The Ball Welding Bar: A New Solution for the Immediate Loading of Screw-Retained, Mandibular Fixed Full Arch Prostheses
Authors: Bacchiocchi Danilo , Guida Andrea
Published: August 2017

Purpose. To present a new intraoral welding technique, which can be used to manufacture screw-retained, mandibular fixed full-arch prostheses. Methods. Over a 4-year period, all patients with complete mandibular edentulism or irreparably compromised mandibular dentition, who will restore the masticatory function with a fixed mandibular prosthesis, were considered for inclusion in this study. The “Ball Welding Bar” (BWB) technique is characterised by smooth prosthetic cylinders, interconnected by means of titanium bars which are adjustable in terms of distance from ball terminals and are inserted in the rotating rings of the cylinders. All the components are welded and self-posing. Results. Forty-two patients (18 males; 24 females; mean age 64.2±6.7 years) were enrolled and 210 fixtures were inserted to support 42 mandibular screw-retained, fixed full-arch prostheses. After two years of loading, 2 fixtures were lost, for an implant survival rate of 97.7%. Five implants suffered from peri-implant mucositis and 3 implants for peri-implantitis. Three of the prostheses (3/42) required repair for fracture (7.1%): the prosthetic success was 92.9%. Conclusions. The BWB technique seems to represent a reliable technique for the fabrication of screw-retained mandibular fixed full-arch prostheses. This study was registered in the ISRCTN register with number ISRCTN71229338.
Multihopping Multilevel Clustering Heterogeneity-Sensitive Optimized Routing Protocol for Wireless Sensor Networks
Authors: Aslam Muhammad , Wang Fan , Hu Xiaopeng , Asad Muhammad , Munir Ehsan Ullah
Published: August 2017

Effective utilization of energy resources in Wireless Sensor Networks (WSNs) has become challenging under uncertain distributed cluster-formation and single-hop intercluster communication capabilities. So, sensor nodes are forced to operate at expensive full rate transmission power level continuously during whole network operation. These challenging network environments experience unwanted phenomena of drastic energy consumption and packet drop. In this paper, we propose an adaptive immune Multihopping Multilevel Clustering (MHMLC) protocol that executes a Hybrid Clustering Algorithm (HCA) to perform optimal centralized selection of Cluster-Heads (CHs) within radius of centrally located Base Station (BS) and distributed CHs selection in the rest of network area. HCA of MHMLC also produces optimal intermediate CHs for intercluster multihop communications that develop heterogeneity-aware economical links. This hybrid cluster-formation facilitates the sensors to function at short range transmission power level that enhances link quality and avoids packet drop. The simulation environments produce fair comparison among proposed MHMLC and existing state-of-the-art routing protocols. Experimental results give significant evidence of better performance of the proposed model in terms of network lifetime, stability period, and data delivery ratio.

Published: August 2017

Background and Study Aims. GAVE is an uncommon cause of upper nonvariceal bleeding and often manifests itself as occult bleeding with chronic anemia. To date, the standard of care for GAVE is endoscopic treatment with thermoablative techniques. Despite good technical results, approximately two thirds of patients remain dependent on transfusions after the therapy. One of the emerging and more promising endoscopic treatments for GAVE is radiofrequency ablation (RFA). The aim of this study is to perform a systematic review of literature in order to assess current evidence supporting the effectiveness of this technique for treatment of refractory GAVE.Materials and Methods. Through electronic search, we identified 14 records, and after removal of duplicates and irrelevant studies, we selected 10 studies on radiofrequency ablation of GAVE: 4 prospective open-label single-center studies, 1 retrospective multicentric study, and 5 case reports.Results. Among all 72 treated patients reported in literature, 74.3% achieved a clinical response, while nonfatal AEs have been reported in 4.2% of cases.Conclusions. Despite some qualitative limitations, all literature data support effectiveness of RFA for treatment of refractory GAVE. In the future, large prospective controlled trials with adequate follow-up are needed to better assess the effectiveness and safety of this procedure.
Case Report of First Angiography-Based On-Line FFR Assessment during Coronary Catheterization
Authors: Kornowski Ran , Vaknin-Assa Hana
Published: August 2017

Fractional flow reserve (FFR), an index of the hemodynamic severity of coronary stenoses, is derived from hyperemic pressure measurements and requires a pressure-monitoring guide wire and hyperemic stimulus. Although it has become the standard of reference for decision-making regarding coronary revascularization, the procedure remains underutilized due to its invasive nature. FFRangio is a novel technology that uses the patient’s hemodynamic data and routine angiograms to generate a complete three-dimensional coronary tree, with color-coded display of the FFR values at each point along the vessels. After being proven to be as accurate as invasive FFR measurements in an off-line study, this case report presents the first on-line application of the system in the catheterization lab. Here too, a high concordance between FFRangio and invasive FFR was observed. In light of the demonstrated capabilities of the FFRangio system, it should emerge as an important tool for clinical decision-making regarding revascularization in patients with coronary artery disease.

Published: August 2017

The present study was aimed at evaluating the effect of a sea buckthorn (Hippophae rhamnoidesL.) fruit extract on selected quality properties of cooked sausages. The ethanolic extract of sea buckthorn fruit (SBE) incorporated at the highest level (3%) significantly affected the pH, weight losses, and instrumental color parameters of sausages. The SBE deteriorated organoleptic properties of sausages like juiciness, overall appearance, texture, and taste; however the sausages manufactured with 1.5% SBE were scored higher for color and almost the same as control for smell acceptance. Textural parameters like hardness, springiness, gumminess, and chewiness of cooked sausages decreased along with SBE addition. After 28 days of storage, the samples with 1.5% SBE addition were as springy, hard, and gummy as the control ones. Incorporation of SBE increased the shelf life of sausages. The highest inhibition of lipid oxidation was observed in the samples manufactured with 1.5% SBE. The SBE significantly improved the microbial qualities of sausages.

Authors: Alekseevich Aniskin Nikolay , Sergeevich Antonov Anton
Published: August 2017

Statement of the Problem. The article describes the problem of combined thermal-seepage regime for earth dams and those operated in the permafrost conditions. This problem can be solved using the finite elements method based on the local variational formulation.Results. A thermal-seepage regime numerical model has been developed for the “dam-foundation” system in terms of the tailings dam. The effect of heat-and-mass transfer and liquid phase transition in soil interstices on the dam state is estimated. The study with subsequent consideration of these factors has been undertaken.Conclusions. The results of studying the temperature-filtration conditions of the structure based on the factors of heat-and-mass transfer and liquid phase transition have shown that the calculation results comply with the field data. Ignoring these factors or one of them distorts the real situation of the dam thermal-seepage conditions.
A Multicriteria Approach to Find Predictive and Sparse Models with Stable Feature Selection for High-Dimensional Data
Authors: Bommert Andrea , Rahnenführer Jörg , Lang Michel
Published: August 2017

Finding a good predictive model for a high-dimensional data set can be challenging. For genetic data, it is not only important to find a model with high predictive accuracy, but it is also important that this model uses only few features and that the selection of these features is stable. This is because, in bioinformatics, the models are used not only for prediction but also for drawing biological conclusions which makes the interpretability and reliability of the model crucial. We suggest using three target criteria when fitting a predictive model to a high-dimensional data set: the classification accuracy, the stability of the feature selection, and the number of chosen features. As it is unclear which measure is best for evaluating the stability, we first compare a variety of stability measures. We conclude that the Pearson correlation has the best theoretical and empirical properties. Also, we find that for the stability assessment behaviour it is most important that a measure contains a correction for chance or large numbers of chosen features. Then, we analyse Pareto fronts and conclude that it is possible to find models with a stable selection of few features without losing much predictive accuracy.

Published: August 2017

Exogenous progesterone has several applications in human health and in veterinary medicine, especially in fixed-time artificial insemination protocol. Progesterone nanoencapsulation in biocompatible polymers, such as poly(methyl methacrylate) (PMMA), is an alternative to substitute silicone-based release device traditionally used for estrus control. Progesterone concentration inside the nanoparticles must be precisely known; for that reason, a validation methodology must be applied to ensure reliable results, suitable for nanoparticles application. In this work, an UV-Vis spectrophotometric method was validated for the determination of progesterone in PMMA nanoparticles synthesized by miniemulsion polymerization. Chloroform was used as solvent, showing selectivity to the encapsulated drug and the components of the polymeric matrix did not influence progesterone recovery. Detection and quantitation limits (DL and QL) obtained were 0.32 and 0.96 mg·L−1, respectively, and precision tests (between different analysts and equipment) indicated acceptable Relative Standard Deviations (RSD < 5%). Miniemulsion polymerization reactions were carried out producing two different morphologies: nanospheres (NS) and nanocapsules (NC), with average intensity diameters (Dz) of 150–200 nm and 240–300 nm, respectively. Polymerization gravimetric conversions obtained for both cases were higher than 95% and encapsulation efficiencies greater than 69% and 90% for the nanospheres and nanocapsules, respectively.
Orthogonal Signal Correction to Improve Stability Regression Model in Gas Sensor Systems
Authors: Laref Rachid , Ahmadou Diaa , Losson Etienne , Siadat Maryam
Published: August 2017

Metal oxide sensors are the most often used in electronic nose devices because of their high sensitivity, long lifetime, and low cost. However, these sensors suffer from a lack of response stability making the electronic nose systems useless in industrial applications. The sensor instabilities are particularly caused by incomplete recovery process producing gradual drifts in the sensor responses. This paper focuses on a signal processing method combining baseline manipulation and orthogonal signal correction technique in order to reduce effectively the drift impact from the sensor outputs. The proposed signal processing is explored using experimental data obtained from a gas sensor array responding to various concentrations of pine essential oil vapors. Partial Least Square method is then applied on the corrected dataset to establish a regression model for the estimation of gas concentration. In this work, we show essentially how our drift correction approach can help to improve significantly the stability of the regression model, while ensuring good accuracy.

Published: August 2017

Gastric adenocarcinoma is the third leading cause of cancer-related death worldwide, but no models exist to readily investigate distant metastases that are mainly responsible for mortality in this disease. Here we report the development of a genetically engineered mouse model of gastric adenocarcinoma tumorigenesis based on KrasG12D expression plus inactivation of E-cadherin (Cdh1) and p53 in the gastric parietal cell lineage. Intestinal and diffuse gastric tumors arise rapidly in this model that displays a median survival of 76 days. Tumors occur throughout the stomach, with metastases documented in lymph nodes, lung, and liver. Mice otherwise identical but retaining one wild-type Cdh1 allele exhibited longer survival with only 20% penetrance of invasive tumors and no apparent lung or liver metastases. Notably, increased RAS activity and downstream MAPK signaling was observed in stomachs only when E-cadherin was absent. This model offers a valuable tool to investigate gastric adenocarcinoma subtypes where RAS/MAPK pathway activation and E-cadherin attenuation are common. Cancer Res; 77(19); 5349–59. ©2017 AACR.

Published: July 2017

In prostate cancer, androgen deprivation therapy (ADT) enhances the cytotoxic effects of radiotherapy. This effect is associated with weakening of the DNA damage response (DDR) normally supported by the androgen receptor. As a significant number of patients will fail combined ADT and radiotherapy, we hypothesized that DDR may be driven by androgen receptor splice variants (ARV) induced by ADT. Investigating this hypothesis, we found that ARVs increase the clonogenic survival of prostate cancer cells after irradiation in an ADT-independent manner. Notably, prostate cancer cell irradiation triggers binding of ARV to the catalytic subunit of the critical DNA repair kinase DNA-PK. Pharmacologic inhibition of DNA-PKc blocked this interaction, increased DNA damage, and elevated prostate cancer cell death after irradiation. Our findings provide a mechanistic rationale for therapeutic targeting of DNA-PK in the context of combined ADT and radiotherapy as a strategy to radiosensitize clinically localized prostate cancer.

miR-432 Induces NRF2 Stabilization by Directly Targeting KEAP1
Authors: Akdemir Burak , Nakajima Yasuaki , Inazawa Johji , Inoue Jun
Published: August 2017

NF-E2–related factor 2 (NRF2) is a master transcriptional regulator that integrates cellular stress responses and is negatively regulated by Kelch-like ECH-associated protein 1 (KEAP1) at the post-translational level. In human cancers, aberrantly stabilized NRF2, by the mutation of either NRF2 or KEAP1 or by the potential inhibition of autophagy, plays a vital role in tumor growth and chemoresistance through the activation of target genes. MicroRNAs (miRNA) are endogenous small noncoding RNAs that can negatively regulate gene expression by interfering with translation and/or stability of target transcripts. However, miRNA-mediated regulation of the NRF2–KEAP1 pathway under physiological conditions is poorly understood. Here, miR-432-3p positively regulates NRF2 activity through the downregulation of KEAP1 by a direct-binding mechanism to the coding region of KEAP1. Overexpression of miR-432-3p resulted in a decreased sensitivity of esophageal squamous cell carcinoma (ESCC) cells to chemotherapy drugs including cisplatin (CDDP). Conversely, the inhibition of miR-432-3p expression by the CRISPR/Cas9 system resulted in an increased sensitivity of ESCC cells to CDDP. Furthermore, miR-432-3p was overexpressed in primary ESCC tumors (55 of 84, 65.5%) and a negative correlation between the expression level of KEAP1 and miR-432-3p in primary ESCC tumors was observed.

Implications: These findings provide novel insights into the mechanism of NRF2 stabilization in human cancers. Mol Cancer Res; 15(11); 1570–8. ©2017 AACR.

Authors: Costa Cristiane de Souza , Ferreira Joaquim Mendes , Lima Neto Heleno Carlos de , Bezerra Francisco Hilário Rego , Sousa Maria Osvalneide Lucena
Published: August 2017

A atividade sísmica em Pedra Preta (RN), localizada no Nordeste do Brasil, região de maior sismicidade intraplaca do país, teve início em dezembro de 2010. Antes disso, não havia registro de sismos na área. Durante o ano de 2013 e início de 2014, a rede sismográfica de Pedra Preta registou 273 sismos locais em 3 ou mais estações. Desses eventos foram selecionados os 50 com melhor leitura dos tempos de chegada das ondas P e S, sendo determinado o modelo de velocidades (Vp/Vs = 1,72 e Vp = 5,90 km/s) e calculados os hipocentros, com o programa HYPO71. Para a determinação do mecanismo focal composto foi realizada uma nova seleção de sismos obedecendo critérios mais restritos para os hipocentros (epicentros localizados dentro da rede com resíduo médio de tempo de chegada ≤ 0,01 s, número de observações ≥ 10, erro médio na horizontal < 0,1 km, erro médio na vertical < 0,1 km), tendo sido selecionados por esses critérios 24 eventos. Os hipocentros desses sismos mostram que a falha sismogênica tem aproximadamente 3 km de extensão, com sismos de 2,3 a 5,8 km de profundidade. Os parâmetros da falha sismogênica foram obtidos pela combinação do método dos mínimos quadrados e do programa FPFIT (strike = 254º, dip = 67º e rake = -66º), caracterizando uma falha normal. Os epicentros e o mecanismo focal foram utilizados para verificar se havia ou não possível correlação com feições geológicas mapeadas na área. A conclusão é que não existem feições geológicas mapeadas que possam estar relacionadas diretamente com a atividade sísmica estudada.

Published: August 2017

Este artigo apresenta a criação de um depósito mineral sintético de cobre e a verificação de sua adequação para a avaliação de métodos geoestatísticos, uma vez que é possível comparar os resultados obtidos com os valores reais. Essa verificação foi realizada a partir da amostragem do depósito. A criação desse tipo de modelo é essencial à quantificação da qualidade de métodos geoestatísticos, na mineração isso é inviável, pois nem exaurindo a mina é possível conhecer completamente o depósito. O modelo sintético criado é baseado em um modelo de depósito mineral real mineralizado a cobre, com geologia e distribuições estatística e espacial heterogêneas. O modelo reproduz um depósito com preenchimento hidrotermal de uma falha inversa e as rochas encaixantes são meta-arenitos e folhelhos dobrados. A distribuição espacial foi criada por simulação sequencial gaussiana não condicional. A amostragem do depósito sintético foi realizada na forma de sondagens com separação entre furos de aproximadamente 40 m para norte e para leste. Os furos de sonda têm direção e mergulho de aproximadamente 270/45. A análise geoestatística e a simulação estocástica foram calculadas nessa base de dados. As comparações com relação ao modelo do depósito foram realizadas pelo confronto das estatísticas descritivas dos resultados com aquelas amostrais e também com os parâmetros estatísticos do modelo sintético, além de gráficos do tipo Q-Q para comparar as distribuições derivadas da simulação com a distribuição populacional do depósito. Concluiu-se que a criação do depósito foi satisfatória, visto que os resultados obtidos por uma técnica de simulação reconhecidamente eficiente foram coerentes.

Background and Purpose—

Many guidelines for secondary prevention of stroke focus on controlling cardiometabolic risk factors. We investigated the effectiveness of a management program for attaining cardiometabolic targets in survivors of stroke/transient ischemic attack.

Methods—

Randomized controlled trial of survivors of stroke/transient ischemic attack aged ≥18 years. General practices were randomized to usual care (control) or an intervention comprising specialist review of care plans and nurse education in addition to usual care. The outcome is attainment of pre-defined cardiometabolic targets based on Australian guidelines. Multivariable regression was undertaken to determine efficacy and identify factors associated with attaining targets.

Results—

Overall, 283 subjects were randomized to the intervention and 280 to controls. Although we found no between-group difference in overall cardiometabolic targets achieved at 12 months, the intervention group more often achieved control of low-density lipoprotein cholesterol (odds ratio, 1.97; 95% confidence interval, 1.18–3.29) than controls. At 24 months, no between-group differences were observed. Medication adherence was ≥80% at follow-up, but uptake of lifestyle/behavioral habits was poor. Older age, being male, being married/living with partner, and having greater functional ability or a history of diabetes mellitus were associated with attaining targets.

Conclusions—

The intervention in this largely negative trial only had a detectable effect on attaining target for lipids but not for other factors at 12 months or any factor at 24 months. This limited effect may be attributable to inadequate uptake of behavioral/lifestyle interventions, highlighting the need for new or better approaches to achieve meaningful behavioral change.

Is There a Hierarchical Relationship between Natural Prolongation and Distance in the Continental Shelf Delimitation?
Authors: Liao Xuexia
Published: August 2017

If a coastal State claims a continental shelf beyond 200 nautical miles (nm) that intrudes into the 200-nm limit of another State, the problem arises as to whether there is a hierarchical relationship between natural prolongation and distance, the two criteria of entitlement to the continental shelf provided by Article 76 of the un Convention on the Law of the Sea. A positive answer would mean that the continental shelf beyond 200 nm cannot encroach upon the 200-nm limit, otherwise there would be an area of overlapping entitlements which calls for maritime delimitation. This article attempts to analyse this problem from the perspectives of Article 76, relevant judicial cases, State practice, and the relationship between the regimes of the continental shelf and the Exclusive Economic Zone. It is submitted that the law is not conclusive, though a majority of coastal States tend to adopt a self-constraint approach. In addition, this problem brings further challenges to the law of maritime delimitation.
Preface to the Compendium of People-Saving Prescriptions Made with Native Korean Herbs
Authors: Kang Yeonseok , Kim Jaehyun
Published: August 2017

We can find several characteristics of Native Korean Herbal Medicine in the Preface of Compendium of People-Saving Prescriptions Made with Native Korean Herbs (Hyangyak Chesaeng Chipsŏngbang 鄕藥濟生集成方). First, it clarifies that saving people through medicine is part of the Neo-Confucianist ideal of ruling. Second, it emphasises that Korea’s medical tradition treats one disease with one herb, making it highly effective. Third, it points out that Korea is geographically different from China, and that treating disease with native Korean herbs has a faster and better effect than using foreign herbs. The geographic concept of Native Korean Herbal Medicine was inherited by the Treasured Mirror of Eastern Medicine (Tongŭi Pogam 東醫寶鑑) and had been the core idea of Chosŏn medicine until the early twentieth century.
Video Activists from Aleppo and Raqqa as ‘Modern-Day Kinoks’?
Authors: Wessels Josepha Ivanka
Published: August 2017

The popular uprising that began in Syria in 2011 generated an unprecedented number of YouTube videos recording events in Syria; this emphasized how the social media platform had become an important alternative space for news and information, a space beyond the control of the government. In this article, I address the role of Syrian video activism in the Syrian revolution, and pay particular attention to why young Syrian anti-regime protesters started recording and uploading their videos on YouTube. As such, I do not focus on technology or the medium per se, but on the peoples’ motivations—what led them to upload digital video content as testimonies of revolutionary events and violence. Based on observation of verified YouTube clips, field visits to Turkey and Syria and semi-structured interviews with Syrian video activists between the years 2014 and 2016, I suggest that Syrian video activists can be seen as revolutionary filmmakers similar to the twentieth-century ‘Kinoks’, or kino-ki, that formed part of Dziga Vertov’s Soviet filmmakers collective whose radical experiment aimed to bridge social revolution and realist cinematic practice (Tomas 1992) and document reality ‘As It Is’.
Where Is China Headed? New Tendencies in the Humanities and Social Sciences
Authors: Wang Xuedian
Published: August 2017

China as a whole is facing a marked trend toward indigenization. The past thirty years have seen rapid and profound changes in the social sciences, heralding a new season in the humanities, in which the study of traditional culture has shifted from the sidelines to the center of academic research. Traditional culture, especially Confucianism, with its worldly orientation, is bound to play a central role in deepening and expanding the ongoing conversation with liberalism. At the same time, however, it must still develop values for structuring society and everyday life that are as influential as those of liberalism. The three main challenges to a Confucian revival today are the ruling ideology in China (namely, Marxism), the dominance of Western sociopolitical theory, and the current practices of disciplinary organization.

Ixion Alderslade, 2001 and Ixioninae Alderslade, 2001 (Coelenterata: Octocorallia: Xeniidae): correctio errorum
Authors: ALDERSLADE PHILIP , JANES MICHAEL
Published: August 2017

In 2001 a Festschrift was published in the Bulletin of the Biological Society of Washington to honour Frederick (Ted) Bayer, preeminent octocoral taxonomist and Zoologist Emeritus of the Smithsonian Institution, on his 80th birthday. The volume was edited by Stephen Cairns and Charles Messing and contained papers and articles by many of Bayer’s colleagues and past students. The contents included a paper by the first author (Alderslade 2001), within which a number of new genera were described and a new xeniid subfamily was proposed. Not long after the volume was published a nomenclatural problem in the paper was brought to the attention of the first author. Sometime after this a second problem became apparent; one of imperfect technique that also has nomenclatural implications. Despite good intentions for prompt action to correct the situation, the task slipped furtively into the first author’s “must-not-forget-to-do-that” receptacle: a container already over-full and seemingly with very limited attention-holding ability, all too easy to blame on “Busy Life Syndrome” (Miriam R.). This very belated note finally addresses the nomenclatural issues.

More Frequent Sudden Stratospheric Warming Events due to Enhanced MJO Forcing Expected in a Warmer Climate
Authors: Kang Wanying , Tziperman Eli
Published: August 2017

Sudden stratospheric warming (SSW) events influence the Arctic Oscillation and midlatitude extreme weather. Observations show SSW events to be correlated with certain phases of the Madden–Julian oscillation (MJO), but the effect of the MJO on SSW frequency is unknown, and the teleconnection mechanism, its planetary wave propagation path, and time scale are still not completely understood. The Arctic stratosphere response to increased MJO forcing expected in a warmer climate using two models is studied: the comprehensive Whole Atmosphere Community Climate Model and an idealized dry dynamical core with and without MJO-like forcing. It is shown that the frequency of SSW events increases significantly in response to stronger MJO forcing, also affecting the averaged polar cap temperature. Two teleconnection mechanisms are identified: a direct propagation of MJO-forced transient waves to the Arctic stratosphere and a nonlinear enhancement of stationary waves by the MJO-forced transient waves. The MJO-forced waves propagate poleward in the lower stratosphere and upper troposphere and then upward. The cleaner results of the idealized model allow identifying the propagating signal and suggest a horizontal propagation time scale of 10–20 days, followed by additional time for upward propagation within the Arctic stratosphere, although there are significant uncertainties involved. Given that the MJO is predicted to be stronger in a warmer climate, these results suggest that SSW events may become more frequent, with possible implications on tropospheric high-latitude weather. However, the effect of an actual warming scenario on SSW frequency involves additional effects besides a strengthening of the MJO, requiring further investigation.
Co-ingested alcohol and the timing of deliberate self-poisonings
Authors: Chitty Kate M , Kirby Katharine , Osborne Nicholas J , Isbister Geoffrey K , Buckley Nicholas A
Published: August 2017

Objective:

Investigating diurnal variation in the timing of suicidal behaviours offers opportunity to better understand its various proximal risk factors. Acute use of alcohol is a potent proximal risk factor for suicidal behaviour, though the nature of this risk is poorly understood. The aim of this study was to compare the diurnal variation in time of poison ingestion between deliberate self-poisonings that involve alcohol versus those that do not.

Methods:

A retrospective analysis of consecutive presentations to a toxicology service following deliberate self-poisoning, 1996–2016. An independent samples Kolmogorov–Smirnov test was performed to test the null hypothesis that the diurnal distribution of poison ingestion time was equal across self-poisonings that did and did not involve alcohol co-ingestion. Presence of circadian rhythmicity was established using cosinor analysis.

Results:

A total of 11,088 deliberate self-poisoning records, for 7467 patients (60.8% females), were included in the analysis. In all, 31.3% of the total records involved alcohol co-ingestion. Distribution of exposure time was significantly different between deliberate self-poisonings that did and did not involve alcohol ( p < 0.001). The alcohol co-ingestion group showed a significantly greater prominent peak with poisoning occurring later in the evening (~20:00 hours) compared to poisonings that did not involve alcohol (~18:00 hours).

Conclusion:

This study exposed the differential diurnal patterns in deliberate self-poisoning according to the presence of alcohol co-ingestion. This analysis adds to the accumulating evidence that suicidal behaviour that involves alcohol co-ingestion represents a distinct subtype, which may be driven by alcohol consumption patterns in society. This also means that this large proportion of deliberate self-poisonings may not otherwise have occurred if it were not for alcohol consumption, underscoring the importance of drug and alcohol services for alcohol-related self-harm.

Spatial ability has been valued as a talent domain and as an assessment form that reduces cultural, linguistic, and socioeconomic status biases, yet little is known of the spatial ability of students in gifted programs compared with those in general education. Spatial ability is considered an important indicator of potential talent in the domains of science, technology, engineering, and mathematics (STEM). This study explored undergraduate students’ spatial ability, focusing on mental rotation, by investigating the relationships of three variables with performance on a spatial ability test, in terms of test scores and test completion time. A three-way analysis of variance revealed statistically significant main effects of gifted program participation, choice of academic major, and gender, suggesting that students who participated in a gifted program, who majored in a STEM discipline, or who were male outperformed their counterparts on a measure of spatial ability when the other conditions were equivalent. No interaction effects existed among the three variables, indicating that none of them functioned as a moderator of students’ performance on the spatial ability assessment. However, when spatial ability was considered as a mediating variable in a path model, gender had the largest total effect on the probability of students majoring in a STEM area. In addition, the more time students spent on the spatial ability test, the better they tended to perform, which is a finding inconsistent with current literature.
The battle for ‘Middle-earth’: The constitution of interests and identities in The Hobbit dispute
Authors: McLaughlin Colm , Bridgman Todd
Published: August 2017

This article draws on an industrial dispute over the filming of The Hobbit in New Zealand in 2010 to contribute to the theorisation of the interplay between interests and identities and our understanding of mobilisation and collective identity. While industrial disputes are typically viewed as conflict between groups with opposing material interests, this may miss the way in which both the identities of those involved and their interests are discursively constituted in articulatory processes. Specifically, we apply Laclau and Mouffe’s discourse theory and in doing so demonstrate that the dispute was more than a conflict over working conditions, it was a hegemonic struggle to fix meaning. In making this conceptual contribution we highlight a tendency within industrial relations analysis to reify interests.
Successful Goal-Directed Memory Suppression is Associated With Increased Inter-Hemispheric Coordination Between Right and Left Frontoparietal Control Networks
Authors: Smith Ryan , Alkozei Anna , Bao Jennifer , Killgore William D. S.
Published: August 2017

The neural basis of suppressing conscious access to one’s own memories has recently received considerable attention, with several studies suggesting this process engages frontal-parietal cognitive control regions. However, researchers to date have not examined the way right and left hemisphere cognitive control networks coordinate with one another to accomplish this. We had 48 participants (25 female) complete a Think/No Think (T/NT) task for memories of emotionally unpleasant visual scenes while undergoing functional magnetic resonance imaging. We used generalized psychophysiologic interaction analyses to examine functional connectivity between right and left hemisphere frontal-parietal regions during memory suppression. Participants who were better at memory suppression, as assessed by greater numbers of forgotten memories in the NT than T conditions, also showed greater functional connectivity between multiple right and left hemisphere control regions. This suggests that individual differences in memory suppression ability may be partially explained by differences in task-specific inter-hemispheric coordination.
The Structure of Intelligence in Childhood: Age and Socio-Familiar Impact on Cognitive Differentiation
Authors: Martins Ana Azevedo , Gomes Cristiano Mauro Assis , Alves Ana Filipa , Almeida Leandro da Silva
Published: August 2017

The Cattell-Horn-Carroll theory is the principal model at present to define and assess intelligence. However, several authors have suggested that the structure of intelligence is not stable throughout life. For example, children tend to present a general ability, which is invested in the development of specific and differentiated abilities during adolescence, reflecting the effect of schooling, experiences, and interests. In this study, an intelligence nine subtests battery was applied to a sample of 470 5-, 7-, and 9-year-old Portuguese children, from public and private basic schools. Two structure models have been tested, one assuming a global general factor loading by the nine subtests, and a second one formed by two factors integrating the verbal and non-verbal subtests. The results provide evidence of better fit of the second model where intelligence performance is organized in traditional verbal and non-verbal factors. This structure model is confirmed taking 5-, 7-, and 9-year-old children subgroups. A posterior path analysis verifies the impact of socio-familial variables in both factors. More than parents’ educational levels and professional status, the results suggest the sibship size appears as more relevant on explanation of children cognitive performance.
Political education

If this superstitious fear of spirits were taken away, and with it, prognostics from dreams, false prophecies, and many other things depending thereon, by which crafty ambitious persons abuse the simple people, men would be much more fitted than they are for civil obedience. And this ought to be the work of the schools [Thomas HObbes1]
Persistence of immigrants with part-time university education
Authors: Bhatnagar Joti
Published: August 2017

The study was designed to test the hypothesis that immigrants have greater motivation for education than the local population. The sample consisted of 612 part-time undergraduate students at an English-language university in Montreal who completed a specially designed questionnaire. Analysis revealed greater drop-out among students who were born in Canada, and those with English as their home language. Greater persistence was found among students born in developing countries, and those with home language other than English. Immigration status and mother tongue were not related to drop-out persistence. The results of the study support previously published, though not scientifically tested, hunches.
Staff-room conversation and the curriculum
Authors: Rodger I. A.
Published: August 2017

This paper looks at a hitherto neglected area of life of a school, that of the staff room, and considers the possibility that educational discussions within the staff room may affect the ways in which school personnel perceive the aims of education.

Research was carried out in junior schools in an inner urban area, and significant differences in the extent and the kind of educational conservations in staffrooms were revealed. Further investigation showed that these differences may reflect different educational ideologies in operation.
An example from the Banbury Enquiry of a three-dimensional contingency table for the chi-square test
Authors: Selkirk K. E.
Published: August 2017

A recent book by David Newbold (1977) on the Banbury Enquiry into Ability Grouping contains an analysis of children's choice of friends. The variables concerned are sex, mixed ability/streamed classes, and closeness of ability of the friendship pairs as measured by a verbal reasoning test at the end of the first year of secondary schooling. The method of analysis was such that all three variables were dichotomous. This article re-analyses Newbold's data by using a little known development of the chi-square test and suggests that this technique deserves to be more widely known in educational research.
Children from socially disadvantaged families and special education: part II
Authors: Phillips C. J.
Published: August 2017

In the identification of special educational needs, common standards of cognitive and social development, and of school learning, should be applied to all children, including those from severely socially disadvantaged families. The condition of urban poverty does not result in a minority culture for the rearing of children which is different from the prevailing culture, and which would require different standards to be applied to its children. Positive discrimination, like the policy of higher priority in the distribution of resources towards schools in areas of high deprivation, is not an alternative to individual clinical assessment of need and special educational provision.
Initial Caution among Students towards Micro-teaching
Authors: Gibbs I.
Published: August 2017

In contrast to much previous research, which has reported a fairly positive response amongst students to microteaching the present article outlines the results from a study where students disliked certain features of this innovation in teacher education. Possible reasons for this disquiet are considered and the implications for future programmes of microteaching are discussed.
Coping Actions and Occupational Stress among School Teachers
Authors: Kyriacou C.
Published: August 2017

A questionnaire was used to identify the relative frequency with which a sample of comprehensive school teachers used various actions to cope with occupational stress. The most frequently used coping actions reported were ‘try to keep things in perspective’, ‘try to avoid confrontations’ and ‘try to relax after work’. A principal components analysis of the coping actions revealed three factors which were labelled ‘express feelings and seek support’, ‘take considered actions’ and ‘think of other things’.
Some Insights into the Problem of Adult Education Participation in Nigeria
Authors: Urevbu Andrew O.
Published: August 2017

This study investigated the influence of selected positional and psychological factors on evening-class participants in two states in Nigeria: North-Central and North-Western states. * The study also described the motivational bases of their participation. It was regarded as necessary to duplicate this study and know whether or not the characteristics and motivation of participants in the two states are similar. This should be important to researchers since comparisons between two states might lead to valid generalisations. The practical value of this study is that it revealed some characteristics of the people who attend this kind of class. The exploration of the problem of participation at a multivariate level was suggested.
Personality, Reading Ability and Response to Classroom Lessons among a Residential Sample
Authors: O'hagan Frank J.
Published: August 2017

When normal readers and very poor readers in a residential school for delinquent boys were compared on personality measures it was found that the poorer readers were significantly lower on irritability, psychoticism and a global measure of aggression and hostility than the normal readers. They were also higher on a ‘lie’ scale which further analysis appeared to link with positive responses to lessons among the total sample. Teachers reported the lower achievers to have less ability regarding concentration and to be more fearful of new experiences. Poorer interpersonal relationships as measured by self-reported aggression and hostility among the group as a whole were associated with a negative response to classroom activities.
