Key Factor

Aberrant cost–benefit decision making is a key factor related to individual differences in the expression of substance use disorders (SUDs). Previous research highlights how delay-cost sensitivity affects variability in SUDs; however, other forms of cost–benefit decision making—effort-based choice—have received less attention. We administered the Effort Expenditure for Rewards Task (EEfRT) in an SUD-enriched community sample ( N = 80). Individuals with more severe SUDs were less likely to use information about expected value when deciding between high-effort, high-reward and low-effort, low-reward options. Furthermore, individuals whose severity of use was primarily related to avoiding aversive affective states and individuals with heightened sensitivity to delay costs during intertemporal decision making were the least sensitive to expected value signals when making decisions to engage in effortful behavior. Together, these findings suggest that individuals with more severe SUDs have difficulty integrating multiple decision variables to guide behavior during effort-based decision making.

AbstractChronic stress can impact decision-making and lead to a preference for immediate rewards rather than long-term payoffs. Factors that may mitigate these effects of chronic stress on decision-making are under-explored. Here we used a mouse model to investigate the changes in decision-making caused by the experience of chronic stress and the role of social interaction in attenuating these changes. To test decision-making, mice were trained to perform a Cost-Benefit Conflict (CBC) task on a T-maze, in which they could choose between a high-reward, high-risk alternative and a low-reward, low-risk alternative. Mice were either housed in groups or alone throughout the experiment. Both groups of mice underwent a seven-day period of repeated immobilisation to induce chronic stress. Stress levels were confirmed using behavioural (open field test) and physiological (urine corticosterone ELISA) measures. We found a significant increase in frequency of high-risk decisions after exposure to chronic stress among both socially- and individually-housed mice. Crucially, socially-housed mice showed a significantly smaller increase in high-risk decision-making compared to singly-housed mice. These findings suggest that although chronic stress leads to an increase in high-risk decision-making in mice, access to social interaction may mitigate this stress effect.

Sustainable development is a priority for the future of our society. Sustainable development is of particular importance to the Architecture, Engineering, and Construction (AEC) industry, both for new buildings and for the renovation of existing buildings. Great potential for sustainable development lies in the renovation of existing office buildings. This paper introduces a new framework for identifying the best set of renovation strategies for existing office buildings. The framework applies selected green building rating system criteria and cost-effective sustainable renovation solutions based on cost-benefit analysis (CBA), and thus provides a novelty in decision-making support for the sustainable renovation of office buildings at an early-stage. The framework covers all necessary steps and activities including data collection, determination of the required level of renovation, selection of the green building rating system, identification of impact categories and criteria, and final evaluation and decision-making using CBA. The framework can be used in conjunction with different systems and according to different regional characteristics. The applicability of the addressing procedure is shown through a case study of a comprehensive renovation of an office building in the city of Maribor.

Offshore vessels (OVs) often require precise station-keeping and some vessels, for example, vessels involved in geotechnical drilling, generally use Spread Mooring (SM) or Dynamic Positioning (DP) systems. Most of these vessels are equipped with both systems to cover all ranges of water depths. However, determining which system to use for a particular operational scenario depends on many factors and requires significant balancing in terms of cost-benefit. Therefore, this research aims to develop a platform that will determine the cost factors for both the SM and DP station-keeping systems. Operational information and cost data are collected for several field operations, and Artificial Neural Networks (ANN) are trained using those data samples. After that, the trained ANN is used to predict the components of cost for any given environmental situation, fieldwork duration and water depth. Later, the total cost is investigated against water depth for both DP and SM systems to determine the most cost-effective option. The results are validated using two operational scenarios for a specific geotechnical vessel. This decision-making algorithm can be further developed by adding up more operational data for various vessels and can be applied in the development of sustainable decision-making business models for OVs operators.

Cost-Benefit Analysis (CBA) has been serving as an important tool for decision making with regard to the development projects involving large investments. The Social Cost-Benefit Analysis (SCBA) is an extension of the CBA to certain social impacts, which hitherto were not measured. As the impacts of development projects on ecology and environment assumed importance, measuring the corresponding costs and benefits also began to assume significance. With the advancement in economic valuation techniques over time, measurement could be done and the framework of SCBA has been extended to incorporate the same. Moreover, unlike the CBAs, which do not account for the distributional aspects, the SCBA can potentially account for these. This paper presents a case study of extending the SCBA framework to include social and environmental impacts of a large water resource development project in India. It emphasises the distribution of project benefits and costs over stakeholders, spatial locations and time horizons so as to demonstrate the utility of extended SCBA in project decision making. It is observed that both the numeraire measure i.e. cost-benefit ratio, as well as the distributional analysis present a favourable case for the project.

As communication teachers attempting to bridge the gap between school and industry, we need to give students a true understanding of what it means to be a professional. We may be spending too much time trying to get them to write and speak like professionals without also imbuing them with sufficient understanding of their responsibilities to behave as professionals. Students need to be practiced in the communication and decision-making situations they will encounter in their workplaces. These decisions involve ethical reasoning as well as technical problem solving. Teaching students to appreciate the consequences of their recommendations, through the use of fault-trees and cost/benefit analyses in realistic simulations, effectively bridges the gap between the classroom and boardroom. A sample situation is explained and analyzed for its use in any technical communications class.

Der wachsende Bedarf an Wandlungsfähigkeit führt zu einer höheren Frequenz in der Umplanung von Montagesystemen und erfordert eine kontinuierliche Überprüfung und Anpassung des Automatisierungsgrades. Um auch die komplexen Umgebungsbedingungen abzubilden, sollen nicht-monetäre Faktoren in den Entscheidungsprozess eingebunden werden. Um die Entscheidung zu unterstützen, stellt dieser Beitrag ein Tool zur Identifizierung und Bewertung von Automatisierungsszenarien mittels einer Nutzwert-Aufwand-Analyse vor.   The increasing need for adaptability in assembly leads to a higher planning frequency of the system and requires continuous checks and adaptations of the appropriate level of automation. To account for the complex environmental conditions, non-monetary factors are included in the decision-making process. This paper presents a decision support tool to identify and evaluate automation scenarios by means of cost and benefit evaluation.

This study analyzed the evidence available in the literature concerning the effectiveness of different active cutaneous warming systems to prevent intraoperative hypothermia. This is a systematic review with primary studies found in the following databases: CINAHL, EMBASE, Cochrane Register of Controlled Trials and Medline. The sample comprised 23 randomized controlled trials. There is evidence in the literature indicating that the circulating water garment system is the most effective in maintaining patient body temperature. These results can support nurses in the decision-making process concerning the implementation of effective measures to maintain normothermia, though the decision of health services concerning which system to choose should also take into account its cost-benefit status given the cost related to the acquisition of such systems.
