Intellectual competence and academic performance: A Spanish study

This study assessed the explanatory power of the intellectual competence (IC) model for understanding the relationship among the main ability and non-ability determinants of academic performance (AP) in a sample of Spanish undergraduates. Thus it attempted to replicate the preliminary evidence for this model provided in a recent UK study and expand on it by including more comprehensive measures of intelligence and AP. Results showed mixed support for individual paths, but good support for the overall model. The expanded IC model showed that some individual difference factors explain AP variance that is common to high school, university entry, and university exam grades, whereas other individual differences explained AP variance specific to university. Inconsistencies, limitations, and implications are discussed.     

Conceptualizing impact in academic development: finding a way through

This paper explores the notion of impact in the context of academic development programs and considers how it can be described and understood. We argue that impact has a range of meanings and academic development programs such as graduate certificates have a broad group of stakeholders and hence the impact is different for each group depending on how the program aims and objectives are defined and understood. In finding a way through the difficulties of evaluating impact in academic development we point to the importance of clearly conceptualizing the notion of impact, a careful identification of the assumptions underpinning any program and an understanding of who academic development will benefit and how. We suggest that impact in academic development cannot be understood without taking account of the range of possible impacts and the difficulty of attributing simple cause and effect to a complex environment.     

Deterioration of building materials and artworks in the ‘Santa Maria della Stella’ church,Saluzzo (Italy): Causes of decay and possible remedies

An in-depth scientific survey revealed the deterioration mechanisms affecting the ‘Santa Maria della Stella’ church in Saluzzo, Italy, where various salt crystallization processes are strongly damaging the building materials and artworks. Rainwater seepage permeates the vault and interior, causing: (1) epsomite growth as interstitial columnar crystals (resulting in pictorial coating detachment) or superficial, powdery efflorescence; (2) formation of nesquehonite/hydromagnesite crusts on wall paintings; and (3) nitratine growth causing pigment staining and detachment. These processes involve selective Mg²⁺ mobilization from magnesian-lime mortars and bacterial-induced formation of nitrates from guano, with consequent precipitation of degrading salts. The study confirms how characterization of all deterioration agents is fundamental to planning a viable cultural heritage conservation and restoration programme.     

Navigating the Path to College: Latino Students’ Social Networks and Access to College

Based on a qualitative study in Indiana, this article examines the college preparation process of Latino high school students. It uses social capital theory to identify the ways families, peers, and school staff members contribute to students’ access to college across the stages of college preparation. Findings suggest that students receive strong support in their development of aspirations from families, but they face multiple challenges in accessing the information and support they need to realize their college goals. It offers implications for families, schools, and higher education institutions on how to more effectively support college access for Latino students.     

When does a nation-level analysis make sense? ESD and educational governance in Brazil,South Africa,and the USA

International policy analysis tends to simplify the nation state, portraying countries as coherent units that can be described by one statistic or placed into one category. As scholars from Brazil, South Africa, and the USA, we find the nation-centric research perspective particularly challenging. In each of our home countries, the effective influence of the national government on education is quite limited, particularly in fringe and emerging areas of education such as Education for Sustainable Development (ESD) and Climate Change Education (CCE). This essay explores how nation-level comparisons are and are not useful for international research on ESD and CCE. We consider several layers of decentralized governance, but ultimately come to the conclusion that ESD governance in our respective countries is polycentric rather than decentralized. We discuss the implications of this idea for cross-national policy research on ESD and CCE.     

The Relationship Between Counseling Self-Efficacy and Communication Skills of Volunteer Rape Crisis Advocates

This research examines the relationships between communication competence, communication anxiety, and five subdimensions of counseling self-efficacy. The sample consists of volunteers trained at two rape crisis centers (n = 63) over a one-year period. As hypothesized, communication anxiety was negatively related and communication competence positively related to the subdimensions of counseling self-efficacy. Results suggest that training programs need to be aware of how personality characteristics may affect a volunteer's ability to become an efficacious counselor. Implications for how rape crisis centers can integrate these communication issues into their training programs and improve the self-efficacy of their advocates are discussed.     

Teacher Conceptions and Approaches Associated with an Immersive Instructional Implementation of Computer-Based Models and Assessment in a Secondary Chemistry Classroom

This paper reports on a case study of an immersive and integrated multi-instructional approach (namely computer-based model introduction and connection with content; facilitation of individual student exploration guided by exploratory worksheet; use of associated differentiated labs and use of model-based assessments) in the implementation of coupled computer-based models and assessment in a high-school chemistry classroom. Data collection included in-depth teacher interviews, classroom observations, student interviews and researcher notes. Teacher conceptions highlighted the role of models as tools; the benefits of abstract portrayal via visualizations; appropriate enactment of model implementation; concerns with student learning and issues with time. The case study revealed numerous challenges reconciling macro, submicro and symbolic phenomena with the NetLogo model. Nonetheless, the effort exhibited by the teacher provided a platform to support the evolution of practice over time. Students' reactions reflected a continuum of confusion and benefits which were directly related to their background knowledge and experiences with instructional modes. The findings have implications for the role of teacher knowledge of models, the modeling process and pedagogical content knowledge; the continuum of student knowledge as novice users and the role of visual literacy in model decoding, comprehension and translation.     

Ni de Aquí, Ni de Allá: Conceptualizing the self-authorship experience of gay Latino college men using conocimiento

This essay aims to enhance our conceptual understanding of students with intersectional identities, specifically gay Latino men in college. We first explain how ethnic, gender, and sexual identities can act as compounding influences. Second, we review two distinct but complementary developmental theories. Conocimiento captures the disruptive, challenging path experienced by marginalized Latino youth. Self-authorship situates the broader developmental process in and beyond college. Our modified framework—conociéndose y escribiéndose—conceptualizes how college students navigate multiple marginalized identities. Finally, we discuss the implications of this intersectional framework for LGBTQ+ students and institutions seeking to enhance diversity, inclusion, and student success.     

Science Letters：Visual odometry for road vehicles —— feasibility analysis

Estimating the global position of a road vehicle without using GPS is a challenge that many scientists look forward to solving in the near future. Normally, inertial and odometry sensors are used to complement GPS measures in an attempt to provide a means for maintaining vehicle odometry during GPS outage. Nonetheless, recent experiments have demonstrated that computer vision can also be used as a valuable source to provide what can be denoted as visual odometry. For this purpose, vehicle motion can be estimated using a non-linear, photogrametric approach based on RAndom SAmple Consensus (RANSAC). The results prove that the detection and selection of relevant feature points is a crucial factor in the global performance of the visual odometry algorithm. The key issues for further improvement are discussed in this letter.
