Le four à chaux FR 1430 de Saint-Martin-le-Bas (Gruissan, Aude) : éclairage interdisciplinaire sur la chaufournerie en pays narbonnais aux xie-xiiie siècles
Authors: Vaschalde Christophe , Duperron Guillaume , Doniga Aline
Published: March 2020

La fouille de l’établissement portuaire antique de Saint-Martin-le-Bas à Gruissan (Aude) a mis au jour une importante occupation médiévale, à laquelle est associé un four à chaux daté entre le xie et le début du xiiie siècle. Cette structure étant exceptionnellement bien conservée, un large éventail d’analyses archéométriques a pu être réalisé, qui met en lumière l’organisation du travail des chaufourniers et permet de mieux appréhender le niveau de technicité de leur savoir-faire. Dans un contexte de fort développement de l’usage de la chaux dans le bâtiment, les artisans de Saint-Martin-le-Bas ont su mettre à profit les matières premières récupérées et le combustible issu des boisements de la frange littorale dans un territoire faisant l’objet d’une stratégie de mise en valeur de la part des archevêques de Narbonne.
Renaissance musicale

Published: March 2020

Plusieurs plaques de schiste gravées ont été mises au jour lors de la fouille du couvent des Jacobins de Rennes qui s’est déroulée entre 2011 et 2013. Parmi les noms, les dessins ou les caricatures, une portée musicale a retenu l’attention des archéologues, peu accoutumés à ce genre de découverte. Une soprano spécialisée en chants religieux anciens a donc été sollicitée afin d’approfondir l’analyse de ce témoignage rare daté du XVe siècle. Cette collaboration a permis de décrypter la petite œuvre et d’en proposer une interprétation qui enrichit d’une dimension inhabituelle les nombreux résultats de la fouille (http://www.irisa.fr/immersia/tablette-jacobins/).
An exploratory analysis of noun phrases in civil engineering writing
Authors: Guillerit Margaux
Published: March 2020

Les études récentes en linguistique montrent que les écrits universitaires se caractérisent par des syntagmes nominaux complexes. Cependant, peu d’études concernent la langue de spécialité ; les rares études relatives aux textes en génie civil font état de différences entre la langue des ingénieurs et des étudiants, ces derniers utilisant des phrases plus complexes que les ingénieurs. Toutefois, aucune de ces études ne s’intéresse aux syntagmes nominaux. Dans cet article, nous cherchons donc à déterminer en quoi les syntagmes nominaux dans les textes rédigés par les étudiants diffèrent de ceux écrits par les ingénieurs (en termes de fréquence, de structure et de longueur), et si le registre joue un rôle dans l’utilisation des syntagmes nominaux. Notre article s’appuie sur un corpus de textes écrits par des ingénieurs et des étudiants (comptes rendus et comptes rendus de laboratoire) qui a été analysé selon les méthodes et outils de la linguistique de corpus. Contre toute attente, les résultats montrent que la longueur et la structure des syntagmes nominaux sont similaires dans les textes des ingénieurs et des étudiants. De plus, le registre joue un rôle déterminant dans l’utilisation des syntagmes nominaux parmi les registres étudiants.
Framing Rural France as an African studies laboratory: The Formation à la recherche en Afrique noire (FRAN), 1969-1983
Authors: Sanders Allison
Published: March 2020

This paper examines African studies in France through the case of the Formation à la Recherche en Afrique Noire (FRAN), an interdisciplinary training program which, from 1969 to 1983, used collective fieldwork in rural France as a tool to transmit and study the practice of africanisme. This study of the FRAN, conducted through an analysis of interviews, documentary and archival sources, sheds light on this period in the history of French African studies, as well as the way in which these fieldwork training practices were influenced by the ambiguous relationship between France and her former African colonies.
Les instituts français de recherche dans le marché académique africain anglophone
Authors: Pommerolle Marie-Emmanuelle
Published: March 2020

Cet article s’intéresse à l’insertion des instituts français de recherche en Afrique dans le monde de la recherche en Afrique anglophone, à partir du cas kenyan. Face au développement d’un marché de la recherche guidé par les bailleurs du développement, l’institut propose un modèle de recherche critique et indépendant mais ne répond pas forcément aux attentes des bailleurs, ni de partenaires académiques. Ceux-ci sont en effet attirés par ce marché lucratif, et doivent répondre aux injonctions d’un monde universitaire en croissance, qui exige d’eux davantage d’enseignements mais aussi des résultats de recherche quantifiables. Dans ce contexte, le modèle promu par les IFRE est minoritaire et insuffisamment attractif et pourrait changer d’échelle, en s’européanisant et en développant les projets transcontinentaux, à partir d’un réseau unique qu’il est possible de mobiliser.

LRFM Analysis as a Customer Segmentation Tool in the Tourism Sector
Authors: Özkan Pınar
Published: March 2020

Increasing competition in the tourism industry forces industry professionals to try increasingly harder to develop stronger ties with their customers to increase customer loyalty. Many firms invest heavily in customer relations management (CRM) practices to monitor changes in customer needs so as to be able to offer personalized services, differentiate themselves from competitors, and create competitive advantage. RFM is a popular CRM technique used to effectively classify large amounts of customer data according to how recently, how frequently, and how much a customer spends. RFM has been extended in different directions over time, for the purpose of coming up with more detailed segmentations. One such extension adds “length” of the relationship with the customer to the criteria, making LRFM a more effective segmentation method than RFM, especially for the service sector. This chapter describes the use and benefits of using LRFM as a CRM tool in the tourism sector.

Published: March 2020

With the increase in information technology use, problems related to the security of these technologies have become significant. Businesses are required to acquire information, use information technologies, and rely on the information they collected to continue their presence. The requirement of information technology use and related security problems cannot be ignored by both individuals and businesses. One of the industries with large data pools is the tourism industry. Thus, the protection of personal or corporate information is a process that should be managed especially for businesses. In order for this management process to be successful, it is necessary for the corporations to have security policies that are supported by the senior management, possible to implement and understand, and accepted at all corporate levels. Thus, the present study aimed to explain the significance of information security, especially the security of the information in the tourism industry, which is as an important part of the service industry.

This article considers this phenomenon from a theoretical point of view and explores its causes. The author argues that business schools are able to play a key role in bridging theory and practice in marketing. The article closes by offering several suggestions for how business schools might increase the relevance of marketing research while reducing the gap between marketing theory and practice. In particular, the article suggests the adoption of an inductive approach to research and offers a set of policies that business schools can implement in order to close this gap.
Socioeconomic Analysis of the Relationship between the Socioeconomic Characteristics and the Leverage Ratio of Rice Farmers in Anambra State, Nigeria
Authors: Ejiogu Augustine O. , Adikaibe Paschal
Published: March 2020

The burden of poor access to financial services tends to be heavier on rice farmers because of the government's predisposition to bridge rice demand-supply deficit through importation. Improving yields is insufficient to lift rice farmers from poverty. It is necessary to understand and change the system in which the farmers operate one of which is the debt-equity mix of the enterprise. This study analyzed the relationship between socioeconomic characteristics and leverage ratio of rice farmers in Anambra State Nigeria with a view to informing and influencing policy. A hundred rice farmers were randomly selected. Data were analyzed using descriptive statistics and regression analysis. The debt-equity ratio was 0.33. Therefore, the rice farmer could employ more debt to increase yield. In terms of solvency and credit worthiness, the rice farmer had the capacity to employ more debt for profitable investment. Targeted financial and risk management assistance should be extended to the farmers.

Authors: Erkılıç Tuna , Dinç Dilek Temiz , Gökmen Aytaç , Yazıcı Mehmet
Published: March 2020

Energy is a fundamental input of social and economic development of a country. Yet, some of the countries in the world are rich in terms of energy and some countries lack the necessary amount of energy they require. The Republic of Turkey is situated at the threshold of Eurasia and is close to the richest energy basins of the world in its vicinity. However, Turkey is not self-sufficient in terms of energy and in order to correspond to its increasing energy necessity, it must import energy from neighboring countries, mainly from Russia. Moreover, the aim of this study is to analyze the energy trade of Turkey with Russia and its impact on its current account deficit. In order to analyze this issue, various econometric methods are utilized in this study. With respect to this analysis, it is evident that the energy importation of Turkey from Russia leads to an increase in its current account deficit.

Authors: Petre Ionut  Laurentiu , Nica Maria
Published: March 2020

The purpose of this article is to determine if the subsidies granted in the agriculture of Romania influence the economic state of the agriculture, and if so how. After consulting the literature, some authors found that financial interventions are beneficial in some states, and other authors found that in other states the subsidies have a negative impact, so the question arises from the research of this study, which is the influence of granting subsidies on agriculture in Romania?. Data is analyzed regarding the economic accounts in agriculture to determine their evolution, and in the second part of the article an analysis of the coefficients of variation between variables is performed, and following the determination of the dependent and independent variables a model of simple linear regression. Following the correlation of the subsidies with the added value of agriculture it can be considered that the subsidies have a positive impact in Romania, when they increase, and the added value of the agriculture increases.
Bionomics ofScolytus schevyrewi(Coleoptera: Curculionidae) in Saskatchewan and Manitoba, Canada
Authors: Veilleux Jonathan , Ross Fiona , Holliday Neil J.
Published: March 2020

The invasive alienScolytus schevyrewiSemenov (Coleoptera: Curculionidae: Scolytinae) was detected in Saskatchewan and Manitoba, Canada, in 2007. BecauseS. schevyrewiis a potential vector of the Dutch elm disease pathogen (Ophiostomanovo-ulmiBrasier; Fungi: Ophiostomataceae), the natural history of the beetle was studied from 2009 to 2012 in the two provinces, where the disease is managed to protectUlmus americanaLinnaeus (Ulmaceae). Typically, healthy trees become infected when their xylem is contacted during feeding by spore-bearing scolytine adults that have flown from a diseased tree; adults emerging from brood galleries in diseased trees frequently carry spores. We caught flyingS. schevyrewiadults from May to October; adults were weakly attracted to healthyUlmusLinnaeus but were strongly attracted toUlmus pumilaLinnaeus stressed by girdling.Scolytus schevrewicolonised and completed development in girdled trees and trap logs ofU. pumila. In contrast to other studies,U. americana– the major source of pathogen spores in the area – was never colonised as a brood host. Our results suggest thatS. schevyrewiwill primarily useU. pumila, which, in Manitoba and Saskatchewan, seldom exhibits symptoms of Dutch elm disease. Thus, arrival ofS. schevyrewidoes not appear to require changes to Dutch elm disease management programmes.

Published: March 2020

Introduction: Cryptococcal meningitis (CM) is an opportunistic and life-threatening infection, affecting mainly patients with AIDS. The aim of this study was to estimate the prevalence of CM and describe its clinical profile, laboratory parameters, and outcomes in patients with CM in Qatar. Patients and Methods: This retrospective study was conducted at Hamad General Hospital. This study includes all patients admitted to the hospital with CM from January 1, 2005, to December 31, 2015. Results: Eleven patients were included in the study, representing 0.01% of the total admissions and 1.1% of all reported meningitis cases during the study; their mean age was 38.5 ± 12 years. Seven patients (63.6%) were males, and most of them were Filipinos. The most frequent presenting symptom was a headache. Six patients (54.5%) were HIV seropositive, three (27.3%) had preexisting immunosuppressive disorders, and two patients (18.2%) had no risk factors. All the patients tested positive in the cerebrospinal fluid (CSF) India ink examination and had a positive CSF culture for Cryptococcus neoformans. All patients received amphotericin B or liposomal amphotericin B with or without 5-flucytosine as induction treatment. Ten patients received fluconazole as consolidation/maintenance therapy. Eight patients (72.7%) were cured at the end of the treatment period. Two patients (18.2%) left before treatment completion, while one patient (9%) died during admission. Conclusions: CM is rare in Qatar and affects both HIV-positive and HIV-negative expatriates. Clinical presentation is nonspecific and requires a high index of suspicion.

Published: March 2020

The 8th Ramadan and Diabetes International Alliance Annual Conference was held over 2 days on January 24th and 25th in Dubai, United Arab Emirates. The program included six sessions in total. The three states of the art lectures addressed (a) an overview of the current knowledge on insulin therapy during Ramadan, (b) journey of diabetes from EPIDIAR, to CREED and ending by DAR-MENA-T2DM, and (c) feasibility and management of fasting after bariatric surgery. Sessions on the 1st day considered four themes spanning from the impact of Ramadan on physical and mental well-being, efficacy and safety of newer antidiabetic medications during Ramadan, adherence to medications for diabetes and hypothyroidism, and the safety of Ramadan fasting in high-risk groups (cardiovascular and renal). The 2nd day started with a session on bridging the gap between physicians and religious scholars, including a live question and answer session “ask the imam.” The rest of the sessions covered management of type 1 diabetes during Ramadan, patients and doctors perceptions of fasting from various regions and finally a scientific session on nutrition and weight management during Ramadan. RaD activities seem to develop progressively in variety and quality of content and also far-reaching audiences and participants.
A self-designed liver circle for on-demand Pringle's manoeuver in laparoscopic liver resection
Authors: Gao Zhenzhen , Li Zhiwei , Zhou Bo , Chen Lifeng , Shen Zhenhua , Jiang Yuancong , Zheng Xiang , Xiang Jie , Zhang Qiyi , Wang Weilin , Yan Sheng
Published: March 2020

Background:

Laparoscopic liver resection (LLR) allows minimal incisions and relatively quicker post-operative recovery, while intraoperative massive haemorrhage led to conversion to laparotomy. This study aimed to introduce a new, safe and convenient device to serve as Pringle's manoeuver according to the demand in LLR.

Methods:

A liver circle consisting of a hole and a round stem with an obtuse small head was made by medical silica gel. It was applied in LLR to perform on-demand Pringle's manoeuver and developed its function in inferior vena cava (IVC) occlusion. The time of performing Pringle's manoeuver by liver circle, extracorporeal tourniquet and endo intestinal clip under laparoscopic simulator and LLR was compared.

Results:

The liver circle was successfully applied to perform Pringle's manoeuver, IVC exposure and occlusion. It took less time in the occluding step of Pringle's manoeuver than the extracorporeal tourniquet (4.15 ± 0.35 s vs. 9.90 ± 1.15 s, P < 0.05) and the endo intestinal clip (4.15 ± 0.35 s vs. 47.91 ± 3.98 s, P < 0.05) under LLR. The total manipulating time for Pringle's manoeuver with liver circle remained the shortest, and the advantages were more obvious with increased frequencies of intermittent Pringle's manoeuver.

Conclusion:

The new-designed liver circle is more convenient compared to other techniques in performing Pringle's manoeuver, especially the intermittent Pringle's manoeuver in LLR. It can be used to perform on-demand hepatic blood inflow occlusion in every LLR by pre-circling the hepatoduodenal ligament to control bleeding during surgery. It can also be applied to expose the surgical field of vision and perform IVC occlusion to reduce intraoperative blood loss.
A new technique to avoid unintentional adhesion while deploying ProGrip mesh and its utility in the laparoscopic repair of obturator hernia
Authors: Muto Jun , Murakawa Katsuhiko , Yamamoto Hiroyuki , Poudel Saseem , Sato Shoki , Kato Kohei , Senmaru Naoto , Ono Koichi
Published: March 2020

The ProGrip™ laparoscopic self-fixating mesh provides advantages such as low cost and reduced pain following tack-free fixation in laparoscopic hernia repair through a transabdominal preperitoneal approach. Obturator hernia repair needs adequate fixation around the hernial orifice without the use of tacking, and ProGrip™ mesh provides options for secure fixation. However, it is often difficult to adequately adjust the mesh placement to cover the obturator hernia orifice with a ProGrip™ mesh, due to adhesion of the grips to the surrounding tissues. We introduce our technique to avoid unintentional adhesion during ProGrip mesh repair and discuss its utility in the treatment of obturator hernias. We repaired seven obturator hernia lesions in five patients using this technique without any complications. The biggest advantage of our technique is that the position of the mesh can be adjusted after it is expanded, unless the sheet is completely removed, allowing the surgeons to fix the mesh without any unintended adhesion to surrounding tissue.
A comparison of renal vascular control techniques during laparoscopic nephrectomy
Authors: Koc Gokhan , Ekin Gokhan Rahmi , Ergani Batuhan , Ilbey Yusuf Ozlem
Published: March 2020

Background:

We compared outcomes of en bloc stapler ligation of the renal hilum with separate Hem-o-lok polymer clip ligation of the renal vessels during laparoscopic nephrectomy (LN).

Materials and Methods:

Clinical data of patients who underwent LN for renal surgery from January 2009 to December 2015 were collected. Operation time, estimated blood loss, device malfunction rate, open conversion rate, complications and arteriovenous fistula (AVF) formation were evaluated.

Results:

En bloc stapler ligation and separate clip ligation were performed in 64 and 66 patients, respectively. The mean operative time was 106.8 ± 20.8 min (range: 70–165) in the en bloc stapler ligation group compared with 112.5 ± 24.1 min (range: 70–180) in the separate clip ligation group (P = 0.147). The mean estimated blood loss was 141.4 ± 124.1 ml (range: 25–600) in the en bloc stapler ligation group compared with 147.6 ± 112.4 ml (range: 25–450) in the separate clip ligation group (P = 0.767). The open conversion was required in 7/64 (10.9%) and 2/66 (3.0%) patients in the en bloc stapler ligation and separate clip ligation groups, respectively (P = 0.093). Stapler device malfunction occurred in 6 patients (9.3%). There were no statistically significant differences in overall complications (P = 0.726), minor (Grade 1–2) complications (P = 0.698) and major (Grade 3–5) complications (P = 0.716). No patient was diagnosed with AVF formation during overall median 33-month (interquartile range: 30, range: 24–96) follow-up.

Conclusions:

En bloc stapler ligation of the renal hilum during nephrectomy is an effective and safe technique. Although there is no reported AVF formation with en bloc stapler ligation of the renal hilum, longer follow-up is necessary.
El trazado de la elipse en la pintura hasta Caravaggio
Authors: Fraga Fernando , Amado Lorenzo Antonio , Amado Lorenzo Antonio , Colón Alonso Marta , Colón Alonso Marta
Published: March 2020

El círculo está presente en infinidad de elementos de nuestro entorno. Debido a que, visto en perspectiva, es percibido por el ojo como una elipse perfecta, no es descabellado afirmar que esta última es la curva más frecuente en la arquitectura, el arte o la ingeniería. Además, a diferencia de otras formas geométricas simples, su trazado, aún con la ayuda de herramientas como compases o plantillas, conlleva una complejidad importante. Repasar la innumerable cantidad de elipses dibujadas y pintadas desde la antigüedad, confirma que hacerlo con exactitud, a mano alzada, es prácticamente imposible. El artículo estudia la problemática del trazado de la elipse en el arte occidental hasta el siglo xvii. Se parte de la experiencia de Giotto y de los estudios acerca de las cónicas de Durero, para analizar posteriormente cómo una selección representativa de pintores (Campin, Leonardo o Rafael) se enfrentaron a la cuestión sin conseguir resolverla, a diferencia de Caravaggio quien, de alguna manera, lo soluciona (Figs. 1 y 2).
La geometría esférica en la composición arquitectónica. Retos suscitados en la identificación de su forma y función
Authors: Salmerón Nuñez Juan M. , García Sánchez Rafael
Published: March 2020

El espacio arquitectónico al que da lugar el uso de la geometría esférica, posee una destacada carga simbólica. Prueba de ello es que a lo largo de la historia ha sido utilizada en las más notables composiciones arquitectónicas. Sin embargo, en su materialización plantea dificultades geométricas, programáticas  y de ejecución. En particular se abordan los retos suscitados por esta apuesta compositiva, indagando el alcance que provoca la identificación entre forma y función. Destacamos su fuerte vinculación a programas monofuncionales. Se muestra, singularmente eficaz desde tiempos antiguos, para lugares de culto, espectáculos en recintos cubiertos, y más recientemente, la divulgación científica de la astronomía. Asimismo, se constatan las ventajas que ha supuesto el uso de nuevos materiales para una mejor identificación formal.

El documento describe una metodología que cubre los procedimientos de levantamiento y las aplicaciones informáticas con el objetivo de convertir herramientas generalistas (teléfonos inteligentes) en dispositivos de adquisición rigurosa de BIC almacenados en los museos. Dos problemas diferentes se enfrentan: a) como las caracteristicas de dichos objetos a escala micro/meso afectan su documentación; b) desarrollo de una solución multipropósito para una adquisición de bajo costo y fácil de usar para digitalizar y visualizar artefactos BIC. Se presenta un procedimiento basado en un kit de adquisición digital destinado a lograr modelos y texturas confiables, así como representaciones de color precisas. Se han seleccionado varios objetos para probar la coherencia y flexibilidad de los métodos y técnicas propuestos, y los resultados se comparan con los de las técnicas de adquisición estándar.
Evolución técnica y de traza de las escaleras de patio tardomedievales
Authors: Navarro Camallonga Pablo
Published: March 2020

Dentro del ideario de la cantería española, las escaleras representan uno de los tipos más codificados. En el ámbito del gótico meridional, aparecen hacia los siglos xii y xiii los primeros ejemplos de tramos, localizados en patios de casas nobles. Estas se sustentan en arcos, y entre los siglos xiv - xvi, se produce un complejo proceso evolutivo que desemboca, ya en el siglo xvi, en la escalera de caja (Fig. 1).

El artículo plantea una reflexión sobre esta evolución, no tanto por cronología, sino por características arquitectónicas, constructivas, y especialmente por rasgos que  definen una terminología singular en la documentación: Escaleras “capialzadas”, “engauchidas”, “encuentros en redondo”, etc. Términos que nos remiten a  procesos de diseño y que van cambiando con el tiempo. En el artículo estos conceptos se sistematizan con tal de clarificar la confusión que suele producirse en este ámbito.

Interpreting the Claim to Legitimate Authority: an Analysis of Joseph Raz's Objection Against Incorporating Moral Norms into Law
Authors: Peres Ramiro Ávila
Published: March 2020

From a critical review of the literature, we analyze the incompatibility between the possibility of incorporating moral principles to the law and its authoritative nature, as argued by exclusive positivists, such as J. Raz. After presenting his argument in second section, we argue in the third section that it is incompatible with commonly accepted (even by Raz)  premises of the theory of legal interpretation, or else it would lead to contradiction - unless one presupposes, within the premises, a strong version of the sources thesis (which is what Raz intends to prove). In conclusion, we return to the arguments presented, concluding with a possible difficulty for the adoption of exclusive positivism by people inside a legal practice.

Not Just Mortality and Morbidity but Also Function: Opportunities and Challenges for Occupational Therapy in the World Health Organization’s Rehabilitation 2030 Initiative
Authors: Richards Lorie Gage , Vallée Catherine
Published: March 2020

The World Health Organization’s (WHO’s) new focus on rehabilitation offers great opportunities for occupational therapy. Recognizing that the problems in daily function created by the aging of the world’s population and the increasing prevalence of chronic health conditions require rehabilitation to be a vital part of health systems, the World Health Organization brought a variety of stakeholders together in 2017 and 2019 to help them develop the Rehabilitation 2030 initiative. Occupational therapy was represented by the World Federation of Occupational Therapists, the American Journal of Occupational Therapy, the Canadian Journal of Occupational Therapy, editorial board members of several occupational therapy journals, and other occupational therapy researchers. A major challenge to meeting the goal of sufficient rehabilitation services to meet global need is the worldwide shortage of occupational therapists. This shortage can be attributed to a paucity of knowledge about occupational therapy as a health care profession, lack of understanding of the occupational therapy scope of practice, the cost of education required to become an occupational therapist, and the need for occupational therapy salaries to offset educational costs. Nonetheless, ongoing success in research and clinical outcomes will increase knowledge of the value of occupational therapy and increase the size of the profession. WHO’s focus on function is to be lauded. Yet, occupational therapists must not be content with an emphasis on function. They also need to advocate for contextual changes that eliminate barriers to participation and engagement experienced by people with disability.
Unsupervised classification of vertical profiles of dual polarization radar variables
Authors: Tiira Jussi , Moisseev Dmitri
Published: March 2020

Abstract. Vertical profiles of polarimetric radar variables can be used to identify fingerprints of snow growth processes. In order to systematically study such manifestations of precipitation processes, we have developed an unsupervised classification method. The method is based on k-means clustering of vertical profiles of polarimetric radar variables, namely reflectivity, differential reflectivity and specific differential phase. For rain events, the classification is applied to radar profiles truncated at the melting layer top. For the snowfall cases, the surface air temperature is used as an additional input parameter.
The proposed unsupervised classification was applied to 3.5 years of data collected by the Finnish Meteorological Institute Ikaalinen radar. The vertical profiles of radar variables were computed above the University of Helsinki Hyytiälä station, located 64 km east of the radar. Using these data, we show that the profiles of radar variables can be grouped into 10 and 16 classes for rainfall and snowfall events, respectively. These classes seem to capture most important snow growth and ice cloud processes. Using this classification, the main features of the precipitation formation processes, as observed in Finland, are presented.
Relation between the interannual variability in the stratospheric Rossby wave forcing and zonal mean fields suggesting an interhemispheric link in the stratosphere

Abstract. Focusing on the interannual variabilities in the zonal
mean fields and Rossby wave forcing in austral winter, an interhemispheric
coupling in the stratosphere is examined using reanalysis data: the
Modern-Era Retrospective Analysis for Research and Applications, version 2
(MERRA-2). In the present study, the Eliassen–Palm (EP) flux divergence
averaged over the latitude and height regions of 50–30∘ S and 0.3–1 hPa, respectively, are used as a proxy of the
Rossby wave forcing, where the absolute value of the EP flux divergence is
maximized in the winter in the Southern Hemisphere (SH). The interannual
variabilities in the zonal mean temperature and zonal wind are significantly
correlated with the SH Rossby wave forcing in the stratosphere in both the
SH and Northern Hemisphere (NH). The interannual variability in the strength
of the poleward residual mean flow in the SH stratosphere is also correlated
with the strength of the wave forcing. This correlation is significant even
around the Equator at an altitude of 40 km and at NH low latitudes of 20–40 km. The temperature anomaly is consistent with this residual mean flow
anomaly. The relation between the cross-equatorial flow and the zonal mean
absolute angular momentum gradient (M‾y) is examined in the
meridional cross section. The M‾y around the Equator at the
altitude of 40 km is small when the wave forcing is strong, which provides a
pathway for the cross-equatorial residual mean flow. These results indicate
that an interhemispheric coupling is present in the stratosphere through the
meridional circulation modulated by the Rossby wave forcing.

Objective: This study estimates the prevalence in tobacco consumption and the associated factors in adolescents at official educational institutions in the municipality of Palmira.

Methods: This was a crosss-sectional analysis with an analytical component, including 205 high school students from six official schools. The analysis was performed through the SPSS statistics software version 24. Qualitative variables were expressed as ratios with their corrsponding 95 % confidence intervals (CI). Quantitative variables were expressed as central tendency and dispersion measures, depending on the distribution of the variable. Finally, an odds ratio was calculated for the associated factors with a 95 % CI and the binary logistic regression model statistical model was used to adjust the variables.

Results: The tobacco consumption’s overall prevalence was 38.5%, CI 95 % (31.6–45.4 %); e-cigarette, 20 %, 95 % CI (14.2–25.7 %); cigarette, 18.5 %, 95 % CI (12.9–24.1 %) and hookah, 17.9 %, 95 % CI (12.1–23 %), with a greater incidence in women than men. The resulting associated factors were age (OR 3.17, CI 95 % [1.48–6.79]), a partner who smokes (OR 2.51, 95 % CI (1.36–4.63 %), friends who smoke (OR 7.0, 95 % CI [3.4–14.5]), and the possibility of buying individual cigarettes instead of a pack (OR 2.60, 95 % CI (1.26–5.3).

Conclusions: Smoking habit’s overall prevalence is higher than the one reported in adolescents. Female subjects reported greater and more frequent consumption of e-cigarettes.
Democratic Leadership and Attitude towards Time Management of the Student Leaders
Authors: Moneva Jerald C. , Pedrano John Patrick M.
Published: March 2020

Nowadays, lots of students involve themselves in leadership at school which include the class officers wherein they are also known as student leaders who lead democratically. However, while students are practicing democratic leadership at school, some are having a hard time in managing their time properly. Therefore, time management attitude is essential to the students and more importantly to those who are leaders at school. This study aims to determine the association between the level of democratic leadership and the level of time management attitude of the class officers. The data regarding democratic leadership and time management attitude were collected from a sample of 200 class officers from all grade levels in junior high school and senior high school department. With the 200 respondents who answered the survey, the findings of the study revealed that the level of democratic leadership is highly associated with the level of time management attitude. Thus, there is a significant relationship between the level of democratic leadership and the level of time management attitude. Overall, as the level of democratic leadership increases, the level of time management attitude also increases. The study suggests that student leaders like class officers and others should improve their time management attitude through seeking advices for best strategies and to explore more deeply on democratic leadership to be able to successfully apply it in school.
The Impact of Microfinance on Economic Development: The Case of Tunisia
Authors: Barguellil Achouak , Bettayeb Leila
Published: March 2020

This paper aims to study the impact of microfinance on economic development. We used data from the MIX Market (Microfinance Information Exchange), collected from “Enda Tamweel” microfinance institution over the period 1995-2017. The VAR estimation shows that microfinance has a negative and significant impact on the ratio of poverty per capita and the GINI index. Granger's causality test confirms that microfinance contributes more effectively to economic development through its social performance. On the other hand, financial performance gives priority to activities that contribute to the sustainable development of the microfinance institution.
Sequential Coherence as a Success Factor in Personal Selling
Authors: Yapa Shanta R. , Senathiraja R. , Poesche Jurgen , Kauranen Ilkka
Published: March 2020

Personal selling, especially in knowledge intensive contexts, demands effective knowledge transfer between all the parties involved. In our study, we have developed a new conceptual model of sequential coherence that helps to better understand knowledge flows in personal selling. The model describes how social capital, contact intensity, trust and rewards influence sequential coherence. Sequential coherence refers to the reciprocal result of the pushing effects induced by individuals of a teaching firm and the pulling effects induced by individuals of a learning firm that enables knowledge to flow across the boundaries of firms (Yapa et al., 2019). The objective of this concept paper is to explain how sequential coherence can be used as a success factor in personal selling of technology products. Our contribution is useful to both scholars and practitioners.
