The Impacts of Social Proximity : On the Effects of in-house Ownership and Family Ties on Firm Performance

In recent studies, scholars have shown that geographical proximity alone is not sufficient to trigger collaboration and knowledge spillovers but knowledge networks enhanced by mutual trust. A handful of studies in this direction have assessed the impacts of family ties on firm performance. While families may enhance the possibility of finding a job, little is known about how in-house ownership and family ties facilitate interactive learning and performance. By means of longitudinal data (2002-2012) on a sample of private owned firms with up to 50 employees with matched information on all the employees, we are able to map all in-house ownership and family ties. Our fixed effects estimates reveal that the existence of family ties in the firm changes previously reported positive effects of related variety in formal education ‒ higher levels of related variety decrease performance in firms where there are family ties. This is especially the case when family ties involve owner/child relationships.
Yield and Yield Components of Some Sugar Cane Varieties (Saccharum officinarum L.) as affected by Different Nitrogen Fertilization Levels

Two field trials were conducted during two successive growing seasons of 2016/2017 and 2017/2018 at Mallawy Agricultural Research Station, Agricultural Research Center, El-Minia Governorate (Middle Egypt) to study the effect of different levels of Nfertilization (160,190 and 220 kg /fed) on yield, yield components and quality of five sugar cane varieties (G.T.54-9(C9), G.2003-47, G.99-103, G.2004-27 and G.2010-7). A split plot design with three replications was used, main plots were represented by five sugar cane varieties (V1= G.T.54-9(C9), V2= G.2003-47, V3= G.99-103, V4= G.2004-27, V5= G.2010-7). The subplots were used for the three nitrogen levels (160, 190 and220 kg N / fed). The results indicated that: 1Sugar cane varieties and N-fertilization levels exhibit significant effect on all studied traits in both seasons. Promising variety G.99-103 recorded the highest values of stalk hieght, stalk diameter (cm), millable cane ton/fed and sugar yield (ton/fed) in both seasons, while G.T. 54-9(C9) variety recorded the highest values of sucrose %, purity% and sugar recovery%, whoever G.2004-27 variety outyielded the highest value of TSS%2Increasing applied N levels from 160 up to 220 Kg N/fed significantly increased stalk height, stalk diameter(cm), millable cane ton / fed, sugar yield (ton/fed) and TSS (%), while190 Kg N/fed had the highest values of purity% and Sugar recovery%. 3The effect of interaction between sugar cane varieties and nitrogen levels on the studied traits was significant for stalk height in both seasons and purity%, sucrose % and T.S. S. % in plant crop season only. Generally, it could be concluded that under Middle Egypt conditions, it is recommended to inoculate G.99103 sugar cane varieties with 220 Kg N/fed to maximize the productivity and quality of sugar cane yield.
Endocrine-Related Cancer ( 2002 ) 9 15 – 32 Progress in breast cancer chemoprevention

Over the past years there have been significant advances in breast cancer treatment and early detection. For the first time, a decrease in cancer mortality has been observed. Recently, much progress has been made in the understanding of carcinogenesis partly due to available new technologies to detect early molecular changes in the tissue. The knowledge of breast cancer carcinogenesis has provided possible opportunities to prevent breast cancer. Currently, several clinical breast cancer prevention trials are ongoing. This paper reviews issues related to breast cancer chemoprevention including identification of high risk cohorts, endpoint biomarkers, current and new chemopreventive agents as well as models to evaluate these agents.

Toxic effect of Bacillus thuringiensis (Serotype 14) bacteria shows behavioural & histological changes on mosquito larvae

In this current situations the bacteria, Bacillus thuringiensis is a gram positive, rod shaped and aerobic soil bacteria. Bt is a bacterium that is not toxic to humans or other mammals but is toxic to certain insects when ingested. Bt works as an insecticide by producing a crystal-shaped protein (Cry toxin) that specifically kills certain insects. These bacteria produces a proteinaceous parasporal crystal in the sporangium at the time of sporulation. These proteins possess insecticidal properties and are called Bttoxins or delta endotoxins and also called as insecticidal crystal proteins (ICPs). It is not a single toxin but a class of toxic proteins produced from protoxin that are degraded by proteolytic enzyme to form smaller toxic peptides. In this study the mosquito larva are considered as predators which feed on some protozoan’s and bacteria, the fixation of concentration levels to larva was 9 gm of (Serotype 14) Bt induced to 10 liter of water which contains 100 mosquito larvae. When these larvae feed on Bacteria, Bacillus thuringiensis it show behavioral changes like erratic swimming, slow motility and larva move towards the surface of water and regurgitation because of Bt-crystals effects on enzyme present in the larvae i.e. Cytochrome-c-Oxidases due to oxidative stress and the liberated crystal toxin like Cry-II and Cry-IV bind into the larva gut cell membrane it shows the slight histological changes also and it paralyzes the digestive tract and forming a pore in that regions and results in the death of the larva. This show the toxins nature of Bacillus thuringiensis bacteria against the mosquito larvae.
Distribution of bivalve larvae at a frontal system in the James River , Virginia *

The James River is the southernmost of the major subestuaries of the Chesapeake Bay, USA. A frontal system develops on the early flood tide in the Hampton Roads region of the lower James. This system, together with a cyclonic gyre in Hampton Roads, is in part responsible for partial retention of downstream-flowing water in the estuary and it's injection into deeper, upstream-flowing water. The role of the frontal system in retention of bivalve larvae in the James was investigated In a 2-part study: a field exammation of larval distr~bution versus depth along a transect across the front in relation to salinity and temperature of the converging and diverging water masses, and a laboratory examination of the ability of oyster Crassostrea virginica larvae to swim in and through salinity gradients comparable to or greater than those encountered near the frontal system. Field studies indicate that larvae are passively transported through the frontal system and plunge to depth as the more saline water in which they are entrained encounters less saline water The deeper, more saline water flows upstream as it leaves the frontal system. Laboratory studies demonstrate that both straight hinge stage (mean length = 7 5 ~ ) and umbo stage (mean length = 157.5 to 159.7 pm) larvae actively swim through a salinity discontinuity of 3 %D when exposed in a column of 22 960 water overlayed by 19 9b. water (extreme values charactenstic of bottom and surface water at the frontal system). Further, their mean rates of vertical movement (0.37 to 1.02 mms-') illustrate the ability of larvae to move through the depth of the water column in the James in less than one tidal cycle. Pediveliger stage oyster larvae (mean length 317.2 pm), by contrast, restricted swimming to small but frequent excursions above the bottom in the laboratory apparatus and did not swim through the salinity interface. Following passive transport through the frontal system in the lower James straight hinge and umbo stage larvae may employ active depth regulation to redistribute throughout the water column; however, pediveliger stage larvae probably remain near the sediment-water interface.
Documentos de Trabajo Impact of a Work-Study Programme for Teenagers : Evidence from a Randomized Controlled Trial

We present an impact evaluation of a labour programme oriented to young students called “Yo Estudio y Trabajo” (“I Study and Work”) carried out in Uruguay. It is one of the first such evaluations for this country. We estimate the programme’s effects on the probability of being formally employed and continuing to study. Impacts on the very short term (about three months after the programme ended), on the short term (15 months after programme finalisation) and on the medium term (27 months after the programme was completed) are analysed. We use administrative records provided by the public social security provider, the public education administration and the state university. We were able to match all candidates for selection into the programme (over 46,000) with their administrative records. Exploiting the programme’s random selection process, we apply experimental techniques to evaluate its effects through univariate models. In addition, we allow for interdependence between the decisions of working and studying through a bivariate probit model. Results indicate different effects depending on the characteristics of the individuals and the time span considered. In particular, for socially vulnerable youths we find that the programme increases their probability of being formally employed between 8 and 12 percentage points (depending on the particular model considered) in the medium term. These results are robust to different specifications and provide evidence in favour of increasing the programme’s coverage of socially vulnerable youth (a policy that has been under way since 2015).
Effect of Extraction Solvents on Phenolics and Antioxidant Activity of Selected Varieties of Pakistani Rice ( Oryza sativa )

This paper reports the effect of different extraction solvents (aqueous & pure methanol, aqueous & pure ethanol & aqueous & pure isopropanol) on the effective recovery of phenolics and antioxidant activity of 10 varieties of rice) using orbital shaker technique. The extraction yields of antioxidant components from the tested varieties of brown (unpolished) rice ranged from 1.56 g/100 g in Basmati 2000 to 3.45 g/100 g in Basmati 370. The contents of total phenolics (TP) were determined to be highest (293.2 mg GAE/kg) in Basmati Pak while lowest (130.2 mg GAE/kg) in Irri 6 rice. The antioxidant activity, following the determinations of 2,2-diphenyl-1-picrylhdrazyl (DPPH) free radical-scavenging capacity, reducing power and ferrous ionchelating activity, revealed that Basmati Pak, Basmati 2000 and Basmati 515 rice varieties have greater antioxidant potential. Overall, aqueous isopropanol (80:20 isopropanol: water v/v) and aqueous methanol (80:20 methanol: water v/v) were noted to be the most effective solvent systems offering higher extraction yields, TP and antioxidant activity for the tested rice varieties. This study advocates the use of appropriate extraction solvents to recover maximum amount of rice antioxidants. It was concluded that the tested varieties, especially the Basmati cultivars, of Pakistani rice are a potential source of valuable antioxidant components and thus could be explored as ingredients for functional foods and nutraceuticals. © 2012 Friends Science Publishers
Early Memories of Positive Emotions and its Relationships to Attachment Styles , Self-Compassion and Psycopathology in Adolescence

Literoture has shown thot early childhood experiences, especiolly those related to feelings of wormth or safeness play o key role in emotional cmd social subsequent development. These early experiences of safeness and sooth ng may lead to the ability for self-reassurance and self-soothing, especially in face of setbacks or failures (Gilbert, 2005; Ritcher, Gilbert, & McEwan, 2009). Research has shown that self-compassion is associated with psychological well-being and lower levels of depression and anxiety (Neff, 2003; Neff, Kirkpatrick, & Rude, 2007). Given the developmental tasks in adolescence, it may be beneficial to help adolescents develop selfcompassion skills (Neff & McGehee, 201 0).
Institutional experience on the prevalence of the Odontogenic tumors: A retrospective analysis

Background and Aim: Most of the available literature is from Africans and American countries, which showed that difference of frequency in the distribution of the different type of Odontogenic tumors. However there is very little information about the prevalence of Odontogenic tumors in India. Hence the present study was carried out to provide data on Odontogenic tumors and to provide the frequency distribution of the same in different medical institutes in Indore city Materials & Methods: Medical institute in Indore city were reviewed for the retrieval of the data for the study. For the inclusion in the study, the histopathological reports were retrieved from the pathological department of the respective institute. All the lesions which were diagnosed as Odontogenic lesions were included in the study. A total of 80 cases diagnosed as Odontogenic tumors were included in the study. Results: As per the gender distribution 50 cases were found in male and 30 cases were found in females, with the ratio found to be 2:1. As per the locations mandible was more affected as compared to maxilla, with 55 cases to be found in mandible itself and 25 cases in maxilla which shows the ratio to be almost 2:1. Conclusion: Odontogenic tumors are very rare and consist of heterogeneous group of lesions which are derived from Odontogenic tissues. The present study provides the information related to the epidemiology and the geographic variation among the Odontogenic tumors in the central Indian population. There is essentiality to have the knowledge in relation to the data of the Odontogenic tumors so as to ascertain the risk group of population and to ascertain proper diagnosis of the lesion.
Impact of rock phosphate sources and their solubility by some microorganisms on Carum carvi plants productivity

Two field experiments were carried out during the two consecutive seasons of 2015/2016 and 2016/2017 at the Experimental Farm, Fac. Agric. , Al-Azhar Univ., Assuit to study the effect of some rock phosphate sources (Safaja and Soubaea), biofertilization type (Bacillus megatherium var. phosphaticum and Vesicular arbuscular mycorrhizal fungi) and their combinations on vegetative growth, yield components, oil production and some chemical constituents of caraway (Carum carvi L.) plant. The experimental design was a splitplot with three replicates. Effective some rock phosphate treatments considered the main plots, while microorganism treatments were the sub plots. Results showed an increase in vegetative parameters (plant height and total herb dry weight), yield components (fruit yield per plant and per feddan) and phosphorus percentage to Soubaea fertilization at level of 125 kg/feddan. While, the best values of volatile oil yield per plant and per feddan were obtained from Safaja rock phosphate at 200 kg/feddan. Furthermore, the highest values in this concern were obtained by the treatment of mixture of biofertilizers types compared to the other ones under study. Generally, among different combination treatments, treating caraway plants with Soubaea rock phosphate plus inoculation fruits by the mixture of biofertilizers proved to be the most promising treatment in fruit yield per feddan.
XPIV – Multiplane stereoscopic particle image velocimetry

We introduce the three-dimensional measurement technique (XPIV) based on a Particle Image Velocimetry (PIV) system. The technique provides threedimensional and statistically significant velocity data. The main principle of the technique lies in the combination of defocus, stereoscopic and multi-plane illumination concepts. Preliminary results of the turbulent boundary layer in a flume are presented. The quality of the velocity data is evaluated by using the velocity profiles and relative turbulent intensity of the boundary layer. The analysis indicates that the XPIV is a reliable experimental tool for three-dimensional fluid velocity measurements.
The Caregiving System and the Doctor-Patient Relationship : Responding to One ’ s Needs

The attachment theory states that human beings have in parallel an attachment system, an exploratory system and a caregiving system. The caregiving system is the counterpart of both the attachment and the exploratory systems. The caregiving system consists of providing safe haven to which the individual can go back when feeling threatened, and a secure base from which he/she can explore the environment. The caregiving system can also be experienced in the doctor-patient relationship. To be a care provider means to be available when one is most needed. Attachment patterns influence the doctor’s relationships, affecting the adherence and the illness management. Taking care of his/her patients in times of need is equivalent to activate the doctor’s own caregiving system to protect and secure the patient’s health and wellbeing. An open and available doctor means a more open, present, secure and confident patient.
Are Entrepreneurs More Optimistic Than Managers ? Evidence From a Lab-inthe-Field Experiment MARTIN Koudstaal

We study optimism among entrepreneurs, managers and employees using data from a large lab-in-the-field experiment. The results on two survey measures indicate that entrepreneurs are more optimistic than managers and employees in their dispositional optimism and their attributional style when bad events occur. Such optimism is not unique to entrepreneurs, though. More successful managers (e.g. CEOs) are similarly optimistic. Furthermore, examination of two incentivized measures of overestimation yields that both entrepreneurs and managers are more prone to overestimate their own ability or a future stock market closing price. On all four measures, however, employees are least optimistic.

The numerous demanding application of concrete is not readily met with Ordinary Portland Cement (OPC) alone. To meet up the demand and as well as ensured the green concrete durability, it has becomes necessary to incorporate mineral additions with the best combination of others by-product as replacement to improve the performance without jeopardizing the strength of the concrete. In the construction industry, OPC cement and river sand are used as important building material making it scarce and limited. Whereas, as for the cement is well known as the biggest culprits for emitting carbon dioxide (CO2). Hence, partial replacement of cement becomes a necessity as well as natural sand in concrete by waste material or by-product without compromising the quality of the end product. Partial replacement with Ground Granulated Blast furnace Slag (GGBS), Fly Ash (PFA), Silica Fumes (SILICA) incorporates with 100% of Quarry Dust (QD) as sand replacement. The usage of 100% QD with OPC+PFA+SILICA (Mix 2) produced more durable concrete with good temperature control and better furnishing than with 100% river. In addition to the cost effect benefit, the reduction in depletion of river sand, addressing environment and sustainability issues, it is a valuable contribution in creating a green concrete.
Understanding process modelling grammar continuance : a study of the consequences of representational capabilities

The graphical modelling of processes is of growing popularity and high relevance to organisations that seek to document, analyse and improve their business operations. This research investigates the phenomenon of continued user acceptance of the grammars that are used to build process models. It develops and tests a theory that can be used to explain and predict why users would opt to continue working with certain grammars in their process modelling efforts. This study builds on established theories, including the Technology Acceptance Model, Expectation-Confirmation Theory, Task-Technology Fit Theory and Representation Theory. These theories suggest that end users typically strive for tools that are useful and easy to use, which confirm their expectations through firsthand utility, and which match task requirements and individual abilities. Representation theory suggests that modelling grammars should be complete and clear in their capabilities to represent real-world domains. The research model has been designed by combining conceptual studies of acceptance and continuance theories with a representational analysis of the BPMN grammar, which is a recently ratified industry standard for process modelling and thereby of high practical relevance to process modelling practice. It further incorporates findings from nineteen semi-structured interviews with process modellers in Australia. The research model has been tested and validated by means of a web-based survey with 590 process modellers world-wide. This thesis contributes to the body of knowledge in a number of ways: First, it presents an empirically validated model of the factors determining a user's intention to continue using a process modelling grammar. Second, it measures the impact that grammar characteristics as well as user and task characteristics have on user evaluations of a process modelling grammar. Third, it presents empirical evidence on the consequences that perceived representational deficiencies entail on user perceptions of a process modelling grammar.
The Effect of ECB’s Corporate Sector Purchase Programme on CDS Premia-An Empirical Analysis

In response to the intensification of economic crises in the euro area, the European Central Bank (ECB), along with other central banks, has conducted both conventional and unconventional monetary policy. The most recent unconventional measure has been outright asset purchases under the corporate sector purchase programme (CSPP) targeting euro-denominated investment-grade bonds issued by non-financial corporations in the euro area. Using a Difference-in-Differences (DID) approach on a sample of euro-zone data I find that the CSPP initiative has consistently contained credit risk. In contrast, spillover effects to firms not subject to the CSPP policy are limited.
The Emergence and Transformation of Batkhela (Malakand) Bazaar: Ethnic Entrepreneurship, Social Networks, and Change in Disadvantageous Societies

This study is an inquiry into the emergence and transformation of Batkhela bazaar in the North West of Pakistan. It investigates the emergence of the bazaar in the face of historical conditions that were characterized by social stratification and political exclusivity. It then probes the transformation of Batkhela bazaar and it’s functioning in the current socio-political conditions. We investigate the above processes with a focus on entrepreneurs of the bazaar. Particularly we examine their efforts in challenging historical conditions during the emergence of the Batkhela bazaar and their continuous endeavor to keep the bazaar functioning. The study also reflects on the social and political embeddedness of the entrepreneurial activities of the bazaar. Through ethnographic methods, the study finds that the entrepreneurs use social networks of family and friends at different stages of entrepreneurship. Where family networks were more useful in the initial stage of business development, friendship networks were more useful in the later stages of business. Friendship networks being more diverse are not limited to co-ethnics as the literature on ethnic entrepreneurship would suggest but are increasingly cross-ethnic. Collectively, the family networks and the ever-defusing friendship networks, help ensure successful businesses in Batkhela. With these findings the study concludes that Batkhela bazaar is a monumental marketplace of the region that is socially and political embedded and contributes enormously to economic growth in the region.
