The main purpose of this paper is to present what the Industry 5.0 phenomenon means in the supply chain context. A systematic literature review method was used to get evidence from the current knowledge linked to this theme. The results have evidenced a strong gap related to Industry 5.0 approaches for the supply chain field. Forty-one (41) publications, including conference and journal papers, have been found in the literature. Nineteen (19) words, which were grouped in four (4) clusters, have been identified in the data analysis. This was the basis to form the four (4) constructs of Industry 5.0: Industry Strategy, Innovation and Technologies, Society and Sustainability, and Transition Issues. Then, an alignment with the supply chain context was proposed, being the basis for the incipient Supply Chain 5.0 framework and its research agenda. Industry 5.0 is still in an embryonic and ideal stage. The literature is scarce and many other concepts and discoveries are going to emerge. Although this literature review is based on few available sources, it provides insightful and novel concepts related to Industry 5.0 in the supply chain context. Moreover, it presents a clear set of constructs and a structured research agenda to encourage researchers in deploying further conceptual and empirical works linked to the subject herein explored. Organizations’ leadership, policymakers, and other practitioners involved in supply chains, and mainly those currently working with Industry 4.0 initiatives, can benefit from this research by having clear guidance regarding the dimensions needed to structurally design and implement an Industry 5.0 strategy. This article adds valuable insights to researchers and practitioners, by approaching the newest and revolutionary concept of the Industry 5.0 phenomenon in the supply chain context, which is still an unexplored theme.

Purpose The purpose of the paper is to present the latest scholarly trends in the field of social capital in libraries, to review research concepts published by LIS professionals and to suggest further research possibilities in this area. Design/methodology/approach This paper presents a review and critical analysis of literature associated with research on social capital in libraries to highlight its importance for the development of LIS and its impact on the functioning of environments linked with various types of libraries. The goal of literature analysis was to determine the current condition of research on social capital in libraries. The main trends were identified and the need for further qualitative analyses, which are missing at the moment, was confirmed. Findings It was determined that, so far, LIS professionals have focussed mainly on the role of municipal libraries in developing social capital, the problem of building trust, especially in immigrant circles and the impact of libraries on promoting a civil society. Academic libraries, rural libraries, organisational capital in libraries and individual social capital of librarians were a much less frequent subject of research. The role of libraries in developing social capital in educational (primary and secondary education) and professional (non-university professionals) circles is practically non-existent in research, and it will require in-depth studies and analyses in the coming years. Originality/value This paper constitutes a synthetic review of the latest research concepts concerning social capital in libraries. It identifies the most important research trends and areas that so far have not been explored and suggests research methods to help LIS professionals design future research in this area more effectively.

Composition Structure

Ruminants have adapted to cope with bulky, fibrous forage diets by accommodating a large, diverse microbial population in the reticulo-rumen. Ruminants are dependent on forages as their main sources of energy and other nutrients. Forages are comprised of a complex matrix of cellulose, hemicellulose, protein, minerals and phenolic compounds (including lignin and tannins) with various linkages; many of which are poorly defined. The composition and characteristics of polysaccharides vary greatly among forages and plant cell walls. Plant cell walls are linked and packed together in tight configurations to resist degradation, and hence their nutritional value to animals varies considerably, depending on composition, structure and degradability. An understanding of the inter-relationship between the chemical composition and the degradation of plant cell walls by rumen microorganisms is of major economic importance to ruminant production. Increasing the efficiency of fibre degradation in the rumen has been the subject of extensive research for many decades. This review summarises current knowledge of forage chemistry in order to develop strategies to increase efficiency of forage utilisation by ruminants.

Military Combat

This paper describes a framework for understanding military combat mental health based on the possible mental ill-health consequences of exposure to ‘potential trauma events’ for members of the armed forces and after their military service as veterans. It uses a life course approach that maps an individual’s mental well-being against four ‘states’: fit, reacting, injured and ill. It then considers five categories of factors that influence the risk of mental illness from this exposure based on research evidence; prejoining vulnerability, resilience, precipitating, treatment and recovery. This framework offers a structure to debate current knowledge, inform policy and therapeutic interventions, provide education and to guide future research into the subject.

The Brain

Over the past 20 years, psychoneuroimmunological research has produced a large body of evidence that challenges the historically dominant view that the immune system operates in an autonomous manner independent of other physiological systems. Today, there is little doubt that the brain and the immune system are intimately linked and capable of reciprocal communication (Ader et al. 1991). Despite the acknowledged bi-directional nature of the brain–immune system connection, the predominant focus of study has been on the effects of psychological and behavioural events (e.g. stress) on immune responses and disease processes, and the mechanisms underlying such effects (see Kusnekov & Rabin, 1994; Maier et al. 1994; Rozlog et al. 1999). However, considerable interest in the possibilities of immune-system-to-brain communication was initiated by a seminal paper considering the biological basis of behaviour in sick animals (Hart, 1988). Subsequently, the immunological determinants of the behavioural, cognitive and emotional changes associated with acute illness, as well as with more chronic psychopathological states (e.g. depression) have become the subject of rapidly expanding areas of research (e.g. Kent et al. 1992; Lloyd et al. 1992; Hickie & Lloyd, 1995; Maes et al. 1995a; Rothwell & Hopkins, 1995; Dantzer et al. 1996; Maier & Watkins, 1998; Vollmer-Conna et al. 1998; Maes, 1999).The main objective of this editorial is to provide a succinct overview of current knowledge of the normal behavioural correlates of acute infective illness, their adaptive function and underlying mechanisms. Elucidation of the processes involved in the appearance, maintenance and inhibition of ‘normal’ sickness behaviour is important if extrapolations from this phenomenon to more chronic psychopathological conditions are to provide more than a new label for poorly understood non-specific symptom clusters.

Film Lubrication

With metal-on-metal (MoM) bearings, fluid film lubrication is disrupted when the contact patch area between the femoral head and the cup is close to the edge of the acetabular component, making the calculation of the contact patch to rim (CPR) distance a key variable in the study of the performance of MoM bearings. A few research centers have used models of varying complexity to calculate the CPR distance and determine its relationship with assessments of component wear. In this review, we aimed to summarise the current knowledge related to the application of CPR distance calculations in the study of in vivo performance of MoM bearings. Our systematic search of the US National Library of Medicine yielded 9 relevant publications in which 3 different models were used for the computation of the CPR distance. The 3 models show different levels of complexity and their use is mainly dependent upon the size of the subject sample and the nature of the data collected as a dependent variable. The studies reviewed consistently showed a strong inverse correlation between CPR distance and wear or metal ion levels suggesting that any study aiming to determine the risk factors for MoM hip devices needs to include an assessment of CPR distance. Cup anteversion can be measured reliably with various tools and should not be an obstacle to the use of this essential variable that is CPR distance.
