The impact of role ambiguity on future volunteering: A case study of the 2017 European Youth Olympic Winter Festival

ABSTRACT Research on role ambiguity suggests its relationship to retention and commitment in business, industry and non-profit settings. The purpose of this study was to explore factors associated with perceived role ambiguity experienced by volunteers at the 2017 European Youth Olympic Winter Festival, and their impact on future volunteering engagement and awareness post-event. The study also examined differences in event role ambiguity perceptions based on gender, age and volunteering experience among the participants. Data were collected by a means of an online-administered survey from a sample of 268 volunteers. A response rate of 44% was obtained. Results of principal component analysis suggested two role ambiguity factors consisting of ‘means-ends/expectations & Scope’ and ‘Consequences of role performance’ that were relevant in this event setting. A significant association between volunteering experience and both role ambiguity dimensions were reported, while for ‘means-ends/expectations & scope’ ambiguity, males experienced greater clarity. Finally, the results indicate that role ambiguity is associated with future volunteering beyond the event. Implications for event managers are then explored.
Effect of catalyst type on molecular weight increase and coloration of poly(ethylene furanoate) biobased polyester during melt polycondensation

In this work, the effect of the catalysts tetrabutyl titanate(IV) (TBT), titanium(IV) isopropoxide (TIS), tin(II) 2-ethylhexanoate (TEH) and dibutyltin(IV) oxide (DBTO) on the synthesis of poly(ethylene furanoate) (PEF) was studied during a two-stage melt polycondensation process. In all reactions, 2,5-dimethylfuran-dicarboxylate (DMFD) and ethylene glycol (EG) in 1 : 2 molar ratios, and 400 ppm of catalyst were used. The rate of the transesterification reaction (first stage) was evaluated by measuring the volume of the distilled methanol and for the polycondensation reaction (second stage) by the increase of intrinsic viscosity. For the first stage, all catalysts had a similar effect to methanol distillation, except for TEH which was found to be the slowest catalyst, while for the second stage TIS and TBT were found to be the most effective catalysts, followed by DBTO and TEH, which again had the lowest reactivity. Coloration of the prepared polyesters was measured using the L*a*b* colour space system and was found to be dependent on catalyst type and melt polycondensation time, with titanate catalysts yielding the highest coloration. White coloured polyesters can be obtained after dissolution in trifluroacetic acid and chloroform mixture, and precipitation in methanol. Decomposition by-products formed throughout the different processes were identified in solution and elucidated by using liquid chromatography high resolution mass spectrometry (LC-HRMS). Similar decomposition products were detected in all chromatographs and therefore concentration in samples prepared with titanate catalysts might be the cause of the higher colour intensity of these samples.
Meaning-Making Coping With COVID-19 in Academic Settings: The Case of Sweden

In this study, we map and describe the coping methods used by members of the university community in Sweden to deal with the first wave of the coronavirus pandemic. This study, which used simple random sampling, was quantitative. It employed a modified version of the RCOPE instrument as well as items from earlier studies of meaning-making coping in Sweden. Among participants (n = 277, 64% women), the most frequently used coping method was nature as a resource in dealing with stress and sadness, followed by listening to the sounds of surrounding nature and thinking of life as part of a greater whole; these coping methods were the most common in all subgroups studied. We used a cultural perspective to better understand the application of certain meaning-making coping methods.
Geometric Optimization of an Extracorporeal Centrifugal Blood Pump with an Unshrouded Impeller Concerning Both Hydraulic Performance and Shear Stress

Centrifugal blood pumps have provided a powerful artificial support system for patients with vascular diseases. In the design process, geometrical optimization is usually needed to acquire a more biocompatible model for clinical uses. In the current paper, we propose a method for multi-objective optimization concerning both the hydraulic and the hemolytic performances of the pump based on the near-orthogonal array in which the traditional hemolysis index (HI) is replaced with the maximum scalar shear stress criteria to reduce the computation load. The method is demonstrated with the optimization of an extracorporeal centrifugal blood pump with an unshrouded impeller. CFD studies on the original and nine modified pump models are carried out. The calculated hydraulic performances of the optimized model are also compared against the experiments for validation of the numeric method, with an error of 3.6% at the original design point. The resulting blood pump with low maximum scalar shear stress (132.2 Pa) shows a low degree of calculated HI (1.69 × 10−3).
Teachers’ professional collaboration and trust relationships: An inferential social network analysis of teacher teams

In recent years, teachers around the world have been increasingly confronted with various expectations concerning the improvement of their classroom practices and school activities. One factor widely acknowledged to facilitate school and classroom improvement is a strong collaborative culture among teachers. As such, teachers are expected to work in teacher teams, to collaborate closely with colleagues, to co-construct classroom practices, and thus to strengthen trust relationships within the team. A growing number of researchers has analyzed how teachers address these expectations. They suggest that there is a link between teachers’ embeddedness in collaboration networks and teachers’ trust relationships. The present study seeks to contribute to the research literature by presenting results of Social Network Analyses (SNA) and exponential random graph models (ERGMs) on teacher collaboration in nine secondary schools in Germany (N = 366 teachers). We investigate how the involvement of teachers in co-constructive collaboration in schools, measured by the amount of team teaching (TT), relates to teachers’ trust levels. Results of our analyses suggest that a high amount of TT is not necessarily related to a higher degree of trust among teachers at the school level. However, a high involvement of teachers in TT is related positively to their being perceived as trustworthy. Furthermore, the emergence of trust relations in teacher networks depends on general network characteristics, such as homophily, reciprocity and transitivity.
Systemic Sarcoidosis: Sociodemographic and Genetic Characteristics in a Tunisian Population

Sarcoidosis is a multi-systemic granulomatosis of unknown cause, characterized by a clinical polymorphism. It results from interplay of environmental and genetic factors. The aim of our study was to describe sociodemographic and genetic characteristics in Tunisian patients with sarcoidosis. We conducted a retrorospective study of patients with sarcoidosis followed in the internal medicine and neurology departments at the Military Hospital of Tunis. We collected epidemiological characteristics. Genetic study concerned only patients who accepted to participate. DNA extraction was performed from whole blood. HLA class II typing and gene mutation testing of the ACE gene were also performed. Our study concerned 50 patients. The mediastino-pulmonary involvement was the most frequent (72.3%), followed by neurological involvement (58.5%), cutaneous involvement (50.8%) and ophthalmological involvement (40%). Genetic analysis showed a high frequency of the HLA DRB1 * 1501 allele (38%), DD genotype (30%) and D allele (54%) of the ACE gene. Treatment with corticosteroids was most often used 73.85%. The evolution was favorable in 13 cases (26.15%), and stable in 63% of cases. In conclusion, sociodemographic and genetic characteristic are variable from one ethnic to another. Advances in genotyping and statistical analysis are helping to elucidate the genetics of sarcoidosis.
Reply to reviewers

Unstable atmospheric conditions are often observed during the daytime over land and for significant periods offshore, and are hence relevant for wake studies. A simple k-ε RANS turbulence model for simulation of wind turbine wakes in the unstable surface layer is presented, which is based on Monin-Obukhov similarity theory (MOST). The turbulence model parametrizes buoyant production of turbulent kinetic energy (TKE) without the use of an active temperature equation, and flow balance is ensured throughout the domain by modifications of the turbulence transport equations. Large eddy simulations and 5 experimental data from the literature are used for validation of the model.
Can Workplace Fun Moderate Organizational Identification and Job Satisfaction Relationship

Job satisfaction is critical to the changing and growing challenges of the service sector. The present research study investigates the moderation effect of workplace fun on the relationship between organizational identification (OID) and job satisfaction. The sample was 220 frontline employees in 57 hotels in Nigeria. We found that OID positively influenced job satisfaction. Additionally, workplace fun moderated the effect of OID onjob satisfaction. The findings suggest that organizational leaders can use fun to generate favorable organizational outcomes. We also found that OID promotes workplace fun, which, in turn, results in high job satisfaction. The implication is that when employees feel a sense of oneness within an organization, they will effectively define their work roles and feel accountable for the decision. Organizations that want to inspire positive customer relation behaviors should encourage employees’ OID and implement friendly workplace practices. The study added twofold values to this research area. We explore OID and workplace fun. The study also explores the moderation effect of workplace fun on the relationship between OID and job satisfaction. Thus, managers can increase employee job satisfaction by encouraging workplace fun.
Game variables that predict success and performance level in elite men’s volleyball

ABSTRACT This study examined the Men’s European Volleyball Championship 2019 in which 24 national teams competed. The sample was split into three groups according to its team final ranking. The effectiveness of the main volleyball skills, such as serve, reception, attack after reception, attack after defence and block was calculated. The success rates of each team in side-out and breakpoint complexes were also computed. The reliability of the analysis was examined with Cohen’s Kappa score. Two stepwise discriminant analyses were performed to identify the contribution of each skill’s effectiveness and each complex success rate to winning in a volleyball set and the team’s classification. Cross-validation results showed that the discriminant function correctly classified 91.1% of the teams’ performance in win-lose sets and 83.3% of the teams’ performance level. The variables which were considered to be central in defining discriminant dimension were break point win(BPwin) = . 755 and effectiveness of attack after reception (A1E) = . 484 for win-lose sets, and BPwin = . 534 and A1E = . 454 for performance level, respectively. The results of the study indicate that success in volleyball in a typical set or a tournament can be explained with two performance indicators: the effectiveness of attack after reception and the success rate of breakpoint complex.
Effectiveness of a Hybrid Project-Based Learning (H-PBL) Approach for Students’ Knowledge Gain and Satisfaction in a Plant Tissue Culture Course

The main objective of the present study was to evaluate the effectiveness of two learning methodologies in a Plant Tissue Culture course of a Biotechnology degree—lecture-based and hybrid project-based learning—in which a project assignment was included. The effectiveness of these two systems was compared based on the students’ knowledge acquisition and the perception of their satisfaction. In this study, we evaluated the scores obtained by students in a written exam and the results of a satisfaction survey. The assessment showed that students attained improved marks in the written exam after being taught using the hybrid method. The incorporation of the project assignment in the Plant Tissue Culture program also improved the general perception that the students had of the course. The project assignment allowed the students to achieve new learning outcomes directly related to experimental work and the scientific method. The teachers perceived the hybrid project-based learning method positively, as students not only improved their knowledge gain, but were also more involved in the course.
Sensory profiles and consumer acceptance of different styles of Australian Moscato

Background and Aims In recent years, there has been significant growth in the popularity, and therefore sales, of Moscato in Australia. The aim of this study was to determine the sensory and quality variation amongst Australian Moscato wines, as well as consumer acceptance of different styles of Moscato. Methods and Results The sensory profile of 24 Australian Moscato wines was determined by descriptive analysis using a trained panel, while quality ratings were determined by an expert panel of sparkling winemakers and wine show judges. Statistical analysis of sensory attribute ratings facilitated selection of a subset of Moscato wines, comprising three white and three pink wine styles that reflected the sensory variation observed amongst all wines, which were subsequently used in acceptance trials to determine consumer liking. Conclusions Considerable diversity was observed amongst the composition and sensory profiles of the Moscato wines studied, with some exhibiting more prominent varietal characters, while others displayed complex, developed notes. Mean hedonic ratings for the subset of Moscato wines ranged from 4.7 to 5.6 (on a 9 cm scale). Segmentation of consumers according to their individual liking scores enabled identification of two consumer clusters with opposing preferences for distinct styles of Moscato. Significance of the Study The variation in sensory profiles and quality of Australian Moscato wines has been profiled for the first time and consumer acceptance of different styles of Moscato determined. These results enable industry to make more informed decisions with regard to wine production and marketing, that is, to tailor different styles of Moscato for specific segments of the domestic sparkling wine market.
The Relation between Vocational Commitment and Need Fulfillment in Real Time Experiences in Clinical Internships

ABSTRACT This study concerns the question how specific characteristics of real-time experiences relate to commitment change. The focus is on the real-time fulfillment of the basic needs: the need for competence, for relatedness and for autonomy. The research question was: “What is the relation between real time need fulfillment and commitment in psychology students during their practical internships? ” The participants were 56 master students who did a five-month clinical internship in psychology. The participants wrote at least 19 weekly diary reports (in a period of 5 months) about the most important experience in their internship in that week, and in addition they filled in a short questionnaire. With a linear mixed model analysis, the relation was analyzed between need fulfillment and commitment on an individual and on a group level. The basic needs were found to be a relevant characteristic of experiences: need fulfillment or need frustration was described in by far most experiences. Experiences with a positive need fulfillment were related to higher levels of commitment strength than experiences that concerned frustration of need fulfillment, or that did not report need fulfillment. This pattern of relations was found in 90% of the individual participants. The experiences of the atypical 10% of the participants reflected a non-optimal relationship with their internship or supervisor.
Osteological characters for the identification of Caribbean columbids

Columbid remains are commonly recovered from Caribbean archaeological and paleontological sites. Identifying specimens to species level is therefore likely to yield a wealth of information concerning species diversity and changes in their distribution over time. Here we examine the metrical data and 42 osteological characters of eight skeletal elements of 80 specimens belonging to 12 species from five genera that represent most of the indigenous taxa of the West Indies. Our new data provide a reliable means for identifying these birds in the Caribbean fossil and subfossil record.
Does undertaking genome sequencing prompt actual and planned lifestyle-related behavior change in cancer patients and survivors? A qualitative study

Abstract Background: In order for genomic testing to fulfil its promise of helping cancer patients and survivors to prevent future disease, it is important to consider its behavioral impact and outcomes. This study explored the factors that participants perceived would impact lifestyle-related behavioral intentions following genome sequencing (GS). Methods: Individual semistructured interviews were conducted to explore behavioral intentions with a purposive subsample of 24 adults with a past or current cancer of likely heritable aetiology who undertook germline GS as part of a larger genetic study (RisC). Participants were interviewed 12 months following their consent to a longitudinal psychosocial sub-study of RisC (PiGeOn study), before receipt of results. Data were analyzed using thematic analysis. Results: Analysis revealed 3 main themes: past prompts, barriers, and motivators to behavior change. The primary goal for behavioral change was to be healthy for oneself and one's family. Past experience of cancer facilitated positive modifications to lifestyle, such as increased exercise and healthy diet, higher prioritization of mental health and well-being, and regular health check-ups and tests. Maintaining these changes, however, was difficult for some due to daily commitments and lack of self-control. Limited knowledge and perceived inevitability of developing cancer due to genetic predisposition were recognized as barriers to making lifestyle changes. Concurrently, future receipt of actionable results was perceived as a powerful driver of behavior change. Conclusion: Understanding barriers and facilitators to behavior intention and patients’ attitudes to recommended lifestyle change in the context of genomic testing can be useful for health care professionals, to guide their discussions of behavioral change.
Occurrence of the bigeye thresher shark, Alopias superciliosus (Lowe, 1841) (Elasmobranchii, Alopiidae) in the southwestern Gulf of Mexico

The bigeye thresher shark Alopias supeciliosus is a large epipelagic and mesopelagic species, and it has a wide distribution in the Atlantic. However, its record in the Gulf of Mexico is sporadic. A single adult female of A. superciliosus, measuring 360 cm total length and about weight 165 kg, was caught by artisanal fishers in Salinas Roca Partida, Veracruz, Mexico, on July 14, 2020. This study reports the first occurrence of this species in the southwestern of the Gulf of Mexico, which extends its geographical distribution in Mexico.
Statistical Uncertainty in Paleoclimate Proxy Reconstructions

A quantitative analysis of any environment older than the instrumental record relies on proxies. Uncertainties associated with proxy reconstructions are often underestimated, which can lead to artificial conflict between different proxies, and between data and models. In this paper, using ordinary least squares linear regression as a common example, we describe a simple, robust and generalizable method for quantifying uncertainty in proxy reconstructions. We highlight the primary controls on the magnitude of uncertainty, and compare this simple estimate to equivalent estimates from Bayesian, nonparametric and fiducial statistical frameworks. We discuss when it may be possible to reduce uncertainties, and conclude that the unexplained variance in the calibration must always feature in the uncertainty in the reconstruction. This directs future research toward explaining as much of the variance in the calibration data as possible. We also advocate for a “data‐forward” approach, that clearly decouples the presentation of proxy data from plausible environmental inferences.
Does organizational justice enhance job performance through high-performance human resource practices?

This study aims to analyze the influence of organizational justice (OJ) on job performance (JP) intention via the mediating influence of high-performance human resource practices (HPHRPs) in a developing context. Equity theory and expectancy theory are widely employed in many disciplines but seldom applied to JP among Pakistan Telecommunication Limited (PTCL) employees. The respondents in this study were 377 employees working in PTCL. Partial least square (PLS), specifically ̣ structural equation modeling was used for the data analysis. The study found a significant direct and indirect influence of distributive justice (DJ) on JP through the partial mediating role of selective staffing (SS) and extensive training (ET). Procedural justice (PJ) also, directly and indirectly, influenced JP through the partial mediating role of the incentive reward (IR). While interactional Justice (IJ), result-oriented appraisal (ROA), employment security (ES) had an insignificant influence on JP. OJ has to be synergized with HPHRPs to enhance JP. The results of this study would also augment the body of knowledge of JP in developed and under-developing countries. OJ has to be synergized with HPHRPs to enhance JP. The results of this study would also argue the body of knowledge of JP in developed and under-developing countries.
