description: Whether translating research findings for public consumption, or arguing for a policy position that reflects social work values, social workers engaged in cause advocacy need rhetorical skills. The author draws from the disciplines of linguistics, logic and communications and provides a framework for making arguments in the public arena. The structure and components of arguments are analyzed, and strategist for choosing persuasive empirical evidence and using values to support and argument are described. The use and misuses of language are discussed. Excerpts from published op-ed pieces are used for illustration.

description: The present paper deals with Bernstein polynomials and Frobenius-Euler numbers and polynomials. We apply the method of generating function and fermionic p-adic integral representation on Zp, which are exploited to derive further classes of Bernstein polynomials and Frobenius-Euler numbers and polynomials. To be more precise we summarize our results as follows, we obtain some combinatorial relations between Frobenius-Euler numbers and polynomials. Furthermore, we derive an integral representation of Bernstein polynomials of degree n on Zp . Also we deduce a fermionic p-adic integral representation of product Bernstein polynomials of different degrees n1, n2,...on Zp and show that it can be written with Frobenius-Euler numbers which yields a deeper insight into the effectiveness of this type of generalizations. Our applications possess a number of interesting properties which we state in this paper.

description: The two operations, deletion and contraction of an edge, on multigraphs directly lead to the Tutte polynomial which satisfies a universal problem. As observed by Brylawski in terms of order relations, these operations may be interpreted as a particular instance of a general theory which involves universal invariants like the Tutte polynomial, and a universal group, called the Tutte-Grothendieck group. In this contribution, Brylawski's theory is extended in two ways: first of all, the order relation is replaced by a string rewriting system, and secondly, commutativity by partial commutations (that permits a kind of interpolation between non commutativity and full commutativity). This allows us to clarify the relations between the semigroup subject to rewriting and the Tutte-Grothendieck group: the later is actually the Grothendieck group completion of the former, up to the free adjunction of a unit (this was even not mention by Brylawski), and normal forms may be seen as universal invariants. Moreover we prove that such universal constructions are also possible in case of a non convergent rewriting system, outside the scope of Brylawski's work.

description: In this paper a general van Est type isomorphism is established. The isomorphism is between the Lie algebra cohomology of a bicrossed sum Lie algebra and the Hopf cyclic cohomology of its Hopf algebra. We first prove a one to one correspondence between stable-anti-Yetter-Drinfeld (SAYD) modules over the total Lie algebra and SAYD modules over the associated Hopf algebra. In contrast to the non-general case done in our previous work, here the van Est isomorphism is found at the first level of a natural spectral sequence, rather than at the level of complexes. It is proved that the Connes-Moscovici Hopf algebras do not admit any finite dimensional SAYD modules except the unique one-dimensional one found by Connes- Moscovici in 1998. This is done by extending our techniques to work with the infinite dimensional Lie algebra of formal vector fields. At the end, the one to one correspondence is applied to construct a highly nontrivial four dimensional SAYD module over the Schwarzian Hopf algebra. We then illustrate the whole theory on this example. Finally explicit representative cocycles of the cohomology classes for this example are calculated.

A better numerical approach for finding the steady-state waiting time and the average queue length of a system for the arithmetic GI/G/1 queue
Creators: name: Bhattacharja, Bonane
Publisher: name: University of British Columbia
Year: 2011

description: In this research, an efficient numerical method is developed to determine the steady-state waiting time distribution of a GI/G/1 queue by solving the discrete-time version of Lindley’s equation, when the queue is bounded on a finite interval. Then, by using Little’s Formula, we calculate the stationary distribution for the total number of customers in the queue. The derivations are based on the Wiener-Hopf factorization of random walks. The method is carried out using a successive approximation method, by improving the weighted average. Finally, to prove the effectiveness of our method, we apply the algorithm for Uniform, Geometric, and Gamma distributions, to find an approximation. An analytical interpretation is also presented to find the waiting time distribution for the Geom/Geom/1 queue, which is not based on a finite interval, as an example of the GI/G/1 queue. Moreover, compare to the other related methods it has been proven that our method is numerically stable, simple, and robust.
Linear interference and the initiation of extratropical stratosphere-troposphere interactions
Creators: name: Kushner, Paul J.
name: Smith, Karen L.
Publisher: name: Columbia University
Year: 2012
Subjects: Atmosphere

description: Vertical fluxes of wave activity from the troposphere to the stratosphere correlate negatively with the Northern Annular Mode (NAM) index in the stratosphere and subsequently in the troposphere. Recent studies have shown that stratospheric NAM variability is also negatively correlated with the amplitude of the wave pattern coherent with the large-scale climatological stationary wavefield; when the climatological stationary wavefield is amplified or attenuated, the stratospheric jet correspondingly weakens or strengthens. Here we quantify the importance of this linear interference effect in initiating stratosphere-troposphere interactions by performing a decomposition of the vertical wave activity flux using reanalysis data. The interannual variability in vertical wave activity flux in both the Northern and Southern Hemisphere extratropics is dominated by linear interference of quasi-stationary waves during the season of strongest stratosphere-troposphere coupling. Composite analysis of anomalous vertical wave activity flux events reveals the significant role of linear interference and shows that "linear" and "nonlinear" events are essentially independent. Linear interference is the dominant contribution to the vertical wave activity flux anomalies preceding displacement stratospheric sudden warmings (SSWs) while split SSWs are preceded by nonlinear wave activity flux anomalies. Wave activity variability controls the timing of stratospheric final warmings, and this variability is shown to be dominated by linear interference, particularly in the Southern Hemisphere. The persistence of the linear interference component of the vertical wave activity flux, corresponding to persistent constructive or destructive interference between the wave-1 component of climatological stationary wave and the wave anomaly, may help improve wintertime extratropical predictability.
Tomato Cultivation and Farmers’ Knowledge on Selected Foliar Fungal Diseases in Agro Ecological Zones of Kirinyaga County, Kenya

description: Diseases are hindrance to tomato production in Kirinyaga County, Kenya. However, information on farmer’s knowledge about tomato diseases to warrant pesticide usage is scanty. Further, there is information gap on disease predisposing factor such as varietal choice and seed source. This study assessed the tomato farmers’ socio characteristic, varieties grown, seed source and knowledge of selected foliar fungal disease among tomato farmers in agro-ecological zones (AEZs) of Kirinyaga County. A cross sectional survey design that in cooperated purposive sampling and snowballing approaches was adopted in the study. Data were collected from 120 tomato farmers using structured questionnaires. A chi square (Ӽ2) test was used to examine the association between different variables at α= 0.05 using SAS version 9.4. No significant association (p > 0.05) was observed between gender of farmers and AEZ. Nonetheless, there were more men (83.33%) than women (16.67%). Terminator F1 variety was popular among farmers (25%). No significance (p > 0.05) association was observed between source of tomato planting material and AEZs. However, Agrovet was a popular seed source among farmers (40%). The reasons for choosing a particular tomato variety was significantly (p < 0.05) associated with the AEZ with 40.83% of farmers preferring tomato varieties with good marketability traits such as fruit size. Farmers’ knowledge of causative agent of early blight, late blight and Septoria leaf spot was significantly (p < 0.05) associated with AEZs. The source of farmer’s knowledge on tomato foliar fungal diseases was not significantly (p > 0.05) associated with AEZ. However, farming experiences was a popular source of knowledge (51.67%) among farmers. Inability of some farmers to identify tomato diseases negates the efforts on disease management in tomato production in Kirinyaga County. Therefore, measures such as coordinated education on tomato diseases is necessary to empower farmers on disease causes and identification to enhance disease management and improve tomato yields in Kirinyaga County in Kenya.
Demography and morphometry of an important mesopredator (black-backed jackal - Canis mesomelas) in southern Africa

description: Presented at the 9th international wildlife ranching symposium: wildlife - the key to prosperity for rural communities, held on 12-16 September 2016 at Hotel Safari & the Safari Court, Windhoek, Namibia.
description: Predation losses on livestock and wildlife ranches are more than ZAR 2 thousand million per year. The black-backed jackal Canis mesomelas is an important mesopredator in South Africa and Namibia and implicated for much of these losses. Despite control over decades, little is known about their demography and morphometry. Information was collected by farmers and specialist predator hunters during a period of 21 months. Time of year hunted (age relative to whelping), eruption of the permanent teeth and the wear of incisors were used to categorise 4 age groups: <0.5 years (pups), 0.5–1 years (juveniles), between 1–2 years (yearlings), and ≥2 years (adults). The 455 males and 411 females did not support the assumption that hunted (stressed) populations respond by producing more females to increase reproductive fitness of the species. Except for significantly more females in the age group 1-2 years (yearlings), their sex ratio was not skewed. Sexual dimorphism was evident with males weighing consistently more than same age females; the heaviest adult male and female weighed 12.5 kg and 11.5 kg, respectively. Growth and development of black-backed jackals occurred mostly in the first 6months of their lives, thereafter decreasing gradually. Sexual dimorphism was also displayed by morphometry and total body length, body length and tail length of males were consistently more than for females. Predation management of black-backed jackals must be informed by good knowledge of the interface between its biology and management; this information is now used to develop meaningful coordinated predation management strategies.

description: We propose a new method to resolve combinatorial ambiguities in hadron collider events involving two invisible particles in the final state. This method is based on the kinematic variable MT2 and on the MT2-assisted-on-shell reconstruction of invisible momenta, that are reformulated as `test' variables Ti of the correct combination against the incorrect ones. We show how the efficiency of the single Ti in providing the correct answer can be systematically improved by combining the different Ti and/or by introducing cuts on suitable, combination-insensitive kinematic variables. We illustrate our whole approach in the specific example of top anti-top production, followed by a leptonic decay of the W on both sides. However, by construction, our method is also directly applicable to many topologies of interest for new physics, in particular events producing a pair of undetected particles, that are potential dark-matter candidates. We finally emphasize that our method is apt to several generalizations, that we outline in the last sections of the paper.

An agent-based supply chain model for strategic analysis in forestry
Creators: name: Vahid, Saba
Publisher: name: University of British Columbia
Year: 2011

description: An agent-based forest sector model, CAMBIUM 2.0, is developed and applied to case studies of the forest industry in the coastal British Columbia (BC). By combining optimization and simulation, this model allows policy makers and managers to examine the impact of different supply chain (SC) configurations (e.g. establishing new facilities), and changing forest management policies (e.g. harvest restrictions). The forest sector structure and the state of the forest resources that develop over time are a result of autonomous agents interacting with each other while competing for available forest resources needed to manufacture forest products. The thesis is presented in four chapters. In chapter 1, I introduce SC modelling concepts and techniques and identify research objectives and methods. Chapter 2 presents and discusses the structure of the agent-based simulation model and the formulation of the facility location problem, presenting a novel algorithm for integrating the optimization problem with the simulation model. The model is applied to the case of a forest industry SC to establish a new agent. The predictions of the new agent about its profits are not strongly affected by higher levels of information about the cost structure of its competitors, while improving the accuracy of market predictions has a noticeable impact on such predictions. Chapter 3 evaluates the impact of establishing a log sort yard on the profitability of the forest products SC. Considering different market price scenarios, establishing a sort yard does not seem to benefit the forest products SC, mainly because of intense competition for timber. In Chapter 4, CAMBIUM 2.0 is used to investigate the impact of harvest policy changes on the SC performance and the timber supply sustainability. Alternative harvest priorities (e.g. harvesting stands with highest value first) and modifying the harvesting preference of the mills (i.e. harvesting a mix of high and low value stands) improves the timber supply sustainability with less negative economic impacts compared to lowering the harvest limit. The modelling framework developed in my research can be extended to address other research questions such as changing log export policies, setting stumpage prices, or encouraging replanting of economically desirable species.

description: We use time-resolved x-ray diffraction and magnetic optical Kerr effect to study the laser induced antiferromagnetic to ferromagnetic phase transition in FeRh. The structural response is given by the nucleation of independent ferromagnetic domains (τ_1 ~ 30ps). This is significantly faster than the magnetic response (τ_2 ~ 60ps) given by the subsequent domain realignment. X-ray diffraction shows that the two phases co-exist on short time-scales and that the phase transition is limited by the speed of sound. A nucleation model describing both the structural and magnetic dynamics is presented.

description: Spatial variability of chlorophyll, phycobiliproteins, chromophoric dissolved organic matter and variable fluorescence (Fv/Fm) was analyzed across a deep-water density front in the Southern California Current Ecosystem using an Advanced Laser Fluorometer (ALF) calibrated to assess chlorophyll concentration (Cchl), total autotrophic carbon (AC) and Synechococcus carbon biomass (SYN). Three distinct autotrophic assemblages were identified. Fluorescence was found to be three to four times higher in cooler mesotrophic waters north of the front than in warm oligotrophic waters to the south. Northern waters were distinguished by a shallow pigment maximum dominated by a blue-water type of Synechococcus and by the presence of green-water Synechococcus and cryptophytes; only blue-water Synechococcus were detected at lower concentration south of the front. The highest Cchl and AC values, accompanied by elevated Fv/Fm and chlorophyll fluorescence per unit of Cchl, and minimal Synechococcus abundance, were found directly at the front in a 20–40 m deep layer dominated by diatoms. The covariation of Fv/Fm with nitrate concentration in this layer, along with the structural changes in the phytoplankton community, suggest that it had been generated by in situ processes rather than advection. Strong structural responses to the local hydrography were also revealed by high-frequency underway ALF surface sampling, which detected an abrupt transition from low to high SYN on the northern side of a sharp salinity gradient at the front. Synechococcus-specific phycoerythrin fluorescence (FPE12) and SYN were highly correlated in surface waters (R2= 0.95), while FPE12:SYN gradually increased with depth. Strong relationships were found for chlorophyll fluorescence versus Cchl (R2= 0.95) and AC (R2= 0.79).

description: Following the idea of a field quantization of gravity as realized in group field theory, we construct a minisuperspace model where the wavefunction of canonical quantum cosmology (either Wheeler-DeWitt or loop quantum cosmology) is promoted to a field, the coordinates are minisuperspace variables, the kinetic operator is the Hamiltonian constraint operator, and the action features a nonlinear and possibly nonlocal interaction term. We discuss free-field classical solutions, the quantum propagator, and a mean-field approximation linearizing the equation of motion and augmenting the Hamiltonian constraint by an effective term mixing gravitational and matter variables. Depending on the choice of interaction, this can reproduce, for example, a cosmological constant, a scalar-field potential, or a curvature contribution.

description: Recently, Chau [Quant. Inform. & Comp. 11, 721 (2011)] showed that one can define certain metrics and pseudo-metrics on U(n), the group of all $n\times n$ unitary matrices, based on the arguments of the eigenvalues of the unitary matrices. More importantly, these metrics and pseudo-metrics have quantum information theoretical meanings. So it is instructive to study this kind of metrics and pseudo-metrics on U(n). Here we show that any symmetric norm on ${\mathbb R}^n$ induces a metric on U(n). Furthermore, using the same technique, we prove an inequality concerning the eigenvalues of a product of two unitary matrices which generalizes a few inequalities obtained earlier by Chau [arXiv:1006.3614v1].

description: Over 30 years ago, the U.S. Supreme Court granted welfare clients the right to an administrative hearing before the termination of their benefits. Fair hearings have since become a mainstay of the welfare bureaucracy, but there has been scant empirical research on them, particularly since welfare reform, which eliminated the entitlement status of welfare while emphasizing clients' obligations. This article reports on an empirical study of the fair hearing systems in New York, Wisconsin, and Texas. The findings indicate that fair hearings are rarely used but frequently successful. This article explores why clients so infrequently rely on fair hearings.

description: The heavy fermion system CeNi9Ge4 exhibits a paramagnetic ground state with remarkable features such as: a record value of the electronic specific heat coefficient in systems with a paramagnetic ground state, γ= C/T \simeq 5.5 J/molK^2 at 80 mK, a temperature-dependent Sommerfeld-Wilson ratio, R=χ/γ, below 1 K and an approximate single ion scaling of the 4f-magnetic specific heat and susceptibility. These features are related to a rather small Kondo energy scale of a few Kelvin in combination with a quasi-quartet crystal field ground state. Tuning the system towards long range magnetic order is accomplished by replacing a few at.% of Ni by Cu or Co. Specific heat, susceptibility and resistivity studies reveal T_N \sim 0.2 K for CeNi8CuGe4 and T_N \sim 1 K for CeNi8CoGe4. To gain insight whether the transition from the paramagnetic NFL state to the magnetically ordered ground state is connected with a heavy fermion quantum critical point we performed specific heat and ac susceptibility studies and utilized the μSR technique and quasi-elastic neutron scattering.

description: CO2 capture and storage (CCS) has the potential to develop into an important tool to address climate change. Given society’s present reliance on fossil fuels, widespread adoption of CCS appears indispensable for meeting stringent climate targets. We argue that for conventional CCS to become a successful climate mitigation technology—which by necessity has to operate on a large scale—it may need to be complemented with air capture, removing CO2 directly from the atmosphere. Air capture of CO2 could act as insurance against CO2 leaking from storage and furthermore may provide an option for dealing with emissions from mobile dispersed sources such as automobiles and airplanes.

description: The African lion (Panthera leo) is listed as "vulnerable" by the IUCN Red List, mainly threatened by indiscriminate killing, primarily as a result of retaliatory or pre-emptive killing to protect human life and livestock, and prey base depletion. Habitat loss and conversion has led to a number of subpopulations becoming small and isolated. With the weakened connectivity between the main strongholds, genetic drift and loss of genetic diversity could affect the genetic health of the species. In the present study, we investigated the evolutionary history of the species at different scales of time and space. A total of 182 samples were used, including a larger number of 77 samples from Tanzanian protected areas. The mitochondrial cytochrome b gene was sequenced and the specimens were genotyped for 11 microsatellites and more than 9,000 SNPs. The preliminary results indicate that the lion is structured into two lineages at the continental scale (West-Central vs South-Eastern), a pattern observed within many other large African savanna species displaying large distribution ranges. Pleistocene climatic oscillations and biogeographical barriers were proposed as the main factors to have driven the lineage sorting. The first results based on microsatellites highlighted that the Tanzanian population displayed good level of genetic diversities with no signs of inbreeding. Indication of isolation-by-distance nevertheless highlighted a potential future impact of fragmentation on the population genetic health. SNPs allowed to identify 3 populations of lions in Tanzania, geographically structured. Using various molecular markers, the present work will further explore the taxonomy and the evolutionary history of the African lion for bringing insights in its conservation requirements.

description: Population and insemination studies indicate that women experience declining fertility with ageing. The question therefore arises whether older women are suitable oocyte donors. This study addresses this issue by examining the relationship between oocyte donor age and clinical outcome in a large oocyte donation programme. We retrospectively reviewed data from 458 consecutive oocyte donation cycles completed by 164 different designated oocyte donors. Data were divided into two groups: group A, cycles with donors aged 21–30 years at the time of follicular aspiration (193 cycles, 88 donors); and group B, cycles with donors aged 31–40 years at the time of follicular aspiration (265 cycles, 86 donors). Five donors, because of ageing during repetitive donations, contributed data to groups A and B. In a given cycle, all oocytes for a recipient came from only one designated donor. Comparing the two donor groups, there was no difference in the amount of gonadotrophin used to achieve optimal stimulation; however, more oocytes were obtained from group A than group B donors (16.8 ± 6.9 and 15.1 ± 8.1 respectively, P < 0.05). Similar percentages of oocytes were fertilized in each group, resulting in the transfer of comparable numbers of embryos (4.5 ± 1.1 and 4.4 ± 13 respectively). Comparable clinical pregnancy rates were achieved (group A, 36%; group B, 37%). The spontaneous abortion rates were also similar (group A, 20%; group B, 12%), resulting in comparable ongoing and delivered pregnancy rates per cycle (group A, 29%; group B, 32%) and per embryo transferred (group A, 6.4%; group B, 7.3%). In conclusion, women of proven fertility should not be excluded from donating oocytes simply because of their age. There exists a cohort of fertile women who resist the decreasing fecundity and increasing spontaneous abortion rates associated with ageing. With careful screening, many women of proven fertility can donate oocytes until the age of 40 years with an efficacy equal to that of younger women. Given the relative shortage of suitable oocyte donors, and increasing requests from recipients with previous donor oocyte babies to obtain oocytes from the same, now older, donor, the findings of this study are of practical clinical importance.

description: Atmospheric low-frequency variability (LFV) is studied in a two-layer quasigeostrophic model. The model geometry is a periodic β channel with flat bottom and zonally inhomogeneous thermal forcing. As a result of the idealized land–sea contrast, the model produces a zonally modulated climatological jet with realistic amplitude. The model's LFV is equivalent barotropic; principal component analysis reveals that it consists of (i) dominant stationary patterns with red-noise-like temporal behavior and (ii) propagating waves with periods of 37 and 50 days superimposed on the former. The vorticity forcing due to synoptic eddies is dominated by self-interaction of high-pass filtered model fields. Applying a phase-randomized, stochastic analog of this forcing to a version of the full model in which fast baroclinic instability and, therefore, synoptic eddies are suppressed, produces a climatology and LFV that are very similar to those in the full model. Synoptic eddies are solely represented in the simplified model version by means of stochastic forcing that is independent of the low-frequency flow. It follows that, while fast synoptic eddies are modulated in the full model by the LFV, this modulation is fairly passive: anomalous generation of the synoptic eddies in the course of the full system's low-frequency evolution, the so-called synoptic-eddy feedback, is not essential in selecting the system's low-frequency modes; the main role of synoptic eddies is to supply energy to these modes. Further analysis indicates that the LFV in this thermally driven model originates from the barotropic mode's dynamics. The baroclinic mode passively follows, to first order, the low-frequency changes in the barotropic mode. The latter changes are due to stochastically excited, weakly damped linear eigenmodes of the barotropic-mode equation. Two distinct stationary eigenmodes, as well as two pairs of propagating modes with periods of 27 and 36 days, respectively, dominate the low-frequency behavior. The leading empirical orthogonal functions in this model are associated with these six particular eigenmodes. The latter are not well separated, however, from the other eigenmodes in terms of damping time scale, and it is the barotropic nonlinearity that selects the six dynamically important modes over the others. Interactions between these six modes also result in the occurrence of probability density maxima in two-dimensional subspaces of the model's phase space.

Publisher: name: Columbia University
Year: 1990
Subjects: Public policy (Law)

description: The failure to coordinate policy formulation with policy implementation in hazardous waste regulation has hindered the identification of potential obstacles to achieving compliance. In an effort to integrate policy formulation with implementation, this paper develops a strategic regulatory planning model and applies it to a specific case, the underground storage tank provision of the 1984 Hazardous and Solid Waste Amendments. The final plan, submitted to the United States Environmental Protection Agency, emphasises 'induced compliance'. The study shows that the model provides policymakers with a practical tool for combining policy formulation with implementation and identifying possible impediments to achieving compliance.
Personality disorder traits and antisocial behaviour in adolescents

description: In an effort to further understand the contribution of maladaptive personality characteristics to the expression of distinct forms of antisocial behaviour during adolescence, this study examined links between personality disorder traits, physical and social aggression, and nonaggressive antisocial behaviour over one year. A community sample of adolescents (n=182) completed self-reports of physical and social aggression and nonaggressive antisocial behaviour during the summer between the 10th and 11th grades. Participants’ parents (n=192) completed a measure assessing the adolescents’ personality disorder traits when the youths were 15 years of age in 2009, and their teachers (n=154) completed measures of the frequency of adolescents’ perpetration of physical and social aggression during the following academic year. Analyses, conducted separately for boys and girls, explored the links between broad personality disorder factors and facet-level traits as predictors of teacher- and self-rated physical and social aggression, and nonaggressive antisocial behaviour. Results of a series of multiple regression analyses revealed that disagreeableness emerged as a strong predictor of teacher-rated social aggression, self-rated physical aggression and nonaggressive antisocial behaviour in girls but not boys. Broad personality disorder traits did not predict self-rated social aggression. Findings from the facet level revealed that, in contrast with previous research, associations were not found between aspects of disagreeableness, emotional instability, compulsivity and nonaggressive antisocial behaviour in boys. Further, facets within the introversion factor strongly predicted self-rated physical and teacher-rated social aggression for girls only. Findings highlight the importance of examining both higher- and lower-order maladaptive personality traits and considering gender differences in trait expression, in understanding the perpetration of distinct forms of adolescent antisocial behaviour.
