Use of computers and applications by senior executives

Purpose: Analyze the relationship between the senior executive and ICT use. Design/methodology/approach: Empirical research through which we propose a framework to establish the main factors that might lead to an increase in ICT use by senior executives. Findings: The main contribution of the present study is the creation of the list of factors that affect the use of computers and applications by senior executives and a smaller group of categories. Research limitations/implications: A limitation of this research is that it should be confirmed by means of quantitative research that would allow us to test the validity of the proposed framework, and also to ascertain the relative importance of each factor. Practical implications: Thus reducing the number of factors and forming a smaller group of categories that can facilitate research. Originality/value: The list of factors that affect the use of computers and applications by senior executives and the smaller group of categories.Peer Reviewe

What groups of factors do senior executives believe affect their use of executive information systems?

In a highly competitive and turbulent environment, executives need more efficient ways to analyze their companies, markets and competitors. The aim is to help their organizations become more competitive and, as a result, survive the changes taking place around them. Executive Information Systems (EIS) can help executives access the internal and external data they need to be able to make the right decisions and achieve their organizations' objectives. We need to know the factors what senior executives believe affect their use of executive information systems because EIS, like any other software, are designed to be used directly by users, in this case, senior executives. The objective of this thesis is to uncover which factors senior executives feel affect their use of EIS, compare the factors they propose to those mentioned in other studies to determine their importance, and group the factors which affect or may affect senior executives. The methodology proposed to group these factors together is Concept Mapping. The structure of this thesis is divided into five main sections after the introduction and the discussion on motivations: the conceptual framework, research methodology, analysis and findings, reflection and discussion, references, and annexes. In the conceptual framework section I define senior executives, EIS and Technology Acceptance Model. The first research question was: Is additional qualitative research needed to find more valuable information about the factors? I can confirm that more qualitative research is necessary to uncover more valuable information about the factors (as presented in section 5.i. above). I extracted 15 factors from the initial interviews and 79 factors from the literature review. However, senior executives rated the 15 initial factors taken from interviews higher than the rest of factors. The second research question was: What groups of factors do senior executives believe affect their use of executive information systems? Examining the results of the survey with MDS and cluster analysis, I have presented twelve groups of factors in section 5.ii. The third research question was: How important are these groups of factors for senior executives? I detail the list of clusters ordered by their average ranking in terms of importance and the average score received. The main scientific contribution of this thesis is having completed one small part of research on one of the most tested and studied theories in IT: TAM. This thesis demonstrates the importance that qualitative research has in terms of studying one type of IT and one type of user before carrying out quantitative research. The main methodological contribution is that it is not easy to do research with senior executives, but, as this thesis shows, the Concept Mapping methodology can help facilitate this process. There are other scientific and methodological contributions detailed in the thesis. This is, I believe, my modest contribution to offering senior executives EIS projects which understand them and their needs more and better while also providing researchers new opportunities for research and I would encourage other researchers to study the importance of previous qualitative studies applied to other kinds of users and systems. Another opportunity for research is to use concept maps to develop implementation projects and compare the success of those projects with other projects which didn't use the concept map as a tool to define the project itsel

La incidencia del salario mínimo interprofesional en sectores de bajos salarios

The minimum wage is an issue that is in discussion again. Most of the analyses are focus on its possible negative impact on employment. However, very few studies addressing whether the minimum wage effectively fulfills its basic purpose: to improve the incomes of low-wage earners. In this paper we address precisely this issue. In order to do it, we analyzes the evolution of wages in collective bargaining in three sectors considered low wage (retail, hospitality and cleaning), focusing on the jobs on the bottom.El salario mínimo es un tema que ha vuelto a cobrar actualidad. La mayoría de los análisis que se realizan al respecto se centran en determinar si su nivel tiene algún tipo de incidencia sobre el empleo. No obstante, son escasos los trabajos que abordan si efectivamente el salario mínimo cumple con su objetivo básico: mejorar las rentas de los perceptores de bajos salarios. En este trabajo abordamos precisamente esta cuestión. Para ello se analiza la evolución de los salarios en la negociación colectiva en tres sectores considerados de bajos salarios (comercio al por menor, hostelería y limpieza de locales y edificios), centrándonos en los puestos inferiores de la escala salarial

Coherent ONU based on 850 µm-long cavity-RSOA for next-generation ultra-dense access network

In this Letter, an efficient bidirectional differential phase-shift keying (DPSK)-DPSK transmission for a ultradense wavelength division-multiplexed passive optical network is proposed. A single distributed feedback laser at the optical network unit (ONU) is used both as the local laser for downlink coherent detection and the optical carrier for uplink. Phase-shift keying is generated using a low-cost reflective semiconductor optical amplifier (RSOA) at the ONU. The RSOA chip has the bandwidth of 4.7 GHz at the maximum input power and bias current. For uplink transmission, the sensitivity of the RSOA chip reaches -48.2 dBm at the level of bit error rate = 10(-3) for back-to-back, and the penalty for 50 km transmission is less than 1 dB when using polarization diversity.Peer ReviewedPostprint (published version

In Vitro Antifungal Susceptibility of Clinically Relevant Species Belonging to Aspergillus Section Flavi

The in vitro antifungal susceptibility of 77 isolates belonging to different clinically relevant species of Aspergillus section Flavi, including those of different phylogenetic clades of A. flavus, was tested for nine antifungal agents using a microdilution reference method (CLSI, M38-A2). Terbinafine and the echinocandins demonstrated lower MICs/MECs for all species evaluated, followed by posaconazole. Amphotericin B showed MICs >= 2 mu g/ml for 38 (49.4%) of the 77 isolates tested.Spanish Ministerio de Educacion y CienciaCoordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Universidade Federal de São Paulo, Dept Med, Special Mycol Lab LEMI, São Paulo, BrazilUniv Rovira & Virgili, Sch Med, IISPV, Mycol Unit, E-43201 Reus, SpainUniversidade Federal de São Paulo, Dept Med, Special Mycol Lab LEMI, São Paulo, BrazilSpanish Ministerio de Educacion y Ciencia: CGL 2009-08698/BOSCAPES: SWE 4150-08-2CAPES: 2312/2011CNPq: GM/GD 142051/2007-1FAPESP: 2012/01134-8Web of Scienc
