Descriptive Versus Interpretive Phenomenology: Their Contributions to Nursing Knowledge

Abstract: A number of articles in the nursing literature discuss the differences between descriptive and interpretive approaches to doing phenomenology. A review of studies demonstrates, however, that many researchers do not articulate which approach guides the study, nor do they identify the philosophical assumptions on which the study is based. Such lack of clarity makes it difficult for the reader to obtain a sense of how the knowledge produced by the study is to be evaluated and used. In this article, the authors compare the philosophical components of descriptive and interpretive approaches to doing phenomenology and illustrate types of knowledge produced by each through reviewing specific studies. They focus on the various uses of phenomenology in generating useful knowledge for health care practice.

The relations among environmental disclosure, environmental performance, and economic performance: a simultaneous equations approach

Abstract: This study provides an integrated analysis of the interrelations among (1) environmental disclosure, (2) environmental performance, and (3) economic performance. Based on the argument that management's (unobservable) overall strategy affects each of these corporate responsibilities, we conjecture that prior literature's mixed results describing their interrelations may be attributable to the fact that researchers have not considered these functions to be jointly determined. After endogenizing these corporate functions in simultaneous equations models, we obtain results that suggest “good” environmental performance is significantly associated with “good” economic performance, and also with more extensive quantifiable environmental disclosures of specific pollution measures and occurrences.

Self-compassion and reactions to unpleasant self-relevant events: The implications of treating oneself kindly.

Abstract: Five studies investigated the cognitive and emotional processes by which self-compassionate people deal with unpleasant life events. In the various studies, participants reported on negative events in their daily lives, responded to hypothetical scenarios, reacted to interpersonal feedback, rated their or others’ videotaped performances in an awkward situation, and reflected on negative personal experiences. Results from Study 1 showed that self-compassion predicted emotional and cognitive reactions to negative events in everyday life, and Study 2 found that self-compassion buffered people against negative self-feelings when imagining distressing social events. In Study 3, self-compassion moderated negative emotions after receiving ambivalent feedback, particularly for participants who were low in self-esteem. Study 4 found that low-self-compassionate people undervalued their videotaped performances relative to observers. Study 5 experimentally induced a self-compassionate perspective and found that selfcompassion leads people to acknowledge their role in negative events without feeling overwhelmed with negative emotions. In general, these studies suggest that self-compassion attenuates people’s reactions to negative events in ways that are distinct from and, in some cases, more beneficial than self-esteem.
