The Relationship between Supply Chain Coordination and Quality Assurance Systems: A Case Study Approach on the German Meat Sector

The German meat industry faces a high demand for food safety and traceability. After several meat scandals in the recent past, efforts have to be made to regain consumer trust and to assure access to export markets. Apart from a few niche markets, there is no focal company in the German pork supply chain which efficiently coordinates food chain information, harmonizes the multiplicity of different IT systems or takes on professional public relations in charge of the whole sector. In cases of food crises, essential up- and downstream information slowly flows across the supply chain which hinders both seamless traceability and the harmonization of production processes between the various stages of the supply chain. This contribution focuses on the opportunities for more efficient coordination based on spot market environments. With reference to the theory of organization economics, a case study of the QS Qualität und Sicherheit GmbH as the leading certification scheme that addresses the German meat industry was carried out. Several non-classical certification activities which fall within the scope of coordination were identified with QS. Based on the assumption that the company continuously improves the coordination of the supply chain, there are opportunities for the meat sector as a whole which are pointed out in the conclusion.Agribusiness, Agricultural and Food Policy, Farm Management, Food Consumption/Nutrition/Food Safety,

Chronological relationship between antisocial personality disorder and alcohol dependence

Personality disorders, and particularly antisocial personality disorder (ASPD), frequently co-occur with alcohol dependence. ASPD is considered to be an important cofactor in the pathogenesis and clinical course of alcohol dependence. The chronological relationship between the onset of symptoms of ASPD and alcohol-dependence characteristics has not yet been studied in great detail and the role of ASID in classification schemes of alcohol dependence as suggested by Cloninger and Schuckit has yet to be determined. We studied 55 alcohol-dependent patients to assess the prevalence and age at manifestation of ASPD, conduct disorder characteristics as well as alcohol dependence by employing the Semi-Structured Assessment for the Genetics of Alcoholism and the Structured Clinical Interview for DSM-IIIR. Results indicate that the onset of ASPD characteristics precede that of alcohol dependence by some 4 years. This finding suggests that in patients with ASPD, alcohol dependence might be a secondary syndrome as suggested by previous research. Copyright (C) 2002 S. Karger AG, Basel

MercyOne: Patient Advocate

MercyOne Sartori Hospital Kaitlyn Bahlmann For my cooperative education internship, I decided to volunteer as a patient advocate on the medical/surgical floor of Sartori Hospital in Cedar Falls. My poster will describe my experience interacting with and helping surgical patients have a better hospital stay. It’ll explain the purpose of volunteers and the psychological benefits that they provide for patients and their families. Volunteering at the hospital has given me direct patient contact experience and supplemented my other healthcare experiences as a pre-physician’s assistant student

Impulsive traits and 5-HT2A receptor promoter polymorphism in alcohol dependents: Possible association but no influence of personality disorders

Objective: Impulsive behavior in alcoholics puts them at serious risk of severer course of disease and has been related to the serotonergic neurotransmission dysfunction. The aim of this study is to investigate the association between impulsive aggression in alcohol dependents with regard to the G-1438A polymorphism in the promoter region of the 5-HT2A receptor gene. Furthermore, we investigated the statistical interaction between 5-HT2A alleles, antisocial personality disorder (APD) and impulsive aggression in alcohol dependents. Alcohol dependents were investigated because these personality disorders and impulsive behavior are very frequent in alcohol dependence anf of clinical relevance. Methods: One hundred and thirty-five patients of German descent meeting DSM-IV criteria of alcohol dependence were recruited. Blood samples were taken from alcohol dependents to determine 5-HT2A promoter polymorphisms using PCR (polymerase chain reaction) of lymphocyte DNA. Impulsive aggression was assessed using a German version of the Barratt Impulsiveness Scale which was translated and backtranslated. Alcohol dependents were subdivided into low- or high-impulsivity groups using a median split of the Barratt score. APD and borderline personality disorder (BPD) were assessed using the SCID-II interview. Results: The low-impulsivity group was slightly older and showed a later age at alcoholism onset than the highly impulsive group. Alcohol dependents with high impulsive traits showed a significant association with 5-HT2A 1438 A alleles. After excluding alcohol dependents with APD or BPD from the analysis, this association remained significant. Furthermore, no association between APD, BPD and 5-HT2A alleles was noted. Conclusions: Inpatient alcohol dependents showed a significant association between 5-HT2A A alleles and impulsive traits, independent of the presence of APD or BPD. No association was noted between personality disorders and the polymorphism. This is the first report about an association of 5-HT2A promoter polymorphism and impulsive behavior in alcohol dependents. This finding may refer only to impulsive traits and may be independent of personality disorders in this sample. These results have to be confirmed in larger samples and in healthy control subjects to determine whether this association is of general validity. Copyright (C) 2001 S. Karger AG, Basel

Structure and mobility in highly viscous silicate solutions

This thesis is concerned with the investigation of highly condensed, highly viscous silicate systems by means of NMR methods (mainly 29si-NMR investigations). The work focused on silicate solutions containing colloidal particles in sol and gel form with the interest of the work centred on the systems near the sol/gel-transition. Quantitative information about the behaviour of silicate species in these silicate systems is presented and some information about die role of protons and sodium cations in the silicate solutions is provided The structure of the colloidal material existing in these highly condensed silicate systems is investigated along with the behaviour of colloidal particles in several situations such as decreasing alkalinity or changing Si02-concentration. Additionally an idea of the range of particle sizes in the colloidal material in highly-condensed silicate solutions has been obtained. The dynamics of the silicate systems were studied in terms of rotational mobility as well as diffusive motion. Exchange processes between silicate species were monitored using ID-exchange spectroscopy. An investigation of the influence of additives, in particular surfactants, on highly condensed silicate systems was carried out by adding representative surfactants of the categories cationic, anionic and non-ionic

Nonreciprocal Bloch Oscillations in Magneto-Optic Waveguide Arrays

We show that nonreciprocal optical Bloch-like oscillations can emerge in transversely magnetized waveguide arrays in the presence of an effective index step between the waveguides. Normal modes of the system are shown to acquire different wavenumbers in opposite propagation directions. Significant differences in phase coherence and decoherence between these normal modes are presented and discussed. Non-reciprocity is established by imposing unequal vertical refractive index gradients at the substrate/core, and core/cover interfaces in the presence of transverse magnetization.Comment: 12 pages, 2 figure

Tidal controls on trace gas dynamics in a seagrass meadow of the Ria Formosa lagoon (southern Portugal)

Coastal zones are important source regions for a variety of trace gases, including halocarbons and sulfur-bearing species. While salt marshes, macroalgae and phyto-plankton communities have been intensively studied, little is known about trace gas fluxes in seagrass meadows. Here we report results of a newly developed dynamic flux chamber system that can be deployed in intertidal areas over full tidal cycles allowing for highly time-resolved measurements. The fluxes of CO2, methane (CH4) and a range of volatile organic compounds (VOCs) showed a complex dynamic mediated by tide and light. In contrast to most previous studies, our data indicate significantly enhanced fluxes during tidal immersion relative to periods of air exposure. Short emission peaks occurred with onset of the feeder current at the sampling site. We suggest an overall strong effect of advective transport processes to explain the elevated fluxes during tidal immersion. Many emission estimates from tidally influenced coastal areas still rely on measurements carried out during low tide only. Hence, our results may have significant implications for budgeting trace gases in coastal areas. This dynamic flux chamber system provides intensive time series data of community respiration (at night) and net community production (during the day) of shallow coastal systems.German Federal Ministry of Education and Research (BMBF) [03F0611E, 03F0662E]; EU FP7 ASSEMBLE research infrastructure initiative
