Business intelligence – enabling self-service: A case study in a global manufacturing company

Business intelligence (BI) is an information process that includes the activities and applications used to transform business data into valuable business information. Today’s enterprises are collecting detailed data which has increased the available business data drastically. In order to meet changing customer needs and gain competitive advantage businesses try to leverage this information. However, IT departments are struggling to meet the increased amount of reporting needs. Therefore, recent shift in the BI market has been towards empowering business users with self-service BI capabilities. The purpose of this study was to understand how self-service BI could help businesses to meet increased reporting demands. The research problem was approached with an empirical single case study. Qualitative data was gathered with a semi-structured, theme-based interview. The study found out that case company’s BI system was mostly used for group performance reporting. Ad-hoc and business user-driven information needs were mostly fulfilled with self-made tools and manual work. It was felt that necessary business information was not easily available. The concept of self-service BI was perceived to be helpful to meet such reporting needs. However, it was found out that the available data is often too complex for an average user to fully understand. The respondents felt that in order to self-service BI to work, the data has to be simplified and described in a way that it can be understood by the average business user. The results of the study suggest that BI programs struggle in meeting all the information needs of today’s businesses. The concept of self-service BI tries to resolve this problem by allowing users easy self-service access to necessary business information. However, business data is often complex and hard to understand. Self-serviced BI has to overcome this challenge before it can reach its potential benefits.

Mapping and controlling molecular processes: The application of control theory and system identification algorithms to ASOPS and other fast pulse spectroscopies

Asynchronous Optical Sampling (ASOPS) [1,2] and frequency comb spectrometry [3] based on dual Ti:saphire resonators operated in a master/slave mode have the potential to improve signal to noise ratio in THz transient and IR sperctrometry. The multimode Brownian oscillator time-domain response function described by state-space models is a mathematically robust framework that can be used to describe the dispersive phenomena governed by Lorentzian, Debye and Drude responses. In addition, the optical properties of an arbitrary medium can be expressed as a linear combination of simple multimode Brownian oscillator functions. The suitability of a range of signal processing schemes adopted from the Systems Identification and Control Theory community for further processing the recorded THz transients in the time or frequency domain will be outlined [4,5]. Since a femtosecond duration pulse is capable of persistent excitation of the medium within which it propagates, such approach is perfectly justifiable. Several de-noising routines based on system identification will be shown. Furthermore, specifically developed apodization structures will be discussed. These are necessary because due to dispersion issues, the time-domain background and sample interferograms are non-symmetrical [6-8]. These procedures can lead to a more precise estimation of the complex insertion loss function. The algorithms are applicable to femtosecond spectroscopies across the EM spectrum. Finally, a methodology for femtosecond pulse shaping using genetic algorithms aiming to map and control molecular relaxation processes will be mentioned.

Supply management capabilities, routine bundles and their impact on firm performance

Despite the generally positive contribution of supply management capabilities to firm performance their respective routines require more depth of assessment. Using the resource-based view we examine four routines bundles comprising ostensive and performative aspects of supply management capability – supply management integration, coordinated sourcing, collaboration management and performance assessment. Using structural equation modelling we measure supply management capability empirically as a second-order latent variable and estimate its effect on a series of financial and operational performance measures. The routines-based approach allows us to demonstrate a different, more fine-grained approach for assessing consistent bundles of homogeneous patterns of activity across firms. The results suggest supply management capability is formed of internally consistent routine bundles, which are significantly related to financial performance, mediated by operational performance. Our results confirm an indirect effect of firm performance for ‘core’ routines forming the architecture of a supply management capability. Supply management capability primarily improves the operational performance of the business, which is subsequently translated into improved financial performance. The study is significant for practice as it offers a different view about the face-valid rationale of supply management directly influencing firm financial performance. We confound this assumption, prompting caution when placing too much importance on directly assessing supply management capability using financial performance of the business.

Analyses of the modifications in the pi circuits for inclusion of frequency influence in transmission line representation

In this article, it is represented by state variables phase a transmission line which parameters are considered frequency independently and frequency dependent. It is analyzed what is the reasonable number of pi circuits and the number of blocks composed by parallel resistor and inductor in parallel for reduction of numerical oscillations. It is simulated the numerical routine with and without the effect of frequency in the longitudinal parameters. Initially, it is used state variables and pi circuits representing the transmission line composing a linear system which is solved by numerical routines based on the trapezoidal rule. The effect of frequency on the line is synthesized by resistors and inductors in parallel and this representation is analyzed in details. It is described transmission lines and the frequency influence in these lines through the state variables.

3D raytracing through homogeneous anisotropic media with smooth interfaces

O raio conectando dois pontos em um meio anisotrópico, homogêneo por partes e com variação lateral, é calculado utilizando-se técnicas de continuação em 3D. Se combinado com algoritmos para solução do problema de valor inicial, o método pode ser estendido para o cálculo de eventos qS₁ e qS₂. O algoritmo apresenta a mesma eficiência e robustez que implementações de técnicas de continuação em meios isotrópicos. Rotinas baseadas neste algoritmo têm várias aplicações de interesse. Primeiramente, na modelagem e inversão de parâmetros elásticos na presença de anisotropia. Em segundo lugar, as iterações de Newton-Raphson produzem atributos da frente de onda como vetor vagarosidade e a matrix hessiana do tempo de trânsito, quantidades que permitem determinar o espalhamento geométrico e aproximações de segunda ordem para o tempo de trânsito. Estes atributos permitem calcular as amplitudes ao longo do raio e investigar os efeitos da anisotropia no empilhamento CRS em modelos de velocidade simples.

Beta-lactam allergy in adults with cystic fibrosis

Background: Allergic reactions to one or more beta-lactam antibiotic can pose a management problem in patients with cystic fibrosis (CF), and may limit antibiotic choice. Method: The aim of this study was to assess the prevalence of allergy to anti-pseudomonal beta-lactam antibiotics in an adult CF centre and to assess variables, which may contribute to the development of allergic reactions. A questionnaire-based interview and a review of medical records were performed. Results: Of the 150 patients, 54 (36%) had allergic reactions to one or more beta-lactam antibiotics and 20 (19%) had allergic reactions to multiple beta-lactam antibiotics. The proportion of patients allergic to specific beta-lactam antibiotics varied from 10% to 26%. Rates of reactions were highest for penicillins and cephalosporins, intermediate for carbepenems and lowest for aztreonam. Of all reactions, 40% occurred within 24 h of the commencement of an individual antibiotic course. Patients with one or more beta-lactam allergic reactions had received greater cumulative exposure (p < 0.0001), were older (p=0.016) and had lower lung function (p=0.037) than patients without a history of beta-lactam allergy. Cystic Fibrosis transmembrane regulator (CFTR) status, gender, peripheral blood eosinophil count and total IgE concentrations were not different in patients with allergic reactions. Conclusions: This study demonstrates that the prevalence of allergic reactions to beta-lactam antibiotics is high in adults with CF. Increasing age; cumulative exposure and decreasing FEV1 were associated with the development of allergy. (C) 2006 European Cystic Fibrosis Society. Published by Elsevier B.V. All rights reserved.

Beszállítófejlesztés és lean beszállítófejlesztés = Supplier development and lean supplier development

A tanulmány általános áttekintést ad a beszállítófejlesztésről. A szakmában elterjedt fogalmak, a meghatározó koncepcionális keretek, az ajánlott szervezeti megoldások és az eredményes megvalósítást támogató és gátló tényezők számba vétele arra szolgál, hogy tág kontextusban értelmezhessük a lean beszállítófejlesztést. A lean beszállítófejlesztés intézményesített szervezeti rutinok halmazát jelenti – a japán autóipari nagyvállalatok gyakorlata alapján. Egyszerre van jelen az ad hoc problémamegoldás és a folyamatorientált, tág és stratégiai beszállítófejlesztés. A kulcsbeszállítók állnak a középpontban. A beszállítókkal való együttműködésben a bilaterális kapcsolatok (beszerző-beszállító) és a multilaterális kapcsolatok (beszerző és beszállítók csoportja) is fontos szereppel bírnak. A tevékenységek megvalósításában több tucat alkalmazott főállásban vesz részt. Ezek az alkalmazottak a beszerző vállalat termelési rendszerének, működési filozófiájának is szakértői. A globális nagyvállalatoknál – adott régióban is – több osztály, esetenként egymástól függetlenül is foglalkozik a beszállítók fejlesztésével. A sikeres megvalósítást és részvételt, elköteleződést támogatja, hogy az ösztönzési rutinok is formalizáltak és intézményesítettek (pl. hatalmi kérdések, elért haszon megosztása, partnerek felelőssége). _____ Our study reviews supplier development (SD) and lean supplier development literature. The first part gives an overview about general SD and related definitions, conceptual frameworks, organisational settings and supporting/impeding factors influencing the success of SD efforts. The second part of the study positions lean supplier development in this general SD context. Lean SD is built on sets of institutionalized organisational routines – based on daily practice of Japanese automotive companies. Lean SD contains of different SD approaches. It is pervaded by both ad hoc problem solving activities and process-focused, wide and strategic approaches at the same time. The efforts are focused on key suppliers. The SD is organised through bilateral (purchaser firm and supplier firm) and multilateral (purchaser firm and supplier firms) relations. At global automotive companies more dozens full time employees work on SD. These employees are expert of the production system and operating philosophy of the purchaser company. Global firms – even in a particular geographical area – have usually more departments responsible for SD. Eventually these departments work independently from each other. To achieve the expected performance improvement and real involvement and commitment it is critical to formalize and institutionalize routines influencing motivation as well (eg., power, gain sharing, responsibilities).

Skolad blick på blommor : Formandet av yrkeskunnande i floristutbildning

This article-based thesis focuses on the formation of vocational knowing within adult and upper secondary floristry education in Sweden. Three articles explore classroom interaction and assessment actions; a fourth considers changes in vocational subject matter during the period 1990–2015. While the first three articles draw on empirical data in the form of video and audio recordings in combination with participant observation, the fourth is based primarily on material-based interview data. All four articles share a sociocultural perspective on educational practice (Wertsch, 1998; Säljö, 2011, 2013) and a relational view of knowing (e.g., Carlgren, 2015; Molander, 1996), in combination with the use of conversation analysis (Goodwin & Heritage, 1990; Sahlström & Melander, 2010) as a tool to illuminate the formation of vocational knowing. The interaction between teacher, student, and floral arrangement is foregrounded to facilitate analysis of the formation of vocational knowing. The results contribute to our understanding of the schooling of the gaze (Goodwin, 1994; Grasseni, 2009, 2011) as appropriated by participants in the interaction. Floristry vocational knowing is shown to evolve in the temporal dimension, encompassing (a) financial and aesthetic values, (b) verbal and non–verbal communication, (c) botanical material and tools, and (d) making. The respective roles and interrelations of these four components of vocational knowing in floristry are discussed. The contribution of the thesis is twofold. First, these articles contribute to the understanding of vocational education through close appraisal of the formation of vocational knowing. Second, in exploring the previously under-researched field of Swedish floristry vocational education, the thesis bridges a gap in existing knowledge of the evolution of Swedish vocational education. As floristry education is little researched internationally, the thesis also contributes to the wider body of international research. 

Intervenção precoce em contextos naturais : uma revisão sistemática da literatura

A Intervenção Precoce é uma área científica que evidencia uma evolução muito significativa em poucos anos. A mudança de paradigma – do modelo centrado na criança para o modelo centrado na família – implica novos contextos e formas de prestação de serviços, sendo prática recomendada na atualidade – a intervenção em contextos naturais. Este trabalho surge assim com o objetivo de realizar uma revisão da literatura sobre esta temática: Intervenção Precoce em contextos naturais. Pretendeu-se discutir o conceito e a sua importância no panorama atual, diversos instrumentos, modelos e propostas de intervenção, bem como resultados de investigações conduzidas a nível internacional e nacional. No seio dos contextos naturais surge um conceito ainda mais específico designado como rotinas, merecendo papel de destaque pela sua relevância, num trabalho de base ecológica. Aprofundamos mais especificamente, o tema das rotinas em contexto familiar e das rotinas em contexto educativo pois o contexto educativo e domiciliário são dos contextos naturais mais referidos na literatura em crianças entre os 0 e os 6 anos de idade. A literatura científica demonstrou, de forma clara, que as rotinas que acontecem nos contextos naturais da criança são mais eficazes para apoiar e sustentar o trabalho em intervenção precoce. Concluímos ainda que é uma área que carece de investigação, tanto em termos internacionais como nacionais, estando, o nosso país mais focado no desenvolvimento e investigação de intervenções baseadas nas rotinas em contexto domiciliário do que em contexto educativo.

Corpora in the Social Sciences- How corpus-based appraches can support qualitative interview analyses

[EN]Qualitative and quantitative research approaches are often considered as incompatible, and when they are brought together in a study, the analyses often stay within the realm of the same research field. The study at hand aims at combining the two methods from the perspectives of different disciplines and tries to determine to which degree a corpus-based analysis might support the traditional content-focused approach to qualitative data and render additional results.
