Background Eritrean gross national income of Int$610 per capita is lower than the average for Africa (Int$1620) and considerably lower than the global average (Int$6977). It is therefore imperative that the country’s resources, including those specifically allocated to the health sector, are put to optimal use. The…

Background The Palestinian government has been under increasing pressure to improve provision of health services while seeking to effectively employ its scare resources. Governmental hospitals remain the leading costly units as they consume about 60 % of governmental health budget. A clearer understanding of the…

Technical efficiency indices (TEIs) can be estimated using the traditional stochastic frontier analysis approach, which yields relative indices that do not allow self-interpretations. In this paper, we introduce a single-step estimation procedure for TEIs that eliminates the need to identify best practices and avoids…

In this article, the concepts of technical efficiency, efficiency, effectiveness and productivity are illustrated. It is discussed that when firms are not homogenous, the situation is the same as when each factor has a different unit of measurement from one firm to another, and therefore, no meaningful discrimination…

'Dao-Zhi Zeng'] The use of elasticities of substitution between inputs is a standard method for addressing the effect of a change in the mix of inputs used for production from a technical or cost standpoint. Most estimation methods use parametric production or cost functions or frontiers to estimate these elasticities.…

Business incubators can play a major role in helping to turn a business idea into a technology-based organization that is economically efficient. However, there is a shortage in the literature regarding the efficiency evaluation and productivity evolution of the new technology-based firms (NTBFs) in the incubation…

DEA was first used to measure efficiency by Charnes et al. (), building on Farrell’s () productive efficiency ideas. The basic model of DEA is fractional programming (FP), which is difficult to compute. Later, the FP model was modified into linear programming (LP), making it easy to calculate efficiency values. DEA LP…

As human lifespan increases and the need for elderly care grows, the demand for healthcare services and its associated costs have surged, causing a decline in the operational efficiency of universal healthcare. This has created an imbalance in medical services across different regions, posing a long-standing challenge…

The term efficient has gained great popularity in the chemical literature, despite the lack of an applicable and relatable definition. In this perspective, a chemical definition of efficiency is discussed building on the concept of non-wasteful resource usage. It is proposed than an efficient method, synthesis or…

Background Hospitals are the most costly and important components of any health care system, so it is important to know their economic values, pay attention to their efficiency and consider factors affecting them. Objective The aim of this study was to assess the technical scale and economic efficiency of hospitals in…

In this study, we conducted the conceptual design of a system aimed at delivering constant energy supply for a decarbonised urban mobility setting. To this scope, we designed two systems based on battery electrical vehicles (BEV) and fuel cell electric vehicles (FCEV). The supply is primarily provided by renewable…

Currently, there is quite a strange situation in the knowledge "market". A great number of publications consider efficiency as the "old good friend". At the same time, without the validation of the developed criterion, a reader is invited to use one or the other indicator as efficiency indicator. It resembles the…

Unlike the Carnot heat engine efficiency published in 1824, an isothermal efficiency derived from thermodynamics and information theory can be applied to biological systems. The original approach by Pierce and Cutler in 1959 to derive the isothermal efficiency equation came from Shannon’s channel capacity of 1949 and…

Biological processes underpin centralized wastewater treatment but are difficult to deploy at small scale. Thermomechanical and thermochemical approaches could enable household-level sanitation, yet their economic and environmental potential remains unclear. We assessed two prototype household reinvented toilets…

A strategy for incorporating higher-frequency determinants of inefficiency into the stochastic frontier models with production function indicators compiled at lower frequencies is proposed. Furthermore, the problem with positive skewness in stochastic frontier models is resolved by postulating a logistic function for…

Continuous manufacturing processes offer significant advantages over batch processes, including easier scalability, reduced costs, lower raw material and solvent consumption, and improved energy efficiency. A robust techno-economic assessment is therefore essential to evaluate and facilitate the adoption of such…

The in vivo mechanical efficiency of muscles has often been estimated during sub-maximal cycling. In this approach, it has implicitly been assumed that the average amount of positive mechanical muscle power equals the average mechanical power output, i.e., that no power is dissipated by muscles. Here, we investigated…

Biotechnological production of recombinant molecules relies heavily on fed-batch processes. However, as the cells’ growth, substrate uptake, and production kinetics are often unclear, the fed-batches are frequently operated under sub-optimal conditions. Process design is based on simple feed profiles (e.g., constant or…

Although definitions of technology exist to explain the patterns of technological innovations, there is no general definition that explain the role of technology for humans and other animal species in environment. The goal of this study is to suggest a new concept of technology with a systemic-purposeful perspective…

Movement is integral to animal life, and most animal movement is actuated by the same engine: skeletal muscle. Muscle input is typically mediated by skeletal elements, resulting in musculoskeletal systems that are “geared”: at any instant, the muscle force and velocity are related to the output force and velocity only…
