Published: May 2018

Hypertensive disorders of pregnancy are the second leading cause of maternal deaths worldwide. Superimposed preeclampsia is an increasingly common problem and often associated with impaired placental perfusion. Understanding the underlying mechanisms and developing treatment options are crucial. The pregnant stroke-prone spontaneously hypertensive rat has impaired uteroplacental blood flow and abnormal uterine artery remodeling. We used Ang II (angiotensin II) infusion in pregnant stroke-prone spontaneously hypertensive rats to mimic the increased cardiovascular stress associated with superimposed preeclampsia and examine the impact on the maternal cardiovascular system and fetal development. Continuous infusion of Ang II at 500 or 1000 ng/kg per minute was administered from gestational day 10.5 until term. Radiotelemetry and echocardiography were used to monitor hemodynamic and cardiovascular changes, and urine was collected prepregnancy and throughout gestation. Uterine artery myography assessed uteroplacental vascular function and structure. Fetal measurements were made at gestational day 18.5, and placentas were collected for histological and gene expression analyses. The 1000 ng/kg per minute Ang II treatment significantly increased blood pressure (
P
<0.01), reduced cardiac output (
P
<0.05), and reduced diameter and increased stiffness of the uterine arteries (
P
<0.01) during pregnancy. The albumin:creatinine ratio was increased in both Ang II treatment groups (
P
<0.05;
P
<0.0001). The 1000 ng/kg per minute–treated fetuses were significantly smaller than vehicle treatment (
P
<0.001). Placental expression of Ang II receptors was increased in the junctional zone in 1000 ng/kg per minute Ang II–treated groups (
P
<0.05), with this zone showing depletion of glycogen content and structural abnormalities. Ang II infusion in pregnant stroke-prone spontaneously hypertensive rats mirrors hemodynamic, cardiac, and urinary profiles observed in preeclamptic women, with evidence of impaired fetal growth.
Drums, Hearts, Bulls, and Dead Gods: The Theology of the Ancient Mesopotamian Kettledrum
Authors: Gabbay Uri
Published: May 2018

The article deals with the theology of the lilis kettledrum, used to accompany prayers in ancient Mesopotamian temple cult. The article analyzes the ritual in which the head of the kettledrum was covered with the hide of a bull and the ancient commentary on this ritual, showing that the ancient understanding of this ritual was that it reflected the primordial battle between the gods Enlil and Enmešara over the rule of the universe. The article connects this myth to other mythical episodes, such as the myths of the Bull of Heaven, Anzu, and Atra-ḫasīs. The analysis of these materials leads to the conclusion that the playing of the kettledrum during the performance of ancient Mesopotamian prayers symbolized the beating heart of the deities to whom the prayers were addressed.

The cotton mealybug,Phenacoccus solenopsisTinsley (Hemiptera: Pseudococcidae), is an invasive pest of cotton, apart from several other important crops, and poses a serious threat to agricultural economy all over the world. Studies on the biology and population growth parameters ofP. solenopsison the five most preferred host plants, namely cotton (Gossypium hirsutumL.) (Malvaceae), China rose (Hibiscus rosa-sinensisL.) (Malvaceae), tomato (Lycopersicon esculentumMill.) (Solanaceae), congress grass (Parthenium hysterophorusL.) (Asteraceae) and okra (Abelmoschus esculentus(L.) Moench) (Malvaceae) were undertaken in the laboratory under controlled temperature and relative humidity. The mean cumulative development time of females was 16.61 days on cotton, 14.16 days on China rose, 14.13 days on okra, 14.00 days on tomato and 13.57 days on congress grass. The longest oviposition period was recorded on cotton (15.20 ± 1.87 days), while it was in the range of 9-10 days in the remaining host plants. Females lived longer (27.40 ± 1.76 days) when reared on cotton, while their life was shortest on tomato (14.60 ± 0.96 days). The highest fecundity was observed on cotton (328.30 ± 23.42), whereas it was found to be in the range 178-212 on the other hosts. The survival frequency from crawler to adult in females was highest on cotton (27.53%), while it was the lowest on tomato (15.87%). The highest net reproductive rate (284.3 females/female/generation), mean length of a generation (31.24 days), and intrinsic rate of increase (0.19 day−1) were recorded on cotton. The finite rate of increase was in the range of 1.18-1.20 (females/female/day) for all the selected host plants. The weekly multiplication rate was highest on China rose and congress grass (3.78), while it was the least on tomato (3.28). The corrected generation time was dissimilar in all the selected host plants, being highest on cotton (31.39 days) and the least on congress grass (27.71 days). The doubling time was shortest on congress grass (3.61 days), while it was longest on tomato (4.11 days). Hence, the host plant species significantly affects population growth ofP. solenopsis.
Creating Cinderella? The Unintended Consequences of the Women Peace and Security Agenda for EU’s Mediation Architecture
Authors: Haastrup Toni
Published: May 2018

In 2000, the United Nations (UN) launched the Women, Peace and Security (WPS) agenda by adopting Security Council Resolution 1325. The agenda, among other things, called for the greater inclusion of women in peace negotiation practices and structures. While the European Union (EU) has made commitments to implementing theWPSagenda, the literature has not yet captured the institutional dynamics of theEUas it seeks to translate theWPSagenda into reality. This article takes stock of this hitherto excluded area of research. It argues that mediation is the ‘Cinderella’ of theEU’s peace and security institution because it has been ignored as a site for the implementation of theWPSagenda with important implications. Using a feminist institutionalist framework, the article shows the ways in which institutional practices of change aimed at including the new perspectives prompted by theWPSagenda lead to unintended gendered consequences.
The EU as a Multi-Mediator: The Case of the Democratic Republic of Congo
Authors: Davis Laura
Published: May 2018

In the 1990s, the Democratic Republic of Congo (DRC) experienced complex wars involving local, national and regional combatants and conflict drivers, which formally ended in 2002. Violence continued and the government and rebel groups negotiated a series of peace deals, most recently in 2013. The European Union (EU) has been engaged in theDRCsince the 1990s. This article proposes a model for conceptualizingEUmediation engagement within the conflict and process contexts, and the necessary capabilities for different types ofEUmediation. It uses theDRCcase study to examine how differentEUcapabilities were engaged in various peace processes which addressed multiple layers of a complex situation, and also engaged with other external actors in a multilateral environment. It concludes that theEUcan be conceptualized as a multi-mediator and identifies the necessary capabilities for this.

Authors: DOĞAN CAHİT , ERDEM SEDAT ÖMER
Published: May 2018

Palynological characteristics of 11 taxa belonging to the genus Arenaria (Caryophyllaceae) have been examined. Pollen grains in the pollen slides, which were prepared according to the method of acetolysis, morphological features were determined with light microscope and also with SEM, then microphotographs of pollens were taken. Morphological examinations were performed on the part of the work carried out with light microscope, pollen sizes, pore sizes and numbers were observed to vary between taxa. The pollen type of the studied taxa is pantoporate (periporate), pollen shape is prolate spheroidal, exine structure is subtectate, the ornamentation is microechinate-perforate. The pores are covered with operculum and the surface of the operculum is microechinate. According to the results of the study, pollen definitions of the taxa were made. Based on different palyno-morphological characters, a taxonomic key was develop for quick and accurate identification. The results of the study corroborate that morphological features, such as axes, aperture number, Plg, and Plt diameter and distance between pores, show differences which can be taken into consideration in the systematic discrimination within the groups, and also for discrimination of the taxa in the genus Arenaria.

Published: May 2018

Two new species of diminutive, sympatric, lowland, leaf-litter skinks of the genus Tytthoscincus Linkem, Diesmos & Brown from the Sekayu region of Hulu Terengganu, Terengganu State in northeastern Peninsular Malaysia are described on the basis genetic and morphological data. One of the new species, T. monticolus sp. nov., was collected in a hilly riparian area along Sungai (=river) Bubu and is most closely related to an undescribed species from the Tembak Reservoir area. The other, T. keciktuek sp. nov. collected along Sungai Peres, is most closely related to T. perhentianensis Grismer, Wood, & Grismer from Pulau (=island) Perhentian Besar. Sympatry and syntopy of multiple, specialized, unrelated, leaf-litter species of Tytthoscincus was previously only known from upland areas and these new species represent the first example of lowland of sympatry. More importantly, however, these endemic species add to a growing body of research and discoveries that continue to underscore the unrealized biodiversity of the riparian systems of Hulu Terengganu and the Sekayu region and their need for protection and continued study.
Satellite-Observed Precipitation Response to Ocean Mesoscale Eddies
Authors: Liu Xue , Chang Ping , Kurian Jaison , Saravanan R. , Lin Xiaopei
Published: May 2018

Among various forms of atmospheric response to ocean mesoscale eddies, the rainfall response is the most difficult to quantify and is subject to considerable uncertainty. Here the robustness of the rainfall response is examined by comparing three different satellite-derived rainfall datasets: the Tropical Rainfall Measuring Mission (TRMM) Multisatellite Precipitation Analysis (TMPA), NOAA Climate Prediction Center (CPC) morphing technique (CMORPH) global precipitation, and the newly available Integrated Multisatellite Retrievals for Global Precipitation Measurement (IMERG) that is based on the latest remote sensing technology with finer spatial and temporal resolution. Results show that all datasets exhibit a similar rainfall response to ocean eddies, but the amplitude of the rainfall response is much stronger in IMERG than in the other two, despite the fact that IMERG provides the weakest time-mean rainfall estimate. In situ validation against the NOAA’s Ocean Climate Stations Project (OCS) Kuroshio Extension Observatory (KEO) buoy rainfall measurement shows that IMERG is more accurate in estimating both the mean value of rainfall and its intensity distribution than the other two products, at least in the Kuroshio Extension region. Further analysis reveals that 1) eddy-induced precipitation response is significantly stronger in winter than in summer, and 2) warm-eddy-induced rainfall response is considerably stronger than cold-eddy-induced response, and these asymmetries in rainfall response are more robust in IMERG than in the other two datasets. Documenting and analyzing these asymmetric rainfall responses is important for understanding the potential role of ocean eddies in forcing the large-scale atmospheric circulation and climate.
Synoptic-Scale Control over Modern Rainfall and Flood Patterns in the Levant Drylands with Implications for Past Climates
Authors: Armon Moshe , Dente Elad , Smith James A. , Enzel Yehouda , Morin Efrat
Published: May 2018

Rainfall in the Levant drylands is scarce but can potentially generate high-magnitude flash floods. Rainstorms are caused by distinct synoptic-scale circulation patterns: Mediterranean cyclone (MC), active Red Sea trough (ARST), and subtropical jet stream (STJ) disturbances, also termed tropical plumes (TPs). The unique spatiotemporal characteristics of rainstorms and floods for each circulation pattern were identified. Meteorological reanalyses, quantitative precipitation estimates from weather radars, hydrological data, and indicators of geomorphic changes from remote sensing imagery were used to characterize the chain of hydrometeorological processes leading to distinct flood patterns in the region. Significant differences in the hydrometeorology of these three flood-producing synoptic systems were identified: MC storms draw moisture from the Mediterranean and generate moderate rainfall in the northern part of the region. ARST and TP storms transfer large amounts of moisture from the south, which is converted to rainfall in the hyperarid southernmost parts of the Levant. ARST rainfall is local and intense, whereas TP rainfall is widespread and prolonged due to high precipitation efficiency and large-scale forcing. Thus, TP rainfall generates high-magnitude floods in the largest catchments; integration of numerous basins leads to sediment feeding from the south into the Dead Sea, exhibited in large sediment plumes. Anecdotal observations of the channel with the largest catchment in the region (Nahal HaArava) indicate that TP floods account for noticeable geomorphic changes in the channel. It provides insights into past intervals of increased flash flood frequency characterized by episodes of marked hydrogeomorphic work; such an increase is especially expected during intervals of southerly situated and southwesterly oriented STJs.
Dividing the Grey Divide: Deconstructing Myths About Older Adults’ Online Activities, Skills, and Attitudes
Authors: Quan-Haase Anabel , Williams Carly , Kicevski Maria , Elueze Isioma , Wellman Barry
Published: May 2018

Although research has demonstrated a grey divide where older adults are less involved and skilled with digital media than younger adults, by treating them as a homogenous group, it has overlooked differences in their digital skills and media use. Based on 41 in-depth interviews with older adults (aged 65+ years) in East York, Toronto, we developed a typology that moves beyond seeing older adults as Non-Users to include Reluctants, Apprehensives, Basic Users, Go-Getters, and Savvy Users. We find a nonlinear association between older adults’ skill levels and online engagement, as many East York older adults are not letting their skill levels dictate their online involvement. They engage in a wide range of online activities despite having limited skills, and some are eager to learn as they go. Older adults often compared their digital media use with their peers and to more tech-adept younger generations, and these comparisons influenced their attitudes toward digital media. Their narratives of mastery included both a positive sense that they can stay connected and learn new skills and a negative sense that digital media might overwhelm them or waste their time. We draw conclusions for public policy based on our findings on how digital media intersect with the lives of East York older adults.
Establishing the Need for an Evidence-Based Treatment Algorithm for Peritonsillar Abscess in Children
Authors: Grant Maria Carratola , Raggio Blake , Barton Blair , Guarisco J. Lindhe
Published: May 2018

In this retrospective case series, we report clinical factors associated with pediatric peritonsillar abscess (PTA), with hopes of contributing to the design of an evidenced-based, economic treatment approach. Charts were examined for presenting symptoms and signs. Each of these were analyzed for association with the presence of PTA and for association with treatment. We found that, with the exception of leukocytosis, the signs/symptoms that prompted treatment correlate with those that indicate the presence of PTA. However, there are several signs/symptoms, namely, referred otalgia, cervical lymphadenopathy, and decreased oral intake, that were associated with PTA but unassociated with treatment. Treatment can be aided by establishing an algorithm that accounts for the symptoms/signs most correlated with true, drainable abscess.
“Each Creature, Resplendently Transfigured”: Development of Teaching in Laudato Si’
Authors: O’Halloran Nathan W.
Published: May 2018

Three stages can be traced in the Catholic Church’s magisterial teaching on the status of nonhuman creatures in the eschatological New Creation. In this article I ask three questions: which, why, and how: Which creatures are in the new creation, why are they part of the New Creation, and how will they be there? I argue that Laudato Si’ gives a new magisterial answer to these three questions and constitutes an important new development in the teaching on New Creation.
A Trinitarian Basis for a “Theological Ecology” in Light of Laudato Si’
Authors: Schlesinger Eugene R.
Published: May 2018

This article responds to Pope Francis’s call in Laudato Si’ for an ecological expansion of mission and seeks to provide it with theological support. This support comes by way of a trinitarian rendition of the missiological concept missio Dei. Drawing from Thomas Aquinas and Bernard Lonergan’s accounts of the trinitarian missions, it articulates a theological ecology (as opposed to an ecological theology), in which the traditional doctrine of God is the controlling motif. Through the missions of the Son and Holy Spirit, God transforms the moral-intellectual-volitional comportment of humanity and recruits them into a shared mission of environmental concern.
Spirituality, Evolution, Creator God
Authors: Haight Roger
Published: May 2018

Evolution raises problems for some Christian beliefs, such as the character of God’s creating act, whether God intervenes in nature’s consistency, God’s purpose in the light of nature’s randomness, and whether we can refer to anything specific God does in history. This article addresses these issues first with some abstract conceptions of God, and then with considerations of the nature of God creating, the immanence and transcendence of God, and God’s “action” in the world. It concludes with reflections on the Christian life in the light of this theological construction.
Of All Things, Seen and Unseen: Josef Pieper’s Negative Philosophy, Science, and Hope
Authors: Warne Nathaniel A.
Published: May 2018

Looking at the relationship between theological, philosophical, and scientific methods within the thought of twentieth-century philosopher Josef Pieper, the author argues that Pieper’s perspective is that theology, philosophy, and science are limited in their ability to obtain knowledge because they are human methods of inquiry. However, theology and philosophy as conceived by Pieper welcome this restriction while modern mechanistic views of science deny it. This article focuses on the distinctive differences that Pieper sees between philosophy as an apophatic discipline and modern scientific methods. It concludes with a discussion on the relationship between philosophy and the virtue of hope.
Comparing the Hospital-Acquired Condition Reduction Program and the Accreditation of Cancer Program: A Cross-sectional Study
Authors: Spaulding Aaron , Paul Rachel , Colibaseanu Dorin
Published: May 2018

Under the Hospital-Acquired Condition Reduction Program (HACRP), introduced by the Affordable Care Act, the Centers for Medicare and Medicaid must reduce reimbursement by 1% for hospitals that rank among the lowest performing quartile in regard to hospital-acquired conditions (HACs). This study seeks to determine whether Accredited Cancer Program (ACP) hospitals (as defined by the American College of Surgeons) score differently on the HACRP metrics than nonaccredited cancer program hospitals. This study uses data from the 2014 American Hospital Association Annual Survey database, the 2014 Area Health Resource File, the 2014 Medicare Final Rule Standardizing File, and the FY2017 HACRP database (Medicare Hospital Compare Database). The association between ACPs, HACs, and market characteristics is assessed through multinomial logistic regression analysis. Odds ratios and 95% confidence intervals are reported. Accredited cancer hospitals have a greater risk of scoring in the Worse outcome category of HAC scores, vs Middle or Better outcomes, compared with nonaccredited cancer hospitals. Despite this, they do not have greater odds of incurring a payment reduction under the HACRP measurement system. While ACP hospitals can likely improve scores, questions concerning the consistency of the message between ACP hospital quality and HACRP quality need further evaluation to determine potential gaps or issues in the structure or measurement. ACP hospitals should seek to improve scores on domain 2 measures. Although ACP hospitals do likely see more complex patients, additional efforts to reduce surgical site infections and related HACs should be evaluated and incorporated into required quality improvement efforts. From a policy perspective, policy makers should carefully evaluate the measures utilized in the HACPR.

Students also reported that the project helped them better understand the workplace and define career goals.
‘It Depends’: A qualitative study on how adolescent students explain bystander intervention and non-intervention in bullying situations
Authors: Thornberg Robert , Landgren Lena , Wiman Erika
Published: May 2018

The aim of the current study was to examine how junior high school students interpret, motivate, and explain various bystander behaviors in bullying situations. The participants were 17 junior high school students recruited from four schools in Sweden. Semi-structured interviews were conducted and analysed with grounded theory methods. The analysis generated a conceptual model of bystander interpreting–considering process in school bullying. A core category named ‘it depends’ was developed to explain how the participants in the study motivated their own and their peers’ actions as bystanders in various bullying situations. Whether they intervened or not depended on how they interpreted the situation in terms of: (a) seriousness of the situation, including trivialization; (b) social relationships with the involved; (c) locus of responsibility, including displacement of responsibility, and victim blame; (d) social status; (e) perception of risk; and (f) defender self-efficacy. The implications of these results for bullying prevention and intervention efforts are discussed.
Classification of Temporal Bone Pneumatization on High‐Resolution Computed Tomography: Prevalence Patterns and Implications
Authors: Dexian Tan Arthur , Ng Jia Hui , Lim Su Ann , Low David Yong‐Ming , Yuen Heng Wai
Published: May 2018

Objective

The degree of pneumatization of the temporal bone has implications in the pathophysiology and surgical considerations of many temporal bone disorders. This study aims to identify common pneumatization patterns in the petrous apex, mastoid, and infralabyrinthine compartments of the temporal bone. Variables associated with temporal bone pneumatization were also identified.

Study Design

Case series with chart review.

Setting

Single tertiary hospital.

Subjects and Methods

In total, 299 high‐resolution computed tomography scans of the temporal bone performed on patients between 2013 and 2016 were reviewed. Only normal temporal bone scans in patients aged 13 years and older were included. Previously published grading systems were used to classify pneumatization patterns in the petrous apex, mastoid, and infralabyrinthine region.

Results

The most common pneumatization pattern in the petrous apex was group 2 (less than half of the petrous apex medial to the labyrinth is pneumatized), that in the mastoid was group 4 (hyperpneumatization), and that in the infralabyrinthine region was type B (limited pneumatization), at 54.8%, 55.4%, and 76.0% of patients, respectively. Patients with increased pneumatization of 1 temporal bone compartment tended to have increased pneumatization of the same compartment on the contralateral side and the other compartments on the ipsilateral side (P <. 05). Younger age (P <. 001) and male sex (P =. 001) were associated with increased pneumatization in the petrous apex and infralabyrinthine compartments.

Conclusion

The degree of temporal bone pneumatization varies among the different compartments. Age and sex have a significant association with the degree of pneumatization of the petrous apex and infralabyrinthine compartment.
Bullying Experience of Racial and Ethnic Minority Youth in South Korea
Authors: Bae Hwa-ok , Choo Hyekyung , Lim ChaeYoung
Published: May 2018

This study compared bullying experiences between ethnic minority youth and Korean majority youth in South Korea, and examined whether the student-teacher relationship is associated with their bullying experiences. Participants comprised 148 ethnic minority students and 165 Korean majority students in Grades 4 to 11 in South Korea. Bivariate analyses revealed that ethnic minority youth were more likely to be relationally bullied, but were less likely to bully their peers than Korean majority youth. Ethnic minority youth, with Southeast Asian mothers in particular, are most likely to be victimized and least likely to perpetrate bullying. Generalized linear model analyses identified that the youth’s positive perception of teachers decreased the risk of both victimization and perpetration. Policy and practice implications were discussed.
Internal iliac artery balloon occlusion as a hemostatic method for spontaneous rupture of vulvar hematoma during delivery: A case report
Authors: Wan Li , Wang Hongjing , Xu Ke , Yang Lingyun
Published: May 2018

Spontaneous rupture of a vulvar hematoma during delivery is a relatively uncommon event and may cause excessive hemorrhage. Exact identification of anatomic structures and bleeding points is challenging. We herein present a case involving a pregnant woman at 39 weeks’ gestation with a large vulvar hematoma that spontaneously ruptured during the second stage of labor, likely due to rupture of varices in the vulva or vagina. It was difficult to accurately expose and suture the deep bleeding points. The estimated blood loss volume was 1591 mL, and the hemoglobin concentration dropped from 132 g/L before delivery to 84 g/L after delivery. To prevent hemorrhagic shock, bilateral internal iliac artery balloon occlusion was performed and proved to be an effective way to achieve hemostasis. Once hemostasis was established, ligation of the bleeding sites and suturing of all dead space were rapidly completed. Bilateral internal iliac artery balloon occlusion can be used as an effective treatment for excessive vaginal bleeding. The presence of varices or hemangiomas in the vulva or vagina should be carefully checked during antenatal care.
A Pilot Study of Ultrasonography-Naïve Operators’ Ability to Use Tele-Ultrasonography to Assess the Heart and Lung
Authors: Olivieri Peter P. , Verceles Avelino C. , Hurley Julie M. , Zubrow Marc T. , Jeudy Jean , McCurdy Michael T.
Published: May 2018

Introduction:

Remotely tele-mentored ultrasound (RTMUS) involves the real-time guidance of US-naïve providers as they perform point-of-care ultrasound (POCUS) by remotely located, US-proficient providers via telemedicine. The concordance between RTMUS and POCUS in the evaluation of critically ill patients has not been reported. This study sought to evaluate the concordance between RTMUS and POCUS for the cardiopulmonary evaluation of patients in acute respiratory insufficiency and/or shock.

Methods:

Ultrasound-naÏve nurses performed RTMUS on critically ill patients. Concordance between RTMUS and POCUS (performed by critical care fellows) in the evaluation of the heart and lungs was reported. The test characteristics of RTMUS were calculated using POCUS as a gold standard. Concordance between RTMUS and available transthoracic echocardiography (TTE) and computed tomography (CT) scans was also reported.

Results:

Twenty patients were enrolled. Concordance between RTMUS and POCUS was good (90%-100%) for left ventricle function, right ventricle (RV) dilatation/dysfunction, pericardial effusion, lung sliding, pulmonary interstitial syndrome, pleural effusion, and fair (80%) for lung consolidation. Concordance between RTMUS and TTE or CT was similar. RTMUS was highly specific (88%-100%) for all abnormalities evaluated and highly sensitive (89%-100%) for most abnormalities although sensitivity for the detection of RV dilatation/dysfunction (33%) and pulmonary interstitial syndrome (71%) was negatively impacted by false negatives.

Conclusions:

RTMUS may be a reasonable substitute for POCUS in the cardiopulmonary evaluation of patients with acute respiratory insufficiency and/or shock. These findings should be validated on a larger scale.
Psychological Well-Being Among Women Who Experienced Intimate Partner Violence and Received Civil Legal Services
Authors: Renner Lynette M. , Hartley Carolyn Copps
Published: May 2018

Intimate partner violence (IPV) victimization is often associated with negative mental health outcomes; yet, little is known about the psychological well-being of women who experience IPV and receive civil legal services. Civil legal services are not specifically designed to focus on women’s mental health needs but Sullivan’s Social and Emotional Well-Being Framework helps to explain why women receiving this type of formal assistance may demonstrate positive changes in psychological well-being. Using a panel study design and data from 85 women who experienced IPV and sought civil legal services, we examined women’s psychological well-being over a one-year period of time. Approximately two thirds of the women received assistance from Iowa Legal Aid (ILA) for a civil protective order ( n = 56) and the rest were represented in a family law matter. We used measures of mental health (depression, posttraumatic stress disorder [PTSD]) and well-being (social support, resilience, goal directed thinking, empowerment). Our hypotheses that women would experience a decrease in mental health symptoms and an increase in well-being were partially supported. Women reported a decrease in depressive and PTSD symptoms over one year but there were no changes in their goal-oriented thinking or resilience. Implications for practice and future research are included.

Authors: Flynn Jennifer Posa , Gascon Gregg , Doyle Stephen , Matson Koffman Dyann M. , Saringer Colleen , Grossmeier Jessica , Tivnan Valeria , Terry Paul
Published: May 2018

Objective:

To identify and evaluate the evidence base for culture of health elements.

Data Source:

Multiple databases were systematically searched to identify research studies published between 1990 and 2015 on culture of health elements.

Study Inclusion and Exclusion Criteria:

Researchers included studies based on the following criteria: (1) conducted in a worksite setting; (2) applied and evaluated 1 or more culture of health elements; and (3) reported 1 or more health or safety factors.

Data Extraction:

Eleven researchers screened the identified studies with abstraction conducted by a primary and secondary reviewer. Of the 1023 articles identified, 10 research reviews and 95 standard studies were eligible and abstracted.

Data Synthesis:

Data synthesis focused on research approach and design as well as culture of health elements evaluated.

Results:

The majority of published studies reviewed were identified as quantitative studies (62), whereas fewer were qualitative (27), research reviews (10), or other study approaches. Three of the most frequently studied culture of health elements were built environment (25), policies and procedures (28), and communications (27). Although all studies included a health or safety factor, not all reported a statistically significant outcome.

Conclusions:

A considerable number of cross-sectional studies demonstrated significant and salient correlations between culture of health elements and the health and safety of employees, but more research is needed to examine causality.
Pairing Organizational and Individual Factors to Improve Employees’ Risk Responsiveness
Authors: Ford Jessica L. , Stephens Keri K.
Published: May 2018

Scholars and practitioners have established various mechanisms and processes that help safeguard employee health and safety. Extant literature emphasizes the importance of training workers to respond to workplace hazards but often overlooks the influence of organizational factors on employees’ safety behavior. This study surveyed employees at a U.S. oil refinery to assess the influence of both individual and organizational factors on risk responsiveness—behaviors such as having safety conversations at work, possessing self-efficacy, and being willing to respond appropriately to risks. Drawing from prior health communication models, this study develops an integrated model of risk responsiveness. Results suggest that a combination of individual factors and perceptions of organizational information-seeking processes are better predictors of (a) risk-information-seeking behaviors, (b) safety self-efficacy, and (c) risk knowledge than individual-level factors or organizational processes alone. Furthermore, prior near prior near misses or injuries at work had no impact on any of the outcome variables.

Objective: The aim of this article is to study the associations between healthy lifestyle in old age and decline in physical, psychological, cognitive, and social functioning. Method: A population-based sample of 3,107 Dutch men and women aged 55 and 85 years (1992/1993; Longitudinal Aging Study Amsterdam) was used with five 3-yeary follow-up examinations. Lifestyle score, based on smoking status, alcohol consumption, physical activity, and body mass index (BMI), ranged from 0 ( unhealthy) to 4 ( healthy). Outcomes included gait speed, depressive symptoms, cognitive status, and social contacts. Results: Persons with a healthy lifestyle had a 10.6% slower decline in gait speed (0.04 m/s, 95% confidence interval [CI] = [0.03, 0.05]), 10.8% slower increase in depressive symptoms (–1.07 [–1.70, –0.44]), a 1.8% slower decline in cognitive functioning (0.47 [0.23, 0.70]), and a 4.9% slower decline in social contacts (0.58 [0.01, 1.15]) compared with persons with no or one healthy lifestyle factor. Discussion: A healthy lifestyle benefits physical, psychological, cognitive, and social functioning up to very old age.

Published: May 2018

In the present work, a rapid tooling process using three-dimensional printing and pressureless microwave sintering has been developed for the fabrication of biodegradable pure iron. Carbonyl iron particles were used for sample preparation and phosphate-based investment material was used for mould fabrication. Cylindrical samples were fabricated successfully using the developed rapid tooling process. The fabrication experiments were planned based on response surface methodology to evaluate the effect of microwave sintering parameters, namely sintering temperature, heating rate and soaking time on sintered density, shrinkage and compressive yield strength. The results showed that sintered density and compressive yield strength increased with the rise in sintering temperature from α to γ iron transformation temperature and were found to decrease with further rise in temperature. The shrinkage was found to increase with the increase in sintering temperature. Moreover, with the increase in soaking time and decrease in heating rate, sintered density, shrinkage and compressive yield strength were found to increase. Scanning electron microscopy and the X-ray diffraction plot of the fabricated iron samples showed that even without the application of pressure proper bonding of carbonyl iron particles was achieved. Mould material contamination or oxidation was not evidenced in the experiments. A multi-objective optimization using genetic algorithm was performed to obtain optimum microwave sintering parameters for maximum sintered density as well as compressive strength and minimum shrinkage. A case study on the fabrication of scaffold for human skull was performed to test the efficacy of the developed rapid tooling process.

Diffusers are typically used in motorsport to generate negative lift (downforce). They also reduce aerodynamic drag and so significantly enhance aerodynamic efficiency. The amount of downforce generated is dependent on ride height, diffuser ramp angle and its relative length to that of the vehicle length. This paper details a numerical investigation of the effects of ride height and diffuser ramp angle in order to find an optimum downforce and efficiency for the inverted Ahmed model. A short and long diffuser with ratios of 10% and 35%, respectively, to that of vehicle length are studied. The short diffuser produced lower maximum downforce and efficiency at a lower ride height and lower angle when compared to the longer diffuser. The long diffuser produced highest downforce and the best efficiency with a ramp angle of 25° at ride height ratio of 3.8% when compared to vehicle length. Different ride heights were found to correspond to different diffuser ramp angles to achieve optimum downforce and efficiencies.

The stabilities of the handling and rollover are the two important performance of the vehicle and play an important role in vehicle safe driving. Focusing on improving the handling and rollover stabilities, a new approach to realize the coordinated control of the electronic stability program and the active suspension system is proposed. The vehicle model including the active suspension system has been built. The distance between vehicle centroid and the front and rear axles is estimated by the forgetting factor recursion least squares method on the basis of the vertical motion of the vehicle. The parameter self-tuning fuzzy proportional–integral–derivative control of the electronic stability program is adopted and the 2-degree-of-freedom vehicle model considering the changes of the distance between vehicle centroid and the front and rear axles is treated as the reference model. The active suspension system controller is designed according to the different functions of the active suspension system in different vehicle status areas. The function allocation controller is also designed using multi-objective fuzzy decision, which is used to realize the allocation control of the active suspension system and electronic stability program. Under the double-lane change conditions, the function allocation control has been simulated based on MATLAB/Simulink software, which results indicate that the function allocation control strategy of electronic stability program and active suspension system can significantly improve the manipulation and rollover stability of the vehicle at a high speed under emergency steering. Finally, the function allocation controller is installed to the active suspension system and electronic stability program hardware-in-loop test platform, and the hardware-in-loop test has been done, which results are consistent with the results of simulation.

Phaistos was one of the most important Minoan palaces in Crete and previous studies have addressed its relationship with the paleo-seashore position during historical times. Here, we reconstruct the environmental evolution of Phaistos from Early Minoan to Roman times. Study of two stratigraphic sections and nine boreholes drilled in the westernmost part of the Messara Plain has revealed the stratigraphy of the Mid- to Late-Holocene sediments. Laboratory analyses comprise granulometry, magnetic susceptibility measurements and identification of mollusks, diatoms and pollen grains. Eighteen radiocarbon dates provide a robust chronostratigraphy. In addition, a geophysical survey (electric resistivity tomography (ERT) method) was conducted to reveal the sub-surface morphology in the coring area. The results reveal that a freshwater lake existed from ca. 2100–2000 BC to ca. 1200–1100 BC, which subsequently became swampland until ca. 700 BC. A lake retreat is identified at ca. 1200–1000 BC and can be interpreted as resulting from the 3.2 cal kyr BP rapid climate change (RCC) dry event, observed elsewhere in the Eastern Mediterranean. Subsequently, from the 7th to the 5th century BC, there was the input of detrital material and fluvial dynamics prevailed until at least Roman times. The origin of the lake and its disappearance are discussed in the context of regional climate change and local tectonic activity, without excluding possible human influences. We also reconstruct the vegetation history for the period from the Late Minoan to the Early Archaic period. Pollen analysis reveals a Mediterranean maquis landscape dominated by Olea, together with hygrophilous vegetation, and highlights a clear transition from limnic to swampy environmental conditions around 1100 BC. The pollen sequence is also important for assessing the impact of the 3.2 cal. kyr BP RCC event and for assessing the possibility of an abrupt discontinuity in human activity around Phaistos after the demise of the Minoan Civilization.
Measuring the Immeasurable Corporate Reputation

Published: May 2018

Research on any topic seems incomplete till the time a standardized measure for it is not evolved. Measuring intangible assets seems to be a challenging core for the financial academia. More specifically, assigning value to company’s reputation is subjective which confound researchers around the globe. Despite prolific research into this issue, its measurement still baffles the scholars, practitioners, and managers. Although large number of survey methods (like Fortune Most Admired Companies [FMAC] list) have been used extensively, but certain serious limitations of these methods, finally paved way for quantitative tools to measure corporate reputation. An endeavour has been made through current study to compile the efforts of various researchers, who developed proxies for measuring corporate reputation. Reputation of 500 Indian companies constituting BSE 500 index has been measured using six proxies, and Spearman correlation is computed among these proxies. It is interesting to observe that Indian companies are able to maintain their reputation over the years. The findings of the study clearly reveal that reputation research still lacks a concrete measurement. It is high time for the accounting standard setters to devise a framework for measuring and reporting corporate reputation as it has been widely acclaimed as an indispensable asset.

Background and Aim. This work aims to realize a serious game called “Medius” based on criteria of decision support to present a new mean of communication between the tutor and the autistic child in the form of a playful serious game, and in a purely educational frame. Two methods of communication and learning are involved in Medius: Picture Exchange Communication System “PECS” and Applied Behavior Analysis “ABA” to guarantee an effective apprenticeship for autistic children without taking into account their types of autism. This game is retroactive and will be adapted according to the individual levels of each player.

Result. Thanks to the obtained information we were able to know the preferences, the habits and the characters of the autistic children involved in the experiment.

Conclusion. This work is very useful for a targeted apprenticeship and personalized to each player ( autistic child) and also represents a mean of communication between the tutor and the autistic child seen the difficulty of the exchanges of the information and the communication which reign in the world of the children affected by the pervasive developmental disorders “PDD”.
