AN INSTITUTIONAL ECONOMIC APPRAISAL OF WORKER EQUITY SCHEMES IN AGRICULTURE:
Creators: name: Karaan, Mohammad

Publisher: name: Unknown
Year: 2003
Subjects: Labor and Human Capital

description: The institutional economic appraisal conducted in this paper confirms that equity schemes are subject to institutional incompleteness as proposed in ICT. The incompleteness stem from the lack of verifiability related to social capital, embeddedness, governance and micro performance. In addition, they lack the requisite ex ante incentives to enable ex post adaptation, counterveilance over opportunism, and the distribution of residual claims and control. The first reason for incompleteness emanate from the motivations of the initiators, which is opportunism by landowners to secure their assets in the face of uncertainty and/or enhance their returns in the marketplace. The lack of worker effort and options in the early stages raises credible commitment questions. Examining the governance aspects of equity schemes reveal that they are consistent with modern trends to separate ownership and control. However, a key concern is the asymmetry in human capital and subsequently in power, residual control, gratification, and ultimately economic empowerment. The analysis is aimed at identifying the incentives and innovations required to make equity schemes, as a type of shareholder contract, more complete and credible in an empowerment context. Recommendations towards institutional innovation are offered.

description: Le vieillissement de la population mondiale est en cours, il est inéluctable, y compris dans les pays du Sud. S’il est d’une temporalité lente, il n’en demeure pas moins qu’il consiste en une véritable révolution démographique qui entraînera dans son sillage tout au long du 21e siècle de profondes transformations sociales, économiques ou culturelles. Cependant, l’hétérogénéité des niveaux de développement des pays ainsi que du rythme des processus de vieillissement démographique est suffisamment importante pour que ses conséquences ne soient pas les mêmes ni de la même ampleur dans tous les pays. C’est cette diversité de situations qui sera passée en revue ici, avec un zoom particulier sur les pays du Sud.

Non-Minimally Coupled Einstein Gauss Bonnet Inflation Phenomenology in View of GW170817

description: We study the inflationary phenomenology of a non-minimally coupled Einstein Gauss-Bonnet gravity theory, in the presence of a scalar potential, under the condition that the gravitational wave speed of the primordial gravitational waves is equal to unity, that is $c_T^2=1$, in natural units. The equations of motion, which are derived directly from the gravitational action, form a system of differential equations with respect to Hubble's parameter and the inflaton field which are very complicated and cannot be solved analytically, even in the minimal coupling case. In this paper, we present a variety of different approximations which could be used, along with the constraint $c_T^2=1$, in order to produce an inflationary phenomenology compatible with recent observations. All the different approaches are able to lead to viable results if the model coupling functions obey simple relations, however, different approaches contain different approximations which must be obeyed during the first horizon crossing, in order for the model to be rendered correct. Models which may lead to a non-viable phenomenology are presented as well in order to understand better the inner framework of this theory. Furthermore, since the velocity of the gravitational waves is set equal to $c_T^2=1$, as stated by the striking event of GW170817 recently, the non-minimal coupling function, the Gauss-Bonnet scalar coupling and the scalar potential are related to each other. Here, we shall assume no particular form of the scalar potential and we choose freely the scalar functions coupled to the Ricci scalar and the Gauss-Bonnet invariant. Certain models are also studied in order to assess the phenomenological validity of the theory, but we need to note that all approximations must hold true in order for a particular model to be valid.

description: Maximal ancestral graphs (MAGs) have many desirable properties; in particular they can fully describe conditional independences from directed acyclic graphs (DAGs) in the presence of latent and selection variables. However, different MAGs may encode the same conditional independences, and are said to be \emph{Markov equivalent}. Thus identifying necessary and sufficient conditions for equivalence is essential for structure learning. Several criteria for this already exist, but in this paper we give a new non-parametric characterization in terms of the heads and tails that arise in the parameterization for discrete models. We also provide a polynomial time algorithm ($O(ne^{2})$, where $n$ and $e$ are the number of vertices and edges respectively) to verify equivalence. Moreover, we extend our criterion to ADMGs and summary graphs and propose an algorithm that converts an ADMG or summary graph to an equivalent MAG in polynomial time ($O(n^{2}e)$). Hence by combining both algorithms, we can also verify equivalence between two summary graphs or ADMGs.

Role of immunoregulation in the development of dermal fibrosis in tight-skin mice
Creators: name: Wong, Connie
Publisher: name: University of British Columbia
Year: 2009

description: The tight-skin (Tsk/+) mutant mouse serves as an experimental model for human scleroderma, a connective tissue disorder characterized by excessive deposition of collagen and other extracellular matrix molecules predominantly within the dermal regions, leading to the development of fibrosis. The pathogenesis underlying this disease is currently unclear; however, cells of the immune system have been proposed to be involved in the regulation of fibrosis in both mouse and man. Thus, the potential contribution of immunoregulatory factors in disease development were examined using the Tsk/+ model. These studies identified a crucial role for CD4+ T-helper 2 (Th2) cells in regulating the development of dermal fibrosis in the Tsk/+ mutant mice. The ability of CD4+ Th2-cell derived cytokines, in particular IL-4, to modulate dermal collagen deposition in Tsk/+ mice was demonstrated using in vitro and in vivo approaches. Specifically, inhibiting IL-4, a Th2 cell-derived cytokine and a requisite factor in the induction CD4+ Th2 cell differentiation, prevented the development of dermal fibrosis in Tsk/+ mice. These studies suggested a pivotal role for Th2 cells and/or Th2-derived EL-4 in the Tsk/+ disease process. Furthermore, augmentatation of CD4+ Th2 responses, via deletion of the genes for either IL-12 or IFN-y, increased dermal collagen deposition within Tsk/+ mice, also supporting a model in which CD4+ Th2 cell activity is required for dermal pathology in these mice. Moreover, the emergence of a Th2 immune response apparently required for dermal fibrosis in Tsk/+ mice appears to require the contribution of yδ T cells as the absence of these cells prevented the evolution of the Tsk/+ dermal fibrosis. These studies will help to provide a framework in understanding the role of Th cells in the development of the fibrotic disease in Tsk/+ mice, with potential relevance to human scleroderma.

description: The Min system in Escherichia coli directs division to the centre of the cell through pole-to-pole oscillations of the MinCDE proteins. We present a one dimensional stochastic model of these oscillations which incorporates membrane polymerisation of MinD into linear chains. This model reproduces much of the observed phenomenology of the Min system, including pole-to-pole oscillations of the Min proteins. We then apply this model to investigate the Min system during cell division. Oscillations continue initially unaffected by the closing septum, before cutting off rapidly. The fractions of Min proteins in the daughter cells vary widely, from 50%-50% up to 85%-15% of the total from the parent cell, suggesting that there may be another mechanism for regulating these levels in vivo.

description: It has been observed that binary Kuiper Belt Objects (KBOs) exist contrary to theoretical expectations. Their creation presents problems to most current models. However, the inclusion of a third body (for example, one of the outer planets) may provide the conditions necessary for the formation of these objects. The presence of a third massive body not only helps to clear the primordial Kuiper Belt but can also result in long lived binary Kuiper belt objects. The gravitational interaction between the KBOs and the third body causes one of four effects; scattering into the Oort cloud, collisions with the growing protoplanets, formation of binary pairs, or creation of a single Kuiper belt object. Additionally, the initial location of the progenitors of the Kuiper belt objects also has a significant effect on binary formation.

description: We propose a method to generate stabilized radio-frequency polarization modulation based on optical frequency combs. Two pulse trains with the same repetition rate and different offset frequencies generate arbitrary polarization states that are modulated at the offset frequency difference. Long-term stability of the polarization modulation is demonstrated with the modulation frequency at frep/2. Modulation at frep/4 is also demonstrated to show the flexibility of the technique. We employ an electrical delay line to fine-tune the polarization states that constitute the time-dependent modulation.

description: Nonparametric and parametric demand analyses are used to investigate the structural changes in egg consumption in Canada over the period 1978:1-2001:4. The nonparametric empirical results show that Canadian egg demand has undergone structural change, consistent with news coverage of egg-cholesterol nutrition issues, introduction of new products into the market, popularization of Atkin's diet and other variables. The results from the parametric method revealed that the impacts of advertising and media information index are significant and time varying. Furthermore, the media information index is found to have a significant effect on the size of advertising elasticities. With a larger number of positive media articles, the bigger the impact of shell egg advertising. The results of this study provide important information for policy makers and producers, processors in the egg industry.

description: We report the parallax and proper motion of millisecond pulsar J0030+0451, one of thirteen known isolated millisecond pulsars in the disk of the Galaxy. We obtained more than 6 years of monthly data from the 305 m Arecibo telescope at 430 MHz and 1410 MHz. We measure the parallax of PSR J0030+0451 to be 3.3 +/- 0.9 mas, corresponding to a distance of 300 +/- 90 pc. The Cordes and Lazio (2002) model of galactic electron distribution yields a dispersion measure derived distance of 317 pc which agrees with our measurement. We place the pulsar's transverse space velocity in the range of 8 to 17 km/s, making this pulsar one of the slowest known. We perform a brief census of velocities of isolated versus binary millisecond pulsars. We find the velocities of the two populations are indistinguishable. However, the scale height of the binary population is twice that of the isolated population and the luminosity functions of the two populations are different. We suggest that the scale height difference may be an artifact of the luminosity difference.

description: Many prior studies have found a gender gap between male and female students' performance on conceptual assessments such as the Force Concept Inventory (FCI) and the Conceptual Survey of Electricity and Magnetism (CSEM) with male students performing better than female students. Prior studies have also found that activation of a negative stereotype about a group or stereotype threat, e.g., asking test-takers to indicate their ethnicity before taking a test, can lead to deteriorated performance of the stereotyped group. Here, we describe two studies in which we investigated the gender gap on the FCI and CSEM. In the first study, we investigated whether asking students to indicate their gender immediately before taking hte CSEM increased the gender gap compared to students who were not asked for this information. In the second study, conducted with over 1100 introductory physics students, we investigated the prevalence of the belief that men generally perform better in physics than women and the extent to which this belief is correlated with the performance of both the female and male students on the FCI.

description: We present a theoretical study of the dispersion relation of surface plasmon resonances of mesoscopic metal-dielectric-metal microspheres. By analyzing the solutions to Maxwell's equations, we obtain a simple geometric condition for which the system exhibits a band of surface plasmon modes whose resonant frequencies are weakly dependent on the multipole number. Using a modified Mie calculation, we find that a large number of modes belonging to this flat-dispersion band can be excited simultaneously by a plane wave, thus enhancing the absorption cross-section. We demonstrate that the enhanced absorption peak of the sphere is geometrically tunable over the entire visible range.

description: To date, mixed demand systems have been all but ignored in empirical work. A possible reason for the scarcity of such applications is that one needs to know a priori which prices and quantities are endogenous in the mixed demand system. By using a directed acyclical graph (DAG), causal relationships among price and quantity variables are identified giving rise to a causally identified demand system (CIDS). A statistical comparison is made of the traditional Rotterdam model with a Rotterdam mixed demand system identified through the use of a DAG. In this analysis, the respective Rotterdam demand systems consist of five products: steak, ground beef, roast beef, pork, and chicken.

Carbon incorporation was dramatically improved by a two step reaction process at an elevated temperature of 1200 $^o$C. This reaction process results in a solubility limit near x$\sim$0.07. We found that impurities in the starting B cause an additive suppression of T$_c$. We combine these data with T$_c$ and H$_{c2}$(T=0) data from CVD wires as well as plasma spray synthesized powders and present a unifying H$_{c2}$ and T$_c$ versus x plot.

description: In this paper we study the graphane. The Frenkel-Kontorova model on hexagonal lattice was used. We studied the case of one H atom above the C atom in the plane of graphane (we used the approximation of the hexagonal lattice in the plane). Continuous limit of the Lagrange-Euler equations is found from the Hamiltonian for $H$ atoms motion, they enabled us to study kink and breather excitations of $H$ atoms in the $H$ plane above the $C$ plane. We have found that there are three cases in the one $H$ atom motion The case $1$, when the $H$ atom is at the position which is below the position at which it is desorbed. Then the motion of this $H$ atom at time $t_{h}$ is described. The case $2$, when the $H$ atom is at the position of the suppressed atom $H$ in the direction to the $C$ (nearer) atom. This $H$ atom will be desorbed from the graphane going through the minimum of the potential energy and then through the point of desorption. Its motion of at time $t_{h}$ is described. The case $3$, when the $H$ atom is near the position of small oscillations near the potential energy minimum. The position of the atom $H$ at the time $t_{0}$ is the position to which the atom $H$ was excited with external force. The lattice of $H$ atoms in graphane may be excited as described by the kink solution of the Sine-Gordon equation. The kink has its velocity $U$, $ U^{2} < 1$, and in time $T$ and in $X^{'}$ coordinate direction localization. The Sine-Gordon equation has the breather solution in the $X^{'}$ direction. There $ω$ is the frequency of the breather, $T_{0}$ and $X^{'}_{0}$ are in time $T$ and in $X^{'}$ direction localization.

description: In this paper, we estimate the social net benefits of curbside recycling. Benefits are estimated using survey data on household willingness to pay (WTP) from over 4,000 households across 40 western U.S. cities. We calibrate WTP for hypothetical bias using an experimental design that contrasts stated and revealed preferences. Cost estimates are compiled from previous studies by the U.S. Environmental Protection Agency, the Institute for Local Self Reliance, as well as from in-depth interviews with recycling coordinators in our sampled cities. Remarkably, we find that the estimated mean social net benefit of curbside recycling is almost exactly zero. Therefore, the decision of whether to implement or maintain a curbside recycling program (CRP) must be done on a city-by-city basis.

description: Where do quasars reside? Are quasars located in environments similar to those of typical L* galaxies, and, if not, how do they differ? An answer to this question will help shed light on the triggering process of quasar activity. We use the Sloan Digital Sky Survey to study the environment of quasars and compare it directly with the environment of galaxies. We find that quasars (M_i < -22, z < 0.4) are located in higher local overdensity regions than are typical L* galaxies. The enhanced environment around quasars is a local phenomenon; the overdensity relative to that around L* galaxies is strongest within 100 kpc of the quasars. In this region, the overdensity is a factor of 1.4 larger than around L* galaxies. The overdensity declines monotonically with scale to nearly unity at ~1 Mpc, where quasars inhabit environments comparable to those of L* galaxies. The small-scale density enhancement depends on quasar luminosity, but only at the brightest end: the most luminous quasars reside in higher local overdensity regions than do fainter quasars. The mean overdensity around the brightest quasars (M_i < -23.3) is nearly three times larger than around L* galaxies while the density around dimmer quasars (M_i = -22.0 to -23.3) is ~1.4 times that of L* galaxies. By ~0.5 Mpc, the dependence on quasar luminosity is no longer significant. The overdensity on all scales is independent of redshift to z = 0.4. The results suggest a picture in which quasars typically reside in L* galaxies, but have a local excess of neighbors within ~0.1 - 0.5 Mpc; this local density excess likely contributes to the triggering of quasar activity through mergers and other interactions.

description: Because a delay tolerant network (DTN) can often be partitioned, the problem of routing is very challenging. However, routing benefits considerably if one can take advantage of knowledge concerning node mobility. This paper addresses this problem with a generic algorithm based on the use of a high-dimensional Euclidean space, that we call MobySpace, constructed upon nodes' mobility patterns. We provide here an analysis and the large scale evaluation of this routing scheme in the context of ambient networking by replaying real mobility traces. The specific MobySpace evaluated is based on the frequency of visit of nodes for each possible location. We show that the MobySpace can achieve good performance compared to that of the other algorithms we implemented, especially when we perform routing on the nodes that have a high connection time. We determine that the degree of homogeneity of mobility patterns of nodes has a high impact on routing. And finally, we study the ability of nodes to learn their own mobility patterns.

description: We discuss how to embed quantum nonlocality in an approximately classical spacetime background, a question which must be answered irrespective of any underlying microscopic theory of spacetime. We argue that, in deterministic hidden-variables theories, the choice of spacetime kinematics should be dictated by the properties of generic non-equilibrium states, which allow nonlocal signalling. Such signalling provides an operational definition of absolute simultaneity, which may naturally be associated with a preferred foliation of classical spacetime. The argument applies to any deterministic hidden-variables theory, and to both flat and curved spacetime backgrounds. We include some critical discussion of Einstein's 1905 'operational' approach to relativity, and compare it with that of Poincare.

description: By exploiting the computing power and local data of distributed clients, federated learning (FL) features ubiquitous properties such as reduction of communication overhead and preserving data privacy. In each communication round of FL, the clients update local models based on their own data and upload their local updates via wireless channels. However, latency caused by hundreds to thousands of communication rounds remains a bottleneck in FL. To minimize the training latency, this work provides a multi-armed bandit-based framework for online client scheduling (CS) in FL without knowing wireless channel state information and statistical characteristics of clients. Firstly, we propose a CS algorithm based on the upper confidence bound policy (CS-UCB) for ideal scenarios where local datasets of clients are independent and identically distributed (i.i.d.) and balanced. An upper bound of the expected performance regret of the proposed CS-UCB algorithm is provided, which indicates that the regret grows logarithmically over communication rounds. Then, to address non-ideal scenarios with non-i.i.d. and unbalanced properties of local datasets and varying availability of clients, we further propose a CS algorithm based on the UCB policy and virtual queue technique (CS-UCB-Q). An upper bound is also derived, which shows that the expected performance regret of the proposed CS-UCB-Q algorithm can have a sub-linear growth over communication rounds under certain conditions. Besides, the convergence performance of FL training is also analyzed. Finally, simulation results validate the efficiency of the proposed algorithms.

description: Scattered residential development is explained using a theoretical model of residential location in which household interactions generate externalities that determine location choices. Results demonstrate the role of income and heterogeneous preferences in generating this form of sprawl. Among our findings is that rising income generates only temporary increases in sprawl.

Exploring the stepgap : how parents' ways of coping with daily family stressors impact stepparent-stepchild relationship quality in stepfamilies
Creators: name: Preece, Melady
Publisher: name: University of British Columbia
Year: 2009

description: This research focuses on husbands' and wives' perceptions of parent-child relationship quality in stepfamilies. One goal was to examine the links between parents' ways of coping with family stressors and changes in parent-child relationship quality over time. A related goal was to consider the difference in relationship quality for parents' own children and parents' stepchildren. This difference was referred to as the "stepgap". It was expected that characteristics of the family, characteristics of the children, and parents' ways of coping with family stressors would all have an impact on relationship quality. It was also expected that some of these characteristics would alter the "stepgap". Multilevel analyses of family data (Snijders, 1995) were used to replicate consistent findings in the stepfamily literature and extend them by allowing for the drawing of within-family conclusions. For Time 1 relationship quality, characteristics of children and characteristics of the family were modeled on parents' perceptions of relationship quality with individual children. At both levels, the influence of these characteristics on the "stepgap" was also considered. The initial sample interviewed at Time 1 consisted of 154 couples. Of these, 142 couples also participated at Time 2. Husbands initially rated the closeness and tension they perceived in their relationships with 404 children (191 stepchildren, 213 own children). Wives rated the closeness and tension they perceived in their relationships with 407 children (204, stepchildren, 203 own children). Results provided evidence of a "stepgap" in relationship quality for both husbands and wives. However, results also indicated that relationship quality was affected by child age, amount of time spent in the family home, whether there were children from the current union, and the number of years the stepfamily had been in existence. A subsample of these families (81 couples) also provided daily diary data that were used to explore lagged daily relations between parents' reports of affection and tension with children and stepchildren, and parents' ways of coping with family stress. Three ways of coping relevant for interpersonal stressors were examined: compromise, confrontation, and interpersonal withdrawal. Results provided evidence of a direct relationship between parents' ways of coping with family stress and changes in daily relationship quality in terms of affection from children and tension with children. To link the microlevel and the macrolevel, aggregated variables describing parents' typical way of coping with family stressors across a seven-day period were used to explain changes in relationship quality two years later. Results of these analyses indicated that husbands' and wives' coping predicted change not only in the quality of their relationship with children in the stepfamily, but also affected their spouses' stepgap in relationship quality.

Thin films of van der Waals fluid: From interface interactions to wetting transitions

description: We present a theoretical study of wetting phenomena and interactions between liquid-vapor interfaces based on the density functional theory. The focus is mostly on the impact of long-range van der Waals interactions both within the fluid and between the fluid and substrate. For the latter, we consider two models-hard wall and soft wall approximations-differing by the role of steric effects and leading to a qualitatively different character of phase transitions. We compute numerically the disjoining and conjoining potentials (which are important dynamically for spreading, spinodal dewetting, and coarsening in thin films, as well as resolution of interfacial singularities), and loci of intermediate and complete wetting transitions as functions of the Hamaker constant and temperature. We find that taking into account short-range interactions is essential for the description of wetting transitions in the soft wall limit. We derive an analytical form of the disjoining potential and analyze it in the context of the complete, frustrated and partial wetting.

description: To learn about basic aspects of nano-scale spherical molecular shells during their formation, spherically curved two-dimensional N-particle Lennard-Jones systems are simulated, studying curvature evolution paths at zero-temperature. For many N-values (N<800) equilibrium configurations are traced as a function of the curvature radius R. Sharp jumps for tiny changes in R between trajectories with major differences in topological structure correspond to avalanche-like transitions. For a typical case, N=25, equilibrium configurations fall on smooth trajectories in state space which can be traced in the E-R plane. The trajectories show-up with local energy minima, from which growth in N at steady curvature can develop.

description: Deep CCD photometry in the uvby-Hbeta intermediate-band system is presented for the cluster NGC 2548 (M 48). A complete membership analysis based on astrometric and photometric criteria is applied. The photometric analysis of a selected sample of stars yields a reddening value of E(b-y)=0.06\pm0.03, a distance modulus of V_0-M_V=9.3\pm0.5 (725 pc) and a metallicity of [Fe/H]= -0.24\pm0.27. Through isochrone fitting we find an age of log t = 8.6\pm0.1 (400 Myr). Our optical photometry and JHK from 2MASS are combined to derive effective temperatures of cluster member stars. The effective temperature distribution along the main sequence of the cluster shows several gaps. A test to study the significance of these gaps in the main sequence of the HR diagram has been applied. The method is also applied to several other open clusters (Pleiades, Hyades, NGC 1817 and M 67) to construct a sequence of metallicities and ages. The comparison of the results of each cluster gives four gaps with high significance (one of them, centred at 4900 K, has not been previously reported).

description: We examine whether cooperatives are characterized by greater trust than investor-owned firms. We survey 2000 Missouri corn and soybean farmers and find that trust and farmer perceptions of trustworthiness and competence are higher in cooperatives than in investor-owned firms and that trust is a significant factor explaining the choice of farmers to market to cooperatives rather than investor-owned firms. Interestingly, we find that trust is more significant in producers' decisions for marketing soybeans than for corn.
