Published: April 2023

The highest way to protect data from intruder and unauthorized persons has become a major issue. This matter led to the development of many techniques for data security, such as Steganography, Cryptography, and Watermarking to disguise data. This paper proposes an image steganography method using the Least Significant Bits (LSB) technique and XOR operator and a secret key, through which the secret key is transformed into a one-dimensional bit stream array, then these bits are XORed with the bits of the secret image. Multiple experiments have been performed to embed color and grayscale images inside cover media. In this work, the LSB technique is ideal in two ways: firstly, only the least significant one-bit (1bit) of each byte will store the embedded data, this method is named (1-LSB). Secondly, the four least significant bits of the right half-byte (4 bits) of each byte will store the embedded data, this method is named (4-LSB). Subjective and objective analyzes were performed for each LSB process. The subjective analysis is responsible for both HVS and histogram, whereas the objective analysis involved both PSNR and MSE metrics.

Published: April 2023

Information and Communication Technology (ICT) has been identified as a vehicle with the potential to improve the quality of health care systems as well as the efficiency of the health workers both in the developed and developing countries. Non-governmental organizations initiatives often fail in making use of ICT technology possibly due to lack of ICT knowledgeable and skilled personnel in the health sector. This study investigates the potentials of information and communication technology (ICT) adoption by health workers in Nigeria. Quantitative survey was used to collect data from randomly chosen health workers at Abdullahi Wase Specialist Hospital Kano in Nigeria. A total of 150 on-paper questionnaires were distributed among clinical and non-clinical staff and 140 (93.3%) questionnaires were collected and analysed using a modified technology acceptance model (TAM). The results showed that there is significant correlation between the knowledge (dependent variable) and perceive usefulness and perceive ease of use (independent variables) both at significant level of 0.05. This indicates that presence of prior computer knowledge and exposure has significant influence on health workers perceptions (perceive usefulness and perceive ease of use), overall attitude toward adoption and eventually usage of information and communication technologies. This indicates that knowledge and attitude scores of health workers in this study reflect progress despite the lack of institutional training.

Iteration and recursion are very pivotal concepts in understanding the logic and building blocks of all computer programs across all programming paradigms. Although the theory of iteration together with the development and implementation of iterative algorithm is easy to grasp, that of recursion remains elusive to programmers especially novice programmers. In this research, functions composition is applied in the explanation of iteration using recursion. The method demonstrates an easy and elaborate way of writing iterative programs using recursion by identifying the significant variables in both constructs. Function composition is used to write the recursive function, the recursive variable is identified as a variable that converges towards the base case, also the base case is also identified as being the terminating point of the function call else the function call runs and fill the stack memory causing stack overflow. The recursive part is the loop update and base case the termination condition in iterative programs. The results obtained simplifies how to write iterative codes using recursion.
Sociocultural Relations: Perspectives from Covid-19 Newspaper Headlines
Authors: Okoye Adaobi Ngozi , Adioha Justice Ekenedirichukwu
Published: April 2023

Since the outbreak of the novel coronavirus pandemic in the world as a terminal disease, different lexical items have been adopted by Nigerian News Editors in rendering news reports on the pandemic. Certainly, power and significance are embedded in these news reports and these headlines help to reveal hidden sociocultural ideologies. Thus, the present study investigates selected Covid-19 newspaper headlines in order to ascertain how newspaper headlines have been used to illuminate hidden sociocultural ideologies. The study adopts Fairclough's (1995) theory of Critical Discourse Analysis as a sociocultural practice where emphasis is made on the three dimensions (3Ds) of discourse analysis namely description, interpretation and explanation.Covid-19 newspaper headlines selected from five Nigerian Newspapers namely the Guardian, Daily Trust, Nation, Tribune and Punch newspapers are analysed thematically in a bid to ascertain how the choice of words by the editors have been used to reveal hidden ideologies. A critical analysis of the headlines reveals a covert underlying social and cultural motivation for the readers’ consumption. The study further shows that covid-19 newspaper headlines perform myriads of functions from the perspective of the readers as they have implications on the social, political, economic and religious life of the readers. It can be concluded that these headlines reshape the readers’ mind-set.

A will in the drawers. On the sidelines of a new translation of Sodom and Gomorrah Written on the sidelines of a new translation of Sodom and Gomorrah into Polish, the article evokes the problem that the translator had in finding the equivalent of the term inverti. This problem serves as a pretext to speak, on the one hand, of homosexuality in Proust, on the other, of language as the subject of the novel. In this context, the role of Albertine and the etymological tirades of professor Brichot are studied in particular. The author also highlights the testamentary character of this part of the Proustian cycle.

Análisis jurisprudencial de las enfermedades del trabajo cardiovasculares y hemorragias cerebrales
Authors: Legua Rodrigo Maria Carmen
Published: April 2023

El concepto de enfermedad profesional establecido en nuestro ordenamiento jurídico, en el art. 157 LGSS, remite a una lista oficial, por tanto, solo es enfermedad profesional la que se encuentra listada. Esto presenta importantes inconvenientes dado que las patologías que no están incluidas en el cuadro no se pueden calificar como enfermedad profesional.

Por tanto, ante la dificultad del sistema lista cerrada, para determinar una enfermedad profesional ha sido necesario buscar otras alternativas, con la finalidad de que determinados supuestos quedasen protegidos con las particularidades de las enfermedades profesionales.

Tanto la jurisprudencia como la doctrina científica ha admitido la contingencia profesional del infarto de miocardio, las cardiopatías isquémicas, los derrames cerebrales, el ictus. En el presente trabajo se procede a analizar la calificación y su consideración como accidente de trabajo de estas enfermedades por la jurisprudencia.

Se puede calificar de profesional la enfermedad cardiovascular, los derrames cerebrales cuando se exterioricen en tiempo y lugar de trabajo, también se reconocen como contingencia profesional las enfermedades de aparición súbita.

La especial consideración de las enfermedades cardiovasculares, derrames cerebrales producidos en los vestuarios, en el garaje y en el tiempo del descanso para el bocadillo, serán objeto de análisis en el presente ensayo, así como las ocurridas in itinere y in misión.

Por otra parte, presentan dificultad para calificarlas las enfermedades que se producen fuera del tiempo y lugar de trabajo, ofreciendo una enorme casuística.

Nigeria’s federalism has been contending with severe working and constitutional/institutional challenges. These challenges which range from political to
economic and social has resulted in the vociferation for the political restructuring and rearrangement of the country. The inability of the country to espouse
and practice federalism effectively which is indicated in the over-centralization of powers/functions on the central government has brought ethnic conflicts,
political turmoil, marginalization of some ethnic groups, corruption, lack of good governance instead of peace, development and administrative ease. This
study, therefore, investigates if the failure to address the geographical imbalance in representation accounts for the rise in secessionist agitations and tension
in Nigeria, with its focus on the separatist agitations amongst the Igbo indigenous group in south-eastern Nigeria. The modern classic theory of federalism
was adopted as our theoretical framework. The documentary method of data collecting and the qualitative descriptive approach of data analysis were both
used in the study. This study revealed that although Nigeria federalism was purposely adopted by the foundational policymakers to purportedly eradicate
ethnic dominance and inspire the component units to progress and advance at a different speed, The establishment of an unjust, imbalanced, and hypercentralized federal structure during the previous military administration did countless harms to the foundational elements of Nigeria’s federal system by
promoting ethnic dominance and submitting the constituent units to the financial hegemony of the center. The Igbos of the South-East region of Nigeria has
been the victim of this hyper-centralized federal structure and ethnic subjugation over the years, hence, the incessant rise in the emergence and activities
of separatist and pro-independence movements in the region. Consequently, the study recommended an all-inclusive restructuring and reorganization
of the political system of Nigeria by adopting a firm, even and appropriate Federal composition that will encompass state or regional independence and
autonomy when it concerns governmental powers and fiscal resources

Systematic Objectification of Eastern Women in Western Society A Case Study of ‘The Optimist’ by Bina Shah
Authors: Lashari Sajid
Published: April 2023

Patriarchy is deeply rooted in all societies of the world and many sociological, political and religious reasons are behind this ideology. This was not highlighted by western writers in the past but it exists in the western modern world is also as presented by Loius Tyson (2006). He has claimed that women are kept oppressed economically, politically, socially and psychologically by patriarchy, moreover, women are considered as the ‘other’, therefore objectified and marginalized. The writings of eastern writers like the short story ‘The Optimist’ written by Bina Shah verifies the claims of Tyson. The narrated story proves that oppression of women is not the issue of eastern western society but it is a universal problem that has strong roots in the societies of the men dominating societies. Pakistani writers have always tried to expose such ideologies through their writings, which allegedly justify the dominance of men over women. Human relations are reciprocal and cannot be directed from one side. The approach employed is qualitative with techniques of textual and thematic analysis keeping claims in mind, presented by Lois Tyson in his book Critical Theory Today. It was found, through the analysis of the story, that women are oppressed economically, politically, socially, and psychologically and they are treated as the ‘other’: objectified and marginalized, by men not only in the east but all over the world. However, the element of ‘revolt against biased ideologies’ is also very significant through the rebellious behavior of the character and emphasizes bringing change in the societies.
Determinants of Climate Change Adaptation Strategies in Bundelkhand Region, India
Authors: Jatav Surendra Singh , Singh Naveen Prakash
Published: April 2023

The study attempted examining climate change adaptation strategies in the most backward regions of India, i.e., the Bundelkhand region. Data were collected from 200 farmers during April and May of 2017, and a binary logistic regression model was used to analyze the data. The farmers were most likely to improve irrigation facilities if they have access to institutional credit, information about the weather, and have taken crop insurance. Also, farmers perceived that an increase in temperature, a decline in rainfall, and a decline in water tables motivate and influence farmers to change their cropping pattern from wheat (a water-intensive crop) to chickpea (a less water-intensive crop) to cope with the changing climate. Hence, the present study recommends that since water table is declining continuously and creating water crisis even in the rainy season for agriculture and domestic consumption, community participation in the conservation of water-bodies is vital. Further, the adoption of crop varieties that require less water, are drought tolerant and mature early will help increase farm productivity and reduce cultivation costs. Lastly, an advance regional weather forecasting system capable of providing farmers with accurate information that will enable them to change cropping patterns and adjust farming practices are required.

Published: April 2023

To mitigate and cope with changing climate, adaptation strategies are essential. However, farmers are facing several constraints while adapting to the changing climate. The study was conducted during 2018-19 in three major paddy growing districts of Kalyana Karnataka region of Karnataka state with 90 respondents. The Rank Based Quotient (RBQ) approach was used to assemble, tabulate, and evaluate the data. The farmers expressed the absence of a location-specific climate forecast and they couldn’t able to rely on available climate forecasts. In addition, farmers opined about the non-availability of critical inputs and fair prices for their produce. It suggested the farmers of the study region should be provided with updated and reliable information on climate change as this could help in improving their awareness on changing climate. The improvement of field extension connectivity and timely assistance to the farmers are required for better utilization of resources and adoption of climate-related strategic innovations.

Published: April 2023

The tomato is the most consumed vegetable in raw or processed form in every house and its demand is throughout the year. The present study was carried out in the Kurukshetra, Karnal, and Yamunanagar Districts of Haryana in 2022-23. The data was collected from a sample of 210 farmers with the help of a well-structured interview schedule with the objective to study the constraints faced at the production and marketing levels. The analysis of data was done with the Garrett ranking technique. The study concluded that the major problem at the production level was climate vagaries (79.01), high labor cost (74.60), high incidence of insect, pest, and disease (70.52), high cost of tomato seed (62.75) and lack of skilled labor during peak time (59.79). At the marketing level, frequent price fluctuation (82.90), lack of cold storage and warehouse facilities (72.38), high transportation cost (68.83), and quality deterioration during transportation (61.07) were found to be major constraints. Extension programs focused on creating awareness among farmers on prevailing schemes, subsidies and hi-tech farming methods such as controlled climate production can be helpful in overcoming the constraints.

Τ-quasi-Cauchy spaces - a non-symmetric theory of completeness and completion
Authors: Jäger Gunther
Published: April 2023

Based on the concept of Cauchy pair Τ-filters, we develop an axiomatic theory of completeness for non-symmetric spaces, such as Τ-quasi-uniform (limit) spaces or L-metric spaces. We show that the category of Τ-quasi-Cauchy spaces is topological and Cartesian closed and we construct a finest completion for a non-complete Τ-quasi-Cauchy space. In the special case of symmetry, Τ-quasi-Cauchy spaces can be identified with Τ-Cauchy spaces.
Is the second generation of transmigrants more prosperous? A study of intergenerational welfare in ex-transmigration settlements
Authors: Yulmardi Yulmardi , Junaidi Junaidi , Nugraha Putra Dios
Published: April 2023

Purpose. This study aims to analyze: (1) the characteristics of the second generation of transmigrants; (2) the welfare of the second generation compared to the first generation.

Methodology / approach. The research setting is two villages in Rimbo Bujang District, Tebo Regency, Jambi Province, Indonesia. The population of this study consists of second-generation transmigrant families over the age of 20 or married. A simple random sampling method determined the sample. The number of samples is 40 respondents for each selected village; the total sample is 80 respondents for the second generation and 80 for the first generation. A descriptive analysis was conducted with the help of single and cross-frequency tables.

Results. The welfare of the second generation is improved compared to the first generation. The study found that land fragmentation occurred in transmigrant families, but this did not cause a decrease in welfare, as there are job opportunities outside the agricultural sector and land fragmentation already within the family. The second generation of transmigrants can take advantage of these job opportunities outside the agricultural sector because their education is better than the first generation.

Originality / scientific novelty. The scientific novelty of this research is related to the object of research, namely the welfare of transmigrant descendants. So far, research on transmigration has focused more on the first generation of transmigration and the macro aspects of the transmigration program.

Practical value / implications. The government is recommended to facilitate and create a favorable investment climate so that non-agricultural business activities in transmigration villages can develop better. The development of these non-agricultural activities will open up new job opportunities and be able to eliminate the decline in welfare due to the fragmentation of land within the family.

Authors: Liang Rui
Published: April 2023

Purpose. The purpose of this study is to how the university brand wins the psychology of college students, and discusses the decision-making behavior of college students’ school choice and university brand based on consumer psychology.

Results. According to the results of the analysis, university brand wins the consumer psychology of college students through university brand value. The key factor that university brand affects the consumption psychology of college students is that education is regarded as the primary purpose of the brand. University brand is carried by people, and students and staff are the significant identification of university brand image and the fundamental guarantee of establishing this brand. University brand is a kind of brand that needs late effect evaluation. University brand reflects the educational quality and characteristics of the university, reflects the social reputation of the university, and represents the employment prospects of graduates. The university brand represents competitiveness. College students, as consumers, will consider the influence of college brand on future employment, and their choice of college will also affect its brand. College students’ brand selection can be divided into three time points and four development stages.

Scientific novelty. This article combines knowledge related to psychology and management, thus contributing to an interdisciplinary understanding of the university brand; analyzing many products, consumers cannot accept all of them, so the brand plays an important role in the consumer behavior of students.

Practical value. This article analyzes how university brand wins the psychology of college students, the key factors for the university brand to win the psychology of college students, and discusses the decision-making behavior of college students’ school choice and university brand based on consumer psychology. The strategy provides a certain theoretical basis.
Analysis of new particle formation events and comparisons to simulations of particle number concentrations based on GEOS-Chem–advanced particle microphysics in Beijing, China
Authors: Wang Kun , Ma Xiaoyan , Tian Rong , Yu Fangqun
Published: April 2023

Abstract. Aerosol particles play important roles in air quality and
global climate change. In this study, we analyze the measurements of
particle size distribution from 12 March to 6 April 2016 in Beijing to
characterize new particle formation (NPF) using the observational data of
sulfuric acid, meteorological parameters, solar radiation, and the mass concentration of fine
particles (PM2.5, particulate matter with diameters less than 2.5 µm). During this 26 d campaign, 11 new particle
formation events are identified with obvious bursts of sub-3 nm particle
number concentrations and subsequent growth of these nucleated particles. It
is found that sulfuric acid concentration in Beijing does not have a
significant difference between NPF event and non-event days. Low relative humidity
(RH) and high daily total solar radiation appear to be favorable for the
occurrence of NPF events, which is quite obvious in this campaign. The
simulations using four nucleation schemes, i.e., H2SO4–H2O
binary homogeneous nucleation (BHN), H2SO4–H2O–NH3
ternary homogeneous nucleation (THN), H2SO4–H2O–ion binary
ion-mediated nucleation (BIMN), and H2SO4–H2O–NH3–ion
ternary ion-mediated nucleation (TIMN), based on a global chemistry
transport model (GEOS-Chem) coupled with an advanced particle microphysics
(APM) model, are conducted to study the particle number concentrations and
new particle formation process. Our comparisons between measurements and
simulations indicate that the BHN scheme and BIMN scheme significantly
underestimate the observed particle number concentrations, and the THN
scheme captures the total particle number concentration on most NPF
event days well but fails to capture the noticeable increase in particle number
concentrations on 18 March and 1 April. The TIMN scheme has obvious
improvement in terms of total and sub-3 nm particle number concentrations
and nucleation rates. This study provides a basis for further understanding
of the nucleation mechanism in Beijing.

Abstract. Eastern boundary upwelling systems (EBUS) contribute a disproportionate
fraction of the global fish catch relative to their size and are especially
susceptible to global environmental change. Here we present the evolution of
communities over 50 d in an in situ mesocosm 6 km offshore of Callao, Peru, and
in the nearby unenclosed coastal Pacific Ocean. The communities were
monitored using multi-marker environmental DNA (eDNA) metabarcoding and flow
cytometry. DNA extracted from weekly water samples were subjected to
amplicon sequencing for four genetic loci: (1) the V1–V2 region of the 16S
rRNA gene for photosynthetic eukaryotes (via their chloroplasts) and
bacteria; (2) the V9 region of the 18S rRNA gene for exploration of
eukaryotes but targeting phytoplankton; (3) cytochrome oxidase I (COI) for
exploration of eukaryotic taxa but targeting invertebrates; and (4) the 12S
rRNA gene, targeting vertebrates. The multi-marker approach showed a
divergence of communities (from microbes to fish) between the mesocosm and
the unenclosed ocean. Together with the environmental information, the
genetic data furthered our mechanistic understanding of the processes that
are shaping EBUS communities in a changing ocean. The unenclosed ocean
experienced significant variability over the course of the 50 d experiment,
with temporal shifts in community composition, but remained dominated by
organisms that are characteristic of high-nutrient upwelling conditions
(e.g., diatoms, copepods, anchovies). A large directional change was found in
the mesocosm community. The mesocosm community that developed was
characteristic of upwelling regions when upwelling relaxes and waters
stratify (e.g., dinoflagellates, nanoflagellates). The selection of
dinoflagellates under the salinity-driven experimentally stratified
conditions in the mesocosm, as well as the warm conditions brought about by
the coastal El Niño, may be an indication of how EBUS will respond under
the global environmental changes (i.e., increases in surface temperature and
freshwater input, leading to increased stratification) forecast by the IPCC.

Abstract. Heavy precipitation over western Germany and neighboring countries in July 2021 led to widespread floods, with the Ahr and Erft river catchments being particularly affected. Following the event characterization and process analysis in Part 1, here we put the 2021 event in the historical context regarding precipitation and discharge records and in terms of the temporal transformation of the valley morphology. Furthermore, we evaluated the role of ongoing and future climate change on the modification of rainfall totals and the associated flood hazard, as well as implications for flood management. The event was among the five heaviest precipitation events of the past 70 years in Germany. However, consideration of the large LAERTES-EU regional climate model (RCM) ensemble revealed a substantial underestimation of both return levels and periods based on extreme value statistics using only observations. An analysis of homogeneous hydrological data of the last 70 years demonstrated that the event discharges exceeded by far the statistical 100-year return levels. Nevertheless, the flood peaks at the Ahr river were comparable to the reconstructed major historical events of 1804 and 1910, which were not included in the flood risk assessment so far. A comparison between the 2021 and past events showed differences in terms of the observed hydro-morphodynamic processes which enhanced the flood risk due to changes in the landscape organization and occupation. The role of climate change and how the 2021 event would unfold under warmer or colder conditions (within a −2 to +3 K range) was considered based on both a pseudo global warming (PGW) model experiments and the analysis of an RCM ensemble. The PGW experiments showed that the spatial mean precipitation scales with the theoretical Clausius–Clapeyron (CC) relation, predicting a 7 % to 9 % increase per degree of warming. Using the PGW rainfall simulations as input to a hydrological model of the Ahr river basin revealed a strong and non-linear effect on flood peaks: for the +2 K scenario, the 18 % increase in areal rainfall led to a 39 % increase of the flood peak at gauge Altenahr. The analysis of the high-resolution convection-permitting KIT-KLIWA RCM ensemble confirmed the CC scaling for moderate spatial mean precipitation but showed a super CC scaling of up to 10 % for higher intensities. Moreover, the spatial extent of such precipitation events is also expected to increase.

Abstract. Snowmelt runoff serves both human needs and ecosystem services and is an important parameter in operational forecasting systems. Sentinel-1
synthetic-aperture-radar (SAR) observations can estimate the timing of melt within a snowpack; however, these estimates have not been applied on
large spatial scales. Here we present a workflow to combine Sentinel-1 SAR and optical data from Landsat-8 and Sentinel-2 to estimate the onset and
duration of snowmelt in the La Joie Basin, a 985 km2 watershed in the southern Coast Mountains of British Columbia. A backscatter threshold is used to
infer the point at which snowpack saturation occurs and the snowpack begins to produce runoff. Multispectral imagery is used to estimate snow-free
dates across the basin to define the end of the snowmelt period. SAR estimates of snowmelt onset form consistent trends in terms of elevation and aspect on
the watershed scale and reflect snowmelt records from continuous snow water equivalence observations. SAR estimates of snowpack saturation are most
effective on moderate to low slopes (< 30∘) in open areas. The accuracy of snowmelt duration is reduced due to persistent cloud cover in
optical imagery. Despite these challenges, snowmelt duration agrees with trends in snow depths observed in the La Joie Basin. This approach has high
potential for adaptability to other alpine regions and can provide estimates of snowmelt timing in ungauged basins.
