The purpose of this paper is to make an assessment of the field as it currently stands in order to raise the level of awareness of those directly involved with OD (organizational development). To achieve this, our analysis will demonstrate that an important aspect of OD seems to be excluded from the body of critical literature, i.e., the impact of static core values on ODs ability to change.

The Impact

This study examines the impact of negative workplace gossip (NWG) on employee political acts (PA) and the role of ego depletion (ED) as a mediator. We also examined the indirect impact of NWG on PA through ED controlled by emotional intelligence (EI). A three-wave time-lagged study (paper-pencil based) was performed with 277 employees from various private organisations in Islamabad, Pakistan. The current data were gathered in three phases to reduce common method bias. Study results indicate that NWG positively affects employees’ PA. The authors also found ED as a potential mediator in the association between NWG and PA. In addition, the results also indicate the indirect effect of NWG on targets’ PA via ED is reduced by targets’ EI, with the result that this connection is weak when targets’ EI is high. Because this research is limited to a single region of Pakistan, particularly Islamabad, its findings cannot be comprehensive. Future studies should use a larger sample size to accomplish the same study. Future studies may include more organisations (that is, Public) to conduct a comparative analysis of the public and private sectors. This article, based on the affective events theory (AET), argues that EI should be utilised to mitigate the effects of NWG. Along with our significant and relevant theoretical contributions, we provide novel insights into the body of knowledge on how managers may prevent or minimise such PA. The current study results support all direct and indirect hypothesised connections, with important implications for theory and practice. A review of the existing literature indicates that EI may be associated with a reduction in employees’ ED; however, EI has not been used as a moderator in mitigating the influence of NWG, ED, and PA in the past.

Abstract The goal of this paper is to identify the main criteria based on which e-Learning is used in organizational development with positive impact on business performance. Globalization has led to a multitude of changing markets, including learning and education. While quality production systems are implemented based on imposed standards, the business knowledge of employees varies in each country, mirroring the education system provided locally. The results are individually different knowledge gaps which challenged the learning industry to develop new strategies embedded in e-learning solutions. Major contribution to theory and practice on combining vision and spoken learning is brought by the work of psychologists and professors of education (Allen, 2012; Mayer, 2009; Hattie, 2009). Their innovations offered solutions for easy access to knowledge and implementation methods, as well as the documentation of the inclusion of videos in e-learning modules (Halls, 2012), offering teachers and trainers the possibility to create a live experience to trainees engaged in e-learning programs. This paper is based on data collected internationally and our empirical research undertaken in Romania, which is Europe’s main cluster for various production industries and world’s second for IT. Based on a questionnaire, we interviewed 18 multinational companies which perform parts of their business activities in Romania. Research results show that with the implementation of an effective e-learning strategy a 40-60% cost reduction, a complete measurability of the learning process and a standardized input and outcome of trainings has been achieved. This paper aims to highlight the impact of e-learning applied for business trainings within global developing companies. This study may be applicable to state education and thus could help to reduce the gap between local education and global expectations.

Orientation: Corporate governance adoption and compliance are an issue augmenting in importance recently and have been extended to business enterprises of any size including small and medium enterprises (SMEs).Research purpose: This study seeks to examine the impact of corporate governance adoption on the firm competitiveness and performance of SMEs in Vanderbijlpark.Research design, approach and method: The study employs a cross-sectional research design, which employed quantitative methods. One hundred fifty-two SME owners or managers were selected from Vanderbijlpark in Gauteng, South Africa. The collected data were analysed using a structural equation modelling system by using Smart PLS software.Main findings: The principal findings of this study revealed that the implementation of corporate governance by SMEs significantly and positively affected their competitiveness and performance.Practical and managerial implications: The paper provided practical implications and made some recommendations.Contribution or value-added: This article bridges the gap between theory and practice because it has both an economic and commercial impact in practice. It can be used in influencing public policy, teaching and research (because it contributes to the body of knowledge, particularly regarding SME corporate governance in emerging markets). An important aspect of this article is that it gives a framework for additional similar studies in other locations within emerging markets to test the generalisability of the findings. For teaching purposes, it provides a template for how to assess the link that exists between corporate governance and SME performance. Lastly, the article gives a unique empirical analysis of the relationship that exists between corporate governance compliance and performance of firms in South Africa, and thereby giving a valid contribution to corporate governance literature.

The Relationship

This article succinctly presents general concepts of learning and outlines salient characteristics of learning in the field of music therapy. The relationship between training in music therapy and becoming a music therapist is highlighted along with the place of experiential learning in this context. A description of the transformations perceived as resulting from experiential learning in the author's experience follows, in relation to the self, others and the potential space. The impact of these transformations on the genesis of the Author's practice and conception of music therapy is noted and compared to written accounts of various aspects of music therapy theory and practice. This perspective has implications for music therapy training: becoming a music therapist would then signify becoming a person whose forte lies in the utilization of sound to give freedom to the body and the voice, and sensitivity, intuition and creativity to complement the spoken word and rationality. It invites the therapist to do justice to the term "therapy" embedded in "music therapy" and, accordingly, to give weight to the experiential dimension in music therapy training programs.

This research examines the rise of Islamic populism in Indonesia and understands it as an instrument to clear a new pathway for populism movement into popular culture. Ummi magazine is one of the religious media used to be political vehicles of stablishing constituencies, especially for the Tarbiyah movement in the Soeharto era to the current tendency to popularize the Tarbiyah identity as a new lifestyle. Historically, The Tarbiyah movement in Indonesia is a social and political movement among Indonesian Muslimah students, especially activists in the Suharto period. Muslim middle class entrepreneurs launched a campaign of ‘economic jihad.  This research uses a qualitative approach by interpreting and studying the data contained in Ummi Magazine. Media studies were carried out in the January 2017 to 2018 editions. The data obtained were described and associated with the magazine's transformation as an ideological medium and Muslim women's lifestyle today. The result shows that the magazine's transformation from ideology magazine to lifestyle magazine can influence readers because there are more new readers. Whether Ummi as a media for da'wah and a women's magazine, it is still perceived by the readers to apply ideological coercion or simply provide an alternative lifestyle or consumption where religious independence is the main characteristic of the magazine. We argue that Islamic populism is mainly   a medium for coercion ideology to gain tracks to power, while the poor remain as ‘floating mass’, and entrapped in many so-called 'empowerment' projects. Populism can be interpreted as a communication style in which a group of politicians considers themselves to represent the people’s interests contrasted with elite interests. Nevertheless, the populism approach is gaining momentum. Abdullah, I. (1996). Tubuh, Kesehatan, dan Struktur yang Melemahkan Wanita. Kumpulan Makalah Seminar Bulanan.

Background. One of the most important questions in the acting profession is how to educate the psychophysical apparatus of the actor, what it consists of, what exercises will be useful and will be able to develop the necessary psychophysical qualities. Therefore, the theatrical teachers often turn to the sciences, which study the human, to be able to rely not only on the personal experience and on theoretical works of famous theatrical figures. Therefore, K. Stanislavsky creating theory of art turned to experimental psychology, the theory of conditioned reflexes by I. Pavlov. K. Stanislavsky sought to substantiate scientifically his system, to analyze creativity based on “brain physiology”, to study objectively higher nervous (mental) activity. One of the basic elements of the actor’s psychophysics is imagination, which remains by far one of the least studied. Moreover, the first studies of the “imagination” in such science as neuroscience began only in the second half of the XX century. Today, it is important to pay attention to the discoveries that take place in the related sciences in order to be able to understand deeper how a particular exercise affects the psychophysics of a future actor. There is a small amount of contemporary work devoted to the theoretical substantiation of the development of the psychophysical qualities of the actor. Among them the writings by famous theater educators Uta Hagen (“Play as Life”) and Ivana Chubbuk (“Chubbuk’s Actor Technique”) are, which consider the concept “imagination” in relation to other elements of actor psychotechnics, as one of the tools and ways of creating the role. The American actor and a teacher Gavin Levy has created an interesting book “275 Acting Games: Connected” presenting various exercises connected with developing of imagination. Professor of Acting at the University of California Bella Merlin in her work “Acting: Theory and Practice” proposes to develop imagination through a variety of games and improvisation also. Attempts to comprehensive study of actor training, the impact of exercise on the imagination and psychophysics of the actor as a whole are described in the works of M. Alexandrovskaya, S. Gippius, N. Rozhdestvenskaya, V. Petrov, and L. Gracheva, whose experimental results was used in this study, The objective of this paper is to consider the concept of “imagination” in the complex and interaction with other elements of actor psychophysics, using the latest scientific discoveries about human. A complex methodology was used in the work: analysis and synthesis methods that allow to explore a category such as “imagination”, separately and in conjunction with the elements of actor psychophysics; methods of systematization and generalization – to determine the key theoretical provisions of the study in the context of understanding the pedagogical experience of modern domestic and foreign theater schools; method of historical and cultural analysis – in the course of consideration of works on the theory of theater. Results. The concept of “imagination” in acting training is used quite often, but there is no specific answer to the question – whether imagination trains or not. Professor of Russian State Institute of Performing Arts Larissa Gracheva conducted an experiment to help answer this question. Students were asked to recall and relive in their imagination the acute emotional situation that was in the life of each participant in the experiment. A total of 30 student actors and 20 economics and theater students were involved. This experiment affirms the influence of special acting exercises on developing the imagination, because 95 % of participant-actors demonstrated body physical reactions. This concept is considered the paper in conjunction with other elements of actor psychotechnics, such as “visions” (after K. Stanislavskiy), affective and emotional memory, reaching truthful expressiveness on stage and muscular freedom. The chain of interaction between these elements is proposed and their interdependence is justified. The experiment answered the question of how imagination is dependent on “visions” and affective memory, what kind of exercises the future actors can train their imagination. Links has been established between imagination and muscular freedom. Recent discoveries of neuroscience have been used to answer the question of what is going on with the brain, when human being imagines something. Overall, the paper summarizes the current state of knowledge of the selected topic by discussing the findings presented in recent research papers that create an understanding of the theme for the reader. Conclusions. Training of “awakening the imagination” is a complex psychophysical process that can be developed only in combination with other elements of actor psychotechnics. Such complex approach will allow the actor to shape a completely harmonious personality. Imagination is based on visions that form and emerge from each person’s long-term memory. For each actor, these internal images will be unique. This proves that the use of imagination (substitution effect and affective memory) is quite personal and unique process. This approach causes an impression of truth of drama action and induces a strong emotional response. In turn, emotional reaction is first a muscular reaction of the body. Therefore, in acting training it is important to make exercises so as to harmoniously develop the psyche and physics of the actor using in plastic exercises imagination and vice versa, the physics reactions for the developing of imagery thinking.

The purpose of this study is to examine the impact of Shariah governance and corporate governance (CG) on the risk management practices (RMPs) of local Islamic banks and foreign Islamic banks operating in Malaysia. The Shariah governance comprises the Shariah review (SR) and Shariah audit (SA) variables. The study also evaluates the level of RMPs, CG, SR, and SA between these two type of banks. With the aid of SPSS version 20, the items for RMPs, CG, SR, and SA were subjected to principal component analysis (PCA). From the PCA, one component or factor was extracted each for the CG, SR, and RMPs while another two factors were extracted for the SA. Primary data was collected using a self-administered survey questionnaire. The questionnaire covers four aspects ; CG, SR, SA, and RMPs. The data received from the 300 usable questionnaires were subjected to correlation and regression analyses as well as an independent t-test. The result of correlation analysis shows that all the four variables have large positive correlations with each other indicating a strong and significant relationship between them. From the regression analysis undertaken, CG, SR, and SA together explained 52.3 percent of the RMPs and CG emerged as the most influential variable that impacts the RMPs. The independent t-test carried out shows that there were significant differences in the CG and SA between the local and foreign Islamic banks. However, there were no significant differences between the two types of the bank in relation to SR and RMPs. The study has contributed to the body of knowledge and is beneficial to academicians, industry players, regulators, and other stakeholders.

Summary. The disbalanced feeding and the uneven distribution of micro- and macroelements in the environment leads to a trace element, in particular hypomelanosis. To accelerate the growth and preservation of young farm animals include in the diet of various biological additives and drugs, which include selenium. For stimulation of weight gain in the livestock industry, as well as for the prevention and treatment of pathological processes in addition to micro - and macrouse amino acids, primarily methionine. The aim of this work was to study the influence of composition of DAFS-25+Polizon on morpho-biochemical parameters of blood and functional state of the liver in fattening bulls of black-motley breed in the conditions of the Republic of Bashkortostan. Experiments using were conducted on bull-calves of black-motley breed of the properties in the properties age from 6 to 15 months. The first experimental group during the experiment was additionally given the composition of DAFS-25+Polizon at a dose of 2 mg/kg, the animals of the control group received a standard diet. To assess the impact of the composition DAFS-25+Polizon on metabolism cattle studied morphological and biochemical indicators of blood and conducted histological examination of the liver. It is established that the use of the composition of DAFS-25+Polizon at a dose of 2 mg/kg increases the number of erythrocytes and hemoglobin in the experimental group and reduces the amount of white blood cells. The serum content of total protein, phosphorus and calcium increases in the group of experimental animals. Microscopic examination of the liver revealed no changes in the structure of the organ and hepatocytes in the experimental group, whereas in the control group hemodynamic disorders and dystrophic changes in liver cells were observed. Thus, the use of the composition DAFS-25+Polizon at a dose of 2 mg/kg of live weight in fattening bulls black-and-white breed contributes to the increase of redox processes in the body, stimulation of metabolism, prevent the development of liver disorders of cellular mechanisms of metabolism, optimizes the structure of the liver, which generally provides higher productivity.

Introduction. The impact on the body of such factors of the production environment as coal-rock dust and fluorine compounds leads to certain shift s in strict indicators of homeostasis at the system level. Maintaining the relative constancy of the internal environment of the body is provided by the functional consistency of all organs and systems, the leading of which is the liver. Organ repair plays a crucial role in restoring the structure of genetic material and maintaining normal cell viability. When this mechanism is damaged, the compensatory capabilities of the organ are disrupted, homeostasis is disrupted at the cellular and organizational levels, and the development of the main pathological processes is noted.The aim of the study is to compare the morphological mechanisms of maintaining structural homeostasis of the liver in the dynamics of the impact on the body of coal-rock dust and sodium fluoride.Materials and methods. Experimental studies were conducted on adult white male laboratory rats. Features of morphological mechanisms for maintaining structural homeostasis of the liver in the dynamics of exposure to coal-rock dust and sodium fluoride were studied on experimental models of pneumoconiosis and fluoride intoxication. For histological examination in experimental animals, liver sampling was performed after 1, 3, 6, 9, 12 weeks of the experiment.Results. The specificity of morphological changes in the liver depending on the harmful production factor was revealed. It is shown that chronic exposure to coal-rock dust and sodium fluoride is characterized by the development of similar morphological changes in the liver and its vessels from the predominance of the initial compensatory-adaptive to pronounced violations of the stromal and parenchymal components. Long-term inhalation of coal-rock dust at 1–3 weeks of seeding triggers adaptive mechanisms in the liver in the form of increased functional activity of cells, formation of double-core hepatocytes, activation of immunocompetent cells and endotheliocytes, ensuring the preservation of the parenchyma and the general morphostructure of the organ until the 12th week of the experiment. Exposure to sodium fluoride leads to early disruption of liver compensatory mechanisms and the development of dystrophic changes in the parenchyma with the formation of necrosis foci as early as the 6th week of the experiment.Conclusions. The study of mechanisms for compensating the liver structure in conditions of long-term exposure to coal-rock dust and sodium fluoride, as well as processes that indicate their failure, and the timing of their occurrence, is of theoretical and practical importance for developing recommendations for the timely prevention and correction of pathological conditions developing in employees of the aluminum and coal industry.The authors declare no conflict of interests.
