The new species is similar to Y. bannaensis Zheng (Zheng 1995, 2005) and Y. elytratus (Günther) (Günther 1939, Shishodia 1991). it can easily distinguish from the former based on obtusely angled anterior margin of vertex and indistinct humeral angles, and from the latter by triangular concavity of apex of hind process and external lateral carina of pronotum distinctly extending backwards and reaching 3/4 of hind femur. Etymology. The new species’ epithet is derived from Latin words ‘ variabilis ’ (variable), which means structures of pronotal disc of the new species are variable in different individuals. Ecology and habitats. Individuals of Yunnantettix variabilis sp. nov. inhabited leaf litter of tropical rainforest (Doi Mae Salong) in Northern Thailand, and they prefer shades of trees instead of exposing under the sun, and live in the open air and dry place (Fig 8). They feed on humus of leaf litter. Around the localities there are no stream, and they can also adapt to drought even extreme high temperature, because one locality had burnt off seriously (Fig 8 c), and specimens collected from it resemble black carbon, which seems to having been burnt off by fire. Provided with extremely degenerate wings, they are flightless, instead with very developed hind femora, they jump rapidly for 1–2 meters. They live with Epitettix obtusus and several Bolivaritettix spp.. According to our observations and experiences, adults of the new species cannot be found after August of the year, so we infer they occur only in the dry seasons, while with the rainy season’s coming they will disappear thoroughly. From adult occurrence period and environment of inhabits, together with rotation between dry season and rainy season in Northern Thailand, we infer they reproduce one generation per one year, and they lay eggs in soil which will go through the whole rainy reason before hatching.Published as part of Zha, Lingsheng, Wen, Tingchi, Boonmee, Saranyaphat & Eungwanichayapant, Prapassorn D., 2016, Notes on the genus Yunnantettix Zheng (Tetrigidae: Cladonotinae), with descriptions of two new species from Thailand, pp. 373-385 in Zootaxa 4205 (4) on pages 381-384, DOI: 10.11646/zootaxa.4205.4.6, http://zenodo.org/record/19718
Yunnantettix thaicus Storozhenko & Pushkar 2015
No full textYunnantettix thaicus Storozhenko & Pushkar, 2015 http://lsid.speciesfile.org/urn:lsid: Orthoptera.speciesfile.org:TaxonName:470962 Notes. This species is similar to Y. nanensis sp. nov.. According to the original photographs provided (Storozhenko & Pushkar 2015): median carina of vertex not protruding forward, in lateral view vertex together with frontal costa exactly arcuate (but the original line drawing provided indicates that in lateral view vertex together with frontal costa obtusely rounded and protruding forward); posterior margin of female subgenital plate truncate (but the line drawing provided indicates posterior margin gradually contracted backwards). Notably, female size (body length, width of vertex than one eye, and lengths of both hind femur and pronotum) is smaller than male (Storozhenko & Pushkar 2015), which is unusual. In Tetrigiade, female pronotum may equal or shorter than male sometimes, such as Bolivaritettix anhuiensis Zhang, Zha & Zheng, 2014, but little is reported that female body length, width of vertex than one eye, length of hind femur are smaller or shorter than male. Considering the holotype (♂, Nakhon Ratchasima Province) and the paratype (only 1♀, Loei Province) coming from two different regions of Thailand, that are 300 km distant, their different ratios of width of scutellum between antennal grooves than diameter of first segment of antenna (male 2.5 times while female 2.0 times), together with their unusual body sizes, we doubt the two specimens may represent two different species. Shortly afterwards, Storozhenko & Dawwrueng (2015) reported another distribution of this species (1♂ 2♀, Chiang Mai Province, Thailand), but they did not give any morphological description.Published as part of Zha, Lingsheng, Wen, Tingchi, Boonmee, Saranyaphat & Eungwanichayapant, Prapassorn D., 2016, Notes on the genus Yunnantettix Zheng (Tetrigidae: Cladonotinae), with descriptions of two new species from Thailand, pp. 373-385 in Zootaxa 4205 (4) on page 377, DOI: 10.11646/zootaxa.4205.4.6, http://zenodo.org/record/19718
Impacts of Self-Efficacy on Food and Dietary Choices during the First COVID-19 Lockdown in China
No full textThe COVID-19 pandemic has caused a global public health emergency, increasing the prevalence of emotional distress, and potentially leading to altered diet behavior. Self-efficacy measures various aspects of perceiving and understanding emotions. The present study was carried out with the objective of understanding the effect of emotional self-efficacy on dietary behavior and quality. It also shed light on which elements contributed to the link between food-related behavior and perceived dietary quality during the first lockdown of the COVID-19 pandemic. Based on the factor analysis of nineteen food groups, choices, consumption, and socioeconomic status were examined in a sample of 441 Chinese participants. Multiple linear regression examined the association between food consumption, dietary quality, and self-efficacy. Contrary to prior research, the intake of salty snacks and alcoholic beverages dropped by 3.3% and 2.8%, respectively, during the first lockdown. Emotional self-efficacy negatively mediated the relationship between socioeconomic status and dietary quality. In conclusion, emotional self-efficacy is a well-established tool for evaluating
how Chinese people cope with negative emotions. As an individual’s dietary quality was affected during the imposed lockdown, the present study offers valuable insight into psychosocial factors that may contribute to health disparities by advocating for organized nutritional support in future

Obesity-Related Communication in Digital Chinese News From Mainland China, Hong Kong, and Taiwan: Automated Content Analysis
No full textBackground:
The fact that the number of individuals with obesity has increased worldwide calls into question media efforts for informing the public. This study attempts to determine the ways in which the mainstream digital news covers the etiology of obesity and diseases associated with the burden of obesity.
Objective:
The dual objectives of this study are to obtain an understanding of what the news reports on obesity and to explore meaning in data by extending the preconceived grounded theory.
Methods:
The 10 years of news text from 2010 to 2019 compared the development of obesity-related coverage and its potential impact on its perception in Mainland China, Hong Kong, and Taiwan. Digital news stories on obesity along with affliction and inferences in 9 Chinese mainstream newspapers were sampled. An automatic content analysis tool, DiVoMiner was proposed. This computer-aided platform is designed to organize and filter large sets of data on the basis of the patterns of word occurrence and term discovery. Another programming language, Python 3, was used to explore connections and patterns created by the aggregated interactions.
Results:
A total of 30,968 news stories were identified with increasing attention since 2016. The highest intensity of newspaper coverage of obesity communication was observed in Taiwan. Overall, a stronger focus on 2 shared causative attributes of obesity is on stress (n=4483, 33.0%) and tobacco use (n=3148, 23.2%). The burdens of obesity and cardiovascular diseases are implied to be the most, despite the aggregated interaction of edge centrality showing the highest link between the “cancer” and obesity. This study goes beyond traditional journalism studies by extending the framework of computational and customizable web-based text analysis. This could set a norm for researchers and practitioners who work on data projects largely for an innovative attempt.
Conclusions:
Similar to previous studies, the discourse between the obesity epidemic and personal afflictions is the most emphasized approach. Our study also indicates that the inclination of blaming personal attributes for health afflictions potentially limits social and governmental responsibility for addressing this issue

Updated. Body size small (body length 8.5–12.5 mm), head and pronotal disc covered with numerous fine granules; pronotal disc generally covered with many bulges, but few individuals relatively smooth. Vertex convex or flattened, 2.4–3.6 times as wide as an eye; anterior margin arcuate or obtusely angled, distinctly surpassing anterior margins of eyes, lateral margin little folded upwards or not; median carina conspicuous in anterior half, or protruding forward or not, while absent in posterior half, paired fossulae presented; in lateral view vertex together with frontal costa or arcuate, or obtusely rounded and protruding forward, face vertical or slightly oblique, fascial carinae between lateral ocelli or little concave or not, between antennal grooves little arcuate and protruding forward; in frontal view scutellum shallow, triangular and very wide, between antennal grooves 2.0–2.7 times as wide as diameter of scapus (1st antennal segment). Antennae filiform and short, generally 15(♂) or 16(♀) segmented, inserted between or slightly below lower margins of eyes, the longest segment 3.75–5.5 times as long as wide, coloration of distal 2–3 segments darker. Eyes globose and low, lateral ocelli situated at or slightly below the middle of inner margins of eyes. Pronotum slightly roof-like in anterior half, the posterior half nearly flattened; median carina distinct, in lateral view arcuate in anterior half, while low, undulate or straight in posterior half; anterior margin of pronotum truncated, prozonal carinae distinct, erected, or parallel or a little contracted backwards; between sulci median carina lamellate with swollen base, on both side pronotum concave. Humeral angles low, or obtusely angled or indistinct; between shoulders pronotum uplifted more or less, and paired interhumeral carinae presented on both side of median carina. Posterior angle of lateral lobe of pronotum extending oblique backwards, apex truncate and anterior margin of apex rounded; posterior margin of each lateral lobe with two concavities. Hind process wedged and wide, reaching knees or slightly beyond apex of hind femora, apex straight, concave, or obtusely rounded. Tegmen ovate; hind wing vestigial and invisible, triangular, partial or wholly covered by tegmen; visible part of tegmen narrow and long, sometimes also invisible. Fore and mid femora compressed, lower margins of fore and mid femora undulate; hind femur very stout, 2.3–3.0 times as long as wide, upper and lower margins entire or margined with indistinct small denticles; first segment of hind tarsus 1.75–2.3 times as long as third. Male subgenital plate short, cone-shaped, nearly as long as wide, apex fissured, generally upper apex on both sides forming into a pair of very short and small spines; female subgenital plate also nearly as long as wide, posterior margin truncate and in the middle with a broad triangular protrusion. Relationship to other genera. The genus Yunnantettix Zheng was placed in Cladonotinae (Tetrigidae) based on: 1) filiform antennae; 2) medial ocellus situated below lower margins of eyes; 3) dorsal margin of fore and mid femora without a furrow; and 4) fascial carina enclose a broadened scutellum (2.0–2.7 times wider than diameter of scapus). Yunnantettix is similar to the genera Pseudepitettix Zheng and Aspiditettix Liang, while Pseudepitettix is very similar to the genus Epitettix Hancock (Hancock, 1907; Shishodia, 1991; Zheng, 1995; Liang et al., 2009; Storozhenko & Pushkar, 2015, Zheng & Lin, 2016). In order to clarify the taxonomic confusions among these allied genera, we give an overall comparison to their morphologic differences as in Table 1. According to Table 1, Yunnantettix differs from Pseudepitettix by: 1) posterior margin of each lateral lobe of pronotum present two concavities; 2) tegmina generally visible; and 3) pronotum covered with many bulges. Yunnantettix can easily be separated from Aspiditettix by extremely degenerate tegmina and wings, and not elongate third segment of hind tarsus. While Pseudepitettix differs from Epitettix generally only depending on ratio of width of scutellum between antennal grooves than diameter of scapus.Published as part of Zha, Lingsheng, Wen, Tingchi, Boonmee, Saranyaphat & Eungwanichayapant, Prapassorn D., 2016, Notes on the genus Yunnantettix Zheng (Tetrigidae: Cladonotinae), with descriptions of two new species from Thailand, pp. 373-385 in Zootaxa 4205 (4) on pages 374-375, DOI: 10.11646/zootaxa.4205.4.6, http://zenodo.org/record/19718
Predicting and Empowering Health for Generation Z by Comparing Health Information Seeking and Digital Health Literacy: Cross-Sectional Questionnaire Study
No full textBackground: Generation Z (born 1995-2010) members are digital residents who use technology and the internet more frequently than any previous generation to learn about their health. They are increasingly moving away from conventional methods of seeking health information as technology advances quickly and becomes more widely available, resulting in a more digitalized health care system. Similar to all groups, Generation Z has specific health care requirements and preferences, and their use of technology influences how they look for health information. However, they have often been overlooked in scholarly research.
Objective: First, we aimed to identify the information-seeking preferences of older individuals and Generation Z (those between the ages of 18 and 26 years); second, we aimed to predict the effects of digital health literacy and health empowerment in both groups. We also aimed to identify factors that impact how both groups engage in digital health and remain in control of their own health.
Methods: The Health Information National Trends Survey was adopted for further use in 2022. We analyzed 1862 valid data points by conducting a survey among Chinese respondents to address the research gap. A descriptive analysis, 2-tailed t test, and multiple linear regression were applied to the results.
Results: When compared with previous generations, Generation Z respondents (995/1862, 53.44%) were more likely to use the internet to find out about health-related topics, whereas earlier generations relied more on traditional media and interpersonal contact. Web-based information-seeking behavior is predicted by digital health literacy (Generation Z: β=.192, P<.001; older population: β=.337, P<.001). While this was happening, only seeking health information from physicians positively predicted health empowerment (Generation Z: β=.070, P=.002; older population: β=.089, P<.001). Despite more frequent use of the internet to learn about their health, Generation Z showed lower levels of health empowerment and less desire to look for health information, overall.
Conclusions: This study examined and compared the health information–seeking behaviors of Generation Z and older individuals to improve their digital health literacy and health empowerment. The 2 groups demonstrated distinct preferences regarding their choice of information sources. Health empowerment and digital health literacy were both significantly related to information-seeking behaviors
