Effect of Predatory Stress on Sucrose Intake and Behavior on the Plus-Maze in Male Mice
1999
In this study, the effect of the exposure of male mice to sensory stimuli from rats was assessed on both sucrose intake and the elevated plus-maze tests. CDl male mice were trained in the sucrose intake task (the prestress phase) and, subsequently, distributed into two groups. The stressed group was accommodated in the same room as rats and the control group with mice (the stress phase). After being transferred, animals were tested on sucrose intake and the plus-maze (acute tests) and retested three times a week for sucrose intake and once on plus-maze on the last day (chronic tests). After acute exposure to the predator, the only difference between stressed and control animals was a higher…
Bupropion induces social anxiety in adolescent mice: Influence of housing conditions
2016
Abstract Background The antidepressant bupropion has received increasing attention as a pharmacological tool to treat addiction although little is known about its effects on social behaviour in adolescents. The present study aimed to evaluate if environmental housing conditions influence bupropion’s actions on social behaviour of adolescent mice. Methods Mice were either group- or individually housed for 2-weeks and then randomly divided into 2 cohorts: half of the mice remained in the initial housing condition and the other half were changed to isolated conditions for further 2-weeks. The following groups were compared: isolated/isolated (ISO/ISO), isolated/group-housed (ISO/GR), group-hou…
Endogenous oxytocin is essential for the buffering effects of pair housing against the increase in cocaine reward induced by social stress.
2019
Social factors have a dual influence on addictive disorders. While social defeat stress in rodents increases the response to drug reward, positive social conditions, such as pair housing, increase stress resilience. The objective of the present study was to confirm whether oxytocin (OT) mediates this social buffering. To this end, male mice were housed in pairs and administered the OT receptor antagonist atosiban prior to each stress episode or for ten days after the stress protocol. The response to cocaine was assessed using a conditioned place preference paradigm. Our results confirmed that OT activity mediates the protective effect of pair housing and highlights its therapeutic potential.
Mass appraisal of residential real estate using multilevel modelling
2016
Mass appraisal, or the automatic valuation of a large number of real estate assets, has attracted the attention of many researchers, who have mainly approached this issue employing traditional econometric models such as Ordinary Least Squares (OLS). However, this method does not consider the hierarchical structure of the data and therefore assumes the unrealistic hypothesis of the independence of the individuals in the sample. This paper proposes the use of the Hierarchical Linear Model (HLM) to overcome this limitation. The HLM also gives valuable information on the percentage of the variance error caused by each level in the hierarchical model. In this study HLM was applied to a large dat…
Using a TSP heuristic for routing order pickers in warehouses
2010
In this paper, we deal with the sequencing and routing problem of order pickers in conventional multi-parallel-aisle warehouse systems. For this NP-hard Steiner travelling salesman problem (TSP), exact algorithms only exist for warehouses with at most three cross aisles, while for other warehouse types literature provides a selection of dedicated construction heuristics. We evaluate to what extent reformulating and solving the problem as a classical TSP leads to performance improvements compared to existing dedicated heuristics. We report average savings in route distance of up to 47% when using the LKH (Lin-Kernighan-Helsgaun) TSP heuristic. Additionally, we examine if combining problem-sp…
Extremely low frequency magnetic fields in residences in Germany. Distribution of measurements, comparison of two methods for assessing exposure, and…
2001
We examined the results of 1,835 magnetic field measurements in German residences conducted between November 1997 and September 1999. The measurements were part of an epidemiological study on the relationship between magnetic fields and childhood leukemia. We performed a fixed-location measurement of the magnetic field at 50 Hz and 16 2/3 Hz (frequency of the German railway system) over 24 h in the child's bedroom in the residence of each study participant. In addition, we conducted a second 24 h-measurement in the living room at 50 Hz, and spot measurements while walking through all rooms of the respective dwelling. Median 50 Hz magnetic fields above 0.2 muT were found to be infrequent in …

Evaluation and Quality Assurance in Finnish and Italian Universities in the Bologna Process
2008
Abstract The purpose of the study is to describe the evaluation and quality assurance practices employed in the basic units of Finnish and Italian universities and analyse the impact of the Bologna process on quality assessment. The data consist of interviews (n=30) conducted in Finland and Italy. The results suggest that: (1) evaluation and quality assurance were primarily seen in connection with the educational provision of the university; (2) although the respondents were familiar with evaluation, they were unsure about the procedures and effects of quality assurance in their unit; and (3) despite the harmonising aim of the Bologna process, evaluation, and quality assurance appeared to m…

Geomorphology of the Anthropocene in Mediterranean urban areas
2019
Urban-geomorphology studies in historical cities provide a significant contribution towards the broad definition of the Anthropocene, perhaps even including its consideration as a new unit of geological time. Specific methodological approaches to recognize and map landforms in urban environments, where human-induced geomorphic processes have often overcome the natural ones, are proposed. This paper reports the results from, and comparison of, studies conducted in coastal historical cities facing the core of the Mediterranean Sea – that is, Genoa, Rome, Naples, Palermo (Italy) and Patras (Greece). Their settlements were facilitated by similar climatic and geographical contexts, with high gr…
