Security of Attachment as a Predictor of Symbolic and Mentalising Abilities: A Longitudinal Study

The development of symbolic and mentalising abilities was examined in 33 children whose security of attachment had been assessed in infancy. It was found that securely attached children: (i) were better able to incorporate an experimenter's play suggestions into their sequences of symbolic play at 31 months; and (ii) performed better on a version of Wimmer and Perner's (1983) unexpected transfer task at age 4. There was also evidence of superior mentalising abilities among the secure group at age 5, despite no group differences being found in general cognitive ability. We suggest that these security-related differences might be related to mothers' propensity to treat their securely attached children as individuals with minds. In support of this hypothesis, mothers in the secure group adopted more sensitive tutoring strategies, and were more likely to describe their children in terms of their mental characteristics. Possible developmental pathways linking security of attachment in infancy with subsequent development were investigated using path analyses.     

Effects of omitting a covariate in poisson models when the data are balanced

The authors show that for balanced data, the estimates of effects of interest and of their standard errors are unaffected when a covariate is removed from a multiplicative Poisson model. As they point out, this is not verified in the analogous linear model, nor in the logistic model. In the first case, only the estimated coefficients remain the same, while in the second case, both the estimated effects and their standard errors can change.     

Has Social Security Become Irrelevant?

In recent years, it has often been asserted that social security has become irrelevant to contemporary economic and social realities. This claim has been accompanied by proposals for the abolition of social security and its replacement with commercial provision. In some countries, social security has already been extensively privatized. Instead of dismissing the claim that social security has become irrelevant, this article examines the views of social security's critics. It suggests that steps need to be taken to address their challenge and ensure social security's long-term survival.     

Integrating Internet-Based Distance Guidance With Services Provided in Career Centers

The Internet has evolved so rapidly that there is little information on integrating Internet-based distance guidance opportunities with resources and services provided by existing career centers. In this article, the author describes career centers and then explores the need for career centers in the information age, the types of Internet web sites, the functions of an integrated web site in promoting cost- effectiveness, options for integrating user needs, the role of instructional design in web site development, cost-effectiveness and staff collaboration, web master responsibilities, Internet web site implementation, staff training, and ethical issues. This article is based on a paper presented at a seminar titled, “Guidance in Open Learning Environments in the Finnish Polytechnics” at Espoo-Vantaa Polytechnic, Vantaa, Finland, 1998.     

The Effects of Auditory Tact and Auditory Imagining Instructions on the Emergence of Novel Intraverbals

The current research investigated whether intraverbals would emerge following auditory tact instruction. Participants were first taught to tact auditory stimuli by providing the name of the item or animal that produces the sound (e.g., saying “eagle” when presented with the recording of an eagle cawing). Following test probes for simple intraverbals as well as intraverbal categorization participants were taught to tact what each auditory stimulus is (e.g., saying “caw” when presented with the recording of an eagle cawing). Following both tact instructional phases, the effects of an auditory imagining instruction procedure on target intraverbals were examined. Results indicate that following both tact instructional phases, intraverbals increased for three of four participants. Auditory imagining instruction was sufficient for two of four participants to reach mastery criterion, and two of four participants needed some direct instruction. Low covariation between simple intraverbal and categorization was also observed. Functional interdependence between tacts and intraverbals and the possible role of a conditioned hearing response are discussed.     

Unionization and faculty salaries: New evidence from the 1990s

The literature on how unionization affects faculty salaries and compensation is inconclusive. I use the 1993 National Survey of Postsecondary Faculty to investigate how collective bargaining affects faculty salaries. Union representation significantly alters the returns to individual and institutional characteristics, and unionized faculty receive a premium of between 7 and 14 percent, an earnings differential that is substantially larger than those found in most earlier studies.     

Latinos and the Skin Color Paradox

For African Americans and Latinos, skin color is a significant predictor of many social and economic stratification variables including income, education, housing, occupational status, spousal status, poverty rates, criminal justice sentencing, and rates of depression. Given these patterns, some scholars have surprisingly found that skin color is not a significant predictor of many political attitudes for African Americans, and called this phenomenon the “skin color paradox.” This article investigates the role of skin color, race, and national origin in predicting political marginality and political commonality among Latinos. The models suggest that skin color is not a significant predictor of political attitudes, consistent with the skin color paradox theory but that national origin does predict some political attitudes.     

Reports of Conferences,Institutes, and Seminars

A busy time for librarians was late May through early July 2008 with the Ohio Valley Group of Technical Services Librarians meeting May 14–16, the North American Serials Interest Group meeting June 5–8, and an American Library Association preconference Electronic Serials 101: What I Wished I’d Known Before I Got in Over My Head, June 27.
