Forecast accuracy of Australian subnational population projections.

The authors assess demographic projections made over the last 20 years for Australia. "This paper first considers the role of accuracy amongst other objectives of projection activity. Accepting accuracy as a legitimate goal, we then assess the performance of 48 sets of population projections and forecasts for states and territories of Australia prepared since 1970. Projection accuracy is assessed by reference to length of forecast horizon, population size and rate of growth. We also examine the main sources of forecast error in selected projections for each state and compare the performance of past projections with alternatives based on simple extrapolation of contemporary population trends."

Method of stochastic prediction of population estimates based on Kendall's birth and death process.

"An attempt has been made to incorporate density and time-dependent birth and death rates into the generalized birth and death process given by Kendall (1948). The probability generating function of the process has also been investigated. A simple method of estimating the parameters of the process has been illustrated in the text. The applicability of the method for predicting the population of India, starting from the several deterministic projection figures given for any base year, is also discussed in the text."

The Caribbean Animal and Plant Information Network.

The Inter-American Institute for Cooperation on Agriculture (IICA) is presently implementing a four-year project in the Caribbean region to establish a regional information network on animal and plant health--the Caribbean Animal and Plant Health Information Network (CARAPHIN). CARAPHIN's immediate goal is to give the participating countries the technical capability to process and analyze the phyto- and zoo-sanitary information that they generate, share this information within the region, and use it as an effective instrument for decision making for agricultural development and trade. Sharing of information is further facilitated through the periodic regional and hemispheric meetings organized by IICA, by the Inter-American Animal Health Commission, and by the Technical Advisory Committee on Plant Protection. The Veterinary and Plant Protection Services of the region have expressed interest in the continuation of CARAPHIN as a permanent mechanism for agricultural health information management in the Caribbean. This motivated IICA to seek financing for a second phase of CARAPHIN, which will be executed from 1992 through 1996. Phase II of the project will seek to ensure the continuing application of the techniques and methodologies acquired by the agricultural health services of the different countries, and the functioning of the disease/pest information systems at the regional level. This will be achieved through technical assistance, continuing education, publications, provision of useful databases, and transfer of the project to a regional institution.

Online data collection with special populations over the World Wide Web.

The quick ascendance of the World Wide Web as the dominant vehicle for internet communication has recently made experimentation in a multimedia environment feasible on the Internet. Although web sites containing online psychology demonstrations and experiments for non-handicapped individuals have appeared in recent years (especially in the areas of cognitive and social psychology), there appear to have been few attempts to conduct online experimentation with special populations. We recently completed two online pilot studies of families with Down syndrome or Williams syndrome members: a) A survey that asks (via Likert rating scales, adjective checklists, multiple-choice style questions, and text-entry boxes) about family background, computer use, and temperament of the special needs family member; and b) An experiment (completed by an individual with special needs) that includes auditory and visual digit span tasks and a memory-for-orientation task in which responses are entered via mouse clicks. Recruiting began with e-mail announcements to representative Down syndrome and Williams syndrome discussion groups, listserves, and bulletin boards, and submission of the project's URL (http://www.cofc.edu/~marcellm/testaw.htm) and key indexing terms to selected search engines. This paper reviews technical aspects of developing the online programmes as well as the strengths and weaknesses of online vs. traditional laboratory-based research in relation to issues such as experimental control, delivery of instructions, experimenter bias, participant recruitment, sample heterogeneity, generalization, attrition, privacy, financial costs, data integrity, and ethics. We conclude by offering our thoughts on two ways of implementing online experimentation with special populations: a) Using a remote parent 'helper' as a proxy to work with the target individual; and b) Collaborating with professional colleagues in Web-based projects conducted in traditional laboratory settings.

[[A projection system for future age-specific fertility rates]].

"This paper presents detailed description of a newly developed fertility projection system which was used in population projections for Japan, and population projections by prefectures, officially announced in September and November 1992 respectively. The system is based on a model of age-specific fertility rates by birth order, and it converts parameters which convey behavioral traits of cohort fertility into age-specific fertility rates of future years."

Clinical field follow-up of high density polyethylene (HDPE)-Jaipur prosthetic technology for trans-tibial amputees.

The purpose of this study was to examine the outcome of the application of the High Density Polyethylene (HDPE)-Jaipur prosthetic construction in fitting trans-tibial amputees in a number of projects in the developing world. Projects in Honduras, Uganda and India were visited. Three hundred and twenty (320) patients had been provided with a HDPE-Jaipur prosthesis and of these 172 were seen for a technical and clinical follow-up after a median of 35 months. More than half the amputations were due to trauma, the remainder to disease. Fabrication and fitting in the three projects was carried out by individuals who had undertaken a twice week training course provided by Bhagwan Mahaveer Viklang Sahayata Samiti limb centre in Jaipur. The individuals involved had limited background training in prosthetics. Craftsmanship and fit were assessed as being poor in 56% of cases. The technical quality of the Jaipur foot was considered acceptable as its performance was better than previously observed results. Although there was patient satisfaction of 85% and compliance of 94% the HDPE-Jaipur trans-tibial system was not considered acceptable as 49% reported walking distances less than 1km and 36% discomfort. The major inadequacy in outcome relates to the use for fabrication and fitting of individuals with inadequate education and training.

[Operating room assistance: an innovative practice].

Professional practice changes in the operating room have led to the development of a new role for nurses--as surgical assistants. Essentially, the surgical assistant nurse helps ensure the patient's safety while providing technical and clinical assistance to the surgeon in such areas as exposing and manipulating tissues, suturing fascia and using various specialized instruments. The surgical assistant nurse function is being implemented through a pilot project at the Institut de cardiologie de Montréal. Developed by representatives of the nursing and surgical departments there, the project was approved by the Collège des médecins du Québec in April 1995 and subsequently by the institute's council of physicians, dentists and pharmacists. It has also gained recognition from the Ordre des infirmières et infirmiers du Québec (OIIQ). The pilot project incorporated a 186-hour training program, which was delivered from May to September 1995 according to three distinct learning modules: maintenance of a safe environment for the patient, clinical assistance and technical assistance. A tutorial approach to learning included individual and team work, simulation exercises, technical courses, lab work and practical training in the operating room. At the end of the training program, two surgical assistant nurses began practising in their new role. An evaluation of the project will be performed in September 1996.

Regional economic-demographic modelling and projection: review of an international conference.

A review of the papers presented at the International Conference on Forecasting Regional Population Change and Its Economic Determinants and Consequences, held at Airlie House, Virginia, from May 26 to 29, 1982, is provided. "This review...concludes that [regional economic-demographic] modelling is at an early stage of development and currently provides only an adjunct to more conventional methods of regional forecasting. Given expected future improvements in the theory, data and techniques of economic-demographic modelling, such models could soon provide a worthwhile alternative."

Creating a web-enhanced interactive preclinic technique manual: case report and student response.

This article describes the development, use, and student response to an online manual developed with off-the-shelf software and made available using a web-based course management system (Blackboard) that was used to transform a freshman restorative preclinical technique course from a lecture-only course into an interactive web-enhanced course. The goals of the project were to develop and implement a web-enhanced interactive learning experience in a preclinical restorative technique course and shift preclinical education from a teacher-centered experience to a student-driven experience. The project was evaluated using an anonymous post-course survey (95 percent response rate) of 123 freshman students that assessed enabling (technical support and access to the technology), process (the actual experience and usability), and outcome criteria (acquisition and successful use of the knowledge gained and skills learned) of the online manual. Students responded favorably to sections called "slide galleries" where ideal and non-ideal examples of projects could be viewed. Causes, solutions, and preventive measures were provided for the errors shown. Sections called "slide series" provided cookbook directions allowing for self-paced and student-directed learning. Virtually all of the students, 99 percent, found the quality of the streaming videos adequate to excellent. Regarding Internet connections and video viewing, 65 percent of students successfully viewed the videos from a remote site; cable connections were the most reliable, dial-up connections were inadequate, and DSL connections were variable. Seventy-three percent of the students felt the videos were an effective substitute for in-class demonstrations. Students preferred video with sound over video with subtitles and preferred short video clips embedded in the text over compilation videos. The results showed it is possible to develop and implement web-enhanced and interactive dental education in a preclinical restorative technique course that successfully delivered information beyond the textual format.

Can general practice provide useful information?--evaluation of a primary health care information project in northern England.

OBJECTIVE: To develop a computerised primary care information gathering network capable of producing reliable risk factor and morbidity data from a wide diversity of general practice software systems. METHOD: Fourteen practices from the Wakefield and Pontefract district collaborated in sharing information and solving technical difficulties associated with collecting data on coronary heart disease (CHD) risk factors, diabetes, and asthma. Practices also participated in rheumatology and mental health needs assessment projects. RESULTS: Data could be transferred by diskette in only five of the systems and paper reports had to be used to post process the data into a standard format. Not all data were complete or comparable. Crude estimates only of smoking prevalence and smoking cessation interventions were possible, as well as of age and sex specific prevalences for asthma and diabetes. The rheumatology health needs assessment, using the prospective collection of consultation based data, highlighted an unmet need for rheumatology services in the community. CONCLUSIONS: Although practices have been willing to devote considerable time and effort to the project, the diversity of software has precluded a simple methodology for data collection and analysis. The amount of useful information retrieved so far, has been limited but a number of important lessons have been learned which have implications for similar information projects and the use of primary care information in service planning.

MedCERTAIN: quality management, certification and rating of health information on the Net.

MedCERTAIN (MedPICS Certification and Rating of Trustworthy Health Information on the Net, http://www.medcertain.org/) is a recently launched international project funded under the European Union's (EU) "Action Plan for safer use of the Internet. It provides a technical infrastructure and a conceptual basis for an international system of "quality seals", ratings and self-labelling of Internet health information, with the final aim to establish a "trustmark" for networked health information. Digital "quality seals" are evaluative metadata (using standards such as PICS = Platform for Internet Content Selection, now being replaced by RDF/XML) assigned by trusted third-party raters. The project also enables and encourages self-labelling with descriptive meta-information by web authors. Together these measures will help consumers as well as professionals to identify high-quality information on the Internet. MedCERTAIN establishes a fully functional demonstrator for a self- and third-party rating system enabling consumers and professionals to filter harmful health information and to positively identify and select high quality information. We aim to provide a system which allows citizens to place greater trust in networked information, exemplified in the domain of health information, whilst also making a significant contribution for similar projects with different target domains. The project will demonstrate how PICS-based content rating and filtering technologies can automate and exploit value-adding resource description services. It further proposes standards for interoperability of rating services.

Midbrain projections to the trigeminal, facial and hypoglossal nuclei in the opossum. A study using axonal transport techniques.

It has been proposed (see Berntson and Micco for review) that circuits intrinsic to the midbrain play an important role in the elaboration and control of behaviors involving the motor nuclei of the trigeminal, facial and hypoglossal nerves (e.g. defense, threat, attack); but because of technical problems, it has been difficult to analyze their organization. Using the horseradish peroxidase technique we have localized those midbrain neurons which project to each of the above nuclei and by using the autoradiographic method we have plotted the intranuclear distribution of their axons. Using both techniques, we have seen that mesencephalic projections to oral-facial motor nuclei strongly favor the nucleus of the facial nerve. Cells ventral to the cerebral aqueduct, including the ventral periaqueductal gray, the interstitial nucleus of Cajal, the nucleus of Darkshchewitsch and the rostral oculomotor nucleus provide major midbrain-facial projections in the opossum. Their axons terminate densely and bilaterally within areas innervating auricular muscles and to a lesser extent, the platysma sheet. The projection to the caudal auricular area of the facial complex is particularly dense. Neurons within and dorsal to the red nucleus project to regions of the contralateral facial nucleus reported to supply buccolabial, zygomatic and cervical musculature. There is also a minor tectal projection to the facial nucleus. Direct projections to the hypoglossal nuclei also arise within the periaqueductal gray and interstitial nucleus, but if such regions influence the motor trigeminal nucleus, it is mainly by way of dendrites that extend outside the nucleus or by at least one synaptic delay. The mesencephalic nucleus of the trigeminal nerve, however, projects strongly to the motor trigeminal nucleus. These data are discussed in light of their possible functional significance.

[Promoting competence in a model trial of a complementary course of study in health sciences/public health at the Berlin Technical University in cooperation with the Free University and other science and general practice institutions].

Since October 1992 (winter semester 92/93) graduates are being educated in Public Health at Berlin Technical University in cooperation with the Free University of Berlin as well as with the Humboldt University of Berlin and other institutions of science and practice in Berlin and Brandenburg. For the time being the course of studies is a pilot project for 4 years. The aim of the postgraduate studies is the creation of permanent structures and therefore institutionalisation. It is open to graduates and college graduates of public-health relevant subject areas of specialisation are "Health Promotion in the community and at the workplace" and "Planning and Management in Health Services". The course of studies takes 4 semesters and is divided into basic studies, studies of main points of emphasis and project studies. Social medicine and especially epidemiology are part of the basic disciplines, which are indispensable for finding the way of looking at problems concerning public health. The reason for the peculiarity with regard to establishing public health at other German universities are the main topics representing the interaction between the technical and ecological development of health. The graduate degree is "Magister of Public Health". During the time of the pilot project the course of studies is subjected to external and internal surveillance regarding quality assurance and quality optimisation of teaching and organisation of the studies. On the one hand this is done by an external advisory committee and on the other hand by internal and external evaluation.

Projections of households and household populations by household size propensities.

"This paper describes a method for constructing projections of numbers of households of various types and the numbers of people in that structure. The method uses the concept of household size propensity.... Using data from the 1981 and 1986 Censuses and population projections to the year 2011, the method produces projections of Australian households and household populations by size of household for five-year intervals from 1991 to 2011."
