Authors: Gupta Isha , Oakey Zack , Ahmed Faisal , Ambati Balamurali K.
Published: May 2014

Background: We report 2 patients who have undergone radial keratotomy (RK) preceding ReSTOR® multifocal intraocular lens (IOL; Alcon, Fort Worth, Tex., USA) implantation in their nondominant eyes and TECNIS® monofocal IOL (Abbott Medical Optics, Abbott Park, Ill., USA) in their dominant eyes. Methods: Retrospective review of 2 patients who underwent hybrid monovision with ReSTOR® multifocal and TECHNIS® monofocal IOLs at the time of cataract surgery after a remote history of RK. Results: Implantation of the ReSTOR® multifocal and the TECHNIS® monofocal IOLs was successful, with no reported adverse events. The patients were able to achieve spectacle freedom. Conclusion: We report a novel technique for the management of post-RK patients to optimize their chances for spectacle independence.
Associations between vitamin K status and haemostatic and inflammatory biomarkers in community-dwelling adults

Published: May 2014

Vitamin K is integral to haemostatic function, and in vitro and animal experiments suggest that vitamin K can suppress production of inflammatory cytokines. To test the hypothesis that higher vitamin K status is associated with lower haemostatic activation and inflammation in community-dwelling adults, we analysed the cross-sectional association between serum phylloquinone (vitamin K1) with haemostatic and inflammatory biomarkers in 662 participants in the Multi- Ethnic Study of Atherosclerosis (MESA) [mean (SD) age=62 (10) years; 46% female; 37% Caucasian, 25% African-American, 25% Hispanic, 13% Chinese-American]. Following adjustment for demographic and lifestyle characteristics, medication use, triglycerides and body mass index, those in the highest quartile of serum phylloquinone had significantly lower circulating interleukin-6 [adjusted mean (SEM) pmol/l: quartile 4 (Q4)=1.22 (0.07), quartile 1 (Q1)=1.45 (0.07); p-trend<0.01], C-reactive protein [adjusted mean (SEM) mg/dl: Q4=1.57 (0.11), Q1=2.08 (0.18); p-trend=0.02], soluble intercellular adhesion molecule-1 [adjusted mean (SEM) ng/ml: Q4=247 (11), Q1=288 (11); p-trend=0.02], and plasmin-antiplasmin complex [adjusted mean (SEM) nmol/l: Q4=4.02 (0.1), Q1=4.31 (0.1), p-trend=0.04]. We detected an interaction between age and serum phylloquinone with respect to factor VIII and D-dimer (interaction p-values=0.03 and 0.09, respectively). Among participants ≥70 years, serum phylloquinone was inversely associated with factor VIII activity (p-trend=0.06) and positively associated with D-dimer (p-trend=0.01), but was not associated with either marker among participants <70 years (both p≥0.38). In contrast, dietary phylloquinone intake was not associated with any inflammatory or haemostatic biomarker evaluated (all p-trend>0.11). These findings are consistent with laboratorybased studies that suggest a possible anti-inflammatory role for vitamin K. Whether or not these associations predict clinical outcomes linked to elevated inflammation or haemostatic activation remains to be determined.

Published: May 2014

Tertiary lymphoid organs emerge in tissues in response to nonresolving inflammation. Recent research characterized artery tertiary lymphoid organs in the aorta adventitia of aged apolipoprotein E–deficient mice. The atherosclerosis-associated lymphocyte aggregates are organized into distinct compartments, including separate T-cell areas harboring conventional, monocyte-derived, lymphoid, and plasmacytoid dendritic cells, as well as activated T-cell effectors and memory cells; B-cell follicles containing follicular dendritic cells in activated germinal centers; and peripheral niches of plasma cells. Artery tertiary lymphoid organs show marked neoangiogenesis, aberrant lymphangiogenesis, and extensive induction of high endothelial venules. Moreover, newly formed lymph node–like conduits connect the external lamina with high endothelial venules in T-cell areas and also extend into germinal centers. Mouse artery tertiary lymphoid organs recruit large numbers of naïve T cells and harbor lymphocyte subsets with opposing activities, including CD4
+
and CD8
+
effector and memory T cells, natural and induced CD4
+
regulatory T cells, and memory B cells at different stages of differentiation. These data suggest that artery tertiary lymphoid organs participate in primary immune responses and organize T- and B-cell autoimmune responses in advanced atherosclerosis. In this review, we discuss the novel concept that pro- and antiatherogenic immune responses toward unknown arterial wall–derived autoantigens may be organized by artery tertiary lymphoid organs and that disruption of the balance between pro- and antiatherogenic immune cell subsets may trigger clinically overt atherosclerosis.
The Autonomic Nervous System and Hypertension
Authors: Mancia Giuseppe , Grassi Guido
Published: May 2014

Physiological studies have long documented the key role played by the autonomic nervous system in modulating cardiovascular functions and in controlling blood pressure values, both at rest and in response to environmental stimuli. Experimental and clinical investigations have tested the hypothesis that the origin, progression, and outcome of human hypertension are related to dysfunctional autonomic cardiovascular control and especially to abnormal activation of the sympathetic division. Here, we review the recent literature on the adrenergic and vagal abnormalities that have been reported in essential hypertension, with emphasis on their role as promoters and as amplifiers of the high blood pressure state. We also discuss the possible mechanisms underlying these abnormalities and their importance in the development and progression of the structural and functional cardiovascular damage that characterizes hypertension. Finally, we examine the modifications of sympathetic and vagal cardiovascular influences induced by current nonpharmacological and pharmacological interventions aimed at correcting elevations in blood pressure and restoring the normotensive state.
Introduction to a Dandy, Part II
Authors: Morse Benjamin
Published: May 2014

The second half of my introduction to Qoheleth pastes a ‘readymade’ gambler’s bond by Marcel Duchamp alongside the book’s opening chapter. The French dandy’s mock self-portrait highlights the complexities of the biblical Assembler’s name/title, his mischievous ploys in the game of wisdom, the metaphoric significance of the word hebel, and the spinning sensation rendered in reading the text. Constructing a readymade of Qoheleth as Duchamp, I play roulette with the first chapter, following its disconcerting poetics through to the next and retouching the Catalogue of Times with a comic cadence.
Post-War Trauma and Postmodern Love
Authors: Epstein Heidi
Published: May 2014

What biblical critical insights might re-reading the Song of Songs through its contemporary musical afterlives produce? I propose that certain offbeat musical settings of the Song participate in the discursive composition of specifically postmodern versions of love (e.g. those of Berlant, Belsey, Illouz), and thereby disrupt the transmission of normalizing socio-romantic energies within what Lauren Berlant calls “the intimate public sphere.” In this intertextual case study, Ralph Vaughan Williams’ 1925Flos campi– a work usually praised for its harmonious reconciliation of sensual and spiritual musical moods and idioms – becomes a dystopic allegory of postmodern love. Gestating during WWI as Vaughan Williams served in France and Greece, then composed during a post-war decade of collective disenchantment with the Great War’s socio-political balance sheet,Flos campiconstitutes an ambivalent response to both the composer’s individual as well as a more collective experience of national post-war trauma. With help from Roland Boer’s Lacanian reading of the Song (2000), I locate this ambivalence in the composer’s enigmatic treatment of musical pastoralisms and modal-tonal harmonies as well as his expressive deployment of formal, motivic, and thematic repetition. The dissonant erotic semiotics that these techniques produce inFlos campican be enlisted today to challenge religio-rhetorical co-optations of the Song to bolster heteronormative institutions of love, sexuality, marriage and family by way of the Song’s supposedly timeless message that “Love Conquers All.” Correlatively, readingFlos campias a product of post-war trauma and an allegory of postmodern love invites biblical critics to hear the text’s pastoralisms with fresh “ears.”
The Challenge of Moroccan Cultural Journals of the 1960s
Authors: Parrilla Gonzalo Fernández
Published: May 2014

Abstract

A few years after Morocco’s much longed-for achievement of independence (1956), a new generation of intellectuals too young to have participated in what is widely called the nationalist movement burst onto the cultural and political scenes, and shifted the focus of debate from the “glorious” past towards social and international realities. The 1960s witnessed the appearance of a diverse group of political, scientific and especially cultural and literary journals that changed the course of intellectual life in Morocco. The creation of these new channels of expression out of the emerging institutions of independent Morocco meant a rupture with the prevailing patterns dominated by nationalist and salafī ideals. This article intends to highlight the role and spirit of these generally overlooked journals within their contextual and historical framework.
Middle Persian abāz-handāxtan
Authors: Saadat Yusef
Published: May 2014

Abstract

the verb abāz-handāxtan is used in Dēnkard IV. Different definitions of the verb caused two divergent interpretations of the history of the Zoroastrians scriptures during Sasanian era. This article does not attempt to provide a third category of meaning, but tries to suggest a subtle modification to the traditionally accepted meaning of ‘to collate’. The new nuanced meaning is derived from New Persian texts, which include similar usage of the verb and were written not much later than Middle Persian ones. The suggested meaning is ‘to (re-)measure’.
The March Events and Baku Commune of 1918
Authors: Smith Michael G.
Published: May 2014

This article investigates the March Events of 1918: city-wide fighting for control of Baku that involved the Bolshevik party, the Red Guards, and various Armenian and Azerbaijani militias. Besides many of these combatants, thousands of innocent Azerbaijanis and others (Caucasus peoples and Persians) perished in the hostilities. Focusing on the Events as an exercise of power and violence, I argue that the establishment of the Baku Commune (like the later formation of the multi-national Soviet Union) was indivisible from these circumstances of national and sectarian war. Drawing from Azerbaijani sources long-suppressed by the Communist regime, I recount some of the key contexts, mechanics, and legacies of the Events. As an elucidation of the facts, this study sets out to help historians calibrate their interpretations, better weigh the nature of Soviet power, and refine what we usually term “Armenian” or “Azerbaijani” aggression. These peoples were not preternaturally disposed to violence. Suffering was not the exclusive province of either community. Rather, political strategies have drawn them into cycles of violence and bonds of recrimination that have recurred sporadically into the present day.

Timing performance maintained under the free-operant psychophysical procedure (FOPP) is sensitive to 5-hydroxytryptamine (5-HT)1A and 5-HT2A receptor stimulation. Agonists of these receptors displace the psychometric function towards shorter durations, reducing , the index of central tendency of timing. Here we report the effects of Ro-600175, a selective 5-HT2C receptor agonist, and mCPP, a 5-HT receptor agonist with high affinity for 5-HT2C receptors and lower affinity for 5-HT1A, 5-HT1B and 5-HT2A receptors, on timing behaviour. Rats were trained under the FOPP to press two levers (A and B) in 50-s trials in which reinforcers were provided intermittently for responding on A in the first half, and B in the second half of the trial. Percent responding on B (%B) was recorded in successive 5-s epochs of the trials; logistic psychometric curves were fitted to the data from each rat under each treatment condition for derivation of timing indices [ (time corresponding to %B = 50%), Weber fraction]. The rats received systemic treatment with Ro-600175, mCPP, and mCPP in combination with antagonists of 5-HT1A (WAY-100635), 5-HT1B (isamoltane), 5-HT2A (MDL-100907) or 5-HT2C (SB-242084) receptors. mCPP (2.5 mg kg−1 i.p.), but not Ro-600175 (1, 2, 4 mg kg−1 i.p.), reduced . SB-242084 (0.6 mg kg−1 i.p.) potentiated mCPP’s effect on . mCPP’s effect on was not altered by isamoltane (8.0 mg kg−1 i.p.), but was attenuated by MDL-100907 (1.0 mg kg−1 i.p.) and WAY-100635 (0.1 mg kg−1 s.c.). The results suggest that mCPP’s effect on timing is mediated by an agonistic action at 5-HT1A and 5-HT2A, but not 5-HT1B, receptors. The role of 5-HT2C receptors is unclear, in view of SB-242084’s ability to potentiate the effect of mCPP, while Ro-600175 had no effect on . The possibility is considered that 5-HT2C receptors may counteract 5-HT1A and/or 5-HT2A receptor-mediated effects on timing performance.
Novel Inversions in Auditory Sequences Provide Evidence for Spontaneous Subtraction of Time and Number

Published: May 2014

Animals, including fish, birds, rodents, non-human primates, and pre-verbal infants are able to discriminate the duration and number of events without the use of language. In this paper, we present the results of six experiments exploring the capability of adult rats to count 2–6 sequentially presented white-noise stimuli. The investigation focuses on the animal’s ability to exhibit spontaneous subtraction following the presentation of novel stimulus inversions in the auditory signals being counted. Results suggest that a subtraction operation between two opposite sensory representations may be a general processing strategy used for the comparison of stimulus magnitudes. These findings are discussed within the context of a mode-control model of timing and counting that relies on an analog temporal-integration process for the addition and subtraction of sequential events.

Published: May 2014

The rapid development of science and technology has enabled finer and finer resolutions in atmospheric general circulation models (AGCMs). Parallelization becomes progressively more critical as the resolution of AGCMs increases. This paper presents a new parallel version of the finite-difference Gridpoint Atmospheric Model of the Institute of Atmospheric Physics (IAP)–State Key Laboratory of Numerical Modeling for Atmospheric Sciences and Geophysical Fluid Dynamics (LASG; GAMIL) with various parallel optimization strategies, including two-dimensional hybrid parallel decomposition; hybrid parallel programming; parallel communications for coupling the physical packages, land surface, and dynamical core; and a cascading solution to the tridiagonal equations used in the dynamical core. The new parallel version under two different horizontal resolutions (1° and 0.25°) is evaluated. The new parallel version enables GAMIL to achieve higher parallel efficiency and utilize a greater number of CPU cores. GAMIL1° achieves 37.8% parallel efficiency using 960 CPU cores, while GAMIL0.25° achieves 57.5% parallel efficiency.
ISO-Modulating Effects on the East Asian Summer Monsoon Circulation Patterns Associated with Southern Taiwan’s Monsoon Rainfall
Authors: Ko Ken-Chung , Chiu Po-Sheng
Published: May 2014

In this study, the circulation patterns of the summer monsoon associated with monsoon rainfall in southern Taiwan were analyzed and two types of monsoon patterns were defined. The first type was characterized by a broad low pressure area extending northeastward from a low pressure center near southern China to southern Japan. Strong southwesterly flows were observed over the southern flank of the monsoon trough. The second type of monsoon pattern was characterized by a strong westward-extending anticyclone in the area north of Taiwan (including central China, South Korea, and Japan), and a weaker east–west-elongated monsoon trough south of Taiwan, driving the easterly flow to southern Taiwan. The modulating effect of intraseasonal oscillations (ISOs) on these monsoon flow patterns indicates that as ISOs propagate northwestward toward southern China, they create favorable conditions for developing and strengthening southwesterly flows and convection. However, because of the latitudinal limit of northwestward-propagating ISOs, only the edge of the strongest convection over the southern flank of the ISO cyclonic circulation reaches southern Taiwan during the westerly phase. Thus, although the westerly ISO pattern appears to be stronger than the easterly pattern, it brings less rainfall to southern Taiwan. Through the tightening of pressure gradients, the ISO typically generates anomalous cyclones (anticyclones) that can affect the southwesterly and northeasterly flows near its southern (northern) and northern (southern) rims. Therefore, fluctuations in the low-frequency background flow can exert a notable effect on the monsoon rainfall and associated circulation systems near Taiwan.
Glechoma hederacea Suppresses RANKL-mediated Osteoclastogenesis

Glechoma hederacea (GH), commonly known as ground-ivy or gill-over-the-ground, has been extensively used in folk remedies for relieving symptoms of inflammatory disorders. However, the molecular mechanisms underlying the therapeutic action of GH are poorly understood. Here, we demonstrate that GH constituents inhibit osteoclastogenesis by abrogating receptor activator of nuclear κ-B ligand (RANKL)-induced free cytosolic Ca2+ ([Ca2+]i) oscillations. To evaluate the effect of GH on osteoclastogenesis, we assessed the formation of multi-nucleated cells (MNCs), enzymatic activity of tartrate-resistant acidic phosphatase (TRAP), expression of nuclear factor of activated T-cells cytoplasmic 1 (NFATc1), and [Ca2+]i alterations in response to treatment with GH ethanol extract (GHE) in primarily cultured bone marrow–derived macrophages (BMMs). Treatment of RANKL-stimulated or non-stimulated BMMs with GHE markedly suppressed MNC formation, TRAP activity, and NFATc1 expression in a dose-dependent manner. Additionally, GHE treatment induced a large transient elevation in [Ca2+]i while suppressing RANKL-induced [Ca2+]i oscillations, which are essential for NFATc1 activation. GHE-evoked increase in [Ca2+]i was dependent on extracellular Ca2+ and was inhibited by 1,4-dihydropyridine (DHP), inhibitor of voltage-gated Ca2+ channels (VGCCs), but was independent of store-operated Ca2+ channels. Notably, after transient [Ca2+] elevation, treatment with GHE desensitized the VGCCs, resulting in an abrogation of RANKL-induced [Ca2+]i oscillations and MNC formation. These findings demonstrate that treatment of BMMs with GHE suppresses RANKL-mediated osteoclastogenesis by activating and then desensitizing DHP-sensitive VGCCs, suggesting potential applications of GH in the treatment of bone disorders, such as periodontitis, osteoporosis, and rheumatoid arthritis.
Decoupling internal model control for non-square processes based on equivalent transfer function
Authors: Jin Qibing , Jiang Beiyan , Wang Qi , Shan Guanfei
Published: May 2014

A novel design method of decoupling internal model control is proposed for non-square processes with multiple time delays that are often encountered in complicated industrial processes. The method can obtain a realizable decoupling controller of non-square processes with more inputs than outputs by inserting some compensated terms, which are derived analytically. Meanwhile, based on the relative normalized gain array, an equivalent transfer function matrix is introduced to approximate the pseudo-inverse of the process transfer function matrix, which makes the design of decoupling internal model control simple and easy to calculate. Filters are added to the control structure to improve the robustness. Simulation results have proved the effectiveness and reliability of the proposed method.
Knowledge Appropriation and Identity: Toward a Multi-Discourse Analysis
Authors: Kamoche Ken , Beise-Zee Rian , Mamman Aminu
Published: May 2014

Knowledge appropriation has been underpinned by an assumption of the organization’s ‘entitlement’ to appropriate knowledge and the outcomes of its utilization. Given the complexity of knowledge and the potentially conflicting views held about it, this assumption is revealed to be theoretically imprecise in the way it marginalizes alternative voices through the pursuit of competitive advantage and ‘value capture’. We attribute this approach to the functionalist analytical lens which sees knowledge as an asset appropriable almost exclusively by the organization in the form of financial/economic ‘rents’. In order to advance understanding of the multi-faceted nature of the organization-individual appropriation regime, we make the case for an expansion of the discursive space for talking about the phenomenon, and posit the concept of ‘property in knowledge’ which we tie to the way individuals construct their identities.
A study of the inter-rater reliability of a test battery for use in patients after total hip replacement
Authors: Mikkelsen Lone Ramer , Mikkelsen Søren , Søballe Kjeld , Mechlenburg Inger , Petersen Annemette Krintel
Published: May 2014

Objective:

To assess the within-day inter-rater reliability of a test battery of functional performance, muscle strength and leg extension power on total hip replacement patients.

Design:

A test–retest design was used.

Setting:

Orthopaedic department at a Regional Hospital in Denmark.

Subjects:

Two convenience samples of 20 total hip replacement patients were included.

Intervention:

The tests were performed three months after total hip replacement. Two raters performed test and re-test, with two hours rest in-between.

Main measures:

The test battery included: sit-to-stand performance, 20-metre maximum walking speed, stair climb performance, isometric muscle strength (hip abduction/flexion), and leg extension power. Absolute reliability was assessed with Bland Altman plots, standard error of measurement (SEM), and minimal detectable change. Relative reliability was assessed with intra-class correlation coefficient.

Results:

Systematic differences between testers were seen in tests of walking speed (0.32 seconds p = 0.03) and stair climb performance (0.18 seconds p = 0.003). In per cent of the grand mean, the standard error of measurement was 3%–10%, indicating the measurement error on a group level, and the minimal detectable change was 10%–27%, indicating the measurement error on an individual level. The intra-class correlation coefficients were above 0.80 in all tests (range 0.83–0.95).

Conclusions:

The tests showed acceptable relative and absolute inter-rater reliability on a group level, but not on an individual level (except from test of walking speed and stair climb performance). Systematic differences between testers were considered clinically irrelevant (0.3 and 0.2 seconds).
Combining physical training with transcranial direct current stimulation to improve gait in Parkinson’s disease: a pilot randomized controlled study
Authors: Kaski D , Dominguez RO , Allum JH , Islam AF , Bronstein AM
Published: May 2014

Objective:

To improve gait and balance in patients with Parkinson’s disease by combining anodal transcranial direct current stimulation with physical training.

Design:

In a double-blind design, one group (physical training; n = 8) underwent gait and balance training during transcranial direct current stimulation (tDCS; real/sham). Real stimulation consisted of 15 minutes of 2 mA transcranial direct current stimulation over primary motor and premotor cortex. For sham, the current was switched off after 30 seconds. Patients received the opposite stimulation (sham/real) with physical training one week later; the second group (No physical training; n = 8) received stimulation (real/sham) but no training, and also repeated a sequential transcranial direct current stimulation session one week later (sham/real).

Setting:

Hospital Srio Libanes, Buenos Aires, Argentina.

Subjects:

Sixteen community-dwelling patients with Parkinson’s disease.

Interventions:

Transcranial direct current stimulation with and without concomitant physical training.

Main measures:

Gait velocity (primary gait outcome), stride length, timed 6-minute walk test, Timed Up and Go Test (secondary outcomes), and performance on the pull test (primary balance outcome).

Results:

Transcranial direct current stimulation with physical training increased gait velocity (mean = 29.5%, SD = 13; p < 0.01) and improved balance (pull test: mean = 50.9%, SD = 37; p = 0.01) compared with transcranial direct current stimulation alone. There was no isolated benefit of transcranial direct current stimulation alone. Although physical training improved gait velocity (mean = 15.5%, SD = 12.3; p = 0.03), these effects were comparatively less than with combined tDCS + physical therapy ( p < 0.025). Greater stimulation-related improvements were seen in patients with more advanced disease.

Conclusions:

Anodal transcranial direct current stimulation during physical training improves gait and balance in patients with Parkinson’s disease. Power calculations revealed that 14 patients per treatment arm (α = 0.05; power = 0.8) are required for a definitive trial.
SoftCubes: Stretchable and self-assembling three-dimensional soft modular matter
Authors: Yim Sehyuk , Sitti Metin
Published: May 2014

This paper proposes a self-assembling soft modular matter, called SoftCubes, where soft-bodied modules are disassembled into a flexible string by an external tension and self-assemble into the preprogrammed three-dimensional (3D) shape. The developed soft modular matter has three main design features. Firstly, entire modules of the 3D shape are serially connected. Such a structure allows all the modules to be disassembled by external tension. Secondly, the outer body of the modules and the connecting parts are made of soft stretchable elastomer. Due to the soft body of the modules, after disassembling, the serially connected modules become a highly flexible and soft string, and have an extreme shape adaptation capability. Also, if the external tension is removed, the preprogrammed 3D shape is recovered by the elastic restoring force of soft-bodied modules. Finally, embedded small permanent magnets induce magnetic self-assembling forces and maintain a mechanical robustness of the 3D shape of module assembly. Due to the magnetic self-assembly, the soft modules are precisely aligned with neighboring modules in a lattice structure. The paper also presents an algorithm to generate the serial connection path of modules for creating a given 3D shape. Various physical interactions between self-assembling module prototypes are visualized in two-dimensional motion tracking experiments. Finally, the shape reconfiguration ability of soft modular matter is demonstrated. SoftCubes is a new class of programmable modular matter where shape memory ability is embedded in the structure, and shows a physical implementation of various 3D shapes with a high resolution and a high scalability.
Biogenic volatile organic compounds emissions at high temperatures of common plants from Mediterranean regions affected by forest fires
Authors: Courty Léo , Chetehouna Khaled , Lemée Laurent , Fernandez-Pello Carlos , Garo Jean-Pierre
Published: May 2014

Vegetal species emit biogenic volatile organic compounds at elevated temperatures. Because of their combustibility, biogenic volatile organic compounds can modify the wildland fires propagation dynamics, changing them from a moderate behavior to an explosive propagation. This phenomenon is known as an accelerating forest fire. The origin of such phenomena can be the accumulation of biogenic volatile organic compounds in concentrations close to their lower flammability limit in seasons where the plants are themselves very flammable. There is a lack of information on the biogenic volatile organic compounds emissions of vegetal species typically found in wildland fires at temperatures higher than ambient temperature. In this work, we used a flash pyrolysis device linked to a gas chromatograph/mass spectrometer to investigate experimentally the biogenic volatile organic compounds emissions of Thymus vulgaris, Lavandula stœchas, and Cistus albidus between 70°C and 180°C. High amounts of terpenoid compounds were found, except for C. albidus emissions, including thymol, l-fenchone, and 3-hexen-1-ol. The information provided in this work could help to improve the characterization of thermal degradation of vegetal fuels and to incorporate the biogenic volatile organic compounds combustion in physical forest fires models. They also show that under the right circumstances, biogenic volatile organic compounds from these vegetal species could contribute to the development of an accelerating forest fire.
Heterogeneity of Relationally Aggressive Adolescents in Taiwan
Authors: Cheng Ching-Ling
Published: May 2014

Relational aggressors mistreat their targets in covert ways; however, they also inflict psychological harm to victims. A clarification of the distinctive function of the perpetrators’ destructive patterns would be helpful for interventional consideration. This study’s purpose was to, first, explore the classification of relational aggression (RA) by means of operational channels, and then, to examine the psychosocial characteristics of each subtype. The participants were 860 junior high school students (431 boys, Mage = 14.2) from four schools in Taiwan. Self-reported measures of empathy, normative beliefs of RA, and coping strategy of interpersonal conflicts were used for data collection, as well as peer-nominated measures of RA and peer acceptance. By means of cluster analyses, five clusters were identified: direct, indirect, severe/combined, mild/combined, and uninvolved. The meaningfulness of the resultant cluster solution was examined through the analysis of social-cognitive, affective, and behavioral features as well as psychosocial adjustment. The findings indicated that different subgroups of relational aggressors demonstrated distinct psychosocial characteristics. In particular, in contrast to non-involved adolescents, the direct group tended to regard RA as acceptable, and the indirect group was more likely to rely on social support and have negative emotional reactions in dealing with interpersonal problems.

Dating violence is a complex phenomenon, and researchers continue to examine a wide range of precursors and contributing factors. Evidence indicates that violent intimate partners may be more likely to have personality disorders and dependency and attachment problems compared with non-violent ones. The aim of the present study is to evaluate the interaction between the personality profiles, pattern of psychopathology, and dating violence among university students in Obafemi Awolowo University, Ile-Ife. The study utilized a cross-sectional survey design with a total of 400 students selected using a multistage sampling technique. They completed the Sociodemographic Data Schedule, the Conflict Tactic Scale (CTS), Eysenck Personality Questionnaire (EPQ), and the General Health Questionnaire (GHQ). Univariate analysis was used to determine the prevalence of dating violence, psychopathology, and personality traits, and these were expressed in percentages. Association at bivariate level was assessed using chi-square and at multivariate level using logistic regression and correlations as was appropriate depending on the type of variable. The age of the respondents ranged between 18 and 35 years ( M = 21.44, SD = 2.99). The prevalence of dating violence in the previous 12 months was 34%, and the prevalence of psychopathology was 15%. In the logistic regression model constructed, it was found that the significant predictors of dating violence were the psychoticism and neuroticism personality traits, which were also found to be positive correlates of psychopathology. The magnitude of dating violence found in this study is comparable with those found in other countries of the world. This study found an association between dating violence and personality in the study population and also between certain personality traits and psychopathology. The personality profiles of students could affect their interpersonal relationships greatly, and this fact must feature in dating violence prevention programs.
Does Self-Efficacy Affect Responsiveness to Cognitive Speed of Processing Training?
Authors: Sharpe Chantelle , Holup Amanda A. , Hansen Kevin E. , Edwards Jerri D.
Published: May 2014

Objective: Older adults with higher self-efficacy may be more likely to benefit from some cognitive training approaches. We examined whether self-efficacy serves as a mediator or moderator of responsiveness to cognitive speed of processing training (SOPT). Method: We used data from the Staying Keen in Later Life (SKILL) study ( N = 128) and the Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE) study ( N = 1,400). Both studies assessed cognitive speed of processing (Useful Field of View Test—UFOV) and self-efficacy among community-dwelling older adults who were either randomized to SOPT or control conditions. We constructed regression models examining self-efficacy as a predictor of training responsiveness. Results: Analyses from both studies indicated that participants’ self-efficacy scores were not predictive of training gains from SOPT, as measured by UFOV performance. Discussion: Self-efficacy does not affect older adults’ ability to benefit from cognitive SOPT.
Centrism and the mandarin class: Understanding the meta-politics of Whitehall bureaucratic neutrality

The role of permanent secretary represents the apogee of a career in the Whitehall bureaucracy. Even so it is under-researched and, with exceptions, notably Dunleavy et al. on bureau shaping, under-theorised. Emanating from a longitudinal survey of eight successive permanent secretaries at the Ministry of Education from 1976 to 2011, this paper identifies them as members of a meta-political class who, whilst influencing the policy decisions of politicians, are nonetheless not members of the political class. A model locating them across a spectrum of six related yet distinct genres of ‘centrism’, and a continuum of five contingent descriptive styles is used to illustrate and interpret their praxis.
An 11-stage axial compressor performance simulation considering the change of tip clearance in different operating conditions
Authors: Dong Yang , Xinqian Zheng , Qiushi Li
Published: May 2014

The multistage axial compressor is one of the critical components of aero-engines and plays a key role in their performance, reliability, and economy. Tip clearance has a significant impact on the performance and stability of multistage axial compressors. Due to blade and disk deformations, tip clearance will vary significantly in different operating conditions. Thus, tip clearance should be accurately estimated when evaluating compressor performance. This paper proposes a new model to predict changes of tip clearance of multistage axial compressors in different operating conditions. A first-principles approach is used to estimate the change of tip clearance caused by thermal and mechanical deformation. The span-wise temperature distribution across each stage of the multistage compressors is considered by the proposed model in this paper. The model was validated by General Electric Company (GE) E3 engine experimental results. Using the model, the performance of an 11-stage axial compressor is simulated. The results show that accounting for tip clearance variations has a 0.5% impact on the calculated mass flow rate and a 1% impact on the calculated efficiency. Thus, variations of tip clearance at different operating conditions cannot be ignored and the proposed new model is useful to accurately predict the performance of multistage axial compressor.

Lung cancer incidence over 2005–2010 for 326 Local Authority Districts in England is investigated by ecological regression. Motivated from mis-specification of a Negative Binomial additive model, a semiparametric Negative Binomial M-quantile regression model is introduced. The additive part relates to those univariate or bivariate smoothing components, which are included in the model to capture nonlinearities in the predictor or to account for spatial dependence. All such components are estimated using penalized splines. The results show the capability of the semiparametric Negative Binomial M-quantile regression model to handle data with a strong spatial structure.

Three adult central bearded dragons ( Pogona vitticeps) originating from a commercial breeding facility presented with clinical signs, including anorexia, dehydration, white multifocal lesions on the dorsal aspect of the tongue, blepharospasm, and weight loss. In 1 of 3 lizards, a marked regenerative anemia was noted, and all 3 bearded dragons had erythrocytic intracytoplasmic inclusion bodies. Nine bearded dragons housed in contact also had identical, but fewer intraerythrocytic inclusions. Inclusion bodies examined by electron microscopy had particles consistent with iridoviruses. Attempts to culture the virus were unsuccessful; however, amplification and sequencing of regions of the viral DNA polymerase by polymerase chain reaction confirmed the presence of an iridovirus. One of the bearded dragons died, while the 2 others showing clinical signs were euthanized. The remaining 9 infected bearded dragons of the teaching colony were also euthanized. Postmortem examination revealed a moderate, multifocal, lymphoplasmacytic or mononuclear adenitis of the tongue in the 3 bearded dragons, and a lymphohistiocytic hepatitis with bacterial granulomas in 2 lizards.

Authors: Strickland C. June , Hillaire Elaine
Published: May 2014

Breast and cervical cancers continue to contribute to high cancer mortality rates in American Indian/Alaska Native women; culturally appropriate interventions are needed to influence screening behaviors and to reduce delays in obtaining care. In a pilot feasibility study designed to influence Pacific Northwest American Indian/Alaska Native women’s health screening knowledge and behaviors (breast and cervical), we employed a community-based participatory research approach. Data from interviews with study participants, those involved in implementation of the study and observations were included in the analysis. Study questions focused on training of staff, recruitment of participants, and implementation of the protocol and data management. The complexities of translational, transcultural research and the importance of reporting pilot feasibility studies to the advancement of transcultural research are highlighted in the findings of this research effort.
Perception of HIV Prevention Programs Among Ayoreo Sex Workers in Bolivia

Published: May 2014

The Ayoreo population constitutes one of Bolivia’s most vulnerable ethnic groups in terms of HIV/AIDS. Being a woman, indigenous, and a sex worker signifies belonging to a high-risk group. The aim of this study is to explore the Ayoreo sex workers’ and health agents’ perceptions of HIV/AIDS prevention programs in order to identify variables that could influence their success or failure. This study used an ethnographic methodology that included participant observation and semistructured interviews. In the data collection, participant observation and semistructured interviews with sex workers and key informants were conducted. Three themes emerged from the inductive data analysis: health prevention efforts, cultural inadequacy of prevention programs, and the eventuality of interventions. We conclude that nursing can develop culturally-adequate HIV/AIDS prevention interventions and programs as well as promote health within these populations.
Humanitarian Nursing in Developing Countries
Authors: Lal Shane , Spence Deb
Published: May 2014

Background: Surgical nursing within humanitarian contexts is complex, sporadically described in literature and little understood. Aim: To achieve a deeper understanding of the lived experience of New Zealand nurses providing humanitarian aid within surgical settings and war zones in developing countries. Method: In-depth conversational interviews were undertaken with four New Zealand nurses whose humanitarian experience lay in general surgical, military, and intensive care settings. A qualitative descriptive method as described by Sandelowski, informed by van Manen’s phenomenology in terms of analysis, was used. Results: Specialized knowledge and nursing expertise are recognized to be essential but not sufficient for humanitarian work. Understanding local cultures contributes to positive feelings about work effectiveness. Themes included feeling anxious and misunderstood, practicing differently, and adjusting to life back home. Discussion: This study highlights the need to better prepare nurses who volunteer for humanitarian work, with implications for recruiting organizations, educators, and clinicians.
Effectiveness and Complications Associated With Recombinant Human Bone Morphogenetic Protein-2 Augmentation of Foot and Ankle Fusions and Fracture Nonunions
Authors: Rearick Timothy , Charlton Timothy P. , Thordarson David
Published: May 2014

Background:

Recombinant human bone morphogenetic protein-2 (rhBMP-2) has been used to augment bone healing and fusion in a variety of orthopaedic conditions. However, there is a paucity of data evaluating the potential benefits of its use in foot and ankle surgery. The purpose of this study was to investigate the effectiveness and associated complications with the use of rhBMP-2 in high-risk foot and ankle fusions and fracture nonunions.

Methods:

A total of 51 cases in 48 patients undergoing foot and ankle fusions or fracture nonunion revisions and considered at high risk for subsequent nonunion were identified through a retrospective review in which rhBMP-2 was used as an augment for bone healing. Rate of union, time to union, and associated complications were evaluated.

Results:

Forty-seven of 51 high-risk cases treated with rhBMP-2 united for a per-case union rate of 92.2%. Seventy-eight of 82 individual sites treated with rhBMP-2 united for a per-site union rate of 95.1%. Of the successful unions, the mean time to union was 111 days (95% confidence interval, 101-121). There were no statistically significant differences in time to union with regard to supplementation with bone allograft or autograft or size of rhBMP-2 kit used. Complication rates were low.

Conclusion:

rhBMP-2 was a safe and apparently effective adjunct to bony union in high-risk foot and ankle surgeries. Further randomized controlled trials are warranted.

Level of Evidence:

Level IV, retrospective case series.
The closing of the American mind: ‘American School’ International Relations and the state of grand theory
Authors: Levine Daniel J. , Barder Alexander D.
Published: May 2014

Senior ‘American School’ International Relations theorists — John Mearsheimer and Stephen Walt, Robert Keohane, and others — have evinced a growing concern about a rise of technocratic hypothesis-testing, and a parallel decline in grand theory. We share many of their concerns; yet, we also find such discussions deeply unsatisfying. Grand theory descends into ‘technocracy’ because of reifying and depoliticizing processes deeply woven into both thought and the academic vocation. While confronting such processes is possible, these same scholars are among those who dismiss — and have long dismissed — the key intellectual moves that would sustain such a confrontation. That infelicitous combination, we argue, is unlikely to produce a renaissance of grand theory; indeed, past precedent suggests that it will further stifle it. To suggest how these theorists might better revalorize grand theory, we develop disciplinary-historical case studies around two key research programs: neo-functionalism and structural liberalism. Both were the product of an abiding commitment to grand theory; yet, both fell into reified and depoliticized stances that left little space for such theory. Breaking that cycle of reification and depoliticization might yet be possible; but it will require thinking beyond the call for ‘more grand theory.’

Conditions for nurses’ daily patient education work are unclear and require clarification. The aim was to develop and validate the Nurses’ Patient Education Questionnaire, a questionnaire that assesses nurses’ perceptions of appropriate conditions for patient education work: what nurses say they actually do and what they think about what they do. The questionnaire was developed from a literature review, resulting in the development of five domains. This was followed by ‘cognitive interviewing’ with 14 nurses and dialogue with 5 pedagogical experts. The five domains were identified as significant for assessing nurses’ beliefs and knowledge; education environment; health care organisation; interdisciplinary cooperation and collegial teamwork; and patient education activities. A content validity index was used for agreement of relevance and consensus of items by nurses ( n = 10). The total number of items in the final questionnaire is 60, consisting of demographic items, what nurses report they do and perceptions about patient education in daily work. The questionnaire can be used by managers and nurses to identify possibilities and barriers to patient education in different care contexts.
