Native Hawaiians and Bishop Museum: Negotiating Ownership of the Island Past

Increasingly, museums are seeking to incorporate indigenous perspectives into their exhibits, programs, and collections management policies. Despite its history and close proximity to Hawaiians, Bishop Museum has neither a long nor an unblemished record of consulting the indigenous community. Within the last three years, there has been a theft/removal of sacred objects, a lawsuit involving repatriation of Hawaiian remains, demonstrations and state government hearings concerning the Bishop's interpretation of archaeological sites, as well as more positive activity; e.g., a renewed interest in exhibiting Hawaiian culture. While factionalism within the indigenous community complicates matters, many of the museum's problems are an outgrowth of its own decisions: lucrative contracts have not been without cost, and internal dissension has resulted in such high staff turnover that the museum's professional capability has been publicly called into question by Hawaiians (and others). As Hawaiians assume a more active role, their 106-year relationship with Bishop Museum is being redefined. (Note: “Hawai'i” is used here to refer to the southernmost island in the chain; “Hawaii” designates the entire chain, the state).     

Semantic Similarity Search on Semistructured Data with the XXL Search Engine

Query languages for XML such as XPath or XQuery support Boolean retrieval: a query result is a (possibly restructured) subset of XML elements or entire documents that satisfy the search conditions of the query. This search paradigm works for highly schematic XML data collections such as electronic catalogs. However, for searching information in open environments such as the Web or intranets of large corporations, ranked retrieval is more appropriate: a query result is a ranked list of XML elements in descending order of (estimated) relevance. Web search engines, which are based on the ranked retrieval paradigm, do, however, not consider the additional information and rich annotations provided by the structure of XML documents and their element names.This article presents the XXL search engine that supports relevance ranking on XML data. XXL is particularly geared for path queries with wildcards that can span multiple XML collections and contain both exact-match as well as semantic-similarity search conditions. In addition, ontological information and suitable index structures are used to improve the search efficiency and effectiveness. XXL is fully implemented as a suite of Java classes and servlets. Experiments in the context of the INEX benchmark demonstrate the efficiency of the XXL search engine and underline its effectiveness for ranked retrieval.     

Visual‐Spatial Representation,Mathematical Problem Solving,and Students of Varying Abilities

The purpose of this study was to investigate students' use of visual imagery while solving mathematical problems. Students with learning disabilities (LD), average achievers, and gifted students in sixth grade (N= 66) participated in this study. Students were assessed on measures of mathematical problem solving and visual‐spatial representation. Visual‐spatial representations were coded as either primarily schematic representations that encode the spatial relations described in the problem or primarily pictorial representations that encode persons, places, or things described in the problem. Results indicated that gifted students used significantly more visual‐spatial representations than the other two groups. Students with LD used significantly more pictorial representations than their peers. Successful mathematical problem solving was positively correlated with use of schematic representations; conversely, it was negatively correlated with use of pictorial representations.     

Quality reference service: A preliminary case study

A general reference department achieved a high score on the Wisconsin-Ohio Reference Evaluation Program. Intensive use of electronic resources, a good reference collection, good architecture, administrative support, and, most importantly, adequate time provided by the consultation model contributed, in this case, to high-quality service.     

Auditory Context and Memory Retrieval in Young Infants

Three-month-old infants were trained to move an overhead crib mobile while 1 of 2 musical selections was played. Retention was assessed 1 or 7 days later in the presence of either the same music or a different musical selection. in Experiment 1, the musical selections were very different (classical versus jazz); in Experiment 2, they were much more similar (two classical pieces). Infants in both experiments displayed 1 day retention regardless of wich music was played during the retention test. At 7 days, retention was seen only when the music played during the retention test matched the training music. These data are consistent with similar findings showing that 3-month-old infants'memory is disrupted at long retention intervals when the context present during retention testing does not match the learning context. As the infant's memory wanes, context appears to function as a necessary cue for the retrieval of acquired expectancies.     

Lenghth of Maternity Leave and Quality of Mother-Infant Interactions

The aim of this study was to assess the association between the length of maternity leave and the quality of mother-infant interactions; 198 employed mothers of 4-month-old infants were interviewed and videotaped in their homes during a feeding time. Hierarchical multiple regression analyses indicated a direct association between shorter length of leave and more negative affect and behavior in maternal interactions with their infants. Infant and mother stressor/protective variables added significantly in predicting the quality of the mother-infant relationship. There were also significant interaction effects between the length of leave and these variables. Mothers who either reported more depressive symptoms or who perceived their infant as having a more difficult temperament and who had shorter leaves, compared with mothers who had longer leaves, were observed to express less positive affect, sensitivity, and responsiveness in interactions with their infants. The public policy implications of the relation between length of maternity leave, maternal and infant individual differences, and the quality of mother-infant interactions are discussed.
