Temas selectos de diseño e interacción tecnológica

76 Páginas.El libro en cuestión, presenta avances de tres trabajos de investigación que a su vez reflejan tres miradas distintas a la relación entre el diseño y las tecnologías digitales. El primer trabajo denominado “Diálogo desde las universidades, un punto de partida”, elaborado por la Mtra. Itzel Sainz, es una primera aproximación teórica que contribuye a mejorar el entendimiento sobre las modalidades de aplicación del diseño en los distintos medios de comunicación gráfica que aplican las instituciones públicas de educación superior en los espacios virtuales. Por su parte, el Dr. Marco Ferruzca nos comparte a través de su texto “Inteligencia colectiva y las prácticas del diseño” una breve reseña sobre cómo este fenómeno colectivo está incidiendo en la actividad proyectual del diseño de espacios, objetos, mensajes u otros tipos de diseño. El tercer texto “Análisis de movimientos oculares a partir de la lectura en línea de dos periódicos nacionales desde la perspectiva del diseño: el caso de los periódicos “El Universal” y “La Jornada”, dirigido por la Mtra. Ivonne Murillo y la Mtra. Alejandra Zafra, con la participación de Ramses Román alumno de Diseño Industrial, el profesor invitado Roberto López y un servidor; el trabajo es un ejemplo de ese otro tipo de argumentos más objetivos que los diseñadores pueden emplear para evaluar el objeto de diseño, en este caso los mensajes gráficos

Preliminary Evidence of EEG Connectivity Changes during Self-Objectification of Workers

Economic objectification is a form of dehumanization in which workers are treated as tools for enhancing productivity. It can lead to self-objectification in the workplace, which is when people perceive themselves as instruments for work. This can cause burnout, emotional drain, and a modification of self-perception that involves a loss of human attributes such as emotions and reasoning while focusing on others’ perspectives for evaluating the self. Research on workers self-objectification has mainly analyzed the consequences of this process without exploring the brain activity that underlies the individual’s experiences of self-objectification. Thus, this project explores the electroencephalographic (EEG) changes that occur in participants during an economic objectifying task that resembled a job in an online store. After the task, a self-objectification questionnaire was applied and its resulting index was used to label the participants as self-objectified or non-self-objectified. The changes over time in EEG event-related synchronization (ERS) and partial directed coherence (PDC) were calculated and compared between the self-objectification groups. The results show that the main differences between the groups in ERS and PDC occurred in the beta and gamma frequencies, but only the PDC results correlated with the self-objectification group. These results provide information for further understanding workers’ self-objectification. These EEG changes could indicate that economic self-objectification is associated with changes in vigilance, boredom, and mind-wandering

Novel Organotin(IV) Schiff Base Complexes with Histidine Derivatives: Synthesis, Characterization, and Biological Activity

Five novel tin Schiff base complexes with histidine analogues (derived from the condensation reaction between L-histidine and 3,5-di-tert-butyl-2-hydroxybenzaldehyde) have been synthesized and characterized. Characterization has been completed by IR and high-resolution mass spectroscopy, 1D and 2D solution NMR (1H, 13C  and 119Sn), as well as solid state 119Sn NMR. The spectroscopic evidence shows two types of structures: a trigonal bipyramidal stereochemistry with the tin atom coordinated to five donating atoms (two oxygen atoms, one nitrogen atom, and two carbon atoms belonging to the alkyl moieties), where one molecule of ligand is coordinated in a three dentate fashion. The second structure is spectroscopically described as a tetrahedral tin complex with four donating atoms (one oxygen atom coordinated to the metal and three carbon atoms belonging to the alkyl or aryl substituents), with one molecule of ligand attached. The antimicrobial activity of the tin compounds has been tested against the growth of bacteria in vitro to assess their bactericidal properties. While pentacoordinated compounds 1, 2, and 3 are described as moderate effective to noneffective drugs against both Gram-positive and Gram-negative bacteria, tetracoordinated tin(IV) compounds 4 and 5 are considered as moderate effective and most effective compounds, respectively, against the methicillin-resistant Staphylococcus aureus strains (Gram-positive)
