Authors: Niermann Dario , Trende Alexander , Ihme Klas , Drewitz Uwe , Hollander Cornelia , Hartwich Franziska
Published: November 2021

The quickly rising development of autonomous vehicle technology and increase of (semi-) autonomous vehicles on the road leads to an increased demand for more sophisticated human–machine-cooperation approaches to improve trust and acceptance of these new systems. In this work, we investigate the feeling of discomfort of human passengers while driving autonomously and the automatic detection of this discomfort with several model approaches, using the combination of different data sources. Based on a driving simulator study, we analyzed the discomfort reports of 50 participants for autonomous inner city driving. We found that perceived discomfort depends on the driving scenario (with discomfort generally peaking in complex situations) and on the passenger (resulting in interindividual differences in reported discomfort extend and duration). Further, we describe three different model approaches on how to predict the passenger discomfort using data from the vehicle’s sensors as well as physiological and behavioral data from the passenger. The model’s precision varies greatly across the approaches, the best approach having a precision of up to 80%. All of our presented model approaches use combinations of linear models and are thus fast, transparent, and safe. Lastly, we analyzed these models using the SHAP method, which enables explaining the models’ discomfort predictions. These explanations are used to infer the importance of our collected features and to create a scenario-based discomfort analysis. Our work demonstrates a novel approach on passenger state modelling with simple, safe, and transparent models and with explainable model predictions, which can be used to adapt the vehicles’ actions to the needs of the passenger.

Published: November 2021

Porcine circovirus 2 (PCV2), considered one of the most globally important porcine pathogens, causes postweaning multisystemic wasting syndrome (PMWS). This virus is localized in the mitochondria in pigs with PMWS. Here, we identified, for the first time, a mitochondrial localization signal (MLS) in the PCV2 capsid protein (Cap) at the N-terminus. PK-15 cells showed colocalization of the MLS-EGFP fusion protein with mitochondria. Since the PCV2 Cap also contained a nuclear localization signal (NLS) that mediated entry into the nucleus, we inferred that the subcellular localization of the PCV2 Cap is inherently complex and dependent on the viral life cycle. Furthermore, we also determined that deletion of the MLS attenuated Cap-induced apoptosis. More importantly, the MLS was essential for PCV2 replication, as absence of the MLS resulted in failure of virus rescue from cells infected with infectious clone DNA. In conclusion, the MLS of the PCV2 Cap plays critical roles in Cap-induced apoptosis, and MLS deletion of Cap is lethal for virus rescue.

Authors: Zammarchi Gianpaolo , Conversano Claudio
Published: November 2021

Eye tracking provides a quantitative measure of eye movements during different activities. We report the results from a bibliometric analysis to investigate trends in eye tracking research applied to the study of different medical conditions. We conducted a search on the Web of Science Core Collection (WoS) database and analyzed the dataset of 2456 retrieved articles using VOSviewer and the Bibliometrix R package. The most represented area was psychiatry (503, 20.5%) followed by neuroscience (465, 18.9%) and psychology developmental (337, 13.7%). The annual scientific production growth was 11.14% and showed exponential growth with three main peaks in 2011, 2015 and 2017. Extensive collaboration networks were identified between the three countries with the highest scientific production, the USA (35.3%), the UK (9.5%) and Germany (7.3%). Based on term co-occurrence maps and analyses of sources of articles, we identified autism spectrum disorders as the most investigated condition and conducted specific analyses on 638 articles related to this topic which showed an annual scientific production growth of 16.52%. The majority of studies focused on autism used eye tracking to investigate gaze patterns with regards to stimuli related to social interaction. Our analysis highlights the widespread and increasing use of eye tracking in the study of different neurological and psychiatric conditions.

Growth and Nutrient Uptake Characteristics of Heterosigma akashiwo (Raphidophyceae) under Nitrogen and Phosphorus Concentrations in the East China Sea
Authors: Yang Anqiang , Bellerby Richard G. J. , Wang Yanna , Li Xiaoshuang
Published: November 2021

Heterosigma akashiwo is classified as a harmful algal bloom (HAB) species that frequently occurs in eutrophic coastal waters and results in the contamination and mortality of fish and shellfish. The growth of H. akashiwo in four phosphate and nitrate concentration scenarios, representing the observed nutrient concentration ranges in the East China Sea (ECS), was evaluated to further understand the effect of nutrient concentrations on H. akashiwo blooms. The specific growth rate in the exponential growth phase (µ′) and the maximum cell density were lower (17–21% and 41%, respectively) under low phosphorus concentration scenarios, compared to the rates observed under high phosphorus concentration scenarios. The cellular nitrogen-to-phosphorus ratios of H. akashiwo were influenced by the initially supplied N:P ratio and the allocation strategy employed. Phosphorus concentration had a greater influence on the total growth of H. akashiwo than nitrate did, within the natural nutrient conditions of the ECS. These results could serve as a reference for coastal water management and marine ecological management and may be useful for further studies on the simulation and prediction of H. akashiwo blooms, particularly in the ECS.
Slaughterhouse Wastewater Treatment: A Review on Recycling and Reuse Possibilities

Published: November 2021

Slaughterhouses produce a large amount of wastewater, therefore, with respect to the increasing water scarcity, slaughterhouse wastewater (SWW) recycling seems to be a desirable goal. The emerging challenges and opportunities for recycling and reuse have been examined here. The selection of a suitable process for SWW recycling is dependent on the characteristics of the wastewater, the available technology, and the legal requirements. SWW recycling is not operated at a large scale up to date, due to local legal sanitary requirements as well as challenges in technical implementation. Since SWW recycling with single-stage technologies is unlikely, combined processes are examined and evaluated within the scope of this publication. The process combination of dissolved air flotation (DAF) followed by membrane bioreactor (MBR) and, finally, reverse osmosis (RO) as a polishing step seems to be particularly promising. In this way, wastewater treatment for process water reuse could be achieved in theory, as well as in comparable laboratory experiments. Furthermore, it was calculated via the methane production potential that the entire energy demand of wastewater treatment could be covered if the organic fraction of the wastewater was used for biogas production.
Current Status and Future Directions in Modeling a Transboundary Aquifer: A Case Study of Hueco Bolson
Authors: Talchabhadel Rocky , McMillan Helene , Palmate Santosh S. , Sanchez Rosario , Sheng Zhuping , Kumar Saurav
Published: November 2021

The Hueco Bolson aquifer is a binational aquifer shared by the United States of America (USA) and Mexico that is strongly interconnected with the transboundary river, Rio Grande/Rio Bravo. Limited recharge, increasing urbanization, and intensified agriculture have resulted in the over-drafting of groundwater resources and stressed the aquifer, threatening its sustainability if mitigation actions are not taken soon. Research indicates that the aquifer’s hydraulic gradients and flow directions have changed due to the high groundwater withdrawal rates from the two major cities—El Paso (USA) and Ciudad Juarez (Mexico). This paper presents a comprehensive overview of the Hueco Bolson aquifer modeling history and makes a case for future modeling and binational engagement efforts. First, we discuss the evolution of groundwater modeling for Hueco Bolson from the past to recent times. Second, we discuss the main water management issues in the area, including water quality and quantity, stakeholders’ participation, and climate change. To address the challenges of holistic water management, we propose developing a graphical quantitative modeling framework (e.g., system model and Bayesian belief network) to include experts’ opinions and enhance stakeholders’ participation in the model. Though the insights are based on a case study of Hueco Bolson, the approaches discussed in this study can provide new strategies to overcome the challenges of managing a transboundary aquifer.

Published: November 2021

The State of Louisiana is leading an integrated wetland restoration and flood risk reduction program in the Mississippi River Delta. East of New Orleans, Biloxi Marsh, a ~1700 km2 peninsula jutting 60 km north toward the State of Mississippi is one of few Delta wetland tracts well positioned to dissipate hurricane surge and waves threatening the city’s newly rebuilt hurricane flood defenses. Both its location on the eastern margin of the Delta, and its genesis as the geologic core of the shallow water St. Bernard/Terre aux Boeuf sub-delta, which was the primary Mississippi outlet for almost 2000 years, make Biloxi Marsh attractive for restoration, now that the Mississippi River Gulf Outlet deep-draft ship channel has been dammed, and 50 years of impacts from construction and operation have abated. Now, the cascade of ecosystem damage it caused can be reversed or offset by restoration projects that leverage natural recovery and increased access to suspended sediment from the Mississippi River. Biloxi Marsh is (1) geologically stable, (2) benefiting from increased input of river sediment, and (3) could be restored to sustainability earlier and for a longer period than most of the rest of the submerging Mississippi Delta. The focus of this review is on the Biloxi Marsh, but it also provides a template for regional studies, including analysis of 2D and 3D seismic and other energy industry data to explore why existing marshes that look similar on the ground or from the air may respond to restoration measures with different levels of success. Properties of inherent durability and resilience can be exploited in restoration project selection, sequencing and expenditure. Issues encountered and investigative methods applied in the Biloxi Marsh are likely to resonate across initiatives now contemplated to sustain valuable river deltas worldwide.

Published: November 2021

Uranium and nitrate are common groundwater pollutants near in situ leach uranium mines. However, we still lack techniques that can simultaneously immobilize uranium and reduce nitrate using a single bacterial species. In this study, the potential of simultaneous uranium immobilization and nitrate reduction by a single AFODN (anaerobic Fe(II) oxidizing denitrifier), Clostridium sp. PXL2, was investigated. Clostridium sp. PXL2 showed tolerance to U(VI) concentrations varying from 4.2 µM to 42 µM. The U(VI) immobilization and nitrate reduction rates in groundwater samples inoculated with this bacterium reached up to 75.1% and 55.7%, respectively, under neutral conditions. Exposure to oxidation conditions led to further U(VI) removal but did not show any noticeable effect on nitrate reduction. The U(VI) immobilization rate reached up to 85% with an increased Fe(II) initial concentration, but this inhibited nitrate reduction. SEM (scanning electron microscopy) coupled with EDS (energy dispersive spectroscopy) showed that the U(VI) immobilization was mainly due to sorption to amorphous ferric oxides. U(VI) and nitrate bioremediation by AFODNs, including Clostridium sp. PXL2, may provide a promising method for the treatment of uranium- and nitrate-contaminated groundwater after the in situ leach mining of uranium.

Published: November 2021

Coastal environments are exposed to numerous pressures that potentially affect marine soft bottom faunas. Among these pressures, organic matter enrichment is very frequent. Several indices based on living (Rose Bengal-stained) foraminiferal communities have recently been developed to assess the induced impact and determine the environmental quality of these environments. Here, we use an open waters Mediterranean Sea data set to test the benefits and drawbacks of four foraminiferal indices: (1) the effective number of species (exp(H’bc)), (2) the Tolerant Species Index for the Mediterranean (TSI-Med), (3) the Foraminifera AMBI (Foram-AMBI), and (4) the Foram Stress Index (FSI). These indices all intend to measure the response of the foraminiferal communities to organic matter enrichment, and therefore, their results should be very similar. We found that the diversity-based index, exp(H’bc), was not suitable to evaluate the environmental quality of our Mediterranean coastal settings, as it had a non-monotonic relationship with the organic matter enrichment gradient. The three indices based on groups of indicator species (TSI-Med, Foram-AMBI, and FSI) yielded fairly similar results. For Foram-AMBI, using only assigned species to calculate proportions of indicator species partly avoided to misinterpret the results. In TSI-Med, a correction based on sediment grain size is applied to distinguish between natural and anthropogenic organic enrichment. Such a correction could also be added to Foram-AMBI and FSI. The limits between the Ecological Quality Status (EQS) classes used for macrofauna were not adapted for Foram-AMBI. Here, we propose new EQS class limits for the Foram-AMBI as follows: very good: 0 ≤ x < 1.4; good: 1.4 ≤ x < 2.4; moderate: 2.4 ≤ x < 3.4; poor: 3.4 ≤ x < 4.4; bad: 4.4 ≤ x ≤ 6. These limits could evolve in the future as new data become available, especially with a poor and bad environmental quality.
A Weighted-Least-Squares Meshless Model for Non-Hydrostatic Shallow Water Waves

Published: November 2021

In this paper, an explicit time marching procedure for solving the non-hydrostatic shallow water equation (SWE) problems is developed. The procedure includes a process of prediction and several iterations of correction. In these processes, it is essential to accurately calculate the spatial derives of the physical quantities such as the temporal water depth, the average velocities in the horizontal and vertical directions, and the dynamic pressure at the bottom. The weighted-least-squares (WLS) meshless method is employed to calculate these spatial derivatives. Though the non-hydrostatic shallow water equations are two dimensional, on the focus of presenting this new time marching approach, we just use one dimensional benchmark problems to validate and demonstrate the stability and accuracy of the present model. Good agreements are found in the comparing the present numerical results with analytic solutions, experiment data, or other numerical results.
A Lane Level Bi-Directional Hybrid Path Planning Method Based on High Definition Map
Authors: Yang Bin , Song Xuewei , Gao Zhenhai
Published: November 2021

A global reference path generated by a path search algorithm based on a road-level driving map cannot be directly used to complete the efficient autonomous path-following motion of autonomous vehicles due to the large computational load and insufficient path accuracy. To solve this problem, this paper proposes a lane-level bidirectional hybrid path planning method based on a high-definition map (HD map), which effectively completes the high-precision reference path planning task. First, the global driving environment information is extracted from the HD map, and the lane-level driving map is constructed. Real value mapping from the road network map to the driving cost is realized based on the road network information, road markings, and driving behavior data. Then, a hybrid path search method is carried out for the search space in a bidirectional search mode, where the stopping conditions of the search method are determined by the relaxation region in the two search processes. As the search process continues, the dimension of the relaxation region is updated to dynamically adjust the search scope to maintain the desired search efficiency and search effect. After the completion of the bidirectional search, the search results are evaluated and optimized to obtain the reference path with the optimal traffic cost. Finally, in an HD map based on a real scene, the path search performance of the proposed algorithm is compared with that of the simple bidirectional Dijkstra algorithm and the bidirectional BFS search algorithm. The results show that the proposed path search algorithm not only has a good optimization effect, but also has a high path search efficiency.

Published: November 2021

The performance of batteries and on-board chargers (such as the volume in the car, energy storage capacity and charging speed) needs to be improved, which has become one of the main factors restricting the development of electric vehicles. The development of Vehicles to Grid technology puts forward higher requirements for chargers. With the development of Vehicles to Grid (V2G) technology, more realizable functions put forward higher requirements for chargers. To solve the problem of charging system in electric vehicle, a charging-driving integrated topology was designed, which makes full use of two-stator motor and inverters to be transformed to a charging system. The supercapacitor and the battery are used to form the hybrid power system. In the driving mode, the startup and acceleration performance of the vehicle are improved. In the charging mode, the various functions of Vehicles to Grid technology can be satisfied, and the electrical isolation is realized. This topology not only improves the power, but also greatly reduces the charging/discharging times of the battery, and improves the overall performance of the system. The feasibility is verified by simulation.
Analysing the Cost-Effectiveness of Charging Stations for Electric Vehicles in the U.K.’s Rural Areas
Authors: Sheng Kai , Dibaj Mahdieh , Akrami Mohammad
Published: November 2021

While U.K. authorities have attempted to tailor measures to boost sales of electric vehicles (EVs) and support citizens through different schemes, the size and geographic coverage of the existing charging network are insufficient, which undermines electromobility promotion. There are 15,853 public charging points installed in the U.K. as of 3 August 2021, and the demands for public EV charging are rising. For rural areas, there is little support from local authorities or private companies. To identify how a charging station can be installed and work, this study researches existing charging stations nationwide. Generally, most Public Charging Stations (PCS) in rural areas have unsatisfactory cost-effectiveness due to their long payback period. This paper presents how many rural PCS are able to afford the cost in the first eight years. Based on the ever-increasing demands of the market, EV producers are switching their business strategies. Meanwhile, the rural areas may become urban with the same definition. When it comes to the analysis of cost-effectiveness, it is possible for the PCS to bring more elements into the calculation. For Capital Expenditure (CAPEX) and Operation Expenditure (OPEX), the unnecessary cost leaves more profit space, like the possibility of unplanned maintenance costs.

Published: November 2021

The increase of greenhouse gas emissions into the atmosphere, and their adverse effects on the environment, have prompted the search for alternative energy sources to fossil fuels. One of the solutions gaining ground is the electrification of various human activities, such as the transport sector. This trend has fueled a growing need for electrical energy storage in lithium batteries. Precisely knowing the degree of degradation that this type of battery accumulates over its useful life is necessary to bring economic benefits, both for companies and citizens. This paper aims to answer the current need by proposing two research questions about electric motor vehicles. The first focuses on habits EV owners practice, which may harm the battery life, and the second on factors that may keep consumers from purchasing this type of vehicle. This research work sought to answer these two questions, using a methodology from data science and statistical analysis applied to three surveys carried out on electric vehicle owners. The results allowed us to conclude that, except for the Year variable, all other factors had a marginal effect on the vehicles’ absolute autonomy degradation. Regarding obstacles of the adoption of electric vehicles, the biggest encountered was the insufficient coverage of the network of charging stations.

Published: November 2021

LO ensino de Física no Brasil está voltado para a memorização e a preparação para provas, tornando o processo de ensino aprendizagem superficial. Os conceitos são ensinados na maioria das vezes sem uma contextualização e uma aproximação com o cotidiano, e ainda na Educação Básica tradicionalmente a Física Moderna e Contemporânea (FMC) não é parte obrigatória, tendo em vista a sua complexidade em conceitos e fórmulas. Diante desse contexto, propõem-se nessa pesquisa o uso de leituras paradidáticas como metodologia para trabalhar a FCM na Educação Básica. A pesquisa ocorreu de forma remota com 80 estudantes, com a utilização de um romance de autoria própria, onde são abordados temas da FMC. O trabalho tem como objetivo apresentar os conceitos da FMC, com uma linguagem mais acessível, inspiradora, visando a aprendizagem dos fenômenos físicos através da leitura. Os resultados mostraram um percentual de acerto maior que 75 % para as questões fenomenológicas e conteudista. Porém, sabe-se, que o ensino de Física é desafiador e que essa proposta não resolve todos os problemas, mas, pode ser um dos caminhos para consolidar melhor o ensino dessa ciência, que muito tem a contribuir com o desenvolvimento da sociedade.

Published: November 2021

Novas formas de apresentação do produto são oferecidas ao público no momento da compra no ponto de venda. Uma destas opções são os alimentos liofilizados. A liofilização é um processo de desidratação do alimento em que este passa por etapas importantes de congelamento, sublimação e dessorção. Com isso, o produto perde água como também o torna indisponível para uso pelos micro-organismos e seguro para o consumo. O alimento consegue manter seu valor nutricional e na reconstituição, ou seja, na reidratação se torna similar ao original por manter suas características. Sua praticidade é um fator importante para consumidores que não possuem tempo para preparar com calma seus alimentos, além de conseguir estender o tempo de prateleira. O objetivo desta pesquisa foi estudar através de levantamento bibliográfico o processo de liofilização na indústria de alimentos, suas vantagens, desvantagens e equipamentos necessários para a produção. Os resultados demonstram que esta tecnologia consegue eliminar a água de forma desejada, indisponibilizando-a para micro-organismos e mantém maior teor de proteínas e lipídios.

Os sedimentos desempenham um papel importante nos ecossistemas aquáticos como: o destino de xenobióticos, pois refletem a quantidade corrente do sistema aquático podendo ser usados para detectar a presença de contaminantes não solúveis. Assim sendo a análise de sedimentos é de fundamental importância, principalmente quando se quer avaliar o nível de contaminação em ecossistemas aquáticos isto se deve a uma das suas características potenciais de acumular metais pesados e disponibilizá-los para coluna d’água, processos estes que ocorrem em função das alterações de pH, potencial redox, oxigênio dissolvido, ação microbiana, turbidez, dentre outros, no ambiente impactado, podendo afetar a qualidade da água e desenvolver processos bioacumulativos (transferência do contaminante na cadeia trófica) nestes. Por outro lado, a matéria orgânica, também é um problema para esses ecossistemas, pois quando em excesso, causado geralmente pelo lançamento de esgotos, altera as proporções estequiométricas de C:N:P no sedimento modificando os ciclos químicos e biológicos do sistema aquático, visto que nesses ambientes, a regeneração de nutrientes a partir dos sedimentos representa um elo fundamental entre a disponibilidade de elementos na coluna d'água e os processos bênticos. O objetivo principal deste trabalho foi realizar a caracterização físico-química do sedimento da Laguna da Jansen em duas estações diferentes chuvosa (inverno) e seca (verão), a fim de entender o comportamento físico-químico deste em relação à carga de esgoto lançada.

A Project Management Maturity Model helps organizations measure and mature their practices in project, program and portfolio management, through the definition of knowledge improvements in their processes. In Mexico, there are states with higher growth in the development of new projects, as has been seen in the last 20 years in the state of Baja California Norte. The national observatory reported that “the population of professionals in the state reached 305,374 people”(SNE, 2020). Therefore, it is intended to know if this sector of the population knows or applies any maturity model in their work.Therefore, a new maturity model is proposed that combines the strengths of the best-known models in the literature and proposes a plan of strategic actions aimed at maturity. The level of maturity of project management and individual, group and institutional competencies of this population in the state was analyzed by means of a multidimensional survey. To check its validity, exploratory factor analysis was applied. Knowledge in project management processes was found to have maturity level 3. However, the mission, vision and institutional competencies barely reached a level 2. Which suggests that the BajaCalifornian managements should work on these aspects. The new culture proposes an action plan that aligns with the strategies and fosters maturity in any organization

Most nations of the world are faced with the problem of minimizing poverty and other challenges and Nigeria is not an exception. Nations of the world have devised ways to end these challenges. And one of the ways out of these challenges is the introduction of sustainable development goals as organizing principles for meeting human development goals and to sustain the natural systems to provide natural resources and ecosystem services upon which the ecosystem and the society depend. Another major goal of sustainable development is how education can be used for national development. It is the focus of this paper to point out how social studies can be utilized in achieving the junior secondary school education program for sustainable development. The method used by this research is a theoretical framework.
HyP-ABC: A Novel Automated Hyper-Parameter Tuning Algorithm Using Evolutionary Optimization

Machine learning techniques lend themselves as promising decision-making and analytic tools in a wide range of applications. Different ML algorithms have various hyper-parameters. In order to tailor an ML model towards a specific application working at its best, its hyper-parameters should be tuned. Tuning the hyper-parameters directly affects the performance. However, for large-scale search spaces, efficiently exploring the ample number of combinations of hyper-parameters is computationally expensive. Many of the automated hyper-parameter tuning techniques suffer from low convergence rates and high experimental time complexities. In this paper, we propose HyP-ABC, an automatic innovative hybrid hyper-parameter optimization algorithm using the modified artificial bee colony approach, to measure the classification accuracy of three ML algorithms: random forest, extreme gradient boosting, and support vector machine. In order to ensure the robustness of the proposed method, the algorithm takes a wide range of feasible hyper-parameter values and is tested using a real-world educational dataset. Experimental results show that HyP-ABC is competitive with state-of-the-art techniques. Also, it has fewer hyper-parameters to be tuned than other population-based algorithms, making it worthwhile for real-world HPO problems.
Quo Vadis? Richting vinden als je je verloren voelt
Authors: Kets de Vries Manfred F.R.
Published: November 2021

Geschreven in een tijd van wereldwijde pandemie, waarin we gedwongen zijn om eeuwenoude existentiële vragen onder ogen te zien: Waarom zijn we hier? Quo Vadis? Het thema is buitengewoon relevant voor leiders, managers en iedereen die betekenis en authenticiteit in zijn werk en leven wil brengen. Manfred Kets de Vries betoogt dat we deze fundamentele en verontrustende vragen aan de orde moeten stellen als we volledig en zinvol willen leven. Te veel mensen worden op maandagochtend wakker en doen hetzelfde als elke maandag. Ze gaan naar hun werk en functioneren op de automatische piloot zonder zich af te vragen wat hun doel is. Maar hoe kunnen we ervoor zorgen dat ons leven rijk, zinvol en bevredigend is? Hoe weten we dat we op de goede weg zijn? Dit is een boek over de dood en de angst voor de dood, over angst en absurditeit; maar het gaat ook over uithoudingsvermogen, eerlijkheid, welzijn, verantwoordelijkheid, leven met harde waarheden, betekenis creëren en geluk. Quo Vadis? laat ons voluit kijken naar de dingen die we liever niet zien. Het is een boek dat geen blad voor de mond neemt, maar verre van somber is. In plaats daarvan laat Kets de Vries zien dat ons leven wordt verrijkt, en ons vermogen om betekenis te geven en geluk te vinden wordt vergroot, wanneer we de onvermijdelijke prijs erkennen die we moeten betalen voor het kennen van onze eigen geest en het begrijpen van ons onvermijdelijke einde.
Inhibitie en sensorische gevoeligheid in volwassenen met autisme1

Published: November 2021

This current article describes the results and conclusions of the PhD-thesis (2014- 2018) of the first author. During these four years, the University of Amsterdam and the dr. Leo Kannerhuis (specialized center for people with autism) have collaborated in several studies to examine the relationship between psychophysiological measures, specifically heart rate variability and skin conductance, and autism symptoms in adults with a diagnosis of autism spectrum disorder (ASD). The main question was whether individual differences in inhibition and sensory sensitivity in adults with ASD could be explained by the way the autonomic nervous system functions and reacts. More knowledge on which factors might contribute to the large individual differences seen in ASD, could in time lead to more specialized and personally adjusted treatments. Besides these studies on inhibition and sensory sensitivity, we have also validated an autism-specific sensory sensitivities questionnaire, which is available for the clinical practice.

The pattern of development in a city is mostly governed by urban dynamics, with population increase being the primary driving force. Built-up cover is the most important predictor of urban expansion. Zuru metropolis in Kebbi State has witnessed remarkable developmental activities caused by human influences such as buildings, road constructions, and population growth for over decades. Urban growth was ascertained for a period of 30 years through the analysis of Landsat imagery of 1988, 1998, 2008 and 2018. The datasets were classified into five (5) land covers, namely, built-up, water body, rocky surface, vegetation, and others. Quantitative assessment of the urban growth was ascertained by computing post-classification LC dynamics and Land Consumption Rate/Land Absorption Coefficient (LCR/LAC). The results showed that the built-up cover (urban area) conspicuously increased with area of 693.35 ha, 728.74 ha, 5210.5 ha and 6845.75 ha respectively for the period of study (1988 – 2018). The increment in built-up area was indicative of population growth from 1988 to 2018. The study revealed that between 1988 to 2018 showed that built-up increased by 11.78%, while rocky surface and water body have shrunk by 16.44% and 0.02% respectively, which can be attributed to anthropogenic activities in which rocky surface and waterbody have been transformed into built-up cover. It further revealed that the urban area experienced crowdedness in the years 2008 and 2018 respectively due to high LCR values of 2.71% compared to LCR values of 0.0714% and 0.0558% in 1988 and 1998. Land transformation into urban area and spread of the population to the outskirts of the study area was prominent between 1998 and 2008 due to high LAC value of 0.0998. The study concluded that there was transformation of rocky surface and waterbody into urban area, which was caused by population growth, human and agricultural activities in Zuru metropolis.

Interest in the innovation of business models of companies in scientific research and man-agement practice has grown significantly over the past decade. It is critically important to analyze and understand the structure of the business model and its changes caused by strategic initiatives. Currently available approaches do not provide reliable guidelines, especially in uncertain and highly unstable situations associ-ated with rapid technological development. The approach presented in the article is based on the methodology of system modeling, which presents business models as complex systems with dynamic interdependencies, where intellectual capital plays a key role.
