DIFFERENTIAL NITROGEN AND PHOSPHORUS RETENTION BY FIVE WETLAND PLANT SPECIES

Abstract Riparian wetlands have a demonstrated ability to filter and control nitrogen (N) and phosphorus (P) movement into streams and other bodies of water; few studies, however, have examined the roles that individual plant species serve in sequestering N and P pollutants. We evaluated the potential for growth and consequent N and P accumulation by five species of wetland perennials. We planted blocks consisting of 900-cm2 plots of each species at 11 sites within a riparian wetland that receives large inputs of agricultural runoff. Plant shoots and roots were collected at the time of peak standing crop to determine net accumulation of biomass, N, and P for one growing season. A portion of the plant shoots was placed in decomposition litterbags in the field to determine biomass, N, and P losses for 60, 120, and 150 days. Of the five species, bur reed (Sparganium americanum) had the greatest aboveground accumulation of N and P but had the lowest belowground accumulation values. In contrast, woolgrass (Sci...
The post-2015 development agenda and South-South and triangular cooperation - How the partnership model should be?

South–South and triangular cooperation as a partnership model for the post-2015 development agenda In the Outcome Document of the United Nations Conference on Sustainable Development,1 it was decided to create an Open Working Group (OWG) to propose new development goals after 2015 replacing the Millennium Development Goals.2 The OWG report specifically mentions South–South and triangular cooperation in the Goal 17 entitled ‘Strengthen the means of implementations and revitalise the global partnership for sustainable development’, under the topic of ‘technology’ and ‘capacity-building’. The UN Secretary-General issued a synthesis report on the post-2015 sustainable development agenda,3 which highlighted the establishment of new institutions of South–South cooperation, such as the BRICS Development Bank and the Asian Infrastructure Investment Bank, as new opportunities to finance investments in sustainable development. It also mentions that South–South cooperation and the significant efforts of solidarity by emerging economies is encouraging. More countries will need to commit to increasing their contribution to international public financing and set targets and timelines to do so. In turn, South–South technical assistance and the sharing of experiences through regional forums should be promoted.4 As such, South–South cooperation features as a way to unite efforts of the Global South for development, through knowledge and technology transfer and mutual capacity-building efforts,5 while triangular cooperation involves Southern-driven partnerships between two or more developing countries supported by a developed country(ies)/or multilateral organisation(s) to implement development cooperation programmes and projects.6 Here, the role of developed countries and or multilateral organisations could be to provide financial support to South–South cooperation, facilitate match-making among solution seekers and providers, to provide additional options for knowledge and technology based on its own development experience, and share its expertise on management of development cooperation initiatives with triangular cooperation partners.7 Triangular cooperation has a clear potential not only to play an important role in sustainable development trajectories, but also to be a model for global partnership for sustainable development for the next 15 years. In this context, the following three questions arise: what role could regional fora and financing mechanisms potentially play in implementing the SDGs? What experiences of a regional and inter-regional approach can be built on towards these ends? And what does triangular cooperation mean in the context of global partnership for sustainable development?
Ultra High-Resolution FDTD Modeling of a High-Performance VLSI Package for Identifying Resonances and Coupling

It is becoming increasingly important to computationally predict, study, and prevent electromagnetic compatibility (EMC) issues arising within and between ICs and other components comprising portable electronic devices. Here, we conduct a phenomenological study involving an ultra high-resolution, three- dimensional finite-difference time-domain (FDTD) model of a sample IC package having over one billion grid cells. Specifically, we determine the resonances and coupling patterns arising within the highly complex IC package. The frequency range of interest extends from 100 MHz to 7 GHz. Results indicate that the arrangement and geometry of the separate power, ground, and signaling networks comprising the IC package greatly influences the electromagnetic behavior within different regions of the package.

Colonial "Others" and Nationalist Politics in Malaysia

Recent debates on nationalism suggest that we should revisit the connection between ethnic identity and the nation, and the difficulties confronting post-colonial societies like Malaysia's in their efforts to construct a unifying nationalist project. How and why has official Malaysian nationalism reinforced ethnic identity even as it seeks a programmatic alternarive to colonial strategies in inscribing the body of the nation? Arguing that the social construction of ethnicity under colonial rule has significant implications for the nation, the article explores how colonial rule shapes nor only the consciousness of a European 'self' distinct from a colonized 'other', but also difference in the other which plays our in nationalist politics. Recent shifts in nationalist discourse reflect changes in the Malaysian social structure and suggest the possibility of a more unifying political discourse centered around the nation although it is too early to tell if it will decenter ethnic identity. Key word s: Colonialism, nationalism, ethnicity, Malaysia, politics ABSTRAK Perdebatan kebelakangan ini mengenai nasionalisme menunjukkan bahawa kita perlu mengkaji semula hubungan antara identiti etnik dengan nasion, dan kesukaran-kesukaran yang dihadapi masyarakat pasca-kolonial seperti Malaysia dalam usaha mereka untuk membina suatu projek nasionalis yang menyatukan. Bagaimana dan kenapa nasionalisme rasmi Malaysia mengukuhkan identiti etnik sekalipun ia berusaha mewujudkan satu alternatif programatik kepada strategi kolonial dalam memaktubkan jasad nasion? Bertolak daripada hujah bahawa konstruksi sosial etnisiti di bawah pemerintahan penjajah mempunyai implikasi penting bagi nasion, artikel ini menelusuri bagaimana pemerintahan penjajah membentuk bukan sahaja kesedaran 'diri' sebagai orang Eropah yang berbeza daripada orang lain, yakni yang terjajah, akan tetapi juga menelusuri perbezaan di pihak orang lain, yang menjelma dalam politik nasionalis. Perubahan dalam wacana nasionalis kebelakangan ini mencerminkan perubahan dalam struktur masyarakat Malaysia dan menunjukkan kemungkinan munculnya satu wacana politik yang lebih menyatukan yang berpusarkan idea nasion. Walau bagaimanapun, ia masih terlalu awal untuk menyatakan sama ada perubahan ini akan menyahpusatkan identiti etnik. Kata kunci: Penjajahan, nationalisme, etnisiti, Malaysia, politik
Bottling Up Innovation in Craft Brewing: A Review of the Current Barriers and Challenges

"Build a better mousetrap," the old saying goes, "and the world will beat a path to your door." Brew a better beer, however, and regulators will tie your door shut with red tape. Start-ups in the craft brewing industry face formidable barriers to entry in the form of federal, state, and local regulations. These barriers limit competition and innovation, reducing consumer welfare.While customers and new entrants are harmed, these regulations can be a privilege to incumbent firms and industries. There are various political and historical reasons for the persistence of these rules, despite the fact that they lack economic justification. Policymakers interested in economic development should eliminate regulations to help firms overcome confusing and unnecessary barriers to entry and to level the playing field between established firms and their newer, smaller rivals.
Proton coupling to [4Fe-4S](2+/+) and [4Fe-4Se](2+/+) oxidation and reduction in a designed protein.

The coupling of a single proton to [4Fe-4S]2+/+ oxidation/reduction in a de novo designed iron−sulfur protein maquette is presented. The reduced state pKared is 9.3, and the oxidized state pKaox is <6.5. The reduced state pKared shifts to 8.3 upon incorporation of a [4Fe-4Se]2+/+ cluster, implicating the cluster itself or its primary coordination sphere as the proton-coupling site.

Antitoxic immunity to cholera in isolated perfused canine ileal segments.

Canine small bowel responds to intraluminal challenge with cholera enterotoxin by increasing the net movement of isotonic fluid into the lumen of the bowel [1]. Antitoxic immunity has been demonstrated both in intact dogs challenged with Vibrio cholerae by the orogastric route and in canine Thiry-Vella fistulae challenged with cholera enterotoxin via the intraluminal route [2]. In both of these models protection was associated with an elevation in circulating antitoxin, but no attempt was made to assess the possible role of intrinsic immunity of the bowel itself. Other investigators have suggested that a major source of protection against colonization by V. cholerae rests with the mucosal cell itself [3] or with coproantibody produced by the bowel [4]. This report describes a new technique of investigating the separate effects of circulating and local antitoxic immunity in the canine small bowel. Preliminary data about the relative effectiveness of these 2 proposed mechanisms in protection from challenge with cholera enterotoxin are also reported.
Marker features for malignancy in ectocervical cells. Statistical evaluation.

Marker features for malignancy have recently been observed in ectocervical cells, even in cells that are visually normal in appearance. This study assessed the statistical significance of these marker features using a mixed-model nested-design analysis of variance (ANOVA). Features in blue intermediate cells from patients with normal cytology, moderate dysplasia, and severe dysplasia/carcinomain situ, nonkeratinizing cells from patients with moderate dysplasia, severe dysplasia/carcinomain situ, and invasive cancer, and dysplastic cells from areas of metaplasia from patients with moderate dysplasia, severe dysplasia/carcinomain situ, and invasive cancer were tested. ANOVA clearly demonstrated that the marker features differentiate between cells of the same cell type originating from patients in different diagnostic categories. In every instance, the differences owing to the diagnostic category were statistically significantly greater than those caused by patient-to-patient variability. Although the discriminating marker features in the intermediate cells were almost exclusively spectral features reflecting staining differences, morphometric features were also marker features in the dysplastic cells.
Longitudinal Study of the Six Degrees of Freedom Cervical Spine Range of Motion During Dynamic Flexion, Extension, and Rotation After Single-level Anterior Arthrodesis.

Study design A longitudinal study using biplane radiography to measure in vivo intervertebral range of motion (ROM) during dynamic flexion/extension, and rotation. Objective To longitudinally compare intervertebral maximal ROM and midrange motion in asymptomatic control subjects and single-level arthrodesis patients. Summary of background data In vitro studies consistently report that adjacent segment maximal ROM increases superior and inferior to cervical arthrodesis. Previous in vivo results have been conflicting, indicating that maximal ROM may or may not increase superior and/or inferior to the arthrodesis. There are no previous reports of midrange motion in arthrodesis patients and similar-aged controls. Methods Eight single-level (C5/C6) anterior arthrodesis patients (tested 7 ± 1 months and 28 ± 6 months postsurgery) and six asymptomatic control subjects (tested twice, 58 ± 6 months apart) performed dynamic full ROM flexion/extension and axial rotation whereas biplane radiographs were collected at 30 images per second. A previously validated tracking process determined three-dimensional vertebral position from each pair of radiographs with submillimeter accuracy. The intervertebral maximal ROM and midrange motion in flexion/extension, rotation, lateral bending, and anterior-posterior translation were compared between test dates and between groups. Results Adjacent segment maximal ROM did not increase over time during flexion/extension, or rotation movements. Adjacent segment maximal rotational ROM was not significantly greater in arthrodesis patients than in corresponding motion segments of similar-aged controls. C4/C5 adjacent segment rotation during the midrange of head motion and maximal anterior-posterior translation were significantly greater in arthrodesis patients than in the corresponding motion segment in controls on the second test date. Conclusion C5/C6 arthrodesis appears to significantly affect midrange, but not end-range, adjacent segment motions. The effects of arthrodesis on adjacent segment motion may be best evaluated by longitudinal studies that compare maximal and midrange adjacent segment motion to corresponding motion segments of similar-aged controls to determine if the adjacent segment motion is truly excessive. Level of evidence 3.
Renal Artery Embolism: Therapy With Intra-arterial Streptokinase Infusion

AbstractIntra-arterial infusion of streptokinase was used successfully to dissolve a 7-day-old main renal artery embolus in a 49-year-old woman. Renal artery patency was documented after 18 hours of thrombolytic therapy and secondary hypertension was ameliorated. Selective, intra-arterial fibrinolytic therapy may obviate the need for surgical embolectomy in poor risk patients in whom operative mortality rates appear unacceptably high.
Chapter 4 – Fabrication of Microscale Hydrogels for Tissue Engineering Applications

Microscale hydrogels are potentially useful materials for controlling cellular behavior to mimic native microenvironments for tissue engineering applications. In this chapter, various fabrication techniques to generate microscale hydrogels and their applications in tissue engineering have been outlined. In addition, we provide examples of microscale hydrogels with different physical and chemical properties for generation of tissue constructs. Finally, we discuss potential future directions in fabrication of hydrogels to address challenges in tissue engineering. It is expected that these techniques will enable engineering of three-dimensional (3D) structures with controlled features for the formation of functional tissues and organs.
A Comparison of the Minimal-Touch Technique and the Eversion Technique for Microvascular Anastomosis in a Rat Model.

Background During microvascular anastomosis, needle placement is facilitated by inserting the tips of the forceps into the lumen of the vessel, rather than grasping and everting the luminal wall, to minimize trauma to the vessel. This study examines whether the vessel wall can be grasped and everted during microvascular anastomosis without compromising surgical outcomes. Methods A total of 20 Sprague–Dawley rats weighing between 252 and 483 g were used. Bilateral anastomoses of the animals' femoral arteries (mean size: 0.90 mm) were performed using two different techniques: the classic minimal-touch approach and the eversion technique. The first 10 animals were survived for 48 hours and the second 10 animals were survived for 2 weeks. Patency was assessed immediately after surgery and just before sacrifice. Hematoxylin and eosin stains were performed and each anastomosis scored according to a grading rubric assessing endothelial cell loss, neointimal proliferation, medial necrosis, adventitial inflammation, and inflammation thickness. Results The patency rates of both techniques were identical (100%). There was no difference in the patency rates of anastomoses evaluated 48 hours after surgery (100%) and 2 weeks after surgery (100%). Histological outcomes between the minimal-touch technique and the eversion method were similar. The thickness of adventitial inflammation at 2 weeks was the only outcome found to be statistically different ( p = 0.046) between the two treatments and this difference favored the eversion technique (i.e., less inflammation thickness). Conclusion The eversion method of performing microvascular anastomosis provides comparable results to the classic minimal-touch approach in rat femoral artery anastomoses.

Secular obliquity variations of Ceres and Pallas

Abstract We examine variations in the orientations of the orbit poles and spin poles of Ceres and Pallas, on time scales of a few million years. We consider these two bodies together because they have similar orbits, but very different present states of knowledge concerning internal mass distribution and spin pole orientation. For Ceres, the Dawn mission has recently provided accurate estimates of the current spin pole orientation, and the degree 2 spherical harmonics of the gravitational potential. The polar moment of inertia is not as well constrained, but plausible bounds are known. For Pallas, we have estimates of the shape of the body, and spin pole orientation and angular rate, all derived from optical light curves. Using those input parameters, and the readily computed secular variations in the orbit pole, we can compute long term variations in the spin pole orientation. This provides information concerning long term variations in insolation, which controls stability of surface volatiles.
Comparison of conduit vessel and resistance vessel reactivity: influence of intimal permeability

Arterioles of hamster cheek pouches are less reactive to luminal application of small hydrophilic agents than to adventitial application. To explore possible longitudinal variations in response sidedness, we compared reactivity of isolated vessels from carotid arteries to first-order arterioles. Concentration-response curves for luminally or adventitially applied phenylephrine (PE) were constructed. Arterioles were 274-fold less responsive when PE was in luminal vs. adventitial responsiveness decreased as vessel diameters increased, from 24-fold in inferior saccular arteries to 18-fold in external maxillary arteries and, finally, to 3-fold in common carotid arteries. Differences in response to luminal or adventitial application of PE could be eliminated in arterioles by perfusion with 3-[(3-cholamidopropyl)-dimethylammonio]-1-propanesulfonate (CHAPS), which disrupts membrane integrity. Treatment with CHAPS also increased the transmural movement of sodium fluorescein across arteriolar vessel walls. We conclude that a diffusion barrier exists in arterial walls, that there is a longitudinal variation in this barrier as expressed by the differences in movement of small hydrophilic molecules from lumen to smooth muscle cell layers, and that the site of the barrier is likely to be at the endothelial cell membrane.
Metformin attenuates ER stress–induced mitochondrial dysfunction

Endoplasmic reticulum (ER) stress, a disturbance of the ER function, contributes to cardiac injury. ER and mitochondria are closely connected organelles within cells. ER stress contributes to mitochondrial dysfunction, which is a key factor to increase cardiac injury. Metformin, a traditional anti-diabetic drug, decreases cardiac injury during ischemia-reperfusion. Metformin also inhibits ER stress in cultured cells. We hypothesized that metformin can attenuate the ER stress-induced mitochondrial dysfunction and subsequent cardiac injury. Thapsigargin (THAP, 3 mg/kg) was used to induce ER stress in C57BL/6 mice. Cell injury and mitochondrial function were evaluated in the mouse heart 48 hours after 1-time THAP treatment. Metformin was dissolved in drinking water (0.5 g/250 ml) and fed to mice for 7 days before THAP injection. Metformin feeding continued after THAP treatment. THAP treatment increased apoptosis in mouse myocardium compared to control. THAP also led to decreased oxidative phosphorylation in heart mitochondria-oxidizing complex I substrates. THAP decreased the calcium retention capacity, indicating that ER stress sensitizes mitochondria to mitochondrial permeability transition pore opening. The cytosolic C/EBP homologous protein (CHOP) content was markedly increased in THAP-treated hearts compared to control, particularly in the nucleus. Metformin prevented the THAP-induced mitochondrial dysfunction and reduced CHOP content in cytosol and nucleus. Thus, metformin reduces cardiac injury during ER stress through the protection of cardiac mitochondria and attenuation of CHOP expression.
Ecological momentary assessment of daily discrimination experiences and nicotine, alcohol, and drug use among sexual and gender minority individuals.

Objective Sexual and gender minority (SGM) individuals experience elevated rates of minority stress, which has been linked to higher rates of nicotine and substance use. Research on this disparity to date is largely predicated on methodology that is insensitive to within day SGM-based discrimination experiences, or their relation to momentary nicotine and substance use risk. We address this knowledge gap in the current study using ecological momentary assessment (EMA). Method Fifty SGM individuals, between 18 and 45 years of age, were recruited from an inland northwestern university, regardless of their nicotine or substance use history, and invited to participate in an EMA study. Each were prompted to provide data, six times daily (between 10:00 a.m. and 10:00 p.m.) for 14 days, regarding SGM-based discrimination, other forms of mistreatment, and nicotine, drug, and alcohol use since their last prompt. Results Discrimination experiences that occurred since individuals' last measurement prompt were associated with greater odds of nicotine and substance use during the same measurement window. Substance use was also more likely to occur in relation to discrimination reported two measurements prior in lagged models. Relative to other forms of mistreatment, discrimination effects were consistently larger in magnitude and became stronger throughout the day/evening. Conclusion This study adds to existing minority stress research by highlighting the both immediate and delayed correlates of daily SGM-based discrimination experiences. These results also contribute to our understanding of daily stress processes and provide insight into ways we might mitigate these effects using real-time monitoring and intervention technology.

Adverse obstetric outcomes during delivery hospitalizations complicated by suicidal behavior among US pregnant women.

Objective The effects of suicidal behavior on obstetric outcomes remain dangerously unquantified. We sought to report on the risk of adverse obstetric outcomes for US women with suicidal behavior at the time of delivery. Methods We performed a cross-sectional analysis of delivery hospitalizations from 2007–2012 National (Nationwide) Inpatient Sample. From the same hospitalization record, International Classification of Diseases codes were used to identify suicidal behavior and adverse obstetric outcomes. Adjusted odds ratios (aOR) and 95% confidence intervals (CI) were obtained using logistic regression. Results Of the 23,507,597 delivery hospitalizations, 2,180 were complicated by suicidal behavior. Women with suicidal behavior were at a heightened risk for outcomes including antepartum hemorrhage (aOR = 2.34; 95% CI: 1.47–3.74), placental abruption (aOR = 2.07; 95% CI: 1.17–3.66), postpartum hemorrhage (aOR = 2.33; 95% CI: 1.61–3.37), premature delivery (aOR = 3.08; 95% CI: 2.43–3.90), stillbirth (aOR = 10.73; 95% CI: 7.41–15.56), poor fetal growth (aOR = 1.70; 95% CI: 1.10–2.62), and fetal anomalies (aOR = 3.72; 95% CI: 2.57–5.40). No significant association was observed for maternal suicidal behavior with cesarean delivery, induction of labor, premature rupture of membranes, excessive fetal growth, and fetal distress. The mean length of stay was longer for women with suicidal behavior. Conclusion During delivery hospitalization, women with suicidal behavior are at increased risk for many adverse obstetric outcomes, highlighting the importance of screening for and providing appropriate clinical care for women with suicidal behavior during pregnancy.
Time-constrained anycast routing under short contact duration in delay-tolerant networks

Delay-tolerant networks (DTNs) are sparse mobile ad hoc networks, in which there is typically no complete path between the source and destination. Anycast is an important group communication paradigm for numerous DTN applications such as resource discovery and information exchange in emergency or crisis situations. Unlike unicast and multicast, which have been studied extensively in DTNs, few prior works have addressed the DTN anycast routing problem. Furthermore, they often ignore the time constraint and assume long contact durations in formulating the relay selection strategy. In this paper, we study a single-copy time-constrained anycast (TCA) routing under short contact duration. We address two key issues: (1) to which next hop relay node should messages be forwarded and (2) in which order should messages be forwarded. To reduce the transmission cost, we select relay nodes from both current and past contacts based on the one-hop and two-hop delivery probabilities, respectively. We derive the delivery probability from the distribution of inter-contact time and contact duration time. We address the case of exponential and Pareto distribution, which are the most popular assumptions in literature. For the message scheduling, messages with the highest delivery probability are prioritized to be transmitted first. Extensive simulation results based on Cabspotting and MIT Reality traces show that our scheme can achieve up to 29% higher delivery rate, 24% lower delay, and 36% lower transmission cost compared to other anycast routing strategies.
Apotheosis of the Batman? Symbolism and Allegory in Batman: The Return of Bruce Wayne

At the end of Grant Morrison’s Batman: The Return of Bruce Wayne, the eponymous character spends two minutes frozen and clinically dead. At the start of the book, his friends had only just learned that he was still alive. Bruce emerges from this ordeal on the final page of the comic, grimly determined to resume his lifelong war on crime and corruption. He’s been brainwashed, killed a » god, « been catapulted into pre-history and then all the way to the end of the universe before returning to the present and spending two minutes on ice.
On the Effects of Wind Tunnel Turbulence on Steady and Unsteady Airfoil Characteristics

Real life aerodynamics is time dependent by nature. For example, helicopter and gas turbine blades operate in the wakes of the previous blades, vortices can shed off the leading edge of a delta wing inducing velocities on the entire wing, and aerodynamic bodies may flutter causing very unsteady loading and unsteady shed vortex fields.
Experimental and Analytical Methods for Assessing Bearing Performance Under Debris Contaminated Lubrication Conditions

Debris particle contamination in lubricants is a major cause of premature bearing and gear failure, responsible for causing accompanying costs in equipment downtime, warranty claims, and lost productivity. Various experimental and predictive methods have been developed to assist design engineers in analysis and development of equipment that is less sensitive to such contamination. This paper provides an overview of debris particle contamination in lubricants. It also presents new data that compares bearing life test results and predictive analysis methods for various tapered roller bearings operating under debris-contaminated conditions. As a baseline, some previous work in these areas is briefly summarized and referenced. More recent work has refined one analytical method (using a surface characterization technique), correlated this method with bearing test lives in debris conditions, and pointed to design and manufacturing modifications in the bearings themselves. This has resulted in designs that improve bearing life in debris-contaminated environments.
Label-free Identification of Antibody-mediated Rejection in Cardiac Allograft Biopsies Using Infrared Spectroscopic Imaging.

Background Antibody-mediated rejection (AMR) in cardiac allograft recipients remains less well-understood than acute cellular rejection, is associated with worse outcomes, and portends a greater risk of developing chronic allograft vasculopathy. Diffuse immunohistochemical C4d staining of capillary endothelia in formalin-fixed, paraffin-embedded right ventricular endomyocardial biopsies is diagnostic of immunopathologic AMR but serves more as a late-stage marker. Infrared (IR) spectroscopy may be a useful tool in earlier detection of rejection. We performed mid-IR spectroscopy to identify a unique biochemical signature for AMR. Methods A total of 30 posttransplant formalin-fixed paraffin-embedded right ventricular tissue biopsies (14 positive for C4d and 16 negative for C4d) and 14 native heart biopsies were sectioned for IR analysis. Infrared images of entire sections were acquired and regions of interest from cardiomyocytes were identified. Extracted spectra were averaged across many pixels within each region of interest. Principal component analysis coupled with linear discriminant analysis and predictive classifiers were applied to the data. Results Comparison of averaged mid-IR spectra revealed unique features among C4d-positive, C4d-negative, and native heart biopsies. Principal component analysis coupled with linear discriminant analysis and classification models demonstrated that spectral features from the mid-IR fingerprint region of these 3 groups permitted accurate automated classification into each group. Conclusions In cardiac allograft biopsies with immunopathologic AMR, IR spectroscopy reveals a biochemical signature unique to AMR compared with that of nonrejecting cardiac allografts and native hearts. Future study will focus on the predictive capabilities of this IR signature.

Survey of Formicidae Attracted to Protein Baits on Georgia's Barrier Island Dunes

Although insects have been identified as valuable bioindicator species, insect diversity in coastal sand dunes is understudied. Our study presents the first survey focused on Georgia's barrier island ant assemblage. We surveyed the primary and secondary dunes of Cumberland, Little St. Simons, and Sapelo islands in the summers of 2016 and 2017 using protein baits to recruit scavenging ants that forage on dunes and beaches. We placed 4863 baits over the 2 sampling seasons; 2458 recruited ants. We documented 29 ant species, including 3 new records for the state: Dorymyrmex reginicula, Pheidole navigans, and Solenopsis globularia. Our survey provides a baseline for future projects to evaluate disturbance and ecosystem health on Georgia's barrier islands.
A low-cost smart home for the assistance of elderly persons and patients

Today, there is a growing interest for a combination of intelligent applications and assistive mechanisms, which aims to cover the needs of the elderly persons/patients living alone. We focus on the design and implementation of a distributed Information System used to support the elderly persons/patients at home. First, user requirements are captured, then the architecture of a distributed Information System (IS) is given, and eventually functions of the IS and the role of people involved into the system are discussed. We use new technologies and tools to implement a prototype of a low cost "smart" home, and eventually some conclusions are given.
Late-stage functionalization of BN-heterocycles

BN/CC isosterism has emerged as a viable strategy to expand the chemical space of organic molecules. In particular, the application of BN/CC isosterism to arenes has received significant attention due to the vast available chemical space provided by aromatic hydrocarbons. The synthetic efforts directed at assembling novel aromatic BN heterocycles have resulted in the discovery of new properties and functions in a variety of fields including biomedical research, medicinal chemistry, materials science, catalysis, and organic synthesis. This tutorial review specifically covers recent advances in synthetic technologies that functionalize assembled boron-nitrogen (BN) heterocycles and highlights their distinct reactivity and selectivity in comparison to their carbonaceous counterparts. It is intended to serve as a state-of-the-art compendium for readers who are interested in the reaction chemistry of BN heterocycles.
Separate but not equal: Toward a nomological net for migrants and migrant entrepreneurship

This paper considers migrants on a continuum in terms of voluntariness of departure and intended timeframe in the new location. The corresponding 2 × 2 framework offers a theory-driven typology with which to consider four groups: exiles, sojourners, immigrants, and refugees. We apply the framework to the topic of migrant entrepreneurship, demonstrating the need for separate consideration of refugee and immigrant entrepreneurs. We propose ways in which types of capital differ between the two and discuss how differences affect entrepreneurial endeavors. The framework extends scholarship on migrant entrepreneurship, while providing a nomological net for improved theorizing for a range of migrant situations.

INTEGRATED CHANGE MANAGEMENT AND PROJECT MANAGEMENT STRATEGIC FRAMEWORK PART II: LESSONS LEARNED FROM A LARGE DIGITAL TRANSFORMATION UTILIZING THIS FRAMEWORK

In late 2018, we published an article in this journal outlining a theoretical approach to an integrated change management and project management strategic framework. (Dicianno & Gigliotti, 2018). The details of this framework were an integral part of a digital transformation disrupting our managers and employees as part of technology change with our Human Resource Information System (HRIS). There had not been a technology change in this space in over 25 years and this strategic framework provided us with a solid foundation for managing such a large change. However, it did not come with several lessons learned along the way and a follow-up article was necessary to continually improve on this strategic framework and allow other practitioners and change experts to learn the same lessons we learned while implementing this strategic approach. In this follow-up article, we shared key lessons learned during this large digital transformation to build on the framework in the previous article. We hope this would be a springboard for the future of digital transformations seeking to utilize the integrated change management and project management approach.

Can patients independently identify their urinary incontinence symptoms

The objective of our study is to compare patient self-reported urinary incontinence symptoms based on the International Consultation on Incontinence Questionnaire- Short Form (ICIQ-SF) question number 6 (When does urine leak?) with physician-assessed interpretation of the patient’s urinary incontinence symptoms. This trial is a cross-sectional study of patients who presented to a tertiary urogynecology center with symptoms of urinary incontinence between January 2014 and August 2016. We compared patient-reported symptoms on the ICIQ-SF with physician interpretation of urinary complaints during their initial visit. The urinary incontinence symptoms included stress urinary incontinence (SUI), urgency urinary incontinence (UUI), insensible urine loss, nocturnal enuresis, and post-micturition dribbling. A total of 432 patients with a mean age of 61 were included in this evaluation. The most common urinary incontinence symptoms according to the physician were UUI (n = 357, 83%), followed by SUI (n = 308, 71%). Of the patients who were diagnosed by a physician with the symptom of UUI, only 61% self-identified as having this symptom based on the ICIQ-SF, and for SUI, only 66% self-identified as having SUI symptoms based on the ICIQ-SF. Overall UUI (κ = 0.30) appears to have poor agreement, as does nocturnal enuresis (κ = 0.39), when compared with physician historical assessment. There is a discrepancy between patient-reported urinary incontinence symptoms on the ICIQ-SF and physician-assessed symptoms. Symptomatology entered into electronic medical records by patients is often inaccurate. Physician validation is essential in understanding the underlying the precise symptomatology.
Characteristics of random responders in a financial risk-tolerance questionnaire

The possibility of random response occurring, which can result in Type II errors, is possible whenever a financial risk-tolerance questionnaire is administered. This study was designed to apply inter-item standard deviation (ISD) scores, as introduced by Marjanovic, Holden, Struthers, Cribbie, and Greenglass (2015), to identify responders to a financial risk-tolerance questionnaire as hyper-consistent, conscientious, or random. Hyper-consistent responders were found to be more likely to be older married men who make their own financial and investment decisions. Those classified as hyper-consistent exhibited the lowest risk-tolerance scores. Conscientious responders were more likely to report having a high level of attained education and to rely on someone else when making financial and investment decisions. Financial risk-tolerance scores for conscientious responders fell between scores for hyper-consistent and random responders. Random responders were found to be younger, single, less well educated, and more likely to hold cash in their portfolio. Random responders also exhibited the highest financial risk-tolerance scores among participants in this study.
37 Leading systems change through co-production with beneficiaries and champions from multiple sectors

Background Social disadvantage is associated with problems in child development and studies have found this was largely mediated by maternal mental health (Ban et. al, 2012). In Southwark, 40% of children live in poverty and 30–40% of GP visits were mental health related. Yet, there is a shortage of mental health support services for their population even before the surge in demand triggered by Covid-19. Given this backdrop, support for parental mental health should be more distributed in the wider society, utilising preventative community approaches for mental well-being, particularly for disadvantaged parents. Leadership intervention Combining principles of design thinking and co-production, the root causes of the problem of maternal and more broadly, parental distress, were investigated through focus group, individual interviews, clinical observations and preliminary data from primary care database. People considered to be important in the parents’ network of influence were then invited to ‘parent champions’ co-production sessions over zoom where champions were asked to co-design and co-deliver ways to better meet these needs. A total of 4 sessions were held to date with 60 champions from 13 sectors. Outputs Interventions co-produced from the multi-sector parent champions events include expanding a computer bank for the digitally deprived, developing culturally sensitive GP video briefings to address parents’ concern about Covid-19, and building a buddy system between parent champions and social prescribers. Process outcomes 85% of the parent champions said they would do one thing differently to support self or other parents as as result of conversations during co-production. 60% said they feel more connected and less alone in coping with the crisis through the co-production process. Leadership learning When diverse and relevant people are involved in co-production, synergy happens, creating a higher point of leverage for wider impact.
Application of Multimedia Education System Under Clustering Algorithm in Value Orientation of College Students

College students are the precious wealth of the country, the builders and successors of the socialist cause. How to guide college students to establish a correct world outlook, outlook on life and values is very important and of great practical significance. In the teaching practice of guiding college students’ value orientation, multimedia technology has been fully utilized, which is the inevitable trend of the development of higher education. The emergence of multimedia teaching has not only changed the study and thinking habits of college students in the past, but also brought new challenges to the value orientation of college students to a certain extent. Therefore, in order to improve the efficiency of College Students’ value orientation education, it is necessary to study the influence of multimedia teaching on Contemporary College Students’ value orientation education from many aspects. Based on this, this paper analyzes the importance of the value orientation education of contemporary college students, discusses the current situation and existing problems of the value orientation education of contemporary college students, and on this basis discusses the specific impact of multimedia teaching on the value orientation education of contemporary college students, in order to provide some beneficial basis for future research.
Data-Driven Quadratic Stabilization of Continuous LTI Systems

Abstract This paper introduces a simple data-driven quadratic stabilization control (DDQSC) method to design a state feedback controller based solely on experimental measurements while avoiding explicitly identifying the plant. Rather, we seek a controller guaranteed to quadratically stabilize all plants that could have possibly generated the observed data. While in principle this leads to a very challenging non-convex robust optimization problem, our main result provides a convex, albeit infinite-dimensional, necessary and sufficient condition for the existence of such a controller and its associated Lyapunov function. In the second part of the paper, we provide a tractable finite-dimensional convex relaxation of this condition and illustrate its effectiveness with several examples.
Herd medicine in perspective

Veterinarians in the United States are currently evaluating their professional activities in order to serve the livestock producer and food consumer more effectively. Planned health programs are only partially effective if environmental and management deficiencies are not identified and corrected. This is accomplished most effectively by an interdisciplinary approach between veterinary medicine and agricultural engineering. This highly effective approach has been utilized at the University of Minnesota, College of Veterinary Medicine for over 20 years. Dairy producers on this program presently realize an economic benefit of over $20.00 in return for each dollar invested in total animal health care, environmental and management systems.
Single Fathers with Daughters in American Film

This chapter examines how U.S. films of the 2010s reflect evolving notions of fatherhood in a rapidly changing society, as represented by feature films focusing on a father–daughter relationship. Earlier in the decade, larger-budget films typically contain tropes already identified by Hannah Hamad as typical of U.S. fatherhood films in a postfeminist era: a father involved in public as well as private paternalism, who undergoes a learning curve to achieve a more domestic competence and emotional sensitivity. But lower-budget films increasingly experiment with alternative notions of fatherhood, examining fathers who live outside the mainstream or who have already achieved domestic competence. These low-budget experiments, often written or directed by young filmmakers, suggest a possibility of moving away from traditional gender paradigms and toward more gender-neutral cinematic configurations of family.
Electric Field Decay Without Pair Production

Electric fields can spontaneously decay via the Schwinger effect, the nucleation of a charged particle-anti particle pair separated by a critical distance $d$. What happens if the available distance is smaller than $d$? Previous work on this question has produced contradictory results. Here, we study the quantum evolution of electric fields when the field points in a compact direction with circumference $L < d$ using the massive Schwinger model, quantum electrodynamics in one space dimension with massive charged fermions. We uncover a new and previously unknown set of instantons that result in novel physics that disagrees with all previous estimates. In parameter regimes where the field value can be well-defined in the quantum theory, generic initial fields $E$ are in fact stable and do not decay, while initial values that are quantized in half-integer units of the charge $E = (k/2) g$ with $k\in \mathbb Z$ oscillate in time from $+(k/2) g$ to $-(k/2) g$, with exponentially small probability of ever taking any other value. We verify our results with four distinct techniques: numerically by measuring the decay directly in Lorentzian time on the lattice, numerically using the spectrum of the Hamiltonian, numerically and semi-analytically using the bosonized description of the Schwinger model, and analytically via our instanton estimate.
Semi-empirical model of deposit size and porosity in 420 stainless steel and 4140 steel using laser engineered net shaping

Abstract Laser engineered net shaping (LENS™) samples were fabricated from two technologically important steel alloys, 420 and 4140, in order to study how processing parameters such as powder feed rate and laser traverse velocity affected porosity and deposit dimensions. For both steels, it was found that many possible combinations of laser traverse velocity and powder feed rate will result in negligible porosity provided that the ratio of powder feed rate to laser traverse velocity does not exceed a maximum level. Based on measurements of deposit size and shape in the various experiments, a semi-empirical model is presented that predicts the trend in deposit sizes for various processing parameters.
