Families and Schools The Effect of Parental Involvement on High School Completion

Abstract: This study examined European American, Latino, Asian American, and Native American parental involvement and their children’s high school completion. An examination of how different family structures have an influence on a student’s education was conducted. This study used the National Education Longitudinal Study (NELS) of 1988 and utilized a hierarchical linear model (HLM) for the statistical analysis. Social capital theory and a family ecological approach were used as the theoretical foundations. The findings demonstrated that different types of parental involvement were importantin a student’s highschool completion, dependingon ethnicity. Schoolinvolvement was not significant in influencingthe level of parental involvement and the relation to high school completion. Future research should focus on understandingthe ways in which a stronger relationshipbetween families and educational systems could be developed.

Artificial substrates which release nutrients: Effects on periphyton and invertebrate succession

Abstract: Nutrient-diffusing substrates for periphyton were made from clay flower pots (O.D. = 8.8 cm), sealed with plastic petri dishes, and filled with 2% agar and specified nutrients. When placed in water, the nutrients slowly diffuse through the agar and clay walls of the pots, becoming available to organisms colonizing the outer surface. Forty-eight pots, 16 containing 0.1 M KH2PO4, 16 with 0.1 M NaNO3, and 16 with no added nutrients, were placed at 0.5 m depth in Douglas Lake, Michigan. Four pots of each nutrient treatment were sampled for algal periphyton and invertebrates after 7, 14, 25, and 36 days. A total of 72 algal species were enumerated. Of these, Epithemia adnata (Kutz.) Breb., Rhopalodia gibba (Ehr.) O. Mull, and Anabaena sp. experienced strong growth stimulation in response to phosphate addition. No significant effects of nitrate addition were noted. Measures of algal community structure also reflected the impact of phosphate addition. Final algal biomass was enhanced 10-fold, successional change was prolonged, and species diversity declined relative to nitrate and control pots. Chironomids, chydorid Cladocera, and gastropods dominated the invertebrate fauna found on the pots. Densities of the small, algivorous chironomid Corynoneura nr. lobata Edwards were highest on phosphate pots at the end of the study, in apparent response to the increase in periphyton biomass.

The evolution and termination of an iron-induced mesoscale bloom in the northeast subarctic Pacific

Abstract: We initiated and mapped a diatom bloom in the northeast subarctic Pacific by concurrently adding dissolved iron and the tracer sulfur hexafluoride to a mesoscale patch of high-nitrate, low-chlorophyll waters. The bloom was dominated by pennate diatoms and was monitored for 25 d, which was sufficiently long to observe the evolution and termination of the bloom and most of the decline phase. Fast repetition‐rate fluorometry indicated that the diatoms were iron-replete until day 12, followed by a 4‐5-d transition to iron limitation. This transition period was characterized by relatively high rates of algal growth and nutrient uptake, which pointed to diatoms using intracellularly stored iron. By days 16‐17, the bloom was probably limited simultaneously by both iron and silicic acid

A Derivation of the Underlying Constructs of Just-In-Time Management Systems

Abstract: Researchers have recommended that the theoretical constructs underlying just-in-time (JIT) management systems be identified and developed if JIT is to be fully understood and its full capabilities realized. In this study, we advanced this conceptual development through an instrument based on the relevant literature and empirically deriving three underlying constructs: (1) operating structure and control, (2) product scheduling, and (3) quality implementation. We report a content analysis of these constructs and develop propositions regarding their relationships, predecessors, and outcomes.
