Since technological lifecycles do not always match hardware/software (HW/SW) lifecycles, obsolescence becomes a major issue in system lifecycle management as it can cause premature and unscheduled replacement of HW/SW subsystems. The purpose of this paper is to report a dynamic model to predict the obsolescence dates for HW/SW subsystems.

The dynamic model estimates obsolescence dates for HW/SW subsystems based on graph theory concept. The model depicts the stages of subsystem obsolescence through transmittances composed of probability and time-distribution elements. The model predicts probability and mean time to obsolescence for line replaceable units (LRUs) over the lifetime of the system. An illustrative example in signaling systems used in a train control system was used to demonstrate the application of this model.

Generally, the short timespan for HW/SW subsystems, which are periodically replaced with newer technologies, results in the development of new product lines by suppliers while they try to support legacy systems for a reasonable period of time. Obsolescence of HW/SW subsystems increases operation and maintenance costs as legacy systems are typically more expensive to maintain. The costs can be reduced by an optimum time to obsolescence derived from the model.

This research adds to the body of knowledge on asset management and maintenance strategy. This paper may be of particular interest to reliability, maintainability and availability practitioners and project managers.

The originality of this paper lies in developing a graph-based model that predicts probability and mean time to obsolescence for LRUs over the lifetime of the system.

This paper aims to discuss current work and further steps of the psychological hotline launched by the National Psychological Association of Ukraine (NPA), along with a call for action to mental health professionals worldwide.

This paper describes the training and support of the NPA’s hotline staff as well as reflections on the hotline’s work from June 2022 to April 2023.

With broad international support, the NPA’s psychological hotline currently operates in 21 countries providing psychological assistance and referrals to other service providers within Ukraine and abroad. The authors propose further steps of its work, including international collaboration.

Providing citizens of Ukraine with broad public access to evidence-based remote psychological support through NPA’s hotlines is a high priority considering the war’s negative impact on mental health diverse and the limited capacity of the state mental health system.

The focus of this article is on non‐coercive means (i.e. reward and persuasion) for pursuing international conflicts. The article uses case studies of six Middle East peace efforts to analyse the conditions which affect the utilisation and contribution of non‐coercive means. It looks at the factors that account for the limited use of non‐coercive means by adversaries in trying to induce the enemy to yield what was desired and at factors affecting the success of those efforts that are made.

Gluten is a triggering factor for gluten-related disorders. However, the present market provides expensive, less varied and poor nutritional products. Therefore, this study aims to develop gluten-free muffins and improve their nutritional profile, as well as evaluate the physical, chemical and sensorial aspects of them.

A combination of pearl millet, buckwheat and amaranth was used to formulate gluten-free muffin using central composite rotatable design of response surface methodology for optimization of selected parameters (hydroxypropyl methyl cellulose [HPMC], baking temperature and baking time). The optimized muffins were incorporated with Moringa leaves powder. Finally, the final products were compared with the wheat muffins.

The optimization range of selected variables was 1% HPMC, 170°C baking temperature and 30.33 min baking time with a desirability function of 0.75. The incorporation of 5% Moringa leaves powder enhanced the nutritional profile of gluten-free muffins – increased protein (38%), fiber (208%), iron (224%) and calcium (25%) values. However, the overall acceptability reduced due to decrease in flavor and odor.

Nonetheless, the ease of accessibility of these convenience gluten-free muffins as well as the nutritional density can help the food research and nutritionists to bridge the gap in current gluten-free market. This puts focus on the use of underutilized crops such as millets and buckwheat which are nutritionally dense.

The increased use of government imposed countertrade (mandated countertrade) by developing nations (LDCs) to meet their economic goals has been of particular concern to international executives. Frequently, countertrade can be mandated by LDCs on transactions even with their long‐time trading partners. Firms therefore need to anticipate actions of their LDC trading partners to be competitive in the global market place. Inadequate preparation can result in repercussions such as exclusion from specific deals, to exclusion from a particular country‐market.

As the use of countertrade increases and countertrade research proliferates, it is necessary to integrate the knowledge to document what has been done and identify gaps for future research. Proposes Bagozzi′s exchange framework as a model for integrating research and identifying situational contingencies, characteristics of social actors and third parties, and social influence between actors as the determinants of exchange. Managerial implications are also identified.

Over the past two decades, the Organisation for Economic Co-operation and Development (OECD) has become an influential actor in the education sector. This has been accomplished, partly, by the administration of the Programme for International Student Assessment (PISA) since 2000. Overall, PISA is intended to inform the public, parents, teachers, and those who run education systems of the status of education in their country. Research shows that policymakers draw on PISA results when they launch and design education reforms. To date, however, we know very little about whether PISA is successfully informing the general public, which is the main sponsor and benefactor of PISA. Using public opinion surveys from the United States and Israel, this chapter examines knowledge and perception of PISA. Recent reports suggest that both countries are in the middle ranks of all countries participating in PISA, with the United States being in the middle ranks of OECD countries and Israel being in the lower ranks of this group. Findings from public opinion surveys reveal three interesting patterns. First, in both countries, the public tend to underestimate how well 15-year olds perform on international standardized tests. Second, college graduates are more likely than those with less education to underestimate the performance of teens on international standardized tests. Third, although the public seems to be misinformed about PISA results, we find considerable public support for PISA and international standardized tests more generally. Implications of the findings for policy and future research in the field of international and comparative education are discussed.

The purpose of this paper is to examine current performance management practices, identify potential areas of improvement and recommend appropriate interventions. Developing economies continue to intrigue in light of the promise they hold for future growth markets. Existing studies tend to focus on macro-economic factors and to concentrate on a few regions. Few studies have looked at the lesser developed Middle-Eastern regions, such as Palestine. This study seeks to address that deficit; it examines firm-level factors relevant to the competitive performance of enterprises in the Palestinian stone and marble industry, one of the most important industries in the region.

The study utilizes a mixed-methods exploratory qualitative and quantitative approach that probes operational and strategic performance factors. Interviews and insights derived from a survey-based research data from 45 respondents representing a sampling of 36 enterprises form the basis of the analysis.

Findings suggest that the majority of performance measures employed by the firms investigated rely primarily on traditional financial indicators. Although some progressive metrics including those targeting measures of productivity and process efficiency are being adopted by firms in the sector, measures that focus on long-term strategic growth promoters such as innovation and organizational learning are largely not yet employed.

The paper concludes with recommendations for how firms competing in such environments might enhance and improve their performance management.
