Abstract
Purpose
In this work, the authors are interested in the notion of vector valued and set valued Pettis integrable pramarts. The notion of pramart is more general than that of martingale. Every martingale is a pramart, but the converse is not generally true.
Design/methodology/approach
In this work, the authors present several properties and convergence theorems for Pettis integrable pramarts with convex weakly compact values in a separable Banach space.
Findings
The existence of the conditional expectation of Pettis integrable mutifunctions indexed by bounded stopping times is provided. The authors prove the almost sure convergence in Mosco and linear topologies of Pettis integrable pramarts with values in (cwk(E)) the family of convex weakly compact subsets of a separable Banach space.
Originality/value
The purpose of the present paper is to present new properties and various new convergence results for convex weakly compact valued Pettis integrable pramarts in Banach space.

Abstract
Two studies in the context of English‐French relations in Québec suggest that individuals who strongly identify with a group derive the individual‐level costs and benefits that drive expectancy‐value processes (rational decision‐making) from group‐level costs and benefits. In Study 1, high identifiers linked group‐ and individual‐level outcomes of conflict choices whereas low identifiers did not. Group‐level expectancy‐value processes, in Study 2, mediated the relationship between social identity and perceptions that collective action benefits the individual actor and between social identity and intentions to act. These findings suggest the rational underpinnings of identity‐driven political behavior, a relationship sometimes obscured in intergroup theory that focuses on cognitive processes of self‐stereotyping. But the results also challenge the view that individuals' cost‐benefit analyses are independent of identity processes. The findings suggest the importance of modeling the relationship of group and individual levels of expectancy‐value processes as both hierarchical and contingent on social identity processes.

Abstract
THE experience gained with the previous models of the “Bluebird” type has enabled the Bluebird IV to be produced embodying all the requirements essential in a light aeroplane for private and club flying. This experience indicated that the policy of side‐by‐side seating in preference to the more usual tandem arrangement was fully justified, and, although previously it had been considered that such an arrangement was necessarily detrimental to performance owing to the wider fuselage, a considerable amount of investigation proved that a fuselage could be designed maintaining the requisite width, but of such a “body form” as to make this loss of performance practically non‐existent. As a result of these investigations it was decided to develop the “Bluebird” both acrodynamically and structurally, and the actual product by its flight tests confirms the theoretical and model investigation, the side‐by‐side Bluebird IV having a performance at least equal to the performance of the best tandem light aeroplane of the same class and the same engine.

Abstract
Purpose
This paper aims to clarify the effect of attitudinal ambivalence on resistance to anti-smoking persuasion through information processing styles. It was hypothesized that a high smoker’s ambivalence, induced by an anti-smoking persuasive message, triggers among smokers both a reflective and a non-reflective information processing. In turn, both the information processing styles were supposed to be predictors of the resistance to anti-smoking persuasion.
Design/methodology/approach
An experiment and a survey were conducted on a random sample of 347 smokers in this regard.
Findings
The findings indicated that smokers feel ambivalent toward anti-smoking messages in print ads and tend to process them both analytically and superficially. Also, it seems that only the analytical processing triggers resistance to anti-smoking persuasion.
Originality/value
The author reports on the importance of attitudinal ambivalence and information processing in the resistance to anti-smoking persuasion process. The paper should be of interest to readers in the areas of health communication and social marketing. This work seems to be important to the extent that few works have highlighted the causal and linear effect of a persuasive anti-smoking message on smokers’ ambivalence, information processing and resistance to persuasion. The findings in this paper seem interesting insofar, as they show the importance of the negative emotional appeal in the ambivalence, analytical information processing and resistance triggering.

Abstract
Purpose
This paper aims to attempt to develop an integrative theoretical framework that approaches global industrial marketing from a managerial cognition perspective.
Design/methodology/approach
Drawing from the managerial cognition research, business strategy research, and international business research, this paper develops a theoretical framework that is relevant to global industrial marketing.
Findings
Global industrial marketing research has much to gain from the managerial cognition literature. The framework developed in this article presents relevant managerial cognition variables, their individual and firm level antecedents, and desirable outcomes.
Research limitations/implications
The framework presented in this paper provides strong theoretical foundation for further theory development in global industrial marketing research and managerial cognition research. However, given the conceptual nature of our research, empirical scrutiny and further conceptual and empirical research are required.
Originality/value
Given the growing importance of global industrial marketing, the authors hope that this article provides a theoretical foundation for future research. For practitioners, the framework provides a useful starting point for evaluating managerial cognition in their firms and effective usage of the managerial cognition concept.

Abstract
Purpose
Diagnosing psychiatric disorders (PD) in adults with Intellectual Disability (ID) presents several issues and need specific skills and tools. The purpose of this paper is to provide a detailed description of the current status of art through a systematic mapping of the literature.
Design/methodology/approach
The authors reviewed the international literature on the basis of the following questions: what are the issues in the psychiatric diagnostic process for adults with ID? What methods and procedures have been used for psychiatric assessment in ID? To date, is it possible to identify some most effective procedures?
Findings
The analysis of the literature indicates that main issues of the psychiatric diagnostic process in adults with ID are the following: identification of psychiatric symptoms, behavioural equivalents, diagnostic criteria, setting, source of information, screening, and diagnostic tools. The evidence base is only emerging and although many relevant achievements have been reached in the last two decades, no definitive guideline has been produced. Most recent acquisition also allowed to identify some assessment procedures that are currently considered the most effective. Individualised assessment remains the best way to meet the needs of this heterogeneous and variable patient group.
Originality/value
This paper offers a comprehensive and updated description of current achievements and issues towards the assessment of PD in people with ID.

Abstract
Purpose
Wearable health information systems (IS) open up a new era for personal health self-management, and bring about disruptive changes to individual lives. However, prior studies on IS post-adoptive behavior primarily focused on either continuance or discontinuance, neglecting the mutual transformation process between IS usage and rejection behavior. This behavior is expressed as intermittent discontinuance in the current study. By revising and extending the expectation-disconfirmation model, the purpose of this paper is to understand the factors affecting information system intermittent discontinuance in the context of wearable eHealth.
Design/methodology/approach
This study proposes a revised expectation-disconfirmation model by incorporating four new theoretical constructs, i.e. neutral disconfirmation, attitudinal ambivalence, neutral satisfaction, and intermittent discontinuance. An online survey was used to validate the research model, and 428 wearable health device users were recruited in this study.
Findings
Empirical results demonstrate that neutral disconfirmation exerts positive effects on neutral satisfaction and attitudinal ambivalence, both of which further have positive effects on intermittent discontinuance. In addition, attitudinal ambivalence also has a positive and significant effect on neutral satisfaction.
Originality/value
This study extends the current understanding on IS post-adoption usage behavior by introducing a new concept, i.e., intermittent discontinuance. In particular, post-adoption usage behavior is viewed as a dynamic process within a changing environment in this study. Some unique features specific to intermittent discontinuance are also identified. In this regard, neutral and conflicting constructs further add new values to IS adoption and diffusion literature. In addition, the integration of eHealth and wearable devices provides a fruitful research context for future research, and this study represents one of the first attempts to empirically explore the intermittent usage problems encountered within this emerging phenomenon.

Abstract
Purpose
This study aims to evaluate the vitality of source, receiver and message factors on credibility assessment of online hotel reviews. Further, the current study determines the effects of perceived credibility of online reviews (PCOR) on hotel booking intentions (HBI).
Design/methodology/approach
The current study performs reliability analysis to determine the internal consistency of the measurement scales and to ensure the uni-dimensionality of the measurement scales the present study performs exploratory factor analysis. Further, the present study performs structural equation modeling to identify the relationships between the variables.
Findings
Two-sided online reviews have a more significant positive impact on PCOR as compared to the effects of receiver, review quality, review consistency and negative-sided online reviews.
Originality/value
This is one of the first study that analyses the impact of source, receiver and message on PCOR. Moreover, the present study offered theoretical justification behind the factors that affect the authenticity of online hotel reviews and its effects on HBI.

Abstract
The changing role of technology in the virtual workplace has been accompanied by a proliferation of research activity focusing initially on the technical aspects and, more recently, on the social and political aspects of the diffusion process, including power and politics. This paper builds on the work of Kling and Markus on power and politics in IT, extending it to e‐mail and more specifically, to the use of e‐mail for petty tyranny. Reviews the literature on petty tyranny and its implications to IT and e‐mail. Presents a case study in which e‐mail was used by a department chair to manipulate, control, and coerce employees. The discussion links the events in the case with the literature on petty tyranny. In conclusion, demonstrates that e‐mail features make it amenable to political abuse and elaborates on the more general, theoretical, practical and ethical implications from this research.

Abstract
Purpose
The purpose of this study is to examine potential predictors and moderating relationships involving one type of organizational cynicism – cynicism about organizational transformation (CAOC).
Design/methodology/approach
A total of 137 subjects participated in this study. The participants had been in their current positions at work for an average of 4.77 years and had been with their current organization an average of 7.28 years. CAOC was measured using the 12-item scale (α = 0.86) from Wanous et al.’s (2000) study. The response scale had five points ranging from “strongly disagree” to “strongly agree.”
Findings
CAOC and negative affectivity were positively correlated, thus supporting H1. H2 was not supported, i.e. subjective change was not related to CAOC, and objective change was actually correlated negatively with CAOC. H3 was not supported, i.e. individuals with a higher organizational commitment will not have a less positive relationship between CAOC and organizational transformation (subjective and objective) than individuals with lower organizational commitment. H4 was not supported, i.e. individuals who perceive a higher degree of petty tyranny will not have a stronger relationship between CAOC and organizational transformation (subjective and objective) than individuals who perceive a lower degree of petty tyranny. H5 was not supported, i.e. individuals who perceive a higher degree of perceived organizational support (POS) will not have a weaker relationship between CAOC and organizational transformation (subjective and objective) than individuals who perceive a lower degree of POS.
Originality/value
The intent of the present study is to examine potential causes of CAOC and potential moderators of the relationships between those antecedents and CAOC. In particular, two variables are proposed as antecedents (negative affectivity with past organizational transformations) and three as moderators (organizational commitment, petty tyranny by supervisors and POS).
