Organizational unlearning and knowledge transfer in cross-border M&As: the mediating role of knowledge integration from a routine-based view

Purpose: This paper aims to explore the relationships between organizational unlearning and knowledge transfer in cross-border mergers and acquisitions (M&As) from a routine-based view. The study also stresses the mediating role that knowledge integration capability plays in this relationship. Design/methodology/approach: In all, 178 samples were collected from Chinese multinational corporations that experienced cross-border M&As. In addition, the bootstrap method was used to test the mediating role of knowledge integration capability. Findings: The empirical results indicate that knowledge integration capability is the crucial link between organizational unlearning and knowledge transfer. Specifically, this capability goes beyond the direct effect of organizational unlearning on knowledge transfer and points to the importance of enhancing knowledge integration capability. In turn, knowledge integration capability has a significant influence on knowledge transfer. The study finds that knowledge integration capability mediates the relationship between organizational unlearning and knowledge transfer. Originality/value: This study adopts a routine-based view to develop a theoretical model for examining the relationship between organizational unlearning, knowledge integration capability and knowledge transfer in the context of cross-border M&As. This model provides new insights for a routine-based understanding of the important mediating role of knowledge integration capability for knowledge transfer and the effects of this role on the specific knowledge transfer, i.e. technological, marketing and managerial knowledge.
Soil nitrogen changes under continuously grazed legume-grass pastures in subtropical coastal Queensland

Net changes in total soil nitrogen were measured in 1.2 to 2.4 hectare paddocks of legume-grass pastures at three sites. The sites and pastures were (a) Rodd's Bay-a pasture of Stylosanthes humilis and Heteropogon contortus, (b) Samford-a pasture of Phaseolus atropurpureus cv. Siratro, Digitaria didactyla, and Axonopus affinis and (c) Beerwah-a pasture of Desmodiam intorum cv. Greenleaf, D. uncinatum cv. Silverleaf, Lotononis bainesii, Trifolium repens, Digitaria decumbens, Chloris gayana, Paspalum dilatatum, and P. commersonii. At Rodd's Bay, the changes under pasture containing Stylosanthes humilis varied greatly according to seasonal conditions. During a period of 29 months that covered three successive growing seasons with below-average rainfall, short-term fluctuations in total soil nitrogen gave a net decrease of 70 kg ha-1 (0.95 confidence limits ¦30), an average of 29 (¦ 12) kg ha-1 year-1. In the following three-year period, which included two very wet growing seasons and one very dry one, soil nitrogen increased by an average of 30 ¦ 10 kg ha-1 year-1. Over a period of four years, soil nitrogen increased by an average of 44 ¦ 9 kg ha-1 year-1 under Phaseolus atropurpureus at Samford, and 81 ¦ 10 kg ha-1 year -l under the mixture of legumes at Beerwah.
67 Suicidality and exposure to school-based violence among a nationally representative sample of Asian American and Pacific Islander youth

Statement of Purpose Asian Americans and Pacific Islanders (AAPI) are the fastest growing racial/ethnic minority group in the U.S. However, less focus has been paid to the rates of suicidal behaviors among AAPI youth, despite estimates placing suicide as the second leading cause of death among AAPI youth (15–24 years). At the same time, exposure to school-based violence has a long-term negative impact on youth outcomes. And recent research has noted that AAPI youth are more likely to be victimized in schools than their non-AAPI peers. The current study expands on the limited existing research and examines the relationship between suicidal behavior and exposure to school-based violence among a national sample of AAPI high school students. Methods We conducted a secondary analysis of the CDC’s most recent Youth Risk Behavior Surveillance System data (n=14,765). Results Results demonstrated that the prevalence of AAPI youth engaging in suicidal behaviors does not differ significantly from other demographic subgroups. Further, a significant correlation between exposure to school-based violence (including having been threatened with a weapon and a perceived lack of safety at school) and four suicidal behaviors was observed among this sample of AAPI youth: considered suicide attempt: r=0.237, p< 0.001; made a suicide plan: r=0.237, p< 0.001; attempted suicide: r=0.164, p<0.001, had a suicide attempt that resulted in injury: r=0.147, p<0.001. Conclusions Our findings confirm that AAPI youth are engaging in suicidality behaviors and experiencing school-based violence at rates comparable to non-AAPI youth. We also demonstrate that a significant relationship between exposure to school violence and suicidality persists for this subgroup. Significance Implications for integrating existing mental health practices with school-based violence prevention efforts and that are tailored specifically to the needs of AAPI youth are discussed.
Response of soybean leaf water relations to tropospheric ozone

Tropospheric O3 and water stress cause significant reductions in crop growth and yield. The effects of chronic O3 exposures on leaf water relations have been less thoroughly studied. Soybeans were grown in two years in open-top field chambers equipped to control O3. The seasonal mean O3 concentrations for the charcoal-filtered controls and supplemental O3 treatments were 24 and 83 nL∙L−1 for the first year (1990) and 20 and 99 nL∙L−1 for the second year (1992). In 1990 leaves were sampled during four intervals of the 106-d growing season and subjected to potential–volume analysis. In 1992, leaves were sampled over a 3-week period, centered on 49 days after planting for potential–volume analysis as well as for midday xylem pressure potentials and leaf conductance. Ontogenetic changes in most of the parameters were large compared with treatment effects. O3 treatment consistently caused decreased symplastic volume, specific leaf mass, and tissue elasticity. In 1992, these effects were accompanied by decrease.
Association between triclosan levels and white blood cell counts in US adults from NHANES, 2011–2012

Triclosan is a broad-spectrum antimicrobial agent used in a multitude of healthcare and consumer products. Epidemiological studies link triclosan exposure to several adverse health outcomes including alterations in thyroid function and an increased risk for allergies and asthma suggesting an immunomodulatory role for the endocrine disrupting synthetic chemical. The effects of triclosan on the human immune system, particularly on the levels and function of white blood cells, have yet to be fully characterized. Using cross-sectional data from the NHANES 2011–2012 survey, we examined the relationship between triclosan exposure levels and white blood cell counts in adults 18–65 years of age. Results from multivariable linear regression analysis show lack of a statistically signficant association between urinary triclosan levels and white blood cell counts (β = −0.0007, p = 0.90, 95% CI = −0.012, 0.010). Findings may demonstrate an absence of association or may indicate that triclosan exposure levels were too low to have a significant detectable impact on white blood cell counts. Considering that prior animal and epidemiological studies have established links between triclosan exposure and alterations in immune system parameters and susceptibility to allergic diseases, the effects of triclosan exposure on the immune system should continue to be evaluated.
Stomatal responsiveness to leaf water status in common bean (Phaseolus vulgaris L.) is a function of time of day

Stomatal response to leaf water status was experimentally manipulated by pressurizing the soil and roots of potted common bean plants enclosed in a custom-built root pressure chamber. Gas exchange was monitored using a wholeplant cuvette and plant water status using in situ leaf psychrometry. Bean plants re-opened their stomata upon pressurization, but the extent of re-opening was strongly dependent on the time of day when the soil was pressurized, with maximum re-opening in the morning hours and limited re-opening in the afternoon. Neither leaf nor xylem abscisic acid concentrations could explain the reduced response to pressurization in the afternoon. The significance of this phenomenon is discussed in the context of circadian rhythms and of other recent findings on the ‘apparent feed-forward response’ of the stomata of some species to vapour pressure deficit.
Herbal compounds increased tHe level of cd34 positive cells in peripHeral blood - an experimental work

Peripheral blood stem cells (PBSC) could contribute to tissue regeneration through the ability to form somatic cells. CD34 positivity is regarded as stem cell (SC) or endothelial progenitor cell (EP) marker. According to literature natural substances could increase the release of CD34 positive (CD34+) cells. In this study we investigated the basic rate of CD34+ cells in peripheral blood of CBA/Ca (H-2k haplotype) and BALB/c inbred mice by flow cytometry. Then we treated the mice with a new mixture of medical herbs, and we measured the level of CD34+ cells at 1, 3, 6, 18 and 24 hours after the treatment. A biological rhythm in the untreated blood was detected. Moreover the used herbal compounds increased the number of CD34+ cells.Although SC number is individually and highly variable in peripheral blood, the fluctuation could be used as a biomarker like the other compounds of peripheral blood in different aspects in risk assessment.
Pulsed Levosimendan in advanced heart failure due to congenital heart disease: a case series

Abstract Background Levosimendan is a non-adrenergic calcium-sensitizing agent with positive inotropic and vasodilatory effects. Its use in acute decompensation of heart failure is established. Good evidence now exists for repetitive infusions of Levosimendan to improve symptoms and reduce hospitalization in advanced heart failure (AdHF) populations. Its use in heart failure resulting from congenital heart disease is not yet commonplace. Case summary We present three cases in which pulsed Levosimendan was used in the management of AdHF secondary to underlying congenital heart disease. There was symptomatic and biomarker evidence of improvement. Discussion Intermittent Levosimendan may represent a valuable therapy to reduce hospitalization and improve quality of life in adults with congenital heart conditions.
The relationship between talent management practices and retention of generation ‘Y’ employees: mediating role of competency development

Abstract In a competitive marketplace, retention of talented and younger employees is a challenge for organizations. Thus, it becomes important for organizations to execute employees’ development strategies to retain Generation Y employees. The goal of this research is to analyze the effect of talent management (TM) practices i.e. mentoring, strategic leadership, social media, and knowledge sharing on the intention to stay of generation Y employees and strengthening this relationship by investigating the mediating role of competency development. A total of 372 employees of generation Y participated in the study. The data were analyzed through the PLS-SEM model using smartPLS-3 software. Findings reveal that TM practices: mentoring, strategic leadership, social media positively affect the intention to stay of generation Y employees, while knowledge sharing has no significant effect on the intention to stay. Competency Development mediates the relationship between strategic leadership, social media, knowledge sharing and intention to stay. However, competency development does not significantly mediate the relationship between mentoring and intention to stay.
Nonlinear Production Networks with an Application to the COVID-19 Crisis

We study the effects of negative supply shocks and shocks to the composition of final demand on aggregate output in a disaggregated neoclassical model with multiple sectors, factors, and input-output linkages. We show how nonlinearities associated with complementarities in consumption and production amplify the effect of negative supply shocks by creating supply bottlenecks and disrupting supply chain networks. These nonlinearities are particularly potent when the shocks are more heterogeneous as the worst-affected sectors drag down the other sectors. Nonlinearities are strengthened when changes in preferences lead households to tilt the composition of their demand towards the crippled sectors directly and indirectly through their supply chains. And nonlinearities are further intensified when factors cannot easily be reallocated across sectors to reinforce weak links. A quantitative investigation suggests that nonlinearities may amplify the impact of the Covid-19 shock by between 10\%-100\%, depending on the horizon of analysis and the exact size of the shocks.
Connectivity of Isotropic Systems

Isotropic systems are structures that unify some properties of Cregular graphs and autodual properties of binary matroids. Thus an isotropic system can be associated to any pair of dual binary matroids and also to any 4-regular graph. However, there are isotropic systems that cannot be obtained in this way. Isotropic systems are introduced in [2] and [3]. The connectivity of a matroid in Tutte’s sense [9] is autodual. Thus we define for each integer k > 0 the notion of a k-connected isotropic system in such a way that any isotropic system S derived from a pair of dual binary matroids is kconnected if and only if these matroids are k-connected. If S is derived from some 4-regular graph G, then if S is k-connected, G is cyclically 2kedge connected. The converse is true if and only if k I 3. This is similar to the relation between the connectivity of a graph and those of its cycle-matroid. There is another connection between isotropic systems and graph theory. To any isotropic system S is associated a set of simple graphs called its fundamental graphs. If S is associated to a pair of dual binary matroids ( M , M*), then we obtain a fundamental graph (but not all) of S by constructing a bipartite graph whose color classes are a base B and the complementary cobase B’, with an edge xy, x E B, y E B’, if and only if x belongs to the fundamental circuit of M contained in B + { y } . If F is a fundamental graph of an isotropic system S, then we show that S is 3-connected if and only if F is prime in the sense of Cunningham’s decomposition theory of graphs [S]. A theorem of Tutte [lo] says that if a matroid is 3-connected, then it has some 3-connected minor with one cell less, unless it is either a wheel or a whirl. We show that a similar result for 3-connected isotropic systems can be derived from a reduction theorem for prime graphs stated in [4]. But isotropic systems have three minors at each cell when matroids have two. This implies that we find a single minimal 3-connected isotropic system instead of the two infinite families for matroids. If the 3-connected system S derives from a cyclically 6-edge connected +regular graph G, the interpretation of the preceding theorem is obtained by introducing j-minors. A j-minor of G at a vertex u is obtained by splitting v into two vertices of degree 2 and contracting one edge incident to each of these vertices in order to get a new 4-regular graph. The interpretation is that unless G is a complete graph of order 5, then one of its j-minors is cyclically 6-edge connected. We give a direct proof of this result in the last section of this paper.
Early sulfide saturation is not detrimental to porphyry Cu-Au formation

Ore-forming magmas are commonly considered to have been unusually metal rich. Because Cu and Au are strongly chalcophile, early sulfide saturation has been regarded as detrimental to porphyry Cu-Au mineralization. Here we demonstrate, based on amphibole-rich cumulate xenoliths and amphibole megacrysts from the Tongling porphyry(-skarn) Cu-Au mining district in southeastern China, that this view is not necessarily correct. Age data combined with petrological and geochemical evidence suggest that the mineralizing magmas at Tongling underwent significant fractional crystallization of amphibole, clinopyroxene, and magmatic sulfides in the middle to lower crust. The fact that the silicate melts nevertheless were able to produce substantial porphyry(-skarn) Cu-Au deposits implies that the formation of metal-rich cumulates at depth was not detrimental to their fertility. On the contrary, the common association of porphyry Cu (Au, Mo) deposits with high-Sr/Y magmas suggests that amphibole fractionation at depth even promotes the mineralization potential, despite the likely loss of metals.
Initiation, Persistence, and Cessation of the Series of Intracellular Ca2+ Responses during Fertilization of Bovine Eggs

A long-lasting series of transient rises in intracellular Ca2+ concentration ([Ca2+]i) were recorded with Ca2+ imaging during fertilization of bovine eggs matured in vivo or in vitro. The first Ca2+ response could be recorded in zona pellucida-free eggs within 1 min after sperm-egg contact, when a preceding slow [Ca2+]i rise reached 150-170 nM. The response had the peak of 565 ±32 nM (n=15; maximum 780 nM) and the duration of 4-6 min, being significantly larger and longer than any succeeding response (359 ± 12 nM, n=68; 2 min). The series of Ca2+ transients occurred at constant intervals of 19-20 min without attenuation in the magnitude for more than 9 h. Ca2+ transients became smaller progressively during pronuclear migration and nuclear envelope breakdown, and no response occurred in 2-cell embryo. In unfertilized eggs, injection of inositol 1, 4, 5-trisphophate (InsP3) induced a Ca2+ transient and the sulfhydryl reagent thimerosal caused repetitive Ca2+ transients. These responses were markedly inhibited or blocked by preinjection of a monoclonal antibody to the mouse InsP3 receptor. However, sperm-induced responses were not blocked in 2/3 of eggs examined. Another mechanism may be involved in addition to InsP3-induced Ca2+ release from intracelluar stores.
Studies on the effect of exogenous application of salicylic acid on post-harvest
quality and shelf life of tomato fruit Cv. Abhinav

An investigative research experiment was undertaken to study the effect of exogenous application of salicylic acid on tomato fruit of Cv. Abhinav during its storage period at 24C. The fresh tomato fruits (Lycopersicon esculentum Mill.) of Cv. Abhinav were harvested at the proper stage of physiological maturity. The fruits were washed thoroughly with clean water followed by fungicidal treatment of 500 ppm benomyl before salicylic acid treatment. Thereafter, the fungicide treated tomato fruits were subdivided into four different lots and then immersed in salicylic acid (SA) solutions at 50, 100, 150 and 200 ppm concentrations for 30 mins respectively and kept for storage studies along with control fruits. During the storage period, the observations were recorded at frequent intervals for various physico-chemical parameters in which tomatoes treated at 200ppm salicylic acid concentration found significant with respect to the lower physiological loss in weight (10.3%), a gradual increase in TSS and colour (h) from 1.4 to 3.3Brix and -3.63 to 2.59 respectively. Moreover, the considerable decrease was observed in titrable acidity from 1.34 to 0.14%, Ascorbic Acid (SA) content from 73.14 to 22.10 mg/100 g and texture in terms of firmness decreased from 354 to 96 gf. The total phenolic content of 200 ppm salicylic acid treated tomatoes showed a gradual decrease from 3.79 to 3.14 mg GAE/g and lycopene content increased slowly from 7.01 to 12.31 mg/100 g therefore, found significant as compared to rest of the treatments and control fruits.
Retrieval of Cloud Liquid Water Using Microwave Signals from LEO Satellites: A Feasibility Study through Simulations

A novel approach, using low Earth orbit (LEO) satellite microwave communication links for cloud liquid water measurements, is proposed in this paper. The feasibility of this approach is studied through simulations of the retrieval system including a LEO satellite communicating with a group of ground receivers equipped with signal-to-noise ratio (SNR) estimators, a synthetic cloud attenuation field and a tomographic retrieval algorithm. Rectangular and Gaussian basis functions are considered to define the targeted field. Simulation results suggest that the proposed least-squares based retrieval algorithm produces satisfactory outcomes for both types of basis functions. The root-mean-square error of the retrieved field is around 0.2 dB/km, with the range of the reference field as 0 to 2.35 dB/km. It is also confirmed that the partial retrieval of the cloud field is achievable when a limited number of receivers with restricted locations are available. The retrieval outcomes exhibit properties of high resolution and low error, indicating that the proposed approach has great potential for cloud observations.

Assessing Yield and Yield Stability of Hevea Clones in the Southern and Central Regions of Malaysia

Increased volatility in global rubber prices has led to declining Malaysian rubber production and smallholder income. Identifying rubber clones that can produce a consistently high yield in various environments is one of the potential measures to alleviate the impact of price fluctuations and improve smallholder livelihoods. In this study, we assessed rubber yields and yield stability of 37 rubber tree clones at two major production regions in Malaysia: Kota Tinggi (Southern region) and Sungai Buloh (Central region). In addition, we assessed relationships between climate data with rubber yields. Rubber yield and stability differed widely by clone, but showed relatively consistent trends across regions. Clones RRIM 2007, PB 260, and RRIM 2012 were high yielding in both regions and had high stability. Conversely, clone RRII 308 had the lowest mean yield across both regions and low stability. Mean annual yields showed a negative relationship with rising minimum temperatures, declining by ~3 g per tapping per tree (g t−1 t−1) per 1 °C rise in minimum temperature. Our findings highlight clones capable of achieving stable high yields. This information may be useful for breeders and agronomists in identifying germplasm and traits for further development. Further, this information can be used to assist clone recommendations to smallholders in these regions to mitigate the dual impacts of climate change and market volatility.
