Weathering the storm: Children’s resilience against bullying and harassment

Resilience is a concept of growing interest in the research field, as well as bullying and quality of life. Resilience has gained rising interest over the past decade because it has capacity for systematically informed prevention and intervention (Elbau et al. 2019). This study looks at data from a former study “Trivsel I Tromsø” with children and adolescence victims to bullying and harassment (N=237) and a control group (N=735). In total (N=952). The pupils that matched the criteria, were from 9 to 16 years, who bullied and/or harassed at the cut off-point 3 or more times a month. The aim of the study was to look for any evidence of resilience within the bullied and harassed group. To assess this The Strenghts and Difficulties Questionnaire (SDQ) were used, and resilience was defined within the children or adolescence who scored in the normal range of total difficulty. Furthermore, KINDLR and the SDQ Pro-social score was used in effort to map out trends of resilience within the dataset. This is followed by regression analyses to sort out which variables had the most resistance towards the negative impacts. Main result of this study shows that 176 (74%) of the pupils were resilient towards the bullying and harassment. A moderate resiliency was considered within the borderline N=35 (14,7%), the last group N=26 (10,9%) were associated with low resilience. Compared to the control group, the most important protective factors were friends, the school environment, and emotional well-being in reducing the negative impacts displayed by the SDQ (with some reservations during overlap issues). The also study notes that physical well-being and self-esteem, and pro-social factors has effects against bullying and suggests that family has an effect in lowering the negative impacts of the bulling and harassment

An improved technique for the decontamination of barrier units contaminated with Bacillus piliformis strains of rat origin

Desinfection of animal units is normally based on the use of aldehydes as desinfectants. This article describes a technique for desinfection of animal units in which the use of glutaraldehyde is supplemented with the use of heat and peracetic acid.This method is, in contrast to the use of aldehydes alone, effective against spores of Bacillus piliformis of rat origin, which is in accordance with in vitro investigations

Relative Productive Value of Land

Location, markets, hard surface roads and other transportation facilities, churches, taxes, schools, and utilities are major factors in the monetary value of land, yet these things do not contribute to the land’s productivity. In this bulletin the only factor considered in determining the agricultural value of land is its productive capacity. The three major factors in the productive value of land are water, climate, and soil. These three factors are the principal ones in crop production. If any one of them is unfavorable to plant growth, it can inhibit or even prevent plant growth regardless of how favorable the other factors may be. Productive capacity of land is no better than that permitted by any one of the three factors. Even if two of the factors are favorable, the land will not produce above the capacity of the third. This paper presents a system whereby the effect of soil, water, and climate upon the productive capacity of land can be more clearly understood and more easily evaluated. Not only can the system be used to evaluate the productive capacity, but also to identify factors which may be lowering the value of the land and to evaluate their relative importance. A number of factors that give value to land are rated. The values presented are average relative values which may need some modification before being applied in a specific locality. The authors have presented a philosophy of land evaluation built around scientific facts. They fully expect the values presented to be modified as further data becomes available – also, that additional graphical relationships will be developed for other quantities which have not been quantitatively evaluated in this presentation. This expansion and modification will come as the influence of these factors on agricultural value of land becomes clearer

Improved Algorithms for Computing the Cycle of Minimum Cost-to-Time Ratio in Directed Graphs

We study the problem of finding the cycle of minimum cost-to-time ratio in a directed graph with n nodes and m edges. This problem has a long history in combinatorial optimization and has recently seen interesting applications in the context of quantitative verification. We focus on strongly polynomial algorithms to cover the use-case where the weights are relatively large compared to the size of the graph. Our main result is an algorithm with running time ~O(m^{3/4} n^{3/2}), which gives the first improvement over Megiddo\u27s ~O(n^3) algorithm [JACM\u2783] for sparse graphs (We use the notation ~O(.) to hide factors that are polylogarithmic in n.) We further demonstrate how to obtain both an algorithm with running time n^3/2^{Omega(sqrt(log n)} on general graphs and an algorithm with running time ~O(n) on constant treewidth graphs. To obtain our main result, we develop a parallel algorithm for negative cycle detection and single-source shortest paths that might be of independent interest

Can foundational economy save regions in crisis?

We perform, to our best knowledge, the first systematic mapping of the foundational economy (FE) at the sub-national level by looking at the FE employment in Swedish regions between 2007 and 2016. We show that the FE itself not only suffered less than traded activities from employment decline during the Great Recession of 2007–2009 but was also a domain of substantial job creation in the post-crisis recovery. At the same time, regions with higher dependence on foundational employment were hit harder during the crisis in terms of overall labour market performance. We demonstrate that it is specific compositions of foundational and traded activities in the regional employment mix that relate differently to regional employment growth in times of crisis and recovery. Jointly, these findings allow us to contribute to the literatures on the FE and regional resilience.publishedVersio
