51 Environmental hotspots analysis: A systematic framework for food supply chains and implementation case in the UK poultry industry
تجزیه و تحلیل کانون های محیطی: چارچوبی سیستماتیک برای زنجیره های تأمین مواد غذایی و موارد پیاده سازی در صنعت طیور انگلیس-2021
Environmental sustainability analyses of end-to-end food supply chain (SC) operations need to be per- formed regularly to accommodate reconfiguration opportunities arising in the global business landscape. This research scrutinises the pertinent literature and identifies the challenges of data availability, data obsolescence, computational complexity, and data specificity that associate to well-established environmental assessment methodologies, and proposes a stepwise approach that considers key players and processes for generating “close to real-time snapshots” of the main environmental hotspots for the focus firm. The applicability of the proposed systematic approach is demonstrated via an implementation at a resource-intensive sector of significant scale, i.e., the UK poultry industry. Overall, this research con- tributes to the SC environmental sustainability management domain by guiding the mapping and identification of environmental hotspots across end-to-end networks of operations in the form of a stepwise framework, and through articulating several research propositions.© 2021 Elsevier Ltd.

52 Nurses perspectives on pain management practices during newborn blood sampling in China
دیدگاه های پرستاران در مورد شیوه های مدیریت درد در طی نمونه گیری خون نوزادان در چین-2021
Introduction: Nurses’ use of evidence-based pain treatments for newborns during needle-related procedures in China was unknown. This study aimed to ascertain knowledge and use of pain management strategies and usefulness of a publicly accessible ’BSweet2Babies’ video, produced in Mandarin, demonstrating the use of breastfeeding, skin-to-skin care (SSC), and sweet solutions during painful procedures. Methods: An online survey was conducted during six nursing conferences in China ascertaining nurses’ previous viewing of the video and knowledge and use of the demonstrated strategies. Results: 221 nurses participated. Only 25 (11.3%) had previously seen the video. Over half knew that breast- feeding (n = 138, 62.4%) and SSC (n = 173, 78.3%) reduced pain, and 89 (40.3%) knew that sucrose reduced pain, but these strategies were infrequently used. Most intended to use the strategies in the future. Discussion: A knowledge-to-action gap for newborn pain management was identified. Future research is needed to improve the implementation of effective pain treatment for newborns.

53 Evaluation of six commercial SARS-CoV-2 rapid antigen tests in nasopharyngeal swabs: Better knowledge for better patient management?
ارزیابی شش تست آنتی ژن سریع SARS-COV-2 در سواب های نازوفارنکس: دانش بهتر برای مدیریت بهتر بیمار؟-2021
Robust antigen point-of-care SARS-CoV-2 tests have been proposed as an efficient tool to address the COVID-19 pandemic. This requirement was raised after acknowledging the constraints that are brought by molecular biology. However, worldwide markets have been flooded with cheap and potentially underperforming lateral flow assays. Herein we retrospectively compared the overall performance of five qualitative rapid antigen SARS- CoV-2 assays and one quantitative automated test on 239 clinical swabs. While the overall sensitivity and specificity are relatively similar for all tests, concordance with molecular based methods varies, ranging from 75,7% to 83,3% among evaluated tests. Sensitivity is greatly improved when considering patients with higher viral excretion (Ct≤33), proving that antigen tests accurately distinguish infectious patients from viral shedding. These results should be taken into consideration by clinicians involved in patient triage and management, as well as by national authorities in public health strategies and for mass campaign approaches.

54 Efficient biometric-based identity management on the Blockchain for smart industrial applications
مدیریت هویت مبتنی بر بیومتریک کارآمد در Blockchain برای کاربردهای صنعتی هوشمند-2021
In this work, we propose a new Blockchain-based Identity Management system for smart industry. First, we describe an efficient biometric-based anonymous credential scheme, which supports selective disclosure, suspension/thaw and revocation of credentials/entities. Our system provides non-transferability through a freshly computed hidden biometric attribute, which is generated using a secure fuzzy extractor during each authentication. This mechanism combined with offchain storage guarantees GDPR compliance, which is required for protecting user’s data. We define blinded (Brands) DLRep scheme to provide multi-show unlinkability, which is a lacking feature in Brands’ credential based systems. For larger organizations, we re-design the system by replacing the Merkle Tree with an accumulator to improve scalability. The new system enables auditing by adapting the standard Industrial IoT (IIoT) Identity Management Lifecycle to Blockchain. Finally, we show that the new proposal outperforms BASS, i.e. the most recent blockchain-based anonymous credential scheme designed for smart industry. The computational cost at the user-side (can be a weak IoT device) of our scheme is 8-times less than that of BASS. Thus, our system is more suitable for IIoT.© 2020 Elsevier B.V.

56 The politics behind scientific knowledge: Sustainable forest management in Latin America
سیاست پشت دانش علمی: مدیریت جنگل پایدار در آمریکای لاتین-2021
Sustainable Forest Management (SFM) seeks to achieve an equilibrium in the economic, social and environ- mental value of all types of forests. This practice contrasts with the conventional view of managing forests, in which the focus is productivity. Thus, discussions about conventional forest management versus sustainable forest management play a central role in the political and scientific agendas. However, knowledge production and its direction can be biased by different contextual factors such as the way funding is assigned by each country, institutional priorities, and constraints on international cooperation. With this paper, we aim to analyze the contribution of scientific knowledge produced in Latin America within the sustainable forest management research landscape by applying a literature review method (Scopus database for 2015–2018 period). Our results show a similar contribution of national and foreign funds and institutions supporting scientific knowledge about SFM in Latin America. Foreign funding comes mainly from United States of America, and Europe. Latin American authors lead high proportion of scientific articles, and authorship gender was more equitable between male and female researchers. The studies were mostly focused on conservation combined with productivity goals, as well as pure conservation goals, although social studies and restoration goals were also present. Our findings highlight a significant contribution to the paradigm shift in half of the scientific articles. Some studies provided recom- mendations (specific or general) derived from their results, but we did not detected a clear relationship with funding origin. Moreover, we found that the high contribution to the paradigm shift (studies supporting SFM instead of traditional management) came from institutions based in Latin America. This article aims to contribute to discussions related to scientific funding in Latin America, the North-South scientific relations, and the future of forest in times of climate change.

57 Effect of a theory-driven educational intervention on the level of knowledge, attitudes, and assessment practices regarding breakthrough cancer pain (BTCP) management among medical nurses in Hong Kong
تأثیر مداخله آموزشی مبتنی بر تئوری بر سطح دانش، نگرش ها و شیوه های ارزیابی در مورد مدیریت سرطان پیشرفته (BTCP) در پرستاران پزشکی در هنگ کنگ-2021
Purpose: To examine the effect of an educational intervention intended to improve medical nurses’ adherence to breakthrough cancer pain (BTCP) assessment practices and their level of knowledge, attitudes and perceived assessment practices regarding BTCP management. Methods: Nurses working in a regional hospital were recruited to this quasi-experimental study. The intervention group received a 3-h educational workshop and one session of individual clinical instruction, whilst the control group did not receive any intervention. Chart audits were performed to examine adherence to BTCP assessment practices as the primary outcome. A self-developed questionnaire was used to measure nurses’ knowledge, at- titudes and perceived assessment practices regarding BTCP management as the secondary outcomes. The chi- square or Fisher’s exact test was used to compare the rate of adherence to BTCP assessment practices between groups. A generalised estimating equation was used to compare changes in knowledge, attitudes, and perceived assessment practices between groups over time. Results: One hundred and five nurses completed the study. The chart audits revealed a significantly higher rate of adherence to BTCP assessment practices in the intervention group after the intervention (p < .05). The inter- vention group exhibited significant positive changes in scores for knowledge (β = 25.49, p < .001), attitude (β = 0.98 to 2.81, p < .01), and their perceived assessment practices (β = 1.33 to 3.14, p < .002) when compared with the control group. Conclusions: This theory-driven educational intervention significantly improved the medical nurses’ adherence to BTCP assessment practices and their level of knowledge attitudes and perceived assessment practices regarding BTCP management.

58 Sustainability at stake during COVID-19: Exploring the role of accounting in addressing environmental crises
پایداری در معرض خطر در Covid-19: بررسی نقش حسابداری در رسیدگی به بحران های زیست محیطی-2021
In this paper, we reflect and provide insights on the environmental implications of postCOVID-19 economic recoveries. More specifically, we highlight the connection(s) between the environment and the COVID-19 crisis, in particular the intertwined links between Mother Nature and the virus. We then raise some concerns about the ‘illusionary’ positive and negative effects of the crisis on the environment before evoking some past lessons about crisis management and recovery. We contend that the current accounting and accountability mechanisms employed in economic stimulus programs, as well as traditional environmental accounting approaches, are inadequate and limiting to achieve long-term sustainability change. The paper concludes by offering accounting practitioners and researchers some possibilities to take a step forward and develop new understandings of social and environmental value consistent with ecological principles and sustainable development—and hope that these reflections will contribute to a broader debate on the role of accounting for sustainable development in the Anthropocene

59 The effects of personal information management capabilities and social-psychological factors on accounting professionals’ knowledge-sharing intentions: Pre and post COVID-19
تأثیر قابلیت های مدیریت اطلاعات شخصی و عوامل اجتماعی-روانشناختی بر اهداف به اشتراک گذاری دانش حرفه ای حسابداری: پیش و پست Covid-19-2021
Given the increased emphasis on individual factors in knowledge management research, this study proposes a research model that examines the effects of personal information management capabilities and social-psychological factors on the knowledge-sharing intention of accounting professionals. The survey results from 136 accounting professionals reveal that both personal information management capabilities and perceived image can positively influence knowledge- sharing behavior. Conversely, reciprocity and loss of knowledge power do not exhibit a signifi- cant role in knowledge-sharing intentions. The comparison analyses between pre- and post- COVID-19 sample groups indicate similar results for the hypothesized relationships while there are notable mean differences in knowledge sharing intention, image and information processing capabilities. This study extends current research by incorporating personal information man- agement capabilities to examine the power of the “individual” in knowledge sharing and offers timely evidence of accounting professionals’ personal knowledge management practices during the period of COVID-19. This study raises implications for researchers and practitioners interested in knowledge management in the accounting profession.

60 Green supply chain management and clean technology innovation: An empirical analysis of multinational enterprises in China
مدیریت زنجیره تامین سبز و نوآوری در فناوری پاک: تجزیه و تحلیل تجربی شرکت های چند ملیتی در چین-2021
This study identifies the impact of green supply chain management (GSCM) on clean technology innovation (CTI) by enterprises in China as well as compares the effects of forward and backward GSCM and the differences by industry and home country. The effect of CTI on GSCM is tested by 501 samples of mostly multinational enterprises in China from 2014 to 2016. The results indicate that CTI benefits from GSCM, which remains robust to a series of sensitivity test. And different management directions show great differences, where the backward GSCM has a stronger promotion effect on CTI than the forward GSCM. Moreover, light polluting industries and capital-intensive industries have stronger incentives to adopt GSCM than heavy-polluting industries and labour intensive industries. And domestic companies perform better than foreign companies.
