"Ist dort... ha, ha, ha, der... der 'Erfinder der deutschen Popliteratur?'" Continuidad y evolución de la Neue Deutsche Popliteratur en la obra de Jo…

2023

La Neue Deutsche Popliteratur ha estado asociada desde sus inicios a la Spaßgesellschaft. El consumismo, el ritmo desenfrenado y la constante búsqueda del placer y la diversión que recogían los textos desarrollados por los Popliteraten eran reflejo de una época en la que el fin último de la sociedad era el placer y la diversión individual, alejándose de la búsqueda del bienestar colectivo. Sin embargo, los terribles atentados cometidos el 11 de septiembre de 2001 en Nueva York supusieron el fin de la Spaßgesellschaft y, a ojos de la crítica especializada del momento, también el fin de una literatura estrechamente vinculada al contexto en que surgió. Esta tesis analiza la continuidad y evolu…

Excessiveness in Symptom-Related Thoughts, Feelings, and Behaviors: An Investigation of Somatic Symptom Disorders in the General Population.

2020

OBJECTIVE The diagnostic criteria of somatic symptom disorder (SSD) emphasize that somatic symptoms receive disease value once they are accompanied by excessive thoughts, feelings, or behaviors. The main objective of this study was to examine what constitutes excessiveness in psychological reactions to somatic complaints and how excessive symptom-related behavior influences self-reported health status and health care utilization. METHODS A national, representative general population survey was performed between January and March 2016 in Germany, including 2395 individuals older than 13 years. Self-report questionnaires (Somatic Symptom Scale-8, Somatic Symptom Disorder-B Criteria Scale) wer…

Autofluorescence imaging of basal cell carcinoma by smartphone RGB camera

2015

The feasibility of smartphones for in vivo skin autofluorescence imaging has been investigated. Filtered autofluorescence images from the same tissue area were periodically captured by a smartphone RGB camera with subsequent detection of fluorescence intensity decreasing at each image pixel for further imaging the planar distribution of those values. The proposed methodology was tested clinically with 13 basal cell carcinoma and 1 atypical nevus. Several clinical cases and potential future applications of the smartphone-based technique are discussed.

Modern health worries and idiopathic environmental intolerance.

2008

Abstract Objective We conducted two studies to test whether modern health worries (MHWs) were associated with central features of a condition called idiopathic environmental intolerance (IEI) and medical care utilization. Methods In Study 1, 474 Internet users completed an Internet-based questionnaire that assessed MHWs, IEI features, and medical care utilization. In Study 2, the diagnostic specificity of MHWs was investigated by comparing the level of MHWs of three diagnostic groups: 46 people with IEI, 38 people with somatoform disorder but without IEI, and 46 people with neither IEI nor somatoform disorder. Results The good psychometric properties of the MHW scale were confirmed. MHWs we…

A novel scheme for privacy preserving in RBAC

2013

Role Based Access Control (RBAC) Model has been proved to be quite useful and has drawn a lot of research interest over the last fifteen years. In this paper we discuss general context-aware RBAC model. We analyze potential privacy threats associated with use of context-aware RBAC and propose a novel scheme that provides privacy-preserving for access models based on RBAC.

The importance of management innovation and consultant services on ERP implementation success

2011

Enterprise resource planning (ERP) implementation has been an important activity for improving efficiency. However, an ERP system is a critical investment that can significantly affect future performance of a company. Many ERP projects report an unusually high failure rate. This study empirically investigates the involvement of management consultants in ERP implementation success. The results from our field survey of 134 ERP end-users in Spanish ceramic tile companies show that ERP implementation success significantly depends on the quality of consultant services. The results also indicate the importance of internal management throughout the learning process. Overall, these findings contrib…

Zinc accelerates respiratory burst termination in human PMN

2021

The respiratory burst of phagocytes is essential for human survival. Innate immune defence against pathogens relies strongly on reactive oxygen species (ROS) production by the NADPH oxidase (NOX2). ROS kill pathogens while the translocation of electrons across the plasma membrane via NOX2 depolarizes the cell. Simultaneously, protons are released into the cytosol. Here, we compare freshly isolated human polymorphonuclear leukocytes (PMN) to the granulocytes-like cell line PLB 985. We are recording ROS production while inhibiting the charge compensating and pH regulating voltage-gated proton channel (HV1). The data suggests that human PMN and the PLB 985 generate ROS via a general mechanism,…

Comparative Quantitative Analysis of Porcine Optic Nerve Head and Retina Subproteomes

2019

Optic nerve head (ONH) and retina (RET) are the main sites of damage in neurodegenerative optic neuropathies including glaucoma. Up to date, little is known about the molecular interplay between these two adjoining ocular components in terms of proteomics. To close this gap, we investigated ONH and RET protein extracts derived from porcine eyes (n = 12) (Sus scrofa domestica Linnaeus 1758) using semi-quantitative mass spectrometry (MS)-based proteomics comprising bottom-up LC&ndash
