Absorptive Capacity: Empirical Exploration on Trait of Organizational Structure and Absorptive Capacity Practices
Technology Management/ Information System/ EntrepreneurshipOpen innovation literature argues that firms need to identify new knowledge and collaborate it through the innovation process. In line with the issue, absorptive capacity has been highlighted in the various fields such as technology management, strategic management, international business and organizational economics. But the component, outcomes, antecedents and definition of absorptive capacity is diverse and somewhat ambiguous. Relevant to this issue, many studies attempted to conceptualize absorptive capacity with different definitions and dimensions. However, few undertake dealing with other antecedents such as characteristics of organizational structure. In this paper, we aim to empirically explore the antecedents of absorptive capacity, namely formalization, decentralization, and coordination capability, those which possibly affect the potential absorptive capacity and realized absorptive capacity. Further, we try to find effect of absorptive capacity practices on absorptive capacity. By doing so, findings are expected to allow firms to better understand how absorptive capacities can be developed.ope

Mikrokosmos and 32 Piano Games: Introducing Contemporary Musical Language and Developing Piano Technique for the Beginning Student
As new musical styles have emerged in the twentieth century with characteristic sounds, chords, forms, meters, and intervals, teachers need to broaden and re-define the way they introduce musical concepts to beginning piano students. The purpose of this study is to offer different instructional possibilities aside from conventional methods of teaching beginning pianists. This is accomplished through a comparison of the two different approaches of the Hungarian composer BĂ©la BartĂłk and the American composer Ross Lee Finney. BartĂłkâs Mikrokosmos, a graded set of 153 pieces, and Finney's 32 Piano Games are examined through this paper
Goal-directed action is automatically biased towards looming motion
AbstractIt is known that looming motion can capture attention regardless of an observerâs intentions. Real-world behavior, however, frequently involves not just attentional selection, but selection for action. Thus, it is important to understand the impact of looming motion on goal-directed action to gain a broader perspective on how stimulus properties bias human behavior. We presented participants with a visually-guided reaching task in which they pointed to a target letter presented among non-target distractors. On some trials, one of the pre-masks at the location of the upcoming search objects grew rapidly in size, creating the appearance of a âloomingâ target or distractor. Even though looming motion did not predict the target location, the time required to reach to the target was shorter when the target loomed compared to when a distractor loomed. Furthermore, reach movement trajectories were pulled towards the location of a looming distractor when one was present, a pull that was greater still when the looming motion was on a collision path with the participant. We also contrast reaching data with data from a similarly designed visual search task requiring keypress responses. This comparison underscores the sensitivity of visually-guided reaching data, as some experimental manipulations, such as looming motion path, affected reach trajectories but not keypress measures. Together, the results demonstrate that looming motion biases visually-guided action regardless of an observerâs current behavioral goals, affecting not only the time required to reach to targets but also the path of the observerâs hand movement itself
Dissociable Effects of Salience on Attention and Goal-Directed Action
SummaryEveryday behavior frequently involves encounters with multiple objects that compete for selection. For example, driving a car requires constant shifts of attention between oncoming traffic, rearview mirrors, and traffic signs and signals, among other objects. Behavioral goals often drive this selection process [1, 2]; however, they are not the sole determinant of selection. Physically salient objects, such as flashing, brightly colored hazard signs, or objects that are salient by virtue of learned associations with reward, such as pictures of food on a billboard, often capture attention regardless of the individualâs goals [3â6]. It is typically thought that strongly salient distractor objects capture more attention and are more disruptive than weakly salient distractors [7, 8]. Counterintuitively, though, we found that this is true for perception, but not for goal-directed action. In a visually guided reaching task [9â11], we required participants to reach to a shape-defined target while trying to ignore salient distractors. We observed that strongly salient distractors produced less disruption in goal-directed action than weakly salient distractors. Thus, a strongly salient distractor triggers suppression during goal-directed action, resulting in enhanced efficiency and accuracy of target selection relative to when weakly salient distractors are present. In contrast, in a task requiring no goal-directed action, we found greater attentional interference from strongly salient distractors. Thus, while highly salient stimuli interfere strongly with perceptual processing, increased physical salience or associated value attenuates action-related interference
Attention modulates generalization of visuomotor adaptation
Generalization represents the ability to transfer what has been learned in one context to another context beyond limited experience. Because acquired motor representations often have to be reinstated in a different or novel environment, generalization is a crucial part of visuomotor learning. In daily life, training for new motor skills often occurs in a complex environment, in which dividing attentional resources for multiple stimuli is required. However, it is unknown how dividing attention during learning affects the generalization of visuomotor learning. We examined how divided attention during training modulates the generalization of visuomotor rotational adaptation. Participants were trained to adapt to one direction with or without dividing attention to a simultaneously presented visual detection task. Then, they had to generalize rotational adaptation to other untrained directions. We show that visuomotor training with divided attention multiplicatively reduces the gain and sharpens the tuning of the generalization function. We suggest that limiting attention narrowly restricts an internal model, reducing the range and magnitude of transfer. This result suggests that attention modulates a selective subpopulation of neurons in motor areas, those with directional tuning values in or near the training direction

Biased Attention Near iCub's Hand After Collaborative HRI
Earlier research has indicated that humans prioritize attention to the space close to their hands, commonly known as the "near-hand effect". This phenomenon also extends to a human partner's hand, but specifically following a shared physical joint action. Consequently, within human dyads, collaborative interaction results in a shared body representation that might impact fundamental attentional mechanisms. Our project investigates whether a similar effect can emerge from a human-robot interaction scenario. In previous work, we have shown that the mere presence of an anthropomorphic robot's hand is not enough to trigger the near-hand effect. Here, we designed an experiment to assess whether a collaborative human-robot interaction with the humanoid robot iCub could bias human attention toward the robot's hand. After the interaction, we replicated a classical psychological paradigm by adding a robotic condition to measure this attentional bias (i.e., the near-hand effect). Our findings indicate the existence of a near-hand effect triggered by the robot's hand, suggesting that HRI can replicate a shared body representation similar to that observed in human dyads, which may influence our basic attentional mechanisms
Increasing the Durability of Piezoelectric Impact-based Micro Wind Generator in Real Application
AbstractThe purpose of this study is to increase the durability of piezoelectric impact-based micro wind generator (PIMWG) in real application. Using new PIMWG design, numerical simulation, and experimental comparison analysis, we improved the durability of PIMWGs in real application. The experimental results show that the optimized PIMWG generated 2.4 mW (RMS value), and it did not crack within 40h. In this study, we improved the durability of PIMWGs for real application
