Effective first aid and transportation influences injury-induced mortality. But few qualitative studies have been conducted so far in this area. The aim of this study was to identify the content of the first aid and patient transportation course based on experience gained from the Iran-Iraq war. This was a conventional qualitative content analysis study; a purposeful sample of 14 first aid and transportation experts who had worked during the Iran-Iraq war was recruited. We collected and analyzed the study data by using the semi-structured interview method and the conventional content analysis approach respectively. Each interview transcript was reviewed several times. Words, sentences, and paragraphs were labeled with codes. Codes were compared with each other and categorized according to their similarities. Similar sub-categories and categories were also grouped together and formed themes. Study participants' experiences of wartime first aid and transportation (FAT) education fell into two main themes including 'the congruence of education and educational needs' and 'managers' engagement in FAT education. The four main categories of these two themes were use of appropriate educational facilities, adopting effective teaching strategies, universal FAT education and specialized training skills. The two key requirements of the first aid and transportation courses are practicality and managerial engagement. We developed and provided specific guidance of FAT curriculum by using the study findings. This curriculum is recommended for educating FAT staffs, paramedics, emergency technicians, and military nurses.

To evaluate the clinical and radiographic features of pulmonary aspergillosis as they present in AIDS patients; in particular, to determine similarities and differences between Aspergillus infection in patients with AIDS vs those without AIDS. Six new cases of confirmed or probable pulmonary aspergillosis were discovered during a search of hospital records. These are reviewed with 30 previously reported cases with special attention to radiographic appearance of disease and how radiographic appearance influences clinical outcome. Symptoms of pulmonary aspergillosis in AIDS were nonspecific, most often including fever, cough, and dyspnea, and less commonly, chest pain or hemoptysis. Major risk factors for the development of pulmonary aspergillosis in patients with AIDS were steroid administration and neutropenia. Neutropenia was often a complication of therapies for AIDS, in particular, ganciclovir and zidovudine. Radiographic appearance of disease could be divided into three general categories. One third of the patients (13/36) presented with cavitary upper lobe disease resembling noninvasive or chronic necrotizing aspergillosis. Fatal hemoptysis occurred in 42 percent of patients with this form of disease. Twenty-two percent (8/36) of the cases presented as a nondescript focal alveolar opacity similar to invasive aspergillosis. In several patients, the focal infiltrate remained stable for several months, a feature that is unusual for aspergillosis in non-AIDS patients. The air crescent sign was present in none of the 36 reported cases. Patients with only focal disease had the best prognosis of patients with pulmonary aspergillosis. Bilateral alveolar or interstitial disease similar to invasive aspergillosis was present in 23 percent (9/36) of the patients. Bilateral disease appears to be a marker for disseminated infection and was associated with a high mortality due to aspergillosis. Two new forms of bronchial aspergillosis (5/36 cases) have been described

Global matching models have provided an important theoretical framework for recognition memory. Key predictions of this class of models are that (1) increasing the number of occurrences in a study list of some items affects the performance on other items (list-strength effect) and that (2) adding new items results in a deterioration of performance on the other items (list-length effect). Experimental confirmation of these predictions has been difficult, and the results have been inconsistent. A review of the existing literature, however, suggests that robust length and strength effects do occur when sufficiently similar hard-to-label items are used. In an effort to investigate this further, we had participants study lists containing one or more members of visual scene categories (bathrooms, beaches, etc.). Experiments 1 and 2 replicated and extended previous findings showing that the study of additional category members decreased accuracy, providing confirmation of the category-length effect. Experiment 3 showed that repeating some category members decreased the accuracy of nonrepeated members, providing evidence for a category-strength effect. Experiment 4 eliminated a potential challenge to these results. Taken together, these findings provide robust support for global matching models of recognition memory. The overall list lengths, the category sizes, and the number of repetitions used demonstrated that scene categories are well-suited to testing the fundamental assumptions of global matching models. These include (A) interference from memories for similar items and contexts, (B) nondestructive interference, and (C) that conjunctive information is made available through a matching operation.

Premenstrual dysphoric disorder, which affects 2%–5% of premenopausal women, was included in Appendix B of DSM-IV, “Criterion Sets and Axes Provided for Further Study.” Since then, aided by the inclusion of specific and rigorous criteria in DSM-IV, there has been an explosion of research on the epidemiology, phenomenology, pathogenesis, and treatment of the disorder. In 2009, the Mood Disorders Work Group for DSM-5 convened a group of experts to examine the literature on premenstrual dysphoric disorder and provide recommendations regarding the appropriate criteria and placement for the disorder in DSM-5. Based on thorough review and lengthy discussion, the work group proposed that the information on the diagnosis, treatment, and validation of the disorder has matured sufficiently for it to qualify as a full category in DSM-5. A move to the position of category, rather than a criterion set in need of further study, will provide greater legitimacy for the disorder and encourage the growth of evidence-based research, ultimately leading to new treatments.

PURPOSE To assess the marginal and internal gaps of the copings fabricated by computer-aided milling and direct metal laser sintering (DMLS) systems in comparison to casting method. MATERIALS AND METHODS Ten metal copings were fabricated by casting, computer-aided milling, and DMLS. Seven mesiodistal and labiolingual positions were then measured, and each of these were divided into the categories; marginal gap (MG), cervical gap (CG), axial wall at internal gap (AG), and incisal edge at internal gap (IG). Evaluation was performed by a silicone replica technique. A digital microscope was used for measurement of silicone layer. Statistical analyses included one-way and repeated measure ANOVA to test the difference between the fabrication methods and categories of measured points (α=.05), respectively. RESULTS The mean gap differed significantly with fabrication methods (P<.001). Casting produced the narrowest gap in each of the four measured positions, whereas CG, AG, and IG proved narrower in computer-aided milling than in DMLS. Thus, with the exception of MG, all positions exhibited a significant difference between computer-aided milling and DMLS (P<.05). CONCLUSION Although the gap was found to vary with fabrication methods, the marginal and internal gaps of the copings fabricated by computer-aided milling and DMLS fell within the range of clinical acceptance (<120 µm). However, the statistically significant difference to conventional casting indicates that the gaps in computer-aided milling and DMLS fabricated restorations still need to be further reduced.

This study analyses the way in which the Italian press reported Acquired Immunodeficiency Syndrome (AIDS) over a 22-month period from September 1993 to June 1995, when no national AIDS information campaigns were made in Italy. During this period we collected, read, and categorized every article relating to Human Immunodeficiency Virus (HIV) and AIDS in fourteen newspapers and two news magazines with the highest national circulation. Articles were then assigned to one of six content categories: statistics, basic science, cure and vaccine, education/awareness and prevention issue, government or non-goverment organizations response, and people with AIDS (PWA) personal portrayals. A total of 4,228 articles referring to HIV/AIDS were identified. Analysis of the featured topics reveals several clear differences in the coverage of aspects of AIDS. The major category was represented by government or non-goverment organization response which accounted for 1,341 articles. Overall, this analysis suggests that, even long after the beginning of the epidemic, the press continues to see AIDS as an important issue. However, the articles explaining scientifically the AIDS epidemic were very few. The majority of AIDS-related information was spread in consequence of sensational events. Further analysis of PWA coverage shows that most articles discussed news that could provoke a negative feeling towards HIV-infected patients among the general population.

The dynamics of the Brazilian AIDS epidemic was analyzed by occupation, taken as a proxy for individual socioeconomic status. The analysis comprised AIDS cases aged 20-49 and diagnosed in 1987-1998. The temporal trend in AIDS incidence rates was analyzed by sex, occupational category, and quintiles defined by a Brazilian scale for socioeconomic status (SES). The proportions of AIDS cases stratified by SES quintiles were analyzed by exposure category. Among men, incidence rates increased in the 1st time period in almost all occupational categories, decreasing among those classified as "non-manual" occupations during the 2nd period. Among females, an annual increment was observed from 1987 to 1998 in nearly all occupational strata. The highest relative increases were observed among the lowest SES scales for both sexes. The intravenous drug user (IDU) exposure category had the lowest socioeconomic status for both sexes, whereas the homo/bisexual category had the highest. The analysis highlighted a progressive change in the epidemic's social gradient during the period, with a faster spread among the lower socioeconomic strata.

The International Outcome Inventory for Hearing Aids (IOI-HA) was developed as a global hearing aid outcome measure targeting seven outcome domains. The published norms were based on a private-pay sample who were fitted with analog hearing aids. The purpose of this study was to evaluate the psychometric properties of the IOI-HA and to establish normative data in a veteran sample. Survey. The participants were 131 male veterans (mean age of 74.3 years, SD = 7.4) who were issued hearing aids with digital signal processing (DSP). Hearing aids with DSP that were fitted bilaterally between 2005 and 2007. Veterans were mailed two copies of the IOI-HA. The participants were instructed to complete the first copy of the questionnaire immediately and the second copy in two weeks. The completed questionnaires were mailed to the laboratory. The psychometric properties of the questionnaire were evaluated. As suggested by Cox and colleagues, the participants were divided into two categories based on their unaided subjective hearing difficulty. The two categories were (1) those with less hearing difficulty (none-to-moderate category) and (2) those who report more hearing difficulty (moderately severe+ category). The norms from the current veteran sample then were compared to the original, published sample. For each hearing difficulty category, the critical difference values were calculated for each item and for the total score. A factor analysis showed that the IOI-HA in the veteran sample had the identical subscale structure as reported in the original sample. For the total scale, the internal consistency was good (Chronbach's alpha = 0.83), and the test-retest reliability was high (lambda = 0.94). Group and individual norms were developed for both hearing difficulty categories in the veteran sample. For each IOI-HA item, the critical difference scores were < 1.0. This finding suggests that for any item on the IOI-HA, there is a 95 percent chance that an observed change of one

Sexually-transmitted diseases, AIDS and traditional healers in Mozambique.

1993-08-01

Qualitative research was conducted with traditional healers in Manica Province, Mozambique to develop an empirical, culturally-appropriate strategy for communication between government and traditional healers related to the prevention of STDs including AIDS. Most Manica healers regard AIDS as a new disease for which they lack medicines. However, when questioned on other sexually transmitted diseases, as defined by healers themselves, relatively complex disease taxonomies based on fine distinctions between symptoms emerged. Manica healers recognize two broad categories of STDs: siki and nyoka-related. The former seems to correspond with the more serious common STDs of Western biomedicine--syphilis, gonorrhea, chlamydia and chancroid--and is believed to be caused by a common invisible, microscopic agent, khoma. Nyoka-related illnesses are understood in terms of traditional ideas of pollution, and denote less serious, self-limiting genito-urinary conditions. Healers express great faith in the efficacy of traditional medicines. Based on the ethnomedical research findings, a culturally-sensitive and -specific AIDS/STD health education strategy for Manica indigenous healers was developed and began operating in a week-long workshop held in Chimoio, Mozambique in November 1991.

Feature-based versus category-based induction with uncertain categories.

PubMed

Griffiths, Oren; Hayes, Brett K; Newell, Ben R

2012-05-01

Previous research has suggested that when feature inferences have to be made about an instance whose category membership is uncertain, feature-based inductive reasoning is used to the exclusion of category-based induction. These results contrast with the observation that people can and do use category-based induction when category membership is known. The present experiments examined the conditions that drive feature-based and category-based strategies in induction under category uncertainty. Specifically, 2 experiments investigated whether reliance on feature-based inductive strategies is a product of the lack of coherence in the categories used in previous research or is due to the use of a decision-only induction procedure. Experiment 1 found that feature-based reasoning remained the preferred strategy even when categories with relatively high internal coherence were used. Experiment 2 found a shift toward category-based reasoning when participants were trained to classify category members prior to feature induction. Together, these results suggest that an appropriate conceptual representation must be formed through experience with a category before it is likely to be used as a basis for feature induction.

On Monoids in the Category of Sets and Relations

The category R e l is the category of sets (objects) and relations (morphisms). Equipped with the direct product of sets, R e l is a monoidal category. Moreover, R e l is a locally posetal 2-category, since every homset R e l( A, B) is a poset with respect to inclusion. We examine the 2-category of monoids R e l M o n in this category. The morphism we use are lax. This category includes, as subcategories, various interesting classes: hypergroups, partial monoids (which include various types of quantum logics, for example effect algebras) and small categories. We show how the 2-categorical structure gives rise to several previously defined notions in these categories, for example certain types of congruence relations on generalized effect algebras. This explains where these definitions come from.

Hearing loss is a leading cause of disability among older people. Yet only one in seven US adults who could benefit from a hearing aid uses one. This fraction has not increased over the past 30 years, nor have hearing aid prices dropped, despite trends of steady improvements and price reductions in the consumer electronics industry. The President's Council on Science and Technology has proposed changes in the regulation of hearing aids, including the creation of a "basic" low-cost over-the-counter category of devices. We discuss the potential to reduce disability as well as to improve public health, stakeholder responses to the president's council's proposal, and public health efforts to further mitigate the burden of disability stemming from age-related hearing loss.

Sodium Reduction in Processed Foods in Brazil: Analysis of Food Categories and Voluntary Targets from 2011 to 2017

2017-01-01

Non-communicable diseases, including cardiovascular diseases, are responsible for over 70% of deaths in Brazil. Currently, over 25% of Brazilian adults are diagnosed as hypertensive; overall, current dietary sodium intake in Brazil (4700 mg/person) is over twice the international recommendations, and 70–90% of adolescents and adults consume excessive sodium. National sodium reduction strategies consider the main dietary sources of sodium to be added salt to foods, foods consumed outside of the household, and sodium in processed foods. The national voluntary strategy for sodium reduction in priority food categories has been continuously monitored over a 6-year period (2011–2017) and there was a significant 8–34% reduction in the average sodium content of over half food categories. Different food categories have undergone differing reductions in sodium over time, aiding gradual biannual targets to allow industries to develop new technologies and consumers to adapt to foods with less salt. By 2017, most products of all food categories had met the regional targets proposed by the Pan American Health Organization, showing that voluntary sodium reduction strategies can potentially contribute to food reformulation. Nevertheless, regulatory approaches may still be necessary in the future in order to reach all food producers and to allow stronger enforcement to meet more stringent regional targets. PMID:28704932

An efficient robust sound classification algorithm for hearing aids.

PubMed

Nordqvist, Peter; Leijon, Arne

2004-06-01

An efficient robust sound classification algorithm based on hidden Markov models is presented. The system would enable a hearing aid to automatically change its behavior for differing listening environments according to the user's preferences. This work attempts to distinguish between three listening environment categories: speech in traffic noise, speech in babble, and clean speech, regardless of the signal-to-noise ratio. The classifier uses only the modulation characteristics of the signal. The classifier ignores the absolute sound pressure level and the absolute spectrum shape, resulting in an algorithm that is robust against irrelevant acoustic variations. The measured classification hit rate was 96.7%-99.5% when the classifier was tested with sounds representing one of the three environment categories included in the classifier. False-alarm rates were 0.2%-1.7% in these tests. The algorithm is robust and efficient and consumes a small amount of instructions and memory. It is fully possible to implement the classifier in a DSP-based hearing instrument.

Associations between Depressive Symptomatology and Neurocognitive Impairment in HIV/AIDS.

Mood disorders and neurocognitive impairments are debilitating conditions among patients with HIV/AIDS. How these comorbidities interact and their relationships to systemic factors remain uncertain. Herein, we investigated factors contributing to depressive symptomatology (DS) in a prospective cohort of patients with HIV/AIDS in active care that included neuropsychological assessment. Among patients with HIV/AIDS receiving combination antiretroviral therapy (cART) and ongoing clinical assessments including measures of sleep, health-related quality of life (HQoL), neuropsychological testing, and mood evaluation (Patient Health Questionnaire-9 [PHQ-9]) were performed. Univariate and multivariate analyses were applied to the data. In 265 persons, 3 categories of DS were established: minimal (PHQ-9: 0-4; n = 146), mild (PHQ-9: 5-9; n = 62), and moderate to severe (PHQ-9: 10+; n = 57). Low education, unemployment, diabetes, reduced adherence to treatment, HIV-associated neurocognitive disorders (HAND), low health-related quality of life (HQoL), reduced sleep times, and domestic violence were associated with higher PHQ-9 scores. Motor impairment was also associated with more severe DS. In a multinomial logistic regression model, only poor HQoL and shorter sleep duration were predictive of moderate to severe depression. In this multivariate model, the diagnosis of HAND and neuropsychological performance (NPz) were not predictive of DS. Symptoms of depression are common (45%) in patients with HIV/AIDS and represent a substantial comorbidity associated with multiple risk factors. Our results suggest that past or present immunosuppression and HAND are not linked to DS. In contrast, sleep quality and HQoL are important variables to consider in screening for mood disturbances among patients with HIV/AIDS and distinguishing them from neurocognitive impairments.

Hue distinctiveness overrides category in determining performance in multiple object tracking.

Sun, Mengdan; Zhang, Xuemin; Fan, Lingxia; Hu, Luming

2018-02-01

The visual distinctiveness between targets and distractors can significantly facilitate performance in multiple object tracking (MOT), in which color is a feature that has been commonly used. However, the processing of color can be more than "visual." Color is continuous in chromaticity, while it is commonly grouped into discrete categories (e.g., red, green). Evidence from color perception suggested that color categories may have a unique role in visual tasks independent of its chromatic appearance. Previous MOT studies have not examined the effect of chromatic and categorical distinctiveness on tracking separately. The current study aimed to reveal how chromatic (hue) and categorical distinctiveness of color between the targets and distractors affects tracking performance. With four experiments, we showed that tracking performance was largely facilitated by the increasing hue distance between the target set and the distractor set, suggesting that perceptual grouping was formed based on hue distinctiveness to aid tracking. However, we found no color categorical effect, because tracking performance was not significantly different when the targets and distractors were from the same or different categories. It was concluded that the chromatic distinctiveness of color overrides category in determining tracking performance, suggesting a dominant role of perceptual feature in MOT.

Objective Based upon Damasio's “Convergence Zone” model of semantic memory, we predicted that epilepsy surgical patients with anterior temporal lobe (TL) seizure onset would exhibit a pattern of category-specific naming and recognition deficits not observed in patients with seizures arising elsewhere. Methods We assessed epilepsy patients with unilateral seizure onset of anterior TL or other origin (n = 22), pre- or postoperatively, using a set of category-specific items and a conventional measure of visual naming (Boston Naming Test: BNT). Results Category-specific naming deficits were exhibited by patients with dominant anterior TL seizure onset/resection for famous faces and animals, while category-specific recognition deficits for these same categories were exhibited by patients with nondominant anterior TL onset/resection. Patients with other seizure onset did not exhibit category-specific deficits. Naming and recognition deficits were frequently not detected by the BNT, which samples only a limited range of stimuli. Interpretation Consistent with the “convergence zone” framework, results suggest that the nondominant anterior TL plays a major role in binding sensory information into conceptual percepts for certain stimuli, while dominant TL regions function to provide a link to verbal labels for these percepts. Although observed category-specific deficits were striking, they were often missed by the BNT, suggesting that they are more prevalent than recognized in both pre- and postsurgical epilepsy patients. Systematic investigation of these deficits could lead to more refined models of semantic memory, aid in the localization of seizures, and contribute to modifications in surgical technique and patient selection in epilepsy surgery to improve neurocognitive outcome.

While the International Prognostic Index is commonly used to predict outcomes in immunocompetent patients with aggressive B-cell non-Hodgkin lymphomas, HIV-infection is an important competing risk for death in patients with AIDS-related lymphomas. We investigated whether a newly created prognostic score (AIDS-related lymphoma International Prognostic Index) could better assess risk of death in patients with AIDS-related lymphomas. We randomly divided a dataset of 487 patients newly diagnosed with AIDS-related lymphomas and treated with rituximab-containing chemoimmunotherapy into a training (n=244) and validation (n=243) set. We examined the association of HIV-related and other known risk factors with overall survival in both sets independently. We defined a new score (AIDS-related lymphoma International Prognostic Index) by assigning weights to each significant predictor [age-adjusted International Prognostic Index, extranodal sites, HIV-score (composed of CD4 count, viral load, and prior history of AIDS)] with three risk categories similar to the age-adjusted International Prognostic Index (low, intermediate and high risk). We compared the prognostic value for overall survival between AIDS-related lymphoma International Prognostic Index and age-adjusted International Prognostic Index in the validation set and found that the AIDS-related lymphoma International Prognostic Index performed significantly better in predicting risk of death than the age-adjusted International Prognostic Index (P=0.004) and better discriminated risk of death between each risk category (P=0.015 vs. P=0.13). Twenty-eight percent of patients were defined as low risk by the ARL-IPI and had an estimated 5-year overall survival (OS) of 78% (52% intermediate risk, 5-year OS 60%; 20% high risk, 5-year OS 50%).

Category mistakes: A barrier to effective environmental management.

PubMed

Wallace, Ken J; Jago, Mark

2017-09-01

How entities, the things that exist, are defined and categorised affects all aspects of environmental management including technical descriptions, quantitative analyses, participatory processes, planning, and decisions. Consequently, ambiguous definitions and wrongly assigning entities to categories, referred to as category mistakes, are barriers to effective management. Confusion caused by treating the term 'biodiversity' variously as the property of an area, the biota of an area, and a preferred end state (a value) - quite different categories of entities - is one example. To overcome such difficulties, we develop and define four entity categories - elements, processes, properties, and values - and two derived categories - states and systems. We argue that adoption of these categories and definitions will significantly improve environmental communication and analysis, and thus strengthen planning and decision-making.

Category labels versus feature labels: category labels polarize inferential predictions.

PubMed

Yamauchi, Takashi; Yu, Na-Yung

2008-04-01

What makes category labels different from feature labels in predictive inference? This study suggests that category labels tend to make inductive reasoning polarized and homogeneous. In two experiments, participants were shown two schematic pictures of insects side by side and predicted the value of a hidden feature of one insect on the basis of the other insect. Arbitrary verbal labels were shown above the two pictures, and the meanings of the labels were manipulated in the instructions. In one condition, the labels represented the category membership of the insects, and in the other conditions, the same labels represented attributes of the insects. When the labels represented category membership, participants' responses became substantially polarized and homogeneous, indicating that the mere reference to category membership can modify reasoning processes.

Nothing prepared me to manage AIDS.

PubMed

Banas, G E

1992-01-01

Articles and seminars about AIDS in the workplace are not adequate preparation for the genuine problems faced by actual managers in real organizations. There are no easy, win-win solutions to the impossible dilemmas AIDS presents, only various forms of damage control and, at best, more or less humane compromises. Gary Banas knows. Over a period of four years, two of his direct reports developed AIDS, and he watched them suffer through debility, slowly deteriorating performance, and eventual death. He also watched the gradual decline of their subordinates' productivity and morale. He found that, to different degrees, both men refused to acknowledge their illness and their decreasing organizational effectiveness. One of them resisted the author's efforts to give him an easier job at no loss in salary. Both insisted on confidentiality long after the rumor mill had identified their problem. In the course of these two consecutive ordeals, Banas discovered that AIDS patients fall into no single, neat category. AIDS is not an issue but a disease, and the people who get it are human beings first and victims second. He also learned that AIDS affects everyone around the sick individual and that almost every choice a manager makes will injure someone. Finally, he came to understand that while managers have an unequivocal obligation to treat AIDS-afflicted employees with compassion and respect, they have an equally unequivocal obligation to keep their organizations functioning. "Don't let anyone kid you," Banas warns. "When you confront AIDS in the workplace, you will face untenable choices that seem to pit your obligation to humanity against your obligation to your organization.(ABSTRACT TRUNCATED AT 250 WORDS)

Hearing Aid Assembly

Progress in hearing aids has come a long way. Yet despite such progress hearing aids are not the perfect answer to many hearing problems. Some adult ears cannot accommodate tightly fitting hearing aids. Mouth movements such as chewing, talking, and athletic or other active endeavors also lead to loosely fitting ear molds. It is well accepted that loosely fitting hearing aids are the cause of feedback noise. Since feedback noise is the most common complaint of hearing aid wearers it has been the subject of various patents. Herein a hearing aid assembly is provided eliminating feedback noise. The assembly includes the combination of a hearing aid with a headset developed to constrict feedback noise.

Contextual memory and skill transfer in category search.

PubMed

Kole, James A; Healy, Alice F; Fierman, Deanna M; Bourne, Lyle E

2010-01-01

In three experiments, we examined transfer and contextual memory in a category search task. Each experiment included two phases (training and test), during which participants searched through category and exemplar menus for targets. In Experiment 1, the targets were from one of two domains during training (grocery store or department store); the domain was either the same or changed at test. Also, the categories were organized in one of two ways (alphabetically or semantically); the organization either remained the same or changed at test. In Experiments 2 and 3, domain and organization were held constant; however, categories or exemplars were the same, partially replaced, or entirely replaced across phases in order to simulate the dynamic nature of category search in everyday situations. Transfer occurred at test when the category organization or domain was maintained and when the categories or exemplars matched (partially or entirely) those at training. These results demonstrate that transfer is facilitated by overlap in training and testing contexts.

Women and HIV/AIDS in the kingdom of Swaziland: culture and risks.

PubMed

Mathunjwa, Tengetile R; Gary, Faye A

2006-12-01

In Swaziland, a polygamous society in Southern Africa, the prevalence of the human immune virus/acquired immune deficiency syndrome (HIV/AIDS) is continuing to proliferate at an alarming rate. In 1992 the prevalence rate was 3.9%. However in 12 years, by 2004, the prevalence rate had reached 42.6%. This article explores some of the traditional cultural practices and experiences that increase Swazi women's vulnerability to HIV/AIDS. The traditional cultural practices fall into four categories: (1) socialization and the roles of women, (2) the minority status of women, (3) the practice of a dowry, and (4) the wife as an inheritance. The women's experiences include the Swazi men's beliefs in the virginity cure myth, the women's extreme poverty, and the Swazi men who are migrant workers in neighboring states. This article concludes with recommendations for public policy and for future research within the context of Swazi culture.

1995-01-01

To analyze HIV homosexual transmission in Mexico, epidemic trends and biological and social risk factors. This analysis is based on 19,090 notifications of AIDS cases and on a review of two previous studies that include 3,029 behavioral interviews (together with HIV serological screening tests) carried out at the Information Center of the Mexican Council for Control and Prevention of AIDS (CONASIDA) (1988-89) and during a 1988 study in six Mexican cities. Cities were included because they were the larger in the country and/or because they were the larger in the country and/or because they were touristic places (Mexico City, Guadalajara, Monterrey, Acapulco, Tijuana and Merida). Logistic regressions were used to estimate the odds ratios for HIV seropositivity and for condom use. Seventy-two percent of the total reported AIDS cases (19,090) up to June 30, 1994, were associated with male homosexual behaviors. In absolute numbers, cases under this category exhibited a rising trend until the end of 1993. HIV seroprevalence was 31% in 2,314 men with homosexual practices who attended "FLORA", the AIDS Information Center in Mexico, from January 1988 to June 30, 1989. The main predictive variables for seropositivity were exclusive homosexual behavior, more than 40 lifetime sexual partners, mixed sexual behavior (both insertive and receptive and intercourse), sex with a person with AIDS, history of syphilis, and anal or genital warts. In general, these risk factors (data from the Information Center) are similar to those found in the six Mexican cities study. There were significant differences in HIV prevalence among the high-risk city samples (the highest in Mexico City with 25% and the lowest in Monterrey with 2.4%). Reported condom use was very low in both studies: only 5% used a condom in all of their sexual relationships. A statistically significant protective effect for HIV infection was found only for those who reported using a condom in all sexual encounters. In the

Patient preference is one of the main components of clinical decision making, therefore leading to the development of patient decision aids. The goal of this study was to describe physicians' and patients' viewpoints on the barriers and limitations of using patient decision aids in Iran, their proposed solutions, and, the benefits of using these tools. This qualitative study was conducted in 2011 in Iran by holding in-depth interviews with 14 physicians and 8 arthritis patient. Interviewees were selected through purposeful and maximum variation sampling. As an example, a patient decision aid on the treatment of knee arthritis was developed upon literature reviews and gathering expert opinion, and was presented at the time of interview. Thematic analysis was conducted to analyze the data by using the OpenCode software. The results were summarized into three categories and ten codes. The extracted categories were the perceived benefits of using the tools, as well as the patient-related and physician-related barriers in using decision aids. The following barriers in using patient decision aids were identified in this study: lack of patients and physicians' trainings in shared decision making, lack of specialist per capita, low treatment tariffs and lack of an exact evaluation system for patient participation in decision making. No doubt these barriers demand the health authorities' special attention. Hence, despite patients and physicians' inclination toward using patient decision aids, these problems have hindered the practical usage of these tools in Iran--as a developing country.

The current study was aimed at understanding the social representation of hearing aids in India, Iran, Portugal, and the United Kingdom. We also compared these results to explore the cross-cultural differences and similarities among these countries. The study involved a cross-sectional design, and the data were collected from four different countries using the snowball sampling method. Data were analyzed using a content analysis to identify the most-similar categories of responses reported, a co-occurrences analysis to see which of these categories are reported commonly, and a chi-square analysis to study if there was any association between positive, neutral, and negative connotations among participants in different countries. The current study revealed four different social representations of hearing aids from India, Iran, Portugal, and the United Kingdom, and also a global index. The study results provide very useful insights into how hearing aids are represented in the society. These findings may have important implications for public education and also for manufacturers from the viewpoint of designing and marketing hearing aids in different countries.

Discontinuous categories affect information-integration but not rule-based category learning.

2005-07-01

Three experiments were conducted that provide a direct examination of within-category discontinuity manipulations on the implicit, procedural-based learning and the explicit, hypothesis-testing systems proposed in F. G. Ashby, L. A. Alfonso-Reese, A. U. Turken, and E. M. Waldron's (1998) competition between verbal and implicit systems model. Discontinuous categories adversely affected information-integration but not rule-based category learning. Increasing the magnitude of the discontinuity did not lead to a significant decline in performance. The distance to the bound provides a reasonable description of the generalization profile associated with the hypothesis-testing system, whereas the distance to the bound plus the distance to the trained response region provides a reasonable description of the generalization profile associated with the procedural-based learning system. These results suggest that within-category discontinuity differentially impacts information-integration but not rule-based category learning and provides information regarding the detailed processing characteristics of each category learning system.

Incidental Auditory Category Learning

PubMed Central

Gabay, Yafit; Dick, Frederic K.; Zevin, Jason D.; Holt, Lori L.

2015-01-01

Very little is known about how auditory categories are learned incidentally, without instructions to search for category-diagnostic dimensions, overt category decisions, or experimenter-provided feedback. This is an important gap because learning in the natural environment does not arise from explicit feedback and there is evidence that the learning systems engaged by traditional tasks are distinct from those recruited by incidental category learning. We examined incidental auditory category learning with a novel paradigm, the Systematic Multimodal Associations Reaction Time (SMART) task, in which participants rapidly detect and report the appearance of a visual target in one of four possible screen locations. Although the overt task is rapid visual detection, a brief sequence of sounds precedes each visual target. These sounds are drawn from one of four distinct sound categories that predict the location of the upcoming visual target. These many-to-one auditory-to-visuomotor correspondences support incidental auditory category learning. Participants incidentally learn categories of complex acoustic exemplars and generalize this learning to novel exemplars and tasks. Further, learning is facilitated when category exemplar variability is more tightly coupled to the visuomotor associations than when the same stimulus variability is experienced across trials. We relate these findings to phonetic category learning. PMID:26010588

From Statistics to Meaning: Infants’ Acquisition of Lexical Categories

PubMed Central

Lany, Jill; Saffran, Jenny R.

2013-01-01

Infants are highly sensitive to statistical patterns in their auditory language input that mark word categories (e.g., noun and verb). However, it is unknown whether experience with these cues facilitates the acquisition of semantic properties of word categories. In a study testing this hypothesis, infants first listened to an artificial language in which word categories were reliably distinguished by statistical cues (experimental group) or in which these properties did not cue category membership (control group). Both groups were then trained on identical pairings between the words and pictures from two categories (animals and vehicles). Only infants in the experimental group learned the trained associations between specific words and pictures. Moreover, these infants generalized the pattern to include novel pairings. These results suggest that experience with statistical cues marking lexical categories sets the stage for learning the meanings of individual words and for generalizing meanings to new category members.

To review the adhesive bonding to different computer-aided design/computer-aided manufacturing (CAD/CAM) esthetic restorative materials. The use of CAD/CAM esthetic restorative materials has gained popularity in recent years. Several CAD/ CAM esthetic restorative materials are commercially available. Adhesive bonding is a major determinant of success of CAD/ CAM restorations. Review result: An account of the currently available bonding strategies are discussed with their rationale in various CAD/ CAM materials. Different surface treatment methods as well as adhesion promoters can be used to achieve reliable bonding of CAD/CAM restorative materials. Selection of bonding strategy to such material is determined based on its composition. Further evidence is required to evaluate the effect of new surface treatment methods, such as nonthermal atmospheric plasma and self-etching ceramic primer on bonding to different dental ceramics. An understanding of the currently available bonding strategies to CA/CAM materials can help the clinician to select the most indicated system for each category of materials.

On Anaphora and the Binding Principles in Categorial Grammar

NASA Astrophysics Data System (ADS)

Morrill, Glyn; Valentín, Oriol

In type logical categorial grammar the analysis of an expression is a resource-conscious proof. Anaphora represents a particular challenge to this approach in that the antecedent resource is multiplied in the semantics. This duplication, which corresponds logically to the structural rule of contraction, may be treated lexically or syntactically. Furthermore, anaphora is subject to constraints, which Chomsky (1981) formulated as Binding Principles A, B, and C. In this paper we consider English anaphora in categorial grammar including reference to the binding principles. We invoke displacement calculus, modal categorial calculus, categorial calculus with limited contraction, and entertain addition of negation as failure.

Valuation, Categories and Attributes

Galperin, Inna; Sorenson, Olav

2014-01-01

Existing research on categories has only examined indirectly the value associated with being a member of a category relative to the value of the set of attributes that determine membership in that category. This study uses survey data to analyze consumers' preferences for the "organic” label versus for the attributes underlying that label. We found that consumers generally preferred products with the category label to those with the attributes required for the organic label but without the label. We also found that the value accorded to the organic label increased with the number of attributes that an individual associated with the category. Category membership nevertheless still had greater value than even that of the sum of the attributes associated with it. PMID:25111831

Category inference as a function of correlational structure, category discriminability, and number of available cues.

PubMed

Lancaster, Matthew E; Shelhamer, Ryan; Homa, Donald

2013-04-01

Two experiments investigated category inference when categories were composed of correlated or uncorrelated dimensions and the categories overlapped minimally or moderately. When the categories minimally overlapped, the dimensions were strongly correlated with the category label. Following a classification learning phase, subsequent transfer required the selection of either a category label or a feature when one, two, or three features were missing. Experiments 1 and 2 differed primarily in the number of learning blocks prior to transfer. In each experiment, the inference of the category label or category feature was influenced by both dimensional and category correlations, as well as their interaction. The number of cues available at test impacted performance more when the dimensional correlations were zero and category overlap was high. However, a minimal number of cues were sufficient to produce high levels of inference when the dimensions were highly correlated; additional cues had a positive but reduced impact, even when overlap was high. Subjects were generally more accurate in inferring the category label than a category feature regardless of dimensional correlation, category overlap, or number of cues available at test. Whether the category label functioned as a special feature or not was critically dependent upon these embedded correlations, with feature inference driven more strongly by dimensional correlations.

Effects of vitamins, including vitamin A, on HIV/AIDS patients.

PubMed

Mehta, Saurabh; Fawzi, Wafaie

2007-01-01

An estimated 25 million lives have been lost to acquired immune-deficiency syndrome (AIDS) since the immunodeficiency syndrome was first described in 1981. The progress made in the field of treatment in the form of antiretroviral therapy (ART) for HIV disease/AIDS has prolonged as well as improved the quality of life of HIV-infected individuals. However, access to such treatment remains a major concern in most parts of the world, especially in the developing countries. Hence, there is a constant need to find low-cost interventions to complement the role of ART in prevention of HIV infection and slowing clinical disease progression. Nutritional interventions, particularly vitamin supplementation, have the potential to be a low-cost method for being such an intervention by virtue of their modulation of the immune system. Among all the vitamins, the role of vitamin A has been studied most extensively; most observational studies have found that low vitamin A levels are associated with increased risk of transmission of HIV from mother to child. This finding has not been supported by large randomized trials of vitamin A supplementation; on the contrary, these trials have found that vitamin A supplementation increases the risk of mother-to-child transmission (MTCT). There are a number of potential mechanisms that might explain these contradictory findings. One is the issue of reverse causality in observational studies-for instance, advanced HIV disease may suppress release of vitamin A from the liver. This would lead to low levels of vitamin A in the plasma despite the body having enough vitamin A liver stores. Further, advanced HIV disease is likely to increase the risk of MTCT, and hence it would appear that low serum vitamin A levels are associated with increased MTCT. The HIV genome also has a retinoic acid receptor element-hence, vitamin A may increase HIV replication via interacting with this element, thus increasing risk of MTCT. Finally, vitamin A is known to

When interacting with categories, representations focused on within-category relationships are often learned, but the conditions promoting within-category representations and their generalizability are unclear. We report the results of three experiments investigating the impact of category structure and training methodology on the learning and generalization of within-category representations (i.e., correlational structure). Participants were trained on either rule-based or information-integration structures using classification (Is the stimulus a member of Category A or Category B?), concept (e.g., Is the stimulus a member of Category A, Yes or No?), or inference (infer the missing component of the stimulus from a given category) and then tested on either an inference task (Experiments 1 and 2) or a classification task (Experiment 3). For the information-integration structure, within-category representations were consistently learned, could be generalized to novel stimuli, and could be generalized to support inference at test. For the rule-based structure, extended inference training resulted in generalization to novel stimuli (Experiment 2) and inference training resulted in generalization to classification (Experiment 3). These data help to clarify the conditions under which within-category representations can be learned. Moreover, these results make an important contribution in highlighting the impact of category structure and training methodology on the generalization of categorical knowledge.

The influence of category coherence on inference about cross-classified entities.

PubMed

Patalano, Andrea L; Wengrovitz, Steven M; Sharpes, Kirsten M

2009-01-01

A critical function of categories is their use in property inference (Heit, 2000). However, one challenge to using categories in inference is that most entities in the world belong to multiple categories (e.g., Fido could be a dog, a pet, a mammal, or a security system). Building on Patalano, Chin-Parker, and Ross (2006), we tested the hypothesis that category coherence (the extent to which category features go together in light of prior knowledge) influences the selection of categories for use in property inference about cross-classified entities. In two experiments, we directly contrasted coherent and incoherent categories, both of which included cross-classified entities as members, and we found that the coherent categories were used more readily as the source of both property transfer and property extension. We conclude that category coherence, which has been found to be a potent influence on strength of inference for singly classified entities (Rehder & Hastie, 2004), is also central to category use in reasoning about novel cross-classified ones.

2008-12-01

The objective of this study conducted among women with AIDS, was to identify the knowledge about how they acquired the disease, as well as the meaning AIDS has in their Quality of Life. This is a qualitative, exploratory descriptive study encompassing twelve women. The data were collected through semi-structured interviews from October 2006 to January 2007. After the analysis, two categories were identified. The first one related to how AIDS was acquired, and the other to the meanings of Quality of Life (QL) for these women. The results revealed that the interviewees know how the HIV infection was acquired. The meanings, as far as Quality of Life, had to do with keeping healthy, family and work relationships, and acceptance of current situation, all of which points out to the need of providing wholesome care for these women.

Perceiving expatriate coworkers as foreigners encourages aid: social categorization and procedural justice together improve intergroup cooperation and dual identity.

PubMed

Leonardelli, Geoffrey J; Toh, Soo Min

2011-01-01

We propose that social categorization can encourage particular forms of intergroup cooperation because it differentiates a group in need from a group that can give aid. Moreover, social categorization is most likely to occur when individuals perceive procedural justice (i.e., fair treatment) from authorities in a superordinate group that includes the individuals' subgroup. Two field studies investigating relations between local and foreign coworkers tested not only this prediction, but also whether high social categorization and procedural justice would yield a dual identity, in which group members identify simultaneously with their social category and the superordinate group. Both studies supported our predictions: Local employees engaged a dual identity and offered knowledge to aid a foreign coworker's adjustment more often when local-foreign categorization and procedural justice from organizational authorities were high than when these variables were low. These discoveries point to controllable mechanisms that enable intergroup cooperation, and our findings have important implications for intergroup aid, expatriate adjustment, immigration, and multiculturalism.

The Role of Corticostriatal Systems in Speech Category Learning

2016-01-01

One of the most difficult category learning problems for humans is learning nonnative speech categories. While feedback-based category training can enhance speech learning, the mechanisms underlying these benefits are unclear. In this functional magnetic resonance imaging study, we investigated neural and computational mechanisms underlying feedback-dependent speech category learning in adults. Positive feedback activated a large corticostriatal network including the dorsolateral prefrontal cortex, inferior parietal lobule, middle temporal gyrus, caudate, putamen, and the ventral striatum. Successful learning was contingent upon the activity of domain-general category learning systems: the fast-learning reflective system, involving the dorsolateral prefrontal cortex that develops and tests explicit rules based on the feedback content, and the slow-learning reflexive system, involving the putamen in which the stimuli are implicitly associated with category responses based on the reward value in feedback. Computational modeling of response strategies revealed significant use of reflective strategies early in training and greater use of reflexive strategies later in training. Reflexive strategy use was associated with increased activation in the putamen. Our results demonstrate a critical role for the reflexive corticostriatal learning system as a function of response strategy and proficiency during speech category learning.

The Equal Employment Opportunity Commission (EEOC) has been successful in resolving discrimination cases that involve HIV/AIDS. Half of the cases the EEOC has taken to court under the Americans with Disabilities Act (ADA) have been settled out of court. Over 900 claims of disability-based employment discrimination related to HIV/AIDS have been brought to the EEOC since the ADA took effect in 1992. AIDS is the largest single category of disability that has been sent to court directly by the EEOC. By filing suit, the EEOC reminds employers that they cannot fire a worker with a disability or cap an employee's medical benefits to improve corporate profit margin.

A new zero-inflated negative binomial methodology for latent category identification.

Blanchard, Simon J; DeSarbo, Wayne S

2013-04-01

We introduce a new statistical procedure for the identification of unobserved categories that vary between individuals and in which objects may span multiple categories. This procedure can be used to analyze data from a proposed sorting task in which individuals may simultaneously assign objects to multiple piles. The results of a synthetic example and a consumer psychology study involving categories of restaurant brands illustrate how the application of the proposed methodology to the new sorting task can account for a variety of categorization phenomena including multiple category memberships and for heterogeneity through individual differences in the saliency of latent category structures.

Encoding tasks dissociate the effects of divided attention on category-cued recall and category-exemplar generation.

PubMed

Parker, Andrew; Dagnall, Neil; Munley, Gary

2012-01-01

The combined effects of encoding tasks and divided attention upon category-exemplar generation and category-cued recall were examined. Participants were presented with pairs of words each comprising a category name and potential example of that category. They were then asked to indicate either (i) their liking for both of the words or (ii) if the exemplar was a member of the category. It was found that divided attention reduced performance on the category-cued recall task under both encoding conditions. However, performance on the category-exemplar generation task remained invariant across the attention manipulation following the category judgment task. This provides further evidence that the processes underlying performance on conceptual explicit and implicit memory tasks can be dissociated, and that the intentional formation of category-exemplar associations attenuates the effects of divided attention on category-exemplar generation.

Culture, category salience, and inductive reasoning.

PubMed

Choi, I; Nisbett, R E; Smith, E E

1997-12-01

The role of category salience in category-based induction was demonstrated in two ways: (i) temporarily increasing category salience facilitated category-based induction, and (ii) this effect was moderated by cultural differences that we predicted would be related to chronic category salience. Subjects for whom categories were presumed to be more accessible (Americans) were not as much influenced by manipulations to increase category salience as subjects who were presumed to have lower chronic accessibility of categories (Koreans). However, as anticipated, this pattern was reversed for inferences about behavioral properties of social categories. Due to the 'interdependent' nature of their culture, Koreans presumably have relatively higher chronic accessibility for social categories than do relatively 'independent' Americans, and hence were not influenced as much by increasing category salience.

Traditional beliefs about the cause of AIDS and AIDS-related stigma in South Africa.

PubMed

Kalichman, S C; Simbayi, L

2004-07-01

AIDS-related stigmas are pervasive in some segments of South African society and stigmas can impede efforts to promote voluntary counselling and testing and other HIV-AIDS prevention efforts. The current study examined associations among the belief that AIDS is caused by spirits and supernatural forces, AIDS-related knowledge and AIDS-related stigmas. A street intercept survey with 487 men and women living in a Black township in Cape Town, South Africa showed that 11% (n=54) believed that AIDS is caused by spirits and supernatural forces, 21% (n=105) were unsure if AIDS is caused by spirits and the supernatural, and 68% (n=355) did not believe that AIDS is caused by spirits and supernatural forces. Multiple logistic regression analyses controlling for participant age, gender, years of education and survey venue showed that people who believed HIV-AIDS is caused by spirits and the supernatural demonstrated significantly more misinformation about AIDS and were significantly more likely to endorse repulsion and social sanction stigmatizing beliefs against people living with HIV-AIDS. However, nearly all associations between beliefs that AIDS is caused by spirits and AIDS stigmas were non-significant when logistic regressions were repeated with AIDS-related knowledge included as a control variable. This finding suggests that relationships between traditional beliefs about the cause of HIV-AIDS and AIDS stigmas are mediated by AIDS-related knowledge. AIDS education efforts are urgently needed to reach people who hold traditional beliefs about AIDS to remedy AIDS stigmas.

How much do parents know about first aid for burns?

2013-09-01

Prompt first aid reduces burn morbidity. With an estimated 19,000 children attending emergency departments (ED) with a burn or scald every year in the UK, a parent's knowledge of first aid is particularly important. This study evaluates the extent and source of this knowledge. Parents attending the emergency and antenatal departments of a University Hospital answered a structured questionnaire detailing demographics, knowledge of burns first aid and its source. Knowledge was stratified into 4 categories: contraindicated, poor, inadequate and adequate. Individual chi-squared tests and ordered logistic regressions were performed to relate knowledge to demographic features. The 106 respondents (44% men) reflected a wide range of socio-economic (SE) grouping and educational level. Overall 32% had an adequate knowledge of burns first aid while 43% had poor or no knowledge. There was no significant correlation between gender, educational status or age and knowledge; however those from higher SE groups (p<0.05) and those who had undergone first aid training (p<0.01) had greater knowledge. Among 40% of parents who had undergone first aid training, 74% had adequate knowledge. The logistic regression accounting for all significant variables showed that previous first aid training was the most influential factor in knowledge of first aid (p<0.001). Interestingly, although 2/3 of parents wanted further training, 75% of those who did not had poor or no first-aid knowledge. Overall, the knowledge of burns first aid among parents is inadequate and correlates with lower SE groups. There was a significant association between knowledge and previous first aid training. Results suggest that targeting burns first aid training to all new parents, particularly those in low income households, would be of value. Copyright © 2013 Elsevier Ltd and ISBI.

not busy with activities that could be assigned to others. Our study sample included only of manager nurses, who were responsible of nursing offices in ASLs which included outpatients. facilities on the whole territory ofl Italy. We choose to make a convenience sampling, choosing a manager nurse for each regional chief town. Our study is an observational, non-experimental quantitative research. To collect our data we used an anonymous questionnaire, based on a reference model, which had already been used in older studies. The model allowed a classification of the tasks performed by nurses in three categories: Nursing activities without chances of delegation; Nursing activities that could be assigned to aids; Activities beyond the competence of nurses. The questionnaire was articulated in 7 categories (general situation, booking, acceptation, preparation of patients' units, nursing care, tasks usually performed in outpatients' services, rearrangement of patients' units). We made a comparison between our data and the reference model. In the studied outpatients' services, nurses take in charge a high percentage of tasks (39%) that should be performed by others. More precisely, there are activities that should be carried out by aids (17%) or employees (22%). For example, in the category "Rearrangement of the patient's units", nurses perform approximately 70% of the tasks. Our study revealed that not employing aids at their fullest affects the problem; overall, our data show that 45% of nurses' everyday working time could be regained, if it were possible to assign to aids and employees all the activities that are not nurses' competence. This would produce a series of positive consequences, such as bringing out of the competences acquired by nurses, a better qualification and a real identification of the contribution given by nurses to the citizenship, other than an adequate employment and usage of human resources.

Study preferences for exemplar variability in self-regulated category learning.

PubMed

Wahlheim, Christopher N; DeSoto, K Andrew

2017-02-01

Increasing exemplar variability during category learning can enhance classification of novel exemplars from studied categories. Four experiments examined whether participants preferred variability when making study choices with the goal of later classifying novel exemplars. In Experiments 1-3, participants were familiarised with exemplars of birds from multiple categories prior to making category-level assessments of learning and subsequent choices about whether to receive more variability or repetitions of exemplars during study. After study, participants classified novel exemplars from studied categories. The majority of participants showed a consistent preference for variability in their study, but choices were not related to category-level assessments of learning. Experiment 4 provided evidence that study preferences were based primarily on theoretical beliefs in that most participants indicated a preference for variability on questionnaires that did not include prior experience with exemplars. Potential directions for theoretical development and applications to education are discussed.

Understanding emotion is critical for a science of healthy and disordered brain function, but the neurophysiological basis of emotional experience is still poorly understood. We analyzed human brain activity patterns from 148 studies of emotion categories (2159 total participants) using a novel hierarchical Bayesian model. The model allowed us to classify which of five categories—fear, anger, disgust, sadness, or happiness—is engaged by a study with 66% accuracy (43-86% across categories). Analyses of the activity patterns encoded in the model revealed that each emotion category is associated with unique, prototypical patterns of activity across multiple brain systems including the cortex, thalamus, amygdala, and other structures. The results indicate that emotion categories are not contained within any one region or system, but are represented as configurations across multiple brain networks. The model provides a precise summary of the prototypical patterns for each emotion category, and demonstrates that a sufficient characterization of emotion categories relies on (a) differential patterns of involvement in neocortical systems that differ between humans and other species, and (b) distinctive patterns of cortical-subcortical interactions. Thus, these findings are incompatible with several contemporary theories of emotion, including those that emphasize emotion-dedicated brain systems and those that propose emotion is localized primarily in subcortical activity. They are consistent with componential and constructionist views, which propose that emotions are differentiated by a combination of perceptual, mnemonic, prospective, and motivational elements. Such brain-based models of emotion provide a foundation for new translational and clinical approaches. PMID:25853490

Decoding the neural representation of fine-grained conceptual categories.

2016-05-15

Neuroscientific research on conceptual knowledge based on the grounded cognition framework has shed light on the organization of concrete concepts into semantic categories that rely on different types of experiential information. Abstract concepts have traditionally been investigated as an undifferentiated whole, and have only recently been addressed in a grounded cognition perspective. The present fMRI study investigated the involvement of brain systems coding for experiential information in the conceptual processing of fine-grained semantic categories along the abstract-concrete continuum. These categories consisted of mental state-, emotion-, mathematics-, mouth action-, hand action-, and leg action-related meanings. Thirty-five sentences for each category were used as stimuli in a 1-back task performed by 36 healthy participants. A univariate analysis failed to reveal category-specific activations. Multivariate pattern analyses, in turn, revealed that fMRI data contained sufficient information to disentangle all six fine-grained semantic categories across participants. However, the category-specific activity patterns showed no overlap with the regions coding for experiential information. These findings demonstrate the possibility of detecting specific patterns of neural representation associated with the processing of fine-grained conceptual categories, crucially including abstract ones, though bearing no anatomical correspondence with regions coding for experiential information as predicted by the grounded cognition hypothesis.

This study aimed to compare the effectiveness of tinnitus retraining therapy (TRT) with sound generators or with open ear hearing aids in the rehabilitation of tinnitus for a group of subjects who, according to Jastreboff categories, can be treated with both approaches to sound therapy (borderline of Category 1 and 2). This study was a prospective data collection with a parallel-group design which entailed that each subject was randomly assigned to one of the two treatments group: half of the subjects were fitted binaurally with sound generators, and the other half with open ear hearing aids. Both groups received the same educational counselling sessions. Ninety-one subjects passed the screening criteria and were enrolled into the study. Structured interviews, with a variety of measures evaluated through the use of visual-analog scales and the tinnitus handicap inventory self-administered questionnaire, were performed before the therapy and at 3, 6, and 12 months during the therapy. Data showed a highly significant improvement in both tinnitus treatments starting from the first three months and up to one year of therapy, with a progressive and statistically significant decrease in the disability every three months. TRT was equally effective with sound generator or open ear hearing aids: they gave basically identical, statistically indistinguishable results.

Operator vision aids for space teleoperation assembly and servicing

1992-01-01

This paper investigates concepts for visual operator aids required for effective telerobotic control. Operator visual aids, as defined here, mean any operational enhancement that improves man-machine control through the visual system. These concepts were derived as part of a study of vision issues for space teleoperation. Extensive literature on teleoperation, robotics, and human factors was surveyed to definitively specify appropriate requirements. This paper presents these visual aids in three general categories of camera/lighting functions, display enhancements, and operator cues. In the area of camera/lighting functions concepts are discussed for: (1) automatic end effector or task tracking; (2) novel camera designs; (3) computer-generated virtual camera views; (4) computer assisted camera/lighting placement; and (5) voice control. In the technology area of display aids, concepts are presented for: (1) zone displays, such as imminent collision or indexing limits; (2) predictive displays for temporal and spatial location; (3) stimulus-response reconciliation displays; (4) graphical display of depth cues such as 2-D symbolic depth, virtual views, and perspective depth; and (5) view enhancements through image processing and symbolic representations. Finally, operator visual cues (e.g., targets) that help identify size, distance, shape, orientation and location are discussed.

In Study 1 (N= 230), we found that the participants' explicit prejudice was not related to their knowledge of cultural stereotypes of immigrants in Sweden, and that they associated the social category immigrants with the same national/ethnic categories. In Study 2 (N= 88), employing the category and stereotype words obtained in Study 1 as primes, we examined whether participants with varying degrees of explicit prejudice differed in their automatic stereotyping and implicit prejudice when primed with category or stereotypical words. In accord with our hypothesis, and contrary to previous findings, the results showed that people's explicit prejudice did not affect their automatic stereotyping and implicit prejudice, neither in the category nor stereotype priming condition. Study 3 (N= 62), employing category priming using facial photographs of Swedes and immigrants as primes, showed that participants' implicit prejudice was not moderated by their explicit prejudice. The outcome is discussed in relation to the distinction between category and stereotype priming and in terms of the associative strength between a social category and its related stereotypes.

Category Learning in the Brain

PubMed Central

Seger, Carol A.; Miller, Earl K.

2013-01-01

The ability to group items and events into functional categories is a fundamental characteristic of sophisticated thought. It is subserved by plasticity in many neural systems, including neocortical regions (sensory, prefrontal, parietal, and motor cortex), the medial temporal lobe, the basal ganglia, and midbrain dopaminergic systems. These systems interact during category learning. Corticostriatal loops may mediate recursive, bootstrapping interactions between fast reward-gated plasticity in the basal ganglia and slow reward-shaded plasticity in the cortex. This can provide a balance between acquisition of details of experiences and generalization across them. Interactions between the corticostriatal loops can integrate perceptual, response, and feedback-related aspects of the task and mediate the shift from novice to skilled performance. The basal ganglia and medial temporal lobe interact competitively or cooperatively, depending on the demands of the learning task. PMID:20572771

Adjacent-Categories Mokken Models for Rater-Mediated Assessments

PubMed Central

Wind, Stefanie A.

2016-01-01

Molenaar extended Mokken’s original probabilistic-nonparametric scaling models for use with polytomous data. These polytomous extensions of Mokken’s original scaling procedure have facilitated the use of Mokken scale analysis as an approach to exploring fundamental measurement properties across a variety of domains in which polytomous ratings are used, including rater-mediated educational assessments. Because their underlying item step response functions (i.e., category response functions) are defined using cumulative probabilities, polytomous Mokken models can be classified as cumulative models based on the classifications of polytomous item response theory models proposed by several scholars. In order to permit a closer conceptual alignment with educational performance assessments, this study presents an adjacent-categories variation on the polytomous monotone homogeneity and double monotonicity models. Data from a large-scale rater-mediated writing assessment are used to illustrate the adjacent-categories approach, and results are compared with the original formulations. Major findings suggest that the adjacent-categories models provide additional diagnostic information related to individual raters’ use of rating scale categories that is not observed under the original formulation. Implications are discussed in terms of methods for evaluating rating quality. PMID:29795916

"We talk of AIDS because we love life": a stakeholder assessment of HIV/AIDS organizations in Buenos Aires, Argentina.

PubMed

Spaulding, Alicen B; Brieger, William R

This stakeholder assessment of HIV/AIDS service providing institutions in Argentina offers insights into the HIV/AIDS crisis in Spanish-speaking Latin America from an institutional level and makes recommendations for strengthening the work and functioning of these institutions. This stakeholder assessment was conducted to determine how HIV/AIDS prevention and management in Argentina affects and is affected by relevant HIV/AIDS institutions. Semi-structured qualitative interviews were conducted with 13 key leaders of organizations working in HIV/AIDS prevention in Buenos Aires including non-governmental, governmental, and academic institutions. Analyses of interviewee comments are presented according to four major themes: network connections, program resources, perceptions of success, and challenges. Key findings include the need for strengthening formal networks, increasing the involvement of other non-AIDS related social institutions in promoting HIV prevention, finding more sustainable funding options, working more effectively with the public sector to create policies and regulations favorable to the HIV/AIDS field, and addressing the lack of perceived susceptibility to HIV/AIDS in Argentine culture. From leaders' comments, recommendations are made for strengthening the HIV/AIDS network among key institutions including adapting the UNAIDS "Three Ones" principal to create one crosssector office responsible for coordinating HIV/AIDS work, formalizing agreements with institutions outside of Buenos Aires, increasing the role of schools in HIV/AIDS awareness, and designing programs that address lack of perceived susceptibility to HIV/AIDS among Argentines.

To examine the experiences of caregiving among Vietnamese family members of persons living with HIV/AIDS. As the number of persons living with HIV/AIDS increases, the need of family caregivers who can take responsibility for the home care of these persons increases. Vietnam has one of the fastest growing HIV epidemics in Asia. A descriptive cross-sectional study with quantitative and qualitative methods was used. A purposive sample of 104 family caregivers, both male and female, participated voluntarily by answering a questionnaire of caregiver burden, and 20 of them participated in in-depth interview. Female caregivers were mainly mothers and wives while male caregivers were mainly husbands, fathers and siblings. The largest group of family caregivers reported moderate to severe burden. There was no difference between genders in total caregiver burden, but there were several differences between older and younger caregivers in some items of caregiver burden. Five categories of experiences emerged: Different types of caregiving to persons living with HIV/AIDS, cultural and religious issues associated with caregiving, keeping secret to avoid stigma and discrimination, lack of knowledge about disease and provision of care, and fear, anxiety and frustration. Stigma and discrimination should be decreased by providing knowledge to the general public about HIV/AIDS, in particular about ways of transmission and protection. Special knowledge should be given to family caregivers to enable them to give care to persons living with HIV/AIDS at home. This could be done through culturally appropriate training/intervention programmes in which coping methods should be included. Support group interventions should also be carried through. The results obtained can be used as baseline information. Health care providers should consider gender, age and culture of family members of persons living with HIV/AIDS. Knowledge about HIV/AIDS, provision of care at home and in hospital, and

Category identification of changed land-use polygons in an integrated image processing/geographic information system

A framework is proposed for analyzing ancillary data and developing procedures for incorporating ancillary data to aid interactive identification of land-use categories in land-use updates. The procedures were developed for use within an integrated image processsing/geographic information systems (GIS) that permits simultaneous display of digital image data with the vector land-use data to be updated. With such systems and procedures, automated techniques are integrated with visual-based manual interpretation to exploit the capabilities of both. The procedural framework developed was applied as part of a case study to update a portion of the land-use layer in a regional scale GIS. About 75 percent of the area in the study site that experienced a change in land use was correctly labeled into 19 categories using the combination of automated and visual interpretation procedures developed in the study.

Decentralisation is defined as the dispersion, distribution or transfer of resources, functions and decision-making power from a central authority to regional and local authorities. It is usually accompanied by assignment of accountability and responsibility for results. Fundamental to understanding decentralisation is learning what motivates central governments to give up power and resources to local governments, and the practical significance of this on their positions regarding decentralisation. This study examined key political and institutional influences on role-players' capacity to support decentralisation of HIV and AIDS treatment services to primary healthcare facilities, and implications for sustainability. In-depth interviews were conducted with 55 purposively selected key informants, drawn from three Nigerian states that were at different stages of decentralising HIV and AIDS treatment services to primary care facilities. Key informants represented different categories of role-players involved in HIV and AIDS control programmes. Thematic framework analysis of data was done. Support for decentralisation of HIV and AIDS treatment services to primary healthcare facilities was substantial among different categories of actors. Political factors such as the local and global agenda for health, political tenure and party affiliations, and institutional factors such as consolidation of decision-making power and improvements in career trajectories, influenced role-players support for decentralisation of HIV and AIDS treatment services. It is feasible and acceptable to decentralise HIV and AIDS treatment services to primary healthcare facilities, to help improve coverage. However, role-players' support largely depends on how well the reform aligns with political structures and current institutional practices.

A Feature-Reinforcement-Based Approach for Supporting Poly-Lingual Category Integration

NASA Astrophysics Data System (ADS)

Wei, Chih-Ping; Chen, Chao-Chi; Cheng, Tsang-Hsiang; Yang, Christopher C.

Document-category integration (or category integration for short) is fundamental to many e-commerce applications, including information integration along supply chains and information aggregation by intermediaries. Because of the trend of globalization, the requirement for category integration has been extended from monolingual to poly-lingual settings. Poly-lingual category integration (PLCI) aims to integrate two document catalogs, each of which consists of documents written in a mix of languages. Several category integration techniques have been proposed in the literature, but these techniques focus only on monolingual category integration rather than PLCI. In this study, we propose a feature-reinforcement-based PLCI (namely, FR-PLCI) technique that takes into account the master documents of all languages when integrating source documents (in the source catalog) written in a specific language into the master catalog. Using the monolingual category integration (MnCI) technique as a performance benchmark, our empirical evaluation results show that our proposed FR-PLCI technique achieves better integration accuracy than MnCI does in both English and Chinese category integration tasks.

Survival After HIV Infection Stage 3 (AIDS) Diagnosis, by Population Density Areas, United States, 2005-2010.

PubMed

Bosh, Karin A; Shi, Jing; Chen, Mi

We examined the survival rates after diagnosis of HIV infection stage 3 (AIDS) in the United States by population density area of residence at diagnosis. We used data from the National HIV Surveillance System to calculate survival rates among people aged ≥13 with HIV infection stage 3 (AIDS) diagnosed from 2005 through 2010. We determined survival rates for more than 12, 24, and 36 months after diagnosis; overall and by demographic characteristics; and across 3 population density area categories (large metropolitan statistical areas [MSAs, ≥500 000 people], small-to-medium MSAs [50 000 to 499 999 people], and nonmetropolitan areas [<50 000 people]). The survival rates for more than 12, 24, and 36 months after diagnosis were highest among people residing in large MSAs (90.2%, 87.2%, and 84.9%, respectively) and lowest among people residing in nonmetropolitan areas (87.3%, 84.1%, and 81.4%, respectively). With a few exceptions, survival rates were lower in those residing in nonmetropolitan areas than those residing in large MSAs and small-to-medium MSAs across most subgroups by age at diagnosis, race/ethnicity, sex, transmission category, region of residence, and year of diagnosis. Between 2005 and 2010, significant year-to-year increases occurred in the proportion of people surviving more than 36 months after diagnosis across all 3 population density area categories (estimated annual percentage change: large MSAs [0.88; 95% confidence interval (CI), 0.56-1.20]; small-to-medium MSAs [0.94; 95% CI, 0.06-1.83]; and nonmetropolitan areas [1.26; 95% CI, 0.07-2.46]). Although survival rates for those with HIV infection stage 3 (AIDS) improved in all 3 population density area categories, efforts to remove barriers to care and promote treatment adherence in nonmetropolitan areas will be necessary to eliminate survival disparities.

Treatment of category generation and retrieval in aphasia: Effect of typicality of category items.

Purpose: Kiran and colleagues (Kiran, 2007, 2008; Kiran & Johnson, 2008; Kiran & Thompson, 2003) have previously suggested that training atypical examples within a semantic category is a more efficient treatment approach to facilitating generalization within the category than training typical examples. The present study extended our previous work examining the notion of semantic complexity within goal-derived (ad-hoc) categories in individuals with aphasia. Methods: Six individuals with fluent aphasia (range = 39-84 years) and varying degrees of naming deficits and semantic impairments were involved. Thirty typical and atypical items each from two categories were selected after an extensive stimulus norming task. Generative naming for the two categories was tested during baseline and treatment. Results: As predicted, training atypical examples in the category resulted in generalization to untrained typical examples in five out the five patient-treatment conditions. In contrast, training typical examples (which was in examined three conditions) produced mixed results. One patient showed generalization to untrained atypical examples, whereas two patients did not show generalization to untrained atypical examples. Conclusions: Results of the present study supplement our existing data on the effect of a semantically based treatment for lexical retrieval by manipulating the typicality of category exemplars.

Conceptual influences on category-based induction

PubMed Central

Gelman, Susan A.; Davidson, Natalie S.

2013-01-01

One important function of categories is to permit rich inductive inferences. Prior work shows that children use category labels to guide their inductive inferences. However, there are competing theories to explain this phenomenon, differing in the roles attributed to conceptual information versus perceptual similarity. Seven experiments with 4- to 5-year-old children and adults (N = 344) test these theories by teaching categories for which category membership and perceptual similarity are in conflict, and varying the conceptual basis of the novel categories. Results indicate that for non-natural kind categories that have little conceptual coherence, children make inferences based on perceptual similarity, whereas adults make inferences based on category membership. In contrast, for basic- and ontological-level categories that have a principled conceptual basis, children and adults alike make use of category membership more than perceptual similarity as the basis of their inferences. These findings provide evidence in favor of the role of conceptual information in preschoolers’ inferences, and further demonstrate that labeled categories are not all equivalent; they differ in their inductive potential.

2013-02-01

The South African communities has shown to have a challenge in accessing health services especially in rural areas; hence the national strategic objective 1.7 aimed at strengthening community systems to expand access to services using the community-based care programmes (NSP 2012-2016). The programmes enhance access to health services whilst promoting health and educating the community to improve health knowledge and work towards attaining a healthy living (NSP 2012-2016). However, the health promoters from the rural Hammanskraal region in the North West Province of South Africa often found themselves rendering the health promotion services in their communities with limited resources. This study aimed at exploring and describing the challenges faced by health promoters in implementing health promotion programmes for families with adolescents orphaned by HIV and AIDS. The study followed a qualitative design. Data was collected using focus group interviews. Participants were purposely selected by the social worker and the health promotion coordinator working at Hammanskraal. The process of data analysis was adapted from the eight steps of Tesch method of data analysis where categories, sub-categories and themes were isolated. The following categories emerged as the needs of health promoters on health promotion programmes for families with adolescents orphaned by HIV and AIDS, (1) financial needs, (2) resources, (3) basic life needs, (4) educational needs and (5) health promoter's needs. It is therefore recommended that equal distribution of resources: including medicine, equipment and finances, should be maintained in order to ensure non-interrupted services.

Ego depletion interferes with rule-defined category learning but not non-rule-defined category learning.

PubMed

Minda, John P; Rabi, Rahel

2015-01-01

Considerable research on category learning has suggested that many cognitive and environmental factors can have a differential effect on the learning of rule-defined (RD) categories as opposed to the learning of non-rule-defined (NRD) categories. Prior research has also suggested that ego depletion can temporarily reduce the capacity for executive functioning and cognitive flexibility. The present study examined whether temporarily reducing participants' executive functioning via a resource depletion manipulation would differentially impact RD and NRD category learning. Participants were either asked to write a story with no restrictions (the control condition), or without using two common letters (the ego depletion condition). Participants were then asked to learn either a set of RD categories or a set of NRD categories. Resource depleted participants performed more poorly than controls on the RD task, but did not differ from controls on the NRD task, suggesting that self regulatory resources are required for successful RD category learning. These results lend support to multiple systems theories and clarify the role of self-regulatory resources within this theory.

Color categories only affect post-perceptual processes when same- and different-category colors are equally discriminable.

PubMed

He, Xun; Witzel, Christoph; Forder, Lewis; Clifford, Alexandra; Franklin, Anna

2014-04-01

Prior claims that color categories affect color perception are confounded by inequalities in the color space used to equate same- and different-category colors. Here, we equate same- and different-category colors in the number of just-noticeable differences, and measure event-related potentials (ERPs) to these colors on a visual oddball task to establish if color categories affect perceptual or post-perceptual stages of processing. Category effects were found from 200 ms after color presentation, only in ERP components that reflect post-perceptual processes (e.g., N2, P3). The findings suggest that color categories affect post-perceptual processing, but do not affect the perceptual representation of color.

Impact of feature saliency on visual category learning.

PubMed

Hammer, Rubi

2015-01-01

People have to sort numerous objects into a large number of meaningful categories while operating in varying contexts. This requires identifying the visual features that best predict the 'essence' of objects (e.g., edibility), rather than categorizing objects based on the most salient features in a given context. To gain this capacity, visual category learning (VCL) relies on multiple cognitive processes. These may include unsupervised statistical learning, that requires observing multiple objects for learning the statistics of their features. Other learning processes enable incorporating different sources of supervisory information, alongside the visual features of the categorized objects, from which the categorical relations between few objects can be deduced. These deductions enable inferring that objects from the same category may differ from one another in some high-saliency feature dimensions, whereas lower-saliency feature dimensions can best differentiate objects from distinct categories. Here I illustrate how feature saliency affects VCL, by also discussing kinds of supervisory information enabling reflective categorization. Arguably, principles debated here are often being ignored in categorization studies.

An overview of computational modelling of the impact of AIDS on business in South Africa, with a detailed description of the AIDS Projection Model (APM) for companies, developed by the author, and suggestions for further work. Computational modelling of the impact of AIDS on business in South Africa requires modelling of the epidemic as a whole, and of its impact on a company. This paper gives an overview of epidemiological modelling, with an introduction to the Actuarial Society of South Africa (ASSA) model, the most widely used such model for South Africa. The APM produces projections of HIV prevalence, new infections, and AIDS mortality on a company, based on the anonymous HIV testing of company employees, and projections from the ASSA model. A smoothed statistical model of the prevalence test data is computed, and then the ASSA model projection for each category of employees is adjusted so that it matches the measured prevalence in the year of testing. FURTHER WORK: Further techniques that could be developed are microsimulation (representing individuals in the computer), scenario planning for testing strategies, and models for the business environment, such as models of entire sectors, and mapping of HIV prevalence in time and space, based on workplace and community data.

The composition of category conjunctions.

Hutter, Russell R C; Crisp, Richard J

2005-05-01

In three experiments, the authors investigated the impression formation process resulting from the perception of familiar or unfamiliar social category combinations. In Experiment 1, participants were asked to generate attributes associated with either a familiar or unfamiliar social category conjunction. Compared to familiar combinations, the authors found that when the conjunction was unfamiliar, participants formed their impression less from the individual constituent categories and relatively more from novel emergent attributes. In Experiment 2, the authors replicated this effect using alternative experimental materials. In Experiment 3, the effect generalized to additional (orthogonally combined) gender and occupation categories. The implications of these findings for understanding the processes involved in the conjunction of social categories, and the formation of new stereotypes, are discussed.

1991-01-01

This article considers the epidemic proportion of AIDS in developing countries, and discusses the U.S. Agency for International Development's (USAID) reworked and intensified strategy for HIV infection and AIDS prevention and control over the next 5 years. Developing and launching over 650 HIV and AIDS activities in 74 developing countries since 1986, USAID is the world's largest supporter of anti-AIDS programs. Over $91 million in bilateral assistance for HIV and AIDS prevention and control have been committed. USAID has also been the largest supporter of the World Health Organization's Global Program on AIDS since 1986. Interventions have included training peer educators, working to change the norms of sex behavior, and condom promotion. Recognizing that the developing world will increasingly account for an ever larger share of the world's HIV-infected population, USAID announced an intensified program of estimated investment increasing to approximately $400 million over a 5-year period. Strategy include funding for long-term, intensive interventions in 10-15 priority countries, emphasizing the treatment of other sexually transmitted diseases which facilitate the spread of HIV, making AIDS-related policy dialogue an explicit component of the Agency's AIDS program, and augmenting funding to community-based programs aimed at reducing high-risk sexual behaviors. The effect of AIDS upon child survival, adult mortality, urban populations, and socioeconomic development in developing countries is discussed. Program examples are also presented.

To be able to fulfil high market expectations for a number of practical applications, Environmental Product Declarations (EPDs) have to meet and comply with specific and strict methodological prerequisites. These expectations include the possibility to add up Life Cycle Assessment (LCA)-based information in the supply chain and to compare different EPDs. To achieve this goal, common and harmonized calculation rules have to be established, the so-called Product Category Rules (PCRs), which set the overall LCA calculation rules to create EPDs. This document provides PCRs for the assessment of the environmental performance of canned anchovies in Cantabria Region based on an Environmental Sustainability Assessment (ESA) method. This method uses two main variables: the natural resources sustainability (NRS) and the environmental burdens sustainability (EBS). To reduce the complexity of ESA and facilitate the decision-making process, all variables are normalized and weighted to obtain two global dimensionless indexes: resource consumption (X 1 ) and environmental burdens (X 2 ). •This paper sets the PCRs adapted to the Cantabrian canned anchovies.•ESA method facilitates the product comparison and the decision-making process.•This paper stablishes all the steps that an EPD should include within the PCRs of Cantabrian canned anchovies.

The First Aid Manual constitutes a detailed guide which contains useful information and suggested acts for potential pathogenic conditions in everyday life, given in an Android environment. The aim of the project is the capability of eliciting information regarding First Aid, by means of a widespread use device, such as smartphones. For the conduction of the project a database was used, into which the information was incorporated, in order to be later reloaded into the Eclipse environment. It will there receive its final form as an executable file for android cellphones. The executable file axx.apk originated an application which, providing the user with 6 main categories (definition, epidemiological evidence, aggravating factors, symptoms, what to do, what to avoid, acts) gives them access to an easy navigation and enables them to provide first grade care, without the requirement of any previous experience. The more and more advanced needs of the modern lifestyle, combined with technological achievements have created a complex system of social fabric, having of course an effect also on the area of human accidents. Hence, First Aid information given in the environment of a mobile phone can prove to be a useful tool for anyone, in case of an accident.

Simplicial Descent Categories

NASA Astrophysics Data System (ADS)

Rodriguez Gonzalez, Beatriz

2008-04-01

Much of the homotopical and homological structure of the categories of chain complexes and topological spaces can be deduced from the existence and properties of the 'simple' functors Tot : {double chain complexes} -> {chain complexes} and geometric realization : {sSets} -> {Top}, or similarly, Tot : {simplicial chain complexes} -> {chain complexes} and | | : {sTop} -> {Top}. The purpose of this thesis is to abstract this situation, and to this end we introduce the notion of '(co)simplicial descent category'. It is inspired by Guillen-Navarros's '(cubical) descent categories'. The key ingredients in a (co)simplicial descent category D are a class E of morphisms in D, called equivalences, and a 'simple' functor s : {(co)simplicial objects in D} -> D. They must satisfy axioms like 'Eilenberg-Zilber', 'exactness' and 'acyclicity'. This notion covers a wide class of examples, as chain complexes, sSets, topological spaces, filtered cochain complexes (where E = filtered quasi-isomorphisms or E = E_2-isomorphisms), commutative differential graded algebras (with s = Navarro's Thom-Whitney simple), DG-modules over a DG-category and mixed Hodge complexes, where s = Deligne's simple. From the simplicial descent structure we obtain homotopical structure on D, as cone and cylinder objects. We use them to i) explicitly describe the morphisms of HoD=D[E^{-1}] similarly to the case of calculus of fractions; ii) endow HoD with a non-additive pre-triangulated structure, that becomes triangulated in the stable additive case. These results use the properties of a 'total functor', which associates to any biaugmented bisimplicial object a simplicial object. It is the simplicial analogue of the total chain complex of a double complex, and it is left adjoint to Illusie's 'decalage' functor.

Learning about the internal structure of categories through classification and feature inference.

PubMed

Jee, Benjamin D; Wiley, Jennifer

2014-01-01

Previous research on category learning has found that classification tasks produce representations that are skewed toward diagnostic feature dimensions, whereas feature inference tasks lead to richer representations of within-category structure. Yet, prior studies often measure category knowledge through tasks that involve identifying only the typical features of a category. This neglects an important aspect of a category's internal structure: how typical and atypical features are distributed within a category. The present experiments tested the hypothesis that inference learning results in richer knowledge of internal category structure than classification learning. We introduced several new measures to probe learners' representations of within-category structure. Experiment 1 found that participants in the inference condition learned and used a wider range of feature dimensions than classification learners. Classification learners, however, were more sensitive to the presence of atypical features within categories. Experiment 2 provided converging evidence that classification learners were more likely to incorporate atypical features into their representations. Inference learners were less likely to encode atypical category features, even in a "partial inference" condition that focused learners' attention on the feature dimensions relevant to classification. Overall, these results are contrary to the hypothesis that inference learning produces superior knowledge of within-category structure. Although inference learning promoted representations that included a broad range of category-typical features, classification learning promoted greater sensitivity to the distribution of typical and atypical features within categories.

To propose nonparametric ensemble machine learning for mental health and substance use disorders (MHSUD) spending risk adjustment formulas, including considering Clinical Classification Software (CCS) categories as diagnostic covariates over the commonly used Hierarchical Condition Category (HCC) system. 2012-2013 Truven MarketScan database. We implement 21 algorithms to predict MHSUD spending, as well as a weighted combination of these algorithms called super learning. The algorithm collection included seven unique algorithms that were supplied with three differing sets of MHSUD-related predictors alongside demographic covariates: HCC, CCS, and HCC + CCS diagnostic variables. Performance was evaluated based on cross-validated R 2 and predictive ratios. Results show that super learning had the best performance based on both metrics. The top single algorithm was random forests, which improved on ordinary least squares regression by 10 percent with respect to relative efficiency. CCS categories-based formulas were generally more predictive of MHSUD spending compared to HCC-based formulas. Literature supports the potential benefit of implementing a separate MHSUD spending risk adjustment formula. Our results suggest there is an incentive to explore machine learning for MHSUD-specific risk adjustment, as well as considering CCS categories over HCCs. © Health Research and Educational Trust.

First aid encompasses a wide range of scenarios ranging from simple reassurance following a minor mishap to dealing with a life-threatening emergency. Dentists may need to provide first aid in their dental practice to a patient, relative or member of staff. This article provides an overview to first aid in the dental practice, including priorities, responsibilities when providing first aid, assessment of the environment and the casualty (primary survey &secondary survey). The new A3 'First Aid in the Workplace' poster is now available and is included as an insert in this issue (BDJ Vol. 220, Issue 12).

Models as Relational Categories

NASA Astrophysics Data System (ADS)

Kokkonen, Tommi

2017-11-01

Model-based learning (MBL) has an established position within science education. It has been found to enhance conceptual understanding and provide a way for engaging students in authentic scientific activity. Despite ample research, few studies have examined the cognitive processes regarding learning scientific concepts within MBL. On the other hand, recent research within cognitive science has examined the learning of so-called relational categories. Relational categories are categories whose membership is determined on the basis of the common relational structure. In this theoretical paper, I argue that viewing models as relational categories provides a well-motivated cognitive basis for MBL. I discuss the different roles of models and modeling within MBL (using ready-made models, constructive modeling, and generative modeling) and discern the related cognitive aspects brought forward by the reinterpretation of models as relational categories. I will argue that relational knowledge is vital in learning novel models and in the transfer of learning. Moreover, relational knowledge underlies the coherent, hierarchical knowledge of experts. Lastly, I will examine how the format of external representations may affect the learning of models and the relevant relations. The nature of the learning mechanisms underlying students' mental representations of models is an interesting open question to be examined. Furthermore, the ways in which the expert-like knowledge develops and how to best support it is in need of more research. The discussion and conceptualization of models as relational categories allows discerning students' mental representations of models in terms of evolving relational structures in greater detail than previously done.

Categorial Compositionality: A Category Theory Explanation for the Systematicity of Human Cognition

PubMed Central

Phillips, Steven; Wilson, William H.

2010-01-01

Classical and Connectionist theories of cognitive architecture seek to explain systematicity (i.e., the property of human cognition whereby cognitive capacity comes in groups of related behaviours) as a consequence of syntactically and functionally compositional representations, respectively. However, both theories depend on ad hoc assumptions to exclude specific instances of these forms of compositionality (e.g. grammars, networks) that do not account for systematicity. By analogy with the Ptolemaic (i.e. geocentric) theory of planetary motion, although either theory can be made to be consistent with the data, both nonetheless fail to fully explain it. Category theory, a branch of mathematics, provides an alternative explanation based on the formal concept of adjunction, which relates a pair of structure-preserving maps, called functors. A functor generalizes the notion of a map between representational states to include a map between state transformations (or processes). In a formal sense, systematicity is a necessary consequence of a higher-order theory of cognitive architecture, in contrast to the first-order theories derived from Classicism or Connectionism. Category theory offers a re-conceptualization for cognitive science, analogous to the one that Copernicus provided for astronomy, where representational states are no longer the center of the cognitive universe—replaced by the relationships between the maps that transform them.

[Late diagnosis and vulnerabilities of the elderly living with HIV/AIDS].

Alencar, Rúbia Aguiar; Ciosak, Suely Itsuko

2015-04-01

To identify vulnerabilities of elderly people with HIV/AIDS and the trajectory that they follow until reaching the diagnosis of the disease. Qualitative research conducted in specialized clinics in the state of São Paulo, from January to June 2011. Semi-structured interviews were conducted with 11 elderly people who were found to be infected with the virus at the age of 60 years or older. The interviews were analyzed using content analysis. In this process four categories emerged, then analyzed with reference to the theoretical framework of vulnerability. Late diagnosis of HIV infection or AIDS among the elderly happens in the secondary or tertiary service. Issues related to sexual life of the elderly are only questioned by health professionals after the diagnosis, also the time that condom use becomes absolute. It is believed that the investigation of the vulnerability of the elderly to HIV/AIDS allows for carrying out appropriate interventions for this population.

Families, children, migration and AIDS.

PubMed

Haour-Knipe, Mary

2009-01-01

Migration is very often a family affair, and often involves children, directly or indirectly. It may give rise to better quality of life for an entire family, or to bitter disappointment, and may also increase vulnerability to HIV and AIDS. This review, carried out for the Joint Learning Initiative on Children and AIDS, links the literature on "migration", on "HIV and AIDS" and on "families". Three themes are sketched: (1) As both HIV prevalence and circular migration increase, former migrant workers affected by AIDS may return to their families for care and support, especially at the end of life, often under crisis conditions. Families thus lose promising members, as well as sources of support. However, very little is known about the children of such migrants. (2) Following patterns of migration established for far different reasons, children may have to relocate to different places, sometimes over long distances, if their AIDS-affected parents can no longer care for them. They face the same adaptation challenges as other children who move, but complicated by loss of parent(s), AIDS stigma, and often poverty. (3) The issue of migrant families living with HIV has been studied to some extent, but mainly in developed countries with a long history of migration, and with little attention paid to the children in such families. Difficulties include involuntary separation from family members, isolation and lack of support, disclosure and planning for children's care should the parent(s) die and differences in treatment access within the same family. Numerous research and policy gaps are defined regarding the three themes, and a call is made for thinking about migration, families and AIDS to go beyond description to include resilience theory, and to go beyond prevention to include care.

Making the connections: AIDS and water.

PubMed

Ball, Anna-Marie

2006-01-01

Acknowledging AIDS as a crosscutting development issue, a Zambian rural water supply project that provides safe accessible water to rural communities embarked on a new initiative to mainstream AIDS into the water sector. The work of providing safe water takes the predominantly male workforce away from their spouses and families, into the rural villages of Zambia's Eastern Province, for long periods of time. With an HIV prevalence rate of 16.1%, the risk of HIV exposure exists for both employees and rural villagers. AIDS mainstreaming activities were designed to target both groups. An AIDS mainstreaming strategy was developed by identifying components that could be influenced in the external domain (the organization's usual work) and the internal domain (the workplace). Basic questions were addressed such as: how does AIDS affect the organization, how might the usual work aggravate susceptibility to HIV infection, and where is the comparative advantage? A workplace program including peer education, employee health education (including condoms) and a workplace policy was established for employees. For the target population, a series of five messages connecting safe water and AIDS was developed and disseminated through educational drama, community meetings and trainings, and integrated into the regular water, sanitation and hygiene activities. As an efficient utilization of resources that makes a broad impact, AIDS mainstreaming does not change the sector's mandate but takes advantage of the extensive geographic coverage and natural distribution system of water projects to disseminate AIDS information and make linkages with AIDS partners.

The objective of this study is to determine the frequency of clinically significant cancer (CSC) in Prostate Imaging Reporting and Data System (PI-RADS) category 3 (equivocal) lesions prospectively identified on multiparametric prostate MRI and to identify risk factors (RFs) for CSC that may aid in decision making. Between January 2015 and July 2016, a total of 977 consecutively seen men underwent multiparametric prostate MRI, and 342 underwent MRI-ultrasound (US) fusion targeted biopsy. A total of 474 lesions were retrospectively reviewed, and 111 were scored as PI-RADS category 3 and were visualized using a 3-T MRI scanner. Multiparametric prostate MR images were prospectively interpreted by body subspecialty radiologists trained to use PI-RADS version 2. CSC was defined as a Gleason score of at least 7 on targeted biopsy. A multivariate logistic regression model was constructed to identify the RFs associated with CSC. Of the 111 PI-RADS category 3 lesions, 81 (73.0%) were benign, 11 (9.9%) were clinically insignificant (Gleason score, 6), and 19 (17.1%) were clinically significant. On multivariate analysis, three RFs were identified as significant predictors of CSC: older patient age (odds ratio [OR], 1.13; p = 0.002), smaller prostate volume (OR, 0.94; p = 0.008), and abnormal digital rectal examination (DRE) findings (OR, 3.92; p = 0.03). For PI-RADS category 3 lesions associated with zero, one, two, or three RFs, the risk of CSC was 4%, 16%, 62%, and 100%, respectively. PI-RADS category 3 lesions for which two or more RFs were noted (e.g., age ≥ 70 years, gland size ≤ 36 mL, or abnormal DRE findings) had a CSC detection rate of 67% with a sensitivity of 53%, a specificity of 95%, a positive predictive value of 67%, and a negative predictive value of 91%. Incorporating clinical parameters into risk stratification algorithms may improve the ability to detect clinically significant disease among PI-RADS category 3 lesions and may aid in the decision to

How to develop a company AIDS policy.

Bompey, S H

1986-07-01

It is for most businesses only a matter of time before they will have experience with Acquired Immune Deficiency Syndrome (AIDS), and the experience could be very costly for companies which fail to implement an effective AIDS policy. Potential AIDS problems include: antidiscrimination suits based on firing or failing to hire an individual who had AIDS or carries the AIDS virus antibodies; defamation suits from employees who are wrongly identified; disability claims that do not fit the pattern for other diseases; civil rights penalties in some situations when AIDS victims are prevented from working; and run-ins with the Occupational Safety and Health Administration or the National Labor Relations Board if healthy workers refuse to work alongside AIDS victims. A company needs to think through its AIDS policy, but that does not mean establishing a "special" AIDS policy which may create paranoia among employees. The best approach is to develop a health policy that includes all catastrophic illnesses, not just AIDS. There have been few court decisions involving AIDS because AIDS is a recent illness, victims often do not live long enough to pursue the matter, and it often pays to settle AIDS cases out of court. Employers need to know that judges, administrative agencies, and arbitrators take the position that AIDS is a disability. As such, AIDS is treated under the anti-handicap discrimination laws on the books of most states. Additionally, the Federal Rehabilitation Act of 1973 prohibits discrimination against the disabled by companies that contract with the federal government or receive federal financial assistance. It usually is illegal to discriminate against the disabled workers, and in some states against workers who are perceived to have a disability. The best defense against the fear of working alongside and AIDs sufferer is education.

Data categories for marine planning

The U.S. National Ocean Policy calls for a science- and ecosystem-based approach to comprehensive planning and management of human activities and their impacts on America’s oceans. The Ocean Community in Data.gov is an outcome of 2010–2011 work by an interagency working group charged with designing a national information management system to support ocean planning. Within the working group, a smaller team developed a list of the data categories specifically relevant to marine planning. This set of categories is an important consensus statement of the breadth of information types required for ocean planning from a national, multidisciplinary perspective. Although the categories were described in a working document in 2011, they have not yet been fully implemented explicitly in online services or geospatial metadata, in part because authoritative definitions were not created formally. This document describes the purpose of the data categories, provides definitions, and identifies relations among the categories and between the categories and external standards. It is intended to be used by ocean data providers, managers, and users in order to provide a transparent and consistent framework for organizing and describing complex information about marine ecosystems and their connections to humans.

2009-10-19

Development and testing of a decision aid about prevention of myocardial infarction for persons with type 2 diabetes. Development and testing were guided by the UK Medical Research Council's guidance for the development and evaluation of complex interventions. This comprised a systematic literature review, a focus group of 9 potential providers, modelling a prototype, interviews to qualitatively explore understanding and additional information needs, and revision of the decision aid. The decision aid includes evidence-based information, a tool for individual risk-assessment, worksheets, and an action plan. Five diabetes educators and 15 patients underwent two 60-minutes face-to-face interviews, firstly browsing the decision aid for the first time and then after using it. Both groups differed in their ratings. Overall, the decision aid was rated to present essential information in a complex but understandable and unbiased manner. Difficulties involved understanding of terminology and risk interpretation. "Social status as a risk factor" was the most challenged content by educators but considered as highly important by patients. The risk assessment tool was used inadequately. 5 patients allocated themselves into false risk categories. After revision of the tool, all 12 patients who were recruited for reassessment used the tool correctly. The decision aid was evaluated with diabetes educators and patients. Qualitative data analysis revealed aspects for revision. The decision aid is planned to be part of a shared decision making programme, comprising a strategy for patient counselling and educational modules addressed to providers. Quantitative evaluation is required to assess its effectiveness.

This article is a systhematic literature review including the period from 1994 to 2009, whose objective was to discuss the aged woman's vulnerability in relation to Acquired Imunodeficiency Syndrome (Aids). The search for scientific texts was accomplished in the following databases: Biblioteca Virtual em Saúde, Scientific Eletronic Library Online (SciELO), Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) and Medical Literature Analysis and Retrieval System Online (MEDLINE). The descriptors used were vulnerability, woman and Aids. Eighteen texts were analyzed, including articles in scientific journals, thesis and dissertations. As a conclusion, it was noted that aged women and vulnerability to Aids are directly related, through gender characteristics including submission and that were built historical and socially. We consider as fundamental the development of studies which may generate publications accessible to women, in order to help them see themselves as persons vulnerable to Aids contagion just for being women.

Perceptual Influence of Ugandan Biology Students' Understanding of HIV/AIDS

NASA Astrophysics Data System (ADS)

Mutonyi, Harriet; Nashon, Samson; Nielsen, Wendy S.

2010-08-01

In Uganda, curbing the spread of HIV/AIDS has largely depended on public and private media messages about the disease. Media campaigns based on Uganda’s cultural norms of communication are metaphorical, analogical and simile-like. The topic of HIV/AIDS has been introduced into the Senior Three (Grade 11) biology curriculum in Uganda. To what extent do students’ pre-conceptions of the disease, based on these media messages influence students’ development of conceptual understanding of the disease, its transmission and prevention? Of significant importance is the impact the conceptions students have developed from the indirect media messages on classroom instruction on HIV/AIDS. The study is based in a theoretical framework of conceptual change in science learning. An interpretive case study to determine the impact of Ugandan students’ conceptions or perceptions on classroom instruction about HIV/AIDS, involving 160 students aged 15-17, was conducted in four different Ugandan high schools: girls boarding, boys boarding, mixed boarding, and mixed day. Using questionnaires, focus group discussions, recorded biology lessons and informal interviews, students’ preconceptions of HIV/AIDS and how these impact lessons on HIV/AIDS were discerned. These preconceptions fall into four main categories: religious, political, conspiracy and traditional African worldviews. Results of data analysis suggest that students’ prior knowledge is persistent even after biology instructions. This has implications for current teaching approaches, which are mostly teacher-centred in Ugandan schools. A rethinking of the curriculum with the intent of offering science education programs that promote understanding of the science of HIV/AIDS as opposed to what is happening now—insensitivity to misconceptions about the disease—is needed.

Determining Nurse Aide Staffing Requirements to Provide Care Based on Resident Workload: A Discrete Event Simulation Model.

PubMed

Schnelle, John F; Schroyer, L Dale; Saraf, Avantika A; Simmons, Sandra F

2016-11-01

Nursing aides provide most of the labor-intensive activities of daily living (ADL) care to nursing home (NH) residents. Currently, most NHs do not determine nurse aide staffing requirements based on the time to provide ADL care for their unique resident population. The lack of an objective method to determine nurse aide staffing requirements suggests that many NHs could be understaffed in their capacity to provide consistent ADL care to all residents in need. Discrete event simulation (DES) mathematically models key work parameters (eg, time to provide an episode of care and available staff) to predict the ability of the work setting to provide care over time and offers an objective method to determine nurse aide staffing needs in NHs. This study had 2 primary objectives: (1) to describe the relationship between ADL workload and the level of nurse aide staffing reported by NHs; and, (2) to use a DES model to determine the relationship between ADL workload and nurse aide staffing necessary for consistent, timely ADL care. Minimum Data Set data related to the level of dependency on staff for ADL care for residents in over 13,500 NHs nationwide were converted into 7 workload categories that captured 98% of all residents. In addition, data related to the time to provide care for the ADLs within each workload category was used to calculate a workload score for each facility. The correlation between workload and reported nurse aide staffing levels was calculated to determine the association between staffing reported by NHs and workload. Simulations to project staffing requirements necessary to provide ADL care were then conducted for 65 different workload scenarios, which included 13 different nurse aide staffing levels (ranging from 1.6 to 4.0 total hours per resident day) and 5 different workload percentiles (ranging from the 5th to the 95th percentile). The purpose of the simulation model was to determine the staffing necessary to provide care within each workload

2014-06-01

The aim of this study was to know the meanings attributed by female health professionals to the process of caring for women with HIV, considering their vulnerability in the context of feminization of HIV/AIDS. It is a qualitative study based on the grounded theory method and symbolic interactionism, conducted in two public maternity hospitals in Rio de Janeiro, from November 2009 to April 2010. Data were collected by means of semi-structured interviews with twelve female health professionals. The core category that emerged was "Speaking as a Professional and Thinking about Caring" which focused on the meaning of care, and the integration of two categories, the first being the concerns of being a woman/professional caring for women with HIV and the second being the meanings of professional care provided to women with the virus. It was concluded that the professionals still maintained the former perception of HIV/AIDS, contributing to increased gender vulnerability to HIV, discrimination and prejudice.

The Advisory Council of the American Red Cross Disaster Services requested that an independent study determine whether first-aid providers without professional mental health training, when confronted with people who have experienced a traumatic event, offer a "safe, effective and feasible intervention." Standard databases were searched by an expert panel from 1990 to September 2010 using the keyword phrase "psychological first aid." Documents were included if the process was referred to as care provided to victims, first responders, or volunteers and excluded if it was not associated with a disaster or mass casualty event, or was used after individual nondisaster traumas such as rape and murder. This search yielded 58 citations. It was determined that adequate scientific evidence for psychological first aid is lacking but widely supported by expert opinion and rational conjecture. No controlled studies were found. There is insufficient evidence supporting a treatment standard or a treatment guideline. Sufficient evidence for psychological first aid is widely supported by available objective observations and expert opinion and best fits the category of "evidence informed" but without proof of effectiveness. An intervention provided by volunteers without professional mental health training for people who have experienced a traumatic event offers an acceptable option. Further outcome research is recommended.

2012-06-01

Patients want to be more involved in medical decision-making. To this end, some decision aids are now available. We present an overview of this subject, in which we explain the terms "shared decision-making", "decision aid", and "evidence-based patient information" and survey information on the available decision aids in German and other languages on the basis of a literature search in MEDLINE, EMBASE and PsycInfo and a current Cochrane Review. We also searched the Internet for providers of decision aids in Germany. Decision aids exist in the form of brochures, decision tables, videos, and computer programs; they address various topics in the prevention, diagnosis, and treatment of disease. They typically contain information on the advantages and disadvantages of the available options, as well as guidance for personal decision-making. They can be used alone or as a part of structured counseling or patient education. Minimal quality standards include an adequate evidence base, completeness, absence of bias, and intelligibility. Our search revealed 12 randomized controlled trials (RCTs) of decision aids in German and 106 RCTs of decision aids in other languages. These trials studied the outcome of the use of decision aids not just with respect to clinical developments, but also with respect to patient knowledge, adherence to treatment regimens, satisfaction, involvement in decision-making, autonomy preference, and decisional conflicts. Only a small fraction of the available decision aids were systematically developed and have been subjected to systematic evaluation. Patients are still not receiving the help in decision-making to which medical ethics entitles them. Structures need to be put in place for the sustainable development, evaluation and implementation of high-quality decision aids.

In South Africa, the HIV&AIDS education policy documents indicate opportunities for integration across disciplines/subjects. There are different interpretations of integration/inclusion and mainstreaming HIV&AIDS education, and numerous levels of integration. Integration ensures that learners experience the disciplines/subjects as being linked and related, and integration is required to support and expand the learners' opportunities to attain skills, acquire knowledge and develop attitudes and values across the curriculum. This study makes use of self-study methodology where I, a teacher educator, aim to improve my practice through including HIV&AIDS statistics in Mathematics Education. This article focuses on how I used HIV&AIDS statistics to facilitate pre-service teacher reflection and introduce them to integration of HIV&AIDS education across the curriculum. After pre-service teachers were provided with HIV statistics, they drew a pie chart which graphically illustrated the situation and reflected on issues relating to HIV&AIDS. Three themes emerged from the analysis of their reflections. The themes relate to the need for further HIV&AIDS education, the changing pastoral role of teachers and the changing context of teaching. This information indicates that the use of statistics is an appropriate means of initiating the integration of HIV&AIDS education into the academic curriculum.

Incremental Bayesian Category Learning From Natural Language.

Frermann, Lea; Lapata, Mirella

2016-08-01

Models of category learning have been extensively studied in cognitive science and primarily tested on perceptual abstractions or artificial stimuli. In this paper, we focus on categories acquired from natural language stimuli, that is, words (e.g., chair is a member of the furniture category). We present a Bayesian model that, unlike previous work, learns both categories and their features in a single process. We model category induction as two interrelated subproblems: (a) the acquisition of features that discriminate among categories, and (b) the grouping of concepts into categories based on those features. Our model learns categories incrementally using particle filters, a sequential Monte Carlo method commonly used for approximate probabilistic inference that sequentially integrates newly observed data and can be viewed as a plausible mechanism for human learning. Experimental results show that our incremental learner obtains meaningful categories which yield a closer fit to behavioral data compared to related models while at the same time acquiring features which characterize the learned categories.

Rose, M A

1996-01-01

The purpose of this study was to examine the effect of an age-specific AIDS education program on HIV/AIDS knowledge, perceived susceptibility to AIDS, and perceived severity of AIDS in older adults. The health belief model served as a framework. The age-specific AIDS education program was developed based on a knowledge, beliefs, and behaviors survey of 458 older adults at senior citizen centers. The program included case study presentations of actual older people with AIDS along with an emphasis on myths identified in the initial survey. There was a significant increase in total knowledge about AIDS (p < .001), perceived susceptibility (p < .01), and perceived severity (p < .001) after the educational program. Based on the results of this study, nurses are in an excellent position to provide primary and secondary AIDS prevention strategies for all age groups, including the older adult population.

With regard to hearing perception, it remains unclear as to whether, or the extent to which, different conceptual categories of real-world sounds and related categorical knowledge are differentially represented in the brain. Semantic knowledge representations are reported to include the major divisions of living versus non-living things, plus more specific categories including animals, tools, biological motion, faces, and places—categories typically defined by their characteristic visual features. Here, we used functional magnetic resonance imaging (fMRI) to identify brain regions showing preferential activity to four categories of action sounds, which included non-vocal human and animal actions (living), plus mechanical and environmental sound-producing actions (non-living). The results showed a striking antero-posterior division in cortical representations for sounds produced by living versus non-living sources. Additionally, there were several significant differences by category, depending on whether the task was category-specific (e.g. human or not) versus non-specific (detect end-of-sound). In general, (1) human-produced sounds yielded robust activation in the bilateral posterior superior temporal sulci independent of task. Task demands modulated activation of left-lateralized fronto-parietal regions, bilateral insular cortices, and subcortical regions previously implicated in observation-execution matching, consistent with “embodied” and mirror-neuron network representations subserving recognition. (2) Animal action sounds preferentially activated the bilateral posterior insulae. (3) Mechanical sounds activated the anterior superior temporal gyri and parahippocampal cortices. (4) Environmental sounds preferentially activated dorsal occipital and medial parietal cortices. Overall, this multi-level dissociation of networks for preferentially representing distinct sound-source categories provides novel support for grounded cognition models that may

Word meaning processing in the brain involves ventrolateral temporal cortex, but a semantic contribution of the dorsal stream, especially frontocentral sensorimotor areas, has been controversial. We here examine brain activation during passive reading of object-related nouns from different semantic categories, notably animal, food, and tool words, matched for a range of psycholinguistic features. Results show ventral stream activation in temporal cortex along with category-specific activation patterns in both ventral and dorsal streams, including sensorimotor systems and adjacent pFC. Precentral activation reflected action-related semantic features of the word categories. Cortical regions implicated in mouth and face movements were sparked by food words, and hand area activation was seen for tool words, consistent with the actions implicated by the objects the words are used to speak about. Furthermore, tool words specifically activated the right cerebellum, and food words activated the left orbito-frontal and fusiform areas. We discuss our results in the context of category-specific semantic deficits in the processing of words and concepts, along with previous neuroimaging research, and conclude that specific dorsal and ventral areas in frontocentral and temporal cortex index visual and affective-emotional semantic attributes of object-related nouns and action-related affordances of their referent objects.

Right away: A late, right-lateralized category effect complements an early, left-lateralized category effect in visual search.

PubMed

Constable, Merryn D; Becker, Stefanie I

2017-10-01

According to the Sapir-Whorf hypothesis, learned semantic categories can influence early perceptual processes. A central finding in support of this view is the lateralized category effect-namely, the finding that categorically different colors (e.g., blue and green hues) can be discriminated faster than colors within the same color category (e.g., different hues of green), especially when they are presented in the right visual field. Because the right visual field projects to the left hemisphere, this finding has been popularly couched in terms of the left-lateralization of language. However, other studies have reported bilateral category effects, which has led some researchers to question the linguistic origins of the effect. Here we examined the time course of lateralized and bilateral category effects in the classical visual search paradigm by means of eyetracking and RT distribution analyses. Our results show a bilateral category effect in the manual responses, which is combined of an early, left-lateralized category effect and a later, right-lateralized category effect. The newly discovered late, right-lateralized category effect occurred only when observers had difficulty locating the target, indicating a specialization of the right hemisphere to find categorically different targets after an initial error. The finding that early and late stages of visual search show different lateralized category effects can explain a wide range of previously discrepant findings.

The helpfulness of category labels in semi-supervised learning depends on category structure.

2016-02-01

The study of semi-supervised category learning has generally focused on how additional unlabeled information with given labeled information might benefit category learning. The literature is also somewhat contradictory, sometimes appearing to show a benefit to unlabeled information and sometimes not. In this paper, we frame the problem differently, focusing on when labels might be helpful to a learner who has access to lots of unlabeled information. Using an unconstrained free-sorting categorization experiment, we show that labels are useful to participants only when the category structure is ambiguous and that people's responses are driven by the specific set of labels they see. We present an extension of Anderson's Rational Model of Categorization that captures this effect.

To investigate the significance of the time from seroconversion to AIDS (incubation time) and other covariates for survival from AIDS to death. In survival analysis, survival from AIDS to death was compared for different categories of length of incubation time adjusted and unadjusted for other covariates, and significant predictors for survival from AIDS to death were investigated. Survival after AIDS was not affected by the incubation time in univariate as well as in multivariate analyses. Predictive factors for progression from AIDS to death were age at seroconversion, type of AIDS diagnosis, and CD4 cell count at AIDS. The relative hazard for age at seroconversion increased 1.38-fold over 10 years. Men with a CD4 cell count at AIDS of <130 x 10(6)/l had a twofold higher risk in progression to death than men with higher CD4 cell counts. Persons diagnosed with lymphoma had a sixfold higher risk of progression to death than persons with Kaposi's sarcoma or opportunistic infections. The incubation time as well as other factors before AIDS did not affect survival after AIDS. Survival from AIDS to death can be predicted by data obtained at the time of AIDS diagnosis, such as type of diagnosis, age and CD4 cell count. AIDS seems to be a significant point in progression to death, and not just a floating point between infection and death affected by prior factors for persons who did not receive effective therapy and did not have long incubation times.

HIV / AIDS and tourism.

PubMed

Forsythe, S

1999-01-01

Since it tends to be significantly affected by HIV/AIDS, the tourism sector is a likely target for HIV/AIDS interventions in many countries. The tourist industry is at particular risk from the pandemic because of the mobility of the work force, the presence of sex tourists, and the heavy reliance of many countries upon tourism revenues. Indeed, tourism is one of the largest and fastest growing industries in many countries. Some people have speculated that potential tourists' fear of AIDS could discourage them from visiting certain countries, while others have even suggested that tourism should be discouraged because the industry contributes to the spread of HIV/AIDS. When traveling, tourists often take risks that they would not take at home. They tend to drink more, use drugs more, and be generally more adventurous while on holiday. Such adventures often include taking sexual risks. When tourists have sex with prostitutes, hotel staff, and others in the local population, a bridge can be created for HIV to cross back and forth between the tourist's home country and the tourist destination. The author reviews selected studies on the relationship between HIV/AIDS and tourism. Overall, the existing literature offers no definitive evidence that AIDS has had any lasting impact upon the tourism industry anywhere in the world. Rather, promoting a healthy tourism industry and HIV/AIDS prevention are likely complementary in many ways.

The semi-structured interview was used to collect data from January to August 2012. this research presents the category: Nurses' perceptions of the vulnerabilities to STD/AIDS in light of the process of adolescence, and the subcategories: Risks and uncertainties of the process of adolescence: paths to STD/AIDS; Age-adolescence complex: expanding knowledge from the perception of nurses. once the nurses understand the complexity of adolescence, they create strategies to reduce the vulnerability of adolescents to STD/AIDS. This signals the need to invest in education, assistance and the management of nursing care for adolescents.

Using BIRADS categories in ROC experiments

This paper investigated the use of the Breast Imaging Reporting And Data System (BIRADS) Lexicon in ROC mammography experiments. Analysis was based on data from parallel ROC experiments performed at two Institutions with different readers and databases to compare film to digitized mammography. Seven readers participated in the studies and read approximately 200 cases each in two formats: film and digital or softcopy. Reporting was done using BIRADS categories 1 through 5. Training was done with a separate set of cases and included detailed review of the relationship between BIRADS and a standard ROC discrete 5-point rating scale. The results from both sites showed equivalency between film and softcopy mammography. Decisions using the BIRADS categories showed no unsampled ROC regions and no degenerate data. Fits yielded smooth ROC curves that correlated to clinical practice. In a qualitative evaluation, all observers indicated preference in using the BIRADS classes instead of a discrete or continuous rating scheme. Familiarity with the rating process seems to relieve some of the bias associated with the interpretation of digitized mammograms from computer monitors (softcopy reading). Our results suggested that BIRADS categories can be used in comparative ROC studies because they represent a scale familiar to the reader that can be followed consistently and they provide a rating approach that accounts for both positive and negative cases to be evaluated and categorized.

Predictors of Hearing-Aid Outcomes

Over 360 million people worldwide suffer from disabling hearing loss. Most of them can be treated with hearing aids. Unfortunately, performance with hearing aids and the benefit obtained from using them vary widely across users. Here, we investigate the reasons for such variability. Sixty-eight hearing-aid users or candidates were fitted bilaterally with nonlinear hearing aids using standard procedures. Treatment outcome was assessed by measuring aided speech intelligibility in a time-reversed two-talker background and self-reported improvement in hearing ability. Statistical predictive models of these outcomes were obtained using linear combinations of 19 predictors, including demographic and audiological data, indicators of cochlear mechanical dysfunction and auditory temporal processing skills, hearing-aid settings, working memory capacity, and pretreatment self-perceived hearing ability. Aided intelligibility tended to be better for younger hearing-aid users with good unaided intelligibility in quiet and with good temporal processing abilities. Intelligibility tended to improve by increasing amplification for low-intensity sounds and by using more linear amplification for high-intensity sounds. Self-reported improvement in hearing ability was hard to predict but tended to be smaller for users with better working memory capacity. Indicators of cochlear mechanical dysfunction, alone or in combination with hearing settings, did not affect outcome predictions. The results may be useful for improving hearing aids and setting patients’ expectations. PMID:28929903

Anthropometric Profile in Different Event Categories of Acrobatic Gymnastics

2017-01-01

Abstract There is a specific anthropometric profile for each sport, which may be differentiated even in relation to the position, role or event category within each sport discipline. However, there are few studies on acrobatic gymnastics, and the goal of this work was to determine the anthropometric profile depending on the event category, as well as factors that predisposed to performance in these categories. The sample consisted of 150 gymnasts from Spain, divided into 8 groups according to the event category and the role played. The kinanthropometric measurements were taken through the procedures established by the International Society for the Advancement of Kineantropometry. The anthropometric characteristics, including body mass index, somatotype, body composition and proportionality using the Phantom stratagem were analyzed, and the results obtained from the different groups were compared. A regression analysis was performed with particular groups of gymnasts. No significant differences (p < 0.05) were observed between groups of female tops or male bases, although differences were found between female group bases and female pair bases. It could be suggested that higher values of body height, sitting height, the minimum abdominal circumference, percentage of fat and low biliocristal breadth predispose female bases to work in pairs rather than in groups. The conclusion is that the anthropometric measurements are not decisive when guiding a gymnast toward choosing one event category or another, except for female bases. PMID:28713469

We assessed the relationship between the size of the 39 Journal Citation Reports (JCR) medical categories and impact factor (IF) of journals in these categories, and the implications that it might have for emergency medicine (EM) journals. Using the 2010 JCR database, we calculated the mean IF, 5-year IF (5y-IF), Eigenfactor (EF), and Article Influence (AI) scores including all journals for each category. We also calculated a 'weighted IF' for all journals by dividing each journal IF by the mean IF of its category. We ranked EM journals according to IF and 'weighted IF' into all the journals included in the 39 categories. We assessed the relationship between category size and bibliometric scores by linear regression. Category size varied from 252 journals (Pharmacology and Pharmacy) to 14 (Primary Healthcare), EM category occupying the 36th position (23 journals). The mean IF of EM category ranked in 34th position, 5-yIF in 32nd, EF in 34th, and AI in 34th position. Category size had a direct and significant association with mean IF, 5y-IF, and AI but not with mean EF. When the EM journals were ranked among all the journals according to their IF, only two (9%) were placed into the first quartile and raised up to eight (35%) when 'weighted IF' was considered. There is a negative relationship between JCR size category and IF achieved by the journals. This places EM journals at a clear disadvantage because they represent one of the smallest clinical medical research disciplines.

The impact of immunosuppression despite virological suppression (immuno-virological discordance, ID) on the risk of developing fatal and non-fatal AIDS/non-AIDS events is unclear and remains to be elucidated. Patients in EuroSIDA starting at least 1 new antiretroviral drug with CD4<350 cells/µl and viral load (VL)>500 copies/mL were followed-up from the first day of VL< = 50 copies/ml until a new fatal/non-fatal non-AIDS/AIDS event. Considered non-AIDS events included non-AIDS malignancies, pancreatitis, severe liver disease with hepatic encephalopathy (>grade 3), cardio- and cerebrovascular events, and end-stage renal disease. Patients were classified over time according to whether current CD4 count was above (non-ID) or below (ID) baseline level. Relative rates (RR) of events were calculated for ID vs. non-ID using adjusted Poisson regression models. 2,913 patients contributed 11,491 person-years for the analysis of non-AIDS. 241 pre-specified non-AIDS events (including 84 deaths) and 89 AIDS events (including 10 deaths) occurred. The RR of developing pre-specified non-AIDS events for ID vs. non-ID was 1.96 (95% CI 1.37-2.81, p<0.001) in unadjusted analysis and 1.43 (0.94-2.17, p = 0.095) after controlling for current CD4 count. ID was not associated with the risk of AIDS events (aRR 0.76, 95% CI 0.41-1.38, p = 0.361). Compared to CD4 responders, patients with immuno-virological discordance may be at increased risk of developing non-AIDS events. Further studies are warranted to establish whether in patients with ID, strategies to directly modify CD4 count response may be needed besides the use of ART.

Developing a method to derive alcohol-attributable fractions for HIV/AIDS mortality based on alcohol's impact on adherence to antiretroviral medication

PubMed Central

2011-01-01

Background Alcohol consumption is causally linked to nonadherence to antiretroviral treatment that in turn causes an increase in HIV/AIDS mortality. This article presents a method to calculate the percentage of HIV/AIDS deaths attributable to alcohol consumption and the associated uncertainty. Methods By combining information on risk relations from a number of published sources, we estimated alcohol-attributable fractions (AAFs) of HIV/AIDS in a stepwise procedure. First, we estimated the effect of alcohol consumption on adherence to antiretroviral treatment, and then we combined this estimate with the impact of nonadherence on death. The 95% uncertainty intervals were computed by estimating the variance of the AAFs using Taylor series expansions of one and multiple variables. AAFs were determined for each of the five Global Burden of Disease regions of Africa, based on country-specific treatment and alcohol consumption data from 2005. Results The effects of alcohol on HIV/AIDS in the African Global Burden of Disease regions range from 0.03% to 0.34% for men and from 0% to 0.17% for women, depending on region and age category. The detrimental effect of alcohol consumption was statistically significant in every region and age category except for the North Africa/Middle East region. Conclusions Although the method has its limitations, it was shown to be feasible and provided estimates of the impact of alcohol use on the mortality outcome of HIV/AIDS. PMID:21320310

The 'end of AIDS' project: Mobilising evidence, bureaucracy, and big data for a final biomedical triumph over AIDS.

Leclerc-Madlala, Suzanne; Broomhall, Lorie; Fieno, John

2017-12-04

Efforts are currently underway by major orchestrators and funders of the global AIDS response to realise the vision of achieving an end to AIDS by 2030. Unlike previous efforts to provide policy guidance or to encourage 'best practice' approaches for combatting AIDS, the end of AIDS project involves the promotion of a clear set of targets, tools, and interventions for a final biomedical solution to the epidemic. In this paper, we examine the bureaucratic procedures of one major AIDS funder that helped to foster a common vision and mission amongst a global AIDS community with widely divergent views on how best to address the epidemic. We focus on the methods, movements, and materials that are central to the project of ending AIDS, including those related to biomedical forms of evidence and big data science. We argue that these approaches have limitations and social scientists need to pay close attention to the end of AIDS project, particularly in contexts where clinical interventions might transform clinical outcomes, but where the social, economic, and cultural determinants of HIV and AIDS remain largely intact and increasingly obscured.

Limits of Generalization between Categories and Implications for Theories of Category Specificity

PubMed Central

Bukach, Cindy M.; Phillips, W. Stewart; Gauthier, Isabel

2010-01-01

Both domain-specific and expertise accounts of category specialization assume that generalization occurs within a domain but not between domains. Yet it is often difficult to define the boundaries and critical features of object domains. Differences in how categories are defined make it difficult to adjudicate between accounts of category specificity and may lead to contradictory results. For example, evidence for whether car experts recruit the fusiform face area is mixed and this inconsistency may be due to the inclusion of antique cars in one of the studies. The current study tested the generalization of expertise from modern to antique cars and found that modern car experts showed expert discrimination and holistic processing of modern cars, but not antique cars. These findings suggest that the neural specialization underlying perceptual expertise is highly specific and may not generalize to distinct subclasses, even when they share some degree of perceptual and conceptual features.

Silencing women’s sexuality: global AIDS policies and the case of the female condom

Peters, Anny JTP; van Driel, Francien TM; Jansen, Willy HM

2013-01-01

Introduction The female condom is the only evidence-based AIDS prevention technology that has been designed for the female body; yet, most women do not have access to it. This is remarkable since women constitute the majority of all HIV-positive people living in sub-Saharan Africa, and gender inequality is seen as a driving force of the AIDS epidemic. In this study, we analyze how major actors in the AIDS prevention field frame the AIDS problem, in particular the female condom in comparison to other prevention technologies, in their discourse and policy formulations. Our aim is to gain insight into the discursive power mechanisms that underlie the thinking about AIDS prevention and women’s sexual agency. Methods We analyze the AIDS policies of 16 agencies that constitute the most influential actors in the global response to AIDS. Our study unravels the discursive power of these global AIDS policy actors, when promoting and making choices between AIDS prevention technologies. We conducted both a quantitative and qualitative analysis of how the global AIDS epidemic is being addressed by them, in framing the AIDS problem, labelling of different categories of people for targeting AIDS prevention programmes and in gender marking of AIDS prevention technologies. Results We found that global AIDS policy actors frame the AIDS problem predominantly in the context of gender and reproductive health, rather than that of sexuality and sexual rights. Men’s sexual agency is treated differently from women’s sexual agency. An example of such differentiation and of gender marking is shown by contrasting the framing and labelling of male circumcision as an intervention aimed at the prevention of HIV with that of the female condom. Conclusions The gender-stereotyped global AIDS policy discourse negates women’s agency in sexuality and their sexual rights. This could be an important factor in limiting the scale-up of female condom programmes and hampering universal access to

Given a fusion category C and an indecomposable C -module category M , the fusion category C^*_{_{M}} of C-module endofunctors of M is called the (Morita) dual fusion category of C with respect to M . We describe tensor functors between two arbitrary duals C^*_{_{M}} and D^*_N in terms of data associated to C and D . We apply the results to G-equivariantizations of fusion categories and group-theoretical fusion categories. We describe the orbits of the action of the Brauer-Picard group on the set of module categories and we propose a categorification of the Rosenberg-Zelinsky sequence for fusion categories.

Prior knowledge of category size impacts visual search.

PubMed

Wu, Rachel; McGee, Brianna; Echiverri, Chelsea; Zinszer, Benjamin D

2018-03-30

Prior research has shown that category search can be similar to one-item search (as measured by the N2pc ERP marker of attentional selection) for highly familiar, smaller categories (e.g., letters and numbers) because the finite set of items in a category can be grouped into one unit to guide search. Other studies have shown that larger, more broadly defined categories (e.g., healthy food) also can elicit N2pc components during category search, but the amplitude of these components is typically attenuated. Two experiments investigated whether the perceived size of a familiar category impacts category and exemplar search. We presented participants with 16 familiar company logos: 8 from a smaller category (social media companies) and 8 from a larger category (entertainment/recreation manufacturing companies). The ERP results from Experiment 1 revealed that, in a two-item search array, search was more efficient for the smaller category of logos compared to the larger category. In a four-item search array (Experiment 2), where two of the four items were placeholders, search was largely similar between the category types, but there was more attentional capture by nontarget members from the same category as the target for smaller rather than larger categories. These results support a growing literature on how prior knowledge of categories affects attentional selection and capture during visual search. We discuss the implications of these findings in relation to assessing cognitive abilities across the lifespan, given that prior knowledge typically increases with age. © 2018 Society for Psychophysiological Research.

Women and AIDS.

PubMed

Seghal, P N

1991-04-01

In this article, Dr. P.N. Sehgal, former director of the National Institute of Communicable Diseases in Delhi, explains the steps that women need to take to protect themselves against AIDS and discusses some issues facing women who have already contracted the disease. Because of women's lack of status in the family and society, it is harder for them to ensure their safety. Women based at home often lack information on AIDS, and those women who are informed sometimes depend on their male partner for financial support, which means that they are forced to engage in unsafe sexual practices. Safer sexual practices can reduce the risk for women. Though varying in degree of safety, some safer practices include: monogamous relationships between uninfected partners; the use of condoms for all types of sexual intercourse; non-penetrative sex practices (hugging, kissing, masturbating); reducing the number of sexual partners; avoiding sex when either of the partners has open sores or any STD. Pregnant women should also receive information concerning AIDS, including: a baby born from an HIV-infected mother has a 20-40% of being infected; the risk of transmission is higher when the mother already shows signs of AIDS; and an infected baby may die within the first few years of life. the HIV transmission may occur prepartum or during birth itself, but the risk of transmission from breastfeeding is extremely low. Dr. Sehgal stresses the need for privacy and confidentiality when dealing with carriers of the disease or when carrying out HIV testing. Above all, the rights of HIV-infected people must be protected.

Purpose To develop a new computer-aided diagnosis (CAD) scheme that computes visually sensitive image features routinely used by radiologists to develop a machine learning classifier and distinguish between the malignant and benign breast masses detected from digital mammograms. Methods An image dataset including 301 breast masses was retrospectively selected. From each segmented mass region, we computed image features that mimic five categories of visually sensitive features routinely used by radiologists in reading mammograms. We then selected five optimal features in the five feature categories and applied logistic regression models for classification. A new CAD interface was also designed to show lesion segmentation, computed feature values and classification score. Results Areas under ROC curves (AUC) were 0.786±0.026 and 0.758±0.027 when to classify mass regions depicting on two view images, respectively. By fusing classification scores computed from two regions, AUC increased to 0.806±0.025. Conclusion This study demonstrated a new approach to develop CAD scheme based on 5 visually sensitive image features. Combining with a “visual aid” interface, CAD results may be much more easily explainable to the observers and increase their confidence to consider CAD generated classification results than using other conventional CAD approaches, which involve many complicated and visually insensitive texture features.

"I'll have one of each": how separating rewards into (meaningless) categories increases motivation.

PubMed

Wiltermuth, Scott S; Gino, Francesca

2013-01-01

We propose that separating rewards into categories can increase motivation, even when those categories are meaningless. Across six experiments, people were more motivated to obtain one reward from one category and another reward from another category than they were to obtain two rewards from a pool that included all items from either reward category. As a result, they worked longer when potential rewards for their work were separated into meaningless categories. This categorization effect persisted regardless of whether the rewards were presented using a gain or loss frame. Using both moderation and mediation analyses, we found that categorizing rewards had these positive effects on motivation by increasing the degree to which people felt they would "miss out" if they did not obtain the second reward. We discuss implications for research on motivation and incentives.

Cognitive representations of AIDS: a phenomenological study.

PubMed

Anderson, Elizabeth H; Spencer, Margaret Hull

2002-12-01

Cognitive representations of illness determine behavior. How persons living with AIDS image their disease might be key to understanding medication adherence and other health behaviors. The authors' purpose was to describe AIDS patients' cognitive representations of their illness. A purposive sample of 58 men and women with AIDS were interviewed. Using Colaizzi's (1978) phenomenological method, rigor was established through application of verification, validation, and validity. From 175 significant statements, 11 themes emerged. Cognitive representations included imaging AIDS as death, bodily destruction, and just a disease. Coping focused on wiping AIDS out of the mind, hoping for the right drug, and caring for oneself. Inquiring about a patient's image of AIDS might help nurses assess coping processes and enhance nurse-patient relationships.

Women and AIDS: introduction.

PubMed

Krieger, N; Margo, G

1991-01-01

Around the world, more and more women--principally poor women of color--are being diagnosed with and are dying of AIDS, the acquired immune deficiency syndrome. Yet, effective and appropriate prevention programs for women are sorely missing from the global program to control AIDS. To help us understand why this gap exists, and what we must do to close it, the three articles in this issue focus on women and AIDS. Examining the situation in such countries as Zimbabwe and South Africa, as well as in other economically underdeveloped and developed regions, the authors argue that women with the least control over their bodies and their lives are at greatest risk of acquiring AIDS. For example, the high rate of infection among women in Africa cannot be understood apart from the legacy of colonialism (including land expropriation and the forced introduction of a migrant labor system) and the insidious combination of traditional and European patriarchal values. Only by recognizing the socioeconomic and cultural determinants of both disease and sexual behavior, and only by incorporating these insights into our AIDS prevention programs, will we be able to curb the spread of this lethal disease.

The National AIDS Hotline (NAH), a service of the Centers for Disease Control (CDC), is an information resource for the population of the United States, its Territories, and Puerto Rico concerning the human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS). Since its inception in 1983, NAH has grown to be the world's largest health-related hotline service. NAH has received an average of more than 1.4 million calls per year since October 1987. Services of NAH include responding to the public's questions about HIV and AIDS and providing referrals to State and local resources. All services, including HIV and AIDS publications, are provided free of charge. The public contacts NAH 24 hours a day, 7 days a week, through a toll-free telephone system. Services are available to English-speaking, Spanish-speaking, and deaf populations. Each service has its own telephone number--English-speaking, 1-800-342-2437; Spanish-speaking, 1-800-344-7432; TTY service for the deaf, 1-800-243-7889. NAH employs approximately 170 information specialists to answer calls. The facility uses modern telecommunications technology to effectively manage and direct calls to 43 work stations. Each work station is supported by a personal computer that allows access to CDC's National AIDS Clearinghouse data bases for referrals and publication ordering. NAH ensures that information provided to the public is current, accurate, and consistent with approved government policy. Quality assurance reviews address call management, delivery of information, and content of calls. PMID:1659708

2012-01-01

The objective of this study is to conduct a quantitative risk assessment of multiple factors influencing HIV/AIDS transmission through unprotected sexual practices among HIV-seropositive men. A knowledgebase was developed by reviewing different published sources. The data were collected from different sources including Centers for Disease Control and Prevention, selected journals, and reports. The risk pathway scenario tree was developed based on a comprehensive review of published literature. The variables are organized into nine major parameter categories. Monte Carlo simulations for the quantitative risk assessment of HIV/AIDS transmission was executed with the software @Risk 4.0 (Palisade Corporation). Results show that the value for the likelihood of unprotected sex due to having less knowledge about HIV/AIDS and negative attitude toward condom use and safer sex ranged from 1.24 × 10(-5) to 8.47 × 10(-4) with the mean and standard deviation of 1.83 × 10(-4) and 8.63 × 10(-5), respectively. The likelihood of unprotected sex due to having greater anger-hostility, anxiety, less satisfied with aspects of life, and greater depressive symptoms ranged from 2.76 × 10(-9) to 5.34 × 10(-7) with the mean and standard deviation of 5.23 × 10(-8) and 3.58 × 10(-8), respectively. The findings suggest that HIV/AIDS research and intervention programs must be focused on behavior, and the broader setting within which individual risky behaviors occur.

Reconceptualizing 'extremism' and 'moderation': from categories of analysis to categories of practice in the construction of collective identity.

PubMed

Hopkins, Nick; Kahani-Hopkins, Vered

2009-03-01

Much psychological research employs the categories of extremism and moderation as categories of analysis (e.g. to identify the psychological bases for, and consequences of, holding certain positions). This paper argues these categorizations inevitably reflect one's values and taken-for-granted assumptions about social reality and that their use as analytic categories limits our ability to explore what is really important: social actors' own constructions of social reality. In turn we argue that if we are to focus on this latter, there may be merit in exploring how social actors themselves use the categories of moderation and extremism to construct their own terms of reference. That is we propose to re-conceptualize the categories of moderation and extremism as categories of practice rather than analysis. The utility of this approach is illustrated with qualitative data. We argue that these data illustrate the importance of respecting social actors' own constructions of social reality (rather than imposing our own). Moreover, we argue that categories of moderation and extremism may be employed by social actors in diverse ways to construct different terms of reference and so recruit support for different identity-related projects.

Nutrition care of AIDS patients.

PubMed

Resler, S S

1988-07-01

Often the complications of the acquired immunodeficiency syndrome (AIDS) have a negative impact on nutritional status. Weight loss and protein depletion are commonly seen among the AIDS population. Though the relationship between disease progression and nutritional status has not been established, maintaining good nutritional status may support response to treatment of opportunistic infections and improve patient strength and comfort. Increased nutrient needs, decreased nutrient intake, and impaired nutrient absorption contribute to malnutrition in AIDS patients. Causes of decreased nutrient intake and absorption may be poor appetite, oral and esophageal pain, mechanical problems with eating, and gastrointestinal complications (diarrhea and malabsorption). Causes of these impediments to maintaining nutritional status are discussed, and suggestions to overcome them are given. Dietitians working with AIDS patients need to understand how the complications of the disease might affect nutritional status so that strategies for nutrition treatment can be developed. Nutrition care of AIDS patients requires that dietitians and their support personnel provide supportive, nonjudgmental care. The patients should be included in decision making regarding their nutrition care. Caring for AIDS patients in the community and through home care agencies represents an area in need of the expertise of a dietetics professional.

The impacts of AIDS movements on the policy responses to HIV/AIDS in Brazil and South Africa: A comparative analysis

2013-01-01

Brazil and South Africa were among the first countries profoundly impacted by the HIV/AIDS epidemic and had similar rates of HIV infection in the early 1990s. Today, Brazil has less than 1% adult HIV prevalence, implemented treatment and prevention programmes early in the epidemic, and now has exemplary HIV/AIDS programmes. South Africa, by contrast, has HIV prevalence of 18% and was, until recently, infamous for its delayed and inappropriate response to the HIV/ AIDS epidemic. This article explores how differing relationships between AIDS movements and governments have impacted the evolving policy responses to the AIDS epidemic in both countries, including through AIDS programme finance, leadership and industrial policy related to production of generic medicines.

In the Name of Brevity: The Problem with Binary HIV Risk Categories

According to the ‘Consolidated Guidelines on HIV Prevention, Diagnosis, Treatment and Care for Key Populations’ there are five groups of people at elevated risk of HIV, including ‘transgender women or transgender men who have receptive anal sex with men.’ Although cost effectiveness strategies and best practice lessons recommend targeting specific populations for HIV prevention, existing risk categories lack specificity, and may in fact cause further confusion. Existing categories of risk often perpetuate notions of gender and sexuality that can erroneously exclude, alienate, and stigmatize those who are at the highest risk and thus should be prioritized. We review the troubled history of the MSM category and the problematic conflation of trans feminine individuals and MSM in much of the existing HIV literature, and how this practice has stymied progress in slowing the HIV epidemic in the most at-risk groups, including those who do not fit neatly into binary notions of gender and sex. We draw from examples in the field, specifically among trans feminine people in Beirut and San Francisco, to illustrate the lived experiences of individuals whose identities may not fit into Euro-Atlantic constructs of HIV prevention categories.

Long-term care survey reveals challenges. Facilities grapple with five broad issues, including changes in leadership and AIDS.

PubMed

Westhoff, L J; Schaefer, J C

1993-05-01

The Catholic Health Association's 1992 survey of Catholic long-term care (LTC) facilities identified five broad issues LTC facilities face in the 1990s: leadership, system affiliation, community programs, resident issues, and care of persons with AIDS. The transition to lay leadership presents new challenges to the relationship between LTC facilities and their sponsors. Despite the dominance of religious sponsors, an increasing number of laypersons are serving as healthcare administrators both in long-term and acute care. Thirty percent of respondents reported being affiliated with a multi-institutional system. This percentage has changed little in the past few years, although the number of facilities that are system members continues to increase at the fastest rate of any type of LTC facility. Only 27 percent of survey respondents said they provide educational or informational programs for persons in their communities. Thirty-nine percent of system-affiliated LTC facilities reported offering such programs. One encouraging finding shows that 80 percent of facilities have written policies for living wills, 64 percent for designated proxy, and 86 percent for durable power of attorney for healthcare. LTC providers are struggling to determine their role in caring for persons with HIV and AIDS. Only 3.6 percent of respondents care for residents with AIDS. A major problem LTC administrators face is a fear of potential infection of staff or residents.

We assessed HIV/AIDS expenditures in Dehong Prefecture, Yunnan Province, one of the highest prevalence regions in China, and describe funding sources and spending for different categories of HIV-related interventions and at-risk populations. 2010 HIV/AIDS expenditures in Dehong Prefecture were evaluated based on UNAIDS' National AIDS Spending Assessment methodology. Nearly 93% of total expenditures for HIV/AIDS was contributed by public sources. Of total expenditures, 52.7% was allocated to treatment and care, 24.5% to program management and administration and 19.8% to prevention. Spending on treatment and care was primarily allocated to the treatment of opportunistic infections. Most (40.4%) prevention spending was concentrated on most-at-risk populations, injection drug users (IDUs), sex workers, and men who have sex with men (MSM), with 5.5% allocated to voluntary counseling and testing. Prevention funding allocated for MSM, partners of people living with HIV and prisoners and other confined populations was low compared to the disproportionate burden of HIV/AIDS in these populations. Overall, people living with HIV accounted for 57.57% of total expenditures, while most-at-risk populations accounted for only 7.99%. Our study demonstrated the applicability of NASA for tracking and assessing HIV expenditure in the context of China, it proved to be a useful tool in understanding national HIV/AIDS response from financial aspect, and to assess the extent to which HIV expenditure matches epidemic patterns. Limited funding for primary prevention and prevention for MSM, prisoners and partners of people living with HIV, signal that resource allocation to these key areas must be strengthened. Comprehensive analyses of regional and national funding strategies are needed to inform more equitable, effective and cost-effective HIV/AIDS resource allocation.

Issues concerning women and AIDS: sexuality.

PubMed

Whipple, B

1992-01-01

In the US and globally women are contracting the human immunodeficiency virus (HIV) and developing the acquired immunodeficiency syndrome (AIDS) the fastest. Worldwide, HIV is transmitted primarily through heterosexual intercourse. In the US, the proportion of women who have contracted AIDS by heterosexual transmission has increased from 11% in 1984 to 34% in 1990. Women are at a greater risk than men for transmission by heterosexual intercourse as the ratio of women to men who acquire AIDS by heterosexual transmission is 3 to 1. Furthermore, 25% of AIDS cases caused by heterosexual transmission or iv drug use occurs in women. Although women often develop HIV-related serious gynecologic problems, including cervical cancer and refractory vaginal candidiasis, these conditions do not fall within the Centers for Disease Control definition of AIDS. Women who have gynecologic symptoms are not diagnosed as having AIDS, are not eligible for AIDS benefits, and live half as long as men do once they are diagnosed as being HIV infected. Little is known about the characteristics of HIV infection or AIDS in women. Sexually transmitted diseases (STDs) seem to act as cofactors for HIV infection. The human papilloma virus or genital warts, the herpes simplex virus, syphilis, chancroid, recurrent vaginal candidiasis, abnormal Pap smears, cervical neoplasias, and pelvic inflammatory disease have been associated with HIV infection in women. HIV infection should be considered in all women with symptoms of any of these disorders. Nurses must first become aware of the clinical manifestations of HIV infection specific to women. Nursing interventions should educate about safer-sex including condom use with nonoxynol 9, and the risks of sharing needles. Strategies must be developed that provide empowerment skills and are sensitive to the women's cultural, religious, and ethnic background, beliefs, and values.

Dual-learning systems during speech category learning

PubMed Central

Chandrasekaran, Bharath; Yi, Han-Gyol; Maddox, W. Todd

2013-01-01

Dual-systems models of visual category learning posit the existence of an explicit, hypothesis-testing ‘reflective’ system, as well as an implicit, procedural-based ‘reflexive’ system. The reflective and reflexive learning systems are competitive and neurally dissociable. Relatively little is known about the role of these domain-general learning systems in speech category learning. Given the multidimensional, redundant, and variable nature of acoustic cues in speech categories, our working hypothesis is that speech categories are learned reflexively. To this end, we examined the relative contribution of these learning systems to speech learning in adults. Native English speakers learned to categorize Mandarin tone categories over 480 trials. The training protocol involved trial-by-trial feedback and multiple talkers. Experiment 1 and 2 examined the effect of manipulating the timing (immediate vs. delayed) and information content (full vs. minimal) of feedback. Dual-systems models of visual category learning predict that delayed feedback and providing rich, informational feedback enhance reflective learning, while immediate and minimally informative feedback enhance reflexive learning. Across the two experiments, our results show feedback manipulations that targeted reflexive learning enhanced category learning success. In Experiment 3, we examined the role of trial-to-trial talker information (mixed vs. blocked presentation) on speech category learning success. We hypothesized that the mixed condition would enhance reflexive learning by not allowing an association between talker-related acoustic cues and speech categories. Our results show that the mixed talker condition led to relatively greater accuracies. Our experiments demonstrate that speech categories are optimally learned by training methods that target the reflexive learning system. PMID:24002965

From marginal to marginalised: The inclusion of men who have sex with men in global and national AIDS programmes and policy.

PubMed

McKay, Tara

2016-01-01

In the last decade, gay men and other men who have sex with men (msm) have come to the fore of global policy debates about AIDS prevention. In stark contrast to programmes and policy during the first two decades of the epidemic, which largely excluded msm outside of the Western countries, the Joint United Nations Programme on HIV/AIDS now identifies gay men and other msm as 'marginalized but not marginal' to the global response. Drawing on archival data and five waves of United Nations Country Progress Reports on HIV/AIDS (2001-2012), this paper examines the productive power of international organisations in the development and diffusion of the msm category, and considers how international organisations have shaped the interpretation of msm in national policies and programmes. These data show that the increasing separation of sexual identity and sexual behaviour at the global level helped to construct notions of risk and disease that were sufficiently broad to accommodate the diverse interests of global policy-makers, activists, and governments. However, as various international and national actors have attempted to develop prevention programmes for msm, the failure of the msm category to map onto lived experience is increasingly apparent.

HIV / AIDS and the law.

1997-09-01

Since HIV is sexually transmitted, people living with AIDS and HIV (PWA/PHA) risk being stigmatized as immoral and promiscuous and they are often discriminated against in society. To this effect, the South African AIDS Law Project and Lawyers for Human Rights have developed a comprehensive resource manual detailing human rights with a special emphasis on issues relevant to PWA/PHA. The concept of the manual aimed to look at the legal and human rights questions that have been raised by the HIV/AIDS epidemic; inform people living with HIV/AIDS about their rights and the law; provide people working in businesses, trade unions, and nongovernmental organization with information about correct and incorrect responses to HIV/AIDS; and give victims of discrimination ideas on how to fight back. This manual initially introduces basic facts about HIV and AIDS and then describes the legal system and the Bill of Rights within the new South African Constitution. The main areas of focus in the manual include: 1) patient's medical rights, 2) employment rights, 3) women's rights, 4) the rights of lesbians and gay men, 5) the rights of youth and children, 6) the rights of prisoners, 7) social support for PWA, 8) HIV/AIDS and insurance law, 9) power of attorney and making wills, 10) criminal law, and 11) legal remedies, such as using the law to protect one's rights.

Hippocampal activation during episodic and semantic memory retrieval: comparing category production and category cued recall.

PubMed

Ryan, Lee; Cox, Christine; Hayes, Scott M; Nadel, Lynn

2008-01-01

Whether or not the hippocampus participates in semantic memory retrieval has been the focus of much debate in the literature. However, few neuroimaging studies have directly compared hippocampal activation during semantic and episodic retrieval tasks that are well matched in all respects other than the source of the retrieved information. In Experiment 1, we compared hippocampal fMRI activation during a classic semantic memory task, category production, and an episodic version of the same task, category cued recall. Left hippocampal activation was observed in both episodic and semantic conditions, although other regions of the brain clearly distinguished the two tasks. Interestingly, participants reported using retrieval strategies during the semantic retrieval task that relied on autobiographical and spatial information; for example, visualizing themselves in their kitchen while producing items for the category kitchen utensils. In Experiment 2, we considered whether the use of these spatial and autobiographical retrieval strategies could have accounted for the hippocampal activation observed in Experiment 1. Categories were presented that elicited one of three retrieval strategy types, autobiographical and spatial, autobiographical and nonspatial, and neither autobiographical nor spatial. Once again, similar hippocampal activation was observed for all three category types, regardless of the inclusion of spatial or autobiographical content. We conclude that the distinction between semantic and episodic memory is more complex than classic memory models suggest.

In Experiment 1, we compared hippocampal fMRI activation during a classic semantic memory task, category production, and an episodic version of the same task, category cued recall. Left hippocampal activation was observed in both episodic and semantic conditions, although other regions of the brain clearly distinguished the two tasks. Interestingly, participants reported using retrieval strategies during the semantic retrieval task that relied on autobiographical and spatial information; for example, visualizing themselves in their kitchen while producing items for the category kitchen utensils. In Experiment 2, we considered whether the use of these spatial and autobiographical retrieval strategies could have accounted for the hippocampal activation observed in Experiment 1. Categories were presented that elicited one of three retrieval strategy types, autobiographical and spatial, autobiographical and nonspatial, and neither autobiographical nor spatial. Once again, similar hippocampal activation was observed for all three category types, regardless of the inclusion of spatial or autobiographical content. We conclude that the distinction between semantic and episodic memory is more complex than classic memory models suggest. PMID:18420234

This study investigates category goodness judgments of /r/ in adults and children with and without residual speech errors (RSEs) using natural speech stimuli. Thirty adults, 38 children with RSE (ages 7-16) and 35 age-matched typically developing (TD) children provided category goodness judgments on whole words, recorded from 27 child speakers, with /r/ in various phonetic environments. The salient acoustic property of /r/ - the lowered third formant (F3) - was normalized in two ways. A logistic mixed-effect model quantified the relationships between listeners' responses and the third formant frequency, vowel context and clinical group status. Goodness judgments from the adult group showed a statistically significant interaction with the F3 parameter when compared to both child groups (p < 0.001) using both normalization methods. The RSE group did not differ significantly from the TD group in judgments of /r/. All listeners were significantly more likely to judge /r/ as correct in a front-vowel context. Our results suggest that normalized /r/ F3 is a statistically significant predictor of category goodness judgments for both adults and children, but children do not appear to make adult-like judgments. Category goodness judgments do not have a clear relationship with /r/ production abilities in children with RSE. These findings may have implications for clinical activities that include category goodness judgments in natural speech, especially for recorded productions.

Development of a Spanish HIV/AIDS Symptom Management Guidebook.

PubMed

Román, Elizabeth; Chou, Fang-Yu

2011-07-01

To provide culturally appropriate HIV/AIDS patient care, it is important to develop symptom management patient education materials for patients with different cultural backgrounds. The purpose of this study was to develop a Spanish version of the Symptom Management Guidebook: Strategies for People Living with HIV/AIDS guidelines and verify its content, perceived feasibility, and usefulness with HIV/AIDS care providers and people living with HIV/AIDS in Puerto Rico. The Symptom Management Guidebook includes self-care strategies to manage 14 common HIV-related symptoms. The Spanish version was developed by adopting and translating through forward and backward translation methods. Seven HIV/AID Shealth care providers from San Juan, Puerto Rico, were invited to review and revise the contents. Ten people living with HIV/AIDS from a community AIDS clinic in San Juan participated in a focus group to review the guidebook and discussed its usefulness and feasibility for managing their symptoms. Participants expressed positive responses and considered an educational guidebook as a helpful tool for self-managing their symptoms. Results suggested that this guidebook may be useful as an intervention strategy for symptom management in HIV/AIDS patients. Future research can include testing self-managing intervention and its outcomes in culturally diverse HIV/AIDS patients.

The long-term effectiveness of human immunodeficiency virus (HIV) treatments containing integrase inhibitors is unknown. We use observational data from the Centers for AIDS Research Network of Integrated Clinical Systems and the Centers for Disease Control and Prevention to estimate 4-year risk of AIDS and all-cause mortality among 415 patients starting a raltegravir regimen compared to 2646 starting an efavirenz regimen (both regimens include emtricitabine and tenofovir disoproxil fumarate). We account for confounding and selection bias as well as generalizability by standardization for measured variables, and present both observational intent-to-treat and per-protocol estimates. At treatment initiation, 12% of patients were female, 36% black, 13% Hispanic; median age was 37 years, CD4 count 321 cells/µL, and viral load 4.5 log10 copies/mL. Two hundred thirty-five patients incurred an AIDS-defining illness or died, and 741 patients left follow-up. After accounting for measured differences, the 4-year risk was similar among those starting both regimens (ie, intent-to treat hazard ratio [HR], 0.96 [95% confidence interval {CI}, .63-1.45]; risk difference, -0.9 [95% CI, -4.5 to 2.7]), as well as among those remaining on regimens (ie, per-protocol HR, 0.95 [95% CI, .59-1.54]; risk difference, -0.5 [95% CI, -3.8 to 2.9]). Raltegravir and efavirenz-based initial antiretroviral therapy have similar 4-year clinical effects. Vigilance regarding longer-term comparative effectiveness of HIV regimens using observational data is needed because large-scale experimental data are not forthcoming. © The Author 2017.

Understanding the low uptake of bone-anchored hearing aids: a review.

PubMed

Powell, R; Wearden, A; Pardesi, S M; Green, K

2017-03-01

Bone-anchored hearing aids improve hearing for patients for whom conventional behind-the-ear aids are problematic. However, uptake of bone-anchored hearing aids is low and it is important to understand why this is the case. A narrative review was conducted. Studies examining why people accept or decline bone-anchored hearing aids and satisfaction levels of people with bone-anchored hearing aids were reviewed. Reasons for declining bone-anchored hearing aids included limited perceived benefits, concerns about surgery, aesthetic concerns and treatment cost. No studies providing in-depth analysis of the reasons for declining or accepting bone-anchored hearing aids were identified. Studies of patient satisfaction showed that most participants reported benefits with bone-anchored hearing aids. However, most studies used cross-sectional and/or retrospective designs and only included people with bone-anchored hearing aids. Important avenues for further research are in-depth qualitative research designed to fully understand the decision-making process for bone-anchored hearing aids and rigorous quantitative research comparing satisfaction of people who receive bone-anchored hearing aids with those who receive alternative (or no) treatments.

[Guidelines for the facilitation of wholeness in patients with AIDS: the experience of patients with AIDS: I].

Torrente, A C; Greeff, M

1996-03-01

AIDS will be remembered as the illness that was discovered in the 1980s of which the effects of this epidemic were only realised in the 1990s. Statistics show that the number of patients with AIDS increase annually because of the number of patients now diagnosed as HIV infected. Statistics indicate that AIDS has a much wider impact on the community than only homosexuals and drug-dependent people. Much attention is paid currently to the prevention of AIDS, but the problem is vested in the third phase of the HIV infection, namely AIDS. Nurses will be more and more exposed to the patient with AIDS and she can make a valuable contribution to facilitating the quest to wholeness of the patient with AIDS. This research was aimed at exploring and describing the experiences of the patient with AIDS and to lay down guidelines for the nurse and the psychiatric nurse specialist as consultant to facilitate the quest for wholeness of the patient with AIDS. A exploratory, descriptive contextual study was done with the aim of achieving insight into the experiences of the patient with AIDS, by way of a specific convenience test sample, five patients who complied with the set criteria were included in the research. The application possibilities of this research are generally set out as regards practice, research and teaching, and also as specific guidelines for the nurse treating the patient with AIDS. By following the guidelines set out in this research, the nurse can facilitate the patient's quest for wholeness.

2016-01-01

We conducted a case study of the Zimbabwe National AIDS Trust Fund ('AIDS Levy') as an approach to domestic government financing of the response to HIV and AIDS. Data came from three sources: a literature review, including a search for grey literature, review of government documents from the Zimbabwe National AIDS Council (NAC), and key informant interviews with representatives of the Zimbabwean government, civil society and international organizations. The literature search yielded 139 sources, and 20 key informants were interviewed. Established by legislation in 1999, the AIDS Levy entails a 3% income tax for individuals and 3% tax on profits of employers and trusts (which excluded the mining industry until 2015). It is managed by the parastatal NAC through a decentralized structure of AIDS Action Committees. Revenues increased from inception to 2006 through 2008, a period of economic instability and hyperinflation. Following dollarization in 2009, annual revenues continued to increase, reaching US$38.6 million in 2014. By policy, at least 50% of funds are used for purchase of antiretroviral medications. Other spending includes administration and capital costs, HIV prevention, and monitoring and evaluation. Several financial controls and auditing systems are in place. Key informants perceived the AIDS Levy as a 'homegrown' solution that provided country ownership and reduced dependence on donor funding, but called for further increased transparency, accountability, and reduced administrative costs, as well as recommended changes to increase revenue. The Zimbabwe AIDS Levy has generated substantial resources, recently over US$35 million per year, and signals an important commitment by Zimbabweans, which may have helped attract other donor resources. Many key informants considered the Zimbabwe AIDS Levy to be a best practice for other countries to follow.

As the global HIV/AIDS pandemic nears the end of its third decade, the challenges of efficient mobilisation of funds and management of resources are increasingly prominent. The aids2031 project modelled long-term funding needs for HIV/AIDS in developing countries with a range of scenarios and substantial variation in costs: ranging from US$397 to $722 billion globally between 2009 and 2031, depending on policy choices adopted by governments and donors. We examine what these figures mean for individual developing countries, and estimate the proportion of HIV/AIDS funding that they and donors will provide. Scenarios for expanded HIV/AIDS prevention, treatment, and mitigation were analysed for 15 representative countries. We suggest that countries will move in increasingly divergent directions over the next 20 years; middle-income countries with a low burden of HIV/AIDS will gradually be able to take on the modest costs of their HIV/AIDS response, whereas low-income countries with a high burden of disease will remain reliant upon external support for their rapidly expanding costs. A small but important group of middle-income countries with a high prevalence of HIV/AIDS (eg, South Africa) form a third category, in which rapid scale-up in the short term, matched by outside funds, could be phased down within 10 years assuming strategic investments are made for prevention and efficiency gains are made in treatment.

Category-based predictions: influence of uncertainty and feature associations.

PubMed

Ross, B H; Murphy, G L

1996-05-01

Four experiments examined how people make inductive inferences using categories. Subjects read stories in which 2 categories were mentioned as possible identities of an object. The less likely category was varied to determine if people were using it, as well as the most likely category, in making predictions about the object. Experiment 1 showed that even when categorization uncertainty was emphasized, subjects used only 1 category as the basis for their prediction. Experiments 2-4 examined whether people would use multiple categories for making predictions when the feature to be predicted was associated to the less likely category. Multiple categories were used in this case, but only in limited circumstances; furthermore, using multiple categories in 1 prediction did not cause subjects to use them for subsequent predictions. The results increase the understanding of how categories are used in inductive inference.

Nigerians divided on AIDS prevalence. International / case rates.

PubMed

1994-10-10

The World Health Organization (WHO) estimates that more than half a million people in Africa had AIDS in 1993 alone. According to the WHO, another 10 million Africans now carry HIV, including more than half a million in Nigeria. But some Nigerian scientists charge that their counterparts in the industrialized world deliberately inflate the figures to create the impression that Africa is as poor in health as it is economically. On the other hand, some feel AIDS has been killing more people in Nigeria than official reports show. Professor Akande Abdulkarim, a biochemist of the University of Khartoum, Sudan, argued that AIDS is not as pandemic as the Western scientists maintain. Abdulkarim wondered how AIDS, first discovered among homosexual communities in the United States, had suddenly become an African scourge. He added that body slimness as one of the manifestations of AIDS could be deceitful since Africa has about 11 diseases which cause weight loss, including tuberculosis. Since the discovery of AIDS, Nigerian health officials have alerted the nation, quoting very high figures even though not many people go for AIDS screening in the country. The Health and Social Services Minister announced early in 1994 that AIDS prevalence had risen from 300 reported cases in 1992 to 962 in 1993. More than 600,000 Nigerians had tested HIV-positive since 1986, when the disease was first diagnosed in the country. As of December 1993, only 100 Nigerians were officially deemed to have died from AIDS. But another scientist cautioned Nigerians against being deluded by the low AIDS-mortality figure reported; the low death rate was misleading because some deaths have been wrongly attributed to some other ailments.

Malignancies in HIV-Infected and AIDS Patients.

Currently, HIV infection and AIDS are still one of the most important epidemic diseases around the world. As early in the initial stage of HIV epidemic, the high incidence of ADCs including Kaposi sarcoma and non-Hodgkin's lymphoma was the substantial amount of disease burden of HIV infection and AIDS. With the increasing accessibility of HAART and improving medical care for HIV infection and AIDS, AIDS-related illness including ADCs has dramatically decreased. Meanwhile, the incidence of NADCs rises in PLWH. Compared with the general population, most of cancers are more likely to attack PLWH, and NADCs in PLWH were characterized as earlier onset and more aggressive. However, the understanding for cancer development in PLWH is still dimness. Herein, we reviewed the current knowledge of epidemiology and pathogenesis for malignancies in PLWH summarized from recent studies. On the basis of that, we discussed the special considerations for cancer treatment in PLWH. As those malignancies could be the major issue for HIV infection or AIDS in the future, we expect enhanced investigations, surveillances, and clinical trial for improving the understanding and management for cancers developed in PLWH.

Jonsson, C; Soderholm, P

1995-01-01

This paper is concerned with the emergence of transnational cooperative structures in response to AIDS. Of chief concern are efforts to create and maintain links among and between intergovernmental organizations (IGO) in the UN system and the many heterogenous organizations usually included under the nongovernmental organization (NGO) label. After discussing the nature of the AIDS issue, the authors focus upon the various ways of framing the AIDS issue and the effort by the Global Program on AIDS to coordinate IGO and NGO activities. In closing, they identify lessons and insights of broader applicability emanating from the AIDS case. The paper discusses the nature of AIDS, AIDS as a medical problem, AIDS as a human rights problem, AIDS as a socioeconomic problem, forging IGO-NGO links, an international NGO forum, informal networking, NGOs and AIDS-related foreign assistance, representation, formal versus informal coordination, costs of network building, degree of organization, and expertise.

Identification of prelinguistic phonological categories.

Ramsdell, Heather L; Oller, D Kimbrough; Buder, Eugene H; Ethington, Corinna A; Chorna, Lesya

2012-12-01

The prelinguistic infant's babbling repertoire of syllables--the phonological categories that form the basis for early word learning--is noticed by caregivers who interact with infants around them. Prior research on babbling has not explored the caregiver's role in recognition of early vocal categories as foundations for word learning. In the present work, the authors begin to address this gap. The authors explored vocalizations produced by 8 infants at 3 ages (8, 10, and 12 months) in studies illustrating identification of phonological categories through caregiver report, laboratory procedures simulating the caregiver's natural mode of listening, and the more traditional laboratory approach (phonetic transcription). Caregivers reported small repertoires of syllables for their infants. Repertoires of similar size and phonetic content were discerned in the laboratory by judges who simulated the caregiver's natural mode of listening. However, phonetic transcription with repeated listening to infant recordings yielded repertoire sizes that vastly exceeded those reported by caregivers and naturalistic listeners. The results suggest that caregiver report and naturalistic listening by laboratory staff can provide a new way to explore key characteristics of early infant vocal categories, a way that may provide insight into later speech and language development.

Clinical Criteria for Physician Aid in Dying.

PubMed

Orentlicher, David; Pope, Thaddeus Mason; Rich, Ben A

2016-03-01

More than 20 years ago, even before voters in Oregon had enacted the first aid in dying (AID) statute in the United States, Timothy Quill and colleagues proposed clinical criteria AID. Their proposal was carefully considered and temperate, but there were little data on the practice of AID at the time. (With AID, a physician writes a prescription for life-ending medication for a terminally ill, mentally capacitated adult.) With the passage of time, a substantial body of data on AID has developed from the states of Oregon and Washington. For more than 17 years, physicians in Oregon have been authorized to provide a prescription for AID. Accordingly, we have updated the clinical criteria of Quill, et al., based on the many years of experience with AID. With more jurisdictions authorizing AID, it is critical that physicians can turn to reliable clinical criteria. As with any medical practice, AID must be provided in a safe and effective manner. Physicians need to know (1) how to respond to a patient's inquiry about AID, (2) how to assess patient decision making capacity, and (3) how to address a range of other issues that may arise. To ensure that physicians have the guidance they need, Compassion & Choices convened the Physician Aid-in-Dying Clinical Criteria Committee, in July 2012, to create clinical criteria for physicians who are willing to provide AID to patients who request it. The committee includes experts in medicine, law, bioethics, hospice, nursing, social work, and pharmacy. Using an iterative consensus process, the Committee drafted the criteria over a one-year period.

SUSTAIN: a network model of category learning.

PubMed

Love, Bradley C; Medin, Douglas L; Gureckis, Todd M

2004-04-01

SUSTAIN (Supervised and Unsupervised STratified Adaptive Incremental Network) is a model of how humans learn categories from examples. SUSTAIN initially assumes a simple category structure. If simple solutions prove inadequate and SUSTAIN is confronted with a surprising event (e.g., it is told that a bat is a mammal instead of a bird), SUSTAIN recruits an additional cluster to represent the surprising event. Newly recruited clusters are available to explain future events and can themselves evolve into prototypes-attractors-rules. SUSTAIN's discovery of category substructure is affected not only by the structure of the world but by the nature of the learning task and the learner's goals. SUSTAIN successfully extends category learning models to studies of inference learning, unsupervised learning, category construction, and contexts in which identification learning is faster than classification learning.

Factors Influencing Help Seeking, Hearing Aid Uptake, Hearing Aid Use and Satisfaction With Hearing Aids: A Review of the Literature

Objectives: This descriptive summary of the literature provides an overview of the available studies (published between January 1980 and January 2009) on correlates of help-seeking behavior for hearing loss, hearing-aid uptake, hearing-aid use, and satisfaction with the device. Methods: Publications were identified by structured searches in Pubmed and Cinahl and by inspecting the reference lists of relevant articles. The articles covered different stages that a person with hearing impairment may go through: prior to hearing aid fitting, the period covering the fitting and the period post hearing aid fitting. Inclusion of articles occurred according to strict inclusion and exclusion criteria. Data were extracted by two independent researchers. Thirty-nine papers were included that identified 31 factors examined in relation to the four outcome measures. These covered personal factors (e.g., source of motivation, expectation, attitude), demographic factors (e.g., age, gender) and external factors (e.g., cost, counseling). Only two studies covered the actual fitting process. There was only one factor positively affecting all four outcome variables. This was self-reported hearing disability. The vast majority of studies showed no relationship of age and gender with any of the outcome domains. Discussion and conclusion: Whereas research of the last 28 years yielded valuable information regarding relevant and irrelevant factors in hearing aid health care, there are still many relevant issues that have never been investigated in controlled studies. These are discussed. PMID:21109549

Mathematical models of the AIDS epidemic: An historical perspective

DOE Office of Scientific and Technical Information (OSTI.GOV)

Stanley, E.A.

1988-01-01

Researchers developing mathematical models of the spreading of HIV, the Human Immunodeficiency Virus that causes AIDS, hope to achieve a number of goals. These goals may be classified rather broadly into three categories: understanding, prediction, and control. Understanding which are the key biological and sociological processes spreading this epidemic and leading to the deaths of those infected will allow AIDS researchers to collect better data and to identify ways of slowing the epidemic. Predicting the groups at risk and future numbers of ill people will allow an appropriate allocation of health-care resources. Analysis and comparison of proposed control methods willmore » point out unexpected consequences and allow a better design of these programs. The processes which lead to the spread of HIV are biologically and sociologically complex. Mathematical models allow us to organize our knowledge into a coherent picture and examine the logical consequences, therefore they have the potential to be extremely useful in the search to control this disease. 24 refs., 3 figs.« less

Epigenetic regulation of HIV, AIDS, and AIDS-related malignancies.

Verma, Mukesh

2015-01-01

Although epigenetics is not a new field, its implications for acquired immunodeficiency syndrome (AIDS) research have not been explored fully. To develop therapeutic and preventive approaches against the human immunodeficiency virus (HIV) and AIDS, it is essential to understand the mechanisms of interaction between the virus and the host, involvement of genetic and epigenetic mechanisms, characterization of viral reservoirs, and factors influencing the latency of the virus. Both methylation of viral genes and histone modifications contribute to initiating and maintaining latency and, depending on the context, triggering viral gene repression or expression. This chapter discusses progress made at the National Institutes of Health (NIH), recommendations from the International AIDS Society Scientific Working Group on HIV Cure, and underlying epigenetic regulation. A number of epigenetic inhibitors have shown potential in treating AIDS-related malignancies. Epigenetic drugs approved by the US Food and Drug Administration and their implications for the eradication of HIV/AIDS and AIDS-related malignancies also are discussed.Past and current progress in developing treatments and understanding the molecular mechanisms of AIDS and HIV infection has greatly improved patient survival. However, increased survival has been coupled with the development of cancer at higher rates than those observed among the HIV/AIDS-negative population. During the early days of the AIDS epidemic, the most frequent AIDS-defining malignancies were Kaposi's sarcoma and non-Hodgkin lymphoma (NHL). Now, with increased survival as the result of widespread use in the developed world of highly active antiretroviral therapy (HAART), non-AIDS defining cancers (i.e., anal, skin, and lung cancers, and Hodgkin disease) are on the increase in HIV-infected populations. The current status of AIDS-related malignancies also is discussed.

Influence of Emotionally Charged Information on Category-Based Induction

PubMed Central

Zhu, Jennifer; Murphy, Gregory L.

2013-01-01

Categories help us make predictions, or inductions, about new objects. However, we cannot always be certain that a novel object belongs to the category we are using to make predictions. In such cases, people should use multiple categories to make inductions. Past research finds that people often use only the most likely category to make inductions, even if it is not certain. In two experiments, subjects read stories and answered questions about items whose categorization was uncertain. In Experiment 1, the less likely category was either emotionally neutral or dangerous (emotionally charged or likely to pose a threat). Subjects used multiple categories in induction when one of the categories was dangerous but not when they were all neutral. In Experiment 2, the most likely category was dangerous. Here, people used multiple categories, but there was also an effect of avoidance, in which people denied that dangerous categories were the most likely. The attention-grabbing power of dangerous categories may be balanced by a higher-level strategy to reject them. PMID:23372700

Aversive Learning Modulates Cortical Representations of Object Categories

PubMed Central

Dunsmoor, Joseph E.; Kragel, Philip A.; Martin, Alex; LaBar, Kevin S.

2014-01-01

Experimental studies of conditioned learning reveal activity changes in the amygdala and unimodal sensory cortex underlying fear acquisition to simple stimuli. However, real-world fears typically involve complex stimuli represented at the category level. A consequence of category-level representations of threat is that aversive experiences with particular category members may lead one to infer that related exemplars likewise pose a threat, despite variations in physical form. Here, we examined the effect of category-level representations of threat on human brain activation using 2 superordinate categories (animals and tools) as conditioned stimuli. Hemodynamic activity in the amygdala and category-selective cortex was modulated by the reinforcement contingency, leading to widespread fear of different exemplars from the reinforced category. Multivariate representational similarity analyses revealed that activity patterns in the amygdala and object-selective cortex were more similar among exemplars from the threat versus safe category. Learning to fear animate objects was additionally characterized by enhanced functional coupling between the amygdala and fusiform gyrus. Finally, hippocampal activity co-varied with object typicality and amygdala activation early during training. These findings provide novel evidence that aversive learning can modulate category-level representations of object concepts, thereby enabling individuals to express fear to a range of related stimuli.

Section on AIDS: the politics of survival. Introduction.

PubMed

Krieger, N; Margo, G

1990-01-01

In one short decade, the politics of AIDS has become the politics of survival. In a world whose social order is changing before our eyes, AIDS insistently brings new meaning to the age-old question of what it is we must do to survive--as individuals, as families, as communities, as nations, as members of an interdependent world. The goal of this Special Section is to promote frank discussion, from an explicitly progressive perspective, of what it will take to stop the AIDS epidemic and deal with the devastation it has already wrought. Articles by AIDS researchers, service providers, and activists from around the world will address the numerous social, political, economic, and cultural factors that affect both the spread of AIDS and the social response to the epidemic. Topics to be considered in this and future issues of the Journal include: AIDS and community survival in the United States; women and AIDS, particularly in economically underdeveloped countries; the politics and economics of AIDS interventions in Latin America and the Caribbean; and the growing international AIDS industry.

Asia: fighting HIV / AIDS makes business sense.

PubMed

1999-11-15

Three Asian companies are investing in HIV/AIDS education and prevention schemes because they are starting to feel the effects of the HIV/AIDS pandemic on their workforces. A total of 17 companies from the region signed a document in the Fifth International Congress on AIDS in Asia and the Pacific committing to the fight against AIDS. The group said that effective workplace programs can prevent an increase in absenteeism, health care costs and labor turnover, a decrease in productivity, loss of experienced personnel and the need for increased resources to hire and retrain replacements. American International Assurance in Thailand accredits companies with effective HIV/AIDS campaigns in the workplace and gives them a 5-10% discount on premiums on group life insurance policies. At Freeport Mining in Indonesia, an HIV/AIDS campaign markedly improved condom usage rates and decreased incidence of sexually transmitted diseases (STDs) among workers. Meanwhile, India's Tata Tea Limited expanded its health services to include surveys, training, education, and counseling on HIV/AIDS and STDs.

AIDS in Mexican prisons.

PubMed

Olivero, J M; Roberts, J B

1995-01-01

The human rights organization Americas Watch, which toured Mexican prisons, reported in 1991 that all prisoners with HIV infection in the Mexico City area were housed in a single AIDS ward in Santa Marta Prison. In 1991, the 16-bed facility had 15 patients; in 1993, this number had increased by 5. In Mexico City, with 3 prisons holding over 2000 male adults each, there were only 20 known infected prisoners in the AIDS ward at Santa Marta. In 1991, authorities at Matamoros, in the state of Tamaulipas, insisted that none of their inmates had ever been diagnosed as infected with HIV. The prison physician at Reynosa indicated that only 2 inmates since 1985 had ever been diagnosed as infected. In 1992, the prison in Saltillo, in the state of Coahuila, reported that here had yet to be a single positive test for HIV. The prison at Reynosa held 1500 people and only 2 inmates were diagnosed as having AIDS between 1985 and 1991. Prisons at Matamoros and Saltillo held similar numbers but had no experience of infected inmates. A survey of 2 prisons in the state of Tamaulipas indicates that around 12% of the population may use IV drugs, and 9% indicate sharing needles. It is possible for prisoners to die of diseases like pneumonia, associated with AIDS, without the connection to AIDS being diagnosed. Each state, and possibly each prison in Mexico, has its own particular AIDS policies. Santa Marta was the single facility in Mexico City used to house AIDS-infected prisoners, who were segregated. Finally, the prison at Saltillo required all women entering the facility to have a medical examination, including a test for HIV. High-level prison personnel have demonstrated ignorance and fear of AIDS and intolerance of infected prisoners. Mexico must reassess the need to provide adequate medical care to offenders who are sick and dying behind bars.

2012-01-01

Purpose To compare demographic characteristics and predictors of survival of rural residents diagnosed with acquired immunodeficiency syndrome (AIDS) with those of urban residents. Methods Florida surveillance data for people diagnosed with AIDS during 1993–2007 were merged with 2000 Census data using ZIP code tabulation areas (ZCTA). Rural status was classified based on the ZCTA’s rural-urban commuting area classification. Survival rates were compared between rural and urban areas using survival curves and Cox proportional hazards models controlling for demographic, clinical, and area-level socioeconomic and health care access factors. Findings Of the 73,590 people diagnosed with AIDS, 1,991 (2.7%) resided in rural areas. People in the most recent rural cohorts were more likely than those in earlier cohorts to be female, non-Hispanic black, older, and have a reported transmission mode of heterosexual sex. There were no statistically significant differences in the 3-, 5-, or 10-year survival rates between rural and urban residents. Older age at the time of diagnosis, diagnosis during the 1993–1995 period, other/unknown transmission mode, and lower CD4 count/percent categories were associated with lower survival in both rural and urban areas. In urban areas only, being non-Hispanic black or Hispanic, being US born, more poverty, less community social support, and lower physician density were also associated with lower survival. Conclusions In rural Florida, the demographic characteristics of people diagnosed with AIDS have been changing, which may necessitate modifications in the delivery of AIDS-related services. Rural residents diagnosed with AIDS did not have a significant survival disadvantage relative to urban residents. PMID:23802929

Diagnostic Categories in Autobiographical Accounts of Illness.

PubMed

Kelly, Michael P

2015-01-01

Working within frameworks drawn from the writings of Immanuel Kant, Alfred Schutz, and Kenneth Burke, this article examines the role that diagnostic categories play in autobiographical accounts of illness, with a special focus on chronic disease. Four lay diagnostic categories, each with different connections to formal medical diagnostic categories, serve as typifications to make sense of the way the lifeworld changes over the course of chronic illness. These diagnostic categories are used in conjunction with another set of typifications: lay epidemiologies, lay etiologies, lay prognostics, and lay therapeutics. Together these serve to construct and reconstruct the self at the center of the lifeworld. Embedded within the lay diagnostic categories are narratives of progression, regression, or stability, forms of typification derived from literary and storytelling genres. These narratives are developed by the self in autobiographical accounts of illness.

Risk management strategies in the Physicians' Desk Reference product labels for pregnancy category X drugs.

Drugs that carry a concern for teratogenicity are often classified as pregnancy category X in the drug label and contraindicated for use during pregnancy. Many drug labels can be found in the Physicians' Desk Reference (PDR), a widely used source of drug information by American clinicians and patients. To review product labelling in the electronic PDR for the pregnancy category X products for pregnancy prevention risk management components in labelling. The electronic version of the 2001 and 2002 PDR was searched for 'pregnancy category X' products using the full text search feature. All product labels identified were retrieved and reviewed for trade name, generic name, manufacturer and indication. Product labels were manually searched for any pregnancy prevention risk management strategies included in labelling. Those labels that had specific pregnancy prevention risk management strategies were further evaluated. One hundred and seventeen pregnancy category X products were obtained from 2249 products searched in the 2001 PDR database and 124 pregnancy category X products were obtained from the 2150 products in the 2002 PDR database. All pregnancy category X products identified were drug products. The label/package insert for each drug was reviewed to identify risk management strategies for pregnancy prevention. The majority of the labels include as the sole risk management strategy either a black box warning and/or a contraindication for use in women who are or may become pregnant. Only 13 drugs contained specific pregnancy prevention risk management strategies in the label directing the clinician and/or patient, e.g. frequency of pregnancy testing, number and type of contraception methods. Two drugs, bexarotene capsules and gel, were only included in the 2001 PDR. Three drugs, isotretinoin, acitretin, and thalidomide, have formal pregnancy prevention risk management programmes. This study demonstrates the varied risk management approaches in labelling for

Ad hoc categories and false memories: Memory illusions for categories created on-the-spot.

PubMed

Soro, Jerônimo C; Ferreira, Mário B; Semin, Gün R; Mata, André; Carneiro, Paula

2017-11-01

Three experiments were designed to test whether experimentally created ad hoc associative networks evoke false memories. We used the DRM (Deese, Roediger, McDermott) paradigm with lists of ad hoc categories composed of exemplars aggregated toward specific goals (e.g., going for a picnic) that do not share any consistent set of features. Experiment 1 revealed considerable levels of false recognitions of critical words from ad hoc categories. False recognitions occurred even when the lists were presented without an organizing theme (i.e., the category's label). Experiments 1 and 2 tested whether (a) the ease of identifying the categories' themes, and (b) the lists' backward associative strength could be driving the effect. List identifiability did not correlate with false recognition, and the effect remained even when backward associative strength was controlled for. Experiment 3 manipulated the distractor items in the recognition task to address the hypothesis that the salience of unrelated items could be facilitating the occurrence of the phenomenon. The effect remained when controlling for this source of facilitation. These results have implications for assumptions made by theories of false memories, namely the preexistence of associations in the activation-monitoring framework and the central role of gist extraction in fuzzy-trace theory, while providing evidence of the occurrence of false memories for more dynamic and context-dependent knowledge structures.

On the classification of weakly integral modular categories

DOE Office of Scientific and Technical Information (OSTI.GOV)

Bruillard, Paul; Galindo, César; Ng, Siu-Hung

In this paper we classify all modular categories of dimension 4m, where m is an odd square-free integer, and all rank 6 and rank 7 weakly integral modular categories. This completes the classification of weakly integral modular categories through rank 7. In particular, our results imply that all integral modular categories of rank at most 7 are pointed (that is, every simple object has dimension 1). All the non-integral (but weakly integral) modular categories of ranks 6 and 7 have dimension 4m, with m an odd square free integer, so their classification is an application of our main result. Themore » classification of rank 7 integral modular categories is facilitated by an analysis of the two group actions on modular categories: the Galois group of the field generated by the entries of the S-matrix and the group of invertible isomorphism classes of objects. We derive some valuable arithmetic consequences from these actions.« less

In formulating the second national strategic plan for prevention of HIV/AIDS in the Islamic Republic of Iran a more evidence-based approach was needed. This paper reports on a systematic review of the local evidence about the determinants of HIV/AIDS transmission in 3 categories: poor knowledge and negative attitudes about HIV transmission; injection drug use; and sexual promiscuity. Of 93 reports reviewed, 53 met the inclusion criteria. Information about the prevalence and magnitude of effect for the 3 risk determinants at the national and regional level was scarce. Heterogeneity between studies, even in the same sub-population, was significant. An improved research base and better sharing of information are needed within countries of the Eastern Mediterranean Region.

Metacognitive Control of Categorial Neurobehavioral Decision Systems

PubMed Central

Foxall, Gordon R.

2016-01-01

The competing neuro-behavioral decision systems (CNDS) model proposes that the degree to which an individual discounts the future is a function of the relative hyperactivity of an impulsive system based on the limbic and paralimbic brain regions and the relative hypoactivity of an executive system based in prefrontal cortex (PFC). The model depicts the relationship between these categorial systems in terms of the antipodal neurophysiological, behavioral, and decision (cognitive) functions that engender normal and addictive responding. However, a case may be made for construing several components of the impulsive and executive systems depicted in the model as categories (elements) of additional systems that are concerned with the metacognitive control of behavior. Hence, this paper proposes a category-based structure for understanding the effects on behavior of CNDS, which includes not only the impulsive and executive systems of the basic model but a superordinate level of reflective or rational decision-making. Following recent developments in the modeling of cognitive control which contrasts Type 1 (rapid, autonomous, parallel) processing with Type 2 (slower, computationally demanding, sequential) processing, the proposed model incorporates an arena in which the potentially conflicting imperatives of impulsive and executive systems are examined and from which a more appropriate behavioral response than impulsive choice emerges. This configuration suggests a forum in which the interaction of picoeconomic interests, which provide a cognitive dimension for CNDS, can be conceptualized. This proposition is examined in light of the resolution of conflict by means of bundling. PMID:26925004

Classification versus inference learning contrasted with real-world categories.

PubMed

Jones, Erin L; Ross, Brian H

2011-07-01

Categories are learned and used in a variety of ways, but the research focus has been on classification learning. Recent work contrasting classification with inference learning of categories found important later differences in category performance. However, theoretical accounts differ on whether this is due to an inherent difference between the tasks or to the implementation decisions. The inherent-difference explanation argues that inference learners focus on the internal structure of the categories--what each category is like--while classification learners focus on diagnostic information to predict category membership. In two experiments, using real-world categories and controlling for earlier methodological differences, inference learners learned more about what each category was like than did classification learners, as evidenced by higher performance on a novel classification test. These results suggest that there is an inherent difference between learning new categories by classifying an item versus inferring a feature.

Modeling and Predicting Hearing Aid Outcome

PubMed Central

Humes, Larry E.

2003-01-01

Following a brief tutorial on the application of factor analysis to hearing aid outcome measures, three studies of hearing aid outcome measures in elderly adults are presented and analyzed. Two of the studies were completed at Indiana University (IU-1 and IU-2), and one was a collaborative multisite study by the Veterans Administration and the National Institute of Deafness and other Communication Disorders (NIDCD/VA). IU-1 measured hearing aid outcome in 173 elderly wearers of single-channel, linear, in-the-ear hearing aids with output-limiting compression, whereas IU-2 obtained the same extensive set of outcome measures from 53 elderly wearers of two-channel, wide-dynamic-range compression, in-the-canal hearing aids. In the NIDCD/VA study, 333 to 338 participants wore three single-channel circuits in succession, with each circuit housed within an in-the-ear shell. The three circuits included in that study and in this analysis were: (1) linear with peak clipping, (2) linear with output-limiting compression, and (3) single-channel, wide-dynamic-range compression. Evaluation of the many outcome measures completed in each study using principal components factor analysis revealed that from three (both IU studies) to five (NIDCD/VA study) principal components captured the individual differences in hearing aid outcome. This was independent of hearing aid type (in-the-ear or in-the-canal) and circuitry. Subsequent multiple regression analyses of individual differences in performance along each dimension of hearing aid outcome revealed that these individual differences could be accounted for reasonably well by various prefit variables for some dimensions of outcome, but not others. In general, measures of speech recognition performance were well accounted for by prefit measures, with the best predictors being hearing loss, cognitive performance, and age. Measures of hearing aid usage were less well accounted for by prefit measures, with the most accurate predictor of

AIDS: there's hope.

1993-06-01

In 1993, 10 years after realizing that AIDS posed a threat to the future of mankind, social mobilization will improve the odds against AIDS. The objective is to create awareness about the virus, and to affect positive behavioral change through advocacy, communication, and grass-roots actions. The first goal is to change the societal attitude about the status of youth and women in order to understand that gender inequality fuels the pandemic. They are the most vulnerable groups, therefore their economic and social power must be improved. The Convention on the Rights of the Child and the Convention on the Elimination of All Forms of Discrimination against Women constitute a platform for broader action by governmental, nongovernmental, and religious institutions. In addition, these organizations need strong allies in society: 1) the media, which can communicate the importance of youth, women, and attitudes in the epidemic; 2) religious leaders, who can be powerful sources of advocacy for change in attitudes as well as support and care for AIDS-affected individuals and families; 3) policy makers, who can be crucial in changing existing policies and altering the allocation of government resources to youth and women; 4) human rights organizations, which play an important role in promoting the concept of health as a human right and for enhancing the understanding of AIDS in the context of discrimination and poverty; 5) the private sector, including commerce and industry, which can promote changes in attitude within the work force and AIDS prevention initiatives; and 6) parent-teacher groups and models for youth, who can educate them about socially acceptable and unacceptable behavior and can empower them to make responsible behavior choices.

The Greater Involvement of People Living with AIDS principle: theory versus practice in Ontario's HIV/AIDS community-based research sector.

Drawing on the Greater Involvement of People with HIV/AIDS (GIPA) principle, the HIV/AIDS movement began to "democratize" research in Canada in the mid-1990s. To date, there is little evidence about the success of the community-based research (CBR) movement in relation to the implementation of GIPA. We draw on findings from a larger study examining barriers and facilitating factors in relation to HIV-related CBR in Ontario, Canada. An online survey was completed by 39 senior managers in Ontario AIDS service organizations (ASOs). Twenty-five in-depth, semi-structured interviews were then conducted to further explore the survey findings. Survey respondents reported that, compared to researchers and frontline service providers, people living with HIV/AIDS (PLWHA) tended to be the least involved in all stages (input, process and outcome) of CBR projects. AIDS service organizations with a mandate that included serving rural and urban communities reported even lower levels of PLWHA involvement in CBR. Qualitative data reveal complex barriers that make meaningful PLWHA engagement in CBR difficult, including: HIV-related stigma; health-related challenges; "credentialism"; lack of capacity to engage in research; other issues taking priority; and mistrust of researchers. Facilitating factors included valuing lived experience; training and mentoring opportunities; financial compensation; trust building; and accommodating PLWHA's needs. While there is strong support for the GIPA principles in theory, practice lags far behind.

Even if references to the tools required to intervene after an accident can be found in the works of Bernardino Ramazzini (1633-1714) or Johann Peter Frank (1745-1821), it was only with the development of industrial manufacturing that the need to study means to prevent and intervene in cases of accident became evident. In October 1894 the III Congrés International des Accidents du Travail et des Assurances Sociales was held in Milan. The following year, the Milanese trade union movement acknowledged the necessity to address the problem of industrial accidents. In 1896 the Association for Medical Assistance in  Industrial Accidents was founded in Milan. A specific medical institute was set up, appropriate first aid tools were collected and first aid rooms in the main Milanese factories were inaugurated. Nevertheless, few data seem to be available regarding the manufacture and use of this equipment in industry. We analyzed more than fifty catalogs of European industrial products, between 1843 and 1914, to study the evolution of first aid equipment for industrial use. They reflect and attest to the evolution of medicine and surgery, although some models seem to be related to certain industrial categories (railways, electrical appliances), some were similar to ordinary first aid boxes, others were strictly related to surgery; some could only be used by physicians, and others only by workers. Identification, conservation, and reappraisal of these tools is essential for historians of occupational health because these objects were normally not preserved. The catalogues of industrial production are also precious sources, since they are rarely preserved in public libraries and deserve to be used for historical studies.

Educating Brazilian workers about AIDS.

PubMed

1991-12-01

This article contains a the script for a slide-tape presentation entitled Working Against AIDS, a presentation developed by the Brazil Family Planning Association (BEMFAM) which is designed to debunk common misconceptions about the disease. This audio-visual, which targets Brazilian workers, can be used during talks, seminars, and meetings. A discussion of the issues involved usually follows the presentation of Working Against AIDS. The presentation contains 30 illustrated slides (these are included in the article). The presentation begins by explaining that much of the information concerning AIDS is prejudicial and misleading. The next few slides point out some of the common misconceptions about AIDS, such as claims denying the existence of the disease, or suggestions that only homosexuals and prostitutes are at risk. The presentation then goes on to explain the ways in which the virus can and cannot be transmitted. Then it discusses how the virus destroys the body's natural defenses and explains the ensuing symptoms. Slides 14 and 15 point out that no cure yet exists for AIDS, making prevention essential. Slides 16-23 explain what actions are considered to be high risk and which ones do not entail risk. Noting that AIDS can be prevented, slide 24 says that the disease should not present an obstacle to spontaneous manifestations of human relations. The next slide explains that condoms should always be used when having sex with someone who could be infected with AIDS. Finally slides 26-30 demonstrate the proper way to use and dispose of a condom.

In formative work, a decision aid was designed to facilitate patient-clinician discussion regarding three options: continue smoking, attempt a period of temporary abstinence, and attempt to quit smoking for good. A randomized, two-group pilot study was then conducted in smokers evaluated in preparation for elective surgery in a preoperative clinic to test the hypothesis that the decision aid would improve measures of decisional quality compared with usual care. The final decision aid consisted of three laminated cards. The front of each card included a colorful graphic describing each choice; the reverse including two to three pros and cons for each decision, a simple graphic illustrating the effects of smoking on the body, and a motivational phrase. In the randomized trial of 130 patients, the decision aid significantly (P < 0.05) improved measures of decisional quality and patient involvement in decision making (Cohen's d effect sizes of 0.76 and 1.20 for the Decisional Conflict Scale and Observing PatienT involvement In decisiON-making scale, respectively). However, the decision aid did not affect any aspect of perioperative smoking behavior, including the distribution of or adherence to choices. Although the use of a decision aid to facilitate clinician-patient discussions regarding tobacco use around the time of surgery substantially improved measures of decisional quality, it alone did not change perioperative tobacco use behavior.

Behavior-based aggregation of land categories for temporal change analysis

Comparison between two time points of the same categorical variable for the same study extent can reveal changes among categories over time, such as transitions among land categories. If many categories exist, then analysis can be difficult to interpret. Category aggregation is the procedure that combines two or more categories to create a single broader category. Aggregation can simplify interpretation, and can also influence the sizes and types of changes. Some classifications have an a priori hierarchy to facilitate aggregation, but an a priori aggregation might make researchers blind to important category dynamics. We created an algorithm to aggregate categories in a sequence of steps based on the categories' behaviors in terms of gross losses and gross gains. The behavior-based algorithm aggregates net gaining categories with net gaining categories and aggregates net losing categories with net losing categories, but never aggregates a net gaining category with a net losing category. The behavior-based algorithm at each step in the sequence maintains net change and maximizes swap change. We present a case study where data from 2001 and 2006 for 64 land categories indicate change on 17% of the study extent. The behavior-based algorithm produces a set of 10 categories that maintains nearly the original amount of change. In contrast, an a priori aggregation produces 10 categories while reducing the change to 9%. We offer a free computer program to perform the behavior-based aggregation.

Psychopathic disorder: a category mistake?

PubMed Central

Holmes, C A

1991-01-01

Although the concept of psychopathy retains its currency in British psychiatry, apparently being meaningful as well as useful to practitioners (1), it is often taken to refer to a purely legal category with social control functions rather than a medical diagnosis with treatment implications. I wish, in this brief article, to suggest that it is essentially, and most usefully, an ethical category which stands outside the diagnostic framework of present-day psychiatry. PMID:1870086

Objective To assess the relationship between parental HIV/AIDS and psychosocial adjustment of children in rural central China. Methods Participants included 296 double AIDS orphans (children who had lost both their parents to AIDS), 459 single orphans (children who had lost one parent to AIDS), 466 vulnerable children who lived with HIV-infected parents, and 404 comparison children who did not experience HIV/AIDS-related illness and death in their families. The measures included depressive symptoms, loneliness, self-esteem, future expectations, hopefulness about the future, and perceived control over the future. Results AIDS orphans and vulnerable children consistently demonstrated poorer psychosocial adjustment than comparison children in the same community. The level of psychosocial adjustment was similar between single orphans and double orphans, but differed by care arrangement among double orphans. Conclusion The findings underscore the urgency and importance of culturally and developmentally appropriate intervention efforts targeting psychosocial problems among children affected by AIDS and call for more exploration of risk and resilience factors, both individual and contextual, affecting the psychosocial wellbeing of these children.

Category-contingent face adaptation for novel colour categories: Contingent effects are seen only after social or meaningful labelling.

PubMed

Little, Anthony C; DeBruine, Lisa M; Jones, Benedict C

2011-01-01

A face appears normal when it approximates the average of a population. Consequently, exposure to faces biases perceptions of subsequently viewed faces such that faces similar to those recently seen are perceived as more normal. Simultaneously inducing such aftereffects in opposite directions for two groups of faces indicates somewhat discrete representations for those groups. Here we examine how labelling influences the perception of category in faces differing in colour. We show category-contingent aftereffects following exposure to faces differing in eye spacing (wide versus narrow) for blue versus red faces when such groups are consistently labelled with socially meaningful labels (Extravert versus Introvert; Soldier versus Builder). Category-contingent aftereffects were not seen using identical methodology when labels were not meaningful or were absent. These data suggest that human representations of faces can be rapidly tuned to code for meaningful social categories and that such tuning requires both a label and an associated visual difference. Results highlight the flexibility of the cognitive visual system to discriminate categories even in adulthood. Copyright © 2010 Elsevier B.V. All rights reserved.

First-pass selectivity for semantic categories in human anteroventral temporal lobe

How the brain encodes the semantic concepts represented by words is a fundamental question in cognitive neuroscience. Hemodynamic neuroimaging studies have robustly shown that different areas of posteroventral temporal lobe are selectively activated by images of animals versus manmade objects. Selective responses in these areas to words representing animals versus objects are sometimes also seen, but they are task-dependent, suggesting that posteroventral temporal cortex may encode visual categories, while more anterior areas encode semantic categories. Here, using the spatiotemporal resolution provided by intracranial macroelectrode and microelectrode arrays, we report category-selective responses to words representing animals and objects in human anteroventral temporal areas including inferotemporal, perirhinal and entorhinal cortices. This selectivity generalizes across tasks and sensory modalities, suggesting that it represents abstract lexico-semantic categories. Significant category-specific responses are found in measures sensitive to synaptic activity (local field potentials, high gamma power, current sources and sinks) and unit-firing (multi- and single-unit activity). Category-selective responses can occur at short latency, as early as 130ms, in middle cortical layers and thus are extracted in the first-pass of activity through the anteroventral temporal lobe. This activation may provide input to posterior areas for iconic representations when required by the task, as well as to the hippocampal formation for categorical encoding and retrieval of memories, and to the amygdala for emotional associations. More generally, these results support models in which the anteroventral temporal lobe plays a primary role in the semantic representation of words. PMID:22159123

Providing a model of a comprehensive free audiologic program may assist other health care professionals in developing their own similar program. To describe the structure, feasibility, and outcomes of a free subspecialty clinic providing hearing aids to develop a paradigm for other programs interested in implementing similar projects. A retrospective case series was conducted from September 1, 2013, through March 31, 2016. In a partnership between a free independent clinic for indigent patients and an academic medical center, 54 indigent patients were referred to the clinic for audiograms. A total of 50 of these patients had results of audiograms available for review and were therefore included in the study; 34 of these 50 patients were determined to be eligible for hearing aid fitting based on audiometric results. Free audiometric testing, hearing aid fitting, and hearing aid donation. The number of hearing aids donated, number of eligible patients identified, number of patients fitted with hearing aids, and work effort (hours) and start-up costs associated with implementation of this program were quantified. A total of 54 patients (31 women [57.4%] and 23 men [42.6%]; median age, 61 years; range, 33-85 years) had audiograms performed, and 84 hearing aids were donated to the program. The patients were provided with free audiograms, hearing aid molds, and hearing aid programming, as well as follow-up appointments to ensure continued proper functioning of their hearing aids. Since 2013, a total of 34 patients have been determined to be eligible for the free program and were offered hearing aid services. Of these, 20 patients (59%) have been fitted or are being fitted with free hearing aids. The value of services provided is estimated to be $2260 per patient. It is feasible to provide free, comprehensive audiologic care, including hearing aids and fitting, in a well-established, free clinic model.

Observation versus classification in supervised category learning.

PubMed

Levering, Kimery R; Kurtz, Kenneth J

2015-02-01

The traditional supervised classification paradigm encourages learners to acquire only the knowledge needed to predict category membership (a discriminative approach). An alternative that aligns with important aspects of real-world concept formation is learning with a broader focus to acquire knowledge of the internal structure of each category (a generative approach). Our work addresses the impact of a particular component of the traditional classification task: the guess-and-correct cycle. We compare classification learning to a supervised observational learning task in which learners are shown labeled examples but make no classification response. The goals of this work sit at two levels: (1) testing for differences in the nature of the category representations that arise from two basic learning modes; and (2) evaluating the generative/discriminative continuum as a theoretical tool for understand learning modes and their outcomes. Specifically, we view the guess-and-correct cycle as consistent with a more discriminative approach and therefore expected it to lead to narrower category knowledge. Across two experiments, the observational mode led to greater sensitivity to distributional properties of features and correlations between features. We conclude that a relatively subtle procedural difference in supervised category learning substantially impacts what learners come to know about the categories. The results demonstrate the value of the generative/discriminative continuum as a tool for advancing the psychology of category learning and also provide a valuable constraint for formal models and associated theories.

A Comparison of the neural correlates that underlie rule-based and information-integration category learning.

Carpenter, Kathryn L; Wills, Andy J; Benattayallah, Abdelmalek; Milton, Fraser

The influential competition between verbal and implicit systems (COVIS) model proposes that category learning is driven by two competing neural systems-an explicit, verbal, system, and a procedural-based, implicit, system. In the current fMRI study, participants learned either a conjunctive, rule-based (RB), category structure that is believed to engage the explicit system, or an information-integration category structure that is thought to preferentially recruit the implicit system. The RB and information-integration category structures were matched for participant error rate, the number of relevant stimulus dimensions, and category separation. Under these conditions, considerable overlap in brain activation, including the prefrontal cortex, basal ganglia, and the hippocampus, was found between the RB and information-integration category structures. Contrary to the predictions of COVIS, the medial temporal lobes and in particular the hippocampus, key regions for explicit memory, were found to be more active in the information-integration condition than in the RB condition. No regions were more activated in RB than information-integration category learning. The implications of these results for theories of category learning are discussed.

A project in Zambia: talking to children about AIDS.

PubMed

Baker, K

1988-09-01

Early in 1987, it became clear to this individual that children were a high priority group for Acquired Immune Deficiency Syndrome (AIDS) education. Preparation for providing AIDS education in Zambia included reading as much as possible about AIDS and AIDS education in schools, contacting the Health Education Unit at the Ministry of Health for their permission and advice, and making posters and preparing a list of 10 basic questions about AIDS. The 1st talks were at a boys' technical school and a large girls' day school. Following an introduction of the subject, the format included: a 10-minute quiz with students writing down their answers; a 35-40 minute talk, using posters as visual aids; a 20-30 minute open question time; and a repeat of the same quiz as a form of "posttest." The students responded positively, and there was a substantial increase in the percentage of correct answers after each talk. Subsequently, talks were given in other Lusaka secondary schools. After the 1st few talks, the pretest and posttest was discontinued as it was considered preferable to spend more time answering the students' questions. The talks varied depending on the audience, but posters were always included as visual aids. Initially, this AIDS education effort was voluntary and unfunded. Subsequently, and as the work grew, NORAD funded the project, paying for duplicating and printing as well as a salary on an hourly basis. A booklet on AIDS for secondary schools has been written and duplicated and accepted by the Intersectorial Committee on AIDS Health Education with minor changes. Late in 1987, the booklet was rewritten totally and expanded, with numerous illustrations. Throughout the booklet, human immunodeficiency virus (HIV) is carefully differentiated from AIDS disease. Talks also have been initiated at the Upper Primary School level. The format has been altered somewhat for these younger children as they tend to be noisy and excited. The primary project planned for 1988 is

Social categories as markers of intrinsic interpersonal obligations.

PubMed

Rhodes, Marjorie; Chalik, Lisa

2013-06-01

Social categorization is an early-developing feature of human social cognition, yet the role that social categories play in children's understanding of and predictions about human behavior has been unclear. In the studies reported here, we tested whether a foundational functional role of social categories is to mark people as intrinsically obligated to one another (e.g., obligated to protect rather than harm). In three studies, children (aged 3-9, N = 124) viewed only within-category harm as violating intrinsic obligations; in contrast, they viewed between-category harm as violating extrinsic obligations defined by explicit rules. These data indicate that children view social categories as marking patterns of intrinsic interpersonal obligations, suggesting that a key function of social categories is to support inferences about how people will relate to members of their own and other groups.

Evaluation of the British Columbia AIDS Information Line.

Parsons, D C; Bell, M A; Gilchrist, L D

1991-01-01

We evaluated implementation of the British Columbia AIDS Information Line during its initial 15 weeks of operation. Data collected during daily operation of the line included call frequency, caller characteristics, response patterns, caller concerns and community referrals. Information on activities and resources required to implement the AIDS Line was also assembled. The study concluded that the advertising campaign sponsored by the provincial government and other AIDS-related media events had a strong impact on the frequency of calls made to the AIDS Line. However, the effect of both advertising and media events was of relatively short duration, suggesting that utilization of an AIDS information line is dependent on continuing promotional activities. The evaluation results demonstrate the importance of continuous collection of data online utilization, to track public awareness of and response to AIDS-related issues, and to facilitate planning of public education.

'Low-hanging fruit': counting and accounting for children in PEPFAR-funded HIV/AIDS programmes in South Africa.

PubMed

Reynolds, Lindsey J

2014-01-01

The article traces the social life of a policy that aimed to define and circumscribe the ambiguous and contested category of 'orphaned and vulnerable children' (or OVC) in South Africa at the height of the 'emergency response' to HIV/AIDS. Drawing on several months of institutional ethnographic research conducted over the course of five years with South African organisations receiving funding from the US President's Emergency Plan for AIDS Relief to provide services to 'OVC', the project interrogates the influence of governmental forms of counting and accounting on health policy and practice in South Africa. Focusing on the experiences of one organisation, the article describes a process of policy 'translation' typified by a series of disconnects between the intentions of a policy and the exigencies of implementation, structured by the ambiguous and flexible nature of the 'OVC' category. In this context, the article argues that the uncertainty produced by the implementation of the guidelines was not simply an artefact of a poorly designed policy, but rather signals an underlying epistemological tension in the practice of 'global health', in which quantitative metrics designed for monitoring and evaluation are often incapable of approximating the complexities of everyday life.

To investigate clinical manifestations and diagnostic difficulties in patients with HIV/AIDS in the practice of therapeutic units of a multidisciplinary hospital. The investigation included 65 HIV/AIDS patients admitted to the therapy units of a Saratov Regional clinical hospital in 2007 to 2011. The clinical features of HIV/AIDS, immunological status, and viral load were studied. The structure of the clinical manifestation of HIV/AIDS showed a preponderance of lung injury in 45 (69%) patients. There were hematological disorders in 38 (58%) patients and nephropathy in 33 (51 %); 11 (17%) patients were diagnosed with infective endocarditis. Rheumatic symptoms and syndromes mimicking HIV/AIDS were found in 10 (15.4%) patients. The degree of immune disorders was most severe in patients with pulmonary dissemination and rheumatic masks and mutually related to the rate of cutaneous manifestations. The specific features of lung injury, infective endocarditis, pulmonary hypertension, rheumatic symptoms, and kidney injury were discussed in HIV/AIDS patients having different causes for admission to specialized therapy units. In connection with the clinical polymorphism of HIV/AIDS, physicians of all specialties should be alert for the possible clinical manifestations of this disease to timely examine patients.

Learning, retention, and generalization of haptic categories

NASA Astrophysics Data System (ADS)

Do, Phuong T.

This dissertation explored how haptic concepts are learned, retained, and generalized to the same or different modality. Participants learned to classify objects into three categories either visually or haptically via different training procedures, followed by an immediate or delayed transfer test. Experiment I involved visual versus haptic learning and transfer. Intermodal matching between vision and haptics was investigated in Experiment II. Experiments III and IV examined intersensory conflict in within- and between-category bimodal situations to determine the degree of perceptual dominance between sight and touch. Experiment V explored the intramodal relationship between similarity and categorization in a psychological space, as revealed by MDS analysis of similarity judgments. Major findings were: (1) visual examination resulted in relatively higher performance accuracy than haptic learning; (2) systematic training produced better category learning of haptic concepts across all modality conditions; (3) the category prototypes were rated newer than any transfer stimulus followed learning both immediately and after a week delay; and, (4) although they converged at the apex of two transformational trajectories, the category prototypes became more central to their respective categories and increasingly structured as a function of learning. Implications for theories of multimodal similarity and categorization behavior are discussed in terms of discrimination learning, sensory integration, and dominance relation.

Five Spectroscopic Categories of O-Type Candidate GRB Progenitors

NASA Astrophysics Data System (ADS)

Walborn, Nolan R.; Rojas-Montes, Eliceth; Evans, Chris J.; Maíz Apellániz, Jesús; Wade, Gregg A.

2013-06-01

Five categories of peculiar O-type stars in the Galaxy and Magellanic Clouds that each combine three or four of the canonical GRB properties of magnetic fields, high mass, rarity, rapid rotation, and runaway space motions are displayed. (1) The Of?p stars were initially isolated as a peculiar spectroscopic category which was later found to undergo spectacular periodic variations; they are now understood as the most massive oblique magnetic rotators. All five Galactic members plus two related objects now have magnetic field detections, including one of 20 kG, with rotational periods ranging from a week to >50 yrs. There are also three spectroscopic members in the MCs, for which magnetic observations remain to be undertaken. (2) The ONn stars are rapidly rotating, nitrogen-rich, late-O giants at least several of which are runaways. (3) The Onfp stars are another category first described in terms of certain spectral peculiarities; they are now known to be massive, evolved rapid rotators with strong winds, which theoretically should not exist in the single-star regime. Many are in binary systems, perhaps spun up by mass transfer, while others may be mergers, and at least some are runaways. This category calls into question the assumption that GRBs can occur only at low metallicity where weaker winds allow high rotation to be preserved in evolved objects. (4) A population of young extreme rotators, including the two most rapid known at v sin i of 600 km/sec, lies at the peripheries of the 30 Doradus ionizing clusters. Peculiar radial velocities as well as their locations support an ejection hypothesis, currently under further investigation by means of proper motions. (5) At least two extremely massive O2 stars have also been ejected from 30 Doradus, most likely by dynamical processes since there have not yet been any SN in the dense central cluster R136. Presumably all of these stars must reach LBV and/or WR stages before collapsing, so they are not immediate GRB

Prescriptions for contraindicated category X drugs in pregnancy among women enrolled in TennCare.

Filling of prescriptions for medications labelled as category X by the United States Food and Drug Administration (considered to be contraindicated for use in pregnancy) was identified among 95 284 women enrolled in TennCare, Tennessee's programme for Medicaid enrollees and individuals without health insurance. Using administrative claims data, 391 women (4.10/1000) were identified as having filled category X prescriptions during pregnancy. This included 118 women (1.24/1000) who filled prescriptions for non-contraceptive oestrogens, 81 (0.85/1000) for sedatives, and 71 (0.75/1000) for statins. While many women had physician visits with a diagnosis consistent with a possible indication for an individual drug outside of pregnancy, none of these indications is included for use during pregnancy. Older women and disabled women were more likely than younger women (P < 0.0001) and women enrolled for other reasons (P < 0.0001) to fill category X prescriptions. Nearly two-thirds of the 391 women filled prescriptions after clinical signs or pregnancy tests would indicate pregnancy; nearly 40% filled a category X prescription after a pregnancy-related physician visit. Although the absolute rate of category X medication use in pregnancy is low, substantial numbers of women and their fetuses are exposed during pregnancy. Women above the age of 35 years and women enrolled in TennCare because of disabilities were more likely to fill prescriptions for category X medications during pregnancy than others, implying that risk communication to practitioners and women should focus on identification of these women to reduce their risk of exposure.

Perceived importance of church-based assets to HIV/AIDS prevention and control in a Nigerian city.

Aja, Godwin N; Modeste, Naomi N; Lee, Jerry W; Montgomery, Susanne; Belliard, Juan C

This study explored the extent to which church members thought the assets they might have to engage in HIV/AIDS prevention and control activities were important. Eight hundred and thirty members from 83 Christian churches in Aba, Nigeria completed a multi-item survey questionnaire designed to obtain information on the importance they attached to church-based assets relevant to HIV/AIDS prevention and control. The rating of importance of assets was on a scale of 1 to 5. Rating on the importance of assets was highest in the spiritual asset category (mean = 4.20), followed by health education (4.02), capacity building (4.01), social (3.62), and financial assets (3.54). Among the denominational assets, free HIV/AIDS drug donation was rated higher (4.10) than other assets in the subcategories. This study demonstrates the usefulness of ascertaining members' perspectives on the importance of church-based assets and provides a basis for recommendation to health education administrators.

Although studies have shown reductions in mortality from AIDS after the introduction of combination antiretroviral treatment (cART), little is known about cause-specific mortality in low-income settings in the cART era. We explored predictors of AIDS and non-AIDS mortality and compared cause-specific mortality across high-income and low-income settings in the Asia-Pacific region. We followed patients in the Asia Pacific HIV Observational Database from the date they started cART (or cohort enrolment if cART initiation was identified retrospectively), until the date of death or last follow-up visit. Competing risks methods were used to estimate the cumulative incidence, and to investigate predictors, of AIDS and non-AIDS mortality. Of 4252 patients, 215 died; 89 from AIDS, 97 from non-AIDS causes and 29 from unknown causes. Age more than 50 years [hazard ratio 4.29; 95% confidence interval (CI) 2.10-8.79] and CD4 cell counts less than or equal to 100 cells/microl (hazard ratio 8.59; 95% CI 5.66-13.03) were associated with an increased risk of non-AIDS mortality. Risk factors for AIDS mortality included CD4 cell counts less than or equal to 100 cells/microl (hazard ratio 34.97; 95% CI 18.01-67.90) and HIV RNA 10 001 or more (hazard ratio 4.21; 95% CI 2.07-8.55). There was some indication of a lower risk of non-AIDS mortality in Asian high-income, and possibly low-income, countries compared to Australia. Immune deficiency is associated with an increased risk of AIDS and non-AIDS mortality. Older age predicts non-AIDS mortality in the cART era. Less conclusive was the association between country-income level and cause-specific mortality because of the relatively high proportion of unknown causes of death in low-income settings.

McCoy-Sulentic, Miles E.; Kolb, Thomas E.; Merritt, David M.; Palmquist, Emily C.; Ralston, Barbara E.; Sarr, Daniel A.

2017-01-01

Wetland indicator status (WIS) describes the habitat affinity of plant species and is used in wetland delineations and resource inventories. Understanding how species-level functional traits vary across WIS categories may improve designations, elucidate mechanisms of adaptation, and explain habitat optima and niche. We investigated differences in species-level traits of riparian flora across WIS categories, extending their application to indicate hydrologic habitat. We measured or compiled data on specific leaf area (SLA), stem specific gravity (SSG), seed mass, and mature height of 110 plant species that occur along the Colorado River in Grand Canyon, Arizona. Additionally, we measured leaf δ13C, δ15N, % carbon, % nitrogen, and C/N ratio of 56 species with C3 photosynthesis. We asked the following: (i) How do species-level traits vary over WIS categories? (ii) Does the pattern differ between herbaceous and woody species? (iii) How well do multivariate traits define WIS categories? (iv) Which traits are correlated? The largest trait differences among WIS categories for herbaceous species occurred for SSG, seed mass, % leaf carbon and height, and for woody species occurred for height, SSG, and δ13C. SSG increased and height decreased with habitat aridity for both woody and herbaceous species. The δ13C and hence water use efficiency of woody species increased with habitat aridity. Water use efficiency of herbaceous species increased with habitat aridity via greater occurrence of C4 grasses. Multivariate trait assemblages differed among WIS categories. Over all species, SLA was correlated with height, δ13C, % leaf N, and C/N; height was correlated with SSG and % leaf C; SSG was correlated with % leaf C. Adaptations of both herbaceous and woody riparian species to wet, frequently inundated habitats include low-density stem tissue. Adaptations to drier habitats in the riparian zone include short, high-density cavitation-resistant stem tissue, and high water use

AIDS education for a low literate audience in Zambia.

Msimuko, A K

1988-04-01

A workshop funded by the USA Program for Appropriate Technology in Health (PATH) was an effort by Zambia toward prevention and control of AIDS. The lack of educational materials about AIDS for a low-literate audience was the major problem addressed by the workshop. Other problems include the lack of collaborative effort in the development of materials on AIDS, and the lack of skills needed in the development of such materials in Zambia. 1 of the objectives of the workshop was to launch the Planned Parenthood Association of Zambia's (PPAZ) materials development project. The scope of this project includes the production of educational materials on AIDS for low-literate audiences and a counseling handbook for family planning workers. Print materials should be simply written, using words, idioms, and graphics that are familiar to the target audience. Other workshop objectives included the establishment of collaborative relationships between organizations involved in existing AIDS educational activities in Zambia, and the development of practical skills needed to produce print materials. Education was identified as the most important strategy for the prevention and control of AIDS, and PPAZ should be the executing agency of the print materials project. Audience research, using focus group techniques, focus group discussions, behavioral messages, and pretesting of messages, should be the most effective means of reaching targeted audiences. PPAZ is contracted by PATH to begin development of educational materials, and 2 committees have formed to implement the project and to establish interagency collaboration. Audience research was begun between January and March of 1988, focusing on people's beliefs, practices, and ideas about AIDS. The final phase of the project will be the printing, distribution, and use of the AIDS materials and the training of family planning field workers in the proper use of these materials.

The Role of Grammatical Category Information in Spoken Word Retrieval

PubMed Central

Duràn, Carolina Palma; Pillon, Agnesa

2011-01-01

We investigated the role of lexical syntactic information such as grammatical gender and category in spoken word retrieval processes by using a blocking paradigm in picture and written word naming experiments. In Experiments 1, 3, and 4, we found that the naming of target words (nouns) from pictures or written words was faster when these target words were named within a list where only words from the same grammatical category had to be produced (homogeneous category list: all nouns) than when they had to be produced within a list comprising also words from another grammatical category (heterogeneous category list: nouns and verbs). On the other hand, we detected no significant facilitation effect when the target words had to be named within a homogeneous gender list (all masculine nouns) compared to a heterogeneous gender list (both masculine and feminine nouns). In Experiment 2, using the same blocking paradigm by manipulating the semantic category of the items, we found that naming latencies were significantly slower in the semantic category homogeneous in comparison with the semantic category heterogeneous condition. Thus semantic category homogeneity caused an interference, not a facilitation effect like grammatical category homogeneity. Finally, in Experiment 5, nouns in the heterogeneous category condition had to be named just after a verb (category-switching position) or a noun (same-category position). We found a facilitation effect of category homogeneity but no significant effect of position, which showed that the effect of category homogeneity found in Experiments 1, 3, and 4 was not due to a cost of switching between grammatical categories in the heterogeneous grammatical category list. These findings supported the hypothesis that grammatical category information impacts word retrieval processes in speech production, even when words are to be produced in isolation. They are discussed within the context of extant theories of lexical production. PMID

Radiomic modeling of BI-RADS density categories

2017-03-01

Screening mammography is the most effective and low-cost method to date for early cancer detection. Mammographic breast density has been shown to be highly correlated with breast cancer risk. We are developing a radiomic model for BI-RADS density categorization on digital mammography (FFDM) with a supervised machine learning approach. With IRB approval, we retrospectively collected 478 FFDMs from 478 women. As a gold standard, breast density was assessed by an MQSA radiologist based on BI-RADS categories. The raw FFDMs were used for computerized density assessment. The raw FFDM first underwent log-transform to approximate the x-ray sensitometric response, followed by multiscale processing to enhance the fibroglandular densities and parenchymal patterns. Three ROIs were automatically identified based on the keypoint distribution, where the keypoints were obtained as the extrema in the image Gaussian scale-space. A total of 73 features, including intensity and texture features that describe the density and the parenchymal pattern, were extracted from each breast. Our BI-RADS density estimator was constructed by using a random forest classifier. We used a 10-fold cross validation resampling approach to estimate the errors. With the random forest classifier, computerized density categories for 412 of the 478 cases agree with radiologist's assessment (weighted kappa = 0.93). The machine learning method with radiomic features as predictors demonstrated a high accuracy in classifying FFDMs into BI-RADS density categories. Further work is underway to improve our system performance as well as to perform an independent testing using a large unseen FFDM set.

Infinite Index Subfactors and the GICAR Categories

2015-10-01

Given a II1-subfactor of arbitrary index, we show that the rectangular GICAR category, also called the rectangular planar rook category, faithfully embeds as A - A bimodule maps among the bimodules . As a corollary, we get a lower bound on the dimension of the centralizer algebras for infinite index subfactors, and we also get that is nonabelian for , where is the Jones tower for . We also show that the annular GICAR/planar rook category acts as maps amongst the A-central vectors in , although this action may be degenerate. We prove these results in more generality using bimodules. The embedding of the GICAR category builds on work of Connes and Evans, who originally found GICAR algebras inside Temperley-Lieb algebras with finite modulus.

Effects of grammatical categories on children's visual language processing: Evidence from event-related brain potentials.

PubMed

Weber-Fox, Christine; Hart, Laura J; Spruill, John E

2006-07-01

This study examined how school-aged children process different grammatical categories. Event-related brain potentials elicited by words in visually presented sentences were analyzed according to seven grammatical categories with naturally varying characteristics of linguistic functions, semantic features, and quantitative attributes of length and frequency. The categories included nouns, adjectives, verbs, pronouns, conjunctions, prepositions, and articles. The findings indicate that by the age of 9-10 years, children exhibit robust neural indicators differentiating grammatical categories; however, it is also evident that development of language processing is not yet adult-like at this age. The current findings are consistent with the hypothesis that for beginning readers a variety of cues and characteristics interact to affect processing of different grammatical categories and indicate the need to take into account linguistic functions, prosodic salience, and grammatical complexity as they relate to the development of language abilities.

Trends in AIDS incidence and AIDS-related mortality in British Columbia between 1981 and 2013

Background Appropriate use of highly active antiretroviral therapy (HAART) can markedly decrease the risk of progression to acquired immunodeficiency syndrome (AIDS) and of premature mortality. We aimed to characterize the trends between 1981 and 2013 in AIDS-defining illnesses (ADIs) and in the number AIDS-related deaths in British Columbia (BC), Canada. Methods We included data of 3550 HIV-positive individuals, aged 19 years or older, from different administrative databases in BC. We estimated the relative risk of developing an ADI over time using a Negative Binomial model, and we investigated trends in the percentage of all deaths associated with AIDS using generalized additive models. Findings The number of ADIs has decreased dramatically to its lowest level in 2013. The peak of the AIDS epidemic in BC happened in 1994 with 696 ADIs being reported (rate 42 ADIs per 100 person-years). Since 1997, the number of ADIs decreased from 253 (rate 7 per 100 person-years) to 84 cases in 2013 (rate 1 per 100 person-years) (p-value equals to zero for the trend in the number of ADIs). We have also shown that out of 22 ADIs considered, only PCP maintained its prominent ranking (albeit with much reduced overall prevalence). Finally, we observed that over time very few deaths were related to AIDS-related causes, especially in the most recent years. Interpretation We showed that the number of new ADIs and AIDS-related mortality have been decreasing rapidly over time in BC. These results provide further evidence that integrated comprehensive free programs that facilitate testing, and deliver treatment and care to this population can be effective in markedly decreasing AIDS-related morbidity and mortality, thus suggesting that controlling and eventually ending AIDS is possible.

AIDS in contemporary Islamic ethical literature.

PubMed

Francesca, Ersilia

2002-01-01

AIDS has been mentioned in Islamic ethical literature since about 1985 as an illness pertaining to European and American homosexuals. Only since about 1990 has the presence of HIV/AIDS in Islamic countries cast light on the fact that the actual sexual behaviour of the population does not always conform to religious norms. The increase in the numbers of people with HIV has compelled religious leaders to take a stand on sexual practices they consider "deviant", from prostitution to homosexuality and extramarital sex. The aim of this paper is to analyse the attitude of Muslim religious authorities towards individual sexual behaviour and AIDS. It is based mainly on contemporary legal responses that largely provide the necessary information on most of Islamic medical ethics. According to Muslim scholars, AIDS is a warning from God not to indulge in illicit conduct. As a remedy against the spread of AIDS, they encourage compliance with traditional family values and the enhancement of faith and devotion and strongly oppose sex education. They oppose promotion of condoms or any form of safe sex outside of marriage, which they perceive as promoting promiscuity and defiance of divine law. All the above-mentioned arguments are not exhaustive of the Islamic attitude towards AIDS. Some religious groups disagree with such a conservative way of conceiving the fight against AIDS as being antithetical to both men's and women's well-being. They support an alternative view of reproductive health and human rights within the Islamic framework and stress the great tolerance of Islam and why it must include people with HIV and AIDS.

Use of a dementia training designed for nurse aides to train other staff.

Problematic resident behaviors may escalate in long-term care facilities (LTCs). If nurse aides (NAs) are not nearby, the nearest staff to intervene may be non-direct care workers (NDCWs), who have little or no dementia training. This pilot research tested Internet dementia-training program, designed for NAs, on NDCWs in a LTC setting. Sixty-eight NDCWs participated, filling out two baseline surveys at 1-month intervals and a posttest survey after training. The surveys included video-situation testing, items addressing psychosocial constructs associated with behavior change, and measures training-acceptance. Paired t tests showed significant positive effects on measures of knowledge, attitudes, self-efficacy, and behavioral intentions, with small-moderate effect sizes. Nursing staff as well as non-health care workers showed improved scores, and the web-site training program was well received by all participants. These results suggest that Internet training may allow staff development coordinators to conserve limited resources by cross-training of different job categories with the same program.

An investigation of time course of category and semantic priming.

PubMed

Ray, Suchismita

2008-04-01

Low semantically similar exemplars in a category demonstrate the category-priming effect through priming of the category (i.e., exemplar-category-exemplar), whereas high semantically similar exemplars in the same category demonstrate the semantic-priming effect (i.e., direct activation of one high semantically similar exemplar by another). The author asked whether the category- and semantic-priming effects are based on a common memory process. She examined this question by testing the time courses of category- and semantic-priming effects. She tested participants on either category- or semantic-priming paradigm at 2 different time intervals (6 min and 42 min) by using a lexical decision task using exemplars from categories. Results showed that the time course of category priming was different from that of semantic priming. The author concludes that these 2 priming effects are based on 2 separate memory processes.

Aid and good governance: Examining aggregate unintended effects of aid.

PubMed

Dijkstra, Geske

2018-06-01

Although donors generally aim to improve governance in recipient countries by various means, critics claim that the aggregate effect of large aid flows is the deterioration of governance. Aid is said to weaken domestic accountability, sustain authoritarian regimes, increase political instability, weaken government capacities, and increase corruption. Conducting a systematic search in Web of Science, this paper reviews the empirical evidence for these unintended aggregate effects of aid on the political, administrative, and judicial dimensions of good governance. It finds that the negative effects of aid on governance are much exaggerated. The aggregate effect of aid on democracy has become more positive after the Cold War, and the effect of aid on government capacity and on reducing corruption has also improved over time. Furthermore, most studies show a positive effect of aid on political stability. These findings imply that donor intentions matter: donors that are serious about their intended effects on governance are able to mitigate the possible negative unintended effects of their aid.

Color categories affect pre-attentive color perception.

PubMed

Clifford, Alexandra; Holmes, Amanda; Davies, Ian R L; Franklin, Anna

2010-10-01

Categorical perception (CP) of color is the faster and/or more accurate discrimination of colors from different categories than equivalently spaced colors from the same category. Here, we investigate whether color CP at early stages of chromatic processing is independent of top-down modulation from attention. A visual oddball task was employed where frequent and infrequent colored stimuli were either same- or different-category, with chromatic differences equated across conditions. Stimuli were presented peripheral to a central distractor task to elicit an event-related potential (ERP) known as the visual mismatch negativity (vMMN). The vMMN is an index of automatic and pre-attentive visual change detection arising from generating loci in visual cortices. The results revealed a greater vMMN for different-category than same-category change detection when stimuli appeared in the lower visual field, and an absence of attention-related ERP components. The findings provide the first clear evidence for an automatic and pre-attentive categorical code for color. Copyright © 2010 Elsevier B.V. All rights reserved.

A constitution for AIDS.

PubMed

Koshy, L M

1996-01-15

The Indian Health Organization projected the number of deaths per day due to AIDS by the year 2000 at 10,000. An interdisciplinary international conference was held in New Delhi to draft an international law governing the issues related to AIDS. Human freedom and public health policies are the most affected by this disease. In the absence of an international AIDS law, judicial verdicts set precedents and could have serious ramifications. A participant from the John Marshall Law School, Chicago, suggested that instead of making new laws, the existing ones from the colonial past should be repealed. This includes Section 377 of the Indian Penal Code, which provides criminal sanctions against those who indulge in unnatural relations with man, woman, or animal. Penalizing homosexuality will only perpetuate clandestine relations and spread the virus into their families. Another participant seconded this motion stating that even a sex worker must be protected from abuse and indignity. The National AIDS Control Organization responded to the criticism that the government had not utilized all the World Bank funds allocated for anti-AIDS projects. The trends of the epidemic were the most important indicators not just the numbers. In Manipur and Mizoram, infection was almost entirely due to injecting drug use. The Saheli project undertaken in the red-light areas of Bombay encompassed brothel owners and prostitutes, which could be replicated in other areas. Because existing government policies were focusing on prevention, there was no protection of an HIV-infected individual's privacy, one participant from Madras stated. The confidentiality issue was also echoed by a US participant. The New Delhi Declaration and Action Plan on HIV/AIDS was also discussed. It forbids discrimination in employment, education, housing, health care, social security, travel, and marital and reproductive rights. Providing sterile needles and ensuring the safety of the blood supply were other concerns

Burciu, Sebastian, E-mail: sebastian.burciu@imar.ro

In this paper, we describe a Mackey type decomposition for group actions on abelian categories. This allows us to define new Mackey functors which associates to any subgroup the K-theory of the corresponding equivariantized abelian category. In the case of an action by tensor autoequivalences, the Mackey functor at the level of Grothendieck rings has a Green functor structure. As an application we give a description of the Grothendieck rings of equivariantized fusion categories under group actions by tensor autoequivalences on graded fusion categories. In this settings, a new formula for the tensor product of any two simple objects ofmore » an equivariantized fusion category is given, simplifying the fusion formula from Burciu and Natale [J. Math. Phys. 54, 013511 (2013)].« less

Double dissociation of semantic categories in Alzheimer's disease.

Gonnerman, L M; Andersen, E S; Devlin, J T; Kempler, D; Seidenberg, M S

1997-04-01

Data that demonstrate distinct patterns of semantic impairment in Alzheimer's disease (AD) are presented. Findings suggest that while groups of mild-moderate patients may not display category specific impairments, some individual patients do show selective impairment of either natural kinds or artifacts. We present a model of semantic organization in which category specific impairments arise from damage to distributed features underlying different types of categories. We incorporate the crucial notions of intercorrelations and distinguishing features, allowing us to demonstrate (1) how category specific impairments can result from widespread damage and (2) how selective deficits in AD reflect different points in the progression of impairment. The different patterns of impairment arise from an interaction between the nature of the semantic categories and the progression of damage.

Loudness judgment procedures for evaluating hearing aid preselection decisions for severely and profoundly hearing-impaired listeners.

PubMed

Gottermeier, L; De Filippo, C L; Block, M G

1991-08-01

Hearing aid fitting involves a two-phase process of preselection and evaluation (Seewald RC and Ross M. Amplification for the Hearing Impaired 1988:213-271). The purpose of the present study was to examine alternative procedures that clinicians might use in the evaluation phase to verify the adequacy of hearing aid preselection decisions for severely and profoundly hearing-impaired listeners. Bekesy tracking, loudness rating, and conventional bracketing procedures were used to determine threshold, most comfortable listening level, and uncomfortable listening level for 10 hearing-impaired young adults. Stimuli were pulsed pure tones of 500, 1000, and 2000 Hz and filtered words. Means and standard deviations of most comfortable listening levels and uncomfortable listening levels derived from loudness judgments of the 10 subjects showed only nominal differences across procedures. However, correlation analysis (Pearson r) indicated that individuals responded to the three procedures in varying ways, producing different loudness judgments and overall dynamic ranges. Thus, test procedure may influence the clinician's final evaluation of a preselected hearing aid. Initial work suggests that closed-set response categories such as loudness rating can limit measurement variability and potentially guide the clinician's evaluation of hearing aid preselection decisions.

Folstein, Jonathan R; Gauthier, Isabel; Palmeri, Thomas J

2010-01-01

We investigated how mere exposure to complex objects with correlated or uncorrelated object features affects later category learning of new objects not seen during exposure. Correlations among pre-exposed object dimensions influenced later category learning. Unlike other published studies, the collection of pre-exposed objects provided no information regarding the categories to be learned, ruling out unsupervised or incidental category learning during pre-exposure. Instead, results are interpreted with respect to statistical learning mechanisms, providing one of the first demonstrations of how statistical learning can influence visual object learning.

AIDS in South Africa. Puppet power.

PubMed

Friedman, G

1992-01-01

Blacks in South Africa see the government campaign promoting condom use to prevent AIDS as a political ruse to control population growth among Blacks. The City Health Department of Johannesburg does not use a government created poster targeted to Blacks because it implies that only Blacks have AIDS. Even though the number of AIDS cases in South Africa is lower (700 reported cases) than that of its neighbors, the number of HIV infected individuals is growing. So nongovernmental organizations are trying to overcome the division between the government and Blacks by finding alternative ways to stem the AIDS epidemic. The African Research and Educational Puppetry Programme uses Puppets Against AIDS to bridge racial, cultural, language, and educational barriers to thus educate Blacks about AIDS. It not only hopes to create and perform educational and socially valuable theater, but also to rediscover performing arts traditions in southern and central Africa. Since about 76% of the black population in rural South Africa is illiterate, the gray skinned puppets constitute an interactive and inoffensive way to communicate a serious message. Someone demonstrates how to put on a condom using a life size model which induces controversy among physicians and educated whites. Blacks in Johannesburg and surrounding townships are not offended, however. In fact, many have never seen condoms before the demonstration. The puppets emphasize that safe sex and having sex with only 1 partner can stop the spread of AIDS. Each performance also includes live African percussion and music. A narrator distributes free condoms and AIDS information brochures to the audience. Videotapes of each performance are used to evaluate audience reactions. Independent evaluation teams evaluate the impact of the performance. 1-4 day workshops on AIDS, puppet making, story development, and performing skills follow each performance.

When will bigger be (recalled) better? The influence of category size on JOLs depends on test format.

PubMed

Hourihan, Kathleen L; Tullis, Jonathan G

2015-08-01

Although it is well known that organized lists of words (e.g., categories) are recalled better than unrelated lists, little research has examined whether participants can predict how categorical relatedness influences recall. In two experiments, participants studied lists of words that included items from big categories (12 items), small categories (4 items), and unrelated items, and provided immediate JOLs. In Experiment 1, free recall was highest for items from large categories and lowest for unrelated items. Importantly, participants were sensitive to the effects of category size on recall, with JOLs to items from big categories actually increasing over the study list. In Experiment 2, one group of participants was cued to recall all exemplars from the categories in a blocked manner, whereas the other group was cued in a random order. As expected, the random group did not show the recall benefit for big categories over small categories observed in free recall, while the blocked group did. Critically, the pattern of metacognitive judgments closely matched actual cued recall performance. Participants' JOLs were sensitive to the interaction between category size and output order, demonstrating a relatively sophisticated strategy that incorporates the interaction of multiple extrinsic cues in predicting recall.

Employees' perceptions of the Aid-for-AIDS disease-management programme, South Africa.

PubMed

Rothberg, Alan; Van Huyssteen, Karen

2008-11-01

It is estimated that 18-20% of South Africa's more than 5 million HIV-positive individuals are formally employed. Disease management programmes for these employees vary in scope and sophistication, with services provided by the employer, or third-party specialist disease managers, or through medical aid schemes. This study surveyed 215 HIV-positive employees in two organisations contracted to the Aid for AIDS (AfA) disease management programme through their in-house medical aid schemes. The two organisations differed in their overall approach to HIV and AIDS: one mainly relies on on-site access to voluntary counselling and testing (VCT) and AfA's management of registered HIV-positive employees, while the other has invested in and actively developed a comprehensive programme that also extends to families and the community as well as links employees to the AfA programme. Responses received from 28 of the 215 employees surveyed indicate that fear of disclosure of one's HIV status and of stigmatisation are reasons for late registration with the AfA programme or non-utilisation of other available support programmes. Respondents mentioned that confidence in the employer's ability to maintain confidentiality was also an issue. Respondents' important suggestions for change included: a) on-site educational and awareness programmes for management personnel and staff in order to reduce HIV discrimination and stigmatisation; b) information directed at HIV-positive employees publicising the benefits and effectiveness of medical treatment; c) support groups for HIV-positive employees; and d) management personnel to engage with HIV-infected employees who are willing to take an active role in staff education and the development of workplace policies and programmes.

Factor Configurations with Governance as Conditions for Low HIV/AIDS Prevalence in HIV/AIDS Recipient Countries: Fuzzy-set Analysis.

PubMed

Lee, Hwa-Young; Yang, Bong-Min; Kang, Minah

2015-11-01

This paper aims to investigate whether good governance of a recipient country is a necessary condition and what combinations of factors including governance factor are sufficient for low prevalence of HIV/AIDS in HIV/AIDS aid recipient countries during the period of 2002-2010. For this, Fuzzy-set Qualitative Comparative Analysis (QCA) was used. Nine potential attributes for a causal configuration for low HIV/AIDS prevalence were identified through a review of previous studies. For each factor, full membership, full non-membership, and crossover point were specified using both author's knowledge and statistical information of the variables. Calibration and conversion to a fuzzy-set score were conducted using Fs/QCA 2.0 and probabilistic tests for necessary and sufficiency were performed by STATA 11. The result suggested that governance is the necessary condition for low prevalence of HIV/AIDS in a recipient country. From sufficiency test, two pathways were resulted. The low level of governance can lead to low level of HIV/AIDS prevalence when it is combined with other favorable factors, especially, low economic inequality, high economic development and high health expenditure. However, strengthening governance is a more practical measure to keep low prevalence of HIV/AIDS because it is hard to achieve both economic development and economic quality. This study highlights that a comprehensive policy measure is the key for achieving low prevalence of HIV/AIDS in recipient country.

Phase-shifting point diffraction interferometer focus-aid enhanced mask

Naulleau, Patrick

2000-01-01

A phase-shifting point diffraction interferometer system (PS/PDI) employing a PS/PDI mask that includes a PDI focus aid is provided. The PDI focus aid mask includes a large or secondary reference pinhole that is slightly displaced from the true or primary reference pinhole. The secondary pinhole provides a larger capture tolerance for interferometrically performing fine focus. With the focus-aid enhanced mask, conventional methods such as the knife-edge test can be used to perform an initial (or rough) focus and the secondary (large) pinhole is used to perform interferometric fine focus. Once the system is well focused, high accuracy interferometry can be performed using the primary (small) pinhole.

Relatively few reports have investigated the determination and classification of pathogens such as the National Institute of Allergy and Infectious Diseases (NIAID) Category A Bacillus anthracis spores and cells (BA), Yersinia species, Francisella tularensis (FT), and Category B Brucella species from FTIR spectra. We investigated the classification ability of the Fourier transform infrared (FTIR) spectra of viable pathogenic and non-pathogenic NIAID Category A and B bacteria. The impact of different growth media, growth time and temperature, rolling circle filter of the data, and wavelength range were investigated for their microorganism differentiation. Various 2-D PC plots provided differential degrees of separation with respect to the four viable, bacterial genera including the BA sub-categories of pathogenic spores, vegetative cells, and nonpathogenic vegetative cells. FT spectra were separated from that of the three other genera. The BA pathogenic spore strains 1029, LA1, and Ames were clearly differentiated from the rest of the dataset. Yersinia species were distinctly separated from the remaining dataset and could also be classified by growth media. This work provided evidence that FTIR spectroscopy can separate the four major pathogenic bacterial genera of NIAID Category A and B biological threat agents.

1995-07-01

Despite advances made in recent years in medical first aid, psychiatric intervention, survival training and equipment design, many people still perish quickly during and immediately following a disastrous event. In this study, individuals and groups of survivors of life-threatening events were debriefed and the behavior of those who coped well during such a threat to life were compared with those who did not. The behaviors of those who coped well were distilled into a set of principles for psychological first aid; that is, a series of simple actions for use within a disaster which serves to recover victims to functional behavior as quickly as possible, thus increasing their chance for survival. These principles of psychological first aid have recently been introduced into basic first aid and survival training courses for both military and civilian units.

Effects of donor proliferation in development aid for health on health program performance: A conceptual framework.

PubMed

Pallas, Sarah Wood; Ruger, Jennifer Prah

2017-02-01

Development aid for health increased dramatically during the past two decades, raising concerns about inefficiency and lack of coherence among the growing number of global health donors. However, we lack a framework for how donor proliferation affects health program performance to inform theory-based evaluation of aid effectiveness policies. A review of academic and gray literature was conducted. Data were extracted from the literature sample on study design and evidence for hypothesized effects of donor proliferation on health program performance, which were iteratively grouped into categories and mapped into a new conceptual framework. In the framework, increases in the number of donors are hypothesized to increase inter-donor competition, transaction costs, donor poaching of recipient staff, recipient control over aid, and donor fragmentation, and to decrease donors' sense of accountability for overall development outcomes. There is mixed evidence on whether donor proliferation increases or decreases aid volume. These primary effects in turn affect donor innovation, information hoarding, and aid disbursement volatility, as well as recipient country health budget levels, human resource capacity, and corruption, and the determinants of health program performance. The net effect of donor proliferation on health will vary depending on the magnitude of the framework's competing effects in specific country settings. The conceptual framework provides a foundation for improving design of aid effectiveness practices to mitigate negative effects from donor proliferation while preserving its potential benefits.

The paper compares hydrographic and terrain categories in the geospatial data standards of the US, Taiwan, and Russian Federation where the dominant languages used are from di erent language families. It aims to identify structural and semantic di erences between similar categories across three geospatial data standards. By formalizing the data standard structures and identifying the properties that di erentiate sibling categories in each geospatial data standard using well-known formal relations and quality universals, we develop a common basis on which hydrographic and terrain categories in the three data standards can be compared. The result suggests that all three datamore » standards structure categories with a mixture of relations with di erent meaning even though most of them are well-known relations in top-level ontologies.

Quantum Bianchi identities via DG categories

NASA Astrophysics Data System (ADS)

Beggs, Edwin J.; Majid, Shahn

2018-01-01

We use DG categories to derive analogues of the Bianchi identities for the curvature of a connection in noncommutative differential geometry. We also revisit the Chern-Connes pairing but following the line of Chern's original derivation. We show that a related DG category of extendable bimodule connections is a monoidal tensor category and in the metric compatible case obtain an analogue of a classical antisymmetry of the Riemann tensor. The monoidal structure implies the existence of a cup product on noncommutative sheaf cohomology. Another application shows that the curvature of a line module reduces to a 2-form on the base algebra. We illustrate the theory on the q-sphere, the permutation group S3 and the bicrossproduct quantum spacetime [ r , t ] = λr.

Uncovering contrast categories in categorization with a probabilistic threshold model.

PubMed

Verheyen, Steven; De Deyne, Simon; Dry, Matthew J; Storms, Gert

2011-11-01

A contrast category effect on categorization occurs when the decision to apply a category term to an entity not only involves a comparison between the entity and the target category but is also influenced by a comparison of the entity with 1 or more alternative categories from the same domain as the target. Establishing a contrast category effect on categorization in natural language categories has proven to be laborious, especially when the categories concerned are natural kinds situated at the superordinate level of abstraction. We conducted 3 studies with these categories to look for an influence on categorization of both similarity to the target category and similarity to a contrast category. The results are analyzed with a probabilistic threshold model that assumes categorization decisions arise from the placement of threshold criteria by individual categorizers along a single scale that holds the experimental stimuli. The stimuli's positions along the scale are shown to be influenced by similarity to both target and contrast. These findings suggest that the prevalence of contrast category effects on categorization might have been underestimated. Additional analyses demonstrate how the proposed model can be employed in future studies to systematically investigate the origins of contrast category effects on categorization.

Category-Specific Neural Oscillations Predict Recall Organization During Memory Search

Retrieved-context models of human memory propose that as material is studied, retrieval cues are constructed that allow one to target particular aspects of past experience. We examined the neural predictions of these models by using electrocorticographic/depth recordings and scalp electroencephalography (EEG) to characterize category-specific oscillatory activity, while participants studied and recalled items from distinct, neurally discriminable categories. During study, these category-specific patterns predict whether a studied item will be recalled. In the scalp EEG experiment, category-specific activity during study also predicts whether a given item will be recalled adjacent to other same-category items, consistent with the proposal that a category-specific retrieval cue is used to guide memory search. Retrieved-context models suggest that integrative neural circuitry is involved in the construction and maintenance of the retrieval cue. Consistent with this hypothesis, we observe category-specific patterns that rise in strength as multiple same-category items are studied sequentially, and find that individual differences in this category-specific neural integration during study predict the degree to which a participant will use category information to organize memory search. Finally, we track the deployment of this retrieval cue during memory search: Category-specific patterns are stronger when participants organize their responses according to the category of the studied material.

When does fading enhance perceptual category learning?

PubMed

Pashler, Harold; Mozer, Michael C

2013-07-01

Training that uses exaggerated versions of a stimulus discrimination (fading) has sometimes been found to enhance category learning, mostly in studies involving animals and impaired populations. However, little is known about whether and when fading facilitates learning for typical individuals. This issue was explored in 7 experiments. In Experiments 1 and 2, observers discriminated stimuli based on a single sensory continuum (time duration and line length, respectively). Adaptive fading dramatically improved performance in training (unsurprisingly) but did not enhance learning as assessed in a final test. The same was true for nonadaptive linear fading (Experiment 3). However, when variation in length (predicting category membership) was embedded among other (category-irrelevant) variation, fading dramatically enhanced not only performance in training but also learning as assessed in a final test (Experiments 4 and 5). Fading also helped learners to acquire a color saturation discrimination amid category-irrelevant variation in hue and brightness, although this learning proved transitory after feedback was withdrawn (Experiment 7). Theoretical implications are discussed, and we argue that fading should have practical utility in naturalistic category learning tasks, which involve extremely high dimensional stimuli and many irrelevant dimensions.

Spencer, John P; Hund, Alycia M

2002-03-01

People use geometric cues to form spatial categories. This study investigated whether people also use the spatial distribution of exemplars. Adults pointed to remembered locations on a tabletop. In Experiment 1, a target was placed in each geometric category, and the location of targets was varied. Adults' responses were biased away from a midline category boundary toward geometric prototypes located at the centers of left and right categories. Experiment 2 showed that prototype effects were not influenced by cross-category interactions. In Experiment 3, subsets of targets were positioned at different locations within each category. When prototype effects were removed, there was a bias toward the center of the exemplar distribution, suggesting that common categorization processes operate across spatial and object domains.

Generation and Repair of AID-initiated DNA Lesions in B Lymphocytes

PubMed Central

Chen, Zhangguo; Wang, Jing H.

2014-01-01

Activation-induced deaminase (AID) initiates the secondary antibody diversification process in B lymphocytes. In mammalian B cells, this process includes somatic hypermutation (SHM) and class switch recombination (CSR), both of which require AID. AID induces U:G mismatch lesions in DNA that are subsequently converted into point mutations or DNA double stranded breaks during SHM/CSR. In a physiological context, AID targets immunoglobulin (Ig) loci to mediate SHM/CSR. However, recent studies reveal genome-wide access of AID to numerous non-Ig loci. Thus, AID poses a threat to the genome of B cells if AID-initiated DNA lesions cannot be properly repaired. In this review, we focus on the molecular mechanisms that regulate the specificity of AID targeting and the repair pathways responsible for processing AID-initiated DNA lesions. PMID:24748462

Photographing AIDS: On Capturing a Disease in Pictures of People with AIDS.

PubMed

Engelmann, Lukas

2016-01-01

The photography of people with AIDS has been subject to numerous critiques in the 1980s and has become a controversial way of visualizing the AIDS epidemic. While most of the scholarly work on AIDS photography is based in cultural studies and concerned with popular representations, the clinical value of photographs of people with AIDS usually remains overlooked. This article addresses photographs as a "way of seeing" AIDS that contributed crucially to the making of the disease entity AIDS within the history of medicine. Cultural studies methods are applied to analyze clinical photography in the case of AIDS, thus contributing to the medical history of AIDS through the lens of photography. The article reveals the conflation of disease morphology and patient identity as a characteristic feature of both clinical photography and a now historical nature of AIDS.

School-Based First Aid Training Programs: A Systematic Review.

PubMed

Reveruzzi, Bianca; Buckley, Lisa; Sheehan, Mary

2016-04-01

This review examines the breadth of first aid training delivered to school students and the components that are age appropriate to adolescents. Eligible studies included school-based first aid interventions targeting students aged between 10 and 18 years. Online databases were searched, for peer-reviewed publications available as at August 2014. A total of 20 journal articles were relevant to the review. Research supported programs with longer durations (3 hours or more). Most programs taught resuscitation alone and few included content that was context-specific and relevant to the target group. The training experience of the facilitator did not appear to impact on student outcomes. Incorporating both practical and didactic components was found to be an important factor in delivering material and facilitating the retention of knowledge. Educational resources and facilitator training were found to be common features of effective programs. The review supports first aid in school curriculum and provides details of key components pertinent to design of school-based first aid programs. The findings suggest that first aid training may have benefits wider than the uptake and retention of knowledge and skills. There is a need for future research, particularly randomized controlled trials to aid in identifying best practice approaches. © 2016, American School Health Association.

This study investigated age of acquisition (AoA) effects on processing grammatical category information of Chinese single-character words. In Experiment 1, nouns and verbs that were acquired at different ages were used as materials in a grammatical category decision task. Results showed that the grammatical category information of earlier acquired nouns and verbs was easier to retrieve. In Experiment 2, AoA and predictability from orthography to grammatical category were manipulated in a grammatical category decision task. Results showed larger AoA effects under lower predictability conditions. In Experiment 3, a semantic category decision task was used with the same materials as those in Experiment 2. Different results were found from Experiment 2, suggesting that the grammatical category decision task is not merely the same as the semantic category decision task, but rather involves additional processing of grammatical category information. Therefore the conclusions of Experiments 1 and 2 were strengthened. In summary, it was found for the first time that AoA affects the retrieval of grammatical category information, thus providing new evidence in support of the arbitrary mapping hypothesis.

This study reviewed evidence on the effects of nonresuscitative first aid training on competence and helping behavior in laypersons. We identified randomized and nonrandomized controlled trials and interrupted time series on nonresuscitative first aid training for laypersons by using 12 databases (including MEDLINE, EMBASE, and PsycINFO), hand searching, reference checking, and author communication. Two reviewers independently evaluated selected studies with the Cochrane Effective Practice and Organisation of Care Review Group quality criteria. One reviewer extracted data with a standard form and another checked them. In anticipation of substantial heterogeneity across studies, we elected a descriptive summary of the included studies. We included 4 studies, 3 of which were randomized trials. We excluded 11 studies on quality issues. Two studies revealed that participants trained in first aid demonstrated higher written test scores than controls (poisoning first aid: relative risk 2.11, 95% confidence interval [CI] 1.64 to 2.72; various first aid cases: mean difference 4.75, 95% CI 3.02 to 6.48). Two studies evaluated helping responses during unannounced simulations. First aid training improved the quality of help for a bleeding emergency (relative risk 25.94; 95% CI 3.60 to 186.93), not the rate of helping (relative risk 1.13; 95% CI 0.88 to 1.45). Training in first aid and helping behavior increased the helping rates in a chest pain emergency compared with training in first aid only (relative risk 2.80; 95% CI 1.05 to 7.50) or controls (relative risk 3.81; 95% CI 0.98 to 14.89). Participants trained in first aid only did not help more than controls (relative risk 1.36; 95% CI 0.28 to 6.61). First aid programs that also train participants to overcome inhibitors of emergency helping behavior could lead to better help and higher helping rates.

The purpose of this preliminary study was to assess the HIV/AIDS prevention needs, services, and resources in Liberia, including the readiness of local providers to conduct HIV/AIDS-related prevention programs based on a set of six key dimensions (prevention needs, knowledge, leadership, environment, risky behaviors, and resources). A valid self-administered qualitative-based health survey, based on a community readiness model, was utilized as the primary data collection source. A cross-sectional design that utilized a convenient sample of key informants such as health coordinators, program directors, and health administrator from both public and private HIV/AIDS-based organizations was used. Furthermore, an extensive review of the National Library of Medicine database of published articles from mid-1980 to 2002 was simultaneously conducted to gauge the extent of scientific publications on HIV/AIDS-related prevention services in Liberia. The findings from this study strongly suggest that Liberia is in a stage of vague awareness, as defined by the Tri-Ethnic Center community readiness framework, regarding HIV/AIDS-related activities, including a significant lack of HIV/AIDS-related resources and scientific publications. Accordingly, there is a critical need to acquire adequate resources and build capacity to implement effective HIV/AIDS-related prevention programming services in order to avert the negative public health consequences associated with HIV/AIDS, including the implementation of relevant evaluation and dissemination strategies. Most importantly, this model has the potential to be utilized in other resource-constraint settings, especially in the developing world, to assess prevention-related resources and programmatic readiness. This is the first published study to evaluate Liberia's HIV/AIDS prevention resources and to systematically document the extent and magnitude of the HIV/AIDS crises in the country.

Training Humans to Categorize Monkey Calls: Auditory Feature- and Category-Selective Neural Tuning Changes.

Grouping auditory stimuli into common categories is essential for a variety of auditory tasks, including speech recognition. We trained human participants to categorize auditory stimuli from a large novel set of morphed monkey vocalizations. Using fMRI-rapid adaptation (fMRI-RA) and multi-voxel pattern analysis (MVPA) techniques, we gained evidence that categorization training results in two distinct sets of changes: sharpened tuning to monkey call features (without explicit category representation) in left auditory cortex and category selectivity for different types of calls in lateral prefrontal cortex. In addition, the sharpness of neural selectivity in left auditory cortex, as estimated with both fMRI-RA and MVPA, predicted the steepness of the categorical boundary, whereas categorical judgment correlated with release from adaptation in the left inferior frontal gyrus. These results support the theory that auditory category learning follows a two-stage model analogous to the visual domain, suggesting general principles of perceptual category learning in the human brain.

We show that the trace decategorification, or zeroth Hochschild homology, of the twisted Heisenberg category defined by Cautis and Sussan is isomorphic to a quotient of {W^-}, a subalgebra of W_{1+∞} defined by Kac, Wang, and Yan. Our result is a twisted analogue of that by Cautis, Lauda, Licata, and Sussan relating W_{1+∞} and the trace decategorification of the Heisenberg category.

When is category specific in Alzheimer's disease?

PubMed

Laws, Keith R; Gale, Tim M; Leeson, Verity C; Crawford, John R

2005-08-01

Mixed findings have emerged concerning whether category-specific disorders occur in Alzheimer's disease. Factors that may contribute to these inconsistencies include: ceiling effects/skewed distributions for control data in some studies; differences in the severity of cognitive deficit in patients; and differences in the type of analysis (in particular, if and how controls are used to analyse single case data). We examined picture naming in Alzheimer's patients and matched elderly healthy normal controls in three experiments. These experiments used stimuli that did and did not produce ceiling effects/skewed data in controls. In Experiment 1, we examined for category effects in individual DAT patients using commonly used analyses for single cases (chi2 and z-scores). The different techniques produced quite different outcomes. In Experiment 2a, we used the same techniques on a different group of patients with similar outcomes. Finally, in Experiment 2b, we examined the same patients but (a) used stimuli that did not produce ceiling effects/skewed distributions in healthy controls, and (b) used statistical methods that did not treat the control sample as a population. We found that ceiling effects in controls may markedly inflate the incidence of dissociations in which living things are differentially impaired and seriously underestimate dissociations in the opposite direction. In addition, methods that treat the control sample as a population led to inflation in the overall number of dissociations detected. These findings have implications for the reliability of category effects previously reported both in Alzheimer patients and in other pathologies. In particular, they suggest that the greater proportion of living than nonliving deficits reported in the literature may be an artifact of the methods used.

Categorical perception of color: evidence from secondary category boundary

Despite a plethora of behavioral research exploring the phenomenon of color categorical perception (CP) known as “better discrimination between pair of colors stimuli from different categories and pair of colors stimuli from the same category even when the stimulus differences between the pairs of stimuli are equal”, most of the evidence for the CP of color was derived from Roman or top-to-down script readers and very rarely from right-to-left script readers in primary category. To date, no studies of color CP have been conducted on right-to-left script readers in secondary category boundary to support this theory. Three experiments have been conducted: Experiments 1 and 2 established the Arabic blue–purple secondary category boundary, and Experiment 3 tested the CP of color in the blue–purple category boundary. Sixty participants (30 men and 30 women) took part in this study. All spoke Arabic as their first language, and all were undergraduate or postgraduate students at King Saud University. Their ages ranged from 18–35 years with a mean age of 21.9 years (SD =5.2). The result indicated that for Experiments 1 and 2, it appeared that the Arabic blue–purple category boundary was approximately 10PB and it is in the same location as for English. For Experiment 3, reaction times in the between-categories condition were significantly faster than those in the within-category condition; this suggested that CP of color was shown in the Arabic’s blue–purple secondary category boundary.

Objective Cross-national studies provide inconclusive results as to the effectiveness of foreign health aid. We highlight a novel application of using subnational data to evaluate aid impacts, using Malawi as a case study. Design We employ two rounds of nationally representative household surveys (2004/2005 and 2010/2011) and geo-referenced foreign aid data. We examine the determinants of Malawi's traditional authorities receiving aid according to health, environmental risk, socioeconomic and political factors. We use two approaches to estimate the impact of aid on reducing malaria prevalence and increasing healthcare quality: difference-in-difference models, which include traditional authority and month-of-interview fixed effects and control for individual and household level time-varying factors, and entropy balancing, where models balance on health-related and socioeconomic baseline characteristics. General health aid and four specific health aid sectors are examined. Results Traditional authorities with greater proportions of individuals living in urban areas, more health facilities and greater proportions of those in major ethnic groups were more likely to receive aid. Difference-in-difference models show health infrastructure and parasitic disease control aid reduced malaria prevalence by 1.20 (95% CI −0.36 to 2.76) and 2.20 (95% CI 0.43 to 3.96) percentage points, respectively, and increased the likelihood of individuals reporting healthcare as more than adequate by 12.1 (95% CI 1.51 to 22.68) and 14.0 (95% CI 0.11 to 28.11) percentage points. Entropy balancing shows similar results. Conclusions Aid was targeted to areas with greater existing health infrastructure rather than areas most in need, but still effectively reduced malaria prevalence and enhanced self-reported healthcare quality.

Multimedia category preferences of working engineers

Baukal, Charles E.; Ausburn, Lynna J.

Many have argued for the importance of continuing engineering education (CEE), but relatively few recommendations were found in the literature for how to use multimedia technologies to deliver it most effectively. The study reported here addressed this gap by investigating the multimedia category preferences of working engineers. Four categories of multimedia, with two types in each category, were studied: verbal (text and narration), static graphics (drawing and photograph), dynamic non-interactive graphics (animation and video), and dynamic interactive graphics (simulated virtual reality (VR) and photo-real VR). The results showed that working engineers strongly preferred text over narration and somewhat preferred drawing over photograph, animation over video, and simulated VR over photo-real VR. These results suggest that a variety of multimedia types should be used in the instructional design of CEE content.
