Devising: Pioneering Uncharted Territory in Theater

Throughout theatre history, styles of theatre have come in and out of favor in response to the zeitgeist of the period. Neoclassical, Melodrama, Naturalism, all have their place in history offering enlightenment, passion and truth each in tune with the values of the culture in which it was created. As society transforms, so too does the stage, offering new ways to reflect, interpret and challenge our assumptions about the changing world. Our current society wrestles with a ‘shrinking world’, a world consumed with technological advances that fan the fire of the growing interconnectedness of human beings all over the earth. This ‘shrinking world’ phenomenon has the effect of an‘expanded world awareness’. That is to say, now more than ever we question all assumption regarding singular perspectives and cultural convictions. What our new society values is diversification of insight and a myriad of experiences from which to draw our conclusions about the world in which we live. The kind of theatre that fills this need is Devised Theatre. Theatre is a collaborative art form by nature. Theatre cannot be practiced alone. One must partner other artists as well as an audience in order to create a theatre performance. Theatre is a dialogue which can take many shapes. Devised Theatre is a process of making theatre that enables a group of performers to be physically and practically creative in the sharing and shaping of an original product that directly emanates from assembling, editing and reshaping individual’s contradictory experiences of the world. A devised theatre product is a work that has emerged from and been generated by a group of people working in collaboration. There is an emphasis on a way of working that values an accumulation of ideas. (Oddey)

Theoretical Calculations of Acid Dissociation Constants: A Review Article

Acid dissociation constants, or pKa values, are essential for understanding many fundamental reactions in chemistry. These values reveal the deprotonation state of a molecule in a particular solvent. There is great interest in using theoretical methods to calculate the pKa values for many different types of molecules. These include molecules that have not been synthesized, those for which experimental pKa determinations are difficult, and for larger molecules where the local environment changes the usual pKa values, such as for certain amino acids that are part of a larger polypeptide chain. Chemical accuracy in pKa calculations is difficult to achieve, because an error of 1.36 kcal/mol in the change of free energy for deprotonation in solvent results in an error of 1 pKa unit. In this review the most valuable methods for determining accurate pKa values in aqueous solution are presented for educators interested in explaining or using these methods for their students.

An anatomical investigation of the cervicothoracic ganglion

Anatomical variability within the autonomic nervous system has long been accepted. This study evaluated the anatomical variability of the cervicothoracic ganglion (CTG) according to its form and, in addition, provided precise measurements between the CTG and the anterior tubercle of the transverse process of the sixth cervical vertebra (C6TP), the first costovertebral articulation, and the vertebral artery. Forty-two adult cadavers were dissected, 22 male and 20 females. Five main forms of CTG were documented; spindle (31.9%), dumbbell (23.2%), truncated (21.7%), perforated (14.5%), and inverted-L (8.7%). The means for length, width, and thickness of the CTG were 18.5 mm, 8.2 mm, and 4.5 mm, respectively. The dimensions were found to be slightly larger in the males than females and on the left sides as compared to the right. The mean shortest distance between the CTGs and the vertebral artery was found to be 2.8 mm, whilst the mean shortest distances to C6TP was 25.7 mm and to the first costovertebral articulation was 1.7 mm. There is great variability in the morphology of the CTG with five common forms consistently seen. The relation to the vertebral artery may influence the form of the ganglion. Two previously undocumented forms are recorded; the truncated which describes the important juxtaposition of the CTG and the vertebral artery and the perforated which describes the piercing of the ganglion itself by the artery. The findings are considered to be of clinical importance to anesthetists, surgeons, neurosurgeons, and anatomists.

Modes of Diversification in Bulgarian Higher Education: Case Studies in four Disciplines

This project was stimulated by the unprecedented speed and scope of changes in Bulgarian higher education since 1989. The rapid growth of the student population and the emergence of a new private sector in higher education led to tightening governmental control and a growing criticism of autonomy and academic freedom. This raised questions about the need for diversification in the field, about the importance of recent innovations in terms of strategic choices for future development and so of how higher education governance could maintain diversity without the system deteriorating. The group first traced the extent of spontaneous processes of innovation at the level of content, of institutions, and the organisation of teaching and learning processes. They then identified the different parties in the struggle for institutionalisation and against diversification, and promising mechanisms for maintaining diversity in higher education. On this basis they outlined a basis for a wide-ranging public discussion of the issue which may serve as a corrective to the mechanisms of state control. Their work included analysis of the legislative framework laid down in the Higher Education Act, which effectively dispenses with the autonomy of universities. They then surveyed the views of both high-level executives in the field and the academics actually involved in the process, as well as of the "consumers" of the educational product, i.e. the students. In considering diversification, they focused on four different types of programmes, including those where diversification is largely limited to content level (e.g. Law), those where it operates mainly on structural levels (e.g. Industrial Management), those where it is often feigned (e.g. Social Work), and those where it is at best formal and sporadic (e.g. Mechanical Engineering). They conclude that the educational system in Bulgaria has considerable internal resources for development. The greatest need is for adequate statutory regulation of academic life which will provide incentives for responsible academic development of higher education institutions and create conditions for the institutionalisation of academic self-organisation and self-control, which will in turn limit the pathological trends in the diversification processes.

Early clinical trial experience with vaccine therapies in non-small-cell lung cancer

Cancer immunotherapy has made great progress because of advances in immunology and molecular biology. Increased understanding of mechanisms by which lung cancer cells escape the immune system and recognition of key tumor antigens and immune system components involved in tumor ignorance have led to the development of a variety of lung cancer vaccines. Immunotherapy has advanced from using nonspecific immunomodulatory agents to lung cancer-specific tumor antigens and tumor cell-derived vaccines. While understanding of immune processes and malignancy has improved, there is great opportunity for further research of vaccine therapies in non-small-cell lung cancer. Herein, we review the development and evolution of early lung cancer vaccine trials.

The Electroplating of Cadmium from Sulfate Solutions

It has been proven that cadmium forms a very satisfactory plate on steel, which has to withstand severe corrosion, especially the corrosion of sea water and spray. The metal is now successfully plated electrolytically from cyanide solutions, but wherever work is carried on with cyanide, there is great danger of poisoning to the workers.

[Gerodontology consultation in geriatric facilities: general health status (I)]

Dental undertreatment is often seen in the older population. This is particularly true for the elderly living in nursing homes and geriatric hospitals. The progression of chronic diseases results in loss of their independence. They rely on daily support and care due to physical or mental impairment. The visit of a dentist in private praxis becomes difficult or impossible and is a logistic problem. These elderly patients are often not aware of oral and dental problems or these are not addressed. The geriatric hospital Bern, Ziegler, has integrated dental care in the concept of physical rehabilitation of geriatric patients. A total of 139 patients received dental treatment in the years 2005/2006. Their mean age was 83 years, but the segment with > 85 years of age amounted to 46%. The general health examinations reveald multiple and complex disorders. The ASA classification (American Society of Anesthesiologists, Physical Status Classification System) was applied and resulted in 15% = P2 (mild systemic disease, no functional limitation), 47% = P3 (severe systemic disease, definite functional limitations) and 38% = P4 (severe systemic disease, constant threat to life). Eighty-seven of the patients exhibited 3 or more chronic diseases with a prevalence of cardiovascular diseases, musculoskelettal disorders and dementia. Overall the differences between men and women were small, but broncho-pulmonary dieseases were significantly more frequent in women, while men were more often diagnosed with dementia and depression. Verbal communication was limited or not possible with 60% of the patients due to cognitive impairment or aphasia after a stroke. Although the objective treatment need is high, providing dentistry for frail and geriatric patients is characterized by risks due to poor general health conditions, difficulties in communication, limitations in feasibility and lack of adequate aftercare. In order to prevent the problem of undertreatment, elderly independently living people should undergo dental treatment regularly and in time. Training of nurses and doctors of geriatric hospitals in oral hygiene should improve the awareness. A multidisciplinary assessment of geriatric patients should include the oral and dental aspect if they enter the hospital.

Comparison of phenotypes of childhood wheeze and cough in 2 independent cohorts

BACKGROUND Among children with wheeze and recurrent cough there is great variation in clinical presentation and time course of the disease. We previously distinguished 5 phenotypes of wheeze and cough in early childhood by applying latent class analysis to longitudinal data from a population-based cohort (original cohort). OBJECTIVE To validate previously identified phenotypes of childhood cough and wheeze in an independent cohort. METHODS We included 903 children reporting wheeze or recurrent cough from an independent population-based cohort (validation cohort). As in the original cohort, we used latent class analysis to identify phenotypes on the basis of symptoms of wheeze and cough at 2 time points (preschool and school age) and objective measurements of atopy, lung function, and airway responsiveness (school age). Prognostic outcomes (wheeze, bronchodilator use, cough apart from colds) 5 years later were compared across phenotypes. RESULTS When using a 5-phenotype model, the analysis distinguished 3 phenotypes of wheeze and 2 of cough as in the original cohort. Two phenotypes were closely similar in both cohorts: Atopic persistent wheeze (persistent multiple trigger wheeze and chronic cough, atopy and reduced lung function, poor prognosis) and transient viral wheeze (early-onset transient wheeze with viral triggers, favorable prognosis). The other phenotypes differed more between cohorts. These differences might be explained by differences in age at measurements. CONCLUSIONS Applying the same method to 2 different cohorts, we consistently identified 2 phenotypes of wheeze (atopic persistent wheeze, transient viral wheeze), suggesting that these represent distinct disease processes. Differences found in other phenotypes suggest that the age when features are assessed is critical and should be considered carefully when defining phenotypes.

Current practice in neuropsychological outcome reporting after aneurysmal subarachnoid haemorrhage

BACKGROUND Neuropsychological deficits (NPD) are common in patients with aneurysmal subarachnoid haemorrhage (aSAH). NPD are one of the major limiting factors for patients with an otherwise acceptable prognosis for sustained quality of life. There are only a few studies reporting outcome after aSAH, which used a standardized neuropsychological test battery as a primary or secondary outcome measure. Aim of this study was to determine the current practice of reporting NPD following aSAH in clinical studies. METHODS A MEDLINE analysis was performed using the search term "subarachnoid haemorrhage outcome". The latest 1,000 articles were screened. We recorded study design, number of patients, and the presence of neuropsychological outcome report. Additionally, the time of testing after aSAH, the neuropsychological tests administered, as well as the percentage of patients with NPD were analyzed. RESULTS A total of 324 publications between 2009 and 2012 were selected for further review. Of those, 21 studies (6.5%) reported neuropsychological outcome, in 2,001 of 346,666 patients (0.6%). The assessment of NPD differed broadly using both subjective and objective cognitive evaluation, and a large variety of tests were used. CONCLUSION Neuropsychological outcome is underreported, and there is great variety in assessment in currently published clinical articles on aSAH. Prospective randomized trials treating aSAH may benefit from implementing more comprehensive and standardized neuropsychological outcome measures. This approach might identify otherwise unnoticed treatment effects in future interventional studies of aSAH patients.

Fourier transform infrared spectroscopy, a new method for rapid determination of total organic and inorganic carbon and biogenic silica concentration in lake sediments

Abstract We demonstrate the use of Fourier transform infrared spectroscopy (FTIRS) to make quantitative measures of total organic carbon (TOC), total inorganic carbon (TIC) and biogenic silica (BSi) concentrations in sediment. FTIRS is a fast and costeffective technique and only small sediment samples are needed (0.01 g). Statistically significant models were developed using sediment samples from northern Sweden and were applied to sediment records from Sweden, northeast Siberia and Macedonia. The correlation between FTIRS-inferred values and amounts of biogeochemical constituents assessed conventionally varied between r = 0.84–0.99 for TOC, r = 0.85– 0.99 for TIC, and r = 0.68–0.94 for BSi. Because FTIR spectra contain information on a large number of both inorganic and organic components, there is great potential for FTIRS to become an important tool in paleolimnology.

Oxygen regulates molecular mechanisms of cancer progression and metastasis

Oxygen is the basic molecule which supports life and it truly is “god's gift to life.” Despite its immense importance, research on “oxygen biology” has never received the light of the day and has been limited to physiological and biochemical studies. It seems that in modern day biology, oxygen research is summarized in one word “hypoxia.” Scientists have focused on hypoxia-induced transcriptomics and molecular–cellular alterations exclusively in disease models. Interestingly, the potential of oxygen to control the basic principles of biology like homeostatic maintenance, transcription, replication, and protein folding among many others, at the molecular level, has been completely ignored. Here, we present a perspective on the crucial role played by oxygen in regulation of basic biological phenomena. Our conclusion highlights the importance of establishing novel research areas like oxygen biology, as there is great potential in this field for basic science discoveries and clinical benefits to the society.

Runaway and Throwaway Youth: Time for Policy Changes and Public Responsibility

The traditional American dream of owning a home, obtaining a college education, and working at a good, paying job is only that, a dream, for scores of homeless youth in America today. There is a growing street population of young people who have been thrown out of their homes by their caretakers or their families, and who face life-threatening situations each day. For these youth, the furthest thing in their lives is reaching the so-called “American Dream;” and their most immediate need is survival, simply living out the day in front of them. They have few options that lead to a decent and safe living environment. Their age, lack of work experience, and absence of a high school diploma make it most difficult to find a job. As a result, they turn to other means for survival; runaways and throwaways are most vulnerable to falling prey to the sex trade, selling drugs, or being lured into human trafficking, and some steal or panhandle. Street youth end up spending their nights in bus stations or finding a room in an abandoned building or an empty stairwell to sleep. Attempting to identify a specific number of homeless youth is difficult at best, but what is even more perplexing is our continued inability to effectively protect our children. We are left with a basic question framed by the fundamental tenets of justice: what is a community’s responsibility to its youth who, for whatever reason, end up living on the streets or in unsafe, abusive environments? The purpose of this paper is to briefly outline the characteristics of homeless youth, in particular differentiating between throwaways and runaways; explore the current federal response to homeless youth; and finally, address the nagging question that swirls around all children: can we aggressively aspire to be a community where every child is healthy and safe, and able to realize his or her fullest potential?

Development of a Bayesian Joint Logistic Model to Better Study the Association between Haplotypes and Disease

In 2011, there will be an estimated 1,596,670 new cancer cases and 571,950 cancer-related deaths in the US. With the ever-increasing applications of cancer genetics in epidemiology, there is great potential to identify genetic risk factors that would help identify individuals with increased genetic susceptibility to cancer, which could be used to develop interventions or targeted therapies that could hopefully reduce cancer risk and mortality. In this dissertation, I propose to develop a new statistical method to evaluate the role of haplotypes in cancer susceptibility and development. This model will be flexible enough to handle not only haplotypes of any size, but also a variety of covariates. I will then apply this method to three cancer-related data sets (Hodgkin Disease, Glioma, and Lung Cancer). I hypothesize that there is substantial improvement in the estimation of association between haplotypes and disease, with the use of a Bayesian mathematical method to infer haplotypes that uses prior information from known genetics sources. Analysis based on haplotypes using information from publically available genetic sources generally show increased odds ratios and smaller p-values in both the Hodgkin, Glioma, and Lung data sets. For instance, the Bayesian Joint Logistic Model (BJLM) inferred haplotype TC had a substantially higher estimated effect size (OR=12.16, 95% CI = 2.47-90.1 vs. 9.24, 95% CI = 1.81-47.2) and more significant p-value (0.00044 vs. 0.008) for Hodgkin Disease compared to a traditional logistic regression approach. Also, the effect sizes of haplotypes modeled with recessive genetic effects were higher (and had more significant p-values) when analyzed with the BJLM. Full genetic models with haplotype information developed with the BJLM resulted in significantly higher discriminatory power and a significantly higher Net Reclassification Index compared to those developed with haplo.stats for lung cancer. Future analysis for this work could be to incorporate the 1000 Genomes project, which offers a larger selection of SNPs can be incorporated into the information from known genetic sources as well. Other future analysis include testing non-binary outcomes, like the levels of biomarkers that are present in lung cancer (NNK), and extending this analysis to full GWAS studies.

Envisioning sustainable water futures in a transdisciplinary learning process: combining normative, explorative, and participatory scenario approaches

Competing water demands for household consumption as well as the production of food, energy, and other uses pose challenges for water supply and sustainable development in many parts of the world. Designing creative strategies and learning processes for sustainable water governance is thus of prime importance. While this need is uncontested, suitable approaches still have to be found. In this article we present and evaluate a conceptual approach to scenario building aimed at transdisciplinary learning for sustainable water governance. The approach combines normative, explorative, and participatory scenario elements. This combination allows for adequate consideration of stakeholders’ and scientists’ systems, target, and transformation knowledge. Application of the approach in the MontanAqua project in the Swiss Alps confirmed its high potential for co-producing new knowledge and establishing a meaningful and deliberative dialogue between all actors involved. The iterative and combined approach ensured that stakeholders’ knowledge was adequately captured, fed into scientific analysis, and brought back to stakeholders in several cycles, thereby facilitating learning and co-production of new knowledge relevant for both stakeholders and scientists. However, the approach also revealed a number of constraints, including the enormous flexibility required of stakeholders and scientists in order for them to truly engage in the co-production of new knowledge. Overall, the study showed that shifts from strategic to communicative action are possible in an environment of mutual trust. This ultimately depends on creating conditions of interaction that place scientists’ and stakeholders’ knowledge on an equal footing.

Food Volume Computation for Self Dietary Assessment Applications

There is great demand for easily-accessible, user-friendly dietary self-management applications. Yet accurate, fully-automatic estimation of nutritional intake using computer vision methods remains an open research problem. One key element of this problem is the volume estimation, which can be computed from 3D models obtained using multi-view geometry. The paper presents a computational system for volume estimation based on the processing of two meal images. A 3D model of the served meal is reconstructed using the acquired images and the volume is computed from the shape. The algorithm was tested on food models (dummy foods) with known volume and on real served food. Volume accuracy was in the order of 90 %, while the total execution time was below 15 seconds per image pair. The proposed system combines simple and computational affordable methods for 3D reconstruction, remained stable throughout the experiments, operates in near real time, and places minimum constraints on users.
