Resumo O monitoramento de longo prazo dos eventos de Influência do Buraco de Ozônio Antártico sobre o Sul do Brasil foi realizado no período de 35 anos entre 1979 e 2013 e calculada a climatologia e anomalias dos campos estratosféricos quando de sua ocorrência. Para isso, foram analisados os dados da coluna total de ozônio (CTO) obtidos através de Espectrofotômetros Brewer, instalados no Observatório Espacial do Sul - OES/CRS/INPE - MCTIC (29,4 °S; 53,8 °O; 488,7 m) e pelos instrumentos de satélite Total Ozone Mapping Spectrometer (TOMS) e Ozone Monitoring Instrument (OMI), além de parâmetros da reanálise II do NCEP/DOE (National Centers for Environmental Prediction/ Departament of Energy) e trajetórias retroativas do modelo HYSPLIT (HYbrid Single-Particle Lagrangian Integrated Trajectory). A metodologia empregada mostrou-se eficaz na identificação de 62 eventos com uma redução média de -9,35 ± 2,93% no conteúdo de ozônio. Além disso, foi realizada a identificação do padrão de circulação estratosférica através de campos médios e anomalias da vorticidade potencial, vento e temperatura para os dias de ocorrência do fenômeno, sendo observado um padrão de deslocamento de onda, embebida dentro de uma ampla região de circulação ciclônica, com ventos predominantemente de sul é advectado em direção ao Sul do Brasil.
Neurolinguistic late-side effects of childhood cancer treatment

The survival rate for children with brain cancer and tumours (CNS) has been going up in the last years. At the same time, different communicative, cognitive and psychological late-effects have been observed. These sequelae have a direct impact on the survivors’s academic performance, emotional state, social interaction, and the children’s quality of life in general. The objective of this paper is to focus on the communicative difficulties most commonly observed in children survivors of brain tumours treated at Virgen del Rocío Hospital in Seville (Spain):
An Empirical Study of the Impact of Management Standards on the Innovation Processes

PurposeThe aim of this research is to respond, from an empirical point of view, to the next question: “Does management systems based on standards hinder innovation processes? ”. MethodologyIn order to achieve this objective, an empirical work with the participation of 249 companies, in the framework of a research project called “Integrated Management Systems (IMS) in the Spanish companies” (SEJ2006-00682/ECON financed by the Ministry of Science and Technology within the aid program for R+D project) carried out from January to April 2006, is presented in this paper. FindingsPrincipal findings of the survey of 249 Spanish organizations registered to both the ISO 9001 and ISO 14001 standards which was illustrated here are: Managers and people involved in standardized management systems gave less importance to the statement that standards hinder innovation processes, although not with a statistically-significant difference compared to the other types of managers who responded to the survey. The importance given to the sentence “MSSs hinder innovation” decreased as more MSSs were considered for implementation in the future. Originality/valueThe majority of the work on innovation and quality management systems available in the current literature is based on the framework of Total Quality Management. In difference, the empirical analysis illustrated in this paper is focused on the various characteristics of standardized management systems, for example their current and future application and integration.
Power levels in office equipment: Measurements of new monitors and personal computers

Electronic office equipment has proliferated rapidly over the last twenty years and is projected to continue growing in the future. Efforts to reduce the growth in office equipment energy use have focused on power management to reduce power consumption of electronic devices when not being used for their primary purpose. The EPA ENERGY STAR[registered trademark] program has been instrumental in gaining widespread support for power management in office equipment, and accurate information about the energy used by office equipment in all power levels is important to improving program design and evaluation. This paper presents the results of a field study conducted during 2001 to measure the power levels of new monitors and personal computers. We measured off, on, and low-power levels in about 60 units manufactured since July 2000. The paper summarizes power data collected, explores differences within the sample (e.g., between CRT and LCD monitors), and discusses some issues that arise in m etering office equipment. We also present conclusions to help improve the success of future power management programs.Our findings include a trend among monitor manufacturers to provide a single very low low-power level, and the need to standardize methods for measuring monitor on power, to more accuratelymore » estimate the annual energy consumption of office equipment, as well as actual and potential energy savings from power management. « less
USABILITY EVALUATION OF A DESKTOP VIRTUAL REALITY PROTOTYPE (DVRP) COURSEWARE TO ENHANCE KNOWLEDGE ON DRUG ABUSE

Evaluation is a way to measure the usability of a computer-based system. Usability is the ability to carry out tasks effectively, efficiently and with satisfaction. Usability is the extent to which users can use a computer system to achieve specified goals effectively and efficiently while promoting feelings of satisfaction in a given context of use. It can be broadly defined as “ease of use”, and “usefulness”. This study aims to evaluate the usability, of the Desktop Virtual Reality Prototype (DVRP) courseware in enhancing knowledge on drug abuse among student teachers in a Teacher Education Institution. A total of 35 student-teachers were identified through simple random method to evaluate the usability of DVRP. In order to assess the usability of the DVRP courseware, the USE Questionnaire (Lund, 2001) was employed. USE stands for Usefulness, Satisfaction, and Ease of use. The results of this study on the usability show that the uses are very positive using the DVRP courseware and very effective and efficient to be used to enhance knowledge on drug abuse.
Distribution of stages and in vitro larval hatching in Globodera rostochiensis cysts.

Desgarennes, D. , G. Carrion, A. E. Nunez-Sanchez, and M. C. Nunez-Camargo. 2006. Distribution of stages and in vitro larval hatching in Globodera rostochiensis cysts. Nematropica 36:251-260. The classification of cysts as young (YC), mature (MC), and old (OC) on the basis of cyst wall color was shown to be a practical tool for the diagnosis of population status. Also important are differences in the stages that occur within cysts (eggs, J1, and J2), as they too are linked to differences in color. These data, from an ecological point of view, help us understand population structure. The density recorded for Los Pescados, Perote in the state of Veracruz, Mexico in one kilogram of soil was 2974 YC, 3004 MC, and 221 OC. On average, young cysts have 55-63% viable eggs, 37% of which contain a vitellus, without a developing embryo; MC have 38-54% viability, 39% of which are J1, with J2 also observed; in OC, 98% are empty eggs and have 2% viability with J1 and J2 juveniles. The greatest degree of hatching was observed in MC (19%), with juveniles hatching only four hours after being exposed to root exudates.
Prototyping as a powerful tool in a user centered innovation process

This short course aims to present prototyping techniques in the contexts of an user centered innovation process. Prototyping is a powerful tool to quickly communicate concepts, obtain feedback from end users and try ideas out. Thus, it has a key role in an innovation process. Apart from that, prototypes are a better option in comparison with more developed solutions due to the lower investment in time and money needed to create it, while still providing relevant information for the development cycle. Strongly based on practical activities, this short course will focus on how and with which purpose prototypes should be built. Additionally, participants will be invited to build various levels of prototypes (from paper to working prototypes) during the 8-hour course.
Development of Sublingual tablets of Bisoprolol Hemifumarate / Hydroxypropyl -β-Cyclodextrin Complex for Potential treatment of Angina Pectoris

Fast-disintegrating tablet drug delivery is gaining an importance for drug delivery technology especially for geriatric and pediatric patient because of swallowing difficulties. In certain diseases such as hypertension and angina pectoris therapy, taking a fast pharmacological response is of important criteria. Thus, the aim of the present work was to prepare a novel fast disintegrating Bisoprolol Hemifumarate (BH) tablet formulation for sublingual administration based on the use of 2-hydroxypropyl-βcyclodextrin (HP-βCD) which forms an inclusion complex with (BH) to improve the permeability of the drug to sublingual membrane, in addition to mask the taste of the drug through the inclusion complex. Attempt has been made to prepare fast disintegrating tablets of (BH) using superdistintegrants like crosscarmellose sodium and crospovidone in concentration of (5%). Eight different formulae (B1-B8) with variation in tablet excipients were prepared by direct compression method using different mucoadhesive polymers such as chitosan and polyethylene glycol 6000 at different concentration (3% and 6%) for reduction the flushing action of saliva and to provide enough contact time for drug to be absorbed. The tablets were evaluated for the weight variation, hardness, friability, wetting time, disintegration time and dissolution study. The formulae B2 and B7 possessed the lowest disintegration time due to the presence of the high concentration of chitosan, which has some disintegration action, thus were subjected to a pharmacokinetic study using human volunteers. The bioavailability of B2 was significantly higher than that of the reference (Concor®) (p > 0.05). Thus, the present investigations suggest that (BH) sublingual tablets allowed the rapid tablet disintegration, improved bioavailability and effective in emergency treatment of anginal pain and hypertension.
The Virtuous Circle of Corporate Social Performance and Corporate Social Disclosure

Previous literature in the field of corporate social responsibility investigates whether corporate social performance can be seen as a determinant of corporate social disclosure or, conversely, if corporate social disclosure is a determinant of corporate social performance. The aim of this paper is to join these two streams of research in a unique theoretical model, which can demonstrate that there is a mutual interaction between performance and disclosure. This can result, in the long run, in a virtuous circle where higher social performance generates future higher social disclosure and this determines higher future social performance and so on. An analytical model has been adopted to demonstrate the research hypothesis. Gathering data from the portfolios of the European Socially responsible funds (SRFs) listed on the Morningstar platform in 2010, the study analyzed 160 social reports published by 80 companies during 2008 and 2009. Findings, by demonstrating the non-one-way relationship between social performance and social disclosure, confirm the existence of a mutual influence between the results gained in different CSR areas and the capability to control and communicate such performance. In this way, the paper provides not only theoretical insights, but also practical implications for managers that are required to put in place responsive and effective initiatives towards the increasing pressure exerted by the internal and external environments in which they operate.
Input price discrimination with heterogenous sub-markets

The objective of the paper is to analyse optimal prices for an input monopolist in the presence of asymmetric information about the size of the submarkets, and when the sub-markets may provide either substitute or complementary products to the input provider’s own downstream subsidiary. The downstream firms produce products that may be vertically differentiated, but the degree of vertical differentiation is assumed to be private knowledge to the downstream firms.

Chronic effects of resistance exercise using reciprocal muscle actions on functional and proprioceptive performance of young individuals: randomized controlled trial

Studies have suggested that benefits from resistance exercise (RE) using antagonist muscle pre-activation could be transferred to functional activities. However, chronic studies using pre-activation through reciprocal actions in neuromuscular performance and functional activities are scarce. The aim of this study is to compare the effects of 12 RE sessions using reciprocal muscle actions and a traditional mode on functional and proprioceptive performance of young individuals. Forty eight young subjects were randomized into two groups: 1) reciprocal training (RT, 3 sets; 10 repetitions; knee flexion immediately followed by knee extension), 2) traditional training (TRA, 3 sets. 10 repetitions; knee extension). Pre and post evaluations were characterized by balance tests, hop tests (HT) and ”8” shape circuit (RC8). ANOVA 2X2 of mixed model was applied to analyze differences between pre and post-training conditions and between groups. For overall and anterior-posterior balance, no significant differences were found between RT and TRA (p>0.05). Similarly, no post-training differences were found. The medial lateral balance in the dominant limb showed no significant differences in post-training for both groups (p = 0.94), but the non-dominant limb showed significant differences between groups (p<0.01). In HT, significant post-training increases were found within groups (p<0.01), but no differences were found between them (p=0.90). RC8 was different between groups (p=0.03), indicating better post-training running time for TRA. Resistance exercise caused transfers to balance and functional performance, and training with reciprocal muscle actions showed better rates for HT and medial lateral knee balance.
Effects of Hybrid and Maturity on Maize Stover Ruminal Degradability in Cattle Fed Different Diets

The effect of maize hybrid (Suco and Dekalb 765, DK 765), maturity stage (milk, R3 and 1/2 milk line, R5) and animal diet (Diet 1: 70% lucerne hay+30% maize silage; Diet 2: 50% maize silage+20% sunflower meal+30% maize grain) on ruminal stover dry matter (DM) degradability was studied. Additionally, morphological and chemical plant composition was evaluated. Fodder samples ground at 2 mm were incubated in three Holstein steers (400 kg body weight) using the in situ technique. Ruminal degradation kinetics was studied and the effective degradability (ED) was estimated for an assumed kp of 5%/h. The in situ data was analyzed in a complete randomized block design with the animals as blocks. Significant interactions between hybrid×diet and maturity×diet on kinetic digestion parameters were detected. In Diet 1, hybrids did not differ in degradable fraction, kd or ED, although a minor difference (p<0.05) in the soluble fraction was found (25.5 and 23.2% for Suco and DK 765, respectively). In Diet 2, the DK 765 had greater degradable fraction (p<0.001) but smaller (p<0.01) kd than Suco, without differences in the soluble fraction or in ED. Anticipating the harvest increased ED of stover from 37.5% in R5 to 44.6% in R3 (average values across hybrids and diets) due to the increase (p<0.001) in the soluble fraction (R5: 22.6%, R3: 28.8%). It is concluded that hybrids had similar stover in situ DM degradability and that soluble fraction represent the main proportion of degradable substrates. Advancing the date of harvesting may not improve the in situ DM degradability of whole maize plant silage since the increase in stover quality is counteracted by the depression in the grain-to-stover ratio. The diet of the animal consuming silage might not improve stover utilization either. (Asian-Aust. J. Anim. Sci. 2003. Vol 16, No. 11 : 1619-1624)
Changing Job: A Real Option Analysis

Changing job is the strategy for a worker to maximize his earnings during the life time. To optimally implement this strategy, he has to spend an amount of searching costs, scans over the labor market, and eventually makes an optimal decision on when and at which searching costs he is willing to move his current job to a new one. Dominated by the traditional net present value approach, the existing literature suggests that a worker accepts a new job offer if the net potential earnings exceed the current earnings. However, this decision rule is not applicable if we consider the decision to change jobs as an option. So, the decision rule must be based on pricing this option. This paper concerns with developing a theoretical option based model of job changing, and validating this model with an empirical application. It came up with three main findings: (i) real option approach works well as modeling job changing decision; (ii) the optimal solution of the model sensitively responds to the changes in parameters; and (iii) the within industry mobility demands higher critical earnings gap the cross industry mobility does.

Boredom on Periscope and the number of Twitter followers: An exploratory study

Emotions expressed in the online social media have an impact on the size of an online social network. Boredom is an emotion that can prompt users of social media to be more active in engaging with their online social network. However, there has been little research to draw attention to the relationship between feelings of boredom and the size of the social media network. The focus of this paper is on the Periscope App users’ expressions of boredom, and their number of Twitter followers and the number of their friends. This study has found that bored English-speaking Periscope users have less Twitter followers compared with the English-speaking Periscope users who expressed ‘something else’ in the title of the livestreamed Periscope broadcast. This held true across three separate periods of time. Similarly, the study has found that having less Twitter followers is not related to expressions of boredom among Arabic-speaking Periscope users. Again this held true across three separate periods of time. On the other hand, while having less Twitter followers is related to expressions of boredom among English-speaking Periscope users but not among Arabicspeaking users, the two groups of users did not differ with respect to the number of Twitter friends in that expressions of ‘boredom’ in the title of the live-streamed Periscope broadcast was not associated with the number of Twitter friends; a finding that also held true across all the three periods.
THE COMPARISON BETWEEN SUPPOSITORY DICLOFENAC AND PETHIDINE IN POST-CESAREAN SECTION PAIN RELIEF: A RANDOMIZED CONTROLLED CLINICAL TRIAL

BACKGROUND: Narcotic drugs are usually used for postoperative pain control which could cause several complications such as respiratory depression and apnea. Therefore, replacement of these drugs with safer analgesics is recommended. The aim of this study was to compare the analgesic effects of suppository diclofenac and pethidine in post-cesarean section (C/S) patients. METHODS: In this clinical trial, pregnant women who were admitted to Alzahrah Hospital, Isfahan, Iran, between August and February 2004 and met the inclusion criteria were recruited. After obtaining informed consent, the patients were randomly assigned (block randomization) to two groups. In group A, 100 mg rectal suppository diclofenac was used after operation at four time points: at the end of operation and 8, 16 and 24 hours after the operation. Group B received pethidine 1 mg/kg intramuscularly at similar time points. The pain scores were assessed at 2, 10, 18 and 26 hours after C/S using the Visual Analogue Scale (VAS). Age, gestational age, parity, history of previous abortion, C/S and abdominal surgery, level of education, pain score, side effects and satisfaction level were assessed. Analysis was carried out with ANCOVA model and 8 2 Mantel Haenszel tests by SPSS.10 software. P 0.05). There was no significant difference between side effects in the two groups except for dizziness in 11 cases in group B. There were significant statistical difference between pain intensity in 10, 18 and 26 hours after C/S in group A and group B (2.05 ± 2.07, 1.4 ± 1.6 and 0.5 ± 1.1 vs. 2.6 ± 2.2, 2.3 ± 2.2 and 1.3 ± 1.9) respectively. CONCLUSIONS: The results of the present study showed that the use of suppository diclofenac is an appropriate replacement therapy for pain relief after C/S.
Survey on Interactive Visualization andNavigation of Web Search Results

It argues for making use of text structure when retrieving from full text documents and presents a visualization paradigm called Tile-Bars. The result lists of popular web search engines represent retrieved documents with a title a brief textual summary and a URL into the conventional search result interface. A set of guidelines for the design of exploratory search interfaces. An thoughtful of the impact of categorized overviews on search tactics will be useful to Web search developers. The image in our model is the solar system with its planets and asteroids revolving around the sun. Position, shade, effort, and three-dimensional distance of objects in the visual space are used to represent the semantic relationships between a query and relevant Web pages. It deals with a certain session of optimization methods, based on conservative convex separable approximations (CCSA), for solving inequality-constrained nonlinear programming problems.
