Being “in Control” May Make You Lose Control: The Role of Self-Regulation in Unethical Leadership Behavior

In the present article, we argue that the constant pressure that leaders face may limit the willpower required to behave according to ethical norms and standards and may therefore lead to unethical behavior. Drawing upon the ego depletion and moral self-regulation literatures, we examined whether self-regulatory depletion that is contingent upon the moral identity of leaders may promote unethical leadership behavior. A laboratory experiment and a multisource field study revealed that regulatory resource depletion promotes unethical leader behaviors among leaders who are low in moral identity. No such effect was found among leaders with a high moral identity. This study extends our knowledge on why organizational leaders do not always conform to organizational goals. Specifically, we argue that the hectic and fragmented workdays of leaders may increase the likelihood that they violate ethical norms. This highlights the necessity to carefully schedule tasks that may have ethical implications. Similarly, organizations should be aware that overloading their managers with work may increase the likelihood of their leaders transgressing ethical norms

Out of Control!? How Loss of Self-Control Influences Prosocial Behavior: The Role of Power and Moral Values

Lack of self-control has been suggested to facilitate norm-transgressing behaviors because of the operation of automatic selfish impulses. Previous research, however, has shown that people having a high moral identity may not show such selfish impulses when their self-control resources are depleted. In the present research, we extended this effect to prosocial behavior. Moreover, we investigated the role of power in the interaction between moral identity and self-control depletion. More specifically, we expected that power facilitates the externalization of internal states, which implies that for people who feel powerful, rather than powerless, depletion decreases prosocial behavior especially for those low in moral identity. A laboratory experiment and a multisource field study supported our predictions. The present finding that the interaction between self-control depletion and moral identity is contingent upon people’s level of power suggests that power may enable people to refrain from helping behavior. Moreover, the findings suggest that if organizations want to improve prosocial behaviors, it may be effective to situationally induce moral values in their employees

Expressing forgiveness after interpersonal mistreatment: power and status of forgivers influence transgressors' relationship restoration efforts

One adverse consequence of interpersonal mistreatment is that it damages the relationship between the victim and the transgressor. Scholars have promoted forgiveness of such mistreatment as a victim response that can motivate transgressors to work towards relationship restoration. Building on social exchange theory and the social perception literature, we provide an account of when transgressors are less (vs. more) willing to restore their relationship with the victim in response to forgiveness. Specifically, we argue that transgressors perceive forgiveness from a victim who has high (vs. low) power, relative to the transgressor, as insincere, making transgressors less willing to restore the relationship. We further argue that this effect of high (vs. low) victim power is pronounced especially when the victim also has low (vs. high) status. Two experiments and two field studies support these predictions. These findings highlight the relevance of studying how contextual conditions color transgressors' perceptions of victims' behavior to understand relationship restoration after interpersonal mistreatment

Effect of viscosities of dispersed and continuous phases in microchannel oil-in-water emulsification

Although many aspects of microchannel emulsification have been covered in literature, one major uncharted area is the effect of viscosity of both phases on droplet size in the stable droplet generation regime. It is expected that for droplet formation to take place, the inflow of the continuous phase should be sufficiently fast compared to the outflow of the liquid that is forming the droplet. The ratio of the viscosities was therefore varied by using a range of continuous and dispersed phases, both experimentally and computationally. At high viscosity ratio (eta (d)/eta (c)), the droplet size is constant; the inflow of the continuous phase is fast compared to the outflow of the dispersed phase. At lower ratios, the droplet diameter increases, until a viscosity ratio is reached at which droplet formation is no longer possible (the minimal ratio). This was confirmed and elucidated through CFD simulations. The limiting value is shown to be a function of the microchannel design, and this should be adapted to the viscosity of the two fluids that need to be emulsified

In self-defense: reappraisal buffers the negative impact of low procedural fairness on performance

Contrary to an often-found result in the organizational justice literature, we suggest that there may be circumstances under which organization members will not perform poorly in response to being on the receiving end of low procedural fairness. To explain the theoretical mechanism, we integrate the group engagement model of justice with the emotion regulation perspective. Specifically, we argue that the detrimental effect of lower procedural fairness on performance is attenuated when individuals engage in reappraisal. Moreover, this is the case because reappraisal makes lower procedural fairness less likely to undermine self-perceived standing in the organization. Three experiments and a multisource survey among employees reveal support for these predictions. This research contributes to the organizational justice literature by showing that reappraisal can help maintain performance when people have experienced low procedural fairness, extending the typical finding that low procedural fairness undermines performance. Theoretical and practical implications, limitations, and suggestions for future research are discussed

Getting it done and getting it right: Leader disciplinary reactions to Followers’ moral transgressions are determined by construal level mindset

All normative leadership theories suggest that disciplining followers that transgress moral norms is a crucial leadership task. However, leaders sometimes yet fail to do so. Previous research has indicated that leaders may refrain from enacting discipline out of self-interest or from concern for the organization’s interest. We explore another option: leaders may simply be unwilling to enforce moral norms because of a negative attitude towards them. We argue and show that leaders that construe norms on relatively low (i.e. concrete) levels are likely to see norms as annoying obstacles, whereas leaders that construe moral norms on high (i.e. abstract) levels will have a more positive view of norms. In line with this, high construal level leaders are likely to be willing to enforce moral norms through discipline in response to follower moral transgressions. Low construal level leaders, in contrast, actively avoid doing so. We show this effect in different contexts and for different types of leader discipline

Power and leadership

Social collectives often grant power to leaders so they can facilitate collective performance. At present, there is no comprehensive overview of how power influences the effectiveness of different influence mechanisms leaders use to achieve this goal. To help develop such an overview, I review recent research on the positive and negative effects of power on some of these influence mechanisms: leaders’ punishment of norm transgressions, concern for followers, and procedural fairness enactment. I also highlight the role of individual differences and contextual factors in these processes. I end by discussing implications and future research directions

Two-Phase Oil-Water Empirical Correlation Models for SCAL and Petrophysical Properties in Intermediate Wet Sandstone Reservoirs

A consensus has long been established that the best secondary oil recovery through waterflood is attained in intermediate wet reservoir systems. In the absence of special core analysis (SCAL) data during the initial stages of field evaluation, experimentally-derived correlations are generated in this study for preliminary evaluation purposes. Currently, it is identified that ambiguity exists between petrophysical relationships in intermediate wet reservoirs. Clarifying these relationships provides us with further understanding into maximizing oil recovery in such systems. Hence, the main objective of this study is to analyse and provide further insights into the relationships between petrophysical properties, which are ultimately vital for reservoir simulations. The correlations are generated through linear regression analysis from experimental core measurements. It has been proven that the most reliable correlations are essentially empirical rather than theoretical, especially with the case of relative permeability. The variation of SCAL parameters and correlations generated are studied as a function of wettability, permeability, porosity, initial water saturation and rock type. It is observed that residual oil saturation is moderately correlated to Amott-Harvey wettability in an upward curvilinear relationship while scaled endpoint relative permeability in two-phase oil-water system is strongly and linearly correlated to wettability. When investigating the effects of permeability, one must take into account that having too low or too high value might present anomalies in the correlations. The general trend for intermediate wettability reservoir is that a higher permeability shows a shift towards less water-wet behaviour (shift to oil-wet). Moreover, for initial water saturation and wettability, the trend is towards more water-wet at higher initial water saturation. Meanwhile, porosity is not strongly correlated to any of the parameters except permeability

Fear and caring: procedural justice, trust, and collective identification as antecedents of voluntary tax compliance

We investigated the interactive roles of procedural justice of the tax authority, trust in the tax authority, and identification with the nation in predicting voluntary tax compliance. Drawing from fairness heuristic theory and relational models of justice, we predicted that the relationship between procedural justice and voluntary tax compliance that has been found particularly among citizens with low (vs. high) trust in the tax authorities is restricted to citizens who weakly (vs. strongly) identify with the nation. The results of a field study with samples of Ethiopian and US taxpayers as respondents largely support our predictions. This research integrates the role of important and well-studied social psychological factors that shape voluntary tax compliance and reveals support for the hypothesis in a developing (i.e., Ethiopia) and a developed (i.e., US) nation – nations with strongly divergent tax climates

Soft tissue sarcomas at a glance: clinical, histological, and MR imaging features of malignant extremity soft tissue tumors

Soft tissue sarcomas comprise approximately 1% of malignant tumors. There are more than 50 subtypes, but pleomorphic sarcoma, liposarcoma, leiomyosarcoma, synovial sarcoma, and malignant peripheral nerve sheath tumor account for 75%. Differentiation between these subtypes is difficult because they often present with a painless enlarging mass, and share many histological and MR imaging features. Nonetheless, subdifferentiation is important because the different subtypes have different prognoses and therapeutic strategies. In this manuscript we discuss the clinical, histological, and MR imaging features of soft tissue sarcomas according to the WHO classification. An overview is provided and differentiating features are discussed that can help to narrow down the differential diagnosis
