The underlying goal of FPGA architecture research is to devise flexible substrates that implement a wide variety of circuits efficiently. Contemporary FPGA architectures have been optimized to support networking, signal processing, and image processing applications through high-precision digital signal processing (DSP) blocks. The recent emergence of machine learning has created a new set of demands characterized by: (1) higher computational density and (2) low precision arithmetic requirements. With the goal of exploring this new design space in a methodical manner, we first propose a problem formulation involving computing nested loops over multiply-accumulate (MAC) operations, which covers many basic linear algebra primitives and standard deep neural network (DNN) kernels. A quantitative methodology for deriving efficient coarse-grained compute block architectures from benchmarks is then proposed together with a family of new embedded blocks, called MLBlocks. An MLBlock instance includes several multiply-accumulate units connected via a flexible routing, where each configuration performs a few parallel dot-products in a systolic array fashion. This architecture is parameterized with support for different data movements, reuse, and precisions, utilizing a columnar arrangement that is compatible with existing FPGA architectures. On synthetic benchmarks, we demonstrate that for 8-bit arithmetic, MLBlocks offer 6× improved performance over the commercial Xilinx DSP48E2 architecture with smaller area and delay; and for time-multiplexed 16-bit arithmetic, achieves 2× higher performance per area with the same area and frequency. All source codes and data, along with documents to reproduce all the results in this article, are available at http://github.com/raminrasoulinezhad/MLBlocks .

<p style="text-align: justify;">The emergence of digital technologies and a more global and digital society has brought about the need to develop and educate in Digital Citizenship, as well as to study how youth are taught to participate and learn citizenship in a digital age. This paper aims to explore the role of digital and socio-civic skills development, as facilitators for youth participation and analyses the relationship between sociodemographic variables (sex, age, educational level, and political ideology) with the participatory profile of participants. This is a study with a quantitative methodology, where, based on non-probabilistic convenience sampling, 534 young people between 16 and 35 years old from Spain, completed an online questionnaire regarding the development of digital and socio-civic skills. The results indicate how a participant’s participatory profile is related to other variables. In addition, significant differences are observed between the different participation profiles and digital and socio-civic skills, underlining that the development of digital and socio-civic skills are essential for educating in digital citizenship.</p>

  Los objetivos del presente estudio fueron analizar la influencia de la edad y tipo de ocupación relacionada con el empleo y la crianza, en las barreras para la práctica de las mujeres adultas en España. La metodología de carácter cuantitativa, se ha apoyado en el uso de la encuesta mediante el empleo de un cuestionario basado en la teoría bio-ecológica de Bronfenbrenner, con ítems individuales, ocupación crianza-hogar, ocupación empleo-tiempo y oferta de actividad física y deporte, a una muestra representativa de 1.731 mujeres adultas españolas (entre 30 y 64 años). Los resultados evidenciaron efecto multivariado de la ocupación en las barreras ocupación-empleo y tiempo (“No soy capaz de generar tiempo para mí”, “empleo” y “horarios incompatibles”). Las mujeres adultas que concilian maternidad y empleo perciben en mayor grado estas tres barreras mencionadas. Además, se evidenció efecto multivariado de la edad y la ocupación, y de la interacción, en las barreras ocupación maternidad-hogar (“Tengo que cuidar de mi/s hijo/as” y “Tengo que ocuparme de las tareas del hogar”). Las madres adultas, empleadas o no, percibieron la maternidad en mayor grado como barrera. En las empleadas que no son madres, las tareas del hogar como barrera tuvieron mayor prevalencia en las mayores de cincuenta años. Estas evidencias deberían considerarse para diseñar innovaciones y adaptar intervenciones, en el ámbito de la actividad física y el deporte, para estos grupos específicos, de mujeres adultas.  Abstract. The objectives of the present paper were to analyze the age and occupation type related to employment and maternity influencing Spanish adult women’s barriers to practice. A quantitative methodology based on the use of the survey was applied to a representative sample of 1,731 Spanish adult women (between 30 and 64 years old) who filled out a questionnaire based on the Bronfenbrenner´s bioecological theory with individual items, occupation maternity-household, occupation employment-time and physical activity and sport provision through a personal interview. The results showed a multivariate effect of the occupation on the occupation-employment and time barriers (“I can´t generate time for myself”, “employment” and “incompatible timetables”). The adult women who combine maternity and employment perceived the three barriers mentioned to a greater extent. Also, there was found a multivariate effect of age and occupation, and of the interaction, on the occupation maternity-household barriers (“I have to take care of my children” and “I have to do the housework”). The adult mothers, employed or unemployed, perceived maternity as a barrier to a greater degree. In employed women who are not mothers, household chores as a barrier showed a higher prevalence in those over fifty years old. These findings should be considered for designing innovations and tailoring interventions in the field of physical activity and sport to fit these targeted groups of adult women.

Purpose—This study aims to demonstrate the antecedent factors of consumers’ cosmetics purchasing behaviour in the emerging market of Thailand from the perspective of sustainability. Specifically, the study aims to quantitatively analyse the impact of three hypothesised antecedents of consumer behaviour: product quality, communicating sustainability, and ethical business behaviour. Methodology—A quantitative methodology is applied in the study, which collects survey data from Thailand. This study focuses on two cosmetic brands in Thailand, a domestic brand and an international brand. The total 800-sample dataset was analysed using Structural Equation Modelling to validate a conceptual model with measurements of three antecedent factors: quality, ethical behaviour, and communication sustainability. Findings—It is found that ‘ethical behaviour of the producers had a non-significant impact for all samples and the ‘domestic brand’, whereas communicating sustainability had a significant impact in all sample cases. The proposed measurement scales present a practical and pioneering tool for assessing consumer responses and behaviour towards cosmetic brands. The set of scales will also help cosmetics marketers to appraise their strategic planning and monitor their progress toward creating and identifying consumer loyalty to cosmetics brands via producers’ ethical behaviour and CSR messaging. Originality—The global market and inter-stakeholder communications have greatly changed the way people perceive, behave towards, and react to business suppliers. The understanding of consumer brand loyalty in the cosmetics industry and the business strategies focused on the impact of communicating sustainability with ethical behaviour remain limited, especially in the context of the emerging market. This research contributes to filling this gap with empirical analyses.
