Chemical Metallization

Purpose This paper aims to present the possibility of computer-aided technology of chemical metallization for the production of electrodes and resistors based on Ni-P and Ni-Cu-P layers. Design/methodology/approach Based on the calculated parameters of the process, test structures were made on an alumina substrate using the selective metallization method. Dependences of the surface resistance on the metallization time were made. These dependencies take into account the comparison of the calculations with the performed experiment. Findings The author created a convenient and easy-to-use tool for calculating basic Ni-P and Ni-Cu-P layer parameters, namely, surface resistance and temperature coefficient of resistance (TCR) of test resistor, based on chemical metallization parameters. The values are calculated for a given level of surface resistance of Ni-P and Ni-Cu-P layer and defined required range of changes of TCR of test resistor. The calculations are possible for surface resistance values in the range of 0.4 Ohm/square ÷ 2.5 Ohm/square. As a result of the experiment, surface resistances were obtained that practically coincide with the calculations made with the use of the program created by the authors. The quality of the structures made is very good. Originality/value To the best of the authors’ knowledge, the paper presents a new, unpublished method of manufacturing electrodes (resistors) on silicon, Al2O3 and low temperature co-fired ceramic substrates based on the authors developed computer program.

Quality Register

Purpose After the “quantity era,” today higher education has entered into the “quality era” and as “the gate keepers of quality,” quality assurance agencies (QAAs) are playing more and more irreplaceable important roles and their social status are becoming more and more prominent. However, how to guarantee the quality of the QAAs? Who can review the QAAs? The purpose of this paper is based exploration of these questions. Design/methodology/approach Following the founding of the European Quality Assurance Register (EQAR) for Higher Education, the Asia Pacific Quality Register (APQR) became the second in the international quality assurance (QA) networks to implement QA register, in 2015 with initiative of Asia-Pacific Quality Network. Findings This paper first retrospects the history and process of APQR, and subsequently the implementation of APQR is described in detail from the two aspects of the criteria and the procedure, and at the end, the paper concludes with a summary of the three characteristics of this first formal implement of APQR: APQR is an international register open to all the QAAs; APQR emphasizes characteristics evaluation of diversity; and APQR highlights the combination of quantitative assessment and qualitative assessment. Originality/value Today on the international stage of QA, APQR has emerged as “the watchman of quality” in the Asia-Pacific region as counterpart of EQAR in Europe. How far away does such newly emerging form of guaranteeing the QAAs’ quality go forward, what is its future prospects and other concerning issues, are some of the question that need enthusiastic attention and contribution.

Chaboche Model

Purpose The purpose of this paper is to highlight the performance of the Chaboche model in relation to the database identification, tests with imposed deformations were conducted at room temperature on 304L stainless steel specimens. Design/methodology/approach The first two tests were performed in tension-compression between ±0.005 and ±0.01; in the third test, each cycle is composed of the combination of a compression tensile cycle between ±0.01 followed by a torsion cycle between ±0.01723 (non-proportional path), and the last, uniaxial ratcheting test with a mean stress between 250 MPa and −150 MPa. Several identifications of a Chaboche-type model were then performed by considering databases composed of one or more of the cited tests. On the basis of these identifications, the simulations of a large number of ratchet tests in particular were carried out. Findings The results present the effect of the optimized parameters on the prediction of the behavior of materials which is reported in the graphs, Optimizations 1 and 2 of first and second tests and Optimization 4 of the third test giving a good prediction of the increasing/decreasing pre-deformation amplitude. Originality/value The quality of the model's predictions strongly depends on the richness of the database used for the identification of the parameters.

Purpose Seniors are nowadays at the core of important reflections to understand both how to ensure them a proper quality of life and better recognize their social role, providing them services and proper health care to value them as persons and resources. This paper aims to find a through definition about who is a senior, in the author’s opinion the starting point to help them flourishing. Design/methodology/approach As an example of definitions, an online dictionary and two geriatric text-books are quoted, highlighting qualities and rights referred to seniors especially in the delicate context of the health-care system. Findings The lack of a commonly shared perspective on this delicate kind of patient entails the difficulty to reach a coherent and satisfying definition about who a senior is. Originality/value The lack of a commonly shared definition leads to inevitable misunderstandings and could explain the arduousness of considering seniors in all their aspects. Further investigations are suggested.

Practical Implications

Purpose It has recently become more acknowledged that there is a quality of “messiness” to the qualitative research process. The purpose of this paper is to introduce the fieldpath approach—a hermeneutically inspired framework—to account for the non-linearity, uncertainty and ambiguity of the research process. Design/methodology/approach This conceptual paper reviews how the scope of hermeneutics has been partly misunderstood. The paper discusses how the scope of hermeneutics has lately been expanded by works such as Günter Figal’s (2010) Objectivity: The Hermeneutical and Philosophy. Findings The fieldpath approach proposes that a heightened relation to materiality enables the messiness of the process to be preserved, while at the same time offering a way to find one’s footing in the midst of ontologically incomplete phenomena that are still—in a processual fashion—forming and becoming. Research limitations/implications This is a conceptual paper. In addition to the research mentioned here, more studies would be needed to legitimise, test and refine the approach. Practical implications Objectivity provides an additional criterion for researchers to lean on when facing the non-linearity and unexpected turns inherent in the qualitative research process. Social implications The stress on materiality involves an ethical dimension. Post-human ethics are concerned with the future environmental consequences and sustainability of the material world. The way that matter matters in our methodologies is of primary importance. Originality/value First, the paper emphasises that hermeneutics, contrary to the common perception, does offer criteria for evaluating between interpretations. Second, it introduces the notion of hermeneutic objectivity, which stresses the importance of materiality for interpretations. Third, it introduces the fieldpath approach, which, based on the previous criterion of hermeneutic objectivity, allows for the messiness of the research process, while also preserving a tight grip on the hermeneutic imperative of “understanding in a new way”.

PurposeThe purpose of this paper is to examine and verify the competitive intelligence tools Alexa and SimilarWeb, which are broadly used for website traffic data estimation. Tested tools belong to the state of the art in this area.Design/methodology/approachThe authors use quantitative approach. Research was conducted on a sample of Czech websites for which there are accurate traffic data values, against which the other data sets (less accurate) provided by Alexa and SimilarWeb will be compared.FindingsThe results show that neither tool can accurately determine the ranking of websites on the internet. However, it is possible to approximately determine the significance of a particular website. These results are useful for another research studies which use data from Alexa or SimilarWeb. Moreover, the results show that it is still not possible to accurately estimate website traffic of any website in the world.Research limitations/implicationsThe limitation of the research lies in the fact that it was conducted solely in the Czech market.Originality/valueSignificant amount of research studies use data sets provided by Alexa and SimilarWeb. However, none of these research studies focus on the quality of the website traffic data acquired by Alexa or SimilarWeb, nor do any of them refer to other studies that would deal with this issue. Furthermore, authors describe approaches to measuring website traffic and based on the analysis, the possible usability of these methods is discussed.

Systemic Corruption

Purpose Corruption affects development and quality of life of citizens in affected countries. The increase in anti-corruption measures globally reflects a consensus that corruption is pervasive and costly. Public procurement is one area in which corruption manifests because of the sums of money involved; the asymmetry of information; and the bureaucratic nature of decision-making, which presents opportunities for abuse. In developing countries, procurement corruption is rife because of institutional weaknesses, lack of enforced accountability mechanisms and culture of silence in relation to public sector malfeasance. Design/methodology/approach This paper examines procurement corruption in countries with systemic corruption, using Nigeria as a case study, to determine how to reduce public procurement corruption. Findings The paper will highlight prevalent corrupt schemes in public procurement in Nigeria, examine the reasons for the failure of state anti-corruption institutions and analyze the kinds of initiatives that reduced procurement corruption and increased accountability in other countries and the utility of adopting such mechanisms in the Nigerian context.

Purpose This paper aims to examine the relationship between the level of sustainability and tax evasion and test whether the level of corruption moderates such a relationship. Design/methodology/approach The sample consists of 65 developed and developing countries. Tax evasion is measured using a macro indirect approach used by Schneider et al. (2010). The sustainability level and corruption variables are collected from The Global Competitiveness Report for 2012-2013. Findings This study finds that the level of tax evasion is negatively associated with the level of sustainability (overall score and social and environmental score) and the quality of infrastructure. When we distinguish between low- and high-corruption countries, we find that this negative association is significant for low-corruption countries and insignificant for high-corruption countries. These results imply that the level of corruption may reduce the tendency of individuals in a given state to accept and trust their government in general and comply with the tax rules in particular. Originality/value Our empirical findings have policy implications for governments with high levels of tax evasion, as they highlight the importance of states’ engagements towards their citizens in reducing tax evasion.
