La transformación de la visión de John Quincy Adams sobre México
Authors: Rathbun Lyon 
Published: January 2016

<p>Este artículo analiza la actitud cambiante frente a México de John Quincy Adams, de ser el primer arquitecto de la expansión territorial de Estados Unidos en la época nacional temprana hasta convertirse en ardiente defensor de la integridad territorial de México en los años treinta. El autor se plantea también la siguiente pregunta: ¿Qué nos dice la transformación de John Quincy Adams sobre las relaciones más amplias entre Estados Unidos y México? El trabajo muestra cómo, durante la segunda década del siglo XIX, en la búsqueda de autosuficiencia y ampliación territorial de Estados Unidos, Adams valoraba poco el potencial cívico de México y era ansioso de adquirir Texas y otros territorios mexicanos. Con su derrota en las elecciones de 1828, se convirtió en opositor de la expansión jacksoniana. Al resistir la expansión de la esclavitud –y la posibilidad de que la república se convirtiera en un imperio conquistador- Adams se vio obligado, a pesar suyo, a defender la integridad de México.</p><p> </p>
La escultura monumental de Juan Soriano : entrevistas al artista plástico y a dos conocedores de sus obras
Authors: De Garay Graciela 
Published: January 2016

<p>Estudiar la vida y la obra del artista plástico Juan Soriano, a través de su testimonio y las miradas o relatos de otros, en este caso la licenciada en comunicación Martha González Escobar y el arquitecto Teodoro González de León, representa una oportunidad para observar, a nivel microscópico, la historia de México y del arte nacional. En este regreso simbólico al pasado que realiza el que cuenta una historia a partir de su propia historia, el entrevistador puede conocer las normas o reglas de la sociedad desde el interior de ésta, es decir a través de los individuos que las aceptan como estructurantes de sus vidas pero que a la vez las transgreden con sus propias elecciones marcadas por el deseo de ser lo deseado. Esto es precisamente lo que marca la biografía ordinaria como lo ha escrito Giovanni Levi, “Ningún sistema normativo está, de hecho, tan estructurado para eliminar toda posibilidad de elección consciente.”</p><p> </p><p> </p>
El proceso de antropización en el lago de Chapala
Authors: Ojeda Sampson Alejandra , Covarrubias Villa Francisco , Arceo Ortega María Guadalupe 
Published: January 2016

<p>El lago de Chapala, perteneciente a la cuenca Lerma-Chapala-Santiago, debe abordarse de manera totalizadora puesto que las actuales condiciones del sitio obedecen principalmente, a las acciones antrópicas que se han llevado a cabo tanto en la cuenca como en el lago mismo y desde la época prehispánica hasta hoy día. Es por esto que este estudio se realizó bajo el método de la dialéctica crítica con la intencionalidad de potenciar sus elementos constituyentes para que transite de un estado de deterioro ambiental y humano a uno de equilibrio y equidad social permitiendo así que recupere las relaciones sustentables que el hombre sostenía con el lugar.</p>

An Experiential Learning Approach To Teaching Social Entrepreneurship, Triple Bottom Line, And Sustainability: Modifying And Extending Practical Organizational Behavior Education (PROBE)
Authors: Gundlach Michael J. , Zivnuska Suzanne 
Published: January 2016

When teaching social entrepreneurship and sustainability, using an experiential learning approach can be more effective than a traditional lecture approach. Social and environmental entrepreneurs often have a deep passion for their work that is important for students to develop early in their careers. Experiential learning enables students to create and experience this passion for themselves, thereby preparing them with the motivational and emotional resources they may need to be successful in the future. We introduce Practical Organizational Behavior Education (PROBE) as one way of helping students develop this passion. PROBE was originally developed as a service-learning project for an undergraduate course in organizational behavior at a very small, private university. However, in this manuscript, we show how PROBE can be modified and extended to effectively teach business students about triple bottom line concepts, sustainability, and social entrepreneurship at the undergraduate and MBA levels within a large, public university system. We provide practical suggestions for instructors interested in implementing this approach in a broad variety of settings.
Improving Pedagogy Through The Use Of Dynamic Excel Presentations In Financial Management Courses
Authors: Mangiero George A. , Manley John , Mollica J. T. 
Published: January 2016

This paper discusses and illustrates the use of dynamic Excel presentations to improve learning in Financial Management courses. Through the use of such presentations, multiple and varied examples of important principles in Financial Management, which would ordinarily take an excessive amount of time to cover, can be considered within the time span of a single class. Two applications of these techniques are presented in this paper: (1) Time Value of Money -- Classic Retirement Annuity analysis and (2) Capital Structure Decisions -- EBIT-EPS Analysis. By using these Excel techniques to cover multiple examples under different initial conditions and assumptions, the authors contend that students gain a broader understanding of these financial problems and their solutions, than would otherwise be possible.
Determining The Optimal Values Of Exponential Smoothing Constants – Does Solver Really Work?
Authors: Ravinder Handanhal V. 
Published: January 2016

A key issue in exponential smoothing is the choice of the values of the smoothing constants used. One approach that is becoming increasingly popular in introductory management science and operations management textbooks is the use of Solver, an Excel-based non-linear optimizer, to identify values of the smoothing constants that minimize a measure of forecast error like Mean Absolute Deviation (MAD) or Mean Squared Error (MSE). We point out some difficulties with this approach and suggest an easy fix. We examine the impact of initial forecasts on the smoothing constants and the idea of optimizing the initial forecast along with the smoothing constants. We make recommendations on the use of Solver in the context of the teaching of forecasting and suggest that there is a better method than Solver to identify the appropriate smoothing constants.

A new characterization of A7 and A8
Authors: Asboei Alireza Khalili , Salehi Syyed Sadegh , Iranmanesh Ali 
Published: January 2016

Abstract Let G be a finite group and πe(G) be the set of element orders of G. Let k ∈ πe (G)and mk be the number of elements of order k in G. Set nse(G):={mk|k ∈ πe (G)}. It is proved that An are uniquely determined by nse(An), where n ∈ {4,5,6}. In this paper, we prove that if G is a group such that nse(G)=nse(An) where n ∈ {7,8}, then G ≅ An.
Monomial ideals of minimal depth
Authors: Ishaq Muhammad 
Published: January 2016

Abstract Let S be a polynomial algebra over a field. We study classes of monomial ideals (as for example lexsegment ideals) of S having minimal depth. In particular, Stanley's conjecture holds for these ideals. Also we show that if I is a monomial ideal with Ass(S/I) = {P1, P2, ..., Ps} and Pi ⊄ ∑s1=j≠i Pj for all i ∊ [s], then Stanley’s conjecture holds for S/I.

Authors: Rahim Abdur , Hussain Muhammad Medrar , Altaf Ihsan Ullah Khan 
Published: January 2016

<p>In the present study various solvent extracts from the leaves of<em> Fernandoa adenophylla</em> were screened for their phytochemical and antimicrobial potentials. Preliminary phytochemical screening of leaves extracts showed the presence of alkaloids, glycosides, flavonoids, terpenoids, tannins, steroids, reducing sugars and anthracenes. Fourier transform infrared spectroscopic studies showed the presence of different functional groups for compounds like alcohol, aldehydes and ketones, saturated and unsaturated hydrocarbons, amides, amines, carboxylic acids, esters, and ethers. All the extracts showed significant antibacterial activities when tested against eight multidrug resistant bacterial strains isolated from urinary tract infection patients. It was concluded that the leaves extracts of<em> F. adenophylla</em> have several vital phytochemical constituents and significant antibacterial activities against multidrug resistant bacterial strains causing urinary tract infections.</p><p> </p>
Proximités épistémologiques et stratégies professionnelles
Authors: Renisio Yann , Zamith Pablo 
Published: January 2016

Cet article analyse l’ensemble des qualifications aux fonctions de maître de conférences attribuées par le Conseil national des universités (CNU) entre 2005 et 2013 en effectuant deux types de traitement statistique. Le premier restitue un espace des relations entre disciplines sur la base des individus simultanément qualifiés par plusieurs sections du CNU. Le second rend compte du lien fort qui existe entre l’ouverture disciplinaire d’une section et les chances d’accès à un poste universitaire pour ses candidats. On soulève ainsi un enjeu important que les approches fondées sur la seule bibliométrie tendent à éluder : l’intrication des logiques académique et scientifique. Loin d’être aléatoire, la coqualification traduit à la fois des proximités épistémologiques et des stratégies d’insertion professionnelle. Dès lors, les déterminants sociaux qui favorisent, en amont, les dispositions à l’interdisciplinarité, et les logiques d’employabilité auxquelles elle semble répondre, en aval, permettent d’appréhender autrement les injonctions récentes à l’interdisciplinarité.
Transgresser les frontières en sciences humaines et sociales en France
Authors: Heilbron Johan , Bokobza Anaïs 
Published: January 2016

Fondé sur une analyse secondaire de l’enquête bibliométrique du CNRS sur les revues en SHS, cet article analyse le degré d’ouverture et de fermeture de sept disciplines en sciences humaines et sociales (sociologie, anthropologie, science politique, économie/gestion, histoire, philosophie, droit). Deux dimensions sont distinguées : l’ouverture vis-à-vis d’autres disciplines (indiquée par la proportion de références à des revues extra-disciplinaires) et l’ouverture internationale (indiquée par la proportion de références à des revues non-francophones). À partir de ces indicateurs, on constate que le poids des références intra-disciplinaires est toujours considérable, et que plus on monte dans la hiérarchie des revues, plus les revues citées sont des revues intra-disciplinaires. Rien n’indique donc la « fin » des disciplines et l’avènement d’un règne transdisciplinaire. Le poids de la « disciplinarité » varie cependant selon la discipline, opposant les disciplines fermées sur elles-mêmes (notamment économie/gestion, droit) aux disciplines plus ouvertes (sociologie). De façon analogue, l’ouverture internationale varie elle aussi considérablement, opposant les disciplines peu nationales (économie/gestion) aux disciplines les plus nationales (droit, sociologie). En tous cas, les revues citées ne sont pas « trans » ou « internationales », mais en réalité binationales, c’est-à-dire françaises ou américaines.

Simulations Produce Teamwork Attitude Changes Among Health Professions Students
Authors: Sweigart Linda I. , Umoren Rachel A. , Scott Patrician J. , Carlton Kay Hodson , Jones James A. , Truman Barbara , Gossett Evalyn J. 
Published: January 2016

Background:

The majority of the estimated 400,000 or more patient deaths per year in the United States are from preventable medical errors due to poor communication. Team training programs have been established to teach teamwork skills to health professions students. However, it is often challenging to provide this training at a physical site. A brief intervention using a virtual learning environment with TeamSTEPPS
®
-based scenarios is described.

Method:
Using a pretest–posttest design, the effects on teamwork attitudes in 109 health professional students from two institutions and multiple disciplines were measured using the TeamSTEPPS Teamwork Attitudes questionnaire.

Results:

Participants showed significant attitude changes in the categories of leadership, situation monitoring, mutual support, and communication (
p
⩽ .05), with significance in four of the six indicator attitudes in the communication section at the
p
⩽ .001 level.

Conclusion:

These findings indicate the potential impact that virtual learning experiences may have on teamwork attitudes in learners across professions on multiple campuses. [

Preparing Students for Success on Examinations: Readiness Assurance Tests in a Graduate-Level Statistics Course
Authors: Bartlett Ellis Rebecca J. , Carter-Harris Lisa , MacLaughlin Pam 
Published: January 2016

Background:
Formative feedback is one way to foster students' readiness for statistics examinations.

Method:

The use of Readiness Assurance Tests was examined as an educational intervention in which feedback was provided for both correct and incorrect responses in a graduate-level statistics course. Examination scores in the intervention group (
n
= 56) were compared with those in a control group (
n
= 42).

Results:

Intervention group examination scores significantly improved from 75.92 ± 14.52 on the Readiness Assurance Test to 90.06 ± 7.06,
p
< .001, on the midterm, and final examination scores improved from 78.23 ± 17.29 to 85.6 ± 6.98,
p
= .002. Intervention group midterm scores were significantly higher than those of the control group (90.06 ± 7.06 versus 79.7 ± 11.6,
p
< .001); however, no differences were found between the groups on the final examination (85.35 ± 9.46 versus 85.6 ± 6.98,
p
= .91).

Conclusion:

Use of Readiness Assurance Tests was an effective modality to increase student self-efficacy, learning experience, and, relative to a control group, midterm examination performance in statistics. [

Use of a Mobile Device Simulation as a Preclass Active Learning Exercise
Authors: Keegan Robert D. , Oliver M. Cecile , Stanfill Teresa J. , Stevens Kevin V. , Brown Gary R. , Ebinger Michael , Gay John M. 
Published: January 2016

Background:
Research shows that preclass activities introducing new material can increase student performance. In an effort to engage students in an active learning, preclass activity, the authors developed a mobile application.

Method:

Eighty-four nursing students were assigned a preclass reading exercise, whereas 32 students completed the preclass simulation scenario on their mobile device. All students completed the same electronic fetal monitoring (EFM) quiz 1 week following the lecture. The effects of reading or simulation on student quiz performance was evaluated with a student's paired
t
test, using an alpha of .05.

Results:

Students completing the preclass simulation scored higher on the EFM quiz, compared with students assigned the preclass reading (85% versus 70% correct answers,
p
= .01). Student survey data indicated that the mobile device simulation was perceived as an engaging and desirable instructional tool.

Conclusion:

Nursing students completing the mobile device EFM preclass simulation outperformed the students who were given the traditional reading assignment. [

Femtosecond Laser-Assisted LASIK Flap Complications
Authors: Santos Allisson Mario dos , Torricelli Andre A. M. , Marino Gustavo K. , Garcia Renato , Netto Marcelo V. , Bechara Samir J. , Wilson Steven E. 
Published: January 2016

PURPOSE:
To discuss intraoperative and postoperative femtosecond laser-assisted LASIK flap complications and their management.

METHODS:
Review of published literature.

RESULTS:
Flap creation is a critical step in LASIK. The femtosecond laser has improved the overall predictability and safety of the lamellar incision, but complications can still occur during or after flap creation. Although many complications (eg, epithelial ingrowth and flap striae) were reduced with the femtosecond laser application, other specific complications have emerged, such as vertical gas breakthrough, opaque bubble layer, and transient light-sensitivity syndrome.

CONCLUSIONS:
The application of femtosecond laser technology to LASIK flap creation has increased greatly since its introduction. These lasers have improved the safety and predictability of the lamellar incision step. The majority of the femtosecond laser-assisted flap complications can be well managed without significant effects on refractive outcomes.

Infiltration of CCR2+Ly6Chigh Proinflammatory Monocytes and Neutrophils into the Central Nervous System Is Modulated by Nicotinic Acetylcholine Receptors in a Model of Multiple Sclerosis
Authors: Jiang Wei , St-Pierre Stéphanie , Roy Patrick , Morley Barbara J. , Hao Junwei , Simard Alain R. 
Published: January 2016

Abstract
Myeloid cells, including proinflammatory monocytes and neutrophils, have important roles in the pathology of multiple sclerosis and its animal model, experimental autoimmune encephalomyelitis (EAE). These cells infiltrate the CNS in the early stages of disease development and contribute to the inflammatory response that is associated with symptom severity. It is thus crucial to identify and understand new mechanisms that can regulate the CNS infiltration of proinflammatory myeloid cells. Nicotinic acetylcholine receptors (nAChRs) have been increasingly studied for their immune-regulatory properties. In this study, we assessed the ability of nicotine, an nAChR ligand, to modulate proinflammatory myeloid cell numbers within the bone marrow, spleen, blood, and CNS of EAE mice. We found that nicotine significantly inhibits the infiltration of proinflammatory monocytes and neutrophils into the CNS at time points where these cells are known to play critical roles in disease pathology. In contrast, nicotine does not affect the expansion of other monocytes. We also show that nicotine exerts these effects by acting on α7 and α9 nAChR subtypes. Finally, mRNA transcript levels for CCL2 and CXCL2, chemokines involved in the chemotaxis of proinflammatory monocytes and neutrophils, respectively, are reduced in the brain of nicotine-treated EAE mice before the massive infiltration of these cells. Taken together, our data provide evidence that nAChRs can regulate proinflammatory cell infiltration into the CNS, which could be of significant value for the treatment of neuroinflammatory disorders.
Interplay between Target Sequences and Repair Pathways Determines Distinct Outcomes of AID-Initiated Lesions

Published: January 2016

Abstract
Activation-induced deaminase (AID) functions by deaminating cytosines and causing U:G mismatches, a rate-limiting step of Ab gene diversification. However, precise mechanisms regulating AID deamination frequency remain incompletely understood. Moreover, it is not known whether different sequence contexts influence the preferential access of mismatch repair or uracil glycosylase (UNG) to AID-initiated U:G mismatches. In this study, we employed two knock-in models to directly compare the mutability of core Sμ and VDJ exon sequences and their ability to regulate AID deamination and subsequent repair process. We find that the switch (S) region is a much more efficient AID deamination target than the V region. Igh locus AID-initiated lesions are processed by error-free and error-prone repair. S region U:G mismatches are preferentially accessed by UNG, leading to more UNG-dependent deletions, enhanced by mismatch repair deficiency. V region mutation hotspots are largely determined by AID deamination. Recurrent and conserved S region motifs potentially function as spacers between AID deamination hotspots. We conclude that the pattern of mutation hotspots and DNA break generation is influenced by sequence-intrinsic properties, which regulate AID deamination and affect the preferential access of downstream repair. Our studies reveal an evolutionarily conserved role for substrate sequences in regulating Ab gene diversity and AID targeting specificity.
Extensive CD4 and CD8 T Cell Cross-Reactivity between Alphaherpesviruses

Abstract
The Alphaherpesvirinae subfamily includes HSV types 1 and 2 and the sequence-divergent pathogen varicella zoster virus (VZV). T cells, controlled by TCR and HLA molecules that tolerate limited epitope amino acid variation, might cross-react between these microbes. We show that memory PBMC expansion with either HSV or VZV enriches for CD4 T cell lines that recognize the other agent at the whole-virus, protein, and peptide levels, consistent with bidirectional cross-reactivity. HSV-specific CD4 T cells recovered from HSV-seronegative persons can be explained, in part, by such VZV cross-reactivity. HSV-1–reactive CD8 T cells also cross-react with VZV-infected cells, full-length VZV proteins, and VZV peptides, as well as kill VZV-infected dermal fibroblasts. Mono- and cross-reactive CD8 T cells use distinct TCRB CDR3 sequences. Cross-reactivity to VZV is reconstituted by cloning and expressing TCRA/TCRB receptors from T cells that are initially isolated using HSV reagents. Overall, we define 13 novel CD4 and CD8 HSV–VZV cross-reactive epitopes and strongly imply additional cross-reactive peptide sets. Viral proteins can harbor both CD4 and CD8 HSV/VZV cross-reactive epitopes. Quantitative estimates of HSV/VZV cross-reactivity for both CD4 and CD8 T cells vary from 10 to 50%. Based on these findings, we hypothesize that host herpesvirus immune history may influence the pathogenesis and clinical outcome of subsequent infections or vaccinations for related pathogens and that cross-reactive epitopes and TCRs may be useful for multi-alphaherpesvirus vaccine design and adoptive cellular therapy.
