Published: July 2017

BackgroundLithium is challenging to dose during pregnancy.AimsTo provide guidance for dosing lithium during pregnancy.MethodRetrospective observational cohort study. Data on lithium blood level measurements (n= 1101), the daily lithium dose, dosing alterations/frequency and creatinine blood levels were obtained from 113 pregnancies of women receiving lithium treatment during pregnancy and the postpartum period.ResultsLithium blood levels decreased in the first trimester (−24%, 95% CI −15 to −35), reached a nadir in the second trimester (−36%, 95% CI −27 to −47), increased in the third trimester (−21%, 95% CI −13 to −30) and were still slightly increased postpartum (+9%, 95% CI +2 to +15). Delivery itself was not associated with an acute change in lithium and creatinine blood levels.ConclusionsWe recommend close monitoring of lithium blood levels until 34 weeks of pregnancy, then weekly until delivery and twice weekly for the first 2 weeks postpartum. We suggest creatinine blood levels are measured to monitor renal clearance.
Prevention of bipolar episodes with lithium in the perinatal period
Authors: Wieck Angelika 
Published: July 2017

SummaryBecause lithium is now recommended as the initial long-term treatment for bipolar disorder in general and has a lower teratogenic potential than originally reported, it may become more frequently prescribed in childbearing women. The article by Wesseloo et al in this issue provides helpful data and guidance for managing lithium dosing in the perinatal period.

Abstract

Context
Adrenocortical carcinoma (ACC) is a rare endocrine malignancy with overall poor prognosis. The Ki67 labeling index (LI) has a major prognostic role in localized ACC after complete resection, but its estimates may suffer from considerable intra- and interobserver variability. VAV2 overexpression induced by increased Steroidogenic Factor-1 dosage is an essential factor driving ACC tumor cell invasion.

Objective
To assess the prognostic role of VAV2 expression in ACC by investigation of a large cohort of patients.

Design, Setting, and Participants
A total of 171 ACC cases (157 primary tumors, six local recurrences, eight metastases) from seven European Network for the Study of Adrenal Tumors centers were studied.

Outcome Measurements
H-scores were generated to quantify VAV2 expression. VAV2 expression was divided into two categories: low (H-score, &lt;2) and high (H-score, ≥2). The Ki67 LI retrieved from patients' pathology records was also categorized into low (&lt;20%) and high (≥20%). Clinical and immunohistochemical markers were correlated with progression-free survival (PFS) and overall survival (OS).

Results
VAV2 expression and Ki67 LI were significantly correlated with each other and with PFS and OS. Heterogeneity of VAV2 expression inside the same tumor was very low. Combined assessment of VAV2 expression and Ki67 LI improved patient stratification to low-risk and high-risk groups.

Conclusion
Combined assessment of Ki67 LI and VAV2 expression improves prognostic prediction in ACC.
Using trust degree for agents in order to assign spots in a Smart Parking
Authors: Souza De Castro Lucas Fernando , Vaz Alves Gleifer , Pinz Borges André 
Published: July 2017

The process of looking a spot could be a problem. There are computing solutions being developed to optimize this problem. One of these solutions is using multiagent systems (MAS). In this paper, a MAS is developed in order to allocate spots in a smart parking using the framework JaCaMo. This paper comprises of two types of agents: manager and drivers. The manager is responsible for administrating the parking spots which will be assigned to drivers according to a corresponding degree of trust. The trust degree is a value which shows the commitment of the driver before the manager. In order to verify the effectiveness of the MAS, several simulations were conducted in empirical scenarios. Experiments show that the degree of trust impacts in the parking spot allocation process.
Experimenting with Novel Socio-Technical Configurations
Authors: Hielscher Sabine 
Published: July 2017

Abstract
Grassroots digital fabrication workshops (such as FabLabs), and associated technologies (such as 3D printers), are attracting increasing attention as a potential source for addressing a variety of social and environmental challenges. Through an analysis of an in-depth case study on FabLabs, this paper aims to provide insights into the practices emerging in these workshops and realities of the relationship between its members and technologies that are currently under-researched. It does this by drawing upon the domestication literature that concerns itself with how people use, adapt and reject technologies and integrate them into their life. The paper examines the significance of the interactions between people and technologies in FabLabs and offers concluding reflections on the role of these relationships within broader social and environmental changes.
Hacking Together Globally
Authors: Hunsinger Jeremy 
Published: July 2017

Abstract
This paper examines events that occur synchronously around the globe at hackerspaces: during Global Synchronous Hackathons, participants use video streams to share experiences, work and interact in real time. This paper analyses synchronous hackathons through video repositories of these events. It aims at discerning what norms are enacted in presented hacking experiences and how those norms are communicated across the video streams. Hacking in these cases should be thought of as the creative activity of using technology to build something that solves a problem or challenge. Hackerspaces are social workshops and communities renting a physical space and usually interacting in digital spaces. In these environments, individuals are involved in hacking as combined social as well as solitary activities which, to some extent, embody certain norms. Individuals also create the “technological drama”; that is they create the discourse around the objects that inform their use and embed them in cultures. These cultures and their discourses possess norms which flow through them and exist around the objects. Members of hackerspaces commonly participate in the aforementioned “Synchronous Hackathons.” By comparing videos of these hackathons, I stress the relevance of norms which are not usually listed in reflections on hacker ethics such as those of Steven Levy or Pekka Himmanen: the awareness of the global other or the awareness of what might be termed “the cosmopolitical.” These norms seek to care for and attend to the people who exist at a distance. This transformation of local to global “hacker ethics” demonstrates the growth of the recognition, at least internally, that hackerspaces embody more than their local concerns: they are part of global movements with global interests and globalising norms. The video analysis is used to demonstrate the globalising norms of these communities as the norms surrounding cosmopolitics become more prevalent in their discourses.
“Just Do It!”
Authors: Dahm Sebastian 
Published: July 2017

Abstract
In this paper I present an ethnographic approach to the research of hackerspaces. It draws upon an ethnomethodological background in order to address the role of members’ skills and knowledge. To that end, I aim for an immersive ethnographic approach in order to achieve a first-hand understanding of members’ practices. In this, I draw upon ethnomethodology as it provides a rich theoretical and methodological background for the study of skill and knowledge, namely the call for practical knowledge as an analytical instrument (Garfinkel 2006). In order to fully understand the implications of social movements like hacking and making communities, appropriate research methods are called for. Ethnomethodology, with its tradition in the analysis of epistemic practices and embodied knowledge, can provide the means for a more immersive and reflexive ethnography. By using materials of my own ethnography, I demonstrate how active engagement with members’ practices can provide for a deeper ethnographic understanding. In order to overcome the challenges of the field, I chose to adopt a project of coding myself. This acquisition of field-specific knowledge proved to be not only a valuable resource for the ongoing fieldwork but could offer important analytical insights in itself. I will show that important facets of members’ meanings were accessible only through personal experience. I suggest a broader adoption of ethnomethodological principles in ethnographic research of hackerspaces as it accommodates the underlying affinity towards experimentation prevalent in the field.
Making with China
Authors: Marshall Justin , Rossi Catharine 
Published: July 2017

Abstract
In January 2015, Li Keqiang visited Chaihuo makerspace in Shenzhen, the Chinese city that is the world’s electronics manufacturing capital. The visit expressed the significance of China’s fledgling but fast-growing maker movement: while its first makerspace was set only up in 2010, in 2016 there are over a hundred, and Keqiang’s visit is part of a bigger governmental push on makerspaces, positioned as sites of creative and technology-led innovation key to the country’s economic growth. Amidst growing research into the social, politicoeconomic and cultural significances of makerspaces in the UK and Europe, the specificity of China’s maker movement remains underresearched. Yet understanding the on-the-ground lived experience, rather than the promotional rhetoric, of China’s maker movement is crucial to its future: while lots of makerspaces are opening, many lack makers, and there are fears that China’s maker movement is an artificially fuelled bubble about to burst. Contemporaneously, the future of other types of making in China, such as its craft traditions, urban manufacturing networks, and shanzhai production, is being threatened by an assemblage of fiscal and state forces. Investigating China’s maker movement was the focus of two British-based and British-funded network, research and knowledge exchange projects in which the authors participated during 2015 and 2016: Living Research: Making in China and China’s Creative Communities: Making Value and the Value(s) of Making. This paper considers their research methodologies and initial findings. Specifically, it focuses on the craft-based participatory methodology developed in China’s Creative Communities, as seen in a “Digital Craft” workshop. Informed by social anthropology, its empirical, immersive and inclusive approach gave a voice to makers themselves. While still in a developmental stage, we believe this “craft anthropology” approach has value for future research into the maker movement in China and in other cultures and contexts.
Urban Hacking and Its “Media Origins”
Authors: Krewani Angela 
Published: July 2017

Abstract
This essay traces the genealogy of urban and mobile media hacking. It is argued that the forerunners of urban hacking were artists active within the Fluxus scene and Viennes Actionism. Their artistic practices can be seen as precursors for more recent interventions in public and particular urban spaces which have been described as “urban hacking.” These developments appear genealogically and are also related to a turn towards individual media production: the introduction of the Portapak video camera brought about grassroots media activism and influenced the institutionalisation of public television.
Identity Crisis in the Pearl River Delta

Published: July 2017

Abstract
This paper is a conversation-based reflection on hacker-, maker- and DIY-culture. It focuses on the unique cultural and socio-economic setting of Hong Kong, using Dim Sum Labs, its first hacker/makerspace as its primary subject of investigation. To provide context, we begin with an outline of the cultural, economic and physical challenges presented by Hong Kong. We then proceed to present and relay conversation pieces from interviews with members and non-members of Dim Sum Labs, who speak about their respective perspectives on notions of “hacking,” “making” and “DIY-culture.” Finally, we provide some reflections on our own experiences as members of the hacker/maker/ DIY-culture and past directors of Dim Sum Labs.
Surveillance of bacterial colonisation on contact surfaces in different medical wards
Authors: Torkar Karmen Godič , Ivić Sanja 
Published: July 2017

Abstract
This study was conducted to determine the bacterial colonization of some bacterial groups, including extended-spectrum β-lactamase (ESBLs) producers and methicillin-resistant Staphylococcus aureus (MRSA), on surfaces of the equipment and instruments in patient rooms and other workspaces in three different medical wards. The number of microorganisms on swabs was determined with the colony count method on selective microbiological mediums. The aerobic mesophylic microorganisms were found in 73.5 % out of 102 samples, with the average and maximum values of 2.6 × 102 and 4.6 × 103 colony forming units (CFU) 100 cm-2, respectively. Members of the family Enterobacteriaceae, coagulase positive staphylococci, coagulase-negative staphylococci, and enterococci were detected in 23.4, 31.4, 53.2, and 2.9 % of samples, respectively. The differences in bacterial counts on the surfaces of the psychiatric, oncology, and paediatric wards were statistically significant (P<0.001). About 40 % out of 19 isolates from the family Enterobacteriaceae showed multiple resistance to three or more different groups of tested antibiotics, while ESBL was confirmed for only one strain. Staphylococci isolates were mostly resistant to penicillin. MRSA was confirmed in 5.2 % of the tested S. aureus isolates. Greater attention should be paid to cleaning and the appropriate choice of disinfectants, especially in the psychiatric ward. Employees should be informed about the prevention of the spreading of nosocomial infections. Routine application of rapid methods for hygiene control of surfaces is highly recommended.
Kirchhoff–Hardy Fractional Problems with Lack of Compactness
Authors: Fiscella Alessio , Pucci Patrizia 
Published: July 2017

Abstract
This paper deals with the existence and the asymptotic behavior of nontrivial solutions for some classes of stationary Kirchhoff problems driven by a fractional integro-differential operator and involving a Hardy potential and different critical nonlinearities. In particular, we cover the delicate degenerate case, that is, when the Kirchhoff function M is zero at zero. To overcome the difficulties due to the lack of compactness as well as the degeneracy of the models, we have to make use of different approaches.

Abstract
The aim of the study was to assess the hearing threshold levels (HTLs) in employees exposed to noise generated by low-frequency ultrasonic technological equipment in comparison with the HTLs of workers exposed to audible noise at the similar A-weighted equivalent-continuous sound pressure level. The study includes measurements of ultrasonic and audible noise at workplaces and hearing tests, i.e. conventional pure-tone audiometry and extended high-frequency audiometry. The study group comprised 90 workers, aged 41.4±10.0 years (mean±SD), exposed for 17.3±9.8 years to noise generated by ultrasonic devices at mean daily noise exposure level (‹LEX,8h›) of 80.6±2.9 dB. The reference group consists of 156 subjects, exposed to industrial noise (without ultrasonic components) at similar A-weighted equivalent-continuous sound pressure level (‹LEX,8h› = 81.8±2.7 dB), adjusted according to age (39.8±7.7 years), gender and job seniority (14.0±7.0 years). This group was selected from database collected in the Nofer Institute of Occupational Medicine. Audiometric hearing threshold levels in the frequency range of 0.5-6 kHz were similar in both groups, but in the frequency range of 8-12.5 kHz they were higher in the group of employees exposed to ultrasonic noise. The findings suggest that differences in the hearing threshold (at high frequencies) in analyzed groups may be due to differences in spectral composition of noise and show the need to continue the undertaken studies.

Published: July 2017

Abstract

Background:
The Sysmex DI-60 system (DI-60, Sysmex, Kobe, Japan) is a new automated digital cell imaging analyzer. We explored the performance of DI-60 in comparison with Sysmex XN analyzer (XN, Sysmex) and manual count.

Methods:
In a total of 276 samples (176 abnormal and 100 normal samples), white blood cell (WBC) differentials, red blood cell (RBC) classification and platelet (PLT) estimation by DI-60 were compared with the results by XN and/or manual count. RBC morphology between pre-classification and verification was compared according to the ICSH grading criteria. The manual count was performed according to the Clinical and Laboratory Standards Institute guidelines (H20-A2).

Results:
The overall concordance between DI-60 and manual count for WBCs was 86.0%. The agreement between DI-60 pre-classification and verification was excellent (weighted κ=0.963) for WBC five-part differentials. The correlation with manual count was very strong for neutrophils (r=0.955), lymphocytes (r=0.871), immature granulocytes (r=0.820), and blasts (r=0.879). RBC grading showed notable differences between DI-60 and manual counting on the basis of the ICSH grading criteria. Platelet count by DI-60 highly correlated with that by XN (r=0.945). However, DI-60 underestimated platelet counts in samples with marked thrombocytosis.

Conclusions:
The performance of DI-60 for WBC differential, RBC classification, and platelet estimation seems to be acceptable even in abnormal samples with improvement after verification. DI-60 would help optimize the workflow in hematology laboratory with reduced manual workload.

Enhancing Fingerprint Image Recognition Algorithm Using Fractional Derivative Filters
Authors: Baloochian Hossein , Ghaffary Hamid Reza , Balochian Saeed 
Published: July 2017

Abstract
One of the most important steps in recognizing fingerprint is accurate feature extraction of the input image. To enhance the accuracy of fingerprint recognition, an algorithm using fractional derivatives is proposed in this paper. The proposed algorithm uses the definitions of fractional derivatives Riemann-Liouville (R-L) and Grunwald-Letnikov (G-L) in two sections of direction estimation and image enhancement for the first time. Based on it, new mask of fractional derivative Gabor filter is calculated. The proposed fractional derivative-based method enhances the image quality. This method enhances the structure of ridges and grooves of fingerprint, using fractional derivatives. The efficiency of the proposed method is studied in images of FVC2004 (DB1, DB2, DB3 and DB4) database and the results are evaluated using the criteria including entropy, average gradient, and edge intensity. Also, performance of the proposed method is compared with other technical methods such as Gabor filter. Based on the obtained results from the tests, the method is able to enhance the quality of fingerprint images significantly.
Unit Cell Modelling and Simulation of All Vanadium Redox Flow Battery

Published: July 2017

AbstractVanadium redox flow battery (VRFB) is one of the promising technologies for large scale renewable energy storage due to its long life time and flexible design. Electrolyte flow rate, electrolyte concentration, electrode porosity, temperature and applied magnitude of current have significant effect on the efficiency of VRFB. In the present work, a simplified dynamic lumped parameter model is developed in MATLAB to provide accurate results at unit cell level which can be used to control and optimize the parameters. The proposed model is based on the mass balance and charge conservation of various vanadium species and hydrogen ion concentration in the electrolyte. Major losses such as ohmic losses and activation losses are included in the cell potential. Recirculation of the electrolyte through external reservoirs is also considered. Numerical simulation demonstrates the effect of change in initial vanadium concentration and operating temperature on unit cell performance. It is shown that variations in electrolyte flow rate, magnitude of applied current substantially alter the charge/discharge characteristics and efficiency.

Published: July 2017

Abstract
The paper deals with the family of irreducible left truncation invariant bivariate copulas, which admit a nontrivial lower tail dependence function. Such copulas, similarly as the Archimedean ones, are characterized by a functional parameter, a generator being an increasing convex function.We provide a nonparametric, piece-wise linear estimator of such generators.
The relationship with the Other as a platform for discussion about conflicts. Comments on the Orzesze coal mine project
Authors: Belzyt Joanna Iza 
Published: July 2017

Abstract
An analysis was made of comments in media reports on the selected case, the „Orzesze” mining project, posted by Internet users on news websites during the period July 2014 - December 2016 This article is an attempt to examine the relationship with the Other/Alien when thinking about conflicts around investment projects which will interfere with the surrounding social and natural environment. The article considers the theories on the sources of conflict and the development of the conflict process and its consequences and suggests possible courses of action to prevent the escalation of such conflicts particularly with respect to the “Orzesze” mining project in the Upper Silesia, Poland. Taking into account that the Data, Relationship, Value, and Interest conflicts can all be sources of conflict, it should be underlined that good social communication is extremely important in the prevention and resolution of conflicts and the mitigation of their destructive influence. In a cooperation/communication oriented environment it would be much easier to focus on finding solutions rather than finding the guilty party as this can lead to an escalation of the conflict as searching for the guilty party is inextricably linked with the desire to win or to take revenge.
