Authors: Turakhia Samir K. , Hill Brian T. , Dufresne Scott D. , Nakashima Megan O. , Cotta Claudiu V. 
Published: August 2014

Abstract

Objectives:
Recently described, aggressive B-cell lymphomas with genetic abnormalities involving MYC and BCL2 have been shown to have a poor prognosis when treated with regimens for diffuse large B-cell lymphomas. Similar data on cases with concurrent MYC and BCL6 translocation are still scant. Moreover, little is known regarding the morphologic and immunophenotypic characteristics of these cases, which further complicates their identification. This study describes six cases of aggressive B-cell lymphoma with translocations involving MYC and BCL6.

Methods:
Six cases of large B-cell lymphoma with translocation involving MYC and BCL6 confirmed by fluorescence in situ were identified. The morphologic, immunophenotypic, and clinical features of the cases were examined.

Results:
All the patients were older women, and in 50% of cases, the presentation was extranodal. In two cases, the liver was involved at presentation. A starry-sky pattern was a constant feature of the cases in which the morphology could be reliably assessed. Five of six cases had an immunophenotype corresponding to the germinal center B cells, and only one was positive for BCL2, an immunophenotype reminiscent of that of Burkitt lymphoma.

Conclusions:
B-cell lymphomas with translocations involving MYC and BCL6 have morphologic and immunophenotypic features suggestive of Burkitt lymphoma or gray zone lymphoma, and they tend to be diagnosed mainly in women, often in extranodal locations.
Perceived Learning Outcomes from Participation in One Type of Registered Student Organization: Equestrian Sport Clubs
Authors: Mikulec Erin , McKinney Kathleen 
Published: August 2014

Abstract: Learning takes place both in and outside the classroom. While there are a studies that focus on the professional, developmental, and learning outcomes of participation in student organizations, there has been insufficient research on these outcomes in sport clubs specifically and no research in an equestrian setting. In this paper, we report on the results of an on-line, primarily qualitative, questionnaire study conducted with members of a collegiate student organization, the Equestrians, at a large Midwestern U.S. university, as well as schools with similar organizations within the region and across the nation. Students were asked their reasons for joining the club and perceptions of what they learned, beyond equestrian skills, from participation in the organization. The respondents reported equestrian and interpersonal reasons for joining, and that participation increased their development in a number of academic and professional areas, especially in terms of 1. work ethic/time management/balance, 2. collaboration/communication/teamwork, and 3. leadership.
A Curricular reform viewed through Bolman and Deal’s organizational frames
Authors: Lyon Lucinda J , Nadersahi Nader A , Nattestad Anders , Kachalia Parag , Hammer Daniel 
Published: August 2014

Professions exist to serve the needs of society, communities and, in the case of the dental profession, patients. Academic dental institutions strive to help meet these needs by educating and developing future practitioners, educators, researchers, and citizen leaders who serve the community and shape the changing environment in which they practice and provide care. The American Dental Association Commission on Change and Innovation affirms, “If dental educators are to meet these purposes, change and innovation in dental education must be responsive to evolving societal needs, practice patterns, scientific developments, and economic conditions”(Haden, et al., 2006). Guiding any institution through such authentic reform requires a number of strategies. Lee Bolman and Terrance Deal suggest four organizational constructs, or frames, through which to view a complex organization: Structural, Human Resource, Political and Symbolic (Bolman and Deal, 1997).“Like maps, frames are both windows on a territory and tools for navigation” (Bolman and Deal, 1997). This reflective case study examines a major curricular reform initiative in a North American school of dentistry through Bolman and Deal’s organizational frames.
Learner-centered environments: Creating effective strategies based on student attitudes and faculty reflection
Authors: Bishop Catharine F. , Caston Michael I. , King Cheryl A. 
Published: August 2014

Learner-centered environments effectively implement multiple teaching techniques to enhance students' higher education experience and provide them with greater control over their academic learning. This qualitative study involves an exploration of the eight reasons for learner-centered teaching found in Terry Doyle's 2008 book, Helping Students Learn in a Learner Centered Environment. Doyle's principles were investigated through the use of surveys, student focus group interviews, and faculty discussions to discover a deeper understanding of the effects a "learner-centered" teaching environment has on long term learning in comparison to a "teacher-centered" learning environment. These data revealed five primary themes pertaining to student resistance to learner-centered environments. The results assisted in the development of strategies educators can adopt for creating a successful learner-centered classroom.
Openness of versality via coherent functors
Authors: Hall Jack 
Published: August 2014

Abstract
We give a proof of openness of versality using coherent functors. As an application, we streamline Artin’s criterion for algebraicity of a stack. We also introduce multi-step obstruction theories, employing them to produce obstruction theories for the stack of coherent sheaves, the Quot functor, and spaces of maps in the presence of non-flatness.

Determinants of abortion decisions among Ghanaian university students
Authors: Appiah-Agyekum Nana Nimo , Sorkpor Constance , Ofori-Mensah Samuel 
Published: August 2014

Abstract
Background: Unsafe abortion accounts for a significant proportion of maternal and reproductive health related mortalities and complications in developing countries. In Ghana and sub-Saharan Africa in general, abortion remains a significant barrier to achieving the health related MDGs. Yet, there exist a dearth of information on the determinants of abortion decisions among adolescents, students and other populations at risk.
Objectives: This study explores the factors that are likely to influence abortion decisions among University students in Ghana. It also explores their knowledge and perceptions on abortion.
Methods: Data were collected from 142 randomly sampled students of the University of Ghana through focus group discussions. Questions focused on their knowledge on abortion and the key determinants of their decisions to abort. The results were recorded, transcribed, and analysed qualitatively using the thematic analysis approach.
Results: The students were knowledgeable on abortion. In making decisions on abortion, the students considered their education, religious beliefs, health, economic factors, and family.
Conclusions: Factors such as societal pressure and peer influence that, to date, have been the backbone of sexual and reproductive health, anti-abortion stigma, and unsafe abortion education and interventions have minimal influence on abortion decisions among the students. Rather, these interventions must focus on their education, religious beliefs, health, economic factors, and family to make maximum impact.
Synthesis and characterization of novel hydroxyl-terminated hyperbranched polyurethanes

Published: August 2014

Abstract
A series of novel hydroxyl-terminated hyperbranched polyurethanes (HBPUs) were synthesized via stepwise polymerization by diethanolamine (DEOA), isophorone diisocyanate (IPDI) and trimethylolpropane (TMP). It is interesting to note that the HBPUs can be purified by water. The HBPUs were characterized with 1H nuclear magnetic resonance (NMR), 13C NMR, Fourier transform infrared spectroscopy (FT-IR) and elemental analysis. The average degree of branching (DB) of HBPUs was calculated from the first generation to the fourth generation to be 1.00, 0.74, 0.59 and 0.57 by quantitative 13C NMR, respectively. The branching model and molecular structure of HBPUs were deduced by the 13C NMR and the value of DB. To investigate the changes of hydrogen bonding interaction in HBPUs with a variation in structure of different generations, the deconvolution of FT-IR spectra was carried out using Origin 7.0 software through the Gaussian curve-fitting method. The ratio of hydrogen-bonded -NH and -OH groups of HBPUs was calculated to be 80.8%, 85.1%, 84.8% and 85.4% from the first generation to the fourth generation by deconvoluted -NH and -OH zone, respectively. The interaction of hydrogen bonding and glass transition temperature (Tg) of HBPUs increased with the increase of generation. The trend of thermal stability and Tg coincide with the change of hydrogen-bonded interactions.

Abstract
We report on the in-situ synthesis of metal carbonyl complexes with short-lived isotopes of transition metals. Complexes of molybdenum,
technetium, ruthenium and rhodium were synthesized by thermalisation of products of neutron-induced fission of 249Cf in
a carbon monoxide-nitrogen mixture. Complexes of tungsten, rhenium, osmium, and iridium were synthesized by thermalizing short-lived
isotopes produced in 24Mg-induced fusion evaporation reactions in a carbon monoxide containing atmosphere. The chemical
reactions took place at ambient temperature and pressure conditions. The complexes were rapidly transported in a gas stream to
collection setups or gas phase chromatography devices. The physisorption of the complexes on Au and SiO2 surfaces was
studied. We also studied the stability of some of the complexes, showing that these start to decompose at temperatures above
300 ℃ in contact with a quartz surface. Our studies lay a basis for the investigation of such complexes with
transactinides.

Published: August 2014

Abstract
Qualitative and quantitative understanding of Po volatilization under
different conditions is of key importance for safety assessments of
lead-bismuth eutectic (LBE) based nuclear reactors, spallation targets and
accelerator driven systems. In this work we explore the possibilities of the
transpiration method in combination with simple models to study the
equilibrium and kinetics of Po evaporation from highly diluted solutions in
lead-bismuth eutectic between 600 and 1000 ℃ in Ar/5% H2 and Ar.
On the basis of evaporation experiments at various carrier gas flow rates,
we identified the conditions of vapor saturation allowing the determination
of equilibrium constants. From the limiting behavior at high flow rates,
values for the maximal evaporation rate of Po from LBE were estimated.
Measurements of evaporation as a function of time were consistent with the
assumption that polonium dissolved in LBE obeys Henry's law. A theoretical
analysis furthermore suggested that diffusion of polonium in LBE was not
a rate limiting factor for evaporation under vapor saturation conditions.
Newly determined values for the Henry constant of Po in LBE between 600 and
1000 ℃ were consistent with previously derived correlations.

Abstract
Electrochemistry of NpO2
2+/NpO2
+ couple in 1 M H2SO4 was studied on bare and
modified glassy carbon (GC) electrodes by cyclic voltammetry (CV), differential pulse voltammetry (DPV) and electrochemical impedance
spectroscopy (EIS). The modified electrode (SWCNTs-GC) was characterized by scanning electron microscopy (SEM). Electrocatalysis of
NpO2
2+/NpO2
+redox reaction was observed on SWCNT-GC electrode. The lower charge transfer resistance at
SWCNT-GC reflects faster rate of electron transfer reaction of Np(VI)/Np(V) couple. These results are interesting to develop
electroanalytical methodologies for neptunium determination using SWCNT modified electrode. To the best of our knowledge, this is the
first study on the electrocatalysis of neptunium on SWCNT modified electrode.

Abstract
The Finisterre-Huon Papuan language Nungon, like related languages, shows fusion of tense marking with number marking. Nungon is remarkable among Finisterre-Huon languages for an aspectual distinction conflated with evidentiality, and for the development of a formally marked realis Remote Future tense inflection with a formally unmarked irrealis counterpart. This paper presents the entire Nungon verbal inflectional system, including tense, aspect, status, subject and object indexing, referent tracking, and evidentiality.

Le marquage du nombre dans le parler occitan des Ramats (TO, Italie)
Authors: Sibille Jean 
Published: August 2014

Abstract
Dans les langues romanes standard, les systèmes de marquage du pluriel sont relativement simples. En revanche, certaines variétés romanes vernaculaires possèdent des systèmes complexes faisant appel, dans une même variété, à plusieurs procédés de marquage de natures différentes. Dans la variété étudiée, les substantifs se répartissent en dix classes: une classe de substantifs invariables et neuf classes dans lesquelles le pluriel peut être marqué: par un suffixe vocalique alternant (/vˈaʃͻ/ ‘vache’, pl. /vˈaʃɛ/), par allongement vocalique, ou par flexion interne (/ʃapˈal/ ‘chapeau’, pl. /ʃapˈɛju/). Il faut y ajouter, dans certaines variétés géographiquement et linguistiquement proches, le marquage par un morphème ‑/s/ agglutiné au radical. L’étude des systèmes de marquage du pluriel dans différentes variétés romanes non standard, pourrait contribuer à une meilleure compréhension de la façon dont interagissent les contraintes phonologiques, morphologiques et syntaxiques.
Construcciones causativas con la preposiciónanteen la lengua española
Authors: Unternbäumen Enrique Huelva 
Published: August 2014

AbstractEn el presente artículo ofrecemos un análisis detallado de las relaciones causativas codificadas por la construcción [SN VACCante SNACC] en la lengua española. Este análisis se lleva a cabo en dos niveles distintos: en el nivel intrínseco, relativo a la conceptuación de la naturaleza de la relación existente entre el evento causado y su sujeto y en el nivel extrínseco, relativo a la conceptuación de la relación entre el sujeto del evento causado y el evento causante. Para llevar a cabo la caracterización de la dimensión intrínseca recurrimos a los conceptos de la intersubjetividad y la volicionalidad. La dimensión extrínseca, por su parte, es analizada desde la perspectiva del modelo de la dinámica de fuerzas de Talmy (1988; 2000). El artículo proporciona, además, una caracterización general de la semántica de la preposiciónante.
Una información fonética del siglo XI sobre la [h] del español
Authors: Mascaró Joan 
Published: August 2014

Abstract
In the evolution of Latin F- to h and eventually to Ø a crucial element is the exact phonetic nature of F- and subsequent stages in the phonetic change. It will be presented and discussed a fragment of the XIth century in which a well-known Arabic author provides important metalinguistic information about the pronunciation of continuant back consonants and in particular the glottal fricative [h] by Romance speakers. This information corroborates and generalizes a similar albeit more particular piece of evidence presented and discussed by Diego Catalán in 1968, which also indicates that Spanish speakers had [h] in their phonetic inventories.
Evidence of Hermaphroditism and Sex Ratio Distortion in the Fungal Feeding Nematode Bursaphelenchus okinawaensis
Authors: Shinya Ryoji , Hasegawa Koichi , Chen Anthony , Kanzaki Natsumi , Sternberg Paul W 
Published: August 2014

Abstract
Nematodes have many different reproductive strategies along with their divergent life histories; the ability of hermaphrodite to self- and cross-fertilize is useful for genetic manipulation. Here, we demonstrate the hermaphroditism of the fungal feeding nematode Bursaphelenchus okinawaensis, which was formerly described as a parthenogenetic nematode, and we show its other unique sexual characteristics. To determine that it is hermaphroditic, we performed the following experiments: observation of the pronuclear and chromosome behavior during oogenesis and early embryogenesis; observation of spermatogenesis during the fourth larval stage; investigation of sperm utilization; and investigation of phenotypic segregation after cross-mating using a chemically induced visible mutant. We then investigated the mating preferences and spermatid size difference between males and hermaphrodites. B. okinawaensis males successfully mated only with sperm-depleted old hermaphrodites, and the spermatid sizes of males were almost the same as those of hermaphrodites. Moreover, the sex ratio of cross-fertilized progeny was highly skewed toward hermaphrodites. B. okinawaensis is phylogenetically distant from established model nematodes such as C. elegans and is more closely related to some economically relevant parasitic nematodes. This newly discovered hermaphroditic nematode has great potential for evolutionary and parasitological research.
Algoritmos Numéricos para el Problema de Restauración de Imágenes usando el Método de las Proyecciones Alternantes
Authors: Escalante René 
Published: August 2014

Los algoritmos de proyección han evolucionado a partir del algoritmo de proyección alternante propuesto por J. von Neumann en 1933, donde el espacio solución es la intersección de un número finito de subespacios o conjuntos convexos. Investigaciones recientes se han centrado en técnicas para acelerar la convergencia del método y explotar el multiprocesamiento.
n este trabajo consideramos el problema de restauración de imágenes. La mayoría de las técnicas desarrolladas para resolverlo han usado algoritmos iterativos; una de ellas consiste en usar proyecciones ortogonales alternantes.
Llevamos a cabo una revisión cronológica de las diferentes técnicas en las que se ha aplicado el método de las proyecciones ortogonales alternantes al problema de restauración de imágenes, hasta llegar al enfoque reciente de Combettes (1997-1999), en donde la restauración se basa en el cálculo de proyecciones aproximadas, en lugar de proyecciones exactas.

El siguiente trabajo brinda un análisis del orden de los errores de aproximación y de redondeo que se cometen al combinar esquemas numéricos de estrategia recorrectora, de la familia Adams–Moulton–Bashfort. Estos métodos se utilizan en el tratamiento numérico del problema de estimación en modelos definidos por sistemas din´amicos de EDO.
Nuestro propósito es disponer de una “familia o clase” de métodos que sean eficientes o al menos competitivos al abordar la resolución numérica de este tipo de problemas,
Esta estrategia es compatible con las tendencias actuales que emplean modelos con funciones objetivos mínimo-cuadradas para el ajuste de curvas, que usan métodos de optimización sin y con restricciones, para resolver un problema discretizado por un esquema numérico que puede ser implícito, semi-implícito o explícito.
