PANORAMA DO USO DE AGROTÓXICOS NA BAHIA: DESAFIOS PARA A VIGILÂNCIA À SAÚDE
Authors: De Abreu Ruy Muricy , Tavares Felipe Guimarães
Published: September 2017

O atual modelo agrícola do Brasil foi gestado a partir dos anos 60 do século passado e ocorreu por meio de incentivos fiscais, isenções tributárias e financiamento público subsidiado, visando atrair capitais estrangeiros para instalação de fábricas para a produção de agrotóxicos, fertilizantes sintéticos, máquinas e implementos agrícolas, priorizando-se as monoculturas de exportação. Este artigo tem como objetivo descrever a situação de uso de agrotóxicos no estado da Bahia, correlacionando-a ao cenário nacional, identificando semelhanças e peculiaridades em relação aos riscos à saúde humana e ao meio ambiente. O método adotado foi a análise descritiva fundamentada por revisão de literatura e bases de dados do Sistema de Informação de Agravos de Notificação e do Sistema Nacional de Informações Tóxico-Farmacológica. Os resultados do estudo apontaram o crescimento das intoxicações e doenças nos trabalhadores agrícolas e seus familiares, presença de resíduos de agrotóxicos em alimentos, degradação da qualidade das águas, do solo, do ar e contaminação da fauna e flora, percebidos numa dimensão que não retrata a magnitude do problema. Concluiu-se que o consumo de agrotóxico na Bahia aumentou 4,2 vezes, no período de 2005 a 2012, não obstante ter havido uma pequena redução da área plantada.

The impact of ownership structure on firm performance: The role of chairman and CEO in Portugal
Authors: Ntoung Lious Agbor Tabot , Vila Biglieri Jorge Eduardo , Santos de Oliveira Helena Maria , Ferreira de Sousa Benjamim Manuel , Outman Ben C. , Masárová Eva
Published: September 2017

This analysis investigates how family ownership structure affects the corporate performance of Portuguese listed firms using a panel data set covering the period from 2006 to 2014. Three characteristics of family firms (such as active management, active founder or heir and second blockholder) were examined with respect to the corporate performance. The main finding is that family firms over perform non-family in term productivity and profitability. This indicates that companies that have total family control are more productive and profitable than those market favour firms that the family does not have total ownership. Specifically, family firms with active founders perform better whereas those with active heirs significantly outperform compared to family firms with passive owners or heirs. Family firms with a family member in the company as either CEO or Chairman create more value and are more profitable than non-family firms. Family firms with descendant as CEO perform better meanwhile family firms with the founder as CEO significantly outperform family firms with Outside CEO for corporate performance. Lastly, the presence of a second blockholder who owns between 5-10% of the voting right enhances the corporate performance of the family firms as it counterbalances the controlling shareholder from unnecessary behaviours.

Authors: Pattnaik Barsa , Rath Manoj Kumar , Jena Rakesh Kumar
Published: September 2017

This paper presents a study of reinforced concrete pipe with the application of continuous glass fiber reinforced polymer sheet (GFRP). The pipe material is considered to be composed of reinforced concrete and the pipe is strengthen by using glass fiber reinforced polymer sheet. The reinforced concrete pipe is analyzed with different layers of externally applied GFRP sheet. Analysis is carried out in commercially available ANSYS software. A finite element model is developed for the pipe wherein the material properties as mentioned are used. The solid 186 layered structural solid element has been used for discretization of the model. Two sets of GFRP sheets (4 layer and 8 Layer) were considered for the analysis. Results obtained were compared with the controlled pipe made up of reinforced concrete. Results are presented for simply supported boundary conditions for the pipe. The deformation and stress distribution across the pipe has also been analyzed

A Macroeconomic Model with Occasional Financial Crises
Authors:   Federal Reserve Bank of San Francisco, Paul Pascal
Published: September 2017

Financial crises occur out of prolonged and credit-fueled boom periods and, at times, they are initiated by relatively small shocks that can have large effects. Consistent with these empirical observations, this paper extends a standard macroeconomic model to include financial intermediation, long-term loans, and occasional financial crises. Within this framework, intermediaries raise their lending and leverage in good times, thereby building up financial fragility. Crises typically occur at the end of a prolonged boom, initiated by a moderate adverse shock that triggers a liquidation of existing investment, a contraction in lending, and ultimately a deep and persistent recession.

En torno a los orígenes del fútbol como deporte escolar en España (1883-1936). De moda recreativa a dispositivo disciplinario
Authors: Torrebadella-Flix Xavier , Vicente-Pedraz Miguel
Published: September 2017

Este artículo aborda el proceso de configuración del fútbol como deporte de masas en el entorno social, político e ideológico de finales del siglo XIX y principios del XX. Con una perspectiva genealógica describe y analiza el papel que ejerció el fútbol infantil en el desarrollo y legitimación de la práctica balompédica más allá de los muros escolares. Una lectura crítica de las fuentes documentales presentadas permite constatar que, en gran medida, la entronización del fútbol y su pronta hegemonía en el contexto del deporte español tuvo como gran valedor ideológico el discurso regeneracionista finisecular y como mejor apoyo político-administrativo al propio Estado. Este, a través del asociacionismo deportivo, los clubes juveniles parroquiales o laicos, la educación física escolar, y también a través de políticas de ordenación urbana, supo canalizar la capacidad de convocatoria del fútbol para hacer de él un eficaz aparato de disciplinamiento y control.

Perkembangan Ragam Hias Pada Batu Nisan Tipe Malik As-Shaleh Abad 13 - 17.
Authors: Inagurasi Libra Hari
Published: September 2017

Decorative variety is a decorative element, its main function as a decoration to beautify the appearance of an object so that it becomes a work of art. The function of the decoration is shown through the integrated forms, textures, materials, and art elements. An object decorated with decorative or decorative elements is a tombstone made of stone. Decorative on the gravestone is formed by sculpting then produce certain forms adorn the headstone so it looks not plain. The development of tombstones of this type and their decorations include the dimensions of time and space. The Malik As-Shaleh type headstone originally evolved from the gravestone on the tomb of Sultan Malik As-shaleh in the 13th century. The tombs spread eastwards to Sumatra, Banten, Lombok, and Gowa in South Sulawesi in the 17th century. The variety of decoration on the gravestone Malik As-Shaleh type in its development is distinguished two groups namely the first group of ornamental fashions whose existence always persists from the beginning to the end of its development and the two groups of decoration whose existence is lost or replaced with other types of decorations. The standard Malik As-Shalh standard headstone is in the tomb of Sultan Malik As-Shaleh. All kinds of decorative elements are on the tombstone so it looks beautiful or highway. The similar type of grave on another tomb has a simple ornamental variety. AbstrakRagam hias merupakan elemen dekoratif, fungsi utamanya sebagai hiasan untuk memperindah penampilan suatu obyek sehingga menjadi sebuah karya seni. Fungsi ragam hias tersebut ditunjukkan melalui bentuk, tekstur, bahan, serta unsur seni yang terpadu. Suatu obyek yang diberi elemen ragam hias atau dekoratif ialah nisan yang dibuat dari bahan batu. Ragam hias pada nisan dibentuk dengan cara dipahat selanjutnya menghasilkan bentuk-bentuk tertentu menghiasi nisan sehingga terlihat tidak polos. Perkembangan batu nisan tipe tersebut beserta ragam hiasnya mencakup dimensi waktu dan ruang. Nisan tipe Malik As-Shaleh pada awalnya berkembang dari nisan pada makam Sultan Malik As-shaleh pada abad ke-13. Selanjunya nisan  menyebar ke arah timur ke Sumatra, Banten, Lombok, dan Gowa di Sulawesi Selatan pada abad ke-17. Ragam hias pada nisan tipe Malik As-Shaleh dalam perkembangannya dibedakan dua kelompok yakni pertama kelompok ragam hias yang keberadaannya selalu tetap ada dari awal hingga akhir perkembangannya dan kedua kelompok ragam hias yang keberadaannya hilang atau diganti dengan ragam hias jenis lainnya. Nisan tipe Malik As-Shaleh yang standar terdapat  pada makam Sultan Malik As-Shaleh. Semu jenis elemen dekoratif terdapat pada nisan tersebut sehingga terlihat indah atau raya.

Relationships Between Instructional Quality and Classroom Management for Beginning Urban Teachers
Authors: Kwok Andrew
Published: September 2017

This mixed-methods study explores the differences in 1st-year urban teachers’ classroom management beliefs and actions. The teachers in this study were in their first year of teaching in an urban context concurrent with their participation in a teacher education program offered at a large public university. Using program-wide surveys of 89 elementary and secondary teachers and qualitative data from five case participants, this study explores teachers’ behavioral, academic, and relational beliefs and how these beliefs shape the actions used in managing their classrooms. Specifically, the participants focused on both student behavior and academics when managing classrooms and did not singularly consider enforcing behavioral systems for obtaining teacher authority. Even with this focus, some of the participants were more relational in their classroom management approach and actively searched for ways to build relationships with students. More relational classroom managers were associated with higher ratings of instructional quality. These findings speak to the need for future large-scale studies on the use of relational classroom management approaches and how those approaches relate to instructional quality.
Failed Citizenship and Transformative Civic Education
Authors: Banks James A.
Published: September 2017

Global migration, the quest by diverse groups for equality, and the rise of populist nationalism have complicated the development of citizenship and citizenship education in nations around the world. Many racial, ethnic, cultural, linguistic, and religious groups are denied structural inclusion into their nation-state. Consequently, they do not fully internalize the values and symbols of the nation-state, develop a strong identity with it, or acquire political efficacy. They focus primarily on particularistic group needs and goals rather than the overarching goals of the nation-state. I conceptualize this process as failed citizenship and present a typology that details failed, recognized, participatory, and transformative citizenship. I describe the role of the schools in reducing failed citizenship and helping marginalized groups become efficacious and participatory citizens in multicultural nation-states.
The Sensitivity of Teacher Performance Ratings to the Design of Teacher Evaluation Systems
Authors: Steinberg Matthew P. , Kraft Matthew A.
Published: September 2017

In recent years, states and districts have responded to federal incentives and pressure to institute major reforms to their teacher evaluation systems. The passage of the Every Student Succeeds Act in 2015 now provides state policymakers with even greater autonomy to redesign existing evaluation systems. Yet, little evidence exists to inform decisions about two key system design features: teacher performance measure weights and performance ratings thresholds. Using data from the Measures of Effective Teaching study, we conduct simulation-based analyses that illustrate the critical role that performance measure weights and ratings thresholds play in determining teachers’ summative evaluation ratings and the distribution of teacher proficiency rates. These findings offer insights to policymakers and administrators as they refine and possibly remake teacher evaluation systems.
Untersuchung des Verschleißverhaltens von TiB2-beschichteten Mikrofräswerkzeugen
Authors: Bohley Martin , Heberger Lukas , Kirsch Benjamin , Aurich Jan C.
Published: September 2017

Kurzfassung

Beim Einsatz von Mikrofräswerkzeugen kommt es, bedingt durch Größeneffekte, zu erhöhter Reibung und damit erhöhtem Verschleiß. Zusätzlich resultieren aus den geringen Werkzeugdurchmessern niedrige Schnittgeschwindigkeiten, sodass es zu Aufbauschneiden kommen kann. Beides wirkt sich negativ auf die Prozessergebnisgrößen aus und reduziert die Effizienz des Prozesses. Um dies zu minimieren, wurden Mikrofräswerkzeuge (Ø 50 μm) mit einer PVD-Beschichtung versehen und das Einsatzverhalten untersucht.

Published: September 2017

Kurzfassung

Die vierte industrielle Revolution, auch als Industrie 4.0 bekannt, ist eine der größten Herausforderungen, denen sich kleine und mittelständische Unternehmen (KMU) heute und besonders in Zukunft stellen müssen. Viele von ihnen sind bereits seit Jahrzehnten Marktführer und haben erfolgreich ihre Produkte und Dienstleistungen in einer „Offline“-Welt optimiert. Die Integration von smarten Produkten und Dienstleistungen im Hinblick auf Industrie 4.0 bietet dabei neue Möglichkeiten und Ebenen, Nutzen in der Wertschöpfungskette zu schaffen. Die Identifizierung dieser schlummernden Werte und die Entwicklung von neuen Geschäftsmodellen stellen heute eine große Hürde für KMU dar. Dieser Beitrag stellt daher eine von TRIZ abgeleitete Neun-Felder-Matrix und eine morphologische Analysemethode vor, die KMU dabei unterstützen soll, informationsbasierte Industrie-4.0-Geschäftsmodelle auf der Basis bestehender Produkte und Dienstleistungen zu identifizieren und zu entwickeln. Die praktische Anwendbarkeit der Methode wird anhand eines industriellen Fallbeispiels gezeigt.

Investigating the Spatial Distribution of Manufacturing Employment
Authors: Chacon-Hurtado Davis , Pyrialakou V. Dimitra , Gkritza Konstantina
Published: September 2017

An extensive body of research examines the relationship between transportation and economic activity in a region; however, many of the studies ignore the possible spatial interdependencies between regions. As a result, these studies may over- or underestimate the role that transportation plays on the economic activity of a region. This paper contributes to the literature by exploring the relationship between the supply of transportation infrastructure and manufacturing employment concentration through a model that accounts for the spatial structure of the data at the zip code level. The modeling approach, which is demonstrated with a case study in Indiana, accounts for spillovers across areas by using a spatial autoregressive model with autoregressive disturbances. The results indicate that the high concentration of manufacturing employment in Indiana has been strongly associated with proximity to industrial parks, low commuting time, a higher percentages of firms with more than 100 employees, lower highway density, and proximity to intermodal facilities. The results of this study could benefit metropolitan or rural planning organizations and economic development groups that aim to design policies or plans to attract manufacturing activity to their regions.
Bilateral vestibulopathy: Diagnostic criteria Consensus document of the Classification Committee of the Bárány Society1
Authors: Strupp Michael , Kim Ji-Soo , Murofushi Toshihisa , Straumann Dominik , Jen Joanna C. , Rosengren Sally M. , Della Santina Charles C. , Kingma Herman
Published: September 2017

This paper describes the diagnostic criteria for bilateral vestibulopathy (BVP) by the Classification Committee of the Bárány Society. The diagnosis of BVP is based on the patient history, bedside examination and laboratory evaluation. Bilateral vestibulopathy is a chronic vestibular syndrome which is characterized by unsteadiness when walking or standing, which worsen in darkness and/or on uneven ground, or during head motion. Additionally, patients may describe head or body movement-induced blurred vision or oscillopsia. There are typically no symptoms while sitting or lying down under static conditions. The diagnosis of BVP requires bilaterally significantly impaired or absent function of the vestibulo-ocular reflex (VOR). This can be diagnosed for the high frequency range of the angular VOR by the head impulse test (HIT), the video-HIT (vHIT) and the scleral coil technique and for the low frequency range by caloric testing. The moderate range can be examined by the sinusoidal or step profile rotational chair test. For the diagnosis of BVP, the horizontal angular VOR gain on both sides should be <0.6 (angular velocity 150–300°/s) and/or the sum of the maximal peak velocities of the slow phase caloric-induced nystagmus for stimulation with warm and cold water on each side <6°/s and/or the horizontal angular VOR gain <0.1 upon sinusoidal stimulation on a rotatory chair (0.1 Hz, Vmax = 50°/sec) and/or a phase lead >68 degrees (time constant of <5 seconds). For the diagnosis of probable BVP the above mentioned symptoms and a bilaterally pathological bedside HIT are required. Complementary tests that may be used but are currently not included in the definition are: a) dynamic visual acuity (a decrease of ≥0.2 logMAR is considered pathological); b) Romberg (indicating a sensory deficit of the vestibular or somatosensory system and therefore not specific); and c) abnormal cervical and ocular vestibular-evoked myogenic potentials for otolith function. At present the scientific basis for further subdivisions into subtypes of BVP is not sufficient to put forward reliable or clinically meaningful definitions. Depending on the affected anatomical structure and frequency range, different subtypes may be better identified in the future: impaired canal function in the low- or high-frequency VOR range only and/or impaired otolith function only; the latter is evidently very rare. Bilateral vestibulopathy is a clinical syndrome and, if known, the etiology (e.g., due to ototoxicity, bilateral Menière’s disease, bilateral vestibular schwannoma) should be added to the diagnosis. Synonyms include bilateral vestibular failure, deficiency, areflexia, hypofunction and loss.
Strategy in the Public and Private Sectors: Similarities, Differences and Changes
Authors: Alford John , Greve Carsten
Published: September 2017

Strategic concepts and practices first evolved in the private sector, so they evoked much controversy when they migrated to the public sector from the late 1970s onwards. Partly this was about their (in)applicability to the distinctive features of government organizations, in particular their focus on public as well as private value, their situation in a political rather than a market environment, their almost exclusive capacity to use legal authority to achieve purposes, and the extent to which they often need to share power over personnel and resources with other public sector agencies. These and other factors complicated efforts to apply New Public Management and similar frameworks in strategy concepts in a governmental context. Partly also the traditional private-sector focus on single organizations did not resonate with the growth of network governance from the 1990s. The authors argue for an alternative model based primarily on the public value framework as a means of incorporating and going beyond traditional strategy thinking.

VetCompass Australia is veterinary medical records-based research coordinated with the global VetCompass endeavor to maximize its quality and effectiveness for Australian companion animals (cats, dogs, and horses). Bringing together all seven Australian veterinary schools, it is the first nationwide surveillance system collating clinical records on companion-animal diseases and treatments. VetCompass data service collects and aggregates real-time, clinical records for researchers to interrogate, delivering sustainable and cost-effective access to data from hundreds of veterinary practitioners nationwide. Analysis of these clinical records will reveal geographical and temporal trends in the prevalence of inherited and acquired diseases, identify frequently prescribed treatments, revolutionize clinical auditing, help the veterinary profession to rank research priorities, and assure evidence-based companion-animal curricula in veterinary schools. VetCompass Australia will progress in three phases: (1) roll-out of the VetCompass platform to harvest Australian veterinary clinical record data; (2) development and enrichment of the coding (data-presentation) platform; and (3) creation of a world-first, real-time surveillance interface with natural language processing (NLP) technology. The first of these three phases is described in the current article. Advances in the collection and sharing of records from numerous practices will enable veterinary professionals to deliver a vastly improved level of care for companion animals that will improve their quality of life.
Postharvest Behavior of Bioactive Compounds in Tomato Fruits Treated with Cu Nanoparticles and NaCl Stress
Authors: Hernández-Fuentes Alma , López-Vargas Esly , Pinedo-Espinoza José , Campos-Montiel Rafael , Valdés-Reyna Jesús , Juárez-Maldonado Antonio
Published: September 2017

Tomatoes are important for human diet due to their content of bioactive compounds. However, is little known about behavior of these compounds during fruit shelf life. The goal of this research was to evaluate the effects on bioactive compounds of tomato fruits stored during different times and conditions, obtained from tomato plants developed under conditions of saline stress and with the application of copper nanoparticles. Four treatments were evaluated: foliar spray of copper nanoparticles (250 mg L−1) with or without saline stress, only saline stress, and the absolute control. The results show that application of copper nanoparticles has a positive effect on the accumulation of bioactive compounds such as total phenols, β-carotene, and vitamin C. The saline stress during the development of tomato plants causes a decrease of the bioactive compounds as well as antioxidant capacity in tomato fruits. However, this negative effect can be reduced with the application of copper nanoparticles. The application of copper nanoparticles may be a technique to increase and maintain the content of bioactive compounds in tomato fruits and can be an effective alternative to diminish the negative effects on bioactive compounds caused by saline stress.

Undesirable vibrations occurring in undersea pipeline structures due to ocean currents may shorten the lifecycle of pipeline structures and even lead to their failure. Therefore, it is desirable to find a feasible and effective device to suppress the subsea vibration. Eddy current tuned mass damper (ECTMD), which employs the damping force generated by the relative movement of a non-magnetic conductive metal (such as copper or aluminum) through a magnetic field, is demonstrated to be an efficient way in structural vibration control. However, the feasibility and effectiveness of ECTMD in a seawater environment has not been reported on before. In this paper, an experiment is conducted to validate the feasibility of an eddy current damper in a seawater environment. A submerged pipeline is used as the controlled structure to experimentally study the effectiveness of ECTMD. The dynamic properties of the submerged pipeline are obtained from dynamic tests and the finite element method (FEM). The optimum design of TMD with a linear spring-damper element for a damped primary structure is carried out through numerical optimization procedures and is used to determine the optimal frequency tuning ratio and damping ratio of ECTMD. In addition, the performance of ECTMD to control the submerged pipeline model is respectively studied in free vibration case and forced vibration case. The results show that the damping provided by eddy current in a seawater environment is only slightly varied compared to that in an air environment. With the optimal ECTMD control, vibration response of the submerged pipeline is significantly decreased.

Based on tunable diode laser absorption spectroscopy (TDLAS), two-dimensional (2D) distribution reconstructions of gas concentration and temperature are realized using an algebraic reconstruction technique (ART). The influence of the beam distribution and grid size on combustion field reconstruction is investigated to attain optimal reconstruction results with a limited number of beams. Under limited optical-path numbers, it shows that a better spatial resolution is attainable only when the laser beam paths are vertical and parallel to the symmetry axis of the combustion field. Furthermore, experiments with 16 beam paths using one and two flat flame combustion fields are carried out in different fuel-air equivalence ratios under room temperature. The results are in agreement with the simulation results, and the time resolution is less than 1 s.

Published: September 2017

In this study, the ambient aerosol (PM10) concentrations of elemental carbon (EC), organic carbon (OC), total carbon (TC), and levoglucosan are reported for a Polish health resort following a one-year (March 2016–April 2017) sampling campaign. The seasonal variation of OC, EC, and levoglucosan (LG) concentrations showed their maximum during the heating season for this site, with monthly mean total carbonaceous material/PM10 ratios ranging between about 0.28 and 0.44 depending on the season. Average EC concentration was 1.1 ± 0.6 µg∙m−3 and changed from 0.3 µg∙m−3 up to 2.3 µg∙m−3 during the sampling campaign. The OC concentration at the site ranged from 2.4 µg∙m−3 during the non-heating season up to 22 µg∙m−3 in the heating season, with an average of 7 µg∙m−3. A strong correlation between OC and EC in the heating season suggested that they were produced from similar sources during this time. Mean LG concentration during the sampling campaign was 0.51 µg∙m−3, while in the heating season it was 0.72 µg∙m−3 and in 0.19 µg∙m−3 in the non-heating season. The obtained results indicated a strong influence of local primary source emissions on air quality, especially during the heating period.

This paper proposes a facile strategy for the zwitterionization of bioceramics that is based on the direct incorporation of l-lysine amino acid via the ε-amino group onto mesoporous MCM-41 materials. Fourier transform infrared (FTIR) studies of lysine-grafted MCM-41 (MCM-LYS) simultaneously showed bands at 3080 and 1540 cm−1 and bands at 1625 and 1415 cm−1 corresponding to -NH3+/COO− pairs, which demonstrate the incorporation of the amino acid on the material surface keeping its zwitterionic character. Both elemental and thermogravimetric analyses showed that the amount of grafted lysine was 8 wt. % based on the bioceramic total weight. Moreover, MCM-LYS exhibited a reduction of adhesion of S. aureus and E. coli bacteria in 33% and 50%, respectively at physiological pH, as compared with pristine MCM-41. Biofilm studies onto surfaces showed that lysine functionalization elicited a reduction of the area covered by S. aureus biofilm from 42% to only 5% (88%). This research shows a simple and effective approach to chemically modify bioceramics using single amino acids that provides zwitterionic functionality, which is useful to develop new biomaterials that are able to resist bacterial adhesion.
Alcohol Misuse Link to POEMS Syndrome in a Patient

Published: September 2017

Previously called Crow–Fukase syndrome, POEMS syndrome is characterized by poly-neuropathy, osteo-sclerotic myeloma, organomegaly, endocrinopathy, monoclonal plasma cell disorder, and skin changes. Extremely elevated levels of serum vascular endothelial growth factor (VEGF) are characteristic of the syndrome. Chronic hepatitis B (HBV) and C (HCV) infections can also be present in POEMS. The pathogenesis of the syndrome is not well understood. The link between chronic alcohol consumption and this malignant condition has not been reported until now. In addition, no previous study has evaluated the influence of cytokine and chemokines or viruses in the severity and evolution of POEMS. Objectives: (1) to describe a heavy-alcohol user, who was diagnosed with POEMS; (2) to demonstrate the utility of quantitative measurement of serum levels of VEGF in the diagnosis of POEMS and the monitoring of therapeutic interventions; (3) to demonstrate that overproduction of pro-inflammatory cytokines is a characteristic of POEMS. Methods: We describe a case of a POEMS patient presenting HCV and who is a heavy drinker; we compare the serum levels of cytokines and chemokines between the POEMS patient with 80 patients with HCV, 12 healthy controls, and 80 individuals with alcoholic liver disease (ALD). We quantified (ELISA pg/mL) the levels of VEGF, Interferon gamma (IFN-γ), Tumor Necrosis Factor alpha (TNF-α), Regulated-upon-Activation Normal-T-cell-Expressed and presumably-Secreted (RANTES), and Nuclear Factor kappa-B (NFκB). Results: In POEMS patients, VEGF levels were elevated versus control or other diseases, TNFα levels were higher versus control, but lower when compared with HCV or ALD patients. VEGF levels in POEMS patients decreased with therapeutic intervention. Conclusions: Chronic alcohol misuse can be a strong risk factor to rare malignancies such as POEMS syndrome. Extreme elevation of VEGF levels is diagnostic for POEMS syndrome, and should be followed to assess response to therapy. In addition, other comorbidities should be considered individually to ensure personalized therapeutic intervention.

Primary tumors of the liver represent the fifth most common type of cancer in the world and the third leading cause of cancer-related death. Case-control studies from different countries report that chronic ethanol consumption is associated with an approximately 2-fold increased odds ratio for hepatocellular carcinoma (HCC). Despite the substantial epidemiologic data in humans demonstrating that chronic alcohol consumption is a major risk factor for HCC development, the pathways causing alcohol-induced liver cancer are poorly understood. In this overview, we summarize the epidemiological evidence for the association between alcohol and liver cancer, review the genetic, oncogenic, and epigenetic factors that drive HCC development synergistically with ethanol intake and discuss the essential molecular and metabolic pathways involved in alcohol-induced liver tumorigenesis.

Butadiene polymerization, in both a highly cis- and trans-specific manner, was achieved by using a Cp*Nd(BH4)2(thf)2–Bu2Mg system as an initiator. The cis-/trans- ratio can be tuned by the amount of trialkylaluminum-depleted modified methylaluminoxane (dMMAO). The cis-regularity of the polymer was much higher than those obtained by Nd(BH4)3(thf)3. The molecular weight of cis-regular polymer was increased according to polymer yield, showing that there was no termination or chain transfer reaction during the polymerization. Synthesis of stereodiblock polybutadiene, which showed a high melting temperature (Tm) compared with stereodiblock polyisoprene, was also performed by the addition dMMAO during the polymerization.

Recently, transition metal dichalcogenides (TMDs), represented by MoS2, have been proven to be a fascinating new class of electrocatalysts in hydrogen evolution reaction (HER). The rich chemical activities, combined with several strategies to regulate its morphologies and electronic properties, make MoS2 very attractive for understanding the fundamentals of electrocatalysis. In this review, recent developments in using MoS2 as electrocatalysts for the HER with high activity are presented. The effects of edges on HER activities of MoS2 are briefly discussed. Then we demonstrate strategies to further enhance the catalytic performance of MoS2 by improving its conductivity or engineering its structure. Finally, the key challenges to the industrial application of MoS2 in electrocatalytic hydrogen evolution are also pointed out.
