Integration of quantum physics theories to understand open government data (OGD) adoption by the government

PurposeThis paper aims to further the understanding of Open Government Data (OGD) adoption by the government by invoking two quantum physics theories – percolation theory and expander graph theory.Design/methodology/approachExtant research on the barriers to adoption and rollout of OGD is reviewed to drive home the research question for the present study. Both the theories are summarized, and lessons are derived therefrom for answering the research question.FindingsThe percolation theory solves the riddle of why the OGD initiatives find it difficult to seep across the hierarchical and geographical levels of any administrative division. The expander graph theory builds the understanding of the need for having networking among and within the key government personnel for bolstering the motivation and capacity building of the operational personnel linked with the OGD initiative. The theoretical understanding also aids in the implementation and institutionalization of OGD in general.Originality/valueIntersectionality of domains for conducting research on any theme is always a need. Given the fact that there are innumerable challenges regarding the adoption of OGD by the governments across the world, the application of the two theories of quantum physics might solve the quandary in a befitting way.

Fatty acid profiles and stable isotope composition of Antarctic macroalgae: a baseline for a combined biomarker approach in food web studies

AbstractThe Western Antarctic Peninsula supports a diverse assemblage of > 100 described macroalgal species that contribute to the base of coastal food webs, but their contribution to local nearshore food webs is still uncertain across larger spatial scales. The analysis of biomarkers, specifically fatty acids and stable isotopes, offers a tool to clarify the trophic role of Antarctic macroalgae. The aim of this study was to describe the fatty acid profiles and stable isotope values of 31 algal species from three divisions (Chlorophyta—1, Ochrophyta—8, Rhodophyta—22) collected at the same sites for both biomarkers. Of these, 13 species had no previously published fatty acid profiles. Most species were rich in polyunsaturated fatty acids (PUFAs), suggesting they are highly nutritious and could be a resource of essential fatty acids for consumers. This was specifically noticeable in the overall low PUFA ratio (∑ω6/∑ω3 ratio), with low ratios being an indicator of high nutritional quality for consumers. Fatty acid profiles of macroalgae grouped strongly by phylogeny (at the levels of division, order, and family), while stable isotope groupings were more driven by the physiological properties of the species. Specifically, some closely related red algal species exhibited very different stable isotope values based on their carbon concentrating mechanisms, with highly 13C-depleted values in several Rhodophyta species. The fact that the two biomarker approaches created different groupings of Antarctic macroalgae collected at the same locations emphasizes that their combined application can be a powerful tool in Antarctic coastal food web studies.

Functional characterization of D-type cyclins involved in cell division in rice

BackgroundD-type cyclins (CYCD) regulate the cell cycle G1/S transition and are thus closely involved in cell cycle progression. However, little is known about their functions in rice.ResultsWe identified 14 CYCD genes in the rice genome and confirmed the presence of characteristic cyclin domains in each. The expression of the OsCYCD genes in different tissues was investigated. Most OsCYCD genes were expressed at least in one of the analyzed tissues, with varying degrees of expression. Ten OsCYCD proteins could interact with both retinoblastoma-related protein (RBR) and A-type cyclin-dependent kinases (CDKA) forming holistic complexes, while OsCYCD3;1, OsCYCD6;1, and OsCYCD7;1 bound only one component, and OsCYCD4;2 bound to neither protein. Interestingly, all OsCYCD genes except OsCYCD7;1, were able to induce tobacco pavement cells to re-enter mitosis with different efficiencies. Transgenic rice plants overexpressing OsCYCD2;2, OsCYCD6;1, and OsCYCD7;1 (which induced cell division in tobacco with high-, low-, and zero-efficiency, respectively) were created. Higher levels of cell division were observed in both the stomatal lineage and epidermal cells of the OsCYCD2;2- and OsCYCD6;1-overexpressing plants, with lower levels seen in OsCYCD7;1-overexpressing plants.ConclusionsThe distinct expression patterns and varying effects on the cell cycle suggest different functions for the various OsCYCD proteins. Our findings will enhance understanding of the CYCD family in rice and provide a preliminary foundation for the future functional verification of these genes.

Polarizing Online Elite Rhetoric at the Federal, State, and Local Level During the COVID-19 Pandemic

Times of national and international crisis are often unifying events which lower levels of division within the public and between political elites. Yet, COVID-19 pandemic responses in the United States have been viewed as markedly polarized. Using a comprehensive dataset of over four million social media posts sent by local, state, and federal level political officials between January 2020 and September 2022, this paper explores the extent to which the COVID-19 pandemic was a rhetorically unifying or divisive event, and whether rhetorical responses differed across levels of government. The results show that federal level officials were less likely to message about COVID-19 and were more likely to do so in a polarizing fashion compared to state and local officials. Temporally, in the early stages of the pandemic there was indeed a collective rhetorical de-polarization across all levels of government. However, as the pandemic progressed, COVID-related messaging became more polarizing, especially among Republicans. Evidence also emerges of dynamic responsiveness from elected officials, with relativeness attentiveness to COVID increasing and polarizing rhetoric decreasing during time periods when local case counts were relatively high. These findings suggest that rhetorical unity is still possible, even in times of high political polarization, but that this unity is also short-lived and tempered by political and electoral considerations.

Adult neurogenesis does not explain the extensive post-eclosion growth of Heliconius mushroom bodies.

Among butterflies, Heliconius have a unique behavioural profile, being the sole genus to actively feed on pollen. Heliconius learn the location of pollen resources, and have enhanced visual memories and expanded mushroom bodies, an insect learning and memory centre, relative to related genera. These structures also show extensive post-eclosion growth and developmental sensitivity to environmental conditions. However, whether this reflects plasticity in neurite growth, or an extension of neurogenesis into the adult stage, is unknown. Adult neurogenesis has been described in some Lepidoptera, and could provide one route to the increased neuron number observed in Heliconius. Here, we compare volumetric changes in the mushroom bodies of freshly eclosed and aged Heliconius erato and Dryas iulia, and estimate the number of intrinsic mushroom body neurons using a new and validated automated method to count nuclei. Despite extensive volumetric variation associated with age, our data show that neuron number is remarkably constant in both species, suggesting a lack of adult neurogenesis in the mushroom bodies. We support this conclusion with assays of mitotic cells, which reveal very low levels of post-eclosion cell division. Our analyses provide an insight into the evolution of neural plasticity, and can serve as a basis for continued exploration of the potential mechanisms behind brain development and maturation.

Usefulness of knowledge in anatomy of the internal iliac artery in its ligation during life-threatening pelvic haemorrhages

Introduction: Post-Partum haemorrhage is a significant cause of maternal mortality. Bilateral internal iliac artery ligation is a life-saving procedure to control massive obstetric and gynaecological haemorrhages. Bilateral internal iliac artery ligation results in toning down the pulsatility making the arterial flow a slow venous flow encouraging the clot formation of the damaged pelvic vessels. This study assesses the retroperitoneal anatomy and regional variations of the internal iliac artery.Methods: The study was based on examining 45 pelvic halves (23 right sides and 22 left sides), which were dissected during the gross anatomy laboratory at the faculty of medicine, Ragama, University of Kelaniya, from 2020 -2023. There were all adult pelvises. The internal iliac artery and its major branches were carefully dissected and examined. Adachi classification was used to classify the distribution pattern of the internal iliac artery. The study was done on the donated cadavers, and the nature of the study did not warrant any special ethical clearance. No conflict of interest.Results: No anatomical deviation has been noted with regard to the levels of division of aorta, common iliac artery, the division into internal and external iliac arteries and the division of anterior and posterior branches of the internal iliac artery from that of classical anatomical literature. It was also noted that there had been no significant deviation of anatomical relations with regard to the structures as described in the internal lilac artery in our study. In our study, Type Ia was found in 35/45 (78%) of the specimens, Type IIa in 3/45 (6%), Type III in 7 (16%), and no specimens were found with Type IV and. Type V.Conclusion: Our study showed no significant anomalies of the pelvic anatomical structural relations to the internal iliac artery. The type Ia branching pattern was found to be the commonest.

An empirical analysis of economic growth in countries exposed to coastal risks: Implications for their ecosystems

Using a novel database on countries exposed to coastal risks (CR), this paper estimates an augmented neoclassical growth model that encompasses eight other new growth models. To account for uncertainty related to the number of models and choice of growth determinant proxies, we use a Bayesian averaging of classical estimates (BACE) approach. A preliminary examination of the data reveals that a country that faces coastal risks is likely to be a former British colony characterized by a common law legal framework, a parliamentary political system, a high degree of international trade openness, little language and ethnic fractionalization, a low level of public sector corruption, and a high rate of fertility. The BACE-based model selection procedure shows that, in CR countries, the growth determinant proxies typically used in the neoclassical, macroeconomic policy, natural resources, and institutions theories are significantly correlated with growth. These results suggest two implications related to these countries’ coastal ecosystems. First, because they are heavily dependent on natural resources and have high fertility rates, these countries might seek short-term economic gains at the expense of deterioration in their ecosystems. Second, these countries’ good institutions and low levels of ethnic division might be conducive to sustainable management of these ecosystems.

THE BILATERAL HIGH DIVISION OF THE SCIATIC NERVE IN THE PELVIS

The sciatic nerve is the thickest nerve of the body.1 It leaves the pelvis below the piriformis via the greater sciatic foramen and descends between the ischial tuberosity and greater trochanter in the back of the thigh, dividing into the tibial and common peroneal nerves proximal to the knee however, the level of bifurcation can be variable.2The levels of division of the sciatic nerve are important in anaesthesia, orthopaedics, rehabilitation, and neurology.3The study was done by dissection of forty-two human adult lower limb specimens, irrespective of sex from the Department of Anatomy, Indira Gandhi Medical College, Shimla, Himachal Pradesh, India. During dissection, 02(4.8%) specimens out of 42 specimens showed high division, 28(66.6%) specimens showed intermediate, and 12 (28.6%) specimens showed low division of the sciatic nerve.The bilateral highdivision of the sciatic nerve is a rare variation. Knowledge about the level of division of the sciatic nerve is important for clinicians and surgeons.

As part of the development of improving the methods of integrated monitoring of mudslides, a software shell of the electronic information resource «Mudflow Phenomena Database» (DB) was created. The developed database covers the issues of organizing the accounting of data on mudflow events based on the materials of complex and operational (space, ground route, etc.) monitoring of mudflow basins, as well as archival data for each of them. The purpose of this database is to provide an up-to-date information basis for assessing the current spatial and temporal changes in monitoring objects of mudflow basins, based on the results of analytical study of the replenished data. The information basis consists of information that allows us to assess the conditions of occurrence of mudflow processes in the region, their type, genesis, volume of the solid component of the mudflow, frequency, intensity, basic morphometric indicators of mudflow basins, etc. The analysis of the materials presented in the database makes it possible to identify the scale, danger, main features and patterns of the spread and development of mudflow activity. The database of mudslides, depending on the structure, content and form of search queries, can be compiled for different hierarchical levels of geographical, territorial and administrative division of the region and mudflow basins. The first part of the article describes the structure of the input information, justifies the choice of parameters to be taken into account.

Analysis of Critical Factors for the Entrepreneurship in Industries of the Future Based on DEMATEL-ISM Approach

In the face of the fourth industrial revolution (Industry 4.0 era), in order to cope with the various crises that may come, countries around the world are accelerating the research and development of cutting-edge technologies and promoting and deploying the Industries of the Future in order to seize the high ground in the new round of strategic competition in science and technology. Therefore, entrepreneurship in Industries of the Future has become an urgent problem for governments and enterprises to solve. Entrepreneurship in Industries of the Future is a systematic project with uncertainties, which is dynamically influenced by many factors and has different levels of division among them. Inspired by the form of Porter’s diamond model, this paper constructs a diamond model of the driving mechanism of entrepreneurship in Industries of the Future. Using the DEMATEL-ISM analysis method, each critical factor and influence mechanism of entrepreneurship in Industries of the Future is explored, and a multi-level structural model is established. The study found eight critical factors affecting entrepreneurship in Industries of the Future, among which technology, creation, need, and aspiration are the critical factors, and relevant enterprises and governments should prioritize these influencing factors and deal with them.

Investigating The Impact Of Covid-19 On Perceived Stress Levels Of Division II Student-athletes

PURPOSE: To assess perceived stress levels of Division II student-athletes (SAs) following the interruption of their training and competition due to the COVID-19 pandemic. It was hypothesized that perceived stress during the pandemic would be higher in COVID positive SAs compared to quarantined SAs and those SAs who were not diagnosed/ not quarantined. METHODS: Division II SAs (n = 99) completed an online, self-reported demographics questionnaire, COVID-19 questionnaire, and the Perceived Stress Scale (PSS) at one time point. The 10-item PSS measures the degree to which situations in one’s life are appraised as stressful (For example: How often have you been upset because of something that happened unexpectedly? 0 = Never to 4 = Very Often). SAs were placed into three groups based on their COVID-19 status: tested positive with or without symptoms (n = 41); quarantined due to close contact (n = 34); or no direct interaction with COVID-19 (n = 24). One-way ANOVA was used to determine the differences in perceived stress levels among SA groups. An alpha level of p ≤ 0.05 was set for statistical significance. RESULTS: PSS scores were not statistically different (p > 0.05) between positive diagnosis of COVID-19 (19 ± 7), quarantined due to close contact (19 ± 7), and not diagnosed nor quarantined (22 ± 8) SA groups. CONCLUSIONS: The results refuted the hypothesis that SAs who tested positive for COVID-19 reported higher perceived stress levels than those who were undiagnosed-quarantined or those neither diagnosed nor quarantined. Interestingly, the data demonstrated that SAs who were not diagnosed nor quarantined due to COVID-19 demonstrated similar perceived stress to those SAs who tested positive for COVID-19. Per this finding, it was thought that SAs not exposed to COVID-19 or having to quarantine may have experienced higher stress levels due to the fear of contracting the virus. In addition, these SAs may also have had elevated stress due to their teammates testing positive for COVID-19 and missing competition, training, or team practice. It was unclear how the relationship between PSS scores and COVID-19 interaction may have impacted athletic performance and preparedness during the 2020-2021 athletic season.

PEMIKIRAN IBNU KHALDUN TENTANG KETENAGAKERJAAN DAN RELEVANSINYA DI INDONESIA

Ibn Khaldun's thoughts on employment and its relevance in Indonesia”, with the background of the problem, namely, the enactment of Law Number 13 of 2003, is part of the government's grand scenario to organize and negotiate common interests between employers, workers and the government. If companies have an interest in capital development, workers have an interest in increasing income, then the government secures the macro economy. Because without conducive conditions, the economy of a country will be shaken. Ibn Khaldun was a Muslim scientist who had many thoughts in various fields such as economics. In his economic sub-study on employment, which is contained in Muqadimah's book on the theory of value, division of labor and international trade, the law of supply and demand, consumption, production, money, trade cycles, public finance, and several macroeconomic discussions.
 The type of research is library research. The type of data used is primary data, namely all of Ibn Khaldun's works that discuss employment, both implied and explicit, as well as data on employment in Indonesia. While secondary data is related to formal objects and enrichment that discusses employment in Indonesia.
 From the results of the researcher's analysis, it is known that, firstly, Ibn Khaldun's rationale for the emergence of the employment system because, to meet basic personal (dharuri), secondary (hajiyyah) and tertiary (tahsinat) needs, as well as to meet the needs of many people (subjective mass), is called " tamawwul” (company). then for that humans to meet personal needs and many people have to produce en masse, the more needs, the more they produce, the more alliances (employment) arise, this is because what drives humans instinctively to work, because they work as human intermediaries to get what they want. that God created. Second, the main points of Ibn Khaldun's thoughts on employment are that the concept of thought starts from production, namely one of the factors is labor, with its elaboration; there are three levels of division of labor, namely the community, industry and international levels. Next is the demand and supply of labor, labor wages, expansion of job opportunities, competence and technology. Third, Based on these points of view, it can be concluded that Ibn Khaldun's thoughts have relevance to employment in Indonesia today. The relevance is found in the constitution or positive law of Indonesia in Article 33 of the Basic Law (UUD) article 33 and Law Number 13 of 2003 concerning employment, namely first according to Khaldun about the nature of labor as mutualism, while in the Indonesian constitution it is reflected in the Constitution. Article 33 paragraph (1). Second, work competence at the community, industrial and international levels, in Indonesian regulations is regulated in law number 13 of 2003 articles 9, 10, 11, and 12. Third, expansion of job opportunities in Indonesian regulations is regulated in law number 13 of 2003. 2003 articles 39, 40 and 41. Fourth, the salary of Khaldun's workers is the benchmark for meeting basic living needs (dharuri) while Indonesian regulations adhere to the principle of meeting the needs of a decent living (KHL).

Push or Pull? Cell Proliferation and Migration During Wound Healing

Wound healing of the skin is a complex process that is still not well-understood. Wound management is expensive for both individuals and the health system overall, and can reduce quality of life for patients. Given these significant socio-economic impacts, wound healing has long been a focus of scientific research. Recentin vivomouse studies have identified two key regions in wounded skin tissue: A non-proliferative leading edge that actively migrates into wounded space, and a proliferative hub in which cells have enhanced mitotic properties. This work uses mathematical and computational modelling to investigate the effect of changing the mechanical characteristics of cells in these two key regions. In this paper we explore what characteristics are sufficient for wound healing, particularly focusing on cell proliferation, since wounds are not able to repair successfully without sufficient levels of cell division. By considering contact inhibited proliferation, where small cells are unable to divide, we find that a quiescent region develops if the proliferative hub is able to grow over time, essentially limiting the number of cells that are able to divide. In contrast, if the size of the proliferative hub is kept below some threshold, then contact inhibition has a less significant role in wound repair. This work builds upon existing cell-based computational studies of wound healing and could be modified to investigate different stages of wound healing, impaired healing and wound treatments.

Induced effect of zinc oxide nanoparticles on human acute myeloid leukemia cell apoptosis by regulating mitochondrial division.

Zinc oxide nanoparticles (ZnO NPs) have exhibited excellent anti-tumor properties; the present study aimed to elucidate the underlying mechanism of ZnO NPs induced apoptosis in acute myeloid leukemia (AML) cells by regulating mitochondrial division. THP-1 cells, an AML cell line, were first incubated with different concentrations of ZnO NPs for 24 hr. Next, the expression of Drp-1, Bcl-2, Bax mRNA, and protein was detected, and the effects of ZnO NPs on the levels of reactive oxygen species (ROS), mitochondrial membrane potential (Δψm), apoptosis, and ATP generation in THP-1 cells were measured. Moreover, the effect of Drp-1 inhibitor Mdivi-1 and ZnO NPs on THP-1 cells was also detected. The results showed that the THP-1 cells survival rate decreased with the increment of ZnO NPs concentration and incubation time in a dose- and time-dependent manner. ZnO NPs can reduce the cell Δψm and ATP levels, induce ROS production, and increase the levels of mitochondrial division and apoptosis. In contrast, the apoptotic level was significantly reduced after intervention of Drp-1 inhibitor, suggesting that ZnO NPs can induce the apoptosis of THP-1 cells by regulating mitochondrial division. Overall, ZnO NPs may provide a new basis and idea for treating human acute myeloid leukemia in clinical practice.

Unpacking the Determinants of Outrage and Recognition in Public Discourse: Insights Across Socio-Cultural Divides, Political Systems, and Media Types

The degree to which civility norms are upheld or violated is an important criterion in evaluating the democratic quality of public debates. We investigate civility across media types, political systems, and levels of socio-cultural division, offering a comparative perspective on how these factors shape levels of civility in public debates around a key question for societies around the world: What is the proper role of religion in public life? Capturing both positive and negative forms of civility (i.e., recognition and outrage) on multiple levels of analysis, we compile and analyze an original large-scale dataset of news items published during August 2015 until July 2016 in six democracies (Australia, Germany, Lebanon, Switzerland, Turkey, and the USA) across three types of media (printed newspapers, news websites, and political blogs). We find that mediated discourse was heavier on outrage in mixed political systems (Germany and Turkey) than in ‘purely’ majoritarian and consensus systems. Public debate in deeply divided countries contained more outrage but also more recognition compared to less divided countries, with newspapers and news websites mitigating outrage discourse compared to political blogs. Blogs also emerged as less nurturing of recognition than newspapers and news websites.

Геоинформационные методы исследования пространственной неоднородности распределения доходов населения Аргентины

Argentina is a country with a very specific system of territorial division carried out for the optimization of public administration and collection of statistics. Historically developed spatial heterogeneity of socio-economic development has several specific features, as well as non-trivial factors, due to which the country is formed by a peculiar pattern of territorial inequalities. In addition to administrative divisions into provinces and departments, Argentina has a number of statistical division grids for the lower scale levels. However, the organization of the collection of statistical data for different levels of territorial division is not optimal: for a number of regions, statistical data in the public domain are practically absent, or presented in aggregated form. The aim of the research is to identify territorial differences in socio-economic development between regions and at various scale levels. The use of GIS methods made it possible to obtain the missing data for the lower level of territorial division, such as the spatial data on the administrative boundaries, population and income. The analysis of spatial autocorrelation of income distribution in Argentina can identify regions of growth as well as the influence of local factors on the territorial inequality in Argentina. The value of the coefficient of spatial autocorrelation of population income is one of the highest around the world.

Regional per capita income differences: Spatial and hierarchical dependencies

Relevance. Regional differences in per capita income are a matter of concern for many countries for many reasons, including the threat that such regional disparities pose to national security. Multiple tools and methods are used to investigate these disparities and fix them. The use of lower level aggregated data and the analysis that takes into account spatial interactions thus become particularly relevant because it allows us to reveal the diversity of interactions at the micro-level. Research objective. This study aims to determine the significance of spatial relationships at different levels of data aggregation and hierarchical dependencies in per capita income and highlight the level of administrative division (regional or municipal) that has the greatest impact on per capita income. Methods and data. The analysis relies on the data from 2,270 municipalities in 85 Russian regions. The Hierarchical Spatial Autoregressive Model (HSAR) was used to distinguish both spatial and hierarchical effects. We used three specifications of the model: with estimates of the spatial interaction on the higher level (spatial error at the regional level), on the lower level (spatial lag at the municipal level), and on both levels. Results. Spatial interactions explain the observed variation of per capita income at the municipal level data at both the higher (regional) and lower (municipal) levels but the model with the estimated spatial interaction on the higher level was better. Conclusion. Despite the importance of spatial interactions at the lower level, models that take into account spatial interactions only at the upper level may better explain the observed differences in some cases. Our findings contribute to the rather scarce research literature on spatial relationships on several levels of administrative division. We have shown that for each specific case it is important to identify not only the factors but also the spatial effects in relation to this or that level of the territorial hierarchy.

Abscisic acid mediates the reduction of petunia flower size at elevated temperatures due to reduced cell division.

Elevated temperatures suppress cell division in developing petunia buds leading to smaller flowers, mediated by ABA. Flower size is one of the most important showy traits in determining pollinator attraction, and a central factor determining the quality of floricultural products. Whereas the adverse effects of elevated temperatures on showy traits have been described in detail, its underlining mechanisms is poorly understood. Here, we investigated the physiological mechanism responsible for the reduction of flower size in petunia under elevated temperatures. We found that the early stages of flower-bud development were most sensitive to elevated temperatures, resulting in a drastic reduction of flower diameter that was almost independent of flower load. We demonstrated that the temperature-mediated flower size reduction occurred due to a shorter growth period, and a lower rate of corolla cell division. Consistently, local application of cytokinin, a phytohormone that promotes cell division, resulted in recovery of flower dimensions when grown under elevated temperatures. Hormone analysis of temperature-inhibited flower buds revealed no significant changes in levels of cytokinin, and a specific increase of abscisic acid (ABA) levels, known to inhibit cell division. Moreover, local application of ABA on flower buds caused a reduction of flower dimensions as a result of lower levels of cell division, suggesting that ABA mediates the reduction of flower size at elevated temperatures. Taken together, our results shed light on the mechanism by which elevated temperatures decrease petunia flower size, and show that temperature-mediated reduction of flower size can be alleviated by increasing the cytokinin/ABA ratio.

Investigating the Foraging, Guarding and Drifting Behaviors of Commercial Bombus terrestris

Social insects have high levels of cooperation and division of labor. In bumble bees this is partly size-based, with larger bees performing tasks outside the nest and smaller bees remaining inside, although bumble bees still display considerable behavioral plasticity. The level of specialization in tasks outside the colony, including foraging, guarding and drifting (entering a foreign colony), is currently unknown for bumble bees. This study aimed to assess division of labor between outside tasks and the degree of specialization in foraging, guarding, and switching colonies in commercially reared bumble bees placed in the field. Nine factory-bought Bombus terrestris colonies were placed on three farms in Sussex, UK, between June and August 2015. Forty workers from each colony were radio-tagged and a reader on the colony entrance recorded the date, time and bee ID as they passed. The length and frequency of foraging trips and guarding behavior were calculated, and drifting recorded. The mean (±SD) length of foraging trips was 45 ± 36 min, and the mean number of foraging trips per day was 7.75 ± 7.71. Low levels of specialization in guarding or foraging behavior were found; however, some bees appeared to guard more frequently than others, and twenty bees were categorized as guards. Five bees appeared to exhibit repeated “stealing” behavior, which may have been a specialist task. The division of labor between tasks was not size-based. It is concluded that commercial bumble bees are flexible in performing outside nest tasks and may have diverse foraging strategies including intra-specific nest robbing.
