Small to medium-sized enterprises (SMEs) in Hobart, Tasmania, Australia face many barriers to recycling participation. This study first investigated the volumes and types of waste produced by SMEs. Significant barriers were then identified and key motivators to recycle examined. Using the Australia New Zealand Standard of Industrial Classification, stratified sampling of SMEs (n = 436) was unde...

In the present work, some efforts have been made to search of effective rotation patterns in estimation of precision of population mean of study variable on current occasion in two-occasion successive sampling. Information on an auxiliary character, which is readily available on previous and current occasion, has been used along with the information on study character from the first and second ...

Ramirez BU. The sensory modality used for learning affects grades. Adv Physiol Educ 35: 270–274, 2011; doi:10.1152/advan.00010.2011.—Second-year undergraduated students from 2008, 2009, and 2010 cohorts were asked to respond a questionnaire to determine their learning style preferences, the VARK questionnaire (where V is visual, A is aural, R is reading-writing, and K is kinesthetic), which was...

We study the statistical properties of the least squares estimator in unimodal sequence estimation. Although closely related to isotonic regression, unimodal regression has not been as extensively studied. We show that the unimodal least squares estimator is adaptive in the sense that the risk scales as a function of the number of values in the true underlying sequence. Such adaptivity properti...

It is well established that a formal language generated from a unimodal map is regular if and only if the map’s kneading sequence is either periodic or eventually periodic. A previously proposed conjecture said that if a language generated from a unimodal map is context-free, then it must be regular, i.e. there exists no proper context-free language which can be generated from a unimodal map. T...

The detection and localization of a target from samples of its generated field is a problem of interest in a broadrange of applications. Often, the target field admits structural properties that enable the design of lower sampledetection strategies with good performance. This paper designs a sampling and localization strategy which exploitsseparability and unimodality in target fiel...

In performing a Bayesian analysis of astronomical data, two difficult problems often emerge. First, in estimating the parameters of some model for the data, the resulting posterior distribution may be multimodal or exhibit pronounced (curving) degeneracies, which can cause problems for traditional Markov Chain Monte Carlo (MCMC) sampling methods. Second, in selecting between a set of competing ...

A polynomial is unimodal if its sequence of coefficients are increasing up to an index, and then are decreasing after that index. A polynomial is logconcave if the sequence of the logarithms of the coefficients is concave. We prove that if P (x) is a polynomial with nonnegative non-decreasing coefficients then P (x+z) is unimodal for any natural z. Furthermore, we prove that if P (x) is a log-c...

Niche theory predicts that species occurrence and abundance show non-linear, unimodal relationships with respect to environmental gradients. Unimodal models, such as the Gaussian (logistic) model, are however more difficult to fit to data than linear ones, particularly in a multi-species context in ordination, with trait modulated response and when species phylogeny and species traits must be t...

While the Matrix Generalized Inverse Gaussian (MGIG) distribution arises naturally in some settings as a distribution over symmetric positive semi-definite matrices, certain key properties of the distribution and effective ways of sampling from the distribution have not been carefully studied. In this paper, we show that the MGIG is unimodal, and the mode can be obtained by solving an Algebraic...
