Optimization of Subsidy Policy for New Energy Automobile Industry in China Based on an Integrated Fuzzy‐AHP‐TOPSIS Methodology
Authors: Wang Xiaojia , Song Yiming , Zhang Xuan , Liu Hui
Published: November 2019

With the continuous tension of the international energy supply and the increasing appeal of the global environmental protection, the development of the new energy vehicle industry has attracted international attention. In order to support the development of new energy automobile production, China has frequently issued support policies. However, the problem of subsidy fraud has been exposed. Therefore, in order to help the healthy development of China’s new energy automobile industry and reduce the risk of subsidy fraud, this paper investigates 15 representative new energy auto enterprises in China and independently evaluates their performance from three aspects. We first use triangular fuzzy numbers (TFNs) to simulate an uncertain decision environment and more closely reflect the decision maker’s thinking model; we then propose an analytic hierarchy process (AHP)‐technique for order preference by similarity to an ideal solution (TOPSIS) method based on fuzzy data to rank 15 enterprises. Finally, according to the performance of enterprises, we propose differentiated subsidy policy recommendations. The model proposed in this paper takes into account the uncertainty of subjective evaluation so as to increase the credibility of the results. At the same time, the model can also be applied in other industries.
GMM‐MUD: An Effective Multiuser Detection Algorithm for DS‐UWB‐Based Space Formation Flying Systems
Authors: Ma Bo , Wu Mingyang , Wu Zhilu , Yin Zhendong , Shen Tao
Published: November 2019

In this paper, an effective multiuser detection (MUD) is proposed for direct sequence ultrawideband‐ (DS‐UWB‐) based space formation flying systems. The proposed method called GMM‐MUD is based on Gaussian mixture models (GMMs) to suppress multiple access interference. The GMM describes probability distributions of the hypothesis testing problem which is used for bit classification. To reveal the difference between correct bits and error bits, the preprocessing operation applies a mapping function based on optimal multiuser detection. The parameters of GMM are estimated by using expectation‐maximization (EM) algorithm. EM algorithm employs iterative operation to simplify the complexity of maximum likelihood estimation method and considers the mapping values of received bits as the observations. Simulation results demonstrate that the proposed GMM‐MUD algorithm achieves good performances in terms of bit error rate performance, user capacity, and near‐far resistance. Moreover, the computational complexity is low enough for space formation flying applications.
Microdebrider-Assisted Rhinophyma Excision
Authors: Abushaala Abdulaziz , Stavrakas Marios , Khalil Hisham
Published: November 2019

Rhinophyma represents a progressive deformity of the nose which leads to cosmetic disfigurement and has a significant impact on the patient’s quality of life. This pathological entity originates from hyperplasia of sebaceous gland tissue, connective tissue, and vessels of the nose and is associated with rosacea and more specifically, stage III rosacea. Surgical treatment is the method of choice. We present five cases of rhinophyma that we treated with microdebrider-assisted excision. The procedure was divided in two main steps: scalpel excision of the main bulk of the rhinophyma and then further contouring with the microdebrider. All patients had weekly follow-up for the first four weeks, and then three-monthly. All patients had uneventful recovery and satisfactory cosmetic outcomes. No postoperative infections or other complications were reported in our case series. The use of the microdebrider reduces the operating time, preserves the islands of skin regeneration, and allows finer manipulations than the standard scalpel techniques. Microdebrider-assisted rhinophyma excision is a safe approach, with good aesthetic results. Larger series of patients need to be examined in order to establish the value of the method.

Published: November 2019

PANI/chitosan composite and a ternary composite comprising of PANI, chitosan, and reduced graphene oxide have been successfully synthesised and characterised using FTIR and UV-VIS spectroscopy. Optical constants of the composites were extracted from the UV-VIS spectra. The extracted parameters were applied in the simulation of a surface plasmon resonance (SPR) biosensor functionalised with PANI/chitosan and ternary composites. The aim was to explore the applicability of the composite-based SPR sensor in the detection of low-concentration acetone vapour within the range of 1.8 ppm–5.0 ppm for diabetes monitoring and screening. The functionalization of the SPR sensor with the PANI/chitosan and the ternary composites shows promising application of the sensor in the detection of acetone vapour at a low concentration down to less than 0.5 ppm. The maximum sensitivity values of about 60 and 180 degree/refractive index change were observed for PANI/chitosan and ternary composite sensing layers, respectively, in comparison with the bare gold-based SPR which shows no response up to 10 ppm concentration of acetone vapour in air. In addition, the two sensing layers show good selectivity to acetone vapour compared to ethanol, methanol, and ammonia. The response in the case of ternary composite shows better linearity with a correlation coefficient of 1.0 compared to PANI/chitosan- and gold-based SPR layers with 0.9999 and 0.9997, respectively.
A Novel Experimental Technique to Simulate Shock Behaviour and Bursting Failure of Roadways
Authors: Wang Gui-feng , Gong Si-yuan , Dou Lin-ming , Li Geng , Cai Wu , Fan Chao-jun
Published: November 2019

Rockburst is a sudden and dynamic failure of rock that can cause serious injury to miners and damage to the underground excavations. Stress path, dynamic disturbance, and support system play important and different roles in the generation processes of rockbursts, resulting rockbursts with variety of reasons and failure modes. A test facility that was capable of simulating such factors was developed to study shock behaviour and bursting failure of roadways. The results demonstrate that the modeled roadway was in good condition and retained a shock resistance capacity after three drop loads. Until the acceleration amplitude increased to a certain level at the time of the fourth dynamic loading, sudden bursting failure of modeled roadway occurred. Many large fragments ejected from the upper and middle regions of the roadway, accompanied with loud noise. A deep pit was observed after the bursting failure. The axial of the fan‐shaped pit had an angle above the vertical. In addition, shock behaviour of the modeled roadway had been changed by the anchor‐net support. Significant differences appeared between the acceleration signals measured in two roadway sections with and without the anchor‐net support. The acceleration magnitude of the supported roadway section was strongly reduced by the presence of the anchor‐net support. Even when the unsupported roadway section underwent a sudden injection failure, the roadway with anchor‐net support was in good condition. This study may eventually lead to a methodology for studying the rockbursting resistance capacity of underground roadways.

Conclusão: O medo de cair é um fator comportamental que apresenta repercussões negativas na mobilidade funcional e risco de quedas do indivíduo com doença de Parkinson, sendo necessário considerar esse fator na elaboração dos protocolos de tratamento do paciente.
Bilateral elastofibroma dorsi - rehabilitation of an uncommon tumor
Authors: Saavedra Mariana Brochado Coelho , Silva André Maia , Pontinha Marco Paulo Rodrigues
Published: November 2019

Elastofibroma are rare, slow-growing, soft tissue benign tumors that originate from mesenchymal tissue. We report an 85-year-old male patient with the diagnosis of bilateral elastofibroma dorsi whose symptoms were bilateral chronic pain in the thoracic spine and limitation of shoulder range of motion. The proposed treatment consisted of a rehabilitation program in our department mainly focused on pain management and postural reeducation of the scapulohumeral rhythm, with great improvements namely on the anterior extension and abduction of the shoulder and with no pain at the 6-month post-treatment reevaluation. This shows an important role of Physical Medicine and Rehabilitation in the management of patients with these rare tumors.

Published: November 2019

Annie Dorsen's digital theatre works reshape the possibilities of the encounter between humans and algorithmic forces. They both address and embody a world in which emotion, cognition, and narrative are increasingly controlled by algorithmic programs; and they invite the spectator to confront a nonhuman and algorithmic logic experientially, altered and pressurized by the terms of the theatre itself.
Inscribing Authority: Scribal and Archival Practices of a Safavid Decree
Authors: Bhalloo Zahir , Rezai Omid
Published: November 2019

The mis̱āl, a type of administrative decree associated with the most important religious official in Safavid Iran (1501-1736), the ṣadr, has received little scholarly attention. This article attempts to lay the preliminary groundwork for a more comprehensive future study on the mis̱āls of the Safavid ṣadrs. In the first part, we introduce the ṣadr and his department, the dīwān al-ṣadāra. In the second part, we study how the scribal and archival practices of the mis̱āl construct the religious and administrative authority of the ṣadr and the dīwān al-ṣadāra. We focus on an unpublished mis̱āl relating to the endowment (waqf) of the shrine of a prominent Sufi shaykh of the Ṭayfūriyya tradition in Basṭām, Shaykh Abū ʿAbdallāh Muḥammad b. ʿAlī Dāstānī (d. 417/1026). The appendix includes the text, translation, and a facsimile of the document.
Chinese and English Horoscopy in the Sixteenth and Seventeenth Centuries: The Astrological Doctrines of the Twelve Houses and the Lot of Fortune in Xingxue dacheng 星學大成 by Wan Minying 萬民英 (1521–1603) and Christian Astrology by William Lilly (1602–1681)
Authors: Kotyk Jeffrey
Published: November 2019

This study compares the astrological doctrines of the Twelve Houses and Lot of Fortune as they are explained in Xingxue dacheng 星學大成 of Wan Minying 萬民英 (1521–1603) and Christian Astrology by William Lilly (1602–1681). These two astrologers, who were near contemporaries, lived on opposite sides of Eurasia, yet both were heir to traditions of astrology that together reached back to identical origins in the Near East. The use of largely similar doctrines between both authors testifies to the enduring integrity of astrology throughout centuries of transmission westward and eastward through multiple cultures and languages.
Is Astrology a Type of Divination? Thomas Aquinas, the Index of Prohibited Books, and the Construction of a Legitimate Astrology in the Middle Ages and the Renaissance
Authors: Rutkin H Darrel
Published: November 2019

What is the relationship between astrology and divination? In particular, is astrology a type of divination, as is often asserted or assumed? In both astrology and divination, knowledge and prediction of the future are primary goals, but does this warrant calling astrology a form of divination? I approach these questions by exploring the response of Thomas Aquinas, which was to be extremely influential for many centuries. First I analyze in some detail Thomas’s answer in his Summa theologiae 2-2.92–95; then I discuss two significant sixteenth-century examples of its influence: the 1557, 1559, 1564, and later indexes of prohibited books; and Pope Sixtus V’s anti-divinatory bull, Coeli et Terrae Creator (1586). In this way, we can explore some of the complex historical dynamics at play in the construction of a legitimate astrology in the Middle Ages and the Renaissance.

Authors: Tyagi Prashant , Ramesh Ch. , Kushvaha S. S. , Gupta Govind , Senthil Kumar M.
Published: November 2019

Evolution of GaN nanostructure grown on Si (111) substrate has been studied systematically using laser molecular beam epitaxial process. The in-situ reflection high energy electron diffraction and ex-situ high resolution X-ray diffraction studies reveal that the GaN nanostructures
have a hexagonal-wurtzite phase and grow along c-axis. The GaN morphology changes from compact granular layer to faceted pyramids to nanowall structure as a function of laser ablation frequency of the KrF excimer laser and radio frequency nitrogen plasma condition. It is observed that
GaN nanowall structure is formed on Si (111) when grown under strong nitrogen-rich flux at a higher growth rate and growth temperature. The crystalline and optical quality of the GaN nanostructures significantly improved with increase of laser ablation frequency. The nanowall structure shows
good optical emission properties with an intense, sharp near-band edge emission and a negligible deep band luminescence.

Published: November 2019

We report the simulation of high-efficiency c-silicon Passivated Emitter Rear Contact (PERC) type solar cell structure with rear side passivated with HfO2 as a passivating material. Variation in the half length of pyramid has been carried out to investigate its effect on
the solar cell electrical characteristics such as fill factor (FF), open circuit voltage (Voc) and efficiency. Aluminum back Surface Field (Al-BSF) and PERC type solar cell with Al2O3 passivation layer structures were also modeled for comparison. Effect
of variation in passivation layer (HfO2) thickness (10 and 15 nm) and permittivity (k = 14 and 25) on the solar cell electrical characteristics has been investigated. Result shows the efficiency improvement in the PERC solar cell with HfO2 passivation layer by
0.5941% and 0.983% as compared to the Al-BSF and PERC with Al2O3 passivation layer at 8 μm pyramid half length. Increased series resistance and reduced FF has been observed with the incorporation of passivation layer at the solar cell structure. Negligible effect
of passivation layer thickness has been observed on the solar cell electrical parameters whereas the permittivity value does have significant effect.

Published: November 2019

This paper reports the attempt to develop an efficient heterostructure photocatalyst by employing SrZrO3 as ferroelectric substrate with deposited nanostructured CdS semiconductor on the surface. Primarily bare SrZrO3 and CdS nanoparticles were synthesized by using
polymeric citrate precursor and co-precipitation routes, respectively. The chemical deposition technique was used to develop the CdS over the surface of the pre-synthesized SrZrO3 nanoparticles. The synthesized bare nanoparticles and their heterostructure were characterized by XRD
which shows the formation of orthorhombic and face centred cubic (FCC) phases of SrZrO3 and CdS, respectively. TEM was used to estimate the morphology and particle size of as-synthesized nanoparticles, which shows the average particle size of 14, 24 and 25 nm for SrZrO3,
CdS and SrZrO3/CdS, respectively. The BET surface area of SrZrO3, CdS and SrZrO3/CdS samples was found to be 299, 304 and 312 m2/g respectively. Methylene blue was used as model pollutant to determine the photocatalytic activity of the synthesized nanomaterials.
The heterostructure shows an enhanced activity as compared to bare nanoparticles. Dielectric constant and dielectric loss of the nanoparticles was investigated as a function of frequency at room temperature and as a function of temperature at 500 kHz. The room temperature dielectric constant
for SrZrO3, CdS and SrZrO3/CdS was found to be 13.2, 17.8 and 25.5 respectively at 100 kHz.

Authors: Killeen Daniel Patrick , Card Asli , Gordon Keith Christopher , Perry Nigel Brian
Published: November 2019

Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are commercially important omega-3 fatty acids found in fish oils. Here we demonstrate that a handheld Raman spectrometer can be used to quantitate these compounds in intact fish oil capsules, avoiding oxidizing risk. Partial least squares regression models were prepared by relating Raman spectral variance to EPA and DHA concentrations determined using gas chromatography–mass spectrometry (GC-MS) analysis of fatty acid methyl esters in 15 commercial samples containing 145–473 mg g−1 EPA and 101–260 mg·g−1 DHA. Handheld Fourier transform (FT)-Raman models had root mean square errors of cross-validation of 38 mg g−1, 24 mg g−1, and 32 mg·g−1 for EPA, DHA, and EPA+DHA, respectively. Models generated from a benchtop FT-Raman spectrometer had corresponding errors of 32 mg·g−1, 22 mg·g−1, and 26 mg·g−1. By comparison, average standard deviations from triplicate GC-MS analyses were 11 mg·g−1 for EPA and 9 mg·g−1 for DHA.
The Usefulness of Spectroscopic Simulations
Authors: Milosevic Milan , Wendland Nils , Lee Robert E. , Gregory Brian W.
Published: November 2019

This article presents a method for extracting the optical constants of homogeneous isotropic materials using the infrared spectra of that material. The method is based on using the harmonic oscillator model of molecular polarizability to obtain optical constants, then calculating the spectrum, comparing the calculated spectrum to an experimental spectrum of the material, and adjusting the model parameters until a close fit between the spectra is obtained. Corrections that need to be made to the experimental spectra in order to remove instrumental distortions are also briefly described. The remainder of the article centers on describing how the optical constants can be used to simulate spectra of that material in different experimental arrangements and the benefits that spectral simulations afford to experimentalists.

Authors: Bogers Marcel , Chesbrough Henry , Heaton Sohvi , Teece David J.
Published: November 2019

Open innovation has become well established as a new imperative for organizing innovation. In line with the increased use in industry, it has also attracted a lot of attention in academia. However, understanding the full benefits and possible limits of open innovation still remains a challenge. We draw on strategic management theory to describe some of these benefits and limits. More specifically, we develop a dynamic capabilities framework as a way to better understand the strategic management of open innovation, which can then help to better explain both success and failure in open innovation. With this background, as guest editors we introduce select papers published in this Special Section of California Management Review that were originally presented at the fifth annual World Open Innovation Conference, held in San Francisco, California, in December of 2018.
Reactive power analysis and frequency control of autonomous wind induction generator using particle swarm optimization and fuzzy logic
Authors: Ezzeddine Touti
Published: November 2019

Wind generation system is becoming increasingly important as renewable energy sources due to its advantages such as low maintenance requirement and mainly it does not cause environmental contamination. This paper presents the improvement procedure of the transient state and the regulation of the output frequency by adjusting the terminal capacitor. The aim is to provide frequency control of a self-excited induction generator in remote site using different strategies which are based on the adjustment of the reactive power at the outputs of a three-phase self-excited induction generator. A thyristor controlled reactor and a switched resistive load will be used to control reactive power. The proposed particle swarm optimization algorithm technique, location of the thyristor controlled reactor device, and parameter value are optimized simultaneously. The results obtained by this strategy will be compared with those provided by the use of Fuzzy Logic Controller. This study will be conducted through the analysis of the frequency in the steady state and transient case using a developed induction generator numerical model built using MATLAB/Simulink. Simulation and experimental results will be exposed and analyzed considering a resistive inductive load on a laboratory test bench.

Published: November 2019

Development of acute type B aortic dissection in an adult patient with untreated coarctation of the aorta is a rare phenomenon. A 62-year-old man was incidentally found to have coarctation of the aorta when he was suffered a type B aortic dissection. Initially, he was treated medically, but the diameter of the proximal descending aorta was progressively expanding. Descending aorta replacement followed by excision of the coarctation and intimal tear were performed electively. Surgical repair resulted in a good outcome.

Published: November 2019

The metabotropic glutamate receptor 5 (mGluR5) is a promising treatment target for psychiatric disorders due to its modulatory effects on glutamate transmission. Using [11C]ABP688, we previously showed that the rapidly acting antidepressant ketamine decreases mGluR5 availability. The mGluR5 radioligand [18F]FPEB offers key advantages over [11C]ABP688; however, its suitability for drug challenge studies is unknown. We evaluated whether [18F]FPEB can be used to capture ketamine-induced effects on mGluR5. Seven healthy subjects participated in three [18F]FPEB scans: a baseline, a same-day post-ketamine, and a 24-h post-ketamine scan. The outcome measure was VT/ fP, obtained using a two-tissue compartment model and a metabolite-corrected arterial input function. Dissociative symptoms, heart rate and blood pressure increased following ketamine infusion. [18F]FPEB VT/ fP decreased by 9% across the cortex after ketamine infusion, with minimal difference between baseline and 24-h scans. Compared to our previous work using [11C]ABP688, the magnitude of the ketamine-induced change in mGluR5 was smaller using [18F]FPEB; however, effect sizes were similar for the same-day post-ketamine vs. baseline scan (Cohen’s d = 0.75 for [18F]FPEB and 0.88 for [11C]ABP688). [18F]FPEB is therefore able to capture some of the effects of ketamine on mGluR5, but [11C]ABP688 appears to be more suitable in drug challenge paradigms designed to probe glutamate transmission.
Content is King: How SMEs Create Content for Social Media Marketing Under Limited Resources
Authors: Kraus Sascha , Gast Johanna , Schleich Moritz , Jones Paul , Ritter Michael
Published: November 2019

Despite the growing literature dealing with social media marketing (SMM) in small and medium-sized enterprises (SMEs), one area that has not been fully explored is the creation of the content itself. SMEs typically do not have the same resources available that larger companies possess. Therefore, they have to find alternative ways to compensate for this weakness. This study analyzes SMEs’ SMM content creation, specifically on Facebook. By first scanning existing literature for essential factors for content creation, a theoretical foundation for the empirical part is presented. A qualitative approach was applied through the use of semi-structured interviews with eight SMEs. The findings suggest that it is difficult for most SMEs to efficiently use available resources, but also that minimal resources are required to create engaging content. Moreover, SMEs are typically aware of the majority of elements that influence content creation, at least to a certain extent, and that they should have established processes and routines to overcome the burden of limited resources. The study concludes with directions for future research and practical recommendations.
The Impact of the Slow City Movement on Place Authenticity, Entrepreneurial Opportunity, and Economic Development
Authors: Çiçek Mesut , Ulu Sevincgul , Uslay Can
Published: November 2019

The Slow City (Cittaslow) concept represents an emerging global trend where participant small cities commit to growing sustainably by preserving their authenticity while celebrating their local culture and diversity. Meanwhile, marketers increasingly find authenticity to be critical for campaigns with efficacy. Using a sample of 762 residents from slow cities, neighboring cities, and other Turkish cities, the authors empirically examine the Slow City movement and demonstrate its positive impact on place authenticity. Slow City membership also positively moderates the effect of perceived authenticity on both perceived entrepreneurial opportunities and economic development, which positively impact quality of life and intention to stay respectively. The results also indicate that the benefits of the Slow City movement spill over to neighboring cities. The Slow City movement offers much promise for place marketing and has potential to slow down the heavy migration from rural to urban areas in emerging markets.

Authors: Bi Yonghua , Li Jindong , Yi Mengfei , Yu Zepeng , Han Xinwei , Ren Jianzhuang
Published: November 2019

Background

Traditional metal stents are not always suitable for patients with circuitous malignant esophageal stricture.

Purpose

We aimed to report the safety and effectiveness of stent insertion using self-expanding segmental radioactive metal stent in the palliation of malignant esophageal stricture.

Material and Methods

We conducted a retrospective analysis of 22 consecutive patients who underwent insertion of segmental radioactive metal stents from November 2016 to March 2019. Technical success, dysphagia score, and complications were analyzed. Kaplan–Meier analysis was used to analyze the survival time.

Results

The stenting procedure was successful in all 22 patients with no procedure-related deaths. Twenty-four segmental radioactive metal stents were successfully implanted. A total of 6 (27.3%) complications were found, mainly 5 (22.7%) stent migrations. The median follow-up period was 3.3 months. Stent removal was required in 4 (12.5%) patients due to complete stent migration. The mean dysphagia score decreased significantly after stent insertion ( P<0.0001). During follow up, 13 patients survived with no obvious clinical symptom and nine patients died. The mean survival was 9.9 months.

Conclusion

The stenting procedure using self-expanding segmental radioactive metal stents is safe and effective in dysphagia palliation of malignant esophageal stricture.
Lasmiditan for the acute treatment of migraine: Subgroup analyses by prior response to triptans
Authors: Knievel Kerry , Buchanan Andrew S , Lombard Louise , Baygani Simin , Raskin Joel , Krege John H , Loo Li Shen , Komori Mika , Tobin Joshua
Published: November 2019

Background

Lasmiditan demonstrated superiority to placebo in the acute treatment of migraine in adults with moderate/severe migraine disability in two similarly designed Phase 3 trials, SAMURAI and SPARTAN. Post-hoc integrated analyses evaluated the efficacy of lasmiditan in patients who reported a good or insufficient response to triptans and in those who were triptan naïve.

Methods

Subgroups of patients reporting an overall response of “good” or “poor/none” to the most recent use of a triptan at baseline (defined as good or insufficient responders, respectively) and a triptan-naïve subpopulation were derived from combined study participants randomized to receive lasmiditan 50 mg (SPARTAN only), 100 mg or 200 mg, or placebo, as the first dose. Outcomes including headache pain-freedom, most bothersome symptom-freedom, and headache pain relief 2 hours post-first dose of lasmiditan were compared with placebo. Treatment-by-subgroup analyses additionally investigated whether therapeutic benefit varied according to prior triptan response (good or insufficient).

Results

Regardless of triptan response, lasmiditan showed higher efficacy than placebo (most comparisons were statistically significant). Treatment-by-subgroup analyses found that the benefit over placebo of lasmiditan did not vary significantly between patients with a good response and those with an insufficient response to triptans. Lasmiditan also showed higher efficacy than placebo in triptan-naïve patients.

Conclusions

Lasmiditan demonstrated comparable efficacy in patients who reported a good or insufficient response to prior triptan use. Lasmiditan also showed efficacy in those who were triptan naïve. Lasmiditan may be a useful therapeutic option for patients with migraine.

Trial Registration

SAMURAI (NCT02439320); SPARTAN (NCT02605174).
Underpaid Boss: Gender, Job Authority, and the Association Between Underreward and Depression
Authors: Schieman Scott , Taylor Catherine J. , Narisada Atsushi , Pudrovska Tetyana
Published: November 2019

Underreward is associated with depression—but is that association contingent upon job authority and other forms of status in the work role? And, do these patterns differ for women and men? Analyses of a national sample of American workers reveal that underreward is more strongly associated with depression among women with higher levels of job authority compared to similarly situated men. The authors then demonstrate that this pattern is amplified when other status elements are considered: income, skill level, autonomy, and decision latitude. These patterns are observed net of a range of sociodemographic measures, work stressors, and workplace sex composition. The findings of this study provide new insights about the gendered ways that job authority and other forms of status shape the association between underreward and depression. In doing so, the authors speak to diverse theoretical traditions related to distributive justice and engage with key ideas of reward expectation states theory. The efforts of the authors dovetail with recent interest in the gendered implications of authority and status as well as their connections to psychological distress.
Carl Milles: Master of Fountains An Interview With Kent Ullberg
Authors: Alt Gordon
Published: November 2019

This past June, I had the opportunity to participate in the National Sculpture Society Annual Meeting in Brookgreen Gardens, and attended a fountain‐side talk on Carl Milles’ Fountain of the Muses. It was given by Swedish/American naturalist and sculptor Kent Ullberg FNSS. After returning to Washington, I decided to revisit Milles’ Fountain of Faith just outside Washington. I realized after seeing these two important fountains, which were Milles’ last two major installations, that it would be an important opportunity to interview Kent on his personal insights and experience with Milles’ work, as well as the influence Milles had on his own growth as a sculptor. It is also an opportunity to reflect how important this giant of fountain design was to public art in this country and how much influence he still has on fountain design.

Published: November 2019

Background

While breastfeeding is considered the optimal method of infant feeding, Canadian breastfeeding rates remain below the World Health Organization recommendations. Breastfeeding self-efficacy is known to positively influence breastfeeding outcomes. While previous research has identified predictors of breastfeeding self-efficacy in the immediate postpartum, this study identified predictors of breastfeeding self-efficacy in the prenatal period. Research aim: The aim of this study was to identify predictors of breastfeeding self-efficacy in the prenatal period among both primiparous and multiparous women.

Methods

A sample of 401 Canadian pregnant women in their third trimester completed an online survey. Stepwise multiple linear regression identified predictors of breastfeeding self-efficacy.

Results

The following variables explained 41.2% of the variance in breastfeeding self-efficacy among the entire sample: feeling prepared for labor and birth, number of children, breastfeeding knowledge, anxiety, length of plan to exclusively breastfeed, income, plan to exclusively breastfeed, and type of health-care provider. Among primiparous women, the following variables explained 31.6% of the variance in breastfeeding self-efficacy: feeling prepared for labor and birth, income, anxiety, length of plan to exclusively breastfeed, education, and marital status. Among the multiparous women, the following variables explained 33.6% of the variance in breastfeeding self-efficacy: anxiety, length of prior exclusive breastfeeding experience, breastfeeding knowledge, and plan to exclusively breastfeed.

Conclusion

Through the identification of predictors of breastfeeding self-efficacy in the prenatal period, health-care providers can strategically target women at risk of low breastfeeding self-efficacy and intervene early to promote breastfeeding.
What is Violence? The Role of Sexism and Social Dominance Orientation in Recognizing Violence Against Women
Authors: Rollero Chiara , Bergagna Elisa , Tartaglia Stefano
Published: November 2019

Violence against women represents a global public health issue of epidemic proportions, as well as a gross violation of women’s human rights. It can take many forms, such as physical aggression, sexual coercion, psychological abuse, and controlling behaviors. The purpose of the study was to extend past research on recognition of violence against women within the framework of the ambivalent sexism theory and the social dominance orientation (SDO) theory. Specifically, we investigated the following: (a) to what extent different behaviors potentially harming women are recognized as a form of violence, and (b) whether gender, SDO, and sexist attitudes influence such recognition. Participants were 264 University students (43.1% males, M age = 23.09 years). They were asked to rate the extent to which several behaviors constituted violence against women. Participants’ sexism was assessed by the short version of the Ambivalent Sexism (ASI) and Ambivalence toward Men Inventory (AMI) scales and the SDO by the SDO Italian scale. Through a factor analysis, we individuated three different groups of behaviors harming women: Physical violence, unequivocally recognized as a form of violence; Limitation of freedom, containing behaviors restraining women’s action; and emotional abuse, encompassing verbally and emotionally aggressive behaviors. We tested the relations between variables through a structural equation model, finding that SDO and sexism had a direct effect on the recognition of violence, whereas the influence of gender was mediated by SDO and sexist attitudes. Thus, not gender per se, but gender-role attitudes that seem to affect recognition of some behaviors as a form of violence against women. Implications are discussed.
Geometrically exact vortex lattice and panel methods in static aeroelasticity of very flexible wing
Authors: Yang Lan , Xie Changchuan , Yang Chao
Published: November 2019

Geometrically exact vortex lattice method and panel method are presented in this paper to deal with aerodynamic load computation for geometrically nonlinear static aeroelastic problems. They are combined with geometrically nonlinear finite element method through surface spline interpolation in the loosely-coupled iteration. From the perspective of theoretical research, both vortex lattice method and panel method are based on the full potential equation and able to model the deflection and twist of the wing, while vortex lattice method is based on the thin airfoil theory, and panel method is suitable for thick wings. Although the potential flow equation is linear, the introduction of geometrically exact boundary conditions makes it significantly different from the linear aeroelastic analysis. The numerical results of a high aspect ratio wing are provided to declare the influence of large deformation on nonlinear static aeroelastic computation compared with linear analysis. Aeroelastic analyses based on geometrically exact vortex lattice method and panel method are also compared with the results of computational fluid dynamics/computational structural dynamics coupling method and the wind tunnel test data. The nonlinear static aeroelastic analysis agrees with the measurement even in considerably large deformation situations.
A new perspective on intergroup conflict: The social psychology of politicized struggles for recognition
Authors: Simon Bernd
Published: November 2019

The article offers a new perspective on intergroup conflict. While building on social psychological foundations laid down in self-categorization theory, it is also critically informed by and incorporates insights from the neighboring disciplines of social, political, and moral philosophy. The new perspective is organized around the principal working hypothesis that many intergroup conflicts, especially those in modern, culturally diverse societies, can be fruitfully understood as politicized struggles for recognition. In addition, four more specific corollary hypotheses are proposed concerning polarization, respected collective identity, embedded dual identity, and tolerance. The new perspective shifts researchers’ attention to the multi-level nature of intergroup conflict and to the novel concepts of recognition and identity as a different equal.

Introduction:

Short stem hip replacements may allow preservation of proximal bone stock and minimise soft tissue disruption, easing future revision surgery. However patient satisfaction with these implants must be determined before widespread use. We aimed to compare patient reported outcome measures (PROMs) between short and conventional stem hip replacements.

Methods:

A systematic review was conducted according to PRISMA guidelines for studies comparing short and conventional stem hip replacements with validated PROMs. Meta-analyses were performed for studies reporting Harris Hip and WOMAC scores. Study bias was assessed with the Cochrane Risk of Bias tool and Newcastle-Ottawa Scale.

Results:

24 studies, incorporating 2593 total hip replacements were included for qualitative analysis. 17 studies were included in the meta-analyses. Of the 7 excluded, 1 study reported the Japanese Orthopaedic Association score and 2 others reported the Oxford Hip score. All three showed no difference between the stems. A meta-analysis of 17 studies reporting Harris hip scores showed no statistically significant difference between short and conventional stems (standard mean difference (SMD) −0.06, 95% CI −0.20—0.07, p = 0.35). 6 studies reported WOMAC scores with higher scores indicating worse outcome. No difference was seen between the two groups (SMD 0.21, 95%CI, −0.01—0.42, p = 0.06). 4 studies reported higher WOMAC scores as better. Once again, a meta-analysis showed no statistically significant difference between the stems (SMD 0.28, 95% CI −0.07—0.63, p = 0.12).

Conclusions:

Our systematic review showed no difference in PROMs between short and conventional stem total hip replacements. This is in keeping with previous evidence but is a more comprehensive analysis. Short stems may have an important role in younger individuals as they allow preservation of proximal femoral bone, minimal access surgery and are amenable to abnormal anatomy. The current literature is hindered by non-uniform methodologies and outcome assessments across studies. Further, standardised, high quality evidence is required before widespread changes in practice.
Setting Up a Cryopreservation Programme for Immature Testicular Tissue: Lessons Learned After More Than 15 Years of Experience
Authors: Braye Aude , Tournaye Herman , Goossens Ellen
Published: November 2019

Young boys undergoing gonadotoxic treatments are at high risk of spermatogonial stem cell (SSC) loss and fertility problems later in life. Stem cell loss can also occur in specific genetic conditions, eg, Klinefelter syndrome (KS). Before puberty, these boys do not yet produce sperm. Hence, they cannot benefit from sperm banking. An emerging alternative is the freezing of testicular tissue aiming to preserve the SSCs for eventual autologous transplantation or in vitro maturation at adult age. Many fertility preservation programmes include cryopreservation of immature testicular tissue, although the restoration procedures are still under development. Until the end of 2018, the Universitair Ziekenhuis Brussel has frozen testicular tissues of 112 patients between 8 months and 18 years of age. Testicular tissue was removed in view of gonadotoxic cancer treatment (35%), gonadotoxic conditioning therapy for bone marrow transplantation (35%) or in boys diagnosed with KS (30%). So far, none of these boys had their testicular tissue transplanted back. This article summarizes our experience with cryopreservation of immature testicular tissue over the past 16 years (2002-2018) and describes the key issues for setting up a cryopreservation programme for immature testicular tissue as a means to safeguard the future fertility of boys at high risk of SSC loss.
Does multilingualism shape personality? An exploratory investigation
Authors: Dewaele Jean-Marc , Botes Elouise
Published: November 2019

Aims and objectives:

Personality psychologists argue that personality is the result of nature and nurture. However, relatively little attention has been paid to the latter. The present study considers the effect of multilingualism, a social factor, on personality.

Methodology:

A total of 651 multilinguals from around the world filled out an online questionnaire containing questions about participants’ language profile and a so-called “Big 5” questionnaire: the Multicultural Personality Questionnaire (short form).

Data and analysis:

Correlation analyses were run between the level of multilingualism of participants and their scores on five personality traits. A parceled structural equation model was then used to examine the influence of multilingualism on three personality subscales.

Findings:

The model indicated significant positive path coefficients between the level of multilingualism and Flexibility, Social Initiative and Open-mindedness.

Significance:

Our findings confirm and expand earlier research that showed that multilingualism/multiculturalism can be considered to be enduring environmental factors that contribute to the shaping of personality profiles.
Thrown into the world: The shift between pavlova and pasta in the ethnic identity of Australians originating from Italy
Authors: Marino Simone
Published: November 2019

Forty-one years on from Huber’s study exploring the assimilation of Italian-Australians, an increasing trend towards ethnic revival can be observed among the third generation of immigrants. Drawing on a case study of a family originating from Calabria in the 1950s and now living in Adelaide, South Australia, I find a widespread intergenerational identification of ethnicity as ‘being Italian’, which has different meanings across the three generations, depending on the individual’s phenomenological perception of being thrown into the world. A pivotal role in this shift of ethnic identity is played by what I refer to as institutional positionality, the individuals’ perceptions of the position of their ethnic ‘being in the world’. By merging sociology of migration, including the Bourdieusian conceptual apparatus of capital, with Heidegger’s existential theory, a reflexive framework is developed that takes into account the relevance of ontology in the field of migration.
