An Evaluation of Immersive and Handling Methods for Collecting Salamander Skin Peptides

Free-riding is a serious challenge in group projects. While there are various methods to reduce free-riding, marketing educators still face a difficult task when selecting an appropriate method for their course. In this study, we propose a students’ preferences-based approach that supports marketing educators with the selection of methods to detect and handle free-riding. To measure these preferences, students completed an online survey based on a choice task about two methods to detect free-riding and a ranking task about four methods to handle free-riding ( n = 254). Their answers were analyzed using chi-squared tests, Borda scores, and rank-ordered logit models. The results show that (a) neither Dutch nor international students have a clear preference for one of the two detection methods (the reporting system vs. the process evaluation system), (b) grade discussion (a possible reduction of the free-rider’s grade based on a conversation with the course coordinator about each student’s contribution) is the most preferred method to handle free-riding, and (c) international students have a stronger preference for stricter handling methods. Marketing educators can apply the proposed approach, or use our specific findings, for designing methods to reduce free-riding in their courses.

Ethical Reflections

AbstractThe thoughts presented here describe the »Reality« of money and its Connections, in the sense oft he point of attachment, to an ethic of »Money«. The respective theological remarks to the descriptions integrate, strenghten and interpret these and thus present perspectives for the handling of money without, however, providing handling methods. A functional view of the social and economic sciences is not sufficient for a description of money by means of (the theological) ethics. Although ethics must have knowledge of this »Rationality«, yet the many methods of talking of and money are an indication for ethical reflections that behind the functional reality of money there lurks an »Ethical« dimension (money, wealth, power;justice, goodness, solidarity; time is money, insatiability, magic, idolatry of money) which require tobe deciphered and interpreted.

Motivated by recent advancements in differential evolution and constraints handling methods, this paper presents a novel modified oracle penalty function-based composite differential evolution (MOCoDE) for constrained optimization problems (COPs). More specifically, the original oracle penalty function approach is modified so as to satisfy the optimization criterion of COPs; then the modified oracle penalty function is incorporated in composite DE. Furthermore, in order to solve more complex COPs with discrete, integer, or binary variables, a discrete variable handling technique is introduced into MOCoDE to solve complex COPs with mix variables. This method is assessed on eleven constrained optimization benchmark functions and seven well-studied engineering problems in real life. Experimental results demonstrate that MOCoDE achieves competitive performance with respect to some other state-of-the-art approaches in constrained optimization evolutionary algorithms. Moreover, the strengths of the proposed method include few parameters and its ease of implementation, rendering it applicable to real life. Therefore, MOCoDE can be an efficient alternative to solving constrained optimization problems.

Handling Methods

Die Lkw-Produktion ist durch eine große Variantenvielfalt gekennzeichnet. Speziell die Montage ist geprägt von einem hohen Anteil manueller Prozesse. Schwere und sperrige Bauteile und Werkzeuge müssen gehoben, geführt, positioniert und oft bei engen Toleranzen gefügt werden. Die Entwicklung eines intelligenten, teilautomatisierbaren Unterstützungssystems soll zur Verbesserung der Ergonomie, der Akzeptanz, Arbeitssicherheit, Qualität und Prozesszeit der Handhabungsaufgaben beitragen.   Truck manufacturing is characterized by a high variety. Especially in assembly, a high proportion of manual processes is involved. Heavy and bulky parts and tools must be lifted, transported, positioned, and joined by close tolerances. The development of an intelligent and partially automatable assist device will help to improve ergonomics, user acceptance, safety, quality and process time of handling operations.

Apart from traditional optimization techniques, e.g. progressive optimality algorithm (POA), modern intelligence algorithms, like genetic algorithms, differential evolution have been widely used to solve optimization problems. This paper deals with comparative analysis of POA, GA and DE and their applications in a reservoir operation problem. The results show that both GA and DES are feasible to reservoir operation optimization, but they display different features. GA and DE have many parameters and are difficult in determination of these parameter values. For simple problems with mall number of decision variables, GA and DE are better than POA when adopting appropriate parameter values and constraint handling methods. But for complex problem with large number of variables, POA combined with simplex method are much superior to GA and DE in time-assuming and quality of optimal solutions. This study helps to select proper optimization algorithms and parameter values in reservoir operation.

Definition Of

Indonesia as a country which did not ratify UN Convention 1951 on Status of Refugees and Protocol 1967, issued a Presidential Decree No.125/2016 on Handling Overseas Refugee in addressing the issues of foreign nation subject who intend to seek refuge by passing through Indonesian territory, generally aiming to seek refuge in Australia. These foreign nation subject introduced as “refugee” by media although the subject is unrecognized by Indonesian immigration law system. Indonesian immigration law only recognize subject as a person who enter or leave Indonesian territory by legal or illegal means. The definition of Refugee on Presidential Decree No.125/2016 is the first definition of the subject in Indonesian legal system, refers to both Refugee and Asylum Seekers in UN Convention 1951, which supposed to have different handling methods. Therefore, the implementation of Presidential Decree No.125/2016 leads to different understanding in immigration and foreign policy perspective on Refugee subject.

Handling Methods

A national mail survey focusing on consumer handling of fresh fruits and vegetables was conducted among 2,000 randomly selected households in the United States. The objective was to quantify consumer practices relating to the purchase, transport, storage, and preparation of fresh produce, with emphasis on practices that affect safety. Following an additional mailing procedure, a response rate of 33% was obtained. Six percent of the consumers responded that they seldom or never wash fresh produce, and more than 35% indicated that they do not wash their melons before preparation. Twenty-three percent of the respondents indicated placing their meat, poultry, and fish on a refrigerator shelf above other foods, and 9% do not place their produce at any specific location in the refrigerator. Almost half of the respondents indicated not always washing their hands before handling fresh produce. Ninety-seven percent of respondents reported that they always wash their food preparation surfaces after contact with meat products, yet 5% and 24% dry wipe or wash with water only, respectively. The results from this study suggest that women, lower-income households, people 65 years and older, and non–college graduates practice safer food handling methods than men, higher-income households, people younger than 65 years, and college or postcollege graduates. The survey findings suggest that consumer education materials should emphasize safe handling practices from purchase through consumption. Educational outreach should target specific subpopulations, men, college graduates, higher-income households, and people younger than 65 years because of their higher frequency of unsafe handling and washing practices.
