This paper makes use of a unique data set fordoctoral-level biochemists, earth scientists,physicists, and physiologists to examine the question ofwhether the rewards to publishing in science are gender blind. The longitudinal nature of the data, andthe inclusion of different research outcome variables,permit the estimation of a wage-change model thatcontrols for fixed effects and productivity differences. We find little evidence that the reward processin academe during the 1970s was affected by gender. Wedo, however, find evidence that catch-up was occurring,implying that all was not well in the past for the women scientists in the study. [The1975 Survey of Doctorate Recipients indicates thatracial minority groups (Blacks, American Indians, andAsians) comprised, respectively, 5.9%, 6.3%, 2.8%, and 6.3% of the doctoral populations in physics,chemistry, earth science, and thebiosciences.]  相似文献

The structure of businesses and the structure of families are very similar, considering the fact that so many businesses are owned or operated by families. Structural family therapists who are knowledgeable in systems theory and have an adequate understanding of the underlying concepts of structural family theory (including hierarchy, boundaries, and coalitions) can translate their knowledge to the structure of businesses and organizations. The purpose of this paper is to illustrate the similarities between the structures of families and businesses. In doing so, an application of structural family theory to the business world (employee assistance programs, business consultation, and family businesses) will be demonstrated.  相似文献

Recent studies have documented the increasing trend among school districts toward adopting full inclusion as the predominant model for serving students who qualify for special education services. Although these data may suggest that a paradigm shift has already taken place and that a consensus of opinion has been achieved, several organizations representing students with specific disabilities continue to support a continuum of placement options. This paper challenges a one size fits all approach to special education, and highlights the importance of considering the individual characteristics of students. The relevance of research on full inclusion, as well as methodological issues that limit generalizability of findings related to student outcomes, are discussed. The radical perspective of full inclusion is rejected in favor of an approach that emphasizes the complexities of placement decisions.  相似文献

Students with special needs must have the opportunity to learn in inclusive classrooms. However, this requires that classroom teachers believe that (a) students can learn in spite of any negative environmental influences in their lives, and (b) they personally have the ability to reach any student. Securing this teaching efficacy for teachers in inclusive classroom settings requires paradigm shifts in preservice and inservice teacher development programs with the precept that all students can learn and that we can assist them. The authors, one a regular and the other a special education teacher educator, collaborate to explore the issue of how best to provide and maintain a positive personal teaching efficacy among regular teacher education candidates who are faced with the challenges of having students with varying levels of ability and behavioral responses in their classrooms.  相似文献

对湖北省两所中学3219名初一至初三年级学生进行问卷调查,建立结构方程模型考察父母粗暴养育、核心自我评价、友谊质量和青少年智能手机成瘾的关系。结果发现:(1)核心自我评价在父母粗暴养育和青少年智能手机成瘾之间起部分中介作用,即父母粗暴养育既对青少年智能手机成瘾产生直接影响,也通过核心自我评价对青少年智能手机成瘾产生间接影响;(2)父母粗暴养育和核心自我评价的关系(中介作用的前半段路径)受到友谊质量的调节,即在高友谊质量和低友谊质量条件下,随着粗暴养育程度的增加,青少年核心自我评价均显著下降,但在高友谊质量的条件下,下降的程度更高。研究结果有助于揭示父母粗暴养育对青少年智能手机成瘾的影响及其作用机制,为预防和干预青少年智能手机成瘾带来一些重要的启示。  相似文献

Twenty-one children between the ages of 46 and 52 years made a speaker doll address other dolls that represented an adult, a peer, and a younger listener in command and request situations. Analyses of the politeness of the elicited directives revealed that the effect of the listener's age was greatest in the command situations,with the adult listener receiving the politest directives, followed by the peer and the younger child, respectively. The listener age effect diminished in the request situations, where the child had to ask a favor of the listener. In these situations, the children were very polite to all three listeners. The results are discussed in terms of status relationships between the speaker and the listener.This article is taken from a doctoral dissertation completed at the University of Wisconsin, Madison, under the direction of D. K. Vetter.  相似文献

One solution to the difficulty of running real-time applications under UNIX is to develop the application programs on an available UNIX system and execute them on a dedicated satellite processor. This combines the advantages of a powerful timesharing operating system with the real-time capabilities of a single-process system. PARASITE, a real-time satellite system, provides tools for developing the application program on the host and executing it on a satellite. A host utility serves to invoke the standard UNIX C compiler and link its output with the PARASITE library. The PARASITE library consists of routines that mimic the standard library and routines that read and write the real-time peripherals. PARASITE currently supports digital inputs and outputs, asynchronous serial-line interfaces, program-mable real-time clocks, and analog-to-digital and digital-to-analog converters. Another PARA-SITE utility downloads the object code of the user program and PARASITE support code into the satellite, where it runs independently. Once the application routine is executing on the satellite, it controls the satellite processor at all times and is continuously available for servicing hardware-generated interrupts. When a real-time peripheral interrupt routine is invoked by a hardware interrupt, it sends a software signal to the user program, in addition to processing the interrupt. This allows the user program to perform additional tasks that are specific to the application. All data to be permanently stored must be transferred to the host. Since the satellite has no direct access to the resources of the host, a process running on the host receives the data and manages files. PARASITE provides packet driver routines on both the host and the satellite, which together handle the data transmission protocol.  相似文献

In two experiments, water-deprived rats were exposed to tone-footshock pairings in a particular conditioning context. In Experiment 1, the training parameters were selected on the basis of parametric pilot data so as not to produce direct associations between the conditioning context and footshock. Despite independent evidence of no appreciable direct association between the conditioning context and footshock, animals tested in the conditioning context exhibited more lick suppression to the tone than other animals tested with the tone outside of the conditioning context. Thus, the conditioning context potentiated suppression to the tone in the absence of appreciable fear of the conditioning context. In Experiment 2, training parameters were used that permitted the formation of direct associations between the conditioning context and footshock; however, for half the animals, these associations to the context were then extinguished. With the tone absent, a comparison of extinguished animals tested either in the conditioning context or outside the conditioning context detected no differences in suppression, demonstrating the effectiveness of the extinction manipulation. However, other animals also subjected to extinction of direct context-footshock associations displayed greater suppression to the tone within the conditioning context than comparable animals tested outside the context. Collectively the data indicate that the superior retention-test performance seen within the training context can arise both from the commonly assumed direct associations between the training context and the unconditioned stimulus and from the potentiation by the training context of the associations between the nominal conditioned stimulus and unconditioned stimulus.  相似文献

The purpose of the present study was to evaluate the effectiveness of an intervention program designed to train preschool children in interpersonal problem solving skills. Forty preschool age children were randomly assigned to an experimental or control group. Experimental subjects were trained in interpersonal problem solving skills for ten weeks, four days per week, for a total of 10–13 hours. Problem-solving skills were assessed at pretest, posttest, and three months after training was completed. Seventy-eight percent of the children who participated in pretest and posttest were tested at follow-up. Results indicated that the experimental group, compared to the control group, showed a significant increase in both cognitive—verbal and behavioral interpersonal problem-solving skills from pretest to posttest and that these changes were maintained at follow-up testing. Discussion focuses on suggestions for future research and implications for applied settings.  相似文献
