Evaluation of the 57mFe Quadrupole Moment from Hartree-Fock Calculations
Authors: Hagelberg F. , Das T. P.
Published: February 2015

Two theoretical evaluations of 57mFe quadrupole moment (Q), based on different formalisms, namely the Hartree-Fock theory and the Linearized Augmented Plane Wave method have yielded results differing by a factor of two. In both cases, Q was obtained from experimental quadrupole interaction frequencies through investigation of the Electric Field Gradients at the nuclear site of the 57mFe probe. It is the purpose of the present work to reexamine the earlier Hartree-Fock approach. In particular, the earlier model is extended through a more realistic description of the environment of 57mFe in the respective experiments, as well as through inclusion of electron correlation effects.
Ab initio Study of Nitrogen-14 Nuclear Quadrupole Coupling and NMR Signal Linewidths in Some Azoles
Authors: Jaszuński Michał , Rizzo Antonio
Published: February 2015

Ab initio values of Nitrogen 14N Nuclear Quadrupole Coupling Constants (NQCC's) are calculated for a series of methyl-substituted azoles in the Multiconfigurational SCF (MCSCF) approximation. The four triazoles and two tetrazoles studied here are all isoelectronic. This enabled us to use the same level of approximation - basis set and active space -for all the molecules. The computed NQCC's are used to estimate the relative widths of the 14N NMR signals, assuming an identical effect of molecular tumbling for all the nuclei in a molecule and neglecting solvent effects. The linewidths for the unsubstituted N atoms are, in agreement with experiment, much larger than for the methyl-substituted N atom. For the 1-methyl-tetrazole we present also the NMR shielding and spin-spin coupling constants and discuss in some more detail the dependence of all calculated NMR properties on the basis set and correlation effects.
Ab initio Calculations of Electric Field Gradients for Transition Metal Impurities in TiO2
Authors: Sato K. , Akai H. , Minamisono T.
Published: February 2015

We present ab initio calculations of EFGs at impurities in a TiO2 crystal. They are directly calculated from the self consistent charge distribution which is determined by the KKR method within the muffin-tin approximation and based on the local density approximation. Impurities in the crystal are simulated by the super-cell method. Considering the charge state of Sc, Ti, Nb, Cd, Ta impurities in the TiO2 , the experimental values were well reproduced. The electronic structure of these impurities is discussed by analyzing the calculated density of states.
Dynamics of Liquid Crystals by Means of 2 H-NMR: a Comparison between 4,4'-bis(hexyloxy)azoxybenzene and the Derivative Pd(II) Complex AZPAC
Authors: Calucci Lucia , Forte Claudia , Geppi Marco , Veracini Carlo Alberto
Published: February 2015

In the present work we report a molecular dynamics investigation of the two mesogens 4,4'-bis(hexyloxy)azoxybenzene (HL) and its Pd(II) acetylacetonate derivative Azpac in their nematic phases. Deuterium Zeeman and quadrupolar spin-lattice relaxation times have been measured at 46.04 MHz on two isotopomers of Azpac (Azpac-d4 and Azpac-d26 , deuteriated on the aromatic core and on the alkoxy chains, respectively) and on HL-d4 , an isotopomer of HL partially deuteriated on the aromatic core, by means of the Wimperis pulse sequence. The spectral densities obtained from the measured relaxation times are discussed in terms of internal and overall molecular motions. A small step rotational diffusion model for the overall molecular motions, superimposed on a free rotational model for internal motions, allowed diffusion coefficients for molecular spinning and tumbling and for phenyl ring rotations to be derived for HL; the same models were used in describing the dynamics of Azpac.
Phase Transition and Crystal Dynamics of 4-Bromobenzyl Alcohol
Authors: Hashimoto Masao , Monobe Yuko , Terao Hiromitsu , Niki Haruo , Mano Koichi
Published: February 2015

For the title compound a phase transition from Phase II to Phase I (low and room temperature phases, respectively) was found at ca. 217 K. The temperature dependence of the 81Br NQR frequency and that of the dielectric constant showed anomalies at ca. 195 K that were tentatively attributed to a higher order phase transition. A similar anomaly was found at ca. 218 K for 4-chlorobenzyl alcohol which showed a II-I transition at 236 K. The dielectric dispersion observed for both compounds at low temperatures indicates an excitation of a molecular motion with the dielectric relaxation rate of ca. 1 kHz. The temperature dependence of the 81Br NQR frequencies of 2-and 3-bromobenzyl alcohol, measured at T > 77 K, gave no evidence of phase transition in their crystals.
2H and 195 Pt NMR Studies of Molecular and Electron Spin Dynamics in Paramagnetic [Cu(H2O)6][PtCl 6]
Authors: Iijima Takahiro , Orii Kengo , Mizuno Motohiro , Suhara Masahiko
Published: February 2015

The temperature dependences of 2H and 195Pt NMR spectra and the spin-lattice relaxation time T1 were measured for [Cu(H2O)6][PtCl6]. From the simulation of 2H NMR spectra, the jump rate of 180° flips of the water molecules (k), the nuclear quadrupole interaction parameters (e2Qq/h, ƞ) and the electron-nucleon dipolar interaction parameter (vD) were obtained. By measuring 2H T1, k was estimated in the temperature range where the spectrum is insensitive to the motion of the water molecules. Above the phase transition temperature, the pre-exponential factor k0 = 8 x1011 s-1 and the activation energy Ea = 15 kJmol-1 for 180° flips of the water molecules were obtained from the spectral simulation and T1. 195Pt NMR spectra showed an axially symmetric and unsymmetric powder pattern of the chemical shift anisotropy at the high and low temperature phase, respectively. For the deuterated compound, the correlation times of the electron spin in Cu2+ were estimated from 195Pt T1 and the activation energy for jumping between the different configurations of Jahn-Teller distortion Δ = 200 K was obtained.
Temperature Dependence of 2H Quadrupole Coupling Constants in 2H2O and Ionic Motions in Crystalline [M(2H2O)6] [SnCl6] (M: Mg, Ca), Studied by 2H NMR and Neutron Powder Diffraction
Authors: Yoshida Naohiro , Onoda-Yamamuro Noriko , Ishimaru Shin'ichi , Horiuchi Keizo , Ikeda Ryuichi
Published: February 2015

The temperature dependence of 2H NMR spectra was measured at 130-430 K on [M(D2O)6] [SnCl6] (M : Mg, Ca) (rhombohedral, space group: R3̅), and neutron powder diffraction on the Mg salt was performed at room temperature. Based on the accurate orientation of D2O molecules in an octahedral cation, spectra with a large asymmetry parameter η, observed around 200 K, were explained by a model of 180° flip of water molecules. Another motional narrowing observed above room temperature was assigned to a cationic overall reorientation about the C3-axis.
209Bi NQR and Magnetic Properties of Bismuth Oxide-Based Compounds
Authors: Kravchenko E. A. , Orlov V. G. , Hai Fam Suan , Kargin Yu. F.
Published: February 2015

The NQR line shapes of 209Bi in the α-Bi2O3-based mixed oxides Bi2O3 • 2M2O3 (M = Al, Ga). Bi2O3 • 3GeO2, and 2Bi2O3 • 3GeO2 are recorded in zero and weak magnetic fields (Hext < 500 Oe) and compared with the results of computer simulation. Splittings and line shape asymmetry, exhibited by the resonances, suggest that internal magnetic fields, similar to those earlier reported for α-Bi2O3 and Bi3O4Br, may exist in these compounds.

In the spectra of single crystal Bi4Ge3O12, the line multiplicity in external magnetic fields is higher than simulated, which might results from domains in the crystal.

In external magnetic fields a notable increase in the line intensity was observed, the effect depending on the mutual orientation of the EFG axes and the fields perturbing the nuclear spin system.

Published: February 2015

The oxygen content dependence of 63Cu NQR at the Cu(1) site and proton NMR have been measured in the antiferromagnetic phase of powdered samples of hydrogen-doped YBa2Cu3O6+xHy (0.07 <̲ x <̲ 0.17 and y ≈ 1) from 4.2 to 90 K. The spectrum of 1H NMR is a single line and the line width increases below 15 K due to magnetic interactions. The enhancements of T1
-1 and T2
-1 of 63Cu(l)NQR occur around 35 and 15 K, respectively. These enhancements increase with increasing oxygen concentration. The maximum values of T1
-1 and T2
-1 for the sample with x = 0.17 reach 200 sec-1 and more than 7 msec-1, respectively. The predominant source for the relaxation mechanism of 63Cu(l) NQR and the line broadening of 1H NMR are found to be the fluctuating magnetic field due to the staggered Cu2+ moments.

The crystal structure of [tri(o-methoxyphenvl)phosphine]2 Cu2Br2 shows it to be a halogen-bridged dimer with three-coordinated Cu (I) sites. The 63Cu NQR frequency of the corresponding chloride indicates that it has a similar structure. The 63Cu NQR frequencies of the complexes of tri(p-tolyl)phosphine, L3Cu2X2 , with cuprous chloride and bromide are consistent with their having halogen-bridged structures with both three- and four-coordinated Cu(I) sites analogous to those formed by triphenyl-phosphine and tri(m-tolyl)phosphine.

ab i/ifüo-Rechnungen zur relativen Stabilität der Neutralmoleküle, Radikalkationen und -anionen von Allen und Propin / ab initio Calculations on the Relative Stabilities of the Neutrals, Radical Cations and Anions of Allene and Propvne
Authors: Frenking Gemot , Schwarz Helmut
Published: February 2015

Ab initio calculations demonstrate that, in agreement with experimental results, the oxidation of both allene (1) and propyne (2) to their corresponding cation radicals (1+·nd 2+·) is associated with a reversal of the stability order. Whereas for the neutral molecules 1 is thermochemically less stable than 2 (⊿⊿Hf° = 1.3 kcal/mol) the opposite holds for the cation radicals (1+· is 13.3 kcal/mol more stable than 2+·). The radical anions of 1 and 2 do also show a reversed stability order (1+· being 5.1 kcal/mol more stable than 2-·); however, both radical anions are predicted to undergo spontaneous electron detachement, thus giving their neutral counterparts (negative electron affinities). The changes in geometries and charge distributions associated with the redox reactions of 1 and 2 are briefly discussed

Cochrum, RG, Connors, RT, Coons, JM, Fuller, DK, Morgan, DW, and Caputo, JL. Comparison of running economy values while wearing no shoes, minimal shoes, and normal running shoes. J Strength Cond Res 31(3): 595–601, 2017—The purpose of this study was to quantify differences in running economy (RE) at 50 and 70% of each subject's velocity at V̇o
2max (vV̇o
2max) across barefoot and 2 mass, stack height, and heel-to-toe-drop controlled footwear conditions (minimal shoes and normal running shoes) in 9 recreational distance runners (mean age 26.8 ± 6.8 years). Over 3 days, subjects ran in one of the footwear conditions while RE (oxygen consumption) and step frequency were measured at each speed with a 5-minute rest between each trial. A 2-way repeated-measures multivariate analysis of variance (p ≤ 0.05) and Bonferroni-adjusted follow-up analyses revealed that RE was not significantly different across footwear conditions at either speed. However, those running barefoot exhibited a higher step frequency than when running in minimal (50%, p = 0.007; and 70%, p < 0.001) and standard footwear conditions (70% only, p < 0.001). Higher step frequencies were also exhibited by those running in minimal versus standard footwear (70% only, p = 0.007). Thus, RE is not affected by footwear or running barefoot in those with experience running in minimal-type footwear. Significant adjustments in step frequency when alternative footwear was introduced may help explain why RE was statistically maintained during each footwear and speed condition across but not between subjects. Therefore, determination of footwear for the enhancement of RE should be based on individual physical characteristics and preferences rather than a global recommendation of an economical running shoe.

Orr, RM, Ford, K, and Stierli, M. Implementation of an ability-based training program in police force recruits. J Strength Cond Res 30(10): 2781–2787, 2016—Currently, police recruit physical training programs generally use group-based runs of a “1 size fit all” approach. The aim of this study was to assess the impact of an ability-based training (ABT) program, as derived from the 30-15 Intermittent Fitness Assessment, on the metabolic fitness and injury rates of police recruits undergoing basic training. Police recruits completing two different stages of training (session 1: n = 54 and session 2: n = 233) were randomly assigned to either a control group (CG) (standard group running) or an intervention group (IG) (ABT program). Physical training was completed once a week over a 10-week period. Aerobic fitness was measured through 20-m progressive shuttle run test performance. Injury data were captured through formal accident and incident forms. Results found that aerobic fitness was maintained but not significantly improved in both groups for session 1, with no significant differences between the groups after training. In session 2, both groups significantly improved their aerobic fitness (p < 0.001), whereas the IG to a greater degree, with no significant differences between the groups after training. There were no significant differences in injury rates between groups (session 1: χ2(1) = 1.533, p = 0.216; session 2: χ2(1) = 1.252, p = 0.263). However, the IGs had a significantly lower relative risk (RR) of injury when compared with the CGs (group 1: RR = 0.31, p = 0.28; group 2: RR = 0.59, p = 0.24). The results suggest that coaches may benefit from implementing ABT programs in tactical populations and achieve the same or better fitness gains with a lower risk of injuring recruits.

The maritime historian working as litigation support and expert witness faces many challenges, including identifying and analyzing case law associated with admiralty subjects, cultural resource management law, and general historical topics. The importance of the unique knowledge of the historian in the maritime context is demonstrated by a case study of attempts to salvage the shipwreck Atlantic, the remains of a merchant vessel built and enrolled in the United States and lost in the Canadian waters of Lake Erie in 1852.
Why Litigation-Driven History Matters
Authors: Zahniser Keith A.
Published: February 2015

Litigation drives extensive historical research but often allows only select observers to see the results. Historians have conducted untold studies for litigation that become “secret histories” because these histories are not published. An example is the historical use and regulation of the chemical trichloroethylene (TCE), a hazardous chemical at issue in much environmental litigation, but a topic virtually absent in the secondary literature. This practice seems to contravene accepted standards of open scholarship. Although not directly aligned with the traditional academic model of historical practice, however, historical research and writing for litigation achieve legitimate and important results without abandoning the discipline’s professional standards. History done by consultants for litigation is neither a history of compromised standards nor as “secret” as feared.
Indigenous Space and the Landscape of Settlement

Published: February 2015

This essay examines my work as expert witness in the case of U.S. v. Michigan, a Indigenous use-rights case. I was charged with parsing the intention of a specific article of the 1836 Treaty of Washington compelling land cession by Anishinaabe peoples and with writing a history of land use in the area from that date to the present for the Chippewa Ottawa Resource Authority (my employer). The challenges were not only methodological (how do you estimate use from ownership?) and epistemological (what constitutes proof that will satisfy both historians and lawyers?), but also sociological and psychological: what happens when an associate professor puts her progress toward full professor on hold for the sake of a court case?
From Archive to Evidence
Authors: Stevens Jennifer A.
Published: February 2015

Within the field of natural resource law are several specific areas that are well suited for the historian’s skillset and knowledge. The deployment of the historian’s tool box when conducting research in the legal world, however, can result in deliverables which vary significantly from those found in the academy, as they range widely in both size and scope and do not always use the full range of a historian’s skills. New technological platforms provide consulting historians with creative opportunities to disseminate valuable information and sources and enhance important scholarly debates.

Cadmium Chloride Assisted Re-Crystallisation of CdTe: The Effect on the CdS Window Layer
Authors: Abbas Ali , Kaminski Piotr , West Geoff , Barth Kurt , Sampath WS , Bowers Jake , Walls John M.
Published: February 2015

The cadmium chloride annealing treatment is an essential step in the manufacture of efficient thin film CdTe solar cells. In previous work we have shown that the primary effect of the treatment is to remove high densities of stacking faults from the as-deposited material. Use of density functional theory has shown that some of the higher energy stacking faults are hole traps. Removal of these defects dramatically improves cell efficiency. In this study we focus on the effect of the activation treatment on the underlying n-type cadmium sulphide layer. A range of techniques has been used to observe the changes to the microstructure as well as the chemical and crystallographic changes as a function of treatment parameters. Electrical tests that link the device performance with the micro-structural properties of the cells have also been undertaken. Techniques used include High Resolution Transmission Electron Microscopy (HRTEM) for sub-grain analysis, EDX for chemical analysis and XPS and SIMS for composition-depth profiling. By studying the effect of increasing the treatment time and temperature, we will show that the cadmium sulphide layer depletes to the point of complete dissolution into the absorber layer. We will also show that chlorine penetrates and decorates the grain boundaries in the cadmium sulphide. In addition we will show that chlorine builds up at the heterojunction and concentrates in voids at the cadmium telluride/cadmium sulphide interface. A combination of these effects damages the electrical performance of the solar cell.

A proporção de idosos no Brasil vem crescendo consideravelmente e essa transição demográfica traz um quadro em que cada vez mais a sobrevivência deles fica dependente de seus familiares. Para aprimorar a qualidade de vida desse grupo há a proposta da elaboração de um programa de capacitação que contribua para melhorar os serviços prestados a estes indivíduos. O objetivo do presente estudo é avaliar um Programa de Capacitação para Cuidadores Informais na qualidade de vida de idosos. Foram realizadas visitas às residências de 15 idosos com déficit de autocuidado, onde foi aplicado o questionário SF-36. Em seguida realizou-se um programa multiprofissional de capacitação para seus cuidadores. Após 2 meses aplicou-se novamente o questionário para verificar a eficácia do programa de capacitação na qualidade de vida dos idosos. Houve um aumento significativo dos escores relacionados ao domínio "saúde mental" e uma diminuição significativa dos relacionados às "limitações por aspectos físicos". A partir dos dados obtidos concluiu-se que deve ser incentivada a formação de grupos de cuidadores informais, conduzidos por profissionais da área de saúde, para fomentar o conhecimento, a troca de experiências e a discussão sobre estratégias para melhorar o ato de cuidar.

Glyphosate-resistant common waterhemp is a difficult-to-control annual broadleaf weed that has become a serious management challenge for growers in Nebraska and other states in the United States. The objectives of this study were to confirm glyphosate-resistant common waterhemp in Nebraska by quantifying level of resistance in a dose-response study, and to determine the sensitivity and efficacy of POST soybean herbicides for controlling suspected glyphosate-resistant common waterhemp biotypes. Seeds of suspected glyphosate-resistant common waterhemp biotypes were collected from seven eastern Nebraska counties. Greenhouse dose-response experiments were conducted to evaluate the response of common waterhemp biotypes to nine rates of glyphosate (0 to 16×). Common waterhemp biotypes were 3- to 39-fold resistant to glyphosate depending on the biotype being investigated and the susceptible biotype used for comparison. Results of the POST soybean herbicides efficacy experiment suggested that glyphosate-resistant biotypes, except a biotype from Pawnee County, had reduced sensitivity to acetolactate synthase (ALS)–inhibiting herbicides (chlorimuron-ethyl, imazamox, imazaquin, imazethapyr, and thifensulfuron-methyl). Glufosinate and protoporphyrinogen oxidase (PPO)–inhibiting herbicides (acifluorfen, fluthiacet-methyl, fomesafen, and lactofen) provided ≥ 80% control of glyphosate-resistant common waterhemp at 21 d after treatment (DAT). This study confirmed the first occurrence of glyphosate-resistant common waterhemp in Nebraska, and also revealed reduced sensitivity to ALS-inhibiting herbicides in most of the biotypes tested in this study.
“Using History to Make Slavery History”: The African American Past and the Challenge of Contemporary Slavery
Authors: Stewart James B.
Published: February 2015

This article argues that contemporary antislavery activism in the United States is programmatically undermined and ethically compromised unless it is firmly grounded in a deep understanding of the African American past. Far too frequently those who claim to be “the new abolitionists” evince no interest in what the original abolitionist movement might have to teach them and seem entirely detached from a U.S. history in which the mass, systematic enslavement of African Americans and its consequences are dominating themes. As a result contemporary antislavery activism too often marginalizes the struggle for racial justice in the United States and even indulges in racist ideology. In an effort to overcome these problems, this article seeks to demonstrate in specific detail how knowledge of the African American past can empower opposition to slavery as we encounter it today.
Queering the Support for Trafficked Persons: LGBTQ Communities and Human Trafficking in the Heartland
Authors: Schwarz Corinne , Britton Hannah E.
Published: February 2015

Human trafficking justice centers on the “Three Ps” model of prevention, protection, and prosecution. While protection and prosecution efforts have been moderately successful, prevention remains elusive, as “upstream” structural fac-tors—class, gender, and sexuality inequalities—remain difficult to target. Individuals who are affected by these factors are not fully served within linear service frameworks. Based on a 12-month study in Kansas City, we find that service providers recognize the limitations of a “one-size-fits all” approach. Using a public health model, our research team con-ducted a public health surveillance, explored risk and protective factors, and facilitated organizational self-assessments of services. Our findings support a prevention approach that supports a survivor-centered model, which creates new, non-linear or queered avenues of agency and community for trafficking survivors. This model allows survivors to make use of services in moments of vulnerability and opt out of others in moments of resilience. Given the systematic cuts in funding that have affected service providers, this research contends that prevention is cheaper, more effective, and more ethical than relying on prosecutions to curb trafficking. Developing a model that fosters survivor empowerment is a key step toward individual justice and survivor resilience for vulnerable and marginalized populations.

Transformation from Within: A Concept Analysis of Epiphany
Authors: Chilton Jenifer M.
Published: February 2015

The aim of this article is to explore the concept of epiphany using a modified version of Walker and Avant's (2005) concept analysis procedures. This transformative experience produces behavior change that can impact wellness. The occurrence of epiphanies through analysis of historical figures, retrospective and qualitative studies, and literary works is described. Evidence suggests this phenomenon can be profound, liberating, and enduring. Nursing research has not considered the potential of epiphanies as a behavior change theory to improve health behaviors and wellness.
Primary Nursing in a Short-Stay Unit
Authors: Baynton Jane
Published: February 2015

Primary Nursing is a model of care delivery that has been shown to improve the quality of care provided to patients and enhance the nurse–patient relationship. Although there is considerable attention in the literature on Primary Nursing concerning inpatient hospital units, there has been no discussion of Primary Nursing in short-stay units. Our hospital aimed to introduce Primary Nursing into all the units including short-stay. Staff were educated about the role of the primary nurse using Koloroutis's (2004) Relationship-Based Care model, comprising three crucial relationships: care provider's relationship with patients and families, with self, and with colleagues. The primary nurse develops the plan of care for individual patients based on their therapeutic relationship, which is sustained for the patient's length of stay in the unit.
To Move Health Care to Health Caring: A Conversation with Julie Kennedy Oehlert, DNP, RN

Published: February 2015

The complex nature of health care requires a culture of interprofessionality that supports high-functioning interprofessional teams. Wolf and Prince (2014) wrote, “Culture is the foundation on which any healthcare encounter is delivered” (p. 3). It is therefore important for nursing to elevate thought leaders who can address the culture of health care organizations and how culture can be transformed. Julie Kennedy Oehlert is one of these leaders.
Cognitive Behavioral Therapy in Patients with Sickle Cell Disease
Authors: Daniels Sheena
Published: February 2015

Introduction

Sickle cell disease (SCD) is an inherited autosomal recessive disorder. In the United States, most individuals with SCD are African Americans, with an incidence of 1 in 400 to 1 in 500 live births. SCD is a lifelong disorder with no known cure.

Background

SCD causes anemia, frequent painful episodes, and reduced life expectancy. The most disturbing clinical problem associated with SCD is severe pain episodes, the most common reason for hospitalization. Pharmacological interventions have been the mainstream for treatment; however, psychological interventions such as cognitive behavioral therapy (CBT) may complement current medical treatment, leading to better coping and overall improved quality of life.

Methods

In a quasi-experimental one-group pretest–posttest study, 9 African American individuals with SCD completed 3 weekly educational sessions learning CBT methods.

Results

Participants demonstrated increased frequency of use of CBT methods post-intervention, including diverting attention, coping self-statements, and behavioral activities, leading to better pain control. However, quality of life and role limitation did not show significant improvement.

Discussion

CBT may be beneficial to those suffering from SCD when combined with conventional treatment options; however, there are still barriers to incorporating psychological interventions into practice.

Conclusions

CBT shows promise for individuals with chronic conditions such as SCD, but more investigation into its efficacy is needed with larger sample sizes over longer periods of time.
Ask “Why” and Don't be Afraid to Say “No”
Authors: Oster Randi Redmond
Published: February 2015

The author of Questioning Protocol: How One Mom Dispensed Equal Doses of Humor, Humility, and Corporate Smarts to Help Her Family Navigate Their Health Care Crisis describes advocating for her chronically ill son in the hospital. The skills she gained working for 18 years as an engineer with General Electric empowered her to navigate the health care system effectively and find opportunities for process improvements. Best practices can be shared between companies, and the same is true for patients and loved ones. This adaptation of a passage from Questioning Protocol demonstrates a critical corporate survival skill: the confidence to say “No.”
Solutions That Stick: Activating Cross-Disciplinary Collaboration in a Graduate-Level Public Health Innovations Course at the University of California, Berkeley
Authors: Sandhu Jaspal S. , Hosang Robert (Nap) , Madsen Kristine A.
Published: February 2015

Since 2011 we have taught a public health innovations course at the University of California, Berkeley. Students gain skills in systematic innovation, or human-centered design, while working in small interdisciplinary teams on domestic and global health projects with client organizations.

To support acquisition of meaningful problem-solving skills, we structured the course so that the majority of learning happens in scenarios that do not involve faculty. Taken by students representing 26 graduate programs (as diverse as epidemiology, city planning, and mechanical engineering), it is one of the 10 highest-rated courses offered by the School of Public Health.

We present the blueprints for our course with the hope that other institutions whose students could benefit will borrow from our model.
Methodological Innovations in Public Health Education: Transdisciplinary Problem Solving
Authors: Lawlor Edward F. , Kreuter Matthew W. , Sebert-Kuhlmann Anne K. , McBride Timothy D.
Published: February 2015

In 2008, the faculty of the Brown School at Washington University in St. Louis designed a Master of Public Health program centered on transdisciplinary problem solving in public health.

We have described the rationale for our approach, guiding principles and pedagogy for the program, and specific transdisciplinary competencies students acquire.

We have explained how transdisciplinary content has been organized and delivered, how the program is being evaluated, and how we have demonstrated the feasibility of this approach for a Master of Public Health degree.
Innovations in Graduate Public Health Education: The Instituto Nacional de Salud Pública
Authors: Valladares Laura Magaña , Ávila Mauricio Hernández
Published: February 2015

During the past 10 years, the Instituto Nacional de Salud Pública (National Institute of Public Health) in Mexico has meticulously revised its educational model. This analysis resulted in the transformation of its educational model by tracing a new path in the pedagogical structure and faculty development to meet current challenges and students’ needs.

The first stage dealt with the national and international accreditation standards that came with the 21st century. The second stage responded to evidence of cognitive research showing that students are better prepared when they are engaged, active, and responsible for their own learning.

This transformation was grounded on the use of information and communication technologies and on a competency-based educational approach that has led the expansion and innovation of educational practice.
Public Health as a Catalyst for Interprofessional Education on a Health Sciences Campus
Authors: Uden-Holman Tanya M. , Curry Susan J. , Benz Loretta , Aquilino Mary Lober
Published: February 2015

Although interprofessional education (IPE) has existed in various formats for several decades, the need for IPE recently has taken on renewed interest and momentum. Public health has a critical role to play in furthering IPE, yet schools of public health are often underrepresented in IPE initiatives. The University of Iowa College of Public Health is serving as a catalyst for IPE activities on our health sciences campus, which includes colleges of dentistry, medicine, nursing, pharmacy, and public health. IPE-related activities have included campus visit by IPE leaders, administration of the Survey of Critical Elements for Implementing IPE, administration of the Interprofessional Learning Opportunities Inventory survey, the development of a comprehensive strategic plan, and the pilot of an IPE course for all first-year prelicensure students and Master of Health Administration students. Although more work is needed to more fully integrate IPE into the curriculum, success to date of the University of Iowa IPE initiative demonstrates that public health can play a critical role as a convener and catalyst for IPE curricular innovations on a health sciences campus.
Preparing Future Faculty and Professionals for Public Health Careers
Authors: Koblinsky Sally A. , Hrapczynski Katie M. , Clark Jane E.
Published: February 2015

Recent years have brought rapid growth in schools of public health and an increasing demand for public health practitioners. These trends highlight the need for innovative approaches to prepare doctoral graduates for academic and high-level practice positions.

The University of Maryland’s School of Public Health developed a “Preparing Future Faculty and Professionals” program to enrich the graduate education and professional development of its doctoral students.

We describe the program’s key elements, including foundational seminars to enhance students’ knowledge and skills related to teaching, research, and service; activities designed to foster career exploration and increase competitiveness in the job market; and independent, faculty-mentored teaching and research experiences. We present a model for replicating the program and share student outcomes of participation.
The Integrated First Year Experience in the Master of Public Health Program
Authors: Dewar Diane M. , Bloom Michael S. , Choi Hyunok , Gensburg Lenore , Hosler Akiko
Published: February 2015

Schools of Public Health historically introduced core curriculum courses in the first year of the Master of Public Health program as independent perspectives; these perspectives included epidemiology, biostatistics, environmental health, public health biology, health behaviors, and health policy.

We performed a pilot project that integrated the core areas around diabetes as a cross-cutting public health issue to provide early exposure to the interdisciplinary nature of public health. In each core curriculum course, diabetes was explored in the curriculum and related to other core courses.

Based on positive evaluations, this project will be replicated using a different health issue. Such an issue can be easily introduced as an overarching umbrella under which students are motivated to work through interdisciplinary collaboration.
