The Effect of Team Leader Characteristics on Learning, Knowledge Application, and Performance of Cross‐Functional New Product Development Teams

Abstract: This study examines how leadership characteristics in new product development teams affect the learning, knowledge application, and subsequently the performance of these teams. Using data from a study of 229 members from 52 high-tech new product projects, we empirically demonstrate that team learning has a strong positive effect on the innovativeness and speed to market of the new products. Moreover, a democratic leadership style, initiation of goal structure by the team leader, and his or her position within the organization were positively related to team learning. Managerial implications of these results are discussed.

An approach to understanding hydrologic connectivity on the hillslope and the implications for nutrient transport

Abstract: [1] Hydrologic processes control much of the export of organic matter and nutrients from the land surface. It is the variability of these hydrologic processes that produces variable patterns of nutrient transport in both space and time. In this paper, we explore how hydrologic ‘‘connectivity’’ potentially affects nutrient transport. Hydrologic connectivity is defined as the condition by which disparate regions on the hillslope are linked via subsurface water flow. We present simulations that suggest that for much of the year, water draining through a catchment is spatially isolated. Only rarely, during storm and snowmelt events when antecedent soil moisture is high, do our simulations suggest that mid-slope saturation (or near saturation) occurs and that a catchment connects from ridge to valley. Observations during snowmelt at a small headwater catchment in Idaho are consistent with these model simulations. During early season discharge episodes, in which the mid-slope soil column is not saturated, the electrical conductivity in the stream remains low, reflecting a restricted, local (lower slope) source of stream water and the continued isolation of upper and mid-slope soil water and nutrients from the stream system. Increased streamflow and higher stream water electrical conductivity, presumably reflecting the release of water from the upper reaches of the catchment, are simultaneously observed when the mid-slope becomes sufficiently wet. This study provides preliminary evidence that the seasonal timing of hydrologic connectivity may affect a range of ecological processes, including downslope nutrient transport, C/N cycling, and biological productivity along the toposequence. A better elucidation of hydrologic connectivity will be necessary for understanding local processes as well as material export from land to water at regional and global scales.

High-resolution climatic evolution of coastal northern California during the past 16,000 years

Abstract: Holocene and latest Pleistocene oceanographic conditions and the coastal climate of northern California have varied greatly, based upon high-resolution studies (ca. every 100 years) of diatoms, alkenones, pollen, CaCO 3 %,and total organic carbon at Ocean Drilling Program (ODP) Site 1019 (41.682°N, 124.930°W, 980 m water depth). Marine climate proxies (alkenone sea surface temperatures [SSTs] and CaCO 3 %) behaved remarkably like the Greenland Ice Sheet Project (GISP)-2 oxygen isotope record during the Balling-Allerod, Younger Dryas (YD), and early part of the Holocene. During the YD, alkenone SSTs decreased by >3°C below mean Bolling-Allerod and Holocene SSTs. The early Holocene (ca. 11.6 to 8.2 ka) was a time of generally warm conditions and moderate CaCO 3 content (generally >4%). The middle part of the Holocene (ca. 8.2 to 3.2 ka) was marked by alkenone SSTs that were consistently 1-2°C cooler than either the earlier or later parts of the Holocene, by greatly reduced numbers of the gyre-diatom Pseudoeunotia doliolus (<10%), and by a permanent drop in CaCO 3 % to <3%. Starting at ca. 5.2 ka, coastal redwood and alder began a steady rise, arguing for increasing effective moisture and the development of the north coast temperate rain forest. At ca. 3.2 ka, a permanent ca. 1°C increase in alkenone SST and a threefold increase in P. doliolus signaled a warming of fall and winter SSTs. Intensified (higher amplitude and more frequent) cycles of pine pollen alternating with increased alder and redwood pollen are evidence that rapid changes in effective moisture and seasonal temperature (enhanced El Nino-Southern Oscillation [ENSO] cycles) have characterized the Site 1019 record since about 3.5 ka.

Simultaneous 1D inversion of loop loop electromagnetic data for magnetic susceptibility and electrical conductivity

Abstract: Magnetic susceptibility affects electromagnetic (EM) loop–loop observations in ways that cannot be replicated by conductive, nonsusceptible earth models. The most distinctive effects are negative in‐phase values at low frequencies. Inverting data contaminated by susceptibility effects for conductivity alone can give misleading models: the observations strongly influenced by susceptibility will be underfit, and those less strongly influenced will be overfit to compensate, leading to artifacts in the model. Simultaneous inversion for both conductivity and susceptibility enables reliable conductivity models to be constructed and can give useful information about the distribution of susceptibility in the earth. Such information complements that obtained from the inversion of static magnetic data because EM measurements are insensitive to remanent magnetization.We present an algorithm that simultaneously inverts susceptibility‐affected data for 1D conductivity and susceptibility models. The solution is obtaine...

Death Can Be Good for Your Health: Fitness Intentions as a Proximal and Distal Defense Against Mortality Salience

Abstract: Although terror management theory has stimulated a wide body of research, no research to date has demonstrated empirically that intentions to engage in health-oriented behavior can function as a terror management defense. Toward this end, the present studies examined whether increased fitness intentions could be used as both a direct defense against conscious concerns with death, but also as an indirect defense against unconscious death concerns among individuals for whom fitness is important to their self-esteem. In Study 1, both high and low fitness esteem participants responded to reminders of mortality with immediate exaggerated fitness intentions, relative to controls. Study 2 replicated this effect, but also found that a similar increase in fitness intentions only emerged following a delay when fitness was important to the individuals’ self-esteem. Discussion focuses on the implications for different types of psychological defense on heath-related behavior.

Culture and National Conditions Facilitating Entrepreneurial Start-ups

Abstract: Culture shapes institutional practices and policies facilitating or constraining the formation of new start-ups. This study assesses the extent to which cultural parameters and economic conditions support the development of new business start-ups in 44 nations. Cultural and economic variables provided unique contributions in predicting a profile of environmental conditions (ease of obtaining financing for new ventures, administrative burdens, legal infrastructure, and labor flexibility) favoring entrepreneurship in different nations.

Institutional theory of police: a review of the state of the art

Abstract: One of the important developments in police theory and research is the recognition of the institutional contexts in which departments participate. A body of theory, organized under the rubric of the “theory of institutionalized organizations”, provides a theoretical framework for the conceptualization and empirical assessment of policing contexts and their relationship to police organizational structures and practices. The first part of this paper provides an overview of institutional theory and reviews writings on the application of institutional theory to the police. The second section reviews research conducted on institutional theory across the field of criminal justice. The third part contrasts the competing notions of institutions and utility in institutional theory, and locates police organizations within Giddens’ model of human agency.

Neogene Carbonate Burial in the Pacific Ocean

Abstract: [1] I have compiled CaCO3 mass accumulation rates (MARs) for the period 0–25 Ma for 144 Deep Sea Drilling Project and Ocean Drilling Program drill sites in the Pacific in order to investigate the history of CaCO3 burial in the world's largest ocean basin. This is the first synthesis of data since the beginning of the Ocean Drilling Program. Sedimentation rates, CaCO3 contents, and bulk density were estimated for 0.5 Myr time intervals from 0 to 14 Ma and for 1 Myr time intervals from 14 to 25 Ma using mostly data from Initial Reports volumes. There is surprisingly little coherence between CaCO3 MAR time series from different Pacific regions, although regional patterns exist. A transition from high to low CaCO3 MAR from 23–20 Ma is the only event common to the entire Pacific Ocean. This event is found worldwide. The most likely cause of lowered pelagic carbonate burial is a rising sea-level trend in the early Miocene. The central and eastern equatorial Pacific is the only region with adequate drill site coverage to study carbonate compensation depth (CCD) changes in detail for the entire Neogene. The latitude-dependent decrease in CaCO3 production away from the equator is an important defining factor of the regional CCD, which shallows away from the equatorial region. Examination of latitudinal transects across the equatorial region is a useful way to separate the effects of changes in carbonate production (“productivity”) from changes in bottom water chemistry (“dissolution”) upon carbonate burial.

From Market Driven to Market Driving: An Alternate Paradigm for Marketing in High Technology Industries

Abstract: Although useful, the currently dominant marketing philosophies reveal themselves to be inadequate for addressing issues and problems specific to high-tech industries and products. This study proposes “market driving” as a new paradigm for marketing high-technology products and innovations. Based on an extensive review of the extant literature (and input from leading marketing scholars), a broad-based definition of the market driving approach is developed, and compared to existing paradigms of market driven activity, customer leading and market pioneering. The suitability of the market driving paradigm in addressing the unique characteristics of high technology industries is discussed.

Strategic use of bundling for reducing consumers' perceived risk associated with the purchase of new high-tech products

Abstract: Consumers’ perceived risk is a significant barrier to the adoption of new high-tech products. Based on a review of the marketing, consumer behavior and psychology literatures, a theoretical framework is developed here that suggests how bundling a new high-tech product with an existing technology could help reduce consumers’ perceived risk associated with the purchase of the new high-tech product. This manuscript also explores what factors influence consumers’ risk perception when a product bundle is available. Managers might use this framework to develop bundling strategies for high-tech products, and to understand what factors make such bundles more attractive.

School Shootings and the Man-Bites-Dog Criterion of Newsworthiness:

Abstract: School shootings have received considerable media attention in recent years. These widely publicized crimes have provoked fear among parents, school staff, and the public at large despite data indicating that school violence has not significantly increased. This article examines the ways in which school shootings are depicted in the media and contrasts these images with official sources of juvenile crime data. The findings indicate that media reports of school shootings lead to grossly distorted perceptions of the potential for victimization. Recommendations are offered to help provide more accurate and balanced coverage of these tragic events.

The Effect of Gender Role Orientation on Same- and Cross-Sex Friendship Formation

Abstract: The purpose of this study was to investigate the impact of gender role orientation on factors related to same- and cross-sex friendship formation. Participants (N = 278) completed a version of the Bem Sex Role Inventory. Each participant listed their closest friends, the sex of each friend, and the closeness level of each relationship. They also indicated whether they prefer same- or cross-sex friendship. The results suggest that gender role orientation affects inclination for cross-sex friendship, particularly the relative frequency of cross-sex friendship. Feminine men had a significantly higher proportion of cross-sex friendships than did masculine men, and masculine women had a significantly higher proportion of cross-sex friendships than did feminine women. A significant number of participants indicated that they did not prefer one sex or the other for friendship. Gender role orientation had no impact on levels of closeness in either same- or cross-sex friendship.

Towards an understanding of integrity test similarities and differences: an item‐level analysis of seven tests

Abstract: A judgmental sort of 798 items from 7 paper-and-pencil integrity tests produced 23 thematic composites. Patterns of correlations between these composites and the 7 integrity measures and 2 Big Five measures shed light on similarities and differences between different integrity tests. Principal components analysis of 23 composites indicated 4 principal components that further illuminate the content domain of integrity tests. The relationships between 4 integrity principal components and integrity test scores as well as measures of the Big Five dimensions of personality are reported. The findings suggest that integrity tests can differ in their emphasis on various thematic composites, and, yet, be very similar in terms of their standing on the 4 integrity principal components. Different integrity tests can be quite different in terms of surface content, and, yet, assess the same underlying constructs.

Anterior Cruciate Ligament Injury in Paediatric and Adolescent Patients A Review of Basic Science and Clinical Research

Abstract: Anterior cruciate ligament (ACL) injuries are recognised with greater frequency in children and adolescents. Non-operative treatment of ACL injuries in children may lead to knee instability and secondary injuries, especially in those who return to sports. ACL reconstruction is controversial in skeletally immature patients because of potential damage to the proximal tibial and distal femoral physes, which may lead to premature arrest and/or leg length discrepancies. This paper reviews studies of ACL injuries in children and adolescents, and examines basic science and clinical studies concerning physeal arrest secondary to ACL reconstruction tunnels. Some animal studies support the conclusion that ACL reconstructions in children have the potential to cause growth disturbances, and there are reports of growth plate complications due to ACL reconstruction in skeletally immature patients. There is evidence that ACL reconstruction can be performed in select skeletally immature patients, but the risk of growth plate complications must be considered.

Recruitment of healthy adults into a study of overnight sleep monitoring in the home: experience of the Sleep Heart Health Study.

Abstract: The Sleep Heart Health Study (SHHS) is a prospective cohort study using participants from several ongoing cardiovascular and respiratory disease research projects to investigate the relationship between sleep-disordered breathing and cardiovascular disease. This study design required unusual and different recruiting techniques to meet the study’s enrollment goal of between 6000 and 6600 participants. Individuals were recruited to undergo an overnight home polysomnogram, completion of several questionnaires, and collection of a small amount of physical examination data. This article describes the methods used to recruit these participants and how these procedures influenced the final participation rate and the representativeness of SHHS to its parent cohorts. Of 30,773 people eligible for recruitment into SHHS, attempts were made to enroll 11,145 (36%). Of those contacted, 6441 ultimately agreed to participate (58%). Recruitment rates (38 to 91%) varied among sites. SHHS participants were slightly younger (63.0 vs. 65.0 years, p < 0.001), had more years of education (14.1 vs. 13.7, p < 0.001), more likely to snore (34% vs. 23%, p < 0.001), had higher Epworth sleepiness scores (7.7 vs. 6.5, p < 0.001), slightly higher higher systolic and diastolic blood pressures (127.6/73.9 vs. 127.2/72.1, p < 0.001 for diastolic only), and a slightly higher body mass index (BMI) (28.5 vs. 27.5, p < 0.001). We conclude that it is feasible to recruit existing participants from one large-scale epidemiologic study into another with a high degree of success. However, the characteristics of the new cohort may vary in several respects from their original cohorts and therefore interpretation of study results will have to consider these differences.

An Extreme Rainfall/Runoff Event in Arctic Alaska

Abstract: Rainfall-generated floods in the Arctic are rare and seldom documented. The authors were fortunate in July 1999 to monitor such a flood on the Upper Kuparuk River in response to a 50-h duration rainfall event that produced a watershed average in excess of 80 mm. Atmospheric conditions prevailed that allowed moist air to move northward over areas of little or no vertical relief from the North Pacific Ocean to the Arctic Ocean. Cyclogenesis occurred along the quasi-stationary front separating maritime and continental air masses along the arctic coast. This low-pressure system propagated southward (inland) over the 142-km2 headwater basin of the Kuparuk River in the northern foothills of the Brooks Range; a treeless area underlain by continuous permafrost. This research catchment was instrumented with a stream gauging station, two major and six minor meteorological stations, for a total of eight shielded rain gauges. The peak instantaneous flow was estimated at 100 m3 s−1 and was about 3 times great...

The effect of transdermal corticosterone application on plasma corticosterone levels in pregnant Lacerta vivipara.

Abstract: Relationships between hormones and behaviour can be explored by altering endogenous hormone levels, often through implantation of silastic tubing or osmotic pumps filled with a hormone or its agonists or antagonists. However, organisms in sensitive life-history stages (such as pregnancy) may be adversely affected by the surgical procedures associated with these manipulations, necessitating use of non-invasive techniques. We demonstrate that the application of a sesame oil-corticosterone mixture to the skin of pregnant female common lizards (Lacerta vivipara) elevates plasma levels of the hormone. Pregnant female L. vivipara were captured and treated daily for 1-20 days with the sesame oil-corticosterone mixture (experimental group) or with vehicle only (control group). Blood samples were collected and analyzed for corticosterone by radioimmunoassay. Baseline plasma corticosterone levels were elevated within 1 h in the experimental group. Similar levels ( approximately 145 ng/ml) were found over the subsequent 2 days, and by day 5 had risen significantly higher ( approximately 281.9 ng/ml), where they remained for the duration of the experiment. These increases are comparable to those found in other species using related techniques. No significant changes in plasma corticosterone levels occurred in the control group. Finally, corticosterone levels also were determined for untreated females that were captured, held overnight, sampled, and released to access to the natural range of basal corticosterone levels. Basal plasma levels of corticosterone in pregnant females varied among individuals independently of female body size or corpulence.

Inhibition of Actin Polymerization by Peroxynitrite Modulates Neutrophil Functional Responses

Abstract: Peroxynitrite, a potent oxidant generated in inflammatory tissues, can nitrate tyrosine residues on a variety of proteins. Based on previous studies suggesting that actin might be a potential target for peroxynitrite-mediated nitration in neutrophils, we investigated the effects of peroxynitrite on actin function. We show here that peroxynitrite and the peroxynitrite generator (SIN-1) modified actin in a concentration-dependent manner, resulting in an inhibition of globular-actin polymerization and filamentous-actin depolymerization in vitro. The effects of peroxynitrite were inhibited by the pyrrolopyrimidine antioxidant PNU-101033E, which has been shown previously to specifically block peroxynitrite-mediated tyrosine nitration. Furthermore, spectrophotometric and immunoblot analysis of peroxynitrite-treated actin demonstrated a concentration-dependent increase in nitrotyrosine, which was also blocked by PNU-101033E. Activation of neutrophils in the presence of a nitric oxide donor (S-nitroso-N-acetylpenicillamine) resulted in nitration of exogenously added actin. Nitrated actin was also found in peroxynitrite-treated neutrophils, suggesting that actin may be an important intracellular target during inflammation. To investigate this issue, we analyzed the effect of peroxynitrite treatment on a number of actin-dependent neutrophil processes. Indeed, neutrophil actin polymerization, migration, phagocytosis, and respiratory burst activity were all inhibited by SIN-1 treatment in a concentration-dependent manner. Therefore, the ability of peroxynitrite to inhibit actin dynamics has a significant effect on actin-dependent, cellular processes in phagocytic cells and may modulate their host defense function.

Back Pain in Former Intercollegiate Rowers A Long-term Follow-up Study

Abstract: Background: Research has shown that 32% of intercollegiate rowers develop back pain during their college career.Hypothesis: Rowers who develop back pain in college are more likely than the general population to have back pain later in life.Study Design: Survey.Methods: Surveys from 1561 former intercollegiate rowing athletes were analyzed. Subjects who completed the surveys had graduated from college at a mean and median of 13 years previously, with a range of 0 to 20 years between graduation and completion of the survey. The survey was designed to determine the presence of back pain and its severity before, during, and after intercollegiate rowing. Back pain was defined as pain that lasted at least 1 week.Results: Age was a significant predictor of back pain after college. Nevertheless, the lifetime prevalence of back pain in former intercollegiate rowers was no different from that of the general population (51.4% versus 60% to 80%). However, rowers who developed back pain in college had more subsequent ...

Determinants of Money Management Behavior

Abstract: Financial debt continues to rise, especially among college students, indicating a need for behavioral research to develop more effective money-management interventions. This study examined social psychological variables relevant to money management decision making among college students. Attitude, affect, perceived ability, and past experience were found to influence money-management behavior (i.e., maintaining a budget). We also examined an attitude model of money management and found 9 variables (e.g., normative influence, perceived barrier, perceived control) that determined attitudes toward maintaining a budget. The relevance of our findings to debt prevention is discussed.

Applying the "Congruence" Principle of Bloom's Taxonomy to Designing Online Instruction.

Abstract: Bloom and his colleagues developed the laxonomy of educaliona! objcclivcs in 1936, and 45 years later a group of psychologists and educatoi^s irvised the one-dimensional taxonomy lo a two-dimensional Cixonomy, The developers offhi; laxonomy lhcori/.i:d Ihal ihc taxonomy ofcducalional objectives could be u.'^ed wilh any suhjcci matter and for any levels of learners. However, lillie has been written aboiii how ihe laxonomy can be lilfeeiivcly used in designing asynchronously-delivcred online inslmetion. We have found Ihat Ihe laxonomy is an efleclive guideline for designing graduale-lcvel online inslmclion, because il helped us maintain ihe congruence among inslmclional components. In this article, we present a case study that explains how the use ol the taxonomy of educational objectives was instrumental in the developinenl of graduate-level online insiniction.
