Trust in inter-organizational relationships

Trust in inter-organizational collaborative relationships has attracted substantial research interest among academics and practitioners. Previous studies have concentrated on the benefits of trust to business outcomes and economic performance, as it is considered to be a source of competitive advantage. Despite this increased level of interest, there is no consensus, much less overall agreement, about how it should be conceptualized or about the number of dimensions it incorporates. On the inter-organizational level there is an obvious challenge in defining both the trusting party and the objects of trust. Thus, the notion of trust as an under-theorized and poorly understood phenomenon still holds. Hence, the motivation of this study was fuelled by the need to increase our knowledge and understanding of the role and nature of trust in inter-organizational collaborative relationships. It is posited that there is a call for more understanding about its antecedents and consequences, as well as about the very concept in inter-organizational collaborative relationships. The study is divided into two parts. The first part gives a general overview, and the second part comprises four research publications. Both qualitative and quantitative research methodology is utilized. A multi-method research design was used because it provides different levels of data and different perspectives on the phenomenon. The results of this study reveal that trust incorporates three dimensions on both the individual and the organizational level: capability, goodwill, and self-reference. Trust develops from the reputation and behavior of the trusted party. It appears from this study that trust is clearly directed towards both individual boundary spanners and the counterpart company itself – i.e. not only to one or the other. The trusting party, on the other hand, is always an individual, and not the organization per se. Trust increases collaboration benefits and lowers collaboration drawbacks, thus having a positive effect on relationship performance. The major contribution of this study lies in uncovering the critical points and drawbacks in prior research and thereby in responding to the highlighted challenges. The way in which these challenges were addressed offers contributions to three major issues in the emerging theory of trust in the inter-organizational context: firstly, this study clarifies the trustor-trustee discussion; secondly, it conceptualizes trust as existing on both individual and organizational levels; and thirdly, it provides more information about the antecedents of trust and the ways in which it affects relationship performance.

Hückel and Möbius annulenes: relationships between their Hückel-level orbitals and their Hückel-level energies

The problem of convenient access to quantitative Hückel-level descriptions of Möbius and Hückel annulenes for undergraduate lectures about aromaticity is discussed. Frost circle, Zimmerman circle, double circle and Langler semicircular mnemonics are described. The relationship between spectra (complete sets of secular equation roots) for an isoconjugate pair of Hückel and Möbius annulenes and the corresponding acyclic polyene with one less carbon is fully developed. In addition to providing an alternative path to exact spectrum roots, this relationship provides immediate access to almost half of the eigenfunctions for an isoconjugate annulene pair. The remaining eigenfunctions may be obtained very easily.

The lipopolysaccharide of Aeromonas spp: structure-activity relationships

Marine microorganisms, including Aeromonas, are a source of compds. for drug development that have generated great expectations in the last decades. Aeromonas infections produce septicemia, and ulcerative and haemorrhagic diseases in fish. Among the pathogenic factors assocd. with Aeromonas, the lipopolysaccharides (LPS)​, a surface glyconconjugate unique to Gram-​neg. bacteria consisting of lipid A (lipid anchor of the mol.)​, core oligosaccharide and O-​specific polysaccharide (O antigen)​, are key elicitors of innate immune responses. The chem. structure of these three parts has been characterized in Aeromonas. Based on the high variability of repeated units of O-​polysaccharides, a total of 97 O-​serogroups have been described in Aeromonas species, of which four of them (O:11; O:16; O:18 and O:34) account for more than 60​% of the septicemia cases. The core of LPS is subdivided into two regions, the inner (highly conserved) and the outer core. The inner core of Aeromonas LPS is characterized by the presence of 3-​deoxy-​d-​manno-​oct-​2-​ulosonic (ketodeoxyoctonic) acid (Kdo) and l-​glycero-​d-​manno-​Heptoses (l,​d-​Hep)​, which are linked to the outer core, characterized by the presence of Glc, GlcN, Gal, and GalNAc (in Aeromonas salmonicida)​, d,​d-​Hep (in Aeromonas salmonicida)​, and l,​d-​Hep (in Aeromonas hydrophila)​. The biol. relevance of these differences in the distal part of the outer core among these species has not been fully assessed to date. The inner core is attached to the lipid A, a highly conserved structure that confers endotoxic properties to the LPS when the mol. is released in blood from lysed bacteria, thus inducing a major systemic inflammatory response known as septic or endotoxic shock. In Aeromonas salmonicida subsp. salmonicida the Lipid A components contain three major lipid A mols., differing in acylation patterns corresponding to tetra-​, penta- and hexa-​acylated lipid A species and comprising of 4'-​monophosphorylated β-​2-​amino-​2-​deoxy-​d-​glucopyranose-​(1→6)​-​2-​amino-​2-​deoxy-​d-​glucopyranose disaccharide. In the present review, we discuss the structure-​activity relationships of Aeromonas LPS, focusing on its role in bacterial pathogenesis and its possible applications.

Relationships between adolescents and parents values and parents answering behaviour

In this paper we set out a confirmatory factor analysis model relating the values adolescents and their parents aspire to for the child’s future. We approach a problem when collecting parents’ answers and analysing paired data from parents and their child: the fact that in some families only one parent answers, while in others both meet to answer together. In order to account for differences between one-parent and two-parent responses we follow a multiple group structural equation modelling approach. Some significant differences emerged between the two and one answering parent groups. We observed only weak relationships between parents’ and children’s values

Quantitative structure-retention relationships analysis of retention index of essential oils

Genetic algorithm and multiple linear regression (GA-MLR), partial least square (GA-PLS), kernel PLS (GA-KPLS) and Levenberg-Marquardt artificial neural network (L-M ANN) techniques were used to investigate the correlation between retention index (RI) and descriptors for 116 diverse compounds in essential oils of six Stachys species. The correlation coefficient LGO-CV (Q²) between experimental and predicted RI for test set by GA-MLR, GA-PLS, GA-KPLS and L-M ANN was 0.886, 0.912, 0.937 and 0.964, respectively. This is the first research on the QSRR of the essential oil compounds against the RI using the GA-KPLS and L-M ANN.

Anatomical changes on coffee leaves infected by Pseudomonas syringae pv. garcae

ABSTRACTAlthough poorly studied, the bacterial halo blight is an important disease in the major coffee-producing states of Brazil. External damage and anatomical changes on leaves were measured in seedlings of Coffea arabica cv. Mundo Novo, susceptible to Pseudomonas syringae pv. garcae, by using histological sections obtained at 10 and 20 days after inoculation (DAI). The changes on the epidermis were smaller than the lesions measured in the mesophyll, irrespective of the evaluated colonization period, showing that the internal damage caused by the bacterium represent twice the damage observed externally. From the inoculation site, lysis occurred on the epidermal cells and on the palisade and spongy parenchyma cells, with strong staining of their cellular contents, as well as abnormal intercellular spaces in the palisade parenchyma, hypertrophy and hyperplasia of mesophyll cells and partial destruction of chloroplasts. Additionally, this study revealed the presence of inclusion bodies in epidermal and mesophyll cells. Bacterial masses were found in the apoplast between and within mesophyll cells. Bacteria were also observed in the bundle sheath and vascular bundles and were more pronounced at 20 DAI, not only near the inoculation site but also in distant areas, suggesting displacement through the vascular system. These results can be useful to understand this plant-pathogen interaction.

CRM system implementation for managing customer relationships in business-to-business markets

Tutkielman tavoitteena oli selvittää, kuinka CRM-järjestelmä otetaan käyttöön asiakkuuksienhallinnan tueksi yritysten välisillä markkinoilla. Tutkielma keskittyy erityisesti käyttöönoton varhaisiin vaiheisiin selvittämällä, mikä on järjestelmien rooli asiakkuudenhallinnassa ja miten ne tukevat erilaisia käyttäjätasoja, jotka työssä jaettiin strategiseksi, operatiiviseksi ja analyyttiseksi tasoksi. Lisäksi työ esittelee käyttöönottoon yleisimmin liittyviä sudenkuoppia. Tutkielma on laadullinen tutkimus ja siinä on kuvattu CRM-järjestelmän käyttöönottoon liittyviä kysymyksiä yritysten välisillä markkinoilla toimivan caseyrityksen näkökulmasta. Tutkimuksessa havaittiin, että CRM-järjestelmän onnistunut käyttöönotto vaatii mahdollisimman yksinkertaista ja helppokäyttöistä järjestelmää. Käyttöönoton ei myöskään tulisi vaatia monimutkaista koulutusta, vaikkakin koulutusten tärkeys tunnistettiin. Tutkimus osoitti, että vaikka tämänhetkiset CRM-järjestelmät keskittyvät enemmän yksityiskohtaisten asiakasanalyysien tekoon, järjestelmä voi myös palvella asiakkaisiin liittyvän tiedon yhteisenä tallennus- ja jakamispaikkana. Lisäksi tutkimuksessa todettiin, että useimmiten potentiaaliset sudenkuopat olivat luonteeltaan hyvin käytännönläheisiä, kuten järjestelmän käyttämättömyys sekä huono motivointi ja sitouttaminen.

Relationships and estimates of longitudinal growth stress in Eucalyptus dunnii at different ages

The objective of this study was to obtain estimates of longitudinal growth stresses in standing trees of the Eucalyptus dunnii Maiden at eight, thirteen, fifteen and nineteen years of age and to determine their relationships with wood characteristics. The longitudinal growth stresses were indirectly measured by the "CIRAD-Forêt" method and estimated from both the dynamic modulus of elasticity and the modulus of elasticity in tension parallel to the grain. The longitudinal residual strain (LRS) and the estimates of the longitudinal growth stresses tended to increase with the age of the material. The LRS correlated positively and significantly with all the growth stresses estimates. The largestes magnitudes were at 13, 15 and 19 years of age. The basic density presented high, positive and significant correlations with the dynamic modulus of elasticity, estimated in the longitudinal direction, for wood saturated and at 12% moisture content, for all the ages assessed. All the growth stresses estimates presented high, positive and significant correlations between themselves.

SOIL ORGANIC CARBON, CARBON STOCK AND THEIR RELATIONSHIPS TO PHYSICAL ATTRIBUTES UNDER FOREST SOILS IN CENTRAL AMAZONIA

ABSTRACT The soil carbon under Amazonian forests has an important roles in global changing, making information on the soil content and depths of these stocks are considerable interest in efforts to quantify soil carbon emissions to the atmosphere.This study quantified the content and soil organic carbon stock under primary forest up to 2 m depth, at different topographic positions, at Cuieiras Biological Reserve, Manaus/ ZF2, km 34, in the Central Amazon, evaluating the soil attributes that may influence the permanence of soil carbon. Soil samples were collected along a transect of 850 m on topographic gradient Oxisol (plateau), Ultisol (slope) and Spodosol (valley). The stocks of soil carbon were obtained by multiplying the carbon content, soil bulk density and trickiness of soil layers. The watershed was delimited by using STRM and IKONOS images and the carbon contend obtained in the transects was extrapolated as a way to evaluate the potential for carbon stocks in an area of 2678.68 ha. The total SOC was greater in Oxisol followed by Spodosol and Ultisol. It was found direct correlations between the SOC and soil physical attributes. Among the clay soils (Oxisol and Ultisol), the largest stocks of carbon were observed in Oxisol at both the transect (90 to 175.5 Mg C ha-1) as the level of watershed (100.2 to 195.2 Mg C ha-1). The carbon stocks under sandy soil (Spodosol) was greater to clay soils along the transect (160-241 Mg C ha-1) and near them in the Watershed (96.90 to 146.01 Mg C ha-1).

Activation of supply relationships : a study of main providers in the Turku logistics cluster

Företag inom industri och handel väljer allt oftare att låta ett logistikföretag sköta stora delar av sina logistiska processer. Logistikföretagen i sin tur överlåter utförandet av enskilda tjänster, som t.ex. olika typer av transport, till olika samarbetspartners inom branschen. I avhandlingen studeras hur logistikföretag går till väga då de väljer vilka av deras samarbetspartners som ska engageras för att delta i utförandet av ett logistiktjänstepaket, en arbetsprocess som här kallas aktivering. Fokus ligger på aktiveringens innehåll och de faktorer som inverkar på hur den går till och vilka samarbetsparter som kommer att engageras. Arbetet bygger på nätverksansatsen för studier av företagsrelationer på industriella marknader. Aktiveringsprocessen uppfattas som en rätt ordinär, rutinmässig verksamhet i företaget, men den kan också förväntas inverka på hur företagets samarbetsnätverk utvecklas över tiden, genom att vissa relationer förstärks medan andra försvagas. I den empi riska undersökningen deltog 29 logistikföretag i Åboregionen som utgående från ett diskussionsunderlag fick berätta om hur de går till väga vid aktivering.
