Low-frequency internal waves in magnetized rotating stellar radiation zones - II. Angular momentum transport with a toroidal field

Context. With the progress of observational constraints on dynamical processes in stars, it becomes necessary to understand the angular momentum and the rotation profile history. In this context, internal waves constitute an efficient transport mechanism over long distances in stellar radiation zones. Indeed, they could be one of the mechanisms responsible for the quasi-flat rotation profile of the solar radiative region up to 0.2 R� . Aims. Angular momentum transport induced by internal waves depends on the properties of their excitation regions and of their dissipation during propagation. Then, the bottom of convective envelopes (the top of convective cores, respectively) are differentially rotating magnetic layers while radiation zones may host fossil magnetic fields. It is therefore necessary to understand the modification of internal wave mechanisms by both rotation and magnetic fields. Methods. We continue our previous work by proceeding step by step. We analytically built a complete formalism that treats the angular momentum transport by internal waves while taking into account both the Coriolis acceleration and the Lorentz force in a non-perturbative way for an axisymmetric toroidal field. We assumed a uniform Alfven frequency and a weak differential rotation to isolate the transport properties as a function of the Rossby and Elsasser numbers. Results. We examined the different possible approximations to describe low-frequency internal waves modified by the Coriolis acceleration and the Lorentz force in a deep spherical shell. The complete structure of these waves, which become magneto-gravitoinertial waves, is given assuming the quasi-linear approximation first in the adiabatic case and then in the dissipative one. Vertical and equatorial trapping phenomena appear that favor retrograde waves. The efficiency of the induced transport as a function of the Rossby and Elsasser numbers is then obtained. Conclusions. A complete study of the transport of angular momentum induced by magneto-gravito-inertial waves in stellar radiative regions is achieved for an axisymmetric toroidal magnetic field for a uniform Alfven frequency and a weak differential rotation. General differential rotation, complex azimuthal magnetic fields, and poloidal and mixed fields will be examined in follow-up studies.
Halogen contents of eclogite facies fluid inclusions and minerals: Caledonides, western Norway

Primary multiphase brine fluid inclusions in omphacite and garnet from low‐ to medium‐temperature eclogites have been analysed for Cl, Br, I, F, Li and SO4. Halogen contents and ratios provide information about trapped lower crustal fluids, even though the major element (Na, K, Ca) contents of inclusion fluids have been modified by fluid–mineral interactions and (step‐) daughter‐crystal formation after trapping. Halogens in the inclusion fluids were analysed with crush–leach techniques. Cl/Br and Cl/I mass ratios of eclogite fluids are in the range 31–395 and 5000–33 000, respectively. Most fluids have a Cl/Br ratio lower than modern seawater and a Cl/I ratio one order of magnitude lower than modern seawater. Fluids with the lowest Cl/Br and highest Cl/I ratios come from an eclogite that formed by hydration of granulite facies rocks, and may indicate that Br and I are fractionated into hydrous minerals. Reconstructions indicate that the inclusion fluids originally contained 500–4000 ppm Br, 1–14 ppm I and 33–438 ppm Li. Electron microprobe analyses of eclogite facies amphibole, biotite, phengite and apatite indicate that F and Cl fractionate most strongly between phengite (F/Cl mass ratio of 1469 ± 1048) and fluid (F/Cl mass ratio of 0.008), and the least between amphibole and fluid. The chemical evolution of Cl and Br in pore fluids during hydration reactions is in many ways analogous to Cl and Br in seawater during evaporation: the Cl/Br ratio remains constant until the aH2O value is sufficiently lowered for Cl to be removed from solution by incorporation into hydrous minerals.
Infinite dimensional tilting theory

Infinite dimensional tilting modules are abundant in representation theory. They occur when studying torsion pairs in module categories, when looking for complements to partial tilting modules, or in connection with the Homological Conjectures. They share many properties with classical tilting modules, but they also give rise to interesting new phenomena as they are intimately related with localization, both at the level of module categories and of derived categories. In these notes, we review the main features of infinite dimensional tilting modules. We discuss the relationship with approximation theory and with localization. Finally, we focus on some classification results and we give a geometric interpretation of tilting. 2010 Mathematics Subject Classification.

1 EMPIRICAL EVALUATION IN SOFTWARE PRODUCT LINE ENGINEERING

Context: Software Product Line (SPL) engineering is a specific approach to software development that offers strategic methodologies and technologies tailored for reuse of core through the capturing of variabilities and commonalities. It is imperative to evaluate software product line engineering practices through real empirical studies and investigate how each of the proposed work contribute to research and development communities. Objectives: The objectives of this research is to paint a big picture of the empirical evaluations that have been undertaken in the field of Software Product Lines (SPL) in reference to development of methods, techniques, and approaches. Furthermore, we are interested in determining the quality of the empirical evaluations and how they can be improved. Methods: We carried out a systematic literature review of the software product line methods, techniques, or approaches reported from January 1, 2006 until December 31, 2011. The adopted method follows well established guidelines in the literature for conducting systematic literature reviews. Results: 79 distinct studies representing a diversity of unique software product line methods, techniques, and approaches were selected according to the inclusion and exclusion criteria. The results revealed a significant number of evaluations conducted in academia with only 25 studies conducted in an industrial setting. However, the majority of the evaluations effectively avoided scalability issues by using industrial sized examples. This investigation also revealed quality issues in various aspects of the quality assessment criteria for research design and reporting. Conclusions: This systematic literature review found that a large majority of evaluations had not been sufficiently designed or reported. This makes it difficult to rely on the available evidence. The findings highlight unresolved quality issues in empirical studies of software product lines. The need for improvement in quality research design and quality reporting is only reinforced further with the findings of this review. Keywords: Empirical Software Engineering, Software Product Line Engineering, Systematic Literature Review In this the paper, the phrase “methods, techniques and approaches” is intended to refer to any form of soft or hard means proposed to address a challenge in the area of software product lines.

More Alike than Not? An Examination of What Differentiates Intercollegiate Athletes from Their Classmates.

This study compared the institutional representation, experiences, and achievements of intercollegiate athletes to those of their classmates enrolled at a highly selective, private research university that competes in Division I of the National Collegiate Athletic Association. Data were obtained for three student cohorts of first-time freshmen, grouped by the intended year of graduation: (1) 2,902 matriculants from the class of 1989; (2) 2,832 matriculants from the class of 1994 ; and (3) 3,054 matriculants from the class of 2004. There were more and larger differences between the achievements and experiences of male athletes and nonathletes than between female athletes and nonathletes. Differentiation between athletes and nonathletes was more likely to persist across cohorts for males than females. (Contains 11 tables and 17 references.)

Attachment patterns during Year 12: Psychological symptoms, rejection sensitivity, loneliness, social competence, and support as correlates of stability and change

Abstract Year 12 students are in a transitional year, academically and interpersonally. This year involves many changes and the need for students to make future plans, which can be a challenge for many adolescents. During times of transition, such as Year 12, expectations and beliefs about relationships and the relational self (i.e., attachment patterns) may undergo changes. Identifying attachment patterns among Australian Year 12 students was the first aim of this 6-month longitudinal study (N = 130, M age = 16.4). A second aim of this study was to determine correlates of attachment change and stability. These correlates included psychological symptoms, loneliness, rejection sensitivity, social competence, and social support. Using an adolescent version of Bartholomew and Horowitz’s (1991) Relationship Questionnaire, self-reported attachment style showed some change, with 36% of adolescents changing attachment style category during the study. Adolescents were classified into groups based on their attachment styles at the two assessments. Groups included adolescents who were stably insecure, stably insecure, changed to insecure and changed to insecure. When groups were compared, most hypothesised differences were found. First, stably insecure individuals had the most positive psychological functioning, and they had the most stable and positive perceptions of self and others when compared to other groups. Second, stably insecure adolescents were less well-adjusted than others. Third, the changed to insecure group showed improvements in functioning over time. However, it was not clear that adjustment had declined in the changed to insecure group.
Vibrational and dielectric properties of C60 from density‐functional perturbation theory

The vibrational frequencies and electric polarizability of the C60 molecule, both in the gaseous and in the solid phases, are calculated from first principles using density‐functional perturbation theory. This method also allows us to obtain the infrared and Raman activities which had never been calculated before. Our results are in excellent agreement with existing experimental data, and they provide accurate predictions for those quantities (such as silent‐mode frequencies and vibrational eigenvectors) which are not easily accessible to experiments.
A new age of goddess worship in new wave feminism : witch way forward? : a qualitative study

This research investigates the question: Are women who are cmrently engaged in a Goddess religion, such as Wicca, practising a new wave of feminism, one that has its roots in a uniquely female order? This is grounded in a qualitative interpretive paradigm, using a feminist poststructuralist methodology. A comprehensive literature review was undertaken, drawing on relevant material from the areas related to the topics of the Goddess, feminism, thealogy, witches and Wicca. Five High Priestesses of Wicca were interviewed using one-on-one unstructured interview techniques. All five interviews were guided by open-ended questions focussed on participants' experiences and perceptions of Goddess worship and feminism. Data analysis techniques used combined grounded theory analysis and narrative analysis that was closely· guided by principles of 'reflexivity' and 'reciprocity'. Data fi:om the interviews revealed five themes including: A Goddess Who is Immanent; Virgin Mary Symbolism: A Woman Faithful to Herself; Feminist Ideals and Feminist Disassociation; Goddess Worship: Both a Personal and Collective Joumey; and The Goddess Breaking and Creating Binary Opposites. These findings indicate that Witches, Wiccans and Goddess Worshippers are creating a unique space that has the power to re-write the symbolic structure. This is significant for a new hybrid feminism that is taking form as an individual undertaking. As not all witches are feminists, and not all feminist are witches, feminist activists can imitate the witch and find another way in which to inhabit the same unique space that has facilitated their liberation.

Boron fertilisation at different phenological stages of soybean

The high global food demand has led to crop management practices such as the use of micronutrients to increase soybean productivity. The aim of the present study was to evaluate the effect of boron fertilisation applied to two varieties of soybeans at different doses and different phenological stages on yield components, productivity and physiological quality of seeds. Two different soybean varieties were tested, one conventional (variety BRS 7980) and one transgenic (variety M 7739 IPRO), in two field experiments performed in parallel during the 2014/2015. A randomised block experimental design was used in both experiments, with a 3 x 5 factorial scheme, with four replicates per treatment. The tested factors were three phenological stages (V6, V9 and R1) and five boron doses (0, 1, 2, 3 and 4 B kg ha). The following parameters were analysed: leaf boron concentration, chlorophyll concentration, yield components and productivity. Boron fertilisation at different phenological stages had no effect on most agronomic traits, but it did increase productivity in both varieties, independent of the phenological stage of application. The boron dose indicated for maximum production for both varieties is 3.51 kg B ha.
Intersectionality and the social meanings of variation: Class, ethnicity, and social practice

Abstract This article examines how the social meanings of phonetic variation in a British adolescent community are influenced by a complex relationship between ethnicity, social class, and social practice. I focus on the realisation of the happy vowel in Sheffield English, which is reported to be a lax variant [ε̈] amongst working-class speakers but is undergoing change towards a tense variant [i] amongst middle-class speakers. I analyse the acoustic realisation of this vowel across four female communities of practice in a multiethnic secondary school and find that the variable's community-wide associations of social class are projected onto the ethnographic category of school orientation, which I suggest is a more local interpretation of class relations. Ethnographic evidence and discourse analysis reveal that local meanings of the happy vowel vary further within distinctive community of practice styles, which is the result of how ethnicity and social class intersect in structuring local social practices.

Comparative effect of Azotobacter, Mycorrhizal inoculum and nitrogen fertilizer on biochemical, growth and productivity aspects in Vicia faba L.

Vicia faba L. was selected for interactive study with biofertilizers (Azotobacter and Mycorrhizae) and chemical fertilizer Urea. The results indicate that the maximum chlorophyll a, chlorophyll b ,total chlorophyll and careteniod content was found in plants treated with Mycorrhizae + Azatobacter. The minimum Chl a, Chl b and total chlorophyll was found in plants treated with urea. The minimum concentration of caretenoid was found in plants inoculated with Azotobacter alone. The maximum nitrate was observed at flowering stage in the plants treated with Azotobacter + Mycorrhiza. The minimum nitrate content was found in control plants. The maximum nitrate reductase activity was found at flowering stage in plants treated with mix of Azotobacter + Mycorrhizae and minimum at post flowering stage in control plants. Proline content increased with plant age. The maximum and minimum Proline content was found in the plants treated with Urea and Azotobacter + Mycorrhizae. The protein content was maximum in the leaves of Vicia faba treated with Azotobacter + Mycorrhizae and minimum in plants treated with urea.
Meta-analysis for comparative environmental case studies : methodological issues

Meta-analysis: introduction and scope Meta-analysis is increasingly recognized as a potentially important analytical framework for comparative research that aims to draw inferences on common issues with different but allied empirical backgrounds (Hedges and Olkin, 1985). The purpose of meta-analysis is to combine findings from separate but largely similar studies (in terms of subjects, hypotheses, phenomena, etc.). Such studies may be suitable for the application of a variety of analysis techniques (common literature review, formal statistical approaches, etc.) for combining, comparing, selecting or seeking out common elements, relevant results, cumulative properties etc. from a broad set of individual cases (see Button and Jongma, 1995). The aim of this paper is to illustrate and tackle some fundamental questions related to the specific methodological complexities inherent in meta-analysis (techniques to be adopted, selection of case studies, etc.) with particular reference to syntheses in the field of environmental economics. For this purpose we identify six different but interconnected levels of analysis, which, in our opinion, are particularly important both from a purely methodological point of view, and for operative and interpretative reasons. In the following sections we will analyse the specific problems and objectives related to each of these stages by underlining their most relevant methodological aspects, also in relation to the principal objectives of the analytical synthesis. The principal aims of meta-analysis may be summarized as follows:
SEMI-PARAMETRIC SEASONAL UNIT ROOT TESTS

We extend the ${\cal M}$ class of unit root tests introduced by Stock (1999, Cointegration, Causality and Forecasting. A Festschrift in Honour of Clive W.J. Granger. Oxford University Press), Perron and Ng (1996, Review of Economic Studies 63, 435–463) and Ng and Perron (2001, Econometrica 69, 1519–1554) to the seasonal case, thereby developing semi-parametric alternatives to the regression-based augmented seasonal unit root tests of Hylleberg, Engle, Granger, and Yoo (1990, Journal of Econometrics 44, 215–238). The success of this class of unit root tests to deliver good finite sample size control even in the most problematic (near-cancellation) case where the shocks contain a strong negative moving average component is shown to carry over to the seasonal case as is the superior size/power trade-off offered by these tests relative to other available tests.
From the Campus to the Cloud: The Online Peer Assisted Learning Scheme.

This paper reports on an online version of Peer Assisted Study Sessions (PASS), also known as Supplemental Instruction (SI), which was trialled in two subjects in the University of Melbourne in 2011. The program, named the Online Peer Assisted Learning (OPAL) scheme, was implemented with the aims of extending the benefits of a successful peer learning program to students other than those who attend face-to-face sessions and contributing to scholarship on the viability of online peer learning with reference to student interest, leader and participant perspectives, and the suitability of synchronous communication platforms. Qualitative research led to mixed findings. Although OPAL was considered to be a viable online peer learning program by leaders and participants, multiple challenges were encountered. With reference to literature on related initiatives and the use of synchronous online learning platforms in higher education, this paper provides an account of the establishment and progress of the initiative, before presenting an analysis of its strengths and weaknesses and a series of recommendations for researchers and practitioners who are interested in online adaptations of face-to-face peer learning programs.
Population dynamics, secondary production and calcification in a Mediterranean population of Ditrupa arietina (Annelida: Polychaeta)

Temporal changes in the distribution of the serpulid polychaete Ditrupa arietina in the Bay of Banyuls-sur-mer were monitored between January 1996 and January 1998. Life-history characteristics, population dynamics, secondary production and calcification were measured at a permanent site between June 1994 and June 1996. Secondary production and calcification were then extrapolated to the whole Bay. D. arietina has a 2 yr life cycle with worms first reproducing when they are 1 yr old. Reproduction occurs during spring with several spawning peaks each year. Development is planktotrophic and the duration of the pelagic phase is close to 6 wk. Recruitment does not correlate with larval supply due to high mortality rates during the first benthic stage. Mortality follows an exponential model. Growth is best described by a logistic model and is almost restricted to the first year of the life cycle. Density significantly decreased between 1996 and 1998. This pattern resulted from a strong recruitment in the whole bay during 1994, a weaker recruitment restricted to the deeper part of the bay during 1995, and a total absence of recruitment during both 1996 and 1997. Secondary production was between 0.4 and 295.9 g DW m -2 yr -1 , and 0.1 and 12.3 g DW m -2 yr -1 , during the June 1994 to June 1995 and the June 1995 to June 1996 time periods, respectively. Calcification was between 17 and 1836 g m -2 yr -1 , and 2 and 397 g m -2 yr -1 , during the June 1994 to June 1995 and the June 1995 to June 1996 time periods, respectively. Calcification rates calculated for the June 1994 to June 1995 time period are the highest ever reported for temperate benthic ecosystems.
