Abstract This paper discusses structuring of hardware and software for an autonomous social robot. It shows that the real-world social robot operations face the challenge of environmental variability and uncertainty of the objective parameters. Thus, a social robot must be capable of situation analysis for better autonomy. We propose a modular distributed structure of the control system. Separate modules monitor the status and control the subsystems of the robot. General coordination of subsystems is provided by the Supervisor module. For the robot to function autonomously, the Supervisor must be capable of situation analysis and its key functions: objective retrieval and analysis, situation description, configuring and strategizing the solution. The robot’s sensory inputs help acquire the objective and its parameters to describe the situation. Description relies on the database of a priori knowledge of the environment and its objects. Analysis is linked to a reduction in the uncertainty of the objective parameters and situation description. For a case study, the paper demonstrates a maze-solving strategy as affected by the situation.

Aquaculture Production

In Mexico, as in many other Latin American countries, the lack of a development plan and/or prevention in aquaculture to environmental variability is evident. In the State of Colima, aquaculture presents lags in terms of technical and productive capacity especially for growing tilapia Oreochromis spp. Surveys were performed to farmers and experts, in addition to consulting scientific literature sources, and identifying different risk factors arising from the practice of aquaculture in order to assess the vulnerability of the sector. The main risk factor associated with hydrometeorological phenomena, for which the need to define high-risk areas, even more, given the uncertainty of the same due to global climate change is recognized. This study proposes to implement a comprehensive program of technological conversion and control measures for alien species that also consider aquaculture production schemes based on the efficient use of water, and to consider using this endemic species for cultivation.

Status Of Women

This study examines the present status of women in the context of Electronic governance initiatives in Bangladesh. As a developing country, Bangladesh is stepping toward achieving E-governance where there is always a debate of the digital divide. Hence, this study tries to explore the challenges faced by women for access to and control over resources specifically the Information and Communication Technology tools or devices. It also aims to unveil the potentials of women's access and usage of such resources. This study employs survey data collected from study areas. Both urban and rural areas are chosen to get an overall scenario of women's status. This study is conducted in an inductive approach and findings are analyzed in a qualitative approach. The result shows that the status of women in access and usage of ICT varies in urban and rural areas due to some common constraints. The major findings of the study suggest that Information and Communication Technology has some potential for women empowerment which is explained as a case study. In this era of E-governance, most women are still facing gendered challenges such as lack of control over resources, awareness, education, and cybersecurity.

In the marine environment, an increasing number of studies have documented introgression and hybridization using genetic markers. Hybridization appears to occur preferentially between sister-species, with the probability of introgression decreasing with an increase in evolutionary divergence. Exceptions to this pattern were reported for the Cape hakes (Merluccius capensisandM. paradoxus), two distantly related Merluciidae species that diverged 3–4.2 million years ago. Yet, it is expected that contemporary hybridization between such divergent species would result in reduced hybrid fitness. We analysed 1,137 hake individuals using nine microsatellite markers and control region mtDNA data to assess the validity of the described hybridization event. To distinguish between interbreeding, ancestral polymorphism and homplasy we sequenced the flanking region of the most divergent microsatellite marker. Simulation and empirical analyses showed that hybrid identification significantly varied with the number of markers, model and approach used. Phylogenetic analyses based on the sequences of the flanking region of Mmerhk-3b, combined with the absence of mito-nuclear discordance, suggest that previously reported hybridization betweenM. paradoxusandM. capensiscannot be substantiated. Our findings highlight the need to conducta priorisimulation studies to establish the suitability of a particular set of microsatellite loci for detecting multiple hybridization events. In our example, the identification of hybrids was severely influenced by the number of loci and their variability, as well as the different models employed. More importantly, we provide quantifiable evidence showing that homoplasy mimics the effects of heterospecific crossings which can lead to the incorrect identification of hybridization.

The current situation with COVID-19 is changing our courses of action toward ensuring health security. This is particularly crucial in airports, which usually receive more than 300,000 travellers in one single day. In this work, we present an Internet of Things (IoT) network to monitor the status of toilets and improve their maintenance. The system is based on IoT networks with different sensors to control soap levels, room capacity, distances, temperature, and humidity. This information is processed by a multi-agent system that detects possible anomalies and makes decisions accordingly. A case study in a real environment is developed in order to demonstrate the usefulness of the system. The results show that the proposed method can be used to successfully manage and control airport toilets.

Disaster risk events always have impacts on disaster losses in terms of the sustainability. The phenomena of natural hazards continue to threaten the social and economic livelihoods of the community, ─ while policies and stipulated regulations for mitigating disaster risks reduction (DRR) endlessly become polemics both in national and local government institutions. The study was conducted to address public perceptions on the effectiveness of Indonesia’s Disaster Management Authorities in managing DRR across the archipelago. Relying on the coproduction principle, the author conducted a case-study through in-depth interviews and literature studies to gain public insights, including related encountered situations ─ revealing perceptions on the track-records of the performance of disaster management authorities in a SWOT analysis. The results indicated that both national and local disaster management authorities respectively are less effective due to the lack of effective communication, coordination, collaboration, and synchronization in managing DRR. Moreover, the scarcity of existing potential leaderships for decision makings through vertical and horizontal negotiations, ─ and lack of persuasive approaches for communities’ engagement at all risk cycles. The study highlighted the importance of reforming the status of national disaster management authority ─ thus, it is more powerful in functioning to command, monitor, and control the lower disaster risk institutions and be able to synergize implemented policies with other government institutions. The study also suggested increasing coproduction through public-private partnerships and philanthropies to upgrade innovations, education and training, also psychological healings as a recovery process for greater sustainable development.

The Status

Fracking has helped to usher in an era of energy abundance in the United States. This advanced drilling procedure has helped the nation to attain the status of the largest producer of crude oil and natural gas in the world, but some of its negative externalities, such as human-induced seismicity, can no longer be ignored. The occurrence of earthquakes in communities located at proximity to disposal wells with no prior history of seismicity has shocked residents and have caused damages to properties. It has evoked individuals’ resentment against the practice of injection of fracking’s wastewater under pressure into underground disposal wells. Though the oil and gas companies have denied the existence of a link between such a practice and earthquakes and the local and state governments have delayed their responses to the unforeseen seismic events, the issue has gained in prominence among researchers, affected community residents, and the media. This case study has offered a glimpse into the varied responses of stakeholders to human-induced seismicity in a small city in the state of Texas. It is evident from this case study that although individuals’ complaints and protests from a small community may not be successful in bringing about statewide changes in regulatory policies on disposal of fracking’s wastewater, they can add to the public pressure on the state government to do something to address the problem in a state that supports fracking.
