Automatic routing module

Automatic Routing Module (ARM) is a tool to partially automate Air Launched Cruise Missile (ALCM) routing. For any accessible launch point or target pair, ARM creates flyable routes that, within the fidelity of the models, are optimal in terms of threat avoidance, clobber avoidance, and adherence to vehicle and planning constraints. Although highly algorithmic, ARM is an expert system. Because of the heuristics applied, ARM generated routes closely resemble manually generated routes in routine cases. In more complex cases, ARM's ability to accumulate and assess threat danger in three dimensions and trade that danger off with the probability of ground clobber results in the safest path around or through difficult areas. The tools available prior to ARM did not provide the planner with enough information or present it in such a way that ensured he would select the safest path

Ethical Issues in Empirical Studies of Software Engineering

The popularity of empirical methods in software engineering research is on the rise. Surveys, experiments, metrics, case studies, and field studies are examples of empirical methods used to investigate both software engineering processes and products. The increased application of empirical methods has also brought about an increase in discussions about adapting these methods to the peculiarities of software engineering. In contrast, the ethical issues raised by empirical methods have received little, if any, attention in the software engineering literature. This article is intended to introduce the ethical issues raised by empirical research to the software engineering research community, and to stimulate discussion of how best to deal with these ethical issues. Through a review of the ethical codes of several fields that commonly employ humans and artifacts as research subjects, we have identified major ethical issues relevant to empirical studies of software engineering. These issues are illustrated with real empirical studies of software engineering

North by Northwest : Information literacy at Yukon College and Lakehead University

In Northern communities, isolation is a fact of life and common southern "realities" like high-speed internet, libraries (both public and academic) within driving distance and f2f instruction are not the norm. Due to these factors, online instruction is a core component in northern academic institutions and as such requires a little bit more preparation. As well, another key factor to consider is the diverse student population: First Nations, mature, part-time, first generation university students, and professionals upgrading their credentials. The diverse academic backgrounds of these students makes designing the standard library tutorial a challenge; one size does not fit all in the north. At the same time, this might be the only way that students interact with a librarian so the online environment becomes significant to these students' academic studies (and hopefully success). So how does an academic library with such a variety of students a) reach these students? b) design online tutorials targeting a variety of learning styles? and c) assess whether any of this is working? This session will show you how to take a generic one hour information literacy class and turn it into an online session that will meet the needs of a diverse student population. The presenters will discuss effective pedagogical approaches to online instruction, how to teach specific e-resources and finally how to ensure that the students are actually finding the Library's e-resources and using them effectively and efficiently. This presentation won't focus as much on software, although we will be discussing what we use, it's more about how to use the software to teach InfoLit online effectively. We will conclude with a discussion on how to beta-test your new online approach to Information Literacy Instruction before launching it live for the students. So, come to this session and see how two northern (Ontario and Yukon) librarians are devising new and alternative methods of reaching out to students via a variety of methods and assessing their efforts. How, in fact, we have to examine "every angle" such as mode of delivery, type of student, pedagogical theory, etc. to ensure that we are serving our diverse populations well and contributing to the retention and success of these students

Family Proximity, Childcare, and Women's Labor Force Attachment

We show that close geographical proximity to mothers or mothers-in-law has a substantial positive effect on the labor supply of married women with young children. We argue that the mechanism through which proximity increases labor supply is the availability of childcare. We interpret availability broadly enough to include not only regular scheduled childcare during work hours but also an insurance aspect of proximity (e.g., a mother or mother-in-law who can provide irregular or unanticipated childcare). Using two large datasets, the National Survey of Families and Households and the public use files of the U.S. Census, we find that the predicted probability of employment and labor force participation is 4-10 percentage points higher for married women with young children living in close proximity to their mothers or their mothers-in-law compared with those living further away.

Proximity and Coresidence of Adult Children and their Parents: Description and Correlates

The ability of family members to engage in intergenerational transfers of hands-on care requires close proximity or coresidence. In this paper we describe and analyze the patterns of proximity and coresidence involving adult children and their mothers using data from the National Survey of Families and Households (NSFH) and the U.S. Census. Although intergenerational coresidence has been declining in the United States, most Americans live within 25 miles of their mothers. In both the raw data and in regression analyses, the most robust predictor of proximity of adult children to their mothers is education. Individuals are less likely to live near their mothers if they have a college degree. Virtually all previous studies have considered coresidence alone, or else treat coresidence as a limiting case of close proximity. We show that this treatment is misleading. We find substantial differences in the correlates of proximity by gender and marital status, indicating the need to model these categories separately. Other demographic variables such as age, race and ethnicity also affect the probability of coresidence and close proximity, but characteristics indicating a current need for transfers (e.g., disability) are not correlated with close proximity.

Why Are Power Couples Increasingly Concentrated in Large Metropolitan Areas

Using census data, Costa and Kahn (QJE, 2000) find that power couples - couples in which both spouses have college degrees - are increasingly likely to be located in the largest metropolitan areas. One explanation for this trend is that college educated couples are more likely to face a co-location problem - the desire to satisfy the career aspirations of both spouses - and therefore are more attracted to large labor markets than are other couples. An alternative explanation is that all college educated individuals, married and unmarried, are attracted to the amenities and high returns to education found in large cities and that as a result, the formation of power couples through marriage of educated singles and additional education is more likely to occur in larger than smaller metropolitan areas. Using the Panel Study of Income Dynamics (PSID), we analyze the dynamic patterns of migration, marriage, divorce and education in relation to city size and find that power couples are not more likely to migrate to the largest cities than part-power couples or power singles. Instead, the location trends are better explained by the higher rate of power couple formation in larger metropolitan areas. Regression analysis suggests that it is only the education of the husband and not the joint education profile of the couple that affects the propensity to migrate to large metropolitan areas.
