Community structure and regeneration capacity of mangrove forest
Authors: Demapitan Marylene M. , Salvaña Florence Roy P. , Cano-Mangaoang Cherie
Published: January 2024

Mangrove forests play a vital role in the environment. They provide a number of ecosystem services for supporting marine biodiversity, humans, and other living organisms inhabiting the area. This study aimed to determine the community structure and regeneration capacity of mangrove forests in Lebak, Sultan Kudarat, Philippines. Community structure was determined through relative density, relative frequency, relative dominance, and importance value. Using the center point circular plot method, 13 plots with 40 m diameter were established in two sampling sites: natural stand and reforested. Shannon-Weiner diversity and evenness indexes were used to determine species diversity and distribution, respectively. This study recorded a total of 14 462 individuals within the 1256 m² sampling plots, having Rhizophoraceae as the most abundant family with seven species that cover about 71% of both mangrove ecosystems. The vegetation analysis revealed that Ceriops tagal (70.35%) and Rhizophora mucronata (96.51%) had the highest importance value in the natural stand and reforested mangrove forests, respectively. Furthermore, these two species were also accounted for having the highest regeneration contribution among all species in each site. Shannon-Weiner diversity index revealed that the natural stand was more diverse compared to the reforested mangrove forest. However, the Shannon-Weiner evenness index showed that species in the reforested mangrove forest are more evenly distributed than species in the natural stand. Natural mangrove stands in Lebak have complex community structure and have higher regeneration capacity than the reforested mangrove forest. With this, the study suggested continuing the best practices employed for mangrove conservation in the area and crafting a strategic plan for sustainable mangrove resource utilization.
Unpacking Taiwan’s ‘People-Centred’ New Southbound Policy in Indonesia: A Transnational Perspective
Authors: W. KABINAWA Luh Nyoman Ratih
Published: January 2024

Almost eight years since the start of Taiwan’s people-centred New Southbound Policy (NSP) in 2016, various discussions have arisen regarding the policy’s efficacy in enhancing Taiwan’s external relations with targeted countries in the Indo-Pacific region. Most scholars have primarily addressed this policy from a state-centric perspective, focusing on the impact of the policy on bilateral interstate relations. Contrary to the existing approach, this article employs a transnational perspective by looking at the practice and success of the policy from both state and non-state level analysis. The use of this approach gives a comprehensive understanding of the nature of the NSP and offers an alternative view on the study of foreign policy by focusing on the transnational level of interactions. Drawing on the case study of the talent exchange program between Indonesia and Taiwan, this article argues that while the NSP has improved the number of student, worker and academic exchanges between Taiwan and Indonesia, the policy has not achieved its aim of extending ‘genuine two-way’ exchanges, resulting in asymmetrical relations that present challenges to the overall achievement of the NSP. Keywords: New Southbound Policy, transnational politics, foreign policy, Taiwan, Indonesia. *
Views and Perceptions of Indonesia among the Second-Generation of Taiwanese-Indonesians after the New Southbound Policy (NSP)
Authors: N​​​​G Yufita
Published: January 2024

Taiwan is a multicultural country. In addition to its diverse local communities, Taiwan is home to many migrants, including intermarriage migrants between Taiwanese men and Southeast Asian women. The intermarriage and second generation, which are children born from intermarriage families, created some social integration issues in Taiwanese society. This is because many Taiwanese have a prejudice against people from Southeast Asia, as most of them initially worked in Taiwan as migrant workers. The implementation of Taiwan’s New Southbound Policy (NSP) offers some opportunities for migrants to be noticeable. The second generation from this intermarriage also has the opportunity and privilege under the NSP policy. This research is based on a study of the views of the second generation of Taiwanese-Indonesian intermarriage families, particularly on their mothers’ culture after the implementation of NSP. This paper argues that the second generation, particularly from Taiwanese- Indonesian intermarriage families, experience a struggle to comprehend their identities within Taiwanese society and their perceptions of the implementation of NSP. The interview method was conducted to delve into the feelings of the Taiwanese-Indonesian second-generation children. Keywords: migrants, intermarriage, second generation, Taiwan, NSP. * Yufita
Making Middle-Power Alignment Work: Reinforcing Taiwan-Vietnam Collaboration in the Semiconductor Industry
Authors: Tam Sang HUYNH , Thi Thuy An VO
Published: January 2024

Through their joint initiatives, emerging middle powers are taking on a bigger role in the Indo-Pacific. But current scholarship on middle powers mainly focuses on countries with well-established reputations, such as Australia, Canada, South Korea, and Japan. Taiwan and Vietnam are two prime examples of emerging middle powers whose role and contributions have been under-examined. The authors contend that, against the backdrop of US-China technology competition, Taiwan and Vietnam should enhance collaboration in the semiconductor industry in an effort to forge closer ties and navigate geopolitical shoals and reefs, leading to the development of a more resilient semiconductor value chain. This paper discusses Taiwan’s crucial role as a potent player in the global semiconductor business in addition to presenting Vietnam’s aspirations to become Southeast Asia’s hub
Current Procedural Practices of Family Medicine Teaching Physicians
Authors: Newman Allison R. , Heidelbaugh Joel J. , Klemenhagen Kristen , Michelfelder Aaron J. , Power David V. , Hougas James E.
Published: January 2024

Background and Objectives: Proficiency in procedural care achieved during residency is a major driver of family physician scope of practice. To date, no inventory exists of the advanced procedures and clinical skills performed by teaching family physicians. This study comprises the first such survey and assesses the attitude of respondents toward the importance of family physicians performing procedures.
Methods: We sent a clinical skills inventory to a convenience sample of teaching family physicians employed at 18 medical school-affiliated, community, and military residency programs across the United States.
Results: The overall response rate was 46% (N=337). Respondents performed a median of 12 advanced procedures and clinical skills (IQR: 8-18). Endorsed procedures ranged from skin biopsy (n=316, 93.8%) and joint injection (n=279, 82.8%) to colonoscopy (n=21, 6.2%) and cesarean delivery (n=23, 6.8%), and reported skills ranged from medication-assisted treatment (n=181, 53.7%) to highly active antiretrovial therapy (n=35, 10.4%). Gender and career stage were associated with statistically significant differences in endorsement of specific procedures. For example, fracture management was more likely to be performed by late- versus early-career faculty (54.1% vs 24.2%, P<.001) and by male versus female respondents (54.9% vs 24.2%, P<.001). Most respondents (84.3%) agreed that future family physicians should learn procedures and advanced clinical skills.
Conclusions: Family medicine teaching faculty perform a wide array of procedures and advanced skills. Apparent differences by career stage and gender identity in the performance of some of the procedural and skill areas may portend a shift in the procedural training of future family physicians.

Authors: Mazander Megan , Rumenapp Joseph , Lee Derek , Ong Charmine , Floramo Emily , Benjamins Maureen , Chen Melissa
Published: January 2024

Background and Objectives: Student-run free clinics (SRFCs) are settings in which students in health professions gain clinical experience, often while providing free or reduced-cost health care to the surrounding community. The current literature quantifies the many benefits these clinics provide to their patients and the impact they have on students’ future careers; but few previous studies have assessed the financial impact of the education provided at an SRFC. We report on a net educational benefit, an educational benefit to educational cost ratio, and a net educational benefit to educational cost ratio of one SRFC from the perspective of the university.
Methods: We calculated the value of education by multiplying all student hours worked in the clinic by the associated value of 1 hour in the typical tuition-based curriculum. Clinic educational costs and student hours were obtained from clinic records from August 1, 2021 through July 31, 2022.
Results: We found the total educational value students received to be $73,571 over one academic year. The educational operating expenses of the clinic totaled $9,053, resulting in a benefit-cost ratio of 8.13.
Conclusions: This analysis demonstrated a potential financial advantage of operating an SRFC when assessing clinic education expenses in relation to the value of university-generated education. Our research may serve as a starting point to showcase the economic benefit of SRFCs to their parent institutions and encourage further analysis of other benefits SRFCs may provide to institutions of higher education.
Population Projection of Mozambique
Authors: Jamo Gabriel
Published: January 2024

In this paper, the evolution of a dynamical system representing the population growth of Mozambique is analyzed. The correspondence between the boundary value problem and the integral equation is leveraged to address the issue of the local existence of solutions to the boundary value problem. The conclusion that the function converges to a function that is the unique solution to the boundary value problem is arrived at by way of constructing a sequence of approximations using Picard’s method of successive approximations and contraction mapping. The exponential function is globally Lipschitz, hence uniformly continuous; however, its solution does not converge to a fixed point implying that the population will grow without bounds as t→∞. The logistic model solves T (ϕ) = ϕ, whence T has a unique fixed point ϕ that is a continuous solution to the integral equation and consequently to the boundary value problem. Therefore, population growth is bounded. In addition, this function is locally Lipschitz and, therefore, not uniformly continuous.
The inter-relationship among corporate governance, artificial intelligence, and innovation
Authors: Gouiaa Raef , Huang Run
Published: January 2024

Although research in the field of corporate governance has been exhaustive recently many scholars have focused on the relationship between corporate governance attributes and artificial intelligence, corporate governance attributes and corporate innovation, there are few studies that combine corporate governance, artificial intelligence and corporate innovation. The main reason is due to the quantitative difficulties in measuring and distinguishing artificial intelligence activities and corporate innovation activities in enterprises. This study examines the relationships among corporate governance attributes, artificial intelligence, and corporate innovation. Adopting a new perspective, we have tried to help resolve the issue using a content analysis that integrates data from over 50 United States companies to analyze the relationship between board attributes, practice of artificial intelligence (AI) and firm innovation for the period 2018–2022. The results suggest that certain aspects of boards, such as board size, board diversity, and ownership concentration show the most significant correlations with firm AI development and innovation for overall industries, but the levels of associations also vary depending on different innovation measurements and samples considered in specific industries. Moreover, the mediating effects of AI and innovation are examined, respectively. Lastly, we also discovered changes in the industry’s attention to AI development before and after COVID-19 (2020). This research offers implications to corporate decision-makers as to how to proceed if the intent is to offer commercialized AI advancements and successful breakthrough innovations
Analysis of the long-term effects of the voluntary bid rule on Brazilian stock
Authors: Carvalhal Andre , Filho Jose Sanchez
Published: January 2024

The mandatory bid rule (also known as tag-along rights) is an important corporate governance mechanism that emerges in a company takeover and consists of acquirers granting non-controlling investors a price similar to the one made to the controlling shareholders. The goal of this research is to analyze if Brazilian companies that grant tag-along rights voluntarily have higher valuation and liquidity. We show evidence that the voluntary bid rule significantly affects common shares’ liquidity. In contrast, we find no significant relation between firm valuation and tag-along rights.

Authors: Reny W.A. Armalia
Published: January 2024

There was a dearth of empirical information and thorough understanding into how these strategies interacted and affected the performance of companies in the setting of Lampung Province before this research. Thus, this research investigates the effect of competitive and growth strategies on the strategic performance of companies registered with the Lampung Province Department of Industry and Trade. Utilizing a quantitative approach and statistical analysis of data from 396 survey respondents representing businesses across 15 cities and regencies in Lampung Province, the study employs the Partial Least Square (PLS) Structural Equation Modeling (SEM) method with SmartPLS software to analyze the data. The results indicate that competitive strategy significantly affects the strategic performance of companies. Additionally, growth strategy also significantly contributes to improved strategic performance, highlighting the importance of selecting the right growth strategies for companies. Simultaneously, both competitive and growth strategies exert a significant effect on the strategic performance of companies. These insights provide valuable guidance for businesses and regulatory authorities in Lampung Province's industrial and trade sectors, aiding them in designing more effective strategies to enhance company performance, considering both competitive and growth strategies.

Published: January 2024

The ability of rocks to hold a reliable record of the ancient
geomagnetic field depends on the structure and stability of magnetic
domain-states contained within the rock’s magnetic particles. In
paleomagnetic studies, the Day plot is an easily constructed graph of
magnetic hysteresis parameters that is frequently used (and mis-used) to
estimate the likely magnetic recording stability of samples. Often
samples plot in the region of the Day plot attributed to so-called
pseudo-single-domain (PSD) particles with little under standing of the
implications for domain-states or recording fidelity. Here we use
micromagnetic models to explore the hysteresis parameters of magnetite
particles with idealized prolate and oblate truncated-octahedral
geometries containing single domain (SD), single-vortex (SV) and
occasionally multi-vortex (MV) states. We show that these do main states
exhibit a well-defined trend in the Day plot that extends from the SD
region well into the multi-domain (MD) region, all of which are likely
to be stable remanence carriers. We suggest that although the
interpretation of the Day plot and its vari33 ants might be subject to
ambiguities, if the magnetic mineralogy is known, it can still provide
some useful insights about paleomagnetic specimens’ dominant domain
state, average particle sizes and, consequently, their paleomagnetic
stability.
Investigating Energy Transfer in the Atmosphere: Evaluating Gravity Wave Spectral Estimation Methods for Sparse Observational Datasets
Authors: Mossad Mohamed , Strelnikova Irina , Wing Robin , Baumgarten Gerd , Gerding Michael , Franco-Diaz Eframir
Published: January 2024

The accurate estimation of spectral power-law exponents (β) in
atmospheric gravity wave (GW) spectra plays a crucial role in
understanding energy transfer mechanisms within the atmosphere. However,
dealing with observational gaps in atmospheric measurements poses a
significant challenge for obtaining reliable estimations. Using
simulated data of varying complexity, we rigorously evaluate the
performance of these estimation methods and aim to offer valuable
guidance in selecting the most appropriate approach for accurately
determining β from observational datasets with gaps. Our findings are of
paramount importance for researchers, as they can significantly impact
our understanding of energy propagation and dissipation in the
atmosphere.

To further extend the scope and applicability of our investigation, we
have embarked on analyzing lidar measurements of temperatures and winds
in the stratosphere and mesosphere above Kühlungsborn (54°N, 12°E) and
ALOMAR (69°N, 16°E). By estimating the spectral power-law exponents of
atmospheric GWs in these distinct regions, we intend to shed light on
the energy transfer processes occurring during complex atmospheric
dynamics in the vicinity of the polar vortex.

This research aims to bridge the gap between theoretical predictions and
empirical findings in atmospheric science by providing robust
methodologies for accurate spectral estimation, even in the presence of
sparse observational data.
Modeling ionospheric TEC using gradient boosting based and stacking machine learning techniques
Authors: Shiferaw Ayanew , Tababal Ambelu , Galas Roman
Published: January 2024

Accurately predicting and modeling the total electron content (TEC) of
the ionosphere can greatly improve the accuracy of satellite navigation
and positioning and help to correct ionospheric delay. This study tested
the effectiveness of four different machine learning (ML) models in
predicting hourly vertical TEC (VTEC) data from a single station in
Addis Ababa, Ethiopia. The models used were gradient boosting machine
(GBM), extreme gradient boosting (XGBoost), light gradient boosting
machine (LightGBM) algorithms, and a stacked combination of these
algorithms with a linear regression algorithm. The models relied on
input variables that represent solar activity, geomagnetic activity,
season, time of the day, interplanetary magnetic field, and solar wind.
The models were trained using the VTEC data from January 2011 to
December 2018, excluding the testing data. The testing data comprised
the data for the year 2015 and the initial six months of 2017. The
RandomizedSearchCV algorithm was used to determine the optimal
hyperparameters of the models. The predicted VTEC values of the four ML
models were strongly correlated with the GPS VTEC, with a correlation
coefficient of $\sim$0.96, which is significantly
higher than the corresponding value of the International Reference
Ionosphere (IRI 2020) model, which is 0.87. Comparing the GPS VTEC
values with the predicted VTEC values based on diurnal and seasonal
characteristics showed that the predictions of the developed models were
generally in good agreement and outperformed the IRI 2020 model.
Overall, the GBDT-based algorithms and their stacked integration
demonstrated promising potential for predicting VTEC over Addis Ababa,
Ethiopia.

Published: January 2024

The Artemis exploration zone is a geologically-complex region likely
hosting some of the oldest and as-yet-unstudied materials on the Moon.
We review six potential Artemis landing sites (001, 004, 007, 011, 102,
and 105) within candidate Artemis III landing regions ‘Connecting
Ridge,’ ‘Peak Near Shackleton,’ ‘Leibnitz Beta Plateau,’ ‘de Gerlache
Rim,’ and ‘de Gerlache Rim 2.’ Kaguya Spectral Profiler mineral data
were used to determine average lithological composition at each landing
site. Potentially accessible geologic materials, their ages and
significance, and appropriate application of radiometric chronometers
are discussed in reference to return samples from each potential landing
site. Chronologic analyses of return samples from the Artemis
exploration zone will enable the anchoring of the lunar impact flux
curve, determine the absolute timing of pivotal events in lunar geologic
history, and reveal geological diversity of the differentiated lunar
body.
Dawn-dusk asymmetry in the main auroral emissions at Jupiter observed with Juno-UVS
Authors: Groulard A , Bonfond Bertrand , Grodent D , Gérard J.-C , Greathouse T K , Hue V , Gladstone G R , Versteeg M H
Published: January 2024

Jupiter’s main auroral emissions usually form auroral curtains surrounding the magnetic poles. Most explanations for this auroral feature are based on corotation enforcement currents flowing between the magnetosphere and the ionosphere. This process predicts the highest emitted power to originate from the dawn region, while the lowest emitted power would come from the noon to dusk region. However, a previous study using Hubble Space Telescope data showed the opposite, with a higher emitted power in the dusk region in the south and ambiguous results in the north. In the present study, we use data from the first 39 Juno perijoves to reexamine this question. We find a dusk region 3.3 to 5.5 times more powerful than the dawn one, in qualitative agreement with the previous study but contrary to theoretical expectations. These results support the idea that the main emissions cannot be fully described by corotation enforcement currents.

Winter methane fluxes over boreal and Arctic environments
Authors: Mavrovic Alex , Sonnentag Oliver , Lemmetyinen Juha , Voigt Carolina , Aurela Mika , Roy Alexandre
Published: January 2024

Unprecedented warming of Arctic–boreal regions (ABR) has poorly
understood consequences on carbon cycle processes. Uncertainties in
annual methane (CH4) budgets partly arise because of limited data
availability during winter. In this study, winter CH4 flux measurements
were conducted using the snowpack diffusion gradient method over five
ABR ecosystem types in Canada and Finland: closed–crown and open–crown
coniferous boreal forest, boreal wetland and erect–shrub and
prostrate–shrub tundra. Boreal forest uplands acted as net CH4 sinks,
while the boreal wetland acted as net CH4 source during winter. We
identified several wetland tundra CH4 emission hotspots and large
spatial variability in boreal wetland CH4 emissions. In the boreal
forest uplands, soil liquid water content was identified as an important
environmental control of winter CH4 fluxes. Our results indicate
non–negligible winter CH4 flux, which must be accounted for in annual
carbon balance and terrestrial biosphere models over ABR.

Published: January 2024

Climate extremes, such as hot temperature and heavy precipitation
events, have devastating effects on human societies. As the planet gets
warmer, they have become more intense and more frequent. To avoid
irreversible damages from climate extremes, many countries have
committed to achieving net-zero anthropogenic carbon emissions, or
carbon neutrality, by the 2050s. Here, we quantify the impact of carbon
neutrality on population exposure to climate extremes using multi-model
projections from the Coupled Model Intercomparison Project Phase 6
(CMIP6) Shared Socioeconomic Pathway (SSP)1-1.9 and SSP3-7.0 scenarios.
It is found that the increasing population exposure to hot-temperature
and heavy-precipitation extremes under SSP3-7.0 scenario can be
substantially reduced by 87–98% in the late 21st century by achieving
the carbon neutrality based on SSP1-1.9 scenario. The benefits of carbon
neutrality are particularly pronounced in Africa and Asia. The potential
benefits of carbon neutrality are also significant in North America,
Europe, and Oceania, where a reduction in climate extremes is more than
twice as important as population decline in reducing population exposure
to climate extremes. These results provide important scientific support
for ongoing efforts to achieve net-zero carbon emissions by the 2050s to
reduce potential climate risk and its inequity across continents.
Simulating Postfire Debris Flow Runout Using Morphodynamic Models and Stochastic Surrogates
Authors: Spiller Elaine T. , McGuire Luke A. , Patel Palak , Patra Abani , Pitman E. Bruce
Published: January 2024

Fire affects soil and vegetation, which in turn can promote the
initiation and growth of runoff-generated debris flows in steep
watersheds. Postfire hazard assessments often focus on identifying the
most likely watersheds to produce debris flows, quantifying rainfall
intensity-duration thresholds for debris flow initiation, and estimating
the volume of potential debris flows. This work seeks to expand on such
analyses and forecast downstream debris flow runout and peak flow depth.
Here, we report on a high fidelity computational framework that enables
debris flow simulation over two watersheds and the downstream alluvial
fan, although at significant computational cost. We also develop a
Gaussian Process surrogate model, allowing for rapid prediction of
simulator outputs for untested scenarios. We utilize this framework to
explore model sensitivity to rainfall intensity and sediment
availability as well as parameters associated with saturated hydraulic
conductivity, hydraulic roughness, grain size, and sediment entrainment.
Simulation results are most sensitive to peak rainfall intensity and
hydraulic roughness. We further use this approach to examine variations
in debris flow inundation patterns at different stages of postfire
recovery. Sensitivity analysis indicates that constraints on temporal
changes in hydraulic roughness, saturated hydraulic conductivity, and
grain size following fire would be particularly beneficial for
forecasting debris flow runout throughout the postfire recovery period.
The emulator methodology presented here also provides a means to compute
the probability of a debris flow inundating a specific downstream
region, consequent to a forecast or design rainstorm. This workflow
could be employed in scenario-based planning for postfire hazard
mitigation.

Published: January 2024

Synthetic downscaling of tropical cyclones (TCs) is critically important
to estimate the long-term hazard of rare high-impact storm events.
Existing downscaling approaches rely on statistical or
statistical-deterministic models that are capable of generating large
samples of synthetic storms with characteristics similar to observed
storms. However, these models do not capture the complex two-way
interactions between a storm and its environment. In addition, these
approaches either necessitate a separate TC size model to simulate storm
size or involve post-processing to introduce asymmetries in the
simulated surface wind. In this study, we present an innovative
data-driven approach for TC synthetic downscaling. Using a machine
learning-based high-resolution global weather model (ML-GWM), our
approach is able to simulate the full life cycle of a storm with
asymmetric surface wind that accounts for the two-way interactions
between the storm and its environment. This approach consists of
multiple components: a data-driven model for generating synthetic TC
seeds, a blending method that seamlessly integrate storm seeds into the
surrounding while maintain the seed structure, and a recurrent neural
network-based model for correcting the biases in maximum wind speed.
Compared to observations and synthetic storms simulated using existing
statistical-deterministic and statistical downscaling approaches, our
method shows the ability to effectively capture many aspects of TC
statistics, including track density, landfall frequency, landfall
intensity, and outermost wind extent. Taking advantage of the
computational efficiency of ML-GWM, our approach shows substantial
potential for TC regional hazard and risk assessment.
The 1871 Uprising in Rakovica as Seen by the Romanian Press in Transylvania and Hungary
Authors: Popovici Vlad
Published: January 2024

This study proposes a comparative analysis of the circulation of information between two peripheries of the Habsburg Monarchy (Croatia and Transylvania), respectively between a periphery and a center (Croatia and Pest), following the way in which the uprising in Rakovica in October 1871, together with its background and political connotations, were received, interpreted, and further transmitted to the Romanian-speaking public in Transylvania and Hungary by the Romanian press of the time. The objective of the study is to highlight the differences between the central and provincial press of an important ethnic group in Dualist Hungary, as well as to trace how a series of violent, unexpected, and potentially politically destabilizing events within one ethnic group were received and contextualized by the political elite of another ethnic group.

Do najpopularniejszych należą odchylenie standardowe, procedura EWMA i modele GARCH (p, q). Obliczenia wykonywane każdą z wymienionych metod mogą dawać odmienne wyniki. Celem artykułu jest ocena wpływu zmienności, w zależności od przyjętej metody szacowania, na przewidywane ceny zbóż otrzymywane w modelu dwumianowym. Badaniem objęto ceny zbóż w Polsce w okresie od 27.12.2004 do 25.04.2010 roku.

W opracowaniu przedstawiono wpływ dotacji z działania „Poprawa przetwórstwa i marketingu artykułów rolnych” z Sektorowego Programu Operacyjnego „Restrukturyzacja i modernizacja sektora żywnościowego oraz rozwój obszarów wiejskich” (SPO) na wyniki finansowe przedsiębiorstw przemysłu mięsnego, które skorzystały z tego wsparcia. Badaniami objęto 23 przedsiębiorstwa z wschodniej, centralnej i północno-wschodniej Polski (z województw: warmińsko-mazurskiego, podlaskiego, lubelskiego, mazowieckiego, łódzkiego i podkarpackiego), które podzielono na trzy grupy według kryterium wartości aktywów w roku bazowym 2004. Przeprowadzono analizę zysków i strat przedsiębiorstw w dwóch wariantach – z dotacją i bez dotacji. Na podstawie badań wykazano, że dotacje z SPO miały zróżnicowany wpływ na wyniki finansowe przedsiębiorstw. Pomoc finansowa część przedsiębiorstw (57%) uchroniła przed ujemnymi wynikami finansowymi lub zmniejszyła rozmiar poniesionych strat. Badania dowiodły również, że wielkość zysków netto pozostałych przedsiębiorstw (43%) pozwoliłaby im na dokonanie inwestycji w zakładanym zakresie bez otrzymania dotacji.
Economic Sciences: on the Autobahn, or on the Road to Nowhere?
Authors: Bronn Carl
Published: January 2024

Model building is a fundamental activity in economic science. Addressing the complexities of representing the real world has resulted in significant methodological advances, which in turn play an important role in furthering the field. However, what is not as well appreciated is that there is another type of modeling involved in this activity. While the econometric models are explicitly presented and open for inspection, the other model, called the mental model, is tacit, personal, and only rarely subjected to scrutiny. The two models are not independent, mental models define the framework within which the public econometric models are developed and understanding the nature of this interaction is important for the further development of economic sciences. There have are signals that the traditional approach to economic modeling is insufficient to meet the needs given current developments in understanding human behavior and policy analysis. The resistance to change has many possible causes, in this paper we briefly consider the role that mental models play in this development process and point to some alternative approaches that may be better suited to meet current modeling needs.

Interwencjonizm kredytowy w rolnictwie a problem dostępu rolników do kredytu bankowego
Authors: Kata Ryszard
Published: January 2024

Interwencjonizm kredytowy w rolnictwie jest przedmiotem analiz i ocen, które uzasadniają jego stosowanie lub przeciwnie ukazują niską efektywność tej polityki w realizacji jej celów makro- i mikroekonomicznych. W opracowaniu zaprezentowano niektóre argumenty teoretyczne oraz wyniki badań empirycznych, które odnoszą się do oceny interwencjonizmu kredytowego w rolnictwie z punktu widzenia jego wpływu na usuwanie barier w dostępie rolników do kredytu bankowego.
Środowiskowe aspekty planowanej reformy Wspólnej Polityki Rolnej
Authors: Kociszewski Karol
Published: January 2024

Celem artykułu jest identyfikacja potencjalnych kierunków zmian oddziaływania rolnictwa na środowisko w różnych wariantach reform wspólnej polityki rolnej (WPR). Na podstawie analizy wpływu potencjalnych zmian WPR na rozwój europejskiego rolnictwa w perspektywie do 2020 r., przedstawiono prawdopodobne konsekwencje planowanej reformy tej polityki w wymiarze środowiskowym. Uwzględniając dwie najważniejsze propozycje reformy, stwierdzono, że żadna z nich nie prowadzi do znaczącej liberalizacji polityki rolnej, co jest korzystne w świetle zrównoważonego rozwoju. Porównanie projektów przedstawionych przez Komisję Europejską i Parlament Europejski pozwala stwierdzić, że wdrożenie pierwszego z nich prowadziłoby do ekologizacji rolnictwa w szerszym zakresie. W propozycji Parlamentu nie przewiduje się daleko idących zmian, co oznacza, że w tym wariancie instrumenty ochrony środowiska byłyby skutecznie wdrażane, ale jedynie na części użytków rolnych. Równolegle duża część obszarów wykorzystywanych rolniczo podlegałaby dalszej intensyfikacji, więc zmiany WPR sprzyjałyby dwukierunkowemu rozwojowi rolnictwa i obszarów wiejskich.

Inwestowanie na rynku gruntów rolnych w Polsce
Authors: Laskowska Elwira
Published: January 2024

Celem badań jest określenie specyfiki rynku gruntów rolnych oraz charakterystyka głównych determinantów podejmowania decyzji inwestycyjnych na tym rynku. Wyniki badań wykazały, że na rynku gruntów rolnych, w porównaniu z innymi segmentami rynku nieruchomości, niższy jest poziom stopy zwrotu mierzonej ilorazem rocznych dochodów z czynszów z tytułu dzierżawy do ceny gruntu. Pomimo tego, w ostatnich latach utrzymywał się popyt na grunty rolne oraz tendencja wzrostowa ich cen, czego nie notowano na rynkach innego rodzaju nieruchomości. Dowodzi to istnienia innych czynników niż uzyskiwanie dochodów z nieruchomości z tytułu dzierżawy, wpływających na podejmowanie decyzji inwestycyjnych na tym rynku.
Regionalne zróżnicowanie wykorzystania środków z programów Wspólnej Polityki Rolnej na modernizację rolnictwa
Authors: Wicki Ludwik , Pietrzykowski Robert
Published: January 2024

Celem artykułu jest przedstawienie regionalnego zróżnicowania natężenia wykorzystania środków w ramach działań wspólnej polityki rolnej (WPR) przeznaczanych na modernizację gospodarstw rolniczych. Badaniami objęto okres 2004-2009. Użyto dane ARiMR dotyczące realizacji poszczególnych działań oraz dane GUS. W badaniach wykorzystano takie wskaźniki, jak: liczba wniosków na 1000 gospodarstw, wartość wsparcia na 1 gospodarstwo i na 1 ha użytków rolnych. Dla podziału województw na grupy wykorzystano metodę analizy skupień. Stwierdzono, że występują znaczne różnice w wykorzystaniu środków. Najsłabsze ich wykorzystanie miało miejsce w 7 województwach na południu Polski, najwyższe zaś w województwach kujawsko-pomorskim i wielkopolskim. Podstawowym czynnikiem związanym z niskim wykorzystaniem dotacji na modernizację gospodarstw była mała powierzchnia gospodarstw. Środki na modernizację gospodarstw pozyskiwane były głównie przez rolników z gospodarstw większych obszarowo, a więc w województwach o wyższej przeciętnej powierzchni gospodarstwa. Środki te w małym stopniu pozwalały na przyśpieszanie przemian w strukturze agrarnej w regionach z dominacją drobnych gospodarstw rolnych.
Bariery wprowadzania innowacji w przedsiębiorstwach przetwórstwa spożywczego w Polsce w latach 2002-2010
Authors: Nieć Melania
Published: January 2024

Przedstawiono czynniki utrudniające działalność innowacyjną w przedsiębiorstwach branży spożywczej. Przy wykorzystaniu metod statystycznych zbadano, czy istnieje zależność między wielkością przedsiębiorstwa a stopniem wpływu czynników utrudniających działalność innowacyjną oraz wskazano najistotniejsze bariery w grupach przedsiębiorstw według wielkości. Do badania wykorzystano zarówno dane powszechnie dostępne z GUS, jak i niepublikowane dane pochodzące z trzech okresów badawczych: 2002-2004, 2004-2006 i 2008-2010. Badania wykazały m.in., że działalność innowacyjna przedsiębiorstw spożywczych jest hamowana głównie przez czynniki ekonomiczne, a znaczenie tych czynników maleje wraz ze wzrostem rozmiaru przedsiębiorstwa.
Poziom kapitału obrotowego a możliwości generowania kapitału finansowego w rodzinnych gospodarstwach rolniczych
Authors: Bereżnicka Joanna
Published: January 2024

W opracowaniu dokonano oceny zdolności generowania kapitału finansowego (środków pieniężnych) w rodzinnych gospodarstwach rolnych w zależności od poziomu kapitału obrotowego netto. Badaniami objęto gospodarstwa uczestniczące w systemie zbierania danych polskiego FADN w latach 2004-2008. Zastosowano podział według kwartyli. Gospodarstwa o dużym kapitale obrotowym wykazywały znacznie większe możliwości w zakresie generowania środków pieniężnych, ale coraz wyższą efektywność w tym zakresie realizowały gospodarstwa z dolnego kwartyla.
Rynek chryzantem w Polsce w okresie Święta Wszystkich Świętych
Authors: Jabłońska Lilianna , Sobczak Wioleta
Published: January 2024

Rynek kwiaciarski w Polsce cechuje się bardzo dużym zapotrzebowaniem na chryzantemy do dekoracji grobów w okresie święta Wszystkich Świętych. Wzrost popytu w ostatnich 20 latach spowodował wzrost ich produkcji, która jest prowadzona na około 800 ha pod osłonami. Konkurencją dla producentów chryzantem stają się jednak coraz powszechniej stosowane w dekoracjach nagrobków sztuczne kwiaty. W opracowaniu podjęto próbę oceny tego zagrożenia oraz scharakteryzowania zmian w popycie i preferencjach konsumentów odnośnie rodzaju, form i kolorystyki żywych chryzantem. W badaniach wykorzystano wyniki badań ankietowych prowadzonych w latach 2009 i 2010 wśród producentów roślin, hurtowników oferujących sztuczne kwiaty, konsumentów oraz wyniki badań 6 nekropolii.

Authors: Grużewska Agata , Brzozowski Piotr , Majchrowski Karol , Rymuza Katarzyna
Published: January 2024

W pracy przedstawiono opłacalność produkcji czarnej porzeczki według cen z 2010 roku. Przedstawiono koszty założenia plantacji i jej użytkowania w okresie inwestycyjnym oraz koszty ponoszone w okresie pełnego owocowania. Przeprowadzono również ocenę zmiany opłacalności produkcji w zależności od ceny i uzyskanego plonu. Stwierdzono, że uprawa czarnej porzeczki staje się nieopłacalna, jeśli cena wynosi 1,3 zł za kg, a plon - 4 tony z hektara.
Organizacja i ekonomika produkcji mleka w Polsce, dotychczasowe tendencje i kierunki zmian
Authors: Ziętara Wojciech
Published: January 2024

W artykule przedstawiono udział produkcji mleka w Polsce w latach 2000-2010 w strukturze towarowej produkcji rolniczej oraz zmiany poziomu i relacji między kosztami podstawowych czynników produkcji, pracy i kapitału a cenami zbytu produktów rolnych oraz pogarszającą się jednostkową opłacalność produkcji rolniczej, w tym także mleka. Dokonano oceny ekonomiki gospodarstw mlecznych w zależności od skali produkcji. Wskazano, że decydującym czynnikiem rozwoju gospodarstw mlecznych jest skala produkcji mleka. Szanse rozwojowe mają gospodarstwa mleczne utrzymujące ponad 30 krów mlecznych o wydajności rocznej ponad 5500 kg. Dokonano porównań efektów produkcyjnych i ekonomicznych gospodarstw z Polski i innych państw Unii Europejskiej nastawionych na produkcję mleka.
