The Best-or-Worst and the Postdoc problems
We consider two variants of the secretary problem, the\emph{ Best-or-Worst}
and the \emph{Postdoc} problems, which are closely related. First, we prove
that both variants, in their standard form with binary payoff 1 or 0, share the
same optimal stopping rule. We also consider additional cost/perquisites
depending on the number of interviewed candidates. In these situations the
optimal strategies are very different. Finally, we also focus on the
Best-or-Worst variant with different payments depending on whether the selected
candidate is the best or the worst

Well rounded Postdoctoral Researchers with initiative, who are not always âtied to the benchâ are more successful academically
This article reports the development, application and results of a baseline
investigation of contract research staff in 2007 in the Medical School at the
University of Sheffield which was carried out in order to develop a specifically
tailored training and career development programme and allow for future impact
evaluation of the scheme. Postdoctoral researchers reported on their perceived skill
levels, academic achievements, career motivations and the current research
environment. Results indicated that transferable skills related to communication and
awareness of the process of research (i.e. the process of acquisition of funding,
commercialisation of research outputs) were lacking. Furthermore, these skills were
associated with higher publication outputs, and improved with mobility between
institutions at postdoctoral level. This paper also describes how the findings from the
baseline evaluation were used to develop a programme to address the lower ranking
skills and evaluate the impact of the programme
Novel Artificial Human Optimization Field Algorithms - The Beginning
New Artificial Human Optimization (AHO) Field Algorithms can be created from
scratch or by adding the concept of Artificial Humans into other existing
Optimization Algorithms. Particle Swarm Optimization (PSO) has been very
popular for solving complex optimization problems due to its simplicity. In
this work, new Artificial Human Optimization Field Algorithms are created by
modifying existing PSO algorithms with AHO Field Concepts. These Hybrid PSO
Algorithms comes under PSO Field as well as AHO Field. There are Hybrid PSO
research articles based on Human Behavior, Human Cognition and Human Thinking
etc. But there are no Hybrid PSO articles which based on concepts like Human
Disease, Human Kindness and Human Relaxation. This paper proposes new AHO Field
algorithms based on these research gaps. Some existing Hybrid PSO algorithms
are given a new name in this work so that it will be easy for future AHO
researchers to find these novel Artificial Human Optimization Field Algorithms.
A total of 6 Artificial Human Optimization Field algorithms titled "Human
Safety Particle Swarm Optimization (HuSaPSO)", "Human Kindness Particle Swarm
Optimization (HKPSO)", "Human Relaxation Particle Swarm Optimization (HRPSO)",
"Multiple Strategy Human Particle Swarm Optimization (MSHPSO)", "Human Thinking
Particle Swarm Optimization (HTPSO)" and "Human Disease Particle Swarm
Optimization (HDPSO)" are tested by applying these novel algorithms on Ackley,
Beale, Bohachevsky, Booth and Three-Hump Camel Benchmark Functions. Results
obtained are compared with PSO algorithm.Comment: 25 pages, 41 figure
University departments evaluation: a multivariate approach
Aim of the paper is to present a new model, based on multivariate statistic analyses, allowing to express a synthetic judgement on Departments activities by taking into consideration the whole set of indicators describing them both as aggregations of researchers and as University autonomous organs. The model, based on Principal Component Analysis and Cluster Analysis, allows both to explain the determinants of Departments performances, and to classify them into homogeneous groups. The paper shows the results obtained by testing the proposed model on University of Naples âLâOrientaleâ Departments, using data extracted by the 2007 assessment report to the Ministry of University and Research.Evaluation, Departments, Multivariate statistics
Shifting landscapes: from coalface to quick sand? Teaching geography, earth and environmental sciences in UK higher education
In this paper we examine contemporary academic working lives, with particular reference to teaching-only and teaching-focused academics. We argue that intensification in the neoliberal university has significantly shifted the structure of academic careers, while cultural stories about those careers have not changed. We call for academics to re-examine our collective stories about standard academic career paths. Challenging the stories and making visible the ways that they create and multiply disadvantage is a crucial step in expanding the possibilities for academic identities and careers. The paper begins by describing teaching-focused academics within the context of the wider workforce. We then draw on narratives of those in these roles to illustrate the processes that (re)inscribe their marginalisation. We uncover the gendering of the teaching-focused academic labour market. We end the paper by suggesting interventions that all academics can take and support to address the issues we highlight
