To delve further into the phenomenon of psychological pressure on single mothers, the purpose of this paper is to explore the factors that affect the psychological state of single mothers in Vietnam.

Interpretative phenomenological analysis (IPA) interviews were conducted and analysed with the aim of understanding the psychological state of single mothers sampled from a social group in Vietnam.

Single mothers lack direct support needed to improve their confidence, job opportunities, income levels and social status. The absence of interventions increases the psychological pressure on single mothers in Vietnam.

A future study can explore the psychological state of single mothers using a more expansive data set.

Understanding the psychosocial and socio-economic risk factors of postpartum psychological pressure in single mothers may have important implications on preventative and support measures, as well as laying the groundwork for social protection interventions and informing welfare policy-making at a national level.

Social constructs in Vietnam compound the effect of postnatal depression on Vietnamese single mothers (in contrast to their counterparts in developed Western nations). This means that researchers and policymakers need to reconstruct stigmas that cause psychological pressures on single motherhood, and in doing so, help to change the view held about single motherhood.

This study is the first to explore psychological state of mothers in Vietnam using IPA.

The potential of the Internet as a valuable methodological research tool is increasingly being recognised by both market researchers and academics. This paper contributes to the debate surrounding virtual synchronous group interviews and the value of online research. Specifically it introduces the use of a software conferencing technique – Hotline Connect – and discusses the implications of using the technique for Internet‐based research. In particular, issues of interview design, developing rapport and the virtual venue are considered. The paper draws on the experience of a recent research project entitled “cyberparents” and concludes that the use of conferencing software holds great potential for synchronous online interviewing. However, this must be combined with sensitive, ethical handling of both the research process and the data to overcome problems inherent in any interviewing situation.

Over the past three decades, numerous conceptual and empirical studies have discussed momentum investment strategies’ presence, pervasiveness and persistence. However, science mapping in the field is inadequate. Hence, this study aims to comprehend and explore current dynamics, understand knowledge progression, elicit trends through thematic map analysis, synthesize knowledge structures and provide future research directions in this domain.

The study applies bibliometric analysis on 562 Scopus indexed articles from 1986 to 2021. Biblioshiny version 3.1.4, a Web-based application included in Bibiliometrix package developed in R-language (Aria and Cuccurullo, 2017), was used to examine: the most prominent articles, journals, authors, institutions and countries and to understand the thematic evolution and to elicit trends through the synthesis of knowledge structures including conceptual, intellectual and social structures of the field.

Motor themes, basic transverse, niche and emerging and declining themes were identified using (Callon, 1991) strategic thematic map. Besides, four major clusters based on a cocitation network of documents were identified: empirical evidence and drivers of momentum returns, theories explaining momentum returns and implications for asset pricing and market efficiency, avoiding momentum crashes and momentum in alternative asset classes, alternative explanations for momentum returns. The study infers that momentum research is becoming multidisciplinary given the dominance of behavioral theories and economic aspects in explaining the persistence of momentum profits and offers future research directions.

The study deploys bibliometric analysis, appropriate for deriving insights from the vast extant literature. However, a meta-analysis might offer deeper insights into specific dimensions of the research topic. Besides, the study’s findings are based on Scopus indexed articles analyzed using bibilioshiny; the database and software limitations might have affected the findings.

The study is a ready reckoner for scholars who intend to recognize the evolution of momentum investment strategies, current dynamics and future research direction. The study offers practitioners insights into efficiently designing and deploying momentum investment strategies and ways to avoid momentum crashes.

The study offers insights into the irrational behavior and systematic errors committed by market participants that helps regulators and policymakers to direct investors’ educational efforts to minimize systematic behavioral errors and related adverse financial consequences.

This comprehensive study on momentum investment strategies evaluates research trends and current dynamics draws a thematic map, knowledge progression in the field and offers future research directions.

The purpose of this study is to explore the current literature which assesses the incidence of completed or attempted mass shooting events in which a female party acted either alone or as an accomplice; explore the involvement of women in the planning or execution of acts of terrorism; evaluate the pathology of women involved in these acts of extreme violence; highlight any gender-specific pathological and environmental risk factors associated with the planning or completion of the mass shooting, spree killing or terrorist attack events.

Using the 27-item preferred reporting items for systematic reviews and meta-analyses guidelines (Moher et al., 2009), the present systematic review explored peer-reviewed literature published between 1908 and September 2020 using six databases [SalfordUniversityJournals@Ovid; Journals@Ovid Full Text; APA PsycArticles Full Text; APA PsycExtra; APA PsycInfo; Ovid MEDLINE(R)], in addition to conducting a grey literature search on “Google Scholar” using specific search terms, predetermined following use of the patient/population, intervention, comparison framework.

Findings of the review did identify several distinguishing characteristics exclusive to women allied to terror organisations; including lower levels of extremism and religious ideology, lower age of radicalisation, higher levels of education than currently hypothesized and the significance of relational affiliation with extremist causes. Despite the synthesis of descriptive characterises being achieved, data relating to female mass shooters was scant and relied upon case study review and discussion. As a result, identification of precipitating psychopathological and environmental triggers was difficult, however, there does appear to be a higher proportion of female mass shooters targeting current or previous places of employment.

One of the potential limitations of this review is that some relevant studies were not identified during the search. The risk of this was minimised as much as possible by screening the reference section of relevant reviews and theoretical papers (which were identified in the search of the databases) for any potentially relevant studies that may have been missed. In addition, numerous permutations of the search criteria that were entered into the databases were also entered into “GoogleScholar”.

Current literature has highlighted that the age of radicalisation among women across both jihadi-inspired, right-wing and far-left extremist organisations are decreasing, with many new recruits being born after 1990 (Jacques and Taylor, 2012). This finding aids in identifying a target of entry to minimise the chance of radicalisation, through targeted educational training and anti-radicalisation programmes intervening in at risk groups at the correct time. However, further exploration will be necessary to identify specific risk factors prior to radicalisation in such groups.

There appears to be a large gap in literature quantitively assessing the rates of psychopathological variables among this demographic. When narrowing the lens further onto female mass shooters, empirical literature investigating even characteristic variables continues to evade the academic remit. Arguably this obstruction to the current understanding of female perpetrated violence, both in an organised terror and a mass shooter capacity, limits the ability to meaningfully evaluate whether previous models assessing risk among mass shooters is valid across genders.

With past studies indicating a lack of skill development in engineering education, there is a need for new pedagogical tools that are application and skill-oriented. Hackathons are widely accepted in the corporate world, in the engineering domain for skill development and recruitment but have not gained acceptance in mainstream engineering education. Very few studies have discussed engineering educator views regarding hackathons and their benefits. This paper intends to study engineering educators' perception of the hackathon and its benefits after participating in it. The findings could support hackathons as a pedagogical tool to develop an industry-oriented and skill-based engineering education.

A mixed methods design was employed where initially qualitative study was conducted. Its findings were used to conduct survey of 162 engineering educators who had participated in a hackathon. A five point Likert scale was employed for data collection.

The findings reveal that engineering educators who participated in the hackathon perceived hackathons to support industry-focused learning, problem-solving and new skill development. They also acknowledged its role in their professional development. The further discussion suggests that engineering educators and institutes may collaborate with industry to design and use hackathons as a teaching tool to develop industry-ready graduates.

The study was not designed to study how different aspects of hackathon lead to different benefits derived from participating in it. There is a need to study hackathons as a tool of pedagogy and assessment, focusing on how variables linked to it facilitate, moderate and hinder the learning and assessment process in participants. More in-depth studies need to be conducted to adopt the hackathon as a pedagogy and assessment tool in higher education.

The discussion suggests that designing hackathons effectively as a tool for learning and skill development will result in skilled graduates. Engineering educators should adopt hackathons as a pedagogy for their students. Management and policymakers of engineering institutes should consider hackathons as a part of pedagogy for students besides conducting hackathons for educators for their professional development that will be investment in skills helpful at workplace.

The notable contribution of this paper is to document perceptions of engineering educators regarding hackathons and their benefits after participating in a hackathon. The paper proposes that hackathons can be introduced in the engineering curriculum as they would offer educators a novel method of teaching and assessment and support engineering graduates in recruitment and making them industry-ready.

This article is not the work of an expert on the period in question (see Robinson, 1971; Rheinwald, 1977); rather it is a commentary on a book whose half‐century has just passed almost unnoticed. In a sense the argument involves a further visit to what J.A. Schumpeter once described as the “lumber room” of historical knowledge, although this particular visit is prompted neither by nostalgia nor piety, but rather by the conviction that Chamberlin still has much to teach those interested in the theory of the firm and in the wider area of industrial economics. The article is also prompted by the conviction that the conventional textbook accounts of Chamberlin's work have introduced misleading simplifications in pursuing the qualities of coherence and precision in the presentation of ideas.

Selective laser melting and electron beam melting processes are well-known for the additive manufacturing of metal parts. Metal powder bed fusion (MPBF) is a common term for them. The MPBF process can empower the manufacturing of intricate shapes by reducing the use of special tools, shortening the supply chain and allowing small batches. However, the MPBF process suffers from many quality issues. In literature, several works are recorded for qualification of the MPBF part. The purpose of this study is to recollect those works done for quality control and report their helpful findings for further research and development.

A systematic literature review was conducted to highlight the major quality issues in the MPBF process and its root causes. Further, the works reported in the literature for mitigation of these issues are classified and discussed in five categories: experimental investigation, finite element method-based numerical models, physics-based analytical models, in-situ control using artificial intelligence (AI) and machine learning (ML) methods and statistical approaches. A comparison is also prepared among these strategies based on their suitability and limitations. Additionally, improvements in MPBF printers are pointed out to enhance the part quality.

Analytical models require less computational time to simulate the MPBF process and need a smaller number of experiments to confirm the results. They can be used as an efficient process parameter planning tool to print metal parts for noncritical applications. The AI-ML based quality control is also suitable for MPBF processes as it can control many processing parameters that may affect the quality of the MPBF part. Moreover, capabilities of MPBF printers like thinner layer thickness, smaller beam diameter, multiple lasers and high build temperature range can help in quality control.

This study converts the piecemeal data on MPBF part qualification methods into interesting information and presents it in tabular form under each strategy. This tabular information provides the basis for further quality improvement efforts in the MPBF process.

This study references researchers and practitioners on recent quality control efforts and their significant findings for a better quality of MPBF part.

This paper aims to consolidate the results of various researchers focusing the different applications, so that this paper could become the torch bearer for the futuristic researchers working in the domain of cold gas dynamics spray coating.

A study on the cold spray coating is presented by summarizing the data present in literature. Important factors such as coating temperature, pressure, coating thickness, particle size, which affect the erosion-corrosion (E-C) resistance, physical and mechanical properties of boiler steel are stated. This paper also addresses the use of cold spray coating and compares it with other different thermal spray processes.

From the literature review, it was noticed that cold spray technology is best as compare to other thermal spray processes to reduce porosity, increase hardness, adhesion strength and retention in properties of feedstock powders.

Cold spray coating technology has a great potential in almost every field especially in restoration of surfaces, generation of complex surface, biomedical application, resist hot corrosion, wear, oxidation and erosion corrosion.

The purpose of this paper is to outline the development, piloting and evaluation of the Who’s Challenging Who? (WCW) training intervention for social care staff to improve their empathy and attitudes towards people with learning disabilities (LD) and challenging behaviour (CB).

A phased approach was taken to the development and testing of the intervention. Initially, the existing literature was reviewed, the theoretical background of the intervention was developed, and then the intervention was designed. A pilot study was undertaken, followed by further development, and a large-scale randomised controlled trial (RCT).

WCW had a small positive effect on staff empathy 20 weeks after the intervention, and small to moderate effects for other staff reported outcomes (e.g. positive empowerment attitudes and positive work motivation). Being trained by people with LD and CB encouraged staff to reflect on the impact they have on the people they support. The trainers with LD valued their role, and saw benefits beyond this (e.g. friendships).

It is possible to carry out high-quality RCT evaluations of social care practice, and research should continue to generate evidence in this way, as in healthcare settings. However, there were difficulties in retaining participants.

People with LD can be actively involved in the co-production and delivery of social care training.

Employment and a fair wage can increase the confidence and empowerment of people with LD.

This is the first large-scale RCT of an intervention that aimed to improve empathy/change attitudes in social care staff who work with people with LD and CB.

The purpose of this paper is to do a thorough literature review to assess the current status of corporate sustainability practices, issues and challenges in small and medium-sized enterprises (SMEs) and, based on literature, suggest a model that can improve and strategically manage their sustainability practices in the emerging market context of Asia.

The authors did a meta-analysis of the reviewed literature taken from peer-reviewed scholarly journals in the time frame of 1985-2016. Methodology used by the authors is through preferred reporting items for systematic reviews and meta-analysis.

Corporate sustainability is a well-practiced area in big organisations. However, literature suggests that in case of SMEs, the situation is different. Social and environmental practices are grossly neglected in SMEs, more specifically in emerging markets. Existing literature mentions that collaborative mode of operation, government policy and facilitation and supporting organisation culture can positively influence SME’s sustainability performance and hence improve their financial performance.

Most of the papers in corporate sustainability literature are qualitative in nature and there is no empirical evidence of establishing this relationship in SME context. This paper tries to conceptualise the existence of a possible framework relating factors of sustainability and their role in improving business performance of the SMEs. However, the findings are purely literature-based and piloting of the questionnaire is also done on 20 SMEs in a specific geography. This is a very small and also a biased sample. Future research studies based on this paper are expected to verify the proposed relationship with larger data set catering to different industry clusters and countries.

The proposed model is only directional in nature. With the content analysis, the authors have tried to answer the research questions relating to factors of sustainability and its impact on business performance. To address the research questions in a more generalised way, an empirical research needs to be conducted to establish the research propositions. The proposed model needs to be validated and optimised with further research and data analysis. Once such a model is established, this can be proved beneficial for providing guidance to SMEs to enhance the sustainability of their business operations.

The SME sector has made a significant contribution to the economic development in countries, and this sector has huge potential for growth, and their geographic spread and penetration is much higher than large organisations. Sustainable growth of this industry sector can reasonably be expected to lead to stable and sustainable development of the nation. Moreover, environmental and social best practices adopted by SMEs will also have a positive influence on society and environment in the long run.

This paper had done a geography wise analysis of sustainable practices in SMEs, and based on the recommendations and suggestions of different analyses, the authors developed few research propositions and also presented a conceptual model. Finally, to address the gap, it mentions some future research possibilities to test and validate the proposed model in the context of SMEs in emerging markets of Asia.
