Attitude counts: engaging with rice farmers in West Africa

An international project called PADS promoted participatory learning and action research with inland valley rainfed rice farmers in West Africa. All countries received the same training, similar funding, and the same leadership. Although the staff in Ghana were conscientious and gave much training to the farmer beneficiaries, the Mali staff explicitly encouraged farmers to experiment. Farmers in Mali responded to this favourable attitude by experimenting more than those in Ghana, and in qualitatively more interesting ways. Long-term engagement with grassroots organisations may be as conducive to changing public servants' attitudes as the actual participatory approach promoted on the ground.

L'attitude compte: travail avec des riziculteurs en Afrique de l'Ouest

Un projet international appelé PADS a favorisé l'apprentissage participatif et la recherche-action avec des riziculteurs pratiquant la culture pluviale dans les vallées de l'intérieur des terres en Afrique de l'Ouest. Tous les pays ont reçu la même formation, un financement similaire et le même leadership. Alors que les membres du personnel du Ghana étaient consciencieux et dispensaient une formation considérable aux agriculteurs bénéficiaires, le personnel du Mali encourageait expressément les riziculteurs à faire des expériences. Les riziculteurs du mali ont réagi à cette attitude favorable en faisant plus d'expériences que ceux du Ghana, et ce de manières plus intéressantes sur le plan qualitatif. L'engagement à long terme avec les organisations de la base populaire peut être tout aussi propice à la modification des attitudes des fonctionnaires que l'approche participative même promue sur le terrain.

As atitudes contam: Engajamento com produtores de arroz na África Ocidental

Um projeto internacional chamado PADS promoveu uma pesquisa sobre aprendizado e ação participativa com produtores de arroz irrigado com água da chuva no interior do vale na África Ocidental. Todos os países receberam o mesmo treinamento, financiamento semelhante e a mesma liderança. Embora os funcionários de Gana estivessem cientes e oferecessem bastante treinamento aos produtores beneficiários, os funcionários de Mali incentivaram explicitamente os produtores a experimentar. Os produtores de Mali responderam a esta atitude favorável experimentando mais do que aqueles de Gana e de maneiras mais interessantes em termos qualitativos. O engajamento de longo prazo com organizações de base pode contribuir para mudar as atitudes dos servidores públicos tanto quanto a abordagem participativa real promovida na base.

La actitud cuenta: el trato personal con campesinos arroceros de África Occidental

Un proyecto internacional llamado PADS promovió el aprendizaje participativo y la investigación-acción entre campesinos que cultivaban arroz de secano en los valles centrales de África Occidental. Todos los países participantes recibieron la misma capacitación, un financiamiento similar y las mismas orientaciones. Si bien el personal de Ghana era muy diligente y transmitió muchos conocimientos a los campesinos beneficiarios en capacitaciones, el personal de Malí se centró más explícitamente en animarlos para que experimentaran. Los campesinos de Malí respondieron a esta actitud estimuladora realizando más experimentos y de maneras cualitativamente más interesantes que los campesinos de Ghana. El compromiso de largo plazo con organizaciones de base puede ser tan importante para lograr un cambio en la actitud del servidor público como el método participativo que se promueve en la actualidad sobre el terreno.     

An evaluation of non-metric cranial traits used to estimate ancestry in a South African sample

Establishing ancestry from a skeleton for forensic purposes has been shown to be difficult. The purpose of this paper is to address the application of thirteen non-metric traits to estimate ancestry in three South African groups, namely White, Black and "Coloured". In doing so, the frequency distribution of thirteen non-metric traits among South Africans are presented; the relationship of these non-metric traits with ancestry, sex, age at death are evaluated; and Kappa statistics are utilized to assess the inter and intra-rater reliability. Crania of 520 known individuals were obtained from four skeletal samples in South Africa: the Pretoria Bone Collection, the Raymond A. Dart Collection, the Kirsten Collection and the Student Bone Collection from the University of the Free State. Average age at death was 51, with an age range between 18 and 90. Thirteen commonly used non-metric traits from the face and jaw were scored; definition and illustrations were taken from Hefner, Bass and Hauser and De Stephano. Frequency distributions, ordinal regression and Cohen's Kappa statistics were performed as a means to assess population variation and repeatability. Frequency distributions were highly variable among South Africans. Twelve of the 13 variables had a statistically significant relationship with ancestry. Sex significantly affected only one variable, inter-orbital breadth, and age at death affected two (anterior nasal spine and alveolar prognathism). The interaction of ancestry and sex independently affected three variables (nasal bone contour, nasal breadth, and interorbital breadth). Seven traits had moderate to excellent repeatability, while poor scoring consistency was noted for six variables. Difficulties in repeating several of the trait scores may require either a need for refinement of the definitions, or these character states may not adequately describe the observable morphology in the population. The application of the traditional experience-based approach for estimating ancestry in forensic case work is problematic.     

ARPA-E and DARPA: Applying the DARPA model to energy innovation

ARPA-E offers a new innovation institutional model to meet energy technology challenges. Because it is explicitly based on DARPA, this article reviews the noted DARPA approach in detail. Briefly citing well-known features of DARPA, it explores a number of important features that have not been well discussed in the policy literature on DARPA. These include DARPA??s ability to undertake multigenerational technology thrusts, the synergies it has been able to create through complementary strategic technologies, its ability to build an advocate community, and connections it has built to larger innovation elements downstream from DARPA. It has also taken on incumbent technologies within both DOD and in the private sector, used ties to DOD leadership to press its advances, and supported initial market creation. The article then reviews the new ARPA-E model in detail, commenting first on how ARPA-E has adopted key DARPA approaches. It then discusses new features ARPA-E is adopting, driven by the unique demands of the complex, established energy sector. These include new ways: (1) to sharpen the research visioning, selection and support processes, (2) to build a community of support, important to its political survival, and (3) to implement technologies it supports. In addition, the further DARPA features enumerated above provide potentially useful future guideposts to ARPA-E. The paper closes with a discussion of the difficult technology implementation problems on the ??back end?? of the innovation system??including demonstrations, test beds, and initial markets. The article posits that both agencies must further address these implementation issues by fostering additional downstream partnerships, including between government and private sector.     

Parametric Insurance: Using Objective Measures to Address the Impacts of Natural Disasters and Climate Change

Parametric insurance is a promising alternative to traditional insurance when it comes to addressing catastrophic weather events and their impact on developing nations. Where available, traditional insurance is expensive and can involve protracted claim adjustment. Parametric insurance, on the other hand, provides coverage monies automatically upon the existence of certain objective weather-related parameters based upon a set formula. This model has been shown to work in the Caribbean Basin, but requires international cooperation in pooling, measuring, and managing risk. The immediate availability of emergency-response funds can be crucial in mitigating the impacts of climate change and related severe weather events.     

Validation of Ultrastructural Analysis of Mitochondrial Deposits in Cardiomyocytes as a Method of Detecting Early Acute Myocardial Infarction in Humans*

Abstract: In the present study, ultrastructural analysis of mitochondrial deposits (black dots within mitochondria) as a method for the detection of early acute myocardial infarction (AMI) was evaluated. In 24 patients with AMI and six controls, analysis was performed in the heart of infarcted patients and noninfarcted controls. In the infarction area in lactate dehydrogenase (LDH)‐diagnosed AMI, the percentage of positive mitochondria was significantly higher compared to corresponding heart tissue in control patients and compared to noninfarcted areas within these patients. Also in patients with a clinically diagnosed AMI but no LDH decoloration, a significant higher percentage of positive mitochondria was found in the left ventricle compared to controls and noninfarcted areas. In patients with AMI, an increase in mitochondria with deposits was found in the infarction area compared to controls and noninfarcted tissue within the same patient, suggesting that electron microscopical changes in mitochondria can be used for the diagnosis of AMI less than 3 h old.     

Root Morphology and Anatomical Patterns in Forensic Dental Identification: A Comparison of Computer‐Aided Identification with Traditional Forensic Dental Identification*

Abstract: An online forensic dental identification exercise was conducted involving 24 antemortem–postmortem (AM–PM) dental radiograph pairs from actual forensic identification cases. Images had been digitally cropped to remove coronal tooth structure and dental restorations. Volunteer forensic odontologists were passively recruited to compare the AM–PM dental radiographs online and conclude identification status using the guidelines for identification from the American Board of Forensic Odontology. The mean accuracy rate for identification was 86.0% (standard deviation 9.2%). The same radiograph pairs were compared using a digital imaging software algorithm, which generated a normalized coefficient of similarity for each pair. Twenty of the radiograph pairs generated a mean accuracy of 85.0%. Four of the pairs could not be used to generate a coefficient of similarity. Receiver operator curve and area under the curve statistical analysis confirmed good discrimination abilities of both methods (online exercise = 0.978; UT‐ID index = 0.923) and Spearman’s rank correlation coefficient analysis (0.683) indicated good correlation between the results of both methods. Computer‐aided dental identification allows for an objective comparison of AM–PM radiographs and can be a useful tool to support a forensic dental identification conclusion.     

When does the Apple Fall from the Tree? Static Versus Dynamic Theories Predicting Intergenerational Transmission of Convictions

Criminal behavior of parents substantially affects the criminal behavior of children. Little is known, however, about how crime is transmitted from one generation to the next. In order to test two possible explanations against each other, we pose the question whether the timing of the criminal acts of fathers is important for children’s chances of committing crime. Static theories predict that it is the number of delinquent acts performed by fathers that is important, and that the particular timing does not affect the child’s chance of committing crime. Dynamic theories state that the timing is important, and children have a greater chance of committing crime in the period after fathers have committed delinquent acts. Results show that the total number of convictions of a father is indeed very important, but also the exact timing is key to understanding intergenerational transmission of crime. In the year a father is convicted the chance his child is also convicted increases substantially and it decays in subsequent years. This decay takes longer the more crimes father has committed. Our results show that some of the assumptions of the static theories at least need to be adjusted.     

An Integrated Model of Legal and Moral Reasoning and Rule-Violating Behavior: The Role of Legal Attitudes

Legal socialization theory predicts that attitudes mediate the relation between legal reasoning and rule-violating behavior [Cohn, E. S., & White, S. O. (1990). Legal Socialization: A Study of Norms and Rules. New York: Springer-Verlag]. Moral development theory predicts that moral reasoning predicts rule-violating behavior directly as well as indirectly [Blasi, A. (1980). Bridging moral cognition and moral action: A critical review of the literature. Psychological Bulletin, 88, 1–45]. We present and test an integrated model of rule-violating behavior drawing on both theories in a longitudinal study of middle school and high school students. Students completed questionnaires three times during the course of 1 year at 6-month intervals. Legal and moral reasoning, legal attitudes, and rule-violating behavior were measured at times one, two, and three respectively. Structural equation models revealed that while moral and legal reasoning were directly and indirectly related to rule-violating behavior among high school students, legal reasoning bore no direct relation to rule-violating behavior among middle school students. The implications for an integrated model of reasoning and rule-violating behavior are discussed.     

The introduction of forensic advisors in Belgium and their role in the criminal justice system

Forensic advisors (FA) at the National Institute for Criminalistics and Criminology (NICC), generalists in forensic science, act as an advising body to the magistrate to improve communication between the various parties involved in the investigation: magistrate, police and crime scene investigators, and forensic experts. Their role is manifold, but their main objectives are to optimise trace processing by selecting the most pertinent traces in the context of the case and by advising magistrates on the feasibility of forensic analyses in particular circumstances in regards to the latest technical advances.Despite the absence of a legal framework governing their role and involvement in judicial cases, the demand for their services has increased over the years. Initially, forensic advisors were called for complex homicide cases. Due to the proximity with the Public Prosecutor's Office, the types of offences for which their expertise was sought have become more diverse (mainly including robbery, burglary and sexual assault cases), leading to a diversity in the types of cases handled by the forensic advisors (complex, simple and review).In many of the cases they are requested for, in addition to consulting on the best analytical strategy, forensic advisors also assume the role of case coordinator regarding the seized objects and their respective analyses. Indeed, in the majority of cases treated by the FAs, two or more types of expertise have been requested and performed, either at the internal laboratories of NICC or at external laboratories.This paper explains the role of the forensic advisors in Belgium, the path that let to their current status and problems encountered.
