The Influence of Expectations Regarding Performance on the Acceptance of Mobile Phone Banking Services by Smallholder Farmers: A Case of Smallholder Grape Farmers in Dodoma Region, Tanzania

This study uses a cross-sectional survey design to examine the influence of expectations regarding performance on the acceptance of mobile phone banking services by smallholder farmers in Dodoma Region, Tanzania. A total of 360 smallholder farmers were selected randomly for the study. The collected data was analysed using multiple linear regression to assess the relationship between expectations regarding performance and acceptance of mobile phone banking services. The study’s findings showed that expectations regarding performance measures (job fit, perceived usefulness, extrinsic motivation, and outcome expectations) have good predictive potential in explaining smallholder farmers' adoption of mobile phone banking services. The findings suggest that smallholder farmers have trust (i.e. perceived usefulness), in using a mobile phone banking system to improve agricultural commercialization. The findings also emphasize that smallholder farmers believe (i.e. job fit) that using mobile phone banking technology is beneficial to them. Furthermore, smallholder farmers believe that people who engage in farming activities are likely to achieve the desired results if rewards and/or incentives are given (i.e. extrinsic motivation). The study draws attention to mobile phone banking service providers to fulfil the expectations of smallholder farmers by providing services that address smallholder farmers’ needs. Finally, policy attention should focus on the expected performance of mobile phone banking services used by smallholder farmers in rural areas.

This paper conducts an in-depth study on this pain point and proposes the concept and implementation method of a cross-domain instant messaging reminder service system for mobile office, focusing on solving the problems of: cross-domain isolated boundary exchange of message reminders, timeliness and delivery rate guarantee of message reminders, and security check filtering of message contents. Technically, on the side of mobile office platform, based on AMQP technical framework and protocol, the cross-domain isolated border message queue push and synchronization services are built, which are real-time, reliable and high-throughput.

Policy Learning and the Diffusion of Autonomous Vehicle Policy in the American States

This study examines the multifaceted mechanisms driving the adoption of autonomous vehicle (AV) policy in the United States. Drawing from diffusion and network governance theories, it explores the intricate interplay between state governments, private industry, and shared mobility services in shaping AV policies. Several states like California, Nevada, and Texas have emerged as frontrunners in AV testing and innovation. However, policymakers grapple with unique challenges related to AV technology, including safety, liability, and infrastructure enhancement, necessitating innovative policy solutions. As AVs signify a transformative shift in transportation, state governments assume a pivotal role in policy innovation and experimentation. Using a blend of dyadic quantitative analysis and qualitative interviews, this study examines to what extent policy learning predominantly drives AV policy adoption. In doing so, we explore specific diffusion mechanisms, including policy learning and competitive dynamics, to understand how they shape the early adoption of AV policies across states. We find substantial evidence for interstate learning facilitated by intergovernmental organizations and the private sector.

Assessing individuals’ attitude and behavioural intention to use dietary and fitness mobile applications: evidence from India

PurposeThe purpose of this paper is to identify and examine the determinants of individuals’ attitude (ATT) and behavioural intention (BI) to use dietary and fitness mobile apps in the context of India.Design/methodology/approachThe present study develops a conceptual model by incorporating additional variables such as health consciousness (HC), perceived trust (PT), social influence (SI) and personal innovativeness (PI) into the original technology acceptance model (TAM). These constructs were extracted from existing theories and literature on technology adoption, individuals’ health beliefs and personality traits. The conceptual model has been empirically tested and validated by applying structural equation modelling using STATA version 15. The data was collected from both potential and actual users of dietary and fitness mobile apps through a structured questionnaire, both online and manually. Following a convenience sampling approach, a total of 450 respondents from Delhi national capital region (NCR) were contacted, of which 264 valid responses were considered for final analysis.FindingsThe results revealed that of all the factors predicting individuals’ “attitude” towards the use of dietary and fitness apps, perceived usefulness was found to be the most significant followed by PI and PT. Similarly, behavioural “intention to use” was most strongly determined by an individual’s attitude towards the usage of dietary and fitness apps followed by SI.Practical implicationsFindings of the study offer meaningful insights and implications for academics and practitioners. Mobile app developers and service providers can gain an understanding of the consumer’s behaviour towards adoption of dietary and fitness apps and improve the app’s utility, service quality, interface and features in view of the empirically validated determinants of such behaviour. Furthermore, it is essential for the service providers to undertake promotional efforts to not only create awareness of the availability of such apps but also at the same time educate people on the needs, functionalities and utilities they offer. Also, to gain a wider acceptance of the apps, focus on more communication and gamification/ entertainment features is required.Originality/valueThis study adds value by identifying the factors from varied perspectives (technical, social, health and personal) impacting individuals’ attitude and BI to use an innovative health intervention i.e. dietary and fitness mobile apps in a developing economy. Furthermore, the study proved the robustness of extended TAM in the area of healthcare. Lastly, this paper is among the few papers in the Indian context that assessed the adoption of dietary and fitness mobile apps.

Mobility of older people in public spaces from agender perspective

For older people, asufficient mobility offer is an essential prerequisite for participation in social life and abetter quality of life. The goal should be self-determined everyday mobility that enables asatisfying and healthy life. Mobility depends on diverse individual abilities and needs. On the other hand, social structures as well as regulatory and spatial framework conditions limit the realisation of mobility services and their transport infrastructure. These framework conditions are characterised by the perception of social roles, the availability of resources and gender-specific attributions. For example, care and caring work is predominantly the responsibility of women in the age group of 50years plus. The availability of transport infrastructure is geared towards goals that are characterised by the needs of gainful employment and not the goals of care work. Conversely, the availability of flexible means of transport, such as cars, also decreases for women in old age for economic reasons. For this reason, mobility planning should take greater account of specific needs, such as orientation towards care objectives, counselling, and health services and place agreater focus on the local area. For elderly people, especially women, security needs are often an important factor in the decision to become mobile or to forego mobility. This includes perceived subjective safety, accessibility and protection from weather conditions such as slippery surfaces or exposure to excessive heat. If these basic principles are taken into account, more people can be guaranteed self-determined participation in social life.

Exploring Financial Risks in Relation to Performance of MPESA Agents in Rural Areas, Kenya

The growth of mobile banking services, specifically Mpesa, has transformed financial transactions in Kenya, particularly in marginalized and rural regions. Ever since Safaricom introduced Mpesa in 2007, it has enabled various financial transactions like money transfers, bill payments, savings, and loans, becoming vital to Kenya's financial infrastructure. In rural areas, Mpesa shops are at risk of facing financial challenges which can impact their operations and long-term success. This research investigates how liquidity, credit, and operational risks affect the financial performance of Mpesa outlets in rural Kenya. The mismatch between cash coming in and going out results in liquidity risks, which can cause service interruptions and unhappy customers. Credit risks, resulting from borrowers failing to repay loans on time or defaulting, put pressure on cash flow and the stability of finances. Operational risks like technical failures, fraud, and regulatory non-compliance pose additional threats to the functionality and customer trust of the shops. By thoroughly analyzing pertinent literature and empirical data, this research investigates the way in which these risks interplay and impact the economic sustainability of Mpesa shops. The results are intended to guide improved risk management methods and policy suggestions to strengthen the resilience and sustainability of Mpesa agents, guaranteeing ongoing availability of crucial financial services in rural Kenya.

Multiple shared mobility services under competition: Empirical evidence for public acceptance and policy insights to sustainable transport

Traffic congestion and roadside emissions are severe and common problems in metropolitans. As a promising and sustainable solution to mitigating these vehicle externalities, shared mobility reduces the required vehicle fleet size for serving a given level of demand by sharing a vehicle among travelers with similar schedules and itineraries. Public acceptance is the key to the success of shared mobility development. This study investigates the acceptance of drivers and passengers of two typical competing shared mobility modes, car-pooling and taxi ride sharing, taking Hong Kong as a case study. For an empirical evaluation, an on-street stated preference survey was conducted, and 829 respondents, including 257 private car owners and 572 non-private car owners were interviewed about their travel preferences in three given hypothetical scenarios. In total, 2,487 observations were collected for calibrating two proposed logit-based discrete choice models for drivers and passengers. The model results show that the out-of-pocket cost, in-vehicle travel time, and out-of-vehicle time are key factors influencing travelers’ decisions toward car-pooling and taxi ride-sharing. An equilibrium model was proposed and an iteration solution procedure was applied to obtain a convergent solution to balance the demand and supply of drivers and passengers for car-pooling services. Furthermore, sensitivity analyses were carried out to examine the effects of variations in proportions of travel cost and taxi fare shared by passengers for car-pooling and taxi ride-sharing, and to assist in the formulation of relevant transport policies.

Cross-corpus speech emotion recognition with transformers: Leveraging handcrafted features and data augmentation

Speech emotion recognition (SER) stands as a prominent and dynamic research field in data science due to its extensive application in various domains such as psychological assessment, mobile services, and computer games, mobile services. In previous research, numerous studies utilized manually engineered features for emotion classification, resulting in commendable accuracy. However, these features tend to underperform in complex scenarios, leading to reduced classification accuracy. These scenarios include: 1. Datasets that contain diverse speech patterns, dialects, accents, or variations in emotional expressions. 2. Data with background noise. 3. Scenarios where the distribution of emotions varies significantly across datasets can be challenging. 4. Combining datasets from different sources introduce complexities due to variations in recording conditions, data quality, and emotional expressions. Consequently, there is a need to improve the classification performance of SER techniques. To address this, a novel SER framework was introduced in this study. Prior to feature extraction, signal preprocessing and data augmentation methods were applied to augment the available data, resulting in the derivation of 18 informative features from each signal. The discriminative feature set was obtained using feature selection techniques which was then utilized as input for emotion recognition using the SAVEE, RAVDESS, and EMO-DB datasets. Furthermore, this research also implemented a cross-corpus model that incorporated all speech files related to common emotions from three datasets. The experimental outcomes demonstrated the superior performance of SER framework compared to existing frameworks in the field. Notably, the framework presented in this study achieved remarkable accuracy rates across various datasets. Specifically, the proposed model obtained an accuracy of 95%, 94%,97%, and 97% on SAVEE, RAVDESS, EMO-DB and cross-corpus datasets respectively. These results underscore the significant contribution of our proposed framework to the field of SER.

Optimal design and fabrication of frame structure for dual-arm service robots: An effective approach for human–robot interaction

Rapid advancement in robotics technology has paved the way for developing mobile service robots capable of human interaction and assistance. In this paper, we propose a comprehensive approach to design, fabricate, and optimize the overall structure of a dual-arm service robot. The conceptual design phase focuses on both critical components, the mobile platform and the manipulation system, essential for seamless navigation and effective task execution. In the proposed system, the distribution of the robot payload in terms of region, maximum stress, and displacement is examined, comprehensively analyzed, and compared with the relevant works. In addition, to enhance the system’s efficiency while minimizing its weight, we introduce a lightweight design approach in which Finite Element Analysis is utilized to optimize the frame structure. Subsequently, we fabricate a physical prototype based on the derived model. Finally, we provide a kinematic model for our dual-arm service robot and demonstrate its efficacy in both control and human–robot interaction (HRI) tasks. Experimental results indicate that the proposed dual arm design can achieve a significant weight reduction of 25% from the original design while still performing actions smoothly for HRI tasks.

A regression-content analysis approach to assess public satisfaction with shared mobility measures against COVID-19 pandemic

IntroductionThe transportation sector was severely impacted by the COVID-19 pandemic, with shared mobility services being the most affected due to concerns from the public regarding the high likelihood of being a vector of the virus. Although studies have evaluated the impact of the COVID-19 pandemic on shared mobility, a deeper understanding of public satisfaction with the measures adopted during COVID-19 has not been explored. MethodsThis study utilized data collected in the Summer of 2020 across the United States to fill that literature gap. The study applied Ordered Probit (OP) models to explore the factors influencing an individual's confidence in not contracting COVID-19 while using shared mobility modes and Text Network Analysis (TNA) to understand the deeper reasons for their confidence levels. ResultsResults show a significant influence of sociodemographic factors, land-use/built environment, pre- and post-COVID travel behavior, and activity participation on respondents’ level of confidence for not contracting COVID-19. Only frequent public transit users showed that they have high confidence in not getting COVID-19 when they use any of the shared mobility options, while people who did not use public transit and those who frequently attend telehealth meetings had low confidence in the measures adopted by shared mobility providers. Furthermore, the text mining results indicated that cleanness was the key theme regardless of the confidence level of the respondents, except for rail and bus transit. However, we observed other patterns of themes across the types of shared mobility. ConclusionsThe study findings can be beneficial in the future to improve ridership during pandemics by considering perceptions and satisfactions of various users.

The Effect of Perceived Risk and Customer Experience on Loyalty Intention for Mobile Banking: The Moderating Role of Customer Satisfaction

In the banking industry, providing a range of conventional and high-tech services is crucial to ensure customer satisfaction. One area that requires attention is mobile banking services, which need to offer an engaging experience to keep customers satisfied and loyal. However, empirically, the evidence regarding the impact of the role of mobile banking customer satisfaction on loyalty intention seems to leave room for improvement. Research indicates that customer experience and the risks involved can have a significant impact on consumer satisfaction and loyalty intention. The study is conducted using explanatory research methodology, employing a quantitative approach and adhering to the positivist paradigm. This methodology aims to elucidate the causal relationship between variables, both through direct and indirect means. The research data was analyzed using PLS-SEM, which stands for Partial Least Square Structural Equation Method. The findings indicate that perceived risk has a detrimental influence on customer satisfaction, whereas customer experience has a beneficial effect. Research has demonstrated that customer satisfaction has a clear and substantial impact on the intention of customers to remain loyal. While all indirect links are supported, it is not possible to establish a direct relationship between perceived risk and customer experience on loyalty intention. The significance of customer satisfaction lies in its ability to connect perceived risk and customer experience results with loyalty intention. This study explores the implications for literature and management about mobile banking applications and the integration of perceived risk and customer experience in shaping customer satisfaction and loyalty in the banking sector. These advancements emphasize the significance of excellent customer experiences in enhancing customer happiness and loyalty. Companies must enhance client experience and strive to surpass expectations. Gaining a comprehensive understanding of the concept of "customer satisfaction" and its role as a mediator can help marketing and customer relationship management strategies effectively retain and attract customers.
