Symbiotic relationships: saviour siblings, family rights and biomedicine

It is now possible to combine the use of preimplantation genetic diagnosis (PGD) and tissue matching to select an IVF embryo that will, after birth, be a compatible tissue donor for an existing individual. This article analyses the ethical issues and the regulatory frameworks that intersect around the creation of tissue compatible children.     

Practice in search of a theory: The case of intensive supervision— An extension of an old practice or a new approach?

Intensive supervision of probationers and parolees has recently emerged as a potential solution to the chronic problem of overcrowding in our jails and prisons. This emergence has taken place in the absence of any true theory which supports the contention that more supervision will lead to lower recidivism rates. The future of this option is analyzed within this framework. This article represents an updated version of a paper, “Practice In Search of a Theory: The Case of Intensive Probation,” delivered at the Annual Conference, Academy of Criminal Justice Sciences, Chicago, Illinois, March, 1984. While prepared under the auspices of the National Institute of Justice, the views expressed are those of the author and do not necessarily represent the official position or policies of either the National Institute of Justice or the U.S. Department of Justice.

Discursive Emotional Appeals in Sustaining Violent Social Movements in Iraq, 2003–11

How are some rebel leaders able to sustain violent collective action but others not? Most theories focus on leaders' use of selective incentives and efforts to lower their transaction costs and raise those of the government. We argue that a leader's ability to arouse emotions of anger, humiliation, and fear is also critical. Foreign leaders and former exiles typically lack the legitimacy and understanding of local politics necessary to incite such emotions. We test this argument in three case studies in Iraq between 2003 and 2011. In this period, the Sadrist Trend sustained violent collective action and gained lasting political power, the Islamic Supreme Council of Iraq failed to maintain its influence, and al-Qaeda in Iraq first gained and then lost its ability to mobilize violence.     

Using Named Entities for Computer‐Automated Verbal Deception Detection

There is an increasing demand for automated verbal deception detection systems. We propose named entity recognition (NER; i.e., the automatic identification and extraction of information from text) to model three established theoretical principles: (i) truth tellers provide accounts that are richer in detail, (ii) contain more contextual references (specific persons, locations, and times), and (iii) deceivers tend to withhold potentially checkable information. We test whether NER captures these theoretical concepts and can automatically identify truthful versus deceptive hotel reviews. We extracted the proportion of named entities with two NER tools (spaCy and Stanford's NER) and compared the discriminative ability to a lexicon word count approach (LIWC) and a measure of sentence specificity (speciteller). Named entities discriminated truthful from deceptive hotel reviews above chance level, and outperformed the lexicon approach and sentence specificity. This investigation suggests that named entities may be a useful addition to existing automated verbal deception detection approaches.     

Labor Market Returns to MBAs From Less-Selective Universities: Evidence From a Field Experiment During COVID-19

Master's degree enrollment and debt have increased substantially in recent years, raising important questions about the labor market value of these credentials. Using a field experiment featuring 9,480 job applications submitted during the early months of the COVID-19 pandemic, I examine employers’ responses to job candidates with a Master of Business Administration (MBA), which represents one-quarter of all master's degrees in the United States. I focus on MBAs from three types of less-selective institutions that collectively enroll the vast majority of master's students: for-profit, online, and regional universities. Despite the substantial time and expense required for these degrees, job candidates with MBAs from all three types of institutions received positive responses from employers at the same rate as candidates who only had a bachelor's degree—even for positions that listed a preference for a master's degree. Additionally, applicants with names suggesting they were Black men received 30 percent fewer positive responses than otherwise equivalent applicants whose names suggested they were White men or women, providing further evidence of racial discrimination in hiring practices.
