The mean magnetic field modulus of Ap stars

We present new measurements of the mean magnetic eld modulus of a sample of Ap stars with spec- tral lines resolved into magnetically split components. We report the discovery of 16 new stars having this property. This brings the total number of such stars known to 42. We have performed more than 750 measurements of the mean eld modulus of 40 of these 42 stars, between May 1988 and August 1995. The best of them have an esti- mated accuracy of 25 30 G. The availability of such a large number of measurements allows us to discuss for the rst time the distribution of the eld modulus intensities. A most intriguing result is the apparent existence of a sharp cuto at the low end of this distribution, since no star with a eld modulus (averaged over the rotation pe- riod) smaller than 2.8 kG has been found in this study. For more than one third of the studied stars, enough eld determinations well distributed throughout the stellar ro- tation cycle have been achieved to allow us to characterize at least to some extent the variations of the eld modu- lus. These variations are often signicantly anharmonic, and it is not unusual for their extrema not to coincide in Send oprint requests to :G. Mathys ?

Comparative response of Zea mays (L.) genotypes to moisture stress regimes

Knowledge of the mechanisms of stress tolerance, its inheritance and efficient techniques of screening germplasms for moisture stress can facilitate utilization for crop improvement and isolating stress resilient genotypes. The present study aimed to identify the suitable donors for generating moisture stress tolerant genotypes to mitigate the problem in areas affected by water limiting conditions. Nineteen maize inbreds were evaluated under field conditions for normal irrigation and by withholding irrigation at flowering stage in split plot design with three replications during 2013-14. The results revealed that stress conditions leads to increase in days to flower but on other hand it leads to force maturity. Leaf rolling and senescence were higher in stress block as compared to normal irrigation in most of the genotypes. The genotype, CM 140 resulted in shorter anthesis silking interval (4.3 days),least leaf senescence (2.3), least yield penalty (23.3 %) with highest increase in leaf proline content under stress (2.5 fold) followed by IL 111 (4.7 days, 2.4, 23.9 %and 2.3 fold) over normal irrigation, respectively. Overall two genotypes were found to be stress tolerant, four showed moderate response and thirteen revealed susceptible response to stress. Hence, the study indicated that the identified genotypes may be used asgenetic resources for maize improvement programme in future.
Nigeria-China Trade Relations: Implication on the Nigerian Domestic Economy

The study assesses the increased trade relations between Nigeria and China with a view to providing information on its implication on the Nigerian domestic economy through the assessment of the perceptions of local manufacturers and entrepreneurs and current trade statistics between the two countries. Data were collected from both primary and secondary sources. Primary data were sourced through the administration of questionnaire on 400 randomly selected respondents. The results showed a trade imbalance in favour of China, however, Nigeria stands to gain from the China’s model of growth and manufacturing expertise. The study concluded that the Nigerian government should encourage massive direct investment and the location of production facilities in Nigeria by the Chinese firms rather than trade relations to correct the imbalance and provide more jobs for Nigerians. Keywords: Nigeria, China, Trade, Manufacturing
Impact of diurnal temperature fluctuations on larval settlement and growth of the reef coral Pocillopora damicornis

Abstract. Diurnal fluctuations in seawater temperature are ubiquitous on tropical reef flats. However, the effects of such dynamic temperature variations on the early stages of corals are poorly understood. In this study, we investigated the responses of larvae and new recruits of Pocillopora damicornis to two constant temperature treatments (29 and 31 °C) and two diurnally fluctuating treatments (28–31 and 30–33 °C with daily means of 29 and 31 °C, respectively) simulating the 3 °C diel oscillations at 3 m depth on the Luhuitou fringing reef (Sanya, China). Results showed that the thermal stress on settlement at 31 °C was almost negated by the fluctuating treatment. Further, neither elevated temperature nor temperature fluctuations caused bleaching responses in recruits, while the maximum excitation pressure over photosystem II (PSII) was reduced under fluctuating temperatures. Although early growth and development were highly stimulated at 31 °C, oscillations of 3 °C had little effects on budding and lateral growth at either mean temperature. Nevertheless, daytime encounters with the maximum temperature of 33 °C in fluctuating 31 °C elicited a notable reduction in calcification compared to constant 31 °C. These results underscore the complexity of the effects caused by diel temperature fluctuations on early stages of corals and suggest that ecologically relevant temperature variability could buffer warming stress on larval settlement and dampen the positive effects of increased temperatures on coral growth.
Assessing the length of the post-disturbance recovery period for woodland caribou habitat after fire and logging in west-central Manitoba

This study examined the habitat characteristics of areas used by woodland caribou and areas disturbed by fire or logging in the Naosap caribou range in west-central Manitoba. The population inhabiting this area is currently considered to be of high conservation concern. The purpose was to determine how long after disturbance forests again resembled caribou habitat and whether there were differences in the recovery period between fire disturbed and logged areas. Sample transects were located in areas used by caribou and areas disturbed by fire or logging. Previously, it was shown that variables positively associated with habitat suitability in this region were species composition (presence of black spruce), an index of arboreal lichen abundance and tree size, while variables negatively associated with habitat suitability were deadfall abundance and species composition (presence of trembling aspen). It was hypothesized that if disturbed sites had become suitable caribou habitat, then they should be statistically indistinguishable from sites used by caribou based on these variables. Using cluster analysis, it was found that 2 statistical clusters showed the highest level of agreement with sampling clusters, with 88% of plots used by caribou classified into one cluster, and 74% of disturbed plots classified into the other. Although a small proportion (12%) of disturbed plots resembled used plots, 30 years (the age of the oldest disturbed plot) was not enough time, in general, for forest to return to conditions resembling caribou habitat in this region.
Trauma and Treatment of Child Sexual Abuse

Children who are victims of sexual abuse not only endure trauma, but also are likely to experience negative symptomatology as a result of this horrific ordeal. This article reviews the literature on child sexual abuse and examines the most effective treatment modalities that deal with the associated trauma. This review is not comprehensive but rather provides some highlights of the current treatment outcome literature for treating childhood trauma associated with child sexual abuse.
The risk-taking channel and monetary transmission mechanism in Colombia

The recent financial crisis has brought to the forefront the need for a better understanding of the transmission mechanisms of monetary policy. The main step forward on this issue has drawn on work aimed at stressing the role of the financial sector in this transmission. Particular emphasis has been placed on how policy actions impact risk perceptions and attitudes of banks and other financial institutions, leading to shifts in the supply of credit. Along these lines, and based on evidence from Colombia, this paper finds a significant link between low interest rates and banks’ risk-taking based on evidence from Colombia. Lower interest rates raise the probability of default on new loans, but reduce that on outstanding loans. Furthermore, this channel of policy transmission depends on some bank, loan and borrower characteristics, as well as on macroeconomic conditions, such as the growth rate of the economy.
Perceptions of Afghanistan Students on the Use of Online Tools for Learning

Online technology plays a significant role in higher education especially in assisting teaching and learning. In Afghanistan, to move towards student-centered and technology- driven learning, the Ministry of Higher Education (MoHE) encourages all universities to use technology to facilitate teaching and learning. This study, therefore, attempts to measure Afghanistan university students' perceptions of online tools utilization on their learning. A survey questionnaire was distributed to 217 students, and 35 of them volunteered to be interviewed. The results generally indicated positive perceptions of online tools utilization. However, participants believed that online tools are able to assist them develop surface learning better than deep learning. This is due to a number of barriers faced by the students, and universities in providing better learning experiences through technology. The findings suggest a need for trainings and constant exposure for both teachers and students

A Rising Market and Capital Structure Decisions

This paper examines capital structure decisions in the 1990s. We test a number of capital structure theories and find notable differences between investment- and junk-grade issuers in this period. Consistent with the trade-off theory, 67% of junk-grade issues were equity as opposed to only 9% of investment-grade issues. In addition, consistent with the trade-off theory, for junk-grade issuers, we find a direct relationship between collateral and debt issuance and an inverse relationship between debt issuance and the treasury yield. However, contrary to the predictions of the trade-off theory, we do not find similar evidence for investment-grade issuers. Moreover, our analysis suggests that junk-grade issuers are concerned with the wealth-transfer consequences of choosing equity over debt; this does not seem to be the case for investment-grade issuers. We find some evidence in support of market timing and little evidence for the pecking order theory or the equity undervaluation hypothesis.
Extreme Male-biased Infections of Masked Shrews by Bladder Nematodes

Abstract Intensity of parasitic infection (number of parasites per host) can vary by date, and with host age and sex. We tested whether variation in bladder nematode (Liniscus [= Capillaria] maseri) intensity in Nova Scotian masked shrews (Sorex cinereus) was related to these variables. We collected a total of 117 shrews on 8 different sampling occasions between mid-May and mid-August. Univariate relationships suggested that intensities declined between May and August, and were higher in male shrews. In analyses simultaneously testing for relationships between intensity and date, age, and sex, the most compelling pattern was strongly male-biased parasitism.
The Decision Usefulness of Financial Accounting Measurement Concepts: Evidence from an Online Survey of Professional Investors and their Advisors

In their current framework project, the IASB and the FASB identify decision usefulness as the objective of financial reporting. Unfortunately, accounting research has neither yet come up with an undisputed measure of decision usefulness, nor with a satisfying method to rank competing measurement concepts, such as fair value or historical cost, with regard to their relative decision usefulness. Thus, assessing the decision usefulness of different accounting measurement concepts ultimately poses an empirical question. We provide evidence to this question by surveying an important user group, namely professional investors and their advisors, about their opinions on the decision usefulness of different accounting measurement concepts. We find that our respondents clearly differentiate between mark-to-market and mark-to-model fair values. While they consistently rank mark-to-market fair values as most decision-useful, they generally rank mark-to-model fair values as least decision-useful. In addition, the ranking differs across asset classes.
THE RELATION BETWEEN SCIENCE STUDENT TEACHERS’ EDUCATIONAL USE OF WEB 2.0 TECHNOLOGIES AND THEIR COMPUTER SELF-EFFICACY

The rapid increase in the use of Web 2.0 technologies has led to changes in school curricula because they are a powerful tool for developing innovative ways of teaching and learning. These technologies have also changed how teacher education programmes prepare pre-service teachers. Thus, as a predictor, pre-service teachers’ self-efficacy is important for the development of their computer skills. A descriptive research design was employed. The data were collected using a Web 2.0 technologies educational usage scale and a computer-related self-efficacy perception scale. The sample of the study involved 146 (F: 70, M: 76) student teachers in a teacher education course at Ziya Gökalp Education Faculty of Dicle University during the 2011-2012 academic year. The data were analysed using means, t-tests, and one-way ANOVAs. The study revealed that student teachers used Facebook the most frequently to communicate, access class material, hold discussions and form academic groups. Student teachers with Internet access at home used Web2.0 technologies more frequently than those without Internet access at home. The frequent use of Web 2.0 by student teachers provides teachers with the possibility for more student-centred learning activities in the classroom. Key words: science student teachers, teacher education, Web 2.0 technologies.
Public Policies and Women's Employment after Childbearing

This paper examines how the public policy environment in the United States affects work by new mothers following childbirth. We examine four types of policies that vary across states and affect the budget constraint in different ways. The policy environment has important effects, particularly for less advantaged mothers. There is a potential conflict between policies aiming to increase maternal employment and those maximizing the choices available to families with young children. However, this tradeoff is not absolute since some choice-increasing policies (generous child care subsidies and state parental leave laws) foster both choice and higher levels of employment.
Tech-Assisted Language Learning Tasks in an EFL Setting : Use of Hand phone Recording Feature

Technology with its speedy great leaps forward has undeniable impact on every aspect of our life in the new millennium. It has supplied us with different affordances almost daily or more precisely in a matter of hours. Technology and Computer seems to be a break through as for their roles in the Twenty-First century educational system. Examples are numerous, among which CALL, CMC, and Virtual learning spaces come to mind instantly. Amongst the newly developed gadgets of today are the sophisticated smart Hand phones which are far more ahead of a communication tool once designed for. Development of Hand phone as a wide-spread multi-tasking gadget has urged researchers to investigate its effect on every aspect of learning process including language learning. This study attempts to explore the effects of using cell phone audio recording feature, by Iranian EFL learners, on the development of their speaking skills. Thirty-five sophomore students were enrolled in a pre-posttest designed study. Data on their English speaking experience using audio–recording features of their Hand phones were collected. At the end of the semester, the performance of both groups, treatment and control, were observed, evaluated, and analyzed; thereafter procured qualitatively at the next phase. The quantitative outcome lent support to integrating Hand phones as part of the language learning curriculum.
Income inequality in Brazil: What has changed in recent years?

This paper provides empirical evidence to assess the impact of socioeconomic and political variables on different measures of income inequality based on the 27 units of the Brazilian federation in the period from 1999 to 2008. The Brazilian experience is a good example for understanding the income inequality policies in developing countries. The findings suggest that the improvement observed along the period under analysis is a result of the combination of increased trade openness, technological and financial development, a reduction in the unemployment rate, the adoption of social policies that imply a direct effect on the poorest families and the adoption of mechanisms against corruption.
Fat Content and Fillet Shape of Atlantic Salmon: Relevance for Processing Yield and Quality of Raw and Smoked Products

Relevance of fat content and fillet shape of Atlantic salmon for quality and yield during smoking processing was investigated. Fat content significantly influenced quality of raw and smoked products, although the interactions varied according to the raw material used and smoking temperature. In raw and smoked fillets, increasing fat content coincided with increasing L* and b*- values and decreasing fat holding capacity. In smoked salmon, fat content also correlated positively to the a*-value, smoke-intensity-/wood-fire flavor and fatty texture, and negatively to water holding capacity and shear-force. Weight loss during salting and smoking decreased with increasing fat content, and voluminous shaped fillets gave higher yield than slim fillets.
Working Paper n . 01-2016 PRODUCTIVITY DIFFERENCES BY EXPORT DESTINATION

This paper investigates differences in productivity by destination market of firms exports. The total factor productivity (TFP) is used as measure of productivity. The productivity differences by export destination are estimated using multilevel approach considering the first destination country of the firm’s exports as the second level group of the model. The analysis is based on a dataset that provides comparable cross-country data of manufacturing firms in seven European countries (Austria, France, Germany, Hungary, Italy, Spain and the United Kingdom). The results are as follows. Productivity differs from market to market and, thus, it gives support to the expectations derived from Chaney’s model (2008). The estimates confirm that non-exporters are, on average, the less productive. On the contrary, the European firms that export to China and India register the highest positive difference. A positive difference also exists for firms that export to the USA and Canada. On the contrary, there is no relevant TFP difference for firms exporting to the EU-15 area. The difference is positive but slight for the Other Asian countries and Other EU countries, while it is negative for Other areas, Other non EU countries and Central and South America. Among firm-specific characteristics only size and sector membership help to explain the productivity differences by destination market and the role of size is by far the most dominant factor.
Marketing Order Suspensions and Fresh Lemon Retail-FOB Margins

Abstract In August 1994, the Secretary of Agriculture announced the termination of the marketing order and the associated flow-to-market, or prorate, controls for fresh California and Arizona (CA/AZ) lemons. Lemon growers and handlers have expressed concern over the impact of this decision on retail-FOB margins. This study presents an econometric model of fresh lemon marketing margins that tests for the presence of buyer and seller market power during previous periods of marketing order suspension. The results show that buyer and, to a lesser extent, seller market power cause retail-FOB margins to widen during periods of prorate suspension.
Millimetre/Sub-millimetre Observations of Circumstellar Disks

Abstract TTauri disks located in nearby star-forming regions (e.g. Taurus-Auriga at 140 pc) are thought to be the site of planet formation, since proto-planetary disks orbiting around active (still accreting) TTauri stars should contain, in many cases, enough gas to form giant gaseous planets. As such, circumstellar disks are ideal laboratories to study planet formation, provided the gas and dust observations have enough sensitivity and resolving power. I will focus in these proceedings, on recent results of molecular observations which unveil the physical conditions of gas disks and reveal the weakness of our current understanding and modeling.
Spatial and temporal structure of fish assemblages in a hyperhaline coastal system: Ría Lagartos, Mexico

The spatial and temporal fish species assemblages were analyzed throughout two annual cycles (2004-2005 and 2007-2008) inthe Ria Lagartos Lagoon system, Mexico, via non-parametric multivariate analyses. We compared density and biomass of fishspecies among five habitat types defined by combinations of structure and environmental characteristics (hyperhaline, rocky,seagrass, channel, and marine), and three climatic seasons (dry, rainy, and northerlies). A total of 11,187 individuals distrib utedin 32 families and 63 species were collected. The most numerically abundant species were
