Lise öğrencilerinin kimya dersi sınıf öğrenme ortamı, öğretmenin iletişim davranışları ve öğrenme stratejilerini algılamaları.

Field: Arts and Humanities (Social Sciences)

The purposes of this study were to explore students’ perceptions of the extent to which constructivist approaches are present in chemistry classes at high school level in Turkey, to assess students’ perceptions of their chemistry teachers’ communication behaviours in their classroom learning environments and to investigate the learning strategies of students in chemistry classes considering school type, gender, and grade level differences. In this study, the Constructivist Learning Environment Questionnaire (CLES), the Teacher Communication Behaviour v Questionnaire (TCBQ) and the Motivated Strategies for Learning Questionnaire (MSLQ) were used as measuring instruments. In addition, the questionnaires included some questions for demographic characteristics of participants. The study was conducted in conveniently selected two schools (private and public) in Ankara with a total of 994 ninth and tenth grade students in the second term of 2006-2007 semesters. Data obtained from the administration of measuring instruments by using the analysis of multivariate analysis of variance (MANOVA) The results of the study indicated that school type, gender and grade level of the students had significant effect on perception of classroom learning environment, teacher’ communication behaviour and perceived use of learning strategies. For instance, students in private schools perceived their classroom-learning environment more constructivist than student in public school. In addition girls rated that, their learning environment and teachers’ communication behaviours more favourably than did boys. The study also showed that students use rehearsal-learning strategy mostly in their chemistry classrooms.
Exploring performance attribution

Field: Business, Management and Accounting (Social Sciences)

Purpose Accreditation to the ISO 9001 Quality Management Systems Standard has proven to be a persistent and growing phenomenon in services and manufacturing, yet to date little attempt has been made to explore how performance results in cross‐sectional research may be attributed to different causation mechanisms and how their influences may alter over time. This paper aims to fill this gap. Design/methodology/approach The paper defines four possible causation mechanisms before searching and analysing the empirical literature on quality management system certification to ISO 9001 and business performance for evidence of their causal influence. Findings From the analyses, it is found that the benefit that can safely be attributed to the treatment‐effect of ISO 9001 accreditation is lower waste; while the benefits of lower costs and better quality are less likely unless motives for adoption are developmental rather than externally driven. From an analysis of longitudinal studies a strong selection‐mechanism is found where more profitable firms have a greater propensity to adopt than less profitable firms. From the finding propositions are developed to show how the influence of these mechanisms change over time. Research limitations/implications The existence of the selection‐mechanism has profound implications for interpreting business performance achievements because the benefits that are attributed to the treatment‐effect from adopting quality management system standards are likely to be greatly inflated by the influence of the selection‐mechanism. The author suggests that richer theory is needed that can incorporate bi‐directional influences and new research is needed to explore the underlying causes of the selection effect. Originality/value The paper is believed to be the first to systematically explore attribution of performance in the ISO 9001 literature. Its findings provide new insights into the complexities of attribution of performance in studies of new practices and systems.

Contributions to Frequency Offset and Time Delay Estimation

Field: Computer Science (Physical Sciences)

The demand for reliable high rate and efficient communication is ever increasing. In this thesis we look at two different problems in such systems, and their possible solutions. In recent years orthogonal frequency division multiplexing (OFDM) has gone from a promising data transmission technique to become a mainstream technique used in several current and future standards. The main attractive property of OFDM is that it is inherently resilient to multipath reflections because of its long symbol time. However, this comes at the cost of a relatively high sensitivity to carrier frequency offsets (CFOs). In this thesis we present a technique for CFO estimation in OFDM systems that is based on locating the spectral minimas within so-called null or virtual subcarriers embedded in the spectrum.~The spectral minimas are found iteratively over a number of symbols and is therefore mainly useful for frequency offset tracking or in systems where an estimate is not immediately required, such as in TV or radio broadcasting systems. However, complexity wise the estimator is relatively easy to implement and it does not need any extra redundancy beside a nonmodulated subcarrier. The estimator performance is studied both in a channel with additive white Gaussian noise and in a frequency selective channel environment. A goal for many years has been to be able to implement as much as possible of a radio system in the digital domain, the ultimate goal being so called software defined radio (SDR). One important part of an SDR receiver is the high speed analog-to-digital converter(ADC) and one path to reach this goal is to use a number of parallel, time-interleaved, ADCs. Such ADCs are, however, sensitive to sampling instant offsets, DC offset and gain offset. This thesis also discusses iterative time-delay estimators (TDEs) utilizing adjustable fractional-delay filters. The TDEs could for example be used to estimate and calibrate the relative delay between the ADCs comprising the time interleaved ADC. TDEs using a direct correlator and an average squared difference function are compared. Furthermore, an analysis of the effects of the batch length dependence is presented.
PULMONARY EMBOLISM IN INFANCY

Field: Medicine (Health Sciences)

A case of pulmonary embolism and thrombosis is reported because of the rarity of the condition in infancy. A review of the literature reveals the following cases with an age range of from 1 to 4½2 years. Wessen1reported a case of fatal pulmonary embolism in a boy, aged 4 years, following resection of the rib in "pleural" pneumonia. Lutz2reported observations made at autopsy in twenty-two cases of measles; six of the patients had extensive pulmonary thrombosis and two a portal thrombosis. Three of the eight patients had an associated purulent otitis media and five a sinus thrombosis. Péhu and Horand3stated that after embolic causes, the most common etiologic factor of pulmonary thrombosis in children is otitis media. Guillemot.4in speaking of the otogenous origin of pulmonary gangrene, stated that otologists consider pulmonary metastases frequent following a thrombophlebitis of the lateral sinus and rare
FACF: fuzzy areas-based collaborative filtering for point-of-interest recommendation

Field: Computer Science (Physical Sciences)

Several online social networks collect information from their users' interactions (co-tagging of photos, co-rating of products, etc.) producing a large amount of activity-based data. As a consequence, this kind of information is used by these social networks to provide their users with recommendations about new products or friends. Moreover, recommendation systems (RS) become capable to predict a person's activity with no special infrastructure or hardware, such as RFID tags, or by using video and audio. In that sense, we propose a technique to provide personalised points-of-interest (POIs) recommendations for users of location-based social networks (LBSNs). Our technique assumes users' preferences can be characterised by their visited locations, which is shared by them on LBSN, collaboratively exposing important features as, for instance, areas-of-interest (AOIs) and POIs popularity. Therefore, our technique, named fuzzy areas-based collaborative filtering, uses users' activities to model their preferences and recommend the next visits to them. We have performed experiments over two real LBSN datasets and the obtained results have shown our technique outperforms location collaborative filtering at almost all of the experimental evaluation. Therefore, by fuzzy clustering of AOIs, FACF is suitable to check the popularity of POIs to improve POIs recommendation.
Understanding perioperative bowel preparation for colorectal surgery

Field: Medicine (Health Sciences)

Bowel preparation is an important perioperative measure in elective colorectal surgery. The goal is to empty the contents of the intestine and reduce the number of bacteria in the intestine, so as to reduce the risk of surgical-related infections, ensure the safety of the surgery and facilitate a smooth postoperative recovery. Compared with the upper abdominal surgery, colorectal surgery is usually associated with a higher risk of postoperative infection, including incision and abdominal infections, anastomotic leakage and infection-related intestinal obstruction, and of infections of distant organs, such as pneumonia and urinary tract infections. With the application of evidence-based medicine in clinical practice, especially the popularization of enhanced recovery after surgery (ERAS), the unfavorable factors of bowel preparation, such as physical discomfort, interference with normal physiology, and increased care burden, have received increasing attention. Relevant clinical trials and meta-analyses continue to emerge, and the clinical significance of bowel preparation in preventing postoperative infection has been questioned.
Intracellular Ca2+ Signalling in Secretory Cells

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

ABSTRACT The secretion of ions and fluid plays a critical role in a variety of physiological activities that are vital to homeostatic mechanisms in animals. Control of such secretory activity is achieved by a range of neurotransmitters and hormones many of which act intracellularly by generating the second messenger inositol 1,4,5-trisphosphate (InsP3) and increasing cytosolic free calcium ion concentrations ([Ca2+]i). These increases are achieved by a combination of the InsP3-induced release of Ca2+ from specific intracellular stores and the activation of Ca2+ entry from the extracellular environment. The [Ca2+]i signal represents a balance between the adequate activation of components of the secretory mechanism and the avoidance of [Ca2+]i levels that are toxic to the cell. Resting [Ca2+]i is maintained low by the action of Ca2+ pumps on the intracellular stores and plasma membrane, with the result that gradients for Ca2+ movement into the cytosol from either of these two sources are very large and there is considerable potential for achieving rapid increases in [Ca2+]i. Consequently, for successful Ca2+ signalling, it is imperative that these two mechanisms of raising [Ca2+]i (i.e. Ca2+ release and Ca2+ entry) are closely integrated. Current models emphasize the activation of Ca2+ entry as a downstream result of the emptying of the intracellular stores (‘capacitative’ model). Whilst this may be true for situations of maximal stimulation, recent experiments on the oscillatory [Ca2+]i responses typical of more physiological levels of stimulation indicate a previously unsuspected, independent activation of Ca2+ entry involving arachidonic acid. This arachidonic-acid-activated entry plays a key role, along with InsP3, in inducing the repetitive release of Ca2+ from the stores to produce the [Ca2+]i oscillations. In this way, the two components responsible for the elevation of [Ca2+]i are intimately related and their dual effects closely coordinated, resulting in the finely tuned control of agonist-induced changes in [Ca2+]i.

Omission of axillary lymph node dissection after positive sentinel lymph node: Validity and safety among early breast cancer patients treated with mastectomy

Field: Medicine (Health Sciences)

Background: ACOSOG Z0011 trial showed that axillary lymph node dissection (ALND) had no impact on recurrence and survival in patients with positive sentinel lymph node (SLN) after breast-conserving surgery. However, it is still unknown if omission of ALND can be applicable to patients treated with mastectomy. The aim of this study was to evaluate whether ALND could be safely omitted for patients with SLN–positive breast cancer after mastectomy. Methods: From a prospective database of 296 patients with clinically node-negative breast cancer who underwent mastectomy and sentinel lymph node biopsy (SLNB) from March 2006 to December 2016, 81 patients who had positive SLNs were analyzed. Patients treated with neoadjuvant chemotherapy were excluded from the analysis. Lymphatic mapping was performed with a combined method of blue dye and radioisotope. Results: The median age was 57.0 (range: 32-85) years and the median tumor size was 2.5 (range: 0.6-7.9) cm. Of 81 patients, 23 (28.4%) patients omitted ALND. Patients with SLNB alone were more likely to have smaller SLN involvements (p < 0.001): micrometastasis was identified in 13 (56.5%) patients in SLNB-alone group and 9 (15.5%) patients in ALND group. The number of positive SLN was comparable between SLNB-alone (median: 1.0, range: 1-6) and ALND groups (median: 1.0, range: 1-5) (p = 0.063). There was no significant difference in characteristics including age, tumor size and tumor subtypes between the two groups. Post-mastectomy radiotherapy was performed in 5 (21.7%) patients with SLNB alone and 16 (27.6%) patients with ALND (p = 0.588). The majority of patients with macrometastatic SLN received adjuvant chemotherapy in both groups (83.3% vs. 75.5%, p = 0.562). After a median follow-up of 54.7 months, no axillary recurrence was observed in both groups and 5-year disease-free survival was not significantly different between the two groups (75.0% vs. 88.8%, p = 0.489). Lymphedema was observed significantly more often after ALND than after SLNB (22.4% vs. 4.3%, p = 0.045). Conclusions: These data suggested that ALND could be safely omitted in SLN-positive breast cancer patients treated with mastectomy and appropriate systemic therapy.

O conhecimento dos profissionais de enfermagem sobre as lesões por pressões em Unidade de Terapia Intensiva

Field: Nursing (Health Sciences)

Objective: To analyze the knowledge of nursing professionals about the assessment, classification and prevention of pressure injuries in an adult Intensive Care Unit of a philanthropic hospital in the Vale do Itajaí region. Methodology: This is a descriptive and exploratory study, with a quantitative approach, carried out with nursing professionals from an adult ICU. For data collection, the Caliri-Pieper Pressure Injury Knowledge Test (TCLP Caliri-Pieper) was used, a validated instrument to assess theoretical knowledge on the topic. Results: Participants achieved correct answers of 84.1% and 72.7% on questions related to the assessment of pressure injuries. Regarding the classification of these injuries, the correct answers varied between 36.4% and 97.7%. Knowledge about prevention showed a significant discrepancy, ranging from 4.5% to 100.0%. Conclusion: The results demonstrate that the professionals evaluated have a satisfactory level of knowledge about the evaluation and classification of pressure injuries. However, the wide variation in knowledge about prevention indicates the need for continuous training to improve care practice and ensure more effective strategies for preventing these injuries in the adult ICU.
Descriptive study for look-alike and sound-alike medicines based on local language peculiarities

Field: Health Professions (Health Sciences)

The existence of confusing drug names was considered one of the leading causes of medication errors. The aim of the study was to summarize the potential sources for errors associated with look-alike and sound-alike (LASA) medicines, to provide overview of the most common patterns and offer recommendations of safety strategies to help mitigate the problem. A standardized questionnaire was conducted for a period of 1 month in 2011. The collected data was statistically analyzed with Microsoft Excel 2007 and SPSS version 17.0. The total of 93 questionnaires was obtained. Two hundred and twenty-three (223) unique LASA drug pairs were identified with prevalence to brand names. The modal Bulgarian brand medicine name had 7 letters, 3 syllables and 1 word. The average generic drug name had 10 letters, 4 syllables and 1 word. The top 15 highest risk-potential pairs from both groups were classified by the values of the Dice coefficient and analyzed by possible impact on prescription and pharmacy practice. The results of the study showed that look-alike medicine names were a possible source of medication errors and threat to patient safety in everyday practice. Safety strategies were needed to reduce the risk of medication errors in community and hospital pharmacies related to LASA drugs.
Segmental chromosome aberrations and clinical response impact outcome of inss stage III patients ≥18 months with unfavorable histology and without MYCN amplification: A Children’s Oncology Group (COG) report.

Field: Medicine (Health Sciences)

10502 Background: Patients with INSS stage III neuroblastoma represent a heterogeneous population with respect to disease presentation and prognosis and controversy exists regarding the most effective treatment algorithms. Patients ≥18 months of age with INSS Stage 3 tumors that are unfavorable histology (UH) and MYCN-non-amplified ( MYCN-NA) represent a small cohort of patients with an outcome intermediate of those with favorable histology tumors and MYCN amplified tumors. The presence of Segmental Chromosome Aberrations (SCA) may predict outcome; however, their impact specifically in this cohort of patients has not been reported. Methods: Eligible patients enrolled on therapeutic protocols A3973 (n=34), ANBL0532 (n=27), and biology protocol ANBL00B1 (n=101 with 29 treated on A3973/ANBL0532) with stage III disease, MYCN–NA, UH and age ≥18 months at diagnosis were analyzed. Copy number alterations and loss of heterozygosity (LOH) for relevant loci were scored for gains/losses by two independent reviewers. Results: The 5-year EFS/OS for children ≥18 months with stage III, MYCN–NA, UH disease treated on A3973 and ANBL0532 was 73.0±8.1%/87.9±5.9% and 61.4±10.2%/ 73.0±9.2%, respectively, with no statistical differences in EFS or OS between the two cohorts (p=0.1286 and p=0.2180, respectively). In the combined cohort of patients enrolled on A3973 and ANBL0532, statistically significant differences were found (p(s) <0.0001) in patients with CR/VGPR (n=39) and PR (n=13) having better outcomes than <PR (n=5) (5-year EFS: 74.0±7.6% vs. 75.0±12.5% vs. 0%; 5-year OS: 84.4±6.2% vs. 100% vs. 20.0±17.9%). Subjects with chromosome 11q loss/LOH had an inferior outcome in comparison to those without 11q loss/LOH (10-year EFS: 44.4+/-24.1% vs. 78.1+/-9.4%, p=0.01; 10-year OS: 62.4+/-15.9% vs. 85.9+/-7.8%, p=0.02)). Patients with 1p loss/LOH and 2p gain also showed trend towards worse event-free survival (p=0.086 and p=0.088, not statistically significant) but not in overall survival. Conclusions: High-risk therapy that included single myeloablative therapy led to an 81.6±5.3%5-year OS in patients ≥18 months with UH and MYCN–NA stage III neuroblastoma. Response to therapy is a powerful predictor of survival and the presence of chromosome 11q loss/LOH is also associated with inferior outcomes. These patients should continue to be treated on high-risk clinical trials.
