Assessing the Impact of DMAIC-Knowledge Management Methodology on Six Sigma Projects: An Evaluation through Participant’s Perception
2014
As an emerging concept, Knowledge Management (KM) has a great impact on organization and organizational performance. On the other hand, DMAIC is a well known methodology, used for solving organizational problems through Six Sigma projects.The main purpose of this study is to assess the impact of newly proposed DMAIC-KM integrated methodology in executing Six Sigma projects. For assessment, four Six Sigma projects have been executed using DMAIC-KM methodology within an airbag manufacturing unit. Afterward, the Opinion and Perception have been collected from the Project participant’s through conducting a quantitative survey regarding the Organizational benefits achieved after executing the DM…
A quantitative survey of the benthic meiofauna in the Gulf Of Riga (eastern Baltic Sea), with special reference to the structure of nematode assembla…
1998
Abstract The Gulf of Riga is relatively shallow and considered to be one of the most eutrophied areas in the Baltic Sea with an annual primary production estimated to 290 gCm-2 yr-1. Meiofauna sampling was carried out at 30 stations homogeneously spread over the Gulf of Riga, varying in depth and sediment structure. The average meiofauna abundance was 4800 ind/10 cm2, with a maximum of 17000 ind/10 cm2. Harpacticoid copepods were abundant all over the Gulf, averaging 425 ind/10 cm2. The highest number was found close to the mouth of the river Daugava, up to 1400 ind/10 cm2. Harpacticoids were significantly more abundant in sediments with medium organic content (loss on ignition (LOI) 5–10%)…
News Selection Within Customer Magazines
2017
Customer magazines blur the boundaries between journalistic reporting and organizational information. On the one hand, customer magazines are intended to communicate the interests, brands, products, and services of an organization. On the other hand, their topics, style, and layout resemble those of journalistic publications, from which readers expect independent and objective reporting. While customer magazines are distributed in high numbers throughout different industries and play an increasingly important role in the media landscape, they have hardly been the focus of researchers to date. It is therefore quite unclear how editorial decisions are made within these publications. This stud…
Borderline journalism: Why do journalists accept and justify questionable practices that establish scandals? A quantitative survey
2018
The shift from descriptive reporting toward an interpretive style of journalism can be regarded as one factor to explain the rising number of reported scandals in Western democracies. While most of these critical reports are based on actual misbehaviors, there are scandals triggered by violations of journalistic norms. This article examines the question of how many journalists accept such violations of norms and what arguments they use to justify them. To answer these questions, we conducted a quantitative online survey among German journalists in June and July 2015. Participants were confronted with descriptions of factual violations of the German press codex that triggered major scandals…
Probabilistic Contextuality in EPR/Bohm-type Systems with Signaling Allowed
2014
In this chapter, we review a principled way of defining and measuring contextuality in systems with deterministic inputs and random outputs, recently proposed and developed in \citep{KujalaDzhafarovLarsson2015,DKL2015FooP}.
MADoSPRO: a new approach to molecular modelling studies on a series of DNA minor groove binders
2006
The aim of this work was devoted to develop a method to predict Delta G values for a series of minor groove binders. Starting from a matrix of docking dataset for 10 minor groove binders (known and not) to 20 DNA fragments, with various sequences, it was possible to analyze the interaction modes and to calculate the Delta G value for new derivatives through MADoSPRO procedure. The method allowed, through the QSPR analysis, to characterize the type of interactions in such complexes, that was demonstrated to be related to quantum chemical and electrostatic descriptors, in agreement with the information available in literature on the structural requirements of specific minor groove ligands. Mo…
Light transport in hetero-opal photonic crystals
2005
The effect of photonic bandgap interface upon the light scattering was studied in hetero-opals consisting of two opal thin films with different lattice constant. It is shown that the weak scattering regime is preserved in thin hetero-opal films. By comparing scattering spectra of single and hetero-opal films recorded under reversing angles of light incidence and detection it was demonstrated that the interface scatters stronger the light at oblique incident angles. Squeezing of the scattering diagram of hetero-opals compared to single opal films is also assigned to the interface scattering.
The impact of study design and diagnostic approach in a large multi-centre ADHD study. Part 1: ADHD symptom patterns
2011
Contains fulltext : 96439.pdf (Publisher’s version ) (Open Access) BACKGROUND: The International Multi-centre ADHD Genetics (IMAGE) project with 11 participating centres from 7 European countries and Israel has collected a large behavioural and genetic database for present and future research. Behavioural data were collected from 1068 probands with the combined type of attention deficit/hyperactivity disorder (ADHD-CT) and 1446 'unselected' siblings. The aim was to analyse the IMAGE sample with respect to demographic features (gender, age, family status, and recruiting centres) and psychopathological characteristics (diagnostic subtype, symptom frequencies, age at symptom detection, and com…
A combined molecular dynamics and Monte Carlo study of the approach towards phase separation in colloid-polymer mixtures.
2011
A coarse-grained model for colloid-polymer mixtures is investigated where both colloids and polymer coils are represented as point-like particles interacting with spherically symmetric effective potentials. Colloid-colloid and colloid-polymer interactions are described by Weeks-Chandler-Andersen potentials, while the polymer-polymer interaction is very soft, of strength k(B)T/2 for maximum polymer-polymer overlap. This model can be efficiently simulated both by Monte Carlo and molecular dynamics methods, and its phase diagram closely resembles that of the well-known Asakura-Oosawa model. The static and dynamic properties of the model are presented for systems at critical colloid density, va…
Impact of prompt gamma emission of 44Sc on quantification in preclinical and clinical PET systems
2021
Abstract 44Sc is an increasingly investigated positron emitter for use in positron emission tomography (PET) imaging. However, 44Sc is a non-pure positron emitter, since prompt photons are co-emitted during the decay process. This study investigates coincidence energy spectra of 44Sc and its impact on PET quantification on a preclinical and clinical PET system in comparison with 18F. The raw data of the coincidence events revealed characteristic differences comparing the photon energy distribution of 44Sc and 18F. Due to prompt gamma emission of 44Sc, activity recovery is underestimated on PET systems. However, clinical PET imaging of 44Sc with acceptable quantitative accuracy appears feasi…
