The Moment

The aim of the essay is to analyse a special moment, namely the moment of the end of a tyranny. An outstanding problem is how to judge the murder of a tyrant, and the occurrences that lead to that, because these acts actually make a chain of crimes, if they’re examined without the context. Breach of the peace, mayhem, mutiny, homicide, these are acts, that are against the moral code of humanity. They have been punished by criminal laws throughout history. Therefore it is crucial to examine the circumstances of this very act. These circumstances are actually the key factors to legitimise the aggression of a rebellion. Nevertheless the first thing that someone has to do during the analysis is to find a comprehensive definition that shows who is the person, who possesses the characteristic of an unjust despot.

The Impact

Health supply chains aim to improve access to healthcare, and this can be attained only when health commodities appropriate to the health needs of the global population are developed, manufactured, and made available when and where needed. The weak links in the health supply chains are hindering the access of essential healthcare resulting in inefficient use of scarce resources and loss of lives. A chain is only as strong as its weakest link, and demand forecasting is one of the weakest links of health supply chains. Also, many of the existing bottlenecks in supply chains and health systems impede the accurate forecasting of demand, and without the ability to forecast demand with certainty, the stakeholders cannot plan and make commitments for the future. Forecasts are an important feeder for budgeting and logistics planning. Under this backdrop, the study examines how improved forecasting can lead to better short-term and long-term access to health commodities and outlines market-related risks. It explores further how incentives are misaligned creating an uneven distribution of risks, leading to the inability to match demand and supply. For this purpose, a systematic literature review was performed, analyzing 71 articles from a descriptive and content approach. Findings indicate the emerging trends in global health and the consequences of inaccurate demand forecasting for health supply chains. The content analysis identifies key factors that can pose a varying degree of risks for the health supply chain stakeholders. The study highlights how the key factors emerge as enablers and blockers, depending on the impact on the overall health supply chains. The study also provides recommendations for actions for reducing these risks. Consequently, limitations of this work are presented, and opportunities are identified for future lines of research. Finally, the conclusion confirms that by adopting a combination of approaches, stakeholders can ensure better information sharing, identify avenues of diversifying risks, and understand the implications.

The precision of transferring paper is key factors to decide the print overprint accuracy, and vibration has an important impact on paper transferring accuracy. Empirical mode decomposition (EMD) can be used to extract the features of vibration test signal. According to the intrinsic mode function (IMF) by extracted, it is useful to analyze the dynamic characteristics of swing gripper arm on motion state. Due to the actual conditions of printing, the vibration signal of Paper-Transferring mechanism system is complex quasi periodic signals. Hilbert-Huang marginal spectrum that is based on empirical mode decomposition can solve the problem which is modals leakage by FFT calculated in frequency domain. Through the experimental research, the phase information of impact load at the moment of grippers opening or closing, which can be used for the optimization design of Paper-Transferring system and the improvement in the accuracy of swing gripper arm.

This paper presents the design and analysis of an underactuated, cable driven mechanism for use in a modular robotic snake. The proposed mechanism is composed of a chain of rigid links that rotate on parallel revolute joints and are actuated by antagonistic cable pairs and a multi-radius pulley. This design aims to minimize the cross sectional area of cable actuated robotic snakes and eliminate undesirable nonlinearities in cable displacements. A distinctive feature of this underactuated mechanism is that it allows planar serpentine locomotion to be accomplished with only two modular units, improving the snake’s ability to conform to desired curvature profiles and minimizing the control complexity involved in snake locomotion. First, the detailed mechanism and cable routing scheme are presented, after which the kinematics and dynamics of the system are derived and a comparative analysis of cable routing schemes is performed, to assist with design synthesis and control. The moment of inertia of the mechanism is modeled, for future use in the implementation of three-dimensional modes of snake motion. Finally, a planar locomotion strategy for snake robots is devised, demonstrated in simulation, and compared with previous studies.

✓ Acute subarachnoid hemorrhage (SAH) and intraparenchymal hematoma (IPH) in cats are accompanied by massive cellular depolarization. This depolarization, characterized by potassium (K+) efflux and calcium (Ca++) influx, results in membrane destabilization, osmotic imbalance, and a decrease in electrical conduction. The Ca++ influx appears to initiate a chain reaction that, in some instances, may result in delayed cell destruction. The ionic dysequilibrium probably contributes to both brain engorgement and spasm in large vessels. The cellular depolarization and calcium-induced cell membrane injury at the moment of impact may play a greater role in the pathophysiology of head trauma than previously thought.

Fundamental Reference

According to dominant theorizations of contemporary society, many people’s daily practices now occur within, and reproduce, a social world where media are the fundamental reference and resource for the development of the self (Couldry and Hepp 2017:15). Although previous research has revealed the mutual shaping of technologies, interaction, and identity in the broader contexts of economic and social change related to ‘millennials’, we know little about the precise ways in which these practices occur and how the self is being differently constructed over time. Using a multi-method qualitative approach, this work in progress paper explores three key questions: 1) What happens when visuality becomes a part of youth’s everyday practices of interaction? 2) What roles are images playing in routine interaction among youth? 3) How and in what ways does the maintenance of a visually ‘mediated presence’ in social media shape youths’ views of the self? This paper elaborates on findings within three categories that illustrate youth’s visual practices and how they are differently understood over time: (1) images of the self in the moment; (2) images of the self over time; and (3) images of the self under surveillance. The preliminary findings of this research suggest that although youth’s technological practices may not all be new, there are significant aspects of visuality that alters some of the key factors shaping young people’s use and understandings of new media technologies.

Comprehensive Study

Estimation of efficiency from the perspective of an external investor draws a high enough interest in assessing the efficiency of risk management. Since the methods risk management are nontransparent information, the carrying out of empirical research is enough complicated. However, in a number of papers the elements of the assessment of so-called "market efficiency" are traceable, among which the most common factors are: the behavior of stock prices at the moment of collapse of the market, lower average cost of capital. However, a comprehensive study on risk management efficiency of companies from the perspective of stakeholders has not yet provided. The aim of this study is to fill this gap. The purpose of this study is as follows: to identify how stakeholders assess the key factors of risk management efficiency, and to create a comprehensive approach to the implementation of this assessment with the using of statistical research techniques and methods. The object of study is the Russian real sector of economy, the subject of study is the risk management efficiency of companies. In this article author provides the results of the survey on the evaluation the risk management efficiency, processed by means of statistical analysis methods calculation of the actual ratings of Russian companies on the basis of the criteria obtained from the survey, as well as the results of the regression analysis of the impact of identified efficiency criteria of risk management on the investment attractiveness of Russian companies. In the article Russian companies are ranked based on their risk management efficiency.

International audience We analyze on-line chain partitioning problem and its variants as a two-person game. One person (Spoiler) builds an on-line poset presenting one point at time. The other one (Algorithm) assigns new point to a chain. Kierstead gave a strategy for Algorithm showing that width w posets can be on-line chain partitioned into $\frac{{5}^{w-1}}{4}$ chains. Felsner proved that if Spoiler presents an upgrowing poset, i.e., each new point is maximal at the moment of its arrival then there is a strategy for Algorithm using at most $\binom{w+1}{2}$ chains and it is best possible. An adaptive variant of this problem allows Algorithm to assign to the new point a set of chains and than to remove some of them (but not all) while covering next points. Felsner stated a hypothesis that in on-line adaptive chain covering of upgrowing posets Algorithm may use smaller number of chains than in non-adaptive version. In this paper we provide an argument suggesting that it is true. We present a class of upgrowing posets in which Spoiler has a strategy forcing Algorithm to use at least $\binom{w+1}{2}$ chains (in non-adaptive version) and Algorithm has a strategy using at most $O(w\sqrt{w})$ chains in adaptive version.

There are times when technological or scientific progress is blocked for want of a breakthrough in a key area, just as there appear to be instances of a problem and its solution emerging simultaneously and independently. Upon closer inspection, however, this latter happy state is usually the result of long, hard work by people who had the insight to develop a solution before their peers were aware of the existence of a problem. At the moment, there are a number of convergent events occurring in vacuum technology which in all likelihood will have as profound an effect as the development of ultrahigh vacuum (UHV) technology in the late 1960s and early 1970s. These developments may be viewed as challenges posed by the requirements of certain technologies, or as a series of breakthroughs which will lead to new opportunities. Materials and materials processing or coatings are the key factors in most of these new developments, just as new pump and seal designs, and new vacuum practice were responsible for the development of UHV (10−9–10−11 torr) technology.In particular, aluminum is emerging as a material which may replace stainless steel for applications where the ultimate in vacuum is required. By suitable treatment, pure aluminum and aluminum alloys can be made to produce static outgassing rates more than 10 times lower than stainless steel. Systems capable of reaching a base pressure in the extremely high vacuum (XHV) range of 10−12–10−13 torr, such as those described in this issue by H. Ishimaru, are now commercially available.

AbstractBackground/Aim. Early diagnosis and adequate surgical treatment are the key factors for the course of the laryngeal cancer of the head and neck and the outcome of the surgical treatment in these patients. The aim of the paper is to compare the characteristics of the surgically treated patients with the larynx carcinoma who developed recidivism to those who did not.Material and methods. The study was done as a retrospective observational case-control study on a total of 90 patients with the laryngeal cancer who had been successfully operated on and whose cases had been followed over a period of at least five years after the surgery. After that, they were shorted into two groups based on the development of recidivism, and clinical characteristics of the patients with and without recidive disease were compared.Results. 19 out of 90 patients developed recidivism. Maximum diameter of the tumour was significantly larger in patients without local recidivism. In patients without local recidivism, most common clinical stages were 3 and 4 (32.4%, 40.8%, respectively), whereas in patients with local recidivism stages 1 and 2 were the most common (47.7%, 26.3%, respectively). The average time to disease recurrence in the 19 patients who developed local recidive disease was 648.10 (384.67-911.54) days.Conclusion. Pathohisto-logical analysis showed that samller the size of the tumour and lower T grade at the moment of surgery are precautionary factors for further monitoring of patients with laryngeal cancer.

<p>Exploring the past, and pulling ideas through to the present, to inform the future can make a valuable contribution to nurses and nursing in New Zealand. By gaining some understanding of the attitudes and beliefs nurses held, and how these influenced their responsiveness, we can learn what active responses might help inform our future. Nurses in New Zealand, as individuals and within the profession as a whole, reveal the primacy of the nurse – nurses who have made and can continue to make a difference to the health of the peoples of New Zealand. A hermeneutic process was used to interpret material, from international texts, national texts and public records over four decades, the 1960s to 1990s. This was supplemented and contrasted with material from twelve oral history participants. Analysis of the material led to the emergence of four themes: Nurses’ decision-making: changes over time; An emerging understanding of autonomy and accountability; Nurses as a driving force; and Creating a nursing future. These four themes revealed an overall pattern of attitudes, beliefs and responses of the New Zealand Registered Nurse. The themes surfaced major revelations about the primacy of the nurse in New Zealand, nurses confident in their ability to take the opportunity, seize the moment, and effect change. The contribution this thesis makes to the discipline of nursing is an understanding of how the nurse actively constructs the scope of a professional response to the context. The thesis demonstrates how nurses can learn from the past, that the attitudes and beliefs that underpin our active responses can either move us forward, or retard our progress. As nurses we can also learn that to move forward we need particular attitudes, beliefs and responses, that these are identifiable, and are key factors influencing our future, thus ensuring the continued primacy of the nurse.</p>
