Defective models induced by gamma frailty term for survival data with cured fraction

In this paper, we propose a defective model induced by a frailty term for modeling the proportion of cured. Unlike most of the cure rate models, defective models have advantage of modeling the cure rate without adding any extra parameter in model. The introduction of an unobserved heterogeneity among individuals has bring advantages for the estimated model. The influence of unobserved covariates is incorporated using a proportional hazard model. The frailty term assumed to follow a gamma distribution is introduced on the hazard rate to control the unobservable heterogeneity of the patients. We assume that the baseline distribution follows a Gompertz and inverse Gaussian defective distributions. Thus we propose and discuss two defective distributions: the defective gamma-Gompertz and gamma-inverse Gaussian regression models. Simulation studies are performed to verify the asymptotic properties of the maximum likelihood estimator. Lastly, in order to illustrate the proposed model, we present three applications in real data sets, in which one of them we are using for the first time, related to a study about breast cancer in the A.C.Camargo Cancer Center, São Paulo, Brazil.     

Respect in intergenerational relationships: Young adult women’s motivations

Care and respect are two sides of the same coin, yet very little is known about respect shown by younger women in relation to people aged 60 and older. This study sets out to explore what motivates young adult women to respect older people. Twenty-five post-graduate women from a tertiary education institution in South Africa participated in the Mmogo-method®, a projective visual data-collection method, to produce textual and visual data. These were analysed using sequential and visual analysis. Findings reported combinations of motivational types for respect of older people, on a continuum from extrinsic (socialised normative values) to intrinsic (personal choice and empathy), and from conditional to unconditional, namely: extrinsic/conditional; extrinsic/unconditional; self-motivated/conditional and self-motivated/unconditional. Respect as an impact on relational interactions between people is either constructive and encouraging or damaging and disparaging. Interpersonal risks are associated with motivation and this could affect future interactions and manifestations of intergenerational respect.     

The concept of a child within sub‐Saharan African migrant homes: Reconciling culture and child rights

As international migration increases, the Australian socio‐cultural and political context in which sub‐Saharan African migrant families are settling is causing tension between traditional sub‐Saharan African migrant definitions of child and childhood experiences and host nation definitions particularly when compared with the child protection system. This paper seeks to explore and highlight the fundamental values and differences that determine perceptions and treatment of children within traditional sub‐Saharan African communities. Using a qualitative design, this study was influenced by acculturation theory. Four major themes emerged from the analysis: (a) culture and the sub‐Saharan African child, (b) moulding good children, (c) family functioning and relationships, and (d) host context: perceptions of Australian mainstream parenting. The study found that in order to successfully make decisions that are in the best interest of sub‐Saharan African migrant children that come to the attention of the child protection system, discussions about children rights can only yield good outcomes when the child's socio‐cultural environment is considered.     

Sliders,visual analogue scales,or buttons: Influence of formats and scales in mobile and desktop surveys

ABSTRACT

In an experiment dealing with the use of personal computer, tablet, or mobile, scale points (up to 5, 7, or 11) and response formats (bars or buttons) are varied to examine differences in mean scores and nonresponse. The total number of “not applicable” answers does not vary significantly. Personal computer has the lowest item nonresponse, followed by mobile and tablet, and a lower mean score than for mobile. Slider bars showed lower mean scores and more nonresponses than buttons, indicating that they are more prone to bias and difficult in use. Sider bars, which work with a drag-and-drop principle, perform worse than visual analogue scales working with a point-and-click principle and buttons. Five-point scales have more nonresponses than eleven-point scales. Respondents evaluate 11-point scales more positively than shorter scales.     

Measuring organizational effectiveness in information and communication technology companies using item response theory

The aim of this paper is to measure the effectiveness of the organizations Information and Communication Technology (ICT) from the point of view of the manager, using Item Response Theory (IRT). There is a need to verify the effectiveness of these organizations which are normally associated to complex, dynamic, and competitive environments. In academic literature, there is disagreement surrounding the concept of organizational effectiveness and its measurement. A construct was elaborated based on dimensions of effectiveness towards the construction of the items of the questionnaire which submitted to specialists for evaluation. It demonstrated itself to be viable in measuring organizational effectiveness of ICT companies under the point of view of a manager through using Two-Parameter Logistic Model (2PLM) of the IRT. This modeling permits us to evaluate the quality and property of each item placed within a single scale: items and respondents, which is not possible when using other similar tools.     

Accessibility for all: going from theory to practice

The present work demonstrates, through a case study, the importance of theoretical knowledge in practical application of spatial accessibility in order to guarantee equal conditions for all people in the movement and use of space. Initially there was a literature review on the accessibility of space and how design in a accessible way. Next, we show one makeover proposal in one public school that wants to provide access to people with disabilities. This makeover was done and so we could evaluate the buildings changes through the method of accompanied walk with two people. Finally we present the main results and discussions.     

Romaphobia and the media: mechanisms of power and the politics of representations

ABSTRACT

This special issue of Identities, entitled ‘Romaphobia and the media’, examines entrenched and ongoing media coverage of Roma, Gypsy and Traveller people across Europe. The focus is on how the media problematises the Roma, how it constructs a ‘conceptual map’ about Roma people and what this tells us about the societies we live in. This special issue includes five academic articles all examining the constructions and stereotypes used in the media in various formats and European countries. After these academic articles, this special issue then deviates from the normal journal structure by including three commentary pieces from professionals from varying Roma backgrounds to give their views and experiences on how they tackle Romaphobia and the media. The inclusion of these commentary pieces are very powerful in offering a perspective of active interventions and resistance that we should not forget amidst the depressing continued circulation of racialised stereotypes.     

Comparing income poverty gap and deprivation on social acceptance: A mediation model with interpersonal communication and social support

In many developed countries or regions, wide income disparities increase the difficulty in reducing poverty. In their day‐to‐day lives, poor people often feel less accepted by the society. The failures in communicating with social groups and receiving social support lead to negative consequences on individual well‐being and higher level of social exclusion. Based on the debate upon alternative approaches to conceptualizing and operationalizing poverty, this study attempts to verify a mediation model with data from a household survey (N = 1,202) in Hong Kong. The results of structural equation modelling reveal that deprivation is a more powerful indicator than income poverty for specifying the negative relations of poverty with interpersonal communication, social support, and social acceptance; the negative impact of deprivation on social acceptance can be reduced by two significant mediators of interpersonal communication and social support. The results are discussed in terms of directions for future research and policy and welfare intervention.     

Contesting disabling conditions of life in the Global South: disability activists’ and service providers’ experiences in Guyana

This article addresses an important gap in our understanding of issues of impairment and disability, namely challenges facing disabled activists and service providers in the majority world context of the developing nation of Guyana. The article argues that developing a southern standpoint on impairment, disability, disability activism and service provision requires a reframing of disability issues as matters of distributive justice and not only human rights. Challenges facing disability activists and service providers in Guyana included trying to combat internalized ableism, financial and cultural barriers to political engagement and visibility, tensions in claiming or rejecting disabled identities and difficulties in accessing foreign aid funding for disability initiatives. The article concludes by stressing the importance of rethinking how we do disability studies so that it allows critical analysis of the dynamics of a global capitalist corporeal class order in the context of the majority world.
