The Centrality of Relationships for Pedagogy

Te Kotahitanga is a research and professional development project that seeks to reduce educational disparities between indigenous Māori students and their non-Māori peers in New Zealand secondary schools. While evidence of the impact of the project on teachers’ practice and the associated gains made by Māori students has been published previously, in order for the work of Te Kotahitanga to contribute to the broader educational research community, its pedagogical premises require empirical verification. To do so, we must first establish the validity of the pedagogical data by addressing two questions: (a) To what degree can the data gathered in the collaborative processes of Te Kotahitanga be used as a measure of pedagogical quality? and (b) Do these data support the foundational hypothesis of the project, that “extended family” relationships, as understood by Māori people when using the Māori term, whanaungatanga, are a central necessary component of overall pedagogical quality? This article provides an account of the context of this work then presents an analysis directed to these questions in turn. First, our analysis of the observational data gathered during the Te Kotahitanga professional development process is presented, followed by the measures that were developed for each of the main dimensions of pedagogy addressed in this work. Second, using these measures we present our analysis of the inter-relation among these dimensions of pedagogy to test the Whanaungatanga pedagogical thesis.
Distributed maximum power point tracking of photovoltaic arrays: Novel approach and system analysis

One of the major drawbacks of photovoltaic (PV) systems is represented by the effect of module mismatching and of partial shading of the PV field. Distributed maximum power point tracking (DMPPT) is a very promising technique that allows the increase of efficiency and reliability of such systems. Modeling and designing a PV system with DMPPT is remarkably more complex than implementing a standard MPPT technique. In this paper, a DMPPT system for PV arrays is proposed and analyzed. A dc and small-signal ac model is derived to analyze steady-state behavior, as well as dynamics and stability, of the whole system. Finally, simulation results are reported and discussed.
A Simplified Approach for the Molecular Classification of Glioblastomas

Glioblastoma (GBM) is the most common malignant primary brain tumors in adults and exhibit striking aggressiveness. Although GBM constitute a single histological entity, they exhibit considerable variability in biological behavior, resulting in significant differences in terms of prognosis and response to treatment. In an attempt to better understand the biology of GBM, many groups have performed high-scale profiling studies based on gene or protein expression. These studies have revealed the existence of several GBM subtypes. Although there remains to be a clear consensus, two to four major subtypes have been identified. Interestingly, these different subtypes are associated with both differential prognoses and responses to therapy. In the present study, we investigated an alternative immunohistochemistry (IHC)-based approach to achieve a molecular classification for GBM. For this purpose, a cohort of 100 surgical GBM samples was retrospectively evaluated by immunohistochemical analysis of EGFR, PDGFRA and p53. The quantitative analysis of these immunostainings allowed us to identify the following two GBM subtypes: the “Classical-like” (CL) subtype, characterized by EGFR-positive and p53- and PDGFRA-negative staining and the “Proneural-like” (PNL) subtype, characterized by p53- and/or PDGFRA-positive staining. This classification represents an independent prognostic factor in terms of overall survival compared to age, extent of resection and adjuvant treatment, with a significantly longer survival associated with the PNL subtype. Moreover, these two GBM subtypes exhibited different responses to chemotherapy. The addition of temozolomide to conventional radiotherapy significantly improved the survival of patients belonging to the CL subtype, but it did not affect the survival of patients belonging to the PNL subtype. We have thus shown that it is possible to differentiate between different clinically relevant subtypes of GBM by using IHC-based profiling, a method that is advantageous in its ease of daily implementation and in large-scale clinical application.
Representing World History in the 21st Century

Following open-ended methodology used in an earlier research by Liu et al., social representations of world history were assessed among university student samples in 12 countries: China, India, Russia, Brazil, Indonesia, East Timor, Turkey, Poland, Hungary, Ukraine, Spain, and Portugal. Findings confirmed that across cultures, transcending boundaries of political ideology, civilization age, or youthful statehood. (a) World history is represented as a story about politics and warfare, with World War II the most important event in history and Hitler its most influential individual. (b) Recency effects are pervasive in young adults' collective remembering, with events and figures from the past 100 years accounting for 72% and 78% of nominations on average. (c) Representations were primarily Eurocentric, with events and figures in Western societies accounting for 40% of nominations overall, but this is tempered by nationalism, especially in the prevalence of local heroes instrumental to the founding of the current state. The representational hegemony of the victorious Western powers of World War II is being challenged by negative evaluations of the American presidency following 9/11 (September 9) and the Iraq War, with George Bush Jr. perceived as more negative than Hitler in four out of six samples where they were both nominated as important. Results are interpreted within a theoretical framework of history and identity, where collective remembering of the past is dynamically interlinked to political issues of the present.
Youth Gangs and Troublesome Youth Groups in the United States and the Netherlands

A minority of adolescents are part of street-oriented groups in which illegal behaviour is common, groups that can be referred to as ‘youth gangs’ or ‘troublesome youth groups’. Such groups are a well-known phenomenon in the United States and recently have been reported in a number of European nations. Relatively few researchers, however, have endeavoured to explore such youth gangs from a comparative perspective. In this article, we examine characteristics of American and Dutch gangs and gang members. These cross-national comparisons are based on two school samples of 11-16-year-old youths in the USA (N = 5935) and the Netherlands (N = 1978). The students completed anonymous, self-administered questionnaires containing similar questions, which allow for comparison of Dutch and American adolescent experiences with youth gangs.
Ultrastructure of the coelom in the brachiopod Lingula anatina

The organization of the coelomic system and the ultrastructure of the coelomic lining are used in phylogenetic analysis to establish the relationships between major taxa. Investigation of the anatomy and ultrastructure of the coelomic system in brachiopods, which are poorly studied, can provide answers to fundamental questions about the evolution of the coelom in coelomic bilaterians. In the current study, the organization of the coelom of the lophophore in the brachiopod Lingula anatina was investigated using semithin sectioning, 3D reconstruction, and transmission electron microscopy. The lophophore of L. anatina contains two main compartments: the preoral coelom and the lophophoral coelom. The lining of the preoral coelom consists of ciliated cells. The lophophoral coelom is subdivided into paired coelomic sacs: the large and small sinuses (= canals). The lining of the lophophoral coelom varies in structure and includes monociliate myoepithelium, alternating epithelial and myoepithelial cells, specialized peritoneum and muscle cells, and podocyte‐like cells. Connections between cells of the coelomic lining are provided by adherens junctions, tight‐like junctions, septate junctions, adhesive junctions, and direct cytoplasmic bridges. The structure of the coelomic lining varies greatly in both of the main stems of the Bilateria, that is, in the Protostomia and Deuterostomia. Because of this great variety, the structure of the coelomic lining cannot by itself be used in phylogenetic analysis. At the same time, the ciliated myoepithelium can be considered as the ancestral type of coelomic lining. The many different kinds of junctions between cells of the coelomic lining may help coordinate the functioning of epithelial cells and muscle cells.
Reaching a Better Understanding of the Control of Bimanual Movements in Older Adults

The ability to interact skilfully with the environment is essential for independent living and therefore a critical factor for the aging population. Here we investigate the differences between young and older adults in a bimanual reaching task where the goal is to bring two objects together to the same location with a synchronous placement. Older (mean age 74) and young (mean age 20) adults were asked to pick up two spatially disparate objects, one in each hand, and bring them together to place them in one of three trays laid out in front of them from left to right. The results showed that the older adults were no more detrimentally affected than the young by asymmetric bimanual movements compared to symmetric ones, and both groups completed their movements in the same time. Nevertheless, compared to the young, the older adult group produced reaches characterised by higher peak velocities (although this effect was marginal), shorter hover times, and where the movement distance varied for each hand the scaling of the kinematic profile across the two limbs diverged from that found with younger participants. They then spent longer than the young in the final adjustment phase and during this phase they made more adjustments than the young, and as a result were more synchronous in terms of the final placement of the objects. It seems that the older adults produced reach movements that were designed to reach the vicinity of the tray quite rapidly, after which time they made discreet adjustments to their initial trajectories in order to exercise the precision necessary to place the objects in the tray. These findings are consistent with the idea that older adults have problems using online control (as they wait until they can fixate both objects before making adjustments).
Analysis of Interpersonal Meaning in Public Speeches—A Case Study of Obama’s Speech

This paper uses the opening speech given by president Obama at a prime time news conference commemorating his first 100th day in office as the sample and tries to explore how interpersonal meaning is achieved from the perspective of Functional Grammar and with the focus on mood, modal auxiliary, personal pronouns in pronoun system, and tense shift. The finding shows that Obama makes full use of the language to achieve his political purpose in his speech by using different devices to fulfill interpersonal meaning.
YOUNG CHILDREN, ATTACHMENT SECURITY, AND PARENTING SCHEDULES

The focus of a recent Family Court Review Special Issue on attachment, separation, and divorce included perspectives primarily from researchers in the Bowlby/Ainsworth tradition. A number of the authors made recommendations against overnight visits for very young children. I review conceptualizations and measures of attachment security as well as empirical findings. Currently the foundation to make general recommendations regarding overnight visits is inadequate. Caution is needed in using attachment measures in court evaluations and regarding restrictive legal presumptions and theoretical orientations. Custody and access evaluations and decisions need to apply scientifically sound principles to the individual characteristics of each case. Key Points for the Family Court Community: •Simple “yes” or “no” answers are inadequate regarding the question of overnight visits for young children. •Attachment security can change and is influenced by multiple factors over the life span. •There are important scientific, ethical, and cost factors when considering the possible use of attachment security measures in custody evaluation. •Scientific findings about how overnight visits affect young children are mixed and seem best explained by differences in parental characteristics and interactions. •Each case deserves decision-making based on careful reasoning, informed by scientific findings and the relevant individual circumstances.
Use of Polyvinyl Alcohol as a Solubility Enhancing Polymer for Poorly Water-Soluble Drug Delivery (Part 2)

The KinetiSol® Dispersing (KSD) technology has enabled the investigation into the use of polyvinyl alcohol (PVAL) as a concentration enhancing polymer for amorphous solid dispersions. Our previous study revealed that the 88% hydrolyzed grade of PVAL was optimal for itraconazole (ITZ) amorphous compositions with regard to solid-state properties, non-sink dissolution performance, and bioavailability enhancement. The current study investigates the influence of molecular weight for the 88% hydrolyzed grades of PVAL on the properties of KSD processed ITZ:PVAL amorphous dispersions. Specifically, molecular weights in the processable range of 4 to 18 mPa · s were evaluated and the 4-88 grade provided the highest AUC dissolution profile. Amorphous dispersions at 10, 20, 30, 40, and 50% ITZ drug loads in PVAL 4-88 were also compared by dissolution performance. Analytical tools of diffusion-ordered spectroscopy and Fourier transform infrared spectroscopy were employed to understand the interaction between drug and polymer. Finally, results from a 30-month stability test of a 30% drug loaded ITZ:PVAL 4-88 composition shows that stable amorphous dispersions can be achieved. Thus, this newly enabled polymer carrier can be considered a viable option for pharmaceutical formulation development for solubility enhancement.
Emotional Intelligence in a Hierarchical Relationship: Evidence for Frontline Service Personnel

Following a mediation theory between basic personality trait and performance evaluation, the present research argues trait emotional intelligence (EI) as a personality trait, and examines evidence for the existence of a hierarchical model between trait EI and service performance. A survey was administered to personnel within a large service organization in the Asia-Pacific region. A hierarchical regression analysis on the 152 valid responses confirmed the validity of the proposed hierarchical relationship leading to conclusions about the applicability of the findings in service settings. The study findings provide insights into EI research from the construct operationalization perspective, extending into the broader theoretical context.
An Empirical Study of Stressors among Multimedia University Students: A Case of MMU Malacca Campus

Stress has become an important issue in university environment as well as in the real society. Many scholars in the field of behavioral science have carried out extensive research on stress and its outcomes and concluded that the issues of stressor are needed more attention. Specifically, stress in academic institutions can stimulate both positive and negative consequences that were depending on some factor. The main objective of the study is to identify the highest types of stress among students. Secondly, the study will explore the relationship between identified stressors and successful factor of student. This study used the survey method where 216 respondents has respons to the questionnaires. The study was applied to diploma students of Multimedia University Malacca Campus. One of finding shows that 89.7 percents students experienced stress, and 10.3 percent student’s not experiencing stress. Using logistic regression test, the findings of the study indicates that there are many other factors influences students stress such teaching quality/relations with lecturers, financial and environmental (campus and administrative) of the students which is can give impact in students life. Investigating the different areas where stress occurs can help students learn ways to cope with their stress.
Haploscope: a tool for the graphical display of haplotype structure in populations

Patterns of linkage disequilibrium are often depicted pictorially by using tools that rely on visualizations of raw data or pairwise correlations among individual markers. Such approaches can fail to highlight some of the more interesting and complex features of haplotype structure. To enable natural visual comparisons of haplotype structure across subgroups of a population (e.g. isolated subpopulations or cases and controls), we propose an alternative visualization that provides a novel graphical representation of haplotype frequencies. We introduce Haploscope, a tool for visualizing the haplotype cluster frequencies that are produced by statistical models for population haplotype variation. We demonstrate the utility of our technique by examining haplotypes around the LCT gene, an example of recent positive selection, in samples from the Human Genome Diversity Panel. Haploscope, which has flexible options for annotation and inspection of haplotypes, is available for download at http://scheet.org/software.
Inhaled nitric oxide combined with prostacyclin and adrenomedullin in acute respiratory failure with pulmonary hypertension in piglets

Our aim was to evaluate if the combined inhalation of both nitric oxide (iNO) and aerosolized prostacyclin or iNO and adrenomedullin (ADM) is more effective in lowering pulmonary arterial pressure (PAP) and improving oxygenation than nitric oxide alone in an animal model with pulmonary hypertension (PH). Moreover, we studied the effect on pulmonary mechanics, surfactant activity, and pulmonary oxidative stress of the different treatments. Twenty‐eight piglets with acute lung injury induced by lung lavages with saline were randomized to receive nitric oxide, nitric oxide plus prostacyclin, nitric oxide plus ADM or saline, after. Dynamic compliance, tidal volume, and airway resistance were measured. Lung tissue oxidation was evaluated by measuring total hydroperoxide and advanced oxidation protein products in bronchial aspirate samples. Surface surfactant activity was studied using Capillary Surfactometer. Inhaled nitric oxide combined with prostacyclin or ADM was more effective than nitric oxide alone in lowering PAP and improving oxygenation. Nitric oxide alone or combined increased lung compliance and tidal volume, and decreased airway resistance. No effects on surfactant surface activity and lung tissue oxidation were observed. The treatment with nitric oxide alone or combined with prostacyclin or ADM were effective in decreasing mean PAP and improving oxygenation in a piglet model of PH. However, nitric oxide plus prostacyclin and nitric oxide plus ADM were more effective than nitric oxide alone. The combination of aerosolized prostacyclin and ADM with nitric oxide might have a role in the treatment of infants with PH refractory to nitric oxide alone. 2007;42:1048–1056. © 2007 Wiley‐Liss, Inc.
Talking heads synthesis from audio with deep neural networks

Talking heads synthesis with expressions from speech is proposed in this paper. Talking heads synthesis can be considered as a learning problem of sequence-to-sequence mapping, which consists of audio as input and video as output. To synthesize talking heads, we use SAVEE database which consists of videos of multiple sentences speeches recorded from front of face. Audiovisual data can be considered as two parallel sequential data of audio and visual features and it is composed of continuous value. Thus, audio and visual features of our dataset are represented by a regression model. In this research, the regression model is trained with long short-term memory (LSTM) by minimizing mean squared error (MSE). Then, audio features are used as input and visual features are used as target of LSTM. Thereby, talking heads are synthesized from speech. Our method is proposed to use lower level audio features than phonemes and it enables to synthesize talking heads with expressions while existing researches which use phonemes as audio features only can synthesize neutral expression talking heads. With SAVEE database, we achieved the minimum MSE 17.03 on our testing dataset. In experiment, we use mel-frequency cepstral coefficient (MFCC), AMFCC and A2 MFCC with energy as audio feature and active appearance model (AAM) on entire face region as visual feature.
Child and Adolescent Psychopathy

This review paper discusses the construct of child and adolescent psychopathy and outlines controversy about the topic as well as some of the reasons that it might be developmentally appropriate. Past research has suggested that child psychopathy may be inapplicable to youth because the symptoms cannot be reliably distinguished from features of normative adolescent development. Concerns have also been raised regarding the possibility that the syndrome does not closely resemble the adult construct of psychopathy. We conclude that there is some truth to both sides of this story. Research shows that child psychopathy has a considerable degree of reliability and construct validity; however, there are also some important developmental differences. Furthermore, emerging evidence indicates potential changes in psychopathic symptoms over time and the important role of protective factors. Although, current research suggests that the concept of child psychopathy may be like an impressionist painting (i.e., clearer from a distance but messier as one gets closer), we argue this is not necessarily problematic from a developmental perspective. However, we conclude that a rigorous set of research studies will be needed to further advance our understanding of child psychopathy and the way it manifests itself over time.
‘It is a horrible term for someone’: service user and provider perspectives on ‘personality disorder’

This paper presents findings from a study exploring the views of people with personality disorder diagnoses and various professionals working with them. After outlining the policy context and the study’s conceptual framework, the aims and methods are described. Interviews were conducted with 12 service providers and 10 users. The main findings are then discussed, including user and provider perspectives on the meaning of ‘personality disorder’ and the strategies and support people use to address their difficulties. Finally, the theoretical implications of the findings are discussed.
Zimbabwean Teachers’ Attitudes Towards the Integration of Pupils with Disabilities into Regular Classrooms

Integration of pupils with disabilities whenever possible is official educational policy in Zimbabwe. This paper reports results of surveys administered in 1989 and 1990 to 197 Zimbabwean teachers attending the University of Zimbabwe for advanced training. The results showed that levels of acceptance of the idea of integration are low and that attitudes are not unitary but rather depend upon what is being queried. Specifically, they show a clear preference ranking by type of impairment, and they differ depending upon whether their own classroom or classrooms in general are being asked about. Open‐ended questions provided more detail, supported the hierarchy of acceptance found in the closed‐ended questions and indicated that some teachers’ responses were extremely inappropriate.
