Challenges Encountered When Identifying Remote Stakeholders

Stakeholders play a major role in the adoption and acceptance of a software product. We find there are different perceptions of who is a stakeholder and different approaches to promoting their participation in software development. However, we also find that there the software engineering community does not address how stakeholders are identified in remote regions despite acknowledging that locality and culture typically have an impact on a software product. We discuss these issues in this paper. Author Keywords Stakeholders, remote regions, software development, participatory design.
Between risk and autonomy: producing subjects in group homes and supervised workshops for people with intellectual disabilities

Abstract This study focusses on the question of how the values of autonomy, self-determination, and independence influence people with intellectual disabilities who live in a social world of institutionalized care. It analyses policies and practices – everyday activities. Data collection took place during 240 h of participant observation in three group homes and one workshop for adults with intellectual disabilities in Austria. The analysis demonstrates that these organizations attempt to enhance the status of people cared for to that of an autonomous subject. But this project is failing, as these people do not have the practical knowledge required to fulfil the social demands of reason, responsibility for their actions and their physical integrity, and also to manage household tasks efficiently. Consequently, they assimilate to being dependent subjects. Two risk management strategies support this: everybody should be treated equally, plus the loss of responsibility outside the social world and in medical practices. Points of interest This article compares written guidelines and everyday activities in group homes and supervised workshops for people with intellectual disabilities in Austria. It wants to clarify the connections between everyday activities, disability, society, and personal aims. The written guidelines of institutions for people with intellectual disabilities support the idea that people should become more self-determined and independent. However, everyday activities reveal that in real life, it is more important to keep people safe and well-cared for. This mismatch also becomes visible in a conflict between the ideal that people in group homes should be autonomous and the demand that the caregivers minimize possible health risks. This study recommends accepting that all people are somehow dependent. Further, the aim of belonging to others should receive more attention in group homes and supervised workshops.
E-cien t Signal Detection for MIMO-OFDM System

Recently, the multiple-input multiple-output (MIMO) schemes have been proposed as e-cient solution for future wireless system. MIMO schemes can achieve a signiflcant increase in the bandwidth e-ciency as well as an improvement of the transmission reliability. In this pa- per, switching for the detection schemes based on channel condition is proposed in MIMO system. The QRD-M detection scheme has better performance and high complexity than the QRPIC detection scheme. Two detection schemes are e-cient switched based on channel condi- tion. Therefore the proposed detection scheme has little performance degradation, but it has low complexity.
Implicit Associations between Adverbs of Place and Actions in the Physical and Digital Space

Neuropsychological, behavioral, and neurophysiological evidence indicates that the coding of space as near and far depends on the involvement of different neuronal circuits. These circuits are recruited on the basis of functional parameters, not of metrical ones, reflecting a general distinction of human behavior, which alternatively attributes to the individual the role of agent or observer. Although much research in cognitive psychology was devoted to demonstrating that language and concepts are rooted in the sensorimotor system, no study has investigated the presence of implicit associations between different adverbs of place (far vs. near) and actions with different functional characteristics. Using a series of Implicit Association Test (IAT) experiments, we tested this possibility for both actions performed in physical space (grasp vs. look at) and those performed when using digital technology (content generation vs. content consumption). For both the physical and digital environments, the results showed an association between the adverb near and actions related to the role of agent, and between the adverb far and actions related to the role of observer. Present findings are the first experimental evidence of an implicit association between different adverbs of place and different actions and of the fact that adverbs of place also apply to the digital environment.
Online Adaptive Neurofuzzy Based SVC Control Strategy for Damping Low Frequency Oscillations in Multi-Machine Power System

An online auxiliary control was designed for Static Var Compensator (SVC) to improve the poorly damped oscillations in multi-machine power system subjected to small and large disturbances. This paper presents auxiliary control based on Adaptive NeuroFuzzy (ANF) control using triangular membership function. Such a model free based control does not require any prior information about the system and is robust to system changes quickly. To minimize the cost function and to tune the parameters of the antecedent and consequent part of the proposed control, a Gradient Descent (GD) learning algorithm is used. The time domain simulation results were carried out for two machine test system for four different cases. In order to exploit the performance and robustness of ANF control, the results were compared with conventional PI and no control. Simulation results and performance indices reveal that the proposed control outperforms during various fault conditions and hence improves the transient stability to a great extend.
Cryptococcus neoformans VNII as the Main Cause of Cryptococcosis in Domestic Cats from Rio de Janeiro, Brazil

Cryptococcosis is a systemic fungal disease acquired from contaminated environments with propagules of the basidiomycetous yeasts of the Cryptococcus neoformans and C. gattii species complexes. The C. neoformans species complex classically comprises four major molecular types (VNI, VNII, VNIII, and VNIV), and the C. gattii species complex comprises another four (VGI, VGII, VGIII, and VGIV) and the newly identified molecular type VGV. These major molecular types differ in their epidemiological and ecological features, clinical presentations, and therapeutic outcomes. Generally, the most common isolated types are VNI, VGI, and VGII. The epidemiological profile of cryptococcosis in domestic cats is poorly studied and cats can be the sentinels for human infections. Therefore, the present study aimed to determine the molecular characterization of Cryptococcus spp. isolated from domestic cats and their dwellings in the metropolitan area of Rio de Janeiro, Brazil. A total of 36 Cryptococcus spp. strains, both clinical and environmental, from 19 cats were subtyped using multilocus sequence typing (MLST). The ploidy was identified using flow cytometry and the mating type was determined through amplification with specific pheromone primers. All strains were mating type alpha and 6/36 were diploid (all VNII). Most isolates (63.88%) were identified as VNII, a rare molecular type, leading to the consideration that this genotype is more likely related to skin lesions, since there was a high percentage (68.75%) of cats with skin lesions, which is also considered rare. Further studies regarding the molecular epidemiology of cryptococcosis in felines are still needed to clarify the reason for the large proportion of the rare molecular type VNII causing infections in cats.
Dual Head and Dual Attention in Deep Learning for End-to-End EEG Motor Imagery Classification

Event-Related Desynchronization (ERD) or Electroencephalogram (EEG) wavelet is essential for motor imagery (MI) classification and BMI (Brain–Machine Interface) application. However, it is difficult to recognize multiple tasks for non-trained subjects that are indispensable for the complexities of the task or the uncertainties in the environment. The subject-independent scenario, where an inter-subject trained model can be directly applied to new users without precalibration, is particularly desired. Therefore, this paper focuses on an effective attention mechanism which can be applied to a subject-independent set to learn EEG motor imagery features. Firstly, a custom form of sequence inputs with spatial and temporal dimensions is adopted for dual headed attention via deep convolution net (DHDANet). Secondly, DHDANet simultaneously learns temporal and spacial features. The features of spacial attention on each input head are divided into two parts for spatial attentional learning subsequently. The proposed model is validated based on the EEG-MI signals collected from 54 subjects in two sessions with 200 trials in each sessions. The classification of left and right hand motor imagery in this paper achieves an average accuracy of 75.52%, a significant improvement compared to state-of-the-art methods. In addition, the visualization of the frequency analysis method demonstrates that the temporal-convolution and spectral-attention is capable of identifying the ERD for EEG-MI. The proposed machine learning structure enables cross-session and cross-subject classification and makes significant progress in the BMI transfer learning problem.
A Study on the Secondary Vocational Students’ Intention of Enter to Higher Education in the Underdeveloped Areas of Western China Based on the Theory of Planned Behavior

Secondary vocational students are the participants of the connection between secondary vocational education and higher education. Their intention of entering higher school determines whether China can smoothly promote the cultivation of high-quality technical talents. Because the proportion of secondary vocational education going to higher school in the underdeveloped areas of western China is relatively low. Therefore, this study is based on the theory of planned behavior to explore the factors that influence the intention of secondary vocational students in underdeveloped areas in western China. Through the questionnaire survey, it is found that there are significant differences in the students’ intention of enter to higher education in terms of gender, grade, and academic performance. Students’ attitude toward entering higher education, subjective norm, and perceived behavioral control can predict their intention of entering higher education. But in the end, only the attitude toward entering higher education and the perceived behavioral control are included in the regression equation. Finally, based on the results of this research, four suggestions are put forward.
Copper and zinc hydroxychloride cosupplementation improve growth performance and carcass and reduce diarrhea frequency in grower-finisher pigs

Abstract This study investigated copper (Cu) and zinc (Zn) hydroxychloride cosupplementation on the growth performance, diarrhea frequency, carcass, meat quality, and antioxidant activity in grower-finisher pigs. A total of 256 pigs were used from 70 to 154 days (d) of age, distributed in four treatments, with eight pigs in each pen and eight replications per treatment. Diets were provided to grower pigs from 70 to 112 days old and in the finisher, 112 to 154 days old. Copper was considered the low level at 100 mg Cu/kg and 90 mg Cu/kg, respectively, and 150 mg Cu/kg in both periods as high in the grower and finisher periods. In the grower and finisher period, zinc was cosupplemented in the diet at 80 mg Zn/kg and 70 mg Zn/kg, respectively. In the diets, T1 and T2 groups are the traditional inorganic sources for minerals (copper sulfate, CuSO4; zinc oxide, ZnO) and T3 and T4 hydroxychloride sources (copper hydroxychloride, CHC, and zinc hydroxychloride, ZHC). The flavomycin was associated with treatments with low Cu content in the inclusion of 50 g/ton. The experimental design was in randomized blocks, the data were submitted to analysis of PROC MIXED in SAS, the PDIFF test analyzed the treatment effect. At the finisher period, pigs fed both minerals from hydroxychloride source had a higher BW 154 d, average daily gain (ADG) 70 to 154 d, the hot and cold carcass weight and frequency of normal feces than those fed 150 mg Cu/kg and Zn from a traditional inorganic source (P < 0.05). The animals fed low Cu levels of the sulfate source had a higher ADG 70 to 154 d than those fed high Cu levels of the same source (P < 0.05). Pigs fed 150 mg Cu/kg cosupplemented with Zn from a hydroxychloride source had the highest carcass length (P < 0.05). There was no difference among the treatments for meat quality (P > 0.05). Pigs fed 150 mg Cu/kg and Zn from a traditional inorganic source had a higher superoxide dismutase (SOD) activity than the other treatments (P < 0.05). Animals fed low Cu levels from hydroxychloride had a higher malondialdehyde (MDA) formation than those fed sulfate source, regardless of the Cu levels and those fed high Cu levels of hydroxychloride (P < 0.05). In conclusion, 150 mg Cu/kg as copper sulfate cosupplemented to zinc oxide in the diet of growing and finishing pigs impairs the growth performance, carcass and increases diarrhea frequency, and copper and zinc hydroxychloride cosupplementation improves these characteristics.
Stability of nanobeams and nanoplates with defects

The sensitivity of critical buckling load and critical stress concerning different geometrical and physical parameters of Euler-Bernoulli nanobeams with defects is studied. Eringen’s nonlocal theory of elasticity is used for the determination of critical buckling load for stepped nanobeams subjected to axial loads for different support conditions. An analytical approach to study the impact of discontinuities and boundary conditions on the critical buckling load and critical stress of nanobeams has been developed. Critical buckling loads of stepped nanobeams are defined under the condition that the nanoelements are weakened with stable crack-like defects. Simply supported, clamped and cantilever nanobeams with steps and cracks are investigated in this article. The presented results are compared with the other available results and are found to be in a close agreement.
Learning through policy transfer? Reviewing a decade of scholarship for the field of transport

ABSTRACT Attempts to pursue sustainable mobility face widespread challenges. One key way of approaching these challenges is through policy transfer and policy learning; indeed, the practice of learning from elsewhere is encouraged at various levels of government. This paper contends that a better understanding of what facilitates learning through policy transfer might support further change, yet such examinations remain underdeveloped in the field of transport. This paper synthesises key concepts and factors that drive this learning process, by reviewing 65 papers on transport policy published between 2011 and 2020. Our findings testify to the growing prevalence of policy transfer research and emerging critical perspectives on the transfer and translation of global ideas. We uncover critical factors of the learning process, including settings where learning takes place, inter-actor relations, and organisational and institutional patterns. While most papers reviewed here aimed to examine learning, few employ theories to measure the concept. Consequently, one of our main conclusions is that relatively little is known about how and to what extent learning, triggered by experiences from other contexts, is actually transformed into action. Suggestions include more systematically focusing on organisational and institutional dimensions and concerted trans-disciplinary efforts to close the gap between research and practice.
Circularly polarised microstrip antenna with a tuning stub

A simple circular polarisation (CP) design of microstrip antennas using a tuning stub is proposed and studied. It is also demonstrated that, by applying this CP design method to a circular microstrip patch with a cross slot having equal slot lengths, a compact circularly-polarised microstrip antenna can easily be implemented, with much more relaxed manufacturing tolerances as compared to the case of using a cross slot of unequal slot lengths. Details of the antenna designs are described, and experimental results are presented and discussed.
An Engineering Vehicle Positioning System for Carrying Rocket Using Extended Kalman Filter

In order to verify a quick launching system for rockets with small and medium sizes, an engineering vehicle localization and navigation sub-system is presented in this article. The structure of the launcher includes the front board and two cylindrical landmarks on both sides. When the vehicle gets close to the launcher, two 2D laser scanners on the vehicle detect the launcher reliably. And an extend Kalman filter is used to estimate the vehicle’s pose relative to the launcher. The localization and navigation results show that the lateral positioning error is smaller than 1cm so that the vehicle could align with the launcher accurately.
The Mediating Effect of Coping Style on Physical Activity and Negative Affect Caused by Public Health Emergencies: Evidence from Chinese College Students

In this study, we explored the relationship between physical activity (PA), coping style (CS) and negative affect caused by public health emergencies (PHENA), to examine if CS can play a mediating role between PA and PHENA, and analyzed the different effects of positive coping (PC) and negative coping (NC). Using the method of random sampling, 700 students from four universities in Beijing and Shanghai were recruited to complete questionnaires about PA, CS and PHENA. Data collection was conducted through online and offline questionnaires. Firstly, there is a significant correlation between PA, CS and PHENA. Secondly, PA can negatively predict PHENA, and PA has positive impact on PC and negative impact on NC. Thirdly, the mediating role of NC related to PHENA is significant, the mediating role of PC related to PHENA is not significant. College students’ participation in physical activity can reduce the probability of adopting negative coping mechanisms, thereby alleviating the PHENA.
DArTseq Genotypic and Phenotypic Diversity of Barley Landraces Originating from Different Countries

Landraces are considered a key element of agrobiodiversity because of their high variability and adaptation to local environmental conditions, but at the same time, they represent a breeding potential hidden in gene banks that has not yet been fully appreciated and utilized. Here, we present a genome-wide DArTseq analysis of the diversity of 116 spring barley landraces preserved in the collection of the Polish gene bank. Genetic analysis revealed considerable variation in this collection and several distinct groups related to the landraces’ country of origin and the grain type were identified. The genetic distinctness of hulless accessions may provide a basis for pro-quality breeding aimed at functional food production. However, the variable level of accession heterogeneity can be a significant obstacle. A solution to this problem is the establishment of special collections composed of pure lines that are accessible to breeders. Regions lacking genetic diversity have also been identified on 1H and 4H chromosomes. A small region of reduced heterogeneity was also present in the hulless forms in the vicinity of the nud gene that determines the hulless grain type. However, the SNPs present in this area may also be important in selection for traits related to grain weight and size because their QTLs were found there. This may support breeding of hulless forms of spring barley which may have applications in the production of high-quality foods with health-promoting values.
A new method to suppress harmonics using /spl lambda//4 bias line combined by defected ground structure in power amplifiers

A new /spl lambda//4 bias line combined by a dumb-bell shaped defected ground structure (DGS) is proposed to suppress harmonics in power amplifiers. The proposed DGS bias line maintains the required high impedance even after DGS is inserted, while the width and length of the /spl lambda//4 bias line are broader and shorter than those of conventional bias lines. When the DGS bias line is used in power amplifiers, the third harmonic components as well as the second harmonic are reduced, because of the increased slow-wave effect over wide harmonic band. It is shown that the reduction of the third harmonic component, the improvement of 1 dB compression point, and power added efficiency are 26.5 dB, 0.45 dB, and 9.1%, respectively.
Conflicting estimates of natural geologic methane emissions

Global bottom-up and top-down estimates of natural, geologic methane (CH4) emissions (average approximately 45 Tg yr–1) have recently been questioned by near-zero (approximately 1.6 Tg yr–1) estimates based on measurements of 14CH4 trapped in ice cores, which imply that current fossil fuel industries’ CH4 emissions are underestimated by 25%–40%. As we show here, such a global near-zero geologic CH4 emission estimate is incompatible with multiple independent, bottom-up emission estimates from individual natural geologic seepage areas, each of which is of the order of 0.1–3 Tg yr–1. Further research is urgently needed to resolve the conundrum before rejecting either method or associated emission estimates in global CH4 accounting.
Innovative plAnt Protein fibre and Physical activity solutions to address poor appEtite and prevenT undernutrITion in oldEr adults – APPETITE

Older adults with poor appetite are at higher risk of undernutrition due to the role of appetite as a key driver of food intake. Dietary protein and fibre are critical nutrients in this population, and enhancing their intake is vital to preventing undernutrition and maintaining organ function and health. In APPETITE , a transdisciplinary consortium of experts from eight institutions in six European countries will collaborate to design potentially effective interventions to enhance protein and fibre consumption of community-dwelling older adults with poor appetite, thereby addressing undernutrition through a targeted nutrition-and physical activity-based strategy. Older adults with poor appetite will first be evaluated using a mixed-methods approach to gain insights into their nutritional and behavioural preferences. Working with this target group, innovative, acceptable and affordable food products will be developed that combine several domestic plant proteins and dietary fibres. Mechanistic insights will be gained by examining the impact of selected products and physical activity on digestibility, amino acid bio-availability and whole-body protein metabolism. In a multi-country, randomised controlled intervention trial, the impact of two new food products, provided as part of a personalised diet, a physical activity programme, and their combination will be determined. APPETITE will improve our understanding about plant-based protein and fibre products and their metabolic and clinical effects. It will create
