For positive recurrent nearest-neighbour, semi-homogeneous random walks on the lattice {0, 1, 2, …} X {0, 1, 2, …} the bivariate generating function of the stationary distribution is analysed for the case where one-step transitions to the north, north-east and east at interior points of the state space all have zero probability. It is shown that this generating function can be represented by meromorphic functions. The construction of this representation is exposed for a variety of one-step transition vectors at the boundary points of the state space.

Ras a1 Khaimah is the most northerly of the seven states comprising the United Arab Emirates and its Ruler, H. H. Sheikh Saqr bin Mohammad al-Qasimi, is keenly interested in the history of the state and its people. Survey carried out there jointly with Dr D. B. Doe in 1968 had focused attention on the site of JuIfar which lies just north of the present town of Ras a1 Khaimah (de Cardi, 1971, 230-2). Julfar was in existence in Abbasid times and its importance as an entrep6t during the sixteenth and seventeenth centuries-the Portuguese Period-is reflected by the quantity and variety of imported wares to be found among the ruins of the city. Most of the sites discovered during the survey dated from that period but a group of cairns near Ghalilah and some long gabled graves in the Shimal area to the north-east of the date-groves behind Ras a1 Khaimah (map, FIG. I) clearly represented a more distant past.

The decision among human beings to change their places of residence has remained an age-long strategy of survival practiced for a very long time. However, the migratory activities associated with internal population displacement are often propelled by forced migration occasioned by natural or anthropogenic forces or a combination of both. The upsurge of internal population displacement in the Nigerian state is incontrovertible given the maniacal campaign of the Boko Haram insurgency in the North-east region. The dilemma of internally displaced persons and the imperative management have proven a formidable challenge to the Nigerian state. The aim of this paper therefore is to ethically investigate whether the ineffective control of the Boko Haram insurgency by the state is implicated in the rising incidence of internally displaced persons and evident vulnerabilities. The study adopted qualitative research which relied heavily on the documentary method of data collection and, guided by the ‘Marxist theory of the post-colonial state’ as a theoretical underpinning. The findings of this paper showed that the ineffective control of Boko Haram insurgency by the state was implicated in the rising incidence of internal population displacement in the North-east. The paper critically observed that the state and its agencies like the National Emergency Management Agency (NEMA), State Emergency Management Agencies (SEMAs), National Commission for Refugees, Migration and Internally Displaced Persons (NCFRMI), Presidential Initiative for the North East (PINE), Presidential Committee on the North-East Initiative (PCNI), among others have become the main instruments for the advancement of the interests of the dominant class. The study however recommends amongst other things that the state should ethically rethink its narrow strategy against Boko Haram insurgency through the adoption of a broader approach according to the dictates of Nigeria’s Countering Violent Extremism framework.

The present article focuses on the entity of middle classes in non-Western societies. The social formation of this kind is a relatively new phenomenon. As far as the modern Western societies are concerned, the social and political “materialization” of the above-mentioned entity has covered the period of no less than five centuries. The middle class in modern transitional societies began to emerge quite recently, with a few notable exceptions, after gaining sovereignty. That is one of the reasons why political systems in the non-Western world are mostly fragile and susceptible to instability of different kinds and origins. The so called “Arab awakening” gives a vivid example for the “underdevelopment” of indigenous middle classes. Whilst in the advanced industrial societies middle classes were (and are) the building blocks of social structure, economic and political development, elite recruitment, etc., among the non-Western societies (with the salient exception of the North-East Asia) the process of the middle class institutionalization as well as its economic and political self-assertion is still under way, somewhere at the initial stage of development. Comparing various non-Western societies from the middle class inner dynamics as well as self-assertion perspective, the author concludes that in the ultimate analysis, the maturity of this process is dependent on the pro-active and creative role of the State. The latter serves as the main driving force of the middle class consolidation and the instrument of political and economic systems for increasing and advancing development. The cases of India, on one hand, and Indonesia, on the other, demonstrate convincingly that the State remains the leading institution of the society able to accelerate economic growth and development, but also to stimulate the emergence and socio-political assertion of the middle class in contemporary non-Western world.

In the islands surprises seem to be as ἀνήριθμοι as the γέλασμα of the waves. If news came from anywhere else of the discovery of a circular marble slab carved with a head in relief, experience would lead the archaeologist to expect a late portrait or one of the so-called oscilla. Not so on Melos: here he finds himself confronted with the splendid head of a goddess carved in the purest Early Classical style.For such in fact is the fragment of a circular marble disc (Plate XXXVII and fig. 1) discovered in 1937 on the slopes of Klema, the site of the ancient town of Melos. It was found lying on the surface of the ground, on the property of Panagioulis Vikhos, to the north-east of Kalyvaki. The distinguished lawyer of Plaka, Mr. N. Kyritses, to whom we must again express our gratitude for having rescued it, readily offered it to the State.The disc is of Parian marble. Its convex obverse is decorated in relief with a head in profile to the right—an unusual subject. The reverse (fig. 2) is flat and smooth. The flat rim joining the two faces is 0·016 m. wide, but at the centre, where it is broken, the disc is 0·073 thick, not counting the height of the relief. The greatest preserved height of the fragment is 0·325 m., the greatest width 0–335.

This study examines the extent to which the Nigerian journalists comply with ethical values in the course of their reportage. Two national dailies – The Nation and Daily Trust newspapers were selected for content analysis, using systematic random sampling technique to pick 26 editions per newspaper. A period of six months from 14 December 2014 to 14 June, 2015, covering the 4th phase of the state of emergency was chosen. Tables, figures, and sample percentage counts were employed in making the research data easily understandable. The findings revealed that though the newspapers appeared to be ethically compliant in their reportage, none of the two newspapers was neutral in its reportage of the state of emergency rule. Majority of their stories were considered unpleasant and capable of aggravating the crisis in the troubled states. The hypothesis were tested, one showed that there is a significant difference between the number of news stories and the number of ethical breaches in the selected newspapers; hypothesis two showed a significant difference between ethically breaching and ethically standard reports/content of the selected newspapers; hypothesis three showed a significant difference between the ethical breaching of Daily Trust and those of The Nation –X2 = 0.09; P<0.05, df1. The study therefore, recommends that journalists should always have a healthy regard for the public interest, desist from slavish adulation and join hands with the government in bringing about lasting peace to the troubled states and desist from publishing inflammatory stories.

India is a co-habitation of different casts, socio-cultural, religious groups of people. It is also observed in Assam, the state in the North-East India. It should be noted that the state of Assam has a reputation worldwide in the field of tea production. Since the beginning of tea production in Assam in the 19th century, the Tea Community social group of Assam has been formed with a large number of people working hard in the tea gardens. In this way tea farmers living in Assam since 19th century have become an independent community with their own social and cultural characteristics. The Tea Community of Assam has a lot of individual Characteristics in the socio-cultural aspects. This study attempts to discuss their social folk customs and believes.

Assumptions are made by government and technology providers about the power relationships that shape the use of technological security controls and the norms under which technology usage occurs. We present a case study carried out in the North East of England that examined how a community might work together using a digital information sharing platform to respond to the pressures of welfare policy change. We describe an inductive consideration of this highly local case study before reviewing it in the light of broader security theory. By taking this approach we problematise the tendency of the state to focus on the security of technology at the expense of the security of the citizen. From insights gained from the case study and the subsequent literature review, we conclude that there are three main absences not addressed by the current designs of cybersecurity architectures. These are absences of: consensus as to whose security is being addressed, evidence of equivalence between the mechanisms that control behaviour, and two-way legibility. We argue that by addressing these absences the foundations of trust and collaboration can be built which are necessary for effective cybersecurity. Our consideration of the case study within the context of sovereignty indicates that the design of the cybersecurity architecture and its concomitant service design has a significant bearing on the social contract between citizen and state. By taking this novel perspective new directions emerge for the understanding of the effectiveness of cybersecurity technologies.
