Leading Teams

This note presents an overview of some fundamental characteristics of high-performing teams and suggestions for team leaders on how to manage them. The note summarizes some of the concepts included in the book Organizing Genius (by Warren Bennis and Patricia Biederman), adds both an effective-role framework (task versus process and creativity versus pragmatism) and a brief introduction to small-group life cycles, and ends by encouraging team leaders to be aware of these dimensions as they try to create and manage high-performing teams. Excerpt UVA-OB-0655 LEADING TEAMS While not ignoring or neglecting the individual, we should devote far more thought to teams: to the selection, development, and training of teams, to the qualifications, experience, and achievements of teams, and above all to the psychology, motivation, composition, and behavior of teams. —Anthony Jay &#183; An information systems project leader struggles to organize a massive change effort in an urban municipal modernization program involving hundreds of people. &#183; An account executive for a global financial services firm wonders how to coordinate the efforts of colleagues in eight different cities on behalf of a single global client.

How Does Transformational Leadership Promote Innovation in Construction? The Mediating Role of Innovation Climate and the Multilevel Moderation Role of Project Requirements

Innovation plays a critical role in the sustainable development of the construction industry. This research aims at examining transformational leadership’s role in shaping employees’ innovative behavior by analyzing the mediating effect of innovation climate and the cross-level moderating effect of innovativeness as a project requirement. To achieve this aim, a questionnaire survey was conducted with 300 construction industry professionals in China and 251 valid replies were received. Data collected by the questionnaire were analyzed using the method of hierarchical linear modeling (HLM). The results showed that transformational leaders could nurture a mutual climate for innovation to motivate employees’ innovative behaviors. In addition, innovativeness as a project requirement at the project level strengthens the indirect link amongst transformational leadership and innovative behavior via the innovation climate. Therefore, in the presence of higher innovativeness as a project requirement, transformational leadership is more prone to exert a positive influence upon an individual’s innovative behavior via the perceived innovation climate. The research findings improve understanding of the roles of leadership and innovation climate in affecting individual behavioral outcomes, and could help project managers and leaders encourage innovative ideas within project organizations.
Geometrical evolution of developed interfaces

Consider the reaction-diffusion equation in R"xR+ : ut-h2Au + <p{u) = 0 ; <p is the derivative of a bistable potential with wells of equal depth and A is a small parameter. If the initial data has an interface, we give an asymptotic expansion of arbitrarily high order and error estimates valid up to time 0(h~2). At lowest order, the interface evolves normally, with a velocity proportional to the mean curvature. Résumé. Soit l'équation de réaction-diffusion dans R* x R+ , ut — h1 Au + ç»(«) = 0, avec q> la dérivée d'un potentiel bistable à puits également profonds et h un petit paramètre. Pour une condition initiale possédant une interface, on donne un développement asymptotique d'ordre arbitrairement élevé, ainsi que des estimations d'erreur valides jusqu'à un temps en 0(h~2) .

What Are Teachers' Perceptions of Teaching in Different Classroom Contexts?.

In 1986, the Tennessee legislature authorized the Student/Teacher Achievement Ratio (STAR) project. At the end of the school year, interviews were held with teachers from kindergarten through third-grade levels on their perceptions of teaching either in a small class, in a regular class with a . ull-time aide, or in a regular class. The following categories of teacher perceptions were identified: (1) grouping of pupils' (2) physical and social climate, (3) learning centers and activities, (4) classroom management, (5) pupil evaluation, (6) teacher morale, (7) pupil achievement, (8) instructional practices, (9) teacher planning, and (10) teacher/student relationship. Time was a dominant theme observed throughout small class and regular/aide class teacher interview responses. The amount and pace of academic content covered was the most pervasive time related difference noted by all of the small class teachers. Increased opportunities for more individualized instruction emerged as a second dominant theme when small and regular/aide class teachers talked 'out differences between teaching in a small or a regular size class. A discussion is presented on findings in eacri of the identified categories of teacher perceptions.

Hub-Airport Competition: Connecting Time Differentiation and Concession Consumption

This paper develops a network model to analyse the economic effects resulting from the non-price competition between the home country's and neighbouring country's hub-airports. Focusing on the trade-off relationship between the length of the connecting time in the hub-airport and the consumption opportunities of the transfer passengers, we demonstrate theoretically that even though the hub-airport bears a cost disadvantage over its rival in providing the hub-airport service, it still has a chance to earn more profits than its rival by the setting of the connecting time. This finding suggests a new methodology for hub-airports that attempt to alleviate price competition.
Exploring the Recent Trends of Paraphrase Detection

This study is to examine paraphrase detection (PD) for diagnostic purposes. Which is defined as the capability to find and discover the similarity between sentences that are written in a natural language? Where detecting similar sentences written in natural language is extreme importance and it is very essential for computer software used in plagiarism detection, Q and A automated systems, text mining, authorship authentication and text recapitulation. The goal of paraphrase detection is to detect whether two statements have the identical semantic or not. There is hundreds of empirical research in this direction. This study will focus on the discussion of recent studies of the PD methods and will categorize them in two categories, supervised learning and unsupervised learning. Also will give an idea about text similarity, machine learning and deep learning approaches. The performance of the selected researches is assessed by how accurate the F-measures are in detecting paraphrase in Microsoft Research Paraphrase Corpus (MSPR).

Shadow Prices for Undesirables in Swedish Industry: Indication of Environmental Kuznets Curves?

In this note, we estimate time series of shadow prices for Swedish emissions of CO2, SO2 , and VOC for the period 1918 - 1994. The shadow prices are in the second step related to income to explain the environmental Kuznets curves previously found for Swedish data on the three emissions. A Shephard distance function approach is used to estimate a structural model of the industry’s production process in order to calculate the opportunity costs of a reduction in the emissions. We conclude that the times series of the shadow prices obtained using this approach do not show support for EKCs for Swedish industry
Do Asian Pink Salmon Affect the Survival of Bristol Bay Sockeye Salmon ?

Werts@gci.net A. Wertheimer. Fig. 1. Average smolt-to-adult survival for three Bristol Bay sockeye salmon stocks (Kvichak, Egegik, and Ugashik) for the smolt years 1977-1997 and corresponding adult Asian pink salmon abundance. Error bars are SE of means. The abundance of pink salmon and chum salmon in the subarctic North Pacific Ocean are at historically high levels (Eggers 2009; Irvine et al. 2009; Ruggerone et al. 2010a). This increased abundance has raised concerns that density dependent interactions in the ocean may reduce growth and survival of conspecifics and associated salmon species (Ruggerone and Neilson 2004; Helle et al. 2007; Ruggerone et al. 2010a). Ruggerone et al. (2003) found that competition between Asian pink salmon and Bristol Bay sockeye salmon reduced the growth of sockeye salmon. They suggested average sockeye smolt-to-adult survival rates for three large stocks (Kvichak, Egegik, and Ugashik) outmigrating in 1977-1997 were significantly lower for smolts entering the ocean during even-numbered years and interacting with abundant odd-year Asian pink salmon than for smolts entering the ocean during odd-numbered years (Fig. 1). However, their analysis did not link smolt survival directly to the highly variable annual abundance of Asian pink salmon. If the large variation in average oddand even-year smolt survival was caused by the differences in average oddand even-year pink salmon abundances, we would expect the actual annual abundance of pink salmon to have a significant and measurable impact on annual variation in smolt survival.
Income Inequality between Formal-Informal Employees Based on Education Group

Integrally, the informal sector deals with the formal sector with pro-cyclical nature or as a complementary sector. Such conditions allow for wage disparity between sectors even in the same education group. Thus, this study seeks to determine the determinants of wage inequality between formal and informal employees in skilled and unskilled workers in Indonesia in 2017 using Blinder-Oaxaca decomposition. The results showed that the discrimination factor had a greater inﬂuence than the endowment factor on wage inequality and the endowment factors that contributed to the increase in wage inequality between the two groups were age squared, experience, and job training.
Frictional Unemployment with Stochastic Bubbles

Bubbles are recurrent events, which contribute to both macroeconomic and employment volatility. We introduce stochastic bubbles in the standard search-and-matching model of the labor market. The economy alternates between latent and bubbly states, each being associated with a distinct solution for the market value of firms (respectively, stable or explosive). Bubbles in firm value induce distortions in hiring decisions and wages, which we explicitly characterize. Faced with bubbles, the social planner optimally deviates from the standard Hosios efficiency condition. The optimal share of workers in total surplus must be above the elasticity of hiring rates, by a small but increasing amount as the bubble expands. Finally, our specification for bubbles significantly improves the quantitative ability of the model to match U.S. data, along both real and financial dimensions.
Polynomial time deterministic identity testing algorithm for Σ[3]ΠΣΠ[2] circuits via Edelstein–Kelly type theorem for quadratic polynomials

In this work we resolve conjectures of Beecken, Mitmann and Saxena [BMS13] and Gupta [Gupta14], by proving an analog of a theorem of Edelstein and Kelly for quadratic polynomials. As immediate corollary we obtain the first deterministic polynomial time black-box algorithm for testing zeroness of Σ[3]ΠΣΠ[2] circuits.
Executive Constraint, Political Stability and Economic Growth

Previous studies have argued that democracy diminishes the extent to which contests over political leadership depress economic growth, by reducing the violence and uncertainty attendant on such contests. We reconsider the theoretical basis for this claim, highlighting the separate roles of executive constraint and electoral accountability. Exploiting panel data from 1850-2005, we show that the executive’s horizontal accountability to the legislature significantly moderates the economic downturns associated with leadership turnover, while its vertical accountability to the electorate does not. These results suggest that, in terms of moderating succession-related downturns and thereby promoting steadier economic growth, the health of legislatures is more important than the health of elections.
Variability in Familiar and Novel Talkers : E ects on Mora Perception and Talker Identi cation

Contextual tuning theories of talker normalization state that listeners can use information about a talker's vocal characteristics stored in working memory to facilitate recognition of that talker's speech [9]. We investigated whether people can use information about a familiar talker's voice, stored in long-term memory [12, 10], in the same way. That is, can subjects circumvent normalization processes when listening to highly familiar talkers, such as familiymembers? We found that familiarity with a talker's voice facilitated performance in a talker identi cation task, and also in a mora identi cation task with degraded stimuli. However, in a monitoring paradigm that typically results in faster performance in single-talker than multiple-talker conditions[9], we found the typical normalization e ect for both familiar and unfamiliar talkers. Thus, while information about talkers that listeners have in long-term memory can be used strategically to facilitate, e.g., segment identi cation, that information is not available until the initial processes of talker normalization are complete. We discuss the implications of the results for theories of talker normalization and talker identi cation. £ key words speech perception, talker variability, talker identi cation
Modification of PSf/SPSf Blended Porous Support for Improving the Reverse Osmosis Performance of Aromatic Polyamide Thin Film Composite Membranes

In this study, modification of polysulfone (PSf)/sulfonated polysulfone (SPSf) blended porous ultrafiltration (UF) support membranes was proposed to improve the reverse osmosis (RO) performance of aromatic polyamide thin film composite (TFC) membranes. The synergistic effects of solvent, polymer concentration, and SPSf doping content in the casting solution were investigated systematically on the properties of both porous supports and RO membranes. SEM and AFM were combined to characterize the physical properties of the membranes, including surface pore natures (porosity, mean pore radius), surface morphology, and section structure. A contact angle meter was used to analyze the membrane surface hydrophilicity. Permeate experiments were carried out to evaluate the separation performances of the membranes. The results showed that the PSf/SPSf blended porous support modified with 6 wt % SPSf in the presence of DMF and 14 wt % PSf had higher porosity, bigger pore diameter, and a rougher and more hydrophilic surface, which was more beneficial for fabrication of a polyamide TFC membrane with favorable reverse osmosis performance. This modified PSf/SPSf support endowed the RO membrane with a more hydrophilic surface, higher water flux (about 1.2 times), as well as a slight increase in salt rejection than the nascent PSf support. In a word, this work provides a new facile method to improve the separation performance of polyamide TFC RO membranes via the modification of conventional PSf porous support with SPSf.
Perceived Novelty Support and Psychological Needs Satisfaction in Physical Education

In recent years, novelty has been proposed as a potential fourth basic psychological need. In the present study, the behavior of novelty resulting from support from the Physical Education teacher was evaluated in 723 students with an average age of 13.30 years old. The first objective was to validate the Support for Basic Psychological Needs-4 (SBPN-4) in Physical Education questionnaire, which included support for the novelty factor. The second objective was to test the mediation model in order to confirm the effect of support for novelty in relation to basic psychological needs and intrinsic motivation. The results obtained show that the Support for Basic Psychological Needs-4 (SBPN-4) questionnaire is a valid and reliable tool. On the other hand, support for novelty predicts satisfaction of basic psychological needs, particularly novelty satisfaction, which in turn predicts intrinsic motivation. These results show how the students are capable of perceiving the teacher’s support for novelty and how this positively influences their intrinsic motivation. Further investigations are required to continue developing our knowledge of the role of novelty as a basic psychological need.
Utilization of magnesium-rich synthetic gypsum as magnesium fertilizer for oil palm grown on acidic soil

A study was conducted to determine the impact of applying different sources of Mg, namely kieserite, ground magnesium limestone (GML) and Mg-rich synthetic gypsum (MRSG) on an acid tropical soil, oil palm growth and production. Besides high amount of Mg and Ca, MRSG contains S. Exchangeable Ca in the untreated soil of the plantation was 0.64 cmolc kg-1, but its critical level to sustain oil palm growth was 0.9 cmolc kg-1. MRSG was applied in the plantation as Mg-fertilizer; however, since Ca is also a limiting nutrient, oil palm growth was correlated (r = 0.69) with Ca supplied by the MRSG. Mg needed to sustain oil palm production is normally supplied by kieserite. Its requirement can be met at a lower cost compared to that of the kieserite by using MRSG. Due to MRSG treatment, exchangeable Ca in the soil increased steadily to satisfy the requirement of oil palm for fruit bunches production. From the glasshouse and field study, it was observed that MRSG applied at 1.5 times the recommended rate gave results comparable to that of the kieserite. MRSG treatment resulted in the increase of soil pH to >5 that precipitated Al3+ as inert Al-hydroxides, which eventually enhanced oil palm seedlings growth. Thus, MRSG can also replace GML to increase soil pH and satisfy the Ca and Mg requirement of oil palm. It can be concluded that MRSG has the potential to be used as a source of Mg as well as Ca for oil palm grown on acidic soil.
The Impact of Gastric Juice pH on the Intraluminal Therapy for Helicobacter pylori Infection

Background: Helicobacter pylori (H. pylori) can be topically eradicated in stomach lumen on endoscopic examination. The procedures of intraluminal therapy for H. pylori infection (ILTHPI) include the control of intragastric pH, mucolytic irrigation of the gastric mucosal surface, and a single-dose medicament containing antimicrobial agents. Aims: To detect gastric juice pH and evaluate its impact on the success rate of ILTHPI. Methods: We enrolled 324 patients with upper abdominal discomfort for endoscopic examinations. Among them, 13C-urea breath test was positive in 218 patients, where 100 underwent ILTHPI, and negative in 106. All patients had their gastric juice pH detected and set into three ranges, including normal acidity (pH < 4.0), low-level hypoacidity (pH 4.0–5.5), and high-level hypoacidity (pH ≥ 6.0). The impact of gastric juice pH on the success rate of ILTHPI was evaluated. Results: Distribution of pH level showed no significant difference between two groups of H. pylori-infected patients (p = 0.942). The eradication rate of ILTHPI is significantly lower in patients with gastric juice pH below 4 (p < 0.001). Conclusions: Detection of gastric juice pH in ILTHPI is extremely important. Rapid control of stomach pH at or above 4 for patients prior to ILTHPI is strongly recommended. (NCT03124420).
Circulatory Failure among Hospitalizations for Heatstroke in the United States

Background: This study aimed to assess the risk factors and the association of circulatory failure with treatments, complications, outcomes, and resource utilization in hospitalized patients for heatstroke in the United States. Methods: Hospitalized patients with a principal diagnosis of heatstroke were identified in the National Inpatient Sample dataset from the years 2003 to 2014. Circulatory failure, defined as any type of shock or hypotension, was identified using hospital diagnosis codes. Clinical characteristics, in-hospital treatment, complications, outcomes, and resource utilization between patients with and without circulatory failure were compared. Results: A total of 3372 hospital admissions primarily for heatstroke were included in the study. Of these, circulatory failure occurred in 393 (12%) admissions. Circulatory failure was more commonly found in obese patients, but less common in older patients aged ≥60 years. The need for mechanical ventilation, blood transfusion, and renal replacement therapy were higher in patients with circulatory failure. Hyperkalemia, hypocalcemia, metabolic acidosis, metabolic alkalosis, sepsis, ventricular arrhythmia or cardiac arrest, renal failure, respiratory failure, liver failure, neurological failure, and hematologic failure were associated with circulatory failure. The in-hospital mortality was 7.1-times higher in patients with circulatory failure. The length of hospital stay and hospitalization costs were higher when circulatory failure occurred while in the hospital. Conclusions: Approximately one out of nine heatstroke patients developed circulatory failure during hospitalization. Circulatory failure was associated with various complications, higher mortality, and increased resource utilizations.
