Giant cell tumor of the second metacarpal bone
No full textthis case report discusses the reconstruction after a radical resection of a giant cell tumor in an elderly woman involving the second metacarpal bone. at the presentation the tumor was in stage iii with an involvement of the trapezium and trapezoid. the patient underwent en-block resection of the second ray including trapezium and trapezoid bones. bone fusion in opposition of the first metacarpal and a cutaneous flap was performed. this treatment allowed the patient to achieve optimal functional results with pinch and grasp ability after surgery and adequate safety from recurrency. a literature review of case series describing hand localizations of tGc, and related treatments was performed.

Bullying and Moral Disengagement in Early Adolescence: Do Personality and Family Functioning Matter?
Full text linkThe present study adopted a multi-informant approach to investigate the contribution of personality and family
functioning to moral disengagement and bullying-related behaviors in early adolescence. The sample included 102 early
adolescents (53 boys and 49 girls; mean age = 12.21 years; effect size = 0.35, power = 0.95, and error probability =
5%). Behaviors during bullying situations were detected by peer nominations. Self-report measures were administered
to assess moral disengagement and family functioning, whereas a parent-report was administered to detect personality
traits. Results showed that extraversion was positively associated with bullying and moral disengagement, while
benevolence was positively associated with defending behavior. Family functioning was negatively associated with
moral disengagement. Furthermore, we found that personality and family functioning were intertwined in their
association with bullying-related behaviors and moral disengagement. In particular, a low conscientiousness, together
with a low family functioning, decreased the likelihood of defending behavior and increased the risk of bullying. High
levels of benevolence decreased outsider behavior in students with a high family functioning. Although extraversion
was positively associated with bullying and moral disengagement, findings suggested that it increased moral
disengagement only among early adolescents with low family functioning. Overall, findings underline the importance
of addressing individual and contextual variables when studying bullying and moral disengagement among early
adolescents.

Bullying Perpetration and Victimization in Early Adolescence: Physiological Response to Social Exclusion
Full text linkThe present study investigated the associations between bullying perpetration and victimization and physiological reactivity to social exclusion. The participants were 28 early adolescents (17 boys and 11 girls; Mage= 11.55; SD = 1.34). Bullying perpetration and victimization were assessed by peer nominations. To elicit social exclusion, participants were first included and then excluded in a laboratory paradigm (Cyberball). Physiological reactivity (i.e., nose tip temperature) was detected through thermal infrared imaging during the computer simulation. Nose temperature variations during inclusion and exclusion were compared between each other. Results showed increasing skin temperature during exclusion, compared to inclusion, for the whole sample, indicating that being excluded affected physiological reactivity. However, victimization was associated with higher skin temperature during exclusion, compared to bullying. The present findings suggest the importance of combining behavioral and contact-free physiological measures when studying bullying perpetration and victimization by peers
Interactive effects of guilt and moral disengagement on bullying, defending, and outsider behavior
Full text linkWe examined the moderating effect of guilt on the associations between moral disengagement and bullying, defending and outsider behaviors in a sample of 404 students (203 boys; Mage= 11.09 years; SD = 1.48). Bullying, defending and outsider behavior were assessed through peer nominations, whereas guilt and moral disengagement were assessed by self-reports. Results showed that moral disengagement was associated with high levels of bullying and low levels of defending. Guilt was negatively associated with bullying and positively with defending. A moderating effect for guilt was also found: increasing levels of moral disengagement contributed to more bullying and outsider behavior, and to less defending, among students with low levels of guilt. The current research broadens the extant literature, showing the combined effects of guilt and moral disengagement on bullying-related behaviors
Behavioural and temperamental characteristics of children and adolescents suffering from primary headache
Full text linkTo examine indices of behavioural and emotional problems and temperamental traits in clinically referred children and adolescents suffering from tension headache or migraine. Headache in childhood and adolescence (<18 years) has been associated with the presence of behavioural and emotional difficulties, but limited data are available on the relationship between these problems and different types of headache. Clinically referred children and adolescents (N=114), 6-16 years of age, suffering from primary headache according to the diagnostic criteria of the International Headache Society, 47 with tension-type headache (TH) and 67 with migraine (M), and 36 normal controls without headache (NC) were assessed using the Parent Child Behaviour Checklist (CBCL), Children's Depression Inventory (CDI), Multidimensional Anxiety Scale for Children (MASC), Conner's Parent Rating Scale (CPRS), and Emotionality-Activity-Sociability-Shyness Scale (EAS). Psychological and personality self-rating assessments were obtained also on the children's parents and siblings. Although most headache patients had scores within the normative non-pathological range, both TH and M patients had higher CBCL total, internalizing, and externalizing scores than NC (P<0.001), and TH patients had higher scores than M patients. TH and M had higher CDI and MASC scores than NC (P<0.05), with no difference between the headache groups. TH patients had higher Emotionality and Shyness scores, and lower Sociability scores than M patients. Clinically referred children and adolescents with TH and M had higher scores of behavioural and emotional symptoms, both of internalizing and externalizing type, than normal peers. The TH group had greater psychological and temperamental difficulties than the M group

No full textPhases in the Al-Yb-Zn system between 25 and 50 at% Yb
No full textPhases YbZn1-xAlx, YbZn2-xAlx and YbZn3-xAlx were studied by electron microprobe analysis and X-ray single crystal and powder methods. The compound YbZn0.8Al0.2 crystallizes with the CsCl-type, a=3.635(2) Å. Four phases were investigated by single crystal X-ray diffraction: YbZn0.996(6)Al1.004(6), MgNi2-type, P63/mmc, a=5.573(1), c=18.051(3) Å, Z=8, wR2=0.040 and YbZn0.88(3)Al1.12(3), MgCu2-type, Fd over(3, -) m, a=7.860(2) Å, Z=8, wR2=0.060, both showing mixed Zn/Al occupancy; YbZn2.50(1)Al0.50(1), CeNi3-type, P63/mmc, a=5.496(1), c=17.336(2) Å, Z=6, wR2=0.036 and YbZn1.92(2)Al1.08(2), PuNi3- or NbBe3-type, R over(3, -) m, a=5.499(1), c=26.134(5) Å, Z=9, wR2=0.053, where the zinc atoms are ordered in the CaCu5 segment, while share the sites with aluminium in the Laves phase segment. In the pseudobinary section YbZn2-xAlx four structures occur in sequence with increasing the electron concentration: CeCu2 or KHg2 (x=0-0.3), MgZn2 (x=0.33-0.54), MgNi2 (x=0.68-1.01) and MgCu2 (x=1.12-2). This sequence agrees with the results of first-principles calculations, already reported in the literature for other similar series. In the YbZn3-xAlx section CeNi3-type compounds occur with x=0.40-0.88 followed by PuNi3-type compounds with x=0.92-1.10. The stability ranges of these phases are related to the valence electron concentration
Concepts: stored or created?
No full textAre concepts stable entities, unchanged from context to context? Or rather are they context-dependent structures, created on the fly? We argue that this does not constitute a genuine dilemma. Our main thesis is that the more a pattern of features is general and shared, the more it qualifies as a concept. Contextualists have not shown that conceptual structures lack a stable, general core, acting as an attractor on idiosyncratic information. What they have done instead is to give a contribution to the comprehension of how conceptual structure organized around such a stable core can produce contextually appropriate representations on demand. © 2010 Springer Science+Business Media B.V
