A micro-level analysis of the contagion effect: Evidence from the Kurdish conflict
Authors: Sarigil Zeki
Published: October 2020

The unit of analysis in almost all large-N studies on conflict contagion and diffusion is collective actors, such as states and ethnic groups or movements. Thus, contagion dynamics and processes at the individual level have been neglected. Using original data derived from a public opinion survey, this study examines the micro-level dynamics of contagion in the context of Turkey’s Kurdish conflict. The study suggests that transnational ethnic ties, and in particular, cross-border familial bonds and interactions, facilitate conflict contagion through several strategic and ideational mechanisms. First, transborder familial ties and interactions amplify the demonstration effect of ethnic-kin achievements in contiguous conflict countries. Second, cross-border familial bonds facilitate collaboration between cross-border co-ethnics. Finally, such ties to conflict zones with ethnic kin groups empower pan-ethnic identities. The empirical findings show that Kurds living in Turkey who have close relatives in nearby countries hosting conflicting ethnic-kin groups (i.e. Syria, Iraq, and Iran) have stronger ethnonationalist orientations and claims against the center. However, having close relatives elsewhere (e.g. Europe) does not generate the same impact. The Kurdish case evidences that contagion processes and dynamics might vary substantially across the members of a particular ethnic group. Hence, it is necessary to broaden the conventional focus on collective actors in conflict contagion research and pay greater attention to micro-level variables and factors.

Published: October 2020

Unstable housing and unemployment have been identified as major structural barriers to optimal HIV treatment outcomes among people living with HIV (PLWH). One solution is to provide integrated services that combine medical, employment, housing, and other psychosocial services to address the complex needs of PLWH. This program evaluation reports outcomes of the Foundations for Living program: an integrated employment and housing services program designed for PLWH. Employment and housing outcomes of participants who completed at least one 6-month reassessment were reported by frequency analysis. HIV immune health (CD4 count and viral load) are examined using a matched paired t test. HIV prevention outcomes were assessed by examining changes in the percent of participants with an undetectable viral load. Our findings indicate that among the participants who completed reassessments, 44.8% gained or maintained employment, 86.2% achieved viral load suppression, 75.9% achieved undetectable at the final reassessment. There was no statistical difference between the mean of CD4 count and viral load reported at intake and those reported during the final reassessment. Over half of the participants experienced unstable employment during the program, indicating that significant barriers to employment remain for this population. Implications for rehabilitation counseling practice and research are discussed.

Published: October 2020

The aim of this study was to describe the psychological and physical health needs of informal caregivers in a rehabilitation hospital and explore differences related to informal caregiver and care recipient characteristics. Readiness to engage in health promotion and perspectives on mindfulness meditation were assessed. Informal caregivers ( N = 33) to patients receiving inpatient or outpatient treatment completed the Multidimensional Health Profile screening tools. Readiness to change was assessed using the readiness ruler approach. Almost half of participants (45.5%) had a chronic illness and 18.2% reported that it interferes with daily functioning. Low Positive Health Habits were reported by 43% of participants, and Negative Health Habits were reported by 25%. A subgroup (15%–20%) reported both physical and mental health concerns. A majority of participants indicated it was both very important for them to improve their physical and mental health and felt very confident they could do so. Receptivity to mindfulness meditation was high, with 72.7% reporting an interest. Comprehensive screening and counseling interventions to address the physical and mental health of informal caregivers in physical rehabilitation hospital settings are needed, and information gained from screening could be addressed in interventions delivered by systems-oriented rehabilitation counselors. A mindfulness meditation intervention may be a useful strategy for promoting well-being in this population.
Sequential probability ratio tests: conservative and robust
Authors: Kleijnen Jack P C , Shi Wen
Published: October 2020

Because computers (except for parallel computers) generate simulation outputs sequentially, we recommend sequential probability ratio tests (SPRTs) for the statistical analysis of these outputs. However, until now simulation analysts have ignored SPRTs. To change this situation, we review SPRTs for the simplest case; namely, the case of choosing between two hypothesized values for the mean simulation output. For this case, the classic SPRT of Wald (Wald A. Sequential tests of statistical hypotheses. Ann Math Stat 1945; 16: 117–186) allows general types of distribution, including normal distributions with known variances. A modification permits unknown variances that are estimated. Hall (Hall WJ. Some sequential analogs of Stein’s two-stage test. Biometrika 1962; 49: 367–378) developed a SPRT that assumes normal distributions with unknown variances estimated from a pilot sample. A modification uses a fully sequential variance estimator. In this paper, we quantify the performance of the various SPRTs, using several Monte Carlo experiments. In experiment #1, simulation outputs are normal. Whereas Wald’s SPRT with estimated variance gives too high error rates, Hall’s original and modified SPRTs are “conservative”; that is, the actual error rates are smaller than those prespecified (nominal). Furthermore, our experiment shows that the most efficient SPRT is Hall’s modified SPRT. In experiment #2, we estimate the robustness of these SPRTs for non-normal output. For these two experiments, we provide details on their design and analysis; these details may also be useful for simulation experiments in general.

Published: October 2020

The purpose of this literature review was to examine how language is used to describe and advance culturally-based pedagogy to critically reflect on the language employed in teacher education research. Our intent was to understand the terminology that has moved conversations of equity, diversity, and cultural ways of knowing to the center of urban education research and practice. Findings indicate the discourse of culturally-based pedagogy relies upon: (1) the exploration of the construct of culture, (2) the knowledge of the socio-historical context of specific terminology, and (3) a perspective that discourse is generative and dynamic.

Published: October 2020

Pneumomediastinum is not uncommon in paraquat poisoning and usually results from oesophageal perforation or alveolar rupture in fibrotic lung disease. However, the combined presentation of pneumomediastinum and pneumoperitoneum is a rarity. We recently managed a young patient with paraquat ingestion who developed spontaneous pneumomediastinum. His chest radiograph also showed free air under the right hemidiaphragm. This pneumoperitoneum caused no clinical symptom and resolved spontaneously within a few days without any surgical intervention.
Premarital Education in the Catholic Church: Exploring Retrospective Perceptions of Effectiveness of a Theologically Oriented Program on Relational and Spiritual Outcomes
Authors: Klausli Julia , Gross Christopher
Published: October 2020

The effectiveness of a theology-focused marriage preparation program was tested for a group of Catholic couples (N=200). Each couple had been married for less than five years and participated in the same program. The program covered a variety of topics from communication enhancement to a Catholic theology of marriage, including marriage as a vocation and natural family planning. The study assessed the retrospective perceptions of change for relational and spiritual behaviors and attitudes, in light of these theological and relationship teachings. Couples reported increases in positive thinking about the relationship, deeper understanding of marriage as a vocation, and improved communication. However, the program produced less change in Mass attendance, and NFP practice. Results were moderated by cohabitation history, support of mentor couples and length of marriage. Views of marriage in terms of vocation and increased knowledge of NFP were indirectly linked to higher relationship satisfaction via improved communication.
Occupational change on the dualised Swedish labour market
Authors: Berglund Tomas , Håkansson Kristina , Isidorsson Tommy
Published: October 2020

In the Swedish labour market, recent research has revealed tendencies of both dualisation – implying growth in temporary employment – and polarisation – referring to increased employment in both low- and high-paid jobs, while middle-paid jobs decrease. This study explores the relationships between changes in the occupational structure and the distribution of temporary employment. Using the Labour Force Survey and comparing changes between 2000 and 2015, the study shows a main pattern of upgrading. However, splitting the analysis into permanent and temporary employment, tendencies of polarisation are revealed: growth at the low-paid end consists of temporary employment, while the increase at the high-paid end is mainly of open-ended contracts. Different kinds of temporary contracts matter – on-call employees are more likely to be found at the low end, and project workers at the high end. The study shows increasing precariousness in the lower end of the occupational structure.
A Rare Case of Sinonasal Lymphoepithelial Carcinoma Presented With Clinically Stage IV Disease
Authors: Bonnerup Spencer , Gitau Mark , Shafique Khurram
Published: October 2020

Sinonasal lymphoepithelial carcinoma (SLEC) is an extremely rare malignancy. We present a case of SLEC in a 77-year-old man who presented with nasal congestion and persistent sinusitis. Imaging revealed a large right nasal mass involving right paranasal sinuses along with bulky bilateral cervical lymphadenopathy. In addition, there was a fluorodeoxyglucose avid L1 vertebral lesion. Biopsy of nasal mass and cervical lymph nodes showed syncytial growth of tumor cells in a lymphoplasmacytic background. Immunohistochemical stains showed positivity for pankeratin, CK5/6, epithelial membrane antigen, p40 (focal), and p63 (focal). An Epstein-Barr virus-encoded RNA by in situ hybridization was strong and diffusely positive. Based on these pathologic findings and considering the location of tumor, diagnosis of SLEC was rendered. L1 vertebral body lesion was clinical and radiologically considered to be a metastasis. Correlation with radiology to determine the exact location of tumor is extremely important for correct diagnosis due to its histopathologic similarities with relatively more common undifferentiated type of nasopharyngeal carcinoma. No standard treatment protocol has been established for this tumor yet. To our knowledge, this is first ever report of SLEC presented with clinical stage IV disease.
Do Not Ignore Tuberculosis of the Parotid Gland When Meeting Obvious Infiltration of Neutrophils in a Suspicious Swelling by FNAC
Authors: Yang Fangfang , Wu Mao , Peng Yumeng , Dong Xiaoyan , Ge Yumei
Published: October 2020

Parotid gland tuberculosis constantly results in unnecessary medical examinations and surgery because of its similarities in the presentation to neoplasms of the parotid gland. Although parotid gland involvement is extremely rare even in tuberculosis-endemic countries, accurate diagnosis of this clinical entity is of great significance because tuberculous parotitis can be successfully treated medically without surgical therapy. Fine needle aspiration cytology (FNAC) and molecular identification of the parotid swellings are efficient in making a rapid diagnosis. Herein, we report an early misdiagnosis of malignancy from a renal transplantation patient on long-term immunologic inhibitor therapy, who ultimately proved to have tuberculosis of the parotid gland by FNAC and molecular identification. The aim of this study is to describe and analyze the etiologic characteristics, epidemiology, clinical presentations, diagnostic methods, histopathologic findings, and pathogenic mechanisms of these rare infections.

Published: October 2020

Purpose

The purpose of the study was to adapt and psychometrically evaluate a Japanese language version of the Diabetes Caregiver Activity and Support Scale (D-CASS-J) to be culturally relevant for people with diabetes living in Japan.

Methods

A Japanese translation of the original version of the D-CASS was prepared, corrected, and back-translated. Family caregivers of patients with diabetes mellitus ages ≥65 years who visited the outpatient diabetes clinic of Ise Red Cross Hospital were included. Cronbach’s α coefficients were calculated as an assessment of internal consistency. Exploratory factor analyses were performed to verify construct validity. Hierarchical multiple regression analyses were performed using depression as the dependent variable and D-CASS-J and other variables as explanatory variables. Pearson’s correlation coefficients between D-CASS-J scores and the support burden scale scores were calculated to verify criterion-related validity.

Results

This analysis included 268 subjects. Cronbach’s α coefficient was .86. Factor analyses showed the same single-factor structure as the original version of the D-CASS. Hierarchical multiple regression analyses based on the conceptual model demonstrated construct validity. D-CASS-J scores were significantly correlated with support burden scale scores.

Conclusions

For family caregivers of elderly patients with diabetes in Japan, D-CASS-J can be used as a tool to evaluate difficulties experienced while providing support to patients.
Whether, How, and Why Networks Influence Men’s and Women’s Career Success: Review and Research Agenda
Authors: Woehler Meredith L. , Cullen-Lester Kristin L. , Porter Caitlin M. , Frear Katherine A.
Published: October 2020

Substantial research has documented challenges women experience building and benefiting from networks to achieve career success. Yet fundamental questions remain regarding which aspects of men’s and women’s networks differ and how differences impact their careers. To spur future research to address these questions, we present an integrative framework to clarify how and why gender and networks—in concert—may explain career inequality. We delineate two distinct, complementary explanations: (1) unequal network characteristics (UNC) asserts that men and women have different network characteristics, which account for differences in career success; (2) unequal network returns (UNR) asserts that even when men and women have the same network characteristics, they yield different degrees of career success. Further, we explain why UNC and UNR emerge by identifying mechanisms related to professional contexts, actors, and contacts. Using this framework, we review evidence of UNC and UNR for specific network characteristics. We found that men’s and women’s networks are similar in structure (i.e., size, openness, closeness, contacts’ average and structural status) but differ in composition (i.e., proportion of men, same-gender, and kin contacts). Many differences mattered for career success. We identified evidence of UNC only (same-gender contacts), UNR only (actors’ and contacts’ network openness, contacts’ relative status), neither UNC nor UNR (size), and both UNC and UNR (proportion of men contacts). Based on these initial findings, we offer guidance to organizations aiming to address inequality resulting from gender differences in network creation and utilization, and we present a research agenda for scholars to advance these efforts.
Digital mourning on Facebook: the case of Filipino migrant worker live-in caregivers in Israel
Authors: Babis Deby
Published: October 2020

The practice of mourning on social media, known as digital mourning, has become a worldwide phenomenon. While scholarly attention focuses on manifestations of online grief, there is a dearth of research regarding this process among immigrants. Based on a digital ethnography on Facebook on the Filipino community in Israel, this study inquires how migrant workers construct their mourning on digital networks. Focusing on grief upon death in the host country, two different practices of digital mourning were found. When Filipino live-in caregivers announce the loss of their elderly employers, their personal pain is shared on their own Facebook wall, receiving personal condolence comments. However, when a fellow Filipino migrant worker passes away, the pain is shared in closed community groups on Facebook, which are followed by thousands of condolence comments. This practice creates a communal feeling that can be termed Communal Digital Grief, and differs from the Personal Digital Grief experienced by migrants as a result of the loss of their employer. This study sheds light on two different practices of digital mourning. One appears on the personal Facebook walls of the bereaved and has therapeutic impact, while the other appears on closed Facebook groups and contributes to community building.
Themes and tones of cannabis news reports and legalization outcomes
Authors: Lynch Michael
Published: October 2020

This project analyzed print news articles on cannabis legalization that were published in 2015 ( N = 295) from newspapers across the United States. The following year, 2016, saw more states legalize cannabis for adult use and medical use than before. Therefore, one goal of this research was to investigate the relationship between reports on cannabis legalization and subsequent legal changes that occurred in states that reformed their cannabis laws. Findings reveal that cannabis legalization issues are reported in the media with tones that favor, oppose, or are neutral toward cannabis legalization. Overall, cannabis legalization stories were reported with a neutral tone. Additionally, arguments about whether cannabis should be legalized are framed using criminological, economic, medical, and political themes. The political theme emerged most frequently in all reports. Findings indicate that there is an association between the tone of positive reporting and subsequent cannabis legalization in states where those reports originated. These findings have implications for allowing policymakers and healthcare professionals to build on their existing knowledge of the relationship between media, public opinion, and emerging cannabis policy. Finally, this study provides some context for the connection between a story’s theme, tone, and how they can shed light on cannabis legalization outcomes.
R&D and innovation after COVID-19: What can we expect? A review of prior research and data trends after the great financial crisis
Authors: Roper Stephen , Turner Joanne
Published: October 2020

How did the great financial crisis (GFC) of 2008–2010 impact on R&D and innovation in the United Kingdom and internationally? What can we learn about the likely innovation effects of the COVID-19 crisis on small and medium enterprises (SME) innovation? Numerous international studies suggest the strong procyclicality of R&D and innovation investments in firms: investment rises in recovery and falls sharply in times of crisis. This procyclicality is driven in firms by both internal financial resources or slack and varying market incentives for innovation. Cash constraints, in particular, may impact most strongly on R&D and innovation investments by smaller firms. In the United Kingdom, the proportion of innovating firms fell by around a third during the GFC and took around four to six years to recover. Recovery was also uneven – notably weaker in some sectors and regions. The COVID-19 crisis seems likely to leave many firms financially weaker, with the most significant impacts on the willingness or ability of SMEs to sustain R&D and innovation. Where firms are able to sustain these investments, however, the evidence from the GFC suggests that they will lead to better survival chances, stronger growth and higher profitability. Some additional financial support for innovation has been announced by the UK government. Whether this will be sufficient to sustain SME levels of innovative activity, however, remains to be seen.
Unsociability, Peer Rejection, and Loneliness in Chinese Early Adolescents: Testing a Cross-Lagged Model
Authors: Xiao Bowen , Bullock Amanda , Liu Junsheng , Coplan Robert
Published: October 2020

In this study, we explored the longitudinal linkages among Chinese early adolescents’ unsociability, peer rejection, and loneliness. Participants were N = 445 primary school students in Shanghai, P.R. China followed over 3 years from Grades 6 and 7 to Grades 8 and 9. Measures of adolescents’ unsociability, peer rejection, and loneliness were obtained each year from a combination of self-reports and peer nominations. Among the results, (1) compared with the unidirectional and bidirectional models, the cross-lagged model was deemed the best fit for the data; (2) adolescent unsociability contributed to later increases in loneliness via a pathway through peer rejection; and (3) loneliness directly contributed to later increases in unsociability. Results are discussed in terms of the implications of unsociability for Chinese adolescents’ experience of peer rejection and subsequent loneliness.

Predicting river channel pattern based on stream power, bed material and bank strength
Authors: Candel Jasper , Kleinhans Maarten , Makaske Bart , Wallinga Jakob
Published: October 2020

Rivers exhibit a wide variety of channel patterns, and predicting changes in channel pattern is important in order to foresee river responses to climate change and river restoration. Many discriminators have been developed to define approximate boundary conditions for different channel patterns, based on channel-pattern-controlling parameters such as discharge and valley gradient. However, presently available discriminators have two main shortcomings. First, they perform poorly for rivers with cohesive, relatively erosion-resistant banks. For this subset, discriminators tend to indicate an actively meandering channel pattern, whereas the river morphology and dynamics show that many of these rivers should be classified as laterally stable. Second, channel pattern discriminators are often used to predict channel patterns, which is only valid when parameters are used that are independent of actual channel pattern. This condition is often not met, as many discriminators use the channel slope or width–depth ratio of the channel as input. To resolve both shortcomings, we first propose an additional class of rivers with scroll bars and tortuous channel patterns, which have an inhibited mobility due to their self-formed cohesive deposits. Second, we compare frequently used empirical and mechanistic channel pattern discriminators, taking into account the success in predicting channel pattern and the independence of causal factors used. Thirdly, we present a novel channel pattern discriminator and predictor that includes the effect of a cohesive floodplain, using the average silt-plus-clay fraction of the river banks as proxy. We show that this new predictor outperforms previously used empirical and mechanistic approaches, and successfully predicts channel pattern for 87% of the rivers from a dataset of 70. This new predictor is widely applicable, as it is relatively simple and based on easily obtainable, and mostly independent, parameters.

Development of a Simplified Model of Speed-Specific Vehicle-Specific Power Distribution Based on Vehicle Weight for Fuel Consumption Estimates
Authors: Zhang Zeyu , Song Guohua , Chen Jiaoyang , Zhai Zhiqiang , Yu Lei
Published: October 2020

The vehicle-specific power (VSP) distribution, as one of the fundamental inputs of VSP-based emission models such as the motor vehicle emission simulator model, is sensitive to vehicle weight. Developing field VSP distributions requires extensive vehicle type-specific trajectory data, which is expensive and time-consuming. On the other hand, estimating fuel consumption accurately by employing VSP distributions for various vehicle types is computationally highly complex. This study aims to develop a simplified model of speed-specific VSP distribution based on vehicle weight for fuel consumption. First, field speed-specific VSP distributions of eight types of vehicles are developed. Second, the Gaussian function is employed to fit the field speed-specific VSP distributions to “change” the discrete VSP distributions into continuous distributions to facilitate quantifying the relationship between VSP distributions and vehicle weights. Third, the relationship between VSP distributions and vehicle weights is quantified by employing polynomial functions. The results indicate the acceptable accuracy of the simplified model, with 93.8% of R2 of the Gaussian function being greater than 0.90. The error in estimating fuel consumption using the simplified model is acceptable. For vehicles weighing 1.5 t (1.5 metric tons), the average error is 6.3%. Besides the “hole filling” of VSP distributions of inaccessible vehicles, the simplified model will reduce the computational complexity of estimating fuel consumption by about 50%, which is beneficial for the realization of real-time online estimates of fuel consumption.
Simulation of Runway Operations with Application of Dynamic Wake Separations to Study Runway Limitations
Authors: Roa Julio , Trani Antonio , Hu Junqi , Mirmohammadsadeghi Navid
Published: October 2020

This paper presents an evaluation of runway operations at Chicago O’Hare International Airport to estimate the impact of proposed wake vortex separation including Recategorization Phase II and III dynamic separations. The evaluation uses a Monte Carlo simulation model that considers arrival and departure operations. The simulation accounts for static and dynamic wake vortex separations, aircraft fleet mix, runway occupancy times, aircraft approach speeds, aircraft wake circulation capacity, environmental conditions, and operational error buffers. Airport data considered for this analysis are based on Airport Surface Detection Equipment Model X records from Chicago O’Hare International Airport from January to November 2016. Dynamic wake separations are tailored to each unique set of conditions by using environmental and aircraft performance parameters as input and allowing aircraft to be exposed to the same wake vortex strength as in Recategorization Phase II (RECAT II). The analysis shows that further reductions beyond RECAT II for aircraft pairs separated by 2 nautical miles or less is not operationally feasible. These wake separations already result in little to no wake dependency. When this is the case, the challenges in wake separation are to meet runway occupancy times and to make sure aircraft separations allow for human operational variations without resulting in aircraft turnarounds or double-aircraft-occupancy runway violations.
Evaluating the effect of variable fiber content on mechanical properties of additively manufactured continuous carbon fiber composites
Authors: Hetrick Dakota R , Sanei Seyed Hamid Reza , Bakis Charles E , Ashour Omar
Published: October 2020

Fiber volume fraction is a driving factor in mechanical properties of composites. Micromechanical models are typically used to predict the effective properties of composites with different fiber volume fractions. Since the microstructure of 3D-printed composites is intrinsically different than conventional composites, such predictions need to be evaluated for 3D-printed composites. This investigation evaluates the ability of the Voigt, Reuss, and Halpin–Tsai models to capture the dependence of modulus and strength of 3D-printed composites on varying fiber volume fraction. Tensile coupons were printed with continuous carbon fiber-reinforced Onyx matrix using a Markforged Mark Two printer. Specimens were printed at five different volume fractions with unidirectional fibers oriented at either [Formula: see text] to obtain longitudinal, shear, and transverse properties, respectively. It is shown that the Voigt model provides an excellent fit for the longitudinal tensile strength and a reasonable fit for the longitudinal modulus with varied fiber content. For the transverse direction, while the Reuss model fails to capture the transverse modulus trend, the Halpin–Tsai model provides a reasonable fit as it incorporates more experimental parameters. Like conventional composites, addition of fibers degrades the transverse strength, and the transverse strength decreases with increasing fiber volume fraction. The shear modulus variation with fiber content could not be fitted reasonably with either Halpin–Tsai model or Reuss model.
Brief Anti-Ageism Messaging Effects on Physical Activity Motivation Among Older Adults
Authors: Menkin Josephine A. , Smith Jennifer L. , Bihary Joseph G.
Published: October 2020

When people have more negative perceptions about aging or attribute health decline to old age, they engage in less health promotion behavior. We tested whether an intervention of brief anti-ageism messages addressing views of aging could motivate engagement in physical activities at senior centers. Attendees aged 50 and older ( n = 349; Mage = 72, SD = 9) at seven centers were randomly assigned to read one of three intervention messages (different approaches addressing views of aging) or to not read a message before rating their likelihood of attending a variety of center programs, including physical activities. Multilevel regression models indicated the intervention increased motivation to attend physical activities compared with the control group among participants aged 72 and older. The three anti-ageism messages were similarly effective suggesting some flexibility in framing. The results indicate anti-ageism messages may be a scalable, low-cost approach to promoting physical activity in older adults.
Year 15 and the Preservation of Low-Income Housing Tax Credit Projects: Lessons from Detroit, Michigan
Authors: Deng Lan
Published: October 2020

This study examines the efforts to preserve the Low-Income Housing Tax Credits (LIHTC) projects that are at risk from their year-15 transition in Detroit, Michigan. Using the preservation framework recommended by the National Housing Trust, the paper first identifies the risks LIHTC projects in Detroit face. It then reports what major institutional actors in LIHTC developments have done in addressing those risks, with particular attention to the roles these actors have played in shaping preservation needs and actions. The study concludes by discussing what broader lessons can be learned from Detroit with regard to the preservation of LIHTC projects nationwide.
In the hands of one nineteenth-century whaling cooper: Finding ourselves at sea
Authors: Bosworth Amanda L.
Published: October 2020

The cooper, or barrel maker, on an American nineteenth-century commercial whaling voyage occupied such a valuable position that his life was not risked hunting whales. The cooper was both part of the action and distanced from it, enabling him to create, through his collection of casks of whale oil, the archive of the whaling voyage. A close reading of one cooper’s logbook from the 1850s allows us to consider the process of whaling from his standpoint, as well as to theorize how the cooper was like the archivist, the chronicler, of the voyage. The cooper gave the ocean a history by creating its archive with his barrels, bearing them safely to shore, and sharing them with the world. The single cooper discussed here presents readers with two archives – his barrels of whale oil and his private logbook – which expose two different temporalities in which the potential archives of scholars exist.
Defending the flag of a torpid empire: The VOC in Bengal, 1759-1763
Authors: Rommelse Gijs
Published: October 2020

In 1759, the VOC perpetrated a spectacular blunder. The Company’s management in Batavia took the decision to send an expedition to Bengal in order to hinder the EIC. The result was disastrous: the expeditionary force was defeated and the VOC could henceforth only continue its operations in Bengal at the sufferance of the British. Most historians have interpreted the expedition as ill-conceived. The ideological dimension seems to have gone completely unnoticed, however. This article contends that this should not only be regarded as a strategic error, but also as the consequence of ideological considerations. This case, it is argued, demonstrates the existence of a corporate self-perception – shared, or at least adhered to, by the highest managerial echelons – of the Company as a manifestation of the Dutch nation and the extension of its state. This patriotism was interwoven with overarching discourses on the identity of the slowly dissolving Republic.
Thermal and mechanical properties of biodegradable isotactic polypropylene
Authors: Mubarak Yousef Ahmad
Published: October 2020

In this study, the effects of two different biodegradable plastic additives on the thermal and mechanical properties of isotactic polypropylene were investigated, analyzed, and presented. Biosphere biodegradable plastic additive and another oxidative biodegradable plastic additive, D2W, were used in 0.25, 0.5, 1.0, 1.5, and 2.0 wt% to prepare two sets of isotactic polypropylene composites. Differential scanning calorimeter and optical polarized light microscope were used to analyze the obtained composites thermally while the mechanical properties of these composites were studied by conducting tensile and impact testing. The morphological results reveal that only monoclinic α spherulites were obtained when the polypropylene crystallizes isothermally from the melt, it was found that both biodegradable plastic additives used decreases the size of the spherulites and increases their densities per unit volume. The incorporation of the Biosphere within the polypropylene matrix raises the crystallization temperature while the existence of D2W within the matrix delays the crystallization process. The addition of 2 wt% of Biosphere allows polypropylene to crystallize at about 13°C higher than neat polypropylene. It has been found that the addition of the biosphere increases Young’s modulus, while decreases the yield strength, the elongation at break, and the impact strength. On the other hand, D2W as an oxidative biodegradable plastic additive increases the elongation at break and the impact strength while decreases the yield strength and Young’s modulus.
When Words Do Not Matter: Identifying Actions to Effect Diversity, Equity, and Inclusion in the Academy
Authors: Ballard Dawna , Allen Brenda , Ashcraft Karen , Ganesh Shiv , McLeod Poppy , Zoller Heather
Published: October 2020

It is time to move past the words—the well-crafted statements circulated by groups and organizations across the academy, the scholarly writing as displacement, the formal and informal critiques—as if they had some recognizable impact. Each of these rhetorical moves can be valuable in helping to effect larger cultural and structural shifts. Yet, alone, a variety of evidence suggests that these forms of communication fail at effecting diversity, equity, and inclusion (DEI). Therefore, through our varied areas of research and lived work experiences, we focus attention toward actions as sites of power and potential: (a) in faculty emotional labor and work (McLeod), (b) at various levels of university administration and structural change (Ashcraft and Allen), (c) in the time-based practices associated with the ways we teach and mentor graduate students (Ballard), and (d) in our corpus of scholarship (Ganesh and Zoller).
Evaluation of Inpatient Opioid Prescribing Resulting in Outpatient Opioid Prescriptions for Previously Opioid-Naive Internal Medicine Patients
Authors: Perkins Bryce , Huckleberry Yvonne , Bogdanich Ivana , Leelathanalerk Areerut , Huckleberry April , Konecnik Michaela , Miller David C. , Bailey Morgan , Bime Christian
Published: October 2020

Background:

Little data exist regarding inpatient opioid prescriptions as a potential contribution to the current opioid crisis. While pain management is essential to inpatient care, the ease of which opioids may be prescribed for all levels of pain may contribute to unnecessary inpatient exposure and new outpatient prescriptions. The aim of this study was to observe patterns of opioid prescribing potentially leading to new opioid prescriptions at hospital discharge for previously opioid-naive patients.

Methods:

This study was a single-center observational study of opioid-naïve internal medicine patients who were prescribed inpatient opioids. Patient charts were reviewed to assess the patterns of inpatient opioid and non-opioid analgesic use, new opioid prescriptions upon discharge and medical record documentation justifying the need for outpatient therapy.

Results:

Among the 101 patients included in this study, 71 were prescribed IV opioids and 45 were prescribed both IV and oral opioids. Non-opioid analgesics were available for 78 patients. Twenty patients were discharged with a new prescription. The mean duration of outpatient prescriptions was 3.85 +/- 1.85 days with mean morphine milligram equivalents (MME) of 44.25 +/- 22.16. Among patients receiving these outpatient prescriptions, 11 had reference to the therapy in the discharge summary.

Conclusions:

This observational study describes an opportunity to improve inpatient opioid prescribing practices which may reduce new prescriptions for continued outpatient therapy. Further work should focus on optimizing use of non-opioid analgesia, minimizing use of IV opioids and requiring prescribers to justify the indication for new opioid prescriptions upon hospital discharge.
Wisdom and fear of God in Ben Sira 1:11–21: Second temple perspectives
Authors: Corley Jeremy
Published: October 2020

While Ben Sira’s poem on wisdom and fear of God (Sir 1:11–21) draws on earlier texts from the Hebrew Bible, it transfers the rewards for wisdom (Prov 1–9) and the blessings for Torah obedience (Deut 30:15–16) onto the fear of the Lord. The poem also exhibits parallels to some Dead Sea Scroll texts, including the Qumran Wisdom Admonition (4Q185) and the Treatise on the Two Spirits from the Community Rule (1QS III, 13–IV, 26). Since Sir 1:14 teaches that wisdom has been given in the womb to the faithful Jews, the “eternal foundation” (1:15) may be a reference to the Jerusalem temple.
An improved Jacobian-Torsor model for statistical variation solution in aero-engine rotors assembly

Published: October 2020

Rotor assembly is one of the core components of aero-engine, which basically consists of multistage revolving components. With the influence of parts’ manufacturing errors and practical assembly technology, assembly variations are unavoidable which will cause insecurity and unreliable of the whole engine. Statistical variation solution is a feasible means to analyze assembly precision. When using the three-dimensional variation analysis in rotor assembly, two key issues cannot be well solved, which involve the variation expression (the over-positioning problem of multiple datums) and the variation propagation (revolving characteristic of the rotors). To overcome the deficiency, extended Jacobian matrix and updated torsor equation were derived and unified, which eventually resulted in the improved Jacobian-Torsor model. This model can both provide rotation regulating mechanism by introducing the revolution joint, and characterize the interaction between essential mating features. Multistage rotational optimization of four-stage aero-engine rotors assembly has been performed to demonstrate this solution in statistical way. Results showed that the proposed model was applicable and conducive to precision prediction and analysis in design preliminary stage.

This paper presents a methodology for precision manufacture of a nozzle using the hybrid laser powder-bed fusion (L-PBF) technology. A new distortion predictive model for hybrid L-PBF was developed using finite element techniques. The model was validated against experimentally measured distortion using optical scanning. The validated model was utilised to mitigate distortion by applying additional stiffeners to the nozzle geometry where the distortion was reduced by 60% to acceptable tolerance of ± 200 µm. Micro-milling trials were conducted to identify optimum cutting parameters delivering high material removal rates while maintaining the average surface roughness of less than 1 µm. Finally, a nozzle with reduced distortion and desirable surface finish was manufactured, which has been used in industrial research context for process and product development of food products.
A weighting method for simultaneous adjustment for confounding and joint exposure-outcome misclassifications
Authors: Penning de Vries Bas BL , van Smeden Maarten , Groenwold Rolf HH
Published: October 2020

Joint misclassification of exposure and outcome variables can lead to considerable bias in epidemiological studies of causal exposure-outcome effects. In this paper, we present a new maximum likelihood based estimator for marginal causal effects that simultaneously adjusts for confounding and several forms of joint misclassification of the exposure and outcome variables. The proposed method relies on validation data for the construction of weights that account for both sources of bias. The weighting estimator, which is an extension of the outcome misclassification weighting estimator proposed by Gravel and Platt (Weighted estimation for confounded binary outcomes subject to misclassification. Stat Med 2018; 37: 425–436), is applied to reinfarction data. Simulation studies were carried out to study its finite sample properties and compare it with methods that do not account for confounding or misclassification. The new estimator showed favourable large sample properties in the simulations. Further research is needed to study the sensitivity of the proposed method and that of alternatives to violations of their assumptions. The implementation of the estimator is facilitated by a new R function (ipwm) in an existing R package (mecor).
Cultural Dynamics for Sustainability: How Can Humanity Craft Cultures of Sustainability?
Authors: Kashima Yoshihisa
Published: October 2020

Humanity faces twin problems of adaptation—natural environmental challenges of climate change and global humanitarian challenges of ensuring well-being for all—that pose a dilemma for sustainable development. One way forward is to develop cultures of sustainability that highlight and reward the ideas and practices that will help us transition to a sustainable lifestyle. Although institutional responses are necessary and multidisciplinary approaches are required, individual citizens can also participate in cultural dynamics—the process of cultural formation, maintenance, and transformation—to craft cultures of sustainability, and psychological science can point to potential mechanisms for effecting this cultural change. Informed by the niche-construction perspective, I suggest that the critical ingredients of cultures of sustainability include (a) conceptions of human–nature connectedness, (b) conceptions of human–artifact relation, (c) interpersonal conversations about sustainability norms within social networks, and (d) visions of an achievable utopia for a sustainable future. Further research and action are called for.

Autonomy has been recognised as a key principle in healthcare, but we still need to develop a consistent understanding of older people’s perceived autonomy in residential care. This study aimed to identify, describe and synthesise previous studies on the perceived autonomy of older people in residential care. Ethical approval was not required, as this was a review of published literature. We carried out an integrative review to synthesise previous knowledge published in peer-review journals in English up to September 2019. Electronic and manual searches were conducted using the CINAHL, Philosopher’s Index, PubMed, SocINDEX, Scopus and Web of Science databases. The data were analysed using the constant comparison method. The review identified 46 studies. Perceived autonomy referred to the opportunities that older people had to make their own choices about their daily life in residential care, and achieving autonomy promoted both health and quality of life. Autonomy was linked to older people’s individual capacities, including their level of independence, physical and mental competence, personal characteristics, and whether relatives shared and supported their perceived autonomy. Professionals could facilitate or hinder older peoples’ autonomy in a number of ways, including providing opportunities for autonomy, how daily care needs and activities were managed, and controlling older people’s choices. Professionals’ characteristics, such as education and attitudes, and the older people’s living environments were also associated with their perceived autonomy and included organisational characteristics and physical and social care facilitators. Older people’s perceived autonomy promoted health and quality of life in residential care. However, their autonomy was associated with a number of protective and restrictive individual and environmental factors, which influenced whether autonomy was achieved.
