    Charity Basket or Revolution: Beliefs, Experiences, and Context in Preservice Teachers' Service Learning

    CURRICULUM INQUIRY, Issue 4 2000
    David M. Donahue
    Given what one observer calls the "vast disparity of definitions that faculty can bring to service learning,from what is basically the charity basket approach to the revolutionary," service learning can varytremendously, from reading to elderly residents of a nursing home to organizing a boycott of a sneaker company. With such diversity before teachers, what influences them in the way they design service learning? How do preservice teachers, for whom so many ideas about teaching are emerging, make such choices? Two case studies suggest that preservice teachers' beliefs, experiences, and the context where they teach play an important role related to if and how they use service learning. Beliefs and experiences are especially important because, although service learning is often presented as supporting apolitical values,empowerment and responsibility, for example,for which broad consensus exists, such values are also ambiguous and open to interpretation. Teacher educators and advocates of service learning need to acknowledge the ambiguous political nature of service and service learning. By doing so, they have an opportunity to make the political context of teaching explicit for preservice teachers. Such education in service learning for new teachers goes beyond "training" in the logistical and technical details of implementing a new pedagogy to thoughtful reflection on the value-laden act of teaching.

    Trends in affordability of the Illawarra Healthy Food Basket 2000,2007

    NUTRITION & DIETETICS, Issue 1 2009
    Peter WILLIAMS
    Abstract Aims:, The Illawarra Healthy Food Basket was developed as one measure to monitor the affordability of healthy eating in Australia. It consists of 57 items selected to meet the nutritional requirements of a reference family of five. The basket was first costed in the Illawarra region of Australia in 2000 and again in 2001 and 2003. The present study aimed to repeat the costing of the basket in 2005 and 2007 and to assess the trends in affordability since 2000. Methods:, Costing was carried out in the same five suburbs as previous surveys, using a large supermarket, greengrocer and butcher from each. Comparison data included: welfare entitlements obtained from Centrelink, average weekly earnings and the consumer price index for food. Main outcome measures:, The average weekly cost of the Illawarra Healthy Food Basket in 2005 and 2007, and trends in the costs compared with changes in average weekly earning and welfare benefits for the reference family. Results:, The total cost of the Illawarra Healthy Food Basket in 2007 was $242.49, an increase of 20.4% since 2000, with the greatest increases in the prices of vegetables (55.7%) and fruit (46.7%). Fruits, vegetables and meat were cheaper at independent grocers and butchers than in supermarkets. The percentage of average weekly earning or welfare payments required to purchase the Illawarra Healthy Food Basket remained stable at slightly below 30%. Conclusion:, These results indicate that the affordability of healthy eating has remained relatively constant from 2000 to 2007, but the significant increases in fruit and vegetable prices might be making healthy food choices more difficult.

    What Should the Weights of the Three Major Currencies be in a Common Currency Basket in East Asia?,

    ASIAN ECONOMIC JOURNAL, Issue 1 2006
    Kentaro Kawasaki
    F31; F33; F36; F42 We consider what type of regional common currency should be introduced in East Asia in the future. The common currency basket is, in itself, more desirable as an anchor currency. In this paper we define two types of currency basket and investigate the long-term sustainability of adopting a common currency basket in East Asia. From our empirical results, a larger weight (but less than 100 percent) for the US dollar in the common currency basket tends to make bilateral exchange rates among East Asian countries stable in the long run.

    The increasing cost of healthy food

    AUSTRALIAN AND NEW ZEALAND JOURNAL OF PUBLIC HEALTH, Issue 2 2010
    Michelle Harrison
    Abstract Objective: To assess changes in the cost and availability of a standard basket of healthy food items (the Healthy Food Access Basket [HFAB]) in Queensland. Methods: Analysis of five cross-sectional surveys (1998, 2000, 2001, 2004 and 2006) describes changes over time. Eighty-nine stores in five remoteness categories were surveyed during May 2006. For the first time a sampling framework based on randomisation of towns throughout the state was applied and the survey was conducted by Queensland Treasury. Results: Compared with the costs in major cities, in 2006 the mean cost of the HFAB was $107.81 (24.2%) higher in very remote stores in Queensland, but $145.57 (32.6%) higher in stores more than 2,000 kilometres from Brisbane. Over six years the cost of the HFAB has increased by around 50% ($148.87) across Queensland and, where data was available, by more than the cost of less healthy alternatives. The Consumer Price Index for food in Brisbane increased by 32.5% over the same period. Conclusions and Implications: Australians, no matter where they live, need access to affordable, healthy food. Issues of food security in the face of rising food costs are of concern particularly in the current global economic downturn. There is an urgent need to nationally monitor, but also sustainably address the factors affecting the price of healthy foods, particularly for vulnerable groups who suffer a disproportionate burden of poor health.

    The Dangers of Hanging Baskets: ,Regulatory Myths' and Media Representations of Health and Safety Regulation

    JOURNAL OF LAW AND SOCIETY, Issue 3 2009
    Paul Almond
    The successful enforcement of health and safety regulation is reliant upon the ability of regulatory agencies to demonstrate the legitimacy of the system of regulatory controls. While ,big cases' are central to this process, there are also significant legitimatory implications associated with ,minor' cases, including media-reported tales of pettiness and heavy-handedness in the interpretation and enforcement of the law. The popular media regularly report stories of ,regulatory unreasonableness', and they can pass quickly into mainstream public knowledge. A story's appeal becomes more important than its factual veracity; they are a form of ,regulatory myth'. This paper discusses the implications of regulatory myths for health and safety regulators, and analyses their challenges for regulators, paying particular attention to the Health and Safety Executive (HSE) which has made concerted efforts to address regulatory myths attaching to its activities. It will be shown that such stories constitute sustained normative challenges to the legitimacy of the regulator, and political challenges to the burgeoning regulatory state, because they reflect some of the key concerns of late-modern society.

    ALTERNATIVE METHODS IN THE ENDOSCOPIC MANAGEMENT OF DIFFICULT COMMON BILE DUCT STONES

    DIGESTIVE ENDOSCOPY, Issue 2010
    Dong Ki Lee
    The endoscopic method is accepted as a first treatment modality in the management of extrahepatic bile duct. Most large stones can be removed with basket and mechanical lithotripsy after endoscopic sphincterotomy. Currently, in treating large extrahepatic bile duct stones, endoscopic papillary large balloon dilation with mid-incision endoscopic sphincterotomy is actively performed instead of applying mechanical lithotripsy after full endoscopic sphincterotomy. Herein, we describe the conceptions, proper indications, methods and complications of endoscopic papillary large balloon dilation with regards to currently published reports. In addition, intracorporeal lithotripsy by peroral cholangioscopy with an ultra-slim upper endoscope is introduced, which is more convenient than previous conventional intracorporeal lithotripsy methods using mother,baby endoscopy or percutaneous transhepatic cholangioscopy. Lastly, biliary stenting with the choleretic agent administration method is briefly reviewed as an alternative treatment option for frail and elderly patients with large impacted common bile duct stones.

    The international monetary system in the last and next 20 years

    ECONOMIC POLICY, Issue 47 2006
    Barry Eichengreen
    SUMMARY The evolution of exchange rate regimes The last two decades have seen far-reaching changes in the structure of the international monetary system. Europe moved from the European Monetary System to the euro. China adopted a dollar peg and then moved to a basket, band and crawl in 2005. Emerging markets passed through a series of crises, leading some to adopt regimes of greater exchange rate flexibility and others to rethink the pace of capital account liberalization. Interpreting these developments is no easy task: some observers conclude that recent trends are confirmation of the ,bipolar view' that intermediate exchange rate arrangements are disappearing, while members of the ,fear of floating school' conclude precisely the opposite. We show that the two views can be reconciled if one distinguishes countries by their stage of economic and financial development. Among the advanced countries, intermediate regimes have essentially disappeared; this supports the bipolar view for the group of countries for which it was first developed. Within this subgroup, the dominant movement has been toward hard pegs, reflecting monetary unification in Europe. While emerging markets have also seen a decline in the prevalence of intermediate arrangements, these regimes still account for more than a third of the relevant subsample. Here the majority of the evacuees have moved to floats rather than fixes, reflecting the absence of EMU-like arrangements in other parts of the world. Among developing countries, the prevalence of intermediate regimes has again declined, but less dramatically. Where these regimes accounted for two-thirds of the developing country subsample in 1990, they account for a bit more than half of that subsample today. As with emerging markets, the majority of those abandoning the middle have moved to floats rather than hard pegs. The gradual nature of these trends does not suggest that intermediate regimes will disappear outside the advanced countries anytime soon. , Barry Eichengreen and Raul Razo-Garcia [source]

    Convergence of excitatory and inhibitory inputs onto CCK-containing basket cells in the CA1 area of the rat hippocampus

    EUROPEAN JOURNAL OF NEUROSCIENCE, Issue 5 2004
    Ferenc Mátyás
    Abstract The number and distribution of excitatory and inhibitory inputs affect the integrative properties of neurons. These parameters have been studied recently for several hippocampal neuron populations. Besides parvalbumin- (PV) containing cells that include basket and axo-axonic cells, cholecystokinin (CCK)-containing interneurons also form a basket cell population with several properties distinct from PV cells. Here, at the light microscopic level, we reconstructed the entire dendritic tree of CCK-immunoreactive (IR) basket cells to describe their geometry, the total length and laminar distribution of their dendrites. This was followed by an electron microscopic analysis of serial ultrathin sections immunostained against ,-aminobutyric acid, to estimate the density of excitatory and inhibitory synapses on their somata, axon initial segments and different subclasses of dendrites. The dendritic tree of CCK-IR basket cells has an average length of 6300 µm and penetrates all layers. At the electron microscopic level, CCK basket cells receive dendritic inputs with a density of 80,230 per 100 µm. The ratio of inhibitory inputs is relatively high (35%) and increases towards the soma (83%). The total numbers of excitatory and inhibitory synapses converging onto CCK-IR cells are ,,8200. Comparison of the two, neurochemically distinct basket cells reveals that CCK-containing basket cells receive much less synaptic input than PV cells; however, the relative weight of inhibition is higher on CCK cells. Additional differences in their anatomical and physiological properties predict that CCK basket cells are under a more diverse, elaborate control than PV basket cells, and thus the function of the two populations must be different.

    Analysis of the function of GABAB receptors on inhibitory afferent neurons of Purkinje cells in the cerebellar cortex of the rat

    EUROPEAN JOURNAL OF NEUROSCIENCE, Issue 10 2002
    Marta Than
    Abstract Purkinje cells, the output neurons of the cerebellar cortex, receive inhibitory input from basket, stellate and neighbouring Purkinje cells. The aim of the present study was to clarify the role of GABAB receptors on neurons giving inhibitory input to Purkinje cells. In sagittal slices prepared from the cerebellar vermis of the rat, the GABAB receptor agonist baclofen lowered the frequency and amplitude of spontaneous inhibitory postsynaptic currents (IPSCs) recorded in Purkinje cells. These effects were prevented by the GABAB receptor antagonist CGP 55845. Two mechanisms were involved in the depression of the inhibitory input to Purkinje cells. The first mechanism was suppression of the firing of basket, stellate and Purkinje cells. The second mechanism was presynaptic inhibition of GABA release from terminals of the afferent axons. This was indicated by the finding that baclofen decreased the amplitude of IPSCs occurring in Purkinje cells synchronously with action potentials recorded in basket cells. A further support for the presynaptic inhibition is the observation that baclofen decreased the amplitude of autoreceptor currents which are due to activation of GABAA autoreceptors at axon terminals of basket cells by synaptically released GABA. The presynaptic inhibition was partly due to direct inhibition of the vesicular release mechanism, because baclofen lowered the frequency of miniature IPSCs recorded in Purkinje cells in the presence of cadmium and in the presence of tetrodotoxin plus ionomycin. The results show that activation of GABAB receptors decreased GABAA receptor-mediated synaptic input to cerebellar Purkinje cells both by lowering the firing rate of the inhibitory input neurons and by inhibiting GABA release from their axon terminals with a presynaptic mechanism.

    International Portfolio Investment: Theory, Evidence, and Institutional Framework

    FINANCIAL MARKETS, INSTITUTIONS & INSTRUMENTS, Issue 3 2001
    Söhnke M. Bartram
    At first sight, the idea of investing internationally seems exciting and full of promise because of the many benefits of international portfolio investment. By investing in foreign securities, investors can participate in the growth of other countries, hedge their consumption basket against exchange rate risk, realize diversification effects and take advantage of market segmentation on a global scale. Even though these advantages might appear attractive, the risks of and constraints for international portfolio investment must not be overlooked. In an international context, financial investments are not only subject to currency risk and political risk, but there are many institutional constraints and barriers, significant among them a host of tax issues. These constraints, while being reduced by technology and policy, support the case for internationally segmented securities markets, with concomitant benefits for those who manage to overcome the barriers in an effective manner.

    Transcription factor NF-Y is involved in regulation of the JNK pathway during Drosophila thorax development

    GENES TO CELLS, Issue 2 2008
    Yasuhide Yoshioka
    The CCAAT motif-binding factor, nuclear factor Y (NF-Y) consists of three different subunits, NF-YA, NF-YB and NF-YC. Knockdown of Drosophila NF-YA (dNF-YA) in the notum compartment of wing discs by a pannir -GAL4 and UAS- dNF-YAIR mainly resulted in a thorax disclosed phenotype. Reduction of the Drosophila c-Jun N-terminal kinase (JNK) basket (bsk) gene dose enhanced the knockdown of dNF-YA-induced phenotype. Monitoring of JNK activity in the wing disc by LacZ expression in a puckered (puc) -LacZ enhancer trap line revealed reduction in the level of the JNK reporter, puc-LacZ signals, in dNF-YA RNAi clones. In addition, expression of wild-type Bsk effectively suppressed the phenotype induced by knockdown of dNF-YA. The bsk gene promoter contains a CCAAT motif and this motif plays a positive role in the promoter activity. We performed chromatin immunoprecipitation (ChIP) assays in S2 cells with anti-dNF-YA IgG and quantitative real-time PCR. The bsk gene promoter region containing the CCAAT boxes was effectively amplified in the immunoprecipitates by PCR. However, this region was not amplified in the immunoprecipitates from dNF-YA knockdown cells. Furthermore, the level of endogenous bsk mRNA is reduced in the dNF-YA knockdown larvae. These results suggest that dNF-Y is necessary for proper bsk expression and activity of JNK pathway during thorax development. [source]


    What should be given a priority , costly medications for relatively few people or inexpensive ones for many?

    HEALTH EXPECTATIONS, Issue 2 2008
    The Health Parliament public consultation initiative in Israel
    Abstract Background, In the past two decades, government and civic organizations have been implementing a wide range of deliberative public consultations on health care-related policy. Drawing on these experiences, a public consultation initiative in Israel called the Health Parliament was established. Goals, To implement a public consultation initiative that will engage members of the public in the discussion of four healthcare policy questions associated with equity in health services and on priorities for determining which medications and treatments should be included in the basket of national health services. Method, One hundred thirty-two participants from the general population recruited through a random sample were provided with background materials and met over several months in six regional sites. Dilemma activities were used and consultants were available for questions and clarifications. Participants presented their recommendations in a national assembly to the Minister of Health. Outcomes, Across the regional groups the recommendations were mostly compatible, in particular regarding considering the healthcare system's monetary state, even at the expense of equity, but for each policy question minority views were also expressed. A strong emphasis in the recommendations was pragmatism. Conclusion, Participants felt the experience was worthwhile; though the actual impact of their recommendations on policy making was indirect, they were willing to participate in future consultations. However, despite enthusiasm the initiative was not continued. Issues raised are whether consultation initiatives must have a direct impact on healthcare policy decisions or can be mainly a venue to involve citizens in the deliberation of healthcare policy issues.

    About Darcy's law in non-Galilean frame

    INTERNATIONAL JOURNAL FOR NUMERICAL AND ANALYTICAL METHODS IN GEOMECHANICS, Issue 3 2004
    C. Geindreau
    Abstract This paper is aimed towards investigating the filtration law of an incompressible viscous Newtonian fluid through a rigid non-inertial porous medium (e.g. a porous medium placed in a centrifuge basket). The filtration law is obtained by upscaling the flow equations at the pore scale. The upscaling technique is the homogenization method of multiple scale expansions which rigorously gives the macroscopic behaviour and the effective properties without any prerequisite on the form of the macroscopic equations. The derived filtration law is similar to Darcy's law, but the tensor of permeability presents the following remarkable properties: it depends upon the angular velocity of the porous matrix, it verifies Hall,Onsager's relationship and it is a non-symmetric tensor. We thus deduce that, under rotation, an isotropic porous medium leads to a non-isotropic effective permeability. In this paper, we present the results of numerical simulations of the flow through rotating porous media. This allows us to highlight the deviations of the flow due to Coriolis effects at both the microscopic scale (i.e. the pore scale), and the macroscopic scale (i.e. the sample scale). The above results confirm that for an isotropic medium, phenomenological laws already proposed in the literature fails at reproducing three-dimensional Coriolis effects in all types of pores geometry. We show that Coriolis effects may lead to significant variations of the permeability measured during centrifuge tests when the inverse Ekman number Ek,1 is ,,(1). These variations are estimated to be less than 5% if Ek,1<0.2, which is the case of classical geotechnical centrifuge tests. We finally conclude by showing that available experimental data from tests carried out in centrifuges are not sufficient to determining the effective tensor of permeability of rotating porous media.

    Nostalgia and giving to charity: a conceptual framework for discussion and research

    INTERNATIONAL JOURNAL OF NONPROFIT & VOLUNTARY SECTOR MARKETING, Issue 1 2008
    Altaf Merchant
    Academic work involving nostalgia has shown it to evoke a basket of emotions. This paper proposes a conceptual model that links nostalgia to charitable giving. We argue that the nostalgia evoked by certain NPOs (not-for-profit organizations) is likely to have a bearing on both emotional and familial utility derived by the donor. This in turn is likely to drive the donor commitment to the NPO. Thus by evoking nostalgia, certain NPOs are likely to emotionally engage their current and potential donors, which could facilitate the creation of long-term intimate relationships between them and their donors. However, the extent to which the NPO can evoke nostalgia is likely to depend upon the nostalgia proneness of the donor, the emotional importance of the past experiences evoked by the NPO, and the characteristics of the NPO such as the extent to which the NPO can alleviate the feelings of alienation, discontinuity, and the need for authenticity experienced by the donor. The paper provides a series of research propositions and proposes a research agenda. Copyright © 2007 John Wiley & Sons, Ltd. [source]


    Transvenous Parasympathetic Nerve Stimulation in the Inferior Vena Cava and Atrioventricular Conduction

    JOURNAL OF CARDIOVASCULAR ELECTROPHYSIOLOGY, Issue 1 2000
    PATRICK SCHAUERTE M.D.
    Parasympathetic Stimulation in the Inferior Vena Cava. Introduction: In previous reports, we demonstrated a technique for parasympathetic nerve stimulation (PNS) within the superior vena cava, pulmonary artery, and coronary sinus to control rapid ventricular rates during atrial fibrillation (AF). In this report, we describe another vascular site, the inferior vena cava (IVC), at which negative dromotropic effects during AF could consistently he obtained. Moreover, stimulation at this site also induced dual AV nodal electrophysiology. Methods and Results: PNS was performed in ten dogs using rectangular stimuli (0.1 msec/20 Hz) delivered through a catheter with an expandable electrode basket at its tip. Within 3 minutes and without using fluoroscopy, the catheter was positioned at an effective PNS site in the IVC at the junction of the right atrium. AF was induced and maintained by rapid atrial pacing. During stepwise increase of the PNS voltage from 2 to 34 V, a graded response of ventricular rate slowing during AF was observed (266 ± 79 msec without PNS vs 1,539 ± 2,460 msec with PNS at 34 V; P = 0.005 by analysis of variance), which was abolished by atropine and blunted by hexamethonium. In three animals, PNS was performed during sinus rhythm. Dual AV nodal electrophysiology was present in 1 of 3 dogs in control, whereas with PNS, dual AV nodal electrophysiology was observed in all three dogs. PNS did not significantly change sinus rate or arterial blood pressure during ventricular pacing. Conclusion: Stable and consistent transvenous electrical stimulation of parasympathetic nerves innervating the AV node can be achieved in the IVC, a transvenous site that is rapidly and readily accessible. The proposed catheter approach for PNS can be used to control ventricular rate during AF in this animal model. [source]


    Randal Heeb Innovation and Vertical Integration in Complementary Markets

    JOURNAL OF ECONOMICS & MANAGEMENT STRATEGY, Issue 3 2003
    Randal Heeb
    This paper studies vertical integration by an essential-good monopolist into complementary markets. Unlike previous studies of complementary products, consumers are allowed to purchase some components of a complementary basket, but not others. Two different pricing strategies by the integrated firm may emerge. In mass-market equilibria, the price of the complement under integration is zero and it is given away with the essential good. Niche-market equilibria have more conventional pricing. This dichotomy is consistent with consumer software pricing. Integration enhances consumer and total surplus, unless it leads to exit by the higher-quality rival, in which case welfare is reduced. Exit is most likely when it is least damaging to consumer welfare. Integration reduces innovation by the rival firm. The effect on innovation by the integrated firm is ambiguous, but numerical computation of an extended model indicates that integration increases the innovation of the integrated firm and enhances welfare.

    The Value Relevance of Accounting Information during a Financial Crisis: Thailand and the 1997 Decline in the Value of the Baht

    JOURNAL OF INTERNATIONAL FINANCIAL MANAGEMENT & ACCOUNTING, Issue 2 2000
    Roger Graham
    This study addresses whether the financial turmoil surrounding the devaluation of the baht affected the value relevance of Thai accounting information. Our results suggest a decline in the value relevance of Thai book values and earnings following the devaluation. Prior to mid 1997 the Bank of Thailand pegged the value of the baht to a basket of currencies of which 80% was weighted to the US dollar. In response to pressure by currency speculators the bank abandoned its peg on July 2 1997 in favor of a managed float. The devaluation was followed by volatile exchange rates. The change in value relevance of accounting information after the devaluation may be attributable to the initial recognition of foreign exchange losses and the subsequent recognition of foreign exchange gains as exchange rates fell and then recovered.

    Kinetic modeling of the photocatalytic degradation of air-borne pollutants

    AICHE JOURNAL, Issue 5 2004
    H. Ibrahim
    Abstract The photocatalytic conversion of organic model pollutants (acetone, acetaldehyde, and isopropanol) in a novel Photo-CREC-Air unit is considered. This photocatalytic unit features: (1) external near-UV lamps placed in parabolic reflectors, (2) a basket supporting the irradiated glass mesh holding TiO2 loadings to achieve high photoconversion rates, and (3) a fluid flow pattern securing high gas velocities in the near-mesh region. Given the high quantum efficiencies observed in Photo-CREC-Air and, as a result, the high prospects for this novel design, rate equations and associated mechanistic formulations are investigated. With this goal, a Langmuir,Hinshelwood model, involving a one-site model pollutant mechanism, is considered. The associated kinetic parameters with the related statistical indicators are established, using least-square nonlinear regression. It is found that this model is adequate for describing the photodegradation of acetone on both Degussa P25 and Hombikat UV-100. It is also observed that the same type of reaction rate model is less adequate for the photodegradation of acetaldehyde and isopropanol, in particular, for predicting the formation of carbon dioxide. © 2004 American Institute of Chemical Engineers AIChE J 50: 1017,1027, 2004 [source]


    Comonotonic Approximations for Optimal Portfolio Selection Problems

    JOURNAL OF RISK AND INSURANCE, Issue 2 2005
    J. Dhaene
    We investigate multiperiod portfolio selection problems in a Black and Scholes type market where a basket of 1 riskfree and m risky securities are traded continuously. We look for the optimal allocation of wealth within the class of "constant mix" portfolios. First, we consider the portfolio selection problem of a decision maker who invests money at predetermined points in time in order to obtain a target capital at the end of the time period under consideration. A second problem concerns a decision maker who invests some amount of money (the initial wealth or provision) in order to be able to fullfil a series of future consumptions or payment obligations. Several optimality criteria and their interpretation within Yaari's dual theory of choice under risk are presented. For both selection problems, we propose accurate approximations based on the concept of comonotonicity, as studied in Dhaene et al. (2002 a,b). Our analytical approach avoids simulation, and hence reduces the computing effort drastically. [source]


    Trichophyton mentagrophytes of rabbit origin causing family incidence of kerion: an environmental study

    MYCOSES, Issue 5 2006
    P. Van Rooij
    Summary Our laboratory was contacted by a family living directly above a rabbit farm. Both their children had developed a kerion, in consequence of a misdiagnosed superficial mycosis. This study was designed to demonstrate a link between the two kerion cases and the environmental contamination. The degree of contamination was estimated and factors favourising the spread of infection were determined. Dermatophytes were isolated from various environmental sites using Rodac plates. For direct sampling of scalp and fur the brushing technique was used. The farm and home environment initially showed a severe contamination by Trichophyton mentagrophytes. At the farm, cages and surfaces covered with rabbit hair were strongly contaminated. As for the home environment, the dog's basket and clothes from the mother carried a large number of spores. Trichophyton mentagrophytes was identified as responsible agent for the children's kerions and the lesions of the rabbits. Mother, eldest child and dog seemed to be excellent carriers. Cleaning and disinfection measures resulted in a reduction of the overall contamination. The home environment was no longer a source of contamination. Nevertheless, on the farm a fair number of dermatophytes could still be isolated from the wire meshes and roof beams covered with fluff. [source]


    Trends in affordability of the Illawarra Healthy Food Basket 2000,2007

    NUTRITION & DIETETICS, Issue 1 2009
    Peter WILLIAMS
    Abstract Aims:, The Illawarra Healthy Food Basket was developed as one measure to monitor the affordability of healthy eating in Australia. It consists of 57 items selected to meet the nutritional requirements of a reference family of five. The basket was first costed in the Illawarra region of Australia in 2000 and again in 2001 and 2003. The present study aimed to repeat the costing of the basket in 2005 and 2007 and to assess the trends in affordability since 2000. Methods:, Costing was carried out in the same five suburbs as previous surveys, using a large supermarket, greengrocer and butcher from each. Comparison data included: welfare entitlements obtained from Centrelink, average weekly earnings and the consumer price index for food. Main outcome measures:, The average weekly cost of the Illawarra Healthy Food Basket in 2005 and 2007, and trends in the costs compared with changes in average weekly earning and welfare benefits for the reference family. Results:, The total cost of the Illawarra Healthy Food Basket in 2007 was $242.49, an increase of 20.4% since 2000, with the greatest increases in the prices of vegetables (55.7%) and fruit (46.7%). Fruits, vegetables and meat were cheaper at independent grocers and butchers than in supermarkets. The percentage of average weekly earning or welfare payments required to purchase the Illawarra Healthy Food Basket remained stable at slightly below 30%. Conclusion:, These results indicate that the affordability of healthy eating has remained relatively constant from 2000 to 2007, but the significant increases in fruit and vegetable prices might be making healthy food choices more difficult.

    Evaluation of sustainable packaging in the norwegian shopping basket 2001,2007

    PACKAGING TECHNOLOGY AND SCIENCE, Issue 3 2010
    Hanne Møller
    Abstract The main purpose of the Norwegian Shopping Basket Survey (referred to here as the Survey) is to document development in packaging optimization and generation of packaging waste in the Norwegian packaging sector over time. As the environmental and resource efficiency of packaging systems depends to a large extent on the prevention of product loss, material intensity of the packaging and closing of the material loops, these factors are important elements in the characterization of sustainability of packaging systems. In this project we calculate indicators for material intensity and material recycling, based on the European Union (EU) directive on packaging and packaging waste (EC 64/92) and the corresponding European Committee for Standardization (CEN)-standards EN 13427-13432. The survey consists of 22 product categories that have a significant economic contribution to the retail sector. In each product category the three products with the highest turnover (market leaders) and the three products with the most rapid increase in turnover each year (market winners) are chosen. The survey result shows that the weighted packaging material intensity for the market leaders has been reduced but that the net material intensity has been rather constant. Data for the market winners indicate a much larger variation throughout the period, which is expected because many of the products change from year to year. The numbers of packaging changes are counted. Market changes are found to be the most important factor affecting the differences in material intensity. Changes in the packaging system of the individual products are less important. Copyright © 2010 John Wiley & Sons, Ltd. [source]


    Collagen Fiber and Versican Distribution Within the Lamina Propria of Fetal Vocal Folds,

    THE LARYNGOSCOPE, Issue 2 2008
    Rogerio Borghi Buhler MD
    Abstract Objectives: To analyze the presence and distribution of collagen fibers and versican in human vocal fold lamina propria of fetal larynges. Study Design: Cross sectional analysis of cadaveric vocal folds of human fetuses. Methods: Seven fetal larynges obtained from 28- to 36-week-old fetuses were analyzed with the Picrosirius-polarization method, immunohistochemistry, and image analysis. Results: Collagen fibers within the lamina propria exhibited a monolaminar distribution pattern and spatial arrangement in "wicker basket." Versican distribution was larger in the superficial and intermediate layers when compared to the deep layer. Conclusion: Our findings suggest that collagen and versican distribution and arrangement within the lamina propria in the developing fetus are important for vocalization at birth. [source]


    What Should the Weights of the Three Major Currencies be in a Common Currency Basket in East Asia?,

    ASIAN ECONOMIC JOURNAL, Issue 1 2006

    F31; F33; F36; F42 We consider what type of regional common currency should be introduced in East Asia in the future. The common currency basket is, in itself, more desirable as an anchor currency. In this paper we define two types of currency basket and investigate the long-term sustainability of adopting a common currency basket in East Asia. From our empirical results, a larger weight (but less than 100 percent) for the US dollar in the common currency basket tends to make bilateral exchange rates among East Asian countries stable in the long run.

    Abstract Objective: To assess changes in the cost and availability of a standard basket of healthy food items (the Healthy Food Access Basket [HFAB]) in Queensland. Methods: Analysis of five cross-sectional surveys (1998, 2000, 2001, 2004 and 2006) describes changes over time. Eighty-nine stores in five remoteness categories were surveyed during May 2006. For the first time a sampling framework based on randomisation of towns throughout the state was applied and the survey was conducted by Queensland Treasury. Results: Compared with the costs in major cities, in 2006 the mean cost of the HFAB was $107.81 (24.2%) higher in very remote stores in Queensland, but $145.57 (32.6%) higher in stores more than 2,000 kilometres from Brisbane. Over six years the cost of the HFAB has increased by around 50% ($148.87) across Queensland and, where data was available, by more than the cost of less healthy alternatives. The Consumer Price Index for food in Brisbane increased by 32.5% over the same period. Conclusions and Implications: Australians, no matter where they live, need access to affordable, healthy food. Issues of food security in the face of rising food costs are of concern particularly in the current global economic downturn. There is an urgent need to nationally monitor, but also sustainably address the factors affecting the price of healthy foods, particularly for vulnerable groups who suffer a disproportionate burden of poor health.

    Food availability, cost disparity and improvement in relation to accessibility and remoteness in Queensland

    This study is the first to describe disparity and change in the food supply between metropolitan, rural and remote stores by Accessibility/Remoteness Index of Australia (ARIA)1 category. A total of 92 stores (97% response rate) within five aggregate ARIA categories participated throughout Queensland in 2000. There was a strong association between ARIA category and the cost of the basket of basic foods, with prices being significantly higher (20% and 31% respectively) in the ,remote' and ,very remote' categories than in the ,highly accessible' category. The association with ARIA was less marked for fruit and vegetables than for other food groups, but not for tobacco and take-away food items. Basic food items were less available in the more remote stores. Over the past two years, relative improvements in food prices have been seen in stores in the ,very remote' category, with observed increases less than the consumer price index (CPI) for food. Some factors which may have contributed to this improvement are discussed. [source]


    Developing a strategy to reduce the high morbidity of patients with long-term urinary catheters: the BioMed catheter research clinic

    OBJECTIVE To assess the idea of managing patients having problems with long-term catheterization (LTC, normally used when all other methods of bladder management have failed or are unsuitable) in a dedicated clinic, to present a prospective analysis of consecutive new patients attending between February 2002 and October 2006, and to establish the incidence of bladder stones in patients who have recurrent catheter encrustation and blockage. PATIENTS AND METHODS Patients treated with LTC are a large heterogeneous group, mainly consisting of elderly people who have chronic disabilities, and catheter-associated complications occur in > 70% of them. In all, 260 consecutive new patients having problems with LTC were assessed; the evaluation consisted of basic demographics, a detailed history, clinical examination, urine analysis and flexible cystoscopy (FC) via the catheterization route. Patients with bladder stones were screened with FC for recurrence of stones at 3, 6 and 12 months after treatment. RESULTS In all, 117 men and 143 women (mean age 67.7 years, range 23,97) were assessed; 147 (55.5%) had catheter encrustation. FC showed that 66 of the 147 patients (45%) had bladder stones. Forty-eight patients (73%) were successfully treated at the same clinic appointment and their stones were removed with the help of a tip-less stone basket. Eighteen patients (27%) were referred for inpatient treatment of bladder stones under general anaesthesia. Twenty of 66 patients with bladder stones (30%) formed recurrent bladder stones at a mean (range) follow-up of 8.1 (3,18 months). In addition, 36 patients had successful insertion of suprapubic catheter (SPC) under local anaesthetic in the clinic, and 11 were referred for SPC insertion under general anaesthesia. Two patients were diagnosed with bladder transitional cell carcinoma. CONCLUSION The introduction of a dedicated catheter clinic, equipped with facilities such as FC and a hoist, enables patients to be treated in an environment that meets their needs and potentially reduces the risk of more complex stone removal and catheter problems at a later date. It can also act as a potential source of data for use in research and development. A significant proportion (45%) of patients with catheter encrustation and blockage had formed bladder stones. Our study provides a rationale for FC of all such patients to detect and remove stones. [source]
