Simulating worst case scenarios and analyzing their combined effect in operational release planning

Operational release planning (ORP) is concerned with assigning human resources to development tasks in software projects such that a defined set of product features can be completed under given constraints. In this paper, we present a simulation-based approach to study the impact of uncertainty. Uncertainty parameters considered in this paper are related to the features themselves (functionality,

Ethical Theories and the Transparency Condition

Following John Rawls, writers like Bernard Williams and Christine Korsgaard have suggested that a transparency condition should be put on ethical theories. The exact nature of such a condition and its implications is however not anything on which there is any consensus. It is argued here that the ultimate rationale of transparency conditions is epistemic rather than substantively moral, but also t

Different responses of myocardial and cerebral blood flow to cord occlusion in exteriorized fetal sheep

Type and duration of fetal asphyxial insult affect the distribution of blood flow to the heart and brain. The purpose of this study was to describe dynamic and quantitative changes in regional myocardial and cerebral blood flow (CBF) during fetal asphyxia induced by total occlusion of the umbilical cord. Eleven exteriorized fetal sheep were subjected to total umbilical cord occlusion and five feta

A standardised approach to the world? IKEA in China

Purpose The aim of this paper is to analyse the marketing strategy in China of the furnishing retailer IKEA in the context of standardisation and adaptation of marketing activities. IKEA’s strategy in China is compared to its corporate strategy throughout the rest of the world. Design/methodology/approach The four P classifications are used as a framework to compare the central marketing strateg

Cooperative effect of angiotensin AT, and endothelin ETA receptor antagonism limits the brain damage after ischemic stroke in rat

Cerebral ischemia results in enhanced expression of smooth muscle cell endothelin and angiotensin receptors in cerebral arteries. We hypothesise that this phenomenon may be detrimental and that acute treatment with a combined non-hypotensive dose of the angiotensin AT, receptor inhibitor candesartan and the endothelin ETA receptor antagonist ZD 1611 reduces the infarct in experimental ischemic str

Long-term risk of cardiovascular disease in Hodgkin lymphoma survivors-Retrospective cohort analyses and a concept for prospective intervention

Previous studies have shown increased cardiovascular mortality as late side effects in Hodgkin lymphoma (HL) patients. This study identifies stratifying risk factors for surveillance and defines concepts for a clinical feasible and noninvasive prospective protocol for intervention of cardiovascular side effects. HL patients diagnosed between 1965 and 1995 (n = 6.946) and their first-degree relativ

The glycosaminoglycan-binding domain of PRELP acts as a cell type-specific NF-kappa B inhibitor that impairs osteoclastogenesis

Proline/arginine-rich end leucine-rich repeat protein (PRELP) is a glycosaminoglycan (GAG)- and collagen-binding anchor protein highly expressed in cartilage, basement membranes, and developing bone. We observed that PRELP inhibited in vitro and in vivo mouse osteoclastogenesis through its GAG-binding domain ((PRELP)-P-hbd), involving (a) cell internalization through a chondroitin sulfate-and anne

Distinct GATA6- and laminin-dependent mechanisms regulate endodermal and ectodermal embryonic stem cell fates

This study investigates the establishment of alternative cell fates during embryoid body differentiation when ES cells diverge into two epithelia simulating the pre-gastrulation endoderm and ectoderm. We report that endoderm differentiation and endoderm-specitic gene expression, such as expression of laminin 1 subunits, is controlled by GATA6 induced by FGF. Subsequently, differentiation of the no

Metabolic fate of C-14-labelled chlorinated and non-chlorinated fatty acids in goldfish (Carassius auratus)

In order to study the metabolic fate of chlorinated fatty acids in fish, goldfish were fed either 9,10-dichlorostearic acid or oleic acid, chosen as the unchlorinated analogue, both radiolabelled at either the carboxyl (1st) or the terminal (18th) carbon of the fatty acid chain. By keeping the fish in hermetically closed aquaria, all the respired, assimilated and excreted radioactivity could be ac

Spectroscopic characterization of intermediate steps involved in donor-side-induced photoinhibition of photosystem II

The reaction center protein D1 in photosystem II shows a high turnover during illumination. The degradation of the DI protein is preceded by photoinhibition of the electron transport in photosystem II. There are two distinct mechanisms for this: acceptor-side- and donor-side-induced photoinhibition. Here, donor-side-induced photoinhibition was studied in photosystem II membranes after Cl- depletio

Magnetoresistance studies on Co/AlOX/Au and Co/AlOX/Ni/Au tunnel structures

We report on magnetoresistance (MR) studies on Co/AlOX/Au and Co/AlOX/Ni/Au magnetic tunnel junctions. In spite of the fact that the difference between the two samples is merely a 3 nm thick Ni layer, there is a sharp contrast in MR behavior indicating that the electronic structure at the interface between the ferromagnetic electrodes and the insulating barrier dominates the MR signal. The former

Prospective study of IGF-I, IGF-binding proteins, and breast cancer risk, in Northern and Southern Sweden

Objective: To examine the possible relationships of breast cancer risk to prediagnostic plasma levels of insulin; insulin-like growth factor-I (IGF-I); and IGF-binding proteins -1, -2, and -3. Methods: Within two prospective cohorts in Umea and Malmo we measured plasma concentrations of insulin, IGF-I, and IGFBPs for a total of 513 incident breast cancer cases and 987 matched controls. Results: Gl

Empirical research methods in software engineering

Software engineering is not only about technical solutions. It is to a large extent also concerned with organizational issues, project management and human behaviour. For a discipline like software engineering, empirical methods are crucial, since they allow for incorporating human behaviour into the research approach taken. Empirical methods are common practice in many other disciplines. This cha

Applet verification strategies for RAM-constrained devices

While bringing considerable flexibility and extending the horizons of mobile computing, mobile code raises major security issues. Hence, mobile code, such as Java applets, needs to be analyzed before execution. The byte-code verifier checks low-level security properties that ensure that the downloaded code cannot bypass the virtual machine's security mechanisms. One of the statically ensured prope

Influence of shock waves on laser-driven proton acceleration

The influence of shock waves, driven by amplified spontaneous emission (ASE), on laser-accelerated proton beams is investigated. A local deformation, produced by a cold shock wave launched by the ablation pressure of the ASE pedestal, can under oblique laser irradiation significantly direct the proton beam toward the laser axis. This can be understood in the frame of target normal sheath accelerat
