Spinoza's Concept of Substance and Attribute: A Reading of the Short Treatise

ABSTRACT

In the recent secondary literature on Ockham’s philosophy of mind, it has been debated whether Ockham proposed an externalist or an internalist view of the intentional contents of intuitive cognitions. It has also been debated whether Ockham only attributes intentional content to intuitive cognitions, or rather two different properties, i.e. a likeness and an intentional content. Intuitive cognitions can be roughly understood as perceptions. In this article I propose a different perspective for analysing both debates, that is, the perspective that concerns Ockham’s theory of reflexivity. Ockham defended the idea that one can reflexively cognize two different features of intuitive cognitions; namely, their similarity or likeness, and their intentional content. Ockham proposed different degrees and modes of reflexive cognition regarding these features.     

Validation of the French version of the Object Spatial Imagery and Verbal Questionnaire

IntroductionThe Object Spatial Imagery and Verbal Questionnaire (OSIVQ) measures individual differences in Visual-Verbal cognitive style and distinguishes between spatial and object visual imagery.ObjectiveThe aim of this study was to evaluate the psychometric properties of a French version of the OSIVQ.MethodSeven hundred fifty-two participants completed the French OSIVQ and 144 of them also completed a paper-and-pencil assessment to evaluate spatial imagery, object imagery and verbal abilities.ResultsPrincipal component analyses of the OSIVQ showed good internal construct validity. Results also revealed pronounced individual differences and a significant gender effect. Confirmatory factorial analyses gave support to a three-dimensional model of cognitive style. Furthermore, correlations were observed across the different dimensions of the questionnaire and specific paper-and-pencil tasks.ConclusionOur results highlight the good psychometric properties of the French version of the OSIVQ.     

Psychometric properties of the French version of the Teachers’ Sense of Efficacy Scale (TSES-12f)

IntroductionSelf-efficacy appears to be an important resource for teachers assessed by the Teachers’ Sense of Efficacy Scale (TSES; Tschannen-Moran & Woolfolk Hoy, 2001).ObjectiveThe current study aims to explore psychometric properties the TSES short form translated into French, taking account of teachers’ experience with special needs students.MethodA sample of 283 primary and secondary teachers completed the scale.ResultsResults of confirmatory factor analyses confirm the tridimensional structure of the scale, which shows satisfactory psychometric properties.ConclusionThe usefulness of this scale is discussed considering the context of inclusive education reforms, as well as the potential protective effect of self-efficacy for teachers.     

Dislocation arrangements and crystallographic characterization of deformation band in fatigued copper single crystal

This letter reveals the dislocation arrangements and crystallographic characterization of deformation bands (denoted DBII) in a copper single crystal fatigued at a high strain amplitude gamma_pl = 8 x 10^-3. The results show that the surface deformation morphology of the crystal displays the following features. (1) Primary slip bands (SBs) were formed after 2 x 10⁴ cycles and these carried a relatively homogeneous and small plastic strain. (2) Secondary slip bands did not operate during cyclic deformation. (3) Deformation bands (DBs) with a width of 50 mum were homogeneously distributed over the whole surface of the crystal and were perpendicular to the SBs. (4) Dislocation patterns within the SBs often consisted of irregular structures, which did not show a persistent feature. The results indicate that these SBs are not typical persistent slip bands (PSBs). (5) Within the DBII, the microstructure can be classified into two types. One type consists of regular 100% ladder-like parallel PSBs. The other type is full of dislocation walls parallel to DB direction, which have not been reported previously. By crystallographic analysis of the DBII, it is shown that the habit plane of the DBII should correspond to the (101) plane. Based on the observations above, it is suggested that the formation of DBII should be attributed to the local regularization of dislocation walls within primary slip bands.

The Effects of Textured Insoles on Cortical Activity and Quiet Bipedal Standing With and Without Vision: An EEG Study

Abstract

Wearing textured insoles (TIs) can reduce static postural sway, but the neurophysiological mechanisms by which these changes occur are not well understood. To address this issue, cortical activity was investigated in this study using electroencephalography (EEG) recordings from 19 scalp locations, in 15 healthy young adults (5 females; mean age = 27?±?4.09 years) during quiet bipedal standing, under different insole conditions (textured versus smooth), with and without vision. Compared to smooth insoles (SIs), TIs significantly reduced postural sway in two measures; anterior–posterior range and standard deviation. In the EEG data, whole-head analyses showed cortical activity in the upper alpha power band was significantly reduced for textured compared to SIs. Exploratory analyses revealed this effect was significant both with and without vision, and was more pronounced over the parietal, compared to central regions, and over central compared to frontal regions. This trend was observed in low alpha and theta bands, but the effect of insole type was not significant. Textured insoles thus appear to affect not only balance outcomes but also cortical activity. The cortical activity adaptation may represent greater information becoming readily available at the cortical level, enhancing the representation of the body in space.     

A new highly ordered Al-Ni-Ru decagonal quasicrystal with 1.6 nm periodicity

A new decagonal quasicrystal (the D phase) with a period of about 1.6 nm was found to form in conventionally solidified and heat-treated Al₇₅Ni₁₅Ru₁₀ alloys. The electron diffraction patterns of the Al-Ni-Ru D phase exhibit a large number of quite sharp diffraction spots located at precise decagonal symmetry positions, indicating a highly ordered decagonal quasicrystal with a long-range quasiperiodic correlation. The D phase is formed with a composition close to Al₇₄Ni₁₅Ru₁₁, as determined by energy-dispersive X-ray analysis. By means of high-resolution electron microscopy, the structural features of the Al-Ni-Ru D phase, which are obviously different from that of the Al-Pd D phase (a typical decagonal quasicrystal with 1.6 nm periodicity reported previously), have been revealed.     

Construction et validation d’une échelle de mesure des représentations sociales du travail informel

IntroductionReliable tools capable of assessing the various dimensions of the representations of informal work are inexistent. This very situation contributes in eliminating the possibilities of quantitative studies on informal work in psychology.ObjectiveThe objective of this study is to put forward a quantifying instrument of the representations of informal work, presenting adequate psychometric qualities.MethodThree case studies have been realized in Cameroon: the first one is qualitative, and enables the identification of considerable elements of the representations of informal work through proper analyses; the last two studies are quantitative. Data are collected with a questionnaire and analysed using exploratory and confirmatory factor analyses through SPSS17.0 and Amos.21 software.ResultsThree dimensions of representations of informal work arises from analyses: nature and security, normative aspects, financial aspects related to informal work. It is also noted that intentions to engage into the restructuring programmes of informal work are significantly oriented by the representations of informal work.ConclusionThus, the convenience of the scale once validated, its perspectives and its limits remain arguable.     

Defining features of unhealthy exercise associated with disordered eating and eating disorder diagnoses

ObjectivesThe current study sought to compare different features of unhealthy exercise on associations with disordered eating and their ability to identify individuals with eating disorders. A secondary aim of the study was to compare prevalence and overlap of different aspects of unhealthy exercise and potential differences in their gender distribution.DesignCross-sectional epidemiological study.MethodsA community-based sample of men (n = 592) and women (n = 1468) completed surveys of health and eating patterns, including questions regarding exercise habits and eating disorder symptoms.ResultsCompulsive and compensatory features of exercise were the best predictors of disordered eating and eating disorder diagnoses compared to exercise that was excessive in quantity. Further, compulsive and compensatory aspects of unhealthy exercise represented overlapping, yet distinct qualities in both men and women.ConclusionsIncluding the compulsive quality among the defining features of unhealthy exercise may improve identification of eating disorders, particularly in men. Results suggest that the compensatory aspect of unhealthy exercise is not adequately captured by the compulsive aspect of unhealthy exercise. Thus, interventions that target unhealthy exercise behaviors among high-risk individuals, such as athletes, may benefit from addressing both the compulsive and compensatory aspects of unhealthy exercise. Future prospective longitudinal studies will aid in determining the direction of the association between these features of unhealthy exercise and the onset of eating pathology.     

The Limits of Photography

Abstract

This paper is about what counts as a photograph and what does not. One way in which this question arises stems from new technologies that keep changing our way of producing photographs, such as digital photography, which not only has now widely replaced traditional film photography but also challenges the very limits of what we count as a photograph. I shall discuss below at some length different aspects of digital photography, but also want to focus here on a new striking type of photographic camera, announced in early 2012 by Lytro, Inc., namely, the so-called ‘Light Field Camera’, which is said to represent a revolution in the photographic world. Indeed, unlike in the case of any previously available cameras, the photographs produced by a Light Field Camera can be re-focused after the photograph has been taken, which harbours many interesting consequences with regard to the resulting image and the way we interact with it. But of course, the initial question also arises in the case of traditional film photography as well as ‘traditional’ digital photography. The question amounts to asking about what the essential features of photographs are – in short, what their nature is.     

Mystery,Values, and Meaning: Religious Options that Respect Science

Abstract

Human nature is a contested concept and notions of it vary across disciplines. Despite this diversity, three basic notions of human nature emerge. One identifies human nature with properties that are innate, hardwired or products of some kind of necessary essence. Another understands it as consisting of properties that make human unique or distinct from non-human animals. Finally, some seek human nature by attempting to identify universal or near-universal properties of humans. While the sciences might not give us a robust form of innate or hardwired human nature, “human nature” as a concept might still serve other, non-scientific, goals.     

Structure analysis of two-dimensional quasicrystals

Aperiodic materials, such as two-dimensional quasicrystalline structures, show characteristic elements in transmission electron microscopy images that are closely related to structure elements in the corresponding material. Although the arrangement of these structure elements fundamentally influences the properties of the two-dimensional quasicrystalline structures, it cannot be determined in a satisfactory way by conventional diffraction-based methods. We have developed an automated procedure for analysing images obtained by high-resolution transmission electron microscopy. The method, which is based on image processing, determines the two-dimensional arrangement of the characteristic features and enables subsequent statistical data analysis. It is illustrated with new tiling analyses of highly perfect decagonal Al-Co-Ni quasicrystals.     

The distressed (Type D) personality mediates the relationship between remembered parenting and psychological distress in cardiac patients

Objective: Both the distressed (Type D) personality (i.e. the combination of negative affectivity and social inhibition traits) and dysfunctional parenting styles are associated with anxiety and depression. As parenting styles have been related to personality development, dysfunctional parenting styles may also be associated with Type D personality. We examined whether remembered parenting was associated with anxiety and depression in cardiac patients and whether Type D personality mediated this relationship.

Methods: Our sample comprised 435 patients treated with percutaneous coronary intervention (PCI) and 123 patients with congestive heart failure (CHF). Patients completed the Hospital Anxiety and Depression Scale, Type D Scale (DS14), and Remembered Relationship with Parents (RRP¹⁰) scale.

Results: Remembered parenting was significantly associated with higher anxiety and depression levels and Type D personality. In multivariable linear regression analyses, Type D personality accounted for 25–29% of the variance in anxiety and 23–46% of the variance in depression, while remembered parenting was no longer significantly associated with these domains. Sobel tests and bootstrapping indicated that Type D personality mediated the relationship between remembered parenting and anxiety and depression.

Conclusion: Type D personality mediated the relationship between remembered parenting and anxiety and depression in both PCI and CHF patients.     

Mixed-valence impurity in a nanoscale particle

We consider a mixed-valence Anderson impurity with infinite U embedded into a small metallic particle. The nanosize of the system leads to discrete energy levels rather than to a continuum of energy eigenstates for the host. Using the Brillouin-Wigner approximation we show that the magnetic susceptibility, which arises from the van Vleck admixing of the magnetic configuration into the ground state, is only weakly affected by the finite spacing of energy levels, while the specific heat and the entropy display an exponential activation at low temperatures, that is have properties deviating from a Fermi liquid.     

Elementary Students’ Motivation to Read and Genre Preferences

Abstract

This study examines the psychometric properties of a reading motivation measure with a sample of upper elementary students in the United States (n?=?195). The research explores upper elementary students’ motivation to read, the amount/frequency of their reading in general, and their preferences for different text genres. Factor analyses support the validity and reliability of the SRQ-RM for upper elementary students in the United States, a tool not previously used with this population. This study also included a nuanced assessment of students’ genre preferences, which has implications for reading motivation and effective classroom instruction.     

How to address the caveat of avoiding direct contact: Reducing prejudice towards gay and lesbian people in five Balkan countries

ABSTRACT

In the Balkans, contact with gays and lesbians is typically hostile or avoided. Drawing from probability samples of young people from five Balkan countries (N = 1046), we examined whether it is possible to transfer the effects of contact with other marginalized outgroups (largest ethnic minority in every country, Roma, the extremely poor and physically disabled) to acceptance of gays and lesbians (secondary outgroup), and whether this relationship could be explained by attitude generalization and increased intergroup trust. Path analyses supported the secondary transfer effect: it confirmed that, while controlling for direct contact, contact with other marginalized groups was related to more acceptance of a secondary group; this relationship was mediated by trust. This was found across all primary groups in the combined samples, while the effect varied for different groups in country samples. The results add to the value of intergroup contact as a mean of prejudice-reduction.     

Type D personality and social relations in adults with diabetes: results from diabetes MILES – The Netherlands

Abstract

Objective: To examine whether individual differences in Type D personality (combination of negative affectivity (NA) and social inhibition (SI)) could explain heterogeneity in perceived social support and relationship adjustment (intimate partner relationship) among people living with diabetes.

Design: In the Diabetes MILES—The Netherlands survey, 621 adults with type 1 or type 2 diabetes (54% female, age: 56?±?14 years) completed measures of Type D personality (DS14), perceived social support and relationship adjustment. We used established DS14 cut-off scores to indicate Type D personality, high NA only, high SI only and reference groups.

Results: Participants from the Type D and NA only groups perceived lower levels of social support (Welch[3,259]?=?37.27, p?<?0.001), and relationship adjustment (Welch[3,191]?=?14.74; p?<?0.01) than those from the SI only and reference groups. Type D was associated with lower social support (lowest quartile; adjusted OR?=?8.73; 95%CI?=?5.05?～?15.09; p?<?0.001) and lower relationship adjustment (lowest quartile; adjusted OR?=?3.70; 95%CI?=?2.10?～?6.53; p?<?0.001). Type D was also associated with increased levels of loneliness.

Conclusion: Participants with Type D and participants with high NA only tend to experience less social support and less relationship adjustment. Type D personality was also associated with more loneliness. Experiencing lower social support and relationship adjustment may complicate coping and self-management in people with diabetes.     

Media representations of environmental issues: From scientific to political discourse

IntroductionThe media is considered to be a social agent that intervenes in the elaboration of social representations of environmental issues.ObjectiveThis research analyses media representations of environmental issues and how they have been constructed and transformed from the Rio Summit in 1992 to 2006. The authors adopted a constructionist approach based on the theory of social representations (Moscovici, 1961/1976) to describe the generation of information by the mass media.MethodA sample of 1039 news articles from two Spanish newspapers (La Vanguardia and El País) was analysed. The period of study ranged from the Rio Earth Summit to several years after the Johannesburg Summit (1992–2006), and the study analyses both the content and form of the environmental news.ResultsThis longitudinal study shows not only an increase in environmental news during the period of analysis but also an increased variety of themes addressed and represented. The results evidence significant urban problems in recent years. The environment has shifted from being associated with nature to being predominately associated with the urban environment.ConclusionThe results suggest that there has been a movement from scientific to political discourse and a change towards greater reflection and social recognition of the relevance of environmental issues.     

Secondary traumatic stress and adjustment in therapists who work with sexual violence survivors: the moderating role of posttraumatic growth

ABSTRACT

Due to their secondary exposure to the traumatic events disclosed by clients, therapists who work with sexual violence survivors are at risk of experiencing secondary traumatic stress. We examined whether the negative effects of secondary traumatic stress on therapist adjustment would be buffered by posttraumatic growth. Sixty-one therapists who work with sexual violence survivors completed measures of secondary traumatic stress, posttraumatic growth and a range of adjustment indicators. Hierarchical multiple regression analyses demonstrated that posttraumatic growth moderated the negative impact of secondary traumatic stress on therapist depression, anxiety, personal meaning and satisfaction with life. Posttraumatic growth sustained positive affect through a direct effects model only. This study provides support for the protective role of posttraumatic growth in adjustment to secondary traumatic stress.     

Widgets: A new set of parametrically defined 3D objects for use in haptic and visual categorization tasks

IntroductionMost research to date on human categorization ability has concentrated on the visual and auditory domains. However, a limited – but non-negligible – range of studies has also examined the categorization of familiar or unfamiliar (i.e., novel) objects in the haptic (i.e., tactile-kinesthetic) modality.ObjectiveIn this paper, we describe how we developed a new set of parametrically defined objects, called widgets, that can be used as 3D (or 2D) materials for haptic (or visual) categorization purposes.MethodWidgets are unfamiliar complex 3D shapes with an ovoid body and four types of elements attached to it (eyes, tail, crest, and legs). The stimulus set comprises 24 objects divided into four categories of six exemplars each (the files used for 3D printing are provided as Supplementary Material).ResultsWe also assessed and demonstrated the validity of our stimulus set by conducting two separate studies of haptic and visual categorization, involving participants of different ages: young adults (Study 1), and children and adolescents (Study 2). Results showed that humans can categorize our 3D complex shapes on the basis of both haptically and visually perceived similarities in shape attributes.ConclusionWidgets are very useful new experimental stimuli for categorization studies using 3D printing technology.
