1 Semantic Riverscapes: Perception and evaluation of linear landscapes from oblique imagery using computer vision
مناظر معنایی رودخانه: درک و ارزیابی مناظر خطی از تصاویر مایل با استفاده از بینایی کامپیوتری-2022
Traditional approaches for visual perception and evaluation of river landscapes adopt on-site surveys or as- sessments through photographs. The former is expensive, hindering large-scale analyses, and it is conducted only on street-level or top-down imagery. The latter only reflects the subjective perception and also entails a laborious process. Addressing these challenges, this study proposes an alternative: a novel workflow for visual analysis of urban river landscapes by combining unmanned aerial vehicle (UAV) oblique photography with computer vision (CV) and virtual reality (VR). The approach is demonstrated with an experiment on a section of the Grand Canal in China where UAV oblique panoramic imagery has been processed using semantic segmentation for visual evaluation with an index system we designed. Concurrent surveys, immersive and non-immersive VR, are used to evaluate these photos, with a total of 111 participants expressing their perceptions across multiple dimensions. Then, the relationship between the people’s subjective visual perception and the river landscape environment as seen by computers has been established. The results suggest that using this approach, rivers and surrounding landscapes can be analyzed automatically and efficiently, and the mean pixel accuracy (MPA) of the developed model is 90%, which advances state of the art. The results of this study can benefit urban planners in formulating riverside development policies, analyzing the perception of plans for a future scenario before an area is rede- veloped, and the method can also aid relevant parties in having a macro understanding of the overall situation of the river as a basis for follow-up research. Due to simplicity, accuracy and effectiveness, this workflow is transferable and cost-effective for large-scale investigations of riverscapes and linear heritage. We openly release Semantic Riverscapes—the dataset we collected and processed, bridging another gap in the field.

3 A survey on security in internet of things with a focus on the impact of emerging technologies
بررسی امنیت در اینترنت اشیا با تمرکز بر تاثیر فناوری های نوظهور-2022
Internet of Things (IoT) have opened the door to a world of unlimited possibilities for imple- mentations in varied sectors in society, but it also has many challenges. One of those challenges is security and privacy. IoT devices are more susceptible to security threats and attacks. Due to constraints of the IoT devices such as area, power, memory, etc., there is a lack of security so- lutions that are compatible with IoT devices and applications, which is leading this world of securely connected things to the “internet of insecure things.” A promising solution to this problem is going beyond the standard or classical techniques to implementing the security so- lutions in the hardware of the IoT device. The integration of emerging technologies in IoT net- works, such as machine learning, blockchain, fog/edge/cloud computing, and quantum computing have added more vulnerable points in the network. This paper introduces a comprehensive study on IoT security threats and solutions. Additionally, this survey outlines how emerging technologies such as machine learning and blockchain are integrated in IoT, challenges resulted from this integration, and potential solutions to these challenges. The paper utilizes the 4-layer IoT architecture as a reference to identify security issues with corresponding solutions.

4 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.

5 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.

6 ‘Going agile’: Exploring the use of project management tools in fostering psychological safety in group work within management discipline courses
رفتن چابک: بررسی استفاده از ابزارهای مدیریت پروژه در پرورش ایمنی روانشناختی در کار گروهی در دوره های انضباط مدیریت-2021
While psychological safety is widely acknowledged to be a crucial factor in determining how well teams function, little attention has been paid to this phenomenon in management education and HE more broadly. This highlights an important gap, given the ‘thorny’ nature, and pervasive use, of group work. We contribute the first examination of an HE intervention to increase psycho- logical safety. Specifically, through a two-phase mixed methods approach (pre/post surveys and focus groups, student diaries), we examine the implementation of Agile project management principles in both an undergraduate and postgraduate digital marketing course (total n = 131). The findings illustrate that the intervention increased psychological safety along with team- performance, group learning, interpersonal communication and creativity, whilst also reducing the free-rider problem. The study provides three contributions. First, we extend knowledge of psychological safety by showing it can be fostered through interventions providing two core antecedents (supporting facilitation and a cohesive framework). Second, we build knowledge of psychological safety in education by evidencing a greater breadth of positive outcomes, which until now has been mostly limited to knowledge development. Third, we expand understanding of implementing group work interventions in management, providing five important considerations for educational practitioners.

7 Linking standard Economic Account for Forestry and ecosystem accounting: Total forest incomes and environmental assets in publicly-owned conifer farms in Andalusia-Spain
پیوند حساب استاندارد اقتصادی برای حسابداری جنگلداری و اکوسیستم: کل درآمد جنگل ها و دارایی های محیطی در مزارع عمومی متعلق به مالکیت در اندلس اسپانیا-2021
A major problem faced by government as trustee of society charged with conserving the nation’s forest envi- ronmental asset is that the standard Economic Account for Forestry (EAF) fails to measure the contribution of nature to total forest incomes and environmental assets. In the context of this government mission, the debate arises with regard to how to uncover the contribution of nature to the total forest incomes enjoyed by people through a refined accounting framework which extends the EAF. The latter is applied by the statistics office to estimate the values added of timber, firewood, cork, resin, industrial nut and other non-woody final products of the forest at national/sub-national scale. Bearing in mind this narrow scope of the EAF, this research proposes the application of the experimental Agroforestry Accounting System (AAS), which extends the forest incomes and environmental asset estimates by applying simulated exchange values stated/revealed by consumers for non- market public goods and services. We apply the EAF and AAS frameworks to 12 large publicly-owned pro- tected conifer forest farms which are not available for sale on the competitive land market and which cover an area of 47,262 ha in Andalusia-Spain. In this conifer farm case study, the EAF considers the economic activities of timber, firewood, aromatic plants and residential service. The AAS adds to the EAF activities those of grazing, conservation forestry, hunting, livestock, agricultural crops, livestock-keeper private amenity, fire services, free access recreation, mushrooms, carbon, landscape conservation, threatened wild biodiversity and water supply runoff stored lower down the watershed in public reservoirs. The objectives of this conifer farm case study are, first, to compare the final products and incomes estimated by applying the EAF and AAS frameworks and, second, to measure the sensitivity of conifer farm environmental assets to changes in land ownership rights and dis- counting rates in accordance with the AAS results. The conifer farm results show total income measured by the AAS is 38 times higher than the EAF net value added (NVA) for the 2010 period. The AAS economic activities of forestry conservation, fire services and landscape conservation activities generate 71% of the conifer farm labour compensation. The AAS opening environmental asset measured at the assumed competitive real baseline dis- counting rate of 3% is 6371.6 €/ha, which is 3.7 times lower than it would be if the conifer farm was available for sale on the competitive land market. The change in the baseline discounting rate chosen, from 3% to 1.5%, would lead to an increase of 116% in the value of the opening environmental asset. The above results reveal the inconsistent EAF measurement of total conifer farm incomes. The sensitivity analysis underlines the important effects on the environmental asset arising from changes in land ownership rights and discounting rates.

9 An examination of customer relationship management dimensions and employee-based brand equity: A study on ride-hailing industry in Saudi Arabia
بررسی ابعاد مدیریت ارتباط با مشتری و سهام برند مبتنی بر کارکنان: مطالعه در مورد صنعت سواری در عربستان سعودی-2021
The purpose of this study was to explore the effect of customer relationship management (CRM) dimensions on employee-based brand equity. By looking at the past literature, it can be noticed that the majority of earlier studies on brand equity examined it from customers perspective, while the employees perspective received less emphasis. Thus, the required data was obtained using a survey tool from 164 employees in the ride-hailing industry in Saudi Arabia. The obtained data was analyzed by the Covariance-Based Structural Equation Modeling (CB-SEM) method to test the hypothesis and reach at conclusions. The findings showed that CRM in general has a positive effect on employee-based brand equity. Specifically, it was found that CRM organization has a significant positive impact on employee-based brand equity. It was also verified that knowledge man- agement and customer orientation have positive effects on overall employee-based brand equity. Finally, the results confirmed that technology-based CRM has a significant positive impact on employee-based brand equity. These results add to the body of literature on this topic and verify the significance of customer relationship management dimensions in affecting employee-based brand equity.

10 Learning from past earthquake disasters: The need for knowledge management system to enhance infrastructure resilience in Indonesia
یادگیری از بلایای زلزله گذشته: نیاز به سیستم مدیریت دانش برای افزایش انعطاف پذیری زیرساخت در اندونزی-2021
Indonesia lies at the region where Indo-Australian, Eurasian, Pacific and Philippines global tectonic plates meet. In the last 30 years, Indonesia has experienced catastrophic earthquake disasters, causing thousands of loss of life and major infrastructure damage. Since the 2004 devastating Sumatra-Andaman tsunamigenic earthquake, knowledge derived from various disaster experiences regarding infrastructure resilience have been improving. Yet disasters such as the recent 2018 Lombok and Palu earthquakes remain devastating. An investigation on how knowledge on past earthquakes have been managed and utilized to promote better resilient infrastructure in Indonesia is conducted. Lessons are extracted from 5 significant earthquakes causing major damage through compilation and analysis of scientific publications and reports on field surveys, works and existing policies. Factors that keep contributing to the failure of buildings and infrastructure include lack of understanding of local hazard situation, incompliance to seismic resistant codes and standards for buildings and infrastructure, prob- lematic soil condition, and collateral hazards such as tsunami, liquefaction, ground subsidence, landslides, rock avalanche which are adding to the complexity of the seismic hazard. The scarcity of information and knowledge on the performance on resilience of infrastructure during earthquakes in Indonesia limits knowledge-based de- cision making in the planning, development and operation of resilient infrastructure. This study calls for the development of a knowledge management system for earthquake resilient infrastructure in Indonesia, to save more lives and to reduce economic disruptions due to infrastructure damages, and thus contribute to the sus- tainable development goals achievement.
