Abstract in Chinese 概述 学校教学最重要目的之一是赋予每个孩子同等的教育. 尽管如此, 学校再创造了社会差异. 先前的研究表明,学生的低下社会经济情况背景与自然学科成绩低下有一定联系. 这样, 不少学生在未来就被排斥在社会高端学科的教育和职业之外. 本篇论文在Bourdieu和Bernstein的理论基础上, 以自然学科课堂的社会阶级为中心, 旨在对小 学生所受的教育存在不等现象提供更多方位描述和更深层的分析. 在人种民族学的启发下, 本论文的数据取自瑞典义务小学八年级物理教室里的观察, 记录, 采访和统计调查. 1. 对教室里现象的描述和分析揭示了知识难度的下降. 这一现象的发生通常是因为自然学科的教学所具有的社会历史传统因素, 学生, 老师和教室里的谈话社交之间有无形的默契, 或被称为隐蔽的磋商, (出发点往往是善良的愿望),教室里形成了对所有学生都不利的知识难度的The overall aim of this thesis was to contribute to a more complex and multi-faceted description and analysis of inequalities in education, focusing on social class in the science classroom. Inspired by an ethnographic approach, the data was produced through observations, field notes, interviews, and a questionnaire in a Swedish compulsory school. The students aged fourteen and fifteen, were follo

In this paper I discuss two surprising facs in Swedish grammar, the presence of a particular active verb form, the supine, after auxiliary have in perfect and pluperfect, and the free word order found in the middle fielld of main clauses. The supine is not found in any other Germanic language, and is presumably to be seen as a result of a historical coincidence. The free word order in the middle f

En aktieägare i ett tillgångsägande aktiebolag, som vill få egenhändig kontroll över en tillgångs avkastningsförmåga, har idag två möjliga vägar att välja mellan för att uppnå sitt mål. Denne kan förvärva aktier i bolaget eller förvärva, direkt eller indirekt, själva tillgången. Beroende på vilken väg som väljs kommer aktieägaren stöta på olika typer av hinder.

He or she can either acquire shares in the company or directly or indirectly acquire the asset itself. Depending on the chosen path, the shareholder will encounter different types of obstac

The identification of a permanent establishment is the principle used by the Member States of the European Union to determine whether a company is subject to the tax jurisdiction of a State. In the digital context, the notion of permanent establishment is often questioned by States, as companies can provide services remotely without having any physical presence in the territory of a State. This th

This thesis investigates the role of marijuana use in labor productivity in the United States with the aim to contribute to the discussion and understanding of economic consequences of marijuana legalization. The data is sourced from various federal agencies to create a panel of 50 U.S. states and the District of Columbia for the period of 2005-2017. A panel data model with fixed effects is estima

Covert surveillance officers lack special equipment to carry their essential tools during their surveillance jobs. Officers were interviewed about scenarios, needs and the current equipment as well as solutions. It was apparent that it could be problematic to carry essential tools in an organized and concealed way. A generic bag that anyone could carry without looking out of place was developed th

Myanmar has made some reforms in the last couple of years but still the country is facing many difficulties. The aim of this paper is to see how the authorities in Myanmar report about the violence that has been directed towards the country’s Muslim population. This is done through a critical discourse analysis of the state-controlled newspaper The New Light of Myanmar. The findings suggest that t

The normal approach to digital control is to sample periodically in time. Using an analog of integration theory we can call this Riemann sampling. Lebesgue sampling or event based sampling is an alternative to Riemann sampling. It means that signals are sampled only when measurements pass certain limits. In this paper it is shown that Lebesgue sampling gives better performance for some simple syst

A circular polarization selective structure (CPSS) reflects one handedness of circular polarization and transmits the other. We present a new multilayer structure with significantly improved bandwidth compared to classical solutions, which are typically based on resonant structures. The proposed structure consists of layers of printed metal meander lines interspaced by low-permittivity rigid foams

An absolute measure of the fat content in various organs is an important part of diagnostics in obesity and diabetes. Fat quantification using MR-imaging is a non-invasive technique which provides both quantitative and spatial information on fat accumulation. However, for absolute quantification, it is necessary to address the various sources of contrast in MR-imaging. This paper summarizes basic

We predict that in a narrow gap III-V semiconductor quantum well or quantum wire, an observable electron spin current can be generated with a time-dependent gate to modify the Rashba spin-orbit coupling constant. Methods to rectify the so generated ac current are discussed. An all-electric method of spin-current detection is suggested, which measures the voltage on the gate in the vicinity of a tw
