Selected aspects of the breeding biology of two Lake Erie herring gull colonies

Aspects of the breeding biology of two Lake Erie Herri ng Gull colonies were studied in 1975 and 1976. In 1976 the incubation attention given 2-egg and 3-egg clutches initiated early and late in the season was measured. Brood size at one colony was artificially increased or decreased by addition of chicks shortly after hatching. Hatching success was not consistently re~ated to clutch size but early nesters were more successful than late nes'ters. Differences in hatching success between 2-egg and 3-egg clutches were a function of the time of clutch initiation with the clutch size having the greater proportion of its nests initiated early in the season being more successful. The incubation attentiveness of parents of 2-egg and 3-ev,g , and early and late clutches was similar. Most nests were incubated greater than 95% of the time although t heir hatching success was similar ' to those incubated less than 75% of the time. Fledging success, chick growth and weight at fledging were similar among broods of one, two and three chicks and artificially increased broods of four and five chicks. Fledging success was highest for o.e chick broods reduced from two and three chick broods.

Academics as parents--parents as academics : a study of the integration of intellectual and child-care labours /

Discussions concerning the challenges of combining work and family are certainly not new, and still actively continue. There is, however, a silence in the related literature regarding a comprehensive description of integrating specifically university academic ~. work and family responsibilities. This silence is especially evident for men who are parents as well as academics. With the participation of 4 key informants, this qualitative research study gave voice to men and women who participate in the academic labour of a Canadian university as professors, and as graduate students, along with the parenting labour of at least 1 child under the age of7. Methodology was developed to reveal in-depth perspectives regarding the work practices employed by 4 key informants as they combined intellectual and child-care responsibilities. Multiple data collection methods included journal reflections, day time observation sessions, a focus group, and a final evaluation questionnaire. Using research findings, together with information extrapolated from Three Models of the Family (Eichler, 1997), this study also took steps toward developing a Proposed "Three Models of the University," to offer explanation for the work practices of the key informants as academics/parents, and also for future consideration in university policy formation.

Grade nine teachers' perception of how teachers, parents, peers, administrators, and community members affect the development of the grade nine student /

The purpose of this study was to examine grade nine teachers' perception of how teachers, parents, peers, administrators, and community members influence the overall development of grade nine students. Ten grade nine teachers (four male and six female) participated in the study which consisted of the completion of a one hour, tape-recorded interview. The central findings were as follows: 1) the grade nine student has evolved; 2) peers have an important impact on the four developmental areas (physical, emotional, social, and academic) of the grade nine student; and 3) the role of the grade nine teacher appears to have dramatically changed over the last seventeen years. Suggestions and recommendations for future research in this field are based on findings related to the enhancement of the secondary school experience for the grade nine adolescent.

The influence of investigator disturbance on aggressive behaviour and breeding success of ring-billed gulls (Larus delawarensis) /

Increased losses of eggs and chicks resulting from human intrusion (investigator or other) into seabird colonies has been well documented. In 1990/91, I studied the effects of investigator disturbance on aggressive behaviour and breeding success of individual pairs of ring-billed gulls nesting at two colonies near Port Colborne, Ontario. The insular colony was on an artificial breakwall, associated with the Welland Ship Canal, approximately 1 km off the north shore of Lake Erie. The mainland colony was adjacent to the canal approximately 1 km east of the breakwall. The frequencies of adult threat and assault behaviours, chick movement and adult attacks on chicks were recorded by continuous scan sampling 30 min prior to, 30 min during and 60 (2 X 30) min after investigator disturbance. The frequency of threat and assault behaviours increased during the period of investigator activity in the colony while the duration of wingpulls and beakpulls decreased. Significantly more chicks ran ("runners") from their natal territories during disturbances and "runners" were more frequently attacked than "territorial" chicks. No chicks were fatally attacked during disturbance and "runners" returned to their natal territories quickly after disturbance. Breeding success was determined for pairs nesting in study plots subjected to two levels of disturbance (normal and moderate). The disturbance level of each plot differed in visitation frequency and activities performed on each visit. Investigator disturbance had no effect on the hatching success or fledging success (taken as 21 days of age) of ring-billed gull study pairs at either colony.

Teaching Principled negotiation skills to parents and their children : the impact of parental involvement /

This study explored the impact of training parents and children concurrently in principled negotiation skills for the purpose of developing negotiation skills and problem solving abilities in children. A second experimental group was utilized to determine the viability of negotiation skills training of junior elementary students for the purpose of improving problem solving and conflict resolving abilities. The student population in each experimental group was trained using The Program for Young Negotiators (Curhan, 1996). A control group was also established using the remaining grade four and five students attending the participating school. These students did not receive training as part of this study. Student group distribution was as follows: Experimental group 1 (students with parent participant) consisted of 10 (5 grade five and 5 grade 4 students), Experimental group 2 students without parent participant) consisted of 48 (20 grade 4 and 28 grade 5 students), and the Control group 3 (55 grade 4 and 5 students). The impact of training was measured using the Five Factor Negotiation Scale developed for use with the Program for Young Negotiators (Curhan, 1996). This measure was employed as a pre- and post-test questionnaire to the total student population, (113 students) to determine levels of ability in each of the key elements of negotiation, personal initiative, collaboration, communication, conflict based perspective taking, and conflict resolution approach (Nakkula & Nikitopoulos, unpublished). This measure has a coefficient alpha of .75 which is acceptable for this type of affective instrument. As well, open ended ability questions designed to measure ability, knowledge, and behaviour as they relate to negotiation skill application were given to the total student population, (113 students). Finally, journals were maintained by the students in both experimental groups, and informal feedback discussions were held with students and parents participating in the study.The intent of using both qualitative and quantitative measures was to provide an overall perspective of student abilities as they related to principled negotiation skills. While the quantitative measures were from the student perspective, more qualitative information was sought from parents and teachers through informal interviews, discussions, and use of confidential feedback cards. For analysis purposes, the ability questions were randomly selected for Experimental group 2 and Control group 3 in an effort to balance the groups more equitably with Experimental group 1. The findings of this study indicate that students of the junior elementary school age can be taught how to perceive conflict in a more constructive way. However, they are not as likely to use their skills when the conflict is with a sibling as they are with a peer, a teacher, or a parent. While no statistically significant differences between mean scores for Experimental groups 1 and 2 exist some subtle differences are noted. Overall, increases in mean scores for grade 4 students exceeded the increases for grade 5 students within Experimental group 1 . The implication being that younger students benefit more from having a parent trained in principled negoUation skills than older students. The skill level of a parent in principled negotiation can not be underesUmated. Without a consistent and effective role model the likelihood of developing student skill level to a point of automaticity is greatly reduced. Enough so that perhaps the emphasis should be placed on training parents more so than the students.

Moral identity, youth engagement, and discussions with parents and peers /

The strength of adolescents' moral identity was examined in relation to their sense of social responsibility, frequency of community engagement, and interactions with parents and friends. Participants were 191 applicants to national youth conferences, ranging in age from 14-19, who completed a 40-minute survey. 76% of the participants were female. Social responsibility, community engagement, and discussion with parents and friends were measured using self-report questionnaires. Participants also reported on the importance of various values to themselves, their parents, and their friends, which were used to create an index of the degree of disagreement between the youth and their parents and friends. In addition, participants provided self-descriptions, which were used to measure moral identity with both a coding scheme and a ratings measure. Moral identity as measured by coding was not related to social responsibility, community engagement, or any other study variables, and thus did not appear to be a valid measure of moral identity. However, moral identity as measured by ratings was related to both social responsibility and community engagement, and thus appeared to be a valid measure. Neither disagreement nor discussion with friends was related to moral identity. However, disagreement with parents was positively related to moral identity ratings, and for girls only was negatively related to social responsibility. Furthermore, discussion with parents was positively related to moral identity for boys only. The hypothesis predicting a mediational model was not supported. Results were discussed in terms of theoretical positions on the role of parents and friends in children's moral development and suggestions for ftiture research were made.

Exploring the experiences of parents with children who have communication delays, as a population at risk for the development of behavioural concerns

Existing research identifies preschoolers with communication delays as a population at risk for the development of behavioural concerns. This risk increases when additional environmental factors such as parental stress and family conflict are also present. Research has also shown that behavioural concerns can be stable over time when they develop early. However, early intervention has been shown to be effective in addressing these concerns. The effectiveness of early intervention in addressing both child and family outcomes increases when interventions are delivered in a family-centred approach. This research project made use of data related to child behaviour and parenting, gathered through the Family Resource Project which explored the parenting experiences and resource access and allocation decisions of families who have preschool children with and without communication delays. Cluster analysis was used to explore whether there were identifiable clusters of children and families within each sample. Interview data fi"om each identified family cluster was then explored further, to identify how parents described their child's behaviour and their experience of parenting. Results show that, within this sample, parents of preschoolers with communication delays described their child's behaviour and their experience of parenting differently than did parents of children without communication delays. Results also showed that within this sample parents experiencing parental stress and/or family conflict described their child's behaviour and their experience of parenting differently than did parents from other clusters. Results suggest support for early intervention and the use of family-centred intervention, particularly for families of children with communication delays.

A study on the role of the parent in educational decision making from the perspective of parents and teachers

ADeweyan (1916) democratic theoty ofeducation called for the participation ofall citizens in deliberating important educational issues to improve overall student learning. Thus, the move to include parents in educational decision making can be considered to be rooted in democratic principles. To gain greater insight into the issue ofparent involvement in educational decision making, one elementary school was studied and a triangulization method was employed in an attempt to clarify the important issues surrolUlding the move to include parents in the governance ofschools. The three methods to gain information included surveys, interviews, and documentation ofsignificant school events and related work. All ofthe parents and teachers ofthe school were surveyed, 10 parents and 6teachers were interviewed, and related school events were recorded. The survey design was modeled on the Parent Involvement Questionnaire (PIQ) created and reported on by Chavkin and Williams (1987). The results ofthe surveys were used as a guide for the interview questions. An interview outline was developed based on Seidman's (1991) open-ended approach and Patton's (1980) standardized open-ended interview style in which parents and teachers were asked about their experiences and opinions on anmnber ofparent involvement issues. Parents and teachers in this school indicated agreater interest in becoming more aware ofeducational issues such as school budget and school discipline policies. Although the parents indicated agreater interest in school matters and the teachers indicated awillingness to include parents in school matters, both the parents and teachers in this study perceived the role ofthe parent as advisory, not decision making. It was concluded that to ensure ameaningful and functional role for parellts as tlleir p811icipatioll ill educational matters evolves, SCllools must have a clear vision ofthe primary goal ofall schools, namely, to foster and nourish democratic citizens for ademocratic society (Glickman, 1993). Furthennore, intentional practices such as Purkey's (ad) 5-P Relay approach, based on a democratic theory and practice of education, will have to be employed in order to give parents an authentic voice in educational matters and provide an avenue for parents to acquire the necessary skills and lmowledge needed to do so. As schools, school boards, and the Ministry ofEducation implement parent involvement guidelines and policies, developmental needs ofeach school need to be considered to ensure the employment ofdemocratic practices not authoritarian mandates. Parent interest and involvement, at whatever level, should be an important element in the overall move to make schools part ofthe democratic society they were meant to be.

Breeding parameters of great cormorants (Phalacrocorax carbo carbo) at mixed species colonies on Prince Edward Island, Canada

Breeding parameters of Great Cormorants (PkaZac/iOCOfiCLX CCUibo dCUtbo) and Double-crested Cormorants (P. CLU/uXuA CMJhLtllb) were examined at two mixed species colonies at Cape Tryon and Durell Point, Prince Edward Island from 1976 to 1978. Differential access to nests at the two colony sites resulted in more complete demographic data for P. CCUibo than for P. CLUJiituA. In 1911j P. CCtfibo was present at both colonies by 21 March, whereas P. auAAJtuA did not return until 1 April and 16 April at Cape Tryon and Durell Point, respectively. Differences in the arrival chronology by individuals of each species and differences in the time of nest site occupation according to age, are suggested as factors influencing the nest site distribution of P. CXUtbo and P. aiVtituA at Cape Tryon. Forty-eight P. dOJtbo chicks banded at the Durell Point colony between 19 74 and 19 76 returned there to nest as two- to four-year olds in 19 77 and 19 78. Unmarked individuals with clutch-starts in April were likely greater than four years old as all marked two to four-year olds (with one possible exception) in 19 77 and 1978 had clutch-starts in May and June. Seasonal variation in the breeding success of P. dOJibo individuals was examined at Durell Point in 1977. Mean clutch-size, hatching success and fledging success exhibited a seasonal decline. Four- and 5-egg clutches represented the majority (75%) of all P. CCUibo clutches at Durell Point in 1977 and had the highest reproductive success (0.48 and 0.43 chicks fledged per egg laid respectively). Smaller clutches produced small broods with significantly higher chick mortality while larger clutches suffered high egg loss prior to clutch completion.

Broad reduction and adoption in ring-billed gulls (Larus Delaworensis): the potential for inergenerational conflict

Patterns of intra-clutch egg size variation and intra-clutch hatch intervals in the Ring-billed gull (Larus delawarensis) were documented during the peak nesting period of two consecutive breeding seasons, at a colony near Port Colborne, Ontario. Egg size decreased with laying order; third laid eggs were significantly smaller than first laid eggs. Hatching of the third egg was delayed from that of first and second eggs. Intraclutch egg size differences established initial size disparities among chicks at hatch. Hatch intervals further exaggerated size disparities during the early post brood completion period. Competitive asymmetries among chicks were associated with increased mortality rates among third hatched chicks despite the lack of evidence of a sibling feeding hierarchy. Fledging success in 1987 was greater than in 1988. A "brood reduction strategy" appears to have enabled parents in 1987, to obtain an extra unit of reproductive fitness, while in 1988 parents were often unable to raise the entire brood and third chicks likely represented insurance reproductive value. Experimental broods (1988) were created in which hatch intervals were double those of natural intervals. The size disparities among chicks were significantly greater than in control broods, and the pattern of mortality among chicks suggested that first chicks benefited at a cost to second and third chicks. Parents of peak experimental broods achieved a fledging success rate similar to that of control broods. Characteristics of chick adoptions were also recorded. In each study year, 9 chicks abandoned their natal territories, 6 of which were adopted. Chicks consistently established themselves into broods where they were older than resident chicks. No direct evidence of cost to foster parents, or benefits to adopted chicks was obtained, although fledging success of adopted chicks was high.

School choice behaviour of independent school parents

One hundred and thirty-three parents of students new ~o ~ive independent schools in Ontario wer. surveyed to inve~tigate school choice behaviour. Paren~s were asKed to indicate their reasons for changing schooling, ~he criteria for selection o~ a school and the nature of the search process. Parents were also asKed to ranK speci~ic precipitants for change and criteria for choice. Spearman RanK Correla.tion tests were run comparing precipitants for change and criteria for choice for the entire sample and sub-groups based on socioeconomic status, gender of the child and family size. No signl~icant differences were found between the various $ub-groups, however, there was a strong positive correlation between precipitants for change and criteria for choice.Chi sq,uare tests were run compa.ring the number of information sources utilized in the search process, and a comparison was made between the importance of the va.rious sources of information. The majority of parents were classified as ac~ive searchers, researching one alternative more carefully than others. Socioeconomic status was the only factor to have a sign ific:ant- effect on the ranKing of information sources.

Effects of a preschool parent enrichment programme on children and their parents /

This study evaluated a preschool parent enrichment programme to assess if child and parent involvement in the programme facilitated the children's subsequent school adjustment. Also examined were the programme's effects on parent-child relationships. Participants were 56 Junior-Senior Kindergarten and Grade One students from one elementary school. Parent participants were 12 parents from the preschool parent enrichment programme, 6 parents whose children had attended other preschool programmes, and 6 parents whose children had remained at home prior to school. Five elementary teachers and both nursery school teachers from the parent enrichment programme also participated. Measures used included the Florida Key to assess children's inferred self-concept as learner and four subscales (relating, asserting, coping and investing), and interviews to assess parent and teacher perceptions. Findings indicated that there was little difference between parent and teacher perceptions about children who had attended a preschool programme. Both groups showed improved social, emotional, and behavioural skill development, together with increased self-esteem, and the ability to cope with separation from their parents. This enabled children to make the transition from preschool to primary school more successful. Children from the parent enrichment programme were not readily identifiable in terms of the profile promulgated for disadvantaged children. The Florida Key showed a main effect for the coping subscale, indicating that children from the parent enrichment programme may show more confidence in their abilities, and seek assistance from teachers than children who had no preschool experience. The parent enrichment programme appeared to have the biggest impact on the parents. Parents reported improved relationships with their children, increased confidence and self-esteem, as well as improved parenting and general life skills. The implications for short-term gains for children from this type of programme are better readiness for school, more positive self-esteem, improved social behaviour, and a higher achievement motivation. The long-term gains for children are predicted to be fewer special education placements, less grade retention, and a lower dropout rate from school. The short-term gains for parents are better social support networks," greater self-confidence, better interactions with children, and improved parenting skills. The long-term benefits may be an increased motivation to continue education, gain employment, and less family breakdown and abuse.

Problem children with and without communication delays : the changes in their parents' report of challenging behaviour, parental hassles and family conflict over a two -year period

The goal of this study was to examine the change, over a two year period, in mothers' reports of children's challenging behaviour and family conflict as they relate to change in parenting hassles (stress) among families who have preschool children with and without communication delays. Forty-four parent-child dyads participated in this Family Resource Project study that was funded by the Canadian Language and Literacy Research Network. Thirty-one ofthese families had preschool children with communication delays and 13 children were identified as not having communication delays. Child behaviour was evaluated using the Oppositional Subscale and ADHD Index of the Conners Parent Rating Scale (CPRS-R:S), the Conflict Subscale ofthe Family Environment Scale was used to examine family conflict, and the Parent Hassles Scale was used to examine parental stress. Results showed that change in mothers' daily hassles was influenced by change in their preschool children's ADHD behaviour and change in family conflict. Change in child oppositional behaviour did not predict change in mothers' hassles scores.

Ethnic Minority Parents' Involvement in Education: Exploring and Understanding Their Experiences

Lopez, Scribner and Mahitivanichcha (2001) discuss the limited volume of literature that directly addresses ethnic minority parents' involvement in their children's education and they call upon researchers to fill this gap in the literature. This study is one such positive step with its focus on exploring how ethnic minority parents of secondary school students in southern Ontario understand their involvement in their children's education. Participants in the study included three ethnic minority parents recruited from a local adult education centre, and my parents who, as ethnics minority parents, also faced challenges trying to support their children as we progressed through the Ontario educational system. Primary data were collected through in-depth, open-ended interviews approximately one hour in length. Each of the five participants was interviewed twice. Secondary data included Ontario Ministry of Education documents that addressed programs, policies, and supports for ethnic minority students in Ontario secondary schools. Fieldnotes and a research journal also provided secondary data. The findings highlight, among other things, the challenges the participants faced as ethnic minority parents with a deep desire to support their children's education, but often lacking the cultural capital valued in the Ontario school system to meet that goal. As well, I benefited greatly from this research learning about the various ways in which, in my future work as a teacher of ethnic minority students, I can integrate the knowledge, skills, and experiences of ethnic minorities into my practice to ensure that parents of the non-dominant culture have an opportunity to become highly involved in the education of their children.

A Home Literacy Handbook for Parents With Preschool Children

The purpose of this project was to provide parents with an awareness of the role that they play in their preschool children's literacy and reading development and to create a practical handbook that parents can use to teach early literacy and reading skills to their preschool children in their home environment. The handbook was created in response to the literature that confirmed that the children benefit from developing emergent literacy skills before they enter school in kindergarten or grade 1. In addition to the information gathered from the academic literature, needs assessments were conducted in order to hear perspectives from multiple stakeholders involved in the context of this project. The needs assessment questionnaires were conducted with 4 Ontario certified grade 1 and 2 teachers, and 4 parents with preschool children or children in kindergarten or grade 1. Data collected from these participants highlighted the needs of parents and were used to create a comprehensive handbook that will hopefully be accessible and useful to a wide parent audience. The results of the research project indicated that parents would, in fact, benefit from having access to a resource such as this handbook to assist in teaching the 4 components of emergent literacy to their preschool children––oral language, alphabet knowledge, phonological awareness, and print awareness––to their preschool children.
