Cardiorespiratory response patterns during multifunctional imagery-assisted biofeedback training – a case study
Authors: Roy Jolly , Athrey Aravind , Xavier Cheryl , Sonar Samruddhi
Published: February 2024

Objectives

The study aimed to expand the knowledge of cardiorespiratory response patterns while engaging in multifunctional imagery-assisted biofeedback training in a young cricketer.

Methods

The athlete was asked to engage in imagery (e.g. facing the bowler in an over: six ball) and cardiorespiratory responses were monitored using biofeedback equipment. The study involved a total of 19 sessions. Phases 1 & 2 focused on need analysis and action plan respectively and phases 3 to 5 focused on imagery–assisted biofeedback training viz. Motivational Specific-MS (six sessions); Motivational General-Mastery MG-M (six sessions); Cognitive Specific-CS-PETTLEP (7 sessions). The qualitative feedback was taken after each session from phases 3 to 5.

Results

A higher heart rate (HR) was observed while facing the second ball in an over during MS (83 % of the time) and MG-M type of imagery (50 % of the time). While doing CS imagery, the higher HR was observed while facing the fifth ball in an over (57 % of the time). No consistent pattern was observed in the respiration rate (RR) while engaging in imagery training. The athlete’s feedback revealed that in MS and MG-M, the initial attention was on staying focused while facing the bowler. During the CS imagery, the difference in the HR patterns probably happened because the athlete focused on appropriate skill execution.

Conclusions

Understanding an athlete’s cardiorespiratory patterns can be helpful in training an athlete's self-regulation to reach the optimal zone of functioning.
Differential experiments using parallel alternative operations
Authors: Calderini Marco , Civino Roberto , Invernizzi Riccardo
Published: February 2024

The use of alternative operations in differential cryptanalysis, or alternative notions of differentials, is lately receiving increasing attention. Recently, Civino et al. managed to design a block cipher that is secure with respect to the classical differential cryptanalysis performed using XOR-differentials, but weaker with respect to the attack based on an alternative difference operation acting on the first s-box of the block. We extend this result to parallel alternative operations, i.e. acting on each s-box of the block. First, we recall the mathematical framework needed to define and use such operations. After that, we perform some differential experiments against a toy cipher and compare the effectiveness of the attack with respect to the one that uses XOR-differentials.

Published: February 2024

We study the optimal performance of an endoreversible quantum dot heat engine, in which the heat transfer between the system and baths is mediated by qubits, operating under the conditions of a trade-off objective function known as the maximum efficient power function defined by the product of power and efficiency of the engine. First, we numerically study the optimization of the efficient power function for the engine under consideration. Then, we obtain some analytic results by applying a high-temperature limit and compare the performance of the engine at maximum efficient power function to the engine operating in the maximum power regime. We find that the engine operating at maximum efficient power function produces at least 88.89 % of the maximum power output while at the same time reducing the power loss due to entropy production by a considerable amount. We conclude by studying the stochastic simulations of the efficiency of the engine in maximum power and maximum efficient power regime. We find that the engine operating at maximum power is subjected to fewer power fluctuations as compared to the one operating at maximum efficient power function.

Authors: Expósito Raspeño Mónica , Sánchez Escudero Verónica , Pérez de Nanclares Leal Guiomar , Ortiz Santamaría María , Sánchez-Dehesa Sáez Rosa , García Cuartero Beatriz , González Vergaz Amparo
Published: February 2024

Objectives

Pseudohypoparathyroidism type 1A (PHP1A) encompasses the association of resistance to multiple hormones, features of Albright hereditary osteodystrophy and decreased Gsα activity. Little is known about the early signs of PHP1A, with a delay in diagnosis. We report two PHP1A cases and their clinical and biochemical findings during a 20-year follow-up.

Case presentation

Clinical suspicion was based on obesity, TSH resistance and ectopic ossifications which appeared several months before PTH resistance, at almost 3 years of age. Treatment with levothyroxine, calcitriol and calcium was required in both patients. DNA sequencing of GNAS gene detected a heterozygous pathogenic variant within exon 7 (c.569_570delAT) in patient one and a deletion from XLAS to GNAS-exon 5 on the maternal allele in patient 2. In patient 1, ectopic ossifications that required surgical excision were found. Noticeably, patient 2 displayed adult short stature, intracranial calcifications and psychomotor delay. In terms of weight, despite early diagnosis of obesity, dietary measures were established successfully in both cases.

Conclusions

GNAS mutations should be considered in patients with obesity, ectopic ossifications and TSH resistance presented in early infancy. These cases emphasize the highly heterogeneous clinical picture PHP1A patients may present, especially in terms of final height and cognitive impairment.
The traumatic narratives of sexuality in Taiwanese writer Shao-Lin Chu’s trilogy
Authors: Tsai Hsiu-Chih
Published: February 2024

This paper explores the narratives of the Taiwanese woman novelist Shao-Lin Chu’s trilogy to see how the problem of female sexuality and resistance to parental wedlock tragedy becomes a traumatic experience. The traumatic symptoms in the narratives are taken as Peircean signs for tracing the negative influences of traumatic experiences on the formation of personal identity and the associated depressive disorder. The scenes portrayed in Chu’s traumatic narratives of female and male sexuality are implications and representations of how sexuality is conceptualized and confined by the traumatic events while backgrounded with regulations and restrictions of a traditional society. The stories of Chu’s female narrators reveal the persistent and resisting feminine power. This paper adopts the concept of feminist narrative to analyze the traumatic and sexual events in Chu’s trilogy. The decoding and re-encoding of resistance and sexuality in the traumatic narratives prove that the narratological textual analysis and semiotic reading strategy together offer a solid approach to the discovery of the persistent traumatic impacts of the secret veiled in the narratives and reveal the probable strength of compassion that has its roots derived from deplorable trauma but later transforms itself to stimulate a positive reconstruction of the traumatic survivors’ identity.
Null and overt se constructions in Brazilian Portuguese and the network of se constructions
Authors: Afonso Susana , Soares da Silva Augusto
Published: February 2024

Middle voice (MV) comprises a set of marked constructions associated with situation types (Kemmer 1993. The middle voice. Amsterdam: John Benjamins), in which the middle marker functions as an intransitivizer. MV constructions in Portuguese are se constructions in which the clitic se is typically overt, but in Brazilian Portuguese there is variation between constructions with and without the clitic marker. The overt-null variation is observed in all se construction types and it has been argued by Soares da Silva et al. (2021. Null se constructions in Brazilian and European Portuguese: Morphosyntactic deletion or emergence of new constructions? Cognitive Linguistics 32(1). 159–193) that differences in conceptualization of an event as “energetic” or “absolute” primarily drive the variation. This article focuses on the (re)configuration of the network of se constructions in light of the overt-null alternation. Given that the alternation is systematic for all types of se construction, we propose that both the marked and unmarked constructions are plotted onto the conceptual map of MV constructions. As to the introduction of the null variant in the taxonomy of se constructions, we argue that the overt-null variants are allostructions posited at lower levels of abstraction. We also hypothesize that the middle marker at the top node is underspecified for function, instantiated as an intransitivizer, or lexically defined at the immediate subordinate level.

Authors: Prasad Arvind , Vijayan Kadukkappilly S. , Rao Ravinuthala V. S. , Narasimhan Desigan , Krishnamoorty Ananthasivan
Published: February 2024

Plutonium oxalate supernatant requires a treatment step for further recovery of the residual Pu. As the oxalate ion present in the solution poses problems during the recovery of Pu, it needs to be destroyed. In the present work, Mn2+ based catalytic destruction of oxalate ion was studied in detail, as it could minimize the generation of secondary radioactive waste compared to the conventional process. The effect of various parameters, namely concentrations of HNO3, catalyst, oxalic acid and effect of the metal ion has been studied. Moreover, the robustness of the catalytic destruction method along with the kinetics of oxalate destruction reaction has been investigated. The process was also demonstrated with Pu supernatant generated from CORAL at 1 L scale.
210Pb dating and neutron activation analysis of the Sundarban mangrove sediments: sedimentation rate and metal contamination history
Authors: Islam Mohammad Amirul , Kabir Shaiful , Lubis Ali Arman , Sugiharto Untung , Islam M. Moinul , Hossen Mohammad Belal
Published: February 2024

In this study, alpha spectrometry and neutron activation analysis were applied to assess the mass accumulation rate, contamination history, and ecological risk of the Sundarban mangrove sediments. The mass accumulation rates of sediments using 210Pb dating determined for the first time in this area ranged from 0.068 to 3.20 kg m−2 y−1, with an average of 0.61 kg m−2 y−1. The contamination history of 11 metal(loid)s (Al, Ca, V, Cr, Fe, Ni, Cu, Zn, As, Hg, and Pb) was assessed. Different environmental contamination indices suggested that Sundarban mangrove sediments were contaminated by As. Considering different sediment quality guidelines, it was observed that Cr, Ni, and As posed occasional adverse biological effects on marine organisms. Multivariate statistical approaches were applied to elucidate the origin and transport behavior of the studied metal(loid)s in the mangrove ecosystem which suggested that sources of metal(loid) pollution were both anthropogenic and geogenic. The results from this study should improve the knowledge of metal contamination and ecological risk to biota to develop new strategies and enlarge management practices to save sensitive mangrove ecosystems.
Imagic iconicity as thematic representation in selected Nigerian children’s poetry
Authors: Nwuche Amaka Grace , Ngonebu Chinyere Loretta , Unachukwu Ogechi Chiamaka
Published: February 2024

Sounds play crucial roles in a poem’s meaning (re)construction. Grasping the content of a literary work such as poetry often requires a profound interpretation of the underlying linguistic cum phonetic codes of its discourse. Extant studies on Nigerian children’s poetry have paid little attention to this aspect of meaning conception, thereby concentrating mainly on the surface lexical constructs. Hence, this study aims to examine imagic iconicity in children’s poems in order to demonstrate how a poem’s thematic realization is inferred through the interpretation of the phonic and acoustic nature of the sounds employed. The study involves five poems: three from Ossie Enekwe’s Gentle Birds Come to me and two from Ikeogu Oke’s Song of Success and Other Poems for Children. The analysis is anchored to insights from Charles Sanders Peirce’s concept of the iconic sign, and exploits the action of acoustic and phonetic articulation of sounds to determine their functions and effects in the poems. The study reveals how specialized lexemic choices and onomatopoeia (kinaesthemes, phonaestheme or sound symbolism) in children’s poems make each poem functional and purposeful. Thus, children’s poetry contains language structures and configurations that transmit sense and embody what the poem is asserting in a way that interestingly engages the reader.
Genre-structural analysis of Arabic accident news reporting
Authors: Alshehri Abdulmohsin A.
Published: February 2024

This paper is concerned with an exploration of the structural arrangement of Arabic hard news reporting with reference to a corpus of twenty accident news stories drawn from two leading Middle Eastern news organizations, Aljazeera and Alarabiya. A range of journalistic traditions has been examined with respect to organizational structures used in their hard news reporting texts. Within journalism discourse analysis, the nucleus-satellite structure developed by scholars of Systemic Functional Linguistics (SFL) is commonly found in news reporting in English and across various languages. However, news media texts in some cultures, such as Arabic, have not undergone any close scrutiny from a generic perspective. Accordingly, this study attempts to fill such a gap by investigating the genre-related features of the Arabic accident reports, drawing on the insights provided by SFL literature on the news story as a genre. It employs various lines of analysis such as textual deconstruction, timeline, radical editability, and lexical chaining. The findings of these analyses suggest that the Arabic accident news reports are non-chronologically organized operating with the lead-dominated orbital model, and thus generically bearing a close resemblance to the English news reports.
Indirect truth marking via backgrounding: evidence from Bantu
Authors: Kerr Elisabeth J. , Van der Wal Jenneke
Published: February 2024

Verum focus has long been analysed as part of information structure, being accounted for within a theory of focus as generation of alternatives on a polarity value. Recently, however, this view has been challenged, with some authors arguing for a separation between verum and focus. The empirical debate focuses on two types of strategies: either verum is marked identically to focus (e.g., pitch accent in German, English) or through a dedicated strategy (e.g., dedicated markers in Gitksan, Bura, South Marghi). On the basis of the second type, it has been argued that the link between focus and verum is only superficial, with verum instead arising from a lexical operator VERUM. In this paper, we provide evidence in support of the traditional link between truth marking and focus, using original field data on the morphosyntactic expression of information structure in 11 Bantu (Niger-Congo) languages. By working from function to form, we show that these languages use a variety of grammatical strategies for truth expression, strategies that are used elsewhere in the information structural system for backgrounding. In this way, verum is not directly marked by focal accent but marked indirectly via backgrounding, which we formulate as theBackgrounding and Underspecification Thesis(BUT). On the basis of this Bantu evidence, we add a third type of strategy to the typology, where verum is marked indirectly via backgrounding. We use this updated typology to argue in favour of maintaining a conceptual link between verum, polarity focus, and predicated-centred focus more broadly.
Vaginal Metastatic Recurrence of a Bladder Tumor after Anterior Pelvectomy – A Case Report
Authors: Aboulaich Youness , Kharbach Youssef , Khallouk Abdelhak
Published: February 2024

Background: Vaginal metastatic recurrence after anterior pelvic pelvectomy for bladder tumor is a rare occurrence that remains unexplained and requires specific recommendations to prevent or effectively treat it in a timely manner.Case report: We report on a 69-year-old female patient with a history of hyperthyroidism who had undergone anterior pelvic pelvectomy for bladder tumor and presented a year later with vaginal bleeding. Gynecological examination with a speculum revealed four small budding tumors on the anterior vaginal wall. An anatomopathological study confirmed urothelial carcinoma. We performed surgical excision of all masses and complemented it with radiotherapy.Conclusion: The purpose of our presentation is to discuss predictive factors for vaginal metastatic recurrence and to emphasize the importance of gynecological examination in follow-up after anterior pelvic pelvectomy, which we believe should be included in the recommendations for such follow-up.
A Case Report on Congenital Biliary Atresia with Ventricular Septal Defect

Published: February 2024

Biliary atresia, an obstructive cholangiopathy with an idiopathic etiology, is a congenital disorder that eventually destroys liver parenchyma. In some circumstances, it is associated with other abnormalities such as congenital heart diseases, intestinal, and spleen anomalies. Diagnosis of biliary atresia is based on clinical manifestations and specific diagnostic tests. Prolonged pathological jaundice is a critically important sign in newborns that needs to be recognized early in order to reduce the chances of further complications. The mainstay of treatment is the Kasai procedure (portoenterostomy), and it is eighty percent successful if performed before or within the first two months of life.Here, we report a case of a two-month-old baby who had biliary atresia with a ventricular septal defect (VSD). The baby had a prolonged history of jaundice, pruritus, yellow-colored urine, and pale stools. He was initially brought to a local clinic for his jaundice, where pharmacological treatment was commenced. However, the symptoms persisted, and he was referred to a hospital where he was placed under blue light phototherapy with no marked improvement in his symptoms. For a definite diagnosis and treatment, he was then referred to a multispecialty hospital where diagnostic tests were ordered. The HIDA scan showed no uptake of contrast in the bile ducts and gallbladder, which is suggestive of congenital biliary atresia. An intraoperative cholangiogram showed a definite diagnosis of biliary atresia, which was performed, and the Kasai procedure was done successfully. All his family members were healthy with no history of congenital disease.The essential outcome in this case is to consider biliary atresia as a cause of prolonged jaundice in infants, and occasionally it is associated with other congenital anomalies. The diagnosis and treatment should be urgent in order to prevent complications.
Prensa y policía. La Jefatura montevideana en las páginas de La Tribuna Popular (1911-1923)
Authors: Fessler Daniel
Published: February 2024

In this article I intend to study the relationship between a sector of the Montevideo Press and the Capital’s Police Headquarters during the 1910s and the early 1920s of the twentieth century, from a quantitative approach, through the analysis of news related to the crime. A moment that stood out because of the tension between newspapers and authorities of the time. For this, I focused on La Tribuna Popular, an organ that closely followed the police chronicles and reports , supporting the idea of the growth in the crime rate in the city. Traditionally , its argument was based on questioning criminal law, the administration of justice and especially the functioning of the Montevideo Police force itself. My proposal aims to analyze the relationship of the evening newspaper with two of the most censored chiefs of the period (Juan Antonio Pintos and Virgilio Sampognaro) until the change of course which was produced by the assumption of Gómez Folle in the year 1923. The present work confirms the impact that the permanent preaching through editorials and articles dedicated to tracking and monitoring criminal information had. That impact eroded the prestige of an institution systematically presented under the qualifier label of madness or insanity.
Assessment of the ability for early detection of newly hatched larvae of Hylotrupes bajulus L. using the acoustic emission method in Scots pine wood
Authors: Krajewski Adam , Bilski Piotr , Witomski Piotr , Bobinski Piotr
Published: February 2024

The acoustic emission analysis method was used to determine the activity of very young Hylotrupes bajulus larvae in their long-term development. In the laboratory conditions the simulated scenario of a fresh, intense infestation inside the construction wood was evaluated. The sounds generated by the insects during their feeding on the wooden samples were processed by the measurement system, which was able to detect and count the larva-originated sound pulses and calculate related energy. So far, no one has examined possibilities of detecting infant larvae of Hylotrupes bajulus L. This work is a continuation of research on the influence of the insect mass on its AE-based detection. The experiments performed with multiple wood samples analyzed through the period of one year have shown dependency between the mass of the larva and the intensity of the sound generated by them. The moment of the earliest possible detection of infestation in the wooden structure was evaluated. In the appropriate conditions (large number of young larvae inside the wood and optimal temperature) the insects reach the mass of tens of mg, which makes them detectable using the AE method.

Published: February 2024

Particulate matter (PM), usually formed as aerosols suspended in atmosphere, is becoming a carrier of viruses and bacteria, accelerating the spread of respiratory diseases. Hence, air filtration devices are widely utilized for removing PM. In this study, a regenerated cellulose (RC) film was prepared with the properties of good mechanical strength, antibacterial, and highly efficient filtration (EF) properties, through cellulose dissolution and further crosslinking with P(AGE-DMDAAC)/ZnO. Results exhibited that the Young’s modulus of the composite membrane was nearly 4.3 GPa. Additionally, the antibacterial performance against Escherichia coli and Staphylococcus aureus, was up to 99.89% and 99.67%, respectively. Meanwhile, RC composite filter exhibited a high PM 2.5 capture efficiency (over 99.91%). This study introduces an interesting approach to produce antibacterial films with the characteristics of notably good mechanical performance and high fine particle EF that can be utilized in a high humidity environment.
The Design and Operation of a Computer-Controlled Flow Box
Authors:   Wiggins Teape Ltd., Dartford Paper Mill, Kent, Wells B. W.
Published: February 2024

One of the problems encountered during the computerisation of No. 6 machine at Dartford was the need for α flow box control system to replace the existing Hornbostel hole arrangement. The circumstances were such that we required α control system implemented by the computer program (DDC) and the facilities for bumpless transfer to an analog controller arrangement in the event of computer failure. To attain reliability and simplicity, we limited our investigations to the manipulation of the stock and air pressure supply valves to effect automatic control. Our control objectives were 1) The minimisation of level and total head variability. 2) The maintenance of stable control at all times. 3) The inclusion of efflux ratio control, in the computer controller, to reduce general variability and aid weight changes.

Control systems, whereby a final customer may obtain a satisfactory product after it has passed through several stages of manufacturing, are characterised by considerable time delays in both feedforward and feedback paths. These systems are examples of the industrial dynamics problems investigated by Forrester and others. The matter under discussion in this paper is concerned with the establishment of sensible control systems and the maintenance of their reliability and accuracy. It specifically considers paper products used in data processing as punched cards and forms for optical character recognition.
Industrial Dynamics: A Technique for Gaining Understanding of Complex Systems
Authors:   IPC (Group Management) Ltd., Feltham, Middx., Anderton R. H.
Published: February 2024

Control of a complex organisation requires that its response to decision inputs be predictable . Traditionally, this has been made possible by almost breaking down the organisation into very simply coupled subsystems. This allows decision-makers to use a relatively simple and usually informal model. Size and environmental rate of change are now tending to make the decoupling hard to make effective. Industrial dynamics provides both a theoretical structure and a computer simulation technique designed to provide decision-makers with a richer model of the dynamic feedback processes generally involved in industrial operations. The structure defines a system in terms of a closed boundary containing feedback loops, which in turn are formed by the relation between level and rate variables. The DYNAMO compiler allows models of systems conceived on these lines to be programmed in a straightforward way so as to allow experimental investigation of the system variables. The paper discusses case studies and concludes with notes on model validity and the problem of data.

Published: February 2024

Paper-like products or paper substitutes made largely from synthetic polymers are classified as synthetic paper, as recently proposed from Japan. (¹) Several different types have been developed and the most important are in the following three groups: 1. Spunbonded sheets. 2. Paper-like polymer films (including foamed sheets). 3. Synthetic pulp products. In addition, there are various combinations of synthetic polymers with pulp fibres that have been developed, tested and used as paper products for example, addition of synthetic fibres to pulp fibres, impregnation of pulp fibres with synthetic polymers, lamination of paper and board with synthetic polymers and graft copolymerisation of synthetic polymers to pulp fibres. Some of these processes and products are well known and conventional (such as lamination) and some are experimental only (such as grafting) they will therefore not be further described here. One type of synthetic pulp called fibrids was developed early as a thermoplastic binder in paper. (²,³) In principle, fibrid technology is related to synthetic pulp production (group 3).
The Behavior of Single Woodpulp Fibres under Tensile Stress
Authors:   Pulp & Paper Research Institute of Canada, Pointe Claire, Page D. H.
Published: February 2024

Dr Page presented an interesting film with an informative commentary upon it, which without the film is not of value in itself and so cannot usefully be reproduced, but the authors have provided the following synopsis. A unique apparatus has been built and techniques developed that permit a fresh approach to the study of fibre properties. The apparatus is a stress/strain recorder for testing single fibres under axial tensile load. It is fitted with a high power polarising scopial image and the trace of the stress/strain curve can be recorded on cine film, in synchronism, so that the visual appearance of the fibre and its state of stress and strain at any time can be displayed. The detailed physical events that coincide with initiation of yield and failure are dramatically revealed. The presentation consisted of a series of cine sequences that demonstrate phenomena that relate to the tensile properties of fibres, including: 1. The effect of fibril angle on fibre strength and stretch-to-break. 2. The initiation of rupture by defects. 3. The tensile behaviour of microcompressed fibres. 4. The phenomena that occur when a fibre dries under tensile stress. 5. The tensile behaviour of wet fibres.
El papel de la universidad en el fomento del espíritu emprendedor: estrategias y buenas prácticas

Published: February 2024

Today, entrepreneurship is crucial for economic growth and innovation. Therefore, we seek to analyze the role of universities in fostering entrepreneurship and to learn about strategies and good practices to promote entrepreneurship among students. To this end, a multimodal systematic review was conducted. The results highlight that integrating entrepreneurship into the curriculum, providing financial support and access to resources, establishing incubators and co-working spaces, networking with industry and local entrepreneurial ecosystems, and offering mentoring and business advice are effective strategies to promote entrepreneurship among university students. In addition, five key elements are identified to create an enabling environment for successful entrepreneurship: fostering an entrepreneurial culture, providing education and training, offering financial support, and establishing partnerships for mentoring and business advice. It recommends allocating resources, implementing mentoring programs, fostering interdisciplinary cooperation, knowledge transfer and collaboration with business and civil society, and continuously evaluating and improving entrepreneurship policies. In short, it offers a comprehensive view of the role of universities in promoting entrepreneurship and provides recommendations for its promotion.

The objective of this paper is to know the perception of customers regarding the marketing mix in the traditional hardware industry in Metropolitan Lima. The marketing mix is a business strategy that has recently undergone a relevant development that has an impact on major challenges in the economy. In this context, the marketing mix is defined in four dimensions: Product, Price, Place and Promotion. The study is of descriptive design, under this methodology was included a survey to collect information from a representative sample of 385 customers of traditional hardware stores. A 15-item Likert scale survey, validated by experts and with high reliability, was used. The results showed that customers consider basic aspects such as product quality and variety, price of hardware stores in the capital is better, distribution channels, logistics and advertising have an important scope and manage to attract customers. Perception levels were between low and fair in most dimensions of the marketing mix. It was shown that there are significant differences in the average perception of the marketing mix dimensions in at least two age groups and in the customers' area of residence. In conclusion, customers have a positive perception of marketing mix strategies and their impact on business results, which is reflected in better sales and therefore higher revenues.
Una asociación indispensable: liderazgo gerencial y resultados de gestión en el Sector Educación de la Autoridad de Reconstrucción con Cambios
Authors: Delgado Vera Gloria María
Published: February 2024

Asumir que el liderazgo es efectivo cuando se logran los resultados planificados, esto es lo esperado en el orbe empresarial. Por supuesto, no todos los escenarios son iguales. En situaciones más complejas, como la pandemia del COVID-19, los buenos resultados son más sobresalientes, a tal nivel que es pertinente reflexionar académicamente la asociación entre la acción y el logro.  Por ello, el presente artículo investiga esta problemática para el caso de la Dirección de Intervenciones del Sector Educación (DISE) de la Autoridad para la Reconstrucción con Cambios (ARCC). El objetivo es estimar la relación entre el liderazgo gerencial y los resultados de gestión. El diseño de la investigación fue cuantitativa, correlacional y no experimental, lo que facultó aplicar un cuestionario, previamente validado (Alfa de Cronbach = 0.924), y compararlo con los informes oficiales del resultado de la gestión del 2021 (indicadores ponderados en una escala de 5). Se concluyó, a través del Coeficiente de Correlación Rho Spearman = 0.897 (89.7%) con un p-valor=0 < 0.05, que existe relación directa muy significativa entre el liderazgo gerencial y los resultados de gestión. No obstante, para generalizar el caso como una medida aplicable a instituciones públicas pares, se requiere estudiar las variables con un tipo de metodología mixta.

Authors: Schmidt Urdanivia Johannes , Velásquez Diaz Cecilia del Carmen
Published: February 2024

The main objective of this research was to determine the influence of the 7 Ps of marketing in the commercial performance of public agro-industrial CITEs in Peru. However, the non-implementation of the 7 Ps of marketing by the Centers of Productive Innovation and Technology Transfer (CITE by their Spanish initials) negatively affects their commercial performance. To help improve this problem situation, an experimental study was conducted, where the 7 Ps of marketing were devised and implemented for two agro-industrial CITEs from Peru: CITE Huallaga UT Ambo and CITE Agroindustrial UT Huaura. To achieve an effective design of the 7 Ps of marketing, the results of a situational analysis of these CITEs was considered, as well as the needs and wants of their target audience. After conducting this research, it was concluded that the CITEs which implemented the 7 Ps of marketing had a better performance in the placement of technological services and an increase in the number of agro-industrial companies served, compared to previous years and to other agro-industrial CITEs which did not implement the 7 Ps of marketing.
Pobreza en el Perú: enfoques actuales e impactos de la gestión pública
Authors: Alarcón Huamaní José David
Published: February 2024

El presente artículo tiene por objetivo presentar, en principio, una reseña histórica de los principales enfoques que han tratado la pobreza en sus diversas manifestaciones, para luego  analizar el caso peruano en cuanto a la relación o asociación existente entre la pobreza monetaria y aquella que puede ser medida a través del enfoque de Necesidades Básicas Insatisfechas, y la inversión pública medida a través de la variable formación bruta de capital público, usando como herramienta central el coeficiente de correlación, estableciendo que existe un fuerte grado de asociación, inversa entre la ejecución del gasto público duradero y la reducción de la pobreza, con resultados muy cercanos a la unidad. La principal lección que se puede extraer es que es necesario sostener la aplicación de políticas públicas enfocadas en diversos sectores que provean los mejores resultados en cuanto a la reducción de los ratios de pobreza.

Published: February 2024

El Perú no es ajeno a la evasión tributaria. En el 2021 la evasión y elusión alcanzaron el 8% del Producto Bruto Interno (PBI), magnitud equivalente a casi dos veces el monto presupuestal asignado al sector educación. Por ello, la presente investigación tuvo como objetivo determinar la incidencia en la recaudación de impuestos producida por la facturación electrónica del sector construcción en el Perú. El método utilizado fue de índole cuantitativa y el diseño fue no experimental de serie de tiempo, usando la técnica de recopilación de datos estadísticos y bibliográficos. Esta investigación se llevó a cabo con el uso de herramientas matemáticas y estadísticas del programa SPSS, obteniendo como resultado que el uso de la facturación electrónica tuvo incidencia positiva en la recaudación de impuestos en el Perú entre los años 2010 al 2021, constituyendo un mecanismo de lucha contra la evasión de impuestos en el sector construcción. Para la prueba de hipótesis normalidad de Shapiro-Wilk se usó la prueba estadística rho de Pearson, la misma que muestra un coeficiente P value = 0.002 que, al ser menor al 0.05, define un alto nivel de significancia entre las variables correlacionadas. Se concluye que la incidencia de la facturación electrónica es sensiblemente significativa en la recaudación de impuestos del sector construcción en el Perú; así pues, la incidencia podría incrementarse porque la obligatoriedad de la facturación electrónica se dio en todas las empresas del sector recién a partir de junio del 2022.
Gobiernos subnacionales, recursos naturales y pobreza en el Perú: La asignación de recursos del Canon 2001-2022
Authors: Cornejo Ramirez Enrique Javier
Published: February 2024

Este artículo tiene como objetivo analizar la calidad de la gestión pública de los gobiernos subnacionales (municipios provinciales y distritales) en el Perú en las dos últimas décadas, específicamente de aquellos que tienen recursos naturales (mineros, petroleros, gasíferos) que se explotan, por lo que reciben importantes recursos tributarios vía canon, sobre canon y regalías, enfatizando en la ejecución presupuestal de inversiones, los proyectos priorizados y el impacto que estos vienen teniendo en la mejora de los niveles de vida y disminución de la pobreza en dichas zonas del interior del país. Se concluye que ha habido avances, pero se evidencia falta de planeamiento estratégico, inadecuada priorización de las inversiones, deficiencia en la gestión pública, bajos niveles de calificación del personal a cargo y el mantenimiento de brechas sociales que deberían haberse atenuado sustantivamente.

Digging up Old Stories: How the Soviet Myths of Allied Intervention into the Russian North in 1918–1919 are used in the Context of Russia’s War in Ukraine. The Case of Mudyug Concentration Camp Museum
Authors: Golysheva Natalia
Published: February 2024

The mythology of the foreign interference into the Russian civil war goes to the heart of the memory politics in Putin’s Russia today, most recently in connection with the invasion in Ukraine. In a bid to unite the country against perceived threats from the NATO alliance, the Russian leadership engages Soviet narratives going back to the Allied intervention into North Russia in 1918–1920, as a deterrent against association with the West. During Soviet times multiple memorials were created in the North to the victims of intervention in support of this narrative. Central to it was the Mudyug ‘concentration camp’ museum, established to demonstrate the atrocities of the intervention forces. Following the collapse of the Soviet Union this museum was branded as propaganda and eventually got decommissioned. Yet after Russia’s annexation of Crimea in 2014 and subsequent war with Ukraine, the old intervention narratives saw a comeback. Backed by the state, the local memory activists in Arkhangelsk in North Russia took to restoring the Mudyug camp museum as a forepost of patriotic tourism in the region.
