Mujeres directivas, espacio de poder y relaciones de género

2003

This study has two main aims, both of which are related to gender segregation in the labour market and to the "glass ceiling phenomen on". The first is to establish why women with high educational qualifications and management capabilities tend not to reach the top of the organisational pyramid. The second is to investigate whether traditional management models, that is, masculine models, are able to respond effectively to the challenges of the current labour situation. To answer these two questions we will study the obstacles that women encounter in their attempts to build professional careers, and will also analyse gender diversity and the transformational management style. The starting p…

In vitro modeling of the ternary interaction in juvenile hormone metabolism

1996

The gradual decline in juvenile hormone (JH) titer followed by its complete clearance early in the last larval instar is required for the onset of the metamorphosis of lepidopterous larvae. JH titer is regulated by both biosynthesis and degradation. Two major pathways for JH metabolism, ester hydrolysis and epoxide hydration, are due to JH esterase (JHE) and JH epoxide hydrolase (JHEH), respectively. In vitro experiments designed to elucidate the molecular mechanism of JH metabolism are described. First, microsomal JHEH in Manduca sexta eggs was identified by using photoaffinity analogs of JH, and purified to homogeneity with ion exchange and hydroxylapatite columns. Purified JHEH from M. s…

Purification and reassessment of ligand binding by the recombinant, putative juvenile hormone receptor of the tobacco hornworm, Manduca sexta

1996

The 29 kDa protein from the larval epidermis of the tobacco hornworm, Manduca sexta, that specifically bound photoaffinity analogs of JH I and JH II was produced by a recombinant baculovirus (rJP29). The higher of the two molecular weight forms made corresponded to a protein that could be formed by read‐through of the TGA termination codon to the following TAA. The previously reported, apparent high affinity binding of [methyl‐3H]‐JH I by rJP29 as measured by the dextran‐coated charcoal (DCC) assay [Palli et al., Proc Natl Acad Sci USA 91:6191–6195 (1994)] was found to be artifactual due to endogenous cellular esterases that co‐purified with rJP29 through both DEAE cellulose and MonoQ chrom…

Evaluation of web browsing experience by people with cognitive disability

2012

After a review of research in last 10 years we have seen the low output of work on the usability of the web, with respect to users with cognitive disabilities. This time we intend to explore the problems faced with mild or moderate intellectual disabilities when using the World Wide Web. We conducted a study to assess the Web site navigation experience using the Usability Lab of Access Research Unit, University of Valencia, where we recorded and analyzed the Web-user interaction using the technique of Thought Manifesto and Interview, from a qualitative methodological approach, to thereby detect the problems they have when surfing the Web sites for people with cognitive deficits.

Minding the Gaps : The Role of Finnish Civil Society Organizations in the Labour Market Integration of Migrants

2021

AbstractThe growing role of civil society organizations (CSOs) in welfare service provision is sometimes portrayed as a threat to welfare state universalism in Nordic societies. In Finland, CSOs co-produce integration services alongside comprehensive official integration programmes, compensating for gaps and shortcomings in those services. We identify three “gaps”, which are (1) limited availability of services in terms of time and target group, (2) lack of direct labour market contacts and (3) limited flexibility to serve individual needs. We assess how CSOs target these gaps with their service offerings through qualitative interviews with policy implementers, CSO workers and migrants. How…

Consumer perceptions of product packaging

2006

Purpose – This paper seeks to discuss the need to understand consumer perceptions in order to correctly design product packing and to achieve the desired position in the minds of consumers.Design/methodology/approach – Data collection was divided into two phases. The first, (based on designers' opinions), to determine the key graphic variables in the design of packaging. The second, (based on consumers' opinions), to associate each packaging with a positioning strategy. The seven product‐positioning strategies selected were represented from the consumers' standpoint using multidimensional scaling. Four maps were obtained related to: alternative packaging colours; alternative packaging typog…

eWOM on Travel Agency Selection: Specialized versus Private Label

2016

In the travel industry, electronic word of mouth (eWOM) elicits a major influence on consumers’ decision making. Travel retailers are facing the new challenges derived from the different nature of their competitors—big hypermarkets, for instance, are extending their brands to travel services—and the challenges derived from online comments that consumers have access to. With a sample of 263 tourists, and using a fuzzy-set qualitative comparative analysis data analysis, this paper shows how the selection between a specialized travel agency and a private label (PL) agency is influenced by five factors: the usefulness attached to online reviews by users and the valence of those online reviews, …

Relationship marketing management: Its importance in private label extension

2014

article Trust Commitment Experience Loyalty Relationship marketing aims to generate long-term profitable relationships between partners. In the context of the convenience goods market, the present study considers private labels in traditional categories as a tool to develop effective relationships. The main contribution of the study is the use of the relationship approach to explain private label loyalty and the success of store brand extension strategies. Drawing upon a sample of 434 individual and using EQS software, this study shows that customer experience, satisfaction, trust, and commit- ment to private labels play an important role in customer loyalty toward private labels in conveni…

Contract Renewal in Urban Water Services, Incumbent Advantage, and Market Concentration

2020

Contract renewal with the incumbent is common practice in the contracting-out of public services. It could, however, affect competition by reinforcing trends towards market concentration. This article contributes empirical evidence on the determinants of the result of public tenders for the renewal of private provision of the urban water service. A dataset with information on 215 public tenders held in Spain between 2008 and 2019 is employed. The methodology is grounded in logistic regression techniques. The findings indicate that incumbents' size does not play a role in the proba-bility of alternating between service providers. Furthermore, competition−proxied by the number of bidders−and …
