DRIS norms validation for sugarcane crop

The objectives of this study were to evaluate the relationship between the diagnosis and recommendation integrated system (DRIS) indices and foliar nutrient concentrations, to establish optimum foliar nutrient concentrations with DRIS and to validate the DRIS norms for sugarcane crop. Foliar nutrient concentrations from 126 sugarcane commercial fields were analyzed during the 1996/97 season, to calculate DRIS indices. Regression analysis was used to fit a model relating DRIS indices to nutrient concentrations. Experiments were carried out during the 1997/98 season, whose treatments consisted of the addition of the most limiting nutrients according to DRIS. A new diagnosis was performed. At the end of 1997/98 season, the yields of each plot were collected. Analysis of variance and Duncan test (5%) were used for the evaluation of the collected data. There was a positive and significant relationship between sugarcane foliar nutrient concentrations and DRIS indices. The optimum foliar nutrient concentrations for sugarcane are: 13.4 g ha-1 for N, 1.91 g ha-1 for P, 12.2 g ha-1 for K, 2.99 g ha-1 for Ca, 2.15 g ha-1 for Mg, 1.61 g ha-1 for S, 4.48 mg ha-1 for Cu, 67.8 mg ha-1 for Mnand 11.7 mg ha-1 for Zn. DRIS norms evaluated are useful to correct nutritional imbalances and to increase sugarcane yield.

Multidisciplinary Safety Team (MDST) Factors of Success, 2014

This project included a literature review and summary that focused on subjects related to team building, team/committee member motivational strategies, and tools for effective and efficient committee meetings. It also completed an online survey of multidisciplinary safety team (MDST) members that focused on methods to increase meeting attendance and the identification of factors that make MDSTs successful. The survey had a response rate of about 15 percent. Finally, three small MDST focus groups were held and the participants discussed information similar to that investigated by the online survey. The results of these three activities were similar and complementary. In general, the outcomes of all three tasks show that a well-designed agenda that has items relevant to the meeting attendees is very important. In addition, the literature, online survey, and focus group results identified other characteristics that define a good team or MDST. Some of these characteristics included effective and consistent leadership, members that are allowed to provide input and have an impact, members that are vested in the activities of the group, and a match between the interests of the members and the focus/mission/purpose of the meetings/group. Meetings that are scheduled well in advance of the meeting date, include time for networking, local safety activity discussions, hands-on activities/tasks, and/or some type of educational or informational presentation or activity also appeared to be the most desirable. Lastly, it was shown that MDSTs can thrive and be successful through various means, but the ability to focus on a specific safety issue when the group is first organized was suggested as a benefit that could be of assistance for long-term sustainability.

Chaotic dynamics and team effectiveness: evidence from professional basketball

Considering teams as complex adaptive systems (CAS) this study deals with changes in team effectiveness over time in a specific context: professional basketball. The sample comprised 23 basketball teams whose outcomes were analysed over a 12-year period according to two objective measures. The results reveal that all the teams showed chaotic dynamics, one of the key characteristics of CAS. A relationship was also found between teams showing low-dimensional chaotic dynamics and better outcomes, supporting the idea of healthy variability in organizational behaviour. The stability of the squad was likewise found to influence team outcomes, although it was not associated with the chaotic dynamics in team effectiveness. It is concluded that studying teams as CAS enables fluctuations in team effectiveness to be explained, and that the techniques derived from nonlinear dynamical systems, developed specifically for the study of CAS, are useful for this purpose.

Women in leadership: Three essays

GENDER EMPOWERMENT: EFFECTS OF GODS, GEOGRAPHY, AND GDP¦Fenley, M., & Antonakis, J.¦ABSTRACT¦We examined the determinants of women's empowerment in the economy and political leadership in 178 countries. Given the androcentric nature of most religions, we hypothesized that high degrees of country-level theistic belief create social conditions that impede the progression of women to power. The dependent variable was the Gender Empowerment index of the United Nations Development Program, which captures the participation of women in political leadership, management, and their share of national income. Controlling for GDP per capita as well as the fixed-effects of the dominant type of religion and legal origin and instrumenting all endogenous variables with geographic or historical variables, our results show that atheism has a significant positive effect on gender empowerment. These results are driven by the rule of law, which in addition to being a catalyst for economic development, appears to crowd-out the informal regulation of behavior due to religious norms.¦DEVELOPING WOMEN LEADERS: COMPARING A TRANSFORMATIONAL AND A CHARISMATIC LEADERSHIP INTERVENTION¦Fenley, M., Jacquart, P., & Antonakis, J.¦ABSTRACT¦Along with a gender imbalance in leadership role occupancy, most leadership interventions have been conducted with samples of men. We conducted an experiment wherein we assigned female participants (n = 38, mean age = 35 years) to one of two conditions: Transformational (i.e., "standard") leadership training or charismatic leadership training. The two interventions were essentially equivalent, except that we also focused on developing the "charismatic leadership tactics" (e.g., rhetorical skills) of participants in the charismatic condition. After the interventions, we randomly assigned participants into problem-solving teams that required extensive interaction. Each team had an equal number of participants having received transformational training or charismatic training. At the end of the team exercises, participants rated each of their team members on a leadership prototypicality measure. Results indicated that those who received charismatic training scored higher (a) on prototypicality (standardized  = .42) and (b) on a test of declarative knowledge of charismatic rhetorical strategies (i.e., a manipulation check, standardized  = .76). Furthermore, the score on the test fully mediated the effect of the treatment on prototypicality (standardized indirect  = .32). We discuss the importance and practical implications of these results.¦CHANGING ATTITUDES TOWARDS WOMEN IN A MALE SEX-TYPE WORK ENVIRONMENT: EVIDENCE FROM A FIELD EXPERIMENT IN EUROPEAN ATHLETICS¦Fenley, M.¦ABSTRACT¦Most sports organizations have a similar gender gap in leadership as do the majority of non-sport organizations. Women's careers sputter somewhere at coaching level positions and few women obtain top leadership positions. Greater awareness of gender inequalities in general, and in leadership in particular, could decrease gender discrimination and increase women's presence at upper levels. The goal of this study was to evaluate the impact of an intervention using an online gender awareness exercise. Participants (n = 1,001 participants, n = 32 countries) were randomly assigned to one of eight conditions in a 2 (a discriminating perspective-taking story or a non-discriminating perspective-taking story) by 2 (gender quiz or no gender quiz) by 2 (diversity quiz or no diversity quiz) factorial design. The results show that the online perspective taking exercise changed initial sexist attitudes. Participants having taken a diversity quiz had less sexist attitudes (as measured by the Modern- and Old-fashioned sexism scale) than did participants who did not take the diversity quiz (irrespective of perspective-taking story). The combination of having taken a diversity quiz with a gender quiz had the biggest impact on attitudes for the non-discriminating story.

L'hypnose intégrée aux soins de patients brûlés: impact sur le niveau de stress de l'equipe soignante [Hypnosis integrated in burn care: impact on the healthcare team's stress].

Hypnosis for burn care was introduced in 2004 in the CHUV burn center showing great benefit for burned patients. Whereas advantages of hypnosis for the patient are well established, the impact on the medical staff remains poorly assessed. This manuscrit reviews current attested benefits of hypnosis for patients, specially for burned patients. The results of a recent study assessing the impact of hypnosis on the staffs level of stress caused by burn treatment, will also be introduced.

Team Effectiveness in Patient Health Management: An Overview of Reviews

Background: The desire to improve the quality of health care for an aging population with multiple chronic diseases is fostering a rapid growth in inter-professional team care, supported by health professionals, governments, businesses and public institutions. However, the weight of evidence measuring the impact of team care on patient and health system outcomes has not, heretofore, been clear. To address this deficiency, we evaluated published evidence for the clinical effectiveness of team care within a chronic disease management context in a systematic overview. Methods: A search strategy was built for Medline using medical subject headings and other relevant keywords. After testing for perform- ance, the search strategy was adapted to other databases (Cinhal, Cochrane, Embase, PsychInfo) using their specific descriptors. The searches were limited to reviews published between 1996 and 2011, in English and French languages. The results were analyzed by the number of studies favouring team intervention, based on the direction of effect and statistical significance for all reported outcomes. Results: Sixteen systematic and 7 narrative reviews were included. Diseases most frequently targeted were depression, followed by heart failure, diabetes and mental disorders. Effective- ness outcome measures most commonly used were clinical endpoints, resource utilization (e.g., emergency room visits, hospital admissions), costs, quality of life and medication adherence. Briefly, while improved clinical and resource utilization endpoints were commonly reported as positive outcomes, mixed directional results were often found among costs, medication adherence, mortality and patient satisfaction outcomes. Conclusions: We conclude that, although suggestive of some specific benefits, the overall weight of evidence for team care efficacy remains equivocal. Further studies that examine the causal interactions between multidisciplinary team care and clinical and economic outcomes of disease management are needed to more accurately assess its net program efficacy and population effectiveness.

The last days of dying stroke patients referred to a palliative care consult team in an acute hospital.

BACKGROUND AND PURPOSE: Needs of patients dying from stroke are poorly investigated. We aim to assess symptoms of these patients referred to a palliative care consult team, and to review their treatment strategies. METHODS: All charts of patients dying from stroke in a tertiary hospital, and referred consecutively to a palliative care consultant team from 2000 to 2005, were reviewed retrospectively. Symptoms, ability to communicate, treatments, circumstances and causes of death were collected. RESULTS: Forty-two patients were identified. Median NIH Stroke Scale on admission was 21. The most prevalent symptoms were dyspnoea (81%), and pain (69%). Difficulties or inability to communicate because of aphasia or altered level of consciousness were present in 93% of patients. Pharmacological respiratory treatments consisted of anti-muscarinic drugs (52%), and opioids (33%). Pain was mainly treated by opioids (69%). During the last 48 h of life, 81% of patients were free of pain and 48% of respiratory distress. The main causes of death were neurological complications in 38% of patients, multiple medical complications in 36%, and specific medical causes in 26%. CONCLUSIONS: Patients dying from stroke and referred to a palliative care consult team have multiple symptoms, mainly dyspnoea and pain. Studies are warranted to develop specific symptoms assessment tools in non-verbal stroke patients, to accurately assess patients' needs, and to measure effectiveness of palliative treatments.

Diversity management and team leadership in a nonprofit organization. Case: AIESEC in Finland

Tutkimuksen tarkoituksena on selvittää kuinka moninaisuus ja sen johtaminen näkyvät voittoa tavoittelemattoman järjestön tiimityössä, kuinka moninaisuus ja tiimityö pystyvät selittämään motiiveja työskennellä voittoa tavoittelemattomassa järjestössä ja mitä tulisi huomioida tiimityön ja tiimin johtajuuden osalta, kun moninaisuus ja voittoa tavoittelemattoman järjestön luonne otetaan huomioon. Tämä tutkielma on laadullinen tutkimus, jossa tutkimusmenetelminä on käytetty yhdeksää teemahaastattelua, edellisen tutkimuksen tuloksia (Astikainen, 2005) sekä havainnointia. Tutkimuksen perusteellavoidaan todeta, että voittoa tavoittelemattoman järjestön luonne, tiimityö tai moninaisuus eivät sinällään merkitse paljoakaan tulosten kannalta, vaan niiden keskinäiset yhteydet. Nämä yhdessä, oikein hyödynnettynä, vaikuttavat työntekijöiden motivaatioon ja sitä kautta organisaation tuloksiin.

Cardiorespiratory and Cardiac Autonomic Responses to 30-15 Intermittent Fitness Test in Team Sport Players

Buchheit, M, Al Haddad, H, Millet GP, Lepretre, PM, Newton, M, and Ahmaidi, S. Cardiorespiratory and cardiac autonomic responses to 30-15 Intermittent Fitness Test in team sport players. J Strength Cond Res 23(1): xxx-xxx, 2009-The 30-15 Intermittent Fitness Test (30-15IFT) is an attractive alternative to classic continuous incremental field tests for defining a reference velocity for interval training prescription in team sport athletes. The aim of the present study was to compare cardiorespiratory and autonomic responses to 30-15IFT with those observed during a standard continuous test (CT). In 20 team sport players (20.9 +/- 2.2 years), cardiopulmonary parameters were measured during exercise and for 10 minutes after both tests. Final running velocity, peak lactate ([La]peak), and rating of perceived exertion (RPE) were also measured. Parasympathetic function was assessed during the postexercise recovery phase via heart rate (HR) recovery time constant (HRRtau) and HR variability (HRV) vagal-related indices. At exhaustion, no difference was observed in peak oxygen uptake (&OV0312;o2peak), respiratory exchange ratio, HR, or RPE between 30-15IFT and CT. In contrast, 30-15IFT led to significantly higher minute ventilation, [La]peak, and final velocity than CT (p < 0.05 for all parameters). All maximal cardiorespiratory variables observed during both tests were moderately to well correlated (e.g., r = 0.76, p = 0.001 for &OV0312;o2peak). Regarding ventilatory thresholds (VThs), all cardiorespiratory measurements were similar and well correlated between the 2 tests. Parasympathetic function was lower after 30-15IFT than after CT, as indicated by significantly longer HHRtau (81.9 +/- 18.2 vs. 60.5 +/- 19.5 for 30-15IFT and CT, respectively, p < 0.001) and lower HRV vagal-related indices (i.e., the root mean square of successive R-R intervals differences [rMSSD]: 4.1 +/- 2.4 and 7.0 +/- 4.9 milliseconds, p < 0.05). In conclusion, the 30-15IFT is accurate for assessing VThs and &OV0312;o2peak, but it alters postexercise parasympathetic function more than a continuous incremental protocol.

Extension des prestations de type "équipe mobile" aux foyers socio-éducatifs: projet pilote dans le canton de Vaud [Extension of mobile team services to socio-educational home: pilot project in the Vaud canton].

L'objectif principal de ce projet d'extension des prestations, de type Antenne d'intervention dans le milieu pour enfants et adolescents (AIMEA) aux foyers socio-éducatifs pour l'ensemble du canton de Vaud, vise à décloisonner les champs socio-éducatifs et pédopsychiatriques. 64 patients ont fait l'objet d'une évaluation au cours de la phase pilote (après une année de fonctionnement). De plus, une enquête de satisfaction a été effectuée soit à la fin du suivi, soit à la fin de la phase pilote de ce projet (au 31.12.2012). Cette expérience très positive, relevée par une grande majorité des acteurs impliqués dans la prise en charge socio-éducative et pédopsychiatrique des mineurs, suscite un désir d'extension des prestations de type équipe mobile à d'autres structures ou à d'autres types de situations. The main objective of this project about mobile team service extension to the socio-educational home of the whole Vaud canton targets to decompartmentalize the socio-educational and youth-psychiatry domains. 64 patient were assessed during this pilot phase (after one-year functioning). In addition, a satisfaction survey was done either at the end of the follow up or at the end of the pilot phase of the project (31.12.2012). This experience was very positive as highlighted by the vast majority of the person involved in the socio-educational and youth-psychiatric domains taking care of youth. A desire of extension of mobile team service to other institutional structure or other situations was expressed.

The role of trust and its evolution in distributed teams in a multinational organisation

Tutkimuksen päätavoitteena on ollut selvittää miten kansallinen ja organisaatiokulttuuri, niihin liittyvät normit ja arvot edesauttavat tai vaikeuttavat luottamuksen kehittymistä monikulttuurisissa tiimeissä maailmanlaajuisessa organisaatiossa. Tutkimuksen avulla haluttiin myös selvittää miten luottamus kehittyy hajautetuissa monikansallisissa tiimeissä WorldCom Internationalissa. Empiirinen tutkimusmenetelmä perustuu kvalitatiivisiin teemahaastatteluihin, jotka tehtiin WorldComin työntekijöille. Tutkimuksessa havaittiin, ettei yhteisten sosiaalisten normien merkitys luottamuksen syntymiselle ole niin merkittävä, koska WorldComin yhtenäiset toimintatavat sekä hallitseva amerikkalaisen emoyhtiön "kotikulttuuri" muodostavat yhtenäiset toimintalinjat tiimeissä. Tietokonevälitteisen kommunikoinnin jatkuva käyttö on edesauttanut työntekijöiden ns. sosiaalisen älyn kehittymistä, sillä henkilökohtaisen tapaamisen puuttuminen kehittää vastaavasti taitoja aistia ja tulkita sähköpostien tai puhelinneuvotteluiden aikana välittyviä vastapuolen "näkymättömiä" vihjeitä.
