The quality-value-satisfaction-loyalty chain: relationships and impacts

Purpose – The purpose of this paper is to explore the classical topics of services literature in a tourism experience with a means‐end‐model on the quality‐value‐satisfaction‐loyalty chain. Within this wide stream of research, this work has a particular interest on value antecedents and on the sense of the link between value and satisfaction.Design/methodology/approach – An overall tourism experience with positive and negative antecedents (benefits and sacrifices experienced) and classical evaluations (perceived value, satisfaction and loyalty as behavioral intention) is analyzed through two competing structural models measured with partial least squares on a sample of 274 students traveling in groups for leisure purposes.Findings – The empirical findings show that: the chain of constructs service quality‐perceived value‐customer satisfaction‐loyalty is once again confirmed in a service setting; affective antecedents (social value, play and aesthetics) are more important determinants of perceived value an.
The integrated global temperature change potential (iGTP) and relationships between emission metrics

The Kyoto Protocol compares greenhouse gas emissions (GHGs) using the global warming potential (GWP) with a 100 yr time-horizon. The GWP was developed, however, to illustrate the difficulties in comparing GHGs. In response, there have been many critiques of the GWP and several alternative emission metrics have been proposed. To date, there has been little focus on understanding the linkages between, and interpretations of, different emission metrics. We use an energy balance model to mathematically link the absolute GWP, absolute global temperature change potential (AGTP), absolute ocean heat perturbation (AOHP), and integrated AGTP. For pulse emissions, energy conservation requires that AOHP = AGWP − iAGTP/λ and hence AGWP and iAGTP are closely linked and converge as AOHP decays to zero. When normalizing the metrics with CO2 (GWP, GTP, and iGTP), we find that the iGTP and GWP are similar numerically for a wide range of GHGs and time-horizons, except for very short-lived species. The similarity between the iGTPX and GWPX depends on how well a pulse emission of CO2 can substitute for a pulse emission of X across a range of time-horizons. The ultimate choice of emission metric(s) and time-horizon(s) depends on policy objectives. To the extent that limiting integrated temperature change over a specific time-horizon is consistent with the broader objectives of climate policy, our analysis suggests that the GWP represents a relatively robust, transparent and policy-relevant emission metric.
Career success for international professional women in the land of the equal? Evidence from Norway

This study investigates the career success of international expatriate women in Norway. Norwegian and international women were compared on both objective and subjective career success. Participants were 125 Norwegian women and 168 international expatriate women who answered a 58 item questionnaire. Although Norwegian women achieved higher career success than the expatriate group, these effects disappeared for objective career success when expatriate women had a high level of education, high English language competency and motivation. Motivation, self focused conflict resolution and language competency were positively associated with subjective career success. Results suggest that although being foreign can be a disadvantage in Norway, expatriate women can overcome this liability through investment in education, language and motivation. Implications for international expatriate women are discussed.
Human resource management: when research confronts theory

Research exploring the relationship between human resource management (HRM) and outcomes such as corporate performance encounters a range of significant practical difficulties. Using two surveys as illustrative cases, this paper examines the practical challenges of operationalizing and measuring HRM, measuring the various outcomes and assessing the relationship between HRM and corporate performance. Despite the problems, it is suggested that significant progress has been made. While possible solutions to some of the problems are put forward, it is argued that a key requirement remains more clearly specified theory, particularly theory about the nature of HRM.
An Evaluation of Document Keyphrase Sets

Keywords and keyphrases have many useful roles as document surrogates and descriptors, but the manual production of keyphrase metadata for large digital library collections is at best expensive and time-consuming, and at worst logistically impossible. Algorithms for keyphrase extraction like Kea and Extractor produce a set of phrases that are associated with a document. Though these sets are often utilized as a group, keyphrase extraction is usually evaluated by measuring the quality of individual keyphrases. This paper reports an assessment that asks human assessors to rate entire sets of keyphrases produced by Kea, Extractor and document authors. The results provide further evidence that human assessors rate all three sources highly (with some caveats), but show that the relationship between the quality of the phrases in a set and the set as a whole is not always simple. Choosing the best individual phrases will not necessarily produce the best set; combinations of lesser phrases may result in better overall quality.
Dutch Logistics Service Providers and Sustainable Physical Distribution: Searching for Focus

As environmental concerns becoming increasingly important to logistics service providers, the question arises as to how they can achieve sustainable physical distribution practices while surviving the severe competition in freight transport. This issue is further complicated by the pressures from the many different shippers involved, public expectations and regulating authorities. Therefore, achieving sustainable physical distribution is definitely a wicked problem. In order to understand how logistics service providers attempt to tackle these problems, a research study was conducted amongst logistics service providers who are frontrunners in implementing sustainability practices and who participate in the Lean and Green program, to promote sustainability within the logistic chain in the Netherlands. Companies willing to participate in this award scheme, must achieve the goal of reducing their CO2 production by 20% within a 5-year-period. The transport market is very competitive and sustainability is just one of the many logistical concerns that service providers must solve. Our research shows that the logistics service providers participating in the Lean and Green scheme preferred solutions which involved cooperative strategies over – third-parties solutions.
Pressure-flow specificity of inspiratory muscle training.

The inspiratory muscles (IM) can be trained by having a subject breathe through inspiratory resistive loads or by use of unloaded hyperpnea. These disparate training protocols are characterized by high inspiratory pressure (force) or high inspiratory flow (velocity), respectively. We tested the hypothesis that the posttraining improvements in IM pressure or flow performance are specific to training protocols in a way that is similar to force-velocity specificity of skeletal muscle training. IM training was accomplished in 15 normal subjects by use of three protocols: high inspiratory pressure-no flow (group A, n = 5), low inspiratory pressure-high flow (group B, n = 5), and intermediate inspiratory pressure and flow (group C, n = 5). A control group (n = 4) did no training. Before and after training, we measured esophageal pressure (Pes) and inspiratory flow (VI) during single maximal inspiratory efforts against a range of external resistances including an occluded airway. Efforts originated below relaxation volume (Vrel), and peak Pes and VI were measured at Vrel. Isovolume maximal Pes-VI plots were constructed to assess maximal inspiratory pressure-flow performance. Group A (pressure training) performed 30 maximal static inspiratory maneuvers at Vrel daily, group B (flow training) performed 30 sets of three maximal inspiratory maneuvers with no added external resistance daily, and group C (intermediate training) performed 30 maximal inspiratory efforts on a midrange external resistance (7 mm ID) daily. Subjects trained 5 days/wk for 6 wk. Data analysis included comparison of posttraining Pes-VI slopes among training groups. (ABSTRACT TRUNCATED AT 250 WORDS)
Stabilization Activities by Underwriters after Initial Public Offerings

Prior research has assumed that underwriters post a stabilizing bid in the aftermarket. We find instead that aftermarket activities are less transparent and include stimulating demand through short covering and restricting supply by penalizing the f lipping of shares. In more than half of IPOs, a short position of an average 10.75 percent of shares offered is covered in 22 transactions over 16.6 days in the aftermarket, resulting in a loss of 3.61 percent of underwriting fees. Underwriters manage price support activities by using a combination of aftermarket short covering, penalty bids, and the selective use of the overallotment option. RESEARCHERS ARE STILL TRYING TO UNDERSTAND the price behavior of initial public offerings ~IPOs! 1 Short-run underpricing and long-run overpricing continue to be a puzzle. Underpricing refers to the initial trading of IPOs above the offer price in the immediate aftermarket, whereas overpricing refers to long-run underperformance. However, finance research has paid little attention to the specific activities of underwriters in the aftermarket that are likely to have an impact on IPO price performance. These interventions by underwriters are not well understood because of both lack of data and lack of transparency in industry practices. The unique data set used in this paper allows for the first time a comprehensive analysis of exactly how these aftermarket activities are conducted, the characteristics of IPOs in which un

Enhancement of Carotenoid Biosynthesis in Transplastomic Tomatoes by Induced Lycopene-to-Provitamin A Conversion1[OA]

Carotenoids are essential pigments of the photosynthetic apparatus and an indispensable component of the human diet. In addition to being potent antioxidants, they also provide the vitamin A precursor β-carotene. In tomato (Solanum lycopersicum) fruits, carotenoids accumulate in specialized plastids, the chromoplasts. How the carotenoid biosynthetic pathway is regulated and what limits total carotenoid accumulation in fruit chromoplasts is not well understood. Here, we have introduced the lycopene β-cyclase genes from the eubacterium Erwinia herbicola and the higher plant daffodil (Narcissus pseudonarcissus) into the tomato plastid genome. While expression of the bacterial enzyme did not strongly alter carotenoid composition, expression of the plant enzyme efficiently converted lycopene, the major storage carotenoid of the tomato fruit, into provitamin A (β-carotene). In green leaves of the transplastomic tomato plants, more lycopene was channeled into the β-branch of carotenoid biosynthesis, resulting in increased accumulation of xanthophyll cycle pigments and correspondingly reduced accumulation of the α-branch xanthophyll lutein. In fruits, most of the lycopene was converted into β-carotene with provitamin A levels reaching 1 mg per g dry weight. Unexpectedly, transplastomic tomatoes also showed a >50% increase in total carotenoid accumulation, indicating that lycopene β-cyclase expression enhanced the flux through the pathway in chromoplasts. Our results provide new insights into the regulation of carotenoid biosynthesis and demonstrate the potential of plastids genome engineering for the nutritional enhancement of food crops.
Heterogeneous Investors' Reaction to Exchange Rate Movements: New Evidence from a Unique Emerging Market

Previous studies find mixed results on the relation between exchange rate movements and stock returns. We revisit the issue by exploring the effect of market efficiency and heterogeneous investors' reaction to exchange rate changes using the unique event of Chinese currency appreciation. Our results show that different investor groups react differently to exchange rate appreciation. In addition, we find that investors with limited investment opportunities react more positively to exchange rate appreciation. Our results suggest that the issues of market efficiency and the differences among investors are important factors to consider when one analyzes the relation between exchange rate movements and stock returns.
Do age and extended culture affect the architecture of the zona pellucida of human oocytes and embryos?

Advanced female age and extended in vitro culture have both been implicated in zona pellucida (ZP) hardening and thickening. This study aimed to determine the influence of (i) the woman's age and (ii) prolonged in vitro culture of embryos on ZP thickness and density using non-invasive polarized light (LC-PolScope) microscopy. ZP thickness and density (measured as retardance) were determined in oocytes, embryos and blastocysts in women undergoing intracytoplasmic sperm injection (ICSI) in two age groups (older, >38 years; younger, ≤38 years). A total of 193 oocytes from 29 patients were studied. The younger group contained 100 oocytes and the older group 93 oocytes. The ZP was significantly thicker in metaphase II oocytes in the older group compared with the younger group (mean ± SD: 24.1 ± 2.5 μm vs 23.1 ± 3.3 μm; p = 0.01) but ZP density was equal (2.8 ± 0.7 nm). By day 2 of culture, embryos from the two groups had similar ZP thickness (22.2 ± 2.2 μm vs 21.7 ± 1.6 μm; p = 0.28) and density (2.9 ± 0.7 nm vs 2.8 ± 0.8 nm; p = 0.57). For the embryos cultured to blastocyst (older: n = 20; younger: n = 18) ZP thickness was similar in the two groups (19.2 ± 2.7 μm vs 19.1 ± 5.0 μm; p = 0.8) but thinner than on day 2. The older group had significantly denser ZP than the younger group (4.2 ± 0.5 nm vs 3.3 ± 1.0 nm, p < 0.01). Blastocysts from both groups had significantly denser ZP than their corresponding day 2 embryos (older: 4.2 ± 0.5 nm vs 2.9 ± 0.7 nm, p < 0.001; younger: 3.3 ± 1.0 nm vs 2.8 ± 0.8 nm, p = 0.013). It is concluded that there is little relationship between ZP thickness and its density as measured by polarized light microscopy. While ZP thickness decreases with extended embryo culturing, the density of the ZP increases. ZP density increases in both age groups with extended culture and, interestingly, more in embryos from older compared with younger women.
The Nobel Memorial Prize for Daniel Kahneman

In an essay on his web page, Paul Krugman recommends as his first rule of research to young economists that they "Listen to the Gentiles. Pay attention to what intelligent people are saying, even if they do not have your customs or speak your analytical language. " His own context for applying this principle was in understanding that international-trade economists should pay attention to the field of geography: "Geographers and regional scientists have amassed a great deal of evidence on the nature and importance of localized external economies, and organized that evidence intelligently if not rigorously. " To urge an academic discipline to listen to its critics, and to embrace the insights of another discipline even when the language and conceptual differences between the disciplines invite dismissal, is excellent advice. It is rarely followed. But it is even rarer for critics from one discipline to persistently and intelligently insinuate themselves into another discipline by making an effort to use a common language and to minimize conceptual differences. Yet this is what two brilliant psychologists, Daniel Kahneman and Amos Tversky, have done since the early 1970s. It is surely one of the biggest boons to the social sciences in recent decades that they have launched this research program so relevant for economics, doing so with an ability and willingness to address economists in economic language and venues, and with an emphasis on the implications of their research for economic questions. In recognition of these contributions, Daniel Kahneman was awarded The Bank of Sweden Prize in Economic Science in Memory of Alfred Nobel in October 2002. '
Venture capital availability and labour market performance around the world

This article studies the effects of venture capital on the performance of the labour market. Using data from a much larger sample of countries than previous papers, it finds more readily available venture capital to favourably affect both the unemployment and the employment rate. The magnitude of the estimated effects is substantial. We control for both endogeneity of venture capital availability and most major determinants of labour market performance. The results are robust to variations in specification.
Correlation of p 53 and the Proto-Oncogene eIF 4 E in Larynx Cancers : Prognostic Implications 1

p53 abnormalities constitute the most frequent genetic alterations identified in larynx cancers. p53 overexpression in histologically “tumor-free” surgical margins correlates with a high recurrence rate. However, only 50–60% of tumors overexpressp53. The tumor marker eIF4E is overexpressed in 100% of larynx cancers, and overexpression of eIF4E in histologically “tumor-free” margins predicts a significantly higher recurrence. We undertook this study to correlate the expression ofp53 and eIF4E in the tumors and surgical margins of squamous cell cancers of the larynx and to determine their prognostic value. A retrospective analysis was performed on 54 patients who underwent surgery for squamous cell cancers of the larynx. Patient and tumor characteristics were reviewed, and the time to recurrence was noted. Paraffin-embedded sections from the tumors and surgical margins were immunostained with antibodies toeIF4E and p53, and a qualitative analysis was performed. All 54 patients (100%) overexpressed eIF4E in the primary tumor, whereas 25 of 53 patients (47%) werep53 positive. Thirtytwo of the 54 patients (59%) hadeIF4E-positive margins. All 6 of 53 patients (11%) with p53-positive margins also overexpressed eIF4E in the margins. There was a significant correlation betweenp53and eIF4E being positive in the margins (Spearman’s correlation coefficient,P 5 0.03). Twenty-one of the 25 patients (84%) that recurred, including the 6 patients with p53-positive margins, hadeIF4E-positive margins. Hence, although the univariate analysis showed that nodal status and botheIF4E and p53 expression in the margins were significant predictors of recurrence (P < 0.05), in the multivariate analyses only nodal status ( P < 0.001) and eIF4E in the margins (P < 0.001) were significant predictors of recurrence. Kaplan-Meier analysis demonstrated that the disease-free intervals for eIF4E-positive margins were significantly shorter than eIF4E-negative margins (P 5 0.0007). There was no additional effect to the combination of positive p53 and eIF4E margins (P 5 0.21). The overexpression of eIF4E in the margins appears to be a more sensitive indicator of recurrence and may be an earlier event in the process of tumorigenesis thanp53.
The Endoplasmic Reticulum Membrane J Protein C18 Executes a Distinct Role in Promoting Simian Virus 40 Membrane Penetration

ABSTRACT The nonenveloped simian virus 40 (SV40) hijacks the three endoplasmic reticulum (ER) membrane-bound J proteins B12, B14, and C18 to escape from the ER into the cytosol en route to successful infection. How C18 controls SV40 ER-to-cytosol membrane penetration is the least understood of these processes. We previously found that SV40 triggers B12 and B14 to reorganize into discrete puncta in the ER membrane called foci, structures postulated to represent the cytosol entry site (C. P. Walczak, M. S. Ravindran, T. Inoue, and B. Tsai, PLoS Pathog 10:e1004007, 2014). We now find that SV40 also recruits C18 to the virus-induced B12/B14 foci. Importantly, the C18 foci harbor membrane penetration-competent SV40, further implicating this structure as the membrane penetration site. Consistent with this, a mutant SV40 that cannot penetrate the ER membrane and promote infection fails to induce C18 foci. C18 also regulates the recruitment of B12/B14 into the foci. In contrast to B14, C18's cytosolic Hsc70-binding J domain, but not the lumenal domain, is essential for its targeting to the foci; this J domain likewise is necessary to support SV40 infection. Knockdown-rescue experiments reveal that C18 executes a role that is not redundant with those of B12/B14 during SV40 infection. Collectively, our data illuminate C18's contribution to SV40 ER membrane penetration, strengthening the idea that SV40-triggered foci are critical for cytosol entry. IMPORTANCE Polyomaviruses (PyVs) cause devastating human diseases, particularly in immunocompromised patients. As this virus family continues to be a significant human pathogen, clarifying the molecular basis of their cellular entry pathway remains a high priority. To infect cells, PyV traffics from the cell surface to the ER, where it penetrates the ER membrane to reach the cytosol. In the cytosol, the virus moves to the nucleus to cause infection. ER-to-cytosol membrane penetration is a critical yet mysterious infection step. In this study, we clarify the role of an ER membrane protein called C18 in mobilizing the simian PyV SV40, a PyV archetype, from the ER into the cytosol. Our findings also support the hypothesis that SV40 induces the formation of punctate structures in the ER membrane, called foci, that serve as the portal for cytosol entry of the virus.
A Model of Investment Under Uncertainty: Modern Irrigation Technology and Emerging Markets in Water

This article develops a stochastic dynamic model of irrigation technology adoption. It predicts that farms will not invest in modern technologies unless the expected present value of investment exceeds the cost by a potentially large hurdle rate. The article also demonstrates that, contrary to common belief, water markets can delay adoption. The introduction of a market should induce farms with abundant (scarce) water supplies to adopt earlier (later) than they would otherwise. This article was motivated by evidence that, contrary to NPV predictions, farms wait until random events such as drought drive returns significantly above costs before investing in modern irrigation technologies.
