A sheet metal forming simulation code has been developed, based on the explicit time integration scheme and Mindlin shell theory. It has been used for the analysis of a number of industrial parts. After recalling some modelling issues, this paper describes an industrial methodology based on the experience of those analyses. The aim of the methodology is to provide, at early design stage, information on the product formability with a workload and lead time adapted to the design delays. Concurrently 2D analyses, critical zones studies and coarse mesh global investigations can be used, with a flexible number of iterations, prior to full refined analyses of the forming process. The application of the methodology on several industrial examples is discussed.

This paper gives a review of the finite element techniques (FE) applied in the area of material processing. The latest trends in metal forming, non‐metal forming and powder metallurgy are briefly discussed. The range of applications of finite elements on the subjects is extremely wide and cannot be presented in a single paper; therefore the aim of the paper is to give FE users only an encyclopaedic view of the different possibilities that exist today in the various fields mentioned above. An appendix included at the end of the paper presents a bibliography on finite element applications in material processing for the last five years, and more than 1100 references are listed.

This study aims to examine the correlation between the readability of financial statements and the likelihood of future stock price crashes in nonfinancial companies listed on the Egyptian Stock Exchange. It further explores the possible moderating effect of audit quality on this relationship.

The study uses ordinary least squares regression, generalized least squares estimation and two-stage least squares methodology to examine and validate the research hypotheses. The sample comprises 107 nonfinancial companies registered on the Egyptian Stock Exchange from 2016 to 2019.

The results reveal a significant negative association between the readability of financial statements and stock price crash risk. This suggests that companies with more complex financial statements tend to experience higher future crash risks. Additionally, the study identifies audit quality as a significant moderating factor. Higher audit quality, often indicated by engagements with Big-4 audit firms, strengthens the influence of financial statements readability on stock price crash risk. This implies that while high audit quality enhances investor confidence and market stability, it also accentuates the negative consequences of complex financial statements.

The findings of this paper have significant implications for regulators and standard-setting bodies in Egypt. They should consider refining and revising existing standards to emphasize the importance of enhancing the readability of financial reports. Additionally, auditing firms should actively engage in efforts to ensure clearer and more transparent financial reporting. These actions are vital for boosting investor confidence, strengthening Egypt’s capital market and mitigating potential risks associated with information opacity and complexity.

This study represents a pioneering endeavor within the Arab and Egyptian financial environments. To the best of the author’s knowledge, it is the first examination of the association between the readability of financial statements and stock price crash risk in these contexts. Furthermore, it explores factors such as audit quality that may influence this connection.

The purpose of this study is to outline components of a proposed screen-in (not out) hiring process for police.

This study uses survey data collected from police officers of all ranks (n = 166) in one Arizona police department, exploring officer perceptions of the most important qualities necessary to be an exceptional police officer, as well as the optimal processes for finding people with those traits.

Results build on prior studies that have begun to identify sought-after traits including honesty, integrity, ethics, compassion, empathy, as well as communication and listening skills. Findings also suggest preliminary steps for finding good cops through expansion of existing screen-out processes to also screen-in desirable prospects, application of some academy training processes to the hiring pool, and more proactive recruitment efforts.

This study adds value to the extant literature on the characteristics of good policing and on identifying the qualities by which to “screen-in” officers during the hiring and recruitment process. Further, the authors expand this understanding by capturing perceptions of the best processes to identify individuals with desirable qualities during the hiring and recruitment process. The implications of these findings are used to initiate a discussion of foundational components of a screening-in hiring process for police, informed by both empirical research and community perspectives.

This paper focusses on how the educated and less-educated middle class react differently to income increases, against an intertwined literature backdrop of Engel's law, quality of life, aspirational and conspicuous consumption. The paper seeks to answer two main questions: Is there evidence of the middle class, particularly the educated, trying to emulate the upper class by shifting towards aspirational consumption? Is there any distinct expenditure behaviour amongst the middle class?

Combining the Malaysian 2016 Household Expenditure Survey (HES) and the 2016 Consumer Price Indices datasets, quantile estimations are applied on the merged dataset of 14,326 households.

There is evidence of the educated middle class emulating the upper class in terms of food share, home furnishing and starchy produce expenditure behaviour. The less-educated middle class exhibits a predilection for home furnishing expenditures when income increases, whilst the educated shows signs of dissociating themselves from such material acquisitions. The paper concludes that the middle class is collectively an aspirational class, but with diverging paths towards upward social mobility between the educated and less-educated households.

Aspirational consumption of the middle class has not been given detailed empirical treatment at the household micro-level in the literature, especially for upper-middle income countries like Malaysia. The paper starts off by detecting an anomaly in the Engel's food share coefficients, where the middle class sees unexpected larger declines in food share than those of the upper class. This is the paper's departure point from the literature.

To recognize the existing state of knowledge on a culture of excellence (CoE) in higher education institutions (HEIs) and to define the CoE in HEI and the dimensions that make up that culture. A subsidiary goal is to propose a qualitative tool to measure CoE maturity.

The study was based on the qualitative method, the preferred reporting system of systematic reviews and meta-analysis (PRISMA). Next, the conceptual work method was used.

A research gap in the topic of CoE in HE has been confirmed. The CoE's own definition has been proposed, as well as a set of seven dimensions that comprise it, such as: Clear vision, mission and goals for excellence; Leadership oriented to excellence; Employee engagement; Human resources management; Meeting and exceeding student and staff expectations; Continuous improvement of processes through innovation and excellent practices; and Partnership and teamwork for improvement.

The study research was limited to open-access articles. Therefore, in the future, the search can be broadened to include monographs or doctoral dissertations, and other peer-reviewed studies. The research implications are related to the originality of our work and the proposals of two concepts – a CoE model and a CoE maturity assessment tool.

Leaders at universities, e.g. rectors and deans, can take into account the identified dimensions and progressively provide them as conditions conducive to achieving above-average levels.

This is the first literature review on CoE in HEIs, which can be considered an original contribution to science and practice. The original contribution of the paper is also the proposal of a CoE conceptual model and a CoE maturity assessment tool.

The purpose of this paper is to embark on evaluating the role of Chat Generative-Trained Transformer (ChatGPT) in personal knowledge management (PKM) practices of individual knowledge workers across varied disciplines.

The methodology involves four steps, i.e. literature search, screening and selection of relevant data, data analysis and data synthesis related to KM, PKM and generative artificial intelligence (AI) with a focus on ChatGPT. The findings are then synthesized to develop a viewpoint on the challenges and opportunities brought by ChatGPT for individual knowledge workers in enhancing their PKM capability.

This work highlights the prevailing challenges and opportunities experienced by knowledge workers while leveraging PKM through implying ChatGPT. It also encapsulates how some management theories back the cruciality of generative AI (specifically ChatGPT) for PKM.

This study identifies the challenges and opportunities. from existing studies and does not imply empirical data/result. The authors believe that findings can be adjusted to diverse domains regarding knowledge workers’ PKM endeavors. This paper draws some conclusions and calls for further empirical research.

ChatGPT’s capability to accelerate organizational performance compelled scholars to focus in this domain. The linkage of ChatGPT to Knowledge Management is an under-explored area specifically the role of ChatGPT on PKM hasn't been given attention in the existing work. This is one of the earliest studies to explore this context.

Health fitness has become a major issue in Malaysia since the population of overweight and obesity is becoming critical. One of the ways to achieve optimum health fitness is by consistently consuming balanced diet meals. Hence, this paper aims to focus on the willingness of society to purchase functional foods as an alternative for their daily meals to stay fit.

The research framework was developed based on a combination of findings by other research scholars within a similar field. The willingness to purchase functional foods to stay fit is positioned as the dependent variable, while lifestyle adaptation, social media influence and food consumption awareness are placed as the independent variables. Quantitative research was conducted by collecting primary data from respondents in Kuala Lumpur, Malaysia. The collected data were analysed using descriptive and regression analyses.

The willingness to purchase functional foods to stay fit is dependent on the lifestyle adaptation, social media influence and food consumption awareness.

Although the current market for functional foods in Malaysia is still at a small scale, the market for this industry seems very promising. Nevertheless, greater awareness on functional food is still needed.

Functional food producers should make an effort to gain the untapped market by focussing on the lifestyle adaptation, social media influence and food consumption awareness.

This research is a breakthrough to discover the willingness of Malaysians to purchase functional food to stay fit, which is influenced by lifestyle adaptation, social media and food consumption awareness.

This study aims to focus on the main materials used in consolidation processes of illuminated paper manuscripts and leather binding.

For each material, chemical structure, chemical composition, molecular formula, solubility, advantages, disadvantages and its role in treatment process are presented.

This study concluded that carboxy methyl cellulose, hydroxy propyl cellulose, methyl cellulose, cellulose acetate, nanocrystalline cellulose, funori, sturgeon glue, poly vinyl alcohol, chitosan, chitosan nanoparticles (NPs), gelatin, aquazol, paraloid B72 and hydroxyapatite NPs were the most common and important materials used for the consolidation of illuminated paper manuscripts. For the leather bindings, hydroxy propyl cellulose, polyethylene glycol, oligomeric melamine-formaldehyde resin, acrylic wax SC6000, pliantex, paraloid B67 and B72, silicone oil and collagen NPs are the most consolidants used.

Illuminated paper manuscripts with leather binding are considered one of the most important objects in libraries, museums and storehouses. The uncontrolled conditions and other deterioration factors inside the libraries and storehouses lead to degradation of these artifacts. The brittleness, fragility and weakness are considered the most common deterioration aspects of illuminated paper manuscripts and leather binding. Therefore, the consolidation process became vital and important to solve this problem. This study presents the main materials used for consolidation process of illuminated paper manuscripts and leather bindings.

Evidence suggests that the percentage of men seeking treatment for substance use disorders and other addictive behaviours is significantly higher than that of women. This fact raises several crucial questions concerning the field of addictions. This paper aims to emphasize to the study of addiction in the light of gender studies and especially in the light of theories of dominant/hegemonic masculinity.

The perspective of dominant/hegemonic masculinity in the field of addictions raises a number of questions: Can the dominant/hegemonic masculinity perspective contribute to the understanding of the phenomenon of addiction? What are the implications of male-dominated and male-centred treatment services on meeting the needs of other populations? Are androcentric approaches ultimately helpful for heteronormative men? This paper investigates the emerging questions through a critical review of the literature including the disciplines of psychology, sociology and anthropology.

The perspective of hegemonic masculinity can make an important contribution to the understanding of addiction as it sheds light on a dimension that is not well researched and used in the field of addictions. The influences of the androcentric approach to addiction treatment are significant and pose problems both in accessing and serving the needs of other populations. The androcentric approach to treatment is not helpful for heteronormative men either as there is a risk of not addressing the toxic dimensions of dominant/hegemonic masculinity that are directly linked to the problem of addiction.

This paper poses interesting research questions for further research in the field.

This paper raises important issues for practitioners in the field and at the same time suggests alternative perspectives on the interpretation and treatment of addiction.

The gender perspective that should further enrich psychosocial interventions is crucial for the equal access of all people with an addiction problem to appropriate support structures.

Gender studies can make an important contribution to further understanding of addiction problems and to the development of effective practices for dealing with it. The fact that in substance abuse treatment programmes the vast majority of participants are heteronormative men raises a number of concerns. These concerns relate to the extent to which structures are directed at meeting the needs of these men and whether because of this orientation the needs of other populations such as heteronormative women and those who do not meet the norms of heteronormativity are left uncovered. These concerns are linked to broader considerations of the role that dominant/hegemonic masculinity plays in the aetiology of addiction and in creating barriers to help-seeking for heteronormative men themselves.
