Hidden Fluids in Plain Sight: Identifying Intravenous Medication Classes as Contributors to Intensive Care Unit Fluid Intake
Authors: Gamble Kelly C. , Smith Susan E. , Bland Christopher M. , Sikora Newsome Andrea , Branan Trisha N. , Hawkins William Anthony
Published: May 2021

Introduction: Fluid stewardship targets optimal fluid management to improve patient outcomes. Intravenous (IV) medications, flushes, and blood products, collectively referred to as hidden fluids, contribute to fluid intake in the intensive care unit (ICU). The impact of specific IV medications on fluid intake is unknown. Objective: Characterize IV medication classes based on contribution to ICU fluid intake by frequency of administration and total volume infused to identify targets for fluid stewardship. Methods: This multi-center, retrospective nested cohort study included patients admitted to a medical or surgical ICU between January 2017 and December 2018. The primary outcome was to identify the volume contribution of specific IV medication classes administered over the first 3 ICU days. Secondary outcomes were the administration frequency of these medications and their proportion of total daily volume intake over the first 3 ICU days. Results: The study included 210 patients. The largest mean administration volumes over the course of the first 3 ICU days were attributed to antibacterials (968 ± 846 mL), vitamins/minerals/electrolytes (416 ± 935 mL), pain/agitation/delirium agents (310 ± 512 mL), and vasoactive agents (282 ± 744 mL). The highest frequencies over the course of the first 3 ICU days were attributed to antibacterials (n = 180; 86%), pain/agitation/delirium agents (n = 143; 68%), vitamins/minerals/electrolytes (n = 123; 59%), and vasoactive agents (n = 96; 46%). IV medications contributed 2601 ± 2573 mL of fluid volume per patient over the first 3 ICU days, accounting for 42% ± 29% of overall volume. Conclusion: IV medications contribute over 40% of total fluid intake within the first 3 days of ICU admission, with antibacterials as top contributors by administration volume and frequency. Future research implementing fluid stewardship to ICU fluid sources, such as concentrating IV medications, switching IV medications to oral formulations, de-escalation of antibacterials, and reduction of maintenance fluids, should be performed to minimize hidden fluids from IV medications.
The NFHS-5 Sanitation Story: Case for Moving from Access to Adoption
Authors: Seth Payal
Published: May 2021

This commentary analyses the recently launched National Family Health Survey (NFHS-5) (2019–2020) factsheet to investigate the claim of an open defecation free (ODF) India. The official data from Swachh Bharath Mission (SBM) was used to declare India ODF on 2 October 2019. The SBM statistics reported that India has achieved 100% sanitation coverage, that is, the fraction of households with access to individual household latrines (IHHLs). However, the NFHS-5 data shows that even though India witnessed an improvement in sanitation in the past four to five years, we are far from achieving universal elimination of open defecation. In an attempt to evaluate the differing claims made regarding India’s ODF status by two Government of India’s data sources, I explain the distinction in their objectives. While the SBM captures access to IHHLs, NFHS-5 records the place which the members of the household usually use for defecation. The two datasets jointly suggest that access to toilets does not concurrently translate to its usage. Hence, determining the ODF status of Indian communities on mere access to toilets is an inadequate representation of the sanitation environment. There is substantial merit in moving the sanitation outcomes from access to the adoption of toilets.
Central Vigilance Commission: A Perspective Based on Historical Indian World View and Statecraft
Authors: Pande Sanjay , Jain Neetu
Published: May 2021

Central Vigilance Commission is the apex integrity institution of the nation. It was formed by the government on the recommendations of the Santhanam Committee by way of a Resolution on 11 February 1964. Over the period, unparalleled services have been rendered by the Commission to the nation in the field of anti-corruption. However, a far more important role played by the Commission is that it has grown from strength to strength, while many other institutions of national importance kept falling apart during this time. Its functioning has instilled a great degree of trust amongst the common public, and needless to say that this trust is the life blood of a democracy. The Commission is however, faced with an uphill task of fighting corruption raising its head in view of a fast-developing economy in a society which is becoming complex day by day. The Commission is an institution which will be looked up to in the decade to come. Its functioning will be closely scrutinised and criticised. Though much has been written and recorded on the Commission, a perspective about the Commission from the angle of historical Indian world view and statecraft is not available. This is a curious gap in the body of knowledge as the Commission’s formation draws a lot from ancient Indian world view and statecraft. The article attempts to bridge this profound gap in the literature relating to the Central Vigilance Commission.
New identification method for computer numerical control geometric errors
Authors: Yang Hongtao , Shen Mei , Li Li , Zhang Yu , Ma Qun , Zhang Mengyao
Published: May 2021

To address the problems of the low accuracy of geometric error identification and incomplete identification results of the linear axis detection of computer numerical control (CNC) machine tools, a new 21-item geometric error identification method based on double ball-bar measurement was proposed. The model between the double ball-bar reading and the geometric error term in each plane was obtained according to the three-plane arc trajectory measurement. The mathematical model of geometric error components of CNC machine tools is established, and the error fitting coefficients are solved through the beetle antennae search particle swarm optimization (BAS–PSO) algorithm, in which 21 geometric errors, including roll angle errors, were identified. Experiments were performed to compare the optimization effect of the BAS–PSO and PSO and BAS and genetic particle swarm optimization (GA–PSO) algorithms. Experimental results show that the PSO algorithm is trapped in the local optimum, and the BAS–PSO is superior to the other three algorithms in terms of convergence speed and stability, has higher identification accuracy, has better optimization performance, and is suitable for identifying the geometric error coefficient of CNC machine tools. The accuracy and validity of the identification results are verified by the comparison with the results of the individual geometric errors detected through laser interferometer experiments. The identification accuracy of the double ball-bar is below 2.7 µm. The proposed identification method is inexpensive, has a short processing time, is easy to operate, and possesses a reference value for the identification and compensation of the linear axes of machine tools.
Simulation of response spectrum-compatible ground motions using wavelet-based multi-resolution analysis
Authors: Chen Guan , Zhu Zhiren , Hu Jun
Published: May 2021

This study proposed a simple and effective response spectrum-compatible ground motions simulation method to mitigate the scarcity of ground motions on seismic hazard analysis base on wavelet-based multi-resolution analysis. The feasibility of the proposed method is illustrated with two recorded ground motions in El Mayor-Cucapah earthquake. The results show that the proposed method enriches the ground motions exponentially. The simulated ground motions agree well with the attenuation characteristics of seismic ground motion without modulating process. Moreover, the pseudo-acceleration response spectrum error between the recorded ground motion and the average of the simulated ground motions is 5.2%, which fulfills the requirement prescribed in Eurocode 8 for artificially simulated ground motions. Besides, the cumulative power spectra between the simulated and recorded ground motions agree well on both high- and low-frequency regions. Therefore, the proposed method offers a feasible alternative in enriching response spectrum-compatible ground motions, especially on the regions with insufficient ground motions.
Sanctions and Third-party Compliance with US Foreign Policy Preferences: An Analysis of Dual-use Trade
Authors: Peterson Timothy M.
Published: May 2021

Ostensibly bilateral US foreign policy actions, such as sanctions, can influence third-party compliance with US policy preferences. US sanctions simultaneously signal US preferences and demonstrate leverage, which can motivate third parties to avoid or change proscribed behavior proactively. Empirical testing of this strategic behavior typically is difficult given that it predicts non-events in a noisy signaling environment. However, I argue that the global trade of dual-use commodities—those with both civilian and military purposes—is a phenomenon where we can observe this process systematically. I isolate US sanctions that provide relevant context both by stigmatizing the target and signaling that third-party dual-use exports to the target would directly undermine US policy goals. Using newly-coded bilateral data spanning the post-Cold War period, I find evidence that relevant US sanctions are associated with lower third-party dual-use exports to US-sanctioned states. My findings have implications for scholars and policy-makers, suggesting a broad yet shrouded ability of sanctions to advance US foreign policy goals.
Mechanisms of Enamel Mineralization Guided by Amelogenin Nanoribbons
Authors: Habelitz S. , Bai Y.
Published: May 2021

The nanofibrous nature and its intricate structural organization are the basis for the extraordinary ability of sound enamel to outlive masticatory forces at minimal failure rates. Apatite nanofibers of several hundreds of micrometers to possibly millimeters in length originate during the secretory stage of amelogenesis as 2-nm-thin and 15-nm-wide ribbons that develop and grow in length under the guidance of a dynamic mixture of specialized proteins, the developing enamel matrix (DEM). A critical role in the unidirectional and oriented growth of enamel mineral ribbons has been attributed to amelogenin, the major constituent of the DEM. This review elaborates on recent studies on the ability of ribbon-like assemblies of amelogenin to template the formation of an amorphous calcium phosphate precursor that transforms into apatite mineral ribbons similar to the ones observed in developing enamel. A mechanistic model of the biological processes that drive biomineralization in enamel is presented in the context of a comparative analysis of enamel mouse models and earlier structural data of the DEM emphasizing a regulatory role of the matrix metalloproteinase 20 in mineral deposition and the involvement of a process-directing agent for the templated mineral growth directed by amelogenin nanoribbons.
Alveolar Bone Marrow Gli1+ Stem Cells Support Implant Osseointegration
Authors: Yi Y. , Stenberg W. , Luo W. , Feng J.Q. , Zhao H.
Published: May 2021

Osseointegration is the key issue for implant success. The in vivo properties of cell populations driving the osseointegration process have remained largely unknown. In the current study, using tissue clearing–based 3-dimensional imaging and transgenic mouse model-based lineage tracing methods, we identified Gli1+ cells within alveolar bone marrow and their progeny as the cell population participating in extraction socket healing and implant osseointegration. These Gli1+ cells are surrounding blood vessels and do not express lineage differentiation markers. After tooth extraction and delayed placement of a dental implant, Gli1+ cells were activated into proliferation, and their descendants contributed significantly to new bone formation. Ablation of Gli1+ cells severely compromised the healing and osseointegration processes. Blockage of canonical Wnt signaling resulted in impaired recruitment of Gli1+ cells and compromised bone healing surrounding implants. Collectively, these findings demonstrate that Gli1+ cells surrounding alveolar bone marrow vasculature are stem cells supporting dental implant osseointegration. Canonical Wnt signal plays critical roles in regulating Gli1+ stem cells.

Carbodiimide (EDC)–based dentin primers preserve hybrid layer (HL) integrity. However, aging >1 y has not been investigated. The present study examined whether the cross-linking effect of EDC was reflected in dentin bond strength, endogenous enzymatic activity, and the chemical profile of the HL after 5-y aging in artificial saliva. Noncarious human third molars ( N = 42) were cut to expose middle/deep coronal dentin and treated as follows: group 1, dentin etched with 35% H3PO4, pretreated with a 0.3M aqueous EDC primer for 1 min and restored with XP Bond (Dentsply Sirona); group 2, as in group 1 but without EDC pretreatment; group 3, Clearfil SE Bond (Kuraray-Noritake) primer applied to dentin surface, followed by EDC pretreatment as in group 1 and application of bond; group 4, as in group 3 without EDC pretreatment. After composite buildup, the specimens were cut into sticks or slabs, depending on the experiment. All tests were performed at baseline (T0) and after 5 y of aging (T5) in artificial saliva at 37 °C. Microtensile bond strength (µTBS) was tested at a crosshead speed of 1 mm/min until failure. Endogenous enzymatic activity was investigated with in situ zymography. The chemical profile of HL was determined via Raman spectroscopy. Three-way analysis of variance and post hoc Tukey test were used to analyze µTBS and in situ zymography data (α = 0.05). EDC pretreatment and aging significantly influenced µTBS and in situ zymography results ( P < 0.05). Higher bond strength and lower gelatinolytic activity were identified in the EDC-treated groups at T5 ( P < 0.05), especially in the etch-and-rinse groups. Raman spectra revealed less defined amide III peaks in control specimens at T5. The EDC cross-linking effect persisted in the HL for 5 y in terms of bond strength, collagen structure preservation, and dentinal enzyme silencing.
Traditional Indian Education Values and New National Education Policy Adopted by India
Authors: Patil Varsha Kiran , Patil Kiran D.
Published: May 2021

Ancient Indian education was value-based consisting of Gurukul system and world-famous “Nalanda and Takshashila Universities.” The value-based education policy reforms were the basis for utilizing the knowledge for benefits of mankind. In ancient Bharat, there were knowledgeable personalities like Sushrut, Aryabhatta, Panini, and Chanakya who set examples in front of the world. The national long-term impact is its shift from 10+2 pattern to 5+3+3+3+4. This decision will bring a major change in Indian education system after three decades. The new National Education Policy is promoting Indian value-based education with all-inclusive ecodevelopment of Holistic Education, Bharat-centric Education, Development of Knowledge-based Society, and Emphasis on Knowledge-based Education.
MAXAMBA and Memory-Making Amid Traumatic Displacement
Authors: Barnard Suzanne , Greene Eric , Gupta Nisha
Published: May 2021

In this edited interview, psychologists Eric Greene and Nisha Gupta converse with filmmaker and psychologist Suzanne Barnard about her film MAXAMBA. MAXAMBA was created as a sensory ethnographic memory of inhabitants of Lisbon’s Quinta da Vitória neighborhood as they awaited the neighborhood’s final demolition. The film focuses on the daily life of an Indian Portuguese couple who emigrated from Mozambique (a former colony of Portugal) to Lisbon in the 1970s. The husband and wife both work out of their home in the neighborhood. As tailors, they have a close relationship with the other inhabitants, and they are especially integrated into the Hindu community that lives in this neighborhood. In this dialogue, Suzanne describes the film as constructing a virtual or living memory out of coexisting planes of past, present, and future—a memorial process that seeks to honor the everyday life of the couple prior to their traumatic displacement. She also explores how the film attempts to mobilize an intervention in the neighborhood’s representation in the city, and reflects on opportunities and limitations for art activism through the vehicle of filmmaking.
The effectiveness of mediation and peacekeeping for ending conflict
Authors: Clayton Govinda , Dorussen Han
Published: May 2021

Mediation and peacekeeping are commonly used tools to manage conflict. To what extent are they complementary and effective instruments for ending violent conflicts? Generally, they are seen as distinct tools: mediation aims to facilitate negotiated settlements, while the goal of peacekeeping is to prevent agreements from collapsing. However, peacekeeping and mediation regularly occur simultaneously. Arguably, peacekeeping operations rely on continuing political processes, while peacekeepers create a context favorable for mediation and provide a valuable source of independent information. Using a variety of model specifications, including selection models, empirical evidence supports that (a) mediation rather than peacekeeping is key to halting hostilities, (b) mediation and peacekeeping are largely complementary, but (c) this complementarity is conditional: in the post-Cold War period, transformative peacekeeping boosted the effectiveness of mediation to halt civil wars. There is no evidence that peacekeeping on its own matters for ending conflict. Finally, counterfactual analysis shows the substantial impact of mediation and peacekeeping on the frequency of conflict.
Understanding what works in the police management of child sex offenders in the community
Authors: Christensen LS , Rayment-McHugh S , McKillop N , Cairns N , Webster J
Published: May 2021

Police are becoming increasingly responsible for monitoring convicted child sex offenders in the community. A Rapid Evidence Assessment was undertaken to capture ‘what works’ and what ‘shows promise’ in existing and emerging, innovative policing practices. A total of 920 searches were performed across five databases, spanning the last 5 years. After removal of duplicates and those that did not meet inclusion criteria, 61 articles were analysed. Two key strategies, with sub-strategies, emerged: (1) formalised, targeted management and (2) technology-assisted management. An adapted ‘EMMIE’ framework presents the ‘effects’, the overarching ‘mechanisms’ and ‘moderators’ of success, and ‘implementation’ considerations for effective practice.
Surfacing Deep Challenges for Social-Educational Justice: Putting Funds, Wealth, and Capital Frameworks into Dialogue
Authors: Colina Neri Rebecca , Zipin Lew , Rios-Aguilar Cecilia , Huerta Adrian H.
Published: May 2021

This paper critically explores theoretical, conceptual, and methodological dimensions of three social-justice oriented educational approaches: Bourdieuian Analysis of Capital (BAC), Funds of Knowledge (FK), and Community Cultural Wealth (CCW). We surface convergences and divergences across these three frameworks, seeking to clarify them conceptually, draw out implications for educational praxis, illuminate importantly difficult tensions in-and-across them, and (re)imagine future directions for utilizing these frameworks to address intersecting structural inequalities in the pursuit of strengthened social-educational justice. We argue that putting BAC, FK, and CCW into mutual interrogation can deepen understanding of these inequalities and ways to approach them in education praxis.
Funds of Knowledge, Community Cultural Wealth, and the Forms of Capital: Strengths, Tensions, and Practical Considerations
Authors: Rios-Aguilar Cecilia , Neri Rebecca Colina
Published: May 2021

Funds of Knowledge (FK), Community Cultural Wealth (CCW), and Bourdieu’s analysis of capital (BAC) have each been applied in powerful ways to address complex issues of urban education; however, the overlaps and tensions between them have been largely underexplored. When brought together, these three economic metaphors—funds, wealth, capital—surface divergences and tensions that foreground questions of educational praxis and social justice. We argue the quest for social justice requires an approach that both validates and substantively utilizes learners’ FK and CCW and critically grapples with the pervasive logic of capital that has been impressed in the fabric of our educational system.
Surprising Causes: Propensity-adjusted Treatment Scores for Multimethod Case Selection
Authors: Galvin Daniel J. , Seawright Jason N.
Published: May 2021

Scholarship on multimethod case selection in the social sciences has developed rapidly in recent years, but many possibilities remain unexplored. This essay introduces an attractive and advantageous new alternative, involving the selection of extreme cases on the treatment variable, net of the statistical influence of the set of known control variables. Cases that are extreme in this way are those in which the value of the main causal variable is as surprising as possible, and thus, this approach can be referred to as seeking “surprising causes.” There are practical advantages to selecting on surprising causes, and there are also advantages in terms of statistical efficiency in facilitating case-study discovery. We first argue for these advantages in general terms and then demonstrate them in an application regarding the dynamics of U.S. labor legislation.
From Stepping-Stones to Throwing Stones: Officers’ Liability for Corporate Compliance Failures after Cassimatis
Authors: Hanrahan Pamela , Bednall Tim
Published: May 2021

Australian corporate law allows for significant civil penalties to be imposed by a court on negligent corporate officers, including directors. For more than a decade, Australian Securities and Investments Commission used civil prosecutions for negligence exclusively in situations where an officer is alleged to have exposed their corporation to foreseeable risk of harm that would flow from a contravention by the corporation of a regulatory or disclosure obligation. This enforcement strategy—known as ‘stepping-stones’—has been strongly criticised, including by Rares J in his 2020 dissenting opinion in the Cassimatis appeal. This article explains how stepping-stones works as an enforcement strategy in the context of corporate compliance failures, explores the various criticisms of it, and argues for reform. It proposes a legislative alternative that rebalances individual officer liability, to reflect contemporary governance practices and encourage better management and oversight of non-financial risk in corporations.
Firesetting Reoffending: A Meta-Analysis
Authors: Sambrooks Katie , Olver Mark E. , Page Thomas E. , Gannon Theresa A.
Published: May 2021

Despite the significant adverse consequences of deliberate firesetting, it has been unclear what proportion of individuals repeat this problematic behavior, owing to methodological differences and large variability in reported reoffending rates. A meta-analysis of 25 samples of untreated adults and children with a history of firesetting, examining reoffending over a follow-up period, was conducted. The base rates of reoffending from this meta-analysis indicated that between 57% and 66% of untreated firesetters engage in general reoffending, between 8% and 10% engage in criminal arson, and around 20% engage in deliberate firesetting behavior. The odds of firesetting during the follow-up period were 5 times greater for known firesetters in comparison with other offenders. Clinical and criminological correlates of reoffending, including age, are examined. Implications for enabling evidence-based practice with this population, including defensible risk assessments and treatment provision, are discussed.
Proverbs of administration at 75: Long live proverbs?
Authors: Auer Matthew R
Published: May 2021

On the 75th anniversary of Herbert A Simon’s “Proverbs of Administration,” it is fitting to consider its place in the public administration canon, with an eye to contemporary realities. In Proverbs, Simon interrogated prevailing mid-century “principles of public administration.” But even as he reduced in rank each “principle,” he preserved a central tenet of earlier pioneers of a “science of administration”—namely that public administration theory should focus, first and foremost, on administrative efficiency. Seven and a half decades after its publication, a clear-eyed examination of Simon’s essay is in order, with attention to both its historical and contemporary contexts. This essay urges that the administrative efficiency tenet was already on unstable ground at the time of Proverbs’ publication, rendering Simon’s reformist agenda less than paradigm-changing. In the contemporary context, the democratic shortcomings of Simon’s agenda are even more apparent. Proverbs is out of synch with the goals for public administration promulgated by respected associations in the field. Simon’s approach also lacks inspiration for students of public service eager to shore up the American democratic project amidst unprecedented challenges.
Institutional and programmatic determinants for graduate public affairs’ online education: Assessing the influence of faculty workload

Published: May 2021

The research explores why some public affairs graduate programs choose to develop fully online degree offerings while others do not. The study attempts to address questions surrounding how different institutions and programs are pursuing degree offerings and the potential influence of faculty workload. The research utilizes a quantitative, cross-sectional design analyzing results from a survey on institutional and programmatic practices in workload, hiring, and degree offerings administered to primary points of contact within public affairs academic units from all institutions found in the US News World Report Graduate Programs in Public Affairs Rankings from 2019. Survey data is paired with program information from the accrediting body institutional member database. Findings indicate differences from both institutional and programmatic groupings do demonstrate workload measures have unique characteristics depending upon the type of institution and rank of the program. Further analysis discusses the influence of the COVID-19 pandemic on future public affairs programming.

Welcome to Be Like Us: Expectations of Outgroup Assimilation Shape Dominant Group Resistance to Diversity
Authors: Danbold Felix , Huo Yuen J.
Published: May 2021

We propose a theoretical framework for when and why members of dominant groups experience threat and express intolerant attitudes in response to social change. Scholarship on symbolic threat suggests that the detection of intergroup differences in values and norms is sufficient to elicit negative intergroup attitudes. Building on this theory, we argue that the experience of threat is actually shaped by prospective beliefs about difference (i.e., expectations of whether outgroups will assimilate to ingroup norms over time or not). Across two studies and two accompanying pilots, we show how outgroup assimilation expectation shapes dominant groups’ experiences of threat, specifically as it relates to their ability to define the norms of their superordinate category (prototypicality threat). We observe that members of dominant groups are surprisingly tolerant of both social change and intergroup difference in the present, so long as they expect outgroup assimilation in the future.
Parents of Preterm and Very Low Birthweight Infants and Their Childrearing Practices
Authors: Koldoff Elizabeth A. , Holtzclaw Barbara J. , Kolobe Thubi H. A.
Published: May 2021

Emerging research supports that early intervention leads to better health and higher functional status for infants with very low birthweight and/or low gestational age. Optimizing the transition from neonatal intensive care to early intervention programs relies heavily on parent engagement. The purpose of this descriptive correlational study was to investigate the relationship between parental characteristics, childrearing behaviors, and participation in early intervention. We used convenience sampling of 49 parents who participated in early intervention and the Parent Behavior Checklist to assess parent characteristics. Correlation coefficients between parenting behaviors, birthweight, and participation in early intervention were low. An important finding was that most parents in this study were within the “average” range for childrearing practices, despite the documented challenges associated with very low birthweight or gestational age. Despite documented challenges, parents of preterm infants with very low birthweight and parents of typical birthweight infants have similar parenting beliefs and behavior.
Remittances and Protests against Crime in Mexico
Authors: Ley Sandra , Olivo J. Eduardo Ibarra , Meseguer Covadonga
Published: May 2021

The resource mobilization theory has long emphasized the role of resources in facilitating collective mobilization. In turn, recent research on crime and insecurity in Mexico has drawn attention to the role of local networks of solidarity in facilitating mobilization against crime. We rely on these two literatures to propose that remittances — that is, the resources that emigrants send to their relatives left behind — deserve attention as international determinants of this type of non-violent anti-crime mobilization. Further, relying on recent research on remittances’ impact on political behavior, we hypothesize that the relationship between remittances and contentious action is non-linear, exhibiting a positive effect at low to moderate levels of inflows and declining at higher levels of remittances. We contend that at low to moderate levels, international remittances provide the necessary resources for collective activation. At greater levels of remittance inflows, however, lessened economic and security grievances imply a decline in the probability of protesting. Overall, we show that emigrant remittances matter for organizing protests against criminality at the subnational level but that they produce both an engagement and disengagement effect, depending on the size of the inflows.
Acute urinary retention in a 27-year-old male secondary to benign prostatic hyperplasia treated with Holmium Enucleation of the Prostate (HOLEP)
Authors: Napier-Hemy Timothy P , Liu Alan King Lun , Floyd Michael S , McNulty Sid , Omar Ahmad M , Mistry Rahul , Gana Hosea BY
Published: May 2021

Introduction:

Benign prostatic hyperplasia (BPH) is common in the ageing male. Clinical manifestations like retention impact on a patient’s quality of life. Alterations in androgen activity at the androgen receptor complex level in the prostate contribute to prostatic hyperplasia with the highest incidence occurring in males in their 70’s. There remains a paucity of cases in young males who develop acute urinary retention secondary to BPH. We present a case of a 27-year-old male who developed acute urinary retention secondary to BPH who required a Holmium Laser Enucleation of his Prostate (HOLEP).

Case description:

A 27 year old man was admitted in acute urinary retention. BPH was diagnosed via way of radiological imaging and histological assessment. After pre-operative sperm banking and suprapubic catheterisation, the patient underwent a HOLEP. He had biochemically confirmed hypogonadotrophic hypogonadism which was at odds with his muscular, physical appearance. Total testosterone levels had fluctuated following admission suggesting an exogenous substance was interfering with the hypothalamic-pituitary-gonadal axis but he denied exogenous steroid use.

Result:

The patient successfully passed his voiding trial on the second post-operative day and remained catheter free. Post-operative uroflowmetry and sexual function remain unknown as patient disengaged with follow up.

Conclusion:

HOLEP prostatectomy is a safe and effective way of managing BPH in younger patients following sperm banking and assessment by endocrinology.
Conspicuously Concealed: Federal Funding, Knowledge Production, and the Criminalization of Gun Research
Authors: Carlson Jennifer , James Rina
Published: May 2021

A popular narrative in the U.S. gun debate concerns federal funding of gun research: Because of a right-wing backlash against gun-related public health research (centered on the controversial Kellermann et al. study), federal funding of gun research has been frozen since the mid-1990s. How accurate is this popular “funding freeze” narrative—or is the federal funding of gun research better described as a “chill”? If the latter, what kinds of funding have persisted within this “chill”? Drawing on public data on funded project abstracts from 1996 to 2016 from three major federal institutes (the National Institute of Justice, the National Science Foundation, and the National Institutes of Health), this paper shows that despite funding cuts to the Centers for Disease Control and Prevention (CDC), federal funding for gun research has continued, especially for studies that construct the focus of their study as gun crime. Specifically, we find that a criminal justice approach to the study of guns and gun-related topics dominates the project abstracts analyzed and that this approach also casts a shadow on other approaches—especially public health and social justice approaches—to the research of guns. Examining federally funded gun research from a social constructionist lens provides insight not just into federal funding of gun research but also into the dominant framings of gun policy within the United States: criminal justice approaches to gun research may reinforce an understanding of gun violence as a problem of crime and justify criminalizing strategies in gun policy.
The Relationship Between Children’s Gender Composition and Parents’ All-Cause Mortality Among Older Adults in Korea
Authors: Kim Jinho
Published: May 2021

Using data from the Korean Longitudinal Study of Aging ( N = 3,356 participants aged 65 or older) and estimating Cox proportional hazard regression models, this study investigated the association between gender composition of children and parents’ mortality risk. This study showed that compared with having both daughters and sons, having exclusively daughters (but not exclusively sons) was associated with higher mortality risk. This association, however, was significant for mothers, but not for fathers. To shed light on source of this association, this study distinguished between mothers with only daughters who receive and do not receive regular financial support from children. Results showed that mothers had elevated mortality risk only if they do not receive regular financial support from their children. Traditional caregiving roles of sons for older parents in Korea may lead to a mortality disadvantage among mothers of daughters vis-à-vis a reduction in financial assistance from children.
Medicare Usage Changes in Nursing Homes and Their Impacts on Long-Stay Resident Outcomes
Authors: Lepore Michael , Barch Daniel H.
Published: May 2021

Medicare provides skilled nursing facility (SNF) coverage for short-stay rehabilitation in nursing homes (NHs) at a better rate than Medicaid covers long-term NH care. National trends of increasing Medicare days culminated in 2010/2011 with a reduction to the SNF rates. Before the cuts, NHs that increased SNF days also improved outcomes for long-stay residents, including pain, pressure ulcer, and functional decline outcomes, suggesting spillover effects of SNF days. We replicated the prior study to determine how changes in SNF days and long-stay outcomes related following the rate cut. From 2011 to 2014, SNF days decreased and all three study outcomes improved. Spillover effects were not consistently observed. Decreasing SNF days was associated with increasing percentages of long-stay residents with daily pain and with decreasing percentages of long-stay residents getting pressure ulcers. Research on these associations in more recent years is needed to determine whether they persist and to inform practice.
Shock Troops and Shock Absorbers: IT Support and Emotional Labor in the Rationalizing University
Authors: Seeley J. Lotus
Published: May 2021

Drawing on 200 hours of observation at The Help Desk, an IT Support (ITS) unit at a medical school, and interviews with 30 ITS workers from across the university, this article shows how organizational-level IT rationalization was affected at the microlevel through ITS workers’ extensive emotional labor and involvement in meaning-making projects. Successful implementation required ITS workers to function as shock troops, introducing and enforcing new policies, and shock absorbers, encouraging compliance and insulating administrators from discontent about those changes. This article contributes to inhabited institutions theories of organizational change by demonstrating the importance of service workers’ interactive and emotional labor to the coupling of institutional myth, organizational policy, and the interactions and practices of constituent members.

Polybutylene terephthalate (PBT) is a semi-crystalline engineering thermoplastic polyester. PBT offers rapid molding cycles, high heat resistant, crystallinity, fatigue resistance, strength and rigidity, excellent electrical properties, creep resistance, reproducible mold shrinkage and chemical resistance. In this study, PBT was loaded with synthetic graphite and carbon fiber at different weight fractions (10–40 wt.%). PBT-based composites were fabricated by the melt mixing process by using a co-rotating twin screw extruder then thermal, mechanical and morphological properties of filled PBT composites was investigated. Weight fraction of carbon fiber (up to 30 wt.%) increases the tensile strength and flexural strength of PBT, but synthetic graphite loading decreases the tensile strength and flexural strength of PBT. The highest in-plane and through-plane thermal conductivity values were obtained as 9.24 for 40 wt.% synthetic graphite filled composite and 3.41 W/mK for 40 wt.% carbon fiber reinforced composite, respectively. Carbon fiber was found to be more effective in increasing the through-plane thermal conductivities than synthetic graphite.
Growing Up Nonprofit: Predictors of Early-Stage Nonprofit Formalization
Authors: Searing Elizabeth A. M. , Lecy Jesse D.

The nonprofit organizational life cycle literature has traditionally focused on the entry and exit processes; the intermediate organizational life stages between these bookends have received less attention. Almost half of all nonprofits at any given time operate in an early life stage with less than US$100,000 in revenue, minimal overhead spending, and no paid managers. This study examines the process by which nonprofits leave the small, informal, startup phase and begin the next life stage characterized by growth and formalization. We identify financial and organizational characteristics that predict whether the nonprofit will successfully transition out of the early and informal life stage. We find that investments in professional fundraising and access to government funds are predictive of the transition out of the start-up phase, while traditional financial predictors such as revenue concentration, equity ratio, fixed cost ratios, and the accumulation of unrestricted assets have modest to no effects.
Drink and drinking in early Jewish texts: Describing a meal in the World to Come
Authors: Bergmann Claudia D.
Published: May 2021

Both the Hebrew Bible and extrabiblical literature consider food and drink to be gifts from the deity to be enjoyed by human beings, especially when they live according to the divine laws and in moderation. When it comes to extrabiblical early Jewish texts about the meal in the World to Come, one notices a curious detail: while the World to Come is portrayed as being one of utter abundance and joy, none of the texts actually describe the righteous as drinking. References to drinking natural water, fruit being turned into drink, or any other possibility for the human consumption of liquids are simply absent from these texts. How is this to be explained? This article investigates the possible reasons for the conscious or subconscious omission of a function of the human body that is most common to all human beings.

Objectives: To understand the acceptability and feasibility of sexually transmitted infection (STI) testing during antenatal care, along with the prevalence of STIs, in Rawalpindi, Pakistan. Methods: We enrolled pregnant women seeking antenatal care and performed STI testing using Cepheid GeneXpert® CT/NG and TV kits and Alere Determine™ HIV and syphilis tests. We used interviewer-administered surveys to collect medical, social, and sexual histories. Participants testing positive for STIs and their partners were treated. Results: We enrolled 1001 women from September to December 2019. Nearly all women offered to participate in this study enrolled. Most women understood the effects an STI can have on their pregnancy (99.6%) and valued STI screening during pregnancy (98.1%). 11 women tested positive for any STI: ( Chlamydia trachomatis = 4, Neisseria gonorrhoeae = 1, and Trichomonas vaginalis = 6). Of those, six presented for a test-of-cure, and two were positive for Trichomonas vaginalis. None tested positive for HIV infection or syphilis ( n = 503). Conclusions: STI testing during antenatal care in Rawalpindi was acceptable, valued, understood, and feasible. The prevalence of STIs in pregnant women was low. Continued prevalence monitoring is warranted.
What are the drivers of high-cost HIV patients?
Authors: Krentz Hartmut B , Gill M John
Published: May 2021

We aimed to identify “high-cost” patients with HIV (PWH) and determine drivers behind higher costs. All PWH at the Southern Alberta HIV Clinic, Canada, and active in 2017 were included. Sociodemographic, clinical, and healthcare utilization data were collected. The direct care costs from the payers’ perspective including antiretroviral drugs (ARV), outpatient visits, and hospital admissions were determined for 2017. Patients’ annual total costs were grouped into top 5% (i.e., high-cost), top 20%, middle 60%, and bottom 20%. High-cost patients were older, Caucasian or indigenous Canadian, and more likely acquired HIV from intravenous drug use (all p < 0.05). High-cost patients had lower nadir CD4, more comorbidities, missed more clinic appointments, had more ARV interruptions, and developed more ARV resistance ( p < 0.01). The overall median cost of HIV care was US$14,064 [IQR US$13,121–US$17,883] (2017 Cdn$). High-cost patients had a median cost of US$29,902 [IQR US$27,229–US$37,891] and accounted for 14% of total costs and 84% of all inpatient costs. Hospitalizations constituted 58% of costs for high-cost patients. Although heterogeneous, high-cost patients have distinct sociodemographic and clinical characteristics driving their healthcare utilization. Addressing these social determinants of health and using novel ARV administration approaches may preserve health and save costs.
A family of Gamma-generated distributions: Statistical properties and applications
Authors: Pourreza Hormatollah , Jamkhaneh Ezzatallah Baloui , Deiri Einolah
Published: May 2021

In this paper, we concentrate on the statistical properties of Gamma-X family of distributions. A special case of this family is the Gamma-Weibull distribution. Therefore, the statistical properties of Gamma-Weibull distribution as a sub-model of Gamma-X family are discussed such as moments, variance, skewness, kurtosis and Rényi entropy. Also, the parameters of the Gamma-Weibull distribution are estimated by the method of maximum likelihood. Some sub-models of the Gamma-X are investigated, including the cumulative distribution, probability density, survival and hazard functions. The Monte Carlo simulation study is conducted to assess the performances of these estimators. Finally, the adequacy of Gamma-Weibull distribution in data modeling is verified by the two clinical real data sets.

Linking Individual Demographics to Antecedents of Mobile Banking Usage: Evidence from Developing Countries in Southeast Europe
Authors: Çera Gentjan , Khan Khurram Ajaz , Solenički Martina
Published: May 2021

This study investigates the linkages between the antecedents of the extended unified theory of acceptance and use of technology (UTAUT2) model and an individual demographics in four developing countries in Southeast Europe. Three unexplored linkages are introduced, such as employment status, living settlement and financial experience. The article applies the partial least square and non-parametric methods to examine the proposed associations from a dataset of 959 individuals. Evidence reveals that those individuals who are employed, live in urban areas, and have financial experience scored higher in the UTAUT2 constructs. The article suggests the inclusion of additional moderating factors into the UTAUT2 model, which gives a better understanding of the individuals’ technology adaption to scholars and practitioners.
Financial Access of Latin America and Caribbean Firms: What Are the Roles of Institutional, Financial, and Economic Development?
Authors: Chu Lan Khanh
Published: May 2021

This article examines the impact of institutional, financial, and economic development on firms’ access to finance in Latin America and Caribbean region. Based on firm- and country-level data from the World Bank databases, we employ an ordered logit model to understand the direct and moderating role of institutional, financial, and economic development in determining firms’ financial obstacles. The results show that older, larger, facing less competition and regulation burden, foreign owned, and affiliated firms report lower obstacles to finance. Second, better macro-fundamentals help to lessen the level of obstacles substantially. Third, the role of institutions in promoting firms’ inclusive finance is quite different to the role of financial development and economic growth.
