The migration of Zimbabweans into South Africa is shaped by several factors and processes. Traditionally, the decision to migrate was mostly based on family considerations (where gender stereotypic roles were a priority), although in some cases the migrants exercised individualism and personal agency. This led to migration trends that were male dominated. Current Zimbabwean migration trends reflect large volumes of women as the socio-economic crisis forces them to leave their country. These migrant women encounter a myriad of challenges in their host countries. This paper explores Zimbabwean women’s migration to the town of Mthatha in South Africa, highlighting their challenges and the strategies they employ to overcome these, as found in a recent case study. Applying a qualitative research design and using questionnaires and interviews to gather data from the 100 purposively sampled women, the study found that many Zimbabwean migrant women in Mthatha encountered numerous challenges. They lacked the required documents to live and work in South Africa, experienced exploitation and marriage constraints, and had broken ties with their families back in Zimbabwe. According to the study, these women managed to navigate these challenges, rising above the stereotypic norms and values that used to label them as non-productive citizens to superheroes who were supporting their families and the country’s economy—thus breaking the shackles of gender stereotyping to create new norms. These findings underline the importance of shifting from the traditional approaches to women migration and pursuing perspectives that present migration as a critical component of the process of social change and development to all migrants.

Decision Making Units

AbstractThe conventional data envelopment analysis (DEA) measures the relative efficiency of decision making units (DMUs) consuming multiple inputs to produce multiple outputs under the assumption that all the data are exact. In the real world, however, it is possible to obtain interval data rather than exact data because of various limitations, such as statistical errors and incomplete information, et al. To overcome those limitations, researchers have proposed kinds of approaches dealing with interval DEA, which either use traditional DEA models by transforming interval data into exact data or get an efficiency interval by using the bound of interval data. In contrast to the traditional approaches above, the paper deals with interval DEA by combining traditional DEA models with error propagation and entropy, uses idea of the modified cross efficiency to get the ultimate cross efficiency of DMUs in the form of error distribution and ranks DMUs using the calculated ultimate cross efficiency by directional distance index. At last we illustrate the feasibility and effectiveness of the proposed method by applying it to measure energy efficiency of regions in China considering environmental factors.

AbstractThis paper presents a case study of model predictive control (MPC) applied to a continuous stirred tank reactor (CSTR). It is proposed to approximate nonlinear behavior of a plant by several local linear models, enabling a piecewise affine (PWA) description of the model used to predict and optimize future evolution of the reactor behavior. Main advantage of the PWA model over traditional approaches based on single linearization is a significant increase of model accuracy which leads to a better control quality. It is also illustrated that, by adopting the PWA modeling framework, MPC strategy can be implemented using significantly less computational power compared to nonlinear MPC setups.

The Impact

The emerging of digital technology not only encourages the development of new tools but also changes traditional approaches to solving emerging problems. The sound, music, art, colors, etc. that prevailed in the 20th-century forms of therapy are being replaced by integrated systems that overcome many of these forms, thanks to digital technology. With the increasing number of people with autism spectrum disorder (ASD) in the world, such systems provide new opportunities for the treatment of these disorders. In this research, the creation of such a system has been chosen as the object of work. The article presents an interactive tool for the education of children with ASD created by audio, video, and computer technologies and assesses its potential impact. The experimental research and its results are presented. This study aims to evaluate an interactive instrument developed for the education of such children. Following the objectives of ensuring the interactivity of the process, provoking all the perceptions of the subject, and developing the subject's ability to respond to the environment, a personalized audiovisual environment was created. For interactivity, the virtual program EyeCon, Webcam and camcorders, video projector, and speaker system were used. The study was conducted with one subject and a case study method was used. The impact of the instrument was established based on a survey of the parents of the child and the findings of childcare experts. The results of the study demonstrated the positive benefits for this child such as increased eye-to-hand coordination, concentration duration, improved communication, and emotional expression. The results obtained show that such interactive multi-sensory environments in special and general education schools can be a supplemental tool for traditional methods.

Goal Models

While traditional approaches in business process modeling tend to focus on “how” the business processes are performed (adopting a behavioral description in which business processes are described in terms of procedural aspects), in goal-oriented business process modeling, the proposals strive to extend traditional business process methodologies by providing a dimension of intentionality to business processes. One of the key difficulties in enabling one to model goal-oriented processes concerns the identification or elicitation of goals. This paper reports on a case study conducted in a Brazilian hospital, which obtained several goal models represented in i*/Tropos, each of which correspond to a business process also modeled in the scope of the study. NFR catalogues were helpful in goal elicitation, uncovering goals that did not come up during previous interviews prior to these catalogues’ use.

Despite the significant progress made by research into e-business models, the issue of how public sector organisations can successfully make the transition from traditional approaches to e-business by taking advantage of e-technologies has received little attention. This chapter draws on qualitative, longitudinal case-study research carried out between 2001 and 2005 in Britain’s national mapping agency to reveal the processes of strategic and organisational transformation engendered by E-business in an organisation evolving from the classical, bureaucratic and centralised ‘public sector model’ towards a new organisational form through embracing e-business as a corporate philosophy. The study also explores the key components of the new e-business model implemented by the organisation and the contextual factors that impacted on the effectiveness of E-strategy implementation in order to draw a list of best practices for the implementation of E-business in a public sector context.

The Impact

This chapter introduces a community facilitation model for e-government. The central tenet of this approach is the empowerment of a segment of the population to act, by providing the tools and information necessary to tackle issues that have been difficult to address with traditional approaches to government. Under this model, government provides an initial spark and then plays a supporting role in the growth of the community. By doing so, the costs of the program are minimized while the impact of the program is maximized. We examine the viability of the model by looking at a case study in water quality monitoring. The case illustrates the power of a government facilitated community of action to address an important problem, and it suggests that such a model can be applied globally and may be relevant to government initiatives beyond water monitoring.

A brief discussion of two traditional approaches in the study of pottery production organization, ceramic ecology and typologies of production, identifies several key problems. In order to move forward and develop new strategies, it is proposed to adopt a symmetrical perspective, integrating methods and concepts from a variety of theoretical origins, including chaîne opératoire, object biography, relevant user groups or cadena, and entanglement. A brief case study outlining a proposed strategy for a relational approach to the study of ceramic production organization concludes the chapter.

It is fair to say that religion, and in particular the ways in which some Christian and Islamic thinkers have again begun to encroach on the domain of science (e.g., global warming, the teaching of evolution), has caused a great deal of consternation within the scientific and philosophical communities. An understandable reaction to these developments is to reject out of hand even the slightest taint of religion in these fields—a position that has now attained the status of orthodoxy, at least in the western world. This is curious on its face, given the fact that religion has clearly provided a sense of meaning and purpose for most of our fellow humans as long as there have been humans pondering such things. Moreover, it is probably not necessary, provided one is very careful what sort of faith one endorses. Thus, the basic question I wish to address here, albeit in a very preliminary fashion, is whether it may be possible to delineate a form of faith that can inspire and guide humanity without the metaphysical baggage that causes conflict with epistemically conservative disciplines like science. To that end, I examine one recent thread within cosmology that views the universe as creative in the sense that it is biased towards the production of ever-increasing complexity at its edges. If that is true, it gives those so inclined permission, as it were, to view the creation of complexity (including human culture and its products) as a moral good (perhaps even an imperative) without the assumption of supernatural entities with mysterious motives and goals. After arguing that there is indeed logical space for such a faith that does not impinge on the essential commitments of either science or philosophy (properly conceived) I will examine its potential use in framing some of the emerging debates concerning space exploration. The prospect of humanity venturing beyond our homeworld in the near future offers an excellent case study of this “neo-naturalism” in action for two basic reasons. First, it seems likely that such a massive and complex undertaking needs a motivational source beyond mere discovery and expansion. Second, a neo-natural faith may influence how we go about this, and not always in ways those steeped in more traditional approaches to religion would predict.

The advance in the digital world has caused a growth of complexity in innovation. Traditional approaches to innovation, based on reductionism, face greater difficulties. That is why we have witnessed the growth of those known as System of Systems (SoS). There is a wide variety of methodologies and domains of application in the literature to form framed solutions in the context of SoS, but there is no unified consensus for its use and even less when it comes to agile environments of continuous integration and deployment in which traceability requirements are critical. In recent years, the need to have traceability software that continuously records and monitors the trace of the entities that interact with it has become an essential feature. In addition, over the years there has been evidence of errors caused by poor traceability control. Therefore, this document presents an agile framework that aims to guarantee the traceability of a SoS from the early stages. This framework unifies the discovery, development and operations, providing full coverage in the conformation of the solution. Finally, we present a case study as future work, which is based on the application of our framework on smart laboratories for assisted reproduction.
