Published: September 2015

Para manterem-se competitivas as empresas otimizam seus processos continuamente, de maneira sustentável e reaproveitando os recursos naturais. As ferramentas de apoio a tomada de decisão são de extrema importância, principalmente quando tais ferramentas auxiliam na antecipação dos problemas operacionais, evitando custos, perdas de produtividade, acidentes de trabalho e ambientais. Este estudo tem foco no processo produtivo de alumina pelo método Bayer, na mensuração do teor cáustico da mistura de bauxita, que influencia diretamente na qualidade. A empresa obtém este resultado uma vez ao dia, por meio de análise laboratorial, devido aos elevados custos. A medida não é suficiente para tomada de decisão e antecipação das correções de problemas que possam evitar a ineficiência do processo, observado apenas no dia seguinte, quando ocorrer o recebimento do novo resultado. Propõe-se a previsão da concentração cáustica em tempo real, através da modelagem do processo por Regressão Linear Múltipla e Rede Neural Artificial. Tais modelos foram gerados através dos softwares SPSS e MATLAB. Os resultados foram comparados com base no erro entre a previsão da concentração do produto gerada pelos modelos, e a concentração real de saída obtidas de análise laboratorial. Concluiu-se que a técnica de Redes Neurais Artificiais desempenhou melhor que a Regressão Linear Múltipla. Os resultados mostraram a viabilidade do processo de análise imediata por meio da previsão, auxiliando assim a decisão da equipe de trabalho envolvida.
Von den operativen und erinnerungsgeschichtlichen Dimensionen eines Raumes. Die Schlacht von Tannenberg 1914 als Paradebeispiel räumlicher Inszenierung

Abstract
Tannenberg is still the cipher for a mythical memory space that interweaves German, Polish, Lithuanian and Russian sites of memory to each other, their temporal and political contexts, however, goes beyond. For the battle of 1914, the master narrative still follows the detailed descriptions of the Kriegsarchiv from the interwar period. These want to have found the key to success in the exemplary use of the geographic area by German generalship. Nevertheless, this battle has multidimensional perceptions, of the factual meaning of the space up to the imaginary. It is also an example of how clearly the topography of an area can determine the military capabilities, such as the importance of personal and mental connections to the competitive space. After the military occupation of East Prussia terrain the victorious commander Hindenburg conquered even the site of memory - with the Reichsehrenmal quite vividly. In the overall analysis of the Battle of Tannenberg therefore the access of the different concepts and dimensions of the room proves as purposeful and productive.

AbstractWe present a Bayesian method for characterizing the mating system of populations reproducing through a mixture of self-fertilization and random outcrossing. Our method uses patterns of genetic variation across the genome as a basis for inference about reproduction under pure hermaphroditism, gynodioecy, and a model developed to describe the self-fertilizing killifish Kryptolebias marmoratus. We extend the standard coalescence model to accommodate these mating systems, accounting explicitly for multilocus identity disequilibrium, inbreeding depression, and variation in fertility among mating types. We incorporate the Ewens sampling formula (ESF) under the infinite-alleles model of mutation to obtain a novel expression for the likelihood of mating system parameters. Our Markov chain Monte Carlo (MCMC) algorithm assigns locus-specific mutation rates, drawn from a common mutation rate distribution that is itself estimated from the data using a Dirichlet process prior model. Our sampler is designed to accommodate additional information, including observations pertaining to the sex ratio, the intensity of inbreeding depression, and other aspects of reproduction. It can provide joint posterior distributions for the population-wide proportion of uniparental individuals, locus-specific mutation rates, and the number of generations since the most recent outcrossing event for each sampled individual. Further, estimation of all basic parameters of a given model permits estimation of functions of those parameters, including the proportion of the gene pool contributed by each sex and relative effective numbers.

Authors: Kawai Alison Tse , Martin David , Kulldorff Martin , Li Lingling , Cole David V. , McMahill-Walraven Cheryl N. , Selvam Nandini , Selvan Mano S. , Lee Grace M. 
Published: September 2015

OBJECTIVES:
In the Post-Licensure Rapid Immunization Safety Monitoring Program, we examined risk of febrile seizures (FS) after trivalent inactivated influenza vaccine (TIV) and 13-valent pneumococcal conjugate vaccine (PCV13) during the 2010–2011 influenza season, adjusted for concomitant diphtheria tetanus acellular pertussis-containing vaccines (DTaP). Assuming children would receive both vaccines, we examined whether same-day TIV and PCV13 vaccination was associated with greater FS risk when compared with separate-day vaccination.

METHODS:
We used a self-controlled risk interval design, comparing the FS rate in a risk interval (0–1 days) versus control interval (14–20 days). Vaccinations were identified in claims and immunization registry data. FS were confirmed with medical records.

RESULTS:
No statistically significant TIV-FS associations were found in unadjusted or adjusted models (incidence rate ratio [IRR] adjusted for age, seasonality, and concomitant PCV13 and DTaP: 1.36, 95% confidence interval [CI] 0.78 to 2.39). Adjusted for age and seasonality, PCV13 was significantly associated with FS (IRR 1.74, 95% CI 1.06 to 2.86), but not when further adjusting for concomitant TIV and DTaP (IRR 1.61, 95% CI 0.91 to 2.82). Same-day TIV and PCV13 vaccination was not associated with excess risk of FS when compared with separate-day vaccination (1.08 fewer FS per 100 000 with same day administration, 95% CI −5.68 to 6.09).

CONCLUSIONS:
No statistically significant increased risk of FS was found for 2010–2011 TIV or PCV13, when adjusting for concomitant vaccines. Same-day TIV and PCV13 vaccination was not associated with more FS compared with separate-day vaccination.

Published: September 2015

OBJECTIVE:To determine whether subsequent births after short and long interpregnancy intervals (IPIs) are associated with risk of autism spectrum disorder (ASD).METHOD:We assessed the association between IPI and ASD risk in a cohort of 45 261 children born at Kaiser Permanente Northern California (KPNC) between 2000 and 2009. Children with ASD were identified from International Classification of Diseases, Revision 9 diagnostic codes 299.0, 299.8, and 299.9 recorded in KPNC electronic medical records. IPI was defined as the time from the birth of the first child to the conception of the second child. Survival analysis and logistic regression models were used to evaluate the association between IPI and risk of ASD in second-born children.RESULTS:Children born after an IPI of &lt;12 months or ≥72 months had a 2- to 3-fold increased ASD risk compared with children born after an interval of 36 to 47 months. Respective adjusted hazard ratios (95% confidence intervals) were as follows: &lt;6 months, 3.0 (1.9–4.7); 6 to 8 months, 2.1 (1.4–3.3); 9 to 11 months, 1.9 (1.3–2.1); 12 to 23 months, 1.5 (1.1–2.1); and ≥72 months, 2.4 (1.5–3.7). The results are not explained by maternal BMI or change in BMI between pregnancies or by parental age, maternal antidepressant medication use, or unfavorable events occurring during the first or second pregnancy.CONCLUSIONS:Children born after interpregnancy intervals &lt;2 years or &gt;6 years may be at increased risk of ASD. The mechanism explaining this association is unknown, and more research is needed.

OBJECTIVES:
To evaluate the generalizability of stringent protocol-driven weaning in improving total duration of opioid treatment and length of inpatient hospital stay after treatment of neonatal abstinence syndrome (NAS).

METHODS:
We conducted a retrospective cohort analysis of 981 infants who completed pharmacologic treatment of NAS with methadone or morphine from January 2012 through August 2014. Before July 2013, 3 of 6 neonatology provider groups (representing Ohio’s 6 children’s hospitals) directed NAS nursery care by using group-specific treatment protocols containing explicit weaning guidelines. In July 2013, a standardized weaning protocol was adopted by all 6 groups. Statistical analysis was performed to identify effects of adoption of the multicenter weaning protocol on total duration of opioid treatment and length of hospital stay at the protocol-adopting sites and at the sites with preexisting protocol-driven weaning.

RESULTS:
After adoption of the multicenter protocol, infants treated by the 3 groups previously without stringent weaning guidelines experienced shorter duration of opioid treatment (23.0 vs 34.0 days, P &lt; .001) and length of inpatient hospital stay (23.7 vs 31.6 days, P &lt; .001). Protocol-adopting sites also experienced a lower rate of adjunctive drug therapy (5% vs 21%, P = .004). Outcomes were sustained by the 3 groups who initially had specific weaning guidelines after multicenter adoption (duration of treatment = 17.0 days and length of hospital stay = 23.3 days).

CONCLUSIONS:
Adoption of a stringent weaning protocol resulted in improved NAS outcomes, demonstrating generalizability of the protocol-driven weaning approach. Opportunity remains for additional protocol refinement.

Soil fertility and disturbance interact to drive contrasting responses of co‐occurring native and nonnative species
Authors: Peltzer Duane A. , Kurokawa Hiroko , Wardle David A. 
Published: September 2015

AbstractSome plant functional groups such as nonnative invasive and nitrogen (N)‐fixing plants are widely thought to have consistent, coordinated differences in their functional traits relative to other groups such as native and non ‐N‐fixing plants. Recent evidence suggests that these trait differences between groups can be context dependent, varying with environmental factors such as resource availability and disturbance. However, many previous comparisons among plant groups differing in invasion status have not standardized growth form between groups or have compared species that do not co‐occur, which could result in invasion status per se being confounded with other factors. We determined growth and leaf functional trait responses of 20 co‐occurring woody species, that is, five species within each of four functional groups (native N‐fixers, native non ‐N‐fixers, nonnative [invasive] N‐fixers and nonnative [invasive] non‐N‐fixers), to factorial combinations of soil fertility and defoliation treatments in a mesocosm experiment to test each of two hypotheses. First, we hypothesized that nonnative invasive and N‐fixing species will have functional traits associated with rapid resource acquisition whereas natives and non ‐N‐fixing species will have traits linked to resource conservation. Second, we hypothesized that plant growth and leaf traits of nonnative and N‐fixing species will be more strongly influenced by environmental factors (i.e., soil fertility and disturbance) than will natives and non‐N‐fixers. Plant growth, foliar nutrients, and leaf structural traits varied among plant functional groups in a manner consistent with our first hypothesis. Support for our second hypothesis was mixed; origin (native vs. nonnative) and soil fertility rarely interacted to determine plant growth or variation in leaf traits whereas interactions involving N‐fixing ability and soil fertility were common. Further, there were no consistent interactive effects between plant groupings and disturbance. Our results demonstrate that variation in growth and functional traits among plant species were driven primarily by the relatively large responses of nonnative N‐fixers to soil fertility, rather than by consistent differences between other plant functional groups. These findings highlight the importance of resource availability in determining trait or performance differences among plant functional groups, and provide insights into the assembly of plant functional traits in novel communities of co‐occurring native and nonnative species.
Attentiveness to Community Needs and Corporate Social Responsibility in the Niger Delta Region
Authors: Obisike Ebere Ellison , Adalikwu-Obisike Justina 
Published: September 2015

Abstract
Given the fact that most literature on the activities of the Oil Multinational Corporations (MNCs) in Niger Delta region focuses on corporate inattentiveness to the needs of the communities and the chronic corporate and government socioeconomic irresponsibility, this study used Stakeholder theory and critical ethnography research method to examine the relationship between attentiveness to the needs of communities in the Niger Delta region and Corporate Social Responsibility (CSR).
While acknowledging that CSR has several definitions, we support McWilliams and Siegel (2001) 's assertion that CSR is the ability of a business corporation to go beyond legal and ethical compliance by engaging in business practices that seem to encourage some social good, above the interest of the corporation and that which is stipulated by law. The major aim of this paper was to offer practical solutions to the challenges facing natural gas development and exploitation in Nigeria. Data collected from five oil producing communities (Obagi, Obelle, Omoku, Ogbogu, and Obite) in Niger Delta between 2010 and 2013 were analyzed. The adoption of critical ethnography research method allowed these authors to objectively present their findings. This study concludes that only management practices, which support open and continuous dialogue with all the stakeholders and corporate socioeconomic policies that favour socio-cultural, environmental and economic concerns of all stakeholders will reap the full benefits of the Nigerian emerging economy.
Genetic Map and QTL Analysis of Agronomic Traits in a Diploid Potato Population using Single Nucleotide Polymorphism Markers

Published: September 2015

ABSTRACTGenetic maps now can be constructed using thousands of genomewide single nucleotide polymorphisms (SNPs) for identification of markers closely associated with agronomic traits. A diploid mapping population for potato (Solanum tuberosum L.) was developed from a pseudo‐testcross between a homozygous line S. tuberosum Group Phureja DM 1‐3 516 R44 and a heterozygous outcrossing S. tuberosum Group Tuberosum clone, RH89‐039‐16. The population of 96 individuals was evaluated for seven traits in two consecutive years (2012 and 2013). Yield (total tuber yield [TTY], average tuber weight [ATW], and number of tubers per plant [TS]), food quality (specific gravity [SPGR]), and plant development traits (vigor, maturity [Mat], and tuber end rot [TER]) were studied. Sixteen different quantitative trait loci (QTL) were identified. A QTL with major effects at 11.9 cM corresponding to 3.7 Mb on chromosome V of potato genome assembly explained between 20.3 and 75.7% of variance for TS, ATW, vigor, Mat, and TER. For TTY, ATW and SPGR, the QTL was detected at 6.4 and 12.9 cM. The other 15 QTL were located on chromosomes I, II, III, IV, V, VI, IX, X, and XII. In general, the results confirmed QTL previously identified for yield, SPGR, and Mat in diploid and tetraploid populations. The Infinium 8303 Potato Array provides an efficient means of scoring genomewide markers for constructing high‐resolution genetic maps and thereby facilitates identification of genomic regions closely associated with genes coding for agronomic traits of interest.
