Influence Of Professional Learning Communities On K-8 Teacher Responsibilities, Kristen Lynn Martello Jan 2018

Influence Of Professional Learning Communities On K-8 Teacher Responsibilities, Kristen Lynn Martello

Walden Dissertations and Doctoral Studies

Professional learning communities (PLCs) were established in a local suburban school district in 2010; however, since their inception, the value of the program has not been determined. In a K-8 school district, a qualitative case study was conducted to determine the influence of PLCs on the 4 domains of teacher responsibilities: preparation, classroom environment, teaching, and professional duties. The conceptual framework was based on Bandura's social learning theory and Danielson's framework for teaching. The research questions focused on how teacher participation and the allotment of time in a PLC, and the structure of a PLC, influence teacher classroom responsibilities. Data …

Assessing Executive Functioning In Young Children With Autism Spectrum Disorder, Julie Johnson Miller Jan 2018

Assessing Executive Functioning In Young Children With Autism Spectrum Disorder, Julie Johnson Miller

Walden Dissertations and Doctoral Studies

This study examined the inconsistency within research surrounding the relationship between executive functioning skills and autism symptomology in those being assessed for autism in early childhood (e.g., 34 to 60 months of age). Inconsistencies in current research connecting autism symptomology and executive dysfunction affect the best practice of practitioners that assess for disabilities. This study aimed to identify correlations between autism symptomology and executive functioning skills and whether combining autism symptomology and executive functioning skills assessments provide a more reliable classification as autism or non-autism. The framework foundation drew upon research that determined connections between those suffering from traumatic brain …

A Case Study Of Overcrowding In A County Jail In The Southeast United States, Marquice Robinson Jan 2018

A Case Study Of Overcrowding In A County Jail In The Southeast United States, Marquice Robinson

Walden Dissertations and Doctoral Studies

For the past several decades, the county jail in a large metropolitan city in the southeast United States has been overcrowded, which has resulted in violence within the jail, excessive costs to the Sheriff's Office, and a requirement of Federal oversight of the jail from 2005 to 2015.

Armms As A Versatile Platform For Intracellular Delivery Of Macromolecules, Qiyu Wang, Jiujiu Yu, Tatenda Kadungure, Joseph Beyene, Hong Zhang, Quan Lu Jan 2018

Armms As A Versatile Platform For Intracellular Delivery Of Macromolecules, Qiyu Wang, Jiujiu Yu, Tatenda Kadungure, Joseph Beyene, Hong Zhang, Quan Lu

Department of Nutrition and Health Sciences: Faculty Publications

Majority of disease-modifying therapeutic targets are restricted to the intracellular space and are therefore not druggable using existing biologic modalities. The ability to efficiently deliver macromolecules inside target cells or tissues would greatly expand the current landscape of therapeutic targets for future generations of biologic drugs, but remains challenging. Here we report the use of extracellular vesicles, known as arrestin domain containing protein 1 [ARRDC1]-mediated microvesicles (ARMMs), for packaging and intracellular delivery of a myriad of macromolecules, including the tumor suppressor p53 protein, RNAs, and the genome-editing CRISPR-Cas9/guide RNA complex. We demonstrate selective recruitment of these macromolecules into ARMMs. When …

On Legitimacy In Impact Assessment: An Epistemologically-Based Conceptualisation, Alan Bond, Jenny Pope, Francois Retief, Angus Morrison-Saunders Jan 2018

On Legitimacy In Impact Assessment: An Epistemologically-Based Conceptualisation, Alan Bond, Jenny Pope, Francois Retief, Angus Morrison-Saunders

Research outputs 2014 to 2021

Impact assessment (IA) is carried out as an ex ante process to inform decision-making. It includes requirements for engagement with stakeholders (including the public) regarding actions proposed by a proponent. A key issue with the various stakeholders involved is the perceived legitimacy of the IA, which can have implications both for the reputation of the proponent, and the likelihood of conflict over the decision. But the understanding of legitimacy in the IA literature has changed over time in line with an ontological shift from positivism (that scientifically generated information leads to better informed decisions) to the post-positivist acknowledgement of the …

Evolution Or Revolution: Where Next For Impact Assessment?, Zsuzsa Banhalmi-Zakar, Claire Gronow, Lachlan Wilkinson, Bryan Jenkins, Jenny Pope, Geraldine Squires, Kathy Witt, Galina Williams, Jon Womersley Jan 2018

Evolution Or Revolution: Where Next For Impact Assessment?, Zsuzsa Banhalmi-Zakar, Claire Gronow, Lachlan Wilkinson, Bryan Jenkins, Jenny Pope, Geraldine Squires, Kathy Witt, Galina Williams, Jon Womersley

Research outputs 2014 to 2021

Impact assessment (IA) has become one of the most prevalent environmental policy instruments today. Its introduction under the National Environmental Policy Act (US) in 1969 was revolutionary. Perhaps it is not surprising, then, that such a widely used tool has received its share of criticism, including that it fails to meet some of its fundamental goals. Over the last fifty years, IA has broadened in scope and application and embraced new techniques. It has followed evolved, but has not changed fundamentally. We believe that IA must continue to change to meet the societal and environmental challenges of the 21st century. …

The Trans-Pacific Partnership Agreement And The Changing Face Of Free Trade Agreements: The Resultant Social, Political, And Economic Consequences, Joseph Heyliger Jan 2018

The Trans-Pacific Partnership Agreement And The Changing Face Of Free Trade Agreements: The Resultant Social, Political, And Economic Consequences, Joseph Heyliger

Walden Dissertations and Doctoral Studies

Little is known about the impact of nontrade issues on developing countries entering trade agreements. The Trans-Pacific Partnership Agreement (TPPA) represents an attempt to set high-standard trade rules for participating countries in the Asian-Pacific region that require the inclusion of wide-ranging nontrade issues in the TPPA. This general qualitative study explored the economic, social, and political consequences for developing countries by including nontrade issues in Free Trade Agreements (FTAs). The overarching research question addressed whether nontrade issues in FTAs detract developing countries from achieving their trade goals. This study was guided by the theory of comparative advantage propounded by Ricardo …

Effective Strategies For Managing The Outsourcing Of Information Technology, Marsha N. Hopwood Jan 2018

Effective Strategies For Managing The Outsourcing Of Information Technology, Marsha N. Hopwood

Walden Dissertations and Doctoral Studies

More than half of information technology (IT) outsourced projects fail, primarily due to a lack of effective management practices surrounding the outsourcing end-to-end process. Ineffective management of the IT outsourcing (ITO) process affects organizations in the form of higher than expected project costs, including greater vendor switching or reintegration costs, poor quality, and loss of profits. These effects indicate that some business leaders lack the strategies to effectively manage the ITO process. The purpose of this single-case study was to apply the transaction cost economics (TCE) theory to explore strategies 5 business professionals use to manage an ITO project in …

The Impropriety Of Punitive Damages In Mass Torts, James A. Henderson Jr. Jan 2018

The Impropriety Of Punitive Damages In Mass Torts, James A. Henderson Jr.

Georgia Law Review

Punitive damages have been around for centuries in classic
one-on-one tort actions and are here to stay. Mass torts, of
more recent origin, have matured to the point that this article
is comfortable referring to most of them as traditional.
Notwithstanding the legitimacy of both institutions when
employed separately, loud warning signals should sound
when, as with drinking and driving, they are combined.
Potentially destructive mixes of punitive damages and mass
torts have, unfortunately, been prevalent in traditional,fault-
based mass tort actions. The difficulties are mostly
administrative.Although punitive damages are conceptually
compatible with fault-based mass torts, courts administer
punitive awards …

Cumulative Finality, Bryan Lammon Jan 2018

Cumulative Finality, Bryan Lammon

Georgia Law Review

A proper notice of appeal is a necessary first step in
most federal appeals. But federal litigants sometimes
file their notice of appeal early, before district court
proceedings have ended. When those proceedingsfinally
end and no new notice is filed, the law of cumulative
finality determines what effect-if any-the premature
notice has. Sometimes the notice is effective and the
appeal proceeds as normal. Sometimes it's not, and
litigants lose their right to appeal.
At least, that's how the law of cumulative finality looks
from a distance. Up close, the courts of appeals are
hopelessly divided on matters of cumulative finality. …

The First Amendment Case Against Partisan Gerrymandering, Emmet J. Bondurant Ii, Ben W. Thorpe Jan 2018

The First Amendment Case Against Partisan Gerrymandering, Emmet J. Bondurant Ii, Ben W. Thorpe

Georgia Law Review

The Supreme Court recognizes that "[p]artisan
gerrymanders... [are incompatible] with democratic
principles."I This makes good sense. The fundamental
objective of redistrictingis to "establish 'fairand effective
representation for all citizens. '2 And partisan
gerrymandering-whichthe Supreme Court defines as
"drawing... district lines to subordinate adherents of
one political party and entrench a rival party in
power'--runs counter to that fundamental objective.
Nonetheless, the Supreme Court has yet to invalidate
a redistricting plan solely as an unconstitutional
partisan gerrymander. This Symposium issue of the
Georgia Law Review, however, comes at a crucial
moment in the Court's treatment of that question. A case
now …

Crowdfunding Signals, Darian M. Ibrahim Jan 2018

Crowdfunding Signals, Darian M. Ibrahim

Georgia Law Review

Entrepreneurs can now “crowdfund,” or sell securities to unaccredited investors over the Internet, to raise capital. But will these companies be able to attract the follow-on investors (angels and venture capitalists) that are necessary for long-term success? Angels and VCs face extreme levels of information asymmetry when deciding whether to fund a company. Signals can reduce this asymmetry. Early commentary argues a company only crowdfunds as a last resort for fear of sending a negative signal about the company’s quality to follow-on investors. This Article argues the inverse. This Article argues a successful crowdfunding campaign can send a positive signal …

If Established By Law, Then An Administrative Judge Is An Officer, Jennifer L. Cotton Jan 2018

If Established By Law, Then An Administrative Judge Is An Officer, Jennifer L. Cotton

Georgia Law Review

Administrative Judges (AJs) are a large and often overlooked group of federal agency adjudicators. While courts have examined Article II Appointments Clause challenges to Administrative Law Judges (ALJs), courts have yet to encounter a legal challenge to the constitutionality of AJs’ appointment procedures. The constitutionality of any federal government actor’s appointment is dependent upon whether that actor is an “officer” or an “employee” under the Article II Appointments clause. It is apparent that the current “significant authority” test that the Supreme Court has espoused to distinguish between officers and employees is unworkable. This Note endeavors to set forth a bright-line …

Thematic Narrative Of Lgbt Faculty Members' Professional Identity And Activism, Kathy Luanne Williamson Gall

Walden Dissertations and Doctoral Studies

Over the past 20 years, lesbian, gay, bisexual, and transgender (LGBT) individuals have made progress in attaining the same basic civil rights as heterosexual individuals. As in other civil rights movements, the college campus has played an important role.
