Performing the Other: Indigenous Identity and Regional Resistance in Sonoran Literature of the 1980\u27s
During the decade of the 1980âs there occurs a preoccupation, presence and notable change in the representation of the indĂgena in the cultural production of the State of Sonora. This articulation of a modified ethnic discourse is a product of the economic and social changes that impacted the region during this period. Through a detailed examination of three Sonoran writers we observe how this ethnic discourse leads to a reformulation the traditional images of the indĂgena and reflects the negotiation between local and national interests to determine the meaning of the region, its identity and its place within the nation
Textiled Narratives: Branding, Consumption, and Mexican American Identity at the Turn of the Twentieth Century
The NaCo apparel company out of Tijuana, Mexico, created a unique line of clothing and accessories in the late 1990s and early 2000s. With its success in Mexico, the brand chose to extend its reach into the lucrative US market. The company\u27s focus on bicultural and binational images seemed a natural fit for a growing Latinx presence in the US. An analysis of the company\u27s successes and failures in the new market highlights the continued importance of borders as separators of visual economies rooted in national histories and imaginations. Additionally, their experience reveals the complexities within Latinx communities that can at once divide and unite them. This pushes back against prevalent discourses that tend toward homogenizing the political and cultural beliefs in these communities
The Human Resource Implications of Plant Shutdowns
Human resource programs that were developed to serve those displaced by plant closings have been fragmented. Participation rates have been low in placement, job search assistance, relocation, and retrain ing programs, and results have not been particularly positive. Great emphasis was placed upon serving those in need when programs did develop. The fragmentation characteristic of previous policyâor nonpolicyâ seems to have undergone considerable organization and rationalization with the advent of the Job Training Partnership Act (JTPA) and the association of several major labor-management displaced worker pro grams with the federal-state program. This change tends to emphasize placement and to focus upon training exclusively. As a result, not only will disadvantaged workers compete with displaced workers for training resources and jobs, but participation in programs for displaced workers will be encouraged for those who are most advantaged, thus consigning a large number of less-advantaged displaced workers to underemployment, permanent unemployment, and eventual dependence upon income main tenance.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/67203/2/10.1177_000271628447500106.pd

Reactions of HighâEnergy, Excited I128 Ions with Gaseous Molecules
The manner in which molecular additives inhibit the reaction of (n, Îł) activated I128 with CH4 was determined in an effort to observe indirectly reactions of I128 with the additives. The data suggest that (1) O2, N2, and CF4 serve only to remove excess I128 kinetic energy; (2) the ionization potential of O2 is greater than 12.16 ev, the potential energy of I+(1D2); (3) the ionization potential of C2F6 is less than 12.16 ev; (4) CH3I, CF3I, nâC3H7I, and C6H6 inhibit the reaction principally as a result of I++additive ionâmolecule reactions and/or physical quenching.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/70530/2/JCPSA6-36-2-287-1.pd
C13 and Deuterium Isotope Effects in the Photolysis of Methyl and Ethyl Bromide
Relative rates of formation of isotopic radicals in the photolysis of gaseous methyl and ethyl bromide have been measured. Photolyses (2537 A) were carried out in a large excess of cyclopentane. Methyl (or ethyl) radicals formed in the primary CâBr bond scission abstract H from cyclopentane to form methane (or ethane). For methyl bromide, the C12/C13 enrichment factor for the first fraction of the methane was 1.039±0.003. The corresponding factor for the αâcarbonâBr rupture in ethyl bromide was 1.041±0.004. In the deuterium experiments, CH3BrâCD3Br mixtures in excess cyclopentane were photolyzed. The H/D fractionation factor (based on CH4/CD3H) was 1.41±0.01.The difference in rates of formation of isotopic radicals is due to the difference in ultraviolet absorption coefficients of the isotopic alkyl bromides. At 2537 A the observed ratio of the extinction coefficient of CH3Br relative to that of CD3Br is 1.38±0.05.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/71079/2/JCPSA6-30-4-973-1.pd
Failure to Bond Rupture and Nuclear Recoil Following (n, Îł) Activation
Following the absorption of a thermal neutron by 127I or 79Br, the neutronâbinding energy is frequently released in the form of a gammaâray cascade. As a result of partial cancellation of gammaâray momenta, a small fraction of the activated halogens will not receive sufficient recoil momentum to rupture from their parent compound. The gasâphase failures to bond rupture following 127I(n, Îł) 128I, and 79Br(n, Îł) 80Br activation were found experimentally to be: CH3Iâ1.09, CD3Iâ0.68, CF3Iâ0.12, CH2I2â0.068, C2H5Iâ0.082, nâC3H7Iâ0.66, iâC3H7Iâ0.30, CH3Brâ0.25, CD3Brâ0.20, CH2Br2â0.12, CF3Brâ0.11, CF2Br2â0.093, CHClBr2â0.087, CCl3Brâ0.066, CHBr3â0.05, CBr4â0.03, C2H5Brâ0.33, and 1,1âC2H4Br2â0.17%. These data are correlated with the calculated recoil energies required for bond rupture (preceding article). Using as a basis the distribution of net gammaâray energies calculated by the randomâwalk method for the 35Cl(n, Îł) 36Cl process, the kineticâenergy distributions of the dissociated 128I or 80Br are approximated. These data suggest that the extent of hotâatom reaction of 128I or 80Br with CH4 should not depend upon the parent molecule from which the activated halogen dissociates.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/69788/2/JCPSA6-36-4-954-1.pd
