Impacts of the changing climate on agricultural productivity and food security: Evidence from Ethiopia

Ahmed Bouteska, Taimur Sharif, Faruk Bhuiyan et al. · 2024 · Journal of Cleaner Production

This study investigates the influence of climate change on agriculture productivity and food security in the context of Ethiopia. We use 2011–2020 state level data set of four major seasonal crops of Cash and Food in Ethiopia, namely, barley, wheat, maize, and sorghum. Methodologically, we apply the productivity function and the Ricardian approaches in the modelling for simulating the association of climate change with agriculture productivity. This study documents the interconnectedness among changes in climate, security of food and agriculture, indicating how the prior changes bring the latt

An experimental study on the effects of a simulation game on students’ clinical cognitive skills and motivation

Mary Dankbaar, Jelmer Alsma, Els E. H. Jansen et al. · 2015 · Advances in Health Sciences Education

Simulation games are becoming increasingly popular in education, but more insight in their critical design features is needed. This study investigated the effects of fidelity of open patient cases in adjunct to an instructional e-module on students' cognitive skills and motivation. We set up a three-group randomized post-test-only design: a control group working on an e-module; a cases group, combining the e-module with low-fidelity text-based patient cases, and a game group, combining the e-module with a high-fidelity simulation game with the same cases. Participants completed questionnaires

The role of public and private natural space in children's social, emotional and behavioural development in Scotland: A longitudinal study

Elizabeth Richardson, Jamie Pearce, Niamh Shortt et al. · 2017 · Environmental Research

INTRODUCTION: Poor mental health in childhood has implications for health and wellbeing in later life. Natural space may benefit children's social, emotional and behavioural development. We investigated whether neighbourhood natural space and private garden access were related to children's developmental change over time. We asked whether relationships differed between boys and girls, or by household educational status. METHODS: were modelled to quantify their independent contributions to SDQ score change over time. RESULTS: Private garden access was strongly related to most SDQ domains, while

Factors influencing purchase intention towards consumer-to-consumer e-commerce

M. Dachyar, Liska Banjarnahor · 2017 · Intangible Capital

Purpose: This study explores factors that influence consumer’s purchase intention at three consumer-to-consumer (C2C) e-commerce companies in Indonesia.Design/methodology/approach: 5 Expert opinions are used to determine the indicators of each factor and the Structural Equation Modelling (SEM) method is used to analyze the empirical data of 400 respondents for each company.Findings: It is found different significant factors that influence customer’s purchase intention in each company. Trust and risk are found to be significantly effect purchase intention in Company A. Meanwhile, the other two

Primary Elections and Partisan Polarization in the U.S. Congress

Shigeo Hirano, James M. Snyder, Stephen Ansolabehere et al. · 2010 · Quarterly Journal of Political Science

Many observers and scholars argue that primary elections contribute to ideological polarization in U.S. politics. We test this claim using congressional elections and roll call voting behavior. Many of our findings are null. We find little…

Identification of subclasses of sepsis that showed different clinical outcomes and responses to amount of fluid resuscitation: a latent profile analysis

Zhongheng Zhang, Gensheng Zhang, Hemant Goyal et al. · 2018 · Critical Care

BACKGROUND AND OBJECTIVE: Sepsis is a heterogeneous disease and identification of its subclasses may facilitate and optimize clinical management. This study aimed to identify subclasses of sepsis and its responses to different amounts of fluid resuscitation. METHODS: This was a retrospective study conducted in an intensive care unit at a large tertiary care hospital. The patients fulfilling the diagnostic criteria of sepsis from June 1, 2001 to October 31, 2012 were included. Clinical and laboratory variables were used to perform the latent profile analysis (LPA). A multivariable logistic regr

Emergent patterns of collective cell migration under tubular confinement

Wang Xi, Surabhi Sonam, Thuan Beng Saw et al. · 2017 · Nature Communications

Collective epithelial behaviors are essential for the development of lumens in organs. However, conventional assays of planar systems fail to replicate cell cohorts of tubular structures that advance in concerted ways on out-of-plane curved and confined surfaces, such as ductal elongation in vivo. Here, we mimic such coordinated tissue migration by forming lumens of epithelial cell sheets inside microtubes of 1-10 cell lengths in diameter. We show that these cell tubes reproduce the physiological apical-basal polarity, and have actin alignment, cell orientation, tissue organization, and migrat

Back to the future, disability and the digital divide

Stephen J. Macdonald, John Clayton · 2012 · Disability & Society

The aim of this article is to explore disability and the digital divide using a quantitative methodology. The research investigates what impact digital technologies have had in improving the life-chances for disabled people from deprived neighbourhoods in the northeast of England. The study explores how disabled people engage with digital and assistive technologies in order to overcome disabling barriers and social exclusion. Unfortunately, the analysis found no evidence that digital and assistive technologies had any impact on reducing social exclusion for disabled people. In fact, the resear
