Comparison of different ultra-high-frequency transponder ear tags for simultaneous detection of cattle and pigs

AbstractElectronic animal identification is an important technology in modern animal husbandry providing great benefits. Low-frequency applications are state-of-the-art within the radio frequency identification of animals. Quasi-simultaneous detection of several animals and reading of the transponders over longer distances is impossible with low-frequency systems. Ultra-high-frequency (UHF) applications are suitable for this purpose. However, UHF systems have disadvantages through their susceptibility to metallic surfaces and liquids. Thus, the reflection and absorption of electromagnetic radiation in the animals' environment is often problematic. Consequently, an adjustment of the transponder ear tags regarding mechanical stability and functionality close to water (ear tissue) is necessary. In this project, targeted adjustments and a further development of UHF transponder ear tags concerning the resonance frequency were made. Three trials with cattle and two trials with pigs were performed in this study. Cattle were driven through a reader gate for ten rounds and six different types of transponder ear tags designed in-house were tested. The influence of the environment (indoor vs. outdoor), reader orientation at the gate (sideways vs. above) and output power of the readers (1.0 vs. 0.5W) were tested in two experiments. The average number of readings per round and the reading rates of the transponder ear tag types were taken as target variables. In the trials with pigs, three transponder ear tag types were compared. The animals were driven through the gate for five rounds per repetition, but neither the reader output power nor the reader orientation were varied. The pig experiments were performed indoors.The results of the cattle experiments showed that the average number of readings per round and the reading rates were significantly higher indoors compared to outdoors. The reader output power of 1.0W achieved significantly better results compared to 0.5W. The same applied to the reader orientation ‘above’ compared to ‘sideways’. It could also be shown that an improvement of the transponder and, thus, an adjustment to the animal's ear could be achieved during transponder ear tag type development. A maximum reading rate of 100% was reached with the cattle transponder types finally developed (B3-4, B4-4 and B5).In addition, an average reading rate of 100% was achieved for one pig transponder ear tag type (C2). However, these experiments have to be treated with caution due to a very low sample size

Late 1920s film theory and criticism as a test-case for Benjamin’s generalizations on the experiential effects of editing

This article investigates Walter Benjamin’s influential generalization that the effects of cinema are akin to the hyper-stimulating experience of modernity. More specifically, I focus on his oft-cited 1935/36 claim that all editing elicits shock-like disruption. First, I propose a more detailed articulation of the experience of modernity understood as hyper-stimulation and call for distinguishing between at least two of its subsets: the experience of speed and dynamism, on the one hand, and the experience of shock/disruption, on the other. Then I turn to classical film theory of the late 1920s to demonstrate the existence of contemporary views on editing alternative to Benjamin’s. For instance, whereas classical Soviet and Weimar theorists relate the experience of speed and dynamism to both Soviet and classical Hollywood style editing, they reserve the experience of shock/disruption for Soviet montage. In order to resolve the conceptual disagreement between these theorists, on the one hand, and Benjamin, on the other, I turn to late 1920s Weimar film criticism. I demonstrate that, contrary to Benjamin’s generalizations about the disruptive and shock-like nature of all editing, and in line with other theorists’ accounts, different editing practices were regularly distinguished by comparison to at least two distinct hyper-stimulation subsets: speed and dynamism, and shock-like disruption. In other words, contemporaries regularly distinguished between Soviet montage and classical Hollywood editing patterns on the basis of experiential effects alone. On the basis of contemporary reviews of city symphonies, I conclude with a proposal for distinguishing a third subset – confusion.

Masculinity and help-seeking among men with depression: a qualitative study

Background: Many studies indicate that men are more reluctant to seek help for mental health problems than women. Traditional ideas of masculinity are often seen as a cause of this phenomenon. However, little is known about the diversity of experiences during the processes of help-seeking and service use among men with depression who have already utilized mental health services. This study aims to explore men's experiences and attitudes toward depression, help-seeking, and service use in order to develop gender-sensitive services. Methods: Narrative-biographical interviews were conducted with men treated for depression (n = 12). Interview topics included individual experience with depression, help-seeking behavior, and mental health service use. Transcripts were analyzed using qualitative content analysis. Results: Before seeking treatment, men's help-seeking behavior was negatively affected by internalized masculine norms. However, findings indicate a change of attitudes toward depression after mental health service use. Men with depression emphasized a salutogenic perspective toward mental health problems and critically reflected on masculine norms. The positive function of men-only groups were described as key for successful service use. Conclusions: Men with depression reported experiences toward help-seeking and service use on four different levels: (i) attitudes toward depression, (ii) perception of societal views on depression, (iii) experiences within the family context and (iv) experiences with mental health services. Interventions to reduce the stigma of being “unmanly” and to improve men's capacity to cope with being unable to work should be developed. Peer-led men-only groups may increase participants' self-esteem and assist in disclosing weaknesses. In the context of GPs' mediating role, training for health professionals concerning the impact of masculine norms on mental health is recommended

Masculinity norms and occupational role orientations in men treated for depression

PURPOSE:A traditional male role orientation is considered to increase the risk of depression and preventing men from disclosing symptoms of mental illness and seeking professional help. Less is known about the variance of masculinity orientations in men already treated for depression and their role in the treatment process. In this study, patterns of masculinity norms and work role orientations will be identified among men treated for depression. Associations of these patterns with depressive symptoms, stigma and delay in professional help-seeking will be investigated. METHODS:In a cross-sectional study, male role orientations (MRNS), work-related attitudes (AVEM), symptoms of mental disorders (PHQ), and attitudes related to stigma of mental illness (DSS) were assessed by standardized methods in a sample of 250 men treated for depression in general medical, psychiatric and psychotherapeutic services. Data were analyzed by means of latent profile analysis (LPA), by multinomial and linear regression models, and by path analysis. RESULTS:The results of LPA revealed three latent classes of men treated for depression. Men assigned to class one reported a less traditional male role orientation, low professional ambitions and low coping capacities; men assigned to class two reported a traditional masculinity orientation, high professional ambitions but low coping capacities; men assigned to class three reported less traditional masculinity tended orientations, medium professional ambitions and high coping capacities. Men assigned to classes one and two to have more stigmatizing attitudes, longer periods of untreated illness and more severe symptoms of mental disorders, in comparison to men assigned to class three. CONCLUSIONS:Overall, this study reveals that traditional masculinity norms and work-role orientations in men treated for depression are associated with a worse mental health status. Our study results also suggest that a slackening of traditional masculinity norms is associated with improved psychological well-being if it does not coincide with a complete distancing from professional ambitions and a lack of ability to cope with professional stress

Identification of a miRNA based model to detect prognostic subgroups in patients with aggressive B-cell lymphoma

In order to differentiate prognostic subgroups of patients with aggressive B-cell lymphoma, we analyzed the expression of 800 miRNAs with the NanoString nCounter human miRNA assay on a cohort of 228 FFPE samples of patients enrolled in the RICOVER-60 and MegaCHOEP trials. We identified significant miRNA signatures for overall survival (OS) and progression-free survival (PFS) by LASSO-penalized linear Cox-regression. High expression levels of miR-130a-3p and miR-423-5p indicate a better prognosis, whereas high levels of miR-374b-5p, miR-590-5p, miR-186-5p, and miR-106b-5p increase patients' risk levels for OS. Regarding PFS high expression of miR-365a-5p in addition to the other two miRNAs improves the prognosis and high levels of miR374a-5p, miR-106b-5p, and miR-590-5p, connects with increased risk and poor prognosis. We identified miRNA signatures to subdivide patients into two different risk groups. These prognostic models may be used in risk stratification in future clinical trials and help making personalized therapy decisions
