Background: Interest is growing surrounding functional foods, which provide health benefits in addition to nutritional value. In particular, there is a focus on pulse crops which contain high levels of polyphenolics, such as lentils. Methods: In this study, polyphenols were extracted from five L. culinaris varieties and characterized by both their antioxidant profile and cytotoxic activity. Result: Hulled varieties had a high content of secondary metabolites (>70 mg GAE/g), while all varieties demonstrated high antioxidant potential (1570-2020 Oxygen Radical Absorbance Capacity index). Furthermore, all extracts showed significant cytotoxicity against H9C2, HepG2, A549 and Calu-1 cancer cell lines. This recommends further investigation into the specific compounds present in L. culinaris, which could potentially be exploited for their anti-cancer activity.

With current policy concerns about shortfalls of labour supply and effects on the social welfare system due to population ageing, there is a need to understand the factors that shape women's choices about if, when and how to retire. Recent trends indicating the increased workforce participation of women demand new policy responses to the end of careers and retirement transitions to sustain acceptable levels of participation and productivity. This book is innovative in that it will examine constellations of factors that disadvantage or advantage women's career and retirement trajectories against a backdrop of public policy efforts to extend working lives.

Confirmatory factor analysis and exploratory structural equation modeling of the structure of attention-deficit/hyperactivity disorder symptoms in adults

The Depression Anxiety and Stress Scales-21 (DASS-21) involves a simple structure firstorder three-factor oblique model, with factors for depression, anxiety, and stress. Recently, concerns have been raised over the value of using confirmatory factor analysis (CFA) for studying the factor structure of scales in general. However, such concerns can be circumvented using exploratory structural equation modeling (ESEM). Consequently, the present study used CFA and ESEM with target rotation to examine the factor structure of the DASS21 among an adult community. It compared first-order CFA, ESEM with target rotation, bifactor CFA (BCFA), and bi-factor BESEM with target rotation model with group/specific factors for depression, anxiety, and stress. A total of 738 adults (males = 374, and females =364; M = 25.29 years; SD = 7.61 years) completed the DASS-21. While all models examined showed good global fit values, one or more of the group/specific factors in the BCFA, ESEM with target rotation and BESEM with target rotation models were poorly defined. As the firstorder CFA model was most parsimonious, with well-defined factors that were also supported in terms of their reliabilities and validities, this model was selected as the preferred DASS21 model. The implications of the findings for use and revision of the DASS-21 are discussed

Description:
Aspiring and established strength and conditioning professionals are increasingly seeking opportunities to further their knowledge to gain a competitive advantage within the highly competitive profession. Postgraduate degree programs in the discipline are therefore becoming a popular option for academic institutions to meet the demands of the workforce and marketplace. The purpose of this article is to bring together experienced practitioners and applied academics to offer considerations for the prospective strength and conditioning postgraduate student. Furthermore, this piece can be considered by academics that are responsible for the development of such programs. Future students are encouraged to reflect on their strengths and weaknesses, current and intended career trajectory, and work-life circumstances. Students' needs and wants, industry demands, and teaching and learning processes must be well understood by academics responsible for developing these programs. Finally, factors such as coursework and research content, authentic teaching and learning tasks, professional practice, and accreditation requirements represent key considerations of a successful postgraduate strength and conditioning program.
