Project portfolio selection based on multi-project synergy

<p style='text-indent:20px;'>To date, the selection of a project portfolio that maximises the decision-making outcome remains essential. However, existing research on project synergy has mainly focused on two projects, while there are multiple projects in some cases. Two kinds of synergies among multiple projects are proposed. First, multiple projects must be selected together, in order to produce synergy. Second, some projects depend on synergy with other projects, leading to a synergetic increase in performance. Furthermore, we present strategic synergy, with benefits, resources, and technology, which is quantified for a procurement project concerning a COVID-19 pandemic recovery plan. A design structure matrix is used to describe the technology diffusion among the projects. Then, strategic alignment is utilised to measure the strategic contribution of projects. Next, a portfolio selection model considering uncertainty is established, based on the strategic utility. Finally, our results indicate that selecting projects considering multi-project synergy is more advantageous.</p>

International University Network Internet Project of Integrated Engineering Education

The transfer of educational technologies of the OECD countries for higher technical education in the CIS requires significant financial and material resources. It is advisable to unite pedagogical teams and the laboratory base of universities that train specialists in related specialties using the Internet. The international scientific and educational network Internet project “Synergy” has been implemented with the support of the concern “Festo” (Germany). The universities directly involved in the regular educational activities of the project are NIU Moscow Power Engineering Institute, Peter the Great St. Petersburg Polytechnic University, the Baltic State Technical University “VOENMECH” named after D.F. Ustinova, Omsk State Technical University and Karaganda State Technical University. The laboratories of the project participants are equipped with modern training stands and multimedia tools for conducting on-line courses and laboratory work in the remote access mode produced by the leading domestic and foreign companies including world leaders in the field of automation and robotics Festo, Siemens, Mitsubishi Auto Electrician.Regular online training has been organized with the use of exchange, composite and embedded module courses. The experience gained in the process of project implementation became the basis for the development of a new interdisciplinary program for the specialized magistracy as “Robotics. Control systems” for the Kazakhstan industry. The international university network project “Synergy” can become the basis for the practical implementation of the principles of the Bologna process, taking into account the specifics of the CIS countries.

Association between suicidal ideation and suicide: meta-analyses of odds ratios, sensitivity, specificity and positive predictive value

BackgroundThe expression of suicidal ideation is considered to be an important warning sign for suicide. However, the predictive properties of suicidal ideation as a test of later suicide are unclear.AimsTo assess the strength of the association between suicidal ideation and later suicide measured by odds ratio (OR), sensitivity, specificity and positive predictive value (PPV).MethodWe located English-language studies indexed in PubMed that reported the expression or non-expression of suicidal ideation among people who later died by suicide or did not. A random effects meta-analysis was used to assess the pooled OR, sensitivity, specificity and PPV of suicidal ideation for later suicide among groups of people from psychiatric and non-psychiatric settings.ResultsThere was a moderately strong but highly heterogeneous association between suicidal ideation and later suicide (n = 71, OR = 3.41, 95% CI 2.59–4.49, 95% prediction interval 0.42–28.1, I2 = 89.4, Q-value = 661, d.f.(Q) = 70, P ≤0.001). Studies conducted in primary care and other non-psychiatric settings had similar pooled odds to studies of current and former psychiatric patients (OR = 3.86 v. OR = 3.23, P = 0.7). The pooled sensitivity of suicidal ideation for later suicide was 41% (95% CI 35–48) and the pooled specificity was 86% (95% CI 76–92), with high between-study heterogeneity. Studies of suicidal ideation expressed by current and former psychiatric patients had a significantly higher pooled sensitivity (46% v. 22%) and lower pooled specificity (81% v. 96%) than studies conducted in non-psychiatric settings. The PPV among non-psychiatric cohorts (0.3%, 95% CI 0.1%–0.5%) was significantly lower (Q-value = 35.6, P < 0.001) than among psychiatric samples (3.9%, 95% CI 2.2–6.6).ConclusionsEstimates of the extent of the association between suicidal ideation and later suicide are limited by unexplained between-study heterogeneity. The utility of suicidal ideation as a test for later suicide is limited by a modest sensitivity and low PPV.Declaration interestM.M.L. and C.J.R. have provided expert evidence in civil, criminal and coronial matters.
