ANGELIKA VAN DE LINDE, STATISTICIAN, CO-DEVELOPER OF THE DEVIANCE INFORMATION CRITERION, DIC

 



     Angelika van der Linde was my much valued colleague at the University of Edinburgh during the late 1990s before moving on to a professorial position at the University of Bremen. She is a fine mathematical statistician, perhaps best known for her development  with Spiegelhalter, Best, and Carlin of the Deviance Information Criterion DIC. This widely applied method for choosing between statistical models was developed as a sophisticated approximation to AIC, as developed by my friend Hirotugu Akaike, who spent a year visiting the University of Wisconsin-Madison (1981-82). 



                                                       

                                            My friends Hirotugu and Mituko Akaike
                        

                                 

                                                ANGELIKA'S RESEARCH WORKS

         Angelika has also made pivotal contributions to the theory and application of splines. We still correspond every Christmas,. My best wishes to Angelika and her husband during the pandemic.

PRE-CLASSICAL AND ANCIENT HISTORY

There are archaeological remains from the Helladic period, contemporary with the Minoans. There is archaeological evidence of Kythiran trade as far as Egypt and Mesopotamia.

Kythira had a Phoenician colony in the early archaic age; the sea-snail which produces Tyrian purple is native to the island.[citation needed]Xenophon refers to a Phoenician Bay in Kythira (Hellenica 4.8.7, probably Avlemonas Bay on the eastern side of the island). The archaic Greek city of Kythira was at Scandea on Avlemonas; its ruins have been excavated. Its acropolis, now Palicastro (Palaeocastron, "Old Fort"), has the temple of Aphrodite Ourania, who may well represent a Phoenician cult of Astarte.

In classical times, Kythira was part of the territory of several larger city-states. Sparta took the island from Argos early in the sixth century, and ruled it under a kytherodíkes (kυθηροδίκης, "judge on Kythira"), in Thucydides' time [4,53,3]; Athens occupied it three times when at war with Sparta (in 456 during her first war with Sparta and the Peloponnesians; from 426 to 410, through most of the great Peloponnesian War; and from 393 to 387/386, during the Corinthian War against Spartan dominance) and used it both to support her trade and to raid Laconia.

Kythira was independent, and issued her own coins in 195 after the Achaean defeat of Sparta. In Augustus' time, it was again subject to Sparta, being the property of Gaius Julius Eurycles, who was both a Spartan magnate and a Roman citizen.

By this time, the Greek cities were in practice subject to the Roman Empire. Kythira continued to exist under the Roman Empire and its Byzantine successor state for centuries. Christianity is attested from the fourth century AD, the time of Constantine; according to her legend, Saint Elessa came from Laconia to convert the island.

SURVIVAL OF THE PENGUINS a poem by Tom Leonard

                                                    SURVIVAL OF THE PENGUINS

                                                                by Tom Leonard






                          "THE GREAT GOD BRIAN SEAGULL WILL  PROTECT US!"

                    CRIED SANCHO, THE BIG FAT KING EMPEROR,

                     AS THE TSUNAMIS CRASHED TOWARDS THE ANTARCTIC SHORE

                         

                           "FEEL LOVE NOT FEAR!" ENJOINED QUEEN ISABELLA,

                    WHEN  THE METEORITE VAPORISED O'ER THE POLE.

                   

                           "ALL TWENTY MILLION OF US MUST HIDE",

                    DECLARED STATISTICIAN FLOSSY FLO,

                           "IN ATLANTIS BELOW THE ICE,

                            "LEST WE TRAVEL WITH THE HUMANS TO THE STARS."


                    THE MOTHER PENGUINS FROM THE ROOKERY ON BIRD ISLAND

                     GUIDED THEIR YOUNG THROUGH THE LABYRINTH OF PINGU

                      TO THE HIDDEN CITY,

                     WHERE ANCIENT PETRELS STILL FLOURISHED WAY BENEATH.

                      

                      CHILLY WILLY  LED THE WAY FROM HALLEY,

                      FEATHERS MCGRAW NAVIGATED FROM  ROTHERA            ,

                      AND  MUMBLE SLITHERED ALL THE WAY FROM SIGNY.


                      THE HUMANS EVAPORATED IN THEIR SHIVERING BASES

                      IN THE GLOW OF THE METEORITE

                      THAT DESTROYED THE ENTIRE ICECAP,

                      AS THE TEN MILE HIGH TSUNAMIS STRUCK.


                      BUT |ATLANTIS ROSE TO THE SURFACE

                      WHEN THE FURORE SUBSIDED,

                      AND TWELVE TUBE-NOSED, GIANT PETRELS 

                      AND TEN THOUSAND PENGUINS EMERGED

                       INTO THEIR BRAVE,  NEW, HUXLEYIST WORLD

                       WHERE EUGENICS STILL RULED,

                        CARRYING THE BONES OF SANCHO AND ISABELLA

                        ON A SHIP-SHAPED HEARSE. 



                              MAYBE THEY'LL DO BETTER THAN THE  SURVIVING,

                       OMICRON-STRICKEN HOMO SAPIENS ON NEW JERSEY, 


                        THOUGHT THE ONE AND ONLY CREATOR GOD BRIAN SEAGULL,

                        HOVERING IN HIS SEVENTH HEAVEN ABOVE.


                             PERHAPS THEY'LL MATCH THE ORIGINAL HOMINIDS,

                         COMING IN FROM PLANET BORN AGAIN.

                             MOTHER EARTH MAY WELL RECOVER AGAIN.

ON SELF DIAGNOSING YOUR EXPECTED TIME TO A FIRST COVID INFECTION by Tom Leonard

                            



Omicron Alert: For a randomly chosen person in Scotland the chance of becoming infected with some sort of Covid on any particular day is currently (10th December 2021) about 1 in 1000 and rising. Please try to assess your own risk. The following procedure may help:


                                             A SIMPLE SELF DIAGNOSTIC TOOL


CONSIDER THE IDEALIZED ASSUMPTIONS THAT ON ANY PARTICULAR DAY  , YOU 

WILL, WITH PROBABILITY  P=1/2000, BE INFECTED WITH COVID, WHERE INFECTIONS 

ON DIFFERENT DAYS ARE TAKEN TO OCCUR INDEPENDENTLY.


       LET   N=NUMBER OF DAYS UNTIL YOUR FIRST INFECTION


      THEN N POSSESSES A PROBABILITY DISTRIBUTION WHICH IS

    GEOMETRIC WITH PROBABLITY  P=1/2000



      IN PARTICULAR, THE MEAN OR EXPECTATION OF N IS


                                 E(N)= 2000

     

 AND THE STANDARD DEVIATION OF N IS, TO A CLOSE APPROXIMATION

                                

                                ST.DEV. (N)= 2000


IF, FOR EXAMPLE, YOU ARE WORKING IN RETAIL AND YOUR CUSTOMERS ARE NOT

COMPELLED TO WHERE MASKS, THEN THE DAILY PROBABILITY OF INFECTION P

 COULD BE MUCH HIGHER THAN IF YOU ARE WORKING FROM HOME

              

         IF FOR EXAMPLE, P=1/100, THEN YOUR EXPECTED NUMBER OF DAYS TO  FIRST

  INFECTION   IS E(N)=100 WITH APPROXIMATE STANDARD DEV IATION 100.


        IF YOU HAVE BEEN DOUBLY VACCINATED THEN YOU COULD CONSIDER DIVIDING 

YOUR SUBJECTIVE ASSESSMENT OF  P  BY  9.  IF P=1/900. THEN E(N)=900 WITH 

APPROXIMATE STANDARD DEVIATION 900.


        THIS PROVIDES A SIMPLE WAY OF THINKING ABOUT YOUR CHANCES OF INFECTION.

       A BASELINE POPULATION VALUE OF P  IS

       P*=  NUMBER OF DAILY INFECTIONS / POPULATION SIZE

       FOR EXAMPLE.,IF THE NUMERATOR AND DENOMINATOR ARE RESPECTIVELY

      3000 AND 6000000,  THEN P*=1/2000


       WHEN SUBJECTIVELY ASSESSING YOUR OWN P YOU COULD C ONSIDER HOW 

MUCH AT RISK YOU ARE RELATIVE TO A RANDOMLY SELECTED MEMBER OF THE 

POPULATION WITH P=P*.


PROBABILITIES FOR GEOMETRIC DISTIBUTION

       NOTE THAT     

      F(n)  = Prob (N>n)  can be calculated as the nth power of 1-P, for your subjective choice of P

        You can therefore easily calculate your probability of not being infected with COVID during the next n days, for any specified value of n 




  (Approximate) Quartiles:  The first or lower (approximate) quartile Q1 of N is the value of n such that F(n)=3/4.                                  

                         Therefore

                                      Q1= log (3/4) / log (1-P).

where log denotes the natural logarithm

                         Similarly, the second (approximate) quartile, or median of N is

                                     Q2= log (1/2)/log (1-P)

  

                          and the third or upper (approximate) quartile of  N is

  

                                     Q3= log (1/4)/log (1-P)

SCARY POLITICS IN THE SOLOMON ISLANDS








ACCORDING TO VIJAY PRASHAD (THREAD READER 26 NOV 2021) A dangerous situation is afoot in the Solomon Islands. A coup is on with the government of Manasseh Sogavare threatened with overthrow by a revolt in Malaita, pushed by the U.S. and Australia Australian troops have arrived in Honeira, the capital of the Solomon Islands. PM Scott Morrison says that they will only be there for ‘weeks’. We shall see. This intervention has been planned for years, since Solomon Islands recognized Beijing over Taipei in September 2019. When Sogavare switched his link to China, the U.S., driven by Marco Rubio, and other violators of international sovereignty, built a coalition of anti-communists and pro-Zionist Christians. See the Israeli flag held by those making the coup


      WHILE I'M BY NO MEANS A MARXIST, PROFESSOR PRASAD'S VIEWPOINT SEEMS TO MAKE GOOD SENSE. WHY ELSE WOULD THE AUSTRALIANS BE INTERFERING? THEY HAVE A HORRIFIC HISTORICAL: REPUTATION e.g. BECAUSE OF THEIR ABUSE OF INDIGENOUS PEOPLE IN AUSTRALIA AND THE SURROUNDING ISLANDS, THEIR ABUSE OF ORPHANS FROM BRITAIN, AND THEIR ABUSE OF THEIR OWN LGBT PEOPLE. WHY SHOULD THIS BE ANY DIFFERENT?

Post-conflict era[edit]

Kemakeza remained in office until April 2006, when he lost the 2006 Solomon Islands general election and Snyder Rini became PM. However allegations that Rini had used bribes from Chinese businessmen to buy the votes of members of Parliament led to mass rioting in the capital Honiara, concentrated on the city's Chinatown area. A deep underlying resentment against the minority Chinese business community led to much of Chinatown in the city being destroyed.[81] Tensions were also increased by the belief that large sums of money were being exported to China. China sent chartered aircraft to evacuate hundreds of Chinese who fled to avoid the riots.[citation needed] Evacuation of Australian and British citizens was on a much smaller scale.[citation needed] Additional Australian, New Zealand and Fijian police and troops were dispatched to try to quell the unrest. Rini eventually resigned before facing a motion of no-confidence in Parliament, and Parliament elected Manasseh Sogavare as Prime Minister.[82][83]

Sogavare struggled to assert his authority and was also hostile to the Australian presence in the country; after one failed attempt, he was removed in no confidence vote in 2007 and replaced by Derek Sikua of the Solomon Islands Liberal Party.[84] In 2008 a Truth and Reconciliation Commission was established to examine and help heal the wounds of the 'tension' years.[85][86] Sikua lost the 2010 Solomon Islands general election to Danny Philip, though after a vote of no confidence in him following allegations of corruption, Philip was ousted and replaced by Gordon Darcy Lilo.[87][88] Sogavare returned to power after the 2014 election, and oversaw the withdrawal of RAMSI forces from the country in 2017.[74] Sogavare was ousted in a no confidence vote in 2017, which saw Rick Houenipwela come to power, however Sogavare returned to the Prime Ministership after winning the 2019 election, sparking rioting in Honiara.[89][90] In 2019 Sogavare announced that the Solomons would be switching recognition from Taiwan to China.[91][92]

In November 2021 there was mass rioting and unrest.[93]
