Impact of business-students subconscious in ethical decision-making
A usual management task in organizations is decision-making, and some of the most important decisions made by business leaders involve ethical components. Our behavioral-ethics-field research explores the business students (BS) subconscious influence in the ethical decision-making processes applying cases reporting ethical dilemmas. A questionnaire with neutral or non-neutral images acting as subliminal stimuli was administered to 30+30 BS trying to find out about the ethical maturity level in decision-making processes and the subconscious influences in these decisions. Cognitive biases and BS metacognitive strategies were identified when non-neutral images were present. The effects of subconscious in BS ethical decision-making are discussed.info:eu-repo/semantics/acceptedVersio
Fragmentation Phase Transition in Atomic Clusters II - Coulomb Explosion of Metal Clusters -
We discuss the role and the treatment of polarization effects in many-body
systems of charged conducting clusters and apply this to the statistical
fragmentation of Na-clusters. We see a first order microcanonical phase
transition in the fragmentation of for Z=0 to 8. We can
distinguish two fragmentation phases, namely evaporation of large particles
from a large residue and a complete decay into small fragments only. Charging
the cluster shifts the transition to lower excitation energies and forces the
transition to disappear for charges higher than Z=8. At very high charges the
fragmentation phase transition no longer occurs because the cluster
Coulomb-explodes into small fragments even at excitation energy .Comment: 19 text pages +18 *.eps figures, my e-mail adress: [email protected]

PRIvacy management responsibility on a scrutinized environment (primrose): A management method to address privacy challenges
This paper's theoretical contribution is in reporting an innovative privacy management method designated as PRIMROSE - PRIvacy Management Responsibility On a Scrutinized Environment. Research contribution is in introducing a supported process concerning the effective efficient management of privacy requirements occurring in organizations. PRIMROSE was the outcome of deductive reasoning subjected to a focus group and eight DPO interviewees scrutiny. Practical contribution is in setting the missing link regarding a generally recognized privacy management method to guide practitioners in which the elements originate from the qualitative research supporting root definitions semantics, considering, among others, principles, stages, processes, enablers and composite requirements.info:eu-repo/semantics/publishedVersio
Quark-Gluon-Plasma Formation at SPS Energies?
By colliding ultrarelativistic ions, one achieves presently energy densities
close to the critical value, concerning the formation of a quark-gluon-plasma.
This indicates the importance of fluctuations and the necessity to go beyond
the investigation of average events. Therefore, we introduce a percolation
approach to model the final stage ( fm/c) of ion-ion collisions, the
initial stage being treated by well-established methods, based on strings and
Pomerons. The percolation approach amounts to finding high density domains, and
treating them as quark-matter droplets. In this way, we have a {\bf realistic,
microscopic, and Monte--Carlo based model which allows for the formation of
quark matter.} We find that even at SPS energies large quark-matter droplets
are formed -- at a low rate though. In other words: large quark-matter droplets
are formed due to geometrical fluctuation, but not in the average event.Comment: 7 Pages, HD-TVP-94-6 (1 uuencoded figure
Student evaluation of teaching effectiveness: implications for scholars in operations management
Many times, teaching rating by students are the most influential measure of the quality of teaching departments, courses and teachers to assess how curricula changes are perceived by students. This study seeks biases introduced by background variables. If these are relevant, then student evaluations as a valid indicator of teaching effectiveness for the purpose of quality improvement and assurance could be questioned. The research purpose is (i) to appreciate the suitability of business student ratings in assessing teaching performance, and (ii) to explore limitations of current practices considering student evaluation as a primary university tool to assess teaching effectiveness.info:eu-repo/semantics/acceptedVersio
Developing a research agenda for digital accessibility in multinational enterprises
Digital accessibility for disabled people is a hot topic of Corporate Social Responsibility, mandatory under current UN and UE dispositions. This research aims at investigating its company-wide administrative integration by developing a systematic process of enquiry producing a diagnosis tool under the guidance of the Soft Systems Methodology (RQ3). Absorptive capacity provided the theoretical umbrella for structuring the problem-situation (RQ1) by setting its Root Definitions. Thus, the expected scientifically supported diagnosing tool should generate feasible and desirable changes to the problem-situation perceptions (RQ2). Digital Accessibility by Design in Service was coined to define this innovative and relevant approach.info:eu-repo/semantics/acceptedVersio
Digital accessibility in multinational enterprises: A meta study
Ever since the ratification of Directive 2016/2102 (Web Accessibility Directive) and EU Directive 2019/882 (European Accessibility Act), digital accessibility has been gaining in importance for public administration and business within the European Union. Furthermore, the role of companies has changed during the last decades and the concept of corporate social responsibility has become increasingly relevant for multinational enterprises. As one aspect of Corporate Social Responsibility, digital accessibility can bring a lot of advantages, for example by driving innovation or by enhancing a company's brand. Therefore, even companies that do not have to meet legal requirements should act with digital accessibility in mind as one part of their Corporate Social Responsibility Strategy. In the current literature and legal regulations, digital accessibility is mostly described as a technical issue, while organizational, structural aspects, and managerial tasks within the implementation of digital accessibility are ignored. By reviewing current literature, this meta-study shows the relevance of digital accessibility for multinational companies, explains why the implementation of digital accessibility cannot only be considered from a technical point of view and discusses initial approaches to examine the integration of digital accessibility into company-wide processes.info:eu-repo/semantics/publishedVersio
Definition of key drivers for project success regarding the General Data Protection Regulation
In the context of the General Data Protection Regulation (GDPR), organisational governance must consider data privacy concerns and regulations. This will avoid illegal situations, the related fines, damage to organisational reputation or, even, temporary/definitive limitation on processing activities. An innovative conceptual model is proposed to deliver the necessary change that addresses GDPR concerns based on the enablers concept. Moreover, project success is (re)examined to include stakeholders perceptions, in addition to organisational effectiveness, which is defined by the respect for legal requirements and by demonstration of compliance with the Regulation at an acceptable cost, i.e. the typical internal deliverables.info:eu-repo/semantics/acceptedVersio
Kernel Bounds for Structural Parameterizations of Pathwidth
Assuming the AND-distillation conjecture, the Pathwidth problem of
determining whether a given graph G has pathwidth at most k admits no
polynomial kernelization with respect to k. The present work studies the
existence of polynomial kernels for Pathwidth with respect to other,
structural, parameters. Our main result is that, unless NP is in coNP/poly,
Pathwidth admits no polynomial kernelization even when parameterized by the
vertex deletion distance to a clique, by giving a cross-composition from
Cutwidth. The cross-composition works also for Treewidth, improving over
previous lower bounds by the present authors. For Pathwidth, our result rules
out polynomial kernels with respect to the distance to various classes of
polynomial-time solvable inputs, like interval or cluster graphs. This leads to
the question whether there are nontrivial structural parameters for which
Pathwidth does admit a polynomial kernelization. To answer this, we give a
collection of graph reduction rules that are safe for Pathwidth. We analyze the
success of these results and obtain polynomial kernelizations with respect to
the following parameters: the size of a vertex cover of the graph, the vertex
deletion distance to a graph where each connected component is a star, and the
vertex deletion distance to a graph where each connected component has at most
c vertices.Comment: This paper contains the proofs omitted from the extended abstract
