This paper aims to evaluate effectiveness of cognitive behavioral intervention (CBI) to prevent substance use among first-year university students at high risk of substance use.

Abstract

Purpose

This paper aims to evaluate effectiveness of cognitive behavioral intervention (CBI) to prevent substance use among first-year university students at high risk of substance use.

Design/methodology/approach

Sixty university students at high risk for substance use recruited and assigned to CBI and control groups (30 students per groups). Intervention impact was assessed on measures of attitudes toward substance use at three time points: baseline, postintervention and three-months postintervention.

Findings

The analysis showed that participants’ negative attitudes toward substance use in the intervention group was increased post intervention. Although the mean score was significantly higher than the baseline (Time I) at Time II and dropped at Time III, the mean scores remained higher than time I, using repeated measure ANOVA (p < 0.05).

Practical implications

Findings of this study provide evidence that CBI is effective to sustain substance abstinence among this age group.

Originality/value

The paper is testing effectiveness CBI among a high-risk population of substance use. The study is highlighting the importance of sustaining substance abstinence using psychological preventive methods.

Abstract

Purpose

The purpose of this study is to identify the knowledge and management skills of health-care workers regarding psychosocial and mental health priorities and needs of individuals with COVID-19.

Design/methodology/approach

This is a cross-sectional descriptive study. The data collected conveniently from 101 health-care workers in Jordan directly managing care of individuals with COVID-19.

Findings

Health-care workers have moderate-to-high level of knowledge and management skills of psychological distress related to COVID-19; means ranged from 50%–70% agreement and confidence. In general, health-care workers were able to identify mental and psychosocial health needs and priorities at a moderate level. Health-care workers knowledge had a positive and significant correlation with age (r = 0.24, p = 0.012) and years of experience (r = 0.28, p = 0.004), and a significant difference was found in their management between those who are trained on psychological first aids and those who are not (t = −3.11, p = 0.003).

Practical implications

There is a need to train health-care workers to integrate psychosocial and mental health care to manage care psychological distress related to COVID-19.

Originality/value

This study is emphasizing the need for mental health psychosocial support training and in integration. Health-care workers providing care to individuals with COVID-19 are not aware of mental health priorities and needs of their patients. This paper contributes to the body of knowledge adding more understanding about competencies of health-care workers providing care and their preparedness to manage care individuals with COVID-19.

This paper aims to propose a new efficient semantic recommender method for Arabic content.

Abstract

Purpose

This paper aims to propose a new efficient semantic recommender method for Arabic content.

Design/methodology/approach

Three semantic similarities were proposed to be integrated with the recommender system to improve its ability to recommend based on the semantic aspect. The proposed similarities are CHI-based semantic similarity, singular value decomposition (SVD)-based semantic similarity and Arabic WordNet-based semantic similarity. These similarities were compared with the existing similarities used by recommender systems from the literature.

Findings

Experiments show that the proposed semantic method using CHI-based similarity and using SVD-based similarity are more efficient than the existing methods on Arabic text in term of accuracy and execution time.

Originality/value

Although many previous works proposed recommender system methods for English text, very few works concentrated on Arabic Text. The field of Arabic Recommender Systems is largely understudied in the literature. Aside from this, there is a vital need to consider the semantic relationships behind user preferences to improve the accuracy of the recommendations. The contributions of this work are the following. First, as many recommender methods were proposed for English text and have never been tested on Arabic text, this work compares the performance of these widely used methods on Arabic text. Second, it proposes a novel semantic recommender method for Arabic text. As this method uses semantic similarity, three novel base semantic similarities were proposed and evaluated. Third, this work would direct the attention to more studies in this understudied topic in the literature.

Abstract

Purpose

The purpose of this paper is to unveil the main changes in the UAE’s policy towards Iran since its foundation in 1971. The UAE favored strategic hedging, extending its commercial and diplomatic relations with Iran, in addition to developing its military capabilities and maintaining military/security alliances with Saudi Arabia and the USA. However, the UAE started to reorient its policy towards Iran by adopting some sort of balancing strategy in the aftermath of the Arab Spring of 2011. This paper examines how and why the UAE had to change course and explores whether it would revert back to strategic hedging with Iran.

Design/methodology/approach

The study will be carried out based on a theoretical framework drawn from strategic hedging theory, a new structural theory in international relations, to examine the shifts in UAE policy towards Iran. Previous literature suggests that small states prefer hedging over balancing or bandwagoning. The authors also undertake a descriptive analysis and deploy a longitudinal within-case method to investigate changes in UAE policy towards Iran and identify the causal mechanisms behind these changes. That method allows investigating the impact of a particular event on a case by comparing the same case before and after that event occurred.

Findings

The main finding of this study is that the UAE hedging strategy towards Iran allowed maximizing the political and economic returns from the cooperation with Iran and mitigating the long-range national security risks without breaking up the consistent and beneficial ties with other regional and global powers. Hedging achieved the desired outcome, which is preventing direct military confrontation with Iran. Hard balancing, adopted by Abu Dhabi after the 2011 Arab Spring, has proved to have some negative effects, most importantly provoking Tehran. Some recent indicators suggest, though that the UAE may revert back to its long-established hedging policy towards Iran.

Originality/value

Strategic hedging is a new structural theory in international relation, although hedging behavior in states’ foreign policies is far from new. It is new enough, thus, not have been researched sufficiently, strategic hedging still needs theorizing and comparison. This paper highlights the importance of strategic hedging as the most appropriate strategy for small states. It provides an important contribution to the application of the theory to the case of UAE policy towards Iran. The paper also assesses the conventional wisdom that small states prefer hedging over balancing in the light of the changes in the UAE foreign policy since 2011.

Abstract

Purpose

This paper aims to investigate the performance and working fluids screening for an ejector refrigeration cycle (ERC) activated by solar energy. Several common and new hydrofluorocarbons, hydrocarbons, hydrofluoroolefins and hydrofluoroethers are proposed as refrigerants for the ERC to determine the most appropriate one.

Design/methodology/approach

The ejector performance is characterized by the ejector area ratio (EAR) and entrainment ratio (ω), while the cycle performance is described by the coefficient of performance (COP). The influences of many working parameters like the evaporator, condenser and generator temperatures on the ejector and cycle performances are investigated for all candidates as well.

Findings

The results indicate that the best ejector and cycle performances are attained with the highest critical temperature dry refrigerant, i.e. R601 under all studied working conditions. From the perspective of energy efficiency and environmental issues, R601 can be considered the most appropriate working fluid amongst all candidates. However, extra attention should be considered against its flammability. The maximum COP, the corresponding ω and the necessary EAR using R601 are 0.743, 1.02 and 15.5, respectively, with 25 ºC condenser temperature and the typical values for the rest operating conditions.

Originality/value

Many common and new hydrofluorocarbons, hydrocarbons, hydrofluoroolefins and hydrofluoroethers are suggested as working fluids for the ERC to determine the most appropriate one. The mixing process inside the ejector constant-area section is assumed constant-pressure process.

Abstract

Purpose

The purpose of this paper is to argue that it is possible to identify a number of physical design properties of plots that are associated with coastal alteration and to develop a predictive model or metric to evaluate the potential alteration caused by that resort. Investors may have economic plot size concerns not considered by planners, tourists may prefer close proximity to deep waters, and urban planners may have failed to realize the importance of certain plot ratios or minimum dimensions etc.

Design/methodology/approach

A combination of geographical information system and statistical tools is used to identify and model these properties. The research uses data from three different resorts in two countries along the Red Sea coast (Hurghada and Safaga in Egypt and Jeddah in Saudi Arabia). Landsat TM7 images are obtained for each location and analysed to detect regions with the largest alteration along the coast using the post‐classification change technique. Physical properties of each village are generated using ArcGIS 9.2 both before and after alteration. Finally, a predictive decision‐support tool for urban planners and environmental auditors is formulated using stepwise discriminant analysis.

Findings

Two‐step cluster analysis and discriminate analysis show that alteration takes place based on factors that include original width and original distance to deep water in three distinct groups. The predictive model that is developed classifies any given resort into one of three clusters, by virtue of their physical design characteristics. This gives a rough prediction of the likely alteration that might take place under a given condition. Subdivision plans that ignore the power of these two factors literally “invite” owners to violate shorelines and encroach on the sea. Planners are urged to join hands with policy makers and developers to formulate guidelines to plot subdivision and environmentally acceptable design solutions to facilitate access to deep water.

Originality/value

Till now, there has been no metric to relate a plot's geometric properties with the encroachment it makes. If such an association could be made, a developer's resort plans may be evaluated to predict the degree by which an encroachment is likely. The model can be used to identify resorts whose properties present a risk to shorelines, dredge or fill to maximize usable land. Two benefits may be thought of for this approach. First, the model helps urban planners develop a sustainable coastal area by bearing in mind the needs of tourist‐developers as well as the properties of their adjacent coast. Second, the factors can be used to rationalize building guidelines and land use regulations to minimize such risk.

Abstract

Purpose

This study aims to investigate the nature of the relationship between the state and civil society after the 2011 uprising.

Design/methodology/approach

The study adopted Mygdal’s approach to analyze the relationship between the state and civil society and identify their ability to control the rules of the political game. The study also draws on the theoretical framework of the hypotheses introduced by a number of scholars on the forms of potential relations between the state and civil society, and the impact of these forms on advancing the process of democratization.

Findings

This study argues that despite some important changes in favor of civil society vis-à-vis the state, it is too early to conclude that a dramatic change has occurred in this relationship, due to a discernable unbalanced power in favor of the state. The state revealed after 2011 that these organizations acted against the state’s stability and against its fundamentals.

Originality/value

To the best of the author’s knowledge, this research is the first to study the relationship between the state and the civil society in Egypt after 2011 events.

Abstract

The primary purpose of this chapter is to examine some old truths about leadership at the CEO level, and to summarize a new perspective based on charismatic leadership theory that could help cast light on this important area of strategic management. In so doing, we attempt to move charismatic leadership theory in some new directions by bridging micro-and macro-level conceptualizations. The upper echelons perspective from the strategic management literature is first summarized. We then identify problems in conceptualization and measurement that have served to limit the usefulness of this theoretical approach with regard to understanding the leadership role and effects of CEOs. We present two alternative new models that incorporate the constructs of strategic change, CEO charisma, and perceived environmental uncertainty. Data are also presented, suggesting mixed support for the models. Suggestions are made with regard to future quantitative and qualitative research.

To provide an overview of emerging concepts in the field of cross‐cultural management, which could augment/supplant the contributions made by Hofstede and Trompenaars.

Abstract

Purpose

To provide an overview of emerging concepts in the field of cross‐cultural management, which could augment/supplant the contributions made by Hofstede and Trompenaars.

Design/methodology/approach

The contributions made by well‐known researchers in the field of cross‐cultural management, such as Hofstede and Trompenaars is critiqued so that the reader can have an idea of what the existing lacuna in this field are. This critique is followed by a discussion of recent research endeavours, which are taking into account these lacuna. A polemic is built around the theme of how the grand typologies of Hofstede and Trompenaars may now have outlived their utility.

Findings

Provides an analysis of the shortcomings of Hofstede's and Trompenaars's contributions. Examines how emerging concepts like crossvergence and multiculturalism serve to make research in the area more meaningful and relevant. Focuses on how management practices found effective in one culture, can be transplanted to other cultures and embedded there.

Research limitations/implications

Only a few selected emerging concepts have been considered.

Practical implications

The direction in which future research should be carried out so as to have practical validity is delineated.

Originality/value

The paper has suggested that it is time to move forward and even away from the contributions made by Hofstede and Trompenaars. It has also pointed out the direction in which current researchers in the field are attempting to do this.

Abstract

Purpose

The purpose of this study is to identify similarities and differences between the leadership practices of managing entrepreneurs and professional CEOs and to investigate how these impact on their immediate subordinates' satisfaction, commitment, motivation, and effectiveness (engagement).

Design/methodology/approach

A multiple‐respondents survey, aiming at CEOs and their immediate subordinates, was conducted. Factor analysis, correlations and moderated regression analysis were used in order to reach conclusions.

Findings

Two leadership dimensions are found to be most influential: being a good manager/mentor and articulating vision. Although good manager/mentor characteristics prove crucial for both types of CEOs, the effect of vision articulation on subordinates is moderated by the type of company the CEO is leading. No significant differences are found in the leadership style that the two types of CEOs adopt, except for their calmness and self‐possession, which is lower among entrepreneurs.

Practical implications

The findings raise questions regarding the differences in subordinate expectations from owners – CEOs, as opposed to professional CEOs; and point at certain characteristics which could be developed in order to enhance leadership effectiveness in both groups of top managers.

Originality/value

The study underlines the importance of sound vision development and articulation in entrepreneur‐run firms, as it appears that people working for such firms expect more direction from the Head. It is also sustained that good management and mentoring are essential in any kind of firm, in order to develop an effective, committed and motivated top management team, which will bring corporate success.
