Fixed point theorems for cyclic self-maps involving weaker Meir-Keeler functions in complete metric spaces and applications
No full textWe obtain fixed point theorems for cyclic self-maps on complete metric spaces
involving Meir-Keeler and weaker Meir-Keeler functions, respectively. In this way, we
extend several well-known fixed point theorems and, in particular, improve some very
recent results on weaker Meir-Keeler functions. Fixed point results for well-posed
property and for limit shadowing property are also deduced. Finally, an application to
the study of existence and uniqueness of solutions for a class of nonlinear integral
equations is presented.The second author thanks for the support of the Ministry of Economy and Competitiveness of Spain under grant MTM2012-37894-C02-01, and the Universitat Politecnica de Valencia, grant PAID-06-12-SP20120471.Nashine, HK.; Romaguera Bonilla, S.

J. S. Bach's WTC Book I Prelude and Fugue in B-flat Minor BWV 867: An Analysis and Study of Related Works
No full textabstract: The core element of this research paper is an analysis of the B-flat minor prelude and fugue BWV 867. The author’s analysis is then compared with the main contributors to Bach’s analytical studies. An understanding of the work’s structure, together with its motivic and harmonic details, help the performer develop an interpretive approach to the work.
Significant Bach scholars, including David Ledbetter and Peter Williams, are used as the source for the additional works to be studied. These scholars also mention close associates of Bach who offer additional insight into his music: Kirnberger and Weiss. The paper includes a brief discussion of the opening chorus fugue BWV 64, instrumental prelude to the cantata BWV 106, chorale prelude BWV 721, and Tombeau sur la Mort de Mr Comte de Logy by Weiss, as they relate to the B-flat minor prelude and fugue. In addition, the analysis provides materials on how the elements of the work relate to the Doctrine of Affections. From the B-flat minor prelude and fugue, the harmonic progressions and figuration are examined from the point of view of the Doctrine. The research also examines the fugue subject, with its unusual leap of a minor 9th, to its structural connection to the opening chorus fugue of BWV 64, and its ties to the Doctrine.
Through the analysis of the B-flat minor prelude and fugue and a comparison to works by Bach that are stylistically connected to this work, the author offers insights into the music and its relationship to works that have a sacred text association.Dissertation/ThesisDoctoral Dissertation Music 202

A Model for Chagas Disease with Oral and Congenital Transmission
No full textabstract: This work presents a new mathematical model for the domestic transmission of Chagas disease, a parasitic disease affecting humans and other mammals throughout Central and South America. The model takes into account congenital transmission in both humans and domestic mammals as well as oral transmission in domestic mammals. The model has time-dependent coefficients to account for seasonality and consists of four nonlinear differential equations, one of which has a delay, for the populations of vectors, infected vectors, infected humans, and infected mammals in the domestic setting. Computer simulations show that congenital transmission has a modest effect on infection while oral transmission in domestic mammals substantially contributes to the spread of the disease. In particular, oral transmission provides an alternative to vector biting as an infection route for the domestic mammals, who are key to the infection cycle. This may lead to high infection rates in domestic mammals even when the vectors have a low preference for biting them, and ultimately results in high infection levels in humans.The article is published at http://journals.plos.org/plosone/article?id=10.1371/journal.pone.006726
Education, Rent Seeking and Growth
No full textThis paper studies the role of education as a way of reducing private rent seeking activities and increasing output. In many underdeveloped economies, for most individuals, there is no private return to education. Nonetheless, according to this paper, governments are better off by investing in public education. We view education as a means to build personal character, thereby affecting macroeconomic long run equilibrium by reducing the number of individuals who are engaged in private rentseeking activities. We show that education is more efficient than ordinary law enforcement because it has a long-run effect. The policy implication of this result is that even when education does not increase human capital, compulsory schooling will be beneficial in pulling underdeveloped economies out of poverty.Rent Seeking, Decency, Education, Growth

Three Facets of Fazil Say in His Selected Piano Compositions
No full textabstract: Beginning around the 1820s, the refinement of the piano mechanism increased the expressiveness of the instrument’s sonority and further attracted the composers’ attention and curiosity about the instrument. Concentration on piano music became a trend for composers between the mid to late nineteenth century. During this period, the massive output of music for piano and extremely developed keyboard techniques resulted in classical composers searching for fresh ideas. Starting in the twentieth century, composers became increasingly interested in music outside the classical world and new interpretations of meter, harmony, and form. As early as the 1910s, composers included tone clusters generated at keyboard and soon afterwards, began “playing” the internal components of the piano including strings. Concurrently, they blended different styles within a piece according to their cultural and educational background. A prime example of this compositional trend is the classically-trained Turkish pianist-composer Fazil Say (b. 1970). His ability as a pianist reflects his strong classical training as well as a stylistic freedom partly derived from jazz. Say’s inspiration is also drawn from his Turkish heritage, as traditional folk elements have helped to shape his compositions. Representing Say’s education, passion, and ethnic background, the three elements of classical, jazz, and folk music have become his primary devices within his solo piano compositions.
This brief investigation of Say’s life to date and his piano works offers an insight into the correlation between the multi-cultural environments in which he has lived and the formation of his styles. Chapter one, the summary of his life and educational background, illustrates the fact that the three facets within his piano compositions are strongly rooted in his exposure to different environments. The second chapter presents a clear overview of the development of Say’s compositional idiom and a deeper look at selected piano compositions: his transcription of J. S. Bach’s Passacaglia in C Minor, BWV 582, Three Ballads, Black Earth, Alla Turca Jazz, and Paganini Jazz. The goal is to provide current and future pianists with insight into the expressive performance of one composer’s extremely successful hybridization of classical, jazz, and Turkish folk music.Dissertation/ThesisDoctoral Dissertation Music 201
Orthopedic complications related to growth hormone therapy in a pediatric population
No full textSince the introduction of recombinant growth hormone, its use has diversified and multiplied. Growth hormone is now the recommended therapy for a growing indication to all forms of short stature because of its direct and indirect role on bone growth. Hereby, we discuss the orthopedic complications associated with growth hormone treatment in pediatric patients. These complications include carpal tunnel syndrome, Legg-Calve-Perthes' disease, scoliosis, and slipped capital femoral epiphysis. Their incidence rates recorded in several growth hormone therapy-related pharmacovigilance studies will be summarized in this study with focused discussion on their occurrence in the pediatric and adolescent age groups. The pathogenesis of these complications is also reviewed. © 2011 Wolters Kluwer Health | Lippincott Williams and Wilkins.AHL T, 1988, SPINE, V13, P139, DOI 10.1097-00007632-198802000-00001; AlQattan MM, 1996, J HAND SURG-BRIT EUR, V21B, P108, DOI 10.1016-S0266-7681(96)80023-4; Bakker B, 2008, J CLIN ENDOCR METAB, V93, P352, DOI 10.1210-jc.2007-1581; Bell J, 2010, J CLIN ENDOCR METAB, V95, P167, DOI 10.1210-jc.2009-0178; Bjkerkreim I, 1976, Acta Orthop Scand, V47, P189; Blethen SL, 1996, J CLIN ENDOCR METAB, V81, P1704, DOI 10.1210-jc.81.5.1704; Blethen SL, 1996, HORM RES, V46, P113; Blethen SL, 1997, DRUG SAFETY, V17, P303, DOI 10.2165-00002018-199717050-00003; Bolar K, 2008, J CLIN ENDOCR METAB, V93, P344, DOI 10.1210-jc.2007-1723; Bowlby Deborah A, 2004, Pediatr Endocrinol Rev, V2 Suppl 1, P68; Carel JC, 2005, J CLIN ENDOCR METAB, V90, P3793, DOI 10.1210-jc.2005-0846; Clayton PE, 2000, GROWTH HORM IGF RES, V10, P306, DOI 10.1054-ghir.2000.0175; Cowell CT, 1995, J PEDIATR ENDOCR MET, V8, P243; Craig ME, 2006, CLIN ENDOCRINOL, V65, P178, DOI 10.1111-j.1365-2265.2006.02570.x; Darendeliler F, 2007, HORM RES, V68, P41, DOI 10.1159-000110474; Docquier Pierre-Louis, 2004, Acta Orthop Belg, V70, P299; DYMLING JF, 1978, ACTA ORTHOP SCAND, V49, P264; FIDLER MW, 1974, J BONE JOINT SURG AM, VA 56, P1719; Fillion M, 2009, J PEDIATR, V154, P230, DOI 10.1016-j.jpeds.2008.07.058; Fine RN, 2003, J PEDIATR, V142, P539, DOI 10.1067-mpd.2003.189; Franklin SL, 2009, ENDOCRIN METAB CLIN, V38, P587, DOI 10.1016-j.ecl.2009.06.006; Christiansen JS, 2001, J CLIN ENDOCR METAB, V86, P1868; Grumbach MM, 1998, HORM RES, V49, P41, DOI 10.1159-000053087; HARRIS WR, 1950, J BONE JOINT SURG BR, V32, P5; Helenius I, 2006, AM J TRANSPLANT, V6, P324, DOI 10.1111-j.1600-6143.2005.01135.x; HENRIKSO.B, 1969, ACTA ORTHOP SCAND, V40, P365, DOI 10.3109-17453676908989514; HOLM VA, 1981, DEV MED CHILD NEUROL, V23, P192; Jenkins PJ, 2000, ANN INTERN MED, V133, P197; KELSEY JL, 1970, J BONE JOINT SURG AM, VA 52, P1203; KEMBER NF, 1978, CELL TISSUE KINET, V11, P477, DOI 10.1111-j.1365-2184.1978.tb00820.x; KEMBER NF, 1971, CELL TISSUE KINET, V4, P193, DOI 10.1111-j.1365-2184.1971.tb01529.x; Kemp SF, 2005, J CLIN ENDOCR METAB, V90, P5247, DOI 10.1210-jc.2004-2513; Kim JY, 2001, J PEDIATR ORTHOPED, V21, P765, DOI 10.1097-00004694-200111000-00012; Kroonen LT, 2006, J PEDIATR ORTHOPED, V26, P673; Lehmann CL, 2006, J PEDIATR ORTHOPED, V26, P286; Maneatis T, 2000, J PEDIATR ENDOCR MET, V13, P1035; MORAIS T, 1985, AM J PUBLIC HEALTH, V75, P1377, DOI 10.2105-AJPH.75.12.1377; Nagai T, 2006, AM J MED GENET A, V140A, P1623, DOI 10.1002-ajmg.a.31295; Nakamura Y, 2009, SPINE J, V9, P809, DOI 10.1016-j.spinee.2009.06.017; Ohlsson C, 1998, ENDOCR REV, V19, P55, DOI 10.1210-er.19.1.55; Ong B C, 2001, Bull Hosp Jt Dis, V60, P94; Polgreen LE, 2009, BONE MARROW TRANSPL, V44, P279, DOI 10.1038-bmt.2009.31; Quigley CA, 2005, J CLIN ENDOCR METAB, V90, P5188, DOI 10.1210-jc.2004-2543; RAPPAPORT EB, 1987, AM J DIS CHILD, V141, P497; RENNIE W, 1974, J BONE JOINT SURG BR, VB 56, P703; SAKANO S, 1995, ARCH ORTHOP TRAUM SU, V114, P237, DOI 10.1007-BF00444271; SARNA S, 1995, TRANSPLANTATION, V60, P656, DOI 10.1097-00007890-199510150-00007; Seikaly MG, 2009, PEDIATR NEPHROL, V24, P1711, DOI 10.1007-s00467-009-1183-0; Smida Mahmoud, 2003, Acta Orthop Belg, V69, P458; Van Meir Nathalie, 2003, Acta Orthop Belg, V69, P387; VIMALACHANDRA D, 2001, COCHRANE DB SYST REV, V4; Wang ED, 1997, J PEDIATR ORTHOPED, V17, P708, DOI 10.1097-00004694-199711000-00003; Watkins SL, 1996, PEDIATR NEPHROL, V10, P351; Watkins S L, 1996, Kidney Int Suppl, V53, pS126; Wetterau L, 2000, HORM RES, V53, P31, DOI 10.1159-000023530; WILCOX PG, 1988, J PEDIATR ORTHOPED, V8, P196; WILTON P, 1999, GROWTH HORMONE THERA, P349; Wyatt D, 2004, EUR J ENDOCRINOL, V151, pS55, DOI 10.1530-eje.0.151S055; YOSHIKAZU N, 1998, ENDOCRINE J S, V45, pS16711
Stopping Hyperinflations Past and Present
No full textWe examine four successful stabilizations from high inflation -- Germany in 1923,Austria in 1922, in Poland 1924-27, Italy 1947 --and the two ongoing attempted stabilization in Israel and Argentina, with the aim of identifying general lessons from those episodes. The key issues in a stabilization are the budget, the exchange rate, and money. Budget deficits were significantly reduced in each case , but were not in all cases completely removed. The exchange rate was pegged in each case , through in all but the Italian case, each stabilization was also preceded by at least one episode in which attempted stabilization through exchange rate pegging was unsuccessful. As pointed out by Sargent and others , money growth rates were high after each stabilization, suggesting that any stabilization that strictly controls the growth of money will produce serious recession. A common feature of stabilizations is a period of extremely high real interest rates.
