What Determines Family Structure?

We estimate the effects of policy and labor market variables on the fertility, union formation and dissolution, type of union (cohabiting versus married), and partner choices of the NLSY79 cohort of women. These demographic behaviors interact to determine the family structure experienced by the children of these women: living with the biological mother and the married or cohabiting biological father, a married or cohabiting step father, or no man. We find that the average wage rates available to men and women have substantial effects on family structure for children of black and Hispanic mothers, but not for whites. The tax treatment of children also affects family structure. Implementation of welfare reform and passage of unilateral divorce laws had much smaller effects on family structure for the children of this cohort of women, as did changes in welfare benefits. The estimates imply that observed changes from the 1970s to the 2000s in the policy and labor market variables considered here contributed to a reduction in the proportion of time spent living without a father by children of the NLSY79 cohort of women. This suggests that the observed increase in this non-traditional family structure in the U.S. in the last three decades was caused by other factors.family structure

Assessment of Public Awareness on Cyber Complexity when Using of Social Media Platforms in Tanzania: A Case of Kigamboni Municipality

The study was conducted at Kigamboni Municipal to assess the public awareness on cyber complexity when using social media platforms. Specifically the study was interested to determine the level of public awareness of various cyber complexities and risks associated with using social media platforms, to examine the ways used by the government and other stakeholders in creating public awareness on cyber complexity when using social media platforms, and to understand the attitude and perceptions of the public towards cyber complexities in social media use. The study collected information from a number of 100 respondents who were selected through random and purposive sampling techniques. Interview and questionnaires were used as tools for data collection. The study revealed that respondents were in majority using social media platforms and Instagram was the most social media platforms used. The study revealed that most of respondents were not knowledgeable about cyber bullying and its associated laws and policies. The study also revealed that there was little effort conducted by the government and other stakeholder in conducting campaigns aiming at creating awareness about cyber-crimes associated with social media platforms. The study was interested is finding out measures that could be used taken to improve public awareness on cyber complexity when using social media. a large number of respondents proposed the need for conducting education in schools and higher learning institution.. Unless the government furnish many efforts in introducing the proper use of social media in school curricula in all schools and higher learning institutions still the efforts done by the police is minimal compared to the influence of social media

Test cornfields for nitrate if manure was not incorporated

Research during the past few years has shown that severe deficiencies of nitrogen (N) are common in fields where manure was applied without immediate incorporation. Data gathered in 2001 continue to support this conclusion and emphasize the need to use the late-spring test to check nitrate levels in such fields. Immediate incorporation of manure into soil is an effective way to reduce odor and losses of N soon after application. Incorporation reduces volatilization of ammonia, which can be a serious problem if manure is spread after it has been stored in pits or piles

Save nitrogen dollars after manure

Precision farming trials last year confirmed the old idea that manure can be a valuable source of nitrogen (N) for corn production. The results deserve special attention when both fertilizer N prices and environmental concerns are high. The trials were made possible by funding from the Iowa Corn Promotion Board and were conducted at 11 sites having an average size of 20 acres

Estimation of fiber diameters in the spinal dorsal columns from clinical data

Lack of human morphometric data regarding the largest nerve fibers in the dorsal columns (DCs) of the spinal cord has lead to the estimation of the diameters of these fibers from clinical data retrieved from patients with a new spinal cord stimulation (SCS) system. These patients indicated the perception threshold of stimulation induced paresthesia in various body segments, while the stimulation amplitude was increased. The fiber diameters were calculated with a computer model, developed to calculate the effects of SCS on spinal nerve fibers. This computer model consists of two parts: (1) a three-dimensional (3-D) volume conductor model of a spinal cord segment in which the potential distribution due to electrical stimulation is calculated and (2) an electrical equivalent cable model of myelinated nerve fiber, which uses the calculated potential field to determine the threshold stimulus needed for activation. It is shown that the largest fibers in the medial DCs are significantly smaller than the largest fibers in the lateral parts. This finding is in accordance with the fiber distribution in cat, derived from the corresponding propagation velocities. Moreover, it is shown that the mediolateral increase in fiber diameter is mainly confined to the lateral parts of the DCs. Implementation of this mediolateral fiber diameter distribution of the DCs in the computer model enables the prediction of the recruitment order of dermatomal paresthesias following increasing electrical stimulation amplitud

Qualitative Exploration of Case Conferencing and Occupational Stress with Video Relay Interpreters

American Sign Language (ASL) interpreters working in Video Relay Service (VRS) call centers experience more occupational stress than interpreters working in community settings, leading to burnout, attrition, and loss of qualified interpreters for the Deaf and hard of hearing community. Case conferencing that incorporates the use of demand control schema (DC-S; Dean & Pollard, 2001) is an emergent strategy that may be effective in decreasing VRS interpreters’ stress and burnout but has yet to be thoroughly studied. The purpose of this exploratory, qualitative case study is to understand how participation in an adapted DC-S case conferencing group assisted VRS interpreters reducing occupational stress and attrition in VRS. Data from this study yielded four major themes: (1) reduction of occupational stress, (2) application of skills learned in groups, (3) integration into practice, and (4) retention in VRS. Although not a distinct theme, improvement in call center culture emerged as an additional finding. Our findings suggest that case conferencing is a helpful strategy to manage stressors that are unique to working in VRS and can promote interpreter retention
