The purpose of this paper is to provide acid‐dyes, known for the dyeing of porous aluminum oxide films, as inhibitors of the corrosion of aluminum in neutral chloride solutions.

Potentiodynamic polarization plots are recorded on mechanically pretreated aluminum using a three‐electrode cell containing 0.01 M NaCl solution with or without 0.025 mM of the acid‐dyes monosulfonic methyl orange (MO), disulfonic chromotrop RR (CH), disulfonic alphazurine A (AZ) and trisulfonic light green SF yellowish (LG). The X‐ray fluorescence technique is used in certain cases for the estimation of sulfur net content of the surface of the probes and thus of the concentration of the adsorbed dye.

The inhibition efficiency of acid dyes on corrosion of mechanically pretreated aluminum seems to be related more to the presence of a following quinonoid structure which probably contributes more to the formation of mono‐ or bi‐dentate compounds with the aluminum cations in the substrate than to the number of sulfonic groups in their molecule. Thus, the triphenylmethane dyes LG and, to a greater extent AZ, having this quinonoid structure means they are more efficient as corrosion inhibitors in near‐neutral chloride solution than the azo dyes MO and CH, that do not have it.

Selected acid‐dyes such as triphenylmethane sulfonic‐dyes, which have found wide application in the dyeing industry, seem to protect aluminum against the corrosive action of chlorides.

This paper is intended to be the nucleus for the electrochemical studies of the effectiveness of acid dyes as corrosion inhibitors for aluminum.

The purpose of this paper is to examine the factors that influence the intention of students to pirate academic e-books by integrating three main theories: ethics theory, deterrence theory, and the theory of planned behavior. The study also examines the moderating role of past piracy behavior on the relationship between the factors in the previously mentioned theories and students’ piracy intention.

The data were collected using a convenience sample of 662 university students. Based on their past behaviors, the students were grouped into “no piracy” and “piracy” groups.

The result shows that the piracy intention of both the no-piracy and piracy groups has a similar influence based on the moral obligation in ethics theory. The factors in the deterrence theory, which includes fear of legal consequences and perceived likelihood of punishment, have no significant impact on the attitudes of the two groups toward piracy. While the intention of the no-piracy group is not influenced by other internal factors, such as self-efficacy, or by external factors, such as subjective norms and facilitating conditions, the behavioral intention of the piracy group is significantly influenced by these three factors.

This study only focuses on piracy attitude and behavior in the context of e-books.

In Indonesia, the insignificant impact of factors from deterrence theory (the fear of legal consequences and perceived punishment) indicates weak law enforcement to combat digital piracy. Thus, it is imperative that law enforcement, especially regarding piracy, should be enhanced.

The significant role of ethics in the attitudes toward piracy indicates that morality serves as a moral compass to fight piracy behavior. The strong impact of subjective norms, especially in the piracy group, suggests that families should raise children and educate youth with beliefs that align with the concepts of morality.

The study integrates three theories that are most often used in piracy behavior studies: ethics theory, deterrence theory, and theory of planned behavior. In addition, the study provides empirical evidence on the moderating role of past experience in piracy behavior.

This paper aims to analyze the dynamic linkages of the energy market with the forex market. The energy market is measured by crude oil WTI, while the forex market is proxied by Brazilian real (RBRL), Mexican peso (RMXN), South African rand (RZAR), Turkish lira (RTRY) and British pound sterling (RGBP) exchange rate.

For the study, daily observations of these constituent asset classes extending from December 31, 2019, to August 16, 2022, are taken as the data. Furthermore, it is categorized into two different sub-samples in the form of the COVID-19 outbreak (December 31, 2019 to February 23, 2022) and the Russo−Ukraine invasion (February 24, 2022 to August 16, 2022). For empirical estimation, Diebold and Yilmaz model (2014) and Barunik and Krehlik test (2018) are used to examine the dynamic linkages.

The study concludes that the Mexican peso (RMXN) receives and transmits the highest spillover, while crude oil (RCOWTI) receives and transmits the least volatility to the network connection in full sample. In addition, the authors report that the dynamic linkage is not constant in the short, medium and long run. Furthermore, the spillover index in the Russo−Ukraine invasion is higher (29.92%) than full observation (22.03%) and COVID-19 outbreak (21.10%) in the short run.

This paper ventures to offer insight to investors, traders and policymakers based on normal trading days and crisis periods.

This paper aims to examine the frequency of co-movements and asymmetric dependencies between bitcoin (BTC), gold, Brent crude oil and the US economic policy uncertainty (EPU) index.

The authors use a wavelet approach and a quantile-on-quantile regression (QQR) method.

The results show a positive interdependence between BTC and commodity price returns at both medium and low frequencies over the sample period. In contrast, the dependence is negative between BTC and EPU index at both medium and low frequencies. Furthermore, the co-movements between markets are more pronounced during crises. The results show that strategic commodities and EPU index have the ability to predict BTC price returns at both medium- and long-terms. The QQR method reveals that higher gold returns tend to predict higher/lower BTC returns when the market is in a bullish/bearish state. Moreover, lower gold returns tend to predict lower (higher) BTC returns when the market is in a bearish (bullish) state (positive (negative) relationship). The lower Brent returns tend to predict higher/lower BTC returns when the market is in a bullish/bearish state. High Brent quantiles tend to predict the lower BTC returns in its extremely bearish states. Finally, higher and lower EPU changes tend to predict lower and higher BTC returns when the market is in a bearish/bullish state (negative relationship).

There is generally a lack of understanding of the linkages between BTC, gold, oil and uncertainty index across multiple frequencies. This is, as far as the authors know, the first attempt to apply both the wavelet approach and a QQR method to examine the multiscale linkages among markets under study. The findings should encourage the relevant policymakers to consider these co-movements which vary over time and in duration when setting up regulations that deem to enhance the market efficiency.

The word Ubuntu has become widely known around the world as an African humanitarian wisdom that promotes international solidarity and Indigenous knowledge. The appeal of Ubuntu,as an African traditional philosophy is the emphasis on concern for fellow human beings. The primary aim of this critical literature review is to demonstrate the role Ubuntu can play in enriching social work and shifting the Euro-American foundations of the profession in teaching diaspora African students and practicing social work with diaspora African communities. The humanitarian values of Ubuntu, however, need not be limited to Africans.

This chapter explores how Ubuntu can be adopted in teaching social work and also enriching social work theoretical underpinnings. Social work has roots in Western philosophical foundations and cultural experiences, with a primary focus on supporting disadvantaged people in communities where it is practiced.However, there is a recognised need to expand this Western orientation to include other views as social work expands to be a global academic and practice profession.

An approach to learning and teaching based on Ubuntu has been described as ‘Ubuntugogy’ (Bangura, 2005). Ubuntugogy represents a holistic educational paradigm where education plays a role beyond an individual’s acquisition of knowledge and skills but instead aims at total development for the individual scholar, their community and their physical and social environment. Social work education is aimed at equipping students with the skills to contribute to the welfare of other human beings in the same way Ubuntugogy recognises the importance of mastering skills to transform individual learners and their communities. Both are therefore focused on practical education to create a world that meets the needs of the individuals and their communities.

Ubuntu approaches view education as a means for struggle for survival and liberation from oppression. There are similar approaches in education literature that emphasise the cultural and historical aspects of education (Lave, 2019). Ubuntu philosophy has roots in African traditions and history that also have clear echoes in other traditional societies that emphasise interdependence and relationships between people and their physical world in an intricate web of life.

Social work can learn from Ubuntu if it is to move beyond its traditional Western roots. Ubuntu and social work share the commonality of concern for human welfare. Ubuntu goes a step further in emphasising the intricate linkages between humans and nature in a non-hierarchical web. Social work can also enrich Ubuntu with its body of knowledge, accumulated since the late 19th century, in practical application of the identified Ubuntu ideals. This chapter presents an attempt at such a dialogue.

In this chapter, the interest is directed towards how transnational policy messages (supra-level) can be tracked down through analyses of curriculum policy discourses at the national (macro-level) and municipal level (meso-level) in the Swedish school system. Drawing on discursive institutionalism, and organizational and institutional theory, we analyse central policy messages in the introduction of the national Swedish standards-based curriculum reform for compulsory school from 2011, focusing on discourses of communication between local authorities (meso-level) and schools (micro-level) within their area of responsibility for curriculum making. Two main features emerge. The local curriculum reform agenda is significantly shaped by the argument that explicit standards together with systematic governance through evaluation and accountability will increase students' performance. The second feature underlines strong accountability as a prerequisite for equity and equivalence and the importance of the local school authority for the organization of schooling, structural support and interventions for curriculum making in schools. Equity and equivalence are a challenge for the local authorities. They have problems to support curriculum making which tends to create considerable variations in how the curriculum reform is enacted in the different schools of the municipality.

LIBRARIES, in common with all other public institutions, must be faced with the uncertainty that arises from the inconclusive results of the recent General Election. We are not intimately concerned with parties and it is held that librarians should eschew them altogether as they have duties to, are the servants of, all. This consideration applies more to the public librarian than to the special one. Be that as it may, the change must postpone, we imagine, our chances of the new Public Libraries Act, because a new general election is probable in a very short time. Meanwhile, there is always uncertainty as to public expenditure and, although we do not expect anything drastic, it is hardly likely that our centenary year will see the beginnings of the library progress for which some had hoped. Most local rate‐budgets have, fortunately, been fixed by now.

OUR readers need no apology from us for the attention given to Library Training in these pages. The amount of dissatisfaction with the present state of affairs, if it may be judged from the gossip and letters that reach us, is of some proportions. It is not to be supposed that complaints are necessarily justified. They may be made in the natural chagrin of disappointment by candidates who have failed. Alternatively, there may be reasons which have a disinterested origin. The record of passes and failures shows that in December there was a dêbacle in candidates in the subject of cataloguing, which at least merits thought. In earlier issues it has been suggested by our writers that examinations twice yearly encourage experiments in sitting. There has also been the suggestion that librarians place too much stress on qualifications for their juniors and urge them to struggle with subjects for which they cannot be ready. To pass in cataloguing a student must be able to catalogue anything from a novel to an academic thesis in Anglo‐Norman French on Phlogiston, supposing that to be possible!

ONE or two recent pronouncements in public on librarianship revive matters that some are inclined to think have been discussed enough. On another page reference is made to the not altogether novel suggestion, made lately at Hastings by Mr. E. A. Baker and now more forcibly perhaps at the Annual Meeting of the Greater London Division by Mr. Hoy, that the L.A. should be composed of a series of divisions each representing a type of library and librarians ; and that the Council should be of nominees from each of them and therefore more uniformly representative of modern library activity. A somewhat stale platitude, which we remember reading in an early volume of the LIBRARY WORLD, says “Branches are always foci of disunion” and it must be agreed that the purpose of sections is to advance their specialities, and justly. It follows that many non‐public librarians feel aggrieved at the dominance of Demos in the shape of public librarians and their assistants ; they should be confined within a section. It seems reasonable. It would however mean radical constitutional changes ; the L.A. was not primarily founded for the benefit of librarians, at least not openly, although its charter provides for the care of the training and conditions of librarians. It was to unite those who desired to advance the number and efficiency of libraries. And lay members were, and we believe still are, as entitled to membership as are library workers who are qualified, or desire to qualify as, librarians. There might, of course, be a non‐librarians section. Could there be a Local Authorities Section ? That would tidy up matters.

The purpose of this paper is to contribute to a better understanding of internationalization patterns among speciality food small to medium‐sized enterprises (SMEs), investigating dimensions that may have a bearing on such patterns, using a series of case studies. In particular the investigation seeks to gain new insights about differences among companies in their internationalization patterns. These differences are examined in a framework which tries to relate three company‐level dimensions (market, technology and space) to internationalization patterns. The three dimensions are derived from the constructs developed by Storper and Salais, and Straete.

Two research questions (RQs) are formulated: Is there a relationship between the internationalization pace of speciality food SMEs and their technology, market, and space dimensions? Is there a relationship between the internationalization modes of speciality food SMEs and their technology, market, and space dimensions? A qualitative approach was adopted and cases from a broad dataset were used. The present research is an explorative research: it is intended to provide insights from which hypotheses might be developed.

This paper provides an empirical and conceptual contribution to the food internationalization debate. On the empirical side, it provides new evidence on speciality food internationalization, showing a rather diversified set of internationalization patterns, both in terms of pace and modes. On the conceptual side, it shows that the three dimensions of technology, market and space may help to enrich the comprehension of internationalization phenomena. While data collected seem not to provide insights from which hypotheses might be developed concerning RQ1, they seem on the contrary to provide useful insights concerning RQ2.

Limitations of the research generally relate to the use of a small sample. Future research should strive to obtain larger samples, develop a set of relevant finer‐grained hypotheses and test those using appropriate statistical techniques

Identifying the impact that the three dimensions might have on internationalization patterns and vice versa may help to focus on these specific elements when companies make their internationalization decisions. On the same line, public policy agencies could benefit from these first results for better clustering companies targeting their internationalization supporting initiatives.

The findings add to the limited body of knowledge on the key influences on internationalization patterns within the food sector.
