Abstract:

This paper discusses issues that will affect the future development of the Web, either increasing its power and utility, or alternatively suppressing its development. It argues for the importance of the continued development of the Linked Data Web, and describes the use of linked open data as an important component of that. Second, the paper defends the Web as a read–write medium, and goes on to consider how the read–write Linked Data Web could be achieved.

Abstract:

Leaderless replication allows any replica to handle any type of request to achieve read scalability and high availability for distributed data stores. However, this entails burdensome coordination overhead of replication protocols, degrading write throughput. In addition, the data store still requires coordination for membership changes, making it hard to resolve server failures quickly. To this end, we present NetLR, a replicated data store architecture that supports high performance, fault tolerance, and linearizability simultaneously. The key idea of NetLR is moving the entire replication functions into the network by leveraging the switch as an on-path in-network replication orchestrator. Specifically, NetLR performs consistency-aware read scheduling, high-performance write coordination, and active fault adaptation in the network switch. Our in-network replication eliminates inter-replica coordination for writes and membership changes, providing high write performance and fast failure handling. NetLR can be implemented using programmable switches at a line rate with only 5.68% of additional memory usage. We implement a prototype of NetLR on an Intel Tofino switch and conduct extensive testbed experiments. Our evaluation results show that NetLR is the only solution that achieves high throughput and low latency and is robust to server failures.

Abstract:

Traditional file systems have some shortages in storing small files, such as randomness of data layout, waste of disk space and lack of inode resources. In this thesis, a log-structured file system named LevelFS based on LevelDB is presented. By setting the write buffer, it can make disk randomized writes of small files into disk sequential writes, and reduce the distance of related data, so as to improve the read and write performance of file system. Experiments show that LevelFS can greatly improve read and write performance of small files without affect the large ones.

Abstract:

This paper designed method for non-volatile data storage using MCU internal data Flash, certain data Flash sector is divided into multiple data partitions, different data partition storage data copies in different historical time, the current data partition storagethe latest copy of the data; In the data read operation, first calculate the latest data copying Flash storage location, then directly reads the address. In the data write operation, first judge if the data writing position is already erased, if not,write data in next partition, while copy the other data in the current partition to the next partition; if the write position has been erased, write data directly to the current partition. This method is similar to EEPROM data read and write, easy to operate, and give a simple application interface, and can avoid the sector erase operation, to improve storage efficiency, while increasing the service life of the MCU's internal data Flash.

Abstract:

L’initiative «Web des données» a mis en disponibilité des millions des données pour leur interrogation par une fédération de participants autonomes. Néanmoins, le Web des Données a des problèmes de hétérogénéité et qualité. Nous considérons le problème de hétérogèneité comme une médiation «Local-as-View» (LAV). Malheureusement, LAV peut avoir besoin d’exécuter un certain nombre de « reformulations » exponentiel dans le nombre de sous-objectifs d’une requête. Nous proposons l’algorithme «Graph-Union» (GUN) pour maximiser les résultats obtenus á partir d’un sous-ensemble de reformulations. GUN réduit le temps d’exécution et maximise les résultats en échange d’une utilisation de la mémoire plus élevée. Pour permettre aux participants d’améliorer la qualité des données, il est nécessaire de faire évoluer le Web des Données vers Lecture-Écriture, par contre, l’écriture mutuelle des données entre participants autonomes pose des problèmes de cohérence. Nous modélisons le Web des Données en Lecture -Écriture comme un réseau social où les acteurs copient les données que leur intéressent, les corrigent et publient les mises à jour pour les échanger. Nous proposons deux algorithmes pour supporter cet échange : SU-Set, qui garantit la Cohérence Inéluctable Forte (CIF), et Col-Graph, qui garantit la Cohérence des Fragments, plus forte que CIF. Nous étudions les complexités des deux algorithmes et nous estimons expérimentalement le cas moyen de Col-Graph, les résultats suggèrant qu'il est faisable pour des topologies sociales
The Linked Data initiative has made available millions of pieces of data for querying through a federation of autonomous participants. However, the Web of Linked data suffers of problems of data heterogeneity and quality. We cast the problem of integrating heterogeneous data sources as a Local-as-View mediation (LAV) problem, unfortunately, LAV may require the execution of a number of “rewritings” exponential on the number of query subgoals. We propose the Graph-Union (GUN) strategy to maximise the results obtained from a subset of rewritings. Compared to traditional rewriting execution strategies, GUN improves execution time and number of results obtained in exchange of higher memory consumption. Once data can be queried data consumers can detect quality issues, but to resolve them they need to write on the data of the sources, i. E. , to evolve Linked Data from Read/Only to Read-Write. However, writing among autonomous participants raises consistency issues. We model the Read-Write Linked Data as a social network where actors copy the data they are interested into, update it and publish updates to exchange with others. We propose two algorithms for update exchange: SU-Set, that achieves Strong Eventual Consistency (SEC) and Col-Graph, that achieves Fragment Consistency, stronger than SEC. We analyze the worst and best case complexities of both algorithms and estimate experimentally the average complexity of Col-Graph, results suggest that is feasible for social network topologies

Abstract:

This work addresses a gap in the foundations of computer science. In particular, only a limited number of models address design decisions in modern Web architectures. The development of the modern Web architecture tends to be guided by the intuition of engineers. The intuition of an engineer is probably more powerful than any model; however, models are important tools to aid principled design decisions. No model is sufficiently strong to provide absolute certainty of correctness; however, an architecture accompanied by a model is stronger than an architecture accompanied solely by intuition lead by the personal, hence subjective, subliminal ego. The Web of Data describes an architecture characterised by key W3C standards. Key standards include a semi-structured data format, entailment mechanism and query language. Recently, prominent figures have drawn attention to the necessity of update languages for the Web of Data, coining the notion of Read–Write Linked Data. A dynamicWeb of Data with updates is a more realistic reflection of the Web. An established and versatile approach to modelling dynamic languages is to define an operational semantics. This work provides such an operational semantics for a Read–Write Linked Data architecture. Furthermore, the model is sufficiently general to capture the established standards, including queries and entailments. Each feature is relative easily modelled in isolation; however a model which checks that the key standards socialise is a greater challenge to which operational semantics are suited. The model validates most features of the standards while raising some serious questions. Further to evaluating W3C standards, the operational mantics provides a foundation for static analysis. One approach is to derive an algebra for the model. The algebra is proven to be sound with respect to the operational semantics. Soundness ensures that the algebraic rules preserve operational behaviour. If the algebra establishes that two updates are equivalent, then they have the same operational capabilities. This is useful for optimisation, since the real cost of executing the updates may differ, despite their equivalent expressive powers. A notion of operational refinement is discussed, which allows a non-deterministic update to be refined to a more deterministic update. Another approach to the static analysis of Read–Write Linked Data is through a type system. The simplest type system for this application simply checks that well understood terms which appear in the semi-structured data, such as numbers and strings of characters, are used correctly. Static analysis then verifies that basic runtime errors in a well typed program do not occur. Type systems for URIs are also investigated, inspired by W3C standards. Type systems for URIs are controversial, since URIs have no internal structure thus have no obvious non-trivial types. Thus a flexible type system which accommodates several approaches to typing URIs is proposed.

Abstract:

A Read-While-Write (RWW) operation for tape and/or potentially disk applications is needed in the following three cases: 1. High reliability; 2. Data servo systems; 3. Buried servo systems. All these applications mean that the read (servo) head and write head are operative simultaneously. Consequently, RWW operation will require work to suppress the so-called crossfeed field radiation from the write head. Traditionally, write-read crossfeed has been reduced in conventional magnetic recording heads by a variety of screening methods, but the effectness of these methods is very limited. On the other hand, the early theoretical investigations of the crossfeed problem concentrating on the flux line pattern in front of a head structure based on a simplified model, may not be comprehensive. Today a growing number of magnetic recording equipment manufacturers employ thin-film technology to fabricate heads and thereby the size of the modern head is much smaller than in the past. The increasing use of thin-film metallic magnetic materials for heads, along with the appearance of other new technologies, such as the MR reproductive mode and keepered media, has stimulated the need for an increased understanding of the crossfeed problem by advanced analysis methods and a satisfactory practical solution to achieve the RWW operation. The work described in this thesis to suppress the crossfeed field involves both a novel reproductive mode of a Dual Magnetoresistive (DMR) head, which was originally designed to gain a large reproduce sensitivity at high linear recording densities exceeding 100 kFCI, playing the key role in suppressing the crossfeed (the corresponding signal-noise ratio is over 38 dB), and several other compensation schemes, giving further suppression. Advanced analytical and numerical methods of estimating crossfeed in single and multi track thin-film/MR heads under both DC and AC excitations can often help a head designer understand how the crossfeed field spreads and therefore how to suppress the crossfeed field from the standpoint of an overall head configuration. This work also assesses the scale of the crossfeed problem by making measurements on current and improved heads, thereby adapting the main contributors to crossfeed. The relevance of this work to the computer industry is clear for achieving simultaneous operation of the read head and write head, especially in a thin-film head assembly. This is because computer data rates must increase to meet the demands of storing more and more information in less time as computer graphics packages become more sophisticated.

Abstract:

In this dissertation, three dimensional dynamic micromagnetic modeling based on Landau-Lifshitz equation with Gilbert damping has been used to study the magnetic processes of the thin film write heads for high density and high data rate perpendicular magnetic recording. In extremely narrow track width regime, for example, around or below 100 nm, the head field is found to suffer from significant loss from the ideal AttM s value for perpendicular recording. In the meantime, remanent head field becomes significant, posing potential issue of head remanence erasure. Using micromagnetic modeling, various novel head designs have been investigated. For an overall head dimension around one micron, the shape and structure of the head yoke have been found to greatly affect the head magnetization reversal performance, therefore the field rise time, especially for moderate driving currents. A lamination of the head across its thickness, both in the yoke and in the pole tip, yields excellent field reversal speed, and more importantly, it suppresses the remanent field very well and thus making itself a simple and effective approach to robust near-zero remanence. A single pole head design with a stitched pole tip and a recessed side yoke can produce significantly enhanced head field compared to a traditional single pole head. Various head design parameters have been examined via micromagnetic modeling. Using the dynamic micromagnetic model, the magnetization reversal processes at data rates beyond 1 G bit/s have been studied. The excitation of spin wave during the head field reversal and the energy dissipation afterwards were found im portant in dictating the field rise time. Both the drive current rise time and the Gilbert damping constant affect the field reversal speed. The effect of the soft underlayer (SUL) in both the write and the read processes have been studied via micromagnetic modeling. Although it is relatively easy to fulfill the requirement for the magnetic imaging in writing, the SUL deteriorates the readback performance and lowers the achievable recording linear density. Various parameters have been investigated and solutions have been proposed. The effect of stress in magnetostrictive thin films has been studied both analytically and by simulation. The micromagnetic model has been extended to incorporate the stress-induced anisotropy effect. Simulation was done on both a magnetic thin film undergoing stresses to show the static domains and a conceptual write head design that utilizes the stress induced anisotropy to achieve better performance. A self-consistent model based on energy minimization has been developed to model both the magnetization and the stress-strain states of a magnetic thin film.

Pitch Technologies specializes their work on the HLA standard, a standard that specifies data exchange between simulators. The company provides a solution for recording HLA data into a database as raw byte data entries. In this thesis, different design solutions to store and organize recorded HLA data in a manner that reflects the content of the data are proposed and implemented, with the aim of making the data possible to query and analyze after recording. The design solutions impact on storage, read- and write performance as well as usability are evaluated through a suite of tests run on a PostgreSQL database and a TimescaleDB database. It is concluded that none of the design alternatives is the best solution for all aspects, but the most promising combination is proposed.

Abstract:

Data storage in current hard disk drives is limited by three factors. These are thermal stability of recorded data, the ability to store data, and the ability to read back the stored data. An attempt to alleviate one factor can affect others. This ultimately limits magnetic recording densities that can be achieved using traditional forms of data storage. In order to advance magnetic recording and postpone these inhibiting factors, new approaches are required. One approach is recording on Bit Patterned Media (BPM) where the medium is patterned into nanometer-sized magnetic islands where each stores a binary digit.This thesis presents a statistical model of write errors in BPM composed of single domain islands. The model includes thermal activation in a calculation of write errors without resorting to time consuming micromagnetic simulations of huge populations of islands. The model incorporates distributions of position, magnetic and geometric properties of islands. In order to study the impact of island geometry variations on the recording performance of BPM systems, the magnetometric demagnetising factors for a truncated elliptic cone, a generalised geometry that reasonably describe most proposed island shapes, were derived analytically.The inclusion of thermal activation was enabled by an analytic derivation of the energy barrier for a single domain island. The energy barrier is used in a calculation of transition rates that enable the calculation of error rates. The model has been used to study write-error performance of BPM systems having distributions of position, geometric and magnetic property variations. Results showed that island intrinsic anisotropy and position variations have a larger impact on write-error performance than geometric variations.The model was also used to study thermally activated Adjacent Track Erasure (ATE) for a specific write head. The write head had a rectangular main pole of 13 by 40 nm (cross-track x down-track) with pole trailing shield gap of 5 nm and pole side shield gap of 10 nm. The distance from the pole to the top surface of the medium was 5 nm, the medium was 10 nm thick and there was a 2 nm interlayer between the soft underlayer (SUL) and the medium, making a total SUL to pole spacing of 17 nm. The results showed that ATE would be a major problem and that cross-track head field gradients need to be more tightly controlled than down-track. With the write head used, recording at 1 Tb/in² would be possible on single domain islands.

Abstract:

Computing in the last decade has been characterized by the rise of data- intensive scalable computing (DISC) systems. In particular, recent years have wit- nessed a rapid growth in the popularity of fast analytics systems. These systems exemplify a trend where queries that previously involved batch-processing (e.g., run- ning a MapReduce job) on a massive amount of data, are increasingly expected to be answered in near real-time with low latency. This dissertation addresses the problem that existing designs for various components used in the software stack for DISC sys- tems do not meet the requirements demanded by fast analytics applications. In this work, we focus specifically on two components: 1. Key-value storage: Recent work has focused primarily on supporting reads with high throughput and low latency. However, fast analytics applications require that new data entering the system (e.g., new web-pages crawled, currently trend- ing topics) be quickly made available to queries and analysis codes. This means that along with supporting reads efficiently, these systems must also support writes with high throughput, which current systems fail to do. In the first part of this work, we solve this problem by proposing a new key-value storage system – called the WriteBuffer (WB) Tree – that provides up to 30× higher write per- formance and similar read performance compared to current high-performance systems. 2. GroupBy-Aggregate: Fast analytics systems require support for fast, incre- mental aggregation of data for with low-latency access to results. Existing techniques are memory-inefficient and do not support incremental aggregation efficiently when aggregate data overflows to disk. In the second part of this dis- sertation, we propose a new data structure called the Compressed Buffer Tree (CBT) to implement memory-efficient in-memory aggregation. We also show how the WB Tree can be modified to support efficient disk-based aggregation.

This thesis deals with an effective solution of the parallel I/O of the k-Wave tool, which is designed for time domain acoustic and ultrasound simulations. k-Wave is a supercomputer application, it runs on a Lustre file system and it requires to be implemented with MPI and stores the data in suitable data format (HDF5). I designed three methods of optimization which fits k-Wave's needs. It uses accumulation and redistribution techniques. In comparison with the native write, every optimization method led to better write speed, up to 13.6GB/s. It is possible to use these methods to optimize every data distributed application with the write speed issue.

Abstract:

Data Handover est une librairie de fonctions adaptée aux systèmes distribués à grande échelle. Dho offre des routines qui permettent d'acquérir des ressources en lecture ou en écriture de façon cohérente et transparente pour l'utilisateur. Nous avons modélisé le cycle de vie de Dho par un automate d'état fini puis, constaté expérimentalement, que notre approche produit un recouvrement entre le calcul de l'application et le contrôle de la donnée. Les expériences ont été menées en mode simulé en utilisant la libraire GRAS de SimGrid puis, en exploitant un environnement réel sur la plate-forme Grid'5000. Par la théorie des files d'attente, la stabilité du modèle a été démontrée dans un contexte centralisé. L'algorithme distribué d'exclusion mutuelle de Naimi et Tréhel a été enrichi pour offrir les fonctionnalités suivantes: (1) Permettre la connexion et la déconnexion des processus (ADEMLE), (2) admettre les locks partagés (AEMLEP) et enfin (3) associer les deux propriétés dans un algorithme récapitulatif (ADEMLEP). Les propriétés de sûreté et de vivacité ont été démontrées théoriquement. Le système peer-to-peer proposé combine nos algorithmes étendus et le modèle originel Dho. Les gestionnaires de verrou et de ressource opèrent et interagissent mutuellement dans une architecture à trois niveaux. Suite à l'étude expérimentale du système sous-jacent menée sur Grid'5000, et des résultats obtenus, nous avons démontré la performance et la stabilité du modèle Dho face à une multitude de paramètres
Data Handover is a library of functions adapted to large-scale distributed systems. It provides routines that allow acquiring resources in reading or writing in the ways that are coherent and transparent for users. We modelled the life cycle of Dho by a finite state automaton and through experiments; we have found that our approach produced an overlap between the calculation of the application and the control of the data. These experiments were conducted both in simulated mode and in real environment (Grid'5000). We exploited the GRAS library of the SimGrid toolkit. Several clients try to access the resource concurrently according the client-server paradigm. By the theory of queues, the stability of the model was demonstrated in a centralized environment. We improved, the distributed algorithm for mutual exclusion (of Naimi and Trehel), by introducing following features: (1) Allowing the mobility of processes (ADEMLE), (2) introducing shared locks (AEMLEP) and finally (3) merging both properties cited above into an algorithm summarising (ADEMLEP). We proved the properties, safety and liveliness, theoretically for all extended algorithms. The proposed peer-to-peer system combines our extended algorithms and original Data Handover model. Lock and resource managers operate and interact each other in an architecture based on three levels. Following the experimental study of the underlying system on Grid'5000, and the results obtained, we have proved the performance and stability of the model Dho over a multitude of parameters

Abstract:

This paper discusses the three levels of software transparency achievable with write once optical disk drives. First, the unusual nature of write once optical drives is addressed to demonstrate why software is needed that is different than software used with magnetic disk drives. This is followed by a framework for viewing different solutions to write-once software issues. Finally, this framework is used to examine the three levels of software transparency achievable with write-once drives.

Abstract:

Today's buyer of 5-1/4 inch Write-Once optical storage products is presented with greater choice and variety of product than ever before. The technology now offers capacities from 200 megabytes to 1.2 gigabytes, with various access times and data transfer rates. Additional issues such as external or internal mount, form factor conformance, capability of software/firmware supplied with the unit, and operating system support make the choice difficult at best. In all cases, low cost-per-megabyte figures, high capacity, and removable media are the attributes that make optical drives ideal for data intensive applications.

Abstract:

Bury Me My Love is a game about distance. It is a game which places front and center relationships between humans, how they interact, and what drives people to take a leap into the unknown and risk their lives in the hope of reaching safety. The eponymous phrase, ‘Bury Me My Love,’ is an Arabic expression to take care roughly meant to signify, “don’t think about dying before I do.” The game is inspired by but does not tell, the real-life story of Dana, a Syrian woman having left her country in September 2015.

Abstract:

This research provides a qualitative, in-depth exploration of the content writing industry in Bangladesh, identifying prevalent trends, challenges, and growth potential. The study utilizes data from 44 participants, which include content writers and clients with diverse levels of industry experience, collected via online surveys and detailed interviews. Key findings suggest that while the industry is marked by a high demand for unique, engaging, and SEO-optimized content, issues pertaining to AI’s role, market saturation, and remuneration concerns persist. Despite these challenges, strategies for success emerged, such as continuous learning, effective client-writer communication, and strategic use of AI and social media tools. The study highlights the industry’s considerable potential for growth and recommends enhancing skill sets, promoting clear communication, creating unique value propositions, and encouraging supportive industry-wide policies. The study also signals future research directions, including the exploration of AI’s impact, pay practices, professional development programs, and the differential roles of social media platforms.

Full text

Abstract:

Field crews recently collected more than 10 years of classification and mapping data in support of the North Coast and Cascades Inventory and Monitoring Network (NCCN) vegetation maps of Mount Rainier (MORA), Olympic (OLYM), and North Cascades (NOCA) National Parks. Synthesis and analysis of these 6000+ plots by Washington Natural Heritage Program (WNHP) and Institute for Natural Resources (INR) staff built on the foundation provided by the earlier classification work of Crawford et al. (2009). These analyses provided support for most of the provisional plant associations in Crawford et al. (2009), while also revealing previously undescribed vegetation types that were not represented in the United States National Vegetation Classification (USNVC). Both provisional and undescribed types have since been submitted to the USNVC by WNHP staff through a peer-reviewed process. NCCN plots were combined with statewide forest and wetland plot data from the US Forest Service (USFS) and other sources to create a comprehensive data set for Washington. Analyses incorporated Cluster Analysis, Nonmetric Multidimensional Scaling (NMS), Multi-Response Permutation Procedure (MRPP), and Indicator Species Analysis (ISA) to identify, vet, and describe USNVC group, alliance, and association distinctions. The resulting revised classification contains 321 plant associations in 99 alliances. A total of 54 upland associations were moved through the peer review process and are now part of the USNVC. Of those, 45 were provisional or preliminary types from Crawford et al. (2009), with 9 additional new associations that were originally identified by INR. WNHP also revised the concepts of 34 associations, wrote descriptions for 2 existing associations, eliminated/archived 2 associations, and created 4 new upland alliances. Finally, WNHP created 27 new wetland alliances and revised or clarified an additional 21 as part of this project (not all of those occur in the parks). This report and accompanying vegetation descriptions, keys and synoptic and environmental tables (all products available from the NPS Data Store project reference: https://irma.nps.gov/DataStore/Reference/Profile/2279907) present the fruit of these combined efforts: a comprehensive, up-to-date vegetation classification for the three major national parks of Washington State.

Abstract:

[Extract from Foreword] This ‘cruise report’ is the first of a short series, reflecting the aspiration of the Clyde Fishermen’s Association to establish a rigorous sampling scheme to monitor changes in the abundance and distribution of cod (and later other gadoid species) within the Clyde area. The Scottish Oceans Institute was approached to provide independent scientific support in early 2016. A series of surveys was then conducted in 2016, 2017 and 2018. In each survey the SOI provided observers, collected data and wrote up a cruise report detailing the methods used and the location, numbers, weights, sex and maturity states of fish caught. Trials were halted after 2018 firstly because of pressing issues resulting from Brexit which absorbed any potentially available human and other resources, and secondly because of the COVID pandemic. The reports remained as unapproved and incomplete drafts until 2022. Picking up these reports again in 2022, we have responded to reviewers’ comments since made by Marine Scotland Science and have finalised all four reports in the 2016-2018 current series.

Full text

Abstract:

“Are private schools better than public schools?” This ubiquitous debate in low- and middle-income countries is the wrong one to have. The foreword and three essays collected in this Forum each explore how to move past the stuck “public vs. private” binary. Jason Silberstein is a Research Fellow at RISE. His foreword is titled “A Shift in Perspective: Zooming Out from School Type and Bringing Neighborhood Education Systems into Focus.” It summarizes the current state of the “public vs. private” debate, outlines an alternative approach focused on neighborhood education systems, and then synthesizes key findings from the other essays. Jishnu Das has conducted decades of research on school systems in low-income countries, including in Zambia, India, and Pakistan. His essay is titled “The Emergence and Consequence of Schooling Markets.” It describes exactly what schooling markets look like in Pakistan, including the incredible variance in school quality in both public and private schools within the same village. Das then reviews the evidence on how to engineer local education markets to improve learning in all schools, including polices that have underdelivered (e.g., vouchers) and more promising policies (e.g., finance and information structured to take advantage of inter-school competition, and a focus on the lowest performing public schools). Das’ research on Pakistan is available through leaps.hks.harvard.edu, which also houses the data and documentation for the project. Lant Pritchett writes from a global lens grounded in his work on systems thinking in education. His essay is titled “Schooling Ain’t Just Learning: Controlling the Means of Producing Citizens.” It observes that governments supply, and families demand, education for many reasons. The academic emphasis on one of these reasons, producing student learning, has underweighted the critical importance of other features of education, in particular the socialization function of schooling, which more persuasively explain patterns of provision of both public school and different kinds of private schools. With this key fact in mind, Pritchett argues that there is a strong liberty case for allowing private schools, but that calls for governments to fund them are either uncompelling or “aggressively missing the point”. Joanna Härmä has done mixed-methods research on private schools across many cities and rural areas in sub-Saharan Africa and India, and has also founded a heavily-subsidized private school in Uttar Pradesh, India. Her essay responds to both Das and Pritchett and is titled “Why We Need to Stop Worrying About People’s Coping Mechanism for the ‘Global Learning Crisis’—Their Preference for Low-Fee Private Schools”. It outlines the different forces behind the rise of low-fee private schools and asserts that both the international development sector and governments have failed to usefully respond. Policy toward these private schools is sometimes overzealous, as seen in regulatory regimes that in practice are mostly used to extract bribes, and at other times overly solicitous, as seen in government subsidies that would usually be better spent improving the worst government schools. Perhaps, Härmä concludes, “we should leave well enough alone.”
