Pollination and reproductive biology of thirteen species of Begonia in the Serra do Mar State Park, São Paulo, Brazil

The reproductive biology of 13 monoecious species of Begonia that occur in the Serra do Mar State Park, Sao Paulo, Brazil, was investigated. These species flower annually and present flowers with mostly white tepals, sweet odour, pollen as a reward but no nectar, numerous yellow stamens, and yellow styles. Anthesis is diurnal and floral duration is long (6 - 15 days). The unusual appearance of pistillate flowers of these species supports the view that they are intersexual mimics of the staminate flowers. Despite consistently high levels of fruit-set, none of the 11 species tested proved to be apomictic. In contrast to earlier reports of self-compatibility in Begonia , self-pollinations of B. integerrima and B. itatinensis produced no fruits or seeds, and the complete absence of pollen tubes in the styles of self-pollinated flowers of B. integerrima suggests that the species is self-incompatible. Flowers pollinated under natural conditions showed many pollen tubes that reached ovules, suggesting that adequate numbers of compatible pollen grains had been transported by pollinators. The principal pollinators were bees of the Apidae and Halictidae. Ten species of bees were observed to visit eight species of Begonia , and pollen collection occurred by vibration, except for Trigona spinipes . Visits to rewarding staminate flowers were significantly more frequent than visits to unrewarding pistillate flowers. Duration of visits to pistillate flowers also was significantly shorter than the duration of visits to staminate flowers. We conclude that visits to pistillate flowers occur by mistake but with sufficient frequency to allow for successful reproduction in natural populations of these species.
Emotional Intelligence and Job Performance of High School Female Teachers

Emotional intelligence (EI) has become a well-known concept in the field of work psychology. There has been an increasing realization that, beside other skills and attributes, EI is an important predictor of potential job performance. This present study aimed to explore EI as predictor of job performance among high school female teachers. The impact of work related attitudes, job satisfaction, turnover intention, and organizational commitment was also located on the relationship of EI and job performance. Female teachers (210), who had been teaching grade 10 students for 2-10 years in 35 randomly selected government high schools comprised the sample. Emotional Intelligence Test (Schutte et al., 1998), Job Satisfaction Scale (Warr, Cook, and Wall, 1979), Organizational Commitment Questionnaire (Mowday, Steers, and Porter, 1979), and Continuance Commitment Subscale (Allen and Meyer, 1990) were used to measure the study variables. Marks of students and self-evaluation forms were employed to measure the job performance of the teachers. A theoretical model was developed, positing EI predicting job performance via job attitudes; that is job satisfaction, organizational commitment, and turnover intentions. EI came out as a poor job performance predictor as was indicated by path analysis and regression analysis. However, teachers with high EI indicated more job satisfaction than teachers with low EI; and their students secured better grades. This has important implications for educational authorities, school administrators, and teachers in terms of teacher recruitment, training, performance and professional development.
The Influence of a Tutor’s Ideology and a Student’s Learning Style of Design College on the Achievement of Educational Objectives

This paper explores the potential influence of ideology on the education of design and focuses particularly upon the interaction between tutors and students. Structural Equation Models are constructed to investigate the relationship between the ideological style of the tutor and the learning style of the students and to assess the impact of these variables on the achievement of educational objectives in the field of design education. The results indicate that the potential influence of a tutor’s ideology on the total, cognitive and psychomotor educational objectives must be recognised and carefully considered in the education of design.
High-energy tail of the Galactic Center gamma-ray excess

Observations by the Fermi-LAT have uncovered a bright, spherically symmetric excess surrounding the center of the Milky Way galaxy. The spectrum of the gamma-ray excess peaks sharply at an energy ~2 GeV, exhibiting a hard spectrum at lower energies, and falls off quickly above an energy ~5 GeV. The spectrum of the excess above ~10 GeV is potentially an important discriminator between different physical models for its origin. We focus our study on observations of the gamma-ray excess at energies exceeding 10 GeV, finding: (1) a statistically significant excess remains in the energy range 9.5-47.5 GeV, which is not degenerate with known diffuse emission templates such as the Fermi Bubbles, (2) the radial profile of the excess at high energies remains relatively consistent with data near the spectral peak, (3) the data above ~5 GeV prefer a slightly greater ellipticity with a major axis oriented perpendicular to the Galactic plane. Using the recently developed non-Poissonian template fit, we find mild evidence for a point-source origin for the high-energy excess, although given the statistical and systematic uncertainties we show that a smooth origin of the high-energy emission cannot be ruled out. We discuss the implication of these findings for pulsar and dark matter models of the gamma-ray excess. Finally we provide a number of updated measurements of the gamma-ray excess, utilizing novel diffuse templates and the Pass 8 dataset.
Modeling lattice-matched InP-based multijunction solar cells

Currently, the multijunction solar cell structure gives the highest efficiency for photovoltaic solar cells. In this study, tandem, triple, and quadruple junction multijunction solar cell structures that include an InP subcell on InP substrate were investigated. A model that can calculate both the voltage–current characteristics and external quantum efficiency was demonstrated. The model gave fitted results with the experimental data for a single junction GaAs solar cell and a tandem solar cell that provides efficiency higher than 30%. The model was used to optimize the lattice-matched AlAsSb/InP tandem, AlAsSb/InP/InGaAsP triple, and AlAsSb/InP/InGaAsP/GaAsSb quadruple junction solar cell designs and the highest efficiencies obtained for these cells were 29.9%, 36.69%, and 42.79%, respectively, under AM1.5 spectrum without any sun concentration. This lattice-matched quadruple junction structure gives the opportunity of having high efficiency without wafer bonding.

Designing out terrorism: human factors issues in airport baggage inspection

All air passenger baggage is screened at airports by means of 2-D X-ray imaging which results in a computer display of each luggage item that is then visually searched by an operator (screener) for the presence of potential threat items (e.g. knifes, guns, improvised explosive devices [IED]). Despite improvements in screener training and available technology (e.g. image enhancement functions, threat image projection, 3-D X-ray imaging) the performance of screeners is variable which leads to the potential for terrorist threat to aircraft and passengers. A new training scheme to improve performance in baggage screening is under development (EPAULETS: Enhanced Perceptual Anti-terrorism Universal Luggage Examination Training System) and some of the initial human factors issues that underlie variable screener performance are considered.
Association Between ACE Gene Insertion (I)/Deletion (D) Polymorphism and Primary Hypertension in Turkish Patients of Trakya Region

ABSTRACT Hypertension is immensely common in Turkish subjects in Trakya region. The renin angiotensin system (RAS) helps maintain blood pressure and salt homeostasis and appears important in the pathogenesis of hypertension. Angiotensin I-converting enzyme (ACE) is a key component of RAS. Insertion/Deletion (I/D) polymorphism of the ACE gene has been implicated in the pathogenesis of cardiovascular diseases. In addition to this, the association between ACE I/D polymorphism and hypertension is controversial, when numerous studies have addressed the role of ACE I/D polymorphism in the development of hypertension, there were different studies showed that no correlation has been found between ACE I/D polymorphism and in the development of hypertension. The objective of our study was to investigate the relation between the ACE gene I/D polymorphism and primary hypertension in Turkish subjects in Trakya region. We analyzed the ACE gene I/D polymorphism in 79 patients with primary hypertension as a primary hypertensive group and 38 age matched healthy individuals as a control group by using a polymerase chain reaction assay, and agarose gel electrophoresis system. The genotype distributions were not different between the patients and normal control groups in the men. But the frequency of ACE Deletion/Deletion (DD) genotype in patients with primary hypertension (35.5%) was significantly higher than in controls (21.4%) in the women. This result suggested that ACE DD genotype may be associated with primary hypertension in the women, not in the men, and showed the possibility of ACE DD genotype as a potent risk factor for primary hypertension for the women not for the men.
PARTICLES CHARGING IN TUBULAR ELECTROSTATIC PRECIPITATORS WITH POLYGONAL COLLECTION ELECTRODES

The aim of this paper is to eliminate ambiguities that appear in the literature relating to the saturation charge of particles in electrostatic precipitators. Investigation of the influence of collection electrode geometry on electric field strenght in electrostatic precipitator, the saturate charge of particle directly depends on, is the second main goal. The numerical results for electric field and potential distribution for various cross sections (polygonal) of tubular electrostatic precipitator geometry are shown. This analysis may lead to a quantification of the efficiency of the electrostatic precipitator depending on the geometry of collection electrodes, whose shape affects the distribution of the electric field, thus creating the possibility of design improvement.
Subjective well being and basic needs: evidence from rural Guatemala

This paper deals with basic needs fulfillment interpreted in a subjective way. We develop a framework in which the basic needs of households in developing areas are valued from a subjective point of view. We estimate how certain indicators and assets influence basic needs perception. We compare income and perceived basic needs poverty measures, finding that they mismatch. We conclude that income-based approaches should be complemented with other indicators such as subjective satisfaction measures to understand development and measure poverty.
An Empirical Analysis of Growth Regimes

In this paper we apply cluster analysis to a dataset on economic growth in 61 countries for the period 1960-1985. We find four clusters of countries and show that they correspond to four growth regimes (stages of growth), and highlight which factors characterize the membership of a country to a growth regime. In particular: human capital and institutional quality appear increasing in the stages of growth, while other factors such as Government consumption, investment in physical capital, trade openness and natural resource abundance show a nonmonotonic pattern across growth regimes. Finally, we show that convergence emerges as a strong force only at the highest levels of development.
Effects of Varied Nitrogen Supply and Irrigation Methods on Distribution and Dynamics of Soil NO3-N during Maize Season

A field experiment was carried out to investigate the effects of different supply methods of nitrogen (N) fertilizer and irrigation on the spatial distribution and dynamics of soil NO 3 -N for maize ( Zea mays L.) grown in northwest China in 2012 and 2014. In 2012, there were three irrigation methods: alternate furrow irrigation (AI), fixed furrow irrigation (FI) and conventional furrow irrigation (CI). Three N supply methods: alternate N supply (AN), fixed N supply (FN) and conventional N supply (CN), were applied at each irrigation method. In 2014, the fixed treatments were excluded. Soil NO 3 -N in horizontal direction was measured to 100 cm soil profile. For 2012, at filling stage, compared to CI, AI increased soil NO 3 -N concentration under the plant by 4.5 to 7.4% in 0-40 cm soil profile and decreased that by 9.9 to 14.4% in 40-80 cm for three N supply methods. NO 3 -N concentration between two sides of the ridge was comparable for AN and CN coupled with AI or CI. When compared to CI, AI reduced soil NO 3 -N concentration in 60-100 cm by 4.8 to 8.7% from 12 collars stage to maturity over different positions when coupled with CN. Soil residual NO 3 -N at maturityin 0-100 cm was the lowest in AI coupled with CN or AN. The 2014 experiment verified the above results. Therefore, alternate furrow irrigation coupled with conventional or alternate N supply brought an optimum spatial distribution of soil NO 3 -N during maize season, resulting in little soil residual NO 3 -N at maturity.
In vivo plaque count of Streptococcus Mutans around orthodontic brackets bonded with two different adhesives

The prevention of the enamel demineralization at the periphery of the brackets is a significant challenge to orthodontic professionals. The aim of this clinical study was to compare the Streptococcus mutants count in the plaque surrounding two orthodontic adhesive types, Fuji Ortho LC and Enlight (Ormco). Materials and methods: A total of 13 patients (7 males and 6 females) needing fixed orthodontic appliance therapy were participated. A split mouth technique was followed with appliances bonded by two orthodontic adhesive types, Fuji Ortho LC and Enlight (Ormco). Saliva was collected before placement of appliances (T0) and again at three weeks (T1) and six weeks (T2) after placement of appliances. Plaque was collected from areas adjacent to brackets and buccal tubes at three weeks (T1) and six weeks (T2) after placement of appliances. The numbers (colony-forming units) of Streptococcus mutans were determined with the side-specific modified Strip-Mutans. Results: No significant modification in the number of Streptococcus mutans CFU in saliva was observed at both time intervals (T1) and (T2) after placement of appliances. The number of Streptococcus mutans CFU in plaque at both time intervals (T1) and (T2) was statistically lower in sites adjacent to Fuji Ortho LC than in those adjacent to Enlight (Ormco) adhesive. Conclusion: plaque surround brackets and tubes bonded with Fuji Ortho LC adhesive harbor less Streptococcus mutans and this will aid in prevention of enamel demineralization.
Technological Pedagogical Content Knowledge (TPACK) in Action

Abstract How does teachers’ technological pedagogical content knowledge (TPACK) inform their instructional planning? How can this knowledge be enhanced? In an interpretivist study of experienced secondary social studies teachers’ planning, we sought to discover clues to the nature and development of these teachers’ TPACK-in-action as it was expressed in their planning processes. Comparisons of interview data and planning products before and after engaging in professional development that addressed content-focused, TPACK-based learning activity types (Harris & Hofer, 2009) revealed three primary findings, each supported by participating teachers’ oral and written reflections upon their learning. The participating teachers’ (a) selection and use of learning activities and technologies became more conscious, strategic, and varied; (b) instructional planning became more student-centered, focusing primarily upon students’ intellectual, rather than affective, engagement; and (c) quality standards for technology integration were raised, resulting in deliberate decisions for more judicious educational technology use.
Muslim marriage (non) recognition: implications and possible solutions

Abstract Differences between traditional Muslim marriage practice and the statutory formalities required for entry into a legally recognised marriage in England and Wales have resulted in serious question-marks hanging over the legal status of a seemingly significant proportion of Muslim marriages. This article places the spotlight on the vulnerability of spouses who remain unaware of the lack of legal status which may attach to their marriage or who may have been misled by their spouse as to the latter’s intention to obtain legal recognition for the marriage. The article first considers the statutory formalities required under English law for entry into a legally recognised marriage before drawing on the most up-to-date empirical research to highlight the apparently widespread non-compliance with the formalities within the Muslim community. The article then reflects on the various practical implications which may arise for parties to an unrecognised Muslim marriage before considering how the situation may be ameliorated.
Indonesian Olympiad in Informatics

This article describes the experience of Indonesian Olympiad in Informatics (abbreviated as OKI in Indonesian) in introducing informatics to young generation in Indonesia through a form of competition. Organizing an informatics olympiad in a large developing country requires dealing with a myriad of challenges, such as unbalanced distribution of infrastructure development and poor human resource. In Indonesia, these challenges are dealt by staging a multi-tiered selection, concentrating on developing online training system and creating a strong cooperation with top universities. We analyze briefly how these efforts impact the spread of participation of OKI.
Uterine Tumors: Pathophysiologic Imaging with 16 -[F]fluoro-17-estradiol and F Fluorodeoxyglucose PET—Initial Experience

Tetsuya Tsujikawa, MD Yoshio Yoshida, MD, PhD Tetsuya Mori, PhD Tetsuji Kurokawa, MD, PhD Yasuhisa Fujibayashi, PhD Fumikazu Kotsuji, MD, PhD Hidehiko Okazawa, MD, PhD Purpose: To clarify prospectively the relationship between estrogen receptor (ER) expression and glucose metabolism by using 16 -[F]fluoro-17 -estradiol (FES) and fluorine 18 (F) fluorodeoxyglucose (FDG) positron emission tomography (PET) in patients with benign and malignant uterine tumors.
Exercise and diet therapy: Psychotherapists' beliefs and practices.

Two hundred thirty-two members of Division 29 of the American Psychological Association (46.4% of those randomly sampled) responded to a survey concerning their assessment and recommendation practices relating to nutrition and to exercise and physical fitness. Respondents reported assessing and recommending diet and exercise practices less frequently than other health behaviors, but many indicated conditions amenable to exercise and diet recommendations. Few therapists had received education in exercise and nutrition, but more than half believed that diet and exercise should be required as a component of the graduate school curriculum. The topics of exercise and nutrition have received considerable attention in recent years, as anecdotal and scientific evidence of benefits mounts. Findings of relations among exercise, diet, and cardiovascular risk reduction have stimulated research on other possible benefits of exercise and diet regimens. Many studies suggesting that exercise and nutrition therapies enhance psychological well-being have appeared. If psychotherapists were reading the research literature on the effects of exercise and nutrition on mental health, they would be encountering consistent positive findings (e.g., Folkins & Sime, 1981; Simons, Epstein, McGowna, & Kupfer, 1985). In addition, although the effect of nutrition on mental health has been much less intensely studied than has the effect of exercise, a number of writers have enthusiastically claimed that improved nutrition can enhance psychological well-being (e.g., Cheraskin & Ringsdorf, 1976; Pfeiffer, 1976; Sheinkin, Schachter, & Hutton, 1979). A group of mental health practitioners to whom the literature on exercise, nutrition, and mental health is especially relevant is that of practicing psychotherapists, who daily have the opportunity to prescribe exercise and nutrition therapy to clients seeking help. Actively prescribing such remedies would suggest that practicing therapists are convinced of its utility for treatment in the context of the present scientific and anecdotal evidence, whether justifiably so or not; the absence of such prescribing would suggest the absence of such conviction.

Tertiary giant lacewings (Neuroptera: Polystoechotidae): Revision and description of new taxa from western north America and Denmark

Synopsis A preliminary definition of the Polystoechotidae (Insecta, Neuroptera) based on wing characters is provided. Tertiary Polystoechotidae are revised; the genus Palaeopsychops Andersen (10 species) and the new collective genus Polystoechotites gen. n. (6 species) are recognised. Ten new species (eight named) are described from the earliest Early Eocene Fur Formation (Denmark) and the Early to early Middle Eocene Okanagan Highlands (Quilchena and Horsefly River, British Columbia, Canada and Republic, Washington, USA): Palaeopsychops quadratus sp. nov. (Fur Formation); Palaeopsychops setosus sp. nov. (Horsefly River); Palaeopsychops marringerae sp. nov., Palaeopsychops timmi sp. nov., Polystoechotites lewisi gen. et sp. nov., Polystoechotites barksdalae gen. et sp. nov., Polystoechotites falcatus gen. et sp. nov. (Republic); Palaeopsychops douglasae sp. nov., Polystoechotites sp. A, Polystoechotites sp. B (Quilchena). Polystoechotes piperatus Cockerell from Late Eocene of Florissant (Colorado, USA) is assigned to Polystoechotites. Neuroptera incertae sedis sp. A (Republic) is determined as either an aberrant polystoechotid, or belonging to a family of psychopsid‐like Neuroptera. Palaeopsychops setosus sp. nov. bears a dense cover of macrotrichia across a portion of the wing membrane, not previously known in the order. Extended floating time of polystoechotids increased negative taphonomic bias, in most depositional settings probably lowering their fossil assemblage representation. In some, taphonomic factors such as the presence of mat‐forming organisms may have enhanced their fossil representation to greater than their community representation. This scenario is proposed for the Fur Formation, consistent with lithological evidence and palaeogeographic reconstruction. Dispersal of Palaeopsychops between Denmark and the Okanagan Highlands (direction unknown) was probably by the North Atlantic route, not before the late Palaeocene, during periods of continuous land connection between North America and northern Europe. Polystoechotidae in the Eocene, as today, appear to have ranged in forested regions of microthermal to lower mesothermal climate.
