Abstract
Purpose
Existing research on how professionals manage after-hours connectivity to work has been dominated by studies on the strategies/practices individuals develop. In these studies, mobile technology is perceived as a tool or an enabler that supports otherwise human-centric connectivity decisions. This view sees technology as separate or external to the organisation, missing out on its nuanced role in shaping connectivity decisions. Our study aims to bring technology back into the sociomaterially imbricated context of connectivity and to unpack its parameters.
Design/methodology/approach
Drawing on data collected from documents and semi-structured interviews, we adopt the framework of “sociomaterial imbrications” (Leonardi, 2011) to understand the social and material parameters that influence connectivity management practices at two different academic institutions in Saudi Arabia.
Findings
The study identifies a set of social and material parameters (organisational, individual, technological and situational) that imbricate to shape, collectively and not individually, professionals’ connectivity management practices. Connectivity decisions to change practice (such as decisions of where, when or why to connect) or technology (how to connect) are not as distinct as they appear but originate from, and are founded on, imbricated sociomaterial parameters. Our study further suggests that connectivity decisions are shaped by individuals’ perceptions of sociomaterial imbrications, but decisions are not solely idiosyncratic. The context within which connectivity decisions are taken influences the type of decisions made.
Originality/value
Connectivity management emerged from sociomaterial imbrications within a context constitutive of four interacting parameters: organisational, technological, situational and individual. Decisions around the “how” and the “what” of connectivity – i.e. the practice of connectivity and its underpinning technology – originate from how people perceive sociomaterial imbrications as enabling or constraining within a context. Individual perceptions account for changes in practice and in technology, but the context they find themselves in is also important. For instance, we show that professionals may perceive a certain technology as affording, but eventually they may use another technology for communications due to social norms.

Abstract
We develop a Bayesian approach for modeling brain activation and connectivity from functional magnetic resonance image (fMRI) data. Our approach simultaneously estimates local hemodynamic response functions (HRFs) and activation parameters, as well as global effective and functional connectivity parameters. Existing methods assume identical HRFs across brain regions, which may lead to erroneous conclusions in inferring activation and connectivity patterns. Our approach addresses this limitation by estimating region-specific HRFs. Additionally, it enables neuroscientists to compare effective connectivity networks for different experimental conditions. Furthermore, the use of spike and slab priors on the connectivity parameters allows us to directly select significant effective connectivities in a given network.
We include a simulation study that demonstrates that, compared to the standard generalized linear model (GLM) approach, our model generally has higher power and lower type I error and bias than the GLM approach, and it also has the ability to capture condition-specific connectivities. We applied our approach to a dataset from a stroke study and found different effective connectivity patterns for task and rest conditions in certain brain regions of interest (ROIs).

Abstract
The connectivity provided by full-service network carriers under the umbrella of airline alliances is increasingly challenged by the services of Middle Eastern airlines via their own hubs, and the rise of new passenger strategies like self-connectivity. While these two developments can potentially benefit consumers with more services and lower fares, the rise of Middle East carriers has been met with opposition by EU and US airlines that call for increased protectionism. In addition, only a few airports in the world actively support self-connections. In this context, this study aims to investigate (1) the markets in which Middle East carriers exert a stronger dominance in terms of the number of passenger connections, (2) whether EU, US, or Asian hubs provide a competitive quality of connectivity in terms of travel time, and (3) whether a significant potential for self-connections is hidden at major airports worldwide. To that end, several datasets of passenger bookings (MIDT), airline schedules, and minimum connecting times between 2012 and 2015 are combined in a connections-building methodology that delivers six market-specific airport connectivity indicators for our benchmarking exercise. Our findings show that although European and some Asian hubs have lost traffic in global markets, they remain competitive from a quality perspective. US hubs have maintained their market share and competitive position. Finally, we identify the airports and airlines with the highest potential to provide self-connecting travel options, which can become an attractive new source of revenue for the parties involved.

Abstract
Purpose
This study develops and validates a theoretical model of real-time mobile connectivity, examining how employees' perceptions of their relationship with supervisors influence their emotional experiences. Through quasi-experiments, the authors investigate the behavioral patterns and emotional responses associated with real-time mobile connectivity in organizations, with a focus on messaging apps that indicate message read status. Specifically, they explore how supervisors' attentiveness or inattentiveness in mobile connectivity impacts emotional ambivalence (anxiety and pride) among subordinates. Additionally, they examine the downstream effects of this emotional ambivalence on employees' workplace thriving and job performance across various dimensions.
Design/methodology/approach
To address the paradox of real-time mobile connectivity, a quasi-experimental design involving 320 team members from 46 teams was implemented. Multi-level structural equation modeling was employed to analyze within-person variance and evaluate the proposed hypotheses.
Findings
The findings indicate that employees who do not receive timely indications from their supervisors are more likely to experience elevated levels of anxiety, while those who receive prompt indications experience a sense of pride. Moreover, the indirect effects of the real-time mobile connectivity paradox on employee performance, mediated by anxiety (negatively) and pride (positively), are fully explained through workplace thriving.
Research limitations/implications
This study provides insights into the emotional ambivalence experienced in the workplace due to real-time mobile connectivity, highlighting its implications for organizational competitiveness. Integrating resource conservation theory and cognitive appraisal theory of emotion, the study explores the mediating role of workplace thriving and the impact on employee performance through pride and anxiety. Generalizability requires considering organizational settings and cultural contexts while acknowledging limitations such as a focus on messaging apps and specific samples. Future research should explore these dynamics in diverse contexts and identify additional factors influencing the relationship between real-time mobile connectivity and employee outcomes.
Practical implications
This study provides valuable insights for managers regarding the significance of message indications, as their attentiveness can elicit emotional reactions from employees that subsequently impact workplace thriving and job performance.
Originality/value
This study pioneers the exploration of the paradox of real-time mobile connectivity in the workplace, uncovering the discrete emotions experienced by employees. Furthermore, it elucidates the subsequent opposing effects on workplace thriving and job performance, contributing to the existing literature and knowledge in this area.

Abstract
Purpose
This study aims to identify the characteristics of the maritime shipping network in Northeast Asia as well as compare the level of port connectivity among these container ports in the region. In addition, this study analyses the change in role and position of 20 ports in the region by clustering these ports based on connectivity index and container throughput and route index.
Design/methodology/approach
This study employs Social Network Analysis (SNA) to delineate the international connectivity of major container ports in Northeast Asia. Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) is used to identify each port's connectivity index and container throughput index, and the resulting indexes are employed as the basis to cluster 20 major ports by fuzzy C-mean (FCM).
Findings
The results revealed that Northeast Asia is a highly connected maritime shipping network with the domination of Shanghai, Shenzhen, Hong Kong and Busan. Furthermore, both container throughput and connectivity in almost all container ports in the region have decreased significantly due to the coronavirus disease 2019 (COVID-19) pandemic. The rapid growth of Shenzhen and Ningbo has allowed them to join Cluster 1 with Shanghai while maintaining high connectivity, yet decreasing container throughput has pushed Busan down to Cluster 2.
Originality/value
The originality of this study is to combine indexes of SNA into connectivity index reflecting characteristics of the maritime shipping network in Northeast Asia and categorize 20 major ports by FCM.

Abstract
Purpose
Credibility concerns regarding integrated reports can harm the intended decrease of information asymmetry between a firm and its investors. Therefore, it is crucial to examine whether voluntary third-party assurance enhances the credibility of integrated reports and, thus, decreases information asymmetry. Furthermore, this study aims to investigate the interaction effect between assurance quality and the disclosed connectivity of the capitals, a distinguishing feature of integrated reports.
Design/methodology/approach
Content analysis is performed of the 176 assurance statements included in the 269 integrated reports of Forbes Global 2000 firms disclosed from 2013 to 2015 and the 269 integrated reports themselves. Regression analyzes are applied to examine the associations between assurance, the disclosed connectivity of the capitals and information asymmetry.
Findings
The presence of an assurance statement in an integrated report significantly decreases information asymmetry. Surprisingly, assurance quality is not significantly associated with information asymmetry. However, an interaction analysis reveals that combining high assurance quality with high disclosed connectivity of the capitals allows a significant decrease in information asymmetry.
Research limitations/implications
The paper demonstrates that the connectivity of the capitals of integrated reports and assurance quality are connected and together are associated with information asymmetry.
Practical implications
The results imply, both for report preparers and standard setters, that assurance quality is advantageous only when combined with disclosed connectivity of the capitals.
Social implications
More information on non-financial information measured by the connectivity of the capitals of integrated reporting has an interaction effect together with assurance quality on information asymmetry.
Originality/value
This paper builds on a unique data set derived from the contents of integrated reports and accompanying assurance statements. Furthermore, it extends the integrated reporting literature by investigating the interaction between assurance quality and the disclosed connectivity of the capitals, which had not previously been examined in combination.

Abstract
Purpose
Given the reality of expectations of constant connectivity with work anytime, anywhere, this paper aims to investigate the gendered implications of these new expectations in the workplace focusing on the gender gap in work connectivity as well as the reasons behind it.
Design/methodology/approach
This paper is based on a large cross-national mixed methods study, using a quantitative survey within one multinational technology company (N = 7,256) and 69 in-depth interviews with female employees from five different countries all employed by the case study organization, exploring the extent and reasons behind the gender gap in work connectivity.
Findings
New communication technologies enable us to work temporally and spatially flexibly by providing us the opportunity for constant work connectivity from anywhere, anytime. This paper finds that women across a diverse set of cultural backgrounds reject the possibility for work connectivity significantly more often than their male peers leading to a gender gap in connectivity and it brings to the fore how and why women negotiate their level of connectivity as they do.
Originality/value
This study contributes to the existing work-family-balance and gender workplace study literatures by statistically and qualitatively expanding our knowledge on the gender gap in work connectivity across multiple countries and cultural contexts and by dismantling a further mechanism that leads to the glass ceiling.

Abstract
Purpose
Integrated reporting (IR) aims to provide disclosures of the connectivity of non-financial and financial value creation aspects. These disclosures are defined as the disclosed connectivity of the capitals resulting from integrated thinking. This paper aims to investigate the extent of disclosed connectivity of the capitals in integrated reports and its underlying managerial discretion by drawing on economic-based theories.
Design/methodology/approach
Regression analyses are applied to examine the associations between economic firm-level characteristics and the extent of disclosed connectivity of the capitals. The analyses are based on a content analysis of 169 integrated reports disclosed in 2013 and 2014 by Forbes Global 2000 companies.
Findings
This paper finds high heterogeneity in the extent of disclosed connectivity of the capitals in current IR practice. This heterogeneity is related to drivers arising from economic-based theories. Firms’ non-financial and financial performance and the importance of strategic shareholders and debt providers are positively associated with the extent of disclosed connectivity of the capitals. The complexity of the business model and a highly competitive environment are negatively associated with the extent of disclosed connectivity of the capitals.
Research limitations/implications
This paper extends qualitative IR studies on the disclosed connectivity of the capitals by quantitative results from a content analysis for a cross-sectional and global sample. Additionally, this study adds to prior IR literature on the drivers of the binary decision to disclose an integrated report by focusing on the extent of disclosed connectivity of the capitals.
Practical implications
For report preparers, users and standard setters, the results reveal that perceived cost-benefit considerations (signaling vs. direct and proprietary costs) may explain managerial discretion regarding the connectivity of the capitals within integrated reports.
Social implications
This paper examines integrated reports, which are intended to inform providers of financial capital and other stakeholders about the connectivity of the six capitals of the IR framework.
Originality/value
This paper develops a metric disclosure measure of the extent of disclosed connectivity of the capitals. It provides initial evidence of how the IR framework’s focus on this key characteristic is realized in disclosure practice. Concerns about competitive disadvantages and preparation costs limit this key characteristic of integrated reports.

Abstract
Purpose
In today’s aging world online communication is often viewed as a means to enhance social connectivity, and therefore well-being, of older adults. However, previous research on the influence of online communication on social connectivity largely disregards older adults, yields conflicting results and fails to assess the – debatable − causal direction of relationship. The purpose of this paper is to overcome these issues by developing four hypotheses related to who uses what, how, with whom.
Design/methodology/approach
The authors use a panel data study to test the hypotheses, including 302 older adults. Response rates are between 62 and 75 percent.
Findings
The authors find, first, that older adults differentiate between social connectivity with other village members, i.e., village connectivity, and connectivity with friends. Second, the impact of online communication varies among these two types of social connectivity. Where e-mail use has a negative impact on village connectivity, it does not affect connectivity with friends. Facebook use on the other hand has a negative impact on connectivity with friends, but not on village connectivity. The negative effects were not found among those older adults that were already well-connected on forehand, indicating a buffer effect.
Practical/implications
Policy makers’ implementing online communication tools to strengthen social connectivity of older adults, may want to carefully select tools based on the type of connectivity they aim to enhance. Impact needs to be monitored.
Originality/value
The authors contribute by analyzing how characteristics of online communication tools, i.e., information richness and privacy protection, as well as social connectivity, i.e., geographical proximity and emotional closeness jointly shape older adults’ social connectivity.
