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.

Fault Proneness

Nowadays, modern applications are developed using components written in different programming languages and technologies. The cost benefits of reuse and the advantages of each programming language are two main incentives behind the proliferation of such systems. However, as the number of languages increases, so do the challenges related to the development and maintenance of these systems. In such situations, developers may introduce design smells (i.e., anti-patterns and code smells) which are symptoms of poor design and implementation choices. Design smells are defined as poor design and coding choices that can negatively impact the quality of a software program despite satisfying functional requirements. Studies on mono-language systems suggest that the presence of design smells may indicate a higher risk of future bugs and affects code comprehension, thus making systems harder to maintain. However, the impact of multi-language design smells on software quality such as fault-proneness is yet to be investigated. In this article, we present an approach to detect multi-language design smells in the context of JNI systems. We then investigate the prevalence of those design smells and their impacts on fault-proneness. Specifically, we detect 15 design smells in 98 releases of 9 open-source JNI projects. Our results show that the design smells are prevalent in the selected projects and persist throughout the releases of the systems. We observe that, in the analyzed systems, 33.95% of the files involving communications between Java and C/C++ contain occurrences of multi-language design smells. Some kinds of smells are more prevalent than others, e.g., Unused Parameters , Too Much Scattering , and Unused Method Declaration . Our results suggest that files with multi-language design smells can often be more associated with bugs than files without these smells, and that specific smells are more correlated to fault-proneness than others. From analyzing fault-inducing commit messages, we also extracted activities that are more likely to introduce bugs in smelly files. We believe that our findings are important for practitioners as it can help them prioritize design smells during the maintenance of multi-language systems.

Dominant Paradigm

Why are some democratic governments more successful than others? What impact do various political institutions have on the quality of governance? This paper develops and tests a new theory of democratic governance. This theory, which we label centripetalism, stands in contrast to the dominant paradigm of decentralism. The centripetal theory of governance argues that democratic institutions work best when they are able to reconcile the twin goals of centralized authority and broad inclusion. At the constitutional level, our theory argues that unitary, parliamentary, and list-PR systems (as opposed to decentralized federal, presidential, and nonproportional ones) help promote both authority and inclusion, and therefore better governance outcomes. We test the theory by examining the impact of centripetalism on eight indicators of governance that range across the areas of state capacity, economic policy and performance, and human development. Results are consistent with the theory and robust to a variety of specifications.

Исследованы прочностные и физико-механические свойства оболочки рапса с точки зрения ее разрушения и удаления. Установлено, что наиболее рациональным является двухстадийный способ обрушивания: 1-я стадия – на вальцовых мельницах, 2-я – на центробежной обрушивающей машине. Определены параметры центробежной обрушивающей машины для обеспечения минимальной необходимой линейной скорости 10,81 м/с: угол наклона отбойной пластины (90 ± 2)°, частота вращения барабана (2400 ± 150) об/мин. Установлено, что правильно подобранные условия и угол, под которым происходит удар, позволяют значительно снизить количество не до конца обрушенного семени и содержание расколотого ядра. При этом при свободном ударе об отбойную пластину под углом, отличным от 88–91°, или подаче недостаточно равномерного потока семян значительно увеличивается содержание необрушенных семян. На разрушение 1 кг семян необходимо затратить 58,45 Дж. Таким образом, по расчетным данным, для семян рапса диаметром 1,5 мм частота вращения барабана должна находиться в диапазоне от 2221 до 2565 об/мин при ударе семени под углом 90°. Диаметр семян рапса, выращиваемого в Сибирском регионе, составляет от 0,8 до 1,8 мм. Установлено, что подсушивание семян рапса в течение 30–40 с при температуре 100°С позволяет увеличить эффективность разрушения оболочки до полного ее отделения от ядра рапса. Представленные результаты позволяют повысить качество очистки семян рапса от оболочки и улучшить качественные характеристики получаемого масла, облегчить последующие технологические процессы получения пищевого масла, снизить затраты на рафинацию и дезодорацию на 2%. The strength and physico-mechanical properties of the shell of rapeseed in terms of its destruction and removal are investigated. It is established that the most rational is a two-stage method of seed hulling: the 1st stage – on roller mills, the 2nd – on a centrifugal hulling machine. The parameters of the centrifugal hulling machine to provide the minimum required linear speed of 10,81 m/s are defined: the angle of inclination of the turnback plate (90 ± 2)°, the rotational speed of drum (2400 ± 150) RPM. It is established that the correctly selected conditions and the angle at which the impact occurs, can significantly reduce the amount is not completely hulling seed and the substance of the split nucleus. At the same time, with a free impact on the turnback plate at an angle different from 88–91°, or the supply of an insufficiently uniform flow of seeds, the content is not completely hulling seed increases significantly. On hulling of 1 kg of seeds it is necessary to spend 58,45 J. Thus, according to the calculated data, for rape seeds with a diameter of 1,5 mm, the rotational speed of drum should be in the range from 2221 to 2565 RPM when the seed is struck at an angle of 90°. The diameter of rapeseed grown in the Siberian region ranges from 0,8 to 1,8 mm. It was found that drying of rapeseed for 30–40 s at a temperature of 100°C, can increase the efficiency of destruction of the shell to its complete separation from the core of rapeseed. The presented results make it possible to improve the quality of cleaning of rape seeds from the shell and improve the quality characteristics of the obtained oil, facilitate the subsequent technological processes of obtaining edible oil, reduce the cost of refining and deodorization by 2%.

Abstract Background Eating disorders (ED) can reduce quality of life by limiting participation and performance in social and occupational roles, including paid or unpaid work. The association between ED pathologies and work participation and performance must be well understood to strengthen vocational rehabilitation programmes and prevent occupational disruptions in the ED population. The aims of this study are: (1) to examine the degree of association between ED pathologies and work participation and performance in 15-year-olds and older; (2) to highlight the specific ED symptoms that are most correlated with changes in work performance and participation; (3) to compile the most common metrics and assessments used to measure work participation and performance with ED. Methods Medline, Embase, CINAHL, Web of Science, PsycINFO, and Cochrane Library will be searched for observational and experimental studies that meet the following criteria: (1) a clinical sample of typical or atypical ED; (2) paid or unpaid employment or training; (3) an association between ED pathologies and work participation or performance. Unpublished data will also be examined. Title and abstract, and full-text screening will be conducted in duplicate. Risk of bias and quality of evidence assessments will be completed. A random-effect meta-analysis will be performed. Discussion This synthesis can clarify knowledge and gaps around the impact of ED on work functioning, thereby allowing better evaluation, improvements and development of current workplace assessments, interventions, and policies. Trial registration The registration number for this systematic review on PROSPERO is CRD42021255055.

Immersive Technologies

The permeability of all spheres of both economic activity and human life with digital technologies encourages the search for new marketing ideas necessary for the implementation of the product (goods, works and services).  Today's consumer has become more demanding both to the product itself and to the ways of presenting it.  Immersive technologies are becoming one of the tools that contribute to the formation of competitive advantages, especially the organization of business in the field of entertainment, as one of the areas of additional income in the field of hotel and restaurant services and marketing activities of enterprises.  Digital transformation leads to the search for new initiatives that will be a tool to meet customer needs and a way to reach wider market segments.  The process of digitalization must first be integrated into the economy of the whole state and the enterprise as a whole, and in all processes of production of goods, works and services.  Digital-transformation of domestic enterprises will help to obtain additional competitive advantages both in the domestic market and in the international market.  The formation of competitive advantages is associated not only with the maximum involvement of digital technologies in business.  It is important to choose such technologies that will be most effective in the implementation of a particular type of enterprise, under certain conditions and in a particular environment. The expediency of using immersive technologies as a marketing tool is undeniable.  However, in addition to tools, immersive technologies are important as a means of education, a separate milestone in the field of entertainment, a means of psychological influence and more.  That is, the impact of this tool on the level of competitiveness of the enterprise in the environment of the demanding consumer is manifested: in the form of reducing the cost of attracting the client; active covert promotion through their use; improving the quality of the presented product (goods, works, services); ensuring the elasticity of the enterprise to the needs and requirements of consumers; the transition of the enterprise to an innovative type of development and active digitalization.

Test Result

Procuring and managing diagnostic services, such as laboratory medicine, is generally based on cost and activity. Improving productivity of laboratory services therefore tends to focus on reducing the cost per test. However, this approach fails to recognise the impact of the test result on the other stakeholders involved in delivering care to the patient across the care pathway. Any assessment of the return on investment from a diagnostic service therefore needs to be undertaken together with a value proposition established for the service. This will enable the clinical, process and economic impact for all stakeholders to be assessed, which can then be used to develop an implementation plan that ensures the expectations of all stakeholders can be addressed.

Abstract Objective Retrospective and prospective memory deficits are associated with lower quality of life (QoL); however, there are no validated measures that comprehensively and directly assess the impact of memory problems on QoL. The Survey of Memory-Related Quality of Life (SMRQoL) was developed as a 30-item questionnaire to measure memory-related QoL. Method Both HIV+ (n = 195) and HIV− (n = 146) participants completed the SMRQoL, a neurocognitive research battery, and validated self-report questionnaires of memory, QoL, and mood. Participants were recruited into younger (age ≤ 40 years) and older (age ≥ 50 years) groups per the parent study design. Results The SMRQoL had a unidimensional factor structure and demonstrated measurement invariance across the HIV+ and HIV− participants. Analyses of 111 clinically stable participants (e.g., persons with no incident or remitting central nervous system disorders) who returned for a 14-month follow-up visit indicated that the SMRQoL had adequate test–retest stability. There was a significant interaction of age and HIV status on the SMRQoL, such that older HIV+ participants reported the lowest memory-related QoL. SMRQoL scores were associated with validated measures of mental and physical QoL, self-reported memory and cognitive symptoms, and performance-based memory and executive functions. Conclusions The SMRQoL shows evidence of reliability and validity as a measure of memory-related QoL that can be used to assess the impact of memory problems on everyday life, but future work is needed to demonstrate the measure’s incremental value in the context of diagnosis and treatment.
