Representation of Minorities Displayed on College Webpages

Advertisements play an important role in nearly everyone\u27s life. Every single day people view a wide range of advertisements. With the population of America becoming more and more diverse in terms of race it would make sense that advertisements would reflect that same concept. However, it does not appear that advertisements actually reflect this idea. In the 2010 ads for the Super Bowl, only four out of the sixty-seven featured an African American in an ad. (Lapchick, 2010) Not only are minorities not being adequately represented in advertisements but they also only get featured for certain ads. African Americans find themselves featured in ads for beauty whereas Asians are found more in ads for technology. (Sheehan, 2014) There is obviously a misrepresentation of minorities in ads however, what is currently unknown is if this is true when it comes to college ads. Nearly every college, if not all, are advertising their schools so that more and more people will attend their school. The true question is whether or not college ads have continued with the mainstream ideals of advertising. A way to analyze this is by selecting 3 universities and 3 community or junior colleges by random and then looking at students presented on their website front page. Students who were being showcased on the website are students interacting with each other and are singled out for a variety of reasons. By comparing how many times a minority student appears in an advertisement versus what the overall percentage that minority group makes up at that specific school, one could determine whether or not that minority group is being adequately represented in ads. This is important because schools could possibly not be representing what their student demographics show. Just in all types of other advertisements this could affect how someone views a school and potentially how someone selects a school. This deeply impacts both the students and the schools

Sharp weighted estimates for approximating dyadic operators

We give a new proof of the sharp weighted $L^2$ inequality ||T||_{L^2(w)} \leq c [w]_{A_2} where $T$ is the Hilbert transform, a Riesz transform, the Beurling-Ahlfors operator or any operator that can be approximated by Haar shift operators. Our proof avoids the Bellman function technique and two weight norm inequalities. We use instead a recent result due to A. Lerner to estimate the oscillation of dyadic operators.Comment: To appear in the Electronic Research Announcements in Mathematical Science

Discussion of the phenomenon of serial HIV testers

Those who present repeatedly for unnecessary HIV testing are a common feature within HIV testing services worldwide. These 'worried well' tend no have low or non-existent levels of risk but despite this continually receive HIV testing when a more appropriate management strategies may exist. This discussion examines this phenomenon and related ones in detail and proposes possible solutions

Context-aware Assessment Using QR-codes

In this paper we present the implementation of a general mechanism to deliver tests based on mobile devices and matrix codes. The system is an extension of Siette, and has not been specifically developed for any subject matter. To evaluate the performance of the system and show some of its capabilities, we have developed a test for a second-year college course on Botany at the School of Forestry Engineering. Students were equipped with iPads and took an outdoor test on plant species identification. All students were able to take and complete the test in a reasonable time. Opinions expressed anonymously by the students in a survey about the usability of the system and the usefulness of the test were very favorable. We think that the application presented in this paper can broaden the applicability of automatic assessment techniques.The presentation of this work has been co-founded by the Universidad de Málaga.

IMPACT OF SUPREME AUDIT INSTITUTIONS ON THE PHENOMENON OF CORRUPTION: AN INTERNATIONAL EMPIRICAL ANALYSIS

This paper identiies the type of incidence of the Supreme Audit Institutionson the phenomenon of corruption, through statistical analysisfor a sample of 78 countries. Statistical methodology for panel datais used. The results demonstrate that is statistical evidence of positiveeffects. Fixed effects across countries are different, which demonstratethat there are, for each unit of study differential effects of control oncorruption. It cannot be interpreted the degree of impact, nonethelessthe results are robust and signiicant

Learning Bayesian Networks for Student Modeling

In the last decade, there has been a growing interest in using Bayesian Networks (BN) in the student modelling problem. This increased interest is probably due to the fact that BNs provide a sound methodology for this difficult task. In order to develop a Bayesian student model, it is necessary to define the structure (nodes and links) and the parameters. Usually the structure can be elicited with the help of human experts (teachers), but the difficulty of the problem of parameter specification is widely recognized in this and other domains. In the work presented here we have performed a set of experiments to compare the performance of two Bayesian Student Models, whose parameters have been specified by experts and learnt from data respectively. Results show that both models are able to provide reasonable estimations for knowledge variables in the student model, in spite of the small size of the dataset available for learning the parametersUniversidad de Málaga.

Pruning dominated policies in multiobjective Pareto Q-learning

The solution for a Multi-Objetive Reinforcement Learning problem is a set of Pareto optimal policies. MPQ-learning is a recent algorithm that approximates the whole set of all Pareto-optimal deterministic policies by directly generalizing Q-learning to the multiobjective setting. In this paper we present a modification of MPQ-learning that avoids useless cyclical policies and thus improves the number of training steps required for convergence.Supported by: the Spanish Government, Agencia Estatal de Investigaci´on (AEI) and European Union, Fondo Europeo de Desarrollo Regional (FEDER), grant TIN2016-80774-R (AEI/FEDER, UE); and Plan Propio de Investigación de la Universidad de Málaga - Campus de Excelencia Internacional Andalucía Tech

Exploratory Factorial Model of Perceived Safety in the COVID-19 Era

The perception of the police action in the face of Covid-19 was the objective of this work. A cross-sectional, psychometric and correlational study was carried out with a sample of 100 students, considering their participation in the public health system as social servants or professional practitioners through a platform. A four-factor structure was found that explained 63% of the total variance, although the findings are only applicable to the sample, and its extension to other scenarios is recommended

Extensión multi-índice del método beta en valoración agraria

[EN] The aim of this paper is the study and generalization of the method of the two distribution functions, used in the theory of valuation and, more concretely, in the agrarian valuations. The basic foundation of this method, proposed by Ballestero (1973), is the use of a representative index of the asset that we try to value and in the acceptance of a series of hypotheses on the distribution of the variable index and of the variable value of the asset. Until this moment and in all the works published on this method, the limitation of using a single index (although this is a synthesis of several to which it tries to represent) has remained. In this work it is presented a method that generalizes the previous one and that allows us to work with more than an index, so that it is possible not only to determine the value of an asset with reference to an index but to several ones. The method allows to work with different distribution functions of those used to treat the risk and it presents a test of acceptance of the functions used to model the indexes. Finally, a practical case is developed.[ES] El objetivo de este artículo es el estudio y generalización del método de las dos funciones de distribución, utilizado en la teoría de valoración y, más concretamente, en las valoraciones agrarias. El fundamento básico de este método, propuesto por Ballestero (1973), está en la utilización de un índice representativo del activo que pretendemos valorar y en la aceptación de una serie de hipótesis sobre la distribución de la variable índice y de la variable valor del activo. Hasta este momento y en todos los trabajos publicados sobre este método, se ha mantenido la limitación de utilizar un solo índice (aunque éste sea una síntesis de varios a los que pretende representar). En este trabajo se presenta un método que generaliza el anterior y que permite trabajar con más de un índice, de modo que sea posible determinar el valor de un activo con referencia no sólo a un índice sino a varios. El método permite trabajar con diferentes funciones de distribución de las utilizadas para tratar el riesgo y presenta un test de aceptación de las funciones utilizadas para modelar los índices. Finalmente, se desarrolla un caso práctico.García Pérez, J.; Cruz Rambaud, S. (2002). A multi-index extension of the beta agricultural evaluation method.
