Connecting brawn,brains, and people: an exploration of non-traditional outcomes of youth stewardship programs

Programs in which youth work collectively on an environmental stewardship project may provide social learning opportunities that support social-ecological system resilience and the development of social ties. However, few empirical investigations document the social learning processes that actually occur in these programs. This paper presents a multi-case study ethnography of six summer youth civic ecology education programs. Methods included participant observation, interviews, and group mind-mapping. The results suggest that programs offered moderate social learning contexts, with participants having little say over the direction and design of the program’s environmental stewardship goals. Nevertheless, participants worked together and collaborated on projects led by program leaders, with whom they developed strong ties. In programs focused on a single issue in one place, participants shifted their conceptual frames to include locally relevant concepts. While participants did not form strong ties with other program participants or with individuals from outside programs, they valued experiences where they led volunteers or were observed by others doing stewardship work. These results suggest that environmental stewardship programs can be designed to enhance social learning opportunities, which could incorporate strategies to increase youth developing ties with each other and with outside organizations.     

Acquisition and extinction of runway performance under escape,avoidance, and partial-avoidance procedures

The acquisition and extinction of locomotor responses of rats in a straight alley were examined for groups trained under escape, partial-avoidance, and avoidance procedures. During acquisition, one group (escape) received a 0-sec delay between being dropped into the alley and the onset of shock; two groups (partial avoidance) had 0.5- and 1-sec delays; and two groups (avoidance) had delays of 2 and 4 sec. On the final day of acquisition, the partial-avoidance rats displayed higher running speeds than either the escape- or avoidance-trained animals. The 4-sec avoidance group was consistently slower than all other groups. Speeds for all groups decreased during extinction, with rate of decline showing some relation to terminal acquisition level. Relative group performance levels proved to be consistent with a simple arithmetic model based on the assumption that changes in running speeds affect the aversiveness of the situation by altering US duration, CS duration, and effective US length.     

SCALE‐UP OF SAFE & CIVIL SCHOOLS’ MODEL FOR SCHOOL‐WIDE POSITIVE BEHAVIORAL INTERVENTIONS AND SUPPORTS

This study evaluated the scale‐up of a Safe & Civil Schools Foundations: Establishing Positive Discipline Policies positive behavioral interventions and supports initiative through 4 years of “real‐world” implementation in a large urban school district. The study extends results from a previous randomized controlled trial that established the effectiveness of the Safe & Civil Schools program in 32 elementary schools in the same district. This study emphasizes the application and evaluation of the program in regular district schools. Four‐year results indicate that elementary, middle, and high schools experienced moderate but steady improvements in (a) school discipline, (b) student safety policy and training, (c) staff perceptions of student behavior, and (d) student suspension and chronic tardiness rates. With few exceptions, improvements occurred after schools began Safe & Civil Schools Foundations training, and more years of training were associated with larger cumulative improvements in school and student outcomes. Given that similar effects were observed in schools with and without random assignment of training, and only after training began, we concluded that the improvements stem from Safe & Civil School's Foundations training.     

Inquiry identity and science teacher professional development

An effective inquiry-oriented science teacher possesses more than the skills of teaching through investigation. They must address philosophies, and ways of interacting as a member of a group of educators who value and practice science through inquiry. Professional development opportunities can support inquiry identity development, but most often they address teaching practices from limited cognitive perspectives, leaving unexplored the shifts in identity that may accompany teachers along their journey in becoming skilled in inquiry-oriented instruction. In this forum article, we envision Victoria Deneroff’s argument that “professional development could be designed to facilitate reflexive transformation of identity within professional learning environments” (2013, p. 33). Instructional coaching, cogenerative dialogues, and online professional communities are discussed as ways to promote inquiry identity formation and collaboration in ways that empower and deepen science teachers’ conversations related to personal and professional efficacy in the service of improved science teaching and learning.     

Trade-offs between knowledge exploitation and exploration activities

This paper explores trade-offs between knowledge exploitation and exploration activities. The study of exploitation and exploration activities is not new; however, rarely has past research perceived exploitation and exploration activities as two edges of one continuum. Furthermore, little evidence has been reported as to the actual trade-offs that firms face when launching either exploration or exploitation activities. This paper sets about filling this gap by addressing the following question: To what extent does an investment in one exploitation activity hinder the development of an exploration activity within the firm? A new process innovation targeting the exploitation of the firm's internal capabilities through an extensive component reuse and reconfiguration program is studied and the implications for inter-related exploration activities, such as the development of engineers' expertise is examined. To reveal the trade-offs between exploration and exploitation activities, both changes within and between these exploitation and exploration activities, over time, are studied. Based on data drawn from an in-depth study of several product development project teams in one high-tech company, we conclude that by investing in exploitation activities, a firm may limit some specific exploration activities.     

What do individuals in different science groups within a life sciences organization think about genetic modification?

An assessment was undertaken of the attitudes of individuals within the science community towards a program to produce genetically modified cattle for altered milk composition, expectantly allowing for research into the treatment of multiple sclerosis in humans. The majority of respondents to an electronic survey expressed favorable attitudes to the program, thought it beneficial, respected individual freedom and was fair and just and disagreed that it was harmful. A passion for science and having a suitable lifestyle were the most important motivating factors for individuals. Finally, there were a wide range of responses to a number of cultural beliefs or myths. Science grouping significantly affected the responses. Compared with Systems and Land groups, Plant and Reproduction groups more strongly agreed with the project, thought it less harmful to interest groups, felt that genetic modification of animals was more morally acceptable, and more strongly agreed with the myth statements. These results indicate a diversity of beliefs and attitudes towards genetic modification amongst those within the science community, and highlight the importance of understanding ethics and myths in dealing with them. It is suggested that the diversity of beliefs could be better used to help shape public policy and understanding of biotechnology.     

How cells communicate: the system used by slime moulds

The way in which cells in multicellular organisms communicate and inform each other of their presence and relative position is an intriguing but mysterious problem. The form of communication used during the phase of aggregation in the cellular slime moulds represents a particularly amenable system for study. When these organisms run short of nutrients, some of the cells of the amoebal population emit rhythmic pulses of cyclic adenosine monophosphate. These chemical signals are slowly relayed to all the other amoebae within range and bring about an ordered migration of them towards the pulsating centre and the triggering of cellular development.
