An Australian Perspective on Singaporean Welfare Policy

From a Western perspective, Singapore appears to be an overt example of a neo-liberal welfare regime based on low social expenditure, and limited and discretionary social assistance. But the true picture is arguably more complex. Singapore’s welfare policy is driven by strong cultural assumptions around individual and family self-reliance, and the inappropriateness of state welfare provision. However, there is also a strong emphasis on communal responsibility for supporting the disadvantaged. Some conclusions are drawn about the limitations of existing policies, and possible new directions for the future.

MAS Integration and Controllership Effectiveness: Evidence of a Preparer-User Perception Gap

Recent evidence suggests that managers establish a positive link between management accounting system (MAS) integration and controllership effectiveness, which is fully mediated by the perceived consistency of financial language. Our paper extends this research by analyzing whether controllers have similar perceptions on MAS design. Testing a series of multi-group structural equation models, we find evidence for a preparer-user perception gap with respect to the mediating impact of a consistent financial language. Our results contribute to the still-ongoing controversial debate on MAS integration by indicating that the effectiveness of MAS design cannot be evaluated solely from an instrumental perspective independent from users’ perceptions.

Assessment of bone channels other than the nasopalatine canal in the anterior maxilla using limited cone beam computed tomography

PURPOSE The anterior maxilla, sometimes also called premaxilla, is an area frequently requiring surgical interventions. The objective of this observational study was to identify and assess accessory bone channels other than the nasopalatine canal in the anterior maxilla using limited cone beam computed tomography (CBCT). METHODS A total of 176 cases fulfilled the inclusion criteria comprising region of interest, quality of CBCT image, and absence of pathologic lesions or retained teeth. Any bone canal with a minimum diameter of 1.00 mm other than the nasopalatine canal was analyzed regarding size, location, and course, as well as patient gender and age. RESULTS A total of 67 accessory canals ≥1.00 mm were found in 49 patients (27.8%). A higher frequency of accessory canals was observed in males (33.0%) than in females (22.7%) (p = 0.130). Accessory canals occurred more frequently in older rather than younger patients (p = 0.115). The mean diameter of accessory canals was 1.31 ± 0.26 mm (range 1.01-2.13 mm). Gender and age did not significantly influence the diameter. Accessory canals were found palatal to all anterior teeth, but most frequently palatal to the central incisors. In 56.7%, the accessory canals curved superolaterally and communicated with the ipsilateral alveolar extension of the canalis sinuosus. CONCLUSIONS The study confirms the presence of bone channels within the anterior maxilla other than the nasopalatine canal. More than half of these accessory bone canals communicated with the canalis sinuosus. From a clinical perspective, studies are needed to determine the content of these accessory canals.

Measuring Information Quality on the Internet - a User Perspective

Research into information quality on the internet, in particular on websites, has become increasingly important in recent years. In this paper a research project is described in which a measurement instrument was developed that enables the information quality of websites to be determined and analyzed from the customer perspective. The measurement instrument was developed in several stages and on the basis of a methodical-theoretical approach. In a first step, previous research results and measurement instruments were systematically analyzed. In a second step, these results were adjusted and supplemented on the basis of a qualitative study. A quantitative test of the measurement instrument is planned.

Gynophobia and Anti-republicanism in Thomas Mann's Doctor Faustus

Why does Adrian Leverkühn choose a Shakespeare play for his major first and his first twelve-tone composition? Why in particular a Shakespeare comedy? And why, of all comedies, Love’s Labour’s Lost? Why does he start working on it in Munich? Why does his work there soon come to a halt? Why does it prosper only in Italy? And why does he eventually return to Upper Bavaria so as to complete it? Why is he said to have completed the opera exactly one hundred years ago? And why, finally, is it first performed only after the outbreak of the war and then, surprisingly, in a German adaptation? In order to answer these and similar questions, this paper sets out to re-contextualise Doktor Faustus with regard to discourse history and re-read the novel from a gender-theoretical perspective. The leading hypothesis is that Thomas Mann’s novel belongs to the proto-history of feminist Shakespeare reception, an assumption to be substantiated through an analysis of settings, locations and the constructions of space.

A costing exercise of provision of prevention of HIV transmission from mother to child services in Vietnam

Objectives. This dissertation focuses on estimating the cost of providing a minimum package of prevention of mother-to-child HIV transmission (PMTCT) in Vietnam from a societal perspective and discussing the issues of scaling-up the minimum package nationwide. ^ Methods. Through collection of cost-related data of PMTCT services at 22 PMTCT sites in 5 provinces (Hanoi, Quang Ninh, Thai Nguyen, Hochiminh City, and An Giang) in Vietnam, the research investigates the item cost of each service in minimum PMTCT packages and the actual cost per PMTCT site at different organizational levels including central, provincial, and district. Next, the actual cost per site at each organizational level is standardized by adjusting for HIV prevalence rate to arrive at standardized costs per site. This study then uses the standardized costs per site to project, by different scenarios, the total cost to scale-up the PMTCT program in Vietnam. ^ Results. The cost for HIV tests, infant formula, and salary of health workers are consistently found to be the biggest expenditures in the PMTCT minimum package program across all organizational levels. Annual cost for drugs for prophylaxis treatment, operating and capital, and training costs are not substantial (less than 5% of total costs at all levels). The actual annual estimated cost for a PMTCT site at the central level is nearly VND 1.9 billion or US$ 107,650 (exchange rate US$ 1 = VND 17,500) while the annual cost for a provincial site is VND 375 million or US$ 21,400. The annual cost for a district site is VND 139 million (∼US$ 8,000). ^ The estimated total annual cost to roll out the PMTCT minimum package to the 5 studied provinces is approximately US$ 1.1 million. If the PMTCT program is to be scaled-up to 14 provinces until 2008 and up to 40 provinces through the end of 2010 as planned by the Ministry of Health, it would cost the health system an approximate annual amount of US$ 2.1 million and US$ 5.04 million, respectively. The annual cost for scaling-up the PMTCT minimum package nationwide is around US$ 7.6 million. Meanwhile, the total annual cost to implement PMTCT minimum packages to achieve PMTCT national targets in 2010 (providing counseling service to 90% of all pregnant women; 60% of them will receive HIV tests and 100% of HIV (+) mother and their newborn will receive prophylaxis treatment) would be US$ 6.1 million. ^ Recommendations. This study recommends: (1) the Ministry of Health of Vietnam should adjust its short-term national targets to a more feasible and achievable level given the current level of available resources; (2) a detailed budget for scaling-up the PMTCT program should be developed together with the national PMTCT action plan; (3) the PMTCT scaling-up plan developed by the Ministry of Health should focus on coverage of high prevalence population and quality of services provided rather than number of physical provinces reached; (4) exclusive breastfeeding strategy should be promoted as part of the PMTCT program; and (5) for a smooth and effective rolling out of PMTCT services nationwide, development of a national training plan and execution of this plan must precede any other initiations of the PMTCT scaling-up plan. ^

PREPAID MENTAL HEALTH SERVICES: A NATIONAL PERSPECTIVE

The purpose of this 1982 national survey of all operational prepaid health plans, or PHPs (including health maintenance organizations), was to provide information on the current coverage of PHP mental health and substance abuse services, benefits and service provision, general and mental health organization characteristics, mental health service costs, and physical and mental health service utilization.^ Two survey instruments were designed, pretested and distributed to all operational PHPs throughout the United States. A total of 237 PHPs were surveyed, of which 205 (86.50 percent) completed and returned both questionnaires.^ One result of the rapid growth in the PHP field over the past ten years has been the expansion in both the number of PHPs as well as the organizational characteristics of these PHPs. However, little attention in the research literature has been given to the application of empirical results to the PHP arrangements. This project has attempted to contribute to current knowledge regarding prepaid mental health services from a national perspective, and explore, on a preliminary descriptive basis, the variety of potential service delivery arrangements for physical and mental health services (total services) and for mental health services.^ The study emphasized that PHPs must continue to monitor the costs and utilization of mental health services, particularly in light of the apparent elimination of data collection and statistical summary responsibilities within the federal government regarding PHP activities as well as the proposed legislation to eliminate mandated mental health and substance abuse services from basic health plan benefits for federally qualified PHPs. ^

Cost-effectiveness analysis of stereotactic body radiotherapy and radiofrequency ablation for medically inoperable liver metastases from colorectal cancer

This report describes the development of a Markov model for comparing percutaneous radiofrequency ablation (RFA) and stereotactic body radiation therapy (SBRT) in terms of their cost-utility in treating isolated liver metastases from colorectal cancer. The model is based on data from multiple retrospective and prospective studies, available data on different utility states associated with treatment and complications, as well as publicly available Medicare costs. The purpose of this report is to establish a well-justified model for clinical management decisions. In comparison with SBRT, RFA is the most cost-effective treatment for this patient population. From the societal perspective, SBRT may be an acceptable alternative with an ICER of $28,673/QALY. ^

Movimiento de mujeres/feminismo/s : tensiones y desafíos en la Argentina de los noventa

Durante la transición democrática y el primer período de consolidación, los movimientos sociales resurgen y juegan un rol protagónico como portavoces de la sociedad. El movimiento mujeres/feminismo también tiene aquí un nuevo florecimiento. Sin embargo, la “globalización" traerá aparejada algunas consecuencias que repercutirán tanto en el Estado como en el movimiento, dos de los actores/as protagónicos en la definición de políticas públicas con perspectiva de género. Cuáles son los desafíos que se vislumbran, desde el movimiento de mujeres, en orden a la concesión de una ciudadanía plena para las mujeres, luego de esos cambios, es la pregunta que recorre el texto.

Effect of Prosopis flexuosa on understory species and its importance to pastoral management in woodlands of the Central Monte Desert

In the Monte Biogeographic Province, located in the arid region of Argentina, the presence of Prosopis flexuosa DC. produces spatial heterogeneity through edaphic modifications and microclimate changes. This results in vegetation patches differing in species composition and abundance. However, this interaction can be modified by the occurrence of gradients of biotic stress or disturbance intensity. In particular, grazing has been observed to enhance or reduce vegetation heterogeneity. Such complex of interactions could determine forage availability for cattle in one of the driest areas of the Monte Desert. We assessed the effect of Prosopis on understory species and analyzed whether the outcomes of this interaction differed with distance to watering points, as a proxy of grazing intensity, in the Northeast of Mendoza Province, Argentina. We used a two-way factorial design including the following factors: 1) microsite (under the cover of P. flexuosa trees and in intercanopy microsites) and 2) distance to watering points ("near the watering point", 500-700 m away, and "far from the watering point", 3-4 km away). Cover of each species, total cover, bare soil, and litter were recorded, and plant diversity, richness, and evenness were estimated with the modified Point Quadrat method. Results showed that P. flexuosa cover, distance from watering points, and the interaction between them determined species composition, abundance and spatial distribution of understory species, and were, consequently, a determining factor for forage availability. The presence of P. flexuosa enhances carrying capacity by supporting higher abundance of grasses under its canopy. Near watering points, high grazing intensity appears to disrupt the patches formed under P. flexuosa canopies, reducing the differences between microsites.

Two historical maps from nineteenth-century Palestine, with links to digitized maps in shapefile format

Reconstructing past landscapes from historical maps requires quantifying the accuracy and completeness of these sources. The accuracy and completeness of two historical maps of the same period covering the same area in Israel were examined: the 1:63,360 British Palestine Exploration Fund map (1871-1877) and the 1:100,000 French Levés en Galilée (LG) map (1870). These maps cover the mountainous area of the Galilee (northern Israel), a region with significant natural and topographical diversity, and a long history of human presence. Land-cover features from both maps, as well as the contours drawn on the LG map, were digitized. The overall correspondence between land-cover features shown on both maps was 59% and we found that the geo-referencing method employed (transformation type and source of control points) did not significantly affect these correspondence measures. Both maps show that in the 1870s, 35% of the Galilee was covered by Mediterranean maquis, with less than 8% of the area used for permanent agricultural cropland (e.g., plantations). This article presents how the reliability of the maps was assessed by using two spatial historical sources, and how land-cover classes that were mapped with lower certainty and completeness are identified. Some of the causes that led to observed differences between the maps, including mapping scale, time of year, and the interests of the surveyors, are also identified.

Radioisotope stratigraphy, sedimentology and geochemistry of Late Quaternary sediments from the Eastern Arctic Ocean

To reconstruct Recent and past sedimentary environments, marine sediments of Upper Pleistocene and Holocene ages from the eastern Arctic Ocean and especially from the Nansen-Gakkel Ridge (NGR) were investigated by means of radioisotopic, geochemical and sedimentological methods. In combination with mass physical property data and lithological analysis these investigations allow clearly to characterize the depositional environments. Age dating by using the radioisotope 230Th gives evidence that the investigated sediments from the NGR are younger than 250,000 years. Identical lithological sediment sequences within and between sediment cores from the NGR can be related to sedimentary processes which are clearly controlled by palaeoclimate. The sediments consist predominantly of siliciclastic, terrigenous ice-rafted detritus (IRD) deriving from assorted and redeposited sediments from the Siberian shelfs. By their geochemical composition the sediments are similar to mudstone, graywacke and arcose. Sea-ice as well as icebergs play a major roll in marine arctic sedimentation. In the NGR area rapid change in sedimentary conditions can be detected 128,000 years ago. This was due to drastic change in the kind of ice cover, resulting from rapid climatic change within only hundreds of years. So icebergs, deriving mostly from Siberian shelfs, vanished and sea-ice became dominant in the eastern Arctic Ocean. At least three short-period retreats of the shelf ice between 186,000 and 128,000 years are responsible for the change of coarse to fine-grained sediments in the NGR area. These warmer stages lasted between 1,000 and 3,000 years. By monitoring and comparing the distribution patterns of sedimentologic, mass physical and geochemical properties with 230Th ex activity distribution patterns in the sediment cores from the NGR, there is clear evidence that sediment dilution is responsible for high 230Th ex activity variations. Thus sedimentation rate is the controlling factor of 230Th ex activity variations. The 230Th flux density in sediments from the NGR seems to be highly dependent On topographic Position. The distribution patterns of chemical elements in sediment cores are in general governed by lithology. The derivation of a method for dry bulk density determination gave the opportunity to establish a high resolution stratigraphy on sediment cores from the eastern Arctic Ocean, based on 230Thex activity analyses. For the first time sedimentation and accumulation rates were determined for recent sediments in the eastern Arctic Ocean by 230Th ex analyses. Bulk accumulation rates are highly variable in space and time, ranging between 0.2 and 30 g/cm**2/ka. In the sediments from the NGR highly variable accumulation rates are related to the kind of ice cover. There is evidence for hydrothermal input into the sediments of the NGR. Hydrothermal activity probably also influences surficial sediments in the Sofia Basin. High contents of As are typical for surficial sediments from the NGR. In particular SL 370-20 from the bottom of the rift valley has As contents exceeding in parts 300 ppm. Hydrothermal activity can be traced back to at least 130,000 years. Recent to subrecent tectonic activity is documented by the rock debris in KAL 370 from the NGR. In four other sediment cores from the NGR rift valley area tectonically induced movements can be dated to about 130,000 years ago, related most probably to the rapid climate change. Processes of early diagenesis in sediments from the NGR caused the aobilization and redeposition of Fe, Mn and Mo. These diagenetic processes probably took place during the last 130,000 years. In sediment cores from the NGR high amounts of kaolinite are related to coarse grained siliciclastic material, probably indicating reworking and redeposition of siberian sandstones with kaolinitic binding material. In contrast to kaolinite, illite is correlated to total clay and 232Th contents. Aragonite, associated with serpentinites in the rift valley area of the NGR, was precipitated under cold bottom-water conditions. Preliminary data result in a time of formation about 60 - 80 ka ago. Manganese precipitates with high Ni contents, which can be related to the ultrabasic rocks, are of similar age.

Estándares, evaluación y currículo

Entre los enfoques actuales de los diseños curriculares de diferentes niveles educativos, el currículo basado en estándares es uno de los más difundidos. Su adopción es objeto de particular recomendación por algunos especialistas en política educativa y en diseño curricular. Acá se analizan los orígenes del uso del concepto de estándar en los campos de la evaluación y del currículo. El propósito no es hacer un estudio histórico de la cuestión sino mostrar, desde una perspectiva didáctica, algunos de los significados de este concepto cuando se emplean en estos dominios, así como sus posibles consecuencias deseadas y no deseadas.
