Partial Quasi-Bilateral Generating Function Involving some Special Functions

A group-theoretic method of obtaining more general class of generating functions from a given class of partial quasi-bilateral generating functions involving Hermite, Laguerre and Gegenbaur polynomials are discussed.

Bilateral visual outcomes and service utilization of patients treated for 3 years with ranibizumab for neovascular age-related macular degeneration

Background: The aim of this study was to describe bilateral visual outcomes and the effect of incomplete follow-up after 3 years of ranibizumab therapy for neovascular age-related macular degeneration. Secondarily, the demands on service provision over a 3-year period were described. Methods: Data on visual acuity, hospital visits, and injections were collected over 36 months on consecutive patients commencing treatment over a 9-month period. Visual outcome was determined for 1) all patients, using last observation carried forward for missed visits due to early discontinuation and 2) only those patients completing full 36-month follow-up. Results: Over 3 years, 120 patients cumulatively attended hospital for 1,823 noninjection visits and 1,365 injection visits. A visual acuity loss of <15 letters (L) was experienced by 78.2% of patients. For all patients (n=120), there was a mean loss of 1.68 L using last observation carried forward for missing values. Excluding five patients who died and 30 who discontinued follow-up, mean gain was 1.47 L. In bilateral cases, final acuity was on average 9 L better in second eyes compared to first eyes. Also, 91% of better-seeing eyes continued to be the better-seeing eye. Conclusion: We have demonstrated our approach to describing the long-term service provision and visual outcomes of ranibizumab therapy for neovascular age-related macular degeneration in a consecutive cohort of patients. Although there was a heavy burden with very frequent injections and clinic visits, patients can expect a good level of visual stability and a very high chance of maintaining their better-seeing eye for up to 3 years. © 2014 Chavan et al.

Visual and quality outcomes following bilateral implantation of a trifocal intraocular lens

Purpose: To examine visual outcomes following bilateral implantation of the FineVision trifocal intraocular lens (IOL; PhysIOL, Liège, Belgium). Methods: 26 patients undergoing routine cataract surgery were implanted bilaterally with the FineVision Trifocal IOL and followed up post-operatively for 3 months. The FineVision optic features a combination of 2 diffractive structures, resulting in distance, intermediate (+1.75 D add) and near vision (+3.50 D add) zones. Apodization of the optic surface increases far vision dominance with pupil aperture. Data collected at the 3 month visit included uncorrected and corrected distance (CDVA) and near vision; subjective refraction; defocus curve testing (photopic and mesopic); contrast sensitivity (CSV-1000); halometry glare testing and a questionnaire (NAVQ) to gauge near vision function and patient satisfaction. Results: The cohort comprised 15 males and 11 females, aged 52.5–82.4 years (mean 70.6 ± 8.2 years). Mean post-operative UDVA was 0.22 ± 0.14 logMAR, with a mean spherical equivalent refraction of +0.02 ± 0.35 D. Mean CDVA was 0.13 ± 0.10 logMAR monocularly, and 0.09 ± 0.07 logMAR binocularly. Defocus curve testing showed an extensive range of clear vision in both photopic and mesopic conditions. Patients showed high levels of satisfaction with their near vision (mean ± 0.9 ± 0.6, where 0 = completely satisfied, and 4 = completely unsatisfied) and demonstrated good spectacle independence. Conclusion: The FineVision IOL can be considered in patients seeking spectacle dependence following cataract surgery, and provide good patient satisfaction with uncorrected vision.

Does the balanced scorecard make a difference to the strategy development process

A great number of strategy tools are being taught in strategic management modules. These tools are available to managers for use in facilitating strategic decision making and enhancing the strategy development process in their organisations. A number of studies have been published examining which are the most popular tools; however there is little empirical evidence on how their utilisation influences the strategy process. This paper is based on a large scale international survey on the strategy development process, and seeks to examine the impact of a particular strategy tool, the Balanced Scorecard (BSC), upon the strategy process. Recently, it has been suggested that as a strategy tool, the BSC can influence all elements of the strategy process. The results of this study indicate that although there are significant differences in some elements of the strategy process between the organisations that have implemented the BSC and those that have not, the impact is not comprehensive. © 2011 Operational Research Society Ltd.

A case of bilateral perisylvian syndrome with reading disability

Bilateral Perisylvian Syndrome (BPS) often presents with epilepsy and significant behavioral impairments that can include mental retardation, dysarthria, delayed speech development, and delayed fine motor development (Graff-Radford et al., 1986 and Kuzniecky et al., 1993). While a small subset of BPS cases have been described as having relatively isolated language delays (Leventer et al., 2010), BPS is not expected in children with dyslexia. As part of a Medical University of South Carolina, IRB approved multi-site study involving retrospective and de-identified dyslexia data, we unexpectedly identified a 14.05 year old male with evidence of BPS whose father had been diagnosed with dyslexia and dysgraphia. This child had been recruited for a neuroimaging study on dyslexia from a school specializing in educating children with dyslexia. The T1-weighted MRI scan from this child demonstrated a highly unusual perisylvian sulcal/gyral patterning that is a defining feature of BPS (Fig. 1). BPS cases exhibit bilateral dysgenesis of the Sylvian fissure and surrounding gyri, which appears to occur because of a limited or absent arcuate fasciculus (Kilinc, Ekinci, Demirkol, & Agan, 2015). This BPS case also had a relatively enlarged atrium of the lateral ventricle that is consistent with the BPS anatomical presentation and reduction of parietal white matter (Graff-Radford et al., 1986, Kilinc et al., 2015 and Toldo et al., 2011).

Üzleti teljesítménymérés a sportban, - avagy miként segítheti a sportszervezetek vezetőit a Balanced Scorecard koncepció a stratégia szerinti működésben = Measuring Business Performance in Sports - How the Balanced Scorecard approach can help sports organisations in operating along strategic objectives

Napjainkban egyre nagyobb figyelem fordul a sporttevékenység társadalmi hasznosságára, ugyanakkor számos sportszervezet a túléléséért küzd. A legtöbb sportszervezetnél a sportteljesítmény mérése dominál, s viszonylag kevés figyelmet fordítanak az üzleti teljesítmény és az ezt befolyásoló tényezők mérésére, annak ellenére, hogy a vezetők tudatában vannak a sportteljesítmény és az üzleti teljesítmény kölcsönös összefüggésével. A sportteljesítményt a fogyasztói elégedettségen keresztül bevételre kell váltani, illetve biztosítani kell a finanszírozási forrásokat (gondolhatunk akár a játékosok fizetésére) a megfelelő sportteljesítmény eléréséhez. A sportszervezetek vezetőinek át kell látniuk a sportteljesítmény és az üzleti teljesítmény összefüggéseit, és azonosítaniuk kell a kritikus értékteremtő tényezőket. Ehhez adhat egy megfelelő gondolkodási keretet a Balanced Scorecard alkalmazása. Tanulmányunkban egy rövid áttekintést adunk a Balanced Scorecard alkalmazásának előnyeiről és kihívásairól a non-profit szervezetek esetében, majd egy magyarországi kézilabda klubnál készített esettanulmány segítségével megvizsgáljuk a BSC alkalmazási lehetőségét a sportkluboknál. _____ While performance measurement in the sport industry has a traditionally strong focus on sports results, commercial success of sports clubs needs to gain more ground. Sports results should generate market revenues, by satisfying customer needs, and allow continued investment in the further improvement of sports success (i.e. more funds for player transfers and wages). Club managers need to understand the complex relationship between on-field and off-the-field success, and identify critical success factors for achieving strategic objectives. The Balanced Scorecard approach provides a plausible framework for such analysis. Our paper explains the challenges of and opportunities for implementing a Balanced Scorecard system in non-profit organisations, and provides insights into its application in professional sport through an in-depth case study of a handball club in Hungary. We conclude by providing a model for managing sports organisations in line with strategic objectives, balancing out stakeholder expectations for both sports results and commercial success.

Analysis of Housing Partnerships using the Balanced Scorecard framework

Housing Partnerships (HPs) are collaborative arrangements that assist communities in the delivery of affordable housing by combining the strengths of the public and private sectors. They emerged in several states, counties, and cities in the eighties as innovative solutions to the challenges in affordable housing resulting from changing dynamics of delivery and production. ^ My study examines HPs with particular emphasis upon the identification of those factors associated with the successful performance of their mission of affordable housing. I will use the Balanced Scorecard (BSC) framework in this study. The identification of performance factors facilitates a better understanding of how HPs can be successful in achieving their mission. The identification of performance factors is significant in the context of the current economic environment because HPs can be viewed as innovative institutional mechanisms in the provision of affordable housing. ^ The present study uses a mixed methods research approach, drawing on data from the IRS Form 990 tax returns, a survey of the chief executives of HPs, and other secondary sources. The data analysis is framed according to the four perspectives of BSC: the financial, customer, internal business, and learning and growth. Financially, revenue diversification affects the financial health of HPs and overall performance. Although HPs depend on private and government funding, they also depend on service fees to carry out their mission. From a customer perspective, the HPs mainly serve low and moderate income households, although some serve specific groups such as seniors, homeless, veterans, and victims of domestic violence. From an internal business perspective, HPs’ programs are oriented toward affordable housing needs, undertaking not only traditional activities such as construction, loan provision, etc., but also advocacy and educational programs. From an employee and learning growth perspective, the HPs are small in staff size, but undertake a range of activities with the help of volunteers. Every part of the HP is developed to maximize resources, knowledge, and skills in order to assist communities in the delivery of affordable housing and related needs. Overall, housing partnerships have played a key role in affordable housing despite the housing market downturn since 2006. Their expenses on affordable housing activities increased despite the decrease in their revenues.^

Projeto de intervenção adaptando o Balanced Scorecard ao sistema de compras da Base Aérea de Natal

The present proposal for intervention examines the issue of public procurements carried out by a military organization on a Federal Public Administration. The main objective of this paper is to propose a model of strategic planning based on the Balanced Scorecard for the public procurement system, which contributes to increased efficiency, efficacy and effectiveness of acquisitions made in the Air Base of Natal city. Therefore, Structured interviews were used in order to make a diagnosis of the current reality of the procurement system along with the main requirement sectors of BANT, as well as the adaptation of the prospects of the BSC based on literature review. The technique used for the analysis of the interviews was the analysis of content whose results contributed to the preparation of the conceptual Strategic Map which was submitted to validation through a Focal Group. It was concluded through the analysis of the interviews, that the system of purchases of BANT is in a tactical profile because of low interaction between the system of purchases and the requirement sectors, aiming only at the “economicity” of acquisition in opposition of the effectiveness of material acquired, the lack of training of the elements which build the system and the absence of a proper planning. It is intended with thecreation of this proposal to contribute to the improvement of management with a focus on results in public administration as well as increasing efficiency, efficacy and effectiveness of public procurements. Whereas for the particular case the measurement of the results can only be performed after at least a year of its implementation, the present research constitutes a proposal of intervention.

Equitably coloured balanced incomplete block designs

In this thesis we determine necessary and sufficient conditions for the existence of an equitably ℓ-colourable balanced incomplete block design for any positive integer ℓ > 2. In particular, we present a method for constructing non-trivial equitably ℓ-colourable BIBDs and prove that these designs are the only non-trivial equitably ℓ-colourable BIBDs that exist. We also observe that every equitable ℓ-colouring of a BIBD yields both an equalised ℓ-colouring and a proper 2-colouring of the same BIBD. We also discuss generalisations of these concepts including open questions for further research. The main results presented in this thesis also appear in [7].
