To assess the role of cyclone tracks in contributing to floods and droughts, we highlight the role of midlatitude cyclones played in the 1988 drought and the 1993 flood. Our results demonstrate that the 1988 drought featured a poleward-displaced cyclone track with a reduced role for cyclone-induced precipitation, especially in the spring of 1988. The 1993 flood featured a cyclone track from Mexico northeast to Missouri in the spring, while the summer featured two cyclone tracks: one in the southwestern US and the other across Canada linked to the right-entrance and left-exit regions of a strong 200 hPa Jetstream across the upper Midwest. Enhanced 850 hPa inflow from the Caribbean northeast to the Midwest with high precipitable water values occurred in conjunction with the right entrance portion of the 200 hPa Jetstream. Linking storm tracks and the 200 hPa Jetstream to a storm-rain index for the Midwest showed that these extreme events conformed to features of the general circulation normally associated with wet/dry episodes in the warm half of the year. Although El Niño did not play a role in the 1993 flood, the 1988 drought was associated with a poleward displacement of cyclone tracks in response to La Niña.

This article deals with the impact of various factors on the perception of Russia in different European countries. The focus is on the role of mass media, expert and political elites in forming of Russia's image, especially in the context of Ukrainian crisis. In this article, the reaction of different European counties to events in Ukraine, the polarization of European space is analyzed: some countries prefer to put a pressure on the Russian Federation, other – to find a way out of the critical situation and reach a compromise. Some political establishment representatives in France, Germany, Czech Republic support Russia and the reunification with Crimea, dispute sanctions against Russia. For such politicians, this support results from anti-American views and independent foreign policy aspirations. Other representatives of the European elite demand tougher approach and more pressure on Russia by any means whatsoever (including military ones). European business-communities reveal great interest in solving issues related to sanctions. Many entrepreneurs in Europe (in particular major corporations in France, UK, Germany, Italy), who profit from long and fruitful cooperation with Russia, are against anti-Russian sanctions. In view of the Ukrainian crisis, Russia has to face and solve various important issues. How can Russia implement a modernization project after burning all traditional bridges to the West and western friends and partners? What is the right way for Russian foreign policy to support and defend Russian-speaking people all over the world? Which European political forces can provide support to Russia? How can civil society affect and influence cooperation between Russia and Europe?

This case note focuses on the justiciability as well as the impact of corruption on the realisation of the right to basic education. Through an assessment of the decision of the ECOWAS Court in SERAP v. Nigeria, it emphasises the role of states in ensuring that corrupt activities of government officials or third parties do not affect the enjoyment of the right. It equally emphasises the role of the Nigerian courts in ensuring a justiciable right to education.

<p><span>We investigate the impact of air-sea coupling on the simulation of the intraseasonal variability of rainfall over the South Pacific using the ECHAM5 atmospheric general circulation model coupled with Snow-Ice-Thermocline (SIT) ocean model. We compare the fully coupled simulation with two uncoupled simulations forced with sea surface temperature (SST) climatology and daily SST from the coupled model. The intraseasonal rainfall variability over the South Pacific Convergence Zone (SPCZ) is reduced by 17% in the uncoupled model forced with SST climatology and increased by 8% in the uncoupled simulation forced with daily SST. The coupled model best simulates the key characteristics of the two intraseasonal rainfall modes of variability in the South Pacific, as identified by an Empirical Orthogonal Function (EOF) analysis. The spatial structure of the two EOF modes in all three simulations is very similar, suggesting these modes are independent of air-sea coupling and primarily generated by the dynamics of the atmosphere. The southeastward propagation of rainfall anomalies associated with two leading rainfall modes in the South Pacific depends upon the eastward propagating </span><span>Madden-Julian Oscillation (</span><span>MJO</span><span>)</span><span> signals over the Indian Ocean and western Pacific. Air-sea interaction seems crucial for such propagation as both eastward and southeastward propagations substantially reduced in the uncoupled model forced with SST climatology. Prescribing daily SST from the coupled model improves the simulation of both eastward and southeastward propagations in the uncoupled model forced with daily SST, showing the role of SST variability on the propagation of the intraseasonal variability, but the periodicity differs from the coupled model. The change in the periodicity is attributed to a weaker SST-rainfall relationship that shifts from SST leading rainfall to a nearly in-phase relationship in the uncoupled model forced with daily SST.</span></p>

This chapter examines both the power and limitations of litigation as a means of facilitating accountability for the advancement of public health. While almost half of the world’s constitutions now contain a justiciable right to health, the impact of litigation has been mixed. Judicial accountability has, in some cases, advanced state obligations to realize the highest attainable standard of health, but in other cases, litigation has threatened the solidarity undergirding public health systems. There is significant country-to-country variation in interpreting health-related human rights, as well as differing views of the proper role of courts in interpreting and enforcing these rights. Surveying regional human rights systems and national judicial efforts to address health and human rights, it is necessary to analyze how courts have approached—and how they should approach—litigation of the right to health and health-related human rights to improve health for all.

<p>Extratropical cyclones are the leading driver of the day-to-day weather variability and wintertime losses for Europe. In the latest generation of coupled climate models, CMIP6, it is hoped that with improved modelling capabilities come improvements in the structure of the storm track and the associated cyclones. Using an objective cyclone identification and tracking algorithm the mean state of the storm tracks in the CMIP6 models is assessed as well as the representation of explosively deepening cyclones. Any developments and improvements since the previous generation of models in CMIP5 are discussed, with focus on the impact of model resolution on storm track representation. Furthermore, large-scale drivers of any biases are investigated, with particular focus on the role of atmosphere-ocean coupling via associated AMIP simulations and also the influence of large-scale dynamical and thermodynamical features.</p>

Abstract The impact of South American orography on subtropical stratocumulus clouds off the Peruvian coast is investigated in the context of an atmospheric general circulation model. It is found that stratocumulus incidence is significantly reduced when South American orography is removed. Key to this behavior is a decrease in lower tropospheric stability (LTS) that allows for more frequent stratocumulus destruction through the model’s cloud-top entrainment instability mechanism. The role of orography in enhancing Peruvian stratocumulus is as follows. Within the PBL, orography deflects the midlatitude westerly winds equatorward in association with cold air advection and blocking of the low-level flow from the continent. Above the PBL, the steep and high South American orography deflects a significant portion of the midlatitude westerlies equatorward. This flow sinks along the equatorward sloping isentropes, thus promoting subsidence. Both processes increase LTS over the stratocumulus region. In further AGCM experiments, the sensitivity of Peruvian stratocumulus to the use of unsmoothed orographic boundary conditions is assessed. The results show no significant differences to the control simulation, which uses smoothed orography. This suggests that, in the context of GCMs, a representation of South American orography more detailed than is generally used has little potential for improving the performance of coupled ocean–atmosphere models in the eastern tropical Pacific.

AbstractThe essay focusses on the employment relationship as a privileged perspective for the analysis of the binomial “power of voices/voices of power.” In such context, the right to strike is presented as a meaningful example of the power stemming from a collective organisation of voices, the voices of the workers, granted as a means to counter-balance the power and the voice of the employer. The analysis highlights the enduring relevance of the British perspective towards the topic, from the liberalist policies fostered by Prime Minister Thatcher in the Eighties until the critical approach recently adopted by the British Government with regard to the protection of the right to strike at international level. British filmography is chosen as a lens for observing such perspective, in particular to the extent it describes the impact of Thatcherism on the British model of industrial relations as well as the economic and social consequences of such political measures in the Nineties. After a general overview, aimed at highlighting common features across the films, like the pivotal role of music and dance in the storyline, the analysis focusses on Billy Elliot, examining the ambiguous relationship between the collective and individual dimension in its narration.

AbstractThis monograph investigates the development of the right to water (RtW) and of water law in the Latin American context. Specifically, it examines the significance of Latin American (la) constitutional evolution, doctrine, and jurisprudential contribution in stimulating the social, political, and economic debate on the RtW, regionally and worldwide. Firstly, an overview on the RtW inlaconstitutions is provided and the impact of the findings is highlighted. The mainlawater management systems are then reviewed with an acknowledgment that an analysis of the RtW has to take account of its application in specific contexts. The intrinsic connection between the RtW and the role of the private sector is examined through specific insights into the highly privatized Chilean water services. Lessons learnt from thelaexperience are outlined in the conclusion and their relevance for the global debate on the RtW is illustrated.

This article examines the impact of Freud on conservative liberal intellectuals in America particularly during the Cold War. It argues that, compared with studies of the ‘radical’ or left-wing assimilations of psychoanalysis, the Freud of the political Right has been relatively neglected. It concentrates on three figures in particular – Irving Kristol, Norman Podhoretz and Leo Strauss, all of whom were a major influence on the formation of American neoconservatism, and ultimately on the Bush administration at the time of the War on Terror. The article also examines the role of Lionel Trilling in mediating Freudian ideas to Kristol and Podhoretz, who were disaffected with the progressive aspects of liberalism, and shifted their allegiance to the Right by the 1980s. Freud's work, especially Civilization and its Discontents, functions as an ideological landmark at the borderline of their reflections on religion, morality, the failures of democracy and the foundations of social order.

PurposeIn recent years, and especially during the coronavirus disease 2019 (COVID-19) pandemic, the significant role of agriculture, specifically red meat, in household consumption has been increased. On the other hand, the lack of proper policymaking in the production and pricing of red meat and the lack of a comprehensive study on the beef supply chain has led to a reduction in the role of this protein product in the household food basket. Thus, in this research, comprehensive strategic planning considering the effect of the COVID-19 pandemic has been illustrated to overcome the aforementioned problems.Design/methodology/approachTo study the intended objectives, first, using qualitative methods, the strengths, weaknesses, opportunities and threats (SWOT) to the studied company's supply chain in Iran were identified and then using the SWOT-Quantitative Strategic Planning Matrix (QSPM) technique, the surrounding strategies have been analysed.FindingsThe results indicate that the most important strength of the studied company is the “access to the red meat market of the retirement plan”; the most important weakness is the “lack of required and on-time funding, especially in the condition of the COVID-19 pandemic”; the highest-ranked opportunity is the “access to banking facilities” and the main threat to the company is the “COVID-19 pandemic limitations and health protocols”. In the same vein, by examining the attractiveness score of internal and external factors, it was observed that diversity and competitive strategies would have a higher priority. Finally, the QSPM illustrated that activating the full capacity of existing infrastructure has the highest priority.Originality/valueAccording to the red meat supply chain and the link amongst different market levels, identifying, analysing and improving the beef supply chain is of particular importance. One of the threats facing the international community is the emergence of events such as the COVID-19 pandemic, which requires businesses to choose the right strategy to deal with the issue. Therefore, the main distinction of this study is to identify, analyse and improve the red meat supply chain of a real case due to the condition of the COVID-19 pandemic.
