Formal numerical characteristics of closed constrained incremental successive substitution algorithms

This paper establishes the formal numerical characteristics of closed constrained incremental successive substitution algorithms. The overall formalism gives detailed consideration to such items as the determination of: safety zones wherein the algorithm possesses inherently stable convergence characteristics; existence, uniqueness and convergence properties; formal limitations on the class of functions to which the scheme applies and lastly, establishes self-adaptive attributes. To simplify the presentation, the operators employed are cast in the functional format associated with nonlinear heat conduction.     

Performance capabilities and competencies at the undergraduate and graduate levels for performance improvement professionals

This quantitative study sought to identify the performance capabilities and competencies that organizations in the northern midwestern United States expect of future performance improvement professionals at the undergraduate and graduate levels. Eighty‐nine performance improvement professionals representing 89 organizations completed an online survey that captured the participants' perspective regarding undergraduate and graduate‐level performance capabilities, and undergraduate competency expectations. Results suggest that participants expect several training and development performance capabilities, a few organization developments, and no performance management performance capabilities at the undergraduate level. Several training and development capabilities, most organization development capabilities, and all performance management performance capabilities were expected at the graduate level. This definition is fundamental to support academic curricular development and the field of performance improvement.     

Mainly Openness: The relationship between the Big Five personality traits and learning approaches

In order to examine the relationship between broad personality traits and learning approaches, 852 university students completed the NEO-FFI [Costa, P. T., Jr., & McCrae, R. R. (1992). Revised NEO Personality Inventory (NEO-PI-R) and NEO Five-Factor Inventory (NEO-FFI): Professional manual. Odessa, FL: Psychological Assessment Resources] and SPQ [Biggs, J. B. (1987). The Study Process Questionnaire manual. Victoria: Australian Council for Educational Research], which assess personality and learning approaches, respectively. Seven previous studies were used to generate hypotheses on the relationship between these two measures, but only the positive link between Openness to Experience and Deep learning was supported by both correlational and structural equation modelling tests. Openness was also found to be negatively linked to Surface learning, but other Big Five traits were not saliently associated with learning approaches. Results indicate that the overlap between learning approaches and personality traits is lower than previously suggested. Implications are discussed.     

Typical intellectual engagement as a byproduct of openness,learning approaches,and self‐assessed intelligence

Students (n = 328) from US and UK universities completed four self‐report measures related to intellectual competence: typical intellectual engagement (TIE), openness to experience, self‐assessed intelligence (SAI), and learning approaches. Confirmatory data reduction was used to examine the structure of TIE and supported five major factors: reading and information seeking, intellectual avoidance, directed complex problem solving, abstract thinking, and intellectual pursuits as a primary focus. These factors were significantly and positively associated with deep learning, openness, and SAI, and negatively related to surface learning. Other correlates of TIE were more factor‐dependent. In general, correlations suggested that TIE is related to, but different from, the other intellectual competence constructs examined. Results are discussed in relation to the typical performance approach to intelligence and the importance of TIE with regards to the intrinsic motivation to learn.     

Positive Emotional Responses to Hybridised Writing about a Socio-Scientific Issue

In order to understand better the role of affect in learning about socio-scientific issues (SSI), this study investigated Year 12 students’ emotional arousal as they participated in an online writing-to-learn science project about the socio-scientific issue of biosecurity. Students wrote a series of hybridised scientific narratives, or BioStories, that integrate scientific information about biosecurity with narrative storylines, and uploaded these to a dedicated website. Throughout their participation in the project, students recorded their emotional responses to the various activities (N = 50). Four case students were also video recorded during selected science lessons as they researched, composed and uploaded their BioStories for peer review. Analysis of these data, as well as interview data obtained from the case students, revealed that pride, strength, determination, interest and alertness were among the positive emotions most strongly elicited by the project. These emotions reflected students’ interest in learning about a new socio-scientific issue, and their enhanced feelings of self-efficacy in successfully writing hybridised scientific narratives in science. The results of this study suggest that the elicitation of positive emotional responses as students engage in hybridised writing about SSI with strong links to environmental education, such as biosecurity, can be valuable in engaging students in education for sustainability.     

The open access scientific journal: an empirical study

The open access (OA) model for journals is compared to the open source principle for computer software. Since the early 1990s nearly 1,000 OA scientific journals have emerged – mostly as voluntary community efforts, although recently some professionally operating publishers have used author charges or institutional membership. This study of OA journals without author charges shows that their impact is still relatively small, but awareness of it is increasing. The average number of research articles per year is lower than for major scientific journals but the publication times are shorter.     

The links between students’ relationships with teachers,likeability among peers,and bullying victimization: the intervening role of teacher responsiveness

Highly responsive teachers tend to foster behaviors that are low in conflict and high in prosociality, among their students, leading to a positive classroom climate and to a decrease in bullying victimization. However, little is known about the interaction between teacher responsiveness and both student–teacher, and student–student relationship characteristics, in influencing students’ bullying victimization at school. Here, we examined student–teacher relationship quality and students’ likeability among peers as predictors of in-school victimization. Additionally, we investigated the moderating role of teacher responsiveness over this link. Study sample consisted of 386 early-adolescent students (55.2% female, mean age [SD] = 12.17 [0.73]) and 19 main teachers (females, n = 14). Findings indicated that students’ exposure to victimization was positively associated with student–teacher conflict and negatively associated with likeability among classroom peers. Teacher responsiveness did not show a significant direct association with bullying victimization. However, when teachers showed high responsiveness, the strength of the association between student–teacher conflict and students’ likelihood of bullying victimization was slightly increased. The present study highlights the importance of considering the role of teacher responsiveness when modeling the link between student and teacher relationship quality and in school bullying victimization.

     

Consumer databases as practical accomplishments: the making of digital objects in three movements

This paper aims to reflect on some key issues linked to the production of digital objects in business settings. In doing so, it problematizes current social science scholarship, which emphasizes the analysis of digital data and analytics, and reinforces the magnitude of its consequences and ‘data power’. The paper proposes making three corrective ‘movements’ that might enrich our approaches to how databases and analytics are assembled in business settings. The first movement involves the problem of ethnographic access to data-making practices. We propose taking seriously the issue of fabricating an ethnographic encounter where the process of making digital objects is exposed. The second movement concerns the visibility and the type of politics taking place in data practices. We argue for the need to displace attention from data impacts and results to the myriad of mundane practices and devices through which these objects are assembled. The third movement we suggest requires a focus on examining error and failure as key aspects of the manufacturing of consumer databases. Each of these movements is illustrated by ethnographic vignettes from a 9-month ethnographic experiment that involved participating in the first stages of the manufacturing of an online financial retail company's consumer database.     

Assessing pupils’ intelligence through self,parental, and teacher estimates

This study examined the accuracy of self‐ and other‐estimated intelligence in relation to tested cognitive ability and gender. Three groups of raters were examined: 187 (102 male, 85 female; mean age 14.33 years, SD = .32) pupils of single‐sex comprehensive schools, 109 (55 mothers and 54 fathers) parents, and six teachers of the pupils. Pupils estimated their own overall IQ, while their parents and teachers estimated the pupils’ overall, mathematical, spatial, and verbal abilities. Self‐ and other‐estimates were compared to each other, and to the child’s psychometric test scores in verbal, quantitative, and figural/non‐verbal reasoning ability. Results suggested that participants were reasonably accurate at estimating pupils’ intelligence – teachers significantly more so than parents, and pupils significantly more so than fathers. Although both parents significantly overestimated their child’s IQ, this overestimation was more pronounced in fathers.     

Understanding the prospect of success in professional training: an ethnography into the assessment of problem-based learning

One of the most fundamental innovations in higher education is the introduction of the method known as problem-based learning (PBL). While literature has largely focused on its learning goals and the transition from lectures to tutorials, little research has problematised why this is a successful methodology and what we consider as students’ success. Drawing upon various ethnographic techniques, the authors analyse PBL as a field of expectations in light of Expectation-Value Theory. Beyond merely showing that PBL is a culturally constructed practice, the article elaborates on how students’ expectations inform practices, performance and evaluation, which is important for assessing the successfulness of the method. By discussing students’ expectations, dynamics and power relations, the present article is a contribution to the research addressing what has come to be known as the ‘black box’ of PBL.
