Rethinking the paradigm for child protection.

Mounting pressures on the nation's system for helping children who are abused and neglected have prompted new efforts to reform the child protective services (CPS) system to better protect children's safety. As this article explains, current reform efforts are focusing on the "front end" of the system, in which reports of abuse and neglect are screened and investigated, and caseworkers recommend whether and when to close a case, provide in-home services, or remove a child from a home. This article discusses the problems of the CPS system that are currently receiving attention, and it closely examines one proposal for reform--the community-based partnership for child protection. This approach emphasizes targeting investigations by CPS toward only high-risk families, building collaborative community networks that can serve lower-risk families, and providing a differentiated response to both high- and low-risk families that is tailored to each family's situation. Early experiences implementing these ideas in Missouri, Florida, and Iowa illustrate the promise and challenges of reform.

A signal-flow-graph approach to on-line gradient calculation.

A large class of nonlinear dynamic adaptive systems such as dynamic recurrent neural networks can be effectively represented by signal flow graphs (SFGs). By this method, complex systems are described as a general connection of many simple components, each of them implementing a simple one-input, one-output transformation, as in an electrical circuit. Even if graph representations are popular in the neural network community, they are often used for qualitative description rather than for rigorous representation and computational purposes. In this article, a method for both on-line and batch-backward gradient computation of a system output or cost function with respect to system parameters is derived by the SFG representation theory and its known properties. The system can be any causal, in general nonlinear and time-variant, dynamic system represented by an SFG, in particular any feedforward, time-delay, or recurrent neural network. In this work, we use discrete-time notation, but the same theory holds for the continuous-time case. The gradient is obtained in a straightforward way by the analysis of two SFGs, the original one and its adjoint (obtained from the first by simple transformations), without the complex chain rule expansions of derivatives usually employed. This method can be used for sensitivity analysis and for learning both off-line and on-line. On-line learning is particularly important since it is required by many real applications, such as digital signal processing, system identification and control, channel equalization, and predistortion.

The health-promoting school: what role for nursing?

AIM: To review the existing literature on health-promoting schools and put forward recommendations for continuing progress. BACKGROUND: The World Health Organisation's Ottawa Charter for Health Promotion in 1986 sought to create a framework for health promotion action that conveyed the notion of capacity building as it related to specific settings. It provided the catalyst from which the health-promoting school movement emerged, against the backdrop of health professionals adapting to the changing needs and demands of clients and the evolving social context of the communities in which they live. Since then, the international health-promoting school movement has been one of the most successful of the settings-based projects and has expanded considerably over recent years. METHOD: An extensive review of available health-promoting school-related literature provides the basis for critical discussion and recommendations. FINDINGS: Traditionally, the school nursing movement has provided the backbone of nursing-related health promotion activity in the school setting. The literature, however, is generally critical of its contribution over the years - especially as its role is mainly confined to a 'conventional' health education function and has little to do with health-promoting school projects. There are more and more calls now for the school nursing service to either re-evaluate its function and processes or be devolved back into a broader primary health care practitioner role. CONCLUSION: Nurses should view the health-promoting school movement as another opportunity to embrace evolving broad-based health promotion concepts truly, as a means to forge and own their own health agenda and also as a means to move beyond a traditional reliance on a limited health education role. Schools also need to adapt and expand their efforts to focus on health promotion activities, in collaboration with the ever-widening community networks of health and social agencies. This requires the commitment of all healthcare professional groups. Nurses who practice in all settings, and not just school nurses, should be aiming to initiate and promote radical health promotion reform as set out in the health-promoting school movement. RELEVANCE TO CLINICAL PRACTICE: If health professionals wish to be at the forefront of current health-promoting school strategies they must embrace the radical health promotion reforms that are emerging from the current literature and put forward in this article. Building such group capacity, through developing social interaction, cohesion, participation and political action can only benefit the community at large and further emphasize the health promotion role of nursing. The health-promoting school movement is truly an international concept and, as such, deserves a concerted nursing representation and resourcing well beyond its current commitment.

Identification of gaps in the diagnosis and treatment of childhood asthma using a community-based participatory research approach.

The goal of this investigation was to use a community-based participatory research approach to develop, pilot test, and administer an asthma screening questionnaire to identify children with asthma and asthma symptoms in a community setting. This study was conducted as the recruitment effort for Community Action Against Asthma, a randomized trial of a household intervention to reduce exposure to environmental triggers of asthma and was not designed as a classic prevalence study. An asthma screening questionnaire was mailed and/or hand delivered to parents of 9,627 children, aged 5 to 11 years, in two geographic areas of Detroit, Michigan, with predominantly African American and Hispanic populations. Additional questionnaires were distributed via community networking. Measurements included parent report of their child's frequency of respiratory symptoms, presence of physician diagnosis of asthma, and frequency of doctor-prescribed asthma medication usage. Among the 3,067 completed questionnaires, 1,570 (51.2% of returned surveys, 16.3% of eligible population) were consistent with asthma of any severity and 398 (12.9% of returned surveys, 4.1% of eligible population) met criteria for moderate-to-severe asthma. Among those meeting criteria for moderate-to-severe asthma, over 30% had not been diagnosed by a physician, over one half were not taking daily asthma medication, and one quarter had not taken any physician-prescribed asthma medication in the past year. Screening surveys conducted within the context of a community-based participatory research partnership can identify large numbers of children with undiagnosed and/or undertreated moderate-to-severe asthma. These children are likely to benefit from interventions to reduce morbidity and improve quality of life.

Managed care can be better care for all citizens: a primary care perspective.

The CPN seeks to enhance the care of patients by judicious expenditure of health care dollars, currently for the Unit "Community" Network, but ultimately also for other insurers who would enter risk-sharing relationships with the CPN. Improvements in health care delivery will be made in enhanced access to primary care, including telephone access to nurse triage; in collaboration and communication between the selected consultant and the referring primary care giver, including an electronic network allowing for selected information sharing; and in renewing medicine's collective commitment to care provided as close to home as possible, or in the home if this is the highest quality. The care of the uninsured remains a challenge and a normal obligation from which the CPN does not shrink. The economic realities of primary care delivery must be improved, with additional resources allocated being substantially rededicated to patient care. The patient's control of the selection of the site of health care and the absence of incentives to their primary care provider for a referral pattern different than the patient's choice will remain important to the CPN. The CPN hopes to provide the diplomacy between third party payers to enhance collaboration and minimize competition in the delivery of care in communities.

Health promoting hospitals: the role and function of nursing.

BACKGROUND: In 1986, the World Health Organisation's (WHO) Ottawa Charter for Health Promotion sought to create a framework that conveyed the notion of capacity building, related to specific settings, and a structured process for health promotion action. It provided the platform from which the health promoting hospital movement was later launched. Nearly two decades on, the health promoting hospital (HPH) movement has grown considerably and continues to expand, against the backdrop of having to adapt to the changing needs and demands of clients and the evolving social context of their communities. Many nurses, it is argued here, are often unaware of health promoting hospitals concepts or, when they are, do little to contribute to them. METHOD: A critical review of the available health promoting hospital and related literature has been conducted for discussion. FINDINGS: The literature revealed that hospitals are being urged to reject practices based purely on health-limiting and limited biomedical frameworks, in favour of moving towards models based on health promoting hospitals and public health-orientated hospitals. This requires radical reform that focuses on the social and health policy context of organizations, the socio-political empowerment of its employers and clients, and the personal/collective positive health and welfare of its employers and clients. Many health service agencies are beginning to emphasize population health within communities as part of a concerted move away from an original primary focus on acute inpatient hospital-based service provision. CONCLUSION: Hospitals need to adapt and expand their efforts to focus on health promotion activities, in collaboration with the ever-widening community networks of health and social agencies. This requires the commitment of all health care professional groups. Nurses who practice in the hospital setting should be aiming to initiate and promote radical health promotion reform as set out in the health promoting hospital movement. This paper argues that nursing per se could be making much larger inroads and efforts to affect and implement wide-ranging health promotion activities in hospital organizations. Nurses should view the HPH movement as another opportunity truly to embrace evolving broad-based health promotion concepts, as a means to forge and own their own health agenda, and also as a means to move beyond the traditional reliance of a limited health education role. RELEVANCE TO CLINICAL PRACTICE: Hospitals and their employees must be seen to advocate, support and implement wide-reaching social and community-based reform, as part of a necessary commitment to 'seamless' health care provision. The health promoting hospital movement represents a collective vehicle for enabling such activities. If nurses wish to be at the forefront of current health service strategies they must be seen to embrace the radical health promotion reforms that are emerging from the current literature and put forward in this article.

The practice of community psychiatric nursing and mental health social work in Salford. Some implications for community care.

The context and content of work undertaken with individual clients by community psychiatric nurses (CPNs) and mental health social workers (MHSWs) in Salford were found to be significantly different. Although there were some areas of overlap, the ways in which the two professions worked were quite distinct. MHSWs discussed a wide range of topics and were as concerned with clients' interactions with family and community networks as they were with symptoms. Their interviews with schizophrenic clients followed a similar pattern to those with other groups, and they worked closely with psychiatrists and other mental health staff. CPNs, on the other hand, focused mainly on psychiatric symptoms, treatment arrangements, and medications, and spent significantly less time with individual psychotic clients than they did with patients suffering from neuroses. They were as likely to be in contact with general practitioners as they were with psychiatrists, and had fewer contacts with other mental health staff than the MHSWs. There was evidence that the long-term care of chronic psychiatric patients living outside hospital required more co-ordinated long-term multidisciplinary input.

Where health and welfare meet: social deprivation among patients in the emergency department.

CONTEXT: As a safety net provider for many disadvantaged Americans, the emergency department (ED) may be an efficient site not only for providing acute medical care, but also for addressing serious social needs. OBJECTIVE: To characterize the social needs of ED patients, and to evaluate whether the most disadvantaged patients have connections with the health and welfare system outside the ED. DESIGN: Cross-sectional survey conducted over 24 hours in the fall of 1997. SETTING: Three EDs: an urban public teaching hospital, a suburban university hospital, and a semirural community hospital. PARTICIPANTS: Consecutive patients presenting for care, including those transported by ambulance. The survey response rate was 91% (N = 300; urban = 115, suburban = 102, rural = 83). MAIN OUTCOME MEASURE: Index of socioeconomic deprivation described by the US Census Bureau (based on food, housing, and utilities). RESULTS: Of all ED patients, 31% reported one or more serious social deprivations. For example, 13% of urban patients reported not having enough food to eat, and 9% of rural patients reported disconnection of their gas or electricity (US population averages both less than 3%). While 40% of all patients had no consistent health care outside the ED (< or = 1 visit/year), those with higher levels of social deprivation had the least contact with the health care system outside the ED (P < .01). Although those with higher levels of deprivation were more likely to receive public assistance, still almost one-quarter of patients with high-level social deprivation were not receiving public aid. CONCLUSION: Many ED patients suffer from fundamental social deprivations that threaten basic health. The most disadvantaged of these patients frequently lack contact with other medical care sites or public assistance networks. Community efforts to address serious social deprivation should include partnerships with the local ED.

The development of SisterTalk: a cable TV-delivered weight control program for black women.

Overweight and obesity have reached epidemic proportions in the United States, with black women disproportionately affected. SisterTalk is a weight control program designed specifically for delivery to black women via cable TV. The theoretical and conceptual frameworks and formative research that guided the development and cultural tailoring of SisterTalk are described. Social Action Theory was applied in the development of SisterTalk along with a detailed behavioral analysis of the way that black women view weight and weight loss within the context of their cultural and social realities. The entire intervention development process was framed using this information, rather than by changing only superficial aspects of program delivery. Community networking and both qualitative and quantitative interview techniques from the fields of social marketing and cultural anthropology were used to involve black women from Boston in the design and implementation of a program that would be practical, appealing, and culturally sensitive. Also discussed are strategies for evaluating the program, and lessons learned that might have broader applicability are highlighted. The development of the SisterTalk program could provide a useful starting point for development of successful weight control programs for black women in other parts of the United States as well as for other ethnic and racial groups.

Evaluating alternative treatments for homeless substance-abusing men: outcomes and predictors of success.

The present study was designed to explore the relative efficacy of three types of service delivery intervention models for homeless men with alcohol and/or drug problems: integrated comprehensive residential services provided at one site (Group 1); on-site shelter-based intensive case management with referrals to a community network of services (Group 2); and usual care shelter services with case management (Group 3). In addition to assessing the relative efficacy of these approaches in terms of drug and alcohol use, residential stability, economic and employment status, the project also sought to examine what personal factors best predicted successful outcomes for clients. Clients were assessed at baseline and approximately six months following discharge. All three treatment groups improved significantly over time in terms of reduced alcohol and cocaine use, increased employment, and increased stable housing, but no differential improvement was found among groups. Successful outcomes were predicted by lower recent and lifetime substance use, fewer prior treatment episodes, more stable housing at baseline, fewer incarcerations, and less social isolation.

Nonlinear autoassociation is not equivalent to PCA.

A common misperception within the neural network community is that even with nonlinearities in their hidden layer, autoassociators trained with backpropagation are equivalent to linear methods such as principal component analysis (PCA). Our purpose is to demonstrate that nonlinear autoassociators actually behave differently from linear methods and that they can outperform these methods when used for latent extraction, projection, and classification. While linear autoassociators emulate PCA, and thus exhibit a flat or unimodal reconstruction error surface, autoassociators with nonlinearities in their hidden layer learn domains by building error reconstruction surfaces that, depending on the task, contain multiple local valleys. This interpolation bias allows nonlinear autoassociators to represent appropriate classifications of nonlinear multimodal domains, in contrast to linear autoassociators, which are inappropriate for such tasks. In fact, autoassociators with hidden unit nonlinearities can be shown to perform nonlinear classification and nonlinear recognition.

[Reform of psychiatry in Spain].

Since the 1980's psychiatric care in Spain changed considerably (Reforma psiquiátrica española). In the course of this reform, many positive results were achieved. An extensive community network of mental health centres was build up which resulted in the majority of psychiatric patients being integrated in the Spanish general health care system and making a better organized mental health care structure possible. New legislation also improved the care and civil rights of patients. An analysis of the experiences of the Spanish psychiatric reform shows that the tendency to retain the old mental hospitals, alongside the other institutions still exists. The process of deinstitutionalization and the original aims of the psychiatric reform cannot only be satisfied by the closure of large psychiatric hospitals as during the reform new aspects and problems as well the great complexity of the task have become apparent. This article together with the details of the Spanish sources gives the German public a good overview of the developments in Spanish psychiatry.

The general inefficiency of batch training for gradient descent learning.

Gradient descent training of neural networks can be done in either a batch or on-line manner. A widely held myth in the neural network community is that batch training is as fast or faster and/or more 'correct' than on-line training because it supposedly uses a better approximation of the true gradient for its weight updates. This paper explains why batch training is almost always slower than on-line training-often orders of magnitude slower-especially on large training sets. The main reason is due to the ability of on-line training to follow curves in the error surface throughout each epoch, which allows it to safely use a larger learning rate and thus converge with less iterations through the training data. Empirical results on a large (20,000-instance) speech recognition task and on 26 other learning tasks demonstrate that convergence can be reached significantly faster using on-line training than batch training, with no apparent difference in accuracy.

The challenge of PACS in a small hospital.

Memorial Hospital is located in-North Conway, New Hampshire. Year round, the 35-bed hospital serves mainly tourists and retirees to the area. The imaging department wanted to integrate its services within an existing community network, meet the needs of a transient population and resolve staff utilization and storage problems. Conversion from film to digital in the radiology department took advantage of digital x-ray and PACS. Since the hospital was already using digital technology for CT, MR, ultrasound and fluoroscopy, it made sense to include plain film imaging in the digitization process Memorial Hospital faced a number of challenges. Those in decision-making positions lacked a general knowledge about PACS, and, in particular, about PACS in similarly sized facilities. The hospital also lacked experience working with vendors. A timeline was critical as Memorial Hospital prepared for winter, its busiest season. The facility decided on a phased-in project with no immediate HIS/RIS interface, and computerized radiography with hard-copy films was implemented immediately. The facility has made the transition from a conventional imaging department to a PACS environment. It attributes its success to the way it involved those who would be affected by any future changes in the planning and decision-making processes. Memorial Hospital expects to expand its services and streamline its archival capabilities in the near future.

The psychological and medical sequelae of war in Central American refugee mothers and children.

OBJECTIVE: To investigate the physical and mainly psychological sequelae of exposure to war in Central American children and their mothers who immigrated to the United States on average 4 years before the study began. DESIGN: Interview study. PARTICIPANTS: Twenty-two immigrant Central American women caretakers and 1 of their children aged 5 to 13 years. MAIN OUTCOME MEASURES: Standardized and new measures were administered to assess children's physical and mental health symptoms and exposure to political violence. RESULTS: Eighteen of the 22 children had chronic health problems. Fifteen children and all of the adults had observed traumatic events, including bombings and homicides. Thirteen of the children showed mental health symptom profiles above established norms, although only 2 met the criteria for posttraumatic stress disorder according to their own reports. Many of the caretakers were unaware of their child's psychological distress. Four of the mothers exhibited posttraumatic stress disorder, and their symptoms predicted their child's mental health. CONCLUSIONS: Pediatricians are sometimes the first and only contacts these families have with health care providers. Caretakers' reports of children's mental health are often incomplete. It is therefore important for physicians to probe for "hidden" symptoms in refugee children. These family members may need referrals to social and psychological services, and pediatricians can open the gates to existing community networks of support. Because we found that maternal mental health influences the child's, the child's interests are well served when pediatricians also encourage the mother to contact services for herself if she confides that she is experiencing some of the severe psychological sequelae reported by the women in this study.

Willingness to pay for rural health insurance through community participation in India.

The main objective of this article is to examine the willingness to pay for a viable rural health insurance scheme through community participation in India, and the policy concerns it engenders. The willingness to pay for a rural health insurance scheme through community participation is estimated through a contingent valuation approach (logit model), by using the rural household survey on health from Karnataka State in India. The results show that insurance/saving schemes are popular in rural areas. In fact, people have relatively good knowledge of insurance schemes (especially life insurance) rather than saving schemes. Most of the people stated they are willing to join and pay for the proposed rural health insurance scheme. However, the probability of willingness to join was found to be greater than the probability of willingness to pay. Indeed, socio-economic factors and physical accessibility to quality health services appeared to be significant determinants of willingness to join and pay for such a scheme. The main justification for the willingness to pay for a proposed rural health insurance scheme are attributed from household survey results: (a) the existing government health care provider's services is not quality oriented; (b) is not easily accessible; and, (c) is not cost effective. The discussion suggests that policy makers in India should take serious note of the growing influence of the private sector and people's willingness to pay for organizing a rural health insurance scheme to provide quality and efficient health care in India. Policy interventions in health should not ignore private sector existence and people's willingness to pay for such a scheme and these two factors should be explicitly involved in the health management process. It is also argued that regulatory and supportive policy interventions are inevitable to promote this sector's viable and appropriate development in organizing a health insurance scheme.
