Distrustful Complacency and the COVID-19 Vaccine: How Concern and Political Trust Interact to Affect Vaccine Hesitancy

We test the hypothesis that COVID-19 vaccine hesitancy is attributable to distrustful complacency—an interactive combination of low concern and low trust. Across two studies, 9,695 respondents from different parts of Britain reported their level of concern about COVID-19, trust in the UK government, and intention to accept or refuse the vaccine. Multilevel regression analysis, controlling for geographic area and relevant demographics, confirmed the predicted interactive effect of concern and trust. Across studies, respondents with both low trust and low concern were 10%–22% more vaccine hesitant than respondents with either high trust or high concern, and 26%–29% more hesitant than respondents with both high trust and high concern. Results hold equally among White, Black, and Muslim respondents, consistent with the view that regardless of mean-level differences, a common process underlies vaccine hesitancy, underlining the importance of tackling distrustful complacency both generally and specifically among unvaccinated individuals and populations.     

Does survival context enhance memory for source? A within-subjects comparison

ABSTRACT

Nairne, Thompson, and Pandeirada [2007. Adaptive memory: Survival processing enhances retention. Journal of Experimental Psychology: Learning, Memory, and Cognition, 33, 263–273] demonstrated that processing words according to their relevance to a survival scenario enhanced their subsequent retrieval in recall and recognition tasks compared to a variety of control scenarios. From an adaptive perspective, it is maintained that processing words in a survival context should also enhance memory for source; however, evidence in the literature is rather mixed regarding a survival context advantage for source memory. In the current study, we conducted four experiments to systematically investigate the survival advantage in source memory, when the context itself is the source, with both recall (Experiments 1A and 1B) and recognition tests (Experiments 2A and 2B). Results showed a survival advantage for item memory over the control contexts in all experiments. The survival context advantage was not extended to source memory performance in Experiment 1A. Results from all other experiments, however, indicated a survival context advantage for both item and source memory. Findings are discussed in relation to possible proximate mechanisms underlying the survival processing effect.     

Lebanese Muslim Views of September 11

This research note aimed at empirically assessing Lebanese Muslim views of the September 11 attacks. We proposed that young age and political Islam served as significant determinants of support for the attacks. Although we proposed that Sunni Muslim respondents would manifest more support for the attacks than Shi'is, we advanced that socioeconomic conditions should not affect the views of the respondents. The data came from a stratified random sample, consisting of 337 male and female Sunni and Shi'i respondents, conducted in the Greater Beirut area during the months of October and November 2001. The findings sustained the hypotheses that age and political Islam determined approval of the attacks, as well as the hypothesis that socioeconomic conditions did not predict the respondents' views. The results did not sustain the hypothesis that Sunni respondents exceeded Shi'is in their display of support for the attacks.     

A comparative study of Sr-doped LaMnO3 synthesised via solid-state reaction and sol–gel methods

ABSTRACT

This work deals with the synthesis of hole-doped La_1-xSr_xMnO₃ (x?=?0.25 and 0.33) perovskite via two different ways, namely a solid-state reaction method and a sol–gel process. Various properties of the samples have been investigated and compared by means of different techniques, namely X-ray diffraction (XRD), temperature-dependent resistivity measurements in the temperature range 25–300?K using a closed cycle refrigerator and vibrating sample magnetometry (VSM). All samples have orthorhombic crystal symmetry and an irregular variation in unit-cell volume with increase in Sr content. The average crystallite size was determined from the XRD data and found to lie in the range 19–22?nm. Metal–insulator transitions (MIT) were observed in all the samples via low-temperature electrical characterisations. The magnetic measurements confirm that the magnetisation does not saturate for the 25% Sr doped samples up to the available field of 10?kOe. The magnetic response also supports the interpretation of XRD and resistivity data. The obtained results are explained on the basis of double-exchange and super-exchange mechanisms.     

Investigating the Role of the Big Five on the Social Loafing of Information Technology Workers1

The main purpose of the study was to investigate the role of Big Five personality dimensions (Extraversion, Conscientiousness, Openness to Experience, Neuroticism, and Agreeableness) on social loafing (SL) in a field setting. Data were gathered from both employees and their supervisors working in three leading software companies in Ankara, Turkey. The study was conducted in two phases. In the pilot study, SL and perceived coworker SL scales were developed. The task visibility scale was adapted to Turkish. The internal consistency reliabilities of the scales were tested using a pilot study with a sample of employees. In the main study, hypotheses were tested by gathering data from 156 participants and their 33 supervisors. Results supported only the two hypotheses proposing positive relations between extraversion and SL and between neuroticism and SL. The results are discussed along with practical implications, limitations of the study, and future directions.     

Mother–Child Relationships Following a Disaster: The Experiences of Turkish Mothers Living in a Container City After the 2011 Van Earthquake

In this qualitative study, informed by ethnography and phenomenology, we aimed to explore the impact of mass trauma on mother–child relationships. Specifically, affected relational processes that might interrupt healthy parenting practices and child behavioral and emotional outcomes were explored. Fifteen Turkish mothers exposed to a massive earthquake in 2011 and relocated to a container city in the Van province, Turkey, were interviewed for this study in 2013. Data analysis was informed by elements of Spradley’s Developmental Research Sequence (DRS) and interpretive phenomenological analysis. Findings indicated that psychological trauma resulting from the earthquake and consequent displacement disrupted and exacerbated mothers’ ability to cope with distress. This, in turn, influenced mothers’ ability to manage their negative emotions and resulted in more yelling, beatings, and higher aggression towards their children as well as a lack of positive emotional and physical engagement. Mothers perceived their own struggles as increasing their children’s disruptive behaviors, such as being less compliant, becoming emotionally distant and modeling mothers’ negative behaviors. The counseling mothers received at the local mental health center supported mothers in building greater physical and emotional connection with their children, regulating their negative emotions and gaining effective parenting skills to discipline their children. The current study represents a preliminary step towards understanding parenting experiences of Turkish mothers in mass trauma contexts.     

Posttraumatic Stress and Depression Reactions Among Survivors of the Istanbul November 2003 Terrorist Attacks

This study investigated posttraumatic stress and depression reactions among survivors of the Istanbul November 2003 terrorist bombings that destroyed synagogues, an HSBC bank, and the British General Consulate. One hundred and forty-nine survivors completed a questionnaire measuring exposure, current posttraumatic stress, and depression responses 6 months after the blasts. This study showed that the prevalence rate of posttraumatic stress disorder (PTSD) among survivors was 35.6%?and the rate of depression was 23.5%. PTSD was strongly predicted by perceived life threat, whereas depression was strongly predicted by death of a close friend. Overall, female survivors were found to be more vulnerable to developing posttraumatic stress as well as depression after the terrorist bombings.     

Working in the hangar: The impact of psychological capital on work outcomes among army aircraft mechanics

Based on positive organizational behavior, this study aimed to explore the impact of psychological capital (PsyCap) on task performance, organizational citizenship behaviors, affective commitment, and job satisfaction among army aircraft mechanics. Data was obtained from 260 aircraft mechanics working in various Turkish Army aviation units. The hypotheses were tested using a series of hierarchical regressions. The results indicated that those with higher PsyCap are more likely to depict task performance, engage in highly extra-role behaviors, be more committed to their organizations, and be highly satisfied with their jobs that are advantageous to army aviation settings. The authors concluded that promoting the levels of PsyCap could be effective in elevating aircraft mechanics’ work attitudes and behaviors. Military aviation units are encouraged to establish human resource development programs to foster the PsyCap of their soldiers, which in turn, enhances crucial work attitudes.     

Influence of Zn incorporation on the microstructural and magnetic properties of La0.67Sr0.33Mn1−xZnxO3 nanoparticles synthesised by the sol–gel method

Perovskite manganite nanoparticles with the chemical formula La_0.67Sr_0.33Mn_1?xZn_xO₃ (x = 0, 0.1 and 0.2) were prepared by the sol–gel process and the influence of Zn substitution on their microstructural and magnetic properties studied in detail. X-ray diffractometry (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were employed for crystal structure determination and microstructural analysis. The results of XRD analysis confirmed the polycrystalline nature and rhombohedral crystal structure with space group R(-3c) for all compositions. SEM micrographs of the samples revealed an agglomeration/well-connected appearance of the particles. The composition and uniform distribution of all the elements were established by energy-dispersive spectroscopy. TEM images clearly confirmed an almost spherical shape of the nanoparticles with an average particle size of about 11, 14 and 13 nm for the 0, 10 and 20% Zn-doped samples, respectively. The magnetic behaviour of the nanoparticles was studied at room temperature with a vibrating sample magnetometer (VSM) up to a field of 1.8 Tesla. These measurements established a superparamagnetic nature with a variation in the saturation magnetization (M_s) with Zn content.
