The results of the qualitative analysis showed that there were orange spots with an Rf value of 0.64 in the carrot extract and the beta-carotene comparison standard. The results of the quantitative analysis showed that the average level of vitamin A in carrots was 49.7% with an absorbance of 0.649. Keywords: Visible Spectrophotometry, Vitamin A, Carrot.

Increasing saving intentions through leaderboards: A gamification approach

Saving money is important but challenging. To spur financial saving intentions, we propose a new strategy—gamification. Specifically, we investigate the effectiveness of competitive leaderboards in increasing individuals’ saving intentions. The results of two studies (total N = 618) show consistently that people’s saving intentions are higher when presented with a leaderboard than when not. Further, as leaderboards elicit social comparison, we explore whether the height of the comparison standard and individuals’ social comparison orientation moderate the effect. We find that the effect of leaderboards on saving intentions is more pronounced when people compare with a higher (as compared to a lower) standard (Study 1), but that the effect is not influenced by individuals’ social comparison orientation (Study 2). Taken together, this research provides a new and simple-to-implement strategy to facilitate saving intentions in order to help improve people’s financial well-being.

Validation of semiquantitative FFQ administered to adults: a systematic review

Objective: To conduct a systematic review of studies for the validation of semiquantitative FFQ (SFFQ) that assess food intake in adults. Design: The authors conducted a systematic search in PubMed for articles published as late as January 2020 in Spanish, English, French and Portuguese. Individual searches (twelve in total) paired three hyphenated and non-hyphenated variations of ‘semiquantitative food frequency questionnaire’ with both ‘validity’ and ‘validation’ using the ‘all fields’ and the ‘title/abstract’ retrieval categories. Independent extraction of articles was performed by four authors using predefined data fields. Setting: We searched for original SFFQ validation studies that analysed general diet composition (nutrients with or without food groups or energy analysis) in healthy adults, in any setting, and that also reported correlation coefficients. Participants: Healthy adults. Results: Sixty articles were included. The preferred comparison standard for validation was food records (n 37). The main correlation coefficients used were Pearson’s (n 41), and validity coefficients varied from −0·45 to 1. Most correlation coefficients were adjusted by energy (twelve studies presented only crude values). The elements mentioned most frequently were energy, macronutrients, cholesterol, SFA, PUFA, fibre, vitamin C, Ca and Fe. Conclusions: Although all these SFFQ are reported as validated, coefficients may vary across groups of foods and nutrients. Based on our findings, we suggest researchers to consult our revision before choosing a SFFQ and to review important issues about them, such as their validation, number of items, number of participants, etc. Systematic Review Registration: PROSPERO number CRD42017064716.

Interaction of insecticide and disinfectants used in a poultry house with the nematode entomopathogenic Steinernema arenarium

This study evaluated the effect of cypermethrin insecticide and disinfectants, both used in the management of poultry houses, on nematode Steinernema arenarium, as well as their effect on the bacterium symbiont of nematode. The IOBC/WPRS methodology proposed by Vainio (1992) was used to study the effect on the nematode. The solution of the product was mixed with 1ml of the nematode suspension in distilled water [2000 infective juveniles (IJs)/ml]. As control treatment, only the suspension of the nematode was used. After 48 hours, the viability and the infectivity of the nematode on the larvae of Tenebrio molitor were assayed. The effect of products on the symbiont bacterium was also evaluated. Suspension with 108 CFU (colony forming units)/mL were inoculated in culture medium and three paper discs added (control treatment – distilled water, comparison standard – neomycin, and a disc treated with each product) and the growth was evaluated after 24 hours. All the products reduced the viability of S. arenarium, although only the chlorine-based disinfectant caused reduction above 55%. For the infectivity, the chlorine-based product and the insecticide cipermil reduced in 100% this activity and were considered harmful based on E%. All the products affected the bacterial growing.

Deteksi Asam Mefenamat pada Jamu Pegel Linu yang beredar di Wilayah Pekalongan

Jamu Pegel Linu is one of the most popular herbs in Indonesia and oftenly the producers added medicinal chemicals (BKO) so that the resulting therapeutic effect is more effective. One of the BKO added is mefenamic acid. The added content of mefenamic acid can cause harmful side effects such as seizures and can even cause coma. This study aimed to detect the BKO content of mefenamic acid in Jamu Pegel Linu distributed in Pekalongan region. This research was a descriptive study with purposive sampling. The sample used was all Jamu pegel linu that were distributing in Pekalongan region that were included the inclusion and exclusion criteria. The analytical method used is Thin Layer Chromatography (TLC) with a mobile phase in the form of ethyl acetate: methanol: ammonia (80:10:10). Spotting detection was carried out under UV light at λ 254 nm. The results of the spots obtained were compared with a comparison standard. To ensure the results obtained are confirmed using the color reaction method. The results of testing of 27 samples by TLC method obtained there are 3 (three) samples of herbal medicine giving positive results indicated by the similarity of rf values with comparative standards. The results obtained were tested qualitatively with color reagents to strengthen the results.

Dispositional Greed Predicts Benign and Malicious Envy

Greed is an important precursor to envy. It is unclear, however, whether this link reflects only malicious envy, which involves hostile motivation towards superior others, or whether greed also predicts benign envy, which involves improvement motivation. If this is the case, the two forms of envy might connect greed to diverging psychological outcomes, such as differences in life satisfaction. The current research provides initial support for this possibility. In Study 1, participants (N = 296) responded to measures of dispositional greed and dispositional benign and malicious envy. Furthermore, after three weeks, participants were confronted with an upward comparison standard to assess state benign and malicious envy. As hypothesized, greed predicted more benign and more malicious envy. Furthermore, greed via malicious envy predicted lower life satisfaction, whereas via benign envy, it was connected to higher life satisfaction. Study 2 (N = 793) confirmed this pattern in a preregistered replication. These results underline the value of a more nuanced view on the relationship of greed and envy.

Potensi Ekstrak Buah Buni (Antidesma bunius (L) Spreng) Sebagai Inhibitor Enzim α-Glukosidase

Diabetes mellitus is still a global health problem that continues to increase rapidly and become one of the major metabolic diseases throughout the world. This study aims to determine the potential of Buni fruit as an α-glucosidase inhibitor. α-glucosidase inhibition test is carried out on a blank solution (test solution without sample/standard), acarbose solution as a comparison standard and samples are carried out in accordance with the optimization conditions obtained. The rendemen percent of green and red buni fruit extract yields are 6.35% and 3.09%, respectively. The results of the identification of secondary metabolites using TLC showed that green and red buni fruit extract contains flavonoid, phenolic and alkaloid compounds. The results of the α-glucosidase enzyme inhibition test showed that the red buni fruit extract had the highest activity compared to green buni fruit extract with an IC50 value of 85.27 ppm.

Basic Color Terms in Khanty

The Khanty language contains the minimum number of words ‒ color terms. For “black”, the word “pity” is used, presumably related to the single root “pătlam” “dark”, for “white” ‒ the word “nŏvi”, meaning also “light”, “moon”, for “red” ‒ the word “wŭrty” (from “wŭr” ‘blood’). One word “wŏsty” is used for the undifferentiated designation of shades of the yellow- green-blue spectrum. Currently, the differentiation of color terms is achieved by using phrases with the base word, which is a comparison standard (“blue as the sky”, “green as the grass”, etc.).
