1信息资本主义及互联网的劳工显示文摘本文认为在信息资本主义中,阶级的概念不能画地为牢地将资本家归为一个阶级,而将劳工划为另一类阶级。阶级的概念必须扩展到每位创造以及再创造共同经验空间的个人,例如包括在互联网上通过实践生产内容的用户。这些空间和经验被占用了,从而为资本所征用和开发,且为资本积累效劳。信息资本主义的崛起要求我们重新思考阶级的概念并将其与脑力劳动结合起来。Christian Fuchs 陈婉琳(译) 黄炎宁(译) 2014新闻大学2014,,5:19
2Sedimentation acceleration of remanent iron oxide by magnetic flocculation显示文摘Sedimentation based processes are widely used in industry to separate particles from a liquid phase. Since the advent of the 'Nanoworld' the demand for effective separation technologies has rapidly risen, calling for the development of new separation concepts, one of which lies in hybrid separation using the superposition of a magnetic field for magnetic particles. Possible product portfolio of such separation consists of pigment production, nanomagnetics production for electronics and bio separation. A promising step in that direction is magnetic field enhanced cake filtration, which has by now progressed from batch to continuous operation. In sedimentation processes in a mass force field the settling behaviour of particles strongly depends on physico-chemical properties, concentration and size distribution of the particles. By adjusting the pH, the interparticle forces, in particular the electrostatic repulsion, can be manipulated. For remanent magnetic particles such as magnetite, pre-treatment in a magnetic field could lead to a change of interparticle interactions. By magnetizing the particles apart from van der Waals attraction and electrostatic repulsion, an additional potential is induced, the magnetic attraction, which could easily dominate the other potentials and result in agglomeration in the primary minimum. By sedimentation analysis, a wide spectrum of parameters like pH, magnetic field strength and concentration have been investigated. The results show a strong increase of sedimentation velocity by magnetic flocculation of the raw suspension. This leads to a rise in throughput due to the acceleration of sedimentation kinetics by imparting a non-chemical interaction to the physico-chemical properties in the feed stream of the separation apparatus.Mathias Stolarski Christian Eichholz Benjamin Fuchs Hermann Nirschl 2007China Particuology2007,5,1:12
3政治经济学视野下的媒介产业资本化显示文摘在媒介和传播研究中,传播政治经济学的批判路径鲜有提及。去管制化、私有化、数字化、集中化和全球化等因素共同作用,导致了媒介产业结构发生明显改变。从学术研究的角度看,将媒介产业的发展与“失控”(unleashed)资本主义的发展紧密联系在一起分析尤为重要。因此,本文表明,从政治经济学的视角出发,我们不仅能够考察资本主义在全球范围内成为占主导地位的经济体系和社会制度的发展过程,而且也能够在一定程度上以一种学理上自洽的方式预测媒介产业经济化和商业化的进程及其原因、形式、后果。马克思对政治经济学的批判是站在历史唯物主义者的角度对社会进行的分析,他的理论为我们进一步分析、批判当代资本主义提供了理论来源。在此基础上,本文结合当前媒介产业资本化进程的特殊性,分析了资本主义生产方式和资本主义社会形态固有的基本特征、运作模式和“规律”。曼弗雷德·诺切 杨嵘均(译) 程琳(译) Christian Fuchs 2022国外社会科学前沿2022,,3:2

13Software improvement for evaluation of laryngopharyngeal pH testing(Restech)——a comparison between Data View 3 and 4显示文摘BACKGROUND When gastroesophageal reflux contents reach above the upper esophageal sphincter,patients may,in addition to typical reflux symptoms,present with atypical,extraesophageal symptoms related to laryngopharyngeal reflux(LPR).Surgical treatment of LPR has shown to lead to 70%symptom improvement,however no gold standard for the diagnosis of LPR exists.In 2007,the Restech Dx-pH was released as a valid method to measure acid exposure above the upper esophageal sphincter.Recently,a new software update was introduced for analysis of measured pH data and calculation of composite scores.The effect of the changes applied to the new software version have not yet been analyzed.AIM To compare results generated by Data View 3 to the most recently released Data View 4.METHODS All patients with gastroesophageal reflux disease symptoms were seen in a specialized surgical outpatient clinic for gastrointestinal function testing.Retrospective chart review was performed of all patients presenting with suspected gastroesophageal reflux disease and extraesophageal reflux symptoms,who underwent laryngopharyngeal pH monitoring using the Restech Dx-pH system(Respiratory Technology Corp.,Houston,TX,United States)and simultaneous esophageal pH monitoring.Data View 3 and Data View 4 were used to evaluate Restech studies obtained.Diary entries such as mealtimes,supine and upright periods,and symptoms were entered manually to ensure accuracy and precise conversion of data between both software versions.Paired t test was performed for statistical analysis of results.RESULTS A total of 174 patients(63.8%female)met inclusion criteria,all suffering from extraesophageal reflux symptoms as well as typical gastroesophageal reflux disease symptoms.Mean RYAN score upright was 48.77 in Data View 3 compared to 22.17 in Data View 4,showing a significant difference(~aP=0.0001).Similar results were shown for supine period(mean RYAN Score Data View 35.29 vs 1.42 in Data View 4,~cP=0.0001).For upright periods 80 patients showed a decrease of value of the RYAN score with a mean of-58.9(mean 51.1%decrease).For supine position 25 patients showed a decrease of value of the RYAN score with a mean of-15.13[range(-153.44)–(-0.01)],which equals a mean decrease of value of 44.5%.Ten patients showed no oropharyngeal acid exposure in Data View 3,but mild/moderate(n=7)or severe(n=3)acid exposure in Data View 4.Correlation with positive esophageal pH measurement was improved in all 10 patients.CONCLUSION Results of both software versions cannot be compared to each other.However,our data suggests that Data View 4 may be an improvement of the Restech pH measurement in the evaluation of LPR.Dolores Thea Müller Elena Schulte Benjamin Babic Laura Knepper Claudia Fuchs Wolfgang Schroder Christiane J Bruns Jessica M Leers Hans Friedrich Fuchs 2020World Journal of Gastrointestinal Surgery2020,12,5:1
