Survey of Web Developers in Academic Libraries

A survey was sent to library Web designers from randomly selected institutions to determine the background, tools, and methods used by those designers. Results, grouped by Carnegie classification type, indicated that larger schools were not necessarily working with more resources or more advanced levels of technology than other institutions.     

It may not be that difficult the second time around: the effects of rereading on the comprehension and metacomprehension of negated text

The present research explored the awareness that readers have of the difficulty of negative text and aimed to determine whether rereading could impact comprehension and metacomprehension. Participants read passages that sometimes contained negative words such as ‘no’ and ‘not’, rated their comprehension, and answered a comprehension question about the passage. Half of the passages were read twice and rated again before the participant was prompted to answer a comprehension question. Results showed that passages that were read twice were rated as easier to understand, and questions that corresponded with those passages were answered with higher accuracy as well. However, these improvements were not exclusive to negated passages. And, while participants were aware that the negative passages were harder to comprehend, this understanding did not aid in heightened comprehension of the negative text. Rereading was demonstrated to be a helpful strategy overall but was not sufficient to specifically help with negation.     

Identification of beneficial mass-included inerter-based vibration suppression configurations

Vibration suppression capabilities of linear passive vibration absorbers, such as traditional tuned mass damper (TMD), and recently proposed inerter-based vibration absorbers, have been studied for multiple mechanical systems. In particular, significant performance advantages have been obtained with a specific device making use of both inerter and mass elements, namely the tuned mass damper inerter (TMDI). However, there are still countless mass-included inerter-based configurations that have not been studied, which can potentially provide more preferred dynamic properties. In this paper, an immittance-function-layout (IFL) is introduced, which can cover a large range of topological connection possibilities with both mass and inerter elements. With the recently proposed structural immittance format, a systematic approach is established to identify the most beneficial IFL type mass-included inerter-based configurations with pre-determined number of each element type. Vibration suppression performance with single-IFL type device and two parallel-connected IFLs (i.e. dual-IFL) type devices are investigated in this paper. Three optimal configurations are identified for mitigating the maximum inter-storey drift of an example 3-storey building model subjected to base excitation. With this 3-storey building model, results show that, for the optimum single-IFL configuration, the performance improvement is 7.3% compared with the optimum TMDI, and with identified beneficial dual-IFL configurations, up to 34.9% performance advantages are obtained. Furthermore, consistent performance gains are shown under real-life earthquake inputs and with a 10-storey building model using identified absorber configurations.     

Teaching Play Skills to Children with Disabilities: Research-Based Interventions and Practices

Play is a critical milestone that contributes to the learning and development of young children in multiple ways and is essential to their well-being. Play is also considered as a central component to promote school readiness and incorporates pre-literacy, language and numeracy skills. However, play deficits seem to be acutely apparent in some children with disabilities. This highlights the need to come to terms with the best evidence and explore the promising practices related to improved play skills for young children with disabilities. The purpose of this paper is to provide an overview of play-based learning in early childhood and early childhood special education and provide research-based recommendations on teaching play skills to young children with disabilities.     

The role of social community and individual differences in minority mentoring programs

Researchers have examined various outcomes of undergraduate minority mentoring programs. However, there is a significant gap in research about how program members with different demographic backgrounds may not have the same experiences or outcomes as other members despite being subject to the same program elements. To address these gaps, we employed a social community framework to examine the differences across the perceptions of connectedness to a social community and participant outcomes of members of the University of Illinois at Urbana-Champaign (UIUC) Merit Program (MP) for Emerging Scholars. An ANOVA was performed for a study sample of n = 179 current and past MP participants. Results indicated a need to: (a) find ways to translate experiences to lower performing groups, (b) identify other approaches to build resilience and encourage connections and engagement in communities of practice, and (c) explicitly educate all participants in the importance of social community in their professional development.     

Differential Learning as a Key Training Approach to Improve Creative and Tactical Behavior in Soccer

Purpose: The aim of this study was to identify the effects of a differential-learning program, embedded in small-sided games, on the creative and tactical behavior of youth soccer players. Forty players from under-13 (U13) and under-15 (U15) were allocated into control and experimental groups and were tested using a randomized pretest to posttest design using small-sided games situations. Method: The experimental group participated in a 5-month differential-learning program embodied in small-sided games situations, while the control group participated in a typical small-sided games training program. In-game creativity was assessed through notational analyses of the creative components, and the players’ positional data were used to compute tactical-derived variables. Results: The findings suggested that differential learning facilitated the development of creative components, mainly concerning attempts (U13, small; U15, small), versatility (U13, moderate; U15, small), and originality (U13, unclear; U15, small) of players’ actions. Likewise, the differential-learning approach provided a decrease in fails during the game in both experimental groups (moderate). Moreover, differential learning seemed to favor regularity in pitch-positioning behavior for the distance between players’ dyads (U13, small; U15, small), the distance to the team target (U13, moderate; U15, small), and the distance to the opponent target (U13, moderate; U15, small). Conclusions: The differential-learning program stressed creative and positional behavior in both age groups with a distinct magnitude of effects, with the U13 players demonstrating higher improvements over the U15 players. Overall, these findings confirmed that the technical variability promoted by differential learning nurtures regularity of positioning behavior.     

Beneficial Effect of Aqueous Garlic Extract on Inflammation and Oxidative Stress Status in the Kidneys of Type 1 Diabetic Rats

One of the most important complications of diabetes is nephropathy. This study investigates the effects of aqueous garlic extract on inflammation and oxidative stress status in the kidneys of diabetic rats. Male rats were divided into four groups- control rats, diabetic rats, garlic extract-treated diabetic rats, garlic extract-treated normal rats. The glucose, urea, uric acid, and creatinine levels were measured in sera using colorimetric methods. To determine the oxidative stress condition in the kidney tissues, total antioxidant capacity (TAC), malondialdehyde (MDA), and total oxidant status (TOS) were measured using colorimetric methods. Inflammation status was evaluated by the determination of tumor necrosis factor-alpha (TNF-α) gene and protein expression using qRT-PCR and ELISA respectively, while nitric oxide (NO) level in these tissues was measured using the Griess method. Histological examination of Kidneys was carried out by H&E staining. The levels of glucose, urea, and uric acid were found to increase in the serum of diabetic rats and decrease in that of diabetic rats after treatment with garlic. Measurement of MDA, TOS, and TAC revealed oxidative stress in diabetic rats, which improved after receiving the extract. The NO and TNF-α protein levels in diabetic rats were higher than those in control rats. After treatment with garlic, the levels of TNF-α protein and NO became close to the normal levels. Histological results confirmed certain other data as well. Garlic has antioxidant properties; therefore, it can reduce oxidative stress, which plays an important role in the development of diabetic nephropathy. Reduction in oxidative stress has beneficial effects on inflammation because it leads to a decrease in the level of TNF-α.     

Great Expectations: Museums and Regional Economic Development in England

This polemic addresses the political expectations of museums in England. Its starting point is the premise of the Department for Culture, Media and Sport that museums make a significant contribution to regional economies, if not to the national economy. Political expediency requires museums to provide evidence for their economic worth. But it could be argued that estimates of museums' economic impact are devalued by being blatantly constructed for the purposes of advocacy. This paper explores various issues that inform the practice of associating museums with economic development. It considers whether the government's cultural policies and aspirations have served to misrepresent (if not exaggerate) the economic impact that museums currently exert, or are deemed capable of exerting. It closes by suggesting that there are some ambiguities in the commitment of the DCMS to the premise that museums are economically important, and by examining implications for the future.
