Consumer respondents (203) in the metro-Atlanta statistical area answered a detailed questionnaire pertaining to their attitudes and perceptions of different food groups and food uses. Factor analyses resulted in five food attitude, two food item and three food-use appropriateness factors. The food attitude factors were “Like to Cook”, “Organizational”, “Adventurous”, “Convenience driven” and “Nutrition conscious but casual meal planner”. Food item factors were “Main dish” and “Snack”, Food-use appropriateness factors were “Social”, “Satiety” and “Casual”. A significant correlation between nutrition knowledge and nutrition concern, but not food attitude scores, was found. The “Organizational” factor correlated with the most numbers of variables and “Like to Cook” the least. Results of the respondents in this study indicate that consumers in this sample are leading mobile, dynamic and service oriented lifestyles.  相似文献

Thirty-one caregivers and directors involved in various types of day care for young children were interviewed. Qualitative methods were used to assess their role identity constructs and attitudes toward parents and the child care profession. Caregivers thought of themselves as “mothers,” “grandmothers,” or “teachers.” These social role identities clustered with attitudes about parents and professional role (e.g., “mothers” tended to see parents as neglectful, while “teachers” felt parents failed to reinforce progress made in day care). The authors concluded that conflict over attachment issues contributed to problems between parents and caregivers.  相似文献

An analysis of the contributions of “omics technologies” to human health and clinical care needs to address the relationships between internal issues (e.g., methodological shortcomings in “omics” research and clinical biology) and external influences. Among the latter, monetization of intellectual property (IP) appears to be a powerful force favoring methodological limitations and an excessive reductionism and fragmentation of biological knowledge. Following economic successes in other industries (semiconductors, software, and “dot-coms”), monetization of IP tries to market small fragments of big research “puzzles”; the strategy seems partly responsible for the biotech industry having underperformed methodological, clinical, and economic expectations. Hence, internal, purely scientific reasons can hardly explain failures in the application of long-proven principles of clinical epidemiology to the discovery and validation of diagnostic and prognostic tests. Nevertheless, this paper also sketches methodological proposals that may help integrate microbiological, clinical, and environmental evidence. Clinical and epidemiological reasoning, knowledge, and methods need to be applied on a much wider scale than until now by “omics” studies that aim at making inferences relevant for human beings. Rather than adopting the values and norms of “science business,” “omics research” could apply a diversity of clinicoepidemiological models favoring integrative research.  相似文献

Diana Baumrind's typology of parenting is based on a two-factor model of “control” and “warmth”. Her recommended discipline style, labeled “authoritative parenting”, was constructed by taking high scores on these two factors. A problem with authoritative parenting is that it does not allow for flexible and differentiated responses to discipline situations. It is argued that a simpler, and more adequate, approach would be to switch to a model of discipline with a third factor, labeled “tolerance”. Parents of the most socially competent children are adept at knowing when they have a problem and when they do not. An example of the latter would be when a child expresses negative affect while complying fully with a request. Baumrind's notion of authoritative parenting was a useful “dialectic”, demonstrating that control and warmth are independent and equally necessary behaviors, but it did not go far enough. Baumrind's category of harmonious parenting (high warmth, moderate control, high tolerance), which she sees as an anomaly, should be substituted for authoritative parenting as the preferred discipline pattern.  相似文献

The standard technique for Norplant implants removal was compared with a new technique called the “U” technique, which employs the use of a modified no-scalpel vas deferens holding forceps to grasp and remove the capsules. Seventy-six women requesting Norplant implants removal were randomly assigned to Group 1 (standard removal technique) or Group 2 (“U” removal technique). Variables measured included: (a) time required for complete removal, (b) number of capsules not broken or damaged during removal, and (c) number of incisions required for removal of all six capsules. In clients with visible or palpable capsules, the standard removal technique required significantly more time to remove all six capsules, on average, than the “U” technique (19 versus 7 minutes, p < 0.001); also more capsules were damaged during removal (5.6 undamaged versus 6.0,p < 0.01). In addition, with the standard technique, five clients required two incisions for removal of all six capsules while none of the clients required more than one incision with the “U” technique. Our conclusion is that the “U” technique is a quicker and easier method of removing Norplant capsules than the standard technique.  相似文献

Consumers often decide to purchase certain items as a result of prompt emotional responses evoked by the products; therefore, it is important to investigate the emotional responses stimulated by food samples, as well as the sensory attributes of the products. The aim of this study was to examine influences of sensory attribute and emotional response on olfactory hedonic ratings of dairy products. Additionally, we compared this effect between women and men subjects. Sensory attributes of six natural odors produced by commercial dairy products were evaluated by 9 trained panelists. In addition, 100 untrained panelists (50 women and 50 men) rated the emotional response stimulated by the 6 odors using 25 paired semantic differential scales and the hedonicity using a 9 cm line scale, respectively. Untrained panelists more liked “sweet aromatics,” “sour aromatics,” “fermented aromatics,” and “rich aromatics” over the other sensory attributes of dairy products. The olfactory hedonic ratings were increased when the odor was more characterized as “fragrant,” “attractive,” “comfortable,” “familiar,” “faint,” “natural,” or “modern.” Specific sensory attributes were found to be related to specific adjective pairs representing the emotional response. Moreover, the ratings of adjective pairs representing emotional response of odors and their influences on hedonic ratings differed significantly between sexes. In conclusion, our findings suggest that the emotional responses as well as the sensory attributes affect the hedonic ratings of odors in dairy products.  相似文献

Estimating human immunodeficiency virus (HIV) prevalence from sentinel seroprevalence studies is difficult. We characterize these studies and show that most are investigations of incompletely defined (hypothetical) cohorts and are usually based on nonprobability samples. Prevalence in HIV sentinel serosurveys is also time-averaged and vulnerable to several time-dependent sources of bias (e.g., migration, deaths, and changes in incidence). Assumptions must be made that these time-dependent biases did not meaningfully affect the data, and this can be helped by reducing the period of investigation. Furthermore, we show that “reliability” can not be adequately measured by standard error, that “internal validity” is vulnerable to self-selection bias and laboratory problems, and that “generalizability” is limited. We propose that what is needed is a procedure (like formal metaanalysis methods) incorporating information from several separate HIV sentinel seroprevalence studies, in a manner that is reproducible and can take into consideration the differences between studies.  相似文献

In an attempt to better understand why children who have been sexually assaulted commonly fail to reveal their victimization to parents or other adults, a study was undertaken in which the “engagement strategies” of 41 perpetrators were examined, exploring common rationalizations, threats, etc. aimed at insuring continued silence on the part of the victim. The “appeal” for silence offered by the perpetrator to the child was analyzed according to Kohlberg's stages of moral development.

Results indicate that perpetrators appear to alter their engagement strategies to coincide with the developmental level of the child, thus further insuring silence by appealing to criteria for assessing “appropriate” or “inappropriate” behaviors (eg. sexual contact) which are developmentally consistent with the child's level of cognition and moral reasoning.  相似文献

The term “clinimetrics” was introduced by Feinstein to describe an approach to scale development that ostensibly is different from the more traditional “psychometrics.” I argue that, for a number of reasons, it is time for this term to retire from the scene. I show that the clinimetric approach is neither new nor unique, but is rather a subset of psychometrics. Further, because the majority of new developments in scale construction (e.g., new variations of the intraclass correlation, item response theory, structural equation modeling, and cognitive theories) are reported in the psychometric literature, use of the term “clinimetric,” especially among people not exposed to traditional test theory, cuts them off from a rich source of information.  相似文献

Toxicants and organic matter in river water have contrasting impacts on macrofauna. Through manipulations of both factors, their interactive effects on organisms were evaluated. This way, an attempt was made to clarify the presence or absence of pollution-“tolerant” and -“sensitive” species in rivers affected by mixed sources of pollution. Under controlled conditions, larval growth of the “tolerant” midge Chironomus riparius was measured in different types of river water containing varying levels of particles (obtained by selective filtration) and toxicants (either complex mixtures or metals). Exposure of first-instar larvae to water from the polluted rivers Meuse and Dommel revealed that growth was less inhibited by toxicant levels in river water than expected based on laboratory toxicity tests. Factors present in polluted river water stimulated growth of midges to such an extent that inhibiting effects of high toxicant concentrations were neutralized, and at low toxicant levels, were overcompensated for. It was found that particulate matter has great potential to reduce inhibiting effects of toxicants on C. riparius, not (only) by reducing the bioavailability of toxicants, but by serving as a supplementary, superior food source. The success of the “pollution-tolerant” midge was not explained by tolerance of this species to toxicants, but by its ability to take advantage of coinciding organic enrichment. It is hypothesized that the extent to which beneficial effects of organic compounds on organisms occur is species specific.  相似文献

This paper reports findings from fieldwork in situations that brought young children and child welfare practitioners together with the aim of diagnosing and treating children's communication difficulties. The findings suggest that communication difficulties tend to be treated as a property of the individual child rather than as an emergent, contextual property of interaction. The attention will be steered from clinical definitions of “impairment” and “disability” to dynamics of social interaction, where understandings of “good” and “normal” communication play a central role. The findings have implications for current recommendations for good practice, which derive from needs-led, rights-led and skills-led approaches.  相似文献

Among the most prominent health or medical stories covered in 1994 by the Australian news media was that concerning an HIV positive hospital obstetrician and the attempt by the New South Wales Health Department to trace and test 149 women on whom he had operated. All press and television coverage of the issue was reviewed. The surface news narrative of the search for missing, “innocent” mothers potentially infected with a deadly and infectious illness is shown to serve as a “hard news” pretext enabling a wider major discourse to operate about a health system accused as being captive to gay and civil libertarian politics, allowing “guilty” doctors at high risk of HIV to endanger “innocent” patients. Expert consensus held that the women were at “infinitesimal risk” of acquiring HIV. However, media accounts of the investigation all but belied this, illustrating that the news media's framing of risk has more to do with its reproduction of moral outrage components than with “scientific” notions of calculable risk.  相似文献

Health and housing conditions in public sector housing estates   总被引:2,自引:0,他引:2  
This article reports some of the findings of a study of health and housing conditions ina sample of households from eight different types of council housing areas in Gateshead.Controlling for age, there were found to be marked and consistent differences in self-reported health between individuals from different areas. For all age groups up to 65 years old, those living in “bad” housing areas reported poorer health, more long-standing illness, more recent illness and more symptoms of respiratory disease and depression. The clearest associations between poor health and bad housing emerged for the generally fittest age-groups (the under 25 years). For the people over 65 years the position was reversed, with those in “good” housing areas reporting poorer health, with the exception of recent illness. This is argued to be the result of local authority lettings policy, which gives priority to re-housing the less-fit elderly.Those in “bad” housing areas were also more likely to report housing defects which affected their health and to feel that their health could be improved by a change in their housing.The study found that “bad” council housing areas did not necessarily conform to thestereotype of non-traditional construction, or high-rise flats. Some consisted of traditionally built houses, while there was a sizeable representation among the “good” housing of system-built high-rise flats. The “bad” housing areas were marked off more by their location, their poor environment and the low quality of their construction.  相似文献

Six tests for detection of antibodies against the non-structural proteins of foot-and-mouth disease virus (FMDV) were compared at an international workshop in Brescia, Italy in 2004 on the basis of dichotomous test results. However, as results from all of these assays were also available on a continuous scale, validation was extended by calculating and subsequently analysing the receiver-operator characteristic (ROC) curves and likelihood ratios (LR) for each test method. For the purposes of these analyses, test results for a total of 1337 sera were selected from the Brescia workshop dataset, 237 sera that had been obtained from cattle exposed to FMDV and 1100 sera obtained from cattle that were not exposed to the virus; sera from “exposed” cattle were considered to be “true positives” and sera from “non-exposed” cattle were considered to be “true negatives”. Analysis of ROC curves showed that at specificities of both 99 and 99.5%, the IZS-Brescia and the Ceditest ELISA had significantly better detection rates in exposed cattle than the other ELISAs. The ROC analysis confirms the previous finding that the IZS-Brescia and the Ceditest ELISAs have both better detection rates in exposed cattle combined with a high specificity. The analysis of likelihood ratios provides information that may be very useful in the interpretation of test results, and a working example is presented to show how these likelihood ratios might be used in an objective approach to deciding the true infection status of surveyed populations.  相似文献

This paper described a research project, Play and Learning, to investigate the mental processes that underlie children's activities in “free play” and “structured learning” situations in preschool. Interviews of children about “what they did” were used to investigate children's own views of play and learning.  相似文献

Observational assessment is an important component of a comprehensive evaluation of children's procedural pain. An understanding of children's behavior during painful procedures can inform the structure of these measures and is important in the development of effective interventions. This study used principle components analyses to evaluate the structure of children's behavior during routine immunizations. Videotapes of 159 children undergoing routine immunizations were coded using the Child-Adult Medical Procedure Interaction Scale (Blount et al., 1989). Results indicated a 4-component solution was the most appropriate categorization and accounted for 61.2% of the variance in children's behavior. The first 3 components represented “verbal fear” (seeking emotional support, verbal fear, information seeking), “vocal pain” (cry, verbal resistance, verbal pain), and “escape behavior” (need for restraint, flail). The final component, “other verbal behavior” consisted of nonprocedural talk and negative verbal emotion. Taken together, the preliminary results of the correlational analyses and the subsequent principal components analyses support the assertion that children's distress is a multidimensional experience and should be evaluated as such. Attention to multiple dimensions of distress is important in the evaluation of interventions as they may differentially target these dimensions.  相似文献

A tenet of attachment theory (Bowlby, 1969; Ainsworth, Blehar, Waters and Wall, 1978) is that attachments develop within the context of, and are thus influenced by, early interactions. “Sensitivity” has been asserted by many researchers to be the key feature of interactions promoting “secure” attachment relationships. Attachment theorists assume that attachment quality is based on the nature of a caregiver's responses to an infant's signals for proximity and contact. Although there appears to be broad agreement in the literature on the importance of maternal sensitivity in affecting attachment relationships, writers differ in their definition of “sensitivity” and the relative emphasis placed on particular aspects of parental behaviour in explaining its effect on attachment.

This paper reviews the literature addressing the construct of “sensitivity”. The problem of defining this construct will be highlighted by summarising relevant literature and identifying the range of behaviours typically used as indicators of sensitivity. Relations between these definitions will be highlighted to reveal the main threads of continuity. Issues related to the concept of sensitivity, arising from reviewing this literature, will be discussed.  相似文献

Cultural groups vary considerably in their expectations of work around the house by children, and these variations provide a window for viewing ideas about the nature of children and of family life. This paper provides (a) a summary of differences found between two cultural groups in Australia (Australian-born and Lebanese-born), (b) a review of differences found within historical studies and within other cross-cultural comparisons, and (c) a report on approaches and concepts to children's work within a further Australian-born group (a report that considers views about money for work as well as some general underlying principles about work that can legitimately be asked of others and work that cannot). The important differences among cultures, it is argued, have to do not only with the expectations of work, but also with the way parents mark some jobs as different from others (e.g. “regular” vs. “extra”, boys' work or girls' work, can be pased on vs. cannot be), and with the way they use, as a sign of whether a child is acquiring the desired concepts of family life, the child's understanding of phrases such as “your job” and the child's recognition of the mother's work.  相似文献

Traditional medicine, its preparations and practices, plays a major role in the health care of the community of Nigeria. In many cases the native doctor (“Babalawo”) and the local herbalist (“Eleweomo”) are the only practitioners available for the treatment of illness. Even in the towns where allopathic medicine is available the limited facilities it offers make many patients rely on traditional methods. Little is known of the pharmacological action of these traditional remedies which the native doctor prescribes. Our own studies have concentrated on the metal content of such materials. Here we report on the material known as “tiro” which is used for the treatment of eye infections and disease as well as an “eye cleaner” and cosmetic. On analysis we found that all samples of tiro measured contained lead ranging from 12·8 to 81·1% (w/w), with a mean concentration over all samples determined of 50·1% (w/w). In addition, it was also found that tiro is used by some members of the Nigerian community in Britain and is brought in in decorative containers as a gift. The extent of use in this country still remains to be determined, however. The use of lead-containing preparations* in traditional practices presents a significant health hazard to a substantial section of the world's population. We suggest urgent steps are required to encourage governments to establish education programmes to eliminate this avoidable source of morbidity among their populations.  相似文献
