Relationships between core self-evaluation, leader empowering behavior, and job security among Jordan University Hospital nurses

2021

Nurses are facing real stressors due to patients’ needs and leaders’ demands. The aim of this study is to explore the perceived level of core self-evaluation (CSE), leader empowering behavior (LEB), and job security among Jordan University Hospital nurses in Amman, the capital of Jordan. Furthermore, it investigates the relationship between the selected variables. Differences of gender, educational level, experience, and site of work are also examined with job security. Moreover, it evaluates the contribution of CSE, LEB, gender, educational level, experience, and site of work in predicting job security among Jordan University Hospital nurses. A descriptive cross-sectional design was adopte…

Action Recognition based on Hierarchical Self-Organizing Maps

2014

We propose a hierarchical neural architecture able to recognise observed human actions. Each layer in the architecture represents increasingly complex human activity features. The first layer consists of a SOM which performs dimensionality reduction and clustering of the feature space. It represents the dynamics of the stream of posture frames in action sequences as activity trajectories over time. The second layer in the hierarchy consists of another SOM which clusters the activity trajectories of the first-layer SOM and thus it learns to represent action prototypes independent of how long the activity trajectories last. The third layer of the hierarchy consists of a neural network that le…

Fostering Teacher-Student Interaction and Learner Autonomy by the I-TUTOR Maps

2014

The paper analyses the use of an automatically generated map as a mediator; that map visually represents the study domain of a university course and fosters the co-activity between teachers and stu- dents. In our approach the role of the teacher is meant as a media- tor between the student and knowledge. The mediation (and not the transmission) highlights a process in which theres no deterministic rela- tion between teaching and learning. Learning is affected by the students previous experiences, their own modalities of acquisition and by the in- puts coming from the environment. The learning path develops when the teachers and the students visions approach and, partly, overlap. In this cas…

Semantic sense extraction from Wikipedia pages

2010

This paper presents a technique aimed to extract structured information from unstructured Wikipedia contents related to a particular topic, and to arrange it in a semantic way inside an ontology. The general framework is the design of an artificial agent able to deliberate when increasing its domain knowledge. In particular, this cognitive agent acts as a dialogue manager in an Intelligent Tutoring System (ITS) already presented by the authors. Our approach is based on the definition of useful patterns able to extract and identify novel concepts and relations to be added to the knowledge base. We propose a method that uses information from the wiki page’s structure. We define different stra…

Ikea e altre semiosfere. Laboratorio di sociosemiotica

2019

Da quando l’uomo è diventato sapiens sapiens, la vita non ha a che fare solo con la biosfera ma anche con la semiosfera. Con questo termine ci riferiamo ancora a un insieme di elementi eterogenei che hanno la capacità di produrne altri, solo che tali elementi non hanno una natura chimica o biologica, hanno invece a che fare con le straordinarie capacità mentali che l’uomo possiede. Possiamo allora immaginarci questo spazio popolato da prodotti culturali di varia natura: parole, immagini, discorsi, ma anche oggetti, edifici, abiti, cibo, dove a rendere tali elementi parte del sistema non è unicamente la loro natura materiale, peraltro molto diversa, ma la cosa che di volta in volta li accomu…

La gestione della crisi coniugale attraverso il procedimento collaborativo. Uno studio comparatistico

2016

Family law disputes involve a wide range of emotions affecting the couples and, in particular, their children. The adversary system is not often adequate to manage the resolution of the conflicts between husband and wife, because it stresses the hostility and prevents a normal dialogue, that would be very useful for a peaceful relationship after the divorce. The collaborative method, by contrast, is a settlement-oriented process where parties cooperate fairly in negotiations, assisted by their lawyers, and attempt to solve the family disputes with an equitable agreement. The collaborative law process has two main features: first of all, the lawyers who have assisted their clients in negotia…

Generación de fractales a partir del método de Newton

2013

[EN] A large number of fractals known, as Julia fractals and Mandelbrot, can be generated from an iterative method. In this paper we present a virtual laboratory developed as a Graphical User Interface (GUI) of Matlab that allows us to study and visualize in real time the relationship between Newton iterative methods of two variables and the generation of fractals. The main objective is to allow Technical School students in Numerical Computation subjects to acquire the skills to generate fractals and interpret their plots in terms of the convergence or divergence speed of the sequence of iterated.

Frequency of exposure of endangered Caspian seals to Canine distemper virus, Leptospira interrogans, and Toxoplasma gondii

2017

Canine distemper virus (CDV), Leptospira interrogans, and Toxoplasma gondii are potentially lethal pathogens associated with decline in marine mammal populations. The Caspian Sea is home for the endangered Caspian seal (Pusa caspica). In the late 1990s and early 2000s, CDV caused a series of mortality events involving at least several thousand Caspian seals. To assess current infection status in Caspian seals, we surveyed for antibodies to three pathogens with potential to cause mortality in marine mammals. During 2015-2017, we tested serum samples from 36, apparently healthy, Caspian seals, accidentally caught in fishing nets in the Caspian Sea off Northern Iran, for antibodies to CDV, L. …

The collaborative consistent vehicle routing problem with workload balance

2021

Abstract The rising competition in the logistics sector forces companies to be more economically efficient. One of the major sources of inefficiency is the incomplete usage of available resources, such as vehicles’ capacities. Mechanism that allow to better exploit such resources by enabling carrier collaborations are on the rise. Our study examines a centrally organized multi-period collaborative vehicle routing problem, where carriers can exchange customers who have to be serviced on a regular basis. Collaborations, where carriers serve frequent customers, are supposed to face the problem of (i) time consistency in terms of visiting time, and of (ii) service consistency. The latter ensure…
