Purpose. The purpose of this study was to determine the perceptions of work engagement of Taiwanese nurses with 3 specific aims: (1) understand Taiwanese nurses' perceptions of work engagement; (2) explore the factors influencing work engagement, and (3) examine how work engagement impacts nursing care for patients. ^ Design. The study used an ethnographic approach with participant observation and semi-structured interviews with RNs. ^ Setting. The study was conducted in the highest and lowest nurse turnover medical surgical units at a regional teaching hospital in southwestern Taiwan. ^ Sample. Purposive sampling resulted in 28 formal interviews with RNs who provided direct patient care, had at least 3 months experience in nursing, and were full-time employees. ^ Methods. Descriptive data were collected through participant observation in each unit. Observations were made while attending meetings, continuing education sessions, and informal conversations with RNs. Field notes and audio recorded semi-structured interviews were analyzed using qualitative thematic analytic techniques. ^ Findings. Findings revealed perceptions of work engagement spanned four domains: patients ("wholehearted care"), work (positive attitude), self (fulfillment and happiness), and others (relationships with colleagues). Providing "wholehearted care" toward patients was the foundation of work engagement for nurses in Taiwan. Engaged nurses felt fulfilled, happy, and found "meaning" through the process of patient care. The study revealed five factors that influenced work engagement: personal, organizational, social, patient, and professional. The impact of work engagement on nurse and patient outcomes are confirmed. ^ Conclusions. Taiwanese nurses connect work engagement with patients, the job, oneself, and colleagues. "Wholehearted patient care" is the core manifestation of work engagement among these nurses. In contrast, studies in western business only focused on work attitudes. Losing interest and "heart" lead to work routines which can lead to individual unhappiness. Findings from this study validate the multiple factors contributing to work engagement of nurses. Job demands and resources can only partially explain what hinders work engagement. Work disengagement and burnout share some commonality but should be measured differently. An understanding of RNs' perceptions of work engagement may provide direction for strategies that improve work engagement leading to decreased RN turnover. ^

The Okinawa Trough (OT) in the East Asian continental margin is characterized by thick terrigenous sediment and ubiquitous volcanic-hydrothermal activities. In this study, the clays collected during IODP Expedition 331 to the middle OT (Iheya North Knoll) were analyzed for mineralogical and geochemical compositions. By comparing with the clays from the East China Sea shelf and surrounding rivers, we examine different clay origins. The hydrothermal field in the mid-OT is dominated by Mg-rich chlorite, while the recharge zone has clay mineral assemblages similar to the shelf and rivers, showing high content of illite, subordinate chlorite and kaolinite and scarce smectite. Compared to the terrigenous clays, the hydrothermal clays in the OT have high concentrations of Mg, Mn and Zr but low Fe, Na, K, Ca, Ba, Sr, P, Sc and Ti, while the hydrothermal clays in the mid-ocean ridge are relatively enriched in Fe and V and depleted in Al, Mg, Zr, Sc and Ti. Different fractionation patterns of rare earth elements also register in the terrigenous and hydrothermal clays, diagnostic of variable clay origins. We infer that the OT hydrothermal clay was primarily formed by the chemical alteration of detrital sediments subject to the hydrothermal fluids. The remarkably different compositions of hydrothermal clays between the sediment-rich back arc basin like OT and the sediment-starved ocean ridge suggest different physical and chemical processes of hydrothermal fluids and fluid-rock/sediment reactions under various geologic settings.
