Wire + arc additive manufacturing (WAAM) uses existing welding technology to make a part from metal deposited in an almost net shape. WAAM is flexible in that it can use multiple materials successively or simultaneously during the manufacturing of a single component.

In this work, a gas metal arc welding (GMAW) based wire + arc additive manufacturing (WAAM) system has been developed to use two material successively and fabricate bimetallic additively manufactured structure (BAMS) of low carbon steel and AISI 316L stainless steel (SS).

The interface shows two distinctive zones of LCS and SS deposits without any weld defects. The hardness profile shows a sudden increase of hardness at the interface, which is attributed to the migration of chromium from the SS. The tensile test results show that the bimetallic specimens failed at the LCS side, as LCS has lower strength of the materials used.

The microstructural features and mechanical properties are studied in-depth with special emphasis on the bimetallic interface.

The purpose of this paper is to investigate the extent of voluntary disclosures in UK higher education institutions’ (HEIs) annual reports and examine whether internal governance structures influence disclosure in the period following major reform and funding constraints.

The authors adopt a modified version of Coy and Dixon’s (2004) public accountability index, referred to in this paper as a public accountability and transparency index (PATI), to measure the extent of voluntary disclosures in 130 UK HEIs’ annual reports. Informed by a multi-theoretical framework drawn from public accountability, legitimacy, resource dependence and stakeholder perspectives, the authors propose that the characteristics of governing and executive structures in UK universities influence the extent of their voluntary disclosures.

The authors find a large degree of variability in the level of voluntary disclosures by universities and an overall relatively low level of PATI (44 per cent), particularly with regards to the disclosure of teaching/research outcomes. The authors also find that audit committee quality, governing board diversity, governor independence and the presence of a governance committee are associated with the level of disclosure. Finally, the authors find that the interaction between executive team characteristics and governance variables enhances the level of voluntary disclosures, thereby providing support for the continued relevance of a “shared” leadership in the HEIs’ sector towards enhancing accountability and transparency in HEIs.

In spite of significant funding cuts, regulatory reforms and competitive challenges, the level of voluntary disclosure by UK HEIs remains low. Whilst the role of selected governance mechanisms and “shared leadership” in improving disclosure, is asserted, the varying level and selective basis of the disclosures across the surveyed HEIs suggest that the public accountability motive is weaker relative to the other motives underpinned by stakeholder, legitimacy and resource dependence perspectives.

This is the first study which explores the association between HEI governance structures, managerial characteristics and the level of disclosure in UK HEIs.

The purpose of this paper is to focus on the formation of service perceptions in services that are stressful and unpleasant for customers, e.g. healthcare services. The authors set out to show that customers' happiness, here conceptualized as a stable perception of happiness one has towards one's life, predicts how customers manage adverse services.

The authors conducted a survey in a healthcare setting and analyzed the data with partial least square modeling.

The results show that happiness is indirectly linked, through mood, to perceived service quality, trust and service outcome. Thus, the results suggest that happy consumers are less vulnerable to distress in adverse services.

The findings indicate that, to enable service providers to offer adequate support in adverse service situations, service management would benefit from taking into account different customers' different levels of happiness. It is recommended that providers of adverse services segment their customer base according to the level of happiness and allocate resources to foster trust and expectations to less happy customers that would benefit from more support.

The paper contributes to the service literature by providing an understanding of how service perceptions are formed in adverse service situations. As happiness is relatively stable across time and situations, this study also contributes to understanding the role of personality traits on evaluation.

In most countries, HIV and AIDS rates are higher among inmates than in the general population. As part of a series of studies aimed at examining the plausible links between HIV and incarceration in a State prison system in the United States (US), the present study examined pre‐incarceration sexual and injection drug use behaviours of inmates and their demographic correlates. Two‐hundred‐andsixteen female and 260 male inmates randomly selected from 17 Illinois State prisons completed a structured questionnaire. Findings indicate that the rate of inconsistent condom use with multiple anal and vaginal sexual partners among study participants ranged from 11 to 49%. Fourteen per cent of the women and 25% of the men reported ever injecting drugs, while 13% of the women and 7% of the men had ever shared needles. Demographic correlates of risk behaviours differed between gender and for specific behaviours. The findings indicate that persons entering prison generally exhibit risk behaviours that may increase their chances of acquiring HIV. Comprehensive HIV prevention programmes should be made available to inmates in US prisons and be accessible to them upon release. Studies are needed to examine how individual and structural factors interact to increase HIV and incarceration risk.

Two distinct literatures have investigated the impact of negotiator frames. Both literatures demonstrate that negotiator frames significantly influence both bargaining behavior and negotiated outcomes. These two literatures, however, offer completely different conceptualizations of what negotiator frames actually are. In this article we classify these two conceptualizations as reference frames, the referent‐dependent perception of outcomes, and conflict frames, a multi‐dimensional orientation toward conflict. We report results from an experiment that links these two types of frames. We find that loss‐framed negotiators adopt conflict frames that are more win‐oriented and task‐oriented than the conflict frames gain‐framed negotiators adopt. Our results offer insight into the frame adoption process and have implications for dispute resolution and negotiation practice.

The purpose of this paper is to redefine the concept of organizational sustainability by assimilating corporate spirituality into the concept of the triple bottom line (TBL).

This paper is a conceptual paper which presents a newly coined concept for sustainable organizations as a result of a literature study on management and psychology fields. This study explores the concept of competitive advantage, research-based view (RBV) theory, spiritual leadership theory (SLT), positive environmental psychology (PEP) and human resource development (HRD) to fill the void of “soul” as an element in TBL, which is seen as a barrier that prevents organizations from being more holistically sustainable.

The paper provides new insights into the redefinition of organizational sustainability by introducing quadruple bottom line (QBL), effectively a combination of management and psychological disciplines. This paper also proposes measurements of corporate spirituality, adapted from well-established mental health research, which have been used in the Diagnostic and Statistical Manual of Mental Disorders as well.

Researchers are encouraged to test the proposed concept further.

The paper includes implications for the development of sustainable organizations by offering CEOs and managers corporate spirituality support with which they can make wise decisions when considering environmental, societal and economic perspectives in their operations.

The QBL concept promises to contribute significantly to the growth of more comprehensive, holistic and sustainable organizations, as well as to extend the current literature on organizational sustainability.

SMEs that manage more sustainability focused initiatives into their core business strategy can possibly benefit from lower expenses, reduced threats and new business opportunities, but in Malaysia most of the SMEs are still far off in terms of adapting to a sustainable business growth outline from a holistic point of view. Hence, this study aims to serve deeper understanding about a strategic innovation focused sustainable growth model on basis of multidisciplinary QBL-QHIM theoretical perspectives where strategic innovation practices intervene in between desired growth and government support (regulations).

This conceptual investigation embraces a newly emerged concern of sustainable business growth in SMEs, considering ranges of literature reviews from the disciplines of management and entrepreneurship. The study also systematically explores the concepts of regulations, strategic innovation practices on basis of QBL and QHIM theories to adjust the sustainable business growth model from a holistic angle.

The outcomes show that multidisciplinary QBL-QHIM conjunction within the interrelationships of the selected constructs holds the potential for innovation focused business growth in a more sustainable, comprehensive and holistic manner. The study also detects that exploitative-explorative innovation practices can possibly mediate in between suitable regulations and sustainable business growth of SMEs, considering supportive external environment.

Researches are encouraged to test the proposed model.

The study indicates a conceptual configuration for policy makers as well as entrepreneurs to ensure sustainable business growth for SMEs. The outcomes of the study also provide useful direction on decision-making process of owner or manager considering social, economic, environmental and spiritual aspects of daily operations.

The conceptual model may possibly able to generate more social values, considering a holistic angle into business activities.

The conceptualization is a unique attempt, considering developing regions to extend the current understanding of strategic innovation focused sustainable growth process of SMEs from a holistic angle.

The purpose of this article is to investigate the overconfidence effect on investor attitude towards new ventures investment valuation as a function of the investor involvement in estimating the venture's success probability.

The method used was experimental; econometric analysis within a prospect theory framework.

Participants in the role of investors are more risk seeking when they are called upon to judge success probability relative to them being offered a (reliable) success probability even when their own judgement is based on a restricted data set. Further, that investor overconfidence is a consequence of changes in risk attitude, not probability weighting.

Opens up a number of issues relating to investor‐entrepreneur opportunity perception disparity and its impact on the “investment‐gap”. Considers factors that might be explored experimentally, including task confidence, investor‐entrepreneur information asymmetry and source credibility. Detailed comment made on future research directions.

Impacts on the management of communication between entrepreneurs and investors. Six management variables that might influence disparities in investor‐entrepreneur risk assessment considered in relation to findings.

My goal is to describe my life in marketing over more than 36 years and to help readers better understand (from my personal perspective) the history of marketing. I also aim to lift the curtain on some aspects of service within the marketing community.

This paper is an autobiographical sketch. It describes some key moments in my career, as well as describing how my most cited articles came to be written. It emphasizes the contextual factors at work in different periods, so readers can better understand how and why my research evolved in certain ways. I aim to convey the nature and variety of career experiences that were (and are) open to marketing academics. I discuss my experiences at the Journal of Marketing and the Marketing Science Institute.

Marketing changed rapidly between 1974 and 2017. Although change can be uncomfortable, I urge marketers to seek exposure to new ideas and practices; they are essential to learning and growth. Unexpected opportunities will come along and an alert individual can learn much from them. My time in industry was a learning experience for me. There are many kinds of interesting and successful careers.

The marketing field advances, not by the work of a single individual, but from the accumulated work of the entire marketing community. Everyone has a role to play. I encourage each individual to look for ways to contribute. I offer thoughts on how to build a research career based on my own experience.

My thoughts may shed some light on the experiences of a woman academic and the globalization of marketing academia between 1974 and 2017.

My hope is that this paper contributes to a better understanding of the history of marketing, when it is considered together with other articles on this topic. It may also be useful to people who are embarking upon a career, as well as those seeking to understand the work of earlier marketing scholars.

Coronavirus disease-2019 (COVID-19) is becoming a crucial health problem worldwide. Continued and high-speed mutations of this virus result in the appearance of new manifestations, making the control of this disease difficult. It has been shown that well-nourished patients have strong immune systems who mostly have short-term hospitalization compared to others. The purpose of this study is to review the major nutrients involved in the immune system reinforcement and to explain nutritional aspects during the recovery of COVID-19.

In this review paper, the mechanistic role of nutrients in boosting the immune system and the nutritional aspects during the recovery of COVID-19 patients were discussed. Papers indexed in scientific databases were searched using antioxidants, COVID-19, inflammation, immune system, macronutrient, micronutrient and probiotic as keywords from 2000 to 2022.

Because of the adverse effects of drugs like thrombosis, pulmonary embolism and hypercholesterolemia, a balanced diet with enough concentrations of energy and macronutrients could increase the patient's durability. The inflammatory cytokines in a vicious cycle delay patients’ rehabilitation. The main mechanistic roles of micronutrients are attributed to the downregulation of virus replication and are involved in energy homeostasis. Dysbiosis is defined as another disturbance among COVID-19 patients, and supplementation with beneficial strains of probiotics helps to exert anti-inflammatory effects in this regard. Being on a well-planned diet with anti-inflammatory properties could reverse cytokine storms as the major feature of COVID-19. Future studies are needed to determine the safe and effective dose of dietary factors to control the COVID-19 patients.
