Convergent evolution and structural adaptation to the deep ocean in the protein folding chaperonin CCTα
Authors: Weber Alexandra A.-T. , Hugall Andrew F. , O’Hara Timothy D. 
Published: January 2020

AbstractThe deep ocean is the largest biome on Earth and yet it is among the least studied environments of our planet. Life at great depths requires several specific adaptations, however their molecular mechanisms remain understudied. We examined patterns of positive selection in 416 genes from four brittle star (Ophiuroidea) families displaying replicated events of deep-sea colonization (288 individuals from 216 species). We found consistent signatures of molecular convergence in functions related to protein biogenesis, including protein folding and translation. Five genes were recurrently positively selected, including CCTα (Chaperonin Containing TCP-1 subunit α), which is essential for protein folding. Molecular convergence was detected at the functional and gene levels but not at the amino-acid level. Pressure-adapted proteins are expected to display higher stability to counteract the effects of denaturation. We thus examinedin silicolocal protein stability of CCTα across the ophiuroid tree of life (967 individuals from 725 species) in a phylogenetically-corrected context and found that deep sea-adapted proteins display higher stability within and next to the substrate-binding region, which was confirmed byin silicoglobal protein stability analyses. This suggests that CCTα not only displays structural but also functional adaptations to deep water conditions. The CCT complex is involved in the folding of ∼10% of newly synthesized proteins and has previously been categorized as ‘cold-shock’ protein in numerous eukaryotes. We thus propose that adaptation mechanisms to cold and deep-sea environments may be linked and highlight that efficient protein biogenesis, including protein folding and translation, are key metabolic deep-sea adaptations.
Impacts of the perceived quality by consumers’ of à la carte restaurants on their attitudes and behavioural intentions
Authors: Souki Gustavo Quiroga , Antonialli Luiz Marcelo , Barbosa Álvaro Alexandre da Silveira , Oliveira Alessandro Silva 
Published: January 2020

Purpose
À la carte restaurants have faced increasing challenges in meeting the needs and desires of new food consumers. The purpose of this paper is to propose and test a model for evaluating the consumers’ perceived quality of à la carte restaurants and to review the impact on their attitudes and behavioural intentions.

Design/methodology/approach
A survey was conducted with 508 university students in Brazil, and the data were analysed using structural equation modelling (SEM).

Findings
The results showed that global perceived quality (GPQ), which is a multidimensional construct with nine dimensions, directly impacted emotions, the satisfaction and perceived value by consumers. This satisfaction positively affected word-of-mouth (WOM) communication and the propensity for loyalty. Price did not have a statistically significant impact on customer satisfaction.

Originality/value
This paper, based on the structural model herein proposed and tested, is the most complete of all available articles in the literature about à la carte restaurants, as this study contemplates a greater number of perceived quality factors. In addition, both tangible and intangible perceived quality factors were included in this tested model, which goes beyond what is typically contemplated in other such. Moreover, none of the existing articles in the existing literature simultaneously observed the relationship between perceived quality, positive and negative emotions, price, perceived value, satisfaction, WOM communication and propensity to loyalty. Finally, the questionnaire developed in this study could be used both by academics in future studies and by restaurant managers.
“My life’s blueprint”: publishing critical youth narratives in community-based organizations
Authors: Lee Crystal Chen , Schoonover Nina R. 
Published: January 2020

PurposeThis paper aims to explore how currently underserved young adults engaged in a community-based organization (CBO), Bull City YouthBuild, wrote and published a book together, and how this work impacted them and their communities. Through a critical literacy framework, the research asked: How do students in a community-based writing project demonstrate self-empowerment and agency through narrative writing?Design/methodology/approachThis qualitative case study examined the students’ published narratives. The researchers used ethnographic methods in data collection, and the qualitative data analysis approaches were developed through a critical conceptual framework.FindingsThe students’ narratives expressed self-empowerment and agency in the ways the young adults wrote against a dominant discourse; they wrote about repositioning their lives and redesigning their futures to reveal how they wanted to be externally perceived and to be leaders in their communities. The students expressed how the CBO offered them freedom to write their stories as they found new ways of using their historical and cultural backgrounds to collectively pursue success.Social implicationsThis work offers implications of how CBOs can meet the needs of currently underserved young adults through centering their voices. The authors see the writing process as crucial for student engagement in finding agency and self-empowerment with their words.Originality/valueCritical literacy foregrounds the voices of young adults as they push back against dominant narratives and stereotypes. This research hopes to reveal the intersections between CBOs and the communities they serve to develop literacies that are relevant and meaningful to young adults’ lives.
What culture is your university? Have universities any right to teach entrepreneurialism?
Authors: Bamber Christopher John , Elezi Enis 
Published: January 2020

PurposeThe purpose of this paper is to discuss the need for universities to develop an entrepreneurial culture and assess higher education practitioners’ opinions of the culture of the university they are working in.Design/methodology/approachThe research provides empirical data collected through a survey instrument originally used for a PhD research study; however, this paper focuses on the question set related to culture, which was based on the organisational culture model presented by Quinn in 1988.FindingsThe findings indicate that a number of respondents reported from a heterogeneous population of higher education institutes predominantly responded they were working within a hierarchy cultural type with many reporting a market cultural type. While respondents from a homogeneous group from a single university reported in the main they were working in a market-driven cultural type with the next main category being a clan culture.Research limitations/implicationsThe study population reported in the main that there is predominantly a market culture in UK universities. However, this research has focussed entirely on respondents working within the UK HE sector, thus, has ignored potential differences that could be present within the global HE emerging markets.Originality/valueThe paper strengthens understanding of the critical importance of innovation and entrepreneurship in universities. Students, scholars, HE policy makers and HE practitioners can gather a range of insights pointed at university culture and rest assured in the main they are market focussed.
Proposed evacuation safety index (ESI) for school buildings
Authors: Cariño Jan Mae Nigos , Garciano Lessandro Estelito O. 
Published: January 2020

Purpose
Schools are vulnerable to strong-magnitude earthquakes. The purpose of this study is to develop a seismic evacuation safety index (ESI) to assess school’s safety as a function of the following parameters: means of egress, disaster preparedness and disaster response. Moreover, the study aims to simulate and study an evacuation model to estimate evacuation time for a realistic understanding of the evacuation processes.

Design/methodology/approach
The paper used a semi-quantitative risk assessment method in developing the ESI. This was used to evaluate schools and classify them according to their level of evacuation safety. To estimate the evacuation time of each school, cellular automata theory and static floor field were used.

Findings
The paper provides primary school stakeholders important parameters that they should consider in preparing pre-disaster plans to ensure safe evacuation of school children.

Research limitations/implications
ESI focuses only on the means of egress, disaster preparedness and disaster response as the contributing factors. The structural conditions of each school building and assessment of non-structural elements are not considered.

Practical implications
The ESI and the evacuation model can be used as a basis for evacuation planning and decision-making. This can help building owners and administrators in strengthening their disaster risk management plan by enforcing mitigating measures.

Originality/value
ESI is an original idea and fills the gap regarding the safe evacuation of school children especially during a major seismic event.
Vulnerability assessment of reinforced concrete buildings in Indonesia subjected to tsunami inundation forces
Authors: Hanggara Dicky , Wijeyewickrema Anil Christopher 
Published: January 2020

Purpose
This paper aims to evaluate the vulnerability of typical low-rise reinforced concrete (RC) buildings located in Indonesia subjected to tsunami loading.

Design/methodology/approach
The vulnerability of typical three-story RC buildings located in Indonesia subjected to tsunami loading is discussed using fragility curves. Buildings without openings in all stories and buildings with openings in the first story are considered. The fragility curves are obtained by performing tsunami pushover analysis for several load cases, using different tsunami load estimation standards and references. The generalized linear method is used as a curve fitting method to construct the fragility curves.

Findings
The fragility curves show that the three-story RC buildings without openings in all stories subjected to tsunami loading have a high probability of collapse. Openings in the first story will reduce the vulnerability of the buildings.

Originality/value
Fragility curves are obtained by carrying out tsunami pushover analysis to evaluate the vulnerability of typical three-story RC buildings located in Indonesia. The results of this study show the need to include tsunami loads in the design code for Indonesian buildings and the benefits of having openings in the first story of the building.

Authors: Abdelhafidi Nedjma , Bachari Nour El Islam , Abdelhafidi Zohra , Cheknane Ali , Mokhnache Abdelmotaleb , Castro Loranzo 
Published: January 2020

Purpose
Integrated solar combined cycle (ISCC) using parabolic trough collector (PTC) technology is a new power plant that has been installed in few countries to benefit from the use of hybrid solar-gas systems. The purpose of this paper is to investigate the challenges in modeling the thermal output of the hybrid solar-gas power plant and to analyze the factors that influence them.

Design/methodology/approach
To validate the proposal, a study was conducted on a test stand in situ and based on the statistical analysis of meteorological data of the year 2017. Such data have been brought from Abener hybrid solar-gas central of Hassi R’mel and used as an input of our model.

Findings
The proposal made by the authors has been simulated using MATLAB environment. The simulation results show that the net solar electricity reaches 18 per cent in June, 15 per cent in March and September, while it cannot exceed 8 per cent in December. Moreover, it shows that the power plant responses sensibly to solar energy, where the electricity output increases accordingly to the solar radiation increase. This increase in efficiency results in better economic utilization of the solar PTC equipment in such kind of hybrid solar-gas power plant.

Practical implications
The obtained results would be expected to provide the possibility for designing other power plants in Algeria when such conditions are met (high DNI, low wind speed, water and natural-gas availability).

Originality/value
This paper presents a new model able to predict the thermal solar energy and the net solar-electricity efficiency of such kind solar hybrid power plant.
Sport event tourists’ (SET’s) behavior: a case study of the PyeongChang Winter Olympics
Authors: Park Jinwoo , Kim Minhong , Nauright John , Kim Young Hoon 
Published: January 2020

Purpose
The purpose of this paper is to examine the relationships among athlete star power, enjoyment and revisit intention of sport event tourists in a sport mega-event (SME).

Design/methodology/approach
This study was conducted in the context of 2018 PyeongChang Winter Olympic Games. A total of 419 respondents completed a survey. Structural equation modeling was used to analyze the data.

Findings
This study proved the final structure model fit well by having the values and scores higher than the minimum cutoff in all categories. Path coefficients indicate that H1a, H1c and H2 were supported while H1b was not supported by the analysis. In addition, enjoyment partially mediated the relationship between athlete star power and revisit intentions. In particular, two mediating effects were found: enjoyment mediated trustworthiness and revisit intention and expertise and revisit intention. However, enjoyment did not mediate the relationship between attractiveness and revisit intentions.

Research limitations/implications
The limitation of this study lies within two perspectives. Since the data have been collected in one country, the results may be viewed and interpreted for a specific location and time. Thus, it is strongly recommended to conduct the similar studies in the future Olympic Games. In the other perspective, the results could be different from one to another sport game because of the popularity by star power and game itself.

Originality/value
This study adds the literature on sport event research. Although there were a few studies on the effect of athlete star power, a dearth of research examined the relationships among athlete star power (trustworthiness, attractiveness and expertise), enjoyment and revisit intention. These results are valuable to SME managers to increase the propensity of tourists’ revisit intention at sport mega-event by understanding the factors that lead to increased tourist enjoyment.
Financial risk attitudes and aging in Australia
Authors: Kesavayuth Dusanee , Myat Ko Kaung , Zikos Vasileios 
Published: January 2020

AbstractA number of empirical studies document that people tend to become more risk averse as they get older. But other studies find only little evidence that age matters for financial risk attitudes. This prompts a call for revisiting the relationship between age and risk attitude to better support policy recommendations. The current paper contributes to this effort by utilising large‐scale population data to conduct a dynamic panel analysis. Care is taken to avoid the problem of endogeneity of lagged risk attitude in modelling its effects. Analysis reveals that individuals' past risk attitude has a positive effect on their current risk attitude. However, there is only little evidence that risk attitude and age are systematically related. Our results shed some light on the previous contradictory empirical findings in the literature and suggest that past risk attitude is potentially of greater relevance than chronological age in determining current risk attitude.
Maternal Mortality and Public Health Programs: Evidence from Florida
Authors: BERNET PATRICK , GUMUS GULCIN , VISHWASRAO SHARMILA 
Published: January 2020

Policy Points
US maternal mortality rates (MMRs) display considerable racial disparities and exceed those of other developed countries. While worldwide MMRs have dropped sharply since the 1990s, the US MMR appears to be rising.
We provide strong evidence of the effectiveness of pregnancy‐related public health spending on improvements in maternal health.
Using longitudinal data from Florida counties, we found that spending on public health significantly reduced the MMR among black mothers and narrowed black‐white outcome disparities. Each 10% increase in pregnancy‐related public health expenditures was associated with a 13.5% decline in MMR among blacks and a 20.0% reduction in black‐white disparities.
ContextMaternal mortality rates in the United States exceed those of other developed countries. Moreover, these rates show considerable racial disparities, in which black mothers are at three to four times the risk compared with their white counterparts. With more than half of all maternal deaths deemed to be preventable, public health interventions have the potential to improve maternal health along with other pregnancy outcomes. This rigorous longitudinal study examines the impact of a package of pregnancy‐related public health programs on maternal mortality rates.MethodsWe analyzed administrative data on pregnancy‐related public health expenditures, maternal mortality rates, and sociodemographic factors from all 67 Florida counties between 2001 and 2014. Florida provides consistent counts of maternal deaths for the entire period of this analysis. We estimated both fixed‐effects ordinary least squares regressions (OLS) and generalized method of moments (GMM) models. GMM enabled us to identify the impact of public health expenditures on maternal mortality rates while also addressing both potential endogeneity and serial correlation problems. We also provide a series of robustness and falsification tests.FindingsOverall, a 10% increase in targeted public health expenditures led to a weakly significant decline in overall maternal mortality rates of 3.9%. The estimated effect for white mothers was not statistically significant. However, we found statistically significant improvements for black mothers. Specifically, a 10% increase in pregnancy‐related public health spending led to a 13.5% decline in maternal mortality rates among black mothers and a 20.0% reduction in the black‐white maternal mortality gap.ConclusionsOur analysis provides strong evidence of the effectiveness of public health programs in reducing maternal mortality rates and addressing racial disparities.

Published: January 2020

AbstractObjectiveTo examine whether nurse practitioner (NP)‐assigned patients exhibited differences in utilization, costs, and clinical outcomes compared to medical doctor (MD)‐assigned patients.Data SourcesVeterans Affairs (VA) administrative data capturing characteristics, outcomes, and provider assignments of 806 434 VA patients assigned to an MD primary care provider (PCP) who left VA practice between 2010 and 2012.Study DesignWe applied a difference‐in‐difference approach comparing outcomes between patients reassigned to MD and NP PCPs, respectively. We examined measures of outpatient (primary care, specialty care, and mental health) and inpatient (total and ambulatory care sensitive hospitalizations) utilization, costs (outpatient, inpatient and total), and clinical outcomes (control of hemoglobin A1c, LDL, and blood pressure) in the year following reassignment.Principal FindingsCompared to MD‐assigned patients, NP‐assigned patients were less likely to use primary care and specialty care services and incurred fewer total and ambulatory care sensitive hospitalizations. Differences in costs, clinical outcomes, and receipt of diagnostic tests between groups were not statistically significant.ConclusionsPatients reassigned to NPs experienced similar outcomes and incurred less utilization at comparable cost relative to MD patients. NPs may offer a cost‐effective approach to addressing anticipated shortages of primary care physicians.
The real problem: The deadly combination of psychologisation, scientism, and normative promotionalism takes strategic human resource management down a 30‐year dead end
Authors: Kaufman Bruce E. 
Published: January 2020

AbstractThis paper engages with Troth and Guest (2019) on psychology in HRM. I argue they misframe the central issue in debate. The real problem is not psychology per se but psychologisation—the drive to reduce explanation of macro‐level HRM outcomes to individual‐level psychological‐behavioural factors and individual differences. Accordingly, the most visible and harmful effects of psychologisation are in strategic HRM and the HRM‐performance literature but Troth and Guest's defence of psychology does not cover them. I use this response to re‐establish that it is psychologisation, not psychology per se, that is the critics' focal concern and describe how the three‐decade advance of psychologisation, along with scholastic scientism and normative promotionalism, have created severe theoretical and empirical problems in the high‐performance research programme and taken the strategic HRM field down a 30‐year dead‐end. Suggestions for a turn‐around are provided.

AbstractProblemAs more women join the skilled‐trade workforce, the effects of workplace exposures on pregnancy need to be explored. This study aims to identify the effects of mild steel and stainless steel welding fume exposures on cultured placental trophoblast cells.Method of studyWelding fumes (mild steel and stainless steel) were generously donated by Lincoln Electric. Electron microscopy was used to characterize welding fume particle size and the ability of particles to enter extravillous trophoblast cells (HTR‐8/SVneo). Cellular viability, free radical production, cytokine production, and ability of cells to maintain invasive properties were analyzed, respectively, by WST‐1, electron paramagnetic resonance, DCFH‐DA, V‐plex MULTI‐SPOT assay system, and a matrix gel invasion assay.ResultsFor all three welding fume types, average particle size was <210 nm. HTR‐8/SVneo cells internalized welding particles, and nuclear condensation was observed. Cellular viability was significantly decreased at the high dose of 100 µg/mL for all three welding fumes, and stainless steel generated the greatest production of the hydroxyl radical, and intracellular reactive oxygen species. Production of the cytokines IL‐1β and TNFα were not observed in response to welding fume exposure, but IL‐6 and IL‐8 were. Finally, the invasive capability of cells was decreased upon exposure to both mild steel and stainless steel welding fumes.ConclusionWelding fumes are cytotoxic to extravillous trophoblasts, as is evident by the production of free radicals, pro‐inflammatory cytokines, and the observed decrease in invasive capabilities.
