Warby Parker: A Blurred Vision of Profitability

Warby Parker is a rising competitor in the heavily consolidated eyewear industry. When it launched in 2008, the company took on a blue ocean strategy, which incorporates both cost leadership and product differentiation, in hopes of defeating powerful incumbents. Rather than selling its frames in existing eyewear retailers, many of which are owned by competitors, Warby Parker launched online, selling high-quality frames at an affordable price. More than a decade later, the company is reevaluating its strategy as it has yet to become profitable

Perspectives on Adoption from Christian Adoptive Parents: A Qualitative Study

Although adoption has long been studied, the rising current evangelical trend of adopting has brought about a new series of questions, mostly pertaining to, “What is it like to be a Christian adoptive parent?” The research goals were to understand how faith motivates one’s decision to adopt and the assimilation of the adopted child into the family, to examine the parallels between theological adoption and human experience adoption, and to see if parents have a qualitatively different kind of bonding or affection for their biological and adoptive children. This qualitative research study was conducted through semi-structured interviews with practicing Christians who have both biological and adopted children. Several major themes emerged from these qualitative interviews, some of which pertain to: the theological or spiritual reasons for adoption, a more concrete understand of theological constructs, the importance of names, and “adoption legacy.

ChemInform Abstract: Dynamic Kinetic Resolution of α-Keto Esters via Asymmetric Transfer Hydrogenation.

The dynamic kinetic resolution of β-aryl α-keto esters has been accomplished using a newly designed (arene)RuCl(monosulfonamide) transfer hydrogenation catalyst. This dynamic process generates three contiguous stereocenters with remarkable diastereoselectivity through a reduction/lactonization sequence. The resulting enantioenriched, densely functionalized γ-butyrolactones are of high synthetic utility, as highlighted by several secondary derivatizations

Persons with disabilities in Robeson County, North Carolina : an action-oriented community diagnosis : findings and next steps of action

The following document is a detailed report of an Action Oriented Community Diagnosis (AOCD) completed by a five-member team of graduate students at University of North Carolina at Chapel Hill, School of Public Health, Department of Health Behavior and Health Education. This AOCD was conducted in order to gain an understanding of the cultural, social, economic, and health experiences of persons with disabilities and their families in Robeson County, North Carolina. Through the AOCD process, the team and community participants identified resources, strengths, and challenges that exist in Robeson County for persons with disabilities and their families, and developed action steps to address several of the challenges. Over the course of seven months from October 2007 to April 2008, the team worked to learn more about the community. Through conducting secondary data, attending community events, and conducting 28 in-depth interviews with 20 service providers and eight community members and three focus groups with 13 community members, team members gained valuable insight into everyday life in this community. The team developed a coding system to analyze the data collected and to identify recurring themes related to living with disabilities in Robeson County. In April 2008, the team organized a community forum at the O.P. Owens Building in Lumberton, the county seat, to present findings from the AOCD process to over 43 community members and service providers. At the forum, participants had the opportunity to discuss major themes that emerged from the team‘s data analysis, and to work together in small groups to create specific action steps to address those themes. The themes and action steps discussed at the forum were: 1. Transportation: There is a lack of accessible, reliable, and affordable transportation options in Robeson County. This limits quality of life, access to services, and employment for people living with disabilities. Attend County Commissioner meetings. Attend Mayor‘s Committee for the Disabled meetings. Call SEATS to ask about safety procedures, weight limits, and wheelchair accessible vans. Research how other communities with similar demographics and geographies have addressed transportation for persons with disabilities. Look into recreating the voucher program. Create an education campaign for service providers, wheelchair vendors, persons with disabilities, and the general community about transportation issues faced by persons with disabilities. Talk to physicians and physical therapists about transportation issues faced by persons with disabilities, including how selection of wheelchair can affect opportunities for public transportation. 2. Services Communication and Information: Although many services exist for persons with disabilities in Robeson County, there is a lack of a centralized information system accessible to people with low literacy and without access to computer technology. There is also a lack of partnership between service providers. This causes confusion and limited knowledge about services for service providers, persons with disabilities and their families. Contacting the Healing Lodge in the county to facilitate a discussion with those members and connect them to disability resources. Service providers presenting at healthcare to educate the community about services available. Finding out more about the 211 telephone information service provided by United Way. Collaborate with other agencies on the Partnership for Community Health booklet by letting Partnership know about more providers. 3. Recreation: There is an interest among persons with disabilities to become physically active. There is a lack of recreational opportunities and facilities for persons with disabilities in Robeson County. This limits social and recreational interaction and creates barriers for physical fitness. Advertise and increase awareness of disabilities and recreational opportunities for persons with disabilities in the local newspapers. Form a support group for persons with disabilities to increase awareness of the need for recreation for persons with disabilities. Hold first meeting of support group where the ADA laws that ensure persons with disabilities access to accessible public recreational opportunities are explained. Organize monthly activities for persons with disabilities. 4. Awareness: There is limited awareness among community members and service providers about persons with disabilities, especially “invisible disabilities,” such as chronic illness and substance abuse. This contributes to feelings of isolation and disrespect that diminish the quality of life for persons with disabilities and caregivers. Train healthcare workers in disability awareness by having them use different assistance devices, such as wheelchairs, for a day. Be vocal as persons with disabilities and share experiences and perspectives with others. Advocate for disability awareness by integrating discussions of disability in other venues. Educate employers about ADA rights. 5. Paying for services: Although many people living with disabilities in Robeson County are supported by Medicaid, many others are uninsured and have difficulty paying for medical services. This causes people to delay seeking medical help and decreases the reach and effectiveness of existing resources. Action steps were not developed for this group as there were not enough attendees who participated in developing action steps around this theme. Following the forum, the team completed this final report with recommendations for the community based on their experiences throughout the process and the outcomes from the community forum. The final recommendations are summarized below: 1. Service providers for persons with disabilities in Robeson County should continue to update the resource list that the team has compiled and included in this document and should make it available in multiple formats designed for the those with vision loss, low literacy, and without access to computer technology. 2. Service providers for persons with disabilities in Robeson County should create a centralized referral system that could direct its users to different services, including medical and social services, as suggested by several service providers and community members. This could be started by further publicizing the existing 211 telephone directory. 3. Community members and service providers should advocate for the expansion of the county transit program (SEATS), including more accessible vans and drivers, affordable fares, and weekend routes. 4. Service providers should hold annual public events such as a community forum or health fair to increase awareness of disabilities and services and resources available to persons with disabilities in Robeson County. This can be hosted by a local health agency or an advocacy organization such as the Mayor‘s Committee for the Disabled. 5. Community members and service providers should advocate for the perspectives of persons with disabilities in public meetings about county development, including new and existing projects. Persons with disabilities and their supporters should be aware of local news, attend town, city or county meetings whenever possible, and share their views and ideas with the larger community. The Mayor‘s Committee for the Disabled should support persons with disabilities in these efforts by publicizing their meeting times and by helping persons with disabilities access schedules of other local government meetings and public hearings. The team hopes that this report, the action steps, community member and service provider connections, and the strong sense of initiative for change that emerged from this project and the community forum will continue to build on the strengths of this community. Ultimately, the team also hopes that the entire AOCD process and this final report contribute to future improvements not only for persons with disabilities, but for all residents of Robeson County.Master of Public Healt

Black Box Chimera Check (B2C2): a Windows-Based Software for Batch Depletion of Chimeras from Bacterial 16S rRNA Gene Datasets

The existing chimera detection programs are not specifically designed for "next generation" sequence data. Technologies like Roche 454 FLX and Titanium have been adapted over the past years especially with the introduction of bacterial tag-encoded FLX/Titanium amplicon pyrosequencing methodologies to produce over one million 250-600 bp 16S rRNA gene reads that need to be depleted of chimeras prior to downstream analysis. Meeting the needs of basic scientists who are venturing into high-throughput microbial diversity studies such as those based upon pyrosequencing and specifically providing a solution for Windows users, the B2C2 software is designed to be able to accept files containing large multi-FASTA formatted sequences and screen for possible chimeras in a high throughput fashion. The graphical user interface (GUI) is also able to batch process multiple files. When compared to popular chimera screening software the B2C2 performed as well or better while dramatically decreasing the amount of time required generating and screening results. Even average computer users are able to interact with the Windows .Net GUI-based application and define the stringency to which the analysis should be done. B2C2 may be downloaded from http://www.researchandtesting.com/B2C2

Miles to go (mtgo) encodes FNDC3 proteins that interact with the chaperonin subunit CCT3 and are required for NMJ branching and growth in Drosophila.

Analysis of mutants that affect formation and function of the Drosophila larval neuromuscular junction (NMJ) has provided valuable insight into genes required for neuronal branching and synaptic growth. We report that NMJ development in Drosophila requires both the Drosophila ortholog of FNDC3 genes; CG42389 (herein referred to as miles to go; mtgo), and CCT3, which encodes a chaperonin complex subunit. Loss of mtgo function causes late pupal lethality with most animals unable to escape the pupal case, while rare escapers exhibit an ataxic gait and reduced lifespan. NMJs in mtgo mutant larvae have dramatically reduced branching and growth and fewer synaptic boutons compared with control animals. Mutant larvae show normal locomotion but display an abnormal self-righting response and chemosensory deficits that suggest additional functions of mtgo within the nervous system. The pharate lethality in mtgo mutants can be rescued by both low-level pan- and neuronal-, but not muscle-specific expression of a mtgo transgene, supporting a neuronal-intrinsic requirement for mtgo in NMJ development. Mtgo encodes three similar proteins whose domain structure is most closely related to the vertebrate intracellular cytosolic membrane-anchored fibronectin type-III domain-containing protein 3 (FNDC3) protein family. Mtgo physically and genetically interacts with Drosophila CCT3, which encodes a subunit of the TRiC/CCT chaperonin complex required for maturation of actin, tubulin and other substrates. Drosophila larvae heterozygous for a mutation in CCT3 that reduces binding between CCT3 and MTGO also show abnormal NMJ development similar to that observed in mtgo null mutants. Hence, the intracellular FNDC3-ortholog MTGO and CCT3 can form a macromolecular complex, and are both required for NMJ development in Drosophila

Mesophilic and Thermophilic Conditions Select for Unique but Highly Parallel Microbial Communities to Perform Carboxylate Platform Biomass Conversion

The carboxylate platform is a flexible, cost-effective means of converting lignocellulosic materials into chemicals and liquid fuels. Although the platform's chemistry and engineering are well studied, relatively little is known about the mixed microbial communities underlying its conversion processes. In this study, we examined the metagenomes of two actively fermenting platform communities incubated under contrasting temperature conditions (mesophilic 40°C; thermophilic 55°C), but utilizing the same inoculum and lignocellulosic feedstock. Community composition segregated by temperature. The thermophilic community harbored genes affiliated with Clostridia, Bacilli, and a Thermoanaerobacterium sp, whereas the mesophilic community metagenome was composed of genes affiliated with other Clostridia and Bacilli, Bacteriodia, γ-Proteobacteria, and Actinobacteria. Although both communities were able to metabolize cellulosic materials and shared many core functions, significant differences were detected with respect to the abundances of multiple Pfams, COGs, and enzyme families. The mesophilic metagenome was enriched in genes related to the degradation of arabinose and other hemicellulose-derived oligosaccharides, and the production of valerate and caproate. In contrast, the thermophilic community was enriched in genes related to the uptake of cellobiose and the transfer of genetic material. Functions assigned to taxonomic bins indicated that multiple community members at either temperature had the potential to degrade cellulose, cellobiose, or xylose and produce acetate, ethanol, and propionate. The results of this study suggest that both metabolic flexibility and functional redundancy contribute to the platform's ability to process lignocellulosic substrates and are likely to provide a degree of stability to the platform's fermentation processes

Global chemical effects of the microbiome include new bile-acid conjugations

A mosaic of cross-phylum chemical interactions occurs between all metazoans and their microbiomes. A number of molecular families that are known to be produced by the microbiome have a marked effect on the balance between health and disease. Considering the diversity of the human microbiome (which numbers over 40,000 operational taxonomic units), the effect of the microbiome on the chemistry of an entire animal remains underexplored. Here we use mass spectrometry informatics and data visualization approaches to provide an assessment of the effects of the microbiome on the chemistry of an entire mammal by comparing metabolomics data from germ-free and specific-pathogen-free mice. We found that the microbiota affects the chemistry of all organs. This included the amino acid conjugations of host bile acids that were used to produce phenylalanocholic acid, tyrosocholic acid and leucocholic acid, which have not previously been characterized despite extensive research on bile-acid chemistry. These bile-acid conjugates were also found in humans, and were enriched in patients with inflammatory bowel disease or cystic fibrosis. These compounds agonized the farnesoid X receptor in vitro, and mice gavaged with the compounds showed reduced expression of bile-acid synthesis genes in vivo. Further studies are required to confirm whether these compounds have a physiological role in the host, and whether they contribute to gut diseases that are associated with microbiome dysbiosis
