description: This paper examines the process of implementing land privatization and its effects on household livelihoods in the Uplands of Vietnam. The research was undertaken with three upland villages situated in the buffer zone of Cat Tien National Park in the southern uplands of Vietnam where have recently been adopted a land privatization program according to the 1993 Land Law and some other frontier development programs, such as nature conservation, remotely mountainous community development programs supported by the central government. Such policies and programs have ultimately aimed at improving both upland livelihoods and environmental sustainability of the uplands, simultaneously. The research demonstrates unequivocally that though the land privatization throughout the nationwide has been guided by the unique legal framework, the implementation of land privatization in the uplands, particularly in the buffer zone communities locating around the protected areas has resulted in the notable divergence across communities, even households. The differences in the result of implementing land privatization in the upland communities were mainly caused by different factors embodied in both land legislation and local practices. Unsurprisingly, the divergence of implementing land privatization among communities and households has actually created differentiation in distributing benefits of land privatization among communities and households. In fact, the empirical findings suggest that land privatization (land titling) served only as initial conditions while households´ initial assets play as the determinants factors which determine how households transfer their land title into material benefits. The empirical investigations also suggest that together with land privatization, market liberalization, the government's programs for socio- economic development and nature conservation have strongly influenced on the southern upland livelihoods. Differences in the results of land privatization, households´ initial assets ownership as well benefits from such programs which have been enable households to pursue different patterns and tendencies in livelihood makings. In other words, distributing benefits from land privatization and other government's programs was not equal among households and the ways in which households diversified their livelihoods, differently.

description: Radio emission models of colliding wind binaries (CWBs) have been discussed by Dougherty et al. (2003). We extend these models by considering the temporal and spatial evolution of the energy distribution of relativistic electrons as they advect downstream from their shock acceleration site. The energy spectrum evolves significantly due to the strength of inverse-Compton (IC) cooling in these systems, and a full numerical evaluation of the synchrotron emission and absorption coefficients is made. We have demonstrated that the geometry of the WCR and the streamlines of the flow within it lead to a spatially dependent break frequency in the synchrotron emission. We therefore do not observe a single, sharp break in the synchrotron spectrum integrated over the WCR, but rather a steepening of the synchrotron spectrum towards higher frequencies. We also observe that emission from the wind-collision region (WCR) may appear brightest near the shocks, since the impact of IC cooling on the non-thermal electron distribution is greatest near the contact discontinuity (CD). We show that the thermal emission from a CWB can mimic a thermal plus non-thermal composite spectrum if the thermal emission from the WCR becomes comparable to that from the unshocked winds, and obtain a number of insights relevant to models of closer systems such as WR140. Finally, we apply our new models to the very wide system WR147. The acceleration of non-thermal electrons appears to be very efficient in our models of WR147, and we suggest that the shock structure may be modified by feedback from the accelerated particles.

Teaching civilization : gender, sexuality, race and class in two late nineteenth-century British Columbia missions
Creators: name: Greenwell, Kim
Publisher: name: University of British Columbia
Year: 2009

description: Despite the recent proliferation of work around the subject of residential schools, few analyses have deconstructed the concept of "civilizing the Indian" which animated the schools' agendas. This thesis examines the discourse of "civilization" as it was expressed and enacted in two missions in late nineteenth-century British Columbia. Archival primary sources and published secondary sources are drawn on to provide an understanding of what "civilization" meant to Euro-Canadians, specifically missionaries, and how it was to be "taught" to the indigenous peoples they encountered. Colonial images and photographs, in particular, reveal how missionaries constructed a vivid and compelling contrast between "civilization" and "savagery." An intersectional framework is employed to highlight the ways in which ideas about "race," class, gender and sexuality were essential elements of the "civilizing" project. The goal of the thesis is to show how "civilizing the Indian" was premised not only on a specifically hierarchical construction of Whites versus Natives, but also intersecting binaries of men versus women, normal productive heterosexuality versus deviant degenerate sexuality, bourgeois domesticity versus lower class depravity, and others. Ultimately, it is argued, the discourse of "civilization" regulated both the "colonized" and the "colonizers" as it secured the hierarchical foundations of empire and nation.

description: The Farmer Field School (FFS) is an intensive training program providing farmers with science based knowledge and practices, including the integrated pesticide management (IPM). Recently there has been intensive debates as to whether or not this kind of training has any significant impact. Most case studies argue that the impact, in terms of a farmers ability to reduce the use or pesticides while increasing yields, is significant. However, studies conducted by Feder et al., using a household panel data set for Indonesia, could not confirm that this is the case. This paper utilises Feder et al.s data set and applies a spatial econometric technique to re-evaluate whether or not the FFS induces better performances among farmers enrolled in the program and also among their neighbours, who are expected to receive some spillover knowledge from the FFS alumna.

description: The three-state Ising neural network with synchronous updating and variable dilution is discussed starting from the appropriate Hamiltonians. The thermodynamic and retrieval properties are examined using replica mean-field theory. Capacity-temperature phase diagrams are derived for several values of the pattern activity and different gradations of dilution, and the information content is calculated. The results are compared with those for sequential updating. The effect of self-coupling is established. Also the dynamics is studied using the generating function technique for both synchronous and sequential updating. Typical flow diagrams for the overlap order parameter are presented. The differences with the signal-to-noise approach are outlined.

description: This paper analyses the economic effects of different magnitudes of tariff cuts, different tariff cutting formulas, the implications of tariff capping as well as different numbers and width of tariff bands in the market access pillar of the Doha Round agricultural negotiations. The simulations are conducted with an extended version of the GTAP model and an extended version of the GTAP data base (6.0) including bound and applied rates. The results reveal that the EU-27 experiences a negative change of its trade balance in the highly protected beef and sugar sectors. The relative increase of EU beef and sugar imports is mainly evoked by the magnitude of tariff cuts and, to a lesser extent, by the kind of formula used to implement the tariff cuts. In contrast, the EU trade balance for milk and cereals is hardly influenced by different options to cut tariffs. Here, the negative change of the trade balance is mainly driven by the elimination of export subsidies. The results also indicate a relative increase of EU exports for other meat, if tariff cuts are high enough to open third countries' markets to the EU.

(N.Y.) {\bf 311}, 503 (2004)] is applied to quantum scattering of Schrödinger particles from non-local separable potentials. Eigenchannel vectors and negative cotangents of eigenphase-shifts are introduced as eigensolutions to some weighted matrix spectral problem, without a necessity of prior construction and diagonalization of the scattering matrix. Explicit expressions for the scattering amplitude, the total cross section in terms of the eigenchannel vectors and the eigenphase-shifts are derived. An illustrative example is provided.

description: Entanglement and steering are used to describe quantum inseparabilities. Steerable states form a strict subset of entangled states. A natural question arises concerning how much territory steerability occupies entanglement for a general two-qubit entangled state. In this work, we investigate the constraint relation between steerability and concurrence by using two kinds of evolutionary states and randomly generated two-qubit states. By combining the theoretical and numerical proofs, we obtain the upper and lower boundaries of steerability. And the lower boundary can be used as a sufficient criterion for steering detection. Futhermore, we consider a special kind of mixed state transformed by performing an arbitrary unitary operation on Werner-like state, and propose a sufficient steering criterion described by concurrence and purity.

Agricultural Growth and Economic Development: A View through the Globalization Lens

Year: 2006
Subjects: International Development

description: This paper re-visits the age old proposition that agriculture growth contributes to overall economic development, and asks whether the relationship still holds in an increasingly globalized world. There is overwhelming empirical support for the above proposition, indeed, it is hard to find exceptions, barring a few city states, where sustained economic development has not been preceded by robust agricultural growth. However, there are a large number of countries that have witnessed neither agricultural growth nor economic development. Even in countries where agricultural growth has been significant, dramatic inter-regional differences persist. This paper examines the factors that contribute to or constrain the process of agricultural transformation. Does the process of globalization, and the resultant changes in agrifood systems, offer new opportunities for agriculture led growth, or will it further marginalize excluded countries, regions and groups? The factors that cause exclusion are examined both in terms of globalization forces and in terms of domestic shortcomings in policies and governance. Policy interventions that attempt to reduce the costs of transition to a globalized agricultural system are explored, including safety nets for those left behind.

description: In this paper, we consider rotating multistate boson stars with quartic self-interactions. In contrast to the nodeless quartic-boson stars in \cite{Herdeiro:2015tia}, the self-interacting multistate boson stars (SIMBSs) have two types of nodes, including the $^1S^2S$ and $^1S^2P$ states. We show the mass $M$ of SIMBSs as a function of the synchronized frequency $ω$, and the nonsynchronized frequency $ω_2$ for three different cases. Moreover, for the case of two coexisting states with self-interacting potential, we study the mass $M$ of SIMBSs versus the angular momentum $J$ for the synchronized frequency $ω$ and the nonsynchronized frequency $ω_2$. Furthermore, for three different cases, we analyze the coexisting phase with both the ground and first excited states for SIMBSs. We also calculate the maximum value of coupling parameter $Λ$, and find the coupling parameter $Λ$ exists the finite range.

description: The censored Tobit model is applied on data from the Malaysian Household Expenditure Survey (1998/99) to identify socio-demographic determinants of household expenditures on food-away-from-home (FAFH). Results indicate that Chinese, urban residents, and those with higher monthly household income spend significantly more on FAFH expenditures than their non-Chinese, rural, and lower household income cohorts, ceteris paribus. Other results obtained suggest that age of household head, gender, education level and household size do not significantly affect household expenditures on FAFH. Based on the above findings, several observations are noted. First, the current range of menus being served can be further diversified in order to attract those with religious and other diet restrictions. Opportunities exist to expand the range of FAFH to tap into the 'Halal' food market. Second, to further penetrate the FAFH market, efforts should be made to reach out to those staying in the rural areas that may not have access to advertising and marketing campaigns. Publicity campaigns in the form of regional radio and newspaper advertisements would be most effective in penetrating these areas. Third, mid-level FAFH establishments should consider appropriate pricing strategies to attract consumers from all income levels. Lastly, the Malaysian FAFH market appears to be continuing on its upward trend although there exists no significant differences between the old-young, male-female, higher-lower educated, or large-small family size in determining the amount of money spent on eating out.

description: Mixed evidence on the impact of formal title in much of Africa is often used to question the relevance of dealing with land policy issues in this continent. We use data from Uganda to assess the impact of a disaggregated set of rights on investment, productivity, and land values and to test the hypothesis that individuals' lack of knowledge of the new law reduces their tenure security. Results point towards strong and positive effects of greater tenure security and transferability. Use of exogenous knowledge of its provisions as a proxy for the value of the land law suggests that this piece of legislation had major economic benefits that remain to be fully realized.

description: This paper develops the structure and closure of an econometric regime-switching model within a partial equilibrium framework that has the ability to generate reliable estimates and projections of endogenous variables under market switching regimes. Models used in policy evaluation usually either ignore the possibility of regime switching using just a single method of price determination based on average effects, or incorporate highly stylised components that may not reflect the complexities of a particular market. This paper proposes an approach that the authors believe allows the incorporation of features of regime switching in a multisector commodity level model that capture salient features of the South African market and therefore are able to produce more reliable projections of the evolution of the sector under alternative shocks.
An application of multivariate analysis to time of day routing in telecommunication networks
Creators: name: Smith, Isabelle
Publisher: name: University of British Columbia
Year: 2009

description: The work presented in this thesis is a component of a larger project that is currently under way at the Center for Operations Excellence. This project was initiated in May of 1999. The main goal of this project is to help Telus reduce their yearly investments in the nontoll network by optimizing the current use of their telephone network. We chose to accomplish this by determining a new set of routing rules that would make the most efficient use of their current network. Three main approaches were selected to obtain this new set of routing rules. The first one was the development of a simulation that could serve as a test-bed to compare different sets of routing rules and to determine the optimal set. The second approach was the use of a linear program that would generate routing rules that minimize network utilization. Finally, we have approached the challenge of optimizing the network utilization by using multivariate analysis to help develop routing rules for time of day routing. This last approach is described in this thesis. The objective of this thesis was to develop a methodology, using multivariate analysis, that would help us find if there were possible alternate routes that could be added to the current ones, which would take advantage of excess capacity in certain regions in the network. This methodology was developed in SAS and included the use of Principal Components Analysis, Clustering Analysis and the development of an algorithm that would search for adjacent arcs that had sufficient available capacity to serve as alternate routes during certain periods of the day. It was found that there are alternate routes that can be used during certain times of the day and that these routes can be found by using the methodology described in this thesis. This result is of great value to telephone companies as this means that there is a way for them to use existing capacity more efficiently and therefore avoid or delay investments into adding capacity to the telephone network.
Scale Radii and Aggregation Histories of Dark Haloes

description: Relaxed dark-matter haloes are found to exhibit the same universal density profiles regardless of whether they form in hierarchical cosmologies or via spherical collapse. Likewise, the shape parameters of haloes formed hierarchically do not seem to depend on the epoch in which the last major merger took place. Both findings suggest that the density profile of haloes does not depend on their aggregation history. Yet, this possibility is apparently at odds with some correlations involving the scale radius r_s found in numerical simulations. Here we prove that the scale radius of relaxed, non-rotating, spherically symmetric haloes endowed with the universal density profile is determined exclusively by the current values of four independent, though correlated, quantities: mass, energy and their respective instantaneous accretion rates. Under this premise and taking into account the inside-out growth of haloes during the accretion phase between major mergers, we build a simple physical model for the evolution of r_s along the main branch of halo merger trees that reproduces all the empirical trends shown by this parameter in N-body simulations. This confirms the conclusion that the empirical correlations involving r_s do not actually imply the dependence of this parameter on the halo aggregation history. The present results give strong support to the explanation put forward in a recent paper by Manrique et al. (2003) for the origin of the halo universal density profile.

description: Maize is a key food crop in Kenya. While maize yields increased from 1.25 t ha-1 in early 1960s to over 2 tonnes in 1982, they fell below 1.5 t ha-1 in 2000. Given the limited land area, there is no doubt that Kenya will have to rely more on modern technologies for increased yields .Use of improved maize varieties and fertilizers will therefore continue to be critical inputs for improving productivity. To improve production, it is important to understand factors determining adoption and intensity of use of modern technologies. A stratified 2-stage sampling design was used to select 1800 households, subsequently interviewed by means of structured questionnaire. Econometric models were used to explore factors influencing adoption and intensity of use of the improved varieties and fertilizer. Access to credit was positively related to adoption and intensity of use of the two inputs. Extension contacts positively influenced the likelihood of adoption of improved maize seed, while amount of planting fertilizer used positively influenced both the adoption and intensity of use of improved varieties. Distance to market negatively determined the adoption and intensity of use of fertilizer. In addition gender and access to hired labour had negative impacts on the intensity of use of fertilizer. There is need to think of alternative sources of credit to farmers and also revamp the existing extension service (including privatization in the long term) for efficient delivery of information.

description: The standard literature on working time has modelled the decisions of firms in a deterministic framework in which firms can choose between employment and overtime (given mandated standard hours). Contrary to this approach, we follow the real options approach, which allows us to investigate the value to a firm of waiting to adjust labour when the firm´s revenues in domestic currency are stochastic and adjustment costs are sunk. The simulations reject the null hypothesis that all exchange rate regimes obey common employment adjustment thresholds.

Most of the objects have recently been found by Karachentseva & Karachentsev based on POSSII/ESO-SERC survey. A hundred more dSph galaxies are expected in this volume, being missed so far because of their low luminosity and low surface brightness. Apart from 22 dSph members of the Local Group, there are 33 dSphs in other nearby groups that have been resolved recently into stars with HST. Only 5% of the local dSphs are situated outside the known groups. We discuss observational correlation between basic parameters of the dwarf spheroidal galaxies, in particular, absolute magnitude, surface brightness, metallicity, and so-called "tidal index". The observed number of dSphs in group increases with luminosity of its brightest galaxy. In a "synthetic" nearby group, dwarf spheroidal galaxies are distributed in depth quite symmetrically about the principal galaxy, having an rms distance scatter of 200 kpc. Projected radial distribution of dSphs in the synthetic group follows the profile N(R) ~ exp(-R/200 kpc).

description: Similarity search in high-dimensional spaces is an important task for many multimedia applications. Due to the notorious curse of dimensionality, approximate nearest neighbor techniques are preferred over exact searching techniques since they can return good enough results at a much better speed. Locality Sensitive Hashing (LSH) is a very popular random hashing technique for finding approximate nearest neighbors. Existing state-of-the-art Locality Sensitive Hashing techniques that focus on improving performance of the overall process, mainly focus on minimizing the total number of IOs while sacrificing the overall processing time. The main time-consuming process in LSH techniques is the process of finding neighboring points in projected spaces. We present a novel index structure called radius-optimized Locality Sensitive Hashing (roLSH). With the help of sampling techniques and Neural Networks, we present two techniques to find neighboring points in projected spaces efficiently, without sacrificing the accuracy of the results. Our extensive experimental analysis on real datasets shows the performance benefit of roLSH over existing state-of-the-art LSH techniques.

description: We do meson spectroscopy by studying the behavior of S-matrix poles in the complex-energy plane, as a function of the coupling strength for triplet-P-zero quark-pair creation. Thereto, a general formula for non-exotic hadron-hadron scattering involving arbitrary quark confinement is used, which can be applied to all flavors. We find two distinct types of poles, which we call "confinement" and "continuum" poles, respectively. Together, they suffice to understand the experimental meson spectrum.

description: Bundles of many fibers, with statistically distributed thresholds for breakdown of individual fibers and where the load carried by a bursting fiber is equally distributed among the surviving members, are considered. During the breakdown process, avalanches consisting of simultaneous rupture of several fibers occur, with a distribution D(Delta) of the magnitude Delta of such avalanches. We show that there is, for certain threshold distributions, a crossover behavior of D(Delta) between two power laws D(Delta) proportional to Delta^(-xi), with xi=3/2 or xi=5/2. The latter is known to be the generic behavior, and we give the condition for which the D(Delta) proportional to Delta^(-3/2) behavior is seen. This crossover is a signal of imminent catastrophic failure in the fiber bundle. We find the same crossover behavior in the fuse model.

description: Liberalization and regulatory reform of telecom markets has emerged as a high profile policy issue. This paper analyzes how the multilateral system under the World Trade Organization can help developing countries in promoting their own information infrastructures. We focus on a specific "regime" issue that has attracted increasing attention in recent years: the extent to which the WTO should pursue a "deeper integration" agenda, using telecommunications and activities that rely heavily on telecommunications as a specific case. Die Liberalisierung und Reform der Telekommunikationsmärkte ist zu einem wichtigen politischen Thema geworden. Dieser Beitrag analysiert, wie das multilaterale System - unter der Welthandelsorganisation - Entwicklungsländern bei der Förderung ihrer eigenen Informations-Infrastruktur helfen kann. Wir konzentrieren uns auf eine spezifische "Regime"-Frage, die in den letzten Jahren zunehmend Aufmerksamkeit erregt hat: In welchem Maße die WTO ein Programm der "tieferen Integration" verfolgen sollte, das Telekommunikation als spezifischen Fall betrachtet.

description: Finding nearest neighbors in high-dimensional spaces is a fundamental operation in many multimedia retrieval applications. Exact tree-based indexing approaches are known to suffer from the notorious curse of dimensionality for high-dimensional data. Approximate searching techniques sacrifice some accuracy while returning good enough results for faster performance. Locality Sensitive Hashing (LSH) is a very popular technique for finding approximate nearest neighbors in high-dimensional spaces. Apart from providing theoretical guarantees on the query results, one of the main benefits of LSH techniques is their good scalability to large datasets because they are external memory based. The most dominant costs for existing LSH techniques are the algorithm time and the index I/Os required to find candidate points. Existing works do not compare both of these dominant costs in their evaluation. In this experimental survey paper, we show the impact of both these costs on the overall performance of the LSH technique. We compare three state-of-the-art techniques on four real-world datasets, and show that, in contrast to recent works, C2LSH is still the state-of-the-art algorithm in terms of performance while achieving similar accuracy as its recent competitors.

Freyastera delicata: Zhang et al. 2019: 2; Zhang et al. 2024: 10.
Material examined.
RSIOAST 0022 (holotype). RSIOAST 0135 (Figs 5, 14 D). (Suppl. material 1).
Diagnosis.
Arms six. Abactinal disk and arm plate each bears multiple spines (usually 4–8), most measuring 0.5–0.8 mm in length, not covered by membranous sheath. Pedicellariae absent on abactinal surface of disk and arm genital area. Pedicellariae cluster in transverse bands on abactinal arm beyond genital area. One long aboral spine and one subambulacral spine on each adambulacral plate. Proximal subambulacral spines with truncate end. Lateral spine corresponds to every adambulacral plate beyond genital area. Oral plate bears two actinostomal spines, one suboral spine, and one aboral furrow spine.
Distribution.
Northwest Pacific: Caiwei Seamount, O-Hakucho Guyot, 3121–4322 m. Type locality: Caiwei Seamount, 4322 m.
Remarks.
The species was described based on a single specimen (holotype RSIOAST 0022) (Zhang et al. 2019). An additional specimen was examined in the present study, providing information on intraspecific variations of the species. The specimen RSIOAST 0135 (Fig. 5) is smaller compared to the holotype, with maximum R = 135 mm, r = 4.1 mm, R / r ≈ 33. The arm measures 3.5 mm wide at the base, whereas the widest part of arm measures 4.6 mm. The genital area is about 9.5 mm in length. Gonads well-developed, female (Fig. 5 G). Abactinal arm spines slightly longer than those in the holotype, but not aligned in transverse rows as in the holotype (Fig. 5 D). The new specimen shares other characters with the holotype, including having no trace of pedicellariae on abactinal disk and genital area (Fig. 5 B, D), mouth plate with two actinostomal spines, one suboral spine, and one aboral furrow spine (Fig. 5 A), adambulacral plate with one subambulacral spine and one aboral spine pointing upwardly (Fig. 5 C, E), abactinal arm plate with several spines, and arm beyond genital area with transverse bands of pedicellariae (Fig. 5 H). The new specimen was found at 3121 m depth from O-Hakucho Guyot, close to the type locality (Fig. 1), but is 1201 m shallower than the depth of the holotype (4322 m).

Internationale Migration Gehen oder Bleiben: Wieso gehen wenige und bleiben die meisten?

description: Was bestimmt das individuelle Wanderungsverhalten? Herkömmliche migrationsökonomische Theorieansätze greifen oft zu kurz und überschätzen deshalb die grenzüberschreitenden Wanderungsbewegungen bei weitem. Dieses Diskussionspapier stellt die bisherige Optik auf den Kopf und sucht nach Faktoren, die erklären können, weshalb die meisten Menschen international immobil bleiben. Bleiben ist in den meisten Fällen eine mikroökonomisch rationale Entscheidung, selbst wenn makroökonomisch gewaltige Differenzen in den durchschnittlichen Verdienst- oder Beschäftigungsmöglichkeiten bestehen. Der von Fischer/Holm/Malmberg/Straubhaar (2000) vorgeschlagene Insider-Ansatz zur Erklärung von Immobilität vermag zu erklären, weshalb als individuelle Entscheidung eine grenz- und kulturraumüberschreitende Wanderung die Ausnahme und nicht die Regel ist. Dieses Ergebnis ist deshalb von großer wirtschaftspolitischer Relevanz, weil es letztlich die Erwartungen in starke Ost-West-Wanderungen nach einer EU-Osterweiterung relativiert und eher geringe als starke Wanderungsströme von Ost- nach Westeuropa erwarten lässt. What factors determine the individual decision to migrate? This paper argues that standard migration theories often concentrate too strongly on explanations as to why people (should) go and therefore in many cases overestimate the incentives to move. However, most people stay. Thus, this paper looks at how we can explain the fact that most people are immobile and do not move internationally. It starts with some traditional arguments and ends with the insider advantages approach developed by Fischer/Holm/Malmberg/Straubhaar (2000). The results (i.e. that staying is the preferred alternative) are of considerable political interest for the debate on EU eastward enlargement as they indicate that the freedom of movement of labour within an eastwards enlarged common labour market will not generate very much east-west migration.
