Toddlers' Attachment Security to Child-Care Providers: The Safe and Secure Scale

Attachment relationships of toddlers (N = 45) to their child-care providers were investigated. Children's behaviors with their mothers were observed at home at 24 months and with their child-care providers at 26 months. Attachment Q-Sort procedures were used at home (90 items) and in child care (78 items); the latter yielded a 15-item Safe and Secure Scale describing the safe haven and secure base functions of attachment relationships in child care—being able to (a) seek and receive positive attention, (b) feel safe and protected, (c) receive support for exploration, (d) receive consolation when distressed, and (e) seek and accept assistance. Independent observational measures of child-care quality also were obtained at 24 months. As hypothesized, the Safe and Secure Scale was related to proximal rather than distal indicators of child-care quality, and it was a stronger measure than the child-caregiver Q-security score that was based on all 78 items. Child-mother and child-caregiver security were significantly related.     

Career Counseling for Longevity: Self-Care and Burnout Prevention Strategies for Counselor Resilience

Balancing self-care and other-care is often a struggle for career counselors and others in the helping professions. The process of caring is made up of a constant series of empathic attachments, active involvements, and felt separations. The ability to continually engage in the caring cycle is important for success. However, the constant need to re-create the cycle of caring can lead to counselor depletion and burnout. This article provides a developmental framework for assisting career counselors to avoid depleted caring while prolonging their professional longevity. The model of self-care includes recognizing the hazards of high touch work, such as limited resources and constant one-way caring. Also addressed are specific means of professional and personal sustenance, such as maximizing experiences of professional success and balancing personal wellness throughout one's career.     

Prevalence,School Progress and Referral of Mildly Retarded Children in Regular Classes

This study sought to determine the prevalence of mildly retarded children in a sample of 312 primary school classes (N (pupils) = 8,967). Schools were chosen at random from each of the eight Psychological Service districts of metropolitan Auckland; all Grade 2‐5 classes in the sample schools were included in the investigation. Eighty percent of the teachers surveyed believed they had one or more mildly retarded children in their classes, yielding an overall prevalence rate of 8.04 percent (N = 721). Approximately one‐third of the children designated as mildly retarded were considered by their teachers to be not coping academically as well as socially, but of these 75 percent had not been referred for special educational consideration. Comparisons among the eight districts revealed that prevalence/referral rates and characteristics of identified/referred children did not differ significantly across districts. Results are discussed in terms of their policy implications for the identification and referral of mildly retarded children in need of special educational services.

Header error control schemes for coping with upstream channel noise in the HFC network

The Hybrid Fiber-Coax (HFC) network is being paid close attention to in recent years as a bi-directional broadband access network. To achieve seamless connection with the backbone network, and Asynchronous Transfer Mode (ATM) Network Network Interface (NNI) cell format is used as the basic transmission packet unit in the HFC system. As the transmission condition of the HFC system’s upstream channel is bad, two improved header error control (HEC) schemes, i. e. the improved HEC and the cell interleaving technique, are employed to guarantee the packet integrity. Theoretical analysis of the results showed that the improved HEC and the cell interleaving technique are applicable to isolated random errors and burst errors, respectively.
