AbstractIn the last few decades, rising prices of agricultural commodities have been an area of concern for most countries owing to high population growth, increased unemployment, and per capita food needs. The current study intends to examine the positive and negative shocks of agricultural product prices, credit disbursement, and the labor force’s impact on the agricultural growth of Pakistan. The nonlinear autoregressive distributed lag (NARDL) method was applied using secondary data sources from 1970 to 2018. The results revealed that positive and negative price shocks contribute positively to agriculture growth; however, positive price shock has a more stimulating effect than negative prices. Furthermore, credit disbursement and labor force significantly positively impact agricultural value added in the short and long run. Finally, the study’s findings have far-reaching consequences for policymakers dealing with Pakistan’s asymmetric relationship between agricultural credit disbursement, commodity prices, and agricultural growth.
Which kind of board benefits more from the relationship between entrepreneurial orientation and radical innovation? The asymmetric roles of board characteristics in China
Authors: Liu Yexin , Wu Yecheng , Wu Weiwei 
Published: July 2023

AbstractRadical innovation is necessary for firms to transform existing markets or create new ones, which has critical impact on firm performance. Therefore, there is a need to explore how radical innovation can be successfully achieved. Entrepreneurial orientation reflects a firm’s willingness to be innovative, proactive and risk-taking, which has been recognized as a key factor contributing to firm innovation. However, the specific focus on the relationship between entrepreneurial orientation and radical innovation is very limited. This paper therefore investigates how entrepreneurial orientation affects radical innovation by considering the contingency effects of board characteristics. Using the panel data of listed manufacturing firms in China from 2013 to 2019, this paper found that entrepreneurial orientation has a significant positive impact on radical innovation. Furthermore, different board characteristics play asymmetric moderating roles in that relationship in such a way that CEO duality and board independence play positive moderating roles, while board ownership and board size play negative moderating roles. This paper contributes to the entrepreneurial orientation literature by providing a finer-grained understanding of the role of entrepreneurial orientation on radical innovation. This paper also contributes to the corporate governance literature by revealing the asymmetric contingency effects of different board characteristics.
InP/InGaAs/AlGaAs quantum-well semiconductor laser with an InP based 1550 nm n-GaAsSb single waveguide structure

Published: July 2023

A n-GaAsSb single waveguide layer semiconductor laser with an InP/In0.55Ga0.45As/AlGaAs asymmetrical barrier is designed in order to improve output power, which not only reduces optical loss in the p-region but also effectively suppresses carrier leakage. The results show that a GaAsSb single waveguide structure almost completely shifts the optical field to the n-region, which reduces the absorption of photons by holes. When the injected current is 1 A, the device’s optical loss decreases from 15.60 to 13.20 cm−1. Ensuring that carrier leakage and internal quantum efficiency are almost unaffected, the InP/In0.55Ga0.45As/AlGaAs asymmetric barrier makes optical loss further reduce. The power of the new-structure device is 0.74 W, and its wall-plug efficiency reaches 70.84%. This structure design will provide both experimental data and theoretical support for the growth of the epitaxial structure of InP-based 1550 nm semiconductor lasers.

Published: July 2023

Abstract
Missing values (MVs) can adversely impact data analysis and machine-learning model development. We propose a novel mixed-model method for missing value imputation (MVI). This method, ProJect (short for Protein inJection), is a powerful and meaningful improvement over existing MVI methods such as Bayesian principal component analysis (PCA), probabilistic PCA, local least squares and quantile regression imputation of left-censored data. We rigorously tested ProJect on various high-throughput data types, including genomics and mass spectrometry (MS)-based proteomics. Specifically, we utilized renal cancer (RC) data acquired using DIA-SWATH, ovarian cancer (OC) data acquired using DIA-MS, bladder (BladderBatch) and glioblastoma (GBM) microarray gene expression dataset. Our results demonstrate that ProJect consistently performs better than other referenced MVI methods. It achieves the lowest normalized root mean square error (on average, scoring 45.92% less error in RC_C, 27.37% in RC_full, 29.22% in OC, 23.65% in BladderBatch and 20.20% in GBM relative to the closest competing method) and the Procrustes sum of squared error (Procrustes SS) (exhibits 79.71% less error in RC_C, 38.36% in RC full, 18.13% in OC, 74.74% in BladderBatch and 30.79% in GBM compared to the next best method). ProJect also leads with the highest correlation coefficient among all types of MV combinations (0.64% higher in RC_C, 0.24% in RC full, 0.55% in OC, 0.39% in BladderBatch and 0.27% in GBM versus the second-best performing method). ProJect’s key strength is its ability to handle different types of MVs commonly found in real-world data. Unlike most MVI methods that are designed to handle only one type of MV, ProJect employs a decision-making algorithm that first determines if an MV is missing at random or missing not at random. It then employs targeted imputation strategies for each MV type, resulting in more accurate and reliable imputation outcomes. An R implementation of ProJect is available at https://github.com/miaomiao6606/ProJect.
LSMMD-MA: scaling multimodal data integration for single-cell genomics data analysis
Authors: Meng-Papaxanthos Laetitia , Zhang Ran , Li Gang , Cuturi Marco , Noble William Stafford , Vert Jean-Philippe 
Published: July 2023

Abstract

Motivation
Modality matching in single-cell omics data analysis—i.e. matching cells across datasets collected using different types of genomic assays—has become an important problem, because unifying perspectives across different technologies holds the promise of yielding biological and clinical discoveries. However, single-cell dataset sizes can now reach hundreds of thousands to millions of cells, which remain out of reach for most multimodal computational methods.

Results
We propose LSMMD-MA, a large-scale Python implementation of the MMD-MA method for multimodal data integration. In LSMMD-MA, we reformulate the MMD-MA optimization problem using linear algebra and solve it with KeOps, a CUDA framework for symbolic matrix computation in Python. We show that LSMMD-MA scales to a million cells in each modality, two orders of magnitude greater than existing implementations.

Children’s Participation in Child Welfare: A Systematic Review of Systematic Reviews
Authors: McCafferty Paul , Mercado Garcia Esther 
Published: July 2023

Abstract
The objective of this research was to conduct a systematic review of systematic reviews related to Article 12 of the UN Convention on the Rights of the Child (UNCRC) as it relates to children and young people involved with child welfare agencies. This systematic review sought to comply with the guidance from the JBI Manual for Evidence Synthesis on umbrella reviews. Fourteen databases were searched using predefined terms. Six hundred seventy-four original hits were retrieved for title and abstract searching after independent searching by the authors. Of those, fourteen were included for full independent reads and all fourteen were selected after discussion. Each systematic review was appraised using an eleven-point quality checklist from JBI. A thematic review was conducted to ascertain the themes across all systematic reviews. Three themes emerged (i) children’s voice is not taken seriously; (ii) relationships are an important determining factor in (un)successful participation; and (iii) the context of participation is important. Our conclusion is that despite mandated UNCRC requirements to involve children and young people within the child protection system, the possibilities for children and young people to express their views remain restricted.
From bazooka to backstop: the political economy of standing swap facilities
Authors: Richtmann Mathis L , Steininger Lea 
Published: July 2023

Abstract
The permanent international lender of last resort consists of a swap line network between six major central banks (C6), centring around the US Federal Reserve. Arguably, this network is a solution to a long-debated problem as it provides public emergency liquidity provision to the world’s largest financial market, the Eurodollar market. Drawing on exclusive interviews with monetary technocrats as well as a textual analysis of Federal Open Market Committee meeting transcripts over the course of 14 years, we reconstruct how this facility came into being. Building on Kalyanpur and Newman (2017) and Braun (2015), we develop an interpretive framework of bricolage to contextualise its formation: in times of crisis, central bankers rely on retrospection, experimentation and creative re-deployment to develop their tools. In non-crisis times, however, the tools that prevail are those that offer what we call ‘bureaucratic familiarity’: the C6 swap line network became a permanent feature of international finance because technocrats had got used to it.
Multiscale model reduction of finite-difference frequency-domain wave modelling in acoustic media
Authors: Jiang Wei , Chen Xuehua , Zhao Qingwei 
Published: July 2023

SUMMARY
Frequency-domain wave modelling can easily describe the visco-acoustic behaviour of wave propagation using frequency-dependent velocities. Conventional finite-difference (FD) modelling in the frequency domain is computationally prohibitive for solving the acoustic Helmholtz equation in complicated and large geological models. To reduce the computational cost of traditional FD Helmholtz solvers, we develop a multiscale FD frequency-domain method that uses multiscale basis functions to significantly reduce the dimension of system matrices associated with the Helmholtz equation. Due to the insufficient accuracy of the first-order multiscale basis functions in the case of strongly heterogeneous models, we introduce the multinode coarse-element scheme into the scalar Helmholtz equation, a scheme previously developed in the extended multiscale finite-element method for vector problems. This multinode scheme enables multiscale basis functions to capture accurate fine-scale medium property variations. We use one homogeneous model and two heterogeneous models to validate our multiscale method for accuracy and computational cost. Numerical results demonstrate that our new approach can significantly reduce the time and memory costs of acoustic wave modelling while maintaining accuracy, indicating the great potential of our multiscale method in large-scale modelling applications.

Published: July 2023

Synopsis
Torpor is an incredibly efficient energy-saving strategy that many endothermic birds and mammals use to save energy by lowering their metabolic rates, heart rates, and typically body temperatures. Over the last few decades, the study of daily torpor—in which torpor is used for &lt;24 h per bout—has advanced rapidly. The papers in this issue cover the ecological and evolutionary drivers of torpor, as well as some of the mechanisms governing torpor use. We identified broad focus areas that need special attention: clearly defining the various parameters that indicate torpor use and identifying the genetic and neurological mechanisms regulating torpor. Recent studies on daily torpor and heterothermy, including the ones in this issue, have furthered the field immensely. We look forward to a period of immense growth in this field.
Donors in lung transplantation: does age matter?
Authors: Ponte Charlotte , Alkhatiri Omar , Olland Anne , Falcoz Pierre-Emmanuel 
Published: July 2023

Summary
A best-evidence topic was written according to a structured protocol. The question addressed was the following: in patient undergoing lung transplantation, are lungs from donors of age &gt;60 years old (yo) associated with equivalent outcomes—including primary graft dysfunction, respiratory function and survival—than lungs from donors ≤60yo? Altogether, &gt;200 papers were found using the reported search, of which 12 represented the best evidence to answer the clinical question. The authors, journals, dates, country of publication, patients group studied, study type, relevant outcomes, and results of these papers were tabulated. Amongst the 12 papers reviewed, survival results were different depending on whether donor age was analysed raw or adjusted for recipients’ age and initial diagnosis. Indeed, recipients with interstitial lung disease (ILD), pulmonary hypertension or cystic fibrosis (CF) had significantly inferior overall survival when receiving grafts from older donors. When older grafts are allocated to younger donors, a significant decrease in survival has been noticed in the case of single lung transplantation. In addition, 3 papers showed worse results regarding peak forced expiratory volume in 1 second (FEV1) in patients receiving older organs, and 4 showed comparable primary graft dysfunction incidence rates. We conclude that when carefully assessed and allocated to the recipient who could benefit most from the transplant (e.g., a patient with a diagnosis of chronic obstructive pulmonary disease (COPD), who would not require a prolonged cardiopulmonary bypass (CPB)), lung grafts from donors of &gt;60yo offer comparable results to younger donors.
Left lower lobectomy without pericardial reconstruction in a patient with a congenital pericardium defect
Authors: Miura Jun , Ito Hiroyuki , Adachi Hiroyuki , Isaka Tetsuya 
Published: July 2023

Abstract
Pericardial defects are rare congenital disorders. We report a case of a left lower lobectomy in a patient with lung cancer, a congenital complete left-sided pericardial defect and severe pleural adhesions. The pleural adhesions between the epicardium and lungs were carefully dissected. A left lower lobectomy with mediastinal nodal dissection was performed under complete video-assisted thoracoscopic surgery without pericardial reconstruction. The patient remained asymptomatic for 20 months postoperatively. Careful dissection of severe adhesions is necessary in patients with severe cardiac pulsations.
Authoritarian Propaganda Campaigns on Foreign Affairs: Four Birds, One Stone, and the South China Sea Arbitration
Authors: Chubb Andrew , Wang Frances Yaping 
Published: July 2023

Abstract
Why do authoritarian states sometimes play up dangerous international crises and embarrassing diplomatic incidents in domestic propaganda? Is it to mobilize, threaten, divert, or pacify? Recent studies in comparative politics have focused on regime legitimacy and stability as key drivers of authoritarian propaganda practices, leaving aside other possible motivations such as mobilization of the regime’s domestic allies or strategic signaling aimed at foreign audiences. Foreign policy analysts, meanwhile, have emphasized international dimensions of the propaganda behavior of China—the contemporary world’s most powerful and technologically sophisticated authoritarian state—but have often mistakenly framed complementary theories as competing alternative explanations. This article argues that once the multiple domestic and international audiences for authoritarian propaganda are brought into view, many supposedly competing explanations turn out to be logically compatible and, in many cases, mutually reinforcing. We identify four sets of explanations—mobilization, signaling, diversion, and pacification—first showing how they fit together logically, before illustrating their convergence in the PRC’s otherwise puzzling high-intensity propaganda campaign in 2016 over the Philippines vs. China arbitration on the South China Sea.
Earning Structure and Heterogeneity of the Labor Market: Evidence from DR Congo
Authors: Ibale Douglas Amuli 
Published: July 2023

Abstract
Using 1.2.3 survey data on the Democratic Republic of Congo, we highlight different sectors in the labor market, with ‘higher paid’ sectors that are largely formal and ‘lower paid’ sectors that are largely informal. Based on a linear regression model, we report significant heterogeneity in earnings across sectors, which remain after controlling for aspects of human capital. We use a multinomial logit model to identify sector choice and show, allowing for selection, how returns to human capital differ across these sectors. We find that returns to basic education are important in largely informal sectors and that tertiary education is very important to access the higher paid sectors, but less important than in the lower paid sectors in increasing earnings once there. We then extend this analysis using quantile regression to show how returns differ across the distribution within sectors. Finally, we decompose the earnings gap across sectors and check how characteristics and return on these characteristics affect the cross-sector earnings gap. The earnings gap decomposition shows that workers of the lower paid sectors earn less, not only because they are less skill-endowed but also because they earn lower returns on their skills.
AnnoDash, a clinical terminology annotation dashboard
Authors: Xu Justin , Mazwi Mjaye , Johnson Alistair E W 
Published: July 2023

Abstract

Background
Standard ontologies are critical for interoperability and multisite analyses of health data. Nevertheless, mapping concepts to ontologies is often done with generic tools and is labor-intensive. Contextualizing candidate concepts within source data is also done in an ad hoc manner.

Methods and Results
We present AnnoDash, a flexible dashboard to support annotation of concepts with terms from a given ontology. Text-based similarity is used to identify likely matches, and large language models are used to improve ontology ranking. A convenient interface is provided to visualize observations associated with a concept, supporting the disambiguation of vague concept descriptions. Time-series plots contrast the concept with known clinical measurements. We evaluated the dashboard qualitatively against several ontologies (SNOMED CT, LOINC, etc.) by using MIMIC-IV measurements. The dashboard is web-based and step-by-step instructions for deployment are provided, simplifying usage for nontechnical audiences. The modular code structure enables users to extend upon components, including improving similarity scoring, constructing new plots, or configuring new ontologies.

Conclusion
AnnoDash, an improved clinical terminology annotation tool, can facilitate data harmonizing by promoting mapping of clinical data. AnnoDash is freely available at https://github.com/justin13601/AnnoDash (https://doi.org/10.5281/zenodo.8043943).

Abstract
Phenolic acid like with the 3-caffeoylquini acid (3-CQA) is formed by caffeic acid and qunic acid. This study was conducted to explore the effect of 3-CQA on growth performance and intestinal functions in weaned pigs. A total of 180 weaned pigs were randomly allocated into five treatments with 6 replicate pens per treatment (6 pigs per pen). Pigs in the control group (CON) were fed with basal diet (BD), and the others in the experimental groups were fed with BD and supplemented with 12.5, 25, 50, and 100 mg/kg 3-CQA. On day 43, the blood sample-collected pigs in the CON and optimal-dose group (only based on growth performance) were picked, and housed in metabolism cages (a total of 12 pigs, N = 6). 3-CQA increased the feed efficiency from days 21 to 42 of the trial and throughout the trial (P &lt; 0.05). 3-CQA increased the serum concentrations of total protein, albumin, and total cholesterol (P &lt; 0.05). Moreover, 3-CQA supplementation at 25 mg/kg increased the apparent digestibility of DM, energy, and ash (P &lt; 0.05). Interestingly, 3-CQA decreased the crypt depth but increased the ratio of villus height to crypt depth in the jejunum and ileum (P &lt; 0.05). Moreover, 3-CQA also increased the activities of sucrase, lactase, and catalase in the jejunal mucosa, and increased the activities of alkaline phosphatase and superoxide dismutase in the ileal mucosa (P &lt; 0.05). 3-CQA also increased the abundance of secretory immunoglobulin A in the ileal mucosa (P &lt; 0.05). Importantly, 3-CQA not only elevated the expression levels of critical functional genes such as the zonula occludens-1 , occludin, solute carrier family 7 , and nuclear factor erythroid 2-related factor 2 (Nrf2) in the duodenum but also elevated the expression levels of divalent metal transporter-1 and Nrf2 in the jejunum (P &lt; 0.05). These results suggested a positive effect of 3-CQA supplementation on the growth and intestinal functions of weaned pigs. The mechanisms of action may be associated with elevated anti-oxidant capacity and improved intestinal barrier functions.
Designing Educational and Home Computers in State Socialism: The Polish and Czechoslovak Experience
Authors: Wasiak Patryk , Švelch Jaroslav 
Published: July 2023

Abstract
This article investigates the design of two comparable microcomputers that were built under state socialism in neighboring countries: Poland (Elwro Junior) and Czechoslovakia (Didaktik Gama). Both computers were “clones” of the highly popular British ZX Spectrum computer. In our article, we discuss the decisions that informed the design of the local “clones” of the British computer, and how both endeavors were supposed to solve specific problems identified by the communities involved in their design. We argue that different configurations of power—in which the actors that took part in the design of both computers were embedded—were the primary reason why these similar products, the ZX Spectrum clones, were “scripted” in a substantially different manner. The Junior was designed as an “educational computer” envisaged as an aid to schooling, while the Gama was a more flexible “home computer.” Our investigation focuses on how their designers projected, or “scripted,” possible forms of computer use, and who they imagined would be the users of these machines. We also compare both computers with the high-profile One Laptop Per Child project to demonstrate the wider relevance of our study and the usefulness of our investigative toolset to the intersection of design studies and science and technology studies.
