Statistical analysis of rainfall, river head and piezometric level data of central-Adriatic alluvial aquifers

The statistical and hydrogeological analysis of the relationships between rainfall, river and piezometric level historical data can be useful to characterize the aquifers and to manage the groundwater resources. For this purpose measurements acquired every three days, relative to 1986-2009 period, concerning the Pescara river alluvial plain (Fig.1), were analyzed with several statistical methods. The alluvial bodies of the Pescara river is mainly silty-sandy. The plain aquifer is supported by Plio-Pleistocenic clayey deposits. The three wells (Fig. 2) are located in the medium-low alluvial plain. Autocorrelation and spectral univariate analysis, cross-correlation and bivariate spectral analysis have been implemented with the purpose to evaluate the memory effect, the delay of the piezometric level response to rainfall and river head/discharge impulse, and the periodical components of the time series (Mangin, 1984; Larocque et al., 1998; Polemio and Dragone, 1999)

This research was based on the unsatisfied process in learning mathematics at grade X IIS 1 of SMAN 10 Pekanbaru. It was seen from the low motivation of the students to learn mathematics while the learning process. These problems impact on the number of students who pass the Exponents and Logarithms test with percentage of 2.5%. The research was a Classroom Action Research that aims to improve the learning process and increase the motivation of the students to learn mathematics by implementing Cooperative Learning Approach Structural of Think Pair Square (TPS). There were 40 students in the class consisting 21 boys and 19 girls as the participant of this research. The instruments of data collecting in this research were observation sheets (observation of teacher and students activity and observation of students motivation) and the motivation questionnaire. The observation sheets were analyzed in qualitative descriptive, while the motivation questionnaire were analyzed using the Wilcoxon signed-rank test. The qualitative descriptive showed an improvement of learning process and increased the motivation of students to learn mathematics in the class from before to after the action. The Wilcoxon signed-rank test for all indicators of motivation questionnaire obtained , so that and for each indicator of the motivation to learn mathematics obtained . From this test is rejected, in other words, the motivation to learn mathematics at grade X IIS 1 of SMAN 10 Pekanbaru increased after the action. Based on these results it can be concluded that the application of Cooperative Learning Approach Structural of TPS can improved the learning process and increased motivation to learn mathematics at grade X IIS 1 of SMAN 10 Pekanbaru on first semester of academic year 2014/2015

Hadronic shift in pionic hydrogen

The hadronic shift in pionic hydrogen has been redetermined to be $\epsilon_{1s}=7.086\,\pm\,0.007(stat)\,\pm\,0.006(sys)$\,eV by X-ray spectroscopy of ground state transitions applying various energy calibration schemes. The experiment was performed at the high-intensity low-energy pion beam of the Paul Scherrer Institut by using the cyclotron trap and an ultimate-resolution Bragg spectrometer with bent crystals.Comment: 10 pages, 6 figure

Exploring the aquifers shaping Italy's sub-urban landscape

This review paper examines the hydrogeological characteristics and challenges of urban groundwater management in ten major Italian cities: Torino, Milano, Padova, Bologna, Roma, Pescara, Napoli, Bari, Catania, and Cagliari. Urbanisation has placed significant pressure on groundwater systems, highlighting the need for sustainable management. The study categorises the cities based on their hydrogeological settings and groundwater uses, identifying key issues such as salinisation, industrial contamination, and land subsidence. The findings emphasise the importance of urban local aquifers (ULAs) not only for meeting the demand for both drinking and industrial water but also for providing ecological support. The paper advocates for integrated urban water management and governance to enhance resilience against potential future water shortages and climate change impacts

Sexual abuse and HIV-risk behaviour among black and minority ethnic men who have sex with men in the UK

Black and minority ethnic (BME) men who have sex with men (MSM) face a major burden in relation to HIV infection. It was hypothesised that sexual abuse would predict sexual risk-taking, and that this relationship would be mediated by victimisation and maladaptive coping variables. Four hundred and thirty-two BME MSM completed the survey; 54% reported no sexual abuse and 27% reported sexual abuse. Mann–Whitney tests showed that MSM with a history of sexual abuse reported higher frequency of drug use, and of homophobia and racism than those reporting no prior sexual abuse. A structural equation model showed that the experience of sexual abuse was positively associated with sexual risk-taking and that this relationship was mediated by victimisation variables: frequency of racism and frequency of homophobia and by the maladaptive coping variable: frequency of drug use. The findings can inform the design of psycho-sexual and behavioural interventions for BME MSM

Signal Appropriation of Explicit HIV Status Disclosure Fields in Sex-Social Apps used by Gay and Bisexual Men

HIV status disclosure fields in online sex-social applications ("apps") are designed to help increase awareness, reduce stigma, and promote sexual health. Public disclosure could also help those diagnosed relate to others with similar statuses to feel less isolated. However, in our interview study (n=28) with HIV positive and negative men who have sex with men (MSM), we found some users preferred to keep their status private, especially when disclosure could stigmatise and disadvantage them, or risk revealing their status to someone they knew offline in a different context. How do users manage these tensions between health, stigma, and privacy? We analysed our interview data using signalling theory as a conceptual framework and identify participants developing 'signal appropriation' strategies, helping them manage the disclosure of their HIV status. Additionally, we propose a set of design considerations that explore the use of signals in the design of sensitive disclosure fields

Migration and identity processes among first-generation British South Asians

There has been little scholarly attention to the identities and migratory experiences of first-generation British South Asians, especially from social psychologists. Drawing upon Identity Process Theory, this article examines the inter-relations between migration and identity processes among twenty first-generation British South Asians. The interview data were analysed using qualitative thematic analysis. Results suggested that migration was perceived as a means of enhancing identity and that following migration individuals acquired a ‘higher’ social status in the homeland. Moreover, the psychologically traumatic aspects of migration, such as the loss of community and ‘otherisation’ from one's ethnic ingroup, were outlined. It is argued that migration can have profound socio-psychological implications and that decades later it can continue to shape individuals' sense of self and their attachment to relevant social categories. Furthermore, migration has important outcomes for the extent and nature of British national identification as well one's relationship with the ethnic ‘homeland’

Polarised press reporting about HIV prevention: social representations of pre-exposure prophylaxis in the UK press

Pre-exposure prophylaxis is a novel biomedical HIV prevention option for individuals at high risk of HIV acquisition. Although pre-exposure prophylaxis has yielded encouraging results in various clinical trials, opponents argue that pre-exposure prophylaxis poses a number of risks to human health and to sexually transmitted infection prevention efforts. Using qualitative thematic analysis and social representation theory, this article explores coverage of pre-exposure prophylaxis in the UK print media between 2008 and 2015 in order to chart the emerging social representations of this novel HIV prevention strategy. The analysis revealed two competing social representations of pre-exposure prophylaxis: (1) as a positive development in the ‘battle’ against HIV (the hope representation) and (2) as a medical, social and psychological setback in this battle, particularly for gay/bisexual men (the risk representation). These social representations map onto the themes of pre-exposure prophylaxis as a superlatively positive development; pre-exposure prophylaxis as a weapon in the battle against HIV/AIDS; and risk, uncertainty and fear in relation to pre-exposure prophylaxis. The hope representation focuses on taking (individual and collective) responsibility, while the risk representation focuses on attributing (individual and collective) blame. The implications for policy and practice are discussed

Identity management strategies among HIV-positive Colombian gay men in London

This study set out to explore the social-psychological aspects of living with HIV among a group of HIV-positive Colombian gay men in London, and the strategies that they deployed to manage ensuing threats to their identities. Focus group and individual interview data were collected from 14 Colombian gay men living with HIV, and were analysed using qualitative thematic analysis and identity process theory. The following themes are discussed: (1) identity struggles and conflicts in Colombia, (2), managing multiple layers of social stigma in England, and (3) changing interpersonal and intergroup dynamics, which highlight the inter-connections between sexual prejudice, sexual risk-taking and HIV stigma. Identity may be chronically threatened due to the multiple layers of stigma, which can limit the coping strategies available to individuals. Findings strongly support the need for action and programmes to highlight and tackle both racism and HIV stigma on the gay scene and to fund more specific resources for sub-communities of gay, bisexual and other men who have sex with men, which employ appropriately trained and culturally competent staff
