Stigma in Access to HIV Treatment in African Settings: The importance of social connections

open access: yesGrounded Theory Review: An International Journal, 2011
Access to antiretroviral therapy is desperately needed in Nigeria. Increased access to anti-retroviral therapy for HIV treatment contributes to improved quality of life and reduced health care costs.

A Framework for Messy Communication: A Qualitative Study of Competing Voices of Authority on Social Media

open access: yesAdministrative Sciences
While governments, nonprofits, and influencers differ dramatically in their resource availability for social media content creation and their duties to public safety, health, and welfare, all play a role in communication with the public at large ...

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

open access: yesAdvanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Discovery as Basic Methodology of Qualitative and Quantitative Research

open access: yesForum: Qualitative Social Research, 2001
The paper argues 1. that methodologies of qualitative research in psychology and the social sciences should be directed toward discoveries rather than reflexive interpretations. It gives a critical account of hermeneutics and the "interpretative paradigm"

Variable Stiffness Flexure Structures Enabled by Phase‐Change Gallium and Adhesive Interfacial Locking for Soft Robotic Applications

open access: yesAdvanced Engineering Materials, EarlyView.
A flexure‐based variable stiffness structure is developed by integrating phase‐change modulation and adhesive interfacial locking of gallium. The design enables a wide stiffness variability, transitioning from soft, flexible behavior to rigid, load‐supporting performance.

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

open access: yesAdvanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Air‐Pressure–Actuated Vibroacoustic Metamaterial With Tunable Bandgap: Design, Modeling, and Characterization

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents the design, modeling, and characterization of air‐pressure–actuated programmable vibroacoustic metamaterials (PVAMM). The study focuses on leveraging air pressure to dynamically tune resonance frequencies for effective noise attenuation.

Rafting of Ni‐Based Superalloys Under Multiaxial Load as Understood by Phase‐Field Simulations and Critical Experiments

open access: yesAdvanced Engineering Materials, EarlyView.
Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

open access: yesAdvanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Relevancia de la Psicobiografía en el estudio psicológico

open access: yesClínica Contemporánea
La psicobiografía, pese a contar con un largo recorrido de aplicación en otros países, apenas es conocida en España y mucho menos es empleada en la investigación y formación en psicología. El presente artículo explica y delimita conceptualmente el método
