Abstract Cowpea mild mottle virus (CPMMV) infects a wide range of cultivated legumes. It causes severe mosaic and/or necrosis on the leaves, stems and pods of beans (Phaselous), cowpea (Vigna) and soyabean (Glycine max). Yield losses of 64-80% have been recorded in groundnuts in Kenya (Bock et al., 1976, 1977) and 10-100% in soyabean in Brazil and Argentina (Brown and Rodrigues, 2017). The virus is transmitted in a non-persistent manner by the whitefly, Bemisia tabaci. CPMMV is considered endemic to Africa, but has spread to India, South-East Asia, South America, the Caribbean, Puerto Rico and Mexico. Introduction of the virus to Puerto Rico, and possibly also Mexico, is thought to have been through infected seed from South America and perhaps Africa. The virus poses a threat to soyabean production in the USA and, if introduced into mainland USA, CPMMV has potential to spread through seed, on infected ornamental or vegetable transplants, and by the viruliferous whitefly, itself if previously associated with a virus-infected host.

Abstract Leptochloa mucronata is a grass native to the warmer parts of North, Central and South America and the Caribbean; taxonomists disagree over whether the form found in the Caribbean is part of the same species or should be classified separately as Leptochloa panicea ssp. brachiata. The species is present in a number of countries in south and south-east Asia, in a few countries in Africa, and in Australia; in most of these countries it is considered to be introduced, although it is reported as native in some of them. Little information is available about how it was spread, but it probably involved the accidental movement of seeds. In parts of both its native range and its introduced range it is a significant agricultural weed, and this is the main reason why it is of interest, although there have been some studies of its use as a green manure.

Writing from a wide range of historical perspectives, contributors to the anthology shed new light on historical, theoretical and empirical issues pertaining to the documentary film, in order to better comprehend the significant transformations of the form in colonial, late colonial and immediate post-colonial and postcolonial times in South and South-East Asia. In doing so, this anthology addresses an important gap in the global understanding of documentary discourses, practices, uses and styles. Based upon in-depth essays written by international authorities in the field and cutting-edge doctoral projects, this anthology is the first to encompass different periods, national contexts, subject matter and style in order to address important and also relatively little-known issues in colonial documentary film in the South and South-East Asian regions. This anthology is divided into three main thematic sections, each of which crosses national or geographical boundaries. The first section addresses issues of colonialism, late colonialism and independence. The second section looks at the use of the documentary film by missionaries and Christian evangelists, whilst the third explores the relation between documentary film, nationalism and representation.

Abstract C. rutidosperma is a common herb that grows as a weed in disturbed and ruderal habitats, principally in areas with humid and hot environmental conditions. It is often found as a weed of disturbed ground, roadsides, gardens, crops and abandoned lands, and has also been found growing as an epiphyte on trees, stone walls and cliff faces. This species is included in the Global Compendium of Weeds (Randall, 2012) where it is considered to have moderate economic impacts in a wide range of crops, due to its scrambling habit that smothers and stunts young crop plants. C. rutidosperma has been listed as invasive in China, Malaysia, India, Thailand, Vietnam, Australia, and the Domican Republic (Waterhouse and Mitchell, 1998; Kairo et al., 2003; Flora of China Editorial Committee, 2014, USDA-ARS, 2014). This species has had considerable environmental impacts in South East Asia and Australia. C. rutidosperma also has the potential to be moderately problematic in intensive cropping areas, greenhouses and nurseries.

This article aims at adressing several research issues. Firstly, to present offensive realism as a proper research tool to analyse US-China rivalry. Secondly, the author discusses the theory of “China’s peaceful rise” and I argues that it smoothly overlapped with the US strategy of liberal hegemony. Thirdly, He presents and defends the argument that China does not rise peacefully. Fourthly, the author claims that China wants to became a regional hegemon in South-East Asia and the USA according to offensive realism cannot let it happen. Last but not least the author considers the arguments that are frequently used to support the theory of “China’s peaceful rise” and explains why they fail to depict the current and predict the future nature of US-China relations. In this article the author employed the following research methods: historical, descriptive and decision making methods.

From the beginning of the Bagan period (11th century CE), Buddha’s Parinirvāṇa Scene has been depicted on wall paintings in religious buildings and hollow vaulted temples at various places of middle Myanmar. It is found that wall paintings based on the Maha Parinirvāṇa Sutta vary in layout and size from period to period with Buddhist literature: just as single-scenes and small or large wall paintings were depicted during the Bagan period so also were depictions of multiple scenes made in the late Konbaung Period. Further additions were introduced in depictions of Buddha’s Parinirvāṇa in the late Bagan Period. When studying the Buddha’s Parinirvāṇa scene on wall paintings, the depicting styles and colour changed from period to period. Depending on the colour, the periods can be interpreted definitely. Wall paintings depicting the Parinirvāṇa Sutta at temples located in Bagan and middle Myanmar regions are compared among themselves to show differences and similarities. Accounts of the purported events surrounding the Buddha's own Parinirvāṇa are found in a wide range of Buddhist countries of South East Asia. This paper concludes that the hypothesis is viable, with comparisons with the wall paintings depicting Buddha’s Parinirvāṇa Scene in Myanmar and how the style changed and transformed.မြန်ြာနှိိုင်ငံအလယ်ပှိိုင်ေးဆနရာအနှံှံ့အမပာေးတွင် ပိုဂံဆခတ်အဆစာပှိိုင်ေးကာလ(၁၁ရာစို)ြှစ၍ ဗိုဒ္ဓ၏ပရှိနှိဗဗာန်စံခန်ေးကှိို ဘာသာ ဆရေး ှိိုင်ရာ အဆ ာက်အဦေးအြ ှိြုေးြ ှိြုေးနှငဲ့် ဂူဘိုရာေးဝတ်မပြုဆက ာင်ေးြ ာေး၏နံရံြ ာေးတွင် သရိုပ်ဆ ာ်ဆရေး ွွဲခွဲဲ့ကကသည်။ ြဟာပရှိ နှိဗဗာနသိုတတံကှိို အဆမခခံဆသာ နံရံဆ ေးဆရေးပန်ေးခ ျီြ ာေး၏ အခင်ေးအက င်ေး၊ အရွယ်အစာေးြ ာေးသည် ဆခတ်ကာလအလှိိုက် ကွွဲမပာေး မခာေးန ေးြှိုရှှိပပျီေး ပိုဂံဆခတ်ကာလက ဇာတ်ကွက်တစ်ကွက်ကှိိုသာ အရွယ်အစာေးအာေးမ ငဲ့် ကကျီေးသည်မ စ်ဆစ၊ ငယ်သည်မ စ်ဆစ နံရံဆ ေးဆရေးပန်ေးခ ျီတွင် သရိုပ်ဆ ာ်ဆရေး ွွဲဆလဲ့ရှှိပပျီေး ကိုန်ေးဆဘာင်ဆခတ်ဆနှ င်ေးပှိိုင်ေးကာလတွင် ဇာတ်ကွက်တစ်ကွက်ထက် ပှိိုြှိို ဆရေး ွွဲလာသည်ကှိို ဆတွွေ့ရှှိရပါသည်။ ဗိုဒ္ဓ၏ပရှိနှိဗဗာန်မပြုပံိုဇာတ်ကွက်အာေး သရိုပ်ဆ ာ်ဆရေး ွွဲရာတွင် ပိုဂံဆခတ်ဆနှ င်ေးပှိိုင်ေးကာ လ၌ ထပ်ြံထညဲ့်သွင်ေးြှိုြ ာေးကှိို မပြုလိုပ်လာကကသည်။ နံရံဆ ေးဆရေးပန်ေးခ ျီြှ ဗိုဒ္ဓ၏ပရှိနှိဗဗာန်ဇာတ်ကွက်အာေးဆလဲ့လာသညဲ့်အခါ သရိုပ်ဆ ာ်ဆရေး ွွဲြှိုပံိုစံြ ာေးနှငဲ့် ဆ ေးဆရာင်မခယ်သြှိုြ ာေးြှာ ဆခတ်ကာလအလှိိုက် ဆမပာင်ေးလွဲလာကကသည်။ ဆ ေးဆရာင်မခယ်သ ြှိုအဆပေါ်ြူတည်၍ ဆခတ်ကာလကှိို အတှိအက ဆ ာ်မပနှိိုင်သည်။ ပိုဂံနှငဲ့်မြန်ြာနှိိုင်ငံအလယ်ပှိိုင်ေးြှ ဘာသာဆရေးအဆ ာက်အဦေး ြ ာေးနှငဲ့် ဂူဘိုရာေးဝတ်မပြုဆက ာင်ေးြ ာေးတွင်ရှှိဆသာ နံရံဆ ေးဆရေးပန်ေးခ ျီြ ာေး၌ ပရှိနှိဗဗာနသိုတတံအာေး သရိုပ်ဆ ာ်ဆရေး ွွဲပံိုြ ာေးအကကာေး ကွွဲမပာေးမခာေးန ေးြှို၊ တူညျီြှိုတှိိုှံ့အာေး မပသနှိိုင်ရန်နှိှိုင်ေးယှဉ်ဆလဲ့လာထာေးပါသည်။ အဆရှွေ့ဆတာင်အာရှြှ ဗိုဒ္ဓဘာသာဝင်နှိိုင်ငံြ ာေးအ ကကာေး ဗိုဒ္ဓ၏ပရှိနှိဗဗာန်စံခန်ေးနှငဲ့်စပ်လ ဉ်ေးသညဲ့်ဆ ာ်မပခ က်ြ ာေးကှိို က ယ်မပနှံ့်စွာဆတွွေ့ရှှိရဆပသည်။ ယခိုစာတြ်ေးသည် အဆရှွေ့ ဆတာင်အာရှနှိိုင်ငံြ ာေးြှ နံရံဆ ေးဆရေးပန်ေးခ ျီြ ာေးတွင် သရိုပ်ဆ ာ်ဆရေး ွွဲထာေးဆသာ ပရှိနှိဗဗာန်စံခန်ေးနှငဲ့်ထှိိုင်ေးနှိိုင်ငံတှိိုှံ့ြှသရိုပ်ဆ ာ် ပံိုြ ာေးကှိို နှိှိုင်ေးယှဉ်ဆလဲ့လာြှိုြ ာေး မပြုလိုပ်နှိိုင်သည်ဟူဆသာ အယူအ ကှိို ဆကာက်ခ က်ခ ထာေးပါသည်။
