Trang: This study examines how university career guidance activities are associated with students’
career self-direction, with career decision-making self-efficacy (CDMSE) serving as a mediating
mechanism. An exploratory sequential mixed-methods design was conducted at Ho Chi Minh City
University of Economics and Finance (UEF), a private university in Vietnam. The qualitative phase
involved 15 interviews to refine the activity groupings and measurement instruments and to support
interpretation of the quantitative findings. The quantitative phase incoporate PLS-SEM using 525
valid responses from third- and fourth-year students. CDMSE was in positive association with
career self-direction (β = .579, p < .001). Of the eight career guidance activity groups, only
workshops/seminars and career clubs indicated significant positive associations with CDMSE and
significant indirect associations with career self-direction through CDMSE. Career information
repositories, coaching/mentoring, field trips, career fairs, internships/practicums, and
hackathons/professional competitions were not statistically significant. The findings suggest that
universities should prioritize the developmental quality of career guidance by incorporating
structured reflection, repeated engagement, and continuous feedback into program design and
implementation.

Trang: The research examines the impact of macroeconomic conditions on country-level freight rates in leading automotive component export countries. Secondary data of 240 monthly observations were collected for global macroeconomic variables and ocean freight rate proxies in the US, Japan, South Korea, and Germany. Using Vector autoregression, combined with Granger-causality, impulse response functions and forecast error variance decomposition, the study found varying significant effects from macroeconomic conditions. The study used counterfactual analysis to identify an indirect transmission channel whereby global freight rates dampens macroeconomic effects in South Korea and Japan, while strengthening those in Germany. From these results, recommendations are made for automotive component exporters to adapt to each country’s unique sensitivity to manage increasingly volatile maritime freight costs.

Trang: This study examines the impact of green logistics experience on consumers’ intention to
participate in circular practices within Vietnam’s eco-beauty market. Based on the Stimulus-
Organism-Response framework, the study tests the effects of green delivery service quality,
sustainable fulfillment packaging experience, reverse logistics service support, and circular
logistics information transparency, with perceived convenience and perceived circular value as
mediators. Data from 529 eco-beauty consumers in Vietnam were analyzed using PLS-SEM.
The results indicate that green delivery service quality, sustainable fulfillment packaging
experience, and reverse logistics service support significantly enhance perceived convenience,
which in turn strengthens the intention to participate in circular practices. Perceived convenience
also serves as a mediator in these relationships. However, the value-based pathway is less
consistent. Reverse logistics service support does not significantly affect perceived circular
value, while the effects related to circular logistics information transparency and perceived
circular value run opposite to the expected direction. The findings suggest that circular
participation in eco-beauty depends more on reducing consumer effort than on value-based
messages alone.

Trang: The two types of classification error in credit scoring carry very different costs: a false negative
is far more expensive than a false positive. Using 57,187 loan-level records from a Vietnamese
commercial bank, of which 1.23% are non-performing, we evaluate six machine learning models
and four voting ensembles. Because missing a non-performing case is the costlier error, we
prioritise recall and the F2 score in model selection. We also separate application-time predictors
from post-origination information, evaluating each model against only the data available at its
decision stage. The behavioural model reaches an AUC of 0.992, reflecting concurrent
discrimination driven by accumulated loan tenure rather than early warning. Restricted to
origination information, discrimination falls to 0.82-0.87, yet the model still ranks risk usefully,
with the riskiest fifth of applicants containing about 72% of non-performing cases. Repayment-
related variables provide the most predictive information, and recall-oriented ensembles catch most
non-performing borrowers, with recall between 0.91 and 0.93. The practical message is that model
evaluation should be tied to the information available at each decision point and to the relative cost
of the errors that matter most.
