Authors: Khedr Abdalla M. , Abu Shawish Hazem M. , Gaber M. , Abed Almonem Khalid I. 
Published: June 2013

AbstractThis paper introduces the development a new chemically modified carbon paste electrode (CMCPE) for the determination of a cationic surfactant. The paste is based on alkyl dimethyl hydroxyethyl ammonium chloride (ADHACl) with phosphomolybdic acid as an ion‐exchanger (ADHA‐PM). The electrode exhibits a Nernstian slope of 59.1 ± 0.5 mV/decade for ADHA ions in the concentration range 1.0 × 10−6–1.0 × 10−3 M with the limit of detection of 8.2 × 10−7 M. The proposed electrode has a fast and stable response time of 5–8 s, a good reproducibility and it can be used in the pH range of 2.2–9.0. Selectivity coefficients, determined by a matched potential method and separate solution method, showed high selectivity for ADHA over a large number of inorganic cations and organic cations. These characteristics of the electrode enable it to be used successfully for determination of ADHA in shampoo and liquid detergents solutions by standard addition and the calibration curve methods. In addition, the modified electrode was applied as an indicator electrode in potentiometric titration and successfully used to determine ADHA in water samples with satisfactory results.
Does Parental Consent for Birth Control Affect Underage Pregnancy Rates? The Case of Texas
Authors: Girma Sourafel , Paton David 
Published: June 2013

AbstractPrevious work based on conjectural responses of minors predicted that the 2003 Texas requirement for parental consent for state-funded birth control to minors would lead to a large increase in underage pregnancies. We use state- and county-level data to test this prediction. The latter allow us to compare the impact of parental consent in counties with and without state-funded family planning clinics. We control for characteristics systematically correlated with the presence of state-funded clinics by combining difference-in-difference estimation with propensity score–weighted regressions. The evidence suggests that the parental consent mandate led to a large decrease in attendance at family planning clinics among teens but did not lead to an increase in underage pregnancies.
ON SUMMABILITY CONDITIONS FOR INTERVAL MAPS
Authors: LI HUAIBIN 
Published: June 2013

AbstractConsider a map of class ${C}^{3} $ with nonflat critical points and with all periodic points hyperbolic repelling. We show that the ‘backward contracting condition’ implies the summability condition. This result is the converse of Theorem 3 of Bruin et al. [‘Large derivatives, backward contraction and invariant densities for interval maps’, Invent. Math. 172 (2008), 509–533].

Authors: Prasai A , Nix P A , Aye M , Atkin S , England R J 
Published: June 2013

AbstractBackground:The role of total thyroidectomy in the management of patients with Graves' disease remains controversial. However, there is increasing evidence to support the role of the procedure as a safe and definitive treatment for Graves' disease.Method:Patients were identified from a prospective thyroid database of the multidisciplinary thyroid clinic at Hull Royal Infirmary. All case notes were independently reviewed to confirm the data held on the database.Results:Over a 7-year period, the senior author has performed 206 total thyroidectomies for Graves' disease. The incidence of temporary recurrent laryngeal nerve palsy and hypoparathyroidism was 3.4 per cent and 24 per cent respectively. There was one case of permanent unilateral recurrent laryngeal nerve palsy, and 3.9 per cent of patients developed permanent hypoparathyroidism. There has been no relapse of thyrotoxicosis.Conclusion:In the context of a multidisciplinary thyroid clinic, total thyroidectomy should be offered as a safe and effective first-line treatment option for Graves' disease.

Published: June 2013

AbstractSurface energy fluxes of the ice sheet close to oases (ice-free land regions) are crucial in the case of retreating ice sheet and growing oasis areas. This study presents a four-year record of the meteorological parameters, radiative and turbulent energy fluxes at the edge of the Antarctic ice sheet, close to Schirmacher Oasis in Dronning Maud Land, East Antarctica from March 2007–February 2011. The energy fluxes were analysed for summer season, winter season and transition periods. High katabatic winds were observed during winter (seasonal mean 9.3 m s-1) as compared to other seasons. A high correlation (r2= 0.89) was observed between the glacier surface temperature and air temperature, and regression relations were obtained for summer, winter and transition periods. The net radiative flux was the main heat source to the glacier during summer (46.8 W m-2) and heat sink during winter (-42.2 W m-2). Sensible heat flux (annual mean 32 W m-2) was the heat source and latent heat flux (annual mean -61 W m-2) was the heat sink to the glacier surface, averaged over all seasons. Comparison with other coastal or dry valley locations in Antarctica show that low humidity (50%), high katabatic winds (8.3 m s-1) and mild surface (-11.4°C) and air temperature (-10.2°C) contribute to high latent heat flux at the present study location.
What do we know about cognitive functioning in adult congenital heart disease?
Authors: Tyagi Manavi , Austin Katie , Stygall Jan , Deanfield John , Cullen Shay , Newman Stanton P. 
Published: June 2013

AbstractWith the advent of improved medical and surgical care in congenital heart disease, there has been an increase in the number of patients who survive into adulthood, giving rise to a new patient population ‘Adults with congenital heart disease’. In the past, morbidity and mortality were the primary concerns for this group. However, with improvements in outcome attention has shifted to other factors such as psychosocial and cognitive functioning. This paper reviews the literature on the cognitive functioning in adult congenital heart disease patients. A total of five relevant articles were retrieved via electronic searches of six databases, including MEDLINE, EMBASE, CINAHL, AMED, PsychINFO, and PubMed. The results displayed a consensus on the presence of some cognitive difficulties in adult congenital heart disease patients. The aetiology of cognitive dysfunctions appears to be multifactorial. The literature is limited by the very small number of studies looking at adults with congenital heart disease, with the majority focusing on cognitive functioning among children with congenital heart disease. However, the presence of cognitive dysfunctions and the resulting impact on the patient's day to day lives warrant for a more detailed and prospective research to enhance the understanding of its aetiology and impact.
Bridging the information literacy gap: library participation in summer transition programs
Authors: Barnhart Anne C. , Stanfield Andrea 
Published: June 2013

PurposeWith Complete College America and renewed interest in performance‐based funding models for higher education, colleges are focused on improving retention, progression and graduation rates. Many schools bring lower‐achieving students to campus for a pre‐first‐year program called Summer Bridge to give them an introduction to college. These summer programs have varying levels of library involvement. The authors aim to compare the level of library involvement at their institution with that of libraries where similar programs exist.Design/methodology/approachThe authors searched for schools with summer bridge programs, read through their program descriptions to find ones that were similar to their own situation (e.g. not STEM‐focused or Upward Bound), and sent a survey to 103 libraries. In total, 42 responded.FindingsOf the responding libraries 88 percent have face‐to‐face instruction with the summer bridge participants, however only 33 percent of the libraries did any assessment of this contact. Ten of the respondents teach credit‐bearing information literacy courses, but none offers this to the summer bridge students.Practical implicationsMany states require institutions to demonstrate student success in order to compete for limited state funds. Libraries have an important role to student success and librarians should strategically place themselves within that conversation. This article provides some possible means to help with summer bridge students.Originality/valueA search through library and education literature reveals that little has been written about library involvement with programs that are not Upward Bound affiliated. This case study and its survey respond to a gap in the literature of both fields.
Mind the gap: academic library outreach and EOP
Authors: Meyers‐Martin Coleen , Lampert Lynn D. 
Published: June 2013

PurposeThis article aims to describe the many ways academic library outreach practices are evolving through online formats. It underscores the implications of moving communications and resources online for educational opportunity program (EOP) students when considering these students' specific technology usage patterns and the need for face‐to‐face mentoring. The article seeks to make recommendations for libraries that intend to develop successful programming and interactions with transitional students online; and to bring to light the need for future research concerning the creation and usage of online educational support structures that specifically serve the EOP community.Design/methodology/approachA literature review discusses technology and academic library outreach programming as well as the historic and current digital divide and learning styles of EOP transitional students. Recommendations are made for how to best meet EOP student needs online to support the traditional in‐person programming in which these students succeed.FindingsIdentifying successful learning structures and potential technology usage patterns of EOP students provided the foundation for this article. Developing library outreach and programming within the online platforms EOP students access and utilize is necessary to support continued face‐to‐face interactions in an academic setting. More research is necessary in order to support transitional students in a digital format.Originality/valueThis article describes digital outreach efforts targeting non‐campus and campus communities, in particular within EOP transitional programming. It inquires about how to best meet transitional students in a digital format when they have historically succeeded in face‐to‐face educational interactions and settings.
Academic libraries, institutional missions, and new student recruitment: a case study
Authors: Gallup Kopp Maggie 
Published: June 2013

PurposeAcademic institutions struggle to differentiate themselves in the eyes of prospective students. Schools use their institutional missions to communicate their unique purposes and goals with core constituencies, but often the mission is not shared during recruitment. Academic libraries can assist in recruiting students by communicating the institution's mission through their collections. This paper aims to focus on the efforts of Brigham Young University's L. Tom Perry Special Collections.Design/methodology/approachThis case study examines the approach of Brigham Young University's L. Tom Perry Special Collections, which has worked with its campus admissions office by serving as a stop on campus tours for high‐priority academic and athletic recruits.FindingsThese tour sessions are more than just quick show‐and‐tell sessions; they are opportunities to discuss the university's unique “Aims of a BYU Education”.Originality/valueThe case study provides new perspectives on how academic libraries can demonstrate value by tying their services and collections to recruitment efforts and to the mission of their parent institutions.
Faculty‐librarian collaboration in improving information literacy of educational opportunity program students
Authors: Lei Hsieh Ma , McManimon Susan , Yang Sharon 
Published: June 2013

PurposeThis study aims to examine the instruction of basic information literacy (IL) skills taught to the socio‐economically disadvantaged students in the Educational Opportunity Program (EOP) at Rider University in summer 2011. The study set out to determine how the beginning IL levels of EOP freshmen differ from those of other freshmen, their learning outcomes, and retention of IL as a means to improve future research instruction.Design/methodology/approachFaculty of a speech communication class and two librarians collaborated in integrating IL in the class assignments of the 2011 summer EOP program. The assessment tools include identical pre‐ and post‐tests, a second post‐test with different multiple correct answer questions, a survey about students' perceptions of their IL training, and the teaching faculty's observations of EOP students' research skills.FindingsEOP freshmen are equivalent to the peer freshmen in their low levels of IL skills. The findings suggested that EOP freshmen complete IL instruction with stronger IL skills. The second post‐test revealed that many students were confused about some basic IL concepts. Faculty's observation of students' information literacy skills concurs with the pre‐ and post‐tests.Originality/valueThis study fills a void in the literature on recent research of information literacy skills of socio‐economically disadvantaged college students. The multi‐correct answer questions employed are valuable but rarely employed in studies or discussed in the literature. The collaboration of faculty and librarians in assignment design is valuable as an increasing number of faculty are utilizing librarians to teach the necessary IL skills needed in today's curricula.
Anisotropic hierarchic finite elements for the simulation of piezoelectric smart structures
Authors: Duczek Sascha , Gabbert Ulrich 
Published: June 2013

PurposePiezoelectric actuators and sensors are an invaluable part of lightweight designs for several reasons. They can either be used in noise cancellation devices as thin‐walled structures are prone to acoustic emissions, or in shape control approaches to suppress unwanted vibrations. Also in Lamb wave based health monitoring systems piezoelectric patches are applied to excite and to receive ultrasonic waves. The purpose of this paper is to develop a higher order finite element with piezoelectric capabilities in order to simulate smart structures efficiently.Design/methodology/approachIn the paper the development of a new fully three‐dimensional piezoelectric hexahedral finite element based on the p‐version of the finite element method (FEM) is presented. Hierarchic Legendre polynomials in combination with an anisotropic ansatz space are utilized to derive an electro‐mechanically coupled element. This results in a reduced numerical effort. The suitability of the proposed element is demonstrated using various static and dynamic test examples.FindingsIn the current contribution it is shown that higher order coupled‐field finite elements hold several advantages for smart structure applications. All numerical examples have been found to agree well with previously published results. Furthermore, it is demonstrated that accurate results can be obtained with far fewer degrees of freedom compared to conventional low order finite element approaches. Thus, the proposed finite element can lead to a significant reduction in the overall numerical costs.Originality/valueTo the best of the author's knowledge, no piezoelectric finite element based on the hierarchical‐finite‐element‐method has yet been published in the literature. Thus, the proposed finite element is a step towards a holistic numerical treatment of structural health monitoring (SHM) related problems using p‐version finite elements.
Industrial citizenship: a re‐conceptualisation and case study of the UK
Authors: Bagguley Paul 
Published: June 2013

PurposeThe purpose of this paper is to critically examine and reformulate T.H. Marshall's concept of industrial citizenship, and apply the reformulated model to a case study of the UK.Design/methodology/approachMarshall's conceptualisation of industrial citizenship is criticised for neglecting the rights of unions as collective rights and for treating industrial citizenship as an aggregation of individual rights. Subsequent attempts to use the idea of industrial citizenship are similarly flawed. A case study of changes to industrial citizenship in the UK in the 1980s and 1990s is used to develop the new model and provide evidence in support of it.FindingsAn alternative conceptualisation of industrial citizenship is presented that outlines collective and individual powers, obligations, liberties, constraints, immunities and liabilities. This model is illustrated using examples from the Conservative governments' industrial relations legislation of the 1980s and 1990s.Originality/valueDiscussions and applications of T.H. Marshall's concept of industrial citizenship are few and far between. The paper proposes an original re‐conceptualisation specifying the collective rights of unions in the British regime of industrial citizenship. This new concept of industrial citizenship is then applied to the radical changes in industrial relations legislation in the UK in the 1980s and 1990s.
Policing class and race in urban America
Authors: Fisher Andrew R.M. , Oddsson Guðmundur , Wada Takeshi 
Published: June 2013

PurposeThe purpose of this paper is to integrate conflict theory's class and race perspectives to explain police force size in large cities in the USA.Design/methodology/approachData on US cities with populations of 250,000 or greater (n=64) are used to test whether class and/or racial factors impact police force size. The data are analyzed using OLS regression.FindingsThis study finds that class and race factors combine to impact police force size concurrently. By adjusting the model specifications of a recent article, which concludes police force size in large US cities is determined by racial factors and not class, this study shows that two class‐related factors – racial economic inequality and poverty – significantly influence police force size. Additionally, this analysis calls into question the importance of racial factors; specifically, the threat caused by minority presence and a city's history of racially coded violence.Originality/valueFew conflict theorists have attempted to integrate class and race in order to explain police force size. The results of this study show that racial economic inequality interacts with poverty (class threat) and that they jointly affect police force size. This adds further nuance to the argument of the complex causal interaction of intersectionality and supports theoretical, methodological, and public policy shifts that blend class inequality and racial threat to explain police force size.

PurposeThis paper aims to describe and promote the interlibrary loan and document delivery services between North American and Japanese academic libraries. An overview of the overseeing bodies, the North American Coordinating Council on Japanese Library Resources and the Interlibrary Loan/Document Delivery Committee, is also described.Design/methodology/approachA descriptive approach is taken to explain the library‐focused programs supported by the North American Coordinating Council on Japanese Library Resources.FindingsAccess to Japanese language resources is increasingly higher in demand. The National Coordinating Council on Japanese Library Resources has fully supported libraries by providing interlibrary loan/document services between Japan and North America.Originality/valueThis paper provides step‐by‐step instructions for interlibrary loan practitioners whose libraries participate in the Global ILL Framework (GIF) program.
Free choice of learning management systems
Authors: Porter Gavin W. 
Published: June 2013

PurposeAlthough multiple studies examine institutional transitions of learning management systems (LMS) or compare their merits, studies examining students' free choice of access on parallel LMSs for the same course are absent from the literature. In order to investigate usage in a free‐choice situation, identical content was posted at the same time to two different LMSs in a large enrollment class with a diversity of majors.Design/methodology/approachTwo prevalent LMSs were utilized in the study: WebCT, which was in existence at a university‐wide level previously, and Moodle, which will become the new university‐wide system in the 2012‐13 academic year onwards. Both student self‐reports and LMS log usage data were analyzed. LMS preferences and usage groups were categorized.FindingsAlthough this inquiry revealed that most students chose to use the WebCT system (85 per cent WebCT users, 15 per cent Moodle users; both self‐reported and log‐verified), the reasons given for WebCT preference pertained largely to habit and that most other courses are using the WebCT LMS. In contrast, the reasons given for using Moodle spoke directly to the attributes of the LMS itself, namely the interface quality and the way it is organized.Originality/valueThis study indicates that institutions should look beyond student usage patterns in making LMS choices, and that LMS quality is sometimes, and perhaps unfortunately, overshadowed by student habit and familiarity.
