Based on an analytical narrative, and utilizing macroeconomic and new institutional economic theory, this exposition studies the Bulgarian economy during the decades after 1989. The three decades are placed in the context of the century-and-a-half-long Bulgarian development and convergence dynamic. They are then presented in terms of clearly defined sub-periods, and each sub-period is analyzed in detail. The analysis for each period focuses on three sets of issues: macroeconomic developments, microeconomic developments, and institutional changes. The exposition ends by applying the insights from the analysis to the question of whether the state of the economy in Bulgaria as of 2019 gives grounds for pessimism (Bulgaria will continue the cycles of unsuccessful convergence) or for optimism (Bulgaria will achieve an unprecedented degree of convergence in the coming decades). The answer is that at present both expectations can be supported by sets of serious arguments.

An analysis of the degree of convergence of theoretical pictures of the dynamics of the autoionization event He(23S)-D2(v" = 0) -> [He...D2+(v')] + e is presented for a number of batches of Monte Carlo calculations differing in the number of the trajectories run. The treatment of the dynamics consists in 2D classical trajectory calculations based on static characteristics which include a quantum mechanical treatment of the perturbed D2(v" = 0) and D2+(v') vibrational motion. The vibrational populations are dynamical averages over the local widths of the He(23S)-D2(v" = 0) state with respect to autoionization to D2+(...He) in its v'th vibrational level and the Penning electron energies are related to the local differences between the energies of the corresponding perturbed D2(v" = 0)(...He*) and D2+(v')(...He) vibrational states. Special attention is paid to the connection between the requirements on the degree of convergence of the classical trajectory picture of the event and the purpose of the calculations. Information is obtained regarding a scale of the trajectory calculations required for physically sensible applications of the model to an interpretation of different type of experiments on the system: total ionization cross section measurements, Penning ionization electron spectra, subsequent 3D classical trajectory calculations of branching ratios of the products of the postionization collision process, and interpretation of electron ion coincidence measurements of the product branching ratios for individual vibrational levels of the nascent Penning ion.

This study investigated the technological developments in the shale petroleum industry by analyzing patent data using a network of technological indices. The technological developments were promoted by the beginning of the shale industry, and after the first five years, it showed a more complex development pattern with the convergence of critical technologies. This paper described progress in the shale petroleum technologies as changes in relatedness networks of technological components. The relatedness represents degree of convergence between technological components, and betweenness centrality of network represents priority of technological components. In the results, the progress of the critical technologies such as directional drilling, increasing permeability, and smart systems, were actively carried out from 2012 to 2016. Especially, unconverged technology of increasing permeability and the converged technology of directional drilling and smart system has been intensively developed. Some technological components of the critical technologies are more significant in the form of converged technology.

Perceptions of authenticity (or, inauthenticity) have been shown to affect people’s judgments and behavior across a wide variety of domains. However, there is still ambiguity about how the concept should be defined. This is attributable, at least in part, to a growing list of different “kinds of authenticity” with little discussion of the potential overlaps between them. The goal of this paper is to reduce these various notions of authenticity into a more manageable set of constructs. Building on the work of Newman and Smith (2016a), three broad kinds of authenticity are proposed: Historical, Categorical, and Values authenticity. Two studies then examine the extent to which people’s conceptions of authenticity naturally segment into these three types. Specifically, Study 1 asks participants about the various ways in which they might assess authenticity, whereas Study 2 examines individual differences in sensitivity to different kinds of inauthenticity. The results from both studies indicate a striking degree of convergence in support of these three broad dimensions. Moreover, different populations appear to be differentially concerned about these various ways of evaluating authenticity. The implications of this framework for existing and future work in this area are discussed.

Military institutions have been considered “gendered organizations” because gender is persistently related therein to the production and allocation of material and symbolic resources. Western states’ militaries consistently, even if unevenly, display three basic traits through which gendering occurs: the existence of structural divisions of labor and power along gender lines, organizational culture and ideology based on a distinction between masculinity and femininity, and patterns of interaction and identity formation that reflect these structural and ideological constraints. Although women’s representation has been growing, and women have been accessing new roles, positions, and occupations in unprecedented numbers, their participation is statistically limited and substantially uneven. Notable differences between countries also exist. At a macro-sociological level, factors that explain these differences relate to the degree of convergence between armed forces and society, external political pressures, military organizational format, and the level of gender equality in society at large. From a micro-sociological perspective, research shows that, because of their minority situation and less valued status in an organization normatively defined as masculine, women still have to face the negative consequences of tokenism: performance pressures, social isolation, and role encapsulation. However, this research also highlights two important conclusions. The first is that there is significant variation in individual and organizational responses depending on context; the second, that conditions for successful gender integration depend on specific combinations of structural, cultural, and policy dimensions: the existence or absence of institutional support, changes in the composition of groups, increase in the number of women, type of work, occupational status, level of shared experience, changing values of younger cohorts, and quality of leadership. The Women, Peace and Security agenda, evolving from the approval of United Nations Security Council Resolution 1325 in 2000, has become the major reference framework to evaluate progress in this respect at both domestic and international levels. Despite the existence of an extremely robust set of norms, policies, and instruments, and the recognition of their transformative potential, results have been considered to lag behind expectations. Improving implementation and enhancing gender integration in the military will require context-sensitive and knowledge-driven policies, the reframing of an essentialist discourse linking women’s participation in international missions to female stereotypical characteristics, and greater congruence between national policies and the international agenda.
