Preparation and characterization of dummy-template molecularly imprinted polymers as potential sorbents for the recognition of selected polybrominate…

2018

The main aim of this work was to conduct the preliminary/basic research concerning the preparation process of a new dummy molecularly imprinted polymer (DMIP) materials. Developed DMIPs were proposed as a sorption material in solid-phase extraction (SPE) technique for recognition of selected low mass polybrominated diphenyl ethers (PBDEs) – PBDE-47 and PBDE-99. Four new DMIPs were synthesized employing bulky polymerization technique by application of structural analogue of low mass PBDEs - 4,4′-Dihydroxydiphenyl ether, as a dummy template. The DMIPs and corresponding non-imprinted polymers were prepared using different functional monomers: methacrylic acid; methyl methacrylate and different…

Positive selection at codon 38 of the human KCNE1 (= minK) gene and sporadic absence of 38Ser-coding mRNAs in Gly38Ser heterozygotes

2009

Abstract Background KCNE1 represents the regulatory beta-subunit of the slowly activating delayed rectifier potassium channel (IKs). Variants of KCNE1 have repeatedly been linked to the long-QT syndrome (LQTS), a disorder which predisposes to deafness, ventricular tachyarrhythmia, syncope, and sudden cardiac death. Results We here analyze the evolution of the common Gly38Ser variant (rs1805127), using genomic DNAs, complementary DNAs, and HEK293-expressed variants of altogether 19 mammalian species. The between species comparison reveals that the human-specific Gly38Ser polymorphism evolved under strong positive Darwinian selection, probably in adaptation to specific challenges in the fine-…

The Power of Weak Ties: Leveraging Weak Ties in the Evolution of Alliance Networks

2014

In today's knowledge-based economy, the sources of competitive advantage lie more and more in webs of relationships among a variety of firms that over time originate the emergence of interfirm strategic networks. The paper aims to shed light on the role of complex leadership exerted by network central firms in promoting and supporting network interactions and the ensuing processes of knowledge and resource transfer and diffusion. Processes on which the network-based sources of competitive advantage are rooted. In the attempt to make the proposed contribution, on the one hand, we underscore the emergent nature of network interactions stemming from the self-organizing behaviors that spontaneo…

Tour Leaders' Impression Management and Job Performance: Exploring the Moderating Role of Tourists' Self-Monitoring

2012

A tour leader (TL) is a first-line service provider whose performance shapes a tourist's experience and satisfaction during a journey. We examine the moderating effects of the self-monitoring level of group package tour members on the relationship between the use of impression management (IM) tactics by TLs and tourists' subsequent job performance ratings (PRs) of a TL. Data from 485 responses of tourists from 59 outbound tour groups in Taiwan revealed that TLs' use of positive IM tactics – that is, ingratiation, self-promotion, and exemplification – is positively related to tourists' PRs. In contrast, their use of non-positive IM tactics – that is, supplication and intimidation – is negati…

The Power of Smiling. How Politicians’ Displays of Happiness Affect Viewers’ Gaze Behavior and Political Judgments

2019

It is a common assumption that facial expressions of politicians, such as a smile, are powerful tools to draw attention and evoke positive impressions. However, previous research has not fully linked politicians’ nonverbal behavior, viewers’ visual attention and their political impression formation. To address this gap, the research presented in this chapter uses a multi-method design to explore the role of a politician’s smiling for viewers’ judgments about him. More precisely, a laboratory study examined the visual attention (eye-tracking; n = 122) and spontaneous judgments of viewers (continuous response measurement; n = 125) while the participants were exposed to an excerpt of a German …

Protocolo Familiar: sus resultados

2006

L'obiettivo di questo libro è di riferire circa i principali risultati conseguiti da "protocolli familiari". Dopo una breve rassegna della letteratura sugli strumenti di pianificazione strategica nel contesto delle aziende familiari e sull'evoluzione del concetto di protocollo familiare, vengono presentati i risultati di una ricerca condotta in Spagna su un campione di cinquanta imprese familiari estratte fra le circa novanta che hanno redatto un protocollo familiare avvalendosi dell'assistenza professionale di persone direttamente coinvolte nella Cattedra di Family Business dello IESE. Obiettivo della ricerca è di identificare i risultati - positivi o negativi, duraturi o passeggeri - dire…
