Exploring the Role of the Family CEO in Firm Innovation: A Capability-Based Perspective

Family firms are ubiquitous around the world. Family involvement in family businesses gives rise to unique features that not only make family firms behave distinctively from their nonamily counterparts but also lead to great variations among such firms. From an innovation perspective, while family firms are regarded as conservative businesses that lack an innovation spirit in some studies, others recognize family firms as key economic drivers demonstrate entrepreneurial spirit. This dissertation is an attempt to advance the understanding of family firm innovation heterogeneity by focusing on the role of family CEOs. In particular, this research explores what idiosyncratic resources and capabilities are generated from family management, specifically when a family member holds the CEO position. Employing a capability-based perspective of firm innovation, this research posits that the impact of a family CEO on firm innovation is twoold. Family CEOs have a direct impact on firm innovation due to the distinctive resources possessed and the unique goals pursued. Family CEOs also have an indirect impact on firm innovation via the configuration and orchestration of other top management team (TMT) members’ competencies, which manifests as high-order, idiosyncratic managerial capabilities. Therefore, superior or inferior family firm innovation is the result of both TMT members’ unique competencies acquired and developed by family firms as well as family CEOs’ idiosyncratic managerial capabilities. A randomly selected sample of 250 high-technology firms was used for the empirical tests. Findings suggest that family CEOs have a direct impact on firm innovation input and output and that family CEOs configure and orchestrate TMT resources distinctively compared to their professional counterparts. The results reveal theoretical implications for both family business and firm innovation and offer practical implications for leaders of family firms

Influence of SiO2@PMHS on the Water Absorption of Cement Mortar as a Surface Treatment Agent

In this paper, the core–shell structured SiO2@PMHS hybrid nanoparticles were synthesized with tetraethoxysilane (TEOS) and polymethylhydrosiloxane (PMHS). And SiO2@PMHS core–shell nanoparticles were first used as a surface treatment agent for cement-based materials. The influence of SiO2@PMHS nanoparticles on the water absorption of hardened cement mortar with water-to-cement ratio of 0.6 was investigated. Results showed that the water absorption of cement mortar treated with SiO2@PMHS nanoparticles was decreased by 93.47% in comparison to the control sample

Fluoroquinolone Resistance in <i>Salmonella</i>: Mechanisms, Fitness, and Virulence

Fluoroquinolones are highly effective broad-spectrum antibiotics usually used for the treatment of human and animal infections, including salmonellosis. Fluoroquinolones act against Salmonella by inhibiting their DNA replication. However, several zoonotic serotypes of Salmonella have developed resistance or are less susceptible to fluoroquinolones. Salmonella presents its resistance by substituting amino acids within the topoisomerase subunits, overexpression of multidrug efflux pumps, or decreasing the expression of outer membrane porins. The resistance level is further increased with the plasmid-mediated quinolone resistance genes which could horizontally transfer the resistance from strain to strain. The development of resistance in Salmonella shows that it is a multifactorial process and the acquisition of fluoroquinolone resistance might have significant influences on the bacterial fitness and virulence. Due to the high level resistance against fluoroquinolones that has been observed in Salmonella, care needs to be taken to avoid misuse and overuse of this important class of antibiotics to minimize the occurrence and dissemination of resistance

The Synergistic Effect of Nano-Silica with Slag on Frost Resistance of Concrete

The frost resistance of concrete is one of the most important factors for its durability. Supplementary cementitious materials could effectively improve the frost resistance of concrete. On this basis, the synergistic effect of nano-silica (NS) with slag on the frost resistance of concrete is better than the single, which was investigated. Nano-silica and slag were employed as a partial substitute of cement. The effect of these on the related indexes, including the mass loss, relative dynamic elastic modulus and porosity of concrete were measured after specified number of freeze and thaw cycles. Results show that the frost resistance of nano-silica modified concrete was obviously improved. The mass loss of control concrete was 2.5 % after 300 freeze-thaw cycles while that of the nano-silica modified concrete was as low as 1%. Further, the anti-freeze durability factor can reach up to 89.55% for the nano-silica modified concrete. The reasons are that the activity and nucleation effects of nano-silica accelerate the hydration of cement and the filling effect leads to more compact matrix. All of these made concrete better frost resistant. This was also proven by the porosity analysis. When the nano-silica was added, the total porosity of nano-silica modified concrete decreased from 14.57 % to 11.39 % compared with the control concrete. So, the synergistic effect of nanosilica with slag can enhance the frost resistance of concrete and improve its durability

Role of the ortho-bridge system in the length unstable subtrochanteric femur fracture in school going children: a retrospective clinical study of 19 cases

BackgroundTreating subtrochanteric femur fractures in pediatric patients remains challenging, and an optimal fixation device has yet to be established. This study aimed to asess the clinical and radiological outcomes of Ortho-Bridge System (OBS) treatment for length-unstable subtrochanteric femur fractures in children aged 5–16 years.MethodsWe conducted a retrospective review of pediatric patients with subtrochanteric femur fractures treated with OBS between January 2018 and December 2021. The study included 19 children (12 boys, 7 girls) with an average age of 10.4 ± 2.6 years. Two of the patients had pathological fractures associated with aneurysmal bone cyst. Demographic information, mechanism of accident, fracture type, associated neurovascular injuries, surgical duration and blood loss, were collected from the hospital database. Time to union and postoperative complications were recorded. Clinical and radiological outcomes were assessed using the Harris scoring system at the latest follow-up.ResultsInjuries resulted from vehicle accidents in 10 patients (52.6%), falls over 3 meters in height in 3 patients (15.8%), and sports-related injuries in 6 patients (31.6%). The average patient weight was 41.5 kg (range: 21–78). Of the fractures, 14 (73.7%) were complex, and 5 (26.3%) were spiral. The average surgical duration was 111 min (range: 90–180), and the average surgical blood loss was 134 ml (range: 70–300). The mean time to union was 12.7 weeks (range: 8–16). No cases of infection, malunion, implant failure, or femoral head osteonecrosis were reported. Leg length discrepancy of 10 mm was observed in one patient. All patients achieved excellent results according to the Harris scoring system.ConclusionThis study suggests that the OBS may serve as an effective alternative fixation option for managing length-unstable subtrochanteric femur fractures in school-aged children

Intelligent Multi-Modal Sensing-Communication Integration: Synesthesia of Machines

In the era of sixth-generation (6G) wireless communications, integrated sensing and communications (ISAC) is recognized as a promising solution to upgrade the physical system by endowing wireless communications with sensing capability. Existing ISAC is mainly oriented to static scenarios with radio-frequency (RF) sensors being the primary participants, thus lacking a comprehensive environment feature characterization and facing a severe performance bottleneck in dynamic environments. To date, extensive surveys on ISAC have been conducted but are limited to summarizing RF-based radar sensing. Currently, some research efforts have been devoted to exploring multi-modal sensing-communication integration but still lack a comprehensive review. Therefore, we generalize the concept of ISAC inspired by human synesthesia to establish a unified framework of intelligent multi-modal sensing-communication integration and provide a comprehensive review under such a framework in this paper. The so-termed Synesthesia of Machines (SoM) gives the clearest cognition of such intelligent integration and details its paradigm for the first time. We commence by justifying the necessity of the new paradigm. Subsequently, we offer a definition of SoM and zoom into the detailed paradigm, which is summarized as three operation modes. To facilitate SoM research, we overview the prerequisite of SoM research, i.e., mixed multi-modal (MMM) datasets. Then, we introduce the mapping relationships between multi-modal sensing and communications. Afterward, we cover the technological review on SoM-enhance-based and SoM-concert-based applications. To corroborate the superiority of SoM, we also present simulation results related to dual-function waveform and predictive beamforming design. Finally, we propose some potential directions to inspire future research efforts.Comment: This paper has been accepted by IEEE Communications Surveys & Tutorial
