The Representation of Ternate Oral Literature in The Perspective of Literary Ecology
Nowadays, ecology has developed rapidly since it is no longer limited to the study of ecosystems or nature, but also used to study other fields including in literary studies. Many scholars argue that literature is closely related and inseparable to ecology. The large number of literary works containing nature and the environment shows that the writers have cared for nature from a long time ago. The study aims to analyze the representation of Ternate oral literature in the perspective of literary ecology. This study apllies descriptive qualitative method. Technique data collection used is documentation technique. Sources of data for this study were obtained from various sources of Ternate oral literature documents found in libraries and other relevant sources. In addition, the researchers used browsing’ techniques to find relevant data. Triangulation techniques are still used to check valid data from various sources. The result shows that the representation of Ternate oral literature viwed from ecological perspective is shown in the form of fables and poetry (dola bololo, dalil moro, and dalil tifa) which implie moral and ethical values to become lessons for the community and readers of literature. In addition, the implied message from fables and poetry in Ternate oral literature is that living things and their natural environment play a role in life and also influence the thinking of the people of Ternate which of course must be maintained and preserved because they are useful for the community itself
Inflation hedging with commodities: A wavelet analysis of seven centuries worth of data
© 2019 Elsevier B.V. We perform a test of the inflation hedging properties of commodities on the longest data series ever used for this purpose. We apply wavelet analysis to commodity prices and inflation data from the United Kingdom for the years 1265 through 2017, to detect co-movement across different times and frequencies. We demonstrate robust inflation hedging properties of agricultural, energy, and industrial commodities for the 4- to 8-year horizon through almost the entire seven centuries
Commodity financialisation and price co-movement: Lessons from two centuries of evidence
© 2020 The recent development of financialisation is argued to have led to an unprecedented rise in the dependence between commodity returns. Using 170 years’ worth of data and several novel dependency measures, we demonstrate that the recent cross-commodity correlations are neither unprecedented nor unique. Similar episodes have occurred multiple times throughout history, even as far back as the 19th century, and these events usually coincide with major economic disruptions. There is no long-run increase in the co-movement of commodity returns. Our results cast doubt on the link between the recent peak in cross-commodity correlations and market financialisation
Comovements between Heavily Shorted Stocks during a Market Squeeze: Lessons from the GameStop Trading Frenzy
We examine the comovements between stock prices of different heavily shorted companies during a short-squeeze incident. Using the recent GameStop trading frenzy as a case study, we employ wavelet coherence analyses to determine its link with other frequently shorted stocks. We demonstrate a robust positive association between GameStop prices and the performance of high short interest indices. The bubble behavior driven by retail investor herding transmits between different stocks, even from unrelated sectors. Consequently, a single short-squeeze incident may build up into a potentially broader systemic risk, casting doubt on market integrity and stability
Spillover and risk transmission in the components of the term structure of eurozone yield curve
The components of term structure of interest rate are an important element of the asset pricing models. This article studies the connectedness of the component of the sovereign yield curve across eleven earliest members of the Eurozone comprising six core countries (Germany, Netherlands, Finland, Austria, Belgium, France) and five peripheral countries (Greece, Ireland, Italy, Portugal and Spain) thus enabling us to analyse the short-, medium- and long-term yield curve dynamics of these eurozone economies. We document three distinct phases of connectedness described by the early eurozone period, global financial crisis and the European sovereign debt crises, and the period afterwards. We find a higher level of connectedness between the countries before the global financial crisis, which decreased to its lowest levels during the European debt crisis and is now rising back to higher levels following the European debt crisis. We find that, in general, the core countries are net transmitter of spillover, whereas, the peripheral countries are net receivers of spillover for the three components of the yield curve
Seven centuries of commodity co-movement: a wavelet analysis approach
© 2020 Informa UK Limited, trading as Taylor & Francis Group. We examine interdependencies between agricultural, industrial, and energy commodity price indices suing data sets from more than seven centuries. To this end, we apply wavelet coherence and wavelet phase difference. There is a high coherence between prices for all three commodity-groups with energy prices now leading both agricultural and industrial commodity prices. Also, the role of energy as a leading series has increased over time
Is there an illiquidity premium in frontier markets?
© 2019 The Authors We perform a comprehensive examination of the role of stock-level liquidity in the cross-section of frontier market stock returns. Using several popular liquidity measures and a battery of asset pricing tests, we investigate the illiquidity premium in 22 countries for the years 1991–2019. Contrary to typical relationships in developed and emerging markets, we find no evidence of illiquidity premium in frontier equities. Our findings support the hypothesis that for countries not fully integrated with the global economy, the diversification benefits offset the illiquidity, which, in turn, proves less important
An Investigation of the Potentials of 2-[(2-Hydroxyphenyl) Methylidene] Hydrazine-1-Carbothioamide and its Mn(II) and Zn(II) Complexes as Antimicrobial Agents
Antibiotic resistance as a result of misuse, overuse or abuse of drugs is an issue of serious concern world over. The quest for more active and robust antimicrobial agents remains a scientific challenge and requires multimillion-dollar investment in the area of drug design and development. Here in, we report the synthesis and characterisation of a tridentate thiosemicarbazone (2-[(2-hydroxyphenyl)methylidene]hydrazine-1-carbothioamide) (HL) from salicylaldehyde and thiosemicarbazide. Its complexes with Mn(II) and Zn(II) were prepared following similar technique and characterised by melting point, FT-IR, UV –visible spectrophotometry, and elemental analysis. The Mn(II) complex showed paramagnetism with a magnetic moment value of 5.80 BM while the Zn(II) complex was diamagnetic. Both complexes were nonelectrolyte with molar conductivities below 2 ohm–1cm2mol–1. The potentials of the compounds as antibacterial and antifungal agents were investigated against three bacterial: Staphylococcus aureus, Escherichia coli and Salmonella typhi, and two fungal: Aspergillus flavus and Mucor indicus isolates. Interestingly, all the compounds showed medium to high activities against the tested isolates (except for the Mucor indicus which resisted all the compounds) and hence their potential as antimicrobial agents.Keywords:   Thiosemicarbazone; Mn(II) and Zn(II) Complexes; Antibacterial; Antifungal; Antibiotic resistanc
ATTAINING MEANINGFUL LEARNING OF ECOLOGICAL CONCEPT: A TEST OF THE EFFICACY OF 7E LEARNING CYCLE MODEL
This study explored the efficacy of the 7E learning cycle model on students’ achievement and retention ability in ecology. The study employed a quasi-experimental research design. A total of seventy-five (75) SSII biology students drawn from two purposively sampled schools in Education District V of Lagos state formed the sample of the study. Ecology Achievement Test (EAT) was used for data collection. An expert in test and measurement and a biology teacher validated the achievement test. The reliability coefficient of the EAT was determined to be 0.80 using the split-half reliability coefficient. One research question was raised and three hypotheses were tested at a 0.05 level of significance and data were analyzed using analysis of covariance (ANCOVA). The results revealed a significant main effect of the 7E learning cycle on students’ achievement in ecology[F (1,72) = 0.00; p< .05), the study also revealed that there was a significant difference in students’ retention ability [F (1,72) = 0.03; p< .05) in favour of the group taught using 7E learning cycle and there was no gender influence on the achievement of students taught using the 7E learning cycle. Based on the findings it was concluded that the 7E learning cycle model is a potent strategy that offers a glimmer of hope that the problem of underperformance in ecological concepts can be changed for the better. Therefore, it was recommended amongst others that the use of the 7E learning cycle as an instructional strategy should be explored by teachers to enhance meaningful learning of difficult concepts in biology
