Interannual variability in an atlas of trace element signatures for determining population connectivity

Natural trace element signatures have increasingly been used to track the dispersal of marine larvae, and these studies require an atlas of potential source populations with distinctive elemental signatures. To determine whether natal site atlases could be used repeatedly and to identify site characteristics that yield the best results, we built atlases in 5 consecutive years using embryos of the porcelain crab Petrolisthes cinctipesthat were collected from 15 sites spanning 190 km of the open coast of northern California, USA. We analyzed the elemental composition of the embryos using a discriminant function optimization procedure to determine the suite of ele- ments that resulted in the best reclassification success for individual sites and groups of sites each year. No single element or group of elements succeeded in discriminating the origins of embryos every year, and the reclassification success of the atlas varied at all spatial scales among years. Average reclassification success at the site level ranged annually from 39.5 to 54.3% correct, and combining sites into 2 or 3 areas improved the overall reclassification success to 72.5 to 97.7% cor- rect. Sites with (1) distinctive elemental compositions of rocks, (2) unusual habitats, (3) consistent freshwater input, (4) consistent anthropogenic inputs, or (5) complex local oceano graphy had the highest reclassification success (up to 86.7% correct), but interannual variation in runoff reduced the temporal stability of the atlas. To improve population connectivity estimates, future trace ele- ment studies should consider these 5 key characteristics when selecting sites and anticipate tem- poral variation in natal site signatures.
Educational Experiences and Shifts in Group Consciousness: Studying Women

This study takes a multifaceted approach to group consciousness. The authors assessed changes in women’s feminist consciousness due to their exposure to feminism through women’s studies. Feminist consciousness was measured at the beginning and end of a semester during which some research participants were enrolled in an introductory women’s studies course. Women’s studies students were compared with students who were interested, but not enrolled, in women’s studies. As expected, women’s studies students showed an increase on several aspects of feminist consciousness, whereas non-women’s studies students did not. Non-women’s studies students became less sensitive to sexism. It is also noteworthy that, although they became more feminist, women’s studies students did not become more negative toward men.
Generation of a Large-scale Magnetic Field in a Convective Full-sphere Cross-helicity Dynamo

We study the effects of the cross-helicity in the full-sphere large-scale mean-field dynamo models of a 0.3 M⊙ star rotating with a period of 10 days. In exploring several dynamo scenarios that stem from magnetic field generation by the cross-helicity effect, we found that the cross-helicity provides the natural generation mechanisms for the large-scale scale axisymmetric and nonaxisymmetric magnetic field. Therefore, the rotating stars with convective envelopes can produce a large-scale magnetic field generated solely due to the turbulent cross-helicity effect (we call it γ2-dynamo). Using mean-field models we compare the properties of the large-scale magnetic field organization that stems from dynamo mechanisms based on the kinetic helicity (associated with the α2 dynamos) and cross-helicity. For the fully convective stars, both generation mechanisms can maintain large-scale dynamos even for the solid body rotation law inside the star. The nonaxisymmetric magnetic configurations become preferable when the cross-helicity and the α-effect operate independently of each other. This corresponds to situations with purely γ2 or α2 dynamos. The combination of these scenarios, i.e., the γ2α2 dynamo, can generate preferably axisymmetric, dipole-like magnetic fields at strengths of several kGs. Thus, we found a new dynamo scenario that is able to generate an axisymmetric magnetic field even in the case of a solid body rotation of the star. We discuss the possible applications of our findings to stellar observations.
External environment impact on business performance in digital creative industry: Dynamic capability as mediating variable

All companies face the challenge on how to create a sustainable competitive advantage, especially in the rapidly changing business environment, which is dynamic and highly turbulent. Digital creative industry is an industry that combines elements of creative and digital in its products and services. Indonesia has great potential in the development of digital creative industry, since their digital creative actors are able to generate competitive creative contents. This study aims to explore the impact of dynamic capability as a mediator of business performance in the face of external environment changing in the digital creative industries in Indonesia. A total of 96 respondents participated in this study. This study used a quantitative method with survey approach. The analysis technique used is structural equation modeling (SEM) to test the hypothesis and SmartPLS 3.0 Program as a tool in data processing. This study looked at the dynamic capability as the emerging paradigm of modern business that drive sustained high performance in the rapidly changing environment. The limitation of this research is the scope of research which only covers some areas in Indonesia, so it is expected that further research can expand the area coverage.
Nitrogen deposition and its impact on forest ecosystems in the Czech Republic - change in soil chemistry and ground vegetation

Abstract: A repeated soil survey (1995 and 2006) on 66 ICP Forests pair plots in the Czech Republic revealed a significant relationship between modeled nitrogen deposition and nitrogen concentration in the soil. Nitrogen deposition was modeled for the years 1995, 2004 and 2006. We found a more significant relationship between deposition data in 2004 and soil data in 2006 than between deposition and soil data from the same year 2006. Concentration of total nitrogen in forest soil increased from 1995 to 2006. Forest soil showed effects of increased nitrogen input from the humus layer to around 20 cm depth of mineral soil. The occurrence and cover of nitrophilous species in the herb layer increased from 1995 to 2006 in 25% of the analyzed plots, which corresponds to the nitrogen increase in forest soil. The results suggest that nitrogen deposition still represents a threat for Czech forest ecosystems.
Do Hedge Funds Possess Private Information about IPO Stocks? Evidence from Post-IPO Holdings

Using hedge funds' holdings of IPO stocks, we find that stocks with hedge fund holdings beyond what can be explained by publicly available information yield abnormal returns, suggesting that hedge funds possess private information in IPO stocks. Moreover, compared to other investors, hedge funds have more predictive ability for future stock returns in post-IPO trading and are able to sell IPO stocks before underperforming periods start. Finally, hedge funds earn higher abnormal returns in “connected” stocks when their prime brokers serve as the IPO underwriters, indicating that such connection is an important source of private information for hedge funds.
Effects of land-use change on Nitisols properties in a tropical climate

El cambio en el uso de la tierra, especialmente la conversión de bosques nativos en tierras cultivadas ejerce un impacto sobre las propiedades físicas, químicas e hidrofísicas de los suelos. El objetivo de este estudio fue evaluar la influencia de diferentes sistemas de manejo de un suelo tropical reflejado en algunas de sus propiedades físicas, químicas e hidrofísicas. Se evaluaron nueve perfiles de un suelo Nitisol agrupado en tres categorías: (I) bosque nativo (Referencia > 30 años); (II) suelos anteriormente cultivados y luego convertidos en pastizales (Conservados > 10 años); y (III) suelos bajo cultivo continuado (Agrogénicos > 50 años). Las variables analizadas fueron materia orgánica, densidad aparente, densidad real, porosidad, capacidad de campo, textura e índice estructural. Los resultados determinaron que la acción de las técnicas agrícolas tradicionales en ambientes tropicales produce una excesiva degradación de las propiedades del suelo. El contenido de materia orgánica e índice estructural muestran una relación lineal con un alto grado de dependencia (R2=0,99). La densidad aparente promedio para los perfiles (I) y (II) fue menor (P<0,05) que los valores de densidad aparente del perfil (III). En los análisis de regresión a medida que aumenta la densidad aparente disminuye la capacidad de campo y la tendencia observada para (I) y (II) es lineal, mientras que para (III) es polinómica con (R2=0,83), pudiendo estar influenciado por los valores más altos de la densidad aparente, mayor compactación, menor índice estructural, materia orgánica y porosidad en correspondencia con los otros perfiles.
Impact of spraying incubated eggs submitted to high temperature with ascorbic acid on embryonic development, hatchability, and some physiological responses of hatched chicks

Abstract Three hundred and sixty Hubbard broiler eggs were divided into two equal groups. In the first group, eggs were incubated at 37.5 °C for up to 19 d, while those in the second group were incubated at the same temperature except for 3 d (days 6, 7, and 8) when they were exposed to 40.0 °C for 3 h each day. Eggs were equally classified into three ascorbic acid (AA) treatments. The first one was sprayed with distilled water (control), while the second and third treatments were sprayed with same solution but containing 20 and 30 g AA L-1, respectively. The highest embryo weight (EW) per gram and lowest yolk sac weight (YSW) per gram were obtained in the chronic group (P ≤ 0.05). Embryonic mortalities were significantly (P ≤ 0.05) increased, while hatchability was significantly decreased in the chronic group compared with the control group. Chick weight (g) and glucose and triiodothyronine (T3) levels were significantly lower (P ≤ 0.05) in the chronic group compared with the control group. The heterophil–lymphocyte (H/L) ratio was significantly (P ≤ 0.01) affected by incubation temperature. Body weight (g) and percentages of liver, spleen, and bursa of Fabricius were significantly (P ≤ 0.05) lower in broilers in the chronic group compared with the control group. Referring to AA treatment, EWs (g) were not affected, whereas YSW per gram, packed cell volume (PCV) (%), red blood cells (RBCs) (106), H/L ratio, and bursa percentage were significantly (P ≤ 0.05) affected.
Scaling limit of the radial Poissonian web

We consider a variant of the radial spanning tree introduced by Baccelli and Bordenave. Like the original model, our model is a tree rooted at the origin, built on the realization of a planar Poisson point process. Unlike it, the paths of our model have independent jumps. We show that locally our diusively rescaled tree, seen as the collection of the paths connecting its sites to the root, converges in distribution to the Brownian Bridge Web, which is roughly speaking a collection of coalescing Brownian bridges starting from all the points of a planar strip perpendicular to the time axis, and ending at the origin.
EFFECTS OF COGNITIVE BEHAVIOURAL THERAPY ON LOW SELF –ESTEEM AMONG SECONDARY SCHOOL STUDENT IN DELTA STATE

This study seeks to determine the effects of cognitive behavioural therapy on students with low self-esteem in Ethiope-East Local Government Area, Delta State. Two research questions and two null hypotheses guide the study. The design for this study is a true experimental design. The population of students with low self esteem is 1286. A sample of 100 students with very low self-esteem was selected for the study, and purposive sampling technique was used in choosing two schools in the area of the study. Hare’s Self –Esteem Instrument was used for data collection. Hare self –esteem has both validity and reliability of 0.82. The study involves two groups; the experimental group and the control group. The experimental group is given cognitive behavioural therapy treatment for a period of eighth weeks and the control group is given conventional counselling for the same period of eighth weeks. Pre-test and post-test were administered to both groups. Mean scores were used in answering the three research questions and ANCOVA were used in testing the three null hypotheses at 0.05 level of significant. The finding of the study shows that cognitive behavioural therapy is effective in enhancing the students self –esteem, cognitive behavioural therapy is more effective in enhancing the female students’ self-esteem. Also there is significant difference in the effectiveness of cognitive behavioural therapy in enhancing secondary school students’ low self-esteem when compared with those in the control group. The findings were also discussed in line with the research questions and hypotheses. Recommendations were made that: the school management should organize a workshop seminar by inviting all members of the Parents Teachers Association (P.T.A) in order to sensitized them on how to enhance the self –esteem of their wards.
Nutrient dynamics in the western Canadian Arctic. II. Estimates of new and regenerated production over the Mackenzie Shelf and Cape Bathurst Polynya

Uptake of 15 N-labelled nitrate, ammonium, and urea was measured over a quasi-annual cycle in the Cape Bathurst Polynya in the Amundsen Gulf and on the Mackenzie Shelf, during the Canadian Arctic Shelf Exchange Study (CASES) in 2003 and 2004. Before the phytoplankton bloom and in autumn, nitrogen uptake was slow, representing less than 5% of annual consumption. Uptake rates increased exponentially after ice retreat and within 3 wk reached a maximum of 38.6 mmol N m ―2 d ―1 . During spring, NO 3 ― uptake supported new production of 166 mmol N m ―2 and f-ratios rose from 0.1―0.2 to 0.6―0.9. Filter fractionation showed that GF/F filters retained 93.1 ± 1.3% of the 15 N incorporated into particulate matter, suggesting that phytoplankton were responsible for the majority of the N uptake. Although free-living bacteria took up relatively more 15 N in autumn and in the lower part of the euphotic zone than phytoplankton, their assimilation of inorganic N had little effect on water column integrated f-ratios or new production. Urea supplied almost half the N assimilated by phytoplankton annually and about 80 % of the regenerated production during the spring bloom. Total new production, estimated from water column integrated 15 N-nitrogen uptake rates and linear models that interpolated rates over unsampled periods, was 342―415 mmol N m ―2 yr ―1 . Total annual N production for the region was 1.24-1.48 mol N m ―2 yr ―1 .
Analysis of Terminal Velocity and VHF Backscatter of Precipitation Particles Using Chung-Li VHF Radar Combined with Ground-Based Disdrometer

The backscatter from precipitation particles observed by the vertically pointed antenna beam of the Chung-Li VHF radar and the drop size distributions measured by a ground-based disdrometer co-located at the radar site are analyzed and studied in this article. We find that the disdrometermeasured drop size distribution can be well approximated to a Gamma distribution. On the basis of this property and a power law approximation to the fallspeed-diameter relation V D = AD B , we derive the theoretical relation between terminal velocity V D and range-corrected VHF backscatter P of the precipitation particles. We find that the V D - P relation follows a power law in the form of VD = α β P , where α and β are both the functions of the precipitation parameters. Chu et al. (1999) first found that the relation between α and β can be empirically approximated to an exponential form of α = Ae ξβ , where β is a function of B and ξ is a factor associated with precipitation. In this article, under the assumptions of the Gamma distribution of the drop size distribution and the power-law relation between VD and D, we theoretically show that the analytical relation between α and β indeed follows an exponential form of α = Ae ξβ , where ξ is a function of the drop size distribution. The experimental results obtained by the Chung-Li VHF radar combined with the ground-based disdrometer measurements validate the exponential approximation to the αβ - relation. The uses of the αβ - relation for the investigations of the rainfall rate and properties of drop size distribution are presented and discussed.
Influence of initial cell concentrations on the growth rate and biomass productivity of microalgae in domestic wastewater

The aim of this study was to compare the specific growth rate and biomass productivity of microalgae in domestic wastewater according to the initial cell concentration. The initial microalgae cell concentrations tested started from 103 cell/mL, 104 cell/mL, 105 cell/mL, 106 cell/mL, and 107 cell/mL under outdoor condition. The result revealed that the highest biomass productivity occurred at 106 cell/mL concentration with a value of 1.24 × 104 cell/mL/day, 0.26 day-1 of specific growth rate, and a doubling time of 2.63 days. Meanwhile, the lowest biomass productivity occurred at 103 cell/mL concentration with the lowest specific growth rate of 0.1 day-1 and the longest doubling time, which reached up to 7.14 day. As a result, the initial cell concentration of microalgae did influence the algal biomass productivity and growth rate differently. Thus, the maximum growth rate and biomass productivity were obtained at 106 cell/mL concentration which is recommended to be used in biotechnology industries and any wastewater treatment.
Indicative levels of PM in the ambient air in the surrounding villages of the copper smelter complex Bor, Serbia

While information on air pollution in the form of particulate matter (PM) has been monitored for longer period for EU countries, availability of PM data sets in the Western Balkan countries including the Republic of Serbia are still limited. Studies, related to the particulate pollution research, have been only carried out in the past several years. The main objective of this paper is to present PM levels measured in the ambient air in the surrounding settlements of the Copper Smelter Complex Bor. Also, one of the goals is a comparison of PM levels in the surrounding settlements with those measured in Bor town. The ambient levels of PM particles (PM10, PM2.5) were measured by automatic PM monitors at 4 nearby settlements: Slatina, Ostrelj, Krivelj and Brezonik in the time interval from 2005 to 2010. According to the measurement results, PM10 and PM2.5 levels in the ambient air were higher in the cold, heating, (October-March) than in the warm no heating period (April-September). The exceeding of the daily limit of PM10 and PM2.5 mass concentration levels was observed at all measuring points. A higher number of exceedances were detected in the cold period. The results indicate that there is a significant seasonal change in the level of fine particles at all measuring places in surroundings. In addition, the PM levels in Bor town are more influenced by the air pollution from the Copper Smelter Complex than settlements in the vicinity, where the PM concentrations were greatly influenced by the presence of domestic heating in the cold period.

A General Test of Gaming

An important lesson from the incentive literature is that explicit incentives may elicit dysfunctional and unintended responses, also known as gaming responses. The existence of these responses, however, is difficult to demonstrate in practice because this behavior is typically hidden from the researcher. We present a simple model showing that one can identify gaming by estimating the correlation between a performance measure and the true goal of the organization before and after the measure has been activated. Our hypothesis is that gaming takes place if this correlation decreases with activation. Using data from a public sector organization, we find evidence consistent with our hypothesis. We draw implications for the selection of performance measures.
MECHANICAL PROPERTIES OF SELF-COMPACTING GEOPOLYMER CONCRETE CONTAINING SPENT GARNET AS REPLACEMENT FOR FINE AGGREGATE

Millions of tons of spent garnet, a by-product of surface treatment operations, are disposed of in landfills, oceans, rivers, and quarries, among others every year, thus it causes environmental problems. The main objective of this study is to evaluate spent garnet as a sand replacement in concrete prepared with ground granulated blast furnace slag (GGBS)-based self-compacting geopolymer concrete (SCGC). Concrete mixtures containing 0%, 25%, 50%, 75% and 100% spent garnet as a replacement for river sand were prepared with a constant Liquid/Binder (L/B) mass ratio equal to 0.4. Compressive, flexural and splitting tensile strengths as well as workability tests (slump, L-box, U-box and T50) were conducted on concrete containing spent garnet. As per specification and guidelines for self-compacting concrete (EFNARC) standard, the test results showed that the concrete’s workability increased with the increase of spent garnet, while all the other strength values were consistently lower than conventional concrete (SCGC) at all stages of replacement. The results recommended that spent garnet should be used in concrete as a sand replacement up to 25% to reduce environmental problems, costs and the depletion of natural resources.
