Introduction of solids and formula to breastfed infants: a longitudinal prospective study in Uppsala, Sweden

ACTA PAEDIATRICA, Issue 5 2001
A Hörnell
The introduction of solids and formula was studied among 506 breastfed infants in Uppsala, Sweden, based on daily recordings during the first year. The mothers had previously breastfed at least 1 infant for at least 4 mo. Thirty-four per cent of the infants were introduced to solids before the age of 4 mo (4,6 mo is recommended in Sweden). Accustoming the infants to solids was a lengthy process. Life-table analyses showed a median duration of 28 d from the first introduction of solids to consumption of >10 ml daily, and 46 d before the infants ate 100 ml of solids in 1 d for the first time. These durations were longer the younger the infant was at the introduction of solids. Thirty-two per cent of infants given formula consumed 100 ml the first time it was given, and 49% did so within 1 wk, regardless of infant age. Conclusion: Parents and healthcare personnel need to be aware that accustoming breastfed infants to solid food is a lengthy process, and that there is a strong age effect on this duration. It is also important to consider what consequences the (usually) more abrupt introduction of formula might have on breastfeeding. [source]


Seamount science scales undersea mountains: new research and outlook

MARINE ECOLOGY, Issue 2010
Thomas A. Schlacher
Abstract Conventional wisdom suggests that seamounts harbour high levels of biodiversity and endemism, play important roles in marine biogeography, are hotspots of biological carbon processing, and support substantial fisheries. However, since fewer than 300 seamounts have been thoroughly sampled, these generalizations remain largely untested. This has provided the motivation for a number of seamount-focused research projects in recent years, including CenSeam, a field project within the Census of Marine Life. This issue presents some of the research output facilitated by CenSeam. Here we summarize the main findings and provide a précis of future research directions highlighted by contributors to the issue. Recent studies show that seamounts can have comparable levels of benthic diversity and endemism to continental margins, but their communities also include a distinct composition of species that can attain higher biomass. Reported geographic differentiation among seamount communities suggests limited larval dispersal, local speciation, geographic isolation, or a combination of these processes. Genetic studies contained in the issue address these themes explicitly, documenting complex patterns of connectivity that depend on spatial scale and life history characteristics. Globally, seamount ecosystems are also under pressure from bottom-contact fishing and ocean acidification. Contributions detailing the footprint of trawling and a risk assessment confirm what has long been suspected: seamount ecosystems are highly vulnerable to disturbance by bottom trawling and recovery from fishing impacts is a lengthy process, likely requiring decades at a minimum. A predicted shallowing of the aragonite saturation horizon caused by ocean acidification is predicted to place deep-water corals at risk, but seamounts may yet provide a spatial/chemical refuge from these impacts. The issue concludes with a ,myth-buster' synthesis that updates the status of the various seamount ecological paradigms. [source]


Demographic Data on the Victims of the September 11, 2001 Terror Attack on the World Trade Center, New York City

POPULATION AND DEVELOPMENT REVIEW, Issue 3 2002
Article first published online: 27 JAN 200
The magnitude of the death toll resulting from the attack on the World Trade Center is without precedent in the history of terrorist acts. Because of the scale and destructiveness of the buildings' collapse, a final list of the victims required a lengthy process, more so than was the case at the other sites of terrorist violence on the same day,at the Pentagon, Virginia (193 killed, 68 of these on American Airlines Flight 77), and near Shanksville, Pennsylvania (45 killed in the crash of United Airlines Flight 93). After the passing of a year, the list of the victims in New York, while essentially complete, is still not officially closed. On August 19, 2002, the city's medical examiner's office issued a list containing 2,819 names. Reproduced below are some data, released by the city's office of vital statistics, on the demographic characteristics of 2,723 victims (59 of these on United Airlines Flight 175 and 89 on American Airlines Flight 11) for whom a death certificate had been issued,an exacting procedure,as of August 16,2002. The cause of death, in each instance, was entered as homicide. The age distribution reflects the character of the World Trade Center,a workplace,and the time of day,early for tourist visits. The youngest victims perished as passengers in the two airplanes flown into the twin towers. [source]


Ways of seeing environmental change: Participatory research engagement in Yunnan, China, with ethnic minority Hani participants

ASIA PACIFIC VIEWPOINT, Issue 2 2010
John McKinnon
Abstract In this article, I reflect on a participatory learning and action (PLA) and participatory geographic information system (PGIS) project undertaken in two adjacent Hani villages in southern Yunnan, China. After a lengthy process to gain research authorisations, Hani villagers worked with a group of visiting researchers (Hani, Han Chinese and New Zealanders) to articulate local visions of land-use change and environmental challenges. PLA exercises produced a diverse range of hand-made and PGIS products over a 10-week period. As villagers became more accustomed to the ,outsider team', methods , both designed and spontaneous , diversified. Afterwards, based on the results and acting on their own initiative, local leaders backed by popular support moved quickly to reassert traditional and ritually prescribed Hani conservation measures. Nevertheless, these endogenously driven solutions were not necessarily universally beneficial. In describing the complexities encountered in implementing a participatory framework and the ambiguities of the outcomes engendered, I argue that privileging local coherence and celebrating such participatory approaches should not be done at the expense of ignoring the intricacies of on-going contradictory behaviours in a rapidly changing arena. Yet, in China, where authorities often remain suspicious of those seeking to undertake long-term fieldwork, especially among ethnic minorities, PLA offers a potential route forward. [source]
