Making Learning Possible : Nätbaserad utbildning vid Högskolan Dalarna

Högskolan Dalarna (HDa) har gjort ett strategiskt/medvetet val genom att betona den pedagogiska utvecklingen för nästa generations lärande (NGL) och har under flera år utvecklat nätbaserade kurser. NGL centrum är ett nav i den pedagogiska utvecklingen på HDa. Vår roll är att möjliggöra studenters lärande. (Ramsden 2003). Vid vår högskola fokuserar vi på olika datorsystem som stödjer lärandet och möjliggör synkron interaktion och kommunikation, både vid seminarier och under föreläsningar. Vi har valt och utvecklat system som stödjer lärandet och kontakten mellan studenter och lärare på ett bra sätt, fokus ligger inte nödvändigtvis på den nyaste teknologin. Vi anser att det är viktigt att skapa förutsättningar för sociokulturella miljöer vid nätbaserade utbildingar och därför är seminarier och samtal mycket viktiga i våra utbildningar. (Säljö 2000). Vi har definierat tre huvudbehov för lärandeprocessen och vi har valt system för informationsutbyte (Fronter), Adobe Connect för seminarier och Videochat - vårt egenutvecklade system för föreläsningar. Vi vet sedan många år att föreläsningar hjälper studenterna att förstå litteraturen bättre. Ett LMS (Fronter) är ett sätt att samla information såsom scheman och uppgifter. Där sker diskussioner om innehåll och kursupplägg, inlämningar, nyheter och meddelanden. När det gäller föreläsningar har vi valt att använda ”live-streaming” med möjlighet att spela in föreläsningen. Vi betraktar varken Adobe Connect eller vår Videochat som virtuella verktyg. De möten som genomförs med dessa verktyg är på riktigt. Studenter och lärare vittnar ofta om att de interagerar mer i ett seminarium via Connect än vad som sker i en fysisk föreläsningssal och bekräftar den pedagogiska närheten. HDa har system som är säkra men vi tror samtidigt på öppenhet och lättillgänglighet. Vi välkomnar gäster in i systemen för att skapa transparens. Läraren har möjlighet att låsa mappar i vårt LMS och göra dem både säkra och privata. Vi vill berätta och visa för intresserade konferensdeltagare hur vi på Högskolan Dalarna jobbar generellt med nätbaserade verktyg men också visa på mer specifika lösningar som har uppskattats av våra studenter och lärare.   References Ramsden, Paul (2003).

Making learning possible - Nätbaserad utbildning för funktionsnedsatta studenter

Making learning possible - Nätbaserad utbildning för funktionsnedsatta studenter Högskolan Dalarna har gjort ett strategiskt/medvetet val genom att betona den pedagogiska utvecklingen för nästa generations lärande (NGL) och har under flera år utvecklat nätbaserade kurser.  Detta innebär även att ibland måste anpassa våra system för t.ex. hörselskadade studenter. Högskolan har en lång tradition av teckentolka föreläsningar i sal. Vi har även under en längre tid teckentolkat inspelade föreläsningar. Efter att ha provat olika sätt att spela in dessa har vi nu landat i ett system där originalföreläsningen är till vänster och tar upp c:a 80% av skärmen. Teckentolken syns i de resterande 20% till höger. Eftersom vi använder samma system för teckentolkningen som våra lärare har i studion blir det ”strömlinjeformat” då vi bara behöver hantera ett system och får den automatisering som är inbyggd. När det gäller seminarier använder vi oss av Adobe Connect. Lärarna, teckentolken och studenterna (även de hörselskadade) är i ett rum där läraren visar sina dokument, samtalar med studenterna o.s.v.. Teckentolken och den hörselskadade studenten har ett extra rum i Connect där tolken syns. När studenten ska prata så tecknar studenten och det taltolkas av tolken i Connect-rummet med läraren. För detta har teckentolkarna ett separat rum/studio med två skärmar för att kunna se och höra båda Connect-rummen. Vi rekommenderar studenten att också ha två skärmar. Teoretiskt borde detta även kunna användas för en hörselskadad lärare men det har inte gjorts några försök hos oss. Vi vill visa med ljud och bild för intresserade åhörare hur vi har byggt detta arbete och hur hinder kan överbryggas. References Ramsden, Paul (2003). Learning to teach in higher education. 2. ed.

Genetic Transformation of Passionflower and Evaluation of R(1) and R(2) Generations for Resistance to Cowpea aphid borne mosaic virus

We report on the production and evaluation of passionflower transgenic lines for resistance to Cowpea aphid borne mosaic virus (CABMV). Genetic transformation was done using Agrobacterium tumefaciens and transgene integration was confirmed by Southern blot analyses, resulting in nine transgenic lines for `IAC 275` and three for `IAC 277`. Transgenic lines were clonally propagated and evaluated for resistance to CABMV After the third inoculation, under higher inoculum pressure, only propagated plants of the transgenic line T16 remained asymptomatic, indicating a high resistance to infection with CABMV. This transgenic line was self-pollinated and the RI generation was evaluated together with the RI generation of another resistant transgenic line (T2) identified previously. Plants were inoculated with CABMV by means of viruliferous Myzus nicotianae. All 524 T2R(1) plants became infected, whereas 13 of 279 T16R(1) remained asymptomatic after four successive inoculations. A TI6R(2) generation was obtained and plants were inoculated with CABMV mechanically or by aphids. After successive inoculations, 118 of 258 plants were symptomless, suggesting that the resistance to CABMV was maintained in the plant genome as the homozygous condition was achieved. Five selected resistant TI6R(2) plants which contained the capsid protein gene are being crossed for further analyses.

EVALUATION OF THE INFLUENCE OF THE PROTEINIC QUALITY OF THE GENETICALLY MODIFIED AND ORGANIC SOY BEANS IN THE GROWTH OF TWO GENERATIONS OF RATS WISTAR

[Evaluation of the influence of the proteinic quality of the genetically modified and organic soy beans in the growth of two generations of rats Wistar.] Avaliacao da influencia da qualidade proteica da soja geneticamente modificada e organica no crescimento de duas geracoes de ratos Wistar. Revista Brasileira de Medicina Veterinaria, 31(3):139-144, 2009. Programa de Pos-Graduacao em Patologia, Hospital Universitario Antonio Pedro. Centro de Ciencias Medicas, Universidade Federal Fluminense. Rua Marques do Parana, 303, Niteroi, RJ 24030-210, Brasil. E-mail: sergian@ufnj.br Sixty four Wistar rats, male of two consecutive generations determined as F(0) and F(1) were used to study the cumulative effect of two variety soy beans, cultivated with organic seasoning and genetically modified, The animals of each generation were divided into three groups of eight rats each fed on diets consisted of organic soy, soy genetically modified and casein respectively. All the animals received water and the diet ad libitum for period of 28 days. Where the diet consumption and the animals weight were evaluated. After statistic analysis of the results no expressive differences were observed on diet consumption, weight variation, protein efficient ratio and food efficiency ratio on same group of animals in the different generations. On the other hand, significant difference was found on final proteinic retention on animal descendants of the same groups; however of different generations. With this, the supplementation of organic soy with L-cistin provided better avail of this protein in relation to the protein of the soy genetically modified. However, this supplementation did not reveal efficiency in keeping the proteinic employment from one generation to another one, since soy varieties presented better performance on F(0) generation when compared with F(1).

Geographical variation in offspring size effects across generations

Offspring size is thought to strongly affect offspring fitness and many studies have shown strong offspring size/fitness relationships in marine and terrestrial organisms. This relationship is strongly mitigated by local environmental conditions and the optimal offspring size that mothers should produce will vary among different environments. It is assumed that offspring size will consistently affect the same traits among populations but this assumption has not been tested. Here I use a common garden experiment to examine the effects of offspring size on subsequent performance for the marine bryozoan Bugula neritina using larvae from two very different populations. The local conditions at one population (Williamstown) favour early reproduction whereas the other population (Pt. Wilson) favours early growth. Despite being placed in the same habitat, the effects of parental larval size were extremely variable and crossed generations. For larvae from Williamstown, parental larval size positively affected initial colony growth and larval size in the next generation. For larvae from the other population, parental larval size positively affected colony fecundity and negatively affected larval size in the next generation. Traditionally, exogenous factors have been viewed as the sole source of variation in offspring size/fitness relationship but these results show that endogenous factors (maternal source population) can also cause variation in this crucial relationship. It appears offspring size effects can be highly variable among populations and organisms can adapt to local conditions without changing the size of their offspring.

A rapid PCR protocol for marker assisted detection of heterozygotes in segregating generations involving 1BL/1RS translocation and normal wheat lines

A rapid and reliable polymerase chain reaction (PCR)-based protocol was developed for detecting zygosity of the 1BL/1RS translocation in hexaploid wheat. The protocol involved a multiplex PCR with 2 pairs of oligonucleotide primers, rye-specific Ris-1 primers, and consensus 5S intergenic spacer (IGS) primers, and digestion of the PCR products with the restriction enzyme, MseI. A small piece of alkali-treated intact leaf tissue is used as a template for the PCR, thereby eliminating the necessity for DNA extraction. The test is simple, highly sensitive, and rapid compared with the other detection systems of 1BS1RS heterozygotes in hexaploid wheat. PCR results were confirmed with AFLP analyses. Diagnostic tests for 1BL/1RS translocation based on Sec-1-specific ELISA, screening for chromosome arm 1RS controlled rust resistance locus Yr9, and the PCR test differed in their ability to detect heterozygotes. The PCR test and rust test detected more heterozygotes than the ELISA test. The PCR test is being used to facilitate S1 family recurrent selection in the Germplasm Enhancement Program of the Australian Northern Wheat Improvement Program. A combination of the PCR zygosity test with other markers currently being implemented in the breeding program makes this test economical for 1BL/1RS characterisation of S1 families.

Five generations of peace operations: from the "thin blue line" to "painting a country blue"

This article combines both international practice and analytical contributions into a systematic and synthetic presentation of the evolution of peace operations from their modern inception in 1948 to the present. It seeks to serve a didactic purpose in proposing a basic structure for Brazilian scholars' burgeoning debate on peace operations and intervention, rather than a definitive characterization of blue helmet practice. Peace operations' progression is traced through five analytical "generations," each adding a crucial factor distinguishing it from its predecessors. Each generation is placed in relation to changes in the nature of conflict and in the interpretation of the foundational principles of peace operations, and links to broader theoretical issues in International Relations are made explicit at each stage.

Phenotypic correlations and path analysis for plant architecture traits and grain production in three generations of cowpea

ABSTRACT The objective of this study was to analyze the phenotypic correlation and path analysis of traits related to plant architecture, earliness and grain yield in F2, BC1 and BC2 generations, from crosses between cowpea cultivars BRS Carijó and BR14 Mulato. Most phenotypic correlations of the examined traits were concordant in statistical significance, with approximate values ​​among the examined generations. For the trait seed weight, significant and positive phenotypic correlations were observed in the three generations only for the trait number of secondary branches. The values ​​of the direct effects were in agreement with the values ​​of the phenotypic correlations, which indicate true association by the phenotypic correlation among the traits of grain yield examined. Path analysis indicated that the selection of productive plants will result in early plants and an increased number of secondary branches. In F2, plants with shorter length of the main branch and shorter length of secondary branches can be obtained. The causal model explained 15 to 30% of the total variation in grain weight in relation to the traits examined. The analyses indicated the possibility of selecting plants with a higher and early grain yield, shorter length of primary branches and lower number of nodes, which are important variables for mechanical or semi-mechanical harvesting.

Caffeine effect on mortality and oviposition in successive generations of Aedes aegypti

OBJECTIVE: Previous experiments showed that caffeine blocks the development of Aedes aegypti (Diptera, Culicidae) in the larval stage, consequently inhibiting the production of adults. This study aimed at obtaining data suggestive of caffeine resistance by these mosquitoes. METHODS: Experiments were carried out in successive generations to assess adult production from eggs laid in previous generation and oviposition rate in every generation using 200 and 500 µg/mL caffeine. Tap water was used as control. Experiments were conducted in the city of São José do Rio Preto, Southeastern Brazil between 2002 and 2005. Statistical tests consisted of exploratory data analysis and smoothing algorithms. RESULTS: Increasing reduction in productivity of adults occurred among generations at both caffeine concentrations but the differences were only significant at 200µg/mL caffeine. As for the oviposition rate, there was a decrease in the mean number of eggs per female over generations at both caffeine concentrations. CONCLUSIONS: There was no evidence of caffeine resistance over generations. The study results corroborate caffeine as an alternative as an important Ae. Aegypti control agent to avoid resistance.
