A Comparative-Correlational Study Of Attitudes Toward And Motivation For Learning English As A Foreign Language In Grade 9 Students From Akha, Bamar And Shan Ethnic Groups At № 2 Basic Education High School, Keng Tung, Eastern Shan State, Myanmar

The purpose of this study was to determine whether there was a significant relationship between attitudes and motivation of Grade 9 students toward English as a foreign language from the Akha, Bamar, and Shan ethnic groups and to compare both variables among three different ethnic groups at № 2 Basic Education High School, Keng Tung, Eastern Shan State, Myanmar. A total of 199 students participated, and the instrument adapted for this study was the latest version of Gardner’s (2004) Attitude/Motivation Test Battery. Pearson product-moment correlation coefficient was used to examine the relationship between the research variables, and a one-way analysis of variance (ANOVA) was performed to determine if there were significant differences between attitudes and motivation of the participant students. From this study, a positive attitude and high motivation of Grade 9 students toward learning English as a foreign language (EFL) were found, regardless of their ethnic memberships. Also, it was found a statistically strong, positive correlation between attitudes toward and motivation for learning EFL of Grade 9 students in each ethnic group. Furthermore, the findings also revealed a significant difference between attitudes toward EFL of the students, but no significant difference between motivations for learning EFL of the students in all three ethnic groups. Finally, recommendations for teachers, students, administrators and future researchers are presented

Human–elephant coexistence challenges in Myanmar: An analysis of fatal elephant attacks on humans and elephant mortality

Understanding the underlying causes behind human–elephant conflict (HEC)-driven mortality of humans and elephants will help improve both parties’ wellbeing. The objective of this study was to examine the temporal and spatial mortality patterns of humans and elephants and the influence of local attitudes, conflict factors and habitat factors on elephant poaching. We used the Myanmar Forest Department data from 2001 to 2020 for humans and 2011 to 2020 for elephants together with explanatory data on human attitudes, habitat, and conflict factors. Approximately seven persons were killed annually in elephant attacks, with a bias towards men. The annual mortality of elephants during the study period was on average 16 individuals, and most elephants were killed by humans. There was a significant relationship between the number of killed humans and human-killed elephants around HEC villages. Villages with more property damage exhibited a higher rate of human mortality, which also correlated with negative feelings of local people towards elephants. Elephant poaching was higher in villages with less suitable habitat available for elephant use. Human encroachment is an important cause of HEC, leading to human loss and forming the main threat to the survival of wild elephants. We suggest local involvement to ensure good governance in conflict resolution and mitigation strategies and to strengthen law enforcement.

Effect of human–elephant conflict on local attitudes toward the conservation of wild Asian elephants in Myanmar

The study of attitudes toward wild elephants and human–elephant conflict (HEC) is vital to understanding what attitudes are held by local people and how to incorporate them into wild elephant conservation. This study investigated the interlinkages between the HEC experience and local people’s attitudes toward the conservation of wild elephants and which exploratory factors influence these attitudes. We used a Bayesian Belief Network (BBN) framework to highlight the interlinkages between HEC and people’s attitudes. The basic BBN model indicated that HEC was central in determining the attitudes of local people. Although people generally hold positive attitudes toward elephants, people support having elephants in the country but not in their own regions. Conservation willingness was not obvious due to the lack of deliberate assistance from the government to the affected communities. We suggest implementing education programs to promote local awareness of conflict mitigation techniques.

Bacteria isolated from Bengal cat (Felis catus × Prionailurus bengalensis) anal sac secretions produce volatile compounds potentially associated with animal signaling.

In social animals, scent secretions and marking behaviors play critical roles in communication, including intraspecific signals, such as identifying individuals and group membership, as well as interspecific signaling. Anal sacs are an important odor producing organ found across the carnivorans (species in the mammalian Order Carnivora). Secretions from the anal sac may be used as chemical signals by animals for behaviors ranging from defense to species recognition to signaling reproductive status. In addition, a recent study suggests that domestic cats utilize short-chain free fatty acids in anal sac secretions for individual recognition. The fermentation hypothesis is the idea that symbiotic microorganisms living in association with animals contribute to odor profiles used in chemical communication and that variation in these chemical signals reflects variation in the microbial community. Here we examine the fermentation hypothesis by characterizing volatile organic compounds (VOC) and bacteria isolated from anal sac secretions collected from a male Bengal cat (Felis catus × Prionailurus bengalensis), a cross between the domestic cat and the leopard cat. Both left and right anal sacs of a male Bengal cat were manually expressed (emptied) and collected. Half of the material was used to culture bacteria or to extract bacterial DNA and the other half was used for VOC analysis. DNA was extracted from the anal sac secretions and used for a 16S rRNA gene PCR amplification and sequencing based characterization of the microbial community. Additionally, some of the material was plated out in order to isolate bacterial colonies. Three taxa (Bacteroides fragilis, Tessaracoccus, and Finegoldia magna) were relatively abundant in the 16S rRNA gene sequence data and also isolated by culturing. Using Solid Phase Microextraction (SPME) gas chromatography-mass spectrometry (GC-MS), we tentatively identified 52 compounds from the Bengal cat anal sac secretions and 67 compounds from cultures of the three bacterial isolates chosen for further analysis. Among 67 compounds tentatively identified from bacterial isolates, 51 were also found in the anal sac secretion. We show that the bacterial community in the anal sac consists primarily of only a few abundant taxa and that isolates of these taxa produce numerous volatiles that are found in the combined anal sac volatile profile. Several of these volatiles are found in anal sac secretions from other carnivorans, and are also associated with known bacterial biosynthesis pathways. This is consistent with the fermentation hypothesis and the possibility that the anal sac is maintained at least in part to house bacteria that produce volatiles for the host

Asymptomatic and sub-microscopic malaria infection in Kayah State, eastern Myanmar

Myanmar has the heaviest burden of malaria in the Greater Mekong Sub-region. Asymptomatic Plasmodium spp. infections are common in this region and may represent an important reservoir of transmission that must be targeted for malaria elimination.; A mass blood survey was conducted among 485 individuals from six villages in Kayah State, an area of endemic but low transmission malaria in eastern Myanmar. Malaria infection was screened by rapid diagnostic test (RDT), light microscopy and real-time polymerase chain reaction (PCR), and its association with demographic factors was explored.; The prevalence of asymptomatic Plasmodium spp. infection was 2.3% (11/485) by real-time PCR. Plasmodium vivax accounted for 72.7% (8/11) and Plasmodium falciparum for 27.3% (3/11) of infections. Men were at greater risk of infection by Plasmodium spp. than women. Individuals who worked as farmers or wood and bamboo cutters had an increased risk of infection.; A combination of RDT, light microscopy and PCR diagnostics were used to identify asymptomatic malaria infection, providing additional information on asymptomatic cases in addition to the routine statistics on symptomatic cases, so as to determine the true burden of disease in the area. Such information and risk factors can improve malaria risk stratification and guide decision-makers towards better design and delivery of targeted interventions in small villages, representative of Kayah State

Molecular evidence of drug resistance in asymptomatic malaria Infections, Myanmar, 2015

Artennisinin resistance containment in Myanmar was initiated in 2011 after artemisinin-resistant Plasmodium falciparum malaria was reported. Molecular evidence suggests that asymptomatic malaria infections harboring drug resistance genes are present among residents of the Myanmar artemisinin resistance containment zone. This evidence supports efforts to eliminate these hidden infections.Publisher PDFPeer reviewe

Effective high-throughput blood pooling strategy before DNA extraction for detection of malaria in low-transmission settings

In the era of (pre) elimination setting, the prevalence of malaria has been decreasing in most of the previously endemic areas. Therefore, effective cost-and time-saving validated pooling strategy is needed for detection of malaria in low transmission settings. In this study, optimal pooling numbers and lowest detection limit were assessed using known density samples prepared systematically, followed by genomic DNA extraction and nested PCR. Pooling strategy that composed of 10 samples in 1 pool, 20 μl in 1 sample, was optimal, and the parasite density as low as 2 p/μl for both falciparum and vivax infection was enough for detection of malaria. This pooling method showed effectiveness for handling of a huge number of samples in low transmission settings.Publisher PDFPeer reviewe

Co-occurrence of Point Mutations in the Voltage-Gated Sodium Channel of Pyrethroid-Resistant Aedes aegypti Populations in Myanmar

Background:Single amino acid substitutions in the voltage-gated sodium channel associated with pyrethroid resistance constitute one of the main causative factors of knockdown resistance in insects. The kdr gene has been observed in several mosquito species; however, point mutations in the para gene of Aedes aegypti populations in Myanmar have not been fully characterized. The aim of the present study was to determine the types and frequencies of mutations in the para gene of Aedes aegypti collected from used tires in Yangon City, Myanmar.Methodology/Principal Findings:We determined high pyrethroid resistance in Aedes aegypti larvae at all collection sites in Yangon City, by using a simplified knockdown bioassay. We showed that V1016G and S989P mutations were widely distributed, with high frequencies (84.4% and 78.8%, respectively). By contrast, we were unable to detect I1011M (or I1011V) or L1014F mutations. F1534C mutations were also widely distributed, but with a lower frequency than the V1016G mutation (21.2%). High percentage of co-occurrence of the homozygous V1016G/S989P mutations was detected (65.7%). Additionally, co-occurrence of homozygous V1016G/F1534C mutations (2.9%) and homozygous V1016G/F1534C/S989P mutations (0.98%) were detected in the present study.Conclusions/Significance:Pyrethroid insecticides were first used for malaria control in 1992, and have since been constantly used in Myanmar. This intensive use may explain the strong selection pressure toward Aedes aegypti, because this mosquito is generally a domestic and endophagic species with a preference for indoor breeding. Extensive use of DDT for malaria control before the use of this chemical was banned may also explain the development of pyrethroid resistance in Aedes aegypti

Costs and benefits associated with natural resource exploitation in Chatthin Wildlife Sanctuary in Myanmar, and its impact on thamin (Rucervus eldii thamin) conservation

The conservation of wildlife in the Anthropocene inevitably depends on an understanding of how human populations interact with wildlife and its habitat. This involves understanding (1) how they exploit the natural resources of a given area, (2) any conflicts they have with wildlife, and (3) their attitudes towards wildlife and its conservation. This study aimed to examine the costs and benefits that local people experienced from living near a protected area (PA) that has been established in central Myanmar to protect one of the last populations of an endangered thamin (Rucervus eldii thamin), and consequently gain insights into how they viewed and responded to their conservation. A questionnaire survey was conducted in nine villages with 209 respondents. The results showed that the people living inside the PA exploited many of the area s natural resources, but also they at the same time suffered many costs associated with conflicts caused by the wildlife in PA. Despite this, they still held positive attitudes towards both thamin and the PA. Thamin was identified as the most common crop raider among the medium-sized wildlife. Communities living inside the PA had better knowledge about PA s operations and to some extent supported the thamin conservation, than those from communities along the edge of the PA or outside, however the enclaved communities stated that they were less likely to report thamin poaching to the authorities. Illegal thamin hunting is apparently still going on in the area and the local people living within the PA were more aware about the recent thamin population decline than those from the edge or external villages
