description: This study analyzes the determinants of land tenure insecurity and its impact on intensity of use of purchased farm inputs among households in Southern Ethiopia. Seventeen percent of the households stated that they were tenure insecure. The feeling of tenure insecurity could be caused by the land redistribution policy in Ethiopia where household size has been the main criterion used for land allocation after the land reform in 1975. This would imply that land rich households should be more tenure insecure. Alternatively, the local power structure may be strong enough to counter this and cause the land rich, who are also likely to be influential, to be able to protect their land rights. The analysis revealed that, in the overall sample, relative farm size was not significantly correlated with tenure insecurity. When testing for each site, however, we found that in four of the sites per capita farm size was positively associated with tenure insecurity, while in five other sites it had a significant negative association. This may be due to local historical, cultural, and demographic differences giving way to differences in the effects of the redistribution policy and the local power structure on tenure insecurity. We assessed the impact of tenure insecurity on the intensity of use of purchased farm inputs. The tenure insecurity variable was insignificant. Farmers in areas with a positive correlation between farm size and tenure insecurity were more likely to purchase farm inputs. Larger farms were more likely to use purchased inputs, but this effect was lower in areas with a positive correlation between farm size and tenure insecurity. Poverty and subsistence constraints may explain this absence of higher intensity of use of purchased inputs on small farms. By contrast, the land redistribution policy may have improved small farms’ access to purchased farm inputs.

description: Water and watersheds are difficult to separate for management purposes. Providing irrigation as a supplement to rainfall for crop production requires considerable collective action at the watershed level to mobilize labor and other resources, as well as to make decisions and implement the distribution of benefits. Small- scale water harvesting irrigation systems in Mexico have endured for centuries. They now face considerable challenges with changes in the ejido property rights over land and water, the growing importance of alternative sources of livelihoods, and increasing scarcity and competition for water within the river basins. Two case studies of water harvesting irrigation systems in the Lerma-Chapala Basin illustrate the response of communities to these challenges. In the first community, earlier collective action to build the irrigation reservoir provided a platform to address catchment resource use. Water here was less scarce than in the second community, allowing for good crop productivity through sufficient irrigation. Water scarcity in the second community increases crop risk; expected sorghum yields during the period of field study did not justify harvesting costs and the crop was used as stover. Members of the second community increased their dependence on off- farm income sources, but still responded collectively to external forces claiming the water.

description: Deep domain adaptation methods have achieved appealing performance by learning transferable representations from a well-labeled source domain to a different but related unlabeled target domain. Most existing works assume source and target data share the identical label space, which is often difficult to be satisfied in many real-world applications. With the emergence of big data, there is a more practical scenario called partial domain adaptation, where we are always accessible to a more large-scale source domain while working on a relative small-scale target domain. In this case, the conventional domain adaptation assumption should be relaxed, and the target label space tends to be a subset of the source label space. Intuitively, reinforcing the positive effects of the most relevant source subclasses and reducing the negative impacts of irrelevant source subclasses are of vital importance to address partial domain adaptation challenge. This paper proposes an efficiently-implemented Deep Residual Correction Network (DRCN) by plugging one residual block into the source network along with the task-specific feature layer, which effectively enhances the adaptation from source to target and explicitly weakens the influence from the irrelevant source classes. Specifically, the plugged residual block, which consists of several fully-connected layers, could deepen basic network and boost its feature representation capability correspondingly. Moreover, we design a weighted class-wise domain alignment loss to couple two domains by matching the feature distributions of shared classes between source and target. Comprehensive experiments on partial, traditional and fine-grained cross-domain visual recognition demonstrate that DRCN is superior to the competitive deep domain adaptation approaches.

Extended Source Effects in Substructure Lensing

subject: FOS: Physical sciences

description: We investigate the extended source size effects on gravitational lensing in which a lens consists of a smooth potential and small mass clumps (``substructure lensing''). We first consider a lens model that consists of a clump modeled as a singular isothermal sphere (SIS) and a primary lens modeled as an external background shear and convergence. For this simple model, we derive analytic formulae for (de)magnification of circularly symmetric top-hat sources with three types of parity for their lensed images, namely, positive, negative, and doubly negative parities. Provided that the source size is sufficiently larger than the Einstein radius of the SIS, we find that in the positive (doubly negative) parity case, an extended source is always magnified (demagnified) in comparison with the unperturbed macrolens system, whereas in the negative parity case, the (de)magnification effect, which depends on the sign of convergence minus unity is weaker than those in other parities. It is shown that a measurement of the distortion pattern in a multiply lensed image enables us to break the degeneracy between the lensing effects of clump mass and those of clump distance if lensing parameters of the relevant macrolens model are determined from the position and flux of multiple images. We also show that an actual density profile of a clump can be directly measured by analyzing the ``fine structure'' in a multiply lensed image within the Einstein radius of the clump.

description: In this paper, we develop an empirical model of an agro-pastoral system subject to high climatic risk to test the impact of rainfall variability on livestock densities, land allocation patterns and herd mobility observed at the community level. Also, because grazing land is a common-pool resource, we determine the impact of cooperation on these decision variables. To capture different abilities of communities to manage these externalities, we construct indices comprised of factors considered to affect the costliness of achieving successful cooperation found in the collective action literature. We then test hypotheses regarding the impact of rainfall variability and cooperation using data collected in a semi-arid region of Niger. Results indicate that rainfall variability first leads to higher and then lower stock densities, indicating that benefits of accumulating large herds in variable environments are eventually offset by the higher risks of low production and higher mortality. Communities with characteristics hypothesized to favor cooperation have lower stock densities and greater herd mobility. Neither cooperation nor rainfall variability has a significant impact on the proportion of land allocated to crops vs. common pastures.
Quiescent times in Gamma-Ray-Bursts: hints of a dormant inner engine

description: We perform a statistical analysis of the temporal structure of long Gamma-Ray-Bursts (GRBs). First we consider a sample of bursts in which a long quiescent time is present. Comparing the pre-quiescence with the post-quiescence emission we show that they display similar temporal structures, hardness ratios and emitted powers, but, on the average, the post-quiescence emission is roughly twice as long as the pre-quiescence emission. We then consider a sample of long and bright GRBs. We show that the duration of each emission period is compatible with the duration of an active period computed in various inner engine models. At the contrary, if the inner engine is assumed to be always active, i.e. also during the quiescent times, in several cases the total duration of the burst largely exceeds the theoretical durations. Our analysis therefore does not support the interpretation of long quiescent times in terms of stochastic modulation of a continuous wind. Instead the quiescent times can be interpreted as dormancy periods of the inner engine. Before and after a dormancy period the inner engine produces similar emissions.

description: We numerically model key building blocks of a phononic integrated circuit that enable phonon routing in high-acoustic-index waveguides. Our particular focus is on Gallium Nitride-on-sapphire phononic platform which has recently demonstrated high acoustic confinement in its top layer without the use of suspended structures. We start with systematic simulation of various transverse phonon modes supported in strip waveguides and ring resonators with sub-wavelength cross-section. Mode confinement and quality factors of phonon modes are numerically investigated with respect to geometric parameters. Quality factor up to $10^{8}$ is predicted in optimized ring resonators. We next study the design of the phononic directional couplers, and present key design parameters for achieving strong evanescent couplings between modes propagating in parallel waveguides. Last, interdigitated transducer electrodes are included in the simulation for direct excitation of a ring resonator and critical coupling between microwave input and phononic dissipation. Our work provides comprehensive numerical characterization of phonon modes and functional phononic components in high-acoustic-index phononic circuits, which supplements previous theories and contributes to the emerging field of phononic integrated circuits.

title: Understanding plant-soil interactions of native and non-native plants under climatic extremes
Creators: name: Sanders, Shareen
Publisher: name: Universität Bern
Year: 2025
Subjects: subject: 570 Life sciences; biology

description: Many theoretical concepts developed to explain the success of non-native plant species have often
centered on the phenotypic traits of the non-native plant or the features of the native environment.
While these theories have faced conflicting evidence, there is a considerable amount of evidence
suggesting that drought creates windows of opportunity for certain non-native plants to thrive. While
current frameworks are primarily based on seasonal droughts, the unique characteristics of extreme
droughts necessitate reevaluating our understanding of drought-mediated plant invasion. Likewise,
biotic interactions with other trophic groups play a major role in determining the success of a non-native
plant in a novel community. Here, we aim to explore aspects through which extreme drought facilitates
the invasion of non-native species, focusing on the trait responses of the non-native plant, the presence
of soil microbes such as mycorrhizal fungi and the plant-soil feedback (PSF) effect of the native plant
community differing in traits, diversity and the presence of an invasive plant. In the following chapters,
we investigate:
1) how extreme drought, extreme flooding and sequential extreme drought and flooding events impact
the PSF effect of invasional meltdown (Chapter 1),
2) how intraspecific competition impacts the extreme drought recovery of a range-expanding and native
congener in the presence of mycorrhizal fungi (Chapter 2; Sanders et al. 2024), and,
3) how extreme drought and in the presence of mycorrhizal fungi impact the PSF effect on plant
communities differing in plant traits and diversity (Chapter 3).
4) Lastly, we speculate how extreme drought mediated invasibility also depends on the ecological
response of the native communities as well as the ecological barriers at different invasive stages
(Chapter 4; Sanders et al. 2024).

description: This paper characterizes and measures the contribution of social capital to the performance of 50 agroenterprises in Colombia. Using qualitative analysis we document how social capital performs a variety of functions in firms, including providing access information via networks of contacts, reducing transactions costs in contracting via trust, and sustaining capacity for collective action. To estimate social capital's contribution to firm structure and performance, quantitative indicators of firm-level use of social capital are developed based on the number and strength of relationships that firms maintain. Econometric analysis finds that firm-level returns to relationships are high, higher than to physical or human capital. The results suggests that while firms can increase their economic performance by investing in social capital, institutional and technological innovations that ameliorate the effects of the market failures that lead to use of social relationships for business purposes could also improve both equity and efficiency.

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: The Ising model in uncorrelated scale-free networks has been studied by means of Monte Carlo simulations. These networks are characterized by a degree (or connectivity) distribution $P(k) \sim k^{-γ}$. The ferromagnetic-paramagnetic transition temperature has been studied as a function of the parameter $γ$. For $γ> 3$ our results agree with earlier analytical calculations, which found a phase transition at a temperature $T_c(γ)$ in the thermodynamic limit. For $γ\leq 3$, a ferromagnetic-paramagnetic crossover occurs at a size-dependent temperature $T_{co}$, and the system is in the ordered ferromagnetic state at any temperature for a system size $N \to \infty$. For $γ= 3$ and large enough $N$, the crossover temperature is found to be $T_{co} \approx A \ln N$, with a prefactor $A$ proportional to the mean degree. For $2 < γ< 3$, we obtain $T_{co} \sim < k > N^z$, with an exponent $z$ that decreases as $γ$ increases. This exponent is found to be lower than predicted by earlier calculations.

Capitalizing on democracy : the maintenance of the Korean developmental state and the promotion of small & medium enterprises
Creators: name: Weisbart, Michael James
Publisher: name: University of British Columbia
Year: 2009

description: This study explores the relationship between democracy and the developmental state in Korea. It deals directly with two important puzzles: 1) If the developmental state has truly been dismantled, how can we explain the fact that it is continuing to identify strategic industries of the. future and then finance and underwrite their development through industrial policy? 2) How can we reconcile evidence of strong, concerted state behavior with normal assumptions that democracy and the developmental state are incompatible? Typical studies have provided accounts of the litany of reform measures that have appeared as early as 1980, concluding that the developmental state is no more. This study goes beyond those, arguing that the reforms only tell us one side of the story. It takes for granted that the old Korean developmental state model is gone. Rather, this study begins from the premise that if the institution is to be pronounced dead, scholars must first determine finally that the state is no longer acting as a developmental state, that it has not adapted and transformed itself in such a way(s) as to continue to promote economic development beyond an Anglo-American model. Unfortunately for celebrants at the developmental state's funeral, the empirical evidence does not support a simple thesis of demise. This paper has two major findings: One, the Korean Developmental State is extant, that convergence with an Anglo-American model has not obtained and is unlikely to in the future. Two, assumptions of the incompatibility of democracy and the developmental state are unfounded, at least in the Korean milieu. These two conclusions are arrived at through a diachronic exploration of the South Korean political economy before and after 1987 and, specifically, by exploring the strengthening of state promotion policy for Small and Medium Enterprises after the 1987 democratic transition.

Noticeable portion of molecules in the ensemble show a behavior which is inconsistent with the standard tunneling model: Their spectral lines are subject to irreversible spectral jumps, continuous shifting, and abrupt chaotic changes of the linewidth or jumping rate. In films thinner than 100 nm, the occurrence of "non-standard" spectral behavior increases with decreasing sample thickness at fixed excitation intensity. In addition, it also increases with laser intensity.

description: The effect of the variation of oxygen content on structural, magnetic and transport properties in the electron-doped manganites La0.9Te0.1MnOy has been investigated. All samples show a rhombohedral structure with the space group . The Curie temperature decreases and the paramagnetic-ferromagnetic (PM-FM) transition becomes broader with the reduction of oxygen content. The resistivity of the annealed samples increases slightly with a small reduction of oxygen content. Further reduction in the oxygen content, the resistivity maximum increases by six orders of magnitude compared with that of the as-prepared sample, and the r(T) curves of samples with y = 2.86 and y = 2.83 display the semiconducting behavior () in both high-temperature PM phase and low-temperature FM phase, which is considered to be related to the appearance of superexchange ferromagnetism (SFM) and the localization of carriers. The results are discussed in terms of the combined effects of the increase in the Mn2+/(Mn2++Mn3+) ratio, the partial destruction of double exchange (DE) interaction, and the localization of carriers due to the introduction of oxygen vacancies in the Mn-O-Mn network.

description: A large fraction of accreting black hole and neutron stars systems present clear evidence of the reprocessing of X-rays in the atmosphere of an optically-thick accretion disk. The main hallmarks of X-ray reflection include fluorescent K-shell emission lines from iron ($\sim 6.4-6.9$ keV), the absorption iron K-edge ($\sim 7-9$ keV), and a broad featureless component known as the Compton hump ($\sim 20-40$ keV). This Compton hump is produced as the result of the scattering of high-energy photons ($E \gtrsim 10$ keV) of the relatively colder electrons ($T_e \sim 10^5-10^7$ K) in the accretion disk, in combination with photoelectric absorption from iron. The treatment of this process in most current models of ionized X-ray reflection has been done using an approximated Gaussian redistribution kernel. This approach works sufficiently well up to $\sim100$ keV, but it becomes largely inaccurate at higher energies and at relativistic temperatures ($T_e\sim10^9$ K). We present new calculations of X-ray reflection using a modified version of our code XILLVER, including an accurate solution for Compton scattering of the reflected unpolarized photons in the disk atmosphere. This solution takes into account quantum electrodynamic and relativistic effects allowing the correct treatment of high photon energies and electron temperatures. We show new reflection spectra computed with this model, and discuss the improvements achieved in the reproducing the correct shape of the Compton hump, the discrepancies with previous calculations, and the expected impact of these new models in the interpretation of observational data.

description: As it is well known for stiff equations of state an existence of neutron stars with masses $\ga 2 M_{\sun}$ is possible. Especially interesting possibility is opened if the equation of state based on the Skyrme theory is realized in nature. This equation of state was proposed recently by Ouyed and Butler. We discuss different channels of formation of massive rapidly rotating neutron stars. We use a population synthesis code to estimate numbers of massive neutron stars on different evolutionary stages. A neutron star increases its mass by accretion from a secondary companion. Significant growth of a neutron star mass due to accretion is possible only for certain values of initial parameters of the binary. In this paper we show that significant part of massive neutron stars with $M\ga 2 M_{\sun}$ can be observed as millisecond radio pulsars, as X-ray sources in pair with white dwarfs, and as accreting neutron stars with very low magnetic fields.

The laser reveals the vertical movement of an individual Zirconia-Ytria stabilized 2mm ball at the surface of a weakly excited 3D granular matter bed. The stochastic realizations are measured from the top of the container. Then, power spectra measurements reveal the different cooperative dynamics of the fluidized gap. We also carried out measurements for one steel ball and many balls in 1D and 3D systems. We fit the measured different regimes with generalized Langevin pictures. We introduce a fractional temporal operator to characterize the ensemble of dissipative particles which cannot be represented by a single Langevin particle in a complex fluid.

description: The effect of Cu-doping at Mn-site on structural, magnetic and transport properties in electron-doped manganites La0.85Te0.15Mn1-xCuxO3 has been investigated. Based on the analysis of structural parameter variations, the valence state of the Cu ion in Cu-doped manganites is suggested to be +2. All samples undergo the paramagnetic-ferromagnetic (PM-FM) phase transition. The Curie temperature decreases and the transition becomes broader with increasing Cu-doping level, in contrast, the magnetization magnitude of Cu-doping samples at low temperatures increase as x \leq 0.15. The insulator-metal (I-M) transition moves to lower temperatures with increasing Cu-doping content and disappears as x > 0.1. In addition, the higher temperature resistivity r peak in double-peak-like r(T) curves observed in no Cu-doping sample is completely suppressed as Cu-doping level x = 0.1 and r(T) curve only shows single I-M transition at the low temperature well below . The results are discussed according to the change of magnetic exchange interaction caused by Cu-doping.

description: Let G be any abelian group and {a_sG_s}_{s=1}^k be a finite system of cosets of subgroups G_1,...,G_k. We show that if {a_sG_s}_{s=1}^k covers all the elements of G at least m times with the coset a_tG_t irredundant then [G:G_t]\le 2^{k-m} and furthermore k\ge m+f([G:G_t]), where f(\prod_{i=1}^r p_i^{alpha_i})=\sum_{i=1}^r alpha_i(p_i-1) if p_1,...,p_r are distinct primes and alpha_1,...,alpha_r are nonnegative integers. This extends Mycielski's conjecture in a new way and implies a conjecture of Gao and Geroldinger. Our new method involves algebraic number theory and characters of abelian groups.

description: This paper examines the performance of rural groups in Kenya and addresses the methodological issues and challenges faced in doing this, and presents the empirical evidence regarding various hypothesized explanatory factors for relative performance levels. Eighty-seven groups and 442 households were surveyed using several approaches. Various performance measures were tested. Both descriptive analysis and regression models were used to gain a better understanding of the group-level and household-level factors that explain performance. Collective action is desired and practiced for a large number of tasks. The findings highlight the incredible number, diversity and dynamic nature of groups in the highlands of Kenya (and we suspect this finding is not terribly unique to this region). Assessing and comparing performance across a range of group activities is wrought with difficulties related to measurement and standardization. Focusing on groups undertaking similar activities makes it easier to delve more deeply into performance drivers. The empirical analysis focused on the effect of group structural variables (e.g. its size) on performance. We found that choice of performance measure and level at which it is measured (e.g. household, group) matters when it comes to trying to explain the variability in that measure. An analysis across different types of groups engaged in exactly the same activity (tree nurseries) found that predicted group performance was not linked to any easy-to-measure group characteristic, implying that for this task dissemination need not be targeted towards particular types of groups. Looking more broadly at a range of activities, we found that structural factors had varied results.

description: We propose a zero-point photometric calibration of the data from the ACS/WFC on board the Hubble Space Telescope, based on a spectrum of Vega and the most up to date in-flight transmission curves of the camera. This calibration is accurate at the level of a few hundredths of a magnitude. The main purpose of this effort is to transform the entire set of evolutionary models by Pietrinferni et al. (2004) into a simple observational photometric system for ACS/WFC data, and make them available to the astronomical community. We provide the zero points for the most used ACS/WFC bands, and give basic recipes for calibrating both the observed data and the models. We also present the Colour Magnitude Diagram (CMD) from ACS data of 5 Galactic globular clusters, spanning the metallicity range -2.2

description: The last decade has seen the emergence of a number of innovative community level initiatives in Asia, Africa and Latin America for agrobiodiversity development and conservation. Traditional knowledge systems form and integral part of many of these programs. However, there is still a considerable lack of awareness of the importance of traditional agrobiodiversity knowledge systems and of the successes of these new initiatives within formal science institutions. This paper will address a few issues that will need special attention if the successes of the new programs are to be consolidated and their developments shared in a broader perspective. The paper argues that further research is needed inter alia on: (a) approaches to encourage enable inter-cultural recognition and acceptance; (b) specific adjustments needed of national agricultural policy and national agricultural research systems to become supportive of local plant genetic resource management, and (c) different options for protection of traditional knowledge and of collective systems for conservation and development of biodiversity in a wider, non-IPR sense.
CFT in AdS and boundary RG flows

description: Using the fact that flat space with a boundary is related by a Weyl transformation to anti-de Sitter (AdS) space, one may study observables in boundary conformal field theory (BCFT) by placing a CFT in AdS. In addition to correlation functions of local operators, a quantity of interest is the free energy of the CFT computed on the AdS space with hyperbolic ball metric, i.e. with a spherical boundary. It is natural to expect that the AdS free energy can be used to define a quantity that decreases under boundary renormalization group (RG) flows. We test this idea by discussing in detail the case of the large $N$ critical $O(N)$ model in general dimension $d$, as well as its perturbative descriptions in the epsilon-expansion. Using the AdS approach, we recover the various known boundary critical behaviors of the model, and we compute the free energy for each boundary fixed point, finding results which are consistent with the conjectured $F$-theorem in a continuous range of dimensions. Finally, we also use the AdS setup to compute correlation functions and extract some of the BCFT data. In particular, we show that using the bulk equations of motion, in conjunction with crossing symmetry, gives an efficient way to constrain bulk two-point functions and extract anomalous dimensions of boundary operators.
