Entwicklung präventiver Tiergesundheitskonzepte bei kleinen Wiederkäuern im ökologischen Landbau
Die Ergebnisse gelten für ökologische und konventionelle Betriebe. Sehr problematisch ist die regional mangelhafte Verfügbarkeit spezialisierter Tierärzte/Berater.
Endoparasiten: Durch Prophylaxe, gezielte Diagnostik und restriktiven Arzneimitteleinsatz kann ein tolerabler Parasitendruck hergestellt und der Entwicklung von Anthelmintikaresistenz entgegengesteuert werden. Einzeltier- oder Teilherdenbehandlung sollte die Routinebehandlung der Gesamtherde ersetzen. Die überwiegende Stallhaltung mit befestigtem Auslauf ist in Problembetrieben sinnvoll. Ein Herdengesundheitsplan und die Züchtung auf Resistenz ist wünschenswert. Alternative Behandlungsverfahren können derzeit nicht empfohlen werden.
Infektionskrankheiten: Basale Präventionsmaßname ist die routinemäßige Bestandsdokumentation sowie die Untersuchung von verendeten Tieren/Kümmerern (ab 5%). Freiwillige, modulare Hygieneprogramme werden von Tierhaltern gegenüber bindenden Leitlinien bevorzugt. Notwendig ist eine erleichterte Impfstoffeinfuhr und -anwendung aus dem EU-Ausland. Homöopathie ist zur Entwurmung ungeeignet, indikationsbedingt zur Stärkung der Immunabwehr evt. sinnvoll. Positiver Nebeneffekt der Homöopathikagabe sind verbesserte Tierbeobachtung und spezielleres Management. Neu wird zukünftig vor allem die Übertragung der Verantwortung für die Sicherstellung der Lebensmittelqualität auf den Erzeuger sein.
Spurenelemente: Mineralfuttereinsatz ist auch im Ökolandbau notwendig. Kompensationsmöglichkeiten über selektive Pflanzen- oder Laubfütterung/ -düngung sind gering. Für Ziegen sind die Gehalte fast aller Futterpflanzen zu gering. Futtermittel- sowie Blut- und Organanalysen sollten zur Objektivierung der Bestandssituation vermehrt erhoben werden. Zunehmender Verlust an Biodiversität trägt maßgeblich zur Verarmung der Futtermittel bei. In der Diagnostik, auf dem Gebiet der Referenzwerte sowie bezüglich der örtlich zu erwartenden Spurenelemente in Futterpflanzen besteht dringender Forschungsbedarf
Integrity Testing of Gas Permeable Silicone Filters
This report investigates the most reasonable, cost efficient, and reliable ways to integrity test a filter made from a permeable silicone membrane for future biomedical and pharmaceutical applications. The goal of the project was to create a fixture that a pharmaceutical company can use to quickly and reliably test the integrity of the filter. A variety of methods are outlined to test the integrity of the filter, after a series of quantitative tests, a single method was established that meet the requirements most thoroughly. The method that was determined to be most effective involves a series of components including a flow meter and pressure regulator to demonstrate the Flow Meter Test . Following a strict schedule and close communication and mentoring from Dr. Lazzara, a reliable way for medical professionals to test the integrity of the filters was determined and is outlined in this report
Anxiety about Digital Security and Terrorism and Support for Counter-terror Measures
Purpose: This paper aims to determine the potential predictors of anxiety about digital security, terrorist threats and support for high-tech counter measures.
Design/methodology/approach: In Study 1, 195 participants indicated their anxiety about digital security systems, data protection and social networking sites. In Study 2, 107 participants indicated their anxiety about domestic terrorism, international terrorism and extremist groups. In Study 3, 261 participants indicated their support for high-tech counter terrorism measures.
Findings: Study 1 suggests that whereas anxiety about digital security systems, data protection and social networking sites were positively predicted by right-wing authoritarianism, anxiety about social networking was also negatively predicted by time spent online. Study 2 shows that time spent online was a negative predictor of anxiety about domestic terrorism. Study 3 indicates that the strongest positive predictor of support for all the measures was right-wing authoritarianism, followed by national identity.
Research implications: The findings show the relevance of terror management theory to digital security and counter-terrorism.
Practical implications: It appears that right-wing authoritarianism and national identity may serve as mechanisms for people to subjectively counter the presented threats. This notion may inform relevant policy and practice aimed at making communities safer and potentially help introduce counter-terror measures with less public backlash.
Social implications: When designing counter-terror measures, policy makers should consider compound national identities (e.g., Catalan or Basque people).
Originality/Value: The paper makes contribution to underexplored areas of terrorism anxiety and support for counter-terror measures
Task-Based Noise Exposures for Farmers Involved in Grain Production
Few studies have been done examining noise exposures associated with agricultural tasks. This study was conducted to address that research gap by calculating the noise exposures for tasks and equipment associated with grain production and assessing the variability in those exposures. An additional aim of this study was to identify tasks and equipment that could be targeted for intervention strategies as a means toward reducing the total noise exposures of farmers and farm workers. Through the use of personal noise dosimetry and direct observation, over 30,000 one-minute noise exposure measurements and corresponding task and equipment data were collected on 18 farms and compiled into a task-based noise exposure database. Mean noise exposures were calculated for 23 tasks and 18 pieces of equipment. The noise exposures for the tasks and equipment ranged from 78.6 to 99.9 dBA and from 80.8 to 96.2 dBA, respectively, with most of the noise exposures having a large standard deviation and maximum noise exposure level. Most of the variability in the task and equipment noise exposures was attributable to within-farm variations (e.g., work practices, distance from noise sources). Comparisons of the mean noise exposures for the agricultural tasks and equipment revealed that most were not statistically different. Grain production tasks and equipment with high mean noise exposures were identified. However the substantial variability in the noise exposures and the occurrence of intense noise measurements for nearly every task and piece of equipment indicate that targeting a few specific tasks or equipment for intervention strategies would reduce lifetime noise exposure but would not completely eliminate exposure to hazardous noise levels
Interoperability: maintaining clear superordinate goals, reducing task complexity, and optimizing team size to ensure inter-agency action implementation in critical incident decisions.
This study demonstrates how naturalistic decision-making (NDM) can be usefully applied to study ‘decision inertia’ – Namely the cognitive process associated with failures to execute action when a decision-maker struggles to choose between equally perceived aversive outcomes. Data assessed the response and recovery from a sudden impact disaster during a 2-day immersive simulated emergency response. Fourteen agencies (including police, fire, ambulance, and military) and 194 participants were involved in the exercise. By assessing the frequency, type, audience, and content of communications, and by reference to five subject matter experts’ slow time analyses of critical turning points during the incident, three barriers were identified as reducing multiagency information sharing and the macrocognitive understanding of the incident. When the decision problem was non-time-bounded, involved multiple agencies, and identification of superordinate goals was lacking, the communication between agencies decreased and agencies focused on within-agency information sharing. These barriers distracted teams from timely and efficient discussions on decisions and action execution with seeking redundant information, which resulted in decision inertia. Our study illustrates how naturalistic environments are conducive to examining relatively understudied concepts of decision inertia, failures to act, and shared situational macrocognition in situations involving large distributed teams
Between a rock and a hard place of geopolitically sensitive threats – critical incidents and decision inertia
While the SAFE-T model of decision making emphasizes naturalistic decision making, its potential for cross-comparative analysis of incidents with global implications remains underutilized, which the current paper aims to address. To this end, it draws upon open-source reports from unclassified American, British and Russian intelligence reports to explore the management of three types of 10 high-profile geopolitically sensitive threats from across the globe (verifying potential terrorist identity, hostage rescue and national/international security). Defining features of such incidents include decision makers’ ability to prospectively model competing scenarios in which they must select between options and where every outcome looks aversive and high risk (‘damned if you do or damned if you don’t decisions’). A frequent consequence of such calculations is ‘decision inertia’ (a failure to execute an important, irrevocable decision resulting in non-optimal consequences), or ‘implementation failure’ (a failure to make a choice). Combining the benefit of the theoretical framework and hindsight knowledge of the analyzed incidents, the paper facilitates theoretical understanding of decision inertia and failures to act. Encouraging the consideration of multiple scenario endings contingent on a wide spectrum of factors and unique cultural-historical context, it also helps identify past decision errors in order to inform assessment and management of similar geopolitical threats in the future
The role of information sharing on decision delay during multiteam disaster response
© 2019, The Author(s). Multiteam systems (MTSs) are comprised of two or more interconnected teams working toward shared superordinate goals but with unique sub-goals. To date, research has predominantly focused on how decisions are made and has viewed these cognitive processes as occurring within individuals. However, for MTSs operating in extreme environments such as disasters, it is often not a question of how decisions are made, but what is causing delays and failures to make decisions. To understand the causes of decision delay within these complex networks, it is important to focus on decision processes at the multiteam level. Using naturalistic observational and interview data collected during a multi-site, multiteam emergency response to a large-scale disaster exercise, this study examines both information sharing (what was shared, with whom, how long this took), and decision processes across teams (situational awareness—SA, plan formulation, and plan execution). Findings demonstrate that interdependencies in cognitive processes exist across individuals where goals overlap. Decision delay is not only caused by failure to develop SA within a team preventing their ability to formulate and execute plans but also by the inability of other teams to execute their plans. The implications of these findings for developing targeted interventions are discussed
Imagining grim stories to reduce redundant deliberation in critical incident decision-making
Redundant deliberation is a cognitively demanding form of inertia in which a decision-maker fails to gain any additional advantage by thinking about a problem compared to the risk of failing to act and deal with the problem. It most commonly occurs where there is no standard operating procedure (to help provide guidance) or where experience is lacking. This article argues that training interventions, including ‘grim storytelling’, must focus on supporting decision-makers’ ability to imagine rare, high-impact events, and construct ‘least–worst’ scenarios to help them anticipate, prevent, mitigate, adapt to and recover from such threats
The Effects of Intelligence and Personality on Performance in Simulated Interrogation Scenarios
The paper explores the relationships between individual differences in intelligence and personality, and the ability to extract critical information (and identify missing but required information) from a suspect’s brief sheet (i.e., model formulation) and develop a suitable line of questioning (i.e., approach strategizing) in interrogation scenarios. We hypothesized that cognitive flexibility, emotion management, low need for closure, and rapport would all be predictors of these abilities. Two hundred and seventy four participants of different backgrounds were exposed to two interrogation scenarios to assess model formation and approach strategizing abilities, as well as intelligence and personality tests. Benchmarks for performance were measured against two experienced interrogators and two psychologists’ calibrated performance. In terms of overall performance, only rapport and cognitive flexibility were significant positive predictors. Whereas only rapport was a positive predictor of approach strategizing, both rapport and cognitive flexibility were positive predictors of model formation. In conclusion, the data from the early stage of our project suggests that the examined factors should be carefully considered when training and selecting optimal interrogators. Though previous research has identified a number of individual differences in intelligence and personality that are important in demanding law-enforcement contexts, ours is the first to explore them with respect to effective interrogator performance
