This article describes a theoretical model of reading disability that integrates a wide range of research findings in cognitive psychology, reading, and education across the age and grade span. The model shows how reading disability relates to normal reading acquisition, and includes four possible patterns of reading disability: nonalphabetic readers, compensatory readers, nonautomatic readers, and readers delayed in the acquisition of word-recognition skills. We compare our model to the models of other investigators and argue that our model is especially useful to practitioners. Finally, we discuss some of the educational implications of the model.

Little research has been done to document the value of using nursing diagnosis in home care and the impact that increased acuity levels have had in diagnostic selection. Nursing diagnosis documentation in home care was examined to see whether it had a relation to select client and visit pattern variables. This retrospective chart audit, which piloted a newly developed instrument called the Home Care Audit Tool, utilized a sample of 199 closed records of a large midwestem Visiting Nurse Association. The mean age of the client population was 76 years, with 64% female. There were 269 initial nursing diagnoses cited in the sample records, averaging 1.75 diagnoses per case. The number of recorded visits increased when select nursing diagnoses were cited together in a single case. © 1994, Taylor & Francis Group, LLC. All rights reserved.

When establishing Nursing Ethics Committees (NECs), statewide nursing organizations play an important role in developing and disseminating resources. The Connecticut Nurses Association Ethics and Human Rights Committee surveyed 85 healthcare facilities to identify active NECs. Representatives facilitated other committees by providing guidelines and assistance to those agencies developing NECs — the ultimate goal. © 1994 by Springhouse Corporation.

Homelessness is one of the most pressing social problems today. Society has responded to the problem with the creation of homeless shelters. Yet, the nature of the operation of the shelter is not defined. This study explored the operations of two single adult homeless shelters to understand how they operate in addressing the problem of homelessness. The study identified two different types of services, one called `'house” and the other `'home”. House services provided basic food, shelter, and linkage to social services, which fulfilled the basic definition of the problem of homelessness as defined by the Institute of Medicine. Home services provided the basic services of house but also went one step beyond by providing these services within the context of a supportive environment, thus creating informal social supports. The study discusses the implications of each of these modalities in addressing the problems associated with people who are homeless as well as the differences in policies and structures which contribute to one shelter providing house and the other home services.

In three experiments, pigeons chose between a small amount of food delivered after a short delay and a larger amount delivered after a longer delay. A discrete-trial adjusting-delay procedure was used to estimate indifference points-pairs of delay-amount combinations that were chosen about equally often. In Experiment 1, when additional reinforcers were available during intertrial intervals on a variable-interval schedule, preference for the smaller, more immediate reinforcer increased. Experiment 2 found that this shift in preference occurred partly because the variable-interval schedule started sooner after the smaller, more immediate reinforcer, but there was still a small shift in preference when the durations and temporal locations of the variable-interval schedules were identical for both alternatives. Experiment 3 found greater increases in preference for the smaller, more immediate reinforcer with a variable-interval 15-s schedule than with a variable-interval 90-s schedule. The results were generally consistent with a model that states that the impact of any event that follows a choice response declines according to a hyperbolic function with increasing time since the moment of choice.

The alleged synthesis of nursing and public health has not produced the expected community-as-client emphasis. Public health is characterized as disease-focused, with masculine domination, using a causal model. The explanatory model of chaos challenges nurses to reexamine nursing's theoretical base by questioning assumptions associated with linear thinking. The selected chaotic concepts of aperiodicity, attractors, sensitive dependence on initial conditions, phase space, and fractals are discussed here. Each concept's connection to physics and mathematics is cited and considerations for nursing science are outlined. Conclusions include redefining health, nursing, and community in chaotic terms and renaming nursing practice, which has this aperiodic and holistic paradigm, as ecologic health nursing.

An individual's social support system comprises multiple networks. A lack in one system may cause an increased need for support in another. Social support has been found to be of vital impor tance to the health of the older adult client and caregiver. It has been found to have a significant influence on health outcomes, acting as a buffer and altering recovery patterns. This article de scribes the concept of social support and relates how the home health care nurse can assess this dimension and use the findings to better plan patient care in the home setting. Key words: social support, home care, older adult. © 1994, Sage Publications. All rights reserved.

This paper presents a fresh approach to a general education mathematics course. The basic idea is to turn the customary mathematics class on its head by focusing on applications first, through a reading of articles from magazines and newspapers, and then turning to the technical mathematical details. A description of the topics that were covered in my course, along with references to various publications, is given. A course such as this one is important because it conveys how mathematics is serving the goals of society. © 1994 Taylor and Francis Group, LLC.

Most studies of corporate social responsiveness (CSR) focus on the relationship between CSR and profit. Here, we use three perspectives (institutional theory, economic theory and agency theory) to explain CSR. Industry norms, market share and indicators of management reputation predict variance in CSR. The combined perspectives improve understanding of both CSR and the CSR-profit relationship in two ways. First, they suggest that CSR levels and their relationship with profit will vary by industry. Second, they suggest that stock market measures and accounting measures will respond differently to CSR measures. Stock market measures lead, while accounting measures lag, CSR.

In this study, breast cancer knowledge, beliefs and practices in low income black women were examined. First, focus groups were held with a total of 33 participants. Information gathered from the focus groups was used to develop a telephone survey which was partially based on the Health Belief Model (HBM) and administered to 92 subjects. Utilization rates of mammography and breast self-examination (BSE) were quite high; 66.3% of survey participants reported having at least one mammogram and 72.5% performed BSE. Because low-cost mammograms were available to the survey participants, these results suggest that women in this target population will utilize accessible and affordable mammograms. Several knowledge deficiencies that need to be addressed were also identified. Most of the health beliefs were not significantly associated with mammography or BSE utilization. Because the HBM has never been extensively tested on this population, its appropriateness as a behavior model for low-income women is examined. Implications for future research and interventions are discussed.
