Dynamic strategy: Investigating the ambidexterity–performance relationship

Purpose: This study aims to determine whether organisations in emerging economic contexts demonstrate ambidexterity for sustainable performance in the long term and what the effects of environmental turbulence are on the ambidexterity and sustainable performance relationship. Design/methodology/approach: This study used self-administered questionnaires and telephonic surveys. The sample consisted of profit-seeking organisations from many different industries within South Africa, including, but not limited to, manufacturing, business services, finance, hospitality and tourism, and retail and wholesale. The research was conducted during the 2017 financial year. Findings/results: It was found that moderate to strong relationships exist between the two sub-dimensions of ambidexterity and sustainable performance. The findings depict a strong relationship between exploration and exploitation as the sub-dimensional constructs of ambidexterity, reinforcing existing literature on simultaneous exploration and exploitation. There was no statistically significant information, indicating that environmental turbulence moderates the ambidexterity and sustainable performance relationship. Practical implications: Considering the strong positive relationship between the two sub-dimensions of ambidexterity and sustainable organisational performance, it is advisable for management of South African organisations to focus on ambidextrous strategies for sustaining performance in turbulent environments. Originality/value: This study contributes to the limited body of knowledge investigating ambidexterity as a dynamic capability in an emerging economic context. Moreover, this study contributes to clarify the ambidexterity and sustainable performance relationship in terms of whether organisations can simultaneously explore and exploit and what type of relationship exists between ambidexterity and sustainable performance as previous studies delivered mixed results.
Experimental and Numerical Investigation of the Levitation Force Between Bulk Permanent Magnet and ${\rm MgB}_{2}$  Disk

The experimental investigation of the levitation force between a Permanent magnet (PM) and MgB2 disk prepared by means of the Reactive Mg Liquid Infiltration is presented. Both FC and ZFC levitation in the temperature range from 21 K to 37 K are considered. The long term behavior of the levitation force is also investigated. A numerical model is developed in order to investigate the electrodynamics of levitation. The hysteretic behavior of the levitation force is related to the dynamic of current penetration inside the MgB2 disk by means of the numerical model.
Corporate profitability-working capital management tie: empirical evidence from pharmaceutical sector of Pakistan

The importance of working capital management in generating the corporate profitability cannot be disregarded. This study aims to empirically investigate the impact of working capital management on the profitability of pharmaceutical sector of Pakistan. The study has taken secondary data covering a period of six years from 2011 ? 2016. Current ratio, cash conversion cycle and current assets to total assets were taken as independent variables to represent working capital management and return on the asset taken as the dependent variable to represent corporate profitability. Through panel regression analysis, this study has found a significant impact of current ratio and cash conversion cycle and current assets to total assets have an insignificant impact on corporate profitability. These results give an insight of managing corporate profitability by considering current ratio and cash conversion cycle. This study should be beneficial for the pharmaceutical sector of Pakistan as performance and survival of this sector is important for investor and for the health of the general public.
Herpes-type virus particles in tissue culture of Kaposi's sarcoma from different geographic regions.

Typical herpes-type virus particles were observed in 5 of 8 selected tissue culture lines derived from different cases of Kaposi's sarcoma from 2 equatorial African regions, Congo and Uganda. Common and different traits of cellular morphology related to viral involvement were found. In one line, morphologic aspects and preliminary immunologic characterization suggested a virus resembling cytomegalovirus. The other 4 cases presented one important trait in common: The appearance of viruses (at an early stage in lines 13, 16, 19) in undifferentiated cells that resembled fibroblastoid or macrophage elements. -J Natl Cancer Inst 49: 1509-1526, 1972.
The Value of People, Place and Possibilities: A Multiple Case Study of Rural High School Completion

The U.S. national average for high school graduation falls far below that of many other industrialized countries and is marked by signifi cant graduation rate gaps between students of higher- and lower-socioeconomic status and students attending suburban vs. rural or urban schools (Rumberger, 2011). The failure of youth to complete high school is a problem both for them and for the greater society as high school dropouts have lower earning power, higher rates of incarceration, and poorer health, with all the attendant consequences for themselves, their families, and society (Hauser & Koenig, 2011; McLaughlin, Embler, Hernandez, & Caron, 2005; Purcell, East, & Rude, 2005). What are the qualities of classroom, school, and district processes and practices in rural high schools with higher-thanaverage graduation rates? How do these processes and practices compare with rural schools with histories of average graduation rates? In this study, six schools were sampled for a multiple case study of rural high school completion. Four had higher-than-average graduation rates, while two had average rates. All six schools were visited by site teams who conducted 63 interviews and collected documentary evidence of practices and processes related to high school graduation. Using cross-case analytic procedures, we found several important contrasts between the two sets of sample schools. Differences in graduation outcomes in these rural schools were associated with (1) the qualities of academic goals, expectations, and learning opportunities; (2) the nature of individual and collective educator effi cacy; (3) the strategies educators used to develop and maintain family relationships and engage community members; and (4) mechanisms for adapting instruction and employing interventions for students at risk of dropping out.

AUDITORY PERCEPTION OF ROAD TRAFFIC NOISE

Our perceptual spatial representation of road traffic noise is revealed in this study by a dissimilarity factor analysis, on a corpus of 14 loudness equalized stimuli, representative of urban and suburban environments. A cluster analysis is carried out too, to gather these sounds into homogeneous classes according to the aroused stress. First dimension reveals a perception in accordance with categorization results, the stimuli being separated into two groups: suburban noises and typical urban sounds. In each group only, listeners perceive physical properties of the signal. Suburban stimuli dissimilarities are based on the number of identified sources. They explain the second factor, but the third dimension, which seems to be a spectral one, concerns the other group. For the covering abstract see ITRD E107776.

The V-Antigen of Yersinia Forms a Distinct Structure at the Tip of Injectisome Needles

Many pathogenic bacteria use injectisomes to deliver effector proteins into host cells through type III secretion. Injectisomes consist of a basal body embedded in the bacterial membranes and a needle. In Yersinia, translocation of effectors requires the YopB and YopD proteins, which form a pore in the target cell membrane, and the LcrV protein, which assists the assembly of the pore. Here we report that LcrV forms a distinct structure at the tip of the needle, the tip complex. This unique localization of LcrV may explain its crucial role in the translocation process and its efficacy as the main protective antigen against plague.
Socially Responsible Corporate Customers

Abstract Corporate customers are an important stakeholder in global supply chains. We employ several unique international databases to test whether socially responsible corporate customers can infuse similar socially responsible business behavior in suppliers. Our findings suggest a unilateral effect on corporate social responsibility (CSR) only from customers to suppliers, an evidence further supported by exogenous variation in customers’ close-call CSR proposals and by product scandals. Customers exert influence on suppliers’ CSR through positive assortative matching and their decision-making process. Enhanced collaborative CSR efforts help improve operational efficiency and firm valuation of both customers and suppliers but increase only the customers’ future sales growth.
School-age children talk about chess: does knowledge drive syntactic complexity?

PURPOSE This study examined language productivity and syntactic complexity in school-age children in relation to their knowledge of the topic of discussion-the game of chess. METHOD Children (N = 32; mean age = 10;11 [years;months]) who played chess volunteered to be interviewed by an adult examiner who had little or no experience playing chess. Children's chess knowledge and experience was assessed, and each child was classified as a novice or an expert player. Each child participated in 3 speaking tasks: General Conversation, Chess Conversation, and Chess Explanation. Interviews were audiorecorded, transcribed into Systematic Analysis of Language Transcripts (J. F. Miller & R. Chapman, 2003), segmented into T-units, and coded for finite clauses. Each speaking task was analyzed for total T-units; mean length of T-unit; clausal density; and nominal, relative, and adverbial clause use. RESULTS Total T-units, mean length of T-unit, clausal density, and the use of each type of subordinate clause was substantially higher in the Chess Explanation task compared with the Chess Conversation task or the General Conversation task. Compared with the novices, the experts knew more about chess, had played longer, and were stronger players. Nevertheless, the novices and experts did not differ on any of the language factors for any of the speaking tasks. CONCLUSIONS Language productivity and syntactic complexity in school-age children are strongly influenced by the speaking task. When children are presented with a motivating and challenging topic, they rise to the occasion to explain the finer details of it to a naïve adult.
Effect of Different Denture Cleansers on Surface Roughness of Acrylic Denture Base Materials

Objectives: The purpose of this investigation was to evaluate the effect of different denture cleansers and distilled water on surface roughness of self- and heat-polymerized acrylic denture base materials.Materials and methods:Specimens were prepared from self- and heat-polymerized acrylic resin denture base materials and distributed into different groups of 15 each. Specimens of each group were immersed in distilled water as control and in three different denture cleansers according to the manufacturer's instructions and immersion was repeated 7 times over 7 days. The reading of surface roughness was recorded for all the specimens using a 3D optical noncontact surface profiler based on noncontact scanning interferometry to evaluate roughness.Results:No significant difference was found in the average surface roughness of heat-polymerized resins after immersion in denture cleansers (P>0.05). One-way ANOVA revealed significant difference in self-polymerized acrylic resin base material among different cleansers. Tukey Post Hoc test for multiple comparison showed that the mean of surface roughness of self-polymerized resin base immersed in Corega was significantly greater than the control group (P = 0.007). Significant difference was noticed in the interaction between the materials and the solutions (P=0.027). Self-polymerized resins immersed in distilled water had a significant decrease in surface roughness compared with the heat-polymerized resins (P<0.05). Conclusion:Immersion of acrylic denture base materials in the tested denture cleansers had no significant effect on the surface roughness of the denture base materials except for self-polymerized resins, which immersed in Corega.Running Title: Denture cleansers and roughness of denture baseÂ Â Â
Computation method for complete D-stability intervals of a class of matrices based on generalization of the stability feeler

In this paper we study the robust D-stability of single-parameter polynomially-dependent matrices. D-stability of a matrix means that all the eigenvalues are in a prescribed open region, which is symmetric with respect to the real axis in the complex plane. We propose a method based on generalization of the stability feeler. By using this method, we can obtain complete D-stability intervals for a class of single-parameter polynomially-dependent matrices. This method does not require that a nominal matrix is stable. Moreover, we show an application to the analysis of robust D-stability in a physically motivated example.
Equivalent Outcomes for Pediatric Heart Transplantation Recipients: ABO‐Blood Group Incompatible versus ABO‐Compatible

ABO‐blood group incompatible infant heart transplantation has had excellent short‐term outcomes. Uncertainties about long‐term outcomes have been a barrier to the adoption of this strategy worldwide. We report a nonrandomized comparison of clinical outcomes over 10 years of the largest cohort of ABO‐incompatible recipients. ABO‐incompatible (n = 35) and ABO‐compatible (n = 45) infant heart transplantation recipients (≤14 months old, 1996–2006) showed no important differences in pretransplantation characteristics. There was no difference in incidence of and time to moderate acute cellular rejection. Despite either the presence (seven patients) or development (eight patients) of donor‐specific antibodies against blood group antigens, in only two ABO‐incompatible patients were these antibodies implicated in antibody‐mediated rejection (which occurred early posttransplantation, was easily managed and did not recur in follow‐up). Occurrence of graft vasculopathy (11%), malignancy (11%) and freedom from severe renal dysfunction were identical in both groups. Survival was identical (74% at 7 years posttransplantation). ABO‐blood group incompatible heart transplantation has excellent outcomes that are indistinguishable from those of the ABO‐compatible population and there is no clinical justification for withholding this lifesaving strategy from all infants listed for heart transplantation. Further studies into observed differing responses in the development of donor‐specific isohemagglutinins and the implications for graft accommodation are warranted.
Adaptation of the maternal heart in pregnancy

The first haemodynamic change during pregnancy seems to be a rise in heart rate. Starting between two and five weeks this continues well into the third trimester. Stroke volume increases slightly later than the heart rate and continues throughout the second trimester after an augmentation of venous return and a fall of systemic vascular resistance and afterload. Myocardial contractility is probably slightly increased. During the third trimester there is relatively little change in these cardiac indices. After delivery there is a very early and dramatic reduction in volume loading followed by a return towards normal cardiac output. Structural changes within the heart reflect the volume loading of pregnancy and include dilatation of the valve ring and increase in myocardial thickness. Post partum resolution of the ventricular hypertrophy seems to take longer than the rest of the post partum changes. The resemblance to the cardiovascular changes associated with training and exercise are fascinating and worthy of further study.
PEMBIAYAAN BANK SYARIAH

This paper aims to describe more deeply the understanding of Islamic bank financing. As a country that is predominantly Muslim, it should be expected that the presence of Islamic banks in Indonesia is something to be expected. A bank is an industry that operates in the field of trust, which in this case is a financial intermediary between debtors and creditors. Islamic banks function as intermediary institutions, which function to collect funds from the community and redistribute these funds to the people who need them in the form of financing. namely to collect funds from the community and redistribute these funds to the people who need them in the form of financing. Financing is the largest source of income for Islamic banks, but at the same time is the biggest source of risk for business operations. Therefore, these funds must be used correctly, fairly, and must be accompanied by bonds and clear conditions that are mutually beneficial for both parties.
Differential effects of estrogen/androgen on the prevention of nonalcoholic fatty liver disease in the male rat[S]

It is important to clarify the distinct contributions of estrogen/estrogen receptor (ER) and androgen/androgen receptor (AR) signaling and their reciprocal effects on the regulation of hepatic lipid homeostasis. We studied the molecular mechanisms underlying the preventive effects of estradiol (E2), dihydrotestosterone (DHT), or E2+DHT on high-fat diet-induced nonalcoholic fatty liver disease (NAFLD) in an orchidectomized Sprague-Dawley (SD) rat model. E2 is shown to be associated with decreased fatty acid synthesis in hepatic zone 3-specific manner by increasing the phosphorylation of acetyl coenzyme-A carboxylase via an ERα-mediated pathway. DHT is shown to be associated with decreased lipid accumulation and cholesterol synthesis in a hepatic zone 1-specific manner by increasing expression of carnitine palmitotyltransferase1 and phosphorylation of 3-hydroxy-3-methyl-glutaryl-CoA reductase via an AR-mediated pathway. E2+DHT showed an additive positive effect and normalized all three impaired zones of the liver. Gene expression changes in human severe liver steatosis were similar to those of experimental rat NAFLD. Steroids reversed the histopathological NAFLD changes, likely by decreasing fatty acid and cholesterol synthesis and increasing β-oxidation. The diverse steroid effects (ER/AR) on NAFLD prevention in male rats indicate the potential applicability of ER/AR modulators for NAFLD treatment.
Proprioceptive leg reflexes in cockroaches.

1. Cockroaches have been found to run with stepping frequencies up to 20 cyc. /sec. At the higher frequencies mesothoracic amputees do not exhibit the gait adaptations characteristic at lower frequencies. 2. Proprioceptive leg reflexes can follow input frequencies at more than 20 cyc. /sec. , without phase shift over the frequency spectrum. The myotatic reflex output shows some phase lead with respect to leg position. 3. The contralateral leg responds less strongly and is 180° out of phase with respect to the response of the stimulated leg. Legs in other segments show even weaker responses which are variable in sign. 4. The nervous reflex effects are competent to influence co-ordination at all frequencies found in normal locomotion. The muscular abilities presumably set a limit to higher speeds of running.

Screening for Post-Partum Depression in a Community Sample

Objective This study undertook to estimate the prevalence of post-partum depression in the community by means of telephone screening. Demographic correlates of post-partum depression were also investigated. Method The sample was identified through two community health centres. Over a period of 17 months, 1559 childbearing women were screened at six weeks post-partum, using the ten-item Edinburgh Postnatal Depression Scale (EPDS). Results The prevalence of post-partum depression was estimated to be 6.2%, using a outpoint of 10 on the EPDS, and 3.4% using the more stringent cut point of 12. Women who were not working, or those with lower occupational status, were at greater risk for depression. Recent immigrants, particularly those who were not working or who had given birth to a second child, were also at higher risk. Conclusion Telephone screening for post-partum depression is feasible, and can aid in the identification of women at risk.
The role of extrapleural pneumonectomy for malignant pleural mesothelioma: reviewing 20-years of experience

Malignant pleural mesothelioma (MPM) is a very aggressive malignancy with a poor prognosis, requiring a complex treatment. Despite the fact that asbestos, the main etiologic factor, has been banned in most industrial countries for several decades, its global incidence is still increasing and MPM is expected to become a significant problem in third world countries in the next decades (1). In an adequately selected group of patients with resectable disease, a multimodality approach including neoadjuvant chemotherapy with platinum and anti-folate doublet, followed by surgical resection is part of the most recent guidelines (2-5). Due to the tumor’s anatomical restraint with proximity to the heart and the big vessels, the chest Original Article
Short Selling Bans and Market Liquidity around the World: Evidence from the 2007-09 Crisis

Most stock exchange regulators around the world have reacted to the financial crisis of 2007-2009 by imposing bans or regulatory constraints on short-selling by market participants. We use the large amount of evidence generated by the introduction and lifting of these bans to investigate the effects of short-selling bans on liquidity and price discovery. The enactment and lifting of bans at different dates in different countries, in some countries for financial stocks only, and often with different degrees of stringency, enables us to use panel data techniques to investigate their effects. We also investigate the cross-sectional effect of bans on liquidity of stocks with different market capitalization and different volatility. Finally, we analyze the effect of bans on other measures of market quality, such as price discovery and the skewness of stock returns. Short-selling is an integral part of the trading strategies of institutional investors, in particular hedge funds. Our research has the potential to show to regulators that banning short selling has detrimental effects on market quality and, as a result, it is not an appropriate policy action.
