Benefits, Entitlements and Non‐Responsible Threats
Authors: Slavny Adam
Published: June 2018

This article offers an explanation for the proposed moral asymmetry between non‐responsible threats and innocent bystanders. Some argue that a non‐responsible threat – a person who threatens another through no fault or choice – is required to bear a greater burden to avert the threat than a bystander. I argue that previous attempts to explain this asymmetry are either incorrect or incomplete, since they either implausibly suggest that agents who do not benefit from their bodily resources, or whose bodily resources primarily benefit third parties, are liable to greater costs than a bystander, or fail to accommodate such cases. Instead, the asymmetry (when it exists) is explained either by virtue of the fact that the non‐responsible threat has a beneficiary status with respect to the threatening object, or possesses distribution‐limiting entitlements over the threatening object.

Published: June 2018

Background

The number of elderly patients with psoriasis is steadily increasing in the Western world; nevertheless, they are frequently excluded from biological clinical trials and described as a high‐risk group for adverse events. Thus, there is lack of information concerning safety and effectiveness of available treatments for psoriasis in the elderly, particularly about new biological systemic drugs.

Objective

Our aim was to describe our experience with all biological therapies currently used in the elderly (>65 years) psoriatic patients.

Methods

A retrospective multicentric review of clinical records of all psoriatic patient aged 65 years or older actually receiving biological drugs (etanercept, adalimumab, infliximab, golimumab, certolizumab pegol, ustekinumab or secukinumab) was undertaken.

Results

Our study population included 266 elderly psoriatic patients actually receiving any biological therapy (adalimumab 31.2%, ustekinumab 28.9%, etanercept 20.3%, secukinumab 15%, infliximab 3%, golimumab 1% and certolizumab pegol 0.6%). The PASI score at the baseline (week 0) ranged from 4 to 54; mean ± SD, 16.5 ± 7.1, which changed after biological administration to 3.7 ± 8 at week 16, 1.6 ± 2.1 at week 28 and 1.2 ± 2.1 at week 52. Among 266 elderly psoriatic patients, 25 adverse events were reported during the observation period. The most frequent events were infections with 12 (48%) reports, followed by malignancies with four (16%) reports.

Conclusions

To date, our study represents the widest experience on the use of biological drugs in elderly psoriatic patients. We found that all biologics for psoriasis showed a great efficacy also in elderly people, and the rate and the type of adverse effects were similar to the younger patients. In conclusion, the age alone should not limit our therapeutic options. Further observational study using multiple data sources is needed to evaluate long‐term effectiveness and safety for elderly psoriatic patients.
Interactions of Gender and Number Agreement: Evidence from Bosnian/Croatian/Serbian
Authors: Puškar Zorica
Published: June 2018

Split hybrid nounsin Bosnian/Croatian/Serbian display two sets of interesting properties: they can bear both natural and grammatical gender, and which gender participates in agreement depends on the number of the noun. While in the singular they invariably trigger natural‐gender (masculine) agreement, optionality between natural‐ and grammatical‐gender (feminine) agreement obtains in the plural. Such nouns pose two theoretical challenges: (i) Agree must be able to operate on two kinds of gender, and (ii) gender must be allowed to interact with number. Previous accounts propose complex mapping between semantic, syntactic, and class features but ultimately cannot derive the obligatoriness of natural‐gender agreement in the singular and natural–grammatical optionality in the plural in a unified way. I provide a Minimalist analysis of hybrid nouns’ agreement, combining the formal tools of feature hierarchies and relativized probing, which derive the obligatoriness of natural gender in the singular, with Cyclic Agree with different orders of Agree operations, which derives the natural–grammatical optionality as intervention effects.

Accuracy of glycosuria, random blood glucose and risk factors as selective screening tools for gestational diabetes mellitus in comparison with universal diagnosing
Authors: Agbozo Faith , Abubakari Abdulai , Narh Clement , Jahn Albrecht
Published: June 2018

Objective

Despite the short-term and long-term health implications of gestational diabetes mellitus (GDM), opinions are divided on selective vis-à-vis universal screening. We validated the accuracy of screening tests for GDM.

Research design and methods

Pregnant women (n=491) were recruited to this prospective, blind comparison with a gold standard study. We did selective screening between 13 and 20 weeks using reagent-strip glycosuria, random capillary blood glucose (RBG) and the presence of ≥1 risk factor(s). Between 20 and 34 weeks, we did universal screening following the ‘one-step’ approach using glycated hemoglobin (HbA1c), fasting venous plasma glucose (FPG), and the 1-hour and the ‘gold standard’ 2-hour oral glucose tolerance test (OGTT). Tests accuracy was estimated following the WHO and the National Institute for Health and Care Excellence (NICE) diagnostic criteria. Overall test performance was determined from the area under the receiver operating characteristic curve (AUC).

Results

GDM prevalence per 2-hour OGTT was 9.0% for the WHO criteria and 14.3% for the NICE criteria. Selective screening using glycosuria, RBG and risk factors missed 97.4%, 87.2% and 45.7% of cases, respectively. FPG threshold ≥5.1 mmol/L had the highest clinically relevant sensitivity (68%) and specificity (81%), but FPG threshold ≥5.6 mmol/L had higher positive predictive value. Although sensitivity of 1-hour OGTT was 39.5%, it had the highest accuracy and diagnostic OR. Regarding test performance, 1-hour OGTT and FPG were very good (AUC>0.8), RBG was poor (AUC≈0.60), whereas HbA1c was invaluable (AUC<0.5).

Conclusions

Selective screening using glycosuria and random blood glucose is unnecessary due to its low sensitivity. Fasting glucose ≥5.1 mmol/L could be applicable for screening at the population level. Where 2-hour OGTT is not available, FPG ≥5.6 mmol/L, complemented by the presence of risk factors, could be useful in making therapeutic decision.
Feature-Driven Mediator Synthesis

Published: June 2018

As the number, complexity, and heterogeneity of connected devices in the Internet of Things (IoT) increase, so does our need to secure these devices, the environment in which they operate, and the assets they manage or control. Collaborative security exploits the capabilities of these connected devices and opportunistically composes them to protect assets from potential harm. By dynamically composing these capabilities, collaborative security implements the security controls that satisfy both security and non-security requirements. However, this dynamic composition is often hampered by the heterogeneity of the devices available in the environment and the diversity of their behaviours. In this article, we present a systematic, tool-supported approach for collaborative security where the analysis of requirements drives the opportunistic composition of capabilities to realise the appropriate security control in the operating environment. This opportunistic composition is supported through a combination of feature modelling and mediator synthesis. We use features and transition systems to represent and reason about capabilities and requirements. We formulate the selection of the optimal set of features to implement adequate security control as a multi-objective constrained optimisation problem and use constraint programming to solve it efficiently. The selected features are then used to scope the behaviours of the capabilities and thereby restrict the state space for synthesising the appropriate mediator. The synthesised mediator coordinates the behaviours of the capabilities to satisfy the behaviour specified by the security control. Our approach ensures that the implemented security controls are the optimal ones, given the capabilities available in the operating environment. We demonstrate the validity of our approach by implementing a feature-driven mediation for collaborative security tool and applying it to a collaborative robots case study.
CHARIOT

Published: June 2018

An emerging trend in Internet of Things (IoT) applications is to move the computation (cyber) closer to the source of the data (physical). This paradigm is often referred to as
edge computing
. If edge resources are pooled together, they can be used as decentralized shared resources for IoT applications, providing increased capacity to scale up computations and minimize end-to-end latency. Managing applications on these edge resources is hard, however, due to their remote, distributed, and (possibly) dynamic nature, which necessitates autonomous management mechanisms that facilitate application deployment, failure avoidance, failure management, and incremental updates. To address these needs, we present CHARIOT, which is orchestration middleware capable of autonomously managing IoT systems consisting of edge resources and applications.

CHARIOT implements a three-layer architecture. The topmost layer comprises a system description language, the middle layer comprises a persistent data storage layer and the corresponding schema to store system information, and the bottom layer comprises a management engine that uses information stored persistently to formulate constraints that encode system properties and requirements, thereby enabling the use of satisfiability modulo theory solvers to compute optimal system (re)configurations dynamically at runtime. This article describes the structure and functionality of CHARIOT and evaluates its efficacy as the basis for a smart parking system case study that uses sensors to manage parking spaces.
A Survey of Mobile Crowdsensing Techniques
Authors: Liu Jinwei , Shen Haiying , Narman Husnu S. , Chung Wingyan , Lin Zongfang
Published: June 2018

Mobile crowdsensing serves as a critical building block for emerging Internet of Things (IoT) applications. However, the sensing devices continuously generate a large amount of data, which consumes much resources (e.g., bandwidth, energy, and storage) and may sacrifice the Quality-of-Service (QoS) of applications. Prior work has demonstrated that there is significant redundancy in the content of the sensed data. By judiciously reducing redundant data, data size and load can be significantly reduced, thereby reducing resource cost and facilitating the timely delivery of unique, probably critical information and enhancing QoS. This article presents a survey of existing works on mobile crowdsensing strategies with an emphasis on reducing resource cost and achieving high QoS. We start by introducing the motivation for this survey and present the necessary background of crowdsensing and IoT. We then present various mobile crowdsensing strategies and discuss their strengths and limitations. Finally, we discuss future research directions for mobile crowdsensing for IoT. The survey addresses a broad range of techniques, methods, models, systems, and applications related to mobile crowdsensing and IoT. Our goal is not only to analyze and compare the strategies proposed in prior works, but also to discuss their applicability toward the IoT and provide guidance on future research directions for mobile crowdsensing.
The Lessons and Limitations of Experiments in Democratic Deliberation
Authors: Gastil John
Published: June 2018

Experiments are essential to the practice of democratic deliberation, which itself is an experimental remedy to the problem of self-governance. This field, however, is constrained by the impossibility of conducting ecologically valid experiments that take into account the full complexity of deliberative theory, which spans different levels of analysis and has a multidimensional variable at its core. Nonetheless, informative patterns have emerged from the dozens of lab studies, survey experiments, and quasi-experiments in the field conducted to date. This body of work shows the feasibility of gathering diverse samples of people to deliberate, but it also underscores the difficulties that arise in deliberation, including extreme disagreement, poor conflict management, and how a lack of diversity can forestall meaningful disagreement. When public engagement strategies and discussion formats mitigate those hazards, deliberation can improve participants’ understanding of issues, sharpen their judgments, and change their attitudes toward civic engagement. Well-publicized deliberative minipublics can even influence wider public opinion and voting intentions.

Institutional Specialization and Survival: Theory and Evidence from the French Film Industry
Authors: Jourdan Julien
Published: June 2018

Firms increasingly face fragmented institutional environments where stakeholders endorse different institutional logics. Although the effects of market specialization have been extensively studied, we do not know much about the firm-level implications of institutional specialization, i.e., when firms demonstrate consistent conformity to an institutional logic. In this study, I explore whether and to what extent institutional specialization affects firm survival. In contrast with arguments and evidence highlighting the potential negative survival effect of market specialization, I posit that institutional specialization is positively associated with survival. Because they may be more skilled at interacting with stakeholders, which perceive them as more appealing and understandable, institutional specialists, I argue, are more likely than other firms to form and maintain the reciprocal stakeholder relationships needed to operate and survive. I expect the survival benefit of institutional specialization to be accentuated when the contrast between logics decreases. I test and find support for these ideas using unique population data on French film producers (1994–2008).

Linearity in decimation-based generators: an improved cryptanalysis on the shrinking generator
Authors: Cardell Sara D. , Fúster-Sabater Amparo , Ranea Adrián H.
Published: June 2018

Decimation-based sequence generators are a class of non-linear cryptographic generators designed to be used in hardware implementations. An inherent characteristic of such generators is that their output sequences are interleaved sequences. This profitable characteristic can be used in the cryptanalysis of those generators. In this work, emphasis is on the most representative decimation-based generator, the shrinking generator, which has been cryptanalyzed just by solving linear equation systems. Compared with previous cryptanalysis, computational complexity and intercepted sequence requirements are dramatically reduced. Although irregularly decimated generators have been conceived and designed as non-linear sequence generators, in practice they can be easily analyzed in terms of simple linear structures.
Precise Measurement of Steep Residual Strain Gradients Using Neutron Diffraction in Strongly Absorbing Materials with Chemical Compositional Gradients
Authors: Wimpory Robert C. , Hofmann Michael , Akrivos Vasileios , Smith Mike C. , Pirling Thilo , Ohms Carsten
Published: June 2018

A round robin benchmark weldment, denoted TG6, from the European Network on Neutron Techniques Standardization for Structural Integrity (NeT), offers the ability to test the technique of residual stress determination using neutron diffraction to an extreme. This test component comprises a 200 mm by 150 mm by 12 mm rectangular base plate made from Inconel 600 with three passes of Alloy 82 weld metal deposited in a slot of length 76 mm. This not only has large grain issues in the weld region but a large interplanar spacing variation caused by high strain gradients and a change in material composition. Because of the high absorption of neutrons in the Inconel 600 within the gauge volume, there is a large difference between the instrumental gauge volume IGV (which is the volume of space defined by the neutron beam paths through the defining apertures, taking into account properties of the beam) compared with the sampled gauge volume SGV (which is the intersection of the IGV with the sample that takes into account the absorption of the neutrons). The relative shift in position of the center of gravity of measurement (when the gauge volume is fully immersed in the sample) has been observed to be significant, for example, ∼0.3 mm, using 1 by 1 by 5 mm3 defining optics (where 5 mm is the gauge volume height) and increases approximately proportionally with larger gauge volumes dimensions in the horizontal plane. The magnitude of this shift depends upon many parameters. Measuring the sample and rotating 180° and measuring again, taking the average is another way one can eliminate this absorption effect. This novel approach is compared with three neutrons instruments on the same sample.

El artículo analiza el significado histórico y literario de los cuadros de costumbres del guatemalteco José Milla, en cuanto portadores de un proyecto político e ideológico en torno a la idea de nación. Agrupado el corpus en dos categorías (los que exponen los estereotipos masculinos y los que se ocupan de los femeninos), se describe como aspecto esencial un proyecto, desde el discurso literario, de homogenización de la sociedad guatemalteca. Entre otros aspectos, se destaca el binomio civilización/barbarie y otras oposiciones relacionadas. Se está ante la construcción de una idealización utópica de la sociedad guatemalteca a lo largo del siglo XIX. AbstractThe article analyzes the historical and literary meaning of the prose sketches on customs by the Guatemalan José Milla, written to portray a political and ideological proposal developed around the concept of nation. The corpus is divided into two categories of stereotypes (masculine and feminine). That project, concerning the homogenization of the Guatemalan society, is described through literary discourse, as an essential element. Emphasis is given to aspects such as the binomial civilization/barbarism and other related oppositions. This conveys the construction of the utopic idealization of Guatemalan society throughout the 19th century.
Modelling node-selection behaviour in subway stations
Authors: Chen Xu , Li Haiying , Wang Yutian , Zheng Xun , Miao Jianrui
Published: June 2018

Node-selection behaviour in subway stations directly impacts the utilisation and capacity of equipment and facilities. Although this topic has been extensively studied in various fields, existing studies are limited to environment characteristics while little research has been undertaken from the perspectives of pedestrian and interaction characteristics. In this study, pedestrian node-selection behaviour at automatic fare gates (AFGs) in subway stations was investigated and a multi-nomial logit model was developed that incorporates environment, pedestrian and interaction characteristics. For model estimation and validation, a detailed site survey was carried out to collect data on pedestrians’ actual AFG selection at three Beijing subway stations. The prediction accuracy of the model reached 90·90%. Application of the model is demonstrated by detailed analyses of influence factors from four aspects along with the utilisation optimisation of AFGs in Beijing West subway station.
MANIPULATIVE TECHNIQUES IN UKRAINIAN RELIGIOUS MEDIA DISCOURSE
Authors: LEVKO OLEXANDR
Published: June 2018

The article analyses communicative strategies in the Ukrainian interconfessional media discourse with the particular focus on investigation of the manipulative techniques, based on publications of the religious internet portals "Religijno-informatsijna sluzhba Ukrajiny", "Katolytskyj ogljadach" and "Religija v Ukrajini". It is established that the texts dealing with interconfessional questions resort to manipulative techniques with the purpose of making the audience take a particular viewpoint to important issues in the field of interconfessional relations, as well as with the purpose of presenting the self in favorable light and discrediting ideological opponents. It is also revealed that the most common manipulative techniques, used in the Ukrainian interconfessional media discourse, are name-calling, misuse of concepts, appealing to ideological mythologems, black-white depiction and the use of emotional appeals. It is demonstrated that the ideological mythologems "Russian world", ''Post-Christian Europe", ''Saint Rus", "Godless West", "holy war", "defense of Christians" are used with negative connotations in the Ukrainian interconfessional media texts as means of communicative strategy of opponents’ discrediting.

The study period was from July 2017 to December 2017. All the patients admitted in medical ward with diabetes were studied.Results: A total of 65 patients were included in this study. Majority of patients had diabetes of less than 10 year duration. Around 27.7% who were admitted had some history of foot complaints. However, foot examination was done by physicians only in 7.7% of the cases. It was seen that only 6.2% of the feet were inspected (look component), 1.5% of patients pulses were assessed (Feel component) and none of the patients had their sensation checked (Test component). Ophthalmologist was most commonly consulted specialist (35.4%) for eye evaluation in comparison to surgeon for foot evaluation.Conclusions: Diabetic foot is a common complication of diabetes mellitus and screening of foot is essential to prevent complications and amputation. This study done through Amit Jain’s triple assessment for foot in diabetes showed that foot evaluation was poorly done by physicians.
Assessing the Impact of Reference Assistance and Library Instruction on Retention and Grades Using Student Tracking Technology
Authors: Krieb Dennis
Published: June 2018

Abstract

Objective – To assess the impact of community college academic librarians upon student retention and grades through reference desk visits and attendance in library instruction classes.

Methods – Student ID data used for this research was collected from students that visited the reference desk to consult about a course-related question or attended a library instruction class for a specific course. After consenting to share their student ID number, the students’ IDs were scanned and uploaded to a Blackboard Analytics data warehouse. A Pyramid Analytics reporting tool was used to query and extract student-level retention and grade data based upon whether the student had visited the reference desk or attended a library instruction class. Chi-square and Fisher’s exact tests were used to discern any statistical difference in retention rates and grades between students that engaged a librarian through reference or instruction and the general student population.

Results – When comparing fall-to-fall retention for all degree-seeking students, students that visited the reference desk or attended a library instruction class had a statistically higher rate of retention. When comparing fall-to-fall retention within low-retention student cohorts, students that visited the reference desk or attended a library instruction class had higher rates of retention among all low-retention cohorts. Eight of 10 cohorts were statistically higher for library instruction and 6 of 10 cohorts were statistically higher for reference visits. With respect to course grades, only 1 of 5 high enrollment courses showed a higher grade average for students that attended a library instruction class. None of the differences in average grades between students that attended a library instruction class and all students in the five courses were statistically significant. For the impact of a reference visit upon a course grade, all five courses showed a higher average grade average for students that visited the reference desk for a question related to their course than all students in the course. Four of the 5 differences were statistically significant.

Conclusions – The data collected by systematically tracking students that interact with community college librarians suggests that reference desk visits and attendance of library instruction classes both have a positive, statistically significant impact upon student retention. When looking at course grades, the data does not indicate a statistically significant positive or negative impact for library instruction. The impact of visiting the reference desk upon course grades does suggest a strong, statistically significant positive correlation.

As alterações no uso e ocupação do solo, como impermeabilização, construção de edifícios e supressão vegetal causam alterações nos processos termodinâmicos que envolvem a superfície e a baixa atmosfera. Após discutir conceitos e teorias relacionados ao clima urbano, este artigo avalia os impactos da urbanização sobre parâmetros climáticos como a temperatura do bulbo seco, temperatura do bulbo úmido, umidade relativa do ar e nebulosidade. Para avaliar isso, utilizou-se um teste estatístico de médias com dados obtidos em duas estações meteorológicas – uma localizada na área urbana de Belo Horizonte, e outra localizada poucos quilômetros distantes dessa, na área rural de Ibirité. Os resultados mostram que as alterações antrópicas sofridas pelo ambiente em Belo Horizonte – devido à urbanização –, podem fazer com que as médias dos parâmetros tratados fossem estatisticamente diferentes das médias em Ibirité, confirmando as teorias acerca do clima urbano.

 

ABSTRACT

Changes in land use and occupation such as waterproofing, building construction and vegetal suppression cause changes in thermodynamic processes involving the surface and the lower atmosphere. After discussing concepts and theories related to urban climate, this paper evaluates the urbanization impact on climatic parameters such as dry-bulb temperature, wet-bulb temperature, relative humility and cloud cover. To evaluate this, we used a statistical mean test with data obtained from two weather stations – one located in Belo Horizonte’s urban area, and another located a few miles away from the first, located in Ibirité’s rural area. The results show that anthropic shifts suffered by Belo Horizonte’s environment – due to urbanization – may make its parameters’ means statistically different then Ibirité’s ones, confirming the theories about urban climate.

Effects of drinking water defluoridation with alum (1.5 g/liter) and lime (200 mg/liter) were assessed on mineral, biochemical status and health of fluorotic buffaloes in fluoride endemic South-West Punjab, India. The fluorotic buffaloes (n=16; plasma fluoride: 0.44-0.97 ppm, urinary fluoride: 18.90-39.30 ppm) were randomly divided into two equal groups (Treatment: TRT; Control: CRL). The TRT was offered defluoridated water while CRL was offered non-treated water, adlib for drinking for 135 days. Other feeding and management practices were similar for both the groups. Plasma and urine samples were collected on day 0, 45, 90 and 135 and health of the buffaloes were monitored. The drinking water defluoridation resulted in significant (p Lass Than 0.01) decline in water fluoride contents from 10.64±0.09 to 1.24±0.03 ppm. There was significant (p Lass Than 0.01) decline in plasma and urinary fluoride concentrations and significant (p Lass Than 0.01) increase in plasma calcium, copper and zinc concentrations in the TRT group. There was no effect of water defluoridation on plasma inorganic phosphorus, magnesium, Hb and TEC, however PCV increased and alkaline phosphatase activity decreased significantly (p Lass Than 0.01) in TRT group. Two buffaloes from CRL showed stiffness on day 64 and 81, respectively, while all the buffaloes from the TRT group remained healthy during the study period. It is concluded that defluoridation of drinking water with alum and lime was effective in reducing water fluoride contents to permissible levels and it improved mineral, biochemical status and health of fluorotic buffaloes.

El establecimiento de las competencias sello institucionales misionales en los documentos oficiales de las universidades es de reciente data por lo que, en gran medida, se carece de información suficiente sobre la materia. La presente investigación tiene como objetivo principal abordar, en parte, ese vacío existente. El propósito es determinar a través de qué actividades educativas los docentes de Pedagogía Básica de la Universidad de Playa Ancha promueven y evalúan el logro de estas competencias y cómo se corresponden con las recomendadas por la literatura. Los participantes fueron docentes que imparten clases en la carrera e institución antes mencionadas. A través de la entrevista se pudo constatar que los docentes, mayoritariamente, declaran no realizar, de forma consciente, actividades educativas o estrategias de evaluación que promuevan, por separado y en específico, estas competencias. Aquellos docentes que manifiestan promoverlas lo hacen a través de actividades tales como trabajo colaborativo, lecturas y análisis de documentos, investigaciones empíricas y proyectos educativos. Las estrategias de evaluación empleadas son las siguientes: pautas de desempeño grupal e individual, informes escritos, pruebas individuales de preguntas de desarrollo y pautas de autoevaluación de competencias. Pudo concluirse entonces que los docentes no promueven en forma intencionada y deliberada actividades y estrategias de evaluación auténticas tendientes al desarrollo de competencias institucionales sello misionales lo que, en gran medida, puede impactar negativamente en el logro, por parte de los estudiantes, de competencias tales como la responsabilidad social, el liderazgo y aspectos éticos, entre otras, declaradas en los objetivos de los programas de estudios y perfil de egreso. La variedad y autenticidad de las actividades y estrategias de evaluación usadas no se corresponden con las requeridas. La responsabilidad del docente no excluye, de manera alguna, la obligación de la universidad en cuanto a labores de acompañamiento, capacitación específica, gestión y evaluación para la promoción de competencias sello misionales.
El significado semántico de la investigación científica en los institutos de educación superior tecnológica de Veracruz, México
Authors: Villarruel Fuentes Manuel
Published: June 2018

Actualmente la ciencia, en su calidad de pensamiento dominante, ha impactado de manera decidida en los modelos y enfoques educativos en el nivel superior. Esto ha condicionado el desarrollo de propuestas curriculares y didácticas, que en mayor o menor medida han sido puestas en marcha en los distintos niveles educativos de México, sin que a la fecha exista evidencia del logro efectivo de sus propósitos y metas. Tal es el caso del nivel superior tecnológico (Tecnológico Nacional de México) que desde 2012 ha desplegado un modelo educativo integral en todas sus instituciones. Bajo este contexto se hace necesario un acercamiento que, desde distintos ángulos, explore el fenómeno educativo asociado a la formación científica del estudiante así como la valoración que este hace de su papel en dicho proceso y de la investigación que se realiza dentro de sus planteles. Con base en ello se realizó un estudio bajo la técnica del Diferencial Semántico con el fin de identificar las percepciones que los estudiantes tienen sobre estos aspectos de su alfabetización científica. El estudio consideró un total de 835 estudiantes registrados (regulares) provenientes de 9 planteles (33% del total), inscritos dentro del estado de Veracruz, México. Los resultados mostraron que los estudiantes tienen una imagen poco positiva de sí mismos y de sus compañeros, así como de la educación científica que están recibiendo al igual que sobre la investigación que se realiza dentro de los planteles.
