ABSTRACT Based on modern microbiology, we propose a major revision in current space exploration philosophy and planetary protection policy, especially regarding microorganisms in space. Mainly, microbial introduction should not be considered accidental but inevitable. We hypothesize the near impossibility of exploring new planets without carrying and/or delivering any microbial travelers. In addition, although we highlight the importance of controlling and tracking such contaminations—to explore the existence of extraterrestrial microorganisms—we also believe that we must discuss the role of microbes as primary colonists and assets, rather than serendipitous accidents, for future plans of extraterrestrial colonization. This paradigm shift stems partly from the overwhelming evidence of microorganisms’ diverse roles in sustaining life on Earth, such as symbioses and ecosystem services (decomposition, atmosphere effects, nitrogen fixation, etc.). Therefore, we propose a framework for new discussion based on the scientific implications of future colonization and terraforming: (i) focus on methods to track and avoid accidental delivery of Earth's harmful microorganisms and genes to extraterrestrial areas; (ii) begin a rigorous program to develop and explore ‘Proactive Inoculation Protocols’. We outline a rationale and solicit feedback to drive a public and private research agenda that optimizes diverse organisms for potential space colonization.

The severe shocks that rocked the world economy in the 1970s and the ensuing efforts to adjust and to renew economic growth have had a profound effect on the economic literature. Especially the external and public debt problems which reached critical dimensions in many countries attracted much attention. Thus, in the field of macroeconomics financial issues have gained more prominence over the last two decades. Studies relating to the fiscal deficit have been particularly numerous. The critical size of national public debts, the contribution of the public debt to external debt, the reduced confidence in the state as the guide in socioeconomic development and the role of fiscal policy in adjustment processes are among the main reasons for this increased interest.

Skilled birth attendance and institutional delivery have been advocated for reducing maternal, neonatal mortality and infant mortality (NMR and IMR). This paper examines the role of place of delivery with respect to neo-natal and infant mortality in India using four rounds of the Indian National Family Health Survey conducted in 2015–2016. The place of birth has been categorized as “at home” or “public and private institution.” The role of place of delivery on neo-natal and infant mortality was examined by using multivariate hazard regression models adjusted for clus-tering and relevant maternal, socio-economic, pregnancy and new-born characteristics. There were 141,028 deliveries recorded in public institutions and 54,338 in private institutions. The esti-mated neonatal mortality rate in public and private institutions during this period was 27 and 26 per 1000 live births respectively. The study shows that when the mother delivers child at home, the chances of neonatal mortality risks are higher than the mortality among children born at the health facility centers. Regression analysis also indicates that a professionally qualified provider′s antenatal treatment and assistance greatly decreases the risks of neonatal mortality. The results of the study illustrate the importance of the provision of institutional facilities and proper pregnancy in the prevention of neonatal and infant deaths. To improve the quality of care during and imme-diately after delivery in health facilities, particularly in public hospitals and in rural areas, accel-erated strengthening is required.

Objective: To discuss and reflect upon the role of medical practitioners, including psychiatrists, as health advocates on behalf of patients, carers and staff. Conclusions: Health advocacy is a key professional competency of medical practitioners, and is part of the RANZCP framework for training and continuing professional development. Since advocacy is often a team activity, there is much that is gained experientially from volunteering and working with other more experienced health advocates within structurally and financially independent (of health systems and governments) representative groups (RANZCP, AMA, unions). Doctors may begin with clinically proximate advocacy for improved healthcare in health systems, across the public and private sectors. Health advocacy requires skill and courage, but can ultimately influence systemic outcomes, sway policy decisions, and improve resource allocation.

Abstract Background The intersphincteric plane (ISP) is a potential space between the external and the internal anal sphincters. About 90% of the perianal sepsis is caused by an obstruction of the ducts of anal glands with subsequent secondary bacterial infection. The imaging modalities used to diagnose perianal sepsis are the ultrasound via endoanal and transperineal routes and magnetic resonance imaging. Objective  The study aimed to identify the various patterns of the ISP sepsis and their incidence among our study group and to clarify the significance of ISP in the pathogenesis of anorectal abscesses and various types of perianal fistula tracts, to optimize the surgical management. Methods Retrospective descriptive study in which 57 patients with an ISP sepsis were evaluated with full medical history, clinical exam, and ultrasound; the final diagnosis was based on combining the results of ultrasound, digital rectal examination under anesthesia, and the operative results. Results The current study showed many patterns of the ISP sepsis and estimated the incidence of each pattern among our study group; such patterns could be fistula tracts, sinus tracts, abscesses, intersphincteric abscess with supralevator extension, sinus with abscess formation, fistula with abscess formation, distension of the ISP with free pus, and other complex patterns like horse abscess, abscess with transsphincteric sinus, and ISP fistula/sinus with transsphincteric branches. Conclusion Understanding the role of the ISP in the pathogenesis of anorectal abscesses and perianal fistula tracts can help in reaching the optimum way of management.

The role of town centre management (TCM) schemes in the UK has expanded to incorporate a more overt and explicit focus on marketing and promotion. This paper considers the marketing/promotional activities of TCM schemes in the UK. TCM schemes operate at the interface of the public and private sectors. The implications of this are discussed, including the need for a consensual approach by a wide range of urban stakeholders, and the actual activities undertaken, influenced by the funding imperative under which such schemes operate (which impacts on the feasibility of certain activities and the efforts made to evaluate them). Comparisons are drawn between specific place marketing practice by TCM schemes and wider place marketing strategies.

The nurse is one of the professionals responsible for the care directed toward the physical, mental and social development of newborns in the Neonatal Intensive Care Unit. This study aimed to comprehend the experience of nurses working in a Neonatal Intensive Care Unit. Data collection was performed in 2008, through interviews with 12 nurses working in public and private hospitals of the city of São Paulo. The units of meaning identified were grouped into three categories: Developing actions; Perceiving their actions and Expectations. The analysis was based on social phenomenology. It was concluded that the overload of activities, the reduced number of staff, the lack of materials, equipment and the need for professional improvement are the reality of the work of the nurse in this sector. To supervise the care is the possible; integral care of the newborn, involving the parents, is the ideal desired.

AbstractCentral to policies relating to risk governance at the regional and local levels is the interaction between the public and private sectors also referred to as networked governance. At the same time, the role of political actors in general and policy entrepreneurs in particular, in terms of policy change, has gained considerable traction in recent policy scholarship. The purpose of this study was to investigate the change in governance arrangements resulting in the formation of a coordination network in regional flood risk management-the first of its kind in Sweden. Our research is guided by the following questions: first, would the policy change (the establishment of the networks)have taken place if a policy entrepreneur were not part of the policy transfer process? Second, what is the role of policy entrepreneurship in the implementation of the policy after its nationwide adoption? Third, what other factors played a role in the variation of the results in the implemented policy that is, the enforced networks? We find the role of a policy entrepreneur key in the policy transfer from the regional to the national level. In order to investigate the resultant networks, we draw from B. Guy Peters (1998) and his conceptualization of factors which affect the politics of coordination. In addition to the presence of a policy entrepreneur, we compare: (i) pluriformity of network members;(ii) member interdependence; (iii) redundancy of structures, and (iv) degree of formality (in terms of meetings). Our findings suggest that entrepreneurs contribute to the variation in the functionality of the enforced river groups, though other factors play a significant role as well.Most importantly, perhaps, we did not identify entrepreneurs in any of the river groups which were not functional.
