Employee trust research has been criticized for restricted theoretical conceptualization, limited contextual application and low replication of measures in organizational studies. The purpose of this paper is to expand the theoretical framework underpinning individual-level organizational trust to include cognitive and socio-affective components in order to examine trust determinants in a unique cultural setting.

A national survey of 653 employees from six companies in Jamaica completed the perceived organizational support scale, perceived organizational justice scale, employee trust propensity scale and the organizational trust measure (Rawlins, 2008) after focus groups revealed the role of socio-cultural values in employee trust relationships.

Controlling for common methods variance, confirmatory factor analyses revealed that a model of organizational trust that included a combination of cognitive and socio-affective determinants was more valid in the Jamaican culture than a model comprised of cognitive determinants alone. National social values of justice and respect were significant determinants of employee trust. Results also provide validity evidence for the previously non-replicated Rawlins trust scale, thereby, providing future researchers with a measure that can be readily replicated.

Employee trust levels influenced participation and consequently restricted the sample size and industry profile of the survey. Cross-cultural trust researchers are, therefore, encouraged to design studies with similar subject loss projections.

Strict focus on the collectivistic/individualistic dimension of culture restricts researchers’ ability to measure trust effectively across a range of settings. The authors, therefore, propose the uncertainty avoidance dimension as a more valid paradigm to understand inter-cultural differences in trust orientations, particularly in restricted trust domains.

The purpose of this paper was to explore the role knowledge sharing plays in both firm-sponsored (FS) and user-generated (UG) Online Brand Communities (OBCs) on Facebook. Branding through online mediums is an under-researched area that is slowly gaining attention in the literature. In some ways, action has come first as theory struggles to catch up with technological advances. Given that social sharing behaviours (i.e. online social networking) are arguably driving the strategic direction of marketers, it is important to understand the discourse that is being communicated. One such avenue is through participation in an OBC. While it is apparent that research is growing in the OBC area, there are still areas of interest that have gained little attention.

Data were collected using netnography, an appropriate yet under-applied methodological technique used to investigate the consumer behaviour of cultures and communities present on the Internet. Specifically, Facebook Pages relating to five OBCs based on the cruise-liner P & O Australia have been chosen for this case study.

Results indicate that in both the FS and UG OBCs, knowledge-sharing was seen to have an important influence on pre-purchase decision-making. It also acted as a mechanism for trust building and sharing brand experiences and as an important encouragement to developing a sense of community among community members. A particularly interesting outcome of this research was the way in which consumers have taken on an active role in co-creating brand identity, which seemingly illuminates the role of brand management in social media.

Given that this research was conducted with a real brand, with real customers, in a real OBC, the findings also point to some important practical applications. This study has found that the role of brands in their online forums is paramount, and as such, highlights the importance of effective brand governance. The rise of technology brings increased opportunities for a brand to reach out to their consumers. This study makes a further contribution by providing insights into how the consumer–brand relationship is shaped by the communication that occurs between consumers. To this end, consumers see it as the brand’s responsibility to monitor such online platforms, thus indicating the management of OBCs needs to be at the forefront of brand management practices.

This study represents one of the earliest investigations of brand communities facilitated by social media, specifically focusing on Facebook as the communication platform. Importantly, this study increases our knowledge of consumer interaction in social media, with an emphasis towards the role that knowledge sharing contributes to OBCs and the differences prevalent between FS and UG online communities.

This paper aims to review national aeronautics and space administration (NASA’s) broad investments in electrified aircraft propulsion (EAP). NASA investments are guided by an assessment of potential market impacts, technical key performance parameters, and technology readiness attained through a combination of studies, enabling fundamental research and flight research.

The impact of EAP varies by market and NASA is considering three markets as follows: national/international, on-demand mobility and short-haul regional air transport. Technical advances in key areas have been made that indicate EAP is a viable technology. Flight research is underway to demonstrate integrated solutions and inform standards and certification processes.

A key finding is that sufficient technical advances in key areas have been made, which indicate EAP is a viable technology for aircraft. Significant progress has been made to reduce EAP adoption barriers and further work is needed to transition the technology to a commercial product and improve the technology, so it is applicable to large transonic aircraft.

Significant progress has been made to reduce EAP adoption barriers and further work is needed to transition the technology to a commercial product and improve the technology, so it is applicable to large transonic aircraft.

This paper will review the activities of the hybrid gas-electric subproject of the Advanced Air Transport Technology Project, the Revolutionary Vertical Lift Technology Project and the X-57 Flight Demonstration Project, and discuss the potential EAP benefits for commercial and military applications. This paper focuses on the vehicle-related activities, however, there are related NASA activities in air space management and vehicle autonomy activities, as well as a breakthrough technology project called the Convergent Aeronautics Solutions Project. The target audience is people interested in EAP.

Examines the mature market, defined as consumers age 50 years or older, and reviews 33 segmentation methods for the mature market and identifies five key segmentation criteria: discretionary income, health, activity level, discretionary time, and response to others. Integrates methods devised by other researchers and provides marketers with a step‐by‐step, actionable segmentation method based on these five criteria. Offers implications for managers.

The purpose of this paper is to explore the reasons why customers often cannot or do not exit a negative service encounter (lock-in) and to discuss how this affects their well-being and coping responses. This contributes to the research on how negative service encounters emerge and evolve and how such encounters impact customer well-being and subsequent responses.

An inductive, exploratory approach was used. Interviews with 20 service customers yielded over 90 detailed lock-in experiences across 25 different services. A multi-step, iterative coding process was used with a mixture of coding techniques that stem from a grounded theory approach.

Four categories of factors that caused customers to endure a negative event were identified (physical lock-in, dependency on the service, social lock-in and psychological lock-in). Customers either experienced inner turmoil (if they perceived having the option to stay or leave) or felt captive; both impacted their well-being and coping strategies in different ways. Three characteristics of negative events that caused lock-in to persist over time were identified.

This is a qualitative study that aims to identify factors behind customer lock-in, reduced well-being and coping strategies across different types of service encounters. Future research may build on these themes to investigate lock-in during specific service encounters in greater depth.

This research provides insights regarding how service providers can anticipate lock-in situations. In addition, the findings point to several ways in which frontline employees can assist customers with the coping process, during lock-in.

Customer lock-in during a service encounter is a common, yet unexplored phenomenon. This research contributes to a better understanding of why customers endure negative events and how such perceptions are reflected in their experiences and behaviors.

This paper aims to overcome the main obstacle to compare the merits of the different control strategies for fixed-wing unmanned aerial vehicles (UAVs) to assess autopilot performances. Up to now, the published studies of control strategies have been carried out over disperse models, thus being complicated, if not impossible, to compare the merits of each proposal. The authors present a worked benchmark for autopilots studies, consisting of generalized models obtained by merging UAVs’ parameters gathered from selected literature (journals) with other parameters directly obtained by the authors to include some relevant UAVs whose models are not provided in the literature. To obtain them it has been used a dedicated software (from U.S. Air Force).

The proposed models have been constructed by averaging both the main aircraft defining parameters (model derivatives) and pole-zero locations of longitudinal transfer functions. The suitability of the used methodologies has been checked from their capability to fit the short period and the phugoid modes. Previous analytical model arrangement has been required to match a uniform set of parameters, as the inner state variables are neither the same along the different published models nor between the additional models the authors have here contributed. Besides, moving models between the space state representation and transfer function is not just a simple averaging process, as neither the parameters nor the model orders are the same in the different published works. So, the junction of the models to a common set of parameters requires some residual’s computation and transient responses assessment (even Fourier analysis has been included to preserve the dominance of the phugoid) to keep the main properties of the models. The least mean squares technique has been used to have better fittings between SISO model parameters with state–space ones.

Both the SISO (Laplace) and state-space models for the longitudinal transfer function of an “averaged” fixed-wing UAV are proposed.

More complicated situations, such as strong wind conditions, need another kind of models, usually based on finite element method simulation. These particular models apply fluid dynamics to study aerostructural aircraft aspects, such as flutter and other aerolastic aspects, the behavior under icing conditions or other distributed parameter problems. Even some models aim to control other aspects than the autopilot, such as the trajectory prediction. However, these models are not the most suitable for the basic UAV autopilot design (early design), so they are outside the objective of this paper. Obviously, the here-considered UAVs are not all the existing ones, but the number is large enough to consider the result as a reliable and realistic representation. The presented study may be seen as a stepping stone, allowing to include other UAVs in future works.

The proposed models can be used as benchmarks, or as a previous step to produce improved benchmarks, in order to have a common and realistic scenario the compare the benefits of the different control actions in UAV autopilots continuously presented in the published research.

A work with the scope of the presented one, merging model parameters from literature with other (often referred in papers and websites) whose parameters have been obtained by the authors has been never published.

Physical inactivity is a global pandemic and is the fourth biggest cause of death worldwide. Numerous campaigns and initiatives have been implemented globally but yet participation levels remain static. The purpose of this paper is to offer sports providers, educators, policy makers and facilitators a new perspective on consumer values and the consumption of physical activity.

Researchers conducted a quantitative questionnaire and collected 342 responses through Facebook (social media) from the geographical region, South Wales. Data were analysed using independent t-tests to compare the means between two unrelated groups (active/non-active) against the Sport and Physical Activity Value Model value dimensions.

The findings are divided into three sections of consumption (pre, consumption, post), results identify differences of consumer values between the active and non-active respondents. For example, service values, the non-active individual have higher expectations of the servicescape and provider than active individuals, suggesting that servicescape concept is one of the key dimensions of consumer value.

The study was confined to one geographic region (South Wales) and only quantitative data were collected when further studies will require exploratory qualitative methods to have a greater understanding.

Findings from this study have been used to assist with the design and creation of an exercise class within a deprived area focussing on the values of consumption for the active and non-active. This study offers the sports provider, educator, policy maker another viewpoint of the consumption of physical activity.

Extant literature on physical activity predominately focusses on levels and there is little benefits in the way of understanding the dimensions of consumer values and the consumption of physical activity. This study contributes to this literature.

This study aims to identify supply chain (SC) management practices applied to purchasing capable of improving the resilience of the health-care SC and mitigating the effects of material and service disruption during pandemics.

The approach adopted is qualitative and is based on a systematic literature review from the ScienceDirect, Emerald, Wiley and Web of Science databases. After selecting 705 documents, filters are applied, and 52 articles present problems faced by purchasing the health-care SC during the coronavirus disease 2019 (COVID-19) pandemic.

This article suggests five propositions of resilient practices that can increase purchasing resilience in the face of pandemics such as COVID-19. The proposed practices are collaboration, flexibility, visibility, agility and information sharing, which suggest a sequence for the adoption of management practices based on the number of occurrences and importance found in the analysed studies.

This study does not find robust empirical evidence that could categorically state that the results can be replicated in organisations in general. Thus, as a continuation of research, more studies should use an empirical methodology and case analysis to organise different branches. As the human factor was decisive for the results observed in the literature, future research should dedicate part of the studies to the psychological area of professionals. Actions to combat the pandemic were implemented, impacting positively and negatively on the results obtained. Future research on combat actions could indicate which ones should be avoided.

As a result, disruptions are expected to be reduced, and consequently, the resilience of the SC will increase. Accordingly, purchasing processes and procedures can be redefined to positively influence the resilience of the health-care SC. Resilience is related to maintaining the flow of supply, as well as systems and actions aimed at mitigating the effects of disruptions in the hospital’s core business.

Health systems need to respond to society’s needs even in the face of global crises, such as the one faced during the COVID-19 pandemic. The overload in hospitals and the exponential demand for specific medicines and services in the fight against the crisis caused by the COVID-19 pandemic require enormous coordination in procurement by the purchasing sector. This planning aims to ensure that the care provided by health services maintains the flow of value that serves hospitalised patients.

This study introduces a new approach to the recurrent problem of disruption of the health-care SC during a pandemic using a combination of five important management practices. This proves useful for mitigating disruptions and their effects on the health-care SC.

Man has been seeking an ideal existence for a very long time. In this existence, justice, love, and peace are no longer words, but actual experiences. How ever, with the American preemptive invasion and occupation of Afghanistan and Iraq and the subsequent prisoner abuse, such an existence seems to be farther and farther away from reality. The purpose of this work is to stop this dangerous trend by promoting justice, love, and peace through a change of the paradigm that is inconsistent with justice, love, and peace. The strong paradigm that created the strong nation like the U.S. and the strong man like George W. Bush have been the culprit, rather than the contributor, of the above three universal ideals. Thus, rather than justice, love, and peace, the strong paradigm resulted in in justice, hatred, and violence. In order to remove these three and related evils, what the world needs in the beginning of the third millenium is the weak paradigm. Through the acceptance of the latter paradigm, the golden mean or middle paradigm can be formulated, which is a synergy of the weak and the strong paradigm. In order to understand properly the meaning of these paradigms, however, some digression appears necessary.
