Flooded with Information from Social Media: Effects of Disaster Information Source and Visuals on Viewers' Cognitive, Affective, and Behavioral Responses

While a variety of crisis types loom as real risks for organizations and communities, and the media landscape continues to evolve, research is needed to help explain and predict how people respond to various kinds of crisis and disaster information. For example, despite the rising prevalence of digital and mobile media centered on still and moving visuals, and stark increases in Americans’ use of visual-based platforms for seeking and sharing disaster information, relatively little is known about how the presence or absence of disaster visuals online might prompt or deter resilience-related feelings, thoughts, and/or behaviors. Yet, with such insights, governmental and other organizational entities as well as communities themselves may best help individuals and communities prepare for, cope with, and recover from adverse events. Thus, this work uses the theoretical lens of the social-mediated crisis communication model (SMCC) coupled with the limited capacity model of motivated mediated message processing (LC4MP) to explore effects of disaster information source and visuals on viewers’ resilience-related responses to an extreme flooding scenario. Results from two experiments are reported. First a preliminary 2 (disaster information source: organization/US National Weather Service vs. news media/USA Today) x 2 (disaster visuals: no visual podcast vs. moving visual video) factorial between-subjects online experiment with a convenience sample of university students probes effects of crisis source and visuals on a variety of cognitive, affective, and behavioral outcomes. A second between-subjects online experiment manipulating still and moving visual pace in online videos (no visual vs. still, slow-pace visual vs. still, medium-pace visual vs. still, fast-pace visual vs. moving, slow-pace visual vs. moving, medium-pace visual vs. moving, fast-pace visual) with a convenience sample recruited from Amazon’s Mechanical Turk (mTurk) similarly probes a variety of potentially resilience-related cognitive, affective, and behavioral outcomes. The role of biological sex as a quasi-experimental variable is also investigated in both studies. Various implications for community resilience and recommendations for risk and disaster communicators are explored. Implications for theory building and future research are also examined. Resulting modifications of the SMCC model (i.e., removing “message strategy” and adding the new category of “message content elements” under organizational considerations) are proposed.

THE INFLUENCE OF MOTIVATION ON EMOTION REGULATION AND MOTOR PERFORMANCE: EXAMINATION OF A NEURO-AFFECTIVE MODEL

Mental stress is known to disrupt the execution of motor performance and can lead to decrements in the quality of performance, however, individuals have shown significant differences regarding how fast and well they can perform a skilled task according to how well they can manage stress and emotion. The purpose of this study was to advance our understanding of how the brain modulates emotional reactivity under different motivational states to achieve differential performance in a target shooting task that requires precision visuomotor coordination. In order to study the interactions in emotion regulatory brain areas (i.e. the ventral striatum, amygdala, prefrontal cortex) and the autonomic nervous system, reward and punishment interventions were employed and the resulting behavioral and physiological responses contrasted to observe the changes in shooting performance (i.e. shooting accuracy and stability of aim) and neuro-cognitive processes (i.e. cognitive load and reserve) during the shooting task. Thirty-five participants, aged 18 to 38 years, from the Reserve Officers’ Training Corp (ROTC) at the University of Maryland were recruited to take 30 shots at a bullseye target in three different experimental conditions. In the reward condition, $1 was added to their total balance for every 10-point shot. In the punishment condition, $1 was deducted from their total balance if they did not hit the 10-point area. In the neutral condition, no money was added or deducted from their total balance. When in the reward condition, which was reportedly most enjoyable and least stressful of the conditions, heart rate variability was found to be positively related to shooting scores, inversely related to variability in shooting performance and positively related to alpha power (i.e. less activation) in the left temporal region. In the punishment (and most stressful) condition, an increase in sympathetic response (i.e. increased LF/HF ratio) was positively related to jerking movements as well as variability of placement (on the target) in the shots taken. This, coupled with error monitoring activity in the anterior cingulate cortex, suggests evaluation of self-efficacy might be driving arousal regulation, thus affecting shooting performance. Better performers showed variable, increasing high-alpha power in the temporal region during the aiming period towards taking the shot which could indicate an adaptive strategy of engagement. They also showed lower coherence during hit shots than missed shots which was coupled with reduced jerking movements and better precision and accuracy. Frontal asymmetry measures revealed possible influence of the prefrontal lobe in driving this effect in reward and neutral conditions. The possible interactions, reasons behind these findings and implications are discussed.

Psychological Ownership of Employees as a Mediator in the Justice - Affective Commitment Relationship

Numerous scholars have accumulated evidence on the positive effects that employees' organizational justice perceptions exert on work-related outcomes such as affective commitment. However, research still lacks understanding of the underlying mechanisms connecting the two constructs. In this article we aim to narrow this gap by examining the concept of psychological ownership as a possible mediator between organizational justice perceptions and affective commitment. Investigating a sample of 619 employees, we find distributive justice to be positively related to psychological ownership, and observe psychological ownership as a full mediator of the distributive justice and affective commitment relationship. These insights offer a new explanation in understanding the justice-commitment connection, contributing to both organizational justice and psychological ownership literature and opening up ways for promising future research

Les échecs de la mission canadienne en Afghanistan : déficits de sécurité humaine

La mission canadienne en Afghanistan constitue la plus longue intervention étrangère de l'histoire du pays et a été marquée par un effort important dans la province de Kandahar depuis 2006. Aujourd'hui, il s'avère que la mission à Kandahar présente des échecs importants. Afin d'appréhender la nature de ces échecs, ce travail propose des pistes de réflexions pour améliorer notre compréhension face à cet enjeu. Pour ce faire, le mémoire se questionne à savoir dans quelle mesure le Canada a-t-il respecté l'approche de sécurité humaine au sein de sa mission à Kandahar? La mission britannique dans la province de Helmand en Afghanistan est également utilisée comme outil de comparaison. En guise d'hypothèse, il est proposé que le Canada n'a pas respecté l'approche de sécurité humaine et que cela pourrait contribuer à la compréhension des échecs de la mission à Kandahar. D'abord, les bilans détaillés de ces missions sont présentés et il est démontré que la mission britannique a connu un meilleur bilan que la mission canadienne. Ensuite, à l'aide de la méthode de l'analyse de contenu et d'un codage, les missions canadiennes et britanniques sont analysées afin de déterminer leur correspondance respective face à l'approche de sécurité humaine. Les résultats démontrent que la mission britannique respecte l'approche de sécurité humaine de façon plus importante que la mission canadienne. Finalement, une analyse documentaire propose des pistes de réflexions afin de comprendre en quoi ce déficit de sécurité humaine pourrait permettre d'expliquer les échecs de cette mission lors de futures recherches. Ce mémoire apporte donc deux conclusions. D'abord, la mission canadienne n'a pas respecté l'approche de sécurité humaine malgré le fait que le Canada ait affirmé l'avoir fait. De plus, il est clair que le non-respect de l'approche de sécurité humaine constitue une avenue intéressante afin de comprendre les insuccès canadiens.

Off-line and On-line Affective Recognition of a Computer User through A Biosignal Processing Approach

Physiological signals, which are controlled by the autonomic nervous system (ANS), could be used to detect the affective state of computer users and therefore find applications in medicine and engineering. The Pupil Diameter (PD) seems to provide a strong indication of the affective state, as found by previous research, but it has not been investigated fully yet. In this study, new approaches based on monitoring and processing the PD signal for off-line and on-line affective assessment (“relaxation” vs. “stress”) are proposed. Wavelet denoising and Kalman filtering methods are first used to remove abrupt changes in the raw Pupil Diameter (PD) signal. Then three features (PDmean, PDmax and PDWalsh) are extracted from the preprocessed PD signal for the affective state classification. In order to select more relevant and reliable physiological data for further analysis, two types of data selection methods are applied, which are based on the paired t-test and subject self-evaluation, respectively. In addition, five different kinds of the classifiers are implemented on the selected data, which achieve average accuracies up to 86.43% and 87.20%, respectively. Finally, the receiver operating characteristic (ROC) curve is utilized to investigate the discriminating potential of each individual feature by evaluation of the area under the ROC curve, which reaches values above 0.90. For the on-line affective assessment, a hard threshold is implemented first in order to remove the eye blinks from the PD signal and then a moving average window is utilized to obtain the representative value PDr for every one-second time interval of PD. There are three main steps for the on-line affective assessment algorithm, which are preparation, feature-based decision voting and affective determination. The final results show that the accuracies are 72.30% and 73.55% for the data subsets, which were respectively chosen using two types of data selection methods (paired t-test and subject self-evaluation). In order to further analyze the efficiency of affective recognition through the PD signal, the Galvanic Skin Response (GSR) was also monitored and processed. The highest affective assessment classification rate obtained from GSR processing is only 63.57% (based on the off-line processing algorithm). The overall results confirm that the PD signal should be considered as one of the most powerful physiological signals to involve in future automated real-time affective recognition systems, especially for detecting the “relaxation” vs. “stress” states.

A study of employee affective organisational commitment and retention in Pakistan:the roles of psychological contract breach and norms of reciprocity

Social exchange theory and notions of reciprocity have long been assumed to explain the relationship between psychological contract breach and important employee outcomes. To date, however, there has been no explicit testing of these assumptions. This research, therefore, explores the mediating role of negative, generalized, and balanced reciprocity, in the relationships between psychological contract breach and employees’ affective organizational commitment and turnover intentions. A survey of 247 Pakistani employees of a large public university was analyzed using structural equation modeling and bootstrapping techniques, and provided excellent support for our model. As predicted, psychological contract breach was positively related to negative reciprocity norms and negatively related to generalized and balanced reciprocity norms. Negative and generalized (but not balanced) reciprocity were negatively and positively (respectively) related to employees’ affective organizational commitment and fully mediated the relationship between psychological contract breach and affective organizational commitment. Moreover, affective organizational commitment fully mediated the relationship between generalized and negative reciprocity and employees’ turnover intentions. Implications for theory and practice are discussed.

Young adults’ perceptions of and affective bonds to a rural tourism community

Many rural areas, in Sweden and worldwide, experience population decline where the young leave for education and work in urban areas. Employment has declined in several rural industries, such as agriculture, forestry, and fishing, while growing in other industries are often located in urban areas. Politicians and organizations have put much hope in tourism as a tool of rural development, but can tourism help reverse the rural out-migration trend among young adults? This paper explores how tourism affects young inhabitants’ perceptions of and affective bonds to a rural area in Sweden, the ski resort of Sälen. Students from the 1993–1995 elementary school graduating classes were interviewed about their migration history, childhood, and view of and ties to Sälen. The respondents experience that tourism contributes to a more vital community incorporating influences from elsewhere, but without eliminating the positive aspects of rural life. The regular flow of people – tourists, seasonal workers, and entrepreneurs – passing through Sälen presents opportunities to extend one’s social network that are widely appreciated by respondents. The high in and out mobility constitutes a key part of Sälen’s character. Contributions from tourism – such as employment, entertainment, leisure, and opportunities to forge new social relationships – are available during the adult transition, the life phase when rural areas are often perceived as least attractive. Even though out-migration occurs in Sälen, and some respondents still find Sälen too small, tourism has clearly increased the available opportunities and contributed significantly to making Sälen more attractive to young adults.

Sécurité d’attachement mère-enfant et qualité de la relation élève-enseignant : liens spécifiques et effets modérateurs du niveau de risque psychosocial et du sexe de l’enfant

Cette étude vise à examiner les liens entre la sécurité d’attachement mère-enfant et les trois dimensions de la relation élève-enseignant, soit la proximité, la dépendance et les conflits. Plus encore, elle vise à examiner si les relations entre ces deux construits sont influencées ou modérées par le sexe de l’enfant et le niveau risque psychosocial auquel l’enfant est exposé. Quatre-vingt-neuf (89) dyades mère-enfant ont été évaluées. La sécurité d’attachement est mesurée à domicile lorsque l’enfant est âgé de 15 et de 18 mois et également en laboratoire deux semaines après la visite à domicile. De manière à évaluer la qualité de la relation élève-enseignant, les enseignantes des enfants ont été sollicitées vers la fin de la première année scolaire (environ 7 ans) afin de compléter un questionnaire. Dans un premier temps, les résultats obtenus suggèrent que les liens significatifs entre nos deux concepts sont spécifiques à seulement certaines dimensions de la relation élève-enseignant. De plus, les résultats montrent un effet de modération entre la sécurité d’attachement et le niveau de risque psychosocial dans la prédiction de la qualité de la relation élève-enseignant, plus spécifiquement au niveau des conflits. Quant au sexe de l’enfant, aucun effet significatif n’est trouvé sur la relation entre les deux concepts.

Étude des propriétés psychométriques de l’échelle affective du Questionnaire de maturité vocationnelle

Les conseillers d’orientation (c.o.) en milieu scolaire ont plusieurs rôles à remplir auprès des élèves, entre autres la réponse aux demandes des élèves, le maintien de l’accès à une documentation pertinente et l’accompagnement dans une meilleure connaissance de soi et du monde du travail (Dupont, Gingras et Marceau, 2002a). Pour ce faire, plusieurs moyens sont à leur disposition, dont l’évaluation psychométrique (OCCOQ, 2013). Un concept qui pourrait utile de mesurer auprès des adolescents est la maturité vocationnelle (Jordaan et Heyde, 1979). Des instruments de mesure évaluant la maturité vocationnelle existent déjà, mais aucun d’entre eux ne semble convenir parfaitement à la réalité du Québec, emmenant la création d’un nouvel outil, le Questionnaire de maturité vocationnelle (QMV). L’objectif de ce mémoire est de vérifier les propriétés psychométriques de l’échelle affective du QMV. Les participants de l’étude sont 1 164 adolescents québécois âgés entre 14 et 18 ans (moyenne : 15,30 ans), provenant de 14 écoles secondaires. Pour ce qui est du niveau scolaire des participants, 511 (43,9 %) sont en 3e secondaire, 303 (26 %) sont en 4e secondaire et 350 (30,1 %) sont en 5e secondaire. Les résultats obtenus appuient la fidélité et la validité de l’instrument de mesure.

Emotions in the Experiential Consumption of Mobile Phones

Although marketers have a strong interest in finding ways to engage with consumers through mobile phones, the everyday experiential, or affective consumption practices surrounding this technology have received limited attention in the literature. To address this limitation, we used appraisal theory, which specifies it is the way individuals appraise situations or events that elicit emotions. We conducted an experience sampling method study to explore the emotions that individuals experience during their interactions with and through their mobile phones and what situations or events elicit these emotions. The preliminary findings show a number of significant relationships between emotions and specfic clusters of situations and events. Additionally, age and gender were also important indicators. The research contributes to a deeper understanding of the experiential nature of mobile information technologies through consumers’ everyday-consumption-related emotions and the situations and events that elicit them.
