On a limiting distribution of singular values of random band matrices
2015
An equation is obtained for the Stieltjes transform of the normalized dis- tribution of singular values of non-symmetric band random matrices in the limit when the band width and rank of the matrix simultaneously tend to infinity. Conditions under which this limit agrees with the quarter-circle law are found. An interesting particular case of lower triangular random matri- ces is also considered and certain properties of the corresponding limiting singular value distribution are given.
When Customer base is not loyalty! : Differences in the Consumers' Appraisal of Performance of Mobile Telecommunications Service Providers in Port Ha…
2017
Reports from both local and international telecommunications agencies attest that Nigerian telecommunications industry is the fastest growing in Africa and one of the fastest growing in the world. Currently, the sector boasts of about 157 million active subscribers being serviced by four dominant operators. However, there have been strident calls by consumers to the regulatory agencies to apply sanctions to the operators as a result of persistent poor quality of service. As a matter of fact, all the service providers do not deliver uniform level of service. This study is therefore aimed at examining the differences in the consumers’ appraisal of the quality of service and offerings of the s…
Environmental values in industrial marketing relationships
2017
Concern for the natural environment has become an issue that virtually all companies have to address. Literature suggests that an environmentally oriented marketing strategy, such as an environmental brand image, yields competitive advantage for the supplier in the form of improved customer outcomes and financial performance. At the same time, key barriers to environmental purchasing are found to be related to higher perceived cost and lack of environmental interest among purchasing professionals. In addition, research has repeatedly revealed a gap between customers’ environmental values and attitudes and their manifestation in purchasing behavior. This dissertation contributes to the inter…
Headmaster-teacher relationship in leading school
2013
The study explored principal-teacher relationships in four Junior High schools in the Sekyere South District of Ashanti in Ghana. One of the things that government, policy-makers and educators in Ghana rarely or never discuss is the value and significance of human connections - the relationships in schools. The focus of the study was to uncover the significance of developing and sustaining a high-quality relationship between principals and teachers for effective leadership and performance. Again, the study projects a broader conception of leadership, one that shifts away from the traditional thinking approach where the figure-head is seen as ultimately responsible for the school outcomes, t…
The Correlation Between Human Capital and Gross Added Value in the Bioeconomy Sectors at the European Union (EU) Country Level
2019
Abstract The paper aims to prove the link between human capital and gross added value in bioeconomy sectors in the EU countries. Data from EUROSTAT data base regarding employment and gross added value in 6 bioeconomy sectors were used in a cross-country regression analysis. The econometric analysis of cross-country data shows a positive correlation between human capital in bioeconomy sectors and their gross output in 2015 in 26 European countries. It is found also that the correlation is stronger in the highly developed economies as in the central-eastern countries, as well as in the European economy.
Spoken-Word Segmentation and Dyslexia
2002
We used magnetoencephalography to elucidate the cortical activation associated with the segmentation of spoken words in nonreading-impaired and dyslexic adults. The subjects listened to binaurally presented sentences where the sentence-ending words were either semantically appropriate or inappropriate to the preceding sentence context. Half of the inappropriate final words shared two or three initial phonemes with the highly expected semantically appropriate words. Two temporally and functionally distinct response patterns were detected in the superior temporal lobe. The first response peaked at approximately 100 msec in the supratemporal plane and showed no sensitivity to the semantic appr…
Solvability of a first order system in three-dimensional non-smooth domains
1985
summary:A system of first order partial differential equations is studied which is defined by the divergence and rotation operators in a bounded nonsmooth domain $\Omega\subset \bold R^3$. On the boundary $\delta\Omega$, the vanishing normal component is prescribed. A variational formulation is given and its solvability is investigated.
Toolbox for Distance Estimation and Cluster Validation on Data With Missing Values
2022
Missing data are unavoidable in the real-world application of unsupervised machine learning, and their nonoptimal processing may decrease the quality of data-driven models. Imputation is a common remedy for missing values, but directly estimating expected distances have also emerged. Because treatment of missing values is rarely considered in clustering related tasks and distance metrics have a central role both in clustering and cluster validation, we developed a new toolbox that provides a wide range of algorithms for data preprocessing, distance estimation, clustering, and cluster validation in the presence of missing values. All these are core elements in any comprehensive cluster analy…
Dharmic Education - A Panacea for Social Evils in Emerging Economies
2014
Education is a tool of social change. The perceptions of people about the goals of education largely define the pattern of education structure. If the values of the society revolve around materialistic pursuits alone, it naturally promotes unbridled race for money. The products of that education system orient towards materialistic pursuits and the lofty ideals like Corporate Social Responsibility and business ethics that dominate the current managerial thought get lip sympathy in their hands. Realizing the need of ethical values in organizations, many universities of the West and certain prime institutions in India (ex- IIM, Bangalore) have introduced spiritual education in the course curri…
Jevons on the Ricardian Theory of Distribution. An Interpretation
2004
The paper reconstructs Jevons' strategy of interpretation of Ricardian economics in the light of some hermeneutic categories. Jevons' basic goal appears to be a critical assessment of the net scientific content of Classical economics. He envisages a three steps exegetical strategy: first he points out the scientific standards all economic theories should conform to and elaborates his new economic theory in compliance with these standards; then he scrutinizes the corpus of received economic doctrines in the light of his theory and, finally, he passes his sentence. Jevons' belief that truth in economics is one prevents him to recognize that what he calls scientific errors may actually be theo…
