Mastering high‐density optical disks, like the Blu‐ray™ disk, requires new equipment design. Active magnetic bearing technology seem well suitable for this purpose, but challenges arise in obtaining the required extreme accuracy. Creating a very low mechanical coupling between the system and the external world is the potential solution to this challenge pursued in this paper. Design considerations on actuators, amplifiers, sensors and overall design are discussed and the system performance is predicted using an error‐budgeting estimation. This prediction indicates the feasibility of the concept, while the first prototype has been assembled and is being tested.

This study aims at evaluating the technical efficiency (TE) of healthcare systems in the Arab region and exploring the key factors that affect the efficiency performance.

The study applies a two-stage Data Envelopment Analysis (DEA) approach to a sample of 20 Arab countries. In the first stage, a DEA model is used to calculate the TE scores of the examined healthcare systems in 2019 and 2010, following both the output and input orientations of efficiency. In the second stage, a censored Tobit model is estimated to investigate the determinants of healthcare efficiency.

DEA results of 2019 indicate that achievable efficiency gains of the Arab countries range from 0.4% to 16% under the output and input orientations, respectively. Six countries are efficient under both orientations. Although the average efficiency scores of the Arab countries have deteriorated between 2010 and 2019, Djibouti and Sudan had the greatest efficiency improvements between the two years. Bahrain, Mauritania, Morocco and Qatar proved to be efficient in 2010 and 2019 under the two orientations of efficiency and according to the two DEA specifications followed. The Tobit model reveals that corruption and government health expenditure tend to have an adverse impact on healthcare efficiency.

The author evaluates healthcare efficiency and healthcare's efficiency determinants in the Arab countries. Regardless Arab countries' diversity, these countries are facing common health challenges, including diminishing role of governments in healthcare financing; increased out-of-pocket healthcare spending; poor healthcare outputs and prevalence of health inequities resulting from weak governance institutions. Comparing the efficiency of healthcare systems between 2010 and 2019 gives insights on the potential impact of the Arab spring uprisings on healthcare efficiency. Moreover, examining the determinants of healthcare efficiency allows for better understanding of how to improve the efficiency of healthcare systems in the region.

Ever since Mark Weiser coined the term “ubiquitous computing” (ubicomp) in 1988, there has been a general interest in proposing various solutions that would support his vision. However, attacks targeting devices and services of a ubicomp environment have demonstrated not only different privacy issues, but also a risk of endangering user’s life (e.g. by modifying medical sensor readings). Thus, the aim of this paper is to provide a comprehensive overview of security challenges of ubicomp environments and the corresponding countermeasures proposed over the past decade.

The results of this paper are based on a literature review method originally used in evidence-based medicine called systematic literature review (SLR), which identifies, filters, classifies and summarizes the findings.

Starting from the bibliometric results that clearly show an increasing interest in the topic of ubicomp security worldwide, the findings reveal specific types of attacks and vulnerabilities that have motivated the research over the past decade. This review describes most commonly proposed countermeasures – context-aware access control and authentication mechanisms, cryptographic protocols that account for device’s resource constraints, privacy-preserving mechanisms, and trust mechanisms for wireless ad hoc and sensor networks.

To the best of our knowledge, this is the first SLR on security challenges in ubicomp. The findings should serve as a reference to an extensive list of scientific contributions, as well as a guiding point for the researchers’ novel to the security research in ubicomp.

The purpose of this study is to address the main reasons that limit Jordanian women from undertaking expatriation, based on the assumption that Arab women’s opportunities for international engagement may be compromised by local cultural and institutional issues.

A cross-sectoral survey with 60 Jordanian expatriates (30 women and 20 men) located in EU countries and the UK is used to better explore Eastern women perceptions.

Company’s resistance, a lack of support mechanisms, safety in the destination country and family commitments play a major role in hindering Jordanian women opportunities to be assigned abroad, echoing the commonly recognized barriers identified in previous research. Additionally, the culture of the home country and prejudice toward foreigners act as an additional barrier for women professional development.

The main limitation of this study lies in the data collection instrument, that is, the survey. Larger samples are needed to extend these results. The second limitation is that the potential effects of gender differences cannot be examined because the number of men in the sample was small.

The findings bring evidence that could be used by organizations to understand the barriers Jordanian expatriate women face and take informed action to tackle them. Meanwhile, more research on Middle Eastern female roles and views is needed to reduce stereotyping against them. Similarly, regional studies can be an opportunity for future development to identify the impact of the regional context.

This research highlights the intertwining of religious and cultural values in influencing Arabic women’s experience in international assignments and thus, would enhance readers’ understanding of women’s career progression in a new context.

This research shows that socio-cultural and political realities need more space in discussions about expatriation. Specifically, the expatriation literature needs more scrutiny and problematizing of the lived experiences of women expatriates from the Global South.

This paper aims to investigate the relationship between global economic fluctuations and human development through four transmission channels (foreign direct investment (FDI), official development aid (ODA), remittances and export earnings) in Egypt as an open developing economy, in the period 1990–2015.

The paper uses a vector autoregressive model, which implies examining the impulse response functions and variance decompositions.

The results indicate that human development is negatively affected by global economic fluctuations through the four channels, namely, ODA, FDI, export earnings and remittances. In addition, the most effective transmission channels are FDI in the short run and export earnings in the long run.

While a large body of literature addresses the direct impact of business cycles and economic shocks on human development, only some studies focus on the indirect impact. The contribution is to identify the indirect impact of global economic fluctuations on human development in a developing economy, considering four transmission channels and to determine the most important of these channels. Moreover, using the human development index is an addition in this paper as most previous literature depends on other human development indicators such as children’s health, employment and schooling.

One of the main theories regarding the relationship between government expenditure and gross domestic product (GDP) is Wagner’s law. This law was developed in the late-19th century by Adolph Wagner (1835–1917), a prominent German economist, and depicts that an increase in government expenditure is a feature often associated with progressive states. This paper aims to examine the validity of Wagner’s law in Egypt for 1960–2018. The relationship between real government expenditure and real GDP is tested using three versions of Wagner’s law.

To test the validity of Wagner in Egypt, law time-series analysis is used. The methodology used in this paper is: unit-root tests for stationarity, Johansen cointegration approach, error-correction model and Granger causality.

The results provide strong evidence of long-term relationship between GDP and government expenditure. Moreover, the causal relationship is found to be bi-directional. Hence, this study provides support for Wagner’s law in the examined context.

It should be noted, however, that there are some limitations to this study. For instance, in this paper, the government’s size was measured through government consumption expenditure rather than government expenditure due to data availability, which does not fully capture the government size. Moreover, the data available was limited and does not fully cover the earliest stages of industrialization and urbanization for Egypt. Furthermore, although time-series analysis provides a more contextualized results and conclusions, the obtained conclusions suffer from their limited generalizability.

This paper aims to specifically make a contribution to the empirical literature for Wagner’s law, by testing the Egyptian data using time-series econometric techniques for the longest time period examined so far, which is 1960–2018.

In the context of asian cities, streets define the diversity and vibrancy of public spaces despite facing a constant threat of losing the spaces to motorized vehicles and large-scale development. The social life of streets is eroded as a result of new developments that are exclusive and privately regulated. This paper discusses the attributes that influence the sociability of shopping streets based on the street users' assessment. A questionnaire survey was conducted involving 332 respondents in four main shopping streets in the Kuala lumpur city centre, Malaysia. Identification of the sociability attributes using analytic network Process (anP) was applied to determine the sociability factors based on the order of priority. The study found that users tended to participate in social activities while visiting the shopping streets. However, their social behaviour indicated that the actual engagement in optional and informal activities was not regular. Perceived safety and spatial accessibility mainly influenced the users' level of engagement with the streets' activities. To retain streets as inclusive social spaces, urban designers could prioritise mixed-land uses, positive pedestrian experience and good accessibility in boosting sociability of urban places.

This paper aims to explore the applied context of grocery retail pricing practice to understand how pricing executives approach “regular price” decision-making (as opposed to promotional pricing). The study seeks to inductively develop a model of regular price decision-making in grocery retailing.

The research uses an inductive methodology involving interviews with pricing executives working for grocery retailers that account for approximately 85 per cent of the UK, and 64 per cent of USA, grocery market retail sales. The approach is appropriate given the underdeveloped research insights into regular pricing within food retailers.

It is found that regular pricing is undertaken with little sophistication, typically, on the basis of simple, inflexible rules that result in conflicting goals. A typology of three pricing roles was identified, although all share an underdeveloped understanding of the effects of price changes on customer demand and the implications of competitor reactions. These contexts, causes and conditions lead to a range of consequences; notably, a degree of pricing inertia, “customer-less” pricing and “enforced symbiosis” – coping outcomes. Taken together, a theory of “passivity” pricing is identified.

The research presents a contribution to new knowledge in the field of retail marketing by developing theory in retail pricing. In contrast to much extant research on grocery pricing, this paper accesses the insights and opinions of the pricing executives themselves. It exposes the realities of regular price decision-making across two developed retail markets and offers managerial insights.

This article explores the role of history and historical memory in the formation of early Zionist/Israeli national security doctrine. To that end, it makes three moves. First, it explores a series of public addresses made by Zalman Rubashov (Shazar) in 1942–1943. A key public intellectual in the Jewish community of preindependent Palestine (the Yishuv), Rubashov means to help his listeners make sense of, and respond collectively to, the unfolding destruction of European Jewry. Second, it draws cautious parallels between those public intellectual pronouncements and the postwar work of Friedrich Meinecke, a prominent German historian and public intellectual and a sometime teacher of Rubashov. In both cases, I suggest, history does more than make sense of a moment of political transition: It seeks to reframe the self-understandings of citizens and their collective political relations. Third, drawing on a recent memoir by Noam Chayut, a prominent Israeli antioccupation activist, I explore how those self-understandings can be lost when the historical claims upon which they are predicated lose their sense of immediacy, naturalness, or coherence.

Roots of global Terrorism are in ‘failed’ states carved out of multiracial empires after World Wars I and II in name of ‘national self‐determination’. Both sides in the Cold War competed to exploit the process of disintegration with armed and covert interventions. In effect, they were colluding at the expense of the ‘liberated’ peoples. The ‘Vietnam Trauma’ prevented effective action against the resulting terrorist buildup and blowback until 9/11. As those vultures come home to roost, the war broadens to en vision overdue but coercive reforms to the postwar system of nation states, first in the Middle East. Mirages of Vietnam blur the vision; can the sole Superpower finish the job before fiscal and/or imperial overstretch implode it?
