Review of Sherry Turkle’s ‘Simulation and Its Discontents’
Review of Matthew Hindman’s ‘The Myth of Digital Democracy’
The effect of individual enabling and support on empowerment and depression severity in persons with affective disorders : outcome of a randomized control trial
Purpose: To evaluate the effect of Individual Enabling and Support (IES) on empowerment and depression severity as compared to Traditional Vocational Rehabilitation (TVR) in people with affective disorders at 12 months follow-up. Additionally, longitudinal changes within the intervention groups and the correlation over time between empowerment and depression severity were evaluated. Method: A sing
Decreased global myocardial perfusion at adenosine stress as a potential new biomarker for microvascular disease in systemic sclerosis : A magnetic resonance study
Background: Patients with systemic sclerosis (SSc) have high cardiovascular mortality even though there is no or little increase in prevalence of epicardial coronary stenosis. First-pass perfusion on cardiovascular magnetic resonance (CMR) have detected perfusion defects indicative of microvascular disease, but the quantitative extent of hypoperfusion is not known. Therefore, we aimed to determine
Abstract P2-03-01: Analytical validation of a standardized scoring protocol for Ki67 assessed on breast excision whole sections: An international multicenter collaboration
Aims: (i) Determine whether between-observer reproducibility for Ki67 when assessed on whole sections according to a standardized scoring protocol is adequate for clinical application. (ii) Compare between-observer reproducibility of Ki67 scores assessed on hot-spots to scores using a global method that averages across a tissue section.Background: The nuclear proliferation biomarker Ki67 has multi
Policies or Prices? A Gendered Analysis of Drivers of Maize Production in Malawi and Zambia, 2002–13
Search for sleptons in e+e- collisions at √s = 183 to 189 GeV
Data taken by the DELPHI experiment at centre-of-mass energies of 183 GeV and 189 GeV with a total integrated luminosity of 212 pb-1 have been used to search for the supersymmetric partners of the electrons, muons, and taus in the context of the Minimal Supersymmetric Standard Model (MSSM). The decay topologies searched for were the direct decay (ℓ̃ → ℓx̃), producing acoplanar lepton pairs plus mi
Obese children aged 4–6 displayed decreased fasting and postprandial ghrelin levels in response to a test meal
Aim: Ghrelin is a hunger hormone that plays a role in glucose homoeostasis and its levels increase before a meal and decrease during and after eating. This study compared the fasting ghrelin and insulin levels of obese children aged 4–6 with those of normal weight children and tested postprandial ghrelin levels in the obese children after a standard breakfast. Methods: We recruited 67 children at
Causal cognition, force dynamics and early hunting technologies
With this contribution we analyze ancient hunting technologies as one way to explore the development of causal cognition in the hominin lineage. Building on earlier work, we separate seven grades of causal thinking. By looking at variations in force dynamics as a central element in causal cognition, we analyze the thinking required for different hunting technologies such as stabbing spears, throwi
Advancement towards the scholarship of teaching and learning through the writing of teaching portfolios
This study explores the impact academic teachers’ writing of a teaching portfolio can have on their professional learning. Through an open-ended questionnaire, 26 academics from three faculties reported on insights, effects on teaching practice, and effects on collegial exchange that the portfolio writing entailed. We discuss how the experienced impact relates to the three competence levels excell
Serum and gene expression levels of CT-1, IL-6, and TNF-α after a lifestyle intervention in obese children
Background: Inflammation related molecules such as tumor necrosis factor-α (TNF-α), interleukin 6 (IL-6), and cardiotrophin-1 (CT-1) are highly expressed in obese individuals and could partly explain some comorbidities associated to obesity. In obese children, lifestyle interventions are able to lower inflammation and reduce cardiovascular risk factors associated with obesity. The aim of the prese
Neural and head induction by Insulin-like growth factor signals
Evidence is presented for a new pathway participating in anterior neural development. It was found that IGF binding protein 5 (IGFBP-5), as well as three IGFs expressed in early embryos, promoted anterior development by increasing the head region at the expense of the trunk in mRNA-injected Xenopus embryos. A secreted dominant-negative type I IGF receptor (DN-IGFR) had the opposite effect. IGF mRN
Comparative membrane-associated proteomics of three different immune reactions in potato
Plants have evolved different types of immune reactions but large-scale proteomics about these processes are lacking, especially in the case of agriculturally important crop pathosystems. We have established a system for investigating PAMP-triggered immunity (PTI) and two different effector-triggered immunity (ETI; triggered by Avr2 or IpiO) responses in potato. The ETI responses are triggered by
Well-Being of Early-Career Researchers : Insights from a Swedish Survey
Several studies have documented the importance of optimal work situation and the general well-being of early-career researchers (ECRs) for enhancing the academic performance of universities. Yet, most studies focused on specific categories of ECRs, or on specific academic disciplines as well as on specific outcomes. With this study, we recognize the need for a broader sample encompassing different
Systematic Tuning of Fluoro-galectin-3 Interactions Provides Thiodigalactoside Derivatives with Single-Digit nM Affinity and High Selectivity
Symmetrical and asymmetrical fluorinated phenyltriazolyl-thiodigalactoside derivatives have been synthesized and evaluated as inhibitors of galectin-1 and galectin-3. Systematic tuning of the phenyltriazolyl-thiodigalactosides' fluoro-interactions with galectin-3 led to the discovery of inhibitors with exceptional affinities (Kd down to 1-2 nM) in symmetrically substituted thiodigalactosides as we
A possibility for strengthening family life and health : Family members’ lived experience when a sick child receives home care in Sweden
Families often prefer home care to hospital care, and home-care services for ill children are increasing worldwide with limited knowledge of families’ needs during curative and palliative home care. The aim of this study was to elucidate family members’ lived experience when a sick child received home care from county-based primary healthcare services. A descriptive qualitative design was chosen a
Neural Induction in the Absence of Mesoderm: β-Catenin-Dependent Expression of Secreted BMP Antagonists at the Blastula Stage in Xenopus
A growing body of work indicates that neural induction may be initiated prior to the establishment of the gastrula mesodermal organizer. Here, we examine neural induction in Xenopus embryos in which mesoderm induction has been blocked by Cerberus-short, a reagent that specifically inhibits Nodal-related (Xnr) signals. We find that extensive neural structures with cyclopic eyes and brain tissue are
A direct screen for secreted proteins in Xenopus embryos identifies distinct activities for the Wnt antagonists Crescent and Frzb-1
To determine the spectrum of secreted proteins that are present in the extracellular space of early Xenopus embryos, a direct secretion screen was performed. Surprisingly, 24% of previously identified bona fide secretory proteins corresponded to four secreted Wnt antagonists of the same family: frzb-1, sizzled, sfrp-2 and crescent. sfrp-2 and crescent are novel components of the growing cocktail o
