From the Manifest Motive to the Real Demand of the Patient in the Psychological Consultation [Del motivo manifiesto a la demanda real del paciente en la consulta psicológica]
AbtractSometimes it is confusing to determine why you go to a psychological consultation; for the interviewer, it is extremely important to be clear about the manifest and latent motives, as well as the expectations of treatment with a psychoanalytic approach. It is a qualitative study, with a descriptive-explanatory design, which includes the analysis of semi-structured interviews. Twenty medical records of patients who attended the Centers for Psychological Intervention (CISP) in the state of Zacatecas, Mexico; in order to identify the manifest motive and latent motives, as well as treatment expectations and disease awareness. A relationship between these will be established, and their relevance of knowing them will be demonstrated so that later it can be used in an effective therapeutic process.ResumenEn ocasiones resulta confuso determinar por qué se acude a una consulta psicológica; para el entrevistador es de suma relevancia tener claros los motivos manifiestos y latentes, así como las expectativas del tratamiento con orientación psicoanalítica. Se trata de un estudio cualitativo, de diseño descriptivo-explicativo, el cual incluye el análisis de entrevistas semi-estructuradas. Se analizaron 20 historias clínicas de pacientes que acudieron a los Centros de Intervención Psicológica (CISP) en el estado de Zacatecas, México; con la finalidad de identificar el motivo manifiesto y los motivos latentes, así como las expectativas del tratamiento y la conciencia de enfermedad. Se establecerá una relación entre estos, y se demostrará su relevancia de conocer los mismos para que posteriormente se consiga emplear en un proceso terapéutico efica
The importance of context-dependent learning in negotiation agents
Automated negotiation between arti cial agents is essential to deploy Cognitive Computing and Internet of Things. The behavior of a negotiating agent depends signi cantly on the in uence of environmental conditions or contextual variables, since they affect not only a given agent preferences and strategies, but also those of other agents.
Despite this, the existing literature on automated negotiation is scarce about how to properly account for the effect of context-relevant variables in learning and evolving strategies. In this paper, a novel context-driven representation for automated negotiation is proposed. Also, a simple negotiating agent that queries available information from its environment, internally models contextual variables, and learns how to take advantage of this knowledge by playing against himself using reinforcement learning is proposed. Through a set of episodes against negotiating agents in the existing literature, it is shown that it makes no sense to negotiate without taking context-relevant variables into account. The context-aware negotiating agent has been implemented in the GENIUS negotiation environment, and results obtained are signi cant and revealing.Sociedad Argentina de Informática e Investigación Operativ

Biaixos atencionals en l’esquizofrènia: una revisió bibliogràfica
Antecedents: En la present revisió s’analitzen diverses investigacions
on s’estudien els biaixos atencionals en el processament de la informació
d’estímuls amb diferent valència emocional en persones amb esquizofrènia.
Metodologia: Bases de dades PubMed i PsycINFO, articles complets en anglés,
que utilitzen participants adults. L’objectiu és analitzar articles des de
l’any 2000 al 2016 on s’estudien els biaixos atencionals en l’esquizofrènia.
Pregunta de recerca: Existeixen biaixos atencionals en el processament de la
informació davant estímuls amb diferent valència emocional ‒càrrega emocional
agradable, desagradable o neutra‒ en persones amb esquizofrènia? Resultats:
22 articles, dels quals 7 d’ells utilitzen paraules com a estímuls i les
restants imatges. Els resultats mostren biaixos atencionals en el processament
d’estímuls emocionals. Conclusions: Alguns articles conclouen que hi ha un
biaix en el manteniment de l’atenció, on diversos autors afirmen que ocorre
en tots els estímuls emocionals, però altres asseveren que passa únicament
en estímuls amb valència negativa. D’altra banda, alguns autors manifesten
que el biaix atencional
ocorre en l’assignació automàtica de l’atenció cap
a imatges amenaçadores,
no en el manteniment. Finalment, pel que fa als
moviments oculars, els pacients tenen un menor nombre de fixacions però de més durada i, la seua trajectòria visual d’exploració, és més restringida que
en els participants control. Ressaltem la rellevància de la present investigació
pel que fa a la relació entre els problemes d’atenció observats i els dèficits en
habilitats socials de les persones amb esquizofrènia.Antecedents: In this paper will be shown some studies with schizophrenic
patients where are investigated the attentional biases in the information
processing of stimuli with different emotional valence. Method: Data base
PubMed and Psycinfo, full text in English where these papers only use adult
participants. The goal is analyse papers since year 2000 to 2016 where are
investigated the attentional biases in schizophrenia. Research question: Are
there any attention biases in the processing of information to stimuli with different emotional valences ‒pleasant, unpleasant or neutral emotional load‒
in people with schizophrenia? Results: 22 articles, 7 of these use words as
stimuli and the others use images. The results show attentional biases in the
processing of emotional stimuli. Conclusions: Some articles conclude that
there are biases in the maintenance of attention, where several authors agree
that they occur in all emotional stimuli, but others that are unique in stimuli
with negative valence. On the other hand, several authors show that attention
biases occurs in the automatic allocation of attention to threats, not in the
maintenance. Finally, eye movements show similar patterns between studies,
where patients showed brief but longer durations of fixations and, the visual
scan path is more restricted than control participants are. The results are
conclusive with the existence of biases in the processing of information from
stimuli with different emotional valence. We highlight the relevance of this
research in relation to the relationship between observed attention problems
and deficits in social skills of people with schizophrenia
Percepción familiar de la drogadicción en los jóvenes
Para conocer cómo perciben las familias la incidencia de la drogadicción en los jóvenes se realizó una investigación descriptiva con un enfoque cualitativo durante el II semestre del año 2016. Para dicha investigación se realizó un muestreo no probabilístico, el universo fueron las familias del Barrio el Centenario de la ciudad de Estelí, delimitando la muestra a 10 familias y tomando en cuenta 1 persona por familia de dicho Barrio. Se identificó la percepción que tiene cada familia del Barrio El Centenario de la ciudad de Estelí y de manera general, se concluyó que la comunicación entre padres e hijos es fundamental para evitar la drogadicción en la familia, además que el nivel económico y la cultura religiosa no es un factor de incidencia para que los jóvenes estén en riesgo de drogarse
Desempeño del expositor y mejores prácticas como factores de satisfacción de los asistentes a webinars
A raíz del distanciamiento social provocado por la COVID19, los eventos denominados como webinars han proliferado como una alternativa para distintas organizaciones en varios sectores; ya que sus características y beneficios que les confieren múltiples ventajas en comparación a las conferencias presenciales. Sin embargo, el estudio sobre los comportamientos de la audiencia en los webinars aún es incipiente. Por lo tanto, la finalidad de esta investigación fue la de identificar aquellos factores principales que inciden en la satisfacción del asistente a los webinars. La presente investigación se caracterizó por ser cuantitativa, de alcance exploratorio descriptivo, no experimental. Para la recolección de los datos, se optó por recurrir a una encuesta autoadministrada, con reactivos en escala de Likert, dispersada vía online a los alumnos de la Universidad del Noreste (UNE), en la Ciudad y Puerto de Tampico Tamaulipas. Después de obtenerse 380 observaciones validadas, se empleó un Análisis Factorial Exploratorio (AFE) con rotación VARIMAX. En conclusión, el presente estudio encuentra que el desempeño del expositor es un factor fundamental que incide en la satisfacción del asistente al webinar, destacando la efectividad para crear un espacio de aprendizaje cómodo y el entusiasmo empleado durante la exposición. Asimismo, las variables como: el diseño del curso, la organización y los aspectos técnicos; inciden en la satisfacción del asiste al webinar y pueden ser considerados como un solo factor ligado a la planeación del webinar; ya que las acciones que dimensionan a estas variables tienen similitud teórica con las mejores prácticas para webinars
Presentación inusual de un tumor de páncreas
The small instetine tumors are rare lesions that correspond to 2% of tumors of the gastrointestinal tract; presentation symptoms are nonspecific and may be similar to those caused by common diseases such as irritable intestine syndrome, intra-abdominal adhesions, etc. Among symptoms and the most common signs are abdominal pain intermittent colic, chronic diarrhea, iron deficiency anemia, intestinal obstruction, anorexia and weight loss, carcinoid syndrome, gastrointestinal bleeding of unknown location and abdominal mass. A man of 56 years with a small intestine tumor whose presentation symptom was an intercostal neuralgia is presented. The discovery of this tumor eventually open the way for diagnosing the only responsable of aberrant square: pancreatic adenocarcinoma.Los tumores del intestino delgado son lesiones raras que corresponden al 2% de los tumores del tracto gastrointestinal; los síntomas de presentación son inespecíficos y pueden ser similares a los causados por enfermedades tan comunes como el síndrome de intestino irritable, las adherencias intrabdominales, etc. Entre los síntomas y los signos más frecuentes están el dolor abdominal cólico intermitente, la diarrea crónica, la anemia ferropriva, la obstrucción intestinal, la anorexia y la pérdida de peso, el síndrome carcinoide, la hemorragia gastrointestinal de sitio desconocido y la masa abdominal. Se presenta un hombre de 56 años con un tumor de intestino delgado cuyo síntoma de presentación fue una neuralgia intercostal. El descubrimiento de este tumor abrió el camino para finalmente diagnosticar al único responsable del aberrante cuadro: el adenocarcinoma pancreático
Fibroblast response to initial attachment and proliferation on titanium and zirconium surfaces.
Introduction: In recent decades, dental implants have become one of the best options for comprehensive dental restoration; their placement is a multidisciplinary task that requires a solid understanding of biological, periodontal, surgical and prosthetic principles. Objective: The aim of this study was to quantify in vitro the adhesion and proliferation of human gingival fibroblasts’ (HGF) response on titanium (Ti) and zirconia (Zr) surfaces. Methodology: Samples of Ti and Zr were observed under atomic force microscopy (AFM). HGFs were inoculated in each sample to determine adhesion and cell proliferation. The MTT reagent was mixed with DMEM and inoculated in each plate; formazan was dissolved with dimethyl sulfoxide and analyzed at 540 nm in a microplate spectrophotometer. The test was performed with three independent experiments. Data were analyzed with Kolmogorov-Smirnov tests (Lilliefors), Kruskal-Wallis tests and Mann-Whitney test comparisons. Results: Topography of the Zr plates showed greater roughness (Ra= 0.39μm) than Ti (Ra= 0.049μm). Quantification of HGF adhesion was significantly higher (p˂0.05) in Ti, while proliferation showed no statistically significant differences between the groups. Conclusion: It is noteworthy that, even though Ti initially showed increased cell adhesion on the surface, after 24 h Zr samples showed similar proliferation; this demonstrates that both surfaces have a comparable biological response
