The phenomenon of Decision Oscillation: a new consequence of pathology in Game Trees
Get PDFRandom minimaxing studies the consequences of using a random number for scoring
the leaf nodes of a full width game tree and then computing the best move using the
standard minimax procedure. Experiments in Chess showed that the strength of play
increases as the depth of the lookahead is increased. Previous research by the authors
provided a partial explanation of why random minimaxing can strengthen play by showing
that, when one move dominates another move, then the dominating move is more likely
to be chosen by minimax. This paper examines a special case of determining the move
probability when domination does not occur. Specifically, we show that, under a uniform
branching game tree model, whether the probability that one move is chosen rather than
another depends not only on the branching factors of the moves involved, but also on
whether the number of ply searched is odd or even. This is a new type of game tree
pathology, where the minimax procedure will change its mind as to which move is best,
independently of the true value of the game, and oscillate between moves as the depth of
lookahead alternates between odd and even

Maritime temporalities and Capitalist development
Get PDFThis intervention develops arguments in our book Capitalism and the Sea on the complex temporalities attached to capitalism's intense and peculiar relationship to the global ocean. Technological innovations like the steamship or containerisation plainly transformed the pace and intensity of maritime commerce, and aspects of the global economy. We take this further to argue that the very origins and periodisation of capitalism are connected to the global ocean; as will be our futures, given the unpredictable implications of the oceans acting as the biosphere's 'heat sink'. We consider several stylised expressions of time at sea: deep-time, logistical-time, life-time, and revolutionary time suggesting that the ocean world as a geographical space articulates these in distinctive and contradictory ways
Managing cybersecurity threats and increasing organizational resilience
Get PDFCyber security is high up on the agenda of senior managers in private and public sector organizations and is likely to remain so for the foreseeable future. Because cyber-attacks are increasing in sophistication and are of a persistent nature, it is clear that those undertaking research into counteracting cyber threats should familiarize themselves with the types of vulnerability that are likely to be exploited and develop workable solutions. This means working with likeminded people that are intent on ensuring that those carrying out such attacks do not succeed. It is because of the complexity and width of the problem that it is unlikely that those working in a single discipline will be able to solve the recurring problems that managers face. Indeed, the nature of connectivity and interactivity requires that cyber security researchers adopt an inter-disciplinary and/or multi-disciplinary approach to solving cyber security problems, and also that academic and industry researchers cooperate in order to work on cyber security solutions that can be applied across all industry sectors.
This Special Issue draws on the knowledge of various cyber security experts from a range of disciplines who address a number of issues and put forward solutions that utilize cyber security intelligence, with the aim of making organizations more resilient and able to withstand different types of cyber-attack. This means that studying the problem from various perspectives and establishing the breadth and depth of the problem are key priorities. The collection of papers in this Special Issue will help broaden the scope of the subject matter and through interpretation will offer recommendations for dealing with known cyber threats

Rules vs. Principles in POSI
No full textThis post looks towards a distinction between “rules” and “principles” that I believe are fundamental to the systems that POSI wishes to implement. People have begun treating the example specifications in POSI as though they were hard-and-fast rules. For example, the wind-down contingency clause specifies “12 months” – and people can become very anxious about strictly fulfilling this criterion
Connecting to AWS OpenSearch Serverless using Python
No full textI recently wanted to use ElasticSearch (or OpenSearch as Amazon terms it from the fork) in an AWS environment, using Python. When I tried to connect I got a very painful 403 Forbidden error. Specifically: opensearchpy.exceptions.AuthorizationException: AuthorizationException(403, ‘Forbidden’).
The answer I needed was eventually here: https://opensearch.org/docs/latest/clients/python-low-level/. The key point is that, when using serverless, the service is not “es” but “aoss” (Amazon OpenSearch Serverless
Covid-19 lockdown UK adult experiences - Preliminary results
Get PDFThanks for taking a look at this summary of the preliminary results from our UK COVID-19 Lockdown Adult Experiences survey conducted between March 2022 and June 2022. Here we summarize the responses given by the 1,330 adults in the UK who participated in our nationwide survey.
We have released a parallel report on the results from our UK COVID-19 Lockdown Experiences survey for LGBTQ+ respondents on our website

Impact Of Bank’s Customer Relationship Management on Customer Satisfaction and Loyalty of SMEs: The Moderating Role of Advisory Services and Capacity Building
No full textThe aim of this study was to investigate how Customer Relationship Management (CRM) - encompassing customer focus, knowledge management, CRM organization, and technology use -impacts customer satisfaction and loyalty. Additionally, the study explored the relationship between customer satisfaction and loyalty and evaluated the role of advisory services and capacity building in
moderating the relationship between CRM and customer satisfaction, as well as the moderating role of trust in the relationship between customer satisfaction and loyalty. The study employed a mixed methods approach, with a sample of 500 respondents selected using a purposive sampling method.
The findings revealed that CRM is positively correlated with customer satisfaction, and that customer satisfaction is also positively related to customer loyalty. Furthermore, capacity building moderated the relationship between CRM and customer satisfaction, while trust moderated the relationship between customer satisfaction and loyalty. The study recommends that banks prioritize a customer�centric strategy, with a focus on offering advisory services and capacity building to attract, groom and retain corporate customers. Additionally, banks must engage with SMEs to better understand their needs and translate customer data into service delivery to achieve greater customer satisfaction
