How financial liberalization in Indonesia affected firms'capital structure and investment decisions
How did financial liberalization affect Indonesian firms? The authors analyzed real and financial indicators for the establishments in their panel of Indonesian manufacturing establishments for 1981-88. Their sample was not representative, but their evidence shows that economic reform had favorable effect on the performance of smaller firms. Liberalization helped reallocate domestic credit toward smaller firms to a level roughly proportionate to their contribution to value-added. Moreover, other firms were successful in replacing expensive domestic credit with cheaper foreign credit, releasing some domestic credit to establishments that lacked access to it. Nominal and real interest rates rose to very high levels, but real returns to capital assets remain high and have increased substantially for small and medium-size exporting establishments. For all groups, higher rates of financial leverage gave rise to extremely high returns on owned equity. Medium-size firms - both conglomerate and non-conglomerate - have had the highest rates of return to capital, financial leverage, and returns to equity. Financial reform has had a significant impact on firm's real and financial choices. Shifting from administrative allocations of credit to market-based allocations has increased borrowing costs, particularly for smaller firms, but it has also widened access to finance. The net effect appears to have been a decrease in the degree of market segmentation and a relaxation of financial constraints to the benefit of investment activity.Banks&Banking Reform,Environmental Economics&Policies,Financial Intermediation,Economic Theory&Research,Financial Crisis Management&Restructuring
Simulation-Based Data Augmentation for the Quality Inspection of Structural Adhesive with Deep Learning
UIDB/00066/2020 POCI-01-0247-FEDER-034072The advent of Industry 4.0 has shown the tremendous transformative potential of combining artificial intelligence, cyber-physical systems and Internet of Things concepts in industrial settings. Despite this, data availability is still a major roadblock for the successful adoption of data-driven solutions, particularly concerning deep learning approaches in manufacturing. Specifically in the quality control domain, annotated defect data can often be costly, time-consuming and inefficient to obtain, potentially compromising the viability of deep learning approaches due to data scarcity. In this context, we propose a novel method for generating annotated synthetic training data for automated quality inspections of structural adhesive applications, validated in an industrial cell for automotive parts. Our approach greatly reduces the cost of training deep learning models for this task, while simultaneously improving their performance in a scarce manufacturing data context with imbalanced training sets by 3.1% ([email protected]).

Administrative And Clinical Denials By A Large Dental Insurance Provider
The objective of this study was to assess the prevalence and the type of claim denials (administrative, clinical or both) made by a large dental insurance plan. This was a cross-sectional, observational study, which retrospectively collected data from the claims and denial reports of a dental insurance company. The sample consisted of the payment claims submitted by network dentists, based on their procedure reports, reviewed in the third trimester of 2012. The denials were classified and grouped into 'administrative', 'clinical' or 'both'. The data were tabulated and submitted to uni- and bivariate analyses. The confidence intervals were 95% and the level of significance was set at 5%. The overall frequency of denials was 8.2% of the total number of procedures performed. The frequency of administrative denials was 72.88%, whereas that of technical denials was 25.95% and that of both, 1.17% (p < 0.05). It was concluded that the overall prevalence of denials in the studied sample was low. Administrative denials were the most prevalent. This type of denial could be reduced if all dental insurance providers had unified clinical and administrative protocols, and if dentists submitted all of the required documentation in accordance with these protocols.29
Radiopacity evaluation of Portland and MTA-based cements by digital radiographic system
OBJECTIVE: The aim of the present study was to evaluate the radiopacity of Portland and MTA-based cements using the Digora TM digital radiographic system. MATERIAL AND METHODS: The performed tests followed specification number 57 from the American National Standard Institute/American Dental Association (2000) for endodontic sealing materials. The materials were placed in 5 acrylic plates, especially designed for this experiment, along with a graduated aluminum stepwedge varying from 1 to 10 mm in thickness. The set was radiographed at a 30 cm focus-object distance and with 0.2 s exposure time. After the radiographs were taken, the optical laser readings of radiographs were performed by Digora TM system. Five radiographic density readings were performed for each studied material and for each step of the aluminum scale. RESULTS: White ProRoot MTA (155.99±8.04), gray ProRoot MTA (155.96±16.30) and MTA BIO (143.13±16.94) presented higher radiopacity values (
Síntese e caracterização de compostos de coordenação do íon croconato com metais da primeira série de transição
Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências Físicas e Matemáticas. Programa de Pós-Graduação em QuímicaO croconato é conhecido por ser um membro da família oxocarbônica, que são moléculas cíclicas e planares de fórmula geral CnOn2-. O croconato (C5O52-) por ser um pentágono regular, pode assumir diversos modos de coordenação. Com os metais bivalentes da primeira série de transição o croconato forma uma série polimérica e isoestrutural. O monômero deste polímero consiste no croconato quelado nas carbonilas das posições 1 e 2, e monocomplexado na posição 4. Foram determinadas as constantes de formação dos compostos MCR (onde M= Mn(II), Fe(II), Co(II), Ni(II), Cu(II) e Zn(II).) bem como os respectivos equilíbrios químicos. Também foi realizado um estudo eletroquímico destas espécies, observou-se uma certa relação entres as constantes de formação obtidas com as mudanças nas propriedades eletroquímicas do ânion croconato descomplexado. O estudo de complexos de metais trivalentes como os de Fe(III), Cr(III) e Al(III), foi realizado com o intuito de encontrar a descrição das estruturas moleculares e eletrônicas destes. O Fe(III) é formado em uma primeira etapa de complexação, que é seguida pela decomposição do complexo. Esta também é acompanhada da redução do Fe(III). O precipitando é uma mistura de Fe(II)CR com Fe(II)(ânion radical croconato). A análise dos compostos de Al(III) e Cr(III) mostrou indícios de estruturas moleculares com o croconato complexado ao metal hidrolisado
Políticas de lugar en Morococha : el contexto del reasentamiento por el proyecto minero Toromocho
La investigación busca responder a la cuestión de la construcción del sentido de lugar en sociedades sujetas a procesos de reasentamiento involuntario. Los objetivos son analizar los discursos y prácticas concretas que hacen posible la construcción de un espacio ajeno como "propio". Durante el trabajo de campo se buscó identificar narrativas culturales sobre la ciudad de Morococha, destruida lentamente en un largo y extenuante conflicto de baja intensidad con la empresa minera Chinalco; así como de la nueva ciudad construida como reemplazo del lugar perdido. Al medio de estas dos narrativas se encuentra un complicado un largo proceso de negociación entre la minera, las organizaciones sociales y los trabajadores de las diferentes empresas que operan en el distrito. Asimismo, se analizan prácticas cotidianas y rituales como la conmemoración de fechas importantes y fiestas religiosas que median el "acostumbramiento" de la gente a la nueva ciudad. A lo largo del siglo XX se dio en Morococha un proceso de nucleación urbana basada en la concentración de campamentos mineros de diversas empresas. Los descendientes de los trabajadores atraídos por el empleo en los socavones se asentaron, algunos reproduciendo la mano de obra minera y otros diversificando sus ingresos dedicándose al comercio y a servicios. Este modelo de ciudad-campamento dio lugar a interacciones particulares entre la fuerza de trabajo y la administración, posicionando al distrito como uno de los centros del movimiento obrero en el Perú. Las crisis inherentes al ciclo económico de los minerales y la proliferación de las services a fines de siglo dieron lugar a una desestructuración de los campamentos y al progresivo despoblamiento de la de la ciudad. El reasentamiento actual responde a nuevas necesidades materiales de organización de la mano de obra y a discursos de Responsabilidad Social de la industria extractiva.Tesi
