Published: July 2022

Objective: Poor adherence to antihypertensive medication occurs in 50%-80% of patients. An ongoing randomized controlled trial (RCT) is evaluating a personalized mobile-health intervention in poorly adherent hypertensive persons with bipolar disorder. To enhance efficacy, the ongoing trial elicited guidance from a Stakeholder Advisory Board (SAB) comprised of patients, family members, clinicians, and health system administrators. Our goal is to describe the formation, role, decision-making process, and key contributions of the SAB as a means of demonstrating meaningful community engagement in mental health research.Methods: Using models and measures from the field of implementation science, eleven SAB members convened across three meetings followed by quantitative surveys that assessed SAB member satisfaction and engagement during the meetings.Results: Significant suggestions from the SAB included 1) expanding inclusion/exclusion criteria, and 2) operationalizing remote implementation of the RCT. Primary study implementation challenges identified by the SAB were 1) participant difficulty engaging in the mHealth intervention, and 2) identification of procedures for monitoring participant adherence to the RCT protocol and contacting under-engaged participants. Quantitative surveys indicated that all SAB members believed that the objectives of the meetings were clear, perceived that they were able to participate in the discussions, and that they were heard.Conclusions: Increasing evidence demonstrates the feasibility of engaging with SABs in clinical research and that this process improves intervention design, increases participant engagement, reduces mental health-related stigma, and produces more effective implementation strategies. We encourage future investigators to use an implementation science framework in partnership with SABs to refine their proposed interventions and improve clinical outcomes.

The COVID-19 pandemic and lockdown disrupted every human endeavour including the world of medical education, halting pre-clinical and clinical trainings as well as graduation of physicians for the healthcare workforce thus posing a double jeopardy at a time of dire need for increased healthcare personnel. The adaptability and preparedness of training curricula for emergencies such as natural and man-made disasters ultimately determine the degree of disruption in medical education. This study explored students’ insights on the efficacy and suitability of two curriculum pathways before and during the COVID-19 pandemic. This is a descriptive, cross-sectional study conducted between 2020 and 2021 in a public medical school using 102-item questionnaire administered online to 300 medical and dental students exposed to different training curricula- a “Traditional Curriculum”, and a new “SPICCES Curriculum” that emphasizes student-centred designs. The questionnaire response rate was 93.3% comprising 55.7% and 44.3% female and male respondents, and 78.6% and 21.4% medical and dental students respectively with a mean age of 22.1 ± 2.39 years (range: 18-33 years). A total of 65.4% and 34.6% respondents were on the SPICCES and Traditional curriculum pathways respectively. More respondents in the SPICCES curriculum compared with the traditional curriculum track (70.5% vs 52.6%; χ2 = 8.862, p = 0.003, φ = -0.178) had favourable perspectives on the relevance of their program and the overall quality of the curriculum in preparing them to be rounded physicians for the 21st-century (59.0% vs 27.8%). Approximately 47.0% and 33.0% (χ2 = 3.990, p = 0.046, φ = -0.119) respondents in dentistry and medicine respectively had unfavourable perception about the relevance of the SPICCES curriculum. Findings in this study echo the need for student-centred curriculum designs and conducive educational environments that are resilient to emerging and established threats to educational pedagogy and programs. The study highlights the need for programs that support social and extracurricular activities for students.
A new neurocomputing approach for medium-range temperature prediction
Authors: NASKAR PRAVATRABI , NASKAR SOMNATH
Published: July 2022

To predict medium-range temperature with appreciable accuracy this study has been undertaken. We have tried to predict max-min temperature time series (signal) 5, 7 and 9 days ahead with the help of a new machine learning (neurocomputing) technique. Variational Mode Decomposition (VMD) has been used to decompose temperature time series and decomposed modes obtained from VMD have been individually used as input to Long Short Term Memory (LSTM). The LSTM predicted the modes individually and predicted modes are combined to generate the predicted signal. The signal predicted by this method closely matches with the actual test signal and minimizes the error in predicting the signal.

Published: July 2022

An analysis was carried out to study the rainfall variability and its probability for different categories of rainfall events (2.5-25, 25-50, 50-75, 75-100 and >100 mm) in Punjab during the period (1971-2011). The rainfall showed decreasing trend in Ludhiana, Roop Nagar, Hoshiarpur and Ferozpur representing different agroclimatic zones of the state. The probability of rainfall at different level of significance (90, 75, 50, 25, 10%) was computed and it was found that the highest probability rainfall was observed at 10% level and lowest rainfall probability was observed at 90% level of confidence. The study of drought indicated that the frequencies of drought were reported 4 times in Faridkot, 4 times in Mukatsar, 3 times in Ludhiana, 3 times in Sangrur and 3 times in Moga.
ki and naki - Alternative Question Particles in Bangla
Authors: Guha Ambalika
Published: July 2022

The primary discussion of the paper is centered on two polar question particles in the Eastern Indo-Aryan language Bangla. One is ‘ki’ and the other one is ‘naki.’ These two polar question particles also appear as interrogative disjunction morphemes in alternative questions. This further leads to the argument that there exists a disjunction operator in both polar and alternative questions and the polar question particle is the lexical realization of that disjunction operator.

Published: July 2022

The aim of this research is to investigate the precursor relationship between values, attachment styles, and appearance anxiety of married individuals. Structural equation modeling analysis has been carried out in order to test the relationship among values, attachment, and social appearance anxiety variables in the research. Structural equation modeling analysis has been carried out with AMOS 19 program. In the research, the “Personal Information Form” to collect the necessary data, the “Values Scale'' to determine the values of married individuals, ''Experiences in Close Relationships Inventory-I'' to determine the attachment styles of married individuals, and "Social Appearance Anxiety" scales to determine appearance anxiety were used. Percentage and frequency calculations of the collected data have been created with the SPSS 18 package program. According to the analysis results obtained from the study, it has been seen that there is a meaningful negative relationship when the precursor relationships between values and appearance anxiety are examined. In other words, it has been concluded that as the values of individuals increase, their appearance concerns will decrease. Additionally, when the precursor relationships between attachment styles of married individuals and appearance anxiety are examined, it has been determined that there is a positive linear relationship. Accordingly, it has been determined that individuals' attachment styles will positively affect their appearance anxiety.

Review of Literature is Foundation and Blood of Research
Authors: Ahmad Dar Showkat , Sakhtivel P.
Published: July 2022

You must learn how to produce a solid literature review if you want to have a successful academic or even professional career. The capacity of a student to summarise and synthesise previous research on a topic not only demonstrates that they have a good grasp on the available knowledge, but it also benefits in their learning process. Literature reviews are frequently misinterpreted and underdeveloped, despite their importance. The goal of this article is to help researchers learn how to do a literature review and how to enhance their writing skills. This section includes discussions on the structure, technique, and art of literary reviews. Tertiary students may be required to write a critical literature review at the undergraduate or postgraduate level. The literature review serves to identify your study as part of a thesis or research paper by outlining baseline facts, as well as where you agree or disagree with previous work and how your work adopts or rejects other people's methods. According to Shuttleworth (2016), a literature review can serve as a precursor or guide in the introduction of a research paper, as well as a complete paper in its own right. It is frequently used as the first stage of large research projects, allowing the supervisor to determine whether the student is on the right track. The writing or design of a review of literature is currently a major source of worry among Indian scholars; nevertheless, universities lack a uniform setup or approach for reviewing literature. Thus, the study's goal is to highlight the design, length, and value of a literature review for thesis work or article construction, as well as to provide essential recommendations for the aforementioned difficulties.

«Vivir los días usados». Eduardo Zamacois en el exilio (1939-1971)
Authors: Martínez Vilches David
Published: July 2022

En enero de 1939 el novelista Eduardo Zamacois y su familia abandonaban España camino del exilio. Este artículo analiza la experiencia del fenómeno exílico por parte de este autor como una trayectoria que comienza con una razón de exilio y finaliza con la muerte del escritor en Buenos Aires. Sin embargo, el exilio de Zamacois no contempla una única dimensión traumática entre ambos momentos. Por el contrario, también es la historia de una reconstrucción vital, de una nue­va manera de publicar en el país de origen y, sobre todo, de una nue­va concepción del paso del tiempo.

Ensemble Forecasting of Return Flow over the Gulf of Mexico

Published: July 2022

Errors in operational forecasts of return flow events (RFEs) over the Gulf of Mexico have dictated the search for sources of these errors. Based on earlier studies, likely candidates for these errors are: incorrect parameterization of turbulent transfer processes at the air-sea interface, uncertain vertical motion above the mixed layer, and incorrect initial conditions. We investigate these possible sources of error by performing numerical experiments with a Monte Carlo ensemble prediction model applied to a well-observed case in February 1988. In essence, we examine uncertainty in prediction due to uncertainty in the model’s elements of control. A mixed-layer model with roughly 50 elements of control is used to determine forecast uncertainty due to initial conditions alone, boundary conditions alone, parameterization alone, as well as the full complement of uncertainty in these elements of control. The uncertainty is calculated at points along a predetermined outflow trajectory that originates over shelf waters in the northeastern Gulf, passes north of the Yucatan Peninsula, and terminates in the west-central Gulf-all points along the trajectory are characterized by convective heating at the sea-air interface. Results from the numerical experiments led to the following results: 1) parameterization of physical processes exerts the greatest influence on forecast uncertainty, and 2) the water-vapor mass in the mixed-layer column is uncertain by a factor of two at the trajectory’s terminal point. The latter result confirms forecasters’ long-held view that vapor return is the most suspect product in operational prediction of RFEs. In addition to these numerical experiments with the 1988 case, a recent RFE is examined in the context of operational model performance at the National Center for Environmental Prediction (NCEP). The paper ends with discussion of steps to be taken that hold promise for improved operational prediction of RFEs over the Gulf of Mexico.
A Multi-scale Analysis of the Atmospheric Conditions Associated with the Daytona Beach Tornado of Christmas Day, 2006
Authors: Lanicci John M.
Published: July 2022

This case study describes a severe-storm event over Florida, Georgia, and South Carolina on 25 December 2006, with a particular focus on an F2 tornado that struck Daytona Beach, FL and caused over $50 million in damages.  The severe weather occurred over a 12-h period and was associated with a deep upper-level trough and surface front moving through the southeastern U.S.  Morning soundings over Florida showed low to moderate CAPE and strong vertical wind shear, consistent with seasonal composite tornadic soundings for the region.  A quasi-linear convective system moved onshore near Tampa during the midmorning hours, the northern half of which accelerated and produced bow echoes that resulted in two tornadoes and nontornadic wind damage over Pasco, Sumter, and Lake Counties between 1620 and 1725 UTC.  This portion of the line then moved into Volusia County and spawned F2 tornadoes in Deland and Daytona Beach after 1800 UTC.  Data from the Melbourne National Weather Service Forecast Office’s Weather Surveillance Radar-1988D (WSR-88D), Daytona Beach International Airport (DAB) Automated Surface Observing System (ASOS), and DAB Low Level Wind Shear Alert System (LLWAS) were integrated to analyze conditions at the east end of the DAB runway 7L/25R complex, where the tornado first appeared.  The LLWAS is normally used by air traffic control personnel for monitoring airport wind-shear conditions.  The 10-s LLWAS wind data filled critical temporal and spatial gaps in the WSR-88D and ASOS data, and captured evidence of strong winds and cyclonic curvature nearly coincident with the locations of the radar-identified velocity couplet and tornado itself.
Remotely Visible Width and Discontinuity of 50 Tornado Damage Paths through Forested Landscapes
Authors: Zenoble Mark D. , Peterson Chris J.
Published: July 2022

Tornado damage-path width is a necessary component for calculation of area impacted, which allows estimation of hazards. To date, rarely has variation in damage path width or path discontinuity been a focus. In this paper, using a damage threshold of >25% canopy damage, we quantify width and discontinuity in 50 tornado paths in forested areas. Tornado-path starting and end points were overlaid on Google Earth imagery obtained ≤24 months after the tornadoes, and damage-path width (or absence of damage) was measured for severities >25% canopy loss, at fixed intervals. Width was measured only where both sides of the damage path were clearly defined by forest tree damage, thus many points were excluded from our analysis. Given our threshold level of forest canopy damage, no EF0 tornadoes showed remotely visible damage, and analyses were thus restricted to ≥EF1 tornado paths. Variation in remotely visible damage width was quantified as coefficient of variation, which ranged from 0.227 to 0.852, with a mean of 0.531 among the 50 paths. Discontinuity in remotely visible damage also varied among damage paths; up to 45% of the total number of measured points within a path lacked visible damage. Almost 40% of tornado damage paths exhibited such discontinuity along 20% or more of their path length. We suggest that the long, narrow EF-scale contours (particularly for ≥EF1) often reported after storm surveys may mask extensive width variation in severe damage and substantial portions of tornado paths with no severe damage.
A Significant Tornado in a Heterogeneous Environment During VORTEX-SE
Authors: Coleman Timothy A. , Lyza Anthony W. , Wyatt Wes
Published: July 2022

On 1 March 2016, an EF2 tornado occurred near Birmingham, AL, and was examined as part of VORTEX-SE. The boundary-layer environment near the tornadic supercell was heterogeneous in space and unsteady in time, with what typically would be considered an excellent proximity sounding. In this case, however, the proximity sounding severely underestimated the CAPE. SPC mesoanalyses substantially underestimated the CAPE and wind shear as well. Tornadogenesis occurred near a weak, frontogenetical thermal boundary, where evaporation from antecedent light showers had also increased dewpoint values. A local maximum in surface dewpoint (and instability), and a local maximum in helicity both existed near the region of frontogenesis. As a QLCS moved into the region of higher CAPE air, part of it became supercellular. Tornadogenesis occurred near the local maximum in surface dewpoint.
A Multi-Platform Reanalysis of the Kankakee Valley Tornado Cluster on 30 June 2014

Published: July 2022

Two derecho-producing quasi-linear convective systems moved across northeast Illinois and northwest Indiana on the evening of 30 June 2014. Both produced damage across a large area, including a concentrated cluster in the Kankakee River Valley associated with two long-lived and adjacent mesovortices in the second derecho. Post-event surveys of this region revealed a widespread, complex damage pattern and initially documented 14 tornadoes of EF1 rating on the Enhanced Fujita (EF) Scale, along with a swath of damaging nontornadic winds. Later, a number of uncertainties from the original surveys were examined in conjunction with high-resolution satellite imagery not available immediately after the event. Inconsistencies noted during this process led to an intensive reanalysis of the entire cluster using radar data, the original ground and aerial surveys, and the newly available satellite imagery. This new analysis concluded that at least 18 tornadoes impacted the Kankakee Valley, most with a path orientation different from the initial results. This paper details the reassessment process from initial motivation to final results, addresses potential sources of error, and discusses operational considerations stemming from such a prolifically tornadic event.

Thunderstorms formed in the afternoon of 17 April 2019 over northern Mexico.  Satellite data are used to highlight several features associated with convective preconditioning over portions of Coahuila, Mexico.  Satellite imagery was used to identify two preconvective features over northern Coahuila:  1) A relatively moist boundary layer inferred from channel differencing of imagery near 10.3 µm and 12.3 µm, and 2) Upward vertical motion inferred from decreasing values of brightness temperatures near 7.34 µm (low-level water vapor).  Due to the approach of a trough at 500 hPa, a larger region of cooling was evident in low-level water vapor imagery.  Evidence of blowing dust in imagery was used to highlight a wind-shift boundary along with a possible region of enhanced horizontal convergence.  A demonstration of a time-of-arrival tracking feature is used to show a benefit to a forecaster in determining the arrival of a region of blowing dust, possible enhanced horizontal convergence and subsequent convective initiation.  Assimilation of satellite data that contains key features and potential benefits to numerical weather prediction is addressed.  Convective preconditioning of an environment outside of the United States, but adjacent to a U.S. county warning area, is an important situation to monitor as subsequent convection may move into a forecaster’s region of responsibility.
Historical Overview of Severe Convective Storms Research
Authors: Doswell III Charles A.
Published: July 2022

An overview of the history of research related to severe convective storms is presented, with a particular emphasis on the connection between this research and forecasting. Forecasting and basic research in severe convective storms have been intertwined since the very beginnings modern severe convective storms research – that is, since the end of World War II. There are good reasons for this interaction, clearly tied to the large societal impact such storms can have. Several major milestones in severe convective storms research and key field observation campaigns are reviewed and described in terms of the interaction between observations, tools, and models that was first suggested by Tor Bergeron. This interaction continues to the present, and continues to be a useful way to understand how progress in scientific understanding about severe convective storms is developed.
Total Lightning Observations of Supercells over North Central Texas

Published: July 2022

s part of a collaborative research project between Texas A&M; University and the NOAA/NWS Fort Worth/Dallas Weather Forecast Office, total lightning observations from Vaisala’s Dallas-Fort Worth (DFW) Lightning Detection and Ranging (LDAR II) network have been used to supplement Doppler radar measurements in the diagnosis of thunderstorm updraft strength and analysis of severe weather potential.  More specifically, initial observations of severe convection over north-central Texas for three case dates have shown that total lightning flash extent density (FED) and gridded source density peaked prior to, or increased during reported severe weather events.  Two lightning holes were observed with one supercell, and numerous FED notches were noted with other cells that likely indicated the updraft region of the thunderstorms.  These signatures in the FED corresponded to weak echo regions on the KFWS WSR-88D radar reflectivity data.  Additionally, lightning appendages developed for both right- and left- deviant cells prior to shifts in radar-inferred cell track, indicating a possible method for prediction of right or left hand deflections in supercell motion.  A cell embedded within a linear MCS also developed a large notch in the FED data on its rear flank that persisted for over 25 min and preceded a severe wind report, indicating another potential forecasting application of total lightning data.
Long-Lived Tornadic Supercell over Colorado and Wyoming, 22 May 2008
Authors: Finch Jonathan D. , Bikos Daniel
Published: July 2022

On 22 May 2008, a slow-moving, meridional trough led to widespread severe weather across the Great Plains, Front Range Urban Corridor of Colorado and Laramie Mountains of Wyoming. The most damaging storm developed near the Denver International Airport and quickly became tornadic. A large tornado occurred with this storm that was responsible for EF3 damage in the town of Windsor, CO. After some weakening, the storm intensified and produced large hail and at least one tornado from the Wyoming-Colorado border northwestward to Laramie, WY. As the storm moved through differing elevations (4700 to 8700 ft (1430 to 2650 m), it also encountered markedly different meteorological environments, making this tornadic event particularly interesting and rare. In addition to the official Storm Data, this study will provide supplementary storm documentation based on accounts of local residents. The key synoptic and mesoscale features as well as shear and instability parameters are presented, with an emphasis on observational data.

Additionally, in order for forecasters to gain an understanding of the high-elevation severe storm environment, a comparison is made with relatively low-elevation environments. The importance of assessing the contributing factors to equivalent potential temperature is demonstrated. Recommendations are made for forecasting severe weather at high-elevation locations. Analysis of equivalent potential temperature is critical when assessing surface data over high-elevation areas, rather than arbitrary judgment (i.e., “it’s too cold”) based on surface temperature and dewpoint.
On the use of areal coverage of parameters favorable for severe weather to discriminate major outbreaks
Authors: Schafer Chad M. , Doswell III Charles A. , Leslie Lance M. , Richman Michael B.
Published: July 2022

Forecaster perceptions of major convective outbreaks include the notion that these events occur within relatively large regions of meteorological conditions favorable for the development of significant severe weather, particularly tornadoes. With recent studies developing a rigorous and scientifically repeatable method of identifying these events and distinguishing them from intermediate or marginal severe weather outbreaks, the investigation of a large sample of these events now is possible. This diagnostic study aims to determine the extent to which the use of areal coverage is successful as a means of discriminating major severe weather outbreaks (primarily but not exclusively major tornado outbreaks) from the less significant outbreaks. Preliminary findings suggest that the areal coverage of severe weather parameters favorable for severe weather indeed is associated with the severity of outbreaks. However, the method produces a substantial number of less significant outbreaks that are misclassified as major severe weather outbreaks. Many of these false alarms can be identified by the presence of synoptic environments that are less favorable for the development of a large number of tornadoes. However, a substantial number of intermediate and marginal severe weather outbreaks feature synoptic patterns and mesoscale environments that are difficult to differentiate from the major events. Limitations of using areal coverage as a means of outbreak discrimination are discussed, and refinements to account for these limitations are proposed.

The occurrence of giant hail, defined as hail ≥102 mm (4.00 in) in diameter, is a relatively rare phenomenon, accounting for less than 1% of all hail reports in the United States.  Despite the infrequent nature of these events, hail of this magnitude has the potential to cause extreme damage to property and a substantial threat to exposed life.  The short-term prediction of these events has been challenging.  For giant hail since 2005, only 7% of convective warnings and severe-weather statements issued by the National Weather Service (NWS) accurately predicted a maximum hail size ≥102 mm prior to the report, with an average underestimated size error of 55.6 mm (2.19 in).

The objectives of this study are to determine the detectability of giant hail in convective storms and to improve advanced recognition of these events during NWS warning operations.  A total of 568 giant-hail reports, gathered over a 15-y period from 1 January 1995 through 31 December 2009 throughout the contiguous United States, served as the primary database for the research. Weather Surveillance Radar-1988 Doppler (WSR-88D) data and North American Regional Reanalysis (NARR) environmental data were collected for each case.  Several radar signatures were examined to assess their utility in discriminating storms most favorable for giant hail.  It was found that 99% of the storms were supercells with well-organized structure.  Giant-hail producing storms were characterized by median values of rotational velocities of 24 m s-1 (47 kt), storm-top divergence magnitudes of 72 m s-1 (140 kt), and 50-dBZ and 60-dBZ echo heights of 13 100 m (43 000 ft) and 10 600 m (34 800 ft) respectively.  Vertically integrated liquid water (VIL)-based products, maximum reflectivity within the storm, and reflectivity within the preferred hail-growth zone showed little to no skill in discriminating between giant hail and smaller hail sizes.
Study of Synoptic-Scale Tornado Regimes
Authors: Garner Jonathan M.
Published: July 2022

The significant tornado parameter (STP) has been used by severe-thunderstorm forecasters since 2003 to identify environments favoring development of strong to violent tornadoes. The STP and its individual components of mixed-layer (ML) CAPE, 0-6-km bulk wind difference (BWD), 0-1-km storm-relative helicity (SRH), and ML lifted condensation level (LCL) have been calculated here using archived surface objective analysis data, and then examined during the period 2003-2010 over the central and eastern United States. These components then were compared and contrasted in order to distinguish between environmental characteristics analyzed for three different synoptic-cyclone regimes that produced significantly tornadic supercells: cold fronts, warm fronts, and drylines. Results show that MLCAPE contributes strongly to the dryline significant-tornado environment, while it was less pronounced in cold-frontal significant-tornado regimes. The 0-6-km BWD was found to contribute equally to all three significant tornado regimes, while 0-1-km SRH more strongly contributed to the cold-frontal significant-tornado environment than for the warm-frontal and dryline regimes.
Would “Tornado-Preventing” Walls Work?
Authors: Coffer Brice E.
Published: July 2022

Simulations were performed using the Weather Research and Forecasting model in order to evaluate a proposal that called for the construction of three east–west “great walls” in the American Midwest to eliminate the major threat of tornadoes in Tornado Alley. The results of three simulations using the 31 May 2013 tornado outbreak are presented—one with natural terrain, one with 300-m tall walls as proposed, and another with walls much taller than proposed (2500 m). Through comparisons of temperature, moisture, instability, and supercell and tornado composite forecasting parameters, the “tornado-preventing” walls, as proposed, are shown to have very little impact on the atmosphere. When the height of the walls is greatly increased, the location of convective storms shifts eastward, instead of being eliminated. The short-term impacts of the taller walls imply possible desertification and areas with increased probability of non-supercellular tornadoes near the edges of the walls.

The aim of this study is to investigate the relationship between cyber bullying and social media attitudes of Faculty of Communication Sciences students. At the same time, it was investigated whether students' cyberbullying attitudes and social media attitudes differ according to demographic variables. The sample of the study consists of 231 students studying at Anadolu University Faculty of Communication Sciences in 2018-2019 academic year. 117 (50.6%) of the participants were female students and 114 (49.4%) were male students. Relational survey model was used as the research model. Personal Information Form, Cyber Bullying Attitude Scale and Social Media Attitude Scale were used as data collection tools. According to the results of the research, there was a negative relationship between cyber bullying attitudes and social media attitudes of the students. There were positive and negative relationships between cyber bullying sub-dimensions and social media sub-dimensions. There was a significant difference between cyberbullying attitude and gender, frequency of social media use. A significant difference was found between social media attitude and frequency of daily internet usage and frequency of daily social media usage.

Este estudio aporta un análisis del comportamiento social de los estudiantes, entendiéndolo como un proceso dinámico en el que las acciones de cada persona son el resultado de la interacción entre contexto y comportamiento individual, destacando la agencia y el poder transformador de un individuo dentro de una comunidad.
“Soc massa bo”: Pràctiques plurilingües i de pluriliteracitat empoderadores en un programa extraescolar
Authors: Vallejo Rubinstein Claudia
Published: July 2022

En aquest article, descric les interaccions d’en Dalil, un nen plurilingüe d’origen familiar immigrant, mentre participa en un programa extraescolar de lectura a Barcelona, ​​ciutat on viu i ha estat escolaritzat. El programa s’adreça ​​​​a infants categoritzats com a ‘en risc’ de fracàs escolar per no assolir els nivells establerts de lectura en català, la llengua vehicular de l’escola, i té com a objectiu desenvolupar competències de literacitat. L'observació etnogràfica de les interaccions d’en Dalil amb companys i mentores dins del programa posa en relleu pràctiques lingüístiques i de pluriliteracitat complexes que desafien categoritzacions deficitàries sobre les seves capacitats. Analitzar aquestes pràctiques promou una comprensió més àmplia de les competències lingüístiques i de literacitat d’infants plurilingües com en Dalil, i la promoció d’enfocaments inclusius i competencials que els confereixin la legitimació –pròpia, aliena i institucional- per aprendre desplegant tot el seu repertori i múltiples competències.
