Dating ancient humans splits by estimating Poisson rates from mitochondrial DNA parity samples
Authors: Hallak Keren Levinstein , Rosset Saharon 
Published: April 2023

AbstractWe tackle the problem of estimating species divergence times, given a genome sequence from each species and a large known phylogenetic tree with a known structure (typically from one of the species). The number of transitions at each site from the first sequence to the other is assumed to be Poisson distributed, and only the parity of the number of transitions is observed. The detailed phylogenetic tree contains information about the transition rates in each site. We use this formulation to develop and analyze multiple estimators of the divergence between the species. To test our methods, we use mtDNA substitution statistics from the well-established Phylotree as a baseline for data simulation such that the substitution rate per site mimics the real-world observed rates. We evaluate our methods using simulated data and compare them to the Bayesian optimizing software BEAST2, showing that our proposed estimators are accurate for a wide range of divergence times and significantly outperform BEAST2. We then apply the proposed estimators on Neanderthal, Denisovan, and Chimpanzee mtDNA genomes to better estimate their TMRCA (Time to Most Recent Common Ancestor) with modern humans and find that their TMRCA is sub-stantially later, compared to values cited recently in the literature.
Luteinizing hormone stimulates ingression of mural granulosa cells within the mouse preovulatory follicle
Authors: Owen Corie M. , Jaffe Laurinda A. 
Published: April 2023

AbstractLuteinizing hormone (LH) induces ovulation by acting on its receptors in the mural granulosa cells that surround a mammalian oocyte in an ovarian follicle. However, much remains unknown about how activation of the LH receptor modifies the structure of the follicle such that the oocyte is released and the follicle remnants are transformed into the corpus luteum. The present study shows that the preovulatory surge of LH stimulates LH receptor-expressing granulosa cells, initially located almost entirely in the outer layers of the mural granulosa, to rapidly extend inwards, intercalating between other cells. The cellular ingression begins within 30 minutes of the peak of the LH surge, and the proportion of LH receptor-expressing cell bodies in the inner half of the mural granulosa layer increases until the time of ovulation, which occurs at about 10 hours after the LH peak. During this time, many of the initially flask-shaped cells appear to detach from the basal lamina, acquiring a rounder shape with multiple filipodia. Starting at about 4 hours after the LH peak, the mural granulosa layer at the apical surface of the follicle where ovulation will occur begins to thin, and the basolateral surface develops invaginations and constrictions. Our findings raise the question of whether LH stimulation of granulosa cell ingression may contribute to these changes in the follicular structure that enable ovulation.Summary sentenceLH-induced ingression of LH receptor-expressing cells within the mural granulosa layer of the ovarian follicle is a new component in the complex sequence of structural changes that lead to ovulation.
Perceived work identity deprivation: the construct, measurement, and validity
Authors: Huang Jie , Tang Chunyong , Li Yali 
Published: April 2023

PurposeThis research aims to present the results of a study that operationalizes the construct of perceived work identity deprivation (PWID) and examines its validity.Design/methodology/approachThe authors adopted a mixed method design in this study where a Likert-type scale to measure PWID was developed based on the interviews of 40 workers and the questionnaires of 625 participants successively. Later, the generalizability of the scale was tested through quantitative data from 412 workers. Finally, validity analysis was conducted based on 380 usable questionnaires. Data were analyzed using IBM SPSS 24 and Mplus 7.0.FindingsThe findings of the study indicate that the reliability measures, exploratory factor analyses, confirmatory factor analysis and subsequent convergent and discriminant validity tests support the PWID scale. The nomological validity of PWID is also presented, which demonstrates its predictive validity.Originality/valueDespite highlighting the importance of work identity, prior research lacked to provide empirical foundations to understand this perception. This study fills this gap in the literature by providing a measure of PWID, distinguishing it from similar constructs and establishing convergent, discriminant and nomological validity. Moreover, by extending the range of theoretical and measurable deprivation of work identity, the authors hope to allow research to take into account a more complete picture of it. PWID scale can be used to develop more relevant suppression plans.
Barriers to innovation in construction organizations of different sizes: a case study in Vietnam
Authors: Nguyen Minh Van 
Published: April 2023

PurposeThis study aims to determine barriers to innovation and to develop a quantitative model for the barrier to innovation in Vietnamese construction organizations of different sizes.Design/methodology/approachA literature review and discussions with experienced practitioners were implemented to determine barriers to innovation in construction organizations. The rank-based non-parametric test analyzed collected data from a questionnaire survey to examine if there were significant differences between the three groups of organizations, including small, medium and large construction organizations. The fuzzy synthetic evaluation (FSE) technique was employed to develop barrier indexes (BIs) for organizations of different sizes in Vietnam.FindingsThe findings showed 17 barriers to innovation which were categorized into four groups, including organizational, human resources, economic and market barriers. Statistical analysis revealed significant differences regarding barriers to innovation between small, medium and large construction organizations in Vietnam. The post hoc test highlighted barriers to innovation differently separated into two groups: SMEs and large construction organizations. The FSE analysis integrated the identified barriers into the comprehensive BIs for SMEs and large construction organizations. The FSE analysis illustrated that the organizational barrier is the most critical barrier for SMEs. On the other hand, the market barrier received the most significant attention in large construction organizations.Originality/valueThis research is one of the first integrated barriers to innovation into a comprehensive formulation. The indexes provide the decision-makers with a practical and reliable tool to evaluate barriers to innovation in construction organizations of different sizes.
The influence of religious beliefs on the expectations of individual social class mobility
Authors: Chen Xiaodong , Bhuiyan Miraj Ahmed 
Published: April 2023

PurposeThis paper examines the in-depth relationship between religious beliefs and individual social class mobility expectations in China.Design/methodology/approachThe data used in this article are mainly from the China Comprehensive Social Survey in 2010 (CGSS2010). Compared with other years' CGSS data, CGSS2010 includes a module on religious topics, and the questionnaire information related to religion is more comprehensive and suitable for in-depth analysis.FindingsThe results show that religious beliefs have a significant positive impact on personal social class mobility expectations. Based on the principle of diminishing marginal returns on capital, the positive impact of religious belief on the expectation of individual social class mobility is more significant in groups with nonagricultural household registration, higher education level, older age and better family background conditions. However, with the further improvement of family background conditions, this positive impact begins to weaken. In addition, possible channels of action include prejudice effects, psychological effects, individual capital effects and social capital effects. The results of other effects are positive except for the prejudice effect. Overall, religious beliefs, as one of the important components of contemporary Chinese culture, have a positive significance for the “Chinese Dream”.Originality/valueThere is also little literature globally that provides an in-depth analysis of the relationship between religion and economic development. Studies have led to an understanding of the relationship between religious beliefs and individual social class mobility expectations. But it is unclear whether theories developed based on Western spiritual experience will be applicable to China or not. The authors have tested for China.
Inferring quality from price: the effect of stereotype threat on price–quality judgments
Authors: Song Lei , Suri Rajneesh , Huang Yanliu 
Published: April 2023

Purpose
This paper aims to examine how a stereotype threat, which entails being aware of a negative stereotype about one’s social group (e.g. gender), affects consumers’ price perceptions.

Design/methodology/approach
The authors conducted four studies to examine the effect of a stereotype threat on consumers’ perceptions of a product’s price–quality relationship.

Findings
This study found that being aware of a negative stereotype about one’s social group (i.e. gender here) led consumers to use price more as a quality indicator. This study also determined that reappraisal – an alternative way of coping with stereotype threats – reduced the impact of a stereotype threat and, subsequently, decreased reliance on price to infer quality.

Research limitations/implications
This research contributes to the consumer decision-making literature by examining stereotype threat effect in in-store product purchasing contexts; provides theoretical contributions to the processing of price information by exploring the role of a stereotype threat in price perceptions and revealing that impairment of consumers’ working memory resources affects price perceptions; adds to the existing stereotype threat literature by investigating the effect of a stereotype threat on systematic versus heuristic information processing; and advances the stress and coping literature by suggesting that consumers adopting a reappraisal strategy cope better with a stereotype threat than when opting for a suppression strategy.

Practical implications
This research provides important implications for consumers. For example, the findings suggest that consumers who would like to avoid paying more for stereotype-associated products may adopt reappraisal to cope with a stereotype threat. Reappraisal may allow consumers to use fewer cognitive resources when coping with stereotype threats, thus minimizing the possibility that they might overpay for high-priced products.

Originality/value
This research uniquely examines the effect of a stereotype threat on consumers’ price perceptions and the role of reappraisal in this effect.
What does corporate sustainability reporting imply to auditors? Evidence from going-concern opinions and discretionary accruals
Authors: Tuo Ling , Han Shipeng , Rezaee Zabihollah , Yu Ji 
Published: April 2023

PurposeThis study aims to address the unanswered question of whether corporate sustainability has an impact on auditors’ overall judgment and to provide incremental evidence that corporate sustainability reporting has significant effect on financial auditors’ judgment.Design/methodology/approachFollowing prior research, the authors, respectively, apply auditors’ decisions on going-concern opinions and three discretionary accrual measures as proxies for auditor conservatism over financial risk and financial reporting risk. The authors collect corporate sustainability reporting and sustainability assurance data of U.S. firms from the global reporting initiative (GRI) database to construct and measure firms’ sustainability reporting activities.FindingsThe authors find that nonreporting firms are more likely to receive going-concern opinions than the reporting firms. In addition, reporting firms have a larger scale of discretionary accruals than their nonreporting counterparts. The authors also obtain consistent findings that sustainability assurance or accounting assurance providers strengthen the effect of sustainability reporting on auditors’ judgment.Research limitations/implicationsFirst, using discretionary accruals as measures of auditor conservatism is controversial, as accruals are the joint product by auditors and clients. Second, binary variables as a measure of sustainability reporting activities limit the inference. Lastly, the findings based on limited samples may weaken the external validity.Practical implicationsThe findings imply that firms engaging in sustainability activities are lower in financial or financial reporting risk. Firms can influence audit practitioners’ overall judgment through sustainability reports. Sustainability commitments and reporting have become a part of firms’ risk management.Social implicationsThe findings imply that sustainability reporting could become an integrated part of regulated corporate disclosure. Sustainability assurance reduces social costs by lending credibility to sustainability reports.Originality/valueThis paper provides incremental evidence that sustainability reports provide useful information and signals that influence auditors’ professional judgment. The findings also suggest that sustainability assurance strengthens auditors’ confidence in using sustainability information, thus amplifying the effect of sustainability reporting on auditors’ judgment.
‘Space-as-a-service’: A premium to office rents?
Authors: Tsolacos Sotiris , Lee Stephen , Tse Hoi 
Published: April 2023

PurposeThis study aims to examine the impact of “space-as-a-service” (SAAS) provision on office rents in the UK and quantify premia to office rents.Design/methodology/approachUsing hedonic modelling techniques the authors are able to quantify the impact of a number of SAAS features on office rents in the City of London using CoStar data. The authors control for the quality of the buildings by focussing on five-star buildings, rated by CoStar, as these buildings are more likely to incorporate SAAS features.FindingsUsing data on 317 transactions in 37 City of London Office buildings over the period 1 November 2004–15 July 2020, the authors find that tenant exclusive mobile applications (MAPPS) and a public terrace or rooftop command a rent premium of around £13 and £6.5 per sq. ft per annum, respectively. However, other SAAS features such as conferencing facilities, on-site fitness centre and touch down space have no significant impact on office rents. The impact of exclusive MAPPS varies with size of net lettable area.Research limitations/implicationsThe SAAS real estate model is an emerging trend in the office market. As it grows in importance more research questions will have to be investigated. The present study raises awareness of the need to specify SAAS features and form a rating system that will facilitate future research on the subject.Practical implicationsThe conclusion from the present investigation is that only two SAAS features have a positive impact on office (tenant exclusive mobile apps and a public terrace or rooftop), which suggest that these two features may form the basis of any future SAAS rating system. These two SAAS components should carry more weight in valuations and pricing.Originality/valueTo the best of the authors’ knowledge, this is the first study that attempts to quantify the impact of SAAS features on office rents.
The influence of host country education and professional experience on repatriation intentions: an examination of French long-term self-initiated expatriates in the United States
Authors: Ryan Jason 
Published: April 2023

PurposeThe aim of this study is to develop a better understanding of how the transferability and recognition of host country professional experience and educational credentials impact the repatriation intentions of long-term self-initiated expatriates (SIEs). To that end, the study interviews a sample of American-educated French long-term SIEs in the United States (US) to assess how both their higher education and professional experience influence their social identity in their home country, France and their perceived repatriation opportunities.Design/methodology/approachThis study applies social identity theory to the examination of the combined impact of higher education and work experience abroad on the repatriation expectations of long-term SIEs. The author interviewed twenty-one French SIEs who attended universities in the US and remained there afterward to begin their careers.FindingsThe findings of this study confirm that the repatriation intentions of long-term SIEs are strongly influenced by concerns about the ability to maintain their host country standard of living in their home country. It also finds that foreign educational credentials and professional experience can constrain the ability of long-term SIEs to repatriate easily and gain acceptance. To overcome this, long-term SIEs often feel that they must embrace alternative repatriation strategies to maintain the lifestyle that they enjoyed while abroad when returning back home.Originality/valueThis study examines a sample of long-term SIEs from one home country, France, who left to attend university in the same host country, the US. It assesses how the experiences of those who remained in the US afterward to start their careers impacted their repatriation intentions. This study contributes to the body of knowledge on the context of self-initiated expatriation by examining the influence of host-country educational credentials and work experience on the repatriation intentions of long-term SIEs.
#MeToo, Covid-19 and the new workplace: re-examining institutional discrimination's impact on workplace harassment of expatriates following two exogenous shocks
Authors: Obenauer William , Rezaei Shafagh 
Published: April 2023

PurposeReplication is essential to science for the purpose of (1) updating previously accepted knowledge and (2) testing the boundary conditions of this knowledge. Although Bader et al.’s (2018) impactful paper on gender harassment experienced by expatriates was only published five years ago, there have been two relevant exogenous shocks to the environment since they collected their data, making this study an excellent target for replication.Design/methodology/approachThree-hundred ninety-one expatriates who were currently working in 79 different countries completed an electronic survey that included scales for gender harassment, ethnicity harassment, general stress, frustration and job satisfaction. Data were analyzed using partial least-squares structural equation modeling (PLS-SEM) in Stata17.FindingsConsistent with prior research, gender had a significant relationship with workplace gender harassment (ß = 0.228, p < 0.001) such that males experienced lower levels of harassment than other expatriates. The relationship between race/ethnicity and experiences of ethnicity harassment was dependent upon model specification. Workplace harassment had a negative relationship with job satisfaction (gender harassment, ß = −0.114, p = 0.030; ethnicity harassment; ß = −0.146, p = 0.002) and a positive relationship with frustration (gender harassment, ß = 0.231, p < 0.001; ethnicity harassment, ß = 0.213, p < 0.001).Originality/valueUsing a larger, more diverse sample than that used in prior research, the authors were able to test the generalizability of accepted knowledge. While the authors replicated many findings identified in prior research, they failed to replicate the effects pertaining to the relationship between macro-level variables and experiences of harassment. Given that macro-level variables play a key role in status construction theory (SCT), this research raises important questions for future work.
Usefulness of immunofluorescence overlay antigen mapping in the identification of autoantigen in anti‐p200 pemphigoid
Authors: Kitayama Shohei , Makino Teruhiko , Hayashi Masao , Mizawa Megumi , Ishii Norito , Hashimoto Takashi , Shimizu Tadamichi 
Published: April 2023

AbstractAnti‐p200 pemphigoid is a rare subepidermal blistering disease showing immunoglobulin G (IgG) autoantibodies reactive with a 200‐kDa protein. In most patients, serum IgG antibodies react with laminin γ1. The diagnosis of anti‐p200 pemphigoid is occasionally difficult, mainly due to the lack of standardized tests. We performed fluorescence overlay antigen mapping by laser scanning confocal microscopy (FOAM‐LSCM) to identify autoantigens in an anti‐p200 pemphigoid patient and assessed its usefulness for the diagnosis. A 71‐year‐old man presented with blisters and erosions on the bilateral forearms. No mucosal lesions were observed. Laboratory examinations revealed mild leukocytosis and antinuclear antibody negativity. A histopathological examination showed subepidermal blisters with neutrophil infiltration. Direct immunofluorescence showed linear IgG staining along the basement membrane zone. Indirect immunofluorescence using 1 M NaCl‐split skin sections revealed IgG reactivity on the dermal side. Immunoblotting detected circulating IgG autoantibodies that reacted with a 200‐kDa protein. Accordingly, anti‐p200 pemphigoid was diagnosed. FOAM‐LSCM revealed that the patient's IgG signals were co‐localized with laminin γ1 but were observed above type VII collagens. A direct immunofluorescent analysis for IgG deposition patterns showed an n‐serrated pattern. Thus, FOAM‐LSCM may be useful for diagnosing anti‐p200 pemphigoid.
The Politics of Race and the Future of British Political History
Authors: Liburd Liam 
Published: April 2023

AbstractThis article addresses the field of British political history's blind spot when it comes to race. Where modern British political historians are comfortable approaching politics in ‘high’ and ‘popular’ forms as well as in terms of ideas, institutions and policy, they often struggle even to see a politics of race in operation. Using examples drawn from research on the post‐1945 history of the white supremacist movement in Britain, this article maintains that the means to render race visible in the political history of modern Britain lies in the incorporation of previously overlooked perspectives. In search of these perspectives, it looks to black British history and critical studies of race. In particular, it highlights analyses and critiques of British racism by black political activists, from those who organised in response to the 1959 murder of Kelso Cochrane, to the Black Power groups of the 1970s.
