Impact of information use architecture on load and usability

Information use is defined as the application of acquired and transmitted information in the decision making of an organization at the strategic and tactical levels. The purpose of the research is to investigate how information use architecture impacts information load and usability at the operational level of manufacturing where machines, humans and the production processes are information users. A new approach to information load is introduced which takes all the characteristics of information use (tacit, mechanical, paper and digitized) and possibilities of users (machine, operator and process) into consideration. Information use nodes are conceptualized building blocks for information use architecture which impact information load and usability. The results suggest that information use load is sensitive to information encoding/decoding. A combination of the federated and integrated information use architectures tends to result in a low information use load and can become a strategic tool for waste reduction. How information usability relates to load varies depending on the usability characteristic in view. The major conclusion is that a holistic approach to information systems includes the consideration of information use architecture which is an important factor in the management of information load and usability at the operational level.     

Looking Far And Looking Near: Student Insights On History,Language, And Power

ABSTRACT

Three community college students participated in a collaborative student/professor research project to experiment with new ideas in teaching. Under the direction of the instructor, the students studied the South African riots in Soweto, 1976, and how issues of language and power were connected to this event. This investigative process began with video information to introduce students to the key issues, and was then followed by student research and discussion. The students, who were particularly motivated to understand the conflict by relating it to their own linguistic circumstances, worked individually and together to find articles and video sources to support their personal interests and ideas. By reflecting on their experiences and perceptions about language and communication, students were able to become engaged in an unfamiliar historical topic, discover relevant academic information, evaluate sources, and formulate insightful responses.     

Trajectories of Adjustment in a Brazilian Sample of Street-Involved Youth

Trajectories of adjustment were examined in a sample of street-involved youth across a 1-year period. Participants (N = 113; M_age = 14.18 years; 80.5% male, 91% non-White) were recruited in three Brazilian cities. Interviews conducted at three time points included six measures of physical and psychological adjustment. Unconditional growth models revealed linear declines over time (i.e., improved adjustment) on three indicators: health symptoms, sexual risk behaviors, and negative affect. There were no linear changes in drug use, positive affect, or life satisfaction. Conditional growth models revealed few significant effects for age or gender, but ratings of stressful life events moderated longitudinal changes in health symptoms, drug use, and negative affect. Implications for practice, policy, and theory are discussed.     

Discrimination of the number of sequential events by rats

Ten rats were trained to press a right lever following two successive sounds and to press a left lever following four successive sounds. Three sound sequences were used in initial discrimination training, such that reliable classification could not be based on the duration of each sound, the interval between sounds, or the total duration of the sound sequence. Classification of seven novel sound sequences suggested that the animals were either using number or the sum of sound durations in a sequence as the relevant cue. When this total sound duration was put in conflict with number, rats classified by number. The conclusion was that rats can discriminate number, even when temporal cues are controlled.     

A closer look at bilingual students’ use of multimodality in the context of an area comparison problem from a large-scale assessment

In this article, we use multimodality to examine how bilingual students interact with an area task from the National Assessment of Educational Progress in task-based interviews. Using vignettes, we demonstrate how some of these students manipulate the concrete materials, and use gestures, as a primary form of structuring their explanations and making mathematical meaning. We use our results as a basis to challenge the possible deficit perspective of bilingual students’ mathematical knowledge in current assessment practices. Choosing tasks that afford multiple modes of engagement and recognizing multimodal explanations in assessment practices has the potential to move us towards a better understanding of what bilingual students know and can do mathematically.     

Using multiple methods to investigate eleven-year-olds’ experiences of preparing for a high-stakes public examination in Trinidad and Tobago

This study was designed to uncover and evaluate unintended and indirect consequences of using the Secondary Entrance Assessment (SEA) in Trinidad and Tobago for high-stakes selection and placement. A major argument is that the test-taker is central to consequences, both intended and unintended. Data were obtained from eleven-year-olds preparing and taking the examination using multiple qualitative methods, which privilege agency and personal and social consciousness. Methods capturing the test-takers’ experience included diaries, focus groups, drawings, photovoice, and photo-elicitation. The findings were summarised by a theory of action and reported in integrated themes. Test preparation was mostly drill and practice. Both test preparation and test-taking were emotion-eliciting events requiring significant investment in positive social relationships to buffer negative impact. The costs and impact of early high-stakes examinations in Trinidad and Tobago might be higher than anticipated.
