Many believe that project complexity reduces project management performance. However, so far research has failed to establish this causal relationship conclusively. We extend research on project ...complexity by introducing the concept of team-level absorptive capacity and by studying its role as mediator between project complexity and project management success. Applying structural equation modelling to a sample of 285 respondents, we find an unequivocal, direct and positive statistical association between project complexity and delays and overspending. Further, we show that team-level absorptive capacity is critical for successful project management, but also that absorptive capacity can only partially offset the harmful impact of project complexity. Beyond adding to project management theory, the paper contributes to the wider management literature. We establish complexity as an antecedent of absorptive capacity and demonstrate how each dimension of absorptive capacity has unique determinants and outcomes.
•Project complexity increases the risk of unscheduled delays.•Project complexity makes cost overruns more likely.•Team-level absorptive capacity mitigates delays and overspending.•Project-team capacities cannot fully offset the effect of project complexity.
Thermal conditions in the nest affect the development of sea turtle clutches, with high temperatures potentially reducing reproductive success and the quality of hatchlings. In a warming climate, ...increasing temperatures could become a threat to sea turtles in many locations. This has prompted the implementation or recommendation of climate mitigation strategies in nests that incubate in hatchery conditions. Here, olive ridley turtle (
Lepidochelys olivacea
) clutches relocated to a beach hatchery in Playa Grande, Costa Rica (10° 20 N, 85° 51 W) were used to study the effect of temperature on hatching success and hatchling size. Data from 5 nesting seasons (2017/18 to 2022/23, excluding 2020/21) were tested to determine the effect of mean incubation temperature by thirds of development, as well as over the whole incubation period. Hatching success was lower at low and high temperatures and higher at intermediate ones during the second and last thirds of development. Optimal mean temperature ranges were 29–32 °C and 32–35 °C across the second and last thirds of development respectively, and 30–32.5 °C during the whole incubation period. There was no statistically significant effect of temperature on hatching success during the first third of development. High temperature resulted in shorter carapace width but did not statistically affect mass or carapace length. The temperature effect on carapace width occurred in all thirds of development. Studying temperature effects on target species nests at the local level, throughout incubation, and over multiple years is important for applying climate mitigation strategies properly.
Abstract
Female density and distribution are dependent on resource phenology and female availability strongly influences male mating behaviour and success. When a male adopts a ‘resource defence’ ...tactic, his reproductive success depends on the location and attractiveness of his territory. Environmental factors associated with territory quality are expected to influence mating success, for example, through territory features or male–male competition. In a protected population of a mountain‐dwelling polygynous herbivore, the Alpine chamois
Rupicapra r. rupicapra
, we investigated the relationships among mating opportunities, some environmental variables (snow depth, topographic features and size of territories) and male intra‐sexual competition for mating. We recorded the mating behaviour and territory size of 15 GPS‐GSM radio‐tagged territorial males, during five rutting seasons (early November to early December:
N
= 8 individuals in 2011,
N
= 9 in 2012,
N
= 8 in 2015,
N
= 11 in 2016,
N
= 7 in 2017; 80% of them were observed for more than one mating season) and related them to snow depth and topography of territories. In ruts with deep snow cover, territorial males had smaller territories and higher number of mating opportunities than in ruts with lower snow cover. Smaller territories showed the highest values of terrain roughness, in turn with little or no snow cover in the mating season, and were visited by a greater number of females, than larger territories. Number of wins was positively influenced by snow depth and negatively related to the frequency of aggressions. The frequency of male–male aggressive interactions was greater during ruts with deep snow cover and for males with territories at higher elevations; additionally, it was negatively related to interactions won. Thus, snow depth, which influences resource distribution and female movements, is confirmed as a strong determinant of male mating opportunities and mating behaviour.
PurposeThe digital transformation under Industry 4.0 is complex and resource-intensive, making a strategic digitalization guideline vital to small and medium-sized enterprises' success in the ...Industry 4.0 transition. The present study aims to provide manufacturing small and medium-sized enterprises (SMEs) with a guideline for digital transformation success under Industry 4.0.Design/methodology/approachThe study first performed a content-centric literature review to identify digital transformation success determinants. The study further implemented interpretive structural modeling to extract the order at which the success determinants should be present to facilitate the SMEs’ digital transformation success optimally. The interpretive model and interpretive logic knowledge base matrix were also used for developing the digital transformation guideline.FindingsEleven success determinants are vital to SMEs’ digital transformation efforts. For example, results revealed that external support for digitalization is the first step in ensuring digital transformation success among SMEs, while operations technology readiness is the most inaccessible success determinant.Research limitations/implicationsThe study highlights the degree of importance of the 11 success determinants identified, which magnifies each determinant's strategic priority based on its driving power and dependence power. Theorizing the dependent variable of “digital transformation success” and quantitatively measuring the extent to which each success determinant contributes to explaining “digital transformation success” offers an exciting opportunity for future research.Practical implicationsDigital transformation success phenomenon within the Industry 4.0 context is significantly different from the digitalization success concept within the traditional literature. The digital transformation under Industry 4.0 is immensely resource-intensive and complex. Smaller manufacturers must have specific capabilities such as change management and digitalization strategic planning capability to reach a certain degree of information, digital, operations and cyber maturity.Originality/valueThe digital transformation success guide developed in the study describes each success determinants' functionality in relation to other determinants and explains how they might contribute to the digital transformation success within the manufacturing sector. This guide enables smaller manufacturers to better understand the concept of manufacturing digital transformation under Industry 4.0 and devise robust strategies to steer their digital transformation process effectively.
We investigated the home culture effect with respect to students’ perceptions about themselves and their instructors. This study was concerned with the cross-cultural analysis of Iranian and Iraqi ...students’ perceptions of teacher success, credibility, and stroke variables. Willingness to Attend Classes (WTAC) was evaluated. Two-hundred-seventy-six Iranian and 150 Iraqi English as a Foreign Language (EFL) university students participated in the study. Results of the multi-group modeling showed measurement invariance, both metric and scalar, across the groups. Afterwards, descriptive statistics indicated that both groups held high perceptions of their own WTAC and their teachers’ stroke, effectiveness, and credibility. Next, correlational results indicated that the sub-components of perceived teacher credibility, stroke, and success variables were significantly and positively associated with Iranian and Iraqi students’ WTAC. These outputs were approved in the SEM results, and the hypothesized relations between the variables were approved; perceived teacher stroke, success, and credibility factors were positive significant predictors of Iranian and Iraqi students’ WTAC. On the whole, these findings provided empirical backing for the theoretically-rich claim that students’ home culture background significantly predicts the way their belief systems are shaped and reshaped. Hence, teacher educators should be concerned with training teachers who not only effectively teach language to the students but also fulfill students’ expectations of a successful teacher who is able to provide culturally-appropriate quality communication in the classroom and build a relationship of trust between him/herself and the students with the ultimate aim of enhancing student-related academic outcomes.
Several success criteria (SC) and categorization models have been introduced and studied in the previous decades to address the issue of project success. However, most of these models have failed to ...align success criteria with company's success in the long-term. This paper aims at proposing a framework to categorize project success for building projects in Malaysia from the contractors' perspective. The proposed framework incorporates criteria that align the project efforts with both short and long-term goals of the companies; moreover provide an appropriate judgment of success at all stages of the project. If construction managers can judge the probability of success, they would be able to evaluate the overall relative strength of each project, and identify problems on current projects to direct them toward success.
Based on the available literature, thirteen success criteria were found to be significantly and substantially related to building projects success. To develop the SC categorization framework, 151 participants, who are involved in building construction, were invited through a postal and e-mails survey to generate priorities of these criteria. The results of this study indicated that a categorization scheme for success criteria for building projects should include the categories of project management success, product success, along with market success. The findings of this study can further help future researchers seeking solutions in the challenges relating to improvement of building projects implementation and enhancement of project success.
In polygynous species, male reproductive success is often determined by their ability to dominate female harems. Harem‐holders sire a disproportionate number of offspring. Male dominance tends to ...correlate with age, but intense competition and early male mortality limit most males from achieving high social status. To maximize reproductive success despite low rank, offspring sex ratio adjustment may have evolved, favoring the sex with higher fitness. If traits influencing dominance are heritable and confer reproductive advantages, we expect fathers with higher reproductive success to produce more sons, as they are more likely to become dominant. In contrast, subordinate males with lower success may benefit from siring more daughters. We tested this hypothesis on a colony of southern elephant seals breeding on the Kerguelen Archipelago. We used genetic markers to link the paternity of 540 pups to 58 breeding males. We found that the probability of siring a son increases from 43% to 54% with paternal relative reproductive success, supporting the offspring sex ratio adjustment hypothesis. Given that various factors influence sex ratio in a population, future studies should tease apart these ecological processes (e.g., paternal dominance, maternal condition, local density, or adult sex ratio) and investigate how they interact with each other.
Abstract only Introduction Endovascular therapy (EVT) is the standard‐of‐care for large vessel occlusion stroke; however, timely access to treatment is still limited for a large proportion of the ...population. Telerobotic EVT has the potential to decrease time to treatment and expand existing networks of care to more rural populations. It is currently unclear how its implementation would impact existing stroke networks. Methods Conditional probability models were generated to predict the probability of excellent outcome (modified Rankin Scale 0–1 at 90 days post stroke) for patients with suspected large vessel occlusion (LVO). A baseline stroke network was created for California using existing intravenous thrombolysis (IVT) centers and comprehensive stroke centers (CSCs) capable of IVT and EVT. Optimal transport decisions and catchment areas were generated for the baseline model and three hypothetical scenarios through conversion of IVT centers at various distances from a CSC into centers capable of Telerobotic EVT i.e. hospitals ≥ 15 and < 50 miles from a CSC were converted (Scenario 1), ≥ 50 and < 100 miles (Scenario 2), and ≥ 100 miles (Scenario 3). Catchment areas were calculated for each scenario using varied robotic procedural delay times and success rates. Results In the baseline model, 51 hospitals were designated as CSCs and 142 hospitals were designated IVT centers. Conversion of IVT centers into Telerobotic EVT centers decreased median travel time for LVO patients in all three scenarios. The estimated number of robotically treated LVOs per year in Scenarios 1, 2, and 3 were 2172, 740, and 212, respectively. Scenario 1 (15‐50 miles) was the most sensitive to robotic time delay and success rate, but all three scenarios were more sensitive to decreases in procedural success rate compared to time delay. Conclusions Telerobotic EVT has the potential to improve care for stroke patients outside of major urban centers. Compared to procedural time delays in robotic EVT, a decrease in procedural success rate would not be well tolerated. This modeling analysis can inform system planning for the potential advent of remote EVT care.
