Teknik på förskolan : Hur pedagoger uppfattar och ser på teknik i förskolan

Syftet med uppgiften är att få kunskap om hur pedagoger uppfattar och ser på teknik i förskolan. För att undersöka detta har jag formulerat följande övergripande frågeställningar: Hur resonerar, uppfattar och ser pedagoger på begreppet teknik?, samt Hur arbetar pedagogerna med teknik i förskolan? Som metod har jag valt semistrukturerade kvalitativa intervjuer som tolkas utifrån fenomenologisk teori och sex pedagoger vid sex olika verksamheter i en kommun har intervjuats. Pedagogerna i studien ser teknikämnet som något positivt och tycker det är kul, men framför att många i deras arbetslag finner en viss rädsla för ämnet. Teknik behöver inte vara svårt och går att fånga i vardagen på förskolan, men det svåra är att medvetandegöra för barnen att de arbetar med teknik. Av studiens resultat framkommer att teknik på förskolorna framför allt är bygg- och konstruktion med olika strukturerade och ostrukturerade material, och att aktiviteter sker främst spontant och äger rum året runt både inomhus och utomhus.

Kvinnans tillit till amning : En enkätstudie på BB och Eftervårdsmottagningen i Värmland

Amningsfrekvensen i Värmland sjunker och är låg jämfört med riket. En bidragande faktor till den sjunkande amningsfrekvensen är bristen på tillit till amning. Det är viktigt att kunna identifiera kvinnor med låg tillit till amning för att vända den sjunkande amningsfrekvensen och stärka kvinnan i rollen som moder. Syfte: Syftet med denna studie var att undersöka kvinnors tillit till amning på Barnbördshuset (BB) och Eftervårdsmottagningen i Värmland. Med enkäten BSES-SF identifieras kvinnor med låg tillit till amning och kvinnor som behöver ett ökat amningsstöd efter förlossning. Design/Metod: Studien utfördes med kvantitativ ansats. Data inhämtades från enkäten BSES-SF som besvarats av 70 kvinnor på BB och Eftervårdsmottagningen i Värmland. All data analyserades genom SPSS. Resultat: De flesta kvinnor ansåg att det var mycket viktigt med en fungerande amning och när kvinnorna skattade amningens betydelse framkom ett medelvärde på 8,66 där 0=inte alls viktigt och 10=mycket viktigt. Kvinnor som ammat tidigare skattade sin upplevda amningserfarenhet som mycket god. Varje enskild fråga på BSES-SF jämfördes mellan kvinnorna som vårdats på BB och Eftervårdsmottagningen. Det framkom en skillnad på åtta frågor där kvinnorna på Eftervårdsmottagningen skattade en högre tillit till amning jämfört med kvinnorna på BB. Utifrån totalsumman på BSES-SF med ett poängintervall mellan 14-70, framkom det att tilliten till amning skattades högre hos kvinnorna på Eftervårdsmottagningen (M=56,54) än på BB (M=49,88). Slutsats och klinisk tillämpbarhet: BSES-SF kan utifrån studiens resultat vara ett användbart verktyg, framförallt på BB där kvinnorna skattat en lägre tillit till amning. Förstföderskor och omföderskor som upplevt en komplicerad förlossning kan vara i behov av större insatser av amningsstöd. Studiens resultat kan medföra att barnmorskan blir extra uppmärksam på de kvinnor vars amning inte fungerar och där extra stöd behövs för att öka tilliten.

Lanseringen och etableringen av ett socialt problem : En analys av debatten om ledarkulturen inom svensk landslagsgymnastik i Dagens Nyheter 2012–2013

The launching and establishment of a social problem: An analysis of the debate on Swedish national level gymnastics in Dagens Nyheter 2012-2013 In 2012 Sweden’s largest daily newspaper, Dagens Nyheter, published a number of articles on the state of affairs in Swedish national level gymnastics. In these articles, ex-gymnasts, coaches, parents and physicians stepped forward and testified about recurrent wrongdoings and abuse against young (particularly) female gymnasts. In response to the criticism, the accused coaches and representatives of the Swedish Gymnastics Federation downsized or dismissed the criticism as inaccurate. This being said, and using discursive psychology and a qualitative design, this article sheds light upon this debate – by viewing it as a struggle between a hegemonic discourse of ”the goodness” of sports, on the one hand, a number of unfavorable and negative testimonies of the state of affairs in Swedish national level gymnastics on the other. More concretely, this struggle has been analyzed with regard to the discursive and rhetoric resources the involved parties’ used to pursue their claims about the state of affairs in Swedish national level gymnastics and the impact these resources had for their credibility and legitimacy. Questions were: Who is entitled ”to spell out” their view on the state of affairs within Swedish national level gymnastics? What is mediated and how? How are descriptions and accounts about reality constructed as credible and factual? It is concluded that social problems are launched via co-production; in this process, the gymnastics community, the research community, single individuals, and the media – were co-actors. 

Parent’s experiences of feeding their preterm infant in Neonatal Units in Sweden. : Ethnographic design

Introduction: Studies have shown that having a preterm infant may cause stress and powerlessness for parents. It is important to support parents around the feeding situation, and that the Neonatal Intensive Care Unit (NICU) has appropriate space and place to help the family to bond to each other. For the healthcare professionals it is important to promote skin-to-skin contact and breastfeeding; particularly for preterm infants. There are many studies on parent’s experiences of NICUs and a few studies on parent’s experiences of feeding their infant in the NICU. Objective: The objective of this study was to explore parents experiences of feeding their infant in the NICU. Design: The study was conducted using an ethnographic design. Results: A global theme of ‘The journey in feeding’ was developed from four organising themes: ‘Ways of infant feeding’; ‘Environmental influences’; ‘Relationships’ and ‘Emotional factors’. These themes illustrate the challenges mothers reported with different methods of feeding. The environment had a big impact on parent’s experiences of infant feeding. Some mothers felt that breastfeeding seemed unnatural because their infant was so tiny but breastfeeding and skin-to-skin contact helped them to bond to their infant. The mothers thought it was difficult to keep up with the milk production by only pumping. Routines were not inviting parents to find their own rhythm. They also felt stressed about the weighing. Healthcare professionals had positive and negative influences on the parents. Conclusions: This study demonstrates that while all parents expressed the wish to breastfeed, their ‘journey in feeding’ was highly influenced by method of feeding, environmental, relational and emotional factors. The general focus upon routines and assessing milk intake generated anxiety and reduced relationality. Midwives and neonatal nurses need to ensure that they emphasise and support the relational aspects of parenting and avoid over-emphasising milk intake and associated progress of the infant

Passive MVC och MVVM designmönster i Android : En jämförelse av kodkomplexitet mellan Passive MVC och MVVM

Det mobila operativsystemet Android är idag ett ganska dominerande operativsystem på den mobila marknaden dels på grund av sin öppenhet men också på grund av att tillgängligheten är stor i och med både billiga och dyra telefoner finns att tillgå. Men idag har Android inget fördefinierat designmönster vilket leder till att varje utvecklare får bestämma själv vad som ska användas, vilket ibland kan leda till onödigt komplex kod i applikationerna som sen blir svårtestad och svårhanterlig. Detta arbete ämnar jämföra två designmönster, Passive Model View Controller (PMVC) och Model View View-Model (MVVM), för att se vilket designmönster som blir minst komplext med hjälp av att räkna fram mätvärden med hjälp av Cyclomatic Complexity Number (CCN). Studien är gjord utifrån arbetssättet Design & Creation och ämnar bidra med: kunskap om vilket mönster man bör välja, samt om CCN kan peka ut vilka delar i en applikation som kommer att ta mer eller mindre lång tid att testa. Under studiens gång tog vi även fram skillnader på om man anväder sig av den så kallade Single Responsibilyt Principle (SRP) eller inte. Detta för att se om separerade vyer gör någon skillnad i applikationernas komplexitet. I slutändan så visar studien på att komplexiteten i små applikationer är väldigt likvärdig, men att man även på små applikationer kan se skillnad på hur komplex koden är men också att kodkomplexitet på metodnivå kan ge riktlinjer för testfall.

Rapport från projektet Multimodala uppgifter och bedömning i matematik : Video och kollaborativa samtal som metod vid lärares bedömning av elevers matematiska kunskaper

This research will discuss some experiences from a four year school research study. It was conducted in cooperation with teachers from four municipalities in Dalarna. The aim of the research was to examine teachers´ professional development when they participated in collaborative discussions based on video recordings and video edited material from specific lessons in their own practice. The study had two foci one was to investigate methods and tools that teachers can use to develop their ability to assess their students while working on multimodal tasks. The other was to examine how video can be used by teachers wanting to obtain knowledge about assessing students. The study is based on several theories about when teachers collaborate to create new knowledge. The first is the design theoretical approach – where visual ethnography and a semiotic approach contribute to problematize the use and mixture of different modes. A basic assumption of the framework here is that meanings are made and communicated in mathematics through a wide range of semiotic modes. By using video as an essential tool in the research the framework theories concerning visual ethnography, video documentation and individuals as reflective practitioners were also needed. The findings can be divided into the following themes: the use of tasks for assessment, collaborative discussion, equipment, ethical dilemmas. Collaborative discussions were evaluated as a meaningful way of sharing knowledge. The use of video recordings in association with these discussions raised important ethical issues. Working with the assessment framework was of great interest to the teachers but it took a lot of time from their ordinary work. In this way the project highlighted more general aspects of school development. The research also concerns teachers´ use of collaborative discussions in assessment work, multimodal tasks in mathematics and video as a research tool in general.

Etikettdesign hos framgångsrika alesorter i Sverige från olika produktionsländer

Föreliggande studie syftar till att kartlägga vilka designfaktorer som främst förekommer på etiketter hos framgångsrika aleproducenter från olika länder, samt undersöka om konsumenter kan urskilja produktionsland endast genom granskning av etiketten. För att undersöka detta genomfördes en visuell innehållsanalys för att ta fram designfaktorer för fem utvalda länder, varefter fem typexempel skapades. Typexemplen testades på konsumenter via en webbenkät. Slutsatsen är att det i vissa fall går att ta fram ett typexempel och i vissa fall kan en del av konsumenterna se vilket det tänkta produktionslandet är. I majoriteten av fallen gick det emellertid inte att ta fram ett perfekt typexempel och konsumenten kunde inte urskilja det tänkta produktionslandet.

Kreativitet under stress : En studie i att vara kreativ på beställning

En grafisk designer måste kunna producera oavsett vilka förhållanden som råder. Rapporten behandlar vad korta och långa deadlines har för inverkan på denna förmåga och hur kreativiteten kan främjas vid stressiga situationer. Semistrukturerade djupintervjuer utfördes med åtta Art- och Creative directors i Gävledala-regionen för att undersöka hur de upplevde att vara kreativa under stressiga förhållanden. Resultatet visade att det generellt inte var ett problem för studiens respondenter att vara kreativa på beställning men att de inte heller följde några specifika metoder för att underlätta arbetsflödet. Det visade sig även att det snarare var arbetsbördan och mängden arbetsuppgifter som påverkade stressfaktorn än en specifik tidsram.

Primitive art as it relates to contemporary design

For the most part, my project has been of an individually rewarding nature due to an extensive amount of reading and studio work. My paper functions as the major means of communication of my own experiences and findings. It is an attempt to share with others the ideas which I have found particularly stimulating and worthwhile during the course of the year. In other words, the written portion does not intend to summarize all of the phases of primitive art which I have studied during the past year; rather, it is indicative of the type of pursuit with which I became involved. It is neither a historical survey nor a specific and thorough study of one area of primitive art. Instead, my paper is a series of essays focusing upon primitive art in general, and upon some of the aspects of primitive art with which I became concerned in particular.

Evaluating And Optimizing Sustainable Drainage Design To Maximize Multiple Benefits: Case Studies In China

In the past, the focus of drainage design was on sizing pipes and storages in order to provide sufficient network capacity. This traditional approach, together with computer software and technical guidance, had been successful for many years. However, due to rapid population growth and urbanisation, the requirements of a “good” drainage design have also changed significantly. In addition to water management, other aspects such as environmental impacts, amenity values and carbon footprint have to be considered during the design process. Going forward, we need to address the key sustainability issues carefully and practically. The key challenge of moving from simple objectives (e.g. capacity and costs) to complicated objectives (e.g. capacity, flood risk, environment, amenity etc) is the difficulty to strike a balance between various objectives and to justify potential benefits and compromises. In order to assist decision makers, we developed a new decision support system for drainage design. The system consists of two main components – a multi-criteria evaluation framework for drainage systems and a multi-objective optimisation tool. The evaluation framework is used for the quantification of performance, life-cycle costs and benefits of different drainage systems. The optimisation tool can search for feasible combinations of design parameters such as the sizes, order and type of drainage components that maximise multiple benefits. In this paper, we will discuss real-world application of the decision support system. A number of case studies have been developed based on recent drainage projects in China. We will use the case studies to illustrate how the evaluation framework highlights and compares the pros and cons of various design options. We will also discuss how the design parameters can be optimised based on the preferences of decision makers. The work described here is the output of an EngD project funded by EPSRC and XP Solutions.

Mixed-signal analog-digital circuits design on the pre-diffused digital array using trapezoidal association of transistors

The mixed-signal and analog design on a pre-diffused array is a challenging task, given that the digital array is a linear matrix arrangement of minimum-length transistors. To surmount this drawback a specific discipline for designing analog circuits over such array is required. An important novel technique proposed is the use of TAT (Trapezoidal Associations of Transistors) composite transistors on the semi-custom Sea-Of-Transistors (SOT) array. The analysis and advantages of TAT arrangement are extensively analyzed and demonstrated, with simulation and measurement comparisons to equivalent single transistors. Basic analog cells were also designed as well in full-custom and TAT versions in 1.0mm and 0.5mm digital CMOS technologies. Most of the circuits were prototyped in full-custom and TAT-based on pre-diffused SOT arrays. An innovative demonstration of the TAT technique is shown with the design and implementation of a mixed-signal analog system, i. e., a fully differential 2nd order Sigma-Delta Analog-to-Digital (A/D) modulator, fabricated in both full-custom and SOT array methodologies in 0.5mm CMOS technology from MOSIS foundry. Three test-chips were designed and fabricated in 0.5mm. Two of them are IC chips containing the full-custom and SOT array versions of a 2nd-Order Sigma-Delta A/D modulator. The third IC contains a transistors-structure (TAT and single) and analog cells placed side-by-side, block components (Comparator and Folded-cascode OTA) of the Sigma-Delta modulator.

Organizational design and incentive provision

We model the trade-off between the balance and the strength of incentives implicit in the choice between hierarchical and matrix or- ganizational structures. We show that managerial biases determine which structure is optimal: hierarchical forms are preferred when biases are low, while matrix structures are preferred when biases are high. Moreover, the results show that there is always a level of bias for which matrix design can achieve the expected profit obtained by shareholders if they could directly control the firm. We also show that the main trade-off, i.e., hierarchical versus matrix structure is preserved under asymmetric levels of bias among managers and when low-level workers perceive activities with complementary efforts.

Europe’s financial crisis: the Euro’s flawed design and the consequences of lack of a government banker

This paper argues the euro zone requires a government banker that manages the bond market and helps finance country budget deficits. The euro solved Europe’s problem of exchange rate speculation by creating a unified currency managed by a single central bank, but in doing so it replaced the exchange rate speculation problem with bond market speculation. Remedying this requires a central bank that acts as government banker and maintains bond interest rates at sustainable levels. Because the euro is a monetary union, this must be done in a way that both avoids favoring individual countries and avoids creating incentives for irresponsible country fiscal policy that leads to “bail-outs”. The paper argues this can be accomplished via a European Public Finance Authority (EPFA) that issues public debt which the European Central Bank (ECB) is allowed to trade. The debate over the euro’s financial architecture has significant political implications. The current neoliberal inspired architecture, which imposes a complete separation between the central bank and public finances, puts governments under continuous financial pressures. That will make it difficult to maintain the European social democratic welfare state. This gives a political reason for reforming the euro and creating an EPFA that supplements the economic case for reform.

Períodos de matocompetição na cultura da soja (Glycine max (L.) Merril), cultivares Santa Rosa e IAC-2. I- efeitos sobre os parâmetros de produção

Visando estudar a influência do período de competição das plantas daninhas sobre alguns parâmetros de produção da cultura da soja, foram instalados experimentos de campo com os cultivares Santa Rosa e IAC-2 em dois tipos de solos, Latossol Roxo e Latossol Vermelho Escuro - fase arenosa, no município de Jaboticabal, Estado de São Paulo, Brasil. O delineamento experimental utilizado foi o de blocos ao acaso , sendo os cultivares mantidos sem e com competição das plantas daninhas por períodos cujas extensões foram 0, 10, 20, 30, 40, 50 e 60 dias após a emergência. Com base nos resultados obtidos, pode-se concluir que: o período mínimo do início do ciclo que deve ser mantido livre de competição é de 30 a 40 dias após a emergência para o cultivar Santa Rosa e de 50 dias para o 'IAC-2'; para os dois cultivares, a produção de grãos foi efetivamente aumentada após o 20.° dia sem competição no solo Latossol Roxo e 30.° dia no solo Latossol Vermelho Escuro - fase arenosa, atingindo um valor máximo no 50.° dia para o 'Santa Rosa' e ao redor do 60.° dia para o 'IAC-2'; no ano agrícola de 1977/78 (solo Latosso l Roxo), a competição durante os primeiros 20 dias após a emergência causou perdas de produção em ambos os cultivares, entretanto, no de 1978/79 (solo Latossol Vermelho Escuro - fase arenosa) este período foi de 40 dias, mostrando a importância das interferências e da foclimáticas e das diferentes espécies daninhas, no processo de competição; e, dentre todos os parâmetros relacionados à produção de grãos, o número de vagens por planta foi o mais afetado pela competição das plantas daninhas.

Integração de práticas culturais e redução da dose do bentazon na cultura da soja: I - efeitos sobre o crescimento da cultura

O trabalho foi desenvolvido no município de Jaboticabal, SP, no ano agrícola de 1990/91, onde testou-se a integração de práticas culturais e menor dose de herbicida aplicado em pósemergência na cultura da soja, cultivar Paraná. O delineamento experimental utilizado foi o de blocos ao acaso, com dezesseis tratamentos e quatro repetições, no esquema fatorial 4x2x2, sendo quatro tipos de manejos de plantas daninhas: testemunha infestada, 50% da dose recomendada (360 g ia/ha) do herbicida bentazon, dose recomendada do herbicida bentazon (720 g ia/ha) e testemunha capinada; dois espaçamentos entre-linhas: 30 cm e 60 cm; e duas densidades: normal e reduzida (média de 20 e 10 plantas por metro, respectivamente). Observou-se que a quantidade de matéria seca das plantas daninhas por época da colheita da soja, foi significativamente maior nos tratamentos com espaçamento maior e densidade reduzida. O arranjo proporcionado pela densidade normal (média de 20 plantas /m) e menor espaçamento (30 cm) entre-linhas, proporcionou sombreamento mais precoce do solo e foi a melhor opção de controle cultural das plantas daninhas em todos os tratamentos testados. Não foi observado sintomas de intoxicação e nem efeitos negativos sobre a nodulação das plantas de soja, por parte do herbicida aplicado, em ambas as doses testadas.
