Multidimensional Decision Making in Operations: An Experimental Investigation of Joint Pricing and Quantity Decisions
Authors: Ramachandran Karthik , Tereyağoğlu Necati , Xia Yusen 
Published: March 2018

Firms in several industries, such as medicine, apparel, and publishing, must jointly determine the price and production quantity of their products well in advance of the selling season. Normative prescriptions to solve this problem have generally ignored behavioral aspects of decision making while behavioral research has paid limited attention to interdependent, multidimensional decisions. We experimentally examine subjects’ performance when they jointly determine price and quantities. We find that subjects systematically deviate from the theoretically optimal price and quantity levels. Contrary to expectation, decomposing the price and quantity decisions does not improve subjects’ decisions. In a series of follow-up experiments, we isolate the effects of (a) interdependence between decisions and (b) demand uncertainty. We show that decisions improve by making subjects more aware of interdependence and by reducing the uncertainty. However, reducing complexity through partial automation of the interdependent dimensions does not improve the decisions made by subjects. We also find that subjects anchor on cost for price decisions and on mean demand potential for quantity decisions, thereby explaining the consistent underpricing and overordering behavior across experiments.

Published: March 2018

O milho é um dos cereais mais importantes cultivados no mundo, com o sistema plantio direto sendo a forma de plantio que mais cresce, usando-se semeadoras especiais com a finalidade de manter ou aumentar o conteúdo de matéria orgânica, além disso, são capazes de melhorar as qualidade físicas, químicas e biológicas do solo. Objetivou-se nesse trabalho avaliar o desenvolvimento e a produtividade do milho consorciado com feijão de porco para a implantação do sistema plantio direto na região do Cariri cearense, em Assaré-CE. O experimento foi desenvolvido em delineamento em blocos casualizados em esquema fatorial 3 x 2, com quatro repetições, totalizando 24 observações. O primeiro fator foram três níveis de adubação de fundação (0, 100 e 150%, sendo estas porcentagens em relação à dose recomendada), e o segundo fator foi referente à calagem (com e sem calcário). Os resultados permitiram concluir que a adição de adubo mineral a partir da dose ideal elevou os índices de desenvolvimento e produtividade da cultura do milho, com a calagem não apresentando resposta significativa em função do alto valor de saturação por bases inicial do solo.

Authors: Novaes Claudio 
Published: March 2018

Este ensaio traz algumas fotografias do nosso acervo pessoal que guarda registros da memória sertaneja. As fotos trazem algumas imagens de Capelas erguidas nas margens das rodovias e estradas, compondo um cenário lírico e dramático, como que expressa uma liturgia misteriosa e resistente da morte e vida na memória do sertão. São raras as rodovias que cortam o Nordeste brasileiro que não exibem capelas em suas margens, quase sempre erguidas em homenagens póstumas aos mortos por atropelos e outros incidentes perpetuados na memória pelas casinhas cravadas de cruzes.
MEMÓRIA ANCESTRAL e o Brasil contemporâneo – Tradição junguiana e o inconsciente brasileiro
Authors: Vrbata Ales 
Published: March 2018

Este artigo tem como seu ponto de partida algumas teses fundamentais da psicologia arquetípica, teses desonvolvidas por C. G. Jung e na virada dos anos 1960 e 1970 extensivamete desenvolvidas pelo James Hillman: 1) a imagem como manifestação primária e viva da psique e não como conceito teórico, 2) a necessidade do mito cultural vivo de cada comunidade humana, 3) aconsciência como titular das polaridades (oposições). Estas três teses podem servir como ponto de partida para a interpretação do encontro histórico da cultura europeia/portuguesa do século XVI e da cultura das tribos indígenas brasileiras e por isso também para a interpretação da cultura contemporâneabrasileira. São justamente essas teses que formam a base do pensamento do analista Roberto Gambini. Este estudo pretende apresentar o pensamento de Gambini sobre a identidade e a alma brasileira e referir-se as outras perspectivas junguianas abertas por conceito recente do “complexocultural” e como é aplicado nas condições brasileiras.

The aim of this study was to evaluate the performance of several Sorghum bicolor cultivars as forage on a dry land with pH of 5.4, N of 0.08%; C/N of 9%, P of 0.06% and K of 0.01%. Nine cultivars of S. bicolor (Super 1, Super 2, Numbu, Kawali, G2, G5, PAC 537, PAC 593 and PAC 501) were evaluated. Plot size was 16 m2 with space planting of 15 x 75 cm. The experimental design used was randomized block design with three replications. Parameters observed were plant height, time of flowering, forage production and quality. The result showed that the primary plant growth was not different in all cultivars. In the 65 days old primary plant, the Super 2, PAC 537 and Kawali had no flower yet. Biomass production varied in primary plant between cultivars of 11.35 - 26.17 kg/16 m2. The highest biomass production was obtained in PAC 537 of 26.17 kg/16 m2 (16.34 t/ha) which were significantly higher than G2 of 11.35 kg/16 m2 (7.09 ton/ha) and was not significantly different with other cultivars. In the 45 days ratoon I, Super 2, G5 and Super 1 showed faster growth. Biomass production increased in the ratoon I around 19.88 kg/16 m2 (12.42 ton/ha). PAC 537 produced the highest biomass of 30.14 kg/16 m2 (18.84 ton/ha) and was not significantly different with other cultivars, except with the G2. Biomass production of ratoon II decreased around 1.83 kg/16 m2 (1.14 t/ha)–4.77 kg/16 m2 (2.98 t/ha) and increased in the ratoon III of 15.72 kg/16 m2 (9.82 t/ha)–26.05 kg/16 m2 (16.28 t/ha). The quality of forage ratoon I was better compared to the primary plant with the lowest one was in ratoon II. It could be concluded that Super 1, Super 2 and PAC 537 cultivars might be recommended as potential forage.

Las instituciones públicas deben generar resultados eficaces y los Sistemas Integrados de Gestión se implementan como una herramienta administrativa que permite direccionarlas estratégicamente hacia sus objetivos. Sin embargo, en aquellas instituciones públicas que los han implementado, se presentan dificultades de tipo técnico, y peor aún, dificultades en el nivel laboral, al enfrentarse con situaciones controversiales en el ámbito del desarrollo de estos sistemas de gestión. De igual forma, la actualización de las normas técnicas internacionales ISO 9001 e ISO 14001 bajo la estructura de alto nivel, genera la necesidad de identificar las brechas existentes entre los sistemas implementados y los sistemas de gestión actualizados que sean herramientas reales, direccionadoras en la consecución de los objetivos estratégicos de la organización, herramientas que no discutan con la cultura organizacional impuesta y sean en cambio el agente dinamizador, que gestione la mejora al interior de la organización, aumentando la eficiencia, eficacia y ante todo efectividad visualizada en la sociedad. Este proyecto pretende dar las respuestas a las situaciones presentadas en una organización pública de Colombia, el Instituto Colombiano de Bienestar Familiar (ICBF) Regional Bogotá, institución donde se encuentra implementado un Sistema Integrado de Gestión bajo las pasadas versiones (NTC-ISO 9001:2008 y NTC-ISO 14001:2004) y SySO (NTC-OHSAS 18001:2007) omitiendo requisitos estipulados en las normas bajo las nuevas versiones, enfoques novedosos respecto de los beneficios que puede generar la implementación de un eficaz sistema de gestión que se desarrolle de forma integral al interior de la organización.
Adolescent Exposure to Toxic Volatile Organic Chemicals From E-Cigarettes
Authors: Rubinstein Mark L. , Delucchi Kevin , Benowitz Neal L. , Ramo Danielle E. 
Published: March 2018

BACKGROUND:
There is an urgent need to understand the safety of e-cigarettes with adolescents. We sought to identify the presence of chemical toxicants associated with e-cigarette use among adolescents.

METHODS:
Adolescent e-cigarette users (≥1 use within the past 30 days, ≥10 lifetime e-cigarette use episodes) were divided into e-cigarette–only users (no cigarettes in the past 30 days, urine 4-[methylnitrosamino]-1-[3-pyridyl]-1-butanol [NNAL] level &lt;1 pg/mL of creatinine; n = 67), dual users (use of cigarettes in the past 30 days in addition to e-cigarettes, NNAL level &gt;30 pg/mL; n = 16), and never-using controls (N = 20). Saliva was collected within 24 hours of the last e-cigarette use for analysis of cotinine and urine for analysis of NNAL and levels of 8 volatile organic chemical compounds. Bivariate analyses compared e-cigarette–only users with dual users, and regression analyses compared e-cigarette–only users with dual users and controls on levels of toxicants.

RESULTS:
The participants were 16.4 years old on average. Urine excretion of metabolites of benzene, ethylene oxide, acrylonitrile, acrolein, and acrylamide was significantly higher in dual users versus e-cigarette–only users (all P &lt; .05). Excretion of metabolites of acrylonitrile, acrolein, propylene oxide, acrylamide, and crotonaldehyde were significantly higher in e-cigarette–only users compared with controls (all P &lt; .05).

CONCLUSIONS:
Although e-cigarette vapor may be less hazardous than tobacco smoke, our findings can be used to challenge the idea that e-cigarette vapor is safe, because many of the volatile organic compounds we identified are carcinogenic. Messaging to teenagers should include warnings about the potential risk from toxic exposure to carcinogenic compounds generated by these products.

COSMIC Solver: A Tool for Functional Sizing of Java Business Applications
Authors: Tarhan Ayça , Sağ Muhammet Ali 
Published: March 2018

Functional Size
Measurement (FSM) provides a ground during software project life-cycle to
estimate planning parameters and track progress. Since it is time-consuming,
costly, and error-prone when functional size is measured manually, automating
the process of measurement has come to the fore. The literature includes
studies that automate FSM from software artifacts such as requirements
specifications, design models, and software code. In this study we focus on
automation of FSM from software code, and share our experience towards
developing a tool called ‘COSMIC Solver’ for COSMIC FSM of Java Business
Applications (JBAs). The tool automates the following steps: (i) Eliciting
textual representations of UML sequence diagrams from functional execution
traces of a JBA, (ii) tagging of these textual representations with the help of
AspectJ technology to measure COSMIC functional size, and (iii) calculating
functional size of user scenarios run in the JBA from the information on the
tags according to COSMIC FSM rules. In this paper we explain features and
measurement method of COSMIC Solver (v1.0), and the share results obtained from
functional sizing of an open source JBA by using the tool.&nbsp;
¿Qué información sobre los alumnos consideran relevante los docentes y qué implicación tiene sobre sus prácticas?
Authors: Cabrera Claudia 
Published: March 2018

Los profesores de enseñanza media reciben gran cantidad de información sobre sus alumnos, pero solo una parte de la misma es considerada a los efectos de la toma de decisiones. Los procesos que involucran la circulación de información traen consigo una selección y transformación de ésta, en concordancia con lo indicado por la "sabiduría práctica". Los docentes denominados líderes, especialmente valorados por sus colegas, manifiestan mayor capacidad de dar sentido a la información disponible. La identificación de los alumnos se ve favorecida cuando existen canales de comunicación fluidos, así como múltiples fuentes de información y espacios que permiten el intercambio entre los docentes. Los equipos de trabajo y su funcionamiento influyen sobre la construcción de teorías que elabora cada docente. Esas teorías incluyen a su vez opiniones y expectativas, y es sobre esta base que los docentes toman decisiones.

Underbalanced Drilling with Coiled Tubing: A Case Study in Marginal Shallow Wells
Authors: Miszewski Adam , Miszewski Toni , Hatgelakas Peter 
Published: March 2018

Abstract
This paper describes a recent Directional Coiled Tubing Drilling (DCTD) job that was completed for an independent operator in the Appalachian Basin. The objective was to access target zones identified adjacent to a recently drilled, vertical well using a lateral sidetrack. The target thickness was around 15ft so accurate depth control was critical. It was also considered essential that the entire reservoir section be drilled underbalanced to minimise formation damage.
The challenge was to deliver a productive horizontal sidetrack in an effective and cost-efficient manner. The field development strategy required costs to be kept to a minimum, but the use of high-tech equipment was essential to delivering the production improvements. A 3.2 inch DCTD Bottom Hole Assembly (BHA) and a specialised DCTD engineering software package were enabling technologies. A multi-disciplinary approach was adopted to plan and execute the sidetrack. This approach required inputs to the planning process from all stages in delivering the well, which included: 3D seismic, well trajectory planning, drilling engineering, completions.
This project was ultimately successful in that a dry hole was re-entered and sidetracked to create a productive well, thereby validating the technology and multi-disciplinary approach of the team. The lessons learned from this operation can be used to optimise the planning of future wells and maximise the value of re-entering marginal wells and fields.
