Purpose: This paper aims to examine whether a sample of non-financial Chilean firms performed earnings management to avoid the decreases and losses in the earnings during the 2010-2014 period. Design/methodology/approach: The analysis is undertaken using the distributions of earnings changes and earnings, according to Burgstahler and Dichev (1997) methodology. Findings: The results showed unusually low frequencies of small losses and small declines in earnings and unusually high frequencies of small benefits and small increases in earnings. Both results were statistically significant. Practical implications: The study presents evidence of possible earnings management activity to avoid reporting losses and earnings decreases during the period 2010-2014. These results would allow to identify “suspicious” companies of earnings management and would increase the likelihood of detecting fi...

Background: Case reports and case series are essential sources of knowledge; however, they only provide low-quality scientific evidence. These studies are common in the medical field because they allow to formulate new hypotheses and to report new and rare pathologies in a structured way and complications or adverse drug events. Hence, the primary objective of a case report or case series is contributing to the scientific knowledge. To publishing these studies, it is recommended to follow the CARE statement's recommendations to guarantee a structured report with a minimum of pertinent and relevant information to make a clear and precise interpretation of the findings. This review aims to provide a scientific writing guide for case reports and case series and maximize their publicity in indexed peer-reviewed journals.

One of the challenges of dentistry is oral rehabilitation in totally edentulous patients with atrophic jaws. This case reports a protocol for implant treatment performed in elderly patient with an edentulous jaws and advanced atrophy, in which an implant-retained implant-supported and consistent rehabilitation was conducted in a superior hybrid prosthesis supported by 6 implants and on lower denture retained by a horizontal bar attached to 4 implants, with a total follow-up of 1 year, without reporting complications. This case gives us evidence of an implant and rehabilitation protocol for patients with severe atrophy thus improving poor retention and stability posed by conventional prostheses in atrophic jaws, and show the benefits in terms of masticatory efficiency and better quality of life for patients with this diagnosis.

Heartworm disease is a parasitic infection with worldwide distribution, caused by the Dirofilaria immitis nematode and transmitted by culicid mosquitoes, with canines being the main hosts. Serologic tests provide some diagnostic help but are not conclusive. This report describes a clinical case of a canine in which the serological tests for filarial detection and the tests for the detection of microfilaraemia were inconclusive. However, the use of standardized protocols using ultrasound as part of the physical examination, evidenced the presence of cardiac filarials. The importance of reporting this case is to present a clinical protocol that includes cardiac ultrasound for an accurate diagnostic approach.

This thesis shows the existence of a problem in the analysis that judges do for granting of precautionary protection, specifically, when they evaluate the requirement called “plausibility of the right invoked” in each specific case. Evidence of this problem is drawn from various judicial decisions issued on the matter. Although the Peruvian legal system, local doctrine and judges according to their jurisprudence, share a conception of the fumus boni iuris and its importance as a requirement for granting of precautionary measures; in the reality, there is no uniform analysis methodology for this. This lack of uniformity produces negative effects on various fundamental rights that are developed in this work. Recognizing the existence of this problem, an analysis scheme of the “plausibility of the right invoked” is proposed that can contribute to the establishment of a general metho...

Se propone un algoritmo de computadora para la determinación automática del número de cifras significativas, para ser usado en el proceso de cálculo y presentación de resultados experimentales. Dicho algoritmo requiere el conocimiento de la incertidumbre estándar que afecta al resultado y puede ser implementado como una aplicación en diversos lenguajes de programación. El algoritmo propuesto es particularmente útil en los casos en que se deben reportar conjuntos grandes de resultados experimentales, que cubren un rango de varios órdenes de magnitud, como es por ejemplo el caso del análisis por activación neutrónica. Se presentan y discuten ejemplos de su aplicación, empleando una macro programada en MS EXCEL. Finalmente, se propone el criterio de reportar los resultados con una cola cifra incierta y sus incertidumbres asociadas con una sola cifra significativa, si los resul...
