Comparison of π(BB)⋯M bond and luminescence behavior of group 11/12 metal π‐diborene complexes: Theoretical investigation
Authors: Sun Chenfei , Li Zhendong , Lu Bin , Li Qingzhong , Li Xiaoyan 
Published: June 2022

AbstractTransitional metal (TM) π‐diborene complexes have similar structures to those side‐on‐bound TM‐π‐olefin complexes, while their luminescence behaviors are distinctly different. In this work, the natures of the π(BB)⋯TM bonds in π‐diborene(1)⋯MCl (M = Cu, Ag, and Au) and π‐diborene(2)⋯M′Cl2 (M′ = Zn, Cd, and Hg) have been investigated and compared based on EDA, AIM, ELF, NCI, NBO, and ETS‐NOCV analysis as well as their UV/Vis spectra have been predicted. The calculated results show that the π(BB)⋯M/M′ bonds are strong covalent bonds, the orbital interactions in π(BB)⋯M′ (M′ = Zn, Cd, and Hg) are more dominant than those in π(BB)···M (M = Cu, Ag, and Au) bonds. The π(BB)⋯M/M′ interactions belong to the Dewar–Chatt–Duncanson model, the back donations of the M′Cl2 in π‐diborene(2)⋯M′Cl2 are less than those of MCl in π‐diborene(1)⋯MCl. Both π‐diborene(1)⋯MCl and π‐diborene(2)⋯M′Cl2 can produce blue luminescence, the luminescence intensity of former complexes are stronger than the latter complexes.
Toward characterizing locally common graphs

Published: June 2022

AbstractA graph is common if the number of monochromatic copies of in a 2‐edge‐coloring of the complete graph is asymptotically minimized by the random coloring. The classification of common graphs is one of the most intriguing problems in extremal graph theory. We study the notion of weakly locally common graphs considered by Csóka, Hubai, and Lovász [arXiv:1912.02926], where the graph is required to be the minimizer with respect to perturbations of the random 2‐edge‐coloring. We give a complete analysis of the 12 initial terms in the Taylor series determining the number of monochromatic copies of in such perturbations and classify graphs based on this analysis into three categories:Graphs of Class I are weakly locally common.
Graphs of Class II are not weakly locally common.
Graphs of Class III cannot be determined to be weakly locally common or not based on the initial 12 terms.

As a corollary, we obtain new necessary conditions on a graph to be common and new sufficient conditions on a graph to be not common.
Characterizing pedagogical decision points in sense‐making conversations motivated by scientific uncertainty
Authors: Watkins Jessica , Manz Eve 
Published: June 2022

AbstractScience education researchers have highlighted how uncertainty can foster meaningful scientific sense‐making, supporting students to re‐evaluate their understandings of scientific phenomena and pursue deeper causal accounts. However, facilitating whole‐class conversations motivated by uncertainty is complex and challenging, calling for further descriptions of the pedagogical work involved for teachers. In this study, we consider recurring pedagogical decision points as a way to get a handle on how teachers orchestrate classroom conversations and improvise to respond to students' reasoning. To examine these decision points, we analyzed five classroom episodes where classroom communities transformed a student's expression of uncertainty into an episode of collective, scientific sense‐making. Across these episodes, we found that teachers needed to make decisions around (1) whether to make space for an uncertainty, (2) how to transform an uncertainty into a collective problem, (3) which elements to fix and which to leave open, (4) when and how to support the class to evaluate their accounts, (5) whether to make space for and/or mark new goals. Using detailed analyses of two episodes, along with short descriptions of the others, we illustrate how these decision points emerged, the different choices teachers made, and how these decisions shaped the trajectories of the classroom conversations.
Managerial political power and the reallocation of resources in the internal capital market
Authors: Keum Dongil Daniel 
Published: June 2022

AbstractResearch SummaryWe examine how managers' political power reallocates resources in the internal capital market. By shifting the focus from financial to firm‐specific, non‐financial resources that are difficult to evaluate and zero‐sum in nature, we revise the prevailing view that managers' political power plays a significant yet contingent role under financial constraint and weak governance. We instead characterize managerial political power as an intrinsic, inescapable determinant of internal competition and resource allocation. Our research design links sentence‐by‐sentence, qualitative analyses of the legal opinion delivered as breaking news during the corruption trials involving a key executive at Samsung group with minute‐level shifts in share prices. This study presents a politics‐based theory of the internal capital market and highlights the methodological potential of quantitative case studies.Managerial SummaryManagerial politics presents a vexing yet persistent reality of organizational life and the inter‐divisional competition for resources. We attribute its pervasiveness to the contest over non‐financial resources with fuzzy ownership and significant yet uncertain value, such as bargaining power over internal transfer pricing, managerial attention, and control over new business opportunities. Because of the zero‐sum dynamics of these non‐financial resources and their constant scarcity, political contests cannot be suppressed through the provision of financial slack or agency controls and even extend to family members. Appointing rival managers along clearly separated lines of businesses may curb, but not eliminate, managerial politics. We show that investors are acutely aware of the value of managers' political power and make investment decisions based on them.

Published: June 2022

AbstractA 2‐year‐old, female spayed Airedale terrier presented for evaluation of a heart murmur noted during an annual wellness examination. Physical examination revealed a grade IV/VI, left basilar systolic heart murmur. The remaining physical examination was unremarkable. Thoracic radiographs and an echocardiogram were performed. Radiographic findings included right‐sided cardiomegaly, enlargement of the pulmonic arch and enlargement of the caudal lobar pulmonary arteries. An approximately 2.8 cm (apicobasilar dimension) ostium primum atrial septal defect was observed on echocardiography. The dog was discharged with conservative therapy of pimobendan (5 mg PO q12h). As of the most recent recheck, 3 years after initial diagnosis, the patient's heart size remained static.

Published: June 2022

Significance StatementIn the management of natural resources and biodiversity, humans and nature have traditionally been considered as two distinct systems, one controlling the other. The concept of socio-ecosystems allows a more integrated approach, in which humans and nature are recognized as interdependent. However, this new perspective does not necessarily eliminate a distinction between humans and nature, or even a hierarchy of humans over nature. This chapter aims to raise awareness of the potential human–nature dualism in socio-ecosystem approaches. Other research fields have adopted different approaches regarding human–nature integration versus dualism, offering a window on the advantages and limitations of various positions. We also discuss how methodological choices are important to translate human–nature integration or dichotomy depending on the study aim.
Layout optimization of long-span structures subject to self-weight and multiple load-cases
Authors: Fairclough Helen E. , Gilbert Matthew 
Published: June 2022

AbstractLayout optimization provides a powerful means of identifying materially efficient structures. It has the potential to be particularly valuable when long-span structures are involved, since self-weight represents a significant proportion of the overall loading. However, previously proposed numerical layout optimization methods neglect or make non-conservative approximations in their modelling of self-weight and/or multiple load-cases. Combining these effects presents challenges that are not encountered when they are considered separately. In this paper, three formulations are presented to address this. One formulation makes use of equal stress catenary elements, whilst the other two make use of elements with bending resistance. Strengths and weaknesses of each formulation are discussed. Finally, an approach that combines formulations is proposed to more closely model real-world behaviour and to reduce computational expense. The efficacy of this approach is demonstrated through application to a number of 2D- and 3D-structural design problems.

Abstract
Purpose

Oral processing behaviour may contribute to individual differences in glycaemic response to foods, especially in plant tissue where chewing behaviour can modulate release of starch from the cellular matrix. The aim of this study was to assess the impact of chewing time of two starch based foods (brown rice and chickpeas) on bolus properties, in vitro starch digestion and postprandial glycaemic excursion in healthy subjects.

Methods
In a cross-over trial participants (n = 26) consumed two carbohydrates-identical test meals (brown rice: 233 g; chickpeas: 323 g) with either long (brown rice: 41 s/bite; chickpeas: 37 s/bite) or short (brown rice: 23 s/bite; chickpeas: 20 s/bite) chewing time in duplicate while glycaemic responses were monitored using a continuous glucose monitoring device. Expectorated boli were collected, then bolus properties (number, mean area, saliva amylase activity) and in vitro starch digestion were determined.

Results
Longer chewing resulted in significantly (p < 0.05) more and smaller bolus particles, higher bolus saliva uptake and higher in vitro degree of intestinal starch hydrolysis (DH_Schewing time%) than shorter chewing for both foods (brown rice: DH_S%23 s = 84 ± 4% and DH_%S41s = 90 ± 6%; chickpeas: DH_S%20 s = 27 ± 3% and DH_%S37s = 34 ± 5%, p < 0.001). No significant effect of chewing time on glycaemic response (iAUC) (p > 0.05) was found for both meals. Brown rice showed significantly and considerably higher in vitro degree of intestinal starch hydrolysis and glycaemic response (iAUC) than chickpeas regardless of chewing time. No significant correlations were observed between bolus properties and in vitro starch hydrolysis or glycaemic response (p > 0.05).

Conclusion
Differences in the innate structure of starch based foods (brown rice compared to chickpeas) have a larger effect on postprandial glucose response than differences in mastication behaviour although oral processing behaviour showed consistent effects on bolus properties and in vitro starch digestion.

Published: June 2022

Abstract
Purpose
The present study aimed to assess the feasibility, safety and accuracy of navigated spinopelvic fixation with focus on S2-alar-iliac screws (S2AIS) and tricortical S1 pedicle screw implantation with the use of high-resolution three-dimensional intraoperative imaging and real-time spinal navigation.

Methods
Patients undergoing navigated intraoperative CT-based spinopelvic stabilization between January 2016 and September 2019 were included. Pelvic fixation was achieved by implantation of S2AIS or iliac screws (IS). S1 screws were implanted with the goal of achieving tricortical purchase. In all cases, instrumentation was performed with real-time spinal navigation and intraoperative screw positioning was assessed using intraoperative computed tomography (iCT), cone-beam CT (CBCT) and robotic cone-beam CT (rCBCT). Screw accuracy was evaluated based on radiographic criteria. To identify predictors of complications, univariate analysis was performed.

Results
Overall, 52 patients (85%) received S2AIS and nine patients (15%) received IS instrumentation. Intraoperative imaging and spinal navigation were performed with iCT in 34 patients, CBCT in 21 patients and rCBCT in six patients. A total number of 10/128 (7.8%) iliac screws underwent successful intraoperative correction due to misalignment. Tricortical purchase was successfully accomplished in 58/110 (53%) of the S1 screws with a clear learning curve in the course of time. S2AIS implantation was associated with significantly fewer surgical side infection-associated surgeries.

Conclusions
Real-time navigation facilitated spinopelvic instrumentation with increasing accuracy of S2AIS and tricortical S1 screws. Intraoperative imaging by iCT, CBCT or rCBCT permitted screw assessment with the chance of direct navigated revision of misplaced iliac screws to avoid secondary screw revision surgery.
The case for the Humanities Citation Index (HuCI): a citation index by the humanities, for the humanities
Authors: Colavizza Giovanni , Peroni Silvio , Romanello Matteo 
Published: June 2022

AbstractCitation indexes are by now part of the research infrastructure in use by most scientists: a necessary tool in order to cope with the increasing amounts of scientific literature being published. Commercial citation indexes are designed for the sciences and have uneven coverage and unsatisfactory characteristics for humanities scholars, while no comprehensive citation index is published by a public organisation. We argue that an open citation index for the humanities is desirable, for four reasons: it would greatly improve and accelerate the retrieval of sources, it would offer a way to interlink collections across repositories (such as archives and libraries), it would foster the adoption of metadata standards and best practices by all stakeholders (including publishers) and it would contribute research data to fields such as bibliometrics and science studies. We also suggest that the citation index should be informed by a set of requirements relevant to the humanities. We discuss four such requirements: source coverage must be comprehensive, including books and citations to primary sources; there needs to be chronological depth, as scholarship in the humanities remains relevant over time; the index should be collection driven, leveraging the accumulated thematic collections of specialised research libraries; and it should be rich in context in order to allow for the qualification of each citation, for example, by providing citation excerpts. We detail the fit-for-purpose research infrastructure which can make the Humanities Citation Index a reality. Ultimately, we argue that a citation index for the humanities can be created by humanists, via a collaborative, distributed and open effort.
Deciding the feasibility of a booking in the European gas market is coNP-hard
Authors: Thürauf Johannes 
Published: June 2022

AbstractWe show that deciding the feasibility of a booking () in the European entry-exit gas market is coNP-hard if a nonlinear potential-based flow model is used. The feasibility of a booking can be characterized by polynomially many load flow scenarios with maximum potential-difference, which are computed by solving nonlinear potential-based flow models. We use this existing characterization of the literature to prove that is coNP-hard by reducing to the infeasibility of a booking. We further prove that computing a potential-difference maximizing load flow scenario is $${\textsc {NP}}$$
NP
-hard even if we can determine the flow direction a priori. From the literature, it is known that can be decided in polynomial time on trees and a single cycle. Thus, our hardness result draws the first line that separates the easy from the hard variants of and finally answers that is hard in general.

Abstract
Angiogenesis is a hallmark of cancer development. This study sought to determine the recommended dose of aflibercept, a recombinant fusion protein targeting VEGF-A, VEGF-B and placental growth factor (PlGF), combined with docetaxel in Japanese patients with advanced solid malignancies. This phase I study was planned to include 12 patients following a 3 + 3 algorithm to determine the maximum tolerated dose of aflibercept combined with docetaxel in patients with metastatic or unresectable solid tumors (trial registration: NCT00545246). Docetaxel (75 mg/m2 every 3 weeks or 60 mg/m2 after protocol amendment) was combined with escalating doses of aflibercept (2, 4 and 6 mg/kg every 4 weeks). Free and VEGF-bound aflibercept were measured to assess free aflibercept in excess of the VEGF-bound form. At the starting dose of the combination, 3 of 6 patients treated experienced febrile neutropenia. After reducing the docetaxel dose to 60 mg/m2 in step 2 and permitting therapeutic granulocyte colony-stimulating factor (G-CSF) use, 2 of 3 patients in both cohorts experienced febrile neutropenia. Five patients (42%) had a partial response and 4 patients had stable disease (33%). Free aflibercept in excess of the VEGF-bound form was not maintained at this dose level. The dose limiting toxicity (DLT) of aflibercept combined with docetaxel was febrile neutropenia, which occurred in 2 of 3 Japanese patients at the lowest aflibercept dose level (2 mg/kg) combined with docetaxel (60 mg/m2) and therapeutic G-CSF use. A recommended dose for further studies was not determined because of the DLT at the starting dose.
Social Investment Policies and Childbearing Across 20 Countries: Longitudinal and Micro-Level Analyses
Authors: Billingsley Sunnee , Neyer Gerda , Wesolowski Katharina 
Published: June 2022

AbstractThis study analyses the influence of family policies on women’s first and second births in 20 countries over the period 1995 to 2007. Welfare states have shifted towards social investment policies, yet family policy–fertility research has not explicitly considered this development. We distinguish between social investment-oriented and passive support that families may receive upon the birth of a child and consider changes in policies over time. These indicators are merged with fertility histories provided by harmonized individual-level data, and we use time-conditioned, fixed effects linear probability models. We find higher social investment-oriented support to be correlated with increased first birth probabilities, in contrast to passive family support. First birth probabilities particularly declined with higher passive family support for women over age 30, which points to a potential increase in childlessness. Social investment-oriented support is positively related to first and second births particularly for lower-educated women and has no relationship to childbirth for highly educated women, countering the Matthew-effect assumptions about social investment policies. Passive support is negatively related to second births for post-secondary educated women and those who are studying. Family policies that support women’s employment and labour market attachment are positively linked to family expansion and these policies minimize educational differences in childbearing.
Geographical structure of the local segregation of migrants in (sub)urban China
Authors: He Qiong , Musterd Sako , Boterman Willem 
Published: June 2022

AbstractUnprecedented urbanisation in China has profoundly reshaped the country’s social-spatial structure. Owing to economic suburbanisation and urban redevelopment processes, migrants coming from rural areas are increasingly concentrated in suburbs rather than city centres. Against this backdrop, this paper focuses on residential segregation between migrants and locals, and on geographical (re)structuring between the city centre and suburb. Theil’s H Index is used to disaggregate the migrant segregation of each municipality into a within-suburb, a within-centre and a between-centre-suburb component. We use Census data for 258 municipalities in 2000 and 2010; we find that migrant segregation increased in this period. We ascribe this to the increasing segregation of migrants in suburban areas, which offsets the increasingly balanced distribution of migrants between the city centre and suburb. Segregation in city centres also increased slightly in this period. Unexpectedly, less economically developed municipalities, defined by their per capita GDP, tend to be more segregated than their more developed counterparts. Less developed municipalities also have a higher level of suburban employment and housing opportunities in the whole municipality, but feature more segregated suburban spaces and a polarised distribution of migrants between the centre and suburb.
Organizational Capabilities for AI Implementation—Coping with Inscrutability and Data Dependency in AI
Authors: Weber Michael , Engert Martin , Schaffer Norman , Weking Jörg , Krcmar Helmut 
Published: June 2022

AbstractArtificial Intelligence (AI) implementation incorporates challenges that are unique to the context of AI, such as dealing with probabilistic outputs. To address these challenges, recent research suggests that organizations should develop specific capabilities for AI implementation. Currently, we lack a thorough understanding of how certain capabilities facilitate AI implementation. It remains unclear how they help organizations to cope with AI’s unique characteristics. To address this research gap, we employ a qualitative research approach and conduct 25 explorative interviews with experts on AI implementation. We derive four organizational capabilities for AI implementation: AI Project Planning and Co-Development help to cope with the inscrutability in AI, which complicates the planning of AI projects and communication between different stakeholders. Data Management and AI Model Lifecycle Management help to cope with the data dependency in AI, which challenges organizations to provide the proper data foundation and continuously adjust AI systems as the data evolves. We contribute to our understanding of the sociotechnical implications of AI’s characteristics and further develop the concept of organizational capabilities as an important success factor for AI implementation. For practice, we provide actionable recommendations to develop organizational capabilities for AI implementation.
