ENVIRONMENT AND POPULATION PRESSURE ON SCARCE FARMLAND OF  SUBSISTENCE FARMING COMMUNITY: A CASE STUDY FROM DITA WOREDA,  GAMO GOFA ZONE, SOUTH WESTERN ETHIOPIA
Creators: name: Ulgo, Tepa
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: Population  Pressure  and  Farm  Land  are  interdependent  variables  of  subsistence  farming
community.  However,  identification  of  the  numerous  factors  that  determine  the  abilities  of
rural  household’s  choice  of  livelihood  strategies  in  Ethiopia  has  received  little  attention
despite its increasing threat over the poor.
Though the linkages are mediated by many complex and often context-specific factors, there is
strong evidence that dependence on natural resources intensifies when households lose human
and  social  capital  through  adult  morbidity  and  mortality,  and  qualified  evidence  for  the
influence  of  environmental  factors  on  household  decision-making  regarding  fertility  and
migration. Two decades of research on lifecycles and land cover change at the farm level have
yielded a number of insights about how households make use of different land-use and natural
resource  management  strategies  at  different  stages.  Moreover,line  running  throughout  the
review is the importance of managing risk through livelihood diversification, ensuring future
income secur ity, and culture-specific norms regarding appropriate and desirable activities and
demographic responses.
This  research  was  therefore  proposed  with  the  aim  of  generating  location  specific  data  on
population  pressure  and  farm  land  scarcity  of  subsistence  farming  community  and  its
determinants  in  Dita  Woreda  of  Gamo  highland,  southern  Ethiopia.  A  two  stage  stratified
random  sampling  technique  was  employed  to  select  1897  household  heads  from  the  total
human population of 15697 in the three sample kebeles(Ganakare, W/daycha and Tsela) and a
sample size of 152 were taken. In percentage, sample population and sample size were 12.08%
and  8%  respectively.  Data  was  collected  using  key  informant  interview,  focus  group
discussion and interview schedule.

description: We review what we consider to be the minimal model of quantized conductance in a finite interacting quantum wire. Our approach utilizes the simplicity of the equation of motion description to both deal with general spatially dependent interactions and finite wire geometry. We emphasize the role of two different kinds of boundary conditions, one associated with local "chemical" equilibrium in the sense of Landauer, the other associated with screening in the proximity of the Fermi liquid metallic leads. The relation of our analysis to other approaches to this problem is clarified. We then use our formalism to derive a Drude type expression for the low frequency AC-conductance of the finite wire with general interaction profile.

INDIGENOUS KNOWLEDGE OF SOIL FERTILITY MANAGEMENT  PRACTICES TO CROP PRODUCTIVITY: A CASE OF CHENCHA  WOREDA, GAMO GOFA ZONE, SNNPRS.
Creators: name: GENESHA MADA
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: In chencha  woreda, indigenous soil  fertility management practices, are mainly agronomic and
structural systems, which have supported one of the densest rural populations in rural Ethiopia
since immemorial. Currently in this area, indigenous soil fertility management practiced are use
of manure, agro forestry, crop rotation, intercropping, fallow land, and structural soil fertility
management  practices  such  as  soil  bund  and  terrace.  The  main  objective  of  the  study  was  to
examine the indigenous soil fertility management practices of rural farm  household in the area.
The  collected  data  whether  household  survey,  focus  group  discussion,  interview  or  field
observation  were  analyzed  qualitatively  and  quantitatively,  and  that  showed  a  remarkably
existence  of  indigenous  soil  fertility  management  practices  like  agronomic  and  structural.  In
addition  to  this,  tilling  on  time,  tilling  during  dry  sun,  cropping  with  manure  before  rotating
pulses,  use  of  ash  mixing  with  cattle  manure,  pulled-weeds  and  hoe-cut  were  identified  as
fertility  management  practices.  The  data  revealed  that  fallowing  have  gradually  phased  out
while crop rotation has carried out based on crop type in dega agro ecology and based on need
of  farmer  in  woynadega  agro  ecology.  Farmers  perceived  that  indigenous  soil  fertility
management practices are better although it affected by land size, sex, age and education level
in addition to insignificant factors like reduction of grazing land, family income, introduction of
modern fertilizer and peoples outlook in both agro ecologies. And all variables were tested by
chi  square   to  understand  significant  association  .To  the  sustainability  of  this  indigenous  soil
fertility  management  practices,  it  might  be  integrated  in  to  modern  agricultural  system,  the
structural techniques should be strengthen and  fertilizer preparation technologies disseminate to
other smallholder farmers as well as local people should be acknowledged.

description: Context. The lack of sub-Jovian planets on orbits of $P_{\rm orb} < 3$ days is a puzzling aspect of galaxy formation with regard to the distribution of exoplanets whose origins are currently unresolved. Aims. The possible explanations behind the formation of the sub-Jovian or Neptunian desert include several scenarios that can lead to different shapes for the boundary, predicting various dependencies between the position of the boundary and the stellar parameters. Methods. We explored the exoplanet distribution in various 2D and 3D projections, revealing the stellar-dependent substructures in the $P_{\rm orb}-M_{P}$ and the $P_{\rm orb}-R_{P}$ parameter plane. Results. We demonstrate that the upper boundary includes a range of planets, namely, inflated hot Jupiters and normal hot Jupiters, in the two parameter planes, respectively. We confirm the dependence of the boundary on several stellar parameters and, based on a fuzzy clustering analysis, we provide quantitative formulae for the dependencies in groups of smaller and larger planets. The overall period-radius distribution shows chemical substructures as well, with the boundary being dependent on volatiles and alpha-elements, alongside marginal (to none) dependence found for refractory elements. Conclusions. These findings confirm multiple plausible causes for the formation of the desert, particularly preferring those scenarios related to the irradiation-driven loss of the atmospheres of moderately massive planets as the predominant process in shaping planetary distributions.

description: Successful implementation of oil spill segmentation in Synthetic Aperture Radar (SAR) images is vital for marine environmental protection. In this paper, we develop an effective segmentation framework named DGNet, which performs oil spill segmentation by incorporating the intrinsic distribution of backscatter values in SAR images. Specifically, our proposed segmentation network is constructed with two deep neural modules running in an interactive manner, where one is the inference module to achieve latent feature variable inference from SAR images, and the other is the generative module to produce oil spill segmentation maps by drawing the latent feature variables as inputs. Thus, to yield accurate segmentation, we take into account the intrinsic distribution of backscatter values in SAR images and embed it in our segmentation model. The intrinsic distribution originates from SAR imagery, describing the physical characteristics of oil spills. In the training process, the formulated intrinsic distribution guides efficient learning of optimal latent feature variable inference for oil spill segmentation. The efficient learning enables the training of our proposed DGNet with a small amount of image data. This is economically beneficial to oil spill segmentation where the availability of oil spill SAR image data is limited in practice. Additionally, benefiting from optimal latent feature variable inference, our proposed DGNet performs accurate oil spill segmentation. We evaluate the segmentation performance of our proposed DGNet with different metrics, and experimental evaluations demonstrate its effective segmentations.
Long-term periodontal changes during oral appliance treatment for sleep apnea
Creators: name: Heda, Piyush
Publisher: name: University of British Columbia
Year: 2019

description: Background: 2 to 4% of estimated population within the age range of 30 to 60 years is diagnosed with obstructive sleep apnea (OSA). Contemporary management of OSA commonly involves continuous positive airway pressure (CPAP) or oral appliance (OAm) therapy. One of the side effects of long-term OAm wear is mesialization of mandibular dentition resulting in the proclination of mandibular incisors. Similar movement of incisors following orthodontic treatment has been associated with gingival recession. Purpose: The purpose of this retrospective, in-vivo, clinical and cephalometric observational study is to evaluate the periodontal changes associated with OAm treatment of 4.5 or more years, in individuals with OSA. Research Design: Patients consecutively treated between 2004 to 2014 at UBC Dental Sleep Clinic and an affiliated private practice were screened. Eligible subjects were followed up where periodontal exam was performed. A lateral cephalogram and impressions were also obtained. Clinical crown height was measured on study models. Periodontal exam included PSR (periodontal screening and recording), plaque index, gingival bleeding index, probing pocket depths and facial gingival margin thickness, in addition to clinical attachment level (CAL), recession and width of attached gingiva. Baseline (T1) and follow up (T2) data was compared. Results: A total of 21 patients (15 males, mean age 57.4±12.0 y.o) were enrolled, with a mean treatment length of 7.6±3.3 years (range = 4.5 to 14.3 years). At follow up all patients presented with good oral hygiene with mean plaque index of 0.4 and bleeding index of 4.1%. PSR data confirmed absence of active periodontal disease. For mandibular anterior teeth, mean probing depth was 1.4±0.5 mm, recession was -0.6±1.1 mm and CAL was 0.8±1.0 mm. Compared to baseline there was significant proclination of mandibular incisors (mean increase in IMPA of 5.1º) with the continued use of OAm. Clinical crown height did not change (mean increase of 0.01 mm) over the evaluated time period. Conclusions: The inclination of mandibular incisors increases significantly with the use of mandibular advancing oral appliance in OSA patients. The positional changes in these teeth was not associated with any measured evidence of increase in periodontal disease or increased clinical crown height.

description: The Cosmology Large Angular Scale Surveyor (CLASS) is a polarization-sensitive telescope array located at an altitude of 5,200 m in the Chilean Atacama Desert and designed to measure the polarized Cosmic Microwave Background (CMB) over large angular scales. The CLASS array is currently observing with three telescopes covering four frequency bands: one at 40 GHz (Q); one at 90 GHz (W1); and one dichroic system at 150/220 GHz (HF). During the austral winter of 2022, we upgraded the first 90 GHz telescope (W1) by replacing four of the seven focal plane modules. These new modules contain detector wafers with an updated design, aimed at improving the optical efficiency and detector stability. We present a description of the design changes and measurements of on-sky optical efficiencies derived from observations of Jupiter.

description: Digital quantum simulation of electron-phonon systems requires truncating infinite phonon levels into $N$ basis states and then encoding them with qubit computational basis. Unary encoding and the more compact binary/Gray encoding are the two most representative encoding schemes, which demand $\mathcal{O}(N)$ and $\mathcal{O}(\log{N})$ qubits as well as $\mathcal{O}(N)$ and $\mathcal{O}(N\log{N})$ quantum gates respectively. In this work, we propose a variational basis state encoding algorithm that reduces the scaling of the number of qubits and quantum gates to both $\mathcal{O}(1)$ for systems obeying the area law of entanglement entropy. The cost for the scaling reduction is a constant amount of additional measurement. The accuracy and efficiency of the approach are verified by both numerical simulation and realistic quantum hardware experiments. In particular, we find using one or two qubits for each phonon mode is sufficient to produce quantitatively correct results across weak and strong coupling regimes. Our approach paves the way for practical quantum simulation of electron-phonon systems on both near-term hardware and error-corrected quantum computers.

description: We consider the class of four-dimensional N=2 gauged supergravities whose maximally symmetric ground states leave only one of the two supersymmetries intact. For these theories we derive the low-energy effective action below the scale of partial supersymmetry breaking and compute the N=1 couplings in terms of the N=2 'input data'. We show that this effective action satisfies the constraints of N=1 supergravity in that its sigma-model metric is Kahler, while the superpotential and the gauge kinetic functions are holomorphic. As an example we discuss the N=1 effective supergravity of type II compactifications.

description: Land  use  and  land  cover  change  constitute  serious  problem  in  many  part  of  Ethiopia.  So,
Lomate  Water  Shed  is  not  exceptional  to  this  type  of  problems.  Agricultural  practices,
grazing, deforestations and steep slope cultivation are responsible factors for land use and
land cover in the study area. Thus, this  study  aimed to assessing the effect of land use and
land  cover  change  on  soil  erosion.  The  study  area  covered  around  16,677  ha  and  can  be typical  of  a  large  part  of  the  district  in  terms  of  topography,  climate,  vegetation,  and
socioeconomic  conditions.The  problem  of  soil  erosion  is  a  difficulty  of  Uba-Debretsehay
district  since  destruction  of  the  environment,  reduction  of  agricultural  productivity  which
related to income and livelihoods are realistic. However, the cumulative effect of soil erosion
in  the  watershed  created  volatile  living  status  for  the  rural  commu nity.Therefore  the
objectives  of  this  study  were  to  assess  the  Effect  of  Soil  Erosion  on  Rural  Livelihoods  of
farmers in the Lomate Watershed, Uba-Debretsehay Woreda, Ethiopia. The methodologies to
study  the  assessment  were  both  primary  and  secondary  data  was  utilized.Observations,
Interviews  Focus Group Discussions (FGDs),Document Review and Analysis and an attempt
was made to identify soil erosion effect on livelihoods, for which the change of environment
was  evaluated  in  deep.  Since,  the  land  use  land  cover  of  1995  G.C  to  2015  G.C  were
examined  by  applying  GIS  and  ERDAS  imagine  Software’s  to  see  the  change  of  the
watershed over the past 21 years.The results shows that during the last 21 years, forest cover
from 371 ha almost decreased by 15.43 ha per  annum that is 324 ha in twenty first year. The
Communal land cover was 3136 ha, but it decrease annually almost41.7 ha, and totally in
twenty first year it decreased to 876 ha, and the shrub land also decreased almost 91.14 ha,
annually and in twenty first  years it goes down to 1914 ha,. Oppositely the bare land by 816
ha,  in  the  twenty  first  years.  Then  this  indicates  that  the  large  hectare  of  forest  land,
communal  land  and  the  shrub  land  converted  to  farm  land.  Shrub-grassland  is  the  most
converted cover  type during the entire study period. In the21 years, the original grassland
cover was existed  at the base year but cultivation land increased starting from the first year
of study, but agricultural product decline in all 21 years.  Limited availability and  extinction
of some tree/shrub species is also reported and research is required  to quantify changes and
understand the real impacts brought about.

description: The author considers the planar rotational motion of the mathematical pendulum with its pivot oscillating both vertically and horizontally, so the trajectory of the pivot is an ellipse close to a circle. The analysis is based on the exact rotational solutions in the case of circular pivot trajectory and zero gravity. The conditions for existence and stability of such solutions are derived. Assuming that the amplitudes of excitations are not small while the pivot trajectory has small ellipticity the approximate solutions are found both for high and small linear damping. Comparison between approximate and numerical solutions is made for different values of the damping parameter.

description: We derive and study the equations of motion of the Born-Infeld extension of New Massive Gravity for globally and asymptotically (anti-)de Sitter spaces, and show that the assumptions of the null-energy condition and holography (that bounds the c-function) lead to two simple c-functions one of which is equivalent to the c-function of Einstein's gravity. We also show that, at the fixed point, the c-function gives the central charge of the Virasoro algebra and the coefficient of the Weyl anomaly up to a constant.

Psychometrics & post-data analysis : a software implementation for binary logistic regression in jamovi
Creators: name: Friesen, Lucas
Publisher: name: University of British Columbia
Year: 2019

description: Differential item functioning (DIF) analysis is an invaluable tool for providing evidence that a test or measure is functioning as intended, and has been used extensively to show evidence that the items of tests are (not) favouring one group of test takers over another. Beyond evidence (for) against differential performance of items, DIF analysis provides extremely useful validation evidence in psychosocial measures because its application need not be limited to simple cases like, for example, detecting DIF based on a binary gender classification. However, the technical knowledge requirements of DIF analysis software can be prohibitively high in some research settings. The jamovi suite “Psychometric Post-Data Analysis” has been developed with a module for performing DIF analysis on dichotomously scored items using a generalized linear model framework (GLIM) that incorporates the GLIM family of methods for detecting DIF in a user- friendly interface. In addition, the idea of Type-M errors (Gelman & Carlin, 2014) was adapted and expanded to the DIF context, and then incorporated into the module. This tool is especially useful in the context of low-powered research settings. The goal of developing this module is to encourage the use of the GLIM framework for DIF analysis in the broader psychosocial measure validation praxis by lowering the technical barrier to assessing DIF and increasing the interpretability of DIF analysis results via post-data analytic techniques.

description: We run stochastic simulations of the spatial version of the rock-paper-scissors game, considering that individuals use sensory abilities to scan the environment to detect the presence of enemies. If the local dangerousness level is above a tolerable threshold, individuals aggregate instead of moving randomly on the lattice. We study the impact of the locally adaptive aggregation on the organisms' spatial organisation by measuring the characteristic length scale of the spatial domains occupied by organisms of a single species. Our results reveal that aggregation is beneficial if triggered when the local density of opponents does not exceed $30\%$; otherwise, the behavioural strategy may harm individuals by increasing the average death risk. We show that if organisms can perceive further distances, they can accurately scan and interpret the signals from the neighbourhood, maximising the effects of the locally adaptive aggregation on the death risk. Finally, we show that the locally adaptive aggregation behaviour promotes biodiversity independently of the organism's mobility. The coexistence probability rises if organisms join conspecifics, even in the presence of a small number of enemies. We verify that our conclusions hold for more complex systems by simulating the generalised rock-paper-scissors models with five and seven species. Our discoveries may be helpful to ecologists in understanding systems where organisms' self-defence behaviour adapts to local environmental cues.

description: We report on the discovery of a very distant galaxy cluster serendipitously detected in the archive of the XMM-Newton mission, within the scope of the XMM-Newton Distant Cluster Project (XDCP). XMMUJ0044.0-2033 was detected at a high significance level (5sigma) as a compact, but significantly extended source in the X-ray data, with a soft-band flux f(r<40")=(1.5+-0.3)x10^(-14) erg/s/cm2. Optical/NIR follow-up observations confirmed the presence of an overdensity of red galaxies matching the X-ray emission. The cluster was spectroscopically confirmed to be at z=1.579 using ground-based VLT/FORS2 spectroscopy. The analysis of the I-H colour-magnitude diagram shows a sequence of red galaxies with a colour range [3.7 < I-H < 4.6] within 1' from the cluster X-ray emission peak. However, the three spectroscopic members (all with complex morphology) have significantly bluer colours relative to the observed red-sequence. In addition, two of the three cluster members have [OII] emission, indicative of on-going star formation. Using the spectroscopic redshift we estimated the X-ray bolometric luminosity, Lbol = 5.8x10^44 erg/s, implying a massive galaxy cluster. This places XMMU J0044.0-2033 at the forefront of massive distant clusters, closing the gap between lower redshift systems and recently discovered proto- and low-mass clusters at z >1.6.

description: Multiscale entropy (MSE) has been widely used to examine nonlinear systems involving multiple time scales, such as biological and economic systems. Conversely, Allan variance has been used to evaluate the stability of oscillators, such as clocks and lasers, ranging from short to long time scales. Although these two statistical measures were developed independently for different purposes in different fields in the literature, their interest is to examine multiscale temporal structures of physical phenomena under study. We show that, from an information-theoretical perspective, they share some foundations and exhibit similar tendencies. We experimentally confirmed that similar properties of the MSE and Allan variance can be observed in low-frequency fluctuations (LFF) in chaotic lasers and physiological heartbeat data. Furthermore, we calculated the condition under which this consistency between the MSE and Allan variance exists, which is related to certain conditional probabilities. Heuristically, physical systems in nature including the aforementioned LFF and heartbeat data mostly satisfy this condition, and hence the MSE and Allan variance demonstrate similar properties. As a counterexample, an artificially constructed random sequence is demonstrated, for which the MSE and Allan variance exhibit different trends.

description: Chiral multifold fermions are quasi-particles that appear only in chiral crystals such as transition metal silicides in the cubic B20 structure (i.e., the CoSi family), and they may show exotic physical properties. Here we study the injection and shift photoconductivities and also the related geometrical quantities for several types of chiral multifold fermions, including spin-1/2 as well as pseudospin-1 and -3/2 fermions, dubbed as Kramers Weyl, triple point and Rarita-Schwinger-Weyl (RSW) fermions, respectively. We utilize the minimal symmorphic model to describe the triple point fermions (TPF). We also consider the more realistic model Hamiltonian for the CoSi family including both linear and quadratic terms. We find that circular injection currents are quantized as a result of the Chern numbers carried by the multifold fermions within the linear models. Surprisingly, we discover that in the TPF model, linear shift conductivities are proportional to the pseudo spin-orbit coupling and independent of photon frequency. In contrast, for the RSW and Kramer Weyl fermions, the linear shift conductivity is linearly proportional to photon frequency. The numerical results agree with the power-counting analysis for quadratic Hamiltonians. The frequency independence of the linear shift conductivity could be attributed to the strong resonant symplectic Christoffel symbols of the flat bands. Moreover, the calculated symplectic Christoffel symbols show significant peaks at the nodes, suggesting that the shift currents are due to the strong geometrical response near the topological nodes.
Reduced nuclear helicity amplitudes for deuteron electrodisintegration and other processes

description: We extend the original idea of reduced nuclear amplitudes to capture individual helicity amplitudes and discuss various applications to exclusive processes involving the deuteron. Specifically, we consider deuteron form factors, structure functions, tensor polarization observables, photodisintegration, and electrodisintegration. The basic premise is that nuclear processes at high momentum transfer can be approximated by tree graphs for point-like nucleons supplemented by empirical form factors for each nucleon. The latter represent the internal structure of the nucleon, and incorporate nonperturbative physics, which can allow for early onset of scaling behavior. The nucleon form factors are evaluated at the net momentum transfer experienced by the given nucleon, with use of $G_E$ for a no-flip contribution and $G_M$ for a helicity-flip contribution. Results are compared with data where available. The deuteron photodisintegration asymmetry $Σ$ is obtained with a value of $Σ(90^\circ)\simeq -0.06$, which is much closer to experiment than the value of -1 originally expected. The method also provides an estimate of the momentum transfer values required for scaling onset. We find that the deuteron structure function $B$ is a good place to look, above momentum transfers of 10 GeV$^2$.

description: After the initial moments of political protest have passed, urban protest movements and neighbourhood initiatives often face the challenge of establishing a sustainable organizing structure in their neighbourhoods and of creating long-lasting collaborations, including maintaining relations among various participants and heterogeneous political actors in the city. This paper analyses the political practice of Kotti & Co, an urban neighbourhood initiative that has been active in political struggles pertaining to social housing and displacement and working against racism and neoliberal urban politics in the super-diverse city of Berlin. In the larger context of urban protest movements since 2011, the initiative managed to overcome a series of political challenges and to build a long-lasting organizing practice. The authors identify Kotti & Co as a ‘community of struggle’ that was able to foster a lasting movement through three elements of sustainability. The protest first managed to build bridges across and beyond its members’ differences (class, migration background, sexual orientation) by finding a common set of political demands and social practices as well as by establishing collective place-based subjectivities. These place-based subjectivities have contributed to overcoming conventional identity politics by forming a new kind of political identity through the struggle itself.

description: A direct CP asymmetry in inclusive semileptonic B_(s) decays vanishes by CPT to lowest order in weak interactions. Calculating the asymmetry at second order weak interactions in the Cabibbo-Kobayashi-Maskawa framework we find A_{sl} = (-3.2 \pm 0.9) x 10^{-9}. A maximal asymmetry which is two orders of magnitude larger is estimated in a left-right symmetric model. This quite generic upper bound implies negligible effects on wrong-sign lepton asymmetries in B^0 and B_s decays.

description: This paper presents the first simultaneous measurement of the quasielastic-like neutrino-nucleus cross sections on C, water, Fe, Pb and scintillator (hydrocarbon or CH) as a function of longitudinal and transverse muon momentum. The ratio of cross sections per nucleon between Pb and CH is always above unity and has a characteristic shape as a function of transverse muon momentum that evolves slowly as a function of longitudinal muon momentum. The ratio is constant versus longitudinal momentum within uncertainties above a longitudinal momentum of 4.5GeV/c. The cross section ratios to CH for C, water, and Fe remain roughly constant with increasing longitudinal momentum, and the ratios between water or C to CH do not have any significant deviation from unity. Both the overall cross section level and the shape for Pb and Fe as a function of transverse muon momentum are not reproduced by current neutrino event generators. These measurements provide a direct test of nuclear effects in quasielastic-like interactions, which are major contributors to long-baseline neutrino oscillation data samples.
