Globalization has necessitated cross-cultural communication among groups and individuals alike, often beginning with management. This project considers how the degree of Power Distance, one of Hofstede's cultural dimensions, may change over time as a result of exposure to different, and often opposing, cultural values. We conducted two surveys 12 weeks apart collecting an initial sample of 317 and retaining a secondary sample of 142. We gathered data on demographics, education, on-campus involvement, cultural dimensions, and levels of comfort with different cultures. Through data analysis we found that as a result of exposure to different cultural values, cultural groups adjust their own views on Power Distance. Specifically, we found that the Anglo cultural group and the international cultural subgroup that had been living in the U.S. for less than 10 years trended towards each other on levels of Power Distance. We also found that international female students adjusted to new cultural surroundings faster than their male counterparts. These discoveries have led us to conclusions regarding the influence of awareness of other cultural values through international exposure, specifically that of Power Distance, as well as male versus female differences in cultural adjustment, and how differing views might trend towards each other with recurrent interaction.

Description
Research suggests that behaving in an ingratiatory manner towards one’s supervisor is a double-edged sword. On the one hand, ingratiation is a powerful tool through which employees develop positive social exchange relationships with target audiences (i.e., supervisors) and subsequently obtain desired outcomes at work. On the other hand, third party observers of ingratiation often view this behavior (and the people enacting it) in a negative manner, thereby hindering ingratiatory employees’ ability to develop high quality social exchange relationships with these individuals. However, this research primarily focuses on how organizational actors perceive of ingratiatory employees while neglecting the social context in which this behavior occurs. This is an important limitation because there are compelling reasons to believe that the social context plays a crucial role in how individuals react to ingratiation. Specifically, the social context may influence the extent to which ingratiation is salient, valued, and/or perceived as normative behavior by organizational members both within and external to the ingratiator-target dyad, which in turn affects how this behavior relates to relationship quality with the target and observers. The objective of my dissertation is to address this limitation by integrating a social context perspective with social exchange theory to build a “frog-pond” model of ingratiation. To that end, I propose that employees’ ingratiation relative to their team members, rather than absolute levels of ingratiation, drives positive exchange quality with supervisors. Furthermore, I hypothesize that congruence between the focal employee’s ingratiation and other team members’ ingratiation increases employees’ social exchange quality with team members. I also shed light on the asymmetrical nature of ingratiation (in)congruence by investigating how different types of congruence and incongruence impact social exchange quality with team members in different ways. In addition, I examine how relative ingratiation indirectly influences supervisors’ citizenship behavior toward the focal employee via focal employee-supervisor social exchange quality, as well as how ingratiation congruence indirectly affects team members’ citizenship behavior toward the focal employee through social exchange quality between the two parties. I test my hypotheses in a multi-wave multi-source field study of 222 employees and 64 teams/supervisors.

Description
I develop and test theoretical hypotheses for how employees' authenticity at work influences their motivational, relational, and effectiveness outcomes. These hypotheses are grounded in the idea that when individuals feel they display their true selves at work, they can more fully employ their physical, cognitive and emotional energies in their work roles, which in turn leads to higher levels of employee effectiveness (e.g., task performance, perceived value to the organization, and promotability). In addition to this personal motivational process, individuals who are more authentic also develop high-quality relationships with their coworkers, thereby receiving more instrumental support and minimizing the antagonistic encounters they have with their colleagues. Both types of coworker interactions should, in turn, also influence the focal individual's effectiveness at work. Finally, I hypothesize that the relationships between authenticity and these relational and effectiveness outcomes are moderated by certain personality traits, such that when an individual is highly narcissistic, has very low self-esteem, or has strongly held values or beliefs generally perceived to be negative or deviant, the relationships change: authenticity's positive influence on coworker instrumental support becomes less positive, and authenticity's negative influence on coworker incivility becomes less negative. These moderation effects are expected for employee effectiveness as well. The sample used to test these hypotheses consisted of 102 employees and their 16 supervisors from two private companies headquartered in the Southwest United States. Authenticity was found to be positively associated with employee engagement, coworker instrumental support, and employee effectiveness, and negatively associated with coworker incivility. Once other factors were controlled for, significant relationships remained with employee engagement and coworker support. Contrary to expectations, neither engagement nor coworker interactions mediated the authenticity-employee effectiveness relationship. A dark side of authenticity was found for two of the three personality traits: self-esteem moderated the relationship between authenticity and coworker instrumental support, such that when self-esteem was low, the relationship between authenticity and coworker support was significantly weaker. Additionally, narcissism moderated the relationship between authenticity and employee effectiveness such that when narcissism was low, the relationship between authenticity and effectiveness was positive, but when narcissism was high, the relationship became negative.

Description
Accountability has been commonly referred to in the literature as a person’s expectation about others’ evaluations. However, in this study, I develop an alternative perspective of leader accountability by defining it as an individual’s degree of ownership regarding good or poor performance and acceptance of associated rewards or disciplinary actions. Based on attribution theory, leaders can have internal and external ownership regarding good and poor performance. I propose that accountability can be categorized into two correlated but distinct aspects: self-benefitting and other-benefitting. Leader self-benefitting accountability refers to leaders’ attributions towards their own benefits (i.e., internal attribution of good performance and external attribution of poor performance). Leader other-benefitting accountability reflects leaders’ attributions towards others’ interests (i.e., internal attribution of poor performance and external attribution of good performance). Using multiple samples, I develop and validate a leader accountability scale, and then test a theoretical model with a focus on leader accountability and collective accountability (i.e., a group of individuals’ degree of ownership) by collecting data from 57 leaders and 162 followers in three Chinese companies. The findings show that leader humility is positively related to leader other-benefitting accountability. Both leader self-benefitting and other-benefitting accountability are associated with collective self-benefitting and other-benefitting accountability, respectively. Moreover, the relationship between leader self-benefitting and collective self-benefitting accountability is enhanced when the leader has high organization prototypicality. Furthermore, collective self-benefitting accountability decreases leader effectiveness and team effectiveness, while collective other-benefitting accountability increases leader effectiveness.

Description
Researchers lament that feedback interventions often fail. Traditional theories assume a cognitive relationship between the receipt of feedback and its impact on employee performance. I offer a theoretical model derived from Affective Events and Broaden and Build Theories to shed new light on the feedback-performance relationship. I bridge the two primary streams of feedback literature-the passive receipt and active seeking-to examine how employees' affective responses to feedback drive how they use feedback to improve performance. I develop and test a model whereby supervisor developmental feedback and coworker feedback seeking relate to the positivity ratio (the ratio of positive as compared to negative affect), enabling them to be more creative and thus improving their performance. I test my model using Experience Sampling Methodology with a sample of MBA students over a two week working period.

Description
This study develops a theoretical model that explains how leaders come to adapt their leadership behaviors to achieve follower effectiveness. Mindfulness theory suggests that mindful individuals are better able to engage in self-regulation and I consider empathy, response flexibility, and emotional regulation as three self-regulatory processes in particular which likely impact the leader-follower relationship. I suggest that leaders who have the ability to self-regulate in these three ways will be better able to engage in leadership behavior characterized by adapting or flexing the specific types of leadership they demonstrate according to the needs of the situation and what their followers most require at a given time to perform at their best. When followers receive the type of situationally-appropriate support in the form of leader behavior, they are more effective (e.g. have higher job performance and extra-role performance). I validate a new trait and state measure of workplace mindfulness with multiple samples and utilize this new scale to collect data from leaders and followers from a government organization to test the theoretical relationships proposed in this study. I utilize an experience sampling methodology (ESM) design over 10 days to investigate the within-leader variation among variables in the study given theory suggesting the dynamic nature of the mindfulness, self-regulation, and situational leadership constructs which may not adequately be captured when data are collected at one point in time. Finally, I introduce organizational constraints as a moderator of the relationship between leader mindfulness and leader self- regulation in order to understand how stressors and strains outside the control of a leader may overload a leader’s ability to ultimately self-regulate his/her behavior.

Description
Employees are directly involved in work tasks and processes which are necessary to accomplish unit or organizational goals, and accordingly, they may become aware of key mistakes, slips, and failures that are unbeknownst to the leader or supervisor responsible for the work unit or organization. Given that errors or deviations in work tasks or processes can have far-reaching effects within the organization, it may be essential for employees to share bad news with their leader or supervisor so that steps can be taken to address the issue or ameliorate negative consequences. However, although employees' sharing of bad news may be important to the organization and should be encouraged, supervisors may respond to the messenger in ways that discourage the behavior. Unfortunately, we lack an explanation of why and under what conditions supervisors respond positively or negatively to employees who share bad news. Thus, the purpose of this dissertation is to address this gap in our understanding. I draw from social exchange theory and the transactional theory of stress to develop a conceptual model of sharing bad news. I suggest that sharing bad news can be cast as a transaction between employees and supervisors that is mediated by supervisors’ appraisals of employees’ sharing the message. The quality of the relationship between an employee and supervisor, or leader-member exchange (LMX), is strengthened when supervisors appraise the sharing of bad news as challenging, or potentially rewarding; however, LMX is weakened when supervisors appraise the sharing of bad news as hindering, or potential harmful. In turn, LMX influences supervisor responses to the sharing of bad news in the form of evaluations of the employee’s effectiveness. In addition to these main effects, I also consider how aspects of the message delivery, such as the timeliness with which messages are conveyed and extent to which employees incorporate solutions when they share bad news, can influence supervisor appraisals of sharing bad news. Finally, I suggest that the extent to which the messenger is responsible for the bad news moderates the relationships between appraisals of sharing bad news and LMX. I test this model in three studies.

Description
This dissertation addresses two issues in the literature on informal leadership emergence (i.e., the process of an individual without a formal leadership position coming to exert leadership influence over others). First, scholars have focused on situations in which a focal person’s leadership claiming is aligned with a peer’s leadership granting. In doing so, past work has overlooked instances of misalignment, that is, when a focal person claims more leadership than a peer grants (i.e., overclaiming) or when a peer grants more leadership than a focal person claims (i.e., underclaiming). Second, the consensus in the literature suggests that emerging as an informal leader provides more beneficial outcomes to the individual and their team than non-emerging. However, I argue that this assumption may not be warranted in some situations, for example when a focal person’s lack of claiming is aligned with a peer’s lack of granting. Drawing on the leadership identity claiming and granting framework, I postulate four forms of informal leadership (non)emergence, namely (1) dyadic emergent leadership, (2) dyadic leadership absence, (3) overclaiming, and (4) underclaiming. Based on role theory, I then build theory regarding their effects on behavioral consequences through affective and cognitive mechanisms. More precisely, I suggest that forms characterized by congruence in leadership claiming and granting (as opposed to forms characterized by incongruence) result in increased peer backing-up behavior towards the focal person (mediated by enthusiasm and respect) and reduced peer social undermining (mediated by anger and revenge cognitions). I further hypothesize asymmetrical incongruence effects and consider a focal person’s prosocial motivation as a boundary condition. I conducted three studies to examine my theorizing. In Pilot Study 1 (N = 199), I adapted and validated a measure to assess leadership claiming and granting. In Pilot Study 2 (N = 151), I shortened established measures. In the Main Study (N = 279), I tested my theoretical predictions yielding mixed findings. Whereas I find support for the congruence effect on backing-up behavior, all other hypotheses were not supported. I report supplemental analyses to examine these null results and discuss the theoretical, empirical, and practical implications of this research.

Description
The unicellular microalga Haematococcus pluvialis has emerged as a promising biomass feedstock for the ketocarotenoid astaxanthin and neutral lipid triacylglycerol. Motile flagellates, resting palmella cells, and cysts are the major life cycle stages of H. pluvialis. Fast-growing motile cells are usually used to induce astaxanthin and triacylglycerol biosynthesis under stress conditions (high light or nutrient starvation); however, productivity of biomass and bioproducts are compromised due to the susceptibility of motile cells to stress. This study revealed that the Photosystem II (PSII) reaction center D1 protein, the manganese-stabilizing protein PsbO, and several major membrane glycerolipids (particularly for chloroplast membrane lipids monogalactosyldiacylglycerol and phosphatidylglycerol), decreased dramatically in motile cells under high light (HL). In contrast, palmella cells, which are transformed from motile cells after an extended period of time under favorable growth conditions, have developed multiple protective mechanisms - including reduction in chloroplast membrane lipids content, downplay of linear photosynthetic electron transport, and activating nonphotochemical quenching mechanisms - while accumulating triacylglycerol. Consequently, the membrane lipids and PSII proteins (D1 and PsbO) remained relatively stable in palmella cells subjected to HL. Introducing palmella instead of motile cells to stress conditions may greatly increase astaxanthin and lipid production in H. pluvialis culture.

Description
The unicellular green microalga Desmodesmus sp. S1 can produce more than 50% total lipid of cell dry weight under high light and nitrogen-limitation conditions. After irradiation by heavy 12C6+ ion beam of 10, 30, 60, 90 or 120 Gy, followed by screening of resulting mutants on 24-well microplates, more than 500 mutants were obtained. One of those, named D90G-19, exhibited lipid productivity of 0.298 g L-1⋅d-1, 20.6% higher than wild type, likely owing to an improved maximum quantum efficiency (Fv/Fm) of photosynthesis under stress. This work demonstrated that heavy-ion irradiation combined with high-throughput screening is an effective means for trait improvement. The resulting mutant D90G-19 may be used for enhanced lipid production.
