Polycomb repression of Hox genes involves spatial feedback but not domain compaction or demixing
Authors: Murphy Sedona , Boettiger Alistair Nicol 
Published: October 2022

AbstractPolycomb group (PcG) proteins modulate higher-order genome folding and play a critical role in silencing transcription during development. It is commonly proposed that PcG dependent changes in genome folding, which compact chromatin, contribute directly to repression by blocking binding of activating complexes and demixing repressed targets from non-repressed chromatin. To test this model we utilized Optical Reconstruction of Chromatin Architecture (ORCA) to trace the 3-dimensional folding of theHoxagene cluster, a canonical Polycomb target, allowing us to analyze thousands of DNA traces in single cells. In cell types ranging from embryonic stem cells to brain tissue, we find that PcG-bound chromatin frequently explores decompact states and partial mixing with neighboring chromatin, while remaining uniformly repressed, challenging the repression-by-compaction model. Using polymer physics simulations, we show that the flexible ensembles we observe can be explained by dynamic contacts mediated by multivalent interactions that are too weak to induce phase separation. Instead, these transient contacts contribute to accurate propagation of the epigenetic state without ectopic spreading or gradual erosion. We propose that the distinctive 3D organization of Polycomb chromatin, reflects a mechanism of “spatial feedback” required for stable repression.
Investigating cooperative strategies in low-carbon public–private partnership projects through evolutionary game
Authors: Zhu Jianbo , Shi Qianqian , Zhang Ce , Yuan Jingfeng , Li Qiming , Wang Xiangyu 
Published: October 2022

PurposePromoting low-carbon in the construction industry is important for achieving the overall low-carbon goals. Public–private partnership is very popular in public infrastructure projects. However, different perceptions of low-carbon and behaviors of public and private sectors can hinder the realization of low-carbon in these projects. In order to analyze the willingness of each stakeholder to cooperate towards low-carbon goals, an evolutionary game model is constructed.Design/methodology/approachAn evolutionary game model that considers the opportunistic behavior of the participants is developed. The evolutionary stable strategies (ESSs) under different scenarios are examined, and the factors that influence the willingness to cooperate between the government and private investors are investigated.FindingsThe results illustrate that a well-designed system of profit distribution and subsidies can enhance collaboration. Excessive subsidies have negative impact on cooperation between the two sides, because these two sides can weaken income distribution and lead to the free-riding behavior of the government. Under the situation of two ESSs, there is also an optimal revenue distribution coefficient that maximizes the probability of cooperation. With the introduction of supervision and punishment mechanism, the opportunistic behavior of private investors is effectively constrained.Originality/valueAn evolutionary game model is developed to explore the cooperation between the public sector and the private sector in the field of low-carbon construction. Based on the analysis of the model, this paper summarizes the conditions and strategies that can enable the two sectors to cooperate.
A relational perspective of schizophrenia at work
Authors: Khalid Afaf , Syed Jawad 
Published: October 2022

PurposeDespite a plethora of research on diversity and inclusion, workplace-related issues pertaining to individuals with schizophrenia (SCZ) remain grossly underexplored. This paper seeks to develop a relational, multilevel perspective of issues and challenges faced by individuals with SCZ in the work and career.Design/methodology/approachThe research draws on the findings from in-depth, qualitative interviews with schizophrenic individuals, individuals’ family members, healthcare professionals and nongovernmental organization (NGO) representatives.FindingsThe findings highlight the interconnected nature of multilevel issues faced by schizophrenic individuals and indicate that at the societal level, social stigma, economic conditions and inadequate government policies are the key challenges faced by them. At the organizational level workplace support and job suitability and design affect individuals’ employment. At the individual level, self-stigma affects the employability in a negative way whereas personal motivation and resilience, family and social support and realization of illness are the facilitating factors.Originality/valueThe study adds to disability and diversity literature by developing a relational perspective that holistically captures the issues faced by schizophrenic individuals and suggests that the work and employment-related issues may be simultaneously addressed at multiple levels.
Making a positive (or negative) first impression with small talk
Authors: Wiener Hillary J.D. , Flaherty Karen E. , Wiener Joshua 
Published: October 2022

Purpose
This paper aims to show that whether new customers respond well or poorly to small talk at the beginning of a service encounter depends on their relationship orientation, i.e. how exchange or communally oriented they are. The authors provide service providers with tactics to identify first-time customers’ relationship orientation or set customers’ small talk expectations and thus help them use small talk more effectively.

Design/methodology/approach
The authors examine the effect of small talk and relationship orientation on customer intentions to use a service provider in three experiments and one cross-sectional survey. The scenario-based experiments show causality and the effect in online and in-person scenarios. The survey replicates the effect among current customers of a small business.

Findings
Communally oriented customers respond positively to small talk, but exchange-oriented customers respond negatively to it. Mediation analyses reveal this occurs because small talk differentially leads to initial feelings of rapport and impatience for people high (versus low) in relationship orientation.

Practical implications
Service providers should consider customers’ relationship orientation before starting a conversation with small talk. The authors find providers can identify exchange-oriented customers by their choice of meeting format (in-person v. video chat). Managers can also use marketing materials to attract customers with a specific relationship orientation or to set customer expectations for small talk in the interaction.

Originality/value
Prior research has largely shown benefits to small talk, but the authors show significant downsides for some customers and to the best of the authors’ knowledge are the first to show process evidence of why these drawbacks occur.
How resource-based state-owned enterprises manage collective labor relations: a comparative case study in China
Authors: Lu Jingfu , Wang Chuhong , Jiang Luan 
Published: October 2022

PurposeThis study explores labor relations management behaviors of administrators and Party organizations in resource-based state-owned enterprises (SOEs) in China based on social exchange theory and embeddedness theory. It builds up a process model for managing collective labor conflicts in resource-based SOEs in the Chinese context.Design/methodology/approachA comparative case study is conducted using two resource-based SOEs with similar backgrounds but differing in effectiveness of the management of collective labor conflicts. Data are collected from interviews, archival sources and a one-month participatory investigation.FindingsThe administrators and Party organizations of resource-based SOEs manage collective labor conflicts by means of human resource practices (HRPs) and Party organizations' boundary-spanning behaviors (PBSBs), respectively; foremen and unions perform a mediation role, especially under circumstances where administrators employ high-performance HRPs and PBSBs are closely integrated with the production process. The marketization of the “new danwei system” exerts a “provocation effect” but does not necessarily lead to collective labor conflicts. The root cause of conflicts lies in the inherent defects of specific HRPs and PBSBs, as well as the absence of the Simmelian tie in the social exchange interaction of actors.Originality/valueFirst, this study develops a new construct of PBSBs for enterprises' Party organizations and explores its underlying mechanisms, which enriches the range of actors studied in the context of Chinese labor relations; Second, the authors develop a new dimension called “exemplification” building on the existing three-dimensional structure of boundary-spanning behaviors, which expands boundary-spanning theory. Third, the findings that Simmelian tie structure could better maintain the stability of labor relationship in the mediation process of labor-capital conflict management enrich the social exchange theory from the perspective of structure. Finally, this study deepens the existing research on HRPs by proposing a new explanation for disputes.
Examining tour guide humor as a driver of tourists’ positive word of mouth: a comprehensive mediation model
Authors: Fu Tianyu , Li Shuhao , XU Jie , Liu Min , Chen Guofu 
Published: October 2022

Purpose
Tour guides often use humor to entertain tourists, but the process of tour guide humor (TGH) affecting tourists’ positive word of mouth (PWOM) remains unclear. To fill the gap, this study aims to investigate how TGH enhances tourists’ PWOM through perceived relationship investment, perceived wellness value and trust in tour guides.

Design/methodology/approach
A comprehensive mediation model was proposed based on social exchange theory (SET). Data were obtained from 335 tour group tourists and analyzed using structural equation modeling.

Findings
Results present that TGH positively predicts tourists’ PWOM. Perceived relationship investment, perceived wellness value and trust in tour guides not only play mediating roles between TGH and tourists’ PWOM, respectively, but also jointly provide two sequential mediation paths (TGH → perceived relationship investment → trust in tour guides → tourists’ PWOM and TGH → perceived wellness value → trust in tour guides → tourists’ PWOM).

Research limitations/implications
The findings have practical value for tour guides and travel agencies to use TGH to improve tourists’ PWOM.

Originality/value
The major contribution is that a reciprocity-based framework rooted in SET was proposed to parse the complex process of TGH promoting tourists’ PWOM. Furthermore, this study enriches current knowledge by confirming that perceived wellness value is not only available in wellness tourism but can be experienced from TGH in mass tourism.

Published: October 2022

PurposeConsidering the last-mile delivery service supply chain as a social-ecological system rather than just a firm-based service system, this research exploit the COVID-19 pandemic disruption to investigate how the supply chain develops resilience from a viewpoint that integrates a social-ecological perspective with the traditional engineering one.Design/methodology/approachThis research adopt a multi-case study approach using qualitative data collected via semi-structured interviews with executive-level managers from nine leading UK last-mile delivery companies. Data analysis is guided by a research framework which is developed by combining the social-ecological perspective with the structure–conduct–performance paradigm. This framework aids the investigation of the impacts of external challenges on companies' resilience strategies and practices, as well as performance, in response to disruptions.FindingsThe research identifies three distinct pathways to resilience development: stabilization, focussing on bouncing back to the original normal; adaptation, involving evolutionary changes to a new normal; transformation, involving revolutionary changes in pursuit of a new normal-plus. Three strategic orientations are identified as operating across these pathways: people orientation, digital orientation, and learning orientation.Originality/valueIn contrast to the manufacturing supply chain focus of most current research, this research concentrates on the service supply chain, investigating its resilience with a social-ecological perspective alongside the traditional engineering one.
Predictions on usefulness and popularity of online reviews: evidence from mobile phones for older adults
Authors: Shou Minghuan , Bao Xueqi , Yu Jie 
Published: October 2022

PurposeOnline reviews are regarded as a source of information for decision-making because of the abundance and ready availability of information. Whereas, the sheer volume of online reviews makes it hard for consumers, especially the older adults who perceive more difficulties in reading reviews and obtaining information compared to younger adults, to locate the useful ones. The main objective of this study is to propose an effective method to locate valuable reviews of mobile phones for older adults. Besides, the authors also want to explore what characteristics of the technology older adults prefer. This will benefit both e-retailers and e-commerce platforms.Design/methodology/approachAfter collecting online reviews related to mobile phones designed for older adults from a popular Chinese e-commerce platform (JD Mall), topic modeling, term frequency-inverse document frequency (TF-IDF), and linguistic inquiry and word count (LIWC) methods were applied to extract latent topics and uncover potential dimensions that consumers frequently referred to in their reviews. According to consumers' attitudes towards different popular topics, seven machine learning models were employed to predict the usefulness and popularity of online reviews due to their excellent performance in prediction. To improve the performance, a weighted model based on the two best-performing models was built and evaluated.FindingsBased on the TF-IDF, topic modeling, and LIWC methods, the authors find that older adults are more interested in the exterior, sound, and communication functions of mobile phones. Besides, the weighted model (Random Forest: Decision Tree = 2:1) is the best model for predicting the online review popularity, while random forest performs best in predicting the perceived usefulness of online reviews.Practical implicationsThis study’s findings can help e-commerce platforms and merchants identify the needs of the targeted consumers, predict reviews that will get more attention, and provide some early responses to some questions.Originality/valueThe results propose that older adults pay more attention to the mobile phones' exterior, sound, and communication function, guiding future research. Besides, this paper also enriches the current studies related to making predictions based on the information contained in the online reviews.
Value co-creation through branded apps: enhancing perceived quality and brand loyalty
Authors: Tran Trang , Taylor David G. , Wen Chao 
Published: October 2022

PurposeBranded applications (apps) are increasingly important in marketers' omnichannel strategies. They have not only changed the way customers purchase but also changed the way how companies interact with customers. Building on value co-creation literature, this research investigates consumer brand engagement's role in enhancing perceived quality and brand loyalty via value co-creation.Design/methodology/approachUsing online survey data from 355 brand app users, a conceptual model is tested employing the partial least squares structural equation modeling.FindingsThe results suggest that not only does branded app personalization drives brand co-creation (fully mediated by consumer brand engagement) but that this process also increases perceived quality and brand loyalty among users of branded apps.Research limitations/implicationsData for the study are self-reported and thus may not accurately reflect actual attitudes and behaviors. In addition, respondents were students within the United States who, although representative of branded app users, may limit the generalizability of the study.Practical implicationsKnowing that branded apps can influence customers' perception of the quality and value of their apps, products and services, or even their associated brands, marketers and app designers should work together to provide a value co-creation platform through the apps to increase customers' personalized, engaging experience.Originality/valueAlthough various relationships between personalization, engagement and co-creation have been studied, along with their impact on loyalty and perceived value, the interaction between these factors is not widely understood. The study examines these interactions in the context of branded apps, through the service-dominant logic perspective.
Effects of elevated CO2 and warming on the root‐associated microbiota in an agricultural ecosystem

Published: October 2022

AbstractPlant root‐associated microbial communities profoundly affect plant nutrition and productivity. Although elevated atmospheric CO2 and warming affect above‐ and belowground plant processes, it remains unclear how root‐associated microbial communities respond to elevated CO2 and warming. In this study, an open‐air field experiment was conducted to assay the interactive effects of elevated CO2 (500 ppm) and warming (+2°C) on the root‐associated microbiota and soil enzyme activities in a rice–wheat rotation ecosystem. The results revealed that elevated CO2 significantly increased rhizosphere soil organic carbon (SOC) and total nitrogen contents. In addition, glucosidase, β‐xylosidase, and phosphatase activities significantly increased. The richness and Shannon diversity indices were significantly higher in rhizosphere soil than in root endosphere. Elevated CO2 and warming significantly impacted the rhizosphere soil microbiota and altered their composition by changing the relative abundance of some specific groups. Soil pH, SOC, and available potassium content significantly altered the dominant bacterial phyla in the rhizosphere. SOC affected root endophytic bacterial phyla. Bacterial and fungal genera were significantly correlated with soil variables in the rhizosphere than in the root endosphere. These results indicate that microbial communities in the rhizosphere are more sensitive to elevated CO2 and warming than those in the root endosphere.
Low Traffic Neighbourhoods and the Paradox of UK Government Control of the Active Travel Agenda
Authors: Dudley Geoffrey , Banister David , Schwanen Tim 
Published: October 2022

AbstractLow traffic neighbourhoods (LTNs) are designed to remove motorised traffic from residential streets, while leaving them permeable to pedestrians and cyclists, and they have become a popular means to promote active travel. During the recent pandemic, the government introduced the Active Travel Fund in England to facilitate the rapid implementation of LTNs, but this also resulted in a powerful top‐down control element. This in turn has resulted in a paradox where funding is contingent on certain conditions being met, but insufficient and changing guidance has been given to the local authorities charged with implementation. This article outlines this highly unpredictable process, the controversies and the uncertain implementation through the development of the LTN process in England and the experience of Oxford, where many of the issues are currently being confronted.
Struggling, helping and adapting: Crowdfunding motivations and outcomes during the early US COVID‐19 pandemic
Authors: Kenworthy Nora , Jung Jin‐Kyu , Hops Emily 
Published: October 2022

AbstractDuring the early months of COVID‐19, many people in the US turned to charitable crowdfunding to seek and provide assistance. Little is known about the needs, hopes or experiences that motivated US pandemic crowdfunding and how these were correlated with campaign success. This study uses a mixed‐methods data analysis of a randomised cluster sample of 919 US GoFundMe campaigns during the first 7 months of the pandemic. Overall, most campaigns performed poorly, and 38% got no donations at all. The largest proportion of campaigns aimed to address individual, acute financial struggles, often arising from considerable challenges accessing or qualifying for government assistance. These campaigns, as well as those involving campaigners and beneficiaries of colour, tended to be least successful. Qualitative thematic analysis revealed three key crowdfunding motivations that reflect individualistic, agentive responses to the pandemic: struggling, helping and adapting. These motivations reveal a shift away from social suffering and collective mobilisation and towards largely individualised efforts of survival as digital crowdfunding becomes a key domain of crisis response. Crowdfunding platforms are playing an increasingly important role in mediating and influencing individual and collective responses to crisis, which has important political ramifications for how societies perceive and address health emergencies.
Sweet Femininities: Women and the Confectionery Trade in Eighteenth‐Century Barcelona
Authors: Manzanares Mileo Marta 
Published: October 2022

AbstractThis article examines the intersections between sweetness, femininity and the confectionery trade in eighteenth‐century Barcelona, at a time of growing consumption of sugar and slavery. Drawing on a range of underexplored archival material, this study traces the stories of women of different social groups, namely, elite housewives, nuns and tradeswomen who engaged with the production and trade of sweets in ingenious ways. This article argues that in the period when women were culturally diminished through their portrayals as ‘sweet’ and barred by guild structures, many women exercised social and economic agency in the confectionery trade in Barcelona.
Impacts of a nutrient trading plan on stream water quality in Sugar Creek, Ohio
Authors: Miller Samuel A. , Lyon Steve W. , Moore Richard H. 
Published: October 2022

AbstractIn the early 2000s, a phosphorus nutrient trading plan (NTP) requiring best management practices (BMPs) to be installed as pollution abatement strategies to offset phosphorus waste from the Alpine Cheese Company was implemented in four subwatersheds of Sugar Creek in northeast Ohio. To assess the impacts of the Alpine NTP, 49 sites were sampled approximately biweekly from 2010 to 2018 for phosphate, total phosphorus, nitrate, ammonia, and total nitrogen. In addition, the Ohio Environmental Protection Agency conducted stream health surveys at 21 sites before and after the BMPs were implemented. This study evaluated the potential impact of 68 BMPs implemented under the NTP on the observed changes in nutrient concentrations and stream health indicators. Most nutrient concentrations observed during high discharge conditions showed significant declines from 2010 to 2018 for all subwatersheds, which was most likely due to BMPs that reduced erosion and surface runoff. However, there were fewer significant declines and some significant increases in nutrient levels during low discharge conditions, suggesting a possible contribution from legacy nutrient sources. Most sites reported increases in stream health indicators, but many streams are still below recommended levels. Collectively, the installation of BMPs and decreases in nutrient concentrations observed during high discharge conditions can be attributed to the NTP and likely contributed to improved stream health.
