Knowing work - Cultivating a practice-based epistemology of knowledge in organization studies

While knowledge theorists urge attention to knowing in practice, two common habits in the empirical literature, which we call knowledge inherency and skepticism, function to re-center certain practitioners. The sites in which we study knowing thereby remain limited, hindering a fuller practice turn. We argue that this enduring tendency is problematic because it inhibits our understanding of ‘commu

Genetic and Family and Community Environmental Effects on Drug Abuse in Adolescence: A Swedish National Twin and Sibling Study

Objective: Using Swedish nationwide registry data, the authors investigated genetic and environmental risk factors in the etiology of drug abuse by twin sibling modeling. The authors followed up with epidemiological analyses to identify shared environmental influences on drug abuse. Method: Drug abuse was defined using public medical, legal, or pharmacy records. Twin and sibling pairs were obtaine

Doping GaP Core-Shell Nanowire pn-Junctions: A Study by Off-Axis Electron Holography

The doping process in GaP core-shell nanowire pn-junctions using different precursors is evaluated by mapping the nanowires' electrostatic potential distribution by means of off-axis electron holography. Three precursors, triethyltin (TESn), ditertiarybutylselenide, and silane are investigated for n-type doping of nanowire shells; among them, TESn is shown to be the most efficient precursor. Off-a

The effects of acquisition on the growth of new technology-based firms: Do different types of acquirers matter?

The growth of new technology-based firms (NTBFs) is usually restricted by their limited ownership and management structures. This paper explores whether acquisition, particularly that by multinational enterprises (MNEs), promotes the growth of NTBFs. Based on Swedish micro-level longitudinal data, this study further distinguishes between Swedish MNEs and foreign MNEs as acquirers and disentangles

Points to consider for prioritizing clinical genetic testing services: a European consensus process oriented at accountability for reasonableness.

Given the cost constraints of the European health-care systems, criteria are needed to decide which genetic services to fund from the public budgets, if not all can be covered. To ensure that high-priority services are available equitably within and across the European countries, a shared set of prioritization criteria would be desirable. A decision process following the accountability for reasona

Dykes of the 1.11 Ga Umkondo LIP, Southern Africa: Clues to a complex plumbing system

The Umkondo Large Igneous Province (LIP) is represented by widespread (similar to 2.0 x 10(6) km(2)) mafic intrusions that were rapidly emplaced (1112-1108 Ma) into the Kalahari craton of southern Africa and the formerly adjacent Grunehogna Province of Antarctica during Rodinia assembly. Very few Umkondo-aged dykes have been identified before, resulting in a poor understanding of this LIP's plumbi

How Green Marketing Works: Practices, Materialities and Images

There are surprisingly few empirical studies of green marketing practices, and when such studies are carried out, they tend to take a simplistic approach. In this paper, the need to develop more complex and critical analyses of green marketing practices is addressed through the development of a practice theory approach to green marketing. Drawing on an ethnographic study of the Nordic Nature Shop,

The influence of predator regime on the behaviour and mortality of a freshwater amphipod, Gammarus pulex

In species with restricted dispersal, traits may become genetically fixed leading to local adaptations. Therefore, predator avoidance in a prey species may differ between populations experiencing different predator regimes, but also between sexes within a population due to different vulnerability to predators. In this study we used male and female Gammarus pulex from two different predator regimes

Eltoprazine counteracts l-DOPA-induced dyskinesias in Parkinson's disease: a dose-finding study.

In advanced stages of Parkinson's disease, serotonergic terminals take up l-DOPA and convert it to dopamine. Abnormally released dopamine may participate in the development of l-DOPA-induced dyskinesias. Simultaneous activation of 5-HT1A and 5-HT1B receptors effectively blocks l-DOPA-induced dyskinesias in animal models of dopamine depletion, justifying a clinical study with eltoprazine, a 5-HT1A/

Possible future changes in cyclonic storms in the Bay of Bengal, India under warmer climate

The aim of this paper is to study the model's simulated frequency, track, intensity and location of cyclonic storms (CSs) and severe cyclonic storms (SCSs) in the Bay of Bengal (BoB), India. For the purpose, the PRECIS (Providing REgional Climates for Impacts Studies) a regional climate modelling system, of UK Met Office, is used. This model is integrated for the period 1961-1990 (baseline) and th

Normalyzer: A Tool for Rapid Evaluation of Normalization Methods for Omics Data Sets

High-throughput omics data often contain systematic biases introduced during various steps of sample processing and data generation. As the source of these biases is usually unknown, it is difficult to select an optimal normalization method for a given data set. To facilitate this process, we introduce the open-source tool "Normalyzer". It normalizes the data with 12 different normalization method

DNA with double-chained amphiphilic counterions and its interaction with lecithin.

Complex salts of double-stranded DNA with amphiphilic counterions offer novel opportunities for studies of DNA-lipid interactions. Here the effect of the hydrophobicity of the amphiphilic counterion is in focus. For this purpose, double stranded DNA with didodecyldimethylammonium ions as counterions, DDADNA, is prepared and investigated with respect to microstructure. In particular, in order to mo

Analysis of polysaccharide and proteinaceous macromolecules in beer using asymmetrical flow field-flow fractionation

This paper demonstrates the potential of asymmetrical flow field flow fractionation coupled with online multi-angle light scattering, differential refractive index and UV detection for the fractionation and analysis of macromolecules in beer regarding their composition, molar mass (M) and relative concentration. The macromolecules in the liquid and foam of two types of beer, light lager and porter

Self-efficacy beliefs in mathematics, native language literacy and foreign language amongst boys and girls with and without mathematic difficulties

The aim was to examine achievement and self-efficacy in mathematics and native and foreign language literacy in children with specific mathematic LD (MD-only), children with comorbid mathematic and reading difficulties (MD-RD), and compare them with Q6 children without LD (controls), as well as to explore gender differences. Participants were 143 fifth-graders in Sweden who completed National Test

Obstetric outcome in singletons after in vitro fertilization with cryopreserved/thawed embryos

There is increasing use of cryopreservation in IVF. This study compared singletons born after cryopreservation with singletons born after fresh IVF cycles and singletons born to women in the general population. Data were collected for Swedish IVF treatments during the years 20022006. All singletons from single embryo transfer (SET) and double embryo transfer (DET) after cryopreserved (n 2348) and

Circulating CD40+ and CD86+ B Cell Subsets Demonstrate Opposing Associations With Risk of Stroke.

Accumulating evidence shows that immune cells play an important role in atherosclerosis. Most attention has focused on the role of different T cell subsets, whereas the possible involvement of B cells has been less studied. In this study, we assessed the association of 2 different B cell subsets, CD19(+)CD40(+) and CD19(+)CD86(+) B cells, with risk for development of acute cardiovascular events.

A transmission line method for evaluation of vertical InAs nanowire contacts

In this paper, we present a method for metal contact characterization to vertical semiconductor nanowires using the transmission line method (TLM) on a cylindrical geometry. InAs nanowire resistors are fabricated on Si substrates using a hydrogen silsesquioxane (HSQ) spacer between the bottom and top contact. The thickness of the HSQ is defined by the dose of an electron beam lithography step, and
