This article presents the results of a survey of the Epilepsy Foundation affiliates in the United States and Puerto Rico, regarding the employment-related questions and concerns of people with epilepsy. The survey also explored how Epilepsy Foundation affiliates advise people with epilepsy about disclosing epilepsy status in the employment-seeking process. Some of the major employment-related questions and concerns reported by the affiliates included identifying resources to help in finding a job, questions about disclosure of epilepsy status in job applications, questions about job-related discrimination or Americans with Disabilities Act (ADA) violations, questions about the ADA, and questions about how to deal with co-workers or supervisors. Implications and design limitations are discussed.
Breast cancer screening programs do not reach all women at the same rate. Screening mammography use varies according to sociodemographic characteristics; mammography utilization is highest among women in their fifties but then decreases with age. In North Carolina, breast cancer is a particular burden for Black and lower-income women. Black women are more likely to be diagnosed with late stage disease, and their rate of breast cancer mortality is higher than it is for White women even though the incidence in White women is greater. Older, Black, and low-income women are less likely to obtain screening by mammography and clinical breast examination. The Black-White gap is even more pronounced among rural women, in part because they are more likely to be poor. The North Carolina Breast Cancer Screening Program (NC-BCSP) was established to increase the rate of regular mammography screening by an absolute 20% in 3 years among older Black women ages 50 and older in five rural counties in the eastern part of the state. In this paper, we describe the genesis of this comprehensive community intervention model, highlighting the behavioral science constructs, health education principles, and theories of behavioral and organizational change that form its conceptual foundation. NC-BCSP's theoretical foundations include the social ecological perspective, the PRECEDE model of health promotion, the Health Belief Model of individual change, and the "stages of change" transtheoretical model. We also review the experiences and lessons learned from two previous outreach initiatives in North Carolina that provided valuable "lessons" in the development of the NC-BCSP intervention model. In the second half of the paper, we describe the actual NC-BCSP interventions, activities, and evaluation tools, citing specific examples of how the underlying theories are implemented. NC-BCSP's goal goes beyond individual behavior change to raise low mammography screening rates among Black women in rural North Carolina. Its ultimate objective is to create linkages across agencies, and between agencies and communities, that will endure after the research project ends.
Increasingly, contemporary medical ethicists have become aware of the need to explicate a foundation for their various models of applied ethics. Many of these theories are inspired by the apparent incompatibility of patient autonomy and provider beneficence. The principle of patient autonomy derives its current primacy to a large extent from its legal origins. However, this principle seems at odds with the clinical reality. In the bioethical literature, the notion of authenticity has been proposed as an alternative foundational principle to autonomy. This article examines this proposal in reference to various existentialist philosophers (Heidegger, Sartre, Camus and Marcel). It is concluded that the principle of autonomy fails to do what it is commonly supposed to do: provide a criterion of distinction that can be invoked to settle moral controversies between patients and providers. The existentialist concept of authenticity is more promising in at least one crucial respect: It acknowledges that the essence of human life disappears from sight if life's temporal character is reduced to a series of present decisions and actions. This also implies that the very quest for a criterion that allows physicians to distinguish between sudden, unexpected decisions of their patients to be or not to be respected, without recourse to the patient's past or future, is erroneous.
Despite the tension between the United States and the Soviet Union in the early 1920's, the Rockefeller Foundation and the Rockefeller Institute for Medical Research found ways to assist I.P. Pavlov. In addition to providing scientific literature and financial aid, these institutions and their officers rendered important moral support to the scientific career of Pavlov during his later years. In 1923, as a guest of the Rockefeller Institute, Pavlov visited American scientific laboratories. In 1924, he requested and received a number of books on physiology, and during the 1930's the Foundation helped him to acquire equipment for his Leningrad laboratory.
To determine the impact of inbreeding and outbreeding on disease resistance and survival during colony foundation, nestmate (NM) and non-nestmate (NON) primary reproductives of the dampwood termite Zootermopsis angusticollis were exposed to a single or double dose of conidia of the entomopathogenic fungus Metarhizium anisopliae. Male and female primary reproductive pairs originating from the same parent colony had higher survivorship than NON pairs in control and conidia-exposure treatments. The survival advantage of NM primary reproductives increased with the intensity of pathogen challenge and was significantly greater in the single- and double-dose treatments than in the controls. Although NM pairs had significantly lower mortality than NON pairs, the survivorship of colonies stabilized as they matured and inbred and outbred colonies did not differ in offspring production. These results demonstrate that colony foundation by NON male and female reproductives may have a disease-related survival cost during this critical phase of their life cycle. There may also be a cost associated with lower offspring heterozygosity, but in the first generation this does not appear to significantly impact colony growth.
The paper addresses the integration of ethics into professional education related to the disciplines responsible for the conception and creation of the artificial (artefactual or technology). The ontological-epistemological paradigm of those disciplines is understood within the frame of the sciences of the artificial as established by Herbert Simon (1969). According to that paradigm, those sciences include disciplines not only related to the production of artefacts (technology), such as engineering, architecture, industrial design, etc, but also disciplines related to devised courses of action aimed at changing existing situations into preferred ones, like medicine, law, education, etc. They are centered on intentional action and at their core is the activity of design, which is their common foundation and attitude, or their common culture. The science of design becomes the broader foundational discipline for any professions engaged in the intentional transformation of the world. The main distinction between design disciplines and scientific ones rests on the object-project dichotomy. Indeed, contrary to Science that sees the world as an object to be observed, Design sees the world as a project and acts upon the world through projects, which are grounded in intentions, ends, and values. Design disciplines are meant to transform the world, or part of it, and are teleological. Being so, they are embodied in an act that is ethical and their ontology-epistemology must be addressed also through practical reason to resituate all professional disciplines according to their involved nature. The paper introduces theoretical, methodological, and ethical elements to establish a model that integrates ethics into the education of the professional disciplines, design-based disciplines, responsible for the creation of the artificial, artefactual or technological, world. The model is articulated around the notions of ethical engagement and responsibility through the act of design understood as action with intention situated in a project, common in all professional disciplines.
Accurate, timely data are a necessary foundation for an effective healthcare information management system. Today's systems do not achieve their potential because they lack this essential ingredient. Technology can reduce the problem by making the data entry task easier, but a complete solution will require new strategies for system implementation and use. Functions must be implemented in a sequence that allows the initial functions to establish a data foundation for subsequent functions. Each atomic data item must be collected separately, with a consistent definition. Data capture strategies must permit data to be collected once, at the source. Finally, the data must be used, reused, and corrected by all members of the healthcare team.
This longitudinal study examines the changes in patient-centredness of a group of student nurses during their Common Foundation Programme in Nursing, and attempts to explore some of the social, psychological and educational factors which might be associated with such change. The Patient-centredness Multi-choice Questionnaire (PMQX) was administered to a sample of 267 student nurses on commencement and completion of their Common Foundation Programme in Nursing, and significant positive as well as negative changes in PMQX scores were found, although the mean scores for the sample were unchanged. A number of factors were found to be associated with high levels of patient-centredness on commencement of the course, including marital status, age, and radicalism. Positive change in patient-centredness during the CFP was associated with a variety of variables such as class size, a student-centred climate and a tenderminded attitude. Other factors, such as psychological stability and extroversion, were associated with both increase and decrease in patient-centredness during the CFP.
From a study of the literature on the Philosophy of Physiology it became clear that a crisis exists. This crisis was studied by means of a classification of philosophical views. Two main categories, namely Positivistic and Transcendentalistic, frameworks of thought were used. Under the Positivistic category such models as radical materialistic, mechanistic and cybernetic were placed. Under the Transcendentalistic category were classified holistic, humanistic, mystic and eastern ideas. Paradoxic ideas were discussed. None of the frameworks of thought supply a good foundation for Physiology. A liberating foundation for Physiology is proposed. A model of man as a personal unity in a created environment is described. This model does not contain either the contradictions nor polarizations of the positivistic versus transcendentalistic frameworks of thought.
As the ambitions of synthetic biology approach genome-scale engineering, comprehensive characterization of cellular systems is required, as well as a means to accurately model cell-scale molecular interactions. These requirements are coincident with the goals of systems biology and, thus, systems biology will become the foundation for genome-scale synthetic biology. Systems biology will form this foundation through its efforts to reconstruct and integrate cellular systems, develop the mathematics, theory and software tools for the accurate modeling of these integrated systems, and through evolutionary mechanisms. As genome-scale synthetic biology is so enabled, it will prove to be a positive feedback driver of systems biology by exposing and forcing researchers to confront those aspects of systems biology which are inadequately understood.
This paper deals with the theoretical foundation to estimate the relative efficiency (probability of inferring the true tree) of different nucleotide substitution models. A novel theoretical approach has been developed to estimate the relative efficiency of nucleotide substitution models based on the neighbor-relation method. The theory was developed directly by using the four-point condition. Initially theoretical formulas for the Jukes-Cantor+gamma (JC+Gamma) model and the Jukes-Cantor (JC) model were developed to estimate their relative efficiencies. Theoretical formulas were used on several model topologies for both models to obtain a true tree. Extensive simulations were performed on the same set of trees to test the strength of the theoretical approach. Simulation results demonstrated a good agreement with results obtained by the theoretical estimation. Overall the theoretical foundation for estimating model efficiencies is very accurate.
The development of large semantic networks, such as the UMLS, which are intended to support a variety of applications, requires a flexible and efficient query interface for the extraction of information. Using one of the source vocabularies of UMLS as a test bed, we have developed such a prototype query interface. We first identify common classes of queries needed by applications that access these semantic networks. Next, we survey StruQL, an existing query language that we adopted, which supports all of these classes of queries. We then describe the OQAFMA Querying Agent for the Foundational Model of Anatomy (OQAFMA), which provides an efficient implementation of a subset of StruQL by pre-computing a variety of indices. We describe how OQAFMA leverages database optimization by converting StruQL queries to SQL. We evaluate the flexibility and efficiency of our implementation using English queries written by anatomists. This evaluation verifies that OQAFMA provides flexible, efficient access to one such large semantic network, the Foundational Model of Anatomy, and suggests that OQAFMA could be an efficient query interface to other large biomedical knowledge bases, such as the Unified Medical Language System.
A range of possible predictors of arithmetic and reading were assessed in a large sample (N=162) of children between ages 7 years 5 months and 10 years 4 months. A confirmatory factor analysis of the predictors revealed a good fit to a model consisting of four latent variables (verbal ability, nonverbal ability, search speed, and phonological memory) and two manifest variables (digit comparison and phoneme deletion). A path analysis showed that digit comparison and verbal ability were unique predictors of variations in arithmetic skills, whereas phoneme deletion and verbal ability were unique predictors of variations in reading skills. These results confirm earlier findings that phoneme deletion ability appears to be a critical foundation for learning to read (decode). In addition, variations in the speed of accessing numerical quantity information appear to be a critical foundation for the development of arithmetic skills.
The empirical literature on the measurement of health inequalities is vast and rapidly expanding. To date, however, no foundation in welfare economics exists for the proposed measures of health inequality. This paper provides such a foundation for commonly used measures like the health concentration index, the Gini index, and the extended concentration index. Our results indicate that these measures require assumptions that appear restrictive. One way forward may be the development of multi-dimensional extensions.
A common dental problem is restoring teeth with gingival or subgingival margins and extensive loss of coronal tooth structure. A technique is presented for doing so by making a wax foundation on the tooth and injecting vinyl polysiloxane impression material around the foundation to form a matrix for the tooth, using rubber dam clamps to stabilize the matrix.
This article describes a simple procedure for reproducing the internal contours of existing crowns to rebuild composite core foundations for endodontically treated abutment teeth. In the event of core fracture or recurrent caries under a crown, problems may be encountered when constructing a new dowel and core to retrofit an existing crown to the newly fabricated core. The procedure described in this article involves the use of a custom-made template and plastic foil to fabricate new composite core foundations for existing crowns.
