Structural defects are detrimental to the efficiency and quality of optoelectronic semiconductor devices. In this work, we study InGaN platelets with a quantum well structure intended for nano-LEDs emitting red light and how their optical properties, measured with cathodoluminescence, relate to the corresponding atomic structure. Through a method of spectroscopy-thinning-imaging, we demonstra

Background:Earlier clinical detection of cancer may improve survival as well as offer opportunities for less invasive treatment options. This thesis explores whether the mitochondria and its related genes in the nuclear genome can be used as novel methods for the diagnosis and prognosis of cancers.Aims and Methods:Paper I: To investigate if mitochondrial dysfunction (characterized by mtDNA copy nu

It is well-known that an ideal extraction method enabling quantitative analysis should give complete extraction of the target analytes as well as minimal co-extraction of unwanted matrix substances. If the extraction method is part of a nontarget screening protocol, the desired analytes can differ widely in terms of chemical properties. In chromatography, terminologies such as recovery, selectivit

I denna rapport redovisar Kerstin Svensson och Monica Larsson (Socialhögskolan, Lunds universitet) ett projekt som tar upp civilsamhällets medverkan i myndigheters arbete då privatpersoner engageras som socialt stöd för medmänniskor. Syftet med projektet är att förstå tanken bakom medborgarmedverkan i myndigheters lagreglerade sociala insatser, hur den har utvecklats och vilka tendenser som finns

Building on Zoltán Dörnyei's authoritative work in the field of learner motivation, this book introduces a new conceptualization-Directed Motivational Currents (DMCs)-and sets out the defining aspects of what they are, what they are not, and how they are related to language learning motivation. Going beyond focused behavior in a single activity, DMCs concern intensive long-term motivation. The dis

In contexts of transnational migration, language skills provide the key to employability and successful integration into host country societies. To enhance the learning process, and facilitate transitions into the workforce, integrated programs of L2 learning have been developed in several Nordic countries. In these undertakings, language learning, vocational education, and workplace practice are

This article describes two inter-related research projects concerned with the teaching and learning of English in contemporary contexts, where English is changing its status from being the first language of specific groups of speakers to becoming a global lingua franca. Focussing respectively on learners of English as a second language (L2 users) in the Netherlands and Sweden, and on native speake

Identity is of increasing interest in teacher education. Crucial for resilience, the development of a coherent professional identity has been characterized as emerging from tensions between multiple and sometimes conflicting conceptions of what it means to be someone who teaches (Akkerman & Meijer, 2011). While light is being shed on these often antagonistic relations, less is known about the

Currently, the inner dynamics of teacher identity transformations remain a “black box.” Conceptualizing preservice teacher identity as a complex dynamic system, and the notion of “being someone who teaches” in dialogical terms as involving shifts between different teacher voices, the study investigates the dynamical processes at play when transitions between identities occur. Using a single-case d

Motivation in simultaneous L2 learning situations is an area of research largely overlooked and studies from contexts where people are engaged in learning more than one L2 are rare. In their large-scale Hungarian research, Dornyei, Csizer and Nemeth found that pupils' positive attitudes to one L2 could cause interferences with attitudes to others, with English being the greatest source of such int
