Factors affecting the nesting success of Swainson's Thrush (Catharus ustulatus) along an elevational gradient.

Montane birds experience a range of challenges that may limit their breeding success, including nest predation and severe climactic conditions. The continuing effects of climate change are causing shifts in biotic and abiotic factors that may compound these threats to montane bird species. In northeastern montane forests, many bird species are shifting downslope, potentially as the result of increased precipitation and temperature at higher elevations. Although lower elevations might be more favorable in terms of climactic conditions, nest predation is higher at lower elevations. Thus, montane birds might be faced with the opposing pressures of adverse climactic conditions at higher elevations and increased predation at lower elevations. We monitored nests of Swainson's Thrush (Catharus ustulatus) along an elevation gradient in the White Mountain National Forest in New Hampshire in 2016, 2018, 2019, and 2021 to examine the effect of biotic and abiotic factors on daily nest survival rate (DSR). Linear time explained the most variation of DSR in AICc model comparison, indicating that DSR decreases across the breeding season. Rain intensity (mm/h) had a weak negative effect on DSR, indicating that heavier rain per hour decreases Swainson's Thrush DSR. Moreover, we found some support for a negative interaction effect of elevation in conjunction with minimum daily temperature: DSR of Swainson's Thrush nests at low elevations (281 m) increased with increasing minimum daily temperatures and decreased at high elevations with increasing minimum daily temperatures. Our results suggest nesting survival of montane breeding birds may be at risk as heavier precipitation events become more frequent and intense due to the changing climate and raises the possibility that other passerine species could be at risk in this system.

Связь социального доверия и беспокойства о будущем в сравнительной кросс-культурной перспективе

<p style="text-align: justify;"><strong>Objective. </strong>Analysis of the effect of social trust on anxiety regarding the occurrence of various negative circumstances in the future.<br><strong>Background. </strong>Experiences of instability and uncertainty prompt us to reconsider the role of social trust.

Higher intraocular pressure is associated with slower axial growth in children with non-pathological high myopia

ObjectivesTo investigate the association between intraocular pressure (IOP) and axial elongation rate in highly myopic children from the ZOC-BHVI High Myopia Cohort Study.Methods162 eyes of 81 healthy children (baseline spherical equivalent: −6.25 D to −15.50 D) aged 7–12 years with non-pathological high myopia were studied over five biennial visits. The mean (SD) follow-up duration was 5.2 (3.3) years. A linear mixed-effects model (LMM) was used to assess the association between IOP (at time point t−1) and axial elongation rate (annual rate of change in AL from t−1 to t), controlling for a pre-defined set of covariates including sex, age, central corneal thickness, anterior chamber depth and lens thickness (at t−1). LMM was also used to assess the contemporaneous association between IOP and axial length (AL) at t, controlling for the same set of covariates (at t) as before.ResultsHigher IOP was associated with slower axial growth (β = −0.01, 95% CI −0.02 to −0.005, p = 0.001). There was a positive contemporaneous association between IOP and AL (β = 0.03, 95% CI 0.01–0.05, p = 0.004), but this association became progressively less positive with increasing age, as indicated by a negative interaction effect between IOP and age on AL (β = −0.01, 95% CI −0.01 to −0.003, p = 0.001).ConclusionsHigher IOP is associated with slower rather than faster axial growth in children with non-pathological high myopia, an association plausibly confounded by the increased influence of ocular compliance on IOP.

Interaction between beech and spruce trees in temperate forests affects water use, root water uptake pattern and canopy structure.

Beneficial and negative effects of species interactions can strongly influence water fluxes in forest ecosystems. However, little is known about how trees dynamically adjust their water use when growing with interspecific neighbours. Therefore, we investigated the interaction effects between Fagus sylvatica (European beech) and Picea abies (Norway spruce) on water-use strategies and aboveground structural characteristics. We used continuous in situ isotope spectroscopy of xylem and soil water to investigate source water dynamics and root water uptake depths. Picea abies exhibited a reduced sun-exposed crown area in equally mixed compared with spruce-dominated sites, which was further correlated to a reduction in sap flow of -14.5±8.2%. Contrarily, F. sylvatica trees showed +13.3±33.3% higher water fluxes in equally mixed compared with beech-dominated forest sites. Although a significantly higher crown interference by neighbouring trees was observed, no correlation of water fluxes and crown structure was found. High time-resolved xylem δ2H values showed a large plasticity of tree water use (-74.1 to -28.5‰), reflecting the δ2H dynamics of soil and especially precipitation water sources. Fagus sylvatica in equally mixed sites shifted water uptake to deeper soil layers, while uptake of fresh precipitation was faster in beech-dominated sites. Our continuous in situ water stable isotope measurements traced root water uptake dynamics at unprecedented temporal resolution, indicating highly dynamic use of water sources in response to precipitation and to neighbouring species competition. Understanding this plasticity may be highly relevant in the context of increasing water scarcity and precipitation variability under climate change.

The effects of causal and self-efficacy beliefs on help-seeking for people with depressive complaints: a quasi-experimental online study

BackgroundOnly approximately a third of people with depressive symptoms seek professional health care. Furthermore, people labelled as mentally ill may experience stigmatisation, which can impede help-seeking behaviour.AimTo examine the effects of three vignette-based interventions endorsing biopsychosocial causal beliefs and strengthening self-efficacy on help-seeking intention and behaviour, as well as the predictive values of these variables and previous treatment experience.MethodA quasi-experimental online study utilising a fractioned factorial design was carried out. People were screened for depressive symptoms and their current treatment status. After baseline assessment, they were randomly allocated into one of 24 groups receiving a combination of interventional messages. Actual help-seeking behaviour was measured at follow-ups 3 and 6 months after baseline.ResultsAltogether, N = 1,368 participants were included in the final analyses and N = 983 provided data on their help-seeking behaviour within 3 to 6 months after the baseline assessment. The intention to seek help from a general practitioner or a mental health professional was significantly influenced by the interventions. However, help-seeking behaviour was not influenced by the interventions. On a conceptual level, biopsychosocial causal beliefs (β = 0.09–0.23) and self-efficacy to seek help (β = 0.16–0.25) predicted help-seeking intention. There was a negative interaction effect of both self-efficacy beliefs on intention and behaviour, which changed depending on depression severity. In all models, the intention was the main predictor of actual behaviour. Treatment experience predicted both help-seeking intention and behaviour.ConclusionBiopsychosocial causal beliefs and self-efficacy have a direct effect on help-seeking intention. Interventions should include information on how to actually seek help as a means to strengthen self-efficacy beliefs and simulate previous treatment experience. Further research is needed to investigate the respective interaction effects on intention and behaviour.Clinical Trial Registrationhttps://drks.de/search/de/trial/DRKS00023557, German Clinical Trials Register: DRKS00023557.

Application of modified β-glucan/montmorillonite- based sodium alginate microsphere adsorbents for removing deoxynivalenol and zearalenone from corn steep liquor

Removing mycotoxins from by-products of corn wet-milling processing presents a critical challenge facing the grain industry. Corn steep liquor (CSL) is rich in protein and other nutrients. However, CSL is usually contaminated by mycotoxins, including deoxynivalenol (DON) and zearalenone (ZEN), which can be removed using suitable adsorbents. In this study, the efficiency of modified sodium alginate (SA)/β-glucan/montmorillonite (Mt) (SA/β-glucan/Mt) microsphere adsorbents in moving DON and ZEN from CSL was investigated. For this, the modified SA/β-glucan/Mt microspheres were analyzed using a scanning electron microscope (SEM) and Fourier-transform infrared spectroscopy (FTIR). The adsorption of microspheres was characterized by physical adsorption and hydrogen bonding analyses. The optimal adsorption conditions (i.e., incubation time, temperature, and dose) of the microspheres were investigated in spiked aqueous solution. An incubation time of 5 min, a temperature of 20 °C, and a ratio of 1:5 wt per volume (w/v) were determined to be the optimum conditions (1 μg/mL of DON and 20 μg/L of ZEN). Subsequently, the microspheres were applied to CSL and showed high adsorption capacity for DON and ZEN. The adsorption rates of mono- and multi-mycotoxin in spiked aqueous solutions using microsphere adsorbents were studied, and a negative interaction effect was observed between DON and ZEN in the CSL system. Moreover, simple and rapid regeneration of the microspheres was achieved, and the removal efficiency of mycotoxin from CSL was almost unaffected. Thus, the low-cost and highly regenerable modified SA/β-glucan/Mt microspheres can be employed as an effective adsorbent for removing both DON and ZEN from CSL.

Ancestry-attenuated effects of socioeconomic deprivation on type 2 diabetes disparities in the All of Us cohort

BackgroundDiabetes is a common disease with a major burden on morbidity, mortality, and productivity. Type 2 diabetes (T2D) accounts for roughly 90% of all diabetes cases in the USA and has a greater observed prevalence among those who identify as Black or Hispanic.MethodsThis study aimed to assess T2D racial and ethnic disparities using the All of Us Research Program data and to measure associations between genetic ancestry (GA), socioeconomic deprivation, and T2D. We used the All of Us Researcher Workbench to analyze T2D prevalence and model its associations with GA, individual-level (iSDI), and zip code-based (zSDI) socioeconomic deprivation indices among participant self-identified race and ethnicity (SIRE) groups.ResultsThe study cohort of 86,488 participants from the four largest SIRE groups in All of Us: Asian (n = 2311), Black (n = 16,282), Hispanic (n = 16,966), and White (n = 50,292). SIRE groups show characteristic genetic ancestry patterns, consistent with their diverse origins, together with a continuum of ancestry fractions within and between groups. The Black and Hispanic groups show the highest levels of socioeconomic deprivation, followed by the Asian and White groups. Black participants show the highest age- and sex-adjusted T2D prevalence (21.9%), followed by the Hispanic (19.9%), Asian (15.1%), and White (14.8%) groups. Minority SIRE groups and socioeconomic deprivation, both iSDI and zSDI, are positively associated with T2D, when the entire cohort is analyzed together. However, SIRE and GA both show negative interaction effects with iSDI and zSDI on T2D. Higher levels of iSDI and zSDI are negatively associated with T2D in the Black and Hispanic groups, and higher levels of iSDI and zSDI are negatively associated with T2D at high levels of African and Native American ancestry.ConclusionsSocioeconomic deprivation is associated with a higher prevalence of T2D in Black and Hispanic minority groups, compared to the majority White group. Nonetheless, socioeconomic deprivation is associated with reduced T2D risk within the Black and Hispanic groups. These results are paradoxical and have not been reported elsewhere, with possible explanations related to the nature of the All of Us data along with SIRE group differences in access to healthcare, diet, and lifestyle.

Personal Backgrounds, Constituency Demands and Policy Issues Raised by Deputies of China's National People's Congress

Abstract: Research on China's legislators has seldom explained the types of policy issues raised by legislators and has rarely demonstrated the influence of constituencies. This article reveals that National People's Congress deputies whose personal backgrounds are closely associated with specific types of policy issues or whose constituencies have stronger demands regarding these issues usually submit more proposals pertaining to the issues. Furthermore, negative interactive effects exist between deputies' personal backgrounds as farmers or members of ethnic minorities and constituency demands corresponding to rural or ethnic minority issues on the relevant proposals that they raise. These findings further indicate how information is transmitted by China's legislators without a strong electoral connection.

An Analysis of the Influence of Pan-Entertainment Trend of Social Development on Mass Media

With the development of society and people's increasing dependence on entertainment methods, mass media has gradually moved towards marketization. Influenced by various factors such as market driving, mass media pan-entertainment has gradually emerged and become increasingly popular and an irresistible trend. This trend is closely related to the era background and reasons for the emergence of mass media pan-entertainment. With its vivid image and great influence, mass media plays a vital role in contemporary society and people's daily lives. Based on available data, this study will comprehensively analyze the various manifestations of pan entertainment on new and traditional media, and explore the positive and negative multi-level interactive effects of mass media pan entertainment on humans, times, and social development. Research has found that in this internet age, some media have a tendency towards excessive entertainment and neglect humanistic sentiments. The negative impact of these media is worth pondering and reflecting on. Finally, the research summarizes and proposes development suggestions and directions to reduce the negative impact of mass media pan-entertainment and effectively play its positive role, hoping to provide an effective reference for relevant professional researchers and media industry workers.

Longitudinal relationship between child maltreatment, bullying victimization, depression, and nonsuicidal self-injury among left-behind children in China: 2-year follow-up.

Left-behind childre (LBC) in China are deeply concerned by society because of their high risk of emotional and behavioral problems. Depression and nonsuicidal self-injury are the most harmful and worrying negative emotional and behavioral problems in LBC. Unfortunately, LBCs are in unfavorable environments for a long time and are prone to negative interpersonal interactions. Child maltreatment and bullying victimization, as the two most typical negative interpersonal interactions in family and school environments, maybe the key risk factors for depression and nonsuicidal self-injury among LBCs. However, we are less known of the longitudinal effects of child maltreatment and bullying victimization on LBC's depression and nonsuicidal self-injury and their underlying mechanisms. This study used a two-year longitudinal design with three-time points to investigate the longitudinal effects of child maltreatment and bullying victimization on depression, nonsuicidal self-injury, and the mediating role of negative thoughts and self-compassion. A sample of 592 LBC (390 were males, Mage at time 1 = 9.56, SDage = 0.65; 202 were females, Mage at time 1 = 9.43, SDage = 0.63) completed a set of questionnaires at three-time points. This study used SPSS software (version 25.0) and MPLUS software (version 8.3) for all analyses. (1) Child maltreatment not only affects depression and nonsuicidal self-injury but also affects depression and nonsuicidal self-injury through negative thoughts. Child maltreatment affects depression through self-compassion and does not affect nonsuicidal self-injury. (2) Bullying victimization affects depression and nonsuicidal self-injury through negative thoughts and bullying victimization further affects depression through self-compassion but does not affect nonsuicidal self-injury. This study revealed the effects of negative interpersonal interactions (child maltreatment, bullying victimization) on LBC's adverse emotions and behaviors, and their underlying mechanisms, which helps to provide parents, schools, and psychoeducational workers with a new perspective on intervention.

Residential greenness alleviated the adverse associations of long-term exposure to ambient PM1 with cardiac conduction abnormalities in rural adults

Ambient air pollution was linked to elevated risks of adverse cardiovascular events, and alterations in electrophysiological properties of the heart might be potential pathways. However, there is still lacking research exploring the associations between PM1 exposure and cardiac conduction parameters. Additionally, the interactive effects of PM1 and residential greenness on cardiac conduction parameters in resource-limited areas remain unknown. A total of 27483 individuals were enrolled from Henan Rural Cohort study. Cardiac conduction parameters were tested by 12-lead electrocardiograms. Concentrations of PM1 were predicted by satellite-based spatiotemporal models. Levels of residential greenness were assessed using Enhanced Vegetation Index (EVI) and Normalized difference vegetation index (NDVI). Logistic regression models and restricted cubic splines were fitted to explore the associations of PM1 and residential greenness exposure with cardiac conduction abnormalities risk, interaction plot method was performed to visualize their interaction effects. The 3-year median concentration of PM1 was 56.47 (2.55) μg/m3, the adjusted odds rate (ORs) and 95% confidence intervals (CIs) for abnormal HR, PR, QRS, and QTc interval risk in response to 1 μg/m3 increase in PM1 were 1.064 (1.044, 1.085), 1.037 (1.002, 1.074), 1.061 (1.044, 1.077) and 1.046 (1.028, 1.065), respectively. Participants exposure to higher levels of PM1 had increased risks of abnormal HR (OR = 1.221, 95%CI: 1.144, 1.303), PR (OR = 1.061, 95%CI: 0.940, 1.196), QRS (OR = 1.225, 95%CI: 1.161, 1.294) and QTc interval (OR = 1.193, 95%CI: 1.121, 1.271) compared with lower levels of PM1. Negative interactive effects of exposure to PM1 and residential greenness on abnormal HR, QRS, and QTc intervals were observed (Pfor interaction < 0.05). Long-term PM1 exposure was associated with elevated cardiac conduction abnormalities risks, and this adverse association might be mitigated by residential greenness to some extent. These findings emphasize that controlling PM1 pollution and increasing greenness levels might be effective strategies to reduce cardiovascular disease burdens in resource-limited areas.

The doctor knows or the evidence shows: An online survey experiment testing the effects of source trust, pro-vaccine evidence, and dual-processing in expert messages recommending child COVID-19 vaccination to parents.

Increasing child vaccination rates is a critical step toward mitigating the spread of COVID-19. Both distrust in expert sources and concern about the safety and efficacy of vaccines may contribute to parent vaccine hesitancy. The present study is the first to test the effectiveness of building trust and providing evidence supporting child COVID-19 vaccines in recommendation messages for parents. Based on dual-processing theories, emphasis on source trustworthiness and pro-vaccine evidence may each be particularly effective when the other is not present. It was hypothesized that these two approaches would have main and interaction effects on perceived message effectiveness and pro-vaccine beliefs. A between-subjects 2 (trust-building appeal vs. no trust-building appeal) X 2 (pro-vaccine evidence vs. no pro-vaccine evidence) online survey experiment was conducted in December 2021 and January 2022 with United States parents/guardians of children <18 years old (n = 401). As hypothesized, trust and pro-vaccine evidence each had significant simple main effects on both outcomes. Analysis of variance showed a significant negative interaction effect of trust and pro-vaccine evidence on perceived message effectiveness [F(3, 394) = 6.47; η2 = 0.02, p = 0.002; 95% CI (0.01, 0.11)], supporting the dual-processing hypothesis. The interaction effect on pro-vaccine beliefs was also negative but not significant [F(3, 394) = 2.69; η2 = 0.01; p = 0.102; 95% CI (0.00, 0.03)]. Either highlighting evidence supporting vaccines or building trust in expert sources can influence parent vaccine support. Messages which include strong evidence supporting recommended behaviors may influence recommendation acceptance even among those with lower trust in expert sources and establishing trust may reduce the need to describe available evidence.

Dynamic Threshold Effect of Financial Development on the Country Risks–Subsidies–Firm Performance Nexus: Evidence from Chinese Renewable Energy Firms

ABSTRACT Using multifaceted financial development indicators and a dynamic panel threshold model, this study finds that different regimes of financial development have different effects on Chinese renewable energy firm performance through the interactive channel of country risks and subsidies. A high level of composite financial development strengthens the positive interaction effect between composite risk and subsidies on renewable energy firm performance, and a high level of banking sector development and stock market development, respectively, weakens and strengthens the negative interaction effect between composite risk and subsidies on renewable energy firm performance. Further, these threshold effects of financial development on renewable energy firm performance are also different when using economic, political, and financial risk indicators, and they also change with different ownership attributes. Thus, the Chinese government needs to improve the level of composite financial development and create a stable composite risk environment to achieve fully the potential of subsidies in promoting renewable energy firm performance.

Does organisational politics moderates the relationship between organisational culture and employee efficiency?

PurposeThe study aims to examine the relationship between organisational culture and employee efficiency and how organisational politics strengthens or weakens that relationship in the public sector of Ghana due to the perceived inefficiency of public sector employees.Design/methodology/approachThe study employs cross-sectional survey design and quantitative approach to collect the data from public sector employees in Ghana. The analysis is done using descriptive statistics, correlation and hierarchical regression models.FindingsThe results show that negative organisational politics is the predominant perceived politics in the Ghanaian public sector. Further, organisational culture and employee efficiency have significant positive association and organisational politics (positive and negative) significantly moderate the association. However, negative organisational politics depicts negative interaction effect, meaning that negative organisational politics affects the positive influence of organisational culture on employee efficiency.Practical implicationsThe findings imply that strategies such as formulation of organisational policy and strict enforcement of same to eradicate or minimise the practise of negative organisational politics, whilst positive organisational politics is encourages and awarded to induce employees to be efficient. This will enhance the overall effect of organisational culture on employee efficiency.Originality/valueThe study contributes significantly to extant literature by providing empirical evidence that organisational politics (positive and negative) effectively strengthens the association between organisational culture and employee efficiency from a developing country perspective.

The Role of ACEs and Discrimination on Mental Health: A Longitudinal Analysis Among College Students

ABSTRACT Both adverse childhood experiences (ACEs) and perceived discrimination have been found to impact mental health in adults, but less is understood about the ways they interact to affect anxiety and depression symptoms. In the spring and summer of 2020, there were large societal changes stemming from the COVID-19 pandemic and social and racial justice movements in the United States. The current study aimed to characterize the interactive associations of ACE history and perceived discrimination with mental health in a sample of college students assessed prior to the pandemic in the fall of 2019 and then again in the fall of 2020. Results showed that in 2019, greater discrimination and more ACEs were associated with greater anxiety/depression symptoms. In 2020, a negative interactive effect of ACE history and discrimination on mental health was found, such that for individuals with low ACEs, greater discrimination was associated with significantly greater anxiety/depression symptoms. We also found that increases in perceived discrimination from 2019 to 2020 were significantly positively associated with increases in anxiety/depression symptoms over that same time period. The findings highlight the significant impacts that both ACEs history and perceived discrimination have on mental health and suggest that experiences of discrimination should be thought of as a critical, dynamic factor impacting college students’ mental health.

Analytical method to improve the decision-making criteria approach in managing digital social channels

This study explores the decision-making process involved in managing digital communities in the digital social channel ecosystem, specifically in the context of antagonistic digital communication and harmful content dissemination. The rise of digital communities in social media has changed the way people interact with each other, form communities, and participate in social activities. However, these interactions can also lead to conflicts, and the dissemination of harmful content can pose a risk to users' information security. This research proposes a method to mitigate these issues and optimize efficacy while minimizing potential hazards. The proposed method is based on the analysis of the information situation in the management of digital communities under conditions of complete uncertainty, antagonistic behaviour, and partial uncertainty. The study examines the decision-making process involved in antagonistic interaction among users of digital social channels. The methods proposed in this research were implemented to prevent the adverse consequences of community conflicts and the dissemination of potential risks to the security of users' information through prompt and efficacious decision-making. The proposed strategy optimizes efficacy through the implementation of the Wald criteria while minimizing potential hazards by adhering to the Savage criteria. Additionally, the Hurwitz criteria, which presents a balanced approach incorporating both the maximum and minimum criteria, was also employed. The methods were tested within the online community present on the social media platform, Facebook social networks, and the results demonstrate that the suggested technique improves the effectiveness and validity of managers' decisions in digital communities. The study also highlights the use of social networks and the virtual sphere as tools for hybrid warfare on the internet, which can be effective. Effective community management is necessary to mitigate the negative effects of online interactions, and the proposed method offers a valuable tool for managers to make informed decisions and prevent adverse consequences.

Incorporating straw into intensively farmed cropland soil can reduce N2O emission via inhibition of nitrification and denitrification pathways

Straw incorporation (SI) combined with N fertilizer has been shown to affect soil N2O emission and N-related functional microbes in agriculture. However, the responses of N2O emission, community structure of nitrifiers and denitrifiers and related microbial functional genes to straw management strategies in the winter wheat season in China remain unclear. Here, we conducted a two-season experiment in a winter wheat field in Ningjing County, northern China, to examine four treatments: no fertilizer with (N0S1) and without maize straw (N0S0); N fertilizer with (N1S1) and without maize straw (N1S0), and their effects on N2O emissions, soil chemical parameters, crop yield, as well as the dynamics of nitrifying and denitrifying microbial communities. We found that seasonal N2O emissions decreased by 7.1–11.1% (p < 0.05) in N1S1 as compared to N1S0, without significant difference between N0S1 and N0S0. In combination with N fertilization, SI increased the yield by 2.6–4.3%, altered the microbial community composition, increased Shannon and ACE indexes, and decreased the abundance of AOA (9.2%), AOB (32.2%; p < 0.05), nirS (35.2%; p < 0.05), nirK (21.6%; p < 0.05) and nosZ (19.2%). However, in the absence of N fertilizer, SI promoted the major genera of Nitrosavbrio (AOB), unclassifiied_Gammaproteobacteria, Rhodanobacter (nirS), Sinorhizobium (nirK), which strongly correlated positively with N2O emissions. Thereby, a negative interaction effect between SI and N fertilizer on AOB and nirS emphasized that SI could offset the increase of N2O emission caused by fertilization. Soil moisture and NO3− concentration were the major factors affecting N-related microbial community structure. Our study reveals that SI suppressed N2O emission significantly and simultaneously decreased the abundance of N-related functional genes and altered denitrifying bacterial community composition. We conclude that SI helps to enhance yield and alleviate fertilizer-induced environmental costs in intensively farmed fields in northern China.

Examining high-performance work practices in academia: role of administrative workload and support staff

PurposeThe study aims to explore the effectiveness of performance-oriented practices like high-performance work practices (HPWPs) in higher education (HE), given its explicit focus on performance these days.Design/methodology/approachThe study uses hierarchical linear modeling using statistical package for social sciences (SPSS 22.0) to test the hypotheses. An intertwined framework of the ability–motivation–opportunity (AMO) model and the job demand-resources (JD-R) model was proposed. The study considered strategic hiring, recognition and participatory decision-making as ability, motivation and opportunity-enhancing practices respectively. Further, the study addressed the impact of institutional level moderators, like administrative workload (AWL) and support staff (SS).FindingsThe findings based on the responses of 385 faculties and 443 students from 36 Indian institutes, indicated that HPWPs enhanced the education performance (EP) of HE institutes. Further, results revealed that both AWL and SS had differential effects on the relationship between HPWPs and EP. Contrary to authors’ expectations, SS showed a negative effect of the relationship between HPWPs and EP.Research limitations/implicationsThe increased AWL was debilitating the beneficial effects HPWPs. The negative interaction effect of SS sheds light on the hidden issues surrounding SS in HE institutes. Based on findings, the study offered important theoretical and practical implications.Originality/valueTo the best of authors’ knowledge, the impact of innovative human resource (HR) practices in academia remains relatively under-researched, and the current study is an attempt to fill this void.

The Effects of Expressing Empathy/Autonomy Support Using a COVID-19 Vaccination Chatbot: Experimental Study in a Sample of Belgian Adults.

Chatbots are increasingly used to support COVID-19 vaccination programs. Their persuasiveness may depend on the conversation-related context. This study aims to investigate the moderating role of the conversation quality and chatbot expertise cues in the effects of expressing empathy/autonomy support using COVID-19 vaccination chatbots. This experiment with 196 Dutch-speaking adults living in Belgium, who engaged in a conversation with a chatbot providing vaccination information, used a 2 (empathy/autonomy support expression: present vs absent) × 2 (chatbot expertise cues: expert endorser vs layperson endorser) between-subject design. Chatbot conversation quality was assessed through actual conversation logs. Perceived user autonomy (PUA), chatbot patronage intention (CPI), and vaccination intention shift (VIS) were measured after the conversation, coded from 1 to 5 (PUA, CPI) and from -5 to 5 (VIS). There was a negative interaction effect of chatbot empathy/autonomy support expression and conversation fallback (CF; the percentage of chatbot answers "I do not understand" in a conversation) on PUA (PROCESS macro, model 1, B=-3.358, SE 1.235, t186=2.718, P=.007). Specifically, empathy/autonomy support expression had a more negative effect on PUA when the CF was higher (conditional effect of empathy/autonomy support expression at the CF level of +1SD: B=-.405, SE 0.158, t186=2.564, P=.011; conditional effects nonsignificant for the mean level: B=-0.103, SE 0.113, t186=0.914, P=.36; conditional effects nonsignificant for the -1SD level: B=0.031, SE=0.123, t186=0.252, P=.80). Moreover, an indirect effect of empathy/autonomy support expression on CPI via PUA was more negative when CF was higher (PROCESS macro, model 7, 5000 bootstrap samples, moderated mediation index=-3.676, BootSE 1.614, 95% CI -6.697 to -0.102; conditional indirect effect at the CF level of +1SD: B=-0.443, BootSE 0.202, 95% CI -0.809 to -0.005; conditional indirect effects nonsignificant for the mean level: B=-0.113, BootSE 0.124, 95% CI -0.346 to 0.137; conditional indirect effects nonsignificant for the -1SD level: B=0.034, BootSE 0.132, 95% CI -0.224 to 0.305). Indirect effects of empathy/autonomy support expression on VIS via PUA were marginally more negative when CF was higher. No effects of chatbot expertise cues were found. The findings suggest that expressing empathy/autonomy support using a chatbot may harm its evaluation and persuasiveness when the chatbot fails to answer its users' questions. The paper adds to the literature on vaccination chatbots by exploring the conditional effects of chatbot empathy/autonomy support expression. The results will guide policy makers and chatbot developers dealing with vaccination promotion in designing the way chatbots express their empathy and support for user autonomy.

How inter-firm cooperation and conflicts in industrial clusters influence new product development performance? The role of firm innovation capability

Despite ongoing cooperation among firms in industrial clusters, inter-firm conflicts are also prevalent, and little research has explored how these factors impact new product development (NPD) performance. In this study, we examine the influence of inter-firm cooperation and conflicts (i.e., constructive and destructive) on NPD performance, and explore the mediating role of innovation capability (i.e., incremental and radical) and the joint interactive effects of cooperation and conflicts on innovation capability. Based on data collected from a multi-sourced sample of 181 industrial cluster firms, our results confirm that innovation capability mediates the relationship between cooperation/constructive conflict and NPD performance. Specifically, we find that cooperation and constructive conflict positively affect both types of innovation capability, while destructive conflict negatively affects incremental innovation capability. Moreover, we identify a negative interaction effect of cooperation and constructive conflict on radical innovation capability, and a positive interactive effect of cooperation and destructive conflict on incremental innovation capability. These findings contribute to the literature on industrial clusters and provide practical implications for firm managers and government officials interested in regional development through industrial clusters.
