We reflect on and illustrate with concrete examples the various systematic and creative steps taken along the process of grounded theory (GT). This process led to the emergence of a theoretical framework centered on building reciprocity as a way of collaborating with socio-economically disadvantaged communities and a means for facilitating poverty-reduction initiatives. This article aims to present the systematic processes of analysis that lie behind the theoretical framework and to reflect on the lessons learned along the path to creating a GT. In this way, the emergence of the theoretical framework is examined along the different inductive and analytic steps, and the interrelation between concepts is discussed. Theoretical sensitivity, pacing, sampling, coding, memoing, and sorting in this research are illustrated and brought to light. 相似文献

Although boredom poses serious consequences for employees and organizations, research has paid little attention to this phenomenon, especially when compared to other job experiences such as overload. Building upon the Effort-Recovery Model, our study examines the impact of these two sub-optimal experiences, characterized by under- and over-stimulation, on burnout via three facets of rumination. Using a time lagged design with three measurement moments and a sample of 152 participants, we found partial support for our hypotheses. Boredom and overload led to emotional exhaustion and disengagement 2 weeks later, via an increase in affective rumination. Overload also increased emotional exhaustion via reduced detachment, yet boredom reduced emotional exhaustion by facilitating detachment. These findings stress the importance of addressing boredom as a pervasive, although often silent, workplace phenomenon. 相似文献

Fetal hearing experiences shape the linguistic and musical preferences of neonates. From the very first moment after birth, newborns prefer their native language, recognize their mother's voice, and show a greater responsiveness to lullabies presented during pregnancy. Yet, the neural underpinnings of this experience inducing plasticity have remained elusive. Here we recorded the frequency-following response (FFR), an auditory evoked potential elicited to periodic complex sounds, to show that prenatal music exposure is associated to enhanced neural encoding of speech stimuli periodicity, which relates to the perceptual experience of pitch. FFRs were recorded in a sample of 60 healthy neonates born at term and aged 12–72 hours. The sample was divided into two groups according to their prenatal musical exposure (29 daily musically exposed; 31 not-daily musically exposed). Prenatal exposure was assessed retrospectively by a questionnaire in which mothers reported how often they sang or listened to music through loudspeakers during the last trimester of pregnancy. The FFR was recorded to either a /da/ or an /oa/ speech-syllable stimulus. Analyses were centered on stimuli sections of identical duration (113 ms) and fundamental frequency (F0 = 113 Hz). Neural encoding of stimuli periodicity was quantified as the FFR spectral amplitude at the stimulus F0. Data revealed that newborns exposed daily to music exhibit larger spectral amplitudes at F0 as compared to not-daily musically-exposed newborns, regardless of the eliciting stimulus. Our results suggest that prenatal music exposure facilitates the tuning to human speech fundamental frequency, which may support early language processing and acquisition.
Research Highlights
- Frequency-following responses to speech were collected from a sample of neonates prenatally exposed to music daily and compared to neonates not-daily exposed to music.
- Neonates who experienced daily prenatal music exposure exhibit enhanced frequency-following responses to the periodicity of speech sounds.
- Prenatal music exposure is associated with a fine-tuned encoding of human speech fundamental frequency, which may facilitate early language processing and acquisition.
