Darlington and the 'invention' of the chromosome

Cyril Dean Darlington (1903-1981) has been forgotten by historians, but was in his day, the leading cytologist of the premolecular era. Of humble and inconspicuous beginnings, Darlington started his career as an unpaid volunteer worker under the aging William Bateson. Working in almost total isolation and with no scientific guidance, he boldly deduced the laws of chromosome behaviour, making cytology relevant once again both to genetics and to evolutionary theory. This process did not proceed smoothly, for both Darlington's method, and cross-disciplinary approach made the reception of his novel ideas difficult. This article examines Darlington's contribution to the premolecular understanding of Life, and the reasons why it was so difficult to accept.     

The Self‐Generative Mind in Education: Review and Future Directions

Since the turn of the millennium, there has been a surge of interest in diverse forms of spontaneous thinking, such as mind‐wandering, and their associated brain networks. Studies demonstrate the pervasiveness of these phenomena as well as their effects on education‐relevant domains such as academic skills, well‐being, creativity, executive functions, and socioemotional competencies. Based on a neurophenomenological approach and drawing on cognitive and neuroscience research, this article reviews this field and develops a framework for understanding deliberate and nondeliberate states of students' minds in the classroom and their associated brain circuitry. Different approaches to these states are examined from an educational perspective and ways in which this discourse can further be developed are suggested.     

Re-thinking skill through a new lens: evidence from three Australian service industries

The purpose of this paper is to provide another perspective on the problematic nature of the concept of skill and in particular a tendency to place a lower value on certain types of job in the service sector than those in other industries. Qualitative research was conducted in three service industries in Australia, comprising interviews with key industry stakeholders, case studies in two companies for each of four occupations, and validation by a forum of industry experts. We present evidence of the existence of substantial levels of skill in occupations which are traditionally considered low-skilled. The data are utilised to create a new model which represents factors which contribute to perceptions of skill in occupations. The analysis extends and deepens current understanding of aspects of skill, primarily, but not only, building on social construction theory to posit a new model for analysing skill. New factors are added to the analysis of skill in occupations. The project was exploratory and covered only four occupations in three industry areas. The method could be utilised in a broader-scale project. The paper is designed to contribute to debates on the nature of skill and also has policy and practical implications in the fields of human resource practice and training.     

Predicting academic achievement by class‐level emotions and perceived homeroom teachers’ emotional support

Using a multilevel approach, this study examined the role of classroom emotional climate on students' academic achievement. Positive and negative emotions and homeroom teachers' support were used to assess the classroom emotional climate on the individual and class levels. To our knowledge, no study to date has investigated these specific aspects of the classroom emotional climate in relation to students' GPA. Data were collected from 73 classrooms in grades 7‐12 (N = 1,641, students; 53% female) across three schools in Israel. Findings revealed that aggregated levels of both positive affect and perceived homeroom teacher support were positively tied to GPA and that aggregated levels of negative affect were negatively tied to GPA. The final model included gender, teacher support, individual and class emotions and explained 14% of within‐class GPA. A central implication of this study is the relevance of having an emotionally supportive homeroom teacher for students' academic achievement.

Differential Prediction in the Use of the SAT and High School Grades in Predicting College Performance: Joint Effects of Race and Language

The literature on differential prediction of college performance of racial/ethnic minority students for standardized tests and high school grades indicates the use of these predictors often results in overprediction of minority student performance. However, these studies typically involve native English‐speaking students. In contrast, a smaller literature on language proficiency suggests academic performance of those with more limited English language proficiency may be underpredicted by standardized tests. These two literatures have not been well integrated, despite the fact that a number of racial/ethnic minority groups within the United States contain recent immigrant populations or heritage language speakers. This study investigates the joint role of race/ethnicity and language proficiency in Hispanic, Asian, and White ethnic groups across three educational admissions systems (SAT, HSGPA, and their composite) in predicting freshman grades. Our results indicate that language may differentially affect academic outcomes for different racial/ethnic subgroups. The SAT loses predictive power for Asian and White students who speak another best language, whereas it does not for Hispanic students who speak another best language. The differential prediction of college grades of linguistic minorities within racial/ethnic minority subgroups appears to be driven by the verbally loaded subtests of standardized tests but is largely unrelated to quantitative tests.     

Examining Effective Intervention Practices for Communication Impairment in Autism Spectrum Disorder

This article describes effective communication-related practices by reviewing specific evidence-based techniques, sharing how these techniques have been used in various treatment approaches, and discussing a constellation of general principles vital to treatment success. A comprehensive model of service delivery is provided to illustrate these key features of effective practice within the ecological and cultural contexts of families and their everyday lives.
