The purpose of this study is to reveal the dynamics of house prices and sales in spatial and temporal dimensions across British regions.

This paper incorporates two empirical approaches to describe the behaviour of property prices across British regions. The models are applied to two different data sets. The first empirical approach is to apply the price diffusion model proposed by Holly et al. (2011) to the UK house price index data set. The second empirical approach is to apply a bivariate global vector autoregression model without a time trend to house prices and transaction volumes retrieved from the nationwide building society.

Identifying shocks to London house prices in the GVAR model, based on the generalized impulse response functions framework, I find some heterogeneity in responses to house price changes; for example, South East England responds stronger than the remaining provincial regions. The main pattern detected in responses and characteristic for each region is the fairly rapid fading of the shock. The spatial-temporal diffusion model demonstrates the presence of a ripple effect: a shock emanating from London is dispersed contemporaneously and spatially to other regions, affecting prices in nondominant regions with a delay.

The main contribution of this work is the betterment in understanding how house price changes move across regions and time within a UK context.

A cross-domain intelligent software-defined network (SDN) routing method based on a proposed multiagent deep reinforcement learning (MDRL) method is developed.

First, the network is divided into multiple subdomains managed by multiple local controllers, and the state information of each subdomain is flexibly obtained by the designed SDN multithreaded network measurement mechanism. Then, a cooperative communication module is designed to realize message transmission and message synchronization between the root and local controllers, and socket technology is used to ensure the reliability and stability of message transmission between multiple controllers to acquire global network state information in real time. Finally, after the optimal intradomain and interdomain routing paths are adaptively generated by the agents in the root and local controllers, a network traffic state prediction mechanism is designed to improve awareness of the cross-domain intelligent routing method and enable the generation of the optimal routing paths in the global network in real time.

Experimental results show that the proposed cross-domain intelligent routing method can significantly improve the network throughput and reduce the network delay and packet loss rate compared to those of the Dijkstra and open shortest path first (OSPF) routing methods.

Message transmission and message synchronization for multicontroller interdomain routing in SDN have long adaptation times and slow convergence speeds, coupled with the shortcomings of traditional interdomain routing methods, such as cumbersome configuration and inflexible acquisition of network state information. These drawbacks make it difficult to obtain global state information about the network, and the optimal routing decision cannot be made in real time, affecting network performance. This paper proposes a cross-domain intelligent SDN routing method based on a proposed MDRL method. First, the network is divided into multiple subdomains managed by multiple local controllers, and the state information of each subdomain is flexibly obtained by the designed SDN multithreaded network measurement mechanism. Then, a cooperative communication module is designed to realize message transmission and message synchronization between root and local controllers, and socket technology is used to ensure the reliability and stability of message transmission between multiple controllers to realize the real-time acquisition of global network state information. Finally, after the optimal intradomain and interdomain routing paths are adaptively generated by the agents in the root and local controllers, a prediction mechanism for the network traffic state is designed to improve awareness of the cross-domain intelligent routing method and enable the generation of the optimal routing paths in the global network in real time. Experimental results show that the proposed cross-domain intelligent routing method can significantly improve the network throughput and reduce the network delay and packet loss rate compared to those of the Dijkstra and OSPF routing methods.

Using recent US regional data associated with food system operations, this study aims at building optimization and econometric models to incorporate varying influential factors on food hub location decisions and generate effective facility location solutions.

Mathematical optimization and econometric models have been commonly used to identify hub location decisions, and each is associated with specific strengths to handle uncertainty. This paper develops an optimization model and a hurdle model of the US fresh produce sector to compare the hub location solutions between these two modeling approaches.

Econometric modeling and mathematical optimization are complementary approaches. While there is a divergence between the results of the optimization model and the econometric model, the optimization solution is largely confirmed by the econometric solution. A combination of the results of the two models might lead to improved decision-making.

This study suggests a future direction in which model development can move forward, for example, to explore and expose how to make the existing modeling techniques easier to use and more accessible to decision-makers.

The models and results provide information that is currently limited and is useful to help inform sustainable decisions of various stakeholders interested in the development of regional food systems, regional infrastructure investment and operational strategies for food hubs.

This study sheds light on how the application of complementary modeling approaches improves the effectiveness of facility location solutions. This study offers new perspectives on elaborating key features to encompass facility location issues by applying interdisciplinary approaches.

The United Arab Emirates (UAE) offers a level playing field to all ethnic entrepreneurs (EE’s) operating from within it. The purpose of this qualitative research case study is to explore the reasons underpinning the relatively greater success that Indian-origin EE’s in the UAE have been enjoying for sustained periods – and across diverse industries – relative to their counterparts belonging to several other nations.

Qualitative research case study that draws from data gathered through 30 interviews of participants identified through expert sampling.

Whereas the UAE treats all its ethnic entrepreneurs (EE’s) alike and provides them with a level platform to operate from, the EE’s from India have consistently been outperforming those from all other nations, particularly within the context of the UAE’s large businesses spanning diverse industries. Three features seem to explain their success: their high tolerance for ambiguity; thriftiness; and intercultural competence.

Two key limitations were faced: firstly, the negligible research literature on ethnic entrepreneurship in the UAE, and related official statistics such as details (by ethnicity/nationality) of EE-owned businesses, and secondly, the industry-wise break down of such businesses and their performance, as available in other developed nations hosting EE’s. Resultantly, alternate sources of data have been used to complete this research.

Given the UAE’s national-level institutionalised efforts to promote entrepreneurship amongst its citizens and wider populace, there are many implications that this study holds for existing and future entrepreneurs.

While on the one hand, the UAE and the wider Gulf Cooperation Council region have been witnessing frenetic ethnic entrepreneurial activity in the past decade, the research literature on the regions’ ethnic entrepreneurship is extremely patchy. This case study serves to significantly bridge this gap, and to the best of the authors’ knowledge, this is the first work, that extensively explores the entrepreneurial trajectory of Indian EE’s in the UAE, and the factors driving their success.

The Arab world has witnessed a remarkable surge in the growth of its tourism and hospitality (T&H) industry, positioning it as a vital cornerstone for sustainable development. However, an exclusive bibliometric analysis of T&H research contributed by the Arab world has not yet been conducted in the past 30 years, that is, 1993–2022. Therefore, the purpose of this study is to provide a first-of-its-kind bibliometric assessment and visualization of T&H research produced by the Arab world spanning from 1993 to 2022.

A comprehensive collection of 1,327 scientific publications related to T&H research contributed by the Arab world was acquired from the Web of Science Core Collection database. To perform a large-scale bibliometric analysis, encompassing performance analysis, science mapping and network analysis, this study used state-of-the-art analytical tools, namely, Bibliometrix package of R Studio and VOSviewer.

The findings of this study show that the Arab world’s research on T&H has significantly surged since COVID-19, contributing nearly half (50.56%) of the total literature in the T&H domain between 2020 and 2022. Elshaer IA (Suez Canal University, Egypt) emerged as the most productive author, while Nusair K (Sultan Qaboos University, Oman) was identified as the most impactful author in the T&H domain in the Arab world. The most productive journal was found to be Sustainability (MDPI), while Tourism Management (Elsevier) was identified as the most impactful journal in the field of T&H. Furthermore, the thematic analysis highlights that research themes in T&H are not static but rather constantly evolving in response to dynamic changes in the industry, such as emerging trends, shifts in tourist preferences and the impact of global events like the COVID-19 pandemic.

To the best of the authors’ knowledge, this is the first bibliometric analysis of T&H research contributed by the Arab world, specifically covering the period from 1993 to 2022. This study's findings can inform the development of strategies and policies for the sustainable and competitive growth of the T&H industry in the Arab world. This study highlights the importance of continued research and collaboration among industry professionals, academics and policymakers to promote innovation and drive positive change in the T&H sector in the Arab world.

阿拉伯世界已经目睹了其旅游和酒店（T&H）行业增长的显著激增, 将其定位为可持续发展的重要基石。然而, 在过去30年中, 即1993年至2022年, 尚未进行关于阿拉伯世界贡献的T&H研究的专属文献计量分析。因此, 这项研究代表了提供阿拉伯世界自1993年至2022年间T&H研究的首创性文献计量评估和可视化的先驱努力。

Making monetary policy decisions is a fine line to tread, always seeking to balance the needs of the domestic economic conditions with the need to keep events in the outside world under check. It is impossible to overstate the significance of monetary Trilemma in this context. This study aims to test the presence of monetary Trilemma and the contrasting dilemma hypothesis in India. The study is conducted over a considerable long span of time (1996–2022) to understand the evolution and changes in the management of Trilemma. In order to ascertain the changes in the existence of dilemma in India, this study analyses pre- and post-global financial crisis time periods. The relevance of exchange rate regimes in transforming Trilemma into a dilemma in the Indian context is assessed by providing for capital account restrictions. This evaluation helps to comprehend the impact of spillovers caused by monetary policy shocks in the United States and the resulting global financial cycle in India. The study provides evidence in favor of Trilemma and the relevance of exchange rate regimes as well as capital controls in determining monetary policy independence. The prevalence of more flexible exchange rate regimes favors a gradual shift toward dilemma, in situation of low capital controls.

Talent management can provide an organization with a competitive advantage. However, little is known about how human resource practices pertaining to talent management drive positive outcomes. Drawing on social exchange theory, this study investigates the effect of talent management practices usage on employee commitment and intention to leave. Integrating social exchange theory and the theory of met expectations facilitated predicting the mediating role of perceived career growth in the talent management practices usage-employee outcomes relationship.

Data were collected using a survey from 268 employees from eight organizations from the financial and services industries in Jordan.

Talent management practices usage has a significant direct positive effect on employee commitment but no direct effect on employees’ intention to leave. Further, there is pioneering evidence that perceived career growth mediates the following relationships: talent management practices usage and commitment and talent management practices usage and intention to leave.

The study provides unprecedented evidence of the effect of TM practices usage on employee outcomes and the role of perceived career growth in the TM practices usage-employee outcomes relationship from an underexplored context of Jordon. Our research results contribute to theory development in TM by supporting, extending and integrating social exchange theory and the theory of met expectations.

The study tests risk-taking and risk-aversion capabilities while distinguishing between business group firms and stand-alone firms and considering oil price volatility. Second, this attempt to study the linkage between risk-taking during market down movements and when the firms have established themselves as product market leaders. Third, this study analyses the “sentiment” state, where it explores the reaction of corporations when the market is in the negative direction, and lastly, it explores the linkage between product market competition and risk-aversion.

This study uses financial information for 1,273 non-financial companies and other required data from various sources. The study employs panel data and utilizes different empirical methodologies, including the generalized method of moments (GMM) estimator, to test the stated hypotheses.

We find that the business group firms have more risk-taking proficiencies compared with the stand-alone firms. Moreover, this study discovers that the corporates avoid taking risks when the market is not performing well. Also, when the market is down and crude prices are high, the management expects high earnings in the future, willingly takes risks and shows that product market leaders do not follow the risk-aversion strategy.

The empirical results indicate that oil price movement can restrict management’s behaviour when choosing a risky investment project. Management should develop a robust policy that follows the group of firms. In the policy, the management should describe the level of risk that may be taken by the firm and implement it when required.

Since we do not find any studies in this context, then there is a major and essential gap in the literature that this study should fill.

This paper aims to examine the effect of push and pull factors motivating international students to study abroad as two pre-departure factors to their mobility decision; and the effect of two post-departure factors – cultural distance and academic/university environment – on international students’ adjustment.

Data were collected from 339 international students studying in Egypt. Structural equation modeling (SEM) was used to assess the effect of the independent variables on two facets of adjustment, the cultural adjustment and the academic adjustment.

The descriptive studies showed differences in level of adjustments, where the academic adjustment was higher than the cultural adjustment. Moreover, the SEM results have confirmed the significant role of all studied variables on general cultural adjustment; and all variables except for the push factors, on interaction cultural adjustment; and the effect of only push and academic environment on academic adjustment.

This paper is an attempt to extend the work on international students’ mobility via identifying the main pre-departure and the post-departure factors affecting their decision to study in Egypt and the interplay of those factors in shaping their level of adjustment. This study is among a relatively limited attempts in the field that would link push and pull motivational factors to level of adjustment and via detecting the effects on two different adjustments dimensions: the cultural and the academic dimensions; and within an under researched context as Egypt.

Risk assessment in elder abuse is usually considered an additive process; risk factors are viewed as independent, and the higher the number of risk factors, the higher the risk. This study aims to explore the effect of the interaction between cognitive structures (episodic memory, perceptual speed, verbal fluency, executive function) and functional dependency on elder abuse.

The authors collected data from 62 participants, aged between 64 and 94 years old, in the Minho region of Portugal. Face-to-face interviews were conducted to apply the assessment procedures.

Results showed that emotional abuse is predicted by episodic memory and phonemic fluency, financial abuse by perceptual speed and phonemic fluency and neglect by perceptual speed. Moderation analysis showed that these effects were greater for older adults with higher dependence on movement and lower dependence on hygiene and daily organization. This study supports the hypothesis that the risk of elder abuse is interactive, highlighting a limitation of current risk assessment procedures.

The current study explores the possibility of risk factors for elder abuse interacting. Understanding how risk factors interact can help to design more accurate measures of the risk of elder abuse.
