Conditioned taste aversion in Philippine rice rats (R. r. mindanensis): Comparisons among drugs,dosages, modes of administration,and sexes

The effects of select drugs, dosages, and modes of administration upon learned taste aversions were compared among groups of wild-caught male and female Philippine rice rats (R. r. mindanensis). Experiment 1 compared two-choice saccharin aversions for 28 days among groups intubated with copper sulfate, cyclophosphamide, lithium chloride, red squill, sodium chloride (control), or deionized water (control). Main results were that 375 mg/kg lithium chloride produced the greatest sustained aversions, whereas 198 mg/kg cyclophosphamide and 210 mg/kg red squill produced moderate aversions, with males showing more resistance to extinction than females. Experiment 2 compared saccharin aversion among matched groups of male and female rats that received low (36 mg/kg), moderate (105 mg/kg), or high (368 mg/kg) dosages of lithium by gavage, ip injection, or ingestion. Sex differences in rates of extinction were found for the ingestion and injection-dosed rats, but no sex difference was again found for rats dosed by gavage. A significant mode × day interaction indicated that extinction progressed more rapidly for rats dosed by gavage. For all modes of administration, high dosages yielded intense 28-day aversion, moderate dosages produced intermediate 3–5 day aversion, and low dosages caused no aversion.     

Family Interaction Patterns,Career Planning Attitudes,and Vocational Identity of High School Adolescents

The purpose of the current study was to examine how perceptions of family interaction patterns as defined along three dimensions of family environment (quality of family relationships, family goal-orientations, and degree of organization and control within the family system) predict vocational identity and career planning attitudes among male and female adolescents living at home. One hundred twenty three high school students completed measures of family environment, vocational identity, and career planning attitudes. Analyses revealed that the quality of family relationships (i.e., degree to which family members are encouraged to express feelings and problems) played a small, yet significant role in predicting career planning attitudes of adolescents.     

Recreational activities and motor skills of children in kindergarten

Background: Developmental theorists suggest that physical activity during early childhood promotes fundamental motor skill (FMS) proficiency; and that differences in FMS proficiency are largely related to children's experiences.

Aim: To examine associations between participation in different types of recreation/leisure and FMS proficiency of boys and girls in their first year of school. We hypothesized that there would be positive associations between FMS proficiency and participation in organized sport, physical activities, and active physical recreation; but not for other types of recreation/leisure.

Method: Participants (n?=?74) were kindergarten children (Mage?=?5y11?m; boys?=?55%). Parents completed the diversity dimension of the Children's Assessment of Participation and Enjoyment (CAPE) survey. The CAPE measures children's participation in everyday activities outside of mandated school activities in the past four months in five types of formal and informal activities, specifically: Recreational activities, Physical activities, Social activities, Skill-Based activities, and Self-Improvement activities. Two categories of activities were also reported: Organized Sport and Active Physical Recreation. Locomotor and object control skills were assessed using the Test of Gross Motor Development-2 and static balance was assessed using a stork stand. Sex-based differences in motor skills and participation were examined using chi-squared analyses. Correlation coefficients were used to examine relationships between motor skills and CAPE sub-domains and categories. Linear regression was used to examine whether the type of activity predicted motor skill proficiency and the reverse.

Results: There were no sex-based differences in locomotor skills; whereas boys' object control skill scores were significantly higher than girls, and girls' stork stand scores were higher than boys'. Although there were no sex-based differences in the more active categories of recreational pastimes; girls participated in significantly more formal and informal dance and the prevalence of participation in team sports was significantly higher for boys. For boys, participation in physical activities predicted both locomotor and object control skill scores, organized sport predicted object control skills, and active recreation predicted stork stand times and object control skill scores. These relationships were not evident among the girls.

Conclusions: These findings illustrate that young children participate in a narrower array of physically active recreational pursuits compared with less active pursuits. There were notable sex-based differences in the relationships between participation and motor skill proficiency. For girls, none of the associations between recreational pastimes and motor skill proficiency were significant. This suggests that the motor proficiency of girls, as assessed in this study, is neither a precursor to, nor an outcome of, participation in active recreational pastimes. Contrastingly, the findings for boys support theory that suggests that physical activity is driving the acquisition of particular types of motor skills. Less active recreational activities were not associated with motor skill levels of boys, whereas each of the more active categories of recreational pastimes (active recreation, physical activities, and organized sport) predicted at least one sub-type of motor skill. It also seems clear from our findings that more light needs to be shed on how to optimally portray young girls' motor skill proficiency; as well as the relationships between their participation and motor skills.     

UK Research Reserve: Working Together to Establish a National Collection

This article describes the history, structure and workings of the UK Research Reserve, a national collaborative programme to release space in Higher Education Libraries and secure copies of print journals. The program's key processes are described to illustrate how a national collection of copies for access and preservation is created using coordinated de-duplication and shared storage. Achievements to date and possibilities for future developments are outlined.     

Stages of a cyber-writing partnership

New technologies are changing what we understand by distance and what we interpret as personal relationships. “Working together” is a phrase with a whole new set of relationships in this networked universe. In this article, two writers, who collaborated on a project long before they ever met face to face, describe the challenges of building up a writing relationship in the comparative vacuum of the ether. They describe what happened when, partway through the extended writing project, they finally met and got to work in the same room for a few days, and then consider what happened subsequently. They draw from their own experience of collaboration some principles for the development and support of collaborative writing in school.     

One-Stop Shopping: Merging Service Points in a University Library

ABSTRACT

As libraries change to meet the evolving needs of our patrons, including the development of online services, many libraries are considering consolidating physical service points to maximize staff and better serve the in-house patron. This article describes the planning, implementation, and evaluation process involved in merging the circulation and reference desks at the University of New Orleans Library. The cross-training process is described in detail, and benefits as well as problems experienced are outlined. The authors also provide advice for those considering a merge at their library.     

The Measurement of Child Behavior in Terms of Its Social Stimulus Value

This study proposed to determine the policy of a single university department concerning admissions to the doctoral program. A Q-sort technique was used with several attributes of each graduate listed on an index card. The twelve members of the graduate faculty rated each graduate by placing a profile into one of seven piles. The number in each pile was fixed. Each rater’s policy was captured by using multiple linear regression. With the use of the Judgment Analysis technique (JAN), the raters were placed into appropriate clusters, and it was found that at least two separate judgment systems were present.     

The function or debate

Classical debate involves orderliness and freedom of speech. There are debates in Homer, the earliest surviving Greek author. The debates in Thucydides, Demosthenes, and the reported Roman debates in the handbook of Seneca the Elder turn upon issues of freedom of speech which are not without relevance for our time; even in a time of absolutism Roman orators kept the spark of freedom alive.
