AbstractThe scientific study of school engagement has recently been the subject of considerable interest in the field of educational psychology, and significant advances have been made in our knowledge of this construct. For instance, there is currently consensus in the scientific community that it is multifaceted, and has three dimensions: behavioral engagement, emotional engagement, and cognitive engagement. However, more advanced statistical analyses are needed to validate Spanish-language measures of school engagement, which this study proposes to do. The sample was comprised of 1,250 adolescents from Basque Country (49% boys, 51% girls) aged 12 to 15 years old (M = 13.72, SD = 1.09). The results of confirmatory factor analysis on the School Engagement Measure (Fredricks, Blumenfeld, Friedel, & Paris, 2005) supported a three-dimensional structure of school engagement (χ2(100) = 676.93, p < .001; GFI = .931; CFI = .906; IFI = .907; SRMR = .058; RMSEA = .068). Reliability indexes were satisfactory, ranging from .83 to .94. Adequate evidence of concurrent validity was found for the variable perceived school performance (p < .01). The results are discussed from an educational perspective, and with an eye to future research.

The present study examined the dimensional structure underlying the Multidimensional Schizotypy Scale (MSS) and its brief version (MSS-B). The MSS and MSS-B were developed to assess current multidimensional conceptualizations of schizotypy. We used Exploratory Graph Analysis (EGA) to evaluate the dimensional structure of the scales in two large, independent samples (n = 6,265 and n = 1,000). We then used Confirmatory Factor Analysis (CFA) to compare the fit of the theoretical dimensions with the EGA dimensions. For the MSS, EGA identified four dimensions: positive schizotypy, two dimensions of negative schizotypy (affective and social anhedonia), and disorganized schizotypy. For the MSS-B, EGA identified three dimensions, which corresponded to the theorized positive, negative, and disorganized dimensions. Based on the MSS’s EGA dimensions, we also estimated a four-factor model for the MSS-B. The CFA comparison found that the four-factor model fit significantly better than the theoretical three-factor model for both the MSS and MSS-B. In short, we propose that the four-factor model supports the theoretical model and offers a more nuanced interpretation of the negative schizotypy dimension. Our findings offer new implications for future research on the MSS and MSS-B dimensions that may provide differential associations with interview and questionnaire measures.

Abstract. We developed a new instrument designed to measure fear of intimacy in romantic relationships. We suggest assessing fear of intimacy through two dimensions: self-revelation and dependence. The Fear of Intimacy Components Questionnaire (FICQ) was validated across three studies in which a 10-item solution systematically emerged. Consistently with a two component perspective, a two-factor solution fitted data the best: fear of losing the self (FLS) and fear of losing the other (FLO). Qualitative analyses verified content validity. Exploratory and confirmatory factor analyses tested the factor structure. Multigroup analyses supported the structural invariance across gender, age, and relationship status. Both factors showed adequate discriminant validity and internal consistency, and good 3-week period test-retest reliability. Associations between the FICQ and insecure attachment orientations demonstrated convergent validity. The association between the FICQ and relationship satisfaction above and beyond a preexisting measure offered criterion validity. By going beyond traditional self-revelation-focused conception of fear of intimacy, that is, by proposing a bi-dimensional structure to fear of intimacy, we believe that this new measure will contribute to future research on fear of intimacy.

In the semiconductor industry, wafer handling introduces micro-cracks at the wafer edge and the causal relationship of these cracks to wafer breakage is a difficult task. By way of understanding the wafer breakage process, a series of nano-indents were introduced both into 20 × 20 mm (100) wafer pieces and into whole wafers as a means of introducing controlled strain. Visualization of the three-dimensional structure of crystal defects has been demonstrated. The silicon samples were then treated by various thermal anneal processes to initiate the formation of dislocation loops around the indents. This article reports the three-dimensional X-ray diffraction imaging and visualization of the structure of these dislocations. A series of X-ray section topographs of both the indents and the dislocation loops were taken at the ANKA Synchrotron, Karlsruhe, Germany. The topographs were recorded on a CCD system combined with a high-resolution scintillator crystal and were measured by repeated cycles of exposure and sample translation along a direction perpendicular to the beam. The resulting images were then rendered into three dimensions utilizing open-source three-dimensional medical tomography algorithms that show the dislocation loops formed. Furthermore this technique allows for the production of a video (avi) file showing the rotation of the rendered topographs around any defined axis. The software also has the capability of splitting the image along a segmentation line and viewing the internal structure of the strain fields.

The Fourier Transform

In Chapter 4 many two-dimensional examples were shown, in which a diffraction pattern represents the Fourier transform of the scattering object. When a diffracting object is three-dimensional, a new effect arises. In diffraction by a repetitive object, rays are scattered in many directions. Each unit of the lattice scatters, but a diffracted beam arises only if the scattered rays from each unit are all in phase. Otherwise the scattering from one unit is cancelled out by another. In two dimensions, there is always a direction where the scattered rays are in phase for any order of diffraction (just as shown for a one-dimensional scatterer in Fig. 4.1). In three dimensions, it is only possible for all the points of a lattice to scatter in phase if the crystal is correctly oriented in the incident beam. The amplitudes and phases of all the scattered beams from a three-dimensional crystal still provide the Fourier transform of the three-dimensional structure. But when a crystal is at a particular angular orientation to the X-ray beam, the scattering of a monochromatic beam provides only a tiny sample of the total Fourier transform of its structure. In the next section, we are going to find what is needed to allow a diffracted beam to be generated. We shall follow a treatment invented by Lawrence Bragg in 1913. Max von Laue, who discovered X-ray diffraction in 1912, used a different scheme of analysis; and Paul Ewald introduced a new way of looking at it in 1921. These three methods are referred to as the Laue equations, Bragg’s law and the Ewald construction, and they give identical results. All three are described in many crystallographic text books. Bragg’s method is straightforward, understandable, and suffices for present needs. I had heard J.J. Thomson lecture about…X-rays as very short pulses of radiation. I worked out that such pulses…should be reflected at any angle of incidence by the sheets of atoms in the crystal as if these sheets were mirrors.…It remained to explain why certain of the atomic mirrors in the zinc blende [ZnS] crystal reflected more powerfully than others.

Justice Climate

The measure created by H. Li offers a useful tool for investigating justice perceptions among team members or peer justice climate; however, more research is required to confirm its structure in lieu of competing models. This study provides evidence for the three-dimensional structure of peer justice climate within a multiethnic context and explores its relation to outcome variable performance. Participants were 304 undergraduate students from universities in the multiethnic, Republic of Trinidad and Tobago. Competing structures of peer justice climate were compared using exploratory and confirmatory factor analyses. Results indicated that peer justice climate is best conceptualized as having three dimensions (distributive, procedural, interactional) with an overarching justice factor connecting them. Suggestions are made for improving the measure. Procedural peer justice climate was found to have a significant positive relation with team performance.

Adaptive Perfectionism

The aim of the study was to examine the nature of perfectionism, to gain a better understanding of the construct using the Chinese population. The study also explored the relationships between perfectionism, self-esteem and depression after identifying the three dimensions of perfectionism. A sample of 292 Chinese university students completed the Frost Multidimensional Perfectionism Scale (FMPS), the Hewitt Multidimensional Perfectionism Scale (HMPS), the Almost Perfect Scale — Revised (APS-R), the Self-Esteem Scale (SES), and the Beck Depression Inventory (BDI). As hypothesised, the confirmatory factor analyses revealed that multidimensional perfectionism is explained as a three-factor construct with dimensions of maladaptive perfectionism, adaptive perfectionism and order factor. As predicted, the structural equation model analyses indicated that self-esteem partially mediated the relationship between maladaptive perfectionism and depression. Implications for counselling interventions and future research are discussed.

Development And Validation

Purpose Counterproductive work behaviour (CWB) is a type of behaviour of an individual that works against an organisation or employer, and he/she is usually discretionary (i.e. individuals make conscious choices as to whether they want to commit aberrant work behaviour). To deal with CWB in different contexts, organisations need to both understand and continually measure their employees in terms of behaviour and work. This study aims to develop an instrument to measure CWB for small and medium-sized enterprises in Thailand. Design/methodology/approach The study was conducted in three stages to develop a measurement scale for CWB. First, 27 questions were developed as a questionnaire based on concepts and theories of CWB and then verified using exploratory factor analysis with three CWB dimensions, namely “poor behaviour”, “misuse of organisational resources” and “inappropriate communication”. The questionnaire surveyed a total of 386 individuals working in SMEs. Finally, confirmatory factor analysis (CFA) and convergent validity were examined following the three CWB dimensions. Findings Three dimensions were developed to measure CWB, including aspects of poor behaviour, misuse of organisational resources and inappropriate communication. Practical implications The CWB questionnaire has practical use for assessing employee behaviour and can assist organisations and practitioners to better understand the CWB of employees. This know-how will help practitioners to assess employee behaviour and can be used to manage or develop this into good behaviour as valued members of the organisation. Originality/value The validity of the CWB questionnaire questions will facilitate the future research on the boundaries with CWB assessments spanning different SMEs contexts. Empirical study results validated that CWB measurement offered new perspectives to explore vital employee behavioural deviation that are necessary for the inspection employee behavioural deviation. This instrumental support will also help researchers to effectively understand CWB and explore its potential in future studies.

AbstractThis study presents the validation process of the Portuguese version of the short-form Dedication Scale (Rhoades, Stanley, & Markman, 2006; Stanley, 1986), with a sample of 924 participants in different relationship statutes. With 14 items, this short version is recommended by the authors for its simple use, when wanting to measure commitment in romantic relationships. Confirmatory factor analysis showed that the instrument did not have a totally acceptable fit with the data so an exploratory factor analysis was conducted. This revealed a one-dimensional structure of the scale, and led to the exclusion of two items, which relate to a distinct meta-commitment dimension. In sum, the Portuguese version (ECP - Personal Commitment Scale) has 12 items, with good internal consistency (α = .82), correlations item-total between .36 and .60, and good criteria validity (p < .001). Its use for research is therefore appropriate. In a second study, significant differences were found between the participants' four relationship statuses (dating non-cohabiting and cohabiting relationships, formal unions and marriage) (p < .001; η2p = .03). Results showed that married participants were more committed than those in a formal union, even when controlling for several relational and socio-demographic variables. No differences were found between cohabiting and non-cohabiting dating participants. Men reported higher levels of commitment than women (p < .001; η2p = .02). Implications and suggestions for future research are discussed.

Quantitative nondestructive imaging of structural properties of semiconductor layer stacks at the nanoscale is essential for tailoring the device characteristics of many low-dimensional quantum structures, such as ultrafast transistors, solid state lasers and detectors. Here it is shown that scanning nanodiffraction of synchrotron X-ray radiation can unravel the three-dimensional structure of epitaxial crystals containing a periodic superlattice underneath their faceted surface. By mapping reciprocal space in all three dimensions, the superlattice period is determined across the various crystal facets and the very high crystalline quality of the structures is demonstrated. It is shown that the presence of the superlattice allows the reconstruction of the crystal shape without the need of any structural model.
