This paper aims to investigate the deposited structure and mechanical performance of printed materials obtained during initial development of the Big Area Additive Manufacturing (BAAM) system at Oak Ridge National Laboratory. Issues unique to large-scale polymer deposition are identified and presented to reduce the learning curve for the development of similar systems.
Although the BAAM’s individual extruded bead is 10-20× larger (∼9 mm) than the typical small-scale systems, the overall characteristics of the deposited material are very similar. This study relates the structure of BAAM materials to the material composition, deposition parameters and resulting mechanical performance.
Materials investigated during initial trials are suitable for stiffness-limited applications. The strength of printed materials can be significantly reduced by voids and imperfect fusion between layers. Deposited material was found to have voids between adjacent beads and micro-porosity within a given bead. Failure generally occurs at interfaces between adjacent beads and successive layers, indicating imperfect contact area and polymer fusion.
The incorporation of second-phase reinforcement in printed materials can significantly improve stiffness but can result in notable anisotropy that needs to be accounted for in the design of BAAM-printed structures.
This initial evaluation of BAAM-deposited structures and mechanical performance will guide the current research effort for improving interlaminar strength and process control.

The purpose of this study was to examine the mediating role of appraisals in three stressor–well-being relationships: (1) the mediating role of challenge appraisals in the relationship between daily skill demands and daily work engagement, (2) the mediating role of hindrance appraisals in the relationship between daily interruptions and daily depletion and (3) the mediating role of threat appraisals in the relationship between daily emotional demands and daily anxiety. We also examined the moderating influence of conscientiousness on the daily skill demands–challenge appraisal relationship, the moderating role of extraversion on the daily interruptions–hindrance appraisal relationship and the moderating influence of neuroticism on the daily emotional demands–threat appraisal relationship. Supplemental analyses also examined the moderating influence of the aforementioned personality traits on the respective direct effects of stressors on well-being outcomes.
We tested our hypotheses using a 5-days experience sampling design in a sample of 114 working adults and employed multilevel modeling.
All hypothesized mediating mechanisms were supported, however, the majority of moderation hypotheses were not supported.
We sought to extend the relatively recent advancement in the challenge–hindrance framework to provide additional evidence of the utility of distinguishing between challenge, hindrance and threat stressors. Although not supported, this is the one of the first papers to test the moderating influence of personality traits on the stressor–appraisal relationship.

The purpose of this paper is to present an empirical analysis of the European Central Bank (ECB) deposit rate dynamics during 2014–2020, attempting to answer how deep could be cut further this rate without causing persistent yield curve inversions (YCI), i.e. lower yields for longer terms. It addresses the sustainability of the traditional banking and shows that inverted yield curves would require changing the banking-as-usual model to the government-guaranteed long-term-borrowing coupled with short-term-lending. This research poses the question of whether the banking sector should become a public utility.
The future scenarios of negative interest rate (NIR) behavior are modeled seeking to increase the understanding of NIR environment. Using an event-study design, empirical analyses of the ECB deposit rate cuts on the Euro Over-Night Index Average rates is performed at different maturities.
This study finds that, starting from the lower limit of 80 basis points below zero, the ECB deposit rate is likely to result in complete YCIs.
This paper evidences that moving rates into a more negative territory is likely to be completely counterproductive for banking industry, implying that banking at such conditions would become heavily dependent on governmental support. The results shed light on the interdependence of the banking business, financial monetary policy and welfare of the society, providing policymakers with empirically defined milestones for policy implementations.
This paper clarifies the impact of the ECB deposit rate on the overall shape of yield curves. The novelty of this research resides in investigation of YCI by simulating NIR dynamics.

Global mindset is an important theme in the international business strategy and organizational behavior literatures. However, these different paradigms define and operationalize global mindset in disparate ways, which creates problems for conducting empirical research as the disparity hampers the development of testable models. This article seeks to unify the different paradigms by introducing a third perspective from cognitive psychology that clarifies the process of mindset activation. We apply a process model of mindset activation to global mindset to build a theory of mindset switching relevant for global leaders. We operationalize global mindset as a dynamic process of mindset switching and suggest that the most appropriate mindset for a situation can be primed to activate. We also propose cosmopolitanism and cognitive complexity as antecedents to appropriate mindset activation and mindset switching. Finally, we suggest that mindset/situation congruence results in global leader creativity and boundary spanning. By applying the cognitive psychology literature to global mindset research, we clarify the process of global mindset and why it is important for leaders to understand how different primes might activate the most appropriate mindset. Our model provides a means for managers to become more cognitively aware of how they problem solve in a highly complex and multilayered world. This paper proposes a unique, dynamic model that captures dualities of global leadership. The model provides a new perspective of global mindset that is testable with existing measures and procedures.

One of the biggest challenges facing global organizations is the ability of leadership and International Human Resource Management (IHRM) professionals to capture the positive outcomes of a diverse workforce while fostering inclusion amongst its workers. New theory based upon optimal distinctiveness theory has challenged researchers to approach inclusion in a holistic manner, transcending political boundaries and cultural meanings of diversity to instead promote the uniqueness of individuals within-group belongingness. This chapter proposes a theoretical model that suggests leader capabilities such as global mindset can foster inclusiveness while reaping the benefits of unique backgrounds and diverse ideas. Two important individual-level outcomes of inclusiveness are presented: creativity and psychological safety. Also discussed are implications for strategic IHRM through recruitment, selection, talent management, and performance management activities.

The purpose of this paper is to identify the antecedents of the transformational learning process associated with early international experiences. Secondarily, this research aimed to explain how the antecedent “transformational triggers” may contribute to developing intercultural competencies.
A qualitative study was conducted using open-ended survey response data regarding the transformational triggers that occurred during a study abroad program. The data were collected from a sample of 82 participants from a Midwestern university in the USA.
Four categories of transformational triggers were identified: immersing with local customs and people, experiencing the novelty of “normality,” communicating in a new language, and finding time for self-reflection.
For a qualitative study, the sample size was sufficient for exploring the types of transformational triggers associated with early international experiences. One limitation of this study is that the sample studied were undergraduate students, or young sojourners, experiencing early, and for some even their first, international experience. Future research can replicate the findings to confirm the same typology of transformational triggers exists for older managers during their early or first international assignment.
The transformational triggers identified from this study provide managers with an understanding of the type of experiences that are important to developing intercultural competencies. With these triggers, they can design global leader development programs or expatriate assignments to include time and tools to reflect and provide support specific to each type of transformational trigger.
This study offers the first field study of the transformational triggers associated with developing intercultural competencies from early international experiences.

The purpose of this paper is to discuss the concept of cultural psychological capital, its impact on motivational cultural intelligence (CQ), the influence of motivational cultural intelligence on metacognitive awareness, and the moderating role of perspective taking on the relationship between motivational cultural intelligence and metacognition.
Collected data from international management program alumni to test the hypotheses.
The results show that cultural psychological capital has a positive relationship with motivational cultural intelligence, which in turn relates to metacognitive awareness, and perspective taking does not moderate the relationship between motivational cultural intelligence and metacognition.
The data were collected from a single source. The study supports broaden-and-build theory (Fredrickson, 2001) by demonstrating that cultural psychological capital has an important association with motivational cultural intelligence.
Cultural psychological capital can be improved. Therefore, organizations that desire to increase the motivation of employees may consider improving the cultural psychological capital of employees. Learning is an important outcome of motivational cultural intelligence, and it is an asset for today's organizations.
The study takes a positive perspective for cross-cultural experiences and identifies cultural psychological capital as an important resource for expatriates. Metacognitive awareness, as an outcome, provides support that cross-cultural experience results in higher learning for individuals who are motivated.

The debate over how services should be advertised and communicated has raged on for decades. Much of the early work on services emphasized the use of tangible cues and was primarily issue and/or profession specific. There are no real communication guidelines that encompass all service marketers. This paper looks at how consumers use information in a purchase situation to establish communication guidelines for service providers. Marketers know consumers rarely have full information in a buying situation and have devised communication strategies accordingly. Services in particular offer less information than traditional consumer goods because of services inherent distinguishing characteristics, e.g. intangibility, non‐standardization and concurrent production and consumption. Integrating both conceptual and empirical work this paper uses a framework of incomplete information to examine commonly practiced communication methods of advertising, signaling, personal sources and relationship marketing. Using the two‐dimensional framework advanced in this paper, 16 communication guidelines for service providers are presented.
