Factors contributing to high PhD completion rates: a case study in a research-intensive university in New Zealand

This exploratory study determined PhD completions at a research-intensive university in New Zealand and considered factors affecting PhD completions. Completion data were calculated for PhD cohorts at the University of Otago from 2000 to 2012 (n = 2770) and survival models determined whether gender, enrolment status, age at admission, citizenship, scholarship status and academic field influenced completion. The impact of the doctoral programme and the research environment was also considered. Across all cohorts, 83% submitted their thesis for examination (17% withdrawal). The median submission time was 3.4 years for full-timers, with a median completion time (to award of degree) of 4.1 years. Survival modelling showed that completion can be enhanced by having mainly full-time candidates, but also allowing periods of part-time enrolment near submission, recruiting a large international cohort, and providing three year scholarships. Health science candidates had the highest submission percentages, while commerce candidates submitted in the fastest times. There were only minor or negligible effects of gender and age at admission. Other factors contributing to high submission rates included recruiting quality candidates, close monitoring during candidature, provision of research training, a vibrant research culture, a personal performance coach, high-quality supervision and funding incentives for candidates who submit in under four years.     

Remembering: The role of extraneous reinforcement

In two experiments, pigeons' responding on an extraneous task was explicitly reinforced during delayed matching-to-sample trials. In Experiment 1, red or green sample stimuli were followed by retention intervals of 0.2, 1, 4, or 12 sec, during which pecks to a white center key were reinforced with 2.5-sec access to wheat according to extinction, variable-interval 30-sec, and variable-interval 15-sec schedules in different conditions. A proportion of .2, .5, .7, or .9 of subsequent red or green choice responses that matched the sample were reinforced with 3-sec access to wheat. The result was that increasing center key reinforcement, or reducing reinforcer probability, lowered overall accuracy. Initial discriminability fell, but with no change in the rate of forgetting. In Experiment 2, initial discriminability was affected by extraneous reinforcers that were contingent on center key pecking, but not by noncontingent reinforcers. A plausible conclusion is that initial discriminability decreases when reinforcers strengthen competing behaviors.

Standardization of Work: Co-constructed Practice

There is strong pressure to achieve greater uniformity, standardization and application of best practices in the service professions, a sector that is growing in presence and importance. At the same time, there is a conflicting demand for the delivery of high-quality (or high-priced or “knowledge-intensive”) specialized or localized services. Our article analyzes information systems-enabled standardizing of service work through an in-depth interpretative study of an ongoing standardization initiative within the field of nursing. Nursing provides a graphic illustration of the dilemmas involved in the standardization of service work. In nursing, standardization is commonly a feature of projects to improve both efficiency and quality in health care. In contrast to the dominant conception of standardization as a largely top-down, imposed process, we offer a view of standardization as incomplete, co-constructed with users, and with significant unintended consequences. The article contributes by (a) developing a theoretical perspective for the standardization of information-system-embedded service work and (2) providing operational and practical implications for system design and health care management.     

Cultural Differences in Maternal Beliefs and Behaviors: A Study of Middle-Class Anglo and Puerto Rican Mother-Infant Pairs in Four Everyday Situations

This study examines cultural patterning in situational variability in mother-infant interactions among middle-class Anglo and Puerto Rican mothers and their 12 to 15-month-old firstborn children. Forty mothers were interviewed regarding their long-term socialization goals and childrearing strategies, and videotaped interacting with their infants in four everyday settings: feeding, social play, teaching, and free play. Results suggest that: (1) Anglo mothers place greater emphasis on socialization goals and childrearing strategies consonant with a more individualistic orientation, whereas Puerto Rican mothers place greater focus on goals and strategies consistent with a more sociocentric orientation; (2) coherence was found between mothers' childrearing beliefs and practices, with Puerto Rican mothers more likely to directly structure their infants' behaviors; and (3) situational variability arose in mother-infant interactions, but this variability showed a cultural patterning consistent with mothers' long-term socialization goals and childrearing beliefs.     

Network Mediated Discursive Education: From Computational to Networked Knowledge in the University

In the 1990s, knowledge management originated as a post-Fordist, information society, discourse that stressed the sociotechnical “capture” and distribution of knowledge as a sharable, information resource. Following a postindustrial model, the information/knowledge economy was seen as the leading productive sector. Today's networked systems mix information processing and retrieval and communication technologies in new ways. While such systems demand new tools for capturing, organizing, searching, ranking, and visualizing knowledge, such systems also offer new opportunities for education and for better, shared, research. This article reviews the status of computational technologies in university education in, and since, Jean-François Lyotard's The Postmodern Condition: A Report on Knowledge and then offers recommendations on bridging the divide between networked and critical thinking through the reorganization of the university and some of its functions.     

Research and practice in science education: a response to Traianou and Hammersley

A reader of Traianou and Hammersley’s article (in this issue), which discusses at some length the work we undertook in the Evidence‐based Practice in Science Education (EPSE) Research Network, might attribute to us views that are rather different from those which we in fact hold, and which we have sought to present in our own accounts of this work. We highlight several points on which their interpretation of our work and views differs markedly from ours. The aim of the EPSE Network was to explore the practical implications of ‘evidence‐based practice’ in the context of a mainstream curriculum subject such as science, not to advocate any particular interpretation of that term. We would encourage readers interested in the relationship between research and practice in the teaching of specific subjects to base their view of our work, and the perspectives underpinning it, on our own account.     

Epistemological understanding in science learning: the consistency of representations across contexts

This article addresses the extent to which written diagnostic questions can be used to assess science students' representations of the nature of science. The responses of 731 European science students in upper secondary school and undergraduate programmes to two written diagnostic questions are analysed for consistency. The written questions yielded some insights into students' views. There is evidence that the majority of students in this sample draw upon different epistemological representations in different contexts. The paper concludes with a discussion of the use of data from such questions in science education, and the significance of models of students' epistemological knowledge.     

Word-Level Evidence of the Role of Phonological Decoding During Orthographic Learning: A Direct Test of the Item-Based Assumption

The goal of this study was to test the item-based assumption of the self-teaching hypothesis by reanalyzing Cunningham’s (2006) data. In Cunningham’s study, 37 first graders participated in a self-teaching experiment, and their orthographic learning was measured by a spelling task and an orthographic choice task. A 2-level logistic regression model was used to analyze accuracy of phonological decoding of a target word and spelling acquisition of that word. The findings suggest that the probability of spelling a target word correctly increases as the decoding accuracy of the target word increases. In contrast, this relation was not found for the orthographic choice task. The discrepancy in the results between the 2 dependent measures might be due to the difference in cognitive processes required to complete a production task as opposed to a recognition task. The current findings provide item-based evidence for the accuracy of phonological decoding on participants’ performance on a spelling task.
