« What a piece of work is your machine, Harold » : Shakespeare et la réinvention de l’humanité dans les séries américaines d’anticipation
Authors: Hatchuel Sarah
Published: January 2019

Si Harold Bloom a pensé Shakespeare, de manière relativement essentialiste, comme l’inventeur de ce qu’on entend par « humain », les séries télévisées américaines présentent Shakespeare comme ce qui définit une humanité en permanente re-définition, re-construction ou ré-affirmation. Shakespeare est convoqué non pas pour définir l’humain de manière fixe mais pour contribuer à une extension du domaine de l’humain. Dans des séries de science-fiction et d’anticipation comme Star Trek, Person of Interest ou Westworld, les mots de Shakespeare deviennent les signes par lesquels les machines et les anthropoïdes révèlent qu’ils acquièrent une humanité ou peut-être même qu’ils étaient toujours déjà humains. Le dialogue qui s’instaure entre Shakespeare et les séries « posthumaines » fait écho à celui qui s’était déjà établi dans le film Elephant Man réalisé en 1980 par David Lynch, réalisateur qui a lui-même fait des allers-retours entre le cinéma et les séries télévisées.

Authors: Caponnetto Pasquale , Magro Rosanna , Inguscio Lucio , Cannella Maria Concetta
Published: January 2019

Emergency room have particularly stressful work situations. Emergency room personnel cope with stressors on a daily basis. These stressors can be risks factor for burn out and for reduced quality of life and work motivation. Emergency room staff of one of ASP 3 CT urban hospital in Acireale, Italy participated to stress management program by autogenic training twice a month for 16 weeks. This program were prepared based on existing research and studies, and were conducted by clinical psychologists. We found that the mean value in pre-test is significantly different from mean value in post-test for: Perceived Stress Scale PPS (t=7.72 with 27 df and P<0.001); Euro Quality for life (t=-14,13 with 27 df and P<0.001); Work motivation assessed by Visual Analogue scale VAS (t=-4.52 with 27 df and P<0.001). In the Maslach Burnout Inventory, the mean value is significantly different for emotional exhaustion sub-scale (t=5.64 with 27 with 27 df and P<0.001) and for depersonalization subscale (t=6.67 with 27 df and P<0.001). No significant difference was observed for the personal accomplishment sub-scale. This research suggests that psychological interventions with emergency room staff are effective. Our study showed effectiveness of an autogenic and stress management training in improvement of quality of life, work motivation, burn-out and stress perceptions for emergency department team.
Affine Yangian Action on the Fock Space
Authors: Kodera Ryosuke
Published: January 2019

The localized equivariant homology of the quiver variety of type

A_{N-1}^{(1)}

can be identified with the level one Fock space by assigning a normalized torus fixed point basis to certain symmetric functions, Jack(

\mathfrak{gl}_N

) symmetric functions introduced by Uglov. We show that this correspondence is compatible with actions of two algebras, the Yangian for

\mathfrak{sl}_N

and the affine Lie algebra

\hat{\mathfrak{sl}}_N

, on both sides. Consequently we obtain affine Yangian action on the Fock space.
CEO-CLER Innovation Grants Program: Empowering Residents as Clinical Learning Environment Change Agents
Authors: Batalden Maren , Fisher Carolyn , Pels Richard , Gaufberg Elizabeth
Published: January 2019

Background 

Many efforts over the past decade have focused on developing quality improvement and safety curricula for residents. Sponsoring institutions have encountered challenges aligning resident projects with institutional quality and safety priorities, engaging faculty mentors, and securing support for resident initiatives from executive leadership.

Objective 

We developed a small grants program to support resident-led change projects intended to improve the clinical learning environment. We assessed program acceptability to residents and faculty, impact of program structure in supporting successful change projects, and program feasibility and financial sustainability.

Methods 

Program acceptability was assessed through a review of resident participation. Three aspects of resident change project success were considered: (1) accomplishment of stated aims; (2) institutional change beyond the end of grant funding; and (3) academic publication or presentation. The impact of program structure on project success was assessed through a review of submitted end-of-year narrative reports.

Results 

The Award Selection Committee has given 41 awards to 44 residents over 4 years, engaging 21% (44 of 213) of residents. Seventy-one percent of projects (29 of 41) produced changes that continued beyond the grant year, and 46% (19 of 41) produced an academic publication or presentation. At the end of the grant period that funded the program's initial 3 years, the chief executive officer elected to continue program funding.

Conclusions 

A small grants program supporting resident-led change projects intended to improve the clinical learning environment is acceptable to residents and faculty, feasible to administer, and sustainable with support from institutional senior leaders.
ACGME Milestones Within Subspecialty Training Programs: One Institution's Experience
Authors: Heath Janae K. , Dine C. Jessica
Published: January 2019

Background 

The Accreditation Council for Graduate Medical Education Milestones were created as a criterion-based framework to promote competency-based education during graduate medical education. Despite widespread implementation across subspecialty programs, extensive validity evidence supporting the use of milestones within fellowship training is lacking.

Objective 

We assessed the construct and response process validity of milestones in subspecialty fellowship programs in an academic medical center.

Methods 

From 2014–2016, we performed a single center retrospective cohort analysis of milestone data from fellows across 5 programs. We analyzed summary statistics and performed multivariable linear regression to assess change in milestone ratings by training year and variability in ratings across fellowship programs. Finally, we examined a subset of Professionalism and Interpersonal and Communication Skills subcompetencies from the first 6 months of training to identify the proportion of fellows deemed “ready for independent practice” in these domains.

Results 

Milestone data were available for 68 fellows, with 75 933 unique subcompetency ratings. Multivariable linear regression, adjusted for subcompetency and subspecialty, revealed an increase of 0.17 (0.16–0.19) in ratings with each postgraduate year level increase (P < .005), as well as significant variation in milestone ratings across subspecialties. For the Professionalism and Interpersonal and Communication Skills domains, mean ratings within the first 6 months of training were 3.78 and 3.95, respectively.

Conclusions 

We noted a minimal upward trend of milestone ratings in subspecialty training programs, and significant variability in implementing milestones across differing subspecialties. This may suggest possible difficulties with the construct validity and response process of the milestone system in certain medical subspecialties.
Szkic aktualnej debaty nad naukometrią i bibliometrią w Polsce i zapomniane naukoznawstwo
Authors: Kokowski Michał
Published: January 2019

In the debate on scientometrics and bibliometrics, taking place in Poland in the last 25 years, a very serious methodical and methodological mistake has been committed by neglecting the reflection about the science of science, especially of historical and methodological character. The following article discusses this issue. This aim was achieved with the use of a method of interdisciplinary research originating from the scope of the science of science and the history of the science of science. This method was applied to the analysis of selected major publications on scientometrics and bibliometrics in the past 25 years, with special emphasis on Polish context. The results are discussed in the article, i.e. a) the context of the current debate on scientometrics and bibliometrics in Poland; b) the history of Polish scientometric analyses based on foreign indexation databases; c) the current discussion on scientometrics and bibliometrics in Poland and d) the key aspect ignored in the current debate, namely the inseparable connection of scientometrics and bibliometrics with the science of science. The study leads to the following conclusions: it is postulated that the informetric (scientometric, bibliometric, Webometric, etc.) studies return to the scientific discourse, which would be consciously developed in the context of the integrated science of science. This knowledge should be utilized in the development of the current science policy, i.e. the organizational structure of science and higher education and the formation of rules of appraisal of scientific institutions, individual employees and scientific journals.

Authors: Dantas José Alves , Barreto Igor Theodoroviz , Carvalho Paulo Roberto Matos
Published: January 2019

Este estudo teve por objetivo avaliar se a emissão de relatório de auditoria com opinião modificada impacta a sequência do contrato entre auditor e cliente, bem como se o fato da firma de auditoria ser uma big four ou a empresa auditada adotar práticas de governança corporativa reduz o risco de descontinuidade da relação contratual, mesmo com a emissão de opinião modificada. Testes empíricos realizados com base nos relatórios de auditoria, de 2009 a 2015, de 338 empresas listadas na BM&FBovespa revelaram que no âmbito do mercado de capitais brasileiro: há relação positiva entre a opinião modificada e a troca do auditor no período seguinte; e o fato da firma de auditoria ser uma big four ou a empresa cliente pertencer aos segmentos de governança corporativa do mercado não reduzem esse risco de descontinuidade contratual entre as partes, nos casos de emissão de opinião modificada.

Published: January 2019

O objetivo deste artigo é analisar as principais mudanças organizacionais ocorridas com o processo de implementação do IFRS, categorizando os impactos encontrados em relação aos elementos de mudanças descritos por Mintzberg e Westley (1992, pp.40-41): cultura, estrutura, sistemas e pessoas. A estratégia de pesquisa foi um estudo de caso múltiplo, em 2011, em três empresas. O IFRS trouxe integração da área contábil com áreas fornecedoras de informações financeiras; o conselho de administração envolveu-se nessas mudanças, a área contábil ficou mais próxima do investidor e passou a conduzir consultorias financeiras; no entanto, houve desgaste no relacionamento com clientes devido a tantas novas exigências de mensuração. Houve grandes mudanças em sistemas, observou-se um maior uso de informações gerenciais na confecção de demonstrações financeiras e mudanças em covenants em função de novos critérios contábeis. Foi possível perceber alterações no perfil profissional do contador e de áreas fornecedoras de informações financeiras.

O artigo pretendeu responder questão ligada ao nível de uso e de relevância atribuída aos indicadores não financeiros e às informações oriundas destes. Foi empregada metodologia descritiva, com abordagem quantitativa e coleta de dados por intermédio de survey. Após revisão da literatura sobre o tema, foram apresentadas as principais características das 207 empresas participantes do estudo. Os dados coletados foram evidenciados e comentados segregando as respostas em dois grupos (indústrias e comércio/serviços). Quanto à utilização de indicadores não financeiros, com base no teste estatístico aplicado concluiu-se que há divergência nos níveis de uso desses indicadores se comparadas as empresas fabris e as não fabris. Em relação à importância atribuída constatou-se que não há diferença estatisticamente relevante entre os dois conjuntos de empresas. Por outro lado, percebeu-se que as empresas de menor porte tendem a utilizar menos e a dar menor importância aos indicadores não financeiros do que as firmas de maior porte.
In vitro analysis of urinary stone composition in dual-energy
computed tomography
Authors: Stępień Monika , Chrzan Robert , Gawlas Wojciech
Published: January 2019

Purpose

Dual energy computed tomography (DECT) is a new method of computed tomography (CT) imaging, allowing the assessment of not only the object’s morphology, but also its composition. The aim of the study was to evaluate the potential of in vitro DECT evaluation of urinary stones’ chemical composition.

Material and methods

Six samples of surgically removed renal stones were scanned using DECT and analyzed by scanner vendor software. Uric acid stones were marked red and calcium stones white by the software. The real composition of the stones was finally verified using physicochemical laboratory analysis.

Results

In 5 out of 6 samples, the composition of stones in DECT (3 samples identified as uric acid and 2 samples as calcium) was consistent with the physicochemical analysis (3 samples identified as uric acid, 1 as calcium phosphate, 1 as calcium oxalate). In DECT it was not possible to determine more precisely the type of calcium compounds (calcium phosphate vs. calcium oxalate) as established in the physicochemical analysis.
In one stone identified in physicochemical analysis as uric acid, DECT detected a composite layered structure containing both uric acid and calcium compounds.

Conclusions

DECT allows uric acid to be distinguished from calcium urinary tract stones, which is crucial in the choice of appropriate therapy. Using the available hardware and software, it was not possible to more accurately distinguish types of calcified stones. Evaluation of the stone type in DECT may be limited in the case of mixed chemical composition.
Ruptured intracranial dermoid cysts: a pictorial review
Authors: Jacków Jagoda , Tse George , Martin Andrew , Sąsiadek Marek , Romanowski Charles
Published: January 2019

Intracranial dermoid cysts are rare, benign, congenital, slow-growing cystic lesions. They are composed of mature squamous epithelium and can contain apocrine, eccrine, and sebaceous glands as well as other exodermal structures. Rupture of intracranial dermoid cysts is a relatively uncommon phenomenon but can cause more serious complications such as chemical meningitis, vasospasm, and cerebral infarction. Understanding of the appearance of both unruptured and ruptured dermoid cysts on computed tomography and MRI, especially awareness of existing low signal “blooming artefacts” on certain sequences, aids diagnosis and referral to the proper specialty for appropriate treatment.

Authors: Sureka Binit , Meena Virendra , Garg Pawan , Yadav Taruna , Khera Pushpinder Singh
Published: January 2019

Gynaecological malignancies are the most common malignancies in women and also an important public health issue. In developing countries, there is a paucity of screening facilities and cancer awareness, so patients present at an advanced stage of disease, which severely limits the prognosis and clinical outcome. Among the gynaecological malignancies, ovarian malignancy has the second highest incidence in women according to the incidences. Ovarian malignancy is usually diagnosed at the advanced stages, and to improve the patient’s survival, debulking surgery is very important. Advanced-stage disease is treated with either debulking surgery followed by adjuvant chemotherapy or initial neoadjuvant chemotherapy followed by debulking surgery. Imaging is very important in patient selection, in determining who will benefit from neoadjuvant chemotherapy just before debulking surgery. This article highlights the role of computed tomography (CT) in the detection of patterns of spread of ovarian malignancy, important for staging and management.
Improved imaging of colorectal liver metastases using single-source fast kVp-switching dual-energy CT: preliminary results
Authors: Ratajczak Przemysław , Serafin Zbigniew , Sławińska Agata , Słupski Maciej , Leszczyński Waldemar
Published: January 2019

Purpose

Computed tomography remains the first-choice modality for assessment of colorectal cancer liver metastases (CRLM). Dual-energy computed tomography (DECT) is a relatively new technique that is becoming increasingly available. One of the advantages of DECT is the ability to maximise iodine detection. Our aim was to test whether single-source, fast kVp-switching DECT can improve imaging quality of CRLM compared to conventional (polychromatic) CT.

Material and methods

Twenty consecutive patients were enrolled into a preliminary prospective study. The scanning protocol consisted of four phases: non-contrast with standard 120 kV tube voltage and three post-contrast phases with rapid voltage switching. As a result, three sets of images were reconstructed: pre- and postcontrast polychromatic (PR), monochromatic (MR), and iodine concentration map (IM). To compare the sensitivity of the tested reconstructions, the number of CRLMs and the maximum diameter of the largest lesion were calculated. Objective image quality was measured as signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR). The radiation dose was expressed as CTDIvol.

Results

Imaging was successfully performed in all patients. The number of detected lesions was significantly lower on PR images than on IM and MR 50-70 keV (mean number: 4.20 and 4.45, respectively). IM and MR at 70 keV presented the highest quality. SNR was significantly higher for IM and 70 keV images than for other reconstructions.
The mean radiation dose was 14.61 mGy for non-contrast 120 kV scan and 17.89 mGy for single DECT scan (p < 0.05).

Conclusions

DECT is a promising tool for CRLM imaging. IM and low-photon energy MR present the highest differences in contrast between metastases and the normal liver parenchyma.

Published: January 2019

Abstract. Brown carbon (BrC) is a type of light-absorbing component of organic aerosol (OA), covering from near-ultraviolet (UV) to visible wavelength ranges, and thus may cause additional aerosol radiative effect in the atmosphere. While high concentrations of OA have been observed in the Pearl River Delta (PRD) region of China, optical properties and the corresponding radiative forcing of BrC in PRD are still not well understood. In this work, we conducted a set of comprehensive measurements of atmospheric particulate matters from 29 November 2014 to 5 January 2015 to investigate aerosol composition, optical properties, source origins and radiative forcing effects at a suburban station of Guangzhou. Particle absorption Ångström exponent (AAE) was deduced and utilized to differentiate light absorption by BrC from black carbon (BC). The results showed that the average absorption contributions of BrC were 25.9 ± 9.0 % at 370 nm, 19.7 ± 7.9 % at 470 nm, 14.1 ± 6.9 % at 520 nm, 11.6 ± 5.6 % at 590 nm and 7.7 ± 4.4 % at 660 nm, respectively. A sensitivity analysis of the evaluation of absorption Ångström exponent of BC (AAEBC) was conducted based on the Mie theory calculation, assuming that the BC-containing aerosol was internally mixed, with a core-shell configuration. The corresponding uncertainty of BrC absorption contribution was acquired. We found that variations in the imaginary refractive index (RI) of BC core can significantly affect the estimation of BrC absorption contribution. However, BrC absorption contribution was relatively less sensitive to the real part of RI of BC core and was least sensitive to the real part of RI of non-light absorbing shell. BrC absorption was closely related to aerosol potassium cation content (K+), a common tracer of biomass burning emission, which was most likely associated with straw burning in the rural area of western PRD. Diurnal variation of BrC absorption revealed that primary organic aerosol had a larger BrC absorption capacity than secondary organic aerosol (SOA) had. Radiative transfer simulations showed that BrC absorption may cause 2.2 ± 2.3 W m−2 radiative forcing at the top of atmosphere (TOA) and contribute 14.2 ± 6.2 % of the aerosol warming effect. A chart was constructed to conveniently assess the BrC radiative forcing efficiency in the studied area with reference to a certain aerosol single-scattering albedo (SSA) and BrC absorption contribution at various wavelengths. Evidently, BrC radiative forcing efficiency was higher in shorter wavelength.
Bio-purification of drinking water by froth flotation
Authors: Hassan Ghanim , Edyvean Robert
Published: January 2019

Abstract. The main technique for removing bacteria from water for various applications is chemical disinfection. However, this method has many disadvantages such as producing disinfectant by-products (DBPs), biofilm formation and either rendering the water unpotable (at high residual disinfection) or leaving a potential for lethal diseases such as Cholera (if the residual disinfection is too low). Recently, a process was developed for continuous removal of bacteria from water using the principle of froth flotation through compressed air only without any chemicals (Hassan, 2015). This work examines the extent to which chemical free froth flotation can purify drinking water. The experiments were carried out using two flotation columns with different column lengths, each equipped with ceramic air sparger. Raw water containing bacteria was fed into the column from the top. Air was pumped through the water enough to produce a froth which separated the bacteria and, when removed, the bacterial content measured. The results show that the bacterial concentration can be reduced by 55% of its original concentration under the optimal experimental conditions so far found. This suggests that the technique can be used as a pre-purification step to minimize the use of disinfectants; hence their byproducts, and to control biofilm growth.
A library mobile device deployment to enhance the medical student experience in a rural longitudinal integrated clerkship
Authors: Johnson Emily M. , Howard Carmen
Published: January 2019

Objective: Investigators implemented the Rural Information Connection (RIC) project, a library-initiated deployment of iPad Mini 3s for third-year medical students who were enrolled in a seven-month rural longitudinal integrated clerkship (LIC) rotation. The research aims were to determine if devices preloaded with high-quality mobile health apps enhanced the experience and increased access to and awareness of mobile health information resources for the enrolled project participants.Methods: Nine participants enrolled in this mixed methods research project. Pre- and post-survey and structured learning journals (SLJs) were used for data collection on device and app use. Descriptive statistics and thematic coding analysis included data from seven pre-surveys, nine post-surveys, and sixty-four SLJ prompts. The validated Technology Acceptance Model instrument was also incorporated to gauge the devices’ integration into the participants’ workflow.Results: The investigation indicated that the iPad Mini 3 and resources were utilized and integrated at varying levels in the participants’ workflow. Reported use of health information apps suggests a preference for broad-based information sources rather than specific or specialized information resources. Participants performed several tasks on the device, including seeking background information, educating patients, and managing rotation schedules. Participant reflections indicated positive experiences utilizing the device and health information resources, which enhanced their rural LIC rotations.Conclusions: The research analysis demonstrates the information-seeking behavior of medical students immersed in a rural environment and indicates an acceptance of mobile technology into the workflow of participants in this project. Mobile device deployments offer great opportunities for librarians to design innovative programming in medical education.
Building new twenty-first century medical school libraries from the ground up: challenges, experiences, and lessons learned
Authors: Dexter Nadine , Muellenbach Joanne M. , Lorbeer Elizabeth R. , Rand Debra , Wilcox Matthew E. , Long Bradley A.
Published: January 2019

The twenty-first century library at a newly opened medical school often differs from those at traditional medical schools. One obvious difference is that the new medical school library tends to be a born-digital library, meaning that the library collection is almost exclusively digital. However, the unique issues related to building a library at a new medical school are not limited to online collections. A unique start-up culture is prevalent, of which newly appointed directors and other library and medical school leaders need to be aware. This special paper provides an overview of best practices experienced in building new medical school libraries from the ground up. The focus is on the key areas faced in a start-up environment, such as budgeting for online collections, space planning, staffing, medical informatics instruction, and library-specific accreditation issues for both allopathic and osteopathic institutions.

Civilização, violência e educação: uma leitura a partir de Freud e Adorno
Authors: Pereira dos Santos Dayanna
Published: January 2019

Este artigo propõe a reflexão sobre alguns pontos do pensamento de Adorno e Horkheimer e da teoria freudiana, destacando-se a temática da existência e da violência na tensão entre a coletividade e a individualidade. Para tanto, busca-se identificar as raízes do conflito entre as pulsões e a cultura e a forma que a repressão comparece na civilização. Sob esse marco teórico, a reflexão sobre indivíduo-sociedade terá como objetivo realçar tramas e enlaces aparentes e abstrusos operantes no processo civilizatório em resistência e oposição à consubstancialização do sujeito com a realidade exterior e os votos de violência prenunciados pela sociedade capitalista.

Os discursos e os dilemas da formação estética entre emancipação e barbárie
Authors: Torres Pereira Márcia
Published: January 2019

O presente artigo objetiva uma discussão sobre as contribuições das narrativas verbais em prosa e não verbais na formação de sujeitos em seu sentido estético e transcorre pela reflexão sobre os processos identificatórios e societários que sofrem interferências da indústria cultural, ancorada nos seguintes autores da teoria crítica da sociedade Theodor Adorno [1903-1969] e Max Horkheimer [1895-1973], considerando a relação entre universal e particular, teoria e prática, forma e conteúdo, sujeito e objeto como procedimento metodológico da dialética negativa. Destacam-se neste texto os fenômenos que incidem sobre as (im)possibilidades de os sujeitos realizarem a experiência da reflexão no sentido de investigar e apresentar as condições que legitimam as narrativas com fins à emancipação e à barbárie.
Violência e juventude em Goiás: narrativas dos jovens de escolas públicas
Authors: Fábia Alves Miriam
Published: January 2019

Objetivamos analisar a narrativa dos jovens das escolas públicas de Goiás acerca das relações entre violência e juventudes. As narrativas foram obtidas por meio da realização de rodas de conversa e questionário com 271 jovens do 3o ano do ensino médio de escolas estaduais em quatro cidades goianas marcadas por altos índices de violência: Aparecida de Goiânia, Goiânia, Luziânia e Rio Verde. Pode-se concluir que as narrativas dos jovens revelam matizes importantes para compreender o fenômeno da violência juvenil, pois de um lado ecoa o discurso hegemônico de que o jovem é violento, e de outro, narrativas que reconhecem os jovens como vítimas do sistema e apontam a importância das instituições e da ação estatal para o enfrentamento da violência.
Aspectos estruturais da violência no campo: uma revisão bibliográfica a partir do caso brasileiro
Authors: Maria Magalhães Lopes Cerqueira Juliana , Dantas Vieira Denes
Published: January 2019

A história do campesinato brasileiro é marcada por episódios brutais de violência. De Canudos a Eldorado dos Carajás, a violência tem se constituído enquanto fenômeno presente no âmbito rural, atingindo altos índices em períodos determinados. Em 2016, dados revelaram um aumento da violência no campo no Brasil. Este artigo, tem como objetivo investigar as raízes desta violência para compreender a elevação das estatísticas atualmente. O estudo, consiste em uma revisão bibliográfica, baseada, sobretudo, em obras de estudiosos como José de Souza Martins (1990) e Leonildes Sérvulo de Medeiros (2002), com foco maior na trajetória de conflitos sociais das décadas de 1950 a 1990. Os resultados da pesquisa mostram que a violência é fruto da própria formação do campesinato brasileiro e reproduz praticamente as mesmas estruturas ao longo da formação política, econômica e social brasileira.

A dor se manifesta com continuidade na vida de atletas, produz formas através das quais estes se relacionam com o esporte, consigo. Buscaremos compreender as modulações subjetivas da dor, os ecos e significações advindos dessa experiência continuada nas perspectivas cognitivas e comportamentais em atletas de modalidades individuais cujo componente estético constitui indicador de desempenho e excelência.  Este ensaio discute o papel das interpretações que modulam a figura do atleta e da dor, não reduzida a uma realidade estritamente biológica.

Sophia Chambers, Founder of the Holiness Church: A Case Study of Victorian Entrepreneurial Religious Leadership
Authors: Bundy David
Published: January 2019

The Holiness Church, founded by Sophia Chambers (1838–87), is one of the rare religious denominations in any country founded and led by a woman. The central primary source is the periodical created and edited by Chambers, the Holiness Advocate. The article argues that Sophia Chambers's leadership approach provides an additional exception to common scholarly conceptions of women's ministry, leadership, and gender roles of the late Victorian period. To make this argument, the extant sources for Sophia Chambers and the Holiness Church are provided, narratives of her life and of the history of the Holiness Church during her lifetime are reconstructed, and her theological framework is examined. At her death, she left the leadership in the hands of four of her male subordinates. The developments in the transition of power and their effect on the church are examined before reflecting on her approach to leadership. It demonstrates that the ‘two spheres’ paradigm is not adequate for understanding Chambers.

This paper evaluates some geochemical properties of trace metals in peri-urban drainage and bioaccumulation in cassava, plantain, lettuce and sugarcane in the Kumasi metropolis in Ghana, West Africa. The aim is to establish water quality and food safety. Water, sediment and the food crops were sampled along the profiles of Wiwi and Subin rivers for analysis. T-test statistic shows that pH, HCO3, Cl, Cu, As, Pb and Ni are significant in water and sediment. Mean concentrations of Cu, As, Pb and Ni in water and sediment are (0.01mg/l; 3.2mg/kg), (3.08mg/l; 4.9mg/kg), (0.034mg/l; 8.7mg/kg) and (0.021mg/l; 6.1mg/kg), respectively. In water, As, Pb and Ni concentrations are above primary maximum contamination limits of 0.05 mg/l, 0.015 mg/l and 0.020mg/l with metal ratios of 61.54, 2.27 and 1.05, respectively. In sediment, As concentration is above the continental crustal background value of 1.8mg/kg with a metal ratio of 2.72. From geochemical process models: (1) As and Ni adsorbs into sediment and may lead to attenuation in water in closed systems; (2) Cu and Pd are in equilibrium and may affect water quality at higher concentrations. The food crops have trace metals concentrations below reference values and bioaccumulation factors<1. The food crops are therefore excluders, and safe for dietary intake. Members in cassava-plantain-lettuce and cassava-lettuce-sugarcane suites have translocation factors (TFs)>1 for Cu and As, respectively, while lettuce has TF>1 for Pd and Ni. Crops with TF>1 may bioaccumulate the respective trace metals in over a prolonged period.

Rising interests to support green development through targeted conservation approaches in the developing world attracted international NGO attention especially in the 1990s. One of such NGOs, the World-Wide Fund for Nature (WWF) has been backstopping many African nations in the process of realizing the twin objectives of livelihood sustenance and protected area conservation. In the case of Cameroon, one of her key areas of intervention has been the introduction of green business initiatives as a way of strengthening the link between livelihood support and conservation in protected areas. With a focus on Cameroon, we review the green business model (Note 1) as a WWF intervention approach in Africa. We undertake a random survey of household representatives drawn from 7 WWF conservation cooperatives in Cameroon on their perceptions and preferences with regards to the green business initiative. This was complemented by interviews to 8 WWF and partner CSO representatives, and field observations. The results are discussed to include a schema of the green business approach in Africa with a focus on Cameroon, cooperative members’ knowledge levels of the initiative, impact of the initiative and clarity of benefit sharing schemes in place, among others. The pairwise correlation shows a strong positive relationship between knowledge/experience levels and a number of elements including shortcomings of the initiative, the need for strategy improvement, and the tendency for outside influence on the green business choices. This aspect equally showed a strong positive correlation with the need to switch to other green business options and unclear benefit sharing. In conclusion, we argue for a shift in the green business approach to capture issues of improvement in knowledge levels, diversification, technical and institutional capacity building, clarity of benefit sharing, and value chain development. We further advocate for a green business approach in tandem with the aspirations of local populations around protected areas on the one hand, and the need for a conservation cooperative alliance on the other hand. The results contribute to the “green economy” discourse which has significantly gained grounds in all spheres of conservation and development interventions.
Cost Benefit Analysis of Growing Cucumbers in Greenhouse at Different Cooling of Nutrient Solution Temperatures in Closed Hydroponic System in Oman
Authors: Rawahy Muthir Saleh Said Al , Mbaga Msafiri Daudi
Published: January 2019

Oman is a country that is mostly dry and hot, with daily maximum temperatures easily reaching 40°C or more during summer. The Oman weather therefore renders conventional open field agriculture almost impossible. The sustainable future of agriculture in Oman and other similar desert countries will therefore depend very much on the adoption of land and water saving technologies such as greenhouses and soilless culture or hydroponics. Soilless culture (Hydroponics) is the technique of growing plants without soil with their roots immersed in nutrient solution. Among factors affecting hydroponic production systems, is the nutrient solution temperature which is considered to be one of the most important determining factors of crop yield and quality. The aim of this research is therefore to investigate the economic effect of cooling nutrient solutions temperature technique on cucumber output. Four nutrient solutions temperatures are investigated and a Cost Benefit Analysis is undertaken. Results indicate that all the four cooling nutrient temperature yields positive returns (benefits) above variable and total costs for the two years of this experiment. Cooling nutrient temperature (22ºC) yields higher returns than the other treatments followed by treatment (25ºC), (28ºC) and then the CONTROL treatment. Returns for the second year are higher than the first year. Therefore treatment (22ºC) was observed to be the best overall producing the highest return above variable and total costs. It is therefore considered the best alternative for cucumber growers.

It is a well known, that the physical activity promotes mental health. Physically active people relatively rarely suffer from psychosomatic and depressive disorders. It is possible that the differences in gene activity in peripheral blood leukocytes may be associated with depression, especially genes participating in inflammatory response. Thus, the aim of our study was to investigate the levels of IL6 and IL10 mRNA and IL10/IL6 ratio in peripheral blood leukocytes in healthy, physically active individuals.

One hundred healthy young men (20-23 years old) participated in this study. All of them declared regular physical activity. Participants were non-smokers, and consumed alcohol occasionally. To access genes expression, 2 ml of venous blood was collected. RNA isolation was performed and then the relative expression of IL6 and IL10 was calculated using quantitative real-time polymerase chain reaction (Q-RT-PCR). Pro and anti-inflammatory balance was calculated as 2^relative of IL10/ 2^relative expression of IL6.

Low expression of tested genes was found in healthy young men. Mean expression for IL6 was 2^0.051 (n=90) and for IL10 2^0.08 (n=98). Mean ratio IL10/IL6 was 2^1.58.

Higher expression of IL10 compared to IL6 may be essential not only for the physical performance but also for the mental health. Diverse reports in the literature may be associated with choosing various control groups, i.e. sedentary or older individuals. It is possible, that measuring the expression of IL6 and IL10 (especially the ratio IL10/IL6) in peripheral blood leukocytes may be useful in the assessment of depressive disorders. Thus, molecular study of active young men can confirm the need for physical activity among people suffering from depression, but further studies are needed, particularly among people with psychosomatic disorders.

Published: January 2019

W artykule przedstawiono rolę mediów cyfrowych w życiu codziennym człowieka oraz ich wpływ na kształtowanie jego postaw oraz zachowania. Zwrócono uwagę na szczególną rolę jaką w relacjach rodzinnych odgrywa powszechne korzystanie ze współczesnych technologii komunikacji. Podkreślono jak bardzo zmieniły się relacje pomiędzy rodzicami i dziećmi w wyniku gwałtownie rozwijającej się techniki telefonów komórkowych i najnowszej ich wersji w postaci smarfonów. Dzięki smartfonom jest możliwy powszechny dostęp do Internetu, który jest źródłem zarówno informacji jak również pozwala wykorzystać różne komunikatory do wzajemnych kontaktów. Ten szeroko pojęty dostęp do środowiska cyfrowego ma bardzo pozytywne znaczenie w naszym życiu codziennym, niestety niesie również pewne zagrożenia wynikające przede wszystkim z bezkrytycznego korzystania z zasobów Internetu. Artykuł zawiera ponadto wyniki własnych badań statystycznych dotyczących wpływu Internetu na relacje rodzinne, które przeprowadziła autorka w rejonie Iwano Frankiwska na Ukrainie.
