Abstract: A frequent criticism of unit root tests concerns the poor power and size properties that many of such tests exhibit. However, the past decade or so intensive research has been conducted to alleviate these problems and great advances have been made. The present paper provides a selective survey of recent contributions to improve upon both size and power of unit root tests and in so doing the approach of using rigorous statistical optimality criteria in the development of such tests is stressed.

Econometric Theory, 1995

In the context of testing for a unit root in a univariate time series, the convention is to ignore information in related time series. This paper shows that this convention is quite costly, as large power gains can be achieved by including correlated stationary covariates in the regression equation. The paper derives the asymptotic distribution of ordinary least squares (OLS)

We revisit estimation and computation of the Dickey Fuller (DF) and DFtype tests. Firstly, we show that the usual one step approach, based on the ”DF autoregression”, is likely to be subject to misspecification. Secondly, we clarify a neglected two step approach for estimation of the DF test. (In fact, we introduce a new two step DF autoregression.) This method is always correctly specified and efficient under the circumstances. However, it is either neglected or misused in unit root testing literature. The commonly employed hybrid of the (correct) two step method is shown to be inefficient, even asymptotically. Finally, we further improve/robustify the proposed two step method by employing the missing initial observations. Our finally proposed method is to be used in unit root testing, since it is a new DF autoregression that retains the missing observations.

1835 Petty Session Courts, West Cork Returns, 2024

This had been abstracted from the Irish annual return. In between details of the court returns is a sampling of some of the local Magistrates who sat. Since the mid 17th century the Magistrates of West Cork were overwhelmingly Protestant bar a bried period around 1680 and the first Catholic to be appointed was Daniel O'Sullivan, Cameatringen, Berehaven, Co. Cork, 1814, Died On Passage from Bristol Where he Had Been for the Recovery of His Health, D. O'Sullivan, Cameatringen, Berehaven, Co. Cork, First Catholic Appointed Magistrate since Reign of Queen Anne, Captain of Berehaven Loyal Infantry, Descended From One of The Princely Branches of O'Sullivan Beare. O'Sullivan, Daniel (1758/61?–1814), middleman and magistrate, was second son of Daniel O'Sullivan and his wife Honora, daughter of Morgan O'Connell (1739–1809) of Carhen, Cahirciveen, Co. Kerry, and therefore first cousin to Daniel O'Connell (qv). On his father's side he was grandnephew to Morty (Murtagh) Óg O'Sullivan, a smuggler shot at Eyries, Co. Kerry, while resisting arrest for homicide in 1754. The family resided in Caretringane House, Castletownbere, Co. Kerry, and leased a sizeable property in the Coulagh area on the Eyre estate. Their uncle's fate did not deter the family from the smuggling tradition, though the French traveller Coquebert de Montbret commented on the social pretensions of the family in 1791. Following the death (c.1796) of his elder brother, John, Daniel was vested with administration of the estate until his nephew, Morty O'Sullivan (d. 1825), should come of age. In December 1796, when French vessels belonging to the expeditionary force under Gen. Lazare Hoche (1766–97) were observed anchored off Bere Island, O'Sullivan with great alacrity initiated a state of emergency in the district, ordering his tenants to drive cattle inland and to conceal provisions in the event of a French landing. Having posted a large number of tenants to watch the coast for the next eleven days, he took prisoner the crew of a French longboat reconnoitring the beaches and rushed them for interrogation to the nearest British garrison in Bantry. O'Sullivan was applauded for his loyalty, made captain of the Berehaven loyal infantry corps of yeomanry, and presented with the freedom of Cork city – the first catholic to receive the honour since the early 1700s. Recommended to the commission of the peace by the county governors, he was the first catholic to be made a magistrate in Co. Cork since the early 1700s. In recognition of his part at the time of the attempted French Invasion at Bantry Bay in 1796. The Magistrates were drawn from the ranks of the Landlords or their agents. Many had a well deserved reputation of being sectarian and partisan so slowly the British administration introduced Resident Magistrates initial former RIC inspectors to retired British army officers. Edith Somervill ‘The Irish RM probably accurately depicts the. None of the Magistrates had any legal training, a situation that still pertains in England. The situation improved towards the end of the 19th century as many of th RM were either barristers or solicitors. This was part of the radical overhaul of the Irish Justice system post Independence ebay the Free State Government. They abolished the Magistrates who still sit in Northern Ireland, This was praised by the former Lord Chancellor Ignatious O’Brien, (Baron Shandon 1857-1930). When the lord chancellor, Redmond John Barry, retired in 1913 O'Brien was appointed to the vacant post. While he was a hard worker he was neither diplomatic nor forceful enough to be truly effective, and was notorious for his long-winded and self-important judgments. His judicial philosophy favoured sweeping aside precedent and technicalities in favour of substantive justice as he saw it; hence he was on good terms with Peter O'Brien (qv), though he disapproved of his politics, and at odds with Christopher Palles (qv), though he acknowledged Palles's eminence as a jurist. He greatly enjoyed the social side of his office and the ceremonies and amusements of the viceregal court. O'Brien was nearly ousted as lord chancellor in 1915 in favour of James Campbell (qv) by the first coalition government – his removal was also sought by T. M. Healy and William O'Brien (qv) (1852–1928) – but was retained after a public outcry orchestrated by the Redmondites, which threatened to affect American public opinion. He expressed guarded optimism for the future of the Irish Free State, and admired the government of W. T. Cosgrave (qv), praising such decisions as the replacement of JPs by paid district justices and the creation of an unarmed police force. He emerges from its pages as a sensitive and somewhat neurotic meritocrat, haunted at the sufferings inflicted

Legal, Safety, and Environmental Challenges for Event Management, 2020

Risk management is a key requirement in the events industry today. All elements in event delivery have to be considered in the decision to deliver the event during the planning phase, and this information has to be shared with all the stakeholders so that they are able to input it to the document. The chapter highlights useful models such the EMBOK and also the five-step process to enable both practitioners and those wishing to gain a greater knowledge and understanding on what can potentially be a complex area. This is further supported with a body of knowledge of those who have written in the area and support some the ideas that have been presented.

The book An Introduction to VLSI Technology contains only nine chapters with comprehensive material, discussed in a very systematic, elaborative and lucid manner. The authors of this book have made sincere efforts in bringing the book very up to date. It will prove to be good text book for B.E./B.Tech students of all the engineering colleges in India as well as well as for the Researchers in the field of Electronics. It will also cater to the needs of the students of M.Sc. (Physics specialization in Electronics), M. Tech (Electronics) etc.
