In many respects, A History of Intelligence and Intellectual 'Disability' is a confronting work. At a literal level, it comprises eighteen chapters verging on a total of quarter of a million words, apart from twenty-two pages of primary and secondary sources. Many of its chapters are drawn from Chris Goodey's articles since the early 'nineties in such journals as Ancient Philosophy, Archiv für Geschichte der Philosophie, History of the Human Sciences, and Political Theory. However, he immediately warns us that such articles exist as a "more primitive form" (vii) of the current volume.

This paper draws upon the methodological aspect of my thesis project completed in June 2007. At the center of the research problem was the question: How do history teacher educators (HTEs) in Bahir Dar University comprehend the sources and nature of historical knowledge? Phenomenological approach to research was employed in an attempt to explicate invariant structures of their epistemic assumptions of history as a school subject. Accordingly, with six purposefully selected educators as research participants, in the two-month time field work, in- depth interview and essay questions for personal text were used to gather qualitative data. Then, the data were analyzed thematically using an adapted six-phase model and interpretive themes emerged as findings of the study. And it was learnt that the educators have a very muddled conception and unquestioned assumptions on the nature and sources of historical knowledge. With this, also phenomenological enquiry, with difficulties and rewards of its own, was found to be an appropriate strategy to understand personal meaning and beliefs of the educator with regard to disciplinary knowledge of history. The paper, therefore, describes the way I employed phenomenological research approach to understand the case, and presents my personal experience of it as a beginner education researcher.

One of the challenges for health reform in Asia is the diverse set of socio-economic and political structures, and the related variability in the direction and pace of health systems and policy reform. This paper aims to make comparative observations and analysis of health policy reform in the context of historical change, and considers the implications of these findings for the practice of health policy analysis. We adopt an ecological model for analysis of policy development, whereby health systems are considered as dynamic social constructs shaped by changing political and social conditions. Utilizing historical, social scientific and health literature, timelines of health and history for five countries (Cambodia, Myanmar, Mongolia, North Korea and Timor Leste) are mapped over a 30-50 year period. The case studies compare and contrast key turning points in political and health policy history, and examines the manner in which these turning points sets the scene for the acting out of longer term health policy formation, particularly with regard to the managerial domains of health policy making. Findings illustrate that the direction of health policy reform is shaped by the character of political reform, with countries in the region being at variable stages of transition from monolithic and centralized administrations, towards more complex management arrangements characterized by a diversity of health providers, constituency interest and financing sources. The pace of reform is driven by a country's institutional capability to withstand and manage transition shocks of post conflict rehabilitation and emergence of liberal economic reforms in an altered governance context. These findings demonstrate that health policy analysis needs to be informed by a deeper understanding and questioning of the historical trajectory and political stance that sets the stage for the acting out of health policy formation, in order that health systems function optimally along their own historical pathways.

BACKGROUND: Aloe vera supports a substantial global trade yet its wild origins, and explanations for its popularity over 500 related Aloe species in one of the world's largest succulent groups, have remained uncertain. We developed an explicit phylogenetic framework to explore links between the rich traditions of medicinal use and leaf succulence in aloes. RESULTS: The phylogenetic hypothesis clarifies the origins of Aloe vera to the Arabian Peninsula at the northernmost limits of the range for aloes. The genus Aloe originated in southern Africa ~16 million years ago and underwent two major radiations driven by different speciation processes, giving rise to the extraordinary diversity known today. Large, succulent leaves typical of medicinal aloes arose during the most recent diversification ~10 million years ago and are strongly correlated to the phylogeny and to the likelihood of a species being used for medicine. A significant, albeit weak, phylogenetic signal is evident in the medicinal uses of aloes, suggesting that the properties for which they are valued do not occur randomly across the branches of the phylogenetic tree. CONCLUSIONS: Phylogenetic investigation of plant use and leaf succulence among aloes has yielded new explanations for the extraordinary market dominance of Aloe vera. The industry preference for Aloe vera appears to be due to its proximity to important historic trade routes, and early introduction to trade and cultivation. Well-developed succulent leaf mesophyll tissue, an adaptive feature that likely contributed to the ecological success of the genus Aloe, is the main predictor for medicinal use among Aloe species, whereas evolutionary loss of succulence tends to be associated with losses of medicinal use. Phylogenetic analyses of plant use offer potential to understand patterns in the value of global plant diversity.

From far-flung sites in Australia and the Pacific Islands, Lorimer Fison and A. W. Howitt produced the landmark study Kamilaroi and Kurnai (1880). Their book revealed the complexity of Aboriginal and Pacific Island societies and changed the course of anthropology in the early years of the discipline. Using archival sources and an innovative approach, Southern Anthropology explores the research, writing and reception of Kamilaroi and Kurnai. Historical chapters track Fison and Howitt's collection and analysis of anthropological material in the context of raging debates about the evolution of humans. This narrative is interspersed with an introduction to the kinship and social organisation of Aboriginal and Pacific Island people that highlight the enduring value of Fison and Howitt's methods and the resurgence of their questions in contemporary anthropology. Southern Anthropology is designed to be read across disciplinary boundaries.

BACKGROUND: Although physical illnesses, routinely documented in electronic medical records (EMR), have been found to be a contributing factor to suicides, no automated systems use this information to predict suicide risk.

OBJECTIVE: The aim of this study is to quantify the impact of physical illnesses on suicide risk, and develop a predictive model that captures this relationship using EMR data.

METHODS: We used history of physical illnesses (except chapter V: Mental and behavioral disorders) from EMR data over different time-periods to build a lookup table that contains the probability of suicide risk for each chapter of the International Statistical Classification of Diseases and Related Health Problems, 10th Revision (ICD-10) codes. The lookup table was then used to predict the probability of suicide risk for any new assessment. Based on the different lengths of history of physical illnesses, we developed six different models to predict suicide risk. We tested the performance of developed models to predict 90-day risk using historical data over differing time-periods ranging from 3 to 48 months. A total of 16,858 assessments from 7399 mental health patients with at least one risk assessment was used for the validation of the developed model. The performance was measured using area under the receiver operating characteristic curve (AUC).

RESULTS: The best predictive results were derived (AUC=0.71) using combined data across all time-periods, which significantly outperformed the clinical baseline derived from routine risk assessment (AUC=0.56). The proposed approach thus shows potential to be incorporated in the broader risk assessment processes used by clinicians.

CONCLUSIONS: This study provides a novel approach to exploit the history of physical illnesses extracted from EMR (ICD-10 codes without chapter V-mental and behavioral disorders) to predict suicide risk, and this model outperforms existing clinical assessments of suicide risk.
