    Purpose This study examines the direct effect of conscious leadership on organizational culture in small and medium-sized enterprises (SMEs) and tests whether higher purpose mediates this relationship, thereby advancing understanding of the micro-to-meso translation processes within conscious capitalism. Design/methodology/approach A cross-sectional survey of 115 Mexican SMEs was conducted. Data from senior executives were analyzed using partial least squares structural equation modeling (PLS SEM). Mediation was tested via bootstrapping with 5,000 resamples, and robustness checks addressed common method bias and predictive validity. Findings Conscious leadership has a strong direct effect on conscious culture (β = 0.512, p < 0.001). Higher purpose partially mediates this relationship (indirect effect β = 0.198, p = 0.007), revealing complementary behavioral and sensegiving pathways that together explain 55.1% of the variance in conscious culture. Practical implications SME leaders can embed higher purpose through purpose-based decision checklists, purpose-linked KPIs and stakeholder scorecards tracking safety, decent work and customer trust. Leadership development should train owner-managers as meaning makers skilled in sensegiving. At the policy level, existing SME training programs and public financing schemes could incorporate purpose-articulation modules at low cost, embedding ethical reflection into established support mechanisms without significant additional burdens. Originality/value Despite growing attention to conscious leadership and purpose, empirical research on how leaders shape culture in SMEs remains scarce – particularly in emerging economies such as Mexico, where strong founder imprinting and weaker formal institutionalization make leadership influence especially salient and observable. By theorizing and empirically testing higher purpose as a sensegiving mechanism, this study moves conscious capitalism toward greater explanatory rigor, offering a dual-pathway framework for cultivating ethical cultures through leadership enactment and purposeful institutionalization.

    Integrity in Motion: Regrounding UDHR’s Article 18 through Malik’s ‘Freedom of Becoming’
    (Oxford University Press (OUP), 2026-04-10)
    Pallares-Yabur, Pedro  
    Article 18’s limits remain doctrinally unsettled. Drawing on unpublished lectures and notebooks by Charles H. Malik (1939–46), this article reconstructs the philosophical genealogy of the UDHR’s ‘right to change’ and contrasts it with standard diplomatic narratives. The archival record reveals Malik’s depth of grammar of the person as ens in via, with dignity understood as a vertical ascent towards truth. Malik’s anthropology, I argue, supplies a powerful justificatory grammar for the UDHR’s ‘right to change’, a grammar that can illuminate the final text without denying the pluralist dynamics of the drafting process. Translating this ‘freedom of becoming’ into adjudication, I propose a double yardstick for limitations: integrity cost, namely, whether a rule forces misalignment between conviction and conduct, and concrete third-party harm, specific and nonspeculative harms to which restrictions must be narrowly tailored. This reframing casts neutrality as relational reasonableness and equips courts to protect conscience without theological line drawing, regrounding Article 18’s normative core across jurisdictions.

    Sports organizations’ duty to protect athletes’ dignity: a universal human rights analysis to comply with the prohibition of non-accidental violence in sports regulations
    (Springer Science and Business Media LLC, 2025-07-19)

    Modern sports organizations, like the Fédération Internationale de Gymnastique and the Fédération Internationale de la Football Association, prohibit different forms of non-accidental violence, including sexual harassment, sexual abuse, physical abuse, psychological abuse, and neglect. This prohibition relates to a sports organization’s modern duty to protect human rights and dignity during all activities. In practice, however, it is often difficult to determine when a sports organization member’s acts or conduct crosses the line of intrinsic sporting demands to become harassment, physical or psychological abuse, or neglect towards another member. Sports law literature is scarce on this issue. The authors provide a contemporaneous answer to this question revisiting the meaning of human dignity and its relation to the right of freedom from degrading treatment. The authors offer a test to answer the question ¿when an act or conduct reaches the standard of non-accidental violence in the professional sports context? They also apply their proposed test to real-life scenarios of potential non-accidental violence in sports.

    Wireless Sensor Networks are increasingly deployed in mission-critical scenarios where resilience and energy efficiency are paramount. This paper presents a hybrid architecture combining Bluetooth Low Energy (BLE) and Long Range (LoRa) technologies to enhance both robustness and energy-aware performance in adversarial environments characterized by reactive jamming attacks. A comprehensive experimental testbed was developed, integrating BLE and LoRa nodes, a dual-protocol gateway, and a reactive jammer emulator. We introduce an adaptive clustering algorithm that performs energy-aware role assignment and jamming mitigation based on signal anomaly detection and multi-metric routing. To validate its effectiveness, we conducted an extensive time-series analysis on energy consumption, retransmission rates, and signal resilience under both mitigated and non-mitigated conditions across BLE-only, LoRa-only, and hybrid BLE-LoRa networks. The results show protocol-dependent performance trade-offs under the proposed mitigation algorithm. While LoRa-only and hybrid BLE–LoRa networks exhibit consistent reductions in energy consumption, retransmissions, and variability, the BLE-only configuration demonstrates improved resilience at the cost of a moderate increase in energy usage and retransmission activity due to clustering and control overhead. Notably, the BLE-LoRa architecture balances delivery assurance and energy efficiency while maintaining communication even under interference. Furthermore, we provide statistical modeling and hypothesis testing confirming the mitigation algorithm’s significant impact. These findings offer a critical empirical contribution to the design of resilient and energy-aware heterogeneous WSNs and demonstrate the viability of real-time adaptive mitigation strategies for emerging smart environments.

    Modeling, Modulation and Control of Hexverter-Based Modular Multilevel Converters
    (University of Colorado Denver, 2022)
    Robles-Campos, Héctor R.  
    Electrical power extraction from renewable energy sources such as photovoltaics (PV), wind farms, and some others, have their own technical challenges. It is necessary to perform the power processing tasks according to the nature of the power supply and, at the same time, it is required to be compliant with technical regulations and particular needs of final users. These tasks are achieved with the development of power electronics converters and suitable control systems. Modular multilevel converters (MMCs) have been during the last years, and will continue to be in the near future, a trending research topic. To better process the electrical power, MMCs can be used where two or three level power converters are used today. This is essentially due to multiple advantages, such as, (i) inherent fault tolerance or some times called redundancy, (ii) application in medium and high power levels, (iii) high scalability: in function of the number of power modules, (iv) better quality of output power, and (v) comparatively low switching frequency.

    Wireless communication networks based on IEEE 802.15.4 and ZigBee PRO constitute a critical component of smart grid infrastructures, where reliability and availability requirements exceed those typically assumed in low-power wireless deployments. Despite extensive analytical modeling, most existing studies rely on independence assumptions for packet errors and simplified abstractions of reassociation dynamics. This work presents stochastic reliability characterization grounded on real MAC-layer traffic capture from an operational IEEE 802.15.4/ZigBee PRO network. The methodology combines statistical hypothesis testing, first-order Markov modeling, spectral-gap analysis, large-deviation theory, renewal processes, and survival analysis of realignment intervals. Empirical results reject the hypothesis of independent frame errors and demonstrate significant temporal dependence with geometric mixing behavior. The estimated transition structure reveals burst-error persistence, inflating long-run variance relative to memoryless models. Furthermore, coordinator realignment intervals deviate from exponential behavior, exhibiting non-constant event rates consistent with regenerative dynamics. These findings indicate that effective communication reliability is governed not only by average frame error probability but also by dependence structure and regeneration mechanisms. The proposed probabilistic framework provides a rigorous and reproducible methodology for dependence-aware reliability assessment in smart grid communication systems.
