Abstract:
Mesotheliomas are rare tumours. While the benign type is curable by surgery, the malignant forms are difficult to diagnose and treat with a bad prognosis even with modern multimodality treatment. Herein we report four cases of mesothelioma in Iraqi housewives (3 pleural and one pericardial). The diagnosis and treatment of these cases are discussed with review of literature. The primary pericardial mesothelioma has presented as cardiac tamponade. Such presentation was reported only once before in the literature. The three cases of pleural mesotheliomas represented all types i.e., the localized benign, localized malignant and the diffuse malignant. Although exposure to asbestos is reported in 72 -95% of the malignant varieties; none of our patients had such an exposure.
Succession “Losers”: What Happens to Executives Passed Over for the CEO Job?
By David F. Larcker, Stephen A. Miles, and Brian Tayan
Stanford Closer Look Series
Overview:
Shareholders pay considerable attention to the choice of executive selected as the new CEO whenever a change in leadership takes place. However, without an inside look at the leading candidates to assume the CEO role, it is difficult for shareholders to tell whether the board has made the correct choice. In this Closer Look, we examine CEO succession events among the largest 100 companies over a ten-year period to determine what happens to the executives who were not selected (i.e., the “succession losers”) and how they perform relative to those who were selected (the “succession winners”).
We ask:
• Are the executives selected for the CEO role really better than those passed over?
• What are the implications for understanding the labor market for executive talent?
• Are differences in performance due to operating conditions or quality of available talent?
• Are boards better at identifying CEO talent than other research generally suggests?

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

It is never recommended to apply online redo logs directly since it may inadvertently stop recovery when
recovering the current log. If you apply the online redo logs directly in a graceful case, the graceful switchover will
fail.
2
Previous revisions of the graceful switchover and switchback paper stressed that the production controlfile and the
online redo logs need to be copied to the standby database; however we have found problems with controlfile
transaction count mismatches between data file headers and controlfiles (bug 1034927). Oracle now recommends
creating a create controlfile with noresetlogs option script from the production database and copying the script to
the standby database before switchover occurs. The alter database backup controlfile to trace noresetlogs
command must be executed on the production database instead of the standby database (bug 1034871).
3
If the production database is not Oracle Parallel Server, only the online redo logs are required for startup after
recreating the controlfile; however OPS environments may require additional work. Please refer to Considerations
for OPS section in Appendix D.

Bug 1034927 8.1 RDBMS 8.1 RECOVERY PRODID-5 PORTID-453 ORA-1207
Abstract: DATAFILES FROM STANDBY CAN MAKE PRIMARY CONTROLFILE LOOK LIKE A BACKUP
If the primary controlfile is copied to a standby for a graceful switchover to the standby, ORA-1207 may be signalled
when reading datafile headers. If a datafile backup is taken at the standby and copied to the primary for recovery,
ORA-1207 may be signalled when reading the backup datafile header. This happens when the standby does more
controlfile transactions than the primary. The controlfile transaction count is recorded in the datafile header on
every write. If the counter is greater than the counter in the controlfile then the presumption is that the controlfile
must be a backup. However if the last write to the datafile header was done at the standby this check may fail
because the standby controlfile counter is higher than the primary’s. One work around is to recreate a standby
controlfile from the primary and use it for recovery at the standby just before copying the backups to the primary,
or attempting graceful switch over. Another work around is to do a CREATE CONTROLFILE NORESETLOGS to
make a new primary controlfile. The fix is to eliminate the check for ORA-1207. The checkpoint counters in the
controlfile and datafile headers accomplish the same thing except that they always work right. Note that there are
two checks for 1207 that must be eliminated.
Bug 1034871
Abstract: BACKUP CONTROLFILE TO TRACE OUTPUT IS WRONG IF USING BACKUP/STANDBY
CONTROLFILE
If the currently mounted controlfile is either a backup or a standby controlfile then the script produced by ALTER
DATABASE BACKUP CONTROLFILE TO TRACE will be wrong. In particular, datafiles from read only
tablespaces will be listed in the DATAFILE clause rather than left out and renamed after open. There may be other
problems since the command was not designed to work with a backup controlfile. This problem was noted when
attempting to do a graceful switch to a standby -i.e. with no redo loss and no resetlogs. A CREATE CONTROLFILE
NORESETLOGS command can be used at the standby to allow online logs copied from the primary to be applied
to the standby, and to open the standby without RESETLOGS. However the BACKUP CONTROLFILE TO
TRACE command to construct the script must be executed at the primary not the standby. If the read only datafiles
are included in the DATAFILE clause everything will appear to work fine. The read only tablespaces will be
available and can be made read write. However if they are left read only and their is a subsequent resetlogs (maybe
years later) the read only tablespaces will no longer be accessible.
