China’s Hengduan Mountain region has been considered one of the most diverse regions in the northern hemisphere. Its stunning topography with many deep valleys and impassable mountain barriers has promoted an astonishing diversification in many groups of organisms including plants, birds, mammals, and amphibians. However, the insect biodiversity in this region is still poorly known. Here, the first checklist of ant species from the Southern Hengduan Mountain region is presented, generated by sampling ant diversity using a wide array of collection methods, including Winkler leaf litter extraction, vegetation beating, and hand collection. 130 species/morphospecies from nine subfamilies and 49 genera were identified. Among them, 17 species from 13 genera represent new records for Yunnan province, and eight species are newly recorded for China. Moreover, we believe 41 novel morphospecies (31% of the total collected taxa) will prove to be new to science. These results highlight the rich ant fauna of this region and strongly support its status as a biodiversity hotspot. The current ant species checklist for the whole of Yunnan Province was updated by recording 550 named species from 99 genera. Taken together, our results suggest that the Yunnan ant fauna still remains under-sampled, and future sampling will likely yield many more species, among them many undescribed ones.

Ant diversity was studied in Muhan Pokhari area of Shivapuri-Nagarjun National Park (SNNP)at 1,700 m to 1,900 m asl during winter and summer seasons of 2017. Ants were collected using pitfall traps, leaf litter sampling, bait and hand collection methods along a transect of50 m in each of all 5 sites (1,700 m, 1,750 m, 1,800 m, 1,850 m and 1,900 m). Altogether 817individual ants were collected representing 5 sub-families, 16 genera and 23 morpho species. Formicinae (57.67%) was the most abundant sub-family, followed by Myrmicinae (40.39%), Pseudomyrmicinae (0.8%), Ponerinae (0.73%) and Dolichoderinae (0.37%). Camponotus (437individuals) was the most abundant genus followed by Aphaenogaster (287). Species richness was higher in winter (17 morph species) than in spring (14 morph species). Shannon-Wiener diversity index (1.4618) and Evenness index (0.5539) were higher in spring season. Pitfall trap method was found most effective with highest number of individual ants (567) and of 21 species. The Shannon-Weiner diversity index was highest for pitfall method (1.3039) whereas evenness index was highest for the bait method (0.62615). Two genera Pachycondylaand Echinopla were recorded for the first time in Nepal.

SummarySerial quantitative immunoelectrophoretic (IE) measurements of antithrombin III heparin cofactor (AT III) were made in groups of well and sick newborn infants classified by gestational age. Collection methods (venous vs. capillary) did not influence the results; serum IE measurements were comparable to AT III activity by a clotting method. AT III is gestational age-dependent, increasing from 28.7% of normal adult values at 28-32 weeks to 50.9% at 37-40 weeks, and shows a gradual increase to term infant levels (57.4%) by 3-4 weeks of age. Infants with the respiratory distress syndrome (RDS) show lower levels of AT III in the 33-36 week group, 22% vs. 44% and in the 37-40 week group, 33.6% vs. 50.9%, than prematures without RDS. Infants of 28-32 week gestational age had only slight differences, RDS = 24%, non-RDS = 28.7%. The lowest levels of AT III were seen in patients with RDS complicated by disseminated intravascular coagulation and those with necrotizing enterocolitis. Crossed IE on representative infants displayed a consistent pattern which was identical to adult controls except for appropriate decreases in the amplitude of the peaks. The thrombotic complications seen in the sick preterm infant may be related to the low levels of AT III.

This study aimed to examine the effect of demographic factors and organizational climate on the intention of internal whistleblowing. The sample was an accountant who had worked as an auditor. Data collection methods using questionnaires with financial statement fraud case scenarios. This research use ANOVA data analysis method to examine demographic factors include age, gender, and experience, as well as organizational climate on the intention of internal whistleblowing. The results showed only the experience of demographic factors that influence internal whistleblowing. Besides internal whistlelowing also influenced by organizational climate in the company.Keyword: Demographics, Organizational Climate, Whistleblowing

This article aims to look at how to improve self-efficacy through guidance and counseling services at SMP 1 Pleret, Yogyakarta. This type of research is qualitative descriptive, data collection methods through interviews and observations. Data analysis techniques using data reduction, data presentation and drawing conclusions. Results and discussion that there are still many students who have low self-efficacy so they are difficult to achieve good learning outcomes. This is proven by some students rarely doing school work and rarely doing homework also do not have the motivation to excel. BK teachers try through guidance and counseling services in the form of a preventive approach for those with high self-efficacy and a curative approach for students with low self-efficacy. Such as helping students to convince themselves that students are able to do tasks even though it is difficult and able to excel and to convince students to avoid feeling inferior about themselves. Guidance and counseling provided by BK teachers shows significant changes in some students who already have high self-efficacy. So it can be concluded that through guidance and counseling can be an effort to improve student self-efficacy.

AbstractHumans on earth need social interaction with others. Humans can use more than one language in communication. Thus, the impact that arises when the use of one or more languages is the contact between languages. One obvious form of contact between languages is interference. Interference can occur at all levels of life. As in this study, namely Indonesian Language Interference in Learning PPL Basic Thailand Unhasy Students. This study contains the form of interference that occurs in Thai students who are conducting teaching practices in the classroom. This type of research is descriptive qualitative research that seeks to describe any interference that occurs in the speech of Thai students when teaching practice. Data collection methods in this study are (1) observation techniques, (2) audio-visual recording techniques using CCTV and (3) recording techniques, by recording all data that has been obtained. Whereas the data wetness uses, (1) data triangulation, (2) improvement in perseverance and (3) peer review through discussion. Data analysis techniques in this study are (1) data collection, (2) data reduction, (3) data presentation and (4) conclusions. It can be seen that the interference that occurs includes (1) interference in phonological systems, (2) interference in morphological systems and (3) interference in syntactic systems.
