THE current discussions to define a multi‐role aircraft for the mid 1970s have been notable for dissension of opinion on the choice between one engine or two. This remarkably basic choice has been with us since pioneer days — Lindbergh's acid comment on the value of two engines was ‘twice the trouble’, while the very fact that there are many aircraft in use of both layouts indicates that there has not been a clear case for choosing cither. Not, that is, until very recently, when statistics on the loss rate of both single and twin‐engined aircraft have confirmed that a definite margin does exist. This is the key to the whole choice between two engines or one, for it is necessary to compare not only the initial costs, but also the maintenance and operating costs, replacement of lost aircraft, and pilot training costs to achieve a realistic comparison on an overall cost basis. As with most cost‐effective arguments a strong danger exists of losing sight of primary objectives in a welter of tenuously related facts. The objectives in the choice between two engines and one is simple; which configuration fulfills an operational requirement at the least overall cost.

This chapter focuses on the physical work environment, in particular, the possibilities and limitations of biophilic design in hotel office space. Biophilic design has already gained attention in directly influencing the guest experience, but little focus has been given to workspace. Traditionally, the hospitality industry places employees' office spaces in parts of the hotel not appropriate as guest space due to lack of daylight and windows. Many studies have shown that improving the workplace with nature-based features can play a role in increasing employee well-being. Data collected from employees with both extensive managerial and back-of-house hotel experience established that employees would welcome the opportunity to work in such an environment and currently find back-of-house design basic and lacking any aesthetically pleasing elements. An understanding of the obstacles in initiating such changes was shown as well as employee initiatives to improve work spaces. This initial exploratory study concludes that the needs of employees in terms of comfort, wellbeing, motivation and work satisfaction are often overlooked when considering back-of-house spaces. There is a general understanding and expectation that management needs to develop awareness and practical initiatives to address the deficits of the physical work environment. Biophilic design can be influential in promoting a calming and restorative environment at the workplace and thus positively impacting employee motivation and performance.

Supply chain finance (SCF), which is able to manage financial flows along the supply chains effectively, has received wide attention from all over the world. Faced with the increasing number of outputs, the purpose of this paper is to investigate the SCF development over the past decades effectively, including the hot topics, knowledge diffusion trajectories and structure.

This paper adopts the keyword co-occurrence cluster and main path analysis (MPA) including four types of main paths, studying the historical development of SCF based on 2,233 papers retrieved from Web of Science during 1970–2019.

The results show that: (1) the research focuses on several aspects, including trade credit, supply chain management, procurement, health financing and sustainability, etc. and (2) trade credit financing has been the mainstream and the research focus has shifted from one-level trade credit to two-level trade credit. Recently, there is a trend to use game-theoretic models to find the best solutions for members in the supply chain.

This paper addresses the need to investigate the knowledge evolution in the SCF domain. It provides a framework to study the knowledge diffusion trajectories and structure, which helps scholars to handle thousands of papers effectively and deepen their understanding of the history, present and future trends of SCF development.

A semi‐implicit semi‐Lagrangian mixed finite‐difference finite‐volume model for the shallow water equations on a rotating sphere is considered. The main features of the model are the finite‐volume approach for the continuity equation and the vectorial treatment of the momentum equation. Pressure and Coriolis terms in the momentum equation and velocity in the continuity equation are treated semi‐implicitly. Discretization of this model led to the introducion, in a previous paper, of a splitting technique which highly reduces the computational effort for the numerical solution. In this paper we solve the full set of equations, without splitting, introducing an ad hoc algorithm. A von Neumann stability analysis of this scheme is performed to establish the unconditional stability of the new proposed method. Finally, we compare the efficiency of the two approaches by numerical experiments on a standard test problem. Results show that, due to the devised algorithm, the solution of the full system of equations is much more accurate while slightly increasing the computational cost.

Previous research warns against low-fit extensions as prone to causing negative spillover and, through it, harming the parent brand equity. Using the theory of schema-triggered affect and the link formation hypothesis, the purpose of this paper is to develop and tests predictions as to how negative spillover from low-fit extensions can be actively managed through repeated ad exposure.

A controlled experiment assesses the response of US consumers to the Dutch Heineken brand, a top 100 global brand, following sequential and repeated exposure to print ads depicting extensions for either Heineken wheat beer (i.e. a high-fit extension) or Heineken pretzels (i.e. a low-fit extension). Analytical methods include multiple regression, ANOVA, and t-tests.

The findings show that repeated ad exposure has a positive moderating effect on the magnitude of spillover from extension to brand. Second, the findings also show that repeated ad exposure changes the valence of spillover from low-fit extension to brand from negative to positive. In combination, the findings suggest that low-fit brand extensions can, when carefully managed, be a viable strategic option for market growth that is especially relevant for global brands.

This research shows that repeated ad exposure can change the valence of spillover from low-fit extensions to the parent brand from negative to positive. Future research should extend the work by considering other brands and alternative tools that managers can use to make low-fit extensions a viable strategic choice.

This study finds, in contrast to previous research, that managers should indeed consider low-fit brand extensions as a viable strategic option for brand growth. This is possible because the findings show that repeated ad exposure can be used to control potential negative spillover from a low-fit extension to parent brand. This conclusion is particularly relevant for global brands, i.e. brands for which the opportunity costs of limiting global expansion and the financial investment necessary to establish a new brand with global appeal are substantial.

This paper differs from other spillover studies by manipulating repeated ad exposure, a mechanism which the authors theoretically link to spillover and which managers can also directly influence. In doing so, this paper offers a theoretical explanation and an empirical test of how negative spillover from low-fit extensions can be managed.

Financing remains a serious concern for firms and is considered the main hurdle in the growth and development of small and medium enterprises (SMEs). Recently, a new stream of financing (SCF; supply chain finance) has emerged to meet the financing issues of SMEs. Therefore, measuring SCF is essential to support SMEs’ operations. This study aims to develop and validate the SCF scale based on extant literature.

Using a mixed-method approach, this study recruited different samples of SME entrepreneurs to confirm the internal consistency, assess construct validity and check the item structure of the SCF scale in AMOS.

The outcomes of confirmatory factor analysis demonstrated the six factors of SCF (inventory financing, working capital optimization, reverse financing, fixed assets financing, logistics financing and order cycle financing) spread over 21 items. An interitem solid structure of the SCF scale offers invaluable contributions to the supply chain management literature.

This research supports SME entrepreneurs to obtain secure financing at the best cost, mitigating the risk of default, supporting the buyers’ payment terms, providing early payment to suppliers and strengthening the firm’s value chains. SMEs can obtain financing per their requirements to support their operational business processes. Moreover, SMEs can plan, manage and control finance-related transactional activities by correctly identifying financing solutions.

The present study contributes to SCM literature by developing and validating the SCF scale. To the best of the author’s knowledge, this is the first study that redefined SCF and identified its six dimensions.

To provide a descriptive case study showing how the construction of drawings as visual metaphors can help work groups “give voice” to their emotional reactions to organizational change events, and provide groups with a vehicle for interpreting and framing their experience of organizational change.

A seven‐person focus was asked to construct a drawing that would serve as a visual metaphor for conveying the group's reaction to ongoing organizational changes within their company. Following this construction, the group engaged in a self‐interpretation of their metaphor.

The work group's feelings regarding organizational change were encapsulated in visual metaphor of “dark tower”; a metaphor of which revealed that team members shared several strong, negative emotions regarding the organizational change event. A review of how the group's changes in metaphor construction evolved over three successive drawings showed how certain elements of the metaphor came to play a central role in the team's emotional expression of organizational change events.

This case study did not attempt to provide a comparative review of metaphor constructions across work groups, nor did it include the use of other research methods, such as structured interviews, to confirm these findings.

This study illustrates how the construction of visual metaphors can be used to help researchers gain a more in‐depth understanding of the subjective, felt experience of groups during organizational change events.

The group's reflections on how their successive drawings changed over the course of the construction of their metaphor sheds light on how “visual narratives” take form over time.

Prisoners are at greater risk of infectious diseases compared to the general population. While imprisoned, it is often difficult to observe Coronavirus 2019 (COVID-19) prevention strategies such as social distancing. To the authors’ knowledge, no study has been conducted worldwide to examine the condition of female prisoners with COVID-19. Therefore, this study aims to investigate the epidemiological, clinical and imaging characteristics of prisoners with COVID-19 in Ahvaz Women’s Prison (southwest, Iran).

The data for this descriptive cross-sectional study was collected using a checklist including epidemiological information, clinical symptoms, X-ray and computed tomography scan findings of the chest, underlying diseases and the final status of all female prisoners whose COVID-19 test was positive.

This study included 139 female prisoners with COVID-19 with a mean age of 37.19 ± 12.67 years. The most common underlying diseases were hypertension (14.4%), obesity (10.8%) and chronic obstructive pulmonary disease (9.4%). The most common symptoms at the onset of the disease were myalgia (59.0%), cough (41.0%) and dyspnea (37.4%). The most common radiological symptoms were ground-glass opacity (12.9%) and atelectasis (7.2%). In terms of extension of involvement, both lungs were involved in 8.6% of patients. In terms of zonal involvement, the lower lobes were more involved (8.6%). In terms of involvement position, the most common was sub-pleural (10.1%). None of the patients died.

Because the incidence, morbidity and mortality rate of COVID-19 in the prison population are likely to differ from those of the public. This study sought to investigate the situation of prisoners with COVID-19 in Ahvaz Prison, Khuzestan Province. To the best of the authors’ knowledge, this is the first worldwide study in this regard in women’s prisons.

22q11.2 deletion syndrome (22q11.2DS) is a rare genetic syndrome involving high risk of psychiatric disorders with average intellectual functioning in the lower borderline range. Due to the cognitive and social problems many adolescents with 22q11.2DS experience, adaptions may be needed to teach these adolescents cognitive behavioral therapy (CBT) skills. The purpose of this paper is to assess psychosocial functioning in adolescents with 22q11.2DS and to adapt CBT with this group.

Totally twelve adolescents (M age=14.5 years, SD=1.4, range 12-17 years; 25 percent boys) with 22q11.2DS were recruited from a competence center for rare disorders. Their parents completed the Child Behavior Checklist and the Kiddie SADS screening interview. The adolescents participated in 7×45-minute CBT group sessions, comprising emotional awareness, cognitive restructuring tasks, and problem-solving skills.

Adolescents had poor parent-reported social and school functioning at onset. The most frequent disorders indicated by screening interviews were attention deficit hyperactivity disorder (92 percent), anxiety (58 percent), depression (50 percent), autism spectrum disorders (50 percent), and potential post traumatic stress disorder (50 percent).

The main adaptions made to CBT groups were shorter sessions, frequent breaks, and repetition of main points, limited use of written materials and items that could distract participants (e.g. balloons, papers), extensive and explicit use of turn taking, and two adult group facilitators per group.

Offers practical advice on teaching CBT skills to adolescents with 22q11.2DS, which may also be applicable to other adolescents with lower borderline intellectual functioning or intellectual disabilities.

The concept and practice of e-services has become essential in business transactions. Yet there are still many organizations that have not developed e-services optimally. This is especially relevant in the context of Indonesian Airline companies. Therefore, many airline customers in Indonesia are still in doubt about it, or even do not use it. To fill this gap, this study attempts to develop a model for e-services adoption and empirically examines the factors influencing the airlines customers in Indonesia in using e-services offered by the Indonesian airline companies. Taking six Indonesian airline companies as a case example, the study investigated the antecedents of e-services usage of Indonesian airlines. This study further examined the impacts of motivation on customers in using e-services in the Indonesian context. Another important aim of this study was to investigate how ages, experiences and geographical areas moderate effects of e-services usage.

The study adopts a positivist research paradigm with a two-phase sequential mixed method design involving qualitative and quantitative approaches. An initial research model was first developed based on an extensive literature review, by combining acceptance and use of information technology theories, expectancy theory and the inter-organizational system motivation models. A qualitative field study via semi-structured interviews was then conducted to explore the present state among 15 respondents. The results of the interviews were analysed using content analysis yielding the final model of e-services usage. Eighteen antecedent factors hypotheses and three moderating factors hypotheses and 52-item questionnaire were developed. A focus group discussion of five respondents and a pilot study of 59 respondents resulted in final version of the questionnaire.

In the second phase, the main survey was conducted nationally to collect the research data among Indonesian airline customers who had already used Indonesian airline e-services. A total of 819 valid questionnaires were obtained. The data was then analysed using a partial least square (PLS) based structural equation modelling (SEM) technique to produce the contributions of links in the e-services model (22% of all the variances in e-services usage, 37.8% in intention to use, 46.6% in motivation, 39.2% in outcome expectancy, and 37.7% in effort expectancy). Meanwhile, path coefficients and t-values demonstrated various different influences of antecedent factors towards e-services usage. Additionally, a multi-group analysis based on PLS is employed with mixed results. In the final findings, 14 hypotheses were supported and 7 hypotheses were not supported.

The major findings of this study have confirmed that motivation has the strongest contribution in e-services usage. In addition, motivation affects e-services usage both directly and indirectly through intention-to-use. This study provides contributions to the existing knowledge of e-services models, and practical applications of IT usage. Most importantly, an understanding of antecedents of e-services adoption will provide guidelines for stakeholders in developing better e-services and strategies in order to promote and encourage more customers to use e-services. Finally, the accomplishment of this study can be expanded through possible adaptations in other industries and other geographical contexts.
