Factors Affecting Catchability in Longline Fishing of Red Grouper in the Southeastern Gulf of Mexico
Authors: Rincón‐Sandoval Luis A. , Velázquez‐Abunader Iván , Brulé Thierry 
Published: July 2019

AbstractCatchability (q) is a key parameter in stock assessment that can vary in response to biological (e.g., abundance), spatial (e.g., fishing zones), and fishing technique and tactic (e.g., fishing gear design) factors. Few studies have been done on the influence of these sources of variation on q estimates. Catchability was calculated for Red Grouper Epinephelus morio caught with bottom longlines in two coastal zones fished by the small‐scale fleet in Yucatan, Mexico. Experimental data collected from these catches were used to assess the effect on q‐values of fishing zone and depth stratum, hook and bait size, and fish length. Three longlines were each equipped with one of three sizes (13/0, 14/0, or 15/0) of Mustad circle hooks. Bait was Atlantic Thread Herring Opisthonema oglinum in one of two sizes: 4 or 8 cm long. Sampling occurred in two zones (west and east coast) and in three depth strata (10–15 m, 15–20 m, and >20 m). Generalized linear models were used to identify any effect of the analyzed variables on q. Fishing depth and bait size alone had no apparent effect on q, but a combined effect of hook (14/0) size and bait (8 cm) size on q was observed. Fishing zone, hook size, and fish total length were significant sources of variation. The observed catchability patterns suggest possible high fishing mortality in juvenile Red Grouper related to fishing zone, hook and bait size, and fish length, highlighting the need to consider these variables to improve stock assessments of the Campeche Bank Red Grouper fishery.

AbstractCatalytic benzene C−H activation toward selective phenol synthesis with O2 remains a stimulating challenge to be tackled. Phenol is currently produced industrially by the three‐steps cumene process in liquid phase, which is energy‐intensive and not environmentally friendly. Hence, there is a strong demand for an alternative gas‐phase single‐path reaction process. This account documents the pivotal confined single metal ion site platform with a sufficiently large coordination sphere in β zeolite pores, which promotes the unprecedented catalysis for the selective benzene hydroxylation with O2 under coexisting NH3 by the new inter‐ligand concerted mechanism. Among alkali and alkaline‐earth metal ions and transition and precious metal ions, single Cs+ and Rb+ sites with ion diameters >0.300 nm in the β pores exhibited good performances for the direct phenol synthesis in a gas‐phase single‐path reaction process. The single Cs+ and Rb+ sites that possess neither significant Lewis acidic−basic property nor redox property, cannot activate benzene, O2, and NH3, respectively, whereas when they coadsorbed together, the reaction of the inter‐coadsorbates on the single alkali‐metal ion site proceeds concertedly (the inter‐ligand concerted mechanism), bringing about the benzene C−H activation toward phenol synthesis. The NH3‐driven benzene C−H activation with O2 was compared to the switchover of the reaction pathways from the deep oxidation to selective oxidation of benzene by coexisting NH3 on Pt6 metallic cluster/β and Ni4O4 oxide cluster/β. The NH3‐driven selective oxidation mechanism observed with the Cs+/β and Rb+/β differs from the traditional redox catalysis (Mars‐van Krevelen) mechanism, simple Langmuir‐Hinshelwood mechanism, and acid−base catalysis mechanism involving clearly defined interaction modes. The present catalysis concept opens a new way for catalytic selective oxidation processes involving direct phenol synthesis.

Published: July 2019

AbstractEnabling and empowering the diverse energy resources to have active yet efficient participation in the smart grid and energy market is an unrivaled challenge for the energy industry. This research expands the four dominant archetypes of business models in the energy and electricity market, creating a fifth archetype, the “blockchain marketplace”. The contributions of the study are to identify the extant electricity market designs and architectures as centralized and pseudo-decentralized while proposing a fully decentralized architecture enabled by the blockchain. The research contributes to the literature of smart grids and demand-side management and introduces the value configuration/architecture approach for the energy market and business model domains.
Ethics as a Fabric: An Emotional Reflexive Sensemaking Process
Authors: Fatien Diochon Pauline , Nizet Jean 
Published: July 2019

ABSTRACT:The ethical sensemaking approach stands as an essential alternative to the dominant rational and objectivist paradigm of ethical decision-making in organizations. From this perspective, this research explores the intrapersonal interplay of emotions and reflexivity in ethical sensemaking. We analyzed thirty-seven semi-structured interviews conducted with executive coaches sharing a critical incident about an issue they framed as ethical. Our findings show that their ethical decisions unfolded over a three-phase emotional reflexive sensemaking process, where reflexivity allowed for the management of emotions in the form of emotional awareness, emotional unpacking, and emotional (dis)engagement. Therefore, we portray ethics as afabric, produced through the knitting of emotions and reflexivity. And, while ethics certainly appear to be produced by the subject, we suggest a reciprocal relationship, whereby the very fabric of ethics contributes to the production of the ethical subject.
A Discursive Void in a Cross-Language Study on Russia: Strategies for Negotiating Shared Meaning
Authors: Outila Virpi , Piekkari Rebecca , Mihailova Irina 
Published: July 2019

ABSTRACTDiscursive voids in emerging markets present opportunities and challenges to debate meanings and taken-for granted assumptions. This article uncovers various strategies used by the researcher and the research participants to address the discursive void and to negotiate shared meaning about employee empowerment in Russia. In the absence of a concept for empowerment in the languages of the study, the researcher and the research participants engaged in joint sensemaking to bridge discursive voids. We contribute to the discussion of qualitative cross-language research in emerging markets by identifying the strategies used not only by the researcher, whose view has dominated previous research, but also those of the research participants. The researcher in our study addressed the discursive void by taking on the dual role of researcher-translator, engaging in contextual approach to translation, consulting external interpreters, and using iteration and flexibility in the course of the research process. Our research participants resorted to proverbs to address the discursive void, make sense of empowerment, and render it locally meaningful. Proverbs are a valuable methodological tool for sensemaking and theorising about context-specific phenomena in IB research.
Reflecting and Integrating the Contextual Influences of Ambiguities and Institutional Power in Organisational Research Design: A Case of Myanmar
Authors: Win Sandar , Kofinas Alexander K. 
Published: July 2019

ABSTRACTOur understanding of how an organisation operates is elucidated by the host country's political system. Myanmar has remained abstruse to researchers for many decades, as do most emerging markets prior to their transition from a centrally planned economy to a market economy such as China. We establish how the problematising and contextualisation of the methodologies adopted during longitudinal fieldwork in Myanmar (2008 to 2016) has influenced our research focus and question. By reflecting on our experience of conducting organisational research in a highly institutionalised environment, we have identified limitations in the prevalent research methodologies used by the extant literature. Such methodologies tend to be incompatible with the Asian context. This process of problematisation required us to remain flexible and adaptive during the process of the generation of the research questions. We adopted a context-informed theory-building process and reflect on the interplay between interviewer, interviewees, and local institutional contexts. An important insight from this process was the need to nullify the asymmetry of power between the interviewer and interviewees to obtain honest responses rather than superficial data that aimed to satisfy and please the interviewer/institutional context.
The Color of Faults Depends on the Lens: MNCs’ Legitimacy
Repair in Response to Framing by Local Governments in China

Published: July 2019

ABSTRACTConcerns over food safety in China not only direct public attention to negative
incidents, but also trigger the government's scrutiny of implicated
firms, particularly MNCs. The question of how to repair legitimacy after media
coverage of negative incidents has become a critical issue for MNCs. Although
the factors for MNCs’ public crises have been identified, how local
contexts and mechanisms shape repair approaches remain unclear. To address this
research gap, we conducted a study of Walmart China's approaches
associated with two negative incidents across two regions. We found that the
negative incidents can be framed differently depending on the local
environment's unfavorability for MNCs. Specifically, the negative
framing gave rise to varying degrees of legitimacy loss and offered different
leeway for MNCs to repair their legitimacy. We also identified the varied
outcomes of different repair approaches. By revealing the linkages among local
context, framing, legitimacy repair, and its outcomes, our study contributes to
research on MNCs’ legitimacy management under institutional
complexity and underscores the China context for legitimacy maintenance. We also
offer insights that advance the institutional approach to legitimacy repair in
this context. Last, we reflect on the techniques for conducting qualitative
research in China.

AbstractThe present study investigated the effects of nutritional programming through parental feeding on offspring performance and expression of selected genes related to stress resistance in a marine teleost. Gilthead seabream broodstock were fed diets containing various fish oil (FO)/vegetable oil ratios to determine their effects on offspring performance along embryogenesis, larval development and juvenile on-growing periods. Increased substitution of dietary FO by linseed oil (LO) up to 80 % LO significantly reduced the total number of eggs produced by kg per female per spawn. Moreover, at 30 d after hatching, parental feeding with increasing LO up to 80 % led to up-regulation of the fatty acyl desaturase 2 gene (fads2) that was correlated with the increase in conversion rates of related PUFA. Besides, cyclo-oxygenase 2 (cox2) and TNF-α (tnf-α) gene expression was also up-regulated by the increase in LO in broodstock diets up to 60 or 80 %, respectively. When 4-month-old offspring were challenged with diets having different levels of FO, the lowest growth was found in juveniles from broodstock fed 100 % FO. An increase in LO levels in the broodstock diet up to 60LO raised LC-PUFA levels in the juveniles, regardless of the juvenile’s diet. The results showed that it is possible to nutritionally programme gilthead seabream offspring through the modification of the fatty acid profiles of parental diets to improve the growth performance of juveniles fed low FO diets, inducing long-term changes in PUFA metabolism with up-regulation offads2expression. The present study provided the first pieces of evidence of the up-regulation of immune system-related genes in the offspring of parents fed increased FO replacement by LO.

AbstractBiochar has received attention due to its potential for mitigating climate change through carbon sequestration in soil and improving soil quality and crop productivity. This study evaluated the effects of rice straw biochar (RSB) and rice husk ash (RHA) each applied at 5 Mg ha−1and four N levels (0, 40, 80, and 120 kg ha−1) on soil fertility, growth, and yield of rice and wheat for three consecutive rice–wheat rotations. RSB significantly increased electrical conductivity, dehydrogenase activity, and P and K contents when compared to control (no amendment) up to 7.5 cm soil depth. Both RSB and RHA did not influence shoot N concentration in wheat plant but significantly increased P and K concentrations at 60 days after sowing. Grain yields of both rice and wheat were significantly higher in RSB as compared to control (no amendment) and RHA treatments. While the highest grain yields of rice and wheat were observed at 120 kg N ha−1in RHA and no biochar-treated plots, a significant increase in grain yields was observed at 80 kg N ha−1in RSB treatment, thereby saving 40 kg N ha−1in each crop. Both agronomic and recovery N efficiencies in rice and wheat were significantly higher in RSB-amended soil compared to control. Significant positive correlations were observed between soil N, P, and K concentrations and total N, P, and K concentrations in aboveground biomass of wheat at 60 days after sowing. This study showed the potential benefits of applying RSB for improving soil fertility and yields of rice and wheat in a rice–wheat system.

Published: July 2019

AbstractBackgroundEndoscopic ear surgery is a technique that is growing in popularity. It has potential advantages in the low-resource setting for teaching and training, for the relative ease of transporting and storing the surgical equipment and for telemedicine roles. There may also be advantages to the patient, with reduced post-operative pain, facilitating the ability to complete procedures as out-patients.MethodsOur Ear Trainer has previously been validated for headlight and microscope otology skills, including foreign body removal and ventilation tube insertion, in both the high- and low-resource setting. This study aimed to assess the Ear Trainer for similar training and assessment of endoscopic ear surgery skills in the low-resource setting. The study was conducted in Uganda on ENT trainees.ResultsDespite a lack of prior experience with endoscopes, with limited practice time most participants showed improvements in: efficiency of instrument movement, steadiness of the camera view obtained, overall global rating of the task and performance time (faster task performance).ConclusionThese results indicate that the Ear Trainer is a useful tool in the training and assessment of endoscopic ear surgery skills.

AbstractAngiostrongylus cantonensis is a pathogenic nematode and the cause of neuroangiostrongyliasis, an eosinophilic meningitis more commonly known as rat lungworm disease. Transmission is thought to be primarily due to ingestion of infective third stage larvae (L3) in gastropods, on produce, or in contaminated water. The gold standard to determine the effects of physical and chemical treatments on the infectivity of A. cantonensis L3 larvae is to infect rodents with treated L3 larvae and monitor for infection, but animal studies are laborious and expensive and also raise ethical concerns. This study demonstrates propidium iodide (PI) to be a reliable marker of parasite death and loss of infective potential without adversely affecting the development and future reproduction of live A. cantonensis larvae. PI staining allows evaluation of the efficacy of test substances in vitro, an improvement upon the use of lack of motility as an indicator of death. Some potential applications of this assay include determining the effectiveness of various anthelmintics, vegetable washes, electromagnetic radiation and other treatments intended to kill larvae in the prevention and treatment of neuroangiostrongyliasis.
Getting out of the house: the use of community transport as a third place for rural-dwelling older adults
Authors: Hagan Robert J. 
Published: July 2019

AbstractRural-dwelling older adults experience significant shrinkage in their social networks and capital due to transitions in later life related to poor physical health, mobility difficulties and bereavements. Being rurally located adds an extra layer of disadvantage. This article explores how older adults may use community transport systems to not only facilitate important social tasks but also maintain friendships and other valued relationships. Semi-structured interviews were carried out with 11 users of a rural transport community bus service in western Northern Ireland. The interviews identified that participants viewed the transport system as a highly valued conduit for helping escape isolation, maintaining autonomy, and providing an informal space for relationship building and accessing local news.
Filial piety and intergenerational ambivalence among mother–adult child dyads in rural China

Published: July 2019

AbstractThis study examines the relationship between filial piety (adult children's filial behaviours and attitudes as well as elderly mothers’ overall evaluation of children's filial piety) and elderly mothers’ reports of intergenerational ambivalence (positive feelings, negative feelings and combined ambivalence) in rural China. We analysed the data from a survey in 2016 covering 2,203 adult children and 802 elderly mothers in Sichuan Province using a two-level mixed-effects modelling analysis. The results indicate that most components of filial piety are associated with mothers’ ambivalence, in that less ambivalence was reported by mothers when their adult children provided more emotional support to, had less conflict with and were evaluated as more filial by their mothers. Interestingly, mothers demonstrated greater positive feelings when their children were more filial in behaviour and attitude, but they also reported greater negative feelings and ambivalence when their children were more obedient, implying that absolute obedience to elderly parents might no longer be accepted by people. These findings may provide further understanding about the correlation between the culture of filial piety and intergenerational relationships in rural China.
‘It's most of my life – going to the pub or the group’: the social networks of involuntarily childless older men
Authors: Hadley Robin A. 
Published: July 2019

AbstractThe social networks of older people are a significant influence on their health and wellbeing. Adult children are an important element in their parent's network and provide the majority of informal care. The morphology of personal networks alters with age, employment, gender and relationships. Not having children automatically reduces both vertical familial structure and affects the wider formal and informal social links that children can bring. Childless men are missing from gerontological, reproduction, sociological and psychological research. These fields have all mainly focused on family and women. This paper reports on an auto/biographical qualitative study framed by biographical, feminist, gerontological and lifecourse approaches. Data were gathered from semi-structured biographical interviews with 14 self-defined involuntarily childless men aged between 49 and 82 years old. A latent thematic analysis highlighted the complex intersections between childlessness and individual agency, relationships and socio-cultural structures. The impact of major lifecourse events and non-events had significant implications for how childless people perform and view their social and self-identity. I argue that involuntary childlessness affects the social, emotional and relational aspects of men's lived experience across the lifecourse.
Disability-adjusted life years for severe acute malnutrition: implications of alternative model specifications
Authors: Puett Chloe , Bulti Assaye , Myatt Mark 
Published: July 2019

AbstractObjective:Reducing the burden of childhood severe acute malnutrition (SAM) is key to improving global child health outcomes. Assessing cost-effectiveness of nutrition interventions remains an important evidence gap. Disability-adjusted life years (DALYs) are a common indicator used in cost-effectiveness analyses. DALYs were established by the Global Burden of Disease (GBD) study. Recent iterations of the GBD have changed the methods used to calculate DALYs by dropping age-weighting and discounting (AD) and updating disability weights (DW). Cost-effectiveness analyses may use either local or international standard life expectancies (LE). Changes in model specifications for calculating DALYs may have implications for cost-effectiveness analyses using DALYs, interpreting historical DALY estimates, and related resource allocation decisions. The present study aimed to quantify the magnitude of change in estimates of DALYs attributable to SAM given recent methodological changes.Design:From secondary data analysis, using parameter values from routine programme monitoring data for two SAM treatment programmes and published literature, eight calculation models were created to estimate DALYs with and without AD, using different sets of DW, and local v. standard LE.Results:Different DW had a marginal effect on DALY estimates. Different LE had a small effect when AD was used, but a large effect when AD was not used.Conclusions:DALY estimates are sensitive to the model used. This complicates comparisons between studies using different models and needs to be accounted for in decision making. It seems sensible for analyses to report results using models with and without AD and using local and standard LE.
