Global sustainable city-regions: Stockholm, Berlin, Kolkata, Abu Dhabi/Masdar, Bengaluru, Malawi, Belfast, Hong Kong, Seoul, Helsinki, & Scotland

This policy report, entitled ‘Global Sustainable City-Regions,’ covers the work developed by the lecturer, Dr Igor Calzada, MBA, FeRSA, as the editor of the publica- tion and students of the second edition of the Master course MSc in Leadership for Global Sustainable Cities from September to December 2016. Specifically, this policy report follows a two-sequential-module structure: • The first module, entitled ‘Global Cities: Sustainability and Society,’ consists of six methodological units. • Thereafter, the second module, entitled ‘Public Policy, Governance and Strategic Change in Cities,’ consists of five methodological units. The policy report focuses on three urban global issues in a comparative basis. The MSc was developed in a team-based dynamic by applying qualitative action research methodologies to understand and interpret each case and to benchmark and contrast with other cases that addressed the same global urban issue. The cases were selected jointly by the lecturer and the students in a dynamic process in order to achieve a suitable selection of cases that would allow them to: • arrange groups around one specific global urban issue, • compare cases around the same specific urban issue, and • produce a full case study by applying the two-sequential-module methodology. • Transformative Smart Cities: In recent years, the smart city paradigm has gained traction in urban policy and governance. Underlying the smart city discourse is the techno-utopian belief that the use of information and communication technologies (ICTs) is imperative to confront the challenges of urbanization and sustainable development. Although, little has been researched about the differences between this paradigm and its consequences in the Global South and in the Global North. In addition to this, since the smart city as a buzzword has conquered policy agendas worldwide, a transformational push is occurring in some innovative cities and regions worldwide. This urban issue called ‘Transformative Smart Cities’ is explained comparatively through five cases as follows: Stockholm, Kolkata, Masdar, Bengaluru, and Seoul. • Changing Social Innovation: Urban issues are usually complex and interconnected phenomena. Poverty, political conflicts, environmental awareness, mobility and transport mechanisms, geopolitical path-dependence, ethno-political unrest, digital connectivity and self-determination could be researched from the social innovation changing perspective. The capacity to think across and between as well as within the thematic factors is crucial. Likewise, a clear understanding of the way in which different disciplines can contribute to a step change in delivery against these changing challenges is therefore required. Ultimately, an awareness of the underlying factors and contexts (including social, political, economic, cultural, technological and historial), interdependencies, synergies, tensions and trade-offs that promote, obstruct or even reverse delivery against social innovation, both individually and collectively are key to understand changing dynamics in city-regions. This urban issue called ‘Changing Social Innovation’ is explained comparatively through six cases as follows: Berlin, Belfast, Malawi, Hong Kong, Helsinki, and Glasgow

Scopolamine Administration Modulates Muscarinic, Nicotinic and NMDA Receptor Systems

Studies on the effect of scopolamine on memory are abundant but so far only regulation of the muscarinic receptor (M1) has been reported. We hypothesized that levels of other cholinergic brain receptors as the nicotinic receptors and the N-methyl-D-aspartate (NMDA) receptor, known to be involved in memory formation, would be modified by scopolamine administration

Effects of methylphenidate on attention in Wistar rats treated with the neurotoxin N-(2-chloroethyl)-N-ethyl-2-bromobenzylamine (DSP4)

The aim of this study was to assess the effects of the neurotoxin N-(2-chloroethyl)-N-ethyl-2-bromobenzylamine (DSP4) on attention in rats as measured using the 5-choice-serial-reaction-time task (5CSRTT) and to investigate whether methylphenidate has effects on DSP4-treated rats. Methylphenidate is a noradrenaline and dopamine reuptake inhibitor and commonly used in the pharmacological treatment of individuals with attention deficit/hyperactivity disorder (ADHD). Wistar rats were trained in the 5CSRTT and treated with one of three doses of DSP4 or saline. Following the DSP4 treatment rats were injected with three doses of methylphenidate or saline and again tested in the 5CSRTT. The treatment with DSP4 caused a significant decline of performance in the number of correct responses and a decrease in response accuracy. A reduction in activity could also be observed. Whether or not the cognitive impairments are due to attention deficits or changes in explorative behaviour or activity remains to be investigated. The treatment with methylphenidate had no beneficial effect on the rats’ performance regardless of the DSP4 treatment. In the group without DSP4 treatment, methylphenidate led to a reduction in response accuracy and bidirectional effects in regard to parameters related to attention. These findings support the role of noradrenaline in modulating attention and call for further investigations concerning the effects of methylphenidate on attentional processes in rats

Ultrasound backscattering outperforms the clinically used ultrasound parameters in discrimination of osteoporotic-like human trabecular bone samples

New quantitative ultrasound techniques have been introduced for the assessment of bone quality. The aim of this study was to investigate the sensitivity of current clinically used ultrasound parameters and novel backscatter parameters on discrimination of osteoporotic-like human trabecular bone samples from normal samples. Moreover, the effect of ultrasound (US) frequency on measured parameters was investigated. In this study, 16 human trabecular samples were measured in transmission and pulse-echo geometry in vitro. Moreover, structural characteristics (microCT measurements) and mechanical properties (destructive compressive testing) were determined. The samples were divided into two groups (osteoporotic-like, normal) based on the porosity of the samples. Mechanical properties between selected groups differed significantly (

Dual-Frequency Ultrasound-New Pulse-Echo Technique for Bone Densitometry

Quantitative ultrasound has been suggested for screening of osteoporosis. Most commercial ultrasound devices are based on the through-transmission measurement of calcaneus, which is not a typical fracture site. In contrast to through-transmission measurements, reflection and backscattering measurements may be conducted at typical fracture sites such as vertebra and proximal femur. At these regions, soft tissues overlying bones affect reliability of the measurements. In this study, a novel dual-frequency ultrasound (DFUS) pulse-echo technique is introduced for reduction of the errors induced by soft tissues. First, DFUS was validated using elastomer samples. For further validation, human trabecular bone samples (n = 25) covered with heterogeneous soft tissues were measured at frequencies of 2.25 MHz and 5.0 MHz. The DFUS technique reduced (p < 0.01) the mean error induced by soft tissue from 58.6% to -4.9% and from 127.4% to 23.8% in broadband ultrasound backscattering and integrated reflection coefficient (at 5.0 MHz), respectively. To conclude, the DFUS, being the first ultrasound technique capable of determination of the composition and thickness of the soft tissue overlying the bone, may enhance the accuracy of clinical ultrasound measurements. Thereby, DFUS shows a significant clinical potential. (E-mail: [email protected])

Spatial variation of acoustic properties is related with mechanical properties of trabecular bone

In clinical applications, ultrasound parameters are measured as an average value over a region of interest (ROI) or as a value at a single measurement point. Due to natural adaptation to loading conditions, trabecular bone is structurally, compositionally and mechanically heterogeneous and anisotropic. Thus, spatial variation of ultrasound parameters within ROI may contain valuable information on the mechanical integrity of trabecular bone. However, this issue has not been thoroughly investigated. In the present study, we aimed at investigating the significance of the spatial variation of ultrasound parameters for the prediction of mechanical properties of human trabecular bone. For this aim, parametric maps of apparent integrated backscattering (AIB), integrated reflection coefficient (IRC), speed of sound (SOS), average attenuation (AA) and normalized broadband ultrasound attenuation (nBUA) were calculated for femoral and tibial bone cylinders (n = 19-20). Further, the effect of time window length on the AIB, variation of AIB within ROI and association between AIB and bone mechanical properties were characterized. Based on linear correlation analysis, spatial variation of AIB, assessed as standard deviation of measurements within ROI, was a strong predictor of bone ultimate strength (r = -0.82, n = 19, p < 0.01). Further, the time window length affected absolute values of AIB and strength of correlation between AIB and bone ultimate strength. Interestingly, linear combination of mean IRC and spatial variation of AIB within ROI was the strongest predictor of bone ultimate strength (r = 0.92, n = 19, p < 0.01). In conclusion, our findings suggest that the measurement of two-dimensional parametric maps of ultrasound parameters could yield information on bone status not extractable from single point measurements. This highlights the potential of parametric imaging in osteoporosis diagnostics

Dual-frequency ultrasound technique minimizes errors induced by soft tissue in ultrasound bone densitometry

Background: Most bone ultrasound devices are designed for through-transmission measurements of the calcaneus. In principle, ultrasound backscattering measurements are possible at more typical fracture sites of the central skeleton. Unfortunately, soft tissue overlying the bones diminishes reliability of these measurements. Purpose: To apply the single-transducer dual-frequency ultrasound (DFUS) technique to eliminate the errors induced by soft tissue on the measurements of integrated reflection coefficient (IRC) in human distal femur in vivo. Material and Methods: Ultrasound and dual-energy X-ray absorptiometry (DXA) examinations were conducted on a bodybuilder during a 21-week training and dieting period. Results: Significant changes in quantity and composition of soft tissue took place during the diet. However, DXA measurements showed no significant effects on bone density measurements. The single transducer DFUS technique enabled the determination of local soft-tissue composition, as verified by comparison with the DXA (r=0.91, n=8, p0.01). Further, the technique eliminated the soft-tissue-induced error from IRC measured for the bone. The uncorrected IRC associated significantly with the change in local soft-tissue composition (r=-0.83, n=8, p0.05), whereas the corrected IRC values showed no significant dependence (r=-0.30, n=8, p=0.46) on local soft-tissue composition. Conclusion: The DFUS technique may significantly enhance the accuracy of clinical ultrasound measurements of bone
