The performativity of nonviolent protest in South Asia (1918 - 1948)

This study seeks to address a gap in the study of nonviolent action. The gap relates to the question of how nonviolence is performed, as opposed to the meaning or impact of nonviolent politics. The dissertation approaches the history of nonviolent protest in South Asia through the lens of performance studies. Such a shift allows for concepts such as performativity and theatricality to be tested in terms of their applicability and relevance to contemporary political and philosophical questions. It also allows for a different perspective on the historiography of nonviolent protest. Using concepts, modes of analysis and tropes of thinking from the emerging field of performance studies, the dissertation analyses two different cases of nonviolent protest, asking how politics is performatively constituted. The first two sections of this study set out the parameters of the key terms of the dissertation: nonviolence and performativity, by tracing their genealogies and legacies as terms. These histories are then located as an intersection in the founding of the nonviolent. The case studies at the analytical core of the dissertation are: fasting as a method in Gandhi's political arsenal, and the army of nonviolent soldiers in the North-West Frontier Province, known as the Khudai Khidmatgar. The study begins with an overview of current theorisations of nonviolence. The approach to the subject is through an investigation of commonly held misconceptions about nonviolent action, such as its supposed passivity, the absence of violence, its ineffectiveness and its spiritual basis. This section addresses the lacunae within existing theories of nonviolence and points to possible fertile spaces for further exploration. Section 3 offers an overview of the different shades of the concept of performativity, asking how it is used in various contexts and how these different nuances can be viewed in relation to each other. The dissertation explores how a theory of performativity may be correlated to the theorisation of nonviolence. The correlations are established in four boundary areas: action/inaction, violence/absence of violence, the actor/opponent and the body/spirit. These boundary areas allow for a theorising of nonviolent action as a performative process. The first case study is Gandhi's use of the fast as a method of nonviolent protest. Using a close reading of his own writings, speeches and letters, as well as a reading of responses to his fast in British newspapers and within India, the dissertation asks what made fasting into Gandhi's most favoured mode of protest and political action. The study reconstructs his unique praxis of the fast from a performative perspective, demonstrating how display and ostentation are vital to the political economy of the fast. It also unveils the cultural context and historical reservoir of body practices, which Gandhi drew from and adapted into 'weapons' of political action. The relationship of Gandhian nonviolence to the body forms a crucial part of the analysis. The second case study is the nonviolent army of the Pashtuns, Khudai Khidmatgar (KK), literally Servants of God. This anti-imperialist movement in the North-West Frontier Province of what is today the border between Pakistan and Afghanistan existed between 1929 and 1948. The movement adopted the organisational form of an army. It conducted protest activities against colonial rule, as well as social reform activities for the Pashtuns. This group was connected to the Congress party of Gandhi, but the dissertation argues that their conceptualisation and praxis of nonviolence emerged from a very different tradition and worldview. Following a brief introduction to the socio-political background of this Pashtun movement, the dissertation explores the activities that this nonviolent army engaged in, looking at their unique understanding of the militancy of an unarmed force, and their mode of combat and confrontation. Of particular interest to the analysis is the way the KK re-combined and mixed what appear to be contradictory ideologies and acts. In doing so, they reframed cultural and historical stereotypes of the Pashtuns as a martial race, juxtaposing the institutional form of the army with a nonviolent praxis based on Islamic principles and social reform. The example of the Khudai Khidmatgar is used to explore the idea that nonviolence is not the opposite of violent conflict, but in fact a dialectical engagement and response to violence. Section 5, in conclusion, returns to the boundary areas of nonviolence: action, violence, the opponent and the body, and re-visits these areas on a comparative note, bringing together elements from Gandhi's fasts and the practices of the KK. The similarities and differences in the two examples are assessed and contextualised in relation to the guiding question of this study, namely the question of the performativity of nonviolent action.

How to assess the external validity of therapeutic trials: a conceptual approach

Background External validity of study results is an important issue from a clinical point of view. From a methodological point of view, however, the concept of external validity is more complex than it seems to be at first glance. Methods Methodological review to address the concept of external validity. Results External validity refers to the question whether results are generalizable to persons other than the population in the original study. The only formal way to establish the external validity would be to repeat the study for that specific target population. We propose a three-way approach for assessing the external validity for specified target populations. (i) The study population might not be representative for the eligibility criteria that were intended. It should be addressed whether the study population differs from the intended source population with respect to characteristics that influence outcome. (ii) The target population will, by definition, differ from the study population with respect to geographical, temporal and ethnical conditions. Pondering external validity means asking the question whether these differences may influence study results. (iii) It should be assessed whether the study's conclusions can be generalized to target populations that do not meet all the eligibility criteria. Conclusion Judging the external validity of study results cannot be done by applying given eligibility criteria to a single target population. Rather, it is a complex reflection in which prior knowledge, statistical considerations, biological plausibility and eligibility criteria all have place.

[The thoracoscopic talc pleurodesis with intraoperative pleural biopsy - a retrospective analysis in patients with malignant pleural effusion]

The thoracoscopic pleurodesis with talc is an established therapy in case of malignant pleural effusion. With the instillation of talc a -localised inflammation is induced. However, some-times it turns into a severe systemic reaction. In this study of the postoperative course, the -question is examined whether a pleural biopsy is an additional risk factor for morbidity and mortality after talc pleurodesis.

Is IgG galactosylation the relevant factor for pregnancy-induced remission of rheumatoid arthritis?

During pregnancy, most patients with rheumatoid arthritis (RA) experience spontaneous improvement of their disease activity. Among the soluble candidates that have been investigated in search for the most relevant disease-remitting factor are the galactosylation levels of immunoglobulin G (IgG). In RA, a higher percentage of IgG lacking the terminal galactose residues, thought to play a pro-inflammatory role, is found. During pregnancy, however, IgG galactosylation levels increase and correlate with improved disease activity. The question remains whether the increase in IgG galactosylation during pregnancy is a mere epiphenomenon or a true remission-inducing factor.

Urine tested positive for ethyl glucuronide and ethyl sulphate after the consumption of "non-alcoholic" beer

In abstinence maintenance programs, for reissuing the driving licence and in workplace monitoring programs abstinence from ethanol and its proof are demanded. Various monitoring programs that mainly use ethyl glucuronide (EtG) as alcohol consumption marker have been established. To abstain from ethanol, but not from the taste of alcoholic beverages, in particular non-alcoholic beer has become more and more popular. In Germany, these "alcohol-free" beverages may still have an ethanol content of up to 0.5vol.% without the duty of declaration. Due to severe negative consequences resulting from positive EtG tests, a drinking experiment with 2.5L of non-alcoholic beer per person was performed to address the question of measurable concentrations of the direct metabolites EtG and EtS (ethyl sulphate) in urine and blood. Both alcohol consumption markers - determined by LC-MS/MS - were found in high concentrations: maximum concentrations in urine found in three volunteers were EtG 0.30-0.87mg/L and EtS 0.04-0.07mg/L, i.e., above the often applied cut-off value for the proof of abstinence of 0.1mg EtG/L. In the urine samples of one further volunteer, EtG and EtS concentrations cumulated over-night and reached up to 14.1mg/L EtG and 16.1mg/L EtS in the next morning's urine. Ethanol concentrations in blood and urine samples were negative (determined by HS-GC-FID and by an ADH-based method).

Randomized clinical trial comparing percutaneous closure of patent foramen ovale (PFO) using the Amplatzer PFO Occluder with medical treatment in patients with cryptogenic embolism (PC-Trial): rationale and design

Background Several studies have shown an association of cryptogenic stroke and embolism with patent foramen ovale (PFO), but the question how to prevent further events in such patients is unresolved. Options include antithrombotic treatment with warfarin or antiplatelet agents or surgical or endovascular closure of the PFO. The PC-Trial was set up to compare endovascular closure and best medical treatment for prevention of recurrent events. Methods The PC-Trial is a randomized clinical trial comparing the efficacy of percutaneous closure of the PFO using the Amplatzer PFO occluder with best medical treatment in patients with cryptogenic embolism, i.e. mostly cryptogenic stroke. Warfarin for 6 months followed by antiplatelet agents is recommended as medical treatment. Randomization is stratified according to patients age (<45 versus ≥45 years), presence of atrial septal aneurysm (ASA yes or no) and number of embolic events before randomization (one versus more than one event). Primary endpoints are death, nonfatal stroke and peripheral embolism. Discussion patients were randomized in 29 centers of Europe, Canada, and Australia. Randomization started February 2000. Enrollment of 414 patients was completed in February 2009. All patients will be followed-up longitudinally. Follow-up is maintained until the last enrolled patient is beyond 2.5 years of follow-up (expected in 2011).

A Blueprint for Buddhist Revolution: The Radical Buddhism of Seno’o Girō (1889–1961) and the Youth League for Revitalizing Buddhism

In the early decades of the twentieth century, as Japanese society became engulfed in war and increasing nationalism, the majority of Buddhist leaders and institutions capitulated to the status quo. One notable exception to this trend, however, was the Shinkō Bukkyō Seinen Dōmei (Youth League for Revitalizing Buddhism), founded on 5 April 1931. Led by Nichiren Buddhist layman Seno’o Girō and made up of young social activists who were critical of capitalism, internationalist in outlook, and committed to a pan-sectarian and humanist form of Buddhism that would work for social justice and world peace, the league’s motto was “carry the Buddha on your backs and go out into the streets and villages.” This article analyzes the views of the Youth League for Revitalizing Buddhism as found in the religious writings of Seno’o Girō to situate the movement in its social and philosophical context, and to raise the question of the prospects of “radical Buddhism” in twenty-first century Japan and elsewhere.

A closer look at the high affinity benzodiazepine binding site on GABAA receptors

Ligands of the benzodiazepine binding site of the GABA(A) receptor come in three flavors: positive allosteric modulators, negative allosteric modulators and antagonists all of which can bind with high affinity. The GABA(A) receptor is a pentameric protein which forms a chloride selective ion channel and ligands of the benzodiazepine binding site stabilize three different conformations of this protein. Classical benzodiazepines exert a positive allosteric effect by increasing the apparent affinity of channel opening by the agonist γ-aminobutyric acid (GABA). We concentrate here on the major adult isoform, the α(1)β(2)γ(2) GABA(A) receptor. The classical binding pocket for benzodiazepines is located in a subunit cleft between α(1) and γ(2) subunits in a position homologous to the agonist binding site for GABA that is located between β(2) and α(1) subunits. We review here approaches to this picture. In particular, point mutations were performed in combination with subsequent analysis of the expressed mutant proteins using either electrophysiological techniques or radioactive ligand binding assays. The predictive power of these methods is assessed by comparing the results with the predictions that can be made on the basis of the recently published crystal structure of the acetylcholine binding protein that shows homology to the N-terminal, extracellular domain of the GABA(A) receptor. In addition, we review an approach to the question of how the benzodiazepine ligands are positioned in their binding pocket. We also discuss a newly postulated modulatory site for benzodiazepines at the α(1)/β(2) subunit interface, homologous to the classical benzodiazepine binding pocket.

Theta burst TMS increases cerebral blood flow in the primary motor cortex during motor performance as assessed by arterial spin labeling (ASL)

Theta burst stimulation (TBS) is a novel variant of repetitive transcranial magnetic stimulation (rTMS), which induces changes in neuronal excitability persisting up to 1h. When elicited in the primary motor cortex, such physiological modulations might also have an impact on motor behavior. In the present study, we applied TBS in combination with pseudo continuous arterial spin labeling (pCASL) in order to address the question of whether TBS effects are measurable by means of changes in physiological parameters such as cerebral blood flow (CBF) and if TBS-induced plasticity can modify motor behavior. Twelve right-handed healthy subjects were stimulated using an inhibitory TBS protocol at subthreshold stimulation intensity targeted over the right motor cortex. The control condition consisted of within-subject Sham treatment in a crossover design. PCASL was performed before (pre TBS/pre Sham) and immediately after treatment (post TBS/post Sham). During the pCASL runs, the subjects performed a sequential fingertapping task with the left hand at individual maximum speed. There was a significant increase of CBF in the primary motor cortex after TBS, but not after Sham. It is assumed that inhibitory TBS induced a "local virtual lesion" which leads to the mobilization of more neuronal resources. There was no TBS-specific modulation in motor behavior, which might indicate that acute changes in brain plasticity caused by TBS are immediately compensated. This compensatory reaction seems to be observable at the metabolic, but not at the behavioral level.

Immune Activation Reduces Sperm Quality in the Great Tit

Mounting an immune response against pathogens incurs costs to organisms by its effects on important life-history traits, such as reproductive investment and survival. As shown recently, immune activation produces large amounts of reactive species and is suggested to induce oxidative stress. Sperm are highly susceptible to oxidative stress, which can negatively impact sperm function and ultimately male fertilizing efficiency. Here we address the question as to whether mounting an immune response affects sperm quality through the damaging effects of oxidative stress. It has been demonstrated recently in birds that carotenoid-based ornaments can be reliable signals of a male's ability to protect sperm from oxidative damage. In a full-factorial design, we immune-challenged great tit males while simultaneously increasing their vitamin E availability, and assessed the effect on sperm quality and oxidative damage. We conducted this experiment in a natural population and tested the males' response to the experimental treatment in relation to their carotenoid-based breast coloration, a condition-dependent trait. Immune activation induced a steeper decline in sperm swimming velocity, thus highlighting the potential costs of an induced immune response on sperm competitive ability and fertilizing efficiency. We found sperm oxidative damage to be negatively correlated with sperm swimming velocity. However, blood resistance to a free-radical attack (a measure of somatic antioxidant capacity) as well as plasma and sperm levels of oxidative damage (lipid peroxidation) remained unaffected, thus suggesting that the observed effect did not arise through oxidative stress. Towards the end of their breeding cycle, swimming velocity of sperm of more intensely colored males was higher, which has important implications for the evolution of mate choice and multiple mating in females because females may accrue both direct and indirect benefits by mating with males having better quality sperm.

Tactile sensibility of single-tooth implants and natural teeth under local anesthesia of the natural antagonistic teeth

The term osseoperception describes the capability of developing a subtle tactile sensibility over dental implants. The present clinical study aims at clarifying the question of how far tactile sensibility is to be attributed to the periodontium of the natural opposing tooth of the implant.

Moving beyond a descriptive aquatic toxicology: the value of biological process and trait information

In order to improve the ability to link chemical exposure to toxicological and ecological effects, aquatic toxicology will have to move from observing what chemical concentrations induce adverse effects to more explanatory approaches, that are concepts which build on knowledge of biological processes and pathways leading from exposure to adverse effects, as well as on knowledge on stressor vulnerability as given by the genetic, physiological and ecological (e.g., life history) traits of biota. Developing aquatic toxicology in this direction faces a number of challenges, including (i) taking into account species differences in toxicant responses on the basis of the evolutionarily developed diversity of phenotypic vulnerability to environmental stressors, (ii) utilizing diversified biological response profiles to serve as biological read across for prioritizing chemicals, categorizing them according to modes of action, and for guiding targeted toxicity evaluation; (iii) prediction of ecological consequences of toxic exposure from knowledge of how biological processes and phenotypic traits lead to effect propagation across the levels of biological hierarchy; and (iv) the search for concepts to assess the cumulative impact of multiple stressors. An underlying theme in these challenges is that, in addition to the question of what the chemical does to the biological receptor, we should give increasing emphasis to the question how the biological receptor handles the chemicals, i.e., through which pathways the initial chemical-biological interaction extends to the adverse effects, how this extension is modulated by adaptive or compensatory processes as well as by phenotypic traits of the biological receptor.

The evolutionary importance of cell ratio between notochordal and nucleus pulposus cells: an experimental 3-D co-culture study

Notochordal cells and nucleus pulposus cells are co-existing in the intervertebral disc at various ratios among different mammalians. This fact rises the question about the interactions and the evolutionary relevance of this phenomenon. It has been described that these relatively large notochordal cells are mainly dominant in early lifetime of all vertebrates and then differences occur with ageing. Human, cattle, sheep, and goat lose the cells with age, whereas rodents and lagomorphs maintain these throughout their lifetime.

Guidelines for the use and interpretation of assays for monitoring autophagy

In 2008 we published the first set of guidelines for standardizing research in autophagy. Since then, research on this topic has continued to accelerate, and many new scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Accordingly, it is important to update these guidelines for monitoring autophagy in different organisms. Various reviews have described the range of assays that have been used for this purpose. Nevertheless, there continues to be confusion regarding acceptable methods to measure autophagy, especially in multicellular eukaryotes. A key point that needs to be emphasized is that there is a difference between measurements that monitor the numbers or volume of autophagic elements (e.g., autophagosomes or autolysosomes) at any stage of the autophagic process vs. those that measure flux through the autophagy pathway (i.e., the complete process); thus, a block in macroautophagy that results in autophagosome accumulation needs to be differentiated from stimuli that result in increased autophagic activity, defined as increased autophagy induction coupled with increased delivery to, and degradation within, lysosomes (in most higher eukaryotes and some protists such as Dictyostelium) or the vacuole (in plants and fungi). In other words, it is especially important that investigators new to the field understand that the appearance of more autophagosomes does not necessarily equate with more autophagy. In fact, in many cases, autophagosomes accumulate because of a block in trafficking to lysosomes without a concomitant change in autophagosome biogenesis, whereas an increase in autolysosomes may reflect a reduction in degradative activity. Here, we present a set of guidelines for the selection and interpretation of methods for use by investigators who aim to examine macroautophagy and related processes, as well as for reviewers who need to provide realistic and reasonable critiques of papers that are focused on these processes. These guidelines are not meant to be a formulaic set of rules, because the appropriate assays depend in part on the question being asked and the system being used. In addition, we emphasize that no individual assay is guaranteed to be the most appropriate one in every situation, and we strongly recommend the use of multiple assays to monitor autophagy. In these guidelines, we consider these various methods of assessing autophagy and what information can, or cannot, be obtained from them. Finally, by discussing the merits and limits of particular autophagy assays, we hope to encourage technical innovation in the field.

Rwandan youth in the development of music industry

In this days for ever, the Rwandan youth are more active in the development of music industry, the recording studio are created every day, and the number of musician is increasing from one day to another day, it is too early to get the statistic; some of the youth are dropped out their studies to develop their career of music; the question was how many of them are developing their career to become the Professional? WHY IN THESE DAYS, RWANDAN YOUTH ARE WORKING HARDLY IN THE DEVELOPMENT OF MUSIC INDUSTRY?” it was not easy for me to get the accurate answers; some questions remains in my mind like -Are they working for money-music as a job (professional)? -Are they willing to become célèbre-stars? -Is it for the entertainment/Relaxing? -Is it because they love music? -Are they escaping the problems-Music as an escape domain? -Are they exploring their free time? -Are they using the music as the way of expressing their views? Those questions require analysing each question deeply, and getting the answers from the singers and listeners of music or DJ, in order to confirm the causes of being more active in music industry for the Rwandan youth. I am not interesting to make a deep research but to analyze and I hope this article will help the students and many researchers to develop and find out the exact causes. As my aim is to open the door for the researchers, briefly let us analyze all those above questions one to one based on the main causes as the motivation of forcing the Rwandan youth to be in the industry music.
