Variability in the Slope Water and its relation to the Gulf Stream path

Sea Surface Temperature (SST) and Sea Surface Height (SSH) data for 1993–2007 for the North Atlantic are combined with hydrographic data at 69W to investigate the relation between the Gulf Stream (GS) position and the Slope Water properties. SST anomalies north of the GS are correlated with changes in its path. The lag of this correlation is such that positive temperature anomalies precede northward shifts of the GS, and suggests that SST anomalies move westward with speeds of several cm/s. EOF analysis of the SST and SSH fields shows that cooling and strengthening of the SW flow are in phase over the Slope Water, which is mirrored in the vertical structure of these fields at 69W, indicating larger transports in the Deep Western Boundary Current lead to southward shifts of the mean GS path. This relation between the Slope Water and the GS path provides some predictability for the latter.
Expression of FMRP by Neurosphere Derived Cells FollowingTransplantation in the Fragile X Mouse Model

Fragile X Syndrome, characterized by intellectual impairment and learning disabilities is caused by a trinucleotide repeat expansion in the x-linked FMR1 gene leading to a complete lack of Fragile X Mental Retardation Protein (FMRP). Neural stem/progenitor cells (NSCs) cultured as floating aggregates of cells commonly referred to as neurospheres can survive, differentiate and integrate into the host environment when transplanted to the rodent CNS. Neurospheres were established from early postnatal wild-type mice and labeled with the cytoplasmic dye CFDA-SE and then stereotaxically injected as cell suspensions into the hippocampus of young adult (3-6 week old) FMR1 knockout mice. Immunocytochemical analysis of the brains revealed the presence of FMRP-expressing cells up to two weeks after transplantation. Some transplanted cells migrated within the host hippocampus and formed dendrite-like processes. A small subpopulation of the transplanted cells expressed markers of neuronal or glial phenotypes, although many cells did not stain for any of the markers that we probed. These experiments constitute an attempt to restore FMRP-expression in the brains of FMR1 knockout mice using cell suspension transplants of stem and progenitor cells.
RECOMMENDED CHANGES IN STUDENTS' INDUSTRIAL WORK EXPERIENCE SCHEME (SIWES) GEARED TOWARDS DECREASE IN UNEMPLOYMENT RATE OF BUSINESS EDUCATION GRADUATES IN NIGERIA

The high rate of unemployment of vocational education graduates in Nigeria was one of the major reasons for the introduction of Stunents' Industrial Works Experience Scheme (SIWES). Based on the high rate of unemployment, this study was undertaken to recommend the needed changes to be made in SIWES to facilitate decrease in unemployment rate of business education graduates in Nigeria. Two research questions were answered by the study, while two null hypotheses were formulated and tested. The study adopted survey research design. The population for the study was 320 respondents made up of 64 Business education lecturers, 20 staff of Industrial Training Fund (ITF) and 236 final year students. The instrument for data collection was a structured 32-item questionnaire which was validated by 3 experts. The reliability of the instrument was established using Cronbach alpha which gave a reliability coefficient of 0.87. The data collected were analyzed using mean to answer the research questions, while t-test statistic and analysis of variance (ANOVA) were used for testing the hypotheses at 0.05 level of significance. It was found among others, that re-tooling business education model offices, promulgation of a 'no rejection' of students on training policy, and ITF regulation of student's posting to iindustries of relevance, would facilitate decrease in unemployment rate of business education graduates in Nigeria. The study concludes that SIWES be modified to achieve business education graduates employability and, or self employment objective. It was recommended among others, that ITF should present a new order of studentss' placement to industries of relevance and ensuring that government policy statement regarding the establishment of SIWES is effectively implemented.
Mapping two-way continuous elastic grid on an imposed surface: Application to grid shells

This paper presents a method to generate a grid shell on an imposed shape and imposed boundary conditions. The proposed method is done by mapping a two-way continuous elastic grid on an imposed surface using an explicit dynamic finite element method. An initially flat two-way grid, with free boundary conditions, is set up over a formwork like surface that has the desired shape. Then, the grid is dropped on the fixed surface. Moreover, different strategies of formfinding are presented and a comparison with other methods is done. Finally, many examples are shown to illustrate the proposed method.
Assessing the level of cultivation and utilization of bambara groundnut (Vigna subterranea (L.) Verdc.) in the Sumbrungu community of Bolgatanga, Upper East Region, Ghana.

A study was conducted in Sumbrungu, Bolgatanga Municipality of the Upper East Region of Ghana to determine the level of cultivation and utilization of Bambara groundnut. A survey involving the use of both open-ended and close-ended questionnaires and also interviews were administered. A total of 30 Bambara groundnut farmers were selected. Houses were chosen depending on the concentration of Bambara groundnut farmers. Data was collected on the following; Sex distribution, number of acreages cultivated, household sizes, marketing and utilization, constraints in production and farmer management of the crop. Data collected were analyzed by the use of descriptive statistics; mainly percentages. It was observed that more people cultivated lower acreages of the crop; 40% of the farmers cultivated acreages of land between 1 and 2, 37% cultivated 3 and 4, 17% 5 and 6 and 6% between 7 acres and above. All (100%) farmers complained of attack of pests and diseases that destroyed the crop in the field of which they had no control measures. 17% of the farmers applied inorganic fertilizer whiles 83% did not apply any fertilizer at all. 33% of the farmers reported that they obtained yields of between 100kg-150kg/acre, whiles 7% had yield between 700kg/acre and above. The crop is used for the preparation of dishes such as ‘tubani’, ‘kose’ and snack as well as for traditional rites (funerals). 64% uses Bambara groundnut for performance of funeral rites, 33% for medicinal purposes and 3% for gifts. The study showed that constraints to Bambara groundnut production in the community are low yields, pests and disease control methods, lack of improved varieties since weevils attack stored seeds. Bambara groundnut has a lot of potential, especially in the Northern Ghana, thus, the need to research into ways of managing the crop, in terms of pests and diseases, storage methods and chemicals, so that farmers can boost its cultivation on large scale basis
Application of a self-expanding stent in the treatment of subclavian artery occlusion — a case study

Significant stenosis or complete SA subclavian artery occlusion is a relatively rare illness; it occurs in about 0.4% of the population. In 90% of cases atherosclerosis is the cause of subclavian artery (SA) occlusion or stenosis. Occlusion or hemodynamically significant stenosis (> 70%) may lead to the development of symptoms in the form of cerebral ischaemia or upper limb ischaemia. SA stenosis can be treated by both classical techniques and with the use of endovascular techniques. In connection with comparable results of the primary patency and a lower risk of the procedure itself, endovascular techniques are at present the primary treatment of SA stenosis or occlusion. In the presented paper the case of application of the MISAGO (Terumo) self-expanding stent, belonging to the new generation of peripheral self-expanding stents based on a monorail system, in the treatment of a 7 cm long lesion in the proximal left subclavian artery is presented. In the authors’ opinion, long-section lesions require the use of a flexible stent resistant to bending or deflection. The Misago (Terumo) stent can be successfully used in endovascular treatment of extra-ostial lesions of the subclavian artery.
The Dimensions of Place Meanings

This article aims to give an overview of how place meanings are created and how they influence people’s sense of belonging. It should be noted that the current literature has various shortcomings which mostly result from the lack of interdisciplinary research. The studies in place attachment usually focus on personal sense of belonging leaving aside those extending over various scales – such as, for instance, national identity. Also, place meanings and identity are primarily discussed as the very personal phenomena. On the contrary, place making and shaping is usually seen through more structural viewpoint by claiming that places mainly change in result of political or economic processes. Nowadays, there are even claims that due to the influx of globalization place no more matters and similar processes will happen everywhere. This notion does not take into account the special character of every place and the fact that outside forces come together in different ways in every place. Authors suggest that these different perspectives need to be united in order to fully grasp the character of place making and place meanings. In current articles, authors have adopted the multi-disciplinary approach and understood the place as uniting different processes starting from deeply personal meaning creation and ending with changes happening in global scale.

Space Geodesy, Potential Fields (gravity and geomagnetic) and Geomathematics

This new research sub-line, part of the Research Line/Department at Institute of Geosciences “Earth Dynamics and Earth Observation”, includes the activities of four previously existing research groups: (i) Space Geodesy,Gravimetry and Geomathematics, (ii) Palaeomagnetism, Rock Magnetism and Geomagnetic Modelling, (iii) Terrestrial and Planetary Magnetic Field and Aeronomy, and (iv)Gravimetry, Tides and Geodynamics. These four research groups, which are included on it to work together and cooperate during the next years, have been working until now independently and with very few cooperation between them. In short, it includes the study and modelling of the Earth’s (and others celestial bodies’) shape, gravity and magnetic fields, and their variations in time and space, using terrestrial and space integrated geodetic, gravimetric, geomagnetic and paleomagnetic data and advanced mathematical models and techniques.
The small genetic world of Seriatopora hystrix

The exchange of genetic information among coral reefs, through the transport of larvae, is critical to the function of Australia’s Great Barrier Reef because it influences recruitment rates and resilience to disturbance. For many species the genetic composition is not homogeneous and is determined, in part, by the character of the complex dispersal pathways that connect the populations situated on each coral reef. One method of measuring these genetic connections is to examine the microsatellite composition of individual corals and then statistically compare populations across the region. We use these connection strengths, derived from a population similarity measure, to create complex networks to describe and analyse the genetic exchange of the brooding coral, Seriatopora hystrix. The network, based on determining the putative parental origin of individual coral colonies, involved sampling 2163 colonies from 47 collection sites and examining 10 microsatellites. A dispersal network was created from the genetic distance DLR values that measure the genetic similarity of each population (defined by the local sampling effort) to every other sampled population based on the microsatellite composition. Graph theory methods show that this network exhibited infrequent long distance links and population clustering which is commonly referred to as small world topology. Comparison with a hydrodynamic based network indicates that the genetic population network topology is similar. This approach shows the genetic structure of the S. hystrix coral follows a small world pattern which supports the results derived from previous hydrodynamic modelling.
Extreme precipitation response to climate perturbations in an atmospheric mesoscale model

Observations of extreme (sub-)hourly precipitation at mid-latitudes show a large dependency on the dew point temperature often close to 14% per degree—2 times the dependency of the specific humidity on dew point temperature which is given by the Clausius–Clapeyron (CC) relation. By simulating a selection of 11 cases over the Netherlands characterized by intense showers, we investigate this behavior in the non-hydrostatic weather prediction model Harmonie at a resolution of 2.5 km. These experiments are repeated using perturbations of the atmospheric profiles of temperature and humidity: (i) using an idealized approach with a 2° warmer (colder) atmosphere assuming constant relative humidity, and (ii) using changes in temperature and humidity derived from a long climate change simulation at 2° global warming. All perturbations have a difference in the local dew point temperature compared to the reference of approximately 2°. Differences are considerable between the cases, with dependencies ranging from almost zero to an increase of 18% per degree rise of the dew point temperature. On average however, we find an increase of extreme precipitation intensity of 11% per degree for the idealized perturbation, and 9% per degree for the climate change perturbation. For the most extreme events these dependencies appear to approach a rate of 11–14% per degree, in closer agreement with the observed relation.
E-learning in an Undergraduate Course in Research Methods for the Social Sciences: Reflections on Teaching

Starting with an overview of the opportunities provided by e-learning in the educational environment, this paper discusses a blended course in social science methodology offered to around 160 students taking the undergraduate Sociology degree at the University of Salerno (Italy). In particular, it provides a reflection on ten challenges of the discipline (e.g. relationship theory and practice, quantitative vs qualitative methods) which emerged during our teaching experience and discusses how they might be addressed by adopting e-learning. To evaluate the impact of the blended course upon the experience of learner, a web survey involving 114 students is carried out. Principally, the survey focuses on the study method and the relationship between information and communication technologies (ICT) and learning. The process that we followed (reflection on the characteristics of the discipline and the needs of students, implementation of the blended course, evaluation) aims to design a valuable teaching path requiring a renewed commitment on the part of university lecturers. In this paper we argue that a blended course improved the educational process in terms of knowledge construction and reflexivity.
A Tournament Approach to Price Discovery in the U.S. Cattle Market

Abstract The dominant market where information is discovered plays the role of price leader providing substantial market information to other markets. This study investigates the dynamic relationships of 30 cattle markets across regions, cattle types, and cash/futures markets. The comparison of many markets, using an error correction model, is accomplished with the introduction of a tournament with a hierarchical cluster analysis, which allows us to conclude that the leading price for the U.S. cattle markets is discovered in the futures markets for both feeder and fed cattle.
Processes controlling the Si-isotopic composition in the Southern Ocean and application for paleoceanography

Southern Ocean biogeochemical processes have an impact on global marine primary production and global el- emental cycling, e.g. by likely controlling glacial-interglacial pCO2 variation. In this context, the natural silicon iso- topic composition ( 30 Si) of sedimentary biogenic silica has been used to reconstruct past Si-consumption:supply ra- tios in the surface waters. We present a new dataset in the Southern Ocean from a IPY-GEOTRACES transect (Bonus- GoodHope) which includes for the first time summer 30 Si signatures of suspended biogenic silica (i) for the whole wa- ter column at three stations and (ii) in the mixed layer at seven stations from the subtropical zone up to the Weddell Gyre. In general, the isotopic composition of biogenic opal exported to depth was comparable to the opal leaving the mixed layer and did not seem to be affected by any diage- netic processes during settling, even if an effect of biogenic silica dissolution cannot be ruled out in the northern part of the Weddell Gyre. We develop a mechanistic understand- ing of the processes involved in the modern Si-isotopic bal- ance, by implementing a mixed layer model. We observe that the accumulated biogenic silica (sensu Rayleigh distillation) should satisfactorily describe the 30 Si composition of bio- genic silica exported out of the mixed layer, within the limit of the current analytical precision on the 30 Si. The failures of previous models (Rayleigh and steady state) become ap- parent especially at the end of the productive period in the mixed layer, when biogenic silica production and export are low. This results from (1) a higher biogenic silica dissolu- tion:production ratio imposing a lower net fractionation fac- tor and (2) a higher Si-supply:Si-uptake ratio supplying light Si-isotopes into the mixed layer. The latter effect is especially expressed when the summer mixed layer becomes strongly Si-depleted, together with a large vertical silicic acid gradi- ent, e.g. in the Polar Front Zone and at the Polar Front.
A search for lithium in metal-poor L dwarfs

The aim of the project is to search for lithium in absorption at 6707.8 Angstroms to constrain the nature and the mass of the brightest low-metallicity L-type dwarfs (refered to as L subdwarfs) identified in large-scale surveys. We obtained low- to intermediate-resolution (R~2500-9000) optical (~560-770 nm) spectra of two mid-L subdwarfs, SDSSJ125637.13-022452.4 (SDSS1256; sdL3.5) and 2MASSJ162620.14+392519.5 (2MASS1626; sdL4) with spectrographs on the European Southern Observatory Very Large Telescope and the Gran Telescopio de Canarias. We report the presence of a feature at the nominal position of the lithium absorption doublet at 6707.8 Angstroms in the spectrum of SDSS1256, with an equivalent width of 66+/-27 Angstroms at 2.4 sigma, which we identify as arising from a CaH molecular transition based on atmosphere models. We do not see any feature at the position of the lithium feature in the spectrum of 2MASS1626. The existence of overlapping molecular absorption sets a confusion detection limit of [Li/H]=-3 for equivalently-typed L subdwarfs. We provided improved radial velocity measurements of -126+/-10 km/s and -239+/-12 km/s for SDSS1256 and 2MASS1626, respectively, as well as revised Galactic orbits. We implemented adjusting factors for the CaH molecule in combination with the NextGen atmosphere models to fit the optical spectrum of SDSS1256 in the 6200-7300 Angstroms range. We also estimate the expected Li abundance from interstellar accretion ([Li/H]=-5), place limits on circumstellar accretion (10^9 g/yr), and discuss the prospects of Li searches in cooler L and T subdwarfs.
Graph theoretic uncertainty and feasibility

We expand upon a graph theoretic set of uncertainty principles with tight bounds for difference estimators acting simultaneously in the graph domain and the frequency domain. We show that the eigenfunctions of a modified graph Laplacian and a modified normalized graph Laplacian operator dictate the upper and lower bounds for the inequalities. Finally, we establish the feasibility region of difference estimator values in $\mathbb{R}^2$.
Teaching Writing with a Web Based Collaborative Learning

Writing is known as one of the most important but difficult academic skills. It usually takes so much time for students to master competently and hence tends to be a boring lesson. At the Batam state Polytechnic, there are still many students reluctant to practice English writing and hence their writing ability is still very low. This research tried to teach writing with a web-based collaborative method to increase the students’ interest in writing activities and hence improve their writing performance. Applying a quasi-experiment method, the study implemented a purposive sample; those were two classes that took the Academic Writing Courses. One of the classes which consists of 24 students was treated as the experiment group and the other one which consists of 23 students as the control group. In the experiment class, a web forum was provided and students were asked to share their writings and to give comments or feedback (do peer editing) to their friends’ uploaded writing tasks. The web system provided accumulated mark for the quantity and the quality of those writings and comments or feedbacks. Lecturers also provided feedback before students did revising and rewriting. The control class, on the other hand, was taught with a conventional method. Both groups were compared in the development of their English writing quality by providing pretest and posttest analyzed quantitatively using SPSS. It was found that the average performance of the experiment class better than the control class.
Stock Liquidity and Stock Price Crash Risk

We find that stock liquidity increases stock price crash risk. To identify the causal effect, we use the decimalization of stock trading as an exogenous shock to liquidity. This effect is increasing in a firm’s ownership by transient investors and nonblockholders. Liquid firms have a higher likelihood of future bad earnings news releases, which are accompanied by greater selling by transient investors, but not blockholders. Our results suggest that liquidity induces managers to withhold bad news, fearing that its disclosure will lead to selling by transient investors. Eventually, accumulated bad news is released all at once, causing a crash.
Using supplementary grain to increase the marketability of culled cows.

Between 0.8 and 1.0 million female cattle are slaughtered annually in Queensland. Many of these are in very poor body condition and produce carcases with little value to the producer or to the processor. Cows from which calves have recently been weaned, and which are to be culled, are often in this category. Normally, these animals are retained on pasture to grow and finish, or are sold to keep pasture available for more valuable stock. In both cases, potential beef production and revenue are lost.
