An interpretative phenomenological analysis of the lived experience of suicidal behaviour

Background: In Scotland, suicide prevention is a major public health challenge, with two people, on average, dying every day due to suicide. Any efforts to prevent suicide should be aided by research. Existing research on suicide is dominated by quantitative research that has largely focused on providing explanatory accounts of suicidal phenomena. Research providing rich and detailed accounts of suicidal behaviour among individuals who have directly experienced it is growing but remains relatively embryonic. This study sought to supplement existing understanding of attempted suicide specifically by exploring the processes, meaning and context of suicidal experiences among individuals with a history of attempted suicide. Methods: The study used a retrospective qualitative design with semi-structured in-depth interviews. Participants were patients (n=7) from a community mental health service in Glasgow, Scotland who had attempted suicide within the previous 12-month period. The interviews were transcribed verbatim and were analysed for recurrent themes using interpretative phenomenological analysis (IPA). Results: Three super-ordinate themes, each with inter-related sub-themes, emerged from the analysis. 1) “Intentions”: This theme explored different motives for suicide, including providing relief from upsetting feelings; a way of establishing control; and a means of communicating with others. 2) “The Suicidal Journey”: This theme explored how individuals’ thinking can change when they are suicidal, including feeling overwhelmed by a build-up of distress and a narrowing of their perspective. 3) “Suicidal Dissonance”: This theme explored how people can feel conflicted about suicide and can be fearful of the consequences of their suicidal behaviour. Conclusion: Participants’ accounts were dominated by experience of significant adversity and psychological suffering. These accounts provided valuable insights into the suicidal process, highlighting implications for clinical practice and future research.

Human resources management, citizenship behavior, and turnover intention in the portuguese public administration

Framed by a social exchange perspective, this study address the issue of whether positive employees’ perceptions about human resource management practices influence positive attitudes and behaviour. We hypothesize that human resource management practices (HRMP) have a significant negative effect on intention to voluntary leave the organization and a positive effect on organizational citizenship behaviour (OCB), and that OCB could mediate the relationship between HRMP and turnover intention. A sample of 165 employees from the Portuguese public administration participated in the study. Data was analysed through descriptive statistics, confirmatory factor analysis and hypotheses were tested using single and multiple linear regressions. Results indicate that HRMP is positively associated with OCB, but only internal communication practice is highly valued by Portuguese public employees and successfully predicts OCB. HRMP also show a positive association with turnover intention but only celebration and recognition practices are predictors of turnover intention. Contrary to our hypothesis OCB did not acted as mediator between HRMP and turnover intention. Some suggestions on managerial human resource practices were proposed as well as some main questions raised in the Portuguese public administration context.

Crossing frontiers between tourism and demography. An empirical analysis based on European travellers’ behaviour

This paper aims to establish possible tourism demand scenarios of European travellers to Portugal based on the relationship with changing population structures. A combination of the EuROBAROMETER report 370 (“Attitudes of Europeans towards Tourism in 2013”) and the cohort-component method for population projections will allow the development of different possible tourism demand scenarios. Following the European report, individuals who travelled in 2013 were most likely to live in a household with two or more individuals. Thus, if elderly couples are together till later in their life and in better physiological shape, it is possible that the number of elderly individuals travelling for tourism purposes will increase in the near future. If we can expect tourists from developing countries to be younger due to their demographic dynamics than those from developed countries, where the ageing population is growing fast, we can expect that the percentage of the elderly among tourists will increase. Furthermore, the 2013 European report found that the combination of socio-demographic variables, such as, age, population, gender, household dimension, country of residence and trip purpose explained tourism demand scenarios for Portugal, confirming that seniors and families evidence a paramount sense of importance for the destination. In the literature there is a lack of discussion about the effects of demography in the future and the role of an ageing population in tourism demand choice patterns. We aim to contribute to filling this gap. Consequently, we strongly believe that this paper contributes to the literature by introducing a new field of discussion about the importance of demographic changes in shaping travel trends.

Multifactorial analysis and food safety issues of edible marine gastropods intended for human consumption

The present thesis aims to evaluate a method to assess the viability; estimate the bacterial and viral (Hepatitis A and Norovirus) contamination; describe how some parameters change during a week in refrigerated condition and after 24 hours of immersion; estimate indole-producing bacteria and biogenic amines; evaluate the presence of saxitoxin and tetrodotoxin. The method to assess the viability using sea salt is easy to apply. Marine gastropods did not accumulate fecal contaminants, but vibrios due to their feeding. The Vibrio spp. load was even higher than the one registered on Ruditapes philippinarum belonging to the same area For what to concern the evaluation during a week in refrigerated condition and after 24 hours of immersion, non-re-immersed gastropods exceeded the acceptable mortality (10%) after three days in refrigerated conditions, but the Vibrio spp. load did not show a significant increase within three days. The TVC was already high from the beginning and its major part consisted of SSOs, which could be explained by gastropods’ feed, such as the Pseudomonas spp. load and the abundance of IPB. The BAs amount was also correlated with viability and had a statistically significant difference within a week on refrigerated conditions, principally because putrescine, tyramine, spermidine, and cadaverine rise in non-re-immersed samples. It also should be noted that the BAs amount was higher on average than the recommendation of literature. Moreover, re-immersed batches showed acceptable viability even after 3 days, and the Vibrio spp. load, TVC, SSOs, and biogenic amines remained almost constant within a week contrary to non-re-immersed samples. Finally, T. mutabilis and B. brandaris did not accumulate NoVs and TTX. We obtained only one positivity of the HAV sample and traces of STX (not at levels toxic to humans). Our results contribute to identifying food-borne hazards for T. mutabilis and B. brandaris.

Evaluation of the microstructural pattern and mechanical behaviour of human metastatic vertebrae

La spina dorsale è uno dei principali siti di sviluppo di metastasi ossee. Queste alterano sia la composizione strutturale che il comportamento meccanico delle vertebre metastatiche, riducendone la resistenza meccanica ed aumentandone il rischio di rottura. Questo studio ha valutato la composizione microstrutturale ed il comportamento meccanico a rottura in specifiche regioni all’interno di vertebre metastatiche. 11 segmenti vertebrali da cadavere, costituiti da una vertebra sana ed una con metastasi (litica, mista o blastica), sono stati testati con carichi graduali di compressione e scansionati con microCT. Le deformazioni interne sono state misurate tramite un algoritmo globale di Digital Volume Correlation (DVC). I risultati dall’analisi microstrutturale hanno mostrato l’ influenza sulla microstruttura delle diverse tipologie di metastasi in corrispondenza della lesione, mentre le caratteristiche microstrutturali nelle regioni intorno alla lesione sono risultate simili a quelle delle vertebre sane. L’analisi delle deformazioni ha inoltre permesso di valutare l’ effetto delle diverse tipologie di metastasi nel compromettere la stabilità spinale. Le vertebre con metastasi litiche hanno raggiunto deformazioni maggiori in corrispondenza della lesione, regione meccanicamente più debole e con una microstruttura maggiormente compromessa a causa della metastasi. Le vertebre con metastasi blastiche hanno raggiunto deformazioni minori nella lesione, regione che ha mostrato una maggiore resistenza meccanica ai carichi, e deformazioni maggiori nelle zone più lontane. Le vertebre con metastasi miste hanno mostrato un comportamento meccanico non univoco, legato alla predominanza di una lesione sull’altra. Infatti, la posizione e la proporzione tra le due lesioni sembra influenzare il comportamento meccanico. I risultati di questo studio, una volta generalizzati, potrebbero portare alla spiegazione delle cause di instabilità meccanica nelle vertebre metastatiche.

Analysis of human posterior EEG alpha frequency as a function of implicit learning of probabilistic lateralized stimuli in a visual detection task

Alpha oscillatory activity has long been associated with perceptual and cognitive processes related to attention control. The aim of this study is to explore the task-dependent role of alpha frequency in a lateralized visuo-spatial detection task. Specifically, the thesis focuses on consolidating the scientific literature's knowledge about the role of alpha frequency in perceptual accuracy, and deepening the understanding of what determines trial-by-trial fluctuations of alpha parameters and how these fluctuations influence overall task performance. The hypotheses, confirmed empirically, were that different implicit strategies are put in place based on the task context, in order to maximize performance with optimal resource distribution (namely alpha frequency, associated positively with performance): “Lateralization” of the attentive resources towards one hemifield should be associated with higher alpha frequency difference between contralateral and ipsilateral hemisphere; “Distribution” of the attentive resources across hemifields should be associated with lower alpha frequency difference between hemispheres; These strategies, used by the participants according to their brain capabilities, have proven themselves adaptive or maladaptive depending on the different tasks to which they have been set: "Distribution" of the attentive resources seemed to be the best strategy when the distribution probability between hemifields was balanced: i.e. the neutral condition task. "Lateralization" of the attentive resources seemed to be more effective when the distribution probability between hemifields was biased towards one hemifield: i.e., the biased condition task.

Neural Machine Translation in the Field of Law. Analysis and Evaluation against Human Reference of NMT Raw Outputs of an Atto Costitutivo of S.r.l. from Italian into German.

Artificial Intelligence (AI) is gaining ever more ground in every sphere of human life, to the point that it is now even used to pass sentences in courts. The use of AI in the field of Law is however deemed quite controversial, as it could provide more objectivity yet entail an abuse of power as well, given that bias in algorithms behind AI may cause lack of accuracy. As a product of AI, machine translation is being increasingly used in the field of Law too in order to translate laws, judgements, contracts, etc. between different languages and different legal systems. In the legal setting of Company Law, accuracy of the content and suitability of terminology play a crucial role within a translation task, as any addition or omission of content or mistranslation of terms could entail legal consequences for companies. The purpose of the present study is to first assess which neural machine translation system between DeepL and ModernMT produces a more suitable translation from Italian into German of the atto costitutivo of an Italian s.r.l. in terms of accuracy of the content and correctness of terminology, and then to assess which translation proves to be closer to a human reference translation. In order to achieve the above-mentioned aims, two human and automatic evaluations are carried out based on the MQM taxonomy and the BLEU metric. Results of both evaluations show an overall better performance delivered by ModernMT in terms of content accuracy, suitability of terminology, and closeness to a human translation. As emerged from the MQM-based evaluation, its accuracy and terminology errors account for just 8.43% (as opposed to DeepL’s 9.22%), while it obtains an overall BLEU score of 29.14 (against DeepL’s 27.02). The overall performances however show that machines still face barriers in overcoming semantic complexity, tackling polysemy, and choosing domain-specific terminology, which suggests that the discrepancy with human translation may still be remarkable.

Prognostic Value Of Dna And Mrna E6/e7 Of Human Papillomavirus In The Evolution Of Cervical Intraepithelial Neoplasia Grade 2.

This study aimed at evaluating whether human papillomavirus (HPV) groups and E6/E7 mRNA of HPV 16, 18, 31, 33, and 45 are prognostic of cervical intraepithelial neoplasia (CIN) 2 outcome in women with a cervical smear showing a low-grade squamous intraepithelial lesion (LSIL). This cohort study included women with biopsy-confirmed CIN 2 who were followed up for 12 months, with cervical smear and colposcopy performed every three months. Women with a negative or low-risk HPV status showed 100% CIN 2 regression. The CIN 2 regression rates at the 12-month follow-up were 69.4% for women with alpha-9 HPV versus 91.7% for other HPV species or HPV-negative status (P < 0.05). For women with HPV 16, the CIN 2 regression rate at the 12-month follow-up was 61.4% versus 89.5% for other HPV types or HPV-negative status (P < 0.05). The CIN 2 regression rate was 68.3% for women who tested positive for HPV E6/E7 mRNA versus 82.0% for the negative results, but this difference was not statistically significant. The expectant management for women with biopsy-confirmed CIN 2 and previous cytological tests showing LSIL exhibited a very high rate of spontaneous regression. HPV 16 is associated with a higher CIN 2 progression rate than other HPV infections. HPV E6/E7 mRNA is not a prognostic marker of the CIN 2 clinical outcome, although this analysis cannot be considered conclusive. Given the small sample size, this study could be considered a pilot for future larger studies on the role of predictive markers of CIN 2 evolution.

Integrated Proteomics Identified Up-regulated Focal Adhesion-mediated Proteins In Human Squamous Cell Carcinoma In An Orthotopic Murine Model.

Understanding the molecular mechanisms of oral carcinogenesis will yield important advances in diagnostics, prognostics, effective treatment, and outcome of oral cancer. Hence, in this study we have investigated the proteomic and peptidomic profiles by combining an orthotopic murine model of oral squamous cell carcinoma (OSCC), mass spectrometry-based proteomics and biological network analysis. Our results indicated the up-regulation of proteins involved in actin cytoskeleton organization and cell-cell junction assembly events and their expression was validated in human OSCC tissues. In addition, the functional relevance of talin-1 in OSCC adhesion, migration and invasion was demonstrated. Taken together, this study identified specific processes deregulated in oral cancer and provided novel refined OSCC-targeting molecules.

Lawsonia Inermis-mediated Synthesis Of Silver Nanoparticles: Activity Against Human Pathogenic Fungi And Bacteria With Special Reference To Formulation Of An Antimicrobial Nanogel.

Lawsonia inermis mediated synthesis of silver nanoparticles (Ag-NPs) and its efficacy against Candida albicans, Microsporum canis, Propioniabacterium acne and Trichophyton mentagrophytes is reported. A two-step mechanism has been proposed for bioreduction and formation of an intermediate complex leading to the synthesis of capped nanoparticles was developed. In addition, antimicrobial gel for M. canis and T. mentagrophytes was also formulated. Ag-NPs were synthesized by challenging the leaft extract of L. inermis with 1 mM AgNO₃. The Ag-NPs were characterized by Ultraviolet-Visible (UV-Vis) spectrophotometer and Fourier transform infrared spectroscopy (FTIR). Transmission electron microscopy (TEM), nanoparticle tracking and analysis sytem (NTA) and zeta potential was measured to detect the size of Ag-NPs. The antimicrobial activity of Ag-NPs was evaluated by disc diffusion method against the test organisms. Thus these Ag-NPs may prove as a better candidate drug due to their biogenic nature. Moreover, Ag-NPs may be an answer to the drug-resistant microorganisms.
