AbstractThis study’s objective is to analyze temperament and parenting variables as they relate to proactive and reactive aggression in children. To be specific, profiles based on these variables were analyzed in children with high levels of proactive versus reactive aggression. The sample was made up of two groups: 482 children (52.3% boys) between 1 and 3 years-old, and 422 children (42.42% boys) 3 to 6 years-old. Statistical analyses of the two age groups included: Pearson´s correlations to explore the relationships among variables, Cluster Analysis to create groups with different levels of aggression, and finally discriminant analysis to determine which variables discriminate between groups. The results show that high levels of frustration/negative affect in the 1–3 year-old group and low effortful control in children 3 to 6 years old are the most relevant variables in differentiating between aggressive and non-aggressive subjects. Nevertheless, differential profiles of subjects with high levels of proactive versus reactive aggression were not observed. The implications of these different types of aggression in terms of development and prevention are discussed.

Bovine herpesvirus type 5 (BoHV-5) is a major cause of viral meningoencephalitis in cattle. The expression of different viral proteins has been associated with BoHV-5 neuropathogenesis. Among these, gI, gE and US9 have been considered essential for the production of neurological disease in infected animals. To evaluate the role of gI, gE and US9 in neurovirulence, a recombinant from which the respective genes were deleted (BoHV-5 gI-/gE-/US9-) was constructed and inoculated in rabbits of two age groups (four and eight weeks-old). When the recombinant virus was inoculated through the paranasal sinuses of four weeks-old rabbits, neurological disease was observed and death was the outcome in 4 out of 13 (30.7 %) animals, whereas clinical signs and death were observed in 11/13 (84.6%) of rabbits infected with the parental virus. In eight weeks-old rabbits, the BoHV-5 gI-/gE-/US9- did not induce clinically apparent disease and could not be reactivated after dexamethasone administration, whereas wild type BoHV-5 caused disease in 55.5% of the animals and was reactivated. These findings reveal that the simultaneous deletion of gI, gE and US9 genes did reduce but did not completely abolish the neurovirulence of BoHV-5 in rabbits, indicating that other viral genes may also play a role in the induction of neurological disease.

Concentrating on the role of supply chain decoupling point, this chapter introduces different levels of customisation and mass operations and three types of mass customisation. It argues that in each mass customisation type, information systems which are upstream and downstream of the decoupling point can be varied. Consequently, information flows in different types of mass customisation have been examined. This analysis is an endeavour to organise mass customisation information systems across the supply chain, while it can be a useful structure for future researches in this area as well.

Affect impacts people’s cognitive processes as well as provides the energy to pursue goals and engage in actions. Research suggests that affect might influence instrumental learning behavior. This review aims to summarize the existing literature concerning the relationship between affect and instrumental practice. In order to determine the role of affect in undertaking instrumental practice and in engagement in practice, we conducted a systematic search via electronic databases and reference lists; we also hand-searched the key journals. Studies were included in the review if they concerned both affect and practicing behavior in musicians and instrumental students across all age groups and if the relationships between the two constructs were investigated. We focused on individual instrumental practice in the classical repertoire. Eleven studies met our inclusion criteria. They reported quantitative relationships between affect and the amount of practice or qualitatively described the role of affect in practice engagement. The results of this systematic review show that practicing a musical instrument is associated with different types of affect—practice-related, performance-related, and context-free affect. Further investigation of affect in the context of music learning may inform future interventions for instrumentalists motivating them to practice.

Forest sites are formed in the interaction of heterogeneous components of biogeosystem. The increase or decrease of biological component in forest biogeosystems defines the different types of strategy with opposite characteristics, representing the different lines of adaptation (to the biological medium and abiotic environment). The manifestation of adaptive strategy requires appropriate tools, which are evolving on the basis of accumulated property (information capacity) and prevailing forest sites. Forest sites can be seen as an external “order” on the evolution of adaptations. Silvicultural properties of forest biological systems work enough in the interaction of different forms of matter (biological, abiotic), mapping out a hierarchy of biogeosystems. The information potential of forest biota interconnects different levels of systemic organization of forest biogeosystems. Further development of biogeocenology and the theory and ecosystems will allow to investigate the relationship of forest biota with exogenous forest-forming factors.

Background: Rupture of aneurysm is a vascular events, it is assumed that season exerts an influence in the incidence of rupture of aneurysm. But seasonal variation on the aneurismal subarachnoid hemorrhage (ASAH) is a subject of controversy. Some previous studies reported that changes in the biometric pressure in different season modulate the occurrence of vascular events. Aims: To evaluate the role of seasons of a year on the onset of aneurismal subarachnoid hemorrhage (ASAH). Methodology: This is a retrospective study. There were 377 patients with definite diagnosis of ASAH. Patients were evaluated in two age groups of >60 and less than 60. Results: The frequency of ASAH in winter and autumn was 55.4% and spring and summer was 44.6%% respectively. This difference was statistically significant (p>o.o5). The effect of hypertension and diabetes mellitus revealed no influence on subarachnoid hemorrhage (SAH) in our study. Conclusion: There was influence of seasonal variation on the onset of ASAH and which was predominantly during winter and autumn. Bangladesh Journal of Neuroscience 2013; Vol. 29 (1) : 15-17

In this study, we focus on the usability of pseudo-3D thematic maps (static perspective views) compared with their conventional 2D equivalents. A total of 105 study participants were divided into two groups (12–19 years old and 20–27 years old). A Perspective Taking Test measured their spatial abilities and each participant solved 15 tasks using four thematic maps. We compared map variants to determine which is more suitable for individual tasks. We then examined the differences between the two age groups and tried to find any relationship between the user’s spatial abilities and the number of correct answers. We observed a significant difference regarding the map’s visualization dimension only in one particular task and significant differences between the age groups when they worked with 2D maps. We found a positive correlation between the participant’s level of spatial ability and the number of correct answers.

This article develops a theoretical framework for analyzing the role of kinship in entrepreneurship. Kinship, we argue, is a key ingredient of the social and cultural environment of entrepreneurs, and, therefore, essential in understanding how and why entrepreneurship happens. Building on qualitative research conducted among Cambodian Chinese entrepreneurs in Phnom Penh, we define kinship as interpersonal ties grounded in relatedness. We distinguish different categories of kinship ties that involve different levels of relatedness and are used for different aspects of entrepreneurship, and we identify different types of reciprocity and trust as the sociocultural dynamics that buttress kinship involvement in entrepreneurship.

Abstract Tardigrades may be divided into the following feeding groups: herbivores, carnivores and omnivores. However, little is known about their specific feeding preferences. Here, we used a number of laboratory experiments with 18 potential food sources, representing a wide variety of organisms, to test feeding preferences, survival and fecundity of three tardigrade species, representing different feeding modes. We also tested for differences in preferences between juveniles and adults, and differences in survival between two age groups: one that started the experiment as juveniles and the other as adults. In our experiments, Milnesium inceptum is confirmed to be a carnivore, being able to reproduce only on animal prey. We also show that Hypsibius exemplaris is a herbivore, feeding on cyanobacteria, algae and fungi. Paramacrobiotus fairbanksi, on the other hand, is demonstrated to be an omnivore, feeding on cyanobacteria, algae, fungi and animals. In some cases, juveniles preferred different types of food than adults. Reproduction was strongly affected by food type. Finally, we demonstrate that tardigrades may ingest food types that they are not able to digest. Thus, gut content analysis may be misleading as a method of studying tardigrade feeding habits.

The present study evaluates the role of age on the rate of acquiring English as a second language in an immersion setting. Subjects were children with native languages typologically very different from English. The children arrived in the United States between the ages of 7 and 12 years and were tested on their knowledge of English grammatical morphology and syntax at different lengths of stay in the United States, ranging from 6 months to 3 years. Subjects' performance was predicted by the length of their stay in the United States and by gender, with females outperforming males. Age of arrival played no role in predicting subjects' rate of acquisition. Performance was very similar between two age groups examined (7–9– and 10–12-year-old arrivals) throughout the 3 years measured. The present results suggest that, on certain aspects of grammar, different-aged children acquire a second language during the first 3 years of acquisition at similar rates when their native language is very different in typology from the target language.

AbstractBackground:Vestibular schwannomas in younger patients have been observed to be larger in size and grow more quickly.Objective:This study aimed to evaluate the expression of three important cell cycle proteins, cyclin D1, cyclin D3and Ki-67, in vestibular schwannoma patients separated into two age groups: ≤40 years or >40 years.Method:Immunohistochemical detection of cyclin D1, cyclin D3and Ki-67 was undertaken in 180 surgically resected vestibular schwannomas.Results:The proliferation index of vestibular schwannomas was statistically higher in the ≤40 years age group compared to that in the >40 years age group (mean of 4.52vs3.27, respectively;p = 0.01). Overexpression of cyclin D1and cyclin D3was found in 68 per cent and 44 per cent of tumours, respectively.Conclusion:There was an increased Ki-67 proliferation index in the younger age group that appears to correlate with clinical behaviour. Vestibular schwannomas in both age groups show increased expression of cyclin D1and cyclin D3.
