Population and land use change in the California Mojave: Natural habitat implications of alternative futures

Demographic and land use dynamics have important implications for the natural environment within both developed and developing nations. Within the context of developed nations, popular and policy debates surrounding contemporary patterns of suburbanization attest to the salience of demographic and development issues. We examine the implications of land-use patterns as related to population and development within the context of the California Mojave Desert ecosystem. In a general sense, we aim to better understand the land requirements inferred by varying levels of population growth and density, as well as the natural habitat implications of those requirements. We develop a GIS including remotely sensed imagery, and demographic, economic, and biophysical data to examine of the implications of various demographic scenarios on species diversity. Spatial and statistical models are designed to develop possible alternative land use `futures'. Within the context of the California Mojave region, our results suggest that high-density development could reduce conflict with regions providing potential habitat for threatened or endangered species by over 80 percent. The process of model development demonstrates a potentially useful tool for policymakers, allowing for estimation and visualization of the land use implications of policy decisions.     

Factorial ecology: A critique and some suggestions

Studies in factorial ecology have typically used the principal factor procedure coupled with varimax rotation. Since it can be shown that the results one obtains vary according to the factor and rotation models he employs, and since there is no one “best” way of obtaining initial and derived factor solutions, it is proposed that future research in the area adopt an approach involving the simultaneous use of several different computing algorithms for obtaining initial solutions and both orthogonal and oblique rotation procedures to avoid the possibility that the results one obtains are not method-dependent. Ideally, the factor models employed should differ maximally with respect to the principles upon which they are based. If one finds a given factor regardless of the method he uses, only then can he assert with any confidencethat it is not an artifact of his method. Factorial ecologists are often interested in computing “factor scores”, but “true” factor scores are not uniquely computable; they can only be estimated. Since the proposed research strategy involves using either a component or an image model, in which the corresponding scores are exact and uniquely computable, the factor score problem is, in a sense, solved. Next it is suggested that, by using orthogonal solutions, factorial ecologists may be overlooking a very important piece of information—the correlation between the factors. There is some reason to believe that this varies from city to city, and may account for the fact that some factors which emerge in studies of Western cities are sometimes not found in cities elsewhere. Some comments are also made on the value of using census tract data, and on the availability of computer programs for different initial and derived factor solutions.     

“Trying to be positive in the face of the storm”: The experiences of independent college students during the COVID-19 pandemic

The COVID-19 pandemic created multiple stressors for college students, particularly for young adults experiencing multiple forms of disadvantage. Little is known about the pandemic experiences of independent college students, many of whom are emancipated minors, former wards of the state, and other students who lack familial financial and practical support as they pursue higher education. Twenty-three independent students, ages 18–23, from one northeastern university were interviewed to understand how independent students were affected by the COVID-19 pandemic, and their needs for support from the university during this time. Most participants were identified as Black or Latinx, and two thirds were first-generation college students. Participants reported an overall lack of support from their families prior to the pandemic. During the pandemic, they experienced compounding academic, economic, and mental health-related stressors. Students responded to these stressors in resilient and resourceful ways, by adapting to their new realities, expressing gratitude, and finding opportunities for self-growth. Participants recommend that institutions of higher education support independent students during periods of emergency through providing financial assistance, offering opportunities for connection with both adults and peers, and demonstrating administrative flexibility and understanding of their unique needs.     

An Ethical Analysis of the Second Amendment: The Right to Pack Heat at Work

We examine the issues concerning the legality and ethicality of the Second Amendment right to bear arms balanced by the employer's duty to provide a safe workplace for its employees. Two court rulings highlight this balancing act: McDonald et al. v. City of Chicago et al. and District of Columbia v. Heller. “Stand Your Ground” and “Castle Doctrine” laws in the recent Trayvon Martin shooting on February 26, 2012 are also applicable. Various ethical frameworks examine the firearms debate by viewing the Second Amendment from three perspectives. These include a pro‐gun perspective drawing upon libertarianism and fundamental rights; a moderate gun perspective drawing upon consequentialism and stakeholder theory; and finally, an anti‐gun perspective drawing upon a Public Health Ethics and peace ethics approach. We explore the issue of gun control from a business perspective as employers face ethical decisions in responding to legislation that allows guns in the workplace and/or in employer parking lots while still being responsible to provide a safe workplace for their employees. We make recommendations regarding how companies should manage by proactively avoiding legal challenges to employees' rights to own and carry guns into the workplace. This includes emphasis on enhanced security, Human Resource policies and monitoring rapidly changing laws.
