1. Behavioral Activation Therapy for Depressed Cancer Patients: Factors Associated with Treatment Outcome and Attrition

Author

Hopko, D. R., Robertson, S. M. C., and Colman, L.

Abstract

In recent years there has been increased focus on evaluating the efficacy of psychosocial interventions for cancer patients. Among the several limitations inherent to these programs of research, few studies have targeted patients with well-diagnosed clinical depression and little is known about factors that best predict treatment outcome and attrition in this population. Using a heterogeneous sample of cancer patients, this study was designed to explore the relations of treatment outcome and attrition with selected demographic (age, education, marital status, gender), psychosocial (pretreatment depression and anxiety, number of co-existent disorders, social support) and medical variables (health and functional status, cancer type, and length of cancer diagnosis). Results indicated that positive treatment outcome was associated with fewer coexistent anxiety disorders at pre-treatment and involvement in a marital relationship. Attrition was more likely to occur among cancer patients presenting with higher pre-treatment depression severity and those who were less educated. Implications of these findings and study limitations are discussed. (Contains 2 tables and 1 note.)

Abstract

Sea turtles are vulnerable to climate change since their reproductive output is influenced by incubating temperatures, with warmer temperatures causing lower hatching success and increased feminization of embryos. Their ability to cope with projected increases in ambient temperatures will depend on their capacity to adapt to shifts in climatic regimes. Here, we assessed the extent to which phenological shifts could mitigate impacts from increases in ambient temperatures (from 1.5 to 3°C in air temperatures and from 1.4 to 2.3°C in sea surface temperatures by 2100 at our sites) on four species of sea turtles, under a “middle of the road” scenario (SSP2‐4.5). Sand temperatures at sea turtle nesting sites are projected to increase from 0.58 to 4.17°C by 2100 and expected shifts in nesting of 26–43 days earlier will not be sufficient to maintain current incubation temperatures at 7 (29%) of our sites, hatching success rates at 10 (42%) of our sites, with current trends in hatchling sex ratio being able to be maintained at half of the sites. We also calculated the phenological shifts that would be required (both backward for an earlier shift in nesting and forward for a later shift) to keep up with present‐day incubation temperatures, hatching success rates, and sex ratios. The required shifts backward in nesting for incubation temperatures ranged from −20 to −191 days, whereas the required shifts forward ranged from +54 to +180 days. However, for half of the sites, no matter the shift the median incubation temperature will always be warmer than the 75th percentile of current ranges. Given that phenological shifts will not be able to ameliorate predicted changes in temperature, hatching success and sex ratio at most sites, turtles may need to use other adaptive responses and/or there is the need to enhance sea turtle resilience to climate warming.

3. Teaching of Second Languages in the Context of the National Policy of Language Maintenance in Ireland, 1960-1970.

Author

O'Huallachain, Colman L.

Abstract

This paper surveys the teaching of second languages in Irish primary and post-primary schools. In the centralized primary school system, with primary teacher-training directed towards state-controlled qualifying examinations, government policy now favors the teaching of Irish side by side with English (also an official language). With the establishing of the Linguistic Institute of Ireland, a linguist was commissioned to outline a procedure permitting the production of materials for teacher training and remedial work. When trained personnel are available, further work will proceed to improve guidance and materials for teaching English in Ireland. The urgency of the task of saving the Irish language from extinction has so far directed most activities in applied linguistics and pedagogy toward improving the teaching of it as a second language in the greater part of the country where it has been superseded by English. "Buntus Gaelige" [Foundation-Beginnings in Irish], the results of the linguistic inquiry, is now officially presented throughout the entire school system with the aid of graded courses for the teaching of Irish as a subject from entry into primary schools up to the highest standard (4,500 primary schools outside the Irish-speaking areas). A special course for secondary level is also available. Interdisciplinary three-year programs are being planned. (AMM)

5. The Use of Principal Component Analysis to Classify PDMS Surfactants Used to Make Rigid Polyurethane Foams Based on Their Dynamic Surface Tension Characteristics

Author

Biesmans, G., Colman, L., and Vandensande, R.

Abstract

Polydimethylsiloxane surfactants are well known in the polyurethane industry. They play a vital role in the manufacture of both rigid and flexible foams. In order to achieve the phaseout of CFCs, as prescribed in the Montreal protocol, new blowing agents have been developed to make polyurethane foams. This has been accompanied by changes in the composition of the foam forming material including the silicone surfactants. This article describes a method for measuring the dynamic surface tension behavior of these silicone surfactants in model liquids representative of the polyol component in the foam forming mixture. The different dynamic surface tension characteristics of commercially available silicone surfactants are reported. In a second stage these data are analyzed using a chemometrics technique called principal component analysis. This allows the classification of the various surfactants in several subsets, each characterized by a specific dynamic surface tension behavior. The combined method of dynamic surface tension measurements and principal component analysis allows fast screening of surfactants used in the polyurethane industry.
