Engagement of Academic Libraries and Information Science Schools in Creating Curriculum for Sustainability: An Exploratory Study

In 2010, the Association for the Advancement of Sustainability in Higher Education released, “Sustainability curriculum in higher education: A call to action,” encouraging infusion of sustainability topics into universities' teaching and research. Since then, academic programs and research related to social, economic, and environmental sustainability have enriched university curricula. An exploratory study was conducted to determine the position and engagements of academic libraries and information science schools in their contributions to scholarly sustainability activities and curricular initiatives. This article presents the results of the study which reveals a number of engagements by library professionals in the areas of sustainability, such as increasing open access to research, building sustainability-related collections and research guides, and incorporating sustainability content into information literacy. While academic libraries and information science schools are engaged in a broad spectrum of initiatives that support their institutions' sustainability research and curricular functions, this study indicates that such activities require a more targeted approach.     

The Impact of Gender,Accommodations, and Disability on the Academic Performance of Canadian University Students with LD and/or ADHD

Academic accommodations for students experiencing disabilities are increasingly available at postsecondary institutions. More studies of the efficacy of accommodations for student success are warranted, however. Given the increased gender gap in university participation, more focus on the unique impact of gender is also needed. Using a sample of students registered with Access and Inclusion Services with learning disabilities (LD), attention-deficit/hyperactivity disorder (ADHD), and combined LD/ADHD at a Canadian undergraduate university (N = 661), we explored the impact of gender on academic performance and accommodation usage. Next, we examined how gender intersected with the impact of academic accommodations on academic performance. Women, on average, demonstrated better academic performance. Academic strategies and assistive technologies were not associated with higher academic performance. However, testing accommodations (extended time and environmental accommodations) were positively associated with academic performance for men with LD or ADHD, but not for the combined group LD/ADHD. For the former two, the more tests accommodated, the higher the academic performance. Furthermore, this gender association was most prominent for students experiencing ADHD. Interpretations and policy recommendations related to these findings are presented.     

Three-dimensional fit-to-flow microfluidic assembly

Three-dimensional microfluidics holds great promise for large-scale integration of versatile, digitalized, and multitasking fluidic manipulations for biological and clinical applications. Successful translation of microfluidic toolsets to these purposes faces persistent technical challenges, such as reliable system-level packaging, device assembly and alignment, and world-to-chip interface. In this paper, we extended our previously established fit-to-flow (F2F) world-to-chip interconnection scheme to a complete system-level assembly strategy that addresses the three-dimensional microfluidic integration on demand. The modular F2F assembly consists of an interfacial chip, pluggable alignment modules, and multiple monolithic layers of microfluidic channels, through which convoluted three-dimensional microfluidic networks can be easily assembled and readily sealed with the capability of reconfigurable fluid flow. The monolithic laser-micromachining process simplifies and standardizes the fabrication of single-layer pluggable polymeric modules, which can be mass-produced as the renowned Lego^® building blocks. In addition, interlocking features are implemented between the plug-and-play microfluidic chips and the complementary alignment modules through the F2F assembly, resulting in facile and secure alignment with average misalignment of 45 μm. Importantly, the 3D multilayer microfluidic assembly has a comparable sealing performance as the conventional single-layer devices, providing an average leakage pressure of 38.47 kPa. The modular reconfigurability of the system-level reversible packaging concept has been demonstrated by re-routing microfluidic flows through interchangeable modular microchannel layers.     

Do examinations influence student evaluations?

This paper measures the impact of timing on student evaluations of teaching effectiveness, using a dataset of close to 3000 observations from Erasmus School of Economics. A special feature of the data is that students were able to complete on-line questionnaires during a time window ranging from one week before to one week after the final examination. This allows for the isolation of the effect of the examination on student evaluations. Among students who subsequently pass the exam, we find little difference between pre- and post-exam ratings. Among students who fail, evaluation scores are significantly lower after the exam on a number of items. Our evidence is compatible with a self-serving bias in student evaluations, but does not indicate that students seek revenge on instructors through lower ratings.     

Maternal representations of the infant: associations with infant response to the still face

Mothers' representations of their infants may influence early development of emotional self-regulation. This study examined the associations between characteristics of mothers' (N = 100) narratives about their 7-month-old infants, maternal depression, and their infants' affect regulation during the Still Face procedure. Findings showed that (1) mothers' representations were linked with individual differences in their infants' behavior across the Still Face procedure, (2) the association between mothers' representations and their infants' behavior was mediated by parenting behavior, and (3) mothers' representations explained unique variance in their infants' affect regulation beyond the contribution of maternal depression. Although infants' displays of positive affect diminished while mothers held a still face, only infants of mothers in the balanced representation category returned to high levels of positive affect upon resuming interaction. These findings highlight the role of maternal representations in the process by which dyads repair temporary disruptions in interaction, as well as individual differences in infants' and mothers' responses to the Still Face.     

Order and duration of stimuli are important determinants of reactivation

Prior cuing treatments intended to alleviate the forgetting of a conditioned avexsion-to an odor were tested with 18-day-old rats. Previous experiments had shown that when such pups were conditioned with the use of a CS?/CS+ procedure, pretest presentation of the CS? or US, but not the CS+, alleviated the forgetting otherwise seen after a 3-h retention interval. In Experiment 1, it was determined that the forgetting was not alleviated if the GS? was either preceded or followed by presentation of the CS+, despite the fact that the CS?/CS+ ordering mimicked that of original conditioning. Experiment 2 was an examination of the balance of extinction and reactivation effects caused by presenting the CS+ for varying durations following the 3-h retention interval. The forgetting over this interval was alleviated if the CS+ was presented for 5 or 15 sec, but not 30 sec. With an increase in duration of exposure from 15 to 30 sec, the consequences of the CS+ as a prior cuing treatment apparently shifted from reactivation to extinction. Experiment 3 was a test of the interaction between the consequences of different lengths of CS+ exposure and the effectiveness of adding CS? to the CS+ as a reactivation treatment. The varied effectiveness of reactivation treatments is discussed interms of a change in stimulus conditions from training to reactivation.     

Faculty roles and role preferences in ten fields of professional study

Teaching faculty in ten entry-level professional fields reported varying amounts of time devoted to teaching, research, consulting, and professional practice but did not differ in time devoted to administration. The faculty member's own role view was most closely related to time use, but for time spent in teaching and research, faculty age and institutional type (but not gender) were also significant predictors. Even after several general demographic characteristics and environmental variables that potentially differentiate professional from discipline-based faculty are taken into account, different professional fields may be characterized by group climates which influence or reinforce certain faculty roles.
