description: Attempts to encourage and institutionalize citizen participation in planning are fraught with tensions between democratic participation and professional expertise; the reconciliation of local or group interests with larger, citywide interests; process versus outcome; and so on. Who participates, why, on whose terms, how, and with what consequences for themselves, their neighborhoods, the decision process, and outcomes, have been the subject of numerous studies. In this context, a distinction has emerged between mere citizen involvement in planning initiated by public agencies to grassroots and bottom-up planning that originates from within neighborhoods and citizen groups and whose decisions are adopted by public agencies. Through a case study based in Madison, Wisconsin, this paper identifies an institutional alternative that addresses some of the tensions related to community participation in planning and the problems associated with collaboration: a resident-nonprofit collaborative within a larger urban context facilitative of neighborhood planning. The paper provides a brief overview of the process, identifies lessons from this process for community participation and grassroots planning, and places this experience in the larger debates on participation. It discusses the value of resident-nonprofit collaboratives within the comparative framework of alternative forms of community participation. A concluding section discusses the implications of these findings for planning practice.

description: This paper discusses the relationship between transfer of laws from one country to another and legitimation of the law associated with the transfer. Drawing lessons from the legal transfer experience of Latin America in the 1960s, the paper attempts to ascertain what relevance, if any, legal transfer has in the context of the emerging market economies and democratic societies of the former communist countries of East Europe and the Soviet Union. It is argued that attempts at exporting laws have failed when little or no attempt is made to understand the processes of how law is legitimized within a specific country. The cultural orientation of a particular country or section of society at a particular point in time will determine how legal culture is formed and sustained and will thus affect the degree to which law is legitimized. Drawing on the theoretical discussions of section one, a short case study of law related to rural property rights in Albania is presented in section two.

description: The localization of the short-duration, hard-spectrum GRB 050509b was a watershed event. Thanks to the nearly immediate relay of the GRB position by Swift, we began imaging the GRB field 8 minutes after the burst and continued for the following 8 days. No convincing optical/infrared candidate afterglow or supernova was found for the object. We present a re-analysis of the XRT afterglow and find an absolute position that is ~4" to the west of the XRT position reported previously. Close to this position is a bright elliptical galaxy with redshift z=0.2248, about 1' from the center of a rich cluster of galaxies. Based on positional coincidences, the GRB and the bright elliptical are likely to be physically related. We thus have discovered evidence that at least some short-duration, hard-spectra GRBs arise at cosmological distances. However, while GRB 050509b was underluminous compared to long-duration GRBs, we demonstrate that the ratio of the blast-wave energy to the gamma-ray energy is consistent with that of long-duration GRBs. Based on this analysis, on the location of the GRB (40 +- 13 kpc from a bright galaxy), on the galaxy type (elliptical), and the lack of a coincident supernova, we suggest that there is now observational consistency with the hypothesis that short-hard bursts arise during the merger of a compact binary. We limit the properties of a Li-Paczynski ''mini-supernova.'' Other progenitor models are still viable, and additional rapidly localized bursts from the Swift mission will undoubtedly help to further clarify the progenitor picture. (abridged)

description: Semiconductor design companies are integrating proprietary intellectual property (IP) blocks to build custom integrated circuits (IC) and fabricate them in a third-party foundry. Unauthorized IC copies cost these companies billions of dollars annually. While several methods have been proposed for hardware IP obfuscation, they operate on the gate-level netlist, i.e., after the synthesis tools embed the semantic information into the netlist. We propose ASSURE to protect hardware IP modules operating on the register-transfer level (RTL) description. The RTL approach has three advantages: (i) it allows designers to obfuscate IP cores generated with many different methods (e.g., hardware generators, high-level synthesis tools, and pre-existing IPs). (ii) it obfuscates the semantics of an IC before logic synthesis; (iii) it does not require modifications to EDA flows. We perform a cost and security assessment of ASSURE.

description: In 1994, the United Nations introduced the concept of human security, predicating it on the dual notion of safety from chronic threats of hunger, disease, and repression on the one hand and protection from sudden and hurtful disruptions in daily life on the other. Such thinking helped foster the notion of "environmental refugee" to describe a new insight into an old phenomenon: large numbers of the world's least secure people seeking refuge from insecure biophysical environments. Yet, it can be misleading to assume that reducing environmental insecurity will avail more human security and, by extension, result in fewer environmental refugees. Under certain circumstances, more environmental security can generate a category of environmental refugees little noticed by those who have popularized this term. This paper concerns itself with the significant threat caused to human populations by exclusionary conservation. We begin by characterizing the human insecurity linked to increasing environmental security via protected area conservation, as a variant of environmental refugeeism. Using a combination of land use change and case study approaches, we estimate the number of Africans experiencing this phenomenon. We then place environmental refugeeism in the context of recent economic development theory and suggest why "environmental refugees" are in double jeopardy. That is, they often undergo a series of dislocations resulting from development initiatives, one form of which is protected area greenlining. We conclude with a discussion of one possible remedy for policy administrators seeking expanded conservation and a reduction in human displacement.

description: We introduce a skew analogue of the composition of the Cherednik and Drinfeld functors for twisted Yangians. Our definition is based on the skew Howe duality, and originates from the centralizer construction of twisted Yangians due to Olshanski. Using our functor, we establish a correspondence between intertwining operators on the tensor products of certain modules over twisted Yangians, and the extremal cocycle on the hyperoctahedral group.

description: Brassica incana Ten. (Brassicaceae) is an edible plant with very limited available information. Previous studies have demonstrated the polyphenolic profile and the antioxidant and cytotoxic properties of the leaf and flowering top hydroalcoholic extracts. The volatile composition and the antidiabetic and anti-obesity potential of B. incana leaf and flowering top extracts have been investigated. The volatile characterization of the extracts was attained by HS-SPME-GC/MS analysis. The antidiabetic and anti-obesity potential was investigated spectrophotometrically in vitro by the ability to modulate pancreatic lipase and α-glucosidase at different concentrations using orlistat and acarbose as reference drugs. The inhibition of advanced glycation end-products (AGEs) was measured with aminoguanidine as reference and the antioxidant activity with the xanthine/xanthine oxidase system and Trolox for comparative purposes. Several volatiles belonging to different chemical classes were identified, being sulphur compounds the most abundant in both leaf and flowering top extracts (56.33% and 64.40% of all volatiles). Although the leaf extract showed lower IC50 values in most of the assays (0.968 and 1.921 mg/mL for α-glucosidase; 0.192 and 0.262 mg/mL for AGEs; 0.022 and 0.038 mg/mL for superoxide scavenging), there were no statistically significant differences between both samples. These extracts showed a similar behaviour to Trolox in the xanthine oxidase assay (IC50 values of 0.022 mg/mL for leaf extract; 0.038 mg/mL for flowering top and 0.028 for Trolox). Leaves and flowering tops from B. incana can be used as sources of functional compounds that could act as antidiabetic and anti-obesogenic agents.

description: We have developed a new computer code, RAM, to solve the conservative equations of special relativistic hydrodynamics (SRHD) using adaptive mesh refinement (AMR) on parallel computers. We have implemented a characteristic-wise, finite difference, weighted essentially non-oscillatory (WENO) scheme using the full characteristic decomposition of the SRHD equations to achieve fifth-order accuracy in space. For time integration we use the method of lines with a third-order total variation diminishing (TVD) Runge-Kutta scheme. We have also implemented fourth and fifth order Runge-Kutta time integration schemes for comparison. The implementation of AMR and parallelization is based on the FLASH code. RAM is modular and includes the capability to easily swap hydrodynamics solvers, reconstruction methods and physics modules. In addition to WENO we have implemented a finite volume module with the piecewise parabolic method (PPM) for reconstruction and the modified Marquina approximate Riemann solver to work with TVD Runge-Kutta time integration. We examine the difficulty of accurately simulating shear flows in numerical relativistic hydrodynamics codes. We show that under-resolved simulations of simple test problems with transverse velocity components produce incorrect results and demonstrate the ability of RAM to correctly solve these problems. RAM has been tested in one, two and three dimensions and in Cartesian, cylindrical and spherical coordinates. We have demonstrated fifth-order accuracy for WENO in one and two dimensions and performed detailed comparison with other schemes for which we show significantly lower convergence rates. Extensive testing is presented demonstrating the ability of RAM to address challenging open questions in relativistic astrophysics.

Regulating hate propaganda in Japan : Canadian hate regulation and Japanese minorities
Creators: name: Yamamoto, Yōko
Publisher: name: University of British Columbia
Year: 2009

description: With the end of the Second World War, the importance of human rights protection and promotion became an important objective throughout much of the world. The incitement of hatred of members of minority groups, for instance, on the basis of race, religion or colour, is prohibited in many countries, including Canada. In addition to existing provisions in federal and provincial Human Rights Acts, Canada has criminalized hate propaganda by adding "Hate Propaganda" offences to its Criminal Code. However, such legal regulation has been controversial because of the possible conflict with freedom of expression. The purpose of this thesis is to analyze the rationales of anti-hate propaganda laws in Canada in light of the constitutional right to freedom of expression, and to ask whether similar laws should be introduced in Japan. Japan is a country often described as "homogeneous." Maintaining the reputation of being homogeneous in the racial and cultural context, Japan has avoided recognizing the existence of minorities. However, behind this illusion, minorities in Japan are hidden and forgotten. Members of minority groups quietly but certainly exist in Japan, fighting against racism and discrimination. Japanese minorities are also the targets of hateful expression. However, at present, Japanese law does not control discriminatory expression. The Canadian approach to hate propaganda expresses intolerance towards hate activities and promotes equality amongst people. With the rationales of the Canadian concept of anti-hate propaganda laws as a foundation for analysis, this thesis examines the possibility of regulating hate propaganda in Japan, based on the recognition of minority rights.

description: Property rights are social definitions; they exist as long as the society is willing to enforce them. If enforcement is missing, they cease to exist. The reasons for changes might be market conditions, popular sentiments, scientific knowledge, new technologies, lobbying, or legal battles. Biotechnologies are already having profound effects on how we organize property rights for natural resources. Resource rights change as our understandings and sentiments change. This paper presents a general overview of property rights in natural resources, with particular reference to water and land and emphasizing that rights are what a society is willing to grant and enforce. If companies, individuals, groups, or the state are not managing and stewarding resources in sustainable ways, their authority should be challenged. Rights are social inventions, and society can abrogate them.
A Closer Look at CP-Violating Higgs Portal Dark Matter as a Candidate for the GCE

description: A statistically significant excess of gamma rays has been reported and robustly confirmed in the Galactic Center over the past decade. Large local dark matter densities suggest that this Galactic Center Excess (GCE) may be attributable to new physics, and indeed it has been shown that this signal is well-modelled by annihilations dominantly into $b\bar{b}$ with a WIMP-scale cross section. In this paper, we consider Majorana dark matter annihilating through a Higgs portal as a candidate source for this signal, where a large CP-violation in the Higgs coupling may serve to severely suppress scattering rates. In particular, we explore the phenomenology of two minimal UV completions, a singlet-doublet model and a doublet-triplet model, and map out the available parameter space which can give a viable signal while respecting current experimental constraints.

description: This paper reports on research conducted for the Indigenous Land Corporation, an Australian government agency concerned with the acquisition and management of lands for indigenous peoples. The paper seeks to identify and analyze the kinds of institutional arrangements that might be deployed to support indigenous communities in the management of indigenous-owned land. It is concerned with a particular planning context in which the role of state agencies is focused on supporting and facilitating the work of indigenous landowners. This paper considers how best to arrange the institutional systems and processes of the nation state to support the management of indigenous lands management by their indigenous owners. To this end, the paper interrogates the utility of three models of planning: (1) institutional-regulatory, (2) community-based planning, and (3) reticulist, or facilitated process, approaches. The paper identifies the advantages and disadvantages of each of these approaches and argues for the development of a hybrid approach that integrates the positive features of all three models. The paper concludes that this hybrid model offers a set of institutional arrangements that enable collaborative planning between indigenous peoples and institutions of the state.

description: We present total and polarized intensity images of 15 active galactic nuclei obtained with the Very Long Baseline Array at 7 mm at 17 epochs from 1998 March to 2001 April. At some epochs the images are accompanied by nearly simultaneous polarization measurements at 3 mm, 1.35/0.85 mm, and optical wavelengths. Here we analyze the 7 mm images to define the properties of the jets of two radio galaxies, five BL Lac objects, and eight quasars on angular scales $\gtrsim 0.1$ milliarcseconds. We determine the apparent velocities of 106 features in the jets; for many of the features we derive Doppler factors using a new method based on comparison of timescale of decline in flux density with the light-travel time across the emitting region. This allows us to estimate the Lorentz factors, intrinsic brightness temperatures, and viewing angles of 73 superluminal knots, as well as the opening angle of the jet for each source. We analyze the derived physical parameters of the jets. In nine sources we detect statistically meaningful deviations from ballistic motion, with the majority of components accelerating with distance from the core. In six sources we identify jet features with characteristics of trailing shocks that form behind the primary strong perturbations in jet simulations. The apparent speeds of these components increase with distance from the core suggesting an acceleration of the underlying jet.

Subjects: subject: Education -- Research papers (Graduate)

description: No higher educational institution can aspire to become truly global without an active strategy to recruit, retain, and integrate the highest quality international students (Brustein, 2009). This study examines how one private liberal arts college in the mid-Atlantic area is serving the academic and co-curricular needs of its growing international student population. If the college that acts as the site for this research study is to uphold its commitment to creating globally aware and engaged students, it must consider whether it is doing enough to attract and integrate international students into the life of campus. International students not only inform other students about non-U.S. cultures in the classrooms and dorms, they also contribute significantly to a college or university’s financial viability. Through individual interviews, this study strives to elucidate these students’ perceptions of the academic and co-curricular support they receive at the college, their general perceptions of whether their needs are being met to satisfaction, and their level of engagement on the college’s campus. This study also recommends improvements so the study school can meet its potential to internationalize by serving the academic and co-curricular needs of its growing non-U.S. student population.

description: The purpose of this study was to determine if the number of referrals a middle school student
receives would change following a one-on-one student mentoring intervention (Check-In/Check- Out). The measurement tool was the number of minor and major discipline referrals as recorded by STARS. This study involved use of a pre-experimental design where one group of students received the intervention and data was examined before and after the intervention. Reductions in the number of minor referrals were significant for the students participating in the study. There was no significant change in the number of major referrals following the intervention. Research in this area should continue as school boards are looking for alternatives to suspension and the study showed signs of affecting behavior in a positive way.

description: The historical relationship between land use and population change among Wisconsin's Indian groups has been strikingly emblematic of the larger American Indian population. The ingredients of this rich relationship include the state's natural resource base, as well as the major engines of demographic change, namely fertility, mortality, and migration. In addition, federal policies have played a critical role in mediating this relationship. These policies have figured prominently since the earliest contact between Europeans and Wisconsin Indians and have continued to exert substantial influence. This paper discusses the past, present, and future relationship between the land and the state's Indian populations, paying particular attention to reservation populations. The reciprocal relationship between land and population among Wisconsin's Indians has evolved in an environment of changing social and political forces. Hence, the paper treats these issues in a chronological manner. It begins by reviewing the early period of contact between Europeans and Indians in the area known today as Wisconsin. Then, it discusses the creation of the state of Wisconsin and various Indian reservations, as well as their implications for Indian populations in the state. Next, it discusses federal land policies of the 19th and 20th centuries, and their effects on Wisconsin reservation populations. Finally, it describes current land tenure issues and the implications of future population growth.

description: Resistance to BCR-ABL tyrosine kinase inhibitor (TKI) is the cause of treatment failure in blast phase chronic myeloid leukaemia (BP-CML). Agents that act synergistically with BCR-ABL TKI are required to improve response. This work investigated the effects of stachydrine in CML. CML cells were treated with control or stachydrine at 20, 40 and 80 µM. Proliferation and apoptosis were examined after 72 h treatment. Combination studies were performed in four groups: control, TKI, stachydrine and the combination of stachydrine and TKI. Immunoblotting analysis was performed in CML cells after 24 h treatment. Stachydrine inhibited K562 (IC50 61 µM), KCL22 (IC50 141 µM), LAMA84 (IC50 86 µM), Ba/F3 T315I (IC50 26 µM), Ba/F3 WT (IC50 22 µM) and KU812 (IC50 35 µM) proliferation, and induced apoptosis in these CML cell lines. Stachydrine significantly induced apoptosis, inhibited colony formation and self-renewal in BP-CML CD34+ cells. The combination index of stachydrine and TKI combination was <1. Compared to TKI alone, the combination of stachydrine and TKI significantly induced more apoptosis and decreased colony formation in BP-CML CD34+ cells. Stachydrine decreased phosphorylation levels of multiple receptor tyrosine kinases in CML cells. Our study is the first to demonstrate (1) the anticancer activity of stachydrine on primary patient cancer cells; (2) the inhibitory effects of stachydrine on cancer stem cells; (3) the synergism between stachydrine and other anticancer drugs.

description: We consider a one-parameter family of third order nonlinear recurrence relations. Each member of this family satisfies the singularity confinement test, has a conserved quantity, and moreover has the Laurent property: all of the iterates are Laurent polynomials in the initial data. However, we show that these recurrences are not Diophantine integrable according to the definition proposed by Halburd. Explicit bounds on the asymptotic growth of the heights of iterates are obtained for a special choice of initial data. As a by-product of our analysis, infinitely many solutions are found for a certain family of Diophantine equations, studied by Mordell, that includes Markoff's equation.

Search for Low-Mass Leptoquarks using the $llqq$ final states in Pb-Pb Ultra-Peripheral Collisions

description: After a review over past experiments and theoretical requirements from low-energy flavour physics, we argue that the possibility of low-mass leptoquarks (LQ) cannot be fully excluded due to the assumptions made in the measurements. Therefore we propose to search for the pair production of low-mass leptoquarks in Pb-Pb ultra-peripheral collisions with the least model dependence (assuming a small coupling constant $\lesssim0.1$). There are a couple of advantages: 1) high photon flux provides high production rate for low mass LQs; 2) the background contamination is much lower than that in $p$-$p$ collisions. The analysis strategy permits a leptoquark to decay to all possible lepton-plus-quark modes. Taking the scalar LQ, $S_3$, with an electric charge $|q|=\frac{4}{3}e$, as example, the mass point of 100 GeV can be excluded at the 95~\% confidence level using a dataset of 4~pb$^{-1}$ Pb-Pb ultra-peripheral collisions at $\sqrt{s}=5.02$ TeV and the performance of the ATLAS detector in Run~2. The proposed method also applies to searching for high-mass LQs in $p$-$p$ collisions as long as the LQ pair production mechanism dominates.

description: This paper attempts to evaluate whether Albanian rural social structure has changed to the extent that individual rights and protection of those rights have become important policy questions. If the evaluation suggests that rural Albanians retain the set of family-oriented norms and beliefs that are based primarily on patriarchalism and patrilineal inheritance, we must address the following questions: How appropriate is the mixture of western law that emulates individualistic notions of property rights with the customary family-tenure system of rural Albania? What are the likely problems that could emerge during the transition given a potential conflict between family notions of ownership and individual notions of ownership? This paper discusses five broad issues: the contemporary importance of family ownership, the role of the patriarch, the contemporary inheritance procedures, the vulnerability of specific groups of women, and the structure of the Albanian family.

description: We report the results of identification of 8 hard X-ray sources discovered by the INTEGRAL observatory during the ongoing all-sky survey. These sources have been observed by Chandra. In 6 cases a bright X-ray source was found within the INTEGRAL localization region, which permitted to unambigously identify 5 of the objects with nearby galaxies, implying that they have an active galactic nucleus (AGN), whereas one source is likely an X-ray binary in LMC. 4 of the 5 newly discovered AGNs have measured redshifts in the range 0.025-0.055. The X-ray spectra reveal the presence of significant amounts of absorbing gas (NH in the range 10^22-10^24 cm^-2) in all 5 AGNs, demonstrating that INTEGRAL is starting to fill in the sample of nearby obscured AGNs.

description: The photoproduction of bottomonium-like states $Z_{b}(10610)$ and $Z_{b}(10650)$ via $γp$ scattering is studied within an effectiv Lagrangian approach and the vector-meson-dominance model. The Regge model is employed to calculate the photoproduction of $Z_{b}$ states via $t$-channel with $π$ exchange.The numerical results show that the values of the total cross-sections of $Z_{b}(10610)$ and $Z_{b}(10650)$ can reach 0.09 nb and 0.02 nb, respectively, near the center of mass energy of 22 GeV. The experimental measurements and studies on the photoproduction of $Z_{b}$ states near energy region around $W\simeq 22$ GeV is suggested. Moreover, with the help of eSTARlight and STARlight programs, one obtains the cross-sections and event numbers of $Z_{b}(10610)$ production in electron-ion collision (EIC) and Ultraperipheral collisions (UPCs). The results show that a considerable number of events from $Z_{b}(10610)$ can be produced on the relevant experiments of EICs and UPCs. Also, one calculates the rates and kinematic distributions for $γp\rightarrow Z_{b}n$ in $ep$ and $pA$ collisions via EICs and UPCs, and the relevant results will provide an important reference for the RHIC, LHC, EIC-US, LHeC, and FCC experiments to search for the bottomonium-like $Z_{b}$ states.

description: The U(1)' symmetry associated with a possible heavy Z' would have profound implications for particle physics and cosmology. The motivations for such particles in various extensions of the standard model, possible ranges for their masses and couplings, and classes of anomaly-free models are discussed. Present limits from electroweak and collider experiments are briefly surveyed, as are prospects for discovery and diagnostic study at future colliders. Implications of a Z' are discussed, including an extended Higgs sector, extended neutralino sector, and solution to the mu problem in supersymmetry; exotic fermions needed for anomaly cancellation; possible flavor changing neutral current effects; neutrino mass; possible Z' mediation of supersymmetry breaking; and cosmological implications for cold dark matter and electroweak baryogenesis.

description: Valerian extract capsule (VEC) is an effective Chinese patent medicine used for gastrointestinal (GI) diseases. To investigate the detailed pharmacological activity for VEC clinical effects in GI diseases. Sprague-Dawley rats were divided into six groups: control, model, and drug-treated (VEC-L, VEC-M, VEC-H, and teprenone). Rats were orally administered VEC (124, 248, 496 mg/kg) and teprenone (21.43 mg/kg) for 3 consecutive days. After 1 h, the five groups (except the control group) were orally given ethanol (10 mL/kg) for 1 h or indomethacin (80 mg/kg) for 7 h. The spasmolytic activity of VEC (0.01–1 mg/mL) on ACh/BaCl2-induced New Zealand rabbit smooth muscle contraction was performed. The C57BL/6 mice carbon propelling test evaluated the effects of VEC (248–992 mg/kg) on intestinal motility in normal and neostigmine/adrenaline-induced mice. Compared with the model group, VEC treatment reduced the gastric lesion index and mucosal damage. Further experiments showed that the pathological ameliorative effect of VEC was accompanied by augmentation of the enzymatic antioxidant system and cytoprotective marker (COX-1, p < 0.01; PGI2 p < 0.05;), along with the alleviation of the levels of MPO (ethanol: 15.56 ± 0.82 vs. 12.15 ± 2.60, p < 0.01; indomethacin: 9.65 ± 3.06 vs. 6.36 ± 2.43, p < 0.05), MDA (ethanol: 1.66 ± 0.44 vs. 0.81 ± 0.58, p < 0.01; indomethacin: 1.71 ± 0.87 vs. 1.09 ± 0.43, p < 0.05), and inflammatory mediators. VEC decreased the high tone induced by ACh/BaCl2 and promoted intestinal transit in normal and neostigmine/adrenaline-induced mice. VEC showed a potential gastroprotective effect, suggesting that VEC is a promising phytomedicine for the treatment of GI diseases.

Exact solitary wave solutions for a discrete $λϕ^4$ field theory in 1+1 dimensions

description: We have found exact, periodic, time-dependent solitary wave solutions of a discrete $ϕ^4$ field theory model. For finite lattices, depending on whether one is considering a repulsive or attractive case, the solutions are either Jacobi elliptic functions $\sn(x,m)$ (which reduce to the kink function $\tanh(x)$ for $m\to 1$), or they are $\dn(x,m)$ and $\cn(x,m)$ (which reduce to the pulse function $\sech(x)$ for $m\to 1$). We have studied the stability of these solutions numerically, and we find that our solutions are linearly stable in most cases. We show that this model is a Hamiltonian system, and that the effective Peierls-Nabarro barrier due to discreteness is zero not only for the two localized modes but even for all three periodic solutions. We also present results of numerical simulations of scattering of kink--anti-kink and pulse--anti-pulse solitary wave solutions.
The Effects of a Homework Club Intervention on Math Test Scores for At-Risk Second Graders in a Title I School
Creators: name: Francis, Shneequa

Subjects: subject: Education -- Research papers (Graduate)

description: The purpose of this quasi-experimental study, pretest-posttest design, was to determine the effects of supporting math homework completion on the math achievement grades of at-risk second graders in a Title I public school. Students, who were unsuccessful, scoring below 70%, were invited to participate in a homework club as an intervention, conducted by the researcher who was also the classroom teacher. The purpose of the homework club was to decrease students’ chances of becoming at-risk of failing the core subject. Five students were given permission by their parents to participate in the treatment after school homework club group and three students’ parents declined the invitations, the control group. Both groups were given the same measurements: the pretests and posttests from units one and two of the math curriculum, homework assignments, and surveys. Parents of both groups also completed a survey. Participants of the homework club received a modified survey at the end of the study to depict their perceptions about the homework club. Ratings from the surveys suggested that students enjoyed participating in the homework club because they were able to complete their homework assignments, receive help from the teacher, and self-select manipulatives to solve math problems. Additional results from this study indicate there was an increase in the number of math homework assignments completed and in academic achievement when comparing the differences of the pretest and posttest results for units one and two for both groups. However, participants in the homework club demonstrated more academic growth on their unit two math assessment. Further research should be conducted to explore the effects of a homework club as in intervention in other subject areas.

Subjects: subject: Education -- Research papers (Graduate)

description: The purpose of this study was to determine what effect the frequency of instruction has on students’ understanding of concepts and terminology in the physical education classroom, and whether frequency will affect student performance on standardized grade level assessments. The measurement tools used in the study were the Cooper Institute Fitnessgram assessment and a researcher-created grade level benchmark assessment. This was a causal-comparatives study. The study showed that increased frequency of instruction does affect student’s cognitive knowledge in the physical education classroom. Research in this area of instruction should continue to reinforce the importance of physical education and show the important effects of frequency of instruction in county school systems. Future studies should be done for a longer duration and performed with a larger sample size from diverse demographic areas.
