Authors: Zhang Ruxin , Hou Bing , Shan Qinglin , Lin Botao , Lu Yunhu , Wang Yajun , Zhang Xiang
Published: January 2018

Coplanar perforation is a new perforation technology with unique perforation position that can improve the efficiency of hydraulic fracturing of horizontal wells in low permeability reservoirs which have low porosity, low permeability and are difficult to explore. So it is important to know how fractures initiate and propagate as well as the optimal perforation parameters.

A large-scale true tri-axial hydraulic fracturing simulation experiment is conducted to study fracture initiation characteristic and propagation pattern of coplanar perforation in horizontal wells under different in-situ stresses, compared with conventional helix perforation in horizontal wells under the same in-situ stresses. In the meantime, the three-dimensional finite element method is used to study the influences of different perforation parameter combinations set according to field data on fracturing pressure in horizontal wells, including shot length, shot diameter and shot density.

The experiment results show that the coplanar perforation has simpler fracture propagation pattern under higher stress difference and has following advantages compared to conventional helix perforation: (1) reducing the fracturing pressure, (2) controlling the fracture propagation to reduce the complexity of near-wellbore fracture and (3) reducing the near-wellbore friction resistance. The numerical simulation results show that: (1) the fracturing pressure does not decrease linearly as the shot density increases, it falls rapidly when the shot density increases from 9 to 15 holes per meter, but when the shot density increases from 15 to 21 holes per meter, it falls slowly and finally remains almost constant, (2) the fracturing pressure decreases as the shot diameter increases, and (3) the fracturing pressure stays the same as the shot length increases. Through the conclusions of experimental and numerical simulation, we could provide some valuable suggestions to the hydraulic fracturing on filed. During hydraulic fracturing process in low permeability reservoirs, coplanar perforation technology with high shot density (21 holes/m) and large shot diameter (0.03m) should be used.

The experimental and numerical simulation conducted in this paper show a real process of hydraulic fracturing with coplanar perforation. The advantages and optimal perforation parameters of coplanar perforation are proposed to give guidances for hydraulic fracturing on field.
An Enhanced Experimental Method to Assess the Shale Inhibition Durability of Inhibitive Water-Based Drilling Fluids
Authors: Al-Arfaj Mohammed K. , Amanullah Md , Mohammed Al-Osail
Published: January 2018

When drilling shale formations with water-based drilling fluids, wellbore instability problems arise from the interaction of water with clay minerals. As a result, there will be higher solids loading into the wellbore and the borehole diameter will not be constant along the depth of the well. Hence, the chance to get pipe stuck increases and the hole cleaning efficiency of drilling mud decreases significantly. To combat shale drilling problems, different types of inhibitive water-based muds were developed. The performance and effectiveness to inhibit shale formations vary between one type of shale inhibitors to the other. Oil and gas industry has standard procedures to test the inhibition performance of drilling fluids such as dispersion test and swelling test. This paper builds on that and introduces a method to test the long-term shale inhibition capability of shale inhibitors. Due to the presence of some unique geological conditions, sometimes there is a need to replace a high cost inhibitive mud by a low cost non-inhibitive mud to drill the next formation. If the original inhibition provided by the inhibitive drilling fluid does not last long enough to drill the second zone, the previously drilled inhibitive shale formation starts reacting again with the non-inhibitive drilling fluid leading to various drilling problems. Hence, there is a need for isolation of the reactive shale zone by a casing string before drilling ahead. Inhibitive muds with long-term inhibition potential such as 24 hours or more may eliminate the need of a protective casing for the previously drilled shale formation.
7- × 4 1/2-in. Monobore Completion System Capable of 15-ksi Treating Pressures in Hydraulic Fracturing Applications for Deep Gas Wells
Authors: AlGhuryafi Ahmed M. , Garrido Cruz Raul A. , Ashby Scott F. , Abuelnaga Ahmed
Published: January 2018

The increasing need for completions to be capable of withstanding higher treating pressures, combined with complex well geometries and cementing requirements, led to the development of a new 4 1/2-in. completion system that includes liner systems to facilitate isolation objectives, and upper completion systems to create a monobore conduit. This new monobore completion system is rated for 15,–KSI target surface treating pressures.

Traditionally, cementing and isolation objectives have been achieved using liners and liner hangers capable of deploying those liners and also isolating the target zone. To achieve a monobore completion design, an integral tieback receptacle (TBR) is used to tie the liner back to surface. The integral TBRs currently used are either too short to enable the necessary tubing movement stroke, or rated too low to enable the required treating pressure.

A solution was developed integrating a lower polished bore receptacle (PBR) below the liner hanger that is capable of withstanding the pressure requirements, and using a compression-set anchoring system to anchor a seal assembly inside the PBR. To account for tubing movement and help reduce mechanical loading on the tubing and upper completions components, a PBR is placed above the compression-set anchor.

This arrangement enables the liner hanger systems to be isolated from treating pressures, which helps remediate limitations associated with traditional completion systems. Considering that the liner hanger is isolated from tubing treating pressures and that the compression-set anchor does not isolate annular pressure, the TBR on the liner hanger is pressure-balanced, no longer exceeding the pressure limit. Furthermore, tubing-casing annulus (TCA) pressure that is normally applied during stimulation can now support the liner hanger and lower tieback seals.
Optimizing the Application of Underbalanced Drilling Through the Use of Air and Foam Systems in Low-Pressure Gas Reservoirs
Authors: Porter Mika , Hill Adam , Vieira Paco , Wuest Chad , Gregorio Adrian Paul , Sardo Antonio , Orta Cesar
Published: January 2018

In global underbalanced drilling (UBD) applications, the main contributing factor for downhole fires is often attributed to the use of air as the primary gaseous phase in the reservoir interval. The industry has adopted a general practice to avoid using air in UBD operations in the presence of hydrocarbons. This paper challenges this paradigm by discussing the planning and application of a successful air-foam UBD application in Australia to drill a low-pressure, highly depleted, gas-bearing reservoir. By using air as the primary fluid medium and eliminating the need for membrane-produced nitrogen, the UBD cost was reduced by 25% and reservoir deliverability exceeded the production expectations. This paper discusses the risk mitigations, modeling, and technical justification applied to the challenging project to demonstrate that even when inert gases may be the recommended choice, air can be used safely in some cases to optimize operational efficiency and cost.

Stimuli Responsive Nanoparticles for Controlled Anti-cancer Drug Release
Authors: Tang Qi , Yu Bing , Gao Lilong , Cong Hailin , Song Na , Lu Chenghao
Published: January 2018

Conventional drugs used for cancer chemotherapy have severe toxic side effects
and show individually varied therapeutic responses. The convergence of nanotechnology,
biology, material science and pharmacy offers a perspective strategy for cancer chemotherapy.
Nanoparticles loaded with anti-cancer drug have been designed to overcome the limitations
associated with conventional drugs, several nanomedicines have been approved by
FDA and shown good performances in clinical practice. However, the therapeutic efficacies
cannot be enhanced. Taking this into account, stimuli responsive nanoparticles present the
ability to enhance therapeutic efficacy and reduce side effects. In this review, we systematically
summarized the recent progresses of controlled anti-cancer drug release systems based
on nanoparticles with different stimuli response including pH, temperature, light, redox and
others. If the achievements of the past can be extrapolated into the future, it is highly likely
that responsive nanoparticles with a wide array of desirable properties can be eventually developed
for safe and efficient cancer therapy.

Published: January 2018

Enthusiasm for the use of dietary bioactive compounds as chemopreventive agents and adjuvants
for current therapies has increased laboratory research conducted on several types of cancers
including Head and Neck Squamous Cell Carcinoma (HNSCC). The green chemoprevention movement
is a modern approach to highlight healthy lifestyle changes that aim to decrease the incidence of
HNSCC. A healthy diet can be an effective way to prevent the development of oral cancers. Discovery
of the naturally occurring plant based compounds called phytochemicals has facilitated the development
of new treatment strategies for patients that are at risk for, or have developed HNSCC. Many
of these compounds have been shown to elicit very potent anti-carcinogenic properties. While there
are many compounds that have been studied, the compounds from two specific categories of phytochemicals,
phenolics (resveratrol, EGCG, curcumin, quercetin, and honokiol) and glucosinolates (sulforaphane,
PEITC and BITC), are emerging as potent and effective inhibitors of oral carcinogenesis.
These compounds have been shown to inhibit HNSCC growth through a variety of mechanisms. Research
has demonstrated that these compounds can regulate cancer cell proliferation through the regulation
of multiple cell signaling pathways. They can impede cell cycle progression, induce differentiation
and apoptosis, prevent angiogenesis, and inhibit cancer cell invasive and metastatic properties.
They can protect normal cells during treatment and reduce the damage caused by chemotherapy and
radiotherapy. This review aims to provide an overview of some of the most effective phytochemicals
that have the potential to successfully prevent and treat head and neck squamous cell carcinoma.

Liquid Chromatography Analysis of Clozapine in Rat Brain Tissue, Using its Molecularly Imprinted Polymer after Administration of Toxic Dose of Drug and Lipid Emulsion Therapy
Authors: Yousefsani Bahareh Sadat , Mohajeri Seyed Ahmad , Moshiri Mohammad , Hosseinzadeh Hossein
Published: January 2018

Background:

Molecularly imprinted polymers (MIPs) are synthetic polymers that have a selective site for a given analyte, or a group of structurally related compounds, that make them ideal polymers to be used in separation processes.

Objective:

An optimized molecularly imprinted polymer was selected and applied for selective extraction and analysis of clozapine in rat brain tissue.

Methods:

A molecularly imprinted solid-phase extraction (MISPE) method was developed for preconcentration and cleanup of clozapine in rat brain samples before HPLC-UV analysis. The extraction and analytical process was calibrated in the range of 0.025-100 ppm. Clozapine recovery in this MISPE process was calculated between 99.40 and 102.96%. The limit of detection (LOD) and the limit of quantification (LOQ) of the assay were 0.003 and 0.025 ppm, respectively. Intra-day precision values for clozapine concentrations of 0.125 and 0.025 ppm were 5.30 and 3.55%, whereas inter-day precision values of these concentrations were 9.23 and 6.15%, respectively. In this study, the effect of lipid emulsion infusion in reducing the brain concentration of drug was also evaluated.

Results:

The data indicated that calibrated method was successfully applied for the analysis of clozapine in the real rat brain samples after administration of a toxic dose to animal. Finally, the efficacy of lipid emulsion therapy in reducing the brain tissue concentration of clozapine after toxic administration of drug was determined.

Conclusion:

The proposed MISPE method could be applied in the extraction and preconcentration before HPLC-UV analysis of clozapine in rat brain tissue.
Antifogging and Antireflective Coatings by Spin-LbL Assembly of SiO2 and ZrO2 Nanoparticles
Authors: Yang Fusheng , Wang Peng , Yang Xiaoli , Cai Zaisheng
Published: January 2018

Background:

Fogging is a common phenomenon and often causes trouble to people in
daily life. Antifogging (AF) and Antireflective (AR) coatings can be effectively used to provide resistance
to fogging and maintain the optical clarity in day-to-day life. For this reason, they are useful
for maintaining optical clarity in optical instrument and display devices.

Methods:

Antifogging and antireflective coatings were fabricated using a Spin-LbL assembly process,
and this process is driven by electrostatic interactions between the positively charged ZrO2 NPs
and negatively charged SiO2 NPs.

Results:

The textured surfaces and void fraction can signicantly enhance the wettability of surfaces
with water. And this may result in enhanced AF properties. In the Water contact angles (WCA) test, the
ZrO2/SiO2 and SiO2/ZrO2 coatings were all superhydrophilic (almost 0°, less than 0.04 s). In the boiling test
and low temperature AF test, the ZrO2/SiO2 and SiO2/ZrO2 samples showed excellent AF properties.

Conclusion:

Antifogging and antireflective coatings were fabricated via Spin-LbL assembly of the
positively charged ZrO2 NPs and negatively charged SiO2 NPs followed by calcination. The resultant
coatings showed excellent AF properties due to the superhydrophilicity of the coating, exhibited excellent
AR properties due to the low refractive index coating and an appropriate coating thickness,
and showed excellent superhydrophilic properties due to a nano-roughness structure.

Using Cocreation in the Process of Designing a Smartphone App for Adolescents and Young Adults With Cancer: Prototype Development Study (Preprint)
Authors: Elsbernd Abbey , Hjerming Maiken , Visler Camilla , Hjalgrim Lisa Lyngsie , Niemann Carsten Utoft , Boisen Kirsten Arntz , Jakobsen Jens , Pappot Helle
Published: January 2018

BACKGROUND

Adolescent and young adult (AYA) oncology and hematology is a developing field of medicine, focusing on a population that faces many challenges throughout medical treatment and beyond. Mobile health (mHealth) interventions provide exciting new opportunities for improvement of health-related quality of life (HRQoL) in AYAs with cancer. Many smartphone apps are currently available for AYAs with cancer; however, for AYAs with cancer, very few apps have been designed with direct input from AYAs themselves or have demonstrated their effectiveness and benefit.

OBJECTIVE

The objective of this project was to develop the prototype of a smartphone app for AYAs with cancer through the process of cocreation, with the active input of AYAs who have received treatment for cancer directly impacting content and design.

METHODS

Patients were recruited from a population of Danish AYAs who had received treatment for cancer between the ages of 15 and 29 years. The cocreation process was completed over the course of 3 workshops and intermittent ad hoc meetings, where the recruited AYAs worked in coordination with 1 nurse, 1 doctor, and 2 representatives from a digital agency and app developer. During each workshop, participants prioritized their goals for the app. After new app content was developed, feedback was requested from the participants, and changes were made accordingly. This iterative process continued until consensus on final product features and design were achieved. Health care professionals provided minimal input and primarily performed observational roles in the workshops, with direct interaction limited to introducing the project and explaining measurement features of the app in development.

RESULTS

Three key features to be included in the prototype app were identified from the cocreation workshops: (1) a community forum; (2) an information library; and (3) a symptom and side-effect tracking tool. Bright, warm colors were selected for the app by the participating AYAs. The final prototype will be launched for pilot testing and implementation testing in February of 2018.

CONCLUSIONS

The process of cocreation is a user-involved process that can create an end product that is useful and customized for the target population. This process, as such, is a beneficial process to utilize when addressing the specific needs of AYAs with cancer. The results of the here described app prototype will be evaluated in more detail in the near future. However, this description of the cocreation process in app development can be utilized for the creation of other mHealth interventions.
Property and the Drafting of the Australian Constitution
Authors: Evans Simon
Published: January 2018

In this article, I present the results of a study into the extent to which property figured as a constitutional and political concept in the drafting of the Constitution at the Australasian Federal Conventions of the 1890s. Property is a fundamental concept of western legal orders and a powerful political and rhetorical tool. Accordingly, it is important to understand both how it affected the drafting of the Constitution and how it is reflected in it. In Section I, I outline the process by which the Constitution was drafted by the Australasian Federal Conventions in the 1890s. In Section II, I identify the constitutional provisions in which ‘property’ and some related terms appear and assess the extent to which the Conventions shed light on the meaning of those provisions. In Section III, I discuss the striking ways in which property, as a political concept, influenced debate at the Conventions on constitutional provisions that do not themselves deal with property. In the final section, Section IV, I attempt an overall assessment of the significance of the concept of property at the Conventions.
Rewriting the Social Contract? The SSAT, the AAT and the Contracting Out of Employment Services
Authors: Bacon Rachel
Published: January 2018

In 1998 Australia's public employment service was replaced with a national network of public, private and community agencies—the Job Network—which compete for contracts to deliver services to unemployed people. This development represents the encroachment of competition policy and market ideology into one of the most fundamental areas of government responsibility—the welfare of citizens. The broader ramifications of the contracting out of employment services in terms of quality, efficiency, social costs and accountability are only beginning to be explored. This article examines the impact these changes have had upon one important feature of the social security system—the accessibility and effectiveness of external merits review.
Patenting Genes and Gene Sequences and Competition: Patenting at the Expense of Competition
Authors: Lawson Charles
Published: January 2018

The competition principles set out in the Trade Practices Act 1974 (Cth) are based on an economic model of perfectly competitive markets responding to the market and producing only the goods and services required in the market. However, effective competition together with good market information may create a disincentive to markets innovating (market failure) because new developments may be rapidly copied without the recovery of the innovation's development costs (a free ride). According to this model, a patent under the Patents Act 1990 (Cth) compensates for the disincentive to innovate and justifies a limited period of exclusive rights during which the innovator may exclude others in order to recover the development costs (confounding the free riders) and contribute to beneficial innovation by investing in new developments (with the added benefit of disclosure of the innovation). Patents are therefore generally assumed to produce overall economic benefit while at the same time having minimal social costs. The social costs are higher prices, restricted outputs, subsidised foreign inventors and the administrative costs of the patenting scheme.
The Principle behind Common Law Judicial Review of Administrative Action—The Search Continues
Authors: Selway Bradley
Published: January 2018

The common law has had considerable difficulty in identifying a principle or principles by which to explain the role of the courts in reviewing administrative action. In this article it is argued that that principle is necessarily a constitutional principle and that the starting point for its analysis in Australian law is the Commonwealth Constitution. It is then argued that the Commonwealth Constitution, and in particular the separation of judicial power within it, necessarily limits the extent of permissible judicial review. In particular, the separation of judicial power justifies and requires the distinction between jurisdictional and non-jurisdictional errors and the distinction between invalidity and merit review in Australian administrative law. This constitutional basis for judicial review, combined with the discipline of a written Constitution, also explains why recent developments in English and New Zealand common law in relation to judicial review are not appropriate or applicable to Australia.
The Justiciability of Administrative Decisions: A Redundant Concept?
Authors: Finn Chris
Published: January 2018

The non-justiciability of certain executive decisions is based upon a number of notions including that of ‘polycentricity’, the unsuitability of certain types of power for review, deference to executive judgment, and the question of the judicially enforceable limits to power. In this article, it is argued that the concept is redundant. It is sufficient to consider whether a ground of review, invoked with an appropriate regard for the legalities merits distinction, is available. There is no further question of ‘justiciability’.

It is questionable whether it has ever really made sense to talk of ‘justiciability’ as a discrete notion, rather than justiciability upon this or that ground. Historically, it is trite to observe that questions of the existence and limits of the prerogative powers have been justiciable since at least the upheavals of the 17th century, even while courts would steadfastly refuse to examine the manner in which those powers were exercised. Thus, even prior to the decision in Council of Civil Service Unions v Minister for the Civil Service (‘CCSU’), non-justiciability in relation to prerogative powers meant simply the non availability of grounds of review other than the simplest form of ultra vires. CCSU itself established the potential availability of review of such powers for denial of procedural fairness, leaving open the question of whether the various abuse of power grounds might also be available. In short, the issue appears to be whether a decision is justiciable upon this or that ground of review, rather than the blanket availability or non availability of review. Once this point is grasped the inchoate concept of ‘justiciability’ becomes problematic at best. One need simply ask whether one or more grounds of review can be made out.
Class Actions against Multiple Respondents
Authors: Morabito Vince
Published: January 2018

On one reading of the approach by some Judges of the Federal Court to complex cases involving more than one respondent, particularly where the conduct in question involves a complicated or lengthy series of transactions, those cases should simply not be brought as class actions. If that reading is correct, then to put it bluntly, defendants are more likely to escape liability if by their conduct they cause harm or loss to more people over a greater period of time, and if they do so in concert with others.

Class actions are unlikely to flourish in Australia without a change in attitudes, both in the profession and the judiciary … Many Australian judges may still view class actions as predatory litigation instituted for the advantage of entrepreneurial lawyers.

In March 2002 the class action regime introduced by the Commonwealth Parliament, through the addition of a new Part IVA to the Federal Court of Australia Act 1976 (Cth), celebrated its tenth ‘birthday'. During this time, a number of important issues, concerning the interpretation and application of Part IVA, have emerged.
Warning Time Analysis of Nasiri River Flash Flood due to Several Possible Natural Dam Break Events
Authors: Styawan Andry Putra , Rahardjo Adam Pamudji , Sujono Joko
Published: January 2018

Flash flood disasters caused by natural dam break have already occurred several times in Indonesia which contributes so much life loss and material damage (Jember, 2006; Wasior, 2010; Nasiri, 2012; Way Ela, 2013; Magelang, 2017). This research was aimed to study threat level on flash food disasters on the possibility of the locations where the natural dam was formed by the landslide on the river cliffs at the watershed. The flash flood in Nasiri River on August 1st, 2012 would be used for the model in this research. Therefore, hydrology and hydraulic simulations would be conducted on the process of natural dam break at specified altitudes which were predicted to occur in five locations along the Nasiri River. Several big rain event data sets that could occur on specified years from the previous studies would be used to obtain rain event with the hydrological model. Natural dam break was modeled with HEC-HMS 4.1. The hydraulic simulation used the dynamic flow model in the HEC-RAS 5.3 software. The natural dam collapse would be approached by considering the event that has existed around the study location, and also the local geological condition. The result showed that for all the natural dam break scenarios, it could be concluded that the storage filling time was in the time range of 2 hours 26 minutes up to 5 minutes. The flood travel time was ranged from 27 minutes to 2 minutes. The available warning time was quite short, which was less than 3 hours; therefore the need of early warning system’s facilities and infrastructure are absolutely necessary as one of mitigation effort for flash flood disaster in Nasiri Village.
Mix Design of Self Compacting Concrete Based on Ultra High Compressive Strength Flow Mortar Mix
Authors: Wulan Soca Anggoro , Satyarno Iman , Saputra Ashar
Published: January 2018

Mix design of Self Compacting Concrete or SCC is not straight forward because many parameters control its rheological properties. The case becomes more complicated if high compressive strength is also to be achieved. Therefore simpler approach is used, that is by firstly determining the flow mortar mix which is easier to be designed even with the requirement of ultra-high compressive strength. The mix design of SCC is then determined by simply adding the coarse aggregate with a certain amount of that mortar mix. In this research the ultra-high compressive strength flow mortar was made of Type I cement, 15% of cement weight silica fume, weight ratio of cement and curve No IV sand was 1: 0.35. The water-cementious ratio was 0.22 and the amount of plasticizer was 1.3%, 1.4%, 1.5% and 1.6% of the cement weight. For the SCC, the used coefficient was taken to be 1.4, 1.6, and 1.8 of the volume of that aggregate void for mortars, the aggregate value was at the volume of the remaining count of mortar and its size was 4.8 mm - 9.6 mm. Test results show that the mortar flow ability was 170 mm, 180 mm, 220 mm and 250 mm, where the achieved compressive strength was 83.1 MPa, 96.8 MPa, 111.4 MPa, and 135.5 MPa respectively. Mortar mix with 1.6% super plasticizer was then used for making the SCC and the results show that the concrete flow were 460 mm, 580 mm and 660 mm and the compressive strength were 88.2 MPa, 100.0 MPa, and 97.9 MPa.  It can be concluded that using this simpler approach the SCC can have 580 mm flow and 100 MPa compressive strength
Contribution of Tea Root Reinforcement to Soil Shear Strength on Slope Stability

Published: January 2018

Roots played important role in the process of stabilizing the soil mass. The geo-mechanical and soil-hydrological aspects on the slope are determined by, one of it, the root reinforcement. The role of root branching series with diameter differentiation is greatly determining its tensile stress. The tensile stress from the interaction between the root and the soil, could it contribute to increasing the shear strength of the slope stability. The purpose of this research was to identify the tensile stress on root branching series that interacted with the soil and created additional cohesion as a shear strength contribution to the slope stability. Testing on the root pulling force was conducted on slope prototype with angle 30o to 40o and has been planted with tea vegetation. A tripod that was completed with strain gauge as the recording instrument was used. Testing was conducted on two and three root branching, also on each unit by observing the diameter. This testing method was done in saturated soil condition. The tensile stress result showed that increasing diameter of the tea root, an increase was noticed, and also result in the equation of TFr = 0.089e0.516d. Root diameter increase on two and three root branching to one unit of tea vegetation showed that the stress increase was significant. When observed, in the root diameter differentiation of 4 mm to 6 mm, the stress on two and three root branching and one unit of tea vegetation were respectively 5.94%, 12.30%, and 35.42%. The contribution of additional cohesion caused by root-soil interaction to soil shear strength apparently could increase slope stability.
Comunicação organizacional em ambientes peculiares: reflexões sobre diálogos em paisagens mediadas e mediadoras
Authors: Maio Ana Maria Dantas de
Published: January 2018

O domínio sobre elementos contextuais onde ocorrem interações face a face pode facilitar o planejamento e a execução de programas e ações de comunicação organizacional. Esse diferencial tende a ser mais pronunciado em ambientes considerados peculiares, como os biomas Pantanal e Amazônia, onde o apelo tecnológico é menos evidente. Empresas que atuam nesses locais e vinculam suas missões ao território podem explorar de forma profissional e estratégica a comunicação face a face, ainda pouco teorizada pelo campo da comunicação no Brasil. Este artigo investe na identificação de mediações impostas por esse tipo de ambiente e analisa a forma como esses cenários são construídos e mediados pela mídia.

The Myth of the Mad Artist: Works and Writings by Kusama Yayoi
Authors: Borggreen Gunhild
Published: January 2018

Kusama Yayoi has been active as an artist for more than 50 years, and is highly acclaimed both in her native Japan and in the United States, where she spent more than a decade of her career. A large corpus of critical reviews, catalogue texts, interviews and autobiographical writings by and about Kusama has been published over the years, and this paper investigates a specific topic in these texts concerning the discourse of madness. A persistent myth of Kusama as a'mad' artist emerged in the early and mid-1980s, but has influenced the interpretations of her whole oeuvre. Based on three texts written by Kusama, this paper shows that the artist herself did not describe her artistic processes in psychopatholocial terms at the early stages of her art production. I shall argue for more accurate interpretations of Kusama's art, based on the artist's own accounts as well as trends on the contemporary internatinoal art scene.
Between Margin and Centre: Researching "Non-standard" Japanese
Authors: Lunsing Wim
Published: January 2018

Marginality depends on the relationship with something that is constructed as central or mainstream. In cross-cultural fieldwork, the position of the reseracher in relation to his informants may be marginal. Informants may be perceived as marginal in their society. Within academia, particular topics of research may be marginalized and funding organizations may not fund such topics. In the case of my research topics of sexuality, gender and sexual activity in Japan, Japanese government funding organizations appear to be relatively receptive, providing the themes are parsed in a valid academic manner. The bigger problem was establishing academic contacts, as there are few Japanese researchers working on sexuality. As a researcher, my position was not particularly different from other people in the networks and groups concerned. The question of marginality of the informants in relation Japanese society depends greatly on one's vantage point. Generally, informants did not think in terms like marginality and in many ways they were full members of their society. Sexuality, however, is trivialized as a topic, as a result of which coming out as gay or lesbian or discussing one's activities as a a sex worker may lead to some extent of marginalization. However, this is the case with all sexuality that transgresses clearly defined boundaries. Within the academic establishment may lie the biggest problem in relation to marginality. Sexuality is often not regarded as a proper topic for investigation, which may lead to an overtheorization of issues on which few data are available. Many academics have had little sex education and their home cultures often place strong moral judgements on matters pertaining to sex, thus preventing a proper academic discussion.
The 16th Party Congress in China: A Note on Personnel Changes
Authors: Brødsgaard Kjeld Erik
Published: January 2018

At the recent 16th Party Congress a comprehensive change of the Chinese

leadership was carried through. Even though there was much

speculation as to whether Jiang Zemin and his generation would retire

as scheduled, the change of the old guard took place without much

drama when the congress finally convened in Beijing.

How do we evaluate this development? Does it mean that Chinese

politics have matured in the sense that major decisions now conform to

fixed rules and regulations rather than factional politics? Has the Chinese

political process become more transparent? Have consensual decision-

making processeses finally taken over, relegating patrimonial

policies to a phenomenon of the past? Since the mid-1990s, clear and

detailed regulations for the selection and appointment of leading cadres

have been promulgated. Is the 16th Party Congress the final step in

this process of procedural normativization? Before attempting to answer

these questions, this paper will first deal with the personnel

changes that took place at the 16th Party Congress and the Central Committee

(CC) meeting shortly after the conclusion of the conference.
Local Network Relationships and the Internationalization of Small Knowledge-Intensive Firms
Authors: Prashantham Shameen
Published: January 2018

This paper discusses the role of network relationships in the internationalization of small knowledge-intensive firms (SKIFs) by highlighting their local, spatially concentrated network relationships, which can serve as a significant local resource. Little is known in this regard with respect to a developing economy context. Primarily on the basis of a study of four case-firms in the Bangalore software industry and available secondary data, two issues are dealt with: (a) how local network relationships – such as those within clusters or industrial districts – are developed and (b) the impact that these relationships have on the internationalization of SKIFs, specifically in respect to enhancing international competitiveness. Three effects of local network relationships on the internationalization of SKIFs, viz., reputation-related, quality-related and networking benefits, are noted. However, it also emerged from follow-up interviews with local academic experts that these benefits may be passively rather than actively accrued, suggesting that some valuable local resources may be overlooked or wasted.
