Social Security Programs Throughout the World: Asia and the Pacific, 2006

[Excerpt] This second issue in the current four-volume series of Social Security Programs Throughout the World reports on the countries of Asia and the Pacific. The combined findings of this series, which also includes volumes on Europe, Africa, and the Americas, are published at 6-month intervals over a 2-year period. Each volume highlights features of social security programs in the particular region. This guide serves as an overview of programs in all regions. A few political jurisdictions have been excluded because they have no social security system or have issued no information regarding their social security legislation. In the absence of recent information, national programs reported in previous volumes may also be excluded. In this volume on Asia and the Pacific, the data reported are based on laws and regulations in force in July 2006 or on the last date for which information has been received.1 Information for each country on types of social security programs, types of mandatory systems for retirement income, contribution rates, and demographic and other statistics related to social security is shown in Tables 1­4 at the end of the guide. The country summaries show each system's major features. Separate programs in the public sector and specialized funds for such groups as agricultural workers, collective farmers, or the self-employed have not been described in any detail. Benefit arrangements of private employers or individuals are not described in any detail, even though such arrangements may be mandatory in some countries or available as alternatives to statutory programs. The country summaries also do not refer to international social security agreements that may be in force between two or more countries. Those agreements may modify coverage, contributions, and benefit provisions of national laws summarized in the country write-ups. Since the summary format requires brevity, technical terms have been developed that are concise as well as comparable and are applied to all programs. The terminology may therefore differ from national concepts or usage.

IPO failures around the world

This thesis consists of two essays on IPO failures around the world. IPO failures are defined as IPO withdrawals (Essay 1) or delistings of recent IPOs for negative reasons (Essay 2). A common theme that runs through the two essays is the importance of institutional and cultural characteristics in explaining cross-country differences in IPO failures.

Managing parthenium weed across diverse landscapes: prospects and limitations

Parthenium is a weed of global significance affecting many countries in Asia, Africa, and the Pacific Islands. Parthenium causes severe human and animal health problems, agricultural losses as well as serious environmental problems. Management options for parthenium include chemical, physical, legislative, fire, mycoherbicides, agronomic practices, competitive displacement and classical biological control. The ability of parthenium to grow in a wide range of habitats, its persistent seed bank, and its allelopathic potential make its management difficult. No single management option would be adequate to manage parthenium across all habitats, and there is a need to integrate various management options (e.g. grazing management, competitive displacement, cultural practices) with classical biological control as a core management option.

Foods of pigeons and doves in fragmented landscapes of subtropical eastern Australia

We report dietary items of pigeons and doves from northern New South Wales and southern Queensland, obtained from opportunistic sampling of the gut contents of dead birds and observing foraging birds. Most records were from fragmented rainforest habitats, which now support abundant invasive fleshy-fruited plants. The fruits and seeds of invasive plants, particularly Camphor Laurel Cinnamomum camphora, formed the dominant food of several of the species sampled, although in some cases these birds appear to destroy most of the ingested seeds in the gizzard, thereby not contributing to weed dispersal. We also describe the first records of White-headed Pigeons Columba leucomela eating flowers and Brown Cuckoo-Doves Macropygia amboinensis eating flower buds. Camphor Laurel, via flowers, green and ripe fruits, and seeds, provided food for White-headed Pigeons in the Goolmangar district of New South Wales throughout the entire year. Seventy percent of the plant species whose fruits and seeds were recovered from the gut had not previously been recorded as food items for those bird species, illustrating how little is known about the diets of pigeons and doves in fragmented Australian landscapes.

Ryhmäidentiteetin mittaaminen verkkoroolipelissä World of Warcraft

The objective of the study was to explore the dimensions of group identity in the guilds of World of Warcraft. Previous research shows that social interaction has an important role in playing games for many players. Social identities are an important aspect of self-concept and since group related cues are more salient than personal clues in computer-mediated communication, the social gaming experience was approached through group identity. In the study a new scale will be developed to measure the group identity in games. Secondary goal is to study how different guild attributes affect the group identity and third goal is to explore the connection between group identity and gaming experience and amount of play. Subjects were 1203 guild members and 106 players not in a guild. The data was gathered by an Internet survey which measured group identity with nine scales, gaming experience with three scales and guild attributes with four scales. Also various background data was gathered. The construct of group identity was analyzed with explorative factor analysis. The typical experiences of group identity was analyzed with cluster analysis and effects of guild attributes with multivariate analysis of covariance. As a result of the study a new scale was developed which measured group identity on six dimensions: self-stereotyping, public and private evaluation, importance, interconnection of self and others and awareness of content. Group identity was experienced strongest in elder middle-sized guilds that had formal rules and that emphasized social interaction. The players with strong group identity had more positive gaming experience and played World of Warcraft more per week than the players who were not in a guild or identified to guild weakly. This result encourages game developers to produce environments that enhance group identity as it seems to increase the enjoyment in games. As a whole this study proposes that group identity in guilds is constructed from the same elements as in traditional groups. If this is truly the case, guild membership may have similar positive effects on individual’s mental well-being as traditional positively evaluated group memberships have.

Tiedonhakustrategiat World Wide Webissä

Tutkimuksen tarkoituksena on selvittää, millaisia tiedonhakustrategioita tiedonhakijatkäyttävät etsiessään tietoa Internetistä. Käyttäjät luokitellaan kolmeen ryhmään tiedonhakustrategiansa mukaan. Haku-suuntautuneet käyttäjät käyttävät enimmäkseen hakukoneita, niin koko Internetin kattavia kuin sivustojen sisäisiäkin. Linkkisuuntautuneet taas joko tietävät tai arvaavat kohdesivuston osoitteen tai käyttävät laajoja hierarkkisia hakemistoja tiedon löytämiseen. He navigoivat mielummin sivustollakin linkkejä käyttäen eivätkä yleensä käytä hakutoimintoa. Eriytyneet käyttäjät eivät säännönmukaisesti suosi kumpaakaan tapaa, vaan valitsevat strategian tehtävän mukaan. Tietoa kerättiin kahdella tavalla: WWW-sivulla olleella kyselylomakkeella ja tiedonhakutestillä, jossa käyttäjille annettiin suoritettavaksi erilaisia tiedonhakutehtäviä. Tiedonhakutehtävät lajiteltiin kolmeen ryhmään sen mukaan, mitä strategiaa ne suosivat: hakustrategiaa suosivat, linkkistrategiaa suosivat ja neutraalit tehtävät. Tutkimusongelmana oli selvittää, kuinka tehtävän tyyppi ja ATK- ja Internet-kokemus vaikuttavat tiedonhakustrategian valintaan. Kävi ilmi, ettei käyttäjien suuntautuneisuus tiettyyn strategiaan vaikuta tiedonhakustrategian valintaan, vaan ainoastaan tehtävän tyyppi oli merkitsevä tekijä. Aikaisemman tutkimustiedon valossa kokeenet suosivat haku-suuntautunutta strategiaa. Tässä tutkimuksessa havaittiin, että kokemus lisäsi molempien strategioiden käyttöä yhtäläisesti, mutta tämä ilmiö oli havaittavissa ainoastaan kysely-lomakkeen pohjalta, ei testeissä. Molempien tiedonhakustrategioiden käyttö lisääntyy kokemuksen myötä, mutta suhteelliset osuudet pysyvät samoina. Syyksi sille, että kokeneet eivät suosineet hakustrategiaa, esitetään sitä, että tehtävät olivat liian helppoja, jolloin kokemus ei pääse auttamaan. Oleellisia eroja suoritusajoissa tai hakustrategian vaihdon tiheydessä ei havaittu suhteessa kokemukseen, ainoastaan suhteessa tehtävän tyyppiin.Tämäkin selitettiin toisentyyppisten tehtävien helppoudella. Tutkimuksessa pohditaan lisäksi asiantuntijuuden syntyä tiedonhakukontekstissa sekä esitetään metatietohypoteesi, jonka mukaan tiedonhakustrategian valintaan vaikuttaa tärkeänä tekijänä käyttäjän metatieto hakupalveluista. Metatietoon kuuluu tieto siitä, mitä hakukoneita on saatavilla, mitä tietoa verkosta kannattaa hakea, millä yrityksillä ja yhteisöillä on sisältörikkaat sivut jne, ja minkä tyyppistä tietoa yleensä on saatavilla. Kaikenkaikkiaan strategian valintaan esitetään taustalle kolmen tason tiedon vaikutusta: 1) oma asiantuntemus haettavasta alasta, 2) metatieto Internetin tiedonhakupalveluista sekä 3) tekninen tieto siitä, kuinka hakukoneet toimivat.

Overcoming the challenges of building heritage projects: Improvements to time, scope and cost performance

This research was undertaken to encompass and identify challenges and impact factors that affect the successful outcomes of heritage building projects, especially those related to finding major causes of delays and cost overruns across projects in all Australian states. This project determined and analysed the causes of such delays and programme issues emanating from the planning and execution phases, whilst also analysing the requirements for management of multiple stakeholder relationships and the influence of unforeseen technical factors. The research proposes "call for action" guidance and was validated by experienced experts in heritage building projects in Australia. The proposed guidance is designed to ensure that realistic cost targets and delivery timeframes are set in future heritage projects, and necessary interventions made at appropriate project stages to ensure decisions are made that will help to prevent overtime and cost overuns.

Collation, analysis and research of thermal benefits of green life in the urban landscapes

This project reviewed international research conducted on the possible role of plants in alleviating high temperatures in our living spaces. The literature review served to identify the work that has already been carried out in the area and to highlight the gaps to be filled by experimental research. A pilot study then investigated the thermal properties of six of the most common landscaping materials. This project clearly shows that plants can play a significant role in modifying the thermal conditions of urban environments. Tall trees can shade nearby buildings and allow for reductions in cooling costs. In addition to basic shading, the dispersal of heat via the plant’s natural transpiration stream has long been recognised as an important component of the urban energy balance. It has been shown that urban temperatures can be up to 7°C higher than nearby rural areas, illustrating the impact of plants on their environment. These benefits argue against the idea of removing plants from landscapes in order to save on water in times of drought. Similarly, the idea of switching to artificial turf is questionable, since artificial turf still requires watering and can reach temperatures that far exceed the safe range for players. While vegetation offers evaporative cooling, non-vegetative, impervious surfaces such as concrete do not, and can therefore cause greater surface and soil temperatures. In addition, the higher temperatures associated with these impervious surfaces can negatively affect the growth of plants in surrounding areas. Permeable surfaces, such as mulches, have better insulating properties and can prevent excessive heating of the soil. However, they can also lead to an increase in reflected longwave radiation, causing the leaves of plants to close their water-conducting pores and reducing the beneficial cooling effects of transpiration. The results show that the energy balance of our surroundings is complicated and that all components of a landscape will have an impact on thermal conditions.

Specific detection of the Old World screwworm fly, Chrysomya bezziana, in bulk fly trap catches using real-time PCR.

The Old World screwworm fly (OWS), Chrysomya bezziana Villeneuve (Diptera: Calliphoridae), is a myiasis-causing blowfly of major concern for both animals and humans. Surveillance traps are used in several countries for early detection of incursions and to monitor control strategies. Examination of surveillance trap catches is time-consuming and is complicated by the presence of morphologically similar flies that are difficult to differentiate from Ch. bezziana, especially when the condition of specimens is poor. A molecular-based method to confirm or refute the presence of Ch. bezziana in trap catches would greatly simplify monitoring programmes. A species-specific real-time polymerase chain reaction (PCR) assay was designed to target the ribosomal DNA internal transcribed spacer 1 (rDNA ITS1) of Ch. bezziana. The assay uses both species-specific primers and an OWS-specific Taqman MGB probe. Specificity was confirmed against morphologically similar and related Chrysomya and Cochliomyia species. An optimal extraction protocol was developed to process trap catches of up to 1000 flies and the assay is sensitive enough to detect one Ch. bezziana in a sample of 1000 non-target species. Blind testing of 29 trap catches from Australia and Malaysia detected Ch. bezziana with 100% accuracy. The probability of detecting OWS in a trap catch of 50 000 flies when the OWS population prevalence is low (one in 1000 flies) is 63.6% for one extraction. For three extractions (3000 flies), the probability of detection increases to 95.5%. The real-time PCR assay, used in conjunction with morphology, will greatly increase screening capabilities in surveillance areas where OWS prevalence is low.
