Nursing labor supply in Iran: a survey in Shiraz public hospitals in 2022.

BACKGROUND: The labor supply of nurses, as one of the main healthcare workers, is an important issue in health human resources planning in all health systems. Finding the factors affecting it, could help policymakers to solve the shortage of nursing work supply. The present study aimed to investigating the quantity and factors affecting the nurses' labor supply in Iran. METHOD: In this cross-sectional study, a sample of 598 nurses working in public hospitals of Shiraz (Iran) were selected via proportionate stratified random sampling method. The required data was collected using a structured questionnaire which asked working hours and other related factors. To analyze the data, descriptive statistics, univariate analysis and multivariate linear regression were performed using STATA 15. The multivariate labor supply model was estimated separately for married and single nurses.  RESULTS: The average weekly working hours of nurses was 54.65 h in all medical centers and 50.28 h in the main hospital. The regression results showed that the labor supply of nurses with work experience (ß = - 0.368, P = 0.014), satisfaction with work shift arrangement (ß = - 2.473, P = 0.001), income between 60-89 million rial (ß = - 14.046, P = 0.002), income between  90-119 million rial(ß = - 12.073, P = 0.012), and working in the emergency department (ß = - 5.043, P = 0.017) had negative and significant relationship; But there was a positive and significant relationship with satisfaction of the work environment (ß = 1.86, P = 0.011), workload at work (ß = 1.951, P = 0.023) and employment status (contractual employees) (ß = 4.704, P = 0.004). CONCLUSION: The labor supply function of nurses is affected by demographic, economic and non-economic factors. The most contributing factors were related to non-economic variables. It seems that the non-financial cost and benefits related to the job as well as internal factors have more important role on the nurses' labor supply.

Strengthening of District/Taluk Level Hospitals Through Implementation of Post-graduate Medical Courses in Karnataka, India.

The World Health Organization (WHO) recommends the requirement of human resource for health (HRH) stands at 44.5 skilled health workers per 10,000 population. WHO recognizes India as one of the countries which has HRH crisis. Karnataka, a southern state in India, has the highest number of medical colleges yet faces the shortage of specialists in the public hospitals. We conducted desk review to understand the HRH crisis, particularly the medical specialists in India. Simultaneously, we conducted secondary research to explore the initiatives taken by the Government of Karnataka (GoK) to mitigate the shortage of medical specialists in the rural areas. GoK scaled up the National Board of Examination in Medical Sciences (NBEMS) postgraduate and super-speciality courses such as Diplomate of National Board (DNB), Diploma, and Doctorate of National Board (DrNB) in district hospitals (minimum 250-500 bedded) and taluk hospitals (minimum 100 bedded) by utilizing the existing resources. Karnataka is the first state in India to expand the NBEMS (DNB and Diploma) courses in taluk hospitals and to begin DrNB courses in district hospitals. The paper documents the process of implementation of the NBEMS courses at district and taluk hospitals of Karnataka, which has supported in strengthening these hospitals in the state.

The leading role of expert safety knowledge in supporting the mission of caring for patients during man-made and natural disasters: state of emergency medicine in Ethiopia, Myanmar, and Ukraine.

Preparedness to endure extreme situations such as natural disasters or military conflicts is not commonplace in healthcare training programs. Moreover, multidisciplinary teams in health services rarely (if ever) include experts in security. However, when emergency situations occur, prevailing healthcare demands do not cease to exist, and unexpected demands often surge due to the shortage of other services and supplies or as a consequence of the emergency condition itself.With services in 45 countries, AIDS Healthcare Foundation (AHF) has operated in several conflict zones, facing broad and challenging security demands. Since 2017 AHF has implemented the Global Department of Safety and Security (GDSS), a dedicated intelligence and safety program that had a key role in the security monitoring, preparedness, and defense responses, assisting staff members and clients during recent conflicts.In this manuscript, we describe the experience of AHF's GDSS in three recent military conflicts in Ethiopia, Myanmar, and Ukraine, and provide insights into steps that can be taken to assure staff safety and support the mission of caring for patients throughout catastrophic events.

The association between midwifery staffing and reported harmful incidents: a cross-sectional analysis of routinely collected data.

BACKGROUND: Independent inquiries have identified that appropriate staffing in maternity units is key to enabling quality care and minimising harm, but optimal staffing levels can be difficult to achieve when there is a shortage of midwives. The services provided and how they are staffed (total staffing, skill-mix and deployment) have been changing, and the effects of workforce changes on care quality and outcomes have not been assessed. This study aims to explore the association between daily midwifery staffing levels and the rate of reported harmful incidents affecting mothers and babies. METHODS: We conducted a cross-sectional analysis of daily reports of clinical incidents in maternity inpatient areas matched with inpatient staffing levels for three maternity services in England, using data from April 2015 to February 2020. Incidents resulting in harm to mothers or babies was the primary outcome measure. Staffing levels were calculated from daily staffing rosters, quantified in Hours Per Patient Day (HPPD) for midwives and maternity assistants. Understaffing was defined as staffing below the mean for the service. A negative binomial hierarchical model was used to assess the relationship between exposure to low staffing and reported incidents involving harm. RESULTS: The sample covered 106,904 maternal admissions over 46 months. The rate of harmful incidents in each of the three services ranged from 2.1 to 3.0 per 100 admissions across the study period. Understaffing by registered midwives was associated with an 11% increase in harmful incidents (adjusted IRR 1.110, 95% CI 1.002,1.229). Understaffing by maternity assistants was not associated with an increase in harmful incidents (adjusted IRR 0.919, 95% 0.813,1.039). Analysis of specific types of incidents showed no statistically significant associations, but most of the point estimates were in the direction of increased incidents when services were understaffed. CONCLUSION: When there is understaffing by registered midwives, more harmful incidents are reported but understaffing by maternity assistants is not associated with higher risk of harms. Adequate registered midwife staffing levels are crucial for maintaining safety. Changes in the profile of maternity service workforces need to be carefully scrutinised to prevent mothers and babies being put at risk of avoidable harm.

Barriers and facilitators in implementing early essential newborn care of well-born babies in low- and middle-income countries: A mixed-method systematic review.

BACKGROUND: Evidences have demonstrated the effectiveness of early essential newborn care. However, the implementation of early essential newborn care is suboptimal. The aim is to identify and synthesise the barriers and facilitators impacting the implementation of early essential newborn care in low- and middle-income countries. DATA SOURCES: PubMed, EMBASE, Cochrane Central Register of Controlled Trials, PsycINFO, CINAHL, CNKI, Wan Fang Data, SinoMed and Google Scholar. METHODS: Two authors independently screened, performed quality assessment using the Mixed Methods Appraisal Tool and extracted data. This review includes papers that reported the barriers and facilitators of implementing early essential newborn care in low- and middle-income countries from the view of healthcare providers. Barriers and facilitators were coded according to the consolidated framework for implementation research in a deductive way and then been inducted into five common themes. This review followed synthesis without meta-analysis reporting guideline. RESULTS: A total of 28 studies were included. Five inductive common themes influencing implementing early essential newborn care in low- and middle-income countries were system-level healthcare factors, healthcare providers' knowledge and beliefs, the requirements of mothers or families, adapting to routine practice and the working climate of organisation. CONCLUSION: The factors were from system level, facility level and individual level and were inducted into five themes. Based on this review, decision-makers could tailor implementing strategies to narrow the gap between the evidence and implementation. RELEVANCE TO CLINICAL PRACTICE: The study offers guidance for health professionals to identify barriers and facilitators in implementing early essential newborn care and make tailored strategies when implementing early essential newborn care. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contributions.

Evaluation of medical equipment maintenance and skilled manpower requirement among private dental centres in Riyadh, Saudi Arabia: A pilot study.

BACKGROUND: Adequate equipment maintenance is necessary to ensure efficient dental care facilities and satisfactory medical equipment performance. OBJECTIVE: This study aimed to assess maintenance practices and manpower adequacy in private dental centres (DCs) across Riyadh, Saudi Arabia. METHODS: A questionnaire was designed to evaluate equipment maintenance and manpower strength based on international and national standards. Thirty-three private DCs were visited in-person with the designed questionnaire to conduct the study. The Chi-square test and t-test were performed. RESULTS: Only 21 dental centres had a scheduled maintenance plan for medical equipment, whereas the rest had no plan. Furthermore, only 22 DCs maintained equipment maintenance records, while 11 DCs did not have any records. Additionally, the study found a lack of trained personnel to handle medical equipment and overall inadequate maintenance practices. Significant differences were observed between the responses for many questions (p< 0.05). CONCLUSION: These findings increase health risks to both the patient and the user. To address these issues, DC administrators should implement stricter measures to adhere to local DCs standards and hire qualified personnel who can periodically maintain and repair medical equipment.

The effect of the intensive care unit nurse manpower on care behaviours and stress level on the nurses.

BACKGROUND: Nurses working in the intensive care units (ICU) regarding the work-index-nursing work environment, the effect level ICU environment has on the nurses' care behaviors and stress levels of the nurses should be determined. OBJECTIVE: The study aimed to investigate the effect of the nurse manpower on care behaviours and stress level of the nurses working in the ICU. METHODS: This was a cross-sectional and correlational study. The sample of the study consisted of 123 nurses working in the ICUs. The data were collected using the survey form, Distress Thermometer (DT), The Practice Work Environment Scale of the Nursing Work Index (PES-NWI), and Caring Behaviors Scale-24 (CBS-24). RESULTS: The mean age of nurses in the ICU was 30.2±5.6 and the mean of working time in the intensive care unit of nurses in the ICU was 3.7±3.1 years. The mean of the DT was 4.8±3.4, and the mean score of PES-NWI was 2.6±1.0 and the mean score of CBS-24 was 4.7±1.1 in nurses in the ICU. The regression model which was studied to investigate the relationship between caring behaviors and stress and nurse manpower of nurses working in intensive care unit was significant. CONCLUSION: Care behaviors and stress levels of nurses working in intensive care units are negatively affected by insufficient nurse manpower.

Obstetric anaesthesiology: manpower and service provision issues in India.

Obstetric anaesthesiologists play a pivotal role as peripartum physicians steering the team of obstetric healthcare providers towards a continuum of medical education, enhanced training and safer patient care. However, in resource-limited countries, deficiency of human resources and hence services available poses challenges to those attempting to reduce maternal mortality rates. Measures to fill the gap include creating a cadre of uniformly well-trained and certified non-physician anaesthesia providers (NPAPs) supervised by a physician obstetric anaesthesiologist and well-equipped rural and urban health care facilities. The Association of Obstetric Anaesthesiologists of India needs to upscale their outreach programs with regular knowledge updates and practical skill training to the NPAPs, medical graduates and postgraduate doctors in these regions. A combination of strong local administrative will, legislation for the provision of essential supplies and a global collaborative effort using checklists and protocols may help to stem gaps in the provision of safe maternal care.

Manpower cost for a hypertension health campaign: A cross-sectional study.

Introduction: The overall prevalence of hypertension is high, and many people are unaware of their condition. Screening campaigns can effectively identify this group of patients. The study aimed to determine the cost of manpower for a health campaign for detecting undiagnosed hypertension and the prevalence of hypertension. Method: This cross-sectional study was conducted at two health centres. Sociodemographic characteristics, hypertension and treatment statuses were recorded. Blood pressure (BP) was measured by either doctors or nurses using automated BP machines. The cost of manpower was calculated as the average salaries of manpower during the 3-day health campaign divided by the total number of days. The final sum was the cost of detecting undiagnosed hypertension. Results: A total of 2009 participants median age = 50 (IQR = 18-91) were included in the study. The overall prevalence of hypertension was 41.4% (n=832). Among the patients with hypertension, 49.2% (n=409) were unaware of their hypertension status. Conversely, 21.1% (n=423) were known to have hypertension, among whom 97.4% (n=412) were on medications. Among those who were on medications, 49% (n=202) had good BP control. The average total cost of manpower during the 3-day health campaign was RM 5019.80 (USD 1059). The cost of detecting an individual with elevated BP was RM 12.27 (USD 2.59). Conclusion: The prevalence of hypertension and unawareness is high. However, the average cost of manpower to detect an individual with elevated BP is low. Therefore, regular public health campaigns aiming to detect undiagnosed hypertension are recommended.

[The brief characteristic of manpower potential in health care of Greece, Spain, Bulgaria].

The article presents brief descriptive review of manpower resources in health care of Greece, Spain and Bulgaria. It is noted that countries differ in redundancy of specialists at relative deficiency of general practitioners. The medical personnel of analyzed countries are characterized by aging, tendency to migration to other countries, deficiency of paramedical personnel and excess of required number of dentists that is especially pronounced in Bulgaria. Furthermore, accessibility of medical care is reduced by limits of number of patients per one physician established for specified time period in Greece. The salary level of physicians in these countries varies from minimal (Greece, Bulgaria) to maximal in Spain. At that, training of medical personnel is implemented according to Bologna system (bachelor course, magistracy, etc.) and is characterized by long period (4-5 years) of training physician for independent work.

Why Treat Patients with a Major Orthopaedic Surgery Only to Send Them Back to the Vulnerable Conditions That Made Them Sick in the First Place? A Conceptual Scenario to Improve Patient's Journey.

Individuals with severe cartilage degeneration of the hip or knee or collapsed vertebrae that cause spine deformities can suffer from joint and neuropathic pain in the back, disuse of the affected limb, and restriction of movements. Surgical intervention is the most widespread and successful solution to date. There is a general belief that eating healthy and staying physically and mentally active might have a preventive role against musculoskeletal disease occurrence, while instead, we are more certain of the benefits deriving from a healthy diet and exercise therapy after major orthopaedic procedures. These aspects are in fact vital components in enhanced recovery after surgery programmes. However, they are applied in hospital settings, are often centre-dependent, and lack primary and tertiary preventive efficacy since end once the patient is discharged. There is the lack of initiatives at the territorial level that ensure a continuum in the patient's journey towards orthopaedic surgery, home transition, and a healthy and long-lasting life. The expert panel advocates the integration of an intermediate lifestyle clinic that promotes healthy eating, physical activity, and sleep hygiene. In this facility directed by professionals in enhancing recovery after surgery, patients can be referred after the surgical indication and before home discharge. Surgery is in fact a moment when individuals are more curious to do their best to heal and stay healthy, representing a timepoint and opportunity for educating patients on how lifestyle changes may optimise not only their surgical recovery but also long-term future health state.

Shaping the Future: The Transformative Path of the Arab Board of Rheumatology.

Rheumatology fellowship programs represent a pivotal juncture for aspiring specialists, embarking on a transformative journey of expertise and care. The League of Arab States, comprising 22 nations and a collective population of 464.68 million as of 2022, established the Arab Board of Health Specialization in February 1978. This visionary initiative aimed to curb the emigration of Arab physicians and address the scarcity of specialized medical practitioners in the Arab world. Since the establishment of the Internal Medicine specialty in 1979, the curriculum and examinations have undergone sustained refinement and enhancement. In a significant stride, the Arab Board established the Scientific Committee of the Rheumatology Fellowship Program on November 28, 2022. Its main goal is to ensure that graduating fellows will be of high caliber and can contribute to the care of patients with rheumatic disease in the Arab world. This editorial illustrates the historical trajectory of the Arab Board's evolution and chronicles the dynamic expedition of shaping the rheumatology fellowship program.

Workforce survey of Australian health information management graduates, 2017-2021: A 5-year follow-on study.

Background: Employment outcomes of La Trobe University's 2012-2016 health information manager (HIM) graduate cohort were reported previously. Objectives: To identify the 2017-2021 Australia-based, graduate HIMs' early career employment experiences; identify employment roles and destinations; investigate knowledge and skill sets utilised in professional performance; and compare outcomes with the previous study. Method: A cross-sectional design was utilised. An online survey elicited: demographic data, position-related details and knowledge-skills applied in the workplace. Inter- and intra-cohort comparisons were calculated. Results: Of contactable graduates, 75% (n = 150) completed the survey; 90% (n = 132) had held at least one profession-related position postgraduation; 51% gained employment before final examinations and 92% within 6 months. In their first role, 87% joined the public healthcare sector, 47% had worked in two or more positions and 12.3% in three or more positions. Categorisation of position titles showed that 40% had undertaken "health information management" roles, 14.9% "health classification," 16.6% "data management and analytics," 17.4% "health ICT" and 11.1% "other," roles. Almost two-thirds (64.1%) had utilised three or four of the four professional knowledge-skill domains. There was an increase, from the 2012 to 2016 cohort, in those undertaking "data management and analytics" and "health ICT" roles, and a decrease in "health classification" role uptake. Conclusion: Early-career HIMs have very high employability. They engage throughout health care, predominately in the public health sector. Their mobility reflects national workforce trends. The majority utilise all or most of the professional knowledge-skill domains studied at university.

'Thank goodness you're here'. Exploring the impact on patients, family carers and staff of enhanced 7-day specialist palliative care services: A mixed methods study.

BACKGROUND: Healthcare usage patterns change for people with life limiting illness as death approaches, with increasing use of out-of-hours services. How best to provide care out of hours is unclear. AIM: To evaluate the effectiveness and effect of enhancements to 7-day specialist palliative care services, and to explore a range of perspectives on these enhanced services. DESIGN: An exploratory longitudinal mixed-methods convergent design. This incorporated a quasi-experimental uncontrolled pre-post study using routine data, followed by semi-structured interviews with patients, family carers and health care professionals. SETTING/PARTICIPANTS: Data were collected within specialist palliative care services across two UK localities between 2018 and 2020. Routine data from 5601 unique individuals were analysed, with post-intervention interview data from patients (n = 19), family carers (n = 23) and health care professionals (n = 33; n = 33 time 1, n = 20 time 2). RESULTS: The mean age of people receiving care was 73 years, predominantly white (90%) and with cancer (42%). There were trends for those in the intervention (enhanced care) period to stay in hospital 0.16 days fewer, but be hospitalised 2.67 more times. Females stayed almost 3.5 more days in the hospital, but were admitted 2.48 fewer times. People with cancer had shorter hospitalisations (4 days fewer), and had two fewer admission episodes. Themes from the qualitative data included responsiveness (of the service); reassurance; relationships; reciprocity (between patients, family carers and staff) and retention (of service staff). CONCLUSIONS: Enhanced seven-day services provide high quality integrated palliative care, with positive experiences for patients, carers and staff.

Mississippi School of Occupational Therapy and Department.

This paper discusses the development of the Mississippi School of Occupational Therapy, the first occupational therapy education program supported by a state government, and the first to start in the deep south. This article explores what is known about the school and the department to which the school was to supply therapists. The school existed from 1921-1926 under Eleanor Goodwin Morse a student of Eleanor Clarke Slagle, and followed the curriculum design of the Henry B. Favill School of Occupation and continued under Louise Howorth until 1929. The forty-three graduates whose names can be identified, staffed the Department of Occupational Therapy at the Mississippi State Insane Asylum and occupational therapy departments in eleven other states thus spreading the knowledge and skills of occupational therapy throughout the south and east coast.

Approaches and Components of Health Workforce Planning Models: A Systematic Review.

Background: To date, there is still no uniformity in forecasting models for health workforce planning (HWFP). Different countries use various HWFP models, some of which are context-specific. The objective of this systematic review is to determine approaches and components of HWFP models. Methods: A systematic review of studies published in English and Persian between 2004 and 2021 was performed by searching PubMed Central, MEDLINE, Web of Science, Scopus, Eric, and Elmnet databases. Articles that assessed HWFP models, focused on health service delivery, used input-output models, and a clear formulation process were included. Articles that scored ≥20 points on the "strengthening the reporting of observational studies in epidemiology" checklist were considered of acceptable quality for inclusion. Results: Twenty articles were included for qualitative synthesis based on the inclusion and exclusion criteria. Most studies used the mixed method approach "supply and demand", whereas target- and needs-based approaches were used less frequently. The number of components used to estimate supply, demand, needs, and targets were 42, 32, 11, and 6, respectively. In addition, several unique factors used in the various HWFP models were identified. Conclusion: Different approaches are used in HWFP models, which is indicative of the lack of consensus on this topic. High diversity in the identified factors is related to the approach used and the context in which the model is applied.

Need Analysis of Indian Critical Health Care Delivery in Government Sectors and Its Impact on the General Public: A Time to Revamp Public Health Care Infrastructure.

Background: Poverty is directly linked to public health care delivery in many ways and dimensions. Every aspect of the human sphere is preplanned, but a health crisis is the only emergency which pushes humanity into severe economic stress. Therefore, every nation aims to safeguard its citizens from a health crisis. In this aspect, India needs to improve its public health infrastructure in order to protect its citizens and save them from poverty. Objectives: (1) To assess the current pitfalls in public critical health care delivery, (2) to analyze whether the health care delivery matches the requirements of its population in every state, (3) to produce solutions and guidelines to overcome the stress in this priority area. Materials and methods: Data regarding the critical care workforce, which includes critical care doctors and nurses, were taken from official websites and other sources. Critical care infrastructure data were retrieved from the Internet sources. Data were validated by consulting state government sources and cross-checked for bias elimination. The data were analyzed using the "Statistical Package for Social Sciences" software version 20, and were presented using descriptive statistics. Results: There is a 1:10 percentage of deficit in the case of critical care workforce and infrastructure when compared with its need analysis. Critical care medicine specialists are in 1:75 when compared to other specialties. Conclusion: Overall, the public sector critical care needs a total boost through out of box solutions. According to the Stockholm International Peace Research Institute (SIPRI), India spent the third most on defense in the world in 2021. India spent 76.6 billion dollars on its military in 2021, up 33% from 2012 and 0.9% from 2020. However, since India is considered a fast-growing economy, there is still a huge disparity in critical care. Without resetting critical health care, India cannot grow in welfare indices even if it is among the top gross domestic product (GDP) countries.

Disparities in the level of COVID-19 health literacy and the associated factors among employees in long-term care facilities in Taiwan.

BACKGROUND: Coronavirus disease 2019 (COVID-19) poses a significant threat to the safety of residents in long-term care facilities, and the staff of long-term care facilities are essential in the care and prevention of major infectious diseases and therefore require good health literacy to ensure the health of residents. The main objective of this study was to examine the health literacy of staff in long-term care facilities and analyze the factors associated with their COVID-19 health literacy in Taiwan to provide a basis for the response mechanism to emerging infectious diseases. METHODS: A cross-sectional survey with a structured questionnaire by a convenience sample method and to assess the COVID-19 health literacy of caregivers working in long-term care facilities in this study. The COVID-19 health literacy scale was a self-administered scale designed to combine the concept of "health literacy" with the 3 levels and 5 stages of preventive medicine. A total of 385 workers from 10 long-term care facilities were surveyed as the study sample, and the validated questionnaires were statistically analyzed using SPSS version 22.0 statistical software. A multivariate logistic regression model was used to establish the associated factors of the COVID-19 health literacy level. RESULTS: Overall, the mean COVID-19 health literacy score was 88.7 ± 10.4 (range: 58-105). Using a quartile scale, 92 (23.9%) of the study participants had low health literacy (health literacy score < 82), 190 (49.3%) had average health literacy (health literacy score 82-98), and the remaining 103 (26.8%) had good health literacy (health literacy score 99-105). Statistical analysis revealed significant differences (p < 0.05) in the COVID-19 health literacy score by demographic variables (education, job category, number of daily service users, and training related to infectious disease prevention and control) of the study population. The logistic regression analysis of the COVID-19 health literacy level (> 82 vs. ≤82) showed a significant difference in the study sample by gender (male vs. female, OR = 2.46, 95% CI = 1.15-5.26), job category (nurse practitioner vs. caregiver, OR = 7.25, 95% CI = 2.46-21.44), monthly service hours (> 160 h vs. 40-79 h, OR = 0.044, 95% CI = 0.07-0.97), experience caring for confirmed COVID-19 patients (yes vs. no, OR = 0.13, 95% CI = 0.02-0.98), and training related to infectious disease prevention and control (yes vs. no, OR = 2.8, 95% CI = 1.52-5.15). CONCLUSIONS: This study recommends that facilities provide immediate updated COVID-19 information to staff, especially frontline caregivers, and specifically enhance COVID-19 infection control education training for all facility staff to eliminate health literacy disparities.

Organizational Labor Flow Networks and Career Forecasting.

The movement of employees within an organization is a research area of great relevance in a variety of fields such as economics, management science, and operations research, among others. In econophysics, however, only a few initial incursions have been made into this problem. In this paper, based on an approach inspired by the concept of labor flow networks which capture the movement of workers among firms of entire national economies, we construct empirically calibrated high-resolution networks of internal labor markets with nodes and links defined on the basis of different descriptions of job positions, such as operating units or occupational codes. The model is constructed and tested for a dataset from a large U.S. government organization. Using two versions of Markov processes, one without and another with limited memory, we show that our network descriptions of internal labor markets have strong predictive power. Among the most relevant findings, we observe that the organizational labor flow networks created by our method based on operational units possess a power law feature consistent with the distribution of firm sizes in an economy. This signals the surprising and important result that this regularity is pervasive across the landscape of economic entities. We expect our work to provide a novel approach to study careers and help connect the different disciplines that currently study them.
