Concepciones de contabilidad en estudiantes de la instituci?n educactiva Manuel Murillo Toro jornada diurna grado once tres en la modalidad de administraci?n financiera

102 p. Recurso Electr?nicoEn la actualidad se puede percibir que la mayor?a de estudiantes cultivan sentimientos negativos por el ?rea de las matem?ticas, y todo lo que implica el uso de los n?meros, entre ellas la contabilidad; lo cual impide conocer las diferentes concepciones que tienen los estudiantes sobre la misma lo que a su vez en muchos casos se debe a que tienen un concepto errado de la misma, o no tienen unos fundamentos s?lidos en Matem?ticas dificultando el aprendizaje y todo lo que se derive de ella. Todo esto puede deberse a diferentes factores pedag?gicos, did?cticos, motivacionales, personales, sociales entre otros. Pues en cualquier carrera t?cnica, tecn?loga o universitaria incluye en su pensum acad?mico las Matem?ticas o la Contabilidad; por consiguiente se espera que estos conocimientos le permitan desempe?arse de una forma calculada y mesurada en cuanto a su vida personal, y el manejo de su dinero. Lo anterior llev? al equipo investigativo a plantearse la siguiente pregunta problema: ?Cu?les son las concepciones de la contabilidad en los estudiantes de la Instituci?n Educativa INEM Manuel Murillo Toro, jornada diurna del grado 11-3 de la ciudad de Ibagu? (Tolima)? En vista de lo anterior el presente ejercicio investigativo tuvo como objetivo identificar, analizar, modificar y fortalecer, la concepci?n de Contabilidad en estudiantes de la Instituci?n Educativa INEM Manuel Murillo Toro del grado 11-3. Para lo anterior se us? la Metodolog?a de investigaci?n ? Acci?n, la cual permite intervenir directamente en la situaci?n probl?mica. Como primera medida se seleccion? la instituci?n Educativa, seg?n las modalidades de profundizaci?n se escogi? la instituci?n Inem Manuel Murillo Toro por su modalidad de Contabilidad, en el programa de Administraci?n Financiera en articulaci?n con la Universidad del Tolima y un convenio interinstitucional con la Uniminuto, y en especial se escogi? el grado 11-3 puesto que estos estudiantes desde el grado 9? han escogido esta modalidad y est?n en proceso de culminaci?n de su formaci?n escolar, lo cual permite tener una visi?n general del programa y en particular los conocimientos de la asignatura de Contabilidad. En conclusi?n est? investigaci?n busc? servir como referente y como documento de consulta sobre el ?rea de la Contabilidad, el papel relevante del docente en la formaci?n de esta ?rea, las posibles herramientas a implementar dentro del proceso y su papel decisivo en las concepciones de los estudiantes sobre la Contabilidad. En vista de lo anterior se resalta la importancia de investigar en el aula, partiendo del contexto en que se encuentran inmersos los estudiantes, con el fin de dar respuesta a al desconocimiento de las concepciones que se presentan en el aprendizaje de la Contabilidad y de esta manera contribuir y facilitar el aprendizaje de la mismas de tal forma que estos comprendan la transcendencia de esta ?rea en su cotidianidad.Currently, it can preceived that the majority of students cultivate negative feelings in the area of mathematics, and everything that involves the use of numbers, including accounting. These negavie feelings toward mathematics impede the students from understanding different mathematical concepts or have the wrong idea of the concept or they do not have a strong foundation in Mathematics, and thus it makes it very difficult to learn anything that arises from the mathematical concept. All of this is due to different factors such as: pedagogical, educational, motivational, personal, and social factors among others. In any University, as mathematics is included in the curriculum, technical career or technology. Therefore, this knowlege of mathematics will allow you to enhance your personal life as well, including how you manage money. This, therefore lead the investigative team to ask this problematic question: What accounting concepts do the students from the Inem Manuel Murillo Toro School grade11-3 in the city of Ibague, Tolima have? In view of the above, the present investigative exercise was intended to identify, analyze, modify, y strengthen the conception of accounting for the students in the Educational Institute Inem Manual Murillo Toro from grades 11-3. The technique of research was used for the above action, which allows you to intervene directly in the problematic situation. The first step was selecting the educational institution according to the deepening modalities the Institution of Inem Manuel Murillo Toro was chosen due to its model of accounting, financial management, in coordination with the University of Tolima, and an interinstitutional with Uniminuto, and in special we chose grades 11-3 given that these students have chosen this avenue and are in the process of completing high school, which therefore allows to have a general vision or overview of the program and in particular the accounting.In finding, this investigation sought to serve as a reference and consultation document in the area of accounting, the role of the teacher in the training in this area, and possible tools to be implemented within the process. In view of the above highlights, the importance of research in the classroom, on the basis of the context in which they are immersed students, in order to respond to the various problems which arise in when learning about accounting, and in this way contribute and facilitate the learning of the same so that they understand the significance of this area in their daily lives.

Association between proton pump inhibitor therapy and clostridium difficile infection: a contemporary systematic review and meta-analysis.

Abstract Introduction Emerging epidemiological evidence suggests that proton pump inhibitor (PPI) acid-suppression therapy is associated with an increased risk of Clostridium difficile infection (CDI). Methods Ovid MEDLINE, EMBASE, ISI Web of Science, and Scopus were searched from 1990 to January 2012 for analytical studies that reported an adjusted effect estimate of the association between PPI use and CDI. We performed random-effect meta-analyses. We used the GRADE framework to interpret the findings. Results We identified 47 eligible citations (37 case-control and 14 cohort studies) with corresponding 51 effect estimates. The pooled OR was 1.65, 95% CI (1.47, 1.85), I2 = 89.9%, with evidence of publication bias suggested by a contour funnel plot. A novel regression based method was used to adjust for publication bias and resulted in an adjusted pooled OR of 1.51 (95% CI, 1.26–1.83). In a speculative analysis that assumes that this association is based on causality, and based on published baseline CDI incidence, the risk of CDI would be very low in the general population taking PPIs with an estimated NNH of 3925 at 1 year. Conclusions In this rigorously conducted systemic review and meta-analysis, we found very low quality evidence (GRADE class) for an association between PPI use and CDI that does not support a cause-effect relationship

This analysis was based on three tables, the first one was to know the line and the subline to which the degree works corresponded, the second table was diluted with specific data of each thesis, finally, a third one that allowed us to gather more information to initiate a deeper analysis of these works. Literature was a fundamental basis for the conscientious analysis developed, since it allowed us to observe each one of the works and to know important aspects such as to which literary genre it belonged? What reasons to develop these investigations? (The oral expression, dyslexia, Dysgraphia, muletillas, scenic panic, among others), finding that the narrative, lyrical and dramatic genres were always present in the execution of each of the investigations. Thus, the following subgenres were worked within the narrative genre: the story 67%, myths and legends 19%, the fable 7%, the novel 5% and the story 2%, we show that the story was the subgenre most worked, Since it allowed them to find more strategies for the development of the investigative process, within the lyrical genre, poetry 100% and to complete the dramatic genre in this way: theater 94% and drama with 6%. It should be noted that most of these investigations achieved the proposed objective. Keywords: Literature, literary genres: narrative, lyric and dramatic

Two-pion Bose-Einstein correlations in central Pb-Pb collisions at sNN\sqrt{s_{\rm NN}} = 2.76 TeV

The first measurement of two-pion Bose-Einstein correlations in central Pb-Pb collisions at $\sqrt{s_{\rm NN}} = 2.76$ TeV at the Large Hadron Collider is presented. We observe a growing trend with energy now not only for the longitudinal and the outward but also for the sideward pion source radius. The pion homogeneity volume and the decoupling time are significantly larger than those measured at RHIC.Comment: 17 pages, 5 captioned figures, 1 table, authors from page 12, published version, figures at http://aliceinfo.cern.ch/ArtSubmission/node/388

Suppression of charged particle production at large transverse momentum in central Pb-Pb collisions at sNN=2.76\sqrt{s_{\rm NN}} = 2.76 TeV

Inclusive transverse momentum spectra of primary charged particles in Pb-Pb collisions at $\sqrt{s_{_{\rm NN}}}$ = 2.76 TeV have been measured by the ALICE Collaboration at the LHC. The data are presented for central and peripheral collisions, corresponding to 0-5% and 70-80% of the hadronic Pb-Pb cross section. The measured charged particle spectra in $|\eta|<0.8$ and $0.3 < p_T < 20$ GeV/$c$ are compared to the expectation in pp collisions at the same $\sqrt{s_{\rm NN}}$, scaled by the number of underlying nucleon-nucleon collisions. The comparison is expressed in terms of the nuclear modification factor $R_{\rm AA}$. The result indicates only weak medium effects ($R_{\rm AA} \approx$ 0.7) in peripheral collisions. In central collisions, $R_{\rm AA}$ reaches a minimum of about 0.14 at $p_{\rm T}=6$-7GeV/$c$ and increases significantly at larger $p_{\rm T}$. The measured suppression of high-$p_{\rm T}$ particles is stronger than that observed at lower collision energies, indicating that a very dense medium is formed in central Pb-Pb collisions at the LHC.Comment: 15 pages, 5 captioned figures, 3 tables, authors from page 10, published version, figures at http://aliceinfo.cern.ch/ArtSubmission/node/98

Elliptic flow of charged particles in Pb-Pb collisions at 2.76 TeV

We report the first measurement of charged particle elliptic flow in Pb-Pb collisions at 2.76 TeV with the ALICE detector at the CERN Large Hadron Collider. The measurement is performed in the central pseudorapidity region (|$\eta$|<0.8) and transverse momentum range 0.2< $p_{\rm T}$< 5.0 GeV/$c$. The elliptic flow signal v$_2$, measured using the 4-particle correlation method, averaged over transverse momentum and pseudorapidity is 0.087 $\pm$ 0.002 (stat) $\pm$ 0.004 (syst) in the 40-50% centrality class. The differential elliptic flow v$_2(p_{\rm T})$ reaches a maximum of 0.2 near $p_{\rm T}$ = 3 GeV/$c$. Compared to RHIC Au-Au collisions at 200 GeV, the elliptic flow increases by about 30%. Some hydrodynamic model predictions which include viscous corrections are in agreement with the observed increase.Comment: 10 pages, 4 captioned figures, published version, figures at http://aliceinfo.cern.ch/ArtSubmission/node/389

Search for new phenomena in final states with an energetic jet and large missing transverse momentum in pp collisions at √ s = 8 TeV with the ATLAS detector

Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses 20.3 fb−1 of √ s = 8 TeV data collected in 2012 with the ATLAS detector at the LHC. Events are required to have at least one jet with pT > 120 GeV and no leptons. Nine signal regions are considered with increasing missing transverse momentum requirements between Emiss T > 150 GeV and Emiss T > 700 GeV. Good agreement is observed between the number of events in data and Standard Model expectations. The results are translated into exclusion limits on models with either large extra spatial dimensions, pair production of weakly interacting dark matter candidates, or production of very light gravitinos in a gauge-mediated supersymmetric model. In addition, limits on the production of an invisibly decaying Higgs-like boson leading to similar topologies in the final state are presente

Adiposity is Associated with Regional Cortical Thinning

BACKGROUND: Although obesity is associated with structural changes in brain grey matter, findings have been inconsistent and the precise nature of these changes is unclear. Inconsistencies may partly be due to the use of different volumetric morphometry methods, and the inclusion of participants with comorbidities that exert independent effects on brain structure. The latter concern is particularly critical when sample sizes are modest. The purpose of the current study was to examine the relationship between cortical grey matter and body mass index (BMI), in healthy participants, excluding confounding comorbidities and using a large sample size. SUBJECTS: A total of 202 self-reported healthy volunteers were studied using surface-based morphometry, which permits the measurement of cortical thickness, surface area and cortical folding, independent of each other. RESULTS: Although increasing BMI was not associated with global cortical changes, a more precise, region-based analysis revealed significant thinning of the cortex in two areas: left lateral occipital cortex (LOC) and right ventromedial prefrontal cortex (vmPFC). An analogous region-based analysis failed to find an association between BMI and regional surface area or folding. Participants' age was also found to be negatively associated with cortical thickness of several brain regions; however, there was no overlap between the age- and BMI-related effects on cortical thinning. CONCLUSIONS: Our data suggest that the key effect of increasing BMI on cortical grey matter is a focal thinning in the left LOC and right vmPFC. Consistent implications of the latter region in reward valuation, and goal control of decision and action suggest a possible shift in these processes with increasing BMI.We thank all the participants and the staff of the Wolfson Brain Imaging Centre.

Nutrient intake and risk of open-angle glaucoma: the Rotterdam Study

Open-angle glaucoma (OAG) is the commonest cause of irreversible blindness worldwide. Apart from an increased intraocular pressure (IOP), oxidative stress and an impaired ocular blood flow are supposed to contribute to OAG. The aim of this study was to determine whether the dietary intake of nutrients that either have anti-oxidative properties (carotenoids, vitamins, and flavonoids) or influence the blood flow (omega fatty acids and magnesium) is associated with incident OAG. We investigated this in a prospective population-based cohort, the Rotterdam Study. A total of 3502 participants aged 55 years and older for whom dietary data at baseline and ophthalmic data at baseline and follow-up were available and who did not have OAG at baseline were included. The ophthalmic examinations comprised measurements of the IOP and perimetry; dietary intake of nutrients was assessed by validated questionnaires and adjusted for energy intake. Cox proportional hazard regression analysis was applied to calculate hazard ratios of associations between the baseline intake of nutrients and incident OAG, adjusted for age, gender, IOP, IOP-lowering treatment, and body mass index. During an average follow-up of 9.7 years, 91 participants (2.6%) developed OAG. The hazard ratio for retinol equivalents (highest versus lowest tertile) was 0.45 (95% confidence interval 0.23–0.90), for vitamin B1 0.50 (0.25–0.98), and for magnesium 2.25 (1.16–4.38). The effects were stronger after the exclusion of participants taking supplements. Hence, a low intake of retinol equivalents and vitamin B1 (in line with hypothesis) and a high intake of magnesium (less unambiguous to interpret) appear to be associated with an increased risk of OAG
