<div> <p>Phosphorus (P) is critical to our food production systems with many crop systems dependent on continual inputs to meet yield demands. However, a consequence of the widespread application of P to agricultural soils in the past 60 years has led to concerns about the long-term sustainability of P fertiliser supply and to P being transferred from soil systems to watercourses, causing diffuse pollution. This highlights the multi-scaled and interdisciplinary nature of the past, present and future of P management.  </p> </div><div> <p>The aim of this research is to define a starting framework to consider the best ways to develop a model that addresses the contemporary understanding of P processes, integrating the needs of the crop, with biogeochemical and hydrological modelling considerations, going beyond P transfer to the role of P in both food and water challenges.  </p> </div><div> <p>So, this review explores some of the current P models and the future opportunities for expanding their representation of P processes in agricultural systems. This goes beyond nesting existing models and reshapes approaches to posing research and modelling questions to achieve P models that cross disciplinary boundaries and have meaning and usability in practice. As part of this contribution, we welcome modellers and P scientists to come forward and help drive this complex issue of P in agriculture. </p> </div>

Nepal has made progress in health sciences and medical education over the past decade. We believe that there is a need in Nepal for a greater research emphasis on mixed-methods approaches, qualitative research, critical appraisal & systematic reviewing and health economics. Specifically to the discipline of epidemiology, Nepal should consider establishing more and better epidemiological studies, the kind of population-based studies that can identify risk factors, track changes over time at a population level over the decades to come.  We know how important such long-term research is but we are also painfully aware how expensive this kind on long-term research can be.DOI: http://dx.doi.org/10.3126/nje.v2i2.6572 Nepal Journal of Epidemiology 2012;2(2):179-81

Supplementing familiar linear and chronological accounts of history, we delineate a novel approach that explores connections between past, present and future. Drawing on Koselleck, we outline a framework for analysing the interconnected categories of ‘spaces of experience’ and ‘horizons of expectation’ across times. We consider the visions and anxieties of futures past and futures present; how these are constituted by, and inform, experiences that have happened and are yet to come. This conceptual frame is developed through the study of the heritage and lived experiences of a specific Victorian park within an English city. We analyse the formation of urban order as a lens to interrogate both the immediate and long-term linkages between past, present and possible futures. This approach enables us to ground analysis of prospects for urban relations in historical perspective and to pose fundamental questions about the social role of urban parks.

FIIs are companies registered outside India. In the past four years there has been more than $41 trillion worth of FII funds invested in India. This has been one of the major reasons on the bull market witnessing unprecedented growth with the BSE Sensex rising 221% in absolute terms in this span. The present downfall of the market too is influenced as these FIIs are taking out some of their invested money. Though there is a lot of value in this market and fundamentally there is a lot of upside in it. For long-term value investors, there’s little because for worry but short term traders are adversely getting affected by the role of FIIs are playing at the present. Investors should not panic and should remain invested in sectors where underlying earnings growth has little to do with financial markets or global economy.

Psychosocial stressors and social disadvantages contribute to inequalities in opportunities and outcomes. In the current paper, we use an epidemiological perspective and highlight the role stress plays on individuals by reviewing the outcomes of major stressors such as poverty and unemployment. We further analyzed the psychological and physical cost of these stressors and their long-term impact. We examined the role of universal basic income and closely looked at income experiments that were implemented in the past, in terms of their effectiveness in enhancing the community as well as individual outcomes and propose the UBI as a tool for alleviating the impact of these stressors. At a time when a major pandemic (e.g., COVID-19) threatens economic stability and health globally, we believe the UBI is relevant now, more than ever.

SummaryTo survey major developments and trends in the field of Bioinformatics in 2010 and their relationships to those of previous years, with emphasis on long-term trends, on best practices, on quality of the science of informatics, and on quality of science as a function of informatics.A critical review of articles in the literature of Bioinformatics over the past year.Our main results suggest that Bioinformatics continues to be a major catalyst for progress in Biology and Translational Medicine, as a consequence of new assaying technologies, most predominantly Next Generation Sequencing, which are changing the landscape of modern biological and medical research. These assays critically depend on bioinformatics and have led to quick growth of corresponding informatics methods development. Clinical-grade molecular signatures are proliferating at a rapid rate. However, a highly publicized incident at a prominent university showed that deficiencies in informatics methods can lead to catastrophic consequences for important scientific projects. Developing evidence-driven protocols and best practices is greatly needed given how serious are the implications for the quality of translational and basic science.Several exciting new methods have appeared over the past 18 months, that open new roads for progress in bioinformatics methods and their impact in biomedicine. At the same time, the range of open problems of great significance is extensive, ensuring the vitality of the field for many years to come.

<p><em>This study adopted the theoretical framework of narrative mediation to investigate a storied conflict talk between a landlord and her tenant in which the mediator played the role of a story recipient in the co-construction of stories with disputants. The focus of this research is on the function of questions posed by the mediator in the production of turning points which are favourable to the evolution of “better-formed” stories. The results of this study indicate that there are at least two types of questions mediators ask: 1) the questions that can help disputants reflect on their imperfectness; 2) the questions that awaken disputants’ memories of their good stories from the past. It is shown that the de-legitimacy for Self laid a foundation for the production of a good story towards a meaningful outcome for the mediation. The inadequacy of the context formed by first having legitimacy for Other followed by the de-legitimacy for Self led to the failure of destabilizing the problematic story in the mediation. The lack of the dominant party’s legitimacy for Other resulted in the absence of legitimacy from the marginalized side and would likely cause unfavourable consequences to the mediation in the long term.</em></p>

After excessive cutting in Swiss mountain forests and extirpation of most of the wildlife during the past centuries, efficient forestry and hunting laws allowed a wide regeneration of the forests and a rapid increase of ungulate populations in the present century. As a consequence, the impacts of ungulates on the vegetation became obvious. Regeneration of forest trees, however, is influenced not only by ungulates, but by a number of physical site factors and biotic impacts. As these impacts and their interactions vary extensively, regeneration is neither spatially nor temporally constant. Most of the presently used tree-regeneration methods, however, assume constant conditions, which renders a proper evaluation of tree regeneration in mountain forests and the role of ungulates impossible. Furthermore, the effect of this variation on forest development and forest functions is unknown with regard to the long term. While society requires a multipurpose mountain forest, structured at a small scale, wild ungulates use their habitat at a larger scale. This often leads to conflicts. Consequently,solutions including different scales are necessary. A lack of knowledge will, therefore, have to be met by research making data available to the practice as well as through coordinated investigations and experiments.

  Most epidemiological studies focus on the direct causes of diseases while wider, social causal factors are ignored. This paper briefly highlights the history of major epidemics and the role of Anthropocene and Capitalocene for the emergence and reemergence of pandemics like COVID-19. Books, journal articles, and statistics offer information that can explain the phenomena. A historical inquiry can inform us about the fundamental causes of pandemics. Human security and ecology are intertwined, and the global effect of pandemics responded to at the national level is inadequate. The lessons from the past and present help us devise effective ethically and socially appropriate strategies to mitigate the threats. If the present crisis is not taken seriously at the global level, the world has to face more difficult challenges in years to come.

This chapter discusses the role of corporate universities in the field of higher education and the impact of the same on conventional or traditional universities and their corresponding business schools. This chapter also proposes some strategic actions for the traditional universities to pursue in order to maintain competitive advantage over the emerging corporate universities. Some of these strategic actions include promoting and developing strong long-term and multipurpose strategic alliances with the industry, government institutions, and community development groups. Collaborative strategies are better than competitive behavior in terms of long-term benefits and costs associated with each of these strategies. Moreover, being in the forefront of learning innovation and knowledge management combined with the provision of high quality education and trainings through innovative, diverse, and flexible academic and training programs will help the traditional universities to remain the main supplier of knowledge in times to come.
