Transformative Learning Through Cultural Immersion

This qualitative study explored avenues to increase students’ intercultural competence through transformative learning. School of Education graduate students and faculty from a small, private university traveled to Ecuador to participate in a cultural immersion practicum. In addition to these primary goals, the trip was designed to facilitate transformative learning about cultural conceptions, diversity, and the dynamics of student differences with the goal of understanding one’s own cultural framework and adapting to another culture to develop empathy towards culturally and linguistically diverse students in the United States

\u3cem\u3eRhizobium phaseoli\u3c/em\u3e Symbiotic Mutants with Transposon Tn5 Insertions

Rhizobium phaseoli CFN42 DNA was mutated by random insertion of Tn5 from suicide plasmid pJB4JI to obtain independently arising strains that were defective in symbiosis with Phaseolus vulgaris but grew normally outside the plant. When these mutants were incubated with the plant, one did not initiate visible nodule tissue (Nod-), seven led to slow nodule development (Ndv), and two led to superficially normal early nodule development but lacked symbiotic nitrogenase activity (Sna-). The Nod- mutant lacked the large transmissible indigenous plasmid pCFN42d that has homology to Klebsiella pneumoniae nitrogenase (nif) genes. The other mutants had normal plasmid content. In the two Sna- mutants and one Ndv mutant, Tn5 had inserted into plasmid pCFN42d outside the region of nif homology. The insertions of the other Ndv mutants were apparently in the chromosome. They were not in plasmids detected on agarose gels, and, in contrast to insertions on indigenous plasmids, they were transmitted in crosses to wild-type strain CFN42 at the same frequency as auxotrophic markers and with the same enhancement of transmission by conjugation plasmid R68.45. In these Ndv mutants the Tn5 insertions were the same as or very closely linked to mutations causing the Ndv phenotype. However, in two mutants with Tn5 insertions on plasmid pCFN42d, an additional mutation on the same plasmid, rather than Tn5, was responsible for the Sna- or Ndv phenotype. When plasmid pJB4JI was transferred to two other R. phaseoli strains, analysis of symbiotic mutants was complicated by Tn5-containing deleted forms of pJB4JI that were stably maintained

Preparing Teacher Candidates to Serve Students From Diverse Backgrounds: Triggering Transformative Learning Through Short-Term Cultural Immersion

This study followed 24 teacher candidates in a short-term cultural immersion field experience designed to help them reflect on their assumptions and perspectives in order to better understand the culturally, ethnically, and linguistically diverse students they will teach. Qualitative methods were informed by a phenomenological research approach to examine candidates’ transformative learning experiences in a cultural immersion context. The findings are discussed within a three-stage framework of transformative learning: triggering experiences, frame of reference examination, and transformative change

Collegial Forms of Implementation of Directionality in National Innovation Strategies

The normative turn that occurred as a result of radical reforms in science, technology, and innovation policies in various countries has sparked a broad discussion around the “directionality-neutrality” dilemma in science, technology, and innovation (STI) development strategies. However, despite a number of recent publications and science and innovation policy programs, the relationship between these two principles, including the practice of their application by government agencies, remains understudied. A representative analysis (using qualitative methods) of the two national STI councils and their role in strategy development, focusing on the process of approach selection and its value orientation, will fill this gap. On the basis of the collected information and scientific literature, the connection with different policy options is identified. It is shown that the role of the councils is determined by their powers and resources and the boundaries of relevant practices and directions for further research are outlined

Implementation of a Remote Control and Monitoring System in Assembly Processes with Industrial Robot Kawasaki Rs003 Through the GSM Network in the Industrial Automation Laboratory of the Faculty of Mechanics

The control and monitoring of processes with industrial robot requires a means of remote communication that allows the operator to know the current state of the process in addition to sending new production parameters by means of a Programmable Logic Controller (PLC) and a compatible CP1242-7 module with the Global System for Mobile Communications (GSM), integrated into a multipurpose assembly station and based on experimentation to verify the correct functioning of the communication system through text messages.   Keywords: industrial robot, PLC, GSM, assembl

Internal Colonization of Salmonella enterica Serovar Typhimurium in Tomato Plants

Several Salmonella enterica outbreaks have been traced back to contaminated tomatoes. In this study, the internalization of S. enterica Typhimurium via tomato leaves was investigated as affected by surfactants and bacterial rdar morphotype, which was reported to be important for the environmental persistence and attachment of Salmonella to plants. Surfactants, especially Silwet L-77, promoted ingress and survival of S. enterica Typhimurium in tomato leaves. In each of two experiments, 84 tomato plants were inoculated two to four times before fruiting with GFP-labeled S. enterica Typhimurium strain MAE110 (with rdar morphotype) or MAE119 (without rdar). For each inoculation, single leaflets were dipped in 109 CFU/ml Salmonella suspension with Silwet L-77. Inoculated and adjacent leaflets were tested for Salmonella survival for 3 weeks after each inoculation. The surface and pulp of ripe fruits produced on these plants were also examined for Salmonella. Populations of both Salmonella strains in inoculated leaflets decreased during 2 weeks after inoculation but remained unchanged (at about 104 CFU/g) in week 3. Populations of MAE110 were significantly higher (P<0.05) than those of MAE119 from day 3 after inoculation. In the first year, nine fruits collected from one of the 42 MAE119 inoculated plants were positive for S. enterica Typhimurium. In the second year, Salmonella was detected in adjacent non-inoculated leaves of eight tomato plants (five inoculated with strain MAE110). The pulp of 12 fruits from two plants inoculated with MAE110 was Salmonella positive (about 106 CFU/g). Internalization was confirmed by fluorescence and confocal laser microscopy. For the first time, convincing evidence is presented that S. enterica can move inside tomato plants grown in natural field soil and colonize fruits at high levels without inducing any symptoms, except for a slight reduction in plant growth
