Immigration and Violent Crime: Evidence from the Colombia-Venezuela Border

This paper investigates the link between violent crime and immigration using data from Colombian municipalities during the recent episode of immigration from Venezuela. The key finding is that, following the closing and then re-opening of the border in 2016, which precipitated a massive immigration wave, homicides in Colombia increased in areas close to the border with Venezuela. Using information on the nationality of the victim, we find that this increase was driven by homicides involving Venezuelan victims, with no evidence of a statistically significant increase in homicides in which Colombians were victimized. Thus, in contrast to xenophobic fears that migrants might victimize natives, it was migrants, rather than natives, who faced risks associated with immigration. Using arrests data, there is no corresponding increase in arrests for homicides in these areas. Taken together, these results suggest that the increase in homicides close to the border documented here are driven by crimes against migrants and have occurred without a corresponding increase in arrests, suggesting that some of these crimes have gone unsolved.
PENGARUH NET PROFIT MARGIN, GROWTH, CASH POSITION TERHADAP KEBIJAKAN PEMBAYARAN DIVIDEN

Penelitian ini bertujuan untuk mengetahui serta menguji pengaruh net profit margin, growth yang diukur dengan proksi asset growth, cash position terhadap dividend payout ratio, sebagai dasar perusahaan dalam membayarkan dividen kepada pihak investor. Sumber data yang digunakan merupakan data sekunder. Populasi dalam penelitian ini perusahaan perbankan yang terdaftar di Bursa Efek Indonesia periode 2011-2018. Teknik pengambilan sampel menggunakan metode purposive sampling, dengan total sampel yang didapat berjumlah 64 sampel. Metode analisis data yang digunakan adalah analisis regresi linier berganda. Hasil penelitian ini menunjukkan variabel net profit margin berpengaruh signifikan terhadap dividend payout ratio yang berarti, semakin besar net profit margin akan menurunkan dividend payout ratio yang akan dibayarkan oleh perusahaan. sementara asset growth tidak berpengaruh signifikan terhadap dividend payout ratio artinya, besar atau kecilnya nilai pertumbuhan aset tidak mempengaruhi besar atau kecilnya pembayaran dividen yang dibayarkan oleh perusahaan, dan cash position juga tidak berpengaruh signifikan terhadap dividend payout ratio yang berarti, apabila perusahaan mempunyai kondisi likuiditas atau posisi kas buruk, perusahaan biasanya membagikan dividennya dengan jumlah kecil
Molecular dynamics simulations of amphiphilic dendrimers

We study the static and dynamic properties of amphiphilic dendrimers of generation 3 through 7 in an explicitly modeled solvent with molecular dynamics. All interior monomers are solvophobic while the terminal monomers are varied from all solvophobic to all solvophilic, with a number of non-uniform solvophobic / solvophilic terminal monomer arrangements investigated. For generations 6 and 7, crowding at the dendrimer surface forces some solvophilic monomers into the interior of the molecule. The non-uniformly surface-modified dendrimers are studied to examine how different arrangements of terminal monomers might affect dendrimer conformation. In all cases with solvophilic terminal monomers we find the solvophilic monomers congregating at the surface; thus, the dendrimer adopts the form of a unimolecular micelle. For generation 5 and smaller, the terminal monomer arrangement has no effect on the static or dynamic properties. For generations 6 and 7, a minimum number of bonds between the two types of terminal monomers is required to observe all solvophilic terminal monomers at the surface of the molecule. Lowering the simulation temperature, which effectively increases the interaction strength between solvophilic monomers and solvent, eliminates the back folding Reproduced with permission from Macromolecules 39 (2006) 4247-4255.

Assessing the Role of Soil Chemoautotrophs in Carbon Cycling: An Investigation into Isotopically Labelled Soil Microorganisms

Recently observed increases in atmospheric CO2 have created great interest in carbon capture technologies and natural sinks of this major component of the carbon cycle. Humic substances are a large, operationally defined fraction of soil organic matter. It was thought that humic substances consist of cross-linked macromolecular structures forming a distinct class of compounds. However, it was recently concluded by members of my research group that the vast majority of humic material in soils, are a complex mixture of microbial/plant biopolymers and degradation products, and not a distinct chemical category. The postulation that microbial inputs to soil carbon are greatly underestimated was put forward by my research group in 2007. Therefore, I have attempted to demonstrate the inputs made by soil chemoautotrophic bacteria. A method was developed where soil samples were measured for chemoautotrophic activity by subjecting them to a suite of scientific techniques. A growth chamber was used to propagate extant soil chemoautotrophic bacteria from different soils and subjected to an array of chemical and biological analyses. The growth chamber was used to measure CO2 concentrations and introduce stable isotopic 13CO2. Estimations of CO2 sequestration were made using direct measurements for Irish soils and one Eurasian soil. Isotope labelled DNA was isolated using cesium chloride gradient ultracentrifugation. The dominant chemoautotrophic bacteria uncovered were Thiobacillus denitrificans and Thiobacillus thioparus. Labelled biomass was isolated and described using GCMS-IRMS and NMR, where an array of PLFAs, protein/peptide, carbohydrates and aliphatics were observed. Finally, an attempt to mimic common agricultural practice was performed to measure soil chemoautotrophic activity. This demonstrated the capability of this approach to benefit carbon flux estimations and hopefully in the future help to elucidate carbon flow into soils for the greater environment.
Effects of acute stress on emotion recognition in the menstrual cycle

The early follicular menstrual cycle phase is associated with enhanced female emotion recognition performance compared to the midluteal phase, likely due to differing estradiol and progesterone levels. Acute stress appears to also influence emotion recognition in females, but the direction of the effect is inconclusive. To fill in the gap in the literature, the present study examined the effects of acute stress on emotion recognition in specific phases of the menstrual cycle. Nineteen female psychology students between the ages of 18-29 years with regular menstrual cycles (i.e. 26-31 days in length) were recruited from the University of Regina via the Psychology Participant Pool. Participants performed a high or low stress task in the early follicular phase (low estradiol and progesterone levels) or midluteal phase (high estradiol and progesterone levels) before completing facial and auditory emotion recognition tasks. Results for auditory emotion recognition accuracy show the high stress condition outperformed the low stress condition for those in the early follicular phase group, but the opposite occurred in the midluteal phase group. Similar trends emerged for auditory emotion recognition reaction time and facial emotion recognition accuracy and reaction time. The present study suggests an interaction between sex hormones and the HPA axis on emotion recognition, but it is limited by its small sample size and estimation of sex hormone levels based on menstrual phase. Future studies could consider recruiting male participants, investigating oral contraceptive use, and administrating hormones to further examine the interaction between sex hormone levels and stress on emotion recognition performance.
Quantum dynamics studies of the photodissociation of molecular systems

The focus of the work presented here is the theoretical description of the photodissociation of molecular systems possessing low-lying singlet 3s/\(\pi\)σ* states that are quasi-bound with respect to an N-H bond. Model Hamiltonians are developed for and subsequently used in quantum dynamics simulations of the photo-induced dynamics of the molecules ammonia, 3-pyrroline, pyrrole, and aniline. The origin to the barrier to dissociation in ammonia's first excited state is identified and the effect of vibronic coupling of this state to a number of higher-lying states on the dissociation dynamics of the molecule is assessed. A conformer-resolved study of the dynamics of 3-pyrroline following excitation into its first two excited states is performed, and the first two bands in its electronic spectrum are calculated and analysed. The first band in the electronic spectrum of pyrrole is calculated, its vibrational structure assigned and the role played by intensity borrowing in its formation analysed. The dynamics of aniline following excitation to its first to singlet \(\pi\)\(\pi\)* are studied. Two previously neglected 3p Rydberg states are found to play important roles in aniline's excited state dynamics. The first two bands in aniline's electronic absorption spectrum are calculated, and the role played by the Hertzberg-Teller effect in the first band is analysed
Effect of change from a determinate to a semi-determinate growth habit on the yield and lodging resistance of soybeans in the northeast region of Japan

Although an indeterminate growth habit is attractive to develop high-yield soybean varieties with higher number of pods (Glycine max (L). Merr. ), lodging in indeterminate varieties remains a problem in Japan. As the semi-determinate varieties have shorter main stem length than the indeterminate varieties, this trait can be useful to improve varieties with high yield and low lodging risk. We introduced the genes Dt1 and Dt2, which regulate stem growth habit, into three determinate varieties by backcrossing and evaluated the resulting effects on yield and lodging tendency under four different growing environments. The yield and lodging degree of the semi-determinate and indeterminate lines were higher and more severe than those of the determinate lines. Despite the lower overall lodging score, the semi-determinate lines had marginally lower overall yield than that of the indeterminate lines. However, the effect of introduction of semi-determinate traits on yield and lodging degree was different in the three backgrounds, with the yield of semi-determinate lines being the highest and the difference in lodging degree between the semi-determinate and determinate lines being under 1.0 in one background. Therefore, semi-determinate growth habit has potential to develop high yielding varieties with low lodging risk.

Amultiple-case study analysis of a widespread tool for sustainable supply chain management

This article analyses one of the most common tools employed by global focal companies in sustainable supply chain management (SSCM) across all industries: supplier sustainability self-assessment questionnaires. Extant research has moved beyond the questions of whether and which suppliers should be assessed. Current research is already focussing on how to share and standardise such assessment data. Despite mounting general research on SSCM, we identified that specific tools such as self-assessment questionnaires have not been empirically analysed in SSCM literature. Thus, this paper addresses the research questions of what differences there are among supplier self-assessment questionnaires and how supplier responses to such questionnaires might be influenced. Our research involves an abductive multiple-case study design and an analysis of over 25,000 responses from globally dispersed suppliers to two types of supplier sustainability self-assessment questionnaires administered and requested by a global automotive focal company. Although the two questionnaires covered similar areas of sustainability practices and were administered to suppliers of the same focal company, the suppliers’ responses demonstrated various observable differences in average sustainability scores. Social desirability bias and supplier assessment fatigue were identified as issues confronting such questionnaires. We find that questionnaire design, how the questionnaire is embedded in the focal company’s processes and institutional settings are factors that potentially influence suppliers’ responses and could counteract social desirability bias and supplier assessment fatigue. Based on these findings we make suggestions for improving these SSCM tools and provide recommendations for further research.

Background. Childhood abuse is a risk factor for poorer illness course in bipolar disorder, but the reasons why are unclear. Trait-like features such as affective instability and impulsivity could be part of the explanation. We aimed to examine whether childhood abuse was associated with clinical features of bipolar disorder, and whether associations were mediated by affective instability or impulsivity. Methods. We analysed data from 923 people with bipolar I disorder recruited by the Bipolar Disorder Research Network. Adjusted associations between childhood abuse, affective instability and impulsivity and eight clinical variables were analysed. A path analysis examined the direct and indirect links between childhood abuse and clinical features with affective instability and impulsivity as mediators. Results. Affective instability significantly mediated the association between childhood abuse and earlier age of onset [effect estimate (θ)/standard error (SE): 2.49], number of depressive (θ/SE: 2.08) and manic episodes/illness year (θ/SE: 1.32), anxiety disorders (θ/SE: 1.98) and rapid cycling (θ/SE: 2.25). Impulsivity significantly mediated the association between childhood abuse and manic episodes/illness year (θ/SE: 1.79), anxiety disorders (θ/SE: 1.59), rapid cycling (θ/SE: 1.809), suicidal behaviour (θ/SE: 2.12) and substance misuse (θ/SE: 3.09). Measures of path analysis fit indicated an excellent fit to the data. Conclusions. Affective instability and impulsivity are likely part of the mechanism of why childhood abuse increases risk of poorer clinical course in bipolar disorder, with each showing some selectivity in pathways. They are potential novel targets for intervention to improve outcome in bipolar disorder.
The Dynamic Relationship between Ownership Structure and Corporate Performance: Evidence from the Vietnamese Food Industry

: Purpose: Our analysis provides empirical evidence on the dynamic relationship between ownership structure and corporate performance in the context of Vietnam. Approach/Methodology/Design: Our findings are drawn from the comprehensive data set of stocks listed on both the Hochiminh Stock Exchange and Hanoi Stock Exchange in the food industry from 2007 to 2018. Findings: The results indicate that both managerial shareholdings and ownership concentration negatively drive corporate performance. We further find that corporate performance is also a positive function of both managerial shareholdings and ownership concentration. Practical Implications: The results support the entrenchment hypothesis that the divergence of ownership and control helps managers accumulate substantial private benefits without actually bearing the costs. Block-holders also accumulate private benefits of control through pyramid business structures and cross-holdings across different firms. Therefore, both block-holders and managers are motivated to indulge in non-value maximizing behavior, deteriorating corporate performance. Originality: The entrenchment hypothesis does only exist at a low level of ownership. At the high level of ownership, the entrenchment hypothesis is positioned by the incentive hypothesis. Accordingly, their self-interest behaviors are more likely to be detected and legally riskier. They are motivated to indulge in value-maximizing behaviors and synchronize the interests of shareholders and managers. However, our findings are in line with Cui and Mak and who reveal the nonlinear relationship between managerial ownership and firm performance with a U-shaped curve for high R & D firms in the USA and Australia. Our empirical evidence conflicts with Hoang al.
Biochemical Effects of Hydroclathrus clathratus on Alloxan Induced Diabetic Rats

Alloxan administration in male albino rats, induced diabetes by increasing blood glucose concentration and reducing hepatic glycogen content as compared to normal control group. Besides, serum lipid profile parameters such as total-cholesterol, triglyceride, low-density lipoprotein and very low-density lipoproteincholesterol were also elevated, whereas, the level of high-density lipoprotein-cholesterol was reduced significantly (P<0.05) in diabetic rats. Treatment of diabetic animals with hot aqueous extract of Hydroclathrus clathratus for 30 days, significantly lowered blood glucose level, elevated hepatic glycogen content and maintained body weight and lipid-profile parameters near normal range. Declined activity of antioxidant enzymes and concentration of non-enzymatic antioxidants were also normalized by (HCE) extract of Hydroclathrus clathratus treatment, thereby reducing the oxidative damage in the tissues of diabetic animals and hence indicating the antidiabetic and antioxidant efficacy of the extract. Biochemical observations were further substantiated with histological examination of pancreas and liver.
Stock Market Vulnerability to the COVID-19 Pandemic: Evidence from Emerging Asian Stock Market

This paper studies empirically the emerging Asian stock market vulnerability to pandemics. Taking the Covid-19 virus as a case study, we used the ARDL panel data approach to investigate the impact of the daily Covid-19 confirmed cases along with a behavioral component based on a triggering fear event related to news about Covid-19 deaths. The results indicate that both the reported daily growth of Covid-19 confirmed cases along with the triggering fear event related to news about death, affected the Asian stock markets performance negatively, other variables such as oil price, gold price, exchange rates, and the US stock market were also found to be determinants of the Asian stock markets during the studied period.
Assessment on Livestock Production: Opportunities and Challenges to Livestock Household in Welkayt District

Livestock production is contributing a great role in the livelihood of the rural community although is being challenged by various constraints. A questionnaire based cross sectional study was conducted on 183 individuals (96 farmers, 73 factory workers, 10 peasant association and 4 veterinarians) from November 2014 to April 2015 to assess the existing opportunities and challenges on livestock production in Welkayt district. Individuals were interviewed to obtain information related to marketing information, animal health service and breed status, feed availability and management system on livestock production. Accordingly, the presence of Welkayt Sugar Project, availability of productive breeds (Begait), and proximity to Sudan and Eretria borders for the international market are some of the identified opportunities for livestock development in the district. However, out of the 96 farmer participants indicated insufficient animal feed in the quantity and quality (45.8%), poor technology supply (43.8%) and poor veterinary service provision (41.7%) as the major challenges in the district. Similarly, veterinarian expertise respondents replied as there were insufficient drugs and equipment’s supply in the existing clinic in the district. During the interview all the respondents reflected that there is declining of grazing pasture from time to time. As a result, the animal owners used animal feeds originated from factories and concerning the perception of the respondents since they have a lack of knowledge on the health and feed management of animals’ continuous awareness creation and improvement of the existing breeds using artificial insemination (AI) should put in place.
