International service learning programs: ethical issues and recommendations

Inequities in global health are increasingly of interest to health care providers in developed countries. In response, many academic healthcare programs have begun to offer international service learning programs. Participants in these programs are motivated by ethical principles, but this type of work presents significant ethical challenges, and no formalized ethical guidelines for these activities exist. In this paper the ethical issues presented by international service learning programs are described and recommendations are made for how academic healthcare programs can carry out international service learning programs in a way that minimizes ethical conflicts and maximizes benefits for all stakeholders. Issues related to project sustainability and community involvement are emphasized.     

Anthropology and television: Ethnographic‐ethnological topics on German television

The following paper gives an overview of the various programs with ethnographic‐ethnological content shown on Channels I and III of ARD, a public broadcasting company in Germany, from 1965 until 1989. Research focused on ethnographic‐ethnological content of documentary films in general and thus also included television programs whose theme as a whole differed from this topic. Based on a review of the data of a total of 280 programs, 4 categories of program are classified: 1. Eth nographic television programs; 2. Television programs with ethnographic elements; 3. Television programs with an ethnological topic; and 4. Border‐line cases, i.e. programs which are remarkable from an anthropological point of view but which cannot directly be classed with one of the categories above. Most of the programs with ethnographic‐ethnological content are broadcast on Channel III which addresses target groups with specific interests. This aim was more visible during the first years of the existence of Channel III at the end of the Sixties and during the Seventies than it is nowadays. The change is reflected in the quality of programs containing ethnographic‐ethnological topics over the years. In general a shift can be noted from programs with an outstanding visual quality (although they always have been rare) to programs which derive from the journalistic tradition of television and put a major stress on commentary. Through the years a change in the topics presented becomes apparent. The Seventies were the period when the majority of programs shown were on tribal societies. From the end of that decade until the mid‐Eighties there was an increase in the number of programs covering other non‐tribal ethnic groups. Moreover, topics such as ethnic minorities, even in Europe, urban groups or the various daily life‐styles of people within a whole state or country, emerged, and more emphasis was given to social and political aspects. The research reveals that television as a medium is open to different programs with ethnographic‐ethnological content. Apart from the quality of the programs offered, the abundance and variety of programs available reflects a wide interest in foreign nations and cultures. Anthropologists should acknowledge that fact in order to make ethnological knowledge available to a wider audience.     

EQA from an Australian perspective

Enrolment in external quality assurance programs is part of the accreditation process for medical laboratories in Australia, with the majority of Australian laboratories being enrolled in programs from RCPA Quality Assurance Programs Pty Limited, a company owned by the Royal College of Pathologists of Australasia. An important feature of these programs is that they have been developed with the involvement and contribution of the profession. For example, the Chemical Pathology programs are a joint venture between the company and the Australasian Association of Clinical Biochemists (AACB). Some of the unique features of the programs are the composition of the material, the use of target values, the structure and information in the reports and the use of the internet for data entry and data review. Over the past thirty years, the development of these programs has made a significant contribution to the quality of laboratories in Australia.     

Screening protein and nucleic acid sequences against libraries of patterns.

We describe programs that can screen nucleic acid and protein sequences against libraries of motifs and patterns. Such comparisons are likely to play an important role in interpreting the function of sequences determined during large scale sequencing projects. In addition we report programs for converting the Prosite protein motif library into a form that is compatible with our searching programs. The programs work on VAX and SUN computers.     

Addressing consumer grievances in medicine: policies and practices of newborn screening programs in the United States

Newborn screening programs collectively administer the largest genetic testing initiative in the United States. The redress of grievances is an important mechanism for consumers to provide input into clinical and public health programs. In this study, we evaluated mechanisms for addressing consumer grievances in newborn screening programs. To do this, we surveyed all 50 state plus the District of Columbia newborn screening programs by questionnaire regarding protocols for receipt and redress of problems reported by parents of newborns and ascertained the existence and nature of complaints and how complaints were documented and addressed. Pertinent state and federal legislation and regulation were also reviewed. Six of 49 newborn screening programs reported having formal policies for handling consumer grievances. Four states reported having pertinent legislation or regulation. Thirty-eight of 49 states reported having received complaints from 1993 to 1995. Thirteen of 49 newborn screening programs reported that they actively seek feedback from consumers. Consumer grievances ranged from minor complaints to potentially life-threatening concerns. In general, complaints are managed on an ad hoc basis; formal policies are typically lacking. As newborn screening programs affect a vast number of Americans, a proactive and comprehensive approach, including solicitation of consumer feedback, could benefit both newborn screening programs and the public served by them.     

The current status and portability of our sequence handling software.

I describe the current status of our sequence analysis software. The package contains a comprehensive suite of programs for managing large shotgun sequencing projects, a program containing 61 functions for analysing single sequences and a program for comparing pairs of sequences for similarity. The programs that have been described before have been improved by the addition of new functions and by being made very much easier to use. The major interactive programs have 125 pages of online help available from within them. Several new programs are described including screen editing of aligned gel readings for shotgun sequencing projects; a method to highlight errors in aligned gel readings, new methods for searching for putative signals in sequences. We use the programs on a VAX computer but the whole package has been rewritten to make it easy to transport it to other machines. I believe the programs will now run on any machine with a FORTRAN77 compiler and sufficient memory. We are currently putting the programs onto an IBM PC XT/AT and another micro running under UNIX.     

Evaluation of Gene Structure Prediction Programs

We evaluate a number of computer programs designed to predict the structure of protein coding genes in genomic DNA sequences. Computational gene identification is set to play an increasingly important role in the development of the genome projects, as emphasis turns from mapping to large-scale sequencing. The evaluation presented here serves both to assess the current status of the problem and to identify the most promising approaches to ensure further progress. The programs analyzed were uniformly tested on a large set of vertebrate sequences with simple gene structure, and several measures of predictive accuracy were computed at the nucleotide, exon, and protein product levels. The results indicated that the predictive accuracy of the programs analyzed was lower than originally found. The accuracy was even lower when considering only those sequences that had recently been entered and that did not show any similarity to previously entered sequences. This indicates that the programs are overly dependent on the particularities of the examples they learn from. For most of the programs, accuracy in this test set ranged from 0.60 to 0.70 as measured by the Correlation Coefficient (where 1.0 corresponds to a perfect prediction and 0.0 is the value expected for a random prediction), and the average percentage of exons exactly identified was less than 50%. Only those programs including protein sequence database searches showed substantially greater accuracy. The accuracy of the programs was severely affected by relatively high rates of sequence errors. Since the set on which the programs were tested included only relatively short sequences with simple gene structure, the accuracy of the programs is likely to be even lower when used for large uncharacterized genomic sequences with complex structure. While in such cases, programs currently available may still be of great use in pinpointing the regions likely to contain exons, they are far from being powerful enough to elucidate its genomic structure completely.     

The specialty match: a necessity in the equitable resident selection process.

For many years directors of Canadian postgraduate specialty programs have selected candidates in an uncontrolled and haphazard way. Candidates and programs alike have therefore been unfairly treated. Since 1986 the Canadian Intern and Resident Matching Service has offered a centrally coordinated matching program to allow candidates to select specialty programs at centres of their choice and program directors to rate candidates. The result has been an effective method to achieve fairness in the selection of postgraduate trainees for participating Canadian specialty programs.

EMOTIONALLY DISTURBED CHILDREN AND ADOLESCENTS—California State Department of Mental Hygiene Programs

Through programs that are directly operated by the state and through subsidy programs using state funds and federal funds, the Department of Mental Hygiene in California provides services for children and adolescents who are emotionally disturbed. Private institutions for these purposes, in the form of residential centers and day care centers, are licensed by the Department of Mental Hygiene. Direct services provided by the Department of Mental Hygiene include residential treatment programs and outpatient clinic services.There have been increased demands for more residential treatment programs and for services for rural areas. Indications have been noted of increased need for research on questions dealing with services of this kind and increased training programs to provide adequate numbers of trained personnel.     

Preventing out-of-home placement for high-risk children

Preventing the removal of high-risk children from their families is investigated through two community-based programs. One program followed a day treatment model; the other used a home-based approach. These programs treated populations that shared common features but also had important differences. In both programs, a high percentage of children were maintained in the home and were still at home one year after discharge. It is suggested that such community-based intervention programs enhance the likelihood that high-risk children can remain with their families.     

Comparison of different approaches and computer programs for progress curve analysis of enzyme kinetics

For the analysis of enzyme kinetics, a variety of programs exists. These programs apply either algebraic or dynamic parameter estimation, requiring different approaches for data fitting. The choice of approach and computer program is usually subjective, and it is generally assumed that this choice has no influence on the obtained parameter estimates. However, this assumption has not yet been verified comprehensively. Therefore, in this study, five computer programs for progress curve analysis were compared with respect to accuracy and minimum data amount required to obtain accurate parameter estimates. While two of these five computer programs (MS‐Excel, Origin) use algebraic parameter estimation, three computer programs (Encora, ModelMaker, gPROMS) are able to perform dynamic parameter estimation. For this comparison, the industrially important enzyme penicillin amidase (EC 3.5.1.11) was studied, and both experimental and in silico data were used. It was shown that significant differences in the estimated parameter values arise by using different computer programs, especially if the number of data points is low. Therefore, deviations between parameter values reported in the literature could simply be caused by the use of different computer programs.     

Management of insecticides for use in disease vector control: Lessons from six countries in Asia and the Middle East

Interventions to control the vectors of human diseases, notably malaria, leishmaniasis and dengue, have relied mainly on the action of chemical insecticides. However, concerns have been raised regarding the management of insecticides in vector-borne disease-endemic countries. Our study aimed to analyze how vector control insecticides are managed in selected countries to extract lessons learned.A qualitative analysis of the situation of vector control insecticides management was conducted in six countries. Multi-stakeholder meetings and key informer interviews were conducted on aspects covering the pesticide lifecycle. Findings were compared and synthesized to extract lessons learned. Centrally executed guidelines and standards on the management of insecticides offered direction and control in most malaria programs, but were largely lacking from decentralized dengue programs, where practices of procurement, application, safety, storage, and disposal were variable between districts. Decentralized programs were better at facilitating participation of stakeholders and local communities and securing financing from local budgets. However, little coordination existed between malaria, visceral leishmaniasis and dengue programs within countries. Entomological capacity was concentrated in malaria programs at central level, while dengue and visceral leishmaniasis programs were missing out on expertise. Monitoring systems for insecticide resistance in malaria vectors were rarely used for dengue or visceral leishmaniasis vectors. Strategies for insecticide resistance management, where present, did not extend across programs or sectors in most countries. Dengue programs in most countries continued to rely on space spraying which, considering the realities on the ground, call for revision of international guidelines.Vector control programs in the selected countries were confronted with critical shortcomings in the procurement, application, safety measures, storage, and disposal of vector control insecticides, with implications for the efficiency, effectiveness, and safety of vector control. Further international support is needed to assist countries in situation analysis, action planning and development of national guidelines on vector control insecticide management.     

Opportunity gaps in out-of-school learning: How structural and process features of programs relate to race and socioeconomic status

Abstract

Out-of-school learning programs can be a context for positive development and learning for children and youth. However, research points to potential racial and socioeconomic disparities, or opportunity gaps, in this context. In this study, we use survey and video data from 106 staff across 30 out-of-school programs to examine how three features, staff, activities, and adult–child interactions, differ based on the racial and socioeconomic makeup of programs. We find that staff at programs serving children from low-income families on average have less experience and education. Also, programs serving children from African American and low-income families tend to offer more academic-focused activities. Finally, we found no differences in adult–child interaction quality across programs in the sample. Our findings suggest that a racial and socioeconomic opportunity gap may exist in the out-of-school context. This has implications for educational equity and the positive development of children that participate in this context.     

Dolphin Shows and Interaction Programs: Benefits for Conservation Education?

Dolphin shows and dolphin interaction programs are two types of education programs within zoological institutions used to educate visitors about dolphins and the marine environment. The current study examined the short‐ and long‐term effects of these programs on visitors' conservation‐related knowledge, attitude, and behavior. Participants of both dolphin shows and interaction programs demonstrated a significant short‐term increase in knowledge, attitudes, and behavioral intentions. Three months following the experience, participants of both dolphin shows and interaction programs retained the knowledge learned during their experience and reported engaging in more conservation‐related behaviors. Additionally, the number of dolphin shows attended in the past was a significant predictor of recent conservation‐related behavior suggesting that repetition of these types of experiences may be important in inspiring people to conservation action. These results suggest that both dolphin shows and dolphin interaction programs can be an important part of a conservation education program for visitors of zoological facilities.

Lessons from seven sustainability indicator programs in developing countries of Asia

Sustainability indicator programs in developing countries are the poor cousin of ecological indicator research. While an enormous number of indicators for the monitoring of sustainable development exists, few meta-evaluations on these measurements have been conducted in developing countries. Yet, researchers developing new programs face the question: how shall we design our monitoring instrument to respond to the local challenges.By presenting a qualitative meta-performance evaluation of seven sustainability indicator programs on the municipal level in developing countries of Asia, we identify crucial success factors in this contribution. The research draws on 41 expert interviews in Indonesia, Thailand, China, and India, as well as on program-related documents. In the presented case studies, local contexts are intended to be diverse: obtained results should map success factors in different settings. A context-related list of good-practice factors is derived from the interview material via a Qualitative Content Analysis and assessed against the data.We identify crucial strengths and weaknesses of sustainability indicator programs in six dimensions and link the success factors to their contexts. The results include innovative approaches to indicator types, data collection and data quality control, and a correlation between the anchoring of programs in approved development plans and long-term implementation. The results can provide valuable guidance to users of existing sustainability indicator programs and planners of new programs.     

An analysis of gene-finding programs for Neurospora crassa.

MOTIVATION: Computational gene identification plays an important role in genome projects. The approaches used in gene identification programs are often tuned to one particular organism, and accuracy for one organism or class of organism does not necessarily translate to accurate predictions for other organisms. In this paper we evaluate five computer programs on their ability to locate coding regions and to predict gene structure in Neurospora crassa. One of these programs (FFG) was designed specifically for gene-finding in N.crassa, but the model parameters have not yet been fully 'tuned', and the program should thus be viewed as an initial prototype. The other four programs were neither designed nor tuned for N.crassa. RESULTS: We describe the data sets on which the experiments were performed, the approaches employed by the five algorithms: GenScan, HMMGene, GeneMark, Pombe and FFG, the methodology of our evaluation, and the results of the experiments. Our results show that, while none of the programs consistently performs well, overall the GenScan program has the best performance on sensitivity and Missing Exons (ME) while the HMMGene and FFG programs have good performance in locating the exons roughly. Additional work motivated by this study includes the creation of a tool for the automated evaluation of gene-finding programs, the collection of larger and more reliable data sets for N.crassa, parameterization of the model used in FFG to produce a more accurate gene-finding program for this species, and a more in-depth evaluation of the reasons that existing programs generally fail for N.crassa. AVAILABILITY: Data sets, the FFG program source code, and links to the other programs analyzed are available at http://jerry.cs.uga.edu/~wang/genefind.html. CONTACT: eileen@cs.uga.edu.     

Feeding neural networks in the mollusc Aplysia

Aplysia feeding is striking in that it is executed with a great deal of plasticity. At least in part, this flexibility is a result of the organization of the feeding neural network. To illustrate this, we primarily discuss motor programs triggered via stimulation of the command-like cerebral-buccal interneuron 2 (CBI-2). CBI-2 is interesting in that it can generate motor programs that serve opposing functions, i.e., programs can be ingestive or egestive. When programs are egestive, radula-closing motor neurons are activated during the protraction phase of the motor program. When programs are ingestive, radula-closing motor neurons are activated during retraction. When motor programs change in nature, activity in the radula-closing circuitry is altered. Thus, CBI-2 stimulation stereotypically activates the protraction and retraction circuitry, with protraction being generated first, and retraction immediately thereafter. In contrast, radula-closing motor neurons can be activated during either protraction or retraction. Which will occur is determined by whether other cerebral and buccal neurons are recruited, e.g. radula-closing motor neurons tend to be activated during retraction if a second CBI, CBI-3, is recruited. Fundamentally different motor programs are, therefore, generated because CBI-2 activates some interneurons in a stereotypic manner and other interneurons in a variable manner.
