Do command‐and‐control environmental regulations realize the win‐win of “pollution reduction” and “efficiency improvement” for enterprises? Evidence from China
Authors: Li Jianpei , Huang Jierui , Li Bowen 
Published: December 2023

AbstractWe use the DID method to estimate whether the binding pollution control policy can achieve both “pollution reduction” and “efficiency enhancement” for industrial enterprises after implementing this command‐and‐control environmental regulation of the eleventh Five‐Year Plan in China. We also analyze its influence mechanism in detail. It has been shown that (1) Constrained by binding pollution control policies, enterprises could reduce their pollutant emissions but simultaneously suppress their total factor productivity (TFP), which indicates that command‐and‐control environmental regulations do not achieve both “pollution reduction” and “efficiency gains” for firms. (2) The mechanism analysis shows that under the constraint of the binding pollution control policy, enterprises increase the pollution treatment at the front end of production, such as investment in environmental protection facilities, and adjust the production schedule, such as pollution treatment at the end of production. These pollution treatment measures reduce pollutant emissions while bringing “compliance costs” to enterprises. However, the “innovation compensation effect” fails to compensate for the “compliance cost” brought by pollution control. (3) Further study finds that the binding pollution control policy effectively reduces the pollutant emissions of enterprises with low financing constraints.

Published: December 2023

AbstractResearch SummaryWe contend that entrepreneurial judgment governance (EJG) is a profound yet poorly understood process in which firms sense, seize, and transform opportunities related to digital transformation. Grounded in a rich, multi‐case study of six large incumbent firms, we conceptualize and examine how firms change EJG through three phases: recognizing, distributing, and orchestrating. We find that EJG adaptation is at the heart of why some firms succeed in responding to the challenges associated with digital transformation while others fail. Implications and opportunities for future research are discussed.Managerial SummaryEntrepreneurial judgment governance (EJG) is central to explaining why some firms succeed in digital transformation (DT) whereas others do not. EJG determines who has the right to exercise entrepreneurial judgment (EJ) about allocating and using resources to address new opportunities. As distinct types of uncertainties require distinct EJ features, established firms face the challenge of EJG adaptation to the unique DT uncertainties. Based on a multiple‐case study, we offer a three‐stage framework that facilitates and expedites EJG adaptation to DT. Furthermore, our study highlights that strategic leaders who fail to comprehend the need for changes in EJG, neglect to establish an EJG architecture aligned with DT goals or overlook implementing necessary adjustments internally and externally, may hinder positive DT outcomes.
How does economic freedom influence public health? Evidence from U.S. cities

Published: December 2023

AbstractAlthough there is substantial agreement how microeconomic forces—income, risk aversion—shape public health outcomes, there is substantial disagreement about the relationship between macroeconomic forces—market liberalization and economic freedom—on public health. In this paper, we investigate the relationship between public health, economic freedom, and wealth using a large sample of metropolitan‐level data from the United States. We find that economic freedom does have a statistically significant and positive impact on general, physical, and mental health, but the overall results are small in magnitude. When we disaggregate the three areas of economic freedom, we find that areas with lower government spending and freer labor markets have the strongest positive effect on physical and mental health. However, our results are strongest for the richest group of respondents, suggesting that the economic freedom‐health relationship is perhaps indirect, and shown through income.

AbstractCode comment generation, which attempts to summarize the functionality of source code in textual descriptions, plays an important role in automatic software development research. Currently, several structural neural networks have been exploited to preserve the syntax structure of source code based on abstract syntax trees (ASTs). However, they can not well capture both the long‐distance and local relations between nodes while retaining the overall structural information of AST. To mitigate this problem, we present a prototype tool titled PyScribe, which extends the Transformer model to a new encoder‐decoder‐based framework. Particularly, the triplet position is designed and integrated into the node‐level and edge‐level structural features of AST for producing Python code comments automatically. This paper, to the best of our knowledge, makes the first effort to model the edges of AST as an explicit component for improved code representation. By specifying triplet positions for each node and edge, the overall structural information can be well preserved in the learning process. Moreover, the captured node and edge features go through a two‐stage decoding process to yield higher qualified comments. To evaluate the effectiveness of PyScribe, we resort to a large dataset of code‐comment pairs by mining Jupyter Notebooks from GitHub, for which we have made it publicly available to support further studies. The experimental results reveal that PyScribe is indeed effective, outperforming the state‐ofthe‐art by achieving an average BLEU score (i.e., av‐BLEU) of 0.28.

Published: December 2023

AbstractCesium lead triiodide (CsPbI3) perovskite receives tremendous attention for photovoltaic applications, owing to its remarkable thermal stability and optoelectronic properties. However, realizing the CsPbI3 perovskite with high black‐phase stability and optoelectronic properties remains a significant challenge, which largely affects the photovoltaic performance of perovskite solar cells (PSCs). Herein, aromatic ammonium agents are used to modulate the crystallization of the CsPbI3 perovskite to improve its black‐phase stability and optoelectronic properties for efficient PSCs. Systemically experimental studies and comprehensively theoretical calculations are performed, which reveal that histammonium dihydrochloride (HACl2) could strongly couple with the perovskite during its crystallization, leading to faster nucleation and slower perovskite growth, and thus modulating the crystallization dynamics of the perovskites. Moreover, the residual diammonium cations (HA2+) distributed at the grain boundaries and on the surface of the perovskites can effectively passivate defects through electrostatic interactions, substantially suppressing trap‐assisted nonradiative recombination, and prompting more matched perovskite surface energetics. Consequently, the photovoltaic performance of CsPbI3 PSCs is largely improved because of a combination of enhanced crystallinity and optoelectronic properties of the perovskites. This work offers a new avenue to prepare inorganic perovskites with high optoelectronic properties for photovoltaics.
Static behavior of ribbed folded plate roof under vertical uniform load—Experimental study and meshfree method analysis

Published: December 2023

SummaryFolded plate roofs are widely used in building roofs due to their light weight and high stiffness. However, traditional folded plate roofs are often limited in application due to insufficient stiffness under the current trend of pursuing larger‐span roofs. Ribbed folded plate roofs can effectively solve this problem because ribs not only increase the stiffness of the roof and reduce stress concentration, but they are also easy to be formed into various shapes to meet different needs for buildings. Therefore, the detailed analysis was carried out on a reinforced concrete ribbed folded plate roof (RCRFR) under the vertical uniform load to investigate its static behavior. The bearing capacity, failure mode, load–displacement relationship, and strain variation were obtained through the test. Additionally, based on the finite element (FE) method, not only a comparison was conducted between RCRFR and reinforced concrete ribless folded plate roof (RCLFR), but the influence of material nonlinearity and geometric nonlinearity on the structure was also investigated. Moreover, the bending characteristics of RCRFR under design load were analyzed based on the reproducing kernel particle method. The experimental results showed that this structure had good mechanical properties within the design load. In the overload stage, the concrete on the underside of the structure was severely damaged. Furthermore, the yielding of the ribbed plate's reinforcing bars caused the increased vertical deformation difference between the ribbed plate and the top chord, and the ribbed plate and the central ridge beam. Eventually, the failure of the anchorage of the ribbed plate's reinforcing bars anchored in the central ridge beam and the top chord led to the loss of structural load‐bearing capacity. The FE analysis results demonstrated that ribs enhance the stiffness of the structure, with material nonlinearity having the primary impact and geometric nonlinearity exerting a secondary effect. The meshfree method analysis was in concordance with the experimental results as well as those of the FE analysis.
Multi‐indicator evaluation method of important members of truss string structures
Authors: Liu Wenhao , Zeng Bin , Zhou Zhen , Zheng Yifan 
Published: December 2023

SummaryDuring the past decade, the progressive collapse of structures has received growing attention, and the study of member importance is a key step for investigating the progressive collapse resistance. However, traditional methods for evaluating the member importance usually employ a single indicator, and when multiple indicators are involved, different indicators may generate different member rankings. Moreover, the truss string structure is a multiple super‐stationary structure with many members, and the current studies mainly focus on cable failure, which does not mean that other members are not important. In this study, the initial selection of important members is first performed based on concept evaluation, and then, the alternate path method is used to analyze the progressive collapse resistance of truss string structures; the slope degradation coefficient γ of incremental dynamic analysis curve, load capacity degradation coefficient β, and nested load capacity degradation coefficient β′ are introduced; and the sensitivity coefficient SIj and fragility coefficient VIi are defined with axial force as the structural response. Based on the above five indicators, two cases are conducted to evaluate the member importance. The analysis results show that the cable and the bottom chord member at the support are evaluated as the first‐level important members. Through the analysis of different indicators, it is found that the regularity of the coefficient of each member is inconsistent for different indicators. The results could be one‐sided if the important members were evaluated by a single indicator only. In addition, the second‐level important members of truss string structures are evaluated by multi‐indicator analysis. Finally, the nominal progressive collapse resistance of truss string structures is given based on the importance coefficient of the first‐ and second‐level important members.
A multimodal translingual approach to study a young learner's willingness to communicate
Authors: Wong Nickie 
Published: December 2023

AbstractContrary to prevailing research on willingness to communicate (WTC) which treats spoken second language (L2) as the predominant indicator of WTC, this study examines a young English as a second language (ESL) learner's WTC expressed through multimodal means and her utilization of multimodal and multilingual resources for mediating WTC in translingual environments. Data were collected from videotaped ESL lessons and an interview. Adopting a multimodal conversation analysis (CA) approach, this cross‐disciplinary study analyzes the ESL novice's WTC expressions in two communicative settings: small‐group interactions in ESL class and a multilingual triad conversation in an interview. Findings reveal that (1) gestural WTC display can signify more than one's intention to enter discourse, (2) contrary to previous WTC studies, first language (L1) use can indicate L2 WTC, and (3) the learner used diverse semiotic resources to mediate WTC and sustain discursive engagement. Implications are discussed with respect to the findings. This study extends the understanding of WTC beyond spoken L2 expressions, emphasizing embodied display and L1 use in the learner's communicative repertoire. Additionally, it sheds light on the learner's strategic use of multimodal resources to sustain engagement in translingual environments, contributing to the broader field of language education and multimodal analysis.

Published: December 2023

AbstractThis research aimed to produce thermochromic composite filaments by utilizing poly(lactic acid) (PLA) as a matrix and two distinct thermochromic additives (red and yellow colors). To produce thermochromic composite filaments with ratios ranging from 10 to 40 phr, different quantities of a thermochromic masterbatch were integrated into the PLA matrix through an extrusion process. The physical, mechanical, thermal properties, and thermochromic behavior of the composite filaments were further examined. The results indicated that the thermochromic additives had minimal impact on thermal and mechanical properties, while also revealing a two‐phase separation between the smooth matrix and the spherical particle additives in the thermochromic composite filaments. Moreover, the analysis of thermochromic behavior revealed that an increase in the ratio of thermochromic masterbatches led to more pronounced coloration and clearer color changes, especially with red and yellow thermochromics indicating temperature variations below 22°C and over 65°C, respectively. The sample containing 40 phr exhibited the most intense color and noticeable color change. Furthermore, these thermochromic composite filaments can be utilized to 3D print various prototype products.Highlights
Thermochromic bioplastic composite filaments for 3D printing were successfully prepared.
The thermochromic behavior analysis unveiled vivid coloration with distinct and more pronounced color changes.

Published: December 2023

AbstractOne of the most essential tasks in probabilistic damage tolerance assessment is to describe the scatter in crack growth accurately. This study proposes a stochastic model of the crack growth rate, which calculates the critical parameters of a random distribution accurately by combining the Markov chain and data fitting algorithms. The proposed method is validated by the crack growth test data of Ni‐based superalloy GH4710Li at 550°C. The validation results show that the proposed method is a robust and efficient stochastic model for the crack growth rate.

Authors: Heltberg Therese , Krogh Andreas Hagedorn , Kyne Karena 
Published: December 2023

AbstractFaced with increasingly unpredictable, dynamic, and complex threats and adversaries, European defense forces experiment with design thinking as an alternative to more traditional military planning perspectives and methodologies. Reviewing the current state of military design in Europe, this chapter provides an overview of recent design developments in doctrines, European military organizations, and European defense colleges. It explains these developments and provides examples of recent design practices in a European military context. Currently, military design is still a niche in Europe, but the chapter shows how the design approach continues to evolve as military scholars, strategists, and planners explore and develop new and innovative ways of deploying design methodologies in military practice.
From Particular Sociologies to Interdisiplinary Studies
Authors: Zabludovsky Gina 
Published: December 2023

AbstractAs in other parts of the world, at the beginning of the 1980s, sociology in Mexico confronted new theoretical and methodological challenges. From 1980 to 2000, sociology passed through an increasing specialization, a renewed attention to the study of new actors, social identities, subjectivities, and social movements. In line with the transformation of Mexico’s democratic institutions, sociology studies centered on the state, democracy, power, and the political system. During the first decades of the new century, facing the new complex, national, and global circumstances, such as increasing violence, the ecological problems, new migrations and the pandemic, sociology made a shift from the previous emphasis on specialization towards interdisciplinary studies with a more comprehensive approach.
Technologieakzeptanz in der Digitalisierung der ambulanten Pflege – eine Fallstudie
Authors: Frings Katrin , Güsken Sarah Ranjana , Schütz Benedikt , Bitter-Krahe Jan 
Published: December 2023

ZusammenfassungIn den letzten Jahren ist die Arbeitsbelastung in der deutschen Pflegebranche durch einen zunehmenden Fachkräftemangel und den gleichzeitig stattfindenden demografischen Wandel massiv gestiegen. Zur Reduktion der Arbeitsbelastung werden Arbeitsprozesse zunehmend digitalisiert. Allerdings zeigt sich in ausbleibender Technikakzeptanz die Folge eines unzureichenden Einbezugs von Pflegekräften und ihren heterogenen Kompetenzprofilen in diesem Digitalisierungsprozess. Zur Erweiterung eines fallbeispielbezogenen pflegespezifischen Technologieakzeptanzmodells wurde eine qualitative Studie mittels teilstrukturierter Interviews mit zwölf ambulanten Pflegekräften durchgeführt. Durch eine qualitative Inhaltsanalyse dieser Interviews konnten neun weitere, die Nutzungsintention von digitalen Technologien in der Pflege beeinflussenden Faktoren herausgearbeitet werden, z. B. Passung der digitalen Technologie zum Anwendungskontext und Überwachung durch digitale Technologien. Die Ergebnisse der Studie tragen dazu bei, branchenspezifische Faktoren für eine erfolgreiche Technologieimplementierung zu definieren. Diese können auch als Grundlage einer digitalen Kompetenzentwicklung ambulanter Pflegekräfte dienen.
Expansion and Collapse of Spherically Symmetric Isotropic Elastic Bodies Surrounded by Vacuum
Authors: Sideris Thomas C. 
Published: December 2023

AbstractA class of isotropic and scale-invariant strain energy functions is given for which the corresponding spherically symmetric elastic motion includes bodies whose diameter becomes infinite with time or collapses to zero in finite time, depending on the sign of the residual pressure. The bodies are surrounded by vacuum so that the boundary surface forces vanish, while the density remains strictly positive. The body is subject only to internal elastic stress.

-dimensional Einstein equations with negative cosmological constant coupled to a spherically symmetric, massless scalar field and study perturbations around the anti-de Sitter spacetime. We derive the resonant systems, pick out vanishing secular terms and discuss issues related to small divisors. Most importantly, we rigorously establish (sharp, in most of the cases) asymptotic behaviour for all the interaction coefficients. The latter is based on uniform estimates for the eigenfunctions associated to the linearized operator as well as on some oscillatory integrals.

Published: December 2023

AbstractThe current study aims to differentiate, morphologically, between the masticatory muscles in black-tip sharks and shovelnose ray fish, which control the opening and closure of jaws. This work was applied to four specimens of each species, obtained from the Red Sea in Suez. Anatomical dissection was conducted on the cephalic region is order to expose the musculature. The obtained results illustrate each muscle's position, origin, and insertion. The common muscles involved in the feeding of both species were the muscles of mandibular arch: adductor mandibulae, levator palatoquadrati, while the muscles of hyoid arch were levator hyomandibulae, also the hypobranchial arch contained coracomandibularis, coracohyoideus, and coracoarcualis. All muscles of the jaws are responsible for the abduction of mouth except Adductor mandibulae M, Intermandibularis M. involved in closing the mouth, in addition, Preorbitalis M. assists in protruding of upper jaw.

AbstractWe prove a non-extinction result for Fleming–Viot-type systems of two particles with dynamics described by an arbitrary symmetric Hunt process under the assumption that the reference measure is finite. Additionally, we describe an invariant measure for the system, we discuss its ergodicity, and we prove that the reference measure is a stationary measure for the embedded Markov chain of positions of the surviving particle at successive branching times.
Server Cloud Scheduling
Authors: Maack Marten , Meyer auf der Heide Friedhelm , Pukrop Simon 
Published: December 2023

AbstractConsider a set of jobs connected to a directed acyclic task graph with a fixed source and sink. The edges of this graph model precedence constraints and the jobs have to be scheduled with respect to those. We introduce the server cloud scheduling problem, in which the jobs have to be processed either on a single local machine or on one of infinitely many cloud machines. For each job, processing times both on the server and in the cloud are given. Furthermore, for each edge in the task graph, a communication delay is included in the input and has to be taken into account if one of the two jobs is scheduled on the server and the other in the cloud. The server processes jobs sequentially, whereas the cloud can serve as many as needed in parallel, but induces costs. We consider both makespan and cost minimization. The main results are an FPTAS for the makespan objective for graphs with a constant source and sink dividing cut and strong hardness for the case with unit processing times and delays.
