Place-Based Small Business Support and its Implications for Neighborhood Revitalization

Policy makers utilize various place-based interventions to reduce spatial inequality. In particular, there has been increasing attention to supporting small businesses in distressed places, but the lack of evidence makes it difficult to justify these public investments. The author investigates the Neighborhood Opportunity Fund (NOF), which has been providing grants for physical improvements to businesses in a low-income part of Chicago since 2017. Event studies are used to quantify the program's impacts on new business licenses, jobs, building permits, the commercial real estate market, and crime. The NOF increased construction and remodeling activity and decreased narcotics crimes around establishments receiving grants. Under some circumstances, it led to new business formation and increased demand for real estate. However, no evidence was found of a relationship between the NOF and jobs or total crimes in the larger area. This study is the first step to understanding how place-based small-business support programs affect neighborhoods.
Compensation-Based Cooperative MFAILC for Multiple Subway Trains Under Asynchronous Data Dropouts

This paper researches the cooperative control problem for multiple subway trains under the asynchronous data dropouts in both measurement channel and downlink channel. The compensation-based cooperative model free adaptive iterative learning control (cCMFAILC) for the multiple city subway trains (MCSTs) is proposed to avoid deterioration of the control performance due to data dropouts. First, the nonlinear subway train system is transformed into an equivalent dynamic linearization data model to describe the input-output dynamics of the subway train system. Next, the lost data is replaced by the corresponding data of the same time instant in the latest available iteration. And the cCMFAILC is designed to guarantee that the speed tracking errors of MCSTs are bounded along the iteration axis and the headway of neighboring subway trains is stabilized in a safe range. Finally, theoretical analysis and MCSTs simulations verify the validity of the proposed cCMFAILC scheme.
Predicting Entrepreneurial and Crowdfunding Intentions ? A Study of Romania and South Korea

Crowdfunding has recently gained ground as an alternative financing means, particularly for start-ups and risky enterprises. We hereby analyse Romanian and South Korean students' intentions to use crowdfunding in their future ventures. Using PLS-SEM (N=441), we first investigated the influence of the Theory of Planned Behaviour variables- attitudes, social norms, perceived behavioural control along with entrepreneurship education on entrepreneurial intentions. In addition, we looked into the influence of perceived trust and risk, performance expectancy, effort expectancy and facilitating conditions on crowdfunding intentions. Finally, we checked entrepreneurial intentions with crowdfunding intentions. We find that attitudes towards entrepreneurship, social norms, and entrepreneurial education have a positive influence and perceived behavioural control have a negative influence on entrepreneurial intentions. In terms of crowdfunding intentions, they were found to be positively influenced by performance expectancy, perceived trust and risk and entrepreneurial intentions. The results are useful both for educators designing higher education programmes in the field of entrepreneurship, as well as for crowdfunding platform owners in designing platform functionalities and image.
The Impact of Tumor Infiltrating Lymphocytes Densities and Ki67 Index on Residual Breast Cancer Burden following Neoadjuvant Chemotherapy

To avoid unnecessary neoadjuvant chemotherapy in case anticipating a poor therapy response, it is essential to find the pathological parameters that would predict pathological complete response or at least a decrease in tumor burden following neoadjuvant chemotherapy. The purpose of this study is to investigate the hypothesis that tumor infiltrating lymphocytes can predict the efficacy of neoadjuvant chemotherapy and to find the Ki67 cutoff value that best predicts the benefit of chemotherapy. 153 cases of breast cancer were chosen, based on their molecular subtype: triple negative subtype (77) and luminal, HER2-ve subtype (76). Histopathological assessment of pretherapy core biopsies was conducted to assess variable pathological parameters including TILs rates with the aid of immunohistochemical staining for CD20 and CD3. Moreover, core biopsies were stained for Ki67, and the findings were compared to the residual cancer burden following neoadjuvant chemotherapy. On analyzing and contrasting the two groups, a significant association between molecular subtype and pathological complete response was confirmed, while tumor-infiltrating lymphocytes in either group had no effect on therapy response. We used receiver operating characteristic curve analysis to determine that a cutoff of 36% for Ki67 is the most accurate value to predict complete therapy response.
Agrobacterium sp. ZX09 β-Glucan Attenuates Enterotoxigenic Escherichia coli-Induced Disruption of Intestinal Epithelium in Weaned Pigs

To explore the protective effect of dietary β-glucan (BGL) supplementation on intestinal epithelium exposure to enterotoxigenic Escherichia coli (ETEC), thirty-two weaned pigs were assigned to four groups. Pigs were fed with a basal diet or basal diet containing 500 mg/kg BGL, and were orally infused with ETEC or culture medium. Results showed BGL supplementation had no influence on growth performance in weaned pigs. However, BGL supplementation increased the absorption of D-xylose, and significantly decreased the serum concentrations of D-lactate and diamine oxidase (DAO) in the ETEC-challenged pigs (p < 0.05). Interestingly, BGL significantly increased the abundance of the zonula occludens-1-(ZO-1) in the jejunal epithelium upon ETEC challenge (p < 0.05). BGL supplementation also increased the number of S-phase cells and the number of sIgA-positive cells, but significantly decreased the number of total apoptotic cells in the jejunal epithelium upon ETEC challenge (p < 0.05). Moreover, BGL significantly increased the duodenal catalase (CAT) activity and the ileal total superoxide dismutase (T-SOD) activity in the ETEC-challenged pigs (p < 0.05). Importantly, BGL significantly decreased the expression levels of critical inflammation related proteins such as the tumor necrosis factor-α (TNF-α), interlukin-6 (IL-6), myeloid differentiation factor 88 (MyD88), and nuclear factor-κB (NF-κB) in the jejunal and ileal mucosa upon ETEC challenge (p < 0.05). BGL also elevated the propanoic acid content and the abundance of Lactobacillus and Bacillus in the colon upon ETEC challenge (p < 0.05). These results suggested BGL could alleviate the ETEC-induced intestinal epithelium injury, which may be associated with suppressed inflammation and improved intestinal immunity and antioxidant capacity, as well as the improved intestinal macrobiotic.
Polymorphisms in paired box 1 gene were associated with susceptibility of adolescent idiopathic scoliosis: A case–control study

Background: Association of genetic polymorphisms in paired box 1 (PAX-1) gene can influence the development of adolescent idiopathic scoliosis (AIS). PAX-1 is mainly expressed in the region of the vertebral bodies and intervertebral discs, being important for the proper formation of spinal structures. Objectives: The objective of this study was to evaluate the association of polymorphisms in PAX-1 gene with the susceptibility of AIS. Settings and Design: This was an analytical observational case–control study. Materials and Methods: Samples of 59 AIS indicated for surgical treatment, and 119 controls, without spinal disease were genotyped for PAX-1 rs6137473 and rs169311 polymorphisms. Statistical Analysis: The association of the polymorphisms with AIS was evaluated by a multivariable logistic regression model, using odds ratios (OR) and 95% confidence intervals (CI). Results: According to Lenke's classification, 89.8% had Type I and 10.2% II curves. The mean value of the Cobb angle of the proximal thoracic curve was 30.8°, 58.7° thoracic, and 30.4° for the lumbar and on the bending films 14.6°, 40.7°, and 11°, respectively. Among the AIS group, there was a predominance of females (8.8:1). The PAX-1 rs169311 and rs6137473 polymorphisms were positively associated with developing the AIS (OR = 1.98; 95% CI = 1.2–3.3 and OR = 3.16; 95% CI = 1.4–7.3, respectively). The rs6137473 polymorphism was associated with the lumbar modifier B and C compared to A (OR = 2.52; 95% CI = 1.1–5.8). Conclusions: PAX-1 polymorphisms were associated with an increased risk of developing the AIS and with curve severity and can be used as a biomarker to map the risk of developing surgical-grade AIS, guiding the treatment of patients.
Mechanical Performance of Commercially Available Premix UHPC-Based 3D Printable Concrete

Several recent studies have attempted to formulate printable cementitious materials to meet the printing requirements, but these materials are designed to work with specific printing equipment and printing configurations. This paper aims to systematically develop and perform characterization of a commercially available ultra-high-performance concrete-class material (UHPC) modified to be printable. Four percentages of superplasticizer were used (100%, 94%, 88%, 82%) to adjust the UHPC mixture for 3D-printing requirements. A superplasticizer amount of 88% was considered adequate to meet the requirements. Several fresh and hardened properties of UHPC were measured experimentally: shape-retention ability and green strength were investigated in fresh state, and compressive and flexural strength were evaluated in three loading directions to evaluate the anisotropic effects. Furthermore, the strength of the interlayer bond was investigated. The UHPC developed in this study met the criteria for extrudability, buildability, and shape retention to ensure printability. In comparison with mold-cast UHPC, printed UHPC exhibited superior flexural performance (15–18%), but reduced compressive strength (32–56%). Finally, the results demonstrated that a commercially available UHPC-class material can be used for 3DCP, which possesses all necessary properties, both fresh and hardened.
Differences in Agonistic Behavior and Energy Metabolism between Male and Female Swimming Crab Portunus trituberculatus Based on the Analysis of Boldness

Simple Summary Boldness is a widely studied personality trait that is positively related to an individual’s willingness to fight. To explore the agonistic behavior between female and male crabs with different degrees of boldness, we quantified the boldness of females and males using a behavior observation system and used the experimentally determined boldness and classification. The results showed that boldness affected the agonistic behavior between female and male swimming crabs, the fighting willingness and capacity of male crabs is higher than that of female individuals and is higher in bold crabs than in shy individuals. Energy reserves and metabolic rates may be one of the factors affecting the agonistic behavior in crabs and that the agonistic behavior resulted in significant changes in key energy metabolites. Abstract Individual differences in metabolism and agonistic behavior have been a key research area in evolution and ecology recently. In this study, we investigated the boldness of swimming crabs Portunus trituberculatus and explored the agonistic behavior between female and male crabs, specifically examining competitions between bold females vs. bold males (BF–BM), bold females vs. shy males (BF–SM), shy females vs. shy males (SF–SM), and shy females vs. bold males (SF_BM) and its relationship with energy metabolism. The main results revealed the following: There was no significant difference in boldness between females and males, while there were more bold individuals than shy in both females and males. Bold individuals initiated significantly more fights than shy individuals, and male initiators won significantly more fights than female initiators. The duration and intensity of fight between bold individuals was significantly higher than fights between shy individuals. For males, the concentration of glucose in the hemolymph was significantly higher in shy crabs than bold crabs, while there was no significant difference between shy and bold individuals in females. After fighting, the concentration of glycogen in claws was lower than that before fighting, and the concentrations of glucose and lactate in hemolymph were significantly higher after fighting than before. We found that the fighting willingness and ability were higher in male crabs than females and higher in bold crabs than shy. Fighting ability varied between sexes and was influenced by boldness and energy state.
Effect of team diversity on team cohesion in faith-based organizations

Team diversity management helps to improve the cohesion of a team and ultimately, organizational development is enhanced. The purpose of this study was to determine the effect of team diversity management on team cohesion at St. Martin Catholic Social Apostolate, Kenya. The study adopted a descriptive research design. The target population for the study was 115 employees at the St. Martin Catholic Social Apostolate in Kenya. Stratified and simple random sampling procedures were used to sample 92 employees. Data was collected using a questionnaire and the collected data was analyzed through the use of the Statistical Package for Social Scientists (SPSS) version 21. Descriptive statistical analysis involved the calculation of percentages and frequencies while inferential statistical analysis involved Pearson correlation in establishing the association of the variables under investigation. and Chi-square tests. Data was presented in the form of tables and charts. Qualitative data were analysed thematically and presented in the form of narratives. The study ensured that ethical considerations were adhered to. The study found a statistically significant relationship between team diversity management and team cohesion (p<0.05). The study concludes that each team member is held accountable for their activities and the decisions they make regarding the team and is included in team activities. The study recommends that the team leaders ensure that all team members are included in all team activities. This can be achieved through creating environments and opportunities that allow the team members to provide their opinions openly.
IS ADHD UNDER-DIAGNOSED IN BOSNIA AND HERZEGOVINA? COMPARISON OF CLINICALLY
CONFIRMED CASES VS. PARENT-REPORTED PREVALENCE OF ADHD

Attention Deficit Hyperactivity Disorder (ADHD) is a frequent neurodevelopmental disorder characterized by hyperactivity, inattention, and impul- sivity. The issue of whether ADHD is a socially constructed disorder has received much attention. The goal of the present study was to examine the clinical prevalence of ADHD in Bosnia and Herzegovina (BIH). An additional goal was to investigate the prevalence of school-aged children who fulfill the criteria for the condition but do not have a clinical diagnosis. For the first research goal, the sample consisted of five University Clinical Centers in BIH that provided data on the prevalence. For the second goal, the sample consisted of 1935 parents of children aged 6 to 15 years. Parents of 1935 school-aged children from the Federation BIH completed the questionnaire regarding ADHD symptoms. Children ranged in age from 6 to 15 years. The mean age of children was 10.2 years (SD- 2.1 years). There were 1061 girls and 874 boys in the sample. Five hospitals in the Federation BIH (4 University Clinical Centers and 1 Cantonal Hos- pital) were sent a questionnaire to provide us with information on how many school-aged children were diagnosed with ADHD and their basic demographic data. In addition, the Clinical Centers were asked to provide information on what treatment they provide to children with ADHD. The results of this study indicated that clinical diagnosis of ADHD is infrequent. The number of clinically confirmed cases of ADHD in the Federation BIH was 138 or less than 0.001%. On the other hand, accord ing to survey data, there is a prevalence rate of ADHD indicated like that observed in western countries. According to the parents’ reports, there were 97 children or 5% who fulfilled the criteria for ADHD diagnosis. In relation to gender distribution of ADHD, there were more boys (88 boys) than girls (50 girls) with a clinically confirmed diagnosis of ADHD and boys were 1.76 times more likely to have a ADHD diagnosis than were girls. On the other hand there were more girls than boys who had ADHD according to parents’ reports, but this difference, according to the Chi square test, was not statistically significant (ꭓ 2 = 0.14; p = ,70). The results of this study have clearly shown that ADHD is underdiag- nozed in Bosnia and Herzegovina. There is a huge discrepancy between the clinically diagnosed children and the parent-reported symptoms of ADHD. Given the burden that ADHD has on children and their families it should be of the utmost importance to provide timely diagnosis and proper treatment. One way to improve the current situation is through a better cooperation between school staff (psychologists, teachers), parents, and medical professionals.

Third order nondegenerate homotopies of space curves

A space curve given by a C immersion X: S —• E of the unit circle S into a Euclidean 3-space E is said to be third order nondegenerate if it has nonvanishing torsion, and of course nonvanishing curvature. Examples of such curves are coiled springs which are joined into closed curves; some telephone cords are made this way. Two such space curves are third order nondegenerately homo topic if they are connected by a 1-parameter family of such curves. (See Feldman [1] for the general definition of a pth order nondegenerate map between manifolds of arbitrary dimensions.) Theorem 1. There are four third order nondegenerate homotopy classes of space curves. Let eγ be the unit tangent vector of the curve X, respecting the orientation when that is prescribed. The spherical image or tangential indicatrix is given by the map ex\ S ι —> S, where S is the unit 2-sphere in E. It is easy to check that because the torsion of the curve X never vanishes the geodesic curvature of its spherical image is never zero. Furthermore, because the curve is closed, the spherical image must cross every great circle, or what is the same, contain the center of S in the interior of its convex hull; this observation about closed space curves is due to C. Loewner (see Fenchel [3]). Thus a 1-parameter family of space curves each with nonzero torsion gives rise to a 1-parameter family of spherical curves, each of which has nonzero geodesic curvature and which contains the center of S in its convex hull. In [5] we have classified second order nondegenerate homotopy classes of curves on the unit 2-sphere; a second order nondegenerate curve on S being one such that the geodesic curvature is not zero. Two nondegenerate curves are nondegenerately homotopic if and only if they are regularly homotopic, their geodesic curvatures have the same sign and they are either both simple or both have double points. Nondegenerate simple curves must lie in a hemisphere (see Fenchel [3]), but among the classes of curves with double points it is possible to find nondegenerate curves which cross every great circle.

Design of Metformin HCl and Moxifloxacin HCl Loaded Thermosensitive In Situ Gel

: Corneal neovascularization (CNV) is a serious ocular surface disease that causes the cornea to lose its transparent structure. It is a difficult disease to treat, so different drugs and different carrier systems are tried in the treatment of the disease. One of these methods is the combined application of metformin HCl (MHL) with a fluoroquinolone group antibiotic. The aim of this study is to load MHL with low permeability into a drug delivery system that can prolong the residence time on the ocular surface. In this context, different in situ gel formulations were produced by using poloxamer, a thermosensitive polymer, together with hydroxypropylmethylcellulose, a natural viscosity increaser. In situ gels were evaluated for clarity, pH, gelation temperature, and rheological behaviors and selected two formulation. After loading MHL and moxifloxacin HCl (MOX) into these two formulations, it was determined that they were clear, had a pH of around 7, a gelling temperature of 34-35 °C, and showed pseudoplastic flow. However, drug loading capacities were found to be over 97%. When in vitro release studies were examined, it was determined that both MHL and MOX released for at least six hours. The results showed that the combination of PF127 and HPMC has potential as an in situ gelling systems for ocular delivery of MHL and MOX.
Fast Model Predictive Control System for Wave Energy Converters With Wave Tank Tests

At present, the mainstream solution for the control of wave energy converters (WECs), the model predictive control (MPC)-like method, faces a gap between simulation-based research and practical application. Two of the major difficulties are the online computation burden and the requirement of real-time wave information. In this study, a fast solving strategy is proposed at the level of quadratic programming (QP), where a tailored warm-start algorithm is designed and combined with an early stop technique. Simulations show that only one iteration of interior-point method (IPM) suffices to reach over 95% efficiency of the exact MPC, which significantly speeds up the computation. The fast strategy is then deployed on the real-time controller of a prototype WEC platform. During this implementation, the instantaneous wave force is estimated by a Kalman filter entirely based on the basic feedback signals: position, velocity, and the generator current, while future wave forces are predicted by an autoregressive model. The wave tank test confirms that the proposed fast MPC is capable of being executed at a high frequency, achieving stable operations within constraints, and reaching satisfactory energy efficiency under real wave-body interactions.
