The purpose of this chapter is to contextualize mixed findings in the self-complexity literature. Self-complexity (when individuals' identity meanings do not overlap) theoretically buffers negative outcomes associated with distressing experiences, like identity non-verification (perceptions that others see individuals differently than individuals see themselves). However, research on self-complexity overlooks the social context in which these processes occur. Here, the author argues that multiplexity (when individuals are connected in two or more role relationships) provides meaningful context that influences whether self-complexity functions as a buffer. This leads to two competing arguments: (1) multiplexity enhances the self-complexity buffering effect and (2) multiplexity undermines the self-complexity buffering effect.

Using egocentric network survey data from 314 US adults, the author ran four regression models (two for the friend identity, two for the coworker identity). These models test whether self-complexity moderates the effect of non-verification on distress when individuals do (or do not) have multiplex ties in which they are close friends with their coworkers.

Multiplex ties amplify the buffering effect of self-complexity when non-verification occurs in the coworker identity, but multiplex ties weaken the buffering effect of self-complexity when non-verification occurs in the friend identity.

This work supports the idea that the benefits associated with self-complexity are conditional on social context as well as identity context. Future research should consider these realities when examining how identity and buffering processes relate to wellbeing.

This work integrates social network analysis and identity theory to reconcile mixed findings in the literature on self-complexity.

A multiplex relation occurs when actors share different roles, actions, or affiliations that overlap in a relationship, such as co-workers who are also friends outside of work. Although multiplex relations are as varied as they are pervasive and often problematic, we know surprisingly little about when, under what circumstances, and exactly how overlapping ties affect social relations. Do they strengthen or weaken relationships? When do relationships become multiplex? How do they affect networks at large? In this chapter, we review notable studies that exist on this topic and suggest key questions and issues for future research. Our goal in particular is to suggest how exchange theory could contribute to these efforts.

The objective of this paper is to investigate approaches pertaining to the safe evacuation of occupants from multiplex facilities during fire emergencies.

The paper analyzes the published literature for the purpose of identifying the frequent causes of ignition in multiplex facilities and examining the set of factors that render multiplex facilities to be high‐risk facilities in fire emergences. The paper then describes the set of prescriptive international building regulations for the means of egress in public assembly facilities, as being the thresholds of the minimum safety levels that are acceptable to society; and presents a set of proposed guidelines for facility managers to observe in their day‐to‐day operation of multiplex facilities.

The paper has established that multiplex facilities are high‐risk buildings in fire emergencies. The role of facilities managers in the operation and maintenance stages of multiplex facilities has been discussed for the purposes of achieving safe evacuation of occupants and improved crowd management.

This paper provides for a better comprehension of the roles of design professional and facility managers involved in the design and operation of multiplex facilities in the provision and maintenance of adequate means of egress in such facilities.

Optical fibre multiplexed sensors are used to make measurements at multiple, discrete locations, usually by sending optical signals between each measurement location and a conveniently positioned optical interrogation instrument. It is rapidly becoming practical to construct multiplexed optical fibre sensor arrays based on in‐fibre Bragg gratings. A Bragg grating can be produced in an optical fibre by writing a periodic variation in the refractive index of the fibre’s core along the axis, using ultra‐violet light. Multiplexing applications will appear ranging from the small scale, with only a few sensors, up to very large scales with hundreds of sensors.

Globally a new wave of retailers are threatening the viability of many wholesalers, especially smaller more vulnerable wholesale distributors, as these new wave retailers aggressively compete for the business customer. To better understand this new form of competition, a theoretical model is developed from the organizational buyer behavior literature to explain the relative patronage preferences of business customers for wholesale‐distributors as a supply source versus two types of multiplex retailers ‐ warehouse home centers and office supply superstores. The model, previously untested in the business‐to‐business literature, postulates that business buyers select supply sources based on a “total value of purchasing” criterion. The total value is a function of price and the perceived costs associated with credit services, product‐acquisition services, and risk‐reduction services. The model is empirically tested in both an office supply superstore and warehouse home center setting with survey research conducted in six cities in the USA. Substantial empirical support, with the exception of the credit component, is obtained for the model.

The purpose of this paper is to explore the effect of “multiplex” (multiple overlapping) networks and leadership on group performance in a higher education setting.

Using a combination of social network analysis and interviews, the authors employ a case study approach to map the connections between academic group members. This paper analyses the relationship between this mapping and academic performance.

The authors identified two dimensions which influence group effectiveness: multiplex networks and distributed–coordinated leadership. Where networks are built across tasks, inter-relationships develop that lead to greater group performance.

Where group members create a dense hive of interconnectivity and are active across all group tasks, and also informally, this increases the opportunity for knowledge sharing. When this is similarly experienced by a majority of group members, there is positive reinforcement, resulting in greater group effectiveness.

This paper highlights the importance of the richness of formal ties in knowledge-intensive settings. This paper is the first to differentiate between formal connections between colleagues related to different tasks within their role. This suggests that dense configurations of informal ties are insufficient; they must be coupled with strong ties around formal activity and demonstrative leadership.

The social and cultural duality perspective suggests dual ordering of interpersonal ties and cultural similarities. Studies to date primarily focus on cultural similarities in interpersonal dyads driven by principles such as homophily and contagion. We aim to extend these principles for sociocultural networks and investigate potentially competing micro-principles that generate these networks, taking into account not only direct dyadic overlap between interpersonal ties and cultural structures, but also the indirect interplay between the social and the cultural.

The empirical analysis utilizes social and semantic network data gathered through ethnographic studies of five creative organizations around Europe. We apply exponential random graph models (ERGMs) for multiplex networks to model the simultaneous operation of several generative principles of sociocultural structuring yielding multiplex dyads and triads that combine interpersonal ties with meaning sharing links.

The results suggest that in addition to the direct overlap of shared meanings and interpersonal ties, sociocultural structure formation is also affected by extra-dyadic links. Namely, expressive interpersonal ties with common third persons condition meaning sharing between individuals, while meaning sharing with common alters leads to interpersonal collaborations. Beyond dyads, the dual ordering of the social and the cultural thus operates as asymmetrical with regard to different types of interpersonal ties.

The paper shows that in addition to direct dyadic overlap, network ties with third parties play an important role for the co-constitution of the social and the cultural. Moreover, we highlight that the concept of network multiplexity can be extended beyond social networks to investigate competing micro-principles guiding the interplay of social and cultural structures.

The purpose of this paper is to evaluate the reliability and signature reliability of solar panel k-out-of-n-multiplex system with the help of universal generating function.

Energy scarcity and global warming issues have become important concerns for humanity in recent decades. To solve these problems, various nations work for renewable energy sources (RESs), including sun, breeze, geothermal, wave, radioactive and biofuels. Solar energy is absorbed by solar panels, referred to as photovoltaic panels, which then transform it into electricity that can be used to power buildings or residences. Remote places can be supplied with electricity using these panels. Solar energy is often generated using a solar panel that is connected to an inverter for power supply. As a result, a converter reliability evaluation is frequently required. This paper presents a study on the reliability analysis of k-out-of-n systems with heterogeneous components. In this research, the universal generating function methodology is used to identify the reliability function and signature reliability of the solar array components. This method is commonly used to assess the tail signature and Barlow-Proschan index with independent and identically distributed components.

The Barlow-Proschan index, tail signature, signature, expected lifetime, expected cost and minimal signature of independent identically distributed are all computed.

This is the first study of solar panel k-out-of-n-multiplex systems to examine the signature reliability with the help of universal generating function techniques with various measures.

This study investigates the role of collaborative spaces as organizational support for internal innovation through cross-functional teams and for open innovation with external stakeholders. In particular, the study focuses on collaborative spaces as tools for multiplex (i.e., simultaneous internal and external boundary management in innovation projects).

The authors conducted a qualitative study in a multi-divisional organization that set up in its headquarters a collaborative space for collaborative product development. Data were collected through semi-structured interviews and participant observations.

Findings highlight that the relation between expectations and experiences about the collaborative space impact on employees' ability to perform boundary work inside and outside the organization. In addition to the collaborative space's affording role for expectations about hands-on collaborative innovation (space as laboratory), the study also highlights a set of collaboration constraints. These latter are generated by perceived boundary configurations (i.e. degree of boundary permeability and infrastructure in internal and external collaborations) and by discrepancies between expectations (space as laboratory) and actual collaboration experiences in the space (i.e. space as maze, cloister, showcase and silo). We show that space-generated constraints slow down internal and external boundary work for innovation and generate a trade-off between them.

Using the process-based perspective of boundary work, the paper connects studies on cross-functional teaming and open innovation through the concept of “multiplex boundary work.” It also contributes to the literature on boundary work by showing the challenges of using collaborative spaces as organizational support tools for multiplex boundary spanning.

The terms multiplexing and integration are being used with increasing frequency in the context of building services installations and management systems. In this article we somewhat cautiously attempt to define the processes involved, analyse their relevance to services design and management, and look to the future. This does not purport to be the definitive scientific appraisal of all the technical matters involved. However, it is intended as a way of setting the scene which we hope to follow up in later issues of Facilities with more detailed discussion of the complex issues involved.
