Do Acquisitions Enrich Corporate Knowledge and Organizational Capital?

We examine the impact of frequent acquisitions on the firm's knowledge capital and organizational capital. We find that frequent acquirers are more likely to have greater knowledge and organizational capital. Firms with higher knowledge capital are also likely to pursue more acquisitions, contrary to the current notion that firms deficient in R&D are more likely to pursue acquisitions. Our results suggest firms enhance exploration and exploitation capabilities through active acquisition programs. The greater a firm's absorptive capacity, the stronger the positive effects of the acquisition frequency on the knowledge capital and organizational capital. Our results suggest that frequent acquisitions decrease a firm's inertia, broaden its knowledge base, and enhance its core capabilities. We find that in-house R&D and externally acquired R&D via acquisitions are complements, not substitutes, contrary to the existing findings. Our results further suggest that firms with higher absorptive capacity (knowledge capital) are more likely to engage in frequent acquisitions.

Three-dimensional modeling of ancient yiyuan architecture using static laser scanning technology

Abstract The awareness of protecting traditional culture and humanistic landscapes is increasing year by year, and the protection of ancient gardens is becoming more and more a consensus among people. This paper takes the architectural profile of Guyi Garden as the research basis, introduces the specific application of 3D laser scanning technology, plans the scope of architectural data acquisition in Guyi Garden, and designs the corresponding architectural data acquisition program. With respect to the acquired point cloud data of GuYiYuan, the bilateral filtering algorithm is used to reduce the noise of the data, the curvature thinning algorithm is combined to reduce the point cloud data of the buildings in GuYiYuan, the point cloud data are spliced based on the connection point, and the ICP algorithm with the introduction of the optimization of the rotational angle constraints is introduced to realize the alignment of the point cloud data. In addition, the shadows generated from the point cloud data are removed by combining the relighting method, and the linear transformation method is also used to globally correct the texture image generated from the point cloud data. The point cloud density was reduced from 0.95m² to 0.01m² when the thinning rate was increased from 8% to 96%, and the alignment error of the improved ICP algorithm under 25dB Gaussian white noise was only 0.083*10-4mm. The maximum error accuracy of the two-dimensional model of Yiyi Nodang generated based on the point cloud data was only 0.007m, and the error of the three-dimensional model was controlled to be within the range of ±9mm. Accurate architectural data can be obtained through the use of 3D laser scanning technology, leading to a new method for digitally preserving historical buildings.

Ommunity Policing as a Strategy for Crime Reduction in Nigeria. (A Case Study of Yola North Local Government Area of Adamawa State)

Community policing is a symbiotic and concerted effort of the police and members of the host communities to reduce the incidence of crime and criminal activities. Nigeria, as a country, has embraced the concept of community-based policing to forestall crime and criminal activities since the return of democracy in 1999. This research critically scrutinizes the ideology and beliefs of community policing in the Nigerian context, aiming to offer solutions to the major setbacks of community policing inNigeria. A non-probability sampling technique was employed for the current study. Self-constructed questionnaires were used to acquire data. Results revealed that the community members are in constant healthy relationship with the police, but the police collaboration with the community members regarding crime control/detection is not encouraging. The effort of the police authority in crime detection and control is commendable, and the fear of crime has been declining since the initiation of community policing. Success was attributed to the constant collaboration of the police with other security agencies. The residents fully supported the concept of community policing. Still, they suggested that massive employment, funding security agencies, and organizing skill acquisition programs to engage the unemployed will greatly help in crime reduction in addition to the concept of community policing. The challenges faced by the security agencies include recruitment of unqualified personnel, insufficient crime-fighting equipment/patrol vehicles, inadequate remuneration of the security personnel, and lack of trust in the security agencies by the residents.

Effects of the Reduction of the Food Purchase Program Resources for the Family Farmer

The Food Acquisition Program (FAP) created in 2003 during the first term of President Luiz Inácio Lula da Silva represents a change in the way family farmers are benefited. However, in the period of 2019-2022 (Bolsonaro’s Government) the setback in the implementation of social policies, which began during President Dilma Roussef’s second term, worsened. In this context, this article sought to investigate the effects of the partial implementation of the FAP on the lives of family farmers in the municipality of Maracanaú-CE in that period. This is an excerpt from the dissertation “Evaluation of the Municipal Food and Nutrition Security Policy in the Municipality of Maracanaú-Ceará”, which was developed through a Fourth Generation Assessment from February to November 2022, using the Hermeneutic Circle Dialectic. The informants were family farmers benefiting from the program. Empirical data were constructed through individual semi-structured interviews, field observation and field diary, which allowed creating the empirical categories: Benefit of participating in the FAP; Challenges for maintaining family farming in recent years and Support from municipal managers to family farmers. The study concluded that the partial execution of the FAP due to the reduction in the transfer of federal resources had effects regarding the guarantee of sales, the reduction of sales and the value of products, on the conditions for purchasing equipment and supplies. This situation was worsened by insufficient support from municipal management in terms of providing resources and technical assistance, which generated instability in the segment and discouraged people from continuing with family farming. These findings allow us to reflect on the importance of the FAP to keep family farmers in the field, generate security and stability, and promote quality of life not only for the segment, but for consumers who seek healthy food produced in a sustainable way.

Empowering Rural Community of Laguna for Maximum Societal Impact through Skills Acquisition

Furthermore, social purpose needed to be demonstrated the socioeconomic benefits of their training programs to secure future funding, public or private, but proving their successful delivery even if it may be difficult to determine.

A comparative experiment between textual requirements and model‐based requirements on proxies for contractual safety

AbstractRequirements form the backbone of contracting in acquisition programs. Requirements define the problem boundaries within which contractors try to find acceptable solutions (design systems). At the same time, requirements are the criteria by which a customer measures the extent that their contract has been fulfilled by the supplier. In this context, the quality of a requirement set is determined by the level of contractual safety that it yields. Unfortunately, textual requirements do not provide acceptable levels of contractual safety, as they remain a major source of problems in acquisition programs. Model‐based requirements have been proposed as an alternative to textual requirements, although this promise has not been demonstrated yet. This paper addresses the main question of whether using model‐based requirements improves the contractual safety of acquisition programs compared to using textual requirements. The level of adequate applicability, bounding, necessity, and completeness achieved by model‐based requirements are empirically measured using an experimental study with aerospace engineering and industrial and systems engineering students on a space system application. The results show that model‐based requirements outperform textual requirements in these four variables.

Comparing distributed versus massed practice on functional recovery and Brain-Derived Neurotrophic Factor (BDNF) in acute stroke subjects.

Globally, stroke is known to be one of the major health problems, resulting in disability among an aging population. Rehabilitation is a process of re-learning of skills, lost due to brain injury. Many factors influence motor learning post neurological insult and practice is one of the key factors which influence relearning or reacquisition of lost motor skills. Practice can be varied concerning order (blocked or random), scheduling (massed or distributed), or whole and part practice. The study observed the effect of variations in practice schedules on motor and functional recovery. Thirty-two acute stroke subjects were recruited and equally divided into two groups (16 in massed and 16 in distributed). Both groups received an accelerated skill acquisition program (ASAP) for six sessions a week for 2 weeks. Pre- and post-outcome measures included stroke rehabilitation assessment of movement (STREAM) for motor recovery, modified Barthel index (MBI) for functional recovery, and brain-derived neurotrophic factor (BDNF) for neuroplasticity. The median scores of participants in the massed practice group before the intervention, of STREAM total, MBI, and BDNF were 23.5, 19, and 0.65, respectively, whereas post values of STREAM total, MBI, and BDNF were 40.5, 60.5, and 0.75, respectively. The median scores of the distributed practice group of the pre-STREAM total, MBI, and BDNF were 23.5, 6.5, and 0.70, respectively, whereas the post-STREAM total, MBI, and BDNF were 41, 45.5, and 0.80, respectively. P-value was reported to be <0.05 while comparing pre- and post-values of STREAM, MBI, and BDNF within both intervention groups. The median change scores of STREAM, MBI, and BDNF reported P ≥ 0.05 when compared between the groups. Both the groups had significant recovery post-intervention designed based on ASAP, about impairment mitigation, pursuing skilled movement leading to significant functional gains. Appropriate timing along with optimal dosage became an active ingredient in functional recovery in acute stroke subjects. The distributed practice might have added effect of spacing, resulting in easier learning and accuracy of skills. The study reveals that distributed practice can be part of regular clinical practice to enhance functional recovery in acute stroke rehabilitation.

The Indian Navy Navis in Mari Amissa: At a Crossroads in the Twenty-first Century

This article hypothesises that the Indian Navy’s modernisation is directionless, the Latin phrase ‘Quod perierat navis’ meaning ‘a lost ship’ metaphorically representing the Indian Navy. While China’s naval expansion is set to revive great power naval brinkmanship in the twenty-first century, India’s naval modernisation appears rudderless without a critical appraisal of new challenges and countermeasures. This article hypothesises that this stems from the lack of an objective maritime doctrine resulting in a confused capability acquisition programme. The article puts forward three questions: First, is there a military strategy or white paper on India’s maritime threats and strengths? Second, is the Indian Navy bolstering its marine defences? Third, how might limited resources optimise capacities to meet challenges? To evaluate Indian Navy modernisation, this article will employ a qualitative method to explore the strategic objectives and utilisation of emerging naval technologies by the Indian Navy and its prospective rivals, and conclude by proposing suitable course corrections.

Gender separation of entrepreneurship skills acquisition programmes for economic development

Learning entrepreneurial skills has taken on a significance never before seen as a result of their significance to economic growth. In this study, the impact of skill development initiatives on Nigeria's economic development was examined. The study used two objectives: to look into how gender differences in skill acquisition affected economic development and to determine how skill acquisition affected economic development. A quantitative method in the form of a questionnaire was used to sample two hundred (200) unemployed youths. Results revealed that there is a significant gender difference in skill acquisition for economic development and that skill acquisition has a significant influence on economic development. The study concluded that youths perceive skill acquisition programmes to have a positive effect on employment creation. Likewise, gender equality is to be considered in skills acquisition training. In general, the involvement of both genders in skill acquisition programmes will go a long way toward improving the nation's economic development.

Self-powered retractable reel sensor for crack monitoring and warning in civil infrastructures

Crack occurrence and propagation are among the critical factors that affect the performance and lifespan of civil infrastructure such as bridges, buildings, etc. Therefore, numerous crack detection and characterization techniques have been developed over the past decades. In this study, we proposed the self-powered with the merits of cost-affordable, high resolution, and wide monitoring range to monitor small cracks in infrastructure. The self-powered retractable reel sensor includes two triboelectric nanogenerator (TENG) sensing units for low and high speed fracture monitoring, respectively. By using the principle of retractable reel structure, the linear motion of the crack is converted into the rotation of the TENG. Through peak extraction and pulse counting, the testing of crack velocity and displacement was realized simultaneously. A real resolution of 0.222 mm are achieved through the structural design and electrical performance characterization. With the help of the LabVIEW platform and multi-channel data acquisition program, its application in crack monitoring and early warning is successfully demonstrated. This work presents a novel self-powered sensor for crack monitoring and early warning, such a strategy is potentially available for distributed sensor construction towards structural health monitoring (SHM) of the infrastructure.

Purpose: The study appraised youth empowerment programmes through entrepreneurial skills acquisition for self-reliance in Ondo State, Nigeria. Theoretical framework: The conceptual framework was developed based on an extensive literature review to establish the relationship between youth empowerment, entrepreneurial skills acquisition and self-reliance. This framework serves as a guiding structure for the study, determining the way out of the virulent, devastating, torturing, and continuous menace of poverty and unemployment bedeviling the youths of Nigeria and proffer lasting solution through entrepreneurial skills acquisition for self-reliance. Design/Methodology/Approach: The study adopted empirical research approach. Data was gathered from four hundred and fifty participants drawn from six Entrepreneurial Skills Acquisition Centres in three Local Government Areas of Ondo State. The collection of data was by the means of a questionnaire that was structured and well-validated titled Entrepreneurial Skills Acquisition for Job Creation Questionnaire. Descriptive and inductive statistics were used for the data analysis. Findings: The outcome revealed that many jobless school leavers and graduates in Ondo State were completely ignorant of training opportunities provided by Ondo State Government due to inadequate publicity of the programmes. The Entrepreneurial Skills Acquisition Programmes were not sufficiently funded; most of the Centre buildings were dilapidated and poorly maintained; while the resource persons at the Centres were grossly inadequate and poorly motivated. The acquired entrepreneurial skills have been helping the recipients to set up small-scale business enterprises for self-employment and reliance. Research, Practical and Social implications: The study contributes immensely and shows that it is no more contestable that in Nigeria today, the acquirement of appropriate entrepreneurial skills will greatly assist the jobless school leavers and tertiary educational institutions graduates in ameliorating the problem of unemployment and poverty and also lessen the several crimes and social vices commonly committed by most youths of Nigeria. The Nigerian youths who have acquired entrepreneurial skills will undoubtedly decide properly on the business enterprise to embark upon and how to seek initial financial assistance to put it in progress. Originality/Value: The conceptual framework of the study, its empirical research approach, incomparable modality, and practical recommendations contribute to the existing body of knowledge on youth empowerment programmes through entrepreneurial skills acquisition which champions the reduction of unemployment and poverty in Nigeria. It as well providing valuable direction for stakeholders in building a supportive creativity in the educational system.

It also identified the various factors responsible for poverty and youth unemployment in Nigeria. It highlighted the rationale for Nigerian youths to acquire vocational and entrepreneurial skills for self-reliance, income generation, wealth creation and employment generation for others. Theoretical Framework: The aim of vocational and entrepreneurial skills acquisition is to make it practicable in order to drive and deliver the purpose of job creation and poverty alleviation among Nigerian youths. Making it more practicable achieves the driving force to creating economic values and creative business engagements by Nigerians. The focus also provides job opportunities for the teeming Nigerian youths, channels their future to productive activities and turn to make poverty and unemployment to be things of the past if the practicability is achieved through entrepreneurial activities. Design/Methodology/Approach: The study adopted the mode of conducting literature review and conceptualization of the variables and x-rayed the reasons for poverty and unemployment and deepen how the social problems can be identified and reduced to the barest minimum in Nigeria. Findings: Our findings revealed there is serious poverty and unemployment in Nigeria. It as well suggest that it is of valuable and useful direction to promote practicable skills acquisition among Nigerian youths and that the curricula of Nigerian educational institutions should be more pragmatic and have built-in-job training programmes that would enable students to acquire relevant practicable vocational and entrepreneurial skills required for self-employment, job and wealth creation and poverty alleviation. While all stakeholders should be actively involved in the funding of vocational and entrepreneurship education. Research, Practical &amp; Social implications: This study in its focus contributes to a better understanding of the important role being played by entrepreneurial skills acquisition in achieving practicable vocational skills and to develop entrepreneurial attitudes of Nigerian youths that will form the economic growth of the country through their engagements and make them employers of labour through their acquired practicable vocational skills acquisition to better the society. This study also contributes to a better understanding of the causes of the menace which therefore proffers solution to tackling the problem of poverty among Nigerian youths through the provision of a viable, robust, comprehensive and practical-oriented vocational and entrepreneurship education. It also expressed how the collective responsibility of all prominent Nigerians could be keyed-into supporting entrepreneurship programmes in Nigeria in the area of funding of vocational and entrepreneurship education in Nigeria which both Government at Federal, State and Local Government levels and the Non-Govermental Organisations (NGOs). Originality/value: The added value of this study provides insights on how vocational entrepreneurial skills acquisition programmes can be practicable effective in a way to structure the future of Nigerian youths and citizens for productive economic activities. It is as well sought how poverty and unemployment can be reduced and make citizens focus for economic growth and self-dependence businesses.

Batched-image detection model and deployment method for tunnel lining defects using line-scan cameras based on experiments study

High-performance line-scan cameras are highly accurate and efficient for tunnel detection, however, the exponential growth of image data creates new challenges for real-time image processing. The inference speed of existing tunnel detection algorithms is insufficient for massive amounts of image data, and traditional data structures limit the parallelism of the detection system, thereby reducing the speed of image processing. In this study, a deep learning (DL) network is developed for real-time tunnel defect detection based on the you only look once (YOLO) family. The network includes innovative defect feature-extraction modules, optimization of the network architecture, and improvement of the decoupling heads to increase defect detection accuracy and efficiency. Furthermore, we developed critical technologies for real-time detection. First, our method employs a deployment method for DL networks based on TensorRT, which enables our network to be applied directly to C++ image acquisition programs away from the traditional DL frameworks. The proposed line-scan data structure enables the raw images to be fed into the neural network in batches, which, combined with the simultaneous technique of image acquisition, detection, and storage, significantly increases the efficiency of real-time detection. The paper demonstrates the advantages of the proposed model and hardware system through an experiment study. The test results indicate that the mean average precision and F1-score of our network were 86.07% and 84.53%, respectively, while it had 21.42 M parameters. Combined with the proposed storage strategy, a recall rate of more than 90% was achieved for defect detection. Moreover, batch image processing method has a significant advantage in terms of inference speed, with 243.9 FPS in PyTorch, 381.46 FPS in TensorRT, and 305.3 FPS in real-time detection, which is five times faster than existing defect-detection models. This study significantly increases the efficiency of tunnel lining detection, which has positive implications for the visual detection of other infrastructures.

Pooled Longitudinal Dataset on the Assessment of an Apprenticeship-Based Entrepreneurship Intervention in Nigeria

Abstract This dataset presents longitudinal data collected through four surveys (in six-monthly intervals) of fresh university and polytechnic graduates in Nigeria. The data were collected from 21,940 unique young men and women who underwent National Youth Service Corps (nysc) programme across ten states in Nigeria. The nysc programme is a compulsory one-year national service that all Nigerians under the age of 30 years must undergo after graduation. A key component of the one-year service is the Skills Acquisition and Entrepreneurship Development (saed) programme of the nysc. The dataset is useful for many purposes. It contains enough information to fully profile the entrepreneurship and apprenticeship characteristics of the fresh graduates. Moreover, it can be used to quantify the potential pool of future entrepreneurs among highly educated Nigerian youth. The dataset was originally used to assess the impact of saed, being an apprenticeship-based entrepreneurship intervention, on entrepreneurial outcomes among young persons. However, its use may also extend to an assessment of the impact of compulsory entrepreneurship training in the Nigerian university system that produced most of the respondents.

Quantifying population-level conservation impacts for a perpetual conservation program on private land

Area-based targets, such as percentages of regions protected, are popular metrics of success in the protection of nature. While easily quantified, these targets can be uninformative about the effectiveness of conservation interventions and should be complemented by program impact evaluations. However, most impact evaluations have examined the effect of protected areas on deforestation. Studies that have extended these evaluations to more dynamic systems or different outcomes are less common, largely due to data availability. In these cases, simulations might prove to be a valuable tool for gaining an understanding of the potential range of program effect sizes. Here, we employ simulations of wetland drainage to estimate the impact of the United States Fish and Wildlife Service Small Wetlands Acquisition Program (SWAP) across a ten-year period in terms of wetland area, and breeding waterfowl and brood abundance in the Prairie Pothole Region of North Dakota, South Dakota, and Montana. Using our simulation results, we estimate a plausible range of program impact for the SWAP as an avoided loss of between 0.00% and 0.02% of the carrying capacity for broods and breeding waterfowl from 2008–2017. Despite the low programmatic impact that these results suggest, the perpetual nature of SWAP governance provides promising potential for a higher cumulative conservation impact in the long term if future wetland drainage occurs.

Who are the Poor Farm households' in Nigeria and is this Population Changing Over Time?

ABSTRACT: Reducing poverty in developing economies is a major challenge faced by the development stakeholders. Although poverty is a worldwide phenomenon, it has been observed that Nigeria is one of the countries that is worst hit by the poverty with biting effects more on the rural dwellers where the bulk of the population lives. Using the nationally representative household survey panel data by the World Bank/National Bureau of Statistics, from the 2012 to 2016 period to provide answers to what are the household demographic, farm, and geospatial characteristics that drive the likelihood of farm households entering, exiting, and re-entering poverty using the costs of basic needs approach as a marker of poverty. Four poverty levels were used in analyzing the household survey data. The two waves of poverty mobility in Nigeria approximately revealed 51.2 percent of poor farm households' in wave 1, and 42 percent in wave 2 were at risk of spending their entire lives in poverty. The probability of existing and entering two-year poverty mobility which started at 25 percent rose to 45 percent for four-year poverty mobility indicating that over time more farm households, have experienced changes in the status of their consumption expenditure relative to the poverty line. Close to households who begin poor, those who moved out of poverty in any of the other years had better endowments in terms of land and livestock ownership, urban residence, and involvement in non-farm income portfolios. It is concluded that older heads, higher educational attainment, engagement in crop/livestock production, and non-farm livelihood activities, strongly reduce the likelihood of farm households' poverty entry. Therefore, policy strategies aimed at dealing with poverty mobility should be heterogeneous across the poor farm households. Also, as the chronically poor lack physical assets and earning endowments, policy efforts should focus on education or other forms of skills acquisition programs in order to raise their livelihood portfolios and boost their earning capacity.

A Scalable Method to Improve Large-Scale Lidar Topographic Differencing Results

Differencing digital terrain models (DTMs) generated from multitemporal airborne light detection and ranging (lidar) data provide accurate and detailed information about three-dimensional (3D) changes on the Earth. However, noticeable spurious errors along flight paths are often included in the differencing results, hindering the accurate analysis of the topographic changes. This paper proposes a new scalable method to alleviate the problematic systematic errors with a high degree of automation in consideration of the practical limitations raised when processing the rapidly increasing amount of large-scale lidar datasets. The proposed method focused on estimating the displacements caused by vertical positioning errors, which are the most critical error source, and adjusting the DTMs already produced as basic lidar products without access to the point cloud and raw data from the laser scanner. The feasibility and effectiveness of the proposed method were evaluated with experiments with county-level multitemporal airborne lidar datasets in Indiana, USA. The experimental results demonstrated that the proposed method could estimate the vertical displacement reasonably along the flight paths and improve the county-level lidar differencing results by reducing the problematic errors and increasing consistency across the flight paths. The improved differencing results presented in this paper are expected to provide more consistent information about topographic changes in Indiana. In addition, the proposed method can be a feasible solution to upcoming problems induced by rapidly increasing large-scale multitemporal lidar given recent active government-driven lidar data acquisition programs, such as the U.S. Geological Survey (USGS) 3D Elevation Program (3DEP).
