Chemically induced phosphorescence from manganese(II) during the oxidation of various compounds by manganese(III), (IV) break and (VII) in acidic aqueous solutions

Chemiluminescence was observed during the manganese(III), (IV) and (VII) oxidations of sodium tetrahydroborate, sodium dithionite, sodium sulfite and hydrazine sulfate in acidic aqueous solution. From the corrected chemiluminescence spectra, the wavelengths of maximum emission were 689±5 and 734±5 nm when the reactions were performed in sodium hexametaphosphate and sodium dihydrogenorthophosphate/ orthophosphoric acid environments, respectively. The corrected phosphorescence spectrum of manganese(II) sulfate in a solution of sodium hexametaphosphate at 77 K exhibited two peaks with maxima at 688 and 730 nm. The chemical and spectroscopic evidence presented strongly supported the postulation that the emission was an example of solution-phase chemically induced phosphorescence of manganese(II) thereby, confirming earlier predictions that the chemiluminescence from acidic potassium permanganate reactions originated from an excited manganese(II) species.

The power of play-break for automatic detection and browsing of self-consumable sport video highlights

To enable content-based retrieval, highlights extraction from broadcasted sport video has been an active research topic in the last decade. There is a well-known theory that high-level semantic, such as goal in soccer can be detected based on the occurrences of specific audio and visual features that can be extracted automatically. However, there is yet a definitive solution for the scope (i.e. start and end) of the detection for self consumable highlights. Thus, in this paper we will primarily demonstrate the benefits of using play-break for this purpose. Moreover, we also propose a browsing scheme that is based on integrated play-break and highlights (extended from [1]). To validate our approach, we will present the results from some experiments and a user study.

How using a wiki can help break the ice between cultures

In this paper, we describe how a wiki has been used to help break the ice between cultures in an online subject. The number of International student enrollments has been on the increase in recent years and therefore the student demographics within the classroom have changed. It is the intension of this paper to show how a wiki has been implemented to promote interaction between students from different cultures.

Revisiting the US money demand function: an application of the Lagrange multiplier structural break unit root test and the bounds test for a long-run relationship

In this article, we examine the issue of a levels relationship and stability of the US money demand function over the period 1959:01 to 2004:02. We use the Lagrange multiplier structural break unit root test and the bounds testing approach to a long-run relationship in levels of the variables, namely real money demand, nominal interest rate and real income. We find greater evidence for a long-run relationship in levels and stability of the US money demand function when we use M2 as a proxy for money demand. However, we find little evidence for a long-run relationship between M1 and M2 with their determinants for the recent period, spanning the last decade or so.

Mean reversion versus random walk in G7 stock prices evidence from multiple trend break unit root tests

This paper provides evidence on the random walk hypothesis in G7 stock price indices using unit root tests which allow for one and two structural breaks in the trend. Of the seven countries we find, at best, evidence of mean reversion in the stock price index of Japan. Thus, overall, our results support the random walk hypothesis. We also consider the implications of the identified structural breaks for movement in stock prices over time. Our main conclusion from this exercise is that the second break in stock prices has had a detrimental effect on movements in stock prices in the G7 countries.

Creating the political will necessary for achieving multilateral disarmament : the need for a peace-industrial complex

This dissertation deals with the failure to end the central arms race and provides some alternative proposals. Chapters 1 and 2 look at the failure of governmental disarmament negotiations and the ineffectiveness of the non-governmental peace movement. Chapter 3 outlines the author's recommended comprehensive strategy for ending the arms race? both the need for the US to make a dramatic unilateral initiative to break the deadlock (Super GRIT) and a detailed disarmament treaty. The main problem, as argued by the author, is more one of political will and so it is necessary to find a way of creating the political will to stimulate the US to make that dramatic unilateral initiative. He calls for the creation of a Peace-Industrial Complex. The intellectual arguments for the potential basis of such a complex are to be found in the research done by the United Nations; this is examined throughout Part II (Chapters 4-7). Unfortunately very little attention has been paid by governments to this work. Part III (Chapters 8 and 9) deals in more detail with the recommended Peace-Industrial Complex. Chapter 8 looks at its possible creation and method of work. Chapter 9 suggests that the proposed complex creates a transcending vision: from ‘uclear winter’to ‘nuclear spring’.

Ned Kelly wallpapers: Spring variation 2008

The simple abstractions of the Ned Kelly Wallpaper Series attempt to take some of the puff out of the larrikin myth that surrounds the Ned Kelly figure These paintings destabilise the heroic expressionist gesture (beloved of Sidney Nolan) as modest pattern - as one of the many avaìlable patterns of history

The structure of tourist expenditure in Fiji : evidence from unit root structural break tests

The central aim of this paper is to investigate whether shocks to Fiji's tourism industry have a permanent effect or a transitory effect on tourist expenditure in Fiji. To accomplish this aim the Zivot and Andrews (1992) one break test and the Lumsdaine and Papell (1997) two break tests are used. The one break and two break tests reveal 1987 - the year of the military coups in Fiji - as the year of the break. Moreover, it is possible to reject the unit root null leading to the conclusion that shocks to Fiji's tourism industry have a transitory effect on tourist expenditure in Fiji.

Are OECD stock prices characterized by a random walk? Evidence from sequential trend break and panel data models

This paper examines whether stock prices for a sample of 22 OECD countries can be best represented as mean reversion or random walk processes. A sequential trend break test proposed by Zivot and Andrews is implemented, which has the advantage that it can take account of a structural break in the series, as well as panel data unit root tests proposed by Im et al., which exploits the extra power in the panel properties of the data. Results provide strong support for the random walk hypothesis.
