Abstract

Purpose

The purpose of this study is to develop the dictionary with grammar and multiword structure has to be used in conjunction with sentiment analysis to investigate the relationship between financial news and stock market volatility.

Design/methodology/approach

An algorithm has been developed for calculating the sentiment orientation and score of data with added information, and the results of calculation have been integrated to construct an empirical model for calculating stock market volatility.

Findings

The experimental results reveal a statistically significant relationship between financial news and stock market volatility. Moreover, positive (negative) news is found to be positively (negatively) correlated with positive stock returns, and the score of added information of the news is positively correlated with stock returns. Model verification and stock market volatility predictions are verified over four time periods (monthly, quarterly, semiannually and annually). The results show that the prediction accuracy of the models approaches 66% and stock market volatility with a particular trend-predicting effect in specific periods by using moving window evaluation.

Research limitations/implications

Only one news source is used and the research period is only two years; thus, future studies should incorporate several data sources and use a longer period to conduct a more in-depth analysis.

Practical implications

Understanding trends in stock market volatility can decrease risk and increase profit from investment. Therefore, individuals or businesses can feasibly engage in investment activities for profit by understanding volatility trends in capital markets.

Originality/value

The ability to exploit textual information could potentially increase the quality of the data. Few scholars have applied sentiment analysis in investigating interdisciplinary topics that cover information management technology, accounting and finance. Furthermore, few studies have provided support for structured and unstructured data. In this paper, the efficiency of providing the algorithm, the model and the trend in stock market volatility has been demonstrated.

Abstract

Purpose

We examine the joint demand for components of a household’s diet diversity and its relationship with household and regional characteristics that embody diverse food access and utilization constraints within the framework of the dietary patterns of rice producers in Peru.

Methodology/approach

We use multivariate probit regression to account for the simultaneous nature of the choice of different dietary group components.

Findings

There are diverse food intake patterns for households, depending on their wealth, education, demographic structure, market access and geographic location, as well as past shocks. There are also several obesogenic foods that are complements to consumption, with milk being a strong substitute for some of them. Of particular concern is the high vulnerability of female-headed households to low consumption of micronutrient-rich foods as well as the high vulnerability of households with children to high consumption of beverages with added sugars. Climate shocks are also highly associated with poor diet quality.

Practical implications

Results show the important influence of trade on household nutrition and food security. They indicate that policy and program recommendations should focus on nutrition information (such as labeling requirements) and education so that consumers can make informed decisions. They also suggest that policy makers should focus on how to make healthy foods available during crises to prevent health issues after economic and climatic shocks.

Abstract

Purpose

Malaysia is considered to be a relatively young country as compared to other older countries such as Japan, China and Australia in terms of the ageing population. However, until 2035, Malaysia will be in the ageing group countries as 15% of the entire population will be above 60 years of age. This situation is quite alarming as more and more ageing care centres will be required to fulfill the ongoing demands of the ageing population. The elderly care centres in Malaysia are categorised as public (sponsored by the government), private, and charity based that comes under religious centres. Currently, there are about 365 registered elderly care centres working in the main states of Malaysia, including Sabah and Sarawak, two states of the East Malaysia. Due to the importance of ageing population issues, the present study is conducted to explore the demographics facet of Malaysian’s elderly care centres. The main reason behind that lies on the fact that many of these centres are still labelled as being not well equipped and lacking behind in trained staff, equipment and also suffering from severe financial constraints but some still capable of working on a sustainability basis.

Design/methodology/approach

Qualitative Research Strategy has been adopted, and 28 centres throughout Malaysia are included in this study. About 18 Operators from different centres and 15 caregivers were interviewed to get the holistic view of ageing care and facilities in their respective centres.

Findings

The results highlight that the majority of centres are not receiving any financial help from the government, and few centres are doing small business such as supplying consumable medical and non-medical items and providing renting and rehabilitation centres facilities to sustain. The caregivers are facing issues such as excess workload, less salary, peer conflicts and non-cooperative centre leadership.

Originality/value

The present study may help to provide useful information to the policymakers, which enables them to formulate the strategies for ageing care centres in Malaysia. As this study provides insight of components that have an impact on the overall wellbeing of elderly care centres, hence, it could help the care services providers to act as a rising star for Malaysian’s social life comfort.

Abstract

For at least the last 10 years, the Russian authorities have been declaring the need to move to an innovative path of economic development. The government actively initiates and applies various instruments and measures to promote innovation. However, the effectiveness of the Russian innovation policy is still in question. The chapter examines the evolution of state policy to foster innovation growth in Russia since 2000 and describes some sets of achievements and problems for different stages of this policy. In addition to analysis of changes in the innovation sphere at the macro-level, we discuss the primary motivations and limitations at the micro-level (firm level). As a result, the critical institutional barriers to innovation-based growth are revealed. In the same time, certain successes have been achieved in some sectors, and we consider various opportunities to improve Russian technological and innovation policy.

Abstract

This study aims to investigate the effect of the crisis on entrepreneurial activities and how it can be relieved. Specifically, we explore how the positive effects of the human capital (self-confidence, opportunity alertness, and risk willingness) on startup activities are changed after the global financial crisis. Additionally, we explore how knowing an entrepreneur boosts up these relationships. We applied data from the Global Entrepreneurship Monitor (GEM) about prospective women entrepreneurs in China in 2006–2007 (precrisis time) and 2009–2010 (postcrisis time). Results show a sharp drop in effect size of self-confidence and opportunity recognition upon women's entrepreneurial actions; however, the global financial crisis nullified the effect of fear of failure on potential women entrepreneurs' business activities. Furthermore, knowing an entrepreneur has no significant moderating effect. Theoretical and practical implications and directions for future research are discussed.

Abstract

The study finds the determinants of women empowerment measured in terms of domestic decision-making in a developing economy perspective by considering rural women in India. Women empowerment simply means giving opportunities to women to enable them to be socially and financially independent. Empowerment of women through investment in their education and health has a positive effect on economic growth. Almost 70% of Indian population lives in rural areas. If women in these areas are educated and empowered, they can contribute to the economic growth either directly or indirectly by improving health and education of the future generations. This study indicates that an employed woman, having her own income source, higher educational level, knowledge of legal rights, higher educational level of the mother of the woman, having property in her own name, more freedom of movement during her school days, having high self-esteem and belonging to a relatively affluent background, increases domestic making power of the women, and thus empowerment. Some possible policies are suggested for developing economies.
