Discourses on Underrepresentation : Why Problematization Matters

Despite decades of research on and efforts to increase the lownumbers ofwomen in engineering inmany parts of theworld, underrepresentation persists. This paper analyzes recent engineering education scholarship to determine what reasons are given to explain why underrepresentation is a problem, in other words, how underrepresentation is problematized. Using discourse analysis as the theoretical lens, and drawing on prior research that employed similar methods and theoretical perspectives, this paper examines an international dataset of engineering education journal articles and conference proceedings from1995–2008. Four categories of problematizations are identified and discussed in order to advance critical reflection that could be beneficial in moving forward discussions about underrepresentation.
Joint variance-ratio tests of random walks in China's closed-end fund market

This paper examines the random walk behavior of four China’s non-US equity closed-end funds including Greater China Fund (GCH), China Fund (CHN), Jardine Fleming China Region Fund (JFC), and Taiwan Greater China Fund (TFC) using joint variance ratio tests. The results from the joint variance ratio procedures reveal that the null hypothesis that the closed-end fund returns follow random walk should be rejected in all of the cases. From these results it is inferred that the four China’s closed-end funds under consideration do not exhibit random walk behavior for the sample period. The implication of the results is that the weak-form market efficiency hypothesis does not hold for the four China’s closed-end funds market.
Metric perturbations of extremal surfaces

Motivated by the HRRT-formula for holographic entanglement entropy, we consider the following question: what are the position and the surface area of extremal surfaces in a perturbed geometry, given their anchor on the asymptotic boundary? We derive explicit expressions for the change in position and surface area, thereby providing a closed form expression for the canonical energy. We find that a perturbation governed by some small parameter λ yields an expansion of the surface area in terms of a highly non-local expression involving multiple integrals of geometric quantities over the original extremal surface.
PHYTOTOXIC EFFECT OF TECTONA GRANDIS ( L . f . ) LEAF EXTRACTS ON GROWTH AND DEVELOPMENTAL CHANGES OF PENNISETUM GLAUCUM ( L . ) R . BR . AND ELEUSINE CORACANA ( Gaertn )

The present study investigates the growth and developmental changes of Pearlmillet [(Pennisetum glaucum (L.) R.Br. )] and Ragi [Eleusine coracana (Gaertn )] under pot culture experiments with different concentrations of aqueous leaf extracts (5, 10, 20, 30 and 50g/l) of Teak. Teak leaf extracts showed an inhibitory and stimulatory effects on germination, seedling length, biomass, pigments and biochemical constituents of pearl millet and ragi. The 5g/l concentration of extract stimulated the seed germination, seedling growth and biochemical constituents of pearl millet and ragi. The higher concentrations (10, 20, 30and 50g/l) showed an inhibitory effects in all the parameters studied in the two economically important cereals. The degree of retardation was dependent on the concentration of the Teak leaf extracts. Root length, Shoot length, Biomass and Biochemical constituents of ragi seedlings were highly reduced at 50g/l concentrations of aqueous leaf extracts of Teak. Between pearl millet and ragi seedlings, more allelopathic influence was observed in ragi than pearl millet seedlings.
Family Formation in Ireland Trends, Data Needs and Implications: Report to Family Affairs Unit, Department of Social, Community and Family Affairs

This study provides an overview of existing knowledge regarding the family in Ireland today. It focuses in particular on three major issues: the long-term decline in fertility, the growth and pattern of lone parenthood and changes in household and family size. It emphasises how poor the existing Irish data relating to the family are, and suggests how they could be improved.
Interannual Variability of the Atlantic Hadley Circulation in Boreal Summer and Its Impacts on Tropical Cyclone Activity

AbstractA novel method was developed to define the regional Hadley circulation (HC) in terms of the meridional streamfunction. The interannual variability of the Atlantic HC in boreal summer was examined using EOF analysis. The leading mode (M1), explaining more than 45% of the variances, is associated with the intensity change of the ITCZ. M1 is significantly correlated to multiple climate factors and has strong impacts on Atlantic tropical cyclone (TC) activity. In the positive (negative) phase of M1, the ITCZ is stronger (weaker) than normal, and more (fewer) TCs form over the main development region (MDR) with a larger (smaller) fraction of storms intensifying into major hurricanes. Analyses showed that the large-scale dynamic and thermodynamic conditions associated with a stronger ITCZ are more favorable for TC activity.The roles of tropical easterly waves in modulating the Atlantic TC activity are highlighted. In the positive phase of M1, the wave activity is significantly enhanced over the MDR and .
Pathways to Consensual Popularity and Mating Opportunities in Ontogenetic Perspective

In this paper, we investigated different behavioral patterns for achieving consensual popularity exhibited by antisocial and prosocial types of individuals. These patterns were investigated from pre-adolescence through late adolescence, and for both genders. Results revealed that Populistic (antisocial) individuals were high in bullying and low in academics; Social-populars (prosocial) showed the opposite pattern. Both types were higher in physical attractiveness and fashionability than unpopular individuals, who were the most likely to be bullied. Substance abuse was high in both popular types. Both populistic and social-popular boys and girls were far more likely to be dating than unpopular boys and girls.
Detection of Helicobacter-like organisms in Thoroughbred horses from Venezuela.

The aim of this study was to detect the presence of Helicobacter infection in Thoroughbred in Venezuela. One hundred and thirty six Thoroughbreds with signs for Equine gastric ulcer syndrome (EGUS) were studied in the National Race Track La Rinconada Caracas Venezuela. Necropsies were performed in all horses and samples of gastric tissue were collected. The tissue samples were fixed in formalin and processed by conventional HE no hyperemia, no hyperkeratosis. Grade 1 Mucosa is intact but there are areas of hyperemia and/or hyperkeratosis 26/136. Grade 2 small, single or multi-focal erosions or ulcers 38/136. Grade 3 Large, single or multi-focal ulcers, or extensive erosions and sloughing 36/136. Grade 4 Extensive ulcers, with areas with deep submucosal damage 34/136. Using the Warthin-Starry special stain, Giemsa and Blue Toluidine with spiral-shaped bacteria were evidenced found in 52, Grade 1: 13/52, Grade 2: 10, Grade 3: 16, Grade 4: 13. There seemed to be no association between Warthin-Starry, Giemsa and Blue Toluidine stain with the grade and location of lesions. Urease activity was then demonstrated in fifty-two equine. To conclude, we detected the presence of Helicobacter Like Organisms in the gastric mucosa from thoroughbred horses with EGUS.
Assessing habitat quality for conservation using an integrated occurrence-mortality model

Summary 1. Habitat suitability models are usually produced using species presence or habitat selection, without taking into account the demographic performance of the population considered. These models cannot distinguish between sink and source habitats, causing problems especially for species with low reproductive rates and high susceptibility to low levels of mortality as in the case of the critically endangered Apennine brown bear Ursus arctos marsicanus . 2. We developed a spatial model based on bear presence (2544 locations) and mortality data (37 locations) used as proxies for demographic performance. We integrated an occurrence and a mortality-risk Ecological Niche Factor Analysis model into a final two-dimensional model that can be used to distinguish between attractive sink-like and source-like habitat. 3. Our integrated model indicates that a traditional habitat suitability model can provide misleading management and conservation indications, as 43% of the area suitable for the occurrence model is associated with high mortality risk. Areas of source-like habitat for the Apennine bears (highly elevated areas rich in beech forests, far from roads, and with low human density and cultivated fields) are still present, including outside the currently occupied range. However, attractive sink-like habitat (associated with high levels of pasture, low extent of mountain meadows, low steepness, low elevation, and closeness to secondary and urban roads) are present even inside protected areas. 4. Synthesis and applications . Identifying attractive sink-like habitat is crucial to prevent inappropriate management and to effectively address conservation issues: whereas existing source-like habitats should be preserved to halt habitat loss and degradation, attractive sink-like habitat should be managed to mitigate mortality risks or to decrease their attractiveness. In particular, areaspecific management interventions and proactive actions (increased patrolling, road closure, human activity management, threat monitoring, etc.) aimed at reducing human-caused mortality are critical for the Apennine brown bear.
Laccaria bicolor MiSSP8 is a small-secreted protein decisive for the establishment of the ectomycorrhizal symbiosis

The ectomycorrhizal symbiosis is a predominant tree-microbe interaction in forest ecosystems sustaining tree growth and health. Its establishment and functioning implies a long-term and intimate relationship between the soil-borne fungi and the roots of trees. Mycorrhiza-induced Small Secreted Proteins (MiSSPs) are hypothesized as keystone symbiotic genes, required to set up the symbiosis by modifying the host metabolism and/or building the symbiotic interfaces. Since L. bicolor MiSSP8 is the third most highly induced MiSSPs in symbiotic tissues and it is expressed in fruiting bodies, we report its functional study by analysing phenotypes of L. bicolor MiSSP8-RNAi mutants and MiSSP8 in planta subcellular localization. The MiSSP8-RNAi knockdown mutants are impaired in their mycorrhization ability with Populus, with the lack of fungal mantle and Hartig net development. When expressed heterologously in planta, MiSSP8 shows a punctate localization that partially colocalize with plasmodesmata. Moreover, MiSSP8 displays a fungal-specific repetitive motif, present in proteins from both saprotrophic and ectomycorrhizal fungi. MiSSP8 is a Laccaria-specific small-secreted protein required for early stages of ectomycorrhizal symbiosis. Our data suggest that MiSSP8 has a possible dual role: one in basic fungal biology regulating hyphal aggregation and another in planta, related to its plasmodesmata co-localization.
Title Generalized PSK in space-time coding

A wireless communication system using multiple antennas promises reliable transmission under Rayleigh flat fading assumptions. Design criteria and practical schemes have been presented for both coherent and noncoherent communication channels. In this paper, we generalize one-dimensional (1-D) phase-shift keying (PSK) signals and introduce space–time constellations from generalized PSK (GPSK) signals based on the complex and real orthogonal designs. The resulting space–time constellations reallocate the energy for each transmitting antenna and feature good diversity products; consequently, their performances are better than some of the existing comparable codes. Moreover, since the maximum-likelihood (ML) decoding of our proposed codes can be decomposed to 1-D PSK signal demodulation, the ML decoding of our codes can be implemented in a very efficient way.
Effect of Brand Loyalty on Purchase Intention in Cosmetics Industry

There is a huge expenditure for cosmetics estimated around the world. Many competitors try to capture the market and compete aggressively. The principle of this study is to examine the impact of brand loyalty on the purchase intention of customer or evaluate that how much buying behavior of consumer are influenced by brand loyalty and what factors or variable influence the brand loyalty. There are six variables that influence on brand loyalty is brand name, product quality, price, design, promotion, store environment. The 80 questioner is filled from the female consumer of cosmetic product to investigate the purchase intention influenced by brand loyalty. For this purpose linear regression method used for analysis. The result of this study shows that there is a positive significant impact of brand loyalty on purchase intention and also there is a positive significant relationship between the variables (brand name, product quality, price, design, promotion, store environment) and brand loyalty of cosmetics.
ournal of C osmology and A stroparticle hysics J Transition redshift: new constraints from parametric and nonparametric methods

In this paper, we use the cosmokinematics approach to study the accelerated expansion of the Universe. This is a model independent approach and depends only on the assumption that the Universe is homogeneous and isotropic and is described by the FRW metric. We parametrize the deceleration parameter, q ( z ), to constrain the transition redshift ( z t ) at which the expansion of the Universe goes from a decelerating to an accelerating phase. We use three diﬀerent parametrizations of q ( z ) namely, q I ( z ) = q 1 + q 2 z , q II ( z ) = q 3 + q 4 ln(1+ z ) and q III ( z ) = 12 + q 5 (1+ z ) 2 . A joint analysis of the age of galaxies, strong lensing and supernovae Ia data indicates that the transition redshift is less than unity i.e. z t < 1. We also use a nonparametric approach (LOESS+SIMEX) to constrain z t . This too gives z t < 1 which is consistent with the value obtained by the parametric
NATURAL CONVECTION HEAT TRANSFER FROM FIN ARRAYS- EXPERIMENTAL AND THEORETICALAL STUDY ON EFFECT OF INCLINATION OF BASE ON HEAT TRANSFER

The problem of natural convection heat transfer from fin arrays with inclination is studied experimentally and theoretically to find the effect of inclination of the base of the fin array on heat transfer rate. A numerical model is developed by taking an enclosure, which is formed by two adjacent vertical fins and horizontal base. Results obtained from this enclosure are used to predict heat transfer rate from the fin array. All the governing equations related to fluid in the enclosure, together with the heat conduction equation in both the fins are solved by using Alternate Direct Implicit method. Numerical results are obtained for temperature along the length of the fin and in the fluid in the enclosure. The experimental studies have been also carried out on two geometric orientations viz., (a) vertical base with vertical fins (vertical fin array) and (b) horizontal base with vertical fins (horizontal fin array), with the five different inclinations like 0 0 , 30 0 , 45 0 , 60 0 , and 90 0 . The experimental results are compared with the numerical results computed by the theoretical analysis shows the good agreement.
Biological data from post mortem analysis of otters in Hungary

In this paper we examined the characteristics of reproduction parameters, stomach content and inner organ weights on carcasses (male, n=67, female n=57, unknown n=3) of otters (Lutra lutra) collected in Hungary between 1999 and 2006. Most otter carcasses (90.6%) were collected as road casualties. In breeding females (n=28), the mean (±SE) number of placental scars was 2.22±0.17. One female was pregnant (3 embryos). Suckling were detected at four females, the number of active teats (2-4) equalling the number of placental scars. Reproduction period, calculated from the age of juveniles, was long (from winter to summer). No seasonal difference was found in the gonado-somatic index values of adult males, and births were estimated to have occurred from winter to summer. The stomach was empty in 31% of the cases, while mean weight of the stomach content was 49 g the main food eaten by otters was small-size, non-commercial fish. In the adult age group, the organ weight index of the kidneys (P<0.01) and adrenal glands (P<0.05) was greater in females, while in case of the other organs: heart, liver, spleen, tyroid glands and lungs no significant difference was found.
Comparative antioxidant and antimicrobial studies of cold and hot bark hydromethanolic extract of Couroupita guianensis Aubl

Couroupita guianensis, known by its common name as cannon ball tree, belongs to Lecythidaceae family, native of south and central America, India and Sri lanka. It’s been in use in traditional medicine and worshipped as sacred tree in india. With the importance of tree in various medicinal aspects as per the reports the present investigation was carried to access the phytochemical components, free radical scavenging and antimicrobial activity of cold and hot hydromethanolic extracts from the barks of medicinally important Couroupita guanensis. Phytochemical screening revealed the presence of total antioxidants, flavonoids, phenols and phytosterols in both cold and hot extracts. Quantitative estimations of the phytochemicals revealed the presence of high contents of total antioxidant activity (598.4 µg/ml), phenol content activity of (417.52 µg/ml) and phytosterols of (133.92 µg/ml) in cold hydromethanolic extracts compared to the hot hydromethanolic extract. The presence of high flavonoid content (417.52 µg/ml) was recorded in hot extract compared to the cold extract. Hot extract gave more scavenging activity with IC50 value (33.5 µg/ml). ABTS radical scavenging activity was found to be more in cold extract with IC50 values (24. µg/ml). Antimicrobial assay showed activity with B. cereus (13.00±0.00mm) and S.aureus (15.00±0.00mm) bacteria showed maximum zone of inhibition compared to the hot extract whereas C. albicans (13.00±O.00mm) showing maximum zone of inhibition compared to the cold extract and was not sensitive to any other fungal forms tested. This investigation pays way to consider Couroupita guianensis, with highly potential antioxidant and antimicrobial components, be used in pharmaceutical companies for the development of phytomedicine for the therapy and treatments.
MEASURING MODERATIONS : A CROSS CULTURAL AND COMPARATIVE SERVICES CONSUMPTION STUDY BETWEEN BRAZILIANS AND CANADIANS

This study ́s purpose is to examine relational benefits and consequent variables on Brazilian and Canadian consumers by moderating cultural idiosyncrasies. Comprised by a quantitative nature descriptive research 297 Brazilians and 207 Canadians were surveyed. Data was submitted to statistical tests via MANOVA comparisons, canonical correlation and regressive model moderations so as to verify the herein proposed technique. The study also gave rise to methodological contributions given the development of computational scripts employed to support the identification of each regression ́s construct ́s strength, orientation and path. Comparative analyses substantiate that when assessing services, Brazilians are more demanding than Canadians. Given that culturally, the former still feature greater power distance, there is ground for recommending that offering special treatment to Brazilians is an important satisfaction with employees leveraging factor. On the other hand, when unlike other fellow countrymen, Canadians receive such benefits, a general feeling arises that benefits and knacks of the kind should not be meant for but a few, shaping the service offer into one that is deemed unequal, within a society that is clearly more egalitarian than that of Brazil. Outcomes might further prove to be of use to the narrowing of Brazil-Canada business ties.
Agronomic performance of Indian wheat varieties and genetic stocks known for outstanding chapati quality characteristics

The aim of the present study was to evaluate set of wheat genotypes in one location for their agronomic performance and chapati quality. The cultivars included the tall traditional wheat of the pre-dwarfing era, which were known to excel for chapati quality. This set also included varieties known to have good chapati quality, commercially grown wheats, advanced lines and genetic stocks excelling in one or other quality attribute. All these genotypes developed for different component traits were evaluated along with the recently released high yielding varieties to assess their quality. The mean chapati score of these genotypes revealed that the tall varieties had a distinct edge over others and are the best resource available for this trait. C306 had a high mean chapati score of 8.17 followed by C518, C591 and C273. The released varieties WG357, HD2733 and PBW343 were intermediate in chapati quality whereas the genetic stocks WH1103 and WH712 had lowest score in the group. Among other agronomic traits recorded the traditional varieties were tall and had lower yields than the recently released varieties. The tall varieties had a slightly higher test weight. The environmental conditions and the quantitative nature of the chapati quality did not auger well with the set of genotypes tested however, better and stable performance of the tall traditional varieties. C306 the wheat variety released in 1965 for cultivation has remained the best quality genotype over the years and was also established from this study.
Achieving Online Relationship Marketing via Tourism Blogs: A Social Network Perspective

Drawing upon the literature on social network analysis, this research examines how part-time marketers use tourism blogs to conduct relationship marketing with their customers. The findings from an interpretive case study indicate that the network pictures of part-time blog marketers can be categorized into three distinct models: the “fan club,” the “compliance,” and the “creative outlet” models. Our findings also suggest that different network pictures lead to different network management strategies for blogs. Moreover, providing instrumental support and especially material support by blog marketers play significant roles in aggrandizing this transitivity, which helps to attract more visitors to blog sites. We believe that the innovation and the potential connections derived from the individualistic styles of some bloggers and the hedonic emotional support given to tourism blogs should not be overlooked. Our findings also indicate that more incentives and freedom should be provided to tourism business bloggers in order to prosper in their grassroots use of technology.
Catalyst/Feedstock Ratio Effect on FCC Using Different Catalysts Samples

The present study is a follow-up to a recent authors contribution which describes the effect of the C/O (catalyst/oil) ratio on catalytic cracking activity and catalyst deactivation. This study, while valuable, was limited to one fluidized catalytic cracking (FCC) catalyst. The aim of the present study is to consider the C/O effect using three FCC catalysts with different activities and acidities. Catalysts were characterized in terms of crystallinity, total acidity, specific surface Area (SSA), temperature programmed ammonia desorption (NH3-TPD), and pyridine chemisorption. 1,3,5-TIPB (1,3,5-tri-isopropyl benzene) catalytic cracking runs were carried out in a bench-scale mini-fluidized batch unit CREC (chemical reactor engineering centre) riser simulator. All data were taken at 550 °C with a contact time of 7 s. Every experiment involved 0.2 g of 1,3,5-TIPB with the amount of catalyst changing in the 0.12–1 g range. The resulting 0.6–5 g oil/g cat ratios showed a consistent 1,3,5-TIPB conversion increasing first, then stabilizing, and finally decreasing modestly. On the other hand, coke formation and undesirable benzene selectivity always rose. Thus, the reported results show that catalyst density affects both catalyst coking and deactivation, displaying an optimum C/O ratio, achieving maximum hydrocarbon conversions in FCC units.
