Classroom to Community: Bridging the Gap Between Health and Education
Creators: name: Falkovich, Anna
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Health and education are inextricably linked. Research shows that in the United States, children who are not motivated and unable to learn cannot achieve educational progress in school and later in life. Healthy kids attend more days of school, are more successful in the school setting, and achieve higher educational outcomes than their counterparts who struggle with health issues. The CDC developed a Coordinated School Health model and a Whole School, Whole Community, Whole Child approach to provide health services and physical and health education to students in schools. However, policy implementation across the country is not consistent, and many students are left without access to these critical components that will provide them with knowledge, skills, and tools to make healthy decisions. There remains a large gap between the health needs of our schools and students, and what is currently available to meet those needs. It is necessary to recognize and understand that the school environment is perhaps the most valuable resource we have: most kids spend the majority of their days in schools, or in school-related programming. Those in the academic and practice disciplines related to public health and education are beginning to understand that they can no longer work in siloes. To improve individual and community health outcomes, leaders must collaborate across sectors and work together to reach goals of healthier students in schools. A university with major resources, including a large volunteer base, has a unique opportunity to make a difference in the surrounding community and can address the large and increasing gaps in schools. Classroom to Community is an innovative and interdisciplinary approach to providing health education in the school setting by training health graduate students to prepare and deliver health lessons. Through a strong and collaborative partnership between Maureen Joy Charter School and Classroom to Community, graduate students at University of North Carolina at Chapel Hill gain the practical skills they desire, and public school students gain knowledge and skills in various health topics. C2C intervenes early, in elementary and middle school, so that students can make healthy decisions, engage in healthy behaviors, and become better learners in order to succeed today and tomorrow.

description: Due to its biocompatibility, electrical conductivity, and tissue-like elasticity, poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) constitutes a highly promising material regarding the fabrication of smart cell culture substrates. However, until now, high-throughput synthesis of pure PEDOT:PSS geometries was restricted to flat sheets and fibers. In this publication, the first microfluidic process for the synthesis of spherical, highly porous, pure PEDOT:PSS particles of adjustable material properties is presented. The particles are synthesized by the generation of PEDOT:PSS emulsion droplets within a 1-octanol continuous phase and their subsequent coagulation and partial crystallization in an isopropanol (IPA)/sulfuric acid (SA) bath. The process allows to tailor central particle characteristics such as crystallinity, particle diameter, pore size as well as electrochemical and mechanical properties by simply adjusting the IPA:SA ratio during droplet coagulation. To demonstrate the applicability of PEDOT:PSS particles as potential cell culture substrate, cultivations of L929 mouse fibroblast cells and MRC-5 human fibroblast cells are conducted. Both cell lines present exponential growth on PEDOT:PSS particles and reach confluency with cell viabilities above 95 vol.% on culture day 9. Single cell analysis could moreover reveal that mechanotransduction and cell infiltration can be controlled by the adjustment of particle crystallinity.
First-principles embedded-cluster calculations of the neutral and charged oxygen vacancy at the rutile TiO$_2$(110) surface

description: We perform full-potential screened-hybrid density-functional theory (DFT) calculations to compare the thermodynamic stability of neutral and charged states of the surface oxygen vacancy at the rutile TiO$_2$(110) surface. Solid-state (QM/MM) embedded-cluster calculations are employed to account for the strong TiO$_2$ polarization response to the charged defect states. Similar to the situation for the bulk O vacancy, the +2 charge state $V_{\rm O}^{2+}$ is found to be energetically by far most stable. Only for Fermi-level positions very close to the conduction band, small polarons may at best be trapped by the charged vacancy. The large decrease of the $V_{\rm O}^{2+}$ formation energy with decreasing Fermi-level position indicates strongly enhanced surface O vacancy concentrations for $p$-doped samples.

description: Self-shaping and actuating materials inspired by biological system have enormous potential for biosensor, microrobotics, and optics. However, the control of 3D-complex microactuation is still challenging due to the difficulty in design of nonuniform internal stress of micro/nanostructures. Here, we develop in-gel direct laser writing (in-gel DLW) procedure offering a high resolution inscription whereby the two materials, resin and hydrogel, are interpenetrated on a scale smaller than the wavelength of the light. The 3D position and mechanical properties of the inscribed structures could be tailored to a resolution better than 100 nm over a wide density range. These provide an unparalleled means of inscribing a freely suspended microstructures of a second material like a skeleton into the hydrogel body and also to direct isotropic volume changes to bending and distortion motions. In the combination with a thermosensitive hydrogel rather small temperature variations could actuate large amplitude motions. This generates complex modes of motion through the rational engineering of the stresses present in the multicomponent material. More sophisticated folding design would realize a multiple, programmable actuation of soft materials. This method inspired by biological system may offer the possibility for functional soft materials capable of biomimetic actuation and photonic crystal application.

Creators: name: Huang, Jui-Yen
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2012

description: Objectives. This study examined the relationship between demographic and contextual factors and global life satisfaction among Asian American adolescents. Methods. Data are derived from the Wave 1 National Longitudinal Study of Adolescent Health (Add Health), which is a nationally representative sample of adolescents in grade 7 through 12 during 1994-1995. Results. Better self-esteem (p<0.001) and perceived support from peers (p<0.01) were significantly associated with higher life satisfaction after controlling for other factors. Conclusions. Peer support and adolescents’ self-concept are strongly correlated with Asian American adolescents’ subjective well-being. To promote the wellness of this population, culturally sensitive strategies in developing peer relationship and healthy self-concept may be effective. More studies are needed for subgroup difference of various ethnicities among Asian American adolescents.
An Appraisal of the Legal Bottom-Line of Corporate Environmental Responsibility in Ethiopia

Year: 2023

description: While working towards attracting huge investment and promoting business whether or not developing countries have the necessary environmental legal regime to hold corporations legally liable is often an issue. In an effort to partly respond on the issue, this article is meant to assess the minimum environmental law requirements applied for holding business entities (both foreign and domestic) liable to their environmental misdemeanors in Ethiopia-‘the legal bottom lines of corporate environmental responsibility.’ The legal bottom lines of corporate environmental responsibility are requirements that corporations or business organizations are legally mandated to comply with. The purpose of this article is therefore to ascertain whether Ethiopia has the necessary environmental and related legal foundational frameworks to holding corporations accountable- determining the minimum legal framework. For this purpose doctrinal analyses were preferred as a method and assessment was made on relevant laws. Accordingly, the assessment finds that Ethiopia has foundational environmental legal regime and if applied may hold corporations liable. It further unearths that still the laws lack clarity; comprehensiveness and adequacy to flatteringly control businesses conduct to the contemporary requirements. Hence for a proper corporate environmental regulation, further amendment need to be made.

description: In this paper, we investigate the coexistence of two technologies that have been put forward for the fifth generation (5G) of cellular networks, namely, network-assisted device-to-device (D2D) communications and massive MIMO (multiple-input multiple-output). Potential benefits of both technologies are known individually, but the tradeoffs resulting from their coexistence have not been adequately addressed. To this end, we assume that D2D users reuse the downlink resources of cellular networks in an underlay fashion. In addition, multiple antennas at the BS are used in order to obtain precoding gains and simultaneously support multiple cellular users using multiuser or massive MIMO technique. Two metrics are considered, namely the average sum rate (ASR) and energy efficiency (EE). We derive tractable and directly computable expressions and study the tradeoffs between the ASR and EE as functions of the number of BS antennas, the number of cellular users and the density of D2D users within a given coverage area. Our results show that both the ASR and EE behave differently in scenarios with low and high density of D2D users, and that coexistence of underlay D2D communications and massive MIMO is mainly beneficial in low densities of D2D users.

description: DNA is more than a carrier of genetic information: It is a highly versatile structural motif for the assembly of nanostructures, giving rise to a wide range of functionalities. In this regard, the structure programmability is the main advantage of DNA over peptides, proteins, and small molecules. DNA amphiphiles, in which DNA is covalently bound to synthetic hydrophobic moieties, allow interactions of DNA nanostructures with artificial lipid bilayers and cell membranes. These structures have seen rapid growth with great potential for medical applications. In this Review, the current state of the art of the synthesis of DNA amphiphiles and their assembly into nanostructures are first summarized. Next, an overview on the interaction of these DNA amphiphiles with membranes is provided, detailing on the driving forces and the stability of the interaction. Moreover, the interaction with cell surfaces in respect to therapeutics, biological sensing, and cell membrane engineering is highlighted. Finally, the challenges and an outlook on this promising class of DNA hybrid materials are discussed.
Pluripotency, differentiation, and reprogramming: A gene expression dynamics model with epigenetic feedback regulation

description: Characterization of pluripotent states, in which cells can both self-renew and differentiate, and the irreversible loss of pluripotency are important research areas in developmental biology. In particular, an understanding of these processes is essential to the reprogramming of cells for biomedical applications, i.e., the experimental recovery of pluripotency in differentiated cells. Based on recent advances in dynamical-systems theory for gene expression, we propose a gene-regulatory-network model consisting of several pluripotent and differentiation genes. Our results show that cellular-state transition to differentiated cell types occurs as the number of cells increases, beginning with the pluripotent state and oscillatory expression of pluripotent genes. Cell-cell signaling mediates the differentiation process with robustness to noise, while epigenetic modifications affecting gene expression dynamics fix the cellular state. These modifications ensure the cellular state to be protected against external perturbation, but they also work as an epigenetic barrier to recovery of pluripotency. We show that overexpression of several genes leads to the reprogramming of cells, consistent with the methods for establishing induced pluripotent stem cells. Our model, which involves the inter-relationship between gene expression dynamics and epigenetic modifications, improves our basic understanding of cell differentiation and reprogramming.
Cyberspace, Surveillance, Law and Privacy

Year: 2017

description: The thesis titled, Cyberspace, Surveillance, Law and Privacy analyses the implications of state sponsored cyber surveillance on the exercise of the human right to privacy of communications and data privacy of individuals, subject to untargeted interception of digital communications. The principle aim of the thesis is to assess the legality of mass cyber surveillance of the Five Eyes alliance, with an emphasis on the United States and the United Kingdom. The study also considers the growing trend among the law enforcement agencies to access data without consent located in foreign jurisdictions without recourse to the Mutual Legal Assistance arrangements. The objective of the thesis is to demonstrate that these activities breach states’ human rights obligations under the international human rights frameworks and to show the unprecedented impact that surveillance technologies continue to have on this right. The research also highlights the inadequate protection of privacy in the internet. This leads to the evaluation of a number of possible legal solutions on the international level to the problem of mass surveillance, since the internet is a global environment designed for unrestricted data flows among jurisdictions and therefore facilitates continued violation of privacy of communications and data privacy. The thesis finds that bearing in mind (a) the highly politicised nature of the internet governance discourse, (b) the reluctance of states to subject peacetime espionage to international law regulation through a legally binding treaty, (c) the fact that international human rights law relating to privacy of communications is in need of modernization, (d) the reluctance of states to commit to a legally binding cyber treaty, (e) the slow pace with which customary cyber international law rules emerge and (f) the tendencies of states on the domestic level towards the introduction of draconian surveillance legislation at the expense of privacy, any progress in this regard at this stage will be piecemeal and likely to be achieved through a combination of the updating of the existing international and regional human rights and data protection instruments and soft law agreements.

Review of the use of the Ponseti method in treatment of neglected, recurrent or incomplete clubfoot
Creators: name: Barrows, Emily
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: This review was conducted in September of 2014 to research existing literature for the efficacy of the Ponseti method for treating clubfoot in children 2 years of age and older. Selection required that the study population have a mean age of greater than or equal to 24 months, that participants were diagnosed with congenital, idiopathic clubfoot and were treated using the Ponseti method. Nine research reports met inclusion criteria with mean patient ages ranging from 2-9 years. From these reports, correction of idiopathic clubfoot with the Ponseti method was achieved for the majority of patients in all studies. Based upon the most recent literature, the Ponseti method is effective in correcting idiopathic congenital clubfoot in older children.

We show that all these Bol loops are isotopic to direct products of Bruck loops of hyperbolic type or to Scheerer extensions of Lie groups by Bruck loops of hyperbolic type.
The Duty to Notify Planned Measures under International Watercourse Law and the Nile Basin Cooperative Framework Agreement
Creators: name: Bashahider, Zewdu Mengesha
Publisher: name: Bahir Dar University Journal of Law
Year: 2023

description: The duty to notify planned measures is one of the obligations imposed upon riparian states planning to perform activities that may have a significant adverse effect upon other watercourse states. Although the duty is found in the UN Watercourse Convention and other watercourse agreements, there is no consensus as to the details of this rule and its status under international watercourse law. Among the main points of contention are whether this obligation is a customary international law obligation and whether its non-observance would lead to the strict liability of the state concerned. Taking into account the divergent approaches of articulation of this duty under the UN Watercourse Convention and the Cooperative Framework Agreement over the Nile, there exist disagreements as to the contents of this duty. This has its own impact on the proper implementation of this duty by watercourse states. In this article the writer will mainly investigate the essence and normative basis of the duty to inform planned measures as enshrined under these instruments. The writer will mainly employ a doctrinal analysis in addressing the abovementioned issues and bases the scrutiny on the relevant sources of international law.

description: Nanoporous amorphous carbon constitutes a highly relevant material for a multitude of applications ranging from energy to environmental and biomedical systems. In the present work, it is demonstrated experimentally how energetic ions can be utilized to tailor porosity of thin sputter deposited amorphous carbon films. The physical mechanisms underlying self-organized nanoporous morphogenesis are unraveled by employing extensive molecular dynamics and phase field models across different length scales. It is demonstrated that pore formation is a defect induced phenomenon, in which vacancies cluster in a spinodal decomposition type of self-organization process, while interstitials are absorbed by the amorphous matrix, leading to additional volume increase and radiation induced viscous flow. The proposed modeling framework is capable to reproduce and predict the experimental observations from first principles and thus opens the venue for computer assisted design of nanoporous frameworks.

description: To search for optical variability on a wide range of timescales, we have carried out photometric monitoring of two flat spectrum radio quasars, 3C 454.3 and 3C 279, plus one BL Lac, S5 0716+714, all of which have been exhibiting remarkably high activity and pronounced variability at all wavelengths. CCD magnitudes in B, V, R and I pass-bands were determined for $\sim$ 7000 new optical observations from 114 nights made during 2011 - 2014, with an average length of $\sim$ 4 h each, at seven optical telescopes: four in Bulgaria, one in Greece, and two in India. We measured multiband optical flux and colour variations on diverse timescales. Discrete correlation functions were computed among B, V, R, and I observations, to search for any time delays. We found weak correlations in some cases with no significant time lags. The structure function method was used to estimate any characteristic time-scales of variability. We also investigated the spectral energy distribution of the three blazars using B, V, R, I, J and K pass-band data. We found that the sources almost always follows a bluer-when-brighter trend. We discuss possible physical causes of the observed spectral variability.

description: Dental implants can fail due to various factors, in which bad tissue integration is believed to have a significant role. Specific properties of the implant surface, such as its chemistry and roughness, are of paramount importance to address specific cell responses, such as the adsorption of proteins, as well as the adhesion and differentiation of cells, which are suitable for biomaterial and tissue engineering. In this study, an acrylate-containing coating was produced on titanium surfaces through the atmospheric pressure plasma treatment of a liquid precursor, 2-hydroxyethyl methacrylate. A hydrophilic coating was obtained, showing retention of the monomer chemistry as assessed by FTIR analysis and XPS. Enhanced fibroblast adhesion and decreased Staphylococcus aureus and Escherichia coli adhesion were recorded, showing that this is a suitable method to produce biocompatible coatings with a reduced bacterial adhesion.

description: The tracer gas method is one of the common ways to evaluate the air exchange rate in a naturally ventilated barn. One crucial condition for the accuracy of the method is that both considered gases (pollutant and tracer) are perfectly mixed at the points where the measurements are done. In the present study, by means of computational fluids dynamics (CFD), the mixing ratio NH3/CO2 is evaluated inside a barn in order to assess under which flow conditions the common height recommendation guidelines for sampling points (sampling line and sampling net) of the tracer gas method are most valuable. Our CFD model considered a barn with a rectangular layout and four animal-occupied zones modeled as a porous medium representing pressure drop and heat entry from lying and standing cows. We studied three inflow angles and six combinations of air inlet wind speed and temperatures gradients covering the three types of convection, i.e., natural, mixed, and forced. Our results showed that few cases corresponded to a nearly perfect gas mixing ratio at the currently common recommendation of at least a 3 m measurement height, while the best height in fact lied between 1.5 m and 2.5 m for most cases.

description: Since 1987, when the Brundtland Commission published its famous report, Our Common Future, discussions of urban and regional planning have tended to be strongly influenced by notions of 'sustainable development. ' This certainly is a welcome occurrence, but it is often forgotten that there is a far older tradition of visionary regional planning that anticipated many of the ideas of 'sustainable development.' While there is insufficient space here to treat their ideas in depth, a brief summary is offered in chronological order. In order to make the discussion more concrete, certain of these ideas are applied to the current situation in the Greater Vancouver region.

description: Artificial intelligence can be a game changer to address the global challenge of humanity-threatening climate change by fostering sustainable development. Since chemical research and development lay the foundation for innovative products and solutions, this study presents a novel chemical research and development process backed with artificial intelligence and guiding ethical principles to account for both process- and outcome-related sustainability. Particularly in ethically salient contexts, ethical principles have to accompany research and development powered by artificial intelligence to promote social and environmental good and sustainability (beneficence) while preventing any harm (non-maleficence) for all stakeholders (i.e., companies, individuals, society at large) affected.

description: The energy eigenvalues of a Dirac particle for the hyperbolic-type potential field have been computed approximately. It is obtained a transcendental function of energy, $\mathcal{F}(E)$, by writing in terms of confluent Heun functions. The numerical values of energy are then obtained by fixing the zeros on "$E$-axis" for both complex functions $Re[\mathcal{F}(E)]$ and $Im[\mathcal{F}(E)]$.

L.O.C.A.L: Ladies of Color Association for Lactation: A Grant Proposal to Improve Resources Available for Breastfeeding Women of Color in Cumberland County North Carolina
Creators: name: Williams, Zakiyah
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Breastfeeding is associated with a number of benefits for both mothers and infants including decreased risk of infections and increased overall health. African Americans have the lowest breastfeeding rates not only in North Carolina, but in the United States as a whole. They also have the highest rate of infant mortality. In an effort to improve the health of this population through this grant proposal, L.O.C.A.L. is seeking to provide 3 initiatives to support African American women with breastfeeding including the creation of community partnerships, implementation of peer support groups and an initiative to increase the diversity of the International Board Certified Lactation Consultants in the state.

description: This registration is to document the scoping document for the systematic review of the literature being conducted by RTI International as part of the HEAL Prevention Coordinating Center activities (supported by NIDA 1U24DA050182-01). Key Questions to Be Systematically Reviewed 1. What are the associations between suicide-related outcomes (death by suicide, suicide attempt, suicidal ideation) and opioid misuse or opioid use disorder (OUD) among adolescents (12 to 17, secondary school students) and young adults (18 to 30)? a. Review will include qualitative evaluation of the significance of associations and directionality when possible b. Review will include assessment of the role of internalizing (i.e., anxiety, depression) or externalizing (i.e., impulsivity, aggression) symptoms when possible 2. Do the associations between suicide-related outcomes and opioid misuse/OUD vary by individual characteristics such as age group (adolescent vs. young adult), race/ethnicity, gender identity, sexual orientation, and socioeconomic status? 3. Do the associations between suicide-related outcomes and opioid misuse/OUD vary across settings (e.g., by country, rural vs. urban, healthcare settings (such as primary/adolescent/pediatric care and behavioral health, school-based health centers), juvenile justice settings, and child welfare)?
Legal and Practical Aspects of Divorce, Compensation and Liquidation of Pecuniary Relation between Spouses
Creators: name: Afesha, Nigussie

description: Family is the natural and fundamental unit of a society. Marriage is one of the essential ways to form a family and it is usually concluded with the assumption that it will last a lifetime. However, in reality, many marital relations end up with divorce. The legal process of divorce, at a minimum, involves filing of petition and making financial arrangements. This article examines the practices of courts regarding divorce, compensation and liquidation of property with specific reference to courts in the Southern Nations, Nationalities and Peoples’ Regional State (SNNPRS) of Ethiopia. To this end, a qualitative research approach has been undertaken using case review, observation, and literature and legislative reviews methods. The overall tendency observed in the courts is that the rules governing divorce, liquidation of property and determination of compensation are not consistently applied. Most of the courts have developed their own definition of what constitutes fault and how they assess the amount of compensation.
 There is a wrong association between faults and modes of compensation and inconsistency in assessing the extent of the damage and its equivalent compensation that ranges from 52% to 66% of the common property for the same kind of fault. Such variations also existed in the process of liquidation of property. There are problems in identifying a personal and common property. In one case, the court makes the income obtained during the marriage a personal property, and in another case, the court decided a property, which is given to one of the spouses by donation as a common property of the spouses. In a few cases, the court decided that property, which belongs to a third party, as the common property of the spouses. In a different case, the court pends division of common property arguing that such properties are useful for the upbringing of children. Most decisions of the courts lack precision, which in turn expose the spouses for further litigation.

description: Linear algebra routines are basic building blocks for the statistical software. In this paper we analyzed how can we can improve R performance for matrix computations. We benchmarked few matrix operations using the standard linear algebra libraries included in the R distribution and high performance libraries like OpenBLAS, GotoBLAS and MKL. Our tests showed the the best results are obtained with the MKL library, the other two libraries having similar performances, but lower than MKL
Centralism, de-centralism and bio-regionalism

subject: Socialism and society

description: Two of the most important social movements in Canada today are the radical and social-democratic Left (exemplified by the Action Canada Network), and the environmental movement - in one of its more radical manifestations, as bioregionalism. At its best, the environmental movement is very concerned about the threat to sustainability posed by the growing power of the global economy and corporate capital. The Left, for its part, is coming to recognize the importance of the global ecological crisis. Together, these two movements have common goals. Both would like to limit or even eliminate capitalism and, for the most part, both would like to see a world in which ordinary Canadians had a lot more power. These similarities notwithstanding, they differ in their evaluation of what's needed and in their beliefs about what we should do to achieve a just, sustainable way of life.

description: Sharia can be defined as a divinely inspired legal system that exists within the religious
of framework of Islam. Sharia represents two distinct but directly related sets of laws.
The first segment consists of theories, principles, and objectives that serve as
foundations for the promulgation and interpretation of specific laws. There is an
independent discipline devoted to the study of philosophical and juristic principles of
Sharia law known as Principles of Islamic Jurisprudence (Usul al-Fiqh). The other part
of Sharia is concerned with the regulation and guidance of every day interaction of
individuals and society. This part of Sharia espouses detail legal rulings on the worldly
matters (Mua'malat) on one hand and set of rules governing ritual matters (Ibadat) on
the other. The Mua'malat laws have the objectives of realizing personal and public
benefit, ensure peace and wellbeing and prevention of harm and corruption in a
society. Sharia has all important attributes of rationality, gradualness and adaptability
that are essential for effective governance of human relationships at all times and
circumstances.
