Sextortion or Cybersextortion; delimitation of the term

In Law, and in Criminal Law in particular, terms, designations, and concepts must be so specific that they alone are capable of avoiding ambiguous interpretations. Therefore, this article aims to reflect on the use of the term Cybersextortion instead of Sextortion in order to clarify the use of each in identifying the phenomenon being analyzed.; Em Direito, e em Direito Penal em particular, os termos, designaçõ...

Deltopectoral or Anterosuperior Approachin Total Reverse Shoulder Arthroplasty:...

Introduction: Our purpose was to evaluate the differences in metaglene positioning in deltopectoral and anterosuperior approach in total reverse shoulder arthroplasty. Methods: Patients who underwent total reverse shoulder arthroplasty for degenerative or traumatic pathology within a 10‐year period were selected. Two groups were created: group 1, deltopectoral approach; group 2, anterosuperior approach. The met...

Team Psychological Capital: Comparative psychometric study of two versions of t...

The globalized and competitive world underscores the relevance of positive organizational behavior, specifically team psychological capital (PsyCap). Indeed, teams are crucial to organizational success, and the study of PsyCap at the team level makes a significant contribution to both research and practice. Assessing the levels of PsyCap and/or its dimensions (self-efficacy, resilience, hope, and optimism) to u...

Grating coupler design for low-cost fabrication in amorphous silicon photonic i...

Photonic circuits find applications in biomedicine, manufacturing, quantum computing and communications. Photonic waveguides are crucial components, typically having cross-section orders of magnitude inferior when compared with other photonic components (e.g., optical fibers, light sources and photodetectors). Several light-coupling methods exist, consisting of either on-plane (e.g., adiabatic and end-fire coup...

Qual a influência da virtualidade na satisfação dos membros com a equipa? O pap...

Objetivos/Enquadramento teórico O presente estudo pretende analisar a influência da virtualidade na satisfação dos membros com a equipa, quer direta, quer indireta, por via do seu impacto na perceção de subgrupos. Paralelamente, procura-se contribuir para clarificar a natureza destas relações através da análise do papel moderador da confiança afetiva. A virtualidade está cada vez mais presente nas organizações,...

Green Human Resource Management: A Bibliometric Analysis

Multichannel detector system for surface plasmon resonance biosensors

Photonic systems are gaining an important role in the field of medical diagnosis due to the achievable high sensitivity and selectivity and low cost, enabling the fabrication of disposable point of care diagnosis systems for multiple pathologies. In this work we present the detector subsystem developed for a multi-channel surface plasmon resonance (SPR) based sensor. The core of the system is a multimode interf...

Cross-section mismatch: metamaterials to the rescue

Coupling light into and/or out of a photonic integrated circuit is often accomplished by establishing a vertical link between a single-mode optical fiber and a resonant waveguide grating, which is then followed by a tapered and a single-mode waveguides. The tapered waveguide operates as a spot-size converter, laterally expanding or contracting the light beam between the single-mode waveguide and the resonant wa...

Colour and image processing for output extraction of a LSPR sensor

Sensors based on the Local Surface plasmon Resonance (LSPR) are attractive due to their simple structure and good sensitivity, but the expensive optoelectronic part of the device is limiting the practical applications. There is a need for new strategies to bring the excellent detection properties of LSPR sensors to the playground of low-cost devices and materials. In this work, it is proposed a novel approach t...
