Controlling Privacy Loss in Survey Sampling (Working Paper)

Social science and economics research is often based on data collected in surveys. Due to time and budgetary constraints, this data is often collected using complex sampling schemes designed to increase accuracy while reducing the costs of data collection. A commonly held belief is that the sampling process affords the data subjects some additional privacy. This intuition has been formalized in the differential privacy literature for simple random sampling: a differentially private mechanism run on a simple random subsample of a population provides higher privacy guarantees than when run on the entire population. In this work we initiate the study of the privacy implications of more complicated sampling schemes including cluster sampling and stratified sampling. We find that not only do these schemes often not amplify privacy, but that they can result in privacy degradation.Comment: Working paper, 7 page

The Effect of Interviewer Experience, Attitudes, Personality and Skills on Respondent Co-operation with Face-to-Face Surveys

This paper examines the role of interviewers' experience, attitudes, personality traits and inter-personal skills in determining survey co-operation, conditional on contact. We take the perspective that these characteristics influence interviewers' behaviour and hence influence the doorstep interaction between interviewer and sample member. Previous studies of the association between doorstep behaviour and co-operation have not directly addressed the role of personality traits and inter-personal skills and most have been based on small samples of interviewers. We use a large sample of 842 face-to-face interviewers working for a major survey institute and analyse co-operation outcomes for over 100,000 cases contacted by those interviewers over a 13-month period. We find evidence of effects of experience, attitudes, personality traits and inter-personal skills on co-operation rates. Several of the effects of attitudes and inter-personal skills are explained by differences in experience, though some independent effects remain. The role of attitudes, personality and skills seems to be greatest for the least experienced interviewers

Avoiding disclosure of individually identifiable health information: a literature review

Achieving data and information dissemination without arming anyone is a central task of any entity in charge of collecting data. In this article, the authors examine the literature on data and statistical confidentiality. Rather than comparing the theoretical properties of specific methods, they emphasize the main themes that emerge from the ongoing discussion among scientists regarding how best to achieve the appropriate balance between data protection, data utility, and data dissemination. They cover the literature on de-identification and reidentification methods with emphasis on health care data. The authors also discuss the benefits and limitations for the most common access methods. Although there is abundant theoretical and empirical research, their review reveals lack of consensus on fundamental questions for empirical practice: How to assess disclosure risk, how to choose among disclosure methods, how to assess reidentification risk, and how to measure utility loss.public use files, disclosure avoidance, reidentification, de-identification, data utility

Integration of HIV Care with Primary Health Care Services: Effect on Patient Satisfaction and Stigma in Rural Kenya.

HIV departments within Kenyan health facilities are usually better staffed and equipped than departments offering non-HIV services. Integration of HIV services into primary care may address this issue of skewed resource allocation. Between 2008 and 2010, we piloted a system of integrating HIV services into primary care in rural Kenya. Before integration, we conducted a survey among returning adults ≥18-year old attending the HIV clinic. We then integrated HIV and primary care services. Three and twelve months after integration, we administered the same questionnaires to a sample of returning adults attending the integrated clinic. Changes in patient responses were assessed using truncated linear regression and logistic regression. At 12 months after integration, respondents were more likely to be satisfied with reception services (adjusted odds ratio, aOR 2.71, 95% CI 1.32-5.56), HIV education (aOR 3.28, 95% CI 1.92-6.83), and wait time (aOR 1.97 95% CI 1.03-3.76). Men's comfort with receiving care at an integrated clinic did not change (aOR = 0.46 95% CI 0.06-3.86). Women were more likely to express discomfort after integration (aOR 3.37 95% CI 1.33-8.52). Integration of HIV services into primary care services was associated with significant increases in patient satisfaction in certain domains, with no negative effect on satisfaction

Top management’s snooping: Is sneaking over employees’ productivity and job commitment a wise approach?

The management’s responsibility is to monitor the employee’s performance but when it becomes a desire of the management to snoop/spy the employees’ performance then this act has a direct influence on the employees and their motivations. The paper investigates the effects of top management’s spying/snooping in the organization on employees’ productivity and job commitment. For the purpose a sample of 3500 employees via self-administered survey technique were analyzed. Tobit Model (Censored regression) has been used to interrogate the effect of snooping/ spying on employee productivity and commitment. Tobit Model marked findings that the approach of top management to snoop/spy on the employees’ productivity and job commitment affects adversely on the employees. Policy makers should adopt informal ways to practice snooping as it causes stress, mental illness, de-motivation and especially when snooping is via other co-workers and employees, it creates major disruption and a rise to politicking in organization, which effect the proper streamlining of business operations across the departments.Organizational spying/snooping, job commitment, employees’ productivity, stress

The impact of the general data protection regulation on the financial services’ industry of small European states

This paper is based on the unpublished Thesis by Magri, A. (2018). An Evaluation of the Impact of GDPR on the Local Financial Services Industry. Banking and Finance, Department of Banking and Finance, Faculty of Economics, Management and Accountancy, University of Malta, supervised by Dr. Simon GrimaPurpose: With this paper we evaluate the impact and implications of the European Union (EU) General Data Protection Regulation (GDPR) on the Financial Services Industry in small European States; specifically Malta, Slovenia, Luxembourg, Lithuania, Latvia, Estonia and Cyprus. That is, countries within the EU having less than 3 million population. Design/methodology/approach: We collected our primary data by carrying out scheduled semi-structured interviews (using WhatsApp®, Messenger® and Skype®) with 63 participants who are working directly or indirectly with GDPR in financial services between November 2018 and April 2019. The interview was structured using two impact themes, ‘Trust, Standardisation and Reputation’ and ‘Training and ‘Resources’, with 18 statements under each theme to which participants were required to answer using a 5-point Likert-scale ranging from “Strongly Disagree” to “Strongly Agree”. To answer the research questions, the empirical data collected was subjected to statistical analysis using SPSS (Version 21) namely descriptive statistics and box plots and later MANOVA, while the qualitative data was analysed using the thematic approach. Findings: We found that overall, participants feel that although GDPR has increased the work load and costs, it has helped to improve the trust, standardisation and reputation of the institutions they represent. However, this comes with some repercussions from the data subjects who are not conversant with the regulation and are apprehensive by the consents required. Originality/value: Although, all States might be represented in the decision process, the larger States usually take over and sometimes dictate the final decision. The concept of proportionality in regulations is not clean and is not effectively managed, at the disadvantage of the smaller States. Therefore, this paper is important since it voices the cries of smaller States and allows for an understanding of the impact and implications of new regulations to smaller jurisdictions, in this case within the EU.peer-reviewe
