Polio eradication efforts in regions of geopolitical strife: the Boko Haram threat to efforts in sub-Saharan Africa.

The World Health Organization aims to eradicate wild poliovirus worldwide by the end of 2018. Cameroon and Nigeria, neighboring countries, have been affected by the terrorist and militant activities of the Islamist sect Boko Haram. Impacted regions are mainly the far North of Cameroon and Northern Nigeria. Targets of Boko Haram aggression in these zones include violence against polio workers, disruption of polio immunization campaigns, with consequent reduced access to health care and immunization. In addition to this significant problem, Northern Nigeria has historically seen rejection of polio virus vaccine initiatives. It remains to know how health systems can continue operations against polio in areas where Boko Haram operates. If appropriate measures are not urgently taken, it will be not possible to meet the 2018 goal of polio virus eradication. The response should include specialized immunization activities in conflict zones, will engagement of leaders. Countries should also explore immunization activities by soldiers and military personnel.

Zika is not a reason for missing the Olympic Games in Rio de Janeiro: response to the open letter of Dr Attaran and colleagues to Dr Margaret Chan, Director - General, WHO, on the Zika threat to the Olympic and Paralympic Games

Attaran and colleagues in an open letter to WHO expressed their concern about the upcoming Olympic and Paralympic Games in Rio de Janeiro and the threat posed by the Zika epidemic (Attaran 2016). We agree that Zika virus is of great public health concern and much remains to be known about this disease. Care should be taken to reduce the risk of infection, especially to pregnant women. However, we argue that this is not sufficient reason for changing the original plans for the Games, in particular because of the time of the year when they will take place. The present article outlines several scientific results related to Zika and mosquito-borne infectious diseases dynamics that we believe ratify the current position of WHO in not endorsing the postponing or relocation of the 2016 Olympic and Paralympic Games (WHO 2016).

Tribes under threat : the collective behavior of firms during the stock market crisis

Due to their unpredictable behavior, stock markets are examples of complex systems. Yet, the dominant analysis of these markets as- sumes simple stochastic variations, eventually tainted by short-lived memory. This paper proposes an alternative strategy, based on a stochastic geometry defining a robust index of the structural dynamics of the markets and based on notions of topology defining a new coef- ficient that identifies the structural changes occurring on the S&P500 set of stocks. The results demonstrate the consistency of the random hypothesis as applied to normal periods but they also show its in- adequacy as to the analysis of periods of turbulence, for which the emergence of collective behavior of sectoral clusters of firms is mea- sured. This behavior is identified as a meta-routine.

Do hatchery-reared sea urchins pose a threat to genetic diversity in wild populations?

In salmonids, the release of hatchery-reared fish has been shown to cause irreversible genetic impacts on wild populations. However, although responsible practices for producing and releasing genetically diverse, hatchery-reared juveniles have been published widely, they are rarely implemented. Here, we investigated genetic differences between wild and early-generation hatchery-reared populations of the purple sea urchin Paracentrotus lividus (a commercially important species in Europe) to assess whether hatcheries were able to maintain natural levels of genetic diversity. To test the hypothesis that hatchery rearing would cause bottleneck effects (that is, a substantial reduction in genetic diversity and differentiation from wild populations), we compared the levels and patterns of genetic variation between two hatcheries and four nearby wild populations, using samples from both Spain and Ireland. We found that hatchery-reared populations were less diverse and had diverged significantly from the wild populations, with a very small effective population size and a high degree of relatedness between individuals. These results raise a number of concerns about the genetic impacts of their release into wild populations, particularly when such a degree of differentiation can occur in a single generation of hatchery rearing. Consequently, we suggest that caution should be taken when using hatchery-reared individuals to augment fisheries, even for marine species with high dispersal capacity, and we provide some recommendations to improve hatchery rearing and release practices. Our results further highlight the need to consider the genetic risks of releasing hatchery-reared juveniles into the wild during the establishment of restocking, stock enhancement and sea ranching programs.

Prevalence of chronic diseases in private healthcare sector of South Africa: A threat to public health

Purpose: To evaluate the prevalence of patients suffering from registered chronic disease list (CDL) conditions in a section of the South African private health sector from 2008 - 2012. Methods: This study was a retrospective analysis of the medicine claims database of a nationally (South African) representative Pharmacy Benefit Management (PBM) company data between 2008 and 2012. Statistical analysis was used to analyse the data. Descriptive analysis was performed to calculate the prevalence of CDL conditions for the entire population, and stratified by age and gender. However, MIXED linear modelling was used to determine changes in the average number of CDL conditions per patient, adjusted for age and gender from 2008 - 2012. Results: An increase of 0.20 in chronic diseases was observed from 2008 - 2012 in patients having any CDL condition, with an average of 1.57 (1.57 - 1.58, 95 % CI) co-morbid CDL conditions in 2008 and 1.77 (1.77 - 1.78, 95 % CI) in 2012. This increase in average number of CDL conditions per patient between 2008 and 2012 was statistically significant (p < 0.05), but with no large practical significance (d < 0.8). Conclusion: Prevalence of patients with CDL conditions along with risk of co-morbidity has been increasing with time in the private health sector of South Africa. Risk of increased co-morbidity with age and among different genders was prevalent.

Constructing Threat: How Americans Identify Economic Competitors

China’s emergence as an economic powerhouse has often been portrayed as threatening to America’s economic strength and to its very identity as “the global hegemon.” The media’s alarmist response to an economic competitor is familiar to those who remember US-Japanese relations in the 1980s. In order to better understand the basis of American threat perception, this study explores the independent and interactive impact of three variables (perceptions of the Other’s capabilities, perceptions of the Other as a threat versus as an opportunity, and perceptions of the Other’s political culture) on attitudes toward two different economic competitors (Japan 1977-1995 and China 1985-2011). Utilizing four methods (historical process tracing, public polling data analysis, social scientific experimentation, and content analysis), this study demonstrates that increases in the Other’s economic capabilities have a much smaller impact on attitudes than is commonly believed. It further shows that while perceptions of threat/opportunity played a significant role in shaping attitudinal response toward Japan, perceptions of political culture are the most important factor driving attitudes toward China today. This study contributes to a better understanding of how states react to threats and construct negative images of their economic rivals. It also helps to explain the current Sino-American relationship and enables better predictions as to its potential future course. Finally, these findings contribute to cultural explanations of the democratic peace phenomenon and provide a boundary condition (political culture) for the liberal proposition that opportunity ameliorates conflict in the economic realm.

The practices of existential psychotherapists: Development and application of an observational grid

Within the major therapeutic paradigms, observational instruments have been developed to assess orientation-specific interventions or processes. However, to date, no such instrument exists to assess existential practices. Recent research indicates the key practices of existential therapists, and forms an empirical basis on which to develop an observatory grid. This paper describes the development of such a grid, and its exploratory testing with eight clients of four Portuguese existential psychotherapists. A total of 32 sessions were observed and both speaking turn and whole-session analysis showed that it was feasible to assess existential therapy using the instrument, although psychometric findings recommend further refinement of the tool. Session-rating data suggest that the chief practices applied by existential therapists were relational, followed by the use of hermeneutic interventions and reformulations. Interventions based on phenomenological and existential assumptions were observable in practice but limited in frequency. Further refinements and developments of the observational grid, together with additional research – using a range of therapists from different schools of existential therapy – are recommended.

The Role of Existential Beliefs Within the Relation of Centenarians’ Health and Well-Being

The purpose of this study was to explore the role of existential beliefs in mediating the influence of health on centenarians' well-being. A total of 80 centenarians (mean age 101.1; SD = 1.3; 81.3 % women) with no/minor cognitive impairment were included. The OARS questionnaire for diseases and functional capacity (ADL, IADL), the Satisfaction with Life Scale, and the existential beliefs subscale were used for data collection. The findings suggest that existential resources are a crucial element for mitigating the impact of health constraints in subjective well-being in this population. Appropriate models of intervention for very old age that recognize the importance of religion, spirituality, and meaning of life are to be considered.

Review of Two Issues at the Long-Term Commitment Facilities, Department of Juvenile Justice: 1)Safety Threat to Employees & Juveniles; and 2)Event Reporting Process Integrity Allegations

The Legislative Oversight Committee of the South Carolina House of Representatives, referred allegations pertaining to the Department of Juvenile Justice (DJJ) which were generated during its ongoing oversight study of DJJ. Specifically, the safety issues focused on lack of control; lack of trust; and lack of adequate staffing. This review’s scope and objectives were: Investigate specific complainant allegations of DJJ employees underreporting, misreporting, or destroying ERs; Review the efficiency and effectiveness of DJJ’s event reporting process and follow-up on anomalies or potential patterns of systemic underreporting, misreporting, or missing ERs; and Assess juvenile and employee safety conditions through interviewing a cross-section of relevant employees, record review, and possibly an employee survey.

Vihara architecture: defining the existential foothold of VIII century Buddhist monastery "Somapura Mahavihara" of ancien Bengal

Lost in history, the ruin of ‘Somapura Mahavihara’ was not recognized separated from its birthplace, i.e. nature, for more than 700 years. Yet, within its silent presence, the monument dominated the name of the region: ‘Paharpur’ (land of hillock), according to its appearance surrounds by its flat land topo¬graphy. Discovered in 1919, the single largest Buddhist Vihara (monas¬tery) of ancient Bengal came into light, pronouncing the flou¬rishing minute of Buddhist architecture, once dominant religious force of the subcontinent. The earliest historical monumental architecture of greater Asia, had long been deriving itself from the Buddhist monastic architecture as early as VI century BC. In line of history, the discovery of ‘Somapura Mahavihara’ contributed attesting the sensitivities of a highly sophisticated architectonic typology of Vihara Architecture in the land of ancient Bengal. The recovery of ‘Somapura Mahavihara’ was not only from its cradle of nature, but also from its remarkable existence imprinted in the reign of Pala dynasty (750 - 1155 AD) announcing the existential foothold of man in his nature. The existential foothold of ‘Somapura Mahavihara’ comprises the factors, responsible in shaping the anchorage of the mo¬nument since the birth of Vihara architecture, as early as 530 BC. These factors not only denote the building technology in response to its environment but also the amalgamation of be¬lief, upon which the dwellers transformed the site as a place announcing their existence on earth. This research paper aims at exploring the existential foothold of ‘Somapura Mahavihara’, in terms of its territorial, functional, structural, social, cultural, religious sym¬bolic hierarchies of human achievement while clarifying the architectonic typology that shaped ‘Somapura Mahavihara’ through evolution process of ‘Vihara Architecture’. This understanding intends to combine the archaeological knowledge with comparative architectural analysis of contem¬porary Viharas of ancient Bengal, to define the singularity of ‘Somapura Mahavihara’. In consequence, the glorious past of ‘Somapura Mahavihara’ is intended to portray through iden¬tifying the relation of religious and functional rationalism with the connotation of art, architecture and belief moulded within natural forces, as one complete entity; RESUMO: Vihara Arquitetura: Definindo a posição existencial do século VIII Budista mosteiro “Somapura Mahavihara” de Bengala antiga. Perdidas na História, as ruínas de ‘Somapura Mahavihara’ foram confundidas com uma montanha durante mais de setecentos anos. Contudo, no seu silêncio presente, o monumento marcou a toponímia da região; ‘Paharpur’ significa ‘a terra do outeiro’, evidenciando a singularidade deste monumento numa região dominada por uma extensa planície. Em 1919, foi descoberto o maior mosteiro budista da antiga região de Bengal, demonstrando a prosperidade da arquitectura budista. Tem¬poralmente, a descoberta de ‘Somapura Mahavihara’ contribuiu para atestar a evolução e a sofisticação da tipologia arquitectónica denominada ‘Arquitectura Vihara’, existente na antiga região de Bengal. A noção de pegada existencial de ‘Somapura Mahavihara’ compreende os factores responsáveis por moldar a ancoragem do monumento ao lugar em que se insere desde o início da arquitectura Vihara, que remonta a 530 a.C. Estes factores evidenciam a tecnologia construtiva empregue para responder ao ambiente envolvente mas também a evolução da religião, factores estes que os monges construtores consideraram ao transformar o lugar e anunciar a sua existência na Terra. Esta investigação tem por objectivo explorar a noção de pegada existencial de ‘Somapura Mahavihara’, nas suas dimensões territoriais, funcionais, estruturais, sociais, culturais e nas hierarquias simbólicas das realizações humanas para clarificar a tipologia arquitectónica que deu forma a ‘Somapura Mahavihara’ durante a evolução da arquitectura Vihara. Este entendimento pretende combinar/cruzar o conhecimen¬to arqueológico com estudos arquitectónicos comparativos de Viharas na antiga região de Bengal, com o objectivo de definir a singularidade de ‘Somapura Mahavihara’. Neste estudo estudar-se-á também o confronto entre a dimensão religiosa e a artística (divino vs. humano), integrados na arquitectura de ‘Somapura Mahavihara’ em perfeita harmonia.

Exploring nest destruction and bird mortality in mown Mediterranean dry grasslands: an increasing threat to grassland bird conservation

In recent years, haying has extended to Iberian Mediterranean dry grasslands potentially impacting on grassland bird ecology. We evaluated the impact of haying on a grassland bird community of South Portugal. Our main goals were: (1) to investigate the exposure of different species to haying, (2) to investigate potential removal of nests and dead birds from hayed fields by haying machinery using the ratio (REC) between the expected number of records and the number of records collected and (3) to link clutch destruction and bird mortality with haying management practices. Hayed fields were surveyed for signs of breeding and birds censused prior to mowing. Linear models were computed, linking the REC with haying machinery and sward properties. GLMs and model averaging were used to obtain models linking clutch destruction, bird mortality and haying management variables. Only 4 % of records evidenced successful nesting attempts (N = 177). REC evaluation suggested high nest or dead bird removal by the machinery, particularly in fields with lower vegetation biomass prior to cutting. Sickle bar mowers and one-rotor rotary rakes returned higher REC but lower probability of found nests removed from the original nesting sites comparatively to discs mowers and wheel rakes. Higher probabilities of mortality events were found in fields mown earlier (but not in all years). On the other hand, lower mortality was found in fields raked with two-rotor rotary rakes. Delayed haying, silage production in temporary crops and the use haying machinery enabling simultaneously mowing and gathering hay in lines are discussed as management alternatives.

La paradoja de Maastricht. Los distintos modelos económicos y políticos para el futuro integrador de la UE

La crisis existencial del proyecto de integración europea constituye el principal reto al que debe enfrentarse la Comunidad en su futuro más inmediato puesto que se alza como toda una amenaza para la continuidad del sistema establecido desde el Tratado fundacional de Roma (1957). Las tres crisis acontecidas durante los primeros años del siglo XXI, véase la gran crisis económica del año 2008, la pandemia global de la Covid-19 y la actual intervención de la Federación Rusa en Ucrania, están poniendo constantemente a prueba la firmeza de los cimientos y valores sobre los cuales se ha construido la Comunidad durante todos estos años. Esta tesis doctoral pretende ser una contribución académica al debate abierto en las sociedades comunitarias acerca de por donde debe de transitar la evolución del proyecto de integración europea en los próximos años. Para conseguir alcanzar este objetivo, la investigación se retrotrae hasta los orígenes del proceso de integración y avanza en la línea temporal hasta nuestros días, analizando con ello las posibles causas que pudieran encontrarse detrás de la crisis existencial actual. A su vez, , la investigación estudia con detenimiento los múltiples efectos que está generando la problemática existencial en los Estados miembros en los últimos años, tales como el aumento del apoyo social a favor de actores considerados populistas o el fenómeno de la creciente desafección ciudadana. Esta investigación analiza los distintos escenarios propuestos por la Comisión Europea en su Libro Blanco sobre el futuro de Europa para determinar cuál podría ser el mejor escenario que concordara con la nueva realidad económica y sociopolítica que actualmente impera en los Estados miembro. Lo que se persigue es formular una propuesta que pueda dar por terminada la crisis existencial de la Comunidad abriendo con ello una nueva etapa en la historia de la integración europea.

Un framework per la gestione di moduli di insider threat detection basati su eBPF

Gli Insider Threat sono una problematica complessa e rappresentano una delle problematiche più costose per le organizzazioni: questi ultimi possono, potenzialmente, realizzare grandi guadagni dalle informazioni sottratte danneggiando i clienti e provocando danni irreparabili all’organizzazione. Screening effettuati prima dell’assunzione e la costruzione di un relazione di fiducia basata sulla collaborazione rimangono fondamentali ma, spesso, non sono sufficienti ed è bene integrare il processo di difesa da insider threat all’interno delle business operation. Date queste precondizioni, l’obiettivo di questa tesi è stato quello di cercare un approccio sistematico per affrontare il problema dell’Insider Threat e di fornire nuovi strumenti per la sua detection altamente specializzati nel campo della cyber-security. Dato il campo applicativo, risulta fondamentale rendere questo processo totalmente trasparente al potenziale insider threat. Le più moderne tecniche di hiding, prese dai moderni malware, sono state implementate utilizzando eBPF rendendo possibile unire una quasi totale invisibilità unita alla stabilità garantita da questa tecnologia.

Threat Hunting: analisi e sperimentazione di metodologie di ricerca di vulnerabilità

La caccia alle minacce è una tecnica in cui si ”cercano” fisicamente i ”rischi”, possibili o esistenti, all’interno dell’infrastruttura IT. La caccia alle minacce è un processo proattivo e iterativo guidato da esseri umani che cercano attività ostili, sospette o dannose che sono sfuggite al rilevamento mediante le attuali tecniche automatizzate attraverso reti, endpoint o set di dati come i file di registro. Un caso possibile può essere quello in cui un threat hunter abbia a disposizione per la caccia solo i registri di log provenienti da fonti diverse e anche da diversi sistemi operativi. Questi file di log potrebbero per esempio essere i dati di 3 giorni di raccolta provenienti da 30 40 macchine Windows o Linux e analizzando solamente essi il cacciatore deve essere in grado di determinare se e quali siano le minacce all’interno di una o più macchine del sistema. Un problema che sorge subito all’occhio è come si possa conciliare dati provenienti da fonti differenti, e soprattutto da sistemi operativi diversi; inoltre, un ulteriore problema può essere il determinare quando un file di log sia effettivamente un segnalatore di una minaccia e non un falso positivo. Di conseguenza è richiesta una visibilità totale della rete, nonché dei dati dei dispositivi. Idealmente, sarebbe necessario uno strumento che consenta di avere una panoramica di tutti questi dati con funzionalità di ricerca in grado di contestualizzare ciò che si vede per ridurre al minimo la quantità di ricerca manuale attraverso i registri non elaborati. In questo elaborato verranno mostrate le attività. di simulazione sia su ambiente Linux che ambiente Windows, in cui si andranno a cercare, attraverso gli strumenti che verranno elencati nei primi capitoli, le varie minacce. Verranno quindi simulati degli scenari di attacchi e ne si farà infine un’analisi su come al meglio rilevarli.

Cyber threat intelligence: identifying hardcoded secrets in GitHub

The usage of version control systems and the capabilities of storing the source code in public platforms such as GitHub increased the number of passwords, API Keys and tokens that can be found and used causing a massive security issue for people and companies. In this project, SAP's secret scanner Credential Digger is presented. How it can scan repositories to detect hardcoded secrets and how it manages to filter out the false positives between them. Moreover, how I have implemented the Credential Digger's pre-commit hook. A performance comparison between three different implementations of the hook based on how it interacts with the Machine Learning model is presented. This project also includes how it is possible to use already detected credentials to decrease the number false positive by leveraging the similarity between leaks by using the Bucket System.
