    Relative group size and minority school success: the role of intergroup friendship and discrimination experiences

    Get PDF
    From an intergroup relations perspective, relative group size is associated with the quantity and quality of intergroup contact: more positive contact (i.e., intergroup friendship) supports, and negative contact (i.e., experienced discrimination) hampers, minority identity, and school success. Accordingly, we examined intergroup contact as the process through which perceived relative proportions of minority and majority students in school affected minority success (i.e., school performance, satisfaction, and self-efficacy). Turkish minorities (N = 1,060) were compared in four Austrian and Belgian cities which differ in their typical school ethnic composition. Across cities, minority experiences of intergroup contact fully mediated the impact of perceived relative group size on school success. As expected, higher minority presence impaired school success through restricting intergroup friendship and increasing experienced discrimination. The association between minority presence and discrimination was curvilinear, however, so that schools where minority students predominated offered some protection from discrimination. To conclude, the comparative findings reveal positive and negative intergroup contact as key processes that jointly explain when and how higher proportions of minority students affect school success

    Effects of climate change on the dispersion of white grub damages in the Austrian grassland

    Recent changes in occurrence of agricultural pests in Austria might already reflect climate change phenomena. In this study, an inventory of white grub (Melolontha melolontha, Amphimallon solstitiale and Phyllopertha horticola) damages in Austrian grassland including organic cultivation was performed by questioning plant protection consultants of 74 Agricultural County Chambers. Altogether, a cumulated 14.800 hectares of white grub damages were recorded. From 2000 onwards, a steady increase of white grub damages occurred with a climax in the year of heat and drought 2003. The infested fields extended along the alpine main ridge from Vorarlberg up to the alpine foreland. Additionally, southern slopes of the Danube valley in Upper and Lower Austria were affected. Very likely, the damages were mainly due to the garden chafer P. horticola. From 2004 to 2006, the extent of damages decreased again all over Austria. By studying meteorological data, it became obvious that the damaged areas were mainly situated in regions with a strong precipitation deficit. On-farm investigations performed in 2007 strengthened the hypothesis that drought and elevated soil temperatures might be the decisive factors for a strong development of grub populations and subsequent feeding damages. Additionally, drought can increase the effects of grub damage by delaying the regeneration of the damaged sward. A strongly damaged sward on slopes can be dangerous for the farmers e.g. by slipping machines

    Visitor profiling for cable car mountain destinations as a basis for protected area management : a case study of the summer season in the Tatra Mountains at Kasprowy Wierch (Poland) and Skalnaté Pleso (Slovakia)

    Protected areas play a crucial role in the conservation of vulnerable mountain ecosystems, but at the same time they may serve as tourist destinations and attract large numbers of visitors. Areas located in close proximity to cable cars belong to some of the most challenging sites for mountain protected area management. This study focuses on two cable car areas: Kasprowy Wierch (Tatra National Park, Poland) and SkalnatĂ© Pleso (Tatra National Park, Slovakia). Both sites belong to the most heavily used leisure destinations in the Tatra Mountains. The study focused on the summer, snow-free tourist peak-season, for which there is an ongoing discussion concerning the development of cable car services. In 2014 and 2015, on-site interviews were conducted in the two study areas (n = 3 304). In order to better understand visitors’ needs and goals, visitor profiling using K-means clustering was performed. Four distinct segments based on visitor motivations were identified: nature oriented (32 %), family / friends & well-being oriented (23 %), sports oriented (14 %), and a mixed segment with multiple motivations (31 %). The results show that two tourist segments were not particularly interested in nature experience, although they visited protected areas. A significant relationship between motivational segments and trip characteristics was identified. The visitor segments defined can be used practically in the management of cable car destinations located within protected areas

    Local knowledge held by farmers in Eastern Tyrol (Austria) about the use of plants to maintain and improve animal health and welfare

    Background The sustainable management of animal health and welfare is of increasing importance to consumers and a key topic in the organic farming movement. Few systematic studies have been undertaken investigating farmers’ local knowledge related to this issue. Ethnoveterinary medicine (EVM) is a discipline focusing on local knowledge and folk methods in veterinary medicine, however most ethnoveterinarian studies primarily address the treatment of animal diseases. Very few studies have explored prophylactic methods. Methods An ethnoveterinary research project in Eastern Tyrol (Austria) was conducted in 2004 and 2005 to gather information about local knowledge of animal husbandry from 144 informants, with the emphasis on plants that maintain livestock health and welfare. Results Informants mentioned a total of 87 plants and 22 plant-based generic terms in the context of maintaining and improving livestock health and welfare. The most important preventive measures for maintaining and improving animal health and welfare were practices related to “fodder” and “feeding”. In this category the plants mentioned could be grouped according to three different perceptions about their effect on animals: “Good or bad fodder”, “Functional fodder” and “Fodder medicine”. In addition to fodder, environmental management, the human-animal relationship, household remedies and cultural/religious activities were also mentioned. When asked about practices in the past that maintained animal health and well-being, interviewees mentioned, for example, the importance of the diversity of sources that used to be available to obtain feed and fodder. Conclusions The informants’ approach that feeding is central to livestock welfare is in line with the standard scientific literature on animal health, including in organic farming. Various scientific studies into common fodder evaluate the nutritive and dietary value, efficiency and safety of fodder. Future studies also have to consider the evaluation of traditional, local fodder resources. In fact, the value of ‘food as medicine’ for humans in the context of local knowledge has been widely assessed, but the potential health benefits of fodder and nutraceuticals in local and traditional ethnoveterinary methods require further attention

    The Role of Multinational Corporations in Metropolitan Innovation Systems – Empirical Evidence from Europe and South-East Asia

    Get PDF
    Using firm-level survey data from Barcelona, Stockholm, Vienna in Europe and Singapore, Penang (Malaysia) and Bangkok in South-East Asia the paper enquires into the different R&D and innovation behaviour of multinational and local companies in these Metropolitan Regions. Scrutinizing a set of input, throughput and output indicators as well as information on cooperation characteristics, we try to evaluate a) if the spatial pattern of more (intense) innovation activity in Europe when compared to South-East Asia is still valid; and b) if there are reasons to believe that R&D units of multinational corporations in Europe are mainly concerned with the enhancement of the knowledge base and the development of future competitiveness by tapping into localized knowledge and using the particular host regions’ innovation systems, while, on the other hand, MNCs in South-East Asia use R&D to support existing production facilities in order to exploit an existing competitive advantage. We are able to show that there is still a major gap in the innovation performance between South-East Asia and Europe and that there are indeed indications that R&D units in Europe are more orientated towards the augmentation of the company’s knowledge base.

    The relationship between religion and fertility: Evidence from Austria

    Get PDF
    Data from the Austrian Family and Fertility Survey are used to examine for the first time the contemporary relationship between religion and fertility in first unions in Austria. Although Austria is a Catholic country, results from a Poisson hurdle model show that both women s denominational affiliation and religiosity affect the number of children born. Unions religious composition does not result in clear evidence. There furthermore is mainly no effect of religion on the timing of births. There however is a puzzle: Females and unions of other than Catholic or no religious affiliation have a higher transition rate to third birth.Religion, fertility, count data, Poisson hurdle model, Austria

    Determinants of response to a parent questionnaire about development and behaviour in 3 year olds: European multicentre study of congenital toxoplasmosis.

    Get PDF
    Background: We aimed to determine how response to a parent-completed postal questionnaire measuring development, behaviour, impairment, and parental concerns and anxiety, varies in different European centres. Methods: Prospective cohort study of 3 year old children, with and without congenital toxoplasmosis, who were identified by prenatal or neonatal screening for toxoplasmosis in 11 centres in 7 countries. Parents were mailed a questionnaire that comprised all or part of existing validated tools. We determined the effect of characteristics of the centre and child on response, age at questionnaire completion, and response to child drawing tasks. Results: The questionnaire took 21 minutes to complete on average. 67% (714/1058) of parents responded. Few parents (60/1058) refused to participate. The strongest determinants of response were the score for organisational attributes of the study centre (such as direct involvement in follow up and access to an address register), and infection with congenital toxoplasmosis. Age at completion was associated with study centre, presence of neurological abnormalities in early infancy, and duration of prenatal treatment. Completion rates for individual questions exceeded 92% except for child completed drawings of a man (70%), which were completed more by girls, older children, and in certain centres. Conclusion: Differences in response across European centres were predominantly related to the organisation of follow up and access to correct addresses. The questionnaire was acceptable in all six countries and offers a low cost tool for assessing development, behaviour, and parental concerns and anxiety, in multinational studies

    Estimating the Wage Curve with Spatial Effects and Spline Functions

    Get PDF
    In this paper, we provide new empirical evidence on the relationship between regional wages and unemployment using spatial econometric techniques and allowing for nonlinearities in the model. The estimates are based on Austrian administrative data for the year 2001. The wage elasticity with respect to the unemployment rate is about -0.03 and thus quite low in international comparison. This can be explained by institutional characteristics of the Austrian wage bargaining system. Allowing for a more flexible functional form by estimating a model with linear spline functions, we find that the wage curve is only present in areas with a medium level of unemployment. The often used quadratic specification is therefore inadequate in describing the shape of the earnings unemployment relationship. Finally, we show how OLS tends to overestimate the wage-curve elasticity in absolute terms.wage curve, unemployment, spatial dependence, spline functions

    Evaluating the Effects of Farm Programs: Results from Propensity Score Matching

    Get PDF
    The paper applies a non-parametric propensity score matching approach to evaluate the effects of two types of farm programs (agri-environment (AE) programs and the less favoured area (LFA) scheme) on input use and farm output of individual farms in Germany. The analysis reveals a positive and significant treatment effect of the LFA scheme for farm sales and the area under cultivation. Participants in AE schemes are found to significantly increase the area under cultivation (in particular grassland), resulting in a decrease of livestock densities. Furthermore, participation in AE programs significantly reduced the purchase of farm chemicals (fertilizer, pesticide). We also find substantial differences in the treatment effect between individual farms (heterogeneous treatment effects). Farms which can generate the largest benefit from the program are most likely to participate.evaluation, farm programs, propensity score matching, Agricultural and Food Policy,

    Pickup usability dominates: a brief history of mobile text entry research and adoption

    Get PDF
    Text entry on mobile devices (e.g. phones and PDAs) has been a research challenge since devices shrank below laptop size: mobile devices are simply too small to have a traditional full-size keyboard. There has been a profusion of research into text entry techniques for smaller keyboards and touch screens: some of which have become mainstream, while others have not lived up to early expectations. As the mobile phone industry moves to mainstream touch screen interaction we will review the range of input techniques for mobiles, together with evaluations that have taken place to assess their validity: from theoretical modelling through to formal usability experiments. We also report initial results on iPhone text entry speed
