Published: November 2013

AbstractLet $G$ be a finite group. A subgroup $H$ of $G$ is said to be $E$-supplemented in $G$ if there is a subgroup $T$ of $G$ such that $G= HT$ and $H\cap T\leq {H}_{eG} $, where ${H}_{eG} $ denotes the subgroup of $H$ generated by all those subgroups of $H$ which are $S$-quasinormally embedded in $G$. In this paper, some new characterisations of $p$-supersolubility of finite groups are given under the assumption that some primary subgroups are $E$-supplemented.

The aim of the present study was to evaluate the impact of infant breast-feeding on cardiovascular risk in young adults. This unique study group involved 158 subjects (eighty-two females) originally collected prospectively at birth in 1975 and followed up to the age of 32 years. Frequent visits during the first year guaranteed the knowledge of the precise duration of breast-feeding. All infants received at least some breast milk. Participants were assessed for both individual cardiovascular risk factors (blood pressure, plasma lipids, homeostatic model assessment of insulin resistance and waist circumference) and the general clinical risk of cardiovascular events by calculating the Framingham risk score (FRS) and the metabolic syndrome criteria score (NCEP-ATPIII; National Cholesterol Education Program's Adult Treatment Panel III). Data on lifestyle factors were carefully collected. Linear regression analyses revealed that the effect of the duration of breast-feeding was not relevant (0·02 decrease in the FRS per one additional breast-feeding month; 95 % CI − 0·19, 0·09). Similarly, the effect of breast-feeding was minor on all of the individual cardiovascular risk factors. We used sex, physical activity, dietary fat and vitamin C, smoking and alcohol consumption as covariates. Again, logistic regression analyses detected no significant impact of the duration of breast-feeding on the risk of the metabolic syndrome according to the NCEP-ATPIII (OR 0·95, 95 % CI 0·8, 1·1). The strongest independent predictor for later CVD risk was male sex. In conclusion, in this prospectively followed cohort of young adults born at term and at weight appropriate for gestational age, the duration of breast-feeding did not have an impact on the accumulation of cardiovascular risk factors.

AbstractPlutella xylostella(L.) is the most important pest of Brassicaceae worldwide, with a recent estimate of US$ 4–5 billion expenditure for the control of this insect. A case of very high resistance of this pest to chlorantraniliprole was recently associated with reduced efficacy in a Brazilian field ofBrassicaspp. Although diamide resistance has been characterized, the fitness of insects due to such resistance has yet to be examined. Therefore, in this study, biological parameters were assessed in both susceptible and resistant strains ofP. xylostellasubjected to sublethal chlorantraniliprole concentrations. The field strain showed high resistance to chlorantraniliprole (RR50=27,793-fold), although resistance rapidly decreased in the first generations, showing instability. The exposure of susceptible and resistant larvae to their respective LC1, LC10, and LC25values led to an increased duration of the larval and pupae phases and reduced weight in both strains; however, no significant differences in pupal viability across the treatments were observed. The resistant insects presented significantly lower larval weight and fecundity and higher larval and pupal periods, hatchability, and male longevity when not exposed to chlorantraniliprole, suggesting a fitness cost associated with resistance. In addition, resistant females showed a significantly higher egg-laying period and longevity at LC25, whereas the males lived longer at LC1. Chlorantraniliprole negatively impacted the biological parameters of both strains tested, although these effects were more relevant to the resistant insects. ResistantP. xylostellashowed negative and positive biological trade-offs when compared with the susceptible individuals in both the absence and presence of chlorantraniliprole. Despite the important role that these trade-offs may play in the evolution of resistance to chlorantraniliprole, practical applications still depend on such information as the dominance of fitness costs and resistance.
THEOPHRASTUS ON PLATONIC AND ‘PYTHAGOREAN’ IMITATION
Authors: Horky Phillip Sidney 
Published: November 2013

In the twenty-fourth aporia of Theophrastus'Metaphysics, there appears an important, if ‘bafflingly elliptical’, ascription to Plato and the ‘Pythagoreans’ of a theory of reduction to the first principles via ‘imitation’ (μίμησις):Πλάτων δὲ καὶ οἱ Πυθαγόρειοι μακρὰν τὴν ἀπόστασιν, ἐπιμιμεῖσθαι τ' ἐθέλειν ἅπαντα· καίτοι καθάπερ ἀντίθεσιν τινα ποιοῦσιν τῆς ἀορίστου δυάδος καὶ τοῦ ἑνός, ἐν ᾗ καὶ τὸ ἄπειρον καὶ τὸ ἄτακτον καὶ ὡς εἰπεῖν πᾶσα ἀμορφία καθ' αὑτήν, ὅλως δ' οὐχ οἷον τ' ἄνευ ταύτης τὴν τοὺ ὅλου φύσιν, ἀλλ' οἷον ἰσομοιρεῖν ἢ καὶ ὑπερέχειν τῆς ἐτέρας, ᾗ καὶ τὰς ἀρχὰς ἐναντίας. Διὸ καὶ οὐδὲ τὸν θεόν, ὅσοι τῷ θεῷ τὴν αἰτίαν ἀνάπτουσιν, δύνασθαι πάντ' εἰς τὸ ἄριστον ἄγειν, ἀλλ' εἴπερ, ἐφ' ὅσον ἐνδέχεται· τάχα δ' οὐδ' ἂν προέλοιτ', εἴπερ ἀναιρεῖσθαι συμβήσεται τὴν ὅλην οὐσίαν ἐξ ἐναντίων γε καὶ ἐν ἐναντίοις οὖσαν.(Theophrastus,Metaphysics, 11a26–b12)Plato and the Pythagoreans make the distance [between the first principles and everything else] a great one, and they make all things desire to imitate fully; and yet, they set up a certain opposition, as it were, between the Indefinite Dyad and the One. In the former [resides] the Unlimited and the Unordered and, as it were, all Shapelessness as such; and they make it altogether impossible for the nature of the universe to exist without this [that is, the Indefinite Dyad] – it [that is, the Indefinite Dyad] could only have an equal share in things, or even exceed the other [first principle, that is, the One] – whereby they also make their first principles contrary [to one another]. Therefore, those who ascribe causation to the god claim that not even the god is able to reduce all things to the best, but, even if at all, only in so far as is possible. And perhaps he wouldn't even choose to, if indeed it were to result in the destruction of all existence, given that it [that is, existence] is constituted from contraries and consists of contraries.

For much of the Greek (and Roman) world, education was based on the Homeric epics, and thus Epicurus' statement represents a complicated position towards Homer in particular and poetry in general. Epicurean philosophy rejects poetry because it is misleading about the gods and the nature of the soul, but Epicurus and his followers, most notably Philodemus and Lucretius, engage in poetic allusion and even the composition of poetry. Much work has been done on allusions to poetry in all three writers, but I hope here to bring out a heretofore unnoticed poetic allusion at the start ofDe rerum naturaBook 2, in which Lucretius makes a programmatic statement about not only his philosophy, but also his poetry and its place in the poetic tradition.
Effects of disturbance and altitude on soil seed banks of tropical montane forests

Published: November 2013

Abstract:Vast areas of tropical forests have been deforested by human activities, resulting in landscapes comprising forest fragments in matrices of deforested habitats. Soil seed banks (SSB) are essential sources for the regeneration of tropical forests after disturbance. In a fragmented montane landscape in the Bolivian Andes, we investigated SSB in three different habitat types that were associated with different degrees of disturbance, i.e. in forest interior, at forest edges and in deforested habitats. Sampling of habitats was replicated at six sites ranging in altitude from 1950 to 2450 m asl. We extracted seeds from dried soil samples by sieving, classified seeds into morphospecies and size classes, and characterized SSB in terms of density, species richness and composition. We tested effects of disturbance (i.e. habitat type) and altitude on SSB characteristics. Overall, small seeds (<1 mm) dominated SSB (81% of sampled seeds). Seed density and species richness were lowest in deforested habitats, especially in large seeds and distant from adjacent forests (≥20 m), while small-seeded species were most numerous near forest margins. Species turnover between habitats was high. Altitude altered the composition of SSB, but had no effects on seed density and species richness. We conclude that the potential of SSB for natural regeneration of deforested habitats is low and decreases with increasing distance from forest remnants and that forest edges may be eventually invaded by small-seeded species from deforested habitats.
Variation in savanna vegetation on termite mounds in north-eastern Namibia
Authors: Yamashina Chisato 
Published: November 2013

Abstract:In savanna, termite mounds support more diverse vegetation than off-mound areas, but little is known of the patterns in plant assemblages on mounds. To explain vegetation differentiation between (1) component structures of termite mounds (conical centre vs. pediment), (2) active and inactive mounds (termites present vs. termites absent), and (3) sites on and off mounds (on mounds vs. surrounding savanna), species composition, richness and abundances of woody plants were recorded on 70 mounds and in 13 savanna plots (each 20 × 20 m) in north-eastern Namibia, focusing on soil hardness, mound status (active or not) and mound micro-topography as explanatory factors. Woody plants were absent from 33% of active mounds (54% of active cones) but were absent from only 5% of inactive mounds. Species richness and abundance per mound (mean ± SD) were lower on active mounds with (2.0 ± 1.8 and 4.6 ± 6.6, respectively) and without pediments (0.6 ± 0.6 and 0.9 ± 1.1, respectively) than on inactive mounds (4.4 ± 2.7, 19.4 ± 18.8, respectively). Despite the lower woody plant cover, some characteristic species, such as Salvadora persica, occurred preferentially on active mounds; this species occurred on 42% of active mounds. Mean soil hardness (± SD) was higher on conical parts of active mounds (4300 ± 2620 kPa) than on adjacent pediments (583 ± 328 kPa) and inactive mounds (725 ± 619 kPa). This study suggested that mound status, mound micro-topography, and soil hardness promote variability in the vegetation on mounds.
Under the UN Security Council's Watchful Eyes: Military Intervention by Invitation in the Malian Conflict
Authors: BANNELIER KARINE , CHRISTAKIS THEODORE 
Published: November 2013

AbstractResponding to an urgent request by the authorities of Mali, France launched Operation Serval against several terrorist armed groups in January 2013. The French troops were assisted by a Chadian contingent and by forces progressively deployed by other African countries within a UNSC authorized African force (Resolution 2085). While the French and African military operations in Mali were clearly legal, they raise important questions ofjus ad bellumin relation to the two legal arguments put forward to justify them: intervention by invitation, and UNSC authorization. In this paper we first discuss the general rules of international law applying to intervention by invitation. We explain that such an intervention could sometimes be contrary to the principle of self-determination and we propose a purpose-based approach. We then apply these rules to the situation in Mali and conclude that the French and Chadian interventions were legal because, on the one hand, the request was validly formulated by the internationally recognized government of Mali and, on the other hand, their legitimate purpose was to fight terrorism. The UNSC approved this legal basis and ‘helped’ France and Chad appeal validly to it by listing the enemy as ‘terrorist groups’. It gave its ‘blessing’ to these interventions, without authorizing them, and observed the events with relief. The adoption of Resolution 2100 on 25 April 2013 raises new legal questions. The Council creates a UN peace enforcement mission in Mali, MINUSMA, which has a robust use-of-force mandate. Created just a few weeks after the DRC Intervention Brigade, this force seems to indicate an ongoing evolution (revolution?) in UN peacekeeping, notwithstanding the assurances by some UNSC member states that MINUSMA will avoid ‘offensive counter-terrorism operations’. At the same time Resolution 2100 gives a restricted use-of-force mandate to France (to protect MINUSMA), without challenging the legal validity of intervention by invitation for all other tasks. The conflict in Mali might thus remain for some time yet between the latitude of UNSC authorization and the longitude of unilateral intervention by invitation.
The Admissibility and Weight of Written Witness Testimony in International Criminal Law: A Socio-Legal Analysis
Authors: MCDERMOTT YVONNE 
Published: November 2013

AbstractThis article introduces some quantitative and qualitative analysis on the use of written witness statements in lieu of oral testimony at trial to assess in practice the impact of the rules on the admissibility of written witness testimony before the International Criminal Tribunal for the Former Yugoslavia, the International Criminal Tribunal for Rwanda, and the Special Court for Sierra Leone. It traces pieces of evidence admitted under the newer, more liberal, rules on written witness testimony from admissibility to judgment, to establish what impact, if any, these rules have had in practice and whether the critique that such rules might jeopardize fair-trial standards has been realized. The analysis illustrates that the newer rules on admissibility are used with relative infrequency in some tribunals, but that the admission of such statements could raise the question of equality of arms in others, given that the more liberal rules on written statements tend to be used more frequently by the prosecution than by the defence. It will be shown that some chambers have continued to emphasize the importance of oral testimony and have taken a very cautious approach when weighing written testimony, whilst others have suggested that written testimony that was not subject to full cross-examination should not, in principle, be given less weight than oral testimony. The ‘totality of the evidence’ approach in weighing the evidence will be analysed from a practical standpoint, and it will be shown that recent Appeals Chamber jurisprudence suggests that trial chambers may need to take a more particularized approach to pieces of evidence in the future.

AbstractChildren in foster care have often encountered a range of adverse experiences, including neglectful and/or abusive care and multiple caregiver transitions. Prior research findings suggest that such experiences negatively affect inhibitory control and the underlying neural circuitry. In the current study, event-related functional magnetic resonance imaging was employed during a go/no go task that assesses inhibitory control to compare the behavioral performance and brain activation of foster children and nonmaltreated children. The sample included two groups of 9- to 12-year-old children: 11 maltreated foster children and 11 nonmaltreated children living with their biological parents. There were no significant group differences on behavioral performance on the task. In contrast, patterns of brain activation differed by group. The nonmaltreated children demonstrated stronger activation than did the foster children across several regions, including the right anterior cingulate cortex, the middle frontal gyrus, and the right lingual gyrus, during correct no go trials, whereas the foster children displayed stronger activation than the nonmaltreated children in the left inferior parietal lobule and the right superior occipital cortex, including the lingual gyrus and cuneus, during incorrect no go trials. These results provide preliminary evidence that the early adversity experienced by foster children impacts the neural substrates of inhibitory control.

AbstractThis study examined the psychometric properties of the DSM-oriented scales of the Child Behavior Checklist (Achenbach, Dumenci, & Rescorla, 2003) using confirmatory factor analysis to compare the six-factor structure of the DSM-oriented scales to competing models consistent with developmental theories of symptom differentiation. We tested these models on both clinic-referred (N = 757) and school-based, nonreferred (N = 713) samples of youths in order to assess the generalizability of the factorial structures. Although previous research has supported the fit of the six-factor DSM-oriented structure in a normative sample of youths ages 7 to 18 (Achenbach & Rescorla, 2001), tripartite model research indicates that anxiety and depressive symptomology are less differentiated among children compared to adolescents (Jacques & Mash, 2004). We thus examined the relative fit of a six- and a five-factor model (collapsing anxiety and depression) with younger (ages 7–10) and older (ages 11–18) youth subsamples. The results revealed that the six-factor model fit the best in all samples except among younger nonclinical children. The results extended the generalizability of the rationally derived six-factor structure of the DSM-oriented scales to clinic-referred youths and provided further support to the notion that younger children in nonclinical samples exhibit less differentiated symptoms of anxiety and depression.
Interaction matters: Quantifying Conduct Problem × Depressive Symptoms interaction and its association with adolescent alcohol, cigarette, and marijuana use in a national sample
Authors: Maslowsky Julie , Schulenberg John E. 
Published: November 2013

AbstractSubstance use is a major contributor to morbidity and mortality among American adolescents. Conduct problems and depressive symptoms have each been found to be associated with adolescent substance use. Although they are highly comorbid, the role of the interaction of conduct problems and depressive symptoms in substance use is not clear. In national samples of 8th-, 10th-, and 12th-grade students from the Monitoring the Future study, latent moderated structural equation modeling was used to estimate the association of conduct problems, depressive symptoms, and their interaction to the use of alcohol (including binge drinking), cigarettes, and marijuana. Moderation by age and sex was tested. The interaction of conduct problems with depressive symptoms was a strong predictor of substance use, particularly among younger adolescents. With few exceptions, adolescents with high levels of both conduct problems and depressive symptoms used substances most frequently. Conduct problems were a strong positive predictor of substance use, and depressive symptoms were a weak positive predictor. Whereas conduct problems are often thought to be a primary predictor of substance use, this study revealed that depressive symptoms potentiate the relation of conduct problems to substance use. Therefore, substance use prevention efforts should target both depressive symptoms and conduct problems.
