It's bigger on the inside: mapping the black box of motivation.
Behav Brain Sci
January 2025
Department of Life Sciences, University of Trieste, Trieste,
Many motivational constructs are opaque "black boxes," and should be replaced by an explicit account of the underlying psychological mechanisms. The theory of motivational systems has begun to provide such an account. I recently contributed to this tradition with a general architecture of motivation, which connects "energization" and "direction" through the goal-setting activity of emotions, and serves as an evolutionary grounded map of motivational processes.

JPRAS Open
March 2025
Plastic & Reconstructive Surgery Department, Prince Sultan Military Medical City, Riyadh, Saudi Arabia.
Background: Metacarpal shaft fractures account for 30 % of all hand fractures, and long oblique and spiral shaft fractures represent a significant quantity. Closed or open reduction and internal fixation is generally indicated for unstable fractures, rotational malalignment or significant metacarpal shortening. Various techniques can achieve appropriate fixation, though no single technique has been proven to be superior across all cases.

Front Surg
January 2025
Research Institute of Orthopedics, The Affiliated Jiangnan Hospital of Zhejiang Chinese Medical University, Hangzhou, China.
Purpose: In this study, we aimed to assess the occurrence of hidden blood loss (HBL) and its associated risk factors in patients with lumbar degenerative diseases who underwent percutaneous endoscopic transforaminal lumbar interbody fusion (Endo-TLIF).
Methods: Sex, age, height, weight, body mass index, and medical history including hypertension, diabetes, and osteoporosis were recorded. The duration of symptoms, preoperative lumbar subcutaneous fat tissue thickness (measured using midsagittal T2-weighted magnetic resonance imaging), lumbar disc degeneration grade, and other basic patient information were also documented.
Diagnostic performance of optical spectral transmission compared to magnetic resonance imaging in patients with inflammatory arthritis.
Arthritis Res Ther
January 2025
Rheumazentrum Ruhrgebiet Herne, Ruhr University Bochum, Herne, Germany.
Background: Optical spectral transmission (OST) is a modern diagnostic method capable of quantifying inflammation in the finger and wrist joints of arthritis patients by assessing the blood-specific absorption of light transmitted through a tissue. The diagnostic performance of this modality has not been adequately examined and data regarding OST associations with magnetic resonance imaging (MRI) are limited. Aim of this study was therefore to investigate the performance of OST in assessing joint inflammation as compared to MRI in patients with inflammatory arthritis (IA).

BMC Public Health
January 2025
Faculty of Physical Education and Health, Lin yi University, Lin yi, 276006, China.
Objective: Based on the self-determination theory, the three types of autonomy support of parents, teachers and peers as a whole were included in the same research system to explore their effects on exercise adherence of higher vocational college students and their internal mechanisms.
Methods: The study used the exercise autonomy support scale, autonomous motivation scale and exercise adherence scale to construct and test the hypothesised pathways for promoting exercise adherence among students in higher vocational college. Using the data obtained from a survey of 436 higher vocational college students as the unit of analysis, and taking into account the variable of students' self-determined motivation.
