Estimation of instrinsic dimension via clustering

The problem of estimating the intrinsic dimension of a set of points in high dimensional space is a critical issue for a wide range of disciplines, including genomics, finance, and networking. Current estimation techniques are dependent on either the ambient or intrinsic dimension in terms of computational complexity, which may cause these methods to become intractable for large data sets. In this paper, we present a clustering-based methodology that exploits the inherent self-similarity of data to efficiently estimate the intrinsic dimension of a set of points. When the data satisfies a specified general clustering condition, we prove that the estimated dimension approaches the true Hausdorff dimension. Experiments show that the clustering-based approach allows for more efficient and accurate intrinsic dimension estimation compared with all prior techniques, even when the data does not conform to obvious self-similarity structure. Finally, we present empirical results which show the clustering-based estimation allows for a natural partitioning of the data points that lie on separate manifolds of varying intrinsic dimension

Okun’s law, asymmetries and jobless recoveries in the United States: A Markov-switching approach

This paper offers a new perspective on Markov regime-switching approaches to asymmetries in Okun’s law by modeling the existing approaches as special cases. Prevailing models assume either asymmetry between unemployment and output across regimes or asymmetry within a single regime. Our specification combines both approaches. Our empirical results give an insight into the apparent ‘jobless recovery’ experiences that began in the United States in 1991 and 2001

Business confidence and cyclical turning points: A Markov-Switching approach

Markov regime-switching analysis is used to consider the relationship between business confidence and the probability of turning points in cyclical GDP. We find, in an application to New Zealand, that confidence is related to both the deepness and duration of the business cycle and is asymmetric regarding the probability of the economy remaining in a given regime. Overall, the New Zealand business confidence series is a useful indicator of cyclical turning points

A closer look at Cleveland's latest poverty ranking

News that Cleveland’s poverty rate is the worst in the nation--and rising--has elevated the community’s concern about conditions in the city. But a closer look at the way poverty rates are calculated suggests that all the possible causes of Cleveland’s ranking have not been fully understood.Poverty - Cleveland (Ohio) ; Economic conditions - Cleveland (Ohio)

Designing a design thinking approach to HRD

This article considers the value of design thinking as applied to a HRD context, Specifically, it demonstrates how design thinking can be employed through a case study drawn from the GETM3 programme. It reports on the design, development, and delivery of a design thinking workshop which was created to draw out and develop ideas from students and recent graduates about the fundamental training and skills requirements of future employment. While design thinking has been widely deployed in innovation and entrepreneurship, its application to HRD is still very much embryonic. Our overview illustrates how the key characteristics of the design thinking process resonate with those required from HRD (e.g. focus on end user, problem solving, feedback, and innovation). Our contribution stems from illuminating a replicable application of design system thinking including both the process and the outcomes of this application. We conclude that design thinking is likely to serve as a critical mind-set, tool, and strategy to facilitate HRD practitioners and advance HRD practice
