Gig worker typology and research agenda: advancing research for frontline service providers
Authors: Davidson Alexander , Gleim Mark R. , Johnson Catherine M. , Stevens Jennifer L. 
Published: June 2023

PurposeThe unique employment status of gig workers as independent contractors and their impact on consumers provide an important opportunity for the current research to understand gig workers' perceptions of their employment and how that affects job performance outcomes. These gig workers serve as the frontline service providers for platforms like Airbnb hosts, Lyft drivers and Wag walkers performing customer-facing services. However, their status as gig workers, not traditional employees, presents challenges to platforms. The purpose of this research is to gain insights into the profiles of gig workers, examine the challenges platforms have in retaining high-performing workers and provide a research agenda on this important group of frontline service providers.Design/methodology/approachIncorporating variables deemed important in examining self-determination theory, a large-scale data collection via an online survey was administered, yielding 447 completed surveys. A two-step cluster analysis procedure was conducted to categorize sample respondents into four distinct groups.FindingsFour groups emerged from the cluster analysis, labeled “Ambivalent Outsider,” “Competent Cog,” “Independent Insider” and “Committed Comrade.” The results suggest that there are significant differences across all variables and groups based on gig worker responses and self-reported customer satisfaction scores. The gig worker profiles developed are then utilized to formulate research propositions that are the basis for the research agenda presented.Practical implicationsThe goal of many collaborative consumption platforms may be to hire Independent Insiders or Committed Comrades; however, that is difficult to attain with every hire. Thus, the segmentation results provide insights for companies seeking to hire, retain, and successfully motivate their workforce.Originality/valueGiven the freedom and flexibility afforded to gig workers, and the importance they have on the service experience for customers, understanding their own perceptions of employment and performance is critical to ensuring a positive experience for all parties. Research on collaborative consumption has largely focused on consumers or the management of freelance workers with only tangential applicability to gig work. This paper offers a comprehensive research agenda for gig worker management based on the typology of gig workers created.

PurposeThe outbreak of COVID-19 has become a major public health emergency worldwide. How to effectively guide public opinion and implement precise prevention and control is a hot topic in current research. Mining the spatiotemporal coupling between online public opinion and offline epidemics can provide decision support for the precise management and control of future emergencies.Design/methodology/approachThis study focuses on analyzing the spatiotemporal coupling relationship between public opinion and the epidemic. First, based on Weibo information and confirmed case information, a field framework is constructed using field theory. Second, SnowNLP is used for sentiment mining and LDA is utilized for topic extraction to analyze the topic evolution and the sentiment evolution of public opinion in each coupling stage. Finally, the spatial model is used to explore the coupling relationship between public opinion and the epidemic in space.FindingsThe findings show that there is a certain coupling between online public opinion sentiment and offline epidemics, with a significant coupling relationship in the time dimension, while there is no remarkable coupling relationship in space. In addition, the core topics of public concern are different at different coupling stages.Originality/valueThis study deeply explores the spatiotemporal coupling relationship between online public opinion and offline epidemics, adding a new research perspective to related research. The result can help the government and relevant departments understand the dynamic development of epidemic events and achieve precise control while mastering the dynamics of online public opinion.

Purpose
This paper aims to examine the prevalence and reasons for delayed discharge from two regional assessment and treatment units (ATUs) for people with learning disabilities, in line with the transforming care agenda.

Design/methodology/approach
This is a retrospective evaluation of 44 admissions and discharges from two ATUs from February 2019 to March 2022.

Findings
Of 44 admissions who were discharged during the included period, 20 experienced delays in their discharge. Delayed discharges occurred despite the two ATUs meeting standards for length of assessment and treatment as specified by the Learning Disability Professional Senate. The most prevalent reasons for discharge delays were identification of a new placement, recruitment of care staff and building work.

Originality/value
This paper offers an in-depth evaluation of recent delayed discharges from two regional ATUs, highlighting the most common reasons for delays and offering suggestion for reducing delays in future.

Nature-inspired awe toward tourists’ environmentally responsible behavior intention
Authors: Xu Songjun , Hu Yaou 
Published: June 2023

Purpose
Awe is an important yet largely overlooked emotion in tourism. This paper aims to reveal the underlying mechanism of the effects of nature-inspired awe on stimulating tourists' environmentally responsible behavior (TERB) intention by delving into the serial mediation effect of state construal level, small-self perception and state connectedness to nature (CNT).

Design/methodology/approach
This research was built upon the appraisal theory of emotion. Study 1 was a scenario-induced quasi-experimental study to test the proposed model linking awe, small-self perception, state CNT and TERB intention. A total of 271 valid questionnaires were collected via an online questionnaire platform. Study 2 was a field study designed to replicate the findings of Study 1 and further uncover the mediating role of the state construal level. Study 2 was conducted in Baiyun Mountain Scenic Area, China. A total of 229 valid questionnaires were used for analysis.

Findings
This research deepens our understanding of the effects of nature-inspired awe in the tourism and travel fields. This research uncovers the underlying mechanism by which awe increases TERB intention through serial mediation. Specifically, awe inspires tourists to apply a higher level of construal, which makes tourists perceive a smaller self, making them feel more connected to nature and exert more intention to adopt ERB.

Originality/value
This research linked tourists' mindset (i.e. state construal level), internal (i.e. small-self perception) and external (i.e. state CNT) cognition in an integrated model, explaining how nature-inspired awe contributes to eliciting TERB intention. The findings add critical theoretical contributions to the travel and tourism literature and provide important implications for the tourism industry to inspire awe and benefit from such emotion.

Abstract

The thermal sensitivity of early life stages can play a fundamental role in constraining species distributions. For egg‐laying ectotherms, cool temperatures often extend development time and exacerbate developmental energy cost. Despite these costs, egg laying is still observed at high latitudes and altitudes. How embryos overcome the developmental constraints posed by cool climates is crucial knowledge for explaining the persistence of oviparous species in such environments and for understanding thermal adaptation more broadly.

Here, we studied maternal investment and embryo energy use and allocation in wall lizards spanning altitudinal regions, as potential mechanisms that enable successful development to hatching in cool climates. Specifically, we compared population‐level differences in (1) investment from mothers (egg mass, embryo retention and thyroid yolk hormone concentration), (2) embryo energy expenditure during development, and (3) embryo energy allocation from yolk towards tissue.

We found evidence that energy expenditure was greater under cool compared with warm incubation temperatures. Females from relatively cool regions did not compensate for this energetic cost of development by producing larger eggs or increasing thyroid hormone concentration in yolk. Instead, embryos from the high‐altitude region used less energy to complete development, that is, they developed faster without a concomitant increase in metabolic rate, compared with those from the low‐altitude region. Embryos from high altitudes also allocated relatively more energy towards tissue production, hatching with lower residual yolk: tissue ratios than low‐altitude region embryos.

These results are consistent with local adaptation to cool climate and suggest that this is underpinned by mechanisms that regulate embryonic utilisation of yolk reserves and its allocation towards tissue, rather than shifts in maternal investment of yolk content or composition.
Towards a trait‐based framework for marine macroalgae: Using categorical data to explore the nature of emergent functional groups
Authors: Fong C. R. , Ryznar E. R. , Smith L. L. , Fong P. 
Published: June 2023

Abstract

While trait‐based approaches have been effectively leveraged by plant ecologists to advance our understanding of community responses to major global challenges, such as climate change and invasive species, the study of marine macroalgae is still mired in a functional group (FG) framework developed in the 1980s.

In this paper, we used predominantly categorical data for 18 macroalgal traits that were accessible in public databases and/or the literature to explore their usefulness in a trait‐based framework for marine macroalgae. Species were clustered into emergent, data‐driven groups using a Gower dissimilarity matrix, then a k‐medoid clustering approach called partitioning around the medoids.

We identified 14 emergent groups (EGs) that captured a spectrum of strategies used by different macroalgal species. However, significant ‘gaps’ in trait space may identify evolutionary constraints to algal adaptive strategies. Multivariate analysis showed how the 18 traits created trait space and drove the clustering. A spectrum of strategies and the influence of multiple traits imply that algal strategies are likely governed by complex multivariate, not bivariate, trade‐offs. Finally, we found that our EGs appeared to reflect multivariate trade‐offs and diverse ecological strategies more than the traditional FG model for macroalgae. We tested the usefulness of our EGs by comparing real‐world spatial distributions of species across habitats with known strong environmental filters to their area occupied in trait space. We found significant separation in trait space and divergent occupancy patterns across global distributions, attachment substrates and elevational zones. These results support the use of categorical data accessible in the literature as a useful step towards developing trait‐based ecology for marine macroalgae.

Synthesis. Our findings indicate that readily accessible categorical traits produce emergent FGs that reflect environmental filtering and therefore demonstrate the power of trait‐based approaches over the current FG framework. Furthermore, we posit that categorical traits are a valuable and potentially complementary addition to a newly developing database of continuous traits because they encompass a broader, more globally accessible set of traits.
Wildfires disturb the natural skin microbiota of terrestrial salamanders
Authors: Mulla Lubna , Hernández‐Gómez Obed 
Published: June 2023

AbstractEnvironmental change can disturb natural associations between wildlife and microbial symbionts, in many cases to the detriment of host health. We used a North American terrestrial salamander system to assess how the skin microbiota of amphibians responds to wildfires. In northern California's redwood/oak forests, we assessed how recent wildfires affected the skin microbiota of three different salamander species (Taricha sp., Batrachoseps attenuatus, and Ensatina eschscholtzii) over two different sampling seasons in 2018 and 2021. We found species‐specific responses to wildfire disturbance on the alpha diversity of the skin microbiota of terrestrial salamanders, although burning in general altered the composition of the skin microbiota. The effect of burning on alpha diversities and body condition indices varied by sampling season, suggesting an additional effect of annual climatic conditions on body condition and skin microbiota response. We tested all salamanders for Batrachochytrium dendrobatidis and found four infected individuals in 2018 and none in 2021. Our study documents correlations in the skin microbiota response to an increasing source of disturbance in western North American ecosystems. In addition, our results highlight the need to consider the effects of increased wildfire regimes/intensities and longitudinal effects on wildlife‐associated microbiota and animal health.

AbstractThe present level of academic achievement and functional performance (PLAAFP) is an essential component of the individualised educational program (IEP) process because it identifies student strengths and areas for growth. However, there is minimal research that examines components of an IEP and student outcomes. The current study examined the relationship between PLAAFP quality and student achievement, and between training and ongoing professional development and quality of the PLAAFP. The data were obtained from 211 special education teachers in one state. Results suggested that ongoing professional development predicted the quality of the PLAAFP statement, accounted for a large amount of the variance (r2 = 0.14) in the PLAAFP quality score, and was a stronger predictor than participating in a single training. Additionally, PLAAFP quality predicted winter achievement scores beyond the school district, fall achievement scores and teacher variables, and accounted for significant and moderate amount of unique variance for reading (r2 = 0.05) and math (r2 = 0.07). Implications for research and practice are included.

Published: June 2023

AbstractThe root‐knot nematode Meloidogyne incognita is one of the most damaging plant parasitic nematodes in the world. In this study, the effect of cystatin from Amaranthus hypochondriacus (AhCPI) as a potential control agent for M. incognita was explored. In vitro bioassays demonstrated that AhCPI affects the growth and development of eggs and the infectivity of juveniles (J2) of M. incognita, such as mortality and slower development, showing characteristic tissue damage. Mortality levels were quantified by Probit analysis, estimating LC50s of 1.4 mg/mL for eggs and 0.028 mg/mL for J2. In planta bioassays showed that infected tomato seedlings treated with 0.056 mg/mL of AhCPI showed a 60% reduction in the number of galls, as compared with untreated J2‐inoculated seedlings. Under greenhouse conditions, three applications of 10 mL of AhCPI (1.4 mg/mL) in the soil around the stem of M. incognita‐infected tomato plants, reduced the number of galls by 93 ± 8%, as compared to the control M. incognita‐infected plants. The application of AhCPI to the infected plants increased the yield (10.7%) of harvested tomato fruits, as compared to infected plants. These results show the potential of AhCPI for the control of M. incognita in tomato plants.

Authors: Graham David J. , McCarron Luke , Phillips Teresa , Sivakumar Brahman 
Published: June 2023

AbstractBackgroundAuslan is used by the Australian deaf community and relies heavily on hand, wrist, and elbow movement. Upper limb injury or dysfunction may require surgical intervention to alleviate pain and provide a stable skeleton for function, leading to partial or complete reduction in motion. The aim of this study was to assess the wrist, forearm, and elbow motion required to communicate via Auslan, to tailor optimal interventions in this population.MethodsA biomechanical analysis was conducted on two native Auslan communicators, who signed 28 pre‐selected and common Auslan words and phrases.ResultsSagittal plane wrist and elbow motion was found to be of greater importance than axial plane forearm rotation. Relative elbow flexion and generous wrist motion was common for many of the words and phrases, while end‐range elbow extension was not recorded.ConclusionThe maintenance of wrist and elbow motion should be prioritized when selecting surgical interventions for patients who communicate using Auslan.

Published: June 2023

AbstractThe health‐promoting behaviors of miners are of great significance to their physical and mental well‐being. With a focus on enhancing their overall health, this study aimed to explore the determinants and influencing mechanisms of health‐promoting behaviors in miners. Initially, the latent Dirichlet allocation (LDA) model was utilized to extract topical keywords from literature over the last 23 years and to categorize the determinants based on integrating the health promotion model and the health belief model. Subsequently, a meta‐analysis was performed based on 51 related empirical research to explore the mechanisms between determinants and health‐promoting behaviors. The results indicated that (1) the factors influencing miners' health‐promoting behaviors can be divided into four dimensions: physical environment, psychosocial environment, individual characteristics, and health beliefs. (2) Noise was negatively related to health‐promoting behaviors, while protective equipment, health culture, interpersonal relationships, health literacy, health attitudes, and income were positively related to health‐promoting behaviors. (3) Protective equipment and health literacy were positively related to perceived threat, whereas interpersonal relationships were positively related to perceived benefits. This study sheds light on the mechanisms influencing miners' health‐promoting behaviors and could inform behavioral interventions in occupational health.
Can I control my actions and emotions? Examining when and why employees react adaptively or maladaptively to coworker voice
Authors: Zhou Xiang , Chong SinHui , Tong Jiajin 
Published: June 2023

AbstractVoice highlights important issues in the workplace, but it may be malfunctional if recipients do not possess the adequate mastery to act on the feedback received. Our research draws on the control value theory of emotions to explain how appraisals and affective processes shape employees' adaptive or maladaptive responses to challenge‐oriented voices from their coworkers. We contend that constructive (destructive) coworker voice activates a positive (negative) affective state more strongly in recipients who perceive higher (vs. lower) behavioral control because they will attribute greater personal responsibility over the voice content. We also expect the affective states to predict interpersonal citizenship behavior and work withdrawal behavior more strongly in recipients with lower (vs. higher) emotional control due to their greater susceptibility to the influences of affective states. The results from three‐wave, multi‐source data collected from 307 insurance sales representatives support most of our hypotheses, except that perceived behavioral control does not moderate the link between destructive coworker voice and employee negative affective state. The findings extend voice literature by taking a recipient perspective on how and why they react differently to constructive or destructive coworker voice, and offer practical suggestions for facilitating optimal behavioral responses to coworker voice in an applied setting.
