Classifying Amharic webnews

We present work aimed at compiling an Amharic corpus from the Web and automatically categorizing the texts. Amharic is the second most spoken Semitic language in the World (after Arabic) and used for countrywide communication in Ethiopia. It is highly inflectional and quite dialectally diversified. We discuss the issues of compiling and annotating a corpus of Amharic news articles from the Web. This corpus was then used in three sets of text classification experiments. Working with a less-researched language highlights a number of practical issues that might otherwise receive less attention or go unnoticed. The purpose of the experiments has not primarily been to develop a cutting-edge text classification system for Amharic, but rather to put the spotlight on some of these issues. The first two sets of experiments investigated the use of Self-Organizing Maps (SOMs) for document classification. Testing on small datasets, we first looked at classifying unseen data into 10 predefined categories of news items, and then at clustering it around query content, when taking 16 queries as class labels. The second set of experiments investigated the effect of operations such as stemming and part-of-speech tagging on text classification performance. We compared three representations while constructing classification models based on bagging of decision trees for the 10 predefined news categories. The best accuracy was achieved using the full text as representation. A representation using only the nouns performed almost equally well, confirming the assumption that most of the information required for distinguishing between various categories actually is contained in the nouns, while stemming did not have much effect on the performance of the classifier.

Crowdfunding as Donations to Entrepreneurial Firms

The bulk of today's (“preorder-,” “reward-,” “gift-,” and “donation-based”) crowdfunding raises funds for small, private entrepreneurial ventures without granting funders private claims to the projects’ income or the ability to guarantee the realization and delivery of project outcomes. We theorize and show empirically – via a mixed-method approach applied to a representative and remarkably informative case – that the payoff structure for crowdfunders, akin to a public good contribution problem, leads to the tangible value of main project outputs exerting little influence on contributions to crowdfunding. This then raises the question of which funder motivations fund seekers may have to address to crowdfund their projects. We demonstrate the especially large role of non-pecuniary motivations and pinpoint three particular motivations that profit-seeking entrepreneurs may stimulate to be financed through crowdfunding. The findings hold important implications for entrepreneurs’ crowdfunding strategies, platform design, and our understanding of how this funding institution works in general. The study also adds to emerging research on the implications of the public good nature of crowdfunding.     

A journey of negotiation and belonging: understanding students’ transitions to science and engineering in higher education

The paper presents results from a longitudinal study of students’ decisions to enrol on a higher education science programme and their experiences of it. The aim is to give insights into students’ transition process and negotiation of identity. This is done by following a cohort of 38 students in a series of qualitative interviews during a 3-year period starting as they were about to finish upper secondary school. We find that the students’ choice of study is an ongoing process of meaning-making, which continues when the students enter higher education and continuously work on their identities to gain a sense of belonging to their science or engineering programme. The use of a narrative methodology provides understanding of choice of study as involving changes in future perspectives and in the interpretation of past experiences. Further, we gain access into how this meaning-making process over time reflects the students’ negotiations in terms of belonging to higher education and their coping strategies when their expectations of their new programme interact with their first-year experiences.

Peer Problems and Hyperactivity–Impulsivity Among Norwegian and American Children: The Role of 5‐HTTLPR

Peer problems are linked to attention deficit hyperactivity disorder (ADHD) symptoms and the serotonin system is thought to be involved in ADHD‐related behavior. Hence, from a Gene × Environment perspective, the serotonin transporter 5‐HTTLPR may play a moderating role. In two large community samples, the moderating role of 5‐HTTLPR was examined related to more hyperactivity–impulsivity symptoms (HI symptoms) predicted by more peer problems. In Study 1, involving 642 Norwegian children, results indicated that for s‐allele carriers only, caregiver‐reported peer problems at age 4 predicted more parent‐reported HI symptoms at age 6. In Study 2, similar results emerged involving 482 American children. Discussion focuses on differential sensitivity to the adverse effects of poor peer relations.     

Emotional Over- and Undereating in Children: A Longitudinal Analysis of Child and Contextual Predictors

Eating more or eating less in response to negative emotions, called emotional over- and undereating, is common in children, but research on the etiology of these behaviors is in its infancy. Drawing on a large, representative community sample of Norwegian children followed up on a biennial basis from 6 to 10 years of age (analysis sample: n = 802), child and contextual predictors (i.e., child temperament, depression symptoms, serious life events, family functioning, parental sensitivity and structuring) of change in emotional over- and undereating were examined. Results revealed that low (temperamental) soothability and less parental structuring at age 6 predicted increased emotional overeating at age 10 and that lower family functioning at age 6 predicted more emotional undereating during the same period.     

Swedish Schools The National Action Programme for ICT in

The National Action Programme, for information and communication technologies in the classroom is a unique effort by the Government to help safeguard equivalent standards and quality between schools. The national curricula adopted in 1992 prescribes a change of focus from teaching to learning. In this change ICT can be a powerful tool for learning and as such promote the transition. Evaluations of ICT projects in schools provide strong evidence that only when the organisation of work has been changed can the introduction of ICT fully support the children's learning. Le programme d’action national pour les TIC dans les écoles suédoises. Le programme national d'action pour les TIC dans les classes constitue de la part du Gouvernement une tentative unique pour maintenir des standards et une qualité équivalente entre les écoles. Le curriculum national adopté en 1992 prescrit un changement d'intérêt – de point de vue – de l'enseignement vers l'apprentissage. Les TIC peuvent devenir un outil particulièrement efficace pour soutenir l'apprentissage et peuvent donc jouer un rÔle important dans cette évolution. Les évaluations des projets d'école intégrant les TIC mettent cependant en évidence le fait que l'introduction des TIC ne soutient réellement l'apprentissage que si l'organisation du travail a elle aussi été changée.
