Drivers for and against municipal wastewater recycling: a review

The reclamation, treatment and reuse of municipal wastewater can provide important environmental benefits. In this paper, 25 studies on this topic were reviewed and it was found that there are many (\textgreater150) different drivers acting for and against wastewater recycling. To deal with the challenge of comparing studies which entailed different research designs, a framework was developed which allowed the literature to be organized into comparable study contexts. Studies were categorized according to the level of analysis (wastewater recycling scheme, city, water utility, state, country, global) and outcome investigated (development/investment in new schemes, program implementation, percentage of wastewater recycled, percentage of water demand covered by recycled water, multiple outcomes). Findings across comparable case studies were then grouped according to the type (for or against recycling) and category of driver (social, natural, technical, economic, policy or business). The utility of the framework is demonstrated by summarizing the findings from four Australian studies at the city level. The framework offers a unique approach for disentangling the broad range of potential drivers for and against water recycling and to focus on those that seem relevant in specific study contexts. It may offer a valuable starting point for building hypotheses in future work.

Gain dependent pulse regimes transitions in a dissipative dispersion-managed fibre laser

For the first time, we demonstrate the possibility to switch between three distinct pulse regimes in a dissipative dispersion-managed (DM) fibre laser by solely controlling the gain saturation energy. Nonlinear Schrödinger equation based simulations show the transitions between hyper-Gaussian similaritons, parabolic similaritons, and dissipative solitons in the same laser cavity. It is also shown that such transitions exist in a wide dispersion range from all-normal to slightly net-normal dispersion. This work demonstrates that besides dispersion and filter managements gain saturation energy can be a new degree of freedom to manage pulse regimes in DM fibre lasers, which offers flexibility in designing ultrafast fibre lasers. Also, the result indicates that in contrast to conservative soliton lasers whose intensity profiles are unique, dissipative DM lasers show diversity in pulse shapes. The findings not only give a better understanding of pulse shaping mechanisms in mode-locked lasers, but also provide insight into dissipative systems.

A felsőoktatási képzések munkaerő-piaci szempontból (Higher education programs from point of view of labor market)

A munkaerő-piaci követelményeknek megfelelően kialakított képzések versenyképesebbek a társaiknál. A napjainkban is zajló magyar felsőoktatási reform központi elemét alkotja a képzések ennek megfelelően történő átalakítása. Mindez létjogosultságot ad egy olyan rendszernek, amely a Budapesti Corvinus Egyetem gazdaságinformatikus BSc-képzésének kompetenciaelemeit kívánja vizsgálni az állásajánlatokban megnyilvánuló munkaerő-piaci igények tükrében. Az ontológiaalapú módszertan egy egységes fogalmi kört biztosít a munkaerőpiac eltérő szemléletű oldalán kifejlesztett modellek egységesítésére és összehasonlítására. ____ Tendencies can be observed on international and domestic levels that call for restructuring of higher education according to the needs of labor market. This paper presents an information system that can investigate the compliance of education programs and current labor market needs. Competences serve as a basis for this compliance checking, which is built on ontologybased approach. Having examined the distribution of roles (developer, operator etc.) appeared in IT job offers in time and space, a prototype of this system will be showed, related to Business Informatics degree program at Corvinus University of Budapest.

The researchers in this study analyzed the self-identified leadership skills and key indicators of leadership as revealed by the written narratives of a group of teacher leaders. These teachers are graduates of a job-embedded, on-site degree program that uniquely combines collaborative professional development and school reform.

Guatemala: A Failing State?

 Guatemala is not a failed state and is unlikely to become one in the near future. Although the state currently fails to provide adequate security to its citizens or an appropriate range of effective social programs, it does supply a functioning electoral democracy, sound economic management, and a promising new antipoverty program, My Family Progresses (MIFAPRO).  Guatemala is a weak state. The principal security threats represented by expanding Mexican drug trafficking organizations (DTOs), criminal parallel powers, and urban gangs have overwhelmed the resources of the under-resourced and compromised criminal justice system. The UN-sponsored International Commission against Impunity in Guatemala (CICIG), however, has demonstrated that progress against organized crime is possible.  The principal obstacles to strengthening the Guatemalan state lie in the traditional economic elite’s resistance to taxation and the venal political class’ narrow focus on short-term interests. Guatemala lacks a strong, policyoriented, mass-based political party that could develop a coherent national reform program and mobilize public support around it.  The United States should strengthen the Guatemalan state by expanding the Central America Regional Security Initiative (CARSI) and by strongly supporting CICIG, MIFAPRO, and the Supreme Electoral Tribunal (TSE).

China's Relations with Brazil and Argentina and Implications for U.S. Security Concerns [Student's Paper Series]

This study on China’s relations with Brazil and Argentina, as well as its implications for U.S. concerns examines two main questions: Why China’s increasing influence on Brazil and Argentina may be considered a cause for U.S. security concerns? And if this is the case, how do China’s strategic alliances with the two countries has impacted U.S. leadership? In an effort to look at China’s influence from multidimensional angles and beyond China’s visible economic influence in these two countries, this paper argues that China’s interest in the Latin American region, with a focus on brazil and Argentina, responds to a more crafted, pragmatic and tailored vision with long-term strategic and political goals. The results of this study reveal that China – avoiding intra-regional competition through a strategic diversification of sectors – has been able to secure critical resources for its population as well as promote enduring alliances in the region that could represent a plausible cause of concern for U.S. interests. In this regard, China’s avoidance of a direct challenge to traditional partners’ influence has responded to the gaps left by a gradual, but steady lack of U.S. involvement.

Changing Attitudes And Expectations In A University Setting: A Case Study

First and second year students enrolled in a four-year movement education based university Physical Education program completed a questionnaire regarding their expectations on entering university. In addition, graduates of the program were interviewed, one year after graduation, with regard to their understanding of and attitude towards movement education and how these had developed relative to their overall degree program. Most students had no knowledge of movement education prior to entering the program and the selection of this particular program was simply coincidental with their desire to pursue physical education. Whereas the students did participate in an activity course and a theory course in Year 1, it was only when participating in a Year 2 movement course which combined theory and practice within the same course that students recognized the movement base of the content. The progress of the students through the program reflects distinct declarative and procedural stages in knowledge development followed by an ability to generalize that knowledge a conceptual stage. The real understanding of movement education came as the students were required to teach movement education to students, children, and other groups.

Diagnóstico del rendimiento académico de estudiantes de una escuela de educación superior en México

El objetivo del artículo es realizar un diagnóstico sobre la percepción de los factores que intervienen en el rendimiento académico de los estudiantes de cinco carreras universitarias en una escuela de educación superior en México, para así reconocer las áreas de oportunidad que permitan sugerir políticas y estrategias para elevar su rendimiento. Se utilizó una muestra de 1651 estudiantes, se obtuvieron los datos a partir de un cuestionario con treinta preguntas que estudian la percepción del rendimiento académico en escala tipo Likert. Se realizó un análisis factorial exploratorio que permitiera reducir los datos, facilitar la interpretación y validar el instrumento. Se identificaron tres factores: a) el rol de los profesores, b) la evaluación y c) la motivación de los estudiantes. Se llevó a cabo un análisis comparativo por carrera. Se encontró que los estudiantes perciben que la mayoría de los maestros no se preocupan por la condición de los jóvenes en situación de reprobación. Además, casi no motivan y carecen de expresiones de sentimientos de orgullo por los logros académicos de los estudiantes. La mitad de los participantes piensa que los docentes no cubren el temario en su totalidad. Se detectó que los estudiantes poseen una alta motivación siendo esto positivo porque son alumnos dedicados y responsables. Se concluye realizando una serie de sugerencias y explicando las implicaciones que tiene este trabajo para las instituciones de educación superior.
