Analysis of Experimental Cross-Sections of Charge Exchange between Hydrogen Atoms and Protons Yields More Evidence of the Existence of the Second Flavor of Hydrogen Atoms

Measurements of cross-sections of charge exchange between hydrogen atoms and low energy protons (down to the energy ~10 eV) revealed a noticeable discrepancy with previous theories. The experimental cross-sections were systematically slightly higher—beyond the error margins—than the theoretical predictions. In the present paper, we study whether this discrepancy can be eliminated or at least reduced by using the Second Flavor of Hydrogen Atoms (SFHA) in calculations. We show that for the SFHA, the corresponding cross-section is noticeably larger than for the usual hydrogen atoms. We demonstrate that the allowance for the SFHA does bring the theoretical cross-sections in a noticeably better agreement with the corresponding experiments within the experimental error margins. This seems to constitute yet another evidence from atomic experiments that the SFHA is present within the mixture of hydrogen atoms. In combination with the first corresponding piece of evidence from the analysis of atomic experiments (concerning the distribution of the linear momentum in the ground state of hydrogen atoms), as well as with the astrophysical evidence from two different kinds of observations (the anomalous absorption of the redshifted 21 cm radio line from the early universe and the smoother distribution of dark matter than that predicted by the standard cosmology), the results of the present paper reinforce the status of the SFHA as the candidate for dark matter, or at least for a part of it.

autoestima en el accountability para la toma de decisiones

El objetivo del presente estudio de caso es determinar si la autoestima es un factor que influye en el accountability para la toma de decisiones asertivas. Es un estudio no experimental, transversal, mixto, fenomenológico y descriptivo. Los instrumentos son: cuestionario para toma de decisiones, y accountability, prueba psicométrica y grupo focal. Los resultados muestran que los sujetos tienen las habilidades para la toma de decisiones, sin embargo su falta de seguridad y sus creencias limitantes no les permiten ser asertivos. La propuesta es incluir en el perfil de puesto el nivel de toma de decisiones y de seguridad para decidir e implementar capacitación en accountability. Abstract The objective of this study is to determine if self-esteem is a factor which influences accountability when assertive decisions are made. This is a non-experimental, cross-sectional, mixed, phenomenological, and descriptive study. The instruments are, a questionnaire for decision-making and accountability, a psychometric test, and a focus group. Results show that the subjects have the ability of decision-making, nevertheless, the lack of confidence and limiting beliefs do not allow them to be assertive. We propose to include in the job profile, the level of decision-making, and confidence in deciding, together, with the implementation of accountability training.

Aceptación de mitos sobre agresión sexual en universitarios colombianos=Acceptance of myths about sexual agression among Colombian university students

<p><strong>Resumen</strong></p><p>La presente investigación estudia la relación entre la aceptación de mitos sobre la agresión sexual en estudiantes de una universidad colombiana. Es un estudio de alcance correlacional con un diseño no experimental transversal en el que participaron 176 estudiantes, escogidos por medio de un muestreo no probabilístico por conveniencia. Se aplicó, de manera presencial y virtual, el instrumento <em>Acceptance of Modern Myths about Sexual Aggression</em> (AMMSA) en su adaptación al español. Se concluyó que existen diferencias significativas entre las variables sexo y facultad con los resultados en la prueba, siendo los hombres e ingenieros quienes mostraron una mayor normalización de situaciones sexualmente violentas.</p><p><strong>Abstract</strong></p><p>The following investigation studies the relationship between the acceptance of myths about sexual aggression among students at a Colombian university. The study has a correlation scope with a non-experimental cross-sectional group comparison design, in which 178 students were involved. The Acceptance of Modern Myths about Sexual Aggression scale (AMMSA), adapted into Spanish, was applied directly and virtually. As a result, this study has demonstrated the significant differences between the sex and faculty variables and the results of the test, in which the males and engineers showed a greater normalization of sexually violent situations.</p>

Management of the budget by results and National Urban Sanitation Program in local governments, Lima 2015

This research aims to determine the relationship that exists between the budget for results and the National Urban Sanitation Program in local governments, Lima 2015. The study is of the applied type, of correlational level, of non-experimental, cross-sectional design, whit a methodology was hypothetical-deductive framed in the statement of the hypothesis that is later contrasted. It is concluded that there are indications to affirm that budget management by results has a moderate and positive relationship (R=0.616**), as well as significant (p <0.05).
