A MULTIPLICAÇÃO INCESSANTE DO VALOR: A DIFERENÇA ENTRE ENTESOURADOR E CAPITALISTA EM MARX
Authors: Tabosa Adriana Santos
Published: June 2019

A proposta deste artigo é analisar a distinção estabelecida por Marx entre“entesourador” e “capitalista”. Levanta-se como hipótese que o fundamento dessa diferença reside na finalidade da multiplicação incessante do valor para ambos. Tanto o entesourador quanto o capitalista agem por um impulso pelo enriquecimento. Contudo, o entesourador acumula dinheiro como dinheiro, ao passo que o capitalista acumula dinheiro como capital. Enquanto o entesourador retém o dinheiro da circulação, o capitalista empenha-se em fazer o dinheiro circular, indefinidamente. Não obstante, parte-se do princípio que essa multiplicação incessante do valor praticada por um e outro possui causas distintas. Do ponto de vista psicológico, o entesourador ama o dinheiro em seu perpétuo estado de potência. O capitalista tem por móbil a valorização do valor como uma finalidade em si mesma. O movimento insaciável do capital é um reflexo da sua própria cupidez.

Gastric adenocarcinoma cells secrete sulfomucins, but their role in gastric tumorigenesis remains unclear. To address that question, we generated A4gnt/ Chst4 double-knockout (DKO) mice by crossing A4gnt knockout (KO) mice, which spontaneously develop gastric adenocarcinoma, with Chst4 KO mice, which are deficient in the sulfotransferase GlcNAc6ST-2. A4gnt/ Chst4 DKO mice lack gastric sulfomucins but developed gastric adenocarcinoma. Unexpectedly, severe gastric erosion occurred in A4gnt/ Chst4 DKO mice at as early as 3 weeks of age, and with aging these lesions were accompanied by gastritis cystica profunda (GCP). Cxcl1, Cxcl5, Ccl2, and Cxcr2 transcripts in gastric mucosa of 5-week-old A4gnt/ Chst4 DKO mice exhibiting both hyperplasia and severe erosion were significantly upregulated relative to age-matched A4gnt KO mice, which showed hyperplasia alone. However, upregulation of these genes disappeared in 50-week-old A4gnt/ Chst4 DKO mice exhibiting high-grade dysplasia/adenocarcinoma and GCP. Moreover, Cxcl1 and Cxcr2 were downregulated in A4gnt/ Chst4 DKO mice relative to age-matched A4gnt KO mice exhibiting adenocarcinoma alone. These combined results indicate that the presence of sulfomucins prevents severe gastric erosion followed by GCP in A4gnt KO mice by transiently regulating a set of inflammation-related genes, Cxcl1, Cxcl5, Ccl2, and Cxcr2 at 5 weeks of age, although sulfomucins were not directly associated with gastric cancer development:

Connected learning journeys in music production education
Authors: Toulson Rob , Hepworth-Sawyer Russ
Published: June 2019

The field of music production education is a challenging one, exploring multiple creative, technical and entrepreneurial disciplines, including music composition, performance electronics, acoustics, musicology, project management and psychology. As a result, students take multiple ‘learning journeys’ on their pathway towards becoming autonomous learners. This article uniquely evaluates the journey of climbing Bloom’s cognitive domain in the field of music production and gives specific examples that validate teaching music production in higher education through multiple, connected ascents of the framework. Owing to the practical nature of music production, Kolb’s Experiential Learning Model is also considered as a recurring function that is necessary for climbing Bloom’s domain, in order to ensure that learners are equipped for employability and entrepreneurship on graduation. The authors’ own experiences of higher education course delivery, design and development are also reflected upon with reference to music production pathways at both the University of Westminster (London, United Kingdom) and York St John University (York, United Kingdom).
Studio Trad: Facilitating traditional music experiences for music production students1
Authors: Kearney Daithí , Commins Adèle
Published: June 2019

Many music production programmes in higher education institutions are heavily invested in popular music genres and production values in contrast to the diversity of musics often included in other music programmes and encountered in everyday life. Commenting on his 2017 album, Ed Sheeran highlights the potential for incorporating Irish traditional music into popular music. Over the past number of years, creative practice research projects at Dundalk Institute of Technology have provided opportunities for music production students to engage in the recording and production of Irish traditional music, broadening their experience beyond popular music genres and facilitating time for them to work collaboratively with Irish traditional musicians. Thus, an authentic and action-oriented mode of engagement in higher education is utilized to enhance the learning experience continuously aware of changes and attitudes in the music industry. This article focuses on three Summer Undergraduate Research Projects that provided students with the opportunity to research and record Irish traditional music during the summer months. The project not only provided the students with credible industry-like experience, it also provided the staff involved with an insight into the potential of collaborative project work to address multiple learning aims and objectives. In this article, a critical review of the projects is informed by feedback from the students involved, which can inform future development and structures of existing programmes in music production education.
Flying Solo: Elevating student sound engineers into responsible work-experience roles at live music events
Authors: Carugo David
Published: June 2019

The role of live sound mixer is somewhat akin to piloting an aeroplane full of passengers: you are in control of the outcome for a number of people for a certain time, and must take in a lot of sensory information, process and act upon it using highly technical controls and equipment. Work-experience students at live events often work up to this role and have to undertake more menial tasks such as running cables, moving loudspeakers and other equipment, loading vans and trucks; even on a long-term placement. However, by taking the lead from pilot training where the learner takes the controls under supervision of a more experienced professional pilot, student sound engineers can assume control of a live mix with an audience present while benefitting from the guidance of a professional. This article discusses such an approach in the context of its place within or alongside the curriculum.
¿Por qué lo llaman vida cuando quieren decir arquitectura?...o viceversa
Authors: Capdevila Castellanos Iván
Published: June 2019

Artefactos, “cacharros”, dispositivos, ensamblajes y otras construcciones de estética aparentemente indeterminada o inacabada pueblan cada vez más la escena arquitectónica contemporánea. Éstos se alimentan, en muchas ocasiones, de un imaginario no propiamente arquitectónico mediante la reapropiación de objetos provenientes del mundo industrial, agrícola, etc. como medio para figurar una nueva vida más justa, inclusiva, concienciada políticamente, crítica y, sobre todo, a través de la cual humanos –y no humanos- puedan expresarse subjetivamente. Este artículo plantea, precisamente, una reflexión abierta sobre la relación entre esta “nueva” estética y esta nueva ética revisitando sus antecedentes ideológicos encarnados en el trabajo de Cedric Price y Peter Cook. Tanto el Fun Palacecomo la Plug-In Citypueden considerarse trabajos que se alejan de los estándares y convenciones arquitectónicas del momento para formalizar una nueva y necesaria aproximación al hecho arquitectónico, entendido éste como un posibilitador de situaciones inciertas e imprevisibles; esto es, la vida en sí misma. Ahora bien, ¿cuál es la arquitectura que está detrás de estas propuestas? ¿Sus dibujos presentan la descripción de un problema o el principio de su solución? ¿Esos objetos figurados simplemente restituyen algún aspecto de la realidad o verdaderamente proponen las pautas para su transformación? Todas estas son preguntas de extrema vigencia y, por tanto, pertinencia. El artículo, así, y a través del estudio de la peculiar relación entre Price y Cook, se plantea indagar en todas estas cuestiones pasadas con el objetivo claro de arrojar algo de luz crítica al momento presente.

Quantitation of the arginine family amino acids in the blood of full-term infants perinatally in relation to their birth weight
Authors: Manta-Vogli Penelope D. , Schulpis Kleopatra H. , Loukas Yannis L. , Dotsikas Yannis
Published: June 2019

Background

Arginine family amino acids (AFAAs) include glutamine (Gln) plus glutamate (Glu), ornithine (Orn), proline (Pro), citrulline (Cit) and arginine (Arg). We aimed to quantitate these amino acids in the blood of full-term infants in relation to their birth weight (BW) perinatally.

Methods

Breastfeeding full-term infants (n = 2000, 1000 males, 1000 females) with a BW of 2000–4000 g were divided into four equal groups: group A, 2000–2500 g; B, 2500–3000 g; C, 3000–3500 g and D, 3500–4000 g. Blood samples as dried blood spots (DBS) were collected on the third day of life and analyzed via a liquid chromatography tandem mass spectrometry (LC-MS/MS) protocol.

Results

Gln plus Glu mean values were found to be statistically significantly different between males and females in all studied groups. The highest values of these amino acids were detected in both males and females in group D. Orn mean values were found to be statistically significantly different between males and females of the same BW in all groups except the last one. The lower mean value was determined in group A, whereas the highest was determined in group D. Cit and Arg mean values were determined to be almost similar in all studied groups.

Conclusions

Gln plus Glu and Orn blood concentrations were directly related to infants’ BW. Conversely, Cit and Arg did not vary significantly in all groups.
Is Divorce a Solution? Decentralization Effect on Economic Growth in Post-Civil Conflict Countries
Authors: Hamati Samer
Published: June 2019

Civil conflict is the nation’s most important historical event, and it became more frequent in countries already emerged from previous conflicts. High economic growth, as well as other institutional procedures, is key to break this conflict trap. Thus, the current article explores the role decentralization may play to enhance economic growth in post-civil conflict countries. In order to avoid untrue peaceful cases, the article adopted a strict criterion of post-conflict periods, leading to a small dataset. Distinguishing between two forms of decentralization and using two equations with different techniques, the article finds a hampering effect of fiscal decentralization on economic growth in countries emerging from civil conflicts, while it finds insignificant mixed effects of political decentralization. These findings support the distinction made between the real de facto decentralization and the official de jure one. They validate the belief that although central authorities in many countries pretend to apply decentralization, they limit its effectiveness by some legal procedures creating “fake” decentralization.
The Wax and the River Metaphors in Ovid’s Speech of Pythagoras and Plato’sTheaetetus
Authors: Kelly Peter
Published: June 2019

In the Speech of Pythagoras fromMetamorphoses15, Ovid uses a metaphor of how wax can be stamped with new images to illustrate how theanimacan remain substantially the same while altering in shape when undergoing transmigration. Shortly after he describes how all things are in a state of flux, and compares the flow of time to the movement of a river. In Plato’sTheaetetus, Socrates, in an extended analogy, tells us to imagine that the ψυχή contains a block of wax, upon which are imprinted our memories, while the dialogue also contains a lengthy criticism of the Heraclitean doctrine of flux. This article will argue that Ovid adapts the wax-metaphor from theTheaetetusand that the dialogue also provides the context for Ovid’s allusion to the Heraclitean principle that πάντα ῥεῖ. It will analyse how the wax and river metaphors were transformed in the epistemological theories of the Stoics and the Epicureans in order to demonstrate how Ovid reformulates this series of philosophical discussions for poetic purposes. The final part of this article will discuss how the wax and river metaphors can be read in term of the wider intertextual agenda of the Speech of Pythagoras.
The effect of surface modification of PMMA/chitosan composites on improving adsorption properties for chelating Pb2+
Authors: Dai Xin , Zhang Xiaohang , Wang Zhenxi , Xu Sheng , Zhang Shangxi , Cao Meng , Jiang Xinde
Published: June 2019

As lead-containing products, such as lead batteries, are widely used, water pollution problems caused by Pb2+ show a significant threat to the ecosystem and human health. To overcome this serious problem, the modified poly(methyl methacrylate) (PMMA)/chitosan (CS) composites were prepared by adding CS into the PMMA matrix as functional filler and surface modification. The structure, thermal stability, size, morphology and adsorption properties of the modified PMMA/CS composites were characterized by Fourier transform infrared spectroscopy, thermogravimetric analysis, scanning electron microscopy, and inductively coupled plasma optical atomic emission spectrometry. The results indicated that the modified PMMA/CS composites had a uniform size of about 1 μm and showed quite good thermal stability. In addition, the Pb2+ removal of the modified PMMA/CS composite reached up to 98% when the initial Pb2+ concentrations are under 100 mg l−1. The results of the adsorption isotherms indicated that the Langmuir isotherm fits best to the experimental data when compared with the Freundlich isotherm and Temkin isotherm. All these results demonstrate that modified PMMA/CS has a good adsorption property and can be a promising adsorbent for chelating Pb2+.

Published: June 2019

Because of high mobility, the immobilization of long-lived fission product 79Se (often existed as 79Se(IV) and 79Se(VI) anions) is a critical consideration in the repository of high-level radioactive waste. In this work, a Fe-OOH modified bentonite (Fe-OOH-bent) was synthesized as a potential filling material in the repository site for effective adsorption and present the migration of different species of 79Se. The adsorbent was characterized using FT-IR, XRD, XFS, zeta potential and BET to clarify its physical properties, compositions and structures. A good thermal and radiation stabilities of Fe-OOH-bent was confirmed by its stable uptake ratio for Se(IV) and Se(VI) compared to original samples. The batch experimental results show that Se(IV) and Se(VI) can be efficiently removed from aqueous by Fe-OOH-bent within 60 min with maximum adsorption capacities of 68.45 mg/g for Se(IV) and 40.47 mg/g for Se(VI) in the optimal conditions, indicating its high potential application in consideration of its simple synthesis process, low cost and high adsorption capacity in view of immobilization of 79Se. The surface species and variation of oxide state of Fe as well as Se(IV) and Se(VI) onto Fe-OOH-bent were investigated by XPS analysis. The values of relative area of Se(IV)–O and Se(VI)–O in XPS spectra followed the same tendency as their adsorption ratio with the variation of system pH, suggesting that the formation of complexes between selenium species and Fe-OOH-bent surface.
Diagnostic values of neutrophil/lymphocyte ratio, platelet/lymphocyte ratio and procalcitonin in early diagnosis of bacteremia
Authors: Colak Ayfer , Aksit Merve Zeytinli , Toprak Burak , Yılmaz Nisel
Published: June 2019

Objective

The aim of this study is to investigate the diagnostic accuracy of complete blood count (CBC), C-reactive protein (CRP), and procalcitonin (PCT) levels, which can be used as a cultural alternative for the diagnosis of infection faster.

Methods

The patients were divided into two groups as bacteremia (n = 220) and nonbacteremia group (n = 812). The bacteremia group was divided into two subgroups as Gram-positive bacteria (n = 167) and Gram-negative bacteria (n = 53).

Results

PCT, CRP, red blood cell distribution width (RDW), platelet distribution width (PDW), neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR), and mean platelet volume (MPV) levels were significantly higher in patients with positive blood culture than non-patients. The serum PCT levels were 3.80 (0.83–37.68) and 0.43 (0.16–2.61) ng/mL, respectively (p < 0.001) in the patients with Gram-negative and Gram-positive bacterium. PCT at a cut-off value of 0.45 ng/mL for Gram-negative bacterium; sensitivity of 90% and specificity of 64%.

Conclusions

It is important that RDW, PDW, NLR, PLR, MPV values can be measured quickly, easily and cheaply by automatic hematological analysis. However, among the markers tested, PCT has the best diagnostic performance for Gram-negative bacteremia.

Electrical Conductivity of Zirconium Tetrachloride Solutions in Molten Sodium, Potassium and Cesium Chlorides
Authors: Salyulev Alexander B. , Potapov Alexei M.
Published: June 2019

The electrical conductivities of the MCl-ZrCl4 (M = Na, K, Cs) melts at the ZrCl4 concentration of <33 mol.% were studied within the range of concentrations and temperatures at which the vapor pressure above the melt is <1 atm. Such melts are of interest for industrial use. The conductivities of the molten KCl-ZrCl4 (10–25 mol.% ZrCl4) and CsCl-ZrCl4 (10–30 mol.% ZrCl4) solutions were measured for the first time. The data on the conductivities of the NaCl-ZrCl4 melts with the ZrCl4 concentration ranging from 10.5 to 25.5 mol.% were refined. In all cases studied, results showed that the conductivity of the melts increased as the temperature increased and that the conductivity of the melts decreased as the concentration of ZrCl4 increased. The same tendency was observed in a series of NaCl-ZrCl4, KCl-ZrCl4 and CsCl-ZrCl4 melts.
When Your Boo Becomes a Ghost: The Association Between Breakup Strategy and Breakup Role in Experiences of Relationship Dissolution
Authors: Koessler Rebecca B. , Kohut Taylor , Campbell Lorne
Published: June 2019

Ghosting, or avoiding technologically-mediated contact with a partner instead of providing an explanation for a breakup, has emerged as a relatively new breakup strategy in modern romantic relationships. The current study investigated differences in the process of relationship dissolution and post-breakup outcomes as a function of breakup role (disengager or recipient) and breakup strategy (ghosting or direct conversation) using a cross-validation design. A large sample of participants who recently experienced a breakup was collected and randomly split into two halves. Exploratory analyses were conducted in Sample A and used to inform the construction of specific hypotheses which were pre-registered and tested in Sample B. Analyses indicated relationships that ended through ghosting were shorter and characterized by lower commitment than relationships that ended directly. Recipients experienced greater distress and negative affect than disengagers, and ghosting disengagers reported less distress than direct disengagers. Ghosting breakups were characterized by greater use of avoidance/withdrawal anddistant/mediated communication breakup tactics and lessopen confrontation and positive tone/self-blame breakup tactics. Distinct differences between ghosting and direct strategies suggest developments in technology have influenced traditional processes of relationship dissolution.
NICE targeted screening to identify gestational diabetes: who are we missing?
Authors: Kucuk Canel , Chakera Ali J , Macaninch Elaine
Published: June 2019

Background: Women with gestational diabetes (GDM) are at increased risk of perinatal complications. NICE currently recommends targeted screening of high-risk pregnant women. Our hospital’s diagnostic pathway for GDM has changed from universal screening (glucose challenge test followed by oral glucose tolerance test) to NICE-recommended targeted screening.Aims: We investigated whether women who would be missed by a targeted screening protocol had adverse clinical outcomes.Methods: We reviewed the electronic records of all women with GDM who delivered between April and October 2016, during a period of universal screening. Treatment and birth outcomes were compared between those with NICE risk factors (RF) and those with no risk factors (NoRF). Differences were assessed using χ2 tests.Results: 92 women with GDM gave birth during the six months studied. 32 (35%) had no risk factors and would not currently be diagnosed with GDM. There was a significant difference in treatment between the NoRF and RF groups (p=0.003). More women in the NoRF group were managed on diet and exercise alone (53% vs. 40%) and fewer NoRF women required insulin therapy (19% vs. 45%). Delivery events were similar in the two groups (p=0.23). Fewer women in the NoRF group had macrosomia (birth weight >4000 g) (NoRF n=1 (3.1%) vs. RF n=5 (8.3%)). Admissions to the special care baby unit, predominantly for neonatal hypoglycaemia (capillary blood glucose <2.2 mmol/L), were greater in the NoRF group (NoRF n=7 (21.9%) vs. RF n=5 (8.3%)). No stillbirths or shoulder dystocia occurred in either group.Conclusions: Targeted screening for GDM using NICE guidelines would have missed over a third of women with GDM. Although women in the NoRF group required less pharmacological treatment, they had adverse maternal and fetal outcomes equivalent to those of women with RF. Our results support universal screening of GDM.
Remission of type 2 diabetes: a position statement from the Association of British Clinical Diabetologists (ABCD) and the Primary Care Diabetes Society (PCDS)
Authors: Nagi Dinesh , Hambling Clare , Taylor Roy
Published: June 2019

This joint Association of British Clinical Diabetologists (ABCD) and the Primary Care Diabetes Society (PCDS) position statement reviews the current evidence related to remission of type 2 diabetes. We believe that there is ample evidence to support the statement that it is possible to achieve remission in type 2 diabetes. In putting this document together, both societies recognise that this is an area of huge clinical significance and has suggested a pragmatic definition of type 2 diabetes and the importance of the proposed definition for clinicians in primary care. This proposal makes firm recommendations about the importance of life style and weight loss in achieving remission of type 2 diabetes and also recognises the different strategies that can be used to achieve remission of type 2 diabetes; however, most of these involve sustained weight loss. This is particularly true in the early stages of type 2 diabetes when irreversible damage to the beta cell has not happened. A further recommendation is that the term ‘remission’ of type 2 diabetes should be used in preference to other previous terms such as ‘diabetes resolved’, and should be used for the purpose of clinical coding. It is of key importance that, in those individuals who achieve and sustain remission, robust systems are in place to call and recall these individuals for annual review and that primary care is adequately resourced to facilitate this. Finally, we urge the national and international diabetes societies to work together in further refining the proposed definition as new evidence emerges based on ongoing research.
Modelling and simulation of mitral valve for transapical repair applications
Authors: Gaidulis Gediminas , Selmi Matteo , Zakarkaitė Diana , Aidietis Audrius , Kačianauskas Rimantas
Published: June 2019

Development and application of the numerical model for the simulation of human heart mitral valve (MV) transapical repair is presented. Transapical repair with neochordae implantation is a novel surgical technique allowing beating-heart correction of mitral regurgitation caused by chordae tendineae rupture through a minimally-invasive approach. In the present study, the structural finite element model of the MV decoupled from the blood flow is considered. It comprises two leaflets and chordae tendineae described by nonlinear material model. Geometry of the model and kinematic boundary conditions for fixed points of MV annulus, papillary muscles, and left ventricle apex are defined by patient-specific data. Decoupled behavior of blood is specified by the time-dependent physiologic transvalvular pressure.
Personalized computational modelling strategy is applied to perform virtual transapical MV repair by positioning neochordae following the real-life surgery procedure executed by surgeons. A transient analysis in time frame between end-diastole and peak systole is conducted to evaluate post-repair MV function. Computational MV simulation and modelling results provide quantitative information about the neochordae contribution to the MV function improvement and present practical value for the surgical planning of transapical MV repair.

Authors: Kamali M. , Ahmadi J. , Naeimi S. , Guo D.
Published: June 2019

Fusarium wilt of tomato is one of the most prevalent and
economically important diseases of tomato worldwide especially in tropical
regions. The aims of the present study were to isolate and characterize
Bacillus bacteria from tomato rhizospheric soil of various
regions in Iran and determine the isolates that exhibit high levels of
antagonistic efficiency against tomato Fusarium wilt pathogen,
Fusarium oxysporum f. sp. lycopersici
(Fol) and growth promotion activity. In this study, 303
Bacillus isolates were obtained from tomato rhizospheric
soil. Dual culture and volatile metabolite tests were used to screen for
antagonism of Bacillus isolates against Fol.
Among them, 20 isolates were found to inhibit pathogen growth by 67.77% and
33.33% in dual culture and volatile metabolite tests, respectively. Based on the
results of physiological tests and 16S rRNA and gyrA gene
sequence analysis of 20 effective isolates, 11, seven and two isolates were
identified as B. subtilis, B. velezensis and
B. cereus, respectively. The results of greenhouse
assessment showed that KR1-2, KR2-7 and A2-9 isolates which were characterized
as Bacillus subtilis, reduced the disease index to 16.67% and
promoted the plant growth by 80%. These isolates may serve as potential
promising biocontrol agents against Fusarium wilt of
tomato.

In recent years, functional foods and bioactive components in foods have
drawn a lot of attention as well as interest of food scientists, nutritionists, health professionals, and consumers. The advent of this new food category has been facilitated by increasing scientific knowledge about the metabolic and genomic effects of diet and specific dietary components on human health. The relationship between health and diet is well known and it is a main key for prevention of variety of diseases. Milk is considered as a very good source of bioactive components and it has been known to contain macro- as well as micronutrients of high nutritional and therapeutic value. Also, bioactive components have been exploited from milk and dairy products for application in functional foods and for potential pharmaceutical use. Biologically active compounds guard neonates and adults against pathogens and illnesses. Some major bioactive components of milk are derived from caseins, whey proteins, lipids, lactoferrine, vitamins, immunoglobulins and growth factors. The aim of this paper was to provide
an overview and explain the health effects of already known and recently detected bioactive components derived from bovine milk on humans.
PARTISIPASI POLITIK WANITA INDONESIA DI PARLEMEN DAN RELEVANSINYA DENGAN PANDANGAN ULAMA TENTANG PERAN WANITA DALAM POLITIK
Authors: Nuraeni Neni
Published: June 2019

AbstrakKeterwakilan perempuan di Parlemen tidak memenuhi kuota batas minimal yang ditetapkan undang-undang, yaitu 30 %. Tulisan ini menelusuri faktor-faktor yang menjadi ken­dalanya. Hal lain yang juga dikaji adalah upaya-upaya sistematis yang dilakukan partai politik dalam mempersiapkan pemenuhan kuota perempuan dan mengaitkan semua permasalahan ini dengan fikih legislatif perempuan yang dikemukakan ulama yang diduga memiliki peran dan pengaruh dalam persoalan ini. Adanya anggapan bahwa dunia politik adalah dunianya laki-laki merupakan salah satu faktor kendalanya. Oleh karenanya perlu upaya sistematis yang perlu dilakukan partai politik dalam memper­siapkan pemenuhan kuota perempuan. Pandangan ulama tentang kedudukan politik kaum wanita memiliki relevansi yang signifikan terkait dengan partisipasi politik perempuan di parlemen, baik relevansi yang bersifat mendukung, maupun yang bersifat menghambat atau menjadi kendala, khususnya bagi partai yang berasas Islam atau berbasis umat Islam.Kata Kunci: Fikih Legislatif, Kuota Perempuan di Parlemen, Politik
PARLIAMENTARY DAN PRESIDENTIAL THRESHOLD: DALAM OTOKRITIK POLITIK ISLAM KONTEMPORER
Authors: Rizal Lutfi Fahrul
Published: June 2019

AbstrakPartai politik merupakan salah satu lembaga penting yang memiliki peranan dan fungsi strategis dalam keberlangsungan kegiatan perpo­litikan di Indonesia. Terlebih lagi pasca dibukanya “kran” reformasi yang memberikan kebebasan dan kemudahan bagi masyarakat untuk menggagas dan membentuk sebuah partai politik. Akan tetapi, dengan dibukanya ruang tersebut semakin memberikan peluang akan terben­tuknya paham primodialisme sempit yang justru lebih mengedepankan kepentingan sekelompok atau segelintir orang, ketimbang harus me­mi­kirkan kepentingan bersama dan tentunya akan mempengaruhi rasa per­satuan dan kesatuan yang termaktub pada sila ke-3. Political thres­hold selama ini dianggap sukses sebagai langkah upaya penye­derhanaan keberadaan multi partai politik di Indonesia secara alami dan normatif. Namun, dalam penyelenggaraannya seringkali dilakukan cenderung ti­dak berorientasi pada kemaslahatan umum (public oriented), terutama oleh kelompok pemenang pada saat ini. Padahal, kajian politik Islam kontemporer memiliki perinsip dengan kaidah tasharruful imami ‘ala ro’iyyatihi manutun bi al-maslahat, yang berarti bahwa segala kebijakan atau keputusan yang dibuat oleh pemimpin haruslah sarat dengan nilai kemaslahatan bersama demi terbentuknya masyarakat madani dan baldan thayyibah.Kata kunci: Political Threshold, Politik Islam, Partai Politik
INSTRUMENT PAJAK DALAM KEBIJAKAN FISKAL PERSPEKTIF EKONOMI ISLAM (Tinjauan Kritis Terhadap Penerimaan Perpajakan dalam RAPBN 2017)
Authors: Al Hasan Fahdil Amin , Iman Rifqi Qowiyul
Published: June 2019

AbstrakPajak merupakan instrumen utama dalam RAPBN 2017, ia mendominasi diantara semua instrumen pendapatan negara. Dalam RAPBN 2017, penerimaan pajak ditargetkan sebesar Rp. 1.495.893,8 miliar atau sebesar 86,15 persen dari target pendapatan negara yang diperkirakan dapat mencapai Rp. 1.737.629,4 miliar. Menyoroti dominasi pajak, lambat laun itu akan berpotensi mendatangkan kendala pada suatu saat nanti. Oleh karenanya diper­luakan kajian agar penerimaan negara tidak hanya didapatkan melalui pajak. Dalam Islam, penerimaan negara tidak hanya didapatkan melalui pajak, namun terdapat istrumen lain yang dapat digunakan sebagai bentuk penerimaan negara. Tujuan dari pene­litian ini adalah untuk menganalisis pajak sebagai sumber pendapatan negara dari perspektif ekonomi Islam dengan memperhatikan RAPBN 2017. Penelitian ini mengguna­kan teknik kualitatif deskriptif dengan teknik content analysis. Hasil yang didapat pada penelitian ini bahwa pajak dalam artian dharibah bukan merupakan instrumen utama dalam pendapatan negara, namun ia dikenakan jikan instrumen utama lainnya tidak mencukupi negara dalam menjalankan roda pemerintahannya.

Beginning in the late eighteenth century and through reconstruction following the Mexican Revolution, state officials have attempted to construct the futures of residents of Amapa, a town founded by black runaway slaves. The article discusses how past and present townspeople have created and practiced distinct temporalities, incorporating the often-failed material and political potentials that were imagined for them.
Should Archaeology Have a Future?
Authors: Wurst LouAnn
Published: June 2019

Archaeologists have recently been discussing what the future may hold for archaeology, a focus firmly situated within the context that the discipline of archaeology is authentic and legitimate and deserves to have a future. In this paper, I want to challenge these ideas and think instead about whether archaeology should even have a future. This line of reasoning is developed by examining the relationship between capitalism and the academy, neoliberal transformations to higher education, and some of the ways that archaeologists have responded. I conclude with some suggestions for alternatives, both for those working within the dominant capitalist academic structures themselves and those that eschew capitalism itself.
History, Capitalism, and Postcolonial Identities
Authors: Benavides O. Hugo
Published: June 2019

In the last four decades there have been critical interventions in archaeology that have engaged the issues of politics, class, and colonialism within the production of the past. A concern in this endeavor has been the role that time has played in the chronological ordering of historical narratives. This article contributes to these debates by assessing narratives of archaeologies of the future, particularly as they have been expressed in Western science-fiction and dystopic texts, focusing in particular on Christopher Priest’s The Affirmation (1981) and Roberto Bolaño’s 2666 (2004, English translation 2009). It assesses how one accounts for such a pernicious system of exploitation as capitalism to have been historicized into a global paradigm, and the complicit role that archaeology plays in this narrative production.
Gestão de Mídias Sociais: Um estudo exploratório com os grandes bancos brasileiros.
Authors: Jonas Luiz Sergio Vieira , Streit Rosalvo Ermes
Published: June 2019

O presente artigo tem por objetivo a investigação do atual estado da gestão das mídias sociais pelos grandes bancos brasileiros. As mídias sociais constituem-se de um grupo de aplicações baseadas em internet e que, construídas sobre as fundações tecnológicas da Web 2.0, permitem a criação e a troca de conteúdo gerado pelos usuários. A metodologia de investigação adotada foi do tipo exploratória e descritiva, pois o tema ainda é considerado novo no meio acadêmico. Para melhor caracterização das aplicações de mídia social, foi criado um questionário do tipo estruturado e disponibilizado pela via online. Um total de cinco bancos entre públicos, privados, com atuação regional e nacional compuseram a amostra observada. A avaliação dos dados do questionário foi efetuada com o uso da técnica de análise de conteúdo, para a análise das respostas das perguntas abertas, e mensuração da intensidade das respostas obtidas pela aplicação da escala tipo Likert. O aprimoramento do relacionamento com os clientes foi a principal motivação apontada pelos bancos como justificativa do uso das mídias sociais. Verificou-se que o Facebook, o Youtube e o Twitter são as ferramentas que as instituições pesquisadas mais recorrem para construir uma identidade junto ao seu público. Apesar dos riscos associados à imagem institucional, observou-se que são empregadas estratégias para a mitigação dos comentários negativos.
A sociedade excitada e a busca de sensações: Uma análise fílmica de Black Mirror
Authors: Cardoso Moisés , Prado Junior Tarcis , Iacomini Junior Franco
Published: June 2019

A Internet está presente no dia-a-dia de todos, cada vez mais nos sentimos impulsionados a compartilhar diferentes informações nos meios digitais, que encurtam barreiras físicas e culturais. Dentro desde contexto tecnológico, este artigo se propõe analisar a série “Black Mirror”, criada por Charlie Brooker e popularizada pelo Netflix. A seleção das cenas para o trabalho estabelece como critério o episódio 03x01, chamado de “Nosedive”. Como metodologia foi utilizada a análise fílmica tensionada com os conceitos da “sociedade excitada” (TÜRCKE, 2010); a “modernidade liquida” de Bauman (2003) e os “meios de comunicação” de McLuhan (2007), inseridos na narrativa investigada por meio de reiterações imagéticas. Os resultados apontaram que as imagens provocam choques, sensações a um modo de sonhar material que sacraliza o imediatismo. Conduz a uma excitação social contínua causando um frenesi viciante pela aceitação social presente nas plataformas digitais.

Do pedal ao violão: uma análise folkcomunicacional das músicas do artista Plá nas Bicicletadas em Curitiba
Authors: Belin Luciane Leopoldo , Orlandini Maiara Garcia , Dalla Costa Rosa Maria
Published: June 2019

Nos últimos anos, o aumento da frota de automóveis como meio de transporte prioritário nas grandes cidades tem incentivado o surgimento de grupos populares que se manifestam pelo uso da bicicleta para locomoção no dia a dia. Inspirada por movimentos internacionais, a Bicicletada é um destes grupos marginalizados que, através de eventos e ações de manifestação cultural, comunica sua demanda social. Entre estas expressões culturais estão as músicas compostas pelo artista popular Plá, membro ativo das Bicicletadas e considerado um líder de opinião, já que atua de maneira a comunicar para a sociedade a demanda de um pequeno grupo. Neste artigo, analisam-se canções compostas por este artista sob a perspectiva da folkcomunicação, cunhada por Luis Beltrão, para observar sob quais aspectos se configuram como um objeto de folkcomunicação. Constatou-se, a partir da análise de conteúdo de 23 canções, que estas atuam como expressão de manifestações culturais, pois transformam a luta em objeto musical e comunicacional, expandindo o universo da discussão e apresentando-a à população da cidade por meio de suas músicas.
