Power,Perceptions, and Relationships: A Model of Co-Teaching in Higher Education

Co-teaching has historically been used in K–12 education to provide students with disabilities access to general curriculum; therefore, much of the co-teaching literature has focused on the K–12 population. Research on collegiate co-teaching has been more limited and largely focused on the advantages and disadvantages of co-teaching, omitting important factors that affect relationships between partners. This qualitative study involved seven interviews of co-teachers of graduate and undergraduate classes in order to better understand interactions between college-level co-teaching dyads. Data analysis revealed themes of power and authority structures, dynamics of co-teaching relationships, and co-teachers' perceptions related to advantages of co-teaching, disadvantages of co-teaching, and student experiences. The researchers developed the Circular Model of Collegiate Co-Teaching, an original model to explain how these themes and subthemes are interrelated and affect each other. Specific best practices and new insights for collegiate co-teaching practice are discussed.     

Effects of identical context on visual pattern recognition by pigeons

The effects of identical context on pattern recognition by pigeons for outline drawings of faces were investigated by training pigeons to identify (Experiment 1) and categorize (Experiment 2) these stimuli according to the orientation of the mouth—an upright U shape representing a smiling mouth or an inverted U shape representing a sad mouth. These target stimuli were presented alone (Pair 1), with three dots in a triangular orientation to represent a nose and eyes (Pair 2), and with the face pattern surrounded by an oval (Pair 3). In Experiment 1, the pigeons trained with Pair 1 were most accurate, those trained with Pair 2 were less so, and those trained with Pair 3 failed to acquire the discrimination within eighty 100-trial sessions. The same ordering was found in Experiment 2 for pigeons trained on the three pairs simultaneously. The authors suggest that a contrasting finding in humans, the face superiority effect, might be due to a gain in discriminability resulting from recognition of the pattern as a face. An exemplar model of information processing that excludes linguistic coding accounts for the present results.     

Blurring the color line: The desegregation of the Baltimore city public schools, 1954–1994

Perched on the Mason-Dixon line, Baltimore ignored calls for resistance from its southern neighbors by becoming one of the first cities in the country to comply withBrown. By the beginning of the 1955 school year, leaders had implemented a desegregation plan, and Baltimore was being applauded for the early and peaceful integration of its public schools. Within a few years, however, the praise faded as it became clear that Baltimore still suffered from de facto segregation. Faced with this reality, the school board refused to take the steps necessary to remedy the problem, instead shifting the blame to society at large. This failure by the board started a pattern of abandonment by school leadership that culminated in 1991 with the privatization of several of Baltimore's public schools. The result of this abandonment is a crippled school system that still has not dealt with issues of race and equality.     

Context-sensitive regularities in English vowel spelling

The predictive value of rime spellings in English was compared directly to other types of regularities beyond the level of the single letter. A computer-assisted analysis of a list of twenty-four thousand written words, each paired with its corresponding pronunciation, reveals that only a small number of rime spellings are highly regular in their pronunciations. The conventional division of vowel letter pronunciations into short and long in closed and open written syllables is the most reliable key to English pronunciation. Our findings support the notion that English spelling is based at least in part on syllable structure. In addition, prefixes and suffixes provide very reliable clues to pronunciation, which suggests that their regularity should be exploited in the teaching of reading.     

Appropriability of innovation benefit as a predictor of the source of innovation

It has been empirically observed that, in some industries product users are the most frequent sources of product innovations while, in other industries, product manufacturers are. I hypothesize that such differences are caused by differences in the ability of these two “functional” categories of innovators to appropriate innovation benefit. I explore this hypothesis by examining the real-world effectiveness of mechanisms (such as patents and lead time) used for the appropriation of innovation benefit and the dependence of this effectiveness on the functional relationship between innovator and innovation.     

Marital conflict and conduct problems in Children of Twins

The Children-of-Twins design was used to test whether associations between marital conflict frequency and conduct problems can be replicated within the children of discordant twin pairs. A sample of 2,051 children (age 14-39 years) of 1,045 twins was used to estimate the genetic and environmental influences on marital conflict and determine whether genetic or environmental selection processes underlie the observed association between marital conflict and conduct problems. Results indicate that genetic and nonshared environmental factors influence the risk of marital conflict. Furthermore, genetic influences mediated the association between marital conflict frequency and conduct problems. These results highlight the need for quasiexperimental designs in investigations of intergenerational associations.     

Emotional energy and sub-cultural politics: alternative bands in post-1997 Hong Kong

The paper attempts to work out the link between the structuring of the public domain and hegemonic masculinities in contemporary Kerala, South India. Using the debates around an incident of sexual harassment that happened in 1999, it argues for a conjunctural understanding of the contemporary where various events and moments in history are replayed through narrativization and popular memory. The paper goes on to analyse the debates around the incident that produce a ‘narrative public domain’, to foreground the various notions of masculinity that construct and structure it in relation to notions of female sexuality and changing structures of family. These notions of masculinity could be, the paper argues, a starting point for a historical inquiry into Kerala's modernity – an inquiry that would throw light on the past and the ways in which the contemporary is produced through its historical legacies.
