School Milk Consumption in Germany - What are Important Product Attributes for Children and Parents?

Food Consumption/Nutrition/Food Safety,

Driving factors for school milk demand in Germany

School milk consumption has declined steadily in Germany. A research project was set up to retrieve quantifiable information on the different factors of influence and to develop solutions to improve the school milk consumption.. The main goal is to evaluate the impact of price, product range, distribution form, information campaigns, regional situation, county based social index, socially-funded school milk distribution, and gender shares, as well as the immigration background share within a class. A total of 400 primary schools were selected by stratified random sampling. Surveys for principals and school milk managers were used to gain information on distribution problems throughout the milk chain, on the handling, and their attitudes towards school milk and milk in general. The price of school milk is being reduced stepwise in the 2008/09 school year. The quantity of consumption is reported per class. A multilevel analysis is applied to determine the factors driving consumption at the class level. First results will be validated. The paper comprises an extended introduction, followed by the research approach. A descriptive analysis is given following a detailed description of the experiment.. The estimation procedure is discussed before the results are presented. Finally, a qualification of outcomes and conclusions concerning further research are found.School Milk, Demand Subsidy, Food Demand, Multilevel Analysis., Agricultural and Food Policy, Food Consumption/Nutrition/Food Safety,

EINE LOGIT-ANALYSE ZUR DIFFERENZIERUNG VON KÄUFERN UND NICHT-KÄUFERN VON SCHULMILCH IN DEUTSCHLAND

Vor dem Hintergrund eines sinkenden Schulmilchkonsums in Deutschland stellt sich generell die Frage, welche Faktoren für die Kaufentscheidung von Schulmilch wichtig sind und, ob unterschiedliche Konsummuster für einzelne Gruppen existieren. Dieser Beitrag erweitert bestehende ökonometrische Erklärungsansätze um Schüler- und Haushaltscharakteristika. Dazu werden auf der Grundlage der Discrete Choice-Theorie zwei Konsummuster, die Gruppe der Schulmilchbesteller und die Gruppe der Nicht-Besteller, betrachtet. Mit Hilfe eines Logit-Modells werden Einflussfaktoren analysiert, die über das Konsummuster entscheiden. Als wichtige Faktoren kristallisieren sich die befürwortenden und ablehnenden Einstellungen der Schulkinder und ihrer Eltern gegenüber Milch und Schulmilch heraus. Weiterhin variiert die Chance Schulmilch zu bestellen mit dem Geschlecht, dem Alter und dem Migrationshintergrund der Schulkinder. Schulkinder aus Haushalten mit niedrigen Nettoeinkommen weisen eine höhere Chance auf, keine Schulmilch zu bestellen als Kinder aus Haushalten mit höherem Einkommen. Das Produktsortiment beeinflusst ebenfalls die Bestellwahrscheinlichkeit. Ist dieses vielfältig, erhöht sie sich, werden hingegen auch andere Getränke angeboten, sinkt sie. School milk consumption is currently declining in Germany. To analyse the reasons for this development existing econometric models are extended by characteristics of pupils and their households. Based on discrete choice theory, a logit model is applied investigating factors which distinguish school milk buyers from non-buyers. Important factors are the attitude of pupils and children towards milk and school milk as well as nutritional behavior at school. Buying behavior varies with age, sex and the migration background of pupils. Girls, pupils with migration background and older pupils show a higher chance of being in the non-buyer group. The same holds for children who belong to a low-income household. At school a higher variety of school milk products increases the chance for buying school milk while offering non-milk beverages reduces it.Schulmilch, Logit-Modell, Nachfrageanalyse, school milk, logit model, demand analysis, Agribusiness,

The Upper Respiratory Tract as a Microbial Source for Pulmonary Infections in Cystic Fibrosis. Parallels from Island Biogeography

A continuously mixed series of microbial communities inhabits various points of the respiratory tract, with community composition determined by distance from colonization sources, colonization rates, and extinction rates. Ecology and evolution theory developed in the context of biogeography is relevant to clinical microbiology and could reframe the interpretation of recent studies comparing communities from lung explant samples, sputum samples, and oropharyngeal swabs. We propose an island biogeography model of the microbial communities inhabiting different niches in human airways. Island biogeography as applied to communities separated by time and space is a useful parallel for exploring microbial colonization of healthy and diseased lungs, with the potential to inform our understanding of microbial community dynamics and the relevance of microbes detected in different sample types. In this perspective, we focus on the intermixed microbial communities inhabiting different regions of the airways of patients with cystic fibrosis

Evaluation Research and Institutional Pressures: Challenges in Public-Nonprofit Contracting

This article examines the connection between program evaluation research and decision-making by public managers. Drawing on neo-institutional theory, a framework is presented for diagnosing the pressures and conditions that lead alternatively toward or away the rational use of evaluation research. Three cases of public-nonprofit contracting for the delivery of major programs are presented to clarify the way coercive, mimetic, and normative pressures interfere with a sound connection being made between research and implementation. The article concludes by considering how public managers can respond to the isomorphic pressures in their environment that make it hard to act on data relating to program performance.This publication is Hauser Center Working Paper No. 23.

Many Labs 5:Testing pre-data collection peer review as an intervention to increase replicability

Replication studies in psychological science sometimes fail to reproduce prior findings. If these studies use methods that are unfaithful to the original study or ineffective in eliciting the phenomenon of interest, then a failure to replicate may be a failure of the protocol rather than a challenge to the original finding. Formal pre-data-collection peer review by experts may address shortcomings and increase replicability rates. We selected 10 replication studies from the Reproducibility Project: Psychology (RP:P; Open Science Collaboration, 2015) for which the original authors had expressed concerns about the replication designs before data collection; only one of these studies had yielded a statistically significant effect (p < .05). Commenters suggested that lack of adherence to expert review and low-powered tests were the reasons that most of these RP:P studies failed to replicate the original effects. We revised the replication protocols and received formal peer review prior to conducting new replication studies. We administered the RP:P and revised protocols in multiple laboratories (median number of laboratories per original study = 6.5, range = 3?9; median total sample = 1,279.5, range = 276?3,512) for high-powered tests of each original finding with both protocols. Overall, following the preregistered analysis plan, we found that the revised protocols produced effect sizes similar to those of the RP:P protocols (?r = .002 or .014, depending on analytic approach). The median effect size for the revised protocols (r = .05) was similar to that of the RP:P protocols (r = .04) and the original RP:P replications (r = .11), and smaller than that of the original studies (r = .37). Analysis of the cumulative evidence across the original studies and the corresponding three replication attempts provided very precise estimates of the 10 tested effects and indicated that their effect sizes (median r = .07, range = .00?.15) were 78% smaller, on average, than the original effect sizes (median r = .37, range = .19?.50)

Review of Kaon Physics at CERN and in Europe

The Kaon physics program at CERN and in Europe will be presented. I will first give a short review of recent results form the NA48/2 and NA62 experiments, with special emphasis to the measurement of RK , the ratio of Kaon leptonic decays rates, K → eν and K → μν, using the full minimum bias data sample collected in 2007-2008. The main subject of the talk will be the study of the highly suppressed decay K → πνν. While its rate can be predicted with minimal theoretical uncertainty in the Standard Model (BR ∼ 8 × 10−11), the smallness of BR and the challenging experimental signature make it very difficult to measure. The branching ratio for this decay is thus a sensitive probe of the flavour sector of the SM. The aim of NA62 is the measurement of the K → πνν BR with ∼ 10% precision in two years of data taking. This will require the observation of 10K decays in the experiment's fiducial volume, as well as the use of high-performance systems for precision tracking, particle identification, and photon vetoing. These aspects of the experiment will also allow NA62 to carry out a rich program of searches for lepton flavour and/or number violating K decays. Data taking will start in October 2014. The physics prospects and the status of the construction and commissioning of the NA62 experiment will be presented. In the last part of the talk I will report on Kaon physics results and prospects from other experiments at CERN (e.g. LHCb) and in Europe (e.g. KLOE and KLOE-2) and briefly mention the status in US
