Published: August 2019

AbstractDespite centuries of contact and conquest, Indigenous communities persist in maintaining their cultures and psychologies. Key to this success in cultural survival is the maintenance of Indigenous languages, which contain distinct worldviews. However, Indigenous languages are at risk, with fewer and fewer fluent Elder speakers. Fortunately, there remain committed groups of community educators who carry out Indigenous language education. Current mainstream teacher education programs do not typically introduce the importance of Indigenous language education to teacher candidates, who are the next generation of K‐12 teachers. We view this as highly problematic, and thus carried out a proof‐of‐concept project in which one U.S. university's American Indian/Alaska Native teacher candidates collaborated with, and learned from, Indigenous language educators during a two‐week‐long summer institute at the university. In our article, we share three main findings, based on qualitative analyses of daily‐written student journals collected during the two‐week pilot project: (a) Indigenous language education supports the social justice vision in the American Psychological Association's Multicultural Guidelines; (b) intergenerational educational opportunities are invaluable for affirming Indigenous psychologies; and (c) Indigenous community language educators do important survivance work. Our findings provide insight into how Indigenous language education is crucial for advancing education that honors Indigenous community psychological well‐being.

Published: August 2019

A multifunctional nanomaterial (Fe3O4@SiO2@CX@NH2) comprising a magnetic core, a silicon protective interlayer, and an amphiphilic silica shell is successfully prepared. Ru nanoparticles catalyst loaded on Fe3O4@SiO2@CX@NH2 is used in hydrogenation of α‐pinene for the first time. The novel nanomaterial with amphipathy can be used as a solid foaming agent to increase gas–liquid–solid three‐phase contact and accelerate the reaction. Under the mild conditions (40 °C, 1 MPa H2, 3 h), 99.9% α‐pinene conversion and 98.9% cis‐pinane selectivity are obtained, which is by far the best results reported. Furthermore, the magnetic nanocomposite catalyst can be easily separated by an external magnet and reused nine times with high selectivity maintaining.

ABSTRACTUniaxial and biaxial testing of a three‐dimensional (3D) printed photopolymer (TangoBlackPlus) is performed. The nonlinear material response is studied using specially designed uniaxial and biaxial coupons. Experimental results show a quasi‐isotropic and hyperelastic behavior for longitudinal and transverse directions parallel to the 3D printer build plate. Uniaxial and biaxial testing data are fitted with commonly used hyperelastic material models. The material parameters derived for different material models are implemented into a finite element simulation to illustrate the effect of material models and testing conditions on the deflection of a curved hollow tube undergoing large deformation.HIGHLIGHTS
Advanced three‐dimensional (3D) printing enabled a new sample design for uniaxial and biaxial test coupons.
Uniaxial and biaxial tests were performed for TangoBlackPlus, a new photopolymer commonly used in 3D printing.
Uniaxial and biaxial testing demonstrated an isotropic and hyperelastic material behavior for the different coupons' orientations studied.
Biaxial testing enables a unique identification of the Mooney–Rivlin coefficients due to a large number of deformation states.
Material coefficients were derived for different models and used as input parameters for finite element modeling. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2020, 137, 48400.

AbstractProducing polyester monomer 2,5‐furandicarboxylic acid (FDCA) from biomass as an alternative to fossil‐derived terephthalic acid has drawn much attention from both academy and industry. In this work, an efficient FDCA synthesis was proposed from 10.6 wt % 2,5‐diformylfuran (DFF) in acetic acid using a combined catalytic system of Co/Mn acetate and N‐hydroxyimides. The intermediate product of 5‐formyl‐2‐furandicarboxylic acid (FFCA) possesses the least reactive formyl group. N‐hydroxysuccinimide was found to be superior to N‐hydroxyphthalimide in catalyzing the oxidation of the formyl group in FFCA intermediate, affording a near 95 % yield of FDCA under mild conditions of 100 °C. Trace maleic anhydride was detected as by‐product, which mainly came from the oxidative cleavage of DFF via furfural, furoic acid and 5‐acetoxyl‐2(5H)‐furanone as intermediates.

Published: August 2019

AbstractMercury ion (Hg2+) is a universal pollutant and its detection is crucial for public healthcare. In this study, we developed a novel fluorescent biosensor by construction of a protein fusion between the mercury‐sensing transcription factor MerR and enhanced yellow fluorescent protein (EYFP). Hg2+‐induced conformational change of MerR was transduced into fluorescence signal. Fluorescence intensity of the biosensor protein decreased with increasing concentrations of Hg2+ and a linear response was obtained in the range of 0.5–40 nM. The limit of detection was 0.5 nM, which was much lower than the maximum allowed level in water. The biosensor specificity was highly dependent on type and concentration of metal ion. The biosensor exhibited high specificity in a mixture of metal ions at 0.5 nM concentration. However, the interference effect was more pronounced at 40 nM concentration of metal ions. The measurement was completed in less than 1 Min with no need for sample preparation or preincubation steps. The biosensor achieved accurate and reliable detection in the spiked drinking water sample, as validated by the inductively coupled plasma optical emission spectrometry.
An improved solution for deformation simulation of nonorthotropic geometric models

Published: August 2019

AbstractPhysically based deformation simulation has been studied for many years in computer graphics. In order to simulate more complex geometric models and better meet the designer's requirements, many anisotropic approaches have been proposed in recent years. However, most of the approaches focus on simulating orthotropic models. In comparison with orthotropic models, nonorthotropic ones allow the objects to have anisotropic behaviors along nonorthogonal directions. In this paper, we introduce an improved approach to simulate nonorthotropic geometric models under large deformation. The improvements are mainly twofold. First, a frame field is specified on a given undeformed object, that is, each point of the object is equipped with a frame. In each local frame, we construct three independent vectors and form a nonorthogonal coordinate. Second, we design the deformation properties along each axis in the local nonorthogonal coordinate to get a local constitutive model. The final nonorthotropic model is generated by transforming the designed model from local nonorthogonal coordinates to the global standard Cartesian coordinate. To improve the stability, we introduce a time‐varying method to simultaneously track the local coordinates reorientation by pushing forward the original frame field to the deformed frame field. Experiments show that the deformation simulation using the designed nonorthotropic models exhibits anisotropic behaviors along different directions and are more stable than previous methods.

Published: August 2019

AbstractIn the present work, we investigate the efficiency of TiO2 photoelectrode layers on boron‐doped diamond foil (BDDF) in comparison with a classic conducting glass (fluorine‐doped tin oxide, FTO) back contact. Crystalline thin TiO2 layers were prepared on the substrates by two different methods: (i) deposition of metallic Ti thin films followed by thermal oxidation to form TiO2 (TO‐TiO2), (ii) reactive sputter deposition of TiO2 thin films and crystallization of these layers (SP‐TiO2). The optimized layers show that TO‐TiO2 films on BDDF deliver a significantly higher incident photon to current efficiency (IPCE) compared to directly sputtered SP‐TiO2 layers and these layers on BDDF also outperform FTO as a back contact. We ascribe this beneficial effect of the BDDF back contact to the formation of an intermediate conductive phase of Ti carbides at the TO‐TiO2/BDDF interface.

AbstractThe relationship between the photophysical properties and molecular orientation of 1,3,6,8‐tetraalkylpyrenes in the solid state is described herein. The introduction of alkyl groups with different chain structures (in terms of length and branching) did not affect the photophysical properties in solution, but significantly shifted the emission wavelengths and fluorescence quantum yields in the solid state for some samples. Pyrenes bearing ethyl, isobutyl, or neopentyl groups at the 1‐, 3‐, 6‐, and 8‐positions showed similar emission profiles in both the solution and solid states. In contrast, pyrenes bearing other alkyl groups exhibited an excimer emission in the solid state, similar to that of the parent pyrene. On studying the photophysical properties in the solid state with respect to the obtained crystal structures, the observed solid‐state photophysical properties were found to depend on the relative position of the pyrene chromophores. The solid‐state photophysical properties can be controlled by the alkyl groups, which provide changing crystal packing. Among the pyrenes tested, 1,3,6,8‐tetraethylpyrene showed the highest fluorescence quantum yield of 0.88 in the solid state.

Published: August 2019

AbstractMulticomponent Mannich reactions through C−H bond activation are described. These transformations allowed for the straightforward generation of densely substituted benzylic and homo‐benzylic amines in good yields. The reaction involves a reaction between two transient species: an organometallic species, generated by transition‐metal‐catalyzed sp2 or sp3 C−H bond activation and an in situ generated imine. The use of an acetal as an aldehyde surrogate was found essential for the reaction to proceed. The process could be successfully applied to RhIII‐catalyzed sp2 C−H bond functionalization and extended to CuII‐catalyzed sp3 C−H bond functionalization.
Power, CSR strategy, and performance in foreign‐owned subsidiaries
Authors: Dahms Sven 
Published: August 2019

AbstractWe investigate how a subsidiary's power base influences its strategic corporate social responsibility (CSR) focus on international and local issues, and performance. We develop a theoretical framework and test symmetric hypotheses as well as non‐symmetric research queries based on insights from resource dependency theory and institutional theory. We use survey data collected from foreign‐owned subsidiaries located in the mid‐range emerging economy of Taiwan. We find that a large power base positively influences an international CSR strategic focus in subsidiaries. Furthermore, our symmetric results indicated that only international CSR strategies are conducive to performance. However, our complementing non‐symmetric results show that the distinct power‐base dimensions in combination with a local CSR strategic focus can also lead to high performance outcomes.

Published: August 2019

AbstractA newly developed bio‐reactor design for municipal sewage treatment was evaluated on a pilot scale (150 m3/d). The reactor system included both anaerobic/anoxic and aerobic treatment stages with external/internal airlift circulation loops integrated with a central sedimentation chamber. The design was conceived to enhance the removal of organic compounds and nutrients (phosphorus and nitrogen) within a smaller footprint than existing treatment processes. The downcomer of the internal circulation loop is integrated with the sedimentation tank facilitating high efficiency solid‐liquid separation in a compact configuration. The external/internal airlift circulation stages increase the potential for bio‐reactivity, while reducing energy consumption for process flows. Overall, the integrated configuration reduces the footprint required compared to conventional systems with equivalent hydraulic loads, ie, hydraulic retention time of ~12.8 hours with a hydraulic loading area of 10.3 m3/d/m2. The trial run data indicated removal efficiencies for COD, phosphorous, ammonia, and total nitrogen of 94.5%, 94.5%, 96.8%, and 78.6% respectively. Moreover, the treatment system also demonstrated a robust capacity to handle a wide range of COD influent concentrations (ie, ~ 120‐860 mg/L).

BackgroundA critical knowledge gap exists regarding the impact of neurologic deficits on surgical outcomes and health‐related quality of life (HRQOL) for patients surgically treated for metastatic epidural spinal cord compression (MESCC).MethodsThis prospective, multicenter and international study analyzed the impact of the neurologic status on functional status, HRQOL, and postoperative survival. The collected data included the patient demographics, overall survival, American Spinal Injury Association (ASIA) impairment scale, Spinal Instability Neoplastic Score, treatment details and complications and HRQOL measures, including version 2 of the 36‐Item Short Form Health Survey (SF‐36v2) and version 2.0 of the Spine Oncology Study Group Outcomes Questionnaire (SOSGOQ2.0).ResultsA total of 239 patients surgically treated for spinal metastases were included. Six weeks after treatment, 99 of the 108 patients with a preoperative ASIA grade of E remained stable, 8 deteriorated to ASIA D, and 1 deteriorated to ASIA A. Of 55 patients with ASIA D, 27 improved to ASIA E, 27 remained stable and 1 deteriorated to ASIA C. Of 11 patients with ASIA A to C, 2 improved to ASIA E, 4 improved to ASIA D, and 5 remained stable. At the 6‐ and 12‐week follow‐up, better ASIA scores were associated with better scores on multiple SF‐36v2 and SOSGOQ items. Postoperatively, patients with ASIA grades of A to D were more likely to have urinary tract infections and wound complications. Patients with a baseline ASIA grade of E or D survived significantly longer.ConclusionsPatients with neurologic deficits due to MESCC have worse HRQOL and decreased overall survival. Nevertheless, surgery can result in stabilization or improvement of neurologic function which may translate into better HRQOL. Postoperative care and follow‐up are challenging for patients with neurologic deficits because they experience more complications.

BackgroundHuman papillomavirus (HPV) infection is the central factor for cervical cancer, whereas epithelial immune mechanisms contribute to the progression of HPV infection and its associated lesions. The authors evaluated the expression of indoleamine 2,3‐dioxygenase (IDO) and tryptophan 2,3‐dioxygenase (TDO) in cervicovaginal samples from women with normal cervical epithelium or with different degrees of squamous intraepithelial lesions (SILs) and cervical cancer.MethodsIDO expression was analyzed by immunocytochemistry in liquid‐based cytology samples from 165 women, of whom 42 had cervical changes subclassified as low‐grade SIL (n = 6), high‐grade SIL (n = 30), or squamous cell carcinoma (SCC) (n = 6), and 123 had negative Papanicolaou smears. IDO and TDO expression also were analyzed by immunohistochemistry, and HPV and other genital pathogens were evaluated by polymerase chain reaction analysis.ResultsLow IDO expression was observed in normal cervical epithelium irrespective of HPV status. Increased numbers of IDO‐positive squamous cells and IDO‐positive leukocytes were observed in women with SIL or SCC. TDO expression was detected in leukocytes infiltrating the stroma around intraepithelial or invasive cervical lesions. Higher IDO levels were detected in organotypic epithelial cultures established from keratinocytes transduced with the HPV16 E6/E7 oncoproteins.ConclusionsThe upregulation of IDO expression in leukocytes and squamous cells in HPV‐associated SIL and SCC suggests that immunosuppressive mechanisms involving tryptophan metabolism may have a role in cervical carcinogenesis. Although previous studies have suggested the role of IDO in HPV pathogenesis, this is the first evidence of TDO involvement in the process. Furthermore, the current data emphasize the role of leukocytes, especially neutrophil‐like cells, as an IDO source.

Exploring identity and personal meanings in psychosis using the repertory grid technique: A systematic review
Authors: García‐Mieres Helena , Niño‐Robles Noelia , Ochoa Susana , Feixas Guillem 
Published: August 2019

AbstractCurrent research and clinical practice in person‐centred approaches highlight the importance of self, identity, and personal meanings in psychosis. Previous research has focused on dimensions of self, but less attention has been paid to the personal meanings involved in identity. The personal construct theory framework and the repertory grid technique (RGT) allow the study of identity and personal meanings within person‐centred approaches of psychopathology and treatment in psychosis, as suggested by studies that began more than 40 years ago. However, their contributions have not yet been reviewed. We aimed to systematically review the evidence for the role of identity and personal meanings in psychotic disorders. We performed a systematic search using personal construct and RGT terms in PsycINFO, Web of Science, PubMed, EBSCO, Scopus, and Google Scholar. After identifying 2,574 articles, 15 were included. Nine studies followed an idiographic assessment, and six were nomothetic. Patients reported their subjective experience of isolation in terms of high self‐ideal discrepancy and high perceived discrepancy with their significant others, which some studies associated with a lower degree of recovery or with the way in which positive symptoms were construed. Self‐fragmentation either decreased with interventions or was associated with recovery. Evidence regarding interpersonal construing was less consistent, but there was a tendency for patients to show a more rigid cognitive structure than controls. To conclude, we found some evidence that self‐discrepancies, fragmentation of self, and interpersonal construing are affected in psychosis and potentially modifiable through psychotherapy.

Published: August 2019

AbstractCrystal facet engineering of semiconductor photocatalysts is regarded as an emerging strategy to tune their physicochemical properties and optimize the photoreactivity of the materials. In this work, two plate‐like Bi2MoO6 samples were prepared, dominant in either the distinctly different {100} or {010} facets. As a consequence of the electronic structure effects induced by the facets, the {100}‐dominant Bi2MoO6 (100‐BMO) possessed a smaller band gap and delivered a much higher photocatalytic water oxidation activity than {010}‐dominant Bi2MoO6 (010‐BMO). A greater charge carrier density in 100‐BMO was found to promote electron accumulation on the {100} surfaces, leading to the narrower band gap, as supported by Mott‐Schottky measurements. Efficient intrinsic electron‐hole separation and longer charge carrier lifetimes in 100‐BMO were also observed. Further, a higher photocurrent density and smaller Nyquist plot arc radius presented by 100‐BMO imply a higher charge transfer capacity. EPR analysis indicated that the 100‐BMO boasted a higher oxygen vacancy density, whereby the vacancies could serve as shallow donors to trap electrons and suppress photogenerated electron‐hole pair recombination. Overall, the {100} facet in Bi2MoO6 delivered a mix of distinctly advantageous characteristics relative to the {010} facet with the findings clearly illustrating the value of crystal facet engineering in boosting photocatalytic performance.
