In particular, I must thank the sponsors and advertisers, without whose support this Yearbook would not be possible. 2020 must have been the year that no-one expected in the early hours of 1 January as they celebrated its arrival. According to the Collins Dictionary, the word ‘lockdown’ had a 6,000 percentage increase in usage since 2019 The other pandemic-related words on the dictionary’s list of the top 10 words for 2020 were: ‘coronavirus’, ‘social distancing’, ‘self-isolate’, ‘furlough’, and ‘key worker’, which saw a 60-fold increase in usage over the previous year. Other top-10 words were ‘BLM’ (Black Lives Matter), ‘Megxit’ (the Duke and Duchess of Sussex withdrawing from royal duties), ‘mukbang’ (where a video or webcast host eats lots of food for the entertainment of viewers), and ‘TikToker’ (someone who regularly shares or appears in videos on TikTok). They might perhaps have added phrases such as ‘working from home’, which many office staff have done for large parts of 2020, and ‘you’re still muted’, a phrase I’ve heard so many times on Zoom and Teams calls this year, or ‘the new normal’, which has probably become overused. But in this year of lockdowns and working from home, it’s always good to have news of a new baby in the family. And that’s what we got in the spring when IBM shared the news about its two new mainframe products, the z15 Model T02 and LinuxONE III Model LT2. The highlight of the 2019 z15 Model T01 and Linux-ONE III LT1 was their outstanding feature allowing data to be ‘encrypted everywhere’, both in transit and at rest, without impacting system performance. This used the, so called, Data Privacy Passports. Other standout features were increased physical compute capacity, high availability options, and support for container-based development and applications (using the Red Hat OpenShift Container Platform). The Arcati Mainframe Yearbook 2021 This year’s z15 Model T02 and LinuxONE III LT2 Mark Lillycrop Publisher: products included those same features, but were Editorial Director: Trevor Eddolls Contributors: BMC, Deborah Carbo, Model9 different in their size and capacity.

In addition, both systems support IBM’s pre- packaged Cloud Paks. These include a secured © Arcati Limited, 2021 3 Arcati Mainframe Yearbook 2021 Mainframe Strategy Kubernetes container and containerized IBM middleware designed to let customers quickly use enterprise-ready containers. IBM has standard Cloud Paks for data, application integration, automation, and multi-cloud management and security. This will help customers develop, deploy, and manage cloud-native applications for the z15 family. Perhaps the biggest talking point with these models is IBM Secure Execution for Linux, a hardware- based security technology that creates isolated Trusted Execution Environments (TEEs) that restrict access to busines-critical or sensitive data, but still allow administrators and developers to perform their jobs. Secure Execution is a way to mitigate insider threats to enterprise data. Basically, Secure Execution provides a KVM-based (Kernel-based Virtual Machine) virtual machine that is fully isolated and protected from the hypervisor with encryption keys that only the IBM Z hardware and firmware have access to. You can, perhaps, think of the z15 Model T02 and LinuxONE III LT2 as the Business Class versions of the z15 Model T01 and LinuxONE III LT1. Security has been a major issue this year with staff working from home seemingly more relaxed about clicking on email links or downloading attachments. This has given bad actors access to their computer and then their corporate network, and then, possibly, their mainframe, using login information taken from keylogging software installed on that home PC. The Ponemon Institute conducted research for IBM Security to produce the annual “Cost of a Data Breach Report 2020”1. They interviewed 3,200 individuals from 17 countries or regions and found 524 breached organizations. From that they found that the average cost of a data breach is $3.86 million. However, the average cost in the USA was $8.64 million. 80 percent of breached organizations stated that customer personally-identifiable information (PII) was compromised during the breach – which could lead to fines from GDPR. Worryingly, the average time to identify and contain a breach was a whopping 280 days. Healthcare was the most expensive industry affected by a breach, costing companies, on average $7.13 million. The report also suggested that security automation – where organizations used technologies such as AI, analytics, and automated orchestration – was the most effective technique to mitigate data breach costs. Their figures showed an average total cost reduction by using security automation of $3.58 million. Most years, we’d be talking about IBM mergers and acquisitions. This year it has acquired Spanugo (a provider of cloud cybersecurity posture management solutions), and WDG Automation to add to its AI-based enterprise automation. Perhaps the biggest news is its plans to split up. It has said that in 2021, it will be spinning off some of its lower-margin lines of business into a new company and focusing on higher-margin cloud services. The new spin-off is currently being referred to as ‘NewCo’. The idea is that IBM “will focus on its open hybrid cloud platform, which represents a $1 trillion market opportunity”, and NewCo “will immediately be the world’s leading managed infrastructure services provider”. NewCo will include IBM Global Technology Services’ existing managed infrastructure clients. BMC Software has managed to acquire Compuware (perhaps, best known for its DevOps products), and RSM Partners (best known for their security work). Syncsort changed its name to Precisely. And Rocket Software acquired both ConnectiQ (best known for mainframe Robotic Process Automation (RPA)) and WebConnect (known for mainframe terminal emulation software) from UK-based ActiveOps.. 4 © Arcati Ltd, 2021 ArcatiArcati MainframeMainframe YearbookYearbook 20072021 Mainframe Strategy Apart from all the words associated with the lockdown, there haven’t been many associated with IT.

  • In-Game Communications Analysis As an Indicator of Recognition Primed Decision Making in Elite Australian Rules Football Umpires
    Neville, T.J., Salmon, P.M. Look Who’s Talking - In-game Communications Analysis as an Indicator of Recognition Primed Decision Making in Elite Australian Rules Football Umpires Look Who’s Talking - In-game Communications Analysis as an Indicator of Recognition Primed Decision Making in Elite Australian Rules Football Umpires Timothy J. NEVILLEa,b, Paul M. SALMONa a University of the Sunshine Coast Accident Research, The University of the Sunshine Coast, Sippy Downs, Queensland, Australia b Joint and Operations Analysis Division, The Defence Science and Technology Organisation, Canberra, Australia ABSTRACT Officials in sport operate in a naturalistic environment making rapid decisions under stress. In sport, decision making research has identified consistent results between the three different ‘variations’ of the Recognition Primed Decision (RPD) model. This paper presents the findings from a study applying the RPD model to the decision making of Australian Rules Football (AFL) umpires. Method: Audible communication instances from AFL Field umpires were transcribed. The data was coded into ‘decision moments’; each decision moment was analysed to identify if the decision conformed to one of the three RPD model variations. Results: Within the 6025 communication instances 887 decision moments were identified. 78% of the decision moments were classified as Variation 1, 18% as Variation 2 and 3.5 % as Variation 3. Discussion: Decision making in AFL umpires is characterized by a similar RPD breakdown as decision making by players in sport.

There are 405,535 employees and 798,152 stockholders at year-end. Organization IBM President John F. Akers succeeds John R. Opel as chief executive officer, effective February 1. Mr. Akers also is to head the Corporate Management Board and serve as chairman of its Policy Committee and Business Operations Committee. PC dealer sales, support and operations are transferred from the Entry Systems Division (ESD) to the National Distribution Division, while the marketing function for IBM’s Personal Computer continues to be an ESD responsibility. IBM announces in September a reorganization of its U.S. marketing operations. Under the realignment, to take effect on Jan. 1, 1986, the National Accounts Division, which markets IBM products to the company’s largest customers, and the National Marketing Division, which serves primarily medium-sized and small customer accounts, are reorganized into two geographic marketing divisions: The North-Central Marketing Division and the South-West Marketing Division. The National Distribution Division, which directs IBM’s marketing efforts through Product Centers, value-added remarketers, and authorized dealers, is to merge its distribution channels, personal computer dealer operations and systems supplies field sales forces into a single sales organization. The National Service Division is to realign its field service operations to be symmetrical with the new marketing organizations.

    Front cover Using IBM System z As the Foundation for Your Information Management Architecture Redguides for Business Leaders Alex Louwe Kooijmans Willie Favero Fabricio Pimentel Information management challenges Strengths of IBM System z for information management Exploring the IBM Smart Analytics Optimizer for DB2 for z/OS V1.1 Executive overview Many companies have built data warehouses (DWs) and have embraced business intelligence (BI) and analytics solutions. Even as companies have accumulated huge amounts of data, however, it remains difficult to provide trusted information at the right time and in the right place. The amount of data collected and available throughout the enterprise continues to grow even as the complexity and urgency of receiving meaningful information continues to increase. Producing meaningful and trusted information when it is needed can only be achieved by having an adequate information architecture in place and a powerful underlying infrastructure. The amounts of data to mine, cleanse, and integrate are becoming so large that increasingly the infrastructure is becoming the bottleneck. This results in low refresh rates of the data in the data warehouse and in not having the information available in time where it is needed. And even before information can become available in a BI dashboard or a report, many preceding steps must take place: the collection of raw data; integration of data from multiple data stores, business units or geographies; transformation of data from one format to another; cubing data into data cubes; and finally, loading changes to data in the data warehouse. Combining the complexity of the information requirements, the growing amounts of data, and multiple layers of the information architecture requires an extremely powerful infrastructure.

  • Arxiv:2011.01874V1 [Cs.SI] 8 Oct 2020 Extracting the True User Intent from the Noise Is a Daunting Task
    Contextualisation of eCommerce Users Hassan Elhabbak Benoît Descamps Digital Advanced Analytics Digital Advanced Analytics Adidas International,Amsterdam Adidas International,Amsterdam Netherlands, 1101 BA Netherlands, 1101 BA [email protected] [email protected] Elisabeth Fischer Data Science Chair Julius-Maximilians Universität W’urzburg´ Germany, 91074 [email protected] Sakis Athanasiadis Digital Advanced Analytics Adidas International,Amsterdam Netherlands, 1101 BA [email protected] Abstract A scaleable modelling framework for the consumer intent within the setting of e-Commerce is presented. The methodology applies contextualisation through embeddings borrowed from Natural Language Processing. By considering the user session journeys throughough the pages of a website as documents, we capture contextual relationships between pages, as well as the topics of the of user visits. Finally, we empirically study the consistency and the stability of the presented framework. 1 Introduction Millions of users interact daily on global e-Commerce websites yielding billions of data points. Understanding the users’ intent is a key step towards personalising their consumer journeys. However, arXiv:2011.01874v1 [cs.SI] 8 Oct 2020 extracting the true user intent from the noise is a daunting task. Every single user interaction is unfortunately not necessarily representative of a user’s visit. Click interactions are known to be noisy and highly biased as shown in the case of recommendation Aslanyan & Porwal (2018). Despite the above, these interactions have been found to be valuable sources of implicit feedback Joachims et al. (2007). In this work, we take a few steps to address this challenge, aiming to provide a definition of consumer intent within an e-Commerce setting.
