Measuring total performance of prospective alternatives in decision making (DM) needs aggregation of their noncomparable properties which often have different scales of measure. In order to address this, scale transformations and normalization are applied, but problems of validation of such additive models and interpretation of the physical sense of the result arise. In this paper, a multiplicative performance aggregation of properties' values is suggested for DM. Application of the approach enables consistent and unambiguous ranking of the alternatives allowing values of all their properties of interest. A realistic example of DM related to audit activity planning is considered where several competing control areas should be selected into an audit plan. Beyond audit planning, the approach is generalizable to other DM problems in corporate management and governance where one needs to rank alternatives compared in multiple dimensions.

Environmental conditions can have spatially complex effects on the dynamics of marine fish stocks that change across life-history stages. Yet the potential for non-stationary environmental effects across multiple dimensions, e.g. space and ontogeny, are rarely considered. In this study, we examined the evidence for spatial and ontogenetic non-stationary temperature effects on Pacific hake Merluccius productus biomass along the west coast of North America. Specifically, we used Bayesian additive models to estimate the effects of temperature on Pacific hake biomass distribution and whether the effects change across space or life-history stage. We found latitudinal differences in the effects of temperature on mature Pacific hake distribution (i.e. age 3 and older); warmer than average subsurface temperatures were associated with higher biomass north of Vancouver Island, but lower biomass offshore of Washington and southern Vancouver Island. In contrast, immature Pacific hake distribution (i.e. age 2) was better explained by a nonlinear temperature effect; cooler than average temperatures were associated with higher biomass coastwide. Together, our results suggest that Pacific hake distribution is driven by interactions between age composition and environmental conditions and highlight the importance of accounting for varying environmental effects across multiple dimensions.

Objective: To promote a discussion on the benefits and challenges of the process of implementing mechanisms and good corporate governance practices in a multifamily company. Method: the case was based on real problems of a privately held multifamily organization and fictitious narratives were developed for its construction. Originality/relevance: Multifamily companies potentialize the existence of conflicts between the main ones due to the plurality of partners regarding corporate management and control. In this teaching case, some of these dilemmas were presented and how corporate governance could avoid, mitigate or remedy them in order to find adequate alignment between family members. Results: Conflicts of interest and information asymmetries indicated the need for new solutions for business continuity. Among these solutions, there was the possibility of implementing mechanisms and good corporate governance practices. Theoretical/methodological contributions: It is expected that the student develops an understanding of the need to consider inherent gains and losses in decision making and the particularities of the organization, such as shareholder composition, maturity of the organization and protection of capital and property.

Background. There is growing interest in multicriteria decision analysis (MCDA) for shared decision making (SDM). A distinguishing feature is that a preferred treatment should extend years of life and/or improve health-related quality of life (HRQL). Additive MCDA models are inadequate for the task. A plethora of MCDA models exist, each claiming that it can correctly solve real-world problems. However, most were developed in nonhealth fields and rely on additive models. This makes the problem of choosing an MCDA model as an aid for SDM a challenging and urgent one. Methods. A published 2017 MCDA of a hypothetical prostate cancer patient is used as a case in point of how not to do and how to do MCDA for SDM. We critically review it and analyze it using several additive linear MCDA models with years of life and HRQL as attributes and the linear quality-adjusted life-year (QALY) model. The following simple reasonableness test is presented for applicability of a method as an aid for SDM: Can a treatment that causes premature death trump a treatment that causes acceptable adverse effects? Results. Additive MCDA models and the linear QALY recommend significantly different alternatives. Additive MCDA models fail the proposed reasonableness test; the linear QALY model passes. Conclusions. MCDA possesses a strong craft element in addition to its technical aspects. MCDA practitioners and clinicians need to understand model limitations to choose models appropriate to the context. Additive MCDA models are inadequate for life-critical SDM. We advocate QALY models with additional research for increased realism as a tool for SDM.

The results of recent studies of the processes of domestic enterprises prove the need to focus on decision-making in conditions of high uncertainty, institutional restrictions and interests of interested groups influencing the adoption of the strategically important decisions. The authors propose to consider the strategic decision as a result of collective choice as to means and actions that meet the principles of corporate management and the interests of the main groups – participants of corporate relations to achieve strategic goals. From such positions, the types of strategic decisions are grouped according to the following signs: purposefulness and content of the issues to make up decisions; organizational model of decision-making; completeness of knowledge and ways of their application by decision-makers. The results of a comprehensive analysis of the state and prospects of enterprise development are presented in order to study the peculiarities of strategic decision-making at the enterprises of the machine-building industry according to their allocated signs. The technology of comprehensive analysis of the strategic decisions of enterprises consists of stages and an evaluation-analytical instrumentarium – indicators and criteria, methods of evaluation, analysis and interpretation of results. The built up system of indicators corresponds to the functional spheres of the enterprise according to the criteria of financial-economic stability, production efficiency, effectiveness of marketing activities and efficiency of use of staff. The defined criteria and indicators act as rational basis for the development, comparison and choice of alternatives to development, substantiation of strategic decisions of enterprise. As a result of the carried out cluster analysis according to the computed generalized performance indicators of 18 machine-building enterprises of Kharkiv region, clusters of enterprises, development strategies and identical strategic solutions for each cluster of enterprises are allocated as follows: technical and technological development (product renewal, expansion of sale markets and search for new ones, restructuring of production capacities) and ensuring the sustainability of the financial-economic condition (through consolidation and movement of capital, saving, costs reduction, search for additional sources of income, recovery of assets).

Aim: Creation of a single indicator of access to medicines. Methods: Data collection was performed with individuals who obtained their medication from either public and/or private pharmacies. A Likert scale was used to measure the importance and satisfaction in relation to various access dimensions. Results: A total of 580 individuals were interviewed. Overall, participants attributed very similar importance scores to the dimensions of access to medicines. The results of the mean score of each dimension showed a statistically significant difference according to the type of pharmacy that the participant visited. Conclusion: This developed indicator will enable a review of access to medicines, making comparisons possible as well as improving decision making about public policies in the field of Pharmaceutical Services.

e17053 Background: Cancer patients’ potential for severe financial toxicity (FT) is well-established, however there is limited data on the magnitude of this challenge associated with treatment of localized prostate cancer (PC). The extent to which men consider potential financial implications prior to selection of a treatment strategy remains poorly understood. Methods: Between 5/2020-10/2020, 1233 insured PC patients treated at a comprehensive cancer center completed a one-time FT survey which included the COmprehensive Score for financial Toxicity (COST) instrument, impressions of PC costs and financial coping strategies. Inclusion criteria was localized disease and treatment with either radical prostatectomy (RP) or definitive radiotherapy (RT) in the previous 4-26 months (mo) or at least 6mo of active surveillance (AS) prior to survey. To assess possible temporal differences in FT, responses were grouped into 6, 12, 18 and 24 months after treatment start, and we plotted COST against time, using generalized additive models to allow for non-linearity. Results: Overall, 988 men were eligible for analysis: 347 (35%) underwent RP, 384 (39%) underwent RT, and 257 (26%) were on AS. The median age at survey completion was 67 years (quartiles 62, 72). Men were predominantly white (89%), English-speakers (99%) and married (84%). The median (quartiles) COST score for all patients was 33 (26, 38) with possible range of 0-44 with lower scores indicating greater FT; median values were identical with similar quartiles (+/- 1 point) when stratified by treatment type. There were no significant changes in median COST between men surveyed at the four time points for any treatment subgroup. In total, 66 men (7.1%) reported spending > 20% of annual income on treatment and 10% felt that PC has created at least somewhat of a financial hardship for their family. Top drivers of burdensome cost included medical bills (37%) and transportation costs (21%). Most (83%) reported giving little or no consideration to possible costs prior to making a PC treatment decision, yet the majority (77%) felt that out of pocket costs should be communicated to a patient prior to decision making. Most believed patients should definitely (46%) or possibly (33%) have the opportunity to discuss financial concerns with the radiation oncologist or urologist. Conclusions: Our study is the first reported use of the COST instrument to assess subjective financial distress in localized PC patients. Our results demonstrate that the overall degree of FT in this cohort of insured patients treated at a specialized cancer center is low. While potential financial burden does not strongly influence treatment decision making in this cohort, most want this information and an opportunity to discuss financial concerns with their oncologist. Next steps include identification of predictors for high FT risk and extension of our survey to hospital systems with differing demographic profiles.
