    'I'm as much an anarchist in theory as I am in practice': Fernando Pessoa's 'Anarchist banker' in a management education context

    Get PDF
    The performance of Fernando Pessoa?s novel The Anarchist Banker serves as an example for critical management education and allows for further insights into how anarchist theories may be reflected upon and practiced in a business school context. We explore elements of an ?anarchist aesthetics? that are created through dramaturgy, narration, and collective production and reception. The Anarchist Banker fits well with arts-based education in business schools and efforts to learn lessons for leadership through the use of drama. The literary source encourages to rethink salient issues in today?s global and finance-dominated capitalism and offers opportunities to search for alternative forms of organizing society and the economy by questioning charismatic leadership and managerial rhetoric in favor of collective reasoning. Elements of an anarchist aesthetic include the deconstruction of the hero and authoritarian discourse, dialogue and polyphony, collectivity and obstructionism that are at play artistically and socially, integrating anarchist theory and practice in content and form. The topic links to new forms of resistance, with critical artists opposing the business world and academics attempting to play out the ?banker? versus the ?anarchist?

    Aus der Literaturrecherche und der Umfrage lässt sich folgern, dass noch zu wenig praxisrelevante Methoden entwickelt sind, die eine direkte züchterische Verbesserung der Gesundheit bringen. Es sind aber verschiedene zukunftsträchtige Methoden in Entwicklung, die praxisreif gemacht werden müssen und die auch für die Rinderzucht im ökologischen Landbau wichtig werden könnten

    Collective Action on Public Goods for Sustainable Development: Ethics in Action

    Get PDF
    Maintaining and expanding public goods is synonymous to promoting sustainable development but discussions are needed to clarify how policies need to be coordinated to enable collective action on public goods. Collective action for Public Goods will only be successful if all who partake in such actions can gain complementary benefits that would be either more costly or impossible to achieve without the collective effort

    Effects of seed predators of different body size on seed mortality in Bornean logged gorest

    Background The Janzen-Connell hypothesis proposes that seed and seedling enemies play a major role in maintaining high levels of tree diversity in tropical forests. However, human disturbance may alter guilds of seed predators including their body size distribution. These changes have the potential to affect seedling survival in logged forest and may alter forest composition and diversity. Methodology/Principal Findings We manipulated seed density in plots beneath con- and heterospecific adult trees within a logged forest and excluded vertebrate predators of different body sizes using cages. We show that small and large-bodied predators differed in their effect on con- and heterospecific seedling mortality. In combination small and large-bodied predators dramatically decreased both con- and heterospecific seedling survival. In contrast, when larger-bodied predators were excluded small-bodied predators reduced conspecific seed survival leaving seeds coming from the distant tree of a different species. Conclusions/Significance Our results suggest that seed survival is affected differently by vertebrate predators according to their body size. Therefore, changes in the body size structure of the seed predator community in logged forests may change patterns of seed mortality and potentially affect recruitment and community composition

    Eccentric endurance training in subjects with coronary artery disease: a novel exercise paradigm in cardiac rehabilitation?

    Get PDF
    This study evaluated the effects of 8weeks of eccentric endurance training (EET) in male subjects (age range 42-66years) with coronary artery disease (CAD). EET was compared to concentric endurance training (CET) carried out at the same metabolic exercise intensity, three times per week for half an hour. CET (n=6) was done on a conventional cycle ergometer and EET (n=6) on a custom-built motor-driven ergometer. During the first 5weeks of the training program the metabolic load was progressively increased to 60% of peak oxygen uptake in both groups. At this metabolic load, mechanical work rate achieved was 97 (8)W [mean (SE)] for CET and 338 (34)W for EET, respectively. Leg muscle mass was determined by dual-energy X-ray absorptiometry, quadriceps strength with an isokinetic dynamometer and muscle fibre composition of the vastus lateralis muscle with morphometry. The leg muscle mass increased significantly in both groups by some 3%. Strength parameters of knee extensors improved in EET only. Significant changes of +11 (4.9)%, +15 (3.2)% and +9 (2.5)% were reached for peak isometric torque and peak concentric torques at 60°s−1 and 120°s−1, respectively. Fibre size increased significantly by 19% in CET only. In conclusion, the present investigation showed that EET is feasible in middle-aged CAD patients and has functional advantages over CET by increasing muscle strength. Muscle mass increased similarly in both groups whereas muscle structural composition was differently affected by the respective training protocols. Potential limitations of this study are the cautiously chosen conditioning protocol and the restricted number of subject

    Synthesizing a σ^z\hat{\sigma}_z spin-dependent force for optical, metastable, and ground state trapped-ion qubits

    A single bichromatic field near-resonant to a qubit transition is typically used for σ^x\hat{\sigma}_x or σ^y\hat{\sigma}_y M{\o}lmer-S{\o}rensen type interactions in trapped ion systems. Using this field configuration, we present a novel scheme to synthesize a σ^z\hat{\sigma}_z spin-dependent force instead; this basis change merely requires adjusting the beat-note frequency of the bichromatic field. We implement this scheme with a laser near-resonant to a quadrupole transition in 88^{88}Sr+^+. We characterise its robustness to optical phase and qubit frequency offsets and demonstrate its versatility by entangling optical, metastable, and ground state qubits.Comment: O.

    Breaking the entangling gate speed limit for trapped-ion qubits using a phase-stable standing wave

    Full text link
    All laser-driven entangling operations for trapped-ion qubits have hitherto been performed without control of the optical phase of the light field, which precludes independent tuning of the carrier and motional coupling. By placing 88^{88}Sr+^+ ions in a λ=674\lambda=674 nm standing wave, whose relative position is controlled to λ/100\approx\lambda/100, we suppress the carrier coupling by a factor of 1818, while coherently enhancing the spin-motion coupling. We experimentally demonstrate that the off-resonant carrier coupling imposes a speed limit for conventional traveling-wave M{\o}lmer-S{\o}rensen gates; we use the standing wave to surpass this limit and achieve a gate duration of $15\ \mu$s, restricted by the available laser power.Comment: S.

    Secondary Prevention Through Cardiac Rehabilitation: Position Paper of the Working Group on Cardiac Rehabilitation and Exercise Physiology of the European Society of Cardiology

    Get PDF
    The purpose of this statement is to provide specific recommendations in regard to evaluation and intervention in each of the core components of cardiac rehabilitation (CR) to assist CR staff in the design and development of their programmes; the statement should also assist health care providers, insurers, policy makers and consumers in the recognition of the comprehensive nature of such programmes. Those charged with responsibility for secondary prevention of cardiovascular disease, whether at European, at national or at individual centre level, need to consider where and how structured programmes of CR can be delivered to the large constituency of patients now considered eligible for C

    Neighbourhood socioeconomic circumstances, adiposity and cardiometabolic risk measures in children with severe obesity

    Get PDF
    Background: It has recently been shown that neighbourhood socioeconomic disadvantage in childhood is associated with obesity, hypertension, fatty liver, and type 2 diabetes in adulthood. However, it is largely unknown whether neighbourhood socioeconomic circumstances are important predictors of adiposity and associated measures in children, especially in those with severe obesity. Therefore, we evaluated the associations between neighbourhood socioeconomic factors with the severity of obesity, and related cardiometabolic risk factors in a cohort of obese children.Methods: The Childhood Overweight BioRepository of Australia (COBRA) cohort study comprises 444 children (mean age 11.1 years, mean BMI z-score 2.5). Neighbourhood socioeconomic advantage/disadvantage was evaluated based on postcode information by the national Australian Socio-Economic Indexes for Areas (SEIFA) scores. Participants/parents also completed self-administered questionnaires on neighbourhood related facilities, family education and family income.Results: In analyses adjusted for age, sex and pubertal status, SEIFA indicating neighbourhood education/occupation was negatively associated with BMI, waist circumference and body fat%. Higher family education was associated with lower BMI. Neighbourhood walkability was related to lower waist circumference. Good shopping facilities in the neighbourhood were associated with increased risk of dyslipidemia and fatty liver, and the existence of parks and playgrounds nearby was related to dyslipidemia.Conclusions: The present data suggest that neighbourhood-related issues are associated with less severe adiposity among children with established obesity. Concerning cardiometabolic risk factors, shopping facilities were related to dyslipidemia and fatty liver. These findings suggest that increased awareness and efforts are needed to diminish socioeconomic inequalities between neighbourhoods.</p
