Not interesting enough to be followed by the NSA: An analysis of Dutch privacy attitudes

Open curtains and a careless attitude. The Dutch are described as holding an indifferent stance towards privacy in the aftermath of Snowden’s revelations of far-reaching government surveillance. But are Dutch reactions as aloof as often claimed? This study provides an in-depth overview of privacy attitudes in the Dutch debate about the National Security Agency (NSA) leaks, showing a greater variety of sentiments than anticipated. A qualitative frame analysis and a quantitative descriptive analysis resulted in six frames, which convey distinct privacy attitudes. Online and offline as well as professional and non-journalistic content in the debate displays a different distribution of frames. The frames, ranging from an “End justifies the means” attitude to an anxious fear of an “Orwellian dystopia”, are placed in a larger framework as the research demonstrates the connection to existing theories about privacy and surveillance. Dutch discussions about the NSA revelations often display a trade-off narrative balancing safety against privacy, and include (de)legitimisation strategies. These outcomes are in line with previous studies about mediated surveillance debates, which indicates that privacy attitudes transcend national boundaries. However, the inclusion of user-generated content adds an individual dimension to the existing body of research and reveals a personal perspective on surveillance issues

An integrative approach to quality of life measurement, research, and policy

While Quality of Life (QOL) has long been an explicit or implicit policy goal, adequate definition and measurement have been elusive. Diverse objective and subjective indicators across a range of disciplines and scales, and recent work on subjective well-being (SWB) surveys and the psychology of happiness have spurred renewed interest. Drawing from multiple disciplines, we present an integrative definition of QOL that combines measures of human needs with subjective well-being or happiness. QOL is proposed as a multiscale, multi-dimensional concept that contains interacting objective and subjective elements. We relate QOL to the opportunities that are provided to meet human needs in the forms of built, human, social and natural capital (in addition to time) and the policy options that are available to enhance these opportunities. Issues related to de?ning, measuring, and scaling these concepts are discussed, and a research agenda is elaborated. Policy implications include strategies for investing in opportunities to maximize QOL enhancement at the individual, community, and national scales

1H NMR structural and functional characterisation of a cAMP-specific phosphodiesterase-4D5 (PDE4D5) N-terminal region peptide that disrupts PDE4D5 interaction with the signalling scaffold proteins, βarrestin and RACK1

The unique 88 amino acid N-terminal region of cAMP-specific phosphodiesterase-4D5 (PDE4D5) contains overlapping binding sites conferring interaction with the signaling scaffold proteins, βarrestin and RACK1. A 38-mer peptide, whose sequence reflected residues 12 through 49 of PDE4D5, encompasses the entire N-terminal RACK1 Interaction Domain (RAID1) together with a portion of the βarrestin binding site. 1H NMR and CD analyses indicate that this region has propensity to form a helical structure. The leucine-rich hydrophobic grouping essential for RACK1 interaction forms a discrete hydrophobic ridge located along a single face of an amphipathic α-helix with Arg34 and Asn36, which also play important roles in RACK1 binding. The Asn22/Pro23/Trp24/Asn26 grouping, essential for RACK1 interaction, was located at the N-terminal head of the amphipathic helix that contained the hydrophobic ridge. RAID1 is thus provided by a distinct amphipathic helical structure. We suggest that the binding of PDE4D5 to the WD-repeat protein, RACK1, may occur in a manner akin to the helix–helix interaction shown for Gγ binding to the WD-repeat protein, Gβ. A more extensive section of the PDE4D5 N-terminal sequence (Thr11-Ala85) is involved in βarrestin binding. Several residues within the RAID1 helix contribute to this interaction however. We show here that these residues form a focused band around the centre of the RAID1 helix, generating a hydrophobic patch (from Leu29, Val30 and Leu33) flanked by polar/charged residues (Asn26, Glu27, Asp28, Arg34). The interaction with βarrestin exploits a greater circumference on the RAID1 helix, and involves two residues (Glu27, Asp28) that do not contribute to RACK1 binding. In contrast, the interaction of RACK1 with RAID1 is extended over a greater length of the helix and includes Leu37/Leu38, which do not contribute to βarrestin binding. A membrane-permeable, stearoylated Val12-Ser49 38-mer peptide disrupted the interaction of both βarrestin and RACK1 with endogenous PDE4D5 in HEKB2 cells, whilst a cognate peptide with a Glu27Ala substitution selectively failed to disrupt PDE4D5/RACK1 interaction. The stearoylated Val12-Ser49 38-mer peptide enhanced the isoprenaline-stimulated PKA phosphorylation of the β2-adrenergic receptors (β2AR) and its activation of ERK, whilst the Glu27Ala peptide was ineffective in both these regards

Quality Measurement in Cancer Care Delivery.

During the past decade, increasing emphasis has been placed on defining and measuring the quality of health care delivery. The Outcomes Committee of the Society of Surgical Oncology (SSO) was established in 2008 to explore and promote emerging outcomes-related topics that are most relevant to society membership. In recognition of the importance of health care quality, a mini-symposium was held at the SSO\u27s 63rd Annual Cancer Symposium in St. Louis, Missouri, in March 2010. The primary objective of the symposium was to define what constitutes quality measurement in cancer care. This article presents an overview of the symposium proceedings

Utilization of neoadjuvant chemotherapy varies in the treatment of women with invasive breast cancer

Background: Treatment with neoadjuvant chemotherapy (NAC) has made it possible for some women to be successfully treated with breast conservation therapy (BCT ) who were initially considered ineligible. Factors related to current practice patterns of NAC use are important to understand particularly as the surgical treatment of invasive breast cancer has changed. The goal of this study was to determine variations in neoadjuvant chemotherapy use in a large multi-center national database of patients with breast cancer. Methods: We evaluated NAC use in patients with initially operable invasive breast cancer and potential impact on breast conservation rates. Records of 2871 women ages 18-years and older diagnosed with 2907 invasive breast cancers from January 2003 to December 2008 at four institutions across the United States were examined using the Breast Cancer Surgical Outcomes (BRCASO) database. Main outcome measures included NAC use and association with pre-operatively identified clinical factors, surgical approach (partial mastectomy [PM] or total mastectomy [TM]), and BCT failure (initial PM followed by subsequent TM). Results: Overall, NAC utilization was 3.8%l. Factors associated with NAC use included younger age, pre-operatively known positive nodal status, and increasing clinical tumor size. NAC use and BCT failure rates increased with clinical tumor size, and there was significant variation in NAC use across institutions. Initial TM frequency approached initial PM frequency for tumors >30-40mm; BCT failure rate was 22.7% for tumors >40mm. Only 2.7% of patients undergoing initial PM and 7.2% undergoing initial TM received NAC. Conclusions: NAC use in this study was infrequent and varied among institutions. Infrequent NAC use in patients suggests that NAC may be underutilized in eligible patients desiring breast conservation
