PROBLEMS  AND  EFFECTIVENESS  OF  FARMERS`  TRAINING  CENTERS  IN SOUTHERN ETHIOPIA, THE CASE OF ARBEGONA WOREDA, SIDAMA ZONE
Creators: name: HAILU AMAJE
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: The current concerted efforts of Ethiopian government for the establishment of farmers` training
centers in every peasant associations is an emerging agricultural extension strategy aiming at
developing human capital through training to enhance farmers’ knowledge and practical skills
for  improving  agricultural  production  and  productivity.  However,  the  present  status  and
performance  of  farmers`  training  centers  and  the  constraints  that  hinder  farmers`  training
centers  in  effective  functioning  of  modern  ways  of  farming  system  have  not  been  studied
empirically  and  assessed  in  depth  for  taking  appropriate  action  in  time.  This  study  was
conducted  to  assess  the  current  performance  of  farmers`  training  centers  in  relation  to  its
structure  and  function,  to  examine  the  community  participation  on  farmers`  training  centers
based  activities,  to  identify  opportunities  and  constraints  of  farmers`  training  centers  and  to
analyze the relevance and effectiveness of farmers training center based training. The study was
based  on  descriptive  survey  design  encompassing  both  qualitative  and  quantitative  data  and
multi-stage  sampling  procedure  was  employed  to  select  the  sample.  A  total  of  128  sample
respondents and 12 DAs working in farmers` training centers were selected. Interview schedules,
focus group discussions, key informant interviews and personal observations were conducted for
quantitative and qualitative data collection.  The data were analyzed by using simple descriptive
statistics  such  as  percentage,  frequency,  tables  and  charts.  Qualitative  data  were  analyzed
through interpretation and conceptual generalization.  The findings of this study indicate that all
sample  farmers  training  centers  do  not  fulfilled  by  the  necessary  facilities  and  teaching
materials. There are social, institutional and economical problems that hinder the performances
of farmers training centers. The woreda bureau of agriculture and rural development and every
concerned  stakeholder  should  take  into  consideration  the  institutional,  social  and  economic
constraints affected the effective functioning of farmer training centers.
Will’s Notebook : the art of learning from experience and listening
Creators: name: Murphy, David Cotter
Publisher: name: University of British Columbia
Year: 2019

description: This dissertation is an inquiry into how experience and listening can be used in creative production to improve teaching and learning through attunement. I use an arts-based research approach to develop two creative productions. The first is a story book (Will’s Notebook) that tells a tale of my journey, the second is a suite of soundscape compositions (The Cotter Suite) that represents this journey musically. Through hermeneutic reflection of experience, acceptance of complexity and uncertainty, and self-care, a theoretical framework is developed to consider how artistic practice and creative production can be sources of educational research and development. The conceptualization of artistic practice and creative production as part of my own currere connects curriculum studies and educational research to arts-based practice for the improvement of teaching and learning.

description: In Brans-Dicke theory a non-linear self interaction of a scalar field allows a possibility of realizing the late-time cosmic acceleration, while recovering the General Relativistic behavior at early cosmological epochs. We extend this to more general modified gravitational theories in which a de Sitter solution for dark energy exists without using a field potential. We derive a condition for the stability of the de Sitter point and study the background cosmological dynamics of such theories. We also restrict the allowed region of model parameters from the demand for the avoidance of ghosts and instabilities. A peculiar evolution of the field propagation speed allows us to distinguish those theories from the LCDM model.

description: The recently claimed observations of non-negligible amounts of 6Li in old halo stars have renewed interest in the Big-Bang Nucleosynthesis (BBN) of 6Li. One important ingredient in the predicted BBN abundance of 6Li is the low-energy 2H(alpha,gamma)6Li cross section. Up to now, the only available experimental result for this cross section showed an almost constant astrophysical S-factor below 400 keV, contrary to theoretical expectations. We report on a new measurement of the 2H(alpha,gamma)6Li reaction using the break-up of 6Li at 150 A MeV. Even though we cannot separate experimentally the Coulomb contribution from the nuclear one, we find clear evidence for Coulomb-nuclear interference by analyzing the scattering-angular distributions. This is in-line with our theoretical description which indicates a drop of the S_24-factor at low energies as predicted also by most other models. Consequently, we find even lower upper limits for the calculated primordial 6Li abundance than before.

description: We report first multicolor polarimetric measurements (UBV bands) for the hot Jupiters HD189733b and confirm our previously reported detection of polarization in the B band (Berdyugina et al. 2008). The wavelength dependence of polarization indicates the dominance of Rayleigh scattering with a peak in the blue B and U bands of ~10^-4+/-10^-5 and at least a factor of two lower signal in the V band. The Rayleigh-like wavelength dependence, detected also in the transmitted light during transits, implies a rapid decrease of the polarization signal toward longer wavelengths. Therefore, the nondetection by Wiktorowicz (2009), based on a measurement integrated within a broad passband covering the V band and partly B and R bands, is inconclusive and consistent with our detection in B. We discuss possible sources of the polarization and demonstrate that effects of incomplete cancellation of stellar limb polarization due to starspots or tidal perturbations are negligible as compared to scattering polarization in the planetary atmosphere. We compare the observations with a Rayleigh-Lambert model and determine effective radii and geometrical albedos for different wavelengths. We find a close similarity of the wavelength dependent geometrical albedo with that of the Neptune atmosphere, which is known to be strongly influenced by Rayleigh and Raman scattering. Our result establishes polarimetry as a reliable means for directly studying exoplanetary atmospheres.

description: We present a new approach to the reduction of one-loop amplitudes obtained by reconstructing the tensorial expression of the scattering amplitudes. The reconstruction is performed at the integrand level by means of a sampling in the integration momentum. There are several interesting applications of this novel method within existing techniques for the reduction of one-loop multi-leg amplitudes: to deal with numerically unstable points, such as in the vicinity of a vanishing Gram determinant; to allow for a sampling of the numerator function based on real values of the integration momentum; to optimize the numerical reduction in the case of long expressions for the numerator functions.

description: The  purpose  of  this  study  was  to  assess  the  status  of  community  participation  in  the
rehabilitation of degraded land. In order to achieve the objective of the study, both primary and
secondary  data  were  generated  by  employing  qualitative  and  quantitative  data.  Stratified
sampling  technique  was  used  to  select  sample  kebeles.  Accordingly  six  rural  kebeles  were
selected  two ago ecological zone  by purposively. Field survey was  also  conducted to collect the
necessary data from 194 sample households, which were selected from six rural kebeles by using
simple  random  sampling  techniques.  Interview  and  observation  were  also  used  to  collect  the
relevant data.  The data were analyzed using descriptive statistic such as percentage, frequency,
tables, figure, and Chi-square test among independent and dependent variables. All statistical
manipulations were done by SPSS 16.0 versions for windows. The result of the study revealed
that  majority  of  the  farmers  hold  moderate  level  of  participation  on  the  land  rehabilitati on
practices, governmental experts are more participants in the practices.  Tree planting, soil bund,
contour plowing and closure of grazing land  were widely used land rehabilitation practices in
the  study  area.  The  study  also  revealed  that  there  was  statistically  significant  association  in
participation of farmers in terms of age, educational back ground, family size and income level.
It shows that  famer’s relatively young age, attended primary school, large family size and high
income level farmers  found  to have better participation about the land rehabilitation practices.
Based  on  the  findings  it  was  recommended  that,  continuous  training  and  experience  sharing
program, immediate action to increase the number of literate persons, to practicing  compatible
practices for the agro climatic zone  and extending effective practices,  create opportunities for
alternative  means  of  livelihood  and  promoting  NGOs  effort  to  involve  in  land  rehabilitation
practices in the highly degraded area.

description: Participatory Sustainable management of communal forest is the key to manage  forests
for the long terms and to certify that all uses derived from the forest meet present day
need without affecting the ability of future generations to satisfy their own requirements.
However,  the  communal  forests  are  degraded  due  to  human  interferences,  and  the
management  practices  were  not  attaining  the  goal  anticipated.  In  this  study,  the
constraints  to the sustainable  management of communal forest were assessed.  Purposive
sampling techniques were employed to reach at  the final unit of sample size.  Similarly
sample  kebeles  were  selected  by  employing  purposive  and  proportional  quota.  The
required  data  for  this  study  were  obtained  from  both  primary  and  secondary  data
sources. The finding indicated that the current condition of communal forest is heavily
disturbed and increased; causes for the removal of communal forest were identified as
agriculture,  fuel  wood,  sustainable  management  of  communal  forest,  decision  making
power on the issue of illegal users of communal forests, and  respondents’ benefits from
communal  forest  in  the  study  area.  The  research  result  showed  that  the  relationship
between  the  respondents  age  group,  gender,  educational  status,  respondents’  distance
from  market  and  forest  were  significant  with  participatory  sustainable  management  of
communal forest. In general from this study, the illegal act in using the communal forests
led to the communal forest degradation increased in the study area.
FARMERS’  PERCEPTION  OF  SOIL  EROSION  AND  MANAGEMENT  PRACTICES.  A  CASE  OF  ARBEGONA  WOREDA  “WOINA-DEGA”  AGRO-ECOLOGY ZONE, SIDAMA ZONE, SNNPRS
Creators: name: TEKLU ADULA

description: Soil erosion is a complex process that involves the detachment, movement and deposition
of soil particles mainly by wind and water  but the problem is not noticed  and perceived
by all farmers at  the same fashion and level.  Thus, the  study is aimed to assess the status
of farmers’  perception  of  soil  erosion  and  management  practices  in  Arbegona  woreda
woina-dega  agro-ecology  zone.  A  two-stage  systematic  sampling  procedure  was
employed  to  select  four  sample  kebeles  and  175  sample  household  heads  to  collect
primary  data.  Interview  and  observation  were  also  used  to  collect  the  relevant  data.
Descriptive  statistics,  chi-square  analysis  and  Likert  scale  were  employed  to  show  the
frequency  and  percentage distribution of respondents.    As the study has  been  shown the
farmers  perception  of  difficulty  for  farming,  desertification,  poverty  and  economic
backwardness  and  increase  the  requirement  for  fertilizer  as  the  consequences  of  soil
erosion  were found  relatively less and not reported by majority of the  respondents except
few educated  farmers.  Concerning the perception to soil erosion management practices,
closure  of  grazing  land,  windbreak,  fallowing  and  mulching  perhaps  are  said  to  have
been  the  least  perceived  as  management  practices  used  by  farmers  except  those  who
attended  primary  and  secondary  education.  On  the  other  hand,  tree  planting,  contour
plowing,  terracing  and  organic  manure  were  indicated  as  the  frequently  used  soil
management  practices.  Windbreak,  fallowing,  closure  of  grazing  land,  rotational
grazing,  mixed  cropping,  and  making  waterways  were  also  another  important  soil
management practices but not used by  the majority of the  respondents except educated
farmers.  Pertaining the sources of information for farmers extension agents and training
were  found as  the most important  one.  As  the chi-square analysis has  been shown age,
education,  family  size,  income  level,  and  information  access  were  major  factors  that
influence  perception  of  farmers.  Therefore,  continuous  education,  training  and
disseminating information is very important to arouse farmers’ perception of soil erosion
and  management  practices  by  considering  their  current  perception  level  in  the  study
area.

As  resource  degradation  is  a  critical  problem,  conservation  issues  have  become  vital  in
Ethiopia. Soil erosion has been environmental problems for a  long period of time in the study
area, perhaps, causing environmental problems such as desertification, soil fertility reduction,
depletion  of  productive  resources,  agricultural  land  deterioration,  food  insecurity,  damage  of
public properties, etc. Thus,  the study is to identify the determinant factors that affect CUSCMs
in Horo District, Western Ethiopia.  Stratified and systematic random sampling techniques were
employed to reach at the final unit of sample size. Study area is five kebeles in the Horo  woreda
were selected by agro-ecologies zone and household heads.  From this sample, the data required
for  this  study  were  obtained  from  both  primary  and  secondary  data  sources.  A  total  of  181
households  were  interviewed,  field  observation  and  questionnaire  was  undertaken  through
transect walks.    Qualitative primary data was analyzed by using qualitative techniques (verbal
description).  Data  was  analyzed  using  descriptive  statistics,  quantitative  primary  data,  SPSS,
Pearson Correlation coefficient of the techniques. In addition,  Simple  linear regression models
were  employed  to  analyze  the  influence  of  independent  variables  on  dependent  variables.  The
finding  indicated  Farmer’s positive attitude (PSTVATDE) towards  SCPs, farmer’s perception of
effectiveness (PEREFCTVNESS) of SCPs, farmers’ participation in SC training (TRNNG), high
erosion problem (HERPRBLM) on farm land, level of contact with development agent (DAVST),
steep slope (STEPSLP), farmer’s perception of  erosion as problem (PERCEROSN), educational
level (EDCTNALLVL) and land certificate (LNDCRTFCTE) have a significant positive in fluence
on  farmers’  CUSCMs.  High  plot  productivity  (HIGHPLTPRDCVTY),  farming  experience
(FRMNGEXPENCE),  application  of  inorganic  fertilizer  (APCINOFERTLZR),  farm  land  size
(FARMSIZE),  and  age  (AGE)  of  the  house  hold  head  have  insignificant  positive  influence  on
farmers  CUSCMs. Other explanatory variables such as gender (SEX), family size (FAMLYSIZE)
have an insignificant negative influence on farmer’s  CUSCMs.  On the other hand, ISCPs  have
integration with other MSCPs.

Year: 2010

description: In this research, we study the optimization challenges of MANET and cross-layer technique to improve its performance. We propose an adaptive retransmission limits algorithm for IEEE 802.11 MAC to reduce the false link failures and predict the node mobility. We implemented cross layer interaction between physical and MAC layers. The MAC layer utilizes the physical layer information for differentiating false link failure from true link failure. The MAC layer adaptively selects a retransmission limit (short and long) based on the neighbour signal strength and sender node speed information from the physical layer. The proposed approach tracks the signal strength of each node in network and, while transmitting to a neighbour node, if it's received signal strength is high and is received recently then Adaptive MAC persists in its retransmission attempts. As there is high probability that neighbour node is still in transmission range and may be not responding due to some problems other then mobility. In this paper, we evaluate the performance of MANET and show that how our Adaptive MAC greatly improves it. The simulation is done using Network Simulator NS-2.
Parsing and analysis of mass spectrometry data of complex biological and environmental mixtures
Creators: name: Kovalchik, Kevin
Publisher: name: University of British Columbia
Year: 2019

description: The chemical characterization of biological and environmental samples are areas of research which involve the analysis of highly complex chemical mixtures. While the samples from these two fields differ greatly in composition, they present similar challenges. Complex mixtures provide a challenge to the analytical chemist as compounds in the mixture can have matrix effects which interfere with the analysis. Indeed, these interfering compounds may even be analytes themselves. High resolution mass spectrometry, which separates and detects ions based on their mass-to-charge ratio, is a powerful tool in the analysis of such mixtures. The amount of data resulting from such analyses, however, can be intractable to manual analysis, necessitating the use of computational tools. Furthermore, for the data to be reliable it is important that the performance of the mass spectrometer is optimal and consistent, but the complexity of the data again makes manual interpretation of the quality difficult. Thus, there is a need for computational assistance in analysis as well as method optimization and quality control. In Chapter 2:, we present a review of considerations toward the design of a standard mass spectrometry-based method for the quantification of naphthenic acids. The study provides recommendations for how these considerations can be addressed. In Chapter 3:, we describe a computational method of resolving dicarboxylic acids in high resolution mass spectrometry data of mixtures of derivatized naphthenic acid fraction compounds. The study is a proof-of-concept and demonstrates that derivatization-based methods of analyzing these diacid components is feasible but requires further investigation. In Chapter 4: and Chapter 5:, we present two computational tools which assist in method optimization and quality control of Thermo Orbitrap mass spectrometer systems. Chapter 4: presents RawQuant, a software tool which extracts scan quantification and meta data from data-dependent analysis data files from Orbitrap mass spectrometer systems. The tool is designed to inform the user toward method optimization. Chapter 5: presents RawTools, which builds upon RawQuant by adding the ability to track important measures of mass spectrometer performance longitudinally across a multi-run experiment. The tool is demonstrated using a 140-file dataset and provides easy visual monitoring of instrument performance.

description: We consider waves propagating in a randomly layered medium with long-range correlations. An example of such a medium is studied in \citeMS and leads, in particular, to an asymptotic travel time described in terms of a fractional Brownian motion. Here we study the asymptotic transmitted pulse under very general assumptions on the long-range correlations. In the framework that we introduce in this paper, we prove in particular that the asymptotic time-shift can be described in terms of non-Gaussian and/or multifractal processes.

description: We show that vanishing of the sigma-model beta-functions for the metric $g_{μν}$, antisymmetric tensor $B_{μν}$ and dilaton $Φ$ of any string-theory model in $D$ dimensions at tree level can be obtained from a universal effective action, provided that the field combination $\sqrt{-g}e^{-2Φ}$ is non-dynamical. The central-charge deficit term is omitted from the action and appears as an integration constant at the level of the field equations. The analysis is done at leading order in $α'$, i.e. at the two-derivative level in the effective description. It can be extended to incorporate higher order string-loop corrections, Ramond-Ramond forms and moduli fields. In all cases, the non-dynamical field combination turns out to be $\sqrt{-g}\, U$, where $U$ is the effective potential. When certain fluxes are fixed and the moduli fields are stabilized, no cosmological term will arise in the action. Instead, the cosmological constant will appear as an integration constant as in unimodular modifications of general relativity.

description: We have prepared a degenerate gas of fermionic atoms which move in two dimensions while the motion in the third dimension is "frozen" by tight confinement and low temperature. {\it In situ} imaging provides direct measurement of the density profile and temperature. The gas is confined in a defect-free optical potential, and the interactions are widely tunable by means of a Fano--Feshbach resonance. This system can be a starting point for exploration of 2D Fermi physics and critical phenomena in a pure, controllable environment.

description: We study the properties of 10D multiple D0-brane (mD0) system described by recently proposed complete supersymmetric and $κ$-symmetric nonlinear action which includes an arbitrary positive definite function ${\cal M}({\cal H})$ of the relative motion Hamiltonian ${\cal H}$. First we show how the action with a particular nonlinear ${\cal M}({\cal H})$ can be obtained from the action for 11D multiple M-wave (multiple M0-brane or mM0) system. Then we obtain the complete set of equations of motion of mD0 system with arbitrary positive definite ${\cal M}({\cal H})$, perform a convenient gauge fixing, solve the center of energy equations and establish an interesting correspondence between the relative motion mD0 equations and the equations of maximal supersymmetric SU(N) Yang-Mills theory (SYM). We show that this correspondence does not imply a gauge equivalence but establishes a relation between solutions of the system. In particular, it implies that all the supersymmetric solutions of mD0 equations in its relative motion part coincide with supersymmetric solutions of the SYM equations.

Universality of the topological susceptibility in the SU(3) gauge theory

description: The definition and computation of the topological susceptibility in non-abelian gauge theories is complicated by the presence of non-integrable short-distance singularities. Recently, alternative representations of the susceptibility were discovered, which are singularity-free and do not require renormalization. Such an expression is here studied quantitatively, using the lattice formulation of the SU(3) gauge theory and numerical simulations. The results confirm the expected scaling of the susceptibility with respect to the lattice spacing and they also agree, within errors, with computations of the susceptibility based on the use of a chiral lattice Dirac operator.

Three-loop QCD matching of the flavor-changing scalar current involving the heavy charm and bottom quark

description: We compute the matching coefficient between the quantum chromodynamics (QCD) and the non-relativistic QCD ( NRQCD) for the flavor-changing scalar current involving the heavy charm and bottom quark, up to the three-loop order within the NRQCD factorization. For the first time, we obtain the analytical expressions for the three-loop renormalization constant $\tilde{Z}_s(x,R_f)$ and the corresponding anomalous dimension $\tildeγ_s(x,R_f)$ for the NRQCD scalar current with the two heavy bottom and charm quark. We present the precise numerical results for those relevant coefficients $(C_{FF}(x_0), \cdots, C_{FBB}(x_0))$ with an accuracy of about thirty digits. The three-loop QCD correction turns out to be significantly large. The obtained matching coefficient $C_s(μ_f,μ,m_b,m_c)$ is helpful to analyze the threshold behaviours when two different heavy quarks are close to each other and form the double heavy $B_c$ mesons.

description: Production and space-time evolution of heavy quarks in central and non-central heavy-ion collisions at RHIC and LHC are studied with the partonic transport model Boltzmann Approach of MultiParton Scatterings (BAMPS). In addition to the initially created heavy quarks in hard parton scatterings during nucleon-nucleon collisions, secondary heavy quark production in the quark-gluon plasma is investigated and the sensitivity on various parameters is estimated. In BAMPS heavy quarks scatter with particles of the medium via elastic collisions, whose cross section is calculated with the running coupling and a more precise implementation of Debye screening. In this framework, we compute the elliptic flow and nuclear modification factor of heavy quarks and compare it to the experimental data.

description: The problem of a bouncing ball on a non-planar surface is investigated. We discovered that surface undulation adds a horizontal component to the impact force, which acquires a random character. Some aspects of Brownian motion are found in the horizontal distribution of the particle. On the x-axis, normal and super diffusion are observed. For the probability density's functional form, a scaling hypothesis is presented.

description: The rise in data has led to the need for dimension reduction techniques, especially in the area of non-scalar variables, including time series, natural language processing, and computer vision. In this paper, we specifically investigate dimension reduction for time series through functional data analysis. Current methods for dimension reduction in functional data are functional principal component analysis and functional autoencoders, which are limited to linear mappings or scalar representations for the time series, which is inefficient. In real data applications, the nature of the data is much more complex. We propose a non-linear function-on-function approach, which consists of a functional encoder and a functional decoder, that uses continuous hidden layers consisting of continuous neurons to learn the structure inherent in functional data, which addresses the aforementioned concerns in the existing approaches. Our approach gives a low dimension latent representation by reducing the number of functional features as well as the timepoints at which the functions are observed. The effectiveness of the proposed model is demonstrated through multiple simulations and real data examples.

description: The  objective  of  this  study  looks  at  the  effectiveness  of  land  certification  on  sustainable
investments on land management in Doyogena wereda. It also looks the status of securing
land  rights  made  by  landholders  after  land  certification  program  and  extent  and
composition  of  disputes  over  land.  Primary  data  were  collected  through  survey
questionnaire,  group  discussion,  key  informant  interview  and  field  observation,  while
secondary  data  were  collected  from  governmental  organizations  carried  out  in  three
administrative  kebeles  from  the  total  fourteen  kebeles.  Sample  kebeles  were  selected  by
using simple random (lottery) sampling technique and 99 households were studied. The data
were analyzed by using qualitative techniques (verbal description),  statistical  analyses and
correlation analysis. As the results, tenure security was low during the past regimes because
of  frequent  land  redistribution  and  this  contributes  a  lot  towards  natural  resource  (land)
degradation in the wereda. Most of the existing rural economic and social situations of the
wereda can be traced back as manifestations of tenure insecurity. However, in response to
the  insecurity  problem  the  current  government  has  been  taken  measures  of  rural  land
certification  to  increase  tenure  security  by  granting  holding  certificate  as  legal  evidence.
Land certification has positive and significant effect in securing land rights of holders in
general  and  the  incentive  to  improve  investments  on  land  management  and  soil  f ertility
management  in  particular.  In  addition,  land  related  disputes  are  decreased  and  the
vulnerable group of the society especially women land rights are protected as a result of
holding  certificate.  Moreover,  there  was  low  productivity  of  farm  because  of  increasing
price of inputs such as  fertilizer and low awareness for certificate as  collateral  /guarantee/
to the financial institute and can get credits to buy farm inputs. In general, the findings of
the  study  demonstrate  that  the  feeling  of  land  rights  security  is  increasing  through  time,
while  land  certification  carried  out  to  increase  tenure  security  has  been  achieving  its
intended  objectives  and  is  sustainably  effective  in  improving  investments  on  land
management of landholders in the study wereda.
