Electrical energy is one of the most important components in the development of an area. The development of sustainable development accompanied by rapid technological advances and an increase in living standards can cause the consumption of electrical energy to continue to increase, including in West Sumatra Province. To meet the needs of electrical energy in the future, it is necessary to build and develop the existing electrical system at PT. PLN (Persero) in order to serve the needs of electrical energy in the future. One of them is by predicting or predicting the demand for electrical energy in the next few years by utilizing historical data on the consumption of electrical energy in the past. In this study, the authors predict the electricity needs of West Sumatra Province from 2019 to 2028. The need for electrical energy tends to increase from year to year. In 2019 the need for electrical energy is 3,705 GWh, while in 2028 it is 6,980 GWh with an average growth in energy sales of 7.29 percent. The household sector has the highest demand for electrical energy in 2028, namely 3,769 GWh with an average percentage increase per year of 6.6 percent. Keywords: Power system planning, Electrical energy consumption, Generation planning and Electrification ratio.

One of the central questions in international relations today is how we should conceive of state sovereignty. The notion of sovereignty—’supreme authority within a territory’, as Daniel Philpott defines it—emerged after the Treaty of Westphalia in 1648 as a result of which the late medieval crisis of pluralism was settled. But recent changes in the international order, such as technological advances that have spurred globalization and the emerging norm of the Responsibility to Protect, have cast the notion of sovereignty into an unclear light. The purpose of this paper is to contribute to the current debate regarding sovereignty by exploring two schools of thought on the matter: first, three Catholic scholars from the past century—Luigi Sturzo, Jacques Maritain, and John Courtney Murray, S.J.—taken as representative of Catholic tradition; second, a number of contemporary political theorists of cosmopolitan democracy. The paper argues that there is a confluence between the Catholic thinkers and the cosmopolitan democrats regarding their understanding of state sovereignty and that, taken together, the two schools have much to contribute not only to our current understanding of sovereignty, but also to the future of global governance.

Cryo–electron microscopy, or simply cryo-EM, refers mainly to three very different yet closely related techniques: electron crystallography, single-particle cryo-EM, and electron cryotomography. In the past few years, single-particle cryo-EM in particular has triggered a revolution in structural biology and has become a newly dominant discipline. This Review examines the fascinating story of its start and evolution over the past 40-plus years, delves into how and why the recent technological advances have been so groundbreaking, and briefly considers where the technique may be headed in the future.

Purpose The purpose of this paper is to analyze the history and future of service operations, with the goal to identify key theoretical and technological advances, as well as fundamental themes that can help to imagine the future of service operations in 2050. Design/methodology/approach A review of the service operations literature was undertaken to inform a discussion regarding the role that technology will play in the future of service operations. Findings The future of service operations is framed in terms of three key themes – complexity, orchestration, and elasticity. The paper makes three contributions to the service science literature by: reviewing key themes underpinning extant service operations research to frame future trajectories of service operations research; elaborating a vision of service operations in 2050 based on history and technology; and outlining a research agenda for future service operations. Practical implications The case of service automation is used to provide an illustration of how the three themes converge to define future service operations, and in particular, to show how technology is recasting the role of the firm. Originality/value Service operations in the next 30 years will be very different from what it was in the past 30 years. This paper differs from other review papers by identifying three key themes that will characterize and instill new insights into the future of service operations research.

Matching individuals to tolerable and efficacious pharmacotherapies in mental health has proven challenging. As such, efforts to personalize psychotropic prescribing in mental health has received considerable attention over the past decade. This attention has been fueled by technological advances in genomics, specifically, pharmacogenomics, and, more recently, epigenomics, transcriptomics, proteomics, and metabolomics that have facilitated the identification of clinically useful biological markers to guide medication selection and dosing. The convergence of these omic technologies is arguably the future of personalized psychotropic prescribing. This chapter provides an overview of the current genomic, epigenomic, transcriptomic, proteomic, and metabolomic knowledgebase as it relates to psychotropic drug response in an effort to identify promising linkages between and facilitate convergence across these approaches to guide safe and effective pharmacotherapy relevant to psychiatry.

Abstract As economies, societies, and environments change, official statistics evolve and develop to reflect those changes. In reaction to disruptive innovations arising from globalisation, technological advances, and cultural changes, the pace of change of official statistics will accelerate in the future. The motivation for change may also be more existential than that of the past as official statisticians consider the survival of their discipline. This article examines some of the emerging developments and questions whether they present threats or offer opportunities.

History is a part of social science. In history, we can study the various events that occurred in the past that can determine what happened in the future. With this historical knowledge, we can find out the origin of these events in the past through various sources such as books, relics, etc. [R1] However, in the 21st-century history lessons are starting to be abandoned by the current generation because of the ongoing technological advances. Even though studying history is very important as a provision for carrying out life in the future. Therefore, by taking advantage of these technological advances, we can use the game Assassin's Creed which is booming lately as a way to increase interest in learning history. The purpose of writing this paper is to explain the benefits of the game Assassin's Creed as a medium to increase interest in learning history so that in this game the player not only knows the characters, the time, and the mission but also knows the storyline of this game because it is related to events that have already occurred. To achieve this goal, the article focuses on several questions about historical learning in the present and the use of one of the games to increase interest in learning. The research method used is a literature review that performs data processing and sorting according to the discussion topics discussed by the author. The data is in the form of 20 journal articles with a span of years from 2019-2021 and website 2 trusted sites. The results of this study are in the form of an explanation of historical learning in the 21st century and the game Assassin's Creed with several series that have different synopses but have links to historical events. Thus, technological advances need to be utilized positively through the use of games as a means of increasing interest in learning history.

The past 30 years have seen political surveys, particularly those related to elections, evolve from an occasional novelty to a staple feature of the Kenyan political scene. This chapter considers several issues with regard to these surveys. These include: (1) the practical challenges in conducting them as well as recent technological advances; (2) the reasons why a high level of suspicion is often attached to election polls in particular, and the main rhetorical forms that such suspicion takes; and, (3) several factors likely to affect the future of such surveys, beyond the widespread awareness of and considerable public support for them, especially the attitudes of those in, and aspiring to, power. It concludes by suggesting that the recent “proliferation” of such polls is no guarantee of their continuation.

Abstract In the quest for quick economic development, many Sub Saharan African (SSA) countries borrow money to finance their budget deficits and vital infrastructure. Niger has seen its external debt increase year after year without really reaching economic development. This study uses a vector autoregressive (VAR) model to investigate the relation linking external debt and economic growth in Niger and variance decomposition forecast to verify if there is any significant impact from shocks for a period of 5 years in the future. The study utilises time series yearly data provided by the World Bank for the period covering 1970–2019. The empirical results reveal no long-run relationship between economic growth, external debt and government spending in Niger. The results also indicated that, on average ceteris paribus, the past realisation of economic growth is related to an increase of 97.75 % in economic growth, while the past realisation of external debt and government spending is associated with an increase of 83.77 % and 79.70 % in external debt and government spending, respectively. The results furthermore show that economic growth has a statistically significant causal effect on government spending in the short term. One percentage increase in economic growth accounts for an increase of 35.28 % in government spending on average ceteris paribus. The variance decomposition forecast reveals that economic growth has a significant influence on predicting government spending in the future.

I did not really want to write an article about something which is as yet unfinished, but, since this project is based upon principles common to the design of many features of my intensive care unit, principles which I think should be borne in mind when designing units for the future, I think that it is worth describing the evolution of the project so far. The very rapid technological advances of the past couple of decades have produced a plethora of gadgets for monitoringphysiological systems and for boosting or replacing defective systems. Many patients owe their lives to artificial ventilation, artificial kidneys, etc. We have become very ambitious in our treatment of life threatening acute illness and are tackling patients with multi-system failure who would have simply been allowed to die twenty years ago. Unfortunately all advances bring new problems.

Various academic disciplines shed light on human migrations, helping us to reconstruct the past. Studying the genetic diversity of human populations today reveals past demographic and migratory events that have left an imprint on our genome. Armed with knowledge of migrations in prehistoric times, we can test hypotheses put forward in other scientific disciplines. Similarly, the distribution of genetic diversity in the future will largely depend on today’s extensive human migrations, facilitated by technological advances.
