Nanoarchitectonics of Photoluminescent InP/ZnS Quantum Dots Encapsulated Silica Capsules in Physiological Solutions
Authors: Li Chunliang , Murase Norio , Li Wei
Published: October 2019

Optical properties and morphology of silica nanocapsules (ca. 40 nm of size) incorporated with multiple InP/ZnS quantum dots (QDs, ca. 3.5 nm of size) have been investigated systematically in a typical cell culture medium (Dulbecco Modified Eagle Medium, DMEM buffer) over a period of
time. The stability of silica nanocapsules with multiple QDs are found to be more robust, compared to the original aqueous pristine QDs over a period of 6 h. However, their photoluminescence efficiency is decreased after 8 h, accompanied by a change in morphology of the silica capsules. This
change in morphology is caused by the dissolution of silica by alkali, and alkali-earth cations in the buffer. Our results confirm that the silica nanocapsule surface modification occurs in aqueous solution, resulting in a change from hydroxyl to carboxyl group. We also discuss possible methods
to further increase the stability of the silica nanocapsules in physiological solutions.

Authors: Yogapriya R. , Datta K. K. R.
Published: October 2019

Designing hydrophobic-oleophilic sorbent materials have gained significant interest owing to its potential applications in self-cleaning technologies particularly oil-water separation. The crucial factors remain in the future research of designing materials with high performance hydrophobicoleophilic
properties include facile synthesis, low-density, reusability and ecofriendly. Herein, we develop porous hydrophobic-oleophilic nanoarchitecture based on 2D fluorinated graphene (FG) supported cobalt based zeolite imidazole framework (ZIF-67) by solution assisted self-assembly. The key features
of the work include in-situ growth and assembly of ZIF-67 over functionalized fluorinated graphene f-FG macrostructures, high surface area and solution processable and spray coated sponge. Methodical characterization of f-FG@ZIF-67 composites, followed by measuring water
contact angles by contact angle goniometer. Furthermore, the assessment of sorption capacity of oils and organics followed by oil recovery from oil-water mixtures, excellent chemical and physical stabilities were displayed by these hydrophobic-oleophilic composites.

Authors: Hong Ji Hwa , Jung Yongju , Kim Seok
Published: October 2019

Metallic organic frameworks (MOFs) with mixed metals has attracted attention as electrochemical energy storage material because it has high specific surface area, synergy of two metals, and a new crystal structure different from that of conventional MOF. In this study, we synthesized
MOFs, including nickel and zinc, by hydrothermal method at a time. We investigated the effect of two metal ratios on the capacitive behavior. Through the structure and morphology analysis, it was found that Ni–Zn-MOF forms a completely different crystal structure from MOF using one metal,
and found that it is a porous material. As a result of electrochemical measurements with cyclic voltammetry (CV) and galvanostatic charge–discharge (GCD), the specific capacitance of Ni–Zn-MOF 2:1 with a nickel to zinc ratio of 2:1 was 616 F g−1 at a current density
was 1 A g−1.

Authors: Liu Jia , Su Guo-Dong , Wang Zhou
Published: October 2019

Magnetic Ni0.3Mg0.3Zn0.4Fe2O4 nanoparticles were synthesized by the absolute alcohol combustion method. The morphology, microstructure, and composition of as-prepared Ni0.3Mg0.3Zn0.4Fe2O4
nanoparticles were characterized by several techniques: the vibrating sample magnetometer (VSM), the scanning electron microscopy (SEM), the X-ray diffraction (XRD), and the energy dispersive spectroscopy (EDS). The experimental results showed that the calcination temperature and the solvent
volume were the crucial factors for the synthesis of the magnetic Ni0.3Mg0.3Zn0.4Fe2O4 nanoparticles. The adsorption performance of Ni0.3Mg0.3Zn0.4Fe2O4 nanoparticles for congo red
(CR) was investigated. The model of pseudo-second-order kinetic was optimal matching for obtaining the parameters of adsorption CR in the initial range of 100–400 mg/L−1, while, the isotherm data of CR onto Ni0.3Mg0.3Zn0.4Fe2O4
nanoparticles could conform to the Temkin model owing to the values of the square deviations, which revealed that the adsorption of CR onto Ni0.3Mg0.3Zn0.4Fe2O4 nanoparticles at room temperature was the monolayer and multilayer adsorption
mechanism.

Published: October 2019

The removal of heavy-metal ions from wastewater is an important objective from a public-health perspective, and chelating agents can be used to achieve this aim. Herein, we report the synthesis of mesoporous carbon as a chelating polymer host using nanoarchitectonics approach. Carboxymethylated
polyethyleneimine, a chelating polymer, was incorporated into the mesopore walls of mesoporous carbon to create a polymer-mesoporous-carbon composite. Nitrogen adsorption– desorption experiments and scanning electron microscopy (SEM) were used to illustrate the structural advantages
of the composite. Co2+ adsorption by the composite material was examined using cobalt nitrate solutions at pH 3. The study revealed that the Co2+-absorption data are most closely modeled by the Langmuir isotherm. The maximum adsorption capacity, calculated by linear regression,
was determined to be about 40 mg-Co/g-composite at pH 3. The composite exhibited about a six-times higher adsorption capacity toward a dilute Co solution (12.5 ppm) than that of the pristine mesoporous carbon. In addition, the composite showed a substantially higher distribution coefficient
(Kd = 1.54×105) compared to that (Kd = 2.05×102) of the mesoporous carbon. Overall, we expect that the mesoporous composite, with its large mesopores (~20 nm), will be in high demand for adsorption applications.

In this study, we investigated water-dispersible surface modification for size- and shape-controlled fullerene nanoparticles (C60P) based on a condensation reaction with di-amino alkane. This modification provided for water dispersibility of C60P and the capability
for secondary modification as well. The resultant C60P particles have several useful physical properties: water-dispersibility for ease of injection; fluorescence for detection and quantification; and a characteristic morphology to assist identification. These properties will widely
extend the applications of these particles, especially into the biological fields of bioimaging and drug delivery.

Authors: Xu Juan , Gao Biao , Huo Kai-Fu , Chu Paul K.
Published: October 2019

As a new type of energy-storage devices, lithium-ion capacitors (LICs) are designed to deliver high energy densities, high power densities, and long lifespan by integrating the battery-type anodes and capacitor-type cathodes. Achieving high energy and power density simultaneously is
the challenge of LICs, which is mainly determined by the cathode and anode materials. In this mini-review, basing on the working principles of LICs, we discuss the categories and electrochemical performance as well as the matching strategies of the cathodes and anodes. In anodes, we focus
on summarizing the structural design of the prelithiation transition-metal compounds based materials. In cathodes, we emphasize discussing the fabrication and morphology adjustment of the low dimensional carbon materials. Finally, the prospects and challenges confronting future research and
development of LICs are provided.

Published: October 2019

The Flash Flood and Intense Rainfall (FFaIR) Experiment developed within the Hydrometeorology Testbed (HMT) of the Weather Prediction Center (WPC) is a pseudo-operational platform for participants from across the weather enterprise to test emerging flash flood forecasting tools and issue experimental forecast products. This study presents the objective verification portion of the 2017 edition of the experiment, which examines the performance from a variety of guidance tools (deterministic models, ensembles, and machine-learning techniques) and the participants’ forecasts, with occasional reference to the participants’ subjective ratings. The skill of the model guidance used in the FFaIR Experiment is evaluated using performance diagrams verified against the Stage IV analysis. The operational and FFaIR Experiment versions of the excessive rainfall outlook (ERO) are evaluated by assessing the frequency of issuances, probabilistic calibration, Brier skill score (BSS), and area under relative operating characteristic (AuROC). An ERO first-guess field called the Colorado State University Machine-Learning Probabilities method (CSU-MLP) is also evaluated in the FFaIR Experiment. Among convection-allowing models, the Met Office Unified Model generally performed optimally throughout the FFaIR Experiment when using performance diagrams (at the 0.5- and 1-in. thresholds; 1 in. = 25.4 mm), whereas the High-Resolution Rapid Refresh (HRRR), version 3, performed best subjectively. In terms of subjective and objective ensemble scores, the HRRR ensemble scored optimally. The CSU-MLP overpredicted lower risk categories and underpredicted higher risk categories, but it shows future promise as an ERO first-guess field. The EROs issued by the FFaIR Experiment forecasters had improved BSS and AuROC relative to the operational ERO, suggesting that the experimental guidance may have aided forecasters.
Fundamental Behavior of ENSO Phase Locking
Authors: Chen Han-Ching , Jin Fei-Fei
Published: October 2019

El Niño–Southern Oscillation (ENSO) events tend to peak at the end of the calendar year, a phenomenon called ENSO phase locking. This phase locking is a fundamental ENSO property that is determined by its basic dynamics. The conceptual ENSO recharge oscillator (RO) model is adopted to examine the ENSO phase-locking behavior in terms of its peak time, strength of phase locking, and asymmetry between El Niño and La Niña events. The RO model reproduces the main phase-locking characteristics found in observations, and the results show that the phase locking of ENSO is mainly dominated by the seasonal modulation of ENSO growth/decay rate. In addition, the linear/nonlinear mechanism of ENSO phase preference/phase locking is investigated using RO model. The difference between the nonlinear phase-locking mechanism and linear phase-preference mechanism is largely smoothed out in the presence of noise forcing. Further, the impact on ENSO phase locking from annual cycle modulation of the growth/decay rate, stochastic forcing, nonlinearity, and linear frequency are examined in the RO model. The preferred month of ENSO peak time depends critically on the phase and strength of the seasonal modulation of the ENSO growth/decay rate. Furthermore, the strength of phase locking is mainly controlled by the linear growth/decay rate, the amplitude of seasonal modulation of growth/decay rate, the amplitude of noise, the SST-dependent factor of multiplicative noise, and the linear frequency. The asymmetry of the sharpness of ENSO phase locking is induced by the asymmetric effect of state-dependent noise forcing in El Niño and La Niña events.
On the Superposition of Mean Advective and Eddy-Induced Transports in Global Ocean Heat and Salt Budgets

Published: October 2019

Ocean thermal expansion is a large contributor to observed sea level rise, which is expected to continue into the future. However, large uncertainties exist in sea level projections among climate models, partially due to intermodel differences in ocean heat uptake and redistribution of buoyancy. Here, the mechanisms of vertical ocean heat and salt transport are investigated in quasi-steady-state model simulations using the Australian Community Climate and Earth-System Simulator Ocean Model (ACCESS-OM2). New insights into the net effect of key physical processes are gained within the superresidual transport (SRT) framework. In this framework, vertical tracer transport is dominated by downward fluxes associated with the large-scale ocean circulation and upward fluxes induced by mesoscale eddies, with two distinct physical regimes. In the upper ocean, where high-latitude water masses are formed by mixed layer processes, through cooling or salinification, the SRT counteracts those processes by transporting heat and salt downward. In contrast, in the ocean interior, the SRT opposes dianeutral diffusion via upward fluxes of heat and salt, with about 60% of the vertical heat transport occurring in the Southern Ocean. Overall, the SRT is largely responsible for removing newly formed water masses from the mixed layer into the ocean interior, where they are eroded by dianeutral diffusion. Unlike the classical advective–diffusive balance, dianeutral diffusion is bottom intensified above rough bottom topography, allowing an overturning cell to develop in alignment with recent theories. Implications are discussed for understanding the role of vertical tracer transport on the simulation of ocean climate and sea level.
Assessment of the Sea Surface Temperature Predictability Based on Multimodel Hindcasts
Authors: Zhang Shouwen , Jiang Hua , Wang Hui
Published: October 2019

Based on historical forecasts of four individual forecasting systems, we conducted multimodel ensembles (MME) to predict the sea surface temperature anomaly (SSTA) variability and assessed these methods from a deterministic and probabilistic point of view. To investigate the advantages and drawbacks of different deterministic MME methods, we used simple averaged MME with equal weighs (SCM) and the stepwise pattern projection method (SPPM). We measured the probabilistic forecast accuracy by Brier skill score (BSS) combined with its two components: reliability (Brel) and resolution (Bres). The results indicated that SCM showed a high predictability in the tropical Pacific Ocean, with a correlation exceeding 0.8 with a 6-month lead time. In general, the SCM outperformed the SPPM in the tropics, while the SPPM tend to show some positive effect on the correction when at long lead times. Corrections occurred for the spring predictability barrier of ENSO, in particular for improvements when the correlation was low or the RMSE was large using the SCM method. These qualitative results are not susceptible to the selection of the hindcast periods, it is as a rule rather by chance of these individual systems. Performance of our probabilistic MME was better than the Climate Forecast System version2 (CFSv2) forecasts in forecasting COLD, NEUTRAL, and WARM SSTA categories for most regions, mainly due to the contribution of Brel, indicating more adequate ensemble construction strategies of the MME system superior to the CFSv2.
Tornado Fatalities: An Environmental Perspective
Authors: Anderson-Frey Alexandra K. , Brooks Harold
Published: October 2019

Deadly tornadoes are rare events, but that level of rarity varies with many factors. In this work, we summarize and update past research on tornado fatalities, and also discuss the environments of deadly tornadoes both from the perspective of proximity soundings (i.e., point-based) and self-organizing maps (i.e., two-dimensional). In our study of 16 232 tornado events from 2003 to 2017, we find that deadly tornadoes are disproportionately likely to have high (E)F-scale ratings, to have right-moving supercell parent storm modes (deadly QLCS tornadoes are exceptionally rare and tend to result in only one death when they do occur), and to occur during the winter and spring. Warning skill is generally higher for deadly tornadoes than for nondeadly tornadoes: 87% of deadly tornadoes were warned in advance, and nearly 95% of tornado deaths occurred within an active warning. The same environments are warned well for both deadly and nondeadly tornadoes, but the deadly tornadoes tend to occur in environments that are less conducive to weaker (E)F0–1 tornadoes. We identify four prototypical deadly tornado scenarios using self-organizing maps, ranging from marginal environments resulting in relatively few fatalities to major deadly outbreak events. Overall results indicate that the most dangerous tornadoes (i.e., those with high numbers of deaths per deadly tornado) also generally occur in environments and under conditions in which warning skill is high. While, generally speaking, the correct storms are being warned, we include some recommendations for additional research and further improvement.
Factors Influencing the Performance of Regression-Based Statistical Postprocessing Models for Short-Term Precipitation Forecasts
Authors: Li Wentao , Duan Qingyun , Wang Quan J.
Published: October 2019

Statistical postprocessing models can be used to correct bias and dispersion errors in raw precipitation forecasts from numerical weather prediction models. In this study, we conducted experiments to investigate four factors that influence the performance of regression-based postprocessing models with normalization transformations for short-term precipitation forecasts. The factors are 1) normalization transformations, 2) incorporation of ensemble spread as a predictor in the model, 3) objective function for parameter inference, and 4) two postprocessing schemes, including distributional regression and joint probability models. The experiments on the first three factors are based on variants of a censored regression model with conditional heteroscedasticity (CRCH). For the fourth factor, we compared CRCH as an example of the distributional regression with a joint probability model. The results show that the CRCH with normal quantile transformation (NQT) or power transformation performs better than the CRCH with log–sinh transformation for most of the subbasins in Huai River basin with a subhumid climate. The incorporation of ensemble spread as a predictor in CRCH models can improve forecast skill in our research region at short lead times. The influence of different objective functions (minimum continuous ranked probability score or maximum likelihood) on postprocessed results is limited to a few relatively dry subbasins in the research region. Both the distributional regression and the joint probability models have their advantages, and they are both able to achieve reliable and skillful forecasts.
Surgical Management of Vestibular Schwannoma: Practice Pattern Analysis via NSQIP
Authors: Patel Vijay A. , Dunklebarger Mitchell , Banerjee Kalins , Shokri Tom , Zhan Xiang , Isildak Huseyin
Published: October 2019

Objective:

Characterize current perspectives in the surgical management of vestibular schwannoma (VS) to guide otolaryngologists in understanding United States practice patterns.

Methods:

A retrospective analysis of ACS-NSQIP database was performed to abstract all patients from 2008 to 2016 who underwent VS resection using ICD-9/10 codes 225.1 and D33.3, respectively. The specific surgical approach employed was identified via CPT codes 61520, 61526/61596, and 61591, which represent retrosigmoid (RS), translabyrinthine (TL) and middle cranial fossa (MCF) approaches, respectively. Analyzed outcomes include general surgical complications, total length of stay, and reoperation.

Results:

A total of 1671 VS cases were identified, 1266 (75.7%) were RS, 292 (17.5%) were TL, and 114 (6.8%) were MCF. The annual number of cases increased over the study period from 15 to 375, which is chiefly attributed to increased institutional participation in ACS-NSQIP. Perioperative variables including BMI ( P < .001), ASA class ( P = .004), ethnicity ( P = .008), operative time ( P < .001), and reoperation ( P < .001) were found to be statistically significant between cohorts. Increased utilization of RS approach was consistent over the entire study period, with significantly more RS performed than either TL or MCF. Finally, a statistically significant difference with respect to general surgical complication rates was not noted between surgical approaches.

Conclusions:

There is increased employment of RS approach for the operative management of VS, which likely is the result of increased reliance on both stereotactic radiosurgery and observation as alternative treatment strategies.
Consensus-based decision making in non-linearly multi-coupled IoT networked SLAM operations
Authors: Rai Ankush , Kannan R Jagadeesh
Published: October 2019

This study presents a modeling method for control system of multi-coupled non-linear cyber physical system with the help of second-order dynamics of communicating membrane system of neuronal population based on a population coding algorithm. Here, the communicating membrane system is modeled based on several IoT devices connected in peer to peer form and the theory of fractional differential equations is as governing function over them. Here, the difficulty is in developing a collaborative learning algorithm for finding collaborative key points within high-dimensional decision space. In order to overcome such a problem, a gradient-based method is required to enable distributed control and collaborative decision making. Here, at every interval of the sampling time, all the subsystems are optimally synchronized in P population system by multiset-rewriting rules including the effect of symport/antiport systems. This is an interesting technical problem, related to the borderline between universality and non-universality of continuity of distributed coupling of multi-coupled control system. The presented study discusses the experimental proof of the algorithmic framework and model for SLAM operation. The consensus architecture in this domain will enable the development of evolving architecture of a non-linear cyber physical system. The close loop stability and the recursive feasibility of the evolved architecture are also studied.

Published: October 2019

This work investigates the influence of fiber surface profile and roughness to fiber–matrix interfacial properties. A series of the push-out test is performed using specimens with different fiber surface profile and roughness. Numerical simulation is then carried out by employing a finite element method to fit the experimental data. The model contains an indenter which pushes in a single fiber from the matrix, while the cohesive zone model is applied to represent the interface resulting in force–displacement curves. Our results suggest that continuous cavities formed in graphite-based fiber may not be beneficial to interfacial properties since it can accelerate a debonding process along with the interface. In contrast, scattered cavities on the fiber surface create strong mechanical locking, which increases the interfacial strength. These results broaden the understanding of the surface profile, which would shed light on a new perspective in designing composite structures.
Crimea come what may: Do economic sanctions backfire politically?
Authors: Alexseev Mikhail A , Hale Henry E
Published: October 2019

Do international economic sanctions backfire politically, resulting in increased rather than decreased domestic support for targeted state leaders? Backfire arguments are common, but researchers have only recently begun systematically studying sanctions’ impact on target-state public opinion, not yet fully unpacking different possible backfire mechanisms. We formulate backfire logic explicitly, distinguishing between ‘scapegoating’ and ‘rallying’ mechanisms and considering the special case of ‘smart sanctions’ aimed at crony elites rather than the masses. We test five resulting hypotheses using an experimental design and pooled survey data spanning the imposition of sanctions in one of the most substantively important cases where the backfire argument has been prominent: Western sanctions on Russia in 2014. We find no evidence of broad sanctions backfire. Instead, sanctions have forced Russia’s president to pay a political price. But this price has been low compared to the massive political benefits we document arising from the sanctions-triggering event, the Crimea annexation. Moreover, hidden by aggregate figures are signs of a ‘backlash of the better-off’ by which ‘smart’ sanctions turn economic well-being from a predictor of opposition into a predictor of regime support.
An Analysis of Statutes Criminalizing Correctional Officer Sexual Misconduct With Inmates
Authors: Kowalski Melissa A. , Mei Xiaohan , Turner John R. , Stohr Mary K. , Hemmens Craig
Published: October 2019

The 2003 Prison Rape Elimination Act (PREA) mandates that U.S. state correctional systems regulate and reduce staff-on-inmate sexual misconduct in state correctional facilities. As data on correctional officer sexual misconduct are limited and its legal definition varies across states, this study utilized statutory analysis to document how staff sexual misconduct is defined and how it is punished across state correctional systems. The most notable finding is that although all 50 states have statutes designed to protect incarcerated persons from being sexually victimized by correctional staff, they are far from uniform.
The Privileged Sex? An Examination of Gendered Beliefs and Well-Being in Evangelical Men
Authors: Horrell Kerry E. , Hall M. Elizabeth Lewis , Anderson Tamara L. , McMartin Jason
Published: October 2019

The current study sought to investigate the relationship between benevolent sexism, gender role ideologies, and well-being in Evangelical men. Despite recent research that has established a relationship between restrictive gender beliefs and negative outcomes for women, few studies have addressed the relationship between these variables in men. Furthermore, Evangelical men’s specific experience has not been explored, in spite of religiosity’s association with these beliefs. Therefore, this study directly assessed relationship between well-being and two kinds of restrictive gender beliefs (i.e., benevolent sexism and traditional gender role ideology) in a sample of Evangelical men. Results showed that endorsement of benevolent sexism and traditional gender role ideology were related to lower levels of eudaimonic well-being for this population. Additionally, it was found that different patterns of relationship exist between restrictive gender beliefs and the two kinds of well-being: eudaimonic well-being (e.g., purpose and meaning) and hedonic well-being (e.g., pleasure and satisfaction) for this population. Specifically, the negative relationships with eudaimonic well-being were stronger than the negative relationships with aspects of hedonic well-being.

Authors: Zucchini Simone , Brancatelli Silvia , Piccinato Alice , Marcuzzo Alberto Vito , Bianchi Max , Tirelli Giancarlo
Published: October 2019

Dorsal hump reduction is a crucial point of rhinoplasty, as it has a great impact on the final shape of nasal pyramid. Depending on morphological features of the hump, its removal is usually obtained by the use of an osteotome or a rasp. In our study, we describe a closed rhinoplasty technique performed in 2 groups of patients: the only difference between the groups is the surgical tools used during the dorsal hump removal phase (rasp vs the 5-mm osteotome).We used 2 questionnaires of quality of life (QoL), Nasal Obstruction Symptom Evaluation (NOSE), and Rhinoplasty Outcome Evaluation (ROE) questionnaire, to evaluate postoperative outcome (6 months after surgery).Closed rhinoplasty was performed in 107 patients. Dorsal hump removal was carried out with rasp on 35 patients; while in 72 cases, it was performed using a 5-mm osteotome. All the patients were given 2 copies of NOSE and ROE questionnaires (1 month before surgery and 6 months after surgery) to evaluate postoperative QoL. In our study emerged that the use of osteotome in dorsal hump reduction is associated with a better aesthetic outcome (evaluated by analyzing patients QoL with ROE questionnaire) without any difference between the 2 groups in terms of functional outcome (expressed by NOSE questionnaire), major and minor complications and surgical procedure duration.
Understanding Self-Respect and Its Relationship to Self-Esteem
Authors: Clucas Claudine
Published: October 2019

The concept of self-respect has received little attention in the psychological literature and is not clearly distinguished from self-esteem. The present research sought to empirically investigate the bases of self-respect by manipulating adherence to morals together with interpersonal appraisals (IAs), or task-related competence, in hypothetical scenarios (Studies 1a and 1b) and a situation participants relived (Studies 2 and 3). Participants’ levels of state self-respect and self-esteem were measured. Studies 1 to 3 found main effects of adherence to morals on self-respect, with self-respect mediating the effect of adherence to morals on self-esteem, but little support for competence and IAs directly influencing self-respect. Self-respect uniquely contributed to anticipated/felt self-esteem alongside competence or IAs. The pattern of results supports the conceptualization of self-respect as a component of self-esteem associated with morally principled conduct, distinct from performance and social self-esteem. The findings have implications for our understanding of self-esteem and moral behavior.
Examining differential trajectories of engagement over the transition to secondary school: The role of perceived control
Authors: Lemos Marina S. , Gonçalves Teresa , Cadima Joana
Published: October 2019

The present study was particularly interested in identifying resilient trajectories of engagement, and analyzing their association with student’s motivation, specifically, their perceived control. In a longitudinal study following 391 students across three measurement points, encompassing the transition from 9th to 10th grade (from basic to secondary school), students’ beliefs (control, effort capacity, and ability capacity beliefs), engagement, and academic achievement were assessed. Consistent with previous research, an overall decline in levels of engagement was found over this time, associated with perceived control. To uncover alternative pathways, latent class growth analysis was used, and three groups of students were identified based on their distinct engagement trajectories: (1) students whose engagement started high but decreased (high-decreasing engagement), (2) students who started at average levels and declined (average-decreasing engagement), and (3) students whose engagement started low but then increased (low-increasing engagement). Comparison of the three groups demonstrated that control beliefs play a critical role in reducing the normative rate of decline in engagement. The recovery trajectory (low-increasing engagement), which is of particular interest, showed smaller declines in control beliefs. Findings also suggest that effort capacity beliefs seem to protect engagement in the face of the challenges this group of lower performing students are likely to encounter. The emergence of the three distinct engagement groups is of special interest as it shows positive, counter-normative changes in engagement trajectories. The observed changes in engagement, motivation, and achievement of the potentially at-risk students (low-increasing engagement group) suggest that these students may be especially sensitive to a supportive and engaging academic environment.
Five Kurosawas and a (de)construction of the Orient
Authors: Huttunen Miia
Published: October 2019

In 1959, UNESCO published a catalogue of Eastern films suitable for Western audiences, titled ‘Orient. A Survey of Films Produced in Countries of Arab and Asian Culture’. The aim of the catalogue was to familiarise Western audiences with Eastern cultures through cinema. The catalogue lists seven general characteristics of Eastern cinema to distinguish it from its Western counterpart and to provide ready-made interpretations of the essential characteristics of the Eastern world. Of the 139 feature films listed in the catalogue, five were directed by Kurosawa Akira – the biggest number of films by a single director. This article provides an analysis of the five Kurosawa films within the frame provided by the characterisations in the catalogue in the political framework of World War II and its aftermath. Reading the cultural differences listed in the catalogue as a means of constructing the East in Western eyes, the article suggests UNESCO’s world was defined neither in terms of the contemporaneous geopolitical polarisation of the Cold War nor the ongoing decolonisation process. Instead, the catalogue served the purpose of proposing a cultural intervention in geopolitics, providing a reimagining of political realities constructed on a cultural basis and given a concrete form through cinema.
Association between FSAP 1601G>A polymorphism and venous thromboembolism risk: A meta-analysis
Authors: Da Li , Jiahui Zhao , Xiaoqiang Li
Published: October 2019

Objective

Previous several studies have shown that factor VII-activating protease (FSAP) gene 1601G>A polymorphism is related to the occurrence of venous thromboembolism, but the results are inconsistent and controversial. Therefore, we conducted a meta-analysis to explore the association between FSAP 1601G>A polymorphism and venous thromboembolism susceptibility.

Methods

We managed a systematic literature search through Pubmed, Embase, Web of Science, China National Knowledge Infrastructure, and WanFang databases to collect research data related to FSAP gene 1601G>A polymorphism and susceptibility to venous thromboembolism published before May 2019. Data analysis was performed through Revman 5.3 and Stata 12.0 software, the pooled odd ratios and 95% confidence intervals were calculated. Additionally, the sensitivity analysis and publication bias assessment were also performed.

Results

A total of seven case–control studies were included and evaluated, including 2411 venous thromboembolism cases and 2850 controls. The meta-analysis results revealed that the FSAP 1601G>A mutation is associated with venous thromboembolism risk, and statistically significance was observed under three genetic comparison models (A: G, odds ratio: 1.33, 95% confidence interval: 1.07–1.66; GA: GG, odds ratio: 1.34, 95% confidence interval: 1.06–1.68; and GA + AA: GG, odds ratio: 1.33, 95% confidence interval: 1.06–1.66).

Conclusion

This study demonstrated that the FSAP 1601G>A polymorphism may be associated with venous thromboembolism susceptibility.
Early-stage 11C-Flumazenil PET predicts day-14 selective neuronal loss in a rodent model of transient focal cerebral ischemia

Published: October 2019

Predicting tissue outcome early after stroke is an important goal. MRI >3 h accurately predicts infarction but is insensitive to selective neuronal loss (SNL). Previous studies suggest that chronic-stage 11 C-flumazenil PET (FMZ-PET) is a validated marker of SNL in rats, while early-stage FMZ-PET may predict infarction. Whether early FMZ-PET also predicts SNL is unknown. Following 45-min distal MCA occlusion, adult rats underwent FMZ-PET at 1 h and 48 h post-reperfusion to map distribution volume (VT), which reflects GABA-A receptor binding. NeuN immunohistochemistry was performed at Day 14. In each rat, VT and %NeuN loss were determined in 44 ROIs spanning the hemisphere. NeuN revealed isolated SNL and cortical infarction in five and one rats, respectively. In the SNL subgroup, VT-1 h was mildly reduced and only weakly predicted SNL, while VT-48 h was significantly increased and predicted SNL both individually ( p < 0.01, Kendall) and across the group ( p < 0.001), i.e. the higher the VT, the stronger the SNL. Similar correlations were found in the rat with infarction. Our findings suggest GABA-A receptors are still present on injured neurons at the 48 h timepoint, and the increased 48 h VT observed here is consistent with earlier rat studies showing early GABA-A receptor upregulation. That FMZ binding at 48 h was predictive of SNL may have clinical implications.
Calculational model for first-mode eigenfrequency of a semi-guy-wired vertical-axis wind turbine tower
Authors: Möllerström Erik , Ottermo Fredric
Published: October 2019

A simple model for accounting for tower mass when estimating the first-mode eigenfrequency of a semi-guy-wired tower has been derived. This extends previous work where an analytical model of the semi-guy-wired tower of a 200-kW vertical-axis wind turbine was developed. The model was primarily used to estimate the eigenfrequencies as a result of adding guy wires to a free-standing tower (thus creating a semi-guy-wired setup). However, a weakness with the model was that the tower mass was accounted for in a rough way that essentially ignored the guy wires, which gave a larger-than-necessary error. In this work, an effective top mass, that takes into account the tower mass and the constraints from the guy wires, is derived to achieve a higher accuracy when estimating the first-mode eigenfrequency. This, together with the earlier models, gives a more complete method to estimate the eigenfrequencies for a semi-guy-wired wind turbine.
Recurrent activity-induced headache associated with posttraumatic dural adhesion of the middle meningeal artery: A case report
Authors: Elisevich Lee , Singer Justin , Walsh Meggen
Published: October 2019

Background

The middle meningeal artery is surrounded by a plexus of afferent fibers shown to be involved in the progression of some forms of headache, especially migraine. Posttraumatic headache disorders sharing characteristics with migraine and involving the middle meningeal artery are not readily available in the literature.

Case description

This report describes a posttraumatic headache disorder in a middle-aged woman in which the causative factor proved to be a pathology of the left middle meningeal artery that resulted from trauma. Her pain could be triggered by moderate accelerative changes, occurring in the left frontotemporal region, and shared characteristics with migraine. Resection of a portion of the left middle meningeal artery has completely eliminated her pain syndrome.

Conclusion

This case further elucidates associations between the middle meningeal artery and headache. The presentation of posttraumatic headache sharing characteristics with migraine should suggest the possibility of a middle meningeal artery abnormality.
‘Every child that’s born alive . . .’ — Response to Regine Scholz and Earl Hopper
Authors: Tubert-Oklander Juan
Published: October 2019

This is my response to Regine Scholz’s and Earl Hopper’s commentaries on my 2019 Foulkes Lecture. Here I discuss Foulkes’ concept of the matrix and the limits of his metaphor of individuals as knots in the communicational network, as well as the opposition and mutual relation between classical psychoanalysis and group analysis, on the one hand, and the relational perspective on the other. I also emphasize the urgent need to revise our underlying assumptions that contradict the discoveries of analysis, in order to develop a new interdisciplinary and all-inclusive paradigm of the human being.
Human Herpesvirus-6 may be Neurologically Injurious in Some Immunocompetent Children
Authors: You Su Jeong
Published: October 2019

Purpose:

Human herpesvirus 6 (HHV-6) can infect the central nervous system in immunocompromised individuals. Less is known, however, about HHV-6 infection in immunocompetent patients. This study evaluated the neurologic features and prognosis of HHV-6 infection in immunocompetent patients.

Methods:

The medical records of patients aged 1 month to 18 years who underwent cerebrospinal fluid examinations and were tested for 6 viruses, including HHV-6, by multiplex polymerase chain reaction were evaluated retrospectively.

Results:

During the study period, 252 children were included. None had underlying disease and all were immunocompetent. Their mean age at diagnosis was 40.98 ± 47.65 months. Of these 252 patients, 144 (57.1%) were diagnosed with meningitis, 84 (33.3%) with febrile seizure not induced by meningitis, and 24 (9.5%) with encephalitis. Of the 9 patients positive for HHV-6, 3 (33.3%) had encephalitis, 3 (33.3%) had meningitis, 1 (11.1%) had complex febrile seizure, and the other 2 patients had fever alone. Outcomes were worse in the seizure group (Fisher exact test, P = .048), especially in patients with status epilepticus (Fisher exact test, P = .012), than in the other groups. Encephalitis patients with and without HHV-6 differed significantly in age (24.0 ± 10.8 vs 63.4 ± 47.7 months, t-test P < .05), with status epilepticus being more frequent in those with HHV-6 (Fisher exact test, P = .010). All 3 encephalitis patients positive for HHV-6 had neurologic sequelae; 2 who had mild sequelae were treated with antiviral agents and intravenous immunoglobulin.

Conclusions:

HHV-6 may not be completely benign in immunocompetent children. It can be associated with encephalitis and poor prognosis.
Performance of Critical Care Outcome Prediction Models in an Intermediate Care Unit
Authors: Brusca Rebeccah M. , Simpson Catherine E. , Sahetya Sarina K. , Noorain Zeba , Tanykonda Varshitha , Stephens R. Scott , Needham Dale M. , Hager David N.
Published: October 2019

Background:

Intermediate care units (IMCUs) are heterogeneous in design and operation, which makes comparative effectiveness studies challenging. A generalizable outcome prediction model could improve such comparisons. However, little is known about the performance of critical care outcome prediction models in the intermediate care setting. The purpose of this study is to evaluate the performance of the Acute Physiology and Chronic Health Evaluation version II (APACHE II), Simplified Acute Physiology Score version II (SAPS II) and version 3 (SAPS 3), and Mortality Probability Model version III (MPM0III) in patients admitted to a well-characterized IMCU.

Materials and Methods:

In the IMCU of an academic medical center (July to December 2012), the discrimination and calibration of each outcome prediction model were evaluated using the area under the receiver–operating characteristic and Hosmer-Lemeshow goodness-of-fit test, respectively. Standardized mortality ratios (SMRs) were also calculated.

Results:

The cohort included data from 628 unique IMCU admissions with an inpatient mortality rate of 8.3%. All models exhibited good discrimination, but only the SAPS II and MPM0III were well calibrated. While the APACHE II and SAPS 3 both markedly overestimated mortality, the SMR for the SAPS II and MPM0III were 0.91 and 0.91, respectively.

Conclusions:

The SAPS II and MPM0III exhibited good discrimination and calibration, with slight overestimation of mortality. Each model should be further evaluated in multicenter studies of patients in the intermediate care setting.
Between Surveillance and Sousveillance: Or, Why Campus Police Feel Vulnerable Precisely Because They Gain Power
Authors: Inoue Masamichi
Published: October 2019

Utilizing historical and ethnographic data, this article explicates a thesis that involves a paradox—campus police feel vulnerable as the “surveyed” precisely because they gain power as the “surveyor.” Toward this end, first, I identify a dramatic change in the status and function of campus police from watchmen to law enforcement professionals in the 1960s-1970s as a key historical context in which this paradox emerged. Then, I ethnographically explore forms this paradox has taken at the level of consciousness-behavior of campus officers. Attention is paid to how digital technologies of the twenty-first century transform campus policing, a process that redefines the relationship between the state and civil society and normalizes “watching” as a basic mechanism of new governance. I consider political and theoretical implications of new governance and the role writing can play in ethnographic studies of police to elucidate it.
“You’re a Sociologist, I Am Too . . . ”: Seducing the Ethnographer, Disruption, and Ambiguity in Fieldwork with (Mostly) Undocumented Youth
Authors: Rodriguez Sophia
Published: October 2019

The article is about a set of methodological disruptions that occur in ethnographic fieldwork and what these disruptions mean for ethnographic studies, including analysis, representation of data, and experiences of the ethnographic self. This article documents the process of a minoritized high school youth, Queen, entering the research space and the emergent relations among Queen and Latinx undocumented youth. Drawing on Jacques Derrida’s analytics, I theorize disruption as a core concept in this particular experience of engaging in fieldwork as part of a multisite critical ethnography. Presenting three frames of disruption—relating to the research space, analyses and findings, and the ethnographic self—I complicate who gets included and excluded from a study and the implications for relational ethnics in ethnographic fieldwork. Ultimately, I argue that our methodological practices and selves need to be disrupted in order to enhance our views of who/what gets included/excluded during our fieldwork.
