AbstractTigersPanthera tigrisare highly threatened and continue to decline across their entire range. Actions to restore and conserve populations need to be based on science but, in South-east Asia, information on ecology and behaviour of tigers is lacking. This study reports the relationship between the home range size of female tigers and prey abundance, using data from radio-collared tigers in Huai Kha Khaeng Wildlife Sanctuary, Thailand, and published data from other studies. A total of 11 tigers, four males and seven females, were fitted with global positioning system collars, to estimate home ranges using 95 and 100% minimum convex polygons (MCP). Prey abundance was estimated by faecal accumulation rates. The mean home range size of male tigers was 267 and 294 km2based on 95 and 100% MCPs, respectively; the mean female home range size was 70 and 84 km2, respectively. Territories of male and female tigers had little overlap, which indicated both sexes were territorial. Mean densities of the prey species sambarRusa unicolor, barking deerMuntiacus muntjacand large bovids were 7.5, 3.5 and 3.0 km−2, respectively. When female home range size and prey abundance were compared at six locations in Thailand, and at other sites in India, Nepal, Bangladesh and Russia, a significant negative correlation was found between prey abundance and home range size. Monitoring this relationship can provide managers with metrics for setting conservation goals.
Tools for thinking applied to nature: an inclusive pedagogical framework for environmental education
Authors: Root-Bernstein Meredith , Root-Bernstein Michele , Root-Bernstein Robert 
Published: March 2014

AbstractAn effective educational framework is necessary to develop the engagement of children and adults with nature. Here we show how the tools for thinking framework can be applied to this end. The tools comprise 13 sensory-based cognitive skills that form the basis for formalized expressions of knowledge and understanding in the sciences and arts. These skills are explicitly taught in some curricula. We review evidence of specific tools for thinking in the self-reported thinking processes and influential childhood experiences of prominent biologists, conservationists and naturalists. Tools such as imaging, abstracting, pattern recognition, dimensional thinking, empathizing, modelling and synthesizing play key roles in practical ecology, biogeography and animal behaviour studies and in environmental education. Ethnographic evidence shows that people engage with nature by using many of the same tools for thinking. These tools can be applied in conservation education programmes at all levels by actively emphasizing the role of the tools in developing understanding, and using them to design effective educational initiatives and assess existing environmental education.
Analytical inverse kinematics for 5-DOF humanoid manipulator under arbitrarily specified unconstrained orientation of end-effector
Authors: Shimizu Masayuki 
Published: March 2014

SUMMARYThis paper proposes an analytical method of solving the inverse kinematic problem for a humanoid manipulator with five degrees-of-freedom (DOF) under the condition that the target orientation of the manipulator's end-effector is not constrained around an axis fixed with respect to the environment. Since the number of the joints is less than six, the inverse kinematic problem cannot be solved for arbitrarily specified position and orientation of the end-effector. To cope with the problem, a generalized unconstrained orientation is introduced in this paper. In addition, this paper conducts the singularity analysis to identify all singular conditions.
Case management and assertive community treatment. What is the difference?
Authors: Burns Tom 
Published: March 2014

AbstractThere has been a long-running controversy about the relative benefits of Assertive Community Treatment (ACT) compared to Case Management (CM). Several health care systems have initiated major service overhauls on the basis of published evidence. Yet this evidence has been ambiguous and supports differing interpretations. Research is examined which explores the differences in outcomes reported. It uses a range of approaches, most prominently meta-regression, to test a small range of hypotheses to explain the heterogeneity in outcomes. The main determinant of differences between ACT and CM studies is the local bed management procedures and occupancy practice. Those organizational aspects of ACT which are generally shared by CM teams are associated with reduced hospital care but the stringent staffing proposed for ACT does not affect it. ACT is a specialized form of CM, not a categorically different approach. The benefits of introducing it will depend on the nature of current local practice. Important lessons about the need to focus on treatments rather than structures seem not to have been learnt. Psychiatry's recent excessive focus on service structures may have had unintended consequences for our professional identity.
Digging deeper into Hardin's pasture: the complex institutional structure of ‘the tragedy of the commons’

Published: March 2014

AbstractA revised application of Ostrom's (Ostrom, 2007) Social-Ecological System (SES) framework to Hardin's ‘tragedy of the commons’ (Hardin, G. (1968), Science, 162(3859): 1243–1248) demonstrates that its institutional structure is more complex than either Hardin or Ostrom had imagined. The ‘tragedy’ arises from several interacting resources and institutions. If the grass on the pasture was not subject to appropriation, the cattle were not privately owned, or property- and contract-enforcement institutions supporting market exchange were absent, then the ‘tragedy of the commons’ would not have arisen regardless of the open-access pasture. This paper highlights the utility of the SES framework and the care required to apply it precisely to specific social-ecological situations.
Testing the Low-density Hypothesis for Reversed Sex Change in Polygynous Fish: Experiments in Labroides dimidiatus
Authors: Kuwamura Tetsuo , Kadota Tatsuru , Suzuki Shohei 
Published: March 2014

AbstractHermaphroditism is ubiquitous among plants and widespread in the animal kingdom. It is an unsolved problem why reversed sex change has evolved in polygynous and protogynous reef fish. We have previously suggested that facultative monogamy occurs in low-density populations of polygynous species and that males that become single as a result of accidental mate loss may change sex when they meet larger males. In this study, to test this ‘low-density hypothesis’, we conducted field experiments with the coral reef fish Labroides dimidiatus in which a portion of females were removed to create a low-density situation. The ‘widowed’ males moved to search for a new mate when no male, female or juvenile fish migrated into their territories and paired with nearby single fish, whether male or female. Alternatively, males expanded their territories to take over the nearest pair whose male was much smaller. These results support our low-density hypothesis.

Background Alcohol use, and particularly unhealthy alcohol use, is associated with poor human immunodeficiency virus (HIV)-related outcomes among persons living with HIV (PLWH). Despite a rapidly growing proportion of PLWH ≥50 years, alcohol use and its associated characteristics are underdescribed in this population. The authors describe alcohol use, severity, and associated characteristics using data from a sample of PLWH ≥50 years who participated in a trial of a telephone-based intervention to improve adherence to antiretroviral therapy (ART). Methods Participants were recruited from acquired immunodeficiency syndrome (AIDS) service organizations in 9 states and included PLWH ≥50 years who were prescribed ART, reported suboptimal adherence at screening (missing >1.5 days of medication or taking medications 2 hours early or late on >3 days in the 30 days prior to screening), and consented to participate. The AUDIT-C (Alcohol Use Disorders Identification Test—Consumption) alcohol screen, sociodemographic characteristics, substance use, and mental health comorbidity were assessed at baseline. AUDIT-C scores were categorized into nondrinking, low-level drinking, and mild-moderate unhealthy, and severe unhealthy drinking (0, 1–3, 4–6, and 7–12, respectively). Analyses described and compared characteristics across drinking status (any/none) and across AUDIT-C categories among drinkers. Results Among 447 participants, 57% reported drinking in the past year (35%, 15%, and 7% reported low-level drinking, mild-moderate unhealthy drinking, and severe unhealthy drinking, respectively). Any drinking was most common among men and those who were lesbian, gay, bisexual, or transgender (LGBT), married/partnered, had received past-year alcohol treatment, and never used injection drugs ( P values all <.05). Differences in race, employment status, past-year alcohol treatment, and positive depression screening ( P values all <.05) were observed across AUDIT-C categories, with African American race, less than full-time employment, past-year alcohol treatment, and positive depression screening being most common among those with the most severe unhealthy drinking. Conclusions In this sample of older PLWH with suboptimal ART adherence, a majority reported past-year alcohol use and 22% screened positive for unhealthy alcohol use. Any and unhealthy alcohol use were associated with demographics, depression, and substance use history. Further research is needed regarding alcohol use among older PLWH.

Abstract
In order to empirically determine the time-scale and environmental dependence of stellar cluster disruption, we have undertaken an analysis of the unprecedented multipointing (seven), multiwavelength (U, B, V, Hα, and I) Hubble Space Telescope imaging survey of the nearby, face-on spiral galaxy M83. The images are used to locate stellar clusters and stellar associations throughout the galaxy. Estimation of cluster properties (age, mass, and extinction) was done through a comparison of their spectral energy distributions with simple stellar population models. We constructed the largest catalogue of stellar clusters and associations in this galaxy to-date, with ∼1800 sources with masses above ∼5000 M⊙ and ages younger than ∼300 Myr. In this Letter, we focus on the age distribution of the resulting clusters and associations. In particular, we explicitly test whether the age distributions are related with the ambient environment. Our results are in excellent agreement with previous studies of age distributions in the centre of the galaxy, which gives us confidence to expand out to search for similarities or differences in the other fields which sample different environments. We find that the age distribution of the clusters inside M83 varies strongly as a function of position within the galaxy, indicating a strong correlation with the galactic environment. If the age distributions are approximated as a power law of the form ${\frac{\mathrm{d} N}{\mathrm{d}t}}\propto t^{\zeta }$, we find ζ values between 0 and −0.62 (ζ ∼ −0.40 for the whole galaxy), in good agreement with previous results and theoretical predictions.
Effects of Lime‐Cooking on Carotenoids Present in Masa and Tortillas Produced from Different Types of Maize
Authors: Gutiérrez‐Uribe Janet A. , Rojas‐García Carlos , García‐Lara Silverio , Serna‐Saldivar Sergio O. 
Published: March 2014

ABSTRACTYellow and white maize kernels, masas, tortillas, and nejayote solids were analyzed in terms of lutein, zeaxanthin, cryptoxanthin, β‐carotene, and lipophilic antioxidant (AOX) capacity. The germplasm analyzed included two normal yellow maize, two high‐carotenoid genotypes, and one white for comparison purposes. In general, the yellow maize required 34% more lime‐cooking time compared with the white counterpart. Lime‐cooking significantly changed the extractability of carotenoids in masa and tortillas. No carotenoids were detected in the steepwater or nejayote. The lipophilic AOX activity increased 280‐fold from kernel to masa, but only 70% was retained in the baked tortillas. When masa was baked into tortillas, less than 10% of the carotenoids were retained because of the high temperatures used during baking. Interestingly, tortillas made with the maize kernels with the highest carotenoid content did not have the highest amount of these phytochemicals. Therefore, maize varieties should be evaluated based on the carotenoid content in finished food products instead of the amounts originally found in raw kernels.
Molecular and Chemical Characterization of a New Waxy Allele in Barley (Hordeum vulgare L.)
Authors: Hu Gongshe , Burton Charlotte , Hong Zonglie 
Published: March 2014

ABSTRACTBarley m38 mutant was selected for its high level of mixed‐linkage (1,3),(1,4)‐β‐d‐glucan (MLG) in the grain. This elevated level of MLG was found to be associated with decreased amylose accumulation as well as other chemical composition alterations. Molecular characterization results revealed m38 as a new allele of the Waxy gene, encoding an endosperm‐specific granule‐bound starch synthase I (GBSSI). Additional mapping data from amylose phenotype and GBSSI gene specific markers supported the conclusion of the GBSSI mutation in m38. The m38 locus contains a nucleotide alteration that would result in the substitution of glycine at position 263 with serine in the putative adenosine‐5′‐diphosphate‐glucose binding domain. This amino acid substitution alters loop structures on the exterior surface of the folded protein and may affect its enzyme activity. Characterizations of m38 in this report provide for a new allele of the Waxy gene and additional evidence of pleiotropic effects on other chemical components including increased MLG, fructans, and fats and decreased amylose and protein.
Industry classification and the efficiency of intra-industry information transfers
Authors: Y. Chung Dennis , Hrazdil Karel , Trottier Kim 
Published: March 2014

Purpose
– Motivated by recent studies that demonstrate the superiority of the Global Industry Classification System (GICS) relative to the Standard Industry Classification (SIC) system in capital market research, the authors revisit the stock market anomaly documented by Thomas and Zhang (TZ) (“Overreaction to intra-industry information transfers?” Journal of Accounting Research, Vol. 46, pp. 909-940) and analyze whether the anomaly based on SIC remains evident when intra-industry information transfers are based on the GICS. The paper aims to discuss these issues.

Design/methodology/approach
– The authors first replicate TZ and test whether stock prices of late announcers in response to earnings reported by early announcers in the same SIC industry are significantly related to subsequent price responses of late announcers to their own earnings reports. In the multivariate setting, the authors then evaluate whether the magnitude and significance of the overreaction anomaly changes under the more comprehensive GICS and across different time periods.

Findings
– The authors first confirm the over-reaction anomaly based on SIC as documented by TZ. Utilizing a larger sample of firms based on the GICS and extending TZ for a new time period, the authors then demonstrate that the overreaction anomaly disappears during recent years, a period that is characterized by markedly higher trading activity.

Research limitations/implications
– The findings provide new insights and contributions to the debate on whether or not market significantly misprices information transfers.

Originality/value
– The authors are first to utilize the GICS in evaluating intra-industry information transfers.
The relationship between organizational slack and innovation: revisited
Authors: Terry Mousa Fariss , Chowdhury Jaideep 
Published: March 2014

Purpose
– The slack-innovation relationship has interested scholars for years. The authors aim to delve into the impact of financial slack on firm innovation by replicating a classic study arguing that this relationship has an inverse U-shape.

Design/methodology/approach
– The sample consists of all US firms that were publicly traded between 1993 and 2011. The authors employ the standard econometrics methodology of panel regression with firm-fixed effect and time-fixed effect to estimate the regression equation of firm innovation on financial slack.

Findings
– The authors find that the relationship between financial slack and R&D investments is similar to that suggested by earlier authors, thus enhancing the generalizability of this important finding in management research. The authors also find that this relationship holds even during economic downturns.

Originality/value
– The authors replicate Nohria and Gulati's classic study by considering the impact of slack on innovation. The authors also move away from survey data, as used by Nohria and Gulati. The authors utilize actual firm-level data for a large sample of US publicly traded firms from 1993 to 2011, thus enhancing the generalizability of these findings.

Authors: Tešanovic Dragan , Krasavcic Milovan , Miro Kalenjuk Bojana , Portic Milijanko , Gagic Snježana 
Published: March 2014

Purpose
– The aim of this paper is to determine the sensory quality of food in restaurants by professional food evaluators and to research the impact of education, age and number of employees on the quality of food.

Design/methodology/approach
– In the first phase five trained food tasters evaluated the sensory quality of food. In the second phase, the analysis of the structure of employees was done by establishing their level of education, age and number of employees. In the third phase the regression and correlation analysis was done with the aim to establish the impact of the level of education, age and number of employees on the sensory quality of food.

Findings
– The sensory evaluation has shown that the evaluated food is of moderate quality. Correlation matrix has shown that the education level of employees has a high impact on the sensory quality of food. There is a correlation between the number of employees, their age and their education.

Practical implications
– Obtained results are the indicators of the quality of food in restaurants in the region and they can serve for the improvement of quality. They have shown that education and staff training can contribute to a better quality of food. Established methodology can also contribute to the practical evaluation of quality.

Originality/value
– This paper is reflected on the specific application of methodology of the sensory analysis of food in restaurants. The paper pointed to the impact of employees on the sensory quality of food by statistical methods. Statistical results which point to the great impact of the level of education of employees on the sensory quality of food in restaurants are particularly valuable.
Physicomechanical, phytochemical, volatile compounds and free radical scavenging properties of eight pomegranate cultivars and classification by principal component and cluster analyses
Authors: Amos Fawole Olaniyi , Linus Opara Umezuruike 
Published: March 2014

Purpose
– The purpose of this study was to characterize fruit properties of pomegranate cultivars grown in South Africa in order to provide information to assist in selecting cultivars for food and industrial purposes, as well as to optimize postharvest handling and processing.

Design/methodology/approach
– The physical, textural and chemical properties as well as volatile profile and free radical scavenging capacity of eight cultivars (cvs “Acco”, “Arakta”, “Bhagwa”, “Ganesh”, “Herskawitz,” “Molla de Elche”, “Ruby”, and “Wonderful”) were quantified to demonstrate the diversity among the characters of the commercially grown cultivars.

Findings
– Statistically significant differences were found between cultivars for most of the evaluated characters, primarily highlighting the genetic diversity among the cultivars. The classification of fruit cultivars based on quality traits (such as size, texture, colour, soluble solids, acidity, juiciness and phenolics) showed the great potential of the cultivars for processing and fresh market. The relationship among these quality traits was analysed by principal component analysis (PCA) resulting in the separation of the investigated cultivars into two groups (cluster 1=Ruby, Arakta and Ganesh; Class 2=Bhagwa, Acco and Herskawitz) and two ungrouped cultivars (Molla de Elche and Wonderful). Specific understanding about quality traits of each cultivar was established using the correlation coefficients obtained.

Originality/value
– This study provides valuable fundamental information that can be useful for commercial and industrial purposes, as well as the development of optimal postharvest handling and processing parameters for the investigated South African grown pomegranate cultivars.
A framework for investigating blended learning effectiveness
Authors: Wong Lily , Tatnall Arthur , Burgess Stephen 
Published: March 2014

Purpose– The move towards “blended learning”, consisting of a combination of online and face-to-face teaching, continues to gain pace in universities around the world. It is important, however, to question the quality of this learning. The OECD has made use of a model of “Readiness, Intensity and Impact” for investigating the adoption and use of eBusiness technologies. The purpose of this paper is to propose a framework, based on this model and adapted for blended learning, to assess the readiness, intensity of adoption and impact on blended learning offerings. The framework is tested via a description of how one university has adopted and used blended learning, and investigates the quality of the learning from this approach.Design/methodology/approach– The framework is tested via a case study involving the assessment of a blended learning approach to the delivery of a first-year undergraduate accounting unit at Victoria University, Australia. Various approaches to delivery are assessed over a two-year period. The results are drawn from a survey specifically designed to identify students’ attitudes towards blended learning.Findings– Despite having three new online options readily available for students to access, there was strong support for face-to-face delivery methods. In relation to the framework, the assessment suggested that certain aspects of the university's blended learning approach could be investigated further (particularly student readiness for different blended learning options and an overall assessment of the impact of a blended approach), to provide a more holistic view of the readiness to adopt and impact of the blended learning offerings.Originality/value– The value of this contribution lies in the development of a unique framework to assess the impact of blended learning approaches from the viewpoint of student readiness and intensity of separate delivery approaches – whilst maintaining the need to evaluate the effectiveness of blended learning as an overall package.
