مما لابد فيه ان يبتدئ الباحث بمفاتيح البحث ويعرفها ويوضح مقاصدها بغية الولوج في البحث لا سيما يورد حديث الدارسين قدماء ومحدثين عما يطلق عليه "التعجب" بعضها اتجاه مطلق لا تحديد له ولا ضوابط، واخر "اصطلاحي" أو "قياسي" مضبوط بضوابط وقواعد محددة كما سنرى.

التعجب لغة: من عجب، والعجب هو إنكار ما يود اعتياده وجمع العجب اعجاب (لسان العرب: مادة (عجب)).

اما اصطلاحاً: "استعظام زيادة في وصف الفاعل خفي سببها، وخرج بها المتعجب منه عن نظائره او قل نظيره"( المقرب (ابن عصفور) ص76). وبه فهو انفعال النفس عند شعورها بما خفي سببه (ينظر: شذا العرف في فن الصرف ص91)
وملخص القول اللغوي التعجب: تـَفُعُّل من العجب وله الفاظ كثيرة غير مُبٌوب لها في النحو كقوله تعالى (كيفً تكفرونً باللهِ) {البقرة (28)} وقوله عليه الصلاة والسلام "سبحان الله المئ المؤمن لا ينجُسُ حَياً ولا ميَتاً" وقولهم لله َدَرُّه فارسا( ينظر: شرح قطر الندى وبل الصدى (ابن هشام الانصاري) ص320) وقيل هو شعور داخلي تنفعل به النفس وقد تكون للشعور الداخلي إثاره الخارجية كالتي تظهر على الوجه او غير ذلك ولهذا يقال إذا ظهر السبب بَطُلَ العجب، ولهذا لا يوصف الله تعالى بانه متعجب اذ يخفى عليه شيء، واذا ظهر التعجب في قوله تعالى أو الحديث الشريف ما ظاهره انه للتعجب فيكون المراد منه اما توجيه المراد الى العجب والدهشة، واما الى الرضا والتسليم (النحو الوافي 3/339). مثاله قوله تعالى: (فما اصبرهم على النار) أي ان حالهم يستدعي أنْ يتعجب منه أو الحديث الشريف: (عجب ربنا من قوم يغادرون الى الجنة في سلاسل) وهؤلاء هم أسرى المشركين يسلمون فيدخلون الجنة. والقياس في عدم التعجب من صفاته تعالى التي لا تقبل الزيادة نحو: ما اعظمه وما اقدره، وما اعلمه وقد اجاز ذلك العلماء بقصد الثناء عليه سبحانه وتعالى اي انه في غاية العظمة مما تحار فيه العقول (ينظر: اوضح المسالك في شرح الفية ابن مالك 3/231).

AbstractBiomass is the sole carbon‐containing renewable resource on Earth, and has high potential for the production of platform chemicals. Phenol, one of the most important platform chemicals, is generally derived from lignin conversion. In this study, the production of phenol from co‐pyrolysis of cellulose and sodium borohydride at different mass ratios is investigated in detail. The results show that even a small amount of sodium borohydride (cellulose–sodium borohydride = 10:1) could effectively promote the conversion of cellulose to phenol through cellulose‐derived levoglucosan intermediates. As the mass ratio of cellulose–sodium borohydride decreased, the relative content of phenol in the products significantly increased, and could be as high as 11.0% when the ratio of cellulose to sodium borohydride was 2:1. Glycosidic bonds in cellulose were considered to play an important role in its catalytic conversion. Furthermore, the resulting solid product could be used as a B‐doping carbon material, which is desirable in various research fields. This study provided a novel method for the highly efficient utilization of cellulose. © 2022 Society of Chemical Industry and John Wiley & Sons, Ltd.

AbstractStructural stigma shapes men who have sex with men’s (MSM’s) mental health and sexual behaviours. The aim of this study was to examine how stigmatizing policies interact with downstream anxiety/depression and sexual behaviours to structurally pattern HIV disparities among European MSM. We conducted a secondary data analysis of the European Men-who-have-sex-with-men Internet Survey (EMIS) from 2017. We included a total of 98,600 participants living in 39 European countries. We used the Rainbow Index, a score given to countries based on their sexual and gender minority policies as the predictor of HIV diagnosis. We conducted adjusted random intercept and slope multi-level logistic regressions. In adjusted models, higher Rainbow Index scores was associated with lower predictive probabilities of diagnosed HIV, regardless of the number of condomless intercourse partners. The predictive probability of HIV diagnosis was also lower, regardless of severity of anxiety/depression, where the Rainbow Index score was better. Country-level policies interact with downstream sexual behaviours and anxiety/depression to structurally influence HIV diagnosis among MSM in Europe.
Reviewing Paradox Theory in Corporate Sustainability Toward a Systems Perspective
Authors: Carmine Simone , De Marchi Valentina 
Published: April 2022

AbstractThe complexity of current social and environmental grand challenges generates many conflicts and tensions at the individual, organization and/or systems levels. Paradox theory has emerged as a promising way to approach such a complexity of corporate sustainability going beyond the instrumental business-case perspective and achieving superior sustainability performance. However, the fuzziness in the empirical use of the concept of “paradox” and the absence of a systems perspective limits its potential. In this paper, we perform a systematic review and content analysis of the empirical literature related to paradox and sustainability, offering a useful guide for researchers who intend to adopt the concept of “paradox” empirically. Our analysis provides a comprehensive account of the uses of the construct - which allows the categorization of the literature into three distinct research streams: 1) paradoxical tensions, 2) paradoxical frame/thinking, and 3) paradoxical actions/strategies - and a comprehensive overview of the findings that emerge in each of the three. Further, by adopting a system perspective, we propose a theoretical framework that considers possible interconnections across the identified paradoxical meanings and different levels of analysis (individual, organizational, systems) and discuss key research gaps emerging. Finally, we reflect on the role a clear notion of paradox can have in supporting business ethics scholars in developing a more “immanent” evaluation of corporate sustainability, overcoming the current instrumental view.
A model of checkpoint behavior for applications that have I/O

Published: April 2022

AbstractDue to the increase and complexity of computer systems, reducing the overhead of fault tolerance techniques has become important in recent years. One technique in fault tolerance is checkpointing, which saves a snapshot with the information that has been computed up to a specific moment, suspending the execution of the application, consuming I/O resources and network bandwidth. Characterizing the files that are generated when performing the checkpoint of a parallel application is useful to determine the resources consumed and their impact on the I/O system. It is also important to characterize the application that performs checkpoints, and one of these characteristics is whether the application does I/O. In this paper, we present a model of checkpoint behavior for parallel applications that performs I/O; this depends on the application and on other factors such as the number of processes, the mapping of processes and the type of I/O used. These characteristics will also influence scalability, the resources consumed and their impact on the IO system. Our model describes the behavior of the checkpoint size based on the characteristics of the system and the type (or model) of I/O used, such as the number I/O aggregator processes, the buffering size utilized by the two-phase I/O optimization technique and components of collective file I/O operations. The BT benchmark and FLASH I/O are analyzed under different configurations of aggregator processes and buffer size to explain our approach. The model can be useful when selecting what type of checkpoint configuration is more appropriate according to the applications’ characteristics and resources available. Thus, the user will be able to know how much storage space the checkpoint consumes and how much the application consumes, in order to establish policies that help improve the distribution of resources.
Detection of the Type of Left and Right Returns-to-Scales Using Envelopment DEA Models in Crisp and Fuzzy Environments: An Application for Predicting Changes in the Stock Market
Authors: Payan Ali , Hajihosseini Alireza , Nosrat Azizollah 
Published: April 2022

AbstractThis paper aims to analyze left and right returns-to-scales in crisp and fuzzy data envelopment analysis (DEA). Since all previous envelopment DEA models for assessing left and right returns-to-scales are parametric, they are prone to encountering infeasibility problems, producing incorrect or different solutions for determining the type of returns-to-scale because of the different choices of parameter values. This misdiagnosis will lead to poor management decisions. Due to the mentioned problems, the issue of one-sided returns-to-scale has also not been studied in inaccurate environments. The present paper first proposes an alternative method of left and right returns-to-scales determination with crisp data to address this problem. This approach develops two non-parametric envelopment DEA models for analyzing left and right returns-to-scales. Then, the proposed method is extended to the fuzzy environment where data are considered more realistic. Due to its major advantages, credibility measure is used for solving fuzzy DEA models built to determine left and right returns-to-scales. As an application of the proposed method, data of companies in the Iran stock market are collected for 2014–2019 as fuzzy data and frontier units are analyzed by one-sided returns-to-scale.

Published: April 2022

AbstractFault attacks have been proved for efficiently breaking hardware‐based elliptic curve cryptosystems. One way for fighting against fault attacks is to design the core multiplier circuit of elliptic curve cryptosystem with concurrent error detection capability. The multiplier with concurrent error detection only outputs its results if no existing error is found. This paper will design a systolic array Dickson basis multiplier with concurrent error detection capability for resisting fault attacks on elliptic curve cryptosystems.
Bright γ-ray source with large orbital angular momentum from the laser near-critical-plasma interaction
Authors: BAKE Mamat Ali , TANG Suo , XIE Baisong 
Published: April 2022

Abstract
We propose a new laser-plasma-based method to generate bright γ-rays carrying large orbital angular momentum by interacting a circularly polarized Laguerre–Gaussian laser pulse with a near-critical hydrogen plasma confined in an over-dense solid tube. In the first stage of the interaction, it is found via fully relativistic three-dimensional particle-in-cell simulations that high-energy helical electron beams with large orbital angular momentum are generated. In the second stage, this electron beam interacts with the laser pulse reflected from the plasma disc behind the solid tube, and helical γ beams are generated with the same topological structure as the electron beams. The results show that the electrons receive angular momentum from the drive laser, which can be further transferred to the γ photons during the interaction. The γ beam orbital angular momentum is strongly dependent on the laser topological charge l and laser intensity a

. A short (duration of 5 fs) isolated helical γ beam with an angular momentum of −3.3 × 10−14 kg m2 s−1 is generated using the Laguerre–Gaussian laser pulse with l = 2. The peak brightness of the helical γ beam reaches 1.22 × 1024 photons s−1 mm−2 mrad−2 per 0.1% BW (at 10 MeV), and the laser-to-γ-ray angular momentum conversion rate is approximately 2.1%.
Biological soil crusts and how they might colonize other worlds: insights from these Brazilian ecosystem engineers
Authors: Oliveira Mateus Fernandes , Maciel-Silva Adaíses Simone 
Published: April 2022

Abstract
When bryophytes, lichens, eukaryotic algae, cyanobacteria, bacteria, and fungi live interacting intimately with the most superficial particles of the soil, they form a complex community of organisms called the biological soil crust (BSC or biocrust). These biocrusts occur predominantly in drylands, where they provide important ecological services such as soil aggregation, moisture retention, and nitrogen fixation. Unfortunately, many BSC communities remain poorly explored, especially in the tropics. This review summarizes studies about BSCs in Brazil, a tropical megadiverse country, and shows the importance of ecological, physiological, and taxonomic knowledge of biocrusts. We also compare Brazilian BSC communities with others around the world, describe why BSCs can be considered ecosystem engineers, and propose their use in the colonization of other worlds.
Feedback of Individual Genetic and Genomics Research Results: A Qualitative Study Involving Grassroots Communities in Uganda

Published: April 2022

AbstractBackgroundGenetics and genomics research (GGR) is associated with several challenges including, but not limited to, implications of sharing research findings with participants and their family members, issues of confidentiality, determining appropriate methods for providing genetic or genomic information to individuals tested, and ownership of DNA obtained from the samples. Additionally, GGR holds significant potential risk for social and psychological harms.A considerable amount of research has been conducted with resultant literature and global debate on return of genetic and genomics testing results, but such investigations are limited in the African setting, including Uganda.The objective of the study was to assess perceptions of grassroots communities on if and how feedback of individual genetics and genomics testing results should be carried out in a Ugandan setting.MethodsThis was a cross-sectional study that employed a qualitative exploratory approach. A total of 42 individuals from grassroots communities representing three major ethnic groupings participated in five deliberative focus group discussions. Data were analysed through content analysis along the main themes of the study. NVivo software (QSR international 2020) was used to support data analysis and illustrative quotes were extracted.ResultsOf the 42 respondents 23 (55%) were male with an age range of 18-77 years. Most (70%) were small scale farmers, and the majority were Christians, who were married and had children. They all lived in a rural community in one of the three regions of the country and had no prior participation in GGR. All the respondents were willing to undergo genetics testing and receive feedback of results with the main motivation being diagnostic and therapeutic benefits as well as facilitating future health planning. Content analysis identified three themes and several sub-themes including 1) the need to know one’ s health status; 2) ethical considerations for feedback of findings and 3) extending feedback of genetics findings to family and communityConclusionParticipation in hypothetical genetics and genomics research as well as feedback of testing results is acceptable to individuals in grassroots communities. The strong therapeutic misconception linked to GGR is concerning and has implications for consent processes and genetic counselling. Privacy and confidentiality, benefits, risks as well as implications for sharing need to be considered for such feedback of results to be conducted appropriately.
