Combining Ancient DNA and Radiocarbon Dating Data to Increase Chronological Precision
Authors: Sedig Jakob W. , Olade Iñigo , Patterson Nick , Reich David 
Published: September 2020

AbstractThis paper examines how ancient DNA data can enhance radiocarbon dating. Because there is a limit to the number of years that can separate the dates of death of related individuals, the ability to identify first-, second-, and third-degree relatives through aDNA analysis can serve as a constraint on radiocarbon date range estimates. To determine the number of years that can separate related individuals, we modeled maximums derived from biological extremes of human reproduction and death ages and compiled data from historic and genealogical death records. We used these estimates to evaluate the date ranges of a global dataset of individuals that have been radiocarbon dated and for which ancient DNA analysis identified at least one relative. We found that many of these individuals could have their date ranges reduced by building in date of death separation constraints. We examined possible reasons for date discrepancies of related individuals, such as dating of different skeletal elements or wiggles in the radiocarbon curve. Our research demonstrates that when combined, radiocarbon dating and ancient DNA analysis can provide a refined and richer view of the past.
Smartphone use and travel companions' relationship
Authors: Tan Wee Kheng , Lu Kuan-Ju 
Published: September 2020

PurposeThe impact of smartphone use at tourist destinations on the relationship of travel companions and trip satisfaction remains unclear. This study considers differences in relational outcomes arising from smartphone use to kill time and reduce boredom during leisure travel with different companions, either family or friends, and uses the Riva's emotion regulation model to examine whether such smartphone use provides immediate relief from ostracism.Design/methodology/approachPartial least square (PLS) method and PLS multigroup analysis were used to analyze the data collected from 205 Taiwanese tourists (104 respondents vacationing with friends and 101 respondents with family).FindingsThis study found no negative effect of smartphone use to kill time and reduce boredom on relationship satisfaction and overall trip satisfaction. Smartphone use is rather limited as a contributor to trip satisfaction, and the effect of smartphone use depends on who the tourists are traveling with. The results reflect the effect of the established position of smartphones in everyday life, extending to tourism. The use of smartphones to kill time and avoid boredom is not a sufficiently “active” activity to serve as an effective immediate response to ostracism.Originality/valueThis study contributes to the continuing debate on the impact of new technologies on social relations. Although past studies have examined the relational outcomes of smartphone use, few have investigated this subject in the context of different travel companions. Using Riva's emotion regulation model, this study considers smartphone use as a possible response to ostracism.
Integrated capitals reporting and companies' sustainable value: evidence from the Asian continent
Authors: Anifowose Mutalib , Abang Salihin , Zakari Muntaka Alhaji 
Published: September 2020

PurposeThis paper examines the going concern of integrated reporting <IR> as the pessimistic about its sustainable value relevance is gaining momentous. The study employs a quantitative approach to data analysis and mainly sourced secondary data from integrated reports of 83 sampled companies.Design/methodology/approachUtilising data from the companies' integrated reports from 2015 to 2018, the study analyses the impact of <IR> capitals disclosure on corporate sustainable value. <IR> was proxied by its six capital elements, which include financial, manufactured, human, intellectual, natural and social, and relationship capitals, while sustainable value was surrogated by the cost of financing and revenue growth rate. The study develops a checklist and utilises content analysis to score the quality of disclosure by sample companies during the period.FindingsThe longitudinal panel data analysis results reveal that on overall disclosure, <IR> capital has a significant positive effect on the revenue growth but fails to document such on the cost of financing. Meanwhile, on the individual level, human capital and natural capital disclosure have an indirect effect on the cost of financing, while all the six subclassifications affect the revenue growth of the sampled companies.Research limitations/implicationsThe study sampled only 83 companies across the region due to the limited availability of data. Therefore, the generalisation of findings might be hindered, and further examination might be considered as more data become available.Practical implicationsThe study would support the regulators in developing countries to monitor <IR> practices for their domestic companies. It would assist the International Integrated Reporting Council (IIRC) to review the industry's current <IR> practices and give the reason for better <IR> implementation in the future, from both minority and majority economies.Originality/valueThe study is among the pioneer studies that would consider <IR> research across the Asian continent. The study contributes to the recent discussion about sustainable value relevance of <IR>. Also, it would provide some level of incentive to those charged with governance concerning the voluntary compliance with the <IR> framework.
Meat reduction, vegetarianism, or chicken avoidance: US omnivores’ impressions of three meat-restricted diets
Authors: Asher Kathryn E. , Peters Paul 
Published: September 2020

PurposeMeat consumption has a variety of implications in society. While various types of meat-restricted diets exist to address this, not enough is known about how the average meat consumer views different avenues to lessening their intake. In response, this study aims to assess US omnivores’ impressions of three meat-restricted diets.Design/methodology/approachAn online survey was administered to a cross-sectional, census-balanced sample from Nielsen of 30,000+ US adults. Omnivores (N = 928) were randomized into one of the three conditions where they were asked about their perceptions of a vegetarian diet, a reduced-meat diet or a chicken-free diet as individuals not currently following that dietary pattern.FindingsThe findings showed that omnivores had a more favorable perception of a reduced-meat diet on a greater number of study variables as compared to the vegetarian or chicken-free diets. The research also demonstrated that a majority of omnivores were in the precontemplation stage of cognitive change, suggesting that most American omnivores are not actively demonstrating a readiness to alter their meat consumption in the ways presented.Originality/valueThis research is the first to examine the comparative trends around these three diets among omnivores. It also speaks to how the desirability of meat restriction varies by type of approach, i.e. elimination or reduction, and if the latter, what type. The findings may be of relevance for efforts to reduce global meat consumption for ethical, health, or environmental reasons.

Authors: Albayrak Tahir , Güzel Özlem , Caber Meltem , Kılıçarslan Özge , Dursun Cengizci Aslıhan , Güven Aylin 
Published: September 2020

Purpose
The purpose of this study is to investigate the direct impact of shopping experience of tourists on their satisfaction with shopping, while perceived crowding is used as a moderator in this relationship.

Design/methodology/approach
The proposed conceptual model was tested by an empirical study where the data were collected from 411 German tourists, visiting Kaleiçi, Antalya-Turkey.

Findings
The study results revealed that tourist shopping experience (consisting of education, esthetic, entertainment and escapism dimensions) significantly determines satisfaction with shopping. Moreover, crowding perception has a two-dimensional structure, as human and spatial crowding. Human crowding, which reflects high human density, is found to negatively moderate the effect of shopping experience on satisfaction, where spatial crowding, which is related to high space density, does not influence this relationship.

Originality/value
This study exceptionally shows that crowding perceptions of German tourists in shopping are affected by both human and spatial crowding. In addition, the moderating role of perceived crowding is clarified in the relationship between shopping experience and satisfaction.
A systematic review of the characteristics and needs of older prisoners
Authors: Wilkinson Dean , Caulfield Laura 
Published: September 2020

Purpose
The purpose of this paper is to review and understand what the existing evidence base concludes about the needs of this population. The older prisoner population is growing faster than the older general population and placing a strain on prisons. Much of the existing literature focusses on the health-care needs of, or in-prison initiatives for, older prisoners. Typically, these are responsive and lacking an evidence-based understanding of the characteristics and needs of this group.

Design/methodology/approach
This paper presents a systematic review of the existing literature on the needs and characteristics of older people in contact with the criminal justice system. After a thorough search and selection process, 21 papers, from 2002 onwards, were included in the final analysis. The review process was structured through (People, Intervention/Exposure, Comparison, Outcome) and reported using (Preferred Reporting Items for Systematic Reviews and Meta-Analyses).

Findings
The contradictions within the existing evidence base make it difficult to reach firm conclusions about the needs and characteristics of older prisoners. What is clear from the existing research are the relatively high levels of need. There is also some consensus that where older people commit homicide, the victim is likely to be an intimate partner. Overall, there is a need for consistent recording and reporting of characteristics and demographics and more systematic study design.

Originality/value
This paper has highlighted the key findings and limitations in the existing literature. Future research should make use of secondary official data sources to provide a clearer understanding of the characteristics of this group, their routes to prison, their needs and challenges they present.

Authors: Lombardi Rosa , Secundo Giustina 
Published: September 2020

PurposeThis paper aims to provide a systematic literature review (SLR) of the relationship between smart and digital technologies and organisations’ reporting processes, proposing a future research agenda. The paper examines the effects of data and digital technology on the corporate reporting process by analysing the various kinds of reports by organisations.Design/methodology/approachA two-decade assessment of studies was analysed to answer research questions. A SLR explored the role of digital and smart technologies for corporate reporting processes. The Scopus database was used as a leading source for access to the articles. Initially, 163 items were collected. After reading the abstract and several refinements, 43 prioritised publications were analysed and categorised to derive significant results.FindingsResults of the analysis highlight the following emerging research streams about the digital transformation of corporate reporting: digital technology for corporate information management and decision-making processes; digital technologies as a tool of stakeholder engagement and sustainable reporting practices; and finally, digital technologies as a way to address earning management, corporate social responsibility, accountability and transparency.Research limitations/implicationsHow digital technology and data analytics may potentially transform the corporate reporting process to make it more effective, resulting in greater transparency for shareholders and all stakeholders.Originality/valueThe originality of this paper derives from connecting, for the first time, smart and digital technologies and corporate reporting processes, drafting the state of the art of this research topic for future research.
What makes peer review helpfulness evaluation in online review communities? An empirical research based on persuasion effect
Authors: Wang Yani , Wang Jun , Yao Tang , Li Ming 
Published: September 2020

PurposeThe purpose of this paper is to examine the mechanism of how peer review helpfulness evaluation in online review communities is established, drawing upon the internalization and identification routes of persuasion effect.Design/methodology/approachBased on book reviews selected from Douban.com (a prestigious review community in China), this study used econometric models to investigate the effects of both reviews and reviewers’ characteristics on peer review helpfulness evaluation in review communities.FindingsReview internalization is more persuasive than reviewers’ identification in peer evaluations, in terms of both short and long reviews. Reviews with extreme negative ratings tend to obtain higher level of helpfulness evaluation than those with positive or moderate ratings. The influence of reviewers’ characteristics is a significant cue in helping consumers to establish the trust perception in the context of short reviews, while its function diminishes in the context of long reviews, thus suggesting the importance of reviewers’ identification for short reviews in review communities.Social implicationsThe findings will enhance current understanding of peer review review helpfulness evaluation in online review communities and help practitioners administrate community reviews intelligently, help members write better reviews and customers in their product browsing experience.Originality/valueFirst, this study enriches review evaluation research in review communities by demonstrating the importance of internalization and identification lens of persuasion effect when explaining review helpfulness; second, this study helps to confirm the existing findings that reviews with extreme negative ratings are more helpful than those with moderate or positive ratings in review communities; third, this study proposes a new perspective pertaining to the relationship between reviewers’ identification and helpfulness evaluation.

Published: September 2020

PurposeThis paper tries to generalize business process improvement (BPI) methodology. It utilizes the seven-waste framework as an essential step in the methodology. While the seven-waste concept is usually applied for manufacturing activities, this paper tries to explore the applicability of it to office-work activities. Also, this paper demonstrates that information technology can be used as a tool for reducing waste in the office-work.Design/methodology/approachA comprehensive literature review of BPI methodology studies was conducted in order to propose systematic flowcharts to represent the sequence of processes involved in each step of BPI methodology. The proposed flowcharts are applied to a case study in supply chain planning and allocation planning at a manufacturing company. The seven-waste framework is designed as part of the step, in which equivalency between the definition of waste found on the production floor and waste found in office work is presented.FindingsThe BPI methodology generally follows five steps: initialization, selection, design, implementation and evaluation. The seven-waste framework is effectively applied in the selection step. The case study shows that information technology can be used as a tool in business process improvement to reduce waste in the business process.Practical implicationsThe case study indicates that the proposed framework and methodology are proven able to reduce the three key performance indicators. They are the number of steps from 54 to 24 (55% reduction), processing time from 890 min to 313.5 min (64% reduction) and the number of the manual process from 41 to 17 (59% reduction).Originality/valueThis paper proposes a generalization of BPI methodology, the seven-waste framework in the selection step of the BPI methodology, the seven-waste concept in office-work activity and the use of information technology for BPI by reducing waste in office-work activity.

AbstractAn important toxin‐antitoxin (TA) system hok/sok, encoded by R1 plasmid of Escherichia coli, is involved in the post segregation killing of cells that have lost the plasmid. The lethal properties of hok protein have been utilized for the environmental containment of microbes and the development of potential vaccine candidates. This study aimed to demonstrate the potent anti‐microbial property of a 19 amino acid (AA) long N‐terminal fragment of hok peptide. This was accomplished by designing a conditional suicide system based on hok gene expression cloned in an anhydrotetracycline (aTc) inducible vector – pASK75. Heat shock and electroporation were utilized for the transformation of Escherichia coli and Vibrio cholerae cells, respectively. The minimal induction concentration (MIdC) of aTc, determined by analyzing the expression of green fluorescent protein cloned separately into pASK75 vector, was 30 ng/mL. As hok gene was synthesized de novo (using recombinant polymerase chain reaction) in our study, various random sized hok fragments were generated (as a result of the error‐prone nature of Taq polymerase). The smallest hok fragment able to bring about effective antimicrobial killing was a 19 AA long N‐terminal fragment of hok having the wild type sequence, except for the carboxy terminus AA residue. The MIdC of aTc in our experiments was 6‐fold lower than previously reported, making our bacterial clones suitable for use in mammalian systems as potential vaccine candidates. Based on our experiments, we hypothesize the 19 AA long N‐terminal fragment of hok peptide to be the smallest possible hok fragment sufficient to bring about effective antimicrobial killing.
Men, masculinities and diabetes: ‘doing gender’ in Italian men’s narratives of chronic illness
Authors: Quaglia Valeria 
Published: September 2020

AbstractThere has been a growing interest in the study of masculinity and its intersection with health. However, and despite epidemiological data showing men’s general disadvantage in health, there are only a few empirical studies that explore men’s experiences of chronic illness. Drawing on empirical data collected in qualitative research on masculinity and autoimmune diabetes, this article investigates the multiple ways in which gender may intersect with health, in an attempt to go beyond the widespread thesis that ‘masculinity is bad for men’s health’. In line with more recent critical perspectives on the study of men’s health that have challenged this oversimplistic assumption, this work further problematises masculinity in relation to health and illness. In‐depth interviews have been conducted with 40 young/adult diabetic men from working/middle‐class backgrounds. The findings show that gender might intersect health in complex ways and diabetic men can embody and re‐signify health practices in order to fulfil or redefine dominant ideals of masculinity. From the analysis, three different ‘diabetic masculinities’ have been identified and will be discussed: the Diabetic Quantified Self, the Athlete and the Free Spirit.

ObjectivesTo develop and internally validate risk prediction models identifying women at risk for cardiovascular severe maternal morbidity (CSMM).DesignA retrospective cohort study.SettingAn obstetric teaching hospital between 2007 and 2017.PopulationA total of 89 681 delivery hospitalisations.MethodsWe created and evaluated two models, one predicting CSMM at delivery (delivery model) and the other predicting CSMM postpartum following discharge from delivery hospitalisation (postpartum CSMM). We assessed model discrimination and calibration and used bootstrapping for internal validation.Main outcome measuresCardiovascular severe maternal morbidity comprised the following confirmed conditions: pulmonary oedema/acute heart failure, myocardial infarction, aneurysm, cardiac arrest/ventricular fibrillation, heart failure/arrest during surgery or procedure, cerebrovascular disorders, cardiogenic shock, conversion of cardiac rhythm and difficult‐to‐control severe hypertension.ResultsThe delivery model contained 11 variables and 3 interaction terms. The strongest predictors were gestational hypertension, chronic hypertension, multiple gestation, cardiac lesions or valvular heart disease, maternal age ≥40 years and history of poor pregnancy outcome. The postpartum model comprised eight variables. The strongest predictors were severe pre‐eclampsia, non‐Hispanic Black race/ethnicity, chronic hypertension, gestational hypertension, non‐severe pre‐eclampsia and maternal age ≥40 years at delivery. The delivery and postpartum models had an area under the receiver operating characteristic curve of 0.87 (95% CI 0.85–0.89) and 0.85 (95% CI 0.80–0.90), respectively. Both models were adequately calibrated and performed well on internal validation.ConclusionsThese tools may help providers to identify women at highest risk of CSMM and enable future prevention measures.Tweetable abstractRisk assessment tools for cardiovascular severe maternal morbidity were developed and internally validated.
