    The Goldilocks Effect of Strategic Human Resource Management? Optimizing the Benefits of a High-Performance Work System Through the Dual Alignment of Vertical and Horizontal Fit

    Although vertical and horizontal fit in strategic human resource management are foundational to the links between a high-performance work system (HPWS) and organizational performance, little is known about how these two fits interact to affect organizational performance. We address this shortcoming while also advancing knowledge on each type of fit. We offer a more nuanced examination of vertical fit (which has typically been assessed with respect to organizations\u27 broad strategic types) by focusing on the alignment of an HPWS with an organization\u27s market entry timing mode—a key element of strategy. We propose that among organizations pursuing new product development, the effect of an HPWS on organizational performance is most positive under a fast-follower entry timing, followed by a first-mover and finally a fence-sitter entry timing. We then hypothesize that the benefit of vertical fit is magnified when the complementary human resources practices comprising an HPWS are implemented with greater internal consistency (or with similar intensities) across the ability, motivation, and opportunity domains—reflecting a positive interaction between vertical and horizontal fit in predicting the effectiveness of an HPWS. Analyses of four-wave nationally representative panel data yield strong support for our dual-alignment model of SHRM

    Purpose – Most of the studies in entrepreneurship depend on single-source rating methods to collect data on both predictors and criteria. The threat to effect sizes as a result of using single-source ratings is particularly relevant to psychology-based entrepreneurship research. Therefore, the purpose of the present paper is to explore the prospects of applying 360 degree feedback to the field of entrepreneurship and to discuss a set of cases regarding how 360 degree feedback may boost effect sizes in entrepreneurship research. Design/methodology/approach – A qualitative review of current literature was performed. Findings – The review indicated that (1) the effect sizes in psychology-based entrepreneurship research are mostly small and the use of single-source ratings is prevalent; (2) some preliminary findings supported the utility of 360 degree feedback in entrepreneurship research; (3) entrepreneurial orientation (EO) research may benefit from 360 degree feedback; and (4) members of top management teams, employees from research and product development, sales agents, retail buying agents, store sales clerks, and consumers are all good informants to provide ratings of EO. Originality/value – The present study provided theoretical explanations and used empirical evidence to elucidate how 360 degree feedback may benefit the field of entrepreneurship. In addition, recommendations for future research using 360 degree feedback in entrepreneurship research were offered and discussed. A sample research study on EO using 360 degree feedback was delineated

    Ubiquitin ligase MKRN1 modulates telomere length homeostasis through a proteolysis of hTERT

    Telomere homeostasis is regulated by telomerase and a collection of associatedproteins. Telomerase is, in turn, regulated by post-translational modifications of the rate-limiting catalytic subunit hTERT. Here we show that disruption of Hsp90 by geldanamycin promotes efficient ubiquitination and proteasome-mediated degradation of hTERT. Furthermore, we have used the yeast two-hybrid method to identify a novel RING finger gene (MKRN1) encoding an E3 ligase that mediates ubiquitination of hTERT. Overexpression of MKRN1 in telomerase-positive cells promotes the degradation of hTERT and decreases telomerase activity and subsequently telomere length. Our data suggest that MKRN1 plays an important role in modulating telomere length homeostasis through a dynamic balance involving hTERT protein stability

    Large expert-curated database for benchmarking document similarity detection in biomedical literature search

    Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe

    The same neuron may play different functional roles in the neural circuits to which it belongs. For example, neurons in the Tritonia pedal ganglia may participate in variable phases of the swim motor rhythms [1]. While such neuronal functional variability is likely to play a major role the delivery of the functionality of neural systems, it is difficult to study it in most nervous systems. We work on the pyloric rhythm network of the crustacean stomatogastric ganglion (STG) [2]. Typically network models of the STG treat neurons of the same functional type as a single model neuron (e.g. PD neurons), assuming the same conductance parameters for these neurons and implying their synchronous firing [3, 4]. However, simultaneous recording of PD neurons shows differences between the timings of spikes of these neurons. This may indicate functional variability of these neurons. Here we modelled separately the two PD neurons of the STG in a multi-neuron model of the pyloric network. Our neuron models comply with known correlations between conductance parameters of ionic currents. Our results reproduce the experimental finding of increasing spike time distance between spikes originating from the two model PD neurons during their synchronised burst phase. The PD neuron with the larger calcium conductance generates its spikes before the other PD neuron. Larger potassium conductance values in the follower neuron imply longer delays between spikes, see Fig. 17.Neuromodulators change the conductance parameters of neurons and maintain the ratios of these parameters [5]. Our results show that such changes may shift the individual contribution of two PD neurons to the PD-phase of the pyloric rhythm altering their functionality within this rhythm. Our work paves the way towards an accessible experimental and computational framework for the analysis of the mechanisms and impact of functional variability of neurons within the neural circuits to which they belong
