Coronal transients and metric type II radio bursts - II. Accelerations at low coronal heights

In the companion Paper I, Mancuso & Raymond (2004) investigated the relationship between type ii and coronal mass ejection (CME) activity for a sample of twenty-nine CME/shock events that occurred between March and December 1999. Most of the events appeared to lead the type ii emission locations by several minutes and the two sets of speeds were not well-correlated, in apparent disagreement with a CME-driven origin interpretation of the coronal shocks. The above discrepancies were attributed to an artifact effect due to geometry, favoring emission at the flanks of the CME leading edges in correspondence with denser low-Alfven-speed coronal structures, where shock strengths are enhanced. An important caveat in the analysis carried out in Paper I is that the conclusions that supported the CME-driven shock front-flank scenario were based on sunward-extrapolated CME trajectories deduced from the analysis of Large Angle and Spectrometric Coronagraph (SOHO/LASCO) observations in the outer corona that might not be accurate at low coronal heights where significant accelerations should be present before the CMEs acquire the speeds inferred by coronagraphic images. In the present paper, we re-examine the above relationship for a subset of ten events by integrating the LASCO measurements with ancillary CME observations taken by other instruments (MLSO/Mk4, SOHO/EIT, and UVCS) at coronal heights comparable to the typical type ii radio emissions (1.2–2.5 $R_{\odot}$). We investigate the bias introduced in the sunward extrapolation of LASCO data and discuss whether the presence of previously undetected CME accelerations at low coronal heights might have affected the conclusions put forth in the CME-driven shock front-flank scenario proposed in Paper I. We show that the new set of observations neither solve the problem of the timing between CMEs and shocks nor improve the correlation between CME and shock speeds, although acceleration effects are found to be important at the typical metric type ii heights and must be taken into account for a proper analysis of the CME/shock relationship.
The impacts of an invasive alien plant and its removal on native bees

Although the alien Impatiens glandulifera successfully invades riparian habitats and is visited by native insects, knowledge of its impact on native bees is limited. We assessed pollinator abundance in field sites where I. glandulifera was absent, present or had been experimentally removed. We measured insect visitation to flowers of potted native plants and to I. glandulifera. Bombus spp. comprised the highest proportion of visitors in invaded sites, whereas solitary bees made up the highest proportion in sites where I. glandulifera was removed. More bees, especially mediumand long-tongued Bombus spp. (B. pascuorum and B. hortorum), foraged on I. glandulifera than the native plant species (possibly because the alien was more abundant). We detected no impact of invasion on standardised pollinator abundance, B. pascuorum abundance, nor functional insect diversity, which may be due to variable climatic conditions. We suggest that future studies focus on impacts on rare or specialised pollinator taxa. Bombus / Impatiens glandulifera / nectar secretion rate / nectar sugar concentration / Syrphidae
Studying the Interstellar Medium of H II/BCD Galaxies Using IFU Spectroscopy

We review the results from our studies, and previous published work, on the spatially resolved physical properties of a sample of H II/BCD galaxies, as obtained mainly from integral-field unit spectroscopy with Gemini/GMOS and VLT/VIMOS. We confirm that, within observational uncertainties, our sample galaxies show nearly spatially constant chemical abundances similar to other low-mass starburst galaxies. They also show He II 4686 emission with the properties being suggestive of a mix of excitation sources and with Wolf-Rayet stars being excluded as the primary ones. Finally, in this contribution, we include a list of all H II/BCD galaxies studied thus far with integral-field unit spectroscopy.
The impact of charges on mutual fund returns

This article provides metrics to analyse the impact of ongoing fees, one-off charges and inflation on the returns of mutual funds. Preliminary evidence for the EU fund industry suggests that over the three– year horizon, from 2013 to 2015, ongoing fees, one-off charges and inflation reduced the returns available to investors by 29% of gross returns on average or, in absolute terms, 252bps. While reductions vary across jurisdictions, asset classes and client types, they apply to all market segments: Relative return reductions range from 11% for passive equity fund shares to 44% for retail fund shares in bond mutual funds. Absolute reductions vary from 74 to 398bps, respectively. Relative and absolute return reductions for actively managed and retail fund shares tend to exceed those of passively managed and institutional fund shares. In general, these reductions are driven mainly by total expenses, while sales fees act as a further driver. Investors’ real returns are further reduced by inflation. The PRIIPs/MiFID framework will provide additional cost information, including distribution fees, to be taken into account, with particular consideration of the impact such costs could have on return reductions. In addition, we evaluate whether investors do indeed take fund charges and net returns into account when making investment decisions. Despite the impact of fees and charges on the net outcome to investors, these costs do not seem to be reflected in investor choices, given that aggregate net flows to EU fund shares evidently react hardly at all to management fees, and even less so to cost-adjusted net returns.
Antideuterons from decaying gravitino dark matter

From the point of view of Dark Matter searches, antideuteron are an interesting species of cosmic rays. In the past eighteen years much progress has been done in the understanding of these cosmic rays but this did not translate into experimental efforts to actually detect these particles. In this work, starting from a specific case of dark matter candidate with relatively generic features, we study some sources of theoretical uncertainties and show that the margin of improvement beyond the limits already set by cosmic-ray antiproton are quite narrow and anyway unachievable for the next generation of experiments.
AIR Study

During the years 2014–2016 the University of Salento performed the “Impact of Air Quality on Health of Residents in the Municipalities of Cutrofiano, Galatina, Sogliano Cavour, Soleto and Sternatia” (IMP.AIR) study, an epidemiological-molecular research project aiming to evaluate early DNA damage in children living in an area of Salento with high incidence of lung cancer among the male population. One hundred and twenty-two children aged 6–8 years attending primary school were enrolled and the frequency of micronucleated cells (MNC) in oral mucosa was evaluated. In addition, a questionnaire was administered to parents to obtain information about personal data, anthropometric characteristics and lifestyles (physical activity, food habits, family context) of the children and perform a multivariate analysis to detect any factors associated with MNC occurrence. Data on airborne pollutants detected in the study area were acquired by the Regional Agency for the Environmental Protection. The presence of MNC was highlighted in about 42% of children with a mean MNC frequency of 0.49‰. The frequency of MNC was associated to obesity, consumption of red or processed meat and having a mother who smokes. Moreover, the prevalence of biomarkers was higher than in another area of Salento not included in the cluster area.
Timing of debt issues: Evidence from a panel of Tunisian and French firms

Recent literature argues that market timing becomes the factor that shapes financing policies. However, empirical studies on debt market timing still less numerous than those on equity market timing. This paper seeks to investigate the relevance of market timing considerations on debt issues using a panel of Tunisian and French listed firms. We have documented that net debt issuance is a decrease function of the market monetary rate. Moreover, our findings reveals that Tunisian firms succeed to raise their values by issuing debt when they expect that interest rates will increase. By contrast, french firms fail to reduce their overall cost of capital.
Entropy Distribution in a Quantum Informational Circuit of Tunable Szilard Engines

This paper explores the possibility of extending the existing model of a single-particle Quantum Szilard Engine to take advantage of some features of quantum information for driving typical mechanical systems. It focuses on devices that output mechanical work, extracting energy from a single thermal reservoir at the cost of increasing the entropy of a qubit; the reverse process is also considered. In this alternative, several engines may share the information carried by the same qubit, although its interception will prove completely worthless for any illegitimate user. To this end, multi-partite quantum entanglement is employed. Besides, some changes in the cycle of the standard single-particle Quantum Szilard Engine are described, which lend more flexibility to meeting additional requirements in typical mechanical systems. The modifications allow having qubit input and output states of adjustable entropy. This feature enables the possibility of chaining the qubit between engines so that its output state from one can be used as an input state for another. Finally, another tweak is presented that allows for tuning the average output force of the engine.
Time flew by: Reading about movement of different speeds distorts people's perceptions of time.

How humans conceive of abstract domains such as time is a fundamental question in the cognitive sciences. Many theorists hold that we ground the abstract in the concrete, and understand time through the domain of space. Just as we can move through time quickly or slowly, we can move through space quickly or slowly: this study aims to examine to what extent our perception of time is dependent on space. Participants read a story that described slow movement (e.g., strolled), fast movement (e.g., raced) or movement without reference to speed (e.g., travelled) and were asked to provide a prospective time estimation of how long they had spent reading. Estimated reading times for fast stories were significantly shorter than those for neutral and slow stories. This finding indicates that even low-level judgements of temporal duration depend on spatial mappings, and suggesting that people simulate the attentional allocation of the protagonist during language comprehension.
Lecithotrophic nauplius of the family Dirivultidae (Copepoda; Siphonostomatoida) hatched on board over the Mid-Atlantic Ridge (5 S)

A copepod nauplius of the family Dirivultidae Humes & Dojiri 1980 is described for the first time. The lecithotrophic nauplius of the widespread symbiotic copepod Stygiopontius pectinatus Humes 1987 was released from females bearing paired egg sacs that included only one yolky embryo each. The ovigerous females of S. pectinatus were washed from the branchial chamber of alvinocaridid shrimps (Rimicaris exoculata Williams & Rona 1986) collected at a deep-sea hydrothermal field on the Mid-Atlantic Ridge at 5� S (Red Lion site, chimney ‘Shrimps Farm’, depth 3,048 m) by ROV Quest 4000 and maintained in a laboratory on the R/V METEOR (cruise M64/1, 2005). The nauplius of S. pectinatus, appears to be a stage I nauplius because it bears only one pair of caudal setae and the setose bud of maxilla 1 is absent. Like nauplii of other copepods of the order Siphonostomatoida, this nauplius of S. pectinatus possesses a reduced labrum and the body is filled with yolky granules; it also lacks a masticatory process on the antennal coxa. The presence of two inner setae (instead of one seta) on the mandibular endopod is hypothesized to be a primitive character of dirivultids that distinguishes them from the remaining siphonostomatoid genera. The Dirivultidae is a widespread and diverse family of copepods endemic to the deep-sea hydrothermal vents of the Pacific and Atlantic Oceans. Morphological features of the planktonic nauplius of S. pectinatus suggest nutritional independence during their dispersal.
How Personal Response Systems Promote Active Learning in Science Education

This study examines the effect of using personal response system (PRS) on students’ academic performance and their attitude towards science. Three research questions were addressed in the study: (1) Is there any difference in academic achievement of 5 th grade students when it is used PRS in science and technology courses? (2) Does PRS effect 5 th graders’ attitudes towards science? (3) What are the 5 th graders’ attitudes towards PRS use in the classroom? The results show that there is no difference in terms of achievement between pre-test and post-test scores in both groups. On the other hand, there is a positive difference on attitudes towards science on behalf of the experimental groups. In addition, boys were found to be more positive to PRS than girls based on the PRS attitude scale. The qualitative component involved focus group discussion with six students and an interview with the class teacher. Students are also observed while they were using the PRS in the classroom. Participants provided positive feedback regarding the use of PRS and requested the increase in use because they felt the use of PRS supported and improved their classroom learning, made the course more fun, and increased the course participation. They also enjoyed the peer discussions that instructors facilitated with regard to the use of PRS. The teacher was also positive about using PRS in his classroom.

Corporate Social Responsibility a Business Strategy or a Social Endeavour: Review of Literature for Sustainability Approach

Among many scholars globally, there are two schools of thought; one group believes that CSR should be mainly used as a social endeavour and the other thinks it should be linked to the corporate financial performance strategy. This paper aims to analyse the theories behind the social endeavor approach or the corporate strategy approach of CSR initiatives leads to sustainability of projects. The most important factor of all is the continuous support that a government and society at large expects from its corporate businesses in the building of its economy; ensuring projects are correctly selected, being sustainable and offering opportunities to improve corporate performance and society in general. Therefore, this paper focuses on identifying the theories behind appropriate approaches one should take when selecting a CSR initiative i.e. deciding between social endeavor or the strategic perspective in order to deliver sustainability of these initiatives. Keywords: Social endeavor, strategic CSR, CSR, sustainability, biological environment, social environment, core competencies and satisfaction.
Dependence of the Thermal Conductivity of BiFeO₃ Thin Films on Polarization and Structure

The role of the ferroelectric polarization state and crystal structure in determining the room-temperature thermal conductivity of epitaxial BiFeO 3 thin films is investigated. The ferroelectric domain configuration is varied by changing the oxygen partial pressure during growth, as well as by polarizing the samples by the application of an in situ electric field during the thermal conductivity measurement. However, little or no dependence of thermal conductivity on the ferroelectric domain structure is observed. In contrast, the thermal conductivity significantly depends on the morphotropic phase structure, being about 2 = 3 as large in tetragonal-like compared to rhombohedral-like BiFeO 3 film. The substantial structural dependence of thermal conductivity found here may provide a route to reversible manipulation of thermal properties.
Effect of NH4+/NO3- ratios on the growth and bolting stem glucosinolate content of Chinese kale (Brassica alboglabra L.H. Bailey).

Glucosinolates (GSs) are a group of plant secondary metabolites mainly found in Brassica that contain abundant nitrogen (N) and have anticarcinogenic effects on human health. GS levels are affected by nutrient availability, including the NH4 + /NO3 - ratio of the soil. Our objective was to examine the influence of NH4 + /NO3 - ratio on the growth and bolting stem GS content of Chinese kale (Brassica alboglabra L.H. Bailey). Seedlings were grown in five culture solutions with the same nitrogen level (15 mmol L -1 ), but different ratios of NH4 + /NO3 - (100/0, 75/25, 50/50, 25/75 and 0/100). As the NH4 + /NO3 - ratio increased from 0/100 to 75/25, there was no significant difference in growth characteristics (P > 0.05), but in the NH4 + only treatment the height and aboveground fresh weight decreased significantly (P 0.05) indicating that there was no direct correlation between the glucosinolate content and N/S ratio change. Our results suggest that a NH4 + /NO3 - ratio of 50/50 in fertilizer application can increase the GS content in bolting stems, but the underlying mechanisms need to be studied further.
Do Pulmonary Thromboemboli Have any Relation with Seasonal Variation? (Cross Sectional Study in North- West Iran) Pulmoner Tromboembolizmin Mevsimsel Değişikliklerle Bir İlişkisi Var midir? (Kuzeybati İran'dan Kesitsel bir Çalişma)

Objective: In some studies, the eff ect of seasonal variations on the incidence of disease is proven. Seasonal variation is discussed in the development of pulmonary thromboembolism (PTE) because the eff ect of these variations on the incidence of PTE disease was diff erent according to diff erent studies, The results of the studies which have been done so far have not shown any relation. The purpose of this study is to determine whether seasonal variations have any eff ect on the incidence of pulmonary thromboembolism. Materials and Methods: This research is a cross sectional study carried out on 158 hospitalized patients who were diagnosed as PTE between 2007 and 2008 in the Imam Reza educational and remedial center in Tabriz. Descriptive analysis is run on all variables and Chi-square method is used in evaluation of the diff erence among the groups. Results: In this research 158 patients, who were diagnosed as suff ering from PTE, were examined. The highest rate of incidence was in Spring and the rates of incidence in seasons in order are as follows: Spring 46 (29.1%) patients, Winter 42 (26.6%), Autumn 35 (22.2%), and Summer 35 (22.2%). In this study no sign of any meaningful diff erence in the number of patients in the diff erent seasons was observed (P=0.32). Conclusions: In this study on 158 patients suff ering from PTE, no meaningful relation between the seasons and the incidence of PTE was found. Studies with more samples are needed to support the fi nding and eff ects of seasonal
Connecting teaching practice to student efficacy in undergraduate mathematics

Academic efficacy plays a critical role in student success in math learning at all levels due to its impact on persistence, motivation, and academic performance. This research aimed to connect student efficacy with key aspects of the instructional environment in six undergraduate math classes. Student surveys indicated significant differences in mean efficacy between classes, as well as significant differences in student perceptions of teacher behavior between the efficacy groups. Findings from observations of the classes revealed that key aspects of the instructional discourse varied by efficacy group. Instructors in higher efficacy classes tended to have more personal connections with students and used more positive and encouraging language, particularly in response to student errors. These findings mirror the results of similar studies at the K-12 level and have important implications for teaching practice in higher education.
THE INFLUENCE OF RETAIL STORE CHARACTERISTICS ON CONSUMER PURCHASE INTENTION (CASE STUDY IN MULTI MART MEGA MALL MANADO)

ABSTRACT To fulfill customers’ needs and wants, companies create and offer products and services to consumer. In order to offer products and services, a company needs a distributor to sell their products or services directly to consumer. Ajzen theory is used in this research of consumer purchase intention. The purpose of this study is to analyze which retail store characteristics; product assortment, service quality, store atmosphere, and store location influence on purchase intention. This study is using purposive sampling technique by distribute 100 questionnaires to the people who have visited Multi Mart Mega Mall Manado and using Multiple Regression Analysis. As a result, retail store characteristics influence on consumer purchase intention simultaneously. Service quality and store location are significantly influence on consumer purchase intention partially, whereas product assortment and store atmosphere does not influence on consumer purchase intention. Multi Mart Mega Mall should provide a good service and comfortable atmosphere to attract more consumers. Keywords: Product Assortment, Service Quality, Store Atmosphere, Store Location, Purchase Intention.
Assessment of Process Parameters in Abrasive Waterjet Cutting of Granite

Abrasive waterjet cutting is one of the non-traditional cutting processes capable of cutting wide range of hard-to-cut materials. This paper assesses the influence of process parameters on depth of cut which is an important cutting performance measure in abrasive waterjet cutting of granite. Experiments were conducted in varying water pressure, nozzle traverse speed, abrasive mass flow rate and standoff distance for cutting granite tiles using abrasive waterjet cutting process. The effects of these parameters on depth of cut have been studied based on the experimental results. In order to correctly select the process parameters, an empirical model for the prediction of depth of cut in abrasive waterjet cutting of granite is developed using regression analysis. This developed model has been verified with the experimental results that reveal a high applicability of the model within the experimental range used. Keywords—abrasive waterjet, empirical model, garnet, granite, regression analysis.
Regional Poverty Post-2000 : The Lost Decade

The strong U.S. real income gains and reductions in poverty during the 1990s were largely erased in the following decade, which contained two economic recessions and tepid job growth otherwise. Areas most affected by weak U.S. economic performance could be expected to also have experienced the largest increases in poverty, particularly if interregional labor market adjustment is increasingly limited. We examine this issue, finding that not only was regional poverty affected by regional labor demand shocks, the effect was stronger post-2000, particularly in the long run. Consistent with the poverty results are findings of greater post-2000 regional labor demand effects on employment rates and reduced population adjustments to asymmetric labor demand shocks.
Professional development communities as a model for staff development online

In traditional approaches to professional development, much effort has been devoted to enhancement of the use of technology. However, the challenge now is to encourage the use of pedagogically-sound technologies. In this paper we discuss models of online professional development that include a 'whole of institutional approach' to staff development of online teaching skills and professional development that engages staff in reflective practice and immerses them in experiential learning online. We conclude that transformative and reflective models of online professional development are more likely to be sustainable and effective in supporting professional learning communities when introducing technological innovations in teaching.
