Measuring Emotional Labor among Young Workers
Authors: de Castro Arnold B. , Curbow Barbara , Agnew Jacqueline , Haythornthwaite Jennifer A. , Fitzgerald Sheila T.
Published: July 2015

This analysis examines the applicability of the emotional labor scale from the Emotions at Work Scale (EWS) through the assessment of its psychometric properties in a sample of young workers. Factor analysis and test—retest reliability were conducted on a 13-item scale measuring emotional labor. The EWS 13-item emotional labor scale was refined to 9 items. Two subscales were delineated: 5 items measured surface acting and 4 items measured deep acting, each with a mean inter-item correlation of 0.33. Cronbach's alpha was .96 for the 9-item scale, and .71 and .67 for the surface acting and deep acting subscales, respectively. Test—retest reliability was 0.64 for surface acting and 0.51 for deep acting during a mean interval of 3 months. Emotional labor can be quantitatively measured among young workers using the derived 9-item scale, although additional studies further evaluating its use should be conducted.

Working Women and Contraception
Authors: Draper London
Published: July 2015

Contraception is not a new concept. Historically, various contraceptive methods and practices have been used throughout the world. Contraception is often a topic of great interest to working women because family planning helps them balance work and home more effectively. Occupational health nurses can play a vital role in supporting these women by providing education regarding health, contraception, and contraceptive choices.
Public Health Emergencies
Authors: O'Boyle Carol , Robertson Cheryl , Secor-Turner Molly
Published: July 2015

During a public health emergency such as an influenza pandemic or a bioterrorism attack, nurses may be at risk for exposure to lethal infectious diseases when caring for victims. The aim of this study was to identify interventions nurses believe will support their ability to cope during public health emergencies. A qualitative research design was used with 33 nurses from designated bioterrorism-receiving hospitals. Nurses recommended adequate protective equipment, education, drills, accessible information and available content experts, and available administrators. Other recommendations included increased security to protect nurses, emotional and physical support, communication with nurses' families, and commitment from institutions to care for ill or injured nurses. Preparations for emergencies should include assessments of nurses' and other stakeholders' concerns. These nurses proposed specific measures to improve safety, reduce anxiety, increase trust in hospitals, and provide physical and emotional support.
Zero Lift Programs in Small Rural Hospitals in Washington State
Authors: Charney William , Simmons Beverly , Lary Mike , Metz Suzanne
Published: July 2015

In Washington State, health care workers have the highest rate of compensable back injuries. Washington Hospital Services, a self-insured workers' compensation program, implemented a zero lift program in 31 of its 38 hospitals. Zero lift was defined as replacing manual lifting, transferring, and re-positioning of patients with mechanical lifting or use of other patient assist devices. This program included two trusts, two pools of hospitals that self-insure workers' compensation. The pools are governed by elected boards of trustees from the pool memberships and regulated by the State Department of Labor and Industries. This pretest–posttest descriptive study compared patient-handling injury data prior to program implementation with those after program implementation. Patient-handling injury claims decreased by 43% in the participating hospitals from 2000 to 2004 (i.e., from 3.51 to 2.23). The time lost frequency rate decreased by 50% (i.e., from 1.91 to 1.03).
Magnetic Resonance Imaging for Low Back Injuries
Authors: Eley Cecelia
Published: July 2015

Workers' compensation claims resulting from low back injuries are a major concern for U.S. employees and employers. Employees seek resolution of their injuries and related symptoms and rapid return to gainful employment. Employers are eager to help them, as they must absorb the health care and disability costs incurred. Health care providers involved with workers' compensation claims are charged with providing appropriate services to meet the needs of both employees and employers. Magnetic resonance imaging has become the gold standard for diagnosing low back injuries. This study provided data necessary for health care providers to design protocols using magnetic resonance imaging in managing workers' compensation claims for low back injuries.
Boron Workers in China
Authors: Chang Betty L. , Robbins Wendie A. , Wei Fusheng , Wu Guoping , Elashoff David A.
Published: July 2015

This article describes the lifestyle patterns of boron mining and processing workers ( N = 936) and a comparison group ( N = 251) in northeast China, and explores relationships between boron exposure and reproductive health. An English version of an interview guide addressing areas of work and lifestyle relevant to boron exposure and metabolism was developed by an occupational health research team, translated to Chinese, and translated back, for clarity. Modifications incorporated suggestions from a local community advisory board and boron industry workers; the translation–back translation process was reapplied, and cultural and semantic equivalence was attained. Results from the interviews showed more than 64% of workers and comparison group participants smoked tobacco and more than 92% reported exposure to environmental tobacco smoke. Boron workers and the comparison group varied in their food intake and alcohol consumption, but not in their smoking habits. Thirty-four percent of boron workers reported eating in the contaminated work area. Nearly all boron workers (99%) showered or bathed after work, although approximately 10% redressed in their contaminated clothes. Reproductive health outcomes were explored, including delayed pregnancy, multiple births, spontaneous miscarriages, induced abortions, stillbirths, and an unusual ratio of male to female offspring. Implications for occupational health nurses and recommendations for future research are provided.
Breast Cancer
Authors: Draper London
Published: July 2015

Breast cancer is the most common cancer and the second leading cause of cancer-related death for women in the United States (National Center for Chronic Disease Prevention and Health Promotion, 2006). Despite the plethora of readily available information, women die of this disease every day. Major strides have been made in early detection and treatment of breast cancer in recent years. However, more work remains. One in 8 (12%) U.S. women 90 years or younger will develop breast cancer sometime during her life (overall lifetime risk). Approximately 200,000 U.S. women and 1,500 U.S. men develop breast cancer each year. The three greatest risks for developing breast cancer are “female sex, increasing age, and family history of breast cancer” (Office of Genomics and Disease Prevention, 2006, p. 1).
Self-Paced Exercise Program for Office Workers
Authors: Low David , Gramlich Martha , Engram Barbara Wright
Published: July 2015

The impact of a self-paced exercise program on productivity and health outcomes of 32 adult workers in a large federal office complex was investigated during 3 months. Walking was the sole form of exercise. The first month, during which no walking occurred, was the control period. The second and third months were the experimental period. Participants were divided into three levels based on initial weight and self-determined walking distance goals. Productivity (using the Endicott Work Productivity Scale), walking distance (using a pedometer), and health outcomes (blood pressure, weight, pulse rate, and body fat percentage) were measured weekly. Results from this study, based on a paired t test analysis, suggest that although the self-paced exercise program had no impact on productivity, it lowered blood pressure and promoted weight loss. Further study using a larger sample and a controlled experimental design is recommended to provide conclusive evidence.
Combined Diet and Exercise Intervention in the Workplace
Authors: White Karen , Jacques Paul H.
Published: July 2015

This study assessed the effectiveness of a 12-week pilot employee wellness program in reducing risk factors for coronary heart disease. Fifty university employees with at least one cardiovascular disease risk factor participated in the program. Interventions focused on diet, exercise, and monthly workshops. Pre- and post-intervention measurements included weight, body composition, blood pressure, total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, total cholesterol/HDL cholesterol ratio, triglycerides, and blood sugar. Twenty-five employees had post-intervention measurements. A survey was administered to assess adherence. The correlation between adherence and improvement in cardiovascular disease risk factors was also tested. Significant differences were observed between pre- and post-intervention measurements of total cholesterol, LDL cholesterol, total cholesterol/HDL cholesterol ratio, triglycerides, and weight. A significant correlation existed between self-reported level of participation in the diet aspect of the program and improvement in LDL levels. This multi-component, 12-week pilot employee wellness program was effective in reducing cardiovascular disease risk.
Noise and Hearing Protection
Authors: Robertson Cheryl , Kerr Madeleine , Garcia Carolyn , Halterman Eve
Published: July 2015

This study explored Latino construction workers' experiences with occupational noise and hearing protection to provide qualitative data to be used in designing an intervention to prevent noise-induced hearing loss. An ecological framework provided the theoretical foundation for this study. Fifteen Latino construction workers participated in one of four focus groups exploring perceptions of exposure to noise on the job and barriers to and supports for wearing hearing protection. Support for an ecological framework was apparent in the environmental and personal factors revealed in the data: how it feels, personal responsibility, they make us wear it, we don't care about ears, it won't happen to me, being Latino, keeping our jobs, hearing protection is uncomfortable, and we can handle it. Researchers are applying results of this study in the development of a hearing conservation intervention for Latino construction workers to be evaluated in a randomized, controlled trial.

Heat-Related Illnesses
Authors: Rogers Bonnie , Stiehl Kristin , Borst Jennifer , Hess Andrea , Hutchins Shauna
Published: July 2015

Heat-related illnesses can occur in workplaces where hot environments pose a threat to at-risk workers. Operations involving high air temperatures and humidity, radiant heat sources, direct physical contact with hot objects, or strenuous physical activities have potential for inducing heat stress in employees engaged in job functions in specific industries. Exposure to high temperatures can lead to a progression of symptoms in the body, which can result in widespread tissue damage, organ damage, and even death if not treated in a timely and effective manner. Strategies to reduce the effects of heat in the workplace include engineering controls, administrative controls, and personal protective equipment. Occupational and environmental health nurses must be able to recognize and treat the broad range of symptoms that can result from exposure to high temperatures. They must work together with interdisciplinary teams to provide training and education to the work force so that workers are able to take appropriate measures to prevent the onset of a heat-related illness, recognize the early symptoms, and seek treatment. Interdisciplinary teams must ensure that appropriate controls in the work environment reduce the risk of heat exposure and related heat stress disorders. Education and early intervention are key to avoiding heat-induced illness and eliminating or minimizing the effects of high temperature environments.
Registered Nurses' Self-Nurturance and Life and Career Satisfaction
Authors: Nemcek Mary Ann
Published: July 2015

Knowledge of factors that help nurses thrive, including satisfaction with life and self-nurturance, can be used to enhance retention of a healthy work force. This study determined whether nurses are happy or satisfied with their lives; how self-nurturing or “good to self” they are; and whether a relationship exists among self-nurturance, life satisfaction, and career satisfaction. A descriptive, correlational study of 136 registered nurses involving measures of self-nurturance and life and career satisfaction was conducted. Mean scores for life satisfaction and self-nurturance were consistent with those from studies of well adults. Self-nurturance, life satisfaction, and career satisfaction were positively correlated with each other; thus, improving one is expected to improve the others. Knowledge of the significant positive correlation among life satisfaction, self-nurturance, and career satisfaction may prove useful in improving the mental health and safety of nurses. Strategies consistent with Magnet hospital characteristics are suggested for the occupational health nurse.
Hazardous Decibels

Published: July 2015

Noise-induced hearing loss ranks among the most significant occupational health problems. In the united states, more than 1 million firefighters are at risk for noise-induced hearing loss due to exposure to hazardous levels of intermittent noise from sirens, air horns, and engines of emergency vehicles and fire trucks. Although irreversible, noise-induced hearing loss is entirely preventable through both engineering controls and personal protective equipment. This article describes occupational noise exposure, hearing loss, and strategies to prevent noise-induced hearing loss among firefighters.

Injuries and Seasonal Risks among Young Workers in West Virginia—A 10-Year Retrospective Descriptive Analysis
Authors: Mujuru Priscah , Mutambudzi Miriam
Published: July 2015

This study used workers' compensation data to examine seasonal trends of compensable injuries among workers 14 to 24 years old during a 10-year period. These workers had higher rates of occupational injuries in major classes of industry (e.g., service, manufacturing, and agriculture) during summer and non-summer months. The overall rate of occupational injury was significantly higher for male workers than female workers in all age groups ( p & .001). Young workers experienced occupational injuries within less than 3 hours of starting a shift. Among males, injury rates were highest in the manufacturing industry for those 14 to 18 years old and in the service industry for those 22 to 24 years old for both seasons. These results indicate that preventing injuries among young workers should be a primary concern of education and health and safety professionals and parents.
Physical Activity Intervention in an Academic Setting Focus Group Results
Authors: Prosser Rachel A. , Thomas Anne C. , Darling-Fisher Cynthia S.
Published: July 2015

The purpose of this study was to elicit beliefs and attitudes about increasing physical activity in the workplace among staff and faculty in an academic setting as the first phase of a three-phase pilot study. Focus groups were conducted using the Theory of Planned Behavior as the basis for exploratory questions regarding workplace physical activity. The responses were tallied and themes emerged from the qualitative analysis. The primary themes indicated that physical activity at work would be beneficial because it could allow for more free time at home. However, it would not be advantageous if it took time away from work or conflicted with supervisors' needs. Differences in the likelihood of participation in a physical activity program were noted between staff and faculty. It was clear that successful design and implementation of the program needed the support of all employees in the school.

Long non-coding RNA ROR decoys gene-specific histone methylation to promote tumorigenesis
Authors: Fan Jiayan , Xing Yue , Wen Xuyang , Jia Renbin , Ni Hongyan , He Jie , Ding Xia , Pan Hui , Qian Guanxiang , Ge Shengfang , Hoffman Andrew R. , Zhang He , Fan Xianqun
Published: July 2015

Background

Long non-coding RNAs (lncRNAs) are not translated into proteins and were initially considered to be part of the ‘dark matter’ of the genome. Recently, it has been shown that lncRNAs play a role in the recruitment of chromatin modifying complexes and can influence gene expression. However, it is unknown if lncRNAs function in a similar way in cancer.

Results

Here, we show that the lncRNA ROR occupies and activates the TESC promoter by repelling the histone G9A methyltransferase and promoting the release of histone H3K9 methylation. Suppression of ROR in tumors results in silencing of TESC expression, and G9A-mediated histone H3K9 methylation in the TESC promoter is restored, which significantly reduces tumor growth and metastasis. Without ROR silencing, TESC knockdown presents consistent and significant reductions in tumor progression.

Conclusions

Our results reveal a novel mechanism by which ROR may serve as a decoy oncoRNA that blocks binding surfaces, preventing the recruitment of histone modifying enzymes, thereby specifying a new pattern of histone modifications that promote tumorigenesis.
Optimized threshold calculation for blanking nonlinearity at OFDM receivers based on impulsive noise estimation
Authors: Ali Zehra , Ayaz Ferheen , Park Chang-Soo
Published: July 2015

Impulsive noise (IN) degrades the performance of OFDM-based communication systems. Performance degradation is usually measured in terms of signal-to-noise ratio (SNR) and symbol-error rate (SER). To improve the performance of the system of OFDM receivers, one of the effective methods is to use blanking nonlinearity. In this method, the samples whose magnitudes exceed a certain fixed threshold are considered to be IN-affected and are therefore blanked. A fixed threshold does not always determine the IN-affected samples truly for all probabilities of IN occurrence. This paper proposes an optimized threshold-calculation method for blanking nonlinearity which is based on distribution characteristics of the received signal, i.e., mean, median, and peak. The proposed method can calculate an optimized threshold for all probabilities of impulsive noise occurrence. Simulation results show over 2.2-dB gain in SNR and lower SER by using the proposed method as compared to fixed threshold.
70-kDa heat shock cognate protein expression as a putative biomarker of heavy-metal burden in Mytilus galloprovincialis
Authors: Ratkaj Ivana , Žurga Paula , Bulog Aleksandar , Peter-Katalinić Jasna , Pavelić Sandra Kraljević
Published: July 2015

Background

Heavy metals naturally occur in the marine environment and ecosystems. Due to anthropogenic influence they became common waters and coastal regions pollutants in particular where their concentrations remain hazardously high. We therefore tested a protocol for combined analysis of 6 heavy metal (Pb, Cd, Cr, Zn, Fe and Hg) concentrations in mussels Mytilus galloprovincialis collected from a coastal industrial zone (shipyard locality) and mariculture facilities in combination with expression analysis of multi xenobiotic resistance related genes and stress-related gene (HSC-70).

Findings

In this paper we tested a protocol for heavy-metal levels assessment by use of a highly sensitive analytical method, ICP-OES, combined with expression analysis of multi xenobiotic resistance related genes, including the stress-related gene encoding 70-kDa heat shock cognate protein on mussels (Mytillus Galloprovincialis). Mussels from the shipyard locality had higher heavy metal concentrations, except Fe. Higher metal concentrations did not influence expression of multi xenobiotic resistance related genes with exception of stress-related gene (HSC-70) encoding 70-kDa heat shock cognate protein.

Conclusions

Our results indicate that mussels sampled in the industrial area have increased metal concentrations in comparison with the aquaculture locality, that are accompanied by increased transcript levels of HSC-70.

Authors: Kang Youngwoong , Choi Yong Keun , Kim Hyoung Joo , Song Younghan , Kim Hyungsup
Published: July 2015

In the study, we successfully produced electrospun cellulose fibers crosslinked with β-CD. For electrospinning, cellulose was dissolve in 1-ethyl-3-methylimidazolium acetate and DMF was added to the prepared solution for better spinnability. The prepared cellulose fiber was immersed in the solution containing β-CD, crosslinking agent and sodium hypophosphite. In order to understand the effect of a crosslinking agent, two different types of the agents, BTCA (1,2,3,4-butanetetracarboxylic acid) and citric acid with various concentrations were used for cross-linking. The crosslinking degree was increased with the concentration of the crosslinking agents, for the both agents. The cross-linked web changed into membrane like morphology when the concentration of the cross-linking agent was higher than 5 wt%. The concentration of crosslinking agent also gave influence on the crystallinity, the thermal property and the antibacterial activity of fibers. Due to the cross-linking the crystallinity was decreased. The cross-linked fiber showed selective bacterial behavior according to the bacterial strain and the cross-linking agent.
Retrocardiac lung hernia after thoracic esophagectomy: report of a rare case

Published: July 2015

A retrocardiac lung hernia is an extremely rare complication after esophagectomy. A 56-year-old man was admitted to our hospital with advanced middle thoracic esophageal cancer and a giant bulla at the apical portion of the right lung. Since it appeared that dissection of the upper mediastinum would most likely require resection of the right bulla, a two-stage operation for esophageal cancer was planned. During the first-stage operation, thoracic esophagectomy and resection of the right giant bulla were performed. Fourteen days after the first-stage operation, the patient underwent laparotomy as the second-stage operation to reconstruct a narrow gastric tube via a retrosternal route. After the second-stage operation, the inflammatory reaction was prolonged. Therefore, a thoracoabdominal computed tomography scan was performed, showing retrocardiac pulmonary atelectasis. The patient was diagnosed with a retrocardiac left lung hernia in which the left lower lobe was displaced into the right thoracic cavity. Because the inflammatory reaction was due to effects of the lung hernia, a repair operation was performed via a left seventh intercostal thoracotomy. At thoracotomy, the left basal segment of the lung was atelectatic and reddish and had herniated into the right thoracic cavity through an opening between the aorta and pericardium. The herniated lung tip adhered strongly to the subcarina, and synechiotomy was performed. We believe that simultaneous removal of the right giant bulla with esophagectomy was the important cause of this complication.
Sex Differences in Somatotrope Dependency on Leptin Receptors in Young Mice: Ablation of LEPR Causes Severe Growth Hormone Deficiency and Abdominal Obesity in Males
Authors: Allensworth-James Melody L. , Odle Angela , Haney Anessa , Childs Gwen
Published: July 2015

Leptin receptor (LEPR) signaling controls appetite and energy expenditure. Somatotrope-specific deletion of the LEPRb signaling isoform causes GH deficiency and obesity. The present study selectively ablated Lepr exon 1 in somatotropes, which removes the signal peptide, causing the loss of all isoforms of LEPR. Excision of Lepr exon 1 was restricted to the pituitary, and mutant somatotropes failed to respond to leptin. Young (2–3 mo) males showed a severe 84% reduction in serum GH levels and more than 60% reduction in immunolabeled GH cells compared with 41%–42% reductions in GH and GH cells in mutant females. Mutant males (35 d) and females (45 d) weighed less than controls and males had lower lean body mass. Image analysis of adipose tissue by magnetic resonance imaging showed that young males had a 2-fold increase in abdominal fat mass and increased adipose tissue density. Young females had only an overall increase in adipose tissue. Both males and females showed lower energy expenditure and higher respiratory quotient, indicating preferential carbohydrate burning. Young mutant males slept less and were more restless during the dark phase, whereas the opposite was true of females. The effects of a Cre-bearing sire on his non-Cre-recombinase bearing progeny are seen by increased respiratory quotient and reduced litter sizes. These studies elucidate clear sex differences in the extent to which somatotropes are dependent on all isoforms of LEPR. These results, which were not seen with the ablation of Lepr exon 17, highlight the severe consequences of ablation of LEPR in male somatotropes.
The Obesity-Linked Gene Nudt3 Drosophila Homolog Aps Is Associated With Insulin Signaling

Published: July 2015

Several genome-wide association studies have linked the Nudix hydrolase family member nucleoside diphosphate-linked moiety X motif 3 (NUDT3) to obesity. However, the manner of NUDT3 involvement in obesity is unknown, and NUDT3 expression, regulation, and signaling in the central nervous system has not been studied. We performed an extensive expression analysis in mice, as well as knocked down the Drosophila NUDT3 homolog Aps in the nervous system, to determine its effect on metabolism. Detailed in situ hybridization studies in the mouse brain revealed abundant Nudt3 mRNA and protein expression throughout the brain, including reward- and feeding-related regions of the hypothalamus and amygdala, whereas Nudt3 mRNA expression was significantly up-regulated in the hypothalamus and brainstem of food-deprived mice. Knocking down Aps in the Drosophila central nervous system, or a subset of median neurosecretory cells, known as the insulin-producing cells (IPCs), induces hyperinsulinemia-like phenotypes, including a decrease in circulating trehalose levels as well as significantly decreasing all carbohydrate levels under starvation conditions. Moreover, lowering Aps IPC expression leads to a decreased ability to recruit these lipids during starvation. Also, loss of neuronal Aps expression caused a starvation susceptibility phenotype while inducing hyperphagia. Finally, the loss of IPC Aps lowered the expression of Akh, Ilp6, and Ilp3, genes known to be inhibited by insulin signaling. These results point toward a role for this gene in the regulation of insulin signaling, which could explain the robust association with obesity in humans.
Measurement of Walking Noise on Floor Coverings
Authors: Scholl W. , Wittstock V. , Bietz H. , Stange-Kölling S.
Published: July 2015

Walking on floors in buildings generates noise in the room where the walking takes place. Manufacturers of floor coverings are interested in stating characteristic walking noise levels for their products. Recently, the European standard EN 16205 introduced such a measurement procedure. It is based on the former French standard NF S 31-074, but tries to solve the prevailing ‘self-noise’ problem of the walking noise source used (the ISO tapping machine) in a simpler and theoretically more correct way. To evaluate the EN method, a round-robin test with 17 European laboratories was carried out. The measurement methods of NF S 31-074 and EN 16205 and the round-robin test are presented here. It was found that EN 16205 works quite well with louder floorings like laminate and PVC. Soft and quiet floorings like carpets are more difficult to measure because their noise contribution disappears behind the noise of the ISO tapping machine.
Re-analysis of metagenomic sequences from acute flaccid myelitis patients reveals alternatives to enterovirus D68 infection
Authors: Breitwieser Florian P. , Pardo Carlos A. , Salzberg Steven L.
Published: July 2015

Metagenomic sequence data can be used to detect the presence of infectious viruses and bacteria, but normal microbial flora make this process challenging. We re-analyzed metagenomic RNA sequence data collected during a recent outbreak of acute flaccid myelitis (AFM), caused in some cases by infection with enterovirus D68. We found that among the patients whose symptoms were previously attributed to enterovirus D68, one patient had clear evidence of infection with Haemophilus influenzae, and a second patient had a severe Staphylococcus aureus infection caused by a methicillin-resistant strain. Neither of these bacteria were identified in the original study. These observations may have relevance in cases that present with flaccid paralysis because bacterial infections, co-infections or post-infection immune responses may trigger pathogenic processes that may present as poliomyelitis-like syndromes and may mimic AFM.  A separate finding was that large numbers of human sequences were present in each of the publicly released samples, although the original study reported that human sequences had been removed before deposition.

El “Laboratorio de leches preparadas” y la introducción de las leches albuminosas en España
Authors: Boatella Josep
Published: July 2015

Trabajo de tipo histórico en el que se relatan los inicios y posterior evolución de las leches albuminosas en España obtenidas, inicialmente, por el método propuesto por Finkelstein, en 1910. Se detallan las distintas modificaciones propuestas con los años, sus características y comentan las diferentes opiniones existentes en relación con la idoneidad e indicaciones del producto. Dentro de este contexto, se sitúa la figura de Joaquín Gómez Aguado, ilustre pediatra cordobés que, durante las primeras décadas del siglo XX, e independientemente de su actividad asistencial, realizó destacadas aportaciones en el ámbito de la dietética infantil. En calidad de verdadero inspirador y director técnico del “Laboratorio de leches preparadas”, se dedicó, en esta otra vertiente de su actividad profesional, a la preparación de diferentes alimentos-medicamentos de origen lácteo, a escala industrial. En este ámbito, destacó por el desarrollo de una leche albuminosa (“Lactobumosa”) pocos años después de la publicación de la propuesta de Finkelstein y para la que obtuvo un registro de patente de invención. Todo ello lo convierte también en pionero de la introducción de este tipo de derivados en nuestro país.
REPERCUSSÕES DO FUNDEF/FUNDEB NA REMUNERAÇÃO INICIAL DOS PROFESSORES DA REDE ESTADUAL DE ENSINO DO PARÁ
Authors: Carvalho Fabrício Aarão Freire
Published: July 2015

Este artigo teve por objetivo analisar as repercussões do FUNDEF/FUNDEB na remuneração inicial dos profissionais do magistério da rede estadual de ensino do Pará no período de 1996 a 2009. Configura-se como uma análise de políticas públicas, tendo como foco o exame das implicações da política de fundos para a efetivação da valorização docente no Estado. A pesquisa permitiu concluir que em termos de vencimento-base, os mesmos recebem valores abaixo do valor do piso salarial. A remuneração do professor no Estado é baixa, tanto em relação aos profissionais com ensino médio, quanto em relação às profissões de maior prestígio social com formação superior. No geral, estes professores, mesmo recebendo o abono FUNDEF/FUNDEB, não conseguiram equiparar sua remuneração com as destes profissionais.
Motivações Para a Internacionalização do Ensino Superior: Um Estudo de Casos Múltiplos em um Sistema de Ensino Superior Confessional Internacional
Authors: Muckenberger Everson , Miura Irene Kazumi
Published: July 2015

Uma das reações ou respostas das instituições de ensino superior (IES) à globalização tem sido a internacionalização. Há estudos sobre as motivações ou rationales que impulsionam IES públicas e particulares à internacionalização. Porém pouco se sabe sobre as motivações para a internacionalização entre IES confessionais e menos ainda sobre IES confessionais integrantes de sistemas de ensino superior internacionais. Para tanto, foi conduzido um estudo de casos múltiplos de seis IES, localizadas em diferentes regiões do mundo, mantidas por uma mesma  denominação religiosa e que, juntamente com outras IES, compõem um sistema de ensino superior confessional internacional, denominado de  Sistema Σ. As motivações identificadas confirmam parcialmente as rationales propostas por Knight (2004 e 2008), porém também foram identificadas motivações especificamente denominacionais. Quanto às motivações em nível de sistema, também se assemelham às motivações denominacionais.
A CRIANÇA DE SEIS ANOS NO ENSINO FUNDAMENTAL: PRODUÇÃO DO CONHECIMENTO EM TESES E DISSERTAÇÕES
Authors: Orlandi Leonardo Angelo , Lima José Milton
Published: July 2015

Esta pesquisa trata do ingresso da criança de seis anos no Ensino Fundamental e apresenta como objeto de estudo as produções acadêmicas entre os anos de 2006 e 2011. Estabelece como objetivo central: identificar nas produções dos programas de pós-graduação de Educação como o Ensino Fundamental de nove anos têm sido implementado em relação aos sujeitos escolares. O interesse em investigar tal tema adveio da constatação de que os descompassos decorrentes do ingresso das crianças de seis anos no primeiro ano do Ensino Fundamental estão gerando diversos paradoxos propícios para reflexões na forma de conceber a educação para a infância. A investigação de natureza qualitativa adotou como metodologia a pesquisa bibliográfica e analisou 42 dissertações e 4 teses localizadas em diferentes bancos de dados. Os resultados problematizaram que, diferentemente do que prescrevem os documentos oficiais, as mudanças foram ínfimas em relação ao currículo e às práticas destinadas as crianças de seis anos. http://dx.doi.org/10.14572/nuances.v26i0.2783
A CONSTRUÇÃO DO CONHECIMENTO CIENTÍFICO ATRAVÉS DAS INTERAÇÕES VERBAIS EM SALA DE AULA
Authors: Socha Rosana Ramos , Marin Fátima Aparecida Dias Gomes
Published: July 2015

O presente artigo é fruto de parte de uma dissertação de mestrado, em Educação, que teve por objetivo investigar as interações verbais entre professor e alunos, nas aulas de Física. Buscamos evidências de como essas interações podem contribuir para a construção do conhecimento dos alunos, e apresentamos elementos que visem à percepção, pelo professor, das interações que vivencia em sala de aula e sua relevância no processo de ensino-aprendizagem. Tratou-se de uma pesquisa qualitativa, em que os dados foram obtidos a partir de observações e gravações em áudio das aulas de Física de um professor com uma turma do segundo ano do Ensino Médio. Verificamos que o professor adota uma metodologia tradicional de ensino, que preza a apresentação de conteúdos e sua explicação, sem que os alunos tenham voz ativa sobre os temas abordados. Acreditamos que a realidade observada seja representativa de um universo maior. Isto significa que é necessário repensar o ensino de Física, com propósito de realizar intervenções que qualifiquem o processo de ensinar e aprender. http://dx.doi.org/10.14572/nuances.v26i0.2807
TRABALHO INFANTIL SOB DIFERENTES OLHARES: REPRESENTAÇÕES SOCIAIS DE FAMÍLIAS E PROFISSIONAIS DA EDUCAÇÃO
Authors: Mantovani Aline Madia , Coimbra Libório Renata Maria
Published: July 2015

O trabalho infantil é um fenômeno que tem ocorrido em nossa sociedade desde os primórdios e se intensificou após a Revolução Industrial, tanto em situações domésticas e informais como na agricultura. Tendo em vista seu caráter social, econômico e cultural este estudo tem por objetivo traçar alguns apontamentos acerca do trabalho infantil a partir das representações sociais compartilhadas por famílias e profissionais da educação de duas escolas públicas estaduais de Presidente Prudente/SP. Tal problemática faz parte de uma pesquisa maior de abordagem qualitativa que adotou como instrumentos de coleta de dados o questionário e a entrevista, juntamente com câmeras fotográficas. O recorte apresentado nesse estudo remete-se aos dados obtidos por meio dos questionários e tem como referencial teórico a Teoria das Representações Sociais. De acordo com os participantes, o trabalho infantil é revestido de inúmeras definições, ora positivas ora negativas, que influenciam o imaginário social e contribuem para a construção de situações tidas como protetoras e uteis ao desenvolvimento e/ou dotadas de prejuízos para quem a exerce. http://dx.doi.org/10.14572/nuances.v26i0.2811

Social network analysis of e-complaints in fast food sectors in Turkey
Authors: Yüncü Deniz , Yüncü Hilmi Rafet
Published: July 2015

Complaint is defined as an act of reflecting a dissatisfying situation to other side. Consumers act differently while they are expressing their dissatisfaction. Consumer complaints constitute an important feedback mechanism for companies. Thanks to these feedbacks, the firms get a chance to correct the mistake in the process of production and to produce a more satisfying product. Consumers express their complaints about the dissatisfying processes through feedback to the firm, expressing them to their friends, or resentment. With the developments in the Internet technology, it is seen that complaints have become widespread. Consumers let more people know about their complaints by expressing them in the internet environment. Therefore, the firms should attach importance to e-complaints and tolerate the dissatisfaction of their consumers. Although there are some studies about consumer complaints in the tourism area, there are not any studies about fast-food agencies. For this reason, it is aimed to categorize the fast-food agencies in www.sikayetvar.com.

Published: July 2015

Milk leakage from the breast, which is known as galactorrhea, can be caused by a number of pharmacological, physical, and tumoral factors. Galactorrhea is a well-known side effect of domperidone, and is usually associated with hyperprolactinemia. However, euprolactinemic galactorrhea secondary to domperidone is very rarely seen and has yet to be reported in children before. Here, we report an adolescent with euprolactinemic galactorrhea caused by domperidone.
