Scenarios of quality assurance of stakeholder relationships in Finnish higher education institutions

Although the role and significance of the external stakeholders of higher education institutions has grown in recent years, quality assurance of stakeholder relationships remains a new phenomenon in the management practices of higher education institutions and in higher education research. Based on interviews and expert panel data, this article analyses the internal and external stakeholders’ perceptions of scenarios of the quality assurance of stakeholder relationships in Finnish higher education institutions. It especially focuses on exploring how institutions can balance internal and external stakeholders’ perspectives with regard to quality assurance. The results show that an essential challenge for Finnish higher education institutions is to develop flexible quality assurance practices capable of balancing the academic goals of the institutions and the needs of the external stakeholders. This also requires seeking balance between the centralised coordination and the differentiated practices of disciplines and academic units inside institutions.     

Domain general constraints on statistical learning

All theories of language development suggest that learning is constrained. However, theories differ on whether these constraints arise from language-specific processes or have domain-general origins such as the characteristics of human perception and information processing. The current experiments explored constraints on statistical learning of patterns, such as the phonotactic patterns of an infants' native language. Infants in these experiments were presented with a visual analog of a phonotactic learning task used by J. R. Saffran and E. D. Thiessen (2003). Saffran and Thiessen found that infants' phonotactic learning was constrained such that some patterns were learned more easily than other patterns. The current results indicate that infants' learning of visual patterns shows the same constraints as infants' learning of phonotactic patterns. This is consistent with theories suggesting that constraints arise from domain-general sources and, as such, should operate over many kinds of stimuli in addition to linguistic stimuli.     

Kindergarten teachers adjust their teaching practices in accordance with children’s academic pre‐skills

This study examined the extent to which kindergarten children’s academic pre‐skills are associated with their teachers’ subsequent teaching practices. The pre‐skills in reading and math of 1268 children (655 boys, 613 girls) were measured in kindergarten in the fall. A pair of trained observers used the Classroom Assessment Scoring System instrument to observe 49 kindergarten teachers on their emotional support, classroom organisation and instructional support in kindergarten in the spring. The results of the multilevel modelling showed that low levels of academic pre‐skills in kindergarten classrooms in the fall predicted high classroom quality in the classrooms later on. The results suggest that the overall level of children’s academic pre‐skills in the classroom plays an important role in the ways in which teachers adapt their instructional practices to the needs of a particular classroom.     

What's in a rating?

We examine the relationship between the formal ratings that principals give teachers and a variety of observable teacher characteristics, including proxies for productivity. Prior work has shown that principals can differentiate between more and less effective teachers, especially at the tails of the quality distribution, and that subjective evaluations of teachers are strongly correlated with subsequent student achievement. However, whereas prior work has relied on survey data, we consider formal ratings from a setting in which the stakes are reasonably high. We find that the ratings are correlated with an array of teacher qualities including experience for young teachers, education credentials, and teacher absenteeism. Our finding that principals reward qualities of teachers known to be related to student productivity provides reason to be optimistic about policies that would assign more weight to principal evaluations of teachers in career decisions and compensation.     

On the influence of the architecture of poly(ethylene glycol)-based thermoresponsive polymers on cell adhesion

Thermoresponsive polymer surface coatings are a promising tool for cell culture applications. They allow for a mild way of cell detachment that preserves the activity of membrane proteins—a prerequisite for reliable cell analysis. To enlarge the application range of these coatings to cells with different adhesion properties, we synthesized various novel poly(ethylene glycol)-based thermoresponsive polymers and describe how (i) their chemical structure and (ii) their surface density affect their efficiency. In order to quantify the influence of both factors, the time for cell spreading and rounding efficiency were observed. As a result, efficiency of cell rounding, which is closely correlated to cell detachment, is less affected by both factors than the time needed for cell spreading. This time can effectively be adjusted by the molecular architecture which includes the length of the polymer backbone and the side chains. Based on this work, recommendations are given for future optimization of functionality of thermoresponsive polymer coatings for cell culture applications.     

Task‐focused behaviour and literacy development: a reciprocal relationship

The purpose of this study was twofold: (a) to examine the effect of task‐focused behaviour on reading fluency, spelling and comprehension; and (b) to examine the role of the different literacy skills in subsequent task‐focused behaviour. Two hundred and seven Finnish‐speaking children were followed from preschool until their fourth year at school and were tested for reading fluency, spelling and reading comprehension. The teachers also rated the children's task‐focused behaviour. The results showed that task‐focused behaviour was a significant predictor of later reading comprehension and spelling skills. However, all three literacy skills predicted subsequent task‐focused behaviour.     

Hard Lessons for Lifelong Learners? Age and Experience in the Graduate Labour Market

The expansion of the higher education system and widening access to undergraduate study has led to growing diversity within the graduate labour supply, including increasing numbers who studied for their degrees as mature students. Analysis of graduates entering the labour market prior to the major expansion in the early 1990s indicated that those over the age of 30 had considerably more difficulty than younger graduates in accessing the career opportunities for which their education had equipped them. Is this still the case for more recent graduates? Drawing on a major qualitative and quantitative study of a class of graduates who completed their undergraduate degree courses in 1995, this paper explores early career development and employment outcomes according to age at graduation. Although we find considerable diversity among all age groups, mature graduates were more likely than their younger peers to experience difficulty in accessing appropriate employment, had a lower rate of earnings growth and expressed higher levels of dissatisfaction with their jobs.     

Exploiting Hierarchy in Text Categorization

With the recent dramatic increase in electronic access to documents, text categorization—the task of assigning topics to a given document—has moved to the center of the information sciences and knowledge management. This article uses the structure that is present in the semantic space of topics in order to improve performance in text categorization: according to their meaning, topics can be grouped together into meta-topics, e.g., gold, silver, and copper are all metals. The proposed architecture matches the hierarchical structure of the topic space, as opposed to a flat model that ignores the structure. It accommodates both single and multiple topic assignments for each document. Its probabilistic interpretation allows its predictions to be combined in a principled way with information from other sources. The first level of the architecture predicts the probabilities of the meta-topic groups. This allows the individual models for each topic on the second level to focus on finer discriminations within the group. Evaluating the performance of a two-level implementation on the Reuters-22173 testbed of newswire articles shows the most significant improvement for rare classes.
