Assessing Adoption Factors for Additive Manufacturing: Insights from Case Studies
No full textBackground: Research on Additive Manufacturing [AM] provides few guidelines for successful adoption of the technology in different market environments. This paper seeks to address this gap by developing a framework that suggests market attributes for which the technology will successfully meet a need. We rely on classical technology adoption theory to evaluate the challenges and opportunities proffered by AM. Methods: We apply a framework of technology adoption and assess these parameters using seven case studies of businesses that have successfully adopted AM technology. Results: We find that successful business adoption is highly associated with the relative advantage of AM to rapidly deliver customized products targeted to niche market opportunities. Conclusions: Our findings provide a decision framework for AM equipment manufacturers to employ when evaluating AM technology across various market environments. All five adoption characteristics were found to be important however, the primary decision criterion is based on the relative advantage of AM over other, traditional, technologies. From a practitioner perspective, our research highlights the importance of AM in attaining a competitive advantage through responsive, customized production which can address the needs of niche markets
Anxiety and Spatial Navigation in Williams Syndrome and Down Syndrome
No full textIndividuals with Down Syndrome (DS) and individuals with Williams syndrome (WS) present with poor navigation and elevated anxiety. The aim of this study was to determine the relationship between these two characteristics. Parent report questionnaires measured navigation abilities and anxiety in WS (N = 55) and DS (N = 42) as follows. Anxiety: Spence Children’s Anxiety Scale and a novel measure of navigation anxiety. Navigation: Santa Barbara Sense of Direction Scale (SBSOD) and a novel measure of navigation competence. Most individuals were not permitted to travel independently. A relationship between navigation anxiety and SBSOD scores (but not navigation competence) was observed for both groups
Care coordination, consistency and continuity: the case of the key worker role in children's cancer care
No full textPurpose: The overall aim was to evaluate the key worker role across principal treatment centres for children with cancer in England, Wales and Scotland.Methods: Mixed-methods case study gathering data from multiple perspectives using questionnaires, interviews, focus groups and reports/performance documents over a two-year period. Framework approach was adopted to analyse transcripts and documentary data. Results: Participants included: 22 nurse specialist key workers, 103 parents, 85 professionals and 10 children/young people. Qualitative and quantitative data were weaved together, to best illuminate key worker services. Four main models of care were described as well as the context of care and process of care. Key working effectiveness centred around three pillars: care coordination; expert knowledge, experience and expertise; relationship. These were essential to improved family experience, emotional wellbeing, and delivery of individualised care closer to home. Conclusions: The role is complex and diverse, responding to local needs. Certain conditions, (e.g. high caseload) placed limits on enacting the three pillars, diminishing the positive experience of families. When they worked well, key workers reduced the fragmented nature of services and families placed great value on keeping the same key worker from diagnosis into long-term care. Retaining these roles, where already in place, or including, if not, we would recommend, factoring into budgets to sustain and expand such roles.</p
Patient satisfaction with medication consultations and medicines information provided by nurses working autonomously in sexual health services: A questionnaire study
No full textTo compare the satisfaction of patients managed by independent nurse prescribers with that of patients managed by nurses using PGDs with respect to experience of the consultation and information received about the medication.Survey.Patients receiving medications from nurses in five urban sexual health services in the United Kingdom completed validated questionnaires immediately after the consultation, September 2015-August 2016. Scores of independent nurse prescribers and nurses using patient group directions were compared about consultation experience (5 items) Satisfaction with Information about Medicines (SIMS 16 items scale).Of 808 patients receiving medications, 393 (48.6%) received questionnaires and 380 were returned (independent nurse prescribers 180 of 198, 90.9%; patient group directions 173 of 195, 88.7%). Patients in both groups reported high levels of satisfaction. About the consultation experience, patients found nurses friendly/ approachable (>99%), instilling confidence and trust (>99%) and explaining reasons for medications clearly (97%). Satisfaction with medication information: Of 348 (92%) respondents completing SIMS, the overall mean score was 13.4 of maximum 16 (no difference between groups, t-test, p = .63).Patients were highly satisfied with nurse consultations and information around medications regardless of whether they were managed by independent nurse prescribers or nurses using patient group directions.Findings provide evidence in support of autonomous provision of medications by nurses in sexual health clinics
Cyber-physical traveler performances and Instagram travel photography as ideal impression management
No full textWhile there is significant existing research linking travel photography to self-presentation, it is the effects of ‘Instagrammability’ that mobilize significant shifts in the motivations and behaviours of tourists. This paper applies Goffman’s (1956) notion of impression management unfolding as a performance, with both front- and backstage characteristics. This research finds that the frontstage in this context is identified as the cyber behaviour, while the backstage encapsulates the physical manifestations that occur ‘behind the scenes’ to ‘get the shot’. By employing both content analysis and ethnography, new social norms of using travel images for impression management were identified in which there is a clear motive to match the ‘Instagram aesthetic’. A refreshed code of choreographed movements as photographic practices has emerged that did not exist before the popularization of Instagram. Less than 2% of photos analyzed solely feature the landscape, reinforcing the shift to self-presentation strategies as the foremost importance.</p
An Improved EPA based Receiver Design for Uplink LDPC Coded SCMA System
No full textSparse code multiple access (SCMA) is an emerging paradigm for efficient enabling of massive connectivity in future machine-type communications (MTC). In this letter, we conceive the uplink transmissions of the low-density parity check (LDPC) coded SCMA system. Traditional receiver design of LDPC-SCMA system, which is based on message passing algorithm (MPA) for multiuser detection followed by individual LDPC decoding, may suffer from the drawback of the high complexity and large decoding latency, especially when the system has large codebook size and/or high overloading factor. To address this problem, we introduce a novel receiver design by applying the expectation propagation algorithm (EPA) to the joint detection and decoding (JDD) involving an aggregated factor graph of LDPC code and sparse codebooks. Our numerical results demonstrate the superiority of the proposed EPA based JDD receiver over the conventional Turbo receiver in terms of both significantly lower complexity and faster convergence rate without noticeable error rate performance degradation
From pandemic to endemic? Learning lessons from a global contagion
No full textCovid-19 has had the most profound impact at all levels: globally, nationally, and individually, across every sector imaginable. The 'spectrum of responses' represents an emerging structure that decision-makers have created and implanted, to help control the unpredictable nature of the pandemic. From shut down to lock down, from time and location-based unlocking, and back to full release, local and national communities alike have struggled - and some have succeeded - in their responses to Covid's epidemiological impacts. Every state, every individual has been propelled back and forth along this spectrum, and the spectrum itself has been swiftly made, and overhauled by governments attempting to stay one step ahead of the spread, in lockstep with the swiftest developments in immunology and virology yet seen this century. But the spectrum cannot capture everything, including the tremendous economic and social impacts that Covid has had on societies, and indeed the most appropriate steps to take next
Relational Communication Style in Business, Marketing and Service Interactions
No full textVerbal communication (i.e. text or spoken language use) can be evaluated under two aspects, namely content and style. Thereby, communication style is independent of the content (what is conveyed) and consist of stylistic elements concerning how a sentence is expressed. This dissertation concentrates on three different aspects which influence how interactants communicate aka factors influencing communication style: (1) the relationship between interactants i.e. doctors and patients, (2) the interaction as a representation of a relationship i.e. marketing communication, and (3) individual differences i.e. empathy.First, synthesizing marketing communication research in a meta-analytic review, shows that communication style in marketing can be summarized containing five dimensions, namely, arousal, composure, dominance, intimacy and task-orientation. The influence of the five communication styles on marketing outcomes, attitude, intention and behavior is established and boundary conditions are examined.Second, the framework of communication styles deduced in the meta-analysis is used to examine how these dimensions influence perceptions of patients about their relationship with a health service professional. Using customer reviews of patients and exploiting text analysis to extract the dimensions in the verbatim review comments provides evidence for the dimensional structure of communication styles in doctor-patient relationships. Further, the individual and joint effects of the dimensions are linked to patient satisfaction.Third, the concept of empathy, being a relevant variable in communication, is examined through bibliometric techniques. Applying bibliographic coupling shows that research on empathy in the business field is built on five clusters, two concept related clusters (perspective taking and empathic concern), and three content related clusters (ethics, sales and leadership). Content and co-word analysis provides additional insights, e.g. similarities or differences in conceptualization, definitions, keywords or methodologies, within and across clusters. Further, for all three topics regarded in this dissertation, research gaps are identified and translated into future research directions
Impact of Socio-Economic Factors on Nutrition Efficiency: An Application of Data Envelopment Analysis
No full textBackground: Paying particular attention to sustainable food consumption in low-income households is essential for increasing human health. Due to the growing population globally, this concept will likely become more serious soon.Methods: Following the importance of optimizing food consumption for sustainability, in this study, a novel methodology is introduced for calculating nutrient intake efficiency and determining choices of food in different locations. The impact of socio-economic factors on nutrition efficiency is assessed. Data Envelopment Analysis (DEA) as a well-known linear programming (LP) and a Tobit model are used to achieve the goals. Household Consumption and Expenditure Surveys (HCESs) of 30,000 rural and urban Iranian households in all provinces in 2016 are analyzed. A Nutrient Efficiency Map (NEM) of Iran was depicted by GIS software.Results: The results showed that many townships had nutrient efficiency scores of less than 70%. Northeast townships had the lowest scores, with an efficiency score of less than 50%. Overall, townships have lower efficiency in the North (seaside cities), East (desert cities), and North East (isolated cities) when compared with other areas.Conclusion: Therefore, it is suggestible that the government should modify the support policies and the protection packages based on social, geographical, and cultural status
A Mixed Integer Network DEA with Shared Inputs and Undesirable Outputs for Performance Evaluation: Efficiency Measurement of Bank Branches
No full textConventional DEA performs like a " black box " and provides no information about sub-processes. In some cases, such as banks, providing services is made up of interactive and interdependent processes. Also, in real world applications, inputs could be shared among these sub-processes. Moreover, due to the characteristics of some variables, such as number of employees, only integer values could be assigned to them. Hence, to address these shortcomings, in this study, a mixed integer network DEA (MI-NDEA) with shared inputs and undesirable outputs has been proposed to evaluate the efficiency of decision making units. The proposed model considers integer values for some of the input variables. Also, it assumes that some inputs are shared among different stages of the production process. To illustrate the capability of the model, the efficiency of " Internet banking " , " profitability " , " production " and " overall " performance of a set of bank branches have been evaluated and results are discussed. The results indicate that the mean of overall efficiency for all branches is high. However, some branches are not efficient enough in the " Production " stage or " Profitability " stage. To identify the source of inefficiency in such branches, projection values have been calculated and recommendations have been made for policy makers
