National cybersecurity strategies:review and analysis of evaluation frameworks

Abstract. National cybersecurity strategies (NCSS) are becoming increasingly important for society. They provide essential support for the development of both digital and traditional infrastructure, and a well-designed strategy can have a tremendous positive impact on a country. Therefore, for developers of a new strategy or researchers of previously published ones, it is good to understand the current state of the art on evaluating national cybersecurity strategy documents. Unfortunately, while there is some research on these strategies and comparisons between them, the published work is superficial. Moreover, the publications do not disclose their research methods, so it is challenging to evaluate their results. These limitations make it difficult to rely on previous research. Objectives and proposed activities to achieve the desired outcomes form an essential part of a national cybersecurity strategy. However, little research on them exists. The relevant NCSS guides focus on structuring the entire drafting process at a high level, without details or suggestions on subtopics such as typical objectives or activities. This thesis addresses the research question: How are activities and objectives defined in the evaluation frameworks, and how do they relate to each other? In particular, can they be analyzed in a replicable way so that a body of knowledge of common and valuable objectives and activities in NCSS could be built? It turns out that the existing definitions for objectives are lax. There is no consensus between NCSS writers or researchers in this domain on defining an objective or activity. As a result, these are readily mixed in the source documents, and the analytical frameworks that were studied are not extracting them reliably from the source documents. The constructive analysis is one way of consistently defining the objectives and activities and applying a practical inference method to discover the connections between them. This approach was tested with the source material available from the previous works. By applying the method in this research, objectives, and activities were classified more rigorously. The classification work enabled a better understanding of the activities and further analysis of their relationships, which were then documented and organized into a graph representation. That graph of objectives and activities can help readers and developers of future strategies to think about how to organize the goals of their NCSS. Furthermore, this research could provide a way for systematically expanding the body of knowledge about the requirements and dependencies, thus making it more straightforward to include objectives and activities in future strategies. Finally, several future research avenues are discussed, which would expand the knowledge about the NCSS documents and begin to track their evolution more robustly over time. For example, there are avenues for both manual analysis and machine-learning-based unsupervised learning methods that could be applied for further insights

Jurassic shift from abiotic to biotic control on marine ecological success

Environmental change and biotic interactions both govern the evolution of the biosphere, but the relative importance of these drivers over geological time remains largely unknown. Previous work suggests that, unlike environmental parameters, diversity dynamics differ profoundly between the Palaeozoic and post-Palaeozoic eras. Here we use the fossil record to test the hypothesis that the influence of ocean chemistry and climate on the ecological success of marine calcifiers decreased throughout the Phanerozoic eon. Marine calcifiers build skeletons of calcite or aragonite, and the precipitation of these calcium carbonate polymorphs is governed by the magnesium-to-calcium ratio and temperature in abiotic systems. We developed an environmental forcing model based on secular changes of ocean chemistry and temperature and assessed how well the model predicts the proliferation of skeletal taxa with respect to calcium carbonate polymorphs. Abiotic forcing governs the ecological success of aragonitic calcifiers from the Ordovician to the Middle Jurassic, but not thereafter. This regime shift coincides with the proliferation of calcareous plankton in the mid-Mesozoic. The deposition of biomineralizing plankton on the ocean floor buffers CO2 excursions and stabilizes Earth’s biochemical cycle, and thus mitigates the evolutionary impact of environmental change on the marine biota

Local carboplatin delivery and tissue distribution in livers after radiofrequency ablation

Abstract: This study investigated the local drug pharmacokinetics of intralesional drug delivery after radiofrequency ablation of the liver. We hypothesized that the tissue architecture damaged by the ablation process facilitates the drug penetration in the liver and potentially enlarges the therapeutic margin in the local treatment of cancer. The delivery rate and tissue distribution of carboplatin, an anticancer agent, released from poly(D,L-lactide-co-glycolide) implants into rat livers after radiofrequency ablation were quantified by atomic absorption spectroscopy. Results showed that carboplatin clearance through blood perfusion was significantly slower in the ablated livers, leading to a more extensive tissue retention and distribution of the drug

Invasive thyroglossal duct cyst papillary carcinoma: a case report

<p>Abstract</p> <p>Introduction</p> <p>A thyroglossal duct cyst is the most common congenital anomaly of the thyroid gland and midline masses in childhood (70% abnormality in childhood, 7% in adult). Carcinomas arising from a thyroglossal duct cyst are rare (only 1% of thyroglossal duct cyst cases) and characterized by relatively non-aggressive behavior and rare lymphatic spread. They are also diagnosed mostly during the third and fourth decades of life. About 85% to 92% of all thyroglossal duct cyst carcinomas are papillary carcinomas.</p> <p>Case presentation</p> <p>We present the case of a 44-year-old Iranian woman with Cacausian ethnicity with a painless anterior neck mass that appeared gradually over three months. She had a history of frequent painful swelling of the anterior part of her neck, which subsided with antibiotic therapy. Thyroid functional tests were normal and a thyroid scinitigraphy showed a cold nodule in the left lobe of her thyroid. A computed tomography scan revealed a large, heterogeneous enhancing soft tissue mass with cystic components in the midline of the anterior neck space. This extended from the base of the tongue,(completely separated from its muscles, to the inferior aspect of the thyroid gland and showed the destruction of the hyoid bone and the thyroid cartilage. The diagnosis of a thyroglossal duct cyst with malignant transformation was maintained. A fine needle aspiration revealed papillary carcinoma.</p> <p>Conclusion</p> <p>This patient's case is presented because of its rare, aggressive, and invasive nature and rare and unusual manifestation, as well as its rapid increase in size, the destruction of the hyoid bone, chondrolysis of the thyroid cartilage, lymph adenopathy and the existence of a cold nodule in the thyroid gland.</p

Looking both ways

On the occasion of the 25th anniversary of the journal, Psychotherapy Research, three former editors first look back at: (i) the controversial persistence of the Dodo verdict (i.e., the observation that all bona fide therapies seem equally effective); (ii) the connection between process and outcome; (iii) the move toward methodological pluralism; and (iv) the politicization of the field around evidence-based practice and treatment guidelines. We then look forward to the next 25 years, suggesting that it would be promising to focus on three areas: (i) systematic theory-building research; (ii) renewed attention to fine-grained study of therapist techniques; and (iii) politically expedient research on the outcomes of marginalized or emerging therapies

The terrain of health policy analysis in low and middle income countries: a review of published literature 1994–2007

This article provides the first ever review of literature analysing the health policy processes of low and middle income countries (LMICs). Based on a systematic search of published literature using two leading international databases, the article maps the terrain of work published between 1994 and 2007, in terms of policy topics, lines of inquiry and geographical base, as well as critically evaluating its strengths and weaknesses. The overall objective of the review is to provide a platform for the further development of this field of work

Practice-Driven Evaluation of a Multi-layered Psychosocial Care Package for Children in Areas of Armed Conflict

Psychosocial and mental health service delivery frameworks for children in low-income countries are scarce. This paper presents a practice-driven evaluation of a multi-layered community-based care package in Burundi, Indonesia, Sri Lanka and Sudan, through a set of indicators; (a) perceived treatment gains; (b) treatment satisfaction; (c) therapist burden; (d) access to care; (e) care package costs. Across four settings (n = 29,292 children), beneficiaries reported high levels of client satisfaction and moderate post-treatment problem reductions. Service providers reported significant levels of distress related to service delivery. Cost analyses demonstrated mean cost per service user to vary from 3.46 to 17.32 € depending on country and specification of costs. The results suggest a multi-layered psychosocial care package appears feasible and satisfactory in reaching out to substantial populations of distressed children through different levels of care. Future replication should address therapist burden, cost reductions to increase sustainability and increase evidence for treatment efficacy

Working Inside for Smoking Elimination (Project W.I.S.E.) study design and rationale to prevent return to smoking after release from a smoke free prison

<p>Abstract</p> <p>Background</p> <p>Incarcerated individuals suffer disproportionately from the health effects of tobacco smoking due to the high smoking prevalence in this population. In addition there is an over-representation of ethnic and racial minorities, impoverished individuals, and those with mental health and drug addictions in prisons. Increasingly, prisons across the U.S. are becoming smoke free. However, relapse to smoking is common upon release from prison, approaching 90% within a few weeks. No evidence based treatments currently exist to assist individuals to remain abstinent after a period of prolonged, forced abstinence.</p> <p>Methods/Design</p> <p>This paper describes the design and rationale of a randomized clinical trial to enhance smoking abstinence rates among individuals following release from a tobacco free prison. The intervention is six weekly sessions of motivational interviewing and cognitive behavioral therapy initiated approximately six weeks prior to release from prison. The control group views six time matched videos weekly starting about six weeks prior to release. Assessments take place in-person 3 weeks after release and then for non-smokers every 3 months up to 12 months. Smoking status is confirmed by urine cotinine.</p> <p>Discussion</p> <p>Effective interventions are greatly needed to assist these individuals to remain smoke free and reduce health disparities among this socially and economically challenged group.</p> <p>Trial Registration</p> <p><a href="http://www.trialregister.nl/trialreg/admin/rctview.asp?TC=01122589">NCT01122589</a></p

Tectonic structure, evolution, and the nature of oceanic core complexes and their detachment fault zones (13°20′N and 13°30′N, Mid Atlantic Ridge)

Microbathymetry data, in situ observations, and sampling along the 138200N and 138200N oceanic core complexes (OCCs) reveal mechanisms of detachment fault denudation at the seafloor, links between tectonic extension and mass wasting, and expose the nature of corrugations, ubiquitous at OCCs. In the initial stages of detachment faulting and high-angle fault, scarps show extensive mass wasting that reduces their slope. Flexural rotation further lowers scarp slope, hinders mass wasting, resulting in morphologically complex chaotic terrain between the breakaway and the denuded corrugated surface. Extension and drag along the fault plane uplifts a wedge of hangingwall material (apron). The detachment surface emerges along a continuous moat that sheds rocks and covers it with unconsolidated rubble, while local slumping emplaces rubble ridges overlying corrugations. The detachment fault zone is a set of anostomosed slip planes, elongated in the alongextension direction. Slip planes bind fault rock bodies defining the corrugations observed in microbathymetry and sonar. Fault planes with extension-parallel stria are exposed along corrugation flanks, where the rubble cover is shed. Detachment fault rocks are primarily basalt fault breccia at 138200N OCC, and gabbro and peridotite at 138300N, demonstrating that brittle strain localization in shallow lithosphere form corrugations, regardless of lithologies in the detachment zone. Finally, faulting and volcanism dismember the 138300N OCC, with widespread present and past hydrothermal activity (Semenov fields), while the Irinovskoe hydrothermal field at the 138200N core complex suggests a magmatic source within the footwall. These results confirm the ubiquitous relationship between hydrothermal activity and oceanic detachment formation and evolution
