Simplified method of designing FIR filter with controllable center frequency

A novel simplified method is presented to design FIR filter with controllable center frequency. The properties of transfer curves for all-phase filters are illustrated under 3 windowing conditions. By combining single-window all-phase filter design steps and double phase-shift combination, a series of design formulas for point-pass filter, notch filter, band-pass filter and band-stop filter are derived, thus the design computation complexity is greatly reduced. Experiments prove that the center frequency of all the filters can be accurately specified at arbitrary position by adjusting frequency parameters m and λ.     

Mental health care for foster children in California

This paper reports on a study conducted to assess the health care needs of foster children in California. To evaluate foster children's mental health problems and the services provided to meet them, 154 program administrators, social workers, foster parents, and health care providers were interviewed in 14 counties. Foster parents and social workers were interviewed in groups, and foster parents and administrators also completed questionnaires. We found that although all counties care immediately for children who are injured, abused, or ill, only one county performs routine mental health evaluations of all children, and in most counties less than a third of children ever receive such evaluations. Informants identified mental health problems as more severe than medical problems in this population, and they identified four major barriers to access to appropriate therapy. Recommendations are that all children should receive comprehensive mental health evaluations, and procedures for immediate and ongoing care with consistent providers who are sensitive to foster children's needs should be included in case management plans, and covered by improved payment mechanisms. Additionally, communication, coordination and joint planning should be instituted among relevant agencies to address foster children's needs, and increased resources and training should be directed towards social service agencies and foster parents.     

“Oh,I’m Here!”: Social Media’s Impact on the Cross-cultural Adaptation of Students Studying Abroad

This study investigates the perceptions and interpretations of social media and online communication by students engaged in study abroad programs. In-depth interviews were conducted and analyzed with 23 American and international students who completed or were engaged in a study abroad program. Results suggest that online communication enhanced the students’ experience, providing help with sociocultural skills, informational needs, relational bonds, and psychological well-being. Different platforms were preferred when communicating with friends versus family and intimates. Online communication between co-nationals from the student’s home country buffered both the sojourning student’s acculturative stress, and the stress and concern of distant family members.     

Culturally and Linguistically Relevant Readalouds

The teacher readaloud is an instructional tool established in its ability to foster children's language and literacy development. Increasing cultural and linguistic diversity and changing standards place pressure on teachers to provide literacy and language instruction relevant to children's everyday lives and learning. This article presents a framework for conducting culturally and linguistically relevant readalouds within two essential components, talk and text, in terms of developing cultural competence, maintaining high academic expectations, and fostering a critical stance. Particular attention is given to the interactive nature of these readalouds and how they can be used to promote children's active co-construction of textually-based meaning.     

Materials Research in France: A Short-lived National Initiative (1982–1994)

This paper describes the French initiative in materials research against both a national and an international background, in an attempt to disentangle the local circumstances, which prompted this governmental initiative, and to characterize the specific profile of materials research in France. In presenting a biography of the interdisciplinary program in materials research (PIRMAT), we argue that: i) the PIRMAT denotes a failure of the French science policy in materials research; ii) the leadership of the CNRS led to a specific style of research, quite different from the engineering approach of Materials Science and Engineering, and characteristic of a French style in materials research.     

National,Regional and Global Perspectives of Higher Education and Science Policies in the Arab Region

In this paper we discuss the interaction between science policies (and particularly in the area of scientific research) and higher education policies in Gulf and Mediterranean Arab countries. Our analysis reveals a discrepancy between the two sub-regions with respect to integration in the global market, cooperation in scientific research and international mobility of students. The paper discusses the implications of the analysis of reform policies and higher education restructuring.     

Prediction as an Impediment to Preparedness: Lessons from the US Hurricane and Earthquake Research Enterprises

No matter one’s wealth or social position, all are subject to the threats of natural hazards. Be it fire, flood, hurricane, earthquake, tornado, or drought, the reality of hazard risk is universal. In response, governments, non-profits, and the private sector all support research to study hazards. Each has a common end in mind: to increase the resilience of vulnerable communities. While this end goal is shared across hazards, the conception of how to get there can diverge considerably. The earthquake and hurricane research endeavors in the US provide an illustrative contrast. The earthquake community sets out to increase resilience through a research process that simultaneously promotes both high quality and usable – preparedness-focused - science. In order to do so, the logic suggests that research must be collaborative, responsive, and transparent. Hurricane research, by contrast, largely promotes high quality science – predictions - alone, and presumes that usability should flow from there. This process is not collaborative, responsive, or transparent. Experience suggests, however, that the latter model – hurricane research - does not prepare communities or decision makers to use the high quality science it has produced when a storm does hit. The predictions are good, but they are not used effectively. Earthquake research, on the other hand, is developed through a collaborative process that equips decision makers to know and use hazards research knowledge as soon as an earthquake hits. The contrast between the two fields suggests that earthquake research is more likely to meet the end goal of resilience than is hurricane research, and thus that communities might be more resilient to hurricanes were the model by which research is funded and conducted to change. The earthquake research experience can provide lessons for this shift. This paper employs the Public Value Mapping (PVM) framework to explore these two divergent public value logics, their end results, and opportunities for improvement.
