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.

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.

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.

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.

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.

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.

The purpose of this paper is to review policy or guidance on the implementation of Section 5(4) written by NHS mental health trusts in England and health boards in Wales.

A Freedom of Information request was submitted to all trusts in England (n=57) and health boards in Wales (n=7) asking them to provide a copy of any policy or guidance on the implementation of Section 5(4). Documents were analysed using content analysis. Specific attention was given to any deviations from the national Mental Health Act Codes of Practice.

In total, 41 (67.2 per cent) organisations had a policy on the implementation of Section 5(4). There was a high level of consistency between local guidance and the Mental Health Act Codes of Practice. There were however; different interpretations of the guidance and errors that could lead to misuse of the section. Some policies contained useful guidance that could be adopted by future versions of the national Codes of Practice.

The research has demonstrated the value of examining the relationship between national and local guidance. Further research should be undertaken on the frequency and reasons for any reuse of the section.

Greater attention should be given to considering the necessity of local policy, given the existence of national Codes of Practice.

This is the only research examining the policy framework for the implementation of Section 5(4).

This chapter examines the experience of Russia's cities in the implementation of smart solutions. Previous theoretical and empirical studies cover a variety of dimensions, involved in the concept of a smart city, and practical issues concerning technologies, urban management, business models which improve urban residents' quality of life through digital technologies, artificial intellect under the conditions of creating appropriate infrastructure. In this chapter, we present the results of the analysis of some significant information about smart solutions deployed in Russian cities nowadays. We show how smart solutions get allocated among Russian cities and among different domains of this kind of solutions. Unlike most of other countries, smart solutions in Russia are less concentrated in such domains such as sustainable development or transport. Instead, a large number of relevant projects in Russia are concentrated in the field of informatization of urban life and energy efficiency. This feature is associated with budget centralization, the implementation of national programs by the Russian Federal Government. Consequently, in general, the Russian model of a smart city is less focused on demand, but to a greater extent it can be classified as supply-driven.

More than 30 legal recyclables were proclaimed by Environmental Protection Administration (EPA) in Taiwan of those producers and importers are liable for paying a Resource Recycling Fee (RRF). The Resource Recycling Management Fund determines both the tariff of RRF and the subsidy rate for recycling activities based on a predetermined pricing formula and collects the revenue to finance its collection and disposal. While contemplating on whether to proclaim waste mattress as a legal recyclable, EPA is facing several critical challenges, particularly the lack of data required for setting a tariff–subsidy mix. In this chapter we critically review the formula and propose an innovative pricing rule. Also, we develop a science-based approach to demonstrate how a tariff–subsidy mix could be determined under the circumstance of data deficiency. By doing so, we avoid not only the difficulty in solving the nonhomogeneous and nonautonomous first-order difference equation that governs the stock accumulation of waste mattress but also the distributed lag model of multiperiods linking quantity of mattress discarded and the quantity of new mattress sold. Such an approach could be applied to the durables for recycling pricing particularly when relevant data are limited.

The purpose of this research is to elaborate on the game strategies of technology parks and innovation networks that influence the provision of sustainable development of countries.

The method of formalisation, statistical method and the game theory of alternate reality are used in this research.

The study of the main characteristics of the influence of integration structures (technology parks and innovation networks) of the leading countries in the sphere of sustainable development (Finland, Sweden, Denmark and Germany) and identification of their game strategies of development allow stating that the selected directions of strategic management and interaction are efficient, ensuring the business interests and supporting the social sector and ecologisation of the country. There is an effect of the use of the development strategies of the leading integration structures on the economic component of countries, since, despite the influence of the global crisis and domestic problems, they demonstrate high economic indicators of development.

The scientific novelty and value of this research consist in the elaboration of the theoretical framework on the strategic directions of the development of integration structures (technology parks and innovation networks) and their influence on the achievement of the SDGs.

The purpose of the chapter is to describe the concept of conflicts of socio-economic systems on the basis of the theory and methodology of the systemic approach.

The authors use the provisions of the systemic approach.

It is determined that dynamic socio-economic system is susceptible to conflicts, which, according to the Systemic approach, are bifurcation points. The features of conflict that allow defining it as a bifurcation point are its short duration, violation of sustainability of socio-economic system, uncertainty of consequences, influence on the system on the whole (cascade effect), and multiplicity of scenarios of development of socio-economic system after the conflict.

Studying conflict with the help of the theory and methodology of the systemic approach allowed determining the fact that conflict is a violation of order in a socio-economic system (which specifies definition of conflict and its essence) and could be evaluated through the measure of the system’s order (which specifies methodology of conflict evaluation). Moreover, conflict in a socio-economic system emerges not at once – it is accumulated under joint negative influences of internal and external factors. Further, the performed research allows specifying the classification of conflicts, which is offered in previous chapters – according to scenarios of development of socio-economic system after the conflict, normal (leading to normal change of system), abrupt (leading to abrupt change of the system), and attraction (all following states of the system are sustainable) conflicts are possible.

This paper aims to achieve scale, efficiency and mitigate high monitoring costs, and explores the efficacy of micro equity finance at the enterprise level. The study compares the economic features of the proposed framework with interest-based debt finance.

This study uses a mathematical model to highlight the problem of agency costs including adverse selection and moral hazard.

Debt finance requires frequent repayments and indebtedness for financial inclusion. Conversely, the Islamic equity modes of financing in their current baseline structure suffer from high agency costs. By using enterprise level finance and distinct entry criterion for availing Islamic debt-based and micro equity finance, Islamic microfinance institutions (IMFIs) can reach the right targets and effectively mitigate the problem of adverse selection and high monitoring costs. The study suggests a framework in which equity financing could be used to fund microenterprises that will employ poor people with related skills.

As the preferable modes of Islamic finance, i.e. Musharakah and Mudarabah, are not used by Islamic financial institutions (IFIs), empirical analysis of performance is not possible as they are rarely used.

The study suggests a workable model that can use Islamic equity-based modes of financing to improve microfinance outreach and achieve scale. The use of equity financing will help the Islamic finance industry to move toward its egalitarian vision, and the practical implementation of the model will help in reducing poverty in the Muslim majority countries.

Muslim countries host half of global poverty, even though their share in global population is only one-fourth. Hence, there is need for solutions in achieving scale in poverty alleviation efforts.

Using a mathematical model, the paper presents agency problems in Islamic microfinance and proposes a solution through distinct entry criterion and enterprise level micro equity finance.

This study aims to assess future prospects for Russian energy exports until 2040, as global energy markets are undergoing major changes, with possible impacts on Russia.

Qualitative and quantitative approaches are integrated under a proposed foresight framework. The qualitative method involves an expert survey aimed at identifying major energy trends and their influence on Russia. As the trends are validated, an algorithm is proposed to assess the contribution of separate trends to Russian energy exports.

Experimental quantitative scenarios are conducted to assess the prospects for Russian energy exports until 2040 under the given exogenous scenario calculations of the IEA. Factor analysis allows for an assessment of the contribution of separate factors in dynamics of net energy imports into the regional economies. The future prospects for fossil fuels’ exports on regional markets are considered. Priority markets for Russian energy exporters are identified.

The results of the paper may be used by decision-makers for adjustments in the system of government policy or corporate strategy.

The paper provides an algorithm to assess energy export flows to macroregions based upon the synthesis of quantitative and qualitative information. Experimental scenario calculations of the Russian fossil fuels’ exports are provided. Strategic decision-making map is elaborated.

The purpose of this paper is to present a framework for empirically studying knowledge creation (KC) with phenomenological approach and propose that understanding interaction as play conceptualized by Hans-Georg Gadamer allows examining KC starting from the idea of a human being interacting in the events of co-creation. The presented framework is used to examine KC in a community of librarians and teachers collaborating to promote children’s joy of reading.

An ethnographic approach is applied to investigate knowledge-creating interaction in a working community. The triangulated data consist of ethnographic observations and video recordings of the community’s gatherings, its members’ interviews and produced documents.

The phenomenological conceptions of temporality of a human being and play are suitable for understanding being in the knowledge-creating interaction, as they give means to understand the meaningfulness of the past experiences, but promote an open attitude toward the future possibilities in a way which promotes KC. Studying interactive events allows understanding how KC can be examined as a collective accomplishment. The playful mode of being in the event was seen as a way to use the limited time available for interaction effectively.

The empirical study was conducted in one community, and further research is needed to test the developed approach in other contexts.

The results may be utilized to develop organizational circumstances, which promote KC by acknowledging the meaningfulness of interaction.

The study presents a novel way to conceptualize and examine KC as an experience and an event with phenomenological approach.

The purpose of this paper is to report on the content of local policies on engagement and observation written by National Health Service (NHS) organisations in England and Wales.

Engagement and observation policies were obtained from all (n = 61) NHS mental health trusts in England and health boards in Wales via a Freedom of Information Act 2000 request. Data were analysed using content analysis.

All organisations had a specific policy referring to either “observation and engagement” or “observation”. The policies varied considerably in quality, length, breadth and depth of the information provided. Significant variations existed in the terminology used to describe the different types of enhanced observation. Inconsistencies were also noted between organisations regarding: which members of the clinical team could initiate, increase, decrease and terminate observation; who could undertake the intervention (for example students); and the reasons for using it. Finally, despite rhetoric to the contrary, the emphasis of policies was on observation and not engagement.

This research has demonstrated the value of examining local policies for identifying inconsistencies in guidance given to practitioners on the implementation of engagement and observation. Further research should be undertaken to explore the impact of local policies on practice.

Local policies remain variable in content and quality and do not reflect contemporary research. There is a need to produce evidence-based national standards that organisations are required to comply with.

To the best of the author’s knowledge, this is the first research in 20 years examining the local policy framework for the implementation of engagement and observation.
