The following document was created in order to promote intonation consensus in ensembles and to better facilitate learning in educational settings. Non-keyboard instruments provide musicians an opportunity to make nearly infinitesimal adjustments to pitch while performing; this creates difficulties for students and challenges even the most seasoned professionals. Non-keyboard musicians struggle their whole lives to play in tune, and even when one knows exactly where they want to place a pitch, technical difficulties can foul any musician's performance. When performing solo, the musician must choose a tuning system that is suitable for the music being performed, and attempt to realize it. When performing in ensembles, the need for consensus and a systematic approach become more apparent. When performing with keyboards, the difficulties are increased as further compromises are required. This research was conducted with the intention to assist non-keyboard instrumentalists in selecting and recreating an appropriate temperament. Additionally, the author hopes that keyboard instrumentalists will be inclined to make a consideration for the non-keyboard instruments when selecting their temperament. The following document contains information useful to those wishing to employ a consistent approach to tuning. Presented here are the acoustic phenomena that have perplexed scholars around the world for the last 2600 years. The history and science of these acoustic questions will be demonstrated and discussed.

Temperamental characteristics may distinguish which children are at greater risk for later psychopathology. In addition, parenting quality may interact with the association between temperament and behavior problems to increase or decrease externalizing or internalizing behaviors in children. This study examined whether mothers’ parenting quality moderated the associations between children’s temperamental fear and children’s behavior problems. The sample consisted of 143 low-income mother-child dyads who participated in various interactional tasks designed to measure mothers’ parenting and children’s temperamental fear. While children’s fearless and fearful temperament were not significantly associated with externalizing and internalizing behaviors, respectively, some significant associations emerged. Positive and negative parenting were negatively associated, negative parenting and fearful temperament were positively associated, fearful and fearless temperament were negatively associated, and internalizing and externalizing behaviors were positively associated. Finally, results from moderation analyses indicated no significant interaction effects of parenting quality and children’s temperamental fear on children’s problem behavior.

Ongoing investigations of drunken aggression tend to focus on 1) situational cues, and 2) individual variables such as personality traits. This study investigated the hypothesis that an undergraduates attention would be pulled toward a nonconscious presentation of aggression stimuli, especially in the presence of alcohol cues, and especially if he or she was high on trait anger [as measured using the State Trait Anger Expression Inventory (STAXI); Spielberger, 1988] and had high expectancies for behaving aggressively while drinking alcohol [as measured using the Expectancy Questionnaire for Alcohol and Aggression Lo Dose (EQAAL); Epps, Hunter, LeVasseur, Steinberg, and Hancock, unpublished manuscript]. Seventy-nine of the participants who completed questionnaires also completed one of the two computer tasks (adapted from John Bargh and associates) weeks later in either the Barroom or the Cleanroom. Attention to HiAggression words (as measured by reaction time or error rate difference scores) was significantly higher than attention to NonAggression words using the parafoveal visual task, with observed power at 1. No significant differences were found using the dichotic listening task. Additionally, there was a significant three-way interaction (Word Type X Setting X Angry Temperament) when participants where blocked according to high vs. low angry temperament scores. Follow-up analyses as well as regression analyses for the specific hypothesis provided mixed results. Individuals lower on angry temperament tended to demonstrate higher levels of attentional interference for aggression words, but only in the presence of alcohol cues. Conversely, individuals higher on angry temperament evidenced higher levels of attentional interference, but only in the absence of alcohol cues. It appears that the relationships among these variables are by no means straightforward. Studies that include an opportunity to aggress behaviorally may shed more light on whether ones level of attentional interference and self-reported personality traits can be combined to predict aggression in the presence of alcohol cues. The parafoveal visual task is recommended as the methodology of choice for these future studies.

Bronfenbrenners Process-Person-Context-Time model was used to examine the relationships among the process of negative parenting, the person characteristics of child temperament and early aggressive behaviour and the contexts of family income (in)adequacy and maternal depression from infancy to school entry and their effects on the outcome of aggressive behaviour in boys at school entry. The sample included 361 boys in two-parent families who participated in the Canadian National Longitudinal Survey of Children and Youth (NLSCY). Structural equation modeling was used with a repeated measures longitudinal design. The model explained 43% of the variance in boys aggressive behaviour at school age. The results indicated that, by preschool age, boys and mothers behaviours are well established, and that process, person, and context variables all influence the persistence of boys aggressive behaviour. The strength of the effects of these variables increased with their proximity to the developing child and decreased over time. By school age, concurrent effects were not significant. The addition of the contextual variables resulted in ill-fitting models. Modification indices suggested the ill fit was localized in modeling the persistence of maternal depression, and not in the relationship between maternal depression and the other variables in the model. Modification indices also suggested there may be reciprocal effects between boys aggressive behaviour and both negative parenting and maternal depression, but this was not tested. Future research using a cross-lagged panel design could clarify these relationships. This study contributes to a growing body of research on the development of aggressive behaviour in children and underscores the importance of examining the contribution of the multiple levels of process, person, context, and time to the development of aggressive behaviour. Findings of this study provide evidence that the effects of proximal processes and proximal contexts on the development of boys aggressive behaviour are strongest in infancy and toddlerhood, and their consequences extend through to school entry. Initiating prevention and intervention efforts in early childhood that provide parents-to-be and parents of young children with practical direction in ways to engage in positive and responsive interactions with their children would do more to reduce the development of aggressive behaviour in children than would later interventions aimed at changing entrenched behaviours in both parents and children.

Variation in animal personality, in other words, behavioural responses consistent within individuals over time and/or across contexts, is predicted to be related to life-history traits, such as growth rate and investment in reproduction. How this translates into relationships between personality and milk production in dairy cows is however scarcely investigated and previous studies are showing contradicting results. To further investigate this relationship, individual consistencies in behaviour were related to milk production in two breeds of dairy cows (Swedish red and white cattle, SRB, and Holstein). Variation was found among the breeds in consistency of behaviours and both SRB and Holstein cows were highly consistent over time in stepping behaviour during milking and frequency of performed abnormal behaviours in home pen. Overall were Holstein cows consistent in more observed behaviours than SRB. Variation in neophobia and responses to social separation were more flexible, both among breeds and over time. Nevertheless, behaviour showed limited relationship with milk production. To conclude, the tests here carried out are useful in describing personality in cows; however, personality showed no relationship with milk production, encouraging future studies to explore this expected relationship further in other breeds and species.

Objectives were to characterize residual feed intake (RFI) and determine the phenotypic correlation between performance, feed efficiency, and other biological measurements in Brahman heifers, as well as the relationship between RFI determined in confinement and measurements of grazing activity on pasture. Three separate 70 d feeding trials were performed, and RFI was determined as the residual between actual and predicted dry matter intake (DMI) for a given level of production. Brahman heifers (n = 103; 5-to-9 mo of age) were individually limit-fed a pelleted 12% CP complete ration daily in Calan gates. Weekly body weight (BW) and DMI data were collected, and predicted DMI was determined by linear regression of actual DMI on mid-test metabolic BW. Ytterbium chloride was used to evaluate digestive kinetics, and fecal samples were collected to determine fecal volatile fatty acids (VFA) concentration and determine apparent dry matter digestibility (DMD) utilizing acid insoluble ash as an internal marker. Measurements of temperament were evaluated on all heifers at weaning. High (n = 6) and low (n = 6) RFI heifers (Exp. I) grazed fescue and ryegrass to determine variation in grazing behavior, DMI, and apparent DMD. Data from all three experiments were pooled, and RFI was not correlated with average daily gain (ADG), DMI, BW, partial efficiency of gain, feed conversion ration, fecal VFA concentration, or any measures of temperament. There were no significant differences in digestive kinetics between the RFI efficiency groups. Fecal samples taken for acid detergent insoluble ash (ADIA) determination were not collected at frequent enough intervals to account for weekly variation in fecal ADIA concentration. Pasture measurements were not different between the efficiency groups for heifers evaluated for grazing behavior, as well as estimated intake as a proportion of BW, or apparent DMD. Results of this study suggest that Bos indicus cattle appear to have similar efficiency traits as Bos taurus and Bos indicus influenced cattle, making this measure of efficiency equally as valid for use in both types of cattle. This indicates that selection based on RFI can be made to increase feed efficiency without affecting ADG or BW in Brahman cattle.

The aim of this study is to investigate differences in peer preference, gender and temperamental characteristics of 5 and 6 year old children on their social competence and behavioral problems. More specifically, the present study examined whether being boy or girl, being more preferred peer or less preferred and different temperamental characteristics differentiates children&rsquo / s social competence, anger- aggression and anxiety withdrawal related behaviors. Peer preference was determined by the &ldquo / Picture Sociometry Scale&rdquo / which was an implementation conducted with children. Teachers were asked to fill the &ldquo / Social Competence and Behavior Evaluation Scale&rdquo / for each child participated in the study in their classrooms. Moreover, parents of children participated in the study were requested to complete &ldquo / Short Temperament Scale for Children&rdquo / . The participants of this study consisted of 42 5- 6 year old children from one private pre- school in Ankara. Results of this study revealed that, children with higher peer preference showed more social competence. Moreover, children with higher persistence and approach as temperamental characteristics revealed higher social competence while children with higher reactivity as a temperamental characteristic had also higher anger- aggression behavioral problems. However, gender of children did not differentiate children&rsquo / s social competence, anger- aggression and anxiety withdrawal related behaviors.

Measures of temperament including exit velocity (EV) and pen score (PEN) and were compared over 3 repeated observations (60-d interval) of yearling Brahman bulls (initial BW = 320 ± 4 kg; n = 66). Exit velocity measures were correlated; EV1 to EV2 (r = 0.32, P = 0.01), EV1 to EV3 (r = 0.31, P = 0.02), and EV2 to EV3 (r = 0.47, P < 0.001). Both EV and PEN were correlated with serum cortisol (CS) within Time 1 and Time 3; EV1 to CS1 (r = .26, P = 0.04), PEN1 to CS1 (r = 0.29, P = 0.02), and EV3 to CS3 (r = 0.44, P < 0.001). Two-year old Brahman heifer were given an ACTH challenge. The calm (C) and temperamental (T) groups consisted of 6 slow (EV=1.05 ± 0.05 m/sec) and 6 fast (EV = 3.14 ± 0.22 m/sec) heifers. Prior to ACTH challenge, T heifers had elevated CS (T = 48.97 ± 3.42, C = 29.60 ± 5.46 ng/mL). Basal CS was higher (P < 0.001) in T heifers (18.20 ± 2.63, C = 4.30 ± 0.58 ng/mL). Following ACTH (0.1 IU ACTH per kg BW) area under the response curve (AUC) was greater (P = 0.07) in C heifers (T = 69.08 ± 10.69, C = 95.87 ± 7.24 ng·h/mL). After declining below basal concentrations, CS in T heifers were again greater (P = 0.02) than in C heifers. The same heifers were subjected to a CRH challenge (0.1 µg bCRH per kg BW). Prior to CRH area under the ACTH curve was greater (P = 0.025) in T heifers (T = 385.72 ± 49.97, C = 239.24 ± 24.04 pg·h/mL). Basal ACTH did not differ (P = 0.10) between temperament groups. Area under the ACTH response curve was greater (P = 0.057) in C heifers (C = 66.72 ± 10.65, T = 38.11 ± 6.44 pg·h/mL). These data demonstrate that cattle with poor temperament exhibit increased stress responsiveness to handling, increased baseline adrenal function but not increased basal pituitary function, and a muted responsiveness to pharmacological stimulus. Thus functional characteristics of the HPA axis vary with animal temperament.
