The Impact

The Theory of Planned Behavior (TPB) provides a conceptual model for use in assessing behavioral intentions of humans. Agent based social simulations seek to represent the behavior of individuals in societies in order to understand the impact of a variety of interventions on the population in a given area. Previous work has described the implementation of the TPB in agent based social simulation using Bayesian networks. This paper describes the implementation of the TPB using novel learning techniques related to reinforcement learning. This paper provides case study results from an agent based simulation for behavior related to commodity consumption. Initial results demonstrate behavior more closely related to observable human behavior. This work contributes to the body of knowledge on adaptive learning behavior in agent based simulations.

The Impact

In this paper, the authors discuss creativity and the impact it might have on teaching and learning. The authors believe that imaginative play, at all ages, helps all people (children especially) create healthy environments and spaces that expand their learning. The authors contend that teaching for imagination—which asks little more than creating and trusting an ecological space that engenders it—seldom is considered a priority. Given the emphasis on creativity in the real world and the virtual digital world, the authors believe it is important to add to the body of knowledge through continued research in this field.

Community Dwelling Older Adults

Background: Information on the body composition of inhabitants of remote communities during the SARS-CoV-2 pandemic is limited. Using a longitudinal population-based study design, we assessed the association between SARS-CoV-2 infection and changes in body composition. Methods: Community-dwelling older adults living in a rural Ecuadorian village received body composition determinations before and 1 year after the pandemic as well as serological tests for detection of SARS-CoV-2 antibodies. The independent association between SARS-CoV-2 infection and abnormalities in body composition at follow-up was assessed by fitting linear mixed models for longitudinal data. Results: Of 327 enrolled individuals, 277 (85%) received baseline and follow-up body composition determinations, and 175 (63%) of them became SARS-CoV-2 seropositive. Overall, diet and physical activity deteriorated during the follow-up. Multivariate random-effects generalized least squares regression models that included the impact of time and seropositivity on follow-up body composition, showed that neither variable contributed to a worsening in body composition. Multivariate logistic regression models disclosed that the serological status at follow-up cannot be predicted by differences in body composition and other baseline covariates. Conclusions: Study results suggest no increased susceptibility to SARS-CoV-2 infection among older adults with abnormal body composition and no significant changes as a result of worse physical activity and dietary habits or seropositivity during the length of the study. Together with a previous study in the same population that showed decrease in hand-grip strength after SARS-CoV-2, results confirm that dynapenia (and not sarcopenia) is associated with SARS-CoV-2 infection in older adults.

PurposeThis paper aims at providing an overview and synthesis of the existing body of knowledge about greenwashing. Special attention is paid to the articles directly linked with agriculture, food industry and food retail.Design/methodology/approachA bibliometric analysis was performed over 351 documents extracted from the WoS database, using SciMAT and VOSviewer software programs.FindingsThree periods in the academic literature about greenwashing can be distinguished: ground-setting (2003–2010), trail-blazing (2011–2015) and remarkable growth (2016–2020). Along this evolution, a body of knowledge which stemmed from the literature about CSR has achieved a major development, deploying different research lines such as stakeholders' management, marketing and communication and audit. A specific analysis of the academic literature about greenwashing in agriculture, food industry and food retail has been carried out, showing a need for further development.Social implicationsThe development of scientific knowledge about greenwashing puts this social claim on the spotlight of business management studies, helping to fight greenwashing and, this way, to reduce the environmental impact of corporate activities. Studying greenwashing will help to reduce its frequency and, therefore, heal the planet.Originality/valueSome previous studies have provided systematic reviews of the literature using different approaches, but they did not untangle the intellectual structure and the evolution of the body of research about greenwashing. This article originally provides a thorough analysis of these aspects, as well as a closer look at the impact of greenwashing practices in the academic literature regarding agriculture, food industry and food retail.

The Impact

Over the next 35 years, the population of Switzerland is expected to grow by 25%. One possible way to accommodate this larger population is to transform smaller cities in Switzerland through the direct intervention of urban planners. In this work, we integrate agent-based simulation models of people flow, mobility and urban infrastructure with models of the electricity and gas systems to examine the increase of the density of existing residential zones and the creation of new workplaces and commercial activities in these urban areas. This novel simulation framework is used to assess, for the year 2050, two different scenarios of urbanization in a region with small urban areas. It is shown that a densification scenario, with a preference for multi-dwelling buildings, consumes 93% less land than a sprawl scenario, with a preference for single-family houses. The former scenario also accommodates 27% more people than the latter scenario, as there is a higher penetration of battery electric vehicles – and therefore reduced air pollution from the transportation sector – and also a larger shift of commuters to the use of public transport. However, in the former scenario, the commuting time is 20% longer. The outcome of this work demonstrates how this novel simulation framework can be used to support the formulation of policies that can direct the transformation of urban areas.

Purpose The purpose of this paper is to use the Macau gaming industry as a case study to discuss the multifaceted relationships involving experiential quality, experiential relationship quality and future experiential intentions. Design/methodology/approach In this study, 566 usable responses were collected from casino gamblers who had gaming experience in one casino of Macau. Findings According to the study results, the dimensions of experiential quality (hedonics, involvement, surprise, fun, gambler contact and physical environment) had a positive effect on experiential satisfaction, which in turn led to experiential trust. Both experiential trust and experiential satisfaction positively influenced experiential commitment. Moreover, experiential trust, experiential satisfaction and experiential commitment positively affected future experiential intentions. Originality/value The main contribution of this research is that it has added to the body of knowledge about the interplay between the dimensions of experiential quality, the dimension of experiential relationship quality and future experiential intentions, which can be fruitful for the gaming industry.

The Impact

Decision-making processes are the utmost important to steer the organizational change whenever business process workarounds are attempted during operational times. However, to decide the non-compliant situations, e.g., bypasses, social resistance, or collusion; the business manager demands contextualized and correct interpretations of the existing business process redesign options to cope with workarounds. This article explores the need to aid the decision-making process with a full constructional perspective to optimize the business processes redesign. So, the Markov decision process is combined with the body of knowledge of business processes, in specific, the concepts of designing enterprise-wide business transactions. This methodology supports the management initiatives with more knowledge about the value of business processes redesign. A classical chain of Order-to-Cash business processes (the order, the production, the distribution and the selling of goods) illustrate the benefits of this quantitative approach. Results obtained for business processes redesign in reaction to workarounds are reported. The analysis results show that this approach can anticipate the sub-optimal solutions before taking actions and highlights the impact of discount factors in the final obtained value. The contribution of this novel conceptual integration to the business processes community is the forecast of value function of business transaction redesign options when facing non-compliant workarounds. From related literature, business processes compliance usually comprises offline computation and the redesign is only considered in the forthcoming business processes instances. This article is innovative in the sense that it anticipates the value impact of a redesign, allowing more effective decisions to be taken.

Study Results

Prequalification (PQ) is a significant process in the selection of private sector for the delivery of civil infrastructure projects.  But, the extant literature, for the most part, focused on PQ of construction projects.  The need for setting proper PQ, i.e., criteria and corresponding limits in public-private partnership (PPP) infrastructure projects, especially municipal solid waste (MSW) projects is still a lacuna in the body of knowledge of Indian PPPs.  To this end, this paper identified PQ criteria using content analysis of the sample of MSW projects. These identified criteria were subjected to regression modeling. These results were compared with the results of well-matured highway sector to draw comparison with MSW projects.  The practical implications are that urban local bodies (ULBs) are but less competent and less uniform in the rationale of setting the PQ criteria and limits.  This paper suggests that lowering the technical and financial PQ limits considering the market orientation will help in bringing more competitive bidders into the bidding.   Since MSW is in a very nascent stage of application of PPP, the study results could lay directions for future project procurement to discern right limits for right project sizes.

Purpose The purpose of this paper is to test the influence of branded premiums or branded free gifts (e.g. a free of charge suitcase of a well-recognised brand) on tourism destination promotion. Specifically, the impact of brand name and price value of a branded premium on promoting a tourism destination was examined. Design/methodology/approach This research uses two experiment-based studies, applying a between-group experimental design. Findings The results revealed that appreciation leads to intention to visit the promoted destination when the branded promotion is offered. When a destination promotional offer contains a branded premium, consumers respond more favourably to the brand name of the premium than the price value of the premium. This finding applies to consumers’ responses to both the destination and the premium. Research limitations/implications This research adds to the body of knowledge on tourism destination promotion and the branding literature, specifically with promotional and branded premiums. Practical implications Mutual benefits can be obtained by both tourism destination marketers and premium marketers. Originality/value This research highlights the importance of branded premiums in tourism destination promotional offers. This research also shows the influence of the price value of a premium’s brand name in a tourism destination promotional offer.

The oriented perforating is the essential technique to guide the refracture reorientation, but the influence of the oriented perforation design on the refracture steering radius is still unclear. In this paper, the factors influencing the refracture reorientation were studied by simulation models and experiments. The effects of initial fracture, well production, and perforations on the refracture initiation and propagation were analyzed. Three-dimensional finite element models were conducted to quantify the impact of perforation depth, density, and azimuth on the refracture. The large-scale three-axis hydraulic fracturing experiments guided by oriented perforations were also carried out to verify the fracture initiation position and propagation pattern of the simulation results. The research results showed that perforations change the near-wellbore induced stress distribution, thus changing the steering radius of the refracture. According to the simulation results, the oriented perforation design has a significant influence on the perforation guidance effect and refracture characteristics. Five hydraulic fracturing experiments proved the influence of perforating parameters on fracture initiation and morphology, which have a right consistency between the simulation results. This paper presents a numerical simulation method for evaluating the influence of the refracture reorientation characteristics under the consideration of multiple prerefracturing induced-stress and put forward the oriented perforation field design suggestions according to the study results.

Purpose This exploratory paper aims to examine the literature on the impact of COVID-19 on safeguarding adults practice. Design/methodology/approach A literature search was carried out in recently published articles to locate literature relating to COVID-19 and safeguarding adults in the UK and internationally. This included policy guidance and law, to describe the existing knowledge base, gaps in practice and areas that may require further research. Findings The findings suggest that measures to curb the spread of the COVID-19 pandemic gave rise to remote working and virtual safeguarding practice. The findings highlight the need for empirical research into the impact of virtual safeguarding adults assessments and effective ways to support the needs and outcomes of those who may be at risk of or experiencing abuse and neglect while shielding, socially isolating or when working in an environment where social distancing is required. Research limitations/implications The paper is based on a review and analysis of published documents and not on other types of research. Originality/value Little is known about effective safeguarding adults practice in the era of shielding, self-isolation, social distancing and remote working. The paper adds to the body of knowledge in the field.
