I hope this message finds you well. I recently read the article "Designing a Positive Health Dialogue Tool for Adolescents and Young Adults: A Mixed Methods Study" published by your journal. First, I commend the authors, Marja van Vliet, Machteld Huber, and Sigrid van der Zanden, for their efforts and valuable insights in this research. The authors have designed a dialogue tool to assist young individuals aged 16–25 in navigating various health and vulnerability-related issues, applicable across multiple domains, such as healthcare and social interactions [1]. However, I believe that the article may have certain limitations that warrant attention, and I would like to offer some suggestions for improving future research. First, the sample size used in the study is relatively small (N = 118), particularly for the qualitative component (N = 36). This limited sample size may compromise the reliability and generalisability of the findings. Second, there is a notable gender imbalance within the sample, with 79% of participants being female, and the study focuses mainly on individuals in the Netherlands, which may limit the diversity of perspectives. Third, the study does not assess the long-term effects of the dialogue tool, particularly concerning its sustained influence on health perception and resilience. Fourth, the data is primarily based on self-reports from participants, which may introduce subjective biases [2]. Fifth, the discussion on the study's limitations is insufficient, lacking an in-depth examination of how these limitations might impact the generalisability and applicability of the findings. For example, issues such as sample representativeness, the tool's applicability across diverse contexts, and the limitations inherent in qualitative data were not adequately addressed. To enhance the quality of this study, several suggestions for improvement could be considered: First, the small sample size may affect the reliability and generalisability of the findings [3]. I recommend that future studies either increase the sample size or provide justification for sample size adequacy based on expected precision estimates [4, 5]. Second, to improve the external validity of the findings, I suggest conducting research with a more diverse sample that incorporates participants from different cultural contexts and includes a balanced gender ratio. Third, future studies could employ a longitudinal design to track participants over time, which would allow for the assessment of the sustained effects of the tool on health perception and resilience, thereby providing stronger empirical support and enhancing the long-term applicability of the conclusions. Fourth, future research should incorporate objective data sources (e.g., medical records) to mitigate the influence of subjective biases. Fifth, I recommend a more comprehensive analysis in the conclusion regarding sample representativeness, the applicability of the tool in diverse contexts, and the limitations of qualitative data. This would help readers better understand the scope and limitations of the study's findings. Cheyuan Liu: conceptualization, writing–review and editing.

Applications of the directional solidification in magnetic shape memory alloys

IOP Conference Series Materials Science and Engineering (2016)

Yitong Huang J Liu Qiaodan Hu qingsheng liu İbrahim Karaman

A zone melting liquid metal cooling (ZMLMC) method of directional solidification was applied to prepare highly-oriented Ni52Fe17Ga27Co4 magnetic shape memory alloys. At high temperature gradient and low growth velocity, the well-developed preferred orientation for coarse columnar crystals was obtained. Such a structure leads to a large complete pseudoelastic recovery of 5% at 348 K. Moreover, the pseudoelastic behaviours and the kinetics of the martensitic transformation (MT) are significantly affected by the intersection angle between the loading direction and the grain boundaries.
