El aprendizaje en la organización
Authors: Quintero Ramírez Álvaro 
Published: November 2015

El desarrollo del aprendizaje en la organización es un proceso inherente a la persona y, por lo tanto, un hecho social. Los conocimientos que se generan por el aprendizaje que hacen las personas de sus procesos se encuentran depositados en sus experiencias y en sus saberes particulares; en los cuales recae, en buena parte, el éxito o el fracaso del éxito de su gestión. Para estimular la generación de este conocimiento la empresa debe crear espacios que faciliten el aprendizaje cotidiano y motiven a las personas a compartirlos para acrecentarlos y depurarlos por medio de un aprendizaje colectivo.
El aprendizaje significativo en el contexto educativo
Authors: Almeida Cantoni Alicia 
Published: November 2015

Actualmente es posible reconocer, en diferentes ámbitos académicos, la predominancia de prácticas educativas sucedáneas o artificiales, dado que el conocimiento se valora como neutral, autosuficiente e independiente de las prácticas sociales de la cultura de las situaciones cotidianas. El resultado de este tipo de prácticas son aprendizajes desprovistos de significado y sentido, reflejando como el estudiante se torna muy poco hábil para transferir y generalizarlo que aprende. En este ejemplo de aprendizajese da lugar a una ruptura entre el saber qué (know what) y el saber cómo (know how).

Authors: Sánchez Caimán Pedro José 
Published: November 2015

Actualmente, la investigación de operaciones es una herramienta útil en los proceso de diseño, ejecución y control de sistemas logísticos; sin embargo, una de las herramientas mas útiles es la simulación, la cual es una técnica asequible para la solución de problemas. Una de las primeras referencias en el tema de simulación se remonta al ano 1940 cuando el científico Ullman aplicó y diseño la técnica llamada "simulación Montecarlo". Más adelante la simulación inició una etapa de auge, mediante la aplicación en procesos en la industria aeroespacial, autopartista, de comunicaciones, entre otras; y actualmente se utiliza en diversas áreas del sector empresarial y Militar, corno es la logística, la producción, y últimamente en diversas actividades militares en todo el mundo, por ejemplo operaciones logísticas en la Guerra de lrak e Afganistan. El objetivo de este articulo es presentar una revisión crítica para quienes empiezan su investigación en el área de simulación de procesos logísticos y están interesados en la esta herramienta para mejorar la cadena de suministro en los niveles estratégico, táctico y operativo. En este articulo se presentará un marco teórico y conceptual que abordará la definición de simulación aplicada a la logística, sus principales aplicaciones, clasificación y metodología de desarrollo, información que introducirá al lector en este tipo de procesos de optimización.

Published: November 2015

The technology advances rapidly; as a result, education and instruction are getting digitalized. So it could be estimated that; pre-service teachers who are future teachers, should have digital skills.Â This is the main point of this study which aims to visit pre-service teachers in Turkey from the perspective of digital fluency, give insights about digital fluency, scrutinize its difference from digital literacy and provide literature review on the previous studies about digital fluency. At first, the connection between digital fluency and the 21st century analyzed, then the differences between digital literacy and digital fluency are described. Worldwide and specifically Turkish literature review revealed that, certain studies foresaw the increasing importance of digital fluency based on development of digital devices, and Turkish literature was limited to some scale development and descriptive studies solely determining the digital literacy level of the participants. Thus, it could be stated that further and up-to-date studies are required, which would be conducted with pre-service teachers and current assessment instruments should be developed to determine digital fluency level, considering the rapid advances in technology.Keywords: digital fluency, digital literacy, pre-service teachers.

Published: November 2015

Determination of the perceptions of the prospective teachers about Information and Communication Technology (ICT) terms has a remarkable potential to provide input for technology integration plans and ICT training. Within this context, the purpose of this study is to discover the metaphors constructed by prospective teachers for ICT terms. Data were gathered from 180 prospective teachers through a survey. 977 valid metaphors constructed by the participants were grouped into conceptual categories for the six ICT terms. The most common conceptual categories are â€œdeveloping and changingâ€ for technology, â€œmaking life easyâ€ for computers and search engines, â€œlimitless and endlessâ€ for the Internet, â€œmeans of communicationâ€ for social networks, and â€œaddictive itemsâ€ for video games. Future research should concentrate on investigating the match and mismatches between the intended use of the ICT tools and the perception of the prospective teachers.Â Keywords: metaphors, ICT, information and communication technology, technology integration, pre-service teacher, teacher education, prospective teachers.
Expression of Vascular Endothelial Growth Factor Has a Regulatory Role in Gingival Venules in Experimental Diabetes
Authors: Gyurkovics Milán , Nagy Izabella , Bodor Csaba , Székely Andrea D. , Dinya Elek , Rosivall László , Lohinai Zsolt 
Published: November 2015

Background: In the present study, the possible localization and role of vascular endothelial growth factor receptor type 2 (VEGFR2) in the regulation of gingival venules in a rat model of experimental diabetes are examined.Methods: Six weeks after streptozotocin premedication, Wistar male rats presenting blood sugar levels >20 mmol/L were selected for investigation. The VEGFR2 antagonist ZM323881 [5‐((7‐benzyloxyquinazolin‐4‐yl)amino)‐4‐fluoro‐2‐methylphenol‐hydrochloride] (20 μg/mL) was dripped onto the gingiva between the mandibular incisors. Changes in diameter of the selected gingival venule were measured by vital microscopy combined with digital photography at specified times. Immunohistochemical staining was used to localize VEGFR2. For controls, the same protocol was used on animals with normal blood sugar levels and healthy gingiva.Results: There was a significant difference between the baseline venule diameter of the diabetic and the control groups (47 ± 1 and 28 ± 2 μm, respectively). After 15, 30, and 60 minutes of local application of ZM323881, significant vasoconstriction was observed in the venules of diabetic rats compared with the baseline (81.4% ± 4.6%, 81.8% ± 4.4%, and 80.6% ± 5.1%, respectively). The control group showed no change in the venule diameter. The immunohistochemical analysis showed significantly increased VEGFR2 expression in the mast cells along the venules in the diabetic group, whereas mast cells were rarely found in the control group.Conclusions: The findings suggest that VEGF expression is increased in gingiva in experimentally induced diabetes. After VEGFR2 activation, the mast cell–derived vasodilatory and inflammatory mediators may contribute markedly to the concomitant changes in the microcirculation.
Use of Platelet‐Rich Fibrin Membrane in the Treatment of Gingival Recession: A Systematic Review and Meta‐Analysis
Authors: Moraschini Vittorio , Barboza Eliane dos Santos Porto 
Published: November 2015

Background: The aim of this systematic review is to evaluate the effects of platelet‐rich fibrin (PRF) membranes on the outcomes of clinical treatments in patients with gingival recession.Methods: Articles that were published before June 2015 were searched electronically in four databases without any date or language restrictions and searched manually in regular journals and unpublished studies. The eligibility criteria comprised randomized controlled trials (RCTs) and prospective controlled trials with follow‐up periods of ≥6 months that compared the performance of PRF to other biomaterials in the treatment of Miller Class I or II gingival recessions. For the meta‐analysis, the inverse variance method was used in fixed‐ or random‐effect models, which were chosen according to heterogeneity. The estimates of the intervention effects were expressed as the mean differences in percentages or millimeters.Results: Six RCTs and one prospective clinical trial are included in this review. Root coverage (RC) and clinical attachment level (CAL) did not differ significantly between the analyzed subgroups (P = 0.57 and P = 0.50, respectively). The keratinized mucosa width (KMW) gain was significantly greater (P = 0.04) in the subgroup that was treated with connective tissue grafts.Conclusion: The results of the meta‐analysis suggest that the use of PRF membranes did not improve the RC, KMW, or CAL of Miller Class I and II gingival recessions compared with the other treatment modalities.
A Familial Pattern of Multiple Idiopathic Cervical Root Resorption With a 30‐Year Follow‐Up
Authors: Neely Anthony L. , Thumbigere‐Math Vivek , Somerman Martha J. , Foster Brian L. 
Published: November 2015

Background: Multiple idiopathic cervical root resorption (MICRR) is a rare entity distinct from pathologic root resorption that occurs as a result of several local and systemic factors.Methods: This report describes a familial pattern of MICRR, including a recently identified case and a 30‐year follow‐up on previously described cases.Results: The previously reported father (aged 95 years) and son (aged 64 years), and the recently affected daughter (aged 61 years) recounted non‐contributory medical history. The resorptive lesions were asymptomatic, unassociated with any predisposing factors, and first identified during the fourth to sixth decades of life. All tooth types were affected, with posterior teeth being affected earlier and with greater frequency; however, distal root surfaces were never affected. The resorptive lesions were progressive in nature, with additional teeth becoming involved as the condition was followed over time. In many instances, surrounding alveolar bone extended into the existing resorptive defects, but without clinical evidence of ankylosis. Gingival tissues, periodontal probing, and tooth mobility were within normal limits. Microcomputed tomography of extracted teeth demonstrated that the lesions were more extensive than clinically evident and rarely invaded the pulp chamber. Histologically, many resorptive lesions were noted along the cementum surface, with evidence of isolated cemental repair. Management of MICRR focused on restoring damaged root surfaces and extracting teeth with extensive root resorption.Conclusions: MICRR is a challenging entity with unknown etiology and a lack of well‐established preventive and management strategies. The familial pattern noted in this report necessitates future studies to investigate the role of genetic components in MICRR development.

Objectives. Our aim was to estimate the effects of Healthy Families Massachusetts, a statewide home visiting program serving first-time adolescent parents, on parenting, child development, educational attainment, family planning, and maternal health and well-being. Methods. We used a randomized controlled trial design to randomly assign the 704 participants to a group receiving home visiting services or a control group. Between 2008 and 2012, telephone and in-person interviews were conducted and administrative data obtained at 12 and 24 months after enrollment. Intention-to-treat analyses compared group differences across 5 outcome domains: parenting, child health and development, educational and economic achievement, family planning, and parental health and well-being. Results. The home visiting program had a positive influence on parenting stress, college attendance, condom use, intimate partner violence, and engagement in risky behaviors. No negative findings were observed. Conclusions. A paraprofessional home visiting program specifically targeting young mothers appears effective in domains of particular salience to young parents and their infants and toddlers. Expanding participation in the program appears a worthy goal for program administrators and policymakers.

Results at thirteen months of follow-up were good, with a Constant shoulder score of 97 of 100 and a Western Ontario Rotator Cuff Index of 97.5%. Radiographs showed no signs of recurrent instability.

Conclusion:
Operative treatment of this rare shoulder girdle injury can yield good results.
Cuboid-Navicular Tarsal Coalition in an Adolescent Female Athlete
Authors: Kamiya Tomoaki , Watanabe Kota , Teramoto Atsushi , Yamashita Toshihiko 
Published: November 2015

Case:
A fourteen-year-old female shot-putter developed midfoot pain with activity that initially responded to nonoperative care. However, the symptoms subsequently returned and became persistent. Advanced imaging demonstrated a fibrous cuboid-navicular tarsal coalition. Surgical resection of the tarsal coalition was performed when the patient was seventeen years old, and she returned to sports activities postoperatively with no pain.

Conclusion:
Although fibrous cuboid-navicular tarsal coalition is a very rare condition, it should be considered as one cause of persistent midfoot pain in an adolescent athlete. Surgical resection of the tarsal coalition can lead to a resolution of symptoms.
Alkaptonuria-Associated Changes in Disc Degeneration
Authors: Gruber Helen E. , Hanley Edward N. 
Published: November 2015

Case:
A thirty-nine-year-old man with alkaptonuria presented with low back pain. Imaging demonstrated lumbar scoliosis, extensive irregularities of end-plate vertebral margins, and Thompson Grade-V disc degeneration. Six months later, the patient returned with a herniated L2-L3 disc. Minimally invasive disc surgery was performed, and harvested disc tissue showed marked extracellular matrix changes and ochronotic pigment deposits.

Conclusion:
Scattered previous literature is available regarding disc changes in alkaptonuria. Although rare, alkaptonuria appears to severely impact the disc as reflected by cellular and matrix inclusions that contribute to disc-cell pathology.
Mental Health Workers’ Views on Addressing Tobacco Use
Authors: Ashton Maxie , Lawn Sharon , Hosking Jessica R. 
Published: November 2015

Objective: The aims of this study were to assess mental health workers’ attitudes to addressing tobacco dependence with patients, to identify barriers that may prevent people with mental illness from receiving support, and determine workers’ recommendations for tobacco policy and practice change. Method: Questionnaires were sent to government and non-government mental health services in Adelaide, South Australia. The questionnaires asked workers to rate on a Likert rating scale their attitudes to addressing tobacco use with patients and to respond to qualitative questions about managing tobacco use within mental health services. Quantitative data were analysed using SPSS version 15.0 and qualitative data was coded by three researchers into categories or themes and then analysed. Results: Questionnaires (324) were received from staff across 45 organizations providing clinical and psychosocial services. More than two thirds of the participants felt it was important for mental health services to be involved in assisting patients to quit smoking; however, only 26% said they raised the issue of tobacco use with patients, often or as part of the assessment. Respondents on average felt approximately one third of their patients could quit or reduce tobacco use if they received nicotine replacement therapy, information and support. Most workers suggested changes to policy and practice within mental health services including smoke free areas and the provision of information and support. Discussion: The rate of tobacco use amongst people with mental illness is still very high with serious social and health consequences. Mental health workers are uniquely placed to assist patients to quit or reduce tobacco use. This study has shown many workers believe that it is important to address tobacco use with their patients as part of routine care and that mental health services should implement significant tobacco policy and practice change.
Calcium-Modulating Cyclophilin Ligand Is Essential for the Survival of Activated T Cells and for Adaptive Immunity
Authors: Chan Siaw-Li , Lindquist Lonn D. , Hansen Michael J. , Girtman Megan A. , Pease Larry R. , Bram Richard J. 
Published: November 2015

Abstract
Calcium-modulating cyclophilin ligand (CAML) is an endoplasmic reticulum resident protein that is widely expressed. Although it has been demonstrated to participate in the tail-anchored protein insertion pathway, its physiological role in the mature immune system is unknown. In this work, we show that mature, peripheral T cells require CAML for survival specifically following TCR-induced activation. In this study, we examined mature T cells from spleen and lymph nodes of tamoxifen-inducible CAML knockout mice (tCAML−/−). Whereas CAML-deficient T cells were able to express the early activation markers CD25 and CD69, and produce IL-2 normally upon stimulation, deficient cells proliferated less and died. Cells did not require CAML for entry into the S phase of the cell cycle, thus implicating its survival function at a relatively late step in the T cell activation sequence. In addition, CAML was required for homeostatic proliferation and for Ag-dependent cell killing in vivo. These results demonstrate that CAML critically supports T cell survival and cell division downstream of T cell activation.
