Gay Parenthood and the Revolution of the Modern Family: An Examination of the Unique Barriers Confronting Gay Adoptive Parents

Abstract: In recent decades, the structure of the American family has been revolutionized to incorporate families of diverse and unconventional compositions. Gay and lesbian couples have undoubtedly played a crucial role in this revolution by establishing families through the tool of adoption. Eleven adoptive parents from the state of Connecticut were interviewed to better conceptualize the unique barriers gay couples encounter in the process adoption. Both the scholarly research and the interview data illustrate that although gay couples face enormous legal barriers, the majority of their hardship comes through social interactions. As a result, the cultural myths and legal restrictions that create social hardships for gay adoptive parents forge a vicious and discriminatory cycle of marginalization that American legal history illustrates is best remedied through judicial intervention at the Supreme Court level. While judicial intervention, alone, cannot change the reality of gay parenthood, I argue that past judicial precedent illustrates that such change can serve as a tool of individual, political, and legal validation for the gay community for obtaining equal rights.

The impact of functional impairment on the survival of patients with Alzheimer's disease

Alzheimer's disease (AD), the most common form of dementia, is the fifth leading cause of death among U.S. adults aged 65 or older. Most AD patients have shorter life expectancy compared with older people without dementia. This disease has become an enormous challenge in the aging society and is also a global problem. Not only do families of patients with Alzheimer's disease need to pay attention to this problem, but also the healthcare system and society as a whole have to confront. In dementia, functional impairment is associated with basic activities of daily living (ADL) and instrumental activities of daily living (IADL). For patients with Alzheimer's disease, problems typically appear in performing IADL and progress to the inability of managing less complex ADL functions of personal care. Thus, assessment of ADLs can be used for early accurate diagnosis of Alzheimer's disease. It should be useful for patients, caregivers, clinicians, and policy planners to estimate the survival of patients with Alzheimer's disease. However, it is unclear that when making predictions of patient outcome according to their histories, time-dependent covariates will provide us with important information on how changes in a patient's status can effect the survival. In this study, we examined the effect of impaired basic ADL as measured by the Physical Self-Maintenance Scale (PSMS) and utilized a multistate survival analysis approach to estimate the probability of death in the first few years of initial visit for AD patients taking into consideration the possibility of impaired basic ADL. The dataset used in this study was obtained from the Baylor Alzheimer's Disease and Memory Disorders Center (ADMDC). No impaired basic ADL and older age at onset of impaired basic ADL were associated with longer survival. These findings suggest that the occurrence of impaired basic ADL and age at impaired basic ADL could be predictors of survival among patients with Alzheimer's disease. ^

Translation and cultural adaptation of the Stigma-Devaluation scale for use among family caregivers of mentally ill relatives in Jordan

Background/significance. Mental illness stigma is a matter of great concern to family caregivers. Few research studies have been conducted in the Arab World on family caregivers' perception of stigma associated with caring for a mentally ill relative. Review of the literature on measurement of the concept of stigma related to caring for a mentally ill relative yielded no instrument appropriate for use in a Jordanian sample. Reliable and valid instruments to measure stigma perception among family caregivers are needed for research and practice, particularly in Arabic speaking populations. ^ Purpose. The purposes of this study were: (1) translate the Stigma-Devaluation scale (SDS) into Arabic, modifying it to accurately reflect the cultural parameters specific to Jordan, and (2) test the reliability, the content and construct validity of the Arabic version of the SDS for use among a sample of family members of mentally ill relatives in Jordan. ^ Design. Methodologic, cross-sectional. ^ Methods. The SDS was translated into Arabic language, modified and culturally adapted to the Jordanian culture by a translation model which incorporates a cultural adaptation process. The Arabic SDS was evaluated in a sample of 164 family caregivers in the outpatient mental health clinic in Irbid-Jordan. Cronbach's alpha estimation of internal consistency was used to assess the reliability of the SDS. Construct validity was determined by confirmatory factor analysis (CFA). Measurements of content validity and reading level of the Arabic SDS were included. ^ Findings. Content Validity Index was determined to be 1.0. Reading level of the Arabic SDS was considered at a 6th grade or lower Cronbach's alpha coefficient of the modified Arabic SDS total scale was .87. Initial results of CFA did not fully support the proposed factor structures of the SDS or its subscales. After modifications, the indices indicated that the modified model of each subscale had satisfactory fit. ^ Conclusion. This study provided psychometric evidence that the modified Arabic SDS translated and culturally adapted instrument, is valid and conceptually consistent with the content of the original English SDS in measuring stigma perception among families of mentally ill relatives in Jordan. ^

Genetic epidemiology of childhood brain tumors

A rare familial cancer syndrome involving childhood brain tumors (CBT), breast cancer, sarcomas and an array of other tumors has been described (Li and Fraumeni 1969, 1975, 1982, 1987). A survey of CBT identified through the Connnecticut Tumor Registry in 1984 revealed a high frequency of CBT, leukemia and other childhood cancer in siblings of CBT patients (Farwell and Flannery, 1984). Other syndromes such as neurofibromatosis and nevoid basal cell carcinoma syndrome have also been associated with CBT; however, no systematic family studies have been conducted to determine the extent to which cancer aggregates in family members of CBT patients. This family study was designed to determine the frequency of cancer aggregation overall or at specific sites, to determine the frequency of known or potentially hereditary syndromes in families of CBT patients, and to determine a genetic model to characterize familial cancer syndromes and to identify specific kindreds to which such a model(s) might apply. This study includes 244 confirmed CBT patients referred to the University of Texas M. D. Anderson Cancer Center between the years 1944 and 1983, diagnosed under the age of 15 years and resident in the U.S. or Canada. Family histories were obtained on the proband's first (parents, siblings and offspring) and second degree (proband's aunts, uncles and grandparents) relatives following sequential sampling scheme rules. To determine if cancer aggregates in families, we compared the cancer experience in the population to that expected in the general population using Connecticut Tumor Registry calendar year, age, race and sex-specific rates. The standardized incidence ratio (SIR) for cancer overall was 0.91 (41 observed (O) and 44.94 expected (E); 95% Confidence Interval (CI) = 0.65-1.24). We observed a significant excess of colon cancer among the proband's first degree relatives (O/E = 5/1.64; 95% CI = 1.01-7.65), in particular those under age 45 year. Segregation analysis showed evidence for multifactorial inheritance in the small percentage (N = 5) of the families. ^

THE LOGIC OF NOMINAL RECORD LINKAGE WITH A CASE STUDY FROM LAREDO, TEXAS

The Laredo Epidemiology Project is a study of the patterns of degenerative disease, particularly cancer, in the families of Laredo, Texas. The genealogical history of Laredo was reconstructed by the grouping of 350,000 individual church and civil vital event records into multi-generational families, with record linkage based on matching names. Mortality data from death records are mapped onto these pedigrees for analysis. This dissertation describes the construction of the data base and the logic upon which decisions were based. ^

Genetic underpinnings of variation in brain ventricular volume: A genome-wide association study

The ventricular system is a critical component of the central nervous system (CNS) that is formed early in the developmental stages and remains functional through the lifetime. Changes in the ventricular system can be easily discerned via neuroimaging procedures and most of the time it reflects changes in the physiology of the CNS. In this study we attempted to identify specific genes associated with variation in ventricular volume in humans. Methods. We conducted a genome wide association (GWA) analysis of the volume of the lateral ventricles among 1605 individuals of European ancestry from two community based cohorts, the Genetics of Microangiopathic Brain Injury (GMBI; N=814) and Atherosclerosis Risk in Communities (ARIC; N=791). Significant findings from the analysis were tested for replication in both the cohorts and then meta-analyzed to get an estimate of overall significance. Results. In our GWA analyses, no single nucleotide polymorphism (SNP) reached a genome-wide significance of p<10−8. There were 25 SNPs in GMBI and 9 SNPs in ARIC that reached a threshold of p<10 −5. However, none of the top SNPs from each cohort were replicated in the other. In the meta-analysis, no SNP reached the genome-wide threshold of 5×10−8, but we identified five novel SNPs associated with variation in ventricular volume at the p<10 −5 level. Strongest association was for rs2112536 in an intergenic region on chromosome 5q33 (Pmeta= 8.46×10−7 ). The remaining four SNPs were located on chromosome 3q23 encompassing the gene for Calsyntenin-2 (CLSTN2). The SNPs with strongest association in this region were rs17338555 (Pmeta= 5.28×10 −6), rs9812091 (Pmeta= 5.89×10−6 ), rs9812283 (Pmeta= 5.97×10−6) and rs9833213 (Pmeta= 6.96×10−6). Conclusions. This GWA study of ventricular volumes in the community-based cohorts of European descent identifies potential locus on chromosomes 3 and 5. Further characterization of these loci may provide insights into pathophysiology of ventricular involvement in various neurological diseases.^

Guardians of Generations: African American Grandparent Caregivers for Children of HIV/AIDS Infected Parents

Grandparents, particularly, grandmothers in the African American community have historically provided needed care for their grandchildren (Crewe, 2003). Before there was a child welfare system that addressed the needs of African American children, there were grandmothers who served as the safety net for their biological, informally adopted grandchildren, and other minor relatives. They cared for grandchildren and others whose birth parents were unable or unwilling to care for them. For families of color, HIV/AIDS is an emerging issue that is contributing to the growing numbers of grandparent-headed households. And once again, many African American grandmothers have accepted the challenge of holding their families together. This article addresses the HIV/AIDS public health challenge in the African American community with specific focus on its impact on older grandparents responsible for raising children of infected biological parents. It advocates for a model that continues to strengthen the Children’s Bureau investment in kinship care through integrating the needs of children and their aging caregivers.

Dysregulated CD40-NF-kappaB signaling in the pathophysiology of aggressive non -Hodgkin's lymphoma B cells

Non-Hodgkin's Lymphomas (NHL) are a group (>30) of important human lymphoid cancers that unlike other tumors today, are showing a marked increase in incidence. The lack of insight to the pathogenesis of B-cell NHL poses a significant problem in the early detection and effective treatment of these malignancies. This study shows that large B-cell lymphoma (LBCL) cells, the most common type of B-cell NHL (account for more than 30% of cases), have developed a novel mechanism for autonomous neoplastic B cell growth. We have identified that the key transcription factor NF-κB, is constitutively activated in LBCL cell lines and primary biopsy-derived LBCL cells, suggesting that they are autonomously activated, and do not require accessory T-cell signaling for cell growth and survival. Further studies have indicated that LBCL cells ectopically express an important T-cell associated co-mitogenic factor, CD154 (CD40 ligand), that is able to internally activate the CD401NF-κB pathway, through constitutive binding to its cognate receptor, CD40, on the lymphoma cell surface. CD40 activation triggers the formation of a “Signalosome” comprising virtually the entire canonical CD40/NF-κB signaling pathway that is anchored by CD40 in plasma membrane lipid rafts. The CD40 Signalosome is vulnerable to interdiction by antibody against CD40 that disrupts the Signalosome and induces cell death in the malignant cells. In addition to constitutive NF-κB activation, we have found that the nuclear factor of activated T cells (NFAT) transcription factor is also constitutively activated in LBCL cells. We have demonstrated that the constitutively active NFATc1 and c-rel members of the NFAT and NF-κB families of transcription factors, respectively, interact with each other, bind to the CD154 promoter, and synergistically activate CD154 gene transcription. Down-regulation of NFATc1 and c-rel with small interfering RNA inhibits CD154 gene transcription and lymphoma cell growth. Our findings suggest that continuous CD40 activation not only provides dysregulated proliferative stimuli for lymphoma cell growth and extended tumor cell survival, but also allows continuous regeneration of the CD40 ligand in the lymphoma cell and thereby recharges the system through a positive feedback mechanism. Targeting the CD40/NF-κB signaling pathway could provide potential therapeutic modalities for LBCL cells in the future. ^

End -of -life planning and decision -making: Implications for adults with mental retardation

This research focused on the topic of end-of-life planning and decision-making for adults affected by mental retardation. Adults with mental retardation have unique challenges in this regard, including difficulty communicating their wishes without assistance and diminished decision-making skills. The primary research objective was to identify factors that can affect opportunities for adults with mental retardation in community-based services settings (and their advocates) to be involved in planning and deciding about their own end-of-life experience. ^ A descriptive qualitative inquiry was designed to explore issues related to death and dying, and the notion of end-of-life planning, from the perspective of adults with mental retardation who receive publicly-funded community services ("clients") and family members of individuals who receive such services. Study participants were recruited from a single mental retardation service provider in a large urban setting (the "Agency"). Sixteen clients and 14 families of Agency clients took part. Client data collection was accomplished through face-to-face interviews, focus group meetings, and record reviews; family members were involved in a face-to-face interview only. ^ An initial coding scheme was developed based upon literature and policy reviews, and themes related to the research questions. Analysis involved extracting data from transcripts and records and placing it into appropriate thematic categories, building support for each theme with the accumulated data. Coding themes were modified to accommodate new data when it challenged existing themes. ^ Findings suggest that adults with mental retardation do have the requisite knowledge, interest, and ability to participate in decisions about their end-of-life experience and handling of affairs. Siblings are overwhelmingly the chosen future surrogates and they (or their children) will likely be the end-of-life advocates for their brothers and sisters affected by mental retardation. Findings further point to a need for increased awareness, accurate information, and improved communication about end-of-life issues, both in general and particular to adults affected by mental retardation. Also suggested by the findings is a need to focus on creating accommodations and adaptations that can best uncover a person's authentic views on life and death and related end-of-life preferences. Practical implications and suggestions for further research are also discussed. ^

Measurements of gastropods shell sizes from 23 fossil and extant long-lived lakes

Aim: To investigate shell size variation among gastropod faunas of fossil and recent long-lived European lakes and discuss potential underlying processes. Location: 23 long-lived lakes of the Miocene to Recent of Europe. Methods: Based on a dataset of 1412 species of both fossil and extant lacustrine gastropods, we assessed differences in shell size in terms of characteristics of the faunas (species richness, degree of endemism, differences in family composition) and the lakes (surface area, latitude and longitude of lake centroid, distance to closest neighbouring lake) using multiple and linear regression models. Because of a strong species-area relationship, we used resampling to determine whether any observed correlation is driven by that relationship. Results: The regression models indicated size range expansion rather than unidirectional increase or decrease as the dominant pattern of size evolution. The multiple regression models for size range and maximum and minimum size were statistically significant, while the model with mean size was not. Individual contributions and linear regressions indicated species richness and lake surface area as best predictors for size changes. Resampling analysis revealed no significant effects of species richness on the observed patterns. The correlations are comparable across families of different size classes, suggesting a general pattern. Main conclusions: Among the chosen variables, species richness and lake surface area are the most robust predictors of shell size in long-lived lake gastropods. Although the most outstanding and attractive examples for size evolution in lacustrine gastropods derive from lakes with extensive durations, shell size appears to be independent of the duration of the lake as well as longevity of a species. The analogue of long-lived lakes as 'evolutionary islands' does not hold for developments of shell size because different sets of parameters predict size changes.

Distribution of benthic abyssal gastropods in the Iberian Deep-Sea Basin (Table 2)

During the cruises 3 and 15 of R.V. "Meteor", representatives of 7 families of benthic abyssal gastropods were collected. The prevalent group was the Turridae; the Naticidae are represented by 2 species, the remaining families by a single species each. A survey of the frequency and distribution of the species within the study area is given. A systematic part deals with the individual species in detail, including notes on taxonomy, material and distribution. Concerning the composition of the abyssal gastropod fauna of the present material, Neogastropoda are 4 times as many as Archaeogastropoda and 6 times as many as Mesogastropoda and Opisthobranchia. 89 % of all specimens are Neogastropoda. Usually deep-sea organisms have a non-pelagic development, but many of the Iberian deep-sea Turrids have a planktotrophic protoconch, that means a long pelagic larval period. Among the 19 species, 2 are cosmopolitan, 9 show a transatlantic distribution and 8 are confined to East-Atlantic basins.

On the Closure of the Tame Automorphism Group of Affine Three-Space

We provide explicit families of tame automorphisms of the complex affine three-space which degenerate to wild automorphisms. This shows that the tame subgroup of the group of polynomial automorphisms of C3 is not closed, when the latter is seen as an infinite-dimensional algebraic group.

Infrastructure Development of Railway in Cambodia: A Long Term Strategy

Infrastructure development means for the making of living environment, transport and communications, disaster prevention and national land conservation, agriculture, forestry and fisheries, and energy production and supply. Transport infrastructure development in Cambodia involved with (1) road, (2) railway, (3) port, inland-water way and (4) aviation. All model of transport infrastructure have special different kinds of importance. Railway is different from other base important of railways are transport passengers and traffic freight especially transport for heavy goods in huge capacity and in long distance by safer and faster. Transport in Cambodia for traffic freight export import base from Thailand and other via Sisophon and Shihanoukvill port. Traffic is increasing rapidly during nowadays railway condition in adequate of demand required. This is why Railway is selected as the topic of this paper to prevent monopoly of road transport. This paper, does review about infrastructure development plan for Railway in Cambodia as a long term strategy by review and analysis forecast on the previous performance of Royal Railways of Cambodia (RRC) transport traffic involved with condition of infrastructure development of railway in Cambodia. And also review the plan of development RRC but just only detail a plan of rehabilitation that is immediately needed. Suggest some recommendation at the last part. As Cambodia is a member country of ASEAN and also Mekong sub-region. For make sure that transport networks work effectively with a progress of economic integration, we make clear what is important for infrastructure development of railway in Cambodia from the standpoint of the development plan of Mekong sub-region. This paper is organized by 4 sections. Section 1 review about Infrastructure Development of Railway in Cambodia (IDRC) Historical Background, Follow by Section 2 will review the Current Situation of IDRC and some analysis of transport performance from previous years, Then Section 3 review of the focusing on traffic transport of RRC in the future, Section 4 review Infrastructure Development of Railway in Cambodia Future plans in long term; at last conclusion and recommendation. In section 1 does review history background of RRC from the rail first begun. But why is needed to review? Because of history background is involved infrastructure development of RRC in present time. History background made big gaps constraint and obstacle for socioeconomic development and poverty reduction, also left Cambodia with tragedy and left developed behind. After that remain infrastructure development needs huge fund and long time for restoration, reconstruction, rehabilitation and development into new technology as most of world practice.

Performance of Scheduling Policies in Adversarial Networks with Non-synchronized Clocks

In this paper we generalize the Continuous Adversarial Queuing Theory (CAQT) model (Blesa et al. in MFCS, Lecture Notes in Computer Science, vol. 3618, pp. 144–155, 2005) by considering the possibility that the router clocks in the network are not synchronized. We name the new model Non Synchronized CAQT (NSCAQT). Clearly, this new extension to the model only affects those scheduling policies that use some form of timing. In a first approach we consider the case in which although not synchronized, all clocks run at the same speed, maintaining constant differences. In this case we show that all universally stable policies in CAQT that use the injection time and the remaining path to schedule packets remain universally stable. These policies include, for instance, Shortest in System (SIS) and Longest in System (LIS). Then, we study the case in which clock differences can vary over time, but the maximum difference is bounded. In this model we show the universal stability of two families of policies related to SIS and LIS respectively (the priority of a packet in these policies depends on the arrival time and a function of the path traversed). The bounds we obtain in this case depend on the maximum difference between clocks. This is a necessary requirement, since we also show that LIS is not universally stable in systems without bounded clock difference. We then present a new policy that we call Longest in Queues (LIQ), which gives priority to the packet that has been waiting the longest in edge queues. This policy is universally stable and, if clocks maintain constant differences, the bounds we prove do not depend on them. To finish, we provide with simulation results that compare the behavior of some of these policies in a network with stochastic injection of packets.

Multi-criteria selection of structural adhesives to bond ABS parts obtained by rapid prototyping

One of the most used methods in rapidprototyping is Fused Deposition Modeling (FDM), which provides components with a reasonable strength in plastic materials such as ABS and has a low environmental impact. However, the FDM process exhibits low levels of surface finishing, difficulty in getting complex and/or small geometries and low consistency in “slim” elements of the parts. Furthermore, “cantilever” elements need large material structures to be supported. The solution of these deficiencies requires a comprehensive review of the three-dimensional part design to enhance advantages and performances of FDM and reduce their constraints. As a key feature of this redesign a novel method of construction by assembling parts with structuraladhesive joints is proposed. These adhesive joints should be designed specifically to fit the plastic substrate and the FDM manufacturing technology. To achieve this, the most suitable structuraladhesiveselection is firstly required. Therefore, the present work analyzes five different families of adhesives (cyanoacrylate, polyurethane, epoxy, acrylic and silicone), and, by means of the application of technical multi-criteria decision analysis based on the analytic hierarchy process (AHP), to select the structuraladhesive that better conjugates mechanical benefits and adaptation to the FDM manufacturing process
