A Review of: Herrera, G. (2015). Testing the patron-driven model: Availability analysis of first-time use books. Collection Management, 40(1), 3-16. doi: http://dx.doi.org/10.1080/01462679.2014.965863 Abstract Objective – To determine whether a hypothetical Patron-Driven Acquisition (PDA) purchasing model is acceptable in terms of making available print monographs after their initial publication. Design – Quantitative data analysis. Setting – A large public university located in the southern United States of America. Subjects – 8,020 item records representing books used at the author’s institution for the first time in 2012. Non-circulating monographs and items such as personal copy reserve materials and government documents were excluded from the sample. Methods – Using the libraries’ ILS, a listing of the titles of monographs that received first-time use in 2012 was generated and exported to Microsoft Excel. The Getting It System Toolkit (GIST) was used to batch-search possibilities for acquisition and/or access, including purchase (including Amazon and Better World Books) and free access (such as HaithiTrust and Google Books). Main Results – A total of 76% (6,130) of titles from the sample of 8,020 were available for purchase. A total of 3% (165) of these titles were both available for purchase and freely available online. Books not available either freely or by purchase represented 21% (1,682) of the sample. When participation in a regional resource-sharing consortium was accounted for, only 1% (101) of the titles could not be obtained. Books published before the 1920s were more likely to be freely available due to being in the public domain; however a majority of the titles (64%; 5,127) had a publication date of 1990 forward. The humanities represented the largest disciplinary grouping at 57% (4,563), with Social Sciences (31%; 2,472) and STEM (11%; 879) following. Conclusions – In sum, the results indicated a very low margin of unavailability for titles. The author notes that, based on the findings, there should be no PDA purchase restrictions according to publication date if a large-scale program were to be implemented at their institution, and that researchers requiring humanities titles would be likely to benefit most from such a program (p. 14). It should be noted that a significant budget for PDA was allocated at the author’s institution.

In allusion to the need of analyzing complex system, we have proposed a method named multi-grade color Petri net. We for the first time use this new method to analyze a missile training simulator system. This model can accurately reflect the complex environments of the system and avoid the difficulty occurring often in developing accurate mathematics model by using classical research approach.

Abstract Background After transfemoral amputation, many hours of practice are needed to re-learn walking with a prosthesis. The long adaptation process that consolidates a novel gait pattern seems to depend on cerebellar function for reinforcement of specific gait modifications, but the precise, step-by-step gait modifications (e.g., foot placement) most likely rely on top-down commands from the brainstem and cerebral cortex. The aim of this study was to identify, in able-bodied individuals, the specific modulations of cortical rhythms that accompany short-term gait modifications during first-time use of a dummy prosthesis. Methods Fourteen naïve participants walked on a treadmill without (one block, 4 min) and with a dummy prosthesis (three blocks, 3 × 4 min), while ground reaction forces and 32-channel EEG were recorded. Gait cycle duration, stance phase duration, step width, maximal ground reaction force and, ground reaction force trace over time were measured to identify gait modifications. Independent component analysis of EEG data isolated brain-related activity from distinct anatomical sources. The source-level data were segmented into gait cycles and analyzed in the time–frequency domain to reveal relative enhancement or suppression of intrinsic cortical oscillations. Differences between walking conditions were evaluated with one-way ANOVA and post-hoc testing (α = 0.05). Results Immediate modifications occurred in the gait parameters when participants were introduced to the dummy prosthesis. Except for gait cycle duration, these modifications remained throughout the duration of the experimental session. Power modulations of the theta, mu, beta, and gamma rhythms, of sources presumably from the fronto-central and the parietal cortices, were found across the experimental session. Significant power modulations of the theta, beta, and gamma rhythms within the gait cycle were predominately found around the heel strike of both feet and the swing phase of the right (prosthetic) leg. Conclusions The modulations of cortical activity could be related to whole-body coordination, including the swing phase and placing of the prosthesis, and the bodyweight transfer between legs and arms. Reduced power modulation of the gamma rhythm within the experimental session may indicate initial motor memories being formed. Better understanding of the sensorimotor processes behind gait modifications may inform the development of neurofeedback strategies to assist gait rehabilitation.

Interfaces between Mo substrate and free-standing diamond films prepared by DC arc plasma jet operated at gas recycling mode were investigated, including for the first time used and multi-time used substrate. The morphology, phase composition and bonding state of elements in the interface between substrates and diamond films were examined by optical microscopy, XRD and XPS. The profiles of carbon concentration of Mo substrates were measured by GDOES. It showed that Mo2C and MoC were formed on the first time used Mo substrate, and MoC was found on diamond films nucleation side after detachment. It suggested that MoC was peeled off from Mo substrate. The stable Mo2C on Mo substrate was formed after multi-time use of Mo substrate. However, MoC has not been found on it. The thickness of carburizing layer on the first time used Mo substrate is up to 30µm, and the carburizing layer on the multi-time used substrate is much thicker than that on the first used. The amorphous carbon in the surface of the substrate and nucleation side of diamond films was found by XPS, including for the first time used and multi-time used substrate.

This paper proposes a new goal-oriented (GO) method for reliability analysis of repairable systems with multiple-input and multi-function component (MIMFC). First, a new GO operator combination, which is composed of a new function GO operator and a new auxiliary GO operator, is created to represent MIMFC. The new function GO operator named as Type 22 operator is created to represent MIMFC itself, and the auxiliary GO operator named as Type 15B operator is created to represent multi-condition control signals of MIMFC. Then, GO operation formulas of the new GO operator combination are deduced based on logical relationships among inputs, outputs, and the component itself. The reliability analysis process of the new GO method is formulated. Furthermore, this new GO method is applied for the first time in steady availability analysis and qualitative analysis of the fan drive system of a power-shift steering transmission. Finally, the results obtained by the new GO method are compared with the results of fault tree analysis (FTA) and Monte Carlo simulation (MCS), and the comparison results show that this new GO method is reasonable and advantageous in reliability analysis of repairable systems with MIMFC. Moreover, the analysis process shows that it is more advantageous in the aspect of building system models and conducting reliability analysis. Overall, this paper not only improves the basic theory of the GO method and expands the application of the GO method, but it also provides a new approach for reliability analysis of repairable systems with MIMFC.

AbstractAmber teething necklaces supposedly provide analgesia for teething infants. Their use is becoming more widespread, despite lack of peer-reviewed evidence and warnings from Health Canada that they pose a strangulation and aspiration risk. To date, there have been no published reports of strangulation secondary to amber teething necklaces. In this report we present a case of non-fatal infant strangulation from the first time use of an amber teething necklace. We will also discuss the role of physicians as advocates in reporting similar cases and educating families. Finally, we will comment on the responsibility of all professionals and professional organizations that work with infants and toddlers to advocate for children by raising concerns and counselling parents.
