In this paper, we propose to use hyperrelations as a powerful and succinct model for the global level representation of heterogeneous database schemas. A hyperrelation has the structure of a relation, but its contents are the schemas of the semantically equivalent local relations in the databases. With this representation, the metadata of the global database, local databases and the data of these databases are all representable by using the structure of a relation. The impact of such a representation is that all the elegant features of relational systems can be easily extended to multidatabase systems. A hyperrelational algebra is designed accordingly. This algebra is performed at the multidatabase systems (MDBS) level such that query transformation and optimization is supported on a sound mathematical basis. The major contributions of this paper include: (1) Local relations of various schemas (even though they retain information of the same semantics) can be systematically mapped to hyperrelations. As the structure of a hyperrelation is similar to that of a relation, data manipulation and management tasks (such as design of the global query language and the view mechanism) are greatly facilitated. (2) The hyperrelational algebra provides a sound basis for query transformation and optimization in a MDBS.

Based on historical-genetic and comparative research methods, the article reveals the determinants of formation and development of the city commemorative culture. This issue is relevant because of the increasing influence of the memory of the past on modern sociocultural processes. The scientific novelty of the article lies in the study of poorly studied issues of the impact of commemorative culture on the development of culture in general; the opportunities of regulating the nature and distribution of memorial forms; the factors determining the formation of the city commemorative culture in the context of the historical and sociocultural dynamics of applicable societies of the civilizations of the past and present. The article uses an integrated approach, which determines the interdisciplinary nature of scientific research, allowing analyzing the aspects of the origin, interpretation of the features of the history and existence of monuments in different cultures. There are provided examples of commemoration practices in the post-Soviet countries, including the Republic of Belarus. The article concludes that the content of commemorative culture is determined primarily by religious traditions and state priorities. The creation of monuments and places of memory is used as an agitation and manipulative resource making an emotional impact; as an ideological tool shaping the perception of history in accordance with the state ideology. Commemorative practices take on special significance during the formation of nations, influencing the subject’s identification with the nation, and the awareness of national solidity. In this case, the monument represents a universal form of embodying and conveying the national idea.

The Impact

Burnout is a prolonged response to chronic emotional and interpersonal stressors on the job, and is defined by the three dimensions of exhaustion, cynicism, and inefficacy. Job burn-out is a debilitating psychological condition, which has serious repercussions for an individual's personal health as also on the organizational effectiveness. The past 25 years of research has established the complexity of the construct, and has placed the individual stress experience within a larger organizational context of people�s relation to their work. As a holistic science concerned with all aspects of human functioning, yogic science provides a unifying framework by which stress can be understood and eliminated. Yoga involves a systematic method by which we can begin to expand our awareness of the processes which lead to stress and thus gain control over them. Yoga way of life has direct relevance to address the issue of stress and burnout. While several studies in the past have acknowledged this aspect and discussed various ways by which Yoga can address this aspect, till date very little effort has gone into empirically assessing the impact of Yoga way of life. The main contribution of this paper is to fill this gap. This study hypothesizes that managers who learn and adopt the Yoga way of life will be able to reduce their job burnout better than the others who engage in other things to improve their physical and mental progress. An experiment was conducted to collect data and test the hypothesis in a manufacturing unit. The results show that adoption of the Yoga way of life can significantly reduce the job burnout of managers. The Yoga way of life is an integrated approach to the changing physical, mental, vital and emotional personality of an individual. It is aimed at making managers more evolved individuals with better understanding of their job situation in the overall context of life. Through a rigorous literature review and understanding of the science of Yoga as given in our scriptures, the paper also provides an explanation of the mechanism of how this happens. Among many suggested coping skills for stress, yoga happens to be fitting in the best, mainly because of its ability to change positively the individual responses to stress stimuli. However, in order to get benefit of Yoga in its entirety, one has to adopt Yoga as a technique of life management. The authors motivate the HR managers in organizations to explore ways of implementing the Yoga way of life as it promises to address the issue of stress at a fundamental level.

The Impact

Purpose – The purpose of this paper is to provide a research synthesis of substantive findings drawn from studies of educational leadership and management in Hong Kong between 1995 and 2014. The goal of the research synthesis was to identify and elaborate on key trends identified by scholars who studied educational leadership in Hong Kong over the past two decades. The synthesis drew upon on relevant articles published in eight “core international journals” specializing in educational leadership and management. Design/methodology/approach – The study first identifies a clearly delimited body of relevant literature comprised of empirical, non-empirical and review/synthesis types of studies in a total of 161 published research articles from the eight journals. Information concerning the nature of the studies as well as substantive findings was extracted from each of the articles. The findings were then initially coded in preparation for data analysis. Synthesis of substantive findings was accomplished by cross-article comparative mapping aimed at identifying key themes in the literature. Findings within four of the most robust themes were then synthesized and reported. Findings – The synthesis highlights the challenges faced in Hong Kong’s efforts to reshape its education in a multi-faceted quest for quality education in the twenty-first century. A variety of inter-related issues emerged as policymakers and education administrators sought to implement a full plate of imported globally recognized education reforms. Analysis of the research from this period yielded four robust themes: “leadership development,” “leadership for learning,” “organizational change,” “multi-level performance focus.” The findings also further highlight the impact of “education policy borrowing” on system-level efforts to revamp the structural conditions in which school leaders operate and reshape managerial, as well as teaching and learning processes in schools. Research limitations/implications – Although the scope of the sources included in the review are highly representative of the “Hong Kong literature” of the past two decades, the authors note that it was not an “exhaustive” review of all potential sources. Originality/value – Prior research by Hallinger and Bryant (2013b) had identified Hong Kong as having produced the largest volume of literature in educational leadership and management in Asia. This paper represents the first systematic review of research findings that emerged in the recent educational leadership literature produced in Hong Kong. Therefore, although the authors make no claims of generalizability to other parts of Asia or even to China as a whole, the paper offers insight into how global trends have reshaped the practice of educational leadership in one East Asian society.

The Impact

A major application of potentiometric dyes has been the multisite optical recording of electrical activity in excitable systems. After being championed by L.B. Cohen and his colleagues for the past 20 years, the impact of this technology is rapidly being felt and is spreading to an increasing number of neuroscience laboratories. A second class of experiments involves using dyes to image membrane potential distributions in single cells by digital imaging microscopy - a major focus of this lab. These studies usually do not require the temporal resolution of multisite optical recording, being primarily focussed on slow cell biological processes, and therefore can achieve much higher spatial resolution. We have developed 2 methods for quantitative imaging of membrane potential. One method uses dual wavelength imaging of membrane-staining dyes and the other uses quantitative 3D imaging of a fluorescent lipophilic cation; the dyes used in each case were synthesized for this purpose in this laboratory.

The burden of caregivers has been intensively researched for the past 30 years and has resulted in a multitude of individual findings. This review illustrates the significance of the hypothetical construct of perceived burden for the further development and design of the homecare situation. Following explanations regarding the term informal caregiver, we derive the construct burden from its conceptual association with the transactional stress model of Lazarus and Folkman. Once the extent and characteristics of burden have been set forth, we then present the impact of perceived burden as the care situation. The question of predictors of burden will lead into the last section from which implications can be derived for homecare and relief of caregivers.

Under the term “Hilfe zur Arbeit” (aid for work) the federal law of social welfare subsumes all kinds of labour disciplining instruments. First, the paper shows the historical connection of welfare and labour disciplining mechanisms in the context of different periods within capitalist development. In a second step, against the background of historical experiences, we will analyse the trends of “Hilfe zur Arbeit” during the past two decades. It will be shown that by the rise of unemployment, the impact of labour disciplining aspects of “Hilfe zur Arbeit” has increased both on the federal and on the municipal level. For this reason the leverage of the liberal paradigm would take place even in the core of social rights.

The Impact

Polyaminopolyamide-epichlorohydrin (PAE) resins are the predominant commercial products used to manufacture wet-strengthened paper products for grades requiring wet-strength permanence. Since their development in the late 1950s, the first generation (G1) resins have proven to be one of the most cost-effective technologies available to provide wet strength to paper. Throughout the past three decades, regulatory directives and sustainability initiatives from various organizations have driven the development of cleaner and safer PAE resins and paper products. Early efforts in this area focused on improving worker safety and reducing the impact of PAE resins on the environment. These efforts led to the development of resins containing significantly reduced levels of 1,3-dichloro-2-propanol (1,3-DCP) and 3-monochloropropane-1,2-diol (3-MCPD), potentially carcinogenic byproducts formed during the manufacturing process of PAE resins. As the levels of these byproducts decreased, the environmental, health, and safety (EH&S) profile of PAE resins and paper products improved. Recent initiatives from major retailers are focusing on product ingredient transparency and quality, thus encouraging the development of safer product formulations while maintaining performance. PAE resin research over the past 20 years has been directed toward regulatory requirements to improve consumer safety and minimize exposure to potentially carcinogenic materials found in various paper products. One of the best known regulatory requirements is the recommendations of the German Federal Institute for Risk Assessment (BfR), which defines the levels of 1,3-DCP and 3-MCPD that can be extracted by water from various food contact grades of paper. These criteria led to the development of third generation (G3) products that contain very low levels of 1,3-DCP (typically <10 parts per million in the as-received/delivered resin). This paper outlines the PAE resin chemical contributors to adsorbable organic halogens and 3-MCPD in paper and provides recommendations for the use of each PAE resin product generation (G1, G1.5, G2, G2.5, and G3).

Subject. The article addresses the specifics of shadow economic activities in reformed Russia in the context of systemic transformations. Objectives. We focus on determining the role of shadow economy in the reproductive process, identifying and understanding the specifics of underground economic activity of the Russian economy. Methods. The study rests on general scientific methods (scientific abstraction, unity of historical and logical, analysis and synthesis, induction and deduction, comparison and analogy) and special methods of cognition (monetary methods). We employ the systems and integrated approach. The official statistics, regulations, works of leading researchers on shadow economy expansion, resources of reference and legal systems like Garant and ConsultantPlus serve as the study's information base. Results. We present a retrospective rapid analysis of the extent of shadow economic activity in the domestic economy, establishing the relationships with the processes that take place at different stages of the country's development. We also reveal the specifics of shadow economy relations in Russia, factors that play a key role in expansion for a particular period, a shift to another form of shadow economy. The study characterizes the current period of development, assesses the impact of external shocks on shadow economy expansion. Conclusions. The current period is characterized by the digitization of shadow relations, the shift of corruption to the upper echelons of power, the continued outflow of capital abroad, and increased penalties for underground activities.

This book, hereinafter referred to as the Guide, has been developed for those social analysts (e.g., anthropologists, sociologists, and human geographers) who have had little or no practical experience in applying their knowledge as development practitioners. In the past, development projects would be analysed from a narrow financial and economic perspective. But with the evolution of thinking on development, this narrow financial and economic aspect has now been broadened to include the impact on society as the very meaning of development has now come to symbolise social change. Thus, development is not restricted only to plans and figures; the human environment in its entirety is now considered for analysis while designing and implementing development projects.
