Published: July 2024

I would like to express my gratitude to Dr. Allison Wilder for her dedicated service to our profession during her tenure as Editor-in-Chief of the American Journal of Recreational Therapy (AJRT). I chose to take on the leadership role in AJRT following the retirement of Dr. Wilder, who had assumed the position after Dr. Richardson who accepted the position after the passing of Dr. Linda Buettner, the journal's founding Editor-in-Chief and a significant driving force behind its establishment.
Each of my predecessors played a pivotal role in shaping AJRT into its current form as a reputable scholarly journal for recreational therapy research and evidence-based practice information. Under their guidance, AJRT has become a sought-after resource for recreational therapists, educators, and students seeking up-to-date information on research and practice in our field. I am honored to have continued the legacy of Dr. Wilder, Dr. Buettner and Dr. Richardson, further solidifying AJRT's position in our profession.

Published: July 2024

Physical activity (PA) participation among older adults remains the lowest of any demographic, with even lower participation rates in long-term care facilities (LTCFs). While fall risk decreases when individuals engage in PA programs focused on fall prevention, enrollment in such programs remains low. The purpose of this feasibility study was to pilot questions for development of a participant survey used to explore the perceptions and motivations of older adults currently enrolled in a health promotion program called Bingocize®. The program combines fall prevention exercises with the familiar game of bingo. Study participants included a convenience sample of four older adults currently residing in a LTCF. A phenomenological qualitative research approach using video recorded interviews was chosen for the exploratory study. Results revealed that older adults viewed the overall program as enjoyable, identifying social aspects such as intergenerational connection with program facilitators as motivation for participation. Focusing attention on these factors may assist future implementation of the intervention and to promote higher levels of participation in fall prevention programs centered on PA.
Emergency preparedness in Canada: The role of recreation
Authors: Palmer, BPA CJ Luke
Published: July 2024

Emergency management has traditionally been led by an attitude to react and respond and implement effective recovery efforts. The focus has now shifted to a preparedness perspective, promoting measures which encourage the public and responders to be better equipped leading to an increased level of resiliency. Effective use of Recreation-based stakeholders and facilities, in emergency planning, boasts a number of positive elements to all phases of emergency management. A literature review will focus on the importance of Recreation in relation to preparedness. Findings will seek to articulate how the involvement of Recreation, in the realm of preparedness, builds community resilience, enhances response and recovery operations and provides a unique leadership and knowledge base regarding the use of recreational infrastructure. This effort in turn leads to a community more capable of managing an incident and returning to normalcy.

Objectives: Research suggests that ageist beliefs and behaviors have increased since the onset of the novel coronavirus 2019 (COVID-19). Considering that COVID-19 has taken a particularly heavy toll on long-term care (LTC) residents, this study examined if LTC employee perceptions of aging were influenced by working in a LTC facility during the pandemic.Methods: Qualitative data collection included 30-minute interviews with 21 LTC employees in the Boston, Massachusetts, area including 10 nurses, three nursing assistants, four clinical coordinators, two social workers, one recreation therapist, and one registered dietitian.Results: An increase in perceptions and behaviors representative of compassionate ageism (CA) was self-reported among participants.Discussion: The current study demonstrates how an increase in CA among employees was perpetuated by the COVID-19 pandemic. Allied health and nursing professionals should be mindful of attitudes toward aging, and how health events can reinforce ageist beliefs and behaviors. Opportunities for recreation therapists to lead antiageist efforts in LTC are identified.

The Positive Youth Development and Career Adaptability on Undergraduate Students: Academic Achievement Moderated
Authors: Lubis Rahmi , Amaliyana Rizki
Published: July 2024

Towards the completion of their tertiary education, students should have adapted to the work demands of the future. Career adaptability is determined by the student's character or personal assets. However, the influence of personal attributes on career adjustment is not always consistent. Other factors influence the strength of this influence. This research aims to determine the moderating role of academic achievement in the relationship between positive youth development (PYD) and student career adaptability. Data collection used the Positive Youth Development Scale and Career Adaptability Scale. We measured academic achievement using GPA. The research involved 286 eighth-semester students using a total sampling technique. Data analysis used a moderation test with Jamovi 2.0.0 statistical software. The results show that academic achievement moderates the impact of positive youth development on career adaptability. We found that PYD has a high effect on career adaptability in students with a high GPA. In contrast, PYD has low impact on career adaptability in students with low GPAs. The research results are beneficial in overcoming the low adaptability of students' careers by increasing positive youth development and academic achievement.
The Influence of Vitamin B12 on the Progression of Fracture Healing in Rats
Authors: H. P. Mana, , A. A. Mutah, , D. L. Mohzo, , W. Hermon,
Published: July 2024

Bone fracture is a complete or partial breakage of the bone structure. A bone fracture occurs when the bone structure is either completely or partially broken. The process of healing involves the regeneration of new bone tissue, which seamlessly integrates with the uninjured bone. Fracture repair entails rejoining and realigning the broken bone ends to facilitate healing. Previous reparative studies to enhance repair were limited in incorporating a therapeutically active factor to facilitate repair. Cyanocobalamin, a synthetic form of vitamin B12, is readily converted in the body into its active forms, methylcobalamin and cobamamide. In this study, 30 rats were obtained from a reputable breeder (University of Maiduguri staff quarters, line F house No. 1), acclimatized for 21 days, and divided into two groups: Group A, receiving vitamin B12 (15 rats), and Group B, serving as the control (15 rats). Group A received a dosage of vitamin B12 at 500 micrograms/kg, while Group B remained untreated. Samples from fractured tibiae were collected at two weeks intervals on days 14, 28, and 42, respectively. These samples were decalcified using formic acid, stained with Hematoxylin and Eosin (H&E), and examined under a microscope at magnifications of X10, X40, and X100. We used both qualitative and quantitative data analysis method to analyse our results. The results revealed no significant differences on day 14 both qualitatively and quantitatively. However, based on qualitative analysis, there were noticeable gross and histological disparities on days 28 and 42, although statistical analysis using Student’s t-test did not indicate significance (P>0.05) using the quantitative method. These findings suggest that vitamin B12 supplementation enhances collagen formation on days 28 and 42, potentially improving fracture repair using the qualitative data analysis method, but does not have any effect using the quantitative method.
Wrestling with the Present to Re-Imagine the Future of Social Entrepreneurship in Social Work: A South African Context
Authors: Leburu Goitseone , Skhosana Rebecca
Published: July 2024

South Africa faces many problems that require the attention of social workers. It wrestles with youth unemployment, and social work graduates are not immune to this plight. Despite the profession’s mandate of promoting social change, empowerment and liberation, the social work curriculum fails to prepare graduates for entrepreneurial opportunities. Moreover, there is a dearth of research on how the current curriculum transforms and empowers graduates to explore the untapped space of social entrepreneurship in curbing unemployment. This article utilises the Focused Mapping Review and Synthesis method to explore how unemployed social work graduates can re-imagine the future through social entrepreneurship. The review confirms that little is known on how social work graduates could apply entrepreneurship to reduce unemployment. The authors argue that the current social work curriculum must incorporate social entrepreneurship as a model for graduates to respond to the country’s unemployment crisis. This is significant since institutions of higher learning strive for transformation in developing innovative, long-term solutions to persistent social problems.

Authors: EMUDIAGA Ogheneare Mary
Published: July 2024

This study explored the influence of socio-economic characteristics on fishing practices and livelihoods in Delta State, Nigeria. The study discussed the roles of adult males, adult females, youth males, youth females and children in the study area, the constraints faced by adult males, adult females, youth males, youth females and children in fishing activities, and the significant relationship between the socio-economic characteristics of respondents and their involvement in fishing activities. The study employed descriptive research design to explore the current status of the influence of socio-economic characteristics on fishing practices and livelihoods in Delta State, Nigeria. The study was made possible by the responses obtained from 151 respondents who are artisanal fishermen/women in Delta State, Nigeria using multistage sampling technique. The researcher elicited responses from the respondents with the aid of a self-constructed open ended questionnaire, interview and a thorough review of both empirical and theoretical literature were carried out. The findings revealed that that fish sorting, salting of fish, maintenance of fish processing equipment and smoking of fish are the fish processing activities that are engaged in by the respondents. Also, artisanal fisher folks are faced with several challenges such as insufficient fish input, poor extension service, inadequate information on fishing enterprise, and lack of credit facilities. It was equally found that religion of respondents, marital status, age, income, source of credit, family size and the years of experience in fishing activities significantly determine their level of involvement in fishing activities. It was concluded that socio-economic characteristics play a pivotal role in shaping fishing practices and livelihoods in Delta State, Nigeria. Thus, it was recommended among other things that government bodies and financial institutions must collaborate to establish specialized credit facilities tailored to the needs of fishing communities

Secondary reactions of aromatics-derived oxygenated organic molecules lead to plentiful highly oxygenated organic molecules within an intraday OH exposure

Published: July 2024

Abstract. Highly oxygenated organic molecules (HOMs) can participate in new particle formation (NPF) and enhance growth of newly formed particles partially because of their low volatility. Previous studies have shown formation of HOMs via autoxidation reactions of RO2 intermediates generated by OH-initiated oxidation of anthropogenic volatile organic compounds (VOCs). It was also suggested that multi-generation OH oxidation could be an important source for aromatics-derived HOMs. However, our understanding of the generation of aromatics-derived HOMs is still insufficient, especially of their formation mechanisms, which determine molar yields of HOMs and are essential to the establishment of global chemical box models related to HOMs. In this study, with a potential aerosol mass oxidation flow reactor (PAM OFR), two series of OH-initiated oxidation experiments of 1,3,5-trimethylbenzene (1,3,5-TMB) were conducted to investigate the formation of aromatics-derived HOMs. In the first series, the evolution of oxidation products of 1,3,5-TMB in an OH exposure range of (0.5–5.0) × 1010 molecules cm−3 s, equivalent to an OH exposure of 0.7–6.9 h at an OH concentration ([OH]) of 2×106 molecules cm−3, was investigated by a nitrate-based chemical ionization mass spectrometer and a Vocus proton-transfer-reaction mass spectrometer, indicating significant secondary OH chemistry during the aging of stabilized first-generation oxygenated products within an intraday OH exposure and formation of various HOMs with lower double-bond equivalence (DBE). In addition, organonitrates, formed after the introduction of NOx into the reaction systems, further confirmed the existence of such secondary reactions. The second series of experiments was conducted with same residence time but much lower [OH], which also shows the generation of multi-generation HOMs with an [OH] as low as 1.06×107 molecules cm−3 for 53 s, i.e., an OH exposure of around 5.86×108 molecules cm−3 s. Our study suggests the important role of secondary OH chemistry in the oxidation of aromatics if these oxygenated products survived long enough in the ambient atmosphere and elucidates detailed formation mechanisms of certain HOM products.
A clustering-based method for identifying and tracking squall lines
Authors: Shi Zhao , Wen Yuxiang , He Jianxin
Published: July 2024

Abstract. The squall line is a type of convective system that is characterized by storm cells arranged in a line or band pattern and is usually associated with disastrous weather. The identification and tracking of squall lines thus play important roles in early warning systems for meteorological disasters. Here, a clustering-based identification and tracking algorithm for squall lines is presented based on weather radar data. A clustering analysis is designed to distinguish the strong echo area and estimate the feature value, including the reflectivity value, length, width, area, endpoints, central axes, and centroid. The linearly arranged clusters are merged to improve the identification of squall line development. The three-dimensional structure and movement tracking of the squall line are obtained using the centroid and velocity of the squall lines identified in each layer. The results demonstrate that the method can effectively identify and track one or more squall lines across the radar surveillance area. The results also show that the recognition accuracy rate for the single scan elevation of this method is 95.06 %, and the false-positive rate is 3.17 %. This method improves the accuracy of squall line identification in the development stage of squall lines and still works efficiently even when high interference contamination occurs.
High interspecific variability in ice nucleation activity suggests pollen ice nucleators are incidental
Authors: Kinney Nina L. H. , Hepburn Charles A. , Gibson Matthew I. , Ballesteros Daniel , Whale Thomas F.
Published: July 2024

Abstract. Ice-nucleating macromolecules (INMs) produced by plant pollen can nucleate ice at warm temperatures and may play an important role in weather- and climate-relevant cloud glaciation. INMs have also proved useful for mammalian cell and tissue model cryopreservation. The high ice nucleation (IN) activity of some INMs indicates an underlying biological function, either freezing tolerance or bioprecipitation-mediated dispersal. Here, using the largest study of pollen ice nucleation to date, we show that phylogenetic proximity, spermatophyte subdivision, primary growth biome, pollination season, primary pollination method, desiccation tolerance and native growth elevation do not account for the IN activity of INMs released from different plant species' pollen. The results suggest that these macromolecules are produced by plants for a purpose unrelated to ice nucleation and have an incidental ability to nucleate ice. This ability may have been adapted by some species for specific biological purposes, producing exceptional ice nucleators. Pollen INMs may be more active, widespread in nature, and diverse than previously thought.
AMOC stability amid tipping ice sheets: the crucial role of rate and noise
Authors: Sinet Sacha , Ashwin Peter , von der Heydt Anna S. , Dijkstra Henk A.
Published: July 2024

Abstract. The Atlantic Meridional Overturning Circulation (AMOC) has recently been categorized as a core tipping element as, under climate change, it is believed to be prone to critical transition implying drastic consequences on a planetary scale. Moreover, the AMOC is strongly coupled to polar ice sheets via meltwater fluxes. On the one hand, most studies agree on the fact that a collapse of the Greenland Ice Sheet would result in a weakening of AMOC. On the other hand, the consequences of a collapse of the West Antarctica Ice Sheet are less well understood. However, some studies suggest that meltwater originating from the Southern Hemisphere is able to stabilize the AMOC. Using a conceptual model of the AMOC and a minimal parameterization of ice sheet collapse, we investigate the origin and relevance of this stabilization effect in both the deterministic and stochastic cases. While a substantial stabilization is found in both cases, we find that rate- and noise-induced effects have substantial impact on the AMOC stability, as those imply that leaving the AMOC bistable regime is neither necessary nor sufficient for the AMOC to tip. Also, we find that rate-induced effects tend to allow a stabilization of the AMOC in cases where the peak of the West Antarctica Ice Sheet meltwater flux occurs before the peak of the Greenland Ice Sheet meltwater flux.
The Ensemble Consistency Test: From CESM to MPAS and Beyond
Authors: Price-Broncucia Teo , Baker Allison , Hammerling Dorit , Duda Michael , Morrison Rebecca
Published: July 2024

Abstract. The Ensemble Consistency Test (ECT) and its Ultra-Fast variant (UF-ECT) have become powerful tools in the development community for the identification of unwanted changes in the Community Earth System Model (CESM). By characterizing the distribution of an accepted ensemble of perturbed ultra-fast model runs, the UF-ECT is able to identify changes exceeding internal variability in expensive chaotic numerical models with reasonable computational costs. However, up until now this approach has not seen adoption by other communities, in part because the process of adopting the UF-ECT procedure to other models was not clear. In this work we develop a generalized setup framework for applying the UF-ECT to different models and show how our specification of UF-ECT parameters allow us to balance important goals like test sensitivity and computational cost. Finally, we walk through the setup framework in detail and demonstrate the performance of the UF-ECT with our new determined parameters for the Model Across Prediction Scales-Atmosphere (MPAS-A) model, the substantially updated CESM atmospheric model, and realistic development scenarios.
Exploring factors affecting route choice of cyclists: A novel varying-contiguity spatially lagged exogenous modeling approach
Authors: Van Nijen Nick , Ulak M. Baran , Veenstra Sander , Geurs Karst
Published: July 2024

Cycling is one of the main transport modes and cycling infrastructure is strongly embedded in transport infrastructure in the Netherlands. Nonetheless, the bicycle network still undergoes frequent improvements and expansions. One of the critical elements in deciding on improvements and expansions is to understand the route choice of cyclists, which helps identify bottlenecks in bicycle flows and substantiate the need for new bicycle infrastructure. Yet, the factors affecting the route choice of cyclists are still not fully understood. To address this, we develop a varying-contiguity spatially lagged exogenous (VCSLX) model and analyze the probability of a cyclist choosing a certain segment based not only on the characteristics of that segment but also considering the characteristics of its neighbors along a route. Characteristics that are included in this study are the presence of bicycle infrastructure, traffic control installations and artificial lighting, as well as pavement type, bicycle and motorized-vehicle volumes and different land-use zones. The model involves the analysis of the observed routes extracted from cycling trajectories from Fietstelweek data, as well as corresponding hypothetical shortest path routes identified from the origin-destinations of the observed trips and the cycling network. The results of the study can help to understand the factors convincing cyclists to deviate from the shortest possible routes. The study contributes to the current literature by focusing on the underexplored aspect of spatial dependencies between route segments in the route choice of cyclists.

Effects of a Manual Treatment on Lumbar Microcirculation and Tissue Stiffness Following Submaximal Eccentric Trunk Extensor Exercise: A Randomized Controlled Trial
Authors: Brandl Andreas , Keiner Michael , Wilke Jan , Egner Christoph , Schleip Robert , Schmidt Tobias
Published: July 2024

Recent studies have shown that the extramuscular connective tissue (ECT) is thickened and stiffened in delayed onset muscle soreness (DOMS). However, contrarily to the normal population, severe DOMS is rare in athletes or highly trained individuals. The present randomized, controlled trial therefore aimed to investigate pain as well as microcirculation and stiffness of the ECT and the erector spinae muscle following submaximal eccentric trunk extension exercise not causing DOMS. The effect of manual treatment by a therapist (myofascial release; MFR) on these parameters was to be studied. Trained healthy participants (n = 21; 31.3 ± 9.6 years; > 4 h exercise per week) performed submaximal eccentric exercise of the trunk extensors. One group was manually treated (n = 11), while the other group (n = 10) received placebo treatment with sham laser therapy. Stiffness of the ECT and the erector spinae muscle (shear wave elastography), microcirculation (white light and laser Doppler spectroscopy), palpation pain (100 mm visual analogue scale, VAS) and pressure pain threshold (indentometry, PPT) were assessed before (t0), 24 h (t24) and 48 h (t48) after conditions. Erector spinae muscle stiffness increased after eccentric exercise from t0 to t24 (0.875 m/s) and from t0 to t48 (0.869 m/s). After MFR, erector spinae muscle stiffness decreased in contrast to placebo treatment at t24 (-0.66 m/s), while ECT stiffness remained unchanged. Oxygen saturation increased (17-20.93%) and relative haemoglobin decreased (-9.1 - -12.76 AU) after eccentric exercise and MFR differed from placebo treatment at t48 (-3.71 AU). PPT differed after MFR from placebo treatment at t48 (20.69 N/mm), while VAS remained unchanged. Multiple linear regression showed that ECT stiffness and group membership predicted erector spinae muscle stiffness. MFR could have a positive effect on pain, microcirculation and muscle stiffness after submaximal eccentric exercise, suggesting better recovery, which needs to be confirmed by future work.

Economic growth—through growth affordability, growth investments, and growth-awareness associations—may lead to increased access to clean fuel and technologies for cooking (ACF&T). The current paper presents the trend and comparative analyses regarding GDP per capita, access to clean fuels and technologies for cooking, and renewable energy consumption (REC) in the South Asian economies. The data from Bangladesh, India, and Pakistan between 2000 and 2020 shows a strong positive correlation between GDP per capita and access to clean cooking technologies. India has made the most significant improvements, followed by Pakistan and Bangladesh. All three economies negatively correlate GDP per capita and renewable energy consumption. Bangladesh shows the steepest decline, followed by India and Pakistan, indicating a more pronounced shift towards nonrenewable energy sources as economic prosperity increases. The study concludes that economic development often involves transitioning from traditional renewable energy sources (such as biomass) to more modern, nonrenewable energy sources (such as fossil fuels), often more efficient and reliable for industrial and large-scale energy needs. Hence, developing infrastructure and industrial sectors might lead to higher consumption of nonrenewable energy sources. This points to a potential challenge for sustainable development, as increased economic prosperity might be accompanied by more significant environmental impact unless there are concerted efforts to promote renewable energy sources.
A Study on the Characteristics of Educational Governance and Education Policy of the Yoon Suk Yeol Government
Authors: Kim Yong-il
Published: July 2024

This study aims to analyze the characteristics of educational governance and education policy of Yoon Suk Yeol Government(Yoon Government). As an educational governance is a form or foundation of policy contents, first of all, the author focuses on the educational governance of Yoon Government. And then, analyzing main policies of Yoon Government, the author try to reveal the dialectical relations of educational governance and education policy. The results of this study are as follows.
Firstly it is found that “Ministry of Education-led educational governance” (‘MOE-led governance’) is established by the complex condition of Education Commission sailing, buoying conservative superintendents, and the appointment problem of Minister of Education in addition to regime change. Secondly the author finds that while the education policy of Yoon Government is get into stride after inauguration of Minister Lee Ju Ho, it is characterised by the full-fledged “new privatization education policy” which is took a step forward than neo-liberal education policy. Thirdly the author recognizes that MOE-led governance is the essential or prerequisite element of new privatization education policy of Yoon Government.
An Analysis of the Relation between Changes in High School Institution and Political Elite Recruitment: Focusing on Candidates for 22nd Congressmen in Two Major Parties
Authors: Kim Seung Ho , Jang Soo Myung
Published: July 2024

This study investigate how high schools that candidates for 22nd congressmen had attended have changed according to changes in high school institution, assuming the high school connections are important in political elite recruitment. We divided three periods, before high school equalization policy(HSEP), after HSEP , after introduction of special-purpose high school policy(SPHSP). We analyze how these different high school institutions affect political elite recruitment. The result indicates that HSEP have made political elites from more diverse schools and also suggested the possibility that political representation more wide and inclusive. In other aspect, HSEP also made private high school graduates become more political elite, which can imply that private schools with intense school identity with the same teaching staff and stable leadership more actively organize students’ school lives. After SPHSP, political elites are recruited more from SPH, which can disturb reversely democratic diversity in political elite representation. This study shows that HSEP have made political representation diverse and indirectly implies its importance in democratic politics. High school institution can not only be judged in terms of excellence and equality but also it should be treated in terms of its political implications.
An Overview of Humus state in reclaimed lands, Bulgaria. Bulgarian experience in Wales, UK
Authors: Filcheva Ekaterina
Published: July 2024

Soil forming process is accompanied by the accumulation of organic matter. Soil organic matter is an important component of soil physical characteristics, physico-chemical characteristics, formation of organo-mineral complexes for natural soils and determines soil fertility. All over the world large territories are disturbed after open-cast and underground coal mining processes demand biological land reclamation. Worldwide, forestation with different tree species and grasses are well known approaches and practices. Knowledge and experience on soil forming processes and humus formation in the initial stage clarify the direction and intensity of these important processes in land reclamation. Content of organic carbon and organic matter composition for different test plots of reclaimed lands in “Maritsa Iztok” JSCo and Pernik coal basin is discussed. Information on the land reclamation with zeolite materials in “Maritsa Iztok” JSCo is presented. Data on the Bulgarian experience of afforestation in Wales, UK is described.
Organic petrology as a tool for peat-forming environmental reconstructions: insights from Suhostrel and Bobov Dol coals, SW Bulgaria

Published: July 2024

The petrographic composition of samples from Suhostrel and Bobov Dol coal deposits was studied using optical micro­scopy. The maceral contents were further used to calculate maceral ratios which were interpreted in terms of environmental condition during peat deposition. Petrographic data of Suhostrel coal is compatible with its organic geochemical characteristics and indicate peat formation under inundated topogenous, meso- to rheotropic, sparsely forested marsh- or fen-type environment. Coal facies diagrams for Bobov Dol coal, however, provide contradictory depositional settings and therefore cannot be used alone for environmental reconstruction.
Mineralogical characteristics of coal seams Ia, I and IIa from Bobov Dol Basin, SW Bulgaria
Authors: Zdravkov Alexander , Yovchev Danail
Published: July 2024

The mineralogical composition of Bobov Dol sub-bituminous coals from the lower part of the coal-bearing formation, was studied using optical microscopy, XRD and SEM-EDS analyses. Clay minerals (smectite, illite and kaolinite) and quartz, are the dominant minerals. Their characteristics indicate predominant terrigenous origin and argue for major detrital input from intermediate to mafic rocks. Accessory epigenetic barite-celestine mineralization, substituting almost completely oxidized siderite crystals and spheroidal aggregates, denotes circulation of meteoric aqueous solutions in the absence of other fracture-filing minerals. Finite glass spheres from the top of the coal seam I indicate synchronous volcanic activity, which did not influence peat formation.
Investigating Effects of Age on Sequential Syntactic and Morphological Development in Pakistani Second Language Learners

Published: July 2024

Learning a second language, primary-level students find the process of developing syntax complex perhaps because they do not have sufficient awareness of the syntactic errors they commit at this early stage. Yet, there is a scarcity of studies on this domain to the best of our knowledge. Employing a mixed-method approach, the current study used tests, interviews, and observations to investigate the complexity of the developmental sequences with a particular emphasis on syntactic errors made by Pakistani learners of ESL. Analyzing the data quantitatively and qualitatively, the study caters to the common syntactic errors committed by Pakistani primary school students, including tense, subject-verb agreement, missing articles, conjunction, pronouns to infinitives, and word order. The study concluded that the sequential syntactic development in acquiring syntax is highly influenced by the factor of age perhaps because older children acquire syntax faster than younger ones. The study implicates to development of the second language at the primary level with a diverse age range.
Naturalismo en La Ciénaga: apuntes para pensar el rol del cuerpo en el cine de sensaciones de Lucrecia Martel
Authors: Podhorzer Nicolás
Published: July 2024

El presente artículo se propone ofrecer una mirada problemática sobre el naturalismo en La Ciénaga (2001) de Lucreica Martel tomando la experiencia del cuerpo como hilo conductor. Nuestra hipótesis principal tiene dos caras: en primer lugar, la experiencia del cuerpo en La Ciénaga resulta inescindible de un tratamiento del sonido, el cual cumple un rol preponderante respecto a la imagen, y que se puede expresar en lo que Kratje conceptualizó como atmósferas generizadas (2019); en segundo lugar, para dar cuenta cabalmente de la singularidad de cada cuerpo y del problema de su heterocronía según sus rasgos sociales, es preciso presentar cierto bergsonismo usualmente soslayado en Martel, que se expresa en una comunidad de problemas con el filósofo francés más que en una afinidad conceptual. Creemos, en ese sentido, que la interpretación del naturalismo ofrecida por Gilles Deleuze en La imagen-movimiento (2013) solo comprende parcialmente la especificidad de La Ciénaga, y que el diseño del sonido presenta una estructura de pensamiento autónoma que requiere de mayor precisión conceptual. No obstante, el contraste con sus categorías permitirá comprender en qué medida la experiencia del cuerpo propuesta por el cine de sensaciones de Martel logra salirse de este esquema naturalista.
