Authors: M. S. Bharath , N. S. Sunayana , S. P. Channakeshava 
Published: May 2017

Background: Left bundle branch block (LBBB) indicates organic heart disease. It is commonly associated with ischemic heart disease (IHD), cardiomyopathies, intrinsic disease of conduction system, hypertensive heart disease and acute myocardial infarction can present as new onset LBBB. Purpose of the study was to find out the etiology, outcome in patients having LBBB with respect to left ventricular function coming to our hospital.Methods: All patients coming to our hospital as inpatient or outpatient basis with ECG suggestive of LBBB were studied. Their detailed history was taken and examination was done. 2D-Echocardiography (2D ECHO) was done in all patients and coronary angiogram (CAG) when indicated.Results: Total of 116 patients who had LBBB were studied. Mean age was 62.25±13.75 years. 62 of them were male (53.45%) and 54 were female (46.55%). On presentation 41 patients had dyspnea (35.34%) and 37 had chest pain (31.89%). 24 patients were asymptomatic (20.68%). 59 patients had hypertension (50.86%) and 35 patients had diabetes (30.17%). On 2D ECHO, 39 patients (33.6%) had left ventricular hypertrophy (LVH), with 29 having diastolic and 10 systolic dysfunctions. 26 patients (22.41%) had dilated cardiomyopathy (DCM) and 30 patients had evidence of myocardial infarction (25.86%). 17 patients had normal echocardiography (14.05%). In total 62 patients had systolic dysfunction (53.44%).Conclusions: Commonest clinical presentation was dyspnoea followed by chest pain in patients with LBBB. Most of them had hypertension. LVH was the commonest 2D ECHO finding followed by global hypokinesia and regional wall motion abnormality. Ventricular systolic dysfunction was present in more than 50% patients. CAG revealed coronary artery diseases in majority of cases in whom CAG was indicated.
The Moral and Political Dimension of Economics The Fact-Value Dichotomy
Authors: Almeida Vasco 
Published: May 2017

Since the neoclassical school, the separation between facts and values, is and ought, positive and normative, has become a concern in conventional economic analyses. Economics should focus on facts, and present general principles, leaving the choice of various technical alternatives to policy makers. This article addresses the following questions: can economics, seen as a positive science, be separated from the political dimension? Is it possible to separate facts from values or are they necessarily intertwined?After showing how the separation between economics and moral philosophy unfolded throughout the history of economic thought, the article analyses the factvalue dichotomy discussion and concludes that facts and values are necessarily intertwined. Then, the article shows that the premises and theories of conventional economic theories contain hidden values, despite being presented as universal truths on which policies are based, and thus fail to discuss the various perspectives of the problems.Reviving a tradition commenced by Aristotle, the article concludes by arguing that economics is necessarily moral and political. However, the acknowledgement of the normative nature of economics cannot compromise the pursuit of objectivity.
The Role of Discretion in Professional Practice
Authors: Wajszczyk Piotr 
Published: May 2017

Various scholars of ethics and economics conduct research on the best modes of decision making which guarantee good outcome and moral behaviour of the individuals involved. Either of the modes considered, rules with regulations or discretion and judgment, find applicability in diversified professional circumstances. The paper investigates how discretion can be used in professional activity by using the Aristotelic-Thomistic framework. Results indicate that such a framework can be used by engineers in their working environments and by other working professionals with the main proposition that only in discretionary decision making is the person able to take full responsibility for the outcomes and to premeditate their moral worth in conscience before resolving to commit the act itself.
Employee Subjectivity as a Key Value in Management
Authors: Marek Agnieszka 
Published: May 2017

People, with their knowledge and potential, are undoubtedly the most important part in any organisation because, thanks to them, it might accomplish its goals, gain a competitive advantage and achieve success on the market. That is why each organisation should hire the most appropriate employees and provide working conditions that enable them to unleash their potential for the company’s benefit. The fundamental value for creating a good work environment is employees’ subjectivity, which can be perceived in two ways. The basic level of honouring a person’s subjectivity is respecting human rights and the employee’s dignity in mutual relations. The higher level, though, is to give people a certain amount of autonomy and responsibility in their workplace. The aim of this paper is to identify and analyse interdisciplinary concepts that managers can use in order to ensure that people are given the respect they deserve.
The Phenomenon of Underemployment in Poland
Authors: Cymbranowicz Katarzyna 
Published: May 2017

The labour market is usually associated with phenomena such as unemployment, employment and professional activity/inactivity. The ways in which these categories are shaped depend on various factors of an economic, social and technological nature. It is impossible to disagree with the statement that the contemporary labour market – local, national, and global – is undergoing dynamic changes. In the public debate, the themes of flexicurity, flexible forms of employment, reconciling professional work with private life, and lifelong learning appear more frequently. They cause heated discussions and often also controversies, since their impact on the situation of workers and employers in the labour market is increasing. Observing the trends in the world economy and the global labour market, it can be argued that employment becomes a privilege.Due to the reasons mentioned above, in the paper, issues which relate to ‘incomplete’ employment are discussed. Theoretical considerations are focused on the terminological and methodological problems related to the interpretation of the concept of underemployment both in the Polish and foreign literature. Furthermore, the relationships between the phenomenon of underemployment and the concept of employment flexibility and security are presented, since they are extremely important from the perspective of the contemporary labour market. The theoretical analysis is complemented by a statistical analysis of empirical data that illustrates the current scale of the phenomenon of underemployment in the labour market in Poland compared to other European Union member states (EU-28). The article adopts the research thesis that in Poland there is a problem of ‘incomplete’ employment. Therefore, the aim of this paper is to attempt to identify the scale of this phenomenon on the Polish labour market. Implementation of this objective will be possible thanks to the study of national and foreign literature and a conducted statistical analysis of selected indicators of the labour market in the context of this phenomenon, obtained from the database of the European Statistical Office (Eurostat).
Notes on decolonial dhought and sustainability
Authors: Suguimoto Djmes Yoshilazu de Lima , Fernandes Fernanda Bellucci , Maciel Josemar Campos 
Published: May 2017

Nowadays there is a substantial group of authors that favour the thought about the planet in unorthodox ways, since it is not formed in a Cartesian manner, not only quantified. In the present study scientists who work with the decolonial approach are studied, in other words, modifying the imposed view by groups and economic system in a multicultural society, thinking about the transformation of the planet favoring those who are invisible. All the theorists in this work converge to a fair society, where the respect to different cultures is synonym of a decolonial world being intimately related to the local development theory. This work has as goal to show the criticism these researchers make to the current system, which is aggressive and dissolves many groups that does not accept the modus operandi stablished.

Prefácios, direções, advertências: orientações ao professor nos livros didáticos (1880-1930)
Authors: Ribeiro Fabio 
Published: May 2017

O artigo apresenta pesquisa sobre a presença de orientações aos professores em livros didáticos direcionados ao nível primário e secundário, editados no Brasil entre 1880 e 1930. Pensado para o aluno, o livro escolar é, também, importante recurso para o professor. Referenciando-se nos estudos de Roger Chartier sobre a História do Livro e da Leitura e de Allain Choppin e Circe Bittencourt acerca do livro didático, analisam-se livros de diferentes disciplinas, identificando o conteúdo das instruções, como são apresentadas em cada nível escolar e de que maneira dialogam com o modelo pedagógico em voga. Conclui-se que a presença de subsídios ao docente não era regra para as casas publicadoras e que variava conforme o público a que se destinava. Sugere uma aproximação das orientações nos livros escolares com o conteúdo de revistas pedagógicas da época e suas “receitas para ensinar”. Palavras-chave: livro didático; orientações ao professor; formação docente.
Gênero e reconhecimento no funk carioca: perspectivas para o ensino na educação básica
Authors: Souza Carlos Eduardo Dias , Silva Gladysmeire Guimarães 
Published: May 2017

O uso de personagens históricas negras por vezes nos coloca uma questão: por faltarem registros mais precisos sobre as trajetórias dessas mulheres, abre-se espaço para que se inscrevam em sua biografia aspectos que acabam por fazer de sua representação um “lugar de memória”. Com base na música Não foi Cabral, de MC Carol de Niterói, o artigo aborda a relação entre história, biografia e memória para, em seguida, argumentar que o uso de personagens como Dandara dos Palmares facilita o reconhecimento de outras mulheres negras como agentes de sua própria história. Por fim, espera-se apontar caminhos para que tal reconhecimento atue como ferramenta pedagógica. Palavras-chave: memória; educação étnico-racial; ensino de história.
Emergent Gravity and the Dark Universe
Authors: Verlinde Erik P. 
Published: May 2017

Recent theoretical progress indicates that spacetime and gravity
emerge together from the entanglement structure of an underlying
microscopic theory. These ideas are best understood in Anti-de Sitter
space, where they rely on the area law for entanglement entropy. The
extension to de Sitter space requires taking into account the entropy
and temperature associated with the cosmological horizon. Using insights
from string theory, black hole physics and quantum information theory we
argue that the positive dark energy leads to a thermal volume law
contribution to the entropy that overtakes the area law precisely at the
cosmological horizon. Due to the competition between area and volume law
entanglement the microscopic de Sitter states do not thermalise at
sub-Hubble scales: they exhibit memory effects in the form of an entropy
displacement caused by matter. The emergent laws of gravity contain an
additional ‘dark’ gravitational force describing the ‘elastic’ response
due to the entropy displacement. We derive an estimate of the strength
of this extra force in terms of the baryonic mass, Newton’s constant and
the Hubble acceleration scale a_0 =cH_0a0=cH0,
and provide evidence for the fact that this additional ‘dark
gravity force’ explains the observed phenomena in galaxies and clusters
currently attributed to dark matter.

Polityczne konsekwencje kryzysu migracyjnego w Niemczech
Authors: Sulkowski Mariusz 
Published: May 2017

Artykuł poświęcony jest dwóm równoległym procesom przebiegającym współcześnie w Niemczech – wzmożonej imigracji i coraz silniejszej dezintegracji społecznej. Wysoki napływ imigrantów, w szczególności z Bliskiego Wschodu, powoduje eskalację napięć społecznych na tle etnicznym i religijnym. Przyjęta przez kanclerz Angelę Merkel polityka imigracyjna, której istota streszczona zastała w haśle „damy radę” (Wir schaffen das) okazuje się skutkować coraz silniej dostrzegalnymi podziałami niemieckiego społeczeństwa. Coraz bardziej prawdopodobna staje się teza, że Niemcy nie dadzą rady utrzymać dobrych warunków dla integracji społecznej muzułmanów i pokoju społecznego.

Management of an Extensive Vascular Lesion on the Lip by Photocoagulation with High-Intensity Diode Laser
Authors: Azevedo Luciane H. , Migliari Dante 
Published: May 2017

Objective:
Extensive vascular malformations (VM) pose difficulties for an effective management.

Introduction:
This article describes a very satisfactory result, both functional and aesthetic, following a management by the technique of photocoagulation using diode laser in an extensive VM lesion involving the lower lip and left buccal mucosa in a 25 year old male.

Case report:
The patient reported that the lesion had been present since birth. The whole treatment, carried out under local anesthesia, spread over 6 months since as many as 4 sessions of laser, with a 1.5-month interval in each, were required. The resting period between sessions played an important part in treatment by allowing a time for the recovery of the patient and the shrinking of the lesion.

Conclusion:
The patient had no complications during the laser sessions, and his postoperative period was uneventful. No recurrence has been seen after a 2.5-year follow-up.
Position Specific Changes in Body Composition, Hydration Status and Metabolism During Preseason Training Camp and Nutritional Habits of Division III Football Players
Authors: Jagim Andrew R. , Wright Glenn A. , Kisiolek Jacob , Jones Margaret T. , Oliver Jonathan M. 
Published: May 2017

Background:To what extent pre-season training camp may impact body composition and metabolism in collegiate football players is unknown.Objective:The purpose of this study was to assess changes in body composition, dietary habits and metabolism following pre-season training in Division III American football players.Methods:Seventeen Division III football players (Ht: 1.80±0.6 m; BM: 99.1±60.1 kg; FFM: 79.7±8.6 kg; BF%: 19.3±8.6%) had their body composition and resting energy expenditure (REE) assessed in a fasted state (>12 hr.) before and upon completion of pre-season training. Pre-season training consisted of 14 days of intense training.Results:Linemen had a higher body mass, fat-free mass (FFM), and fat mass likely contributing to the higher REE (p < 0.01). A main effect for time was observed regarding changes in FFM (p<0.001) and body fat % (p = 0.024). A significant interaction was observed for FFM with linemen experiencing a greater reduction in FFM (-1.73±0.37vs.-0.43±0.74 kg; p<0.001). Linemen (L) experienced a greater reduction in REE compared to non-linemen (NL) (L: -223.0±308.4vs.NL: 3.27±200.1 kcals; p=0.085) albeit not statistically significant. Non-linemen consumed a higher amount of daily calories (p=0.036), carbohydrates (p=0.046), and protein (p=0.024) when expressed relative to body mass.Conclusion:The greater size in linemen prior to pre-season likely contributed to their higher REE. However, the multiple training bouts appeared to reduce REE in linemen, which may have been driven by the observed losses in FFM and low protein intake. Further, pre-season training increased body fat % in all players.
Methodological Differences in the Interpretation of Fatigue Data from Repeated Maximal Effort Knee Extensions
Authors: Ciccone Anthony B. , Deckert Jake A. , Herda Trent J. , Gallagher Philip M. , Weir Joseph P. 
Published: May 2017

Background:
Isokinetic fatigue protocols are commonly used in both research as well as in kinesiology education. However, fatigue quantification methods vary between studies.

Objective:
Therefore, the purpose of this study was to determine how fatigue quantification methods affect data interpretation and which methods may be most appropriate.

Method:
In this study, we quantified fatigue from a repeated maximal effort isokinetic knee extension test using different methods, as seen in published research. Nine healthy males and nine healthy females performed 50 concentric knee extensions at 180°•s-1. For each repetition, torque was quantified as either peak torque (PT), torque at the mid-point of the range of motion, and torque integrated over the full, middle 30° range of motion, and isokinetic range of motion. Fatigue Index was quantified using either the first and last three or five repetitions or the peak and last three or five repetitions. Torque slopes were quantified using all repetitions or repetitions that occurred at and beyond the repetition at which the greatest torque value occurred.

Results:
There was a significant inverse relationship between angle at PT and repetition number. Measures of fatigue were overestimated when torque integral over the isokinetic range of motion was utilized. When the first three or first five repetitions were utilized for Fatigue Index calculations, fatigue was underestimated.

Conclusion:
Results suggest that torque integral over the full range of motion is likely the best representation of strength or work. Also, researchers should omit the first few repetitions from their quantification of Fatigue Index or torque slope.
Effect of Four Weeks Detraining on Strength, Power, and Sensorimotor Ability of Adolescent Surfers
Authors: Tran Tai T. , Lundgren Lina , Secomb Josh , Farley Oliver R.L. , Haff G. Gregory , Nimphius Sophia , Newton Robert U. , Brown Lee E. , Sheppard Jeremy M. 
Published: May 2017

Background:
Surfing is a high skill sport that requires a considerable amount of time in a variety of ocean conditions to help develop the fundamental techniques.

Objective:
The purpose of this study was to investigate the effect of four weeks of detraining on strength, power, and sensorimotor ability in adolescent surfers.

Methods:
Nineteen adolescent surfers (13.8 A 1.7 y, 53.6 A 10.8 kg and 165.1 A 8.9 cm) participated in four weeks of detraining (surfing participation maintained but resistance training ceased) following seven weeks of periodized resistance training. Maximal isometric strength, power, and sensorimotor ability pre-test results were determined from the conclusion (post-test) of the first seven-week training block while post-test results were measured at the start (pre-test) of a second seven-week training block.

Results:
Four weeks of detraining significantly decreased the following variables: Vertical jump height by -5.26%, (p=0.037, d= 0.40), vertical jump peak velocity by -3.73% (p=0.001, d= 0.51), isometric strength by -5.5%, (p=0.012, d= 0.22), and relative isometric strength by -7.27% (p=0.003, d= 0.47). Furthermore, sensorimotor ability worsened, with a significant increase of 61.36% (p=0.004, d= 1.01), indicating that athletes took longer to stabilize from a dynamic landing task.

Conclusions:
This demonstrates that surfing, in the absence of resistance training, is not a sufficient training stimulus to maintain physical characteristics. Adolescent surfers with a relatively low training age should avoid cessation of resistance training and strive to maintain consistent resistance training in conjunction with surf training in order to avoid negative decrements in physical characteristics that are associated with surfing performance.
Muscle Mass and Training Status Do Not Affect the Maximum Number of Repetitions in Different Upper-Body Resistance Exercises
Authors: Ferrari Rodrigo , Kothe Gabriela , Bottaro Martim , Cadore Eduardo Lusa , Kruel Luiz Fernando Martins 
Published: May 2017

Background:
Data investigating the factors that influence the relationship between different percentages of one repetition maximum (1RM) and the maximum number of repetitions (RM’s) performed are scarce when the movement velocity of each repetition is controlled during the RM’s test.

Objective:
To evaluate the RM’s performed at 60, 75, and 90% of 1RM in 4 different upper-body free weight exercises: bench press, barbell triceps extension, unilateral dumbbell elbow flexion, unilateral bent knee dumbbell row.

Method:
Thirty participants, 15 trained (T) and 15 untrained (UT) men, volunteered to participate in this study and attended six separate occasions, each separated by at least 48 h. In the first three sessions, familiarization and 1RM tests were evaluated. The last three sessions were designed to assess the performance of the RM’s at 60%, 75%, and 90% 1RM. The exercise order and intensities performed in each session were randomized. Muscle action velocity for each repetition was controlled by an electronic metronome.

Results:
There was no significant difference between T and UT in any of the exercises at a given exercise intensity. Moreover, there was no significant difference in the number of repetitions performed when exercises with different muscle mass (i.e., bench press vs. triceps extension, and dumbbell row vs. elbow flexion) at different intensities (i.e., 60%, 75%, and 90%) were compared.

Conclusion:
Using the same percentage of 1RM, the participants performed a similar number of repetitions in the four free weight upper-body exercises evaluated.
