Market information approaches, product innovativeness, and firm performance: An empirical study in the fashion industry     

Paola Cillo  Luigi M. De Luca  Gabriele Troilo 《Research Policy》2010,39(9):1242-1252

In this study the authors propose a distinction between two approaches to market information, rooted in the marked-based learning theory. The two approaches are conceptualized and operationalized on the basis of their differences along three processes: generation, dissemination and use of market information. In the retrospective approach, the generation process is based on expressed customer needs and extant market relations; the dissemination is based on formal mechanisms; the use process is more instrumental. In the forward-looking approach, the generation process is based on latent customer needs and on the evolutionary patterns of the future market relations; the dissemination process is more informal; the use of information is more conceptual. A series of hypotheses concerning the relationships between these approaches, product innovativeness and firm performance are tested on a sample of Italian fashion firms. Results suggest that the two approaches are complementary for firm performance, but have opposite effects on product innovativeness: while a forward-looking approach is positively related to product innovativeness, a retrospective approach seems to be negatively related. The results also shed light on how market information approaches and product innovativeness jointly affect firm performance.  相似文献   

Parental satisfaction with disabled children’s school inclusion in Italy     

Mirella Zanobini  Paola Viterbori  Valentina Garello  Roberta Camba 《欧洲特需教育杂志》2018,33(5):597-614

The principal aim of the present study is to examine the level of parental satisfaction with inclusive education for their children with disability attending Italian schools of any grade level. The survey involved 285 parents of pupils randomly selected from the population of students with disability certificates. On average, parents expressed a high level of satisfaction. Four principal components of parental satisfaction were extracted from the item scores of the questionnaire: inclusive educational practices; environment and special equipment; classmates’ and families’ acceptance; integration between education and rehabilitation activities. Various correlations were found between these aspects and both child-related and context-related variables. In particular, children’s emotional regulation abilities evaluated by teachers are involved in various dimensions of the parents’ satisfaction. On the other hand, satisfaction with the integration between the educational and rehabilitation activities showed a significant negative correlation with the fathers’ and mothers’ educational level. Lastly, parental satisfaction towards classmates’ and families’ acceptance appears to be the most critical aspect and tends to decrease in relation to school level, while it is positively linked with the number of hours the support teacher spends in class. Taken together, these results stimulate useful considerations to promote better practices in inclusive education.  相似文献   

Does it matter where patent citations come from? Inventor vs. examiner citations in European patents     

Paola Criscuolo 《Research Policy》2008,37(10):1892-1908

This paper addresses the question of whether patent citations are useful indicators of technology flows. We exploit the distinction between citations added by inventors and patent examiners. We use information from the search reports of European Patent Office patent examiners to construct our dataset of patenting activity in Europe and the US, and apply various econometric models to investigate what determines the probability that a citation is added by the inventor rather than the examiner. Contrary to previous work which uses US Patent and Trademark Office data, we find that geographical distance is a factor that strongly diminishes the probability of knowledge flows. We find other significant effects of such factors as cognitive distance, time and strategic factors on citing behaviour.  相似文献   

Mechanical power,thrust power and propelling efficiency: relationships with elite sprint swimming performance     

Giorgio Gatta  Ian Swaine  Paola Zamparo 《Journal of sports sciences》2018,36(5):506-512

The purpose of this study was to explore the relationships between mechanical power, thrust power, propelling efficiency and sprint performance in elite swimmers. Mechanical power was measured in 12 elite sprint male swimmers: (1) in the laboratory, by using a whole-body swimming ergometer (W'_TOT) and (2) in the pool, by measuring full tethered swimming force (F_T) and maximal swimming velocity (V_max): W'_T = F_T · V_max. Propelling efficiency (η_P) was estimated based on the “paddle wheel model” at V_max. V_max was 2.17 ± 0.06 m · s^?1, η_P was 0.39 ± 0.02, W'_T was 374 ± 62 W and W'_TOT was 941 ± 92 W. V_max was better related to W'_T (useful power output: R = 0.943, P < 0.001) than to W'_TOT (total power output: R = 0.744, P < 0.01) and this confirms the use of the full tethered test as a valid test to assess power propulsion in sprinters and to estimate swimming performance. The ratio W'_T/W'_TOT (0.40 ± 0.04) represents the fraction of total mechanical power that can be utilised in water (e.g., η_P) and was indeed the same as that estimated based on the “paddle wheel model”; this supports the use of this model to estimate η_P in swimming.  相似文献   

Municipal consultants’ participation in building networks to support science teachers’ work     

Martin Krabbe Sillasen  Paola Valero 《Cultural Studies of Science Education》2013,8(3):595-618

This paper focuses particularly on the role of municipal science consultants in developing and maintaining network activities and connections among primary school science teachers. The hypothesis is that consultants play a crucial role in supporting strategic planning, and sustaining contacts and activities within professional learning networks. The research is framed by a project that involved 80 primary science teachers in 20 schools. The aim of the project was to develop network activities that facilitate sustainable change of the participating schools’ collective culture and practice of science teaching. The authors were involved as researchers and evaluators in the project. Data consist of reports from the consultants about their participation in various network activities, school assessment reports and a longitudinal survey. Three distinct cases are analysed through the use of a framework of professional learning networks to assess the consultants’ opportunities and constraints in terms of participating in network development. The results indicate that the consultants’ roles in successful network formation is characterized by personal stable contacts within the science teacher community in the municipality, availability of municipal resources to support network activities, participation in strategic planning of municipal network support, and facilitation of the development of new teaching activities within schools or in collaboration between schools. These four distinctive features of municipal science consultants’ participation in supporting network activities enable the participants to share and develop teaching activities.  相似文献   

Integrity in UNESCO World Heritage Sites. A comparative study for rural landscapes     

Paola Gullino  Federica Larcher 《Journal of Cultural Heritage》2013,14(5):389-395

Since 2005, Outstanding Universal Value (OUV) is the standard by which United Nations Educational Scientific and Cultural Organization (UNESCO) evaluates world cultural heritage site suitability. The sites worthy of UNESCO preservation as well as the parameters used to demonstrate OUV are diverse. Our study focused on the uniquely distinguished rural landscape sites and the OUV parameter of integrity. Integrity however, is an elusive concept for which UNESCO provides no definitional protocol, and for which the scientific community objects to a static or pure historical interpretation. Given this, our work aims to analyse the concept of integrity and how it can be used to preserve the heritage of rural landscapes. After reviewing the UNESCO approach, we focused on the international scientific debate on the meaning and application of integrity. We designed and conducted a comparative study of UNESCO rural landscapes selected from the 2011 World Heritage List. Documents describing the historical, rural, and agro-ecological features of each of the fourteen rural sites were analysed. From this, several historical and ecological parameters were chosen as “values to have” and several socio-economic and management parameters were chosen as “values to maintain” to assess the integrity of each landscape. Our results found integrity to be a value of both cultural and natural landscapes and that it is key to site identity. We demonstrated that UNESCO assigns a high value to the following parameters: historical features, traditional crops and local products, land-use and agricultural practice permanence, and the presence of architecture related to agricultural activity. Finally, we found the relationship between culture and nature to characterize best the integrity of a rural landscape, rather than nature or culture alone.  相似文献   

Evaluation of sample hemolysis in blood collected by S-Monovette? using vacuum or aspiration mode     

Giuseppe Lippi  Paola Avanzini  Roberta Musa  Franca Sandei  Rosalia Aloe  Gianfranco Cervellin 《Biochemia medica : ?asopis Hrvatskoga dru?tva medicinskih biokemi?ara / HDMB》2013,23(1):64-69

Background:

In vitro hemolysis can be induced by several biological and technical sources, and may be worsened by forced aspiration of blood in vacuum tubes. This study was aimed to compare the probability of hemolysis by drawing blood with a commercial evacuated blood collection tube, and S-Monovette used either in the “vacuum” or “aspiration” mode.

Materials and methods:

The study population consisted in 20 healthy volunteers. A sample was drawn into 4.0 mL BD Vacutainer serum tube from a vein of one upper arm. Two other samples were drawn with a second venipuncture from a vein of the opposite arm, into 4.0 mL S-Monovette serum tubes, by both vacuum an aspiration modes. After separation, serum potassium, lactate dehydrogenase (LD) and hemolysis index (HI) were tested on Beckman Coulter DxC.

Results:

In no case the HI exceed the limit of significant hemolysis. As compared with BD Vacutainer, no significant differences were observed for potassium and LD using S-Monovette with vacuum method. Significant increased values of both parameters were however found in serum collected into BD Vacutainer and S-Monovette by vacuum mode, compared to serum drawn by S-Monovette in aspiration mode. The mean potassium bias was 2.2% versus BD Vacutainer and 2.4% versus S-Monovette in vacuum mode, that of LD was 2.7% versus BD Vacutainer and 2.1% versus S-Monovette in vacuum mode. None of these variations exceeded the allowable total error.

Conclusions:

Although no significant macro-hemolysis was observed with any collection system, the less chance of producing micro-hemolysis by S-Monovette in aspiration mode suggest that this device may be used when a difficult venipuncture combined with the vacuum may increase the probability of spurious hemolysis.  相似文献   

Mechanical properties of the triceps surae: Differences between football and non-football players     

Aurélio Faria  Ronaldo Gabriel  João Abrantes  Paola Wood  Helena Moreira 《Journal of sports sciences》2013,31(14):1559-1567

Abstract

We investigated the mechanical properties of the triceps surae between professional, junior, and non-football players. Fifty-nine men participated in this study. The mechanical properties of the right legs’ triceps surae were measured in vivo using a free oscillation technique; no significant differences existed between the groups. The mean results for musculo-articular stiffness, damping coefficient, and damping ratio were as follows: professional football players (21523 N· m^?1, 330.8 N · s · m^?1, and 0.201); junior football players (21063 N · m^?1, 274.4 N · s · m^?1, and 0.173); and non-players (19457 N · m^?1, 281.5 N · s · m^?1, and 0.184). When analysed according to position, the results were as follows: defender (21447 N · m^?1, 308.6 N · s · m^?1, and 0.189); midfielder (20762 N · m^?1, 250.7 N · s · m^?1, and 0.157); winger (21322 N · m^?1, 335.1 N · s · m^?1, and 0.212); forward (22085 N · m^?1, 416.2 N · s · m^?1, and 0.254); and non-players (19457 N · m^?1, 281.5 N · s · m^?1, and 0.184).

Thus, football training, football games, and the position played had no effect on triceps surae mechanical properties. These results may be attributed to opposing adaptations between different types of training that are usually implemented in football. Alternatively, the minimum strain amplitude and/or frequency threshold of the triceps surae required to trigger adaptations of mechanical properties might not be achieved by football players with football training and matches.  相似文献

Predictors of reading and comprehension abilities in bilingual and monolingual children: a longitudinal study on a transparent language     

Stéphanie Bellocchi  Valentina Tobia  Paola Bonifacci 《Reading and writing》2017,30(6):1311-1334

Many studies have shown that learning to read in a second language (L2) is similar, in many ways, to learning to read in a first language (L1). Nevertheless, reading development also relies upon oral language proficiency and is greatly influenced by orthographic consistency. This longitudinal study aimed to analyze the role of linguistic predictors (phonological awareness, letter knowledge, pseudoword repetition, morphosyntactic comprehension, lexical knowledge and rapid naming) in reading outcomes (fluency, accuracy and comprehension) in a group of bilingual children (n = 30) reading Italian as an L2, compared to a group of monolingual children (n = 56). We ran a multi-group structural equation model. Our findings showed that rapid automatized naming was a significant predictor of reading speed in both groups. However, the study revealed different patterns of predictors for reading accuracy, predictors for monolinguals being LK, phonological awareness and lexical knowledge, while pseudoword repetition was a predictor for bilinguals. Morphosyntactic comprehension was the most significant predictor of comprehension skills in bilingual children. Implications for clinical and educational settings are discussed.  相似文献
