The work described in this paper aims at exploiting the characteristic of a special deformable actuator with rolling membranes to realize a device with defined Remote Center of Compliance (RCC). Starting from theoretical approaches to the definition of the RCC, the authors propose a novel and simple formulation that can be applied to the soft actuator to determine its RCC. The position of the device’s RCC was determined by creating an asymmetry on the geometry of the device along its axis, i.e., by imposing a longitudinal displacement to the piston with respect to the membranes’ rest condition. FEM simulations of the device behavior were carried out and a first formulation describing the placement of the RCC by varying the operating pressure was found. Finally, a comparison of the theoretical model and FEM results is presented, validating the proposed formulation.

Various complex shapes of dielectric electro-active polymer (DEAP) actuator have been promoted for several types of applications. In this study, the actuation and mechanical dynamics characteristics of a new core free flat DEAP soft actuator were investigated. This actuator was developed by Danfoss PolyPower. DC voltage of up to 2000 V was supplied for identifying the actuation characteristics of the actuator and compare with the existing formula. The operational frequency of the actuator was determined by dynamic testing. Then, the soft actuator has been modelled as a uniform bar rigidly fixed at one end and attached to mass at another end. Results from the theoretical model were compared with the experimental results. It was found that the deformation of the current actuator was quadratic proportional to the voltage supplied. It was found that experimental results and theory were not in good agreement for low and high voltage with average percentage error are 104% and 20.7%, respectively. The resonance frequency of the actuator was near 14 Hz. Mass of load added, inhomogeneity and initial tension significantly affected the resonance frequency of the soft actuator. The experimental results were consistent with the theoretical model at zero load. However, due to inhomogeneity, the frequency response function’s plot underlines a poor prediction where the theoretical calculation was far from experimental results as values of load increasing with the average percentage error 15.7%. Hence, it shows the proposed analytical procedure not suitable to provide accurate natural frequency for the DEAP soft actuator.

Current Behavior

In recent years, large food distributors poured considerable effort in the definition of private standards of food safety for their products. Despite these efforts, medium and large retailers have yet to begin advertising to their consumers the adoption of such standards and, in doing so, do not actively pursue a diversification strategy for their products. This behavior seems paradoxical as large retailers would benefit from product differentiation. This article focuses on the role of standards in the coordination of the supply channels and proposes a theoretical model that gives an economic motivation to the current behavior of large retailers. The first objective of this study is to demonstrate how the adoption of standards is a rational choice for large retailers, even in the case in which consumers are not willing to pay for food safety. The reason is that standards can also be used to solve information asymmetry problems and organize the supply chain. Secondly, the theoretical model of contracts suggests that, investments related to the promotion of standards to the consumers, might, under certain conditions, undermine the profits of the large distribution.

The Public Prosecutor's Office in Ukraine plays a major role in the protection of human rights and freedom, of general interests of the society and the country, and in the strengthening of law and order, thus facilitating the establishment and development of the democratic constitutional state. The effectiveness of performing the duties put onto the prosecution of Ukraine is directly dependent on the prosecutor's offices' employees that are empowered to fulfill their professional responsibilities. The legal status of an employee of a prosecutor's office is specified in the Law of Ukraine “On Public Prosecutor’s Office”. Although, some aspects of these employees' work activity are normalised in the general labor law. This expresses the principle of unity and differentiation of the legal regulation of prosecutor's office's employee's labor relations. This article researches theoretical approaches to the definition of the concepts "unity" and "differentiation". The unity of the legal regulation of labor relations is manifested in the legally established equality of all employees. Differentiation is not opposed to the principle of unity, but takes into account the characteristics of different categories of workers and working conditions to ensure equality. The relationship between the general labor law and the special law on the prosecutor's office regarding the adjustment of the labor rights of the employees of Ukraine's prosecutor's offices had been analysed. The key to effective legal regulation of labor rights of employees of the prosecutor's office of Ukraine is compliance with unity and differentiation. It had been determined that the differentiation of the legal regulation of prosecutor's office's employee's labor rights determines the mandatory and priority application of the special legislation norms. In turn, the unity of the legal regulation of prosecutor's office's employee's labor rights determines the subsidiary usage of labor legislation norms in cases of an employee's individual labor rights not being determined in the special law on Public Prosecutor's Office. Unification of labor law norms governing the labor activity of this category of workers will make it possible to achieve an optimal balance of unity and differentiation.

The choice of the article’s topic is conditioned by the necessity to develop happiness management (such as knowledge management, time management, etc.). With considerable attention to the definition of “happiness”, the analysis of recent publications reveals that it is crucial to understand the deep foundations of happiness, create a typology, reveal the basic principles of different types of understanding of happiness, which was chosen as the topic research. Theoretical approaches to the definition of “happiness” are chosen sociology of imagination of G. Durand, the theory of archetypes of C. Jung, and the theory of images and dreams of G. Bachelard. In the context of this system of views, the idea of happiness is the result of a free play of the imagination, which, while being on the path from past to future, is transformed, revealed, comes accurate as a result of previous collective and individual intermediate ideas, and is enriched and concretised by individual people, social groups, individuals. The mythos of happiness across nations and people differs in the way, method, and tools of individuation, the discovery of the Self. The anthropological tract of happiness has an end to its existence. It is determined by the cessation of existence, the life of nations and individuals. The desire to experience pleasure (according to Freud), the desire to rise (according to Durand) are reflexive, which determines the physiological basis of happiness. Representations of happiness determine priorities, coordinate the direction of thinking, actions, reactions to external circumstances, and choose ways to achieve happiness. This is done through the transcendental function (according to Jung) – a psychological function that arises from the connection of the content of the unconscious with the content of consciousness. Achieving happiness allows one to strengthen the subjectivity and reveal their uniqueness, which allows them to identify typological features (archetypes) of behavioural reactions of people based on individual and group ideas about happiness. The authors reveal the basic foundations of such archetypes of happiness as hedonism, eudemonia, “rat racing”, nihilism, subjective well-being.

Aforementioned Study

This article indicated a model for a scientific description of styles of political leadership in Serbia from 1990 to the present, more precisely, pointed the basic elements of concept developed by the author in the study ?The style of political leaders in Serbia in the period 1990-2006? (2010). For the evaluation the author uses analytical tools that include the aforementioned concept, simultaneously indicating correlative theoretical approaches the aforementioned study did not examine, and may be of importance for the research of political elites in Serbia. This contributes the epistemological part of the method, which is registered in the definition of the style of political leadership as a term and the category apparatus that follows - understood from the aspect of the political style: the style in building political power, the style of political communication, the style of building one?s legitimacy, the ideological style, the styles of political language, symbolism and rituals, non-verbal communication and style in expressing patriotism. Starting from the fact that political styles are related to characteristics of political cultures and that it is necessary to make a concept of ideal typical models of styles focused on political subjects, this article marked the styles of political leadership typology related to the specific acting of political leaders in Serbia: authoritarian, republican, realistic, populist, conformist, revolutionary and style of a politician-rebel.
