Progress in catalysis depends on a full understanding of the role of the individual components of catalytic materials. Crystallographic studies offer insight into crystal structure, which enables the rational selection of reagents and better planning of the syntheses of novel materials and catalysts. In this paper we have studied the process of the oxidation of hydrocarbons and terpenes with oxygen from the air. Processes of this type are important in so-called "Green Chemistry." Their application can reduce the amount of environmentally harmful pollutants formed through conventional oxidation based on nitric acid. While investigating the catalytic activity of peroxo- and polymolybdates(VI) in the oxidation of cycloalkanes, we found a number of intriguing relationships. To explain them, we designed, synthesized and solved the crystal structures of the family of new peroxomolybdates, tri-, octa- and pentamolybdates of amines. Both single crystal and polycrystalline materials were investigated using laboratory as well as synchrotron radiation. Next, we used these compounds as catalysts in certain interesting for industry processes (e.g. oxidation of cyclic hydrocarbons). We have concluded that: – The activity of peroxocompounds is enhanced by the coordination of N-oxide groups to Mo atoms. – The activity of anionic polymeric trimolybdates decreases when `surface of polymeric fiber' is blocked by cations. – The anionic layers of pentamolybdates are separated by cations of variable size. The distance between layers plays a role similar to that of the size of channels in zeolites. Summary: Peroxomolybdates and polyoxomolybdates show great prospects for new industrial uses (besides cracking and desulfurization).

In the decade following the passage of the Federal Securities Laws of 1933 and 1934, the reform of accounting and auditing practices directed authority for selection of accounting principles and auditing procedures away from the discretion of the individual accountant and auditor. Instead, a self-regulatory peer driven process to establish general acceptance for a more limited set of principles and procedures was being initiated. Two events which occurred in 1938 indelibly affected this process, the SEC's decision to issue Accounting Series Release No. 4, which empowered non-governmental entities as potential sources of authoritative support, and the McKesson & Robbins fraud which called into question the value of the independent audit and the role of external auditing at the very time a momentum had been established for self-regulation by the nascent and recently reunified accounting profession. The contributions of Samuel J. Broad in both the initiatives for self-regulation of accounting principles and of auditing procedures is examined in this paper. Further, several examples of Broad's rhetorical technique of employing analogous reasoning to facilitate dissemination of complex economic and accounting issues are examined.

RNA viruses play a significant role in the current high losses of pollinators. Although many studies have focused on the epidemiology of western honey bee (Apis mellifera) viruses at the colony level, the dynamics of virus infection within colonies remains poorly explored. In this study, the two main variants of the ubiquitous honey bee virus DWV as well as three major honey bee viruses (SBV, ABPV and BQCV) were analyzed from Varroa-destructor-parasitized pupae. More precisely, RT-qPCR was used to quantify and compare virus genome copies across honey bee pupae at the individual and subfamily levels (i.e., patrilines, sharing the same mother queen but with different drones as fathers). Additionally, virus genome copies were compared in cells parasitized by reproducing and non-reproducing mite foundresses to assess the role of this vector. Only DWV was detected in the samples, and the two variants of this virus significantly differed when comparing the sampling period, colonies and patrilines. Moreover, DWV-A and DWV-B exhibited different infection patterns, reflecting contrasting dynamics. Altogether, these results provide new insight into honey bee diseases and stress the need for more studies about the mechanisms of intra-colonial disease variation in social insects.

Most researchers of socialization processes agree that the primary socialization carried out in the family is crucial. The phenomenon of the family was considered in terms of psychological, sociological, anthropological, philosophical, biological and cultural approaches. Now the question of surrogacy is being studied in terms of the psychology of the life path of the individual; as manifestations of the meaning of life, will, responsibility; as a world of the subjective, where is always something more. Many scientists pay attention to the methodology, organization, functioning of foster families; the problems of lifestyle of orphan children in general, and in particular – in a professionally foster family. Scientists have considered the motivation of the adopted child into the family and some socio-psychological characteristics of parents. However, there are almost no studies of some individual-typological features that dysfunctionally affect family relationships, although these features may be the reason for the denial of the family's ability to be a substitute. The relevance of the study is due to the need of supplement the structural and semantic components of the psychological diagnosis of potential parents in foster families. The empirical study was conducted on the basis of the Odessa Regional Center for Social Services for Families, Children and Youth, a territorial division of the Odessa Regional State Administration. In testing took a part about 30 applicants for foster parents. With the help of Individual-typological questionnaire LM Sobchyk (ITO) there was created an average statistical portrait of candidates for the role of parents in foster families. They are characterized by a high level of extraversion (48.6%); average level of rigidity (82.9%), aggression (54.3%), anxiety (82.9%), introversion (71.5%), lability (74.3%), sensitivity (62.9%), spontaneity (60%). All these qualities positively characterize all members of the sample and confirm their reliability as potential parents in foster families. These conclusions can be used by psychologists in the selection of candidates for the role of foster parents in foster families, as well as in psychological counseling.

Thymos (or thumos), cognate with Indo-European words meaning “smoke,” is one of a number of terms in Greek which associate psychological activity with air and breath. In the Homeric poems, thymos is one of a family of terms associated with internal psychological process of thought, emotion, volition, and motivation. Though the range of the term’s applications in Homer is wide, that in itself gives us a sense of the unity of cognitive, affective, and desiderative processes in Homeric psychology. No post-Homeric author can rival that range, but something of the richness of the Homeric conception of thymos as an interrelated set of motivations re-emerges in Plato’s conception of the tripartite soul in the Republic and the Phaedrus. Plato’s thymos represents a pared-down model of human agency typified by one central desire or aim in life but also exhibiting whatever further capacities of persons are necessary to enable it to pursue that aim in interaction with the other elements of the personality. As in Homer, the metaphorical agency of Plato’s thymos does not detract from the notion of the individual as the real centre of agency. Plato’s conception of thymos, in turn, is a fundamental point of reference for Aristotle’s treatment of thymos as a type of desire (orexis). Though Aristotle tends more generally to use the term as a synonym for orgē (anger), there are also traces of older associations between thymos and qualities such as assertiveness and goodwill towards others. Elsewhere, thymos tends to mean “heart” or “mind” (as aspects of mental functioning), “spirit,” “inclination,” or “anger.” A selection of these uses is surveyed, but the article overall concentrates on Homer, Plato, and Aristotle, where the role of thymos is of a different order of importance.

The nature nurture issue has been an important debate in all aspects of the individual development. According to Jensen’s heritability ratio, hereditary has an impeccable influence in the development process. Based on these, dermatoglyphics has been used in the present case study in order to observe the innate potential of an individual, to give parents an insight into their child’s hidden potential and to groom them effectively. The present case study is confined to the acquiring methods and unique quotients of the subject. The findings of the study revealed the unique quotients of the subject and the best suitable acquisition method for the subject.  Aim/Purpose: To test the methods of learning and unique quotients of the subject with the help of Dermatoglyphics Multiple Intelligence Test DMIT.  Int. J. Soc. Sci. Manage. Vol-2, issue-3: 301-303 DOI: http://dx.doi.org/10.3126/ijssm.v2i3.12651

The dynamic variability of the modern world determines not only the need to adapt but also the ability to preserve and maintain the values of separate culture. Over the centuries, family is considered to be one of the core values. Family interaction with the society is undeniable. The family is the foundation of any society and the future of the state. Today's new socio-economic situation has an impact on the emotional atmosphere, quality and relationships within the family. Criminological research in family relationships is a complex problem, its environment and circumstances are an important factor in the individual's socialization. The role of the family is equally important both in the process of proper behavioural shaping and in the production of directed behaviour. The article provides an insight into the content of the studies of family criminology.The aim of the article is to describe the criminological framework of family relations based on special literature, research and practice showing the framework of family criminology. Theoretical guidelines, special literature, views and opinions of Latvian and foreign specialists have been analysed in order to assess the criminological aspects of the phenomenon.The author concludes that the knowledge of family criminology is useful, effective, concrete and practically feasible for the criminological studies of the family institute. This approach has a multi-sectoral nature.

Facilitated communication (FC) is an expressive communication strategy that involves the selection of targets on a letter display or keyboard by an individual who receives some physical support, typically from another person (known as the facilitator). Because physical assistance is needed for communication to occur, the question has arisen as to whether the facilitator or the individual who is facilitated is responsible for authoring messages. This investigation was initiated to determine whether messages expressed via FC by a 38-year-old man who was nonspeaking and mentally retarded were produced by this individual or by his facilitator. In order to investigate the source of communication, three procedures were designed, two of a visual and one of an auditory nature. Results revealed that the source of the communication in this context was, without exception, the facilitator. These findings suggest the importance of determining the source of communication expressed through facilitated communication.

The traditional way of providing feedback to students after tests or assignments is labour-intensive. This paper explains the concepts and techniques used by the author to build computer-based applications that analyse students’ answers and generate individualised, detailed and constructive feedback. The paper explains how the data gathered from a student’s answers can be combined with other knowledge about the subject matter being taught, and the specific test questions, to create computerised routines that evaluate the individual student’s performance. This information can be presented in ways that help students to assess their progress, both in relation to their acquired knowledge in specified areas of study, and with regard to their ability to exercise relevant skills. In this way, appropriate feedback can be provided to large numbers of students quickly and efficiently. The same techniques can be used to provide information to the instructor about the performance of the group as a whole, with a degree of detail and accuracy that exceeds the impressions usually gained through traditional marking. The paper also explains the role of the subject instructor in designing and creating feedback-generating applications. The methodologies described provide insight into the details of the process and are a useful basis for further experimentation and development.
