Delivery capabilities impact project performance
The aim of this research is to study project delivery capabilities impact project performance. If the companies know the factors that influencing the projectâs performance, they will focus on that and can deliver the project successfully. For the factors of project delivery capabilities is a set as independent variable. The factors that have been use in this research are process, organizations, methods, metric and leaderships because these are the top five factors that have impact on project performance. Then, the dependent variable of project performance is time. Sixty respondents from the construction industry in Kuantan, Pahang that are registered under CIDB were surveyed by questionnaire. The questionnaires were distributed using mail, google doc, and face to face. Software SPSS was use to analyse the data to get the results. The objectives of this research are to investigate project delivery capabilities practices in project management and to rank the project delivery capabilities according to priorities in project performance Results show that project delivery capabilities impact project performance and the finding are parallel accordance with previous researches but had different ranking of factors
Variability in the Implementation of State-Wide Law across Urban Environments: A Case Study using Sex Offender Law as an Example
CPACS Urban Research Awards
Part of the mission of the College of Public Affairs and Community Service (CPACS) is to conduct research, especially as it relates to concerns of our local and statewide constituencies. CPACS has always had an urban mission, and one way that mission is served is to preform applied research relevant to urban society in general, and the Omaha metropolitan area and other Nebraska urban communities in particular. Beginning in 2014, the CPACS Dean provided funding for the projects with high relevance to current urban issues, with the potential to apply the findings to practice in Nebraska, Iowa, and beyond
Effects of skeletal streetscape design on perceived safety
It is important for planners and urban designers to understand how physical characteristics of urban streetscapes contribute to perceptions of them as safe, comfortable urban spaces. While urban design theory offers numerous suggestions for successful streetscapes there is meager empirical evidence of their effects. We suggest that this is largely due to precision and sample size limitations on audit-based physical design and human perception measurements. This paper overcomes these limitations by identifying a key set of streetscape skeleton design variables that can be efficiently measured using a GIS-based method. It then measures these variables on a large and diverse sample of streetscapes, and examines their relationship to crowdsourced perceived safety scores, a useful indicator of environmental comfort. Regression modeling indicates that factors related to streetscape enclosure have a substantial positive effect on perceived safety. These include street tree canopy, the number of buildings along a block, and the cross-sectional proportion-the ratio of building height to width across the street between building façades. Importantly, these streetscape-scale skeleton variables have greater effect than neighborhood-scale urban form and affluence measures that are commonly used to identify desirable urban environments. Planning practitioners can draw on our results to set priorities for urban forestry and design guidelines that shape the spatial proportions of streetscapes and their success as spaces that feel safe and comfortable for human users
Forced Interactions with Sheriff Deputies Over Time and Their Influence on Stigma and Self Identities Among Individuals Convicted of Sex Crimes
This paper examined the perceptions of convicted sex offenders and their interactions with law enforcement over time. Specifically, we focused on how formal interactions influenced stigma management and self-identity transformation. For decades, scholars have proposed that identities and behaviors often result from interactions with others. Sex offender registration and notification laws force interactions between registrants and police agents for years, if not a lifetime. Given that desistance from sex offending is dependent on prosocial identity transformation, we analyzed interviews with 63 registrants to uncover how interactions with police promote or inhibit identity transformation over time. Our findings suggested interactions with police can influence the internalization of a âsex offenderâ label, can reaffirm non-offender role identities, but mostly have little to no effect on personal identity transformation over time
My funky genetics : BRCA1/2 mutation carriers\u27 understanding of genetic inheritance and reproductive merger in the context of new reprogenetic technologies
Deleterious mutations in the BRCA1/BRCA2 genes elevate lifetime risk of breast and ovarian cancer. Each child of a mutation-positive parent has a 50% chance of inheriting it. Preimplantation genetic diagnosis (PGD) permits prospective parents to avoid the birth of a BRCA-mutation-positive child, introducing predictability into a process historically defined by chance. This investigation explored how BRCA1/2 mutation carriers understand genetic inheritance and consider a child\u27s inheritance of a BRCA1/2 mutation, given the opportunities that exist to pursue PGD. Thirty-nine female and male BRCA1/2 mutation carriers of reproductive age were recruited from urban cancer and reproductive medical centers. Participants completed a standardized educational presentation on PGD and prenatal diagnosis, with pre-and posttest assessments. An interdisciplinary team of qualitative researchers analyzed data using grounded theory techniques. Participants expressed the belief that reproduction yields children with unique genetic strengths and challenges, including the BRCA1/2 mutation, family traits for which predictive tests do not exist, and hypothetical genetic risks. Participants expressed preference for biologically related children, yet stated their genetically well partner\u27s lineage would be marred through reproductive merger, requiring the well partner to assume the burden of the BRCA1/2 mutation via their children. Participants expressed diverse views of genetically well partners\u27 participation in family planning and risk management decisions. Pressure to use reprogenetic technology may grow as genetic susceptibility testing becomes more widely available. Work with individuals and couples across the disease spectrum must be attuned to the ways beliefs about genetic inheritance play into reproductive decision-making.

No Correlation Between Host Galaxy Metallicity and Gamma-Ray Energy Release for Long-Duration Gamma-Ray Bursts
We compare the redshifts, host galaxy metallicities, and isotropic
(E_gamma,iso) and beaming-corrected (E_gamma) gamma-ray energy release of 16
long-duration gamma-ray bursts (LGRBs) at z < 1. From this comparison, we find
no statistically significant correlation between host metallicity and redshift,
E_gamma,iso, or E_gamma. These results are at odds with previous theoretical
and observational predictions of an inverse correlation between gamma-ray
energy release and host metallicity, as well as the standard predictions of
metallicity-driven wind effects in stellar evolutionary models. We consider the
implications that these results have for LGRB progenitor scenarios, and discuss
our current understanding of the role that metallicity plays in the production
of LGRBs.Comment: 13 pages, 1 figure; accepted to Astrophysical Journa
Vision Care Utilization and Insurance Coverage Prior to and Following Medicaid Expansion in Ohio
Background: Increased access and utilization of vision care services has the potential to reduce preventable vision loss. The state of Ohio has been uniquely proactive when collecting vision-oriented data through population health surveys, including the Behavioral Risk Factor Surveillance System (BRFSS). These data can be used to better understand vision care utilization patterns and access to insurance.
Methods: Responses to 3 items administered in the Ohio BRFSS that assess vision care utilization and insurance coverage were compared between 2 different administration periods, 2005-2011 and 2018-2019, using chi-square tests. Comparable data from 2 items assessing eye care utilization were available in 2005-2011 and 2019. Comparable data for insurance coverage were available in 2005-2011 and in 2018-2019. Responses were further stratified by population characteristics, including age, gender, household income, and education level.
Results: The percentages of those reporting eye exams in the previous year were not significantly different between 2005-2011 and 2019 (chi-square, p = 0.06). In Ohio, the primary reason for not seeing a vision care provider in the past 12 months was âNo reason to goâ in 2005-2011 and in 2019. The second most common reason for not seeing a vision care provider in the past 12 months was âCost/insurance,â which decreased between 2005-2011 and 2019 (chi-square, p <0.001). Insurance coverage for eye care increased between 2005-2011 and 2018-2019 (chi-square, p <0.001). Important differences were found within the demographic stratification.
Conclusion: Population health surveillance data provide useful insight into vision care utilization and insurance coverage. Despite the increase in insurance coverage, eye care provider utilization remains relatively stable

GRB 090426: The Environment of a Rest-Frame 0.35-second Gamma-Ray Burst at Redshift z=2.609
We present the discovery of an absorption-line redshift of z = 2.609 for GRB
090426, establishing the first firm lower limit to a redshift for a gamma-ray
burst with an observed duration of <2 s. With a rest-frame burst duration of
T_90z = 0.35 s and a detailed examination of the peak energy of the event, we
suggest that this is likely (at >90% confidence) a member of the short/hard
phenomenological class of GRBs. From analysis of the optical-afterglow spectrum
we find that the burst originated along a very low HI column density sightline,
with N_HI < 3.2 x 10^19 cm^-2. Our GRB 090426 afterglow spectrum also appears
to have weaker low-ionisation absorption (Si II, C II) than ~95% of previous
afterglow spectra. Finally, we also report the discovery of a blue, very
luminous, star-forming putative host galaxy (~2 L*) at a small angular offset
from the location of the optical afterglow. We consider the implications of
this unique GRB in the context of burst duration classification and our
understanding of GRB progenitor scenarios.Comment: Submitted to MNRA
Geocoding rural addresses in a community contaminated by PFOA: a comparison of methods
BACKGROUND: Location is often an important component of exposure assessment, and positional errors in geocoding may result in exposure misclassification. In rural areas, successful geocoding to a street address is limited by rural route boxes. Communities have assigned physical street addresses to rural route boxes as part of E911 readdressing projects for improved emergency response. Our study compared automated and E911 methods for recovering and geocoding valid street addresses and assessed the impact of positional errors on exposure classification. METHODS: The current study is a secondary analysis of existing data that included 135 addresses self-reported by participants of a rural community study who were exposed via public drinking water to perfluorooctanoate (PFOA) released from a DuPont facility in Parkersburg, West Virginia. We converted pre-E911 to post-E911 addresses using two methods: automated ZP4 address-correction software with the U.S. Postal Service LACS database and E911 data provided by Wood County, West Virginia. Addresses were geocoded using TeleAtlas, an online commercial service, and ArcView with StreetMap Premium North America NAVTEQ 2008 enhanced street dataset. We calculated positional errors using GPS measurements collected at each address and assessed exposure based on geocoded location in relation to public water pipes. RESULTS: The county E911 data converted 89% of the eligible addresses compared to 35% by ZP4 LACS. ArcView/NAVTEQ geocoded more addresses (n = 130) and with smaller median distance between geocodes and GPS coordinates (39 meters) than TeleAtlas (n = 85, 188 meters). Without E911 address conversion, 25% of the geocodes would have been more than 1000 meters from the true location. Positional errors in TeleAtlas geocoding resulted in exposure misclassification of seven addresses whereas ArcView/NAVTEQ methods did not misclassify any addresses. CONCLUSIONS: Although the study was limited by small numbers, our results suggest that the use of county E911 data in rural areas increases the rate of successful geocoding. Furthermore, positional accuracy of rural addresses in the study area appears to vary by geocoding method. In a large epidemiological study investigating the health effects of PFOA-contaminated public drinking water, this could potentially result in exposure misclassification if addresses are incorrectly geocoded to a street segment not serviced by public water
