Social participation and self-reported health in China: evidence from Chinese middle-aged and elderly adults
Authors: Xinxin MA. 
Published: November 2020

PurposeSocial participation (SP) has been shown to have a favorable impact on health status, particularly among elders in developed countries. However, empirical study is scarce for China. This study explores the relation between social participation (SP) and health status among middle-aged adults and elders in China when controlled socioeconomic characteristics of individuals.Design/methodology/approachThis paper employs an empirical study based on the data from a three-wave national longitudinal survey: the Chinese Health and Retirement Longitudinal Study (CHARLS) from 2011, 2013 to 2015. It collects data from 28,895 individuals aged 45–84. It uses lagged variable method (LV) to address the reverse causality problem, and the random-effects model or fixed-effect model to address the heterogeneity problem.FindingsThe paper finds the social participation positively affect self-reported health statistically. The influence of social participation on self-reported health flows through two channels: the improved mental health effect (SP-MH-SRH channel) and the increased income effect (SP-income-SRH channel). In comparison with the SAP-income-SRH channel, the influence of the SP-MH-SRH channel l is greater.Research limitations/implicationsFirst, the absence of other measures of volunteering, such as hours of social participation that are not available in the employed dataset. Second, even though the LV model and FE model are used in the paper, there may remain the endogeneity problem in the results. Third, the influences of formal and informal social participation should be distinguished in the future research.Social implicationsSocial participation may improve the self-reported health status. The influence of SP on health may be due to the improved mental health effect (SP-MH-SRH channel). In order to improve the mental and physical health status of middle-aged adults and elders the government should consider even more promotion of social participation.Originality/valueFirst, this paper focuses on the correlation between social participation and well-being (self-reported health) of middle-aged adults and elderly in China, the previous studies on the issue for China are scarce. Second, this paper uses the lagged variable method (LV) to address the reverse causal relation problem, and the fixed-effects model or the random-effects model to address the heterogeneity problem. Third, the two channels (the improved mental health effect and the increased income effect) are firstly investigated in this study.

Published: November 2020

Purpose
The purpose of this paper is to show the importance of validity process in survey questionnaire instrument development. It is to confirm all items chosen are valid in the context of study, especially in assessing municipal website Web user behaviours. The quality of measurement also can be assured.

Design/methodology/approach
Several methods used to assess validity of the survey instrument in this study, such as face validity, content validity index (CVI) and construct validity. CVI assessment is widely used to examine each item in the survey instrument exact measures what is supposed to be measured. Prolific items used to evaluate web aesthetic, usability, navigation, content organization, interactivity and user engagement.

Findings
Several items were rephrased and simplified during face validity assessment, while three items from user engagement construct were excluded after the CVI assessment. Reliability and redundancy analysis had shown good results for each item and construct for both dependent and independent variables. None of the items in any construct need to be eliminated.

Research limitations/implications
The face validity, content validity and construct validity assessments are sufficient to assure the consistency of the conceptual framework, the content of items and overall measurement approach reflecting the setting or context of study which are web users.

Practical implications
The validated survey instrument provides practical guidelines for government municipal website owners on how to stimulate website user to keep engaged on the government municipal website. Identified website content that acts as credibility cues can be as object attention when planning the strategy of Web content management. Through proper design and attracting touch up, the credibility cues can attract website user and force the user to engage deeper on the government municipal website content, believe it as the main source of information and recognize it as authoritative organization.

Originality/value
The measurement model of this study that consists of formative construct of surface credibility, and user engagement is proposed to be tested in a different context of this study.

Published: November 2020

PurposeAn appropriate equivalent model is the key to the effective analysis of the system and structure in which permanent magnet takes part. At present, there are several equivalent models for calculating the interacting magnetic force between permanent magnets including magnetizing current, magnetic charge and magnetic dipole–dipole model. How to choose the most appropriate and efficient model still needs further discussion.Design/methodology/approachThis paper chooses cuboid, cylindrical and spherical permanent magnets as calculating objects to investigate the detailed calculation procedures based on three equivalent models, magnetizing current, magnetic charge and magnetic dipole–dipole model. By comparing the accuracies of those models with experiment measurement, the applicability of three equivalent models for describing permanent magnets with different shapes is analyzed.FindingsSimilar calculation accuracies of the equivalent magnetizing current model and magnetic charge model are verified by comparison between simulation and experiment results. However, the magnetic dipole–dipole model can only accurately calculate for spherical magnet instead of other nonellipsoid magnets, because dipole model cannot describe the specific characteristics of magnet's shape, only sphere can be treated as the topological form of a dipole, namely a filled dot.Originality/valueThis work provides reference basis for choosing a proper model to calculate magnetic force in the design of electromechanical structures with permanent magnets. The applicability of different equivalent models describing permanent magnets with different shapes is discussed and the equivalence between the models is also analyzed.

Managing carbon footprint for a sustainable supply chain: a systematic literature review
Authors: Ghosh Piya , Jha Ajay , Sharma RRK 
Published: November 2020

PurposeThe carbon emissions due to industrial production and market consumption activities are the major contributors to global warming. With the signing of UN Paris Accord 2016 on climate change, the world's major countries are devising measures to combat climate change and attain a sustainable, low-carbon future. Globalization demands companies not only to adopt greener manufacturing practices internally for reduced carbon footprint (CFP) but beyond its boundaries (i.e. its supply chain). This study aims to discuss the relationship between CFP and sustainable supply chain, as evident in the current literature and industry practices. It provides a total comprehension of past, present and future headings in the CFP area and its contribution to a sustainable supply chain.Design/methodology/approachA systematic literature review and analysis have been undertaken in supply chain sustainability and CFP. A bibliometric approach is adopted for this investigation, and one of the biggest computerized databases, “Scopus,” has been picked. In total, 37 articles have been zeroed in after a careful and watchful screening of firmly related topics.FindingsMost researchers gave predominance to environmental impact among the three pillars of sustainability (economy, society and the environment) for a sustainable supply chain environment. Only a few researchers were motivated to cover social development and social responsibility aspects. This review highlights how managing a CFP is one of the significant attributes of sustainable development. Existing literature in the field of CFP and sustainability have been written on actual industry cases. Food, electricity and energy are some significant industries where supply chain sustainability successfully reduces carbon emission.Originality/valueThe theory-building strategy with recommendations on the conceptualization of a sustainable supply chain is limited in the literature. This study gives broad ideas on how organizations modified and redeveloped different tools and technologies to make their supply chain more sustainable. The strategic role of different carbon policies, environmental rules and regulations in the domain of CFP is also recognized in this work. This study highlights the biases of most of the researches toward applications than policy interventions. This study discusses the theoretical perspective about how CFP affects supply chain management and helps organizations and researchers develop a new set of approaches in handling CFP and other sustainability aspects.

Authors: Rana Bharti , Chakraborty J.N. 
Published: November 2020

PurposeThis paper aims to study the ability of laccase for decolourisation of reactive dyes in presence and absence of natural and synthetic mediators.Design/methodology/approachBox–Behnken design was used to optimize the parameters to achieve optimum response value. Preliminary screening using several mediators was performed to evaluate extent of decolourisation for the purpose followed by selection of effective mediators only.FindingsLaccase performs in acidic pH; increase in temperature enhances its activity. Rate of decolourisation depends on laccase and dye concentration, temperature, pH and treatment time. Out of five mediators studied, HBT, BT and VA showed promising results.Research limitations/implicationsStudy on decolourisation was conducted for individual dyes. In some cases, dyes are applied in combination which requires further study for authentication of data.Practical implicationsDecolourisation with laccase has been found to be a promising technology in waste water treatment. However, selection of mediator remains a crucial factor.Social implicationsReactive dyes are self-hydrolysed over time under natural conditions and extent of decolourisation depends on concentration of dye discharged and time spent. If not decolourised quickly, it imposes restriction on use of river water for irrigation.Originality/valueIn this work, activity of various natural and synthetic mediators alongwith laccase was studied to achieve maximum decolourisation which was not studied earlier.
Study on fabric compression under seam vis a vis quantitative measurement of seam boldness and thread consumption for lockstitch 301
Authors: Chavhan Md Vaseem , Naidu Mandapati Ramesh 
Published: November 2020

Purpose
This paper aims to develop at sewing thread during the seam formation may lead to the compression of fabric under seam. In the present study, the model has been proposed to predict the seam compression and calculation of seam boldness, as well as thread consumption by considering seam compression.

Design/methodology/approach
The effect of sewing parameters on the fabric compression at the seam (Cf) for fabrics of varying bulk density was studied by the Taguchi method and also the multilinear regression equation is obtained to predict seam compression by considering these parameters. The framework has been set as per the single view metrology approach to measuring structural seam boldness (Bs). One of the basic geometrical models (Ghosh and Chavhan, 2014) for the prediction of thread consumption at lock stitch has been modified by considering fabric compression at the seam (Cf).

Findings
The multilinear regression model has been proposed which can predict the compression under seam using easily measurable fabric parameters and stitch density. The seam boldness is successfully calculated quantitatively using the proposed formula with a good correlation with the seam boldness rated subjectively. The thread consumption estimation from the proposed approach was found to be more accurate.

Originality/value
The compression under seam is found out using easily measurable parameters; fabric thickness, fabric weight and stitch density from the proposed model. The attempt has been made to calculate seam boldness quantitatively and the new approach to find out thread consumption by considering the seam compression has been proposed.
Videography – studying ethical uncertainty in alternative entrepreneurship
Authors: Skoglund Annika , Redmalm David , Berglund Karin 
Published: November 2020

Purpose
The purpose of this paper is to develop videographic methods for the study of alternative entrepreneurship, with a theoretical focus on “ethical uncertainties”, exemplified in this paper by the exploration of evolving actions and unpredictable outcomes in a specific case, the Hungarian company Prezi.

Design/methodology/approach
By first situating Prezi’s alternative entrepreneurship in the turbulent Hungarian political context and situation for the Roma population, this study presents how the methodological foundations of organizational videography have affirmed aesthetic immersion, which is of particular use for the study of ethical uncertainty.

Findings
Following a methodological exploration of the specific research design and ethnographic reflections on three ways in which ethical uncertainties arise, this study discusses the videographic possibilities to study something as elusive as ethical uncertainty and its link to alternative futures.

Originality/value
The political context in Hungary poses many challenges for organizations that attempt to “do good” and create alternative futures. This paper explains how this political context permeates Prezi’s entrepreneurship and research thereof, by highlighting “ethical uncertainty”. The combined contribution (paper and videography) invites the reader to think differently about the authority of research, become a viewer and reflect on their own experiences of ethical uncertainty in alternative entrepreneurship.
Is the interest rate setting behaviour of the Bank of Ghana constrained by high debt levels?
Authors: Iddrisu Abdul‐Aziz , Alagidede Imhotep Paul 
Published: November 2020

AbstractWhile assertions of debt constraints on monetary policy have been documented in the literature, empirical investigation into this phenomenon remains egregiously limited, with the only study using the Generalized Method of Moments that fails to provide confidence intervals for the threshold estimate. We examine whether or not high debt levels constrain the interest rate setting behaviour of the Bank of Ghana, with the aid of sample splitting and a threshold estimation technique that overcomes the weaknesses of previous studies. We find that monetary policy response to inflation gap in the high debt regime (above the debt to gross domestic product [GDP] threshold of 35.1%) is woefully disproportionate, a key indication of debt constraint and inflation accommodation by a central bank that is supposed to be targeting inflation. Important policy recommendations are proffered.

Published: November 2020

BackgroundAlcohol misuse continues to be a significant public health problem. Understanding the factors that may contribute to the harmful progression in drinking is an important aspect of public health. Previous research has shown that affect regulation is associated with problematic alcohol use. Additionally, emotion instability has been found as a predictor of alcohol‐related problems and may be linked to reinforcement mechanisms.MethodsThe current study examined positive mood, negative mood, and mood instability in real time across drinking and nondrinking days utilizing ecological momentary assessment (EMA). Current drinkers (n = 74) were recruited for a 21‐day EMA study. Participants completed up to 10 random assessments of positive mood, negative mood, and alcohol use per day. Mood instability was assessed as the squared difference in current mood from mood in the previous assessment. Data were analyzed using piecewise multilevel regression to examine mood trajectories across drinking and nondrinking days.ResultsPositive emotion across the day was higher on drinking days than nondrinking days and continued to increase after drinking initiation. In contrast, negative emotion across the day was lower on drinking days than nondrinking days and continued to decrease after drinking initiation. Emotional functioning was stable across the day on nondrinking days. However, on drinking days there was a steady increase in emotional instability leading up to drinking initiation, followed by a rapid stabilization after initiation.ConclusionsThis study highlights the potentially reinforcing impact of alcohol via emotional stability. Overall, these findings highlight the importance of mood dynamics when examining the reinforcing effects of alcohol consumption.
School Cultural Socialization and Academic Performance: Examining Ethnic‐Racial Identity Development as a Mediator Among African American Adolescents
Authors: Del Toro Juan , Wang Ming‐Te 
Published: November 2020

Historic racial disparities in the United States have created an urgent need for evidence‐based strategies promoting African American students’ academic performance via school‐based ethnic‐racial socialization and identity development. However, the temporal order among socialization, identity, and academic performance remains unclear in extant literature. This longitudinal study examined whether school cultural socialization predicted 961 African American adolescents’ grade point averages through their ethnic‐racial identities (49.6% males; Mage = 13.60; 91.9% qualified for free lunch). Results revealed that youth who perceived more school cultural socialization had better grades 1 and 2 years later. In addition, identity commitment (but not exploration) fully mediated these relations. Implications for how educators can help adolescents of color succeed in schools are discussed.
A hyperacute immune map of ischaemic stroke patients reveals alterations to circulating innate and adaptive cells

Published: November 2020

Summary
Systemic immune changes following ischaemic stroke are associated with increased susceptibility to infection and poor patient outcome due to their role in exacerbating the ischaemic injury and long-term disability. Alterations to the abundance or function of almost all components of the immune system post-stroke have been identified, including lymphocytes, monocytes and granulocytes. However, subsequent infections have often confounded the identification of stroke-specific effects. Global understanding of very early changes to systemic immunity is critical to identify immune targets to improve clinical outcome. To this end, we performed a small, prospective, observational study in stroke patients with immunophenotyping at a hyperacute time point (&lt; 3 h) to explore early changes to circulating immune cells. We report, for the first time, decreased frequencies of type 1 conventional dendritic cells (cDC1), haematopoietic stem and progenitor cells (HSPCs), unswitched memory B cells and terminally differentiated effector memory T cells re-expressing CD45RA (TEMRA). We also observed concomitant alterations to human leucocyte antigen D-related (HLA-DR), CD64 and CD14 expression in distinct myeloid subsets and a rapid activation of CD4+ T cells based on CD69 expression. The CD69+CD4+ T cell phenotype inversely correlated with stroke severity and was associated with naive and central memory T (TCM) cells. Our findings highlight early changes in both the innate and adaptive immune compartments for further investigation as they could have implications the development of post-stroke infection and poorer patient outcomes.

Summary
Biological treatments such as enzyme-replacement therapies (ERT) can generate anti-drug antibodies (ADA), which may reduce drug efficacy and impact patient safety and consequently led to research to mitigate ADA responses. Transient low-dose methotrexate (TLD-MTX) as a prophylactic ITI regimen, when administered concurrently with ERT, induces long-lived reduction of ADA to recombinant human alglucosidase alfa (rhGAA) in mice. In current clinical practice, a prophylactic ITI protocol that includes TLD-MTX, rituximab and intravenous immunoglobulin (optional), successfully induced lasting control of ADA to rhGAA in high-risk, cross-reactive immunological material (CRIM)-negative infantile-onset Pompe disease (IOPD) patients. More recently, evaluation of TLD-MTX demonstrated benefit in CRIM-positive IOPD patients. To more clearly understand the mechanism for the effectiveness of TLD-MTX, non-targeted transcriptional and proteomic screens were conducted and revealed up-regulation of erythropoiesis signatures. Confirmatory studies showed transiently larger spleens by weight, increased spleen cellularity and that following an initial reduction of mature red blood cells (RBCs) in the bone marrow and blood, a significant expansion of Ter-119+CD71+ immature RBCs was observed in spleen and blood of mice. Histology sections revealed increased nucleated cells, including hematopoietic precursors, in the splenic red pulp of these mice. This study demonstrated that TLD-MTX induced a transient reduction of mature RBCs in the blood and immature RBCs in the bone marrow followed by significant enrichment of immature, nucleated RBCs in the spleen and blood during the time of immune tolerance induction, which suggested modulation of erythropoiesis may be associated with the induction of immune tolerance to rhGAA.
