Microstructure and Mechanical Properties of Friction Stir Processed A356 Cast Al under Air Cooling and Water Cooling
Authors: Ai Xinxin , Yue Yumei
Published: June 2018

In this work, friction stir processing (FSP) was used to modify the microstructure of A356 cast aluminum alloy under air cooling and water cooling conditions. The microstructure and mechanical properties of air cooling and water cooling FSP specimens and their differences were mainly discussed. Results show that the grains can be significantly refined after FSP under both air cooling and water cooling conditions. The water cooling FSP specimen shows much smaller grains than the air cooling FSP specimen due to lower temperature. Similarly, the Si particles of water cooling FSP specimen show much smaller sizes and better distribution. Both the air cooling FSP specimen and water cooling FSP specimen own much higher tensile strength and elongation than A356 base material (BM). In particular, the tensile strength and elongation of water cooling specimen are respectively 231 Mpa and 14.15%, which are equal to 186.3% and 1088.5% of the BM. Furthermore, the microhardness of water cooling FSP specimen is lower than that of the air cooling FSP specimen.

This paper is interested in the role and space ‘conservative’ poetical realist literature was granted in the German Empire’s 19th century public discourse around environmental pollution and its impact on social inequality. Wilhelm Raabe’s novel Pfister’s Mill serves as a case study, as this literary work discusses the unwanted side effects of the young nation state’s transformation from an agricultural to an industrial society based on a contemporaneous legal incident.
Edible Plant Oil Wastewater Treatment Using Electro-Fenton Technique: Experiment and Correlation
Authors: Davarnejad Reza , Mohajerani Seyed Amir
Published: June 2018

The edible plant oil production factories consume high amounts of water and contaminate the water resources. This type of wastewater consists of high chemical oxygen demand (COD) which should properly be treated by an efficient technique. Furthermore, it is containing some chemicals obtained from several sources such as H3PO4 (from hydration section), NaOH (from neutralization section) and citric acid (from nickel removal section). The conventional techniques cannot efficiently treat it which is full of COD. Therefore, the electro-Fenton process as a rapid, compact and efficient one has been encouraged to be applied. For this purpose, 47 experiments were designed and carried out using iron electrodes to evaluate the effects of five significant independent variables such as reaction time (min), pH, current density (mA/cm2), volume ratio of H2O2/wastewater (ml/l) and H2O2/Fe2+ molar ratio on the COD removal. Response surface methodology (RSM) was employed to assess individual and interactive effects of the parameters. The optimum conditions were experimentally obtained at reaction time of 87.33 min, pH of 3.03, current density of 57 mA/cm2, H2O2/wastewater volume ratio of 2.13 ml/l and H2O2/Fe2+ molar ratio of 3.61 for COD removal of 62.94 %.
Optimal Control of an Endoreversible Solar Power Plant
Authors: Schwalbe Karsten , Hoffmann Karl Heinz
Published: June 2018

While in the classic Curzon–Ahlborn and Novikov engines the temperatures of the heat baths are kept fixed or follow a deterministic time function, it is the aim of this work to study the impact of fluctuating heat bath temperatures. As an example serves a solar power plant, where the stochastically varying cloud cover leads to fluctuations in the temperature of the hot heat bath. This solar thermal power plant is modeled as a stochastic endoreversible system. On the basis of this model the maximum expected work output of the power plant and the corresponding optimal control policy is derived. For the considered system it is found that the maximum expected work output changes with the reversion speed of the hot temperature depending on the relation of the starting hot temperature and the temperature of the power plant’s receiver. Additionally, it is found that the maximum expected work output increases with the hot temperature’s fluctuation strength.
A network diffusion ranking family that includes the methods of Markov, Massey, and Colley
Authors: Devlin Stephen , Treloar Thomas
Published: June 2018

We present a one parameter family of ratings and rankings that includes the Markov method, as well as the methods of Colley and Massey as particular cases. The rankings are based on a natural network diffusion process that unites the methodologies above in a common framework and brings strong intuition to how and why they differ. We also explore the behavior of the ranking family using both real and simulated data.
An algorithm based on a new DQM with modified exponential cubic B-splines for solving hyperbolic telegraph equation in (2 + 1) dimension
Authors: Singh Brajesh Kumar , Kumar Pramod
Published: June 2018

In this paper, a new methodmodified exponential cubic B-Spline differential quadrature method(mExp-DQM) has been developed for space discretization together with a time integration algorithm for numeric study of (2 + 1) dimensional hyperbolic telegraph equations. The mExp-DQM (i.e., differential quadrature method with modified exponential cubic B-splines as new basis) reduces the problem into an amenable system of ordinary differential equations (ODEs), in time. The time integration SSP-RK54 algorithm has been adopted to solve the resulting system of ODEs. The proposed method is shown stable by computing the eigenvalues of the coefficients matrices while the accuracy of the method is illustrated in terms ofL2andL∞error norms for each problem. A comparison of mExp-DQM solutions with the results of the other numerical methods has been carried out for various space sizes and time step sizes.
Quantum Theory and the Structure of Space-Time
Authors: Singh Tejinder P.
Published: June 2018

We argue that space and space-time emerge as a consequence of the dynamical collapse of the wave function of macroscopic objects. Locality and separability are properties of our approximate, emergent universe. At the fundamental level, space-time is non-commutative, and its dynamics is non-local and non-separable.

The principles of rational chemotherapy of bacterial infections in poultry
Authors: Tykałowski B. , Koncicki A.
Published: June 2018

Growing levels of microbial resistance to chemotherapeutic agents pose a threat to public health and constitute a global problem. The above can be often attributed to improper and excessive use of antibacterial drugs in veterinary and human medicine, animal breeding, agriculture and industry. To address this problem, veterinary and human health practitioners, animal breeders and the public have to be made aware of the consequences and threats associated with the uncontrolled use of antibacterial preparations. In recent years, many countries have implemented programs for monitoring antibiotic resistance which provide valuable information about the applied antibiotics and the resistance of various bacterial species colonizing livestock, poultry and the environment. Special attention should be paid to the sources and transmission routes of antibiotic resistance. There are no easy solutions to this highly complex problem. The relevant measures should address multiple factors, beginning from rational and controlled use of chemotherapeutic agents in veterinary practice, to biosecurity in animal farms, food production hygiene, and sanitary and veterinary inspections in the food chain. The tissues of treated birds should not contain antibiotic residues upon slaughter. Rational use of antibiotics should minimize the risk of drug resistance and decrease treatment costs without compromising the efficacy of treatment. Therefore, the key principles of antibiotic therapy of bacterial infections in poultry should be the adequate selection and dosage of the administered drug, a sound knowledge of the drug’s pharmacokinetic and pharmacodynamic properties, as well as a knowledge of the differences between bacteriostatic and bactericidal drugs and between time-dependent and concentration-dependent drugs. There is an urgent need to revise the existing approach to the use of chemotherapeutic agents in the treatment of poultry diseases, and to increase the awareness that antibiotics cannot compensate for the failure to observe the fundamental principles of biosecurity in all stages of poultry farming.

Published: June 2018

It was first conducted testing on antimicrobial activity of Galega orientalis (La) on the growth pure cultural of bacteria gram positive (Micrococcus luteus), gram negative (Escherichia coli XL1, DH5) and yeasts (Saccharomyces cerevisiae W303). The material for the study was dried vegetative mass Galega orientalis (Lam) in the phase of budding and early flowering. In experiment used medium «Endo» for gram negative, medium LB for gram positive and gram negative, and suslo agar for yeasts. As a result of the experiment was revealed that 20% concentration of aqueous extract of this plant had inhibitory effects on the growth of pure cultures of bacteria and yeast. Antimicrobial effect of this drug on the growth of gram-negative bacteria (Escherichia coli XL1, DH5) were within 20.0–30.0% (P < 0.001), gram-positive bacteria (M. Luteus) – 12.0% (P < 0.05) and yeast (S. cerevisiae W303) – 30.5% (P < 0.01) compared with control. It should be noted that in all cases the addition of the drug Galega orientalis (La) did not alter the morphology of colonies (colony size) test strains. The questions of search the new antimicrobial agents, include natural origin, is very actual during last years. Increasing microbiological pure of eating products, feed grinders, veterinarian preparations are one of the urgent task of Scientifics and industrials. It has proved the influence of different concentrations of aqueous extract of this culture on the growth of pure cultures of gram-positive and gram-negative bacteria and yeast. Install antimicrobial influence 20–30% concentrations of preparation on the bacteries growth (Escherichia coli XL1, DH5). Bacterial action of preparation on the bacteries (Micrococcus luteus) and yeasts (Saccharomyces cerevisiae W303) were lower. It was described the prospects for further investigation of this problem. It has proved possible relationship between the antimicrobial activity of the extract of this plant and bloating of the rumen in ruminants.
"Fiscellas iunco texens" some classical allusions in Jerome's Vita Hilarionis, Ch. 5
Authors: Pataki Elvira
Published: June 2018

The study focuses on a hidden classical allusion that has remained undetected in the biography of St. Hilarion. The young monk, tempted by carnal desire, tries to escape sin by fasting, praying and basket-weaving. Describing this last method, Jerome refers not only to the well-know monastic activity and the sentence of St. Paul - qui non operatur non manducet - but depicts basket-work as a remedy for love, an allusion to the erotic context of Virgil's Third Eclogue.
Βουβρωστισ (Hom.，Il. 24，531 ff.) Die entwicklung einer wortbedeutung
Authors: Pötscher Walter
Published: June 2018

The word βούβρωστις is problematic. In Horn., Il. 24, 532 it meant a goddess "who devours the cattle". The starting point of this concept is the idea that cattle might be stolen at any time, and the owner, not understanding it, interprets the disappearance as a malign act of such a goddess. As the result of a complex development, the word βούβρωστις has later taken on the meaning of "ravenous hunger".

Some generic problems of senecan drama
Authors: Ferenczi Attila
Published: June 2018

The messenger speeches in some of Seneca's tragedies (the most extensive ones can be read in Agamemnon and Hercules Furens) constitute special epic details of the works. Their narrative technique, intertextual references and representation of time link them not with the dramatic literary form, but with the epic one, and Vergil's Aeneid is, beyond any doubt, their most important 'hypertextus'. The setting of the messenger reports has not been subordinated to the dramatic efficacy of the main conflict, they produce rather a generic multiplicity. The reform of closed literary forms and the generic heterogeneity are not unique phenomena in the literary life of this period; the meaning and importance of the innovation made by Seneca cannot be judged separately from the most important literary achievements of the period: Luc an's Bellum Civile and Petronius' Satyricon

Authors: Javeed Aysha , Salleh Sazlina , Darif Aqilah , Mohammad Mahadi
Published: June 2018

This study describes the morphological structure of Thalassiosira spp. found in coastal water and intertidal area of Teluk Bahang, Penang. Examination of the samples collected from January 2015 to June 2016 showed that these species were the common genera in both benthic and surface seawater at Teluk Bahang. To obtain phytoplankton samples, five liters of seawater were filtered through the plankton net (35 µm). While for benthic samples, the samples were collected at sediment surface of 1 mm depth. Samples of Thalassiosira spp. were obtained from both phytoplankton and benthic samples. Scanning electron microscope (SEM) was used to study the morphology of Thalassiosira spp. Results from the SEM showed distinct differences in areolae pattern, sizes, position and number of processes among Thalassiosira spp. (Thalassiosira nanolineata, Thalassiosira densannula, and Thalassiosira gravida). Thalassiosira densannula and Thalassiosira nanolineata were found in both habitats, coastal and benthic area while Thalassiosira gravida was found only in coastal water. Thalassiosira spp. contribute approximately 15% of the total benthic community and approximately 35% of the total phytoplankton community.

Proclaiming East Timor: Historical Reflections on Political Declarations
Authors: Kammen Douglas
Published: June 2018

East Timor celebrated its independence in 2002, but behind the euphoria the subject of the celebration was hotly contested. While most foreign observers treated this as the achievement of independence, according to the Constitution and the first government 20 May 2002 marked the restoration of independence that was first proclaimed by Francisco Xavier do Amaral in November 1975. Given the significance that declarations of independence hold, this article traces the history of political declarations in East Timor over the course of three centuries. It examines a curious pair of declarations in 1702-1703, the many declarations of vassalage in the nineteenth century, the declaration of the Portuguese Republic in 1910, the competing political declarations in 1975, and a curious declaration of a breakaway republic in 2005.
“An East, east of the East” Eça de Queirós’ A Relíquia, Álvaro de Campos’ “Opiary” and the Postimperial Scope of Portuguese Literary Orientalism
Authors: Schacht Pereira Pedro
Published: June 2018

Coming to terms with the increasing peripherality of Portugal at the height of Europe’s “Scramble for Africa” and in its immediate wake, both Eça de Queirós and Fernando Pessoa’s Álvaro de Campos engage with orientalism reactively, setting the stage for a prescient critique of European representations of the Orient. Through the parody of nineteenth-century religious and scientific discourses (Eça), and of symbolist poetics (Álvaro de Campos), as well as the recontextualization of early-modern Portuguese travel writing tropes, these two writers propose two alternative understandings of Portugal’s specific position in the modern geopolitics of empire. This article argues that the prescience of Eça’s and Pessoa’s critiques of orientalism forecloses, rather than authorizes, future essentialist views of Portugal’s historical specificity as evidence of exceptionalism.
Un-servile Servants: Misfits of the Azorean Diaspora in Charles Expilly’s Le Brésil tel qu’il est (1862)
Authors: Roncador Sonia
Published: June 2018

Focusing on the “problem” of domestic un-governability in mid-century Brazil, this essay discloses early stereotypes of white (Portuguese Azorean) servants as arrogant, lazy and self-interested. If, on one hand, such degrading stereotypes provided elite Brazilians with what Michael Pickering has called a “comfort of inflexibility,” on the other hand, these representations also shed light on the vulnerability of employers’ domestic authority and social-conflict management in post-colonial Brazil, particularly in the decades leading up to the abolition of slavery in 1888.

An Arcadian Poet in a Baroque City: Cláudio Manuel da Costa’s Urban Pastorals, Family Life, and the Appearance of Race
Authors: Carvalho Bruno
Published: June 2018

With focus on Cláudio Manuel da Costa and his life in eighteenth-century Minas Gerais, this article places into dialogue seemingly contradictory notions of baroque urbanism, art, and poetics. It explores how Cláudio’s work engages baroque and Arcadian tropes, re-writing pastoral conventions with awareness of the production of nature through artifice. Some of his poems emerge as narratives of wilderness subsumed by colonial forces, others offer clues about his relationship with Francisca Arcângela de Souza, a woman of African descent (archival findings about her are presented here for the first time). Cláudio Manuel da Costa, a writer and public gure of many masks, helps us to make sense of tensions, changes, and apparent paradoxes of the period.
Narratives of Power and Resistance in Jorge de Sena’s O Físico Prodigioso
Authors: Atkin Rhian
Published: June 2018

This article examines Jorge de Sena’s interrogation of power and resistance in O Físico Prodigioso (1966). While the second half of the novella functions as a clear allegory for the Portuguese and Brazilian dictatorships of the mid-twentieth century, political oppression and repression are in fact deeply ingrained in Sena’s vision of society. The apparent freedom that is witnessed before and after dictatorship is not (and cannot be) universal, because for Sena even the power of discourse holds the potential for oppression. Drawing on Foucault’s work, the article posits that O Físico Prodigioso’s shifting narrative functions as a call for continual resistance against oppression in all of its forms.
Um ‘quase-africano:’ Re-significações de Fradique Mendes em Nação crioula, de José Eduardo Agualusa
Authors: Bezerra Lígia
Published: June 2018

In this article, I present Angolan writer José Eduardo Agualusa’s Nação crioula: A correspondência secreta de Fradique Mendes (1997) as a post-modern parody of the ctional character Fradique Mendes from Eça de Queirós’ A correspondência de Fradique Mendes (1900). Through parody, Agualusa creates historiographic metafiction meant to question the possibility of objective representations of reality, an issue central to post-modern aesthetics. I further propose that this questioning extends a discussion that is already suggested by Eça’s original text at the turn of the twentieth century, when concerns about the possibility of objective representations of reality also came to the fore.
Nitheroy, Revista Brasiliense (1836): A Political Bridge Between Rio de Janeiro, Paris, and Hispanic America
Authors: Lotufo Marcelo
Published: June 2018

Nitheroy: Revista Brasiliense de sciencias, lettras, e artes (Paris, 1836), is usually taken as the starting point of Brazil’s Romantic movement. The magazine, however, was primarily concerned not with literature but with the "modernization" of a recently independent Brazil. This essay focuses on the magazine in order to understand the role of literature in early nineteenth-century Brazilian politics. Approaching Brazilian Romanticism as inherently political serves to link nineteenth-century Brazilian literature to other Latin American literary movements of the period, and a re-examination of Nitheroy helps to bridge the gap that has historically separated Brazilian and other Latin American Romantic movements.
José da Silva Lisboa and the Pathology of Revolution
Authors: Monteiro Pedro Meira
Published: June 2018

Focusing on José da Silva Lisboa’s Constituição Moral e Deveres do Cidadão (1824/1825), this article explores how the image of Revolution, modeled on the "catastrophic" experiences of France and Haiti, projects itself onto the scenario of the nascent Brazilian empire. For Lisboa, the moralizing discourse should be capable of founding a new order in the tropics, of protecting "Brazilian youth" from the seduction of renovating principles, of maintaining well-tied the knots of a social fabric threatened by the madness of revolutionaries, who brought to the horizon of a young nation the danger of dissolution and corruption of the body politic.
Fetishism as Theatrical Device in Nelson Rodrigues's Os Sete Gatinhos
Authors: Grevan de Carvalho Isadora
Published: June 2018

In this essay, I examine the concept of fetish and how it manifests itself as Brazilian social structures in the theater of Nelson Rodrigues. I offer a particularly detailed study of fetish in Rodrigues’s Os Sete Gatinhos. Here fetish serves to illuminate gender relations and the patriarchal family as a cultural myth to be deconstructed, as well as working to reveal the connections between space, bodies, performativity, and power in Brazilian society.
Autobiographical Writings by Portuguese Emigrants in Newark: Glocal Emancipation and Resisting Stereotypes
Authors: Lechner Elsa
Published: June 2018

This article examines the experience of Portuguese immigrants in Newark, NJ (USA) through the analysis of autobiographical writings. It aims to highlight the heuristic value and social relevance of autobiographical writings by focusing on four Portuguese immigrants in Newark who self-published their life stories. I argue that autobiographical essays serve as a form of self-valued expression in defiance of the stereotypes that associate the Portuguese immigrant with low levels of education and a lack of interest in literature and culture in general. Finally, I underscore the contribution of biographical research in the emancipation of undervalued groups and individuals.
Russell Hamilton: Pioneering Critic of African Literatures in Portuguese
Authors: Arenas Fernando , Ferreira Ana Paula
Published: June 2018

Russell Hamilton’s scholarly career coincided with the anti-colonial liberation movements throughout the Portuguese African territories of Angola, Mozambique, Guinea-Bissau, Cape Verde, and São Tomé and Principe, in the 1960s and 70s. During this critical time-period, written literature in the form of poetry, short stories, essays, and novels played a major role among African elites by imagining these newly emerging nations. While denouncing the injustices and ravages of Portuguese colonialism, literary art galvanized readers to the cause of independence.
The New Generation
Authors: Machado de Assis Joaquim Maria , Newcomb Robert Patrick
Published: June 2018

“A Nova Geração,” published in December 1879 in the Revista Brasileira, is among the best-known and most substantive works of literary criticism written by Joaquim Maria Machado de Assis (1839-1908). Beyond its treatment of a heterogeneous group of mostly forgotten Brazilian poets, the essay’s interest lies in its articulation of ideas that would preoccupy Machado as a mature writer. This updated English translation makes this signature work available to new groups of readers.
'Conversações do Papel e Para o Papel': Ressonâncias Machadianas na Obra de Carlos Drummond de Andrade
Authors: Diego Marcelo
Published: June 2018

I this essay, I discuss the place of Machado de Assis within the Brazilian literary system by comparing and contrasting his work with that of Carlos Drummond de Andrade. In order to do so, I outline four types of dialogue between the two authors. The first is the profession of faith—the poem in which Drummond reveals Machado to be his literary addressee. The second is poetico-existential identification; that is, a commonality between the two regarding worldview, which gains form through an aesthetic conception. The third is a "resumption of paradigms," or the reoccurrence of images, techniques, and themes from Machado's fiction within Drummond's poetics. The fourth, finally, is the "resumption of syntagmata," the reoccurrence of textual quotations of or direct allusion to Machado's fiction in Drummond's poetics.
Invented Difference: On Inter-Culturality in Mouraria’s Mercado de Fusão
Authors: Iannone Catalina
Published: June 2018

In this article, I study the development of Mouraria’s Mercado de Fusão in the context of what I term "Invented Difference"—a marketing strategy that capitalizes on a utopist multiculturalism that lacks historicity and continuity—as a means by which to unpack how twenty-first-century multicultural space is produced in Lisbon, a rapidly changing city with a booming tourist economy. Through this lens, I analyze the market’s visual and material landscape—specifically its sculptures and food kiosks—to bring together questions regarding the mobilization of multiculturalism in urban redevelopment while taking into consideration the legacy of race relations in Portugal’s neoliberal present. I assert that the Mercado de Fusão project speaks to the broader ideological implications of tourist-centric development initiatives in Lisbon.

Joel Rufino dos Santos here provides a much-anticipated contribution to the study of the presence of Afro-Brazilians in the national theater. The author investigates the ways in which Afro-Brazilians are authors, characters, objects, and types—both onstage and off. In addition to offering an overview of the role of race in the history of Afro-Brazilian theater and drama, the book also contains many invaluable images that serve to illustrate as well as add insight to the written pages, filling a much-needed gap in critical studies of Brazilian theater.
Cabral, Amilcar. Resistance and Decolonization, translated and edited by Dan Wood, with an introduction by Reiland Rabaka, Rowman & Littlefield, 2016.
Authors: Peterson Charles
Published: June 2018

The heart of this book are the aspects of Cabral’s thought and work revealed in Wood’s translations. The leading voices of the tradition of Africana critical theory often wrote themselves out of their professional/disciplinary perspectives. This holds true for Cabral. In these pages, there are a series of lectures delivered by Cabral to the PAIGC cadres. As an agronomist for the Portuguese government, Cabral’s analysis of the possibilities of Guinean agrarian development was a factor in his commitment to a national liberation struggle. In this, we see the unique quality of Cabral’s thought, the dynamics of his role as commander, and glimpses into his character and humanity.
The Aquatic Woman: The Role of Water and the Feminine Divine in Mia Couto’s Terra Sonâmbula
Authors: Mitchell Maisha
Published: June 2018

Mia Couto's 1992 novel, Terra Sonâmbula, is known for its use of fantastic realism to convey the horrors of the Mozambican civil war and their effects. The supernatural invades the daily experience of the novel’s characters, and these move from the known world into a frequently aqueous and spiritual one. In this essay, I examine Couto's use of water, the supernatural, and the feminine and link these to African religious and cosmological origins. I see Couto's use of the black feminine aqueous divine as an alternate form of national history that gives voice to those who often go unheard in the chaos of war, particularly women and children.
The Paradigm at the Crossroads in the Middle of the Whirlwind: Arnold Schoenberg, João Guimarães Rosa, and the Animating Faust
Authors: Lewis Christopher T.
Published: June 2018

In the poem Dichtung und Wahrheit, Anthony Hecht explores the limits of representative art in the attempt to transcend the dichotomy between life and fixture, citing the need for a “Faust” to animate representation. Through the prism of cyberneticist Gregory Bateson’s theories on advanced levels of learning and controlling paradigm shifts, this article explores how the Austrian composer Arnold Schoenberg and the Brazilian writer João Guimarães Rosa both exemplify Hecht’s concept of an animating Faust. It juxtaposes Schoenberg’s twelve-tone method with Guimarães Rosa’s transrealism in their respective contexts, culminating in a comparison of the latter’s novel Grande sertão: veredas with the former’s opera Moses und Aron in order to show how they break out of the paradigms of their respective periods, transporting the reader/ listener to the unknowable place that Guimarães Rosa called the “third bank of the river.”

Authors: Sinnenberg Lauren , Mancheno Christina , Barg Frances K , Asch David A , Rivard Christy Lee , Horst-Martz Emma , Buttenheim Alison , Ungar Lyle , Merchant Raina
Published: June 2018

BACKGROUND

Widespread metaphors contribute to the public’s understanding of health. Prior work has characterized the metaphors used to describe cancer and AIDS. Less is known about the metaphors characterizing cardiovascular disease.

OBJECTIVE

The objective of our study was to characterize the metaphors that Twitter users employ in discussing hypertension and diabetes.

METHODS

We filtered approximately 10 billion tweets for keywords related to diabetes and hypertension. We coded a random subset of 5000 tweets for the presence of metaphor and the type of metaphor employed.

RESULTS

Among the 5000 tweets, we identified 797 (15.9%) about hypertension or diabetes that employed metaphors. When discussing the development of heart disease, Twitter users described the disease as a journey (n=202), as transmittable (n=116), as an object (n=49), or as being person-like (n=15). In discussing the experience of these diseases, some Twitter users employed war metaphors (n=101). Other users described the challenge to control their disease (n=34), the disease as an agent (n=58), or their bodies as machines (n=205).

CONCLUSIONS

Metaphors are used frequently by Twitter users in their discussion of hypertension and diabetes. These metaphors can help to guide communication between patients and providers to improve public health.
Factors Influencing Web-Based Survey Response for a Longitudinal Cohort of Young Women Born Between 1989 and 1995 (Preprint)
Authors: Loxton Deborah , Harris Melissa L , Forder Peta , Powers Jennifer , Townsend Natalie , Byles Julie , Mishra Gita
Published: June 2018

BACKGROUND

With health research practices shifting toward rapid recruitment of samples through the use of online approaches, little is known about the impact of these recruitment methods on continued participation in cohort studies.

OBJECTIVE

This study aimed to report on the retention of a cohort of young women who were recruited using an open recruitment strategy.

METHODS

Women from the 1989-95 cohort of the Australian Longitudinal Study on Women’s Health, recruited in 2012 and 2013 were followed up annually via Web-based surveys in 2014, 2015, and 2016. Prevalence ratios for survey response were calculated using log-binomial models with generalized estimating equations including demographic, health-related, and recruitment method characteristics examined as explanatory factors.

RESULTS

Of the 17,012 women who completed the baseline survey (Survey 1) in 2012 to 2013, approximately two-thirds completed Survey 2 (2014), and just over half completed Surveys 3 (2015) and 4 (2016). Women demonstrated transient patterns of responding with 38.21% (6501/17,012) of women completing all 4 surveys. Although retention of young women was associated with older age, higher education, higher self-rated health status, and low engagement with adverse health behaviors, the method of recruitment was a key determinant of study participation in the multivariate model. Although women were more likely to be recruited into the cohort via social media (eg, Facebook), retention over time was higher for women recruited through traditional media and referral approaches.

CONCLUSIONS

A balance must be obtained between achieving representativeness, achieving rapid cohort recruitment, and mitigating the pitfalls of attrition based on recruitment method in the new era of cohort studies, where traditional recruitment methods are no longer exclusively viable options.
Unraveling the Biopsychosocial Factors of Fatigue and Sleep Problems After Traumatic Brain Injury: Protocol for a Multicenter Longitudinal Cohort Study (Preprint)

Published: June 2018

BACKGROUND

Fatigue and sleep problems are common after a traumatic brain injury (TBI) and are experienced as highly distressing symptoms, playing a significant role in the recovery trajectory, and they can drastically impact the quality of life and societal participation of the patient and their family and friends. However, the etiology and development of these symptoms are still uncertain.

OBJECTIVE

The aim of this study is to examine the development of fatigue and sleep problems following moderate to severe TBI and to explore the changes in underlying biological (pain, brain damage), psychological (emotional state), and social (support family, participation) factors across time.

METHODS

This study is a longitudinal multicenter observational cohort study with 4 measurement points (3, 6, 12, and 18 months postinjury) including subjective questionnaires and cognitive tasks, preceded by 7 nights of actigraphy combined with a sleep diary. Recruitment of 137 moderate to severe TBI patients presenting at emergency and neurology departments or rehabilitation centers across the Netherlands is anticipated. The evolution of fatigue and sleep problems following TBI and their association with possible underlying biological (pain, brain damage), psychological (emotional state), and social (support family, participation) factors will be examined.

RESULTS

Recruitment of participants for this longitudinal cohort study started in October 2017, and the enrollment of participants is ongoing. The first results are expected at the end of 2020.

CONCLUSIONS

To the authors’ knowledge, this is the first study that examines the development of both post-TBI fatigue and sleep longitudinally within a biopsychosocial model in moderate to severe TBI using both subjective and objective measures. Identification of modifiable factors such as mood and psychosocial stressors may give direction to the development of interventions for fatigue and sleep problems post-TBI.

A critical analysis of intellectual capital research in universities
Authors: Bratianu Constantin
Published: June 2018

Researching on the intellectual capital in universities is a challenging task due to the complexity of the intellectual processes within any university and the fuzziness of the basic concepts and methodologies developed so far. Universities are among the oldest social institutions and they concentrate high densities of intellectual capital. The concept of intellectual capital has been created as a result of increasing significantly the role of intangibles in economy and of the dramatic split between the book value and market value of the new companies based on intensive knowledge processes. Intellectual capital represents that component of the total capital of any organization which incorporates all intangible resources and their transformations. Intellectual capital is highly nonlinear by comparison with the capital containing tangible resources, which has a linear structure and Newtonian dynamics. The canonical structure of the intellectual capital is composed of human capital, structural capital, and relationship capital. This structural model has been used extensively in evaluating and reporting the intellectual capital of organizations, including universities. However, the Newtonian paradigm constitutes an important limitation in understanding properly both the nature of intellectual capital and how to manage it efficiently. Our research question is focused on how we can change that paradigm with a better one able to represents more adequately the nature and the basic structure of the intellectual capital. The methodology we used is based on in depth literature analysis, metaphorical thinking, critical thinking, and the multifield theory of knowledge. As a result of our research, this paper presents a new approach of the intellectual capital and its application to the universities.
A pragmatic view on the financial theories
Authors: Chișu Mihai
Published: June 2018

This presentation reviews some real examples from a trading daily basis behavior proving the sentiment is one of the most important drivers when it comes to investment decision. During decades of studying and observing the financial markets we have seen different approaches in the light of many prestigious writers. Are we rational enough to be good candidates for Fama’s theory of Efficient Market Hypothesis? Is it true what John Maynard Keynes stated 90 years ago when he said „the market is subject to waves of optimistic and pessimistic sentiment”? Is the financial behavior the new trend in the financial markets? Are Daniel Kahneman (Nobel Prize winner 2002) and Amos Tversky the new challengers in the market theories league? Future research should concentrate on various symptoms of sentiment and what makes investors become prone to sentiment. This is an important issue to be debated since investors constantly have to analyze, process and interpret huge data of information which provides the basis for their actions.

Adoption of Circular Economy concepts and practices by Portuguese Citizens and Companies
Authors: Fonseca Luis Miguel , Domingues José Pedro
Published: June 2018

The concept of Circular Economy is an emerging topic and the European Union has established a European Circular Economy Strategy in 2015. Although this concept originates from Europe, there is also an increased attention to the Circular Economy in China and the country has implemented regulatory controls in that regard. The scientific interest on this issue has been increasing and a great deal of research articles has been published in the soundest scientific journals recently. The concept of Circular Economy aims to address the need to pursue economic growth, while protecting the environment (including existing resource limitations and pollution prevention), and paying attention to societal and people needs and expectations. The adoption of Circular Economy can generate considerable tangible and intangible benefits such as new opportunities for co-operation, access to markets and innovation of products and services and, simultaneously, improving the environmental performance and mitigating the risks of resource scarcity. This creates value for the companies and their stakeholders and contributes to enduring success. To assess if the Portuguese citizens and companies support and adopt a “Circular Economy behavior”, an online survey was carried out amongst ISEP - P. Porto population, yielding more than 200 valid responses (65% of the total responses were provided by students). Based on the survey outputs (assessment supported in a 5 point Likert type scale), the following conclusions can be drawn: Most respondents agree that it is beneficial both for the environment and the economy the adoption of production systems based on used products and parts reuse and recycling; There is also agreement that the selective collection of waste should be the base to develop new products and there is significant support for a “zero waste economy” in which all used products or materials are reused or recycled. However, the respondents consider that the Portuguese citizens do not always segregate and deposit their waste in the appropriate waste containers and the same applies to companies that do not segregate and manage their waste adopting a systematically environmentally responsible approach. Moreover, they consider that the Portuguese legislation only mildly supports the adoption, both from citizens and companies, of environmental friendly practices. These conclusions reinforce the need to strengthen Circular Economy concepts and approaches within the Portuguese government, citizens, and companies.

The research purpose is to present the possibilities of the human being which are useful in order to improve the personal level of energy and to achieve an increased balance and a strong self control. These are the necessary conditions to be performed and in the same time to maintain a good health. Humans usually use energy from external sources. But, first of all, by employing different personal techniques, one can reach a high level of balance, energy and self control. These are the simplest, the fastest, the most efficient, the most economical and also ecological ways to have energy. If these attempts are efficient, you are first of all warm, then less ill and stressed. Everybody should try these kinds of methods first. A comparison was made between the results from two consecutive years, obtained by measuring the subject using a Bio-Well device. It results an increase of 23% in the energy level, in the conditions that the other parameters are optimal. The general balance reached the value of 99.97%. The authors proved, with the occasion of these original measurements, that a perfect balance can be reached. Another set of original and new measurements reveal the possibility of the human being to have a good self control. The subject proposed and succeeded in moving the second body energy centre by his own will, which is the most important energy centre of the body in the Zen-Buddhism. This is a remarkable completely original result obtained, maybe, for the first time in the world. In principle, we could control then the positions of the all seven energy centers, one by one. And so, the whole balance of the body. Also, in this way an incredible personal control and level of performance and also a high level of happiness can be achieved.
Innovation needs deregulation: the case of taxi and private hire companies
Authors: Nasulea Christian , Nasulea Diana Florentina , Mic Stelian Mihai
Published: June 2018

Every year seems to bring about new technologies that radically change the way we do things. New innovative business models come to life, that change the way the world works so much that a shift of mindset is required if we are to keep up. These days, the largest transport company in the world owns no cars, the largest accommodation provider owns no real estate, the largest retailer by value has no inventory of its own, and the most popular media owner creates no content. But what about the role of regulation in this brave new world? We take a look at the rivals, taxi companies and private hire transport companies (in particular Uber), to assess the need for regulation and the impact of regulation on these two contenders. Our research examines the effects of said regulation on service quality and safety, correlated with consumer opinion data. The impact of non-regulatory incentives on the two seemingly-opposed business models is discussed, thus making the logical case for increased deregulation of both taxis and private hire companies. Opening the way to innovative companies and innovative new business models, allowing them to change the world is our gateway to growth, prosperity and sustainability.
