Purpose - Enterprises must select the best optimal endorser-product fit in order to maximize the limited budget available for endorsements. Previous studies have determined that the influence of athlete endorsers is greater than is that of celebrity endorsers on consumer attitudes toward sport products. However, different endorsers may possess different levels of influence on products. The paper aims to discuss these issues. Design/methodology/approach - This study developed two field experiments to investigate the influence of endorser-product fits on consumer purchase intentions. Participants in Study 1 were 295 individuals (220 male consumers, 75 female consumers, M age=32 yr) in the two Baseball Stadiums in Taiwan. Participants in Study 2 were 317 EMBA students (204 men, 113 women, M age=34 yr) at a certain university in Taiwan. Findings - The results determined no significant moderating effect of celebrity endorser-product fit and purchase intention, whereas athlete endorser-product fit enhanced consumers' purchase intentions in low product involvement scenarios. In high product involvement scenarios, a moderating relationship between endorser-product fit and purchase intentions was observed. These findings can provide a reference regarding endorsers and product patterns for enterprises to maximize the value of endorsers. Originality/value - Using the multiple endorser-product patterns, this study provides useful findings in terms of the perceived value of endorser-product and purchase intention. The results of this study can help enterprises to choose the most suitable endorser when they are subject to budget constraints. Detailed descriptions of the expected results and discussion are reported in the text. [ABSTRACT FROM AUTHOR]

OBJECTIVES: To analyze Australian national data to examine the impact of the coronavirus disease 2019 (COVID-19) pandemic on mental health-related hospital presentations among children and adolescents during the pandemic period with restrictions, and the period after the restrictions eased. METHODS: We analyzed the monthly mental health-related inpatient admissions and emergency department (ED) attendances data from 6 large pediatric hospitals across Australia, using the Bayesian structural time series models. The COVID-19 restriction period was from March 2020 to December 2021 and the COVID-19 restriction-eased period from January to June 2022. RESULTS: A total of 130 801 mental health-related hospital admissions (54 907) and ED attendances (75 894) were analyzed. During the COVID-19 restriction period, there was a significant increase in inpatient admissions related to deliberate self-harm behaviors (82%, 95% credible interval [CrI], 7%-160%) and ED attendances related to overall mental health disorders (15%, 95% CrI, 1.1%-30%) and eating disorders (76%, 95% CrI, 36%-115%). The increase was higher among females and those living in the least socioeconomically disadvantaged areas, suggesting a widening gap between mental health-related presentations by sex and socioeconomic status. After the restrictions eased, there were slight declines in mental health-related hospital presentations; however, the numbers remained higher than the pre-COVID-19 levels. CONCLUSIONS: The increase in mental health-related hospital presentations during the COVID-19 period calls for additional support for pediatric mental health care, particularly for eating disorders and deliberate self-harm among female adolescents. It is important to monitor pediatric mental health service use as we enter "COVID-19 normal" period. [ABSTRACT FROM AUTHOR]

ZnxCd1-xSe alloy nanowires, with composition x 0, 0.2, 0.5, 0.7, and 1, have been successfully synthesized by a chemical vapor deposition (CVD) method assisted with laser ablation. The as-synthesized alloy nanowires, 60−150 nm in diameter and several tens of micrometers in length, complied with a typical vapor−liquid−solid (VLS) growth mechanism. The ZnxCd1-xSe nanowires are single crystalline revealed from high-resolution transmission electron microscopic (HRTEM) images, selected area electron diffraction (SAED) patterns, and X-ray diffraction (XRD) measurement. Compositions of the alloy nanowires can be adjusted by varying the precursor ratios of the laser ablated target and the CVD deposition temperature. Crystalline structures of the ZnxCd1-xSe nanowires are hexagonal wurtzite at x 0, 0.2, and 0.5 with the 0 1 −1 0 growth direction and zinc blende at x 0.7 and 1 with the 1 −1 1 growth direction. Energy gaps of the ZnxCd1-xSe nanowires, determined from micro-photoluminescence (PL) measurements, change nonlinearly as a quadratic function of xwith a bowing parameter of ∼0.45 eV. Strong PL from the ZnxCd1-xSe nanowires can be tuned from red (712 nm) to blue (463 nm) with xvarying from 0 to 1 and has demonstrated that the alloy nanowires have potential applications in optical and sensory nanotechnology. Micro-Raman shifts of the longitudinal optical (LO) phonon mode observed in the ZnxCd1-xSe nanowires show a one-mode behavior pattern following the prediction of a modified random element isodisplacement (MREI) model.

Previous evidence suggests that the inheritance of bipolar disorder (BP) may vary depending on the age at onset (AAO). Therefore, we sought to incorporate AAO as a covariate in linkage analyses of BP using two different methods, LODPAL and ordered-subset analysis (OSA), in genomewide scans of 150 multiplex pedigrees with 874 individuals. The LODPAL analysis identified two loci, on chromosomes 21q22.13 (LOD = 3.29; empirical chromosomewide P value = .009) and 18p11.2 (LOD = 2.83; empirical chromosomewide P = .05), with increased linkage among subjects who had early onset (AAO ⩽ 21 years) and later onset (AAO >21 years), respectively. The finding on 21q22.13 was significant at the chromosomewide level, even after correction for multiple testing. Moreover, a similar finding was observed in an independent sample of 65 pedigrees (LOD = 2.88; empirical chromosomewide P = .025). The finding on 18p11.2 was only nominally significant and was not observed in the independent sample. However, 18p11.2 emerged as one of the strongest regions in the OSA (LOD = 2.92; empirical P = .001), in which it was the only finding to meet chromosomewide levels of significance after correction for multiple testing. These results suggest that 21q22.13 and 18p11.2 may harbor genes that increase the risks for early-onset and later-onset forms of BP, respectively. There have been previous reports of linkage on 21q22.13 and 18p11.2, but the findings have not been consistent. This inconsistency may be due to differences in the AAO characteristics of the samples examined. Future studies to fine map susceptibility genes for BP on chromosomes 21q22.13 and 18p11.2 should take AAO into account. [ABSTRACT FROM AUTHOR]
