Unpacking the effects of adverse regulatory events: evidence from pharmaceutical relabeling

We provide causal evidence that regulation induced product shocks significantly impact aggregate demand and firm performance in pharmaceutical markets. Event study results suggest an average loss between $569 million and $882 million. Affected products lose, on average, $186 million over their remai...(Read Full Abstract)

A mathematical model for predicting length of postoperative intensive care requirement following cardiac surgery in an Indian hospital

Intensive care unit (ICU) is a critical resource in a hospital, especially in developing countries such as India. The length of ICU stay after a cardiac surgery is an important variable for effective use of this critical resource. In this context, a predictive model can help a hospital to make optim...(Read Full Abstract)

A new model for the asymmetric vehicle routing problem with simultaneous pickup and deliveries

The purpose of this note is to serve as a revision to the article by Al-Salamah (2016). We offer two modifications to the above paper. First, we demonstrate that the inventory computations by Al-Salamah (2016) are not entirely consistent with the process mentioned, as they do not account for the def...(Read Full Abstract)

A study on understanding the factors of non-compliance in motorized two-wheeler helmet use in India: a review of literature

Injuries related to road traffic are the major causes of death among people in the age bracket of 15–29 years (World Health Organization 2015). In many developing countries, motorized two-wheelers are the dominant means of transport and contribute to a more significant proportion of road fatalities....(Read Full Abstract)

A time-use perspective of out-of-home activity participation by older people in Hong Kong

Promoting active ageing has emerged as a key objective of urban planning and policymaking globally. Our study aims to provide new insights from a time-use perspective. In this paper, we use Hong Kong as a case study to investigate how people aged 60 and older allocate their time in various out-of-ho...(Read Full Abstract)

AGV or Lift-AGV? Performance trade-offs and design insights for container terminals with robotized transport vehicle technology

New container terminals are embracing robotized transport vehicles such as lift-automated guided vehicles (LAGVs) and automated guided vehicles (AGVs) to enhance the terminal throughput capacity. Although LAGVs have a high container handling time, they require less coordination with other terminal e...(Read Full Abstract)

Bridging the gap between probabilistic and fuzzy entropy

The real-world decision making often involves a comparison of uncertain systems or alternatives based on fuzzy evaluations. The concept of fuzzy entropy is quite useful in such situations. However, fuzzy entropy and the conventional probabilistic entropy differ in their semantics. This article criti...(Read Full Abstract)
