    “At Least, at the border, i am killing myself by my own will”: migration aspirations and risk perceptions among Syrian and Afghan communities
    (Routledge Journals, Taylor and Francis Ltd, 2023) 0000-0002-1498-0025; 0000-0002-9426-428X; Department of International Relations; N/A; Önay, Ayşen Ezgi Üstübici; Taşan, Eda Kirişçioğlu; Faculty Member; PhD Student; College of Administrative Sciences and Economics; Graduate School of Social Sciences and Humanities; 238439; N/A
    It is well-documented that border controls make migration journeys riskier for people on the move. Policymakers construe deaths in migration journeys as resulting from the individual risk-taking attitudes of migrants. However, risks involved in migration journeys are not only related to border control measures. Based on the analysis of 30 semi-structured interviews conducted with Syrian and Afghan migrants in Turkey, we embrace a social constructionist approach to unpack how migrants form their aspirations based on their risk perceptions. Our findings explain why some migrants would still move onwards despite violent borders while others stay or search for "safer" ways for onward migration.

    “Beware the young doctor and the old barber”: development and validation of a job age-type spectrum
    (Elsevier, 2021) Reeves, Michael Dennis; Fritzsche, Barbara Ann; Smith, Nicholas Anthony; Ng, Yin Lu; Department of Business Administration; Department of Business Administration; Marcus, Justin; Faculty Member; College of Administrative Sciences and Economics; 124653
    Taking a worker-centric approach, with evidence based on the experiences of working individuals, the current study examines the age-related stereotypes of jobs, the characteristics of age-stereotyped jobs, and the consequences of occupying them. In Study 1, we utilize samples of working adults from the US, Turkey, and Malaysia to establish validation evidence for a spectrum of 160 jobs (n = 123 raters per job). Study 1 findings indicate that entry-level jobs and jobs requiring manual labor or the use of technology are younger-typed, whereas senior level jobs and jobs requiring large investments in training or education are older-typed. The age-typing of jobs was found to be similar across countries for the vast majority of jobs. We then provide criterion validity evidence in Study 2, by testing the interactive effects of chronological age, job age-type, and sex on psychological age and perceived age and sex discrimination across samples of workers from these same three countries (n = 1469). Results upheld theoretical predictions based upon career timetables theory, prototype matching theory, and intersectional salience of ageism theory. The interactive effects of chronological age and job age-type were stronger for women than for men; the hypothesized patterns of effects were overall consistent for women but not for men.

    “Doing What Matters in Times of Stress” to decrease psychological distress during Covid-19: a rammed controlled pilot trial
    (Wolters Kluwer Medknow Publications, 2022) Uygun, Ersin; Karaoğlan Kahiloğulları, Akfer; Department of Psychology; Department of Psychology; N/A; Department of Psychology; Acartürk, Ceren; Kurt, Gülşah; İlkkurşun, Zeynep; Faculty Member; Teaching Faculty; Master Student; College of Social Sciences and Humanities; College of Social Sciences and Humanities; Graduate School of Social Sciences and Humanities; 39271; 368619; N/A
    Despite the increasing psychological distress during Covid-19, utilisation of face-to-face psychological interventions decreased profoundly. The aim of this study involving two parallel, two-armed pilot randomised controlled trials was to examine the effectiveness of a guided self-help intervention "Doing What Matters in Times of Stress" (DWM) in decreasing psychological distress in Turkish and Syrian participants. Seventy-four Turkish nationals and 50 Syrian refugee adults with psychological distress were randomly allocated to a DWM group or wait-list control group. The primary outcome measure was the Patient Health Questionnaire 9 postintervention. Secondary outcome measures were the Generalised Anxiety Disorder Scale, posttraumatic stress disorder (PTSD) Checklist for DSM-5, Generalized Self-Efficacy Scale and Acceptance and Action Questionnaire-II postintervention. Although this study was not powered to detect a significant effect for DWM postassessment between DWM and the control group, results showed a significant improvement in depression symptoms among Turkish participants in the DWM group (d = 0.46) and in PTSD symptoms among Syrian participants in the DWM group (d = 0.67) from pre- to postintervention assessment. These results indicate the potential of DWM to decrease mental health problems during the pandemic and importance of a fully powered, definitive controlled trial to examine its effectiveness both for the host community and refugees to reduce psychological distress during Covid-19.

    Objective: Meal management in Type 1 Diabetes (T1D) has barriers such as miscalculation of doses, insuffi- cient carbohydrate counting and numeracy skills. "My Friend Diabetes Carbohydrate Bolus Calculator" mobile app was developed as a hybrid version of nutrition apps and insulin titration apps to calculate meal's carbs and the matching bolus dose. This study investigates facilitator role of the app on lives of people with T1D. Materials and methods: People with T1D or their car-egivers were recruited from children diabetes foun-dation social media accounts, and they answered an online survey which examines the effects of the app on carbohydrate counting, diabetes management, and the usability of the app with 17 Likert-type questions (5-point). Descriptive and non-parametric tests were performed to analyze responses.Results: Of the 165 people who completed the survey, 58 (35.2%) had T1D, 107 (64.8%) had relatives with T1D; 87 (52.7%) participants were female, the mean age was 13.1 +/- 8.9 years, and the mean duration of dia-betes was 4.72 years. Of the participants, 130 used the app and agreed that the app improved the users' meal management, diabetes management, carbohydrate, and dose calculations (Mean score = 4.38 +/- 0.57). They were more confident in the dose calculation, freer in the food choices, and more confident in diabetes care because of the app (Mean score = 4.46 +/- 0.57). Conclusions: ''My Friend Diabetes Carbohydrate-Bolus Calculator" mobile app improved T1D management. Diabetes teams can reach more people through mobile apps and improve their clinical outcomes.

    “No worries, there is no error-free leadership!”: error strain, worries about leadership, and leadership career intentions among non-leaders
    (Stockholm University Press, 2022) Auvinen, E.; Tsupari, H.; Herttalampi, M.; Feldt, T.; Department of Psychology; Department of Psychology; Aycan, Zeynep; Faculty Member; College of Social Sciences and Humanities; 5798
    The growing body of research suggests that leadership is not among the most attractive career goals, especially for the younger work force. However, the need for leadership has not diminished. To shed light on the “problem of supply”, this study addresses the question of why high-potential individuals (i.e., non-leaders) do not pursue leadership positions by focusing on worries about leadership (WAL) and error-related strain. We had two aims: (1) to identify different profiles of WAL among highly educated professionals, and (2) to explore whether their error strain and leadership career intentions differ among the identified WAL profiles. Data were gathered from 955 highly educated Finnish employees representing different sectors. WAL was measured by a three-dimensional scale consisting of worries about failure, work-life imbalance, and harming others. Based on the Latent Profile Analysis, six WAL profiles emerged: (1) Average-WAL (37% of respondents), (2) Low-WAL (34%), (3) High-WAL (6%), (4) Failure-sensitive (9%), (5) Imbalance-sensitive (4%) and (6) Harm-sensitive (11%). Professionals in the Low-WAL profile reported the lowest error strain, whereas employees in the profiles of High-WAL and Failure-sensitive reported the highest error strain. Employees in the Low-WALprofile were more willing to pursue a leadership career in an unfamiliar organization compared to employees in other profiles. In addition, employees within the Low-WAL profile were more willing to pursue a leadership career in an unfamiliar organization compared to their home organization. Implications of our findings and future directions are discussed.

    “Noise Factory”: a qualitative study exploring healthcare providers’ perceptions of noise in the intensive care unit
    (Elsevier, 2020) Güner, Perihan; Kebapçı, Ayda; Faculty Member; School of Nursing; 203808
    Objectives: this study aimed to explore healthcare providers’ perceptions of noise in the intensive care unit. Design: a qualitative exploratory study was conducted using group interviews. Setting: the setting comprised a total of 15 participants (five physicians and ten registered nurses) working in an 18-bed medical surgical intensive care unit at a teaching hospital in Istanbul, Turkey. Semi-structured questions were formulated and used in focus group interviews, after which the recorded interviews were transcribed by the researchers. Thematic analysis was used to identify significant statements and initial codes. Findings: four themes were identified: the meaning of noise, sources of noise, effects of noise and prevention and management of noise. It was found that noise was an inevitable feature of the intensive care unit. The most common sources of noise were human-induced. It was also determined that device-induced noise, such as alarms, did not produce a lot of noise; however, when staff were late in responding, the sound transformed into noise. Furthermore, it was observed that efforts to decrease noise levels taken by staff had only a momentary effect, changing nothing in the long term because the entire team failed to implement any initiatives consistently. The majority of nurses stated that they were now becoming insensitive to the noise due to the constant exposure to device-induced noise. Conclusion: the data obtained from this study showed that especially human-induced noise threatened healthcare providers’ cognitive task functions, concentration and job performance, impaired communication and negatively affected patient safety. In addition, it was determined that any precautions taken to reduce noise were not fully effective. A team approach should be used in managing noise in intensive care units with better awareness.

    “O/F shift” in hybrid rockets
    (American Institute of Aeronautics and Astronautics, 2014) Toson, Elena; Evans, Brian; Department of Mechanical Engineering; Department of Mechanical Engineering; Karabeyoğlu, Mustafa Arif; Faculty Member; College of Engineering; 114595
    For most hybrid rocket systems, oxidizer to fuel ratio (O/F) changes over time due to 1) natural growth of the fuel port diameter and 2) oxidizer flow rate variations, if throttling is employed. This phenomenon, which is referred to as “O/F shift”, leads to a reduction in motor performance. Note that liquid or solid rocket motors are not subject to temporal O/F variations, which is wrongfully considered as one of the most critical disadvantages of hybrid rockets. In this paper, the effect of “O/F shift” is quantified for hybrid rocket motors. Analytical formulas for the temporal O/F variation and the overall c* efficiency drop associated with the variation has been derived for single circular port motors. It has been shown that for a typical motor, c* efficiency drop due to O/F variation is well below 0.2%, a value which is too small to be measured in an actual motor test. It is also shown that for a wagon wheel type multiport configuration (with triangular ports), efficiency drop is significantly worse than the single circular port case. Even for the multiport systems, the shift does not have a controlling effect on the overall efficiency of the motor. A number of strategies have been outlined to control the adverse effects of O/F variation in a hybrid rocket. For a single circular port design with limited throttling, no mitigation is required. For systems with deep throttling requirements, aft oxidizer injection seems like a viable strategy to retain a high level of overall efficiency.
