The study examines the value-relevance of reported financial information of fast-changing science-based companies and the incremental value-relevance of publicly available nonfinancial information. Based on a sample of independent cellular phone companies we find that on a stand-alone basis financial information (earnings book values and cash flows) appears largely irrelevant for valuation. However when combined with nonfinancial information these variables contribute to the explanation of stock prices and returns. Also the value- relevance of nonfinancial information overwhelms that of traditional financial indicators. Finally regarding investors' timely recognition of the implications of nonfinancial information we find that a key cellular nonfinancial growth measure -- POPS -- is positively associated with subsequent stock returns after controlling for various risk and growth measures. This may indicate either a systematic investor underreaction to nonfinancial information (market inefficiency) or that this nonfinancial measure proxies for risk.

The model of excellencism and perfectionism (MEP) theorizes that the attitude toward goals as characterized in excellencism is desirable over perfectionism. Using the self-determination theory (SDT), this study aims to investigate the varying effects of perfectionism and excellencism on work engagement and performance. The study used a time-lagged multi-phase, multi-source, and cross-sectional online survey to collect responses from 360 corporate employees of Indian companies in the services industry. The results indicate that while both perfectionism and excellencism entail pursuing high standards, they relate differently with performance and work engagement. Interestingly, excellencism and work engagement were significantly associated with performance (p < .001); however, perfectionism was insignificant (p = .989). Perfectionism strengthens work engagement (β = 0.112; p = .013), while excellencism has an insignificant effect (β = 0.035; p = .537). Work engagement fully mediates the perfectionism-performance relationship. This demonstrates that striving for excellence alone is sufficient to achieve positive performance, challenging the traditional belief that one must focus on perfection. Furthermore, perfectionism is positively associated with performance only when employees are engaged and have positive motivation toward work.

The increasing prominence of concepts such as Smart Production and Industrial Internet of Things (IIoT) within the context of Industry 4.0 has introduced a new set of requirements for the engineering of industrial systems, including support for dynamic environments, timeliness guarantees, support for heterogeneity, interoperability and reliability. These requirements are further exacerbated at the network level by the notable rise in the number and variety of devices involved. To stay competitive in this ever-changing industrial landscape while boosting productivity, it is vital to meet those requirements, combining established protocols with emerging technologies. Software-Defined Networking (SDN) is the forefront traffic management paradigm that offers flexibility for complex industrial networks, enabling efficient resource allocation and dynamic reconfiguration. Message Queuing Telemetry Transport (MQTT) is a low-overhead protocol of the application layer that is gaining popularity in the scope of the IoT and IIoT. However, its Quality-of-Service (QoS) policies do not support timeliness requirements. This article presents a framework that seamlessly integrates SDN and MQTT, enhancing network management flexibility while satisfying real-time requirements found in industrial environments. It leverages the User Properties of MQTTv5 to allow specifying real-time requirements. MQTT traffic is intercepted by a Network Manager that extracts real-time information and instructs an SDN controller to deploy corresponding network reservations. MQTT traffic across multiple edge networks is propagated by selected brokers using multicasting. Extensive experiments validate the proposed approach, demonstrating its superiority over MQTT and Direct Multicast-MQTT (DM-MQTT) DM-MQTT in latency reduction. A response time analysis, validated experimentally, emphasizes robust performance across metrics.
