House price indexes and cyclical behavior
Authors: Bianconi Marcelo , Yoshino Joe A. 
Published: February 2013

PurposeThe purpose of this paper is to use data on new apartment offerings in the municipality of Sao Paulo, Brazil to illustrate its main claim that the hedonic direct method using time dummies as well as the simple average method include cyclical behavior of observables and non‐observables in a house price index that may overestimate or underestimate the actual change in house prices, well beyond the composition effects.Design/methodology/approachThe paper proposes the use of alternative characteristics hedonic functions to compute alternative Laspeyres house price indexes that differentiate the sources of observable shocks in the index. The decomposition allows for the inclusion of level and cyclical behavior of sets of aggregate variables into the index.FindingsThe appropriate house price index should filter out real shocks that potentially affect the real estate sector. An index should capture nominal variation and incorporating real variation biases the measurement. Thus, the index is intended and able to buffer the bias spillover into the rest of economy. In the limited sample from the city of Sao Paulo, Brazil, the main finding is that real shocks and US foreign shocks give an upward bias in the house price index, while nominal shocks give mostly a downward bias. Real shocks make the index incorporate gains that should not be incorporated into the index, thus providing a noisy picture of the nominal variation in house prices.Originality/valueThe key contribution of this paper is to provide a framework for the construction of a house price index that filters out real shocks that potentially affect the real estate sector. An index should capture nominal variation and incorporating real variation biases the measurement. Those biases can spillover to the rest of the economy is a detrimental way. Thus, the index is intended and able to buffer the bias spillover into the rest of economy.
Household attributes and the future demand for retirement housing
Authors: Ball Michael , Nanda Anupam 
Published: February 2013

PurposeAgeing populations provoke the question of how much bespoke housing should be provided for the elderly. Older people are generally reluctant to move but as they age health circumstances may encourage moves into specialised accommodation. This paper aims to report on an exercise in estimating the future demand for specialised independent living housing and the extent to which that demand will be for owner occupied accommodation or renting, using data for England.Design/methodology/approachThe most important predictor of demand for specialised housing is the extent of the requirement for at least some degree of long‐term care due to loss of mobility. Therefore, the forecast is formulated around a behaviour‐based model centred on demographic, personal physical mobility and housing tenure factors.FindingsThe forecasts indicate a substantial increase in demand, growing at a faster rate than the population as a whole. If supply does not rise to meet these demands, serious problems arise in the quality of life of, and cost of caring for, older people with implications for health care and social services. Moreover, some of the greatest growth is going to be amongst those aged 75 to 84 and amongst the very old 85+ group.Research limitations/implicationsThe forecast is based on ELSA estimates. Data on activity and ageing are available from the English Longitudinal Survey of Ageing's (ELSA) Wave 4 2008 data set.Practical implicationsThe implication is that in the future far more provision of housing for the elderly will have to take place in the private sector. However, the market provision of specialised retirement housing is likely to be very inadequate for predicted needs. A significant cause of this is a chronic planning‐induced land shortage which keeps the price of retirement accommodation high.Social implicationsThe continuing shortage of specialised housing will mean that hundreds of thousands of the elderly will continue to live in their existing accommodation when bespoke property would better suit their needs. This will further exacerbate general housing shortages, especially as the empty nester elderly do often own substantial family homes. It will also put pressures on care home sector because, in the absence of an appropriate intermediate stage, more will be pushed into care.Originality/valueIt could be argued that the assumptions made in this forecasting exercise contain a number of essentially arbitrary statements. But that is to miss the point of this exercise, which is to suggest that a large potential demand exists on plausible estimates of who might benefit from living in specialised retirement housing.
My place is not your place – different place brand knowledge by different target groups
Authors: Zenker Sebastian , Beckmann Suzanne C. 
Published: February 2013

PurposeCities increasingly compete with each other for attracting tourists, investors, companies, or residents. Marketers therefore focus on establishing the city as a brand, disregarding that the perception and knowledge of a city differ dramatically between the target audiences. Hence, place branding should emphasize much more the perceptions of the different target groups and develop strategies for advanced place brand management. The aim of this paper is to assess the important discrepancies between the city brand perceptions of different target groups with the help of network analysis.Design/methodology/approachIn two empirical studies, the important discrepancies between the city brand perceptions of different target groups are assessed with the help of network analysis. Study 1 consists of 40 qualitative in‐depth‐interviews and study 2 uses an online qualitative open‐ended‐question survey with 334 participants.FindingsStructural differences for the city brand perceptions of two different target groups and the differences between perceptions of an external and internal target group are highlighted. The results and the managerial implications for place marketers are discussed.Research limitations/implicationsThe study investigates the brand associations for the city of Hamburg brand with two target groups and this limits the generalizability of the results. However, the focus was on measuring for the first time the difference in the place brand perception of different target group and the results helps to understand how an advanced place brand management could deal with this challenge.Originality/valuePlace branding is increasingly popular in urban management. This paper highlights the challenge of diverse target audiences in this process and discusses implication for an advanced place brand management.

Authors: Porfírio Guimarães Pedro 
Published: February 2013

PurposeThe purpose of this article is to critically review some interventions made in Portugal through Commercial Urbanism Programmes. These public interventions, with the objective of revitalizing city centres and modernizing the retail sector, culminated with the development of town centre management schemes. The paper also intends to analyze how these interventions have been evaluated.Design/methodology/approachThe paper contains a brief literature review which clarifies why city centres went into decline and why we should apply positively discriminatory policies in order to revitalize them. Second, the paper describes the main aspects of the public programmes and town centre management in the Portuguese context. After, the paper identifies the main aspects that concern the evaluation of impacts. The paper approaches the difficulties, gaps and importance of evaluation. In the last point the paper draws some final considerations.FindingsThis research identifies the main measures implemented in Portugal in order to overcome the decline felt in city centres. Also it recognizes some gaps in the interventions, mainly regarding the lack of concern for local specifications. It also recognizes the difficulty in establishing a proper evaluation and identifies different ways of collecting data, usable for an evaluation.Originality/valueThis paper helps clarify the process of public intervention in city centres in Portugal. Beside that it sheds some light about the importance of evaluation and how data can be collected.

PurposeThis study aims to analyse the gender composition of the 99 most liquid Brazilian companies listed in the Brazilian stock exchange (BM&FBovespa) in 2011. It proposes a discussion about gender inequality in Brazilian companies and provides data, made available for the first time to national and international literature, on gender composition in Brazilian boards.Design/methodology/approachThis is a quantitative study, whose data were collected from the Annual Report of Corporate Governance of Listed Companies 2011 prepared by the Capital Aberto magazine on the makeup of the boards of the 100 most liquid Brazilian publicly traded companies. Descriptive multivariate regression tests were carried out to refine these findings.FindingsThe results show that only 5.4 per cent of the positions in the boards of these companies are occupied by women. Firms that have been listed for longer in the stock market and have more seats in their boards are more likely to have women directors in these boards, suggesting gender inequality in the 99 companies surveyed.Research limitations/implicationsThis study has a limitation with regards to the type of female board members in the sample. In other words, the authors were unable to determine if they were external or internal to the companies.Practical implicationsThe study discusses gender inequality in Brazilian companies and contributes to the debate on a governmental proposal to adopt quota legislation to increase the number of women in boards of directors.Originality/valueThis study fulfils an identified need to know more about the gender composition of Brazilian boards.

Published: February 2013

PurposeWith an established association between post‐traumatic stress disorder (PTSD) and the perpetration of intimate partner violence (IPV), evaluating the effectiveness of emerging integrated treatments for dual substance use and partner violent behavior in individuals with a significant trauma history may serve to improve treatment outcomes for clients with axis I psychopathology. The purpose of this paper is to examine the association between sub‐clinical trauma, treatment compliance, and recidivism in a sample of male, substance dependent IPV offenders.Design/methodology/approachThe described investigation utilized violence perpetration, substance use, and trauma data collected during a larger, randomized control treatment evaluation study. Data were collected from 56 participants at four time points throughout treatment.FindingsParticipants with a significant trauma history comprised 33.9 percent of the sample and demonstrated poorer treatment attendance, as well as heightened partner violence recidivism throughout treatment, as compared to participants who denied experiencing a significant trauma. This finding held across participants receiving substance treatment only and combined treatment addressing substance use and violence.Practical implicationsIPV perpetrators often have a trauma history themselves. The association between sub‐clinical trauma symptomatology and poor treatment outcomes calls for the adaptation of current partner violence intervention models to accommodate the large subset of clients who suffer from either sub‐clinical or clinically significant trauma.Originality/valueThis paper is the first to address the potential influence of sub‐clinical trauma on the integrated treatment of substance use and partner violence within a forensic sample. Suggestions are offered to adapt existing treatment models to accommodate dual diagnosed clients.
Does simulation enhance undergraduate psychiatric nursing education? A formative assessment
Authors: Maruca Annette T. , Diaz Desiree A. 
Published: February 2013

PurposeAlcohol withdrawal syndrome (AWS) is a serious condition that can result in death if it is not recognized and treated appropriately. A high fidelity simulation scenario on AWS was created for psychiatric nurses in an educational setting that focused on the recognition of alcohol withdrawal, implementation of the Clinical Institute Withdrawal Assessment (CIWA) and initiation of appropriate treatment and management of AWS.Design/methodology/approachA formative assessment teaching strategy was used to evaluate the development and implementation of a high fidelity simulation (HFS) on alcohol withdrawal syndrome. The HFS was part of a baccalaureate undergraduate psychiatric nursing education designed to reinforce classroom theory and clinical application. Results were measured using a self‐report survey completed by students that focused on the details of content and performance.FindingsFeedback from the 38 nursing students who evaluated the HFS was overall positive. Survey results showed that the HFS scenario reinforced the classroom theory on addiction and mental disorders while translating and supporting student's learning to clinical practice. The HFS provided opportunity for students to practice skills when they had not had this experience during the clinical rotation. Only four students felt uncomfortable with decision making and initiating the CIWA scale after the HFS.Originality/valueThere is a gap in the development and use of standardized simulations for mental health and substance abuse scenarios as a teaching strategy in nursing programs. The results of this study supported using HFS as an educational strategy and set the stage for future complex simulations such as dual diagnosis and clients with comorbidities.

AbstractVitiligo is an acquired pigment disorder in which depigmented macules result from the loss of melanocytes from the involved regions of skin and hair. The color dissimilarity on the cosmetically sensitive regions frequently induces quality of life impairment and high willingness to pay for treatment in patients with vitiligo. The Vitiligo Japanese Task Force was organized to overcome this situation and to cooperate with the Vitiligo Global Issues Consensus Conference. This guideline for the diagnosis and treatment of vitiligo in Japan is proposed to improve the circumstances of Japanese individuals with vitiligo. Its contents include information regarding the diagnosis, pathogenesis, evaluation of disease severity and effectiveness of treatment, and evidence‐based recommendations for the treatment of vitiligo. The therapeutic algorithm based on the proposed recommendation is designed to cure and improve the affected lesions and quality of life of individuals with vitiligo.
Contrasting leaf trait scaling relationships in tropical and temperate wet forest species
Authors: Xiang Shuang , Reich Peter B. , Sun Shucun , Atkin Owen K. 
Published: February 2013

Summary

We investigated whether plants adapted to thermally contrasting environments (e.g. tropical‐temperate habitats) exhibit inherent differences in leaf trait scaling relationships.

Thirteen tropical and 12 temperate species (all characteristic of wet forests) were grown in a glasshouse (25/20 °C day/night). A range of leaf traits were quantified, including mass‐based leaf nitrogen [N], mass per unit area (LMA), light‐saturated photosynthesis (A) and respiration (Rdark).

Average area‐ and mass‐based rates of net CO2 exchange were higher in the temperate species, compared to their tropical counterparts. Average leaf [N] and LMA values were also higher in temperate species than in their tropical counterparts.

The higher LMA in the metabolically more active temperate species was the most striking contrast to the patterns and predictions of the GLOPNET leaf trait data base, and was associated with different elevations (i.e. y‐axis intercepts) but not slopes of bivariate trait scaling relationships. As expected, mass‐based rates of A and Rdark scaled positively with increasing [N] and negatively with increasing LMA in both tropical and temperate species. No differences were found between temperate and tropical species groups in terms of log‐log scaling relationships linking A and Rdark to N. However, at any given LMA, mass‐based values of [N], A and Rdark were all higher in the temperate species than in their tropical counterparts.

Underpinning higher A in temperate species was a higher capacity for carboxylation (Vcmax) and RuBP regeneration (Jmax), with Jmax:Vcmax being greater in temperate species.

In conclusion, our results suggest that as a consequence of greater overall N investment as well as greater proportional N investment in metabolic capacity, cool‐adapted temperate wet forest species exhibit higher photosynthetic and respiration rates than their warm‐adapted tropical counterparts when compared in a common environment.
Non‐linear prestack seismic inversion with global optimization using an edge‐preserving smoothing filter
Authors: Zhe Yan , Hanming Gu 
Published: February 2013

ABSTRACTEstimating elastic parameters from prestack seismic data remains a subject of interest for the exploration and development of hydrocarbon reservoirs. In geophysical inverse problems, data and models are in general non‐linearly related. Linearized inversion methods often have the disadvantage of strong dependence on the initial model. When the initial model is far from the global minimum, inversion iteration is likely to converge to the local minimum. This problem can be avoided by using global optimization methods.In this paper, we implemented and tested a prestack seismic inversion scheme based on a quantum‐behaved particle swarm optimization (QPSO) algorithm aided by an edge‐preserving smoothing (EPS) operator. We applied the algorithm to estimate elastic parameters from prestack seismic data. Its performance on both synthetic data and real seismic data indicates that QPSO optimization with the EPS operator yields an accurate solution.
Imaging by forward propagating the data: theory and application
Authors: Zuberi Akbar , Alkhalifah Tariq 
Published: February 2013

ABSTRACTThe forward (modelled) wavefield for conventional reverse time migration (RTM) is computed by extrapolating the wavefield from an estimated source wavelet. In the typical case of a smooth subsurface velocity, this wavefield lacks the components, including surface reflections, necessary to image multiples in the observed data. We, instead, introduce the concept of forward propagating the recorded data, including direct arrivals, as part of RTM. We analyse the influence of the main components of the data on the imaging process, which include direct arrivals, primaries and surface‐related multiples. In our RTM methodology, this implies correlating the forward extrapolated recorded data wavefield with its reversely extrapolated version prior to applying the zero‐lag cross‐correlation imaging condition. The interaction of the data components with each other in the cross‐correlation process will image primaries and multiples, as well as introduce cross‐talk artefact terms. However, some of these artefacts are present in conventional RTM implementation and they tend to be relatively weak. In fact, for the surface seismic experiment, forward propagating the direct arrivals is almost equivalent to forward propagating a source and it tends to contribute the majority of the data imaging energy. In addition, primaries and multiples recorded in the data become multiples of one higher order. Forward propagating the recorded data to recreate the source will relieve us from the requirement of estimating the source function. It will also include near‐surface information necessary to improve the image in areas with near‐surface complexity. Data from a simple synthetic layered model, as well as the Marmousi model, are used to demonstrate some of these features.
Does cooperation increase helpers' later success as breeders? A test of the skills hypothesis in the cooperatively displaying lance‐tailed manakin
Authors: DuVal Emily H. 
Published: February 2013

Summary

Experience improves individual performance in many tasks. Pre‐breeding cooperation may provide important experience that improves later success as a breeder, offering one compelling explanation for why some individuals delay reproduction to help others breed (the ‘skills hypothesis’). However, confounding effects of age, quality and alternative selective benefits have complicated rigorous tests of this hypothesis.
Male lance‐tailed manakins perform cooperative courtship displays involving partnerships between unrelated alpha and beta males, and alphas monopolize resulting copulations. Beta males therefore do not receive immediate direct or indirect fitness benefits, but may gain skills during cooperation that increase their later success as an alpha. To date, however, the effect of cooperative experience on later success as a breeder has never been tested in any cooperatively displaying taxon.
The effects of prior cooperative experience on reproductive success of alpha lance‐tailed manakins were analysed in a mixed model framework using 12 years of information on cooperative experience and annual and lifetime genetic reproductive success for 57 alpha males. Models included previously identified effects of age and alpha tenure. Individual‐level random effects controlled for quality differences to test for an independent influence of beta experience on success.
Males accumulated up to 5 years of beta experience before becoming alphas, but 42·1% of alphas had no prior beta experience. Betas became alphas later in life, and experienced significantly lower reproductive success in their final year as alpha than males that were never beta, but did not have higher lifetime success or longer alpha tenures. Differences in patterns of annual siring success were best explained by age‐dependent patterns of reproductive improvement and senescence among alphas, not beta experience.
Cooperative experience does not increase relative breeding success for male lance‐tailed manakins. Importantly, beta cooperation seems to be an alternative reproductive tactic that yields fitness payoffs equivalent to a non‐cooperative route to alpha status, if population growth rate is stable.
