Replication as a Verification Technique in Survey Research: A Paradigm

Replication is one of several methodological techniques that contributes to the verification of survey research data. A critique of the literature on replication reveals that limited systematic attention has been given to its various functions in the process of verification. A replication paradigm is formulated to clarify terminology and functions. The paradigm consists of four major replication types: retest, internal, independent, and theoretical. These are analyzed and illustrated by published replication studies. An argument is offered in favor of the increased use of replication in survey research.     

On the estimation of serial correlation in Markov-dependent production processes

In this paper, we present a study about the estimation of the serial correlation for Markov chain models which is used often in the quality control of autocorrelated processes. Two estimators, non-parametric and multinomial, for the correlation coefficient are discussed. They are compared with the maximum likelihood estimator [U.N. Bhat and R. Lal, Attribute control charts for Markov dependent production process, IIE Trans. 22 (2) (1990), pp. 181–188.] by using some theoretical facts and the Monte Carlo simulation under several scenarios that consider large and small correlations as well a range of fractions (p) of non-conforming items. The theoretical results show that for any value of p≠0.5 and processes with autocorrelation higher than 0.5, the multinomial is more precise than maximum likelihood. However, the maximum likelihood is better when the autocorrelation is smaller than 0.5. The estimators are similar for p=0.5. Considering the average of all simulated scenarios, the multinomial estimator presented lower mean error values and higher precision, being, therefore, an alternative to estimate the serial correlation. The performance of the non-parametric estimator was reasonable only for correlation higher than 0.5, with some improvement for p=0.5.     

Developing a Brief Suicide Prevention Intervention and Mobile Phone Application: A Qualitative Report

Suicide is the second leading cause of death among youth and has become a serious public health problem. There has been limited research on strategies to decrease the likelihood of reattempt in adolescents. As phase one of a treatment development study, clinicians, parents, and adolescents participated in qualitative interviews in order to gain new perspectives on developing a targeted intervention and a safety plan phone application for suicide prevention. Participants indicated that transition of care, specific treatment targets, and safety planning were important parts of treatment. In addition, all participants endorsed the use of a smartphone application for these purposes.     

Biopharmaceutical and chemical firms’ R&D disclosure,and cost of equity: The impact of the regulatory regime

Based on the proprietary costs theory, this paper aims to survey whether the regulatory regime (mandatory versus voluntary) of research and development (R&D) narrative disclosures impacts, by the means of a reduced information asymmetry, on the cost of equity capital. In order to construct a disclosure index to investigate the extent and the comprehensiveness of R&D information, the methodology adopted was the content analysis of 77 biopharmaceutical and chemical listed companies’ management reports from eight Western European countries across the period 2005–2009. Hence, we obtained an (unbalanced) panel data of 309 observations. The cost of capital has subsequently been regressed on the disclosure index. Results confirm a larger amount of R&D disclosures whereas information is more regulated, but they do not confirm an inverse relation with the cost of capital.     

Risk Perception and Technological Development at a Societal Level

This article tests the hypothesis that the exposure to the threat to societies posed by the introduction of new technologies is associated with a normalization of risk perception. Data collected in 2000 by the International Social Survey Programme (ISSP) on environmental issues were used to explore this hypothesis. Representative samples from 25 countries were employed to assess the national levels of perceived threat to the environment associated with a series of technologies and activities. These values were correlated with economic indicators (mainly from the World Bank) of the diffusion of each of the technologies or activities in each country. Results indicate a negative association of risk perception with the level of technological prevalence (societal normalization effect) and a positive association with the rate of growth of the technology (societal sensitivity effect). These results indicate that the most acute levels of perceived environmental risk are found in those countries where the level of technological prevalence is low but where there has recently been substantial technological development. Environmental awareness is a mediator of the relationship between risk perception and the indices of technological diffusion. This result means that: (1) societal normalization of risk is not a direct consequence of prevalence of the technology, but is driven by awareness of technological development and that (2) societal sensitivity to risk is associated with lower levels of environmental awareness.     

Neighbourhood in a high rise, high density city: some observations on contemporary Hong Kong

Most of the contemporary literature on the neighbourhood comes from US or European sources where there are sharp contrasts with East Asian cities in terms of the physical form, residential densities and in relation to ideas of community and kinship. This paper reports on a study carried out in Hong Kong which was designed to explore the extent to which western preoccupations with neighbourhood resonate in a high rise, high density Chinese city. As a precursor to a larger scale study interviews were carried out with fifteen individuals in three contrasting locations: a New Town estate, an older, inner city area and a middle class housing estate. The interviews explored inter alia neighbourhood perceptions, ideas of community, sense of belonging and sense of place among contemporary Hong Kong residents. When Yuan Ssu became Confucius' steward he was given nine hundred measures of grain, which he declined. The Master said, ‘Can you not find a use for it in helping the people in your neighbourhood?’ (The Analects, Book VI).     

Aversive Peer Experiences on Social Networking Sites: Development of the Social Networking‐Peer Experiences Questionnaire (SN‐PEQ)

Cyber victimization is an important research area, yet little is known about aversive peer experiences on social networking sites (SNSs), which are used extensively by youth and host complex social exchanges. Across samples of adolescents (n = 216) and young adults (n = 214), we developed the Social Networking‐Peer Experiences Questionnaire (SN‐PEQ) and examined its psychometric properties, distinctiveness from traditional peer victimization measures, and associations with internalized distress. The SN‐PEQ demonstrated strong factorial invariance and a single‐factor structure that was distinct from other forms of peer victimization. Negative SNS experiences were associated with youths' symptoms of social anxiety and depression, even when controlling for traditional peer victimization. Findings highlight the importance of examining the effects of aversive peer experiences that occur via social media.     

The limits of participatory democracy and the inclusion of social movements in local government

ABSTRACT

This paper examines the decentralisation of decision-making processes in local government. Empirically, I analyse how Brazilian housing movements are included in participatory processes by examining the ways in which participatory models integrate social movements in spaces of decision-making. I argue that the rules and focus on incremental policy-making limits the participation of social movements. Findings suggests that unequal power structures at local councils, barriers to the participation of citizens, and the lack of transparency of government decisions all prevent social movements from having a more influential voice in decision-making. Although previous studies in Brazil examined the integration of citizens in government institutions, this paper contributes to the literature in two ways: firstly, it provides new evidence on the impact of decentralisation in local government. Secondly, by examining the attitudes of housing council members towards popular political participation, it provides new insights into the limits of decentralisation and participatory governance in contemporary Brazil.
