An empirical and expert‐knowledge hybrid approach to implement farmland habitat assessment for birds

AbstractBird species survival and breeding depend on necessary abiotic and biotic components of farmland habitat. A hybrid model based on expert knowledge using Analytic Network Process (ANP) integrated with empirical data is a capable approach for conservation scientists to determine the habitat suitability for bird species. Our study assessed the suitable distribution in the ranges of farmland habitats for bird richness throughout Taiwan, focusing on the regularly occurring birds on farmlands. We established a framework for analyzing potential habitat indicators developed by expert interviews. Then, ANP was employed to compute the weight‐based priorities. By combining habitat indicators, we assessed and presented the spatial distribution of habitat suitability. The results show that southern and eastern regions of Taiwan with high habitat suitability scores cover 60,576.51 ha (27.98%) and 40,531.42 ha (30.09%), respectively. The model has an overall accuracy of 70.40%, showing a capable and reliable approach to assessing habitat suitability for bird richness on farmland. Our study highlights a valuable tool for the policy‐makers through exploring suitable farmland habitat spots, where further conservative practices and prudent biodiversity management should be applied.

Combining the traditional craft of twined flower making with stone

Twined flower making has been a handicraft practiced by women since the Qing Dynasty (1885–94) in which wires, papers and silk threads are the main materials used by entwining the materials together in various combinations into the forms of flowers. However, the rise of plastic flowers in the 1970s, the evolution of lifestyle and weakened folk traditions has led to the gradual decline of twined flower craft. The craft of twined flower making has not been taught in a systematic fashion and thus is more difficult to pass onto new generations. The research aims to bring the art of twined flower into daily life to continue the future of this craft. The eastern region of Taiwan has an abundance of stone resources. The conception of the project is to unite the contrasting materials of twined paper flowers and to augment the scope of the craft. Traditionally twined flower handicraft has been applied mostly as an ornament or fashion accessory for women. The project extends the craft to the context of stationery by combining features found in traditional Chinese painting to produce a modern object.

Association Between Prenatal Exposure to Metals and Atopic Dermatitis Among Children Aged 4 Years in Taiwan

The prevalence of atopic dermatitis has substantially increased in recent decades, and atopic dermatitis could lead to allergic airway inflammation later in life. A previous study found that inorganic arsenic exposure was associated with allergic airway inflammation in children aged 8 to 14 years. However, the association between prenatal exposure to arsenic and other metals and the risk of atopic dermatitis among young children remains unknown. To assess the association between prenatal exposure to arsenic and other metals and the occurrence of atopic dermatitis in children at age 4 years. In total, 1152 pregnant women were enrolled in the original Taiwan Maternal and Infant Cohort Study (TMICS), a multicenter birth cohort study conducted at 9 hospitals in northern, central, southern, and eastern Taiwan from October 2012 to May 2015. Of those, 586 mothers and children aged 4 years participated in follow-up questionnaire interviews from August 2016 to January 2019. After excluding 216 participants with missing data, the final statistical analysis of follow-up data included 370 mother and child pairs from the central and eastern regions of Taiwan. Data were analyzed from February 2 to August 12, 2021. Arsenic, cadmium, lead, cobalt, copper, nickel, thallium, and zinc during pregnancy. The outcome was parent-reported atopic dermatitis history among children aged 4 years. The presence of atopic dermatitis was defined as a positive response to the question, "Has your child ever had atopic dermatitis diagnosed by a physician?" During the initial TMICS study period, concentrations of arsenic, cadmium, lead, cobalt, copper, nickel, thallium, and zinc were measured in maternal urine during the third trimester of pregnancy using an inductively coupled plasma mass spectrometer. Estimated total inorganic arsenic exposure was calculated using a model that included data on both total arsenic and arsenic species (arsenite, arsenate, monomethylarsonate, and dimethylarsenate) obtained from a previous TMICS cohort. Among 370 children included in the analysis, the mean (SD) age was 3.94 (0.59) years; 208 children (56.2%) were male, and 267 children (72.2%) were from the central region of Taiwan. A total of 110 children (29.7%) had atopic dermatitis at age 4 years. Maternal estimated total inorganic arsenic exposure during pregnancy was associated with increased odds of atopic dermatitis among children at age 4 years (odds ratio [OR], 2.42 [95% CI, 1.33-4.39] for every doubled increase of total inorganic arsenic) after adjusting for parental allergies, child's sex, geographic area, maternal educational level, and exposure to tobacco smoke. Every increased unit in the weighted quantile sum index of maternal metal exposure was significantly associated with atopic dermatitis (OR, 1.63; 95% CI, 1.28-2.07). Arsenic (40.1%) and cadmium (20.5%) accounted for most of the metal mixture index. This cohort study found that prenatal exposure to inorganic arsenic and coexposure to inorganic arsenic and cadmium were associated with a higher risk of atopic dermatitis in young children. These findings suggest that prevention of exposure to inorganic arsenic and cadmium during pregnancy may be helpful for the control of atopic dermatitis and other potential allergies in children.

Maternal Age, the Disparity across Regions and Their Correlation to Sudden Infant Death Syndrome in Taiwan: A Nationwide Cohort Study.

Sudden infant death syndrome (SIDS) has always been a regrettable issue for families. After sleeping in the supine position was proposed, the incidence of SIDS declined dramatically worldwide. However, SIDS still accounts for the top 10 causes of infant deaths in Taiwan. Recognizing the risk factors and attempting to minimize these cases are imperative. We obtained information on cases with SIDS from the National Health Insurance Research Database in Taiwan and interconnected it with the Taiwan Maternal and Child Health Database to acquire infant–maternal basal characteristics between 2004 and 2017. The SIDS subjects were matched 1:10 considering gestational age to normal infants. After case selection, a total of 953 SIDS cases were included. Compared with healthy infants, SIDS infants had younger parents, lower birth weight, and lower Apgar scores. After adjusting for potential confounders, infants with mothers aged <20 years had 2.81 times higher risk of SIDS. Moreover, infants in the non-eastern region had a significantly lower risk of SIDS than those in the eastern region. We concluded that infants of young mothers (especially maternal age <20 years) and infants in the eastern region of Taiwan had a higher risk of SIDS than their counterparts.

The status of hospital dentistry in Taiwan in October 2019

Background/purposeDental care has been officially incorporated into the hospital accreditation system in Taiwan since 2015. The geographical distribution of dentist manpower still remains in an unbalanced status as shown by the dentist-to-population ratio. This study tried to assess the dental manpower issue in terms of the status of hospital dentistry, and hence provided two organizational-level suggestions with their policy implications. Materials and methodsThis study utilized the secondary data analysis to evaluate the dental manpower in dental departments of medical centers, regional hospitals, and district hospitals in different regions of Taiwan in October 2019. ResultsOur results found that the dental manpower including the numbers of general dentists and dental specialists was highest in medical centers, followed by regional hospitals and district hospitals. Moreover, the dental resources and manpower were mostly concentrated in the northern region of Taiwan, followed by the central and southern regions of Taiwan, the eastern region of Taiwan, and offshore islands. ConclusionThe hospital dentistry in Taiwan develops toward large-scale and specialization. Both hospital general dentists and dental specialists are concentrated in the medical centers, especially the medical centers in the northern region of Taiwan, indicating the problem of oversupply in the northern Taiwan and unbalanced distribution of dentists among the regions in Taiwan. Therefore, the responsibilities of the hospitals in metropolitan areas are to develop the elderly and disabled dentistry and to assist with oral health promotion and oral disease prevention in remote areas to reduce the urban-rural gap in dental resources in Taiwan.

The perceived neighborhood environment is associated with health-enhancing physical activity among adults: a cross-sectional survey of 13 townships in Taiwan

BackgroundMany environmental factors have been associated with physical activity. The environment is considered a key factor in terms of the rate of engagement in physical activity. This study examined the perceived effect of environmental factors on different levels of health-enhancing physical activity among Taiwanese adults.MethodsData were collected from 549 adults aged at least 18 years from the northern, central, southern and eastern regions of Taiwan. Physical activity was measured using the International Physical Activity Questionnaire (IPAQ) showcard version, and participants were divided into three categories: those who performed low-, moderate-, or high-levels of physical activity, as suggested by the IPAQ scoring protocol. The perceived neighborhood environment in relation to physical activity was adapted from the Physical Activity Neighborhood Environment Scale. A multinomial logistic regression was conducted to ascertain associations between individual perceptions of the neighborhood environment and different physical activity levels.ResultsRespondents who perceived their neighborhood environment as having easy access to services and stores, and higher traffic safety were more likely to be moderate level of physical activity (odds ratio [OR]: 1.90, 95% confidence interval [CI]: 1.07–3.37; OR: 1.77, 95% CI: 1.12–2.80). The perception of having easy access to services and stores and seeing many physically active people in the neighborhood were both positively associated with a high level of physical activity (OR: 2.25, 95% CI: 1.01–5.01; OR: 2.40, 95% CI: 1.11–5.23).ConclusionsDifferent perceived neighborhood environmental factors were associated with moderate and high levels of physical activity, respectively. These findings highlight the importance of an activity-friendly neighborhood environment to stimulate engagement in physical activity among adults in Taiwan. Therefore, policies and programs should focus on improving friendliness and diversity in neighborhoods to facilitate individuals’ transitions from inactive to active lifestyles.

Trends of participation of post-graduate year training program for dentists in Taiwan dental training institutions from 2010 to 2018

Background/purposeThe licensed dentists in Taiwan should join the post-graduate year training program for dentists (PGYD) since 2010. This study aimed to analyze the project types and the geographical distribution of the PGYD training institutions in Taiwan from 2010 to 2018. Materials and methodsFrom 2010 to 2018, 735 hospitals and clinics participated in four types of PGYD project including hospital as the single training institution (project A), clinic as the single training institution (project B), hospital as the main training institution in the joint training group (project C), and clinic as the main training institution in the joint training group (project D). The project types and the geographical distribution of the training institutions were analyzed. ResultsThe 735 PGYD training projects were proposed by the 735 dental institutions. The project number grew from 119 in 2010 to 195 in 2018. The most common project type was project B (307, 41.8%), followed by the project A (249, 33.9%), the project D (101, 13.7%), and the project C (78, 10.6%). Geographically, these 735 main training institutions were located most commonly in northern region of Taiwan (379, 51.6%), followed by the central region of Taiwan (171, 23.3%), southern region of Taiwan (156, 21.2%), and eastern region of Taiwan (29, 3.9%). ConclusionHospital or clinic as the single training institution is the two most common PGYD project types in Taiwan from 2010 to 2018. These single or main dental training institutions are mainly located in the northern, central, and southern regions of Taiwan.

Epidemiological Features of Japanese Encephalitis in Taiwan from 2000 to 2014.

The incidence of Japanese encephalitis (JE) decreased sharply after the national vaccination program was implemented in Taiwan in 1968. However, cases of JE still occur. The purpose of this study was to assess the epidemiology and vaccination policy for JE in Taiwan. We analyzed the data on JE cases reported to the Taiwan Centers for Disease Control (Taiwan CDC) between 2000 and 2014. During the 15-year study period, a total of 4,474 cases were reported to the Taiwan CDC. Of these, 379 (8.5%) were classified as confirmed cases, and 4,095 (91.5%) were classified as suspected cases. The incidence of JE ranged from 0.59 to 1.61 per 1,000,000 people and peaked in 2007. Men had a higher incidence of JE than women (1.37 versus 0.84 per 1,000,000; P = 0.03). Patients who were 40-59 years of age had a higher incidence than did patients younger than 20 years (1.82 versus 0.23; P < 0.001). Patients who lived in the eastern region of Taiwan had the highest incidence rate of JE (P < 0.001). Compared with those who were not vaccinated with the JE vaccine, patients who received four doses of JE vaccine had a lower risk of suffering from death and/or hospitalization (adjusted odds ratio: 0.26; 95% confidence interval: 0.08-0.90; P = 0.04). JE is still a public health problem in Taiwan, and monitoring JE via diagnostic testing to determine the best vaccination program along with enforcing JE vaccine boosters for adults is necessary to eliminate JE in Taiwan.

Cubitanoids and Cembranoids from the Soft Coral Sinularia nanolobata

Two new cubitanoids, nanoculones A and B (1 and 2), and three new cembranoids, nanolobols A–C (3–5), as well as six known compounds, calyculone I (6), sinulariuol A (7), sinulariols C, D, H, and J (8–11), were isolated from the soft coral Sinularia nanolobata, collected off the coast of the eastern region of Taiwan. Their structures were elucidated on the basis of extensive spectroscopic analysis. Cytotoxicity of compounds 1–11 was evaluated. The nitric oxide (NO) inhibitory activity of selected compounds was further measured by assay of lipopolysaccharide (LPS)-stimulated NO production in activated RAW264.7 cells. The results showed that none of 1–11 exhibited cytotoxicity against the tested cancer cell lines, whereas compound 8 was found to significantly reduce NO production.

The lived experiences of aboriginal adolescent survivors of childhood cancer during the recovering process in Taiwan: A descriptive qualitative research.

The purpose of this study was to understand the experiences of Taiwanese aboriginal adolescent survivors of childhood cancer during the process of recovery. A snowball sampling strategy was used to recruit participants from the pediatrics unit of a medical center in the eastern region of Taiwan. In-depth interviews were conducted with 11 aboriginal adolescent childhood cancer survivors. The data were analyzed using content analysis. The results revealed three major themes with subthemes within each theme. The three major themes are: roots of resilience, transformation and growth, and meaning of traditional rituals for resilience. The three subthemes within "roots of resilience" include: "feeling secure through company of family, care and financial support", "receiving support from the important others and religion" and "learning to self-adjust". The three subthemes revealed within "transformation and growth" are: restructuring the relationship with peers, "appreciating parents' hard work", and "learning to seize the moment". The two subthemes within "meaning of traditional rituals to resilience" include: "feeling blessed with the power of ancestral spirits" and "strengthening ethnic identity". This study provided insight into the experiences of aboriginal adolescents as they recovered from childhood cancer. The experiences made positive impacts by inspiring growth in maturity and consolidating aboriginal ethnic identity. The adolescents were empowered by support from family, friends and clansmen, and by their participation in aboriginal rituals. As healthcare professionals care for the aboriginal adolescents, it is critical to consider this culturally and ethnically specific knowledge/experience of surviving cancer to improve quality of care.

Improving the management of commercial giant mottled eel Anguilla marmorata aquaculture in Taiwan for improved productivity: a bioeconomic analysis

A multivariate statistical analysis was conducted with the aim to identify the key factors affecting the profitability of commercial aquaculture of the giant mottled eel Anguilla marmorata on Taiwan. The results revealed significant differences between the different fish farming systems used on Taiwan in terms of sustainable and profitable commercial enterprise. In terms of production costs, the water circulation systems accounts for the highest costs in water production, and feed costs account for 82.3 % of the total production cost. However, the survival rate is low, about of 20–30 %. Eels were cultured for 2–3 years before a market profit was reached. The farming system in the eastern region of Taiwan had the lowest production cost. The benefit–cost ratio of the concrete pond in the central region of Taiwan and the soil pond in the eastern part of Taiwan was the highest, at about 2.6, and profitability was relatively good; however, the farming cycle is longer and the production risk is higher. These results also show that the survival rate is significantly correlated to production efficiency. Consequently, based on our analysis, we suggest that strengthening cultivation techniques, appropriately increasing stocking density and segmenting glass eels farming in terms of nursery rearing and grow-out will reduce the production risk and enhance the profitability of the industry.

Polybrominated Diphenyl Ethers in Foodstuffs from Taiwan: Level and Human Dietary Exposure Assessment

Polybrominated diphenyl ethers (PBDEs) may contaminate food through bioconcentration and biomagnification. PBDEs often exist in the food chain and are consumed by humans. This study aims to determine the concentrations of PBDEs in food intake and to estimate the daily exposure of Taiwanese citizens to PBDEs. One hundred and eight food samples from nine types of commonly consumed foodstuffs were collected from northern, central, southern, and eastern regions of Taiwan. The samples were analyzed for PBDE level by gas chromatography mass spectrometry. Also, a daily dietary intake survey was conducted of 466 adults (153 men, 313 women) in these four regions of Taiwan. Taiwanese daily dietary intake of PBDE is calculated by means of food PBDEs level and daily dietary intake. The result of this study showed the highest concentration of ΣPBDE was found in butter (890.3±309.0pg/g wet weight), followed by egg and pork (553.0±185.0pg/g wet weight and 545.4±181.0pg/g wet weight). Deca-BDE was found the highest concentration among eight kinds PBDEs. The average daily intake of PBDEs for the 466 subjects was 67.95±23.01ng/day. There was a significant difference between the daily intake of ΣPBDE in different regions of Taiwan (p<0.05). The highest daily intake of ΣPBDE was in northern Taiwan, which is also the most urbanized area.

Appropriateness of ambulatory prescriptions in Taiwan: translating claims data into initiatives

Appropriate prescribing is fundamental to successful pharmacotherapy. The status of current ambulatory medication practices in medicine and pharmacy would be better understood through an analysis of community pharmacy prescription claims. The aims of the study were to investigate patterns of the types of prescriptions claimed by community pharmacies, undetected prescription errors by community pharmacists, and associated factors of prescription errors. A population-based claims database of prescriptions dispensed by community pharmacies in Taiwan. Ambulatory prescriptions were randomly sampled and reassessed for prescribing appropriateness by medical center pharmacists using explicit criteria. Demographics of patients, physicians, care facilities, and prescription/dispensing details were assessed and used to identify associated factors for prescription errors using descriptive analyses as well as logistic regression. Erroneous prescriptions prescribed by physicians, and dispensed and claimed through community pharmacies. The study included analyses of 3065 prescriptions dispensed in community pharmacies resulting from 1003 patient visits, mostly to physician or dental clinics (99.5%). Prescribing characteristics, patterns, and examples of prescription errors are described. Prescription errors were identified in 18.3% (n = 560) of prescriptions and 34.9% (n = 350) of patient visits. Potential prescribing errors included errors of omission (25.5%), errors of commission (53.4%), and others (21.1%). The top three errors were incorrect dosage (27.5%), missing indication (23.6%), and insufficient or unavailable drug information (18.9%). Drugs most frequently associated with prescription errors included antihistamines, hormones, and gastrointestinal agents. Prescription were also higher in the central and eastern regions of Taiwan. Pediatricians accounted for a disproportionate number of prescription errors. Prescription errors are prevalent in ambulatory care in Taiwan, and differential practice standards exist between community and hospital services. This disparity needs to be reconciled by pertinent initiatives to enhance community-hospital and pharmacist-general practitioner communication and interprofessional educational efforts to improve medication use and safety.

Developing regional cooperation strategies by multi-criteria decision making approaches

Based on the regional cooperation policy outlined in the National Land Plan of Japan, this study developed a regional cooperation planning model (RCPM) for use by regional planners and researchers. RCPM includes two sub-models. The first sub-model is the local service evaluation model (LSEM), which employs grey multiple criteria evaluation to assess local services for individual cities, towns and villages. The second sub-model is the cooperative partner assignment model (CPAM), which applies grey multiple objective 0–1 programming to determine optimal cooperative partners for individual cities, towns and villages. Applying RCPM to eastern Taiwan yielded the following conclusions. First, the current division of Living Perimeters in the Eastern Taiwan Region should be adjusted according to the analytical results presented in this study to reach further benefits of cooperation. Second, since RCPM uses grey numbers to display input data and research findings, it provides planning flexibility and resolves uncertainties in practical planning. Finally, the modeling results contribute to cooperative strategy development among neighboring areas in an underdeveloped region.

In vivo and in vitro studies to identify the hypoglycaemic constituents of Momordica charantia wild variant WB24

Wild bitter melon (the wild variant of Momordica charantia L.) native to the eastern region of Taiwan has been consumed by local residents as a folk medicine for the prevention or treatment of hyperglycaemia and related diseases, yet its hypoglycaemic activities and constituents have not been scientifically characterised. Thus, WB24, a strain of wild bitter melon originating from the eastern region of Taiwan, was investigated. By cell-based screening, the fruit of WB24 was revealed to be a rich source of hypoglycaemic molecules, and the in vivo hypoglycaemic activities of selected fractions were assessed. Five triterpenes were isolated from one of the most active fractions and their ability to activate AMP-activated protein kinase (AMPK) was observed. One triterpene of the five analysed exhibited the highest activation of AMPK in an insulin-independent manner, and the AMPK-activation activity of this triterpene was greater than that of troglitazone, a thiazolidinedione-type antidiabetic medicine.

Comparative epidemiology of betel nut use versus ecstasy use among Taiwanese adolescents: Findings from a national survey

Aims To investigate whether variation may exist in betel nut- and ecstasy-involved adolescents in terms of sociobehavioral characteristics, the experience of psychoactive substance use, and behavioral/emotional problems. Methods Students ( n = 53,528) aged 12–18 sampled via stratified, multistage, random cluster sampling in 2004, 2005, and 2006 throughout Taiwan were categorized into four groups: betel nut- and ecstasy-naïve ( n = 51,009), betel nut use only ( n = 1965), ecstasy use only ( n = 196), and use of both ( n = 152). Participants completed a questionnaire with information on sociodemographic features, substance-use experiences, and the Chinese adaptation of the Youth Self Report. Results Having a job, a larger weekly allowance, truancy, sexual experience, and externalizing behaviors were all in strong association with the involvement of either betel nut or ecstasy use. Compared with ecstasy-only users, betel nut-only users were more likely to be male, from the Eastern region of Taiwan, with initiation motivated by family members or friends, and having excess risks for Anxiety/Depression, Thought Problems, and Attention Problems. In contrast, ecstasy-only users were more likely to be female and involved in using other illegal drugs, with their initiation motivated by entertainment and with the drug use taking place in such settings. Conclusions The variation in the experience of psychoactive substance use and behavioral problems for betel nut and ecstasy users suggests the existence of subgroups of drug-using adolescents in Taiwan. The identification of such heterogeneity may guide the efforts to reduce substance use and develop subgroup-tailored preventive programs.

Rainwater harvesting in schools in Taiwan: system characteristics and water quality

In order to understand the current status of rainwater harvesting (RWH) practices in Taiwan's schools, a study was carried out to examine the RWH system performance, water usage, and water quality in these sites. A total of 29 schools in various regions were selected for this investigation, including 7 in the northern, 7 in the central, 8 in the southern, and 7 in the eastern regions of Taiwan. Water quality indicators tested were: pH, temperature, conductivity, oxidation-reduction potential, suspended solid, total organic carbon, fecal coliform, and total coliform. From this study, it was found that RWH systems in these sites generally had two different designs: one that collected rainwater only, and one that collected both rainwater and grey water. From statistical analysis, it was found that water quality indicators such as suspended solids, total organic carbon, and fecal coliform were significantly affected by the water source and site location. Fecal coliforms in most of the sites we studied were high and not qualified for toilet flushing. The average water retention time of 2.4 months was long and considered to be the main reason to cause high fecal coliform counts. Finally, the benefit analysis was conducted to evaluate economic feasibility of rainwater harvesting for these schools. It turned out that 20% of them were able to gain economic benefits from using rainwater.

Betel Nut Chewing Behavior among Adolescents in Eastern Taiwan: A Cluster Analysis

The prevalence of betel nut chewing among junior high school students is highest in the eastern region of Taiwan (Lin, 1990). Although there is some research on the prevalence rate, little effort has been paid to developing a classification of betel nut chewing behavior applicable to adolescents. Eight-hundred and forty-three students, including 435 males (51.6%) and 408 females (48.4%), 552 non-aborigines (65.5%) and 291 aborigines (34.5%), completed a questionnaire concerning betel nut chewing behavior, beliefs (perceptions) toward betel nut chewing, self-esteem, and locus of control. Using a cluster analysis, this study identified 3 sub-types ofbetel nut chewing behaviors. They were identified as "Self-regulation oriented" (Internally controlled-oriented), "Indigenously oriented" (Taiwan culture-oriented), and "Symbolically oriented" (Externally controlled-oriented). The validity of clusters was explored in terms of gender and ethnicity. This study describes the implications for reducing betel nut chewing behaviors among adolescents.

Does Problem Solving = Prior Knowledge + Reasoning Skills in Earth Science? An Exploratory Study

This study examined the interrelationship between tenth-grade students’ problem solving ability (PSA) and their domain-specific knowledge (DSK) as well as reasoning skills (RS) in a secondary school of Taiwan. The PSA test was designed to emphasize students’ divergent-thinking ability (DTA) and convergent-thinking ability (CTA) subscales in the area of Earth science. Two hundred and sixty tenth graders who were enrolled in six Earth science classes at a public senior high school located in the eastern region of Taiwan were participants. Major findings are as follows: (a) A significantly positive correlation existed between students’ PSA and their DSK and RS, approaching large effect sizes; (b) Both students’ DSK and RS significantly explained the variance of their PSA with large effect sizes; (c) Students’ RS could more significantly explain the variance of their DTA subscale with medium effect size while DSK might more significantly explain the variance of their CTA, approaching large effect size. The research suggests that more emphasis should be placed on the reasoning skills when developing students’ divergent-thinking abilities, while stressing more domain-specific knowledge when students’ convergent-thinking ability is considered.

Isolation and characterization of microsatellite loci in the endangered freshwater fish Varicorhinus alticorpus (Cyprinidae)

Varicorhinus alticorpus (Cyprinidae) is an endangered freshwater fish with a scattered distribution in the southern and eastern regions of Taiwan. We described the development of nine polymorphic microsatellite loci in V. alticorpus for genetic studies. These new markers were tested in 20 individuals of the rare species. The number of alleles ranged from 4 to 13. Expected (HE) and observed (HO) heterozygosities ranged from 0.692 to 0.892 (averaged at 0.821) and from 0.000 to 0.350 (averaged at 0.088), respectively. All loci are significantly deviated from Hardy–Weinberg expectations due to the heterozygote deficiency. This suite of highly polymorphic microsatellites provides the first chance to undertake a conservation program for this species in Taiwan. It is essential to evaluate its genetic diversity and the fine-scale population structure.
