Identifying demand for private education at an urban Catholic college preparatory high school: a study of similarities and differences in parental motivation

The purpose of this study was to identify and compare the factors that motivate parents/guardians to enroll their admitted student in Catholic College Prep: an urban, Catholic, college preparatory high school, with factors that motivate parents/guardians of admitted students to enroll them elsewhere. This quantitative, cross-sectional study, conducted by the researcher over one admissions cycle (September 27th to January 7th) was used to restructure and improve Catholic College Preparatory High School\u27s marketing planning and action. The researcher investigated this topic using the following questions as guides: 1. What factors, if any, do parents/guardians perceive to be very important in motivating them to apply to and enroll their children in a Catholic, college preparatory high school during the fall 2010 admission\u27s cycle? 2. What factors, if any, do parents/guardians perceive to be very important in motivating them to apply to a Catholic, college preparatory high school to which, upon acceptance, they choose not to enroll during the fall 2010 admission\u27s cycle? 3. How do the factors, if at all, perceived to be very important in motivating families to apply to a Catholic, college preparatory high school compare between parents/guardians who apply to and enroll at a Catholic, college preparatory high school with parents/guardians who choose not to enroll their admitted students during the fall 2010 admission\u27s cycle? This study was descriptive in design and utilized a likert scale survey for data collection. The survey\u27s purpose was to identify the motivating factors for families who were pursuing Catholic College Preparatory High School. The survey contained 26 questions with a 3 likert scale response structure. Study findings suggest that families who apply to and are accepted at an urban Catholic college preparatory high school are motivated by academic reputation and college preparation. Findings also revealed that families who were accepted and registered were motivated by moral training while families who were accepted and chose not to register were motivated by teachers. Responses for both subpopulations yielded important insight into the motivations for families who pursue and are accepted at an urban Catholic college preparatory school as well as prompted need for further study

Assessment of Natural Resources Use for Sustainable Development - DPSIR Framework for Case Studies in Portsmouth and Thames Gateway, U.K.

This chapter reports on the uses of the DPSIR framework to assess the sustainability of the intertidal environments within the two UK case study areas, Portsmouth and Thames Gateway. It focuses on statutory conservation areas dominated by intertidal habitats. Two are located in Portsmouth (Portsmouth and Langstone Harbours) and four in the Thames Gateway (Benfleet Marshes, South Thames Estuary, Medway Estuary and the Swale in the Thames Gateway). Based on the reduction of a number of pressures and impacts observed in recent decades and the improvement of overall environmental quality, all six SSSIs are considered to be sustainable in the short and medium term. In the future, it is possible that the impacts of climate change, especially sea-level rise, might result in further reduction in the area and/or quality of intertidal habitats. Further integration between conservation and planning objectives (both for urban development and management of flood risk) at local level is needed to support the long-term sustainability of intertidal habitats

Lifting restrictions on coherence loss when characterizing non-transparent hypersonic phononic crystals

Abstract Hypersonic phononic bandgap structures confine acoustic vibrations whose wavelength is commensurate with that of light, and have been studied using either time- or frequency-domain optical spectroscopy. Pulsed pump-probe lasers are the preferred instruments for characterizing periodic multilayer stacks from common vacuum deposition techniques, but the detection mechanism requires the injected sound wave to maintain coherence during propagation. Beyond acoustic Bragg mirrors, frequency-domain studies using a tandem Fabry–Perot interferometer (TFPI) find dispersions of two- and three-dimensional phononic crystals (PnCs) even for highly disordered samples, but with the caveat that PnCs must be transparent. Here, we demonstrate a hybrid technique for overcoming the limitations that time- and frequency-domain approaches exhibit separately. Accordingly, we inject coherent phonons into a non-transparent PnC using a pulsed laser and acquire the acoustic transmission spectrum on a TFPI, where pumped appear alongside spontaneously excited (i.e. incoherent) phonons. Choosing a metallic Bragg mirror for illustration, we determine the bandgap and compare with conventional time-domain spectroscopy, finding resolution of the hybrid approach to match that of a state-of-the-art asynchronous optical sampling setup. Thus, the hybrid pump–probe technique retains key performance features of the established one and going forward will likely be preferred for disordered samples

Grape VOCs response to postharvest short-term ozone treatments

Ozone has been recently recognized as an efficient sanitizing agent in wine industry because of its powerful oxidizing properties. Furthermore, postharvest treatments of grapes with ozone can stimulate defense responses by synthetizing secondary metabolites against oxidative stress. In this study, the effect of postharvest short-term ozone treatments was assessed for the first time on free and glycosylated volatile organic compounds (VOCs) of winegrapes. Two different ozone concentrations (30 and 60 μL/L) and exposure times (24 and 48 h) were investigated just after treatment (fresh grapes) and after partial dehydration up to 20% weight loss (withered grapes). The study was carried out on Moscato bianco winegrapes (Vitis vinifera L.) due to the importance of terpenes in white aromatic cultivars to produce high quality wines. The results obtained showed that short-term ozone treatment caused a significant decrease in total contents of free VOCs in fresh grapes, mainly due to terpenes. Among them, linalool, geraniol, and nerol are the major aromatic markers of Moscato bianco grapes. Ozone entailed a significant decrease of free linalool contents in fresh grapes, the less stressful ozone treatment showing the smaller linalool degradation. However, the stronger and longer ozone treatment induced the synthesis of this compound probably in response to higher abiotic stress. Instead, significant changes were not observed in geraniol and nerol contents in fresh grapes. This last ozone treatment also reduced the loss of free linalool by water loss in withered grapes even though total VOCs and terpenes remained relatively stable. Furthermore, ozone seems to promote the synthesis of free (+)-4-carene and 4-terpineol in withered grapes under certain treatment conditions. Regarding glycosylated compounds, total VOCs and terpenes were less sensitive to ozone. Our findings highlight that ozone can be used as sanitizing agent in aromatic grape varieties prior to winemaking without affecting sharply the aromatic profile of fresh grapes and even improving it in withered grapes
