Polychromatic electrochromic films via bipolar covalent organic framework design

Because of the ordered and loose structure, covalent organic framework (COF) holds broad promise in the field of electrochromism, but the simple color change limits its application and development. A bipolar and polychromatic COF-GZU1 was successfully designed and prepared in this paper. The structure, electrostatic potential and orbital structure of the COF-GZU1 were predicted and calculated using density functional theory, and the calculation results confirmed the feasibility of bipolar construction strategy. XRD, SEM, BET and GIWAXS further mutually established the successful synthesis of COF-GZU1, which exhibited high specific surface area, crystallinity and porosity. Results from electrochemical impedance spectroscopy, density of states analysis, and ion diffusion coefficient measurements verified that the ordered porous structure facilitates electron conduction and ion mass transfer, leading to a significant improvement in electrochromic performance. Moreover, the COF-GZU1 film displayed excellent electrochromic performance, providing polychromatic switching with a rapid response time (7.8/14.5 s and 1.0/12.6 s for coloring/bleaching process) and high coloring efficiency (112.8 and 127.8 cm2∙C-1 at 799 and 570 nm). These results collectively demonstrate the superiority of the COF-GZU1 film and suggest that the bipolar COF design strategy could pave the way for new and high-performance polychromatic electrochromic materials.

The influence of a business game on the formation of the internal lexical-semantic context of a speech act: an empirical study

Introduction. Modern tendencies in education require the training of specialists for the labour market, taking into account the changing requirements and influence of the environment. The influence of sociocultural contexts is reflected in the system of human relations with the world, manifested in actions and motives, represented in the speech act. The individual internal lexical and semantic context of a speech act is deterministic by subjective predictors (type of communication, meaningful roles, consistency of the Self-real/Self-ideal, rigidly bound constructs). The article was aimed to show how the business game of the contextual type influences the formation of the individual internal lexical and semantic context of each student of the experimental group. Materials and Methods. The study covered two academic years and involved students (N=39) studying in the academic year 2021/22 in the 1st year and in the academic year 2022/23 in the 2nd year). A contextual type business game was developed for the study. The technique of repertoire lattices of J. Kelly, Cotherapeutic computer system «Kelly», methods of mathematical statistics (χ2 -Pearson for identifying the degree of consistency of nominative features - type of communication, consistency of I-real and I-ideal on the basis of role preferences) were used. Measurements were taken before and after the business game. The results were processed using the computer program «Statistica» (vers. 12). Results and discussion. It was revealed that the contextual type business game influenced the subjective predictors of individual internal lexical-semantic context of each student's speech act. Obtained on the basis of the technique of repertoire grids, personal bipolar constructs, processed in the computer system «KELLY», allowed to identify the role preferences and consistency of the real self and the ideal self, the type of communication, and individual rigidly connected constructs. Mathematical and static analysis revealed a statistically significant shift in the change in the type of communication (χ2 = 6.838; p < 0,05) before and after the business game. Conclusion. The experiment showed that a contextual business game creates conditions for the formation and development of communicative, conflict-related, sociocultural competencies.

Criminal thinking as a bipolar dimensional construct: Testing the risk-promotive status of the PICTS proactive and reactive criminal thinking scales.

This study sought to assess whether two scales from a criminal thinking inventory displayed bipolar properties such that high scores on these scales reflect a risk effect and low scores a promotive effect. To test this hypothesis, the proactive criminal thinking (PCT) and reactive criminal thinking (RCT) scales from the Psychological Inventory of Criminal Thinking Styles (PICTS) were organized into three categories-top 25% of scores (high group), the middle 50% of scores (intermediate group), and bottom 25% of scores (low group)-and crossed with preincarceration (prior convictions and age at first conviction), peri-incarceration (total and aggressive institutional infractions), and postincarceration (revocation and rearrest) outcome indicators. Participants for this study were 3,039 male inmates who completed the PICTS while confined in a medium-security federal prison. Results showed that the PCT and RCT each achieved a mixed (risk and promotive) effect for four out of six outcomes. Of the four unipolar effects, PCT achieved a promotive effect but not a risk effect for the two preincarceration outcomes, whereas RCT produced a risk but not promotive effect for the two postincarceration outcomes. These results provide support for the notion that PCT and RCT are primarily bipolar dimensional constructs in which high scores are associated with negative criminal justice outcomes and low scores with positive criminal justice outcomes, although there may be unipolar aspects to each scale as well.

Unravelling early childhood pre-service teachers’ implicit stereotypes of scientists by using the repertory grid technique

Considering teachers’ roles in developing children’s scientific literacy in preschools, a better understanding of pre-service teachers’ conceptualizations about scientific inquiry and scientists’ practices that have an impact on the science teaching practices offered to their future students is very much needed. Stereotypes were examined here as a component or root for many of the explanations for pre-service teachers’ conceptualizations about scientists. Aligned with the interpretivist paradigm, this phenomenographic study was, mostly qualitative in nature, specifically concerned with exploring pre-service teachers’ stereotypes of scientists by using the repertory grid technique, in which they perceived and differentiated between scientists. 119 early childhood pre-service teachers were recruited. Various types of analysis were carried out to analyze the data gathered in each repertory grid. We investigated the original 66 elicited bipolar constructs into 28 aggregated bi-polar construct groupings, systematically categorized into four bi-polar categories: (1) Recognition vs. Disregarded, (2) Scientific Integrity vs. Misconduct, (3) Communal vs. Dissociation, and (4) Agentic vs. Passivity. The findings suggest that pre-service teachers had typical stereotypical traits of scientists like being introverted, intelligent loners, into experiments and masters in their field with often-unrecognizable female figures. However, there was no association between gender, grade, and stereotypes of scientists elicited in the study. These types of stereotypes of scientists might potentially threaten effective science teaching at early ages. Science education practices can be rooted in these stereotypes of pre-service teachers. Considering these findings, structural changes in science education practices in teacher education programs are very much needed. This study also seems to confirm the importance of using the repertory grid technique as a good starting point to expose especially the implicit stereotypes of pre-service teachers about “who does science”, “how scientists think” and “what scientists do” before their actual actions in future classrooms.

Bipolar Fusionless Versus Standard Fusion Surgery in Neuromuscular Scoliosis: A Two-center Comparative Study.

Nonrandomized controlled cohort. To compare early results between bipolar fusionless construct (BFC) and single posterior fusion (SPF) surgery in neuromuscular scoliosis (NMS). Surgical treatments for NMS have traditionally been characterized by high complication rates. A mini-invasive BFC was developed to reduce these risks while maintaining adequate curve reduction. There is, however, a current lack of studies comparing clinical and radiologic perioperative outcomes between both techniques. All patients surgically treated for NMS with to-pelvis construct between 2011 and 2021 at 2 centers were included and divided into 2 groups according to the surgical technique (BFC or SPF). Gender, age, main deformity region, etiology, preoperative and postoperative main curve magnitude and pelvic obliquity, surgery time, estimated blood loss and transfusion rates, length of hospital stay, the magnitude of main curve and pelvic obliquity correction, and early complications were compared. Quantitative data were compared through ANOVA or Mann-Whitney test. Analysis of qualitative outcomes was performed through Fisher exact test and logistic regressions. Kruskal-Wallis test was used to compare complications between groups. Eighty-nine NMS patients were included: 48 in the SPF group and 41 in the BFC group. Surgery time (203 vs. 241min), rate (32 vs. 52%) and severity of complications, unplanned returns to the operating room (15 vs. 39%), estimated blood loss (179 vs. 364 cc), and transfusion rates (27 vs. 73%) were lower in the BFC group ( P <0.05). There were no significant differences in age, maturity stage, preoperative curve magnitude, preoperative pelvic obliquity and postoperative curve, and pelvic obliquity correction between groups. BFC may be a safer and less invasive option for NMS surgical treatment, resulting in similar curve corrections while significantly decreasing the number and severity of complications as well as intraoperative blood loss when compared with SPF. Level -lll.

Conflicting perspectives on urban landscape quality in six urban regions in Europe and their implications for urban transitions

The European Landscape Convention urges countries to involve stakeholders including citizens in the governance of ordinary (urban) landscapes. This paper studies conflicting stakeholder perspectives on urban landscape quality in the context of urban sustainability transitions in six European urban regions in the Netherlands, Italy, France, Croatia, Belarus and the Russian Federation. Repertory grid technique helped to identify the dimensions through which persons evaluate urban landscape quality. Ninety-three (93) interviewees elicited 1400 bipolar constructs, such as “Edible green – Concrete” or “Community, group – Loneliness”. They then selected two constructs they consider most relevant in the context of urban sustainability transitions, and ranked all pictures on a 10-points scale. The rankings were analyzed using Multiple Correspondence Analysis. We find that, in spite of the many social and cultural differences between the regions, stakeholders largely agree on the preferred direction of urban transitions; more green and blue spots where people can meet and undertake joint (leisure) activities. The main conflict is between, on the one hand, a preference for organized development and beautification and, on the other hand, naturalness (permeability of soil) and organic development. The paper considers several challenges for transition governance.

What makes people happy? Decoupling the experiential‐material continuum

AbstractExtant literature suggests that consumers derive more happiness from experiences (e.g., vacations) than from material possessions (e.g., furniture). However, this literature typically pits material against experiential consumption, treating them as a single bipolar construct of their relative dominance: more material or more experiential. This focus on relative dominance leaves unanswered questions regarding how different levels of material and experiential qualities each contribute to happiness. Four preregistered studies (N = 3,288), using hundreds of product categories, measured levels of material and experiential qualities using two unipolar items. These studies investigate recalled, evoked, and anticipated happiness. Results show a more nuanced view of the experiential advantage that is critical for future research and consumer theory: material and experiential qualities both have positive relationships with happiness. Further, there is no inherent trade‐off between experiential and material qualities: consumers can enjoy consumption that is high on both (e.g., swimming pools and home improvements).

Electrochemically Mediated Direct CO2 Capture by a Stackable Bipolar Cell.

The unprecedented increase in atmospheric CO2 concentration calls for effective carbon capture technologies. With distributed sources contributing to about half of the overall emission, CO2 capture from the atmosphere [direct air capture, (DAC)] is more relevant than ever. Herein, an electrochemically mediated DAC system is reported which utilizes affinity of redox‐active quinone moieties towards CO2 molecules, and unlike incumbent chemisorption technologies which require temperature or pH swing, relies solely on the electrochemical voltage for CO2 capture and release. The design and operation of a DAC system is demonstrated with stackable bipolar cells using quinone chemistry. Specifically, poly(vinylanthraquinone) (PVAQ) negative electrode undergoes a two‐electron reduction reaction and reversibly complexes with CO2, leading to CO2 sequestration from the feed stream. The subsequent PVAQ oxidation, conversely, results in release of CO2. The performance of both small‐ and meso‐scale cells for DAC are evaluated with feed CO2 concentrations as low as 400 ppm (0.04 %), and energy consumption is demonstrated as low as 113 kJ per mole of CO2 captured. Notably, the bipolar cell construct is modular and expandable, equally suitable for small and large plants. Moving forward, this work presents a viable and highly customizable electrochemical method for DAC.

From in vitro evaluation of a finite element model of the spine to in silico comparison of spine instrumentations

Growth-preserving spinal surgery suffer from high complications rate. A recent bipolar instrumentation using two anchoring points (thoracic and pelvic) showed lower rates, but its biomechanical behaviour has not been characterised yet. The aim of this work was to combine in vitro and in vivo data to improve and validate a finite element model (FEM) of the spine, and to apply it to compare bipolar and classical all-screws implants.Spinal segments were tested in vitro to measure range of motion (ROM). Thoracic segments were also tested with bipolar instrumentation to measure ROM and rod strain using a strain gage.A subject-specific FEM of the spine, pelvis and ribcage of an in vivo asymptomatic subject was built. Spinal segments were extracted from it to reproduce the in-vitro mechanical tests. Experimental and simulated ROM and rod strain were compared. Then, the full trunk FEM was used to compare bipolar and all-screws instrumentations.The FEM fell within 1° of the experimental corridors, and both in silico and in vitro instrumentation rods showed 0.01% maximal axial strain. Bipolar and all-screws constructs had similar maximal Von Mises stresses.This work represents a first step towards subject-specific simulation to evaluate spinal constructs for neuromuscular scoliosis in children.

Digital Political Participation of Western and Eastern Parts of Germany Residents (based on Change.org Online Petitions)

The article shows the results of a study aimed at finding the determinants, which describe the petitioning activity of the residents of the western and eastern parts of Germany. The research material consists of 1,036 petitions from the German-language segment of Change.org during the period of 2012–2018 (322 petitions from eastern part of Germany, 714 petitions from western part of Germany). A thematic classifier based on the analysis of electronic petitions was created. It subdivided all the petitions into 18 thematic groups, for example, human rights, animal protection, culture, politics, migration issues, proposals for reforming certain areas of life, transport system, Internet, protection and support for people with disabilities and rare diseases, financial questions, environmental protection, housing issues, weapons/spirits/tobacco/drugs, healthcare, elderly people, education, sports, sustainable development. Statistically significant differences between western and eastern territories were found only in the animal protection thematic group. It is stated that the bipolar construct East/West rooted in the historical logic of the legacy of socialism and capitalism on the German territories could not explain the logic of the petitioning activity of the contemporary Germans. Moreover, the historical heritage/separation factor is found in the socio-economic problems of the regions, but it is not critical while determining the values and civic activism of German people.

Optimism versus pessimism as predictors of physical health: A comprehensive reanalysis of dispositional optimism research.

Prior research has related dispositional optimism to physical health. Traditionally, dispositional optimism is treated as a bipolar construct, anchored at one end by optimism and the other by pessimism. Optimism and pessimism, however, may not be diametrically opposed, but rather may reflect 2 independent, but related dimensions. This article reports a reanalysis of data from previously published studies on dispositional optimism. The reanalysis was designed to evaluate whether the presence of optimism or the absence of pessimism predicted positive physical health more strongly. Relevant literatures were screened for studies relating dispositional optimism to physical health. Authors of relevant studies were asked to join a consortium, the purpose of which was to reanalyze previously published data sets separating optimism and pessimism into distinguishable components. Ultimately, data were received from 61 separate samples (N = 221,133). Meta-analytic analysis of data in which optimism and pessimism were combined into an overall index (the typical procedure) revealed a significant positive association with an aggregated measure of physical health outcomes (r = .026, p < .001), as did meta-analytic analyses with the absence of pessimism (r = .029, p < .001) and the presence of optimism (r = .011, p < .018) separately. The effect size for pessimism was significantly larger than the effect size for optimism (Z = -2.403, p < .02). Thus, the absence of pessimism was more strongly related to positive health outcomes than was the presence of optimism. Implications of the findings for future research and clinical interventions are discussed. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

“Extreme emotions” - the impact of reproductive life events for women living with bipolar disorder

Little is known about how women with bipolar disorder construct and experience reproductive life events across the lifespan. We analyzed qualitative data from 29 semi-structured interviews with women aged 22-63 years (reproductive, menopause and post-menopause phases) using thematic analysis through a social constructionist framework. Themes of “Losing a sense of self-agency and self-worth” contained accounts of feeling out of control because of both bipolar disorder and reproductive life events. “Building a sense of personal autonomy and positive self-image” included accounts of acceptance and management of mood change over time, particularly for women in menopause and post-menopause life phases.

One-Way Self-Expanding Rod in Neuromuscular Scoliosis

Background:Fusionless techniques for the treatment of neuromuscular early-onset scoliosis (EOS) are increasingly used to preserve spinal and thoracic growth and to postpone posterior spinal fusion (PSF). These techniques have greatly improved thanks to magnetically controlled growing rods, which allow the avoidance of repeated surgery. However, the surgery-related complication rate remains high. The objective of the current study was to report the preliminary outcomes of 21 patients with neuromuscular EOS who were treated with a 1-way self-expanding rod (OWSER). This device was designed to avoid repeated surgery and preserve spinal and thoracic growth thanks to its free rod sliding.Methods:Patients with neuromuscular EOS who underwent OWSER fixation were prospectively reviewed; follow-up was a minimum of 3 years. The instrumentation relies on a bipolar construct from T1 to the sacrum, with proximal fixation by double thoracic hook-claws and distal fixation by iliosacral screws. The device comprises a rod with a notched part sliding in 1 direction inside a domino. Changes in Cobb angle, pelvic obliquity, thoracic kyphosis, lumbar lordosis, T1-S1 and T1-T12 length, space available for the lung, and chest width were assessed. Complications were reviewed.Results:The mean age at surgery was 10.5 years. The mean follow-up was 3.9 years. The mean pelvic obliquity improved from 20° preoperatively to 8° postoperatively and to 6° at the latest follow-up. The mean Cobb angle improved from 66° preoperatively to 38° postoperatively and to 32° at the latest follow-up. The mean preoperative kyphosis was reduced from 41° to 26° at the latest follow-up (p = 0.14). The mean lordosis was 34° preoperatively and 38° at the latest follow-up. The mean growth per month was 0.8 mm for the T1-T12 segment and 1.5 mm for T1-S1. The global complication rate was 38% (2 surgical site infections, 3 cases of lack of rod expansion, 1 case of pyelonephritis, and 2 central venous catheter-related infections). No PSF had been performed at the latest follow-up.Conclusions:Use of the OWSER with a minimally invasive bipolar technique for neuromuscular EOS provided satisfactory correction of spinal and pelvic deformities at 3 years of follow-up. A longer follow-up is required.Level of Evidence:Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

High-Ni ternary perovskite fluorides KNCMF-811 mediated with bipolar redox electrolytes construct advanced supercapacitors in both alkaline and neutral media.

Biomechanical cadaver study of proximal fixation in a minimally invasive bipolar construct.

Biomechanical human cadaver study. To determine the three-dimensional intervertebral ranges of motion (ROMs) of intact and hook-instrumented thoracic spine specimens subjected to physiological loads, using an in vitro experimental protocol with EOS biplane radiography. Pedicle screws are commonly used in thoracic instrumentation constructs, and their biomechanical properties have been widely studied. Promising clinical results have been reported using a T1-T5 thoracic hook-claw construct for proximal rod anchoring. Instrumentation stability is a crucial factor in minimizing mechanical complications rates but had not been assessed for this construct in a biomechanical study. Six fresh-frozen human cadaver C6-T7 thoracic spines were studied. The first thoracic vertebrae were instrumented using two claws of supra-laminar and pedicle hooks, each fixed on two adjacent vertebrae, on either side of a single free vertebra. Quasi-static pure-moment loads up to 5Nm were applied to each specimen before and after instrumentation, in flexion-extension, right and left bending, and axial rotation. Five steel beads impacted in each vertebra allowed 3D tracking of vertebral movements on EOS biplanar radiographs acquired after each loading step. The relative ranges of motion (ROMs) of each pair of vertebras were computed. Mean ROMs with the intact specimens were 17° in flexion-extension, 27.9° in lateral bending, and 29.5° in axial rotation. Corresponding values with the instrumented specimens were 0.9°, 2.6°, and 7.3°, respectively. Instrumentation significantly (P < 0.05) decreased flexion-extension (by 92-98%), lateral bending (by 87-96%), and axial rotation (by 68-84%). This study establishes the biomechanical stability of a double claw-hook construct in the upper thoracic spine, which may well explain the low mechanical complication rate in previous clinical studies. Not applicable, experimental cadaver study.

Implicitna uverenja nastavnika o (matematičkoj) inteligenciji

Implicit theories of intelligence are individual beliefs about the nature of intelligence, which are used on a daily basis as part of self-assessment and assessment of others, and are a significant factor shaping attitudes and behaviors. Research to date suggests that teachers can influence their students' beliefs about intelligence, which in turn affect motivation and achievement. According to Dweck's model, implicit theories of intelligence are a bipolar construct, with two theories at its extremes - the entity theory, which stresses the immutability of intelligence, and the incremental theory, which holds that intelligence can be improved through training and learning. Recent research, however, indicates that these two theories represent distinct, uncorrelated dimensions. The aim of this study was to carry out a psychometric evaluation of the Implicit Theories of Intelligence Scale (ITIS) and the Mathematics-Oriented Implicit Theory of Intelligence Scale (MOITIS). 228 primary and secondary school teachers in Serbia (87.7% female; average age 42.79 years) took part in the study. The results of factor analysis suggest the existence of two factors on both scales: incremental theory and entity theory. Further analysis showed that both factors of the ITIS and MOITIS scales have satisfactory psychometric properties. Significant differences were detected between primary and secondary school teachers on the ITIS scale. More specifically, among teachers of science subjects, mathematics and medical subjects the attitude that intelligence is a fixed trait is more pronounced than among teachers of the arts, humanities and social sciences.

Geriatric Femoral Neck Fractures: Hemiarthroplasty Implant Trends Across a Health System From 2006 to 2018.

Introduction:Hemiarthroplasty is increasingly used for the treatment of geriatric femoral neck fractures in an effort to optimize value-based care. The current American Association of Orthopaedic Surgeons (AAOS) guidelines released in 2014 for the treatment of geriatric hip fractures recommend the utilization of monopolar cemented constructs. The purpose of this study was to evaluate hip hemiarthroplasty implant cost variability and implant selection trends from 2006 to 2018.Materials and Methods:A retrospective review of 940 geriatric hip fractures treated with hemiarthroplasty was conducted across 3 institutions from 2006 to 2018. Variables examined were construct type, surgeon, operative time, patient mortality, and implant cost. Statistical analysis consisted of multigroup comparative tests and multiple linear regression analyses to evaluate correlative measures.Results:The study population was 85.0 ± 7.9 years of age with a body mass index of 24.0 ± 5.5. A total of 33 (3.5%) patients were deceased at the 90-day postoperative mark and 45 (4.8%) patients at the 1-year mark. There was no statistical difference in terms of mortality between the 4 implant cohorts at the 90-day mark (P = .56) and 1-year mark (P = .24). The bipolar press-fit construct was the most expensive, US$3900.61 ± US$2607.54, and the monopolar cemented construct was the least expensive, US$2618.68 ± US$1834.16. The mean operative time was 6 minutes greater for press-fit implants, 93.6 ± 32.0, than cemented implants, 87.1 ± 33.6 (P = .02). The use of monopolar cemented implants increased from 12.1% to 83.3%, while bipolar press-fit decreased from 57.6% to 4.6% from 2013 to 2018.Discussion:The use of a bipolar and/or press-fit implant significantly increases construct cost despite little evidence in the literature of improved outcomes. Contrary to previous research, cemented implants do not increase the operative time.Conclusions:Encouragingly, selection of the most cost-conscience implant, monopolar cemented, has been increasing since 2014, which may reflect the influence of current AAOS guidelines.Level of Evidence:Diagnostic Level III.

Middle alternatives and measurement validity: a recommendation for survey researchers

ABSTRACTQuestionnaires routinely measure unipolar and bipolar constructs using rating scales. Such rating scales can offer odd numbers of points, meaning that they have explicit middle alternatives, or they can offer even numbers of points, omitting the middle alternative. By examining four types of questions in six national or regional telephone surveys, this paper found that omitting the middle alternative and forcing respondents to pick a side compromised data quality, for questions presenting two conditions with middle option ‘about equally,’ and for quasi-bipolar questions with middle option ‘fair.’ In addition, omitting the middle alternative never helped improve data quality for a variety of unipolar questions. Lastly, there is a marginally significant improvement in terms of data quality for bipolar questions with middle option ‘neither good nor bad’ when offering a follow-up asking whether they lean one way or the other or whether they are genuinely in the middle.

Self-Control and Weight-Loss Practices: An Exploration of Repertory Grid Constructs

Attempting weight loss is an increasingly common behavior for many people and a variety of practices are used. However, lapses in self-control may hinder progress. This study explores how women construe their weight-loss practices. In 10 semistructured interviews, the repertory grid technique (RGT) was used to explore elicited bipolar constructs using weight-loss practices as elements. Qualitative interpretation of the grids highlighted the fundamentally different ways self-control was seen as being enhanced. The amount of weight to be lost and self-esteem issues were interpreted as impacting expectations of increased self-control from practices. Suggestions for future research into these relationships are outlined.

Construction of an instrument to evaluate the user eXperience of a group of co-creators in the upstream innovation process

The first part of this paper presents a theoretical model, named UX-FFE, which combines a user eXperience (UX) approach with an upstream innovation process. The main interest of this UX-FFE model is that it allows to evaluate the social aspect of the upstream innovation process, which may be detrimental to the success of radical innovation projects in mature companies. The second part presents the outcomes of the experiment of the model application for the ideation stage of the upstream innovation. The objective of this experiment is to evaluate how much the designed bipolar mixed-method instrument and construct are reliable enough. Finally, the results permit, from the original structure of the UX-FFE model, to construct an instrument UXi dedicated to evaluate the user eXperience of co-creators in ideation stage.
