Managing Information Flow in Self-Organising Networks of Communication Between Construction Project Participants
Authors: Radziszewska-Zielina E. , Śladowski G. , Kania E. , Sroka B. , Szewczyk B. 
Published: September 2019

Abstract
Construction projects are characterised by complexity in the technical, organisational and environmental sphere. The organisational complexity of such projects makes it necessary to manage relationships between actors who fulfil various functions. Formal organisational structures that have been developed for this purpose do not always reflect the actual relationships between construction project participants. In literature, scholars more and more often point to the need to identify and monitor such informal relationships and attempt to manage them in order to effectively carry out projects. Structural analysis of so-called self-organising networks of relationships between project participants is carried out on the basis of established structural measures by performing Social Network Analysis (SNA). In a situation when inappropriate communication between project participants relative to management staff expectations is detected, interventions meant to improve communication in such networks are possible. The goal of the article is proposing an optimisation-oriented approach to planning such interventions while taking various constraints, such as communication costs, into consideration. As a part of this optimisation, the authors proposed a method from the heuristic methods group. This solution will support decision-making in terms of intervening within an informal relationship structure. The method was presented on the example of an actual construction project involving the construction of a complex of housing buildings. the self-organising network structure was defined on the basis of a survey carried out among the project’s participants and concerned communication between them over a four-week period. As a result of the structural network analysis, abnormalities in communication between project participants were detected. The optimisation method developed by the authors pointed to possibilities of improving communication effectiveness within this network. The effects of the analysis confirmed the application potential of the method that was presented.

Authors: Rondón-Quintana H. A. , Ruge-Cardenas J. C. , Bastidas-Martínez J. G. 
Published: September 2019

AbstractIron production’s waste materials include significant quantities of blast furnace slag (BFS) which could potentially be used as a substitute for natural aggregates in hot mix asphalt (HMA) used in highway projects. Although many of properties of slag are interesting, its porosity and absorption rate would lead to greater consumption of asphalt. For this study, a Portland cement (PC) paste was used to reduce the porosity of a BFS. This PC treated BFS (called BFS-C) was then used in an HMA to replace the coarse fraction of a natural aggregate. Marshall, Indirect Tensile Strength (ITS), resilient modulus and Cantabro tests were then carried out on different HMA mixtures that included BFS-C. Using BFS-C, HMA’s resistance under monotonic loading, stiffness under cyclic loading, and resistance to moisture damage increased remarkably. In addition, the Cantabro abrasion resistance of BFS-C improved was better than that of the HMA mixture produced with untreated BFS.
Performance Evaluation on Selection of Formwork Systems in High Rise Buildings Using Regression Analysis and Their Impacts on Project Success
Authors: Rajeshkumar Viswanathan , Sreevidya V. 
Published: September 2019

AbstractThe selection of the formwork system for high rise building affects the entire construction project duration and cost. The study reports the factors influencing the selection of different formwork system in the construction of high rise buildings through structural questionnaire survey from the client, contractor, consultant, and interviews with expert members. Total of 40 technical factors was identified from the literature and 220 filled questionnaires were received from the respondent. Relative Importance Index method is used to find the topmost factors affecting the selection of formwork system. Additionally, from factor analysis 22 factors were identified to have a correlation with one another. Regression analysis reveals that duration of the project, maintenance cost, adaptability, and safety have impact on formwork selection across time, cost and quality. These findings could potentially increase the construction company’s existing knowledge in relation to formwork selection.

Published: September 2019

Abstract
The main objective of this work is the numerical analysis of the strength and stiffness of an annular three-layer circular plate with variable mechanical properties of the core. The plates are subjected to bending. Numerical analysis of the deflection phenomenon is carried out under different support conditions of the plate. Furthermore, the influence of the material properties of the core (linear and non-linear model) on the shear stresses and deflecions is also investigated.
Unemployment Impact of Product and Labor Market Regulation: Evidence from European Countries
Authors: Piton Céline , Rycx François 
Published: September 2019

Abstract
This paper provides robust estimates of the impact of both product and labor market regulations on unemployment using data from 24 European countries over the period 1998–2013. Controlling for country fixed effects, endogeneity, and a large set of covariates, results show that product market deregulation overall reduces the unemployment rate. This finding is robust across all specifications and in line with theoretical predictions. However, not all types of reforms have the same effect: deregulation of state controls and in particular involvement in business operations tend to push up the unemployment rate. Labor market deregulation, proxied by the employment protection legislation index, is detrimental to unemployment in the short run, while a positive impact (i.e., a reduction in the unemployment rate) occurs only in the long run. Analysis by sub-indicators shows that reducing protection against collective dismissals helps in reducing the unemployment rate. The unemployment rate equation is also estimated for different categories of workers. Although men and women are equally affected by product and labor market deregulations, workers distinguished by age and educational attainment are affected differently. In terms of employment protection, young workers are almost twice as strongly affected as older workers. Regarding product market deregulation, highly educated individuals are less impacted than low- and middle-educated workers.
How Similar are Pharmacy Students and White Blood Cells? Curricular Content Reinforced Through Personification
Authors: Ware Kenric 
Published: September 2019

Description: This initiative sought to evaluate the use of personification to reinforce immunology concepts among pharmacy students. A two-part question posed to first year pharmacy students asked if they could physically become two white blood cells (WBCs), which would they choose and why. Students received instruction in immunology prior to providing their feedback. Demographics included campus of enrollment and gender designation. Student ratings 1 to 5 reflected approval levels toward this activity’s usefulness (1: least; 5 most).
Key Findings: One hundred and ten of 117 students selected two WBCs they would physically become if possible (94%). Less than two-thirds of students were female (63%) and the Columbia campus featured approximately a quarter of the students (24%). The most and least common WBCs chosen, as first selections by campus and gender, were statistically significant being neutrophils and basophils, lymphocytes and eosinophils, respectively. The median approval values of the WBC personification activity by campus and gender were similar and did not reach statistical significance, 4.5 and 5, respectively.
Conclusion: Pharmacy students commended the personification activity for helping them learn the roles and responsibilities of WBCs. Unique and insightful rationales for the choices made for WBCs persisted among the students. In light of these favorable reviews, this type of activity can be adapted to other areas of pharmacy education.

Published: September 2019

Typhoid fever is one of the infectious diseases which can cause many problems in Indonesia and other developing countries. This fever occurs as a result of infections triggered by Salmonella typhi bacteria. The growth of Salmonella typhi can be inhibited using antibiotics. This study aims at investigating whether there is a difference in the sensitivity test of Salmonella typhi bacteria in an isolate of patients with typhoid fever and pure culture in a laboratory on some antibiotics.Salmonella typhi bacteria were isolated typhoid fever suspects at one of the hospitals in Surakarta. Pure cultures of Salmonella typhi bacteria were obtained from Microbiological Laboratory of Setia Budi University. Sensitivity test of antibiotics on Salmonella typhi bacteria used diffusion method. Data on antibiotics of inhibition zone diameter (mm) of antibiotics were analyzed statistically using the Two-Way Anova test.The research results demonstrate that the sensitivity test on Salmonella typhi bacteria in an isolate of patients with typhoid fever shows resistance (R) towards amoxicillin and sensitivity (S) towards trimethoprim, chloramphenicol, gentamicin, ciprofloxacin. Meanwhile, pure culture shows sensitivity (S) towards trimethoprim, chloramphenicol, gentamicin, amoxicillin, ciprofloxacin. The diameter of the inhibition zone of the patient isolate is smaller than that of pure culture.
Organic matter in rock–water systems of petroliferous basins: interrelationships (a case study: South Caspian Basin)
Authors: Feyzullayev Akper A. , Lerche Ian 
Published: September 2019

Generalizations and analyses are given of the data accumulated to date on the content of Organic Matter (OM) in formation waters of various stratigraphic complexes, as well as of mud volcanoes, and the correlation with OM in South Caspian Basin (SCB) sedimentary rocks. Results are based on about 300 analyses of formation waters and waters of mud volcanoes, as well as on more than 400 analyses of the content of OM in rocks (outcrops and wells from both onshore and offshore petroleum fields of the SCB). The stratigraphic interval covers the period from the Lower Pliocene to the Jurassic, and the depth interval from 73 m to 6043 m. In these intervals, the values of Dissolved Organic Matter (DOM) in reservoir waters vary from 4.1 mg/L to 271.2 mg/L, averaging (219 analyses) 48.9 mg/L. A good correlation has been established between the values of DOM and OM in rocks. Paleogene and Jurassic rocks have the highest correlations. DOM varies with depth with an increase in value from a depth of about 3.3 km, likely due to catagenetic transformation of OM into hydrocarbons in the rock–water system. The highest values of DOM are for waters with mineralization less than 50 g/L. Mud volcano waters are characterized by low levels of DOM and low mineralization, likely due to the condensate nature. The results of the studies show that underground water, as one of the components of a single rock–water system of the Earth’s sedimentary cover, together with the rocks, participates in the processes of hydrocarbon generation and migration.

Authors: Naqvi Asad , Ariyanayagam Timothy , Ali Mir Akber , Rachakonda Akhila , Choudur Hema N. 
Published: September 2019

Objective:
The objective of this study was to outline a novel unique concept of secondary impingement of the muscles, myotendons, and tendons of the rotator cuff from hypertrophy as a result of strength training exercises.

Methods:
In this retrospective observational study, 58 patients were referred for an magnetic resonance imaging (MRI) by the orthopedic surgeon to the radiology department over a period of 1½ years. All patients gave a history of strength training exercises and presented with clinical features of rotator cuff impingement.

Results:
We identified features of hypertrophy of rotator cuff muscles, myotendons, and tendons in 12 of these 58 patients. This was the only abnormality on MRI. The hypertrophy of rotator cuff muscles and tendon bulk completely filling the subacromial space to the point of overfilling and resulting in secondary compressive features.

Conclusion:
Rotator cuff impingement is a common phenomenon that can occur with various inlet and outlet pathological conditions. However, rotator cuff impingement may also result from muscle and tendon hypertrophy from strength training regimens. Hypertrophy of the rotator cuff can result in overfilling of the subacromial space, leading to secondary impingement, which we have termed as “pseudo-impingement.”
Comparison of retention of two proximal sealants in mandibular first molars of 12-year-old school children - A split-mouth randomized trial
Authors: Sankar Brinda Bhavani , Kumar Madan 
Published: September 2019

Aim:
This study was done to assess and compare the retention properties of a proximal sealant made of polyurethane dimethacrylate and a resin-based adhesive system for sealing proximal surfaces of permanent mandibular first molars in 12-year-old children over a period of 6 months.

Methodology:
A split-mouth randomized trial was conducted among 50 school children. Pre-operative and post-operative bitewing radiographs were taken bilaterally prior at baseline and the end of the sixth month. Separators were placed for those children who did not have physiological spacing. The interventions were delivered on the left and right sides after randomization as per the manufacturer’s instructions, and post-operative instructions were given to the participants. The interventions were assessed for retention primarily and other criteria such as color match, marginal discoloration, marginal adaptation, anatomic form, caries formation (using bitewing radiographs), post-operative sensitivity, and surface roughness at the end of the 1st, 3rd, and 6 months using United States Public Health Service Modified Ryge Criteria for Direct Clinical Evaluation of Restorations proposed by Cvar and Ryge, 1980. The data were compiled, analyzed using SPSS and results were generated.

Conclusions:
The study results revealed that the resin-based adhesive system was better than the adhesive patch in terms of retention over a period of 6 months. Hence, the feasibility of including proximal sealants as a part of the preventive regimen for caries risk children should be positively considered.

Published: September 2019

Introduction:
Dental anxiety remains a barrier to dental care for a considerable proportion of the population. The psychological profile of patients dentally anxious but not highly anxious is quite similar to normal (non-anxious) patients’ profile.

Aims and Objectives:
The aim of the study is to assess personality traits and prevalence of dental anxiety and to find an association between dental anxiety and personality traits in arts students.

Materials and Methods:
A cross-sectional study was conducted among 130 arts students out of which 86 were males and 44 were females. Modified dental anxiety scale was used to measure dental anxiety using a five-point Likert scale. Personality trait was assessed using the short-form revised Eysenck personality questionnaire scale which consisted of 48 questions. Statistical analysis was done using independent t-test with statistical significance at 5%.

Results:
Overall prevalence of dental anxiety was 56.93% (males 53.38% and females 63.63%). The mean score of dental anxiety for males was 9.6 ± 3.7 and for females 11.3 ± 4.2, and difference was statistically significant (P < 0.05). A total of 30 (23.07%) were classified as extraversion, 24 (18.46%) as neuroticism, 32 (24.61%) as lie scale, and 20 (15.38%) as psychoticism according to the scale used. In the present study, there was no association between dental anxiety and personality trait.

Conclusion:
In general, dental anxiety is not gender related, but in the present study, females had higher dental anxiety (63.63%) compared to males (53.38%).
Childhood trauma and Effective Empirically Based Interventions
Authors: Wilson Shanika Lavi 
Published: September 2019

Trauma affects many children in various ways globally. According to SAMHSA (2017), the “occurrence of child trauma is very prevalent, and 75% of children reported experiencing at least one traumatic event by age 16”. Traumatic events consist of “psychological, physical, or sexual abuse; community or school violence; witnessing or experiencing domestic violence; national disasters or terrorism; commercial sexual exploitation; sudden or violent loss of a loved one; refugee or war experiences; military family-related stressors; physical or sexual assault; neglect; and serious accidents or life-threatening illness” (SAMHSA, 2017). This literature review evaluates three different attachment-based, trauma-informed interventions for young children 0 - 7 years of age which are: Attachment and BioBehavioural Catchup (ABC), Child-Parent Psychotherapy (CPP), and Parent-Child Interaction Therapy (PCIT). Throughout this review, childhood trauma will be defined, and the current occurrence rates will be discussed. Furthermore, the descriptions of the above therapies, clinical trials, and research findings will be examined, and a discussion of the literature review findings will follow.

Se configura la segunda síntesis de la teoría evolutiva
Authors: Báez Tobar Oswaldo 
Published: September 2019

La teoría evolutiva es la teoría fundamental de la biología. Se presentó a la comunidad científica en dos pequeños ensayos sobre la evolución por selección natural preparados en forma independiente por Charles Darwin y Alfred R. Wallace. Luego de la publicación del principal libro de Darwin: El Origen de las Especies -que aporta numerosas pruebas y una amplia explicación de la teoría de la descendencia-, el pensamiento evolucionista fue denominado: Darwinismo.
Con el avance de las ciencias de la vida a mediados del siglo XX se reformuló el darwinismo clásico en un nuevo corpus: la Teoría Sintética de la Evolución o Neodarwinismo que se sustenta en la genética mendeliana y la genética de poblaciones; sobre esta base se construyó el pensamiento evolucionista moderno que tuvo vigencia plena en casi todo el siglo pasado.
Surgieron cuestionamientos en el seno del neodarwinismo que no pusieron en duda la validez de la teoría de evolución por selección natural, pero que llevaron a incorporan otros factores explicativos de la transformación evolutiva, además de la selección. En esa perspectiva se viene trabajando en las últimas décadas, al punto que se habla ya de una segunda síntesis de la teoría de evolución o Síntesis Expandida, que emerge del marco conceptual de la genética molecular, la genómica, la biología del desarrollo y la ecología; razón por la cual a este nuevo paradigma se lo conoce también como Eco-Evo-Devo.
Si la Teoría Sintética de la Evolución fue uno de avances mayores de las ciencias biológicas del siglo anterior, la segunda síntesis o Síntesis Expandida, se perfila como la construcción teórica más trascendental de la biología actual.
El lugar que ocupa el sumak kawsay en el debate teórico sobre desarrollo alternativo y alternativas al desarrollo capitalista
Authors: García Álvarez Santiago 
Published: September 2019

Este artículo tiene como objetivo principal situar al sumak kawsay o buen vivir en el marco del debate sobre alternativas al desarrollo capitalista, que a su vez comprenden planteamientos más profundos y de largo alcance que el desarrollo alternativo. Creemos que es indispensable acometer con este propósito para evitar errores sobre el sumak kawsay, que si bien proviene de las críticas y aportes de las culturas ancestrales andinas, sin embargo, no termina como propuesta eminentemente culturalista de regreso al pasado, sino que se enmarca críticamente y de una forma holística en la tendencia universal de buscar nuevas visiones sobre bienestar humano, equidad y armonía con la naturaleza, más allá del economicismo fundamentado en los mercados.
Innovación en metodologías didácticas y “Aprender a Aprender”
Authors: Romo Pablo 
Published: September 2019

La innovación educativa requiere repensar la educación y realizar actividades que tiendan a romper las estructuras tradicionales para mejorar los procesos educativos en cualquiera de sus aspectos. Uno de los aspectos en el que se debe innovar es el de las metodologías didácticas a través del desarrollo de destrezas intelectuales que fomenten en los estudiantes el aprender a aprender. La propuesta se compone de cinco pasos que deben ser manejados por el docente y un proceso explícito que debe ser conocido tanto por el docente como por el estudiante. Los cinco pasos son: definir la destreza, ejemplificar desde un caso real, proceso didáctico para el desarrollo de la destreza, ejemplificar con un caso de la asignatura, aplicar en un ejercicio distinto en forma individual o en equipos. De estos pasos el número tres es fundamental en la propuesta pues requiere que el maestro indique en forma explícita los momentos que requiere el desarrollo de cada destreza lógico intelectual (observar, describir, clasificar, comparar, relacionar, definir, analizar, sintetizar…). En cada momento se debe realizar procesos para el desarrollo de la capacidad intelectual del estudiante que a la vez lo lleven a aprender a aprender desde sus propias experiencias y procesos, esto permitirá fomentar y desarrollar un pensamiento complejo y creativo.
