Sleep pathology characterization in sickle cell disease: Case–control study
Authors: Mascarenhas Maria Inês , Loureiro Helena Cristina , Ferreira Teresa , Dias Alexandra 
Published: July 2014

SummaryBackgroundChildren and adolescents with sickle cell disease (SCD) have a higher incidence of sleep pathology and obstructive sleep apnea syndrome (OSAS). The nocturnal hypoxemia is a risk to vaso‐occlusive crisis among other SCD morbidities. Our aim was to compare polysomnography (PSG) results in a sample of children with SCD with a sample of children with suspected OSAS without SCD.Design and MethodsA retrospective study compared clinical and PSG parameters. A descriptive analysis and t‐test were done considering P < 0.05 as significant.ResultsPSG was done in 65 children with SCD and 65 control‐children. Control sample was selected to be equal to SCD sample considering gender (53.8% were male), age (mean age was 9.4 years (SD ± 4.6) and AHI (mean 3.57 events/hr).Mean efficiency, latency and percentage of sleep phases in both groups showed no statistically significant differences. Mean SpO2 and minimum SpO2 were lower in SCD group and it was statistically significant (P < 0.01). Enuresis was more frequent in the SCD children group (35.4% vs. 6.2%, P < 0.01).ConclusionComparing children with and without SCD, sleep architecture was similar in both groups and minimum SpO2 was significantly lower in SCD children although both groups had a similar AHI. This is an important issue in these children, so it is essential to have a sleep evaluation in order to prevent complications and co‐morbidities.

An Interdisciplinary Approach to Understanding Readiness for University Partnerships
Authors: Hancock Lua 
Published: July 2014

AbstractModern American higher education has blurred lines and roles of academic affairs, student affairs, and enrollment professionals. In a climate that pushes us to be assessment‐driven, collaborative, outcomes‐orientated, and student‐centered, it is key that we have tools to clearly analyze our own campus culture and structures. Many of the areas that we teach in the higher education setting, such as cross‐cultural theory and business process, can prove helpful when applied to our own campuses. These theoretical frames can assist higher education practitioners to make genuine assessments as to campus readiness for change and create solid plans for how to achieve next goals.
Syntheses and Characterization of Cyanide‐Bridged Bimetallic Compounds Zn(terpy)(H2O)M(CN)4 (terpy = 2,2′:6′,2′′‐ter­pyridine; M = Ni, Pd, Pt) with Linear Chains

Published: July 2014

AbstractThe self‐assembly reaction of zinc ions with tetracyanometalates in the presence of the tridentate chelated ligand 2,2′:6′,2′′‐terpyridine (terpy) yielded three cyanide‐bridged bimetallic compounds of general formula Zn(terpy)(H2O)M(CN)4 [M = Ni (1), Pd (2), Pt (3)]. Compounds 1–3 were characterized by X‐ray diffraction (XRD), infrared spectroscopy (IR), and thermogravimetric (TG) analysis. Single‐crystal XRD analysis revealed that compounds 1–3 are isostructural and the structure consists of [Zn(terpy)(H2O)]2+ moieties and [M(CN)4]2– units linked alternatively to generate a one‐dimensional (1D) linear chain. The chains are further connected together through hydrogen bonding and π–π stacking interactions, forming a 3D supramolecular network. IR spectroscopic analysis indicated the presence of cyanide groups and terpy ligands in the structure. TG and powder XRD results showed that compounds 1–3 have higher thermal stabilities and exhibited irreversible for desorption/resorption of one coordinated water molecule.
A Substituent Change Exerts a Large Dimensionality and Water Tetramer Morphology Difference in Luminescent Cadmium Succinate Coordination Polymers Containing 3‐Pyridylnicotinamide
Authors: Spies Henry J. , LaDuca Robert L. 
Published: July 2014

AbstractHydrothermal reaction of cadmium nitrate and the conformationally flexible dipyridine 3‐pyridylnicotinamide (3‐pna) with a substituted succinic acid derivative afforded a pair of crystalline coordination polymers, whose dimensionality depends critically on the number of 2‐position methyl groups on the acid precursor. The two new crystalline extended metal‐organic solids were structurally characterized by single‐crystal X‐ray diffraction. {[Cd(msuc)(3‐pna)]·2H2O}n (1) (msuc = 2‐methylsuccinate) manifests [Cd(msuc)]n layer motifs that contain {Cd2(OCO)2} dimeric units, linked into a non‐interpenetrated 3D 6‐connected pcu network by tethering anti‐conformation 3‐pna ligands. {[Cd2(dmsuc)2(3‐pna)2]·1.5H2O}n (2) (dmsuc = 2,2‐dimethylsuccinate) shows 1D [Cd(dmsuc)]n ribbons containing {Cd2O2} dimeric units. In turn these are connected into 2D [Cd2(dmsuc)2(3‐pna)2]n layer motifs via anti‐conformation 3‐pna linkers; the layers are decorated by pendant monodentate 3‐pna ligands. The subtle steric variance alters the supramolecular environment for co‐crystallized water molecule tetramers, with a discrete chain seen in 1 and a cyclic ring in 2. Thermal and luminescent properties of these two new materials are also presented.
Amniopatch: Way Forward for Mid-trimester Premature Rupture of Membranes (PROM)
Authors: Gupta Ashutosh , Aneja Anjila , Arora Rupam , Sheghal Renu , Gupta Pooja 
Published: July 2014

AbstractFetal membranes are essential for the maintenance of sterile intrauterine milieu for proper fetal growth and development. Chronic infection and inflammation may lead to progressive stretching, hardening of the membranes, making them less elastic and more susceptible to premature rupture of membranes (PROM). PROM is associated with fetal morbidity and mortality which is inversely proportional to the period of gestation. Amniopatch even though still in experimental stages to be an established treatment for PROM, is a formidable treatment modality which has shown to seal the chorioamniotic leak and prolonging the pregnancy with improved fetal outcome. With increasing intrauterine fetal interventions both diagnostic (amniocentesis) and therapeutic (fetoscopy), amniopatch is an option for persistent amniotic fluid leakage which has shown to effectively seal the chorioamniotic leak in about two-third of the cases.
International note: Prevailing with extracurricular activities in an alcohol‐dominated environment: Sex differences in resilience among middle school youth
Authors: Habib Elana L. , Zimmerman Marc A. , Ostaszewski Krzysztof 
Published: July 2014

ABSTRACTExtracurricular involvement creates an outlet for adolescents to gain skills and resources that assist them in overcoming certain risks. Resiliency theory is applied to study the promotive effects of extracurricular activity involvement as this may help Polish youth overcome risks for alcohol use. Our data include 2903, 13 and 14 year old Polish adolescents. We use regression analysis to test the main and interaction effects of extracurricular involvement after adjusting for demographics and social influences. Sex differences are examined within the resilience framework. We found protective effects of extracurricular involvement for males, but only a compensatory effect for females. Implications for future research and intervention are discussed.
Unexpected Support for European Integration: Memory, Rupture, and Totalitarianism in Arendt's Political Theory
Authors: Verovšek Peter J. 
Published: July 2014

AbstractCollective memory is an important source of social stability, allowing human beings and political communities to integrate new experiences into existing narrative frameworks. In addition to sustaining individual and group identities, remembrance can also maintain cycles of hatred. Building on Arendt's political theory, I present an alternative interpretation of memory as a resource for political change following historical ruptures. This constructive reading focuses on the ability of communities to create new futures out of the shattered pieces of the past. For Arendt, the experience of totalitarianism was a caesura that made nationalist histories, and the nation-state that came with these interpretations of the past, untenable. Following such breaks, communities must reconstruct the past into new narratives. Arendt's unexpected early support for European integration—despite its supranational, technocratic, and economistic qualities—is an example of how memory can function as a resource for political transformation in the aftermath of historical ruptures.
Tocqueville and Nietzsche on the Problem of Human Greatness in Democracy
Authors: Franco Paul 
Published: July 2014

AbstractNietzsche and Tocqueville share a common concern with the tendency to mediocrity and loss of human greatness in democratic life. This essay explores the many similarities in their diagnoses of this problem, which they both view from the distinctive standpoint of aristocracy. Both thinkers focus on the way in which the individualism, preoccupation with material comfort, restlessness, and valorization of compassion that belong to democracy undermine human aspiration, intellectual excellence, and spiritual depth. Nevertheless, they differ sharply in their responses to the problem of human greatness in democracy. Tocqueville calls chiefly upon religion to elevate democratic citizens but otherwise resigns himself to the mediocrity that comes with democratic life. Nietzsche starts from the pessimistic premise that God is dead but more optimistically affirms the possibility of reestablishing aristocracy and finding a new greatness for human beings. The essay ultimately finds Nietzsche's solution more convincing but not without difficulties.

AbstractThe aim of this study was to explore the association between pathological gambling (PG) and anger by assessing whether psychopathology and personality are related to PG and to evaluate gender differences. The sample comprised 71 PGs and 37 healthy controls. Anger, psychopathology and personality were assessed with the STAXI-2, SCL-90-R and TCI-R respectively. Gender did not affect anger expression after stratifying by diagnostic condition (p > .05). Among PG patients, anger, psychopathology and personality measures were correlated with good effect-size (r > .30). Scores in the Anger Temperament (B = 0.21, p = .038) and Anger External-Expression (B = 0.27, p = .029) scales were positively associated with PG severity scores. Anger expression in PG should be considered in future treatment programs.
Characterizing Occupational Risk Perception: the Case of Biological, Ergonomic and Organizational Hazards in Spanish Healthcare Workers
Authors: Portell Mariona , Gil Rosa M. , Losilla Josep M. , Vives Jaume 
Published: July 2014

AbstractUnderstanding how risk is perceived by workers is necessary for effective risk communication and risk management. This study adapts key elements of the psychometric perspective to characterize occupational risk perception at a worker level. A total of 313 Spanish healthcare workers evaluated relevant hazards in their workplaces related to biological, ergonomic and organizational factors. A questionnaire elicited workers' ratings of 3 occupational hazards on 9 risk attributes along with perceived risk. Factor and regression analyses reveal regularities in how different risks are perceived, while, at the same time, the procedure helps to summarize specificities in the perception of each hazard. The main regularity is the weight of feeling of dread/severity in order to characterize the risk perceived (β ranges from .22 to .41;p< .001). Data also suggest an underestimation of expert knowledge in relation to the personal knowledge of risk. Thus, participants consider their knowledge of the risk related to biological, ergonomic, and organizational hazards to be higher than the knowledge attributed to the occupational experts (mean differences 95% CIs [.10, .30], [.54, .94], and [0.52, 1.05]). We demonstrate the application of a feasible and systematic procedure to capture how workers perceive hazards in their immediate work environment.
Photonic crystal fibre‐based polarimetric sensor for cure monitoring of magnetorheological smart composite material

Published: July 2014

A buffer stripped high birefringent photonic crystal fibre based polarimetric sensor is developed for monitoring the curing process of magnetorheological elastomer (MRE) smart composite material. Using the developed sensor, different phases of the MRE curing process are clearly visible from the phase shift variation of the embedded polarisation maintaining photonic crystal fibre (PM‐PCF) sensor. During the curing process, the buffer stripped PM‐PCF exhibits a stress/strain induced phase shift variation from 0 to 1.98 rad. This is a significantly large phase change, which can be used to very clearly identify the different stages in the curing process. For comparison, a fibre Bragg grating sensor is also used for monitoring the internal strain during the curing process and its response does not allow one to reliably distinguish all the curing stages. The present investigation offers a simple non‐destructive method to monitor the curing process of MRE smart composite material.

Published: July 2014

Three‐element in‐phase coherently coupled arrays of vertical cavity surface‐emitting lasers (VCSELs) were fabricated using proton implantation. The arrays show excellent beam quality with a far‐field divergence of 4°, while maintaining a stable in‐phase mode until a maximum output power of 4 mW under continuous‐wave condition. The process for the arrays is simple and the cost is low.

Published: July 2014

The low lithium adsorption capacity of different ion sieves was found to be an important limiting parameter for their use in industrial extraction. The maximum exchange capacity of 6.6 mmol/g obtained till now is not high enough for their economical industrial application. Therefore, an increase in lithium adsorption capacity by studying the effects of three parameters, involving manganese salt compound, lithium salt compound and Li/Mn mole ratio on synthesised ion sieves was investigated. Moreover, the ion sieves capability on the lithium uptake from lithium‐enriched solution was examined by the Taguchi experimental design method by L9 orthogonal array. Continuously, optimum conditions were predicted and confirmed by the experimental results. Based on the results, all mentioned parameters have significant effect on lithium uptake capacity, but lithium salt compound is the most effective factor. Finally, an appropriate ion sieve with lithium adsorption capacity >8.5 mmol/g was synthesised by applying the optimised conditions.
Structured diaphragm with a centre boss and four peninsulas for high sensitivity and high linearity pressure sensors
Authors: Huang Xian , Zhang Dacheng 
Published: July 2014

Using the structured diaphragm with a centre boss and four peninsulas (CBP structure), a high sensitivity and high linearity pressure sensor for low pressure ranges was demonstrated. The finite element analysis indicated that the CBP structure could achieve a far better performance than other typical structures for low pressure applications. In accordance with the simulation, the fabricated pressure sensor showed a sensitivity of 21.0 mV/V full‐scale output and a nonlinearity error of 0.15% full‐scale span in the pressure range of 0–5 kPa. The sensors with the CBP structure are potentially a better choice for measuring low pressures.

SignificanceBeyond its canonical functions in processes such as cell-cycle arrest, apoptosis, and senescence, the tumor suppressor p53 has been increasingly implicated in metabolism. Here, in vitro and in vivo studies establish a role for p53 in gluconeogenesis through a previously unidentified mechanism involving (i) direct activation of the gene encoding the NAD-dependent deacetylase sirtuin 6 (SIRT6), (ii) SIRT6-dependent deacetylation and nuclear exclusion of forkhead box protein O1 (FoxO1), and (iii) down-regulation of FoxO1-activated genes (G6PC and PCK1) that are rate-limiting for gluconeogenesis. These results have implications for proposed tumor-suppressor functions of p53 through regulation of metabolic pathways.
Involvement of hydrophobic amino acid residues in C7–C8 loop of Aspergillus oryzae hydrophobin RolA in hydrophobic interaction between RolA and a polyester

Published: July 2014

Abstract
Hydrophobins are amphipathic secretory proteins with eight conserved cysteine residues and are ubiquitous among filamentous fungi. The Cys3–Cys4 and Cys7–Cys8 loops of hydrophobins are thought to form hydrophobic segments involved in adsorption of hydrophobins on hydrophobic surfaces. When the fungus Aspergillus oryzae is grown in a liquid medium containing the polyester polybutylene succinate-co-adipate (PBSA), A. oryzae produces hydrophobin RolA, which attaches to PBSA. Here, we analyzed the kinetics of RolA adsorption on PBSA by using a PBSA pull-down assay and a quartz crystal microbalance (QCM) with PBSA-coated electrodes. We constructed RolA mutants in which hydrophobic amino acids in the two loops were replaced with serine, and we examined the kinetics of mutant adsorption on PBSA. QCM analysis revealed that mutants with replacements in the Cys7–Cys8 loop had lower affinity than wild-type RolA for PBSA, suggesting that this loop is involved in RolA adsorption on PBSA.

AbstractRheumatoid arthritis is an autoimmune disease associated with the recognition of self proteins secluded in arthritic joints. We generated transgenic rice seeds expressing three types of altered peptide ligands (APL) and the T cell epitope of type II collagen (CII256–271). When these transgenic rice and non-transgenic rice seeds were orally administrated to DBA/1 J mice once a day for 14 days, followed by immunization with CII, the clinical score of collagen-induced arthritis (CIA) was reduced and inflammation and erosion in the joints were prevented in mice fed APL7 transgenic rice only. IL-10 production against the CII antigen significantly increased in the splenocytes and iLN of CIA mice immunized with the CII antigen, whereas IFN-γ, IL-17, and IL-2 levels were not altered. These results suggest that IL-10-mediated immune suppression is involved in the prophylactic effects caused by transgenic rice expressing APL7.
Patient Involvement in Patient Safety: A Qualitative Study of Nursing Staff and Patient Perceptions
Authors: Bishop Andrea C. , Macdonald Marilyn 
Published: July 2014

Objectives
The risk associated with receiving health care has called for an increased focus on the role of patients in helping to improve safety. Recent research has highlighted that patient involvement in patient safety practices may be influenced by patient perceptions of patient safety practices and the perceptions of their health care providers. The objective of this research was to describe patient involvement in patient safety practices by exploring patient and nursing staff perceptions of safety.

Methods
Qualitative focus groups were conducted with a convenience sample of nursing staff and patients who had previously completed a patient safety survey in 2 tertiary hospital sites in Eastern Canada. Six focus groups (June 2011 to January 2012) were conducted and analyzed using inductive thematic analysis.

Findings
Four themes were identified: (1) wanting control, (2) feeling connected, (3) encountering roadblocks, and (4) sharing responsibility for safety. Both patient and nursing staff participants highlighted the importance of building a personal connection as a precursor to ensuring that patients are involved in their care and safety. However, perceptions of provider stress and nursing staff workload often reduced the ability of the nursing staff and patient participants to connect with one another and promote involvement.

Conclusions
Current strategies aimed at increasing patient awareness of patient safety may not be enough. The findings suggest that providing the context for interaction to occur between nursing staff and patients as well as targeted interventions aimed at increasing patient control may be needed to ensure patient involvement in patient safety.
A credibility-based Erlang mixture model for pricing crop reinsurance
Authors: Porth Lysa , Zhu Wenjun , Seng Tan Ken 
Published: July 2014

Purpose– The purpose of this paper is to address some of the fundamental issues surrounding crop insurance ratemaking, from the perspective of the reinsurer, through the development of a scientific pricing framework.Design/methodology/approach– The generating process of the historical loss cost ratio's (LCR's) are reviewed, and the Erlang mixture distribution is proposed. A modified credibility approach is developed based on the Erlang mixture distribution and the liability weighted LCR, and information from the observed data of the individual region/province is integrated with the collective experience of the entire crop reinsurance program in Canada.Findings– A comprehensive data set representing the entire crop insurance sector in Canada is used to show that the Erlang mixture distribution captures the tails of the data more accurately compared to conventional distributions. Further, the heterogeneous credibility premium based on the liability weighted LCR's is more conservative, and provides a more scientific approach to enhance the reinsurance pricing.Research limitations/implications– Credibility models are in the early stages of application in the area of agriculture insurance, therefore, the credibility models presented in this paper could be verified with data from other geographical regions.Practical implications– The credibility-based Erlang mixture model proposed in this paper should be useful for crop insurers and reinsurers to enhance their ratemaking frameworks.Originality/value– This is the first paper to introduce the Erlang mixture model in the context of agricultural risk modeling. Two modified versions of the Bühlmann-Straub credibility model are also presented based on the liability weighted LCR to enhance the reinsurance pricing framework.
