Abstract Ipomoea nil is a climber species that has been widely cultivated as a garden ornamental across tropical, subtropical and warm temperate regions of the world. It is an aggressive and opportunistic colonizer producing stems that either twine into other plants for support or sprawl along the ground. It has escaped from cultivation and become widely naturalized and invasive, primarily in areas near cultivation, disturbed areas and forest edges. Currently, I. nil is listed as invasive in China, India, Philippines, Spain, Galapagos, Cuba, and on several islands in the Pacific Region.

Abstract Ipomoea indica is a vine that has been widely cultivated as a garden ornamental across tropical, subtropical and warm temperate regions of the world (Randall, 2017; USDA-ARS, 2017). It is an aggressive and opportunistic colonizer of open and disturbed habitats that has escaped from cultivation to become widely naturalized in disturbed areas near gardens, coastal areas, forest edges, and along roadsides and waterways. This species spreads by seeds, stolons, and stem fragments and when growing under favourable environmental conditions (e.g., full sun, ample moisture and fertile soil) it can spread very rapidly, smothering all other vegetation growing nearby. Its rapidly growing stolons can form dense mats over the ground, while its climbing habit enables it to compete successfully with trees and shrubs on the edges of forests and along riparian zones. Its twining stems also choke adjacent seedlings and smother young trees and shrubs in the understory (Wagner et al., 1999; Csurches, 2016). Currently, I. indica is listed as invasive in Australia, New Zealand, China, southern Africa, Europe, the West Indies, and on many islands in the Pacific Region (Smith, 2010 BioNET-EAFRINET, 2017; DAISIE, 2017; Flora of China Editorial Committee, 2017; GRIIS, 2017; PIER, 2017; Queensland Government, 2017).

Abstract Ipomoea hederifolia is an annual climbing vine species, native to the tropical and warm temperate parts of the Americas, which has been introduced to many parts of the world as an ornamental plant. It has escaped from cultivation to become naturalized and invasive mostly in disturbed sites and riparian areas (PIER, 2016; Queensland Government, 2016). It also behaves as a weed in cultivated fields (such as sugarcane and soybean fields) in areas within and outside its native distribution range (Kissmann and Groth, 1999; Randall, 2012; USDA-ARS, 2016). It has the potential to outcompete other plant species for nutrients, water and sunlight. Currently it is listed as a serious agricultural weed in Brazil (Kissmann and Groth, 1999; Silva et al., 2009; Calore et al., 2014) and as an invasive species in Cuba, Australia, Hawaii, Fiji, New Caledonia and other islands in the Pacific region (Wagner et al., 1999; Oviedo et al., 2012; PIER, 2016; Queensland Government, 2016).

The Indo-Pacific region is an area adjacent to some oceans and the gateway that connects the great power and small countries to the world; this region is always considered by Vietnam as a key strategic geographic area, having direct impacts on national security, position and its role in this region. While big powers have different perceptions to the Indo-Pacific region, as a country occupying an important geographic position in the Pacific region, Vietnam shares a common vision of an open and rule-based area, and a common interest in maintaining peace, stability and prosperity as well as building a common space for coexistence and development with the belief that the Indo-Asian-Pacific is large enough for every nation to grow and prosper. This article finds out that recent changes in the Indo-Pacific region in geopolitics, economics, security and national defence have made many countries, including Vietnam, to redefine their global and regional policies to refresh their strategic perceptions. Vietnam has its own perception, position, approach and national orientations, which is shaping its state behaviour and perspectives in this geopolitical vibrant Indo-Pacific region. Besides, this article uses the SWOT analysis model to determine the challenges, strengths and weaknesses of Vietnam in the Indo-Pacific region. Moreover, while the future of the Indo-Pacific in a post-COVID-19 pandemic world remains filled with uncertainty and economic challenges, the crisis also presents an opportunity for Vietnam to re-evaluate its position. Today, Vietnam always maintains its foreign policy of independence, self-reliance, multilateralism and diversification of international relations, which attaches great importance to enhancing multi-faceted cooperation with countries in the Indo-Pacific region. Thus, with its own perception and geostrategic advantage, Vietnam—a developing country in the region and in the world with relatively stable economic growth, pursuing rules and order will be a positive factor for a stable, peaceful and prosperous development in the region.

AbstractThe Pacific region is one of the most culturally diverse areas of the world; societies within this region are also culturally diverse. For both these reasons, intercultural relations and acculturation phenomena are at the forefront of psychological interests there. This paper first situates these phenomena in their ecological and cultural contexts, in which human diversity and individual behaviour can be examined and understood as adaptations to these contexts. Then the notion of differentiation in psychological and sociocultural phenomena is discussed, linking them to the concept of social capital. The processes involved in acculturation and intercultural relations are then described, and linked to the concept of differentiation. The argument is presented (with an empirical example from research with immigrant youth) that the more differentiated are a person's psychological life, as well as their social and cultural engagements, then the better adapted they are to living interculturally. Suggestions for policy and programme development and implementation are made: these include advancing the multicultural way of living together, and of accepting the need for mutual accommodation.

The COVID-19 pandemic has become a challenge for the global community and has led to a sharp downturn in the economies of many countries around the world. In January 2020, the IMF said that the world is heading towards a new Great Depression, as there is a trend similar to the situation of the 1920s. Hence, according to forecasts, the rate of economic growth in East Asia and the Pacific region by the end of 2020 will decrease to 0.5% and will reach the lowest level since 1967, being a reflection of the shocks associated with the pandemic. In China, extremely restrictive measures have led to an almost complete halt in business activity in some sectors and regions. China’s economic growth is expected to slow to 1% in 2020. Economic activity in the rest of East Asia and the Pacific region is projected to decline by 1.2% in 2020 and will recover to 5.4% in 2021. The economic consequences of the COVID-19 pandemic have had a detrimental impact on the countries of Europe and Central Asia, with the overall recession to 4.7% as forecasted for 2020. In the Middle East and North Africa, a 4.2% decline in economic activity is forecasted, because of the development of the pandemic and the collapsed oil market. In South Asia, as a result of measures to mitigate the effects of pandemics and collapse of global demand, have sharply fallen the volumes of industry, services and trade activities. The effects of the pandemic and the drastic fall in global commodity prices was a crushing blow for Latin American and Caribbean countries. A sharp slowdown in the economies of U.S. and China has disrupted supply chains to Mexico and Brazil and caused a stark drop in exports from Chile and Peru. The downturn in tourism has also had negative consequences. Such statistics confirm the opinion of many leading scholars in the world that the result of the COVID-19 pandemic will be a decrease in the level of hyperglobization of the world economy. In addition, a move away from U.S.-oriented globalization and a shift toward China-oriented globalization will also be likely.

With the marginalization of Africa in international trade, previous models for operationalizing relations with Europe have become obsolete. There is increasingly a trend towards uncoupling between North Africa, the Republic of South Africa, and Black Africa. North Africa has broken away to the point of regarding itself as a hinterland of Europe. South Africa is likely to become both a crossroads and a transit point in trade between Europe, Africa, and the Pacific region. In Black Africa, the only current scenarios for reconnection with the rest of the world seem to amount to pointing out this subregion's capability to do harm if it were ever abandoned.

<p>While exploring different topics and issues—examining everything from the importance of our Pacific genealogies, to the analysis of Hawaiian language literature, to the power of prophecies and predictions for the future, to the need to be reflexive in the creation of culture, and finally to the act of building a nation—each chapter of this thesis is connected by one shifting concept: Kahiki. Furthermore, they are joined by the idea that there is life to be found there. As an ʻōlelo noʻeau, or a Hawaiian proverb, states, “Aia ke ola i Kahiki,” “Life is in Kahiki”. This adage has served as the foundation of this research and each chapter has been written with the belief that there is life—in the form of reconstructed knowledge, new interpretations, and growing understandings—to be found in Kahiki.  Encapsulated in this one term are our ancestral memories of migration. When islanders traveled to different parts of the Pacific region, they maintained knowledge of their homelands. Although the names of these homelands differ throughout the Pacific, the concept is the same: islanders knew that their life in a particular place, a particular group of islands, was dependent on other places and peoples that although out of sight were never completely out of memory. After generations, however, the specificity of these “homelands” was blurred, and one name came to represent the genealogical connection that people shared with other places in the Pacific. What was Pulotu for some, therefore, became Hawaiki for others, and eventually became Kahiki for my ancestors in Hawaiʻi. Thus, Kahiki became a general term for all lands in the region outside of Hawaiʻi, and more importantly, became a way for Hawaiians to explain their existence to themselves. In later generations, however, particularly when people from other parts of the world came to Hawaiʻi, Kahiki became a term used to refer to all lands beyond Hawaiʻi’s shores.  This thesis, therefore, studies the life of this one concept through time: looking at it as part of our Pacific genealogies, as presented in oral traditions; examining it as a means of making nationalistic statements, and sometimes, even as a means of justifying colonialism in the nineteenth century; and then exploring contemporary articulations and engagements with Kahiki, particularly in the era following the Hawaiian renaissance, when a group of men on the Big Island of Hawaiʻi built a single-hulled canoe, brining tools, teachers, and knowledge from Kahiki to give new “life” to their people. Studying the way this one concept has shifted through time provides a means of understanding how people in each generation used one term to make sense of their experiences. Furthermore, it gives us the chance to examine our contemporary movements and to reengage with Kahiki in a way that will empower us to do and be more for our people, our region, and the world.</p>

Abstract A. spinosus is a serious weed in tropical and subtropical regions of the world. For instance, it is a troublesome weed in agricultural areas, pastures, and orchards in Africa, Asia, Europe, Australia, and the Pacific region. In those regions, it is also a serious environmental weed in disturbed sites, secondary forests, along forest edges, and around water troughs (Lemmens and Bunyapraphatsara, 1999; Motooka et al., 2003; PIER, 2015; PROTA, 2015; USDA-ARS, 2015). The plant has large thorns which make it unpalatable for grazing livestock and make weeding difficult in parts of the world where hand weeding and harvest are done by hand. Like other amaranths, it produces large numbers of seeds, which can mature after the plant has been cut, and remain viable for long periods.

This paper explores eco-theological responses to climate change in Oceania. First, we review central texts in the contextual theological tradition in Oceania, focusing on recent responses to climate change. This points to a body of theological texts integrating climate change into a broader effort to reform classical theologies and church practices. Secondly, we identify challenges facing the contextual theologies, among them recent claims about climate-change-denying responses by Biblicist Christians in the Pacific region. These challenges apart, we suggest, thirdly, that the churches are important actors in the cultural modeling of climate change. We highlight the uniqueness of Christian narratives from the Pacific region, while alluding to the fact that literal interpretations of scriptures are influential in many other parts of the world too.
