Establishing the link between representative bureaucracy and performance: The South African case

Representative bureaucracy is a critical element of modern public administration and governance. Since the advent of nonracial democracy, the South African government has transformed the apartheid bureaucracy into a new public service that closely mirrors the country's diverse population. Questions remain, however, about how this demographic transformation has impacted the public service. Grounded in the theory of representative bureaucracy, we use a mixed methods approach to examine the relationship between representation of historically disadvantaged groups and performance of national departments in South Africa. Analyses of panel data indicate that as national departments become more representative by employing a greater percentage of Blacks, they become more effective at achieving their goals. Interviews with officials in national departments corroborate this and reveal a range of underlying pathways linking representation of historically disadvantaged groups to performance.     

Democratic engagement in the digital age: youth,social media and participatory politics in Kenya

As the communication world becomes more complex and participatory, social networking sites (SNSs) have emerged as a platform with the potential to invigorate democracy and political engagement. However, the value of SNSs in politics remains contested among researchers. The study reported on in this article was based on a survey of 600 university students, aged between18 and 35, to examine the relationship between social media use and political engagement among the youth in Kenya. The study focused on the extent to which SNSs facilitate consumption of political information and the role of SNSs in influencing political interest, knowledge and behaviour among the youth. The study found that reliance on SNSs is positively associated with political participation; however, this influence is limited, and though useful, it does not radically transform political engagement. Therefore, the capacity of SNSs to shape opinion and influence political preferences is limited but internet based political activities like posting and distributing campaign information and consumption of political content have a bearing on political participation. The study concluded that while SNSs do not seem to have a major direct impact on political choices among users, politicians and other campaign actors cannot ignore the opportunity provided by these platforms in the voter mobilisation process.     

Platforms for institutional change: assessing the potential of livelihood enhancement groups as community entry points in Zambia

To address the livelihood problems faced by the poor and vulnerable in Northern Province of Zambia, a novel collective action approach called livelihoods enhancement groups (LEGs) was used as a platform for facilitating research on development initiatives to generate change. Using focus group discussions and key informant interviews, this article assesses the potential of using the LEGs approach in generating change. The livelihood changes observed arose with the LEG as a platform through which different knowledge nodes interacted. Livelihood areas that LEGs affected included crop production, livestock production, nutrition, and access to credit.     

Pathological counterinsurgency: the failure of imposing legitimacy in El Salvador,Afghanistan, and Iraq

Many voices in the US policy community have suggested that El Salvador provided a model for US counterinsurgency operations in Iraq and Afghanistan, based on the unsound contention that elections increased government legitimacy and effectiveness. The same flawed assessments were present in counterinsurgency strategy in Iraq and Afghanistan – unfounded assumptions that elections would increase legitimacy and improve institutional performance and human rights records lead to inaccurate analysis and bad strategy. Indeed, the US experience calls into question the ability of even a great power to impose legitimacy on a partner in order to wage counterinsurgency. Assuming that elections will advance such legitimacy is a dangerous pathology.     

Evaluation of DNA Extraction Methods for Processing Fingerprint Powder-Coated Forensic Evidence

In unison, fingerprinting and DNA analysis have played a pivotal role in forensic investigations. Fingerprint powders that are available on the market can come in a range of colors and with specific properties. This study evaluated the efficiency of DNA extraction from samples coated with 3 brands of fingerprint powders: Lightning, Sirchie, and SupraNano, covering a range of colors and properties. A total of 23 fingerprint powders were tested using the Chelex, Promega DNA IQ™, and Applied Biosystems™ PrepFiler™ DNA extraction protocols. The DNA IQ™ and PrepFiler™ methods extracted higher yields of DNA in comparison to Chelex, which also accounted for better quality of PowerPlex x00AE; 21 DNA profiles recovered. There were no signs of degradation or inhibition in the quantification data, indicating that samples returning low DNA yield was due to interference during DNA extraction and not PCR inhibition. DNA profiles were recovered from the majority of fingerprint powders with only a single powder, Sirchie Magnetic Silver, failing to produce a profile using any of the methods tested. A link was observed between the DNA extraction chemistry, fingerprint powder property, that is, nonmagnetic, magnetic and aqueous, and the brand of fingerprint powder. Overall, the DNA IQ™ method was favorable for nonmagnetic fingerprint powders, while magnetic fingerprint powders produced more DNA profiles when extracted with the PrepFiler™ chemistry. This study highlights the importance of screening DNA extraction chemistries for the type of fingerprint powder used, as there is not a single DNA extraction method that suits all fingerprint powder brands and properties.     

Fentanyl Detection Using Eosin Y Paper Assays,

Eosin Y is a potential new color test for use in detecting illicit drugs that has not been extensively studied. In the present study, a variety of drugs of abuse and fentanyl analogues were tested to determine which drugs will bind to eosin Y, which functional groups are capable of binding and eliciting a color change, and a mechanism for eosin Y binding to fentanyl. Further, these agents were combined with common cutting agents and other drugs of abuse in order to determine the fentanyl detection limit in a drug mixture using an eosin Y test strip. Additionally, cobalt thiocyanate was used to determine whether the combination of cobalt thiocyanate and eosin Y has the potential to identify fentanyl. Through the testing performed, we concluded that (i) Eosin Y is capable of detecting low amounts of fentanyl down to 1%, (ii) Eosin Y binds to select tertiary amines to produce an orange to pink color change, and (iii) Eosin Y binds to the nonpiperidine ring nitrogen of fentanyl as a primary binding site and the piperidine ring nitrogen as a secondary binding site. While the cobalt thiocyanate assay detected 1% fentanyl in some of the mixtures, eosin Y detected 1% fentanyl in all mixtures. Finally, eosin Y was able to detect fentanyl in forensic case samples containing heroin and various cutting agents. Based on our results, eosin Y has the potential to screen for fentanyl and fentanyl analogues and can detect fentanyl in low amounts when mixed with common cutting agents.

“[It's] what you do after the mistake that counts”: Positive employment credentials,criminal record stigma,and potential pathways of mediation

The findings from prior research indicate that positive credentials, or documentation of prosocial accomplishments, can vary in strength and perceived value in mitigating aversions to hiring individuals with criminal records. In the current study, we examine why certain types of positive credentials may be more influential in reducing stigma than others. Using data from a nationwide survey of American adults (N = 3,476), we combine a mediation analysis with content-coding of open-ended responses to identify key themes and patterns in decision processes. The results indicate the factors examined here—employee dependability, trustworthiness, recidivism risk, and workplace crime—explain a large proportion of the total effect across credentials and are the strongest for reference letters. Trustworthiness is the most influential mediator across credentials, whereas general recidivism risk is consistently the lowest. An analysis of open-ended responses provides further context and insight into these patterns. Although policy strategies often target risk reduction on the employer's end, credentials that also relay information about skills, character, and the timeline of recent life events are especially influential.     

Forensic isoscapes based on intra-individual temporal variation of δ18O and 206Pb/207Pb in human teeth

Isotopic signatures used in the georeferencing of human remains are largely fixed by spatially distinct geologic and environmental processes. However, location-dependent temporal changes in these isotope ratios should also be considered when determining an individual’s provenance and/or trajectory. Distributions of the relevant isotopes can be impacted by predictable external factors such as climate change, delocalisation of food and water sources and changes in sources and uses of metals. Using Multi-Collector Inductively-Coupled Plasma Mass Spectrometer (MC-ICP-MS) analyses of ²⁰⁶Pb/²⁰⁷Pb in tooth enamel and dentin from a population of 21 ± 1-year-old individuals born circa 1984 and isotope ratio mass spectrometry (IRMS) of δ¹⁸O in their enamel, we examined the expected influence of some of these factors. The resulting adjustments to the geographic distribution of isotope ratios (isoscapes) found in tooth enamel and dentin may contain additional useful information for forensic identification, but the shifts in values can also impact the uncertainty and usefulness of identifications if they are not taken into account.

KEY POINTS

• Isoscapes of ²⁰⁶Pb/²⁰⁷Pb and δ¹⁸O used for geolocation are not static.
• Within a few years, the enamel and dentin of a person may exhibit measurable differences in ²⁰⁶Pb/²⁰⁷Pb even without changing locations.
• Changes in climatic patterns tied to rising temperatures are more significant than the direct effect of increasing temperature on δ¹⁸O fixed in tooth bioapatite.
• Third molar (M3) enamel mineralisation includes material incorporated from before formal amelogenesis takes place.
