RESEARCH  ON  THE  EFFECT  OF  teacher and  PEER  FEEDBACK  ON  STUDENTS’ PARAGRAPH WRITING PERFORMANCE AND ATTITUDES AT ARBAMINCH COLLEGE OF  TEACHERS’ EDUCATION: DAWROGNA MAJORING STUDENTS ON FOCUS.  BY

description: This  study  aimed  to  investigate  the  outcomes  of  teacher  and  peer  feedback  on  EFL  students’
writing  performances.  Moreover,  the  study  was  intended  to  assess  attitudes  of  EFL  students
towards the provision of teacher and peer feedback in paragraph writing. Data collection  was
carried out through two instruments: paragraph writing tests and  questionnaire. The reliability
and  validity  of  the  instruments  were  verified  by  using  Cronbach’s  Alpha.  The  study  sample
consisted of 30 EFL minoring prospective primary teachers at Arba Minch College of Teachers’
Education. The subjects of the study were equally divided into two groups: control (n=15) and
experimental  (n=  15).  Both  groups  were  similar  in  terms  of  academic  level,  mother  tongue
background  and  their  target  language  learning  experiences.  The  experimental  group
participants were introduced with peer feedback in paragraph  writing sessions while the control
group participants were taught by the teacher provided with teacher feedback. In order to find
out the effect of peer on EFL students’ writing performance experimental research design  was
employed. To analyze the data quantitative method was used. The data gathered through writing
paragraph and the questionnaire  was analyzed quantitatively. Both the data gathered through
writing paragraph and questionnaires (writing attitude inventory, see appendix) were analyzed
using independent sample t-test. The results of data collection showed the provision of teacher
and peer feedback did not play any significant role in improving the students’ paragraph writing
at  0.05  (df=28)  critical  t-value  2.048  level  of  significance.  The  analysis  of  each  feature  of
writing showed that there  was no significant difference between two groups; however students
were able to correct low level concern (non-impeding errors). From this we assert that students
were required to be trained to be aware of high order concern (meaning impeding errors). From
the analysis of questionnaire finding reveals that the experimental group showed high variation
compared  with  that  of  control  group  in  their  attitudes  toward  peer  feedback.  Finally
recommendations and discussion were made based on the results and finding of the study

description: After reviewing the evidence that QCD matter at ultrarelativistic energies behaves as a very good fluid, we describe the connection of QCD fluidity to heavy quark observables. We review the way in which heavy quark spectra can place tighter limits on the viscosity of QCD matter. Finally, we show that correlations between flow observables and the event-by-event charm quark abundance ("flavoring") can shed light on the system's equation of state.

Mortality, Time, and the Lessons of Silence: A Hermeneutical Analysis of Give and Take
Creators: name: Keane, Dr. Niall
Publisher: name: Journal of Applied Hermeneutics
Year: 2021

description: The following will provide a hermeneutical examination of two experiences of time: time as taking-away and time as giving. It will attempt to address the interrelated issues of death, time, and the time of silence in order to see whether time should be viewed as an inevitable force that destroys everything in front of it, or whether another concept of time should be considered, one which comes from the other as the gift of time. It will be argued that the gift of time is only fully audible in the time of silence and that gratitude is most well-attuned response to such a time and to the time that precedes and exceeds us.

description: Recurrently coupled oscillators that are sufficiently heterogeneous and/or randomly coupled can show an asynchronous activity in which there are no significant correlations among the units of the network. The asynchronous state can nevertheless exhibit a rich temporal correlation statistics, that is generally difficult to capture theoretically. For randomly coupled rotator networks, it is possible to derive differential equations that determine the autocorrelation functions of the network noise and of the single elements in the network. So far, the theory has been restricted to statistically homogeneous networks, making it difficult to apply this framework to real-world networks, which are structured with respect to the properties of the single units and their connectivity. A particularly striking case are neural networks for which one has to distinguish between excitatory and inhibitory neurons, which drive their target neurons towards or away from firing threshold. To take into account network structures like that, here we extend the theory for rotator networks to the case of multiple populations. Specifically, we derive a system of differential equations that govern the self-consistent autocorrelation functions of the network fluctuations in the respective populations. We then apply this general theory to the special but important case of recurrent networks of excitatory and inhibitory units in the balanced case and compare our theory to numerical simulations. We inspect the effect of the network structure on the noise statistics by comparing our results to the case of an equivalent homogeneous network devoid of internal structure. Our results show that structured connectivity and heterogeneity of the oscillator type can both enhance or reduce the overall strength of the generated network noise and shape its temporal correlations.

Improvisation as Original Ethics: Exploring the Ethical in Heidegger and Gadamer from a Musical Perspective
Creators: name: McAuliffe, Sam
Publisher: name: Journal of Applied Hermeneutics
Year: 2021

description: Martin Heidegger famously claimed that ethics needed to become “original” again, but offered no detailed insight into what an “original ethics” might be. Several commentators, however, find evidence of such an original ethics in the philosophical hermeneutics of Hans-Georg Gadamer. In this paper I argue that an original ethics, as alluded to by Heidegger and taken up by Gadamer, depends upon a certain improvisational comportment, such that acting ethically involves spontaneously attending and responding to that which one encounters in factical existence. To substantiate this claim, I draw upon improvised musical performance as an exemplar, highlighting how the responsiveness at issue in musical improvisation is equally present in an original ethics, which is itself demonstrative of a practical, performative, and spontaneous engagement with the world. This account not only elucidates the improvisational character of ethics, it equally illuminates the nature of the ethical at issue in improvised musical performance.

description: We explore the topological behavior of the binary Zintl phase of the alkaline earth metals based compounds Sr$_2$Pb and Sr$_2$Sn using both standard and hybrid density functional theory. It is found that Sr$_2$Pb lies on the verge of a topological instability which can be suitably tuned through the application of a small uniaxial expansion strain ($>$ 3%). The resulting non-trivial topologically insulating state display well-defined metallic states in the Sr$_{2}$Pb(010) surface, whose evolution is studied as a function of the film thickness.

AN ASSESSMENT OF THE IMPLEMENTATION OF  GROUP WORK IN EFL CLASSROOMS
Creators: name: KALEB TADEWOS
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: Group  work  is  one  of  effective  methods  to  motivate  students,  to  create  a  good  learning
environment  and  develop  a  key  critical-thinking,  communication  and  decision  making
skills.  It  should  be  implemented  carefully  in  order  to  make  teaching  learning  process
effective. The purpose of this study was assessing the implementation of group work during
reading comprehension in EFL classroom. This research was conducted in two secondary
schools  of  Wolaitta  zone,  Sodo  secondary  and  Tebela  Gen/  secondary  and  Preparatory
schools. From these two schools, 12 sample sections of grade 9 were used.   To achieve the
intended goal, this study followed descriptive study design. An assessment of group  work
implementation in classroom was done by using 32 structured classroom observations. Each
of  the  selected  classrooms  was  observed  twice.  In  order  to  consolidate  and  validate  data
gathered  through  classroom  observation,  teachers‟  and  students‟  questionnaire  were
employed.  The  collected  data  were  analyzed  and  discussed  using  descriptive  statistical
tools.  The result of the study revealed that the teachers were not fully committed to perform
their roles in the implementation of group work. The students were also not fully committed
to  participate  in  group  work. Their  involvement  in  group  work  discussion  was  very  low.
Therefore, recommendations were forwarded to teachers to make careful planning and play
their roles properly when they organize group work and  assign the students in group.

description: Most quantum point contacts (QPCs) fabricated in high-mobility 2D electron gases show a zero-bias conductance peak near pinchoff, but the origin of this peak remains a mystery. Previous experiments have primarily focused on the zero-bias peak at moderate conductance, in the range (1-2)e^2/h. Here, measurements are presented of zero-bias peaks that persist down to 10^{-4}e^2/h. Magnetic field and temperature dependencies of the zero-bias peak in the low-conductance limit are qualitatively different from the analogous phenomenology at higher conductance, with implications for existing theoretical models of transport in low-density QPCs.

description: The Horizon 2020 SHERPA (Sustainable Hub to Engage into Rural Policies with Actors) project has made a contribution on behalf of 20 different Multi-Actor Platforms (MAPs) to the preparation of a new long-term vision for rural areas initiated by the European Commission. The Hungarian MAP – one of the groups of science-society-policy actors – chose the Agricultural Knowledge and Innovation System (AKIS), more precisely digitalisation, as its flagship topic due to the fact that it is a horizontal issue and it is embedded even into the Common Agricultural Policy’s (CAP) strategic planning process. Thus, the development of AKIS requires close and intensive cooperation of policy makers, researchers and farmers or – in broader context – the society with various stakeholders. The aim of the Hungarian research team was to identify the current and likely trends for the Hungarian rural areas and to point out key challenges, opportunities, enablers and barriers in rural development in terms of digitalisation up to 2040. The methodology used was the Delphi technique. In the first phase, a review of key trends, main challenges and opportunities and a summary of existing foresight regarding digital agriculture was written. Then AKIS experts were asked to talk about their experiences and opinions in the framework of interviews, a focus group meeting and a survey. In the end, results of the survey were discussed in a consensus meeting. Among the results, it is worth mentioning that digitisation and digitalisation will fundamentally change how rural areas operate including economic, environmental and social dimensions. The main enablers of a promising future vision are capacity building for knowledge transfer, adaptation for job creation and offering better quality of life, stronger community building for collaborations, deeper government involvement, and last but not least, strengthening the local identity in rural areas. ocial responsibility and this makes a promising background for further research.

Dialogue in radical hospitality : creating meaning of democratic education through dialogic cooking
Creators: name: Roll, Ofira
Publisher: name: University of British Columbia
Year: 2019

description: This study explores the playful dialogical process of creating meaning while cooking collaboratively with the teaching staff in a democratic school in Vancouver, British Columbia. All Kindergarten to Grade-12 staff members in the school were invited to participate in this study. Of the 22 staff, 16 chose to participate in yearlong gatherings in which we cooked collaboratively while sharing, reflecting, questioning, and creating meaning with one another’s practices, beliefs, and narratives. Through this artistic socially engaged and participatory research, a new meaning of democratic education was created together and apart. These methodologies invited the staff to be equal participants in complicated conversations within and beyond the walls of the school, as mentors, members in the community, teachers, friends, parents, artists, and at times participant researchers. The four gatherings throughout the year were video and audio-recorded. They included complicated conversations while collaborative cooking took place. The entry and exit small group interviews were also audio-recorded. Those gatherings and interviews assisted participants in creating a new meaning of democratic education for them as collective and as relational individuals. This study situated complicated conversations and cooking collaboratively as an inquiry that focused on creating meaning in which dialogue could engage the community with topics they deemed important. Through cooking and feasting together, we held the intention of creating trusted space with a sense of nurturing and hospitality in which we encountered difficult knowledge together while creating meaning of democratic education. This study may contribute to a greater understanding of democratic education. It offers the understanding that a school community (a) can support an ongoing process of dialogic culture; (b) benefits from engaging in an artistic collaborative process while sharing nurturing spaces that holds feasts; and (c) is capable of making democratic practices for personal growth, compassion, sense of agency, and democratic structures within a community, available and tangible for Kindergarten to Grade-12 students, staff, and families at the individual and collective spheres on the local and global level.

description: The cross-correlation search has been previously applied to map the gravitational wave (GW) stochastic background in the sky and also to target GW from rotating neutron stars/pulsars. Here we investigate how the cross-correlation method can be used to target a small region in the sky spanning at most a few pixels, where a pixel in the sky is determined by the diffraction limit which depends on the (i) baseline joining a pair of detectors and (ii) detector bandwidth. Here as one of the promising targets, we consider the Virgo cluster - a "hot spot" spanning few pixels - which could contain, as estimates suggest $\sim 10^{11}$ neutron stars, of which a small fraction would continuously emit GW in the bandwidth of the detectors. For the detector baselines, we consider advanced detector pairs among LCGT, LIGO, Virgo, ET etc. Our results show that sufficient signal to noise can be accumulated with integration times of the order of a year. The results improve for the multibaseline search. This analysis could as well be applied to other likely hot spots in the sky and other possible pairs of detectors.

description: We study the impact of lattice data on the determination of the strangeness asymmetry distribution $s_-(x) \equiv s(x) - {\bar s}(x)$ in the general CTEQ-TEA global analysis of parton distribution functions (PDFs) of the proton. Firstly, we find that allowing a nonvanishing $s_-(x)$, at the initial $Q_0=1.3$~GeV scale, in a global PDF analysis leads to a CT18As fit with similar quality to CT18A. Secondly, including the lattice data in the CT18As\_Lat fit greatly reduces the $s_-$-PDF error band size in the large-$x$ region. To further reduce its error would require more precise lattice data, extended to smaller $x$ values. We take ATLAS 7 TeV $W$ and $Z$ production data, SIDIS di-muon production data, $F_3$ structure function data, E866 NuSea data, and E906 SeaQuest data as examples to illustrate the implication of CT18As and CT18As\_Lat fits. The parametrization dependence for PDF ratio $(s+\bar{s})/(\bar{u}+\bar{d})(x)$ is analyzed with CT18As2 and CT18As2\_Lat fits as results.

description: In a Schwarzschild-de Sitter space, we consider an equipotential surface which consists of two holographic screens. Adapting the Bousso-Hawking's reference point of vanishing force, we divide the space into two regions, which are from the reference point to each holographic screen. These two regions can be treated as independent thermodynamical systems, because the Bousso-Hawking reference point with zero temperature behaves like a thermally insulating wall. The entropy obtained in this way agrees with the conventional results; i) when the holographic screens lie at the black hole and cosmological horizons, ii) in the Nariai limit.

description: Gravitational waves emitted from the binary neutron star (BNS) systems can carry information about the dense matter phase in these compact stars. The crust-core interfacial mode is an oscillation mode in a neutron star and it depends mostly on the equation of the state of the matter in the crust-core transition region. This mode can be resonantly excited by the tidal field of an inspiraling-in BNS system, thereby affecting the emitted gravitational waves, and hence could be used to probe the equation of state in the crust-core transition region. In this work, we investigate in detail how the first-order phase transition inside the neutron star affects the properties of the crust-core interfacial mode, using a Newtonian fluid perturbation theory on a general relativistic background solution of the stellar structure. Two possible types of phase transitions are considered: (1) the phase transitions happen in the fluid core but near the crust-core interface, which results in density discontinuities; and (2) the strong interaction phase transitions in the dense core (as in the conventional hybrid star case). These phase transitions' impacts on interfacial mode properties are discussed. In particular, the former phase transition has a minor effect on the M-R relation and the adiabatic tidal deformability, but can significantly affect the interfacial mode frequency and thereby could be probed using gravitational waves. For the BNS systems, we discuss the possible observational signatures of these phase transitions in the gravitational waveforms and their detectability. Our work enriches the exploration of the physical properties of the crust-core interfacial mode and provides a promising method for probing the phase transition using the seismology of a compact star.

description: Modern astronomical observations give unprecedented access to the physical properties of nearby galaxies, including spatially resolved stellar populations. However, observations can only give a present-day view of the Universe, whereas cosmological simulations give access to the past record of the processes that galaxies have experienced in their evolution. To connect the events that happened in the past with galactic properties as seen today, simulations must be taken to a common ground before being compared to observations. We emulate data from the MaNGA survey, which is the largest integral field spectroscopic galaxy survey to date with its 10,000 nearby galaxies of all types. For this, we use the cosmological simulations TNG50 to generate MaNGIA (Mapping Nearby Galaxies with IllustrisTNG Astrophysics), a mock MaNGA sample of similar size that emulates observations of galaxies for stellar population analysis. We choose TNG galaxies to match the MaNGA sample selection to limit the impact of selection effects. We produce MaNGA-like datacubes from all simulated galaxies, and process these with the pyPipe3D analysis code. This allows us to extract spatially resolved stellar maps. This first paper presents the approach to generate the mock sample and provides an initial exploration of its properties. We show that the stellar populations and kinematics of the simulated MaNGIA galaxies are overall in good agreement with observations. Specific discrepancies, especially in the age and metallicity gradients in low- to intermediate-mass regimes and in massive galaxies' kinematics, require further investigation. We compare our results to other attempts to mock similar observations, all of smaller data sets. Our final dataset will be released with the publication, consisting of >10,000 post-processed data-cubes analysed with pyPipe3D, along with the codes developed to create it.

Corrections to Bekenstein-Hawking entropy --- Quantum or not-so quantum?

description: Hawking radiation and Bekenstein--Hawking entropy are the two robust predictions of a yet unknown quantum theory of gravity. Any theory which fails to reproduce these predictions is certainly incorrect. While several approaches lead to Bekenstein--Hawking entropy, they all lead to different sub-leading corrections. In this article, we ask a question that is relevant for any approach: Using simple techniques, can we know whether an approach contains quantum or semi-classical degrees of freedom? Using naive dimensional analysis, we show that the semi-classical black-hole entropy has the same dimensional dependence as the gravity action. Among others, this provides a plausible explanation for the connection between Einstein's equations and thermodynamic equation of state, and that the quantum corrections should have a different scaling behavior.

description: The Hamiltonian structures of several hybrid kinetic-fluid models are identified explicitly, upon considering collisionless Vlasov dynamics for the hot particles interacting with a bulk fluid. After presenting different pressure-coupling schemes for an ordinary fluid interacting with a hot gas, the paper extends the treatment to account for a fluid plasma interacting with an energetic ion species. Both current-coupling and pressure-coupling MHD schemes are treated extensively. In particular, pressure-coupling schemes are shown to require a transport-like term in the Vlasov kinetic equation, in order for the Hamiltonian structure to be preserved. The last part of the paper is devoted to studying the more general case of an energetic ion species interacting with a neutralizing electron background (hybrid Hall-MHD). Circulation laws and Casimir functionals are presented explicitly in each case.

description: Fast scrambling, quantified by the exponential initial growth of Out-of-Time-Ordered-Correlators (OTOCs), is the ability to efficiently spread quantum correlations among the degrees of freedom of interacting systems, and constitutes a characteristic signature of local unstable dynamics. As such, it may equally manifest both in systems displaying chaos or in integrable systems around criticality. Here, we go beyond these extreme regimes with an exhaustive study of the interplay between local criticality and chaos right at the intricate phase space region where the integrability-chaos transition first appears. We address systems with a well defined classical (mean-field) limit, as coupled large spins and Bose-Hubbard chains, thus allowing for semiclassical analysis. Our aim is to investigate the dependence of the exponential growth of the OTOCs, defining the quantum Lyapunov exponent $λ_{\textrm{q}}$ on quantities derived from the classical system with mixed phase space, specifically the local stability exponent of a fixed point $λ_{\textrm{loc}}$ as well as the maximal Lyapunov exponent $λ_{\textrm{L}}$ of the chaotic region around it. By extensive numerical simulations covering a wide range of parameters we give support to a conjectured linear dependence $2λ_{\textrm{q}}=aλ_{\textrm{L}}+bλ_{\textrm{loc}}$, providing a simple route to characterize scrambling at the border between chaos and integrability.

description: We study the spatial decoherence dynamics for the relative position of two atoms in a singlemode ring cavity. We find that the spatial decoherence of the two atoms depends strongly on their relative position. Taking into account the spatial degrees of freedom, we investigate the entanglement dynamics of the internal states of the two atoms. It is shown that the entanglement decays to almost zero in a finite time, and the disentanglement time depends on the width of the wave packets describing the atomic spatial distribution.

description: Infrared and visible image fusion plays a vital role in the field of computer vision. Previous approaches make efforts to design various fusion rules in the loss functions. However, these experimental designed fusion rules make the methods more and more complex. Besides, most of them only focus on boosting the visual effects, thus showing unsatisfactory performance for the follow-up high-level vision tasks. To address these challenges, in this letter, we develop a semantic-level fusion network to sufficiently utilize the semantic guidance, emancipating the experimental designed fusion rules. In addition, to achieve a better semantic understanding of the feature fusion process, a fusion block based on the transformer is presented in a multi-scale manner. Moreover, we devise a regularization loss function, together with a training strategy, to fully use semantic guidance from the high-level vision tasks. Compared with state-of-the-art methods, our method does not depend on the hand-crafted fusion loss function. Still, it achieves superior performance on visual quality along with the follow-up high-level vision tasks.

description: Writing  well  is  not  just  an  option  for  young  people—it  is  a  necessity.  Along  with  reading
comprehension, writing skill is a predictor of academic success and a basic requirement for
participation in civic life and in the global economy. Writing skills are an important aspect of
academic  performance  as  well  as  subsequent  work-related  performance. The  objectives  of
this study were to investigate teachers’ and students perceptions of students’ performance in
writing skills in secondary schools of Arba-Minch town. To guide the study four research
questions were posed. The questions examined the following three variables: (1) Planning;
(2) Practice; and (3) Addressing feed-back for writing skills. A descriptive design with mixed
approaches (quantitative and qualitative) was used for the study. A total of 291 secondary
school grade ten students and 15 secondary school English language teachers participated in
the  study.  A  simple  random  sampling  technique  was  used  to  select  schools  and  students
participants.  Questionnaire  that  contained  items  on  planning,  practicing  and  addressing
feed-back, variables was used by the researcher to collect information from both the students
and  teachers.  A  necessary  data  from  15  teachers  were  collected  through  close  ended  and
open  ended  questionnaires  and  on  the  same  issues  data  was  collected  from  252  students.
Interview  with  4  teachers  and  FGD  with  39  students  were  also  conducted  to  collect  data.
One sample t- test, and step wise multiple regression analysis were conducted to analyze the
data. The findings indicate that teacher’s perception show that students didn’t use planning,
practice,  and  giving  /receiving  feed-back  for  their  writing  performance.  In  the  same  way,
students themselves perceived as they didn’t plan, practice, and give/receive feed-back for
their better performance in writing. Findings from informants and discussants indicated as
learning  grammar,  capitalization,  punctuation,  orienting/listening  about  writing  rules
enhance  students’  performance  in  writing, whereas  lake  of  interest,  motivation,  initiation,
absenteeism, failure to listen to their teachers and failure to do writing assignments, mother
tongue influence, pragmatic competence of learners material and unmanageable class size,
strategies use, cohesions, and coherence stated that hinder their (students) performance in
writing.
EXPLORING STUDENTS’ READING COMPREHENSION  WITH PARTICULAR REFERENCE TO PREPARATORY SCHOOL ARBA MINCH UNIVERSITY SCHOOL OF POST GRADUATE STUDIES COLLEGE OF SOCIAL SCIENCES AND HUMANITIES DEPARTMENT OF ENGLISH LANGUAGE  LITERATURE EXPLORING STUDENTS’ READING COMPREHENSION PROBLEMS WITH PARTICULAR REFERENCE TO JENBORO SECONDARY AND  PREPARATORY SCHOOL

description: The principal intent of this study was to explore students’ reading comprehension problems at
Jenboro Secondary and Preparatory School in Gummer Woreda, Guraghe Zone. To this end, a
descriptive survey research was employed to achieve this research goal. Special reference was
given for preparatory grades. Sample sizes of hundred students were taken for the study. A 68-item  survey  questionnaire  were  designed  and  administered  to  secure  relevant  data  from  the
students. The data collected through the questionnaire were analyzed with descriptive statistics
(frequency  and  percentage).  All  the  collected  data  were  analyzed  and  discussed to  arrive  at
conclusions. Findings  indicated  that  students  in  the  school  under  the  study  seem  to  have  had
serious  reading  comprehension  problems.  Accordingly, lack  of  word-attack  skills, inability  to
guess  from  context,  inadequate  knowledge  of the English  language  vocabulary  and  teachers
ineffective methods of teaching reading were the most common and frequent students’ reading
comprehension  problems.  Inadequate  training  in  reading  skill,  failure  to  read  frequently  and
extensively,  lack  of  interest  in  reading,  language  difficulty  in  a  text  and  excessive  use  of
dictionary were the next frequent problems and shortage of the English language reading books
and supplementary materials, inadequate library service, and bad home living environment were
ear  marked  problems  coming  third.  Thus,  the  result  of  the  study  generally  suggests  that  the
sources of the problem mostly come from the teachers and students. The teachers’ practice of
teaching reading did not appear to provide students with helpful learning atmosphere in order to
practice  reading  and  to  develop  their  own  reading  comprehension. The  students  also  lack
frequent  reading  habit  and  interest. Consequently,  teaching  and  learning  reading  seemed  to
suffer from different problems created at various sources. Based on these findings, to alleviate
the  problems  it  was  recommended  that students  need  word-attack  skills,  we  need  to  provide
students  a  text  with  adequate  clues  towards  a  meaning  of  a  target  word,  students  should  be
convinced  that  guessing  from  context  is  a  meaningful  and  interactive  learning  process, and
teachers should appropriately employ the process of teaching reading and so on.

description: With the aim of measuring the $^{235}$U(n,f) cross section at the n\_TOF facility at CERN over a wide neutron energy range, a detection system consisting of two fission detectors and three detectors for neutron flux determination was realized. The neutron flux detectors are Recoil Proton Telescopes (RPT), based on scintillators and solid state detectors, conceived to detect recoil protons from the neutron-proton elastic scattering reaction. This system, along with a fission chamber and an array of parallel plate avalanche counters for fission event detection, was installed for the measurement at the n\_TOF facility in 2018, at CERN. An overview of the performances of two RPTs - especially developed for this measurement - and of the parallel plate avalanche counters are described in this article. In particular, the characterization in terms of detection efficiency by Monte Carlo simulations and response to neutron beam, the study of the background, dead time correction and characterization of the samples, are reported. The results of the present investigation show that the performances of these detectors are suitable for accurate measurements of fission reaction cross sections in the range from 10 to 450~MeV.

description: The main purpose of this study was to investigate vocabulary and grammar learning strategies
used by good and poor language learners. The focal point of the study was to see similarities and
differences  between  good  and  poor  language  learners  in  using  vocabulary and  grammarlearning strategies. Both questionnaire and interview used to collect data.  Questionnaire was
adopted from Oxford’s 1990 model. The questionnaire was administered to 86 good and 86 poor
language learners at Arba Minch comprehensive, Chamo Secondary and Preparatory and Kola
Shele high school. The frequency and t-test were used to analyze the data. The frequency was
used  to  describe  the  information  taken  from  the  questionnaire.  The  t-test  (with  significant
difference level P<0.05) was applied to check if there was a statistically significant difference
between  good  and  poor  language  learners  in  using  each  sub-category  of  vocabulary  and
grammar learning strategies.
The finding shows that there was a wide difference between vocabulary and grammar learning
strategies use except social strategy. Good language learners use more vocabulary and grammar
learning strategies than poor language learners.
