Walking the story of my Indo-Mauritian indentured ancestry: An arts-based inquiry into voiced resistance and conflict with reconciliation

Reconciliation is a contested term often associated with postcolonial discourses, contending with global histories of injustice, racial discrimination and dispossession that affect diverse groups (slaves, indentures or Indigenous people). Reconciliation stories mainly encounter resistance when problematized by individual experiences. As a woman of Indo-Mauritian indenture descent, I explore my ancestral stories from gendered dimensions: hailed by hardships, discrimination and patriarchal norms from colonialization and its legacies. I discuss my perceived subalternity and disempowerment in defining my positioning and identity. From an arts-based inquiry, I use bricolage to combine art·I/f/act·ology, evocative auto-ethnography and emotional reflexivity in framing emotion-based writing. Intersectionality as a theoretical lens situates the influences of race, culture, ethnicity, caste, gender and identity processes within my narratives. The discussion emphasizes a voiced resistance and conflict with reconciliation. My visual narratives display and are rooted in the listening and co-ownership of ancestral stories as mine, wherein I find voice and agency.

Intercultural Dialogues in Third Spaces: A Study of Learning Experiences of Museum Visitors

Bodo (2012) called for the need of museum exhibitions to create “third spaces” where individuals can cross the boundaries of belonging (both physical and psychological) to engage in intercultural dialogues. The imaginary cultural space of museum has propelled us into a realization that we are in an era where interculturality, transculturalism, and the eventual prospect of identifying a cosmopolitan citizenship can become a reality. Predicated on a five-month ethnography work at a provincial museum in British Columbia, Canada, this research explores the following questions: how have cultural and historical museum exhibitions put us in contact with the other and foster an understanding of the other? And how has transculturalism led to the establishment of a cosmopolitan citizenship? This study lends support to the potentiality of a cultural and historical museum transforming into “third spaces” where visitors may actively engage in exploration of complex multitudes of cultural identities and cosmopolitan citizenship. The findings of this study contribute to the literature on “third spaces” and transculturalism by providing an empirical study of learning experiences of visitors in museums. It reaffirms the notion of transculturalism by proposing a new humanism in recognition of the other, and in expressing oneself in a conscious subjective manner with cultural empathy. From a practical perspective, it suggests that in order to encourage international visitors to cross the cultural and psychological boundaries and engage in dialogues, the museum professionals may design interactive programs in a creative manner. It also suggests that museum administrators improve their services to more diverse groups of visitors to enhance inclusiveness.

Contrasting Community Assembly Mechanisms Underlie Similar Biogeographic Patterns of Surface Microbiota in the Tropical North Pacific Ocean

Bacteria and microeukaryotes are extremely diverse groups in the ocean, where they regulate elemental cycling and energy flow. Studies of marine microbial ecology have benefited greatly from the rapid progress that has been made in genomic sequencing and theoretical microbial ecology.

Case Study: Partnering Intercultural Communication Students with Campus Co-Cultural Student Groups to Develop Intercultural Competence, Allyship, and Curiosity

The question I analyze in this case study is how might one use civic engagement to foster campus/community relationships in this polarized era? I describe a teaching challenge in intercultural communication. Students have consistently reported that they arrive to this university from rural, majority-White communities where they have not experienced opportunities to communicate with culturally diverse groups. To address this challenge, I developed a semester-long assignment that provides a structured partnership between students in my Intercultural Communication course and campus co-cultural student groups. To assess this assignment’s benefit to the pedagogy surrounding polarization across cultural differences, I qualitatively analyzed themes in students’ reflection papers (N = 128 papers) from the last five sections of the course (2016–2020). Students addressed how these partnerships helped them develop (1) intercultural competence, (2) acceptance or appreciation through allyship, and (3) curiosity about other cultures. I conclude with implications, including how colleagues might use this assignment in other rural, land-grant public university settings.

Phytoplankton Biodiversity in Two Tropical, High Mountain Lakes in Central Mexico

Lakes El Sol and La Luna, inside the crater of the Nevado de Toluca volcano, Central Mexico, are the only two perennial high mountain lakes [HML] in the country. HML are considered among the most comparable ecosystems worldwide. These lakes are “extreme” environments with diluted, oligotrophic, and cold waters exposed to high UV radiation doses. In this paper, we document the phytoplankton species inhabiting these two extreme tropical ecosystems. The phytoplankton diversity of Lakes El Sol and La Luna is low compared to the global phytoplankton diversity from other Mexican inland waters. Nonetheless, the phytoplankton diversity turned out to be high compared to other HML worldwide, both temperate and tropical. The phytoplankton community in Lake El Sol was formed by 92 morphospecies and in Lake La Luna by 63; in both, the most diverse groups were Bacillariophyceae and Chlorophyceae. All species found in Lake La Luna were present in Lake El Sol, but 29 species present in Lake El Sol were absent in Lake La Luna. Nevertheless, 57% of the most frequent and abundant taxa in Lake El Sol were rare in La Luna, and 47% of the most frequent and abundant taxa in Lake La Luna were rare in Lake El Sol. Associated with their shallowness and polymictic thermal pattern, 87.5% of the Bacillariophyceae morphospecies are tychoplantonic, while the remaining 12.5% are truly planktonic. Dominant taxa were Chlorophyceae in Lake El Sol and Cyanobacteria in Lake La Luna. The most extreme conditions of Lake La Luna (ultraoligotrophy, very low pH, high ultraviolet radiation) most likely explained the differences in the dominant species composition and lower species richness compared to Lake El Sol. Herein, we provide for the first time a taxonomic list of the phytoplankton community of Lakes El Sol and La Luna. This information constitutes a baseline needed to use these HML as sentinels of global and climate change.

Defense in Social Insects: Diversity, Division of Labor, and Evolution

All social insects defend their colony from predators, parasites, and pathogens. In Oster and Wilson's classic work, they posed one of the key paradoxes about defense in social insects: Given the universal necessity of defense, why then is there so much diversity in mechanisms? Ecological factors undoubtedly are important: Predation and usurpation have imposed strong selection on eusocial insects, and active defense by colonies is a ubiquitous feature of all social insects. The description of diverse insect groups with castes of sterile workers whose main duty is defense has broadened the purview of social evolution in insects, in particular with respect to caste and behavior. Defense is one of the central axes along which we can begin to organize and understand sociality in insects. With the establishment of social insect models such as the honey bee, new discoveries are emerging regarding the endocrine, neural, and gene regulatory mechanisms underlying defense in social insects. The mechanisms underlying morphological and behavioral defense traits may be shared across diverse groups, providing opportunities for identifying both conserved and novel mechanisms at work. Emerging themes highlight the context dependency of and interaction between factors that regulate defense in social insects.

Indirect Routes to Aminoacyl-tRNA: The Diversity of Prokaryotic Cysteine Encoding Systems

Universally present aminoacyl-tRNA synthetases (aaRSs) stringently recognize their cognate tRNAs and acylate them with one of the proteinogenic amino acids. However, some organisms possess aaRSs that deviate from the accurate translation of the genetic code and exhibit relaxed specificity toward their tRNA and/or amino acid substrates. Typically, these aaRSs are part of an indirect pathway in which multiple enzymes participate in the formation of the correct aminoacyl-tRNA product. The indirect cysteine (Cys)-tRNA pathway, originally thought to be restricted to methanogenic archaea, uses the unique O-phosphoseryl-tRNA synthetase (SepRS), which acylates the non-proteinogenic amino acid O-phosphoserine (Sep) onto tRNACys. Together with Sep-tRNA:Cys-tRNA synthase (SepCysS) and the adapter protein SepCysE, SepRS forms a transsulfursome complex responsible for shuttling Sep-tRNACys to SepCysS for conversion of the tRNA-bound Sep to Cys. Here, we report a comprehensive bioinformatic analysis of the diversity of indirect Cys encoding systems. These systems are present in more diverse groups of bacteria and archaea than previously known. Given the occurrence and distribution of some genes consistently flanking SepRS, it is likely that this gene was part of an ancient operon that suffered a gradual loss of its original components. Newly identified bacterial SepRS sequences strengthen the suggestion that this lineage of enzymes may not rely on the m1G37 identity determinant in tRNA. Some bacterial SepRSs possess an N-terminal fusion resembling a threonyl-tRNA synthetase editing domain, which interestingly is frequently observed in the vicinity of archaeal SepCysS genes. We also found several highly degenerate SepRS genes that likely have altered amino acid specificity. Cross-analysis of selenocysteine (Sec)-utilizing traits confirmed the co-occurrence of SepCysE and the Sec-utilizing machinery in archaea, but also identified an unusual O-phosphoseryl-tRNASec kinase fusion with an archaeal Sec elongation factor in some lineages, where it may serve in place of SepCysE to prevent crosstalk between the two minor aminoacylation systems. These results shed new light on the variations in SepRS and SepCysS enzymes that may reflect adaptation to lifestyle and habitat, and provide new information on the evolution of the genetic code.

Crowdsourced Knowledge in Organizational Decision Making

Inefficiencies naturally form as organizations grow in size and complexity. The knowledge required to address these inefficiencies is often stove-piped across different organizational silos, geographic locations, and professional disciplines. Crowdsourcing provides a way to tap into the knowledge and experiences of diverse groups of people to rapidly identify and more effectively solve inefficiencies. We developed a prototype crowdsourcing system based on design thinking practices to allow employees to build a shared mental model and work collaboratively to identify, characterize, and rank inefficiencies, as well as to develop possible solutions. We conducted a study to assess how presenting crowdsourced knowledge (votes/preferences, supporting argumentation, etc.) from employees affected organizational Decision Makers (DMs). In spite of predictions that crowdsourced knowledge would influence their decisions, presenting this knowledge to DMs had no significant effect on their voting for various solutions. We found significant differences in the mental models of employees and DMs. We offer various explanations for this behavior based on rhetorical analysis and other survey responses from DMs and contributors. We further discuss different theoretical explanations, including the effects of various biases and decision inertia, and potential issues with the types of knowledge elicited and presented to DMs.

Redesigning GE Language

This case study delineates changes enacted in the cultural program for beginning-level Spanish language students at a private, faith-based university. Given the restrictions of the pandemic insofar as virtual teaching and learning, as well as the national and international context of racial strife and inequities, the instructors took the opportunity to utilize antiracist pedagogy in order to reach the goals of meaningful content and measurable student outcomes. One of the General Education learning outcomes demonstrates how well students understand the “complex issues faced by diverse groups in global and/or cross-cultural contexts.” Within the context of Latin America and the Latina/Latino experience in the United States, the assignments focus on the intersections of race and gender as they relate to cultural expressions, ensuring that the approach does not obfuscate contributions nor realities of people of color.

Maintaining Ethnic Boundary: The Ethnogenesis of Madhesi Identity in Nepal Tarai

This article attempts to illuminate on the processes wherein diverse groups of Madhesi people of the central Tarai have been ethnicized to form a shared identity in the specific historical and socio-political context of Nepal. Drawing on the perceptions and subjective experiences of Madhesi individuals in terms of their identity, it is argued that Madhesi identity has come into being and maintained through the practices of boundary maintenance that encompasses relational processes of inclusion and exclusion. Madhesi people have re(asserted) their cultural contrast to the Pahadis and claim political autonomy of the Tarai territory where they belong for making ethnic distinction and maintaining group boundary.
