Social network relationship, supply chain resilience and customer-oriented performance of small and medium enterprises in a developing economy
Authors: Asamoah David , Agyei-Owusu Benjamin , Ashun Elizabeth 
Published: April 2020

PurposeWhile the concept of supply chain resilience has received lots of scholarly and policy interest over the past few years, empirical research examining its sources and outcomes remains inadequate, particularly, in the context of small and medium enterprises (SMEs). Grounded in the resource-based view and social capital frameworks, the study examines the relationship between social network relationship, supply chain resilience and customer oriented performance.Design/methodology/approachThe study develops and empirically tests a research model that proposes social network relationships and customer-oriented performance as the antecedent and outcome respectively of supply chain resilience. Data was obtained from a survey of 110 SMEs in Ghana.FindingsThe findings of the study suggest that a firm's external and internal social networks can be leveraged to enhance its supply chain resilience and customer-oriented performance. Supply chain resilience was also found to enhance customer-oriented performance. Additionally, supply chain resilience was found to significantly mediate the effect of social network relationships on customer-oriented performance.Originality/valueThis is the first study that empirically explores and establishes the relationship between social network relationships, supply chain resilience and customer-oriented performance to the best of the authors’ knowledge.

Authors: Susanto Tantut , Rahmawati Iis , Wantiyah  
Published: April 2020

PurposeOccupational health promotion programmes targeting the Indonesian agricultural farmers (AFs) are limited. This action research aimed to involve the AFs in the research and development of community-based occupational health promotion (COHP) programme, which is tailored to meet their perceived needs for preventing health problems related to occupational workplace.Design/methodology/approachThis study employed the qualitative action research approach. The participants (n = 136) were farmers from seven regions in the rural areas of East Java, Indonesia. The COHP was examined from public health centres (PHCs) in seven regions through eight steps, including recognition, analyses, planning, communication, preparation, implementation, evaluation and continuity of programme, for eight weeks. Data were collected through focus group interviews and examined using qualitative content analysis.FindingsThe findings revealed that the participants not only lacked health status but were also required to promote a comprehensive programme for occupational health and safety. The health problems of AFs were identified as the lack of nutrition and high blood pressure, which are related to un-ergonomic condition during work, limited use of personal protective equipment, high stress and workload. The lack of support for AF groups to prevent health problems and to access health services was a key theme for all the participants. Therefore, self-help group as social support was designed to solve the health problems among AFs.Originality/valueThe COHP, through action research, provided a change strategy for AFs to manage and promote occupational health and safety within their practice. The study findings could be used in the development of a framework for PHCs in delivering occupational health and safety practices in the agricultural sectors.
Dining alone: improving the experience of solo restaurant goers
Authors: Brown Lorraine , Buhalis Dimitrios , Beer Sean 
Published: April 2020

Purpose
Solo travel for leisure and business is increasing. It is therefore timely to conduct research into the experiences of solo tourists. This paper aims to explore one aspect of the solo tourist experience that can be challenging, that of dining alone. This topic has received little attention in the tourism or hospitality literature.

Design/methodology/approach
A qualitative approach was adopted and narrative inquiry was selected as the optimum route to obtain detailed and rich accounts of the experiences of solo diners. In-depth interviews of 27 solo tourists were conducted with varying socio-demographic characteristics.

Findings
This study shows that though travelling alone is prized by participants, dining alone, especially in the evening, is often discomfiting. Discomfort is caused by the perceived negative judgement of others and is mitigated by the use of various props such as books and mobile phones.

Research limitations/implications
A research agenda is put forward on the aspects of the solo tourist/diner experience.

Practical implications
The paper concludes by asking what can be done to ameliorate the solo dining experience and provides some recommendations to hospitality operators to support this market and improve competitiveness and profitability. The paper shows that inclusive environments can attract multiple market segments and agile restaurants can develop both solo and plural dining experiences.

Originality/value
This paper addresses a topic that has received limited scholarly attention as well as industry engagement despite the growth in solo travel.
Product recall strategy in the supply chain: utility and culture
Authors: Schniederjans Dara , Khalajhedayati Mehrnaz 
Published: April 2020

PurposeProduct recalls have the potential to damage firm and consumer quality reputation. While globalization has brought about various economic benefits, expanding supply chain networks have also made it more difficult for downstream organizations to manage product recall strategy. This study aims to examine the role of culture on a manufacturer's initiation of a recall and the severity of the remedy chosen for the product recall.Design/methodology/approachUtilizing the culture-specific argument, this study uses an exploratory approach to assess how cultural variables impact recall strategy utilizing a large-scale data analysis with a cross-sectional time-series panel of 898 firms.FindingsThe results provide support for the expected utility hypothesis that the more severe the consequence, the more likely a manufacturer will decide to recall the product. Moreover, the more likely the manufacturer will provide greater returns to the consumer. However, these relationships are impacted to differing degrees by the manufacturer's cultural origin.Originality/valueThese results provide evidence to researchers about how culture impacts the expected utility hypothesis in the decision theory. The study examines how deeply embedded cultural variables impact the relationship between the foreseeable consequence of the product recall and the recall facilitator and remedy.
Perspective directions of state regulation of competition between human and artificial intellectual capital in Industry 4.0
Authors: Bogoviz Aleksei V. 
Published: April 2020

PurposeThe purpose of the research is to determine the perspective directions of state regulation of competition between human and artificial intellectual capital in Industry 4.0 and to develop scientific and methodological recommendations for their implementation. For this, the directions of state regulation of competition between human and artificial intellectual capital are described, monitoring of competition between human and artificial intellectual capital by the example of modern Russia (2019) is performed and scientific and practical recommendations for state regulation of competition between human and artificial intellectual capital are developed, with their approbation by the example of modern Russia (2019).Design/methodology/approachA method of expert evaluation is used for collection of the information and empirical data. The method of comparative analysis is used for comparing the successfulness of implementing the distinguished directions of state regulation of competition between human and artificial intellectual capital (4.1) according to the official statistics to their current evaluation according to the interested parties. Also, future evaluation (forecasts) according to the interested parties (until 2045) is determined.FindingsIt is substantiated that during evaluation of state regulation of competition between human and artificial intellectual capital in Industry 4.0, one cannot use only the official statistics, as these data are fragmentary and indirect. Fuller and more precise data are provided by assessment according to the interested parties. They allow determining the current and the future state of affairs and, based on it, compiling a forecast and developing a long-term strategy of state regulation of competition between human and artificial intellectual capital in Industry 4.0.Originality/valueThe perspective directions of state regulation of competition between human and artificial intellectual capital in Industry 4.0 are as follows: stimulation of competition in the market of intellectual capital, social risk management of the market of intellectual capital, managing international competition in the market of intellectual capital and ecological risk management of the intellectual capital market. As the experience of modern Russia shows, even at the initial stage of transition to Industry 4.0, the measures of state regulation of competition between human and artificial intellectual capital are not enough, but their deficit is moderate. In the course of development of Industry 4.0, the necessity for the measures of regulation will grow, and their deficit will increase. That's why there's a need for strategic approach to their implementation, which envisages their systemic reconsideration and supplementing. An author's algorithm is offered for this.
Affectivity and riskiness of retirement investment decisions
Authors: Palmer Joshua C. , Chung Yunhyung , Park Youngkyun , Wang Gang 
Published: April 2020

PurposeDrawing on broaden-and-build theory and promotion- and prevention-focus theory, the authors examined the role of positive and negative affectivity (PANA) on the riskiness of investment decisions. The authors also examined the mediating impact of financial knowledge network intensity (i.e. the level of communication with financially literate others in employees' social network) on the PANA—riskiness of investment decisions relationship.Design/methodology/approachStudy 1 used a sample of undergraduate students and operationalized risk using a hypothetical investment scenario. Study 2 replicated and extended the Study 1 findings using employees and operationalized risk using their real-world investment allocations.FindingsBoth Studies 1 and 2 provided support for the negative direct relationship between NA and the riskiness of investment decisions. Study 2 found PA was marginally positively related to the riskiness of investment decisions. Financial knowledge network intensity mediated the relationship between NA and the riskiness of investment decisions in Study 2.Research limitations/implicationsThe findings suggest that employees who see the world in a generally negative light tended to have weaker financial knowledge networks, and this may be one mechanism that explains why they make low-risk investments.Practical implicationsFinancial knowledge networks can provide access to critical information regarding investment opportunities. Socialization training or social mixers can be used to help employees build and improve their financial knowledge networks.Originality/valueThe authors integrate the research on PANA, social networks, and investment decisions to illuminate the social network processes that explain how affectivity impacts the riskiness of retirement investment decisions.
Local and landscape‐scale environmental filters drive the functional diversity and taxonomic composition of spiders across urban greenspaces

Published: April 2020

Abstract

Urban patch colonization and species establishment within cities are restricted by the behavioural, life history and physiological attributes of colonizing species, in conjunction with environmental filtering processes at small and large spatial scales. To enhance the local biodiversity in urban greenspaces, these filtering processes need to be assessed so that greenspace design and management can guide establishment of local species pools.

We investigated the relative importance of local and landscape‐scale features on spider community assembly using a functional and taxonomic approach. Within the city of Cleveland, Ohio, USA, we established a field experiment wherein control vacant lots, urban meadows, and low‐ and high‐diversity pocket prairies were established across eight neighbourhoods (N = 32). Spiders were sampled during June–August of 2015 and 2016 using pitfall traps and vacuums. Spider functional diversity was assessed using null models, while local and landscape drivers were analysed via canonical partial least squares and clustered image maps.

Increased mowing was associated with lower‐than‐expected spider functional alpha and beta diversity in 2015. Patch isolation and percentage impervious surface increased the functional dissimilarity and taxonomic diversity of spiders in 2016, resulting in higher‐than‐expected overall functional alpha diversity. We also found that increasing plant height and biomass favoured spiders with large body size and decreased the abundance of small web weavers.

Synthesis and applications. Our findings suggest that increasing the amount of impervious surface in cities will act as a strong environmental filter, producing more spatially distinct spider communities at a landscape scale. Additionally, while periodic mowing in vacant lots benefits some spider taxa, it has a negative impact on the establishment of several species, mainly larger spiders and those most sensitive to disturbance. To conserve spiders and the biota depended upon them, investment in managed greenspaces such as pocket prairies that require infrequent mowing is warranted. In doing so, cities can enhance urban biodiversity and beautify local neighbourhoods.
RETRACTED: Rotenone restrains the proliferation, motility and epithelial–mesenchymal transition of colon cancer cells and the tumourigenesis in nude mice via PI3K/AKT pathway
Authors: Xue Wusong , Men Siye , Liu Renghai 
Published: April 2020

AbstractRotenone, a toxic rotenoid compound, has anti‐tumour effects on several cancers. This study aims to clarify the effect of rotenone on the proliferation, apoptosis, invasion and migration of colon cancer cells and tumourigenesis in nude mice. The present results show that rotenone significantly inhibited the proliferation, promoted the apoptosis, and suppressed the invasion and migration of colon cancer cells in a dose‐dependent manner. Rotenone inhibited PI3K/AKT pathway in LoVo and SW480 cells in a dose‐dependent manner. In addition, rotenone regulated the proliferation, apoptosis, invasion, migration and EMT of LoVo and SW480 cells through PI3K/AKT pathway. In colon cancer xenograft mice, rotenone inhibited tumour volume and weight in nude mice, inhibited PI3K/AKT pathway and EMT in vivo. Therefore, rotenone inhibited the proliferation, invasion and migration, promoted the apoptosis of colon cancer cells through PI3K/AKT pathway in vitro, and suppressed the tumourigenesis in nude mice in vivo.
Tolerance to arsenic contaminant among multidrug‐resistant and copper‐tolerant Salmonella successful clones is associated with diverse ars operons and genetic contexts

Published: April 2020

SummaryEmergence and expansion of frequent multidrug‐resistant (MDR) major Salmonella clones/serotypes has been a significant threat in the last years. Metal compounds, such as copper, commonly used in animal‐production settings, have been pointed out as possible contributors for the selection of such strains/clones. However, the scarcity of studies limits our understanding of the impact of other metal environmental contaminants as arsenic (used in insecticides/herbicides/coccidiostats). We analysed arsenic tolerance (AsT) dispersion by phenotypic and genotypic (PCR/sequencing/I‐CeuI/S1/XbaI‐PFGE/hybridization) assays among Salmonella with diverse epidemiological and genetic backgrounds. Then, to better understand ars operon genetic contexts, the whole genome of five representative strains was sequenced. We found a high dispersion of ars operons conferring AsT, especially among copper‐tolerant and relevant serotypes/clones related to pig‐production setting. The acr3‐type was found dispersed in the chromosome of diverse serotypes, including the emergent S. Rissen. Conversely, arsBII was almost confined to the MDR ST34 European clone of S. Typhimurium/S. 4,[5],12:i:‐, always along with copper/silver tolerance sil + pco clusters in an integrative conjugative element. These data suggest that AsT is an essential adaptive feature for the ecological success of these epidemic clones/serotypes and alerts for global strategies to reduce arsenic‐based compounds' impact thus preventing environmental/food contamination with frequent MDR foodborne pathogens.
Revisiting the Concept of Absorptive Capacity: The Moderating Effects of Market Sensing and Responsiveness
Authors: Bouguerra Abderaouf , Mellahi Kamel , Glaister Keith , Hughes Mathew , Tatoglu Ekrem 
Published: April 2020

AbstractThis study proposes new moderators acting on well‐established antecedents of absorptive capacity. We treat separately the two dimensions of potential absorptive capacity and realized absorptive capacity. We first examine the moderating effect of market sensing on the relationship between coordination capability and potential absorptive capacity. Then, we assess the moderating effect of market responsiveness on the links between organizational systems and socialization processes and realized absorptive capacity. We draw on multilevel analysis with data from 205 managers from the banking sector in Turkey to test our hypothesized relationships. Our contribution reveals interesting insights on the contingent effects of market sensing and responsiveness for the emergence of absorptive capacity. Market sensing moderates the relationship between coordination capability and potential absorptive capacity, while market responsiveness moderates the relationships between organizational systems and socialization processes and realized absorptive capacity. The findings provide important implications for theory and practice on developing potential and realized absorptive capacity.
Perceived arrest risk, psychic rewards, and offense specialization: A partial test of rational choice theory†
Authors: Thomas Kyle J. , Loughran Thomas A. , Hamilton Benjamin C. 
Published: April 2020

AbstractIn prior tests of Beckerian rational choice theory, the notion that individuals are responsive to the (dis)incentives associated with crime has been supported. Much of this research has comprised composite scores of perceived rewards and risks of multiple, often disparate, crime types that are then used to predict “general” offending behavior. Although the results of such prior tests are informative, we believe that this tendency has resulted in two shortcomings. First, a central component of mathematical rational choice theory is overlooked, namely, that responsivity to incentives will be crime specific. That is, offenders should prefer crime types that subjectively offer greater rewards and fewer risks relative to other crimes. Second, individual differences in offending specialization are not addressed, of which Clarke and Cornish (1985) and Shover (1996) argued rational choice theories are well suited to explain. Using a sample of serious offenders, we find that in a given time period, individuals are more likely to engage in crime types they viewed as more intrinsically rewarding and less risky compared with other crimes. Furthermore, individuals displayed greater specialization in violence to the extent they view violence as more rewarding and less risky than property offenses

AbstractBacteriocins are defined as ribosomally synthesized antibacterial peptides/proteins that either kill or inhibit the growth of other bacteria. In the present study, the physicochemical properties, mode of action, and potential use in food preservation of a novel bacteriocin BM1122 from Lactobacillus crustorum MN047 were studied. It exhibited a broad inhibitory spectrum against selected Gram‐positive and Gram‐negative bacteria. Kinetic curves revealed efficient time‐dependent bactericidal activity. Moreover, BM1122 possessed low hemolytic activity and good thermal stability between 60 and 120 °C. It was resistant to a wide range of pH (2 to 11) and proteinases. The scanning and transmission electron microscopy showed that BM1122 led to plasmolysis of Staphylococcus aureus and pore formation in Escherichia coli. Flow cytometric analysis demonstrated that BM1122 destroyed cell membrane integrity. Additionally, BM1122 could also inhibit biofilm formation and disturb the normal cell cycles of S. aureus and E. coli. Finally, BM1122 may enhance the inhibition of S. aureus and E. coli on beef meat stored at 4 °C for a duration of 10 days. These findings indicated that BM1122 had the potential for use as a natural preservative in the food industry.Practical ApplicationFresh raw meats are highly perishable products. Bacteriocin BM1122 with a broad antibacterial spectrum can inhibit the growth of microorganisms in beef meat during refrigerated storage.

Published: April 2020

SummaryGenome mining of Ascomycete sp. F53 (F53), a fungal endophyte of the traditional Chinese medicinal plant Taxus yunnanensis (Chinese yew), revealed 35 putative specialized metabolite biosynthesis gene clusters, one of which encodes a rarely seen tandem polyketide synthase pathway with close homology to azaphilone biosynthesis pathways. A novel compound, lijiquinone 1, was subsequently isolated from F53 and structurally and functionally characterized. The m/z 385 [M + H+]+ compound, comprised of a cyclohexenone side group attached to a core bicyclic ring, displayed cytotoxicity against human myeloma cells (IC50 = 129 μM), as well as antifungal activity against Candida albicans (IC50 = 79 μM) and Cryptococcus albidus (IC50 = 141 μM). Our results suggest that enzymes encoded on the lij gene cluster are responsible for the synthesis of 1 and that the medicinal properties of T. yunnanensis could be partially mediated by this novel azaphilone. This study highlights the utility of combining traditional knowledge with contemporary genomic approaches for the discovery of new bioactive compounds.
