Anarchist Cybernetics
Authors: Swann Thomas
Published: March 2021

From Occupy, to the Indignados and the Arab Spring, the uprisings that marked the last decade ignited a re-emergence of participatory democracy as a political ideal within organizations. This pioneering book introduces cybernetic thinking to politics and organizational studies to explore the continuing development of this radical idea. With a focus on communication and how alternative social media platforms present new challenges and opportunities for radical organising, it sheds new light on the concepts of self-organization, consensus decision making, individual autonomy and collective identity. Revolutionising the way in which anarchist activists and theorists think about organizations, this unprecedented investigation makes a major contribution to the larger discussion of direct democracy.
Fundamental Assumptions in Narrative Analysis: Mapping the Field
Authors: Robert Dominique , Shenhav Shaul
Published: March 2021

The richness of narrative analysis resides in its unruly openness, but points of reference are needed to tame the variety in the field. This article suggests that researchers should grapple with two fundamental questions when conducting narrative analysis. The first pertains to the status attributed to narrative: it is defined as the very fabric of human existence or as one representational device among others? Emphasizing one answer over the other means mobilizing different theories of representation and therefore, suggesting different articulations between "narrative" and "reality." The second question refers to the perspective developed on narrative: Is it defined mostly as the characteristic of an approach, an object of investigation or both? Different methodological implications are associated with that choice. The article claims that dominant trends in narrative analysis originate in the way researchers answer those two questions.
A Qualitative Analysis of Students' Perceptions of Pursuing Pharmacy as a Potential Vocation
Authors: Firmin Michael , Bouchard Valerie , Flexman Jordan , Anderson Douglas
Published: March 2021

We present the findings from a phenomenological, qualitative research study that explored the personal constructs of an inaugural class, entering a newly-established direct-entry, preferred admission, pre-pharmacy program at a private, selective, Midwestern university with an enrollment of 3000. The focus of the study was to appraise students' perceptions regarding their rationale for pursuing a future career in pharmacy. The sample consisted of 36 students (26 females, 10 males). Data was collected via in-depth interviews of each student who had enrolled in the first year of the program. Overall, students demonstrated their belief that they would be a good fit for the pharmacy field and looked forward to enjoying their future profession. Participants also expressed having a penchant for science and healthcare, and having previously interacted with pharmacists and the pharmacy field prior to entering college. Benefits such as salary, job security, and prestige were of secondary importance to students, but they played a role nonetheless, and encouragement from parents and other respected individuals also was significant.
From Learning Comes Meaning: Informal Comentorship and the Second-Career Academic in Education
Authors: Barrett Joe , Brown Hilary
Published: March 2021

Informal mentoring relationships develop out of mutual identification and the fulfillment of career needs. As new faculty, we struggled to balance and decipher all the various facets inherent in the research, service, and teaching responsibilities in our new roles. This paper chronicles an informal comentorship collaboration we struck up to support our efforts as second-career academics in the field of education, seeking to navigate our way through institutional resocialization at a mid-sized Canadian university. Using a collaborative autoethnographic approach, we collected data comprising handwritten notes, tape-recorded coversations, e-mail reflections, and metareflections crafted after scheduled meetings over the course of a single academic school year. We sought to link theory with practice while using our own stories, narratives, and lived experiences as a basis for understanding our respective journeys toward social health and well-being in the academy, as well as our proficiency and competence as new scholars. From our analysis, we were able to interpret more clearly our roles, responsibilities, and needs, as well as institutional and departmental culture and norms. We offer practical implications and five lessons we have learned regarding the use of informal comentorships as an approach to managing the institutional resocialization of second-career academics.
What They Left Behind: A Case Study of Teachers' Experiences with School Improvement at Evergreen Elementary School
Authors: Orange Amy
Published: March 2021

With the enactment of the No Child Left Behind Act, an unprecedented amount of pressure has been placed upon schools to increase student achievement. During the 2009-2010 school year, Evergreen Elementary School was in Year Four of school improvement for failing to make Annual Yearly Progress (AYP) in both reading and math. Drawing on observational and interview data from upper elementary school teachers, this paper will explore how striving to make AYP impacted teachers including increased workloads and stress, and how these factors led to teachers leaving the school, with a focus on a single teacher’s experiences.
Music, Musicians and Barroom Aggression
Authors: Roberts James , Mattern Kimberly
Published: March 2021

The purpose of this study was to explore the relationship between live bands and the music they play and aggression in barrooms catering to young, college-aged patrons. Twenty musicians representing 14 different cover bands playing in licensed drinking establishments throughout Northeast Pennsylvania were interviewed about their influence on the behaviors of bar patrons. Content analysis of completed interviews revealed several important findings. Most notably, each of the musicians interviewed in this study reported being able to control and manipulate patron behavior, not just through the music they play, but also through their stage presence, their physical appearance and attire, and the way they interact with patrons while on and away from the stage. While none of the musicians reported ever deliberately trying to push bar patrons towards aggression, most agreed that they had the power to do so if desired. Conversely, musicians identified themselves as potentially important agents of social control within bars. Implications for future research and policy are discussed.

Published: March 2021

This research work tries to unveil the changing teen’s behaviors in nuclear and joint family systems in Pakistan. Pakistan enjoys the social values of joint families; and, where grandparents are very important constituent of the family, the family structure is an important component in shaping the teens behaviors. Therefore, this paper focuses the sample of parents and teachers of the teens in the postmodern urban society and tried to better point out the eminent changes in the attitudes and behaviors of teens. This study follows a qualitative approach of research that pursues a phenomenological inquiry describing lived experience of the respondents regarding teen’s behavior in Pakistan.
The Use of Recursive Frame Analysis on an Emotionally Focused Couples Therapy Session
Authors: Peng Yanqun
Published: March 2021

Emotionally Focused Couples Therapy (EFT) is an evidence0based therapy model. It has been viewed as an empirical approach to couple therapy, and it has lasting treatment effects (Johnson, 2004; Greenman & Johnson, 2013). However, Greenman and Johnson (2013) also argued that there is still a lack of research concerning the EFT process. This study focuses on connections between theory and practice by analyzing the EFT process. Recursive Frame Analysis (RFA), a tool developed by Chenail and Keeney to map therapeutic conversation (Chenail, 1993; Chenail, 1995; Keeney, 1987), is used here as a research method to examine Sue Johnson’s use of EFT interventions and techniques to delivering EFT theory in the educational DVD titled, “Emotionally Focused Therapy in Action” (Johnson, 2011). Specifically, this study analyzes the conversational movement within and between the EFT stages and steps, to examine interventions and techniques related to interactional patterns, emotions, and attachment. It is a descriptive research. An analysis of the DVD session illustrates Johnson’s skills in using systemic interventions, experiential interventions, and attachment interventions and techniques linking EFT theories to practice. The skills of how and when to use specific interventions and techniques, as informed by a language perspective, can be very beneficial for therapists’ better understanding of the transitions and flows between EFT theories and practice. In addition, the researcher found that RFA as a research methodology is well-suited to analyzing an EFT session.

Parent-Adolescent Storytelling in Canadian-Arabic Immigrant Families (Part 2): A Narrative Analysis of Adolescents' Stories Told to Parents
Authors: Ashbourne Lynda , Baobaid Mohammed
Published: March 2021

This paper is the second of two papers presenting the results of a qualitative analysis of interviews inviting Arabic-Canadian immmigrant adolescents and parents to reflect on the stories they tell each other in the context of everyday family life. The first paper provides the results of a Grounded Theory Methodology and proposes a substantive theory of intergenerational storytelling during adolescence. This paper augments these results by presenting Narrative Analysis of a separate part of the interview inviting adolescents to tell a story to the interviewer as if telling it to their parents. Based on the stories told by 10 adolescents (5 male, 5 female), this analysis provides an initial representation of how the broad projects of acculturation and collective identity, as well as changes in parent-adolescent relationships, are brought directly into parent-adolescent day-to-day interaction in the form of small stories. These small stories present teens as performing in their day-to-day lives, with friends and strangers, and in the face of challengers and strange or familiar circumstances. The stories provide a context in which parent-adolescent interactional voices are prominent, and wherein understanding of unusual events, co-construction of self and family identities, broader social influences, and autonomy/connection dialectics emerge.
Great Expectations: The Mismatched Selves of a Beginning Teacher
Authors: DiCicco Michael , Sabella Laura , Jordan Robert , Boney Kate , Jones Pat
Published: March 2021

As university supervisors we were alerted to heightened emotional responses (i.e., crying, not eating, not sleeping), expressed by paid-interns in an accelerated Master of Arts in Teaching (M.A.T.) cohort of STEM practitioners. While research has shown teachers prepared in alternative programs tend to have greater difficulties (Darling-Hammond, 1990), few studies have examined alternatively prepared teachers’ beliefs and expectations about teaching and learning (Tigchlaar, Brouwer, & Vermut, 2010; Good et al., 2006). This inquiry describes one paid-intern’s teaching expectations during her first year of teaching. In this phenomenological case study, part of a larger cross-case study, we collected data from interviews, observation notes and university supervisor evaluations in an effort to answer: (1) What are the expectations about teaching of a student in an accelerated M.A.T. program who is also a first-year teacher completing a paid internship and (2) In what ways did she address those expectations? We utilized self-discrepancy theory (Higgins, 1987) that provides an understanding of how expectations can produce negative effects, such as anxiety or depression. Discoveries suggest the intern held idealistic expectations about teaching, influenced by her personality, prior experiences, and the accelerated M.A.T. program, which she could not reconcile with her experiences as a teacher.
Converting Capital: The Experiences of Latinas/os in Graduate Health Care Programs
Authors: Zell Maristela
Published: March 2021

This qualitative study combines critical race theory, cultural capital theory, and counter-storytelling to examine the experiences of Latina/o in graduate health care programs. Community cultural wealth provided the framework to investigate the mechanisms by which students converted their sociocultural assets into the kinds of social, cultural, and educational capital needed to succeed in a graduate program and pursue their career goals. A qualitative content analysis was employed to interpret participants’ conversion experiences. The forms of community cultural wealth described by Yosso – aspirational, linguistic, familial, navigational, social, and resistant – intersected and interacted with one another. Aspirational and linguistic forms of capital were converted into occupational attainment; familial capital was converted into educational and occupational outcomes; navigational and social forms of capital were converted into educational outcomes, and resistant capital was converted into civic engagement. Recommendations for practice and future research are discussed.
Expert Opinion? A Micro-Analysis of Eating Disorder Talk on Dr. Phil
Authors: LaMarre Andrea , Sutherland Olga
Published: March 2021

In this study, we explored how eating and identities of individuals diagnosed with eating disorders are constructed on a popular television talk show, Dr. Phil. Informed by conversation analytic and discursive psychological research traditions, we show how Dr. Phil, jointly with guests, constitutes guests as mentally ill and accountable for their illness. Specifically, we highlight Dr. Phil’s unilateral pursuit of a solution to the “puzzle” of the eating disorder, including its origins and meanings, as he enlists the guests’ endorsement of his versions of their situations and experiences. We examine broader implications of such a framing for societal understandings of the subjectivity of individuals diagnosed with eating disorders.
Uncovering ED: A Qualitative Analysis of Personal Blogs Managed by Individuals with Eating Disorders
Authors: Gies Jacqueline , Martino Sara
Published: March 2021

Previous studies have investigated the potential harmful effects of pro-eating disorder (ED) websites. Websites, such as personal blogs, may contain eating disorder content that may hold important information as well and must be considered. Fifteen blogs hosted by the site “Tumblr” were qualitatively analyzed. Each blog owner was anonymous and all were female. Ten main themes were extracted using grounded theory: interaction, negative self-worth, mind and body disturbances, pictures, eating disorders, suicide, diet, exercise, stats, and recovery. Additional themes also appeared in the study. Results indicate that although each individual blog is unique to its owner, common concepts existed among the majority. The implications for the information in the ED blogs and directions for future research are discussed.
Mothers of Sons with Substance Use Disorders: A Grounded Theory Approach Revealing Maternal Expectations and Three Stages of Change
Authors: Nelson Judith , Henriksen Richard , Keathley Roseanne
Published: March 2021

Addiction problems in a family present challenges in coping with the addicted family member's behaviors are often described in terms of the psychopathology of the interactions of the family members. The present article describes a qualitative study of the lived experiences of mothers whose male children have struggled or currently are struggling with chemical dependence. Our overall aim in the study was to explore critical stages or events in the experiences of these mothers relevant to their chemically dependent sons. As such, our research question was: What are the lived experiences of mothers of substance abusing sons who are either in recovery or are still using substances? Results of the interviews of nine mothers indicated that regardless of age, ethnicity, social status, education, or career, they experienced a process highlighted by maternal expectations and consisting of three stages: (a) the pre-addiction stage in which mother and son did not experience abnormal relational stress or conflict, (b) the addiction stage in which mother and son experienced extreme relational stress and conflict, and (c) the mother's recovery stage in which the mother experienced a confusion in her relationship with her son and his addiction leading to her own recovery and wellness.
Out of Our Comfort Zones: Reflections about Teaching Qualitative Research at a Distance
Authors: Hunter Cheyl , Ortloff Debora , Winkle-Wagner Rachelle
Published: March 2021

How does an increase in distance technology alter the teaching of qualitative research? This article uses a Scholarship of Teaching and Learning (McKinney, 2007) framework in which each author collected data in the form of personal narrative essays about teaching qualitative research from a distance, course products, teaching evaluations, and student comments. Individually we created a narrative reflection on the teaching and learning of qualitative methodology; particularly comparing our individual experiences with both distance and in-person teaching formats. Through these reflective essays, we provide ideas about our teaching of qualitative research via distance technology as a conceptual conversation about the nature of teaching qualitative research in non-face-to-face settings within schools of education. Looking across the essays we found that teaching qualitative methodology is rooted in relational ideas that may be difficult in a distance setting. We each individually struggled with the loss of time for learning new technology or traveling over a distance, which may have compromised the integrity of our other faculty job requirements. One common recommendation was that there be some level of face-to-face interaction, even over distance technologies, as a way to facilitate relational concepts in qualitative teaching.
Qualitative Perspectives toward Relational Connection in Pastoral Ministry
Authors: Young Jonathan , Firmin Michael
Published: March 2021

We present the results of a phenomenological, qualitative research study in which 13 Southern Baptist (SB) pastors were administered in-depth interviews. The sample was selected from a total of 37 exemplars, identified in the quantitative component of a larger mixed-methods study, regarding the pastors’ perspectives toward relational connection in pastoral ministry. Three themes emerged from the data regarding relational connection in pastoral ministry. First, pastors indicated the need to be intentional about pastoral connection. Second, the pastors stressed the importance of being available to congregants who specifically desire pastoral connection. Finally, the participants related that pastors should give particular attention to connections with lay church leaders.
Using Grounded Theory as a Method of Inquiry: Advantages and Disadvantages
Authors: Hussein Mohamed , Hirst Sandra , Salyers Vince , Osuji Joseph
Published: March 2021

There are many challenges and criticisms attached to the conduct of research, none the least of which is a notion that much of the research undertaken in professional disciplines such as nursing may not have clinical and/or practical relevance. While there are a plethora of qualitative research methods that individuals must consider when designing research studies, one method stands out - Grounded Theory (GT). Grounded theory was developed in the early 1960’s by Glaser and Strauss. With its theoretical orientation based in sociology, GT strives to understand and explain human behavior through inductive reasoning processes (Elliott & Lazenbatt, 2005). Because of its emphasis on the utilization of a variety of data sources that are grounded in particular contexts, GT provides a natural theoretical fit when designing nursing research studies. In this article, the authors provide an overview of GT and then describe the appropriateness, advantages, and disadvantages of applying it as part of the research design process. Additionally, the authors highlight the importance of taking a reflexive position to stay engaged while interacting with the data, and explore how to apply GT theory to particular research questions and studies. Finally, the strengths and limitations of this method of inquiry as applied to nursing research using a brief case study approach is presented.
New Emerging Technologies in Qualitative Research
Authors: Redlich-Amirav Dorit , Higginbottom Gene
Published: March 2021

According to Mayan (2009) being a qualitative researcher means to "enjoy living and learning with people to collectively make sense of our world. Qualitative research is not only done with people, it is also accomplished through people…" (p. 12). By virtue of its various definitions, qualitative research involves a great deal of human communication. Communication has a major role in all aspects of qualitative research from planning to execution. While many new qualitative research technologies have evolved over the past few decades, the most critical and influential ones are those related to communication technologies. As there is limited data about the use of communication technologies in qualitative research, the purpose of this paper is to provide an overview of the new emerging technologies in qualitative research. We provide descriptions of the evolving technologies and highlight the importance of qualitative researchers being up to date with these developments.
A Collaborative Autoethnographic Search for Authenticity Amidst the "Fake Real"
Authors: Walker Trenia , Taylor Colette
Published: March 2021

This manuscript explores the importance of "authenticity" for the maintenance self-identity for social justice educators in higher education. A collaborative dialogue between two female faculty authors of different ethnicities explores and interprets how to balance one’s own situated understanding of themselves, shared discourse community, and a social justice paradigm. The authors systematically juxtapose their reflections on their experiences as educators in higher education to examine points of similarity and difference. By sharing and interrogating their individual experiences in higher education, the authors argue that the relationship between authenticity, identity, and social justice is complex and multifaceted. The authors conclude by conceptualizing authenticity as a work strategy which plays a vital part in one’s search of her/his individual identity.
Authenticity in Constructivist Inquiry: Assessing an Elusive Construct
Authors: Shannon Patrick , Hambacher Elyse
Published: March 2021

Methodological rigor in constructivist inquiry is established through an assessment of trustworthiness and authenticity. Trustworthiness parallels the positivistic concepts of internal and external validity, focusing on an assessment of the inquiry process. Authenticity, however, is unique to constructivist inquiry and has no parallel in the positivistic paradigm. Authenticity involves an assessment of the meaningfulness and usefulness of interactive inquiry processes and social change that results from these processes. However, the techniques for ascertaining authenticity are in the early stages of development. Therefore, the purpose of this article is to describe a process for assessing authenticity in a constructivist inquiry. A brief overview of constructivist inquiries are described in relation to a set of techniques designed specifically to assess five dimensions of authenticity. Implications for constructivist researchers and social work research are presented.

Dasar-Dasar Filsafat Isyraqiyah Suhrawardi
Authors: Abdullah Miswar
Published: March 2021

Terdapat beberapa aliran filsafat yang muncul dalam peradaban Islam di antaranya seperti, mazhab Peripatetik atau filsafat Massya’iah dan juga mazhab Iluminasi atau filsafat Isyraqiyah. Peripatetisme Masysya’i menggunakan argumentasi rasional sebagai metode filosofis, dengan tokoh-tokohnya seperti Al-farabi dan Ibnu Sina. Sementara pada Iluminisme Isyraqi selain argumentasi rasional Suhrawardi Syeikh Isyraq yang merupakan tokoh utamanya, juga sangat menekankan penjernihan ruh serta riyadhah nafsani atau latihan spiritual bagi jiwa agar manusia memahami entitas dan hakikat-hakikat riil dengan jalan penyaksian, penglihatan batin, dll. Bahkan pada metode yang disebut terakhir ini proporsinya jauh lebih besar dari pada argumentasi rasional. Implikasinya Suhrawardi lebih mengutamakan prinsipilitas mahiyah sebagai sesuatu yang ashil ketimbang wujud. Pemahaman ini kemudian berdampak pada penerimaan cahaya yang menampakkan mahiyah sebagai realitas hakiki.
Performance Analysis of Brushless Motors with Segmented Cores considering Manufacturing Constraints
Authors: DUMITRU Andrei , VĂRĂTICEANU Bogdan , MINCIUNESCU Paul
Published: March 2021

Brushless servomotors are widely used in industry and in all domains that require precise and easy position/speed/torque control. To further improve the performance of these motors, the segmentation of the stator core is taken into account. This approach to core construction provides a high slot fill factor, compact design, and efficient use of materials. This paper aims to present that the manufacturing constraints and tolerances of this particular core construction can increase unwanted effects in brushless motors, like cogging torque, torque ripple and their influence regarding the back-EMF. Two models for a 12slots-10 pole configuration, one with segmented core and one with standard laminated core are compared and analysed using the FEA (Finite Element Analysis) method. The influence of the additional air gaps that occur in such constructions is investigated to provide an overview for the design of segmented motors. Various lengths for air gaps between the segments of the core are taken into consideration and non-uniform distribution of such gaps. The paper also provides further steps that must be taken in order to verify/validate the studied model’s impact on motor design.
Comparative Analysis of Line-start Synchronous Motor and Asynchronous Motor
Authors: SARAC Vasilija
Published: March 2021

Energy efficient motors are the key components of each industrial process. In the energy demanding society, requiring the energy efficient consumers, the line-start synchronous motor has gained more and more popularity due to the high efficiency and power factor combined with good operational characteristics. The disadvantages of the synchronous motors such as inability of starting without the inverter has been largely overcame with this type of the motor. However, the proper design of line-start motor regarding permanent magnets and the squirrel cage winding is crucial for motor starting and synchronization capability. In this paper, the line-start synchronous motor is derived from the asynchronous motor by redesigning the rotor. The obtained performance characteristics of the synchronous motor is compared with the data of the asynchronous motor (the analytical, measurements and from the motor producer) and they show reasonable agreement. The derived model of the synchronous motor is numerically modelled for obtaining the magnetic flux density distribution in the motor cross-section. The analysis and comparison is completed by obtaining the transient characteristics of both types of the motors. The designed synchronous motor has proven to have good starting and synchronization capabilities combined with the high efficiency. The dynamic response at sudden load changes is within expected limits.

Signal Conditioning provided by Sensitive Elements of Electric Bioimpedance Sensors
Authors: PÎSLARU-DĂNESCU Lucian , STOICA Victor , TELIPAN Gabriela
Published: March 2021

Dry polarizable electric bioimpedance sensors for ECG (electrocardiogram) monitoring requires the use of signal conditioning electronic circuits that take over alternating ΔU voltages with a frequency of 40 kHz and peak-to-peak amplitude in the range of 10-50 mV. The sensitive elements of these sensors are made of sensitive materials like as conductive polymer polypyrrole or hybrid nanocomposite with 10 and 20% Ag incorporated in the polypyrrole polymer. The useful signal is picked up in differential mode by an instrumentation amplifier. The gain of the instrumentation amplifier is set to A = 100 by connecting a single external resistor, RG. The problem of eliminating the mass loops and obtaining a common mode signal is solved by using an amplifier with galvanic isolation, with the amplification factor A = 1, supplied with double differential voltage. To reject any parasitic signals that may accompany the useful signal, an electronic bandpass filtering module is used. Electrical measurements were performed which showed the accuracy of the signal amplified by the electronic instrumentation amplifier module used in the "differential mode" connection.

This contribution intends to examine the works commissioned by Rai to Giosetta Fioroni and Pino Pascali, highlighting how these episodes are exemplary to understand the impact of the academic training from the intermediate stage of their artistic career, up to the synthesis made in the mature works of the two artists.
«Noi non riprendiamo la realtà: la inventiamo»: Eugenio Carmi
Authors: Barenghi Anna
Published: March 2021

In the late 1960s, at the invitation of Umberto Eco, Eugenio Carmi began to collaborate with Servizio Programmi Sperimentali in Rai. After some research on perception, the artist proposed an actual “transgression” for the use of television medium: using cameras not to film the reality, but to create a completely abstract color video work. From an exchange with Rai technicians, the idea was born to use in an artistic way the disturbance generated when you point a video camera at its own playback video monitor. Thus began the first Italian videoart experiments of so-called “feedback” process, to get between 1972 and 1974 to the documentary Arte elettronica, arte della luce and the video work C’era una volta un re, and then, in 1977, the animated fairy tale Olivo verde vivo created by the painter’s daughters Antonia and Francesca Carmi with Giulio Masoni.
La colpa in gioco Elementi del Trauerspiel (a partire da Benjamin)
Authors: Palma Massimo
Published: March 2021

The article discusses the theatrical form named Trauerspiel (baroque drama or mourning play), starting from the very elements that form its concept – play and mourning. Far from being identifiable with tragedy or from being reducible to a sort of anticipation of Romantic features, Trauerspiel expresses the traumas of subjectivity in early modern age, as it deals with religious and political turmoil. Taking inspiration from Walter Benjamin’s Ursprung des deutschen Trauerspiels, the article investigates some crucial elements of baroque mise-en-scène such as sovereignty, guilt, empathy, searching for further intersections with the theories of play by both Johan Huizinga and Georges Bataille.

Teknologi Cloud Computing dengan layanan Private Cloud Storage merupakan dan menjadi sebuah jawaban untuk permasalahan yang sering terjadi dikehidupan kita sehari-hari yaitu pada permasalahan penggunaan perangkat penyimpanan fisik seperti memory card, flashdisk dan harddisk dimana data-data yang ada didalamnya sering terjadi kerusakan seperti kerusakan fisik perangkat, terkena bad sector, terkena virus, perangkat hilang dan lain sebagainya seperti yang sering terjadi pada mahasiswa dan mahasiswi Politeknik Bisnis Indonesia Murni Sadar Pematangsiantar. Teknologi Cloud Storage yang akan dirancang bersifat private hanya untuk kalangan kampus dan pada jaringan lokal kampus yang tersedia. Perancangan sistem yang akan dilakukan menggunakan virtualisasi dengan Oracle VM VirtualBox. Sistem operasi menggunakan Ubuntu Server 14.04.6 LTS, Web Server menggunakan Apache2, DBMS (Database Management System) menggunakan Mariadb, Interpreter menggunakan PHP dan Content Management System (CMS) menggunakan Owncloud. Setelah perancangan sistem dilakukan kemudian sistem tersebut diimplementasikan pada VirtualBox setelah itu dilakukan pengujian sistem terhadap akses data ke sistem dengan Smartphone dan komputer sehingga didapatkan sebuah sistem yang dapat berjalan dan berfungsi dengan baik agar dapat meningkatkan efisiensi perkuliahan.

Para  el  manejo  de  Bemisia  spp.  en  cultivo  de  chile  criollo  (Capsicum  annum  L.),  se  evaluaron diferentes alternativas, entre ellas, los insecticidas químicos: endosulfan, malathion; los bioplaguicidas: Paecilomyces fumosoroseus, Beauveria bassiana; el extracto vegetales: Allium sp.; aceite mineral: Saf- t-side, los jabones: foca y vel rosita, en ciclo 2008. Se utilizó un diseño de bloques completos al azar con 4 repeticiones, evaluando las poblaciones de adultos, ninfas, y huevos a través de análisis de varianza y una prueba de comparación de medias. Los productos se aplicaron una vez por semana y se hicieron 6 aplicaciones semanales y se tomaron los datos de campo y laboratorio dos días después de cada aplicación. Se observa que los diferentes tratamientos con extractos, aceites, jabones, hongos y químicos los fueron capaces de mantener las poblaciones de adultos de Bemisia spp. en niveles mucho más  bajos  que  el  testigo,  durante  el  tiempo  que  duró  el  experimento.  Las  alternativas  donde  se utilizaron insecticidas químicos, hongos entomopatógenos y los extractos vegetales y aceites minerales fueron similares estadísticamente, y lograron niveles poblacionales de huevos relativamente bajos. En huevos la variante donde se utilizaron los jabones difirió significativamente de todas las demás, que no difirieron entre sí. Ninfas Todas las variantes evaluadas difirieron estadísticamente del testigo, y se observó el menor efecto de regulación de la población de ninfas en la variante con jabones, con diferencia significativa con relación a los demás tratamientos, después, se ubicó la variantes de hongos entomopatógenos, con extractos y aceites, y por último, la de insecticidas químicos que fue el que mayor efecto presento para el control de mosca blanca. Los resultados de este ensayo demuestran que todos los tratamientos difirieron estadísticamente del testigo y que reducen las poblaciones de mosca blanca, por lo que pueden utilizarse exitosamente como alternativa en el manejo integrado de esta plaga.

El presente trabajo analiza el mercado de la joyería artesanal en la Región de Tuxpan, Ver., con el fin de ofrecer una visión global y orientar a los emprendedores que se encuentran en el proceso de comercialización de bisutería artesanal obteniendo un conocimiento previo, intentando conseguir el éxito en sus proyectos. El sector de la bisutería en México ha experimentado profundos cambios con la llegada masiva de productos asiáticos al mercado, esto, debido a que estos son de muy bajo costo y lo que ha influido de manera radical en la producción local, impactando directamente en el volumen de la comercialización nacional y a las exportaciones, provocando caídas constantes en ambas cifras. Sin embargo, las importaciones crecen cada año desde 2002, México, tradicionalmente es joyero, donde los principales centros de producción están ubicados en Guadalajara y México, DF. La bisutería es una joyería artesanal y tradicional, que es consumida, no tan solo por mujeres, sin no también por hombres. La demanda de bisutería ha crecido y mantiene su tendencia de crecimiento, debido a que es un producto que permite seguir las tendencias de la moda de una manera más económica  y segura que la joyería. El motivo que impulsa a la compra de bisutería es más emocional que racional, y su asociación con las tendencias cambiantes de la moda hace que el ciclo del producto sea más corto.

La importancia de los ecosistemas de manglar es irrefutable por los innumerables beneficios que brindan en distintos ámbitos; sin embargo, pese al valor que se les atribuye, su tasa anual de deforestación en territorio mexicana es de aproximadamente 2.5%. En México, la extensión de manglares es de 764,486 hectáreas. Entre las especies que los conforman, se encuentra L. racemosa, una de las principales especies a nivel nacional. Las hojas son los órganos más sensibles de las plantas a la contaminación y sirven como indicadores de alteraciones a condiciones ambientales ya que refleja cambios en las características estomáticas lo cual es relevante por la importancia de los estomas en la homeostasis de las plantas. El objetivo de este estudio fue determinar macro- y micro-características foliares de plantas de L. racemosa en dos zonas del sitio Ramsar 1602, una al norte (deteriorada) y otra al sur (no deteriorada) del Río Tuxpan.   Se consideraron 12 individuos al azar de cada localidad para obtener material vegetal. El promedio del área de la hoja fue mayor en la Zona no deteriorada, caso contrario con los valores obtenidos para longitud, ancho, densidad e índice estomático, ya que éstas variables fueron mayores en la zona deteriorada.

El tepetate es un horizonte endurecido con baja retención de humedad y fertilidad, restrictivas para el desarrollo de especies vegetales; sin embargo, puede mejorar esta condición a través de prácticas de rehabilitación, como lo es el empleo de leguminosas. Se determinó la potencialidad de diferentes poblaciones de Lupinus campestris como alternativa para rehabilitar y mejorar la calidad productiva de los  tepetates  de la hacienda San  Antonio  Tepetzala, localizada en  el  municipio  de Atlangatepec, Tlaxcala. Se estableció un diseño experimental en bloques completamente al azar, los tratamientos fueron nueve poblaciones de L. campestris procedentes del estado de Puebla. A los 12 meses se llevó a cabo  el  muestreo  de  tepetate  de  la  zona  rizosférica  de  las  leguminosas,  para  evaluar  el  pH, conductividad eléctrica, materia orgánica, capacidad de intercambio catiónico, N total, P, K, Ca y Mg. Los resultados mostraron una diferencia significativa (p<0.05) después del establecimiento de la planta,pero no entre poblaciones. Si bien los valores de cada una de las variables determinadas con base a la normatividad mexicana fueron bajos,es notoria la mejora a un año de establecer diferentes poblaciones de L. campestris en el tepetate. Por lo que se concluye que L. campestris puede mejorar las características del tepetate, lo que la convierte en una excelente candidata para la rehabilitación de zonas degradadas.
