We have developed a wet lab DNA microarray simulation as part of a complete DNA microarray module for high school students. The wet lab simulation has been field tested with high school students in Illinois and Maryland as well as in workshops with high school teachers from across the nation. Instead of using DNA, our simulation is based on pH indicators, which offer many ideal teaching characteristics. The simulation requires no specialized equipment, is very inexpensive, is very reliable, and takes very little preparation time. Student and teacher assessment data indicate the simulation is popular with both groups, and students show significant learning gains. We include many resources with this publication, including all prelab introductory materials (e.g., a paper microarray activity), the student handouts, teachers notes, and pre- and postassessment tools. We did not test the simulation on other student populations, but based on teacher feedback, the simulation also may fit well in community college and in introductory and nonmajors' college biology curricula. 相似文献

This paper addresses the developmental nature of sexually abusive behaviors as they apply to juvenile male sexual offenders. Socialization and sexual victimization are discussed. Three case histories elucidate and support the discussion of the development of victim offending. Significant treatment issues of juvenile male sexual offenders center around the sexual assault cycle which provides a framework for sexual offenders to conceptualize and understand the cognitive, behavioral, psychological, and situational factors which have resulted in their offense(s). Although sexual offenders and sexual offenses are each unique, the sexual assault cycle offers a means of addressing essential commonalities in the treatment of juvenile sexual offenders. Sexual offender specific treatment is viewed as essential for decreasing the risk of further sexual offenses, and thus decreasing the incidence of sexual victimization. 相似文献

Youth on the street: Abuse and neglect in the eighties 总被引:2,自引:0,他引:2
This paper discusses the findings of a study of runaways and homeless youth who were interviewed on the street the last week of every month on five week nights from late afternoon until 2 a.m. over a period of one year. The data derived from 489 interviews provided some interesting insights. Two distinct groups emerged from the analysis, generating a tentative hypothesis that the true "runners" tend to leave their homes with the intention of not returning and thus their runs are extended; the second group, designated "in and outers," use the run as a temporary coping mechanism. Their runs tend to be impulsive and of short duration. The study found that runaways (in particular the runners) are at great risk of being drawn into illegal activities. Major factors affecting this risk are distance from home and length of time on the run. A significant proportion of the youth interviewed had run from substitute care arrangements, and a disturbing implication emerging from the research is that adolescents in our society suffer from systemic abuse and neglect. One outcome of this piece of research was the opening of a safe house for early runners in January 1987. The operation of the house includes careful compilation of data to further advance understanding of the runaway population and its needs. 相似文献

While many child maltreatment victims suffer serious negative emotional sequelae, others do surprisingly well. Resilience in children is a relative concept which can change over time and is affected by environment and genetics. Resilience is fostered by protective factors which ameliorate or alter a child's response to the hazards of maltreatment that usually predispose to maladaptive outcome. Personal characteristics or skills that may foster resilience include (1) rapid responsivity to danger; (2) precocious maturity; (3) dissociation of affect; (4) information seeking; (5) formation and utilization of relationships for survival; (6) positive projective anticipation; (7) decisive risk taking; (8) the conviction of being loved; (9) idealization of an aggressor's competence; (10) cognitive restructuring of painful experiences; (11) altruism; and (12) optimism and hope. There are also generic life circumstances, such as having access to good health, educational, and social welfare services, that foster resilience in children regardless of the specific nature of the stressor. Additionally, there may be abuse-specific protective factors in the environment. Examples might include the quick and full acknowledgment of an offender regarding abuse, or timeliness and permanence of legal actions affecting a child's custody. The life stories of three well-known survivors of various forms of child maltreatment illustrate how protective factors contribute to resilience. A caution is noted regarding how personal characteristics developed for survival may become maladaptive if overused and/or not given up when the stressor no longer exists. Characterological problems are most likely to develop when a child's life circumstances fail to change and the environment never becomes secure. 相似文献

Increased awareness of the problem of child sexual abuse has resulted in increasing numbers of children presenting to professionals for the evaluation of possible sexual victimization. A multidisciplinary project to develop professionals' knowledge and skills in the identification and evaluation of possible victims is described. The program focused on the child as a victim and emphasized developmental perspectives with regard to identification, interviewing children, the medical examination, and children in the legal system. Fifty-one medical and social work professionals from ten Indiana counties attended the program and responded to questionnaires about their experience and knowledge. Of 40 (78%) respondents, 63% had had no previous training in the medical evaluation for child sexual abuse. Child protective workers referred alleged victims primarily to the child's regular physician (37%) or emergency room (31%) for medical examination. Knowledge about child sexual abuse improved significantly at two weeks postsymposium (p = .001) and remained improved at six months postsymposium (p less than .02). These original participants have subsequently organized similar multidisciplinary programs in their local communities for medical, social, law enforcement, and legal professionals; thus, they have been "seeds" for further educational and cooperative efforts throughout the state. 相似文献

Intake interviews were analyzed from 365 adults molested as children (AMACs). The AMACs were entering treatment at the Child Sexual Abuse Treatment Program (San Jose, CA). This study presents data on the relationship of the perpetrator to the victim, and whether most molestations include intercourse. The majority of the perpetrators (62%) were either biological fathers or father-surrogates. Ninety-nine percent of the perpetrators were known to the victim; 97% were male. As in past studies, fondling from the waist down was the most common type of molestation, occurring in 92% of the cases. Forty-four percent of cases included intercourse. The present findings are compared with past research and are discussed in the context of common misconceptions associated with child sexual abuse. 相似文献

This study examines the linguistic and cultural intersections of recently arrived Somali Bantu refugee students in South Texas through the lens of border theory. The use of Spanish in the homes of refugee families is explored in addition to ways in which an educator used testimonios to honor students’ migration experiences. Findings show how specific approaches used in schools that affirm both the receiving communities’ and the new arrivals' local knowledge can have a lasting impact on literacy acquisition and resettlement experiences. Findings from this study also illuminate the potential impact of educators who develop a critical, inquiry stance by embedding multiple entry points for students to cross social, cultural, linguistic, and curricular borders in school. 相似文献

English-Spanish cognates are an important subset of words in both the English and Spanish languages. Cognates are words that possess identical or nearly identical spellings and meanings in both languages as a result of being derived from Latin and Greek. Of major importance is the fact that many of the more than 20,000 cognates in English are academic vocabulary words, terms essential for comprehending school texts.?The Pura Belpré Children's Book Award has been given since 1996 to outstanding children's and young adult literature that represents, affirms, and celebrates the Latino cultural experience. The books are judged for their literary and artistic quality.?There are many English-Spanish cognates in each of the Pura Belpré picture books. The purpose of this article is to introduce the Pura Belpré Cognate Database, which lists all of the English-Spanish cognates for each of the children's picture books that have won the award or have been designated as honor books. Ideas for vocabulary, spelling, and morphology lessons or mini-lessons are also presented. 相似文献

The teacher readaloud is an instructional tool established in its ability to foster children's language and literacy development. Increasing cultural and linguistic diversity and changing standards place pressure on teachers to provide literacy and language instruction relevant to children's everyday lives and learning. This article presents a framework for conducting culturally and linguistically relevant readalouds within two essential components, talk and text, in terms of developing cultural competence, maintaining high academic expectations, and fostering a critical stance. Particular attention is given to the interactive nature of these readalouds and how they can be used to promote children's active co-construction of textually-based meaning. 相似文献
