title: Influence of different crops and climate factors on the occurrence of green lacewings in agroecological system

description: The green lacewings (Chrysopidae) have been reported in natural ecosystems as well in agroecosystems, intercropping or monocropping. However, the knowledge on their behavior on different agroecosystems is scarce. The present work aimed to determine the diversity of green lacewing species and to evaluate the influence of different agricultural crops, as well as climate factors, on the abundance of these insects in an agroecologically-based organic production system. The study was conducted from September 2008 to August 2009, by performing weekly sampling of Chrysopidae adults in areas of the Integrated Production Agroecological System (SIPA) in Seropédica (RJ), each with one type of cropping system (corn-mucuna rotation/vegetable crops; shaded coffees and sugar cane/brachiaria pasture rotation). A total of 424 adult specimens were collected, belonging to three species: Chrysoperla externa (98.1%), Ceraeochrysa cubana (1.7%) and Ceraeochrysa paraguaria (0.2%). There were no differences on the number of green lacewing adults collected in the crops, although the correlation analysis showed that the crop rotations with grasses favor their abundance. The abundance of green lacewings was also influenced by the climate conditions only in the system of shaded coffees, being negatively correlated with mean air temperature and accumulated rainfall.

title: Costing Methods: meta-analysis of articles presented in the Brazilian Congress of Costs over the 1994-2010 period

description: ABSTRACT There are many bibliometrics studies that refer to costing methods. However, this research is scattered over the analyzed period, the place of publication and the publishing of the studies analyzed, as well as the longitudinal cut established, amongst other methodological design issues. The goal of this study is to compile and complement bibliometrics studies presented as to Activity Based Costing, Target and Kaizen Costing, Theory of Constraints and of Unity of Effort Production, using the first 17 editions of the Brazilian Congress of Costs (Congresso Brasileiro de Custos/CBC) as a database. Similarly to the methodological path of previous bibliometrics studies on the subject, a descriptive research was carried out alongside a quantitative approach, using the meta-analysis and the content analysis techniques. Results show that there is no regular distribution in articles published over the years, and that Activity Based Costing was the most researched, followed by the Theory of Constraints, and, finally, by Target Costing, Kaizen and Unity of Effort Production together. Results also indicate that books are still the main source of references for costing methods studies. The nature of the research approached practical and theoretical aspects; however, research focused on the various costing methods that made up the sample did not relate with each other.

title: Using rodogram function to characterize hurst coefficient in rock profiles

description: Abstract Roughness is a fundamental feature to define rock deformability and resistance. A detailed characterization of discontinuity surface geometry is essential for understanding some of the rock’s mechanical behaviors. Fractal geometry has been used by several authors to correlate parameters such as the Hurst coefficient for JRC (Joint Roughness coefficient) to better describe a surface geometry. Surface profiles might be characterized by a fractal dimension that represents the small scale of the geometric recurrence. In this paper, we propose to modify the methodology used to identify the Hurst coefficient incorporating the rodogram function in the JRC analysis. The proposed function is less influenced by drifting effects, and seems to be more precise than the commonly used variogram function. Robust mathematical models of spatial continuity can be a better alternative to characterize the roughness of rock discontinuities.

title: Proposal of surface electromyography signal acquisition protocols for masseter and temporalis muscles

description: Abstract Introduction The aim of this study was to propose a method of electrodes positioning on the superficial masseter and anterior temporalis muscles for surface electromyographic (sEMG) recordings in order to overcome some known methodological constraints. Methods Fifteen volunteers with normal occlusion participated in two experimental sessions within a 7 day-period. Surface electrodes were placed on two different locations that were based on palpable and individual anatomical references. Surface EMG signals (2000 Hz per channel; A/D: 16 bits; gain: 2000 X; band-pass filter: 20-500 Hz) were recorded under three conditions: mandibular rest position, 30% and 100% of maximum voluntary bite force. Three measurements of maximal bite force were taken by using a force transducer positioned over the lower right first molar region and the highest record was taken into account. The root mean square value was considered for analysis. Intraclass correlation coefficients (ICCs), paired t test, and the Bland-Altman method comprised the statistical analyses. The level of significance was set at 0.05. Results ICC records for right and left masseter and anterior temporalis muscles at T0 (first sEMG record) and T7 (second sEMG record) intervals were significantly different (p&lt;0.05). The results showed satisfactory to excellent reproducibility of RMS values at rest, MVBF and 30% MVBF, as well as for MVBF in kgf. Conclusion The results showed reliable reproducibility for the sEMG signal recording in masseter and anterior temporalis muscles from the protocols presented and under the three conditions investigated.

title: Hypoparathyroidism and pseudohypoparathyroidism: etiology, laboratory features and complications

description: ABSTRACT Objectives To identify a clinical profile and laboratory findings of a cohort of hypoparathyroidism patients and determine the prevalence and predictors for renal abnormalities. Materials and methods Data from medical records of five different visits were obtained, focusing on therapeutic doses of calcium and vitamin D, on laboratory tests and renal ultrasonography (USG). Results Fifty-five patients were identified, 42 females and 13 males; mean age of 44.5 and average time of the disease of 11.2 years. The most frequent etiology was post-surgical. Levels of serum calcium and creatinine increased between the first and last visits (p &lt; 0.001 and p &lt; 0.05, respectively); and serum levels of phosphate decreased during the same period (p &lt; 0.001). Out of the 55 patients, 40 had USG, and 10 (25%) presented with kidney calcifications. There was no significant difference in the amount of calcium and vitamin D doses among patients with kidney calcifications and others. No correlation between serum and urinary levels of calcium and the presence of calcification was found. Urinary calcium excretion in 24h was significantly higher in patients with kidney calcification (3.3 mg/kg/d) than in those without calcification (1.8 mg/kg/d) (p &lt; 0.05). Conclusions The reduction of hypocalcemia and hyperphosphatemia suggest an effectiveness of the treatment, and the increase in serum creatinine demonstrates an impairment of renal function during follow-up. Kidney calcifications were prevalent in this cohort, and higher urinary calcium excretion, even if still within the normal range, was associated with development of calcification. These findings suggest that lower rates of urinary calcium excretion should be aimed for in the management of hypoparathyroidism.

title: Attitudes and perceptions of faculty members in the process adopting innovation: The OpenCourseWare initiative at the University of Valencia, Spain

description: The OpenCourseWare project, an open learning resource repository, was established at the University of Valencia between 2008 and 2009. It initially consisted of only 10 subjects, none of which was in the field of Health Sciences. The objective of this research was to investigate the attitudes and perceptions of faculty members in the field of Health Sciences with regard to the project to identify strategies to increase its use and expand its coverage. We applied Rogers' innovation-diffusion theory along with a qualitative approach using theoretical sampling,semi-structured interviews and open coding. Theresults indicatetheexistenceof two categoriesof faculty members. Inthe first group, we findthose who adopt aninnovation early, have aninclination to participateinthe initiative,and a positive perception of the characteristics of the innovation. In the second, the largest category is composed of those who are more reluctant to participate and who have a negative perception of one or more of its characteristics. Identifying the nature of these two groups provides guidelines for further actions and research in marketing and distribution of such projects, training, awareness, and motivation required to increase the use of OpenCourseWare.

title: Evaluation of preoperative ultrasonographic and biochemical features of patients with aggressive parathyroid disease: is there a reliable predictive marker?

description: ABSTRACT Objective Parathyroid cancer (PC) represents &lt; 1% of cases of PHPT. Tumors demonstrating atypical histopathologic features and don’t fulfill criteria for carcinoma are classified as atypical adenomas (APA). The purpose of this study was to determine a biochemical or ultrasonographic feature that can predict aggressive disease requiring more extensive surgery and closer follow-up. Subjects and methods Twenty eight patients operated for PHPT and diagnosed with atypical adenoma (23 patients) or carcinoma (5 patients) were enrolled in this study. The control group consisted of 102 patients operated between the same dates and diagnosed with classical PA. Classical adenomas, atypical adenomas, and carcinomas were compared according to their biochemical and ultrasonographic parameters. Results Serum Ca levels were significantly higher in the PC group compared with the APA and classical PA groups. Serum median PTH, Serum ALP and UCa was significantly higher in the APA and carcinoma groups compared to the classical PA group. ROC analysis was made to determine the best cut off values for predicting aggressive disease were 12.45 mg/dL, 265.05 pg/mL, 154.5 IU/l, 348.5 mg/day and 21.5 mm for Ca, PTH, ALP, UCa and the adenoma diameter, respectively. Multivariate analysis showed that serum Ca, ALP and isoechoic/cystic appearance were independent predictors for aggressive disease. Conclusion Preoperatively high PTH, ALP, and UCa levels and large lesions with isoechoic or cystic appearances may be predictive of atypical adenoma or carcinoma in patients being evaluated for PHPT. In such cases, surgeons may prefer en bloc parathyroidectomy to minimally invasive surgery.

title: Metastatic lymph node characteristics as predictors of recurrence/persistence in the neck and distant metastases in differentiated thyroid cancer

description: ABSTRACT Objective: The aim of this study was to evaluate the association between this characteristic and outcomes in patients with lymph node metastasis in a Brazilian cohort. Subjects and methods: This study examined a retrospective cohort of adult patients diagnosed with differentiated thyroid cancer and lymph node metastases from 1998 to 2015 in two referral centers. Number, location, size and extranodal extension (ENE) of metastatic lymph nodes were assessed and correlated with response to initial therapy. Results: A greater number of metastatic nodes, larger size, presence of lateral neck disease and ENE were all associated with a lower probability of achieving an excellent response to initial therapy (p ≤ 0.05 for all these parameters). Local recurrent disease had a significant association with lymph node number (6 in the recurrence/persistence group versus 4 in the non-recurrent group; p = 0.02) and ENE (19.2 versus 75%, p = 0.03). Lateral neck disease was the only characteristic associated with distant metastasis and was present in 52.1% of the group without metastasis and 70.4% of the group with metastasis (p = 0.001). Conclusion: The lymph node characteristics were associated with response to initial therapy and neck recurrence/persistence, confirming the importance of the analysis of these factors in risk stratification in a Brazilian population and its possible use to tailor initial staging and long term follow-up.

title: ARE ESL/EFL SOFTWARE PROGRAMS EFFECTIVE FOR LANGUAGE LEARNING?

description: This study investigated the extent to which ESL/EFL software programs on the market develop language skills. A software evaluation instrument was used to evaluate fifteen ESL/EFL software programs for the technological, pedagogical and individualization features that would account for the incorporation of Communicative Language Teaching (CLT) principles and an interactive approach to computer use in language teaching. Results indicated that only three programs incorporated more than 75% of the technological features, four programs incorporated more than 70% of the pedagogical features, and only one program contained more than 70% of the features that allow for individualization of instruction. Overall, only two programs incorporated more than 70% of all analyzed features. The analysis of the programs provided evidence that the differentiating factor in ESL software programs lies not only in their pedagogical orientation, but also in how they incorporate CLT principles and an interactive approach to computer use into their design.
