Impact of Conservation Policies on Households’ Deforestation Decisions in Protected and Open-Access Forests: Cases of Moribane Forest Reserve and Ser…

2022

Tropical deforestation is considered a global priority due to its environmental, social, and economic impacts at international, national, and household levels. Conservation policies constitute one of the pathways to reverse this scenario. This paper examines the influence of forest protection measures on local communities’ livelihood decisions regarding forest clearing. It compares deforestation, access to forest resources, and households’ strategies in protected and open-access forests: the Moribane Forest Reserve (MFR) and Serra Chôa (SCH), two environmentally sensitive areas with different conservation statuses in Manica Province, central Mozambique. Socioeconomic data were collected fro…

Eurobarometer 51.0: The Elderly and Domestic Violence, March-May 1999

2000

This round of Eurobarometer surveys queried respondents on standard Eurobarometer measures, such as whether they attempted to persuade others close to them to share their views on subjects they held strong opinions about, whether they discussed political matters, and what the goals of the European Union (EU) should be. Additional questions focused on the respondents' knowledge of and opinions on the EU, including how well-informed they felt about the EU, what sources of information about the EU they used, and whether their country had benefited from being an EU member. Another major focus of the surveys was elderly people and domestic violence. Respondents were asked whether retired people …

The longitudinal development of employee well-being: a systematic review

2016

This article reports a systematic review of findings on the long-term development of employee well-being, taking into account the effects of time lag, age, and job change. High-quality quantitative empirical studies focusing on employee affective well-being based on the circumplex model and utilizing measurements at more than two points in time were searched from eight databases. The systematic analysis of the 40 studies revealed that the level of employee well-being was generally high but not fixed – instead changes in mean levels over time were typical. In addition, the stability of well-being was found to be relatively low, as the explained variances were below 50%. Age and change of job…

What information should I look for again? : Attentional difficulties distracts reading of task assignments

2019

This large-scale eye-movement study (N = 164) investigated how students read short task assignments to complete information search problems and how their cognitive resources are associated with this reading behavior. These cognitive resources include information searching subskills, prior knowledge, verbal memory, reading fluency, and attentional difficulties. In this study, the task assignments consisted of four sentences. The first and last sentences provided context, while the second or third sentence was the relevant or irrelevant sentence under investigation. The results of a linear mixed-model and latent change score analyses showed the ubiquitous influence of reading fluency on first…

Major loss of coralline algal diversity in response to ocean acidification

2021

[Abstract] Calcified coralline algae are ecologically important in rocky habitats in the marine photic zone worldwide and there is growing concern that ocean acidification will severely impact them. Laboratory studies of these algae in simulated ocean acidification conditions have revealed wide variability in growth, photosynthesis and calcification responses, making it difficult to assess their future biodiversity, abundance and contribution to ecosystem function. Here, we apply molecular systematic tools to assess the impact of natural gradients in seawater carbonate chemistry on the biodiversity of coralline algae in the Mediterranean and the NW Pacific, link this to their evolutionary h…

Macroalgal responses to ocean acidification depend on nutrient and light levels

2015

Ocean acidification may benefit algae that are able to capitalize on increased carbon availability for photosynthesis, but it is expected to have adverse effects on calcified algae through dissolution. Shifts in dominance between primary producers will have knock-on effects on marine ecosystems and will likely vary regionally, depending on factors such as irradiance (light vs. shade) and nutrient levels (oligotrophic vs. eutrophic). Thus experiments are needed to evaluate interactive effects of combined stressors in the field. In this study, we investigated the physiological responses of macroalgae near a CO2 seep in oligotrophic waters off Vulcano (Italy). The algae were incubated in situ …

Developing and testing a discrete event simulation model to evaluate budget impacts of diabetes prevention programs

2020

Type 2 diabetes (T2D) is one of the most rapidly increasing non-communicable diseases worldwide. Lifestyle interventions are effective in preventing T2D but also resource intensive. This study evaluated with discrete event simulation (DES) the relative budget impacts of three hypothetical diabetes prevention programs (DPP), including group-based contact intervention, digital program with human coaching and fully automated program. The data for simulation were derived from research literature and national health and population statistics. The model was constructed using the iGrafx Process for Six Sigma software and simulations were carried out for 10 years. All simulated interventions produc…

Species distributions models may predict accurately future distributions but poorly how distributions change: A critical perspective on model validat…

2023

Aim: Species distribution models (SDMs) are widely used to make predictions on how species distributions may change as a response to climatic change. To assess the reliability of those predictions, they need to be critically validated with respect to what they are used for. While ecologists are typically interested in how and where distributions will change, we argue that SDMs have seldom been evaluated in terms of their capacity to predict such change. Instead, typical retrospective validation methods estimate model's ability to predict to only one static time in future. Here, we apply two validation methods, one that predicts and evaluates a static pattern, while the other measures change…
