Likelihood inference for exponential-trawl processes
Integer-valued trawl processes are a class of serially correlated, stationary
and infinitely divisible processes that Ole E. Barndorff-Nielsen has been
working on in recent years. In this Chapter, we provide the first analysis of
likelihood inference for trawl processes by focusing on the so-called
exponential-trawl process, which is also a continuous time hidden Markov
process with countable state space. The core ideas include prediction
decomposition, filtering and smoothing, complete-data analysis and EM
algorithm. These can be easily scaled up to adapt to more general trawl
processes but with increasing computation efforts.Comment: 29 pages, 6 figures, forthcoming in: "A Fascinating Journey through

How to Support Vulnerable Citizens during the COVID-19 Lockdown: A Community Initiative from Ubiquitous Network Perspectives
The current COVID-19 lockdown situation has had a negative impact on
people’s connectedness which also has an influence on the well-being of the citizens (Canady, 2020; Hare-Duke, 2019; Oe, 2020). The enhancement of human interaction and networking is a key topic to sustain people’s health, and this has been on the emergent agenda during the current COVID-19 situation (Oe, 2020). To tackle this issue, one theory that could be employed is the efficacy of community members’ engagement, as proposed by McMillian and Chavis (1986), who
summarised a key ‘sense of community’ model. This model suggests four main dimensions should be strengthened to engage community members in supporting vulnerable people: a sense of belonging, an emotional connection, fulfilment of needs, and influence (Bermea et al., 2019).
This conceptual paper aims to enhance the discussion of how best to support vulnerable isolated citizens during the COVID-19 lockdown situation. A proposition framework suggests actionable implications with tangible recommendations for the relevant stakeholders. The authors propose two key themes to be considered: (1) how to meet needs and provide support in the virtual network community, and (2) how to
implement assistive technologies as a ubiquitous network paradigm as a community safety net for all
Is Gamification a Magic Tool?: Illusion, Remedy, and Future Opportunities in Enhancing Learning Outcomes during and beyond the COVID-19
Gamification in education has been discussed with potential for further implementation at universities; however, practical suggestions concerning which key issues educators need to consider has far not been shared in academia. This study applied a qualitative approach using interview data with 24 students who participated in the business class with games as learning measures. It has found that most of them believed that gamification could be useful in reinforcing key themes and topics after having learnt them through traditional means: They appreciated the games as a supportive measure to ‘glue’ key knowledge to their learning. A significant drawback that they emphasised was that taking notes is not easy while they are involved in games, which made them unconfident and uncertain about the learning outcome. As a result, a conceptual framework for pedagogy stakeholders was proposed for further discussion of how to design a gamification-based curriculum effectively
Techno-economic and environmental feasibility analysis of rice husks fired energy system for application in a cluster of rice mills
The agro-processing industries can play a critical role in the development of sustainable and clean energy systems. The lack of knowledge about the technical and economic viability of agro-waste to energy is a major barrier to the successful implementation of such energy systems in developing countries, especially sub-Saharan Africa countries. This paper presents the techno-economic-environmental assessment of a cluster of rice mills located in Abakaliki, Nigeria, as a provider of clean energy. The cluster of rice mills can sustainably fulfil its energy needs through the application of organic Rankine cycle based combined heat and power plant fired by rice husks. Three scenarios of the plant were proposed and investigated for complete information. The rice husk from the cluster can provide daily 20–30 MWh and 4–91 MWh of electrical power and thermal power, respectively, at 14.5–21% efficiency. A tonne of rice husk can provide 0.45–0.65 MWh of electricity; that the unit cost of electricity from the proposed system is between 0.12 and 0.159/kWh for the diesel generator currently in use. About 270–483 kg of CO2/MWh can be saved by the proposed combined heat and power system in relation to the current use of Lister diesel generators. The proposed plant has the potentials to support the Nigerian Nationally Determined Contributions to the Paris Agreement. The work also presents an appropriate business model and policy pathway for sustainable cottage rice processing industries
Vertical integration in production and services: development in transaction cost economics
In this paper, we first establish the core, fundamental concepts of Williamson's TCE, examining the different governance structures or the institutional alternatives that TCE theory proposes. We go on to describe some critical considerations and theoretical proposals that correspond fundamentally to Williamson's heuristic model, the integration of incentives in organizational forms, idiosyncratic demand, and how the concept of transaction is conceived in general.Peris-Ortiz, M.; Bonet, F.; Rueda Armengot, C.
