Epibiotic sponges on the hairy triton Fusitriton magellanicus in the SW Atlantic Ocean, with the description of Myxilla (Styloptilon) canepai sp. nov.

In the present study we identified a total of 26 sponge taxa, to be added to the 4 sponge species previously registered, living epizoically on Fusitriton magellanicus shells, an abun- dant and frequent gastropod in the shelf-break frontal area of the Argentine Sea, SW Atlantic Ocean. The majority of the recorded sponges were encrusting living specimens of this gastropod, the most frequent ones being Hymedesmia (Stylopus) antarctica (20%), Clathria spp. (18%), Dicty- onella spp. (13%) and Tedania spp. (9%) We described one species, Myxilla (Styloptilon) canepai sp. nov., and extended the distribution of Clathria (Microciona) antarctica and Stelodoryx cribri - gera northwards. We also registered, for the second time after its description, the species Stelo - doryx argentinae. Considering that the study area is a soft bottom and the only available substrates for settlement of sessile species are either external mineralized skeletons of living organisms, empty shells or crustacean carapaces, we conclude that shells of the gastropod F. magellanicus play a very important role for settlement of sponge species in the area. Moreover, possibly only liv- ing F. magellanicus (not the empty or pagurized shells) are important as a settlement substrate be- cause the few specimens found in empty shells could be considered as rare occurrences.
The orientation of Titan’s dayside ionosphere and its effects on Titan’s plasma interaction

A hybrid particle code has been used to examine how Titan’s interaction with Saturn’s magnetosphere is effected by the orientation of the dayside ionosphere with respect to the incident magnetospheric flow. The hybrid code self-consistently includes a version of Titan’s ionosphere represented by 7 generic ion species, over 40 ionneutral chemical reactions, ion-neutral collisions and Hall and Pederson conductivities. Emphasis is placed on what effects the orientation angle has on the ion loss rates, ion densities, and the electric and magnetic fields. The results are analyzed and regardless of the orientation angle the ionosphere is found to be within photochemical equilibrium below 1200 km altitude. The ion loss rates and field structures also show little dependence on the orientation of the dayside ionosphere. It is found to first order illumination angle does not have a significant effect on these features of the Titan interaction.
Effect of Feeding Water Soaked Rapeseed-Mustard Cake ( Brassica Juncea ) Based Diet on the Performance of Lactating Cows

The study was carried out to ascertain the effect of feeding water soaked rapeseed-mustard cake (RMC) based diet on the performance of lactating cows. Eighteen Holstein Friesian crossbred lactating cows were randomly allocated to 3 dietary treatments of 6 each viz. Control, RMC-dry and RMC-sani, respectively for an experimental period of 90 days. The glucosinolates (GLS) content of raw RMC was 149.50 µmol/g DM and it gets reduced by 31.96 per cent to 101.72 µmol/g DM in overnight water soaked (1:3 w/v ratio) RMC. The daily intake of concentrate and total DM by lactating cows did not differ significantly (P>0.05) irrespective of the dietary treatments. The digestibility coefficient (%) of DM, OM, CP, EE, NDF and ADF; nutrient density (%) and intake (g/kgW0.75) of composite diets in terms of DCP and TDN did not differ significantly (P>0.05) irrespective of dietary treatments. Milk yield and its basic quality parameters including milk fat, milk protein, total solids and SNF content were comparable among the dietary treatments. Though thiocyanate (CNS) concentration of blood serum (8.65 to 12.65 µg/ml) and milk (24.77 to 39.84 µg/ml) was significantly (P<0.01) increased in RMC fed groups as compared to control, it was significantly (P<0.01) reduced in RMC-sani as compared to RMC-dry. The serum T3 (2.07 - 2.15 nmol/L) and T4 (70.62 - 73.67 nmol/L) concentrations were comparable among the dietary treatments. Alongwith substantial reduction in the GLS content of water soaked RMC, no adverse effect could be noticed by feeding raw or water soaked RMC based diet on the performance of lactating cows and CNS excretion in the body fluids get reduced by dose dependent intake of dietary GLS.
The working conditions of the individual – in the interest of the organization? - Turnover intentions among Swedish employees

Type of thesis: Degree Project for Master in Strategic Human Resource Management and Labour Relations, 30.0 credits University: University of Gothenburg, Department for Sociology/Department of Business Administration Semester: Spring 2015 Author: Kristina Ekstrand Tutor: Stefan Schedin Title: The working conditions of the individual – in the interest of the organization? Turnover intentions among Swedish employees Background and problem: Since the 1990s, the Swedish work environment has developed towards increased demands and employees experience a decreasing amount of influence over their own work. This creates job dissatisfaction, which in turn may cause employee turnover. Voluntary turnover is usually dysfunctional and costly for the organization, involving both visible and hidden costs. The Job-Demand-Control-Support model developed by Karasek and Theorell has been used to investigate how job demands, control and social support affect wellbeing. Few studies have investigated the organizational consequences in the form of turnover intentions. Aim of study: This thesis is concerned with how job demands and control affect turnover intentions among Swedish employees. Additionally, it investigates how social support from managers, organizational commitment and satisfaction with career opportunities alter the relationship between job demands, control, and turnover intentions. It also investigates whether the willingness to exert extra effort on behalf of the organization differs depending on the individuals’ working conditions. Methodology: The analysis is based on empirical material collected by Statistics Sweden (SCB) on behalf of the Department for Sociology at the University of Gothenburg. Analysis and conclusion: This study reveals differences in turnover intention depending on the degree of job demands and control. High demands in combination with low control (‘high strain’) cause the highest turnover intention. Social support, organizational commitment, and satisfaction with career opportunities each have a buffering effect on turnover intentions in cases of ‘high strain’. Employees in ‘high strain’ situations are the second least ready to exert extra effort on behalf of the organization.
Length-weight relationship, condition factor and gonado-somatic index of Labeo calbasu (Hamilton, 1822)

An attempt was made to study dynamics of length-weight relationship (LWR), relative condition factor (Kn) and gonado-somatic index (GSI) of Labeo calbasu from the wetlands of South 24 Parganas district of West Bengal, India. A total of 275 fish specimens (130 to 430 mm) were examined over nine months from December 2006 to August 2007. Specimens were categorized into two groups based on the size at first maturity of 260 mm. The LWR was recorded W = 0.007269 L3.181 for Group A (<260 mm) and W = 0.007367 L3.031 for Group B (≥260 mm). The individuals exhibited isometric growth. The monthly mean Kn values varied from 0.924 to 1.141 with an average value of 1.059. The mean monthly values of GSI varied from 0.544 to 3.301 for male and 0.560 to 9.649 for female. There was significant variation (P < 0.05) in the mean values of GSI in different months between sexes.
Psychological capital: internal and external validity of the Psychological Capital Questionnaire (PCQ-24) on a South African sample

Orientation: Psychological capital (PsyCap) is a relatively novel construct measured with the Psychological Capital Questionnaire 24 (PCQ-24). Only one published South African study on the instrument exists, providing inconsistent psychometric results, when compared with other United States of America (USA) and non-USA studies. Research purpose: The objectives of this study were to investigate the internal validity (construct and discriminant validity), reliability and external validity (relationship with theoretically relevant variables, namely stress, burnout and work engagement) of the PCQ-24. Motivation for the study: Multiple studies have underscored the value of PsyCap within the workplace. In order to harness the full potential of the construct in the South African environment, sound measurement thereof, evidenced by a psychometrically sound instrument, is needed. Research design, approach and method: A cross-sectional survey design was used. The sample consisted of employees at managerial and non-managerial levels, from a medium-sized construction company in the Western Cape, South Africa. In addition to PsyCap, perceived stress, work-related burnout and work engagement were measured. Main findings: The results provided preliminary evidence of construct and discriminant validity, reliability and significant relations with external theoretically relevant variables. Practical/managerial implications: Researchers may confidently use the PCQ-24 to measure the construct of PsyCap and investigate relations with workplace outcomes in the South African environment, informing human relations practices. Contribution/value-add: Preliminary evidence of the psychometric properties of the PCQ-24, which measures the construct of PsyCap (consisting of hope, self-efficacy, resilience and optimism) on a South African sample, was provided in this study.
Measuring Poverty Accounting for Time

In this paper we make a methodological proposal to measure poverty accounting for time by proposing a new index that aims at reconciling the way poverty is measured in a static and a dynamic framework. Our index is able to consider the duration of the poverty spell and the social preference for equality in well-being given that, in contrast with others that have been previously proposed, it is sensitive to the level of inequality between individual complete poverty experiences over time. Moreover, other indices in the literature can be interpreted as special cases of our more general measure. An empirical illustration shows the relevance of considering the distribution of poverty experiences among the population in an international analysis.
Seasonal and interannual variability of the Eastern Tropical Pacific Fresh Pool

The Eastern Pacific Fresh Pool (EPFP) is a large region of low Sea Surface Salinity (SSS) defined by values lower than 34 practical salinity scale within [5°S-30°N, 75°W-180°W]. The fresh pool dynamically responds to strong regional and seasonally varying ocean-atmosphere-land interactions (including monsoon rain, trade and gap winds and strong currents). Using more than five years of Soil Moisture and Ocean Salinity (SMOS) satellite sea surface salinity (SSS) and complementary satellite wind, rain, currents, and sea surface temperature data together with a historical ensemble of in situ products, the present study explores the seasonal and interannual dynamics of the fresh pool over the period 2004-2015. An important interannual variability of the maximal surface extension of the EPFP over the past decade is revealed with two extreme events (2012, 2015) occurring during the SMOS satellite period. These extremes are found to be related to the El Nino-Southern Oscillation (ENSO) phases and associated anomalies of precipitation, surface currents and trade wind in the central Pacific. In 2012 (La Nina), stronger trade winds coupled with a deficit of precipitation induced a minimum extension of the pool during the rainy season. Whereas, during the strong El Nino 2014-2015, the EPFP extension reached an unprecedented maximum value. A modification of the atmospheric freshwater fluxes and ocean surface currents during winter 2014 are found to have favored the onset of this abnormal fresh event.
Assessing residency time and habitat use of juvenile smalltooth sawfish using acoustic monitoring in a nursery habitat

Highly productive, protected habitats have been shown to serve as nurseries for many marine fishes. However, few studies quantitatively measure the biotic characteristics that often drive a habitat’s function as a nursery. We used a combination of passive acoustic monitoring and quantification of biotic attributes to assess nursery habitat use of juvenile smalltooth sawfish Pristis pectinata. Acoustic receivers were deployed within Everglades National Park to quantify residency, identify the timing of emigration, and detect migration of juvenile smalltooth sawfish. Benthic grain size and organic content along with mangrove prop root density and limb overhang were quantified throughout the array to test for relationships between habitat attributes and smalltooth sawfish presence. Results indicated that sawfish moved quickly through deep water, narrow creeks, and rivers between shallow tidally influenced bays. A stepwise regression analysis of detections per hour indicated that sawfish had an increased probability of being encountered in areas with high prop root density. Observed residency within the nursery ranged from days to several months with some overwintering, which has never previously been documented in Everglades National Park. Given the large amount of individual variability of movement within the study area, future studies of juvenile smalltooth sawfish habitat in Everglades National Park should strive to investigate the relationships between occurrence and other potential drivers of habitat use such as prey fish assemblage and relative flow at multiple spatiotemporal scales.
The Spatial Study of Catholic Market in China

Land reform has always been a contentious issue in Zimbabwe mainly because of the methods used to acquire land. The land reform process began in 1979 after the signing of the Lancaster house agreement in an effort to equitably distribute land between the black and minority whites. The market based approach was used in the early phases of land reform and later on, the government led compulsory land acquisition called the Fast track land reform programme. This study was aimed at investigating the impact of the fast track land reform programme at Woodlands resettlement in Hwange, Matabeleland north province. The researcher assumed that resettlement was carried out on what was formerly a game reserve. The geography of the area does not favour crop farming. Soils are deficient in plant nutrients and rainfall is below 650mm and yet Zimbabwe land reform emphasized poverty alleviation. The study was conducted using the qualitative research approach. A case study was chosen as a research design. Questionnaires were developed and distributed to 30 respondents drawn from Woodlands resettlement using simple random sampling technique. The findings revealed that people were resettled in what was formerly a game reserve and this has resulted in human-wildlife conflict. There are mixed feelings about the impact of land reform on livelihoods at Woodlands. It is recommended that the government should step in and prioritise infrastructure development in the area. The absence of a clinic, secondary school serviced road and other social services need urgent attention as these factors are important in poverty alleviation.
STABILITY ANALYSIS TO ASCERTAIN THE PERFORMANCE OF DIFFERENT GENOTYPES OF WHEAT (TRITICUM AESTIVUM L.)

The current study aimed at ascertaining the performance of bread wheat genotypes under different environmental conditions. The stability parameters were estimated for yield and its contributing trait which exhibited homogeneous error mean square in different environments. The mean squares due to genotypes, E + (G x E), G x E and pool deviation were significant for the studied characters. This suggesting differential response of the genotypes and need to stability analysis. Results revealed that two genotypes PBW 373 and Raj 3765 had non- significant deviation from regression (S2di) for grain yield per plant. Furthermore, three crosses viz., HD 2687 x Raj 3077, DBW 17 x PBW 373 and PBW 373 x Raj 4037 showed high per se performance with below average response (bi > 1) which indicating suitability for favourable environment. Hence, above mentioned genotypes and crosses could be used to accelerate wheat improvement programmes for different cropping system
Productive characteristics of the grass Digitaria umfolozi subjected to defoliation frequencies

Foi realizado um experimento com o objetivo de avaliar a producao de materia seca, disponibilidade total de massa seca, taxa de acumulo diaria de materia seca, interceptacao luminosa, indice de area foliar, taxa de acumulo diario, disponibilidade de materia seca dos componentes morfologicos (lâmina foliar, colmo+bainha e material morto), relacao lâmina/colmo, proteina bruta, fibra em detergente neutro e fibra em detergente acido do capim Faixa-Branca submetido a sete frequencias de desfolhacao (14, 21, 28, 35, 42, 49, 56 dias). As frequencias mais longas de desfolhacao reduziram os percentuais de lâmina foliar e aumentaram colmo+bainha. A frequencia de desfolhacao influenciou positivamente a disponibilidade de lâmina foliar, colmo+bainha, material morto e materia seca total. No intervalo de 42 dias de defoliation o capim faixa branca atingiu 95% de interceptacao luminosa. Nas frequencias de 14 e 21 dias de desfolhacao os teores de proteina bruta das folhas foram acima de 20%. Verificou-se que a maior eficiencia de utilizacao do capim Faixa-Branca e alcancada quando a forrageira e manejada com intervalos de corte de 40 a 46 dias. As maiores frequencias de desfolhacao contribui positivamente para o aumento do numero de folhas totais do capim Faixa-Branca e apresentam maiores teores de proteina bruta das lâminas foliares e colmo+bainha.
Unbalanced Regressions and Spurious Inference

Spurious regression has been extensively studied in time series econometrics since Granger and Newbold’s seminal paper. Recently, it has been advanced that this phenomenon is due to a mistreatment of short-range autocorrelation in the residuals of the regression when at least one of the variables in a bivariate regression is stationary. HAC errors, feasible GLS and Cochrane-Orcutt-type procedures are then proposed to draw correct inference. Such a proposal should be cautiously considered, since nonsense inference might also be due to deterministic trend mechanisms, structural breaks, and long range dependence. In these cases, standard autocorrelation correction procedures would not solve the problem of spurious regression. We aim to make the later argument clear.
Time Domain Physical Optics for the Higher-Order FDTD Modeling in Electromagnetic Scattering from 3-D Complex and Combined Multiple Materials Objects

This paper proposes a hybrid methodology that combines an extended form of Finite-Deference Time-Domain (FDTD) method with Time Domain Physical Optics (TDPO) for analysis of 3- D scattering of combinative objects in complex electromagnetic compatibility (EMC) problems. Establishing a covariant formulation for FDTD, the extended algorithm introduces a parametric topology of accurate nonstandard schemes for the non-orthogonal div-curl problem and the suppression of lattice dispersion. For complex-combined objects including a small size (SS) and large size (LS) parts, using TDPO is an appropriate approach for coupling between two regions. Thus, our technique solves the EMC complexity with the help of higher order FDTD (HOFDTD) and the combinatory structures by using the TDPO. Numerical validation conflrms the superiority of the proposed algorithm via realistic EMC applications.
Assessment of Coral Health and Fish diversity in the Fringing Reefs of Porvenir Island and Korbisky Island, Guna Yala, Panama

Coral reefs are the most diverse and productive ecosystems on Earth, serving as important habitats to millions of organisms; however, they are disappearing at alarming rates. The major influences causing their decline are the combined effects of global climate change and increased industrialization, urbanization, and agriculture. Previous studies have correlated high coral coverage with high fish diversity; therefore, as coral reefs disappear, so too does fish diversity. This study assesses the health of the fringe reefs of Porvenir Island and Korbisky Island in Guna Yala, Panama by recording the live coral, bleached coral, diseased coral, and algae cover of each reef and recording all fish species seen within 1m to the right of the transect. Ten 15x1m belt transects were taken at the Porvenir fringe reef and set 5m apart and parallel to the shoreline, and five 15x1m belt transects were taken at the Korbisky fringe reef. There is significantly more live coral coverage in the Porvenir reef than the Korbisky reef (p=0.0213, df=223, t=-2.04); however, the Korbisky reef is more diverse (Korbisky reef: H=2.212; Porvenir reef: H=2.060). Additionally, there is no difference in the diseased coral coverage and bleached coral coverage between the two reefs (Bleached: p=0.398, df=223, t=+0.26; Diseased: p=0.0924, df=223, t=+1.33). Based on these results, we can conclude that live coral cover, diseased coral cover, and bleached coral cover do not play a role in fish diversity because the Porvenir fringe reef has more live coral coverage, but less fish diversity than the Korbisky fringe reef.
Analysis and design of numerical methods for problems arising in plasma physics

This memoir provides a summary of the author's work on the mathematical and numerical modeling of problems arising in plasma physics. It is organized in three chapters. The first one describes the semi-lagrangian and lagrangian methods developped for the approximation of transport problems to which the Vlasov equation is a particular case. The main ingredients of their analysis are presented, as well as some a priori error estimates. The approximation of the Maxwell equations by compatible methods is presented in the second chapter. After a reminder on conforming mixed finite element discretizations and their structure, we introduce the nonconforming Conga discretization and describe its main properties, in particular for the compatible approximation of the source terms. These results are then applied to the case of particle approximations for the current, and a connection is drawn with some discontinuous Galerkin methods. The third chapter finally presents the works done in the study of electrostatic plasma sheaths and in the modeling of electromagnetic wave propagation in magnetized plasmas.
OnMarginal Distributions of the Ordered Eigenvalues of Certain RandomMatrices

This paper presents a general expression for the marginal distributions of the ordered eigenvalues of certain important random matrices. The expression, given in terms of matrix determinants, is compacter in representation and more efficient in computational complexity than existing results in the literature. As an illustrative application of the new result, we then analyze the performance of the multiple-input multiple-output singular value decomposition system. Analytical expressions for the average symbol error rate and the outage probability are derived, assuming the general double-scattering fading condition.
