Population Characteristics of the Limpet Patella caerulea (Linnaeus, 1758) in Eastern Mediterranean (Central Greece)
Authors: Vafidis Dimitris , Drosou Irini , Dimitriou Kostantina , Klaoudatos Dimitris
Published: April 2020

Limpets are pivotal for structuring and regulating the ecological balance of littoral communities and are widely collected for human consumption and as fishing bait. Limpets of the species Patella caerulea were collected between April 2016 and April 2017 from two sites, and two samplings per each site with varying degree of exposure to wave action and anthropogenic pressure, in Eastern Mediterranean (Pagasitikos Gulf, Central Greece). This study addresses a knowledge gap on population characteristics of P. caerulea populations in Eastern Mediterranean, assesses population structure, allometric relationships, and reproductive status. Morphometric characteristics exhibited spatio-temporal variation. Population density was significantly higher at the exposed site. Spatial relationship between members of the population exhibited clumped pattern of dispersion during spring. Broadcast spawning of the population occurred during summer. Seven dominant age groups were identified, with the dominant cohort in the third-year class. Significant negative allometric relationships were exhibited between morphometric characteristics. Differences in growth patterns among populations were indicated.

Published: April 2020

Reducing water use could impact existing sewer systems but this is not currently well understood. This work describes a new flow and wastewater quality model developed to investigate this impact. SIMDEUM WW® was used to generate stochastic appliance-specific discharge profiles for wastewater flow and concentration, which were fed into InfoWorks® ICM to quantify the impacts within the sewer network. The model was validated using measured field data from a sewer system in Amsterdam serving 418 households. Wastewater concentrations of total suspended solids (TSS), chemical oxygen demand (COD), total Kjeldahl nitrogen (TKN) and total phosphorus (TPH) were sampled on an hourly basis, for one week. The results obtained showed that the InfoWorks® model predicted the mass flow of pollutants well (R-values 0.69, 0.72 and 0.75 for COD, TKN and TPH respectively) but, due to the current lack of a time-varying solids transport model within InfoWorks®, the prediction for wastewater concentration parameters was less reliable. Still, the model was deemed capable of analysing the effects of three water conservation strategies (greywater reuse, rainwater harvesting and water-saving appliances) on flow, nutrient concentrations, and temperature in sewer networks. Results show through a 62% reduction in sewer flow, COD, TKN and TPH concentrations increased by up to 111%, 84% and 75% respectively, offering more favourable conditions for nutrient recovery.
Les contraintes et difficultés des observations sur les glaciers de montagne
Authors: Six Delphine , Vincent Christina
Published: April 2020

L’évolution des glaciers est l’un des indicateurs choisis par le groupe IPCC (le Groupe d’experts intergouvernemental sur l’évolution du climat) pour évaluer la variabilité climatique et la tendance au cours des dernières décennies. Les glaciers sont considérés comme un indicateur majeur du passé et du futur, tant dans les régions soumises aux activités humaines que dans les régions éloignées, à de hautes latitudes, où aucune mesure météorologique conventionnelle n’existe. L’évaluation de la déglaciation en montagne en réponse au changement climatique sur de longues périodes de temps est crucial non seulement pour évaluer les impacts sur les ressources en eau, mais aussi pour évaluer leurs contributions à la hausse de niveau des océans, et pour prévoir les risques naturels liés aux évolutions des glaciers. Les mesures glaciologiques et météorologiques sont toujours un défi dans ces zones climatiques complexes. Dans ce contexte, «le Service National d’Observation » GLACIOCLIM (SNO) suit à long terme différents sites dans le monde entier (Alpes, Andes, Himalaya, Antarctique) par des mesures glaciologiques (bilan de masse, paramètres topographiques) et des mesures météorologiques combinant observations in-situ et télédétection (https :// glacioclim. osug. fr).
Suivi en continu des températures et conductivités des eaux thermales en contexte hyper minéralisé. Salins-Les-Thermes, Savoie
Authors: Malet Emmanuel , Dzikowski Marc , Fanget Bernard , Doublet Camille , Gasquet Dominique
Published: April 2020

La spécificité des eaux thermales de Salins-les-thermes et l’aménagement du site perturbent l’acquisition des suivis en continu de la température et de la conductivité électrique des eaux. L’accessibilité aux dispositifs de mesures étant limitée durant une période de l’année, ces derniers enregistrent les perturbations attribuées au colmatage des sondes par des oxydes de fer et probablement au dégazage de CO2. Les perturbations se traduisent par un phénomène d’oscillation à haute fréquence de mesures et une dérive plus ou moins marquée en fonction des types de sondes et de leur positionnement.

Published: April 2020

Les karsts de Patagonie (archipel de Madre de Dios, Chili, 50° S) comptent parmi les plus arrosés de la planète (> 8 000 mm/ an). À partir de socles d’erratiques glaciaires, de dykes exhumés ou de peintures historiques, les taux de dissolution superficielle sur karst nu sont estimés supérieurs à 100 mm/ millénaire. Nous avons instrumenté un bassin-versant sur lapiés nu ; le suivi de paramètres météorologiques (précipitation, température, vitesse et direction du vent) et de paramètres de ruissellement dans les rigoles (débit, conductivité, température) permet d’affiner la connaissance de l’écoulement sur calcaire en contexte océanique subpolaire. Le vent, les embruns et surtout le régime des précipitations contrôlent les modalités de la dissolution des calcaires en surface. Un relevé topographique fin permet de montrer une organisation du drainage en marches d’escalier dont la genèse et l’évolution semblent conditionner un fonctionnement en « step-pool system » se traduisant notamment par une forte variabilité des débits durant l’onde de crue.

Published: April 2020

Since 2011 a dense network of measurements has been installed on the karst system of Les Fonts (into and outside this system). This network combines measurements of water level and water temperature on 4 stations into the karst and 6 on rivers (with a spring). The acquisition frequency varies from 5 to 30 minutes in according to hydrological period. The database validated the conceptual scheme of the karst system. In addition some hydrological phenomena have been showed (e. g. variation of water temperature during floods). This is the combined effect of the sensor density and the high acquisition frequency that allowed the acquisition of these results. The main objective (for the next 5 years) is to keep operational this network despite (i) the difficulties for accessing to sites (water level in caves, level of CO2…) (ii) without funding dedicated and (iii) with the experimental difficulties linked to the treatment, critical and storage of data. In perspective, this research network could become an operational network for those local authorities improve them qualitative and quantitative water resource management.
Instrumentation et analyse de l’érosion régressive en rivière souterraine. Le projet participatif Bilborupt et la zone des cascades du Rupt du Puits, Lorraine, France
Authors: Jaillet Stéphane , Herbillon Claude
Published: April 2020

The profile of underground rivers, like surface rivers, present sometimes the upstream part of a headward erosion wave. In order to study this area with very active morphogenesis, an original instrumentation was put in place in the zone of the «cascades du Rupt du Puits » (Lorraine, France). Fuzboll balls are stepped to constitute a device called “ bilborupt”. These are arranged in 11 successive points and surrounded the zone of the waterfalls. Cavers visiting the cavity are invited to carry out the survey themselves. 39 surveys are analyzed and show the variability of water levels, but also the hydraulic slopes along the 4 waterfalls studied. The results show a decrease of the hydraulic slopes downstream as well as during the increase of the flows. The hydraulic front, which is to say the area where slopes and speeds are maximal, move downstream. This is in agreement with the morphological analysis of the waterfalls zone.

Authors: Nastyuk Vasyl , Mikhailov Oleksandr , Izbash Ekaterina , Kondratenko Vitalii
Published: April 2020

The purpose of the article is to investigate the peculiarities of judicial control during investigative (search) actions that require prior permission on the basis of the analysis of legislation and modern theoretical concepts of the science of criminal process. Special research methods were also used in the work, in particular, comparative legal; special legal, logical-legal and systematic.
The article is devoted to specific issues of judicial control, which, in accordance with the current legislation of Ukraine, is carried out when granting permission for investigative (search) actions that require it. The investigative (search) actions that require the prior permission of the investigating judge are identified. The norms of the international and national legislation are analyzed, which enshrines guarantees from illegal entry into the dwelling or other property of a person and carrying out of procedural actions there. Attention is drawn to the need for a clear delineation of investigative (search) actions, such as inspection and house search or other property of a person, since their substitution will lead to the court finding the evidence inadmissible. The position of the European Court of Human Rights on the criteria for the lawfulness of the search is outlined. Emphasis is placed on the specifics of conducting a house search or other property of a lawyer. It is concluded that the effective provision by the investigating judge of the rights, freedoms and interests of persons whose housing or other property is planned to be searched is a necessary condition for the realization of the principles of criminal proceedings.

Authors: Vozniuk Andrii , Dudorov Olexandr , Tytko Anna , Movchan Roman
Published: April 2020

Article presents comparative analysis of features and characteristics of organized criminal associations recommended for further criminalization by provisions of Palermo Convention and Framework Decision 2008/841/JHA. Certain peculiarities of the abovementioned provisions implementation in more than 50 states (Asia, America and Europe) have been outlined.

We expressed and proved the hypothesis stating that criminalization of actions performed by the members of organized groups and criminal organizations by different states separately is partly explained with consideration of different international legal acts by national legislators: Palermo Convention and Framework Decision 2008/841/JHA.

On the basis of analysis of key global models used to criminalize the socially dangerous actions with aim to counteract the organized crimes (collusion, participation, entrepreneurship, marking/registration) we justified the following opinion: 1) within the limits of criminal associations countering collusion and participation models are considered to be the most efficient; 2) use of entrepreneurship model allows to justify the need for establishment of responsibility for legal entities involved in criminal associations functioning or utilization of relevant criminal measures; 3) registration/marking model may be efficient for counteracting the extended terrorist organizations.

Published: April 2020

The article considers the problem of the functionality of existing bankruptcy forecasting models for the pharmaceutical industry, the significance of which is due to the strategic role of this industry in ensuring drug safety in Russia. In conditions of import dependence, it is possible to increase the competitiveness of domestic enterprises by investing in it, which actualizes the task of increasing their investment attractiveness, one of the main elements of which is long-term and predictable financial stability. The study shows that today the assessment of financial stability and the likelihood of bankruptcy is possible only on the basis of generalized models of domestic and foreign authors, which in general give ineffective results. This is due to the fact that standard models do not take into account the industry specifics of the enterprises in question, and therefore are not able to reliably determine the presence or absence of a threat of insolvency. An important direction in the development of the pharmaceutical industry of the Russian Federation in the current environment is the search for effective tools for economic analysis and the development of the correct adapted methodology for predicting the probability of bankruptcy.

Published: April 2020

The relevance of the article due to the need for the legal regulation of relations regarding the use of cloud computing that have already involved in the most important areas of public life. Currently (along with the undeniable benefits), there are many problems caused by the use of cloud technologies. The current legislation needs to be modified to create a regulatory platform, remedies, and factors to prevent or prevent illegal activity. The authors of this article have used various methods of scientific research, namely the analysis, synthesis, analogy, deduction, induction, formal-legal, comparative-legal, interpretation of law, etc. The study shows that there is currently no legal regulation in Ukraine on the use of cloud technology. Today, it is possible to distinguish several ways of legal regulation of relations on the use of cloud technologies: 1) legal regulation of these relations can be done using already existing regulatory acts; 2) amend the existing legal framework (adaptation of stable legal norms to the new information reality); 3) to create new legal acts on the regulation of exclusive relations related to the use of cloud technologies, taking into account their specifics.

Published: April 2020

The aim of the article is to analyze current trends in the development of cyber insurance. The following methods of scientific research were used in the preparation of the article: generalization, correlation analysis, comparative analysis. The authors analyze in detail the main trends in the spread of cybercrime. The correlation analysis between the number of registered cybercrimes in a particular country and its GDP, the number of business entities, indicated the lack of correlation between the studied indicators. It states that the most common types of cybercrime are: hacking, unauthorized access, accidental exposure, insider and physical theft. The sectoral analysis of the distribution of cybercrime has revealed a decrease in the share of financial companies while increasing the share of health care companies. It is noted that cyber insurance is one of the effective preventive measures that minimize the negative effects of cybercrime intervention. The article presents segmentation of the cyber insurance market by geography and size of insurance companies. The results of the analysis showed the dominance of US companies in the cyber insurance market. It is stated that the sectoral distribution of cybersecurity policy purchasers in general follows the trends of the sectoral distribution of cybercrime. The volume of cyber insurance, expenses of insured legal entities is analyzed. The main trends in the development of cyber insurance have been identified. The factors that hold back the development of cyber risk insurance have been identified. The main ones include the following: high level of information entropy in the process of cyber risk assessment, lack of a single standard for filling insurance services in the field of cyber insurance. It is noted that in the medium term the cyber insurance market is prospective for insurance companies. This is caused by the increasing scale of cyber threats and the costs associated with cyberattacks.
Poder, reciprocidad y ordenamiento del cosmos en El Shincal de Quimivil (Catamarca, Argentina)
Authors: Giovannetti Marco , Páez María Cecilia
Published: April 2020

En virtud de la comprensión de las lógicas de ordenamiento andinas, es frecuente la referencia al poder como concepto directriz para comprender la forma de percibir y racionalizar el mundo. Para ello, la ciencia social moderna ha aportado un conjunto de premisas con las cuales poner en discusión este significante, tales como la unidireccionalidad, la asociación positiva entre poder y dominio, su acumulación en la forma de prestigio o la centralidad humana en la toma de decisiones. No obstante, su extrapolación a sociedades con una racionalidad diferente a la occidental no debe ser acrítica. En este trabajo nos proponemos, por un lado, repensar las bases epistemológicas sobre las que se construyen las nociones de poder que se aplican a las sociedades andinas. Para ello apelaremos a las nociones de complementariedad, reciprocidad y comunidad. Por otro, discutiremos el poder como flujo de potencias y pondremos el acento en las wakas en tanto entidades que concentran y gestionan estos flujos, con un agenciamiento que permite trascender la dicotomía entre mundo físico y mundo humano. Anclamos esta propuesta en el estudio de la materialidad del sitio inka El Shincal de Quimivil, que exhibe la presencia de entidades poderosas a través de un esquema ordenado de wakas en tres niveles, incluidos unos en otros, en orden creciente: las rocas, el cerro y el sitio.

Realizing a high luminescence dissymmetry factor (

g

lum

) is a paramount yet challenging issue in the research field of circularly polarized luminescence (CPL). Here, we reported a novel set of organic conjugated systems with twisted intramolecular charge transfer (TICT) characteristics based on conjugated
o
-carborane-binaphthyl dyads composing of binaphthyl units as chiral electron donors and
o
-carborane units as achiral electron acceptors, demonstrating intense CPL with large

g

lum

values. Interestingly, single-crystalline
o
-1 exhibited a high-level brightness and a large

g

lum

factor as high as +0.13, whereas single-crystalline
o
-2 processed a relatively low brightness with a decreased

g

lum

value to -0.04. The significant diversity of CPL-active properties was triggered by the selective introduction of
o
-carborane units onto the binaphthyl units. Benefiting from the large magnetic dipole transition moments in TICT states, the CPL activity of TICT
o
-carborane-based materials exhibited amplified circular polarization. This study provides an efficient molecular engineering strategy for the rational design and development of highly efficient CPL-active materials.
Quantifying the relationship between pollen sedimentation in lakes and land cover using historical maps
Authors: Nielsen Anne Birgitte
Published: April 2020

Pollen records from lake sediments have a great potential for providing information on the quantitative composition of past vegetation and land cover in the surrounding landscape. This can contribute to a better understanding of the development of the cultural landscape and interactions between human impact on the landscape and natural conditions like soil and climate. A good understanding of the history of cultural landscapes is necessary for choosing appropriate management strategies for areas dependent on cultural impact, such as heaths, meadows and dry pastures. It is also important for archaeological research concerning utilisation of the landscape in earlier periods. Furthermore, quantitative reconstructions are relevant for climate research. Here they can be used to test climate models, since model predictions of past climate can be translated into past vegetation, which can then be compared to pollen-based reconstructions. Past vegetation cover is also a necessary input to climate models, as it influences albedo, evapotranspiration and carbon storage and cycling. Quantifying vegetation from fossil pollen samples requires a detailed understanding of the way vegetation is reflected in pollen assemblages, including the approximate size of the area of vegetation represented. The relationship between pollen and vegetation is complicated by the fact that different plant species produce different amounts of pollen, and that pollen types are dispersed differently in the atmosphere, depending on their size, shape and weight. These pressing challenges in pollen analysis have attracted much attention in recent years. Models have been developed to describe and simulate species specific pollen dispersal, to quantitatively relate pollen proportions to plant abundance, as well as estimate pollen productivity and to quantify the pollen source area of different types of basins (Parsons & Prentice 1981; Prentice & Parsons 1983; Prentice 1985; Sugita 1993, 1994; Sugita et al. 1997, 1999; Broström 2002; Bunting et al. 2004). The Geological Survey of Denmark and Greenland (GEUS) has in recent years contributed to the development and validation of such models through the project AGRAR 2000 (Odgaard 1999; Nielsen 2003), where quantitative estimates of past land cover in different regions of Denmark were one of the main objectives, and through participation in the international research network POLLANDCAL (POLlen LANdscape CALibration), funded by NORDFORSK (Nordic Research Board), which focuses on further model development, validation and application.
Taxonomic note: speciation within the operational group Bacillus amyloliquefaciens based on comparative phylogenies of housekeeping genes
Authors: Ngalimat Mohamad Syazwan , Sabri Suriana
Published: April 2020

Many of the publically available Bacillus 16S rRNA genes and genomes in the NCBI database are inconsistently assigned as B. amyloliquefaciens. The highly conserved nature of the 16S rRNA gene makes it fail to differentiate species within the operational group B. amyloliquefaciens. Here, comparative phylogenies of the complete 16S rRNA, gyrB, rpoB, trpB, recA, and cheA nucleotide sequences of bacterial strains within the operational group were analyzed. As the result, the gyrB, rpoB, and trpB phylogenetic analyses showed stable topology that comprised three monophyletic clades: (i) B. amyloliquefaciens; (ii) B. siamensis; and (iii) B. velezensis. Phylogenies derived by comparison of the gyrB, rpoB, trpB, recA, and cheA with the 16S rRNA gene-derived phylogeny was significant as evaluated by the likelihood ratio test. The trpB, rpoB, and trpB gene-derived phylogenies provide a tool for speciation within the operational group B. amyloliquefaciens.

Infestations Myxobolus sp. in Gills Koi (Cyprinus carpio) That No Clinical Symptoms
Authors: Zulkifli  , Novia Christi Prihartini
Published: April 2020

Ornamental fish trade between regions in Indonesia allows the transfer of disease, especially if the disease does not show clinical symptoms in fish traded. Koi fish in Tahuna, North Sulawesi, mostly come from the area of ​​East Java, which is one area with many cases of myxobolusis. In addition, the potential for parasitic diseases that come along when koi fish are brought between areas cannot be avoided, because the examination of parasites, especially Myxobolus sp. no longer listed in the regulation as a quarantine inspection requirement. The purpose of this study was to see the Myxobolus sp infestation that infected koi in Tahuna, North Sulawesi, although there were no clinical symptoms using conventional techniques and histopathology. The results of the examination showed Myxobolus spore infestation on the gills of the koi, although the amount was not much, both conventional and histopathological techniques. This shows that our level of awareness of the types of parasites that can infect fish is still lacking. Myxobolus sp is only transmitted through the spore stage back and forth; there is no horizontal or vertical transmission in fish or tubifex T worm populations. More knowledge regarding the life cycle of the Myxobolus sp. in order to obtain the right handling to deal with outbreaks, especially water quality management at the location of the cultivation.
Discrete game problem with ring-shaped terminal set
Authors: Izmest'ev I.V.
Published: April 2020

In a normed space of finite dimension a discrete game problem with fixed duration is considered. The terminal set is determined by the condition that the norm of the phase vector belongs to a segment with positive ends. In this paper, a set defined by this condition is called a ring. The aim of the first player is to lead a phase vector to the terminal set at fixed time. The aim of the second player is the opposite. In this paper, optimal controls of the players are constructed. Computer simulation of the game process is performed. A modification of the original problem, in which at an unknown time there is a change in the dynamics of the first player, is considered.

On totally global solvability of controlled second kind operator equation
Authors: Chernov A.V.
Published: April 2020

We consider the nonlinear evolutionary operator equation of the second kind as follows $\varphi=\mathcal{F}\bigl[f[u]\varphi\bigr]$, $\varphi\in W[0;T]\subset L_q\bigl([0;T];X\bigr)$, with Volterra type operators $\mathcal{F}\colon L_p\bigl([0;\tau];Y\bigr)\to W[0;T]$, $f[u]$: $W[0;T]\to L_p\bigl([0;T];Y\bigr)$ of the general form, a control $u\in\mathcal{D}$ and arbitrary Banach spaces $X$, $Y$. For this equation we prove theorems on solution uniqueness and sufficient conditions for totally (with respect to set $\mathcal{D}$) global solvability. Under natural hypotheses associated with pointwise in $t\in[0;T]$ estimates the conclusion on univalent totally global solvability is made provided global solvability for a comparison system which is some system of functional integral equations (it could be replaced by a system of equations of analogous type, and in some cases, of ordinary differential equations) with respect to unknown functions $[0;T]\to\mathbb{R}$. As an example we establish sufficient conditions of univalent totally global solvability for a controlled nonlinear nonstationary Navier-Stokes system.
Mathematical model of gas hydrate formation of sulfur dioxide by injecting liquid sulfur dioxide into a layer saturated with methane and water
Authors: Khasanov M.K. , Kil'dibaeva S.R.
Published: April 2020

This paper presents the results of a theoretical study for the gas hydrate formation of sulfur dioxide by injecting liquid sulfur dioxide into a layer saturated with water and methane. Self-similar solutions of a straight-line parallel problem are constructed. The dependences of the temperature and the coordinates of the formation front of sulfur dioxide gas hydrate on the layer permeability are explored. It is established that, as the layer permeability increases, the temperature of the phase transition increases on the surface. As a result, at sufficiently large values of layer permeability, the temperature at the hydrate formation border may exceed the equilibrium decomposition temperature of sulfur dioxide gas hydrate, which will correspond to the appearance of an intermediate region saturated with a mixture of water, sulfur dioxide and its gas hydrate in a state of thermodynamic equilibrium. It is established that at sufficiently high values of injection pressure and permeability, the gas hydrate formation of sulfur dioxide will occur in the extended region.

There are quite a number of neurological diseases, which initially present to the ophthalmologists. Based on the proper history and clinical findings ophthalmologist have to suggest the ancillary neuro-imaging to support their provisional diagnosis and reach the site of lesion. Unless the ophthalmologists are aware of the right imaging at right time and at right area to focus, there are many pitfalls. MRI and CT of the brain and orbit are important investigations in neuro-ophthalmology which if intelligently ordered can add to the diagnostic and management process. In general, MRI is the most commonly ordered investigation in neuro-ophthalmology with so many additional sequences as FLAIR, GRE, diffusion weighted imaging, spectroscopy, in addition to T1 and T2 weighted imaging. Having said that CT scan has its advantages in cases of bony pathologies and acute brain hemorrhages.
This article reviews the indications and importance of different neuro-imaging techniques, based on the previous studies from 1997 to 2019.

Purpose:  To assess post-operative cosmetic and functional results of external Dacryocystorhinostomy with Subciliary incision in adults with primary naso lacrimal duct obstruction (NLDO).

Study Design:  Quasi experimental study.

Place and Duration of Study:  Oculoplasty clinic, Al Ibrahim Eye Hospital, Malir, from July 2016 to September 2017.

Material and Methods:  Hundred eyes of hundred patients were included. Inclusion criteria was all the patients between the ages of 20 to 70 years having epiphora with diagnosis of NLDO, chronic Dacryocystitis or Mucocele. Patients having ectropion or entropion of inferior punctum were excluded from the study. DCR with intubation was performed through Sub ciliary incision. Inner canthus was photographed with a Nikon D70S digital camera at 1, 3 and 6 months after surgery. Functional success was determined by subjective improvement in watering and patent drainage passage on syringing. Cosmetic result of the scar was assessed by subjective satisfaction of the patient and grading of the subciliary incision scar according to a four level scale by two ophthalmologists. SPSS version 20.0 was used to analyze the data.

Result:  DCR was done on 100 eyes in 100 patients. Functional and cosmetic success was noted in 90 (90%) eyes. 83 patients attained successful functional outcome, which was confirmed on syringing. On objective grading of the scars by ophthalmologist at the final follow up it was observed that 85 patients had invisible scar. Whereas, 2 had moderately visible scar and 3 patients had minimally visible scar. Subjective grading revealed 85 scars to be invisible, 2 moderately visible and 2 minimally visible.

Conclusion:  Post-operative cosmetic as well as functional results of subciliary incision in external Dacryocystorhinostomy were found to be highly encouraging.

Background: Educational workshops help physicians (MDs) include physical activity and exercise (PAE) content in more patient appointments. It is unclear if MDs with varying degrees of self-confidence discussing PAE with their patients equally benefit from such training. We evaluated whether MDs’ initial self-confidence affects the impact of an educational PAE workshop.
Methods: MDs (n = 63) across Canada completed self-reflection questionnaires initially and 3-months following a PAE workshop. MDs were divided into low-confidence [self-efficacy score (out of 100%): <40%; n = 21], medium-confidence (40-60%; n = 19) and high-confidence (>60%; n = 23).
Results: PAE counselling self-efficacy increased in all groups (relative increase: Low=~40%, Medium=~20%, High=~10%). Training increased the low-confidence group’s knowledge, awareness of guidance/resources and perception of their patients’ interest in lifestyle management (~30% change; all p < 0.001). Compared to baseline, a greater proportion (all p < 0.001) of MDs reported prescribing exercise at 3-month follow-up in each of the low-confidence (10% to 62%) medium-confidence (16% to 89%) and high-confidence (57% to 87%) groups. 
Conclusion: PAE training favorably improved MDs’ self-confidence, perceived impact of many barriers and the proportion of MDs prescribing exercise, at each level of confidence. An educational workshop particularly assisted MDs with low-confidence (i.e., those who needed it the most) integrate PAE into their practice.
