Does using tighter constraints in optimization problems lead to longer solving time?5 answersUsing tighter constraints in optimization problems can indeed impact solving time. While classic iterative methods often face longer solving times due to exploring the feasible domain extensively, recent advancements in utilizing neural approximators have shown promise in providing rapid solutions by mapping inputs to nearly optimal feasible solutions without the need for iterations. This approach guarantees hard feasibility through a sequence of steps, eliminating the need for parameter tuning and iterations, thus reducing solving time significantly. Additionally, the proposed method has demonstrated superior performance in terms of computational time, optimality, and feasibility compared to existing approaches, showcasing the efficiency gains achieved by leveraging tighter constraints in optimization problems.
How do time-limited offers impact consumer behavior and decision-making?4 answersTime-limited offers have an impact on consumer behavior and decision-making. Deceptive countdown timers, which indicate a limited-time offer that is not truly limited-time, can increase customers' preference for the discounted product. However, consumers have negative responses towards deceptive timers, perceiving them as manipulative, immoral, and unethical. Contextual factors such as time constraints, price discounts, and product price levels, as well as individual differences like previous online consumption experience, also influence consumer purchase intentions. Time constraints influence purchase intentions, and this effect is moderated by consumers' previous online consumption experience. Consumer perceived value mediates the relationship between time constraints and purchase intentions, and price discounts moderate this effect. Limited-time promotions create higher perceived scarcity and subsequently activate higher perceived competition, leading to higher purchase intention. However, this effect is observed only for consumers from individualistic-masculine societies, not for those from individualistic-feminine societies. Time-limited promotions, particularly time-limited flash sales, are positively related to consumers' impulsive purchase tendency and post-purchase regret. Public self-consciousness influences impulse buying and post-purchase regret, and time pressure affects these relationships. Time restriction can influence consumers' response, and the effects are more pronounced for subjects exposed to collectivistic appeals. Construal level mediates consumers' purchase intention, and message quality moderates this effect.
What are the effects of time pressure on the quality of decisions?5 answersTime pressure has various effects on the quality of decisions. Under high time pressure, decision-makers tend to make more risky choices and have shorter decision times. This is because time pressure can hinder the application of knowledge-based action, leading to a persistence of rule-based action even when it may not be the most effective approach. However, the impact of time pressure on decision quality can depend on factors such as the level of time pressure, the experience of the decision-makers, and the type of decision being made. Individual heterogeneity in coping with time pressure can also affect decision quality, with cognitive ability and intellectual efficiency playing a role in successful decision-making under time pressure. In the context of the IT sector, time pressure can have an adverse effect on decision-making, potentially impacting the quality of cyber security services.
How does time limited buying intention affect the purchase decision?5 answersTime-limited buying intentions have an impact on purchase decisions. Contextual factors such as time constraints, price discounts, and product price levels, as well as individual differences like previous online consumption experience, influence consumer purchase intentions. Time constraints specifically influence consumer purchase intentions, and this effect is moderated by consumers' previous online consumption experience. Additionally, consumer perceived value mediates the relationship between time constraints and purchase intentions, and price discounts moderate this effect. The influence of time pressure on consumer perception is particularly relevant for the design of food packages, as consumers with time constraints have higher intention to purchase scores. Multi-channel marketing and discounts also have a positive effect on purchasing decisions, with attractive discounts and effective multi-channel marketing increasing buying interest and purchasing decisions. In the context of fixed-price group buying, countdowns expressed with a contracted scale increase group-buying participation intentions, with temporal focus mediating this effect.
Why nurses experience time pressure or time constraints?5 answersNurses experience time pressure or time constraints due to various factors. The international health workforce crisis has led to a shortage of nurses, resulting in increased workload and limited time available for patient care. Nurses working in hospital-in-the-home (HITH) settings may face additional stress and time pressure while driving to patients' homes, which can affect their driving behavior and emotions. Nurses often report not having enough time to complete all necessary nursing care tasks, leading to nurse-perceived time pressure. Perceived time pressure can be a major stressor for nurses, affecting their decision-making abilities and overall well-being. Additionally, high workloads and time constraints contribute to nurses' lack of firm commitment to their profession. These findings highlight the need for better support for nurses, including optimizing nurse staffing levels and providing organizational and technical solutions to reduce time pressure in nursing practice.
How do time constraints affect human decision making?5 answersTime constraints have been found to have various effects on human decision-making. When under time constraints, individuals tend to adapt their search processes and perceive their task or performance differently. In the context of strategic decision-making, managers with limited time often struggle to make high-quality decisions that are both original and feasible. The impact of time constraints and emotions on decision-making quality varies across different tasks, with happy managers under high time constraints generating fewer original and feasible strategic ideas, while sad managers under high time constraints making better original strategic choices. Decision-makers are inherently limited by computational resources and time availability, leading them to actively seek methods that limit resource demands and exploit structure within the environment to make fast, high-quality decisions. Humans tend to fall back on learned prior choice patterns when faced with increasing resource limitations. Additionally, time constraints enhance the framing effect, leading to riskier behavior when options are presented as losses compared to gains.
