Überlegungen zur theoretischen Fundierung der Disziplin Wirtschaftsinformatik, ausgehend von der allgemeinen Systemtheorie

Using general system theory as a theoretical foundation of business information systems science. The science of business information systems is looking for its theoretical foundations. In this article general system theory is adapted to serve as such a theoretical foundation. The adapted general system theory is reconstructed using the structuralistic approach to reveal the empirical claims of this theory and to analyse scientific progress in the science of business information systems. This revised version was published online in August 2006 with corrections to the Cover Date.     

Research Findings Concerning Excavated Texts and Learning in Early China

In the course of Chinese history, we find three instances of important and deliberate attempts to reconstruct ancient history. In the first two, the main path followed in the reconstruction process concerned setting in order and recovering the traditional writings. But recently, the main path is to confirm the genuineness of the traditional writings, correcting errors and filling in omissions in the traditional concepts according to the “method of double proof.” Based on this, I aim to advance a new understanding of some key controversial issues in the history of learning in early China, concerning Confucius and the Book of Changes, the Analects and the Analects-kind texts, the School of Zisi and its literary output, Lao Zi the man and the book, and the dates of Wen Zi, Guanyin Zi, and Lie Zi. On this basis, I conclude that the development of pre-Qin philosophy went through four periods, with two significant turning points therein.     

Reconstructing Complex Analogy Argumentation in Judicial Decisions: A Pragma-Dialectical Perspective

Empirical research in the field of legal interpretation shows that, in many cases, analogy argumentation is complex rather than simple. Traditional analytical approaches to analogy argumentation do not explore that complexity. In most cases analogy argumentation is reconstructed as a simple form of argumentation that consists of two premises and a conclusion. This article focuses on the question of how to analyze and evaluate complex analogy argumentation. It is shown how the pragma-dialectical approach provides clues for analyzing complex analogy argumentation and how the criteria for evaluating analogy argumentation can be used to reconstruct these types of complex analogy argumentation in Dutch case law. The critical questions in the argumentation scheme do not only serve as a tool for analyzing arguments justifying analogy argumentation, but are also helpful in analyzing arguments against a specific analogy argumentation.     

Begging the Question: A Case Study

The essay starts by presenting two accounts of begging the question, John Biro's epistemic account and David Sanford's doxastic account. After briefly comparing these accounts, the essay will study an argument suspected of begging the question and subsequently apply the epistemic and doxastic accounts to this test case. It is found that the accounts of Biro and Sanford do not analyse the test case adequately, therefore a new account is developed using the idea of a knowledge-base.     

Two dogmas of analytic historiography

ABSTRACT

Starting from an analogy with Quine’s two dogmas of empiricism, I offer a (neo-Kantian) critique of two dogmas of analytic historiography: the belief in a cleavage between the justification of a philosophical claim and an account of its genesis and the belief in rational reconstructionism. I take Russell’s rational reconstruction of Leibniz’s philosophy as my detailed example.     

An extended application ‘Brain Q’ processing EEG and MEG data of finger stimulation extended from ‘Zeffiro’ based on machine learning and signal processing

GoalTo apply signal processing and machine learning skills and knowledge in processing the EEG and MEG signal and further localize and evaluate the source of the finger stimulation.MethodsCognitive control is usually applied in information processing and behavioral response. In the preprocessing, baseline correction is implemented to analyze the pre-stimuli, combining ERP to mark the event related potential, studying the time-locked only behavior. Z-score transform, coherence and spec trum are calculated and analyzed in the functional connectivity analysis.In addition to the functional analysis, Bayes Optimizer evaluates the neuro imaging according to the hierarchical Bayes. The introduction of the application is described from both user and developer’s prospects. Results: Introduction of both user and developers aspects, on its modules from pre-processing, functional analysis and results visualization and evaluation is conducted with one specific clinical data case, including the correlation is higher especially on gamma band and the MVAR coherence on the whole source space depicting the relation between different regions, especially on somatosensory (compared by thalamus) when stimulated by finger activity, phase-lock property of the E/MEG signal and etc. Compared to a manual selection, the scaling parameter prediction can be improved with support vector machine (SVM). The evaluation results with Bayes Optimization, location prediction is superior in the somatosensory area and in the thalamus, the total reconstructed source space is larger, one of the realization of cognitive system comparing different kernels and classifiers. The SVM and discriminant classifier gives similar results evaluating the dipole localization and the parameter choice related as well to the shape parameter, noise level, hyperprior and etc.ConclusionApproaches of Brain Q are found to be suitable for pre-processing for the EEG and MEG data. The system is capable of functional analysis including coherence and spectral related computation. Machine learning techniques are conducted as well to analyze and evaluate the result of the dipole reconstruction and help to predict the better model parameters and the localization of the origin dipoles. A case on finger stimulation clinical data is conducted and the results of the analysis temporarily and spatially manifests its functionality for users and potential extensions for developers.     

The Influences of Category Learning on Perceptual Reconstructions

We explore different ways in which the human visual system can adapt for perceiving and categorizing the environment. There are various accounts of supervised (categorical) and unsupervised perceptual learning, and different perspectives on the functional relationship between perception and categorization. We suggest that common experimental designs are insufficient to differentiate between hypothesized perceptual learning mechanisms and reveal their possible interplay. We propose a relatively underutilized way of studying potential categorical effects on perception, and we test the predictions of different perceptual learning models using a two-dimensional, interleaved categorization-plus-reconstruction task. We find evidence that the human visual system adapts its encodings to the feature structure of the environment, uses categorical expectations for robust reconstruction, allocates encoding resources with respect to categorization utility, and adapts to prevent miscategorizations.     

Combining total laparoscopic hysterectomy and bilateral salpingo-oophorectomy with subcutaneous mastectomy in trans men: The effect on safety outcomes

Abstract

Background: Masculinizing mastectomy is the most requested gender affirming surgery (GAS) in trans men, followed by genital GAS. Mastectomy and total laparoscopic hysterectomy, with or without bilateral salpingo-oophorectomy (TLH?±?BSO), can both be performed in one single operation session. However, data on complication rates of the combined procedure is scarce and no consensus exists on the preferred order of procedures.

Aims: To compare safety outcomes between mastectomy performed in a single procedure with those when performed in a combined procedure and assess whether the order of procedures matters when they are combined.

Methods: A retrospective chart review was performed of trans men who underwent masculinizing mastectomy with or without TLH?±?BSO in a combined session. The effects of the surgical procedure on complication and reoperation rate of the chest were assessed using logistic regression.

Results: In total, 480 trans men were included in the study. Of these, 212 patients underwent the combined procedure. The gynecological procedure was performed first in 152 (71.7%) patients. In the total sample, postoperative hematoma of the chest occurred in 11.3%; 16% in the combined versus 7.5% in the single mastectomy group (p?=?0.001). Reoperations due to hematoma of the chest were performed in 7.5% of all patients; 10.8% in the combined versus 4.9% in the single mastectomy group (p?=?0.017). The order of procedures in the combined group had no significant effect on postoperative hematoma of the chest (p?=?0.856), and reoperations (p?=?0.689).

Conclusion: Combining masculinizing mastectomy with TLH?±?BSO in one session was associated with significantly more hematoma and reoperations compared with separately performing mastectomy. This increased risk of complications after a combined procedure should be considered when deciding on surgical options. The order of procedures in a combined procedure did not have an effect on safety outcomes.     

肢体自然重建理念——一种人文关怀治疗

著名的医学家、哲学家Hippocrates在公元前4世纪就指出：医生的责任仅在于促进疾病的自然康复过程,而非阻拦这个过程.患者得以治愈的根据是患者自身存在的康复能力;医生首先必须清楚：自己所治疗的对象是人,是有生命的、有思想的、活在社会上的人,而不是被修理的物件.医生能够做到的只是为患者创造或提供一定的有利于康复的条件.20世纪50年代,前苏联骨科专家Ilizarov发现了张力-应力法则,并因此创造出的牵拉再生、自然重建技术,正是很好地诠释了Hippocrates的思想.
