Being Grateful: Does it Bring Us Closer? Gratitude, Attachment and Intimacy in Romantic Relationships

To date, little is known about the function of gratitude in romantic relationships. Being grateful has been demonstrated to provide a number of positive benefits for individuals; however, few studies have explored how grateful experiences may be beneficial in enhancing romantic relationships. This study explored the extent to which adult attachment moderates the relationship between dispositional gratitude and the experience of intimacy within romantic relationships. A greater disposition toward gratitude was expected to result in more frequent experiences of gratitude. It was also anticipated that experiences of gratitude would be associated with feelings of closeness. Participants ( n = 156) were required to be currently in a relationship of at least six months duration and completed a series of questionnaires assessing dispositional gratitude, attachment and emotional intimacy. Moderation analysis revealed that although a positive, weak correlation existed between dispositional gratitude and intimacy, attachment did not moderate this association. It was concluded that further investigation of the experience of gratitude is necessary to understand the function of gratitude in romantic relationships. Methods focusing on specific experiences of gratitude in romantic relationships, and the associated feelings of closeness experienced by each partner, may yield more conclusive findings and may provide support for therapeutic approaches focused on enhancing closeness between couples by increasing experiences of gratitude.
Fast Classification of Meat Spoilage Markers Using Nanostructured ZnO Thin Films and Unsupervised Feature Learning

This paper investigates a rapid and accurate detection system for spoilage in meat. We use unsupervised feature learning techniques (stacked restricted Boltzmann machines and auto-encoders) that consider only the transient response from undoped zinc oxide, manganese-doped zinc oxide, and fluorine-doped zinc oxide in order to classify three categories: the type of thin film that is used, the type of gas, and the approximate ppm-level of the gas. These models mainly offer the advantage that features are learned from data instead of being hand-designed. We compare our results to a feature-based approach using samples with various ppm level of ethanol and trimethylamine (TMA) that are good markers for meat spoilage. The result is that deep networks give a better and faster classification than the feature-based approach, and we thus conclude that the fine-tuning of our deep models are more efficient for this kind of multi-label classification task.
Interpersonal Narratives in Cognitive and Interpersonal Psychotherapies

The purpose of the current investigation was to explore the predictors of the frequency and completeness of interpersonal narratives in psychotherapy. Narratives were extracted from 548 sessions of 72 patients who received either cognitive (CT) or interpersonal therapy (IPT) for depression. Consistent individual differences in narrative frequency, length, completeness, and number of therapist words per narrative were found. IPT sessions contained significantly more narratives than CT sessions, and CT sessions contained a higher proportion of therapist words per narrative. The alliance was positively related to the number of patient words per narrative, and patients with more involved interpersonal styles elicited more therapist words per narrative. Expectations about the causes of depression and helpfulness of focusing on interpersonal issues in therapy influenced narrative frequency and completeness more in CT than in IPT. Ziel der hier beschriebenen Untersuchung war eine uberprufung des pradiktiven Char.
CSF Venous Fistulas in Spontaneous Intracranial Hypotension: Imaging Characteristics on Dynamic and CT Myelography.

OBJECTIVE The objective of this study is to describe the anatomic and imaging features of CSF venous fistulas, which are a recently reported cause of spontaneous intracranial hypotension (SIH). MATERIALS AND METHODS We retrospectively reviewed the records of patients with SIH caused by CSF venous fistulas who received treatment at our institution. The anatomic details of each fistula were recorded. Attenuation of the veins involved by the fistula was compared with that of adjacent control veins on CT myelography (CTM). Visibility of the CSF venous fistula on CTM and a modified conventional myelography technique we refer to as dynamic myelography was also compared. RESULTS Twenty-two cases of CSF venous fistula were identified. The fistulas were located between T4 and L1. Ninety percent occurred without a concurrent epidural CSF leak. In most cases (82%), the CSF venous fistula originated from a nerve root sleeve diverticulum. On CTM, the abnormal veins associated with the CSF venous fistula were seen in a paravertebral location in 45% of cases, centrally within the epidural venous plexus in 32%, and lateral to the spine in 23%. Differences in attenuation between the fistula veins and the control veins was highly statistically significant (p < 0.0001), with a threshold of 70 HU perfectly discriminating fistulas from normal veins in our series. When both CTM and dynamic myelography were performed, the fistula was identified on both modalities in 88% of cases. CONCLUSION CSF venous fistulas are an important cause of SIH that can be detected on both CTM and dynamic myelograph y and may occur without an epidural CSF leak. Familiarity with the imaging characteristics of these lesions is critical to providing appropriate treatment to patients with SIH.
Measuring Dental Caries in the Mixed Dentition by ICDAS

Caries has traditionally been assessed with WHO criteria including only obvious caries lesions. ICDAS has been developed to detect also the enamel caries lesions. This study aims to study caries and the associations of the number of caries lesions between the permanent and primary molars with ICDAS in the mixed dentition of the first and second grade primary school children. The clinical examinations of 485 children were conducted by four examiners with high reproducibility (inter- and intraexaminer kappas >0.9). The mean number of caries lesions—especially dentine caries—seemed to be higher in the second primary molars than in the first permanent molars. There were significant correlations between the number of lesions on occlusal and lingual surfaces between the primary and permanent molars. Enamel caries lesions, restorations, and caries experience did not increase according to age. Therefore, caries might be increasing in this population. As a conclusion, ICDAS recording seems to give appropriate information from the occurrence of caries lesions and its correlations between the primary and permanent teeth and surfaces.
Combining clinical practice and academic work in nursing: A qualitative study about perceived importance, facilitators and barriers regarding clinical academic careers for nurses in university hospitals.

AIMS AND OBJECTIVES To obtain in-depth insight into the perceptions of nurse academics and other stakeholders regarding the importance, facilitators and barriers for nurses combining clinical and academic work in university hospitals. BACKGROUND Combining clinical practice and academic work facilitates the use of research findings for high-quality patient care. However, nurse academics move away from the bedside because clinical academic careers for nurses have not yet been established in the Netherlands. METHODS This qualitative study was conducted in two Dutch university hospitals and their affiliated medical faculties and universities of applied sciences. Data were collected between May 2015 and August 2016. We used purposive sampling for 24 interviews. We asked 14 participants in two focus groups for their perceptions of importance, facilitators and barriers in nurses' combined clinical and academic work in education and research. We audiotaped, transcribed and thematically analysed the interviews and focus groups. RESULTS Three themes related to perceived importance, facilitators and barriers: culture, leadership and infrastructure. These themes represent deficiencies in facilitating clinical academic careers for nurses. The current nursing culture emphasises direct patient care, which is perceived as an academic misfit. Leadership is lacking at all levels, resulting in the underuse of nurse academics and the absence of supporting structures for nurses who combine clinical and academic work. CONCLUSIONS The present nursing culture appears to be the root cause of the dearth of academic positions and established clinical academic posts. RELEVANCE TO CLINICAL PRACTICE A culture change would require a show of leadership that would promote and enable combined research, teaching and clinical practice and that would introduce clinical academic career pathways for nurses. Meanwhile, nurse academics should collaborate with established medical academics for whom combined roles are mainstream, and they should take advantage of their established infrastructure for success.
How to fold graciously

Proteins are macromolecules which possess several unique properties. They are very large (containing 2,000 or more atoms) and complex. Their structures show no obvious regularity but a very subtle regularity is apparent upon close examination. We know from the fact that proteins may be crystallized and further from x-ray crystallography that each atom occupies a unique place in the relative 3dimensional space of the molecule. If we consider a protein containing 2,000 atoms with no structural restrictions, such a macromolecule would possess 6,000 degrees of freedom. We know, however, from x-ray studies and other techniques as well, that there are indeed certain structural restrictions in a polypeptide structure. For example, if we schematically indicate a polypeptide chain as in Figure 1, we find that the 6 atoms in each unit indicated by the dotted lines lie in a common plane. Considerations of such factors allow us to predict only 450
Bis(4-amino-3,5-di-2-pyridyl-1,2,4-triazole-κ2 N 1,N 5)diaquazinc(II) dinitrate

The asymmetric unit of the title compound, [Zn(C12H10N6)2(H2O)2](NO3)2, contains one-half of the complex molecule and one NO3 − anion. The ZnII ion displays a distorted tetragonal-pyramidal geometry with four N atoms from two chelating 4-amino-3,5-di-2-pyridyl-1,2,4-triazole (2-bpt) ligands in the basal plane and one water molecule occupying the apical site. Another water molecule at the opposite of the apical site has a weak interaction with the ZnII ion [Zn—O = 2.852 (5) Å]. The ZnII ion and the two water molecules lie on a twofold rotation axis. An extensive system of hydrogen bonds involving the NH2 groups of the 2-bpt ligands, water molecules and nitrate anions links all residues into a three-dimensional network.
Parental Psychological Distress, Parent - Child Relationship Qualities, and Child Adjustment: Direct, Mediating, and Reciprocal Pathways

Objective. The purpose of this study was to explicate the role of parenting qualities of acceptance, psychological autonomy, and firm control in the link between maternal and paternal psychological distress and youth adjustment problems. Design. A community sample of 277 families provided information about parental psychological distress, parenting qualities, and child adjustment via mother, father, and child questionnaire ratings. Results. Direct associations among the variables were consistent with predictions. Mediation processes were identified using structural equation modeling. Specifically, parental acceptance and psychological autonomy served as mediators of the association between parental psychological distress and child problems, whereas firm control did not mediate the direct associations. Conclusions. Drawing on a developmental psychopathology perspective, this study's results indicate that the link between mother and father psychological distress and child adjustment problems is accounted for, in part, by parental acceptance and psychological autonomy than by behavioral control. Alternative pathways among these family processes also received empirical support.
‘Something’s Gotta Give:’ Advanced-Degree Seeking Women’s Experiences of Sexism, Role Overload, and Psychological Distress

With the rise in advanced-degree seeking women and the minimal research on the dual impact of sexism and role overload, the current study aims to better understand the impact of sexism and role overload on psychological distress in a particular sample of advanced-degree seeking women. Seventy-six female medical student participants (mean age 24.7) from a southeastern health sciences university were recruited to participate in this study. Perceived sexist events were significantly correlated with depressive symptoms, with the exception of lifetime sexist events, anxious symptoms, and stress. Consistent with predictions, perceived sexist events were also positively correlated with role overload. In addition, role overload was positively correlated with psychological distress. Role overload was found to mediate the relationships between perceived sexist events and psychological distress in this sample, suggesting that it may impact psychological distress more than sexist events. Directions for future research and implications for women who experience sexism and role overload and who suffer from psychological distress are discussed.
7 Multidimensional Texture Analysis for Unsupervised Pattern Classification

Clustering techniques aim to regroup a set of multidimensional observations, represented as data points scattered through a N-dimensional data space, into groups, or clusters, according to their similarities or dissimilarities. Each point corresponds to a vector of observed features measured on the objects to be classified. Among the different approaches that have been developed for cluster analysis [Jain et al., 1999; Theodoridis & Koutroumbas, 2003; Tran et al., 2005; Xu & Wunsch, 2005; Filipone et al., 2008], we consider the statistical approach [Devijver & Kittler, 1983]. In this framework, many clustering procedures have been proposed, based on the analysis of the underlying probability density function (pdf). The high density of data points within the clusters gives rise to modal regions corresponding to the modes of the pdf that are separated by valleys of low densities [Parzen, 1962]. Independently from cluster analysis, a large amount of research effort is devoted to image segmentation. Starting from an unstructured collection of pixels, we generally agree about the different regions constituting an image due to our visual grouping capabilities. The most important factors that lead to this perceptual grouping are similarity, proximity and connectedness. More precisely, segmentation can be considered as a partitioning scheme such that: Every pixel of the image must belong to a region, The regions must be composed of contiguous pixels, The pixels constituting a region must share a given property of similarity. These three conditions can be easily adapted to the clustering process. Indeed, each data point must be assigned to a cluster, and the clusters must be composed of neighbouring data points since the points assigned to the same cluster must share some properties of similarity. Considering this analogy between segmentation and clustering, several image segmentation procedures based on the gray-level function analysis have been successfully adapted to detect the modes or to seek the valleys of the pdf for pattern classification purpose [BotteLecocq et al., 2007]. In this framework, the underlying pdf is generally estimated on a regular discrete array of sampling points [Postaire & Vasseur, 1982].

Two-parameter integral representation formula for the effective elastic moduli of two-phase composites

In this article, the integral representation formula (IRF) for the family of composites described in (1) is derived and the relation between moments of positive measures and the microstructure are established explicitly. This family represents composites consisting of one phase with fixed isotropic elasticity tensor and the other phase with varying elasticity tensor, e.g. viscoelastic materials whose complex-valued moduli change with frequency. Every choice of complex bulk modulus and shear modulus for constituent in Ω2 corresponds to a unique choice of parameters ξ1 and ξ2, the contrast between the bulk moduli and shear moduli, respectively. All choices with Im(ξ1) · Im(ξ2) > 0 have well-defined effective elasticity tensor C*(ξ1, ξ2). For each component of C* that can be obtained by ε 0 : C* : ε 0 with some real symmetric matrix ε 0, the Borel measure in the IRF is independent of the choice of (ξ1, ξ2); it is determined by the microstructure and the reference medium C (1). This implies that information of microstructure of the composites and the contrast of constituent properties are separated. Hence it potentially provides a way for retrieving microstructural information from measurement of C* of different (ξ1, ξ2) and C (1). The relation between the moments of the Borel measure and statistical information of the microstructure is established by first deriving the Taylor series expansion of C* near the homogeneous case ξ1 = ξ2 = 0 and then analytically extending it by using the IRF, which is valid for every choice of (ξ1, ξ2) ∈ U 2 or (−U)2.
Engineered Polymeric Hydrogels for 3D Tissue Models

Polymeric biomaterials are widely used in a wide range of biomedical applications due to their unique properties, such as biocompatibility, multi-tunability and easy fabrication. Specifically, polymeric hydrogel materials are extensively utilized as therapeutic implants and therapeutic vehicles for tissue regeneration and drug delivery systems. Recently, hydrogels have been developed as artificial cellular microenvironments because of the structural and physiological similarity to native extracellular matrices. With recent advances in hydrogel materials, many researchers are creating three-dimensional tissue models using engineered hydrogels and various cell sources, which is a promising platform for tissue regeneration, drug discovery, alternatives to animal models and the study of basic cell biology. In this review, we discuss how polymeric hydrogels are used to create engineered tissue constructs. Specifically, we focus on emerging technologies to generate advanced tissue models that precisely recapitulate complex native tissues in vivo.
Early Sensory Pathways for Detection of Fearful Conditioned Stimuli: Tectal and Thalamic Relays

Sensory stimuli acquire significance through learning. A neutral sensory stimulus can become a fearful conditioned stimulus (CS) through conditioning. Here we report that the sensory pathways used to detect the CS depend on the conditioning paradigm. Animals trained to detect an electrical somatosensory stimulus delivered to the whisker pad in an active avoidance task were able to detect this CS and perform the task when a reversible or irreversible lesion was placed in either the somatosensory thalamus or the superior colliculus contralateral to the CS. However, simultaneous lesions of the somatosensory thalamus and superior colliculus contralateral to the CS blocked performance in the active avoidance task. In contrast, a lesion only of the somatosensory thalamus contralateral to the same CS, but not of the superior colliculus, blocked performance in a pavlovian fear conditioning task. In conclusion, during pavlovian fear conditioning, which is a situation in which the aversive outcome is not contingent on the behavior of the animal, the sensory thalamus is a critical relay for the detection of the CS. During active avoidance conditioning, a situation in which the aversive outcome is contingent on the behavior of the animal (i.e., the animal can avoid the aversive event), the sensory thalamus and the superior colliculus function as alternative routes for CS detection. Thus, even from early stages of sensory processing, the neural signals representing a CS are highly distributed in parallel and redundant sensory circuits, each of which can accomplish CS detection effectively depending on the conditioned behavior.
Critical Assessment of Qualitative Research

T his special issue was developed in response to the increasing interest in qualitative research in occupational therapy. Since becoming Editor of The Occupational Therapy Journal of Research I have observed a substantial increase in the number of manuscripts with qualitative approaches submitted for editorial review. As Krefting (1991) pointed out, "models used to evaluate quantitative research are seldom relevant to qualitative research" (p.214). This issue of the Journal emerged from discussions with Jeffrey Gliner, PhD, regarding the need for continued discussion and assessment of evaluative criteria for critically reviewing qualitative research. "Too frequently, qualitative research is evaluated against criteria appropriate to quantitative research and is found to be lacking" (Krefting, 1991, p. 214). The criteria posed in Gliner's lead-off article and highlighted in the research studies included in this issue continue discussions already initiated by Hasselkus (1991), Krefting (1991), and others regarding obtaining and honing criteria for the assessment of qualitative research. Ultimately, this will enhance the rigor, trustworthiness, and quality of research published in our field. In The Occupational Therapy Journal of Research in 1982 Kielhofner pointed out the relevance of qualitative methodologies to occupa-
Quantitative X-ray Tomography of the Mouse Cochlea

Imaging with hard X-rays allows visualizing cochlear structures while maintaining intrinsic qualities of the tissue, including structure and size. With coherent X-rays, soft tissues, including membranes, can be imaged as well as cells making use of the so-called in-line phase contrast. In the present experiments, partially coherent synchrotron radiation has been used for micro-tomography. Three-dimensional reconstructions of the mouse cochlea have been created using the EM3D software and the volume has been segmented in the Amira Software Suite. The structures that have been reconstructed include scala tympani, scala media, scala vestibuli, Reissner's membrane, basilar membrane, tectorial membrane, organ of Corti, spiral limbus, spiral ganglion and cochlear nerve. Cross-sectional areas of the scalae were measured. The results provide a realistic and quantitative reconstruction of the cochlea.
Breast conservative surgery for operable invasive ductal carcinoma after neoadjuvant chemotherapy or hormonal therapy- a challenge for breast surgeon: a review based on literature and experience.

UNLABELLED Neoadjuvant chemotherapy or hormonal therapy is based on biological data and enables more patients to be treated with breast conserving surgery for locally advanced T2 and T3 without significantly increasing the rates of ipsilateral breast recurrence. Careful consideration of an optimal preoperative planning aims at accurately determining the patterns of primary tumour down staging and at the amount and location of any residual tumour in the breast, besides converting patients from mutilating surgery candidates to candidates for breast conservative procedure. The use of induction chemotherapy has the potential to improve the cosmetic results but free margins must be achieved and surgery must be planned in onco-plastic surgery. Axillary lymph node clearance is still the gold standard surgery in the treatment of the axilla. Sentinel lymph node biopsy can be done for clinically N0 patients but only in control trials.
