Public health education specialists and nurses often work interprofessionally in the public health setting. Using a mixed-methods design, this exploratory study evaluated the effect of an online interprofessional case study activity on nursing and public health education students' perceptions of each other's professional role. For the public health experimental group only, a statistically significant change (p < .05) was found in their perceptions of the professional roles of nurses including large changes in six specific domains. Recommendations for implementing interprofessional education programs include more emphasis on education about professional scopes of practice and roles/responsibilities of the health professions.

We examine the social burden associated with resilience to environmental shocks in pre-modern societies. We argue that analyses of state-level interventions to mitigate the consequences of catastrophic events tend to isolate these measures from their larger social contexts and thereby overlook the uneven distribution of their burden across different groups. We use three cases of pre-modern societies in the northeastern Mediterranean - the sixth century Roman Empire, the tenth century Byzantine Empire, and the sixteenth century Ottoman Empire. We demonstrate how the adaptive processes that reinforced resilience at the state level incurred different burdens for those at lower levels of the social hierarchy. We found that some groups sustained losses while others gained unexpected benefits in the context of temporary systemic instability. We also found that although elites enjoyed enhanced buffers against the adverse effects in comparison with non-elites, this did not consistently guarantee them a better outcome. We conclude that the differentiated burden of resilience could in some cases entrench existing political or economic configurations, and in other cases, overturn them. Our case studies indirectly address the pressing issue of environmental justice.

This article analyses high-quality hydroclimate proxy records and spatial reconstructions from the Central and Eastern Mediterranean and compares them with two Earth System Model simulations (CCSM4, MPI-ESM-P) for the Crusader period in the Levant (1095-1290 CE), the Mamluk regime in Transjordan (1260-1516 CE) and the Ottoman crisis and Celâlî Rebellion (1580-1610 CE). During the three time intervals, environmental and climatic stress tested the resilience of complex societies. We find that the multidecadal precipitation and drought variations in the Central and Eastern Mediterranean cannot be explained by external forcings (solar variations, tropical volcanism); rather they were driven by internal climate dynamics. Our research emphasises the challenges, opportunities and limitations of linking proxy records, palaeoreconstructions and model simulations to better understand how climate can affect human history.

OBJECTIVE: The purpose of this article is to present a case study of the evolution of postgraduate-level training programs for alcohol and other drug (AOD) practitioners provided by two universities in New Zealand. METHOD: The case study compiles details on relevant treatment contexts and systems in New Zealand and key milestones and significant developments in postgraduate AOD practitioner programs in two locations over a 30-year period. The details were compiled by the authors, all of whom were closely involved with the development of the training programs. RESULTS: The key ingredients for success that were identified included a focus on specialized learning overlaying generic undergraduate professional training; a core commitment to practice oriented teaching; investment in the training by government bodies; and the parallel emergence of professional bodies, registration systems, and collaborative relationships across agencies. In a small country, the two programs have enabled 345 students to obtain specialist postgraduate qualifications in AOD practice over a 10-year period. CONCLUSIONS: Little could have been achieved without ongoing cooperation between education providers, government agencies, and AOD services. This history may be of interest to those in other locations attempting to establish nation- or statewide approaches to AOD practitioner training.

In the early exploration and colonization of the Americas, Europeans encountered unfamiliar climates that challenged received ideas from classical geography. This experience drove innovative efforts to understand and explain patterns of weather and seasons in the New World. A close examination of three climatic puzzles (the habitability of the tropics, debates on the likelihood of a Northwest Passage, and the unexpectedly harsh weather in the first North American colonies) illustrates how sixteenth- and seventeenth-century observers made three intellectual breakthroughs: conceiving of climates as a distinct subject of inquiry, crossing the hitherto-separated disciplines of geography and meteorology, and developing new theories regarding the influence of prevailing winds on patterns of weather and seasons. While unquantified and unsystematic, these novel approaches promoted a new understanding of climates critical to the emergence of climate science. This study offers new insights into the foundations of climatology and the role of the New World in early modern science.

Titania nanostructures are of increasing interest for a variety of applications, including photovoltaics, water splitting, and chemical sensing. Because of the photocatalytical properties of TiO2, chemical processes that occur at its surface can be exploited for highly efficient nanodevices. A facile and fast synthesis route has been explored that is free of catalysts or templates. An environmental scanning electron microscopy (ESEM) system was employed to grow titania nanowires (NWs) in a water vapor atmosphere (∼1 mbar) and to monitor the growth in situ. In addition, the growth process was also demonstrated using a simple vacuum chamber. In both processes, a titanium filament was heated via the Joule effect and NWs were found to grow on its surface, as a result of thermal oxidation processes. A variety of nanostructures were observed across the filament, with morphologies changing with the wire temperature from the center to the end points. The longest NWs were obtained for temperatures between ∼730 °C and 810 °C. Typically, they have an approximate thickness of ∼300 nm and lengths of up to a few micrometers. Cross sections prepared by focused-ion-beam milling revealed the presence of a porous layer beneath the NW clusters. This indicates that the growth of NWs is driven by oxidation-induced stresses in the subsurface region of the Ti filament and by enhanced diffusion along grain boundaries. To demonstrate the potential of titania NWs grown via the hot filament method, single NW devices were fabricated and used for conductometric sensing of hydrogen sulfide (H2S) gas. The NW electric resistance was found to decrease in the presence of H2S. Its variation can be explained in terms of the surface depletion model.
