A Time to Act or to Bide Your Time?

A non-inflationary menetary rule and a steady fiscal policy commitment should be adopted forthwith. This would give the Chancellor and the Treasury time to simplify and reform out over-complex and distortionary tax system.     

An investigation into blood donation intentions among non‐donors

• In broad terms, the donation of blood along with organ and bone marrow donation is considered to be the ultimate act of humanity involving a voluntary and anonymous exchange between two people of a life saving commodity. Yet motivating people to donate blood is a significantly difficult task. The aim of this paper is to use the Theory of Planned Behaviour (TPB) to examine non‐donors on the basis of their likely intention to donate blood in the future and to identify barriers on these more favourable non‐donors. This exploratory research finds that subjective norm, perceived behavioural control and time related barriers are related to intent to donate by current non‐donors. Differences between higher and lower intention donors are also explored.

On the financial balance of input–output constructs: revisiting an axiomatic evaluation

Financial balance is fundamental to input–output (IO) analysis, and consequently the respect of this balance is one of the dominant criteria in evaluating IO constructs. Kop Jansen, and ten Raa [(1990) The Choice of Model in the Construction of Input–Output Coefficients Matrices. International Economic Review 31, 213] proved that the byproduct-technology construct (BTC) and the industry-technology construct (ITC) do not generally conserve financial balance. In contrast, Majeau-Bettez et al. [(2016) When do Allocations and Constructs Respect Material, Energy, Financial, and Production Balances in LCA and EEIO? Journal of Industrial Ecology 20, 67–84] demonstrated that the BTC necessarily respects financial balance and that the ITC is always financially balanced when applied to data recorded in monetary units. The present article resolves this paradox.     

Influence of Socio-Demographics and Residential Environment on Leisure Activity Participation

Participating in leisure activities provides important benefits for all people. However, there is a substantial reduction of (green) leisure opportunities in cities, and the green spaces that are available often are poorly accessible. The purpose of this study is to analyze the diversity of participation in various types of leisure activities and to determine the relationship between leisure activity participation and characteristics of the residential environment depending on socio-demographic characteristics. Diary data from 803 respondents living in the Eindhoven region in the Netherlands were used. Four segments were identified that differ regarding their leisure activity participation, and a modest impact of green space accessibility was found.

About the authors

This paper has the implicit theme that there are changes afoot in both the marketing and accounting professions. Explicitly, how changes in the accounting area may affect marketing people is explored. The particular focus is brands, especially their capitalization in the balance sheet of some companies. The controversy around this practice is discussed, and suggestions for the possible impact on marketing outlined. Many companies are already reviewing the way that they manage their brands, and some are. restructuring accordingly. This may be the beginning of many such changes.

The brand valuation and capitalization debate is reviewed from the late 1980s to date. The Accounting Standards Board (ASB) has now released Financial Reporting Standards that relate to the discussion, but do not, as one might hope, conclude it. The standards deal with intangible assets generally, rather than brands specifically. Hence the treatment of brands remains ambiguous and open to interpretation.

Financial reporting systems, which still seem to focus brands as short‐term propositions, are far removed from the way that many marketers and some accountants believe brands should be managed. Therefore, it is concluded to be unlikely that these ASB pronouncements will have created a new order.     

A Unifying Framework and Comparison of Algorithms for Non-negative Matrix Factorisation

Non-negative matrix factorisation (NMF) is an increasingly popular unsupervised learning method. However, parameter estimation in the NMF model is a difficult high-dimensional optimisation problem. We consider algorithms of the alternating least squares type. Solutions to the least squares problem fall in two categories. The first category is iterative algorithms, which include algorithms such as the majorise–minimise (MM) algorithm, coordinate descent, gradient descent and the Févotte-Cemgil expectation–maximisation (FC-EM) algorithm. We introduce a new family of iterative updates based on a generalisation of the FC-EM algorithm. The coordinate descent, gradient descent and FC-EM algorithms are special cases of this new EM family of iterative procedures. Curiously, we show that the MM algorithm is never a member of our general EM algorithm. The second category is based on cone projection. We describe and prove a cone projection algorithm tailored to the non-negative least square problem. We compare the algorithms on a test case and on the problem of identifying mutational signatures in human cancer. We generally find that cone projection is an attractive choice. Furthermore, in the cancer application, we find that a mix-and-match strategy performs better than running each algorithm in isolation.
