Navigational Experiences of Five Mexican Immigrant Mothers in U.S. Schools: Introducing Communal Capital
Authors: Yrigollen-Robbins Michelle 
Published: March 2024

This qualitative study highlights the experiences of how five Latina immigrant mothers use their community cultural wealth (CCW) to settle in metro Atlanta. Data was generated over 3 years through semi-structured interviews. The participants’ testimonios collected from the interviews were deductively analyzed apriori by focusing on evidence of the six proposed elements of CCW revealed in their immigration stories. I found these women not only used the six components of CCW but also used what I term “communal capital”—the reliance on neighbors as cultivated through their relationships with strangers who lived in the same residential (apartment) dwellings. This study highlights the theory of communal capital as a tool that suggests how to research Latino immigrant communities in the United States.

Published: March 2024

In this paper, solar cells with ZnO electrode modified with Al2O3, were manufactured and characterized, through the sol gel process: the precursor used was Zinc Nitrate hexahydrate (Zn (NO3)2.6H2O) [0.1 M] and triethalonamine (TEA) [0.1M] was added with a heat treatment (100 °C) and later by precipitation, the ZnO nanoparticles were obtained. They were then sensitized with the N719. The paste used to obtain the ZnO film is modified with Al2O3 in different percentages. This modification is achieved when the precursor (Al (NO3)3.9H2O) is added to the aqueous suspension of ZnO. For this procedure the following characterizations were made: (1) XRD to check the crystal lattice of ZnO; (2) SEM to observe the rod-like morphology of the sample and with an average grain size of 90 nm, the nanoporosity of the samples was also observed; (3) UV Vis to check the absorption spectrum of the dye that is in the visible region; (4) EDS to check the presence of Aluminium and Zinc, (5) IV to determine the efficiency of the cell (0.39%); (6) OCVD to determine electron life time as a function of voltage; (7) IPCE to measure quantum efficiency (maximum 13%); (8) FTIR to identify and verify the existence of functional groups in the cell; (9) EIS that allows the determination of the parameters: electron half-life, electron transport time, resistance of the ZnO/dye/electrolyte interface, resistance of the film capacitive behaviour of the cell, which are important data that allow knowing the chemical and electrochemical processes of the cells.

Published: March 2024

The work presents an examination of Poland's environmental condition, with a focus on the contamination of air and surface waters by various chemical elements. The composition and quality of the air impact ecosystems, plant growth, the animal kingdom, and shape human living conditions. These factors play a significant role in driving global climate change. The repercussions of air pollution encompass phenomena such as smog, acid rain, ozone layer depletion, as well as impacts on industrial and municipal facilities, contributing to global warming. The article conducts an analysis of air pollution, surface water contamination, and electromagnetic radiation pollution in Subcarpathian, utilizing the city of Stalowa Wola and the Stalowa Wola county as case studies. This choice is informed by the fact that Stalowa Wola stands as one of the largest industrial cities in the Subcarpathian Voivodeship, suggesting that environmental pollution levels in this county might surpass those in other regions. The article also delineates the features of air and surface water pollution, along with electromagnetic radiation characteristics. It scrutinizes pollution sources in the mentioned county, explicates the causes of such pollution, and proposes strategies for environmental amelioration. The analysis of the environmental status of Stalowa Wola county during the years 2018 to 2020 is presented, accompanied by recommendations for initiatives that could enhance its condition. The research findings indicate that the condition of uniform segments of surface waters, as evaluated through conducted studies, is deemed poor. The discharge of wastewater from specific pollution points, particularly wastewater from municipal origins, emerges as the predominant cause of subpar water quality.

Published: March 2024

Aims: The advancement and integration of technology in education made a dramatic change in the landscape of the teaching-learning process. Massive Open Online Courses (MOOCs) as one of the emerging trends in education removed the barriers of time, space, and pace throughout the world. Diverse lifelong learners irrespective of social, cultural, economic, age and gender identity are participating in the melting pot of MOOC. This study aimed to explore the present landscape of the participation and completion rate in MOOCs by learners from formal educational institutions in the eastern part of India specifically in West Bengal. The research also aimed to identify the underlying causes of the present landscape.
Place and Duration of Study: The study was conducted among the learners who enrolled in different programs in different Higher Education Institutions (HEIs) during the end of 2023.
Methodology: A self-administered questionnaire in Google Forms was used to collect data from the learners. A total 298 samples have been collected. Collected data have been analyzed by descriptive statistics, independent samples ‘t’ test, ANOVA using SPSS and MS Excel.
Results: The study depicted poor enrolment as well as completion rates in MOOCs among the learners. Lack of awareness and huge pressure on the present curriculum were the main factors behind non-enrolment. SWAYAM was the most popular MOOC platform among the students of West Bengal. Attaining knowledge, enhancing skills, and earning certificates were the main intentions of the students who enrolled in MOOCs. Lack of time, affordability, in-person proctored examination, non-cooperation of facilitators, length of courses, and uninteresting discussion forum were the major constraints to completing the MOOCs for the enrolled learners.
Conclusion: Organizing awareness-building programs, institutional policy framing, and incorporating a credit transfer system into enrolled courses may be emphasized as immediate initiatives for re-thinking the present opportunities and challenges in higher education.
