Maneuver planning and evaluation procedures, data and analysis results for all maneuvers performed to date, the frozen orbit concept, and the phasing requirement between LANDSAT-4 and LANDSAT-5 are also examined

Technologies to Enhance Optimal Glycemic Control in Young Adults with Type 1 Diabetes

Background People with type 1 diabetes make up approximately two million of the American population. Every day, these two million people struggle to fight this lifelong, sometimes life threatening disease. While type 1 diabetes currently has no cure, there are technologies that can make diabetes management more effective. This study surveyed the type 1 diabetes (T1D) young adult population aged 18-30, to evaluate what technologies and tools are most often associated with achieving optimal glycemic control (OGC). Methodology The instrument is a 35 question, investigator developed survey that is designed to measure how often a participant utilizes the technology identified in each question, with the response choices ranging from 0 (never) to 5 (multiple times daily). In addition, there were some yes/no and fill-in-the-blank questions to identify demographic variables. The technology topics that were explored are 1) mode of insulin therapy, 2) mode of blood glucose monitoring therapy, 3) mode of communication with designated care provider, 4) electronic applications used, 5) demographic variables, and 6) pertinent comorbidities. This information was used to evaluate variables that assist T1Ds in achieving optimal glycemic control. Participants were invited to participate in this study via email using the Students with Diabetes email listserv. The email contained the IRB approved explanation of research letter, which informed participants of the study and the research being conducted. If the student chose to participate, they checked a box that served as an electronic signature, and they continued on to the 35-question survey. All responses to the survey will be kept confidential; as the survey and research did not require any personal identifying information. Data regarding the specific demographics, technologies used for diabetes control, and hemoglobin A1C levels were recorded and analyzed. The results of the survey will be shared with the participants via the same email list-serv by which they were originally recruited. Results There were 59 participants. A total of 21 out of 59 respondents had optimal glycemic control (A1C less than 7.0, per American Diabetes Association guidelines). Eighty eight percent of those with OGC wore their CGMs all the time, while only 66% of those with IGC wore their CGMs all the time. Ninety five percent of those with OGC used their insulin pumps all the time, while 89% of those with IGC did. It is likely that the combination of both CGMs and insulin pumps worn all the time are the most powerful tools to achieving OGC. Students that were employed, enrolled in classes, and still under their parent’s insurance plans had a higher incidence of optimal glycemic control. Discussion It was hypothesized that those with OGC would have a higher incidence of diabetes technology use. This PI found that even though almost all participants had access to the diabetes technology, still only 37% of the participants had optimal glycemic control. There are many components to diabetes care that impact glycemic control that were not explored within this scope of this diabetes technology study. Conclusions It is likely that both CGMs and insulin pumps worn all the time are the most powerful tools to achieving OGC. Students who graduate from college and transition to adulthood are vulnerable as they may encounter added stressors such as employment, and financial responsibility that cause them to deviate from the recommendations for diabetes technology use. Care providers need to be cognizant that young adulthood is a vulnerable time in terms of OGC and optimal diabetes management. Providers need to work with young adults, and encourage them to adhere to the recommended diabetes care regime

How employers respond to employees who return to the workplace after experiencing the death of a loved one? A review of the literature

In order to provide insight for employers in maintaining a mentally healthy and productive workforce, it is essential to understand how bereaved employees experience workplace support. A global literature search was conducted between February 2018 and April 2018, resulting in 15 papers directly matching stipulated inclusion and exclusion criteria. Three common themes emerged from the data namely; Instrumental Support, Informational Support and Emotional Support. Findings suggest that while various employers endeavoured to show sympathy and flexibility to bereaved employees, others were found to be less responsive with certain areas of workplace support being reported as insufficient

Grieving in the workplace: How do grieving employees perceive their experience of workplace support from management?

To explore what bereaved employees consider as helpful support from their managers. An online questionnaire was completed by 40 participants from various occupations in the United Kingdom who had been bereaved of their spouse. The data were analysed using a qualitative thematic approach. Two key superordinate themes were found: Acknowledgement’ and ‘Response’. This study supports the growing initiative to set informal support for grieving employees thereby enhancing the provision of impactful and timely bereavement support in the workplace. These findings suggest that managers were considered to be supportive when they ‘acknowledged’ the bereaved employees’ situation and their reactions to grief. Additionally, managers were thought to be supportive when they responded in offering specific support depending on the individual’s circumstances and provided sufficient time and space for them to grieve. ‘Acknowledging’ and ‘responding’ appeared to promote understanding and instil a sense of being valued rather than the feeling of being just another number within the organisation. All participants were English speakers and a higher proportion were women, which may influence the generalisability of the findings

Log Fano varieties over function fields of curves

Consider a smooth log Fano variety over the function field of a curve. Suppose that the boundary has positive normal bundle. Choose an integral model over the curve. Then integral points are Zariski dense, after removing an explicit finite set of points on the base curve.Comment: 18 page

“So what about the stories?” An exploratory study of the definition, use, and function of narrative child sexual exploitation material (N-CSEM)

The legal and psychological research surrounding online Child Sexual Exploitation Material (CSEM) is focused on visual depictions of children, either as still images or movies. Narrative CSEM (N-CSEM) describes an under-researched area, resulting from difficulties surrounding its conceptualisation, both legally as well as concerning the function for its users. The current study describes an initial attempt in defining N-CSEM in comparison to visual material, based on interviews with users of CSEM and N-CSEM and professionals working with this user group. Thematic Analysis resulted in three super-ordinate themes. All themes were analysed and enriched from the perspectives of user- and service-representatives. The study provides insight into N-CSEM as a separate entity from visual CSEM, challenging and informing legal decision-making and assessment and treatment providers for users of CSEM

17beta-oestradiol and Enovid mammary tumorigenesis in C3H/HeJ female mice: counteraction by concurrent 2-bromo-alpha-ergocryptine.

Chronic administration of 17beta-oestradiol (via drinking water) or the oral contraceptive Enovid (norethynodrel and mestranol) (0-1 mg injected s.c. twice weekly) to nulliparous C3H/HeJ female mice, beginning at one month of age and terminating at 20 months (17beta-oestradiol) or 22 months (Enovid), significantly increased the incidence of mammary tumours over solvent-treated controls. Concurrent treatment of the steroid-treated mice with 2-bromo-alpha-ergocryptine (CB-154) (0-1 mg s.c. injected daily) significantly reduced mammary tumour incidence and mammary hyperplastic nodule development to the control level. CB-154 is an efficacious inhibitor of pituitary prolactin secretion. These results demonstrate that steroid-induced mammary gland dysplasias can be sharply reduced by chronic CB-154 treatment, and suggest that some of the mammary tumorigenic activities of oestrogenic steroids in C3H mice are mediated via an increased secretion of pituitary prolactin
