Implications of Nonlocal Transport and Conditionally Averaged Statistics on Monin–Obukhov Similarity Theory and Townsend’s Attached Eddy Hypothesis
Authors: Li Qi , Gentine Pierre , Mellado Juan Pedro , McColl Kaighin A.
Published: July 2018

According to Townsend’s hypothesis, so-called wall-attached eddies are the main contributors to turbulent transport in the atmospheric surface layer (ASL). This is also one of the main assumptions of Monin–Obukhov similarity theory (MOST). However, previous evidence seems to indicate that outer-scale eddies can impact the ASL, resulting in deviations from the classic MOST scaling. We conduct large-eddy simulations and direct numerical simulations of a dry convective boundary layer to investigate the impact of coherent structures on the ASL. A height-dependent passive tracer enables coherent structure detection and conditional analysis based on updrafts and subsidence. The MOST similarity functions computed from the simulation results indicate a larger deviation of the momentum similarity function ϕ m from classical scaling relationships compared to the temperature similarity function ϕ h. The conditional-averaged ϕ m for updrafts and subsidence are similar, indicating strong interactions between the inner and outer layers. However, ϕ h conditioned on subsidence follows the mixed-layer scaling, while its updraft counterpart is well predicted by MOST. Updrafts are the dominant contributors to the transport of momentum and temperature. Subsidence, which comprises eddies that originate from the outer layer, contributes increasingly to the transport of temperature with increasing instability. However, u′ of different signs are distributed symmetrically in subsidence unlike the predominantly negative θ′ as instability increases. Thus, the spatial patterns of u′ w′ differ compared to θ′ w′ in regions of subsidence. These results depict the mechanisms for departure from the MOST scaling, which is related to the stronger role of subsidence.
The “Bag Breakup” Spume Droplet Generation Mechanism at High Winds. Part II: Contribution to Momentum and Enthalpy Transfer

Published: July 2018

In Part I of this study, we used high-speed video to identify “bag breakup” fragmentation as the dominant mechanism by which spume droplets are generated at gale-force and hurricane wind speeds. We also constructed a spray generation function (SGF) for the bag-breakup mechanism. The distinctive feature of this new SGF is the presence of giant (~1000 μm) droplets, which may significantly intensify the exchange between the atmosphere and the ocean. In this paper, Part II, we estimate the contribution of the bag-breakup mechanism to the momentum and enthalpy fluxes, which are known to strongly affect the development and maintenance of hurricanes. We consider three contributions to the spray-mediated aerodynamic drag: 1) “bags” as obstacles before fragmentation, 2) acceleration of droplets by the wind in the course of their production, and 3) stable stratification of the marine atmospheric boundary layer due to levitating droplets. Taking into account all of these contributions indicates a peaking dependence of the aerodynamic drag coefficient on the wind speed, which confirms the results of field and laboratory measurements. The contribution of the spray-mediated flux to the ocean-to-atmosphere moist enthalpy is also estimated using the concept of “reentrant spray,” and the equation for the enthalpy flux from a single droplet to the atmosphere is derived from microphysical equations. Our estimates show that a noticeable increase in the enthalpy exchange coefficient at winds exceeding 30–35 m s−1 is due to the enhancement of the exchange processes caused by the presence of giant droplets originating from bag-breakup fragmentation.
Impacts of Modifications to a Local Planetary Boundary Layer Scheme on Forecasts of the Great Plains Low-Level Jet Environment
Authors: Jahn David E. , Gallus William A.
Published: July 2018

The Great Plains low-level jet (LLJ) is influential in the initiation and evolution of nocturnal convection through the northward advection of heat and moisture, as well as convergence in the region of the LLJ nose. However, accurate numerical model forecasts of LLJs remain a challenge, related to the performance of the planetary boundary layer (PBL) scheme in the stable boundary layer. Evaluated here using a series of LLJ cases from the Plains Elevated Convection at Night (PECAN) program are modifications to a commonly used local PBL scheme, Mellor–Yamada–Nakanishi–Niino (MYNN), available in the Weather Research and Forecasting (WRF) Model. WRF forecast mean absolute error (MAE) and bias are calculated relative to PECAN rawinsonde observations. The first MYNN modification invokes a new set of constants for the scheme closure equations that, in the vicinity of the LLJ, decreases forecast MAEs of wind speed, potential temperature, and specific humidity more than 19%. For comparison, the Yonsei University (YSU) scheme results in wind speed MAEs 22% lower but specific humidity MAEs 17% greater than in the original MYNN scheme. The second MYNN modification, which incorporates the effects of potential kinetic energy and uses a nonzero mixing length in stable conditions as dependent on bulk shear, reduces wind speed MAEs 66% for levels below the LLJ, but increases MAEs at higher levels. Finally, Rapid Refresh analyses, which are often used for forecast verification, are evaluated here and found to exhibit a relatively large average wind speed bias of 3 m s−1 in the region below the LLJ, but with relatively small potential temperature and specific humidity biases.
Education, Smoking, and Cohort Change: Forwarding a Multidimensional Theory of the Environmental Moderation of Genetic Effects
Authors: Wedow Robbee , Zacher Meghan , Huibregtse Brooke M. , Mullan Harris Kathleen , Domingue Benjamin W. , Boardman Jason D.
Published: July 2018

Sociologists interested in the effects of genes on complex social outcomes claim environmental conditions structure when and how genes matter, but they have only studied environmental moderation of genetic effects on single traits at a time (gene-by-environment interactions). In this article, we propose that the social environment can also transform the genetic link between two traits. Taking the relationship between educational attainment and smoking as an exemplary case, we use genome-wide methods to examine whether genetic variants linked to education are also linked to smoking, and whether the strength of this relationship varies across birth cohorts. Results suggest that the genetic relationship between education and smoking is stronger among U.S. adults born between 1974 and 1983 than among those born between 1920 and 1959. These results are supported by replication in additional data from the United Kingdom. Environmental conditions that differ across birth cohorts may result in the bundling of genetic effects on multiple outcomes, as anticipated by classic cohort theory. We introduce genetic correlation-by-environment interaction [(rG)xE] as a sociologically-informed model that will become especially useful as data for more well-powered analyses become available.
The Ethics of Interstitial and Cesarean Scar Ectopic Pregnancies
Authors: Buskmiller Cara
Published: July 2018

Catholic bioethicists have extensively addressed extrauterine tubal pregnancies, which represent the great majority of ectopic pregnancies. However, additional management options have been developed for the other 7–10 percent of ectopic pregnancies. Using two cases of interstitial pregnancy and two cases of cesarean scar pregnancy (CSP) seen at a Catholic tertiary care center, this article discusses options including expectant management, systemic methotrexate, intragestational methotrexate, intragestational potassium chloride, uterine artery embolization, dilation and curettage (D&C), vasopressin use, cornuostomy, cornual wedge resection, CSP evacuation, CSP scar excision, CSP salvage, and hysterectomy. Cornual wedge resection, vasopressin use, and CSP scar excision are morally acceptable; less clearly licit are aspiration of gestational sac contents, cornuostomy, gestational excision for CSPs, and methotrexate. Certainly illicit are any techniques leading to direct abortion such as D&Cs on live embryos or fetuses, double-balloon catheter placement, and use of potassium chloride.

Summary: An ectopic pregnancy is any pregnancy outside the uterus. These are dangerous because the pregnancy can burst out of its abnormal location and cause life-threatening internal bleeding. Most are in the part of the fallopian tube outside the uterus, but there are other types, including interstitial pregnancies (located in the part of the tube tunneling through the uterine wall) and cesarean scar pregnancies (buried in the uterine scar where the cut for a C-section was made). This article lists the ways that physicians prevent women from dying from interstitial and cesarean scar pregnancies and proposes which treatments are morally acceptable.
Detention under section 136: Why is it increasing?
Authors: Loughran Matthew
Published: July 2018

There has been a significant increase in the use of section 136 of the Mental Health Act 1983 in England and Wales, particularly over the past 10 years, but the reasons for this increase remain unclear. This paper presents a history of English mental-health legislation and the current evidence relating to the use of section 136. It suggests that changing police attitudes, socio-economic factors and diminished resources amongst both the police and mental-health services may have contributed towards its increase. The strain placed on health services may have also resulted in a greater reliance on the police force as an access point to NHS care and could result in the inappropriate use of section 136. With the principle of the ‘least restrictive option’ at the heart of the Mental Health Act, this advocates the need for reform.
Association Between 5-Star Nursing Home Report Card Ratings and Potentially Preventable Hospitalizations
Authors: Ryskina Kira L. , Konetzka R. Tamara , Werner Rachel M.
Published: July 2018

Nursing homes’ publicly reported star ratings increased substantially since Centers for Medicare & Medicaid Services’s Nursing Home Compare adopted a 5-star rating system. Our objective was to test whether the improvements in nursing home 5-star ratings were correlated with reductions in rates of hospitalization. We hypothesized that increased attention to 5-star star ratings motivated nursing homes to make changes that improved their star ratings but did not affect their hospitalization rate, resulting in a weakened association between ratings and hospitalizations. We used 2007-2010 Medicare hospital claims and nursing home clinical assessment data to compare the correlation between nursing home 5-star ratings and hospitalization rates before versus after 5-star ratings were publicly released. The correlation between the rate of hospitalization and a nursing home’s 5-star rating weakened slightly after the ratings became publicly available. This decrease in correlation was concentrated among patients receiving post-acute care, who experienced relatively more hospitalizations from best-rated nursing homes. The improvements in nursing home star ratings after the release of Medicare’s 5-star rating system were not accompanied by improvements in a broader measure of outcomes for post-acute care patients. Although this dissociation may be due to better matching of sicker patients to higher-quality nursing homes or superficial improvements by nursing homes to increase their ratings without substantial investments in quality improvement, the 5-star ratings nonetheless became less meaningful as an indicator of nursing home quality for post-acute care patients.
After the Gold Rush: Cleaning Up after Steve Fuller’s Theosis
Authors: Lynch William T.
Published: July 2018

Remedios and Dusek have provided a useful contextualization of Steve Fuller’s recent work in social epistemology. While they have provided some good criticisms of some of Fuller’s new ideas, they fail to provide a systematic critique of Fuller’s retreat from a naturalistic and materialist social epistemology for one embracing transhumanism, intelligent design, and the proactionary imperative. An alternative approach is developed, drawing on Fuller’s early work and incorporating recent work on our biological and cultural evolution as a species.
Proton conducting diazanium hydrogen phosphate/poly(vinyl alcohol) electrolytes: Transport, electrical, thermal, structural, and optical properties
Authors: Naik Jagadish , Bhajantri RF , Rathod Sunil G , Naik Ishwar
Published: July 2018

Proton conducting solid polymer electrolyte films, which are composed of diazanium hydrogen phosphate (DAHP) and poly(vinyl alcohol) (PVA), were prepared by a solution casting method. The prepared films were characterized by ultraviolet-visible, X-ray diffraction, and differential scanning calorimetry. The optical activation energy and band gap increases with increase in DAHP content in PVA. The direct current (DC) and alternating current (AC) conductivity studies have been carried out using an impedance analyzer. The sample containing 15 wt% DAHP shows highest AC conductivity of the order of 10−4 S cm−1 and DC conductivity about 4.27 × 10−7 S cm−1 at ambient conditions. The crystallinity has decreased and glass transition temperature ( T g) has increased with increase in DAHP content. The Williams–Landel–Ferry and Vogel–Fulcher–Tamman equations were used to calculate dynamic fragility ( m) and apparent activation energy ( E g) from T g values. The Rice and Roth model was successfully applied to determine the transport parameters for DAHP/PVA electrolytes. This article mainly focused on understanding the contribution of different parameters to conductivity phenomenon in solid polymer electrolytes.
Possible future impacts of elevated levels of atmospheric CO2 on human cognitive performance and on the design and operation of ventilation systems in buildings
Authors: Lowe Robert J , Huebner Gesche M , Oreszczyn Tadj
Published: July 2018

This paper brings together a rapid evidence assessment of impacts of elevated CO2 concentrations on human cognition with IPCC projections of atmospheric CO2 concentration by the end of the present century, and an analysis of potential consequences of increased atmospheric CO2 concentrations for ventilation systems in buildings and other enclosed spaces. Whilst only limited research has been done on the effect of CO2 on cognition (as opposed to air quality in general), half of the studies reviewed indicate that human cognitive performance declines with increasing CO2 concentrations. Hence, given the likelihood of increasing atmospheric CO2 concentration by the end of the 21st century, direct impacts of anthropogenic CO2 emissions on human cognitive performance may be unavoidable. Attempts to minimise these direct impacts are likely to result in significant indirect impacts on the engineering of ventilation systems and associated energy use in all enclosed spaces including buildings and transport systems.

Practical application: This paper concerns what may well be one of the most important long-term drivers of the design, management, operation and regulation of ventilation systems over the remainder of the 21st century. It will be relevant to professionals, particularly at senior levels in the building industry.
Self-Selected and Prescribed Intensity Exercise to Improve Physical Activity Among Inactive Retirees
Authors: Yang Zhinan , Petrini Marcia A.
Published: July 2018

A randomized controlled study explored the effects of two intensity-oriented exercise interventions on affect to exercise and physical activity behavior. Inactive retirees finished the 12-week group-based exercise intervention and 3-month telephone follow-up with 27 in self-selected intensity group and 26 in prescribed intensity group. Repeated measures of daily step counts (measured by Yamax pedometers), positive and negative affect to exercise, weight, height, waist circumference, and blood pressure were done at baseline, postintervention, and 3-month follow-up. Increased daily step counts and positive affect, and reduced body mass index, waist circumference, blood pressure of both groups, and negative affect of self-selected intensity group were found at different measuring times. Although self-selected intensity group had no significantly different daily step counts from prescribed intensity group, the former had a more positive and less negative affect to exercise. Findings suggest that future exercise programs use self-selected intensity exercise programs to improve pleasure affect to exercise.
Reduced peripheral blood regulatory B cell levels are not associated with the Expanded Disability Status Scale score in multiple sclerosis
Authors: Guo Shujun , Chen Qingqing , Liang Xiaoli , Mu Mimi , He Jing , Fang Qiang , Song Chuanwang , Sang Daoqian
Published: July 2018

Objective

To investigate levels of regulatory B (Breg) cells, plasma cells, and memory B cells in the peripheral blood, and interleukin (IL)-10 in the serum of multiple sclerosis (MS) patients, and to determine the correlation between Breg cell levels and the Expanded Disability Status Scale (EDSS) score.

Methods

Levels of Breg cells, plasma cells, and memory B cells in the peripheral blood of 12 MS patients were measured using flow cytometry. IL-10 serum levels were measured by enzyme-linked immunosorbent assay. The correlation between Breg cell levels and MS EDSS score was measured using Pearson’s correlation coefficient.

Results

Compared with healthy controls, MS patients had decreased levels of CD19+CD24hiCD38hi Breg cells in their peripheral blood and reduced serum levels of IL-10; however, the ratios of CD19+CD27hiCD38hi plasma cells and CD19+CD27+CD24hi memory B cells to total B cells did not differ significantly between healthy controls and MS patients. CD19+CD24hiCD38hi Breg cell levels in the peripheral blood of MS patients were not significantly correlated with MS EDSS score.

Conclusion

Peripheral blood CD19+CD24hiCD38hi Breg cell levels and serum IL-10 levels were reduced in MS patients compared with controls, but Breg cell levels were not correlated with MS EDSS score.
Clinicopathological features of pediatric renal biopsies in the plateau regions of China
Authors: Wang Nini , Zhu Tingting , Tao Yuhong
Published: July 2018

Objective

This study aimed to analyze the clinicopathological features of pediatric renal biopsies from plateau regions of China.

Methods

Clinicopathological features of pediatric renal biopsies were compared between plateau and non-plateau regions in patients who were admitted to West China Second University Hospital, Sichuan University between April 2001 and March 2017. Patients were children younger than 18 years.

Results

The proportion of primary glomerular disease in the plateau group was lower than that in the non-plateau group (45.56% vs 62.09%, respectively). In the plateau group, IgA nephropathy (IgAN) was the major primary glomerulonephritis (GN) pathology. IgAN accounted for 36.54% and 21.63% of GN cases with nephrotic syndrome and hematuria, respectively. Henoch-Schönlein purpura nephritis was the most common secondary GN in both groups. The proportion of hepatitis B virus-associated GN was higher and that of lupus nephritis was lower in the plateau group than in the non-plateau group.

Conclusions

There are differences in renal pathological types between children in plateau regions and those in non-plateau regions. Among children in plateau regions, IgAN and Henoch-Schönlein purpura nephritis were the most common kidney diseases.
Histopathologic differentiation as a prognostic factor in patients with carcinoma of the hepatopancreatic ampulla of Vater
Authors: Radojkovic Milan , Stojanovic Miroslav , Radojković Danijela , Jeremic Ljiljana , Mihailovic Dragan , Ilic Ivan
Published: July 2018

Objective

Periampullary carcinomas are a group of neoplasms with variable histopathology that originate from the anatomical junction of different epithelial types including the bile duct, pancreatic duct, and duodenal mucosa. This study was performed to determine whether the histopathologic type of these tumors should be considered an independent prognostic factor.

Methods

We analyzed the specimen histopathology of 37 patients who underwent radical cephalic pancreatoduodenectomy for carcinoma of the ampulla of Vater during a 5-year period. We excluded patients with other tumors with an indication for Whipple’s procedure and those in whom R0 resection was not achieved.

Results

The carcinomas of the hepatopancreatic ampulla were intestinal in 23 (62%) patients, pancreatobiliary in 13 (35%), and mixed type in 1 (3%). The analysis demonstrated significantly more advanced local tumor spread, a more aggressive lymph node metastasizing pattern, and more frequent lymphatic and perineural invasion in patients with pancreatobiliary than intestinal and mixed type tumors.

Conclusion

Pancreatobiliary type of ampullary carcinoma is associated with a poorer prognosis than intestinal and mixed types because of its more aggressive behavior. Histopathology should be regarded as an independent predictor of survival and may have therapeutic and prognostic implications for patients.
The Effect of Transient Location on the Resolution of Bistable Visual and Audiovisual Motion Sequences
Authors: Adams Kelsey L. , Grove Philip M.
Published: July 2018

We examined the attention and inference accounts of audiovisual perception using the stream/bounce display, a visual stimulus wherein two identical objects move toward each other, completely superimpose, then move apart. This display has two candidate percepts: stream past each other or bounce off each other. Presented without additional visual or auditory transients, the motion sequence tends to yield the streaming percept, but when coupled with a tone or flash at the point of coincidence, the response bias flips toward bouncing. We explored two competing accounts of this effect: the attentional hypothesis and the inference hypothesis. Participants watched a series of motion sequences where a transient, when present, occurred at the moment of coincidence either colocalised with the motion sequence (congruent presentation) or on the opposite side of the display (incongruent presentation). Assuming the spotlight or zoom lens metaphor, an attentional account predicts that incongruent presentations should be associated with a higher percentage of bouncing responses than congruent presentations, while the inferential account predicts the opposite effect. No effect was found for tone-only trials. However, in trials containing a visual transient, results showed higher proportions of bounce responses within congruent over incongruent presentations, favouring the inference hypothesis over a spotlight or zoom lens attentional account.
What’s wrong with healthy rivers? Promise and practice in the search for a guiding ideal for freshwater management
Authors: Blue Brendon
Published: July 2018

It is easy to talk of improving river condition. It is more difficult to pin down exactly what this means. Emerging from ecology, the concept of river health presented an attempt to provide a broad framework for freshwater management incorporating both natural and human values. Initially criticised as subjective and unscientific, river health was nevertheless mainstreamed through being rendered quantifiable. Tracing the (re)definition of river health from a holistic but hazy ethic of environmental care to prescriptive indicators for intervention, I examine how common-sense understandings of river condition were first challenged by, and then incorporated within, the scholarly and political project of river health. Arguing that the search for objectivity entrenched assumptions that naturalness was both desirable and attainable, I explore the potential value of a reimagined, revitalised river health as a constructive platform for renegotiating and broadening what matters for freshwater.
Exploring Growth Trajectories of Informal and Formal Mathematics Skills Among Prekindergarten Children Struggling With Mathematics
Authors: Namkung Jessica M. , Peng Peng , Goodrich J. Marc , Molfese Victoria
Published: July 2018

Growth in two subscales, Informal and Formal Mathematics Skills, of the Test of Early Mathematics Abilitity–3 (TEMA-3) was explored in a sample of 281 children. Children were identified as either typically developing (TYP; n = 205) or having mathematics difficulties (MD; n = 76) based on their total TEMA-3 score at the end of prekindergarten. Their average level of informal and formal mathematics skills, growth rate over time, and rate of acceleration of growth were estimated using conventional growth modeling while controlling for the effects of gender. Results indicated that children with MD had significantly lower informal and formal mathematics knowledge than did TYP children at the end of kindergarten. However, for informal mathematics skills, children with MD grew at a significantly faster rate than did TYP children, and the rate of acceleration was also significantly faster for children with MD. In contrast, both the rate of growth and acceleration of growth in formal mathematics skills were significantly faster for TYP children than they were for children with MD. Implications for early MD identification and interventions are discussed.
Discourses Reproducing Gender Inequities in Hospice Palliative Home Care
Authors: Sutherland Nisha , Ward-Griffin Catherine , McWilliam Carol , Stajduhar Kelli
Published: July 2018

Background

As home is a site where gendered attitudes, beliefs, and practices are reproduced, it is imperative that policies and practices promote gender equity in end-of-life care at home.

Purpose

The purpose of this study was to critically analyze gender relations in the sociopolitical context of hospice palliative home care.

Methods

Using a critical feminist perspective, we examined gender relations between and among clients with cancer, their family caregivers, and nurses in hospice palliative home care. Ethnographic methods of in-depth interviews (n = 25), observations of home visits (n = 9), and review of documents (n = 12) were employed to expose gender (in)equities.

Findings

This critical analysis sheds light on institutional discourses that reproduce gender inequities: discourses of difference and denial; discourses of individuality, autonomy, and choice; and discourses of efficiency, objectivity, and rationality. Although gender was discounted, these neoliberal discourses reinforced traditional gender relations.

Discussion

Neoliberal discourses frame health and health-care experiences as resulting primarily from individual behaviors and biomedical factors, permitting health-care providers and policy makers to overlook power relations and the sociopolitical forces that obscure gender inequities. A critical perspective is needed to consider how social structures significantly shape everyday gendered experiences in hospice palliative home care.
Forcible Rape and Adolescent Friendship Networks
Authors: Tomlinson Tiffaney A. , Mears Daniel P. , Turanovic Jillian J. , Stewart Eric A.
Published: July 2018

Studies have found that sexual victimization can adversely affect an adolescent’s psychological well-being, physical health, and behavior. Little is known, however, about how friendships are influenced by such victimization. Drawing on research on sexual violence and the salience of peers among adolescents, the current study extends prior work by examining the effects of forcible rape on adolescent social networks. Using a subsample of females from the National Longitudinal Study of Adolescent to Adult Health ( N = 4,386), the study employs multivariate regression analyses to estimate the effects of youth forcible rape on the popularity, centrality, and density of adolescent friendship networks and to determine whether depression and attachment to others (e.g., to friends and to school) mediate these effects. The analyses indicated that forcible rape was associated with a decrease in the popularity and centrality of females within their friendship networks; however, no effect on the density of these networks was identified. In addition, forcible rape effects on popularity and centrality were partially mediated by depression and social attachments. The results suggest that forcible rape may adversely affect adolescent females’ levels of popularity and centrality within their friendship networks. Combined with prior research, the results indicate that the harmful effects of rape have the potential to extend across diverse domains, including social relationships. This possibility suggests that services and assistance to female adolescents may be useful in navigating these relationships after victimization. It suggests, too, that potential benefits that may arise from interventions that educate adolescents—victims and nonvictims alike—about the challenges that victims of sexual violence experience.
Palestinian Adolescents’ Prolonged Exposure to Political Violence, Self- Esteem, and Post-Traumatic Stress Symptoms
Authors: Haj-Yahia Muhammad M. , Greenbaum Charles W. , Lahoud-Shoufany Laila
Published: July 2018

The goal of this study was to understand the relation between adolescents’ long-term exposure to political violence (EPV) and post-traumatic stress symptoms (PTSS). We examined the relations among EPV, PTSS, and self-esteem to determine whether self-esteem could buffer the effects of EPV on PTSS. A systematic cluster random sample of 2,934 Palestinian adolescent boys and girls in the West Bank area of the Palestinian Authority and in East Jerusalem participated in a study using a self-administered questionnaire. Multiple regression analysis showed that the more Palestinian youth were exposed to political violence during the last year and during previous years, the more they exhibited PTSS and its three manifestations, that is, avoidance, intrusion, and arousal. In addition, EPV showed effects on PTSS after controlling for sociodemographic variables and self-esteem. Girls and residents of the West Bank reported more PTSS than boys and residents of East Jerusalem, respectively. Higher levels of EPV correlated with lower levels of self-esteem, and children with relatively low self-esteem were likely to report more PTSS than children with high self-esteem. Hence, the correlations between participants’ EPV and some of the PTSS were found to be partially dependent on the levels of their self-esteem, indicating moderating and mediating effects for self-esteem on the relation between degree of EPV and PTSS. The limitations of the study and implications for future research are discussed.
Functional upgrading fundamental and performance upgrading priority ranking of adaptable-function products
Authors: Tu Q , Deng Y-M , Nee AYC , Lu WF
Published: July 2018

Excellence in function and performance is one of the key reasons for a product to sustain its market competitiveness. Upgrading of products, including those of the adaptable-function products, is necessary to ensure their market attractiveness. Current research that is specifically on upgrading of adaptable-function products is lacking. To this end, this paper attempts to study both functional aspect and performance aspect of upgrade design of this kind of products. For the former, the study focuses on some fundamental issues of functional upgrading relevant to the upgrading type, where an analogy-based functional upgrading strategy is proposed. The proposed work is illustrated by the functional upgrading of an electric drill design case. For the latter, the study focuses on how to evaluate the upgrading priority, for which a number of performance attributes to be upgraded are specified. For this purpose, the technology potentials for enabling the upgrade design (which should be maximized) and the influence caused by the upgrading (which should be minimized) are first studied. Based on technology potentials and upgrading influence, the priority ranking is evaluated to help the designer making performance upgrading decisions. Finally, a case study of upgrading a multifunction machine tool is presented, which demonstrates the feasibility of the proposed evaluation method. With the help of the established upgrading design prototype and the strategy of upgrading priority ranking guidelines, the designers can get the relevant design support during their upgrade design process.
Finite element analysis of the impact of screw insertion distal to the trochanter minor on the risk of iatrogenic subtrochanteric fracture
Authors: Sensoz Ersin , Özkal Fatih Mehmet , Acar Volkan , Cakir Ferit
Published: July 2018

Iatrogenic subtrochanteric fractures are rarely encountered after cannulated screw fixation of femoral neck fractures; however, when they do occur, there can be several complications. Many orthopedic surgeons have concerns about the potential for iatrogenic subtrochanteric fractures after screw fixation distal to the trochanter minor; therefore, some surgeons are typically reluctant to perform this procedure. This study focused on the risk of an iatrogenic subtrochanteric fracture after treating femoral neck fractures with cannulated screws. The main purpose of the study was to understand iatrogenic subtrochanteric fractures and evaluate the effects on these fractures of an inverted triangular–shaped configuration for placement of the cannulated screws. A femur bone with an femoral neck fracture at a 40° incline to the horizontal plane was generated along with a representation of a three-dimensional finite element model, and three inverted triangular–shaped configurations for placement of the cannulated screws were investigated using finite element analyses. Statistical results indicated that the occurrence risk of ISF increases when the screw is located distal to the trochanter minor. Moreover, the risk of occurrence of intertrochanteric fracture increases when the screw is located medial to the trochanter minor because of local concentrated stress on the surface of the screw canals. To avoid the vulnerability of the subtrochanteric region, it was found that proximal placement of the screws using the inverted triangular–shaped configuration could yield better results. In addition, the results of this study provide suggestions on improved screw configurations.
Mental disorders in commentaries by the late medieval theologians Richard of Middleton, John Duns Scotus, William Ockham and Gabriel Biel on Peter Lombard’s Sentences
Authors: Hirvonen Vesa
Published: July 2018

In their commentaries on the Sentences, Richard of Middleton, John Duns Scotus, William Ockham and Gabriel Biel reflect whether mentally-disturbed people can receive the sacraments (Baptism, Eucharist, confession, marriage) and fulfil juridical actions (make a will or take an oath). They consider that the main problem in ‘madmen’ in relation to the sacraments and legal actions is their lack of the use of reason. Scotus and Ockham especially are interested in the causes of mental disorders and the phenomena which happen in madmen’s minds and bodies. In considering mental disorders mostly as naturally caused psycho-physical phenomena, Scotus and Ockham join the rationalistic mental disorder tradition, which was to become dominant in the early modern era and later.

We present a case of scleroderma overlap syndrome with systemic lupus erythematosus (SLE) including complications of both scleroderma renal crisis and lupus nephritis. Our patient was initially diagnosed with undifferentiated connective tissue disease in 1996. A diagnosis of scleroderma was made in 2010 after she developed scleroderma renal crisis. She remained stable until 2016, when she presented with Salmonella bacteremia, renal failure, nephrotic range proteinuria and microscopic hematuria. Laboratory findings were consistent lupus with positive ds-DNA, hypocomplementemia and repeat renal biopsy showed lupus nephritis.
From present to presentation: A philosophical critique of Hartmut Rosa’s “situational identity”
Authors: D'Ambrosio Paul J
Published: July 2018

Hartmut Rosa classifies modernity and late modernity in terms of the “speeding up” or “acceleration” of society. External institutions require constant development in order to maintain themselves, including material growth, technological acceleration, and cultural innovation. As has been widely noted, this is reflected internally by subjects whose thoughts and attitudes revolve around obsessive calculation, teleological thinking, and desires for Promethean-like control over nature, themselves, and their social environments. Coupled with an increase in functional differentiation, which has fragmented and shrunk once stabilizing and meaning-conferring social roles, Rosa argues that the logic of growth results in subjects whose identity is “situationally” determined. These subjects continually jockey between disparate role-based identities according to whatever situation they happen to be in at a given moment. Drawing on Erving Goffman’s research on self-presentation and the philosophy of genuine pretending as developed by Hans-Georg Moeller and Paul D’Ambrosio, I will argue that situational identity is even more complex than Rosa has demonstrated. People living in late modern societies construct identities that are multifarious and incongruent in terms of not only roles, but also the very “paradigms of identity”—e.g. sincerity, individualism, authenticity, irony—through which roles are adopted. Problematically, outdated models of identity, based largely on the sincerity and its associated conceptions of the “self” and ethics, continue to dominate, leading to insoluble tensions between various socially-established identities. I will present “profilicity,” the understanding of identity based on profile construction with an acute awareness of the second-order observation, as a paradigm that is increasingly important in today’s world.
English-speaking and Educated Female Domestic Workers in Contemporary India
Authors: Grover Shalini
Published: July 2018

This article foregrounds a labour market for English-speaking and educated female domestic workers and their Western expatriate employers. Many women in this anthropological study had left office jobs and institutional environs connoting dignity to take up employment in Euro-American households performing what is widely perceived as low-status work. Using the narratives of domestic workers, this article scrutinizes motivations for opting for a stigmatized occupation and finds women’s accounts to be multilayered and provocative, thereby challenging established generalizations. In the intimate space of the expatriate household, these female workers diligently perform the tasks of an ‘all-rounder’ that represents a new managerial role in globalizing India. As part of expanding niche labour markets, the article highlights how these roles demand eclectic skill sets, professionalism, certified training, transnational experience and gender-specific expertise. Nonetheless, a key leitmotif is how domestic service with expatriates’ remains embedded in power relations and class-race hierarchies. In developing the anthropology of domestic labour, this article illuminates the continuation of persistent inequality and stratification in a locally functioning transnational labour market.

Cancer is a complex disease involving genetic and phenotypic changes. Several single nucleotide polymorphisms (SNPs) have been associated with the risk of breast cancer development in women; however, little is known regarding their influence on canine mammary tumor risk. We assessed the influence of SNPs in genes related to human breast cancer susceptibility, with respect to the risk of development of mammary tumors in dogs. Sixty-seven canine SNPs in proto-oncogenes, tumor suppressor genes, genes involved in DNA repair, and in hormonal metabolism were evaluated in 212 bitches with mammary tumors and in 161 bitches free of mammary neoplasia. A significant association with mammary neoplasia risk was identified for 2 SNPs in RAD51 ( rs23623251 and rs23642734) and one SNP in the STK11 gene ( rs22928814). None of the other SNPs were related to the risk of mammary tumor development. The identification of genetic profiles associated with risk of mammary neoplasia is of great importance, supporting the implementation of specific clinical management strategies in high-risk animals.
From Patient to Provider: The Lived Experience of Pediatric Oncology Survivors Who Work as Pediatric Oncology Nurses
Authors: Conte Teresa M.
Published: July 2018

There is little known about the experiences of former pediatric oncology patients that are currently working as pediatric oncology nurses. Literature reviews yielded no direct research studies involving this group of nurses. The purpose of this phenomenological study was to describe the experiences of these former oncology patients that are now oncology nurses. Eleven pediatric oncology nurses were interviewed for this study, and the following themes emerged: Awe and Awkwardness, Guilt and Gratitude, Sharing My Story, Wanting to Remember/Wanting to Forget, and Past Treatment/Current Challenges. The results of this study demonstrate the unique challenges these survivors face as they transition into their professional roles. Information about these nurses’ experiences is important when considering their education and support throughout their careers.
Cross-Validating a Structural Model of Factors Influencing Diabetes Self-Management in Chinese Americans with Type 2 Diabetes

Introduction: The purpose of this study was to cross-validate a structural model depicting the effects of individual and environmental factors on diabetes self-management in Chinese Americans with type 2 diabetes. Methodology: A cross-sectional survey was administered to a convenience sample of 209 Chinese Americans with type 2 diabetes in the Midwest of the United States. Structural equation modeling was used to cross-validate the model fit. Results: Provider–patient communication indirectly influenced self-management via belief in treatment. Knowledge indirectly influenced self-management via belief in treatment and self-efficacy. Social support indirectly influenced self-management via belief in treatment and knowledge. Discussion: This study demonstrated that the structural model, previously tested with Chinese diabetes patients in China, also fits Chinese Americans in the United States with few modifications. The cross-validated model provides a theoretical basis for developing culturally relevant diabetes self-management interventions for Chinese Americans, which may lead to health improvements in this ethnic population.
The Impact of Serious Educational Gameplay on Adolescent Binge Drinking Intentions: A Theoretically Grounded Empirical Examination

Published: July 2018

Introduction. Game On: Know Alcohol, a school-based alcohol education program, aimed to educate adolescents on the harmful effects of (excessive) alcohol consumption. The program included two user-centered serious educational games, Perfect Pour and Dumb Driver. Purpose. To evaluate the objective effect of playing Perfect Pour and Dumb Driver on the key psychosocial determinants of adolescent binge drinking intentions in the context of the theory of reasoned action (TRA). Methods. Data were drawn from four Game On: Know Alcohol program schools ( N = 303 adolescents aged 14-16 years), and two TRA models incorporating four game metrics were analyzed using structural equation modeling. Results. The theoretically guided TRA models linked to gameplay data explained 66% of variance in adolescents’ binge drinking intentions. Average game duration and average score of Perfect Pour were significantly associated with adolescents’ attitudes toward binge drinking, whereas no objective effect on the key psychosocial determinants was observed for Dumb Driver. Conclusions. Inconclusive findings suggest that further research is needed to fully understand how serious educational games may be designed to effectively influence adolescents’ binge drinking intentions. Opportunities to extend theory application beyond evaluation are noted in addition to other opportunities for future research.
A fault diagnosis method combined with compound multiscale permutation entropy and particle swarm optimization–support vector machine for roller bearings diagnosis

Published: July 2018

A method based on compound multiscale permutation entropy, support vector machine, and particle swarm optimization for roller bearings fault diagnosis was presented in this study. Firstly, the roller bearings vibration signals under different conditions were decomposed into permutation entropy values by the multiscale permutation entropy and compound multiscale permutation entropy methods. The compound multiscale permutation entropy model combined the different graining sequence information under each scale factor. The average value of each scale factor was regarded as the final entropy value in the compound multiscale permutation entropy model. The compound multiscale permutation entropy model suppressed the shortcomings of poor stability caused by the length of the original signals in the multiscale permutation entropy model. Validity and accuracy are considered in the numerical experiments, and then compared with the computational efficiency of the multiscale permutation entropy method. Secondly, the entropy values of the multiscale permutation entropy/compound multiscale permutation entropy under different scales are regarded as the input of the particle swarm optimization–support vector machine models for fulfilling the fault identification, the classification accuracy is used to verify the effectiveness of the multiscale permutation entropy/compound multiscale permutation entropy with particle swarm optimization–support vector machine. Finally, the experimental results show that the classification accuracy of the compound multiscale permutation entropy model is higher than that of the multiscale permutation entropy.
