Executive Systems Constrain the Flexibility of Online Control in Children During Goal-Directed Reaching

We examined the influence of inhibitory load on online motor control in children. A sample of 129 school children was tested: younger, mid-age, and older children. Online control was assessed using a double-step perturbation paradigm across three trail types: non-jump, jump, and anti-jump. Results show that mid-aged children were able to implement online adjustments to jump trials as quickly as older children, but their performance on anti-jump trials regressed toward younger children. This suggests that rapid unfolding of executive systems during middle childhood may constrain the flexibility with which online control can be implemented, particularly when inhibitory demands are imposed.

Phase and crystal orientation study of a TRansformation Induced Plasticity steel subjected to cyclic load induced fatigue

An electron backscatter diffraction (EBSD) study of the microstructure of TRIP steel during fatigue failure. Phase and crystal orientation study of a TRIP steel subjected to cyclic load induced fatigue. The relative fractions of austenite, ferrite and martensite are quantified within the strain field of a fatigue crack tip. This data is a subset of data supporting a wider study of the fatigue properties of multiphase steels used in the automotive industry. The different microstructural phases present in these steels can influence the strain life and cyclic stabilized strength of the material due to the way in which these phases accommodate the applied cyclic strain. Fully reversed strain-controlled low-cycle fatigue tests have been used to determine the mechanical fatigue performance of a dual-phase (DP) 590 and transformation induced plasticity (TRIP) 780 steel, with transmission electron microscopy (TEM) and scanning electron microscopy (SEM-EBSD) used to examine the deformed microstructures .

Space vector modulation based fast speed response field-orientation control of induction motor drive with adaptive neural integrator

This paper presents a novel fast speed response control strategy for the poly-phase induction motor drive system based on flux angle. The control scheme is derived in rotor field coordinates and employs the estimation of the rotor flux and its position. An adaptive notch filter is proposed to eliminate the dc component of the integration of signals used for the rotor flux estimation. To improve the performance of the rotor flux estimator, derivative term of the back emf is incorporated in the system. The voltage components in the synchronous reference frame are generated in the controllers which are transformed to stationary reference frame for driving the motor. Space vector modulation technique is used here. Simulation of the drive system was carried out and the results were compared with those obtained for a system that produces the above mentioned voltage components using the conventional PI controller. It is observed that the proposed control methodology provides faster response than the conventional PI controller incorporated system.

New rules, no rules, old rules or our rules : women designing mixed-orientation relationships with bisexual men

This chapter draws from an Australian semi-structured interview project with seventy-eight culturally, sexually and geographically diverse women, aged nineteen to sixty-five, who were in monogamous, open and polyamorous marital and de facto relationships with bisexual men, abbreviated as MOREs (mixed-orientation relationships).
For the purposes of this chapter, I will provide an overview of the shifting subjectivities, agency and resistance of those women and their male partners who stated that, without coercion or repression, they undertook processes of ‘designing’ their long-term MOREs.
I wiIl explore what every woman stated as being an essential component of consensually and creatively entering or being in a relationship with a bisexual man: designing, negotiating and maintaining some “ground rules” and “boundaries”.
There appear to be three overall groups of ‘rules’ within which specific ‘designs’ are created:
1. ‘Old Rules’: Monogamy is considered the only workable or desirable rule, and a partner’s inability to adhere to monogamy would mean the end of the relationship.
2. ‘New Rules’: A range of negotiations and design-specifications establish non-monogamous boundaries and operational strategies.
3. ‘Our Rules or His and Her Rules’: Decisions are made regarding to what extent the rules will be equitable to both, or there are separate regulations for each partner.

Brand orientation and service quality in online and offline environments: empirical examination in higher education

This study examines the relationship between perceived brand orientation (PBO) and service quality (SERVQUAL) in both online and offline education environment. A total of 476 questionnaires were completed by undergraduate students of a particular university in Australia. Structural equation modeling was employed in this study to examine the associations between PBO and service quality (SERVQUAL). The “interaction” dimension of PBO is significantly related to all elements of SERVQUAL in both groups. The “affect” dimension is only significantly related to the “tangibles” dimension in the online groups and is not significantly related to all SERVQUAL dimension in the offline groups

Adolescent peer group orientation, parent/attachment styles and mental health

Jennette Robinson’s research examined peer group characteristics and their relationship to parent/peer attachment, parenting styles, and adolescent functioning. Secure parental attachments were not associated with easier group access or participation in a greater number of groups. Evidence supported a relationship between parenting style and both group establishment and membership hierarchy.

Coupling online control and inhibitory systems in children with developmental coordination disorder: goal-directed reaching

For children with Developmental Coordination Disorder (DCD), the real-time coupling between frontal executive function and online motor control has not been explored despite reported deficits in each domain. The aim of the present study was to investigate how children with DCD enlist online control under task constraints that compel the need for inhibitory control. A total of 129 school children were sampled from mainstream primary schools. Forty-two children who met research criteria for DCD were compared with 87 typically developing controls on a modified double-jump reaching task. Children within each skill group were divided into three age bands: younger (6-7 years), mid-aged (8-9), and older (10-12). Online control was compared between groups as a function of trial type (non-jump, jump, anti-jump). Overall, results showed that while movement times were similar between skill groups under simple task constraints (non-jump), on perturbation (or jump) trials the DCD group were significantly slower than controls and corrected trajectories later. Critically, the DCD group was further disadvantaged by anti-jump trials where inhibitory control was required; however, this effect reduced with age. While coupling online control and executive systems is not well developed in younger and mid-aged children, there is evidence of age-appropriate coupling in older children. Longitudinal data are needed to clarify this intriguing finding. The theoretical and applied implications of these results are discussed.

Senior marketers’ insights into the challenges of social media implementation in large organisations: assessing generic and electronic orientation models as potential solutions

The unique characteristics of social media (SM) have made it difficult to implement this tool within many large organisations. This paper seeks to identify the implementation challenges and evaluate alternative organisational orientations that may provide solutions. We aimed to reconcile theory with current practice by integrating the extant literature with data from three focus groups involving 27 senior marketing executives. The managerial discussions identified additional challenges to those previously discussed in the literature, which appear to result from SM’s unique characteristics. These include: interactivity, the integration of communication into distribution channels, collaborative media and information collection. Using both broad orientation models (market orientation and entrepreneurial orientation) and a specific digital orientation (e-marketing orientation), guidelines and research propositions for effective implementation are put forward.
