Extremely low sample size allows age and growth estimation in a rare and threatened shark
Authors: Kyne Peter M. , Smart Jonathan J. , Johnson Grant 
Published: September 2022

AbstractUnderstanding life history parameters is key to assessing biological productivity, extinction risk, and informing the management of exploited fish populations. Age-and-growth analyses in chondrichthyan fishes (sharks, rays, and ghost sharks) is primarily undertaken through counting band pairs laid down in vertebrae. For rare, threatened, and protected species such as river sharks (family Carcharhinidae; genus Glyphis) of northern Australia, obtaining sufficient samples of vertebrae may not be possible. Here we use a very sample size, selective size-class sampling, and back-calculation techniques to provide age and growth data on the Speartooth Shark Glyphis glyphis from which comprehensive sampling is not possible. Ten individuals were sampled from the Adelaide River, Northern Territory, Australia. Length-at-age models were applied to the observed and back-calculated data with the sexes combined due to the small sample size and growth estimated using a multi-model framework. Band pair counts produced age estimates of 0–11 years. Most model parameter estimates for length-at-birth (L0) and asymptotic length (L∞) were biologically plausible. The model averaged parameters for the observed data were total length (TL) and TL, and for back-calculated data were TL and TL. Overall, the parameter standard errors and model residual standard errors were lower for the back-calculated data due to the addition of interpolated data. Analysed samples were restricted to juveniles and sub-adults as adult G. glyphis have not been encountered in the Northern Territory. The ageing results suggest an age-at-maturity of >12 years for this species. The lack of mature individuals in the sample means that this analysis should be considered as a partial growth curve with length-at-age estimates that are valid over the available age range. The results presented here provide the first age and growth estimation for river sharks.

Published: September 2022

AbstractChemokine receptors are GPCRs that regulate chemotactic migration of a wide variety of cells including immune and cancer cells. Most chemokine receptors contain features associated with the ability to stimulate G protein signaling during β-arrestin-mediated receptor internalization into endosomes. As endosomal signaling of certain non-GPCR receptors plays a major role in cell migration, we chose to investigate the potential role of endosomal chemokine receptor signaling on mechanisms governing this function. Applying a combination of pharmacological and cell biological approaches, we demonstrate that the model chemokine receptor CCR7 recruits G protein and β-arrestin simultaneously upon chemokine stimulation, which enables internalized receptors to activate G protein from endosomes. Furthermore, spatiotemporal-resolved APEX2 proteome profiling shows that endosomal CCR7 uniquely enriches specific Rho GTPase regulators as compared to plasma membrane CCR7, which is directly associated with enhanced activity of the Rho GTPase Rac1 and chemotaxis of immune T cells. As Rac1 drives the formation of membrane protrusions during chemotaxis, our findings suggest an important integrated function of endosomal chemokine receptor signaling in cell migration.

Published: September 2022

ABSTRACTWhile green turtles (Chelonia mydas) were once abundant throughout the Caribbean, overexploitation has dramatically reduced their numbers. We conducted a 168-day simulated grazing experiment to determine how loss of this once-abundant mega-herbivore could have affected the productivity and community composition of Thalassia testudinum-dominated seagrass beds in Bocas del Toro, Panama. Simulated grazing reduced both percent cover and productivity of T. testudinum. High runoff and local pollution from industrial farming may limit light availability and reduce seagrass photosynthetic performance to replace biomass lost to simulated grazing. Other seagrass species and algae failed to colonize space opened by reductions in T. testudinum percent cover. Many plots subjected to simulated grazing were also bioturbated by stingrays. Relevance of these findings to balancing sea turtle and seagrass conservation efforts are discussed.

Survival of Russian banks: how efficient are the control measures?
Authors: Barajas Angel , Krakovich Victor , López-Iturriaga Félix J. 
Published: September 2022

PurposeIn this paper, the authors study the failure of Russian banks between 2012 and 2019.Design/methodology/approachThe authors analyze the entire population of Russian banks and combine a logit model with the survival analysis.FindingsIn addition to the usual determinants, the authors find that not-failed banks have higher levels of fulfillment of the Central Bank requirements of solvency, liquidity, provide fewer loans to their shareholders and own more shares of other banks. The results of this study suggest an asymmetric effect of the strategic orientation of banks: whereas the proportion of deposits from firms is negatively related to the probability of failure, the loans to firms are positively related to bankruptcies. According to this research, the fact of being controlled by a foreign bank has a significant negative relationship with the likelihood of failure and moderates the effect of bank size, performance and growth on the bankruptcy likelihood.Practical implicationsOn the whole, the results of this study support the new Central Bank rules, but show that the thresholds imposed by the Russian regulator actually do not make a difference between failed and not failed banks in the short and medium term.Originality/valueThe authors specially focus on the effectiveness of new rules issued by the Central Bank of Russia in 2013.

Authors: Chen Kaung-Hwa , Huang Leo , Ye Ying 
Published: September 2022

Purpose
This study aims to construct a scale for measuring the spa hotel experiencescape in wellness tourism, clarify the mechanism through which wellness tourism experiencescape influences revisit intention and investigate the mediation roles of authenticity, memorability and organizational identification.

Design/methodology/approach
This study conducted content analysis of interviews, online reviews and relevant articles and used the concept of experiencescape to interpret spa hotels’ experiential environment. The stimulus–organism–response (SOR) model was used as the basis for introducing authenticity, memorability, organizational identification and revisit intention to investigate how wellness tourism experiencescape affects tourists’ behavior. In total, 488 valid questionnaires were collected at Taiwanese spa hotel clusters.

Findings
Four factors of spa hotel experiencescape were identified: health promotion treats, mental learning, unique travel experience and healthy diet. Existential authenticity–memorability and existential authenticity–organizational identification exerted full positive mediation effects in the relationship between wellness tourism experiencescape and revisit intention.

Practical implications
This study provides guidance on experience design for spa hotels. It promotes the consideration of existential authenticity in wellness tourism design.

Originality/value
The COVID-19 pandemic has raised awareness of wellness, drastically increasing the potential of the wellness tourism market. This study investigated the construction of wellness tourism experiencescape and its influence, and the findings can facilitate post-pandemic restoration of the wellness tourism industry. On the basis of SOR model, a chain mediation model was proposed to reveal the influence of wellness tourism experiencescape on revisit intention. Existential authenticity was discovered to play a crucial role in the relationship between wellness tourism experiencescape and revisit intention, which suggests that existential authenticity should be considered during service design and in marketing strategies for wellness tourism.

Is it better to communicate product information abstractly or concretely? The role of consumer product expertise and shopping-stage mindset
Authors: Trzebinski Wojciech , Gaczek Piotr , Marciniak Beata 
Published: September 2022

Purpose
This paper aims to investigate the effect of product-related description abstractness/concreteness on perceived trustworthiness and the role of consumer product expertise and shopping-stage mindset in the persuasiveness of abstract vs concrete product descriptions.

Design/methodology/approach
Two online experiments were conducted: Study 1 (description abstractness – manipulated between-subject; consumer product expertise, perceived trustworthiness, purchase intent – measured), Study 2 (consumer shopping-stage mindset – manipulated between-subject; description abstractness – manipulated within-subject; consumer product expertise, perceived trustworthiness, abstract/concrete description preference – measured).

Findings
The negative effect of the abstractness (abstract descriptions vs the ones supplemented with relevant product details) on description trustworthiness was evidenced in Study 1. Trustworthiness was positively related to purchase intent, especially for high product expertise. Study 2 replicated the effect of product description abstractness on its trustworthiness in terms of two other forms of abstractness (abstract descriptions vs the ones supplemented with irrelevant product details and product benefits vs attributes). The goal-oriented (vs comparative) mindset had a positive effect on the benefit (vs attribute) description preference, especially for high product expertise.

Practical implications
For marketers, the results suggest the positive consequences of presenting concrete information on product attributes and the conditions enhancing the effectiveness of presenting product benefits.

Originality/value
The paper integrates the existing views on consumer response to abstract vs concrete information (lexical abstractness/concreteness, means-end chain theory) and links them to consumer product expertise and shopping-stage mindset.
Adopting to the virtual workplace: identifying leadership affordances in virtual schools
Authors: Willermark Sara , Islind Anna Sigridur 
Published: September 2022

Purpose
This study aims to explore virtual leadership work within educational settings in the light of social disruption. In 2020, a global pandemic changed the way we work. For school leaders, that involved running a virtual school overnight. Although there is a stream of research that explores leadership in solely virtual communities, there is a gap in the literature regarding practices that transition from analog to virtual practices and the changes in leadership in those types of work practices.

Design/methodology/approach
The data gathering method constitutes a questionnaire to explore school leaders’ experiences of virtual work and virtual leadership in light of social disruption. One hundred and five Swedish school leaders answered the questionnaire covering both fixed and open questions.

Findings
The results show that school leaders’ general experiences of transition to virtual school have worked relatively well. We show how the work changes and shift the focus in the virtual workplace.

Originality/value
The author’s contributions include theorizing about leadership affordances in virtual schools and providing implications for practice. The authors summarize our main contribution in five affordances that characterize virtual leadership, including a focus on core activities, trust-based government, 1:1 communication with staff, structure and clarity and active outreach activities. The results could be interesting for understanding the radical digitalization of leadership in the digital workplace.
The equity of opportunities in emerging service work robotisation
Authors: Turja Tuuli 
Published: September 2022

Purpose
In a best-case scenario, both organisations and their employees gain from technological changes by staying up to date on developing digitalisation. However, opportunities to learn and use modern technologies may not be shared equally in the workplace. Employee groups can be divided between those with and without access to new technologies. This study aims to examine the extent to which the position of an employee may be associated with the opportunity to work with robots.

Design/methodology/approach
Health-care work was chosen as an exemplary context of emerging robotisation. To gain correlative evidence on how the position and technology orientation of an employee associate with access to care robots, the study used online survey data collected from Finnish care workers (N = 226).

Findings
Workplace hierarchies were found to play a significant part in robotisation. Management experience increased the probability for an employee to have access to care robots, but this position did not differentiate between the employees in their aspiration to use care robots. Individual interest in technology was associated with robot use only among care workers with no management experience, whereas managers’ access to robots did not depend on their personal interests.

Originality/value
This study brings new information about the equity of robot-use opportunities in workplaces. Distinctive to care robots was the significant number of motivated non-users. Thus, adding to the categories of “have-bots”, “have-nots” and “want-nots”, this study introduces an important group of “want-bots”.

Authors: Mohammadi Mohammad Reza , Mostafavi Seyed-Ali , Khalkhali Aref 
Published: September 2022

PurposeNutrition Bio Shield (NBS) supplement is a natural product that is processed from whole wheat grains. This study aims to determine its effects on depression, anxiety, stress and food craving in women with depression and obesity in a double-blind randomized clinical trial.Design/methodology/approachFifty-six eligible clients with body mass index ≥ 25 and mild or moderate depression signed the informed consent form. They were randomly assigned to receive daily 5 g of NBS or placebo. The assessments included the depression, anxiety and stress-21 questionnaire, food craving questionnaire, visual analogue scale for appetite, precise anthropometric measurements and body composition analyses. The assessments were conducted at the baseline and repeated after four and eight weeks. One month after the study completion, the participants’ weight was assessed. The authors analyzed the data by independent samplet-test, repeated measures analysis of variance and multivariate analyses of covariance (MANCOVA).FindingsAt the baseline, no significant differences were observed between the groups regarding the main and demographic variables. After four weeks, stress reduced significantly in the NBS group (p= 0.04), and after eight weeks, anxiety (p= 0.02), stress (p= 0.008) and food craving (p= 0.05) reduced significantly in the NBS group compared with the placebo. After controlling for the demographic variables and baseline measurements, MANCOVA model revealed a significant effect of NBS in reducing anxiety (Eta-squared = 0.28;p= 0.001) and stress (Eta-squared = 0.19;p= 0.009). Fisher’s exact test showed no significant difference regarding side effects between NBS and placebo (p= 0.47).Originality/valueNBS supplement is a patent and natural product that is processed from whole wheat grains. This product was efficient in reducing stress and anxiety after controlling for demographic variables and baseline measurements compared with the placebo and was safe.
Police legitimacy regimes and the suppression of citizen oversight in response to police violence
Authors: Rocha Beardall Theresa 
Published: September 2022

AbstractA lack of formal accountability in the aftermath of police violence against communities of color has long fueled public demands for increased police oversight. Yet, little is known about how interorganizational relationships affect citizen complaint investigations once citizen review boards (CRBs) are established. Drawing on ethnographic fieldwork, interviews, and archival sources about the Syracuse Citizen Review Board in New York State, I show how CRBs operate as bureaucratic agencies that ostensibly address police misconduct, yet are managed by municipal power relations that neutralize the agency's ability to actualize change. Specifically, I find that a CRB's embeddedness within a municipality's interorganizational field creates a site of contestation to ensure public legitimation of police despite community concern. To show how the aims of citizen oversight can be upended within the structural and practical politics of local government, I introduce the concept of a police legitimacy regime: a set of (in)formal policies, organizations, and actors that protect and promote the legitimacy of state police power. In Syracuse, police protection happens at the expense of residents’ demands for police reform, and I conclude by outlining the implications of this research for other communities seeking citizen‐led approaches to police accountability.
Associations between potential causal factors and colorectal cancer risk: A systematic review and meta‐analysis of Mendelian randomization studies
Authors: Deng Yunyang , Wang Lyu , Huang Junjie , Ding Hanyue , Wong Martin Chi Sang 
Published: September 2022

ObjectiveTo summarize the associations between potential causal factors and colorectal cancer (CRC) risk based on existing Mendelian randomization studies.MethodsThis systematic review and meta‐analysis involved a literature search in Embase and Medline. All published articles using Mendelian randomization to explore potential causal factors of CRC were included. Studies that reported Mendelian randomization estimates of standard deviation changes in exposures were included in the meta‐analysis. Subgroup analyses based on sex and anatomical sites were performed.ResultsOne hundred and ninety studies presented in 51 articles were included in systematic review, and 114 studies conducted in 32 articles were included in the meta‐analysis. Adult body mass index, waist circumference, waist hip ratio, body height, body fat percentage, arm fat ratio, childhood obesity, lifetime cigarette consumption, short sleep, coffee consumption, and blood levels of vitamin B12, arachidonic acid, stearic acid, and insulin‐like growth factor binding protein 3 were positively associated with CRC risk. Conversely, acceleration–vector–magnitude physical activity, milk consumption, and blood levels of adiponectin, linoleic acid, α‐linolenic acid, oleic acid, palmitoleic acid, interleukin‐6 receptor subunit‐α, and tumor necrosis factor were inversely associated with CRC risk.ConclusionsMost obesity‐related anthropometric characteristics, several unhealthy lifestyles, and blood levels of some micronutrients, fatty acids, and diabetes‐related biomarkers were positively associated with CRC risk. In contrast, some lifestyles and blood levels of some fatty acids and inflammatory biomarkers were inversely associated with CRC risk. Future studies with more valid genetic variants are needed for factors with discrepancies between Mendelian randomization and epidemiological studies.
