Inclusive Leadership and Employee Involvement in Creative Tasks in the Workplace: The Mediating Role of Psychological Safety

Abstract: This study examines how inclusive leadership (manifested by openness, accessibility, and availability of a leader) fosters employee creativity in the workplace. Using a sample of 150 employees, we investigated the relationship between inclusive leadership (measured at Time 1), psychological safety, and employee involvement in creative work tasks (measured at Time 2). The results of structural equation modeling (SEM) analysis indicate that inclusive leadership is positively related to psychological safety, which, in turn, engenders employee involvement in creative work.

Attachment working models and the sense of trust : An exploration of interaction goals and affect regulation

Abstract: Five studies examined the association between adult attachment style and the sense of trust in close relationships. Study 1 focused on the accessibility of trust-related memories. Studies 2-5 focused on trust-related goals and coping strategies, while using different data collection techniques (openended probes, diary methodology, lexical decision task). Findings showed that secure persons felt more trust toward partners, showed higher accessibility of positive trust-related memories, reported more positive trust episodes over a 3-week period, and adopted more constructive strategies in coping with the violation of trust than insecure persons. In addition, whereas intimacy attainment was the main trust-related goal for all the attachment groups, security attainment was an additional goal of anxious-ambivalent persons, and control attainment was an additional goal of avoidant persons. Findings are discussed in terms of attachment working models.

Attachment theory and emotions in close relationships: Exploring the attachment-related dynamics of emotional reactions to relational events

Abstract: Attachment theory is a powerful framework for understanding affect regulation. In this article, we examine the role played by attachment orientation in shaping emotional reactions to interpersonal transactions within close relationships. Using our recent integrative model of attachment-system activation and dynamics as a guide (M. Mikulincer & P. R. Shaver, 2003), we review relevant evidence, present new findings, and propose hypotheses concerning how people with different attachment styles are likely to react emotionally to relational events. Specifically, we focus on attachment-related variations in the emotional states elicited by a relationship partner’s positive and negative behaviors and by signals of a partner’s (relationship relevant or relationship irrelevant) distress or pleasure. In so doing, we organize existing knowledge and point the way to future research on attachment-related emotions in close relationships.

Review: a cognitive-affective model of organizational communication for designing IT

Abstract: There are several theories available to describe how managers choose a medium for communication. However, current technology can affect not only how we communicate but also what we communicate. As a result, the issue for designers of communication support systems has become broader: how should technology be designed to make communication more effective by changing the medium and the attributes of the message itself? The answer to this question requires a shift from current preoccupations with the medium of communication to a view that assesses the balance between medium and message form. There is also a need to look more closely at the process of communication in order to identify more precisely any potential areas of computer support. This paper provides the spadework for a new model of organizational communication, and uses it to review existing research, as well as to suggest directions for future research and development. Beginning with the crucial aspects of action, relationship, and choice, an integrated model of how people communicate is developed. This model incorporates three basic factors: (1) inputs to the communication process (task, sender-receiver distance, and values and norms of communication with a particular emphasis on inter-cultural communication); (2) a cognitive-affective process of communication; and (3) the communication impact on action and relationship. The glue that bonds these factors together is a set of communication strategies aimed at reducing the complexity of communication. The model provides a balance between relationship and action, between cognition and affect, and between message and medium. Such a balance has been lacking in previous work, and we believe it reflects a more realistic picture of communication behavior in organizations. A set of propositions generated from the model sets an agenda for studying the communication process as well as its inputs and outputs. Furthermore, this knowledge of the mechanisms that guide behavior is used to demonstrate the potential for developing design principles for future communication support systems.

GW190412: Observation of a binary-black-hole coalescence with asymmetric masses

Abstract: We report the observation of gravitational waves from a binary-black-hole coalescence during the first two weeks of LIGO’s and Virgo’s third observing run. The signal was recorded on April 12, 2019 at 05∶30∶44 UTC with a network signal-to-noise ratio of 19. The binary is different from observations during the first two observing runs most notably due to its asymmetric masses: a ∼30 M⊙ black hole merged with a ∼8 M⊙ black hole companion. The more massive black hole rotated with a dimensionless spin magnitude between 0.22 and 0.60 (90% probability). Asymmetric systems are predicted to emit gravitational waves with stronger contributions from higher multipoles, and indeed we find strong evidence for gravitational radiation beyond the leading quadrupolar order in the observed signal. A suite of tests performed on GW190412 indicates consistency with Einstein’s general theory of relativity. While the mass ratio of this system differs from all previous detections, we show that it is consistent with the population model of stellar binary black holes inferred from the first two observing runs.
