Communication satisfaction, job satisfaction, organisational commitment and intention to leave
The retention of highly motivated, skilled and committed employees is a major concern by organisations to achieve a competitive advantage. The turnover intentions of human capital are of interest to managers, employees, and organisations today. This study explores a theoretical model of turnover intentions that included three proximal variables, job satisfaction, affective and continuance commitment, the distal variables of subordinate communication, horizontal communication, personal feedback, media quality, communication climate, supervisor communication, job-related communication, and management communication, with turnover intentions. A questionnaire was completed by 101 participants of a rental firm in New Zealand. Job satisfaction, affective commitment, continuance commitment, subordinate communication, horizontal communication, personal feedback, media quality, communication climate, supervisor communication, job-related communication, and management communication correlated with turnover intentions. The results of the mediated regression analysis indicated that job satisfaction, affective commitment, and continuance commitment are significant mediators between the eight distal (organisational communication) variables, with turnover intentions.
This study highlights the necessity for managers to develop good quality relationships with their employees to improve the quality of their communication, to foster job satisfaction, affective commitment, and continuance commitment to reduce turnover intentions. The conclusion of this study discusses the practical implications for managers, and organisations and the direction for future research

Quantifying the interplay between environmental and social effects on aggregated-fish dynamics
Demonstrating and quantifying the respective roles of social interactions and
external stimuli governing fish dynamics is key to understanding fish spatial
distribution. If seminal studies have contributed to our understanding of fish
spatial organization in schools, little experimental information is available
on fish in their natural environment, where aggregations often occur in the
presence of spatial heterogeneities. Here, we applied novel modeling approaches
coupled to accurate acoustic tracking for studying the dynamics of a group of
gregarious fish in a heterogeneous environment. To this purpose, we
acoustically tracked with submeter resolution the positions of twelve small
pelagic fish (Selar crumenophthalmus) in the presence of an anchored floating
object, constituting a point of attraction for several fish species. We
constructed a field-based model for aggregated-fish dynamics, deriving
effective interactions for both social and external stimuli from experiments.
We tuned the model parameters that best fit the experimental data and
quantified the importance of social interactions in the aggregation, providing
an explanation for the spatial structure of fish aggregations found around
floating objects. Our results can be generalized to other gregarious species
and contexts as long as it is possible to observe the fine-scale movements of a
subset of individuals.Comment: 10 pages, 5 figures and 4 supplementary figure
Cell Class-Dependent Intracortical Connectivity and Output Dynamics of Layer 6 Projection Neurons of the Rat Primary Visual Cortex
Neocortical information processing is powerfully influenced by the activity of layer 6 projection neurons through control of local intracortical and subcortical circuitry. Morphologically distinct classes of layer 6 projection neuron have been identified in the mammalian visual cortex, which exhibit contrasting receptive field properties, but little information is available on their functional specificity. To address this we combined anatomical tracing techniques with high-resolution patch-clamp recording to identify morphological and functional distinct classes of layer 6 projection neurons in the rat primary visual cortex, which innervated separable subcortical territories. Multisite whole-cell recordings in brain slices revealed that corticoclaustral and corticothalamic layer 6 projection neurons exhibited similar somatically recorded electrophysiological properties. These classes of layer 6 projection neurons were sparsely and reciprocally synaptically interconnected, but could be differentiated by cell-class, but not target-cell-dependent rules of use-dependent depression and facilitation of unitary excitatory synaptic output. Corticoclaustral and corticothalamic layer 6 projection neurons were differentially innervated by columnar excitatory circuitry, with corticoclaustral, but not corticothalamic, neurons powerfully driven by layer 4 pyramidal neurons, and long-range pathways conveyed in neocortical layer 1. Our results therefore reveal projection target-specific, functionally distinct, streams of layer 6 output in the rodent neocortex
