Differential alteration of hippocampal function and plasticity in females and males of the APPxPS1 mouse model of Alzheimer's disease

Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by memory loss and impaired cognitive functions. The higher incidence of AD among women indicates that sex is one of the main risk factor for developing the disease. Using the transgenic amyloid precursor protein × presenilin 1 (APPxPS1) mouse model of AD, we investigated sex inequality with regards to memory capaci

Survival Options, Processes of Change and Structural Transformation : Livelihood diversification among smallholder households in rural Sub-Saharan Africa

The overall objective of this thesis is to understand the role of diversification at household level, its patterns, determinants and effects on rural smallholder farmers in SSA, as well as its implications for the process of structural transformation in SSA. In the thesis, I use a mixed methodology and combine different types of data on rural smallholders in SSA to answer the objectives a review o

The association of mobility disability and weight status with risk of disability pension : A prospective cohort study

BACKGROUND/AIMS: Mobility disability (MD) and obesity are conditions which have been associated with weaker labour market attachment. This study investigates whether the combined burden of MD and obesity increase the risk of disability pension compared with having only one of these conditions (the reference group).METHODS: A nationwide cohort study, based on national surveys made between 1996 and

On the direction of cross-linguistic influence in the acquisition of object clitics in French and Italian

Placement errors of object clitics (OCL) in French have been documented in 2L1 and L2 but not in L1 acquisition (Granfeldt 2012; Hamann & Belletti 2006). In the present study, we investigate whether placement errors of third person singular OCLs may be due to cross-linguistic influence. We exposed successive (L1 French/L2 Italian and L1 Italian/L2 French) and simultaneous (2L1 Italian/French) Placement errors of object clitics (OCL) in French have been documented in 2L1 and L2 but not in L1 acquisition (Granfeldt, 2012; Hamann & Belletti, 2006). In the present study, we investigate whether placement errors of third person singular OCLs may be due to cross-linguistic influence. We exposed bilingual children (successive L1 French/L2 Italian and L1 Italian/L2 French and simultaneous 2

Healthy Ageing in People with Intellectual Disabilities from Managers' Perspective : A Qualitative Study

An increasing number of people with intellectual disability (ID) are reaching older ages today although they experience more health problems than the older population without ID. Leaders in intellectual disability services can greatly influence the conditions for a healthy ageing, and the aim of the present study was to explore healthy ageing in this group from the perspective of the leaders. Inte

Identifying the heterogeneity of COPD by V/P SPECT : A new tool for improving the diagnosis of parenchymal defects and grading the severity of small airways disease

Introduction: Airway obstruction and possible concomitant pulmonary diseases in COPD cannot be identified conventionally with any single diagnostic tool. We aimed to diagnose and grade COPD severity and identify pulmonary comorbidities associated with COPD with ventilation/perfusion single-photon emission computed tomography (V/P SPECT) using Technegas as the functional ventilation imaging agent.

Advocacy Coalition Learning – Biases and Heuristics in Policy Implementation

Policy implementation is a complex process and the theoretical problem has been approached in different ways for a long time. Perspectives have converged around governance, negotiation and adaptation and the learning perspective is increasingly acknowledged. This paper explores how policy implementation may be understood from a learning perspective, affected by universal tendencies for humans to d

Force measurements in stiff, 3D, opaque granular materials

We present results from two experiments that provide the first quantification of inter-particle force networks in stiff, 3D, opaque granular materials. Force vectors between all grains were determined using a mathematical optimization technique that seeks to satisfy grain equilibrium and strain measurements. Quantities needed in the optimization - the spatial location of the inter-particle contact

Non-local rheology of dense granular flows

The rheology of dense granular flows is studied numerically in a shear cell controlled at constant pressure and shear stress, confined between two granular shear flows. We show that a liquid state can be achieved even far below the yield stress, whose flow can be described with the same rheology as above the yield stress. A non-local constitutive relation is derived from dimensional analysis throu

Estimating sparse signals using integrated wide-band dictionaries

In this paper, we present a technique for reducing the size of the dictionary in sparse signal reconstruction by formulating an initial dictionary containing elements that spans bands of the considered parameter space. We allow for the use of this banded dictionary in a first-stage estimation procedure, in which large parts of the parameter space is discarded for further analysis, thereby reducing

Forest-like abstract Voronoi diagrams in linear time

Abstract Voronoi diagrams are a general framework covering many types of concrete diagrams for different types of sites or distance measures. Generalizing a famous result by Aggarwal et al. we prove the following. Suppose it is known that inside a closed domain D the Voronoi diagram V(S) is a tree, and for each subset S'⊂S, a forest with one face per site. If the order of Voronoi regions of V(S) a

Humanitarian supply chain strategies – a review of how actors mitigate supply chain risks

Purpose: The purpose of this paper is to link humanitarian logistics (HL) and supply chain risk management (SCRM) to provide an understanding of risk mitigation strategies that humanitarian organisations use, or could use, to improve their logistics preparedness. Design/methodology/approach: Based on systematic reviews of RMS in SCRM and supply chain strategies (SCS) in HL literature, a framework

Targeting the reactive intermediate in polysaccharide monooxygenases

Lytic polysaccharide monooxygenases (LPMOs) are copper metalloenzymes that can enhance polysaccharide depolymerization through an oxidative mechanism, making them interesting for the production of biofuel from cellulose. However, the details of this activation are unknown; in particular, the nature of the intermediate that attacks the glycoside C–H bond in the polysaccharide is not known, and a nu

Market driving at Bottom of the Pyramid (BoP) : An analysis of social enterprises from the healthcare sector

To date, scholarly understanding of external dimensions of market driving for the purposes of 'societal change' is largely unexplored in both developed and emerging market contexts. This paper uses a multiple case study approach to understand how market driving social enterprises (across the hybrid spectrum) create societal change in emerging markets. By drawing on Scott's (1995) three-part concep

Socioeconomic status and geographical factors associated with active listing in primary care : A cross-sectional population study accounting for multimorbidity, age, sex and primary care

Background: Socioeconomic status and geographical factors are associated with health and use of healthcare. Well-performing primary care contributes to better health and more adequate healthcare. In a primary care system based on patient's choice of practice, this choice (listing) is a key to understand the system. Objective: To explore the relationship between population and practices in a primar
