IThe tendency of business entities to cope with the challenges of the environment in which they operate is determined by the state and development of a complex system of evaluation indicators describing the condition and performance of the company and their time dynamics. They serve to objectively measure the extent to which the individual economic operator meets the conditions by which to be assigned to the group of successful business agents. In traditional retail trade, the most significant indicators for business evaluation are: gross (profit) margin, operating margin, turnover of inventories, gross return on investment in inventories, gross profit per employee, etc. The paper examines the key economic performance indicators of the three leading retail chains in the retail sales of fast moving consumer goods (FMCG) in Bulgaria.

The classical numerical output, or indicator, from assessments of the long-term safety of geological disposal systems for high-level radioactive waste is the individual effective dose rate. This indicator is an estimate of the possible individual health detriment and it is commonly compared to regulatory limits for assessing the safety of other nuclear activities as well, such as medical and industrial activities. As a safety indicator, the individual dose rate provides an estimate of the overall safety of the disposal system. However, because of the time frames involved in safety assessments of geological disposal systems, the need arises of complementary safety indicators that could be less affected by uncertainties like those associated with future human behaviour or the effects of climate change on the biosphere and the aquifers. Such alternative safety indicators can be, for example, radionuclide concentrations in the groundwater or fluxes to the biosphere due to a repository. Safety indicators only tell how globally safe a disposal system is. For confidence building, performance indicators can be used in addition to tell how the system works. In particular, performance indicators such as fluxes, activities or activity concentrations of selected radionuclides can show how the different components of the system fulfil their safety functions and contribute to the overall safety. The SPIN project of the European Commission assessed the usefulness of seven safety indicators and fourteen performance indicators by testing them in four actual assessments of disposal systems in granite formations. In this paper, indicators calculated from an assessment of the disposal of spent fuel in the poorly indurated Boom Clay formation are presented. Conclusions from the SPIN project that hold for repositories in clays are highlighted, as well as results that illustrate differences between the granite and clay disposal options. Finally, various performance and safety indicators are combined into a logical sequence to comprehensively present, and explain, the results of a safety assessment.

The quality of the software can be measured by its return on investment. Factors which may affect the return on investment (ROI) is the tangible factors (such as the cost) dan intangible factors (such as the impact of software to the users or stakeholder). The factor of the software itself are assessed through reviewing, testing, process audit, and performance of software. This paper discusses the consideration of return on investment (ROI) assessment criteria derived from the software and its users. These criteria indicate that the approach may support a rational consideration of all relevant criteria when evaluating software, and shows examples of actual return on investment models. Conducted an analysis of the assessment criteria that affect the return on investment if these criteria have a disproportionate effort that resulted in a return on investment of a software decreased.

Heat pumps are the key technology to decarbonise thermal processes by upgrading industrial surplus heat using renewable electricity. Existing insight-based integration methods refer to the idealised Grand Composite Curve requiring the full exploitation of heat recovery potential but leave the question of how to deal with technical or economic limitations unanswered. In this work, a novel Heat Pump Bridge Analysis (HPBA) is introduced for practically targeting technical and economic heat pump potential by applying Coefficient of Performance curves into the Modified Energy Transfer Diagram (METD). Removing cross-Pinch violations and operating heat exchangers at minimum approach temperatures by combined application of Bridge Analysis increases the heat recovery rate and reduce the temperature lift to be pumped at the same time. The insight-based METD allows the individual matching of heat surpluses and deficits of individual streams with the capabilities and performance of different market-available heat pump concepts. For an illustrative example, the presented modifications based on HPBA increase the economically viable share of the technical heat pump potential from 61% to 79%.

Government Reforms

In this study the authors analyze the effects of e-government reforms that began in mid-90ies by confronting the promises which these reforms made to government performance in the period before and after the reforms took place. The authors use fiscal and performance indicators of the Slovenian government and courts to argue that e-government did not yield any notable effects on the state performance. Finally, the authors analyze the reasons why e-government technology cannot be regarded as sustainable and suggest a different approach towards researching how to sustainably improve governance for generations to come.

Purpose The purpose of this paper is to explore how entrepreneurship traditions evolve in diaspora. Design/methodology/approach A qualitative multiple case study examining the role of diaspora embeddedness, extended family, ethno-religious-, cultural- and social ties and relevant structures shaping diaspora entrepreneurship. Findings The authors found that social ties and diaspora embeddedness create dynamism fostering entrepreneurial identity as a part of the Bukharian culture, and as a preferred career option in the context of Bukharian Jews in diaspora. Diasporic family businesses are products of culture and tradition that migrate to new locations with families and communities, not as disconnected business entities. Research limitations/implications The ways in which families nurture a highly entrepreneurial culture that transfers across generations and contexts are context-specific and not per se generalizable to other diasporas. Practical implications Diasporans often continue their traditions and become again entrepreneurs after their settlement, or they may generate hybrid, circular solutions that allow them to employ their competences in the new contexts or connecting various contexts. This calls for transnational entrepreneurship-policymaking. Social implications Time changes diasporas. A long-term commitment to the business environment evolves and reduces the mobility of the individual diasporan; typically the children of these migrants become more integrated and develop divergent career paths. Hence, their plans are not necessarily including family entrepreneurship creating a challenge for continuation of the original culture of entrepreneurship. Originality/value Despite a notable tradition in Jewish studies, there is limited research on Jewish entrepreneurial diaspora and its contemporary entrepreneurial identity and tradition. Furthermore, the population of Bukharian Jews is an unknown and under-explored highly entrepreneurial group that may offer instrumental views to larger diasporic audiences being concerned about maintaining notions of ethnic heritage and identity.

Due to their inherent noise challenge and potential for significant reductions in fuel burn, counter-rotating propfans (CRPs) are currently being investigated as potential alternatives to high-bypass turbofan engines. This paper introduces an integrated noise and performance assessment methodology for advanced propfan powered aircraft configurations. The approach is based on first principles and combines a coupled aircraft and propulsion system mission and performance analysis tool with 3D unsteady, full-wheel CRP computational fluid dynamics computations and aeroacoustic simulations. Special emphasis is put on computing CRP noise due to interaction tones. The method is capable of dealing with parametric studies and exploring noise reduction technologies. An aircraft performance, weight and balance, and mission analysis was first conducted on a candidate CRP powered aircraft configuration. Guided by data available in the literature, a detailed aerodynamic design of a pusher CRP was carried out. Full-wheel unsteady 3D Reynolds-averaged Navier-Stokes (RANS) simulations were then used to determine the time varying blade surface pressures and unsteady flow features necessary to define the acoustic source terms. A frequency domain approach based on Goldstein’s formulation of the acoustic analogy for moving media and Hanson’s single rotor noise method was extended to counter-rotating configurations. The far field noise predictions were compared to measured data of a similar CRP configuration and demonstrated good agreement between the computed and measured interaction tones. The underlying noise mechanisms have previously been described in literature but, to the authors’ knowledge, this is the first time that the individual contributions of front-rotor wake interaction, aft-rotor upstream influence, hub-endwall secondary flows, and front-rotor tip-vortices to interaction tone noise are dissected and quantified. Based on this investigation, the CRP was redesigned for reduced noise incorporating a clipped rear-rotor and increased rotor-rotor spacing to reduce upstream influence, tip-vortex, and wake interaction effects. Maintaining the thrust and propulsive efficiency at takeoff conditions, the noise was calculated for both designs. At the interaction tone frequencies, the redesigned CRP demonstrated an average reduction of 7.25 dB in mean sound pressure level computed over the forward and aft polar angle arcs. On the engine/aircraft system level, the redesigned CRP demonstrated a reduction of 9.2 dB in effective perceived noise (EPNdB) and 8.6 EPNdB at the Federal Aviation Regulations (FAR) 36 flyover and sideline observer locations, respectively. The results suggest that advanced open rotor designs can possibly meet Stage 4 noise requirements.

The article analyses various approaches to assessing the PR activities of commercial organizations and public authorities. The author concludes that there is no comprehensive methodology for analyzing and evaluating the effectiveness of PR activities. This indicates the relevance and the need to develop a special methodology to identify relevant and potential sources for the formation and development of a complex image and reputation characteristics of public authorities with which citizens of the Russian Federation could operate. The basis of the proposed theory is the materials of works on communication by G. Lasswell (model of mass communication, pentad). The method is a system of evaluation parameters, performance indicators, and analytical tools for each structural component of such activities, as well as an algorithm for their analysis and evaluation. When developing this methodology, we try to take into account the maximum number of criteria and performance indicators, but in practice, it is not always possible. To increase the effectiveness of the methodology, the author conducts the structuring of the pentad, which allows to distinguish the main processes of PR activity of a public authority. The assessment of each component of the pentad is a separate study in which we can identify the relevant PR activity processes that require adjustment.
