Abstract

Purpose

This study aims to assess the effect of updating the Phase I data – to enhance the parameters' estimates – on the control charts' detection power designed to monitor social networks.

Design/methodology/approach

A dynamic version of the degree corrected stochastic block model (DCSBM) is used to model the network. Both the Shewhart and exponentially weighted moving average (EWMA) control charts are used to monitor the model parameters. A performance comparison is conducted for each chart when designed using both fixed and moving windows of networks.

Findings

Our results show that continuously updating the parameters' estimates during the monitoring phase delays the Shewhart chart's detection of networks' anomalies; as compared to the fixed window approach. While the EWMA chart performance is either indifferent or worse, based on the updating technique, as compared to the fixed window approach. Generally, the EWMA chart performs uniformly better than the Shewhart chart for all shift sizes. We recommend the use of the EWMA chart when monitoring networks modeled with the DCSBM, with sufficiently small to moderate fixed window size to estimate the unknown model parameters.

Originality/value

This study shows that the excessive recommendations in literature regarding the continuous updating of Phase I data during the monitoring phase to enhance the control chart performance cannot generally be extended to social network monitoring; especially when using the DCSBM. That is to say, the effect of continuously updating the parameters' estimates highly depends on the nature of the process being monitored.

Abstract

Purpose

The level of mental alertness among students who are in need of study in the preparatory year – Imam Abdul Rahman Bin Faisal University. The level of self-competence of female students who are in need of study in the preparatory year – Imam Abdul Rahman Bin Faisal University. To learn about the relationship between mental alertness and self-competence among students who are in need of study in the preparatory year – Imam Abdul Rahman Bin Faisal University.

Design/methodology/approach

The researchers used the experimental method by following the experimental design with two measurements, tribal and posterior, for two groups, one experimental and the other control, due to its suitability to the nature of this research. Research sample: the research community included female students stumbling in the scientific path of Rayyan, the second semester of the academic year 2020–2021 AD, where the researchers selected the research sample in a deliberate manner from the stalled students of 25 students and a random sample of 10 female students was withdrawn to conduct the exploratory study. The number of the basic research sample is 15 female students. Reasons for selecting the search sample: all of the sample members are female students stumbling in the scientific path of Al-Rayyan for the academic year 2020–2021 and all sample members agree to apply the research.

Findings

The researchers refer to this to the virtual psychological guidance program-specific objectives, as well as the follow-up of the scientific principles and principles and the legalization of the measurement tools used in the research and the diversity of the program within the parts of the program and the training sought to develop the ability to manage pressures and emotions and training in social skills, awareness and self-awareness and the use of exercises relaxation, breathing and modern self-help, as well as the use of different methods and techniques such as the method of dialogue, discussion, awareness of feelings and problem-solving, which led to a change in behavior and personal characteristics, which led to a change in behavior and personal characteristics, leading to the development of behavior and personal characteristics.

Originality/value

The study aims to design a hypothetical psychological counseling program as a method of health care and its effect on the level of mental alertness and the level of self-efficacy of students who have struggled to study at the Deanship of the preparatory year – Imam Abdul Rahman bin Faisal University. The researchers used the experimental approach and applied this study on a sample of 25 students from the students who failed to study at the Deanship of the preparatory year for the second semester of the academic year 2020–2021 AD and the most important results were that the psychological counseling program as a method of health care had a positive effect on improving the level of mental alertness and the level of self-efficacy among the students who had failed to study. There is a positive correlation between the level of mental alertness and self-efficacy of struggling students as a way of health care.

Abstract

The MENA (Middle East and North Africa) region is in a critical moment in its information and news ecology, exhibiting signs of pretruth and posttruth syndromes. Between the “pretruth” and “posttruth” there is a gap that circumvented “truth.” The state of information in the MENA region brings back the dystopian Orwellian notion of the “Ministry of Truth.” A poetic term in anticipation of this moment of the crisis of truth. Sharing the latter with the rest of the world, the pretruth moment is engraved in the region's history of precarious political and religious authoritarian control and manipulation of information and news and low press freedom. In the region, truth is told, hidden, distorted, and manufactured by a blend of humans and bots, where both artificial intelligence and social humans are involved in this process of multipolarized disinformation operations with multifarious sponsors, actors, and beneficiaries that have distinct and often clashing agendas and interests. To understand the ecology of truth, facts, news, and information in the Middle East, studies ought to be situated within the ecosystem of information and media technologies in the globalized national and transnational societies of the region and consider both the role of the regionally oriented neoauthoritarian regimes and that of interested rising and established global powers. Central to this ecosystem is the dynamic interaction among three actors: communication technologies (the focus here is on the Internet); media, public, and activists' use of these technologies to mobilize, inform, and present alternative narratives, and to resist or confirm state narratives; and the authoritarian political regimes and their containment strategies for legacy media (particularly television) and the Internet.

Abstract

Purpose

The purpose of this research paper is to study the relationship between entrepreneurial marketing strategy (EMS), institutional environment (IE) and business performance (BP). Further, it examines the role of gender and entrepreneurial experience (EE) as moderators of EMS-BP and IE-BP relationships.

Design/methodology/approach

Based on the literature review, the authors proposed a conceptual model that was tested using a quantitative approach. Questionnaires were filled by 202 owners/entrepreneurs of small- and medium-sized enterprises (SMEs) in Egypt. Because of the absence of a formal population-frame for the Egyptian SMEs, non-probability quota sampling technique was used that considered differences in gender and EE. SmartPLS software was used for data analysis.

Findings

The results indicated that EMS has significant positive effect on BP. IE has significant positive effect on EMS but insignificant effect on BP. Gender was found to be moderating significantly both the EMS-BP and IE-BP relationships. However, EE was found to be an insignificant moderator in the EMS-BP relationship.

Practical implications

The findings communicate insights to the SMEs on the importance of undertaking proactive, risk-taking and innovative activities while creating and delivering value to their customers. Also, it encapsulates further implications for policymakers to promote a better IE for entrepreneurship in Egypt.

Originality/value

This study contributes conceptually to the interdisciplinary research that investigated the integration between entrepreneurship and marketing as a successful functional strategy in SMEs and its effect on enhancing BP and market share. Empirically, it adds value to the available literature on contemporary strategic entrepreneurship by analysing these IE-EMS-EE-Gender-BP relationships in a promising, yet under-researched, transitional economy.

Abstract

Purpose

This study aims to investigate the differences in spatial ability between students with a math learning disability and their normal peers.

Design/methodology/approach

To investigate these differences two groups, (60 students with a math learning disability) and (60 normal students) from fifth grade with a mean age (10.6 years) were administered with spatial ability test along with an IQ test. Students with a math learning disability were chosen using measures of the following: math learning disability questionnaire developed from learning disability evaluation scale – renormed second edition (LDES-R2) (McCarney and Arthaud, 2007) and the Quick Neurological Screening Test (Mutti et al., 2012), in addition to their marks in formal math tests in school.

Findings

Comparison between the two groups in four aspects of spatial ability resulted in obvious differences in each aspect of spatial ability (spatial relations, mental rotation, spatial visualization and spatial orientation); these differences were clear, especially in mental rotation and spatial visualization.

Originality/value

This paper contributes to gain more insights into the characteristics of pupils with a math learning disability, the nature of spatial abilities and its effect on a math learning disability. Moreover, the results suggest spatial ability to be an important diagnose factor to distinguish and identify students with a math learning disability, and that spatial ability is strongly relevant to math achievement. The results have significant implications for success in the science, technology, engineering and mathematics domain.
