Successful Scholarly Communication at a Small University: Integration of Education,Services, and an Institutional Repository at Valparaiso University

Beginning in 2011, the Christopher Center Library Services (CCLS) unit at Valparaiso University (VU) started implementing new scholarly communication services utilizing two different components: (1) the education and training of library staff in scholarly communication trends and issues; and (2) the implementation of ValpoScholar, VU's institutional repository (IR) and its associated services. These components allowed for new skills to be developed, new services to be delivered, and the library's digital collections to grow with minimal impact to existing services. This model may provide a framework for other small institutions interested in adding scholarly communication services to their existing library services.     

Selective electrochemical production of hydrogen peroxide at zigzag edges of exfoliated molybdenum telluride nanoflakes

The two-electron reduction of molecular oxygen represents an effective strategy to enable the green, mild and on-demand synthesis of hydrogen peroxide. Its practical viability, however, hinges on the development of advanced electrocatalysts, preferably composed of non-precious elements, to selectively expedite this reaction, particularly in acidic medium. Our study here introduces 2H-MoTe₂ for the first time as the efficient non-precious-metal-based electrocatalyst for the electrochemical production of hydrogen peroxide in acids. We show that exfoliated 2H-MoTe₂ nanoflakes have high activity (onset overpotential ∼140 mV and large mass activity of 27 A g⁻¹ at 0.4 V versus reversible hydrogen electrode), great selectivity (H₂O₂ percentage up to 93%) and decent stability in 0.5 M H₂SO₄. Theoretical simulations evidence that the high activity and selectivity of 2H-MoTe₂ arise from the proper binding energies of HOO^* and O^* at its zigzag edges that jointly favor the two-electron reduction instead of the four-electron reduction of molecular oxygen.     

Effects of a Research-Infused Botanical Curriculum on Undergraduates’ Content Knowledge,STEM Competencies,and Attitudes toward Plant Sciences

In response to the American Association for the Advancement of Science''s Vision and Change in Undergraduate Biology Education initiative, we infused authentic, plant-based research into majors’ courses at a public liberal arts university. Faculty members designed a financially sustainable pedagogical approach, utilizing vertically integrated curricular modules based on undergraduate researchers’ field and laboratory projects. Our goals were to 1) teach botanical concepts, from cells to ecosystems; 2) strengthen competencies in statistical analysis and scientific writing; 3) pique plant science interest; and 4) allow all undergraduates to contribute to genuine research. Our series of inquiry-centered exercises mitigated potential faculty barriers to adopting research-rich curricula, facilitating teaching/research balance by gathering publishable scholarly data during laboratory class periods. Student competencies were assessed with pre- and postcourse quizzes and rubric-graded papers, and attitudes were evaluated with pre- and postcourse surveys. Our revised curriculum increased students’ knowledge and awareness of plant science topics, improved scientific writing, enhanced statistical knowledge, and boosted interest in conducting research. More than 300 classroom students have participated in our program, and data generated from these modules’ assessment allowed faculty and students to present 28 contributed talks or posters and publish three papers in 4 yr. Future steps include analyzing the effects of repeated module exposure on student learning and creating a regional consortium to increase our project''s pedagogical impact.

Decreased sympathetic cardiovascular influences and hormone-physiological changes in response to Covid-19-related adaptations under different learning environments

To examine the implications of the transition from face-to-face to online learning from a psychobiological perspective, this study investigated potential differences in physiological stress parameters of students engaged in online or face-to-face learning and determined whether these can be identified as possible mediators between learning experience and achievement emotions. In a randomized experimental field study, medical students (n = 82) attended either regular face-to-face classes of the microscopic anatomy course or the same practical course online using Zoom videoconferencing platform. The present study investigated Heart Rate Variability (HRV) and salivary cortisol concentration as stress correlates, within the contexts of online and face-to-face learning and compared these parameters with a control group that was measured at rest. Additionally, participants completed a standardized questionnaire about their experienced emotions in relation to task achievement and subjective stress levels. A significant reduction in HRV was found in face-to-face learning, suggesting stronger stress responses in the face-to-face learning environment (η² = 0.421, P < 0.001). Furthermore, participants engaged in face-to-face learning showed significantly higher cortisol concentrations (η² = 0.115, P = 0.032). Additionally, increased sympathetic activation correlated with the discrete positive emotion of enjoyment exclusively within the face-to-face condition (r = 0.365, P = 0.043). These results indicate that the transfer of a face-to-face practical course in microscopic anatomy to an online learning environment is associated with decreased sympathetic and enhanced vagal cardiovascular influences, together with lower cortisol concentrations in healthy medical students.     

Values: Roots or Fruits? Shifting the Emphasis in Values Education

Jonathan Long suggests that current interpretations of values education are dominated by a number of ideas that appear to make attempts to achieve clarity and consensus extremely difficult. He argues that 'essential to the successful development and promotion of values in a secular state educational system is a shifting of emphasis which enables us to see the context as an opportunity rather than a problem'. He goes on to suggest that schools should focus on what he describes as the 'roots' of values. In his view, these roots involve the questions 'What is it to be human?' and 'What counts as human flourishing?'. Thus, schools must engage with issues of identity and direction.

Breaking the cycle of intergenerational abuse: the long-term impact of a residential care program

OBJECTIVE: The number of youth in residential care programs who have been abused is high. The relationship between childhood abuse victimization and adult intimate partner violence (IPV) is well documented. This study compared the rates of IPV 16 years after individuals had participated in a long-term residential care program with individuals accepted to the program who did not participate. The IPV rates for these two groups were also compared to national normative data. METHOD: Information on adult functional outcomes was obtained from former residential care and comparison youth via a confidential survey that was administered either by telephone or by mail. Analysis was limited to respondents who were currently married or involved in a marriage-like relationship (n=131; 92% male). RESULTS: The IPV rates for the sample were 9.3% for those who stayed in the residential program less than 18 months and 6.5% for those who stayed more than 18 months, neither of which were significantly different from the national norm of 8.4%. The IPV rate for the comparison group was 26.1%, which was significantly higher than the national norm. Regardless of length of program stay, respondents who were maltreated in childhood had a 14.5% IPV rate, which was significantly lower than the estimated 36-42% rate projected for individuals with similar backgrounds. CONCLUSION: We conclude that time spent in a treatment-oriented residential care program was associated with lower adult IPV rates. Specifically, the skills taught in a long-term, treatment-based residential program (e.g., healthy interpersonal relationships, self-government) may have a long-term beneficial impact for adolescents at high risk of adult IPV.     

Predicting Meaningful Employment for Refugees: The Influence of Personal Characteristics and Developmental Factors on Employment Status and Hourly Wages

Refugee demographic and developmental variables were evaluated as predictors of employment outcomes following a six-month non-governmental organization (NGO) directed resettlement period. The sample consisted of 85 refugee adults (18 to 54 years) who were resettling in a medium sized urban setting in the western United States. Demographics included sex, age, education level, and English proficiency. Developmental factors included number of years spent as a refugee. Results suggested that for each year spent as a refugee there was a corresponding decrease in the ability to secure meaningful employment. Implications for vocational interventions with refugees are discussed within the framework of Social Cognitive Career Theory.
