State Management

Explore global state management and select the best library for your application Key Features Understand the essential concepts and features of micro state management Discover solutions to common problems faced while implementing micro state management Explore the different libraries, their coding style, and the optimum approach to rendering optimization Book Description State management is one of the most complex concepts in React. Traditionally, developers have used monolithic state management solutions. Thanks to React Hooks, micro state management is something tuned for moving your application from a monolith to a microservice. This book provides a hands-on approach to the implementation of micro state management that will have you up and running and productive in no time. You'll learn basic patterns for state management in React and understand how to overcome the challenges encountered when you need to make the state global. Later chapters will show you how slicing a state into pieces is the way to overcome limitations. Using hooks, you'll see how you can easily reuse logic and have several solutions for specific domains, such as form state and server cache state. Finally, you'll explore how to use libraries such as Zustand, Jotai, and Valtio to organize state and manage development efficiently. By the end of this React book, you'll have learned how to choose the right global state management solution for your app requirement.

Although Indonesia is generally considered to be a Muslim state, and is indeed the world’s most populous Muslim-majority nation, it has a sizeable Christian minority as a legacy of Dutch colonialism, with Christians often occupying relatively high social positions. This book examines the management of religion in Indonesia. It discusses how Christianity has developed in Indonesia, how the state, though Muslim in outlook and culture, is nevertheless formally secular, and how the principal Christian church, the Java Christian Church, has adapted its practices to fit local circumstances. It examines religious violence and charts the evolution of the state’s religious policies, analysing in particular the impact of the 1974 Marriage Law showing how it enabled extensive state regulation, but how in practice, rather than reinforcing religious divisions, inter-religious marriage, involving the conversion of one party, is widespread. Overall, the book shows how Indonesia is developing its own brand of secularism, neither a full-blooded Islamic state like Saudi Arabia, nor an outright secular state like Turkey.

State Management offers a comprehensive yet concise introduction to the new field of state management, presenting an analysis of basic questions within the theories of bureaucracy, policy-making, principal-agent modelling and policy networks. Focussing upon recent state transformation, it illuminates public sector reform strategies such as New Public Management as well as incorporation, tendering and bidding, decentralization, team production and privatization. This book argues that we should look upon the variety of models or approaches to public management or public administration as all belonging under "state management". The so-called "working state" in a well-ordered society involves government delivering services, paying for social security and respecting the rule of law. In this text, Jan-Erik Lane systematically examines the key approaches to the study of how government attempts to achieve these goals, discussing the pros and cons of alternative frameworks of analysis. Each chapter discusses a different issue within state management that is integral to the broader debate, including: Public regulation The relationship between the law and the state Combining ecology and policy making Multi-level governance The virtues and vices of public-private partnerships Policy implementation Presenting a clear overview of how the state operates when government sets out to deliver public services, and generating questions to encourage new research, State Management is a valuable new text for both undergraduate and postgraduate courses in political science, public administration and public management.

What GAO Found GAO's analysis of the overseas real property portfolio of the Department of State (State) indicates that the overall inventory has increased in recent years. State reported that its leased properties, which make up about 75 percent of its inventory, increased from approximately 12,000 to 14,000 between 2008 and 2013. State's numbers of federally owned properties increased, but comparing the total number of owned properties from year to year can be misleading because State's method of counting these properties has been evolving over the past several years. Specifically, according to State officials, they have been revising their method for counting properties to produce more precise counts and to meet reporting guidance from the Office of Management and Budget (OMB), among others. For example, State began counting separately structural assets previously included as part of another building's assets, such as guard booths or perimeter walls, and consequently reported approximately 650 additional structural assets in fiscal year 2012 than in 2011, and approximately 900 more structures in 2013. State officials told GAO that they consider many factors in managing real property; however, GAO found State's available data and documentation on management decisions were limited. State officials said that they work with overseas posts to identify and dispose of unneeded properties, primarily using factors in State's Foreign Affairs Manual ( FAM ) guidance. Such factors include identifying properties deemed obsolete or with excessive maintenance costs. State collects data on costs associated with unneeded properties identified for disposal, relying on posts to charge all such costs to a specific accounting code. The four posts GAO visited did not use this code consistently. For example, officials at one post charged some disposal costs to a routine maintenance account. Officials at the other posts with properties for sale used the code to charge all related disposal costs. GAO also found that other posts with unneeded properties identified for disposal in fiscal year 2013 had not charged expenses to this account. The guidance provided in the FAM for using this code does not detail the types of costs that can be charged. This omission raises questions about the extent to which posts use the code as State intends and the extent to which State receives accurate and comprehensive cost information about its unneeded properties. State, without accurate data on unneeded property, may not have the information it needs to make a decision about property offers when attempting to maximize revenue for property sales. Also, posts may not have sufficient funding for routine property maintenance if they use funds designated for this type of maintenance on unneeded property. GAO requested to review 202 files between fiscal year 2008 through 2013 on acquisitions (72), disposals (94), and leases (36), but was provided 90, as State told GAO that these files were not centrally located and too time consuming to find and provide during the time frame of our review. State provided most of what it considers “core” documents for the acquisition and disposal files, but these documents do not constitute all of the documentation listed in the FAM and OMB guidance. In addition, although State provided all 36 of the requested lease files, some documentation that State agreed to provide was missing for 30 of the 36 files. Without the missing files and documentation, it is unclear how efficiently and effectively State is managing its overseas real property. Why GAO Did This Study The Department of State (State) holds or leases about 70-million square feet of real estate in about 275 posts worldwide and has the authority to construct, acquire, manage, and dispose of real property abroad. GAO was asked to review State's management of overseas real property. This report examines: (1) what is known about State's overseas real property inventory, and (2) what factors State considers in managing its overseas real property portfolio and to what extent it documents its decision-making process pertaining to real property. GAO requested 202 files for all acquisitions, disposals, and major leases pertaining to State's management of its real property abroad for the period from 2008-2013. In addition, GAO interviewed State officials in headquarters and at four posts abroad, selected because they had (1) ongoing or recently completed embassy construction or renovation projects without property disposals, (2) properties reported as identified for disposal for multiple years without being disposed, and (3) both owned and leased properties. The results of the four case studies cannot be generalized for the purpose of this review. What GAO Recommends GAO recommends that the Secretary of State (1) clarify accounting code guidance for tracking expenses related to disposal of unneeded properties, and (2) take steps to collect and retain documents related to real property purchases, disposals, and leases in accordance with the FAM and OMB's guidance. State concurred with GAO's recommendations.
