Abstract Nuclear architecture is fundamental to the manner by which molecules traverse the nucleus. The nucleoplasm is a crowded environment where dynamic rearrangements in local chromatin compaction locally redefine the space accessible toward nuclear protein diffusion. Here, we review a suite of methods based on fluorescence fluctuation spectroscopy (FFS) and how they have been employed to interrogate chromatin organization, as well as the impact this structural framework has on nuclear protein target search. From first focusing on a set of studies that apply FFS to an inert fluorescent tracer diffusing inside the nucleus of a living cell, we demonstrate the capacity of this technology to measure the accessibility of the nucleoplasm. Then with a baseline understanding of the exploration volume available to nuclear proteins during target search, we review direct applications of FFS to fluorescently labeled transcription factors (TFs). FFS can detect changes in TF mobility due to DNA binding, as well as the formation of TF complexes via changes in brightness due to oligomerization. Collectively, we find that FFS-based methods can uncover how nuclear proteins in general navigate the nuclear landscape.

The Impact

Visual search is an important component of many real world tasks such as industrial inspection and driving. Several studies have shown that age has an impact on visual search performance. In general older people demonstrate poorer performance on such tasks as compared to younger people. However, there is controversy regarding the source of the age-performance effect. The objective of this study was to examine the relationship between component abilities and visual search performance, in order to identify the locus of age-related performance differences. Six abilities including reaction time, working memory, selective attention and spatial localization were identified as important components of visual search performance. Thirty-two subjects ranging in age from 18 - 84 years, categorized in three different age groups (young, middle, and older) participated in the study. Their component abilities were measured and they performed a visual search task. The visual search task varied in complexity in terms of type of targets detected. Significant relationships were found between some of the component skills and search performance. Significant age effects were also observed. A model was developed using hierarchical multiple linear regression to explain the variance in search performance. Results indicated that reaction time, selective attention, and age were important predictors of search performance with reaction time and selective attention accounting for most of the variance.

The employees’ need of appreciation emerges in the form of rewards, empowerment and training, the supply of which fuels up performance of employees gaining indirectly by the organization through the interactive organizational practices grooming their skills which is tested and hypothesized many times. This study contributes by taking into account the inclusion of Creative Performance along with the other tested performance levels and also tests the mediating role of Work Engagement in the established relationships. This study helps in establishing this unique relationship observing the role of mediation also. The effects are analyzed with SPSS (21) and AMOS with Structural Equation modeling. Data is gathered from frontline employees of 06 cities of the Bahawalpur Division in Pakistan. The results show that rewards, empowerment and training foster Work Engagement that in turn elevates levels of Performance of Hotel Industry employees. The findings of this study will rebound to the benefit of the organizations regarding the success factors of their employees at workplace as they can get novelty of service ideas through employees. Its implementation will ultimately result in HR techniques to be adopted to achieve higher levels of performance in future. There are many other High-Performance tools like, Realistic Job Previews, Innovation Programs and Performance based Pay. Future studies can be conducted to assess the impact of these factors also. In addition, some psychological constructs may be included to enhance its area of application and know underlying reasons of divert behaviors.

Amid the rapid growth of information today is the increasing challenge for people to navigate its magnitude. Dynamics and heterogeneity of large information spaces such as the Web raise important questions about information retrieval in these environments. Collection of all information in advance and centralization of IR operations are extremely difficult, if not impossible, because systems are dynamic and information is distributed. The chapter discusses some of the key issues facing classic information retrieval models and presents a decentralized, organic view of information systems pertaining to search in large scale networks. It focuses on the impact of network structure on search performance and discusses a phenomenon we refer to as the Clustering Paradox, in which the topology of interconnected systems imposes a scalability limit.

The Impact

Recently, Wang, Buetti and Lleras (2017) developed an equation to predict search performance in heterogeneous visual search scenes (i.e., multiple types of non-target objects simultaneously present) based on parameters observed when participants perform search in homogeneous scenes (i.e., when all non-target objects are identical to one another). The equation was based on a computational model where every item in the display is processed with unlimited capacity and independently of one another, with the goal of determining whether the item is likely to be a target or not. The model was tested in two experiments using real-world objects. Here, we extend those findings by testing the predictive power of the equation to simpler objects. Further, we compare the model’s performance under two stimulus arrangements: spatially-intermixed (items randomly placed around the scene) and spatially-segregated displays (identical items presented near each other). This comparison allowed us to isolate and quantify the facilitatory effect of processing displays that contain identical items (homogeneity facilitation), a factor that improves performance in visual search above-and-beyond target-distractor dissimilarity. The results suggest that homogeneity facilitation effects in search arise from local item-to-item interaction (rather than by rejecting items as “groups”) and that the strength of those interactions might be determined by stimulus complexity (with simpler stimuli producing stronger interactions and thus, stronger homogeneity facilitation effects).

ABSTRACT I empirically investigate the impact of an organization's creativity dependency on the design of its incentive system. In firms for which the primary source of value creation is the creativity of core employees, the designs of incentive systems are particularly challenging. The nature of creative work constrains the feasibility of extrinsic incentives, but at the same time creates a need for them. Accordingly, there is concern that the use of incentives renders people not creative enough, but a lack of incentives makes employees “too creative.” I argue that a solution to this dilemma is the acknowledgment that the decision to use performance-based pay is not made in isolation, but as part of a set of complementary choices. I theoretically argue and empirically show that subjective evaluations of non-task-related performance and performance-based pay are complements in a creativity-dependent setting. I further argue that the intense use of both control mechanisms is the incentive system that best accommodates the control requirements of creativity-dependent firms, and show that the likelihood of choosing this system increases with the creativity dependency.
