A Review of: Curry, A. (2005). If I ask, will they answer? Evaluating public library reference service to gay and lesbian youth. Reference & User Services Quarterly, 45(1), 65-75. Retrieved from https://www.jstor.org/journal/refuseserq Abstract Objective - To assess the quality of service provided by reference staff in public libraries when presented with a request for LGBTQ information by a young person. Design - Unobtrusive observation without informed consent. Setting - Public library branches in the greater Vancouver area, British Columbia, Canada. Subjects - Reference librarians. Methods - A 19-year-old posing as a high school student approached reference desk staff at 20 public library branches. The student proxy, “Angela”, was instructed to ask for books on forming a gay-straight alliance at her school and, if there was a full reference interview, to also ask for recommendations of novels that the group might read. She recorded the reactions, both verbal and nonverbal, using Reference and User Services Association guidelines as a template. Library administrators were aware of the potential visits and permitted the research, but the reference desk staff were not aware of a potential visit by the student proxy. The researcher claimed that her method, while deceptive, was necessary to obtain authentic reactions from the library staff. Main Results - Most reference librarians approached by Angela made adequate attempts to assist her, although a few library staff reacted negatively to her query. Half of the librarians reacted positively to the patron’s request, with most of the others providing neutral responses. Very few of the librarians actually taught the patron how to use the library’s catalog to search for materials, and most of the librarians were unable to find appropriate materials due to not knowing the appropriate search terms. Only three library staff showed overt disapproval of the search topic, such as frowning or rushing to finish the reference interview quickly, with most remaining objective or supportive. Because of the service she received, Angela stated that eight of the 20 libraries were welcoming enough that she thought she would return. Conclusion - The wide range of responses received by Angela indicated that there was room for improvement in educating public library staff on gay and lesbian issues and materials, especially for gay and lesbian youth.

Voice over Internet Protocol (VoIP) is a telecommunications technology that is able to pass the communication service in Internet Protocol networks so as to allow communicating between users in an IP network. However VoIP technology still has weakness in the Quality of Service (QoS). VOPI weaknesses is affected by the selection of the physical servers used. In this research, VoIP is configured on Linux operating system with Asterisk as VoIP application server and integrated on a Raspberry Pi by using wired and wireless network as the transmission medium. Because of depletion of IPv4 capacity that can be used on the network, it needs to be applied to VoIP system using the IPv6 network protocol with supports devices. The test results by using a wired transmission medium that has obtained are the average delay is 117.851 ms, jitter is 5.796 ms, packet loss is 0.38%, throughput is 962.861 kbps, 8.33% of CPU usage and 59.33% of memory usage. The analysis shows that the wired transmission media is better than the wireless transmission media and wireless-wired.

External Dacryocystorhinostomy

Abstract Objective External dacryocystorhinostomy is thought to cause mucociliary dysfunction by damaging the mucosa, in turn affecting ciliary activity and mucus quality. This study investigated the effect of external dacryocystorhinostomy on sinonasal function. Methods Patients scheduled for unilateral external dacryocystorhinostomy who underwent endoscopic nasal examination and paranasal sinus computed tomography were included in this study. A saccharine test was performed on the planned surgical side and the mucociliary clearance time was determined. The sinonasal quality of life was measured in all patients, pre-operatively and at six months post-operatively, using the Sino-Nasal Outcome Test-22. The Lund–Kennedy endoscopic score was also determined in all patients, both pre- and post-operatively. Results The study comprised 28 patients (22 females and 6 males). A statistically significant difference was found between the pre- and post-operative saccharine test results (p = 0.006), but not between the pre- and post-operative Sino-Nasal Outcome Test-22 scores (p > 0.05). Conclusion This study is one of only a few to investigate the effect of external dacryocystorhinostomy on sinonasal function. The results showed that external dacryocystorhinostomy impairs mucociliary clearance. The surgical procedure is well tolerated and does not significantly change nasal symptom scores.

Friction between the tow and tool surface normally happens during the tow production, fabric weaving, and application process and has an important influence on the quality of the woven fabric. Based on this fact, this paper studied the influence of tension and relative velocity on the three kinds of untwisted-glass-fiber tow-on-roller friction with a Capstan-based test setup. Furthermore, an improved nonlinear friction model taking both tension and velocity into account was proposed. According to statistical test results, firstly, the friction coefficient was found to be positively correlated with tension and relative velocity. Secondly, tension and velocity were complementary on the tow-on-roller friction behavior, with neither being superior to the other. Thirdly, an improved model was found to present well the nonlinear characteristics between friction coefficient and tension and velocity, and predicational results of the model were found to agree well with the observations from Capstan tests.

Libraries do not receive much stress in correction textbooks, and librarians are not ordinarily scheduled as speakers at correctional conferences or published in correctional journals. For these reasons and because good library services are not generally available in state prison libraries across the nation, administrators may not be aware of the advantages a good library and librarian can offer. A survey of the fifty state institutional library consultants concerning adult correctional institution libraries resulted in forty-two replies representing 223 major libraries and 202 camp libraries. As of the winter of 1970, librarians holding masters' degrees or bachelors' degrees plus school certification served full- or part-time in fifty-eight libraries in twenty-nine states. There were 955,154 volumes in the libraries in the reporting states; however, many of the books were described as old, outdated, or unsuitable. To meet minimum standards, there should have been 1,422,580 books of quality. The lack of qualified librarians together with inadequate budgets has resulted in uncatalogued, unclassified collections, insufficient discarding, poor staff libraries, a shortage of related staff services, and a lack of reference service, reading guidance, book discussions, writers' groups, and other library-sponsored activities. Information was also gathered on public library assistance to institutions, bookmobiles, inmate access to shelves, and separate rooms for reading, listening, and viewing.

Evidence Based Guideline

Abstract Background: Although the methodological quality of therapeutic guidelines (GLs) has been criticized, little is known regarding the quality of GLs that make diagnostic recommendations. Therefore, we assessed the methodological quality of GLs providing diagnostic recommendations for managing diabetes mellitus (DM) and explored several reasons for differences in quality across these GLs. Methods: After systematic searches of published and electronic resources dated between 1999 and 2007, 26 DM GLs, published in English, were selected and scored for methodological quality using the AGREE Instrument. Subgroup analyses were performed based on the source, scope, length, origin, and date and type of publication of GLs. Using a checklist, we collected laboratory-specific items within GLs thought to be important for interpretation of test results. Results: The 26 diagnostic GLs had significant shortcomings in methodological quality according to the AGREE criteria. GLs from agencies that had clear procedures for GL development, were longer than 50 pages, or were published in electronic databases were of higher quality. Diagnostic GLs contained more preanalytical or analytical information than combined (i.e., diagnostic and therapeutic) recommendations, but the overall quality was not significantly different. The quality of GLs did not show much improvement over the time period investigated. Conclusions: The methodological shortcomings of diagnostic GLs in DM raise questions regarding the validity of recommendations in these documents that may affect their implementation in practice. Our results suggest the need for standardization of GL terminology and for higher-quality, systematically developed recommendations based on explicit guideline development and reporting standards in laboratory medicine.

AbstractUndoped GaN epilayers were grown on c-plane sapphire substrates under different growth temperatures by metalorganic chemical vapour deposition (MOCVD). The optical and structural characteristics of these grown samples were studied and compared. It was found that the crystalline quality of GaN film deposited at 1050°C was better that of other samples. Photoluminescence spectra showed that the intensities of yellow luminescence band of the samples decreased as the growth temperature increased. All above test results demonstrate that high temperature deposition can serve as a good method for high-quality GaN epilayer growth and there exists an optimal growth temperature.

Abstract A method to scale and deform a trimmed NURBS surface while holding the shape and size of specific features (trimming curves) unchanged is presented. The new surface is formed by scaling the given surface according to the scaling requirement first; and then attaching the (original) features to the scaled NURBS surface at appropriate locations. The attaching process requires several geometric operations and constrained free-form surface deformation. The resulting surface has the same features as the original surface and same boundary curves as the scaled surface while reflecting the shape and curvature distribution of the scaled surface. This is achieved by minimizing a shape-preserving objective function which covers all the factors in the deformation process such as bending, stretching and spring effects. The resulting surface maintains a NURBS representation and, hence, is compatible with most of the current data-exchange standards. Test results on several car parts with trimming curves are included. The, quality of the resulting surfaces is examined using the highlight line model.
