Online listening responses and e-learning performance
Authors: Du Zhao , Wang Fang , Wang Shan , Xiao Xiao 
Published: June 2022

PurposeThis research investigates the impact of learners' non-substantive responses in online course forums, referred to as online listening responses, on e-learning performance. A common type of response in online course forums, online listening responses consist of brief, non-substantive replies/comments (e.g. “agree,” “I see,” “thank you,” “me too”) and non-textual inputs (e.g. post-voting, emoticons) in online discussions. Extant literature on online forum participation focuses on learners' active participation with substantive inputs and overlooks online listening responses. This research, by contrast, stresses the value of online listening responses in e-learning and their heterogeneous effects across learner characteristics. It calls for recognition and encouragement from online instructors and online forum designers to support this activity.Design/methodology/approachThe large-scale proprietary dataset comes from a leading MOOC (massive open online courses) platform in China. The dataset includes 68,126 records of learners in five MOOCs during 2014–2018. An ordinary least squares model is used to analyze the data and test the hypotheses.FindingsOnline listening responses in course forums, along with learners' substantive inputs, positively influence learner performance in online courses. The effects are heterogeneous across learner characteristics, being more prominent for early course registrants, learners with full-time jobs and learners with more e-learning experience, but weaker for female learners.Originality/valueThis research distinguishes learners' brief, non-substantive responses (online listening responses) and substantive inputs (online speaking) as two types of active participation in online forums and provides empirical evidence for the importance of online listening responses in e-learning. It contributes to online forum research by advancing the active-passive dichotomy of online forum participation to a nuanced classification of learner behaviors. It also adds to e-learning research by generating insights into the positive and heterogeneous value of learners' online listening responses to e-learning outcomes. Finally, it enriches online listening research by introducing and examining online listening responses, thereby providing a new avenue to probe online discussions and e-learning performance.

Authors: Vaidya Ranjan , Myers Michael D. 
Published: June 2022

Purpose
This paper aims to highlight the importance of the study of emotions in the successful implementation of information systems projects in developing countries. This paper studies one emotion, namely, anger, and discusses its detrimental impact on information system interventions. This paper suggests that controls are necessary for the management of anger emotion.

Design/methodology/approach
This research study explores the case of an Indian agricultural marketing board that implemented an information systems project on the integration of agricultural markets. The data was collected through semistructured interviews from four stakeholder groups. This paper uses a qualitative approach and analyzes the data using thematic analysis. Pierre Bourdieu’s theory of practice is used to study emotions in the case.

Findings
This paper finds that anger is the prominent emotion displayed at public sector organizations in India. This paper permeates all aspects of public organizations and has a detrimental impact on successfully implementing the information systems projects. Successful implementation of the information systems (IS) projects in India will need to have a framework for managing the anger emotion.

Originality/value
To the best of the authors’ knowledge, this is the first paper within the information systems discipline that focuses on anger and its detrimental impact on successful IS interventions. A unique contribution of this paper is a framework for the study of emotions. This paper also introduces the idea of controls for emotional management.

PurposeThis study aims to advance the bottom-line mentality (BLM) literature by drawing on goal-setting theory to examine the positive effects of supervisor BLM on employees' behavior.Design/methodology/approachThe authors collected survey data from 291 full-time employees from various Chinese organizations at three different points in time.FindingsThe authors found that supervisor BLM and employees' collectivism orientation interacted to influence employees' bottom-line goal commitment such that the positive relationship between supervisor BLM and employees' bottom-line goal commitment was stronger when employees' collectivism orientation was high rather than low. Furthermore, they found that employees' collectivism orientation moderated the positive indirect effects of supervisor BLM on employees' work effort and helping behavior via bottom-line goal commitment such that the indirect effects were stronger when employees had a high rather than a low collectivism orientation.Originality/valueThe authors explored the “bridge side” of supervisor BLM on employees' behavior, especially after being moderated by collectivism orientation. Our results can help managers develop a comprehensive understanding of BLM.
Patterns of phenotypic plasticity along a thermal gradient differ by trait type in an alpine plant

Abstract

Climate change presents many challenges for plants, a major one of which is the steady increase in the temperatures that plants are exposed to during germination, growth and reproduction. Generating a more complete understanding of the capacity for plants to respond and of the role that phenotypic plasticity plays in facilitating species' responses to warming temperatures is a central objective in global change ecology.

Different traits expressed across life stages might be expected to exhibit a variety of responses to temperature due to phenotypic plasticity and genetic variation, even within a species. However, the extent of the variation among trait types and the relative contribution of plasticity and genetics to responses along a thermal gradient are not well understood. Here, we studied an alpine plant, Wahlenbergia ceracea, to determine the shapes of plastic responses in 14 traits across germination, leaf, physiology and reproductive fitness trait types across a broad thermal gradient of temperatures while also comparing responses among family lines.

Trait types differed markedly: germination, leaf and reproductive traits showed nonlinear plasticity with best performance at intermediate temperatures, whereas physiology traits were generally less responsive to temperature. Variation in plasticity among families was lowest for the traits most necessary for tolerating environmental extremes (e.g. heat tolerance), suggesting that physiology traits may be canalised and fitness suffers for it. In contrast, variation in means, and plasticity in some cases, among families in germination traits suggests genetic variation and hence the potential for these few traits to respond to selection.

Our results illustrate the variety of responses that may occur in response to temperature, and the frequent occurrence of complex nonlinear plastic responses that would not have been apparent with comparison of fewer temperatures. We discuss the physiological, ecological and evolutionary insights our findings provide into the response of wild species to the changing climate.

Can fire‐age mosaics really deal with conflicting needs of species? A study using population hotspots of multiple threatened birds
Authors: Verdon Simon J. , Clarke Michael F. 
Published: June 2022

Abstract

Locations that support high densities of a species (‘population hotspots’) often have a disproportionate influence on species' persistence. In fire‐prone ecosystems, managers attempting to promote population hotspots of multiple species must understand how hotspot locations might shift with post‐fire succession and how much overlap exists in the locations of population hotspots for multiple species. Mangers are then tasked with resolving fire‐management conflicts in overlapping locations.

We studied three co‐occurring threatened bird species in a fire‐prone ‘mallee’ region of south‐eastern Australia. We undertook field surveys for each species (1,508 surveys, 540 sites; 9‐ha each). We used N‐mixture models to determine (a) what factors affect species' density (including post‐fire succession); (b) species' population sizes; (c) locations of species' current population hotspots and locations that may become population hotspots in the future as the post‐fire successional state changes and (d) the degree of overlap in the current and possible future hotspots of species.

We found substantial variation in the densities of the three species across the study area, with roughly half of each species' population occurring in only 20% of potential habitat (i.e. population hotspots). All species shared a preference for subtle depressions in the landscape, resulting in substantial overlap in their population hotspots. Two species had contrasting responses to post‐fire succession in the subtle depressions. As a result, there was only a narrow post‐fire period that supported population hotspots of both species, creating a challenge for fire managers in these shared locations.

Synthesis and applications. Many studies make vague recommendations for fire‐age mosaics that do not provide conservation managers with the detail they need to implement appropriate fire‐age mosaics. By contrast, we explicitly quantify, then balance the conflicting post‐fire needs of species in locations that support population hotspots of multiple species. Using this approach, we develop principles to guide the implementation of fire‐age mosaics in such locations. This approach represents an important step towards applying fire‐age mosaic theory to effectively support species conservation.
Ministerial policy dominance in parliamentary democracies
Authors: KLÜSER K. JONATHAN , BREUNIG CHRISTIAN 
Published: June 2022

AbstractTo what extent do ministries dominate a particular policy domain? The policy dictator model and many principle‐agent models of governmental control that followed suit assume that governments create ministries with clear and exclusive policy responsibilities. We test this assertion using data from parliamentary bills from Denmark, Germany, and the Netherlands. For each bill, we observe its substantial policy content and the responsible ministry. The data show that bills on similar issues regularly are drafted by different ministries in parliamentary democracies. About 40 per cent of policy issues cannot be ascribed to one dominant ministry. The regularities elucidate that ministerial division of labour within governments is considerably more complex than commonly assumed. The variegated level of ministerial dominance across policy domains calls for a new research agenda on how governments assign responsibility for legislative action in parliamentary democracies.

Published: June 2022

AbstractBackgroundSurveys of changes in drinking during the COVID‐19 pandemic have primarily relied on retrospective self‐report. Further, most such surveys have not included detailed measures of alcohol use patterns, such as beverage‐specific consumption, nor measures of alcohol use disorder (AUD) symptoms that would allow a comprehensive understanding of changes in alcohol use.MethodsData from 1819 completed interviews from the N14C follow‐up survey to the 2019 to 2020 National Alcohol Survey (N14) were conducted between January 30 and March 28, 2021. Questions on alcohol use from the Graduated Frequency series, beverage‐specific quantity and frequency, and DSM‐5 AUD items were asked in both surveys and used to estimate changes from pre‐pandemic drinking to drinking during the pandemic. Analyses focus on changes in these measures over time and comparisons between key subgroups defined by gender, race/ethnicity, and age.ResultsKey findings include particularly large increases in drinking and AUD for African Americans and women, reduced drinking and heavy drinking prevalence among men and White respondents, and a concentration of increased drinking and AUD among respondents aged 35 to 49. Increases in alcohol use were found to be driven particularly by increases in drinking frequency and the consumption of spirits.ConclusionsResults confirm prior findings of overall increases and subgroup‐specific changes, and importantly, provide detailed information on the patterns of change across major socio‐demographic subgroups. Substantial increases in the prevalence of DSM‐5 moderate to severe AUDs are a novel finding that is of particular concern.

Published: June 2022

AbstractTranslocation and captivity are important tools for conservation biology and wildlife management. Understanding the movement ecology of animals following their release in novel terrain is critical to predicting the success of wildlife restoration efforts. Mountain caribou have high conservation value – efforts to restore their populations across western Canada involve hundreds of millions of dollars in science, monitoring, and management activity. Here, we examined the movements of adult female caribou (N = 36) following their translocation to, and release from, a maternity pen (‘penned caribou’) and compared these movements to animals that were not translocated (‘unpenned caribou’, N = 22). A maternity pen is a temporary holding facility, within the animals’ existing range, that enables them to bear and raise their young in the absence of predators and with augmented resources. Penned and unpenned animals had similar home range sizes (1052.2 and 1314.6 km2, respectively, P = 0.46) though penned animals moved through the landscape in a faster yet less directed manner. We found some evidence that memory may improve the efficiency of space use. Home ranges with higher quality habitats tended to be smaller than home ranges with poorer quality habitats irrespective of penning status. Penned animals ranged at lower elevation (~150 m) than unpenned animals, particularly in spring and early winter. For penned animals, we did not detect evidence of homing back to the original capture site. The best predictor of how caribou will use the landscape appears to be proximity to the location of the release site. To maximize the fitness of released caribou, future plans for maternity pens and captive breeding programs need to consider the management of food, predators, and habitat across the 1000–2000 km2 that will form the home range near the release site.
Citizen science indicates significant range recovery and defines new conservation priorities for Earth's most endangered pinniped in Greece

Published: June 2022

AbstractConservation actions for endangered species often require detailed data over large temporal and spatial scales, which are usually hard to obtain from traditional scientific surveys that operate at localized scales. In contrast to the terrestrial conservation world where citizen science has become nowadays a highly relevant and useful tool to overcome such difficulties, Marine Citizen Science is still highly underrepresented. Using a dataset of 20 years of citizen science data and appropriate statistical modelling, we developed a methodological approach to monitor the presence of the endangered, notoriously elusive Mediterranean monk seal Monachus monachus. We used sighting data collected in Greece from 2000 to 2020 and fitted dynamic occupancy models that allow inferring range dynamics whilst accounting for species imperfect detectability to estimate species occupancy. The occurrence of Mediterranean monk seals of all age categories combined, and pups separately, increased during the study period. Mediterranean monk seal occurrence increased also spatially: the distribution of the species in Greece increased by approximately 12.5% for seals of all age categories and by approximately 185% for monk seal pups. Most of this distribution (i.e. 67 and 72% of the distribution of seals of all age categories and of pups, respectively) was located within the boundaries of the network of protected areas in the country. These results indicate a significant range recovery of the Mediterranean monk seal in Greece over the last two decades and facilitate the prioritization of conservation actions for the species in the country. We demonstrate how occupancy modelling and citizen science can be used to evaluate the distribution of an endangered species and become a highly relevant and reliable tool in marine mammal conservation. We advocate the increased use of citizen science in the conservation of the Mediterranean monk seal in the eastern Mediterranean Sea.

AbstractBackgroundPrevious studies in animal models evidenced that genetic mutations of KATNAL1, resulting in dysfunction of its encoded protein, lead to male infertility through disruption of microtubule remodelling and premature germ cell exfoliation. Subsequent studies in humans also suggested a possible role of KATNAL1 single‐nucleotide polymorphisms in the development of male infertility as a consequence of severe spermatogenic failure.ObjectivesThe main objective of the present study is to evaluate the effect of the common genetic variation of KATNAL1 in a large and phenotypically well‐characterised cohort of infertile men because of severe spermatogenic failure.Materials and methodsA total of 715 infertile men because of severe spermatogenic failure, including 210 severe oligospermia and 505 non‐obstructive azoospermia patients, as well as 1058 unaffected controls were genotyped for three KATNAL1 single‐nucleotide polymorphism taggers (rs2077011, rs7338931 and rs2149971). Case–control association analyses by logistic regression assuming different models and in silico functional characterisation of risk variants were conducted.ResultsGenetic associations were observed between the three analysed taggers and different severe spermatogenic failure groups. However, in all cases, the haplotype model (rs2077011*C | rs7338931*T | rs2149971*A) better explained the observed associations than the three risk alleles independently. This haplotype was associated with non‐obstructive azoospermia (adjusted p = 4.96E‐02, odds ratio = 2.97), Sertoli‐cell only syndrome (adjusted p = 2.83E‐02, odds ratio = 5.16) and testicular sperm extraction unsuccessful outcomes (adjusted p = 8.99E‐04, odds ratio = 6.13). The in silico analyses indicated that the effect on severe spermatogenic failure predisposition could be because of an alteration of the KATNAL1 splicing pattern.ConclusionsSpecific allelic combinations of KATNAL1 genetic polymorphisms may confer a risk of developing severe male infertility phenotypes by favouring the overrepresentation of a short non‐functional transcript isoform in the testis.

AbstractIntroductionFear of childbirth is a well‐known problem during pregnancy and can have implications for childbirth, including prolonged labor, use of epidural analgesia, obstetric complications, presence of traumatic stress symptoms, or request for an elective cesarean section. The coronavirus disease 2019 (COVID‐19) pandemic has affected mental health and therefore could have increased fear of childbirth during the pandemic. The aim of this study was to investigate fear of childbirth during the pandemic in the Netherlands compared with a reference group from before the pandemic.Material and methodsWe conducted a cross‐sectional study to evaluate pregnant women during the first and second waves of COVID‐19 compared with both each other and with pregnant women from before the pandemic. Participants were recruited through social media platforms, hospitals, and midwifery practices. Pregnant women aged ≥18 years who had mastered the Dutch language were eligible to participate. Fear of childbirth was measured with the Wijma Delivery Expectancy Questionnaire online using a cut‐off score of ≥85 to indicate clinically relevant fear of childbirth. The primary outcome was the prevalence of fear of childbirth. We undertook additional analyses to specifically look at possible effect modification.ResultsIn total, 1102 pregnant women completed the questionnaire during the first wave of the pandemic, 731 during the second wave, and 364 before the pandemic. Fear of childbirth was present in 10.6%, 11.4%, and 18.4%, respectively. We considered possible effect modification, which indicated that age and parity had a significant influence. In participants during the first wave of COVID‐19, nulliparous women had significantly lower odds (odds ratio [OR] 0.50; 95% confidence interval [CI] 0.34–0.73; p < 0.01) of having a fear of childbirth than did the reference group. Both younger participants in the first wave (OR 0.59; 95% CI 0.37–0.93; p < 0.05) and older participants in the first wave (OR 0.44; 95% CI 0.28–0.71; p < 0.01) and the second wave (OR 0.36; 95% CI 0.21–0.62; p < 0.01) of COVID‐19 had lower odds of fear of childbirth than the reference group.ConclusionsPregnant women during the first and second waves of COVID‐19 had lower fear of childbirth scores than pregnant women before the pandemic, indicating less fear of childbirth during the pandemic. This could be explained by an increased level of information, more time to consume information, and better work–life balance with more people working at home during the pandemic.
