In dynamic production environments, positive business outcomes often require pursuing high quality, shorter throughput time, and low cost simultaneously. This research tries to track the timing effect of having undetected defects continue to progress through the supply chain. The purpose is to demonstrate the influence of throughput time on quality variance amplification and the effect of quality loss on manufacturing performance. A time series model is developed, and numerical analyses are conducted to understand how various parameters affect the quality variance fluctuation and quality loss amplification phenomena. The results show that the variance in quality increases as materials move down a supply chain, away from a supplier. In addition, the quality loss experienced by a manufacturer is greater than that faced by a supplier. Finally, both quality variability and quality loss amplification phenomena are larger when throughput time is longer.

The Individual

In this commentary, we discuss the state of affairs concerning the clinical care of females with Turner syndrome (TS) in Germany. TS is a rare disease and new international guidelines describe an appropriate setup for optimal clinical care. Several countries have implemented a program with centralized adult Turner syndrome clinics, which are now found in France, Denmark, the Netherlands, Sweden, parts of England and possibly other countries, but hitherto not in Germany. Such an approach should ensure the availability of high quality multi-disciplinary care for all women with TS to be treated and to detect all the conditions that have been associated with TS, which typically appear at odd times during the lifetime of a female with TS. Care should be offered at no added cost for the patient, and treatment with relevant drugs should be available at reasonable cost for the individual patient. Currently, it is quite problematic that many female sex hormone preparations are not available at low cost in a number of countries. Additional problems include supply chain issue which lead to patients not being able to buy their usual drug for a certain period of time. We think it is timely that countries improve the care for individuals with rare conditions, such as TS.

High Quality

The use of low air quality networks has been increasing in recent years to study urban pollution dynamics. Here we show the evaluation of the operational Aburrá Valley’s low-cost network against the official monitoring network. The results show that the PM2.5 low-cost measurements are very close to those observed by the official network. Additionally, the low-cost allows a higher spatial representation of the concentrations across the valley. We integrate low-cost observations with the chemical transport model Long Term Ozone Simulation-European Operational Smog (LOTOS-EUROS) using data assimilation. Two different configurations of the low-cost network were assimilated: using the whole low-cost network (255 sensors), and a high-quality selection using just the sensors with a correlation factor greater than 0.8 with respect to the official network (115 sensors). The official stations were also assimilated to compare the more dense low-cost network’s impact on the model performance. Both simulations assimilating the low-cost model outperform the model without assimilation and assimilating the official network. The capability to issue warnings for pollution events is also improved by assimilating the low-cost network with respect to the other simulations. Finally, the simulation using the high-quality configuration has lower error values than using the complete low-cost network, showing that it is essential to consider the quality and location and not just the total number of sensors. Our results suggest that with the current advance in low-cost sensors, it is possible to improve model performance with low-cost network data assimilation.

Dramatic Shift

The Belizean culinary landscape has experienced a dramatic shift in recent years, with an abundance of “fresh” and “local” dishes (i.e., salads) appearing on restaurant menus. While many tourists appreciate the option of ordering salad, there is a truly local green that might be equally or better suited to the tourist market given what we know about tourists’ interests in both authenticity and healthful eating. This paper explores both host and guest attitudes towards chaya, a leafy green that is high in protein and may have anti-diabetic properties. We argue that tourists enjoy eating chaya but restauranteurs are not taking advantage of its potential as a sustainable, low-cost dish that could also help preserve traditional foodways. Though restauranteurs are apt to cite supply chain issues as one of the reasons they are reluctant to make chaya a menu mainstay, we also believe that when a food occupies an ambiguous place in the local foodscape—as chaya does—local hosts may be unable to leverage it to is full potential.

Selenization Process

A facile low-cost non-vacuum process for fabrication of high quality CuInSe2(CIS) films is described, which indicates a promising way for the application in thin film solar cells. First, citrate-capped Cu11In9alloy nanoparticles are synthesized by hot-injection method after a system research on the different reaction time and Cu-In ratio of the raw materials. From the TEM and XRD results, we can see that uniform spherical nanoparticles with dominant Cu11In9phase and less particle-to-particle agglomeration are successfully achieved in this study. Then, employing spray and RTP selenization process, high quality CIS films with dense and big grains are obtained, which show the single chalcopyrite structure and the preferred (112) orientation. An energy band gap about 1.01 eV is measured through the absorption spectroscopy measurement in our work.
