The Analysis of Multivariate Group Differences Using Common Principal Components

Although it is simple to determine whether multivariate group differences are statistically significant or not, such differences are often difficult to interpret. This article is about common principal components analysis as a tool for the exploratory investigation of multivariate group differences and its relation to traditional statistical methods and structural equation modeling. Real data are used for illustration.     

Does Childhood Reading Disability or Its Continuance Into Adulthood Underlie Problems in Adult-Age Psychosocial Well-Being? A Follow-Up Study

ABSTRACT

This follow-up study aimed at a better understanding of the associations of reading disability (RD) with adult-age psychosocial well-being. We compared adult-age psychosocial well-being in 48 individuals (20–39 years) with documented childhood RD but without comorbid disabilities to 37 matched controls. The associations of psychosocial well-being with childhood and adult-age reading fluency were studied in the RD group, controlling for IQ, gender and unemployment. Psychosocial well-being was assessed with commonly used self-report questionnaires. No group differences were found in psychosocial well-being. In the RD group, lower adult-age reading fluency was associated with symptoms of depression, lower self-esteem, and social functioning. Severity of childhood RD was not associated with psychosocial well-being. Thus, reading fluency problems continuing into adulthood appear to be related to adult-age psychosocial well-being. A more holistic approach to studying how RD impacts adult-age well-being is needed, including both the individual’s developmental history and current functioning in various domains.     

Accelerometry-Based Characteristics of Overall Sedentary Behavior and Sitting in Middle-Aged Adults

ABSTRACT

The purpose of this study was to describe the accelerometry-based characteristics of overall sedentary behavior (SB) and sitting among adults under free-living conditions. Thirty-six (mean age 47.6 years) volunteers carried a waist-worn accelerometer for ≥4 days with data ≥600 min/d during 14 consecutive days. A machine learning (ML) based method was used to classify the patterns of SB and sitting from raw 3D acceleration. The participants spent most (69.3%) of their waking time in SB, and a half (52.2%) of the SB was performed in a sitting posture. Men broke their overall sedentary time less often (4.1 vs. 6.1 bouts/h), but women sat more; however, women broke their sitting time as often as men (7.6 bouts/h). This study confirms that SB and sitting can be distinguished using ML methods, and more information about SB can be achieved when overall SB and sitting are analyzed separately in free-living conditions.

Everlasting Friends and Enemies? Finnish University Personnel’s Perceptions of Internal Quality Assurance in 2010 and 2017

ABSTRACT

Even though quality assurance has played a role in European higher education for decades by now, it is still a topic of great discord. While several studies have focused on the initiation phase of quality assurance, little attention has been paid to the question on how attitudes towards quality assurance in higher education change over time. This study compares the attitudes of Finnish university personnel using data from 2010 and 2017. The results show that personnel experience quality assurance as slightly better in 2017 than in 2010, while differences concerning gender, personnel group and type of university persist. The findings underline the importance of implementing quality assurance in a stakeholder-specific way.     

Adults’ Use of Mathematics and Its Influence on Mathematical Competence

The Programme for the International Assessment of Adult Competencies (PIAAC) has recently drawn additional attention to “mathematical literacy” as an important influential factor for individuals’ life chances. High levels of mathematical literacy have thereby been linked to using mathematics in daily and working life frequently. In this paper, based on the data from Germany, we focus on the construct “use of mathematics” in two ways: First, we analyze in depth how it can be utilized to describe different groups of adults. Second, we investigate its role as predictor of mathematical competence and mediator of other relevant background variables. Results show that three groups of adults can be distinguished that use mathematics differently in daily and working life. However, the construct can sensibly be described as unidimensional. In a path model, “use of mathematics” turns out to be the strongest predictor of mathematical competence. In addition, it mediates effects of the mathematical requirements of the job, duration of education, and gender.     

Reception of the quality assurance commitments of the Bologna process in Finnish higher education institutions

This article analyses Finnish higher education institutions’ reception of the implementation of the new quality assurance systems that governments participating in the Bologna Process have committed to establishing in the Berlin Communiqué of 2003. The data were collected using a web survey and the respondents were classified with a cluster analysis. The reception was more positive in the polytechnics than in the research universities and women were more positive than men. People working in managerial positions were most positive about, and committed to, quality assurance. Most critical were young researchers in research universities working in temporary jobs. Some opinions were so strongly shared that respondents with short work experience expressed their opinions, even though they could not have personal experience of the topic in question. For some topics, respondents without personal experience, but having a critical attitude, tended to give their opinion whereas those with neutral attitude abstained from commenting.     

Caught up in the past? Social inclusion,skills, and vocational education and training policy in England

Since the mid-1990s, governments of different political persuasion have tried to reform VET policy to address problems in skills formation and social inclusion. Despite considerable policy activism, success has been somewhat limited, and England failed to overcome the problems associated with its liberal training regime. This article assesses the failure in vocational skills formation as a political economy and a public policy problem. It challenges the determinism in the political economy literature, points to poor public policy-making, and outlines possible policy levers.     

Implicitly measuring attitudes towards inclusive education: a new attitude test based on single-target implicit associations

Recent research on attitudes towards inclusion uses almost exclusively explicit measures such as questionnaires. Unfortunately, explicit attitude measures are biased by social desirability, particularly when the attitude object is ‘sensible’, as with inclusive education. Implicit attitude measures are less prone to social desirability, but research on implicit attitudes towards inclusive education is scarce. Thus, we introduce a new attitude measure based on the Single-Target Implicit Association Test (ST-IAT). In our study, 163 teacher students took the new implicit attitude test and completed questionnaires on their explicit attitudes towards inclusive education and persons with disabilities and a comprehensive scale on socially desirable responding. The results support the psychometric quality of our ‘Inclusion ST-IAT’. The implicit and explicit attitude measures are correlated but empirically distinct. Furthermore, the social desirability scores were associated with explicit but not with implicit attitudes towards inclusion, i.e. our measure of attitudes towards inclusion (a sensible topic) was not biased by social desirability. We propose that implicit measures should be used to reduce the influence of social desirability in inclusive education research. To encourage replications, we outline important research questions and provide the source code of our ST-IAT, which is open and free to use.     

Are habitual runners physically inactive?

The World Health Organisation’s (WHO) physical activity guidelines recommend 150min/week of moderate- to vigorous-intensity physical activity (MVPA) accumulated in 10 min bouts. To see whether people performing habitual exercise for recreation meet these guidelines, 25 long-distance runners [mean 67 km/wk], 25 joggers [mean 28 km/wk], and 20 sedentary adults wore an ActiGraph GT3X+ accelerometer for 7 days. Sedentary time and bouts were similar in runners and sedentary adults (p > 0.46). Sedentary adults performed 20 ± 16 min/day of MVPA (usual bout duration (W50%): 9.53 ± 3.45min), with joggers and runners performing 45 ± 31min (W50%: 16.92 ± 9.53min) and 83 ± 58min (W50%: 20.35 ± 8.85min), respectively (p ≤ 0.001 versus sedentary group). Data showed that 65% of the sedentary group, 32% of joggers and 4% of long-distance runners did not meet the WHO guideline for MVPA. Failure to meet the guideline was most prominent in, but not restricted to, runners who reported ≤50km running per week. Self-reported running does not ensure adults meet physical activity guidelines or offset daily sedentary behaviours. On the other hand, the sedentary group was very close in accumulating recommended bouts of MVPA in incidental activities. Future studies should assess whether modification of work and leisure physical activity would be more fruitful than encouraging recreational exercise per se in meeting physical activity guidelines.
