Computer-aided diagnosis has been slow to develop in the field of oral ulcers. One of the major reasons for this is the lack of publicly available datasets. However, oral ulcers have cancerous lesions and their mortality rate is high. The ability to recognize oral ulcers at an early stage in a timely and effective manner is a very critical issue. In recent years, although there exists a small group of researchers working on these, the datasets are private. Therefore to address this challenge, in this paper a multi-tasking oral ulcer dataset (Autooral) containing two major tasks of lesion segmentation and classification is proposed and made publicly available. To the best of our knowledge, we are the first team to make publicly available an oral ulcer dataset with multi-tasking. In addition, we propose a novel modeling framework, HF-UNet, for segmenting oral ulcer lesion regions. Specifically, the proposed high-order focus interaction module (HFblock) performs acquisition of global properties and focus for acquisition of local properties through high-order attention. The proposed lesion localization module (LL-M) employs a novel hybrid sobel filter, which improves the recognition of ulcer edges. Experimental results on the proposed Autooral dataset show that our proposed HF-UNet segmentation of oral ulcers achieves a DSC value of about 0.80 and the inference memory occupies only 2029 MB. The proposed method guarantees a low running load while maintaining a high-performance segmentation capability. The proposed Autooral dataset and code are available from https://github.com/wurenkai/HF-UNet-and-Autooral-dataset. [ABSTRACT FROM AUTHOR]

Objective: To determine what firearm policies New Jersey residents believe will prevent school shootings and the extent to which this varies by sex, firearm ownership status, and political affiliation. Methods: A representative sample of New Jersey residents (N = 1,018) was collected via the Eagleton Center on Public Interest Polling (ECPIP). Data were weighted to reflect the state's population. Participants were asked to rate how helpful they perceived different firearm-related policies to be for preventing school shootings. Results: Findings indicate that participants perceived universal and expanded background checks, increased mental health funding, and requiring a license for firearm purchases as most effective for preventing school shootings. Arming school personnel, prayer in schools, decreasing the number of entrances at schools, and secure storage requirements were viewed as less effective. Firearm ownership, sex, and political affiliation significantly influenced perceptions of the effectiveness of these policies. Conclusion: The study examined the perceived effectiveness of policies to prevent school shootings. The study highlights disparities and commonalities in policy support among different groups, emphasizing the importance of collective efforts to address gun violence in schools.

Background: The retail market for toddler-specific packaged foods is growing. Many of these products are ultra-processed and high in nutrients of concern for health, yet marketed in ways that may make them appear wholesome. This study aims to assess parents' responses to claims on unhealthy, ultra-processed toddler food products and test whether removing such claims promotes more accurate product perceptions and healthier product preferences. Methods: Parents of toddlers aged 12 to < 36 months (N = 838) were recruited for an online experiment testing four on-pack claim conditions: control (no claim); 'contains "good" ingredient'; 'free from "bad" ingredient'; and unregulated 'child-related' claim. Participants were randomly assigned to one condition, then viewed images of toddler food products that varied in nutrition content and the claims displayed. Participants completed tasks assessing product preferences (unhealthy product displaying claim vs. a healthier option with no claim, across four food categories (banana bars, strawberry snacks, blueberry yogurt snacks and veggie snacks)), purchase intentions and product perceptions. Poisson regression (count variable) and linear regression (continuous outcomes) analyses were employed to test for mean differences by marketing claim conditions. Results: For the overall sample, brief exposure to 'free from "bad" ingredient' claims increased participant's intentions to purchase unhealthy food products for their toddlers, but there was no clear evidence that 'contains "good" ingredient' claims and 'child-related' claims significantly impacted parent's preferences, purchase intentions and perceptions of toddler foods. However, certain claims influenced particular parent subgroups. Notably, parents with three or more children chose more unhealthy products when these products displayed 'contains "good" ingredient' or 'free from "bad" ingredient' claims; the latter claims also promoted stronger purchase intentions and enhanced product perceptions among this subgroup. Conclusions: Findings indicate that 'free from "bad" ingredient' claims on unhealthy toddler foods are of most concern, as they boost the appeal of these products to parents. 'Contains "good" ingredient' claims and 'child-related' claims showed limited effects in this study. Considering available evidence, we recommend claims should not be permitted on child-oriented foods, as they may promote inaccurate product perceptions and unhealthy product choices by parents, that can detract from their children's diets and health.

The article, titled "A Good-bye Note," is a farewell message from the outgoing editor-in-chief of the journal Theory & Practice of Second Language Acquisition. The editor expresses gratitude to the co-editor-in-chief, the editorial team, referees, and contributors for their support in establishing and maintaining the journal's reputation since its inception in 2015. The editor also acknowledges the hard work of the publisher, University of Silesia Press, and its dedicated team. The editor hopes that the journal will continue to thrive as a platform for the exchange of ideas in the field of second language acquisition. [Extracted from the article]

Introduction: Service users are increasingly participating in health research. Although collaborative research is assumed to give users a sense of psychological ownership, little is known about the specific psychosocial processes through which ownership develops and is displayed. The present study yields insight into a process in which service users, researchers and a website designer collaborated to design a website. Aim: The aim of this study was to explore how participants developed and displayed feelings of ownership during a collaborative process to design a website. Methods: A case study design was adopted by which audio recordings were subjected to thematic analysis and interpreted by drawing on the concept of psychological ownership. Findings: A sense of psychological ownership of the website design process emerged in two distinct and overlapping phases. In the first phase, 'sense of ownership during the early design phase', only researchers and the website designer displayed a sense of ownership, which was facilitated by the research context preceding the collaborative workshops. In the second phase, 'sense of ownership during the collaborative design phase', service users gradually started to develop parallel feelings of ownership that were facilitated by workshop design activities. These activities enabled service users to increasingly control the process, to invest themselves in the process and to gain intimate knowledge of the process and its outcome. Service users' sense of ownership was displayed in their statements about the website and its elements. Conclusion: Participants engaged in codesign processes may develop a sense of psychological ownership at different speeds because of contextual factors. It is important to take this into account as it may complicate the formation of egalitarian work groups. Patient and Public Contribution: Parents of children with suicidal behaviour and a counsellor participated as service users in a website design process. [ABSTRACT FROM AUTHOR]
