Adapting Formal Logic for Everyday Mathematics
2022
Although logic is considered central to mathematics and computer science, there is evidence that teaching logic has not been a great success. We identify three issues where what is typically taught conflicts with what is needed by those who are supposed to apply logic. First, what is taught about the notion of implication often disagrees with human intuition. We argue that in some cases human intuition is wrong, and in some others teaching is to blame. Second, the formal concepts of logical consequence, logical equivalence and tautology are not the similar concepts that everyday mathematicians and computer scientists need. The difference is small enough to go unnoticed but big enough to cau…
La auditoria como medio de fiscalizacion de las cuentas públicas mexicanas
2017
Abstract: In this article we present the background of control in Mexico, which plays a key role in the LVII Legislature (1997-2000), where it constitutes a new and stronger supreme audit institution, promulgated in December 2000 the Law Audit Institutions of the Federation. Likewise, an analysis of the types of audits conducted Superior Audit of the Federation, each defining and specifying its objectives. It refers to the powers available to the Superior Audit of the Federation, which are conferred on the Supreme Audit Law of the Federation to carry out reviews and audits of public accounts. Moreover, an analysis of the types of opinions issued by this body to the auditees for reporting ye…
Buone pratiche e strumenti di analisi per l’apprendimento, l’insegnamento e l’inclusione
2022
Il presente lavoro, nato in seno al progetto di ricerca “Best practices and tools of analysis in schools and community contexts: learning, teaching & inclusion”, avviato su fondi del Dipartimento SPPEFF dell’Università di Palermo, nel marzo 2019 e giunto alla sua seconda fase. La metodologia di ricerca utilizzata – perché ritenuta adeguata a perseguire le finalità fissate e a fornire una visione complessa ed articolata del fenomeno investigato – è stata quella del Mixed Method, con particolare riferimento all’Explanatory Design: Participant Selection Model di Creswell, Plano Clark, et al. (2003). L’«Explanatory Design is a two-phase mixed methods design. The overall purpose of this desi…
Diseño, síntesis y evaluación de quimiodosímetros para la detección de formaldehído
2020
La presente tesis doctoral titulada “Diseño, síntesis y evaluación de quimiodosímetros para la detección de formaldehído” está centrada en el desarrollo de sistemas para la detección cromo-fluorogénica de formaldehído, tanto en disolución acuosa como en fase gas, empleando conceptos de química orgánica, química supramolecular y ciencia de los materiales. El formaldehído es una molécula ampliamente utilizada en distintos sectores industriales como la industria del mueble, farmacéutica o el sector textil. Sin embargo, su toxicidad pone en riesgo tanto a consumidores como a los trabajadores de dichos sectores, lo que convierte el desarrollo de sensores para detectar y monitorizar los niveles a…
Definición y unidades de las constantes de equilibrio en los libros de texto de Química general preuniversitarios y universitarios
2021
En este trabajo, una vez definidas las constantes de equilibrio experimentales, Kp y Kc, así como la constante de equilibrio termodinámica, Kº, se analiza su incorrecto tratamiento por parte de libros de texto de química general. Se expone la forma en que libros de química general de universidad y de bachillerato manejan las unidades de las constantes de equilibrio. Muchos textos no expresan con unidades los valores de Kp y Kc calculados. Además, en la mayoría de los casos, Kº no se define, y como resultado existe una confusión muy extendida acerca de estos conceptos. Este problema terminológico ocasiona que en muchos libros se confunda Kp con Kº. Se propone que la definición correcta de la…

IAEA Contribution to Nanosized Targeted Radiopharmaceuticals for Drug Delivery.
2022
The rapidly growing interest in the application of nanoscience in the future design of radiopharmaceuticals and the development of nanosized radiopharmaceuticals in the late 2000′s, resulted in the creation of a Coordinated Research Project (CRP) by the International Atomic Energy Agency (IAEA) in 2014. This CRP entitled ‘Nanosized delivery systems for radiopharmaceuticals’ involved a team of expert scientist from various member states. This team of scientists worked on a number of cutting-edge areas of nanoscience with a focus on developing well-defined, highly effective and site-specific delivery systems of radiopharmaceuticals. Specifically, focus areas of various teams of scientists com…
