Cultivating food or cultivating citizens? On the governance and potential of community gardens in Amsterdam

ABSTRACT A renaissance of community gardening is unfolding on a global urban scale. Scholars have analysed community gardening projects as empowering, contested or controlled spaces depending on the local governance networks in which, or despite of which, they emerge. Focusing on the political-economic context in which gardening activities emerge in Amsterdam, we present community gardens as places where the neoliberal localisation of the city unfolds. Based on a qualitative study of 19 community gardening projects in the city of Amsterdam, we argue that community gardening projects in Amsterdam can be seen as “controlled space” [Eizenberg, E. 2012a. “Actually Existing Commons: Three Moments of Space of Community Gardens in New York City. ” Antipode 44 (3): 764–782. ]: a space where various institutional governance actors have a varied level of influence and control. Following [McClintock, N. 2014. “Radical, Reformist, and Garden-Variety Neoliberal: Coming to Terms with Urban Agriculture’s Contradictions. ” Local Environment 19 (2): 147–171. ] who argues that community gardens can be “radical and neoliberal at once” we unpack this notion of controlled space. We compare differently managed gardening projects and describe the varied relations between gardeners and four governance actors, namely local government, welfare organisations, green NGOs and housing associations. We show how these relations both impair and enable the civic participation of gardeners, the inclusive potential of gardens and an alternative, local food provision and distribution. Finally, we reflect on what this means for the potential of community gardening, a rising urban phenomenon, to (re)claim urban space.
TGNet: Geometric Graph CNN on 3-D Point Cloud Segmentation

Recent geometric deep learning works define convolution operations in local regions and have enjoyed remarkable success on non-Euclidean data, including graph and point clouds. However, the high-level geometric correlations between the input and its neighboring coordinates or features are not fully exploited, resulting in suboptimal segmentation performance. In this article, we propose a novel graph convolution architecture, which we term as Taylor Gaussian mixture model (GMM) network (TGNet), to efficiently learn expressive and compositional local geometric features from point clouds. The TGNet is composed of basic geometric units, TGConv, that conduct local convolution on irregular point sets and are parametrized by a family of filters. Specifically, these filters are defined as the products of the local point features and the neighboring geometric features extracted from local coordinates. These geometric features are expressed by Gaussian weighted Taylor kernels. Then, a parametric pooling layer aggregates TGConv features to generate new feature vectors for each point. TGNet employs TGConv on multiscale neighborhoods to extract coarse-to-fine semantic deep features while improving its scale invariance. Additionally, a conditional random field (CRF) is adopted within the output layer to further improve the segmentation results. Using three point cloud data sets, qualitative and quantitative experimental results demonstrate that the proposed method achieves 62.2% average accuracy on ScanNet, 57.8% and 68.17% mean intersection over union (mIoU) on Stanford Large-Scale 3D Indoor Spaces (S3DIS) and Paris-Lille-3D data sets, respectively.
Mean field theory and Monte Carlo simulation of phase transitions and magnetic properties of a tridimensional Fe7S8 compound

The structural, electronic and magnetic properties of Fe7S8 material have been studied within the framework of the ab initio calculations, the mean field approximation (MFA) and Monte Carlo simulation (MCS). Our study shows that two forms of the iron atoms, Fe2+ with spin S = 2, and Fe3+ with spin σ = 5/2 are the most probable configurations. A mixed Ising model with ferromagnetic spin coupling between Fe2+ and Fe3+ ions and between Fe3+ and Fe3+ ions, and with antiferromagnetic spin coupling between Fe2+ ions of adjacent layers has been used to study the magnetic properties of this compound. We demonstrated that the magnetic phase transition can be either of the first or of the second order, depending on the value of the exchange interaction and crystal field. The presence of vacancies in every second iron layer leads to incomplete cancellation of magnetic moments, hence to the emergence of the ferrimagnetism. Anomalies in the magnetization behavior have been found and compared with the experimental results.

Prevalence of Plasmodium falciparum and Haemoglobin Genotype Distribution among Malaria Patients in Zaria, Kaduna State, Nigeria

Background and Aim: Malaria remains a disease of public health concern in Nigeria and other parts of Africa. It has caused the death of millions of people; especially pregnant women and children in sub-Saharan Africa. This study was aimed at determining the prevalence of Plasmodium falciparum and haemoglobin genotype distribution among malaria patients in Zaria, Kaduna State, Nigeria. Methods: A cross sectional study was carried out in which 300 consenting participants were enrolled; blood samples were collected from them and screened for Plasmodium falciparum using Rapid Diagnostic Test (RDT) and microscopy for confirmation. Bio-data and other relevant information were obtained using structured questionnaire and analyzed statistically. The haemoglobin (Hb) genotypes of all the malaria positive patients were determined. Results: A total prevalence of 21.7% was obtained in this study. Malaria prevalence was higher (29.1%) in participants who were not using insecticides at home compared to those who were using Original Research Article Benjamin et al.; SAJP, 3(2): 1-7, 2019; Article no.SAJP. 53209 2 insecticide at home (17.4%). The P value was significant and the odds ratio showed a significant positive association (p=0.018, OR=0.512, CI=0.294-0.894). Participants with HbAA genotype had the highest percentage of malaria 76.9% (50/65), followed by those with HbAS 18.5% (12/65), HbAC 3.1% (2/65) and HbSS 1.5% (1/65) having the least. Conclusion: Apparently, the use of insecticides to kill mosquitoes around the home helps to reduce malaria prevalence. The haemoglobin genotypes HbAS, HbAC and HbSS may be protective against the development of malaria, as their percentages in this study were relatively low compared to HbAA.
The behavior of Brazilian companies shares return under social responsibility

Several scientific studies seek to establish a relationship between the adoption of corporate social responsibility practices and financial and/or economic performance of companies. There are no definitive answers to this question. Compared performance of ISE – Índice de Sustentabilidade Empresarial (Index of Corporate Sustainability) and Ibovespa index, both from Brazilian stock market, is often used to characterize the influence of good business practices in this area. This work investigated this question in an innovative prism. Instead of using directly that index returns series, we constructed a portfolio composed only of companies that remained in ISE portfolio over the five years from 2012 to 2016, and compared their performance with a portfolio of an equal number of companies, taken among the most liquid ones that continuously participated in the Ibovespa portfolio in same period. For this purpose, we used Mann-Whitney averages comparison test, return series stationarity tests – Augumented Dickey-Fuller and Phillips-Perron - and Engle-Granger cointegration test. The results showed higher average returns for portfolio of socially responsible companies, indicating a growth of their returns compared to portfolio of conventional companies, and showed, however, a tendency to balance in long term run.
Training needs on aquaculture value addition among fish farmers in Borgu Local Government Area, Niger State, Nigeria

The study assessed the training needs of fish farmers on value addition in Borgu Local Government Area, Niger State, Nigeria. Data were collected from fish farmers using interview guide. Descriptive statistics was used to describe the data while Chi-square and Pearson’s Product Moment Correlation were employed to test relationship between variables. Respondents in this study were male dominated, in their productive ages (mean age of 38) and largely well educated (52% had tertiary education). Important training needs of respondents on value addition were improved smoking technology ( x = 2.61), as well as improved packaging and labeling ( x = 2.30), improved short duration storage technology ( x = 2.29) and catching techniques ( x = 2.20). Farmers’ stocking rate (r = 0.266, P = 0.017) and number of ponds (r = 0.243, P = 0.030) had a significant relationship with the training needs of farmers on fish value addition. The study therefore recommended that robust training programme and advisory services be made available by extension for fish farmers in areas of fish smoking, types packaging and storage material in order to enhance their utilization of value addition initiatives in fish farming. Keywords: Fish farming, value addition initiatives, constraints
Managing Water Quality in Premise Plumbing: Subject Matter Experts’ Perspectives and a Systematic Review of Guidance Documents

Although many guidance documents have been developed to inform the design and operation of building water systems to ensure safe water quality, there is a lack of consensus on some topics. This study interviewed 22 subject matter experts (SMEs) to identify topics of concern for managing water quality in buildings and compared SME views with information available on these topics in 15 systematically screened important guidance documents. The study found 18 design and 11 operational topics as critical for managing water quality in buildings. No one guidance document addressed all these topics, suggesting that a compendium of available guidance is needed. SMEs most frequently recommended temperature and residual disinfectant measurements as good parameters for monitoring overall building water quality. Both SME and guidance document recommendations for temperature for controlling opportunistic pathogen growth were reasonably consistent with water heater setpoint >60 °C. However, hot water temperature recommendations varied between 50 and 55 °C for other locations (i.e., the water temperature at the tap or end of the return loop). On the contrary, recommendations for disinfectant residual levels (0.2–2.0 mg/L), flushing frequency (1–14 days), and allowable time for hot water to reach the tap (10–60 s) were not consistent. While this study was able to reconcile diverging views on some of the water quality topics, such as identifying common guidance for water heater set point to at least 60 °C, it also highlights lack of definitive guidance on other critical topics, such as residual level, flushing frequency, hot water time to tap, and the use of thermostatic mixing valves, indicating that these are significant knowledge gaps that need further investigation. The study concludes that there is a need for developing evidence-based guidance, particularly on the topics where expert opinions diverged.
Kudo’s Classification for Colon Polyps Assessment Using a Deep Learning Approach

Colorectal cancer (CRC) is the second leading cause of cancer death in the world. This disease could begin as a non-cancerous polyp in the colon, when not treated in a timely manner, these polyps could induce cancer, and in turn, death. We propose a deep learning model for classifying colon polyps based on the Kudo’s classification schema, using basic colonoscopy equipment. We train a deep convolutional model with a private dataset from the University of Deusto with and without using a VGG model as a feature extractor, and compared the results. We obtained 83% of accuracy and 83% of F1-score after fine tuning our model with the VGG filter. These results show that deep learning algorithms are useful to develop computer-aided tools for early CRC detection, and suggest combining it with a polyp segmentation model for its use by specialists.
Caution in comparing keloid treatment regimens through linear quadratic model

An important dose-comparative study of highdose rate Iridium-192 (Ir-192) brachytherapy for the treatment of keloid surgical scars was published recently by Ahmad et al. Specifically, the treatment outcomes for four different dose regimens from a single centre were compared with other dose regimens reported in the literature and concluded that 10Gy in single fraction seems the optimal treatment. The comparative analyses were based on the biological effective dose (BEDα/β) using the linear quadratic (LQ) model and, throughout the study, α/β=10Gy was used for the quantitative comparison. Indeed, the LQmodel is capable to predict and compare the dose response in the range of 2–18Gy/ fraction, provided appropriate parameters are used. This important issue needs more emphases for the common readers, which we would like to elaborate.
Effect of Corporate Governance Mechanisms on Financial Performance and Firm Value with Green Accounting Disclosure as Moderating Variables

This study aims to examine and analyze the effect of corporate governance mechanisms on financial performance and firm value with the green accounting disclosure as a moderating variable. The study was conducted at the hospitality sub-sector companies listed on the Indonesia Stock Exchange for the period of 2013-2017. Sampling is done by purposive sampling. The analytical methods used are path analysis and moderated regression analysis (MRA). The results of the research in the direct effect test show that corporate governance mechanisms that are proxy by foreign ownership and institutional ownership do not affect the financial performance and firm value. The frequency of audit committee meetings has a significant effect to financial performance and firm value. Financial performance has a significant effect to firm value. The financial performance can not mediate foreign ownership and institutional ownership to firm value. Financial performance can mediate the frequency of audit committee meetings to firm value. Green accounting disclosures have been proven to moderate (weaken) financial performance to firm value. Keywords: corporate governance mechanisms; financial performance, firm value, green accounting disclosure DOI : 10.7176/RJFA/10-24-16 Publication date: December 31 st 2019
The Impact of Work–Family Issues on Turnover Intentions among Nurses? A Study from North-eastern India

The aim of this article is to identify the effects of work–family interface on turnover intentions (TIs) for nurses in public and private hospitals in the Assam region of India. Thus, this study intends to examine the impact of work–family enrichment (WFE) and conflict on TIs among nursing staff. One structured questionnaire was administered to nurses of public and private hospitals located in Guwahati, Barpeta, Dhemaji, Lakhimpur, Tezpur, Jorhat, Dibrugarh, Tinsukia, Duliajan and Silchar regions of Assam, India Republic. The data were analysed using Statistical Package for Social Sciences version 23. Results indicated significant positive relationship between work–family conflict (WFC) and TIs of nurses. On the other hand, findings revealed that WFE also influences TIs but negatively. Thus, both proposed hypotheses were accepted. Implications, contributions and limitations are discussed. Recommendations are made for future work directions.
Pig interorgan balance studies in health and disease

This dissertation describes a clinically relevant pig model that provides insight into metabolic changes in severe sepsis and acute hepatic failure. By using new tracer methods, we demonstrate that intestinal and hepatic interorgan metabolism is very complex and dynamic, even under healthy circumstances. It is shown that in severe sepsis, intestinal and hepatic metabolism is more disturbed than muscle metabolism. This information can contribute to the development of new nutritional strategies in illness. In addition, the protein quality of foods is shown to determine the availability of nutrients in the blood circulation. Therefore, the packaging of food products should always contain information about the protein quality.
A new standard area diagram set for assessment of severity of soybean rust improves accuracy of estimates and optimizes resource use

Soybean rust (SBR), caused by Phakopsora pachyrhizi, is the most important yield- damaging fungal disease of soybean due to severe reduction in healthy leaf area and acceleration of leaf fall. In experimental research, SBR severity is estimated visually aided/trained by a standard area diagram (SAD) developed and validated during the mid- 2000s (Old SAD). In this study, we propose a new SAD set for SBR with six true-colour diagrams following linear increments (c.15% increments) amended with four additional diagrams at low (<10%) severities, totaling 10 diagrams (0.2%, 1%, 3%, 5%, 10%, 25%, 40%, 55%, 70%, and 84%). For evaluation, 37 raters were split into two groups. Each assessed severity in a 50-image sample (0.25% to 84%), first unaided and then using either the Old SAD or the New SAD. Accuracy, precision, and reliability of estimates improved significantly relative to unaided estimates only when aided by the New SAD (accuracy >0.95). Low precision (<0.78) and a trend of underestimation with an increase in severity were the main issues with the Old SAD, which did not differ from unaided estimates. Simulation to evaluate the impact of the errors by different methods on hypothesis tests, showed that the new SAD was more powerful for detecting the smallest difference in mean control (e.g., 70% vs. 65% disease reduction) than the Old SAD; the latter required a 2-fold increase in sample size to achieve the same power. There is a need to improve some SADs, taking advantage of new knowledge and technology to increase accuracy of the estimates, and to optimize both resource use efficiency and management decisions.
Is it OK to ask? The impact of instructor openness to questions on student help-seeking and academic outcomes

Instructors’ actions in the classroom matter; what the instructor does and says can impact students’ attitudes about the course and learning approaches, which can in turn impact the quality of their learning. This study examines the relationships among instructor openness to student questions, student help-seeking behavior, and student final grade in lecture-style college/university courses. Two hundred sixty-eight university students completed measures on their perception of instructor openness to questions and their approach to help-seeking in class. Perceived instructor openness and help-seeking were positively related to grade. Help-seeking mediated the relationship between perceived instructor openness to questions and final grade. Participants were also asked for examples of communication behaviors instructors used to either promote or suppress help-seeking; themes emerging from these responses are presented, and implications for instructors are given.
The Effect of Life Skills Training on Functioning in Schizophrenia: A Randomized Controlled Trial.

OBJECTIVE Psychosocial approaches including occupational therapeutic interventions constitute an important part of mental health treatments. This research was planned to investigate the effects of individualized life skills training on the functionality of individuals diagnosed with schizophrenia. METHOD A total of 32 individuals diagnosed with schizophrenia were assigned randomly to the study (n=15) and the control groups (n=17). The participants were evaluated with the Positive and Negative Syndrome Scale for symptom severity, the Clinical Global Impression Scale for illness severity and improvement and response to treatment, the Katz Index of Independence in Activities of Daily Living and the Lawton - Brody Instrumental Activities of Daily Living Scale for adequacy of performance of basic activities and tasks of daily living, the Functioning Assessment Short Test and Social Functioning Scale for assessing the level of functionality before and after the scheduled interventions for both groups. The control group received a singlesession awareness training to increase independence in daily living activities and the study group received individualized life skills training in 2 sessions per week for 8 weeks (=16 sessions). RESULTS At the end of the research program, improvements were observed in the negative symptoms, general psychopathology, severity of illness and independence in basic and instrumental activities of daily living and functioning in the study group as compared to the control group. CONCLUSION On the basis of the obtained results, we believe that the individualized life skills training may be an effective therapeutic method for the rehabilitation of individuals diagnosed with schizophrenia. The results of our study should be supported by long-term follow-up studies.
