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. keywords: ریورساید | باز کردن داده ها | GeoAI | بررسی های هوایی | هواپیماهای بدون سرنشین | واقعیت مجازی | Riverside | Open data | GeoAI | Aerial surveys | Drones | Virtual reality |

Resource Allocation in Time Slotted Channel Hopping (TSCH) Networks Based on Phasic Policy Gradient Reinforcement Learning
تخصیص منابع در شبکه های گام کانال با شکاف زمانی (TSCH) بر اساس یادگیری تقویت گرادیان خط مشی فازی-2022 The concept of the Industrial Internet of Things (IIoT) is gaining prominence due to its lowcost solutions and improved productivity of manufacturing processes. To address the ultra-high
reliability and ultra-low power communication requirements of IIoT networks, Time Slotted
Channel Hopping (TSCH) behavioral mode has been introduced in IEEE 802.15.4e standard.
Scheduling the packet transmissions in IIoT networks is a difficult task owing to the limited
resources and dynamic topology. In IEEE 802.15.4e TSCH, the design of the schedule is open
to implementation. In this paper, we propose a phasic policy gradient (PPG) based TSCH
schedule learning algorithm. We construct the utility function that accounts for the throughput,
and energy efficiency of the TSCH network. The proposed PPG based scheduling algorithm
overcomes the drawbacks of totally distributed and totally centralized deep reinforcement
learning-based scheduling algorithms by employing the actor–critic policy gradient method that
learns the scheduling algorithm in two phases, namely policy phase and auxiliary phase. In
this method, we show that the schedule converges quickly compared to any other actor–critic
method and also improves the system throughput performance by 58% compared to the minimal
scheduling function, a default TSCH schedule.

Assessing the Needs of the Quantum Industry
ارزیابی نیازهای صنعت کوانتومی-2022 Background: Quantum information science and
technology (QIST) has progressed significantly in the last decade,
such that it is no longer solely in the domain of research labs,
but is now beginning to be developed for, and applied in, industrial applications and products. With the emergence of this new
quantum industry, a new workforce trained in QIST skills and
knowledge is needed.
Research Questions: To help support the education and training of this workforce, universities and colleges require knowledge
of the type of jobs available for their students and what skills
and degrees are most relevant for those new jobs. What are these
jobs, skills, and degrees?
Methodology: We report on the results from a survey of 57
companies in the quantum industry, with the goal of elucidating the jobs, skills, and degrees that are relevant for this new
workforce.
Findings: We find a range of job opportunities from highly
specific jobs, such as quantum algorithm developer and error
correction scientist, to broader jobs categories within the business, software, and hardware sectors. These broader jobs require
a range of skills, most of which are not quantum related.
Furthermore, except for the highly specific jobs, companies that
responded to the survey are looking for a range of degree levels
to fill these new positions, from bachelors to masters to Ph.D.s.
Contribution: With this knowledge, students, instructors, and
university administrators can make informed decisions about
how to address the challenge of increasing the future quantum
workforce.

Fog Node Self-Control Middleware: Enhancing context awareness towards autonomous decision making in Fog Colonies
میان افزار خودکنترلی گره مه: افزایش آگاهی از زمینه به سمت تصمیم گیری مستقل در کلونی های مه-2022 The concept of Fog Colonies has recently been introduced in Fog Computing, and is rapidly
gaining attention. As Fog Colonies are extended, Fog Colony Control mechanisms have gained
significant interest. Although, there are numerous solutions efficiently supporting a Context
Aware coordinating entity, exploring approaches for decentralized control remains a challenge.
Towards this direction, there are efforts promoting the concept of autonomous Fog Nodes,
making their own decisions with internalized control without the existence of a coordinating
entity. In this paper we propose and implement a Context Aware Self-Control management
middleware for Fog Nodes, enabling their Self-Management utilizing contextual information
shared between Fog colony members. To that end, we employ Policy Rulebooks to define
Context Aware Policies that each Fog Node can enforce. Finally, we evaluated the proposed
middleware against a non Context Aware one, under exactly the same conditions, using a
real-world smart building use case, focusing on performance issues related to the end-user.

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. keywords: سیاست های جنگلداری | همکاری بین المللی | بررسی ادبیات | منابع طبیعی | تحقیق و توسعه | بودجه پژوهشی | Forestry policies | International cooperation | Literature review | Natural resources | Research and development | Research funding |

The architecture of accounting and the neoliberal betrayal of life
معماری حسابداری و خیانت نئولیبرالی از زندگی-2021 This paper identifies the way in which accounting practices reinforced the increasing influence of
the intolerant financial emphasis of the market on the quality of social housing under neoliber-
alism when successive British governments gave little importance to the impact of aesthetic and
ethical qualities of social housing on the well-being of inhabitants. Social values, most especially
safety and beauty, were able to be reinterpreted according to economic logic, thereby denying the
need for them to be explicitly considered in any social housing decisions. The study emphasises
the way in which the austerity and deregulation agenda of neoliberal policies that had a signif-
icant impact on building and fire safety regulations were ultimately justified by financial criteria.
The Grenfell Tower fire in 2017 belatedly exposed the way in which the financial and operational
visibilities created by accounting practices had become crucial to the successful implementation
of the economic logic of the neoliberal agenda and related market priorities of successive British
governments, irrespective of the consequences. The paper demonstrates how the Grenfell Tower
refurbishment was the apotheosis of neoliberalism; a toxic mix of austerity, outsourcing and
deregulation. The focus on value for money in the refurbishment led ultimately to the betrayal of
life of the residents. keywords: حسابداری | برج گرنفل | مسکن اجتماعی | نئولیبرالیسم | فوکو | Accounting | Grenfell Tower | Social housing | Neoliberalism | Foucault |

Framing accounting for goodwill: Intractable controversies between users and standard setters
فریم کردن حسابداری برای حسن نیت: اختلافات قابل انعطاف بین کاربران و برنامه های استاندارد-2021 How to account for goodwill arising from business combinations has proven to be one the most
controversial topics for the standardisation, preparation, and audit of financial reports. Given its
contested nature, and recent debates about improper goodwill accounting by failing companies,
standard setters are currently reconsidering existing recognition, measurement, and disclosure
requirements. In this study, we explore the views of a relatively neglected group of stakeholders
in the financial reporting policy-making arena – financial statement users. We draw on empirical
evidence from interviews with financial analysts and from responses by analysts to IASB and
EFRAG consultations. We mobilise framing theory as used in public policy studies to analyse how
users make sense of goodwill accounting information as compared to standard setters. Our key
finding is the plurality of colliding frames between users and standard setters that remain
intractable. Our analysis reveals that users’ interest in management’s accountability on acquisi-
tions cannot fit easily into the financial reporting frame. Not only are claims by standard setters
about the value relevance of goodwill impairments found not to be experienced in practice, but
also we discover that users question the benefits of standard setters working in this area, while
they take recourse to ‘street numbers’ for their analysis. We interpret the intractability we
discover as putting into question public policy claims that accounting policies are developed with
a commitment to serve the public interest. keywords: IFRS | حسن نیت | آنالیز مالی | کادر بندی | IFRS | Goodwill | Financial analysis | Framing |

Intellectual engagements of accounting academics: The ‘forecasted losses intervention
تعاملات ذهنی دانشگاهی حسابداری: مداخله زیان پیش بینی شده-2021 This paper explores the social and political potential of accounting scholarship, presenting and
discussing an intellectual intervention challenging a legislative reform that significantly affected
Spanish industrial relations. In this reform, an accounting artifact (forecasted losses) played an
unexpected role and was misrepresented, prompting a sizeable number of scholars to sign two
manifestos in 2010 and 2012 against the use of forecasted losses made by the new legislation. As
promoters of this manifesto, we perform in this paper a collaborative autoethnography to reflect
on the context, events, reactions, and significance of this intervention for both the academic and
the industrial relations fields. We mobilize Pierre Bourdieu’s ideas on the public intellectual to
think more generally about academic engagements in the interplay between accounting, poli-
cymaking, and social issues. This intervention illustrates the different manners in which admin-
istrative and economic powers interfered in the Spanish accounting academic field, limiting the
disposition of Spanish scholars to engage in public debates. We also interpret our engagement as
mobilizing intellectual capital to expose how the notion of forecasted losses was used to produce a
form of symbolic violence and how this capital is more effective as it produces messages
addressed to the producers, i.e., policymakers and the judicature in this specific case. keywords: حسابداری انتقادی | روابط صنعتی | مداخلات فکری | انعکاس | Critical accounting | Industrial relations | Intellectual interventions | Reflexivity |

Social movement activists’ conceptions of political action and counter-accounting through a critical dialogic accounting and accountability lens
تصورات فعالان جنبش اجتماعی از کنش سیاسی و مقابله با حسابداری از طریق یک دریچه حسابداری گفتگوی انتقادی و پاسخگویی-2021 In the face of growing disaffection with neoliberalism and corporate social and environmental
accounting, critical accounting recognizes the potential of counter-accounting to open spaces for
democratic contestation and to advance progressive change. Critical dialogic accounting and
accountability (CDAA), for example, views counter-accounting as providing social movements
with opportunities to challenge neoliberal hegemony, to mobilize multiple publics and to
construct new social realities. However, the democratizing potential of counter-accounting is
contested within academia, and social movements’ views of counter-accounting as a politicizing
practice are not well understood. We extend CDAA theorizing by elaborating on the value of
counter-accounting in advancing democratic struggles against neoliberalism and illustrating how
an agonistic lens can be useful in framing social movements’ actions in these struggles. Social
movements’ conceptualizations of political action and counter-accounting are empirically
investigated through interviews with 25 social movement activists. Based on the interviews and
our CDAA lens, we propose possible areas for critical accounting collaborations with social
movements as they seek to effect progressive change. keywords: حسابداری دیجیتالی انتقادی و پاسخگویی | مبنی بر حسابداری | عذاب | جنبش های اجتماعی | نئولیبرالیسم | Critical dialogic accounting and accountability | Counter-accounting | Agonistics | Social movements | Neoliberalism |
