In complex environments, a spherical robot has great application value. When the pendulum spherical robot is stopped or disturbed, there will be a periodic oscillation. This situation will seriously affect the stability of the spherical robot. Therefore, this paper aims to propose a control method based on backstepping and disturbance observers for oscillation suppression.

This paper analyzes the mechanism of oscillation. The oscillation model of the spherical robot is constructed and the relationship between the oscillation and the internal structure of the sphere is analyzed. Based on the oscillation model, the authors design the oscillation suppression control of the spherical robot using the backstepping method. At the same time, a disturbance observer is added to suppress the disturbance.

It is found that the control system based on backstepping and disturbance observer is simple and efficient for nonlinear models. Compared with the PID controller commonly used in engineering, this control method has a better control effect.

The proposed method can provide a reliable and effective stability scheme for spherical robots. The problem of instability in real motion is solved.

In this paper, the oscillation model of a spherical robot is innovatively constructed. Second, a new backstepping control method combined with a disturbance observer for the spherical robot is proposed to suppress the oscillation.

The performance of public sector institutions has always been contentious – this is as old as the system of government itself and its provision of collective goods, irrespective of whether they are tangible or intangible. In the context of South Africa, with its ever-increasing political competitiveness, this chapter assesses political leadership and the African philosophy of Ubuntu or humanism in improving public sector performance management in the country. It does so by addressing certain distinct questions: What is the state of public sector performance and leadership in South Africa? What have scholars contributed in linking public sector performance, and the politics and public administration dichotomy? Are the Batho Pele principles, underpinned by Ubuntu, a worthy notion on which to pillar African political leadership? By adopting an interpretivist, qualitative research design, the study reflects on the essence of a public administration that is effective in delivering political goods and managing the performance of bureaucracies and the political leadership therein. This chapter argues that the performance of public administrations remains a “wicked” problem in South Africa as political populism is on the rise in the country. However, the argument is made that with “good” political leadership – which naturally and effectively encompasses the philosophy of Ubuntu and which understands and mobilizes statecraft – great strides can be made beyond the current rhetoric.

This study aims to discern medieval information literacy (IL) practices through scrutiny of medieval manuscripts: both the content and the “marks of usage” evident therein.

Analysis of the writing of scribes. Engagement with selected primary texts (manuscripts) and prior scholarly investigations.

Ample evidence exists of the practice of IL in the medieval era, and how it was transmitted and negotiated across time and space. Popular guides for scholars, including Hugh of St. Victor's Didascalicon, and the marks of usage left on manuscripts by readers/scribes, are evidence of how members of scholarly communities engaged in collaborative metacognitive work, helping each other with tasks such as understanding the ordinatio (organisation) of texts; cross-referencing; locating information; and making judgments about relevance, amongst others. New practices were stimulated by key historical transitions, particularly the shift from ecclesiastical to secular settings for learning.

This is a preliminary study only, intended to lay foundations and suggest directions for more detailed future investigations of primary texts. The scope is Eurocentric, and similar work might be undertaken with the records of practice available elsewhere, e.g. the Arab world, South and East Asia.

Some previous work (e.g. Long, 2017) has investigated medieval scholarly communities by retrospectively applying notions from practice theory, but no prior work has specifically focused upon IL as the practice under investigation.

This study aims to synthesize a series of new anticorrosive pigments using a new technique called “core-shell”. This technique is based on depositing thin surface layer of expensive, efficient anticorrosive pigment on a cheap extender. This extender forms the bulk of the new pigments. The new pigments were constructed on cores of either waste silica fume or kaolin comprising 80-85 per cent of their chemical structure, and the ferrite shell was about of 20-15 per cent. Electrochemical studies were undertaken on two series of pigments for comparison between ferrites/silica fume and ferrites/kaolin pigment to show their performance, as the shells are different.

The different ferrites/silica fume and ferrites/kaolin pigments were characterized using different analytical and spectrophotometric techniques, such as X-ray fluorescence (XRF) and transmission electron microscopy (TEM). Immersion test and electrochemical impedance measurements were done in 3.5 per cent NaCl.

The tests revealed that paint films containing Sr ferrite/silica and Ca ferrite/kaolin were the most effective in corrosion prevention.

Silica fumes have a large array of uses. These pigments can be applied in various industries such as painting, wooding coating, anti-corruption coating, powder coating, architectural paint and waterproof paints. Treated kaolin can be applied in many industries besides pigment manufacture and paint formulations; it can be applied as a reinforcing filler in rubber, plastics and ceramic composites.

The new pigments are considered ecofriendly materials, because using them converts a waste product and a natural ore to useful marketable product, leading to reducing cost and saving the environment at the same time.

Technology, recognized as a key element of corporate success for high‐growth sectors, can also help companies in mature industries. Advanced technology can be used to help companies with aging product lines shift or reposition themselves into industrial sectors with faster growth and greater profits.

The purpose of this paper is to study properties of intumescent coatings based on a silicone‐epoxy hybrid resin (with an aminosilane as hardener). In the first part of this study, fire‐resistance behaviour of the intumescent coating based on silicone‐epoxy resin containing intumescent additives is evaluated. The second part assesses the effect of mineral fibres on fire‐resistant properties of intumescent coatings based on the silicone‐epoxy resin.

Thermal degradation and char formation of coatings were investigated by Thermogravimetric analyses, X‐ray diffraction and X‐ray fluorescence and infrared spectroscopy (FTIR). The salt spray corrosion test was applied to study the resistance of intumescent coatings. Anticorrosion and fire‐resistant properties after one, three and seven days of exposure were evaluated.

It was shown that a silicone‐epoxy hybrid resin is suitable for applications in the field of intumescent coatings. Intumescent coatings based on this resin form a thermally stable thin ceramic‐like layer, which improves the thermal insulation properties of the char. Mineral fibres reinforced the char structure and thus improved fire‐resistant properties of intumescent coating before as well as after the salt spray test. Mineral fibres also improved anticorrosion properties.

This paper discusses only the effect of mineral fibres on properties of intumescent coatings.

A silicone‐epoxy hybrid resin has not previously been used in intumescent coatings. This type of intumescent coating can be used as an effective passive fire protection system for steel constructions.

An attempt will be made to shed light on the course and pattern of the decentralization process by analyzing the historical development of local government and the territorial-administrative reform of 2015-2020 in Albania and the factors that have been shaping it. The scope is to understand the impact of the reform elements on the subnational governments and in general their overall impact on the government. The purpose of this paper is to fill the gap in the existing literature for Albania and at offering some insights on the administrative-territorial reform. Furthermore, it will contribute to the current debate on fiscal decentralization in South Eastern European (SEE) countries and the public management model implemented after the last reforms.

The first section analyzes the historical development of local government reforms from the 1990s to today and will help to identify if there is instrumentalism advocacy. The second section explains the determinants of the local government’s fiscal autonomy in Albania of the period from 2003 to 2016. Three indicators are used as proxies for fiscal decentralization: the proportion of subnational expenditure over national expenditure, of total subnational revenues over total revenues of central government and the indicator of own subnational revenues over total revenues of the central government. The data from the budget and the revised budgets are then compared.

Despite Albania’s commitment to decentralize its government functions, there is still work to do. The territorial and administrative reform has not generated the expected results. Almost 90 percent of the revenues still come from the central government’s unconditional transfers. Therefore, the Albanian Government should build capacities and skills, and train the employees of each level of government that currently benefit from international assistance.

The analysis represents a single case study on the territorial-administrative reform in Albania. Its implementation started in 2015 and it is probably too early to discuss outcomes. However, it might be useful to analyze the first results after a two-and-a-half-year period of implementation of reforms. Despite contributing to the existing gap in the literature, additional research will be necessary to better understand the decentralization process not only in Albania, but in all SEE countries.

It is necessary to first understand the lack of initial output, as well as the various challenges faced, in order to take the corrective measures on time.

This paper discusses in detail the reform adopted and the progress made by the Albanian local government units. The reform attempts to develop better relationships between the central and local governments and hence improve their service delivery, transparency and accountability. This paper is the first one that is attempting to analyze the initial output of the territorial-administrative reform of 2015-2020.

From the 1980s – in some parts of Europe from the 1990s – onward, the new public management (NPM) has been emerging in public organizations including libraries. Since then, there has been a need to develop strategies, to plan budgets and to implement cost and activity accounting as well as benchmarking to compare the library’s processes, costs and activities with those of other libraries. One basic idea of the NPM was to make a transition from focusing on how institutions function to product orientation, to improve the quality of library services, to develop output orientation and to act market and consumer oriented. There also was a need to change from bureaucratic and hierarchically acting organizations to a more modern flexible and lean form of management. The paper aims to discuss these issues.

The aim of this paper is in the first part to describe the basic ideas of NPM, their realization in libraries and how libraries have to handle constantly reduced budgets and the risk of being closed down (especially in the “age of austerity”); the second part will show how the University of Eastern Finland (UEF) Library has managed to improve its services with the NPM approach.

Many libraries are faced with serious financial cutbacks on the one hand and with emergent needs to (re)invest in neglected public infrastructure on the other hand. At the same time, they have to develop modern digital library services. Thus there is a need for efficiency, which is put in action via major budget cutbacks. Also many libraries have been closed down since the implementation of NPM ideas.

In this paper, the NPM tools used in the restructuring of the UEF are described and the outcome of this modern management is shown.

Micro-credentials, which have been widely used in re-skilling and skills development, provide advantages for improvement in the professional career. As a complementary approach to career and professional development in formal education, it can be said that micro-credentials are preferred for supporting professional development and/or to acquiring new skills to find a job in a new field (Fisher and Leder, 2022). This study aims to provide a detailed perspective on conceptual framework and the use of micro-credentials in higher education.

Many questions have arisen regarding micro-credentials, applicability, quality assurance, inclusion in formal educational settings and how to include them in traditional education systems, especially in higher education institutions. Oliver (2019) emphasizes that there is little research on micro-credentials or their derivatives in the literature. There is still uncertainty on micro-credential on behalf of students, employers or employees. In addition, although there are studies on micro-credentials in the USA, Europe and Australia, there is very little research around countries such as Turkey (Yilik, 2021). This study discusses the use of micro-credentials in the world and their reflections on higher education.

As it is shown in this article, micro-credentials have the potential to challenge or complement traditional ways of how learning is taking place, understood, recognized and certified. Research on micro-credentials is still in its infancy and could benefit a lot from more research. Especially research on employers' recognition and appreciation of digital credentials needs to be studied. Also, empirically confirming propositions of literature on micro-credentials could be beneficial.

This study is original in terms of discussing the use of micro-credential in the world and their reflections on higher education and presenting suggestions on this subject.

This article aims to constructively critique the new global methodology for evaluating the effectiveness of anti-money laundering regimes against defined outcomes.

With surprisingly little discussion at the intersection of the money laundering and policy effectiveness and outcomes scholarship and practice, this article combines elements of these disciplines and recent peer-review evaluations, to qualitatively assess the Financial Action Task Force’s (FATF’s) anti-money laundering “effectiveness” methodology.

FATF’s “effectiveness” methodology does not yet reflect an outcome-oriented framework as it purports. Misapplication of outcome labels to outputs and activities miss an opportunity to evaluate outcomes, as the impact and effect of anti-money laundering policies.

If the “outcomes” of the “effectiveness” framework do not match the crime and terrorism prevention policy goals of nation states, the new “main” component for assessing the effectiveness of anti-money laundering regimes potentially detracts focus and resources from, rather than towards, intended policy objectives.

There is a dearth of scholarship whether the global anti-money laundering “effectiveness” framework is sufficiently robust to assess effectiveness as it purports. This article begins addressing that gap.
