Distance Education System

Abstrak Memasuki era 4.0, segala sektor dalam aktivitas kehidupan sudah mulai terdigitalisasi, begitupun yang terjadi dalam sektor pendidikan. Selain itu kondisi Pandemi COVID-19 mewajibkan aktivitas pembelajaran dilakukan di rumah. Hal tersebut tentunya menuntut peran teknologi digital untuk mendukung sistem pendidikan jarak jauh atau yang lebih dikenal PJJ. Namun dalam penerepan sistem pendidikan jarak jauh tentunya tidak mudah dan banyak hal yang menjadi kendala-kendala dalam sistem pembelajaran tersebut, hal ini disebabkan beberapa hal antara lain kesiapan guru dan siswa menghadapi proses pembelajaran yang berbeda dari sebelumnya dan juga model dari desain pembelajaran yang tentunya perlu di sesuaikan agar hasil dari pembelajaran dapat tetap maksimal. Tentunya banyak alternatif model pembelajaran dalam sistem pembelajaran jarak jauh, salah satu yang dapat diterapkan pada situasi saat ini ialah Model Flex blanded learning. Abstract Entering the 4.0 era, all sectors in life activities have begun to be digitized, as has happened in the education sector. In addition, the COVID-19 pandemic condition requires learning activities to be carried out at home. This of course demands the role of digital technology to support the distance education system or better known as PJJ. However, in implementing the distance education system, it is certainly not easy and many things become obstacles in the learning system, this is due to several things, including the readiness of teachers and students to face a different learning process than before and also the model of learning design which of course needs to be implemented. adjusted so that the results of learning can remain maximal. Of course, there are many alternative learning models in distance learning systems, one of which can be applied to the current situation is the Flex blended learning model.

Corporate Social

In this conceptual article, we argue that defining corporate social responsibility (CSR) and corporate social irresponsibility (CSI) as opposite constructs produces a lack of clarity between responsible and irresponsible acts. Furthermore, we contend that the treatment of the CSR and CSI concepts as opposites de-emphasizes the value of CSI as a stand-alone construct. Thus, we reorient the CSI discussion to include multiple aspects that current conceptualizations have not adequately accommodated. We provide an in-depth exploration of how researchers define CSI and both identify and analyze three important gray zones between CSR and CSI: (a) the role of harm and benefit, (b) the role of the actor and intentionality, and (c) the role of rectification. We offer these gray zones as factors contributing to the present lack of conceptual clarity of the term CSI, as a concept in its own right, leading to difficulties that researchers and managers experience in categorizing CSI acts as distinct from CSR.

Recent developments in Western societies have motivated a growing consideration of the role of negativity in public opinion and political behavior research. In this article, we review the scant (and largely disconnected) scientific literature on negativity and political behavior, merging contributions from social psychology, public opinion, and electoral research, with a view on developing an integrated theoretical framework for the study of negative voting in contemporary democracies. We highlight that the tendency toward negative voting is driven by three partly overlapping components, namely, (1) an instrumental–rational component characterized by retrospective performance evaluations and rationalization mechanisms, (2) an ideological component grounded on long-lasting political identities, and (3) an affective component, motivated by (negative) attitudes toward parties and candidates. By blueprinting the systematic relationships between negative voting and each of these components in turn, and suggesting multiple research paths, this article aims to stimulate future studies on negative voting in multi-party parliamentary systems to motivate a better understanding of the implications of negativity in voting behavior in contemporary democracies.

Granule Secretion

Fura 2 is one of a recently-introduced family of Ca++ indicators with improved fluorescent properties compared to quin 2 (Grynkiewicz et al 1985). This study has examined the role of [Ca++]i in thrombin-induced dense granule release using prostacyclin-washed human platelets loaded with either thedense granule marker 14C-5HT (5HT) alone or with 5HT together with quin 2 ([quin2]i = 0.8mM) or fura 2 ([fura 2]i 20-30µM). In the presence of ImM extracellular calcium concentration ([Ca++]i) the [Ca++]e in quin 2 and fura 2 loaded platelets was 93±2 (n=10 experiments) and 133±0.3nM (n=12 experiments) respectively. In either quin 2 or fura 2 loaded platelets suspended in the presence of ImM [Ca++]e, thrombin (0.23-23.InM) promoted a rapid (in secs)concentration-dependent elevation of [Ca++]i from basal values to levels l-2µM, together with a parallel release of dense granules almost identical to that obtained with thrombin in non dye loaded platelets. In fura 2 loaded cells, removal of [Ca++]e inhibited the elevation of [Ca++]i induced by a sub-maximal concentration of thrombin (0.77nM) by 43+5% (n=4) but interestingly had no significant effect (p<0.05) on the rise in [Ca++]i elicited by low thrombin doses (0.231nM). Neither did lowering [Ca++]e inhibit the release of 5HT evoked by thrombin ( 0.231-23.InM) from either fura 2 loaded or non dye loaded platelets. In contrast, in quin 2 loaded platelets, removal of [Ca++]e inhibited the thrombin (0.231-23.InM) stimulated rise in [Ca++]i-by 90% and the 5HT release response to either low (0.231nM), sub-maximal (0.77nM) or maximal (23.InM) thrombin by 100% (n=4), 87+2°/o (n=6)and 2+l°/o (n=4) respectively. Fura 2 but not quin 2 loaded cells suspended in ImM [Ca++]e exhibited a Ca++ response to thrombin concentrations >2.31nM which could be separated into a rapid phasic component and a more sustained 'tonic' like component inhibitable by removal of [Ca++]e or by addition of ImM Ni++ . These data suggest the use of fura 2 rather than quin 2 for investigating stimulus response coupling in platelets, particularly when [Ca++]e is less than physiological.

Why do united rebel fronts emerge in some insurgencies, while in other insurgencies multiple rebel groups mobilize independently to challenge the state, and often, each other? I develop a diffusion model of rebel fragmentation in which participation in rebellion spreads, completely or incompletely, through networks of civilians and dissidents. Using this theoretical framework I hypothesize that two factors jointly determine whether a rebel movement remains unified or fragments: the rebels’ investment in civilian mobilization, and the overall level of civilian grievances. The theory predicts that widely shared grievances motivate the formation of many small dissident groups willing to challenge the regime. Given the difficulty of collective action between disparate opposition actors, an emerging rebel movement will tend towards fragmentation when popular grievances are high. Yet extremely high civilian grievances can also help rebels activate broad, overlapping civilian social networks that serve to bridge together dissident groups. Mass-mobilizing rebel groups, benefiting from the participation of broad civilian networks, are most likely to forge and maintain a unified rebel front. I test this theory alongside several alternatives drawn from cross-national studies of conflict using regression analysis. The quantitative evidence lends considerable credence to the role of rebel constituencies in preventing or fomenting rebel fragmentation.
