Testing Matching and Mirroring With Homophily in Onboarding Leadership Socialization

This study was designed to test the relationship between matching and mirroring (MM) and homophilous perceptions (PHM) in leadership socialization. Elevated PHM levels were hypothesized to affect workplace acceptance levels. The need for testing leadership socialization skills was magnified with the current demographic shift known as the leadership succession crisis, creating problems with onboarding strategies. The theoretical foundations of the study were based on the social identity theory, the social presence theory, the leader-member exchange theory, and the similarity-attraction paradigm. The study conducted at Workforce Solutions North Texas in Wichita Falls, Texas was sampled based on the calculated strength of the effect in a pilot study. Test group participants engaged in MM enhanced social conversation with a coached candidate and control group participants conversed with an uncoached participant from the general population engaging in normal conversation. MM processes were differentiated from natural synchronic tendencies using specialized software and Kinect-® sensors. A contrasted group, quasi-experiment was examined with an analysis of covariance. No statistically significant difference was found between groups on PHM levels, correcting for age, gender, ethnicity, height, glasses, hobbies, and professions. However, PHM and coworker acceptance were statistically significant but with no difference between groups. Further research is needed to test PHM as a metric for rapport in socialization strategies. Nevertheless, the homophily lens rather than the rapport lens can help organizational development and human resource professionals quantify and develop more effective socialization strategies aimed at solving problems associated with the leadership succession crisis

Tratamiento contable y fiscal que se le da a la comercialización de bienes y electrodomésticos bajo la figura del arrendamiento financiero, en la empresa Comercial Maritere S.A. de C.V. de la ciudad de Usulután

Un arrendamiento financiero, es aquel contrato mediante el cual el arrendador concede el uso y goce de determinados bienes muebles e inmuebles, con el propósito de realizar ventas en cierto periodo a futuro; la finalidad de este es transferir los riesgos al arrendatario y los cobros se realizaran a través de cuotas o cánones que son estipuladas en las cláusulas de un contrato. Tomando en cuenta el nivel de desarrollo de las grandes empresas y medianas que se dedican a la venta de bienes y electrodomésticos bajo la figura del arrendamiento financiero, en la actualidad, se debe dar gran importancia al desarrollo de una nueva forma de efectuar ventas a través del arrendamiento financiero con opción de compra, que es utilizado por las empresas comerciales. Establecer para el arrendador el tratamiento contable apropiado para el arrendamiento financiero para su adecuada presentación en los Estados Financieros es el objetivo general. Se utilizo el método explicativo por ser un método que reúne de otros métodos; lo que permite conducir la investigación a los resultados previstos. El estudio explicativo va mas allá de la descripción de conceptos o fenómenos, o del establecimiento de relaciones entre conceptos; están dirigidos a responder a las causas de los eventos físicos y sociales, así como los económicos. A demás se utiliza el método cuantitativo para el análisis numérico de los eventos económicos que se utilizaran en la investigación; porque se considera una herramienta muy importante dentro del desarrollo de la investigación, ya que por medio de este método se determinaran todas aquellas variables numéricas. En conclusión las empresas comerciales dedicadas a la comercialización de bienes muebles y electrodomésticos hacen de uso de sus propios recursos para invertir en los activos de la misma, lo cual representa un gran problema ya que la mayoría, no cuentan con los recursos financieros necesarios para obtener sus ingresos, haciendo del arrendamiento una fuente de financiamiento para la empresa; la cual genera los ingresos necesarios para las misma sin necesidad de recurrir a financiamientos comune

Starch Modified With Chitosan and Reinforced With Feather Keratin Materials Produced by Extrusion Process: An Alternative to Starch Polymers

They also reached up to 3800% and 3150% in maximum strength, respectively, compared to the matrix. The lysozyme test showed relevant changes in the degradability rate, because the weight loss of the films at 3 weeks decreased from 53% for starch-chitosan matrix and up to 34% for composites with 5wt% of modified quill. The results corroborated that chicken feather materials can be useful for the development of a manufacturing process for starch composites, and the decomposition of starch-chitosan composites can be controlled depending on the content and type of keratin.Starch (potato), chitosan, and feather keratin are used for processing biodegradable films produced by extrusion. The morphology of the films is examined with a scanning electron microscope and showed the excellent dispersion of keratin. The dispersion is the result of compatibility between the polysaccharides and proteins, as well as the proper operation of the extrusion process. Water solubility of the starch-chitosan films decreased with an increase of keratin materials. The storage modulus increased up to 137% for the composites with unmodified ground quill, and by 192% for composites with modified ground quill. In a tensile test, the composites with unmodified and modified quill reached outstanding increments up to 8160 and 7250% in elastic modulus, respectively, compared to the matrixUniversidad Autonoma del Estado de Mexico Tecnologico Nacional de Mexico Universidad Nacional Autonoma de Mexico Universidad Autonoma de Cd.

Observed and Expected Survival in Men and Women after Suffering a STEMI

Introduction: Mortality caused by ST elevation myocardial infarction (STEMI) has declined because of greater use of primary percutaneous coronary intervention (PCI). It is unknown if patients >75 have similar survival as peers. We aim to know it stratifying by sex and assessing how the sex may impact the survival. Methods: We retrospectively selected all patients >75 who suffered a STEMI treated with primary PCI at our institution. We compared their survival with that of the reference population (general population matched by age, sex, and geographical region). A Cox-regression analysis controlling for clinical factors was performed to know if sex was a risk factor. Results: Total of 450 patients were studied. Survival at 1, 3, and 5 years of follow-up for patients who survived the first 30 days was 91.22% (CI95% 87.80–93.72), 79.71% (CI95% 74.58–83.92), and 68.02% (CI95% 60.66–74.3), whereas in the reference population it was 93.11%, 79.10%, and 65.01%, respectively. Sex was not a risk factor, Hazard Ratio = 1.02 (CI95% 0.67-1.53; p = 0.92). Conclusions: Life expectancy of patients suffering a STEMI is nowadays intimately linked to survival in the first 30 days. After one year, the risk of death for both men and women seems similar to that of the general population

Frailty Assessment in a Cohort of Elderly Patients with Severe Symptomatic Aortic Stenosis: Insights from the FRailty Evaluation in Severe Aortic Stenosis (FRESAS) Registry

Background: Precise evaluation of the degree of frailty is a fundamental part of the global geriatric assessment that helps to avoid therapies that could be futile. Our main objective was to determine the prevalence of frailty in a specific consult of patients undergoing aortic valve replacement. Methods: From May 2018 to February 2020, all consecutive patients ≥75 years old, with severe symptomatic aortic stenosis, undergoing valve replacement in the Principality of Asturias (Northern Spain) were evaluated. Results: A total of 286 patients were assessed. The mean age was 84 ± 4.01 years old; 175 (61.2%) were female. The short performance physical battery score was 8.5 ± 2.4 and the prevalence of frailty was 19.6% (56 patients). In the multivariable analysis, age, Barthel index and atrial fibrillation were independent predictors of frailty. Conclusions: The prevalence of frailty in our sample patients undergoing aortic valve replacement, evaluated by a standardized protocol, was 19.6%
