The eight early childhood educators who participated in this study were admitted into a 60-credit statewide distance-delivered Associate of Applied Science (AAS) degree program at the University of Alaska. All eight educators were women of Alaska Native ancestry who lived and worked in remote and rural Native communities. Seven of these teachers were employed by Head Start programs and one taught preschool for a rural school district. A major goal of the statewide distance-delivered AAS program is that participants will become skilled observers of children and learn to use observation to make decisions that foster developmentally appropriate and culturally responsive services. All the course work in our AAS degree program involves actively doing and using observations of children. This study is based on a principle that intrinsic changes can occur in program management, curriculum development, and teacher practice when teachers learn how to use observation of children rather than external evaluation to make decisions about their programs. 相似文献

Coaching is a promising method for providing professional development, which takes many forms. One such form is real-time coaching through bug-in-ear technology. This study explored the social validity of bug-in-ear coaching when provided as a form of professional development with preservice and in-service early childhood educators. Data from two studies were qualitatively analyzed to describe early childhood educators’ perceptions of the acceptability of bug-in-ear coaching with respect to the learning opportunities provided, feasibility, difficulties, and child-level outcomes. Findings suggest that BIE is deemed to be important and effective at producing educator and child outcomes. Further, educators are satisfied with the intervention and view it to be an acceptable means for receiving professional development. 相似文献

Background and objective
Stroke volume variation (SVV) has high sensitivity and specificity in predicting fluid responsiveness. However, sinus rhythm (SR) and controlled mechanical ventilation (CV) are mandatory for their application. Several studies suggest a limited applicability of SVV in intensive care unit (ICU) patients. We hypothesized that the applicability of SVV might be different over time and within certain subgroups of ICU patients. Therefore, we analysed the prevalence of SR and CV in ICU patients during the first 24 h of PiCCO-monitoring (primary endpoint) and during the total ICU stay. We also investigated the applicability of SVV in the subgroups of patients with sepsis, cirrhosis, and acute pancreatitis.Methods
The prevalence of SR and CV was documented immediately before 1241 thermodilution measurements in 88 patients.Results: In all measurements, SVV was applicable in about 24%. However, the applicability of SVV was time-dependent: the prevalence of both SR and CV was higher during the first 24 h compared to measurements thereafter (36.1% vs. 21.9%; P<0.001). Within different subgroups, the applicability during the first 24 h of monitoring ranged between 0% in acute pancreatitis, 25.5% in liver failure, and 48.9% in patients without pancreatitis, liver failure, pneumonia or sepsis.Conclusions
The applicability of SVV in a predominantly medical ICU is only about 25%–35%. The prevalence of both mandatory criteria decreases over time during the ICU stay. Furthermore, the applicability is particularly low in patients with acute pancreatitis and liver failure.16.

Faced with demanding time constraints and the need to compete and communicate across a global market, firms have engaged in mergers and acquisitions (M&As) to accomplish various objectives, including, but not limited to, increasing growth potential and expanding product lines. Given the vital role of knowledge in the M&A context, the aim of this case study is to explore the literature in the area of M&As from a knowledge perspective and to investigate the knowledge variable in the local Hellenic Post-Merger Integration (PMI) of the Roche Consumer Health division acquired by Bayer, both leading multinational pharmaceutical companies. The study focuses on whether the stakeholders think that one specific factor, namely knowledge transfer, has helped them develop towards one high-performance body, and, if so, what were the most significant experiences leading to this development. We followed a number of employees from both. The results of the study provide a better understanding of the key drivers of the knowledge transfer in a PMI. The critical factors (macro and micro) encourage or discourage knowledge transfer in integrating organizations. The assessment took place approximately six months after the contractual completion of the acquisition and was based on the management and co-workers’ perception of how integration at the Greek Bayer company had progressed. The Orton case study was developed as a complement to the theoretical framework on intangible synergies in the M&A context. It provides a practical perspective regarding the complexities and peculiarities involved in each M&A operation by confronting the conceptual framework with field realities. 相似文献

Various factors oblige today's parents to entrust their children to a child-care worker (CCW), providing services in the domestic sphere, either at the child's parental house or at the day-care worker's (DCW's) own home. Taking this into account, this paper examines job offers and applications for DCWs published in a regional Swiss newspaper as well as other job offers and applications published on a website called bestnounou.ch. The parents often tend to use a variety of terms, which do not point to the child-caring or rearing activity itself, but rather emphasise sociological characteristics of the CCW (age, gender, civil status), requesting, for example, a “lady”, a “grandmother”, a “student”. Thereby, the parents present the child-care work as: (1) a secondary and temporary activity in relation to another major stable activity (motherhood, apprenticeship, retirement); and (2) an activity that does not require professional skills but inborn aptitudes. Moreover, employers use as synonyms distinctive terms, which refer to various categories of CCW and domestic workers, whose schedules of conditions and salaries are regulated and differ. The parents' inclination to use terms designating the most precarious and underpaid CCW underscores the importance of child-care in the domestic sphere. It leads also to a public image of child-care workers as being a fragmented, unstable, little qualified and economically inconsistent workforce, in contrast to the stable and structural need for their specific services, allowing parents to face their familial and professional responsibilities. 相似文献

An important development in the theory of brands has been the concept of a brand personality as part of the brand image. The construct of congruence relates the personality of brands to the self-concept of consumers. It is assumed that congruence between the recipient's perception of his or her own personality and his or her perception of the brand personality leads to a higher degree of loyalty. The congruence construct has been proven to be a loyalty-promoting factor in various studies for consumer good brands. Whether the influence of congruence also exists with regard to media brands has, however, not yet been examined. As a step to close the gap, this research explores the effects of congruence on consumer loyalty in the media, taking the leading German news magazine brands— Focus, Spiegel, and Stern—which are published in print and online, as a case. The study uses a structural equation model, which is estimated by the partial least squares method, based on a questionnaire answered by 736 respondents. The model was tested for all respondents and those with print and online preference separately. As a result, the influence of congruence on loyalty could also be detected in our media case. Differences of the impact within the models for print and online give rise to the assumption that a differentiated approach to brand management in these two fields has to be taken into consideration. 相似文献
