A tablet-based application for older adults to enhance memory: Communication with archiving stories

Sharing emotion is one aspect of communication between humans. Throughout human history people have regularly met face to face in order to share or collect information and to experience emotional interaction. As technology rapidly developed the means of communication have dramatically moved to online space through social communication methods or through online information spaces where people comment or write their ideas and thoughts. Although most audiences now use online communication methods, the older population has been relatively neglected in the industry because they are sometimes considered customers outside the major market. The main goal of this study was (1) to develop a technology-friendly interface design prototype based on a touch-based tablet application using universal design principles and (2) to assess the prototype design through several research methods such as field observation, surveys, and interviews. This study can expand designers’ knowledge for the next step of application of development for older adults. This study found that even though older adults are sometimes isolated from society, they might think of relationships as an important part of their later life. Although technology may be harder for older adults to learn, this study found it possible if older adults are willing to learn and use a communication application. This study also found that intuitive visual cues might play an important role in aiding older adults to grasp and understand the structure of an application. Technology-friendly interface design can enable older adults to use technology routinely in their daily lives. The designer’s role in this process would be to seek better understanding through the user study and to find the visual elements to provide a technology-friendly environment for older adults.
A Cost Benefit Analysis of introducing Electric Vehicles in Bhutan

Bhutan is reputed for its pristine environment and its unparalleled commitment towards environmental conservation. However, recent studies have found that carbon emissions are on the rise with rapidly increasing fossil fuel consumption, which now constitutes the most significant item in Bhutan’s import basket. While Bhutan is a net exporter of hydroelectric energy the import of fossil fuel offsets nearly 70% of the exports of electricity to India. In the aftermath of the recent balance of payments challenges with India, the country is compelled to consider alternative mobility options to reduce its dependence on fossil fuel imports and harness its abundant hydro-power, but more importantly, to serve as a model for conservation efforts. With the vision to become the first full-fledged electric-vehicle city in the world, Bhutan must mobilize significant institutional and financial resources. As a stepping stone towards this initiative the government is considering the replacing of a fleet of taxis with electric vehicle equivalents. The relative upfront costs of adopting an electric platform are considered a major deterrent notwithstanding the future stream of savings on account of lower energy and maintenance costs and the intangible benefits to society as a whole. Hence, this paper conducts a Cost Benefit Analysis of the initiative. While most studies focus only on the end-user, this study takes a more comprehensive approach by studying the costs and benefits to both users as well as society taking into consideration various assumptions and scenarios. The macroeconomic and microeconomic implications of this initiative are assessed, and policy recommendations are also offered. Under all scenarios the EV option emerges as the most preferred model. Even the baseline scenario in which no incentives are offered reveals a favourable outcome for the EV. However, these outcomes are assessed over a relatively long time span of 8 and 10 years which gives rise to a time inconsistency problem, which is why some intervention may be necessary to nudge individuals in favour of the EV option.
Offer quality affecting consumption of hospitality products and services in franchised restaurants in Nairobi Central Business district Kenya

The fast-food concept seems to attract franchisees and is growing rapidly in Kenya. The purpose of the study was to look into the offer quality affecting consumption of hospitality products and services in franchised restaurants in Nairobi Central Business Kenya. The objective of the study was to explore the extent to which offer quality affect consumption of hospitality products and services to achieve competitive advantage in Franchised Restaurants. The problem being investigated was why the offer quality is favouring some franchises and not others. It focused on food and beverage production and service techniques adopted to increase consumption. The research was carried out in the Nairobi CBD in franchised restaurants. The study adopted the descriptive research design. A census study was done on the 15 restaurants and their 15 managers in the CBD while systematic random sampling was done to select 10% of 3250 customers. The data was collected by use of questionnaires and interviews. Descriptive and inferential statistics were used for data analysis. The findings revealed that the quality of food and the price greatly influenced the consumption of the products and services.
Efficiency and Elasticity of Labor Use on Economic Sectors in Indonesia

The research objectives are: (1) to analyze the level of efficiency and elasticity of the use of labor in Gross Domestic Product (GDP) based on economic sectors in Indonesia in the period of 2010-2016, (2) to find out the changes/ transformations in the use of labor among the economic sectors in Indonesia in the period of 2010-2016. The analytical method used is a descriptive and analytical method of the Cobb-Douglass production function. The results showed that during the period of 2010-2016 there had been a decrease in the efficiency of labor absorption in GDP at an average of 6.5% per year. The values of labor elasticity against GDP during the period 2010-2016 are inelastic (e &lt;1) but it is still positive. This shows a tendency to decrease changes in employment absorption of GDP. There is still an incompatibility in the business field between the ability to contribute to GDP with the ability to absorb labor. When viewed from the contribution to GDP, the transformation from the agricultural sector to the industrial sector, the service sector field and other economic sectors have been successful, but when viewed from the absorption of labor, the transformation has failed.
Analytical Size Estimation Methodologies for Electrified Transportation Fueling Infrastructures Using Public–Domain Market Data

The proliferation of electrified transportation systems is envisioned as a promising solution that could significantly contribute to the reduction of environmental pollution. Deployment of properly sized fueling stations is contemplated as a critical step to set the stage for the transportation electrification. While several optimization-based sizing models are presented in the literature, analytical models to estimate the size of electrified transportation infrastructures are missing from prior studies. Such analytical models can readily be developed at the backend of globally accessible websites or software applications since they do not require any optimization solver. In such a case, public-domain data, such as market prices or transportation demand, from everywhere around the world can be inputted to the model, and various sizing parameters related to each location are returned to the user. To that end, this paper presents new analytical methodologies for the application to the size estimation of electric and hydrogen-based fueling stations as the two major foundations for electrified transportation. The ratings of various components are expressed in terms of the system operation percentage using the proposed formulation, and the desired ratings are selected at which the net profit reaches to the maximum point. Historical public-domain data from real-world systems are utilized for numerical evaluation of the proposed formulation. In addition, the estimation error of the proposed model is analyzed and compared with artificial intelligence-based models for validation purposes.
Small business owner’s perception of the value and impacts of sport tourism on a destination

Abstract Sports tourism is perceived to bring significant benefits to a community hosting a sporting event. This purpose of this study was to explore the perceptions of small business owners, who are also residents of a community, on the economic, environmental and social cultural impacts of sports tourism. The results uncovered the level of support for sports tourism among small business owners varied based on the type of small business. This study is an important contribution to the literature and has significant implications for destination marketing organizations, tourism planners, and sport tournament organizers attracting and planning sport events in cities.
The sustainability of family firms during an economic crisis

This paper presents the results from research into the survival of family and non-family firms. The research used the Competitiveness of Czech firms matrix from 2009. The study looked at firms which were able to survive the economic crisis and observed their characteristics. The results indicated that family firms survived the economic crisis at a higher rate than non-family firms, and also that some of the non-family firms became family firms. The results open up new areas of research concerning the source of family-firm resilience during a crisis.
How are Bankers Paid?

We empirically examine bank CEOs’ compensation. We find that bank CEOs (a) are paid less than their nonfinancial counterparts, an effect driven by the CEOs of small bank; (b) experienced declining compensation during 2007–2009 (the hardest-hit banks cut compensation more) but pay is now 24% higher than precrisis levels; (c) are paid more at larger banks, those with less nonperforming loans, those with a higher proportion of noninterest income, and those with less demand-deposit dependence; and (d) have pay highly sensitive to ROA and ROE, but not stock returns. Tail risk is higher when compensation depends more on short-term measures of performance.

Impacts of climate change on tomato, a notorious pest and its natural enemy: small scale agriculture at higher risk

Climate change (CC) clearly impacts food production, but risks on the climatic suitability of agricultural areas for vegetable crops, their pests and associated natural enemies are largely unexplored. Tomato, one of the most important vegetables in the world, is grown mostly outdoors, and may be severely impacted by CC. Farmers cultivating tomatoes need to adapt to an increase in the potential for outbreaks of pests favoured by CC and disruption of biological control, yet, no attempt has been made to simultaneously evaluate CC effects on a crop-pest-natural enemy system for tomato or any other crop. Here, we modelled the suitability of areas equipped with irrigation facilities (AEI) in 2050 for tomato, the two-spotted spider mite, Tetranychus urticae, a mite pest of tomato among more than 200 crops, and its key predator Phytoseiulus persimilis. We evaluated the suitability of AEI for tomato production under a 1.6 °C warming by 2050, within the targets of the Paris agreement. Projections show that climatic conditions become unsuitable for tomato production on 30%–100% of AEI for seven out of the 29 top tomato producing countries of the world. Model predictions suggest that two-spotted spider mite potential for outbreaks would increase substantially in nine countries in Europe, Africa and Asia, while biological control failures would occur globally. Model results have a significant relationship with growth rates for the three species measured in outdoor experiments, and farmer/expert perceptions on two-spotted spider mite outbreak severity captured via interviews. The expansion of AEI in other agricultural areas in the sub-Saharan Africa may offset losses of suitable land. However, several nations in the Middle East and South Asia with prevalent small scale agriculture would experience devastating impacts because of the unsuitability of conditions for tomato production and the potential increase in two-spotted spider mite outbreaks.
Calibration Strategies for Agent-based Simulation Models with Variability

During the development of an agent-based simulation model, the model often has to be calibrated, which means adjusting the parameters such that a reference system can be reproduced. A major problem in calibrating an agent-based simulation model is the variability of the results, due to random choices made by the agents. To reduce the variability, the numbers of agents has to be increased, which in return increases the computation time of the simulation. An attempted solution to this problem consists of increasing the numbers of agents gradually. This approach is tested with two different calibration algorithm: simulated annealing and evolutionary algorithm. Different updating schedules are applied on a test model and examined in terms of their running time and their performance. It is shown that a evolutionary algorithm with an increasing agent count manages to produce similar results as a standard calibration using only half the computation time. To conclude, the best performing calibration process is used to calibrate an existing agent-based model simulating a well known past influenza epidemic.
Remedies to inaccessibility of low-cost housing loan in Malaysia: using the qualitative approach

ABSTRACT Studies have shown that low-income earners (LIEs) faced encumbrances in gaining access to housing finance. Therefore, this study investigated the root-cause of inaccessibility of housing-loan and proffer pragmatic policy solutions so that Malaysian LIEs can access housing-loan to purchase homes via qualitative insight. To achieve this, 40 face-to-face oral interviews were conducted and validated via secondary sources. Findings show that ineligibility and inability to make down payment are the major reasons banks are reluctant to lend housing loan to LIEs. The root causes of the issues are bad status of Central Credit Reference Information System, lack of evidence of regular income, absence of collateral, inability to make down-payment, fear of inability to recover the loan and operating costs from the auction among others. Also, the rejection rate of LIEs housing loan application is about 70% with supporting evidence. A setting-up of a special housing loan scheme for LIEs across the country; government buy-up low-cost houses in the auction and placed them on rent-to-own scheme via independent agency while existing scheme sustained, intensified and strengthened among others were recommended as part of this paper’s contribution and implication with a view to ensuring LIEs gain access to homeownership via housing finance.
Financial statements according to the international financial reporting standards: requirements and realities of implementation

The purpose of the article is to study peculiarities of the information formation in financial statements in accordance with the requirements of international financial reporting standards (IFRS) and its importance for external users in a market environment. Research methods. In the process of research were used general philosophical and general scientific methods of knowledge of phenomena and processes: abstract and logical for interpretation of an essence of financial reporting; comparison, analogy and systematization for assessing the legal provisions and prerequisites for the introduction of international standards of financial reporting; monographic method for analysis of evolution of scientific achievements of domestic scientists regarding problems of financial reporting by economic entities in accordance with the requirements of international standards; empirical method for comprehensive assessment of the current state of the research object; evolutionary approach and historical method for formation of implementation stages of the international standards of financial reporting in Ukraine. Research results. In the process of studying issues regarding the formation of financial statements in accordance with the requirements of international standards, a number of prerequisites were introduced that preceded a need for financial statements to be prepared in accordance with the international standards. There were formed periods for implementation of IFRS in Ukraine, in particular: early period, transitional period, period of voluntary use, period of formation of institutional mechanism, and period of global euro integration processes. Elements of scientific novelty. The theoretical positions concerning the implementation of the international financial reporting standards were further developed, the authors' vision of an essence of financial reporting as a socially important information tool for representing the financial and property status and results of business entities of the market economy were formed. Practical significance. There were outlined approaches, which are expedient to use in two financial reporting systems (for SAS and IFRS), namely the method of transformation and the method of conversion. Tabl. : 3.

Later the intermediate nodes are allowed to recode the encoded data in the network. Through which the confidentiality and non-repudiation, key management, integration is achieved.
Exploring Social Accountability for Pervasive Fitness Apps

—Mobile fitness applications have gained increasing popularity to help users walk and exercise more. A key component in such apps is its ability to motivate users. Traditional gamification methods have focused on competition such as leaderboard for community users, self-reflection for individual users, or a combination of the two. Motivated by recent work showing a promising effect of social capital, we have designed and developed a mobile game, HealthyTogether, based on such ideas. We are further interested in how users behave in different settings of gamification methods compared to a baseline. To this end, we have designed and conducted an in-depth user study (N=24) involving 12 dyads playing these games in 4 conditions over a period of two weeks. We report here the design of the application as well as the user study. Among the various rewarding schemes, one that uses a hybrid concept of competition and social accountability gives the most desirable outcome.
The Role of Demographic Factors on Academic Social Networking Sites Use Behaviour from Academic Researchers Perspective

Academic Social Networking Sites (ASNS) is one of the important tools to facilitate the development of international collaborations among researchers. Academic researchers at different disciplines and different levels of their research activities are becoming more interested in ASNSs. Many factors impede using collaboration technology among academic researchers. Demography is one of those factors. The purpose of this paper is therefore to find out the differences among academic researchers’ ASNS use behaviour in terms of demographic factors. Due to lack of ASNSs studies especially which studies regarding the different type of ASNS users, the result of this research gains its importance. Survey-based questionnaire has been used for this study. Hypotheses were tested using Statistical Package for Social Science (SPSS) on data collected from 628 ASNS users. The results show that gender, age and experience are not significant predictors to academic researchers’ ASNS use behaviour.
