Urban forest cover of the Chicago region and its relation to household density and income

Urban forests and herbaceous open space play a vital role in the environmental and aesthetic health of cities, yet they are rarely identified in land-use inventories of urban areas. To provide information on urban forests and other vegetative land cover in Illinois cities, Landsat Thematic Mapper (TM) data from June 27, 1988, were classified for the Chicago metropolitan region (9,717 km²). Ten land-cover classes were identified, including two types of forestland (occupying 5.8% of the total area), residential land with trees (14.6%) or without trees (7.8%), cropland (37.5%), two types of grassland (7.7%), urban with impervious surfaces (23.1%), water (1.6%), and miscellaneous vegetation (2.1%). Correlation analyses indicated that household income and household density are strongly related to land covers in the region, particularly those with tree cover and urbanized land. Population changes for 1980–1985 and 1985–2010 (projected) show a pattern of increasing density in the urbanized zone concurrent with continued urban sprawl, primarily into current cropland.     

Vocal Coordination During Early Parent–Infant Interactions Predicts Language Outcome in Infant Siblings of Children with Autism Spectrum Disorder

This study examined vocal coordination during mother–infant interactions in the infant siblings (high‐risk infants; HR) of children with autism spectrum disorder (ASD), a population at heightened risk for developing language delays (LDs). Vocal coordination between mothers and HR infants was compared to a group of low‐risk (LR; no first‐ or second‐degree relative with ASD) dyads and used to predict later language development. Nine‐month‐old infants were video‐taped at home playing with their mothers, and interactions were coded for the frequency and timing of vocalizations. Percent infant simultaneous speech was predictive of later LD, and dyads with LD infants were less coordinated with one another in average latency to respond than dyads with non‐delayed (ND) infants. The degree of coordination between mothers and infants on this variable predicted a continuous measure of language development in the third year. This research underscores the importance of understanding early development in the context of interaction.     

Posture Development in Infants at Heightened versus Low Risk for Autism Spectrum Disorders

Evidence suggests that children and adults diagnosed with autism spectrum disorders (ASD) exhibit difficulties with postural control. Retrospective video studies of infants later diagnosed with ASD indicate that infants who eventually receive an ASD diagnosis exhibit delays in postural development. This study investigates early posture development prospectively and longitudinally in 22 infants at heightened biological risk for ASD (HR) and 18 infants with no such risk (Low Risk; LR). Four HR infants received an autism diagnosis (AD infants) at 36 months. Infants were videotaped at home at 6, 9, 12, and 14 months during everyday activities and play. All infant postures were coded and classified as to whether or not they were infant‐initiated. Relative to LR infants, HR infants were slower to develop skill in sitting and standing postures. AD infants exhibited substantial delays in the emergence of more advanced postures and initiated fewer posture changes. Because posture advances create opportunities for infants to interact with objects and people in new and progressively more sophisticated ways, postural delays may have cascading effects on opportunities for infant exploration and learning. These effects may be greater for infants with ASD, for whom posture delays are more significant.     

Distributive Justice Evaluations in Two Cultural Contexts: A Comparison of U.S. and South Korean Teachers

The justice literature suggests, but has nottested, a positive relationship between met expectationsabout multiple workplace rewards and distributivejustice evaluations (the individual's assessment of whether s/he has been treated fairly). Datafrom samples of teachers in South Korea (N = 649) andthe U.S. (N = 810) are used to examine thisrelationship. In addition, U.S.-South Korea culturalvalue differences in individualism, seniority, and hierarchicalauthority are the basis for hypothesizing that certainreward-specific met expectations will be linkeddifferently to justice evaluations across the twosocieties. As hypothesized for both societies, the moreone's expectations about job-related rewards are met,the greater the perception of just treatment. Also ashypothesized, several societal differences based on cultural differences are found. Metexpectations about autonomy are more important inexplaining justice evaluations in the U.S., whereas metexpectations about advancement opportunities are moreimportant in South Korea.     

The contribution of childhood family violence on later intimate partner violence among robbery victims

This study examined the relative contributions of the three forms of childhood family violence exposure on physical intimate partner violence (IPV) victimization among recent robbery victims and tested a gender-matching modeling prediction for IPV risk. Data from a sample of 103 male and 93 female victims of a robbery were analyzed to investigate the effects of exposure to childhood physical abuse (CPA), childhood sexual abuse (CSA), and witnessing parental violence on the likelihood of IPV in adulthood. As expected, witnessing parental violence was associated with a 2.4-fold increase in IPV for both men and women. Neither CPA nor CSA was significantly associated with IPV after accounting for the effect of witnessing parental violence. There was support for the gender-matching hypothesis with men more likely to report IPV if they had witnessed mother-to-father violence and women more likely to report IPV if they had witnessed father-to-mother violence. Witnessing parental violence is strongly associated with risk for IPV victimization, particularly when the victim is the same-gender parent. Future directions and clinical implications are discussed.     

Managing electronic documents and work flows: Enterprise content management at work in nonprofit organizations

Web management and knowledge management systems have made significant technological advances, culminating in large information management systems such as enterprise content management (ECM). ECM is a Web‐based publishing system that manages large numbers of electronic documents and other Web assets intended for publication to Web portals and other complex Web sites. Work in nonprofit organizations can benefit from adopting new communication technologies that promote collaboration and enterprisewide knowledge management. The unique characteristics of ECM are enumerated and analyzed from a knowledge management perspective. We identify three stages of document life cycles in ECM implementations—content, reification, and commodification/process—as the content management model. We present the model as a mechanism for decision makers and scholars to use in evaluating the organizational impacts of systems such as ECM. We also argue that decision makers in nonprofit organizations should take care to avoid overly commodifying business processes in the final stage, where participation may be more beneficial than efficiency.     

Antecedents of Union Commitment: The Impact of Union Membership Differences in Vertical Dyads and Work Group Relationships

Relational demography has recently been employedto investigate the influence of workplace diversity onorganizational outcomes, such as organizationalcommitment, turnover, and performance (O Reilly,Caldwell, & Barnett, 1989; Tsui & O Reilly, 1989;Tsui, Egan, & O Reilly, 1992; Tsui, Egan, &Porter, 1994). In the present study, we utilize thetechniques and theoretical framework employed in the relational demography literature to examine theimpact of heterogeneous union membership status withinwork groups and vertical dyads, and the effect of thesedifferences on union commitment. A composite dataset was created from two Australianhospitals. Analyses of the data were confined to 460nursing staff who could be identified within 43 specificwork groups (hospital wards). The results indicate that while no relationship was found betweendifferences in membership status among co-workers inwork groups on commitment, differences between membersand their supervisors served to decrease union loyalty and belief in unionism (controlling for otherunion and organizational factors). Importantly, we foundsupport for an interaction effect between work groupsand vertical dyads. Differences in membership status among co-workers were observed to lowerunion loyalty and willingness to work for the union whensupervisors were nonunion members. The implications ofsuch findings for union policy are addressed.     

Schools uniting neighborhoods: the SUN initiative in Portland, Oregon

The SUN Community Schools Initiative is a community-driven model that allows each school community to design the programs that fit neighborhood needs in Portland, Oregon. County and city governments, local school districts, and community agencies have jointly leveraged resources to support fifty-one community schools. The program is managed by the Multnomah County Department of School and Community Partnerships. The City Parks and Recreation Bureau oversees twelve sites staffed by city employees. Strong support across political systems aligns funding and reduces the fragmentation in existing funding patterns.     

Object exploration during the transition to sitting: A study of infants at heightened risk for autism spectrum disorder

Learning to sit promotes infants' object exploration because it offers increased access to objects and an improved position for exploration (e.g., ). Infants at heightened risk (HR) for autism spectrum disorder (ASD) exhibit delays in sitting and differences in object exploration. However, little is known about the association between sitting and object exploration among HR infants. We examined changes in object exploration as HR infants (N = 19) and comparison infants with no family history of ASD (Low Risk; LR; N = 23) gained experience sitting independently. Infants were observed monthly from 2.5 months until 1 month after the onset of independent sitting. At 12, 18, 24, and 36 months, infants completed standardized developmental assessments, and HR infants were assessed for ASD symptoms at 36 months. Although HR infants began sitting later than LR infants, both groups increased time spent grasping, shaking, banging, and mouthing objects as they gained sitting experience. Groups only differed in time spent actively mouthing objects, with LR infants showing a greater increase in active mouthing than HR infants. Findings suggest that HR infants experience a similar progression of object exploration across sitting development, but on a delayed time scale.
