The Effect of Mentoring on School Attendance and Academic Outcomes: A Randomized Evaluation of the Check & Connect Program

In response to budget problems, many urban school systems reduced resources for getting students to come to school, like truancy officers. Chicago, for instance, went from 150 truancy officers down to, in 1991, a total of zero. Is that a good idea? We explore here the effects of increased support by a pro-social adult, or “social capital,” delivered through a structured student monitoring and mentoring program called Check & Connect (C&C). We carried out a large-scale randomized controlled trial with C&C in partnership with the Chicago Public Schools (CPS) to students in grades 1-8. Program participation decreased absences in grades 5-7 by 4.2 days, or 22.9 percent, but with no detectable effects on students in grades 1-4. We also did not find statistically significant effects on learning outcomes such as test scores or GPA, or any detectable spillovers to other students within the schools where the program was administered. The modest impacts per dollar spent, compared to previous evidence on either low-cost "nudges" or relatively intensive, higher-cost interventions, raise the possibility that, for very disadvantaged students, there may be decreasing but then increasing returns to program intensity for the problem of student disengagement.
Bacterial and Fungal Contamination of Elevator Buttons in University Schools of Isfahan University of Medical Sciences, Isfahan, Iran

Background: The control of microorganisms in industrial and residential environments is the main concern regarding the spread of infectious diseases. Objectives: The current study aimed to isolate the bacteria and fungi from elevator buttons in the schools of Isfahan University of Medical Sciences, Isfahan, Iran. Methods: The study was a across sectional research. Samples were taken from elevator buttons in the schools of Isfahan University of Medical Sciences. Detection of the type of bacteria and fungi was done in blood agar, eosin methylene blue (EMB) agar and sabouraud dextrose agar according to the standard microbiological methods. Finally, Gram-positive and Gram-negative bacteria and fungi were identified. Results: This study was conducted on 35 buttons from seven elevators in Isfahan University of Medical Sciences schools. All the samples showed bacterial contamination (100%) with the kind of Gram-positive and -negative bacteria and all of them had Staphylococcus and Enterobacter species contamination. Schools of medicine, dentistry, management and medical information sciences had the highest bacterial contamination. On the other hand, fungal contamination was not detected in the samples. Conclusions: The study showed that elevator buttons could lead to transmission of pathogenic bacteria. It is necessary to clean and disinfect elevator buttons daily, especially in departments with high contamination potential such as laboratories, particularly in biological laboratories and pilot plant rooms.
Following doctors orders: understanding the phenomenon of gender-based harassment in acute care hospital's as experienced by female nurses.

Sexual and Gender Harassment are top of mind in the current cultural landscape, with marked increase in conversations and testimonials coming forward by women of diverse backgrounds, ages, careers and workplaces, both in the US and globally. The topic has created a vast channel of myriad communications and multi shaded responses to those women who have been courageous enough to open-up and share these oftentimes, shame filled and buried experiences. In organizations where there are more males in power over their female subordinates, as in healthcare, we see an increase in these types of gender/sex harassment/ behaviors. In phase one of this mixed method study a survey was used to collect occurrence, type and frequency of gender/sex harassment/abuse behaviors. In phase two, an interview process took place with the goal to better understand the lived experiences of female nurses who experienced some type of this behavior, and the impact and effects these experiences had on them psychologically, physically, and on their jobs. The conclusion was that acute hospitals have an organized patriarchy in place, male physicians are held in higher esteem and have more clout than female nurses. Male physicians use gender harassment language and behaviors to control, thereby maintaining their power within the organziation, whilst the implied authority of the MD is supported, even in the case of sexual assault. This renders a sick culture of sex/gender harassment/abuse where these types of behaviors occur with alarming frequency, leaving the emotional and psychobiological effects up to the nurse to deal with alone.
Effect of tannins and monensin on feeding behaviour, feed intake, digestive parameters and microbial efficiency of nellore cows

Abstract This study aimed to evaluate the associative effect of monensin and tannins on intake, feeding behaviour, digestibility, rumen kinetics, microbial protein synthesis and nitrogen balance. In a 2 × 4 factorial arrangement, 8 rumen cannulated Nellore cows were distributed in 2 contemporary 4 × 4 Latin squares and received 8 diets that differed in the level of tannins (0.00, 0.75, 1.50 and 2.25% DM) and presence of monensin. Monensin was daily administered to each cow in one square (about 32 mg/kg DM). No interaction between monensin and tannins was observed (p > .05). Tannins linearly reduced feed intake, but linearly increased daily eating time (p < .05), although these did not alter the number of meals. Monensin increased CP digestibility by 6% (p = .0387) while tannins linearly reduced digestibility of DM, CP, OM and TDN, whereas the reduction was quadratic for ADF and NDF. Tannins linearly reduced the rumen disappearance rate by linearly reducing both passage and digestion rates. Tannins also linearly reduced urinary urea, though neither additive affected microbial protein synthesis. Monensin reduced the proportion of N excreted in faeces, whereas tannins linearly increased faecal N and linearly reduced both urinary and retained N. Monensin and tannins have shown independent effects on feeding behaviour, feed intake, digestive parameters, microbial protein synthesis and N balance, but they did not improve nutrient usage, although monensin alone has shown to have potential to promote N utilisation. Tannins may play an important role in reducing the excretion of N in urine. Highlights Tannins reduce the efficiency of nutrient usage in cattle. Tannins change the pathway of the excretion of the feeding nitrogen. The emission of N2O from the urine may be reduced by the use of tannins in cattle feeding.
Mediating the victim–offender overlap with delinquent peer associations: a preliminary test of the person proximity hypothesis

ABSTRACT The principal goal of this study was to identify the mechanisms responsible for the victim-offender overlap. Participants were 1,354 (1,170 males, 184 females) youthful offenders (mean age = 16.04 years) from the Pathways to Desistance study. The path running from violent offending to violent victimization was tested for mediation using peer delinquency and unsupervised routine activities as mediators, whereas the path running from violent victimization to violent offending was tested for mediation using peer delinquency and depression as mediators. Congruent with the first research hypothesis, peer delinquency mediated the violent offending–violent victimization pathway and did so significantly better than unsupervised routine activities. Contrary to the second hypothesis, peer delinquency did not mediate the violent victimization–violent offending pathway. The role of person proximity and peer selection in linking violent offending to future violent victimization is discussed.
Acoustic Scattering in Sheared Flow

Airframe noise, the noise of an aircraft in flight not due to the engine or other mechanical devices, is often a major contribution to the sound heard from an aircraft during landing approach. Over the past few decades certification requirements have gradually tightened, reaching the point where the required noise reductions cannot be achieved through reducing engine noise alone. There are, similarly, restrictions on the noise output of wind turbines to reduce their impacts on local communities and wildlife. In practice this is achieved by braking the turbines at high speed, reducing energy outputs and efficiency. For both aircraft wings and turbine blades, the sharp trailing-edge is a well-understood and unavoidable source of noise, scattering vortical, hydrodynamic disturbances within the boundary-layer into far-field, acoustic, noise. Inspired by nature, for example the silent flight of owls, modification of the flow within the boundary-layer near the trailing-edge, either through passive or active devices, appears to offer methods of reducing far-field noise. The precise mechanisms are not completely understood, and this work focuses on the effect of varying boundary-layer parameters near the trailing-edge on the resulting far-field noise. Alternative methods of noise reduction include the addition of linings, for example via arrays of Helmholtz resonators. The junctions at the leadingand trailing-edges of such linings can again be a source of far-field noise, through a similar mechanism to that of a trailing-edge. This scattering is analysed within a simplified mathematical framework through an application of Rapid Distortion Theory, considering linearised perturbations to a transversely sheared background flow. Within this framework, the development of disturbances within a boundary-layer are investigated, both hydrodynamic and acoustic, over a variety of mixed boundary conditions. The inclusion of background shear requires numerical solution of differential equations, which are paired with complex variable techniques such as the Wiener-Hopf method, constructed for the solution of boundary-value problems with discontinuous boundary conditions. The possibility of exact solutions using this technique allows asymptotic methods to be used to directly evaluate far-field noise.
Effect of proficiency on subject-verb agreement processing in French learners of English: An ERP study

This study explored the effect of proficiency on the native-likeness of syntactic processing in a second language. ERP responses to violations of third-person singular subject-verb agreement were obtained from advanced and intermediate adult French learners of English as well as English native speakers. Our findings show a proficiency effect only in early ERP responses to violations, and suggest that the highest level of proficiency attainable through instruction in France is not enough to exhibit entirely native-like responses
Teachers’ Stories on Sense of Belonging in Co-Teaching Relationship

ABSTRACT The aim of this article was to examine primary school teachers’ perceptions about their sense of belonging in co-teaching. We were particularly interested in investigating the factors which enhance or hinder teachers’ sense of belonging in their co-teaching relationships. The data were collected using the method of empathy-based stories (MEBS) consisting of frame stories with a variation in whether a co-teaching situation was experienced as positive or negative. Qualitative analysis of the stories revealed that teachers’ sense of belonging was constructed through three dimensions: (1) teachers’ work practices, (2) mutual relationship, and (3) individual characteristics. The findings contribute to the literature by demonstrating that a sense of belonging in co-teaching is a multidimensional phenomenon that is built in a close collegial relationship between teachers. The study adds a new micro-level perspective on how teachers’ sense of belonging is constructed between two co-teachers.

Gut Microbiota Imbalance is Related to Sporadic Colorectal Neoplasms. A Pilot Study

(1) Background: Colorectal cancer (CRC) development is sustained by multiple factors including the gut microbiota, as suggested by a growing body of evidence. Most CRCs have a sporadic (non-hereditary) onset and develop from sporadic colorectal adenomas/polyp (SCA/P). In the present study, we investigated the characteristic of anaerobic microorganisms in stool samples obtained from 20 patients with SCA/P and 20 subjects without evidence of proliferative lesions at colonoscopy (Controls). (2) Material and Methods: We designed this clinical trial using adaptive randomization by minimization. Selective culture media and Matrix Assisted Laser Desorption Ionization Time of Flight (MALDI-TOF) mass spectrometry techniques were used to identify the components of microbiota. The data obtained revealed a different variability of gut microbiota in stool samples of controls and SCA/P subjects. (3) Results: The most interesting difference was observed for Bacteroides species, which represent the 50% of all bacterial species identified in the stool samples: two species, Bacteroides stercoris and Parabacteroides distasonis, were found only in the feces from control group, whereas Bacteroides fragilis and Prevotella melaningenica species were presents only in SCA/P patients. Among Gram+ bacteria also, specific species were found in the two groups of feces: Clostridium clostridioforme, Propionibacterium avidum and Pediococcus pentasaceus were identified only in controls, while Eubacterium limosum, Clostridium innocuum and Corybebacterium xerosus were identified in SCA/P stool samples only. (4) Conclusions: Our findings suggest that, compared to control stool samples, a different intestinal microbiota is present in SCA/P stool samples, that may create a micro-environment predisposing for the development of proliferative phenomena. As a consequence, gut microbiota manipulation could be a future target for personalized treatments.
Machine Learning-Based Financial Statement Analysis

This paper explores the application of machine learning methods to financial statement analysis. We compare a range of models in the machine learning repertoire in their ability to predict the sign and magnitude of abnormal stock returns around earnings announcements based on past financial statement data alone. Random Forests produce the most accurate forecasts and the highest abnormal returns. (Nonlinear) neural network-based models perform relatively better for predictions of extreme market reactions, while the linear methods are relatively better in predicting moderate market reactions. Long-short portfolios based on model predictions generate sizable abnormal returns, which seem to decay over time. Abnormal returns are robust to various risk factors and load in expected ways on size, value and accruals. Analysing the underlying economic drivers of the performance of the Random Forests, we find that the models select as most important predictors financial variables required to forecast free cash flows and firm characteristics that are known cross-sectional predictors of stock returns.
Self - Employment Among Youths in Ojo and Alimosho LGA, Lagos Nigeria: Perceptions, Attitude and Contributions – A Statistical Assessment

This study examined the perceptions, attitude and contribution of self – employment among youths in Lagos State with the aim of ascertaining the factors that inspire perception, attitude of youth self-employment and how it impacts the youths. A survey was conducted among youths in Ojo LGA, Lagos State Nigeria using a self - designed questionnaire collect data on different factors related to youth perception, attitude and contributions to self-employment. Data collected was analysed using descriptive statistic, Chi Square test and Analysis of Variance with the aid of Statistical Packages for Social Science (SPSS). The result show that 57.0% of the youths agreed that self-employment development among young people is high and this was significantly associated with perception and attitude of self-employed youth (p < 0.05). However, the perception, attitudes and views on contribution of self – employment differed significantly among youths from the major ethnic nationalities in Nigeria (p < 0.05). It was therefore concluded that some demographic factors are significantly associated with perception and attitude of youths on self-employment. Also, self – employment improves the standard of living of youths and increase national income while lack of conducive business environment, high cost of doing business and lack of strong and consistent patent – law was among the factors that significantly negatively impact self – employment drive in the country. The study recommended that the government should create a conducive business environment and work towards reduction of the high cost of doing business as a way of encouraging youths into self - employment. Keywords : Self – employment, perception, contribution, standard of living, youths DOI : 10.7176/JPID/51-05 Publication date: November 30 th 2019
Institutional ownership and workplace misconduct: Evidence from federal labor law violations

We examine the effect of institutional investors on labor-related misconduct. We find that institutional ownership is negatively associated with firms’ propensity to violate federal labor laws. Additional tests using instrumental variables and regression discontinuity suggest a causal relation. Our evidence suggests that institutional investors’ aversion to poor labor practices is mainly motivated by financial rather than social reasons. Although the direct penalty amounts are small, violating firms face a higher likelihood of employee lawsuits in subsequent years and experience reputational loss and negative stock returns. Lastly, our findings suggest that institutional investors mitigate poor labor practices via shareholder monitoring and voice.
THE EFFECT OF COMPETENCE AND MOTIVATION ON ORGANIZATIONAL COMMITMENTS AND ITS IMPLICATIONS ON EMPLOYEE PERFORMANCE

The purpose of this study is to find out and explain the effect of competence and motivation on organizational commitment and its implications for employee performance, which in this case is the performance of the PBC Audit Functional Officer at the Directorate General of Customs and Excise, Ministry of Finance of the Republic of Indonesia. The research method uses a quantitative approach, which became the population in this study were 318 PBC Audit Functional Officers of the Directorate General of Customs and Excise. The selection of sample is done by simple random sampling technique (Slovin 10% error tolerance), so that 77 respondents are determined. Data collection techniques that used are interviews and questionnaire instruments. The questionnaire survey instrument was randomly delivered to the PBC Audit Functional Officer at the Directorate General of Customs and Excise. The data is analyzed using structural equation modeling (SEM) with the Smart PLS 3.0 software program. This study revealed that competence, motivation and commitment organizational had a significant positive effect on employee performance, both partially and simultaneously. Besides that, organizational commitment variable does not mediate competence and motivation variables on employee performance.

A trajectory of a mediational means in protest: the hand placard in South Korea’s Candlelight Protests

ABSTRACT While positioning this research within the growing body of scholarship related to linguistic landscape of protest, we illustrate a distinctive form of analysis. Rather than giving a generalized, extensive, or quantitative description, we focus on a qualitative and in-depth analysis of a single protest tool in relation to protest actions and space-making. Drawing on the concept of “mediational means” from mediated discourse analysis, we analyze the linguistic and semiotic functions and effects of sonp’aenmal (hand placard), a protest tool uniformly and widely employed during South Korea’s 2016–2017 Candlelight Protests. Based on a corpus of protest images and our autoethnographic accounts of direct participation, we examine why this sign emerged as an important tool in the protest space, how it was utilized ritually and creatively, and the effects of its use on protesters’ experiences, sensitivity, and identity. Competing discursive effects caused by its uniform design and widespread use are discussed further.
Security and Feasibility of Laparoscopic Rectal Cancer Resection in Morbidly Obese Patients

Background: Rectal resection for cancer can be technically challenging, especially in the obese patient. While some have investigated the impact of laparoscopic surgery on rectal cancer, no study looked at the subgroup of morbidly obese patients. Objectives: Our goal was to evaluate feasibility and safety of laparoscopic rectal resection for cancer in this population. Methods: All morbidly obese patients, defined as a body mass index (BMI) of 40 kg/m or greater, undergoing laparoscopic rectal cancer resection for primary cancer between January 2006 and July 2013, were identified using medical records in a single academic hospital center. Results: Thirteen patients underwent laparoscopic approach. The median BMI was 42.4 kg/m. There were 4 conversions (30%). Anastomotic leak occurred in 2 patients (15.4%). TME was complete in only 9 patients (69.2%), with 3 patients with incomplete TME being also in the conversion group. There was no mortality. There was no recurrence. Conclusions: This study suggests that laparoscopic rectal resection for cancer in morbidly obese patients is challenging and associated with a higher rate of conversion compared to patients with lower BMI. Mortality, morbidity and readmission rates are similar to the literature showing the same benefit for laparoscopic procedure.
