Building of Academics’ Networks—An analysis based on Causation and Effectuation theory
Authors: Ahoba-Sam Rhoda , Charles David 
Published: September 2019

Abstract
Individual academic scientists engage in various collaborations through their involvement in both regional and extra-regional networks. However, little is known about how these networks are actually formed. Focusing on university and industry networks, we take the view that the process of building new networks is an entrepreneurial activity that involves unpredictability and often goal ambiguity. This paper thus employs the theories of causation and effectuation to explore how the personal networks of academics are initiated. With evidence from the networks of 12 academics based at the University of Stavanger, Norway we show that both causation and effectuation are employed by academics when building their networks. The usage of causation was found to be more consistent with building industry networks whereas effectuation was employed when building networks in academia. Consequently, effectuation was characteristic of the international networks which were found to be mostly constituted by other academics. On the regional level, a mixture of both approaches of causation and effectuation was observed, with more industry linkages suggesting a tendency to be more causal than effectual. Furthermore, while causation was employed for project level networking, effectuation was employed for establishing more individual level ties.
A Proof of the Bloch Theorem for Lattice Models
Authors: Watanabe Haruki 
Published: September 2019

Abstract
The Bloch theorem is a powerful theorem stating that the expectation value of the U(1) current operator averaged over the entire space vanishes in large quantum systems. The theorem applies to the ground state and to the thermal equilibrium at a finite temperature, irrespective of the details of the Hamiltonian as far as all terms in the Hamiltonian are finite ranged. In this work we present a simple yet rigorous proof for general lattice models. For large but finite systems, we find that both the discussion and the conclusion are sensitive to the boundary condition one assumes: under the periodic boundary condition, one can only prove that the current expectation value is inversely proportional to the linear dimension of the system, while the current expectation value completely vanishes before taking the thermodynamic limit when the open boundary condition is imposed. We also provide simple tight-binding models that clarify the limitation of the theorem in dimensions higher than one.

Published: September 2019

Abstract
Background People with visual impairment often report poorer health and encounter many challenges when using medicines. Pharmacists can play a significant role in optimising medicines use for these patients. However, little is known about pharmacists’ current practices when providing services to this population nor the impact of such services, if any, on medicines optimisation-related outcomes. Aim of the review This systematic review aims to identify the types, and assess the effectiveness of, interventions provided by pharmacists on medicines optimisation-related outcomes. Method Systematic searches of the following electronic databases were carried out from date of inception to March 2018: Cochrane Library; MEDLINE; EMBASE; International Pharmaceutical Abstracts; Scopus; and Cumulative Index to Nursing and Allied Health Literature. Several trial registries and grey literature resources were also searched. Any randomised controlled trials, non-randomised controlled trials, controlled before-and-after studies, or interrupted time series analyses reporting on interventions provided by pharmacists to adult visually impaired patients and/or their caregivers in order to improve medicines optimisation-related outcomes of medicine safety, adherence, patient satisfaction, shared decision making, or quality of life were included. Results A total of 1877 titles/abstracts were screened, and 27 full text articles were assessed for eligibility. On examination of full texts, no studies met the inclusion criteria for this review. Conclusion This review highlights the need for future research that would be vital for promoting the safe and effective use of medicines and the delivery of pharmaceutical care services to people with visual impairment.

Abstract
In recent years, the German Aerospace Center (DLR) developed Gossamer deployment systems in different projects. As power requirements of spacecraft are getting more and more demanding, DLR recently focused on the development of new deployable photovoltaic (PV) technologies that are suitable for generating 10’s of kW per array. Possible space applications that may also require high power supply are missions using electric propulsion such as interplanetary missions, placing of geostationary (GEO) satellites in their orbit or even more future oriented as space tugs or lightweight power generation on extra-terrestrial infrastructures. The paper gives an overview about a feasibility study for flexible solar arrays based on new thin-film photovoltaics. It is expected that the combination of new thin-film PV technologies, e.g., copper indium gallium selenide (CIGS) cells or gallium–arsenide (GaAs) cells, together with Gossamer deployment technologies, could significantly increase the power availability for spacecraft. Based on a requirement, analysis system concepts were evaluated. A focus is on the potential of CIGS PV combined with a two-dimensional deployment of the array and DLR’s coilable carbon fibre-reinforced plastic (CFRP) booms. Therefore, a concept based on crossed booms with a foldable PV membrane is considered as baseline for further developments. The array consists of rectangular PV generators that are interconnected by flexible printed circuit board (PCB) harness. By a double-folding technique, these generators are laid on top of each other in such that the membrane can be extracted from its stowing box during the deployment in a controlled manner. Considering constantly increasing efficiencies of the CIGS PV combined with Gossamer structures, there is clear potential of reaching a very high specific power value exceeding that of conventional PV systems. Furthermore, the CIGS PV appears to be more radiation resistant and has already reached more than 21% efficiency in laboratories. Such efficiencies are expected to be achieved in the near future in a standard manufacturing process. However, flexible, thin-film GaAs cells are also subject of consideration within GoSolAr. With this prospect, DLR’s research has the goal to develop a Gossamer Solar Array (GoSolAr) to exploit the described potential.
Understanding the morphology of MWCNT/PES mixed-matrix membranes using SANS: interpretation and rejection performance
Authors: Nikita Km , Karkare P. , Ray D. , Aswal V. K. , Singh Puyam S. , Murthy C. N. 
Published: September 2019

Abstract
We describe the relationship between the morphology and rejection performance by the mixed-matrix membranes as a unique class of high water flux nanofiltration membranes comprising polyethersulfone/functionalized multiwalled carbon nanotubes (PES/f-MWCNTs). These membranes contain aligned MWCNTs uniformly distributed inside a PES matrix prepared using conventional phase-inversion technique. The small-angle neutron scattering analysis confirmed the high porosity and uniformity among of the pores of CNTs in the membranes. The frictionless water transport from vertically oriented f-MWCNTs were verified to facilitate remarkable enhancement in the water flux through the membranes. The water transportation speed, as well as rejection, of selected heavy metals increases nearly about 3 times and 2–3.5 times, respectively, than the pristine PES membrane, depending upon CNTs loading. Low working pressure and good retention properties make these membranes to be an ideal for the application of highly efficient filtration units.
Impact of Economic Development Levels and Disaster Types on the Short-Term Macroeconomic Consequences of Natural Hazard-Induced Disasters in China

Published: September 2019

AbstractThe relationship between natural hazard-induced disasters and macroeconomic growth has been examined widely on global and national scales, but little research has been focused on the subnational level, especially in China. We examined the impacts of natural hazard-induced disasters on the regional growth in China based on subnational panel data for the period from 1990 to 2016. First, we used the number of people affected and the direct economic losses as the measures of the scale of disasters. Then, we used the direct damages of meteorological disasters and earthquakes as disaster measures separately to examine the impacts of different disaster types. Finally, we performed intraregional effects regressions to observe the spatial heterogeneity within the regions. The results show that the adverse short-term effects of disasters is most pronounced in the central region, while the direct damage of disasters is a positive stimulus of growth in the whole of China. However, this stimulus is observed in a lagged way and is reflected differently—meteorological disasters in central and eastern China and earthquakes in western China are related to regional growth. The results demonstrate that the short-term macroeconomic impacts of these disasters in the three geographical regions of China largely depend on regional economic development levels and the disaster types.

Published: September 2019

Purpose To review the computed tomography and magnetic resonance imaging manifestations of acute and chronic renal infections that may mimic malignancy and to provide useful tips to establish an imaging diagnosis. Conclusion Acute and chronic bacterial pyelonephritis are usually readily diagnosed clinically and on imaging when the diagnosis is suspected based upon clinical presentation. When unsuspected, focal, extensive or mass-like, acute and chronic bacterial pyelonephritis may mimic infiltrative tumours such as urothelial cell carcinoma (UCC), lymphoma, and metastatic disease. Infection may be suspected when patients are young and otherwise healthy when there is marked associated perinephric changes and in the absence of metastatic adenopathy or disease elsewhere in the abdomen and pelvis. Renal abscesses, from bacterial or atypical microbial agents, can appear as complex cystic renal masses mimicking cystic renal cell carcinoma. Associated inflammatory changes in and around the kidney and local invasion favour infection. Emphysematous pyelonephritis can mimic necrotic or fistulizing tumour; however, infection is more likely and should always be considered first. Xanthogranulomatous pyelonephritis can mimic malignancy when focal or multifocal and in cases without associated renal calculi. Malacoplakia is an inflammatory process that may mimic malignancy and should be considered in patients with chronic infection. Bacillus Calmette-Guerin (BCG)-induced pyelonephritis is rare but can mimic renal malignancy and should be considered in patients presenting with a renal mass when being treated with BCG for urinary bladder UCC.

Abstract

Introduction
The comorbidity between premature ejaculation (PE) and erectile dysfunction (ED) has not yet been clarified.

Aim
To assess the comorbidity between PE and ED.

Methods
Male members of a shopping club in Taiwan aged 20–60 years with stable sexual relationships were invited to complete an online questionnaire.

Main Outcome Measures
Self-estimated intravaginal ejaculatory latency time (IELT), Premature Ejaculation Diagnostic Tool, Sexual Health Inventory for Men, Self-Esteem and Relationship, and Hospital Anxiety and Depression Scale results were used.

Results
A total of 937 participants with a mean age of 41.1 ± 10.2 years were enrolled. The prevalence rates of ED (Sexual Health Inventory for Men ≤ 21), PE (Premature Ejaculation Diagnostic Tool ≥11), and IELT ≤1 minute were 24.7%, 6.3%, and 6.4%, respectively. Prevalence of acquired PE and IELT ≤1 minute increased marginally with age. Participants with ED had a greater prevalence of PE than those without ED (19.5% vs 2.0%, P &lt; .001), and participants with PE had a greater prevalence of ED than those without PE (76.3% vs 19.4%, P &lt; .001). Compared with participants without PE, participants with PE had greater adjusted odds of ED (odds ratio [OR] = 12.7, 95% CI = 6.7–24.2). Relative to participants without ED, participants with ED had increased adjusted odds of PE (OR = 7.2, 95% CI = 3.5–14.6 with mild ED and OR = 36.7, 95% CI = 16.2–83.0 with ED severity greater than a mild degree). Poor sexual relationships and self-esteem, depression, and anxiety were reported more frequently in those with PE or ED, especially in those with both problems compared with those without PE and ED.

Conclusions
This study confirmed a high prevalence of PE and ED coexistence, indicating a complicated relationship between the 2 conditions and the importance of screening for their co-occurrence in practice.

Authors: Dove Erica , Astell Arlene J. 
Published: September 2019

AbstractIntroductionMotion‐based technologies (MBTs) could provide nonpharmacologic interventions for people with cognitive impairment (PCI; e.g., dementia or mild cognitive impairment). This study examined the use of errorless learning techniques to empower PCI to use MBT.MethodsThirty‐eight PCI were recruited to a 10‐week (20 × 1‐hour sessions) Xbox Kinect bowling group. Video recorded data from first, middle, and final sessions were coded to track (1) number of prompts per turn, (2) independent turn completion, and (3) duration of turns. These values were compared using repeated measures analysis of variance.ResultsLearning and improvement over time was demonstrated in 23 participants who were available for final analysis by significant decreases in number of prompts per turn and turn duration and significant increases in turns completed independently.DiscussionErrorless learning supported PCI to learn MBT and improve over time as evidenced by their need for fewer prompts, shorter turns, and more turns completed independently, confirming the potential of MBT to provide leisure activities for PCI.

Published: September 2019

ABSTRACTOrigami, the ancient paper folding art has inspired the engineering equipment and design for decades. The basic concept of origami is very general, which leads to applications ranging from small scale to large scale. Recently, researchers are interested in being able to create self-folding structures. Such a structure enables kinematic manipulation by external forces or moments without folding and/or unfolding operations. This is a beneficial application for many fields including aerospace systems, robots, small devices and self-assembly systems. In this paper, the investigation and analyses of the previous literatures on the key driving force of the actuation structure, including the heat, light, electricity, gas and other actuation methods. The aims are to provide researchers and practitioners with the support to systematically understand the latest technologies in this important and evolving field, with inspiration and direction for follow-up.
Looking Back at Milošević’s Antibureaucratic Revolution: What Do Ordinary Participants Now Think of Their Involvement?
Authors: Grdešić Marko 
Published: September 2019

AbstractMost scholarship on Serbia’s antibureaucratic revolution of the late 1980s has emphasized elite actors while ignoring the motivations of ordinary participants. How do ordinary people describe their involvement? Moreover, given the antibureaucratic revolution’s dark side—such as exclusionary nationalism and political authoritarianism—it is important to investigate whether participants are willing to critically engage their personal political histories. What do they now say about their roles in this episode? In order to provide answers to this question, six focus groups with a total of 34 participants were organized in the town of Novi Sad, the location of one of the best-known rallies of the antibureaucratic revolution, the so-called yogurt revolution. Most people see their involvement in a rather negative way and regret taking part. However, two blind spots also appear that lessen their sense of personal responsibility: conspiracy theories and notions of urban superiority. The former shifts blame onto secret forces and the latter onto nonurban outsiders. Overall, the long-term legacies of the antibureaucratic revolution are negative: they are associated with cynicism and apathy.
Revolutionary Origins of Political Regimes and Trajectories of Popular Mobilization in the Late Communist Period
Authors: Vladisavljević Nebojša 
Published: September 2019

AbstractPopular protest, which repeatedly occurred in Communist regimes, turned into massive mobilizational waves in the late Communist period. Why did some protests result in state cooptation and particularist nationalism (Yugoslavia and the Soviet Union), and others in state-society polarization (Poland) and protest containment (China), when these states shared important historical, political, and institutional legacies? Political regimes with origins in indigenous popularly-based revolutionary movements are more resilient to popular protests and other major crises than other authoritarian regimes. Protracted ideological armed struggle largely overlaps with broader patriotic causes, such as liberation wars or struggles against foreign intervention. The revolutionary regimes thus acquire patriotic credentials, while boundaries between partisan and patriotic identities become blurred, which strengthens their elite unity and popular base. Popular protests thus facilitate a complex political game of old and new actors that may result in regime survival or transformation. In other regimes, popular unrest tends to produce state-society polarization and, ultimately, regime delegitimation and breakdown. Popular contention in complex multinational institutional settings, if there is no major external threat, highlights old and triggers new conflicts along these structural and institutional divides and, where dual political identities prevail, facilitates identity shifts in particularist direction.

Published: September 2019

AbstractOn low-input smallholder farms of Kenyan upland landscapes, erosion of nutrient-rich topsoil strongly affects crop yields. Where maize (Zea mays) is intercropped on erosion-prone slopes, intercropping can potentially reduce soil erosion. The objective of this research was to quantify the contribution of crops and crop mixtures of different growth habits to erosion control and their influence on above-ground biomass and earthworm abundance as indicators of soil function in smallholder farming systems under a bimodal rainfall pattern in Western Kenya. The experiment involved five treatments, namely maize (Z. mays)/common bean (Phaseolus vulgaris) intercrop (maize intercrop), maize/common bean intercrop plus Calliandra (Calliandra calothyrsus) hedgerows and Calliandra mulch (Calliandra), sole Lablab (Lablab purpureus), sole Mucuna (Mucuna pruriens) and groundnut (Arachis hypogaea) intercropped with maize (during the short rains). The experiment was conducted over three consecutive cropping seasons and the cropping system had significant effects on soil loss, runoff, water infiltration, earthworm abundance and above-ground biomass and crop grain yield. The Calliandra treatment had the lowest runoff (11.6–17.2 mm ha−1) and soil erosion (31–446 kg ha−1 per season) in all the seasons, followed by the Mucuna treatment. Lablab was affected by disease and showed the highest soil erosion in the last two seasons. Infiltration was highest in Calliandra treatment, and earthworm abundance was higher under Mucuna and Calliandra treatments (229 and 165 earthworms per square metre, respectively) than under other crops. Our results suggest that including sole crops of herbaceous species such as Mucuna, or tree hedgerows with mixtures of maize and grain legumes has the potential to reduce runoff and soil erosion in smallholder farming. Additionally, these species provide a suitable habitat for earthworms which stabilise soil structure and macropores and thus potentially increase infiltration, further reducing soil erosion.
The Revolutionary City: Socialist Urbanisation and Nuclear Modernity in Cienfuegos, Cuba
Authors: Cederlöf Gustav 
Published: September 2019

AbstractDuring the Cold War, Havana symbolised the struggle for national liberation in Latin America. Yet in few other places on the island of Cuba did the Revolution's visions of development materialise as they did in the southern city of Cienfuegos. This article examines why two half-finished nuclear reactors and a decaying ‘nuclear city’ still remain in Cienfuegos. Through a comprehensive spatial and infrastructural transformation of Cuba, the revolutionary government sought to remedy the evils of dependency and unequal exchange. Cienfuegos, and its shifting place in the Cold War political economy, demonstrates how a radical critique of urbanisation merged with the spatiality of centralised energy infrastructure in the pursuit of ultimately-failed nuclear modernity. The history of Cienfuegos draws the academic gaze away from Latin America's major cities to broaden the ‘geographies of theory’ in urban, energy and Latin American studies.
