Global agricultural value chains and food prices

American Journal of Agricultural Economics, EarlyView.
Abstract We study the relationship between the extent of participation in global agricultural value chains (GAVCs) and food prices at the country level. Using longitudinal data on a sample of 138 countries for the period 2000–2015 and a shift‐share instrumental variable design, we study how the extent of a country's participation in GAVCs in a given ...

Single Phase Variable Reluctance Motor Design Using Particle Swarm Optimization

Latin-American Journal of Computing
Electrical engines are built under electromagnetism concepts to create mechanical power, those can be seen as simple machines, as it depends on reluctance, even being called as “reluctance motor”, what gives this engine the possibility of being widely ...

Parameter optimization and characteristic analysis of tangentially magnetized reverse-salient permanent magnet synchronous motor

Discover Applied Sciences
Reverse-salient permanent magnet synchronous motors have reverse-salient characteristics, and the direct-axis inductance is larger than the quadrature-axis inductance. Compared with the traditional positive-salient permanent magnet synchronous motor, the

When Urgency Drops: Temporal Consciousness and the Choreography of Dying

Anthropology of Consciousness, EarlyView.
ABSTRACT In the hospital, the transition from fighting for life to preparing for death involves not only a shift in medical repertoires but also a profound transformation in temporal experience. Drawing on ethnographic fieldwork in a Canadian intensive care unit, this article examines how the tempo of care, its rhythms, urgencies, and pauses shapes ...

From Developmental State to Platform State: The Case of South Korea's AI Policy

Asia Pacific Viewpoint, EarlyView.
ABSTRACT This research note examines South Korea's artificial intelligence (AI) strategy to illustrate the emergence of state platformization—a governance mode where the state acts as a provider of digital infrastructures, data, and standards. Moving beyond traditional developmental models, this study conceptualizes the state as a platform operator ...

Review: Internet‐based cognitive behavioral therapy for children and adolescents with anxiety disorders – a meta‐analysis of efficacy and impact of age and support

Child and Adolescent Mental Health, EarlyView.
Background Anxiety disorders are highly prevalent in childhood and adolescence, but access to treatment is limited. Internet‐based cognitive behavioral therapy (ICBT) has been proposed as an effective treatment to increase accessibility to evidence‐based treatment.

Promotion of Emotional Competencies in Auxiliary Grandparents Caregivers: A Pilot Prevention Programme

Child &Family Social Work, EarlyView.
ABSTRACT This study examined the efficacy of a 5‐week combined psychoeducation and support programme aimed at enhancing emotional competencies and psychological well‐being among Spanish auxiliary grandparent caregivers. Two delivery formats (face‐to‐face and synchronous online) were compared with a control group receiving no intervention, and ...

SlideSAVR: Enabling Live Analysis during Data Presentations via Multimodal Sketching and Voice Input

Computer Graphics Forum, EarlyView.
Abstract Interpersonal communication in data science can yield sought‐after insights, but presentation environments are often not conducive for live analysis, forcing the process to move offline. Through a formative survey with 16 participants, we identified both technical (e.g., complexity of tools) and psychological (e.g., pressure of programming ...
