Assessing the Format of the Presentation of Text in Developing a Reading Strategy Assessment Tool (R-SAT)
We are constructing a new computerized test of reading comprehension called the Reading Strategy Assessment Tool (R-SAT). R-SAT elicits and analyzes verbal protocols that readers generate in response to questions as they read texts. We examined whether the amount of information available to the reader when reading and answering questions influenced the extent to which R-SAT accounts for comprehension. We found that R-SAT was most predictive of comprehension when the readers did not have access to the text as they answered questions
Understanding how grammatical aspect influences legal judgment
Recent evidence suggests that grammatical aspect can bias how individuals perceive criminal intentionality during discourse comprehension. Given that criminal intentionality is a common criterion for legal definitions (e.g., first-degree murder), the present study explored whether grammatical aspect may also impact legal judgments. In a series of four experiments participants were provided with a legal definition and a description of a crime in which the grammatical aspect of provocation and murder events were manipulated. Participants were asked to make a decision (first- vs. second-degree murder) and then indicate factors that impacted their decision. Findings suggest that legal judgments can be affected by grammatical aspect but the most robust effects were limited to temporal dynamics (i.e., imperfective aspect results in more murder actions than perfective aspect), which may in turn influence other representational systems (i.e., number of murder actions positively predicts perceived intentionality). In addition, findings demonstrate that the influence of grammatical aspect on situation model construction and evaluation is dependent upon the larger linguistic and semantic context. Together, the results suggest grammatical aspect has indirect influences on legal judgments to the extent that variability in aspect changes the features of the situation model that align with criteria for making legal judgments
Using Latent Semantic Analysis to Assess Reader Strategies
We tested a computer-based procedure for assessing reader strategies that was based on verbal protocols that utilized latent semantic analysis (LSA). Students were given self-explanation-reading training (SERT), which teaches strategies that facilitate self-explanation during reading, such as elaboration based on world knowledge and bridging between text sentences. During a computerized version of SERT practice, students read texts and typed self-explanations into a computer after each sentence. The use of SERT strategies during this practice was assessed by determining the extent to which students used the information in the current sentence versus the prior text or world knowledge in their self-explanations. This assessment was made on the basis of human judgments and LSA. Both human judgments and LSA were remarkably similar and indicated that students who were not complying with SERT tended to paraphrase the text sentences, whereas students who were compliant with SERT tended to explain the sentences in terms of what they knew about the world and of information provided in the prior text context. The similarity between human judgments and LSA indicates that LSA will be useful in accounting for reading strategies in a Web-based version of SERT
Changing How Students Process and Comprehend Texts with Computer-based Self-Explanation Training
This study assessed whether and how self-explanation reading training, provided by iSTART (Interactive Strategy Training for Active Reading and Thinking), improves the effectiveness of comprehension processes. iSTART teaches students how to self-explain and which strategies will most effectively aid comprehension from moment-to-moment. We used RSAT (Reading Strategy Assessment Tool) to assess how iSTART changes the relation between important selfexplanation reading strategies—bridging and elaboration—and online comprehension, and how often they are produced. College and high school students received iSTART and were administered RSAT prior to and post-training. Results from three experiments showed that iSTART primarily benefits bridging inferences when self explaining. The frequency of bridging inferences was higher post training than prior to training, but only in the experiments involving college students. Additionally, prior to exposure to iSTART, RSAT bridging scores did not predict comprehension performance, whereas they did after iSTART, suggesting that iSTART may improve comprehension processes by teaching students how to appropriately use selfexplanation to address comprehension difficulties. Finally, the results from this study suggest that RSAT may provide a valuable computer-based assessment of the effectiveness of selfexplanations that could be used in conjunction with iSTART and in future research on selfexplanation

Assessing the use of multiple sources in student essays
Abstract The present study explored different approaches for automatically scoring student essays that were written on the basis of multiple texts. Specifically, these approaches were developed to classify whether or not important elements of the texts were present in the essays. The first was a simple pattern-matching approach called "multi-word" that allowed for flexible matching of words and phrases in the sentences. The second technique was latent semantic analysis (LSA), which was used to compare student sentences to original source sentences using its high-dimensional vectorbased representation. Finally, the third was a machinelearning technique, support vector machines, which learned a classification scheme from the corpus. The results of the study suggested that the LSA-based system was superior for detecting the presence of explicit content from the texts, but the multi-word pattern-matching approach was better for detecting inferences outside or across texts. These results suggest that the best approach for analyzing essays of this nature should draw upon multiple natural language processing approaches
Relationships between task awareness, comprehension strategies, and literacy outcomes
Reading is typically guided by a task or goal (e.g., studying for a test, writing a paper). A reader’s task awareness arises from their mental representation of the task and plays an important role in guiding reading processes, ultimately influencing comprehension outcomes and task success. As such, a better understanding of how task awareness arises and how it affects comprehension is needed. The present study tested the Task Awareness Mediation Hypothesis. This hypothesis assumes that the strategies that support reading comprehension (e.g., paraphrasing, bridging, and elaborative strategies) also support a reader’s task awareness while engaged in a literacy task. Further, it assumes that the reader’s level of task awareness partially mediates the relationship between these comprehension strategies and a comprehension outcome. At two different time points in a semester, college students completed an assessment of their propensity to engage in comprehension strategies and a complex academic literacy task that provided a measure of comprehension outcomes and an assessment of task awareness. Indirect effects analyses provided evidence for the Task Awareness Mediation Hypothesis showing that the propensity to engage in paraphrasing and elaboration was positively predictive of task awareness, and that task awareness mediated the relationships between these comprehension strategies and performance on the complex academic literacy task. These results indicate that task awareness has complex relationships with comprehension strategies and performance on academic literacy tasks and warrants further consideration as a possible malleable factor to improve student success
Die Auswirkungen der Russifizierung auf die deutschbaltische Gesellschaft am Beispiel von Johannes Haller und seiner Mitgliedschaft in der Korporation Estonia
Die vorliegende Bakkalaureusarbeit beschäftigt sich verallgemeinernd mit der
Russifizierung in den privilegierten deutschen Ostseeprovinzen 1883–1900. Dabei
konzentriert man sich auf den Einfluss dieser neuen Politikrichtung des russischen
Imperiums in der Universitätsstadt Dorpat in derselben Zeitspanne. Dorpat war als
eine baltische Stadt bis dann quasi als eine andere Welt war mit ihren eigenen
Rechten. Die dörptschen deutschbaltischen Verbindungen vertraten zugleich im
Laufe des 19. Jahrhunderts die Sitten und Würden der dominanten Oberschicht,
weshalb man sich auf sie und ihre Reaktion auf die Russifizierung besonders
intensiv konzentriert. Dabei entsteht die Verknüpfung zu diesem
Modernisierungsverfahren und dem berühmten deutschbaltischen Historiker
Johannes Haller (1865–1947) und seinen Erfahrungen. Mit seiner akademischen
Arbeit hat er das Geschichtsbewusstsein über die Deutschbalten in Deutschland
verbessert. Dabei war er in Jahren 1883–1888 Student in Dorpat und Mitglied der
deutschbaltischen Korporation Estonia. Welchen Einfluss hatte in diesem Fall die
Russifizierung auf Hallers Leben und seine Verbindung Estonia, die man als
typische Vertreter des deutschbaltischen Wesens gegen Ende des 19. Jahrhunderts
bezeichnen kann?http://www.ester.ee/record=b4688441*es
Effect of Age on Variability in the Production of Text-Based Global Inferences
As we age, our differences in cognitive skills become more visible, an effect especially true for memory and problem solving skills (i.e., fluid intelligence). However, by contrast with fluid intelligence, few studies have examined variability in measures that rely on one’s world knowledge (i.e., crystallized intelligence). The current study investigated whether age increased the variability in text based global inference generation–a measure of crystallized intelligence. Global inference generation requires the integration of textual information and world knowledge and can be expressed as a gist or lesson. Variability in generating two global inferences for a single text was examined in young-old (62 to 69 years), middle-old (70 to 76 years) and old-old (77 to 94 years) adults. The older two groups showed greater variability, with the middle elderly group being most variable. These findings suggest that variability may be a characteristic of both fluid and crystallized intelligence in aging
Contributions of mean and shape of blood pressure distribution to worldwide trends and variations in raised blood pressure: A pooled analysis of 1018 population-based measurement studies with 88.6 million participants
© The Author(s) 2018. Background: Change in the prevalence of raised blood pressure could be due to both shifts in the entire distribution of blood pressure (representing the combined effects of public health interventions and secular trends) and changes in its high-blood-pressure tail (representing successful clinical interventions to control blood pressure in the hypertensive population). Our aim was to quantify the contributions of these two phenomena to the worldwide trends in the prevalence of raised blood pressure. Methods: We pooled 1018 population-based studies with blood pressure measurements on 88.6 million participants from 1985 to 2016. We first calculated mean systolic blood pressure (SBP), mean diastolic blood pressure (DBP) and prevalence of raised blood pressure by sex and 10-year age group from 20-29 years to 70-79 years in each study, taking into account complex survey design and survey sample weights, where relevant. We used a linear mixed effect model to quantify the association between (probittransformed) prevalence of raised blood pressure and age-group- and sex-specific mean blood pressure. We calculated the contributions of change in mean SBP and DBP, and of change in the prevalence-mean association, to the change in prevalence of raised blood pressure. Results: In 2005-16, at the same level of population mean SBP and DBP, men and women in South Asia and in Central Asia, the Middle East and North Africa would have the highest prevalence of raised blood pressure, and men and women in the highincome Asia Pacific and high-income Western regions would have the lowest. In most region-sex-age groups where the prevalence of raised blood pressure declined, one half or more of the decline was due to the decline in mean blood pressure. Where prevalence of raised blood pressure has increased, the change was entirely driven by increasing mean blood pressure, offset partly by the change in the prevalence-mean association. Conclusions: Change in mean blood pressure is the main driver of the worldwide change in the prevalence of raised blood pressure, but change in the high-blood-pressure tail of the distribution has also contributed to the change in prevalence, especially in older age groups
