Individualized consideration, innovative organizational climate and proactive personality as antecedents of change-oriented and altruist organizational citizenship behaviors

El concepto de comportamiento de ciudadanía organizativa (CCO) ha adquirido un creciente interés en la literatura, materializándose en una amplia variedad de estudios teóricos y empíricos. No obstante, se ha señalado la necesidad de profundizar en los antecedentes propios de cada una de las dimensiones que integran dicho constructo, dado que pocos autores se han centrado en esos aspectos (Podsakoff et al., 2000). En consecuencia, el presente estudio pretende analizar la consideración individualizada del liderazgo transformacional, el clima organizativo innovador y la personalidad proactiva del individuo como posibles antecedentes de dos de las dimensiones que integran los comportamientos de ciudadanía organizativa: los comportamientos orientados al cambio y los altruistas, en base a una revisión y extensión de los principales estudios que han abarcado dichos constructos. En este sentido, se desarrolla un modelo conceptual cuyo objetivo es profundizar sobre estos antecedentes para que investigaciones futuras puedan probar desde un punto de vista empírico, las proposiciones señaladas utilizando métodos cuantitativos o cualitativos.The concept of organizational citizen behaviour (OCB) has grown in popularity in the literature, and has received a great deal of theoretical and empirical study. However, various authors have emphasized the need of gaining a greater understanding of the antecedents of each dimension that makes up this construct, as few authors have focused on these aspects (Podsakoff et al., 2000). Hence, this study aims at analyzing the individualized consideration of leadership, the innovative organizational climate and the proactive personality, as possible antecedents of change-oriented and altruist organizational citizenship behaviors, by means of a revision and extension of the main studies that have dealt with such constructs. In this sense, the present study develops various propositions, derived from a conceptual model, whose aim is to advance the understanding related with OCB antecedents, so that future research can test them from an empirical point of view, using qualitative or quantitative methods.Peer Reviewe

Theoretical analysis of the antecedents and the consequences of students’ identification with their university and their perception of quality

Objecte: L'objectiu d’aquest article és desenvolupar un model conceptual centrat en els antecedents de la identificació de l'alumnat amb la universitat i la seva percepció de la qualitat universitària, perquè investigacions futures puguin provar des d’un punt de vista empíric les proposicions assenyalades. Disseny/metodologia: La metodologia consisteix en una anàlisi de la literatura empírica existent i del models teòrics actuals enfocats en el màrqueting a nivell universitari. Resultats: La identificació de l’estudiant amb la universitat i la seva percepció de qualitat de la institució són dos variables claus per a la captació i la retenció de l’alumnat. Aquest article proposa que la identificació depèn del suport institucional percebut per l'estudiant, que al seu torn està positivament relacionat amb: la comunicació corporativa, la relació universitat-alumne i la relació alumne-alumne. D’altra banda, l’ocupabilitat d’una institució educativa és relaciona positivament amb la percepció de qualitat universitària per part de l’estudiant i aquesta percepció ve determinada per la bona reputació de la universitat i per la percepció de l’estudiant que la universitat fomenta l’ocupabilitat en la seva formació. Limitacions: El model presentat es fonamenta des d’un punt de vista teòric i per tant és un punt de partida de línies futures de caràcter empíric. Implicacions pràctiques: Aquest article teòric pretén donar un punt de sortida i nou enfocament al màrqueting universitari. Esperem que aquest article ajudi a accelerar el progrés en l’àmbit del màrqueting universitari, posant de relleu qüestions fonamentals que necessiten investigació futura. Implicacions socials: La confirmació del model conceptual donaria les eines necessàries perquè les universitats desenvolupin les seves estratègies de captació i retenció d'estudiants basant-se en el màrqueting i en la segmentació, fet que també es relaciona amb un millor servei per part de les universitats publiques i una major satisfacció de l’alumnat. Valor afegit: La principal contribució teòrica es la de proposar incorporar variables clàssicament estudiades en el comportament organitzatiu com antecedent de les variables típicament estudiades en el comportament del consumidor. Purpose: This paper is aimed at developing a conceptual model centered on the antecedents of students’ identification with their university and their perception of the institution’s quality. Design/methodology/approach: This model is based on the analysis of the existing empirical literature and theoretical models focused on marketing at university level. Findings: Students’ identification with their university and the perceived quality of the institution are two key variables for attracting and retaining students. This paper proposes that identification depends on the institutional support received by the student, which in turn is positively related to: corporate communication, the university- student relationship and the student-student relationship. Moreover, the employability is positively related to the perceived quality of the university and this perception is determined by the university reputation and students’ perception that the university encourages employability in their training. Research limitations/implications: This model is informed from a theoretical perspective and therefore it constitutes a starting point for future empirical studies. Practical implications: The present study aims to provide new approaches to university marketing. We hope that this paper will help accelerate progress in the field of university marketing, by emphasizing fundamental issues that deserve future research. Social implications: The confirmation of this conceptual model would provide the necessary tools for universities to develop their strategies of student recruitment and retention based on marketing and segmentation. This can lead to a better service delivered by public universities and a higher student satisfaction. Originality/value: The main theoretical contribution is to include the variables traditionally studied as antecedents in organizational behavior in the variables typically studied in consumer behavior.Peer Reviewe

Bias-induced conformational switching of supramolecular networks of trimesic acid at the solid-liquid interface

Using the tip of a scanning tunneling microscope, an electric field-induced reversible phase transition between two planar porous structures ("chickenwire" and "flower") of trimesic acid was accomplished at the nonanoic acid/highly oriented pyrolytic graphite interface. The chicken wire structure was exclusively observed for negative sample bias, while for positive sample bias only the more densely packed flower structure was found. We suggest that the slightly negatively charged carboxyl groups of the trimesic acid molecule are the determining factor for this observation: their adsorption behavior varies with the sample bias and is thus responsible for the switching behavior.

Comparing Cyanophenyl and Pyridyl Ligands in the Formation of Porphyrin-Based Metal−Organic Coordination Networks

In recent studies, porphyrin derivatives have been frequently used as building blocks for the fabrication of metal–organic coordination networks (MOCNs) on metal surfaces under ultrahigh vacuum conditions (UHV). The porphyrin core can host a variety of 3d transition metals, which are usually incorporated in solution. However, the replacement of a pre-existing metal atom in the porphyrin core by a different metallic species has been rarely reported under UHV. Herein, we studied the influence of cyanophenyl and pyridyl functional endgroups in the self-assembly of structurally different porphyrin-based MOCNs by the deposition of Fe atoms on tetracyanophenyl (Co-TCNPP) and tetrapyridyl-functionalized (Zn-TPPyP) porphyrins on Au(111) by means of scanning tunneling microscopy (STM). A comparative analysis of the influence of the cyano and pyridyl endgroups on the formation of different in-plane coordination motifs is performed. Each porphyrin derivative formed two structurally different Fe-coordinated MOCNs stabilized by three- and fourfold in-plane coordination nodes, respectively. Interestingly, the codeposited Fe atoms did not only bind to the functional endgroups but also reacted with the porphyrin core of the Zn-substituted porphyrin (Zn-TPyP), i.e., an atom exchange reaction took place in the porphyrin core where the codeposited Fe atoms replaced the Zn atoms. This was evidenced by the appearance of molecules with an enhanced (centered) STM contrast compared with the appearance of Zn-TPyP, which suggested the formation of a new molecular species, i.e., Fe-TPPyP. Furthermore, the porphyrin core of the Co-substituted porphyrin (Co-TCNPP) displayed an off-centered STM contrast after the deposition of Fe atoms, which was attributed to the binding of the Fe atoms on the top site of the Co-substituted porphyrin core. In summary, the deposition of metal atoms onto organic layers can steer the formation of structurally different MOCNs and may replace pre-existing metal atoms contained in the porphyrin core
