Serious Games and Experiential Learning: Options for Engineering Education

This research delves into the use of simulation games as a learning tool in logistics education, with a focus on the Logistics Simulator and Production Game Simulator. Through an analysis of these two cases, relevant findings were uncovered. Firstly, simulation games can recreate concrete experiences, allowing students to engage with challenging problems in a practical manner. In addition, simulation games offer a platform for experimentation with diverse scenarios, enabling students to hone their decision-making skills in a safe environment. Furthermore, the degree of motivation and engagement exhibited by students was found to be positively correlated with their experience gained through simulators. However, while the results obtained from the simulator were associated with student motivation and engagement, the study did not yield conclusive evidence in terms of student learning outcomes. The findings underscore the significance of employing strategies that enhance student motivation and support deep learning, thereby enabling students to apply and transfer knowledge to new situations. Notably, simulation games have great potential in logistics education as they facilitate faster and more enjoyable comprehension of key decision-making factors. Nevertheless, limitations of this study include the small sample size in both cases, which restricts generalizability, and the lack of consideration for sociodemographic factors in the baseline survey. Future research should address these limitations for more reliable findings on the specific needs of students in game-based and experiential learning contexts

Frecuencia de enfermedad periodontal y caries en caninos del Centro de Zoonosis de Bogotá

Introduction: The research project entitled “Frequency of Periodontal Disease and Cavities in Dogs at the Bogotá Zoonosis Center” was carried in 2011out at the Universidad Antonio Nariño by the “Quirón” research group. Materials and Methods: A cross sectional study, which evaluated 100 dogs previously euthanized with sodium pentobarbital. The Lobprise and Wiggs veterinarian periodontal index was used to establish the presence of periodontal disease and three criteria were taken into account to evaluate cavities: brown spot lesions, white spot lesions and active cavitational cavities, following the established patterns in the three records systems, which included the medical history, dental chart and periodontogram. Results: 64% of the dogs tested had periodontal disease and 1% had cavities; 16% of patients had both diseases simultaneously. 64% of those with periodontal disease 30% had mild periodontitis, 20% had severe periodontitis, 13% moderate periodontitis and 1% had gingivitis. Conclusions: Greater tooth loss was observed in older dogs, premature loss is greater in dogs with severe periodontal disease and premolars were the teeth most affected. The frequency of peri- odontal disease was 80% and 17% for cavities. The results are consistent with those reported in the literature and show the importance of veterinarians knowing about problems associated with the canine oral cavity.  Introducción: el proyecto de investigación “Frecuencia de enfermedad periodontal y caries en caninos del Centro de Zoonosis de Bogotá” fue realizado en la Universidad Antonio Nariño, por el grupo de investigación “Quirón”, durante el 2011. Se determinó la frecuencia de presentación de enfermedad periodontal y caries en perros del Centro de Zoonosis de Bogotá. Materiales y métodos: se evaluaron 100 caninos que habían sido previamente eutanizados con pentobarbital sódico. Para establecer la presencia de enfermedad periodontal se usó el índice veterinario periodontal de Wiggs y Lobprise y para caries se tuvieron en cuenta tres criterios: lesión de mancha café, de mancha blanca y caries activa cavitacional, siguiendo los esquemas establecidos en los tres sistemas de registro, que incluyeron historia clínica, odontograma y periodontograma. Resultados: el 64% de los animales presentaron enfermedad periodontal y el 1% caries; en el 16% se presentaron las dos patologías  simultáneamente. Conclusiones: se observó una mayor pérdida de dientes en los perros de mayor edad, la pérdida prematura es mayor en caninos que presentan enfermedad periodontal severa y el tipo dentario más afectado fueron los premolares. La frecuencia de enfermedad periodontal fue del 80% y de 17% para caries. Los resultados encontrados están de acuerdo con los reportados por la literatura y demuestran la importancia de conocer los problemas asociados a la cavidad oral canina por parte de los médicos veterinarios

Compromising between European and US allergen immunotherapy schools: Discussions from GUIMIT, the Mexican immunotherapy guidelines

Background: Allergen immunotherapy (AIT) has a longstanding history and still remains the only disease-changing treatment for allergic rhinitis and asthma. Over the years 2 different schools have developed their strategies: the United States (US) and the European. Allergen extracts available in these regions are adapted to local practice. In other parts of the world, extracts from both regions and local ones are commercialized, as in Mexico. Here, local experts developed a national AIT guideline (GUIMIT 2019) searching for compromises between both schools. Methods: Using ADAPTE methodology for transculturizing guidelines and AGREE-II for evaluating guideline quality, GUIMIT selected 3 high-quality Main Reference Guidelines (MRGs): the European Academy of Allergy, Asthma and Immunology (EAACI) guideines, the S2k guideline of various German-speaking medical societies (2014), and the US Practice Parameters on Allergen Immunotherapy 2011. We formulated clinical questions and based responses on the fused evidence available in the MRGs, combined with local possibilities, patient's preference, and costs. We came across several issues on which the MRGs disagreed. These are presented here along with arguments of GUIMIT members to resolve them. GUIMIT (for a complete English version, see Supplementary data) concluded the following: Results: Related to the diagnosis of IgE-mediated respiratory allergy, apart from skin prick testing complementary tests (challenges, in vitro testing and molecular such as species-specific allergens) might be useful in selected cases to inform AIT composition. AIT is indicated in allergic rhinitis and suggested in allergic asthma (once controlled) and IgE-mediated atopic dermatitis. Concerning the correct subcutaneous AIT dose for compounding vials according to the US school: dosing tables and formula are given; up to 4 non-related allergens can be mixed, refraining from mixing high with low protease extracts. When using European extracts: the manufacturer's indications should be followed; in multi-allergic patients 2 simultaneous injections can be given (100% consensus); mixing is discouraged. In Mexico only allergoid tablets are available; based on doses used in all sublingual immunotherapy (SLIT) publications referenced in MRGs, GUIMIT suggests a probable effective dose related to subcutaneous immunotherapy (SCIT) might be: 50–200% of the monthly SCIT dose given daily, maximum mixing 4 allergens. Also, a table with practical suggestions on non-evidence-existing issues, developed with a simplified Delphi method, is added. Finally, dissemination and implementation of guidelines is briefly discussed, explaining how we used online tools for this in Mexico. Conclusions: Countries where European and American AIT extracts are available should adjust AIT according to which school is followed

Estimating the global conservation status of more than 15,000 Amazonian tree species

Estimates of extinction risk for Amazonian plant and animal species are rare and not often incorporated into land-use policy and conservation planning. We overlay spatial distribution models with historical and projected deforestation to show that at least 36% and up to 57% of all Amazonian tree species are likely to qualify as globally threatened under International Union for Conservation of Nature (IUCN) Red List criteria. If confirmed, these results would increase the number of threatened plant species on Earth by 22%. We show that the trends observed in Amazonia apply to trees throughout the tropics, and we predict thatmost of the world’s >40,000 tropical tree species now qualify as globally threatened. A gap analysis suggests that existing Amazonian protected areas and indigenous territories will protect viable populations of most threatened species if these areas suffer no further degradation, highlighting the key roles that protected areas, indigenous peoples, and improved governance can play in preventing large-scale extinctions in the tropics in this century

Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.

Search for stop and higgsino production using diphoton Higgs boson decays

Results are presented of a search for a "natural" supersymmetry scenario with gauge mediated symmetry breaking. It is assumed that only the supersymmetric partners of the top-quark (stop) and the Higgs boson (higgsino) are accessible. Events are examined in which there are two photons forming a Higgs boson candidate, and at least two b-quark jets. In 19.7 inverse femtobarns of proton-proton collision data at sqrt(s) = 8 TeV, recorded in the CMS experiment, no evidence of a signal is found and lower limits at the 95% confidence level are set, excluding the stop mass below 360 to 410 GeV, depending on the higgsino mass

Juxtaposing BTE and ATE – on the role of the European insurance industry in funding civil litigation

One of the ways in which legal services are financed, and indeed shaped, is through private insurance arrangement. Two contrasting types of legal expenses insurance contracts (LEI) seem to dominate in Europe: before the event (BTE) and after the event (ATE) legal expenses insurance. Notwithstanding institutional differences between different legal systems, BTE and ATE insurance arrangements may be instrumental if government policy is geared towards strengthening a market-oriented system of financing access to justice for individuals and business. At the same time, emphasizing the role of a private industry as a keeper of the gates to justice raises issues of accountability and transparency, not readily reconcilable with demands of competition. Moreover, multiple actors (clients, lawyers, courts, insurers) are involved, causing behavioural dynamics which are not easily predicted or influenced. Against this background, this paper looks into BTE and ATE arrangements by analysing the particularities of BTE and ATE arrangements currently available in some European jurisdictions and by painting a picture of their respective markets and legal contexts. This allows for some reflection on the performance of BTE and ATE providers as both financiers and keepers. Two issues emerge from the analysis that are worthy of some further reflection. Firstly, there is the problematic long-term sustainability of some ATE products. Secondly, the challenges faced by policymakers that would like to nudge consumers into voluntarily taking out BTE LEI

Optimasi Portofolio Resiko Menggunakan Model Markowitz MVO Dikaitkan dengan Keterbatasan Manusia dalam Memprediksi Masa Depan dalam Perspektif Al-Qur`an

Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis
