Birth Registration in China: Practices,Problems and Policies

Data from interviews with staff of government offices, relevant literature and national statistics are used to analyze laws, regulations, rules, policies and operational procedures concerning birth registration in China. The current status of and existing problems with birth registration, as well as the influences of delayed birth registration on children’s rights and welfare are examined. Finally, barriers to birth registration in China are explored and strategies to improve the process of birth registration and to protect children’s rights are proposed. The main findings are as follows: First, the rate of birth registration in China is low and in rural areas and for marginalized children, it is even lower. Second, the dual birth registration system and interference from the Population and Family Planning department cause serious administrative difficulties. Third, the serious problems surrounding birth registration in China are a result of interactions among the interests of different stakeholders, while most stakeholders are unaware of the dimensions of the problems. Strategies and policies to promote birth registration are discussed.     

Identifying the time of step change in the mean of autocorrelated processes

Control charts are used to detect changes in a process. Once a change is detected, knowledge of the change point would simplify the search for and identification of the special cause. Consequently, having an estimate of the process change point following a control chart signal would be useful to process analysts. Change-point methods for the uncorrelated process have been studied extensively in the literature; however, less attention has been given to change-point methods for autocorrelated processes. Autocorrelation is common in practice and is often modeled via the class of autoregressive moving average (ARMA) models. In this article, a maximum likelihood estimator for the time of step change in the mean of covariance-stationary processes that fall within the general ARMA framework is developed. The estimator is intended to be used as an “add-on” following a signal from a phase II control chart. Considering first-order pure and mixed ARMA processes, Monte Carlo simulation is used to evaluate the performance of the proposed change-point estimator across a range of step change magnitudes following a genuine signal from a control chart. Results indicate that the estimator provides process analysts with an accurate and useful estimate of the last sample obtained from the unchanged process. Additionally, results indicate that if a change-point estimator designed for the uncorrelated process is applied to an autocorrelated process, the performance of the estimator can suffer dramatically.     

Mobile phones and core network growth in Kenya: Strengthening weak ties

In contrast to recent US studies showing a decrease in core network size, our Kenyan data reveals substantial network growth. We attribute this to the diffusion of mobile telephones. Results from pooled survey data from Nairobi professionals and entrepreneurs in 2002 and 2007 as well as qualitative interviews from 2007 to 2009 show virtual saturation in the diffusion of phones during this period, but no direct effect of technology use. What explains this puzzle is a network effect of mobile telephony: increased technological access to existing networks in a context of resource scarcity leads to a strengthening of weak ties and the enhancement of core networks among Kenyans. Video ethnographic data before and after the 2007 post-election unrest supports this interpretation, showing that mobile phones are a crucial resource in managing interpersonal networks for instrumental purposes.

On testing homogeneity of t normal means against ordered alternatives in r groups

Given k=rt normal populations with a common but unknown variance consisting of t treatments applied to r different groups of units, and supposing that in each group the means are monoto-nically non-decreasing (or non-increasing), then the likelihood ratio test of homogeneity of the means in each group against the simple order alternative is considered. Critical values are provided when one observation is drawn from each of the k populations.     

Simultaneous one-sided tolerance intervals for sets of contrasts from normal populations

This paper considers the problem of constructing simultaneous prediction and tolerance intervals for sets of contrasts of normal variables in situations where simultaneous intervals are available. Tables are given with critical values used in simultaneous tolerance bounds for two classes of contrasts: pairwise many-one and profile type.     

How do you measure trust in social institutions and health professionals? A systematic review of the literature (2012–2021)

The importance of measuring trust in health systems has been accentuated due to its correlation with important health outcomes aimed at reducing COVID-19 transmission. A systematic review published almost a decade ago identified gaps in measures including the lack of focus on trust in systems, inconsistency regarding the dimensionality of trust and need for research to strengthen the validity of measures. Given developments in our understandings of trust since its publication, we sought to identify new scales developed, existing ones adapted in response to identified gaps, and agendas for future research. Using the PRISMA approach for systematic reviews, we conducted a search in four databases. A total of 26 articles were assessed. Twelve new scales were identified, while 14 were adapted for different settings and populations. Literature continues to focus on measuring trust in health professionals rather than systems. Various shortcomings were identified, including some articles not mentioning the dimensions included in the scale and suboptimal use of validity and reliability testing and/or reporting. Moreover, a variety of terms were used for dimensions. Future research is needed to address these gaps and consequently, to understand their correlation with health behaviors and outcomes more accurately.     

A Concept Mapping Study on Social Inclusion in Hong Kong

A focus group study involving concept mapping was conducted in September 2012 to investigate how the concept of social inclusion was understood by Hong Kong residents. It was a replication of an earlier UK study. Seven groups involving 61 participants (38 females; 23 males) were interviewed, including non-professional workers at a Non-government Organisation service, senior centre users, a mixed group of community residents, people with severe mental illness, professional social service providers, communication studies students, and social work students. Data analysis using Nvivo 10 and systematic thematic analysis identified six major themes including: (1) material resources and wealth, (2) work, (3) social (dis)harmony and diversity, (4) discrimination, (5) communication, and (6) participation in activities. An overall final model of Social Inclusion for Hong Kong based on concept maps for all seven groups is presented. The results will inform the conceptualisation and development of a Chinese-language measure of social inclusion (SCOPE-C) based on translation and cultural adaption of the Social and Community Opportunities Profile (SCOPE) developed in UK.     

Social Inclusion and Health Conditions Among Chinese Immigrants in Hong Kong and the United Kingdom: An Exploratory Study

Whether and how immigrants are included in the host society has become a hot topic in the context of globalization. How inclusive a society is for immigrants can be answered by comparing the inclusion of immigrants to near-culture host society and those to a different-culture society. This paper reports the social inclusion and their correlation with health conditions among Chinese immigrants in Hong Kong and the United Kingdom. Two non-probability sample surveys were conducted using the Social and Communities Opportunities Profile and its Chinese version as survey instruments. Altogether 56 new arrivals in Hong Kong and 51 immigrants in UK were recruited through NGOs to participate in face-to-face individual interviews. Both Hong Kong and UK participants reported high overall social inclusion. The two sub-samples shared many similarities in the perceived opportunities and satisfaction of opportunities in various social domains. There was evidence that immigrants in a host society with similar language demonstrated higher perceived satisfaction with opportunities in contact with friends and family, as well as higher perceived opportunities for community involvement than immigrants in a society with a different language. However, overall social inclusion appeared to be independent of one’s health conditions.
