Maltreatment of primary school students by educational staff in Israel

OBJECTIVES: This paper reports on the prevalence of emotional and physical maltreatment of students in primary schools by school staff in Israel. Victimization by staff was analyzed according to students' gender, age group (4th, 5th, and 6th grade), cultural group (Jewish-non-religious, Jewish-religious, and Arab schools), school characteristics (school size and class size), and by socio-economic status of the students' families. METHOD: Data were obtained from a nationally representative sample of 5472 students in Grades 4-6 in 71 schools across Israel. The students completed questionnaires during class, which included a scale for reporting physical and psychological maltreatment by staff. Data on the socio-economic status of the families of the students in each school were also obtained. RESULTS: Students reported generally high rates of maltreatment by staff members. Almost a third reported being emotionally maltreated by a staff member, and more than a fifth (22.2%) reported being a victim of at least one type of physical maltreatment. The most vulnerable groups for maltreatment were males, students in Arab schools, and students in schools with a high percentage of students from low-income and low-education families.CONCLUSIONS: These high rates of primary school students' victimization by staff are unacceptable. We recommend educational campaigns among teachers, as well as allocating more resources to support staff in low socio-economic neighborhoods.     

Mother-child conflict in the toddler years: lessons in emotion,morality, and relationships

Sixty-three mother-toddler dyads took part in a 6-month prospective study that examined how differences in the frequency and nature of early mother-toddler conflict related to individual differences in children's subsequent socioemotional development. When the children were 30 months, mothers and children participated in a series of laboratory tasks and in a 1.5-hr unstructured home observation. All episodes of verbal conflict between mothers and their children were identified from these sessions, transcribed, and coded for certain elements (e.g., strategy, discussion of emotion, and resolution). At 36 months, children participated in measures of emotional understanding, social competence, and early conscience development. Mothers' use of justification, resolution, and mitigation in conflict at 30 months predicted high levels of socioemotional development at age 3. These findings suggest that conflict may be an important context for children's socioemotional development.     

Potential use of cucumber (Cucumis sativus L.) endophytic fungi as seed treatment agents against root-knot nematode Meloidogyne incognita

Seed treatment with endophytic fungi has been regarded as an effective method for plant parasitic nematode control. Endophytic fungi from cucumber seedlings were isolated and screened for their potential to be used as seed treatment agents against Meloidogyne incognita. Among the 294 isolates screened, 23 significantly reduced galls formed by M. incognita in greenhouse test. The 10 most effective isolates were Fusarium (5), Trichoderma (1), Chaetomium (1), Acremonium (1), Paecilomyces (1), and Phyllosticta (1). Their control efficacies were repeatedly tested and their colonizations as well as in vitro activity against M. incognita were studied. They reduced the number of galls by 24.0%–58.4% in the first screening and 15.6%–44.3% in the repeated test, respectively. Phyllosticta Ph511 and Chaetomium Ch1001 had high colonizations on both the roots and the aboveground parts of cucumber seedlings. Fusarium isolates had colonization preference on the roots, their root colonizations ranging from 20.1% to 47.3% of the total root area. Trichoderma Tr882, Paecilomyces Pa972, and Acremonium Ac985 had low colonizations on both the roots and the aboveground parts. Acremonium Ac985, Chaetomium Ch1001, Paecilomyces Pa972, and Phyllosticta Ph511 produced compounds affecting motility of the second stage juveniles of M. incognita. Based on these results, Chaetomium Ch1001 was considered to have the highest potential as a seed treatment agent for M. incognita biocontrol.     

Hospital-based multidisciplinary teams can prevent unnecessary child abuse reports and out-of-home placements

OBJECTIVE: To determine how often and for what reasons a hospital-based multidisciplinary child abuse team concluded that a report of alleged or suspected child abuse was unnecessary in young children with fractures. METHODS: A retrospective review was completed of all children less than 12 months of age who, because of fractures, were referred to the hospital multidisciplinary child abuse team for consultation regarding the need to consider child abuse. RESULTS: The team received 99 consultations, reported 92 (93%) children as alleged or possible victims of physical abuse, and did not report 7 (7%). Age at presentation of those who were reported was 4.2 months compared to 3.0 months in the non-reported group. The average number of fractures in the reported group was 2.9 (SD 3.53) compared to 3.4 (SD 4.6) in the non-reported group. Factors that led to cases not being reported included: (a) a trauma history consistent with the fracture (n=4), (b) a diagnosis of bone fragility secondary to genetic, nutritional or medical therapy etiologies (n=2), and (c) iatrogenic fracture (n=1). CONCLUSIONS: Seven percent of the children less than 12 months of age and with at least one fracture referred to the multidisciplinary team for evaluation of possible child abuse were not reported as alleged or suspected physical abuse. The involvement of the hospital multidisciplinary child abuse team may have prevented unnecessary investigation by the county social services agency and/or police, and possible out-of-home temporary placement.

ATP and phosphocreatine utilization in single human muscle fibres during the development of maximal power output at elevated muscle temperatures

In this study, we examined the effect of muscle temperature (Tm) on adenosine triphosphate (ATP) and phosphocreatine utilization in single muscle fibres during the development of maximal power output in humans. Six male participants performed a 6-s maximal sprint on a friction-braked cycle ergometer under both normal (Tm = 34.3 degrees C, s = 0.6) and elevated (T(m) = 37.3 degrees C, s = 0.2) muscle temperature conditions. During the elevated condition, muscle temperature of the legs was raised, passively, by hot water immersion followed by wrapping in electrically heated blankets. Muscle biopsies were taken from the vastus lateralis before and immediately after exercise. Freeze-dried single fibres were dissected, characterized according to myosin heavy chain composition, and analysed for ATP and phosphocreatine content. Single fibres were classified as: type I, IIA, IIAX25 (1 - 25% IIX isoform), IIAX50 (26 - 50% IIX), IIAX75 (51 - 75% IIX), or IIAX100 (76 - 100% IIX). Maximal power output and pedal rate were both greater (P < 0.05) during the elevated condition by 258 W (s = 110) and 22 rev . min(-1) (s = 6), respectively. In both conditions, phosphocreatine content decreased significantly in all fibre types, with a greater decrease during the elevated condition in type IIA fibres (P < 0.01). Adenosine triphosphate content was also reduced to a greater (P < 0.01) extent in type IIA fibres during the elevated condition. The results of the present study indicate that after passive elevation of muscle temperature, there was a greater decrease in ATP and phosphocreatine content in type IIA fibres than in the normal trial, which contributed to the higher maximal power output.     

Mother-child discourse, attachment security, shared positive affect, and early conscience development

The separate literatures on parental discipline, maternal discourse about emotion, and autobiographical memory support the idea that parent-child discourse in the context of a supportive relationship plays a role in a child's early conscience development, and this study was designed to examine this issue. Forty-two preschool children and their mothers took part in a 45-min structured laboratory session, and at their homes, mothers completed the Attachment Q-Set. As part of the laboratory session, each mother was asked to discuss with her child one incident that occurred within the last week in which her child behaved well and one in which her child misbehaved. These conversations were transcribed verbatim and coded for maternal references to feelings, rules, consequences of the child's actions, and moral evaluatives. Each child also took part in a behavioral measure of internalization and several compliance tasks, and mothers completed a maternal report of the child's early conscience development. Consistent with attachment theory, attachment security predicted maternal and child references to feelings and moral evaluatives. Attachment security, shared positive affect between the mother and child, and maternal references to feelings and moral evaluatives also predicted specific aspects of early conscience development.     

Rearing Difficult Children: Parents' Personality and Children's Proneness to Anger as Predictors of Future Parenting

OBJECTIVE: This multi-method study of 102 mothers, fathers, and children examined children's difficult temperament as a moderator of the links between parental personality and future parenting. METHODS: Parents described themselves on the Big Five traits and Optimism. Children's difficult temperament was observed at 25 and 38 months in paradigms that assessed proneness to anger. Each parent's responsive, affectively positive parenting was observed in lengthy naturalistic interactions at 67 months. RESULTS: Regardless of child temperament, for mothers, low Neuroticism, and for fathers, high Extraversion predicted more positive parenting. For difficult, anger-prone children, mothers' low and high Optimism and fathers' low and high Openness were associated, respectively, with less or more positive parenting. CONCLUSIONS: Challenges due to children's difficult temperaments appear to amplify links between parental personality traits and parenting.     

Children's reports of emotional,physical and sexual maltreatment by educational staff in Israel

OBJECTIVES: This paper reports on the first nationally representative study on the prevalence of emotional, physical, and sexual victimization of children by school staff in Israel. The study identifies groups of children that are at higher risk for such maltreatment. We examine the differences in staff-induced victimization by the children's gender, age group (junior high vs. high school), cultural groups (Jewish non-religious, Jewish-religious and Arab schools) and by socioeconomic status of the children's families. METHOD: The study is based on a nationally representative sample of 10,410 Israeli students in Grades 7-11 in 161 schools across Israel. Students completed questionnaires during class. In addition, we obtained data on the socioeconomic status of the families of the students in each school. RESULTS: Overall, children reported high rates of victimization by staff members. Almost a quarter of all children participating in this study reported being emotionally maltreated by a staff member, almost a fifth (18.7%) reported being a victim of at least one type of physical forms of maltreatment, and 8.2% reported on at least one sexually inappropriate behavior by a staff member. The most vulnerable groups for all types of maltreatment were males, children in junior high schools, children in Arab schools, and children in schools with a high concentration of students coming from low-income and low-education families. CONCLUSIONS: The overall prevalence rates of staff maltreatment should be considered high and unacceptable. Although rates of physical and sexual maltreatment were lower than emotional maltreatment, they were still high and are worthy of greater attention. Both cultural beliefs and low family socioeconomic status increase vulnerability to staff maltreatment. We suggest conducting an educational campaign to reduce rates of staff maltreatment. We also recommend allocating more resources to support staff in low SES neighborhoods, to alleviate their stress and to provide them with the support that would reduce maltreatment of children in the educational system.
