Dominant Leadership Themes in the Pauline Epistles

Abstract Paul’s writings in the Bible, although primarily intended to serve spiritual ends, were found to also contain practical leadership wisdom long before these concepts were developed and formalized in secular leadership literature. Seven leadership themes emerged out of this conceptual study, namely: concepts of authority, responsibility, and accountability; the need for personal integrity among leaders, the need to build ethical organizations, situational leadership, fostering unity in diversity, the teaching role of leaders, and ensuring organizational continuity and organizational growth. This paper will benefit leadership theory along the line of increasing confidence in the use of the Bible as a source of leadership knowledge. It will also support leadership practice by providing a model of how effective leadership can be practiced despite operating in a turbulent ancient environment devoid of the resources, systems, and technologies of today’s post-modern organizations. Although the contexts in Paul’s epistles were churches, the leadership lessons they contained can be applied to business organizations, government entities, educational institutions, and society in general

HTself2: Combining p-values to Improve Classification of Differential Gene Expression in HTself

HTself is a web-based bioinformatics tool designed to deal with the classification of differential gene expression for low replication microarray studies. It is based on a statistical test that uses self-self experiments to derive intensity-dependent cutoffs. The method was previously described in Vêncio et al, (DNA Res. 12: 211- e 214, 2005). In this work we consider an extension of HTself by calculating p-values instead of using a fixed credibility level α. As before, the statistic used to compute single spots p-values is obtained from the gaussian Kernel Density Estimator method applied to self-self data. Different spots corresponding to the same biological gene (replicas) give rise to a set of independent p-values which can be combined by well known statistical methods. The combined p-value can be used to decide whether a gene can be considered differentially expressed or not. HTself2 is a new version of HTself that uses the idea of p-values combination. It was implemented as a user-friendly desktop application to help laboratories without a bioinformatics infrastructure

Probing doubly charged Higgs in e+e−e^+ e^- Colliders in 3-3-1 Model

The SU(3)_L\otimesU(1)_N electroweak model predicts new Higgs bosons beyond the one of the standard model. In this work we investigate the signature and production of doubly charged Higgs bosons in the $e^-e^+$ International Linear Collider and in the CERN Linear Collider. We compute the branching ratios for the doubly charged gauge bosons of the model.Comment: 17 pages, 12 figure

Data mining with neural networks and support vector machines using the R/rminer tool

We present rminer, our open source library for the R tool that facilitates the use of data mining (DM) algorithms, such as neural Networks (NNs) and support vector machines (SVMs), in classification and regression tasks. Tutorial examples with real-world problems (i.e. satellite image analysis and prediction of car prices) were used to demonstrate the rminer capabilities and NN/SVM advantages. Additional experiments were also held to test the rminer predictive capabilities, revealing competitive performances.Fundação para a Ciência e a Tecnologia (FCT) - PTDC/EIA/64541/200

Classifying the computational power of stochastic physical oracles

Consider a computability and complexity theory in which the classical set-theoretic oracle to a Turing machine is replaced by a physical process, and oracle queries return measurements of physical behaviour. The idea of such physical oracles is relevant to many disparate situations, but research has focussed on physical oracles that were classic deterministic experiments which measure physical quantities. In this paper, we broaden the scope of the theory of physical oracles by tackling non-deterministic systems. We examine examples of three types of non-determinism, namely systems that are: (1) physically nondeterministic, as in quantum phenomena; (2) physically deterministic but whose physical theory is non-deterministic, as in statistical mechanics; and (3) physically deterministic but whose computational theory is non-deterministic caused by error margins. Physical oracles that have probabilistic theories we call stochastic physical oracles. We propose a set SPO of axioms for a basic form of stochastic oracles. We prove that Turing machines equipped with a physical oracle satisfying the axioms SPO compute precisely the non-uniform complexity class BPP//log* in polynomial time. This result of BPP/log* is a computational limit to a great range of classical and non-classical measurement, and of analogue-digital computation in polynomial time under general conditions.info:eu-repo/semantics/publishedVersio

A hierarchy for BPP//log* based on counting calls to an oracle

Algorithms whose computations involve making physical measurements can be modelled by Turing machines with oracles that are physical systems and oracle queries that obtain data from observation and measurement. The computational power of many of these physical oracles has been established using non-uniform complexity classes; in particular, for large classes of deterministic physical oracles, with fixed error margins constraining the exchange of data between algorithm and oracle, the computational power has been shown to be the non-uniform class BPP//log⋆ . In this paper, we consider non-deterministic oracles that can be modelled by random walks on the line. We show how to classify computations within BPP//log⋆ by making an infinite non-collapsing hierarchy between BPP//log⋆ and BPP . The hierarchy rests on the theorem that the number of calls to the physical oracle correlates with the size of the responses to queries.info:eu-repo/semantics/publishedVersio

Signatures of Double Charged Higgs in SU(3)L⊗U(1)NSU(3)_L\otimes U(1)_N model

The scalar sector of the simplest version of the 3-3-1 electroweak models is constructed with three Higgs triplets only. We show that a relation involving two of the constants of the Higgs potential, two vacuum expectation values of the neutral scalars and the mass of the doubly charged Higgs boson leads to important information concerning the signals of this scalar particle.Comment: 6 pages and 9 figure
