International Remittances and Private Schooling: Evidence from Kerala,India

This study investigates the impact of international remittances on private school enrolment in Kerala. Using data from the 2010 Kerala Migration Survey and employing an instrumental variable (IV‐Probit) approach to address the endogeneity of migration, we found that remittances have a positive and significant effect on private school enrolment. After disaggregating the sample into different heterogeneous groups, we found that remittances have greater effect on boys, children residing in rural areas, and those belonging to socially advantageous groups and from higher wealth quintile. Children from lower wealth quintile and belonging to socially disadvantageous groups are least affected by migration and remittances.     

On UMVU estimators and Bhattacharya bounds in exponential distributions

A subfamily of exponential distributions is considered and it is shown that the variance of the UMVU estimator of an estimable function g(θ) having power series expansion is the limit of Bhattacharya bounds.     

RESERVE PRICE EFFECTS IN AUCTIONS: ESTIMATES FROM MULTIPLE REGRESSION‐DISCONTINUITY DESIGNS

We present evidence from 260,000 online auctions of second‐hand cars to identify the impact of public reserve prices on auction outcomes. We exploit multiple discontinuities in the relationship between reserve prices and vehicle characteristics to present causal regression‐discontinuity estimates of reserve price impacts. We find an increase in reserve price decreases the number of bidders, increases the likelihood the object remains unsold, and increases expected revenue conditional on sale. We then combine these estimates to calibrate the reserve price effect on the auctioneer's ex ante expected revenue. This reveals the auctioneer's reserve price policy to be locally optimal.

Wald's approximations to the average run length in cusum procedures

Wald's approximation to the ARL(average run length in cusum) (cumulative sum) procedures are given for an exponential family of densities. From these approximations it is shown that Page's (1954) cusum procedure is (in a sense) identical with a cusum procedure defined in terms of likelihood ratios. Moreover, these approximations are improved by estimating the excess over the boundary and their closeness is examined by numerical comparisons with some exact results. Some examples are also given.     

Religious Education at Crossroads in the United Kingdom: Muslim Responses to Registration,Regulation and Inspection

Madrasah education is the bedrock of Muslim communities the world over. They are established, in essence, for the religious, spiritual, moral and social development of Muslim children. Recently, the Department for Education in the UK issued a call for evidence for requiring certain out-of-school settings to be registered, regulated and inspected. Responses to this proposal have been varied, some welcoming it whilst others expressed serious concerns. This paper explores the trends in the responses made to these proposals by three Muslim organisations. It begins by providing a nuanced understanding of the terms maktab and madrasah and shows that the call is not a new one at all. Thereafter, the worry of many politicians, educators and faith groups are considered. The findings reveal that Muslim organisations support and welcome measures to strengthen the safeguarding and well-being of children. However, a summative analysis of their responses reveals that they have serious concerns about many aspects of the proposal and the context within which it has been conceived.     

Portrayal of Muslims Following the Murders of Lee Rigby in Woolwich and Mohammed Saleem in Birmingham: A Content Analysis of UK Newspapers

In 2013, Michael Adebolajo and Michael Adebowale murdered a British soldier, named Lee Rigby in Woolwich, south-east London. In the aftermath of the incident, evidence showed Muslims had become targets for a rise in anti-Muslim hate crimes.¹1. ACPO, “True Vision Records”, 2013. Available at: http://www.reportit.org.uk/true_vision_records_a_significant_weekly_reduct (accessed 2 September 2014).View all notes Most notably, mosques had been reported to have been burnt down and graffiti with messages of hate scrawled against the walls. In such times, the role of the media is crucial in projecting a balanced approach. This study analysed newspaper coverage three weeks from the Woolwich attacks and examined the language and headlines used to describe Muslims. Over 1022 articles from UK newspapers were reviewed using the Nexis database utilising both quantitative and qualitative methods to examine the media narrative regarding Muslims and also make a comparative analysis of how the media reported on the case of Mohammed Saleem who was murdered by the far right extremist, Pavlo Lapshyn. The newspaper articles were analysed by using the computer software NVivo to search for and identify patterns across the articles in order to give an idea of the most frequent ways that Muslims were being portrayed. This paper found that news coverage had generalised about Muslims which was made in an overtly prejudicial way.     

Social Connections and Incentives in the Workplace: Evidence From Personnel Data

We present evidence on the effect of social connections between workers and managers on productivity in the workplace. To evaluate whether the existence of social connections is beneficial to the firm's overall performance, we explore how the effects of social connections vary with the strength of managerial incentives and worker's ability. To do so, we combine panel data on individual worker's productivity from personnel records with a natural field experiment in which we engineered an exogenous change in managerial incentives, from fixed wages to bonuses based on the average productivity of the workers managed. We find that when managers are paid fixed wages, they favor workers to whom they are socially connected irrespective of the worker's ability, but when they are paid performance bonuses, they target their effort toward high ability workers irrespective of whether they are socially connected to them or not. Although social connections increase the performance of connected workers, we find that favoring connected workers is detrimental for the firm's overall performance.     

Negotiation of identity and internal contradictions: the Terengganu and Kelantan Peranakan Chinese foodways compared

This study explores the Terengganu and Kelantan Peranakan Chinese foodways with special reference to two types of foods: daily and ancestral prayer foods. The principal focus is to illustrate the negotiation of identity through foodways as well as internal contradictions arising from this process of identity negotiation. These two groups of Peranakan Chinese are largely the product of acculturation by the local Malays through socio-cultural interactions, though the Kelantan Peranakan Chinese are also acculturated by the local Thai community. Their daily and ancestral prayer foods display contrasting identities that stem from the negotiating of their acculturated and primordial identities. The former displays a strong local cultural influence, while the latter displays a strong Chinese cultural influence. However, despite the pervasive influence of localisation in their daily foods, elements of hybridisation are visible in some occasionally prepared food items. Meanwhile, localised and hybrid food items are included in their ancestral prayer foods, which are supposed to express their primordial Chinese identity. These internal contractions illustrate the complexity of the negotiation of identity through foodways within a cross-cultural context.     

Foreign Remittances and Regional Poverty: Evidence from Household Data

This study examines the association between foreign remittances and poverty (incidence and severity) in the Punjab province of Pakistan. Logit regression is used to deal with binary headcount ratio, while the instrumental variable approach is employed to avoid possible endogeneity. Household-based data, covering more than 40,000 household units in Punjab, are used for the empirical estimations. After controlling for several variables, such as the number of dependents of households, age, gender, and education of the household head, the results indicate that foreign remittances’ inflow reduces the incidence and severity of poverty in all three regions of the Punjab province, North Punjab, South Punjab and Central Punjab. The South Punjab, however, is found to be poorer based on headcount poverty and severity of poverty as compared to the other two regions.     

Shifting strategy for geometric graphs without?geometry

We give a simple framework which is an alternative to the celebrated and widely used shifting strategy of Hochbaum and Maass (J. ACM 32(1):103?C136, 1985) which has yielded efficient algorithms with good approximation bounds for numerous optimization problems in low-dimensional Euclidean space. Our framework does not require the input graph/metric to have a geometric realization??it only requires that the input graph satisfy some weak property referred to as growth boundedness. Growth bounded graphs form an important graph class that has been used to model wireless networks. We show how to apply the framework to obtain a polynomial time approximation scheme (PTAS) for the maximum (weighted) independent set problem on this important graph class; the problem is W[1]-complete. Via a more sophisticated application of our framework, we show how to obtain a PTAS for the maximum (weighted) independent set for intersection graphs of (low-dimensional) fat objects that are expressed without geometry. Erlebach et al. (SIAM J. Comput. 34(6):1302?C1323, 2005) and Chan (J. Algorithms 46(2):178?C189, 2003) independently gave a PTAS for maximum weighted independent set problem for intersection graphs of fat geometric objects, say ball graphs, which required a geometric representation of the input. Our result gives a positive answer to a question of Erlebach et al. (SIAM J. Comput. 34(6):1302?C1323, 2005) who asked if a PTAS for this problem can be obtained without access to a geometric representation.
