Raised temperatures over the Kericho tea estates: revisiting the climate in the East African highlands malaria debate
Judith A Omumbo, Bradfield Lyon, Samuel M Waweru, Stephen J Connor, Madeleine C Thomson
Malaria Journal , 2011, DOI: 10.1186/1475-2875-10-12
Abstract: Over 30 years (1 January 1979 to 31 December 2009) of quality controlled daily observations ( > 97% complete) of maximum, minimum and mean temperature were used in the analysis of trends at Kericho meteorological station, sited in a tea growing area of Kenya's western highlands. Inhomogeneities in all the time series were identified and corrected. Linear trends were identified via a least-squares regression analysis with statistical significance assessed using a two-tailed t-test. These 'gold standard' meteorological observations were compared with spatially interpolated temperature datasets that have been developed for regional or global applications. The relationship of local climate processes with larger climate variations, including tropical sea surface temperatures (SST), and El Ni?o-Southern Oscillation (ENSO) was also assessed.An upward trend of ≈0.2°C/decade was observed in all three temperature variables (P < 0.01). Mean temperature variations in Kericho were associated with large-scale climate variations including tropical SST (r = 0.50; p < 0.01). Local rainfall was found to have inverse effects on minimum and maximum temperature. Three versions of a spatially interpolated temperature data set showed markedly different trends when compared with each other and with the Kericho station observations.This study presents evidence of a warming trend in observed maximum, minimum and mean temperatures at Kericho during the period 1979 to 2009 using gold standard meteorological observations. Although local factors may be contributing to these trends, the findings are consistent with variability and trends that have occurred in correlated global climate processes. Climate should therefore not be dismissed as a potential driver of observed increases in malaria seen in the region during recent decades, however its relative importance compared to other factors needs further elaboration. Climate services, pertinent to the achievement of development targets such as the
Mental Illness and the Conciousness of Freedom: The Phenomenology of Psychiatric Labelling
Bruce Bradfield
Indo-Pacific Journal of Phenomenology , 2002,
Abstract: Paradigmatically led by existential phenomenological premises, as formulated by Jean-Paul Sartre and Edmund Husserl specifically, this paper aims at a deconstruction of the value of psychiatric labelling in terms of the implications of such labelling for the labelled individual’s experience of freedom as a conscious imperative. This work has as its intention the destabilisation of labelling as a stubborn and inexorable mechanism for social propriety and regularity, which in its unyielding classificatory brandings is Indo-Pacific Journal of Phenomenology, Volume 2, Edition 1, April 2002
Examining the Lived World: The Place of Phenomenology in Psychiatry and Clinical Psychology
Bruce Bradfield
Indo-Pacific Journal of Phenomenology , 2007,
Abstract: This paper aims to explore the validity of phenomenology in the psychiatric setting. The phenomenological method - as a mode of research, a method of engagement between self and other, and a framework for approaching what it means to know - has found a legitimate home in therapeutic practice. Over the last century, phenomenology, as a philosophical endeavour and research method, has influenced a wide range of disciplines, including psychiatry. Phenomenology has enabled an enrichment of such practice through deepening the way in which we can come to know the experiences of the other. This knowing-of-the-other is explored here within the context of psychiatric and clinica assessment. The question asked is: How best can we come to know those we work with? What method of engagement can be used to most completely come to understand and narrate the experiences of the individual, and how can this be applied in the context of an assessment aimed at psychiatric or psychological intervention? Elements of phenomenological praxis are presented as definitive of the most integral way of approaching the human subject. Husserlian and Heideggerian notions are explicated and related to phenomenological conceptions of intersubjectivity, in an effort to describe a phenomenology that can be used effectively within the psychiatric setting.

Dark Matter: The Source of Space and Time  [PDF]
Keith G. Lyon
Journal of Modern Physics (JMP) , 2016, DOI: 10.4236/jmp.2016.79084
Abstract: A simple assumption for dark matter leads to magnetic-monopole-like terms to Maxwell’s Equations, a photon model with wave-particle duality, nuclear stability, a decelerating expansion of the universe, and a dark-matter relativity that defines the origin of space and time.
Magnetic Charge Theory—The Unification of Gravity with Electricity and Magnetism  [PDF]
Keith G. Lyon
Journal of Modern Physics (JMP) , 2018, DOI: 10.4236/jmp.2018.97083
Abstract: The concept of magnetic charge is further developed. The fundamental equations relating magnetic charge and magnetic fields are defined. A better photon model is developed. The ground state vibrations of particles are investigated and indicate that longitudinal waves in the ether are responsible for gravity while vortex waves can explain the Coulomb interaction. Finally, Einstein’s equation for rest mass energy is derived using electromagnetic theory. A laboratory experiment is proposed to validate the theory.
Therapeutic hypothermia post out-of-hospital cardiac arrest - more questions than answers?
Richard Lyon
Critical Care , 2011, DOI: 10.1186/cc10123
Abstract: Patients post out-of-hospital cardiac arrest (OHCA) are common admissions to the ICU. Therapeutic hypothermia has been shown to improve both survival and neurological outcome for OHCA patients surviving to reach the ICU and now forms part of routine post-resuscitation care. The Time to Target Temperature (TTTT) study group presents key observations on the relationship between body temperature and outcome following OHCA [1], yet ultimately are we left with more questions than answers on therapeutic hypothermia?Nearly a decade ago two landmark papers fundamentally changed the practice of post-resuscitation care. The Hypothermia after Cardiac Arrest study group [2] and Bernard and colleagues [3] not only demonstrated the benefit of cooling OHCA patients but also highlighted how hugely effective the therapy was, with a number needed to treat of seven patients and six patients, respectively, for survival. Such impressive therapeutic benefit is rarely seen in medical practice, let alone in critical care medicine. A key difference between these two studies was the time from return of spontaneous circulation (ROSC) to the onset of cooling. The time to reach the target temperature (<34°C) varied greatly from immediately post ROSC to over 16 hours post ROSC and yet the therapeutic benefit of cooling was still evident. The TTTT group demonstrated that the change in body temperature during the period from ROSC to cooling initiation has a direct relationship on survival [1].Since 2002 few studies have examined the optimum method, rate of cooling and timing of initiation. Little is known about the mechanism of action of therapeutic hypothermia. Whilst animal evidence strongly suggests that early cooling, especially intra-arrest, is beneficial, few human studies have demonstrated a benefit from early cooling. Early cooling, in the prehospital or emergency department setting, has significant technical challenges and may distract from the basic principles of resuscitation. Yet emerg
The variation of floods in the middle reaches of the Yangtze River and its teleconnection with El Ni o events
B. Lyon
Advances in Geosciences (ADGEO) , 2006,
Abstract: It has been well established that drought frequently emerges in several tropical regions following the onset of El Ni o. An important characteristic of such droughts is their spatial extent, which has recently been linked to the strength of a particular El Ni o event. Here the robustness of this relationship is examined through comparison of results from several gridded precipitation analyses for the global tropics. It is found that there is very good agreement across these datasets, including those which incorporate satellite rainfall estimates, confirming that maximum drought extent in tropical land areas increases nearly linearly with associated maximum sea surface temperature anomalies in the east-central tropical Pacific during El Ni o events.
