Maintenance is one of the main drivers for ensuring the sustainability of manufacturing in capital-intensive production systems. However, in many cases, as a result of budgetary constraints, it is necessary to select which machines will be subject to maintenance actions on the basis of a list of priorities. Traditionally, such prioritization decisions are made using techniques which, in general, do not consider the systemic impact of maintenance actions. This paper is focused at the definition of a novel graphical technique for physical assets prioritization. This technique is aimed at establishing maintenance priorities considering the impact on the overall throughput of the production system. Due to the fact that the proposed technique is based on the well-known Overall Equipment Effectiveness (OEE) index, its use is not only limited to measuring the effects of maintenance decisions and actions (availability), but also to operational implications (productivity and utilization). The results could be displayed graphically, which makes it particularly useful and manageable for different types of users. The methodology is illustrated though an example based on a comminution plant from the copper mine industry. It is evident how the proposed technique facilitates business-oriented and economic sustainability focused decisions.

The article discusses the problem of choosing ways and means of pragmatic adaptation in translating a text. The relevance of the topic is due to the necessity to facilitate cross-cultural communication in view of the increased intensity and diversity of forms of international contacts. The definition of pragmatic adaptation as the actions of a translator aimed at adapting the source language text to its perception by a recipient belonging to a different culture, does not answer the questions of when and how a translator can and should change the text in order to preserve the pragmatic potential of the original. The aim of the article is to analyze the problems arising in translating texts requiring pragmatic adaptation and evaluate the impact of different types of pragmatic adaptation on reproducing the pragmatic potential of the original and achieving the possible purposes of translation. In order to do it an experiment was carried out: a text was translated in four different ways with different means used for its pragmatic adaptation, and the translations were compared. The results of the experiment show that the choice of pragmatic adaptation methods and techniques is determined not by the type of text or the type of adaptation, as is usually believed, but by the specific purpose for which the text is translated. Thus, when translating a literary text, which always contains factual, conceptual, emotional, aesthetic, and cultural information, the choice between the naturalness of the text, the preservation of the author’s style, the completeness of the content and the communication of culturally relevant information means, in fact, setting different accents. The means of pragmatic adaptation used by the translator depend entirely on the prioritization of these types of information, in other words, on the purpose of translation.

The Relationship

In this paper I will argue that artificial moral agents (AMAs) are a fitting subject of intercultural information ethics because of the impact they may have on the relationship between information rich and information poor countries. I will give a limiting definition of AMAs first, and discuss two different types of AMAs with different implications from an intercultural perspective. While AMAs following preset rules might raise con-cerns about digital imperialism, AMAs being able to adjust to their user‘s behavior will lead us to the question what makes an AMA ?moral?? I will argue that this question does present a good starting point for an inter-cultural dialogue which might be helpful to overcome the notion of Africa as a mere victim.

The Impact

Structural representations for interfaces between modules and components in a product vary widely in the literature. After reviewing several structural approaches to interface definition, a new weighted design dependency measure is described. The new representation takes into account both six different types of interfaces as well as their relative strength and frequency within a product architecture. The resulting design dependency measure provides a means for designers to quantify the change resistance in a product. In this paper, we investigate the use of this new design dependency measure to drive module identification. Specifically, we compare the resulting modules obtained by optimizing Design Structure Matrices (DSMs) using standard 0-1 representations of the interfaces to those obtained using the new design dependency measure. The results indicate that the weighted design dependency measure leads to more a logical definition of modules that maximizes within module dependencies and minimizes interactions between modules.

In recent years, topology optimization methods are becoming more widely used in many engineering fields, and they are already being successfully integrated at the design stage of the different types of products. An active field of research in this area is the definition of appropriate constraints in topology optimization models in order to facilitate the production of the optimized objects. An algorithm for topology optimization of housing elements from gear reducers by using the capabilities of CAD-CAE topology optimization software is presented in the current work. The purposed algorithm is taking into account the resulting loads during operation of the reducer, the geometrical and manufacturing constraints of the production process of these housing elements. Obtained results from conducted Taguchi experimental study to investigate the impact of some topology optimization control parameters over optimized 3D-model also are shown and discussed. Conclusions on the applicability of the algorithm have been made.

Few studies have investigated the emerging category of Pro-Ams and its impact on knowledge markets over the Internet. We tend to address this gap in our study. Our research proposes a formal framework of knowledge expertise with mass amateurization and analyzes its impact on Internet-based knowledge markets. Specifically, the new definition of knowledge expertise consists of three major components: primary, searching, and learning expertise. Due to the effect of mass amateurization, questions posted by knowledge seekers on Internet-based knowledge markets are more likely to be answered by knowledge providers, resulting in more knowledge transactions to be consummated. This paper also discusses the impact of mass amateurization on different types of Internet-based knowledge markets. This research provides valuable insights for practitioners to manage knowledge markets with effective policies.

The Impact

Public transport networks (PTN) are affected daily by different types of disturbances. In fact, between a single delay and a long service interruption, there is a range of disruptions with different impacts, depending on their characteristics. Despite this, in literature, the common definition of disruption is a link closure for a certain amount of time. Low interest is given to different types of disruptions or to the connection between delays and disruptions. In addition, in multimodal PTN a physical link closure is not always observable, but rather people experience delays or cancelled stops on different lines. The aim of this work is to explore the relationship between delays and disruptions, analyzing different degrees of disruptions, in relation to duration, delay, size, and network characteristics. Real disturbances of the PTNs in Zürich and Bern, Switzerland, are analyzed to identify disruptions with different characteristics. Therefore, the disruption impact is computed on simulated origin–destinations (ODs), based on the sets of possible paths with and without the disruption. For this purpose, a choice set generation algorithm is used. Finally, relationships between the disruption characteristics and the impact are analyzed to identify the main features of a disruption.

Model Approach

Pilgrimage centers are important elements of the spatial structure of cities and simultaneously factors influencing their transformations. The pilgrimage function of sanctuaries can lead to development of service zones around them focused mainly on serving visitors, i.e., pilgrims and tourists. They often perform functions complementary to sanctuaries. Here we present the results of studies of sanctuary service zones conducted at twenty six popular Catholic sanctuaries in Europe. In this paper, we discussed the influence of the sanctuary on city space on the macro, meso and micro scales. We proposed a definition of a sanctuary service zone, and developed a model approach to the different types: initial (slightly developed) zones, dispersed zones (integrated into the urban space, with their pilgrimage function coexisting with other urban functions), and compact zones—linear, or pilgrimage districts (with dominating pilgrimage function). The development of sanctuary service zones depends mainly on the rank of the pilgrimage center, as well as on the period in which it was founded, pilgrimage traditions, and the location of the pilgrimage center in the city. This paper is a continuation and extension of research into the impact of pilgrimage centers on city space transformations in the context of socio-cultural changes in the 20th and 21st centuries.

Projective Riccati Equation Method

Abstract Nonlinear Schrödinger’s equation and its variation structures assume a significant job in soliton dynamics. The soliton solutions of space-time fractional Fokas–Lenells equation with a relatively new definition of local M-derivative have been recovered by utilizing improved $\tan (\frac{\phi (\eta )}{2})$ tan ( ϕ ( η ) 2 ) -expansion method and generalized projective Riccati equation method. The obtained solutions are periodic, dark, bright, singular, rational, along with few forms of combo-soliton solutions. These solutions are given under constraints conditions which ensure their existence. The impact of local fractional parameter is featured by its graphical portrayal. 2D and 3D diagrams are drawn to illustrate the efficacy of the conformable fractional order on the behavior of some of those solutions. The secured solutions of this model have dynamic and significant justifications for some real-world physical occurrences. Our study shows that the suggested schemes are effective, reliable, and simple for solving different types of nonlinear differential equations.

Abstract. Two studies carried out among Albanian public-sector employees examined the impact of different types of affirmative action policies (AAPs) on (counter)stereotypical perceptions of women in decision-making positions. Study 1 (N = 178) revealed that participants – especially women – perceived women in decision-making positions as more masculine (i.e., agentic) than feminine (i.e., communal). Study 2 (N = 239) showed that different types of AA had different effects on the attribution of gender stereotypes to AAP beneficiaries: Women benefiting from a quota policy were perceived as being more communal than agentic, while those benefiting from weak preferential treatment were perceived as being more agentic than communal. Furthermore, we examined how the belief that AAPs threaten men’s access to decision-making positions influenced the attribution of these traits to AAP beneficiaries. The results showed that men who reported high levels of perceived threat, as compared to men who reported low levels of perceived threat, attributed more communal than agentic traits to the beneficiaries of quotas. These findings suggest that AAPs may have created a backlash against its beneficiaries by emphasizing gender-stereotypical or counterstereotypical traits. Thus, the framing of AAPs, for instance, as a matter of enhancing organizational performance, in the process of policy making and implementation, may be a crucial tool to countering potential backlash.
