The paper reports research findings from a field study on accidental ICT help-seeking behaviors in Huifeng West Village and Tuhe Village of Jinghai County,*** employing field observation and in-depth interviews,the relations between local residents’ access to and usage of ICT and their social capital are described:seniors tend to rely on bonding social capital when confronting with difficulties in using mobile devices and computers;the middle-aged always make use of bridging and bonding social capital to shoot ICT troubles and prefer to bridging;children and young adults generally ask for help from friends,or after-sales services in their bridging social capital.

This study investigates the status of digital divide amongst Jordanian Telecentres. The objective of this study is to analyze the impact of the perceived usefulness, the perceived ease-of-use and the facilitating conditions on the behavioral intention of employees. In addition, the study investigates the effect of the three mentioned factors on the user acceptance while the behavioral intention on the user acceptance is used as a mediating factor. The proposed research model was validated by distributing 150 survey questionnaires to the Telecentres in Jordan. Structural equation modeling (SEM) technique was used to analyze the results. One of the main limitations of this study is that the results cannot be universal since the study was limited to Jordan. Similar study needs to be conducted in different courtiers to either support or negate our results.

Topographic map evidence from the Wyoming Wind River-Sweetwater River drainage divide area is used to test a recently proposed regional geomorphology paradigm defined by massive south- and southeast-oriented continental ice sheet melt water floods that flowed across the entire Missouri River drainage basin. The new paradigm forces recognition of an ice sheet created and occupied deep “hole” and is fundamentally different from the commonly accepted paradigm in which a pre-glacial north- and northeast-oriented slope would have prevented continental ice sheet melt water from reaching or crossing the Wind River-Sweetwater River drainage divide. divide crossings (or low points) are identified as places where water once flowed across the drainage divide. Map evidence is interpreted first from the accepted paradigm perspective and second from the new paradigm perspective to determine the simplest explanation. Both paradigm perspectives suggest south-oriented water crossed the drainage divide, although accepted paradigm interpretations do not satisfactorily explain the large number of observed divide crossings and are complicated by the need to bury the Owl Creek and Bridger Mountains to explain why the Wind River now flows in a north direction through Wind River Canyon. New paradigm interpretations explain the large number of divide crossings as diverging and converging channel evidence (as in flood-formed anastomosing channel complexes), Owl Creek and Bridger Mountain uplift to have occurred as south-oriented floodwaters carved Wind River Canyon, and a major flood flow reversal (caused by ice sheet related crustal warping and the opening up of deep “hole” space by ice sheet melting) as being responsible for the Wind River abrupt turn to the north. While this test only addresses topographic map evidence, Occam’s Razor suggests the new paradigm offers what in science should be the preferred Wind River-Sweetwater River drainage divide origin interpretations.

Barbed tributaries flowing in southeast directions, an asymmetric drainage divide with both the South Fork Grand River and the North Fork Moreau River, and the Jump-off escarpment-surrounded basin (interpreted here to be a large abandoned headcut) are examples of topographic map evidence suggesting the north oriented Little Missouri River valley eroded headward across a large southeast oriented anastomosing complex of ice-marginal melt water flood flow channels that once crossed Harding County, South Dakota. Additional evidence includes southeast oriented tributaries to the northeast oriented South Fork Grand River and multiple divide crossings (e.g. through valleys and wind gaps) on the Boxelder Creek-Little Missouri River divide (in eastern Montana and west of the Little Missouri River) and suggests deep regional erosion occurred as the north oriented Little Missouri River valley eroded headward into and across the region. Harding County is located south and west of the southwest limit of coarse-grained glacial erratic material and ice-marginal melt water flow routes logically should have crossed it. Deep melt water erosion of Harding County and adjacent eastern Montana regions to the west is not consistent with many previous drainage history and glacial history interpretations, but is consistent with deep erosion by continental ice sheets.

Academic-practitioner divides in disaster management and research can be persistent and pernicious,bearing consequences for disaster survivors and future affected populations. The gap between disaster professionals and academic researchers is often treated as an unavoidable structural problem or a neutral accident of professional silos and circumstance. We suggest that these gaps are not neutral, and that they can and must be overcome. With hundreds of millions of people affected by disaster each year and recovery costs skyrocketing, there is urgency in connecting researcher and practitioner knowledges to avoid expensive mistakes and most importantly, to decrease human suffering. Yet the difficulties that US academic anthropologists and practitioners experienced in their efforts to collaborate became evident in a cross-sector National Science Foundation(NSF)-funded workshop on the relevance of culture in disaster work. We suggest and illustrate how more systematic cross-field communication can be operationalized through engaging in an ongoing and relational process of bridging. Such a process can offer long-term benefits to the people and institutions involved,dramatically enhance the science of disaster management,and help reduce the social and material costs of disaster impacts.

This article gives a computing method to calculate the geostrophic current. The fact that kinetic energy of geostrophic motion and geostrophic potential energy reach minimum simultaneously, Fomin’s "principle of minimum kinetic energy" is equivalent to the principle of minimum geostrophic potential energy . We concluded that horizontal geostrophic velocities at different depths are along the same direction . Combining our method with C. Wunsch’s inverse method we can obtain the velocity components along and normal to the hydrographic sections . We used and analysed CTD and current meter data of " Experiment No . 3 " exploration, December 1985-January 1986, in the west Pacific Ocean - Philippine area.

Starfish oocytes with intact germinal vesicles (GVs) were cut along desired planes with glass needles or ligated using silk thread loops into two parts and allowed to mature in vitro, and inseminated. The experimental results showed that (1) only the parts with GVs or partial GV contents (PGVCs) cleaved, those without any GV materials did not; but nucleated and non-nucleated fragments cut from mature eggs were able to divide; (2) the development of animal parts of oocytes containing GVs or PGVGs was like that of animal fragments of matured oocytes with female pronuclei; most of them gave rise to permanent blastulae. and just a few formed ectodermal vesicles with a little primary mesenchyme; (3) a large part of vegetal fragments with GVs or PGVCs. and the vegetal parts of mature eggs without female pronuclei developed into small but normal embryos; (4) the fragments containing GVs or PGVCs obtained from the oocytes along a plane parallel to the animal-vegetal (A-V) axis developed as normally as the

From the viewpoint of system approach, karst drainage basin is the ideel unit in studying structure and evolutional regularity of karst hydrogeomorpholegical system, It is because the drainage basin is a natural unit with clear border which can reflect the internal structure and outside environment of the system and their interrelation. Through the research on karst hydrology and geomorphology, four basic characteristics of the karst drainage basin have been identified.
