Expert Leaders in a Fast-Moving Environment This paper is an attempt to understand the effects of leaders on organizational performance. We argue for an ‘expert leader’ model of leadership. We differentiate between four kinds of leaders according to their level of inherent knowledge and industry experience. After controlling for confounding variables, teams led by leaders with extensive knowled...
Two experiments studied the effects of dietary chicory against gastrointestinal nematodes in cattle. In Experiment (Exp.) 1, stabled calves were fed chicory silage (CHI1; n = 9) or ryegrass/clover hay (CTL1; n = 6) with balanced protein/energy intakes between groups. After 16 days, all calves received 10 000 Ostertagia ostertagi and 66 000 Cooperia oncophora third-stage larvae (L3) [day (D) 0 p...
This paper addresses the issue if and to what extent young firms differ from incumbents regarding the use of non-standard employment, trust-based working time arrangements and overtime hours in the light of the qualitative changes of employment structures that are taking place in industrialized countries, such as rising shares of non-standard employment and borders between work and private life...
شانکر باکتریایی که بوسیله پاتوارهای pseudomonas syringae van hallایجاد میشود یکی از مشکلات جدی باغهای درختان میوه هستهدار میباشد. در این تحقیق طی سالهای 1391-1390 نمونه های دارای علائم شانکر از باغات بادام در استان خراسان رضوی جمع آوری شده و جداسازی باکتری انجام شد. عامل بیماری براساس آزمونهای گروه lopat و gatta، (pss)pseudomonas syringae pv. syringae شناسایی شد. شانزده جدایه خالص سازی...

ABSTRACT Designing around patents is prevalent but not often appreciated as a means by which promote economic development through competition. We provide novel empirical study of the extent and timing designing patent claims. filing rate incandescent lamp-related during 1878–1898 find that enforcement Edison’s lamp in 1891–1894 stimulated surge patenting. studied specific design features lamps ...
Food production and trade have become inseparable from requirements about product quality safety, as well social environmental aspects of processes. To demonstrate compliance with these requirements, firms adopt voluntary private certifiable management standards (CMS). How affect trade, organizational performance, employee outcomes has an area active research in the last decade. This paper anal...
A two-dimensional (2D) material system with both piezoelectric and ferromagnetic (FM) orders, referred to as a 2D ferromagnetism (PFM), may open up unprecedented opportunities for intriguing physics. Inspired by experimentally synthesized Janus monolayer MoSSe from MoS2, in this work, the CrBr1.5I1.5 dynamic, mechanical, thermal stabilities is predicted, which constructed CrI3 replacing top I a...
