Taschenbuch. Condition: Neu. Neuware - We present the results of a large-area survey for millisecond pulsars (MSPs) at moderately high galactic latitudes with the 64 m Parkes radio telescope, along with follow-up timing and optical studies of the newly-discovered pulsars and several others. Major results include the first precis…e measurement of the mass of a fully recycled pulsar and.

Taschenbuch. Condition: Neu. Neuware - The style of leadership in an interdisciplinary collaboration is an existing gap in collaborative literature. Studying the leaders in an existing interdisciplinary collaboration provided a description of the leadership style of the collaborative leaders of three behavioral health teams in N…ew York City. This qualitative phenomenological study used structured interviews of interdisciplinary disciplines to describe the leadership style of the collaborative leaders within a team environment. The data collection and analysis were conducted using codes to identify dominant themes. The themes presented perceptions and experiences of three teams interacting collaboratively. The coding process identified five major themes that are unique components of leadership that suggests new methods of building collaborative leadership within the interdisciplinary team dynamics.

Taschenbuch. Condition: Neu. Neuware - This study examines suicide perceptions of police officers from two groups, east coast officers and west coast officers. To investigate this problem, the researcher conducted a quantitative analysis utilizing a previously validated instrument. Participants of this study voluntarily complete…d the Suicide Attitude Questionnaire (SUIATT), administered by the National Police Suicide Foundation. The participants consisted of 75 sworn officers from each group varying in age, education, experience, and job description. This study also examined various leadership styles and makes recommendations for leaders to improve upon or implement police suicide prevention training. Risks factors and warning signs were identified by participating officers, which may assist supervisors in identifying potential officers at risk.

Taschenbuch. Condition: Neu. Neuware - The problem of automatic toponym resolution, or computing the mapping from occurrences of names for places as found in a text to an unambiguous spatial footprint of the location referred to, such as a geographic latitude/longitude centroid is difficult to automate due to insufficient and er…ror-prone geographic databases, and a large degree of place name ambiguity: common words need to be distinguished from proper names (geo/non-geo ambiguity), and the mapping between names and locations is ambiguous (London can refer to the capital of the UK or to London, Ontario, Canada, or to about forty other Londons on earth).This thesis investigates how referentially ambiguous spatial named entities can be grounded, or resolved, with respect to an extensional coordinate model robustly on open-domain news text by collecting a repertoire of linguistic heuristics and extra-linguistic knowledge sources such as population. I then investigate how to combine these sources of evidence to obtain a superior method. Noise effects introduced by the named entity tagging that toponym resolution relies on are also studied. While few attempts have been made to solve toponym resolution, these were either not evaluated, or evaluation was done by manual inspection of system output instead of creating a re-usable reference corpus. A systematic comparison leads to an inventory of heuristics and other sources of evidence. In order to carry out a comparative evaluation procedure, an evaluation resource is required, so a reference gazetteer and an associated novel reference corpus with human-labelled referent annotation were created for this thesis, to be used to benchmark a selection of the reconstructed algorithms and a novel re-combination of the heuristics catalogued in the inventory. Performance of the same resolution algorithms is compared under different conditions, namely applying it to the output of human named entity annotation and automatic annotation using an existing Maximum Entropy sequence tagging model.
