    In COVID-19 Health Messaging, Loss Framing Increases Anxiety with Little-to-No Concomitant Benefits: Experimental Evidence from 84 Countries
    (2022) Sarioguz, Eyluel; Karaarslan, Cemre; 36185503
    The COVID-19 pandemic (and its aftermath) highlights a critical need to communicate health information effectively to the global public. Given that subtle differences in information framing can have meaningful effects on behavior, behavioral science research highlights a pressing question: Is it more effective to frame COVID-19 health messages in terms of potential losses (e.g., "If you do not practice these steps, you can endanger yourself and others") or potential gains (e.g., "If you practice these steps, you can protect yourself and others")? Collecting data in 48 languages from 15,929 participants in 84 countries, we experimentally tested the effects of message framing on COVID-19-related judgments, intentions, and feelings. Loss- (vs. gain-) framed messages increased self-reported anxiety among participants cross-nationally with little-to-no impact on policy attitudes, behavioral intentions, or information seeking relevant to pandemic risks. These results were consistent across 84 countries, three variations of the message framing wording, and 560 data processing and analytic choices. Thus, results provide an empirical answer to a global communication question and highlight the emotional toll of loss-framed messages. Critically, this work demonstrates the importance of considering unintended affective consequences when evaluating nudge-style interventions.

    How patients perceive healthcare services: A case of Ayub Teaching Hospital, Abbottabad - Pakistan. SERV Service QUAL Quality
    (2018) Ali, Muhammad
    A field study was conducted in Ayub Teaching Hospital in the outpatient department, to evaluate the level of service quality offered by the healthcare services with a view to identifying the relationship between service quality dimensions and overall service quality. The researchers used the SERVQUAL instrument for the purpose of assessing the quality of the service offered by the healthcare workers at the outpatient department in Ayub Teaching Hospital. A sample of 246 patients in the outpatient department participated in the questionnaire survey. Descriptive statistics were used to find out mean values and variance between actual values from perceived values. To assess the strength of model regression, the aforementioned technique was adopted. The study results showed that there exists a gap between patients' expectation and actual services offered by the healthcare workers. There were five dimensions that were assessed: tangibles, reliability, responsiveness, assurance and empathy. The results revealed that patients are dissatisfied with three dimensions (tangibles, reliability and assurance), but they are satisfied with the other two dimensions (responsiveness and empathy). This research adopts the marketing concept to measure the healthcare services. The SERVQUAL tool was modified as per need to meet the requirements in accordance with the nature and scope of the research. Patients' attitudes toward service quality dimensions were the concern of the research. To get a comprehensive evaluation of service quality, healthcare providers have to be considered in future research. Based on the findings of this study, Ayub Teaching Hospital's (ATH) management is in a position to recognize the patients' perceptions about the healthcare services and offer them service accordingly. Results can be used by management and government policymakers regarding healthcare to bring better and more effective services. Consequently, based on the results, new structure can be designed by adopting strategies that improve the quality of services in order to provide effective services and gain patients' satisfaction and propensity to further recommend the services of healthcare to other patients. This study investigates the healthcare quality in a small area in Pakistan. Pakistan is a developing country. Future research can adopt the SERVPREF technique, which is a more developed technique than SERVQUAL in order to measure service quality as it provides a two-factor solution for the dimensionality of health service quality.

    A Cross-Sectional Survey on Consequences of Nurses' Burnout: Moderating Role of Organizational Politics
    (2016) Basar, Ufuk; Basim, Nejat; 0000-0003-0008-5131; 26988276; ABD-9381-2021; J-2510-2016
    AimThe aim of the study was to assess whether perceptions of organizational politics (defined as self-serving behaviours at the expense of others) influence the prospective associations between nurses' burnout and its consequences, namely, intention to quit and neglect of work. BackgroundResearchers have previously investigated relationships between nurses' burnout, intention to quit, neglect of work and perceptions of organizational politics in different research models and from different perspectives. As far as we know, no studies have considered whether nurses' perceptions of organizational politics moderate the influence of burnout. DesignA cross-sectional survey using self-report questionnaires. MethodData were collected by questionnaire from a sample of 456 nurses from six private hospitals in Ankara, Turkey in March 2015. Four different previously designed scales were used to measure research variables (burnout, intention to quit, neglect of work and perceptions of organizational politics). Following confirmatory validity and reliability analyses of data collection instruments, descriptive statistics for each research variable were analysed. Structural regression models were created to assess relationships among variables. FindingsBurnout resulted in intention to quit and neglect. Intention to quit partially mediated the association between burnout and neglect. Burnout gave rise to intention to quit slightly more strongly in nurses who had greater perceptions of organizational politics. ConclusionThis study uncovers and emphasizes the moderating role of perceptions of organizational politics in consequences of burnout. This may help hospital managers and nurses to improve costs, efficiency, satisfaction and productivity.

    Transcultural Memory of the Nation in Caryl Phillips's A Distant Shore
    (2022) Kirpikli, Deniz; https://orcid.org/0000-0002-0330-593X
    This study argues that Caryl Phillips's A Distant Shore (2003) uncovers Britain's transcultural memory of the imperial past through the journey of the refugee protagonist Solomon/Gabriel from Africa to England. The unlikely encounter between Solomon/Gabriel and Dorothy, a white Englishwoman, in a setting inhospitable to both of them opens up a narrative space to explore the imperial legacy that persists in contemporary racism in Britain. The novel achieves this through a mnemonic narrative strategy based on a fragmented structure with a narrative voice shifting back and forth in time and place. In doing so, the novel contests the idea of the homogeneous nation by drawing parallels between the Middle Passage and refugee flow from Africa. This study will, thus, demonstrate that the novel offers a transcultural perspective on memory and nation by illustrating the cross-border reach of memories that are ignored by national essentialism.

    Love is Not Blind: Investigating A Love-Hate Transition Among Luxury Fashion Brand Consumers
    (2021) Kashif, Muhammad; Devrani, Tulay Korkmaz; Rehman, Aisha; Samad, Sarminah
    Purpose There is extensive research where consumer emotions of brand love and brand hate are investigated. However, the studies where a transition in consumer-brand emotions is explored are scant. This paper aims to investigate the mediating effect of brand jealousy in the relationship between brand love and brand hate among luxury fashion brand consumers. Also how value expressiveness moderates the relationship between brand hate and negative word of mouth (NWOM) is examined. Design/methodology/approach The study is based on a cross-sectional survey conducted among 273 luxury fashion consumers from Pakistan. The structural equation modeling (SEM) technique is employed to test the proposed hypotheses. Findings All the proposed hypotheses are supported. Brand jealousy mediates the relationship between brand love and brand hate. Furthermore, value expressiveness buffers the relationship between brand hate and NWOM. Practical implications The luxury fashion marketers should focus on strengthening the symbolic identity of a luxury fashion brand via advocating its visual elements. Moreover, there is a need to advertise luxury fashion brands as exclusive to individual customers. Finally, some rewards can be offered to consumers to generate positive word of mouth (WOM) about luxury fashion brands. Originality/value The study of an emotional transition among luxury brand customers via a mediating role of brand jealousy is a unique theoretical contribution. Moreover, the moderating role of the value-expressiveness function examining the hate-to-NWOM path is also unique to this study.

    Molecular Biology Inspired Mutual Authentication Schemes for Wireless Body Area Network
    (2021) Ozkoc, Esma Erguner; Mannion, Mike
    As the use of Wireless Body Area Network (WBAN) becomes widespread, concerns about the security of the data they produce and transmit are also increasing. One of the basic security requirement for WBAN communication include authentication. In this study, a certificate-less mutual authentication scheme is proposed. The scheme was developed using pseudo-DNA cryptography techniques (due to its features such as randomness and rule less, easily generated and accessible, similarity to the binary system and no need for high-tech laboratory conditions) in addition to modern cryptography techniques, to increases the level of security without adding additional computational costs to the system.

    Validity and Reliability Evidence of Professional Obsolescence Scale According to Different Test Theories
    (2021) Altun, Sedagul Akbaba; Buyukorturk, Sener; Seheryeli, Merve Yildirim
    This study aims to develop a scale that will determine the factors causing professional obsolescence in the field of education. In this context, the Professional Obsolescence Scale (POS) has been developed to determine the professional and organizational obsolescence of primary, secondary and high school administrators. In this scale development process, steps were followed in line with the suggestions of Crocker and Algina (2006) and Cronbach (1984). Firstly, 63 items were prepared and 991 school principals participated the study. R (version 4.0.1) software was used to analyze the data. Item and test parameters and information functions have been estimated using Samejima's Graded Response Model based on Item Response Theory. Principal Axis Analysis was performed for the construct validity of the scale, and four-dimensions structure with 47 items has been obtained. These dimensions are named as "Being Open to Professional Development", "Job-Ability Harmony in Profession", "Organizational Support in Professional Development", "Professional Burnout". The scores obtained from each dimension are evaluated within themselves. It has been observed that each dimension fulfills the conditions of unidimensionality, local independence, model-data fit and parameter invariance. According to the Classical Test Theory, Cronbach Alpha coefficients are between 0.807 and 0.945. The Stratified Alpha coefficient calculated for the whole scale is 0.94. According to the Item Response Theory, the marginal reliability coefficients were between 0.857 and 0.936 and the empirical reliability coefficients were found between 0.854 and 0.938.

    Introduction of a new method for retailing and marketing research: the case of shopping malls
    (2020) Sozen, Cenk; Devrani, Tulay
    Purpose The purpose of this study is to suggest an unusual method that may help researchers to examine from the real-time movements of consumers among stores located on any kind of shopping location. We assumed shopping behavior of individuals as a complicated network representing their interactions with multiple types of stores - brands. Shopping malls were chosen to test this alternative method. Closely located stores in these organizations give researchers a chance to investigate patterns of interactions of customers in relation to brands. Therefore, we decided to develop an unusual method to examine customers' behavior in these organizations. Design/methodology/approach This study suggests that circulation patterns of customers in a shopping location may provide valuable information to decision makers. The applicability of this technique was tested on 700 consumers visiting stores of a supper-regional shopping mall, located in Ankara, Turkey. Paths of the customers in a specific type of mall were determined, and their interactions with the stores were analyzed by using social network analysis techniques. The brands having key positions in the network were compared with the brand configuration of high- and low-performer malls serving to similar markets. Findings The results of the network analyses were used to understand whether this method could be beneficial for the ideal tenant mix problem of shopping malls. Findings suggest that the performance of malls depends on fitness to customer paths, and the malls, which didn't have the key brands at the initial stage, could not adapt themselves later. Findings of the case study verified that this technique might offer a solution to this well-known dilemma of the retailing sector and may have several implications. Originality/value These types of data are very valuable, especially for retailing research and the industry, because very critical knowledge such as traffic among retail stores, key central brands, ideal location of stores, consumption tendencies of different customer groups and symbiotic or competitive relations among retailers can be obtained. This method may also have broad implications in other fields of research such as location analysis, decision support systems and property management as well as marketing and retailing.

    Single-Machine Order Acceptance and Scheduling Problem Considering Setup Time and Release Date Relations
    (2020) Bicakci, Papatya S.; Kara, Imdat; Sagir, Mujgan
    This paper focuses on a make-to-order production system, where rejection of some orders is inevitable due to limited production capacity. In such a system, accepting all orders may cause overloads, order delays, and customer dissatisfaction. For this reason, firms tend to reject some orders. The order acceptance and scheduling problem is defined as deciding simultaneously which orders to be selected and how to schedule these selected orders. An extension of this problem with sequence-dependent setup times and release dates has been rarely studied, and the existing studies suggest that setup activities wait for the release date to be performed. However, in real production environments this may not be the case. Therefore, this paper examines the relationships between setup times and release dates considering the overall scheduling literature. Previous scheduling studies define two different relationships concerning setup times and release dates. One of them considers setup time is completely dependent on release date, and the other one claims that they are completely independent. In this paper, a new relationship is addressed to propound that setup time may be partially dependent on the release date. The paper also proposes a new mixed integer linear programming formulation withO(n(2)) binary decision variables andO(n(2)) constraints. It includes a detailed computational analysis by solving available instances in the literature, which suggests that existing formulation can solve the test problems to optimality with up to 10 orders in a given time limit. Our proposed formulation, however, can solve the test problems to optimality with up to 50 orders within the same time limit. According to the findings, our approach seems to be more suitable for real-life applications, and the proposed formulation is extremely faster than the existing one.
