description: We present a machine-learning photometric redshift (ML photo-z) analysis of the Kilo-Degree Survey Data Release 3 (KiDS DR3), using two neural-network based techniques: ANNz2 and MLPQNA. Despite limited coverage of spectroscopic training sets, these ML codes provide photo-zs of quality comparable to, if not better than, those from the Bayesian Photometric Redshift (BPZ) code, at least up to zphot ≲ 0:9 and ≲ 23:5. At the bright end of r ≲ 20, where very complete spectroscopic data overlapping with KiDS are available, the performance of the ML photo-zs clearly surpasses that of BPZ, currently the primary photo-z method for KiDS. Using the Galaxy And Mass Assembly (GAMA) spectroscopic survey as calibration, we furthermore study how photo-zs improve for bright sources when photometric parameters additional to magnitudes are included in the photo-z derivation, as well as when VIKING and WISE infrared (IR) bands are added. While the fiducial four-band ugri setup gives a photo-z bias 〈δz/(1 + z)〉 = -2 × 10-4 and scatter σδz/(1+z) < 0:022 at mean 〈z〉 = 0.23, combining magnitudes, colours, and galaxy sizes reduces the scatter by ∼7% and the bias by an order of magnitude. Once the ugri and IR magnitudes are joined into 12-band photometry spanning up to 12 μm, the scatter decreases by more than 10% over the fiducial case. Finally, using the 12 bands together with optical colours and linear sizes gives 〈δz/(1 + z)〉 < 4 × 10-5 and σδz=(1+z) < 0:019. This paper also serves as a reference for two public photo-z catalogues accompanying KiDS DR3, both obtained using the ANNz2 code. The first one, of general purpose, includes all the 39 million KiDS sources with four-band ugri measurements in DR3. The second dataset, optimised for low-redshift studies such as galaxy-galaxy lensing, is limited to ≲ 20, and provides photo-zs of much better quality than in the full-depth case thanks to incorporating optical magnitudes, colours, and sizes in the GAMA-calibrated photo-z derivation.

Behaviour of clayey soils under slow repeated loading and laboratory estimation of K(0) for overconsolidated sands.

description: Repeated undrained load tests were carried out under the application of cyclic deviator stresses at a frequency that varies from 0.0001 Hz up to 0.001 Hz. For a specific amplitude of applied stress, a critical level of repeated loading (CLRL) was evaluated for both kaolinite and crust clays. The strength of the soil is affected by the frequency, cyclic fluctuation of water table, and the amount of axial strain developed during cycling. The decrease in postcyclic strength is strain-dependent. It is further shown that cycling below the CLRL causes an increase in the overconsolidation of the clayey soils. The effect of cycling in behaviour of soils increases with increasing the OCR. This thesis also describes a method for the determination of in situ horizontal stresses of heavily overconsolidated sands using a stress-path triaxial apparatus. This method was proposed by Garga and Khan (1991) who applied it for overconsolidated clays. The proposed method is based on the concept that if the radial stress exceeds the in situ horizontal stress, while maintaining the axial stress constant and equal to the in situ vertical effective stress, only then will the sample experience significant axial strain. In this investigation, the above method is applied to the samples of known stress histories of overconsolidated sand. The effect of the complex stress history undergone by soils on the estimation of K$\sb0$ by the proposed method is investigated in laboratory. It is found that the proposed method replicated the imposed "in situ" horizontal stress exactly. Also this method is capable of estimating $\rm K\sb0$ of an overconsolidated soil irrespective of the previously imposed stress history. (Abstract shortened by UMI.)
Polynomial zerofinding matrix algorithms.

Year: 1995
Subjects: subject: Computer Science.

description: In linear algebra, the eigenvalues of a matrix are equivalently defined as the zeros of its characteristic polynomial. Determining the zeros of polynomials by the computation of the eigenvalues of a corresponding companion matrix turns the table on the usual definition. In this dissertation, the work of Newbery has been expanded and a (complex) symmetric or nonsymmetric companion matrix associated with a given characteristic polynomial has been constructed. Schmeisser's technique for the construction of a tridiagonal companion matrix associated with a polynomial with real zeros has been generalized to polynomials with complex zeros. New matrix algorithms based on Schmeisser's and Fiedler's companion matrices are developed. The matrix algorithm which is based on Schmeisser's matrix uses no initial values and computes the simple and multiple zeros with high accuracy. The algorithms based on Fielder's matrices are applied recursively, and require initial values as approximations to the true zeros of the polynomial. A few techniques concerning the choice of the required initial values are also presented. An important part of this thesis is the design of a new composite three-stage matrix algorithm for finding the real and complex zeros of polynomials. The composite algorithm reduces a polynomial with multiple zeros to another polynomial with simple zeros which are then computed with high accuracy. The exact multiplicities of these zeros are then calculated by means of Lagouanelle's limiting formula. The QR algorithm has been used in all the algorithms to find the eigenvalues of the companion matrices. The effectiveness of these algorithms is illustrated by presenting numerical results based on polynomials taken from the literature and considered to be ill-conditioned, as well as random polynomials with randomly generated zeros in small and large clusters. Polynomials are represented and evaluated in quadruple precision; but it suffices to use a double precision QR algorithm in order to obtain almost double precision in the zeros of polynomials.

Element mobility during Sveconorwegian metamorphism in the Modum complex, South Norway.
Creators: name: Waque, Paul Aloysius Marc.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1996
Subjects: subject: Geochemistry.

description: The Modum complex within the Kongsberg sector of southern Norway is dominated by Early- to Mid-Proterozoic quartz-rich metasedimentary rocks that have been metamorphosed to sillimanite grade during the Kongsbergian orogeny (ca. 1500 Ma). At the onset of the Sveconorwegian (Grenvillian) metamorphism, multiple gabbroic units were emplaced at mid-crustal levels (less than 8 kbar) along north-south deformation zones. Alteration of the metagabbros to amphibolite was nonisochemical, with increases in the concentration of Na, Fe, P and high field strength elements (HFSE) (i.e. Ti, rare earth elements (REE), U, Th, Nb), and decreases in the concentration of Al, Mg, and Ca. The consistent and significant increase in HFSE is not observed in other studies of amphibolitization from southwest Scandinavia. The HFSE were either mobile and enriched or alteration to amphibolite was accompanied by a loss of mass in the order of 60%. Hornblende and scapolite in metagabbros and amphibolites contain very high concentrations of Cl (ranging from 0.76 to 2.03 wt. % and 2.85 to 3.34 wt. % for the respective minerals). Unlike the amphibolites, amphiboles or biotite in the albitized rocks do not contain abundant Cl, which may be a result of the ionized character of Cl in fluids at greenschist grade temperatures. Albitites display relative increases in the concentration of major elements Na and Si and decreases in Mg, Fe and Ca. The trace element concentrations are similar to amphibolites, with the exception of Sr and Cl, which occur at lower concentrations in the albitites. North-south trending bands of disseminated Fe-sulphides, in the order of ten metres wide, occur within the quartz-rich metasedimentary rocks of the Kongsberg sector; historically known as fahlbands. Chemical similarities between the amphibolite and the albitized rocks suggest that one evolving fluid may be responsible for both. (Abstract shortened by UMI.)

Cultural safety strategies for rural Indigenous palliative care: a scoping review
Creators: name: Schill, Kaela
name: Caxaj, Susana
Publisher: name: BioMed Central
Year: 2019

description: Background: There is little scholarship on culturally safe approaches to palliative care, especially for rural Indigenous clients. Thus, it is important to articulate how cultural safety can be enacted to support rural Indigenous Peoples and communities at end of life. We sought to identify strategies described in existing literature that have potential to deepen our understanding of culturally safe approaches to palliative care within rural and small-town settings in Canada. Methods: We searched for peer-reviewed and grey literature about Indigenous palliative care in rural and small-town settings in Canada, United States, New Zealand, and Australia. Medline, CINAHL, and Embase were searched. We thematically analyzed 22 resulting articles to address our interest in culturally safe approaches to palliative care in rural/small-town and on-reserve contexts. Results: The following themes were extracted from the literature: symbolic or small gestures; anticipating barriers to care; defer to client, family and community; shared decision-Making; active patient and family involvement; respectful, clear, and culturally appropriate communication; community ownership of services; empower cultural identity, knowledge, and traditions; and, policy. Discussion: Culturally competent practices can improve Indigenous palliative care services; however, they do not result in decolonized care. Strategies include: symbolic or small gestures; anticipating barriers to access; deferring to the client, family, and community members; and, collective decision making and family involvement. Culturally safe approaches contribute to institutional or organizational change and decolonized care. Strategies include: involvement of patient and family in service planning; reflection about individual and systemic racism; community ownership of services and; recognizing distinct Worldviews that shape care. Conclusions: Culturally safe strategies invite decolonization of care through awareness of colonialism, racism, and discrimination. They invite commitment to building partnerships, power sharing, and decision-making in the delivery of care. Culturally competent activities may catalyze the adoption of a cultural safety framework; however, mislabeling of cultural competency as cultural safety may contribute to organizational inaction and a watering down of the spirit of cultural safety.

description: We investigate the dark matter density profile of the massive elliptical galaxy, NGC 1407, by constructing spherically symmetric Jeans models of its field star and globular cluster systems. Two major challenges in such models are the degeneracy between the stellar mass and the dark matter halo profiles, and the degeneracy between the orbital anisotropy of the tracer population and the total mass causing the observed motions. We address the first issue by using new measurements of the mass-to-light ratio profile from stellar population constraints that include a radially varying initial mass function. To mitigate the mass-anisotropy degeneracy, we make use of multiple kinematic tracers, including two subpopulations of globular clusters in addition to the galaxys field stars. We create a hierarchical Bayesian model that addresses several often-neglected systematic uncertainties, such as the statistical weight given to various data sets and the adopted distance. After sampling the posterior probability distribution with a Markov chain Monte Carlo method, we find evidence for a central cusp with a log slope of γ = 1.0-0.4
 +0.2 (stat) -0.5
 0.3 (sys), with the quantified systematic uncertainty dominated by choice of anisotropy profile. This is lower than expected for dark matter halos that have undergone adiabatic contraction, supporting inferences from gravitational lensing that some process has suppressed the steepening of halos in massive galaxies. We also confirm radially biased orbits for the metal-rich globular clusters and tangentially biased orbits for the metal-poor globular clusters, which remains a puzzling finding for an accretion-dominated halo.

description: To convert tea seed shell (TSS) into bio-energy, the co-pyrolysis behaviors of TSS and waste printed circuit boards (WPCB) were studied. The impacts of synergy during co-pyrolysis were ascertained by analyzing the thermogravimetric characteristics and product properties. Blends with varying ratios of TSS and WPCB were studied using TGA for thermal decomposition analysis and a fixed-bed reactor for product analysis. According to thermal behavior analysis, the results revealed a synergistic effect when WPCB and TSS were co-pyrolysis. The dynamics of the co-pyrolysis process was confirmed using Coats–Redfern (C–R) method and the Arrhenius method. For WPCB, the values of Ea using the C–R method with the reaction orders of 1 and 1.5 were about 310.08 and 370.91 kJ/mol, respectively, while for the mixture containing 80% TSS, those values were reduced to 59.80 and 73.48 kJ/mol, respectively. To optimize the operation process, the effects of operated factors, e.g. mixing ratio, on the yields and properties of the products were fully investigated in a fixed-bed reactor. The presence of synergistic effects was further confirmed, but different results were observed for the experiments from TGA and the fixed-bed reactor. Under the optimized condition, the yields of gas, liquid, and solid products were 48.71%, 34.79%, and 16.5%, respectively.
A synthesis technique for radial line slot array antennas with isoflux radiation patterns
Creators: name: Meng, Xiangjun

Year: 2009
Subjects: subject: Engineering, Electronics and Electrical.

description: In this thesis the possibility of using radial line slot array (RLSA) antennas to provide low profile isoflux radiation patterns suitable for use as circularly-polarized tracking, telemetry & command (TT&C) antennas on low Earth orbit (LEO) satellites is investigated. The RLSA antenna elements are slot pairs located on concentric circles on the top plate of a radial waveguide. Conventional synthesis techniques cannot be used due to the fact that the RLSA antenna is a non-uniformly spaced array, the elements do not all have the same orientation, and the excitation amplitudes and phases are linked to the actual physical location of a particular slot pair. A technique is therefore developed for synthesizing such an RLSA antenna. Keywords: Antennas, Radial Line Slot Antennas, Isoflux Radiation Patterns
Longitudinal analysis of entrepreneurship and competitiveness dynamics in Latin America

description: For many countries, entrepreneurship plays a very important role like a key motor for economic growth and new job generation (Birch, 1979, 1987). Additionally entrepreneurs may contribute with innovations (products or processes) and make important contributions to market competitiveness (Acs and Audretsch, 2003). In Latin America (LA), the -micro and small entrepreneurial business- maybe are one of the most important factors for social development by the high level of job creation (or self-employment) that these kind of enterprise efforts can generate. As a field of research, entrepreneurship in LA is a relative young and rapidly expanding field of knowledge (Tiffin, 2004). Some Latin American countries have experienced a remarkable transformation in the last 20 years, both in terms of economic growth and institutional development. Export of natural resources or commodities and some low value-added processing led the economic expansion until the mid-1990s, but in the last few years the economic growth has showed variations and lower degrees of growth (Echecopar, 2004). For this reason, there is an emerging interest in opinion leaders from public administration, business, academics and general society on how to develop more value-added industries. We think that entrepreneurship and innovation are keys to overcoming this recent lack of dynamism on LA economy. In this research we investigate the relation of entrepreneurial activity and economic development and competitiveness performance of some LA countries.

description: This study employed the Life Cycle Assessment (LCA) method to evaluate the greenhouse gas (GHG) emissions of passenger vehicles across 31 provinces in China. It examined the potential of Battery Electric Vehicles (BEVs), Hybrid Electric Vehicles (HEVs), and Plug-in Hybrid Electric Vehicles (PHEVs) in significantly reducing emissions compared to Internal Combustion Engine Vehicles (ICEVs). The findings revealed that HEVs, PHEVs, and BEVs substantially lower emissions under the national average electricity GHG emissions coefficient, with PHEVs being the most effective, reducing emissions by over 30%. However, disparities exist at the provincial level due to varying electricity structures, with BEVs not fully effective in reducing emissions in about ten provinces, including Liaoning. The study further categorized provinces into six groups using the K-means method to guide the promotion of different types of New Energy Vehicles (NEVs). Sensitivity analysis highlights the critical role of reducing electricity emission coefficients and adjusting PHEV's utility factor in achieving emission reductions. The study also notes that battery replacements in PHEVs and BEVs during their lifecycle could impede emission reduction in most provinces. To maximize the environmental benefits of NEVs, there is a need to move to a greener electricity mix. At the same time, strategies for promoting NEVs should vary for different provinces.
Transparent service for IP roaming.

Subjects: subject: Engineering, Electronics and Electrical.

description: In this thesis, the requirements of mobile networking and transparent service are discussed. A survey of existing technologies for IP roaming is provided. IETF Mobile IP is the most favorable solution available today. However Mobile IP has some limitations: (a) It does not provide transparent service to mobile hosts, i.e. it requires modifications to EP stack in mobile hosts. (b) It is targeted to the wireless mobile hosts in carrier markets, which brings much unnecessary complexity for the enterprise environment, especially for semi-mobile hosts. (c) The handoff of Mobile IP introduces service disruption to IP traffic. To address the issues, a new framework and suite of protocols are proposed. The solution is termed Roaming IP. Roaming IP is targeted for roaming service in enterprise networks which have both semi and full-mobile hosts. To achieve the goals of transparency, fast handoff and simplicity, some novel ideas are used in Roaming IP: Roaming ARP, Roaming ping, Local Service Name Resolution, Roaming directory, Roaming motion detection and two-phase handoff. In the second half of the thesis, an architecture and implementation of Roaming IP is presented. Lastly, experiment results, conclusions and areas of future study are provided.

description: We investigate the properties of galaxies as they shut off star formation over the 4 billion years surrounding peak cosmic star formation. To do this, we categorize ∼7000 galaxies from 1 < z < 4 into 90 groups based on the shape of their spectral energy distributions (SEDs) and build composite SEDs with R ∼ 50 resolution. These composite SEDs show a variety of spectral shapes and also show trends in parameters such as color, mass, star formation rate, and emission-line equivalent width. Using emission-line equivalent widths and strength of the 4000 Å break, , we categorize the composite SEDs into five classes: extreme emission line, star-forming, transitioning, post-starburst, and quiescent galaxies. The transitioning population of galaxies shows modest Hα emission (EWREST ∼ 40 Å) compared to more typical star-forming composite SEDs at log10(M/M o) ∼ 10.5 (EWREST ∼ 80 Å). Together with their smaller sizes (3 kpc vs. 4 kpc) and higher Sérsic indices (2.7 vs. 1.5), this indicates that morphological changes initiate before the cessation of star formation. The transitional group shows a strong increase of over 1 dex in number density from z ∼ 3 to z ∼ 1, similar to the growth in the quiescent population, while post-starburst galaxies become rarer at z ≲ 1.5. We calculate average quenching timescales of 1.6 Gyr at z ∼ 1.5 and 0.9 Gyr at z ∼ 2.5 and conclude that a fast-quenching mechanism producing post-starbursts dominated the quenching of galaxies at early times, while a slower process has become more common since z ∼ 2.

description: This paper reports the findings of a study undertaken by the authors to investigate the ability of students in an introductory statistics subject to undertake a report writing task. It was found that students find such a task quite difficult, and generally are able to score much higher marks on questions where they carry out analyses from first principles using a standard procedure. However, it is also suggested that the report writing task may be classified as a metacognitive activity, and of itself provides a means of facilitating the development of conceptual understanding in students.

Subjects: subject: Hydrology.

description: The objectives of the study were to investigate the hydraulic, geochemical and solute or contaminant transport properties of the upper fractured zone at four Leda clay deposits in Eastern Ontario. These four sites are known as NRC, Fallowfield, Renfrew and Casselman. Physical conditions and depth of fractures of the Leda subsoil was investigated with the use of boreholes and test pits. Piezometers were installed using a conventional auger method and the double-Shelby method developed at the University of Waterloo. Hydrogeological aspects of the upper twelve metres were analyzed using water level fluctuations and variation profiles, hydraulic head and conductivity profiles. A geochemistry analysis was made by measuring the major ions and tritium concentration distribution in groundwater samples obtained from piezometers. Laboratory tests were performed on five Leda clay samples to determine the effective diffusion coefficients and the retardation factors of the major ions. The results of the study indicated that the upper portion of Leda clay deposits within Eastern Ontario are fractured and hydraulically active. Fractured Leda clay deposits less than 12 metres in depth are highly questionable on their ability to protect any underlying aquifer from surficial or buried contaminants.

description: To protect groundwater as a drinking water resource from microbiological contamination, protection zones are installed. While travelling through these zones, concentrations of potential pathogens should decline to levels that pose no risks to human health. Removal of viruses during subsurface passage is influenced by physicochemical conditions, such as oxygen concentration, which also affects virus survival. The aim of our study was to evaluate the effect of redox conditions on the removal of viruses during sand filtration. Experiments in glass columns filled with medium-grained sand were conducted to investigate virus removal in the presence and absence of dissolved oxygen. Bacteriophages MS2 and PhiX174, as surrogates for human enteric viruses were spiked in pulsed or in continuous mode and pumped through the columns at a filter velocity of about 1 m/d. Virus breakthrough curves were analyzed by calculating total viral elimination and fitted using one-dimensional transport models (CXTFIT and HYDRUS-1D). While short-term experiments with pulsed virus application showed only small differences with regard to virus removal under oxic and anoxic conditions, a long-term experiment with continuous dosing revealed a clearly lower elimination of viruses under anoxic conditions. These findings suggest that less inactivation and less adsorption of viruses in anoxic environments affect their removal. Therefore, in risk assessment studies aimed to secure drinking water resources from viral contamination and optimization of protection zones, the oxic and anoxic conditions in the subsurface should also be considered.

description: The adsorption of ionic amphiphilic diblock copolymers comprising a polycationic block, polybutadiene- block-poly(2-(dimethylamino)ethyl methacrylate) (PB-b-PDMAEMA); and its quaternized derivative (PB-b- PDMAEMAq) from aqueous media onto graphite-based surfaces was examined. Both diblock copolymers in aqueous solution form star-like micelles with a hydrophobic PB core and a cationic corona built up from either strong cationic PDMAEMAq or pH-sensitive PDMAEMA. AFM experiments show that PB-b-PDMAEMAq micelles interact slightly with a graphite surface providing films with a low surface coverage. PB-b-PDMAEMA micelles adsorbed onto a graphite surface at pH 7 result in a more homogeneous coverage of the graphite surface by the diblock copolymer. The adsorption of two enzymes, tyrosinase (Tyr) and choline oxidase (ChO) on the graphite surface premodified with these diblock copolymers was also monitored by AFM and by electrochemical measurements of the enzymatic activities of PB-b-PDMAEMA--Tyr and PB-b-PDMAEMA--ChO films. A pronounced increase in the enzymatic activity of tyrosinase was observed with the increasing concentration of PB-b-PDMAEMA micelles in solution used for their depositions. Also, a pronounced increase in the enzymatic activities of both tyrosinase and choline oxidase was observed with the increasing pH of the deposition of the micelles from 2 to 10. The enzymatic activity increases with the coverage of the graphite surface with the preadsorbed copolymer. Finally, the polymer--enzyme films were tested as biosensors for phenol (when tyrosinase was adsorbed) and choline (when choline oxidase was adsorbed) and their activity and stability were compared to already existing setups.

description: In order to determine the causes of kinematic asymmetry in the Hα gas in the SAMI (Sydney- AAO Multi-object IFS) Galaxy Survey sample, we investigate the comparative influences of environment and intrinsic properties of galaxies on perturbation. We use spatially resolved Hα velocity fields from the SAMI Galaxy Survey to quantify kinematic asymmetry (vasym) in nearby galaxies and environmental and stellar mass data from the Galaxy And Mass Assembly survey. We find that local environment, measured as distance to nearest neighbour, is inversely correlated with kinematic asymmetry for galaxies with log (M*/M⊙) > 10.0, but there is no significant correlation for galaxies with log (M*/M⊙) < 10.0. Moreover, lowmass galaxies [log (M*/M⊙) < 9.0] have greater kinematic asymmetry at all separations, suggesting a different physical source of asymmetry is important in low-mass galaxies. We propose that secular effects derived from gas fraction and gas mass may be the primary causes of asymmetry in low-mass galaxies. High gas fraction is linked to high σm/V (where σm is Hα velocity dispersion and V the rotation velocity), which is strongly correlated with vasym, and galaxies with log (M*/M⊙) < 9.0 have offset σm/V from the rest of the sample. Further, asymmetry as a fraction of dispersion decreases for galaxies with log (M*/M⊙) < 9.0. Gas mass and asymmetry are also inversely correlated in our sample. We propose that low gas masses in dwarf galaxies may lead to asymmetric distribution of gas clouds, leading to increased relative turbulence.

A programming environment for real-time multi-threaded systems.

description: In recent years, the rapid progress in the functionality, performance, and cost of VLSI technology has made multiprocessor computer platforms feasible and cost-effective. The key benefit of these platforms is their ability to offer true concurrency at the physical layer, through the replication of processor, memory and I/O facilities, and at the logical layer, through the support for multi-tasking and multi-threading. For many applications, such as those found in the real-time problem domain, the concurrent nature of these platforms bring numerous advantages. To this date however, because of the lack of real-time concurrent programming tools, delivering the potential benefits of multiprocessing directly to these applications has proven elusive. This thesis proposes the Multi-Activity Programming Environment (MAPE) which allows developers to exploit the concurrent capabilities of multiprocessor platforms while remaining consistent with the requirements of the real-time problem domain. MAPE provides a programming model and a set of supporting tools which facilitate the decomposition of an application into cooperating entities and allow for the specification of deadline-based time constraints. The MAPE components also support the allocation of the platform's resources and the modification of the application's functionality based on run-time urgency considerations.

description: Galaxy groups have been under-studied relative to their richer counterparts -- clusters. The Group Evolution Multiwavelength Study (GEMS) aims to redress some of the balance. Here we describe the GEMS sample selection and resulting sample of 60 nearby (< 130 Mpc) galaxy groups and our multiwavelength dataset of X-ray, optical, and Hi imaging. ROSAT X-ray images of each group are presented. GEMS also utilizes near-infrared imaging from the 2MASS survey and optical spectra from the 6dFGS. These observational data are complemented by mock group catalogues generated from the latest ΛCDM simulations with gas physics included. Existing GEMS publications are briefly highlighted as are future publication plans.
Marriage, migration & change in small-town Senegal
Creators: name: Teolis, Carla
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2009
Subjects: subject: Geography.

description: This paper aims to understand how the significant out-migration of men from small-town Senegal influences the marriage process and resulting conjugal life, specifically in reference to those left-behind. To address this objective, a case study approach is utilized focusing on the region of Kebemer, located in Senegal's peanut basin. Furthermore, gender theory as well as a sociology of the family approach are applied to interpret and give meaning to the different socioeconomic factors at play in shaping the dynamics of marriage and conjugal life. It is argued that while certain elements of the marriage process are experiencing changes as a result of migration (higher brideprice, a delay of first marriage, spousal selection norms and so on), it is noted that migrants tend to remain especially conservative, staying rooted in traditional beliefs and behaviours. In light of such discoveries, conventional notions of 'development' are challenged and alternative understandings sought out.

description: For the first time both Hα and far-ultraviolet (FUV) observations from an HI-selected sample are used to determine the dust-corrected star formation rate density (SFRD: ρ˙) in the local Universe. Applying the two star formation rate indicators on 294 local galaxies, we determine log(ρHα) = -1.68-0.05
 +0.13 [M⊙ yr-1 Mpc-3] and log(ρ˙FUV) = -1.71-0.13
 +0.12 [M⊙ yr-1 Mpc-3]. These values are derived from scaling Hα and FUV observations to the HI mass function. Galaxies were selected to uniformly sample the full HI mass (MHI) range of the HI Parkes All-Sky Survey (MHI ~ 107 to ~1010.7 M⊙). The approach leads to relatively larger sampling of dwarf galaxies compared to optically selected surveys. The low HI mass, low luminosity, and low surface brightness galaxy populations have, on average, lower Hα/FUV flux ratios than the remaining galaxy populations, consistent with the earlier results of Meurer. The nearidentical Hα- and FUV-derived SFRD values arise with the low Hα/FUV flux ratios of some galaxies being offset by enhanced Hα from the brightest and high mass galaxy populations. Our findings confirm the necessity to fully sample the HI mass range for a complete census of local star formation to include lower stellar mass galaxies which dominate the local Universe.
Understanding XCP: equilibrium and fairness

description: We prove that the XCP equilibrium solves a constrained max-min fairness problem by identifying it with the unique solution of a hierarchy of optimization problems, namely those solved by max-min fair allocation, but solved by XCP under an additional constraint. We describe an algorithm to compute this equilibrium and derive a lower and upper bound on link utilization. While XCP reduces to max-min allocation at a single link, in a network the additional constraint can cause a flow to receive an arbitrarily small fraction of its max-min allocation. We present simulation results to confirm our analytical findings.
