This study investigated whether psychometric characteristics of mathematic alternate assessment items created for 2% students in grade 8 can be meaningfully estimated with data obtained from general education students in lower grades. Participants included 23 2% students in grade 8 and 235 general education students in grades 6-8. Twenty three 2% students were identified through the Student Performance Test (10 standard items and 10 2% items) and the Teacher Perception Survey. Performance on 10 2% items by the 2% students and the general education students were analyzed to address the questions: (a) are there grade levels at which the item parameters estimated from general education students in grade 6-8 are not different from those obtained using the 2% student sample? and (b) are there grade levels at which the estimated ability of general education students in grades 6-8 are not different the 2% student sample in grade 8? Results indicated that the item response patterns of 2% students in grade 8 were comparable to those of general education students in grades 6 and 7. Additionally, 2% students in grade 8 showed comparable mathematics performance on 2% items when compared to general education students in grades 6 and 7. Considering the content exposure of students in lower grades, this study concluded that data from general education students in grade 7 would be more appropriate to be used in designing alternate assessment for 2% students in grade 8 than data from students in grade 6. The general conclusion is that using data obtained from general education students in lower grade levels may be an appropriate and efficient method of designing alternate assessment items. / Advisers: Dr. Beth Ham, Co-Chair; Dr. Paul Yovanoff, Co-Chair

Statewide accountability programs are incorporating academic growth estimates for general assessments. This transition focuses attention on modeling growth for students with significant cognitive disabilities (SWSCD) who take alternate assessments based on alternate achievement standards (AA-AAS), as most states attempt to structure their AA-AAS systems as similarly as possible to their general assessments (GA). Test scaling, group heterogeneity, small sample sizes, missing data, and the use of status-based assessments that were not necessarily designed to measure a developmental continuum complicate modeling growth for SWSCD. This study addressed these challenges by: (a) analyzing test results from a common scale, (b) modeling achievement and growth for students in multiple demographic and exceptionality categories, and (c) using multiple cohorts to increase sample sizes. Latent growth curve modeling (LGCM) was used to define growth estimates based on exceptionality, sex, race, and economic disadvantage. Unconditional latent class growth analysis (LCGA) was used to determine the number of homogeneous subgroups that existed within the heterogeneous population of SWSCD for subsequent growth mixture modeling (GMM). Unconditional GMM was used to define the number of homogeneous subgroups of students with similar intercept and growth patterns within the overall population of SWSCD. Discriminant function analysis (DFA) including student exceptionality, sex, race, and economic disadvantage status was also used to analyze class membership post hoc. SWSCD with different exceptionalities generally had significantly different average initial achievement but growth rates that did not differ significantly from each other. SWSCD classified as economically disadvantaged performed significantly lower than their peers in initial achievement, yet exhibited growth rates that were not statistically different than the reference group. This study also found evidence for two separate latent classes of students with exceptionalities on the Oregon AA-AAS. The first class had lower achievement and larger growth rates, while the second class had higher achievement and slower growth rates. Students identified as SLD and CD were generally higher-performing, while students identified as ID, ASD, and OI were lower performing across all analytic models.

Master of Science / Department of Plant Pathology / Erick D. DeWolf / Wheat streak mosaic (WSM) is a devastating disease of winter wheat (Triticum aestivum L.) in Kansas. Although WSM can cause heavy crop losses, the severity of regional and statewide losses varies by year and location. Wheat streak mosaic is caused primarily by the Wheat streak mosaic virus (WSMV) and is spread by the wheat curl mite, Aceria tosichella Keifer. To infect fall planted wheat, both the virus and mite require a living, grass host to survive the summer months. The first research objective was to determine the risk of different grass species to serve as a source of WSM. Published experiments and surveys were reviewed to determine the suitability of each host based on a set of criteria. An analysis of the reports from the reviewed literature found 39 species to host both pests. Categorical analysis of these observations suggested that well-studied grass species could be placed in four risk groupings with ten species at high risk of carrying both pests. Furthermore, results from controlled experimentation generally agrees with results from field survey results for both pests. The second objective was to determine the weather and cropping factors that are associated with regional epidemics of WSM in Kansas. Historic disease observations, weather summaries, soil moisture indices, and cropping statistics were collected from Kansas crop reporting districts from 1995-2013. Binary response variables (non-epidemic case vs epidemic cases) were developed from different thresholds of district losses attributed to WSM. Variables associated with WSM epidemics were identified by a combination of non-parametric correlation, classification trees, and logistic regression. This analysis indicates that the total acres of wheat planted per season was associated with the low frequency of epidemics in Eastern Kansas. Temperature during September appears to influence the yield losses caused by WSM. Wheat planting generally begins during September and continues through October in the state. Temperature during the winter months (December-February) was also identified as important with warm conditions favoring outbreaks of disease. Dry soil conditions in February was also associated with epidemics of WSM. Models combining these variables correctly classified 60 to 74% of the cases considered in this analysis.

In the theoretical part, there I devote to the family itself, what are its functions, further I deal with a marriage and parenthood. In the next chapter I explain the divorce with minor children, causes of the divorce rate and the children´s reactions to the divorce. This is followed by a chapter on the social worker dealing with the children´s social and legal protection, his roles and competences, which dilemmas he encounters during his work. Last but not least I deal with the mutual and alternate care. What are prerequisites of the successful alternate care, its advantages and disadvantages. I chose a technique of a semi-structured interview for the qualitative research. There is a minimum of topics and questions that the interviewer must discuss. These basic topics and interviews then are attached by various other additional topics that the interviewer seemed to be meaningful or suitable to an extension of the original assignment. Data obtained through the interview I worked out using the coding. The research sample has been represented by the department of the children´s social and legal protection. This department belongs under the department of social affairs in municipalities with extended powers. Specifically, they were social workers of this department who I gained all the necessary information for the research from. The aim of this thesis was to describe the dilemmas of the social worker in the area of the social work in connection with the decision on the alternate care for the minor child. The research showed that there still prevails the number of children, who are placed by the court in the sole custody of mothers in the Czech Republic. It more often happens, that children´s fathers who were for the alternate care at the beginning, after a certain time revise their opinions and decide to leave the education of the children to their mothers. Regarding the dilemmas of the social workers dealing with the children´s social and legal protection, there are situations which occur more and more. These are especially situations when parents cannot agree on any rules on which the alternate care could run smoothly. In those above mentioned situations the child is placed in the sole custody to one of the parents. The everyday problem of the social workers is a large number of clients. The main reason for this is a growing number of divorces. To be able to cope with so many clients, all leads to the fact that the social workers are forced to reduce their time, energy, but also their attention which is to be paid to individual clients. Specifically in České Budějovice, the social workers from the department of the children´s social and legal protection lead only very few consultations with their clients directly in their office. It is especially due to the lack of their time, because they more often go to investigate a particular family on demand of the court. Many social workers meet the fact that the family wants to realize the alternate care, but for the reason of the non-cooperation of the both parents most of the alternate cares come to an end. As for the forms of the alternate care, most families realize a week alternate care. Mainly it is at the primary school-age children for the reason that the children are small and after a short time they miss the other parent. A 14-day alternate care is realized at the older children. They usually dislike their permanent moving from one parent to the other. A contribution of this thesis is to provide a topic for the social workers dealing with the children´s social and legal protection, to use it in their own practice in connection with the alternate care. Finally, the results can be used for an evaluation of the social workers´ approach to the families wishing to realize the alternate care.

Transmedialt berättande innebär berättande som sker över flera medium som samverkar för att berätta samma berättelse, där varje medium dessutom enskilt bör hålla god form, för att sedan skapa en större summa när det sammanförs med de andra. En sådan produktion kräver mycket ur publiken, såväl som forskare, då man behöver analysera och värdera varje enskild del av berättelsen varpå man kan ta sig an den fulla konstellationen. Denna uppsats syfte är att belysa transmedia och hur det kan brukas, samt undersöka hur webserien Marble Hornets utnyttjar sin transmedialitet för att forma flera berättare. Seriens berättarform kommer därefter jämföras med filmtolkningen av serien, Always Watching: A Marble Hornets Story, för att belysa vad transmedialiteten tillför för möjligheter, vilket sedan diskuteras. I studien utnyttjades en blandning av narrativa och semiotiska analysmetoder och tyder på att transmedia och alternate reality gaming öppnar många dörrar för manusskribenter för att förändra hur berättelsen skildras, på flera olika sätt.

Estas hipóteses foram testadas em plantas que sofreram ou não desbaste total de frutos com o intuito de induzir variações na demanda de assimilados. O experimento foi executado em Cordeirópolis (SP) em plantas de laranjeira "Valência? de 2,5 anos de idade, crescidas em vasos de 100 L. Em maio de 2009, a metade das plantas foi completamente desbastada de frutos. A partir de julho e ao longo do ciclo produtivo avaliaram-se a dinâmica de assimilação de CO2, carboidratos e compostos nitrogenados, e a atividade de enzimas da assimilação de nitrogênio. O experimento foi inteiramente casualizado com três ou quatro repetições, segundo o parâmetro avaliado, o tratamento estatístico dos dados foi como parcelas subdivididas no tempo. Em relação à primavera a fotossíntese é reduzida no inverno e no verão, como consequência da ocorrência de temperaturas mais baixas e mais altas, respectivamente. Porém, a condição fisiológica da planta também afeta a assimilação de CO2, a qual é incrementada pela alta demanda de carboidratos antes e durante a floração, mesmo sob baixa temperatura. A presença de frutos inibe parcialmente a brotação e floração visto que plantas desbastadas têm sete vezes mais flores; fixam 31% mais frutos e eles são 6% maiores. A floração é o processo de maior consumo de assimilados, e quanto mais intensa, maior o consumo de amido. Floração e frutificação são os únicos estádios nos quais se observaram diferenças entre os tratamentos; plantas com maior quantidade de flores têm maior consumo de assimilados. O amido continua a ser consumido até o fim da queda fisiológica dos frutos no verão, quando atinge o teor mínimo. Ramos e raízes maiores que 1 mm de diâmetro aportam amido durante o desenvolvimento das brotações e dos frutos. Entre o desbaste e a frutificação há aumento no teor de nitrogênio total nas folhas do último fluxo, ramos e raízes, ainda com baixa temperatura, resultado da maior demanda. O aumento no metabolismo induz maior síntese de proteína nas folhas e raízes menores que 1 mm de diâmetro. A enzima redutase do nitrato (RN) tem a menor atividade quando comparada com o sistema glutamina sintetase/glutamato sintase, sugerindo ser a que limita a taxa de assimilação de NO3-. Nas folhas a atividade in vitro da RN incrementa até a frutificação, e segue o padrão de variação sazonal observado na fotossíntese; nas raízes sua atividade é constante ao longo do ano / Abstract: The hypotheses of the study are that seasonal variations in environmental conditions affect the assimilation rate of resources while there is accumulation and remobilization of reserves in all the organs of plant to attend variations in nutrients demand. Each phenological stage has different needs, which would affect CO2 assimilation rate and metabolism of carbohydrates and nitrogen. To analyzer these hypotheses the objective was to evaluate the photosynthesis, flowering and fruit production, accumulation and remobilization of carbohydrates during of production cycle, in plants with and without fruit. Also it was objective to evaluate the annual dynamics of nitrogenous compounds and activity of enzymes of nitrogen assimilation. The study was conducted in Cordeirópolis (SP) in plants 'Valencia' orange of 2.5 years old, grown in pots of 100 L. In may 2009, at the start of the trial, half of plants was completely defruit, and starting from july and throughout the production cycle were evaluated photosynthesis, budding, flowering and fruit production, status of reserves of sugars, nitrogen compounds and enzymatic activities. The experimental design was completely randomized with three or four replications, with three or four repetitions, depending on the variable assessed, with split plots in time. It is observed that photosynthesis decreased in winter and summer, consequence of low and high temperature and radiation, respectively. However, the physiological condition of plant also affects the uptake, inducing an increase in photosynthesis prior to flowering, even at low temperatures. The largest demand of plants with fruits results in an increase on efficiency of energy use which comes of the assimilation and reserves. The presence of fruits partially inhibits the sprouting and blooming, even with high leaves starch content, defruited plants have seven times more flowers, fruit set is 31% higher and they are 6% greater. The flowering has the greater consumption of all phenological stages, when it is more intense, largest starch consumption. The flowering and fruiting are the only stages with differences between the treatments; plants with the more fruits and demand have more assimilates consumption. Starch is consumed until the end of june drop, in summer, when it reaches minimum content. Starch for development of flowers and fruits can be contributed by younger shoots, shoots older than one year and roots larger than 1 mm across. From the defruited plants until fruiting the total nitrogen content increases in mature leaves, shoots and roots, even at low temperatures, as result of the higher demand. Soluble protein is accumulated in mature leaves and roots smaller than 1 mm across as a result of increased metabolism. The nitrate reductase enzyme has the lowest activity when compared with the system glutamine synthetase/glutamate synthase, which would indicate that nitrate reductase activity controls the assimilation rate of NO3-. Nitrate reductase in vitro activity in leaves is increased until fruiting, and has seasonal variations similar like was observed in photosynthesis. Nitrate reductase in vitro activity in roots is constitutive throughout the year / Doutorado / Biologia Vegetal / Doutor em Biologia Vegetal

The rosy apple aphid, Dysaphis plantaginea, (Homoptera: Aphididae) is a serious pest of apples in British Columbia (BC), Canada and especially in organic orchards where conventional controls cannot be used. The goals of this study were to determine the environmental or management factors of an orchard that lead to high aphid populations, to conduct an economic assessment of the damage, to determine the timing of autumn migration, and to test several autumn and spring chemical control methods and two novel autumn mechanical control methods targeting the aphids while on their alternate host, Plantago major. To explain the variation among orchards, I evaluated several potential correlates of aphid density: abundance of the alternate host (plantain, Plantago major), foliar tree nitrogen, tree age, tree planting density, and the application of an oil treatment in spring. Stepwise regression indicated that foliar nitrogen and tree age explain 27% of the variation. Orchards receiving a spring oil application had a 53% lower average aphid infestation level. Plantain abundance was not related to aphid population on apple. However, experimental manipulation of leaf angle from the ground and size showed that significantly more alate and apterous aphids occurred on large, low angle leaves. Mowing prior to spring aphid migration was associated with 75% fewer alatae and apterae on the plantain. The loss in harvest resulting from aphid damage ranged from 3% to 76% of the crop. Effective autumn control depends on accurate timing of aphid flight. The peak of female flight occurred on the 27th of September, 2007 at 11:56 hours daylength (sunrise to sunset) and the peak of male flight occurred on the12th of October, 2007 at 11:02 hours daylength. Aphid densities in the spring of 2008 were very low, making comparisons between treatments and controls difficult. Autumn applications of Superior dormant oil and kaolin clay were not effective. The PureSpray Green treatments of two October applications and one April application showed a significant reduction in rosy apple aphid infested clusters compared with the untreated control. Mowing and rotavating did not result in a significant reduction in aphid infestation level. / Land and Food Systems, Faculty of / Graduate

What makes some marketing campaigns so immensely big and well known when they are marketed through social media or with a viral approach? How can a company reach out to customers through viral marketing and how can they make use of today’s social media to achieve it? In this article we will try to understand and further explore what a campaign have to accomplish in order to achieve a viral spread, using a descriptive model which uses a number of factors and terms necessary in order to properly analyze viral marketing campaigns. This model as it stands today is at its first steps towards being a tool for producers to incorporate in their analytic research and design process when creating viral campaigns.

‘Democracy’ has been frequently praised by the Chinese political leadership, while liberal democratic institutions have remained conspicuously absent under CPC one-party rule. This study explores the discourse on democracy in the newspaper China Daily between the years 2007 and 2017 to determine how the concept is articulated in a Chinese presumably alternate discourse on democracy. Fifty articles published between 2007 and 2017 are sampled, and a discourse analysis is performed to identify prominent themes featured in these articles concerning democracy. The sample is then further divided in two subsamples with a cutoff in 2012, to investigate whether there has been a qualitative shift in the discourse since the accession to power of Xi Jinping. The analysis shows that - and how – the discourse treats China largely as a particular democracy, frequently contrasted with ‘Western-style democracy’, and downplays certain democratic principles and institutions in favor of alternative ones. It also shows that an overall shift in tone seems to have occurred since the accession of Xi, from optimistic and progressive to a more negative one.
