Most research on corporate responsibility ( CR ) has investigated from the perspective of organizations, often focusing how organizations define, manage and implement to gain benefits or competitive advantage. The for are, however, said be achieved through increased support stakeholders. Despite this, limited attention been given understanding stakeholders and, in particular, mechanism by which drives stakeholder support. This study addresses this deficit. Building advances application...
Background Preclinical models of pediatric cancers are essential for testing new chemotherapeutic combinations clinical trials. The most widely used genetic model preclinical neuroblastoma is the TH-MYCN mouse. This neuroblastoma-prone mouse recapitulates many features human neuroblastoma. Limitations this include low frequency bone marrow metastasis, lack information on whether gene expression patterns in system parallels neuroblastomas, relatively slow rate tumor formation and variability...
Cranial radiotherapy (CRT) is a known risk factor for neurocognitive impairment in survivors of childhood cancer and may increase mild cognitive dementia adulthood. We performed cross-sectional evaluation acute lymphoblastic leukemia (ALL) treated with 18 Gy (n = 127) or 24 138) CRT. Impairment (age-adjusted score >1 standard deviation below expected mean, two-sided exact binomial test) on the Wechsler Memory Scale IV (WMS-IV) was measured. A subset 85) completed structural functional...
This paper links Corporate Governance, Reputation and Responsibility through an examination of stakeholder relationships. It argues that a focus on relationships will allow directors to manage the issues relating these complex areas in practical way. Definitions are as follows: governance is seen be concerned with mechanism by which businesses’ directed controlled. views business key terms relationship issues. way conducts its activities particular how it relates primary secondary...
Abstract A novel two‐element, catheter‐based phased array coil was designed and built for both active MR device tracking high‐resolution vessel wall imaging. The consists of two independent solenoid coils that are wound in opposite directions, connected to separate receive channels, mounted collinearly on an angiographic catheter. elements were used independently or together imaging applications, respectively. array's dual functionality tested a clinical 1.5 T MRI scanner vitro, vivo, situ....
<h3>BACKGROUND AND PURPOSE:</h3> Focal anaplasia characterized by T2 hypointensity, signal-intensity enhancement on postcontrast T1-weighted MR imaging and restricted water diffusion has been reported in a patient with juvenile pilocytic astrocytoma. We identified T2<sub>HOF</sub> these characteristics children DIPG hypothesized that represent areas of focal anaplasia; may, therefore, have increased perfusion properties should be perfusion. Thus, we used DSC to investigate our hypothesis....
Innovation is indisputably one of the most important strategic and operational levers available to managers for creating competitive advantage. Recent studies suggest that there remains a serious disconnect between what firms are hoping for, they, in fact, reaping from their investments innovation. Conventional approaches performance measurement have as yet had little impact area innovation management. The purpose research reported this paper has been address some more pertinent many...
The concept of corporate responsibility (CR) has moved a long way over the past six decades, since Bowen’s book titled Social Responsibilities Businessman marked modern era business and society research. In this article, we trace development literature to provide contextual background contemporary studies CR. As well as looking backward, however, also project forward arguing that fundamental changes in current environment are likely propel CR new heights future. particular, explore...
Purpose Hepatic iron content (HIC) quantification via transverse relaxation rate (R2*)‐MRI using multi‐gradient echo (mGRE) imaging is compromised toward high HIC or at higher fields due to the rapid signal decay. Our study aims presenting an optimized 2D ultrashort time (UTE) sequence for R2* overcome these limitations. Methods Two‐dimensional UTE was realized half‐pulse excitation and radial center‐out sampling. The includes chemically selective saturation pulses reduce streaking artifacts...
Objective Giant cell arteritis (GCA) is characterized by cranial ischemia at diagnosis and late aortic structural disease. Repeated combined large‐vessel fluoro‐2‐deoxyglucose (FDG) positron emission tomography (PET)/computed (CT) scans were performed to assess the distribution of vasculitis activity over time relationship with clinical outcomes. Methods Patients eligible if they enrolled in a 64‐patient inception suspected GCA cohort 2016 2017 had positive temporal artery biopsy and/or...
Abstract In this contribution, a rapid and robust technique for quantitative T 1 mapping of the human lung is presented. Based on series Snapshot FLASH tomograms acquired after single inversion pulse, high quality parameter maps in under five seconds were obtained from six healthy volunteers. The measured values are good agreement with previously reported literature values. also volunteers breathing room air or 100% O 2 . difference between statistically significant at P < 0.0001. J....
Abstract A novel method is presented to simultaneously measure the permeability surface area product of water (PS), also known as capillary diffusion capacity, and regional blood volume (RBV). It based on magnetic resonance imaging longitudinal relaxation times tissue at different concentrations an intravascular MR contrast agent. PS RBV were measured in vivo regions brain skeletal muscle rat. The average values ( n = 5) obtained cerebral cortex, corpus callosum, hippocampus, thalamus, jaw...
A large body of academic literature is concerned with the conceptualisation and measurement Corporate Reputation. However, it not clear how different conceptualisations interact, complement or conflict each other. Moreover, theoretical rigour individual models Reputation always clear. In recent years, there has been a call for development to provide framework that can be used identify scope potential utility measures. This paper answers this by providing integrates analysing as concept...
We are developing methods to characterize atherosclerotic disease in human carotid arteries using multiple MR images having different contrast mechanisms (T1W, T2W, PDW). To enable the use of voxel gray values for interpretation disease, we created a new method, local entropy minimization with bicubic spline model (LEMS), correct severe (approximately 80%) intensity inhomogeneity that arises from surface coil array. This entropy-based method does not require classification and robustly...
Cardiac failure from myocardial iron deposition is a severe complication in patients with transfusion-related overload. Progressive heart damage overload can cause left ventricular systolic and diastolic dysfunction hematologic disorders. Since nontransfused sickle cell anemia (SCA) have high incidence of dysfunction, we investigated the relationships among transfusional burden, deposition, by T2*-MRI tissue Doppler echocardiography iron-overloaded children SCA.Children (> or =7 years) SCA...
Abstract Climate change is a major strategic issue for firms that also has global environmental, social and economic implications. This paper draws upon quantitative survey research to examine the drivers outcomes of corporate commitment climate action in European high emitting industry. More specifically, this examines significance business drivers, sustainability stakeholder pressure, motivating such It furthermore assesses relationships between actual greenhouse gas (GHG) performance....
Abstract Purpose To examine the sensitivity of quantitative dynamic contrast enhanced MRI (DCE‐MRI) perfusion maps to errors in various source images and determine optimal imaging parameters for reducing this sensitivity. Materials Methods A detailed analysis precision a DCE‐MRI protocol was performed using “propagation errors” technique investigate effect on K trans . Optimal parameter values interactions between were examined. The propagation validated by Monte‐Carlo simulations. Results...
This article takes positive psychology concepts from the domain of individual and applies them to workplace. The adaptation Approaches Happiness Questionnaire (Seligman, 2002), developed by Martin Seligman, suggests that three dimensions pleasure, engagement meaning are relevant employees in organisational context. In addition, Seligman´s (2002) classification Character Strengths Virtues is explored, their relevance for workplace performance discussed. paper concludes suggesting a useful...
