Cultivar Grillo vines are characterized by problems with flower biology (the fertility of basal buds) and fructification (millerandage). In this study, to manage the variability in bunch weight with winter pruning and to program others canopy management practices (i.e. early defoliation), three different treatments of bud load were set up by leaving the cane with 3, 6 or 10 buds. The effects of bud load and cane length were studies regarding bud fertility, shoot leaf area, and the number of flowers and berries, as well as the relationship between leaf area and percentage of fruit set, leaf area/flower and percentage of fruit set, and the number of hens and chicks berries. Shoots in the distal position had higher values of fertility and inflorescences with a greater number of flowers, while no ‘apical’ effect of the buds emerged. A good relationship was found between fruit set and the number of flowers, leaf area at flowering and yield, and square centimeters/flower and percentage of fruit set. Cane length was found to be a valid tool for managing bunch weight variability; the value of the leaf area/flower can be used to program early defoliation practice carried out to manage berry set.

Almond spurs are known to be the primary bearing unit in almond tree and are subject to alternate bearing. Fruits are a strong sink in bearing spurs and can influence spur leaf growth. At the same time the percent of flowers that set fruit on a spur (spur relative fruit set) could be influenced by the competition among multiple flowers/fruits borne on the same spur as well as by limited leaf area on the same spur. The aim of the present work was to investigate the relationship between current-year spur leaf area and spur absolute and relative fruit set. Approximately 2400 spurs were tagged and followed over 6 years and data concerning spur leaf area, number of flowers per spur, and number of fruits per spur were collected. Spur leaf area was reduced in fruiting spurs in comparison with non-fruiting spurs according to the number of fruits borne by each spur. This phenomenon contributes to spur alternate bearing because spur flowering and survival in the next year are a function of the leaf area in the current year. Relative fruit set in almond appears to be negatively associated with current-year spur leaf area. Competition among fruits on the same spur did not appear to influence spur relative fruit set.

The aim of this paper is to analyze how professional football clubs manage relationships with their most important stakeholders and their multiple expectations in an efficient framework. Our analysis is based on a case study about ‘Olympique de Marseille’ (OM) – a recognized French club in Ligue 1 – from a participant observation. The period covers by the study mainly runs from 2004 to 2015. We adopt a two-step approach consisting first in identifying and prioritizing club stakeholders and then in analyzing the management set up for those who matter most. Stakeholders play an important part in the way club is managed, especially those defined as definitive given their power, legitimacy and urgency attributes. Relationships with the latter can take different forms from involvement to control. Moreover they do not always exist through pre-defined procedures insofar as a significant part of them remains informal. This study enriches the knowledge of the environment of professional football clubs by taking their stakeholders into account. Recommendations are made to improve their stakeholder management practices by considering the specific nature of each relationship, the importance of dialogue in the relationship, the articulation of the formal and informal dimensions of the relationship, the regularity of the relationship and the flexibility of the relationship.

Three techniques were incorporated for drying clay-rich specimens: air-drying, freeze-drying and critical point drying. In air-drying, the specimens were set out for several days to dry or were placed in an oven (80°F) for several hours. The freeze-dried specimens were frozen by immersion in liquid nitrogen or in isopentane at near liquid nitrogen temperature and then were immediately placed in the freeze-dry vacuum chamber. The critical point specimens were molded in agar immediately after sampling. When the agar had set up the dehydration series, water-alcohol-amyl acetate-CO2 was carried out. The objectives were to compare the fabric plasmas (clays and precipitates), fabricskeletons (quartz grains) and the relationship between them for each drying technique. The three drying methods are not only applicable to the study of treated soils, but can be incorporated into all SEM clay soil studies.

The present study was conducted to examine the relationship between organisational stress and organisational citizenship behaviours (OCBs) in employees of call centers. The study also further explored as how stress at work set-up has negative impact on OCBs. A sample of 250 employees working in call centre of Gurgaon belonging to an age group of 25-30 years were selected on availability basis. All were working married couples living in nuclear families. Job stress survey (Spielberger & Vagg, 1999) and Organisational Citizenship Behaviour (Bateman & Organ, 1983) were administered. Data was analysed by using simple correlation and multiple regression. Results showed the negative relationship between organisational stress and OCBs. Results of regression analysis also exhibited the negative impact of stress on OCBs. The implications for the employees are discussed.

This study aims to determine and understand the relationship between work motivation and participatory leadership with the work behavior of the Functional Staff of the Education and Culture Office of East Nusa Tenggara Province because the Province of East Nusa Tenggara is one of the provinces whose development and growth is relatively slower compared to other provinces in Indonesia. The study population was the functional staff who did not have a structural position of 94 people. Samples were taken as many as 75 people. Data collection using a questionnaire instrument.Based on hypothesis testing, this study found: (1) there was a relationship between work motivation and work behavior in which work motivation contributed 49.29% to work behavior, (2) there was a positive relationship between participative leadership and work behavior in which participative leadership contributed 51.49% of work behavior, and there is a positive relationship between work motivation and participatory leadership together with work behavior. Where work motivation and participatory leadership together contribute 67.01% to work behavior. From the three findings, the conclusions of this study are stated that: (a) Work behavior provides a good relationship to increase work motivation, (b) Work behavior can be improved by considering participatory leadership, by involving employees in every decision making, respecting opinions and proposals employees, and enhance collaboration.

Employee engagement is becoming an important area of focus by many HR consultancies in the recent years. Organizations having engaged employees tend to out-perform than employees who are not engaged or disengaged, also it will enable them to compete better in their industry resulting in higher performance, lower turnover, more profitability etc., Despite of all this there are still some industries who are ignorant and neglect the importance of having engaged employees. Therefore there is a necessity for more of academic research on employee engagement which helps in creating awareness to these organizations about the prominence of focusing on employee engagement and the findings will also augments the existing literature on employee engagement. The study was conducted on 433 employees working in travel organizations set up in Bangalore with the purpose of determining the relationship psychological climate (antecedent) has on employee engagement and in turn its relationship with organizational citizenship behavior (outcome). The study also determines the mediating relationship of employee engagement between PC and OCB.

Abstract Orienteering has gradually changed from a professional sport to a civilian sport. Especially in recent years, orienteering has been widely popularized. Many colleges and universities in China have also set up this course. With the improvement of people’s living conditions, orienteering has really become a leisure sport in modern people’s life. The reduced difficulty of sports enables more people to participate, but it also exposes a series of problems. As the existing positioning technology is relatively backward, the progress in personnel tracking, emergency services, and other aspects is slow. To solve these problems, a new intelligent orienteering application system is developed based on the Internet of things. ZigBee network architecture is adopted in the system. ZigBee is the mainstream scheme in the current wireless sensor network technology, which has many advantages such as convenient carrying, low power consumption, and signal stability. Due to the complex communication environment in mobile signal, the collected information is processed by signal amplification and signal anti-interference technology. By adding anti-interference devices, video isolators and other devices, the signal is guaranteed to the maximum extent. In order to verify the actual effect of this system, through a number of experimental studies including the relationship between error and traffic radius and the relationship between coverage and the number of anchor nodes, the data shows that the scheme studied in this paper has a greater improvement in comprehensive performance than the traditional scheme, significantly improving the accuracy and coverage. Especially the coverage is close to 100% in the simulation experiment. This research has achieved good results and can be widely used in orienteering training and competition.
