Reviews the content of the scholar Chanakya’s treatise, Arthasastra (economics). Written in the period 321‐296bc, it sets forth a framework for the economic management of India. Examines the Arthasastra’s teachings in the areas of agriculture, forestry, wildlife, mining and industries, and transport and trade. Reports that the economy was based on a system of coinage that had made barter of secondary importance and lists the prescribed sources of revenues such as taxes and fines and at the main heads of expenditure such as the maintenance of an army, a bureaucracy, social security measures and the upkeep of the King, his family and his court. Concludes that Chanakya’s Arthasastra is a monumental treatise of the ancient world that possesses great importance in the history of economics.

The purpose of this paper is to examine the psychometric properties of the positive and negative affect schedule (PANAS) in a sample of employees working in Indian manufacturing and service sector organisations.

The data were collected through self-administered structured questionnaire from 53 employees for the pilot study and 383 employees for the final study. For the psychometric evaluation of the PANAS, item analysis, reliability, exploratory factor analysis, convergent–discriminant validity and confirmatory factor analysis were performed.

Results reveal that the two-factor model of affect (positive and negative affects) is valid in the Indian manufacturing and service sector organisations.

Despite being the largest skilled labour facilitator for the work economy and second largest populated country, India lags behind in studies evaluating affect at work when compared to western nations. The present study was taken up to validate an instrument to measure affect at work in Indian manufacturing and service sector organisations, which is a new contribution in the field. Validation of this instrument would help in promoting studies on affect at work in India and comparative studies across cultures.

Drawing on broaden-and-build theory and promotion- and prevention-focus theory, the authors examined the role of positive and negative affectivity (PANA) on the riskiness of investment decisions. The authors also examined the mediating impact of financial knowledge network intensity (i.e. the level of communication with financially literate others in employees' social network) on the PANA—riskiness of investment decisions relationship.

Study 1 used a sample of undergraduate students and operationalized risk using a hypothetical investment scenario. Study 2 replicated and extended the Study 1 findings using employees and operationalized risk using their real-world investment allocations.

Both Studies 1 and 2 provided support for the negative direct relationship between NA and the riskiness of investment decisions. Study 2 found PA was marginally positively related to the riskiness of investment decisions. Financial knowledge network intensity mediated the relationship between NA and the riskiness of investment decisions in Study 2.

The findings suggest that employees who see the world in a generally negative light tended to have weaker financial knowledge networks, and this may be one mechanism that explains why they make low-risk investments.

Financial knowledge networks can provide access to critical information regarding investment opportunities. Socialization training or social mixers can be used to help employees build and improve their financial knowledge networks.

The authors integrate the research on PANA, social networks, and investment decisions to illuminate the social network processes that explain how affectivity impacts the riskiness of retirement investment decisions.

Use of hydrotreated, hydrocracked and catalytically dewaxed base oils in hydraulic and industrial applications is increasing on a global scale. The hydrogenation and dewaxing processes involved in the manufacture of these products can result in base oils of exceptionally low aromatic content and sulphur level and raised viscosity index (VI). The aromatic content, sulphur level and VI are parameters used by the American Petroleum Institute (API) to categorize the base oils as Group II or Group III. The performance of additives in these Groups II and III base stocks differs from that in Group I base stocks. In addition, different processes used by different manufacturers will not only create different base stock oxidative stability and solvency from that of Group I base stocks, it will also create differences between Group II base stocks and between Groups II and III base stocks. Several different base stocks have been examined using methods including mass spectrometry and aniline point. Variations in properties, such as aromatic content, cycloparaffinic content and aniline point, appear to relate to differences in oxidation stability and solvency. With the improved response of Groups II/III base stocks to antioxidants, a performance level of 10,000 hours or greater in the ASTM D 943 is common. This necessitates addition of specific antioxidants which result in extended oxidation performance but lead in some cases to the formation of insoluble degradation products in Group II/III base stocks, and more so in Group I base stocks. Phenolic‐ containing and phenolic‐free antioxidant systems have been identified that allow for extended oxidation stability in a wide range of Group II base stocks without sludge formation in either Group I, II or III base stocks.

The purpose of this paper is to uncover how emotions change (or remain constant) throughout the course of the vacation experience. Although the importance of affective experiences has been recognized in the literature, the momentary effects of each stage of the vacation on the overall appraisal of the experience deserve more attention.

A survey instrument was developed using the PANAS scale. Customers were asked for their emotions at different points of their vacation. Data were analysed using multinomial logistic regression, correlations and path analysis.

The results indicate that it is possible for guests to experience different affective states at different parts of the vacation experience. Furthermore, it is also likely for each service experience to impact the next service, in spite of the apparent distinction between them. Finally, the researchers noted the tendency of consumers to recall mostly positive emotions, thus raising the possibility of various kinds of memory biases in recalling a vacation experience.

Emotions are by their very nature momentary. Consequently, these affective states can change over time, especially over a vacation spanning several days. Therefore, the present research contributes to the literature, in that it measures emotions at various points in time, determines the impact of emotions towards one service provider on the next and ascertains the impact of said emotions on the overall vacation experience.

The main aim of the paper is to show the necessary convergence of two promising but under‐explored research fields, intellectics and inventics, into a new one, that of intellectual invention, and to discuss new ways of thinking which can be efficient in building an invention culture.

These purposes are achieved in an interdisciplinary way, in which the various scientific approaches are governed by a philosophical perspective that ensures the conceptual level and the unity of the discourse. The philosophical approach itself is practised in several specific fields and at various levels, being used in order to lay the foundations of a new domain of research. Specific theoretical problems are elucidated through concrete examples furnished by sciences and discussed from the perspective of inventics. Graphical representations help in giving a systemic and integrative perception of complex issues.

The paper defines in a comprehensive way the two partially studied and till now separately conceived research fields; delimitates and characterizes a new domain of study, of crucial theoretical and practical interest; analyses some types of intellectual techniques involved in all sorts of inventive activity; identifies the main new ways of thinking encouraged by the information technologies and shows their forms and manifestations, as well as the new values promoted by their development. There are proposed some improvements on sociological thinking from the perspective of inventive thinking. The emergence of an invention ethics is anticipated as a necessary component of an invention culture.

Proposes a new field of research, that of the intellectual invention, analyses the main instruments of its study and development, and uses the results of different sciences in order to lay the philosophical foundations of invention ethics as part of the future invention culture.

This chapter seeks to investigate the ways individualistic versus collectivistic values moderate neural responses to social exclusion among African American and White respondents. The author hypothesized that the vmPFC – a key brain region for emotion regulation – would correspond to collectivistic value moderation and the dlPFC – the cognitive control center of the brain – would be associated with individualistic value moderation.

This study used a virtual ball tossing game (Cyberball), where 17 African American and 11 White participants were excluded or included with ball tosses, while inside an fMRI scanner. Before the start of each round the participants were primed with individualism, collectivism or a comparison condition.

Results showed that (1) African Americans showed stronger neural responses to exclusion and (2) offered support for the hypothesis that the dlPFC showed greater activation in African Americans (compared to Whites) when they were primed with individualism values during exclusion. There was no support for the collectivism hypothesis.

Research limitations included a relatively small sample size (N = 28), a comparison of only two racial groups and that the partners in the game were virtual (pre-programmed by the experimenter).

This research offers an empirical framework for sociologists seeking to apply social theories into neurological studies.

Identifying effective coping strategies for historically oppressed racial groups.

The chapter is original for demonstrating the moderating effects of values on neural responses to exclusion for the first time and by offering a novel neurosociological framework.

The long-term development of a mobile gaming application (app) depends on its continued use by its users. The expectation–confirmation model of IS continuance was used as the basic framework, to which bi-dimensional consumption emotions were added to help better explain satisfaction judgment and continuance intention in the context of mobile gaming app use. The paper aims to discuss this issue.

The data were analyzed using structural equation models. The effects of positive consumption emotions and negative consumption emotions were examined, respectively, in Models 1 and 2. Competing models (Models 3 and 4) were also examined in order to compare the proposed model.

Both PE and NE have an effect on the satisfaction of mobile gaming app users and their continued usage intention, a finding that represents an important contribution to the extension of technology continuance theory. Comparison with the IS continuance model shows that the new model can explain significantly more variance in continuance intention.

Mobile gaming firms should pay attention to users’ consumption emotions, especially negative emotions. Some specific emotions involved in mobile gaming app use were identified, which could guide firms’ understanding of users’ emotions.

This study offers insight into the role of consumption emotions in forming continuance intentions toward mobile gaming app use in China, a topic that has not previously been investigated.

The paper aims to discuss the inverse heat conduction methodology in solution of a certain parameter identification problem. The problem itself concerns determination of the thermophysical properties of a thin layer coating by applying the laser flash apparatus.

The modelled laser flash diffusivity data from the three-layer sample investigation are used as input for the following parameter estimation procedure. Assuming known middle layer, i.e. substrate properties, the thermal diffusivity (TD) of the side layers’ material is determined. The estimation technique utilises the finite element method for numerical solution of the direct, 2D axisymmetric heat conduction problem.

The paper presents methodology developed for a three-layer sample studies and results of the estimation technique testing and evaluation based on simulated data. The multi-parametrical identification procedure results in identification of the out of plane thin layer material diffusivity from the inverse problem solution.

The presentation itself is limited to numerical simulation data, but it should be underlined that the flake graphite thermophysical parameters have been utilised in numerical tests.

The developed methodology is planned to be applied in detailed experimental studies of flake graphite.

In the course of a present study, a methodology of the thin-coating layer TD determination was developed. In spite of the fact that it has been developed for the graphite coating investigation, it was planned to be universal in application to any thin–thick composite structure study.

Premenstrual syndrome (PMS) can disrupt women’s work process, social activities and interpersonal communication and lead to a lower quality of life (QOL). This study aims to determine the effectiveness of happiness training based on Fordyce’s theory on QOL and the Positive and Negative Affect Schedule (PANAS) in women with PMS.

This randomized controlled trial was conducted on 100 women (intervention = 50, control = 50). The intervention group participated in eight 120-min sessions of training counseling based on Fordyce happiness training. The participants completed a sociodemographic questionnaire, the PANAS and the 36-Item Short Form Health Survey (SF-36). A general linear model was used to compare the mean scores of QOL and positive and negative affect after the intervention.

After the intervention, the mean scores of negative affect [MD = −6.12; 95% confidence interval (CI) = −12.10 to −1.49] and body pain (MD = −26.19; 95% CI = −38.63 to −13.72) were significantly lower in the intervention compared to the control group. Also, the mean scores of physical functioning (MD = 42.0; 95% CI = 16.37 to 67.64) and vitality (MD = 10.40; 95% CI = 4.86 to 15.39) were significantly higher in the intervention group compared to the controls.

Fordyce happiness training is recommended to be used in conjunction with other supportive and caregiving methods for women with PMS. Midwifes and nurses are the main source to give this training to women and can help them perform cognitive tasks, such as concentration, positive thinking and negative emotions.

This randomized controlled trial suggests Fordyce happiness training as a feasible and acceptable training program that can be beneficial in reducing negative affect in women with PMS.
