Researchers investigated the impact that a first-year college experience course had on students?? first-year grade point averages (GPAs) and retention rates. A sample of 109 first-year students enrolled in the course was compared to a sample of 326 students from the same university who had not taken the course. The goals of the experience course were to reduce attrition, increase grade point averages, and enhance academic skills. Without accounting for selection bias, those who took the course had similar retention rates and lower GPAs than those who did not take the course. After matching on propensity scores, the negative effects of the program on GPA were nullified and those in the program were more likely to enroll for a second year. Although the benefits from the course were weak, the positive impact of the program was more apparent after accounting for individual differences. 相似文献

It has been argued by both educationalists and social researchers that visual methods are particularly appropriate for the
investigation of people’s experiences of the school environment. The current and expected building work taking place in British
schools provides an opportunity for exploration of methods, as well as a need to establish ways to achieve this involvement
of a range of school users, including students. This article describes a consultation that was undertaken in a UK secondary
school as part of a participatory design process centred on the rebuilding of the school. A range of visual methods, based
on photographs and maps, was used to investigate the views of a diverse sample of school users, including students, teachers,
technical and support staff and the wider community. Reported here is the experience of using these tools, considering the
success of different visually-based methods in engaging a broad cross section of the school community and revealing useful
information. Using a range of visual methods allows a complex, but coherent, understanding of the particular school environment
to be constructed and developed. It is further argued that such a range of visual and spatial methods is needed to develop
appropriate understanding. The study, therefore, contributes to knowledge about specific visual research methods, appreciation
of the relationship between tools, and a general methodological understanding of visual methods’ utility for developing understanding
of the learning environment. 相似文献

OBJECTIVE: Because little is known about the role of family problem-solving processes in the development of mothers' competencies in feeding a very low birth-weight (VLBW) infant, we explored the contribution made by the competence in negotiating displayed by a mother and family member as they jointly problem solve infant-care issues. The infant's neonatal biomedical condition, maternal depressive symptoms, and family poverty status may also contribute to feeding competencies. DESIGN: A sample of 41 mothers of VLBW infants from 2 longitudinal studies who were observed during feeding at 1 and 8 months infant postterm age, with a family member of their choosing, participated in a dyadic problem-solving exercise. We assessed maternal feeding competencies with the Parent-Child Early Relational Assessment (Clark, 1997) and dyadic negotiating competence using an observational scale from the Iowa Family Interaction Rating Scales (Melby & Conger, 2001). We classified infant condition through medical record audit. Maternal depressive symptoms were assessed with the Center for Epidemiologic Studies-Depression (CES-D) Scale (L. S. Radloff, 1977), and family poverty status was determined through the mother's report of family income. RESULTS: Mothers' feeding competencies, structured into 2 factors, Parental Positive Affective Involvement, Sensitivity, and Responsiveness (PPAISR) and Parental Negative Affect and Behavior (PNAB, scored in the direction of low negativity) were stable from 1 to 8 months, accounting for the entire set of predictor variables. Neonatal biomedical condition had no effect on either PPAISR or PNAB; depressive symptoms were negatively associated with PNAB at 8 months; poverty status negatively predicted both PPAISR and PNAB at 1 and 8 months; and negotiating competence of the mother-family member dyad was positively associated with PNAB at 1 month. CONCLUSIONS: Evidence that family poverty status and dyadic negotiating competence were both associated with maternal feeding competencies supports inclusion of these family-level variables in a model of feeding competencies. A mother's negotiating competence with another family member who takes a responsible role in infant care may support maternal feeding competencies during a VLBW infant's early weeks when parenting patterns are forming. 相似文献

Introduction: Pharmacists need effective skills in accessing and using Internet‐based medicines information (IBMI) for themselves and their consumers. However, there is limited information regarding how pharmacists use the Internet. Objectives: To develop and use a research instrument to measure pharmacists’ Internet knowledge, search skills, evaluation of and opinions about using IBMI. Methods: A structured questionnaire examining general Internet knowledge, ability to search for and select pertinent IBMI, evaluation of IBMI, opinions about using IBMI and current Internet use was developed. Exploratory factor analysis was performed to analyse IBMI evaluation. Results: 208 pharmacists responded (response rate 20.6%). There was a large variation in pharmacists’ scores. Mean scores were low for General Internet Knowledge (mean 7.91 ± 3.62; scale 0–16), Search and Selection of IBMI (4.98 ± 2.91; 0–10) and Opinions on IBMI (44.51 ± 9.61; 0–80). Four factors [Professionalism of website (4 items; factor loading 0.62–0.87; Cronbach’s α 0.84), Disclosure (5; 0.37–0.79; 0.73), Appropriateness of content (5; 0.32–0.50; 0.65), Standard of information (6; 0.31–0.48; 0.58)] were extracted from the evaluation scale, explaining 36.89% of the total variance. Conclusions: A tool was developed to evaluate pharmacists’ skills and opinions in using IBMI. A wide range of skills and opinions highlighted the need for training in online information literacy. 相似文献

Introduction
Although the life expectancy for patients with cystic fibrosis (CF) has increased dramatically in the preceding decades, often the final therapeutic option for patients with end-stage CF is lung transplantation. Prior to transplantation, patients with severe disease may require mechanical ventilation. Those refractory to mechanical ventilation may require extracorporeal membrane oxygenation (ECMO). The purpose of this case report is to describe the physical therapy management of a patient who received ECMO as a bridge to lung transplantation.Case Presentation
A 16-year-old girl with severe acute respiratory failure due to a CF exacerbation eventually required ECMO to maintain adequate gas exchange. While on ECMO, she received physical therapy interventions ranging from therapeutic exercise, manual therapy, and integumentary protection techniques in addition to airway clearance techniques. Prior to her transplant, she was standing multiple times per day with moderate assistance, was sitting on the edge-of-bed, as well as taking steps to transfer to/from a chair. She successfully received a bilateral lung transplant after 8 days on ECMO.Conclusion
Physical therapy interventions, including out-of-bed mobility, can be safely provided to patients on portable ECMO as a bridge to lung transplantation. These interventions were focused on preventing the negative sequelae of bed rest, increasing her strength and endurance, as well as improving her level of consciousness and psychological well being in preparation for lung transplantation.Key Words: extracorporeal membrane oxygenation, lung transplantation, physical therapy, exercise 相似文献187.

Although traditional instructional design and technology (IDT) has largely been based on objectivism, in the past 20 years, constructivism has emerged as a dominant framework for IDT. Both perspectives, however, present shortcomings. This paper explores enactivism—an emerging new philosophical world view—as an alternative paradigm. It also investigates the possibilities offered by this new paradigm to IDT. The philosophical world view known as enactivism is reviewed to illustrate the similarities and differences among the three philosophical paradigms, namely, objectivism, constructivism and enactivism. Finally, details of enactivism and its implications for IDT are explored. 相似文献

In Part 1 of our word retriever column [QSE 23] you were introduced to two kinds of programs that examine text: search programs, whose main function is to locate words and phrases, and content analysis programs, which are intended primarily for taking word inventories. Since both kinds of program contain sophisticated software that can do much more than perform those basic functions, it is difficult to distinguish clearly between the two. When the programs include many capabilities, they begin to overlap. In the previous column we explained what word searches are good for and how they are set up. In this column, we will take a look at the other functions that can be performed by word retrievers. You might be working on a research project, or planning one for the future, in which the computer could take over some tedious and time‐consuming chores. Considering the vastness of the software market, it is difficult to keep track of what the software offers. Here is a list of operations that potentially are valuable for the qualitative researcher. [The programs mentioned in each section are referenced at the end of the column.] 相似文献
