Authors: Campos Suzana Oliveira , Scorsolini-Comin Fabio
Published: March 2021

O adoecimento por câncer ginecológico apresenta repercussões significativas nas vidas das pacientes, bem como de seus cônjuges/parceiros. Para fazer frente a esse processo, esses casais podem desenvolver estratégias de enfrentamento (coping) que incluam ou não a conjugalidade. O objetivo deste estudo de casos múltiplos foi conhecer as principais fontes de apoio e as estratégias de enfrentamento desenvolvidas por casais em que a esposa/companheira realizou tratamento do câncer de colo uterino. As evidências foram produzidas a partir de três estudos de caso, com o emprego de entrevistas individuais com cada cônjuge e também com o casal. As entrevistas transcritas foram analisadas pela Psicologia Positiva. A família foi considerada a principal rede de apoio. As estratégias de coping mais utilizadas foram: ressignificação do problema e suporte religioso/espiritual. A religiosidade/espiritualidade permitiu a construção de significados acerca do adoecer e a atribuição de um sentido de gratidão em decorrência dos aprendizados. O reconhecimento desses aspectos pode levar ao desenvolvimento de intervenções alinhadas às vivências dos casais e à oferta de um cuidado mais adequado.

Authors: Sudalaimani C. , Sivakumaran N. , Devanand P. , Alexander G. , Valsalam S. Rominus
Published: March 2021

Epileptic seizure in the brain affects the day-to-day life of any individual due to its unexpected nature of occurrence. It has affected more than 50 million people worldwide. Drug resistance of patients is an important factor which leads to failure of epilepsy treatments using medications in 30% of patients. Surgery is also not a viable option in a substantial number of patients. In such cases, a new kind of seizure forecasting system is necessary to help those people. In our work, various sub-frequency bands of EEG signals are produced from the originally recorded Intracranial Electroencephalogram (IEEG) signals of five canines and two persons to identify possible low complex and less intense EEG features from each sub-band of the entire spectrum. Support Vector Machine (SVM) with different Kernel-based classifiers are used to categorize features into preictal and interictal data. Epileptic Seizures forecasting accuracy of 99% has been achieved for data from canine and human. Employed wavelet filter for noise removal and found that it improved the seizure prediction accuracy in some subjects and reduced the accuracy in some subjects. Similarly, the feature selection technique also improved the preictal detection accuracy in some patients/subjects and reduced the accuracy in some data. From this work, we identified that seizure prediction is possible in at least one sub-frequency band especially in high gamma sub-band generated from the originally recorded signal using a high-pass filter. This work demonstrates an algorithm for seizure forecasting or identifying the preictal region which identifies the suitable best sub-frequency band for predicting the seizure of the originally recorded EEG data by using the computationally less intense EEG features and employing the best classifying SVM kernel.
The Role of Organizational Information Systems in the Digital Transformation Process of Public Services
Authors: Koç Hatice
Published: March 2021

In the information age, ICTs are transforming all areas of life. States produce policies, make investments, and develop projects in order to use this transformation for the benefit of their citizens. E-transformation of the state requires the transformation of public services and service providers. For this reason, public institutions are important actors in e-transformation, preparing both their structures and services and citizens for information technologies. In Turkey, as in the institutions of the world, the need for information management systems emerged in order to increase the service quality of public institutions, to carry organizational knowledge from the past to the future, to ensure continuity in a more effective public administration. In this study, the current legal regulations are examined; also, in the case of Atatürk, Culture Language and History Supreme Council, the digitalization of service processes of institutions through organizational information systems were examined, and the contribution of institutions to e-transformation was investigated.
Folk Values for Beginners
Authors: Tasnim Saria , Hossain Amzad
Published: March 2021

The inherently diverse folkloric values are the applied aspects of folk philosophy. Amongst these values, the paper focusses on a few specific tenets that are transplanted in the beginners' hearts to counteract the current culture of thriving consumption that instigates competition and greed, profit-making use of science and technology, and moral degradation. These values are also linked to the globalisation of sustainability education to counteract the destruction of the natural and social environment. They need major attention right from the primary level of education. Using the case study of Bangladesh, the paper presents a synopsis of the core folkloric tradition of the country and critically analyses the substantial impact of folk values on the daily lives of its inhabitants as well as discusses how these values can contribute to sustainability.
Health Information Systems (HIS) Privacy Restrictions for GDPR
Authors: Carvalho Marcelo , Bandiera-Paiva Paulo , Marques Eduardo , Machado José Manuel
Published: March 2021

The personal health information (PHI) that a health information system (HIS) stores and processes requires special caution to ensure authorized manipulation by system users. A diverse set of best practices, standards, and regulations are in place nowadays to achieve that purpose. To the access control element in a HIS, general data protection regulation (GDPR) will require explicit authorization and informed consent prior to this manipulation of patient information by healthcare practitioners in a system. The adaptations to cope this type of previous authorization on HIS requires not only a clear understanding of technicalities and modification to the underlying computational infrastructure but also the impact on players that interact with this type of system during healthcare service provision, namely patients and healthcare professionals. This article is an effort to understand this effect by means of collecting opinion from both players in a multicentric survey that presents different questions establishing scenarios that reflect this new control and its consequences.
The Use of Static Telecytological Applications for Proficiency Testing Purposes in the Field of Diagnostic Cytopathology
Authors: Archindakis Stavros K.
Published: March 2021

Over the last decade, the practice of clinical cytopathology was dramatically influenced by the wide implementation of informatics and computer sciences into the laboratory workflow. New types of cameras and microscopes connected to computers made possible image capture and transmission (telecytology). Remote cytological diagnosis can nowadays be achieved either with the use of cytological pictures viewed in real-time from the microscope (dynamic telecytological systems) or with the use of cytological pictures that are first captured in a digital format and then transmitted using a store-and-forward approach to distant observers (static telecytological systems). ISO 15189:2012 for medical laboratories requires successful participation in proficiency testing programs. This article emphasizes on the feasibility of using static telecytological applications in order to implement a proficiency test for cytopathology labs wishing to be accredited according to ISO 15189:2012.

Published: March 2021

Despite the fact that breastfeeding remains the healthiest, simplest and least expensive means of meeting the nutritional needs of newborns and infants, the knowledge and practice as recommended by WHO remain low in most low-and middle-income countries. This study aims at exploring the gap in the knowledge of exclusive breastfeeding among mothers in Northern Nigeria as well as comparing their practises with the WHO recommendations. This was a cross-sectional facility-based study among 343 mothers in Abuja, Northern Nigeria. Data was collected over 8 weeks using a structured interviewer-administered questionnaire assessing knowledge and practise of breastfeeding based on the WHO recommendations. Data collected were analyzed using SPSS version 22. Chi square test of statistical significance was used to measure the degree of bivariate associations at a level of p < 0.05. Only 42.6% of the mothers had good general knowledge of breastfeeding. Exclusive breastfeeding for 6 months was practised by 232 (75.1%) mothers. Having more than one child was associated with good knowledge of breastfeeding (χ2 = 7.331, p = 0.007) while having poor knowledge of breastfeeding (χ2=5.722, p=0.017) was associated with exclusive breastfeeding practise. Commonest reasons for not practising exclusive breastfeeding were insufficient breast milk (38.7%) and resumption of work (19.8%). In this study, the practise of initiating breastfeeding within an hour after birth and exclusive breastfeeding are both in line with WHO recommendations. Continuous breastfeeding awareness campaigns are needed to improve knowledge and sustain the practise of exclusive breastfeeding.>

Published: March 2021

Il progetto consiste nella creazione di un opuscolo informativo, all’interno del quale sono spiegate le principali informazioni relative la gestione del paziente portatore di Lesioni da Pressione. Le nozioni espresse sono alla base del percorso terapeutico, in quando sono indirizzate a lettori non esperti nel campo delle medicazioni difficili. Viste le esigenze del pubblico di assistere a questa tipologia di pazienti, in molti casi in maniera autonoma per quanto riguarda la medicazione vera e proprio, si è ritenuto necessario fornire del materiale per aumentare le conoscenze dei caregiver informali. Lo scopo ultimo è proprio quello di fornire un metodo semplice e sicuro di apprendimento per i cittadini che si occupano della gestione del paziente e delle relative medicazioni; considerando sempre un affiancamento da parte di professionisti. Gli obiettivi che ci si pone con il progetto sono: valutare e visualizzare quelli che sono gli aspetti importanti per i soggetti aventi Lesioni da Pressione, questo comprende la definizione, prevenzione, classificazione e trattamento; l’importanza della continuità assistenziale per questa tipologia di paziente; informare il cittadino su cosa sono le lesioni da pressione (quali sono le accortezze quotidiane da dover attuare per evitare il peggioramento o lo stallo della condizione) ed infine il trattamento vero e proprio tramite l’insegnamento delle medicazioni difficili e della loro applicazione in base ai diversi casi (essendo un argomento vasto e materia di specializzazione in ambito infermieristico si tratterà in maniera semplificata in modo da dare informazioni basilari ma utili). Per la creazione dell’opuscolo è stata effettuata una revisione della letteratura che vede la consultazione di due linee guida, undici articoli e due testi.

Characterization of barium ferrite samples submitted by Ferrox Iron Limited, Prescott, Ontario
Authors: Wheat T A , Hanson A J
Published: March 2021

Surface area and particle size and shape data were obtained for six samples of barium ferrite in an attempt to characterize and hence distinguish each material. The variation in specific surface from 1.2 to 1.8 m²/g was not greatly outside the resolution of
the equipment and hence any distinction drawn between the samples on this basis would be uncertain. All samples exhibited both spherical and chain-like aggregates which were composed of 1 to 2-um crystals which had a slightly platey habit with an irregular outline. No significant morphological
differences were found between the various samples. Although a successful examination of randomly oriented material was achieved using a scanning electron microscope, it was found impossible to examine polarized preferentially oriented material under the same conditions. It was shown that the
extraneous, but coherent, magnetic field introduced into the instrument by the oriented material was sufficient to disturb the electron optics and prevent adequate focus being obtained.
Corrosion of malleable iron bolts in underground service in pipe joints used by the city of Ottawa
Authors: Garrison J G , Biefer G J
Published: March 2021

Malleable iron bolts, used in clamping mechanical joints of underground cast iron water pipes, failed in the threaded portion because of intense corrosion attack. An examination of the bolts showed the malleable iron to be normal in microstructure and chemical
composition. According to the literature, such corrosion failures have been quite common, and are galvanic in nature, because such bolts become anodic relative to the cast iron pipe, which serves as a cathode of relatively large area. It was pointed out that this type of corrosion attack could be
minimized or possibly eliminated by selecting a bolt material conforming to CSA Standard B-131.10-1967. Such bolting is alloyed with copper, nickel, or chromium; in underground service, it would be expected to exhibit a corrosion potential more noble than that of the pipe. This would convert the
pipe into an anode of large area, a much more favourable situation than that experienced by the pipe joint investigated.

A preliminary evaluation of an alternate test to determine the suitability of asbestos fibre in asbestos cement
Authors: Winer A
Published: March 2021

Loose-density test results, when adjusted, have been found by Lake Asbestos of Canada to correlate with results from the strength unit test but there are some discrepancies in this relationship. Since specific surface is related to the packing of the fibre and
since this may be -related to loose density, it seemed appropriate to investigate this relationship. Specific surface was measured by means of gas adsorption and permeability techniques. There appears to be a relationship between specific surface, as measured by gas adsorption, and strength unit.
This relationship is in two directions, i.e., between grades and groups. Also, this relationship appears to be strengthened when specific surface, derived from permeability measurements are used. Because of variations which are to be expected in sampling and strength-unit testing of asbestos, a much
larger number of samples would have to be checked to verify the relation between strength units and specific surface. The number of samples required can be determined statistically from the data and from experience gained in the plant.

Authors: Dixon C F , Spence N S
Published: March 2021

The effect of from 0 to 15% cold reduction on the microstructure, hardness, and magnetic permeability of Sherritt Gordon's SGM nickel strip was investigated. No change in the equiaxed grain structure of the strip was observed as a result of the cold
reduction, but there was a decrease in magnetic permeability that appeared to be directly related to an increase in hardness. Different starting and finishing gauges had no effect on the hardness or magnetic permeability.
Screening tests of the environmental cracking susceptibility of three high-strength structural steels
Authors: Biefer G J , Garrison J G
Published: March 2021

Using the rising-load cantilever test, screening tests of the environmental cracking (EC) susceptibility in 3.5% NaCl solution were performed on three steels (T-1, CHT-100,and a copper-nickel)with tensile . strengths in the range 115 to 135 kpsi. The results
of the tests indicated only a very slight susceptibility to EC under free-corrosion conditions. Under cathodic protection at zinc potentials, however, EC susceptibility was more definite, and caused a degradation of about 20% in the nominal stress intensities at fracture K*, as compared with
values obtained under dry conditions.

Cavitation erosion of a water pump suction bell
Authors: Ashton M C , Magny J G
Published: March 2021

The damage sustained by the suction bell of a vertical water pump has been attributed to cavitation erosion. A consideration of the flow characteristics in the suction bell supports this conclusion. The presence of ferrite and graphite in the cast iron
microstructure of the suction bell increases its susceptibility to this type of attack. Recommendations regarding alternative materials with greater resistance to cavitation erosion have been made.

Phase equilibria and matte solidification in the ternary system ZnS-FeS-Pbs
Authors: Kerby R C
Published: March 2021

Phase equilibria were determined for the simple eutectic systems FeS-ZnS, FeS-PbS and ZnS-PbS which bound the ZnS-FeS-PbS ternary phase diagram. Eutectic points were found at 6 mol % FeS - 94 mol % ZnS and 1135°C, 48 mol % PbS - 52 mol % FeS
and 835°C. and 78 mol % PbS - 22 mol % ZnS and 988°C. The matte solidication studies in the systems FeS-ZnS and FeS-PbS indicated that grain size increased substantially (from 1 micron to 20 microns) as the rates of cooling of the mattes were decreased from 20°C/min to
0.5°C/min.
Rock anchors in mining a guide for their utilization and installation
Authors: Coates D F , Sage R
Published: March 2021

Rock anchors have been used for some time in civil engineering works and in some mining applications. It is expected that their use in mining will become more common. This report provides a summary of fabrication and installation procedures to guide engineers on
mining properties. Selection of anchor types must be related to the mine. However, total system costs analyses have indicated certain good engineering practices. For example, it is usually more cost-effective to use high-strength, new steel cables than second-hand hoist cable (consider the dominant
drilling and installation costs plus the higher capacity). Also there is much to recommend in most cases the use of one grouting for the full length, possibly with sleeves or grease above the anchorage and possibly with mechanical assistance at the anchorage. Installation of anchors in percussion
drilled holes is advantageous owing to the rough surface for bonding. The actual lengths of holes should be known, and caving and water zones should be grouted. Deviations in straightness should be less than 3 in. in 20 ft. Although manual installation must be used, a mechanical method for the
larger anchors would be valuable. During tensioning, a careful load-deformation record should be obtained, including the decrease in deformation on release of the jack load. Safety precautions are particularly important when applying large loads. Correcting undesirable situations can be time
consuming if the experience of others is not available. For example, inability to insert the anchor for the full length of the hole may either require redrilling of the bottom of the hole, acceptance of the situation or redesign of the system. An unexpected load-deformation curve obtained during
tensioning can arise from a change in the jack calibration, slippage at the anchor and other less frequent causes. Failure of the grips during tensioning and failure to release afterwards are not uncommon. Monitoring may either confirm that the anchors are working as expected or indicate the need
for additional support. Measuring anchor loads and rock deformation are the two most practical types of measurements.
An evaluation of four residual fuel-oil additives phase 1 - Nalco Project
Authors: Lee G K , Brown T D
Published: March 2021

Four fuel-oil additives were blended with No. 6 oil and burned in a pilot-scale research boiler under controlled combustion conditions to determine their effect on reducing fireside deposits and corrosion due to vanadium and sulphur in the fuel ash.
High-temperature slagging and corrosion of metal surfaces at 1050 °F were evaluated by metallographic examinations of tube specimens and by analyzing the physico-chemical characteristics of the slag deposits. Low-temperature corrosion was assessed by correlating the weight loss of mild steel
corrosion specimens at 250 ° F with sulphur trioxide in flue gas and the rate of acid build-up on a dew-point probe. Although all four additives contained magnesium in combination with other elements, only one formulation effectively suppressed the deleterious effects of both the molten
vanadium complexes and condensed sulphuric acid. This formulation contained partially dehydrated hydroxides of magnesium and aluminium having a high physico-chemical reactivity. The inclusion of manganese with magnesium in the other three additive formulations did not produce the desired
effect.
The Oil Heating Association of Canada Clean Air Program phase IV: evaluation of burners with high and low speed motors in a domestic hot-water boiler
Authors: Brown T D
Published: March 2021

Operation of six yellow flame burners at different firing rates (0.5, 0.75 and 1.00 US gph) in a domestic hot water boiler equipped with a refractory combustion chamber showed that several of the burner firing rate combinations tested (10 out of 18) could not
meet a combined standard of excess-air below sixty per cent and a smoke number below one. Only one burner could meet the standard at ail firing rates. The burners were generally least efficient and most susceptible to draft at the lowest firing rate. The incorporation of a slip clutch resulted in a
lower smoke index and peak carbon monoxide concentration during start-up and shut-down in 80% of the combinations tested. The performance data confirms the conclusions from previous phases of the program that all burners are least satisfactory at the minimum firing rate.
The Oil Heating Association of Canada Clean Air Program phase V: evaluation of burners with high and low speed motors in a domestic hot water heater
Authors: Brown T D
Published: March 2021

Operation of six test burners in the refractory lined combustion chamber of a domestic hot water heater showed that a burner capable of achieving a smoke number below one at all firing rates would do so at an excess-air level below sixty per cent
(CO?>9%). Only the three burners which were equipped with retention heads could meet this smoke number requirement. The relative changes in mass flow due to changes in the chimney draft were greatest with these same retention head burners although the absolute magnitude of the changes
was essentially constant for all burners when operated at the same firing rate. The recovery rate of the furnace was largely independent of the burner used but was strongly dependent on firing rate and moderately dependent on the minimum excess-air level that the burner could achieve without smoke
production. The incorporation of a slip clutch produced significant reductions in both start-up and shut-down emissions of smoke and carbon monoxide. The minimum smoke emissions were associated with burners with high speed motors.

Cyanidation tests on flotation concentrates of dorrclone sands from Dome Mines Limited, South Porcupine, Ontario
Authors: Kinasevich R S
Published: March 2021

A series of tests, in which different grinding and cyanidation times were used, was performed on samples of flotation concentrate of Dorrclone sands from Dome Mines Limited, South Porcupine, Ontario. A gold extraction of 23.1% was first obtained on a sample
which had been cyanided for 72 hr, but which had not been previously ground. The highest extraction of gold obtained was 46.2%, at a grind of 86.2% -325 mesh, and 72 hr of cyanidation. However, the reagent consumption and reducing power corresponding to this value of gold extraction were
very high. These values are listed below: Reducing power - cc N/10 KMnO?/1 1580 NaCN consumed - lb/ton of ore - 11.9
CaO Consumed - lb/ton of ore - 27.6 In general, it is considered that straight grinding and
cyanidation were not sufficient to yield economic recoveries of gold.

no 8 et C6ryge1) destinée à servir à la préparation du béton de l'entreprise no 5 de la.Manicouagan. L'examen visuel n'a pas permis de déceler de dommage sur les échantillons de beton soumis à-513 cycles de gel et de dégel. Les mesures de la vitesse
dés pulsations périodiques ont indiqué que, des deux bétons, qui sont par ailleurs identiques, celui qui est préparé à laide de Cérygel a fait preuve d'une durabilité legérement supérieure à celle du béton préparé a l'aide de
la Pozzolithe no 8. L'echantillon expérimental de vérification qui contenait de la Pozzolithe a démontré une résistance à Ia flexion et à la compression légèrement supérieure à celle du béton qui contenait du
Cérygel.

Cette expertise a été faite pour déterminer la valeur d'un nouveau procédé de tamisage qui sert à. déterminer la finesse de monture des ciments. Vingt échantillons de 50 g de ciment Portland ont servi à déterminer
la finesse à. l'aide d'un nouveau tamis Alpine à. jet d'air. La finesse de vingt échantillons témoins de 50 g avait été établie par tamisage à la main à. l'aide d'un tamis n° 200 recommandé dans le CSA standard A5-1961. Les résultats des
essais comparatifs indiquent que le tamis h jet d'air donne des résultats plus facilement reproduisibles que le procédé classique CSA, les coefficients de variation pour les deux procédés étant de 2.8 et de 6.8 p. 100 respectivement. De plus, on croit que le degré
de reproductibilité des résultats des essais au tamis à jet d'air devrait etre du meme ordre que celui que l'on obtient avec le procédé de la perméabilimétrie à. l'air de Blaine qui sert à déterminer la surface spécifique des
ciments.

Published: March 2021

Insulin Resistance syndromes (IR's), are a group of genetic disorders caused due a functional defect in chromosome 19p13. It is an autosomal recessive condition. Donohue Syndrome was initially described by Donohue and Uchida in 1948 and 1954, a case of sisters born to parents with a first-degree consanguineous marriage. Infants presented with typical facial features that resembled the Leprechaun elves of Irish fairy tales. The following is a report of a rare case of dental complications of Severe Insulin Resistance Syndrome. An eight year old female child, with characteristic features of severe insulin resistance syndrome, reported to the Department of Pediatric and Preventive Dentistry, Pravara Institute of Medical Sciences, Loni, presenting with cariously destructed molars and a previous history of dental treatment under local anaesthesia. Given her condition, it was decided to reduce the multiple appointments, to one appointment with all procedures done under general anaesthesia. The following case report discusses the advantages, disadvantages and post operative complications faced when forming a treatment strategy for Severe Insulin Resistance Syndrome.

Humans require treatment due to the loss of tissues after trauma and diseases. Tissue engineering is a growing field of engineering and medical science to restore, maintain, or improve function of damaged or diseased tissues. The use of three-dimension (3D) scaffolds in particular offers a potential option for patients with tissue deficiency. Polylactic acid (PLA), poly-caprolactone (PCL), polyether-ether-ketone (PEEK), and thermoplastic polyurethane (TPU) are biomaterials that are commonly used in tissue engineering. Their applications of pure material or composite and supportive materials are of great importance for clinical practices. This review provides information on biomaterials and major areas of application and discusses their advantages and disadvantages against each other. The literature search from the database PubMed was done for the key words 3D PLA, PCL, PEEK, and TPU separately and 2029 articles were identified. These articles were limited according to clinical, in vivo and observational studies published in English and 140 articles were evaluated for this review. We selected the main articles according to the current data of 3D scaffolds and identical articles were removed. Fifty articles were included in the review. Many studies have reported the advantages of 3D scaffolds with composite or supplement materials over pure materials in the medical treatment. The advances in the development of new 3D scaffolds hold great promise for the prospective applications in the medical treatment.
Expanding Opportunities for American Descendants of Slavery to Build a More Inclusive and Diverse Global Health Workforce
Authors: Okegbe Tishina
Published: March 2021

Historically, the terms African American and Black have been used interchangeably to describe any person with African ancestry living in the United States. However, Black Americans are not a monolith, and legitimate differences exist between those with generational roots in the United States and either African or Caribbean immigrants. American descendants of slavery (ADOS) are underrepresented in many fields, but I have noticed during my decades long career in global health that they are acutely absent in this field. Here, I offer seven recommendations to improve recruitment, retention, and advancement of ADOS in the global health field. Immediate implementation of these recommendations will not only bring diverse perspectives and immense capacity to the field but also allow ADOS an opportunity to engage in compelling and meaningful work and to collaborate with those from their ancestral homelands.

Antimicrobial resistance has become a global health problem. Although a wide range of chemotherapeutic antimicrobials are available for treatment of microbial related infections and diseases, development of resistance to these chemotherapeutic agents is rapidly on the increase. Extracts from some plants have shown some promise in antimicrobial activity. This has led to the screening of several medicinal plants for their potential antimicrobial activity. Therefore, this study was aimed at evaluating the antimicrobial effect of ethanolic and aqueous extracts of Garcinia kola against Klebsiella pneumonia and Candida albicans in vitro. The Garcinia kola seeds extracts were obtained using 70% ethanol and distilled water respectively. Phytochemical screening of Garcinia kola revealed the presence of various potent phytochemicals such as tannins, saponins, flavonoids, alkaloids and glycosides. Both extracts of the seeds were investigated for antimicrobial activity using disc diffusion and agar well diffusion sensitivity tests. The ethanol extract produced zones of inhibition of about 7.3 mm for Candida albicans only at a concentration of 800mg/ml for the disc diffusion test. For the agar well diffusion test, the aqueous extract produced zones of inhibition of about 9.5 mm, while the ethanol extract produced zone of inhibition of 19 mm against Candida albicans at a concentration of 800 mg/ml. However, at the same concentration, the ethanol extract produced zones of inhibition of about 8.5 mm against Klebsiella pneumoniae. The findings of this study revealed that Garcinia kola was not effective in treating Klebsiella pneumonia infections but has potential in treating Candida albicans infections.

Technological progress, non-price factors competitiveness, and changes in trade income elasticities: empirical evidence from South Korea and Hong Kong*
Authors: Resende Marco Flávio Cunha , Leone Vitor , Torres Daniela Almeida Raposo , Coleman Simeon
Published: March 2021

In the balance-of-payments-constrained growth model literature, income elasticities (IEs) are considered as the crucial element determining a country's long-run growth rate. Although the extant literature accepts that technology matters for IEs magnitude, explanations linking technology and IEs magnitude are limited. In this paper, we make use of the National Innovation System (NIS) concept from the Evolutionary School to explain the channels through which the size of a country's IEs is influenced by the level of development of its NIS, which in turn is a channel through which the non-price competitiveness factors work. Additionally, we empirically test the hypothesis that the catch-up allowed by NIS developments achieved in South Korea and Hong Kong improved their IEs over the 1980–1995 period. Our empirical results suggest a link between the level of NIS development and the size of the IEs.

Putting Civil Society in Its Place
Authors: Jessop Bob
Published: March 2021

Renowned social and political theorist Bob Jessop explores the idea of civil society as a mode of governance in this bold challenge to current thinking. Developing theories of governance failure and metagovernance, the book analyses the limits and failures of economic and social policy in various styles of governance. Reviewing the principles of self-emancipation and self-responsibilisation it considers the struggle to integrate civil society into governance, and the power of social networks and solidarity within civil society. With case studies of mobilisations to tackle economic and social problems, this is a comprehensive review of the factors that influence their success and identifies lessons for future social innovation.
