Impact of exchange rate changes on domestic inflation: a study of a small Pacific Island economy

This paper investigates the effect of changes in exchange rate on consumer price level, in Fiji, known as exchange rate pass-through during a thirty year period (1982-2009). Specifically, three time periods are focused on: the pre-coup years (1982-1986); post coup years (1987-2009); and full time period (1982-2009). Monthly data on consumer price index, nominal exchange rate, monetary aggregate and interest rate are utilized. The study results show that the degree of exchange rate pass-through to domestic price was relatively low during the entire sample period at 0.183. It was 0.453 and 0.373 for the pre and post coups periods. Regardless of the sample periods under study, the monetary aggregate, as a variable plays a pivotal in stabilizing the price level.Exchange rate pass-through, price, monetary measure, cointegration, Granger causality

Impact of global growth fluctuations on India: an empirical study

The article examines how growth fluctuations in major trading partner countries of the world have affected the Indian economy since its liberalization from the mid 1990s. This empirical study confirms that domestic output of India was strongly influenced by global shocks. The findings are not surprising as India’s trade and financial integration with the rest of the world has been on the rise.Economic integration, global shock, regional shock, India

Task Complexity and Linguistic Complexity: An Exploratory Study

Central to any task-based syllabus is the notion of complexity. Proponents of task-based language teaching (TBLT) have argued that tasks be sequenced according to their inherent cognitive complexity, partially because learner performance changes according to the complexity of the task. This exploratory study examines the effect of task complexity on the linguistic complexity of task performance. The participants in the study were a group of ten advanced- level second language (L2) English speakers, and two groups of native speakers of English. Task complexity was operationalized by manipulating two independent variables – reasoning demand and contextual support – in a series of picture narration tasks. The study thus had a 2 x 2 factorial design, with participants completing the tasks under four different sets of conditions. Each set provided the participants with different reasoning demands and/or contextual support. Repeated measures ANOVA were used to analyze the initial data. Following these analyses, separate ANOVAs were calculated to distinguish between the types of reasoning that may have contributed to differences in task performance. It was found that contextual support had little influence on the complexity of task performance, but that reasoning demands, specifically causal and spatial reasoning, may have contributed to differences in the linguistic complexity of participants‟ task performance

Role of Remittances in Economic Development: An Empirical Study of World’s Two Most Remittances Dependent Pacific Island Economies

In the context of the ongoing world-wide recession and the consequent dim prospects for exports from small Pacific island countries, mobilization of foreign exchange earnings assumes considerable importance. The dependency of Samoa and Tonga on inward remittances is well known, as the two Polynesian island countries in recent years have been amongst the first top ten remittance recipient countries of the world. This paper examines the long-run nexus between economic growth and inward remittances during a three-decade period (1981-2008). The paper also discusses some important policy implications arising out of the study findings.Remittances, financial sector development, economic growth, bounds test, Samoa, Tonga

Navigating cancer using online communities: a grounded theory of survivor and family experiences

Purpose: People affected by cancer often have unmet emotional and social support needs. Online cancer communities are a convenient channel for connecting cancer survivors, allowing them to support one another. However, it is unclear whether online community use makes a meaningful contribution to cancer survivorship, as little previous research has examined the experience of using contemporary cancer communities. We aimed to explore the experiences of visitors to online cancer communities. Methods: Twenty-three in-depth interviews were conducted with online cancer community visitors, including cancer survivors (n = 18), family members (n = 2), and individuals who were both a survivor and family member (n = 3). Interviews were analysed using a grounded theory approach. Results: A theory developed explaining how individuals ‘navigated’ the experience of cancer using online cancer communities. Online advice and information led participants on a ‘journey to become informed’. Online friendships normalised survivorship and cast participants on a ‘journey to recreate identity’. Participants navigated a ‘journey through different worlds’ as they discovered relevant and hidden communities. Conclusions: This theory highlights virtual paths people affected by cancer can take to self-manage their experience of the disease. Online community experiences can be improved by promoting online evaluation skills and signposting visitors to bereavement support. Implications for cancer survivors: Cancer survivors can benefit through both lurking and posting in online communities. However, individuals risk becoming distressed when they befriend individuals who may soon die. Additionally, people affected by rarer cancers can struggle to find shared experiences online and may need to look elsewhere for support

Chondrogenesis of Human Infrapatellar Fat Pad Stem Cells on Acellular Dermal Matrix

Acellular dermal matrix (ADM) has been in clinical use for decades in numerous surgical applications. The ability for ADM to promote cellular repopulation, revascularisation and tissue regeneration is well documented. Adipose stem cells have the ability to differentiate into mesenchymal tissue types, including bone and cartilage. The aim of this study was to investigate the potential interaction between ADM and adipose stem cells in vitro using TGFβ3 and BMP6. Human infrapatellar fat pad-derived adipose stem cells (IPFP-ASC) were cultured with ADM derived from rat dermis in chondrogenic (TGFβ3 and BMP6) medium in vitro for 2 and 4 weeks. Histology, qPCR, and immunohistochemistry were performed to assess for markers of chondrogenesis (collagen Type II, SOX9 and proteoglycans). At 4 weeks, cell-scaffold constructs displayed cellular changes consistent with chondrogenesis, with evidence of stratification of cell layers and development of a hyaline-like cartilage layer superficially, which stained positively for collagen Type II and proteoglycans. Significant cell-matrix interaction was seen between the cartilage layer and the ADM itself with seamless integration between each layer. Real time qPCR showed significantly increased COL2A1, SOX9, and ACAN gene expression over 4 weeks when compared to control. COL1A2 gene expression remained unchanged over 4 weeks. We believe that the principles that make ADM versatile and successful for tissue regeneration are applicable to cartilage regeneration. This study demonstrates in vitro the ability for IPFP-ASCs to undergo chondrogenesis, infiltrate, and interact with ADM. These outcomes serve as a platform for in vivo modelling of ADM for cartilage repair

Behavior of Reinforced Concrete Box Beam Strengthened with CFRP U-Wrap Strips Under Torsion

The present study focuses on the torsional strengthening behavior of reinforced concrete (RC) box section beams that are widely used in bridges. Four RC box beams were fabricated, and three of them were wrapped by carbon fiber-reinforced polymer (CFRP) U-wrap strips with or without longitudinal strips. The different wrapping configuration, cracking angle, failure pattern, and tensile strain of fibers were investigated and discussed accordingly. The experimental results addressed that U-wrap strips strengthening also can upgrade the ultimate torque of beams moderately. In particular, using U-wrap and longitudinal strips to bond the box beams increased the torsional stiffness slightly. The same equation from different codes for calculating RC specimens can accurately predict the ultimate strength of the control beam, but the calculation of the fib model overestimated the torsional strengthening improvement of the wrapped specimens. However, Ghobarah et al. assumed approximately 3000με of the average ultimate fiber strain in calculating the ultimate strength of the wrapped box beams which shows in relatively appropriate agreement with testing results

Effect of Diethylenetriamine and Triethylamine sensitization on the critical diameter of Nitromethane

In this work, the critical diameter for detonation was measured for Nitromethane (NM) sensitized with two different amines: Diethylenetriamine (DETA) and Triethylamine (TEA). The critical diameter in glass and polyvinylchloride tubes is found to decrease rapidly as the amount of sensitizer is increased, then increase past a critical amount of sensitizer. Thus the critical diameter reaches a minimum at a critical concentration of sensitizer. It was also found that the critical diameter is lower with DETA than with TEA

Purchasing power parity theory and its validity in Pacific Island countries

Among the 14 Pacific island countries (PICs), which are members of the inter- governmental organization known as Pacific Islands Forum, six countries have independent currencies five of them, namely Fiji, Samoa, Solomon Islands, Tonga and Vanuatu have fixed exchange rate regimes and the sixth country namely Papua New Guinea has a flexible exchange rate regime. The other eight are dollarized economies, having adopted one of the currencies of Australia, New Zealand and the United States. This paper investigates whether the purchasing parity power theory holds in regard to five countries under fixed exchange rate regimes. Our findings show that long-run PPP hypothesis hold for all five PICs.peer-reviewe

Evolved Navigation Control for Unmanned Aerial Vehicles

Whether evolutionary robotics (ER) controllers evolve in simulation or on real robots, realworld performance is the true test of an evolved controller. Controllers must overcome the noise inherent in real environments to operate robots efficiently and safely. To prevent a poorly performing controller from damaging a vehicle—susceptible vehicles includ
