Authors: Ammar Samar Reda , Ghazy Medhat A. , Mabrouk Maaly M. , Gawaly Amr M. 
Published: April 2022

CONTEXT:
One of the most common extra-intestinal signs of ulcerative colitis (UC) disease is anemia, which has a significant influence on patients' quality of life.

AIM:
The aim was to evaluate the role of serum hepcidin and reticulocyte hemoglobin concentration (CHr) in the study of anemia in UC patients.

SUBJECTS AND METHODS:
We recruited 80 UC patients and 30 healthy individuals of matched age and sex as controls. Subjects were subdivided into three groups – Group I: 50 anemic UC patients, Group II: 30 nonanemic UC patients, and Group III: 30 healthy controls.

RESULTS:
CHr showed a statistically highly significant decline in Group I than Groups II and III. Serum hepcidin showed a significant difference between Groups I, II, and III. We reported a significant negative correlation between CHr and severity of UC and extension of UC and a significant positive correlation between CHr and hemoglobin level, mean corpuscular volume (MCV), serum ferritin, and transferrin saturation. While, serum hepcidin had a significant negative correlation with severity and extension of UC and a significant positive correlation with hemoglobin level, MCV, serum ferritin, transferrin saturation, and CHr.

CONCLUSIONS:
CHr had an excellent performance in prediction of iron-restricted anemia and was the test of best performance in prediction of iron-deficiency anemia ± ACD. Serum hepcidin had an excellent performance in prediction of ACD.

Authors: Mones Hayfaa Mohammed , Hassan Meaad Kadhum , Al Hussein Ahmed Bahaa Abd 
Published: April 2022

BACKGROUND:
Sickle cell disease (SCD) is a chronic multisystem disorder associated with acute and chronic complications that may negatively impact the quality of life (QoL). The study aimed to assess the health-related QoL (HRQoL) of patients with SCD on hydroxyurea (HU) and the factors affecting HRQoL domains.

MATERIALS AND METHODS:
This case-control study included 174 patients with SCD (12–18-year-old); 87 were on HU for at least 1 year and 87 were not receiving HU. It also included 174 healthy adolescents of the same age group. The HRQoL was assessed using the Short Form 36 Health Survey version 2 (SF-36v2). A multivariate linear regression analysis was performed to assess the independent effect of studied variables on HRQoL dimensions.

RESULTS:
Patients with SCD who were not on HU were found to have significantly lower SF-36 v2 scores (all domains) compared to those on HU and control group, P < 0.001. While patients on HU had significantly lower SF-36 v2 scores in physical functioning, role physical (RP), general health, and physical health component score only compared to the control group, P < 0.001. Multivariate linear regression analysis revealed significant associations between duration of HU therapy and RP (R2 = 0.208, P = 0.021) and mental health component score (R2 = 0.389, P = 0.047) and between hemoglobin levels with social functioning (R2 = 0.370, P = 0.023).

CONCLUSIONS:
HU has improved the HRQoL of SCD patients, in almost all domains, in addition to the improvement in many disease-related complications, mainly painful episodes. The positive impact of HU on HRQoL was significantly associated with the duration of therapy.

Published: April 2022

Background/Objectives:
Migrations are among the most complex social phenomena in the history of mankind. In Latin America, the Venezuelan migration (VM) of the last two decades has altered the emotional dynamics of the migrant themselves and the populations of host countries such as Colombia, Ecuador, and Perú. In order to point out strategies of management and prevention, this review examines the sociocultural variables at play during the process, and the main mental health problems faced by the VM protagonists in these three Andean countries. Methods: This is a narrative/scoping review of diverse and reliable information sources about the VM in the three countries. Data are grouped in two sections: sociocultural variables and specific mental health impact.

Results:
Findings reflect both qualitative and quantitative information about reasons to migrate, educational level, living conditions and response from host communities, as well as mental illnesses prevalence related to experiences such as victimization by discriminatory/xenophobic behaviors, criminalization, and abuses.

Conclusions:
The impact of the VM has been intense and multiform on both migrant and host populations, unveiling individual, collective, social/community, and government/administrative vulnerabilities. National and international agencies must propitiate collaborative research and public/mental health initiatives for a better management of general and specific aspects of the process.

The breeding system of Hyacinthoides non-scripta (Asparagaceae): assessing the role of geitonogamy with captive pollinators
Authors: Guitián Javier , Guitián Pablo 
Published: April 2022

Background and aims – In self-incompatible species, geitonogamous pollen deposition can result in stigma clogging, with negative effects on cross-fertilisation and subsequently reduced fruit and seed set. In this work, using laboratory and field experiments with pollinators in captivity, we describe the reproductive system of Hyacinthoides non-scripta and analyse the effect of the different mechanisms of pollen transfer, trying to quantify the effect of geitonogamy on the reproductive success of the species.
Material and methods – Using laboratory and field experiments with pollinators in captivity we evaluated the effect of the different types of pollen transfer.
Key results – The results show that H. non-scripta is a self-incompatible species and the pollen tubes in autogamous and geitonogamous pollination are rejected at the base of the style. In the field experiments, the presence of geitonogamous pollen on the stigma did not prevent subsequent fertilization by xenogamous pollen, but it reduced seed production.
Conclusion – This study provides evidence that natural rates of geitonogamy significantly reduce female fitness in plants with large numbers of flowers per inflorescence and show how experiments with captive pollinators can help quantify the intensity of this effect.

Preschool teachers’ ability to manage problem behaviours in their classroom: can it be predicted by teacher self-efficacy and emotional literacy
Authors: DURMUŞOĞLU SALTALI Neslihan 
Published: April 2022

Objective: Management of problematic behaviors (MPB) in the classroom is one of the important components of the teaching process and it is among the issues that teachers worry about in the education process. Preschool teachers often encounter problematic behaviors as the cognitive, emotional, and behavioral development processes of children in their classrooms are still incomplete. Therefore, it is important to examine preschool teachers' ability to MPB and to determine the related factors. The aim of this descriptive study determined the relationship of preschool teachers' ability to MPB in their classrooms to teacher self-efficacy and emotional literacy.
Method: The sample of the study consists of 381 preschool teachers (working in schools affiliated to the Ministry of National Education in different cities of Turkey. Preschool Classroom Management Scale, Emotional Literacy Scale and Teacher Self-Efficacy Scale were used to collect data. Descriptive statistics, Pearson correlation analysis and multiple regression analysis techniques were used to analyse the data.
Results: This study confirms that preschool teachers' ability in MPB in their classrooms are moderately related to emotional literacy skills. In addition, it was determined that there is a moderate relationship between the ability of preschool teachers to MPB in their classrooms and their teacher self-efficacy.
Conclusion: The findings draw our attention to the importance of teachers' efficacies and emotional abilities in improving schools and the general teaching environment.
MESMER-M: an Earth system model emulator for spatially resolved monthly temperature
Authors: Nath Shruti , Lejeune Quentin , Beusch Lea , Seneviratne Sonia I. , Schleussner Carl-Friedrich 
Published: April 2022

Abstract. The degree of trust placed in climate model projections is commensurate with how well their uncertainty can be quantified, particularly at timescales relevant to climate policy makers. On inter-annual to decadal timescales, model projection uncertainty due to natural variability dominates at the local level and is imperative to describing near-term and seasonal climate events but difficult to quantify owing to the computational constraints of producing large ensembles. To this extent, emulators are valuable tools for approximating climate model runs, allowing for the exploration of the uncertainty space surrounding selected climate variables at a substantially reduced computational cost. Most emulators, however, operate at annual to seasonal timescales, leaving out monthly information that may be essential to assessing climate impacts. This study extends the framework of an existing spatially resolved, annual-scale Earth system model (ESM) emulator (MESMER, Beusch et al., 2020) by a monthly downscaling module (MESMER-M), thus providing local monthly temperatures from local yearly temperatures. We first linearly represent the mean response of the monthly temperature cycle to yearly temperatures using a simple harmonic model, thus maintaining month-to-month correlations and capturing changes in intra-annual variability. We then construct a month-specific local variability module which generates spatio-temporally correlated residuals with yearly temperature- and month-dependent skewness incorporated within. The emulator's ability to capture the yearly temperature-induced monthly temperature response and its surrounding uncertainty due to natural variability is demonstrated for 38 different ESMs from the sixth phase of the Coupled Model Intercomparison Project (CMIP6). The emulator is furthermore benchmarked using a simple gradient-boosting-regressor-based model trained on biophysical information. We find that while regional-scale, biophysical
feedbacks may induce non-uniformities in the yearly to monthly temperature downscaling relationship, statistical emulation of regional effects shows comparable skill to the more physically informed approach. Thus, MESMER-M is able to statistically generate ESM-like, large initial-condition ensembles of spatially explicit monthly temperature fields, providing monthly temperature probability distributions which are of critical value to impact assessments.
Improved runoff simulations for a highly varying soil depth and complex terrain watershed in the Loess Plateau with the Community Land Model version 5

Published: April 2022

Abstract. This study aimed to improve runoff simulations and explore deep
soil hydrological processes for a watershed in the center of the Loess
Plateau (LP), China. This watershed, the Wuding River Basin (WRB), has very
complex topography, with soil depths ranging from 0 to 197 m. The
hydrological model used for our simulations was Community Land Model version 5 (CLM5) developed by the National Center for Atmospheric Research. Actual
soil depths and river channels were incorporated into CLM5 to realistically
represent the physical features of the WRB. Through sensitivity tests, CLM5
with 150 soil layers with the observed variable soil depths produced the
most reasonable results and was adopted for this study. Our results showed
that CLM5 with actual soil depths significantly suppressed unrealistic
variations of the simulated subsurface runoff when compared to the default
simulations. In addition, when compared with the default version with 20
soil layers, CLM5 with 150 soil layers slightly improved runoff simulations
but generated simulations with much smoother vertical water flows that were
consistent with the uniform distribution of soil textures in our study
watershed. The runoff simulations were further improved by the addition of
river channels to CLM5, where the seasonal variability of the simulated
runoff was reasonably captured. Moreover, the magnitude of the simulated
runoff remarkably decreased with increased soil evaporation by lowering the
soil water content threshold, which triggers surface resistance. The lowered
threshold was consistent with the loess soil, which has a high sand
component. Such soils often generate stronger soil evaporation than soils
dominated by clay. Finally, with the above changes in CLM5, the simulated
total runoff matched very closely with observations. When compared with
those for the default runoff simulations, the correlation coefficient,
root mean square error, and Nash–Sutcliffe coefficient for the improved
simulations changed dramatically from 0.02, 10.37 mm, and −12.34 to 0.62,
1.8 mm, and 0.61. The results in this study provide strong physical insight
for further investigation of hydrological processes in complex terrain with
deep soils.
Measuring Financial Reporting Harmony and Harmonisation: Perception Versus Reality
Authors: Pierce Aileen , Weetman Pauline 
Published: April 2022

Techniques for measuring harmony and harmonisation of financial reporting, applied in the literature since 1988, include index-based techniques and statistical models. As empirical evidence increases and the limitations of the models become apparent, the question is raised as to whether we actually observe harmony and harmonisation in seeking to measure these concepts. Although it has been acknowledged in the literature that statistical models measure a different concept of harmony to that measured by indices, the variety of index measures available to measure both national and international harmony has not been comprehensively explained or rationalised. In this paper various index measures are evaluated critically and the notion of harmony underpinning each is explored in the context of incomplete information due to non-disclosure. Formulae previously applied are developed further to incorporate the specific impact of accounts categorised as not applicable on the index measures. Index-based measures are calculated for actual accounts data relating to deferred tax accounting practices in Ireland and Denmark in order to highlight differences in levels of harmony indicated by competing measures of both national and international harmony. Conclusions are drawn that non-disclosure is a serious impediment to research and policy formation in relation to harmonisation of accounting practices and that refilling the formulae, while helping to quantify the problem more precisely, serves to emphasise the importance of careful specification of the research question before selecting the harmonisation measurement technique.
Autoaprendizaje: solipismo o acompañamiento académico
Authors: Pacheco- Sosa Carolina 
Published: April 2022

This paper addresses the subject of
self-learning, and it underscores the paramount
importance of guidance for its development during
the processes of teaching and learning. The concept
of “self-learning” encompasses three main abilities:
autonomy, metacognition, and self-regulation, which
lead to a self-learning process. This definition has
roots in the teaching theory, and all its elements are
linked to the self-learning abilities underlying. It is
vital to state that the great importance of the teacher
role during this process, since they will provide all the
necessary learning tools for the students to become
active during the learning process. Therefore, it is
confirmed that the self-learning process is not a path
for the student to walk alone; a guidance is required
for its development. Similarly, to acquire self learning
abilities will allow students to achieve an
active role during the learning process, which will
also lead to develop a critical thinking. As a result,
students will not only acquire abilities for academical
purposes, but also a set of personal and professional
skills. Likewise, some teaching practices that can
be adopted to support the self-learning process are
procured.
Tensiones del discurso de la inclusión educativa
Authors: Molina-Padilla Norma Angélica 
Published: April 2022

The article reflects on how inclusion has
positioned itself as a common language within the
educational system, mainly within human rights, as
a promise of justice before those people who had
historically remained on the margins. That is, the so called
vulnerable groups. However, it seems that the
compromise is not reached, on the contrary, it looks
distant and alien. From that context, we discuss
with some educational thinkers who have striven
to understand, and above all ask themselves other
questions, that will probably help redirect the course
of inclusion. This in order to make visible that there
are other possibilities to educate, even beyond this
paradigm. In short, interdisciplinary dialogue, the
transgression of educational boundaries, as well as
stressing the paradigm enable us to imagine other
forms of action that are more just and plural.
