description: The  focus  of  this  study  was  to  assess  challenges  and  opportunities  for  rural  poverty
reduction  in  Damot  Woyde  Woreda,  Wolaitta  zone,  Southern  Ethiopia.  Data  were
collected using questionnaire, FGD, interview and document analysis and also from rural
farmers  at household level, DAs, kebele administrators, key informant rural farmers and
heads/  representatives  of  Work  Process  of  Poverty  Reduction  oriented  sectors.119
Sample  households  were  selected  using  simple  random  sampling.  Data  gathered  using
questionnaire were analyzed using the SPSS where descriptive statistics were used for the
purpose.  As  to  the  study  findings,  poverty  is  currently  the  phenomenon  of  the  rural
population.  Its  level  and  depth  (poverty)  in  the  rural  areas  was  manifested  through
deprivation  of  consumption,  food  insecurity  and  reliance  on  PSNP  and  temporal
emergency  food  aid  support.  Different  policies,  strategies  and  practices  were
implemented in the rural areas but lacked effectiveness in lifting out the majority of rural
farmers from the  type of poverty they have faced. Result of the study indicated that rural
farmers faced strong challenges from climate change  (prolonged temperature and rainfall un certainty) and unexpected diseases of staple food crops such as maize (attacked by
maize  virus)  and  haricot  bean.  The  research  findings  also  revealed  that,  though  there
were  challenges  that  faced  the  rural  farmers  in  poverty  reduction,  there  are  also
untapped opportunities  (options and potentials)  in  the rural areas and the woreda that
contribute for poverty reduction and economic growth. Finally, the writer of this research
recommends  that  the  woreda  government,  non-governmental  organizations  and
responsible  government  sectors  should  address  challenges  and  efficient  and  effective
utilization of untapped opportunities. In addition, further researches should be conducted
in the same thematic areas
Analogy between streamers in sinking spheroids, gyrotactic plumes and chemotactic collapse

description: In a dilute suspension where sinking spheroids or motile gyrotactic microorganisms are modelled as orientable and negatively buoyant particles, we have found analytical solutions to their steady distributions under any arbitrary continuous vertical shear flow. The two-way coupling between their distribution and the vertical flow is nonlinear, enabling the uniform base state to bifurcate into a structure reminiscent of the streamers in settling spheroid suspensions and gyrotactic plumes. This bifurcation depends on a single parameter that is proportional to the average number of particles on a horizontal cross section. In a three-dimensional axisymmetric system, the plume structure blows up when the parameter is above a threshold. We discuss how this singularity is analogous to the chemotactic collapse of a Keller-Segel model, and the significance this analogy entails.

description: The structure of nematic liquid crystals formed by bent-core mesogens (BCMs) is studied in the context of Monte Carlo simulations of a simple molecular model that captures the symmetry, shape and flexibility of achiral BCMs. The results indicate the formation of (i) clusters exhibiting local smectic order, orthogonal or tilted, with strong in-layer polar correlations and anti-ferroelectric juxtaposition of successive layers and (ii) large homochiral domains through the helical arrangement of the tilted smectic clusters, whilst the orthogonal clusters produce achiral (untwisted) nematic states.

description: Spiral spin liquids are an exotic class of correlated paramagnets with an enigmatic magnetic ground state composed of a degenerate manifold of fluctuating spin spirals. Experimental realisations of the spiral spin liquid are scarce, mainly due to the prominence of structural distortions in candidate materials that can trigger order-by-disorder transitions to more conventionally ordered magnetic ground states. Expanding the pool of candidate materials that may host a spiral spin liquid is therefore crucial to realising this novel magnetic ground state and understanding its robustness against perturbations that arise in real materials. Here, we show that the material LiYbO$_2$ is the first experimental realisation of a spiral spin liquid predicted to emerge from the $J_1$-$J_2$ Heisenberg model on an elongated diamond lattice. Through a complementary combination of high-resolution and diffuse neutron magnetic scattering studies on a polycrystalline sample, we demonstrate that LiYbO$_2$ fulfils the requirements for the experimental realisation of the spiral spin liquid and reconstruct single-crystal diffuse neutron magnetic scattering maps that reveal continuous spiral spin contours -- a characteristic experimental hallmark of this exotic magnetic phase.

description: We study the bound of the noncommutativity parameter in the noncommutative Schwarzschild black hole which is a solution of the noncommutative ISO(3,1) Poincare gauge group. The statistical entropy satisfying the area law in the brick wall method yields a cutoff relation which depends on the noncommutativity parameter. Requiring both the cutoff parameter and the noncommutativity parameter to be real, the noncommutativity parameter can be shown to be bounded as $Θ> 8.4\ times 10^{-2}l_{p}$.

description: In East and Southeast Asia, a large proportion of the burgeoning, ageing population will live in high-rise, high-density residential environments. This research aimed to facilitate the retrofitting of these environments for the wellbeing of community-dwelling older adults. A transdisciplinary framework identified mental health as the main aspect of health affected by neighbourhood health processes. Correlations were found between older people’s neighbourhood experiences and positive mental health, which may be attributed to processes of embeddedness-interpersonal skills and communal affordance-emotional support. Moderating effect of neighbourhood-level geriatric depression was found, suggesting contextual preconditions to the neighbourhood health processes. Local incidents and local actors played a part in shaping the mental health atmosphere of high-rise, high-density neighbourhoods. These necessitated an urban community gerontology that finds its basis in the mental health atmosphere theory. Its implications on urban design and community planning practices were discussed in the context of Singapore’s public housing neighbourhoods.

description: Ethiopia  is  one  of  the  most  severely  affected  country  in  the  Eastern  Africa  particularly  in
rangeland degradation. The main objective of this study was to assess the impact of rangeland
degradation on the livelihood of semi-pastoral community of Malle Woreda, South Ethiopia. A
multi-stage random sampling technique was used. Data was collected from two kebeles, namely
Goloberendo and Kenbabobo. The main source of data for the study were 169 households, 20
FGD  participants and  10 interviewers.  The  instruments  used  for  data  collection  were
questionnaires,  interview,  focus  group  discussions  and GIS  and  remote sensing. The  data
obtained from questionnaires were analyzed using descriptive statistics such as mean, standard
deviation,  percentage,  frequency  and  inferential  statistics,  like independent  t-test  and chisquare test  were  employed  with  the  help  of  SPSS version 20.  Similarly,  multiple  linear
regression  model and  satellite image was used through  STATA  version  13  and  GIS and RS,
respectively. In  the  current  study, finding from satellite  image indicated  that, rangeland is
highly  degraded. The  result  showed  that  the area before  three  decades  were under a  good
rangeland  resources  are  changed  in  to  new  condition  of  degradation. Livestock population,
lack  of  diversified  income, human  population growth,  encroachment of  shrub, overgrazing,
traditional  herding,  variability  of  rainfall  and temperature and expansion  of farm land were
found statistically  significant  causes  of  rangeland  degradation. Besides, the  multiple linear
regression model analysis showed that,  impact  of  rangeland  degradation  on semi-pastoral
livelihood  determined  by age  of  households head,  family  size, access  to market, access  to
pasture,  drought,  households  head  education,  livestock  holding  size,  households  annual
income,  veterinary  service  and households mobility. On  the  other  hand,  the semi-pastoral
households develop strategies, like mobility, selling of livestock, distribution of their livestock
to other closet households resides in different kebele, used as rangeland trees as feed resources
for  their  livestock,  communal  and  private  water  harvest  and  private  pasture  for  their milky
livestock during shortage of forage and water. In addition, non-pastoral and off-farm activities
were  statistically significant  relationship with effects  of  rangeland  degradation. In  order  to
alleviate these problems the government, other concerned bodies, NGOs and community should
work jointly  to rangeland development  and  management  with  the diversification  of semipastoral livelihood of the study area.

description: Solid  waste  which  is  a  consequence  of  day-to-day  activity  of  human  kind, needs  to  be
managed  properly.  Hossana,  like  other  towns  in  Ethiopia,  faces  serious  problems
associated with solid waste management and disposal practices. The increasing amount
of solid waste production was exacerbated the impact of related problems. This study was
conducted with the objectives of to explore the challenges and practices of solid waste
management and  disposal  activity  in  Hossana  town.  Different  sampling  methods  were
employed  to select  the  study  units  like  stratified  sampling,  techniques and  purposive
sampling. Even though most of the collected data from the interviewed respondents were
qualitative in nature, it was also supported by quantitative information collected through
survey  and  secondary  sources. The  analysis  of  this  paper  was  carried  out  using
bothqualitative  and  quantitative  techniques.  Lack  of  public  awareness,  low
implementation of rules and regulation, lack of institutional coordination and absence of
financing,  poor  condition  of  solid  waste  disposal  practices,  lack  of  private  sector
participation  and low  community  involvement  was  the  challenges  of solid  waste
managementand disposal practices in Hossana town. Therefore, the best ways that used
to tackle the above problems are: implementation of sustainable solid waste management
practices  through  awarenesscreation  and  training,  improvement  of  sanitation,
beautification and parking sector institutional structure and budget allocation, implement
of  rules  and  regulation  and  involvement  of  community  in solid  waste  management
practices  all  stakeholders. Solid  waste  management and  disposal  practice  strategies
developed for Hossana town have a number of importance for minimizing the problems
that  faced  the  current  municipality’s  proper solid  waste  management  and  disposal
practices.  Finally,  the  study  forwarded  some  important  recommendations  towards
implementing the developed strategies to mitigate the existing solid waste management
problems.

description: In previous work, Bender and Komijani (2015 \textit{J. Phys. A: Math. Theor.} 48, 475202) studied the first Painlevé (PI) equation and showed that the sequence of initial conditions giving rise to separatrix solutions could be asymptotically determined using a $\mathcal{PT}$-symmetric Hamiltonian. In the present work, we consider the initial value problem of the PI equation in a more general setting. We show that the initial conditions $(y(0),y'(0))=(a,b)$ located on a sequence of curves $Γ_n$, $n=1,2,\dots$, will give rise to separatrix solutions. These curves separate the singular and the oscillating solutions of PI. The limiting form equation $b^2/4 - a^3=f_n \sim A n^{6/5}$ for the curves $Γ_{n}$ as $n\to\infty$ is derived, where $A$ is a positive constant. The discrete set $\{f_n\}$ could be regarded as the nonlinear eigenvalues. Our analytical asymptotic formula of $Γ_n$ matches the numerical results remarkably well, even for small $n$. The main tool is the method of uniform asymptotics introduced by Bassom et al. (1998 \textit{Arch. Rational Mech. Anal.} {143}, 241--271) in the studies of the second Painlevé equation.

description: We explore the electromagnetic gauge invariance of the hadron tensor of the Drell-Yan process with one transversely polarized hadron. The special role is played by the contour gauge for gluon fields. The prescription for the gluonic pole in the twist 3 correlator is related to causality property and compared with the prescriptions for exclusive hard processes. As a result we get the extra contributions, which naively do not have an imaginary phase. The single spin asymmetry for the Drell-Yan process is accordingly enhanced by the factor of two.

description: The effective potential obtained by loop expansion is usually not real in the range of field values explored by its minima during a phase transition. We apply the optimized perturbation theory in a fixed gauge to singlet scalar extensions of the Standard Model in order to calculate a one-loop effective potential that is real by construction. We test this computational scheme by comparing such a potential obtained in Landau gauge to that derived based on the Higgs pole mass. We carry out the latter construction by imposing physical renormalization conditions, which yields a potential without residual regularization scale dependence. We use our effective potential to study the parameter dependence of the critical temperatures in a two-step phase transition of the form $(0,0)\to (0,w')\to (v,w)$ that occurs for decreasing temperature in scalar extensions of the SM with two vacuum expectation values $v$ and $w$.

description: Als eine Form der Kommunikation ist das Dolmetschen unweigerlich an die Kommunikationsformen und Kommunikationsmedien der miteinander kommunizierenden Personen gebunden. Entsprechend kann davon ausgegangen werden, dass sich mit den Realisierungsbedingungen auch die Anforderungen und Strategien ändern. Angetrieben durch die kontinuierliche Entwicklung, aber auch durch die steigende Verfügbarkeit von Informations- und Kommunikationstechnologien, ist auch für das Dolmetschen mit erheblichen Veränderungen zu rechnen. Es ist demnach anzunehmen, dass sich die Digitalisierung und die damit einhergehenden Digitalisierungsprozesse auf den beruflichen Alltag der Dolmetscherinnen und Dolmetscher auswirken. Aufgrund der COVID-19-Pandemie und dem damit zusammenhängenden verstärkten Einsatz von Technologie ist davon auszugehen, dass der digitale Wandel in dieser Berufsgruppe einschneidende Veränderungen herbeigeführt hat. Vor diesem Hintergrund war es das Ziel dieser Umfrage, zu ermitteln, welche Entwicklungen die Digitalisierung in der Berufsgruppe der Dolmetscherinnen und Dolmetscher verzeichnete und welche Auswirkungen sie auf den beruflichen Alltag hat. Die Zielgruppe der Befragung waren Dolmetscherinnen und Dolmetscher im DACH-Raum, die per Video- und/oder Audio dolmetschen. Folgende vier Schwerpunkte wurden festgelegt: Video- und Audiodolmetschen, Remote-Arbeitsplatz, digitale Kompetenzen und Weiterbildung.

description: The purpose of this study was to assess/investigate Women’s Self-Help Groups in Poverty
Reduction at Mehal- Ketema Sub City in Hawassa. Descriptive survey design was employed.
Quantitative data were collected, through questionnaires, from 162 women’s self-help group
respondents. The researcher has employed simple random sampling technique to select her
respondents. Semi-structured interviews were also held with six experts from Mehal Ketema sub
city Women and Children Affair office (especially Women Capacity Building Core Process),
OMF office, Finance Economic Developmental Department, Hawassa City Administration
Women Capacity Empowerment Core Work Process, and NGOs, in order to get additional
information about the groups contributions in poverty reduction was  interviewed.  In the study,
one focus group discussion was held. The focus group has consisted purposively selected seven
Women's Self-Help Group leaders from the groups to get deeper understanding on its role in
poverty reduction among the group members. Using SPSS version 20, quantitative data were
analyzed using descriptive statistics such as percentage, mean, standard deviation, and
inferential statistics such as chi-square test. Finding of the study revealed that on the case of
Women's Self-Help Group Interventions on Poverty Reduction, some SHG members resign from
membership with trivial cases. The data analysed revealed that even if some women SHG
members have generated income that can cover their monthly expenditure, start to save money
and able to change their household, still it is exhibited that there are some women participating
in their SHG are not able to do so. As the researcher observed, in Poverty alleviation activities
the role-played by the selected women’s SHGs in terms of poverty reduction in the study area
generally revealed that it contributed towards reducing the pressure of poverty of the
beneficiaries. Therefore, in order to be effective in achieving the goal, all the development
actors and the beneficiaries should focus on long term and value- added projects than
immediate benefit that satisfy their daily needs.

description: The eighth part of the OGLE-III Catalog of Variable Stars (OIII-CVS) contains type II Cepheids in the Small Magellanic Cloud (SMC). The sample consists of 43 objects, including 17 BL Her, 17 W Vir and 9 RV Tau stars (first examples ever found in the SMC). Seven stars have been classified as peculiar W Vir stars - a recently identified subclass of type II Cepheids. These stars have distinctive light curves, are brighter and bluer than the ordinary W Vir variables. We confirm that a large fraction of the peculiar W Vir stars are members of binary systems. Three type II Cepheids exhibit eclipsing variations superimposed on the pulsation light curves, and three other objects show long-period ellipsoidal variability. All stars with the indication of binarity display secondary periods which may be interpreted as amplitude and/or phase modulations of the pulsation light curves with periods equal to the orbital periods or half the orbital periods. We do not have any model for these modulations, however this phenomenon rules out a possibility of the optical blends of a pulsating star and a binary system. For each object the multi-epoch V- and I-band photometry collected over 8 or 13 years of observations and finding charts are available to the astronomical community from the OGLE Internet archive.

description: A distinguishing feature of ultracold collisions of bosonic lithium atoms is the presence of two near-degenerate two-body continua. The influence of such a near-degeneracy on the few-body physics in the vicinity of a narrow Feshbach resonance is investigated within the framework of a minimal model with two atomic continua and one closed molecular channel. The model allows analysis of the spin composition of loosely bound dimers and trimers. In the two-body sector the well-established coupled-channels calculations phenomenology of lithium is qualitatively reproduced, and its particularities are emphasized and clarified. In the three-body sector we find that the Efimov trimer energy levels follow a different functional form as compared to a single continuum scenario while the thresholds remain untouched. This three-channel model with two atomic continua complements our earlier developed three-channel model with two molecular channels [Y. Yudkin and L. Khaykovich, Phys. Rev. A 103, 063303 (2021)] and suggests that the experimentally observed exotic behavior of the first excited Efimov energy level [Y. Yudkin, R. Elbaz and L. Khaykovich, arXiv:2004.02723] is most probably caused by the short-range details of the interaction potential.

description: The 2-d spin 1/2 Heisenberg antiferromagnet with exchange coupling $J$ is investigated on a periodic square lattice of spacing $a$ at very small temperatures using the loop-cluster algorithm. Monte Carlo data for the staggered and uniform susceptibilities are compared with analytic results obtained in the systematic low-energy effective field theory for the staggered magnetization order parameter. The low-energy parameters of the effective theory, i.e.\ the staggered magnetization density ${\cal M}_s = 0.30743(1)/a^2$, the spin stiffness $ρ_s = 0.18081(11) J$, and the spin wave velocity $c = 1.6586(3) J a$ are determined with very high precision. Our study may serve as a test case for the comparison of lattice QCD Monte Carlo data with analytic predictions of the chiral effective theory for pions and nucleons, which is vital for the quantitative understanding of the strong interaction at low energies.

The role of granzyme B in the degradation of periodontal connective tissues
Creators: name: Ahmadi, Amir Reza
Publisher: name: University of British Columbia

description: Objective: Periodontitis (gum disease) is characterized by the degradation of tooth- supporting connective tissues, largely due to matrix metalloproteinase (MMP) release by fibroblasts residing in the gingival (gum) tissue. Granzyme B (GzmB) is a serine protease whose role in periodontitis is undefined. Here we studied the role of GzmB in the context of periodontitis. Methods: Gingival fibroblasts were cultured in the presence or absence of recombinant GzmB. Culture supernatants were analyzed by enzyme-linked immunosorbent assay (ELISA) to quantify GzmB-induced release of collagenase (MMP-1). MMP-1 expression was quantified by qPCR. In some experiments, cells were pre-treated with PD98059 to block MEK/ERK signaling. The protease-activated receptor-1 (PAR-1) was blocked with ATAP-2 neutralizing antibody prior to GzmB stimulation. Human samples of gingival crevicular fluid (GCF), an inflammatory transudate released at the dento-gingival (tooth- gum) interface, were obtained from teeth with periodontal disease and healthy control teeth. GzmB was quantified in the GCF ([GzmB]GCF) by ELISA. Results: Recombinant GzmB induced a ~4-5-fold increase in MMP-1 secretion by cultured fibroblasts. GzmB induced phosphorylation of Erk1/2 which was abrogated by PD98059. GzmB-induced upregulation of MMP-1 gene expression/secretion were also reduced by PD98059. Blockade of PAR-1 function by ATAP-2 abrogated the GzmB- induced increase in MMP-1 secretion by GF. The [GzmB]GCF was ~4-5 fold higher at sites of periodontal disease (gingivitis/periodontitis) compared to healthy control sites, suggesting an association between GzmB and matrix degradation. Conclusions: These data point to a novel GzmB-driven signaling pathway in fibroblasts in which MMP-1 expression and secretion are upregulated in a PAR1- and Erk1/2- dependent manner.

description: Land degradation is one of the major challenges in agricultural production in many parts of
the  world,  especially  in  developing  nations  like  Ethiopia.  Even  though  a  number  of  soil  and
water conservation methods were introduced to combat this problem adoption of conservation
practices  remains  below  expectations.  This  study  was  conducted  on  the  practices  and
perception  of  farmers  on  soil erosion  and  soil conservation  practices  in  Gumer  Woreda;
Gurage  zone,  SNNPR,  Ethiopia.  It  aimed  to  assess  the  soil erosion and  soilconservation
practices, in Gumer Woreda area. Systematic random sampling technique was used and selects
167  sample  households  beside  three  for  key  informant  and  nine  household  for  focus  group
discussion  and  the  total  sample  size  became  179. Data  analysis  was  carried  out  by  using
quantitative analysis and qualitative description. The finding of the study indicate that decrease
in productivity of farmland, increase in size of population, lack of full cooperation between the
farmers and agricultural expert , less awareness of the farmers in soil and water conservation
the  adoption  of  improved  farmland  management,  less  access  to  agricultural expert  services,
less number of the development agents, inadequate attention given from Woreda’s Agricultural
and Rural  Development  office  are  the  major  challenges  encountering the  implementation  of
farmland management practices. Awareness creation and continuous training for the farmers
helps the practicing of farmland management in the study area, challenge of soil conservation
practice, the method used for conservation of soil, lack of full cooperation between the farmers
and,  less  awareness  of  the  farmers  in  soil  conservation  practice,  less  number  of  the
development agents.

description: The present study assessed the Status, Challenges and prospects of tourism industry in Konso
Woreda, Segen Zone, Southern Ethiopia. The main objective of the study was to assess the
challenges of tourism industry and its prospects in Konso Woreda. To achieve the objective,
the researcher used a survey design. The primary data were collected through questionnaire,
semi-structured interview, and observation from the field. To support the primary data,
secondary data also collected from different documents and studies and all were analyzed
qualitatively. From the findings of the study, Konso has  various  natural and cultural
potentialities required for tourism development. These are  Moras,  Wakaas  and  good
terraced areas. Likewise, Walled villages or towns and New York natural  land feature and
different cultural ceremonies  are the  potentials of tourism. However, the industry has not
grown significantly. As the finding indicates 90.6% of the respondents didn‟t have any
contact with tourism industry. Unfortunately only 9.4% of the respondents have a direct
interaction with the industry. On the other hand, their income is less than 30 ETB per day in
average. This articulates the economic significance of the community is low compared to the
tourism wealth of the Woreda. As the finding  also  indicates, tourism industry in Konso
Woreda has  several  challenges.  The foremost problems of tourism identified by this study
were underdeveloped infrastructure and facilities, safety and security, underdeveloped ICT,
lack of implementing  national  policies and lack of professionalism.  Moreover,  lack of
marketing and promotion,  below standard accommodations  and lack of coordination  also
affect the industry negatively. The prospects of tourism in the study area includes availability
of different natural and cultural tourist destinations, economical tourist expenses, good
cultural ceremonies and supportive  national policies. Similarly, welcoming  people, under-
construction of new hotels and lodges, registration of the landscape in UNESCO also
contributes a pronounced role for the future development of the industry. Finally this paper
recommended that participation and coordination of all concerned bodies and stakeholders
(governments and community) is very imperative in solving the challenges and to develop the
industry in the study area.
Rotation in vacuum and scalar background: are there alternatives to Newman-Janis algorithm?

description: The Newman-Janis algorithm is the standard approach to rotation in general relativity which, in vacuum, builds the Kerr metric from the Schwarzschild spacetime. Recently, we have shown that the same algorithm applied to the Papapetrou antiscalar spacetime produces a rotational metric devoid of horizons and ergospheres. Though exact in the scalar sector, this metric, however, satisfies the Einstein equations only asymptotically. We argue that this discrepancy between geometric and matter parts (essential only inside gravitational radius scale) is caused by the violation of the Hawking-Ellis energy conditions for the scalar energy-momentum tensor. The axial potential functions entering the metrics appear to be of the same form both in vacuum and scalar background, and they also coincide with the linearized Yang-Mills field, which might hint at their common non-gravitational origin. As an alternative to the Kerr-type spacetimes produced by Newman-Janis algorithm we suggest the exact solution obtained by local rotational coordinate transformation from the Schwarzschild spacetime. Then, comparison with the Kerr-type metrics shows that the Lense-Thirring phenomenon might be treated as a coordinate effect, similar to the Coriolis force.

description: Education is the process  in which Knowledge and skill transferred to other people through
discussion, teaching and research. It plays a significant role for the civilization,
modernization and  development of any country.  Ethiopia has a long and rich history of
educational  traditions such as Indigenous, Religious and Modern education in Ethiopia. The
study was confined to Sendafa Preparatory School in Special Zone of Oromia state of
Ethiopia. It employed mixed-method approaches and descriptive survey design. Among 183
social science learners 126 learners were sampled through lottery sampling technique. But
all Geography teachers and departmental heads were taken as the main participants through
purposive sampling techniques. Questionnaire, structured interviews, observation and
documents were the main data collection instruments for the study. Data that were collected
through close-ended questionnaires were edited, coded, classified, tabulated and organized
in the form of tables have been analyzed through frequency, percentage and mean via SPSS
software. However, data that were collected through interviews, observation and open-ended
questionnaire were analyzed inductively using narrations and descriptions through words,
phrases and statements, whereas the data collected from documents were organized in the
form of tables and analyzed via percentage.  Based on the analyzed data, findings were
depicted. The finding of the study revealed that majority  of teachers’ frequently practice
teacher-centered method teaching, teachers’ failure to utilize teaching materials, shortage of
time, poor teacher-student relationship, teachers failed to measure learners’ academic
progress through continuous assessment techniques, absence of plasma TV transmission and
dearth of instructional resources  such as reference books, pedagogical centre, scarcity of
budget were considerable hindrances on the implementation of Geography syllabus through
the participatory approaches  of teaching methods. Based on the findings of the study,
recommendations were made to the concerned bodies to alleviate problem of the quality of
teaching-learning process in Geography participatory teaching approach and utilization of
resource upgrade the quality of education and increase learners’ achievement.

description: We discuss the resummation of the large logarithmic terms appearing in the heavy quark effects on parton distribution functions inside the virtual photon. We incorporate heavy quark mass effects by changing the initial condition of the leading-order DGLAP evolution equation. In a certain kinematical limit, we recover the logarithmic terms of the next-to-leading order heavy quark effects obtained in the previous work. This method enables us to resum the large logarithmic terms due to heavy quark mass effects on the parton distributions in the virtual photon. We numerically calculate parton distributions using the formulae derived in this work, and discuss the property of the resummed heavy quark effects.

description: We demonstrate a simple and cost-efficient scanning confocal microscope setup for use in advanced instructional physics laboratories. The setup is constructed from readily available commercial products, and the implementation of a 3D-printed flexure stage allows for further cost reduction and pedagogical opportunity. Experiments exploring the thickness of a microscope slide and the surface of solid objects with height variation are presented as foundational components of undergraduate laboratory projects, and demonstrate the capabilities of a confocal microscope. This system allows observation of key components of a confocal microscope, including depth perception and data acquisition via transverse scanning, making it an excellent pedagogical resource.

description: Esta ponencia nace de la revision de un articulo anterior sobre la aplicacion de la hermeneutica a la etnografia. Siendo asi, que se proponga una lectura de la cultura como un texto, en la cual, es la labor del etnografo realizar la develacion de su contexto.. De ahi que cuando Hermes Trismegisto acompana al etnografo, le permite a este que cuando represente una cultura, un acontecimiento, escena o un sujeto, no establezca una tesis, sino que incita al lector a formularla: no impone, sino que propone, y por lo tanto deja libre a su lector y al mismo tiempo lo invita a ser mas activo. Alcanzando asi en la compania de este ser alado, mediante la utilizacion evocadora de las palabras, que el texto producido provoque un temblor en el sentido, poniendo en marcha el dispositivo de interpretacion simbolica del etnografo y despertando asimismo, sus capacidades de asociacion.
